Sample records for kidney donation rates

  1. Standardized deceased donor kidney donation rates in the UK reveal marked regional variation and highlight the potential for increasing kidney donation: a prospective cohort study† (United States)

    Summers, D. M.; Johnson, R. J.; Hudson, A. J.; Collett, D.; Murphy, P.; Watson, C. J. E.; Neuberger, J. M.; Bradley, J. A.


    Background The UK has implemented a national strategy for organ donation that includes a centrally coordinated network of specialist nurses in organ donation embedded in all intensive care units and a national organ retrieval service for deceased organ donors. We aimed to determine whether despite the national approach to donation there is significant regional variation in deceased donor kidney donation rates. Methods The UK prospective audit of deaths in critical care was analysed for a cohort of patients who died in critical care between April 2010 and December 2011. Multivariate logistic regression was used to identify the factors associated with kidney donation. The logistic regression model was then used to produce risk-adjusted funnel plots describing the regional variation in donation rates. Results Of the 27 482 patients who died in a critical care setting, 1528 (5.5%) became kidney donors. Factors found to influence donation rates significantly were: type of critical care [e.g. neurointensive vs general intensive care: OR 1.53, 95% confidence interval (CI) 1.34–1.75, P69 vs age 18–39 yr: OR 0.2, 0.15–0.25, Pdonation rates for the 20 UK kidney donor regions showed marked variation. The overall standardized donation rate ranged from 3.2 to 7.5%. Four regions had donation rates of >2 standard deviations (sd) from the mean (two below and two above). Regional variation was most marked for donation after circulatory death (DCD) kidney donors with 9 of the 20 regions demonstrating donation rates of >2 sd from the mean (5 below and 4 above). Conclusions The marked regional variation in kidney donation rates observed in this cohort after adjustment for factors strongly associated with donation rates suggests that there is considerable scope for further increasing kidney donation rates in the UK, particularly DCD.

    To review ethical, legal and technical aspects of living kidney donor surgery. An exhaustive systematic review of the scientific literature was performed in the Medline database ( and Embase ( using different associations of the following keywords: Donor nephrectomy; Kidney paired donation; Kidney transplantation; Laparoscopic nephrectomy; Living donor; Organs trafficking; Robotic assisted nephrectomy; Vaginal extraction. French legal documents have been reviewed using the government portal ( Articles were selected according to methods, language of publication and relevance. A total of 6421 articles were identified; after careful selection, 161 publications were considered of interest and were eligible for our review. The ethical debate focuses on organ shortage, financial incentive, organ trafficking and the recent data suggesting a small but significant increase risk for late renal disease in donor population. Legal decisions aim to increase the number of kidneys available for donation, such as kidney-paired donation that faces several obstacles in France. Laparoscopic approach became widely used, while robotic-assisted donor nephrectomy failed to demonstrate improved outcome as compared with other minimal invasive techniques. Minimally invasive living donor nephrectomy aims to limit side effects in the donor without increasing the morbidity in this specific population of healthy persons; long term surveillance to prevent the onset of renal disease in mandatory.

    The impact of kidney donation on the ability to change or initiate health or life insurance following donation is unknown. To quantify this risk, we surveyed 1046 individuals who donated a kidney at our center between 1970 and 2011. Participants were asked whether they changed or initiated health or life insurance after donation, and if they had any difficulty doing so. Among 395 donors who changed or initiated health insurance after donation, 27 (7%) reported difficulty; among those who reported difficulty, 15 were denied altogether, 12 were charged a higher premium and 8 were told they had a preexisting condition because they were kidney donors. Among 186 donors who changed or initiated life insurance after donation, 46 (25%) reported difficulty; among those who reported difficulty, 23 were denied altogether, 27 were charged a higher premium and 17 were told they had a preexisting condition because they were kidney donors. In this single-center study, a high proportion of kidney donors reported difficulty changing or initiating insurance, particularly life insurance. These practices by insurers create unnecessary burden and stress for those choosing to donate and could negatively impact the likelihood of live kidney donation among those considering donation. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

  6. Patients' willingness to talk to others about living kidney donation. (United States)

    Rodrigue, James R; Cornell, Danielle L; Kaplan, Bruce; Howard, Richard J


    Living donor kidney transplantation has several advantages for patients with end-stage renal disease. However, many patients are reluctant to pursue this treatment option, preferring instead to wait for a deceased donor organ. To examine predictors of patients' willingness to talk to others about living kidney donation. One hundred thirty-two adult patients awaiting kidney transplantation who were enrolled in a randomized trial examining the effectiveness of education on rates of live donor kidney transplantation completed a baseline rating of their willingness to talk to others about living kidney donation. Also, patients completed measures of knowledge and concerns about living donation and a rating of perceived health. Slightly more than half the patients (56.1%) had low willingness to talk to others about living donation. The following variables were associated with higher willingness to talk to others: white race (odds ratio, 3.31; confidence interval, 1.7-7.4), college education (odds ratio, 3.43, confidence interval, 2.0-5.6), fewer concerns about living donor kidney transplantation (odds ratio, 0.31; confidence interval, 0.2-0.6), and less favorable perceptions of their current health status (odds ratio, 4.31; confidence interval, 2.6-7.6). White race, more education, less concern about living donor kidney transplantation, and poorer perceived health are associated with greater willingness to talk to others about living kidney donation. These findings have important implications for educating patients about living donor kidney transplantation.

  7. Kidney organ donation: developing family practice initiatives to reverse inertia (United States)


    Background Kidney transplantation is associated with greater long term survival rates and improved quality of life compared with dialysis. Continuous growth in the number of patients with kidney failure has not been matched by an increase in the availability of kidneys for transplantation. This leads to long waiting lists, higher treatment costs and negative health outcomes. Discussion Misunderstandings, public uncertainty and issues of trust in the medical system, that limit willingness to be registered as a potential donor, could be addressed by community dissemination of information and new family practice initiatives that respond to individuals' personal beliefs and concerns regarding organ donation and transplantation. Summary Tackling both personal and public inertia on organ donation is important for any community oriented kidney donation campaign. PMID:20478042

    Living kidney donation is currently the most important kidney donor source in Latin America, and it is necessary to further increase its rates. To analyze the attitude toward living kidney donation among the Santiago de Cuba's population and to determine the sociopersonal factors with which it is associated. The population over 15 years old residing in Santiago de Cuba, stratified by sex and age, was screened. The "PCID-LKD Ríos" attitude questionnaire toward living kidney donation was administered to a random selection of the people surveyed according to the stratification and the census data. The completion was anonymized and self-administered. Verbal consent was obtained. The study was completed by 445 people, of whom the 86% (n = 389) were in favor of living related kidney donation. This attitude is associated with the level of education (P donation (P = .006); attitude toward cadaveric organ donation (P donation (P = .001); religious beliefs (P = .001); and assessment of the risk of living kidney donation (P donation; (3) carrying out of prosocial activities; and (4) risk assessment of living donation. Living related donation is very well accepted among the Santiago de Cuba's population. Copyright © 2017 Elsevier Inc. All rights reserved.

  9. Marital Status and Return to Work After Living Kidney Donation. (United States)

    Frech, Adrianne; Natale, Ginny; Hayes, Don; Tumin, Dmitry


    Living kidney donation is safe and effective, but patients in need of a transplant continue to outnumber donors. Disincentives to living donation include lost income, risk of job loss, perioperative complications, and unreimbursed medical expenses. This study uses US registry and follow-up data on living kidney donors from 2013 to 2015 to identify social predictors of return to work across gender following living kidney donation. Using logistic regression, we find that predictors of return to work following living kidney donation differ for women and men. Among women, age, education, smoking status, and procedure type are associated with return to work. Among men, education, procedure type, and hospital readmission within 6 weeks postdonation are associated with return to work. Notably, single and divorced men are less likely to return to work compared to married men (odds ratio [OR] for single men 0.51, 95% confidence interval [CI], 0.37-0.69, P donation.

  10. Live kidney donations and the ethic of care. (United States)

    Kane, Francis; Clement, Grace; Kane, Mary


    In this paper, we seek to re-conceptualize the ethical framework through which ethicists and medical professionals view the practice of live kidney donations. The ethics of organ donation has been understood primarily within the framework of individual rights and impartiality, but we show that the ethic of care captures the moral situation of live kidney donations in a more coherent and comprehensive way, and offers guidance for practitioners that is more attentive to the actual moral transactions among donors and recipients. A final section offers guidelines for the practice of live kidney transplants that emerge from an ethic of care.

    Maggiore, Umberto; Budde, Klemens; Heemann, Uwe


    Two recent matched cohort studies from the USA and Norway published in 2014 have raised some concerns related to the long-term safety of kidney living donation. Further studies on the long-term risks of living donation have since been published. In this position paper, Developing Education Science...... and Care for Renal Transplantation in European States (DESCARTES) board members critically review the literature in an effort to summarize the current knowledge concerning long-term risks of kidney living donation to help physicians for decision-making purposes and for providing information...... to the prospective live donors. Long-term risk of end-stage renal disease (ESRD) can be partially foreseen by trying to identify donors at risk of developing ‘de novo’ kidney diseases during life post-donation and by predicting lifetime ESRD risk. However, lifetime risk may be difficult to assess in young donors...

    There are three categories of deceased donors of kidney transplantation in China, donation after brain death (DBD), donation after circulatory death (DCD), and donation after brain death followed by circulatory death (DBCD) donors. The aim of this study was to compare the outcomes of kidney transplantation from these three categories of deceased donors. We retrospectively reviewed 469 recipients who received deceased kidney transplantation in our hospital from February 2007 to June 2015. The recipients were divided into three groups according to the source of their donor kidneys: DBD, DCD, or DBCD. The primary endpoints were delayed graft function (DGF), graft loss, and patient death. The warm ischemia time was much longer in DCD group compared to DBCD group (18.4 minutes vs 12.9 minutes, P < .001). DGF rate was higher in DCD group than in DBD and DBCD groups (22.5% vs 10.2% and 13.8%, respectively, P = .021). Urinary leakage was much higher in DCD group (P = .049). Kaplan-Meier analysis showed that 1-, 2-, and 3-year patient survivals were all comparable among the three groups. DBCD kidney transplantation has lower incidences of DGF and urinary leakage than DCD kidney transplant. However, the overall patient and graft survival were comparable among DBD, DCD, and DBCD kidney transplantation. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  14. Increasing access to kidney transplantation in countries with limited resources: the Indian experience with kidney paired donation. (United States)

    Kute, Vivek B; Vanikar, Aruna V; Shah, Pankaj R; Gumber, Manoj R; Patel, Himanshu V; Engineer, Divyesh P; Modi, Pranjal R; Shah, Veena R; Trivedi, Hargovind L


    According to the Indian chronic kidney disease registry, in 2010 only 2% of end stage kidney disease patients were managed with kidney transplantation, 37% were managed with dialysis and 61% were treated conservatively without renal replacement therapy. In countries like India, where a well-organized deceased donor kidney transplantation program is not available, living donor kidney transplantation is the major source of organs for kidney transplantation. The most common reason to decline a donor for directed living donation is ABO incompatibility, which eliminates up to one third of the potential living donor pool. Because access to transplantation with human leukocyte antigen (HLA)-desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end stage kidney disease patients. KPD is a rapidly growing and cost-effective living donor kidney transplantation strategy for patients who are incompatible with their healthy, willing living donor. In principle, KPD is feasible for any centre that performs living donor kidney transplantation. In transplant centres with a large living donor kidney transplantation program KPD does not require extra infrastructure, decreases waiting time, avoids transplant tourism and prevents commercial trafficking. Although KPD is still underutilized in India, it has been performed more frequently in recent times. To substantially increase donor pool and transplant rates, transplant centres should work together towards a national KPD program and frame a uniform acceptable allocation policy. © 2014 Asian Pacific Society of Nephrology.

  15. Long-term quality of life after living kidney donation. (United States)

    Glotzer, O S; Singh, T P; Gallichio, M H; Conti, D J; Siparsky, N F


    The supply of deceased donor kidneys available for transplantation is not sufficient to meet the demand. Despite a low rate of complications for donors and superior outcomes for recipients, living kidney donation (LKD) is on the decline for reasons that remain unclear. We performed a retrospective review and analysis of living kidney donors (LDs) who underwent donor nephrectomy between January 1, 2000 and December 31, 2010. Candidates who were excluded from LKD were identified as control subjects (CSs). LDs and CSs were invited to voluntarily undergo a quality of life assessment using Short Form 12 v1.0 Questionnaire (SF-12) and an addendum questionnaire (AQ). The SF-12 and AQ were administered by telephone. Statistical analysis of the results was performed to obtain the SF-12 physical component score (PCS), SF-12 mental component score (MCS), and the AQ score. PCS and MCS for the general population were obtained from the 1998 National Survey of Functional Health Status. During the study period, 83 LDs and 116 CSs were interviewed. LDs were noted to have higher PCS (54.1 vs 49.6) and MCS (55.7 vs 49.4) compared with the general population. Ninety-nine percent of LDs believed that their quality of life did not decrease after LKD; 21.7% reported experiencing complications. Half of the LDs (48%) reported missing 1 day of work for evaluation; 71% of LDs reported missing at least 4 weeks of work after LKD. Nearly all LDs (99%) would undergo donation again. Fifty-two percent of LDs reported adhering to the recommended 2-year follow-up schedule with the transplantation team; 87% of LDs reported seeing their primary care physician. LDs are physically and mentally healthier after LKD compared to the general population. Most donors miss at least 1 month of work for LKD and undergo some form of post-donation monitoring. Despite this commitment, LKD is a very satisfying experience. Copyright © 2013 Elsevier Inc. All rights reserved.

  17. Gout after living kidney donation: Correlations with demographic traits and renal complications (United States)

    Lam, Ngan N.; Garg, Amit X.; Segev, Dorry L.; Schnitzler, Mark A.; Xiao, Huiling; Axelrod, David; Brennan, Daniel C.; Kasiske, Bertram L.; Tuttle-Newhall, Janet E.; Lentine, Krista L.


    Background The demographic and clinical correlates of gout after living kidney donation are not well described. Methods Using a unique database that integrates national registry identifiers of U.S. living kidney donors (1987-2007) with billing claims from a private health insurer (2000-2007), we identified post-donation gout based on medical diagnosis codes or pharmacy fills for gout therapies. The frequencies and demographic correlates of gout after donation were estimated by Cox regression with left- and right-censoring. We also compared rates of renal diagnoses among donors with and without gout, matched 1:3 by age, sex, and race. Results The study sample of 4,650 donors included 13.1% African-Americans. By seven years, African-Americans were almost twice as likely to develop gout as Caucasian donors (4.4% vs. 2.4%; adjusted hazard ratio, aHR, 1.8; 95% confidence interval, CI, 1.0–3.2). Post-donation gout risk also increased with older age at donation (aHR per year 1.05) and was higher in men (aHR 2.80). Gout rates were similar in donors and age- and sex-matched general non-donors (rate ratio 0.86, 95% CI 0.66–1.13). Compared to matched donors without gout, donors with gout had more frequent renal diagnoses, reaching significance for acute kidney failure (rate ratio 12.5; 95% CI 1.5–107.0), chronic kidney disease (rate ratio 5.0; 95% CI 2.1–11.7), and other disorders of the kidney (rate ratio 2.2; 95% CI 1.2–4.2). Conclusion Donor subgroups at increased risk of gout include African-Americans, older donors, and men. Donors with gout have a higher burden of renal complications after demographic adjustment.

  18. Lifetime risks of kidney donation: a medical decision analysis. (United States)

    Kiberd, Bryce A; Tennankore, Karthik K


    This study estimated the potential loss of life and the lifetime cumulative risk of end-stage renal disease (ESRD) from live kidney donation. Markov medical decision analysis. USA. 40-year-old live kidney donors of both sexes and black/white race. Live donor nephrectomy. Potential remaining life years lost, quality-adjusted life years (QALYs) lost and added lifetime cumulative risk of ESRD from donation. Overall 0.532-0.884 remaining life years were lost from donating a kidney. This was equivalent to 1.20%-2.34% of remaining life years (or 0.76%-1.51% remaining QALYs). The risk was higher in male and black individuals. The study showed that 1%-5% of average-age current live kidney donors might develop ESRD as a result of nephrectomy. The added risk of ESRD resulted in a loss of only 0.126-0.344 remaining life years. Most of the loss of life was predicted to be associated with chronic kidney disease (CKD) not ESRD. Most events occurred 25 or more years after donation. Reducing the increased risk of death associated with CKD had a modest overall effect on the per cent loss of remaining life years (0.72%-1.9%) and QALYs (0.58%-1.33%). Smoking and obesity reduced life expectancy and increased overall lifetime risks of ESRD in non-donors. However the percentage loss of remaining life years from donation was not very different in those with or without these risk factors. Live kidney donation may reduce life expectancy by 0.5-1 year in most donors. The development of ESRD in donors may not be the only measure of risk as most of the predicted loss of life predates ESRD. The study identifies the potential importance of following donors and treating risk factors aggressively to prevent ESRD and to improve donor survival. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

  20. Kidney Paired Donation and the "Valuable Consideration" Problem: The Experiences of Australia, Canada, and the United States. (United States)

    Toews, Maeghan; Giancaspro, Mark; Richards, Bernadette; Ferrari, Paolo


    As organ donation rates remain unable to meet the needs of individuals waiting for transplants, it is necessary to identify reasons for this shortage and develop solutions to address it. The introduction of kidney paired donation (KPD) programs represents one such innovation that has become a valuable tool in donation systems around the world. Although KPD has been successful in increasing kidney donation and transplantation, there are lingering questions about its legality. Donation through KPD is done in exchange for-and with the expectation of-a reciprocal kidney donation and transplantation. It is this reciprocity that has caused concern about whether KPD complies with existing law. Organ donation systems around the world are almost universally structured to legally prohibit the commercial exchange of organs. Australia, Canada, and the United States have accomplished this goal by prohibiting the exchange of an organ for "valuable consideration," which is a legal term that has not historically been limited to monetary exchange. Whether or not KPD programs violate this legislative prohibition will depend on the specific legislative provision being considered, and the legal system and case law of the particular jurisdiction in question. This article compares the experiences of Australia, Canada, and the United States in determining the legality of KPD and highlights the need for legal clarity and flexibility as donation and transplantation systems continue to evolve.

  1. Nonaltruistic kidney donations in contemporary Jewish law and ethics. (United States)

    Grazi, Richard V; Wolowelsky, Joel B


    In 2000, the Consensus Statement on the Live Organ Donor reported that "direct financial compensation for an organ from a living donor remains controversial and illegal in the United States" and took note of the position of the Transplantation Society that "Organs and tissue should be given without commercial consideration or commercial profit." Christian authorities insist that organ donors must not accrue economic advantage, and "selling" organs deprives the donation of its ethical quality. The writings of major contemporary authorities of Jewish law and ethics whose halakhic positions on bioethical issues are regularly considered by Orthodox, Conservative, and Reform ethicists were reviewed. Their positions on this issue were contrasted with those of various contemporary secular and religious authorities. These Jewish authorities reject the notion that generosity and charity, rather than monetary gain and greed, must serve as the exclusive basis for donation of functioning organs. Although nonaltruistic sale of kidneys may be theoretically ethical, ultimately its ethical status in Jewish ethics and law is inextricably connected to solving a series of pragmatic programs, such as creating a system that ensures that potential vendors and donors are properly informed and not exploited. Lacking such arrangements, ethical nonaltruistic kidney donations remain but a theoretical possibility.

  2. Pre-donation cognitions of potential living organ donors: the development of the Donation Cognition Instrument in potential kidney donors. (United States)

    Wirken, Lieke; van Middendorp, Henriët; Hooghof, Christina W; Sanders, Jan-Stephan F; Dam, Ruth E; van der Pant, Karlijn A M I; Berendsen, Elsbeth C M; Wellink, Hiske; Dackus, Henricus J A; Hoitsma, Andries J; Hilbrands, Luuk B; Evers, Andrea W M


    Cognitions surrounding living organ donation, including the motivation to donate, expectations of donation and worries about donation, are relevant themes during living donor evaluation. However, there is no reliable psychometric instrument assessing all these different cognitions. This study developed and validated a questionnaire to assess pre-donation motivations, expectations and worries regarding donation, entitled the Donation Cognition Instrument (DCI). Psychometric properties of the DCI were examined using exploratory factor analysis for scale structure and associations with validated questionnaires for construct validity assessment. From seven Dutch transplantation centres, 719 potential living kidney donors were included. The DCI distinguishes cognitions about donor benefits, recipient benefits, idealistic incentives, gratitude and worries about donation (Cronbach's alpha 0.76-0.81). Scores on pre-donation cognitions differed with regard to gender, age, marital status, religion and donation type. With regard to construct validity, the DCI was moderately correlated with expectations regarding donor's personal well-being and slightly to moderately to health-related quality of life. The DCI is found to be a reliable instrument assessing cognitions surrounding living organ donation, which might add to pre-donation quality of life measures in facilitating psychosocial donor evaluation by healthcare professionals. © The Author 2017.

  3. Long-term Renal Function in Living Kidney Donors Who Had Histological Abnormalities at Donation. (United States)

    Fahmy, Lara M; Massie, Allan B; Muzaale, Abimereki D; Bagnasco, Serena M; Orandi, Babak J; Alejo, Jennifer L; Boyarsky, Brian J; Anjum, Saad K; Montgomery, Robert A; Dagher, Nabil N; Segev, Dorry L


    Recent evidence suggests that living kidney donors are at an increased risk of end-stage renal disease. However, predicting which donors will have renal dysfunction remains challenging, particularly among those with no clinical evidence of disease at the time of donation. Although renal biopsies are not routinely performed as part of the donor evaluation process, they may yield valuable information that improves the ability to predict renal function in donors. We used implantation protocol biopsies to evaluate the association between histological abnormalities in the donated kidney and postdonation renal function (estimated glomerular filtration rate, eGFR) of the remaining kidney in living kidney donors. Longitudinal analysis using mixed-effects linear regression was used to account for multiple eGFR measures per donor. Among 310 donors between 1997 and 2012, median (IQR) follow-up was 6.2 (2.5-8.7; maximum 14.0) years. In this cohort, the overall prevalence of histological abnormalities was 65.8% (19.7% abnormal glomerulosclerosis, 23.9% abnormal interstitial fibrosis and tubular atrophy (IFTA), 4.8% abnormal mesangial matrix increase, 32.0% abnormal arteriolar hyalinosis, and 32.9% abnormal vascular intimal thickening). IFTA was associated with a 5-mL/min/1.73 m decrease of postdonation eGFR after adjusting for donor age at donation, sex, race, preoperative systolic blood pressure, preoperative eGFR, and time since donation (P < 0.01). In this single-center study, among healthy individuals cleared for living donation, IFTA was associated with decreased postdonation eGFR, whereas no other subclinical histological abnormalities provided additional information.

  4. Attitude toward living kidney donation: differences between students from two Spanish universities. (United States)

    Martínez-Alarcón, L; Ramis, G; Gómez-Laguna, J; Quereda, J J; Herrero-Medrano, J M; Mrowiec, A; Mendonça, L; López-Navas, A; Ríos, A


    Due to the current deficit of organs for transplantation, living kidney related donations (LKRD) should be promoted. Veterinarians often hold decision-making positions in the public health care system, and therefore can influence public opinion about organ donation. The objective was to analyze the attitude of Spanish veterinary students toward LKRD because they may influence public opinion in the future, and to determine the factors that condition it. The study was carried out among fifth-year veterinary science students from 2 southern and southeastern Spanish universities. The students' attitude toward LKRD was assessed using a psychosocial, anonymous, self-administered questionnaire. Statistics used were χ(2) test and Student t test. Data from the southern Spain university included a response rate of 87%. The survey showed that 94% of respondents would donate a kidney to a relative who needed it. This attitude toward LKRD was more favorable in women (P attitude was not associated with any psychosocial variables. However, only 58% would accept a kidney from a relative. There are no differences between the 2 universities (P = .879). Although the attitude of veterinary students from southern and southeastern Spain toward LKRD was very favorable and there are no differences between them, only 58% of the students would accept an organ from a relative.

    The Nigerian population is an emerging group in Spain and in Europe, but their sensitization toward living kidney donation has not been studied. The aim of this work was to analyze the attitude toward related renal donation while alive among the population born in Nigeria resident in Spain. A population older than 15 years born in Nigeria and resident in Spain, stratified by age and sex, was studied with the use of the attitude questionnaire about living kidney donation, "PCID-DVR-Ríos." People were randomly selected based on stratification. African immigration support associations advised on the location of potential respondents. Completion of the questionnaire was anonymous and self-administered. Verbal consent was requested to assist in the study. Statistical methods included Student t test, χ 2 , Fisher exact test, and logistic regression analysis. A total of 179 respondents were included in the study: 70% (n = 125) were in favor of living-related kidney donation, and 30% (n = 54) remained against or undecided. This attitude was associated with different psychosocial factors: marital status (P = .001), having offspring (P = .029), risk assessment of live donation (P donation (P donation and/or transplantation (P donation (P donation and/or transplantation (odds ratio, 8.064) persisted as the main related factor.

    Access to renal replacement therapy by the increasing population of patients with end-stage kidney disease across Sub-Saharan Africa, including Nigeria, has become a major public health challenge. Although deceased kidney donation constitutes a viable source, its uptake by patients is contingent on its acceptance by health-care workers. The aim of this study is to assess the awareness and attitude to deceased kidney donation among health-care workers in Sokoto, Nigeria. A cross-sectional study was conducted among 470 staff of Usmanu Danfodiyo University Teaching Hospital, Sokoto, Nigeria (attending a 1-week seminar), selected by universal sampling. Data were collected with a set of pretested, self-administered, and semi-structured questionnaire. The mean age of the respondents was 34.1 ± 7.8 years, and most of them (77.7%) were aged donation, only about half (51.9%) were willing to accept deceased kidney donation. Furthermore, 43.4% were willing to give consent to donate deceased relative's kidney, and 26.1% were willing to carry an organ donation card. Predictors of willingness to accept deceased kidney donation were male sex, being a medical doctor or laboratory scientist and being a Moslem (Odds ratio >2, P donation is crucial to promoting its acceptance among them.

  7. Histopathologic Findings of Potential Kidney Donors With Asymptomatic Microscopic Hematuria: Impact on Donation. (United States)

    Hassan, E A; Ali, T Z; Abdulbaki, A; Ibrahim, I A; Almanae, H M; Aleid, H A


    Isolated microscopic hematuria (IMH) is not uncommon in potential kidney donors. The aim was to study the kidney biopsy findings of potential kidney donors with IMH and the impact of the histopathologic diagnoses on the decision to accept or decline such donors from kidney donation. In this retrospective study, all the potential kidney donors with IMH were identified from the medical records of patients who underwent kidney biopsies between January 2010 and December 2016. Forty-five such individuals were identified. The mean age of these potential donors was 32.6 years and 76% were male. All of them had normal blood pressure and no significant proteinuria. Seventeen (38%) biopsies showed histopathologic abnormalities; thin basement membrane disease (n = 13; 28%) was the most common cause followed by immunoglobulin (Ig)A nephropathy (n = 4; 9%). Donors with abnormal biopsy findings were excluded from donation. However, 62% of the potential donors had normal kidney biopsy findings and were accepted for kidney donation. IMH justifies extensive work-up including kidney biopsy to identify donors who may have underlying significant glomerular pathology excluding them from kidney donation. On the other hand, kidney biopsy also helps in accepting the donors if it does not show significant abnormality. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. Coercion, dissatisfaction, and social stigma: an ethnographic study of compensated living kidney donation in Iran. (United States)

    Fry-Revere, Sigrid; Chen, Deborah; Bastani, Bahar; Golestani, Simin; Agarwal, Rachana; Kugathasan, Howsikan; Le, Melissa


    This article updates the qualitative research on Iran reported in the 2012 article by Tong et al. "The experiences of commercial kidney donors: thematic synthesis of qualitative research" (Tong et al. in Transpl Int 25:1138-1149, 2012). The basic approach used in the Tong et al. article is applied to a more recent and more comprehensive study of Iranian living organ donors, providing a clearer picture of what compensated organ donation is like in Iran since the national government began regulating compensated donation. Iran is the only country in the world where kidney selling is legal, regulated, and subsidized by the national government. This article focuses on three themes: (1) coercion and other pressures to donate, (2) donor satisfaction with their donation experience, and (3) whether donors fear social stigma. We found no evidence of coercion, but 68% of the paid living organ donors interviewed felt pressure to donate due to extreme poverty or other family pressures. Even though 27% of the living kidney donors interviewed said they were satisfied with their donation experience, 74% had complaints about the donation process or its results, including some of the donors who said they were satisfied. In addition, 84% of donors indicated they feared experiencing social stigma because of their kidney donation.

    Introduction: There is a wide discrepancy between demand for and availability of donor organs for organ transplantation. There is no study on awareness about organ donation in chronic kidney disease (CKD) patients in India. Objectives: To study the awareness and beliefs towards organ donation in CKD patients on hemodialysis in western India. Patients and Methods: Authors conducted a cross sectional study among 85 CKD patients to evaluate knowledge about and attitude towards organ donation at a tertiary hospital. Results: Age of respondents ranged from 15 to 75 years. All were aware of term organ donation and cadaver donation. About 47% of people heard about organ donation through hospital or from doctor. Strikingly, radio was not the source of information to any of the respondents, despite radio being one of the most common medium of mass communication. Almost one third of patients were unaware about any legislation regarding organ donation. All respondents felt that organs should go to the needy irrespective of their religion. About 70% feel that medical colleges should make decisions about organ donation in case of unclaimed dead bodies. About 31.76% believe that there is a danger that donated organs could be misused, abused or misappropriated. Conclusion: Our study shows about 31.76% of our participants believe that there is a danger that donated organs could be misused, abused or misappropriated. There seems to be paucity of information and awareness regarding organ donation among CKD patients. Mass media, religious and political leaders may be involved to maximize awareness about organ donation.

  10. Impression management during evaluation and psychological reactions post-donation of living kidney donors. (United States)

    Hildebrand, Lee; Melchert, Timothy P; Anderson, Rebecca C


    Many healthcare providers have been concerned about the extent to which potential kidney donors use impression management or concealment of important information regarding their medical history, current functioning, or other circumstances that could affect whether they are accepted as donors. To date, however, there has been very little empirical examination of these questions. It is also not known whether donors' use of impression management pre-donation is related to their reactions and adjustment post-donation. This study surveyed 76 individuals who had donated a kidney one to six yr previously regarding their use of impression management and their concealing of information during their psychological evaluations. They were also asked about their reactions to the donation and whether they would make the same decision again. In addition, 21 of these donors participated in focus groups that explored these questions in depth. Many of the kidney donors reported that they possessed very strong motivation to donate and consequently used impression management in their interactions with medical professionals pre-donation. Very few donors, however, indicated that they concealed information during their pre-donation evaluations. The donors' psychological reactions post-donation were generally positive, and nearly all indicated that they would make the same decision again. © 2014 John Wiley & Sons A/S.

  12. Should We Formulate an Incentivized Model Facilitating Kidney Donation from Living Donors? A Focus on Turkey's Current System. (United States)

    Avci, Ercan


    Kidney transplantation is a lifesaving medical treatment. However, very high demand for kidneys with low kidney donation causes a black market that exploits patients' desperation and donors' vulnerability. The current kidney donation programs fail to produce promising results to avoid illegal and unethical kidney trafficking and commercialism. Even though the primary goal of kidney donation is to increase the number of deceased organ donations, in some countries, like Turkey, due to religious or cultural concerns, it is impossible to supply adequate deceased kidney donations. In this view, the aim of this paper is to examine kidney trafficking in the scope of Turkey's current organ donation system and propose a new model, named the Incentivized Kidney Donation Model (IKDM), to increase kidney donation from living donors. The model encompasses the following benefits offered to kidney donors; lifetime health insurance, exemptions from copayments/contribution shares, priority when receiving an organ, priority when finding a job, income tax exemptions for salaried employees, and free or discounted public utilities. This normative model has the potential to promote donors' altruistic acts as well as the solidarity and loyalty among members of a society without violating ethical values and internationally accepted principles. © 2018 John Wiley & Sons Ltd.

  13. A Case Report of Successful Kidney Donation After Brain Death Following Nicotine Intoxication. (United States)

    Räsänen, M; Helanterä, I; Kalliomäki, J; Savikko, J; Parry, M; Lempinen, M

    Nicotine intoxication is a rare cause of death and can lead to brain death after respiratory arrest and hypoxic-ischemic encephalopathy. To our knowledge, no previous reports regarding organ donation after nicotine intoxication have been described. We present a successful case of kidney donation after brain death caused by subcutaneous nicotine overdose from liquid nicotine from an e-cigarette cartridge in an attempted suicide. Both kidneys were transplanted successfully with immediate graft function, and both recipients were discharged at postoperative day 9 with normal plasma creatinine levels. Graft function has remained excellent in follow-up. This case suggests that kidneys from a donor with fatal nicotine intoxication may be successfully used for kidney transplantation in the absence of other contraindications for donation.

    The perception of living kidney donation-related financial burden affects willingness to donate and the experience of donation, yet no existing tools identify donors who are at higher risk of perceived financial burden. We sought to identify characteristics that predicted higher risk of perceived financial burden. We surveyed 51 living kidney donors (LKDs) who donated from 01/2015 to 3/2016 about socioeconomic characteristics, predonation cost concerns, and perceived financial burden. We tested associations between both self-reported and ZIP code-level characteristics and perceived burden using Fisher's exact test and bivariate modified Poisson regression. Donors who perceived donation-related financial burden were less likely to have an income above their ZIP code median (14% vs. 72%, P = .006); however, they were more likely than donors who did not perceive burden to rent their home (57% vs. 16%, P = .03), have an income donation-related cost concerns prior to donation might allow transplant centers to target financial support interventions toward potential donors at higher risk of perceiving donation-related financial burden. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  15. Interviews of living kidney donors to assess donation-related concerns and information-gathering practices. (United States)

    Ruck, Jessica M; Van Pilsum Rasmussen, Sarah E; Henderson, Macey L; Massie, Allan B; Segev, Dorry L


    Efforts are underway to improve living kidney donor (LKD) education, but current LKD concerns and information-gathering preferences have not been ascertained to inform evidence-based resource development. As a result, prior studies have found that donors desire information that is not included in current informed consent and/or educational materials. We conducted semi-structured interviews with 50 LKDs who donated at our center to assess (1) concerns about donation that they either had personally before or after donation or heard from family members or friends, (2) information that they had desired before donation, and (3) where they sought information about donation. We used thematic analysis of verbatim interview transcriptions to identify donation-related concerns. We compared the demographic characteristics of participants reporting specific concerns using Fisher's exact test. We identified 19 unique concerns that participants had or heard about living kidney donation. 20% of participants reported having had no pre-donation concerns; 38% reported no post-donation concerns. The most common concern pre-donation was future kidney failure (22%), post-donation was the recovery process (24%), and from family was endangering their family unit (16%). 44% of participants reported being less concerned than family. 26% of participants wished they had had additional information prior to donating, including practical advice for recovery (10%) and information about specific complications (14%). Caucasian participants were more likely to hear at least one concern from family (76% vs. 33%, p = 0.02). The most commonly consulted educational resources were health care providers (100%) and websites (79% of donors since 2000). 26% of participants had had contact with other donors; an additional 20% desired contact with other LKDs. Potential donors not only have personal donation-related concerns but frequently hear donation-related concerns from family members and friends

  16. Overweight young female kidney donors have low renal functional reserve post-donation. (United States)

    van Londen, Marco; Schaeffers, Anouk W M A; de Borst, Martin H; Joles, Jaap A; Navis, Gerjan; Lely, A Titia


    Maintenance of adequate renal function after living kidney donation is important for donor outcome. Overweight donors in particular may have an increased risk for end stage kidney disease (ESKD), and young female donors have an increased preeclampsia risk. Both of these risks may associate with low post-donation renal functional reserve (RFR). Because we previously found that higher BMI and lower post-donation RFR were associated, we now studied the relationship between BMI and RFR in young female donors. RFR, the rise in GFR (125I-Iothalamate clearance) during dopamine, was measured in female donors (donation. Donors who are overweight (BMI>25) and non-overweight donors were compared by t-test; the association was subsequently explored with regression analysis. We included 105 female donors (age 41 [36-44] (median[IQR])) with a BMI of 25 [22-27] kg/m2. Pre-donation GFR was 118 (17) ml/min (mean(SD)) rising to 128 (19) ml/min during dopamine; mean RFR was 10 (10) ml/min. Post-donation GFR was 76 (13) ml/min, rising to 80 (12); RFR was 4 (6) ml/min (pdonation). In overweight donors, RFR was fully lost after donation (1 ml/min vs. 10 ml/min pre-donation, pdonation, independent of confounders (St. β 0.37, p=0.02). Reduced RFR might associate with the risk of preeclampsia and ESKD in kidney donors. Prospective studies should explore whether RFR is related to preeclampsia and whether BMI reduction prior to conception is of benefit to overweight female kidney donors during and after pregnancy.

  17. HIV, HCV, HBV and syphilis rate of positive donations among blood donations in Mali: lower rates among volunteer blood donors. (United States)

    Diarra, A; Kouriba, B; Baby, M; Murphy, E; Lefrere, J-J


    Good data on background seroprevalence of major transfusion transmitted infections is lacking in Mali. We gathered data on the rate of positive donations of human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV) and syphilis among blood donations in Mali for calendar year 2007. Donations with repeatedly reactive results on screening enzyme immunoassay (EIA) were considered to be seropositive. Rate of positive donations per blood unit collected was 2.6% for HIV, 3.3% for HCV, 13.9% for hepatitis B surface antigen (HBsAg) and 0.3% for syphilis. For HIV, HBsAg and syphilis, rate of positive donations was significantly (pdonations from replacement donors than those from volunteer donors, while HCV rate of positive donations was similar in the two groups. Rate of positive donations was also significantly (p<0.0001) lower in blood units from regular than from first-time donors. These data reinforce WHO recommendations for increasing the number of regular, volunteer blood donors in Africa.

  18. Causes and timing of end-stage renal disease after living kidney donation. (United States)

    Matas, Arthur J; Berglund, Danielle M; Vock, David M; Ibrahim, Hassan N


    End-stage renal disease (ESRD) is a risk after kidney donation. We sought, in a large cohort of kidney donors, to determine the causes of donor ESRD, the interval from donation to ESRD, the role of the donor/recipient relationship, and the trajectory of the estimated GFR (eGFR) from donation to ESRD. From 1/1/1963 thru 12/31/2015, 4030 individuals underwent living donor nephrectomy at our center, as well as ascertainment of ESRD status. Of these, 39 developed ESRD (mean age ± standard deviation [SD] at ESRD, 62.4 ± 14.1 years; mean interval between donation and ESRD, 27.1 ± 9.8 years). Donors developing ESRD were more likely to be male, as well as smokers, and younger at donation, and to have donated to a first-degree relative. Of donors with a known cause of ESRD (n = 25), 48% was due to diabetes and/or hypertension; only 2 from a disease that would have affected 1 kidney (cancer). Of those 25 with an ascertainable ESRD cause, 4 shared a similar etiology of ESRD with their recipient. Almost universally, thechange of eGFR over time was stable, until new-onset disease (kidney or systemic). Knowledge of factors contributing to ESRD after living kidney donation can improve donor selection and counseling, as well as long-term postdonation care. © 2018 The American Society of Transplantation and the American Society of Transplant Surgeons.

    The factors underlying the decline in living kidney donation in the United States since 2005 must be understood to inform strategies to ensure access to this option for future patients. Population-based estimates provide a better assessment of donation activity than do trends in the number of living donor transplants. Using data from the Scientific Registry of Transplant Recipients and the United States Census, we determined longitudinal changes in living kidney donation between 2005 and 2015, focusing on the effect of sex and income. We used multilevel Poisson models to adjust for differences in age, race, the incidence of ESRD, and geographic factors (including population density, urbanization, and daily commuting). During the study period, the unadjusted rate of donation was 30.1 and 19.3 per million population in women and men, respectively, and the adjusted incidence of donation was 44% higher in women (incidence rate ratio [IRR], 1.44; 95% confidence interval [95% CI], 1.39 to 1.49). The incidence of donation was stable in women (IRR, 0.95; 95% CI, 0.84 to 1.07) but declined in men (IRR, 0.75; 95% CI, 0.68 to 0.83). Income was associated with longitudinal changes in donation in both sexes, yet donation was stable in the highest two population income quartiles in women but only in the highest income quartile in men. In both sexes, living related donations declined, irrespective of income. In conclusion, living donation declined in men but remained stable in women between 2005 and 2015, and income appeared to have a greater effect on living donation in men.

  1. The Body as Gift, Commodity, or Something in Between: Ethical Implications of Advanced Kidney Donation. (United States)

    Koplin, Julian J


    An innovative program recently initiated at the University of California, Los Angeles (UCLA) Medical Center allows people to donate a kidney in exchange for a voucher that a loved one can redeem for a kidney if and when needed. As a relatively new practice, the ethical implications of advanced kidney donation have not yet been widely discussed. This paper reflects on some of the bioethical issues at stake in this new donation program, as well as some broader philosophical issues related to the meaning and moral salience of commodification. I first consider whether the literature on commercial markets in organs--a longstanding topic of bioethical debate--can meaningfully inform ethical analysis of kidney voucher programs. Specifically, I consider whether and to what extent common objections to the exchange of kidneys for cash also apply to the exchange of kidneys for "kidney vouchers." Second, I argue that the contrast between the ethical issues raised by these two practices highlights the need to understand commodification as existing on a continuum, with different degrees of commodification giving rise to different ethical issues. Doing so can help sharpen our understanding of commodification as a moral concept, as well as its relevance to broader debates about the moral limits of markets. © The Author 2017.

  2. Financial Burden Associated with Time to Return to Work After Living Kidney Donation. (United States)

    Larson, Dawn B; Wiseman, Jennifer F; Vock, David; Bergund, Danielle M; Roman, Ashley; Ibrahim, Hassan Nimer; Matas, Arthur J


    Many living kidney donors undertake a significant financial burden in order to donate. We studied the association between time to return to work and reported financial burden. Kidney donors, who donated from 2/2005 - through 12/2015 (n=1012) were surveyed 6 months postdonation, and asked about occupation; time to return to work; and financial burden (on a 10-point Likert scale). Of 856 donors working for pay, 629 (73%) responded. After adjusting for donor characteristics, increased length of time to return to work was a significant predictor of financial burden (pfinancial burden for each week away from work (p=0.003). Older age at donation and nondirected (vs directed) donation were associated with significantly decreased financial burden. These observations provide additional information to better inform donor candidates, and further emphasize the need to develop policies so that living kidney donation can be financially neutral.

  4. Donors and Recipients of Living Kidney Donation: A Qualitative Metasummary of Their Experiences

    Directory of Open Access Journals (Sweden)

    Deborah Ummel


    Full Text Available With the notable growth in the qualitative investigation of living kidney donation, there is value in aggregating results from this body of research to learn from accumulated experience. The present paper aims to draw a complete portrait of living donors' and recipients' experience of donation by metasummarizing published studies. We found that donors' experience, particularly the decision-making process, has been more extensively studied than the recipients' perspective. Donors differ in their initial level of motivation to donate but on the whole report positive experiences and personal benefits. They also identify difficult periods and the need for additional resources. Recipients report an often positive but more ambivalent reaction to donation. In terms of relational issues between dyads, while the topic remains understudied, the donor-recipient relationship and gift reciprocity have received the most attention. Results are discussed in terms of their implications for future practice and research.

  5. Is donating a kidney to a friend bad for your marriage? (United States)

    Serur, David; Charlton, Marian; Bretzlaff, Gretchen; Sinacore, Joseph; Christos, Paul; Gordon-Elliott, Janna


    Studies have shown that kidney donation to a spouse has a positive impact on marriage. This study was done to evaluate the impact on marriage when donation occurs to someone other than the spouse. Two groups of donors from our centre who donated around the same period were studied: donation to a spouse (spouse donor (SD)) or to someone other than the spouse (non-spouse donor (ND)). A survey, the Revised Dyadic Adjustment Scale, was used to evaluate the effect of donation on the marriage. This tool consists of 14 questions that measure how satisfying and stable the relationship is. The results showed equal or better marriage scores in the ND group compared with the SD group. The NDs scored higher on two questions, one regarding agreement or disagreement on career choices (P = 0.05) and the other regarding the frequency of having stimulating exchanges of ideas with one's spouse (P = 0.02). With the highest possible total score of 69, NDs scored 53.4 and SDs scored 47.7 (P = 0.16). Scores of 47 and below indicate marital distress. In one final additional question, 97% of NDs reported 'no change or good effect' on the marriage, similar to 91% for SDs (P = 0.46). This is the first study to evaluate the effect of kidney donation on the state of marriage when the spouse is not the recipient. It appears that marriage is not impacted negatively when kidney donation occurs to someone other than the spouse. © 2015 Asian Pacific Society of Nephrology.

    Full Text Available There is a dire need to evaluate new strategies to bridge the wide kidney demand-supply gap. The current study examined the attitude of medical professionals regarding controversial issues pertaining to transplantation. A questionnaire, presenting controversial issues related to kidney transplantation, in an agree-disagree format with supporting reasons, was employed. The research was exploratory. Data were analyzed quantitatively and qualitatively. The sample comprised 140 doctors from Mumbai (mean = 38.1 years, standard deviation = 17.95; Males = 44.3%, Females = 55.7%. Whereas 47.1% of the participants felt that live donors should be given incentives for kidney donation, others (52.9% disagreed, fearing commercialization and illegal activities. The eligibility of patients with HIV/hepatitis for a transplant was denied by 52.9% because of poor outcomes, with the others (47.1% maintaining that these individuals too had a right to live. A substantial majority (90.7% of the participants maintained that organ donors should be given priority in the event of a future need for an organ because their previous humane act should be rewarded (47.1%. Most of the participants (91.4% felt that individuals from the higher socioeconomic strata should not receive preference for kidney transplantation. A majority (77.1% of them were also against kidney selling getting legalized. Compulsory possession of a donor card elicited mixed responses, with some accepting (56.4%, but others rejecting (43.6% this idea as donation was perceived to be a voluntary act (33.6%. While compulsory kidney donation found favor with 44.3%, it found disfavor with others (55.7%.

  7. Use and Outcomes of Kidneys from Donation after Circulatory Death Donors in the United States. (United States)

    Gill, John; Rose, Caren; Lesage, Julie; Joffres, Yayuk; Gill, Jagbir; O'Connor, Kevin


    Donation after circulatory death (DCD) donors are an important source of kidneys for transplantation, but DCD donor transplantation is less common in the United States than in other countries. In this study of national data obtained between 2008 and 2015, recovery of DCD kidneys varied substantially among the country's 58 donor service areas, and 25% of DCD kidneys were recovered in only four donor service areas. Overall, 20% of recovered DCD kidneys were discarded, varying from 3% to 33% among donor service areas. Compared with kidneys from neurologically brain dead (NBD) donors, DCD kidneys had a higher adjusted odds ratio of discard that varied from 1.25 (95% confidence interval [95% CI], 1.16 to 1.34) in kidneys with total donor warm ischemic time (WIT) of 10-26 minutes to 2.67 (95% CI, 2.34 to 3.04) in kidneys with total donor WIT >48 minutes. Among the 12,831 DCD kidneys transplanted, kidneys with WIT≤48 minutes had survival similar to that of NBD kidneys. DCD kidneys with WIT>48 minutes had a higher risk of allograft failure (hazard ratio, 1.23; 95% CI, 1.07 to 1.41), but this risk was limited to kidneys with cold ischemia time (CIT) >12 hours. We conclude that donor service area-level variation in the recovery and discard of DCD kidneys is large. Additional national data collection is needed to understand the potential to increase DCD donor transplantation in the United States. Strategies to minimize cold ischemic injury may safely allow increased use of DCD kidneys with WIT>48 minutes. Copyright © 2017 by the American Society of Nephrology.

  8. The Ethics of Promoting Living Kidney Donation Using Nonargumentative Influence: Applications, Concerns, and Future Directions. (United States)

    Allen, M B; Reese, P P


    Recommendations from the 2014 Consensus Conference on Best Practices in Living Kidney Donation reflect increasing attention to overcoming barriers to donation as a means of expanding access to living donor kidney transplantation. "High priority" initiatives include empowering transplant candidates and their loved ones in their search for a living kidney donor. Transplant programs are assuming an unprecedented role as facilitators of patients' solicitation for donors, and nonprofits are promoting living kidney donation (LKD) in the community. New strategies to promote LKD incorporate "nonargumentative" forms of influence (i.e. approaches to shaping behavior that do not attempt to persuade through reason) such as appeals to emotion, messenger effects and social norms. These approaches have raised ethical concerns in other settings but have received little attention in the transplantation literature despite their increasing relevance. Previous work on using nonargumentative influence to shape patient behavior has highlighted implications for (1) the relationship between influencer and influenced and (2) patient autonomy. We argue that using nonargumentative influence to promote LKD is a promising strategy that can be compatible with ethical standards. We also outline potential concerns and solutions to be implemented in practice. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  9. Banking on Living Kidney Donors-A New Way to Facilitate Donation without Compromising on Ethical Values. (United States)

    Martin, Dominique E; Danovitch, Gabriel M


    Public surveys conducted in many countries report widespread willingness of individuals to donate a kidney while alive to a family member or close friend, yet thousands suffer and many die each year while waiting for a kidney transplant. Advocates of financial incentive programs or "regulated markets" in kidneys present the problem of the kidney shortage as one of insufficient public motivation to donate, arguing that incentives will increase the number of donors. Others believe the solutions lie-at least in part-in facilitating so-called "altruistic donation;" harnessing the willingness of relatives and friends to donate by addressing the many barriers which serve as disincentives to living donation. Strategies designed to minimize financial barriers to donation and the use of paired kidney exchange programs are increasingly enabling donation, and now, an innovative program designed to address what has been termed "chronologically incompatible donation" is being piloted at the University of California, Los Angeles, and elsewhere in the United States. In this program, a person whose kidney is not currently required for transplantation in a specific recipient may instead donate to the paired exchange program; in return, a commitment is made to the specified recipient that priority access for a living-donor transplant in a paired exchange program will be offered when or if the need arises in the future. We address here potential ethical concerns related to this form of organ "banking" from living donors, and argue that it offers significant benefits without undermining the well-established ethical principles and values currently underpinning living donation programs. © The Author 2017.

  10. Koplin, Titmuss and the social tail that wags the dog: Commentary on Koplin, "From blood donation to kidney sales". (United States)

    Shearmur, Jeremy


    This paper is a commentary on Koplin's "From Blood Donation to Kidney Sales". While appreciative of his paper, it argues that an argument from social solidarity to a Titmussian donor system is problematic. It reviews weaknesses in Titmuss, discusses problems about Titmussian blood donation as a vehicle for solidarity, and explores problems about extending a Titmussian approach to organs.

  11. Risk Taking and Decision Making in Kidney Paired Donation: A Qualitative Study by Semistructured Interviews. (United States)

    Baines, L S; Dulku, H; Jindal, R M; Papalois, V


    Despite excellent outcomes of kidney paired donation (KPD), little is known about how a patient's frame (apply cognitive bias) or weight (attribute value) and concerns relating to risk, justice, and equity affect his or her decision-making process. A pilot study consisting of 3 KPD transplant recipients and 3 KPD kidney donors in the last year was conducted to identify and explore themes in decision making and risk taking. The pilot study was followed by the main study comprised of 20 recipients who had already undergone KPD transplantation and 20 donors who had undergone donor nephrectomy. We conducted semistructured interviews in this cohort and analyzed the data thematically. Each donor-recipient pair was interviewed together to facilitate dyadic conversation and provide deeper insight into the decision-making process leading to transplant and donation. Common themes to both recipient and donor decision making included quality of life; characteristics of the unknown donor and post-transplant expectations. Recipient-specific themes included failure to reach life span milestones, experiences of fellow patients, and altruistic desire to expand the donor pool. Donor-specific themes included balancing existing life commitments with the recipient's need for a kidney, equity and mental accounting in kidney exchange (comparable quality of the kidney received versus the kidney donated), and logistical justice for the recipient. Donors and recipients frame and weight the concepts of risk, justice, and equity differently. This may have direct implications to facilitating patient-centered communication and engagement in KPD pairs. Copyright © 2018 Elsevier Inc. All rights reserved.

  12. The science of Stewardship: due diligence for kidney donors and kidney function in living kidney donation--evaluation, determinants, and implications for outcomes. (United States)

    Poggio, Emilio D; Braun, William E; Davis, Connie


    Living kidney donor transplantation is now a common treatment for ESRD because it provides excellent outcomes to transplant recipients and is considered a safe procedure for prospective donors. The short- and long-term safety of prospective donors is paramount to the continued success of this procedure. Whereas the initial experiences with living kidney donors mostly included the healthiest, the increase in the need for organs and the changing demographic characteristics of the general population have subtly reshaped the suitability for donation. Kidney function assessment is a critical component of the evaluation of prospective donors; therefore, special emphasis is usually placed on this aspect of the evaluation. At the same time, consideration of kidney function after donation is important because it assists with the determination of renal health in donors. This review summarizes the process of predonation kidney function assessment, determinants of pre- and postdonation renal function, and, importantly, the potential implications of kidney function to the long-term outcomes of kidney donors.

  13. Sequential improvements in organ procurement increase the organ donation rate. (United States)

    Billeter, Adrian T; Sklare, Seth; Franklin, Glen A; Wright, Jerry; Morgan, Gary; O'Flynn, Paul E; Polk, Hiram C


    Organ demand exceeds availability of transplantable organs. Organ procurement continues to suffer from failures to identify potential donors, inability to obtain consent for donation, as well as failures to retrieve certain organs as donor demographics change. The purpose of this article is to propose how sequentially introduced measures can increase organ donation rates as well as improve organ procurement. We analysed the effect of stepwise improvements in the organ procurement process patients in a university-based surgical intensive care unit over a 20-year period. We related newly introduced measures in the organ retrieval process with changes in donation rates. We specifically targeted these three main steps in the donation process: donor identification, conversion of potential donors to actual donors, and organ protection during the procurement process. Finally, we assessed the effect of the same measures on organ procurement after introduction in other hospitals of the same organ procurement region. Introduction of quality improvement steps increased all of the observed parameters. The number of organ donors was stabilised due to a better identification of potential donors, a major increase in conversion from potential to actual donors, and an increase in extended criteria donor. Improvements in organ protection led to higher rates of organs transplanted per donor and increased recovery of lungs and hearts despite increasing donor age. The same measures were introduced successfully in other hospitals in our organ procurement region. Sequential improvements in organ procurement can increase the yield of retrieved organs. The same measures can be applied to other hospitals and lead to comparable improvements in organ donation. Published by Elsevier Ltd.

  14. Increasing access to kidney transplantation for sensitized recipient through three-way kidney paired donation with desensitization: The first Indian report (United States)

    Kute, Vivek B; Patel, Himanshu V; Shah, Pankaj R; Modi, Pranjal R; Shah, Veena R; Rizvi, Sayyed J; Pal, Bipin C; Modi, Manisha P; Shah, Priya S; Varyani, Umesh T; Wakhare, Pavan S; Shinde, Saiprasad G; Ghodela, Viajay A; Patel, Minaxi H; Trivedi, Varsha B; Trivedi, Hargovind L


    The combination of kidney paired donation (KPD) with desensitization represents a promising method of increasing the rate of living donor kidney transplantation (LDKT) in immunologically challenging patients. Patients who are difficult to match and desensitize due to strong donor specific antibody are may be transplanted by a combination of desensitization and KPD protocol with more immunologically favorable donor. We present our experience of combination of desensitization protocol with three-way KPD which contributed to successful LDKT in highly sensitized end stage renal disease patient. All recipients were discharged with normal and stable allograft function at 24 mo follow up. We believe that this is first report from India where three-way KPD exchange was performed with the combination of KPD and desensitization. The combination of desensitization protocol with KPD improves access and outcomes of LDKT. PMID:27803919

  15. Live kidney donation: are concerns about long-term safety justified?—A methodological review

    International Nuclear Information System (INIS)

    Janki, Shiromani; Steyerberg, Ewout W.; Hofman, Albert; IJzermans, Jan N. M.


    Live kidney donors are exhaustively screened pre-donation, creating a cohort inherently healthier at baseline than the general population. In recent years, three renowned research groups reported unfavourable outcomes for live kidney donors post-donation that contradicted their previous studies. Here, we compared the study design and analysis of the most recent and previous studies to determine whether the different outcomes were due to methodological design or reflect a real potential disadvantage for living kidney donors. All six studies on long-term risk after live kidney donation were thoroughly screened for the selection of study population, controls, data quality, and statistical analysis. Our detailed review of the methodology revealed key differences with respect to selection of donors and compared non-donors, data quality, follow-up duration, and statistical analysis. In all studies, the comparison group of non-donors was healthier than the donors due to more extensive exclusion criteria for non-donors. Five of the studies used both restriction and matching to address potential confounding. Different matching strategies and statistical analyses were used in the more recent studies compared to previous studies and follow-up was longer. Recently published papers still face bias. Strong points compared to initial analyses are the extended follow-up time, large sample sizes and better analysis, hence increasing the reliability to estimate potential risks for living kidney donors on the long-term. Future studies should focus on equal selection criteria for donors and non-donors, and in the analysis, follow-up duration, matched sets, and low absolute risks among donors should be accounted for when choosing the statistical technique.

  16. An interactive, bilingual, culturally targeted website about living kidney donation and transplantation for hispanics: development and formative evaluation. (United States)

    Gordon, Elisa J; Feinglass, Joe; Carney, Paula; Ramirez, Daney; Olivero, Maria; O'Connor, Kate; MacLean, Jessica; Brucker, James; Caicedo, Juan Carlos


    As the kidney shortage continues to grow, patients on the waitlist are increasingly turning to live kidney donors for transplantation. Despite having a disproportionately higher prevalence of end-stage kidney disease (ESKD), fewer waitlisted Hispanic patients received living donor kidney transplants (LDKTs) than non-Hispanic whites in 2014. Although lack of knowledge has been identified as a barrier to living kidney donation (LKD) among Hispanics, little is known about information needs, and few bilingual educational resources provide transplant-related information addressing Hispanics' specific concerns. This paper describes the process of developing a bilingual website targeted to the Hispanic community. The website was designed to increase knowledge about LKD among Hispanic patients with ESKD, their families, and the public, and was inspired by educational sessions targeted to Hispanic transplant patients provided by Northwestern University's Hispanic Kidney Transplant Program. Northwestern faculty partnered with the National Kidney Foundation of Illinois for expertise in ESKD and Hispanic community partners across the Chicago area. We established a Community Advisory Board (CAB) of 10 Chicago-area Hispanic community leaders to provide insight into cultural concerns and community and patients' needs. Website content development was informed by 9 focus groups with 76 adult Hispanic kidney transplant recipients, living kidney donors, dialysis patients, and the general Hispanic public. The website development effort was guided by community input on images, telenovela scripts, and messages. After initial development, formal usability testing was conducted with 18 adult Hispanic kidney transplant recipients, dialysis patients, and living kidney donors to identify ways to improve navigability, design, content, comprehension, and cultural sensitivity. Usability testing revealed consistently high ratings as "easy to navigate", "informative", and "culturally appropriate

  17. Differences in Attitudes Toward Living Kidney Donation Among Dominican Immigrants Living in Spain and the United States. (United States)

    Ríos, A; López-Navas, A I; Sánchez, Á; Flores-Medina, J; Ayala, M A; Garrido, G; Sebastián, M J; Martínez-Alarcón, L; Ramis, G; Hernández, A M; Ramírez, P; Parrilla, P


    The Dominican population has a double-emigration pathway: one is to the USA, by proximity, and the other is to Spain, by sociocultural identification. Our aim was to determine attitudes toward living organ donation among Dominicans residing in Florida (USA) and Spain. All study participants were at least 15 years old and living in either Florida (USA) or Spain, and stratified by gender and age. A questionnaire on attitudes toward living kidney donation ("PCID-LKD Ríos") was used. The support of immigrant associations in Florida and Spain was required to advise on survey locations. Data obtained were anonymized and self-administered. The study questionnaire was completed by 123 Dominicans, 68% of whom were in favor of living related kidney donation. There were differences (P = .004) according to the country of residence. Eighty-one percent of Spain's Dominican residents were in favor, compared with 56% of Florida's residents. Factors associated with attitude toward donation were level of education (P donation (P = .006), attitude toward cadaveric organ donation (P donation (P = .046). Attitudes toward living kidney donation among immigrant Dominicans varies between Spain and the USA, with the former showing a more positive view. Copyright © 2017 Elsevier Inc. All rights reserved.

    Some living kidney donors (LKDs) incur costs associated with donation, although these costs are not well characterized in the United States. We collected cost data in the 12 mo following donation from 182 LKDs participating in the multicenter prospective Kidney Donor Outcomes Cohort (KDOC) Study. Most LKDs (n = 167, 92%) had one direct cost or more following donation, including ground transportation (86%), health care (41%), meals (53%), medications (36%), lodging (23%), and air transportation (12%). LKDs missed 33 072 total work hours, 40% of which were unpaid and led to $302 175 in lost wages (mean $1660). Caregivers lost $68 655 in wages (mean $377). Although some donors received financial assistance, 89% had a net financial loss in the 12-mo period, with one-third (33%) reporting a loss exceeding $2500. Financial burden was higher for those with greater travel distance to the transplant center (Spearman's ρ = 0.26, p neutrality for LKDs must be an immediate priority for the transplant community, governmental agencies, insurance companies, nonprofit organizations, and society at large. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  20. An empirical investigation of physicians' attitudes toward intrasibling kidney donation by minor twins. (United States)

    Joseph, Josh W; Thistlethwaite, J Richard; Josephson, Michelle A; Ross, Lainie Friedman


    A United States consensus group on the live donor concluded that minors (international guidelines reject this position. Recent United Network of Organ Sharing data show that minors serve as living donors, albeit infrequently. We examined the attitudes of US physicians toward minors as living donors. Four hundred members of the American Society of Transplantation and 160 physicians from the American Academy of Pediatrics Section of Nephrology or Bioethics were surveyed. The physicians were asked whether minors should be permitted to serve as living donors and how their opinion would change depending on the twins' zygosity, age, and increased waitlist time. One hundred seventy of 436 eligible participants (39%) returned surveys. Thirty-two and 39% of respondents would permit a kidney donation between 15-year-old fraternal and identical twins, respectively (P=NS). If the wait time increased from 1 to 6 years, willingness increased to 39% and 45%, respectively (P=NS). Pediatric bioethicists were the most reluctant to prohibit minors as living donors. Approximately one-third of US physicians would permit children to serve as donors. Lengthening the wait time is associated with a trend toward greater willingness to permit minor donations. Current policies that give preferential status for a deceased donor organ to minors may help minimize donations by their minor siblings. Nontransplant physicians need education about donor risks to ensure that donations are in the best interest of pediatric donors and recipients.

  1. Cancer rates after kidney transplantation

    DEFF Research Database (Denmark)

    Sodemann, Ulrik; Bistrup, Claus; Marckmann, Peter


    Previous studies demonstrated a 3-5-fold increased cancer risk in kidney allograft recipients compared with the general population. Our aim was to estimate cancer frequencies among kidney allograft recipients who were transplanted in 1997-2000 and who were immunosuppressed according to a more...

  2. The outcomes of simultaneous liver and kidney transplantation using donation after cardiac death organs. (United States)

    Alhamad, Tarek; Spatz, Christin; Uemura, Tadahiro; Lehman, Eric; Farooq, Umar


    There has been a remarkable increase in simultaneous liver and kidney transplantations (SLK). As organ demand has increased, so has the use of donation after cardiac death (DCD). However, little is known about the outcomes of DCD in SLK. We performed a retrospective analysis using the United Network for Organ Sharing database to compare the outcomes of DCD SLK to donation after brain death (DBD) and determine the impact of donor and recipient factors on allograft and patient survival. Between 2002 and 2011, a total of 3,026 subjects received SLK from DBD and 98 from DCD. Kidney, liver, and patient survival from DCD donors were inferior to DBD at 1, 3, and 5 years (P=0.0056, P=0.0035, and P=0.0205, respectively). With the use of the Cox model, DCD was a significant risk factor for kidney and liver allograft failure and patient mortality. Recipient factors that were associated with worse allograft and patient outcomes included black race, diabetes, being on a ventilator, hospitalization, delayed graft function, hepatocellular carcinoma, and intensive care unit stay. Older age of the donor was also associated with worse outcomes. Despite the decreased allograft and patient survival compared with DBD, DCD SLK provides an acceptable option for SLK, with a survival probability of more than 50% at 5 years.

  3. Presence of Cytotoxic Extracellular Histones in Machine Perfusate of Donation After Circulatory Death Kidneys. (United States)

    van Smaalen, Tim C; Beurskens, Daniëlle M H; Hoogland, E R Pieter; Winkens, Bjorn; Christiaans, Maarten H L; Reutelingsperger, Chris P; van Heurn, L W Ernest; Nicolaes, Gerry A F


    Extracellular histones are cytotoxic molecules that are related to cell stress and death. They have been shown to play a crucial role in multiple pathophysiologic processes like sepsis, inflammation, vascular dysfunction, and thrombosis. Their role in organ donation and graft function and survival is still unknown. The aim of this study was to assess whether an association exists between the presence of extracellular histones in machine perfusates and deceased donor kidney viability. Machine perfusates of 390 donations after circulatory death kidneys were analyzed for histone concentration, and corresponding graft function and survival were assessed. Extracellular histone concentrations were significantly higher in perfusates of kidneys with posttransplant graft dysfunction (primary nonfunction and delayed graft function) and were an independent risk factor for delayed graft function (odds ratio, 2.152; 95% confidence interval [95% CI], 1.199-3.863) and 1 year graft failure (hazard ratio, 1.386; 95% CI, 1.037-1.853), but not for primary nonfunction (odds ratio, 1.342; 95% CI, 0.900-2.002). One year graft survival was 12% higher in the group with low histone concentrations (P = 0.008) as compared with the group that contained higher histone concentrations. This study warrants future studies to probe for a possible role of cytotoxic extracellular histones in organ viability and suggests that quantitation of extracellular histones might contribute to assessment of posttransplant graft function and survival.

  4. Effect of donor body mass index on the outcome of donation after cardiac death kidneys: how big is too big? (United States)

    Jin, L X; Pitt, S C; Doyle, M B; Klein, C; Shenoy, S; Lowell, J A; Chapman, W C; Wellen, J R


    Morbid obesity (MO) has become an epidemic in the United Sates and is associated with adverse effects on health. The purpose of this study was to examine the effects of MO on the short-term outcomes of kidneys transplanted from donation after cardiac death (DCD) donors. Using a prospectively collected database, we reviewed 467 kidney transplantations performed at a single center between January 2008 and June 2011 to identify 67 recipients who received transplants from 40 DCD donors. The outcomes of 14 MO DCD donor kidneys were compared with 53 non-MO DCD grafts. MO was defined as a body mass index ≥ 35. Mean patient follow-up was 16 months. The MO and non-MO DCD donor groups were similar with respect to donor and recipient age, gender, race, cause of death and renal disease, time from withdrawal of life support to organ perfusion, mean human leukocyte antigen (HLA) mismatch, and overall recipient survival. Organs from MO DCD donors also had comparable rates of delayed graft function (21.4% vs 20.0%; P = not significant [NS]). At 1 year post-transplantation, a small but statistically insignificant difference was observed in the graft survival rates of MO and non-MO donors (87% vs. 96%; P = NS). One MO kidney had primary nonfunction. These data demonstrate that kidneys procured from MO DCD donors have equivalent short-term outcomes compared with non-MO grafts and should continue to be used. Further investigation is needed to examine the effect of MO on long-term renal allograft survival. Copyright © 2014 Elsevier Inc. All rights reserved.

  5. The Canadian kidney paired donation program: a national program to increase living donor transplantation. (United States)

    Cole, Edward H; Nickerson, Peter; Campbell, Patricia; Yetzer, Kathy; Lahaie, Nick; Zaltzman, Jeffery; Gill, John S


    Establishment of a national kidney paired donation (KPD) program represents a unique achievement in Canada's provincially organized health care system. Key factors enabling program implementation included consultation with international experts, formation of a unique organization with a mandate to facilitate interprovincial collaboration, and the volunteer efforts of members of the Canadian transplant community to overcome a variety of logistical barriers. As of December 2013, the program had facilitated 240 transplantations including 10% with Calculated panel reactive antibody (cPRA) ≥97%. Unique features of the Canadian KPD program include participation of n = 55 nondirected donors, performance of only donor specific antibody negative transplants, the requirement for donor travel, and nonuse of bridge donors. The national KPD program has helped maintain the volume of living kidney donor transplants in Canada over the past 5 years and serves as a model of inter-provincial collaboration to improve the delivery of health care to Canadians.

  6. Optimal Decisions for Organ Exchanges in a Kidney Paired Donation Program. (United States)

    Li, Yijiang; Song, Peter X-K; Zhou, Yan; Leichtman, Alan B; Rees, Michael A; Kalbfleisch, John D


    The traditional concept of barter exchange in economics has been extended in the modern era to the area of living-donor kidney transplantation, where one incompatible donor-candidate pair is matched to another pair with a complementary incompatibility, such that the donor from one pair gives an organ to a compatible candidate in the other pair and vice versa. Kidney paired donation (KPD) programs provide a unique and important platform for living incompatible donor-candidate pairs to exchange organs in order to achieve mutual benefit. In this paper, we propose novel organ allocation strategies to arrange kidney exchanges under uncertainties with advantages, including (i) allowance for a general utility-based evaluation of potential kidney transplants and an explicit consideration of stochastic features inherent in a KPD program; and (ii) exploitation of possible alternative exchanges when the originally planned allocation cannot be fully executed. This allocation strategy is implemented using an integer programming (IP) formulation, and its implication is assessed via a data-based simulation system by tracking an evolving KPD program over a series of match runs. Extensive simulation studies are provided to illustrate our proposed approach.

  7. Organ Donation in Switzerland - An Analysis of Factors Associated with Consent Rate (United States)

    Keel, Isabelle; Immer, Franz F.; Jüni, Peter


    Background and Aim Switzerland has a low post mortem organ donation rate. Here we examine variables that are associated with the consent of the deceased’s next of kin (NOK) for organ donation, which is a prerequisite for donation in Switzerland. Methods and Analysis During one year, we registered information from NOK of all deceased patients in Swiss intensive care units, who were approached for consent to organ donation. We collected data on patient demographics, characteristics of NOK, factors related to the request process and to the clinical setting. We analyzed the association of collected predictors with consent rate using univariable logistic regression models; predictors with p-values donation, and respecting personal values and cultural differences, could be of importance for increasing donation rates. Additional measures are needed to address the pronounced differences in consent rates between language regions. PMID:25208215

  8. Successful three-way kidney paired donation with cross-country live donor allograft transport. (United States)

    Montgomery, R A; Katznelson, S; Bry, W I; Zachary, A A; Houp, J; Hiller, J M; Shridharani, S; John, D; Singer, A L; Segev, D L


    Providing transplantation opportunities for patients with incompatible live donors through kidney paired donation (KPD) is seen as one of the important strategies for easing the crisis in organ availability. It has been estimated that an additional 1000-2000 transplants per year could be accomplished if a national KPD program were implemented in the United States. While most of these transplants could be arranged within the participants' local or regional area, patients with hard-to-match blood types or broad HLA sensitization would benefit from matching across larger geographic areas. In this case, either patients or organs would need to travel in order to obtain maximum benefit from a national program. In this study, we describe how a triple KPD enabled a highly sensitized patient (PRA 96%) to receive a well-matched kidney from a live donor on the opposite coast. The kidney was removed in San Francisco and transported to Baltimore where it was reperfused 8 h later. The patient had prompt function and 1 year later has a serum creatinine of 1.1 mg/dl. This case provides a blueprint for solving some of the complexities that are inherent in the implementation of a national KPD program in a large country like the United States.

  9. Limiting financial disincentives in live organ donation: a rational solution to the kidney shortage. (United States)

    Gaston, R S; Danovitch, G M; Epstein, R A; Kahn, J P; Matas, A J; Schnitzler, M A


    Availability of kidney transplantation is limited by an inadequate supply of organs, with no apparent remedy on the immediate horizon and increasing reliance on living donors (LDs). While some have advocated financial remuneration to stimulate donation, the National Organ Transplant Act (NOTA) of 1984 expressly forbids the offer of 'valuable consideration.' However, recent developments indicate some fluidity in the definition of valuable consideration while evolving international standards highlight deficiencies (particularly regarding long-term care and follow-up) in the current American system. Recognizing that substantial financial and physical disincentives exist for LDs, we propose a policy change that offers the potential to enhance organ availability as well as address concerns regarding long-term care. Donors assume much greater risk than is widely acknowledged, risk that can be approximated for the purpose of determining appropriate compensation. Our proposal offsets donor risk via a package of specific benefits (life insurance, health insurance and a small amount of cash) to minimize hazard and ensure donor interests are protected after as well as before nephrectomy. It will fund medical follow-up and enable data collection so that long-term risk can be accurately assessed. The proposal should be cost effective with only a small increase in the number of LDs, and the net benefit will become greater if removal of disincentives stimulates even further growth. As importantly, by directly linking compensation to risk, we believe it preserves the essence of kidney donation as a gift, consistent with NOTA and implementable in the United States without altering current legal statutes.

  10. Long-term risks of kidney living donation: review and position paper by the ERA-EDTA DESCARTES working group. (United States)

    Maggiore, Umberto; Budde, Klemens; Heemann, Uwe; Hilbrands, Luuk; Oberbauer, Rainer; Oniscu, Gabriel C; Pascual, Julio; Schwartz Sorensen, Soren; Viklicky, Ondrej; Abramowicz, Daniel


    Two recent matched cohort studies from the USA and Norway published in 2014 have raised some concerns related to the long-term safety of kidney living donation. Further studies on the long-term risks of living donation have since been published. In this position paper, Developing Education Science and Care for Renal Transplantation in European States (DESCARTES) board members critically review the literature in an effort to summarize the current knowledge concerning long-term risks of kidney living donation to help physicians for decision-making purposes and for providing information to the prospective live donors. Long-term risk of end-stage renal disease (ESRD) can be partially foreseen by trying to identify donors at risk of developing ‘de novo’ kidney diseases during life post-donation and by predicting lifetime ESRD risk. However, lifetime risk may be difficult to assess in young donors, especially in those having first-degree relatives with ESRD. The study from Norway also found an increased risk of death after living donor nephrectomy, which became visible only after >15 years of post-donation follow-up. However, these findings are likely to be largely the result of an overestimation due to the confounding effect related to a family history of renal disease. DESCARTES board members emphasize the importance of optimal risk–benefit assessment and proper information to the prospective donor, which should also include recommendations on health-promoting behaviour post-donation. © The Author 2017.

    Annual visits with a primary care provider (PCP) are recommended for living kidney donors to monitor long-term health postdonation, yet adherence to this recommendation is unknown. We surveyed 1170 living donors from our center from 1970 to 2012 to ascertain frequency of PCP visits pre- and postdonation. Interviews occurred median (IQR) 6.6 (3.8-11.0) years post-transplant. We used multivariate logistic regression to examine associations between donor characteristics and PCP visit frequency. Overall, only 18.6% had less-than-annual PCP follow-up postdonation. The strongest predictor of postdonation PCP visit frequency was predonation PCP visit frequency. Donors who had less-than-annual PCP visits before donation were substantially more likely to report less-than-annual PCP visits postdonation (OR= 9.8 14.4 21.0, P<.001). Men were more likely to report less-than-annual PCP visits postdonation (adjusted OR= 1.2 1.6 2.3, P<.01); this association was amplified in unmarried/noncohabiting men (aOR= 2.4 3.9 6.3, P<.001). Donors without college education were also more likely to report less-than-annual PCP visits postdonation (aOR= 1.3 1.8 2.5 , P=.001). The importance of annual PCP visits should be emphasized to all living donors, especially those with less education, men (particularly single men), and donors who did not see their PCP annually before donation. © 2017 John Wiley & Sons A/S.

    Lentine, Krista L; Schnitzler, Mark A; Xiao, Huiling; Davis, Connie L; Axelrod, David; Abbott, Kevin C; Salvalaggio, Paolo R; Burroughs, Thomas E; Saab, Georges; Brennan, Daniel C


    Little is known about associations of family health history with outcomes after kidney donation. Using a database wherein Organ Procurement and Transplantation Network identifiers for 4650 living kidney donors in 1987 to 2007 were linked to administrative data of a US private health insurer (2000-2007 claims), we examined associations of recipient illness history as a measure of family history with postdonation diagnoses and drug-treatment for hypertension and diabetes. Cox regression with left and right censoring was applied to estimate associations (adjusted hazards ratios, aHR) of recipient illness history with postnephrectomy donor diagnoses, stratified by donor-recipient relationship. Recipient end-stage renal disease from hypertension, as compared with other recipient end-stage renal disease causes, was associated with modest, significant increases in the age- and gender-adjusted relative risks of hypertension diagnosis (aHR, 1.37%; 95% confidence interval [CI], 1.08-1.74) after donor nephrectomy among related donors. After adjustment for age, gender, and race, recipient type 2 diabetes compared with non-diabetic recipient status was associated with twice the relative risk of postdonation diabetes (aHR, 2.14; 95% CI, 1.28-3.55; P=0.003) among related donors. These patterns were significant among white but not among non-white related donors. Recipient type 1 diabetes was associated with postdonation diabetes only in black related donors (aHR, 3.22; 95% CI, 1.04-9.98; P=0.04). Recipient illness did not correlate significantly with outcomes in unrelated donors. These data support a need for further study of family health history as a potential sociodemographic correlate of donor outcomes, including examination of potential mediating factors and variation in risk discrimination among donors of different racial groups.

  13. Deceased Donor Organs: What Can Be Done to Raise Donation Rates Using Evidence From Malaysia? (United States)

    Rasiah, R; Manikam, R; Chandrasekaran, S K; Naghavi, N; Mubarik, S; Mustafa, R; Pushparajan, S


    Organ donation rates have continued to fall seriously short of needs worldwide, with the lowest rates recorded among developing economies. This study seeks to analyze evidence from a developing economy to explore the usefulness of social psychological theory to solve the problem. The study deployed a large survey (n = 10 412) using a convenience sampling procedure targeted at increasing the number of Malaysians registered with the Ministry of Health, Malaysia who are willing to donate organs upon death. Structural equation modeling was deployed to estimate simultaneously the relative influence of cognitive and noncognitive variables on willingness to donate deceased organs. The cognitive factors of donation perception, socioeconomic status and financial incentives, and the noncognitive factors of demography and fear showed a high statistically significant (1%) relationship with willingness to donate organs after death. While financial incentives were significant, cash rewards showed the least impact. Donation perception showed the highest impact, which shows that the development of effective pedagogic programs with simultaneous improvements to the quality of services provided by medical personnel engaged in retrieving and transplanting deceased donor organs can help raise organ donation rates. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

  14. Living Kidney Donation Questionnaire (PCID-DVR-Ríos): Validation and Psychometric Characteristics in a Spanish-Speaking Population. (United States)

    Ríos, A; López-Navas, A I; De-Francisco, C; Sánchez, Á; Hernández, A M; Ramírez, P; Parrilla, P


    The attitude toward living kidney donation is important for certain promotion campaigns, however, there are few validated questionnaires in this regard. The aim of this work was to analyze the psychometric characteristics of the attitudes questionnaire about living renal donation, PCID-DVR-Ríos (Cuestionario del Proyecto Colaborativo Internacional Donante sobre Donación de Vivo Renal [Questionnaire of the International Collaborative Donor Project on Living Kidney Donation] developed by Dr Ríos) for the validation of the questionnaire in population of Spanish speakers. The sample studied represented the population >18 years of age, native and resident of Spain, stratified by age and sex. The measurement instrument was the PCID-DVR-Ríos questionnaire. Analysis of data was structured in several stages: an initial description of the data, exploratory factor analysis, item analysis, and internal consistency of the factors. The questionnaire consists of 11 items, distributed in 3 factors of 6, 3, and 2 items. This structure accounts for 63.995% of the total variance. By factors, the variance is distributed as follows: factor 1: 38.461%; factor 2: 14.228%; and factor 3: 11.306%. The analysis of items and internal consistency supported the trifactorial composition. Each factor is internally consistent (α1 = .80; α2 = .70; α3 = .55). The analyzed dimensions of the PCID-DVR Ríos questionnaire to analyze attitude toward living kidney donation showed a good fit in terms of factorial validity and internal consistency values.

    Full Text Available Whether vascular multiplicity should be considered as contraindication and therefore 'extended donor criterion' is still under debate.Data from all live kidney donors from 2006-2013 (n = 951 was retrospectively reviewed. Vascular anatomy as imaged by MRA, CTA or other modalities was compared with intraoperative findings. Furthermore, the influence of vascular multiplicity on outcome of donors and recipients was studied.In 237 out of 951 donors (25%, vascular multiplicity was present. CTA had the highest accuracy levels regarding vascular anatomy assessment. Regarding outcome of donors with vascular multiplicity, warm ischemia time (WIT and skin-to-skin time were significantly longer if arterial multiplicity (AM was present (5.1 vs. 4.0 mins and 202 vs. 178 mins. Skin-to-skin time was significantly longer, and complication rates were higher in donors with venous multiplicity (203 vs. 180 mins and 17.2% vs. 8.4%. Outcome of renal transplant recipients showed a significantly increased WIT (30 vs. 26.7 minutes, higher rate of DGF (13.9% vs. 6.9% and lower rate of BPAR (6.9% vs. 13.9% in patients receiving a kidney with AM compared to kidneys with singular anatomy.We conclude that vascular multiplicity should not be a contra-indication, since it has little impact on clinical outcome in the donor as well as in renal transplant recipients.

  18. Organ donation in Switzerland--an analysis of factors associated with consent rate.

    Directory of Open Access Journals (Sweden)

    Julius Weiss

    Full Text Available BACKGROUND AND AIM: Switzerland has a low post mortem organ donation rate. Here we examine variables that are associated with the consent of the deceased's next of kin (NOK for organ donation, which is a prerequisite for donation in Switzerland. METHODS AND ANALYSIS: During one year, we registered information from NOK of all deceased patients in Swiss intensive care units, who were approached for consent to organ donation. We collected data on patient demographics, characteristics of NOK, factors related to the request process and to the clinical setting. We analyzed the association of collected predictors with consent rate using univariable logistic regression models; predictors with p-values <0.2 were selected for a multivariable logistic regression. RESULTS: Of 266 NOK approached for consent, consent was given in 137 (51.5% cases. In multivariable analysis, we found associations of consent rates with Swiss nationality (OR 3.09, 95% CI: 1.46-6.54 and German language area (OR 0.31, 95% CI: 0.14-0.73. Consent rates tended to be higher if a parent was present during the request (OR 1.76, 95% CI: 0.93-3.33 and if the request was done before brain death was formally declared (OR 1.87, 95% CI: 0.90-3.87. CONCLUSION: Establishing an atmosphere of trust between the medical staff putting forward a request and the NOK, allowing sufficient time for the NOK to consider donation, and respecting personal values and cultural differences, could be of importance for increasing donation rates. Additional measures are needed to address the pronounced differences in consent rates between language regions.

  19. Predonation Direct and Indirect Costs Incurred by Adults Who Donated a Kidney: Findings From the KDOC Study. (United States)

    Rodrigue, J R; Schold, J D; Morrissey, P; Whiting, J; Vella, J; Kayler, L K; Katz, D; Jones, J; Kaplan, B; Fleishman, A; Pavlakis, M; Mandelbrot, D A


    Limited information exists on the predonation costs incurred by eventual living kidney donors (LKDs). Expenses related to completion of the donation evaluation were collected from 194 LKDs participating in the multi-center, prospective Kidney Donor Outcomes Cohort (KDOC) Study. Most LKDs (n = 187, 96%) reported one or more direct costs, including ground transportation (80%), healthcare (24%), lodging (17%) and air transportation (14%), totaling $101 484 (USD; mean = $523 ± 942). Excluding paid vacation or sick leave, donor and companion lost wages totaled $35 918 (mean = $187 ± 556) and $14 378 (mean = $76 ± 311), respectively. One-third of LKDs used paid vacation or sick leave to avoid incurring lost wages. Few LKDs reported receiving financial support from the transplant candidate (6%), transplant candidate's family (3%), a nonprofit organization (3%), the National Living Donor Assistance Center (7%), or transplant center (3%). Higher total costs were significantly associated with longer distance traveled to the transplant center (p costs were not associated with age, sex, race/ethnicity, household income, marital status, insurance status, or transplant center. Moderate predonation direct and indirect costs are common for adults who complete the donation evaluation. Potential LKDs should be advised of these possible costs, and the transplant community should examine additional strategies to reimburse donors for them. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

  20. Eye Donation Awareness and Conversion Rate in Hospital Cornea Retrieval Programme in a Tertiary Hospital of Central India. (United States)

    Sharma, Bhavana; Shrivastava, Ulka; Kumar, Kavita; Baghel, Rajendra; Khan, Farhana; Kulkarni, Shridhar


    Corneal blindness accounts for 6-8 million blinds in the world. In India, it is estimated that there are approximately 6.8 million people who have vision less than 6/60 in at least one eye due to corneal diseases. This study was done to assess the awareness about eye donation amongst attendants of critically ill and deceased patients, their willingness to donate eyes, the efficacy of grief counselling by Eye Donation Counsellors (EDC), its impact on the conversion rate and the reasons for poor donation rate. This prospective hospital based study was done in 554 participants (guardians of critically ill and deceased subjects) to understand the awareness of eye donation. Factors related to willingness for eye donation that influenced conversion to actual donation were evaluated. Data was analysed with tests for statistical significance: Chi square test; pdonation, time taken for motivation remained less than 12 hours, which was statistically significant (Chi square=106. pdonation in comparison to those who were unaware in a ratio of 2:1. Grief counsellors (57.5%) had the most influence among the causes that were facilitators of donation. Utilizing the services of eye donation counsellors is a promising way to motivate the guardians of deceased. Increasing the awareness in society, rendering simple assistances to next of kin and speeding the medico legal formalities can go a long way in increasing the conversion rate and hence actual donation.

  1. Confirmed Transmission of Bacterial or Fungal Infection to Kidney Transplant Recipients from Donated After Cardiac Death (DCD) Donors in China: A Single-Center Analysis. (United States)

    Wan, Qiquan; Liu, Huanmiao; Ye, Shaojun; Ye, Qifa


    BACKGROUND We aimed to investigate blood and urine cultures of donated after cardiac death (DCD) donors and report the cases of confirmed (proven/probable) transmission of bacterial or fungal infection from donors to kidney recipients. MATERIAL AND METHODS Seventy-eight DCD donors between 2010 and 2016 were included. Sixty-one DCD donors underwent blood cultures and 22 episodes of bacteremias developed in 18 donors. Forty-three donors underwent urine cultures and 14 donors experienced 17 episodes of urinary infections. RESULTS Seven of 154 (4.5%) kidney recipients developed confirmed donor-derived bacterial or fungal infections. Inappropriate use of antibiotics in donor was a risk factor for donor-derived infection (p=0.048). The use of FK506 was more frequent in recipients without donor-derived infection than those with donor-derived infection (p=0.033). Recipients with donor-derived infection were associated with higher mortality and graft loss (42.9% and 28.6%, respectively), when compared with those without donor-derived infection (4.8% each). Three kidney recipients with donor-derived infection died; one death was due to multi-organ failure caused by Candida albicans, and two were related to rupture of the renal artery; two of them did not receive appropriate antimicrobial therapy after infection. CONCLUSIONS Our kidney recipients showed high occurrence rates of donor-derived infection. Recipients with donor-derived infection were associated with higher mortality and graft loss than those without donor-derived infection. The majority of recipients with donor-derived infection who died did not receive appropriate antimicrobial therapy after infection.

  2. Decadal analysis of deceased organ donation in Spain and the United States linking an increased donation rate and the utilization of older donors. (United States)

    Halldorson, Jeff; Roberts, John Paul


    After the foundation of the National Transplant Organization, Spanish rates of deceased donor donation rapidly outpaced US growth over the decade from 1989 to 1999. An analysis of the following decade, 1999-2009, demonstrated a markedly flattened growth curve for Spanish deceased donor organ procurement, which increased only 2.4% from 33.6 to 34.4 donors per million population (pmp). In comparison, over the same decade in the United States, the rate of deceased donation increased from 20.9 to 26.3 donors pmp (25.8%). An age group comparison demonstrated a much higher donation rate among older donors in Spain. For example, the number of donors older than 70 years increased from 3.8 to 8.8 pmp (a 132% increase), and they now constitute 25.4% of all Spanish organ donors. In contrast, the number of US donors older than 70 years increased from 1.0 to 1.3 pmp, and they constitute only 4.4% of total deceased donors. Over the same decade, the number of younger donors (15-30 years old) decreased from 6.6 to 2.5 pmp (a 62% decrease) in Spain, and this contrasted with a slightly increased US donation rate for the same age subgroup (a 15.5% increase from 5.8 to 6.7 pmp). Although older donors were more rarely used in the United States, growth in donation over the 2 decades (1989-2009) was strongly associated with the utilization of donors aged 65 or older (P < 0.01). United Network for Organ Sharing regions demonstrated significant differences in utilization rates for older donors. In conclusion, strategies aimed toward achieving US donation rates equivalent to the Spanish benchmark should target improved utilization rates for older donors in the United States instead of emulating elements of the Spanish organ procurement system. © 2013 American Association for the Study of Liver Diseases.

  3. From blood donation to kidney sales: the gift relationship and transplant commercialism. (United States)

    Koplin, Julian J


    In The Gift Relationship, Richard Titmuss argued that the practice of altruistic blood donation fosters social solidarity while markets in blood erode it. This paper considers the implications of this line of argument for the organ market debate. I defend Titmuss' arguments against a number of criticisms and respond to claims that Titmuss' work is not relevant to the context of live donor organ transplantation. I conclude that Titmuss' arguments are more resilient than many advocates of organ markets suggest, and more relevant to the debate than is commonly appreciated.

  5. Protocol of a randomized controlled trial of culturally sensitive interventions to improve African Americans' and non-African Americans' early, shared, and informed consideration of live kidney transplantation: the Talking About Live Kidney Donation (TALK) Study. (United States)

    Live kidney transplantation (LKT) is underutilized, particularly among ethnic/racial minorities. The effectiveness of culturally sensitive educational and behavioral interventions to encourage patients' early, shared (with family and health care providers) and informed consideration of LKT and ameliorate disparities in consideration of LKT is unknown. We report the protocol of the Talking About Live Kidney Donation (TALK) Study, a two-phase study utilizing qualitative and quantitative research methods to design and test culturally sensitive interventions to improve patients' shared and informed consideration of LKT. Study Phase 1 involved the evidence-based development of culturally sensitive written and audiovisual educational materials as well as a social worker intervention to encourage patients' engagement in shared and informed consideration of LKT. In Study Phase 2, we are currently conducting a randomized controlled trial in which participants with progressing chronic kidney disease receive: 1) usual care by their nephrologists, 2) usual care plus the educational materials, or 3) usual care plus the educational materials and the social worker intervention. The primary outcome of the randomized controlled trial will include patients' self-reported rates of consideration of LKT (including family discussions of LKT, patient-physician discussions of LKT, and identification of an LKT donor). We will also assess differences in rates of consideration of LKT among African Americans and non-African Americans. The TALK Study rigorously developed and is currently testing the effectiveness of culturally sensitive interventions to improve patients' and families' consideration of LKT. Results from TALK will provide needed evidence on ways to enhance consideration of this optimal treatment for patients with end stage renal disease. number, NCT00932334.

  6. Increasing organ donation rates by revealing recipient details to families of potential donors. (United States)

    Shaw, David; Gardiner, Dale


    Many families refuse to consent to donation from their deceased relatives or over-rule the consent given before death by the patient, but giving families more information about the potential recipients of organs could reduce refusal rates. In this paper, we analyse arguments for and against doing so, and conclude that this strategy should be attempted. While it would be impractical and possibly unethical to give details of actual potential recipients, generic, realistic information about the people who could benefit from organs should be provided to families before they make a decision about donation or attempt to over-rule it. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    As the need for the organ donation increases, strategies to increase kidney transplantation (KT) through expanded living donation have become essential. These include kidney paired donation (KPD) programs and desensitization in incompatible transplantations. KPD enables kidney transplant candidates with incompatible living donors to join a registry with other incompatible pairs in order to find potentially compatible living donor. Positive cross match and ABO incompatible transplantation has been successfully accomplished in selective cases with several pre-conditionings. Patients who are both difficult-to-match due to broad sensitization and hard-to-desensitize because of donor conditions can often be successfully transplanted through a combination of KPD and desensitization. According to the existing data, KPD can increase the number of KTs from living donors with excellent clinical results. This is also a cost-effective treatment as compared with dialysis and desensitization protocols. We carried out 3-way KPD transplantation with one highly sensitized, positive cross match pair and with two ABO incompatible pairs. Herein we report our first successful 3-way KPD transplantation in a single center. To maximize donor-recipient matching and minimize immunologic risk, KPD programs should use proper algorithms with desensitization to identify optimal donor with simultaneous two-, three- or more complex multi-way exchanges. © 2018 The Korean Academy of Medical Sciences.

  8. Understanding barriers and outcomes of unspecified (non-directed altruistic) kidney donation from both professional's and patient's perspectives: research protocol for a national multicentre mixed-methods prospective cohort study. (United States)

    Living donation accounts for over one-third of all kidney transplants taking place in the UK. 1 The concept of anonymously donating a kidney to a stranger (non-directed altruistic or unspecified kidney donation (UKD)) remains uncomfortable for some clinicians, principally due to concerns about the motivations and long-term physical and psychological outcomes in this donor group. The research programme aims to provide a comprehensive assessment of the unspecified donor programme in the UK. It aims to identify reasons for variations in practice across centres, explore outcomes for donors and ascertain barriers and facilitators to UKD, as well as assess the economic implications of unspecified donation. The research programme will adopt a mixed-methods approach to assessing UKD nationally using focus groups, interviews and questionnaires. Two study populations will be investigated. The first will include transplant professionals involved in unspecified kidney donation. The second will include a 5-year prospective cohort of individuals who present to any of the 23 UK transplant centres as a potential unspecified living kidney donor. Physical and psychological outcomes will be followed up to 1 year following donation or withdrawal from the donation process. A matched sample of specified donors (those donating to someone they know) will be recruited as a control group. Further qualitative work consisting of interviews will be performed on a purposive sample of unspecified donors from both groups (those who do and do not donate). The findings will be reported to NHS Blood and Transplant and the British Transplant Society with a view to developing national guidelines and a protocol for the management of those presenting for unspecified donation.

  9. Changing Metrics of Organ Procurement Organization Performance in Order to Increase Organ Donation Rates in the United States. (United States)

    Goldberg, D; Kallan, M J; Fu, L; Ciccarone, M; Ramirez, J; Rosenberg, P; Arnold, J; Segal, G; Moritsugu, K P; Nathan, H; Hasz, R; Abt, P L


    The shortage of deceased-donor organs is compounded by donation metrics that fail to account for the total pool of possible donors, leading to ambiguous donor statistics. We sought to assess potential metrics of organ procurement organizations (OPOs) utilizing data from the Nationwide Inpatient Sample (NIS) from 2009-2012 and State Inpatient Databases (SIDs) from 2008-2014. A possible donor was defined as a ventilated inpatient death ≤75 years of age, without multi-organ system failure, sepsis, or cancer, whose cause of death was consistent with organ donation. These estimates were compared to patient-level data from chart review from two large OPOs. Among 2,907,658 inpatient deaths from 2009-2012, 96,028 (3.3%) were a "possible deceased-organ donor." The two proposed metrics of OPO performance were: (1) donation percentage (percentage of possible deceased-donors who become actual donors; range: 20.0-57.0%); and (2) organs transplanted per possible donor (range: 0.52-1.74). These metrics allow for comparisons of OPO performance and geographic-level donation rates, and identify areas in greatest need of interventions to improve donation rates. We demonstrate that administrative data can be used to identify possible deceased donors in the US and could be a data source for CMS to implement new OPO performance metrics in a standardized fashion. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

  10. Development of a liquid chromatography tandem mass spectrometry method for iothalamate measurement to assess renal function for potential kidney donation. (United States)

    Rhea, Jeanne M; Ritchie, James C; Molinaro, Ross J


    Chronic kidney disease often goes undetected due to the insensitivity of current methods to accurately assess glomerular filtration rate (GFR) in early stages of renal dysfunction. The clearance of exogenously introduced iothalamate, a commonly used radiopaque agent, is an alternative to inulin clearance for the assessment of renal function and its use in calculating GFR can serve as a screening tool for kidney transplant donors. A method was developed to measure iothalamate in plasma and urine samples by HPLC combined with electrospray positive ionization tandem mass spectrometry (MS/MS). Iothalamate is isolated from plasma by methanol extraction and urine using a quick-spin filtration approach, then monitored by multiple reaction monitoring using the hydrogen adduct mass transitions. Iohexol was used as an internal standard. Iothalamate was measured within an analytical run time of 5 min, with a lower limit of quantification of 18.75 ng/ml. The intraassay and interassay variations of the plasma and urine iothalamate assays were both calculated using the patient's urine flow rate and plasma and urine iothalamate values. Linear correlations tested by LC-MS/MS and an accepted capillary electrophoresis (CE) assay showed similar results (GFR, r=0.92, Sy/x=10.3). We developed and validated an LC-MS/MS method for quantitating iothalamate in plasma and urine to calculate GFR used for screening potential kidney donors in our hospital system. A less sensitive mass spectrometry system does not sacrifice analytical or clinical sensitivity for measuring GFR. Copyright © 2012 Elsevier B.V. All rights reserved.

  11. Attitudes toward strategies to increase organ donation: views of the general public and health professionals. (United States)

    Barnieh, Lianne; Klarenbach, Scott; Gill, John S; Caulfield, Tim; Manns, Braden


    The acceptability of financial incentives for organ donation is contentious. This study sought to determine (1) the acceptability of expense reimbursement or financial incentives by the general public, health professionals involved with organ donation and transplantation, and those with or affected by kidney disease and (2) for the public, whether financial incentives would alter their willingness to consider donation. Web-based survey administered to members of the Canadian public, health professionals, and people with or affected by kidney disease asking questions regarding acceptability of strategies to increase living and deceased kidney donation and willingness to donate a kidney under various financial incentives. Responses were collected from 2004 members of the Canadian public October 11-18, 2011; responses from health professionals (n=339) and people with or affected by kidney disease (n=268) were collected during a 4-week period commencing October 11, 2011. Acceptability of one or more financial incentives to increase deceased and living donation was noted in >70% and 40% of all groups, respectively. Support for monetary payment for living donors was 45%, 14%, and 27% for the public, health professionals, and people with or affected by kidney disease, respectively. Overall, reimbursement of funeral expenses for deceased donors and a tax break for living donors were the most acceptable. The general public views regulated financial incentives for living and deceased donation to be acceptable. Future research needs to examine the impact of financial incentives on rates of deceased and living donors.

    Dos Santos, M J; Leal de Moraes, E; Santini Martins, M; Carlos de Almeida, E; Borges de Barros E Silva, L; Urias, V; Silvano Corrêa Pacheco Furtado, M C; Brito Nunes, Á; El Hage, S


    The goal of this study was to identify the tendency toward donations of tissue and organs from donors with brain death between 2001 and 2016 as registered by an organ procurement organization in São Paulo City. This quantitative, retrospective, exploratory study encompassed all Tissue and Organ Donation Terms signed between 2001 and 2016. A logistic regression model was applied to verify whether there was an upward or downward trend in donation. After statistical analysis, a significant change trend was identified in skin, bones, valve, vessel, heart, lung, and pancreas donations, indicating an increase in the donation rate through the years. The donation rate did not show changes over the years for donations of liver, kidneys, and corneas. The decision-making process regarding organ and tissue donation is restricted not only to the dilemma of whether to donate but another question then arises as well: which organs and tissues are to be donated? The discrepancy between the authorization for organ donation and the authorization for tissue donation, as well as the option for one or another organ and/or tissue, must be thoroughly examined because these factors directly affect the number of transplants and acquirements effectively accomplished. These factors may be related to explaining to one's relatives aspects of the surgery, body reassembling, and usage of such organs and/or tissues. They may also be related to the lack of knowledge concerning organ donation and the symbolism represented by the organ and/or tissue, among other factors. Copyright © 2018 Elsevier Inc.

    To describe the rationale, methodology, design, and interventional approach of a mobile health education program designed for African Americans with end stage renal disease (ESRD) to increase knowledge and self-efficacy to approach others about their need for a living donor kidney transplant (LDKT). The Living Organ Video Educated Donors (LOVED) program is a theory-guided iterative designed, mixed methods study incorporating three phases: 1) a formative evaluation using focus groups to develop program content and approach; 2) a 2-month proof of concept trial (n=27) to primarily investigate acceptability, tolerability and investigate increases of LDKT knowledge and self-efficacy; and 3) a 6-month, 2-arm, 60-person feasibility randomized control trial (RCT) to primarily investigate increases in LDKT knowledge and self-efficacy, and secondarily, to increase the number of living donor inquiries, medical evaluations, and LDKTs. The 8-week LOVED program includes an interactive web-based app delivered on 10″ tablet computer incorporating weekly interactive video education modules, weekly group video chat sessions with an African American navigator who has had LDKT and other group interactions for support and improve strategies to promote their need for a kidney. Phase 1 and 2 have been completed and the program is currently enrolling for the feasibility RCT. Phase 2 experienced 100% retention rates with 91% adherence completing the video modules and 88% minimum adherence to the video chat sessions. We are in the early stages of an RCT to evaluate the LOVED program; to date, we have found high tolerability reported from Phase 2. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Factors influencing the reimbursement rate of egg donation within a competitive free-market system. (United States)

    Heng, Boon Chin


    The current situation of oocyte donation in the USA serves as a useful paradigm for a laissez-faire free-market model of egg donor reimbursement, based on supply and demand. There is a rapidly emerging consensus of what would be considered desirable attributes in an egg donor, which would in turn determine her market value in financial reimbursement. First and foremost is the race and ethnicity of the donor. As expected, the shortage of egg donors from some ethnic groups such as East Asians and Jews has resulted in higher reimbursement rates for donors of such ethnicity. Second is the educational attainment of the donor, in particular high scholastic aptitude test scores and degrees from prestigious universities. Third is the employment status and career of the prospective donor. Last, but not least, are the personal esthetics of the egg donor, her physical appearance, from complexion to stature. These can be summarized as the Four Es: ethnicity, education, employment and esthetics, which are somewhat analogous to the Four Cs of diamond price valuation (colour, clarity, carat and cut). Although such an analogy may appear rather superficial, the free-market systems that have evolved in response to a growing demand for these two completely unrelated items are uncannily similar.

  15. Current Challenges of Organ Donation Programs in Syria (United States)

    Saeed, B.


    Background: Renal transplantation is the optimal treatment for the majority of patients with end-stage renal disease. Objective: To examine the donor characteristics of kidney transplants in Syria and the impact of national Syrian legislation on the evolution of kidney transplantation activities in the private and public sectors. Methods: Available data on all kidney transplants performed in Syria over the last 2 decades was retrospectively analyzed to assess the characteristics of kidney donors and recipients with a focus upon transplants since 2003. Results: The kidney transplant rate has increased from 7 kidney transplants per million populations in 2002 to more than 17 in 2007. In the meantime, a substantial decline in the rate of kidney transplantation performed on Syrian nationals abroad was observed from 65% of all kidney transplantations in 1998 to less than 2% in 2007. Despite the prohibition to buy a kidney in Syria, vendors had found ways to sell their kidneys through disreputable brokers. Potential related donors were not inclined to donate kidneys to their relatives as long as kidneys could be bought from a non-related donor. By 2008, the percent of related donors in private sector represented only 8% of all donors, as compared to 50% in public hospitals. Consequently, in January 2008, the government of Syria issued a pronouncement restricting kidney transplantation to the public sector with a new national regulatory oversight of transplantation practices. Since this 2008 Administrative Order was promulgated, the kidney transplant rate in public hospitals has substantially increased by 55% with the establishment of new public transplant centers in the 3 largest cities in Syria. Conclusion: The recommendations of the Istanbul Declaration and the Revised Guiding Principles of the World Health Organization have yet to be implemented in Syria but the expansion of kidney transplants in the public sector is an important initial step for initiating a deceased

    Cristina Candido

    Full Text Available Abstract Introduction: Women regain fertility a few time after renal transplantation. However, viability of pregnancy and maternal complications are still unclear. Objective: To describe the outcomes of pregnancies in kidney transplanted patients, focusing on maternal complications. Methods: Retrospective study of pregnancies in kidney transplanted patients between 2004 and 2014, followed up 12 months after delivery. Each pregnancy was considered an event. Results: There were 53 pregnancies in 36 patients. Mean age was 28 ± 5years. Pregnancy occurred 4.4 ± 3.0 years post-transplant. Immunosuppression before conception was tacrolimus, azathioprine, and prednisone in 74% of the cases. There were 15% miscarriages in the 1st trimester and 8% in 2nd trimester. In 41% of the cases, it was necessary to induce labor. From all births, 22% were premature and 17% very premature. There were 5% stillbirths and 5% of neonatal deaths. De novo proteinuria occurred in 60%, urinary tract infection in 23%, preeclampsia in 11%, acute rejection in 6%, and graft loss in 2% of the cases. It was observed a significant increase in creatinine at preconception comparing to 3rd trimester and follow-up (1.17 vs. 1.46 vs. 1.59 mg/dL, p < 0.001. Conclusion: Although the sample is limited, the number of miscarriages was higher than in the general population, with high rates of maternal complications. Sustained increase of creatinine suggests increased risk of graft loss in long-term.

    Conclusion: This study shows that the relationship of the donor to their recipient resulted in significant differences in the postoperative GFR and graft loss of the recipients. Recipients' kidneys donated from the spouse had the worst GFR compared to other groups.

  18. Functional principal component analysis of glomerular filtration rate curves after kidney transplant. (United States)

    Dong, Jianghu J; Wang, Liangliang; Gill, Jagbir; Cao, Jiguo


    This article is motivated by some longitudinal clinical data of kidney transplant recipients, where kidney function progression is recorded as the estimated glomerular filtration rates at multiple time points post kidney transplantation. We propose to use the functional principal component analysis method to explore the major source of variations of glomerular filtration rate curves. We find that the estimated functional principal component scores can be used to cluster glomerular filtration rate curves. Ordering functional principal component scores can detect abnormal glomerular filtration rate curves. Finally, functional principal component analysis can effectively estimate missing glomerular filtration rate values and predict future glomerular filtration rate values.

    Carla Burballa


    Full Text Available Introduction: The evaluation of the measured Glomerular Filtration Rate (mGFR or estimated Glomerular Filtration Rate (eGFR is key in the proper assessment of the renal function of potential kidney donors. We aim to study the correlation between glomerular filtration rate estimation equations and the measured methods for determining renal function. Material and methods: We analyzed the relationship between baseline GFR values measured by Tc-99m-DTPA (diethylene-triamine-pentaacetate and those estimated by the four-variable Modification of Diet in Renal Disease (MDRD4 and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI equations in a series of living donors at our institution. Results: We included 64 donors (70.6% females; mean age 48.3 ± 11 years. Baseline creatinine was 0.8 ± 0.1 mg/dl and it was 1.1 ± 0.2 mg/dl one year after donation. The equations underestimated GFR when measured by Tc99m-DTPA (MDRD4 – 9.4 ± 25 ml/min, P < .05, and CKD-EPI – 4.4 ± 21 ml/min. The correlation between estimation equations and the measured method was superior for CKD-EPI (r = .41; P < .004 than for MDRD4 (r = .27; P < .05. eGFR decreased to 59.6 ± 11 (MDRD4 and 66.2 ± 14 ml/min (CKD-EPI one year after donation. This means a mean eGFR reduction of 28.2 ± 16.7 ml/min (MDRD4 and 27.31 ± 14.4 ml/min (CKD-EPI at one year. Conclusions: In our experience, CKD-EPI is the equation that better correlates with mGFR-Tc99m-DTPA when assessing renal function for donor screening purposes.

    This study's purpose was to investigate the attitudes toward organ donation among renal transplantation patients and their caregivers. In addition, we sought to explore the impact factors that affect their attitudes toward deceased organ donation. A self-administrated questionnaire was used, which consisted of two parts: 1) demographic data, and 2) transplantation and donation-related data. This study was conducted in three transplantation follow-up centers in three hospitals using a cross-sectional approach. SPSS 17.0 software was used to analysis descriptive and inferential statistics for data. The responses were analyzed using descriptive statistics and logistic regression analysis. We received 426 effective questionnaires. The renal transplantation patients' mean age was 40.84 years. Among these patients, 67.8% were willing to accept the organ transplantation surgery for their relatives, 67.4% were willing to donate a living kidney to a close relative, 62.7% were willing to donate organs after death, 53.5% were willing to register in the national organ donation system, and 51.4% were willing to sign the organ donation consent when facing their relatives becoming a potential organ donor. Age, marriage status, education level, understanding of transplantation procedures and understanding of donation procedures had statistical significance in the difference of the attitudes toward donate their organs after death (P donate organs after death than their caregivers, but both their attitudes toward deceased donation were not very optimistic. There is a significant relationship between participants' willingness and knowledge of organ donation; patients with more understanding of the transplantation and donation procedure were more willing to donate organs after death. Affected by traditional values such as Confucianism, many people still cannot accept registering in the national organ donation system or sign the organ donation consent when facing their relatives

  7. A comparison of human immunodeficiency virus, hepatitis C virus, hepatitis B virus, and human T-lymphotropic virus marker rates for directed versus volunteer blood donations to the American Red Cross during 2005 to 2010. (United States)

    Dorsey, Kerri A; Moritz, Erin D; Steele, Whitney R; Eder, Anne F; Stramer, Susan L


    At most US blood centers, patients may still opt to choose specific donors to give blood for their anticipated transfusion needs. However, there is little evidence of improved safety with directed donation when compared to volunteer donation. The percentage of directed donations made to the American Red Cross (ARC) from 1995 to 2010 was determined. Infectious disease marker rates for human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), and human T-lymphotropic virus (HTLV) were calculated for volunteer and directed donations made from 2005 to 2010. Odds ratios (ORs) were calculated to compare marker-positive rates of directed donations to volunteer donations. The percentage of donations from directed donors declined from 1.6% in 1995 to 0.12% in 2010. From 2005 to 2010, the ARC collected 38,894,782 volunteer and 69,869 directed donations. Rates of HIV, HCV, HBV, and HTLV for volunteer donations were 2.9, 32.2, 12.4, and 2.5 per 100,000 donations, respectively; for directed, the rates were 7.2, 93.0, 40.1, and 18.6 per 100,000. After demographics and first-time or repeat status were adjusted for, corresponding ORs of viral marker positivity in directed versus volunteer donations were not significant for HIV, HBV, or HTLV and significant for HCV (OR, 0.7; 95% confidence interval, 0.50-0.90). Directed donations have declined by 92% at the ARC since 1995, but have higher viral marker rates than volunteer donations. The difference can be explained in part by the effects of first-time or repeat status of the donors. Patients considering directed donation should be appropriately counseled about the potential risks. © 2012 American Association of Blood Banks.

  8. OPTN/SRTR 2013 Annual Data Report: deceased organ donation. (United States)

    Israni, A K; Zaun, D A; Rosendale, J D; Snyder, J J; Kasiske, B L


    The status of deceased organ donation is assessed using metrics such as donation/conversation rate, organ yield, and rate of organs recovered for transplant and not transplanted. These metrics are based on eligible deaths (brain death of a person aged 70 years or younger) as well as on actual donors. The 9132 eligible deaths reported in 2013 represented a slight increase over 2012. The donation/conversion rate was 71.3 eligible donors per 100 eligible deaths, a slight decline from 2012, and varied by donation service area from 50.0 to 87.0. The number of organs recovered per donor, 3.55, also varied by donation service area, from 2.79 to 4.10. The mean number of organs transplanted per donor was 3.08 in 2013, slightly higher than 3.02 in 2012. The mean observed/expected organ yield ratio for kidneys varied from 0.86 to 1.18; for pancreata, from 0.29 to 2.59; for livers, from 0.69 to 1.17; for hearts, from 0.68 to 1.41; and for lungs, from 0.33 to 1.41. The rate of organs recovered for transplant and not transplanted in 2013 for all organs combined was 0.13 per recovered organ, slightly lower than the rate of 0.14 in 2012. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Our aim was to develop and test an educational program to support well-informed decision making among patients and their social network regarding living donor kidney transplantation (LDKT). One hundred sixty-three patients who were unable to find a living donor were randomized to standard care or standard care plus home-based education. In the education condition, patients and members of their social network participated in home-based educational meetings and discussed renal replacement therapy options. Patients and invitees completed pre-post self-report questionnaires measuring knowledge, risk perception, communication, self-efficacy and subjective norm. LDKT activities were observed for 6 months postintervention. Patients in the experimental group showed significantly more improvements in knowledge (p communication (p = 0.012) compared with the control group.

  10. Attempt to define a repair threshold (or the prospects for kidneys of reduced uptake rate)

    International Nuclear Information System (INIS)

    Le Duc, A.; Camey, M.; Bourguignon, M.; CEA, 91 - Orsay


    The definition of a repair threshold hardly seems realistic whatever the etiology considered. It is impossible to set a lower uptake limit below which a kidney does not recover, nor an upper limit above which recuperation is inevitable. To be able to use an uptake rate result with discernment it is useful to know two facts: '0 degradation' prospects exist for very diseased kidneys; the prospects of recovery are very appreciable for kidneys subjected to an infected stasis, amply justifying conservation in uptake regions around 20%. All this obviously needs confirmation which can only be obtained by adding a functional study to certain files which already date back significantly [fr

    Full Text Available Objective: It was aimed to present the acceptance rate of organ donation of cases that were diagnosed with brain death and evaluated in terms of their demographic and clinical properties retrospectively in Adıyaman University Training and Research Hospital. Material and Method: In the intensive care unit of our hospital, cases that were diagnosed with brain death between the dates of January 2008 and December 2014 were retrospectively analyzed. Cases were evaluated in terms of age, sex, cause of brain death, blood groups, donation status, reasons for acceptance or rejection of donation, cardiac arrest, vasopressin treatment, laboratory test results, arterial blood gas values before and after the apnea test, intensive care unit follow-up durations, apnea test, seasonal and annual distribution. Also, potential donors and recipients were analyzed in accordance with their demographic characteristics. Results: The diagnosis of brain death was made in totally 57 cases; of those, 34 (59.6% were men and 23 (40.4% were women. The most common causes for brain death were traumatic subarachnoid hemorrhage (SAH and intracerebral hematoma. Most of the cases had A Rh+ blood type (n=18, 31.5% and the rate of brain death was 4.7 times higher in Rh (+ patients in comparison to Rh (- patients. The rate of incidence of cardiac arrest was 12.3% (n=7, and it was more common in traumatic SAH patients. The rate of receiving vasopressor therapy was 21.1% (n=12, and the mean duration of therapy was 1.3±0.8 days. It was more commonly used in traumatic SAH patients (n=10. The follow-up period was 2.7±3.2 (minimum: 1, maximum: 17 days. Five patients were considered to be organ donors. The most common reason for acceptance of donation was the effect of organ transplantation coordinator during family interviews (n=3, 60%. In total, 4 livers, 5 kidneys and 1 heart transplantation operations were performed to 10 patients. Conclusion: Due to problems in organ donation

  14. Knowledge and Attitude Regarding Organ Donation among Medical Students

    Directory of Open Access Journals (Sweden)

    Bharambe Vaishaly K.


    Full Text Available Introduction. All over the world people on organ transplant waiting lists die due to shortage of donor organs. The success of organ donation program needs education of the population regarding organ donation for which healthcare professionals are most suitable. The present study was taken up to assess the knowledge and attitude of 1st, 2nd and 3rd year medical students about organ donation. Methods. A specially designed self-administered questionnaire was distributed amongst all willing 1st, 2nd and 3rd year medical students at our Medical College and later analyzed statistically. Results. A total of 157, 145 and 92 students from each year of medical education respectively gave their consent for participation in the study. Awareness regarding organ donation was found to be 98.7-100%, 69.4% claimed television as their source of information regarding organ donation and 46.7% stated that it is possible for patient to recover from brain death. The awareness regarding eye, liver, heart and kidney donations was found to be 92.4%, 87%, 87% and 97.8%, respectively. 87% of medical students were aware of need for legal supervision, and awareness regarding the existing laws was found to be 57.6%. Conclusion. Medical students had a high level of awareness and a positive attitude towards organ donation. However, knowledge regarding “brain-death”, organs and tissues donated, legislation and ethical issues was poor. A teaching intervention designed to specifically address these issues could help increase the confidence of the health-care professionals and may result finally in increased organ procurement rates.

  15. Aging and physiological changes of the kidneys including changes in glomerular filtration rate. (United States)

    Musso, Carlos G; Oreopoulos, Dimitrios G


    In addition to the structural changes in the kidney associated with aging, physiological changes in renal function are also found in older adults, such as decreased glomerular filtration rate, vascular dysautonomia, altered tubular handling of creatinine, reduction in sodium reabsorption and potassium secretion, and diminished renal reserve. These alterations make aged individuals susceptible to the development of clinical conditions in response to usual stimuli that would otherwise be compensated for in younger individuals, including acute kidney injury, volume depletion and overload, disorders of serum sodium and potassium concentration, and toxic reactions to water-soluble drugs excreted by the kidneys. Additionally, the preservation with aging of a normal urinalysis, normal serum urea and creatinine values, erythropoietin synthesis, and normal phosphorus, calcium and magnesium tubular handling distinguishes decreased GFR due to normal aging from that due to chronic kidney disease.

  16. Beneficial Effect of Conversion to Belatacept in Kidney-Transplant Patients with a Low Glomerular-Filtration Rate

    Directory of Open Access Journals (Sweden)

    Julie Belliere


    Full Text Available Belatacept has been found to be efficient at preserving good kidney function in maintenance kidney-transplant patients. Herein, we report on the use of belatacept as a rescue therapy for two kidney-transplant patients presenting with severe adverse events after treatment with calcineurin inhibitors (CNIs and mammalian target-of-rapamycin (mTOR inhibitors. Two kidney-transplant patients developed severely impaired kidney function after receiving CNIs. The use of everolimus was associated with severe angioedema. Belatacept was then successfully used to improve kidney function in both cases, even though estimated glomerular-filtration rate before conversion was <20 mL/min. These case reports show that belatacept can be used as a rescue therapy, even if kidney function is very low in kidney-transplant patients who cannot tolerate CNIs and/or mTOR inhibitors.

  20. Fostering repeat donations in Ghana. (United States)

    Owusu-Ofori, S; Asenso-Mensah, K; Boateng, P; Sarkodie, F; Allain, J-P


    Most African countries are challenged in recruiting and retaining voluntary blood donors by cost and other complexities and in establishing and implementing national blood policies. The availability of replacement donors who are a cheaper source of blood has not enhanced repeat voluntary donor initiatives. An overview of activities for recruiting and retaining voluntary blood donors was carried out. Donor records from mobile sessions were reviewed from 2002 to 2008. A total of 71,701 blood donations; 45,515 (63.5%) being voluntary donations with 11,680 (25%) repeat donations were collected during the study period. Donations from schools and colleges contributed a steady 60% of total voluntary whilst radio station blood drives increased contribution from 10 to 27%. Though Muslim population is less than 20%, blood collection was above the 30-donation cost-effectiveness threshold with a repeat donation trend reaching 60%. In contrast Christian worshippers provided donations. Repeat donation trends amongst school donors and radio blood drives were 20% and 70% respectively. Repeat donations rates have been variable amongst different blood donor groups in Kumasi, Ghana. The impact of community leaders in propagating altruism cannot be overemphasized. Programs aiming at motivating replacement donors to be repeat donors should be developed and assessed. Copyright 2009 The International Association for Biologicals. All rights reserved.

    Since the introduction of nucleic acid testing (NAT) for routine blood donor screening, hepatitis C virus (HCV) RNA-only detection rates reported from Poland have been higher than in most other European countries. To examine factors that likely contribute to these window-period donations, we conducted a case-control study among 47 recently HCV-infected blood donors (cases), who gave blood between July 2002 and June 2014, and 141 controls matched by age, sex, and donation dates. Firth-corrected, conditional logistic regression models were fitted to estimate adjusted odds ratios and 95% confidence intervals. Adjusted population-attributable fractions were calculated based on the distribution of exposure among the cases. On multivariate analysis, recent exposures in health care environments not routinely ascertained through predonation questionnaires were strongly associated with recently acquired HCV infection. These exposures included minor medical and dental procedures in the preceding 6 months (adjusted odds ratio, 5.77; 95 % confidence interval, 2.01-18.53). However, based on the population-attributable fraction, more important were behavioral deferrable risks that went unreported at the time of donation, such as high-risk sexual behaviors in the preceding 6 months (population-attributable fraction, 34%) or lifetime histories of drug use (population-attributable fraction, 28%). This study raises questions about the effectiveness of deferral policy in excluding high-risk individuals. In addition, it provides further evidence supporting short, temporal deferrals for small medical procedures and dental treatments in Poland. © 2017 AABB.

    Marked unexplained national variations in incidence rates of kidney cancer have been observed for decades in Europe. To investigate geographic variations at the regional level and identify European regions with high incidence rates of kidney cancer. Regional- and national-level incidence data were extracted from the Cancer Incidence in Five Continents databases, local cancer registry databases, and local published reports. World population age-standardised rates (ASRs) were calculated for the periods 2003-2007 and 1988-1992. Rates by period and sex were compared using map visualisation. During 2003-2007, the highest ASR was found in the Plzen region, Czech Republic (31.4/100,000 person-years in men). Other regions of the Czech Republic had ASRs of 18.6-27.5/100,000 in men, with a tendency for higher rates in regions south of Prague. Surrounding regions, including eastern Germany and regions of Slovakia and Austria, had medium-to-high incidence rates (13.0-16.8/100,000 in men). Three other areas in Europe showed higher incidence rates in men compared with the rest of the continent: Lithuania, Estonia, Latvia, and Belarus (15.0-17.6/100,000); Iceland (13.5/100,000), and northern Italy (up to 16.0/100,000). Similar regional differences were observed among women, with rates approximately half of those observed in men in the same region. In general, these regional geographic variations remained stable over the periods 1988-1992 and 2003-2007, although higher incidence rates were detected in the Baltic countries in 2003-2007. Several European regions show particularly high rates of kidney cancer incidence. Large variations were observed within countries covered by national health-care systems, implying that overdetection is not the major factor. We present regional geographic variations in kidney cancer incidence rates in Europe. We highlight several regions with high incidence rates where further studies should be conducted for cancer control and prevention. Copyright

    Objective: To quantitatively investigate the effect of age on the glomerular filtration rate (GFR) in living-related kidney donors. to analyze the clinical value and the dependence of GFR on age and to provide an objective basis for the selection of the living kidney donor. Methods: One hundred and sixty-one living-related kidney donors were divided into four age groups, namely 20-29 years (n=52), 30-39 years (n=44), 40-49 years (n=38) and ≥50 years (n=27). On the other hand, the total donors were divided into the groups older than 55 years (n=24) and younger than 55 years (n=137). To quantify GFR in all the subjects using the 99 Tc m -diethylenetriamine pentaacetic acid ( 99 Tc m -DTPA) renography according to standard procedure and to evaluate the effects of age on renal function. Results: The total GFR in living-related kidney donors was calculated as (89.55±12.87) ml·min -1 ·(1.73 m 2 ) -1 . The GFR in the first to the four age groups were (88.27±12.29) ml·min -1 ·(1.73 m 2 ) -1 , (91.85±14.51) ml·min -1 ·(1.73 m 2 ) -1 , (98.25±11.26) ml·min -1 ·(1.73 m 2 ) -1 and (88.24±13.20) ml·min -1 ·(1.73 m 2 ) -1 . The difference of GFR were not significant between the four age groups (F=2.09, P=0.10). The GFR in the donors older than 55 years and younger than 55 years were (88.57±13.14) ml·min -1 ·(1.73 m 2 ) -1 and (89.44±10.34) ml·min -1 ·(1.73 m 2 ) -1 , there no significant difference in GFR between the two groups (F=1.31, P=0.25). When relating GFR to age in all the living-related kidney donors, there was no significant correlation (r=-0.033, P=0.69). No serious complications occurred after living kidney transplantation, serum creatinine values and blood urea nitrogen recovered to the normal levels in a short period, hepatic and renal functions were normal. Conclusion: This study indicated that the GFR values were not correlated with the change of age in living-related kidney donors, and the results were helpful for the selection of living

  6. Identification of Strategies to Facilitate Organ Donation among African Americans using the Nominal Group Technique (United States)

    Qu, Haiyan; Shewchuk, Richard; Mannon, Roslyn B.; Gaston, Robert; Segev, Dorry L.; Mannon, Elinor C.; Martin, Michelle Y.


    Background and objectives African Americans are disproportionately affected by ESRD, but few receive a living donor kidney transplant. Surveys assessing attitudes toward donation have shown that African Americans are less likely to express a willingness to donate their own organs. Studies aimed at understanding factors that may facilitate the willingness of African Americans to become organ donors are needed. Design, setting, participants, & measurements A novel formative research method was used (the nominal group technique) to identify and prioritize strategies for facilitating increases in organ donation among church-attending African Americans. Four nominal group technique panel interviews were convened (three community and one clergy). Each community panel represented a distinct local church; the clergy panel represented five distinct faith-based denominations. Before nominal group technique interviews, participants completed a questionnaire that assessed willingness to become a donor; 28 African-American adults (≥19 years old) participated in the study. Results In total, 66.7% of participants identified knowledge- or education-related strategies as most important strategies in facilitating willingness to become an organ donor, a view that was even more pronounced among clergy. Three of four nominal group technique panels rated a knowledge-based strategy as the most important and included strategies, such as information on donor involvement and donation-related risks; 29.6% of participants indicated that they disagreed with deceased donation, and 37% of participants disagreed with living donation. Community participants’ reservations about becoming an organ donor were similar for living (38.1%) and deceased (33.4%) donation; in contrast, clergy participants were more likely to express reservations about living donation (33.3% versus 16.7%). Conclusions These data indicate a greater opposition to living donation compared with donation after one’s death

  8. Just love in live organ donation. (United States)

    Zeiler, Kristin


    Emotionally-related live organ donation is different from almost all other medical treatments in that a family member or, in some countries, a friend contributes with an organ or parts of an organ to the recipient. Furthermore, there is a long-acknowledged but not well-understood gender-imbalance in emotionally-related live kidney donation. This article argues for the benefit of the concept of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The concept of just love is helpful in the analysis of these live organ donations even if no statistical gender-imbalance prevails. It is particularly helpful, however, in the analysis of the gender-imbalance in live kidney donations if these donations are seen as a specific kind of care-work, if care-work is experienced as a labour one should perform out of love and if women still experience stronger pressures to engage in care-work than do men. The aim of the article is to present arguments for the need of just love as an analytic tool in the analysis of emotionally-related live organ donation where the potential donor(s) and the recipient are engaged in a love relation. The aim is also to elaborate two criteria that need to be met in order for love to qualify as just and to highlight certain clinical implications.

  9. Identifying potential kidney donors using social networking web sites. (United States)

    Chang, Alexander; Anderson, Emily E; Turner, Hang T; Shoham, David; Hou, Susan H; Grams, Morgan


    Social networking sites like Facebook may be a powerful tool for increasing rates of live kidney donation. They allow for wide dissemination of information and discussion and could lessen anxiety associated with a face-to-face request for donation. However, sparse data exist on the use of social media for this purpose. We searched Facebook, the most popular social networking site, for publicly available English-language pages seeking kidney donors for a specific individual, abstracting information on the potential recipient, characteristics of the page itself, and whether potential donors were tested. In the 91 pages meeting inclusion criteria, the mean age of potential recipients was 37 (range: 2-69); 88% were US residents. Other posted information included the individual's photograph (76%), blood type (64%), cause of kidney disease (43%), and location (71%). Thirty-two percent of pages reported having potential donors tested, and 10% reported receiving a live-donor kidney transplant. Those reporting donor testing shared more potential recipient characteristics, provided more information about transplantation, and had higher page traffic. Facebook is already being used to identify potential kidney donors. Future studies should focus on how to safely, ethically, and effectively use social networking sites to inform potential donors and potentially expand live kidney donation. © 2013 John Wiley & Sons A/S.

  10. Effect of media presentations on willingness to commit to organ donation. (United States)

    Harel, Inbal; Kogut, Tehila; Pinchas, Meir; Slovic, Paul


    We examine how presentations of organ donation cases in the media may affect people's willingness to sign organ donation commitment cards, donate the organs of a deceased relative, support the transition to an "opt-out" policy, or donate a kidney while alive. We found that providing identifying information about the prospective recipient (whose life was saved by the donation) increased the participants' willingness to commit to organ donation themselves, donate the organs of a deceased relative, or support a transition to an "opt-out" policy. Conversely, identifying the deceased donor tended to induce thoughts of death rather than about saving lives, resulting in fewer participants willing to donate organs or support measures that facilitated organ donation. A study of online news revealed that identification of the donor is significantly more common than identification of the recipient in the coverage of organ donation cases-with possibly adverse effects on the incidence of organ donations.

  11. Study of the infestation rate of the kidney and spleen of domestic ruminants by Linguatula serrata nymphs in Urmia slaughterhouse

    Directory of Open Access Journals (Sweden)

    S Rasouli


    Full Text Available In this study, the prevalence of Linguatula serrata nymphs in kidneys and spleens of 800 domestic ruminants (cattle, buffalo, sheep and goat in different sexes, ages and seasons was investigated. First, the kidneys and spleens were examined macroscopically. Then, a digestion method was also applied. Infestation rate in the spleen of cattle, buffalo, sheep and goat were %0/5, %0, %0/5 and %1/5 respectively. No infestation was found in the kidneys. The results of this study shows that the infestation of domestic ruminants to Linguatula serrat nymphs in different sexes and ages were not significant. Also the infestation rate in different seasons was not significant.

  12. Legal and ethical aspects of organ donation and transplantation

    Directory of Open Access Journals (Sweden)

    Sunil Shroff


    Full Text Available The legislation called the Transplantation of Human Organ Act (THO was passed in India in 1994 to streamline organ donation and transplantation activities. Broadly, the act accepted brain death as a form of death and made the sale of organs a punishable offence. With the acceptance of brain death, it became possible to not only undertake kidney transplantations but also start other solid organ transplants like liver, heart, lungs, and pancreas. Despite the THO legislation, organ commerce and kidney scandals are regularly reported in the Indian media. In most instances, the implementation of the law has been flawed and more often than once its provisions have been abused. Parallel to the living related and unrelated donation program, the deceased donation program has slowly evolved in a few states. In approximately one-third of all liver transplants, the organs have come from the deceased donor program as have all the hearts and pancreas transplants. In these states, a few hospitals along with committed NGOs have kept the momentum of the deceased donor program. The MOHAN Foundation (NGO based in Tamil Nadu and Andhra Pradesh has facilitated 400 of the 1,300 deceased organ transplants performed in the country over the last 14 years. To overcome organ shortage, developed countries are re-looking at the ethics of unrelated programs and there seems to be a move towards making this an acceptable legal alternative. The supply of deceased donors in these countries has peaked and there has been no further increase over the last few years. India is currently having a deceased donation rate of 0.05 to 0.08 per million population. We need to find a solution on how we can utilize the potentially large pool of trauma-related brain deaths for organ donation. This year in the state of Tamil Nadu, the Government has passed seven special orders. These orders are expected to streamline the activity of deceased donors and help increase their numbers. Recently, on

  13. Measurement of Murine Single-Kidney Glomerular Filtration Rate Using Dynamic Contrast-Enhanced MRI. (United States)

    Jiang, Kai; Tang, Hui; Mishra, Prasanna K; Macura, Slobodan I; Lerman, Lilach O


    To develop and validate a method for measuring murine single-kidney glomerular filtration rate (GFR) using dynamic contrast-enhanced MRI (DCE-MRI). This prospective study was approved by the Institutional Animal Care and Use Committee. A fast longitudinal relaxation time (T 1 ) measurement method was implemented to capture gadolinium dynamics (1 s/scan), and a modified two-compartment model was developed to quantify GFR as well as renal perfusion using 16.4T MRI in mice 2 weeks after unilateral renal artery stenosis (RAS, n = 6) or sham (n = 8) surgeries. This approach was validated by comparing model-derived GFR and perfusion to those obtained by fluorescein isothiocyanante (FITC)-inulin clearance and arterial spin labeling (ASL), respectively, using the Pearson's and Spearman's rank correlations and Bland-Altman analysis. The compartmental model provided a good fitting to measured gadolinium dynamics in both normal and RAS kidneys. The proposed DCE-MRI method offered assessment of single-kidney GFR and perfusion, comparable to the FITC-inulin clearance (Pearson's correlation coefficient r = 0.95 and Spearman's correlation coefficient ρ = 0.94, P < 0.0001, and mean difference -7.0 ± 11.0 μL/min) and ASL (r = 0.92 and ρ = 0.84, P < 0.0001, and mean difference 4.4 ± 66.1 mL/100 g/min) methods. The proposed DCE-MRI method may be useful for reliable noninvasive measurements of single-kidney GFR and perfusion in mice.

  14. Organ donation on Web 2.0: content and audience analysis of organ donation videos on YouTube. (United States)

    Tian, Yan


    This study examines the content of and audience response to organ donation videos on YouTube, a Web 2.0 platform, with framing theory. Positive frames were identified in both video content and audience comments. Analysis revealed a reciprocity relationship between media frames and audience frames. Videos covered content categories such as kidney, liver, organ donation registration process, and youth. Videos were favorably rated. No significant differences were found between videos produced by organizations and individuals in the United States and those produced in other countries. The findings provide insight into how new communication technologies are shaping health communication in ways that differ from traditional media. The implications of Web 2.0, characterized by user-generated content and interactivity, for health communication and health campaign practice are discussed.

  15. Pecuniary and Non-Pecuniary Incentives to Increase the Rate of Organ Donations from the Living: A Moral Exploration

    Directory of Open Access Journals (Sweden)

    Michael Y. Barilan


    Full Text Available This paper examines the morality of schemes of payment to live donors/sellers of organs for transplantation. Following empirical and historical evidence, it is argued that consent to sell organs is substantially different from consent to ordinary business transactions and that legalization of exchanges of organs with financial benefits deviates significantly from the scope of liberal toleration and liberal conceptions of human rights. Although altruistic giving is commendable, it is immoral for society to benefit from them without conferring to the donors benefits such as health and nursing insurance for life. Non-alienable and non-fungible benefits of this kind are moral as incentives to organ donation/giving.

  16. The Impact of Latino Values and Cultural Beliefs on Brain Donation: Results of a Pilot Study to Develop Culturally Appropriate Materials and Methods to Increase Rates of Brain Donation in this Under-Studied Patient Group. (United States)

    Bilbrey, Ann Choryan; Humber, Marika B; Plowey, Edward D; Garcia, Iliana; Chennapragada, Lakshmi; Desai, Kanchi; Rosen, Allyson; Askari, Nusha; Gallagher-Thompson, Dolores


    Increasing the number of Latino persons with dementia who consent to brain donation (BD) upon death is an important public health goal that has not yet been realized. This study identified the need for culturally sensitive materials to answer questions and support the decision-making process for the family. Information about existing rates of BD was obtained from the Alzheimer's Disease Centers. Several methods of data collection (query NACC database, contacting Centers, focus groups, online survey, assessing current protocol and materials) were used to give the needed background to create culturally appropriate BD materials. A decision was made that a brochure for undecided enrollees would be beneficial to discuss BD with family members. For those needing further details, a step-by-step handout would provide additional information. Through team collaboration and engagement of others in the community who work with Latinos with dementia, we believe this process allowed us to successfully create culturally appropriate informational materials that address a sensitive topic for Hispanic/Latino families. Brain tissue is needed to further knowledge about underlying biological mechanism of neurodegenerative diseases, however it is a sensitive topic. Materials assist with family discussion and facilitate the family's follow-through with BD.

  17. Estimated glomerular filtration rate is an early biomarker of cardiac surgery-associated acute kidney injury. (United States)

    Candela-Toha, Ángel; Pardo, María Carmen; Pérez, Teresa; Muriel, Alfonso; Zamora, Javier


    and objective Acute kidney injury (AKI) diagnosis is still based on serum creatinine and diuresis. However, increases in creatinine are typically delayed 48h or longer after injury. Our aim was to determine the utility of routine postoperative renal function blood tests, to predict AKI one or 2days in advance in a cohort of cardiac surgery patients. Using a prospective database, we selected a sample of patients who had undergone major cardiac surgery between January 2002 and December 2013. The ability of the parameters to predict AKI was based on Acute Kidney Injury Network serum creatinine criteria. A cohort of 3,962 cases was divided into 2groups of similar size, one being exploratory and the other a validation sample. The exploratory group was used to show primary objectives and the validation group to confirm results. The ability to predict AKI of several kidney function parameters measured in routine postoperative blood tests, was measured with time-dependent ROC curves. The primary endpoint was time from measurement to AKI diagnosis. AKI developed in 610 (30.8%) and 623 (31.4%) patients in the exploratory and validation samples, respectively. Estimated glomerular filtration rate using the MDRD-4 equation showed the best AKI prediction capacity, with values for the AUC ROC curves between 0.700 and 0.946. We obtained different cut-off values for estimated glomerular filtration rate depending on the degree of AKI severity and on the time elapsed between surgery and parameter measurement. Results were confirmed in the validation sample. Postoperative estimated glomerular filtration rate using the MDRD-4 equation showed good ability to predict AKI following cardiac surgery one or 2days in advance.

  18. Does the Pulsatile Preservation Machine Have Any Impact in the Discard Rate of Kidneys From Older Donors After Brain Death? (United States)

    Paredes-Zapata, D; Ruiz-Arranz, A; Rodriguez-Villar, C; Roque-Arda, R; Peri-Cusi, L; Saavedra-Escobar, S; Vizcaino-Elias, F; Garcia-Rodriguez, X; Bohils-Valle, M; Rodriguez-Peña, S; Quijada-Martorell, M; Gonzalez-Rodriguez, J-J; Oppenheimer-Salinas, F; Alcaraz-Asensio, A; Adalia-Bartolome, R


    Donors after brain death (DBD) older than 60 years have become 46.8% of our current activity, with higher risk of renal discard rate (RDR). Assessment of kidney suitability requires complementary strategies: macroscopic evaluation, kidney biopsy score (KBS), and renal hemodynamic evaluation with the Pulsatile Perfusion Machine (PPM). Descriptive, cross-sectional, comparative study of kidneys procured and RDR, comparing 3 time periods: 2000 to June 2004, when only KBS were used; July 2004 to 2008 (introduction of PPM and learning period); and 2009 to 2013 (experienced use of PPM). Transplantation criteria were KBS 70 mL/min. Between 2000 and 2013, a 59.2% reduction in DBD kidneys was observed. However, older kidneys had an increase from 33.5% to 46.8%. The RDR had increased, comparing the first to the third period from 25.4% to 38.3%. However, the RDR was lower when kidneys were evaluated with PPM than those evaluated only with KBS and preserved in cold storage (CS) (21.4% versus 43.7%). There was a significant difference in cold ischemia time, because CS kidney was grafted before PPM. During the third period, more kidneys with KBS ≥4 were assigned to PPM. Notwithstanding the decrease in DBD-procured kidneys and the increase in older kidneys during last period, the use of PPM allowed low DR compared with CS. A bias in the results of PPM could be generated when kidneys with higher KBS were excluded from PPM. The use of KBS only to decide acceptance could preclude the use of an additional tool to evaluate suitability. Copyright © 2015 Elsevier Inc. All rights reserved.

    Extracorporeal membrane oxygenation has become rescue therapy for adults with overwhelming cardiac and/or respiratory failure. Not all patients are saved, creating a new cohort of potential organ donors. This study examines the outcomes of liver and kidney allografts procured from donors on extracorporeal membrane oxygenation (ECMO). A retrospective review was conducted through the local organ procurement organization. Donors on ECMO prior to notification were classified into donation after brain death (DBD) and donation after cardiac death (DCD). We compared short-term outcome data against published standards. Between 1995 and 2012, 97 organs were procured from 41 donors supported on ECMO. There were 68 kidneys donated, 51 were transplanted and 17 discarded. Excluding extended criteria donors, 29 DBD and 13 DCD kidneys were transplanted from donors supported on ECMO. Delayed graft function occurred in 34% of DBD kidneys and 38% of DCD kidneys. Kidney allograft survival at one yr was 93%. Twenty-four livers were procured, nine discarded, and 15 transplanted. Ninety-three percent of liver transplant recipients were alive with graft function at one yr. Donation after brain death kidneys procured from donors on ECMO perform similarly to non-ECMO organs with regard to delayed graft function (DGF), one-yr graft survival and function. Livers from ECMO donors have a higher discard rate than non-ECMO donors, but function similarly at six months and one yr. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Full Text Available Capsule Male aging effects on aneuploidy rates in embryos. Objective Paternal age is associated with decreasing sperm quality; however, it is unknown if it influences chromosomal abnormalities in embryos. The objective of this study is to evaluate if the aneuploidy rates in embryos are affected by advanced paternal age. Methods A total of 286 embryos, obtained from 32 in vitro fertilization/intracytoplasmic sperm injection cycles with donated oocytes in conjunction with preimplantation genetic diagnosis, were allocated according to paternal age in three groups: Group A: ≤39 years (n = 44 embryos; Group B: 40-49 years (n = 154 embryos; and Group C: ≥50 years (n = 88 embryos. Fertilization rates, embryo quality at day 3, blastocyst development, and aneuploidy embryo rates were then compared. Results There was no difference in the seminal parameters (volume, concentration, and motility in the studied groups. Fertilization rate, percentages of zygotes underwent cleavage, and good quality embryos on day 3 were similar between the three evaluated groups. The group of men ≥50 years had significantly more sperm with damaged DNA, low blastocyst development rate, and higher aneuploidy rates in embryos compared to the other two evaluated groups ( P 50 years old.

  1. Expanding the live kidney donor pool: ethical considerations regarding altruistic donors, paired and pooled programs. (United States)

    Patel, Shaneel Rajendra; Chadha, Priyanka; Papalois, Vassilios


    In renal transplant, there is a well-known deficiency in organ supply relative to demand. Live donation provides superior results when compared with deceased donation including a better rate of graft success and fewer immunologic complications. This deficiency in organs leads to significant morbidity and mortality rates. Alternative avenues have been extensively explored that may expand the live donor pool. They include altruistic donation as well as paired and pooled exchange programs. Altruistic donation is a truly selfless act from a donor unknown to the recipient. Kidney paired donation involves 2 incompatible donor-recipient pairs swapping donors to produce compatibility. Pooled donation involves at least 2 pairs, and can take the form of domino chains in which altruistic input sets up a chain of transplants, in which each recipient's incompatible donor makes a donation for the next recipient. Despite application of these various methods, there lie extensive ethical issues surrounding them. Misconceptions frequently occur; for instance, the perceived benefit that donating an organ to a loved one is greater for a related donor than for an altruistic one. Additionally, it is frequently believed that immunologic incompatibility offers coerced donors liberation from surgery, and that overcoming these barriers by introducing exchange programs provides vulnerable donors less protection. This article explores these and other complex ethical issues surrounding the various methods of expanding the donor pool. The authors offer opinions that challenge the ethical issues and attempt to overcome those views that hinder progress in the field.

  4. Living organ donation: the effect of message frame on an altruistic behaviour. (United States)

    McGregor, Lesley M; Ferguson, Eamonn; O'Carroll, Ronan E


    This experimental study investigates the impact of message frame and risk perceptions upon willingness to consider living organ donation. A 2 (gain vs. loss) by 2 (liver vs. kidney) by 2 (involved vs. not involved) between-group study was conducted. Eighty-seven participants completed a questionnaire after reading a vignette designed to invite participants to consider living kidney or liver donation. Within a gain frame scenario, willingness to donate was significantly higher when the risk of donating was lower. The results have important implications for the generalizability of framing theories and the promotion of living organ donation.

  5. Bone Tissue Donation: Tendency and Hurdles. (United States)

    El Hage, S; Dos Santos, M J; de Moraes, E L; de Barros E Silva, L B


    The aim of this study was to identify the percentage of bone tissue donation in a brain death situation and the tendency of donation rate of this tissue in an organ procurement organization in the county of Sao Paulo from 2001 to 2016. It is a retrospective and quantitative study, based on the Organ and Tissue Donation Term of donors who died of brain death between 2001 and 2016. A logistic regression model was applied, and the odds of donation were identified throughout the years, regarding the odds ratio different from zero. Finally, it was measured the accuracy of the odds ratio through the confidence interval. The analysis has shown a significant change on the trend of bone donation (P 1, indicating that the donation rate has increased. However, the percentage of growth is still considered low. The study evidences a growth trend regarding the donation of bone tissue, but the percentage is still too low to adequately meet the demand of patients who need this modality of therapeutic intervention. It is believed that educational campaigns of donation are not emphasizing the donation of tissues for transplantation, which may be directly impacting their consent rates.

  7. Social and cultural aspects of organ donation in Asia. (United States)

    Woo, K T


    In Asian countries, it is more difficult to obtain cadaver kidneys for renal transplantation because of certain socio-cultural beliefs and customs. The issues affecting living related kidney donation are more social than cultural. This is due to the web of family pressures and personal conflicts for both donor and recipient surrounding the donation. Important misconceptions and fears are: fear of death, the belief that removal of organ violates sanctity of decreased, concern about being cut up after death, desire to be buried whole, dislike of idea of kidneys inside another person, wrong concept of brain death, and the idea of donation being against religious conviction. In Singapore, with the introduction of the Human Organ Transplant Act (HOTA) in 1988, the number of cadaveric transplants have increased, including those from the Medical Therapy Act (MTA). HOTA and education have played pivotal roles in bringing about an increased yield of cadaveric kidneys. With the availability of living unrelated donor (LUD) transplants in India, our living related donor (LRD) transplant programme has suffered, because patients would rather buy a kidney from overseas than get a relative to donate one. Patients are also going to China for overseas cadaveric transplants where the kidneys come from executed convicts. People in countries like Hong Kong, Japan and the Philippines share the same Asian tradition of not parting with their organs after death. Muslim countries like Malaysia require the deceased to have earlier pledged his kidneys for donation prior to death before they can be harvested for transplantation at death.

  8. Use of donor sperm in addition to oocyte donation after repeated implantation failure in normozoospermic patients does not improve live birth rates. (United States)

    Blázquez, A; García, D; Rodríguez, A; Vassena, R; Vernaeve, V


    Does switching to donor semen after at least three failed oocyte donation (OD) cycles with the partner normozoospermic semen increase the live birth rate in a subsequent OD cycle? Switching to donor semen after at least three failed OD cycles with the partner normozoospermic semen does not increase the live birth rate. In some patients, a viable pregnancy cannot be achieved after several OD cycles, despite normal diagnostic findings for the couple. The ESHRE Capri Workshop Group indicates that, in order to improve reproductive outcomes, a semen donation can be offered after three failed ICSI cycles. A retrospective cohort analysis of fourth and fifth OD cycles with either the partner's normozoospermic semen (OD) or double-donation cycles (DD), performed between January 2011 and December 2014 in a private fertility center. These couples did not have a known male factor. The study included 228 cycles (159 OD and 69 DD). The fertilization method was ICSI in all cycles and embryos were transferred fresh. Fertilization rates were compared between groups using ANOVA while pregnancy outcomes were compared using Chi-square tests. Effect of DD on pregnancy outcomes was further analyzed using a logistic regression model adjusted for recipient's age and BMI, number of embryos transferred, day of embryo transfer and morphological embryo quality score. There was no difference in live birth rate between the DD and OD groups (38.2 versus 35.8%, P = 0.73), even after adjustment for confounding factors (odds ratio 1.41, 95% confidence interval 0.72, 2.76; P = 0.31). Rates of biochemical pregnancy (52.2 versus 54.1%, P = 0.79), clinical pregnancy (41.2 versus 45.9%, P = 0.51) and ongoing pregnancy (38.2 versus 37.1%, P = 0.87) were not different between the DD and the OD groups, as well as fertilization rate (75.3 versus 75.2%, P = 0.97). The DD and OD groups were comparable at baseline in all demographic and cycle variables analyzed (recipient's BMI, number of

  9. Urological disorders in chronic kidney disease in children cohort: clinical characteristics and estimation of glomerular filtration rate. (United States)

    Dodson, Jennifer L; Jerry-Fluker, Judith V; Ng, Derek K; Moxey-Mims, Marva; Schwartz, George J; Dharnidharka, Vikas R; Warady, Bradley A; Furth, Susan L


    Urological disorders are the most common cause of pediatric chronic kidney disease. We determined the characteristics of children with urological disorders and assessed the agreement between the newly developed bedside glomerular filtration rate estimating formula with measured glomerular filtration rate in 586 patients in the Chronic Kidney Disease in Children study. The Chronic Kidney Disease in Children study is a prospective, observational cohort of children recruited from 48 sites in the United States and Canada. Eligibility requirements include age 1 to 16 years and estimated glomerular filtration rate by original Schwartz formula 30 to 90 ml/min/1.73 m(2). Baseline demographics, clinical variables and glomerular filtration rate were assessed. Bland-Altman analysis was conducted to assess agreement between estimated and measured glomerular filtration rates. Of the 586 participants with at least 1 glomerular filtration rate measurement 348 (59%) had an underlying urological diagnosis (obstructive uropathy in 118, aplastic/hypoplastic/dysplastic kidneys in 104, reflux in 87 and other condition in 39). Among these patients median age was 9 years, duration of chronic kidney disease was 7 years and age at first visit with a urologist was less than 1 year. Of the patients 67% were male, 67% were white and 21% had a low birth weight. Median height was in the 24th percentile. Median glomerular filtration rate as measured by iohexol plasma disappearance was 44.8 ml/min/1.73 m(2). Median glomerular filtration rate as estimated by the Chronic Kidney Disease in Children bedside equation was 44.3 ml/min/1.73 m(2) (bias = -0.5, 95% CI -1.7 to 0.7, p = 0.44). Underlying urological causes of chronic kidney disease were present in 59% of study participants. These children were diagnosed early in life, and many had low birth weight and growth delay. There is good agreement between the newly developed Chronic Kidney Disease in Children estimating equations and measured

    Combination therapy of intravenous immunoglobulin (IVIG) and rituximab showed a good transplant rate in highly sensitized wait-listed patients for deceased donor kidney transplantation (DDKT), but carried the risk of antibody-mediated rejection. The authors investigated the impact of a new combination therapy of bortezomib, IVIG, and rituximab on transplantation rate.This study was a prospective, open-labeled clinical trial. The desensitization regimen consisted of 2 doses of IVIG (2  g/kg), a single dose of rituximab (375  mg/m), and 4 doses of bortezomib (1.3  mg/m). The transplant rate was analyzed. Anti-Human leukocyte antigen (HLA) DRB antibodies were determined by a Luminex solid-phase bead assay at baseline and after 2, 3, and 6 months in the desensitized patients.There were 19 highly sensitized patients who received desensitization and 17 patients in the control group. Baseline values of class I and II panel reactive antibody (%, peak mean fluorescence intensity) were 83  ±  16.0 (14952  ±  5820) and 63  ±  36.0 (10321  ±  7421), respectively. Deceased donor kidney transplantation was successfully performed in 8 patients (42.1%) in the desensitization group versus 4 (23.5%) in the control group. Multivariate time-varying covariate Cox regression analysis showed that desensitization increased the probability of DDKT (hazard ratio, 46.895; 95% confidence interval, 3.468-634.132; P = 0.004). Desensitization decreased mean fluorescence intensity values of class I panel reactive antibody by 15.5% (20.8%) at 2 months. In addition, a liberal mismatch strategy in post hoc analysis increased the benefit of desensitization in donor-specific antibody reduction. Desensitization was well tolerated, and acute rejection occurred only in the control group.In conclusion, a desensitization protocol using bortezomib, high-dose IVIG, and rituximab increased the DDKT rate in highly sensitized, wait-listed patients.

    Full Text Available The success of a pediatric kidney transplantation program can only be judged by reviewing its results. We aim to audit our short-term outcome of pediatric kidney transplantation at the King Fahad Specialist Hospital-Dammam. A retrospective chart review was performed to collect data about recipient demographics, etiology of end-stage kidney disease, type of dialysis, type of donor and outcome. Between September 2008 and April 2012, 35 pediatric kidney trans-plantations (<16 year were performed of a total of 246 kidney transplants (14.2%. The mean age was 8.1 years, with a mean weight of 23.3 kg, and there were 21 (60% boys in the study. Kidney dysplasia/hypoplasia was the most common etiology (51.4%. Pre-emptive kidney transplantation was performed in six (17% patients. Peritoneal dialysis was the most common mode of dialysis [24 (69% children]. Living donation was the source of kidney allografts in 13 (37% cases. During a mean follow-up of 1.5 years, one patient died and one graft was lost due to kidney vein thrombosis. The one year patient and graft survival rates were 97% and 94%, respectively. Efforts should now be focused on achieving optimal long-term results. There is also a need to encourage pre-emptive transplantation and living donation in this population.

  16. Understanding the pros and cons of organ donation decision-making: Decisional balance and expressing donation intentions among African Americans. (United States)

    Flemming, Shauna St Clair; Redmond, Nakeva; Williamson, Dana Hz; Thompson, Nancy J; Perryman, Jennie P; Patzer, Rachel E; Arriola, Kimberly Jacob


    Increasing public commitment to organ donation is critical to improving donor kidney availability for end-stage renal disease patients desiring transplant. This study surveyed ( N = 1339) African Americans, measuring perceived pros relative to cons of organ donation, to evaluate an existing Transtheoretical Model decisional balance scale and associations between decisional balance and expressing donation intentions. Findings supported the existing scale structure. More positive decisional balance ratios were associated with 1.76 times the odds of expressing intentions (95% confidence interval = 1.52-2.04). Pros were more strongly linked to donation intentions than cons. Greater understanding of organ donation decision-making is valuable for informing interventions that encourage donation.

  20. Cost-effectiveness of policies aimed at increasing organ donation: the case of Chile. (United States)

    Domínguez, J; Harrison, R; Atal, R; Larraín, L


    In this article we present an economic evaluation of policies aimed at increasing deceased organ donation in Chile, a developing country that has low donation rates; it had 5.4 donors per million people (pmp) in 2010. Expert opinions of leading participants in donation and transplantation were analyzed, resulting in a set of local policies aimed at increasing donation rates. Using previous results of reported cost savings of increasing kidney transplantation in Chile, we estimated the net benefits of these policies, as a function of additional donors. The main problem of the Chilean system seems to be the low capability to identify potential donors and a deficit in intensive care unit (ICU) beds. Among considered policies central to increase donation are the following: increasing human and capital resources dedicated to identifying potential donors, providing ICU beds from private centers, and developing an online information system that facilitates procurement coordination and the evaluation of performance at each hospital. Our results show that there is a linear relationship between cost savings and incremental donors pmp. For example, if these policies are capable of elevating donation rates in Chile by 6 donors pmp net estimated cost savings are approximately US $1.9 million. Likewise, considering the effect on patients' quality of life, savings would amount to around $15.0 million dollars per year. Our estimates suggest that these policies have a large cost-saving potential. In fact, considering implementation costs, cost reduction is positive after 4 additional donors pmp, and increasing afterward. Copyright © 2013 Elsevier Inc. All rights reserved.

  2. Phosphorus-31 NMR magnetization transfer measurements of metabolic reaction rates in the rat heart and kidney in vivo

    International Nuclear Information System (INIS)

    Koretsky, A.P.


    31 P NMR is a unique tool to study bioenergetics in living cells. The application of magnetization transfer techniques to the measurement of steady-state enzyme reaction rates provides a new approach to understanding the regulation of high energy phosphate metabolism. This dissertation is concerned with the measurement of the rates of ATP synthesis in the rat kidney and of the creatine kinase catalyzed reaction in the rat heart in situ. The theoretical considerations of applying magnetization transfer techniques to intact organs are discussed with emphasis on the problems associated with multiple exchange reactions and compartmentation of reactants. Experimental measurements of the ATP synthesis rate were compared to whole kidney oxygen consumption and Na + reabsorption rates to derive ATP/O values. The problems associated with ATP synthesis rate measurements in kidney, e.g. the heterogeneity of the inorganic phosphate resonance, are discussed and experiments to overcome these problems proposed. In heart, the forward rate through creatine kinase was measured to be larger than the reverse rate. To account for the difference in forward and reverse rates a model is proposed based on the compartmentation of a small pool of ATP

  3. Outcomes of pregnancies achieved by double gamete donation: A comparison with pregnancies obtained by oocyte donation alone. (United States)

    Women increasingly resort to oocyte donation to become pregnant. The high risk of preeclampsia found in oocyte donation pregnancies and the separate risk of preeclampsia associated with sperm donation may be cumulative in double donation pregnancies. We aimed to study the obstetrical and perinatal outcomes of pregnancies obtained by double donation (both oocyte and sperm) in comparison with those obtained by oocyte donation alone (oocyte donation and partner's sperm). This cohort study included all women aged 43 and older who became pregnant after oocyte donation and gave birth between 2010 and 2016 in a tertiary maternity center. Primary outcomes were preeclampsia and hypertensive gestational disorders. Secondary outcomes were gestational diabetes, placental abnormalities, postpartum hemorrhage, perinatal death, and preterm delivery. We used univariate and multivariate analysis to compare IVF with double donation and IVF with oocyte donation alone for obstetric and perinatal outcomes. 247 women, 53 with double donations and 194 with oocyte donations alone, gave birth to 339 children. We observed no significant differences between groups for any obstetric or perinatal complications, except for the risk of gestational diabetes, which was more frequent in women with double donations compared with oocyte donation alone (26.4% vs. 12.9%, P = 0.02) and remained significant after adjustment (aOR = 2.80 95%CI[1.26-6.17]). Rates of gestational hypertension and preeclampsia were high, but similar between groups (20.7% vs. 26.3%, P = 0.41, and 18.9% vs. 17.5%, P = 0.82). Women undergoing oocyte donation should be fully informed of its high rates of obstetric and perinatal risks. However, except for a higher observed risk of gestational diabetes, double donation does not appear to be associated with a higher risk of complications than oocyte donation alone.

    Full Text Available Aim. To carry out monitoring of the organization and development of organ donation and transplantation in the Russian Federation according to 2014. Materials and methods. Questioning of heads of all the centers of transplantation is carried out. The comparative analysis of the obtained data in dynamics of years, between certain regions of the Russian Federation, the transplantation centers, and also with data of the international registers is made. Results. According to the Register in 2014 in the Russian Federation functioned 36 centers of kidney transplantation, 14 centers of liver transplantation and 9 centers of heart transplantation. The waiting list of kidney transplantation in 2014 included 4636 potential recipients that makes 16% of total number of the patients 29 000 receiving dialysis. The rate of donor activity in 2014 made 3.2 per million population (pmp. Efficiency of donor programs in 2014 continued to increase: the share of effective donors after brain death in 2014 increased to 77.2%, the share of multiorgan explantation made 50.5%, average number of organs received from one effective donor made 2.6. In 2014 the rate of kidney transplantation made 7.0 pmp, the rate of liver transplantation made 2.1 pmp and the rate of heart transplantation made 1.1 pmp. In the Russian Federation the number of transplantations of liver and heart continues to increase. The significant contribution to development of the organ donation and transplantation brings the Moscow region in which 11 centers of transplantation function and nearly a half from all kidney transplantations and more than 65% of all liver and heart transplantations are carried out. Conclusion. In theRussian Federation the potential for further development of the transplantology remains. In particular, at the expense of increase in the efficiency of regional donation programs, introduction of technologies, expansion of the practices of multiorgan donation and transplantations of

    Organ donation is the most important stage for organ transplant. Studies reveal that attitudes of families of brain-dead patients toward donation play a significant role in their decision. We hypothesized that supporting family awareness about the meaning of organ donation, including saving lives while losing a loved one, combined with being informed about brain death and the donation process must be maintained by intensive care unit physicians through standardized interviews and questionnaires to increase the donation rate. We retrospectively evaluated the final decisions of families of 52 brain-dead donors treated at our institution between 2014 and 2017. Data underwent descriptive analyses. The standard interview content was generated after literature search results were reviewed by the authors. Previously, we examined the impact of standardized interviews done by intensive care unit physicians with relatives of potential brain-dead donors regarding decisions to donate or reasons for refusing organ donation. After termination of that study, interviews were done according to the intensivist's orientation, resulting in significantly decreased donation rates. Standardized interviews were then started again, resulting in increased donation rates. Of 17 families who participated in standardized interviews, 5 families (29.4%) agreed to donate organs of their brain-dead relatives. In the other group of families, intensivists governed informing the families of donation without standardized interviews. In this group of 35 families, 5 families (14.3%) approved organ donation. The decision regarding whether to agree to organ donation was statistically different between the 2 family groups (P donation process resulted in an increased rate of organ donation compared with routine protocols.

  7. The impact of pre-intervention rate of kidney function change on the assessment of CKD progression. (United States)

    Fassett, Robert G; Geraghty, Dominic P; Coombes, Jeff S


    Without a run-in phase, chronic kidney disease (CKD) patients enrolled in clinical trials may not be identified as having progressive disease. The aim of this analysis was to quantify the effects of a run-in phase on kidney function outcome in CKD patients enrolled in the Lipid Lowering and Onset of Renal Disease (LORD) trial. The LORD trial assessed the effects of atorvastatin on the rate of change in the estimated glomerular filtration rate (eGFR) and included patients with serum creatinine 120 μmol/l. In this post hoc analysis, we assessed eGFR change during the 12-month period prior to enrolment, the 3-month run-in phase and the first 12-month period of the trial. Eighty of the original 132 patients (where retrospective data were available) were included. The rate of eGFR change during each period was compared. Overall kidney function decreased during the 12 months prior to enrolment by (mean, SD) 0.39 ± 0.98 ml/min/1.73 m(2)/month, improved during the 3-month run-in phase by 0.48 ± 2.90 ml/min/1.73 m(2)/month and decreased during the first 12 months of the trial by 0.15 ± 0.57 ml/min/1.73 m(2)/month. However, only 39 % of patients had declining eGFR during the 12 months prior, 19 % in the 3-month run-in and 42 % during the first 12-month study phase. Most patients (>60 %) entering this clinical trial had stable or improving kidney function. Enrolment was associated with further improved kidney function, which may have been due to 'regression to the mean' or to the Hawthorne effect. Investigators should include a run-in period to establish the presence of eGFR decline to use as an inclusion criterion in clinical trials assessing this measure of CKD progression.

  10. The Global Role of Kidney Transplantation

    Directory of Open Access Journals (Sweden)

    Guillermo Garcia Garcia


    Full Text Available World Kidney Day on March 8 th 2012 provides a chance to reflect on the success of kidney transplantation as a therapy for end stage kidney disease that surpasses dialysis treatments both for the quality and quantity of life that it provides and for its cost effectiveness. Anything that is both cheaper and better, but is not actually the dominant therapy, must have other drawbacks that prevent replacement of all dialysis treatment by transplantation. The barriers to universal transplantation as the therapy for end stage kidney disease include the economic limitations which, in some countries place transplantation, appropriately, at a lower priority than public health fundamentals such as clean water, sanitation and vaccination. Even in high income countries the technical challenges of surgery and the consequences of immunosuppression restrict the number of suitable recipients, but the major finite restrictions on kidney transplantation rates are the shortage of donated organs and the limited medical, surgical and nursing workforces with the required expertise. These problems have solutions which involve the full range of societal, professional, governmental and political environments. World Kidney Day is a call to deliver transplantation therapy to the one million people a year who have a right to benefit.

    The impact of presumed consent on donation rates has been widely debated. In June 2013 Greece adopted a 'soft' presumed consent law for organ and tissue donation, where relatives' approval is sought prior to organ removal. To report on the knowledge, attitudes and concerns of undergraduate students, enrolled in three health science disciplines, in regards to organ donation and presumed consent. Undergraduate junior and senior health science students [medical (MS), nursing (NS) and medical laboratory students (MLS)] were recruited from higher education settings in Thessaly, Greece. Dichotomous questions, previously used, were adopted to assess knowledge, attitudes and concerns towards organ donation, together with questions regarding the recent presumed consent legislation. Three hundred seventy-one out of 510 students participated in the study (response rate: 72.7%). Only 3.6% of NS, 8.7% of MS and 3.2% of MLS carried a donor card. Although over 78% in all groups knew that it was possible to leave kidneys for transplant after death, only 10% to 39% considered themselves well-informed. NS were more likely to consider opting-out (21.5%), followed by MLS (17.9%) and MS (10.9%). Respondents were more likely to refuse organ removal upon death when expressing one of the following views: a) opposing a system making it lawful to take kidneys from an adult who has just died, unless forbidden while alive [Odds ratio (OR) 95% Confidence Interval (CI): 2.96 (1.48-5.93), p=0.002], b) worrying about their kidneys being removed after death [OR, 95% CI: 3.37 (1.75-6.49), p=students, soon to become healthcare professionals, demonstrated limited awareness in regards to the newly reformed organ donation system. Identified knowledge deficits and concerns could have far-reaching implications in terms of conveying a clear message and shaping the public's stand.

    Introduction: The kidneys are the dose-limiting organs in some radionuclide therapy regimens. However, the biological impact of internal exposure from radionuclides is still not fully understood. The aim of this study was to examine the effects of dose rate and time after i.v. injection of 177 LuCl 3 on changes in transcriptional patterns in mouse kidney tissue. Methods: To investigate the effect of dose rate, female Balb/c nude mice were i.v. injected with 11, 5.6, 1.6, 0.8, 0.30, and 0 MBq of 177 LuCl 3 , and killed at 3, 6, 24, 48, 168, and 24 hours after injection, respectively. Furthermore, the effect of time after onset of exposure was analysed using mice injected with 0.26, 2.4, and 8.2 MBq of 177 LuCl 3 , and killed at 45, 90, and 140 days after injection. Global transcription patterns of irradiated kidney cortex and medulla were assessed and enriched biological processes were determined from the regulated gene sets using Gene Ontology terms. Results: The average dose rates investigated were 1.6, 0.84, 0.23, 0.11 and 0.028 mGy/min, with an absorbed dose of 0.3 Gy. At 45, 90 and 140 days, the absorbed doses were estimated to 0.3, 3, and 10 Gy. In general, the number of differentially regulated transcripts increased with time after injection, and decreased with absorbed dose for both kidney cortex and medulla. Differentially regulated transcripts were predominantly involved in metabolic and stress response-related processes dependent on dose rate, as well as transcripts associated with metabolic and cellular integrity at later time points. Conclusion: The observed transcriptional response in kidney tissue was diverse due to difference in absorbed dose, dose rate and time after exposure. Nevertheless, several transcripts were significantly regulated in all groups despite differences in exposure parameters, which may indicate potential biomarkers for exposure of kidney tissue

    In this study, we aimed to evaluate, the efficacy of surgical methods and the factors affecting the residual stone rate by scrutinizing retrospectively the patients who had undergone renal stone surgery. Records of 109 cases of kidney stones who had been surgically treated between January 2010, and July 2013 were reviewed. Patients were divided into three groups in terms of surgical treatment; open stone surgery, percutaneous nephrolithotomy (PNL) and retrograde intrarenal surgery (RIRS). Patients' history, physical examination, biochemical and radiological images and operative and postoperative data were recorded. The patients had undergone PNL (n=74; 67.9%), RIRS (n=22;20.2%), and open renal surgery (n=13; 11.9%). The mean and median ages of the patients were 46±9, 41 (21-75) and, 42 (23-67) years, respectively. The mean stone burden was 2.6±0.7 cm(2) in the PNL, 1.4±0.1 cm(2) in the RIRS, and 3.1±0.9 cm(2) in the open surgery groups. The mean operative times were 126±24 min in the PNL group, 72±12 min in the RIRS group and 82±22 min in the open surgery group. The duration of hospitalisation was 3.1±0.2 days, 1.2±0.3 days and 3.4±1.1 days respectively. While the RIRS group did not need blood transfusion, in the PNL group blood transfusions were given in the PNL (n=18), and open surgery (n=2) groups. Residual stones were detected in the PNL (n=22), open surgery (n=2), and RIRS (n=5) groups. PNL and RIRS have been seen as safe and effective methods in our self application too. However, it should not be forgotten that as a basical method, open surgery may be needed in cases of necessity.

  14. Transcutaneous glomerular filtration rate measurement in a canine animal model of chronic kidney disease. (United States)

    Quantitative assessment of renal function by measurement of glomerular filtration rate (GFR) is an important part of safety and efficacy evaluation in preclinical drug development. Existing methods are often time consuming, imprecise and associated with animal burden. Here we describe the comparison between GFR determinations with sinistrin (PS-GFR) and fluorescence-labelled sinistrin-application and its transcutaneous detection (TD-GFR) in a large animal model of chronic kidney disease (CKD). TD-GFR measurements compared to a standard method using i.v. sinistrin were performed in a canine model. Animals were treated with one-sided renal wrapping (RW) followed by renal artery occlusion (RO). Biomarker and remote hemodynamic measurements were performed. Plasma sinistrin in comparison to transcutaneous derived GFR data were determined during healthy conditions, after RW and RW+RO. RW alone did not led to any significant changes in renal function, neither with PS-GFR nor TD-GFR. Additional RO showed a rise in blood pressure (+68.0mmHg), plasma urea (+28.8mmol/l), creatinine (+224,4μmol/l) and symmetric dimethylarginine (SDMA™; +12.6μg/dl). Plasma sinistrin derived data confirmed the expected drop (-44.7%, p<0.0001) in GFR. The calculated transcutaneous determined Fluorescein Isothiocyanate (FITC)-sinistrin GFR showed no differences to plasma sinistrin GFR at all times. Both methods were equaly sensitive to diagnose renal dysfunction in the affected animals. Renal function assessment using TD-GFR is a valid method to improve preclinical drug discovery and development. Furthermore, TD-GFR method offers advantages in terms of reduced need for blood sampling and thus decreasing animal burden compared to standard procedures. Copyright © 2017 Elsevier Inc.

    Objective: Glomerular filtration rate (GFR) is one of the valuable indictors of allograft status after kidney transplantation. The feasibility of an easy measurement of GFR by dynamic renal imaging (dGFR) was assessed in comparison to a classical dual plasma sample method (tGFR) in the current study for evaluating the function of grafting kidney. Methods: In 73 patients of kidney transplantation, both dynamic renal imaging and dual sample GFR measurement were undertaken after 99 Tc m -DTPA injection. The correlation between dGFR and tGFR, both being standardized according to surface area, was analyzed and the linear regression equation was obtained. Results: The mean dGFR was slightly lower than that of tGFR (t=-2.010, P<0.05). The dGFR correlated significantly with tGFR (r=0.759, P< 0.01). The linear regression equation was tGFR=0.6455 x dGFR + 25.514. Conclusion: The dGFR correlated well with tGFR and they were accurate in evaluating the filtration function of transplanted kidney.

Papers known to the authors were included, as were scientific statements. Articles were chosen based on the judgment of the authors.Results: Drug-dosing decisions should be based on the method used in the published studies and package labeling that have been determined to be safe, which is most often the Cockcroft–Gault formula unadjusted for body weight. Although Modification of Diet in Renal Disease is more commonly used in practice for staging, the CKD–Epidemiology Collaboration (CKD–EPI equation is the most accurate formula for estimating the CKD staging, especially at higher GFR values. Automated HITs offer a solution to the complexity of determining which equation to use for a given clinical scenario. HITs can educate providers on which formula to use and how to apply the formula in a given clinical situation, ultimately improving appropriate medication and medical management in CKD patients.Conclusion: Appropriate estimation of GFR is key to optimal health outcomes. HITs assist clinicians in both choosing the most appropriate GFR estimation formula and in applying the results of the GFR estimation in practice. Key limitations of the

  2. Exploring opinions and beliefs about cord blood donation among Hispanic and non-Hispanic black women. (United States)

    Rucinski, Dianne; Jones, Risé; Reyes, Brenda; Tidwell, Lawon; Phillips, RoiAnn; Delves, Denise


    Despite higher birth rates among non-Hispanic blacks and Hispanics, the availability of umbilical cord blood from these groups is lower due to lower donation rates than that of non-Hispanic whites. Similar racial and ethnic disparities in donation rates have been found for blood and organ donation. This study is among the first to explore beliefs and attitudes toward umbilical cord blood donation among Hispanic and non-Hispanic black women. Five focus groups composed of Hispanic and non-Hispanic black women were conducted to explore how women conceptualize information needs about umbilical cord blood donation and from whom women want to receive information about donation. Participants were adult women who had given birth within the past year or were pregnant. Lack of basic information regarding umbilical cord blood, its harvesting and use, and the steps and conditions necessary to donate were primary barriers to donation. Women expressed confusion over the differences between "donation" and "banking." The social value of donation was explicitly weighed in terms of the cost of the donation effort. Doctors were viewed as critical sources for information about donation, although women expressed skepticism about doctors' ability to convey sufficient information during short office visits. Efforts to increase donation rates among Hispanic and non-Hispanic black women should include information about both the technical aspects and the social value of donation. The specific terms "umbilical" and "donation" should be used consistently to prevent misunderstanding. Information should be provided by physicians with follow-up by other health providers.

  4. Uptake and release of glucose by the human kidney. Postabsorptive rates and responses to epinephrine. (United States)

    Stumvoll, M; Chintalapudi, U; Perriello, G; Welle, S; Gutierrez, O; Gerich, J


    Despite ample evidence that the kidney can both produce and use appreciable amounts of glucose, the human kidney is generally regarded as playing a minor role in glucose homeostasis. This view is based on measurements of arteriorenal vein glucose concentrations indicating little or no net release of glucose. However, inferences from net balance measurements do not take into consideration the simultaneous release and uptake of glucose by the kidney. Therefore, to assess the contribution of release and uptake of glucose by the human kidney to overall entry and removal of plasma glucose, we used a combination of balance and isotope techniques to measure renal glucose net balance, fractional extraction, uptake and release as well as overall plasma glucose appearance and disposal in 10 normal volunteers under basal postabsorptive conditions and during a 3-h epinephrine infusion. In the basal postabsorptive state, there was small but significant net output of glucose by the kidney (66 +/- 22 mumol.min-1, P = 0.016). However, since renal glucose fractional extraction averaged 2.9 +/- 0.3%, there was considerable renal glucose uptake (2.3 +/- 0.2 which accounted for 20.2 +/- 1.7% of systemic glucose disposal (11.4 +/- 0.5 Renal glucose release (3.2 +/- 0.2 accounted for 27.8 +/- 2.1% of systemic glucose appearance (11.4 +/- 0.5 Epinephrine infusion, which increased plasma epinephrine to levels observed during hypoglycemia (3722 +/- 453 pmol/liter) increased renal glucose release nearly twofold (5.2 +/- 0.5 vs 2.8 +/- 0.1, P = 0.01) so that at the end of the infusion, renal glucose release accounted for 40.3 +/- 5.5% of systemic glucose appearance and essentially all of the increase in systemic glucose appearance. These observations suggest an important role for the human kidney in glucose homeostasis.

  5. First UK case report of kidney transplantation from an HIV-infected deceased donor to two HIV-infected recipients. (United States)

    Nolan, Eileen; Karydis, Nikolaos; Drage, Martin; Hilton, Rachel


    Kidney transplantation is now considered the treatment of choice for many human immunodeficiency virus (HIV)-infected patients with end-stage renal disease (ESRD). Graft survival rates using HIV-negative donors and carefully selected HIV-positive ESRD patients are similar to those observed in HIV-uninfected kidney transplant recipients. To address the relative shortfall in donated organs it has been proposed that organs from HIV-infected deceased donors might be allocated to HIV-infected patients on the transplant waiting list. Preliminary experience in South Africa reports promising short-term outcomes in a small number of HIV-infected recipients of kidney transplants from HIV-infected donors. We sought to replicate this experience in the UK by accepting kidney offers from HIV infected deceased donors for patients with HIV-infection on the kidney transplant waiting list. Here we report the UK's first cases of kidney transplantation between HIV-positive donors and recipients.

    It has been suggested that blood donors with hereditary hemochromatosis may pose an increased infectious disease risk and adversely affect recipient outcomes. This study compares the infectious disease risk of whole blood (WB) donors enrolled as therapeutic (T) donors to voluntary WB donors to evaluate the safety of blood products provided by the T donors. This was a retrospective cohort study of all WB donations at the Australian Red Cross Blood Service who donated between January 1, 2011, and December 31, 2013, comparing a yearly mean of 11,789 T donors with 107,773 total donations and a yearly mean of 468,889 voluntary WB donors with 2,584,705 total donations. We compared postdonation notification of infectious illnesses, bacterial contamination screening results, and positive tests for blood borne viruses in T and WB donors. Rates of transfusion-transmissible infections in donations destined for component manufacture were significantly lower in therapeutic donations compared to voluntary donations (8.4 vs. 21.6 per 100,000 donations). Bacterial contamination (43.0 vs. 45.9 per 100,000 donations) and postdonation illness reporting (136.2 vs. 110.8 per 100,000 donations) were similar in both cohorts. The Australian therapeutic venisection program enables T donors to provide a safe and acceptable source of donated WB that has a low infectious disease risk profile. © 2016 AABB.

  7. Health Insurance Trends in United States Living Kidney Donors (2004 to 2015). (United States)

    Rodrigue, J R; Fleishman, A


    Some transplant programs consider the lack of health insurance as a contraindication to living kidney donation. Still, prior studies have shown that many adults are uninsured at time of donation. We extend the study of donor health insurance status over a longer time period and examine associations between insurance status and relevant sociodemographic and health characteristics. We queried the United Network for Organ Sharing/Organ Procurement and Transplantation Network registry for all living kidney donors (LKDs) between July 2004 and July 2015. Of the 53 724 LKDs with known health insurance status, 8306 (16%) were uninsured at the time of donation. Younger (18 to 34 years old), male, minority, unemployed, less educated, unmarried LKDs and those who were smokers and normotensive were more likely to not have health insurance at the time of donation. Compared to those with no health risk factors (i.e. obesity, smoking, hypertension, estimated glomerular filtration rate health risk factors at the time of donation were more likely to be uninsured (p health risk factors, blacks (28%) and Hispanics (27%) had higher likelihood of being uninsured compared to whites (19%; p health insurance benefits to all previous and future LKDs. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  8. Knowledge and ethical perception regarding organ donation among medical students (United States)


    Background To determine the knowledge and ethical perception regarding organ donation amongst medical students in Karachi- Pakistan. Methods Data of this cross sectional study was collected by self administered questionnaire from MBBS students of Ziauddin University from 2010 to 2011. Sample size of 158 (83 First years and 75 Fourth years) were selected by convenient sampling and those students who were present and gave consent were included in the study. The data was analyzed by SPSS version 20. Results A total of 158 participants from Ziauddin Medical University filled out the questionnaire out of which 83(52.5%) were first years and 75(47.5%) were fourth year medical students. Mean age of sample was 20 ± 1.7. Majority of students were aware about organ donation with print and electronic media as the main source of information. 81.6% agreed that it was ethically correct to donate an organ. In the students’ opinion, most commonly donated organs and tissues were kidney, cornea, blood and platelet. Ideal candidates for donating organ were parents (81%). Regarding list of options for preference to receive an organ, most of the students agreed on young age group patients and persons with family. Willingness to donate was significantly associated with knowledge of allowance of organ donation in religion (P=0.000). Conclusion Both 1st year and 4th year students are aware of Organ Donation, but there is a significant lack of knowledge regarding the topic. PMID:24070261

  9. Compensatory changes in the function of the remaining kidney immediately after unilateral nephrectomy in sheep

    International Nuclear Information System (INIS)

    Ziada, G.; Khalil, M.; Youseif, H.


    Live kidney donation is an established form of organ donation but carries the risk of an unnecessary surgery in a normal individual for the benefit of the recipient. Despite a number of recent studies on the renal function of long-term kidney donors, little attention has been paid to the damaging effects of compensatory hyper-filtration on renal tubular cells immediately after donor nephrectomy. The present study therefore aimed to examine the immediate changes in renal function of the remaining kidney using a sheep model of unilateral nephrectomy. We used the gamma camera-based method to measure the glomerular filtration rate and the tubular excretion values after simultaneous injection of 99m Tc-diethylene triamine pentaacetic acid and 131 I-ortho-iodohippurate tracers. Compared were the differences in the functions between the remaining left kidney immediately after clamping the right renal pedicle and the baseline values that were measured one week before unilateral nephrectomy. After radionuclide data acquisition was completed, the right kidney was removed. The mean glomerular filtration rate (GFR) increased by 52.3% from the baseline values (29.5±2.7 to 45.0±6.7 ml/min; n=40, p<0.001), while the mean effective renal plasma flow (ERPF) increased by 40% (225.5±27.8 to 357.8±38.94 ml/min; p<0.001), respectively. Mean filtration fraction was increased from 0.117 to 0.127 immediately after nephrectomy (p<0.001). We conclude that after unilateral nephrectomy the remaining kidney immediately compensates for the loss of a donated kidney by increasing glomerular filtration rate and effective renal plasma flow.

    Patients with chronic kidney disease and severely decreased glomerular filtration rate (GFR) are at high risk for kidney failure, cardiovascular disease (CVD) and death. Accurate estimates of risk and timing of these clinical outcomes could guide patient counseling and therapy. Therefore, we developed models using data of 264,296 individuals in 30 countries participating in the international Chronic Kidney Disease Prognosis Consortium with estimated GFR (eGFR)s under 30 ml/min/1.73m 2 . Median participant eGFR and urine albumin-to-creatinine ratio were 24 ml/min/1.73m 2 and 168 mg/g, respectively. Using competing-risk regression, random-effect meta-analysis, and Markov processes with Monte Carlo simulations, we developed two- and four-year models of the probability and timing of kidney failure requiring kidney replacement therapy (KRT), a non-fatal CVD event, and death according to age, sex, race, eGFR, albumin-to-creatinine ratio, systolic blood pressure, smoking status, diabetes mellitus, and history of CVD. Hypothetically applied to a 60-year-old white male with a history of CVD, a systolic blood pressure of 140 mmHg, an eGFR of 25 ml/min/1.73m 2 and a urine albumin-to-creatinine ratio of 1000 mg/g, the four-year model predicted a 17% chance of survival after KRT, a 17% chance of survival after a CVD event, a 4% chance of survival after both, and a 28% chance of death (9% as a first event, and 19% after another CVD event or KRT). Risk predictions for KRT showed good overall agreement with the published kidney failure risk equation, and both models were well calibrated with observed risk. Thus, commonly-measured clinical characteristics can predict the timing and occurrence of clinical outcomes in patients with severely decreased GFR.

    Screening of living kidney donors may require scintigraphy to split glomerular filtration rate (GFR). To determine the usefulness of computed tomography (CT) to split GFR, we compared scintigraphy-split GFR to CT-split GFR. We evaluated CT-split GFR as a screening test to detect scintigraphy-split GFR lower than 40 mL/min/1.73 m{sup 2}/kidney. This was a monocentric retrospective study on 346 potential living donors who had GFR measurement, renal scintigraphy, and CT. We predicted GFR for each kidney by splitting GFR using the following formula: Volume-split GFR for a given kidney = measured GFR*[volume of this kidney/(volume of this kidney + volume of the opposite kidney)]. The same formula was used for length-split GFR. We compared length- and volume-split GFR to scintigraphy-split GFR at donation and with a 4-year follow-up. A better correlation was observed between length-split GFR and scintigraphy-split GFR (r = 0.92) than between volume-split GFR and scintigraphy-split GFR (r = 0.89). A length-split GFR threshold of 45 mL/min/1.73 m{sup 2}/kidney had a sensitivity of 100 % and a specificity of 75 % to detect scintigraphy-split GFR less than 40 mL/min/1.73 m{sup 2}/kidney. Both techniques with their respective thresholds detected living donors with similar eGFR evolution during follow-up. Length-split GFR can be used to detect patients requiring scintigraphy. (orig.)

    In 1998 in the Centro de Investigaciones Medico Quirurgicas the Transplant Coordination Office (TCO) was created, with the aim to organize a system to support a hepatic transplantation program. This organization, which changed the transplantation-donation process not only in our center but in the whole country, is described in this article. The files of donors generated in our hospital were studied together with the transplant coordination records, from 1999 till the first half of 2002. In the period studied, 21 potential donors were diagnosed with brain death, yielding a donation rate of 71.4%. Brain death was most frequently caused by vascular brain disease; however, in the realized donor group, the cranioencephalic trauma predominated. The typical donor was a man of average age 39.2 years (range, 18-86 years). Among the potential donors, 24% were excluded based on medical criteria, and 5% due to family objections. Forty liver transplantation were performed in 36 patients including 1 liver-kidney simultaneous procedure. The principal etiologies for transplant included hepatitis C virus cirrhosis, 22%; alcoholic, 19%; and acute hepatic failure, 13%. Kidney transplantations were performed in 70 patients, including 41 from cadaveric donors (53.6%) and 29 from living related donors (41.4%). In 2001, a pancreas-kidney transplantation program was started. The creation of the TCO has been of paramount importance to optimize transplantation program functions.

    We evaluated the factors affecting changes in the postoperative glomerular filtration rate (GFR) after unilateral nephrectomy in living kidney donors and patients with renal disease. We studied 141 subjects who underwent living donor nephrectomy for renal transplantation (n=75) or unilateral nephrectomy for renal diseases (n=66). The GFR of the individual kidney was determined by Tc-99m DTPA scintigraphy before and after nephrectomy. By performing multiple linear regression analysis, we evaluated the factors that are thought to affect changes in GFR, such as age, sex, body mass index (BMI), preoperative GFR, preoperative creatinine level, operated side, presence of diabetes mellitus (DM), presence of hypertension (HTN), and duration of follow-up. In both the donor nephrectomy and the disease nephrectomy groups, GFR increased significantly after nephrectomy (46.9{+-}8.4 to 58.1{+-}12.5 vs. 43.0{+-}9.6 to 48.6{+-}12.8 ml/min, p<0.05). In the donor nephrectomy group, age was significantly associated with change in GFR ({beta}=-0.3, P<0.005). In the disease nephrectomy group, HTN, preoperative creatinine level, and age were significantly associated with change in GFR ({beta}=-6.2, p<0.005; {beta}=-10.9, p<0.01; {beta}=-0.2, p<0.01, respectively). This compensatory change in GFR was not significantly related to sex, duration of follow-up, or operated side in either group. The compensatory change in the GFR of the remaining kidney declined with increasing age in both living kidney donors and patients with renal disease.

    Full Text Available CONTEXT AND OBJECTIVE: The adequacy of blood depends on blood donation rates and numbers of blood donors. To prepare adequate blood supplies, it is essential to investigate the barriers and factors that stop individuals from donating. This study aimed to identify the causes of lapsed donation at our center. DESIGN AND SETTING: Cross-sectional study of volunteer blood donors in Shiraz, Iran. METHODS: We selected 850 donors who had donated between January 1, 2005 and June 1, 2005, but had not donated again by June 2008. The participants were recruited by letter and telephone, and were interviewed using a specially designed questionnaire that contained items on demographic characteristics, donor motivations and reasons for not returning to donate. We used the chi-square test to identify associations between lapsed donor characteristics and reasons for declining to donate. RESULTS: The greatest motivation for donation was altruism. The most frequent reasons for lapsed donation were lack of time because of work and self-exclusion for medical reasons. Among first-time donors, the most frequent reasons were unsuitability for donation and lack of time. CONCLUSIONS: The reasons for not returning to donate are varied and may correlate with demographic characteristics. In this study, the main reason for not returning was lack of time. Changing donation hours so that donors can donate after work, providing mobile teams at workplaces, and shortening the duration of the donation process may help increase repeat donation rates.

  16. Current status of transplantation and organ donation in the Balkans--could it be improved through the South-eastern Europe Health Network (SEEHN) initiative? (United States)

    Organ donation and transplantation activity in the majority of Balkan countries (Albania, Bosnia and Herzegovina, Croatia, Macedonia, Moldova, Montenegro, Serbia, Romania and Bulgaria) are lagging far behind international averages. Inadequate financial resources, unclear regional data and lack of government infrastructure are some of the issues which should be recognized to draw attention and lead to problem-solving decisions. The Regional Health Development Centre (RHDC) Croatia, a technical body of the South-eastern Europe Health Network (SEEHN), was created in 2011 after Croatia's great success in the field over the last 10 years. The aim of the RHDC is to network the region and provide individualized country support to increase donation and transplantation activity in collaboration with professional societies (European Society of Organ Transplantation, European Transplant Coordinators Organization, The Transplantation Society and International Society of Organ Donation and Procurement). Such an improvement would in turn likely prevent transplant tourism. The regional data from 2010 show large discrepancies in donation and transplantation activities within geographically neighbouring countries. Thus, proposed actions to improve regional donation and transplantation rates include advancing living and deceased donation through regular public education, creating current and accurate waiting lists and increasing the number of educated transplant nephrologists and hospital coordinators. In addition to the effort from the professionals, government support with allocated funds per deceased donation, updated legislation and an established national coordinating body is ultimately recognized as essential for the successful donation and transplantation programmes. By continuous RHDC communication and support asked from the health authorities and motivated professionals from the SEEHN initiative, an increased number of deceased as well as living donor kidney

  17. Ethical aspects of organ donation activities. (United States)

    Stephan, Antoine; Barbari, Antoine; Younan, Farida


    Renal transplant remains the treatment of choice for patients with end-stage renal disease. Human organs can be harvested from 2 main sources: living and deceased donors. Preference should be given to deceased-donor transplants since they represent the only source of organs for several nonrenal solid-organ transplants and the only modality where there is no risk to the donor. Unfortunately, even the most well-developed deceased-donor program (eg, the Spanish program) can barely cover 50% of its waiting list because the demand for deceased-donor organs far exceeds supply. The success of transplant surgery has created a waiting list dilemma. Despite all efforts, deceased-donor donation cannot meet current needs and therefore, living donation demands serious consideration. This is supported by the fact that the risk to live donors is minimal, graft survival is significantly better than that of deceased-donor kidneys regardless of HLA matching, and professional ethical philosophers have fewer difficulties with voluntary living donations than with the removal of an organ from a cadaver. This is especially true in our region. Living-related donation has always been acceptable ethically. It is, however, limited by the number of willing and qualified donors, the high incidence of familial renal diseases, and donor coercion (especially in our area). Living-unrelated donation increases the availability of donors, decreases the chances of coercion, and eliminates the problem of consanguinity. It raises, however, the ethical issues of commercialism, transplant tourism, and organ trafficking. The arguments for and against living-unrelated donation are innumerable. They have been the subject of several international forums and have raised endless discussions. We have set long ago a series of rules and regulations that are in close agreement with the recent Amsterdam and Kuwait resolutions. We have been continually modifying them over the last 15 years to try to implement our

  18. [Need and demand of kidneys for transplantation in Venezuela]. (United States)

    Milanés, C L; Bellorín-Font, E; Weisinger, J; Pernalete, N; Urbina, D; Paz-Martínez, V


    The number of cadaveric kidneys available for transplantation has become insufficient around the world. Despite concerted efforts, we have been unsuccessful in greatly improve the supply of organ donors, and consequently the number of end stage renal failure patients awaiting for kidney transplantation continues to increase. The primary objective of this paper is to quantify the need and supply of kidneys for transplant in Venezuela. An overview of the current level of kidney transplant activity in Venezuela is presented, observing that the activity with cadaveric donors had been predominant since 1983, although not to an optimal level. The annual activity in kidney transplant between 1989-1991 remained stable in 6 transplants/million people, but went sharply down to 4.6 in 1992. An estimate of the current need is around 10 donors/million people. This is in contrast with an effective donation rate of only 2.01 and 1.92 donors/million achieved in 1990 and 1991 respectively. The most frequent cause for no donation was the lack of familiar consent. Based on an analysis of the factors involved in the shortage of donor supply in Venezuela, we present some recommendations to increase the availability of cadaveric organ donors in the country. These measures include an improvement of education and legal regulation in the field of organ donation and transplantation, and following the Spanish model, the creation of a program of hospital transplant coordinators that can detect and evaluate potential organ donors as well as coordinate the logistical aspects of transplantation.

  19. Self-rated appetite as a predictor of mortality in patients with stage 5 chronic kidney disease. (United States)

    To investigate the level of anorexia and its correlation with mortality in chronic kidney disease stage 5 patients not yet on dialysis (CKD5-ND) and in those with stage 5 chronic kidney disease undergoing dialysis (CKD5-D). In an observational study, self-rated appetite (as part of a subjective global assessment of nutritional status), along with anthropometrics and biochemical markers of nutritional status, was analyzed in relation to survival. In a subgroup of patients, appetite change after start of dialysis was studied prospectively. Two hundred eighty CKD5-ND (40% female; age 54 ± 12 years; glomerular filtration rate 7 ± 2 mL/minute) and 243 CKD5-D patients (116 hemodialysis and 127 peritoneal dialysis [PD]; 44% female; age 54 ± 12 years; dialysis vintage time 12 ± 2 months) who had been on dialysis for about 1 year were studied. CKD5-ND patients with poor appetite (50%) had a higher prevalence of cardiovascular disease, lower body weight and serum creatinine level, and higher C-reactive protein. CKD5-D patients with poor appetite (33%) had impaired subjective global assessment of nutritional status and lower body weight, fat body mass, handgrip strength, hemoglobin, and serum albumin level. In a Kaplan-Meier analysis, appetite was not associated with survival difference, whereas in the Cox proportional hazards model with competing risk analysis, poor appetite increased mortality risk in PD patients but not in hemodialysis and CKD5-ND patients. In CKD5-ND patients, self-rated appetite was not an independent predictor of 48-months survival, whereas there was a significant increase in mortality risk in PD patients with poor appetite.

  20. First-time whole blood donation: A critical step for donor safety and retention on first three donations. (United States)

    Gillet, P; Rapaille, A; Benoît, A; Ceinos, M; Bertrand, O; de Bouyalsky, I; Govaerts, B; Lambermont, M


    Whole blood donation is generally safe although vasovagal reactions can occur (approximately 1%). Risk factors are well known and prevention measures are shown as efficient. This study evaluates the impact of the donor's retention in relation to the occurrence of vasovagal reaction for the first three blood donations. Our study of data collected over three years evaluated the impact of classical risk factors and provided a model including the best combination of covariates predicting VVR. The impact of a reaction at first donation on return rate and complication until the third donation was evaluated. Our data (523,471 donations) confirmed the classical risk factors (gender, age, donor status and relative blood volume). After stepwise variable selection, donor status, relative blood volume and their interaction were the only remaining covariates in the model. Of 33,279 first-time donors monitored over a period of at least 15 months, the first three donations were followed. Data emphasised the impact of complication at first donation. The return rate for a second donation was reduced and the risk of vasovagal reaction was increased at least until the third donation. First-time donation is a crucial step in the donors' career. Donors who experienced a reaction at their first donation have a lower return rate for a second donation and a higher risk of vasovagal reaction at least until the third donation. Prevention measures have to be processed to improve donor retention and provide blood banks with adequate blood supply. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

  2. Financial incentives to increase Canadian organ donation: quick fix or fallacy? (United States)

    Gill, John S; Klarenbach, Scott; Barnieh, Lianne; Caulfield, Timothy; Knoll, Greg; Levin, Adeera; Cole, Edward H


    Unlike the United States, the potential to increase organ donation in Canada may be sufficient to meet the need for transplantation. However, there has been no national coordinated effort to increase organ donation. Strategies that do not involve payment for organs, such as investment in health care resources to support deceased donor organ donation and introduction of a remuneration framework for the work of deceased organ donation, should be prioritized for implementation. Financial incentives that may be permitted under existing legislation and that pose little risk to existing donation sources should be advanced, including the following: payment of funeral expenses for potential donors who register their decision on organ donation during life (irrespective of the decision to donate or actual organ donation) and removal of disincentives for directed and paired exchange living donation, such as payment of wages, payment for pain and suffering related to the donor surgery, and payment of directed living kidney donors for participation in Canada's paired exchange program. In contrast, it would be premature to contemplate a regulated system of organ sales that would require a paradigm shift in the current approach to organ donation and legislative change to implement.

    Full Text Available The link between serotonin (5-HT and one of the most important elements of prosocial behavior, charity, has remained largely uninvestigated. In the present study, we tested whether charitable donating can be promoted by administering the food supplement L-Tryptophan (TRP, the biochemical precursor of 5-HT. Participants were compared with respect to the amount of money they donated when given the opportunity to make a charitable donation. As expected, compared to a neutral placebo, TRP appears to increase the participants’ willingness to donate money to a charity. This result supports the idea that the food we eat may act as a cognitive enhancer modulating the way we think and perceive the world and others.

  5. Organ donations after death

    Directory of Open Access Journals (Sweden)

    Bernarda Logar


    Full Text Available The paper discusses public opinion on post-mortem organ donation, especially the difference between high support of public opinion to transplant activity, its general readiness to donate organs and the low number of signed organ donor cards. Through different approaches the article tries to point out possible factors relevant to the decision to donate organs. Early studies showed demographic variables and information as significant factors when deciding to donate organs after death. As there was not enough evidence that long-term effect through these factors is significant, the need for new investigation has grown. Social cognition theories helped understanding the difference mentioned above. It seems that the use of this approach might contribute to the understanding the problem and to delimit most useful factors when working with public.

    Shah, Malay B; Vilchez, Valery; Goble, Adam; Daily, Michael F; Berger, Jonathan C; Gedaly, Roberto; DuBay, Derek A


    Despite numerous initiatives to increase solid organs for transplant, the gap between donors and recipients widens. There is little in the literature identifying socioeconomic predictors for donation. We evaluate the correlation between socioeconomic factors and familial authorization for donation. A retrospective analysis of adult potential donor referrals between 2007 and 2012 to our organ procurement organization (OPO) was performed. Potential donor information was obtained from the OPO database, death certificates, and the US Census Report. Data on demographics, education, residence, income, registry status, cause and manner of death, as well as OPO assessments and approach for donation were collected. End point was familial authorization for donation. A total of 1059 potential donors were included, with an overall authorization rate of 47%. The majority was not on the donor registry (73%). Younger donors (18-39 y: odds ratio [OR] = 4.9, P donation first mentioned by the local health care provider (OR = 1.8, P = 0.01) were also independently associated with higher authorization rates. Donor registration correlated most strongly with the highest authorization rates. These results indicate that public educational efforts in populations with unfavorable socioeconomic considerations may be beneficial in improving donor registration. Collaborations with local providers as well as OPO in-hospital assessments and approach techniques can help with improving authorization rates. Copyright © 2017 Elsevier Inc. All rights reserved.

  8. Computed Tomography Volumetry in Preoperative Living Kidney Donor Assessment for Prediction of Split Renal Function. (United States)

    Wahba, Roger; Franke, Mareike; Hellmich, Martin; Kleinert, Robert; Cingöz, Tülay; Schmidt, Matthias C; Stippel, Dirk L; Bangard, Christopher


    Transplant centers commonly evaluate split renal function (SRF) with Tc-99m-mercapto-acetyltriglycin (MAG3) scintigraphy in living kidney donation. Alternatively, the kidney volume can be measured based on predonation CT scans. The aim of this study was to identify the most accurate CT volumetry technique for SRF and the prediction of postdonation kidney function (PDKF). Three CT volumetry techniques (modified ellipsoid volume [MELV], smart region of interest [ROI] volume, renal cortex volume [RCV]) were performed in 101 living kidney donors. Preoperation CT volumetric SRF was determined and compared with MAG3-SRF, postoperation donor kidney function, and graft function. The correlation between donors predonation total kidney volume and predonation kidney function was the highest for RCV (0.58 with creatine clearance, 0.54 with estimated glomerular filtration rate-Cockcroft-Gault). The predonation volume of the preserved kidney was (ROI, MELV, RCV) 148.0 ± 29.1 cm, 151.2 ± 35.4 and 93.9 ± 25.2 (P volumetry SRF and MAG3-SRF (bias, 95% limits of agreement: ROI vs MAG3 0.4%, -7.7% to 8.6%; MELV vs MAG3 0.4%, -8.9% to 9.7%; RCV vs MAG3 0.8%, -9.1% to 10.7%). The correlation between predonation CT volumetric SRF of the preserved kidney and PDKF at day 3 was r = 0.85 to 0.88, between MAG3-SRF and PDKF (r = 0.84). The difference of predonation SRF between preserved and donated kidney was the lowest for ROI and RCV (median, 3% and 4%; 95th percentile, 9% and 13%). Overall renal cortex volumetry seems to be the most accurate technique for the evaluation of predonation SRF and allows a reliable prediction of donor's PDKF.

  9. Psychosocial barriers associated with organ donation in Mexico. (United States)

    Marván, Maria Luisa; Álvarez Del Río, Asunción; Jasso, Kristian; Santillán-Doherty, Patricio


    There is a severe shortage of organs for transplantation worldwide, and Mexico has one of the lowest organ donation rates. In this study, we explored the psychosocial barriers that prevent posthumous organ donation by Mexicans. We asked 218 adults who were not willing to be donors to complete the sentence "I don't want to donate my organs after death because organ donation is…" The data were analyzed using the Natural Semantic Networks Technique. The most important answers given by the participants were related to mistrust. Older participants and those with limited education gave more answers that reflect misconceptions about organ donation. Many participants acknowledged its benefits, even though they did not want to be donors, especially the youngest and those with a higher education. Mistrust and poor education are problems that urgently need to be addressed in order to increase acceptance of organ donation and transplantation. © 2017 John Wiley & Sons A/S.

    Federica Fiacco, MD


    Full Text Available Background. Renal dysfunction in end-stage liver disease (ESLD results from systemic conditions that affect both liver and kidney with activation of vasoconstrictor systems. In this setting, estimated glomerular filtration rate (eGFR may undergo variations often outside Kidney Disease Improving Global Outcomes criteria for acute kidney injury (AKI diagnosis, whose meaning is not clear. The aim of this study was to evaluate eGFR variations in ESLD outpatients listed for liver transplant (liver Tx and the association with post-Tx outcome. Methods. Fifty-one patients with ESLD were retrospectively evaluated from listing to transplant (L-Tx time, intraoperatively (Tx time, and up to 5 years post-Tx time. Variations between the highest and the lowest eGFR occurring in more than 48 hours, not satisfying Kidney Disease Improving Global Outcomes guideline, were considered as fluctuations (eGFR-F. Fluctuations of eGFR greater than 50% were defined as eGFR drops (DeGFR. Early graft dysfunction, AKI within 7 days, chronic kidney disease, and short- and long-term patient survivals were considered as outcomes. Results. All patients presented eGFR-F, whereas DeGFR were observed in 18 (35.3% of 51 (DeGFR+ group. These patients presented higher levels of Model for End-stage Liver Disease score, pre-Tx bilirubin and significantly greater incidence of post-Tx AKI stages 2 to 3 compared with patients without drops (DeGFR−. DeGFR was the only independent predictive factor of the occurrence of post-Tx AKI. The occurrence of AKI post-Tx was associated with the development of chronic kidney disease at 3 months and 5 years post-Tx. Conclusions. Drops of eGFR are more frequently observed in patients with a worse degree of ESLD and are associated with a worse post-Tx kidney outcome.

  14. [HTLV and "donating" milk]. (United States)

    Rigourd, V; Meyer, V; Kieffer, F; Aubry, S; Magny, J-F


    In France, the screening for human T-cell leukemia/ lymphoma virus type 1 and 2 (HTLV-1 and HTLV-2) during the donation of human milk has been carried out from 1992 with the application of the circular DGS 24 November 1992. The screening for antibodies against these viruses is regulated and done systematically during every donation of milk. Breast feeding being the main mode of transmission of the HTLV-1, the last ministerial decree of 25 August 2010 has made the screening test compulsory for the anonymous donation and for the personalized donation (of a mother for her own child) from all women including those affected by the infection. The milk delivered by milk banks is pasteurized (62.5 °C for 30 minutes) before freezing at -18 °C, which inactivates the pathogens. This double means of prevention of the transmission of the HTLV-1 paradoxically seems disproportionate in the absence of any precautionary measure in the case of direct breast-feeding and the use of mother's raw milk. Indeed, in most neonatal intensive care units in maternity hospitals, unpasteurized milk is administered to the neonates without any systematic preliminary testing of the serological HTLV-1 status of the mother. An increased sensitization of the community of the obstetricians, midwives and neonatologists by the Association of the Milk Banks of France (ADLF) and the Société de pathologie exotique could address the issue of screening for HTLV-1 in "donated" milk and breast-feeding.

    Full Text Available AIM To study the changes in phosphate metabolism in kidney donors, to study the correlation of albuminuria, fractional excretion of phosphorus [FE Pi] and estimated glomerular filtration rate [eGFR] with fibroblast growth factor 23 [FGF 23] in kidney donors, to study the early tubule interstitial injury in the remnant kidney of donors by measuring urine transforming growth factor beta [TGF beta] levels. MATERIALS AND METHODS A cross-sectional study in which kidney donors with 1 year or more after donation were included. 69 kidney donors with a mean duration of 5.86 years after kidney donation were studied. Serum phosphate level, fractional excretion of phosphorus [FE Pi] and serum levels of parathyroid hormone were measured. Plasma levels of FGF 23 were measured by a second generation enzyme linked immune sorbent assay [ELISA]. Renal function was assessed by estimated glomerular filtration rate [eGFR] and degree of albuminuria. Urine levels of transforming growth factor beta [TGF beta] were measured by ELISA. A hypothesis that in kidney donors with reduced nephron number, the single nephron excretion of phosphorus will be increased to maintain normal phosphorus homeostasis and that this increase in single nephron phosphorus excretion may be mediated by FGF 23 was proposed. Testing of this hypothesis was done by studying the correlation between parameters of phosphorus metabolism, FGF 23 and the renal function of the donors. RESULTS The mean eGFR was 70.36 mL/min/1.73 m2 . 52.2% of donors had moderate increase in albuminuria [microalbuminuria], Serum phosphorus, fractional excretion of phosphorus and serum PTH levels were in the normal range. FGF 23 levels were in the normal reference range and showed no correlation with FE pi, eGFR or albuminuria, Urine TGF-beta levels were undetectable in all the donors. DISCUSSION Normal phosphorus homeostasis is maintained in kidney donors. There was no correlation between FE pi and FGF 23 levels. Kidney

    Luo, A J; Xie, W Z; Luo, J J; Ouyang, W


    Our aim was to (1) survey public' perception and attitudes toward organ donation and (2) analyze the relationship between knowledge, attitudes, and willingness to donate. We developed a questionnaire, and conducted the survey with stratified random sampling. Overall, 600 residents, aged ≥18 who resided in Hunan, and 600 undergraduates from 3 universities in Hunan were surveyed randomly. For this study, 1085 valid questionnaires were completed, with a response rate of 90.4%. Of the 1085 participants, 581 (53.5%) were students, 504 (46.5%) were residents, and 519 (47.8%) were male and 566 (52.2%) female. The mean accuracy rate was 71.96%, and the students' mean accuracy rate was slightly higher than that of the resident population (73.06% vs 70.68%, respectively). The results showed that 82.2% of public support organ donation, and 53.5% were willing to donate their organs after death. Students scored higher than the residents (88% vs 75.6% and 55.6% vs 51.2%). Nearly 1.8% felt that organ donation was against their religion, 14.9% thought it was important to ensure the integrity of the body, 71.7% agreed that organ donation allowed a positive outcome after a person's death, and 61.5% agreed that organ donation represented a continuation of life, to help families cope with grief. Age and gender were related to attitudes. Public knowledge of organ donation and their attitudes were correlated positively (r = 0.666). Public knowledge of organ donation is poor, biased, and incomplete, and based on television, movies, and communication networks. Positive attitudes toward donation displayed in the surveys were not matched by actual organ donation. Copyright © 2016 Elsevier Inc. All rights reserved.

  17. From fresh heterologous oocyte donation to autologous oocyte banking. (United States)

    Stoop, D


    Today, oocyte donation has become well established, giving rise to thousands of children born worldwide annually. The introduction of oocyte cryopreservation through vitrification allows the introduction of egg banking, improving the efficiency and comfort of oocyte donation. Moreover, the vitrification technique can now enable autologous donation of oocytes to prevent future infertility. We evaluated fresh heterologous oocyte donation in terms of obstetrical and perinatal outcome as well as of the reproductive outcome of past donors. We then evaluated the efficiency of a closed vitrification device and its clinical applications within ART. Thirdly, we evaluated the opinion of women with regard to preventive egg freezing and the efficiency of a human oocyte in relation to age. Oocyte donation is associated with an increased risk of first trimester bleeding and pregnancy induced hypertension. Donating oocytes does not seem to increase the likelihood for a later need of fertility treatment. The chance of an oocyte to result in live birth (utilization rate) in women women would consider safeguarding their reproductive potential through egg freezing or are at least open to the idea. The introduction of efficient oocyte cryopreservation has revolutionized oocyte donation through the establishment of eggbank donation. The technique also enables women to perform autologous donation after preventive oocyte storage in order to circumvent their biological clock.

  18. Young for young! Mandatory age-matched exchange of paediatric kidneys. (United States)

    Pape, Lars; Ehrich, Jochen H H; Offner, Gisela


    Some allocation systems include a mandatory donation of paediatric kidneys to children, others do not. Both approaches have medical and organisational advantages and disadvantages for adults and children. This article discusses why "young for young" is the best allocation system for children. Primary age-matched kidney allocation to children is one important factor leading to: (1) higher long-term glomerular filtration rates (GFRs) and graft survival and, thereby, to lesser need for dialysis; (2) better psychosocial rehabilitation, growth and development of children and, last but not least, (3) likely increase of the donor pool. As a consequence, health care costs will be reduced for children with end-stage renal failure. The chance of adults receiving an adequate kidney would be only minimally reduced by this policy. Therefore, we recommend an age-matched allocation programme giving children with end- stage kidney diseases a better prognosis.

  19. A Confirmatory Analysis of the Organ Donation Readiness Index: Measuring the Potential for Organ Donations among African Americans (United States)

    Rice, Christopher; Tamburlin, Judith


    The need for transplant exceeds the number of available organs. Antigen compatible organs are particularly scarce for African Americans because of their proportionately lower rate of donations. This study presents a measure of organ donation readiness. Examination of the factor structure and a test of weak invariance were conducted on…

    Chronic kidney disease (CKD) has often been defined based on glomerular filtration rate (GFR) alone. The Kidney Disease: Improving Global Outcomes guideline highlights albuminuria in the CKD definition. Thus, we investigated the association between obesity and CKD, as defined by both GFR and albuminuria, in Korean adults. We used Korea National Health and Nutrition Examination Survey 2011-2014 data (N = 19,331, ≥19 years old) representing the national Korean population. CKD was classified by (1) estimated GFR (eGFR) obesity and each CKD category were evaluated using multivariate logistic regression analysis. The prevalence rates of CKD GFR , CKD ACR , and CKD Risk were 2.2%, 6.7%, and 8.1%, respectively. Compared with the normal body mass index (BMI; 18.5-22.9 kg/m 2 ) group, men with BMI ≥ 25 kg/m 2 had 1.88 times greater risk of CKD GFR in the adjusted model [95% confidence interval (CI), 1.26-2.80; P = 0.002]; BMI was not significantly associated with CKD GFR in women. In contrast, both men and women with BMI ≥ 25 kg/m 2 had 1.58 and 1.40 times higher risk of CKD ACR (95% CI, 1.21-2.07 and 1.08-1.81, respectively, both P Obese men and women had 1.65 and 1.38 times higher risk of CKD Risk (95% CI, 1.29-2.12 and 1.09-1.75, respectively, both P Obesity was significantly associated with an increased ACR-based CKD risk. Longitudinal studies are needed to investigate the role of overweight and obesity in the development and progression of CKD.

  1. Increasing the supply of kidneys for transplantation by making living donors the preferred source of donor kidneys. (United States)

    Testa, Giuliano; Siegler, Mark


    At the present time, increasing the use of living donors offers the best solution to the organ shortage problem. The clinical questions raised when the first living donor kidney transplant was performed, involving donor risk, informed consent, donor protection, and organ quality, have been largely answered. We strongly encourage a wider utilization of living donation and recommend that living donation, rather than deceased donation, become the first choice for kidney transplantation. We believe that it is ethically sound to have living kidney donation as the primary source for organs when the mortality and morbidity risks to the donor are known and kept extremely low, when the donor is properly informed and protected from coercion, and when accepted national and local guidelines for living donation are followed.

  2. Use of spiral CT and the contrast medium iohexol to determine in one session aortorenal morphology and the relative glomerular filtration rate of each kidney

    International Nuclear Information System (INIS)

    Frennby, B.; Almen, T.


    The aim of this study was to determine the relative glomerular filtration rate (GFR), i.e. the GFR of each kidney in percent of total GFR, by spiral CT. In 41 patients, who were part of a follow-up program after endoluminal stent grafting of aortic aneurysm, spiral CT with the contrast medium iohexol was used to evaluate the morphology of the aorta and kidneys. The opportunity was taken to utilize the already injected iohexol to determine the relative GFR with an extra CT sequence. In each patient two determinations were made, 6 or 12 months apart. The amount of a GFR marker accumulating in Bowman's space, tubuli, and renal pelvis within 2-3 min after i.v. injection, before any marker had left the kidney via the ureter, was defined as proportional to the GFR of that kidney. The renal accumulation of iohexol was obtained by spiral CT using 10-mm collimation and a table speed of 10 mm/s (pitch ratio 1:1) from the upper to the lower poles. The correlation coefficient between the relative GFR of each kidney determined at the first and second examination was excellent (r=0.99) with a median (range) difference of 1% (0-6%) of total GFR. The radiation dose calculated as the mean absorbed dose to the kidneys was 50 mGy and the effective dose 5 mSv. The morphology of aorta and kidneys and the relative GFR of each kidney can be determined in one session with spiral CT using iohexol as both angiographic contrast medium and as a GFR marker. It is also possible to take some plasma samples in the same session to determine iohexol concentration to calculate the body clearance of iohexol (or take plasma and urine samples to calculate the renal clearance of iohexol).

    Oral phosphate binders are the main stay of treatment of hyperphosphatemia. Adherence rates to ferric citrate, a recently approved phosphate binder, are unknown. We conducted a post-hoc analysis to evaluate whether adherence rates were different for ferric citrate vs. active control in 412 subjects with end stage kidney disease (ESKD) who were randomized to ferric citrate vs. active control (sevelamer carbonate and/or calcium acetate). Adherence was defined as percent of actual number of pills taken to total number of pills prescribed. There were no significant differences in baseline characteristics including gender, race/ethnicity, and age between the ferric citrate and active control groups. Baseline phosphorus, calcium, and parathyroid hormone levels were similar. Mean (SD) adherence was 81.4% (17.4) and 81.7% (15.9) in the ferric citrate and active control groups, respectively (P = 0.88). Adherence remained similar between both groups after adjusting for gender, race/ethnicity, age, cardiovascular disease (CVD), and diabetic nephropathy (mean [95% CI]: 81.4% [78.2, 84.6] and 81.5% [77.7, 85.2] for ferric citrate and active control, respectively). Gender, race/ethnicity, age, and diagnosis of diabetic nephropathy did not influence adherence to the prescribed phosphate binder. Subjects with CVD had lower adherence rates to phosphate binder; this was significant only in the active control group. Adherence rates to the phosphate binder, ferric citrate, were similar to adherence rates to active control. Similar adherence rates to ferric citrate are notable since tolerance to active control was an entry criteria and the study was open label. Gender, race/ethnicity, nor age influenced adherence. © 2016 International Society for Hemodialysis.

  7. Estimated Glomerular Filtration Rate Correlates Poorly with Four-Hour Creatinine Clearance in Critically Ill Patients with Acute Kidney Injury

    Directory of Open Access Journals (Sweden)

    Christopher J. Kirwan


    Full Text Available Introduction. RIFLE and AKIN provide a standardised classification of acute kidney injury (AKI, but their categorical rather than continuous nature restricts their use to a research tool. A more accurate real-time description of renal function in AKI is needed, and some published data suggest that equations based on serum creatinine that estimate glomerular filtration rate (eGFR can provide this. In addition, incorporating serum cystatin C concentration into estimates of GFR may improve their accuracy, but no eGFR equations are validated in critically ill patients with AKI. Aim. This study tests whether creatinine or cystatin-C-based eGFR equations, used in patients with CKD, offer an accurate representation of 4-hour creatinine clearance (4CrCl in critically ill patients with AKI. Methods. Fifty-one critically ill patients with AKI were recruited. Thirty-seven met inclusion criteria, and the performance of eGFR equations was compared to 4CrCl. Results. eGFR equations were better than creatinine alone at predicting 4CrCl. Adding cystatin C to estimates did not improve the bias or add accuracy. The MDRD 7 eGFR had the best combination of correlation, bias, percentage error and accuracy. None were near acceptable standards quoted in patients with chronic kidney disease (CKD. Conclusions. eGFR equations are not sufficiently accurate for use in critically ill patients with AKI. Incorporating serum cystatin C does not improve estimates. eGFR should not be used to describe renal function in patients with AKI. Standards of accuracy for validating eGFR need to be set.

  8. Safety and frequency of whole blood donations from elderly donors. (United States)

    Müller-Steinhardt, M; Müller-Kuller, T; Weiss, C; Menzel, D; Wiesneth, M; Seifried, E; Klüter, H


    Within the coming decades, a steadily growing demand for blood products will face a shrinking blood donor population in many countries. After increasing the donor age of repeat donors for whole blood donation (WB) from 68 to 70 years in 2009 in our Blood Service, we investigated whether this is sufficient as a safe and effective strategy to sustain future blood supply. Between 1 March 2009 and 28 February 2011, WB donations from donors aged between 69 and 70 and their proportion of total donations in 2010 were determined. We analysed adverse reaction rates in donors with respect to sex and age and calculated mean annual donation frequencies. Of all invited donors, 32·5% responded and contributed 0·98% (men) and 0·56% (women) to all WB units collected in 2010. The overall and systemic adverse reaction rate per 1·000 WB donations declined by age [men: 1·10 (95%CI: 0·84-1·35) vs. 0 (0-0·8), P donation frequencies were strongly correlated with increasing age (men: r = 0·953, P donate blood. Thus, we consider donations from repeat donors aged 69-70 safe and suggest it a powerful short- to midterm strategy to, at least partially, overcome the challenges of the demographic change. © 2011 The Author(s).

  9. Subsequent donation requests among 2472 unrelated hematopoietic progenitor cell donors are associated with bone marrow harvest (United States)

    Lown, Robert N.; Tulpule, Sameer; Russell, Nigel H.; Craddock, Charles F.; Roest, Rochelle; Madrigal, J. Alejandro; Shaw, Bronwen E.


    Approximately 1 in 20 unrelated donors are asked to make a second donation of hematopoietic progenitor cells, the majority for the same patient. Anthony Nolan undertook a study of subsequent hematopoietic progenitor cell donations made by its donors from 2005 to 2011, with the aims of predicting those donors more likely to be called for a second donation, assessing rates of serious adverse reactions and examining harvest yields. This was not a study of factors predictive of second allografts. During the study period 2591 donations were made, of which 120 (4.6%) were subsequent donations. The median time between donations was 179 days (range, 21–4016). Indications for a second allogeneic transplant included primary graft failure (11.7%), secondary graft failure (53.2%), relapse (30.6%) and others (1.8%). On multivariate analysis, bone marrow harvest at first donation was associated with subsequent donation requests (odds ratio 2.00, P=0.001). The rate of serious adverse reactions in donors making a subsequent donation appeared greater than the rate in those making a first donation (relative risk=3.29, P=0.005). Harvest yields per kilogram recipient body weight were equivalent between donations, although females appeared to have a lower yield at the subsequent donation. Knowledge of these factors will help unrelated donor registries to counsel their donors. PMID:23812935

  10. In defense of a regulated system of compensation for living donation. (United States)

    Matas, Arthur J; Hippen, Benjamin; Satel, Sally


    The organ shortage is the major problem in kidney transplantation today. Despite aggressive organ procurement efforts, the supply of donated kidneys, living and deceased, has not matched the growing demand; as a consequence, more and more qualified candidates are suffering on dialysis and then dying before being transplanted. Herein, we provide justification for a regulated system of compensation for donation. The main argument in favor of compensation is simple-financial incentives will increase donation, so fewer transplant candidates will suffer and die while waiting. In addition, development of a regulated system of compensation is the most effective means of crippling the core economic support for transplant tourism. Because dialysis is so much more expensive than a transplant, compensated donation could be cost-neutral to the healthcare system. Importantly, opinion polls suggest that the public would support compensation. As uncompensated kidney donation is widely accepted, persuasive arguments against compensation must explain why such a system would be morally distinguishable from uncompensated donation. We suggest that the potential advantages of a regulated system of compensation for donation far outweigh any potential disadvantages. It is time to advocate for a change in the law so that trials can be done.

  11. Does organ donation legislation affect individuals' willingness to donate their own or their relative's organs? Evidence from European Union survey data. (United States)

    Mossialos, Elias; Costa-Font, Joan; Rudisill, Caroline


    Maintaining adequately high organ donation rates proves essential to offering patients all appropriate and available treatment options. However, the act of donation is in itself an individual decision that requires a depth of understanding that interacts with the social setting and the institutional framework into which an individual is embedded. This study contributes to understanding factors driving organ donation rates by examining how country regulation, individuals' awareness of regulatory setting, social interactions and socio-demographic determinants influence individuals' willingness to donate their own organs or those of a relative. We draw representative data from the Eurobarometer survey 58.2 undertaken in 2002 with respondents throughout the European Union to capture heterogeneity in institutional setting. We use logistic regression techniques to estimate the determinants of willingness to donate one's own organs and those of a deceased relative. We employ interaction terms to examine the relationship between institutional setting and respondent's awareness of organ donation legislation in their country. Our findings indicate that individuals are more likely to donate their organs than to consent to the donation of a relative's organs. Both decisions are affected by regulation (presumed consent), awareness of regulation and social interactions such as the ability to count on others in case of a serious problem (reciprocity). Furthermore, education (more educated), age (younger), expressing some sort of political affiliation determine willingness to donate one's own organs and consent to the donation of those of a relative. This study confirms and develops further previous research findings that presumed consent organ donation policy positively affects the willingness of individuals to donate their own organs and those of relative by highlighting the importance of awareness of this regulation and an individual's level of social interactions in making

  12. Risk for cancer in living kidney donors and recipients. (United States)

    Wang, Min; Zhang, Huai; Zhou, Dan; Qiao, Yong-Chao; Pan, Yan-Hong; Wang, Yan-Chao; Zhao, Hai-Lu


    Malignancy following renal transplantation remains inconsistent with the reported safety of kidney donation during the long-term follow-up. We conducted searches of the published literature which included healthy participants, recipients, living kidney donors (LKDs), and the availability of outcome data for malignancy. Eight from 938 potentially relevant studies were analyzed by means of fixed-effects model or random-effects model, as appropriately. In 48,950 participants, the follow-up range was 18 months to 20 years, and the mean age of the subjects was approximately 41 years. The incidence rate with 95% confidence interval (CI) for malignancy after kidney transplantation was 0.03 (0.01-0.05) in recipients and 0.03 (0.1-0.07) in LKDs, giving a pooled incidence rate of 0.03 (95% CI 0.02-0.04). LKDs contrasted nondonors by the overall odds ratio and 95% CI for total cancer of 2.80 (2.69-2.92). Kidney transplantation was associated with an increased risk of cancer during a long-term follow-up. Long-term risk for cancer in LKDs and kidney recipients should be monitored.

  13. How Research on Charitable Giving Can Inform Strategies to Promote Human Milk Donations to Milk Banks. (United States)

    Stevens, Jack; Keim, Sarah A


    Many hospitalized preterm infants do not exclusively receive mother's own milk, so milk from another mother may be sought. Previous research indicated that just 1% of US women who express breast milk actually donate it for another family. Therefore, strategies to boost donation rates should be identified. We draw upon the experimental literature on charitable giving of monetary donations to offer 6 strategies to promote breast milk donations to milk banks in North America. These strategies include (1) highlighting a potential identifiable recipient of donated breast milk as opposed to highlighting groups of potential recipients; (2) emphasizing similarities between the potential donor and potential beneficiaries; (3) emphasizing similarities between the potential donor and previous donors; (4) using negative arousal to promote donations; (5) emphasizing the self-interest of those asking for breast milk donations; and (6) highlighting the specific effect of breast milk donations. Potential limitations of these strategies are discussed. © The Author(s) 2015.

  14. Kidney paired exchange and desensitization: Strategies to transplant the difficult to match kidney patients with living donors. (United States)

    Pham, Thomas A; Lee, Jacqueline I; Melcher, Marc L


    With organs in short supply, only a limited number of kidney transplants can be performed a year. Live donor donation accounts for 1/3rd of all kidney transplants performed in the United States. Unfortunately, not every donor recipient pair is feasible because of Human leukocyte antigen (HLA) sensitization and ABO incompatibility. To overcome these barriers to transplant, strategies such as kidney paired donation (KPD) and desensitization have been developed. KPD is the exchange of donors between at least two incompatible donor-recipient pairs such that they are now compatible. Desensitization is the removal of circulating donor specific antibodies to prevent graft rejection. Regardless of the treatment strategy, highly sensitized patients whose calculated panel reactive antibody (cPRA) is ≥95% remain difficult to transplant with match rates as low as 15% in KPD pools. Desensitization has proved to be difficult in those with high antibody titers. A novel approach is the combination of both KPD and desensitization to facilitate compatible and successful transplantation. A highly sensitized patient can be paired with a better immunological match in the KPD pool and subsequently desensitized to a lesser degree. This article reviews the current progress in KPD and desensitization and their use as a combined therapy. Copyright © 2017 Elsevier Inc. All rights reserved.

  19. [Outcome of living kidney donors for transplantation]. (United States)

    Lanot, Antoine; Bouvier, Nicolas; Chatelet, Valérie; Lecouf, Angélique; Tillou, Xavier; Hurault de Ligny, Bruno


    Nowadays, several treatments exist to treat terminal chronic renal failure. Best results for the recipients are obtained with kidney transplantation concerning mortality and quality of life. Transplantation is also the cheaper option for society. Living kidney donation raises the issue of the becoming of the donor, an absolutely healthy subject who gets to a surgical procedure. The becoming of living kidney donors has been compared with the one of controls subjects in several studies. The evaluations focused on the complications of nephrectomy in the short and long-term: kidney failure, hypertension, proteinuria, possibility of pregnancy, quality of life, and mortality. The first results did not show any risk linked to kidney donation, compared to general population. However, since 2013, kidney donors were found at higher risk for kidney failure and even for mortality, compared with controls selected like donor candidates. The risk of kidney donation is nevertheless acceptable and minimal, on the condition of rigorous selection of candidates and regular follow-up.

  20. Donation return time at fixed and mobile donation sites (United States)

    Carey, Patricia M.; High, Patrick M.; Schlumpf, Karen S.; Johnson, Bryce R.; Mast, Alan E.; Rios, Jorge A.; Simon, Toby L.; Wilkinson, Susan L.


    BACKGROUND This study investigated the effect of blood donation environment, fixed or mobile with differing sponsor types, on donation return time. STUDY DESIGN AND METHODS Data from 2006 through 2009 at six US blood centers participating in the Retrovirus Epidemiology Donor Study-II (REDS-II) were used for analysis. Descriptive statistics stratified by whole blood (WB), plateletpheresis (PP), and double red blood cell (R2) donations were obtained for fixed and mobile locations, including median number of donations and median interdonation interval. A survival analysis estimated median return time at fixed and mobile sites, while controlling for censored return times, demographics, blood center, and mandatory recovery times. RESULTS Two-thirds (67.9%) of WB donations were made at mobile sites, 97.4% of PP donations were made at fixed sites, and R2 donations were equally distributed between fixed and mobile locations. For donations at fixed sites only or alternating between fixed and mobile sites, the highest median numbers of donations were nine and eight, respectively, and the shortest model-adjusted median return times (controlling for mandatory eligibility times of 56 and 112 days) were 36 and 30 days for WB and R2 donations, respectively. For PP donations, the shortest model-adjusted median return time was 23 days at a fixed location and the longest was 693 days at community locations. CONCLUSION WB, PP, and R2 donors with the shortest time between donations were associated with fixed locations and those alternating between fixed and mobile locations, even after controlling for differing mandatory recovery times for the different blood donation procedures.

    Full Text Available BackgroundIt is known that metabolic syndrome (MetS is associated with chronic kidney disease. We evaluated and compared the prevalence of reduced kidney function in MetS and its components by estimated glomerular filtration rate (eGFR using an equation based on creatinine (eGFRcr, cystatin C (eGFRcys, and combined creatinine-cystatin C (eGFRcr-cys in Korean adults.MethodsWe analyzed data from 3,649 adults who participated in a comprehensive health examination.ResultsMean values of eGFRcys were higher compared with mean values of eGFRcr (96.1±18.2 mL/min/1.73 m2 vs. 91.2±13.6 mL/min/1.73 m2 in total subjects. The prevalence of reduced kidney function increased with age (9.6% for eGFRcys vs. 5.8% for eGFRcr-cys vs. 4.9% for eGFRcr, in subjects aged ≥60 years, and significantly increased with MetS, abdominal obesity, hypertension, high triglyceride, low high density lipoprotein (HDL, and high insulin resistance. The prevalence of MetS, abdominal obesity, hypertension, high insulin resistance, low HDL, and hepatic steatosis was significantly increased in subjects with reduced kidney function. This increased prevalence and the odds ratio of reduced kidney function for prevalence of MetS was highest for eGFRcys, followed by those of eGFRcr-cys, and eGFRcr.ConclusionThe prevalence of reduced kidney function by eGFR was significantly increased in subjects with MetS and its related components. eGFRcys and eGFRcr-cys were superior to eGFRcr in detecting reduced kidney function.

  2. Attitudes to cadaveric organ donation in Irish preclinical medical students.

    LENUS (Irish Health Repository)

    Cahill, Kevin C


    There is a worldwide shortage of organs for transplantation. It has been shown that the attitude of healthcare professionals can improve the rates of organ donation, and that educational programs aimed at improving both attitudes and knowledge base of professionals can have positive outcomes. Although there has been research carried out on this topic, there has been none in Ireland. Anatomy dissection can be a stressor to medical students-we investigate the attitudes of Irish students to organ donation and how they change with exposure to anatomy dissection. A questionnaire was administered to first year students in the School of Medicine in University College Dublin, Ireland, three times over a nine-week period at the commencement of classes in an academic year. The attitudes of the students were positive throughout regarding organ donation by a stranger, a family member, or themselves. There was, however, a significant decrease in support for the donation of a family member\\'s organs in a minority of students. Irish students\\' attitudes to postmortem organ donation are positive and are not changed by exposure to the dissecting room. There is support for the donation of organs, and willingness among students to donate their own organs and support donation by family members.

    Holtzman, Susan; Adcock, Lesley; Dubay, Derek A; Therapondos, George; Kashfi, Arash; Greenwood, Sarah; Renner, Eberhard L; Grant, David R; Levy, Gary A; Abbey, Susan E


    The ability to inform prospective donors of the psychosocial risks of living liver donation is currently limited by the scant empirical literature. The present study was designed to examine donor perceptions of the impact of donation on financial, vocational, and interpersonal life domains and identify demographic and clinical factors related to longer recovery times and greater life interference. A total of 143 donors completed a retrospective questionnaire that included a standardized measure of life interference [Illness Intrusiveness Rating Scale (IIRS)] and additional questions regarding the perceived impact of donation. Donor IIRS scores suggested that donors experience a relatively low level of life interference due to donation [1.60 +/- 0.72, with a possible range of 1 ("not very much" interference) to 7 ("very much" interference)]. However, approximately 1 in 5 donors reported that donating was a significant financial burden. Logistic regression analysis revealed that donors with a psychiatric diagnosis at or prior to donation took longer to return to their self-reported predonation level of functioning (odds ratio = 3.78, P = 0.016). Medical complications were unrelated to self-reported recovery time. Multiple regression analysis revealed 4 independent predictors of greater life interference: less time since donation (b = 0.11, P financial burden of donation.

    While fluid overload (FO) and alterations in the autonomic nervous system (ANS) such as hypersympathetic activity, are known risk factors for cardiovascular morbidity and mortality in patients on chronic hemodialysis (HD), their relationship has not been thoroughly studied. In this observational study involving 69 patients on chronic HD, FO was assessed by whole body bioimpedance measurements before the midweek HD session and ANS activity reflected by Heart Rate Variability (HRV) was measured using 24-hour Holter electrocardiogram recordings starting before the same HD treatment. In total, 13 different HRV indices were analyzed, comprising a mixture of time domain, frequency domain and complexity parameters. A correlation analysis was performed between the HRV indices and hydration status indices. Successively, patients were retrospectively assigned to a high FO (H, FO > 2.5 L) or low FO (L, FO ≤ 2.5 L) group and these were further compared also after stratification by diabetes mellitus. Finally, a small number of patients without diabetes with significant and persistent FO were followed up for 3 months post-study to investigate how normalization of fluid status affects HRV. SDANN, VLF, LZC and HF% parameters significantly correlate with FO (correlation coefficients were respectively r = -0.40, r = -0.37, r = -0.28 and r = 0.26, p-value hydration status (correlation coefficients were respectively r = -0.31 and r = -0.33, p-value hydration status is accompanied by improved HRV.

    BACKGROUND: Whether or not the association between some antiretrovirals used in HIV infection and chronic kidney disease is cumulative is a controversial topic, especially in patients with initially normal renal function. In this study, we aimed to investigate the association between duration...... of exposure to antiretrovirals and the development of chronic kidney disease in people with initially normal renal function, as measured by estimated glomerular filtration rate (eGFR). METHODS: In this prospective international cohort study, HIV-positive adult participants (aged ≥16 years) from the D......:A:D study (based in Europe, the USA, and Australia) with first eGFR greater than 90 mL/min per 1·73 m(2) were followed from baseline (first eGFR measurement after Jan 1, 2004) until the occurrence of one of the following: chronic kidney disease; last eGFR measurement; Feb 1, 2014; or final visit plus 6...

  6. Assessing the kidney function parameters glomerular filtration rate and effective renal plasma flow with dynamic FDG-PET/MRI in healthy subjects. (United States)

    Geist, Barbara K; Baltzer, Pascal; Fueger, Barbara; Hamboeck, Martina; Nakuz, Thomas; Papp, Laszlo; Rasul, Sazan; Sundar, Lalith Kumar Shiyam; Hacker, Marcus; Staudenherz, Anton


    A method was developed to assess the kidney parameters glomerular filtration rate (GFR) and effective renal plasma flow (ERPF) from 2-deoxy-2-[ 18 F]fluoro-D-glucose (FDG) concentration behavior in kidneys, measured with positron emission tomography (PET) scans. Twenty-four healthy adult subjects prospectively underwent dynamic simultaneous PET/magnetic resonance imaging (MRI) examination. Time activity curves (TACs) were obtained from the dynamic PET series, with the guidance of MR information. Patlak analysis was performed to determine the GFR, and based on integrals, ERPF was calculated. Results were compared to intra-individually obtained reference values determined from venous blood samples. Total kidney GFR and ERPF as estimated by dynamic PET/MRI were highly correlated to their reference values (r = 0.88/p dynamic FDG PET/MRI scans in healthy kidneys. This has advantages for patients getting a routine scan, where additional examinations for kidney function estimation could be avoided. Further studies are required for transferring this PET/MRI method to PET/CT applications.

  7. Crowdfunding as 'Donations'

    DEFF Research Database (Denmark)

    Boudreau, Kevin J.; Jeppesen, Lars Bo; Reichstein, Toke

    For a wide class of crowdfunding approaches, we argue that the reward structure (for funders) is closer to that of charitable donations to public goods than it is to traditional entrepreneurial finance. Many features of the design of crowdfunding platforms can therefore be understood as attempts...... to deal with attendant “free-rider” problems in motivating contributions. Reviewing institutional features of today’s crowdfunding, we clarify that there are often limits in the extent to which tangible rewards can be used to motivate contributions. Drawing on analogies with charitable donations, we...... theorize that intangible sources of motivation — (i) direct psychological rewards, (ii) reciprocity and (iii) social interactions — can play a role in entrepreneurial crowdfunding. In our detailed empirical analysis of a representative project we find abundant evidence consistent with this characterization...

  9. Health Literacy of Living Kidney Donors and Kidney Transplant Recipients (United States)

    Dageforde, Leigh Anne; Petersen, Alec W.; Feurer, Irene D.; Cavanaugh, Kerri L.; Harms, Kelly A.; Ehrenfeld, Jesse M.; Moore, Derek E.


    Background Health literacy (HL) may be a mediator for known socioeconomic and racial disparities in living kidney donation. Methods We evaluated the associations of patient and demographic characteristics with HL in living kidney donors (LD), living donor kidney transplant recipients (LDR), and deceased donor recipients (DDR) in a single center retrospective review of patients undergoing kidney donation or transplantation from September 2010 to July 2012. HL and demographic data were collected. HL was assessed via the Short Literacy Survey (SLS) comprising three self-reported screening questions scored using the 5-point Likert scale [low (3-8), moderate (9-14), high (15)]. Chi-square and logistic regression were used to test factors associated with lower HL. Results The sample included 360 adults (105 LD, 103 LDR, 152 DDR; 46±14 years; 70% white; 56% male; 14±3 years of education). HL scores were skewed (49% high, 41% moderate, 10% low). The distribution of HL categories differed significantly among groups (p=0.019). After controlling for age, race, gender, education and a race-education interaction term, DDR were more likely to have moderate or low HL than LDR (OR 1.911; 95%CI 1.096, 3.332; p=0.022) Conclusions Overall, living donors had high HL. The distribution of low, moderate and high HL differed significantly between LD, DDR and LDR. DDR had a higher likelihood of having low HL than LDR. Screening kidney transplant candidates and donors for lower HL may identify barriers to living donation. Future interventions addressing HL may be important to increase living donation and reduce disparities. PMID:24573114

  10. Risk-Factor Profile of Living Kidney Donors: The Australia and New Zealand Dialysis and Transplant Living Kidney Donor Registry 2004-2012. (United States)

    Clayton, Philip A; Saunders, John R; McDonald, Stephen P; Allen, Richard D M; Pilmore, Helen; Saunder, Alan; Boudville, Neil; Chadban, Steven J


    Recent literature suggests that living kidney donation may be associated with an excess risk of end-stage kidney disease and death. Efforts to maximize access to transplantation may result in acceptance of donors who do not fit within current guidelines, potentially placing them at risk of adverse long-term outcomes. We studied the risk profile of Australian and New Zealand living kidney donors using data from the Australia and New Zealand Dialysis and Transplant Living Kidney Donor Registry over 2004 to 2012. We compared their predonation profile against national guidelines for donor acceptance. The analysis included 2,932 donors (mean age 48.8 ± 11.2 years, range 18-81), 58% female and 87% Caucasian. Forty (1%) had measured glomerular filtration rate less than 80 mL/min; 32 (1%) had proteinuria >300 mg/day; 589 (20%) were hypertensive; 495 (18%) obese; 9 (0.3%) were diabetic while a further 55 (2%) had impaired glucose tolerance; and 218 (7%) were current smokers. Overall 767 donors (26%) had at least one relative contraindication to donation and 268 (9%) had at least one absolute contraindication according to national guidelines. Divergence of current clinical practice from national guidelines has occurred. In the context of recent evidence demonstrating elevated long-term donor risk, rigorous follow-up and reporting of outcomes are now mandated to ensure safety and document any change in risk associated with such a divergence.

  11. Reliability of single kidney glomerular filtration rate measured by a 99mTc-DTPA gamma camera technique

    International Nuclear Information System (INIS)

    Rehling, M.; Moller, M.L.; Jensen, J.J.; Thamdrup, B.; Lund, J.O.; Trap-Jensen, J.


    The reliability of a previously published method for determination of single kidney glomerular filtration rate (SKGFR) by means of technetium-99m-diethylenetriaminepenta-acetate (99mTc-DTPA) gamma camera renography was evaluated. The day-to-day variation in the calculated SKGFR values was earlier found to be 8.8%. The technique was compared to the simultaneously measured renal clearance of inulin in 19 unilaterally nephrectomized patients with GFR varying from 11 to 76 ml/min. The regression line (y = 1.04 X -2.5) did not differ significantly from the line of identity. The standard error of estimate was 4.3 ml/min. In 17 patients the inter- and intraobserver variation of the calculated SKGFR values was 1.2 ml/min and 1.3 ml/min, respectively. In 21 of 25 healthy subjects studied (age range 27-29 years), total GFR calculated from the renograms was within an established age-dependent normal range of GFR

  12. Correlation between ultrafiltration rate and phase angle measured by BIA in chronic kidney disease patients on regular hemodialysis (United States)

    Nasution, B. R.; Lubis, A. R.


    Chronic Kidney Disease (CKD) patients with regular hemodialysis have high rates of morbidity and mortality that may be related to the hemodynamic effects of rapid UFR and low PhA value. In this study, we investigated whether high UFR is associated with a low value of PhA thus indirectly affect the risk of morbidity and mortality. UFR and Bioelectrical Impedance Analysis (BIA) examination on 92 subjects were recorded shortly after HD and analyzed by using Pearson correlation test. Multivariate analysis was also conducted to identify several factors that can affect the value of Phase angle. The number of HD regular CKD patients with PhA<4 based on the division of the UFR (cc/kg/h) <10, 10-13, ≥ 13, respectively were3, 10 and 6, whereas patients with ≥ 4 PhA <10, 10-13, ≥ 13respectively were 60, 11, and 2. The results showed a significant relationship between UFR with PhA. In CKD patients with regular HD, UFR has aninverse relationship with the value of PhA. After multivariate analysis, the UFR and the etiology of HD are still significantly affect the value of PhA. UFR optimal value in patients with CKD with regular HD is <10 cc/kg/h.

  13. The TALKS study to improve communication, logistical, and financial barriers to live donor kidney transplantation in African Americans: protocol of a randomized clinical trial. (United States)

    Live donor kidney transplantation (LDKT), an optimal therapy for many patients with end-stage kidney disease, is underutilized, particularly by African Americans. Potential recipient difficulties initiating and sustaining conversations about LDKT, identifying willing and medically eligible donors, and potential donors' logistical and financial hurdles have been cited as potential contributors to race disparities in LDKT. Few interventions specifically targeting these factors have been tested. We report the protocol of the Talking about Living Kidney Donation Support (TALKS) study, a study designed to evaluate the effectiveness of behavioral, educational and financial assistance interventions to improve access to LDKT among African Americans on the deceased donor kidney transplant recipient waiting list. We adapted a previously tested educational and social worker intervention shown to improve consideration and pursuit of LDKT among patients and their family members for its use among patients on the kidney transplant waiting list. We also developed a financial assistance intervention to help potential donors overcome logistical and financial challenges they might face during the pursuit of live kidney donation. We will evaluate the effectiveness of these interventions by conducting a randomized controlled trial in which patients on the deceased donor waiting list receive 1) usual care while on the transplant waiting list, 2) the educational and social worker intervention, or 3) the educational and social worker intervention plus the option of participating in the financial assistance program. The primary outcome of the randomized controlled trial will measure potential recipients' live kidney donor activation (a composite rate of live donor inquiries, completed new live donor evaluations, or live kidney donation) at 1 year. The TALKS study will rigorously assess the effectiveness of promising interventions to reduce race disparities in LDKT. NCT02369354.

  14. Evolution of deceased organ donation activity vs. efficiency over a 15 year period: an international comparison. (United States)

    Weiss, Julius; Elmer, Andreas; Mahíllo, Beatriz; Domínguez-Gil, Beatriz; Avsec, Danica; Costa, Alessandro Nanni; Haase-Kromwijk, Bernadette J J M; Laouabdia, Karim; Immer, Franz F


    The donation rate (DR) per million population is not ideal for an efficiency comparison of national deceased organ donation programs. The DR does not account for variabilities in the potential for deceased donation which mainly depends on fatalities from causes leading to brain death. In this study, the donation activity was put into relation to the mortality from selected causes. Based on that metric, this study assesses the efficiency of different donation programs. This is a retrospective analysis of 2001-2015 deceased organ donation and mortality registry data. Included are 27 Council of Europe countries, as well as the USA. A donor conversion index (DCI) was calculated for assessing donation program efficiency over time and in international comparisons. According to the DCI and of the countries included in the study, Spain, France, and the USA had the most efficient donation programs in 2015. Even though mortality from the selected causes decreased in most countries during the study period, differences in international comparisons persist. This indicates that the potential for deceased organ donation and its conversion into actual donation is far from being similar internationally. Compared with the DR, the DCI takes into account the potential for deceased organ donation, and therefore is a more accurate metric of performance. National donation programs could optimize performance by identifying the areas where most potential is lost, and by implementing measures to tackle these issues.

  15. Motivations for Deceased Organ Donation Among Volunteers in China: A Qualitative Research Study. (United States)

    Yin, Zhike; Liu, Shan; Yan, Jin; Liu, Jia


    BACKGROUND To align with guiding principles on human organ and tissue transplantation published by the World Health Organization (WHO), the Red Cross Society of China (RCSC) launched a new nationwide organ donation program in 2010 to recruit organ donation volunteers. Despite severe shortage of donated organs, there is a very low rate of volunteering for organ donation among the Chinese population (only 0.03 donors per million population) in the national program. Motivating organ donation is the key to the success of organ transplantation in China. MATERIAL AND METHODS Semi-structured 45- to 60-min interviews were conducted among 34 volunteers. Data analysis was performed with Nvivo 8.0 software. RESULTS Six motivations for organ donation were identified: helping others/altruism, fulfilling long-cherished wishes, reducing the burdens, making the best use of everything, giving back to society, and life extension. Factors affecting the motivation of organ donation among volunteers in China included traditional values, personal experiences, role model effect, family support, and problems in the donation system. Possible strategies to improve organ donation included fostering a scientific concept of the body and death, focusing donation promotion efforts on certain groups, and simplifying the process of organ donation. CONCLUSIONS There are multiple reasons for Chinese people to register for organ donation, with helping others as the central motivation.

  16. Empathy, social media, and directed altruistic living organ donation. (United States)

    Moorlock, Greg; Draper, Heather


    In this article we explore some of the ethical dimensions of using social media to increase the number of living kidney donors. Social media provides a platform for changing non-identifiable 'statistical victims' into 'real people' with whom we can identify and feel empathy: the so-called 'identifiable victim effect', which prompts charitable action. We examine three approaches to promoting kidney donation using social media which could take advantages of the identifiable victim effect: (a) institutionally organized campaigns based on historical cases aimed at promoting non-directed altruistic donation; (b) personal case-based campaigns organized by individuals aimed at promoting themselves/or someone with whom they are in a relationship as a recipient of directed donation; (c) institutionally organized personal case-based campaigns aimed at promoting specific recipients for directed donation. We will highlight the key ethical issues raised by these approaches, and will argue that the third option, despite raising ethical concerns, is preferable to the other two. © 2018 The Authors Bioethics Published by John Wiley & Sons Ltd.

  17. Human body donation in Thailand: Donors at Khon Kaen University. (United States)

    Culture, society and spirituality contribute to variability in the characteristics of human body donors and donation programmes worldwide. The donors and the body donation programme at Khon Kaen University, northeast Thailand, reflect all these aspects of Thailand, including the status accorded to the donors and the ceremonial acknowledgement of the donors and their families. Data from the programme records and from surveys of samples of currently registering donors and recently received donor bodies are analysed to define the characteristics of both registering and received donors, including motivation, demography, socio-economic status, health, and use of the bodies. The body donation programme at Khon Kaen University currently has a very high rate of registration of body donors, with gender and age differences in the patterns of donation. Registrants include more females than males, a long-standing pattern, and are an average age of 50 years. The bodies of 12% of registrants are received after death and include more males than females. Both sexes are of an average age of 69 years. Males had registered their donation eight years prior to death and females ten years prior. Current registrants identified altruistic motives for their decision to donate, although the coincidence of body donation by a highly revered monk with a surge in donations in 2015 suggests that Buddhism plays a primary role in motivation. The opportunity to make merit for donors and their families, and respect shown to donors and the nature of the ceremonies acknowledging the donors and their families, including the use of the Royal Flame at the cremation ceremony, all contribute to decisions to donate. The characteristics of body donors and the body donation programme at Khon Kaen University are reflective of Thai society and the centrality of Buddhism to Thai culture.

    Israni, A K; Zaun, D; Rosendale, J D; Snyder, J J; Kasiske, B L


    The status of deceased organ donation is assessed using several metrics, including donation/conversion rate (how often at least one organ is recovered for transplant from an eligible death), organ yield (ratio of observed/expected numbers of organs transplanted), and rate of organs discarded (number of organs discarded divided by the number of organs recovered for transplant). The 2012 donation/conversion rate was 72.5. eligible donors per 100 eligible deaths, slightly lower than the 2011 rate but higher than in previous years. The 2011-2012 yield ratio varied by donation service area from 0.91 (fewer organs transplanted per donor than expected) to 1.09 (more than expected), and also varied for specific organs. The mean number of organs transplanted per donor in 2012 was 3.02, lower than in 2011 and 2010; this number varied by donation service area from 2.04 to 3.76. The number of organs discarded is calculated by subtracting the number of organs transplanted from the number recovered for transplant; this number is used to calculate the discard rate. The discard rate in 2012 for all organs combined was 0.14 per recovered organ, slightly higher than in 2011 and 2011; it varied by donation service area and organ type. © Copyright 2013 The American Society of Transplantation and the American Society of Transplant Surgeons.

  19. Religious perspectives on organ donation. (United States)

    Gillman, J


    A donor's or family's religious beliefs are to be ascertained in discussions about organ donation. The positions of the major faith groups about donation are reviewed, leading to the conclusion that the large majority of faiths take a positive stance toward donation. Other factors such as the emotional response, the cultural values, and the spiritual issues may be even more compelling for family members than religious beliefs. Conflicts between one's personal beliefs and the position of one's faith group about donation are to be assessed and processed.

  1. Improving the Outcomes of Organs Obtained From Controlled Donation After Circulatory Death Donors Using Abdominal Normothermic Regional Perfusion. (United States)

    Miñambres, E; Suberviola, B; Dominguez-Gil, B; Rodrigo, E; Ruiz-San Millan, J C; Rodríguez-San Juan, J C; Ballesteros, M A


    The use of donation after circulatory death (DCD) has increased significantly during the past decade. However, warm ischemia results in a greater risk for transplantation. Indeed, controlled DCD (cDCD) was associated with inferior outcomes compared with donation after brain death. The use of abdominal normothermic regional perfusion (nRP) to restore blood flow before organ recovery in cDCD has been proposed as better than rapid recovery to reverse the effect of ischemia and improve recipients' outcome. Here, the first Spanish series using abdominal nRP as an in situ conditioning method is reported. A specific methodology to avoid restoring circulation to the brain after death determination is described. Twenty-seven cDCD donors underwent abdominal nRP during at least 60 min. Thirty-seven kidneys, 11 livers, six bilateral lungs, and one pancreas were transplanted. The 1-year death-censored kidney survival was 91%, and delayed graft function rate was 27%. The 1-year liver survival rate was 90.1% with no cases of ischemic cholangiopathy. Transplanted lungs and pancreas exhibited primary function. The use of nRP may represent an advance to increase the number and quality of grafts in cDCD. Poor results in cDCD livers could be reversed with nRP. Concerns about restoring brain circulation after death are easily solved. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Organ donation after cardiac death (DCD) is not optimal but still remains a valuable source of organ donation in trauma donors. The aim of this study was to assess national trends in DCD from trauma patients. A 12-year (2002 to 2013) retrospective analysis of the United Network for Organ Sharing database was performed. Outcome measures were the following: proportion of DCD donors over the years and number and type of solid organs donated. DCD resulted in procurement of 16,248 solid organs from 8,724 donors. The number of organs donated per donor remained unchanged over the study period (P = .1). DCD increased significantly from 3.1% in 2002 to 14.6% in 2013 (P = .001). There was a significant increase in the proportion of kidney (2002: 3.4% vs 2013: 16.3%, P = .001) and liver (2002: 1.6% vs 2013: 5%, P = .041) donation among DCD donors over the study period. DCD from trauma donors provides a significant source of solid organs. The proportion of DCD donors increased significantly over the last 12 years. Copyright © 2015 Elsevier Inc. All rights reserved.

  3. Determination of single-kidney glomerular filtration rate (GFR) with CT urography versus renal dynamic imaging Gates method

    To present a single-kidney CT-GFR measurement and compare it with the renal dynamic imaging Gates-GFR. Thirty-six patients with hydronephrosis referred for CT urography and 99mTc-DTPA renal dynamic imaging were prospectively included. Informed consent was obtained from all patients. The CT urography protocol included non-contrast, nephrographic, and excretory phase imaging. The total CT-GFR was calculated by dividing the CT number increments of the total urinary system between the nephrographic and excretory phase by the products of iodine concentration in the aorta and the elapsed time, then multiplied by (1- Haematocrit). The total CT-GFR was then split into single-kidney CT-GFR by a left and right kidney proportionality factor. The results were compared with single-kidney Gates-GFR by using paired t-test, correlation analysis, and Bland-Altman plots. Paired difference between single-kidney CT-GFR (45.02 ± 13.91) and single-kidney Gates-GFR (51.21 ± 14.76) was 6.19 ± 5.63 ml/min, p<0.001, demonstrating 12.1% systematic underestimation with ±11.03 ml/min (±21.5%) measurement deviation. A good correlation was revealed between both measurements (r=0.87, p<0.001). The proposed single-kidney CT-GFR correlates and agrees well with the reference standard despite a systematic underestimation, therefore it could be a one-stop-shop for evaluating urinary tract morphology and split renal function.

    To measure reliable glomerular filtration rate by using the representative values of transplanted renal depths, which are measured with ultrasonography. We included 54 patients (26 men, 28 women), with having both renal scintigraphy and ultrasonography after renal transplantation. We measured DFR with Gates' method using the renal depth measured by ultrasonography, and median and mean ones in each patient. We compared GFR derived from ultrasonography-measured renal depth with GFR derived from median and mean renal depths. The correlation coefficients were obtained among GFR derived from ultrasonography-measured renal depths, median and mean renal depth under linear regression analysis. We determined whether GFR derived from median or mean renal depth could substitute GFR derived from ultrasonography-measured renal depth with Bland-Altman method. We analyze the expected errors of the GFR using representative renal depth in terms of age, sex, weight, height, creatinine value, and body surface. The transplanted renal depths range from 3.20 cm to 5.96 cm. The mean value and standard deviation of renal depths measured by ultrasonography are 4.09±0.65 cm in men, and 4.24±0.78 cm in women. The median value of renal depths measured by ultrasonography is 4.36 cm in men and 4.14 cm in women. The GFR derived from median renal depth is more consistent with GFR derived from ultrasonography-measured renal depth than GFR derived from mean renal depth. Differences of GFR derived from median and ultrasonography-measured renal depth are not significantly different in the groups classified with creatinine value, age, sex, height, weight and body surface. When median value is adapted as a representative renal depth, we could obtain reliable GFR in transplanted kidney simply

  6. The cost-effectiveness of using payment to increase living donor kidneys for transplantation. (United States)

    Barnieh, Lianne; Gill, John S; Klarenbach, Scott; Manns, Braden J


    For eligible candidates, transplantation is considered the optimal treatment compared with dialysis for patients with ESRD. The growing number of patients with ESRD requires new strategies to increase the pool of potential donors. Using decision analysis modeling, this study compared a strategy of paying living kidney donors to waitlisted recipients on dialysis with the current organ donation system. In the base case estimate, this study assumed that the number of donors would increase by 5% with a payment of $10,000. Quality of life estimates, resource use, and costs (2010 Canadian dollars) were based on the best available published data. Compared with the current organ donation system, a strategy of increasing the number of kidneys for transplantation by 5% by paying living donors $10,000 has an incremental cost-savings of $340 and a gain of 0.11 quality-adjusted life years. Increasing the number of kidneys for transplantation by 10% and 20% would translate into incremental cost-savings of $1640 and $4030 and incremental quality-adjusted life years gain of 0.21 and 0.39, respectively. Although the impact is uncertain, this model suggests that a strategy of paying living donors to increase the number of kidneys available for transplantation could be cost-effective, even with a transplant rate increase of only 5%. Future work needs to examine the feasibility, legal policy, ethics, and public perception of a strategy to pay living donors.

    Environmental toxin/s is alleged to be the contributory factor for the chronic kidney disease of unknown aetiology (CKDu) in Sri Lanka. The potential of drinking water as a medium for the nephrotoxic agents in the affected subjects has been comprehensively discoursed in the recent past. The present study was aimed to assess the effect of replacing the habitual drinking water on the kidney function of CKDu patients residing in the North Central Province of Sri Lanka: METHODS: An interventional study was carried out to assess the disease progression rate of a CKDu population whose habitual drinking water was replaced by bottled spring water certified by Sri Lanka Standard (SLS) for a period of 18 month along with a population of CKDu patients who continued with their usual drinking water. Kidney function of subjects in both groups were monitored in terms of blood pressure, serum creatinine, serum calcium, serum phosphorus, hemoglobin, estimated glomerular filtration rate and urinary protein at 6 months intervals during the intervention and follow up periods. Diminished disease progression rate was observed in CKDu patients in the intervention group when compared with the non- intervention group based on serum creatinine, Hb, estimated glomerular filtration rate and urinary protein levels. Extensive interventional studies are required to generalize effect of drinking water on CKDu population. The habitual drinking water is likely to be a contributory factor towards the progression of the disease. © 2017 Asian Pacific Society of Nephrology.

  8. Use of Lithium and Anticonvulsants and the Rate of Chronic Kidney Disease: A Nationwide Population-Based Study. (United States)

    Kessing, Lars Vedel; Gerds, Thomas Alexander; Feldt-Rasmussen, Bo; Andersen, Per Kragh; Licht, Rasmus W


    Lithium is the main mood stabilizing drug for bipolar disorder. However, it is controversial whether long-term maintenance treatment with lithium or other drugs for bipolar disorder causes chronic kidney disease (CKD). To compare rates of CKD and in particular rates of end-stage CKD among individuals exposed to successive prescriptions of lithium, anticonvulsants, or other drugs used for bipolar disorder. This is a Danish nationwide population-based study of 2 cohorts. Cohort 1 comprised a randomly selected sample of 1.5 million individuals among all persons who were registered in Denmark on January 1, 1995, all patients with a diagnosis of a single manic episode or bipolar disorder between January 1, 1994, and December 31, 2012 (n =10,591), and all patients exposed to either lithium (n = 26,731) or anticonvulsants (n=420,959). Cohort 2 included the subgroup of 10,591 patients diagnosed as having bipolar disorder. Possible CKD, definite CKD, and end-stage CKD (defined as long-term dialysis or renal transplantation). A total of 14,727 (0.8%), 18,762 (1.0%), and 3407 (0.2%) in cohort 1 and 278 (2.6%), 319 (3.0%), and 62 (0.6%) in cohort 2 were diagnosed as having possible, definite, or end-stage CKD, respectively. Based on the total sample and not considering diagnoses, use of lithium was associated with an increased rate of definite CKD (0 prescriptions: hazard ratio [HR] = 1.09, 95% CI, 0.81-1.45; ≥60 prescriptions: HR = 3.65, 95% CI, 2.64-5.05; P for trend anticonvulsants, antipsychotics, or antidepressants was not. Neither use of lithium nor use of any other drug class was associated with increasing rates of end-stage CKD. In patients with bipolar disorder, use of lithium was associated with an increased rate of definite CKD (1-2 prescriptions: HR = 0.89, 95% CI, 0.39-2.06; ≥60 prescriptions: HR = 2.54, 95% CI, 1.81-3.57; P for trend anticonvulsants (definite CKD, 1-2 prescriptions: HR = 1.23, 95% CI, 0.76-1.99; ≥60

  9. Organ Donation in the 50+ Age Demographic: Survey Results on Decision Rationale and Information Preferences. (United States)

    Tartaglia, Alexander; Dodd-McCue, Diane; Myer, Kevin A; Mullins, Andrew


    The rate of organ donation by older potential donors is significantly declining even though recent studies show positive clinical outcomes with organs transplanted from older donors. This study examined the 50+ age demographic to identify the rationale for donation decisions, preferred media methods of donation information delivery, and responsiveness to an age-tailored donation message. Results from 579 surveys, 87% from the 50+ age demographic, found respondents prone to self-select themselves as medically ineligible based on current medication and health status, even though they might be medically suitable donors. Their incentive to pursue additional information on donation is limited except when motivated by personal accounts within their families and communities. In addition, even when computer literate, they continue to favor the printed or spoken word for donation information delivery. The results suggest an opportunity for those working with older adults to develop more personalized, localized donation education programs targeting this age demographic. © The Author(s) 2014.

    Organ shortage is the major limitation to kidney transplantation in the developed world. Conversely, millions of patients in the developing world with end-stage renal disease die because they cannot afford renal replacement therapy-even when willing living kidney donors exist. This juxtaposition between countries with funds but no available kidneys and those with available kidneys but no funds prompts us to propose an exchange program using each nation's unique assets. Our proposal leverages the cost savings achieved through earlier transplantation over dialysis to fund the cost of kidney exchange between developed-world patient-donor pairs with immunological barriers and developing-world patient-donor pairs with financial barriers. By making developed-world health care available to impoverished patients in the developing world, we replace unethical transplant tourism with global kidney exchange-a modality equally benefitting rich and poor. We report the 1-year experience of an initial Filipino pair, whose recipient was transplanted in the United states with an American donor's kidney at no cost to him. The Filipino donor donated to an American in the United States through a kidney exchange chain. Follow-up care and medications in the Philippines were supported by funds from the United States. We show that the logistical obstacles in this approach, although considerable, are surmountable. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

    Complementary and alternative medicine is a broad field of health including all health care practices and methods; and their accompanying theories and beliefs. In the present study, we aimed to examine the frequency of complementary-alternative medicine use, and its relation with glomerular filtration rate and depression in patients with chronic kidney disease at predialysis stage. A total of 1053 predialysis patients; 518 female and 535 male, that were followed up with chronic kidney disease for at least 3 months were enrolled into the study. Demographic features, biochemical parameters and findings of physical examination were recorded. Their compliance to diet, and knowledge about disease were questioned. Beck depression inventory and questionnaire regarding to complementary-alternative medicine use were performed. The overall frequency of complementary-alternative medicine use was 40.3% . Total ratio of herbal products was 46%. Complementary-alternative medicine use was significantly more frequent in female or single patients, and patients that informed about chronic kidney disease or under strict diet (p:0.007, p:0.016, p:0.02, p:0.016; respectively). When glomerular filtration rate of participants were considered, complementary-alternative medicine use was similar in different stages of kidney disease. Depression was observed in 41.9% of patients and significantly frequent in patients with alternative method use (p:0.002). Depression score was higher as creatinine increases and glomerular filtration rate decreases (p:0.002; r: 0,093). We determined that complementary-alternative medicine use gradually increases at predialysis stage as glomerular filtration rate decreases and there is a strict relation between complementary-alternative medicine use and depression or female gender. Disorder related stressors may lead to seeking of alternative methods. This article is protected by copyright. All rights reserved.

  15. Risk Behavior and Reciprocity of Organ Donation Attitudes in Young Men. (United States)

    Vetterli, D C M; Lava, S A G; Essig, S; Milosevic, G; Cajöri, G; Uehlinger, D E; Moor, M B


    Lack of donor organs remains a major obstacle in organ transplantation. Our aim was to evaluate (1) the association between engaging in high-risk recreational activities and attitudes toward organ donation and (2) the degree of reciprocity between organ acceptance and donation willingness in young men. A 17-item, close-ended survey was offered to male conscripts ages 18 to 26 years in all Swiss military conscription centers. Predictors of organ donation attitudes were assessed in bivariate analyses and multiple logistic regression. Reciprocity of the intentions to accept and to donate organs was assessed by means of donor card status. In 1559 responses analyzed, neither motorcycling nor practicing extreme sports reached significant association with donor card holder status. Family communication about organ donation, student, or academic profession and living in a Latin linguistic region were predictors of positive organ donation attitudes, whereas residence in a German-speaking region and practicing any religion predicted reluctance. Significantly more respondents were willing to accept than to donate organs, especially among those without family communication concerning organ donation. For the first time, it was shown that high-risk recreational activities do not influence organ donation attitudes. Second, a considerable discrepancy in organ donation reciprocity was identified. We propose that increasing this reciprocity could eventually increase organ donation rates. Copyright © 2015 Elsevier Inc. All rights reserved.

  16. The Influence of Neighbor Effect and Urbanization Toward Organ Donation in Thailand. (United States)

    Wongboonsin, Kua; Jindahra, Pavitra; Teerakapibal, Surat


    Toward population wellness, an extreme scarcity of organ supply is proven to be an enormous hindrance. Preferences toward organ donation are vital to raise the organ donation rate. Notably, the area people live in can address the social influence on individual preference toward organ donation. This article studies the impact of the neighbor effect on organ donation decisions, addressing the social influence of urbanization on preferences. How neighborhood-specific variables, population density, and socioeconomic status drive the neighbor effect is investigated. The pursuit of organ donor traits is to be answered. The study uses organ donation interview survey data and neighborhood-specific data from Thailand to estimate a series of logistic regression models. Individuals residing in urban areas exhibit a greater likelihood to sign the donor card than those in rural areas. The neighborhood socioeconomic status is the key driver. An individual is more willing to be an organ donor when having neighbors with higher socioeconomic statuses. Results also reveal positive influences of males and education on the organ donation rate. This article documents the "neighbor effect" on the organ donation decision via living area type, offering an alternative exposition in raising the organ donation rate. In shifting the society norm toward organ donation consent, policy-makers should acknowledge the benefit of urbanization on organ donation decision derived from resourceful urban areas. Moreover, raising education levels does improve not only citizens' well-being but also their tendency to exhibit an altruistic act toward others.

  17. The difference in the attitude of Chinese and Japanese college students regarding deceased organ donation. (United States)

    Liu, S; Liu, C; Cao, X; Shang, B; Chen, A; Liu, B


    Under the influence of traditional oriental culture, the lack of organ donation is especially serious in China and Japan. The aim of this study was to compare Chinese and Japanese college students' attitudes and analyze contributing factors toward deceased donation. An anonymous, self-administered questionnaire comprising 15 questions was distributed to approximately 400 college students at Liaoning University, China, and Kyushu University, Japan. Statistical analysis used SPSS software. Japanese students' attitude towards deceased organ donation was more favorable than that of Chinese students (43.6% versus 35.9%, P = .001). Several factors contributed to positive responses by students from both countries: family perspective on organ donation and transplantation; decision to donate to family members; prior blood donation; living liver or kidney donation; possibility of needing a transplant; and willingness to receive a deceased or a living donor organ. More efforts must emphasize awareness and up-to-date knowledge regarding organ donation among citizens and should be undertaken by the Chinese and Japanese governments. Copyright © 2013 Elsevier Inc.

  18. Arterial wave reflections and kidney function decline among persons with preserved estimated glomerular filtration rate: the Multi-Ethnic Study of Atherosclerosis. (United States)

    Hsu, Jeffrey J; Katz, Ronit; Chirinos, Julio A; Jacobs, David R; Duprez, Daniel A; Peralta, Carmen A


    Differences in arterial wave reflections have been associated with increased risk for heart failure and mortality. Whether these measures are also associated with kidney function decline is not well established. Reflection magnitude (RM, defined as the ratio of the backward wave [Pb] to that of the forward wave [Pf]), augmentation index (AIx), and pulse pressure amplification (PPA) were derived from radial tonometry measures among 5232 participants free of cardiovascular disease who were enrolled in the Multiethnic Study of Atherosclerosis. Kidney function was estimated by creatinine and cystatin C measurements, as well as albumin-to-creatinine ratio. We evaluated the associations of Pb, Pf, RM, AIx, and PPA with annualized estimated glomerular filtration rate (eGFR) change and rapid kidney function decline over 5 years, using generalized linear mixed models and logistic regression, respectively. Of the study participants, 48% were male, mean age was 62 years, mean eGFR and median albumin-to-creatinine ratio at baseline were 84 mL/min/1.73 m(2) and 5.3 mg/g, respectively. In demographically adjusted models, both Pb and Pf had similarly strong associations with kidney function decline; compared to those in the lowest tertiles, the persons in the highest tertiles of Pb and Pf had a 1.01 and 0.99 mL/min/1.73 m(2)/year faster eGFR decline, respectively (P function decline. In conclusion, the reflected and forward wave components were similarly associated with kidney function decline, and these associations were explained by differences in systolic blood pressure.

  19. The doctor-patient relationship in living donor kidney transplantation. (United States)

    Danovitch, Gabriel M


    A therapeutic and effective doctor-patient relationship and patient-doctor relationship is at the core of all successful medical care. The medical and psychological evaluation of a potential kidney donor serves to protect the long-term health of both the donor and the potential recipient. Careful assessment of risk and donor education is at the core of donor evaluation and the decision to progress with donation requires refined clinical judgment by the medical team and critical thinking by the donor. Increasing pressure to increase the numbers of living donor transplants and suggestions by some that the process should be commercialized make it timely to consider the nature of the relationship between the doctor and the patient in the unusual circumstance of living donation. A high rate of complications in recipients of purchased kidneys and a lack of knowledge of the fate of paid donors have been reported. Commercialization of transplantation undermines the therapeutic doctor-patient relationship and threatens the healthy development of the international transplant endeavor.

    Low organ donation rates remain a major barrier to organ transplantation. We aimed to determine the effect of a video and patient cueing on organ donation consent among patients meeting with their primary care provider. This was a randomized controlled trial between February 2013 and May 2014. The waiting rooms of 18 primary care clinics of a medical system in Cuyahoga County, Ohio. The study included 915 patients over 15.5 years of age who had not previously consented to organ donation. Just prior to their clinical encounter, intervention patients (n = 456) watched a 5-minute organ donation video on iPads and then choose a question regarding organ donation to ask their provider. Control patients (n = 459) visited their provider per usual routine. The primary outcome was the proportion of patients who consented for organ donation. Secondary outcomes included the proportion of patients who discussed organ donation with their provider and the proportion who were satisfied with the time spent with their provider during the clinical encounter. Intervention patients were more likely than control patients to consent to donate organs (22 % vs. 15 %, OR 1.50, 95%CI 1.10-2.13). Intervention patients were also more likely to have donation discussions with their provider (77 % vs. 18 %, OR 15.1, 95%CI 11.1-20.6). Intervention and control patients were similarly satisfied with the time they spent with their provider (83 % vs. 86 %, OR 0.87, 95%CI 0.61-1.25). How the observed increases in organ donation consent might translate into a greater organ supply is unclear. Watching a brief video regarding organ donation and being cued to ask a primary care provider a question about donation resulted in more organ donation discussions and an increase in organ donation consent. Satisfaction with the time spent during the clinical encounter was not affected. Identifier: NCT01697137.

  2. Regional Differences in Communication Process and Outcomes of Requests for Solid Organ Donation. (United States)

    Traino, H M; Molisani, A J; Siminoff, L A


    Although federal mandate prohibits the allocation of solid organs for transplantation based on "accidents of geography," geographic variation of transplantable organs is well documented. This study explores regional differences in communication in requests for organ donation. Administrative data from nine partnering organ procurement organizations and interview data from 1339 family decision makers (FDMs) were compared across eight geographically distinct US donor service areas (DSAs). Authorization for organ donation ranged from 60.4% to 98.1% across DSAs. FDMs from the three regions with the lowest authorization rates reported the lowest levels of satisfaction with the time spent discussing donation and with the request process, discussion of the least donation-related topics, the highest levels of pressure to donate, and the least comfort with the donation decision. Organ procurement organization region predicted authorization (odds ratios ranged from 8.14 to 0.24), as did time spent discussing donation (OR = 2.11), the number of donation-related topics discussed (OR = 1.14), and requesters' communication skill (OR = 1.14). Standardized training for organ donation request staff is needed to ensure the highest quality communication during requests, optimize rates of family authorization to donation in all regions, and increase the supply of organs available for transplantation. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

  5. Mass media, online social network, and organ donation: old mistakes and new perspectives. (United States)

    Aykas, A; Uslu, A; Şimşek, C


    Contrary to TV programs projecting awareness about organ donation in society, concrete evidence exists about adverse influence of negative broadcasts on organ donation rates. We sought to determine the effect of mass media on public opinion toward organ donation and the efficacy of public campaigns and novel social media attempts on donation rates. We conducted a systematic review of relevant literature and national campaign results. Hoaxes about brain death and organ transplantation adversely affect organ donation rates in both Western and Eastern societies. Scientifically controversial and exaggerated press conferences and institutional advertisements create mistrust in doctors, thus reducing organ donation. The overall effect of public education campaigns in promoting organ donation is a temporary 5% gain. Increments in organ donation rates is expected with novel applications of social media (Facebook effect). Communication, based on mutual trust, must be established between medicine and the media. Continuing education programs with regard to public awareness on organ donation should be conducted over social media. Copyright © 2015 Elsevier Inc. All rights reserved.

  7. Concern for Lost Income Following Donation Deters Some Patients From Talking to Potential Living Donors. (United States)

    Rodrigue, James R; Schold, Jesse D; Mandelbrot, Didier A; Taber, David J; Phan, Van; Baliga, Prabhakar K


    Some living kidney donors report lost income during recovery from surgery. Little is known about whether concern for living donor's lost income affects the decision to undergo donation evaluation and the willingness of transplant candidates to discuss living kidney donation (LKD) with others. To examine whether transplant patients were told by potential donors about lost income concerns and whether patients chose not to discuss LKD with others due to lost income concerns. Kidney transplant patients (185 wait-listed candidates, 171 deceased donor recipients, and 100 live donor recipients) at 2 centers completed a questionnaire to assess whether concern about donor's lost income was a consideration in discussion about LKD with others. One-third (32%) were told by a family member/friend that they were willing to donate but were concerned about potential lost income. The majority of those who expressed financial concern (64%) did not initiate donation evaluation. Many patients (42%) chose not to discuss living donation with a family member/friend due to concern about the impact of lost income on the donor. In the multivariable model, lower annual household income was the only statistically significant predictor of both having a potential donor expressing lost income concern and choosing not to talk to someone because of lost income concern. Findings from the current study underscore how concern about income loss for living donors may affect decision-making by both transplant candidates and potential donors.

    This study applies a threshold model proposed by to analyze the diffusion process of donating behavior for renewable energy. We first use a stated preference survey to estimate the determinants of a decision to support the donation scheme under various predicted participation rates. Using the estimated coefficients, we simulate how herd behavior spreads and the participation rate reaches the equilibrium. The participation rate at the equilibrium is estimated as 37.88% when the suggested donation is 500 yen, while it is 17.76% when the suggested amount is 1000 yen. The influence of environmentalism and altruism is also examined, and we find that these motivations increase the participation rate by 31.51% on average.

  9. The PIERDUB project: International Project on Education and Research in Donation at University of Barcelona: training university students about donation and transplantation. (United States)

    Manyalich, M; Paredes, D; Ballesté, C; Menjívar, A


    Donation and transplantation is an accepted therapeutic option when organ failure or tissue replacements are needed to save or improve the quality of life. However, in most medical schools there is no specific training for it, thus disregarding the key role of university students for the future success of the process. Knowledge diffusion about the donation procedure to clarify doubts and stimulate positive attitudes toward donation. Training university students in the donation and transplantation process. Research about the previous donation knowledge and the impact in donation indexes. Three different phases have been designed: (1) Training the University of Barcelona Health Sciences School students; (2) Training the Health Sciences School students in other faculties of Catalonia, Spain, and International; and (3) research. Since 2005, we have offered yearly an Optional Credits Course to medical students with duration of 45 hours, and two Donation days opened to health sciences students. Since 2007, promotional campaigns have been carried out in medicine and other health sciences faculties. Until now, 818 answered surveys have been collected to evaluate previous knowledge among university students. Training medical and other health sciences students in the donation process will improve quality of medical education and develop a trainer role for future professionals to help improve donation rates.

  10. Donating in good faith or getting into trouble Religion and organ donation revisited. (United States)

    Oliver, Mike; Ahmed, Aimun; Woywodt, Alexander


    There is worldwide shortage of organs for solid-organ transplantation. Many obstacles to deceased and live donation have been described and addressed, such as lack of understanding of the medical process, the issue of the definition of brain death, public awareness of the need for transplants, and many others. However, it is clear that the striking differences in deceased and live donation rates between different countries are only partly explained by these factors and many cultural and social reasons have been invoked to explain these observations. We believe that one obstacle to both deceased and live donation that is less well appreciated is that of religious concerns. Looking at the major faiths and religions worldwide, it is reassuring to see that most of them encourage donation. However, there is also scepticism amongst some of them, often relating to the concept of brain death and/or the processes surrounding death itself. It is worthwhile for transplant teams to be broadly aware of the issues and also to be mindful of resources for counselling. We believe that increased awareness of these issues within the transplant community will enable us to discuss these openly with patients, if they so wish.

  13. Correlation of glomerular filtration rate measurement using Tc-99m DTPA with cystatin-C levels and creatinine clearance for staging of chronic kidney disease

    International Nuclear Information System (INIS)

    Elliyanti, A.; Iskandar, Azmi S.


    Full text: The presence of Chronic Kidney Disease (CKD) was established based on kidney damage presence and the level of kidney function through Glomerular filtration rate (GFR). It was also recognized that renal scintigraphy (renogram) using TC-99m DTPA (diethylenetriamine pentacetic acid) has advantages in the measurement of GFR. Recently, serum Cystatin-C is proposed as the new marker of GFR. The aim of this study is to find out the correlation of GFR, derived from renogram, with Cystatin- C levels and Creatinine Clearance (CC) in CKD. Material and Methods: A total of 30 subjects (age mean is 60.8 years, 21 males and 9 females) were enrolled in this study with diagnosis stage 2 of CKD. CKD staging was determined by Cockroft-Gault (CG) equation, taking into account the serum creatinine. Renogram was performed using a single head camera with IV administration of 5 mCi DTPA. Cystatin-C and creatinine clearance (24-hours urine samples) were include in this study. Results: The mean GFR of renogram, Cystatin-C, CC and CG are 64.96 ml/min/1.73m2 (SD 28.047), 53.37 ml/min/1.73m2 (SD 21.29), 58.09 ml/min/1.73m2 (SD 35.45), 46.00 ml/min/1.73m2 (SD 12.06) respectively. There is better correlation between renogram and Cystatin-C (r=0.585, p0.0007) compared renogram and CC (r=0.388, p=0.03) or renogram and CG (r=-0.029, p=0.87). Conclusion: Cystatin-C shows better indicator of GFR than CC and CG. Serum creatinine concentration alone should not be used to assess the level of kidney function in the staging of CKD. (author)

    Tumin, Makmor; Noh, Abdillah; Mohd Satar, Nurulhuda; Chin-Sieng, Chong; Soo-Kun, Lim; Abdullah, Nawi; Kok-Peng, Ng


    The aim of this paper is to look into the factors influencing Malaysian Muslims' decision to become deceased organ donors in Malaysia. We approached 900 Malaysian Muslims and 779 participated in our survey, conducted in Kuala Lumpur and its suburb. We examined their willingness to become donors and the willing donors were asked why they did not pledge to become donors. Non-donors were asked why they refuse to become donors. The survey found the main reason for Malaysian Muslims not pledging their organs was due to their lack of information on organ donation and/or their lack of confidence in the government's ability to properly administer organ donation procedures. Another interesting finding is that religion is not a main deterrent to organ donation. The survey suggests that Malaysia can explore many ways to encourage organ donation without having to resort to the highly controversial financial incentive option. A key to Malaysia's success or failure to increase organ donation rate lies in its ability to persuade its Muslim population (its largest population) to donate organs. This can be done by adopting a segmented, focused, and highly localized form of public education and by leveraging on existing networks involving local religious and community leaders as well as government and non-governmental institutions.

  15. Organ and tissue donation in a regional paediatric intensive care unit: evaluation of practice. (United States)

    Carone, Laura; Alurkar, Shrirang; Kigozi, Phoebe; Vyas, Harish


    Approximately 2% of those on the organ transplant list in the UK are children. Early identification of donors and referral to organ donation teams (ODT) has proven to increase both the success rate of gaining consent and the number of organs actually retrieved. To evaluate the practice relating to organ donation for children receiving end-of-life care on a paediatric intensive care unit (PICU) measured against the National Guidelines. All children 0-18 who received their end-of-life care and died on the PICU. A retrospective cohort study of organ donation patterns including referral, approach, consent and donation. This involved a review of case notes on PICU between the years 2009 and 2014. One hundred five deaths were identified and 100 notes were examined and data analysed to ascertain if religion, age and length of stay on PICU impacted on practice. Eighty-six children met the early identification criteria for potential donors, 40 (46.5%) children were referred to the ODT and 33 (38.3%) families were approached regarding donation. Twenty-one (24.4%) families consented to donation. Seventeen donations took place with a total of 41 sets of organs/tissues retrieved. Despite the majority of children meeting early identification for potential donors, many were not being referred. All children on end-of-life care should be referred for potential organ donation. Organ donation needs to be seen as a priority for hospitals as a part of routine end-of-life care to help increase referral rates and give families the opportunity to donate. Many paediatric deaths are not referred for consideration of organ donation, despite guidelines stating that this process should be standard of care. Further optimization of referral rates may aid in increasing the number of organs available for donation. What is Known: • Shortage of organs continues to be a national problem. • NICE guidelines state that all patients who are on end-of-life care should have the option of organ donation

  16. Marginal kidney donor

    Full Text Available Renal transplantation is the treatment of choice for a medically eligible patient with end stage renal disease. The number of renal transplants has increased rapidly over the last two decades. However, the demand for organs has increased even more. This disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidneys and donors. We performed a Medline search to establish the current status of marginal kidney donors in the world. Transplant programs using marginal deceased renal grafts is well established. The focus is now on efforts to improve their results. Utilization of non-heart-beating donors is still in a plateau phase and comprises a minor percentage of deceased donations. The main concern is primary non-function of the renal graft apart from legal and ethical issues. Transplants with living donors outnumbered cadaveric transplants at many centers in the last decade. There has been an increased use of marginal living kidney donors with some acceptable medical risks. Our primary concern is the safety of the living donor. There is not enough scientific data available to quantify the risks involved for such donation. The definition of marginal living donor is still not clear and there are no uniform recommendations. The decision must be tailored to each donor who in turn should be actively involved at all levels of the decision-making process. In the current circumstances, our responsibility is very crucial in making decisions for either accepting or rejecting a marginal living donor.

  17. Minority donation in the United States: challenges and needs. (United States)

    Shaz, Beth H; Hillyer, Christopher D


    In the United States, blood donation rates of African-Americans are 25-50% of that of white individuals. As African-Americans make up an ever increasing and now substantial minority, and African-American recipients of blood transfusion, both specialized, such as sickle cell disease patients, and general hospitalized patients, have a better chance of receiving phenotype-matched or appropriate red blood cell units when there is a significant percentage of products in the inventory from African-American donors, it is important to understand the reason for the observed difference. Possible reasons for this discrepancy in donation rates include increased rates of donor deferral and ineligibility; increased barriers to donation, such as fear and distrust; and different marketing and education strategies. Thus, to increase the blood availability to African-American recipients, the reasons for these donation rate differences must be better understood and subsequently addressed through improved blood donor recruitment programs. The majority of African-American donor recruitment programs have focused on donating for sickle cell disease patients, particularly children, which have been of limited success. Significant improvements in African-American donor recruitment are needed to adequately meet the demand of African-American patients as well as the entire population.

  18. Physiological stress response patterns during a blood donation. (United States)

    Donating blood is associated with increased psychological stress. This study investigates whether a blood donation induces physiological stress and if response patterns differ by gender, donation experience and non-acute stress. In 372 donors, physiological stress [blood pressure, pulse rate, pulse rate variability (PRV)] was measured at seven moments during routine donation. PRV was assessed using time domain [root mean square of successive differences (RMSSD)] and frequency domain [high frequency (HF) and low frequency (LF) power] parameters. Non-acute stress was assessed by questionnaire. Shape and significance of time course patterns were assessed by fitting multilevel models for each stress measure and comparing men and women, first-time and experienced donors, and donors with high and low levels of non-acute stress. Significant response patterns were found for all stress measures, where levels of systolic blood pressure (F(1,1315) = 24·2, P blood pressure (F(1,1326) = 50·9, P blood pressure/pulse rate in women; higher pulse rate in first-time donors; higher RMSSD at arrival and from screening until leaving in first-time donors; and higher LF and HF in first-time donors. This study shows an increase in physiological stress related to needle insertion, followed by a decrease when leaving the donation centre. Some group effects were also found. © 2018 International Society of Blood Transfusion.

  19. Complex Contagion of Campaign Donations.

    Vincent A Traag

    Full Text Available Money is central in US politics, and most campaign contributions stem from a tiny, wealthy elite. Like other political acts, campaign donations are known to be socially contagious. We study how campaign donations diffuse through a network of more than 50,000 elites and examine how connectivity among previous donors reinforces contagion. We find that the diffusion of donations is driven by independent reinforcement contagion: people are more likely to donate when exposed to donors from different social groups than when they are exposed to equally many donors from the same group. Counter-intuitively, being exposed to one side may increase donations to the other side. Although the effect is weak, simultaneous cross-cutting exposure makes donation somewhat less likely. Finally, the independence of donors in the beginning of a campaign predicts the amount of money that is raised throughout a campaign. We theorize that people infer population-wide estimates from their local observations, with elites assessing the viability of candidates, possibly opposing candidates in response to local support. Our findings suggest that theories of complex contagions need refinement and that political campaigns should target multiple communities.

    Batool Y. Bosakhar


    Full Text Available Background and objectives: In Kuwait, information regarding public knowledge and attitudes towards organ donation are scanty. This study aimed to evaluate public knowledge and attitude regarding organ donation and determine factors which predict them. Methods: This cross-sectional study was conducted among 630 participants recruited from 27 randomly selected public cooperative societies and private supermarkets in Kuwait. A self-administered questionnaire was used to collect data. Results: The prevalence rate of knowledge about organ donation was 68%, with a significantly higher rate among females than males (73% vs. 63%, respectively, p = 0.01. A composite score of knowledge was also higher among females than males (8.4 ± 5.8 vs. 6.8 ± 5.8, respectively, p = 0.001. In multivariate analysis, female gender (OR = 1.7; 95% CI =1.2, 2.4 and an educational level of bachelor’s degree or higher (OR = 2.6, 95% CI = 1.7, 3.9 were significant predictors of the knowledge. Among the barriers, more females than males mentioned about the fear of the operative procedures (p<0.001 and complications after the surgery (p = 0.011. Overall, 73% accepted the idea of organ donation during life, and 67% actually opted for donating their organs during life. However, almost everybody wanted to donate organs to their relatives. Conclusion: The study identified factors predicting knowledge and attitude regarding organ donation. The results will help in planning how to improve the rate of donors in Kuwait.

  2. Laparoscopic adjustable gastric band in an obese unrelated living donor prior to kidney transplantation: a case report

    Directory of Open Access Journals (Sweden)

    Coombes Jeff S


    Full Text Available Abstract Introduction Obese living donors who undergo donor nephrectomy have higher rates of intra-operative and post-operative complications. Many centres exclude obese donors from living donor transplant programs. Diet, exercise and medication are often ineffective weight loss interventions for donors, hence bariatric surgery should be considered. Case presentation We report the case of a 53-year-old Caucasian woman who underwent laparoscopically adjustable gastric banding. The procedure enabled her to lose sufficient weight to gain eligibility for kidney donation. After losing weight, she had an uncomplicated laparoscopic donor nephrectomy surgery, and the recipient underwent successful kidney transplantation. Conclusion Laparoscopically adjustable gastric banding should be considered for obese potential living kidney donors whenever transplantation units restrict access to donor nephrectomy based on the increased surgical risk for donors.

  3. University students' knowledge of corneal donation and willingness to donate corneas in the occupied Palestinian territory: a cross-sectional study. (United States)

    Access to corneal transplantation is limited worldwide because of poor knowledge. Ethical, religious, and cultural barriers contribute to low rates of corneal donation. In the occupied Palestinian territory, limited information is available on factors affecting corneal donation. The aim of this study was to assess the knowledge and willingness towards corneal donation in Palestinian students. This cross-sectional study included university students selected through convenience sampling in Nablus in the summer of 2016. The sample size was determined using the sample formulae and a 15% non-response rate. All students registered in obligatory courses were included in the study after verbal consent. Each participant was given a self-administered questionnaire consisting of 14 questions to assess knowledge, awareness, and willingness toward corneal donation. Frequencies were used for descriptive analysis, and associations were determined using multivariate analysis and χ 2 test, with a p value of less than 0·05 considered significant. Of the 634 students completing the questionnaire, 411 (65%) were women, 614 (97%) were Muslims, and 155 (25%) were health or medical students. 592 (93%) respondents were unaware of eye bank availability, and 407 (69%; p=0.002) of these respondents did not show willingness towards corneal donation. 431 (67%) respondents were aware of a lack in corneal donation, but 274 (64%; p=0·01) of these respondents did not show willingness towards corneal donation. 429 (68%) respondents were not willing to donate their corneas, the most common reasons being disapproval by family members and poor awareness. We found no association between sociodemographic factors and willingness was determined. Palestinian students are aware of the lack of local cornea donation but are unwilling to donate their corneas. The study results are not representative of the entire population because of the homogeneous nature of the sample. Large efforts are needed locally to

  9. Organ donation in the ICU: A document analysis of institutional policies, protocols, and order sets. (United States)

    Oczkowski, Simon J W; Centofanti, John E; Durepos, Pamela; Arseneau, Erika; Kelecevic, Julija; Cook, Deborah J; Meade, Maureen O


    To better understand how local policies influence organ donation rates. We conducted a document analysis of our ICU organ donation policies, protocols and order sets. We used a systematic search of our institution's policy library to identify documents related to organ donation. We used Mindnode software to create a publication timeline, basic statistics to describe document characteristics, and qualitative content analysis to extract document themes. Documents were retrieved from Hamilton Health Sciences, an academic hospital system with a high volume of organ donation, from database inception to October 2015. We retrieved 12 active organ donation documents, including six protocols, two policies, two order sets, and two unclassified documents, a majority (75%) after the introduction of donation after circulatory death in 2006. Four major themes emerged: organ donation process, quality of care, patient and family-centred care, and the role of the institution. These themes indicate areas where documented institutional standards may be beneficial. Further research is necessary to determine the relationship of local policies, protocols, and order sets to actual organ donation practices, and to identify barriers and facilitators to improving donation rates.

  10. Reduced social preferences in autism: evidence from charitable donations. (United States)

    Lin, Alice; Tsai, Karin; Rangel, Antonio; Adolphs, Ralph


    People with autism have abnormal preferences, ranging from an apparent lack of preference for social stimuli to unusually strong preferences for restricted sets of highly idiosyncratic stimuli. Yet the profile of preferences across social and nonsocial domains has not been mapped out in detail, and the processes responsible remain poorly understood. To assess preferences across a range of stimuli, we measured real monetary donations to 50 charities spanning categories pertaining to people, mental health, animals, or the environment. We compared the donations made by 16 high-functioning adults with autism to those made by neurotypical controls matched on age, gender and education. We additionally collected ratings of how people evaluated the different charities. Compared with controls, high-functioning adults with autism donated less overall and also showed a significantly disproportionate reduction in donations to people charities compared with donations to the other charities. Furthermore, whereas controls discriminated strongly between different people charities, choosing to donate a lot of money to some and very little to others, much less discrimination was seen in the autism group. Ratings that probed how participants constructed their preferences did not differ between groups, except for a difference in the perceived impact of pictures and text information about people charities. Strikingly, there were some charities related to mental health, and autism in particular, to which the autism group donated considerably more than did the controls. People with autism were found to have reduced preference and sensitivity towards charities benefiting other people. The findings provide evidence for a domain-specific impairment in social cognition in autism spectrum disorder, and in particular in linking otherwise intact social knowledge to the construction of value signals on which preferences regarding other people are based.

  16. Study of living kidney donor-recipient relationships: variation with socioeconomic deprivation in the white population of England. (United States)

    Bailey, Phillippa K; Tomson, Charles Rv; Ben-Shlomo, Yoav


    Socioeconomic deprivation is associated with higher renal replacement therapy acceptance rates in the UK but lower rates of living kidney transplantation. This study examines donor-recipient relationship patterns with socioeconomic deprivation in the white population of England. Demographic characteristics of all white live renal transplant donors and recipients between 2001 and 2010 in England were analyzed. Patterns of donor-recipient relationship were analyzed to see whether they differed according to an ecological measure of socioeconomic status (Index of Multiple Deprivation). Group comparisons were performed using chi-square tests and multivariable logistic regression. Sources of living kidney transplants differed with deprivation (p Recipients living in poorer areas were more likely to receive a kidney from a sibling, child, and "other relative" donor and less likely from spouses/partners. Logistic regression suggested differences seen with spouse/partner donations with deprivation were explained by differences in the age and gender of the recipients. The source of living kidneys differs by level of area deprivation. Given the disparity in rates of living kidney transplants between the most and least socioeconomically deprived, there is a need to understand the reasons behind these observed relationship differences, with the aim of increasing transplantation rates in the most deprived. © 2013 John Wiley & Sons A/S.

  17. Organ donation and transplantation statistics in Belgium for 2012 and 2013. (United States)

    Desschans, B; Evrard, P


    The 2012 and 2013 solid organ transplantation statistics were presented during the annual meeting of the Belgian Transplant Society. All data presented were collected from Eurotransplant International Foundation and/or from all individual Belgian transplant centers. It was demonstrated that the highest number of deceased donors detected (1310) from which 47.8% were an effective organ donor that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Out of 626 effective deceased organ donors, 491 (79%) were donors after brain death (DBD) and 135 (21%) donors after circulatory death (DCD), respectively. The majority (125/135; 93%) of DCD donors were DCD Maastricht category III donors and there were 7 (5%) donations following euthanasia. Family refusal tended to be lower for DCD (10.4%) compared to DBD donors (13.4%). Despite the increasing DCD donation rate, DBD donation remains stable in Belgium. The donor age is still increasing, reaching a median age of 53 years (range 0-90). Spontaneous intracranial bleeding (39.3%) and cranio-cerebral trauma (25%) remained the most frequent reasons of death. The number of living related kidney transplantations (57 in 2012 and 63 in 2013) followed the international trend albeit in Belgium it is still very limited. Nevertheless this activity could explain that the number of patients waiting for kidney transplantation (770) reached an absolute minimum in 2013. Except the reduced waiting list for lung transplantation (from 119 patients in 2011 to 85 in 2013), the waiting list remained stable for the other organs but almost 200 patients still died while on the waiting list. Belgium demonstrated the highest number of effective organ donors that corresponded to 29 per million inhabitants (pmi) in 2012 and 27.4 pmi in 2013. Thus far, and in contrast with other countries, there is no erosion of DBD in the DCD donor organ pool, but it is the important responsibility of all transplant centers and donor hospitals to

  18. [Blood donation in urban areas]. (United States)

    Charpentier, F


    Medical and technical developments increase the difficulty to provide sufficient safe blood for all patients in developed countries and their sociodemographic and societal changes. Sufficient national blood supply remains a reached, however still actual, challenge. Tomorrow is prepared today: the management of blood donation programs both in line with these developments and with social marketing strategies is one of the keys to success. If the main components of this organization are well known (mobile blood drives in various appropriate environments, and permanent blood donation centers) their proportions in the whole process must evolve and their contents require adaptations, especially for whole blood donation in urban areas. We have to focus on the people's way of life changes related to increasing urbanization of the society and prominent position taken by very large cities. This requires targeting several goals: to draw the attention of the potential blood-giving candidate, to get into position to collect him when he will decide it, to give meaning and recognition to his "sacrifice" (give time rather than donate blood) and to give him desire and opportunity to come back and donate one more time. In this strategy, permanent blood centers in urban areas have significant potential for whole blood collection, highlighted by the decrease of apheresis technology requirements. This potential requires profound changes in their location, conception and organization. The concept of Maison Du Don (MDD) reflects these changes. Copyright © 2013. Published by Elsevier SAS.

  1. Trends of Blood and Plasma Donations in Kazakhstan: 12-Years Retrospective Analysis. (United States)

    Igissinov, Nurbek; Kulmirzayeva, Dariyana; Magzumova, Raushan; Sibinga, Cees Th Smit; Alpeissova, Sholpan


    Each country faces a continuing challenge to collect enough blood to meet the national needs. According to WHO, there should be at least 20 blood donations per 1,000 population for developing countries, in Kazakhstan this indicator was only 16.8 in 2011. Thus, we conducted an epidemiological assessment and drew a map of the regional distribution of blood and plasma donations in Kazakhstan during the years 2000-2011. The retrospective study was conducted from 2000 to 2011. Data on blood and its components donations were acquired from the Ministry of Health (annual statistical reporting form N° 39). During 2000-2011, number of blood donors decreased to 17.4% and blood donations to 6.3%. The proportion of non-remunerated blood donations and donors decreased from 97.6% to 77.9% and 97.9% to 87.7%, respectively. The paid donations had the opposite trend. Number of plasma donors increased in 2.1 times, plasma donations in 2.4 times, nevertheless the proportion of non-remunerated plasma donations decreased from 60.1% to 29.8%. The average number of blood donations per 1,000 population decreased from 19.8 (2000) to 16.8 (2011), plasma donations increased from 1.4 to 3.1. Regionally, annual average rates of blood and plasma donations per 1,000 population over 12 years varied greatly. This is the first study conducted in Kazakhstan to provide detailed information, including the regional characteristics of blood and plasma donations over an extended period of time, which can be used in blood transfusion services work.

  2. Bereaved donor families' experiences of organ and tissue donation, and perceived influences on their decision making. (United States)

    Sque, Magi; Walker, Wendy; Long-Sutehall, Tracy; Morgan, Myfanwy; Randhawa, Gurch; Rodney, Amanda


    To elicit bereaved families' experiences of organ and tissue donation. A specific objective was to determine families' perceptions of how their experiences influenced donation decision-making. Retrospective, qualitative interviews were undertaken with 43 participants of 31 donor families to generate rich, informative data. Participant recruitment was via 10 National Health Service Trusts, representative of five regional organ donation services in the UK. Twelve families agreed to DBD, 18 agreed to DCD, 1 unknown. Participants' responses were contextualised using a temporal framework of 'The Past', which represented families' prior knowledge, experience, attitudes, beliefs, and intentions toward organ donation; 'The Present', which incorporated the moment in time when families experienced the potential for donation; and 'The Future', which corresponded to expectations and outcomes arising from the donation decision. Temporally interwoven experiences appeared to influence families' decisions to donate the organs of their deceased relative for transplantation. The influence of temporality on donation-decision making is worthy of consideration in the planning of future education, policy, practice, and research for improved rates of family consent to donation.

  3. Relationships between Islamic religiosity and attitude toward deceased organ donation among American Muslims: a pilot study. (United States)

    Padela, Aasim I; Zaganjor, Hatidza


    Religion-rooted beliefs and values are often cited as barriers to organ donation among Muslims. Yet how Islamic religiosity relates to organ donation attitude among Muslims is less studied. Using a community based participatory research approach, we recruited adults from mosque communities to self-administer a questionnaire assessing levels of Islamic religiosity, attitude toward deceased organ donation, and sociodemographic descriptors. Of the 97 respondents, there were nearly equal numbers of men and women. Over a third were Arab American (n=36), and nearly a quarter were either South Asian (n=23) or African American (n=25). Respondents viewing difficulties in life as punishment from God had a decreased odds of believing deceased organ donation to be justified (OR 0.85, PArab Muslims were more likely to believe deceased organ donation to be justified than South Asian or African Americans (OR 7.06, PAmerican health-care system, were not significantly associated with attitude toward deceased organ donation. Higher levels of intrinsic religiosity or adherence to Islamic ethics do not appear to associate with negative attitudes toward deceased organ donation. Negative religious coping appears, however, to be related to lower rates of believing deceased organ donation to be justified. Future studies with larger samples that incorporate additional measures of religiosity can further clarify relationships between religiosity and organ donation attitude among Muslim communities.

  4. The rate of urinary tract abnormalities and the functional state of kidneys in relation to the degree of connective tissue dysplasia in children

    T. A. Kryganova


    Full Text Available The paper is devoted to the study of the rate of urinary tract abnormalities and kidney functions in children with mild, moderate, and severe connective tissue dysplasia. Severe connective tissue dysplasia was found to prevail in children with urinary tract abnormalities and to be characterized by a variety of urodynamic urinary tract abnormalities. Urinary system infection occurred equally frequently in both patient groups and its rate did not depend on the degree of the dysplasia. Some children with severe connective dysplasia were noted to have diminished renal filtration function. High-grade vesicoureteral reflux, tubular disorders as nocturias, and lowered urine osmolarity were more common in children with severe dysplasia. Hypertension was seen equally often in both patient groups, no matter what the degree of connective tissue dysplasia.

  5. Sociocultural perspective on organ and tissue donation among reservation-dwelling American Indian adults. (United States)

    Fahrenwald, Nancy L; Stabnow, Wendy


    To discover the sociocultural patterns that influence decisions about organ and tissue donation among American Indian (AI) adults. This qualitative ethnographic study used a social-ecological framework. A snowball sampling technique was used to recruit 21 Oglala Lakota Sioux participants (age >or= 19 years) living on the Pine Ridge Indian Reservation in South Dakota, USA. Face-to-face interviews were conducted using open-ended questions derived from the social-ecological perspective of Stokols (1992). Interviews were audiotaped and transcribed. Data were categorized into construct codes to identify concepts and to discover emerging themes. Personal and environmental themes regarding organ and tissue donation emerged. There were two personal themes: uncertain knowledge and the diabetes crisis. Participants knew very little about organ and tissue donation but there was a basic understanding of donor/recipient compatibility. The prevalence of diabetes in the community is contributing to a dire need for kidney donors. The diabetes crisis was acknowledged by every participant. There were three environmental themes: cultural transitions, healthcare system competence and outreach efforts. Traditional cultural beliefs such as entering the spirit world with an intact body were acknowledged. However, conversations reflected re-examination of traditional beliefs because of the need for kidney donors. The healthcare environmental context of organ and tissue donation emerged as a theme. Participants were not confident that the local health system was prepared to either address traditional beliefs about organ and tissue donation or implement a donation protocol. The final theme was the environmental context of outreach efforts. Participants desired relevant outreach targeted to the community and disseminated through local communication networks including the family, the media and tribal leaders. Sociocultural factors relevant to the personal and environmental context of the

  7. Cadaveric organ donation in China (United States)

    Wu, Yijin; Elliott, Robert; Li, Linzi; Yang, Tongwei; Bai, Yusen; Ma, Wen


    Abstract In this paper, we will discuss several ethical issues concerning cadaveric organ donation from the perspective of sociocultural factors that are unique to China under the condition that China has ended the use of executed prisoner's organs for transplants. It is found that though great developments have been made in organ transplantation, the ethical issues relating to organ transplantation still face dilemmas in China. It is argued that organ donation and transplantation in China could make further progress if the ethical issues proposed in this paper can be carefully considered. PMID:29517702

  8. Attitude of Healthcare Professionals: A Major Limiting Factor in Organ Donation from Brain-Dead Donors

    Directory of Open Access Journals (Sweden)

    Maciej Kosieradzki


    Full Text Available Public attitude toward deceased donor organ recovery in Poland is quite positive, with only 15% opposing to donation of their own organs, yet actual donation rate is only 16/pmp. Moreover, donation rate varies greatly (from 5 to 28 pmp in different regions of the country. To identify the barriers of organ donation, we surveyed 587 physicians involved in brain death diagnosis from regions with low (LDR and high donation rates (HDR. Physicians from LDR were twice more reluctant to start diagnostic procedure when clinical signs of brain death were present (14% versus 5.5% physicians from HDR who would not diagnose death, resp.. Twenty-five percent of LDR physicians (as opposed to 12% of physicians from HDR would either continue with intensive therapy or confirm brain death and limit to the so-called minimal therapy. Only 32% of LDR physicians would proceed with brain death diagnosis regardless of organ donation, compared to 67% in HDR. When donation was not an option, mechanical ventilation would be continued more often in LDR regions (43% versus 26.7%; P<0.01. In conclusion, low donation activity seems to be mostly due to medical staff attitude.

  11. Applicability of the Schwartz Equation and the Chronic Kidney Disease in Children Bedside Equation for Estimating Glomerular Filtration Rate in Overweight Children. (United States)

    Lewis, Teresa V; Harrison, Donald L; Gildon, Brooke L; Carter, Sandra M; Turman, Martin A


    To determine if significant correlations exist between glomerular filtration rate (GFR) prediction equation values, derived by using the original Schwartz equation and the Chronic Kidney Disease in Children (CKiD) bedside equation with a 24-hour urine creatinine clearance (Clcr ) value normalized to a body surface area of 1.73 m(2) in overweight and obese children. Prospective analysis (20 patients) and retrospective analysis (43 patients). Pediatric inpatient ward and pediatric nephrology clinic at a comprehensive academic medical center. Sixty-three pediatric patients (aged 5-17 years), of whom 27 were overweight (body mass index [BMI] at the 85th percentile or higher) and 36 were not overweight (BMI lower than the 85th percentile [controls]) between 2007 and 2012. Data from the overweight patients were compared with nonoverweight controls. GFR values were calculated by using the original Schwartz equation and the CKiD bedside equation. Each patient's 24-hour urine Clcr value normalized to a body surface area of 1.73 m(2) served as the index value. A Pearson correlation coefficient model was used to determine association between the 24-hour urine Clcr value (index value) with the Schwartz and CKiD GFR estimations. Significant correlation was found to exist between the Schwartz and CKiD bedside GFR estimations relative to the 24-hour urine Clcr in the control subjects (r = 0.85, poverweight subjects (r = 0.86, poverweight children with a kidney disorder. The CKiD bedside GFR estimations were not significantly different compared with 24-hour urine Clcr values for the overweight group with kidney disorder (p=0.85). The Schwartz and CKiD bedside estimations of GFR correlated with 24-hour urine Clcr values in both overweight and nonoverweight children. Compared with the Schwartz equation, which tended to overestimate renal function, the CKiD bedside equation appeared to approximate 24-hour urine Clcr more closely in overweight children with kidney disorder. © 2016

  13. Motivators and Barriers to Blood Donation in African American College Students (United States)

    Shaz, Beth H.; Demmons, Derrick G.; Crittenden, Colleen P.; Carnevale, Claudine V.; Lee, Mark; Burnett, Miriam; Easley, Kirk; Hillyer, Christopher D.


    Background An adequate blood supply depends on volunteer non-remunerated blood donors. African Americans have lower blood donation rates than whites. To improve African American blood donation rates, the motivators and barriers to African Americans must be explored. To study the differences in motivators and barriers to blood donation between donor and non-donor African American college students. Methods African Americans college students at two Historically Black Colleges and Universities completed a 41-item, self-administered questionnaire, which assessed participant’s donation frequency, motivators and barriers toward donation, and knowledge and beliefs towards blood donation. Results 364 primarily female college students (96% African Americans, 93% female) completed the questionnaire. 49% reported prior blood donation experience (donors) and 51% were non-donors. The primary motivator for donors and non-donors was convenience (89% donor, 82% non-donor). Donors were more likely than non-donors to disagree with statements regarding blood donation as being too painful (82% donor, 44% non-donor), resulting in feeling faint, dizzy, or nauseated (61% donor, 29% non-donor). Donors more often agreed that the blood supply is safe (77% donor, 58% non-donor), less often concerned about receiving a transfusion (61% donor, 73% non-donor), and more often aware of local blood shortages (50% donor, 35% non-donor). Conclusions African Americans female college students are willing to donate blood given convenience and support from their university. Educational campaigns to increase knowledge regarding the safety of the blood donation process and the ongoing needs of an adequate blood supply might be effective methods to increase blood donation.

  18. Assessing glomerular filtration rate (GFR) in critically ill patients with acute kidney injury - true GFR versus urinary creatinine clearance and estimating equations (United States)


    Introduction Estimation of kidney function in critically ill patients with acute kidney injury (AKI), is important for appropriate dosing of drugs and adjustment of therapeutic strategies, but challenging due to fluctuations in kidney function, creatinine metabolism and fluid balance. Data on the agreement between estimating and gold standard methods to assess glomerular filtration rate (GFR) in early AKI are lacking. We evaluated the agreement of urinary creatinine clearance (CrCl) and three commonly used estimating equations, the Cockcroft Gault (CG), the Modification of Diet in Renal Disease (MDRD) and the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations, in comparison to GFR measured by the infusion clearance of chromium-ethylenediaminetetraacetic acid (51Cr-EDTA), in critically ill patients with early AKI after complicated cardiac surgery. Methods Thirty patients with early AKI were studied in the intensive care unit, 2 to 12 days after complicated cardiac surgery. The infusion clearance for 51Cr-EDTA obtained as a measure of GFR (GFR51Cr-EDTA) was calculated from the formula: GFR (mL/min/1.73m2) = (51Cr-EDTA infusion rate × 1.73)/(arterial 51Cr-EDTA × body surface area) and compared with the urinary CrCl and the estimated GFR (eGFR) from the three estimating equations. Urine was collected in two 30-minute periods to measure urine flow and urine creatinine. Urinary CrCl was calculated from the formula: CrCl (mL/min/1.73m2) = (urine volume × urine creatinine × 1.73)/(serum creatinine × 30 min × body surface area). Results The within-group error was lower for GFR51Cr-EDTA than the urinary CrCl method, 7.2% versus 55.0%. The between-method bias was 2.6, 11.6, 11.1 and 7.39 ml/min for eGFRCrCl, eGFRMDRD, eGFRCKD-EPI and eGFRCG, respectively, when compared to GFR51Cr-EDTA. The error was 103%, 68.7%, 67.7% and 68.0% for eGFRCrCl, eGFRMDRD, eGFRCKD-EPI and eGFRCG, respectively, when compared to GFR51Cr-EDTA. Conclusions The study

  19. The debate in Chile on organ donation revisited. (United States)

    Kottow Lang, Miguel Hugo


    The worldwide scarcity of cadaveric organs for transplants is on the rise, due in part to extended medical indications and longevity of chronic patients with organic insufficiencies. Chile has an extremely low donor rate of 6.7 per million. Although consent is presumed by law, and recently amended to include a “reciprocity principle”, nearly four million persons have expressed in writing their unwillingness to donate and, of those remaining, 53% of families have rejected donating the organs of their deceased. New proposals are urgently needed, even if some of them have previously been rejected: nonmaterial incentives, partial donations and unveiling anonymity to enhance personal ties between donors and recipients. Transparency, information and assistance are to be reinforced in order to regain trust in transplant procedures.

  20. Family communication coordination: a program to increase organ donation. (United States)

    Linyear, A S; Tartaglia, A


    To improve organ donation performance, the Medical College of Virginia Hospitals implemented a comprehensive family support and communication program, consisting of a standard family communications protocol, a hospital-based team from the Department of Pastoral Care, targeted staff education, and an ongoing quality assurance measuring and monitoring system. The 3 best-demonstrated request practices, private setting, "decoupling," and collaboration in the request between the organ procurement organization and hospital staff, were incorporated into the program. Improvement in the consent and donation rate was evident in the second calendar year of the program; the consent rate was 72% and the donation rate was 50%. During the second year, there was also a positive correlation between "decoupling," appropriate requestor, and the consent rate. Implementation of a hospital-based team and a standard protocol facilitated the clarification of roles and responsibilities toward clearer and more consistent family communication and support. Data suggest that staff experience is a major contributor to a positive donation outcome.

    Low-frequency electrical stimulation has resulted in favorable effects in the treatment of post-stroke dysphagia. However, the safety of cervical low-frequency electrical stimulation remains unclear because of numerous nerves and blood vessels in the neck. In the present study, rats with ischemic stroke underwent low-frequency electrical stimulation, and systemic and local effects of electrical stimulation at different densities and waveforms were investigated. Electrical stimulation resulted in no significant effects on body mass, liver or kidney function, or mortality rate. In addition, no significant adverse reaction was observed, despite overly high intensity of low-frequency electrical stimulation, which induced laryngismus, results from the present study suggested that it is safe to stimulate the neck with a low-frequency electricity under certain intensities.

    The Modification of Diet in Renal Disease (MDRD) equation is recommended by most scientific societies to calculate the estimated glomerular filtration rate (GFR). Recently the group Chronic Kidney Disease Epidemiology Collaboration (CKP-EPI) has published a new, more precise and accurate equation. We have analyzed its behavior in a group of polypathological patients (PP) and compared it with the classic MDRD-4.version Multicenter, observational, descriptive and transversal study. We calculated GFR by MDRD-4 and CKD-EPI in 425 PP. Each stage was assigned according to the GFR: 1:>90; 2: 60-89; 3: 30-59; 4: 15-29; and 5 renal insufficiency, especially in older women.

  5. Re: Does Pre-emptive Transplantation versus Post Start of Dialysis Transplantation with a Kidney from a Living Donor Improve Outcomes After Transplantation? A Systematic Literature Review and Position Statement by the Descartes Working Group and ERBP

    Directory of Open Access Journals (Sweden)

    Yarkın Kamil Yakupoğlu


    Full Text Available EDITORIAL COMMENT In case of end stage kidney disease, living donation by expanding the donor pool might give a chance for pre-emptive kidney transplantation, which is defined as having a kidney transplant before initiation of chronic dialysis. In this guideline, Descartes Working Group conducted a systematic review of the literature which included observational data of 29 studies, mainly coming from single center or regional registries, performed after 1990 providing data on aspects of pre-emptive living donation. They found that around half of studies showed improvements in patient and graft survival or reductions in the risk of acute rejection. However, relating to pre-transplant glomerular filtration rate no differences were found between the graft and patient survivals. In the light of the data, the group recommends pre-emptive transplantation where possible, with the timing designed to avoid dialysis in patients who have kidney disease that is indefinitely irreversible and clearly progressive. There is also a selection bias. The characteristics of population who receive a pre-emptive kidney transplantation is very different from those receiving a transplant on the waiting list in the mentioned studies, which is well recognized by the authors.

  6. Modulation of cardiac autonomic tone in non-hypotensive hypovolemia during blood donation. (United States)

    Yadav, Kavita; Singh, Akanksha; Jaryal, Ashok Kumar; Coshic, Poonam; Chatterjee, Kabita; Deepak, K K


    Non-hypotensive hypovolemia, observed during mild haemorrhage or blood donation leads to reflex readjustment of the cardiac autonomic tone. In the present study, the cardiac autonomic tone was quantified using heart rate and blood pressure variability during and after non-hypotensive hypovolemia of blood donation. 86 voluntary healthy male blood donors were recruited for the study (age 35 ± 9 years; weight 78 ± 12 kg; height 174 ± 6 cms). Continuous lead II ECG and beat-to-beat blood pressure was recorded before, during and after blood donation followed by offline time and frequency domain analysis of HRV and BPV. The overall heart rate variability (SDNN and total power) did not change during or after blood donation. However, there was a decrease in indices that represent the parasympathetic component (pNN50 %, SDSD and HF) while an increase was observed in sympathetic component (LF) along with an increase in sympathovagal balance (LF:HF ratio) during blood donation. These changes were sustained for the period immediately following blood donation. No fall of blood pressure was observed during the period of study. The blood pressure variability showed an increase in the SDNN, CoV and RMSSD time domain measures in the post donation period. These results suggest that mild hypovolemia produced by blood donation is non-hypotensive but is associated with significant changes in the autonomic tone. The increased blood pressure variability and heart rate changes that are seen only in the later part of donation period could be because of the progressive hypovolemia associated parasympathetic withdrawal and sympathetic activation that manifest during the course of blood donation.

  7. Continuous Real-time Viability Assessment of Kidneys Based on Oxygen Consumption (United States)

    Background Current ex vivo quality assessment of donor kidneys is limited to vascular resistance measurements and histological analysis. New techniques for the assessment of organ quality before transplantation may further improve clinical outcomes while expanding the depleted deceased-donor pool. We propose the measurement of whole organ oxygen consumption rate (WOOCR) as a method to assess the quality of kidneys in real time before transplantation. Methods Five porcine kidneys were procured using a donation after cardiac death (DCD) model. The renal artery and renal vein were cannulated and the kidney connected to a custom-made hypothermic machine perfusion (HMP) system equipped with an inline oxygenator and fiber-optic oxygen sensors. Kidneys were perfused at 8°C, and the perfusion parameters and partial oxygen pressures (pO2) were measured to calculate WOOCR. Results Without an inline oxygenator, the pO2 of the perfusion solution at the arterial inlet and venous outlet diminished to near 0 within minutes. However, once adequate oxygenation was provided, a significant pO2 difference was observed and used to calculate the WOOCR. The WOOCR was consistently measured from presumably healthy kidneys, and results suggest that it can be used to differentiate between healthy and purposely damaged organs. Conclusions Custom-made HMP systems equipped with an oxygenator and inline oxygen sensors can be applied for WOOCR measurements. We suggest that WOOCR is a promising approach for the real-time quality assessment of kidneys and other organs during preservation before transplantation. PMID:20692397

  9. Gender Disparity in Kidney Transplantation

    Naghibi Orode


    Full Text Available Gender discrimination in benefiting from medical treatment is a worldwide pro-blem. Kidney transplantation, as the ideal treatment for patients with end-stage renal disease (ESRD, is not an exception. Considering the unique kidney donation patterns and different family styles in the Middle East, studying this problem in Iran seemed justifiable and necessary. In addition to comparing the numbers of female and male recipients, which has been done in other similar studies, considering the critical effect of waiting time on the outcome, we assessed and compared the waiting times also. The data of age, gender, nationality, donor type and waiting time before transplantation of 1426 (61.85% male, 38.14% female recipients who underwent transplantation in Imam Reza Hospital in the northeast of Iran from 1990 to 2003, was analyzed. Recipients were categorised into three groups based on donation patterns: those receiving kidney from live unrelated, live related and cadaver donors. The number of patients in each group was 1057 (61.96% male, 38.03% female, 232 (67.24% male, 32.75% female and 137 (51.82% male, 48.17% female respectively. The mean overall waiting time was 708 days. Comparing waiting time of male and female recipients in each of these groups did not show significant difference. In all categories of donors, females were less likely than males to be recipients. Furthermore, waiting time for females was longer than males when receiving kidney from sisters and children. For spousal donations, males were recipients more frequently than females although female recipients in this group waited less than their male counterparts to receive the kidney. Generally, our results are in accordance with results of similar researches. In all three mentioned groups, males com-prised the majority while the waiting time does not show significant difference between genders. We suggest some reasons for this phenomenon, of which the two main ones are: fewer females

  10. Accuracy of GFR estimation formula in determination of glomerular filtration rate in kidney donors: Comparison with 24 h urine creatinine clearance

    Directory of Open Access Journals (Sweden)

    Abdul Rauf Hafeez


    Full Text Available To determine the accuracy of estimated glomerular filtration rate (eGFR using the modification of diet in renal disease (MDRD, Cockcroft-Gault (CG, and chronic kidney disease epidemiology (CKD-EPI formulas in potential kidney donors compared with 24-h urine creatinine clearance, we studied 207 potential live kidney donors in our center. There were 126 (60.9% males and 81 (39.1% females. Male:female ratio was 1.6:1. The age of the donors ranged from 18-58 years, with mean age of 35.30 ± 9.23 years and most of the individuals were below 40 years of age. The body mass index (BMI was calculated and venous blood samples were obtained for the measurement of serum creatinine and every study participant was instructed to collect 24-h urine. GFR was calculated based on 24-h urine creatinine clearance and the formulas. The accuracy of GFR estimation formula was taken as positive if the GFR calculated by the formulas and urine creatinine clearance fell between 90-120 mL/min/1.73 m 2 . The accuracy of the MDRD formula was 48.8% and the CG formula was 41.5% whereas the accuracy of the CKD-EPI formula was 78.2%. The accuracy of the eGFR using the MDRD formula was significantly higher in males than females (57.9% vs. 33.3% P = 0.001, while there was no statistically significant difference in the eGFR between them in case of the use of the CG and the CKD-EPI formulas. BMI and obesity had no effect on the accuracy of eGFR by the use of the different formulas. The performance of GFR estimation formulas was sub optimal and these either underestimated and/or over-estimated the GFR in healthy subjects. CKD-EPI is closer to 24 -h urinary creatinine clearance in the calculation of eGFR. However, none of the eGFR formulas can be used in renal transplant donors because of their low accuracy, and 24-h urine creatinine clearance should be used for evaluation of the GFR in this population.

  11. Are lapsed donors willing to resume blood donation, and what determines their motivation to do so? (United States)

    van Dongen, Anne; Abraham, Charles; Ruiter, Robert A C; Schaalma, Herman P; de Kort, Wim L A M; Dijkstra, J Anneke; Veldhuizen, Ingrid J T


    This study investigated the possibility of rerecruiting lapsed blood donors. Reasons for donation cessation, motivation to restart donation, and modifiable components of donation motivation were examined. We distinguished between lapsed donors who had passively withdrawn by merely not responding to donation invitations and donors who had contacted the blood bank to actively withdraw. A cross-sectional survey was sent to 400 actively lapsed donors and to 400 passively lapsed donors, measuring intention to restart donation and psychological correlates of restart intention. The data were analyzed using multiple regression analyses. The response rate among actively lapsed donors was higher than among passively lapsed donors (37% vs. 25%). Actively lapsed donors typically ceased donating because of physical reactions, while passively lapsed donors quit because of a busy lifestyle. Nonetheless, 51% of actively lapsed responders and 80% of passively lapsed responders were willing to restart donations. Multiple regression analysis showed that, for passively lapsed donors, cognitive attitude was the strongest correlate of intention to donate in the future (β=0.605, pattitude (β=0.239, pattitude was also the strongest correlate of intention (β=0.601, pattitude (β=0.345, pattitudes and self-efficacy could further raise such intentions. © 2011 American Association of Blood Banks.

  12. [Attitude towards organ and tissue donation in Europe : Prerequisite for osteochondral allograft treatment]. (United States)

    Schmidt, S; Schulte, A; Schwarz, S; Hofmann, N; Tietz, S; Boergel, M; Sixt, S U


    The biggest obstacle to overcome for routine treatment of various pathologies with fresh osteochondral allograft is the availability of tissue for transplantation. Large fresh osteochondral allografts are usually harvested from organ donors, but in contrast to organs, tissues can be procured after cardiac arrest. Medical staff as well the general public are much less aware of the possibilities and requirements of tissue donation compared to organ donation. This review aims to highlight the current situation of organ and tissue donation in Europe and to raise this much needed awareness. For this research, PubMed database was scanned using the terms "tissue/organ donation", "bone donation/transplantation", "cartilage transplantation/allografts" and "osteochrondral allografts". Relatives of potential donors are often not approached because physicians and nurses do not feel sufficiently prepared for this task and, thus, are reluctant to address this topic. Different options could alleviate the pressure medical staff is feeling. Furthermore, there are different factors influencing consent that can be addressed to increase donation rates. Currently, a lot of potential concerning musculoskeletal tissue grafts remains unused. Most importantly, families should be encouraged to speak about their potenzial will to donate and educational programs should be established to increase trust in organ and tissue donation and the allocation system and to increase knowledge about the importance of transplantation medicine. But joined efforts of different parts of the medical systems and different organizations involved in tissue transplantation should improve the situation for patients waiting for much needed transplants.

  13. Factors associated with positive attitudes toward organ donation in Arab Americans. (United States)

    Padela, Aasim I; Rasheed, Shoaib; Warren, Gareth J W; Choi, Hwajung; Mathur, Amit K


    The demand for transplantable organ continues to exceed supply, particularly in minority patient populations. We explored the factors influencing organ donation attitude within the Arab American community. Secondary data analysis from a face-to-face survey administered in late 2003 to 1016 adults from a representative population-based sample on Greater Detroit Arab Americans. Christian Arab Americans were more likely than Muslim Arab Americans, and women more than men, to believe organ donation after death was justifiable. Higher educational attainment and income, as well as greater acculturation into American society, were associated with greater odds of believing organ donation to be justified. Self-reported health status and level of psychological distress and health insurance status were not associated with beliefs about organ donation. A multifaceted approach toward increasing organ donation rates in this growing population requires targeted community-health care system collaborations involving religious and civic leaders using Arabic language and culturally sensitive media. Arab Americans represent a growing population about which little is known in regard to organ donation and transplantation. This population is not specifically captured within national and local transplantation databases, and little empiric work has assessed attitudes and barriers toward organ donation and transplantation within this community. Our work represents the first to use a representative population-based sample to explore the modifiable and non-modifiable characteristics of those who believe cadaveric organ donation to be justified. © 2010 John Wiley & Sons A/S.

  16. A Comparative Study of Organ Donation after Brain Death in Japan and Australia


    TERAO, Kaori; FUJIWARA, Yoshirou


    Objective : (1) To compare the status of organ donation from brain-dead donors in Japan and Australia. (2) To identify the possible reasons for the low rates of organ donation from brain-dead donors. Background : The shortage of available organs for transplantation has prompted many countries to develop a system for the use of organs from brain-dead donors, including Japan and Australia. Yet, there is a wide range of organ donation rates and policies between Japan and Australia in the current...

  17. Determination of the knowledge level, attitudes, and behaviors of islamic religious officials toward blood donation. (United States)

    Keten, Hamit Sirri; Isik, Oguz; Kus, Celal; Ersoy, Ozgur; Olmez, Soner; Yildirim, Fatis; Celik, Mustafa


    The aim of the present study was to determine knowledge level, attitudes, and behaviors of Islamic religious officials toward blood donation. This study included 334 religious officials rendering service in the province of Kahramanmaras, located in the Mediterranean region of Turkey. A questionnaire was administered to gather sociodemographic data of the participants and their knowledge levels, attitudes, and behaviors toward blood donation. The questionnaire consisted of 11 questions that yielded a total of 11 points. The religious officials in the study included 206 imams (61.7%, males) and 128 Quran course instructors (38.3%, females). Of study participants, 134 (40.1%) reported a previous experience of blood donation and 200 (59.9%) denied previous experience of blood donation. The mean knowledge score was 7.09±2.54 points for males and 6.89±2.18 points for females. Male and female participants achieved comparable scores (p=0.476). Of the participants, 291 (87.1%) agreed and nine (2.7%) disagreed with the expression, "Blood donation is permissible in Islam;" 34 (10.2%) participants had no idea. The present study revealed considerable deficiencies in knowledge about blood donation among religious officials. In addition, the rate of blood donation and willingness to donate blood were low among religious officials. Although the level of knowledge about blood donation was similar in males and females, it was an interesting finding that the blood donation rate was significantly higher in males than in females.

  18. The modified CKD-EPI equation may be not more accurate than CKD-EPI equation in determining glomerular filtration rate in Chinese patients with chronic kidney disease. (United States)

    Xie, Peng; Huang, Jian-Min; Li, Ying; Liu, Huai-Jun; Qu, Yan


    To investigate the application of the new modified Chronic Kidney Disease Epidemiology Collaboration (mCKD-EPI) equation developed by Liu for the measurement of glomerular filtration rate (GFR) in Chinese patients with chronic kidney disease (CKD) and to evaluate whether this modified form is more accurate than the original one in clinical practice. GFR was determined simultaneously by 3 methods: (a) 99m Tc-diethylene triamine pentaacetic acid ( 99m Tc-DTPA) dual plasma sample clearance method (mGFR), which was used as the reference standard; (b) CKD-EPI equation (eGFRckdepi); (c) modified CKD-EPI equation (eGFRmodified). Concordance correlation and Passing-Bablok regression were used to compare the validity of eGFRckdepi and eGFRmodified. Bias, precision and accuracy were compared to identify which equation showed the better performance in determining GFR. A total of 170 patients were enrolled. Both eGFRckdepi and eGFRmodified correlated well with mGFR (concordance correlation coefficient 0.90 and 0.74, respectively) and the Passing-Bablok regression equation of eGFRckdepi and eGFRmodified against mGFR was mGFR = 0.37 + 1.04 eGFRckdepi and -49.25 + 1.74 eGFRmodified, respectively. In terms of bias, precision and 30 % accuracy, eGFRmodified showed a worse performance compared to eGFRckdepi, in the whole cohort. The new modified CKD-EPI equation cannot replace the original CKD-EPI equation in determining GFR in Chinese patients with CKD.

  19. Errors in Computing the Normalized Protein Catabolic Rate due to Use of Single-pool Urea Kinetic Modeling or to Omission of the Residual Kidney Urea Clearance. (United States)

    Daugirdas, John T


    The protein catabolic rate normalized to body size (PCRn) often is computed in dialysis units to obtain information about protein ingestion. However, errors can manifest when inappropriate modeling methods are used. We used a variable volume 2-pool urea kinetic model to examine the percent errors in PCRn due to use of a 1-pool urea kinetic model or after omission of residual urea clearance (Kru). When a single-pool model was used, 2 sources of errors were identified. The first, dependent on the ratio of dialyzer urea clearance to urea distribution volume (K/V), resulted in a 7% inflation of the PCRn when K/V was in the range of 6 mL/min per L. A second, larger error appeared when Kt/V values were below 1.0 and was related to underestimation of urea distribution volume (due to overestimation of effective clearance) by the single-pool model. A previously reported prediction equation for PCRn was valid, but data suggest that it should be modified using 2-pool eKt/V and V coefficients instead of single-pool values. A third source of error, this one unrelated to use of a single-pool model, namely omission of Kru, was shown to result in an underestimation of PCRn, such that each ml/minute Kru per 35 L of V caused a 5.6% underestimate in PCRn. Marked overestimation of PCRn can result due to inappropriate use of a single-pool urea kinetic model, particularly when Kt/V <1.0 (as in short daily dialysis), or after omission of residual native kidney clearance.

  20. Comparison of glomerular filtration rate measured by plasma sample technique, Cockroft Gault method and Gates’ method in voluntary kidney donors and renal transplant recipients

    International Nuclear Information System (INIS)

    Hephzibah, Julie; Shanthly, Nylla; Oommen, Regi


    There are numerous methods for calculation of glomerular filtration rate (GFR), which is a crucial measurement to identify patients with renal disease. The aim of this study is to compare four different methods of GFR calculation. Clinical setup, prospective study. Data was collected from routine renal scans done for voluntary kidney donors (VKD) or renal transplant recipients 6 months after transplantation. Following technetium-99m diethylene triamine penta acetic acid injection, venous blood samples were collected from contralateral arm at 120, 180, and 240 min through an indwelling venous cannula and direct collection by syringe. A total volume of 1 ml of plasma from each sample and standards were counted in an automatic gamma counter for 1 min. Blood samples taken at 120 min and 240 min were used for double plasma sample method (DPSM) and a sample taken at 180 min for single plasma sample method (SPSM). Russell's formulae for SPSM and DPSM were used for GFR estimation. Gates’ method GFR was calculated by vendor provided software. Correlation analysis was performed using Pearson's correlation test. SPSM correlated well with DPSM. GFR value in healthy potential kidney donors has a significant role in the selection of donors. The mean GFR ± (standard deviation) in VKD using SPSM, DPSM, camera depth method and Cockroft Gault method was 134.6 (25.9), 137.5 (42.4), 98.6 (15.9), 83.5 (21.1) respectively. Gates’ GFR calculation did not correlate well with plasma sampling method. Calculation of GFR plays a vital role in the management of renal patients, hence it was noted that Gates GFR may not be a reliable method of calculation. SPSM was more reliable. DPSM is reliable but cumbersome. It is difficult to accurately calculate GFR without a gold standard

  1. Enzymatic creatinine assays allow estimation of glomerular filtration rate in stages 1 and 2 chronic kidney disease using CKD-EPI equation. (United States)

    Kuster, Nils; Cristol, Jean-Paul; Cavalier, Etienne; Bargnoux, Anne-Sophie; Halimi, Jean-Michel; Froissart, Marc; Piéroni, Laurence; Delanaye, Pierre


    The National Kidney Disease Education Program group demonstrated that MDRD equation is sensitive to creatinine measurement error, particularly at higher glomerular filtration rates. Thus, MDRD-based eGFR above 60 mL/min/1.73 m² should not be reported numerically. However, little is known about the impact of analytical error on CKD-EPI-based estimates. This study aimed at assessing the impact of analytical characteristics (bias and imprecision) of 12 enzymatic and 4 compensated Jaffe previously characterized creatinine assays on MDRD and CKD-EPI eGFR. In a simulation study, the impact of analytical error was assessed on a hospital population of 24084 patients. Ability using each assay to correctly classify patients according to chronic kidney disease (CKD) stages was evaluated. For eGFR between 60 and 90 mL/min/1.73 m², both equations were sensitive to analytical error. Compensated Jaffe assays displayed high bias in this range and led to poorer sensitivity/specificity for classification according to CKD stages than enzymatic assays. As compared to MDRD equation, CKD-EPI equation decreases impact of analytical error in creatinine measurement above 90 mL/min/1.73 m². Compensated Jaffe creatinine assays lead to important errors in eGFR and should be avoided. Accurate enzymatic assays allow estimation of eGFR until 90 mL/min/1.73 m² with MDRD and 120 mL/min/1.73 m² with CKD-EPI equation. Copyright © 2013 Elsevier B.V. All rights reserved.

  3. The Risk of Transplant Failure With HLA Mismatch in First Adult Kidney Allografts 2: Living Donors, Summary, Guide


    Williams, Robert C.; Opelz, Gerhard; Weil, E. Jennifer; McGarvey, Chelsea J.; Chakkera, Harini A.


    Background Allografts from living donors survive longer than those from deceased donors but the role of HLA mismatching in living kidney donation is still in question. We examined the effect of HLA compatibility on kidney allograft survival from living donors by studying all first adult kidney transplants performed in the United States over 25 years. Methods Using the United Network for Organ Sharing data, we identified first kidney transplants between October 1, 1987, and December 31, 2013. ...

  4. Lipaemic donations: truth and consequences. (United States)

    Lippi, Giuseppe; Franchini, Massimo


    The problem of using material of unsuitable quality, including "nontransparent turbid milky plasma" or more simply "turbid plasma", for producing blood components is not trivial for several epidemiological, technical, analytical, clinical and economical reasons. With some exception, most national and international guidelines mandate that blood components should preferably not be produced from lipaemic donations. The origin of lipaemic blood is variegated, and includes physiological or paraphysiological causes and metabolic disorders, whereas a broad range of common diseases and drugs can also be associated with hypertriglyceridaemia. Overall, the frequency of lipaemic donations ranges between 0.31% and 0.35%, although sporadic reports have highlighted that the frequency might be much higher, up to 13%. Lipaemic donations pose two leading problems in transfusion medicine, that are interference during laboratory testing, and safety of producing blood components from hypertriglyceridaemic materials. While the former issue can be overcome by using chemical or mechanical methods, the clinical use of lipaemic blood for producing components remains an unresolved question. Transfusion medicine should thereby embark on a landmark effort to find a universal agreement of behaviours and harmonization of policies worldwide. Copyright © 2012 Elsevier Ltd.

    Chen, Jiang-hua; Lü, Rong; Chen, Ying; Wu, Jian-yong; He, Qiang; Huang, Hong-feng; Qu, Li-hui


    To investigate the influence of pre-transplant sCD30 level on the long-term survival rates of kidney transplant recipients and grafts among Chinese. A retrospective cohort of 707 patients undergoing cadaver renal transplants between Dec.1998 and Aug 2003, 467 males and 240 females, aged 40 +/- 11, with their blood samples preserved was studied. The plasma levels of sCD30 were determined by ELISA. The 5-year graft survival/functional rates of the high sCD30 group were 77.7% +/- 3.5%/85.0% +/- 3.2%, significantly lower than those of the low and intermediate groups, 84.7% +/- 2.1%/98.9% +/- 1.1% and 88.1% +/- 2.9%/95.1% +/- 1.6% respectively (all P sCD30 group was 92.4% +/- 1.6%, higher than those of the low and high sCD30 groups, 84.7% +/- 3.9% and 87.1% +/- 2.7% respectively with a significant difference between the intermediate and high sCD30 groups (P = 0.032). Pre-transplant serum level of sCD30 reflects the immune status. Recipients with high sCD30 are prone to rejection while those with low sCD30 are prone to infections.

  8. Effect of Contract Compliance Rate to a Fourth-Generation Telehealth Program on the Risk of Hospitalization in Patients With Chronic Kidney Disease: Retrospective Cohort Study. (United States)

    Hung, Chi-Sheng; Lee, Jenkuang; Chen, Ying-Hsien; Huang, Ching-Chang; Wu, Vin-Cent; Wu, Hui-Wen; Chuang, Pao-Yu; Ho, Yi-Lwun


    Chronic kidney disease (CKD) is prevalent in Taiwan and it is associated with high all-cause mortality. We have shown in a previous paper that a fourth-generation telehealth program is associated with lower all-cause mortality compared to usual care with a hazard ratio of 0.866 (95% CI 0.837-0.896). This study aimed to evaluate the effect of renal function status on hospitalization among patients receiving this program and to evaluate the relationship between contract compliance rate to the program and risk of hospitalization in patients with CKD. We retrospectively analyzed 715 patients receiving the telehealth care program. Contract compliance rate was defined as the percentage of days covered by the telehealth service before hospitalization. Patients were stratified into three groups according to renal function status: (1) normal renal function, (2) CKD, or (3) end-stage renal disease (ESRD) and on maintenance dialysis. The outcome measurements were first cardiovascular and all-cause hospitalizations. The association between contract compliance rate, renal function status, and hospitalization risk was analyzed with a Cox proportional hazards model with time-dependent covariates. The median follow-up duration was 694 days (IQR 338-1163). Contract compliance rate had a triphasic relationship with cardiovascular and all-cause hospitalizations. Patients with low or very high contract compliance rates were associated with a higher risk of hospitalization. Patients with CKD or ESRD were also associated with a higher risk of hospitalization. Moreover, we observed a significant interaction between the effects of renal function status and contract compliance rate on the risk of hospitalization: patients with ESRD, who were on dialysis, had an increased risk of hospitalization at a lower contract compliance rate, compared with patients with normal renal function or CKD. Our study showed that there was a triphasic relationship between contract compliance rate to the

  9. An Exploratory Study on University Students' Perceptions of Posthumous Organ Donation Base on the Theory of Reasoned Action. (United States)

    Wong, Shui Hung; Chow, Amy Yin Man


    In view of the general support for organ donation but low registration rate in Hong Kong, the present research attempted to understand the attitude-behavior inconsistency by identifying the underlying beliefs for organ donation through employing the theory of reasoned action. A qualitative approach using semi-structured focus groups was adopted and 19 students from three universities in Hong Kong participated; 10 constructs were identified: attitude, subjective norm, helping, continuation, contribution, body intact, distrust to the medical system, indifference to organ donation, negative affect, and family burden. Findings suggested that their attitudes toward organ donation were of both the cognitive and affective nature; subjective norm of family, friends, and people they respect were identified as influential to students' views on organ donation. The study provided insight in promoting organ donation, that the cognitive concerns about keeping the body intact, and the negative affects introduced should also be addressed.

  10. Ethical and Logistical Issues Raised by the Advanced Donation Program "Pay It Forward" Scheme. (United States)

    Ross, Lainie Friedman; Rodrigue, James R; Veatch, Robert M


    The advanced donation program was proposed in 2014 to allow an individual to donate a kidney in order to provide a voucher for a kidney in the future for a particular loved one. In this article, we explore the logistical and ethical issues that such a program raises. We argue that such a program is ethical in principle but there are many logistical issues that need to be addressed to ensure that the actual program is fair to both those who do and do not participate in this program. © The Author 2017.

  11. Strategies for changing negative public attitudes toward organ donation in the People’s Republic of China (United States)

    Shumin, Xie; Woo, Stephanie Mu-Lian; Lei, Zhang


    In recent decades, the demand for organ transplantation has risen rapidly worldwide, due to an increased incidence of vital organ failure. However, the scarcity of organs appropriate for transplantation has led to an organ shortage crisis. This article retrospectively reviews strategies to change negative public attitudes toward organ donation in the People’s Republic of China. We strongly believe that efforts to publicize knowledge of organ donation, promote family discussions, train medical staff and students, establish incentive systems, and implement regulatory oversight may combat unfavorable Chinese public opinion toward organ donation and transplantation, thus potentially increasing the organ donation rate in the People’s Republic of China.

  12. Drivers of Discretionary Firm Donations in Brazil

    Directory of Open Access Journals (Sweden)

    Rodrigo Bandeira-de-Mello


    Full Text Available Discretionary firm donation is usually related to the stakeholder theory and corporate social performance. Although theoretical explanations for this social behavior are pervasive in related literature, empirical modeling remains underdeveloped. We developed an explanatory structural model of discretionary firm donation using firm and industry level indicators. Unlike previous research, we estimated the explanatory power of the construct we called stakeholder orientation. Our tentative model was tested on a Brazilian sample of 101 publicly traded donor firms, using data on firm donations to social projects and to political candidates in electoral campaigns. The main results suggest that discretionary donation seems to be a strategy for managing conflicting claims in highly stakeholder oriented firms; the characteristics of the firm are more important than industry effects in explaining firm donations; and large firms, showing slack resources, and with a less concentrated ownership structure tend to engage in discretionary donation more intensively.

    Full Text Available CONTEXT : Organ transplantation is considered one of the greatest advances of modern science that has given many patients a renewed lease of life. Assessing the medical student’s knowledge, attitude and perception regarding organ donation is very importan t for future organ supply as they are the future doctors who needs to motivate the public to pledge their organs for donation. AIM & OBJECTIVES : 1 To study the knowledge and attitude of the medical students towards organ donation. 2 To understand the per ceptions of medical students regarding organ donation. STUDY DESIGN : A cross sectional study of descriptive nature. STUDY SETTING : Study was conducted at Andhra Medical College, Visakhapatnam. METHODS AND MATERIAL S : The study was done among 123 medical stu dents of 9 th semester using a semi - structured questionnaire. Knowledge was assessed by giving score to the responses. Those obtaining a score of 50% or above were considered as having adequate knowledge. STATISTICAL ANALYSIS : Data was entered in MS excel and analysed using SPSS student version 21 . RESULTS : Overall 56 % of students were found to have adequate knowledge. Around one fourth of the study population knew about the various organs which can be donated (26% and about t he minimum duration of organ survival (27.6%. Around 48.8% students showed positive attitude towards organ donation and wanted to donate their organs. CONCLUSION : It has been found in the study about the gaps in the knowledge levels of medical students ab out organ donation. These findings draw attention to a need to review medical school curricula to ensure that they contain sufficient teaching on organ donation, with a focus on information needed by physicians to maximize donation rates. This can be utili zed as a strategy for the shortage of donor organs for transplantation

  14. A Systematic Literature Review and Research Agenda for Organ Donation Decision Communication. (United States)

    Knox, Kathy; Parkinson, Joy; Pang, Bo; Fujihira, Haruka; David, Patricia; Rundle-Thiele, Sharyn


    This study systematically located and appraised peer-reviewed evidence for the efficacy of strategies to increase organ donation decision communication among adults including an assessment of study quality to guide future research in this field. There is little room to move in strengthening unanimously positive public attitudes toward organ donation. Consequently, researchers have called for a focus on organ donation decision communication to understand modifiable factors to increase organ donation rates. Multiple databases were searched during September 2015, and 44 studies were selected for inclusion. Data concerning participants, design, and outcomes were extracted. Studies were rated for quality and levels of evidence. Although not amenable to meta-analysis, the literature indicates that approximately 50% of adults who are willing to become an organ donor have discussed this decision with family. The majority of research was conducted in a Western context with an overrepresentation of students. Strategies to increase communication include education, motivation, input from lived experience, efforts to address salient audience beliefs, and scheduled reminders or prompts. Intentions and willingness to discuss organ donation were consistently positively related to discussion behavior; however, formative research and experimental studies testing theoretically driven interventions were scarce. There is mixed evidence for the role of demographic and attitudinal characteristics in the success of organ donation communication interventions. Additional theoretically based research is recommended to establish boundary conditions and validate strategies to increase organ donation decision communication among adults.

    WANG Wei; TIAN Hui; YIN Hang; LIU Hang; ZHANG Xiao-dong


    Background Organ transplantation represents an important advance in modern medical science,and it has benefited many patients with organ failure; however,the severe deficiency of organ sources has been a bottleneck that has limited the benefits -this technology can bring.The aim of this study was to show the results of a survey on Chinese people's awareness and attitudes toward organ donation.Methods We designed a questionnaire regarding organ donation consisting of 20 short questions,which were distributed to 10 groups.Most of the questions were multiple-choice; the core question related to people's attitudes to organ donation and the development of organ donation.The survey was held in the outpatient hall of Beijing Chao-Yang Hospital,a commercial district,and four professional colleges.Participants were randomly selected,and answered questions about gender,age,educational background,profession,and study major.Results In all,2930 valid responses were received.Male:female ratio was nearly 1:1.2 (mean age 38 years).Over 90.0% of participants knew about organ transplantation and which organs could be transplanted; more than 95.0% knew about organ donation,but the time they had been aware of it varied.Nearly 90.0% of the participants approved of deceased organ donation; 73.0% indicated they would like to donate their organs post mortem.Participants who knew more about organ failure and organ transplantation were more likely to support organ donation.College students were very positive about organ donation,though as they gain professional knowledge their attitudes may change.Altogether,65.3% of participants approved of living organ donation,which was obviously lower than the figure for deceased organ donation (P <0.05).In all,85.7% of participants approved of compensation to the deceased donor's family.To promote organ donation in China,62.9% of participants indicated that the public's knowledge about organ donation should be increased via the media

  2. Prospective audit to evaluate the potential of the coronial system to increase solid organ donation. (United States)

    Twamley, Huw; Haigh, Andrew; Williment, Claire; Hudson, Cara; Whitney, Julie; Neuberger, James


    Anecdotal evidence suggests that organ donation from deceased donors referred to the Coroner/Procurator Fiscal (PF) could be increased if all followed best practice. The aim of this prospective audit was to establish how referrals affected organ donation and to develop evidence-based guidelines to ensure that organ donation can be facilitated safely without interfering in the Coroner/PF's investigative process. Prospective audit. All acute National Health Service Hospitals in the UK where deceased organ donation was considered. 1437 deceased patients who met the eligibility criteria for organ donation and were referred to Coroner/PF. Number of cases where permission for transplantation was given, number of organs where permission was refused and number of organs which might have been transplanted if all had followed best practice. Full permission for organ retrieval was given in 87% cases and partial permission in 9%. However, if full permission had been given where no autopsy was performed or restrictions seemed unjustified, up to 77 organs (22 lungs, 22 kidneys, 9 pancreases, 9 livers, 8 hearts and 7 small bowels) could have been available for transplant. Coroners/PFs and their officers show strong support for transplantation but improvement in practice could result in a small but significant increase in life-saving and life-enhancing transplants.

  3. Knowledge, Attitude and Practice of Nurses Regarding Organ Donation (United States)

    Babaie, Mohadese; Hosseini, Mahdi; Hamissi, Jalaleddin; Hamissi, Zahra


    Introduction: Treatment team charged to help patients and their family making decision about donate organs in the final stage of life. Hence, their knowledge and attitude is important to plan of increasing the rate of organ donation. Materials and Methods: About 150 nurses recruited in this cross-sectional study randomly. After taking informed consent, questionnaires were filled. The data collection tool was a multipart questionnaire including demographic information, 18 questions about attitude and practice and 15 question about knowledge toward organ donation. Data were analyzed by SPSS software using K-squire, Pearson correlation test, T-test, variance analyze on 95% confidence interval. Results: Most of participants (76%) were 25-44 years old. About 81.3% of them were female (n=122). The attitude average score between males and females was 85.25±35.61 and 70.37±46.53, respectively. The practice average score in females was 34.43±47.71 and between males was 29.63±46.53. The knowledge average scores were 50.60±16.19 and 56.54±17.48 for two groups (p>0.05). The knowledge average scores between different age groups was significant (porgan donation, it seems that educational curriculum and facilities should applied to enhance attitude and behavior favorable change of personnel towards this issue.

  5. Should commercial organ donation be legalized in Germany? An ethical discourse. (United States)

    Keller, F; Winkler, U; Mayer, J; Stracke, S


    We evaluated the arguments pro and con concerning kidney sales from a German perspective. At present, we see social, medical, and ethical reasons why organ selling should not be legalized in Germany. Legalization of organ selling would weaken the principle of solidarity within the German health system. Conversely, profit making will undermine the principle of social justice. Within the present social system in Germany, there is no economic pressure to sell an organ to save life, and there is no medical need to buy a kidney. Also, there exists the risk that opening the market for organ sales will de-motivate potential directed organ donors. Relatives would have more doubts about giving their consent to donate organs of their deceased. Moreover, the historical experience with the "action T4" of the Nazi regime sensitized German society for the categorical imperative set forth by Immanuel Kant (1724-1804), namely that man is not a means, but an end to himself. By selling one's kidney, the donor uses himself as a means and as an instrument for the end result of gaining money. With directed organ donation, the welfare of the recipient is the end result. The pending reform of the German health system needs a more communitarian sense, which will be eroded should organs be sold and no longer donated as gifts. Germany's special historical experience and a deeply embedded consent toward ethical values give reason for the prohibition of organ selling in Germany.

  6. Association Between Contrast Media Volume-Glomerular Filtration Rate Ratio and Contrast-Induced Acute Kidney Injury After Primary Percutaneous Coronary Intervention. (United States)

    Celik, Omer; Ozturk, Derya; Akin, Fatih; Ayca, Burak; Yalcın, Ahmet Arif; Erturk, Mehmet; Bıyık, Ismail; Ayaz, Ahmet; Akturk, Ibrahim Faruk; Enhos, Asım; Aslan, Serkan


    We hypothesized that contrast media volume-estimated glomerular filtration rate (CV-e-GFR) ratio may be a predictor of contrast media-induced acute kidney injury (CI-AKI). We investigated the associations between CV-e-GFR ratio and CI-AKI in 597 patients undergoing primary percutaneous coronary intervention (pPCI). An absolute ≥0.3 mg/dL increase in serum creatinine compared with baseline levels within 48 hours after the procedure was considered as CI-AKI; 78 (13.1%) of the 597 patients experienced CI-AKI. The amount of contrast during procedure was higher in the CI-AKI group than in those without CI-AKI (153 vs 135 mL, P = .003). The CV-e-GFR ratio was significantly higher in patients with CI-AKI than without (2.3 vs 1.5, P 2 (P < .001, OR = 5.917). In conclusion, CV-e-GFR ratio is significantly associated with CI-AKI after pPCI. © The Author(s) 2014.

    Ramanathan Kumaresan


    Full Text Available  Objectives: There is no literature available on the performance of cystatin C in Chronic Kidney Disease (CKD patients of Indian population based on age group. Hence, this study is aimed to compare the diagnostic performance of serum cystatin C and creatinine with measured glomerular filtration rate (GFR and estimated GFR (eGFR in subjects of Indian origin. Methods: The study was carried out at Tiruchirappalli, South India during the period of September 2010 to march 2011. One hundred and six CKD patients (82 males, 24 females were enrolled and categorized into three groups based on age. The eGFR was calculated using Cockcroft-Gault (CG and Modification of Diet in Renal Disease (MDRD formulae. Serum cystatin C was measured with a particle-enhanced nephelometric immunoassay (PENIA method. GFR was measured using 99mTC - diethylene triamine penta aceticacid (DTPA renal scan method. Results: Serum cystatin C showed significant correlation with measured GFR in all the three groups (r=-0.9735, r=-0.8975 and r=-0.7994 respectively than serum creatinine (r=-0.7380, r=- 0.6852 and r=-0.5127 respectively. Conclusion: Serum cystatin C showed a high correlation with measured GFR in young and older patients with CKD than creatinine. Thus, cystatin C is a good alternative marker to creatinine in CKD patients.

  8. Development of a Canadian deceased donation education program for health professionals: a needs assessment survey. (United States)

    Hancock, Jennifer; Shemie, Sam D; Lotherington, Ken; Appleby, Amber; Hall, Richard


    The purpose of this survey was to determine how Canadian healthcare professionals perceive their deficiencies and educational requirements related to organ and tissue donation. We surveyed 641 intensive care unit (ICU) physicians, 1,349 ICU nurses, 1,561 emergency room (ER) physicians, and 1,873 ER nurses. The survey was distributed by the national organization for each profession (the Canadian Association of Emergency Physicians, the Canadian Association of Critical Care Nurses, and the National Emergency Nurses Association). Canadian Blood Services developed the critical care physician list in collaboration with the Canadian Critical Care Society. Survey development included questions related to comfort with, and knowledge of, key competencies in organ and tissue donation. Eight hundred thirty-one (15.3%) of a possible 5,424 respondents participated in the survey. Over 50% of respondents rated the following topics as highly important: knowledge of general organ and tissue donation, neurological determination of death, donation after cardiac death, and medical-legal donation issues. High competency comfort levels ranged from 14.7-50.9% for ICU nurses and 8.0-34.6% for ER nurses. Competency comfort levels were higher for ICU physicians (67.5-85.6%) than for ER physicians who rated all competencies lower. Respondents identified a need for a curriculum on national organ donation and preferred e-learning as the method of education. Both ICU nurses and ER practitioners expressed low comfort levels with their competencies regarding organ donation. Intensive care unit physicians had a much higher level of comfort; however, the majority of these respondents were specialty trained and working in academic centres with active donation and transplant programs. A national organ donation curriculum is needed.

  9. Motives for Donating: What Inspires Our Decisions to Make a Donation to Non-profit Organisations?1

    Directory of Open Access Journals (Sweden)

    Hladká Marie


    Full Text Available Motivation represents a foundation cornerstone on which analyses in a number of humanities and social sciences are built. For a long time, economists have seen motivation as connected with the act of giving, trying to interpret it in the context of the neoclassical economics assumptions. The objective of this paper is to find answers to the question of what mainly motivates the Czech population in their decisions to make a donation and whether there is any interdependence among such motives. We also ask what the relationship is between the determining motives and the rate or frequency of donating. The donation models that we analyze and use as the basis of our research are nowadays considered being the principal or at least interesting donation models commonly taken into account by economists in their work. We have only focused on selected microeconomics models to make the text clearly targeted; specifically, we are examining the public goods model, private consumption model investment model and impure altruism model. The data were collected through a questionnaire survey and analysed by means of mathematical-statistical methods that are commonly used in similar cases, such as descriptive statistics, the Pearson correlation coefficient and the ANOVA method based on the F-test. The empirical testing confirmed several assumptions connecting with this type of a research; however, our paper opened a space for a follow-up research, too.

  10. Comparison of equations for estimating glomerular filtration rate in screening for chronic kidney disease in asymptomatic black Africans: a cross sectional study. (United States)

    Omuse, Geoffrey; Maina, Daniel; Mwangi, Jane; Wambua, Caroline; Kanyua, Alice; Kagotho, Elizabeth; Amayo, Angela; Ojwang, Peter; Erasmus, Rajiv


    Several equations have been developed to estimate glomerular filtration rate (eGFR). The common equations used were derived from populations predominantly comprised of Caucasians with chronic kidney disease (CKD). Some of the equations provide a correction factor for African-Americans due to their relatively increased muscle mass and this has been extrapolated to black Africans. Studies carried out in Africa in patients with CKD suggest that using this correction factor for the black African race may not be appropriate. However, these studies were not carried out in healthy individuals and as such the extrapolation of the findings to an asymptomatic black African population is questionable. We sought to compare the proportion of asymptomatic black Africans reported as having reduced eGFR using various eGFR equations. We further compared the association between known risk factors for CKD with eGFR determined using the different equations. We used participant and laboratory data collected as part of a global reference interval study conducted by the Committee of Reference Intervals and Decision Limits (C-RIDL) under the International Federation of Clinical Chemistry (IFCC). Serum creatinine values were used to calculate eGFR using the Cockcroft-Gault (CG), re-expressed 4 variable modified diet in renal disease (4v-MDRD), full age spectrum (FAS) and chronic kidney disease epidemiology collaboration equations (CKD-EPI). CKD classification based on eGFR was determined for every participant. A total of 533 participants were included comprising 273 (51.2%) females. The 4v-MDRD equation without correction for race classified the least number of participants (61.7%) as having an eGFR equivalent to CKD stage G1 compared to 93.6% for CKD-EPI with correction for race. Only age had a statistically significant linear association with eGFR across all equations after performing multiple regression analysis. The multiple correlation coefficients for CKD risk factors were higher for

  11. Attitudes and beliefs about deceased organ donation in the Arabic-speaking community in Australia: a focus group study (United States)

    Ralph, Angelique F; Alyami, Ali; Allen, Richard D M; Howard, Kirsten; Craig, Jonathan C; Chadban, Steve J; Irving, Michelle; Tong, Allison


    Objectives To describe the beliefs and attitudes to organ donation in the Arabic-speaking community. Design Arabic-speaking participants were purposively recruited to participate in 6 focus groups. Transcripts were analysed thematically. Participants 53 participants, aged 19–77 years, and originating from 8 countries, participated in 1 of 6 focus groups. Participants identified as Christian (73%), Islam (26%), Buddhist (2%) or did not identify with any religion (2%). Results 6 themes (with subthemes) were identified; religious conviction; invisibility of organ donation; medical suspicion; owning the decision; and reciprocal benefit. Conclusions Although organ donation is considered a generous life-saving ‘gift’, representative members of the Arabic-speaking community in Australia were unfamiliar with, unnerved by and sceptical about the donation process. Making positive decisions about organ donation would likely require resolving tensions between respecting family, community and religious values versus their individual autonomy. Providing targeted education about the process and benefits of organ donation within the Arabic community may clarify ambiguities surrounding cultural and religious-based views on organ donation, reduce taboos and suspicion towards donation, and in turn, lead to increased organ donation rates.

  12. Complications associated with blood donations in a blood bank at an Indian tertiary care hospital. (United States)

    Meena, Monika; Jindal, Tarun


    Blood donation, though safe, has a few potentially avoidable complications associated with it. They are important reasons for the failure of the donors to return for repeat donations. The aim of this study was to assess the frequency and identify the possible factors associated with increased risk of blood donation related complications so that they can be minimized. A prospective study was done over a period of four months in the blood bank of an Indian tertiary care hospital to record the donation related complications. Out of 7450 blood donations, total donation associated complications were 74, of which majority were vasovagal reactions (VVRs) (n=48), followed by venous hematomas (n=24) and arterial punctures (n=2). The incidence of VVRs was more, though not statistically significant, in females, replacement/repeat donors, donors between 21-30 y of age and who had a body-mass-index (BMI) of 18.5-24.9. VVRs were more common in April (p=0.002) and in those who donated 450ml of blood (pdonated 350ml of blood, statistically significant association was seen only in repeat donors (pdonation in our country has a complication rate of nearly 1%.

  13. Corneal donations in South Africa: A 15-year review. (United States)

    York, Nicholas J; Tinley, Christopher


    Corneal pathology is one of the leading causes of preventable blindness in South Africa (SA). A corneal transplant can restore or significantly improve vision in most cases. However, in SA there is a gross shortage of corneal tissue available to ophthalmologists. Little has been published describing the magnitude of the problem. To describe trends in the number of corneal donors per year in SA, the number of corneal transplants performed each year, the origin of donors, the allocation of corneas to the public or private sector, and the demographics of donors. This was a retrospective review of all corneal donations to SA eye banks over the 15-year period 1 January 2002 - 31 December 2016. There was a progressive year-on-year decline in corneal donors over the study period, from 565 per year in 2002 to 89 in 2016. As a direct result, there has been an 85.5% decrease in the number of corneal transplants performed per year using locally donated corneas, from 1 049 in 2002 to 152 in 2016. Of the donors, 48.8% originated from mortuaries, 39.0% from private hospitals and 12.2% from government hospitals; donors from mortuaries showed the most significant decline over the 15-year period, decreasing by 94.8%. Of donated corneas, 79.3% were allocated to the private sector and 21.7% to the public sector. Males comprised 69.1% of donors, while 77.2% were white, 14.0% coloured, 6.3% black and 2.5% Indian/Asian. Donor age demonstrated a bimodal peak at 25 and 55 years. The number of corneal donations in SA has declined markedly, causing the burden of corneal disease requiring transplantation to rise steadily. Population groups with a low donor rate may have cultural and other objections to corneal donation, which should be a major focus of future research and initiatives aimed at reversing the current trends.

  14. Female College Students' Perceptions of Organ Donation (United States)

    Boland, Kathleen; Baker, Kerrie


    The current process of organ donation in the U.S. relies on the premise of altruism or voluntary consent. Yet, human organs available for donation and transplant do not meet current demands. The literature has suggested that college students, who represent a large group of potential healthy organ donors, often are not part of donor pools. Before…

  16. A Qualitative Study of Turning Points or Aha! Moments in Older Adults' Discussions About Organ Donation. (United States)

    Downing, Kimberly; Jones, Linda L


    Older adults (50-70 years old) have lower organ donor registration rates than younger adults. Older adults have different informational needs and donor registration behavior than younger age groups. The objective of this qualitative study was to understand insights of older adults about organ donation to effectively address the barriers to becoming an organ donor. This study identified turning points as "Aha!" moments that occurred during a dialogue intervention where older adults discussed benefits, barriers, and process to organ donation. Dialogues were held with small groups of older adults in 11 communities in a Midwestern organ procurement organization service area. Participants were positive to organ donation, but not registered as an organ donor. Methods/Approach: Qualitative analysis of verbatim comments from the dialogue and a follow-up survey were used to examine turning points or "Aha!" moments of participants' decision-making about organ donation and organ donor registration. Twenty-one separate in-depth dialogues were conducted with 198 participants, with mean age of 60.57 years. There were 2757 separate comments coded with 465 of the comments (17%) identified as providing Aha! moments during the dialogue. Three themes include benefits of organ donation (30%), barriers about organ donation (39%), and organ donation process (31%). The research identified moments in the dialogue where possible learning about organ donation may have occurred. After participation in the dialogue process, there was an increase in intent to register to be an organ donor, organ donation discussion with family and friends, and organ donor registration.

  18. Knowledge and Attitudes Toward Organ Donation in Health Care Undergraduate Students in Italy. (United States)

    Fontana, F; Massari, M; Giovannini, L; Alfano, G; Cappelli, G


    The number of organ donors in Italy is increasing, but with still disappointing living donation activity and relatively frequent objection by potential deceased donors' relatives to organ recovery. Few studies have assessed health care students' knowledge and attitude on donation. We administered a questionnaire to medical (MS) and nursing students (NS) at University of Modena and Reggio Emilia, Italy, and 749 students (406 MS and 343 NS) completed the questionnaire. Although 95% of students were in favor of donation, only 21.9% of NS and 24.9% of MS were registered as donors. One quarter of students reported family disagreement. MS appeared more confident with personnel involved in donation. Overall, 60% of students knew the term donation after brain death but only 40% were aware of the criteria used to define it. Barely 27.1% of NS and 15.3% of MS believed they had received sufficient information in lessons. Backward logistic regression demonstrated that students whose families agree with them and who knew the definition of donation after brain death were more likely to express the disposition of registering, and those who showed distrust in the declaration of brain death were half as likely to register as donors. Students expressed a lack of knowledge, controversial attitudes on donation, and strong need for education; increased awareness may help increase donation rates. The majority of educational institutions in Italy do not directly address training on organ donation and transplantation for health care students; an integrated curriculum favoring interpersonal discussion including practical aspects is urgently required.

    On May 12, 2008, a severe earthquake struck China's Sichuan Province. The nationwide outpouring of charity resulted in a surge of subsequent blood donations. The quantity and quality of these donations were examined in comparison with routine donations. Whole blood and apheresis donations from five geographically different blood centers collected within 1 week postearthquake were compared with those collected during the rest of the year. Regional differences, demographic characteristics, first-time and repeat donor status, and infectious disease screening markers associated with these donations were compared by earthquake status using chi-square statistics. Poisson regression analysis examined the number of daily donations by earthquake status after adjusting for center, day of week, and seasonal variations. The number of daily donations across five blood centers increased from 685 on a typical day to 1151 in the postearthquake week. The surge was observed in both sexes and across different education levels, age, and ethnicity groups and three blood centers and was significant after adjusting for confounding covariates. The influx of first-time donors (89.5%) was higher than that of repeat donors (34%). There was a significant change in the overall screening reactive marker rates excluding alanine aminotransferase (2.06% vs. 1.72%% vs. 4.96%). However, when the individual screening test was analyzed separately, no significant differences were found. Timely donations in response to a disaster are crucial to ensure emergency blood transfusion. The dramatically increased postearthquake donations suggest that Chinese blood centers are capable of handling emergency blood needs. Measures to maintain blood safety should be taken in times of emergency. © 2010 American Association of Blood Banks.

  20. Family Over Rules? An Ethical Analysis of Allowing Families to Overrule Donation Intentions. (United States)

    Shaw, David; Georgieva, Denie; Haase, Bernadette; Gardiner, Dale; Lewis, Penney; Jansen, Nichon; Wind, Tineke; Samuel, Undine; McDonald, Maryon; Ploeg, Rutger


    Millions of people want to donate their organs after they die for transplantation, and many of them have registered their wish to do so or told their family and friends about their decision. For most of them, however, this wish is unlikely to be fulfilled, as only a small number of deaths (1% in the United Kingdom) occur in circumstances where the opportunity to donate organs is possible. Even for those who do die in the "right" way and have recorded their wishes or live in a jurisdiction with a "presumed consent" system, donation often does not go ahead because of another issue: their families refuse to allow donation to proceed. In some jurisdictions, the rate of "family overrule" is over 10%. In this article, we provide a systematic ethical analysis of the family overrule of donation of solid organs by deceased patients, and examine arguments both in favor of and against allowing relatives to "veto" the potential donor's intentions. First, we provide a brief review of the different consent systems in various European countries, and the ramifications for family overrule. Next, we describe and discuss the arguments in favor of permitting donation intentions to be overruled, and then the arguments against doing so. The "pro" arguments are: overrule minimises family distress and staff stress; families need to cooperate for donation to take place; families might have evidence regarding refusal; and failure to permit overrules could weaken trust in the donation system. The "con" arguments are: overrule violates the patient's wishes; the family is too distressed and will regret the decision; overruling harms other patients; and regulations prohibit overrule. We conclude with a general discussion and recommendations for dealing with families who wish to overrule donation. Overall, overrule should only rarely be permitted.

  1. Evaluation of the Motivation to Consent to and to Refuse Organ Donation Among Participants of Educational Meetings Concerning Organ Transplantation. (United States)

    Milaniak, I; Wilczek-Rużyczka, E; Wierzbicki, K; Sadowski, J; Kapelak, B; Przybyłowski, P


    Improvement of the consent rate for solid organ donation from deceased donors is a key component of strategies applied in many countries aiming to increase the availability of organs for transplantation. Attitudes toward living and posthumous donation are favorable. Research shows that the outlook on organ donation and the degree of the willingness to become an organ donor are associated with a wide range of variables. The main objective of this study was to identify factors that influence the willingness to donate organs and the reasons for refusing consent. The study included 191 participants (135 female and 56 male) aged 16 to 61 years (mean age 26.86 ± 12.88). A cross-sectional study was conducted during educational meetings concerning organ donation that was addressed to students, teachers, and nurses. Survey tools included the Individual Questionnaire: Study of attitudes toward transplantation, consisting of 26 closed questions (with the consent of the Statistical Office in Krakow). In all, 97.4% of the respondents accepted transplantation from living donors, and 95.8% accepted deceased donations. Of the respondents, 78.5% agreed to posthumous life-saving organ donation. There was a significant difference between the respondents' sex, age, social group, place of living, and the reasons for their willingness to donate organs both posthumously and during their lifetime, as well as reasons for refusal. Our findings showed that the study group in general had favorable views on treatment involving transplantation and declared willingness to make a posthumous organ donation. These views vary depending on demographic variables. The education on the subject of organ and tissue donation has a positive impact on donation and transplantation rates.

  2. End-stage kidney disease among indigenous peoples of Australia and New Zealand. (United States)

    McDonald, Stephen P


    Although possessing different anthropological origins, there are similarities in the epidemiology of end-stage kidney disease (ESKD) among the indigenous peoples of Australia (the Australian Aborigines and Torres Strait Islanders) and New Zealand (Maori and Pacific Peoples). In both countries there is a substantially increased rate of ESKD among these groups. This is more marked in Australia than in New Zealand, but in both countries the relative rate (in comparison to non-indigenous rates) as well as absolute rate have nearly stabilized in recent years. The excess risk affects females particularly-in contrast to the non-indigenous picture. Among Aboriginal and Torres Strait Islander people in Australia, there is a strong age interaction, with the most marked risk being among those aged 25 to 45 years. Indigenous peoples are less likely to be treated with home dialysis, and much less likely to receive a kidney transplant. In particular, rates of living donation are very low among indigenous groups in both countries. Outcomes during dialysis treatment and during transplantation are inferior to those of nonindigenous ones, even after adjustment for the higher prevalence of comorbidities. The underlying causes for these differences are complex, but the slowing and possible stabilization of incident rate changes is heartening.

    The Uruguayan population is sensitized toward transplantation. However, it has not been studied how this awareness can change when emigrating to different countries. To analyze the attitude toward cadaveric organ donation and living organ donation between the Uruguayan population residing in Florida (United States) and the Uruguayan population residing in Spain. Adults born in Uruguay and residing in Florida and Spain were screened. The questionnaire "PCID-DTO Ríos" (donation of cadaveric organs) and "PCID-DVR Ríos" (living renal donation) were used. Subjects were randomly selected according to age and gender stratification. Support from Latin-American immigration associations in Spain and Florida was needed. The survey was anonymized and self-administered. Verbal consent was obtained to collaborate in the study. Because the emigrant population to Spain is far larger than the emigrant population to the United States, a 2:1 proportional sampling was performed (n = 132). Sixty-seven percent of residents in Spain were in favor of organ donation at the time of death compared with 50% among residents in Florida (P = .082), and 100% of residents in Spain were in favor of living renal donation compared with 50% of those living in Florida (P donation is more favorable among Uruguayan emigrants to Spain than emigrants to the United States, especially in related kidney donation.

  7. Estimated glomerular filtration rate is a poor predictor of the concentration of middle molecular weight uremic solutes in chronic kidney disease.

    Directory of Open Access Journals (Sweden)

    Nathalie Neirynck

    Full Text Available BACKGROUND: Uremic solute concentration increases as Glomerular Filtration Rate (GFR declines. Weak associations were demonstrated between estimated GFR (eGFR and the concentrations of several small water-soluble and protein-bound uremic solutes (MW500 Da. MATERIALS AND METHODS: In 95 CKD-patients (CKD-stage 2-5 not on dialysis, associations between different eGFR-formulae (creatinine, Cystatin C-based or both and the natural logarithm of the concentration of several LMWP's were analyzed: i.e. parathyroid hormone (PTH, Cystatin C (CystC, interleukin-6 (IL-6, tumor necrosis factor-alpha (TNF-α, leptin, retinol binding protein (RbP, immunoglobin light chains kappa and lambda (Ig-κ and Ig-λ, beta-2-microglobulin (β(2M, myoglobin and fibroblast growth factor-23 (FGF-23. RESULTS: The regression coefficients (R(2 between eGFR, based on the CKD-EPI-Crea-CystC-formula as reference, and the examined LMWP's could be divided into three groups. Most of the LMWP's associated weakly (R(2 0.7. Almost identical R(2-values were found per LMWP for all eGFR-formulae, with exception of CystC and β(2M which showed weaker associations with creatinine-based than with CystC-based eGFR. CONCLUSION: The association between eGFR and the concentration of several LMWP's is inconsistent, with in general low R(2-values. Thus, the use of eGFR to evaluate kidney function does not reflect the concentration of several LMWP's with proven toxic impact in CKD.

    The need to expand the organ donor pool remains a formidable challenge in kidney transplantation (KT). The use of expanded criteria donors (ECDs) represents one approach, but kidney discard rates are high because of concerns regarding overall quality. Dual KT (DKT) may reduce organ discard and optimize the use of kidneys from marginal donors. We conducted a single-center retrospective review of outcomes in adult recipients of DKTs from adult marginal deceased donors (DD) defined by limited renal functional capacity. If the calculated creatinine clearance in an adult DD was DKT. Over 11.5 yr, 72 DKTS were performed including 45 from ECDs, 17 from donation after cardiac death (DCD) donors, and 10 from standard criteria donors (SCD). Mean adult DD and recipient ages were both 60 yr, including 29 DDs and 26 recipients ≥65 yr of age. Mean pre-DKT waiting and dialysis vintage times were 12 months and 25 months, respectively. Actual patient and graft survival rates were 84.7% and 70.8%, respectively, with a mean follow-up of 58 months. One yr and death-censored graft survival rates were 90% and 80%, respectively. Outcomes did not differ by DD category, recipient age, or presence of delayed graft function (DGF). Eleven patients died at a mean of 32 months post-DKT (eight with functioning grafts) and 13 other patients experienced graft losses at a mean of 33 months. The incidence of DGF was 25%; there were two cases (2.8%) of primary non-function. Mean length of initial hospital stay was 7.2 d. Mean serum creatinine and glomerular filtration rate levels at 12 and 24 months were 1.5 and 53 and 1.5 mg/dL and 51 mL/min/1.73 m(2) , respectively. DKT graft survival and function were superior to concurrent single ECD and similar to concurrent SCD KTs. Two patients underwent successful kidney retransplantation, so the dialysis-free rate in surviving patients was 87%. The proportion of total renal function transplanted from adult DD to DKT recipients was 77% compared to 56% for

  9. Increasing living donor kidney transplantation numbers in Budapest. (United States)

    Bäcker, H; Piros, L; Langer, R M


    Living related kidney donations (LRD) have had a significant impact on therapy of kidney diseases. Due to their ease of scheduling in the general surgery program and better half-life of about 21.6 versus 13.8 years for deceased donor kidneys, this approach has revolutionized nephrology and transplantation medicine. Since the first Hungarian LRD which was performed in 1974 in Budapest, Hungary, donations have expanded especially in the last 3 years. This has been followed in 2000 by living unrelated kidney donations (LURD). Since 2000 LURD can be also performed in Hungary. From the 251 LRD in our country in the last 3 years, 79 living donations have accounted for nearly one-third of the cases. In comparison of 2008, and 2011 the absolute numbers of LRD as well as LURD have more than doubled from 9 to 20 and 6 to 14 respectively. Based on international ranking data from the global observatory on donation and transplantation Budapest has improved from 1.20 in 2000 to 6.20 LRD per million persons (p.m.p.) in 2010. The increase in LURD has also led to some side effects: an increase in recipient age from 26 years in 2000 to 46 in 2011 and greater HLA mismatches. In 2010, Budapest ranked higher than Croatia or Portugal but still behind Germany (8.13 LRD p.m.p.) and the leading countries: the Netherlands (28.49 LRD p.m.p.) and Norway (16.94 LRD p.m.p.). Because of the tremendous progress in LRD, the gap between today's leading countries and Budapest is closing. Copyright © 2013 Elsevier Inc. All rights reserved.

  10. Non-donors' attitudes towards sperm donation and their willingness to donate. (United States)

    Provoost, Veerle; Van Rompuy, Florence; Pennings, Guido


    The aim of this article is to study attitudes about sperm donation and willingness to donate sperm in students who have never shown an interest in sperm donation. The method used in this study is an electronic survey of 1012 male students. Only one third of the respondents (34.3%) would consider donating sperm. Overall, 85.7% indicated a positive attitude towards sperm donation while 14.3% indicated a neutral or negative attitude. The highest scored barriers to donating were the lack of practical information and the fear that the partner would not agree. Almost 40% of the respondents feared that the donation might have a negative impact on their current or future relationship. The majority (83.6%) of those who considered donating thought donors should receive a financial compensation. Money was also one of the main motivators. About 85% of the students thought positively about sperm donation but several factors such as perceived negative views by the social environment, especially the partner, may deter students from donating. This study indicates that the effect of strong incentives, for instance in monetary terms, on a donor pool consisting of students could be limited and that relational factors and donor's perceptions of the views of the wider social network should be taken into account when recruiting donors.

  11. Achievements and barriers in the organ donation process: a critical analysis of donation coordinators' discourse. (United States)

    Mercado-Martínez, Francisco J; Díaz-Medina, Blanca A; Hernández-Ibarra, Eduardo


    Donation coordinators play an important role in the success or failure of organ donation and transplant programs. Nevertheless, these professionals' perspectives and practices have hardly been explored, particularly in low- and middle-income countries. To examine donation coordinators' discourse on the organ donation process and the barriers they perceive. A critical qualitative study was carried out in Guadalajara, Mexico. Twelve donation coordinators from public and private hospitals participated. DATA GATHERING AND ANALYSIS: Data were gathered by using semistructured interviews and critical discourse analysis. Participants indicated that partial results have been achieved in deceased organ donation. Concomitantly, multiple obstacles have adversely affected the process and outcomes: at the structural level, the fragmentation of the health system and the scarcity of financial and material resources; at the relational level, nonegalitarian relationships between coordinators and hospital personnel; at the ideational level, the transplant domain and its specialists overshadow the donation domain and its coordinators. Negative images are associated with donation coordinators. Organ donation faces structural, relational, and ideational barriers; hence, complex interventions should be undertaken. Donation coordinators also should be recognized by the health system.

  12. Risk factors for complications in donors at first and repeat whole blood donation: a cohort study with assessment of the impact on donor return. (United States)

    Wiersum-Osselton, Johanna C; Marijt-van der Kreek, Tanneke; Brand, Anneke; Veldhuizen, Ingrid; van der Bom, Johanna G; de Kort, Wim


    First-time donation is among recognised risk factors for vasovagal reactions to blood donation and reactions are known to reduce donor return. We assessed associations between potential risk factors and vasovagal reactions and needle-related complications in first-time whole blood donation in comparison to repeat donation and analysed the impact of complications on donor return. We performed a cohort study on whole blood donations in The Netherlands from 1/1/2010 to 31/12/2010 using data extracted from the blood service information system. Donation data up to 31/12/2011 were used to ascertain donor return. In 2010 28,786 donors made first whole blood donations and there were 522,958 repeat donations. Vasovagal reactions occurred in 3.9% of first donations by males and 3.5% of first donations by females compared to in 0.2% and 0.6%, respectively, of repeat donations. Associations of vasovagal reactions with other factors including age, body weight, systolic and diastolic blood pressure were similar in first-time and repeat donors. Needle-related complications occurred in 0.2% of male and 0.5% of female first-time donations and in 0.1% and 0.3%, respectively, of repeat donations. Among first-time donors, the return rate within 1 year was 82% following an uncomplicated first donation, but 55% and 61% following vasovagal reactions and needle-related complications, respectively; the corresponding percentages among repeat donors were 86%, 58% and 82%. Among first-time donors, females suffered less than males from vasovagal reactions. Other risk factors had similar associations among first-time and repeat donors. Vasovagal reactions and needle-related complications in both first-time and repeat donors are followed by reduced donor return.

  14. Breast milk donation: women's donor experience. (United States)

    Alencar, Lucienne Christine Estevez de; Seidl, Eliane Maria Fleury


    To describe the characteristics of donation behavior and identify reasons, beliefs and feelings relative to this practice, based on the reports of donor women. Personal and social-environmental aspects, which seem to affect donation behavior in donors and former donors, were also investigated. An exploratory, descriptive and cross-sectional study was carried out with women donors at two breast-milk banks within the public health system of the Brazilian Federal District. Data was collected from July to September 2005. The participants were 36 women, aged 14 to 33 years (average=24.78; SD=5.22), with different levels of schooling, 58.3% of which were first-time mothers. Data gathering was based on interviews carried out during home visits. In addition to descriptive statistical analyses of quantitative data, a qualitative data categorical analysis was also performed. The most frequently reported reasons for donating breast milk were altruism and excess milk production. The most frequent time interval for donation was 13 days after delivery. Contact by phone with the milk bank was the most common means of communication used by the majority of participants (n=22) to obtain information that enabled the donating process. Psychosocial aspects identified and the experience of donors can contribute to the empowerment of the formal and informal social donation-support network, in addition to serving as a driver for the implementation of technical and policy strategies in promoting future donation practices.

  15. Prevalence of human immunodeficiency virus, syphilis, hepatitis B and C in blood donations in Namibia. (United States)

    Mavenyengwa, Rooyen T; Mukesi, Munyaradzi; Chipare, Israel; Shoombe, Esra


    Transfusion Transmissible Infections (TTIs) such as Human Immunodeficiency Virus (HIV), syphilis, hepatitis B virus (HBV) and hepatitis C virus (HCV) are infections which are common in some communities in Southern Africa. It is important to screen blood donations for these infections. This is a retrospective study which involved reviewing of previous blood donation records for the year 2012 in Namibia. The records were analyzed to determine the prevalence of HIV, syphilis, Hepatitis B and C among blood donations with regard to gender, age and geographical region of the donors. The findings indicated a significantly low prevalence of HIV, syphilis, HBsAg and anti-Hepatitis C among the blood donations. A low infection rate of 1.3% by any of the four tested TTIs was found among the blood donations given by the donor population in Namibia in 2012. The blood donations given by the donor population in Namibia has a low infection rate with the HIV, syphilis, HBsAg and anti-HCV. A strict screening regime must continue to be used as the infections are still present albeit in small numbers.

  16. Assessing Transplant Attitudes: Understanding Minority Men's Perspectives on the Multifarious Barriers to Organ Donation. (United States)

    Hinck, Bryan D; Naelitz, Bryan D; Jackson, Brielle; Howard, Mariah; Nowacki, Amy; Modlin, Charles S


    African Americans comprise 11 % of living organ donors, yet constitute 34 % of the kidney transplant waiting list. There are many barriers to organ donation among minorities that include decreased awareness of transplantation, cultural mistrust of the medical community, financial concerns, and fear of the transplant operation. This study investigates the societal misconceptions and demographic health factors that correlate with minority participation in organ and tissue donation. A 57 question Health and Wellness survey was designed to assess participants' demographic information, medical history, professional background, and opinions regarding organ transplantation. Participants were also asked to complete Quality Metric's Short Form-8 (SF-8) survey to assess physical health, mental health, and quality-of-life. Three hundred twenty-six surveys were administered to minority men. The majority of men were identified as African American, and 55 % were below the age of 40. Though 44 % of participants were willing to donate, only 27 % were registered as organ and tissue donors. Minorities who held misconceptions about organ donation-including the belief that they were too old or unhealthy to donate, for example-had lower general, physical, and mental health scores than those who did not (p = Minorities aware of the shortage for organs or who know a registered donor, an organ recipient, a dialysis patient, or someone on the waiting list were more willing to donate organs. Improving the general, physical, and mental health of minorities, coupled with an active educational outreach program, could result in a greater percentage of minorities registering and willing to be organ and tissue donors.

  17. Stress influences environmental donation behavior in men. (United States)

    Sollberger, Silja; Bernauer, Thomas; Ehlert, Ulrike


    Stress has been found to have both positive and negative effects on prosocial behavior, suggesting the involvement of moderating factors such as context and underlying motives. In the present study, we investigated the conditions under which acute stress leads to an increase vs. decrease in environmental donation behavior as an indicator of prosocial behavior. In particular, we examined whether the effects of stress depended on preexisting pro-environmental orientation and stage of the donation decision (whether or not to donate vs. the amount to be donated). Male participants with either high (N=40) or low (N=39) pro-environmental orientation were randomly assigned to a social stress test or a control condition. Salivary cortisol was assessed repeatedly before and after stress induction. At the end of the experiment, all subjects were presented with an opportunity to donate a portion of their monetary compensation to a climate protection foundation. We found that stress significantly increased donation frequency, but only in subjects with low pro-environmental orientation. Congruously, their decision to donate was positively associated with cortisol response to the stress test and the emotion regulation strategy mood repair, as well as accompanied by an increase in subjective calmness. In contrast, among the participants who decided to donate, stress significantly reduced the donated amount of money, regardless of pro-environmental orientation. In conclusion, our findings suggest that acute stress might generally activate more self-serving motivations, such as making oneself feel better and securing one's own material interests. Importantly, however, a strong pro-environmental orientation partially prevented these effects. Copyright © 2015 Elsevier Ltd. All rights reserved.

  18. What would encourage blood donation in Ireland? (United States)

    Harrington, M; Sweeney, M R; Bailie, K; Morris, K; Kennedy, A; Boilson, A; O'Riordan, J; Staines, A


    Recent changes have resulted in the loss of 4% of the donor panel in the Republic of Ireland and 3% in Northern Ireland. In order to increase the number of donors in these two regions, it is important that transfusion service providers explore and understand the reasons, which prevent individuals from donating. The aim of this study was to explore these issues particularly in non-donors and those who had lapsed. This 7-month all-Ireland study was conducted by computer-assisted telephone interview. Data collected included sociodemographic history, donation status, as well as barriers/deterrents to donation. There were 4166 completed questionnaires (44% donors; 56% non-donors). Of the donors, 13% had donated blood within the last 2 years. Current donors cited 'awareness of patients needs' (88%), 'trust in the blood transfusion service' (70%), and 'an advertising campaign' (70%) as reasons encouraging them to donate blood. Lapsed donors and non-donors cited 'more frequent mobile clinics/sessions' (30% lapsed donors; 53% non-donors), 'if I was asked' (28% lapsed donors; 53% non-donors), and 'more flexible opening hours' (23% lapsed donors; 44% non-donors) as reasons that would encourage them to donate. The main reasons cited by non-donors for never having donated included 'medical reasons' (41% Republic of Ireland; 43% Northern Ireland), 'lack of information' (20% Republic of Ireland; 22% Northern Ireland), 'fear of needles' (15% Republic of Ireland; 17% Northern Ireland), and 'time constraints' (12% Republic of Ireland; 13% Northern Ireland). Among the non-donor group, 10% (Republic of Ireland) and 6% (Northern Ireland) claimed that they are not permitted to donate. Replacing regular donors is a major challenge for the transfusion service providers. This study shows that by facilitating the general public by introducing more mobile clinics/sessions, more flexible opening hours and having a better level of knowledge in the community about blood donation may encourage

  19. Attitudes and Perception Towards Eye Donation in Patients with Corneal Disease: A Case-controlled Population-based Study. (United States)

    Noopur, Gupta; Praveen, Vashist; Radhika, Tandon; Sanjeev K, Gupta; Mani, Kalaivani; Deepak, Kumar


    To assess awareness, barriers, and misconceptions related to eye donation in people with corneal disease as compared to controls in a population setting. A population-based study was conducted in 25 randomly selected clusters of Rural Gurgaon, Haryana, India, as part of the CORE (Cornea Opacity Rural Epidemiological) study. In addition to ophthalmic examination, knowledge and perceptions regarding eye donation were assessed through a validated questionnaire. The questionnaire captured the sociodemographic factors influencing awareness regarding eye donation in participants with corneal disease and twice the number of age- and gender-matched controls recruited from the same study clusters. Descriptive statistics were computed along with multivariable logistic regression analysis to determine associated factors for awareness of eye donation. In the CORE study, 452 participants had corneal opacities on ocular examination. Of these, 442 were assessed for eye donation awareness. Additionally, 884 age- and gender-matched controls were recruited. The mean age of cases and controls was 60.9 ± 15.5 and 59.6 ± 14.3 years, respectively. Awareness of eye donation in cases and controls was 46.4% (n = 205 of 442) and 52.3% (n = 462 of 884), respectively (P = 0.044). Educational status was an important factor determining knowledge about eye donation in both cases and controls (P = donated before death or even after 24 h of death and that any type of blindness could be treated with corneal transplantation were prevalent. The study demonstrated that although there is substantial awareness about eye donation, there are numerous barriers in this population that need to be resolved to improve donation rates. Additional efforts are needed to translate this awareness into actual eye donation in both cases with corneal disease and controls.

  20. Perceptions of the gift relationship in organ and tissue donation: Views of intensivists and donor and recipient coordinators. (United States)

    Shaw, Rhonda


    The international literature on organ donation and transplantation has drawn attention to the popularity of "gift of life" discourse among pro-donation advocates, transplantation specialists, and within organisations lobbying for improved donation rates to promote the benefits of organ donation among members of the general public. In Aotearoa/New Zealand, gift of life discourse is robust. Aside from attempts to elicit altruism by promoting tissue donation in the public domain, gift terminology separates the act of donation from that of commerce and the commodification of body tissues. In distancing donation from commodification and the potential to degrade and exploit human beings, it is assumed that gift discourse transmits the positive message that donation is a noble and morally worthy act. Recent sociological research has shown that assumptions of the gift as one-way and altruistic do not necessarily align with people's perceptions and experience of donating body tissues, and that the vocabulary used to describe these acts is often at variance with reality. This article draws on interview data with 15 critical care specialists (intensivists) and donor and recipient coordinators, examining their perceptions of the relevance of gift discourse and its applicability in the context of deceased donation in Aotearoa/New Zealand. The data indicate several problems with gift rhetoric to describe the situations health professionals encounter. In sum, gift terminology tends to downplay the sacrifice involved in tissue donation generally, as well as depoliticising the exchange relations of tissue transfer in contemporary consumer culture and in the global context. This raises questions about the underlying ethics of language choice and what, if anything, empirical accounts of tissue transfer can contribute to ethical debates. Copyright 2009 Elsevier Ltd.

  1. Independent organ donor facilities: The future of organ donation? (United States)

    Bruzzone, Paolo


    more vasosuppressor support, which can be a study bias. It has been proposed that OPOs should organize "recovery teams" for multiple TCs but most transplant surgeons, in case of marginal donors, would like to inspect the organ prior to starting recipient surgery or would send their own team to harvest organs. According to literature, there are no other independent OFOs in US, probably because there is no need for them, and increasing their numbers would not increase organ donation rate. Considering Europe, we do not have information about the existence of independent OFOs: this may be a consequence of logistical organization and minor distances, as well as the higher concentration of TCs. However, the acceptance of such a procedure from donors' families may be less enthusiastic in Europe than in USA, particularly from minorities. In Italy would not be acceptable that the maintenance of BD donors and more generally the operation of independent OFO would rely on non-physicians, to save costs. Finally it is not clear from the reviewed papers who pay for transportation of the donor's body from the independent OFO back to home, but donor's family should not be charged for these expenses. At least 5 donors were lost during transportation, confirming that moving of BD donors remains a risky procedure. The potential economical and organizative benefits of independent OFOs could be counterweighted by the perceived (by relatives and public opinion) commodification/ reification of BD patients. Anyway, the authors of these papers should be congratulated for their innovative proposal. However, a prospective randomized trial would be needed to draw more definitive conclusions on the real benefits of independent OFOs.

  11. Public Opinion on Organ Donation After Death and Its Influence on Attitudes Toward Organ Donation. (United States)

    Aijing, Luo; Wenzhao, Xie; Wei, Wei; Qiquan, Wan; Xuantong, Deng


    BACKGROUND China officially launched a pilot program of organ donation after cardiac death to overcome the shortage of available organs since 2011. Voluntary organ donation by deceased citizens became the only source of transplant organs beginning January 1, 2015. To investigate public opinions on organ donation by deceased donors, and discuss the effect of these opinions on the willingness and attitude of the public regarding voluntary organ donation. MATERIAL AND METHODS We designed a questionnaire. The survey was conducted from December 2014 to January 2015 in Changsha City, and 417 valid questionnaires were recovered. RESULTS A total of 162 respondents explicitly expressed a willingness to donate organs, and 269 believed that the organ donors' relatives should be compensated. A total of 255 respondents thought it acceptable to complete the donation-consent form when receiving a driver's license. Among the respondents, 65.3% did not agree with the statement "My body is bestowed by my parents, and to donate my body parts would not display filial respect"; 88.9% agreed that "It is necessary to consider the willingness of my family"; 74.4% agreed that "Donated organs have not been fairly and appropriately used; the wealthy and celebrities have been favored"; and 61.4% agreed that "Organ donation laws and regulations are not well developed, and organ donations will result in unnecessary difficulties." More than 80% believed that organ donation and transplantation extend life. CONCLUSIONS Public opinions on organ donation after death are associated with various factors, including traditional values, religious beliefs, compensation mechanisms, donor registration, institutional credibility, and ideals.

  12. A Study on the Directed Living Non-Related Donor Kidney Transplantation Submitted to the Hospital Transplant Ethics Committee at the National Kidney and Transplant Institute. (United States)

    Suguitan, G; Arakama, M-H I; Danguilan, R


    In the latter part of 2009, the Department of Health of the Philippines prohibited kidney transplantation with non-related kidney donors. Hence, the National Kidney and Transplant Institute created a Hospital Transplant Ethics Committee. This study describes directed non-related kidney donation at the National Kidney and Transplant Institute. This retrospective study reviewed the profiles of recipients and directed living non-related kidney transplant donors submitted to the Hospital Transplant Ethics Committee. A total 74 recipients and donors were reviewed by the Hospital Transplant Ethics Committee in 2014. Donors initiated the talks about being a donor (75%) to repay the good deeds that were done by the recipient for them or their families; examples of which are: sometime in their lives they needed financial assistance for hospitalization for their relatives and it was the patient who paid the hospital bill; or because they pitied the recipient, whom they found to be a good person, thus they would want to give one of their kidneys. Seventy-four (100%) said that they were not expecting anything in return for this act but wanted to be of help to the recipient. Of these 74 cases, 70 cases (95%) were approved and the others were disapproved. With a Hospital Transplant Ethics Committee in place, directed kidney donation is a valuable tool as an additional source of kidney donor without violating any ethical issues. Copyright © 2016.

  13. Outcome of referrals for deceased organ donation to the government organ procurement organization. (United States)

    Suguitan, G A; Cabanayan-Casasola, C B; Danguilan, R A; Jaro, J M A


    The Human Organ Preservation Effort is a government organ procurement organization that pioneered the Deceased Organ Donation Program in the Philippines. Deceased organ donation comprises only 20% of kidney transplantation in the Philippines in the last 3 years. Various measures were implemented to improve deceased organ donor referrals and organ retrieval. To compare outcome of deceased organ donor referrals from 2002 to 2008 and 2009 to 2012 in the Philippines. This retrospective study reviewed the deceased organ donor referrals from 2002 to 2008 and 2009 to 2012. There were 437 referrals for potential deceased organ donors from 2009 to 2012, compared to 434 referrals from 2002 to 2008. Referrals were mainly trauma victims (76%) followed by those with cerebrovascular accidents (12%). In the recent cohort, 81% were approached and 60% consented for donation, but only 23% were retrieved and transplanted. Among those not retrieved, the majority (19%) were medically unsuitable and 6% retracted their consent. Although there was an increasing trend of organ donation referrals in the last 4 years, only 25% were procured. The reasons for nonprocurement should be addressed. Copyright © 2014 Elsevier Inc.

    Casadio, Maria Chiara; Coppo, Anna; Vargiolu, Alessia; Villa, Jacopo; Rota, Matteo; Avalli, Leonello; Citerio, Giuseppe


    In a consecutive cohort of cardiac arrest (CA) treated with extracorporeal cardiopulmonary resuscitation (eCPR), we describe the incidence of brain death (BD), the eligibility for organ donation and the short-term follow-up of the transplanted organs. All refractory in- and out-of-hospital CA admitted to our Cardiac Intensive Care Unit between January 2011 and September 2016 treated with eCPR were enrolled in the study. 112 CA patients received eCPR. 82 (73.2%) died in hospital, 25 BD (22.3%) and 57 for other causes (50.9%). At the time of first neurological evaluation after rewarming, variables related to evolution to BD were a lower GCS (3 [3-3] vs. 8 [3-11], pdonation in BD patients was 56%, with 39 donated organs: 23 kidneys, 12 livers, and 4 lungs. 89.74% of the transplanted organs reached an early good functional recovery. In refractory CA patients treated with eCPR, the prevalence of BD is high. This population has a high potential for considering organ donation. Donated organs have a good outcome.

  15. Organ transplant education: the way to form altruistic behaviors among secondary school students toward organ donation. (United States)

    Milaniak, I; Przybylowski, P; Wierzbicki, K; Sadowski, J


    Organ shortage for transplantation is a crucial problem all over the world. Educational intervention may appeal to young people's altruism, increasing organ donation and decreasing the opposition. This study assessed the influence of an educational program, including organ donation and transplantation, to forming students' altruistic behaviors. A total 680 students of 25 secondary schools were asked about their attitudes, intentions, and knowledge about organ donation and transplantation from September 2008 to June 2009 during a 45-minute lesson. In this study, altruistic attitudes were measured through questions about the expression of will to give organs away after death; to give one kidney to relatives; to use the bone marrow from a foreign person; and to sign a donor card. Attitudes were assessed by questions about conversations with relatives, an evaluation of the educational project. More than 1500 donor card were distributed and more than 90% of students wanted to sign them; 73.6% agreed to sign a donor card with the ID card. Before the project, only 8% of students had a signed donor card. Almost everybody is ready to agree to give their organs after death (80.6% male; 92.2% female), or to relatives (100% male; 90.38% female), or bone marrow (80% male; 55.7% female). The students talked to their family, informing them about their decision (36.9% male; 45.9% female). The proposed educational project successfully encouraged teenagers to make well-considered choices with regard to organ donation and created altruistic behaviors.

  16. Chronic Kidney Disease. (United States)

    Webster, Angela C; Nagler, Evi V; Morton, Rachael L; Masson, Philip


    The definition and classification of chronic kidney disease (CKD) have evolved over time, but current international guidelines define this condition as decreased kidney function shown by glomerular filtration rate (GFR) of less than 60 mL/min per 1·73 m 2 , or markers of kidney damage, or both, of at least 3 months duration, regardless of the underlying cause. Diabetes and hypertension are the main causes of CKD in all high-income and middle-income countries, and also in many low-income countries. Incidence, prevalence, and progression of CKD also vary within countries by ethnicity and social determinants of health, possibly through epigenetic influence. Many people are asymptomatic or have non-specific symptoms such as lethargy, itch, or loss of appetite. Diagnosis is commonly made after chance findings from screening tests (urinary dipstick or blood tests), or when symptoms become severe. The best available indicator of overall kidney function is GFR, which is measured either via exogenous markers (eg, DTPA, iohexol), or estimated using equations. Presence of proteinuria is associated with increased risk of progression of CKD and death. Kidney biopsy samples can show definitive evidence of CKD, through common changes such as glomerular sclerosis, tubular atrophy, and interstitial fibrosis. Complications include anaemia due to reduced production of erythropoietin by the kidney; reduced red blood cell survival and iron deficiency; and mineral bone disease caused by disturbed vitamin D, calcium, and phosphate metabolism. People with CKD are five to ten times more likely to die prematurely than they are to progress to end stage kidney disease. This increased risk of death rises exponentially as kidney function worsens and is largely attributable to death from cardiovascular disease, although cancer incidence and mortality are also increased. Health-related quality of life is substantially lower for people with CKD than for the general population, and falls as GFR

  17. The challenges of social marketing of organ donation: news and entertainment coverage of donation and transplantation. (United States)

    Harrison, Tyler R; Morgan, Susan E; Chewning, Lisa V


    While great strides have been made in persuading the public to become potential organ donors, actual behavior has not yet caught up with the nearly universally favorable attitudes the public expresses toward donation. This paper explores the issue by situating the social marketing of organ donation against a broader backdrop of entertainment and news media coverage of organ donation. Organ donation storylines are featured on broadcast television in medical and legal dramas, soap operas, and other television serials approximately four times per month (not including most cable networks), and feature storylines that promote myths and fears of the organ donation process. National news and other non-fictionalized coverage of organ donation are even more common, with stories appearing over twenty times a month on average. These stories tend to be one-dimensional and highly sensationalized in their coverage. The marketing of organ donation for entertainment essentially creates a counter-campaign to organ donation, with greater resources and reach than social marketers have access to. Understanding the broader environmental context of organ donation messages highlights the issues faced by social marketing campaigns in persuading the public to become potential donors.

  18. Intra-Family Gamete Donation: A Solution to Concerns Regarding Gamete Donation in China? (United States)

    Liao, Juhong; Devolder, Katrien


    Gamete donation from third parties is controversial in China as it severs blood ties, which are considered of utmost importance in Confucian tradition. In recent years, infertile couples are increasingly demonstrating a preference for the use of gametes donated by family members to conceive children-known as "intra-family gamete donation." The main advantage of intra-family gamete donation is that it maintains blood ties between children and both parents. To date there is no practice of intra-family gamete donation in China. In this paper, we investigate intra-family adoption in China in order to illustrate that intra-family gamete donation is consistent with Confucian tradition regarding the importance of maintaining blood ties within the family. There are several specific ethical issues raised by intra-family gamete donation. It may, for example, result in consanguinity and the semblance of incest, lead to confused family relationships, and raise concerns about possible coercion of familial donors. Confucian tradition provides a new approach to understand and deal with these ethical issues in a way that Western tradition does not. As a result, we suggest intra-family gamete donation could be an acceptable solution to the problem of infertility in China. However, further discussion and open debates on the ethical issues raised by intra-family gamete donation are needed in China.

  19. The kidneys

    International Nuclear Information System (INIS)

    Freeman, L.M.; Lutzker, L.G.


    It has unfortunately remained true that radionuclide renal imaging studies have not been so widely accepted as other types of scintigraphy, despite improvements in radiopharmaceuticals and imaging techniques. Perhaps this is because of the variety of established radiologic techniques available for the study of the kidneys and the addition of new modalities such as CT scanning and ultrasound. Clinicians may have become confused by the multiplicity of options, which has obscured the distinction between renal scintigraphy and all other methods of imaging the kidney, i.e., that renal scintigraphy provides functional information in an easily quantifiable form. It is interesting that pediatric practitioners have more easily recognized the functional importance of this modality than have the practitioners of adult medicine, who more often prefer anatomic modalities, either traditional or new

  20. Blood donation on posters: a worldwide review. (United States)

    Lefrère, Jean-Jacques; Danic, Bruno


    Originally pasted on walls and on locations reserved specially for that purpose, the poster is a medium for advertising and promotion to be seen on the streets and in public places. More recently, it has spread, in a smaller format, on dedicated indoor sites: billboards, columns, street furniture, and so forth. For transfusion, it appeared early on that the poster constitutes an important medium to promote blood donation. Thousands of posters supporting regional, national, or international blood donation campaigns have been created all over the planet, with a great variability of images, symbols, and slogans, which are particularly revealing about the image and the reality of blood donation. The topic is rich in information, particularly sociologic, on the variety of ways in which transfusion organizations promote blood donation. The authors present in this article the results of a study based on a total of 283 posters from nations on every continent, divided into 24 different themes. © 2011 American Association of Blood Banks.

  3. Views and attitudes towards blood donation: a qualitative investigation of Indian non-donors living in England. (United States)

    Joshi, Dhaara; Meakin, Richard


    To explore the views and attitudes of Indians living in England on blood donation. In light of the predicted shortages in blood supply, it is vital to consider ways in which to maximise donation rates. These include addressing the issue of lower donation rates among ethnic minorities, including Indians. However research specifically among minority ethnicities in UK is sparse. General practice in North London. A convenience sample of 12 non-donor Indians living in England. This is a qualitative investigation involving semistructured interviews. Themes derived were analysed using thematic framework analysis. Five key themes emerged from the data, and these concerned participants' perspectives regarding attitudes towards blood, blood donation as a 'good thing', donation disincentives, the recipient matters and the donor matters. A variety of attitudes were presented, but were generally positive, and blood was conceptualised in a manner previously found to be consistent with donation. However, lack of awareness and accessibility were prominent barriers, indicating the need for improvement in these capacities. In contrast to this, blood was also greatly associated with family and acted as a symbol of kinship: this 'emotional charge' often acted to dissuade participants from separating with their blood through donation. Possibly due to this, there was also a strong preference for donated blood to be distributed within the family, as opposed to strangers. This presents a potential barrier to blood donation for some Indians within the current system in which donations are given to unknown recipients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Full Text Available OBJECTIVE: To establish equations for the estimation of glomerular filtration rates (eGFRs based on serum creatinine (SCr and/or serum cystatin C (SCysC in Chinese patients with chronic kidney disease (CKD, and to compare the new equations with both the reference GFR (rGFR and the literature equations to evaluate their applicability. METHODS: The 788 Chinese CKD patients were randomly divided into two groups, the training group and the testing group, to establish new eGFR-formulas based on serum CysC and to validate the established formulas, respectively. (99mTc-DTPA clearance (as the rGFR, serum Cr, and serum CysC were determined for all patients, and GFR was calculated using the Cockcroft-Gault equation (eGFR1, the MDRD formula (eGFR2, the CKD-EPI formulas (eGFR3, eGFR4, and the Chinese eGFR Investigation Collaboration formulas (eGFR5, eGFR6. The accuracy of each eGFR was compared with the rGFR. RESULTS: The training and testing groups' mean GFRs were 50.84±31.36 mL/min/1.73 m(2 and 54.16±29.45 mL/min/1.73 m(2, respectively. The two newly developed eGFR formulas were fitted using iterative computation: [Formula: see text] and [Formula: see text]. Significant correlation was observed between each eGFR and the rGFR. However, proportional errors and constant errors were observed between rGFR and eGFR1, eGFR2, eGFR4, eGFR5 or eGFR6, and constant errors were observed between eGFR3 and rGFR, as revealed by the Passing & Bablok plot analysis. The Bland-Altman analysis illustrated that the 95% limits of agreement of all equations exceeded the previously accepted limits of <60 mL/min •1.73 m(2, except the equations of eGFR7 and eGFR8. CONCLUSION: The newly developed formulas, eGFR7 and eGFR8, provide precise and accurate GFR estimation using serum CysC detection alone or in combination with serum Cr detection. Differences in detection methods should be carefully considered when choosing literature eGFR equations to avoid misdiagnosis and

  5. Adverse outcomes of anticoagulant use among hospitalized patients with chronic kidney disease: a comparison of the rates of major bleeding events between unfractionated heparin and enoxaparin.

    Full Text Available BACKGROUND: Anticoagulation therapy is usually required in patients with chronic kidney disease (CKD for treatment or prevention of thromboembolic diseases. However, this benefit could easily be offset by the risk of bleeding. OBJECTIVES: To determine the incidence of adverse outcomes of anticoagulants in hospitalized patients with CKD, and to compare the rates of major bleeding events between the unfractionated heparin (UFH and enoxaparin users. METHODS: One year prospective observational study was conducted in patients with CKD stages 3 to 5 (estimated GFR, 10-59 ml/min/1.73 m(2 who were admitted to the renal unit of Dubai Hospital. Propensity scores for the use of anticoagulants, estimated for each of the 488 patients, were used to identify a cohort of 117 pairs of patients. Cox regression method was used to estimate association between anticoagulant use and adverse outcomes. RESULTS: Major bleeding occurred in 1 in 3 patients who received anticoagulation during hospitalization (hazard ratio [HR], 4.61 [95% confidence interval [CI], 2.05-10.35]. Compared with enoxaparin users, patients who received anticoagulation with unfractionated heparin had a lower mean [SD] serum level of platelet counts (139.95 [113] × 10(3/µL vs 205.56 [123] × 10(3/µL; P<0.001, and had a higher risk of major bleeding (HR, 4.79 [95% CI, 1.85-12.36]. Furthermore, compared with those who did not receive anticoagulants, patients who did had a higher in-hospital mortality (HR, 2.54 [95% CI, 1.03-6.25]; longer length of hospitalization (HR, 1.04 [95% CI, 1.01-1.06]; and higher hospital readmission at 30 days (HR, 1.79 [95% CI, 1.10-2.91]. CONCLUSIONS: Anticoagulation among hospitalized patients with CKD was significantly associated with an increased risk of bleeding and in-hospital mortality. Hence, intensive monitoring and preventive measures such as laboratory monitoring and/or dose adjustment are warranted.

A retrospective chart review was performed to collect data about recipient demographics, etiology of end-stage kidney disease, type of dialysis, type of donor and outcome. Between September 2008 and April 2012, 35 pediatric kidney trans-plantations (need to encourage preemptive transplantation and living donation in this population.

  8. [Marketing role of corneal graft tissue donation to an eye bank and donors' socioeconomic profile]. (United States)

    Farias, Roberta Jansen de Mello; Sousa, Luciene Barbosa de


    Penetrating keratoplasty has been the leading and the most successful type of transplant in the world, however corneal deficiency is a commom problem usually presented to corneal surgeons. Impact evaluation of the number of corneal graft donations to the Sorocaba Eye Bank after the implementation of a corneal graft procurement system; to draw the socioeconomic profile of corneal graft donors of the Sorocaba Eye Bank (SEB). Retrospective study on donations to SEB from its creation and after the development of media marketing. Prospective analysis of the socioeconomic profile of corneal graft donors by a questionnaire sent as letters to the families of the donors in a certain month. SEB began its work in 1971 by spreading need of organ donation through lectures in churches, shopping malls, community meetings, radio programs, television programs, etc. In the 70s, the number of retrieved corneal grafts was 1 or 2/month. Between 1984 - 1989 a procurement coordination team was trained to act in mortuaries and by 2000 they also began to work in public hospitals. In 1984 only 260 corneal grafts were retrieved. This number has been increasing to 2,778 corneal graft donations in 2004. The questionnaire was answered by 76 of the 93 donor families, with a response rate of 81.7%. Donor age had a mean of 65.1 +/- 14.7 y/o, forty-two (55.3%) were men. Educational level of the donor families was an important factor for organ donation, once 36.8% had concluded high school and 34.2% completed university. The great majority, sixty-three (82.9%) of the corneal grafts were donated through the efforts of the procurement coordination team. The role of the media and institutional credibility are mandatory for public commitment to organ donation. The proficiency of the procurement coordination team requires intensive training, as the results show that 82.9% donations were made thanks to their efforts.

  9. Reassessing marketing of kidneys from the 2008 perspective. (United States)

    Friedman, Eli A; Friedman, Amy L


    Progressive improvements in all aspects of the kidney transplant regimen establish this form of renal replacement therapy as superior to peritoneal or hemodialysis in terms of extent of rehabilitation and long-term recipient survival. Continuous growth in the number of patients with kidney failure sustained by dialytic therapy has not been associated with substantially increased deceased donor kidney contributions, causing intensified stressful waiting periods for potential recipients lacking a live kidney donor. Neither public relation campaigns nor local government efforts have substantially increased kidney donation. Buying a donor kidney is illegal and condemned as fostering exploitation of poor people by the wealthy. Widely publicized examples of coercion of unwilling donors create a negative image of harmful, inhumane conduct deployed to obtain kidneys sold and transplanted under unsavory circumstances. Yet efforts to establish and test governmental programs to supervise and sustain acceptable standards for the sale and implantation of kidneys from fully informed, medically evaluated and protected, fairly compensated donors have been resisted and frustrated by those who consider such compensation loathsome. Accordingly, while selling kidneys is prohibited by law, pressure from those wanting to quench the number of deaths of wait-listed dialysis patients continues forcing reexamination of an issue that, like prohibition of the possession and sale of alcohol in the United States in 1920, places the will of a people in opposition to unreasonably restrictive laws. The debate continues.

  10. Evaluating deceased organ donation: a programme theory approach. (United States)

    Manzano, Ana; Pawson, Ray


    Organ donation and transplantation services represent a microcosm of modern healthcare organisations. They are complex adaptive systems. They face perpetual problems of matching supply and demand. They operate under fierce time and resource constraints. And yet they have received relatively little attention from a systems perspective. The purpose of this paper is to consider some of the fundamental issues in evaluating, improving and policy reform in such complex systems. The paper advocates an approach based on programme theory evaluation. The paper explains how the death to donation to transplantation process depends on the accumulation of series of embedded, institutional sub-processes. Evaluators need to be concerned with this whole system rather than with its discrete parts or sectors. Policy makers may expect disappointment if they seek to improve donation rates by applying nudges or administrative reforms at a single point in the implementation chain. These services represent concentrated, perfect storms of complexity and the paper offers guidance to practitioners with bio-medical backgrounds on how such services might be evaluated and improved. For the methodological audience the paper caters for the burgeoning interest in programme theory evaluation while illustrating the design phase of this research strategy.

    Montero Salinas, Alejandro; Martínez-Isasi, Santiago; Fieira Costa, Eva; Fernández García, Antón; Castro Dios, Diana Josefa; Fernández García, Daniel


    The Spanish model is the model adopted by many countries to increase their donation rate, being the implication of the healthcare professionals one of the keys to this success. The attitude of these before the donation is crucial for the hour of influence on the population. Organ transplantation has been established as an effective treatment that has been improving over the years. The objective was to determine the knowledge and attitudes of health professionals before the donation of organs. Cross-sectional descriptive study. An ad hoc questionnaire was conducted and distributed among the health professionals (medical staff, nurses and nursing assistants) of a tertiary hospital during February 2015. A total of 615 potential participants were estimated in the different areas of the hospital. A total of 342 completed questionnaires were collected (55%). The statistical analysis with SPSS® Statistics for Windows. Version 20.0. A level of significance P lower than 0.05 was used in all the analyses. The average age of the respondents was 43.34 (SD = 10.37) years, being 86.6% women and 60% nurses. 35.5% showed good knowledge about the donation process, being higher in men (51.1% Vs 33.1%, p lower than 0.05), medical personnel (55% vs 34.3% vs 31.9%). %; p lower than 0.05) and lower in those services with a direct relationship with the donation process (36.8% vs 31.9%, p lower than 0.05). 71% of the professionals expressed their willingness to donate their organs, with special sensitivity towards donation those services in direct relation with the donation program (82.2% vs 65.9%, OR: 1.24, p lower than 0.001 ). 50% of the professionals would donate the organs of a family member; the medical group had the highest percentage (70% vs 50.7% vs 40.4%, OR: 3.8, p lower than 0.05). 74.5% knew some Spanish legal document about donation and transplants. Health professionals as a whole have a low level of knowledge; but a good attitude towards donation.

    Health workers' awareness and knowledge of transplantation medicine can improve people's sensitivity and reduce their degree of opposition to donations. The medical literature contains numerous examples of attitudes toward organ transplantation and donation aimed at university students or medical staff members, but rarely for transplantation nurses. The purposes of the study were to investigate the attitudes toward organ transplantation and donation among transplantation nurses and to explore the impact factors. The study was conducted in 37 transplantation surgery wards in 22 hospitals using cross-sectional approach. SPSS (International Business Machines Corporation, Armonk, New York, USA) 7.0 software was used to analysis descriptive and inferential statistics for data. Five hundred thirty-six effective questionnaires were received and the effective rate was 89.33%. Nurses' mean age was 28.40 years with a mean service length of 6.54 years. Among these nurses, 66.6% and 78.0% were willing to accept organ transplantation surgery for themselves and their relatives, respectively. Of these nurses, 33.4% would donate their organs after death; whereas 39.9% were uncertain. Only 38.2% were willing to register in the national organ donation system. Of these nurses, 28.2% were willing to sign the organ donation consent forms when their relatives became potential organ donors, and 45.7% were uncertain. Eight independent variables that affected nurses' attitudes toward donating their organs from most to least significant were: ratio of nurse to bed, title, employment form, age, length of service, position, monthly income, and the highest educational degree earned. Pearson correlation analysis showed a significant correlation among nurses' attitudes toward organ transplantation, organ donation, and online registration. The attitude toward donation and transplantation in the hospitals was not too optimistic, and an improvement in the training regarding transplantation and

  13. Experiences of Women Who Donated Human Milk. (United States)

    Candelaria, Laura M; Spatz, Diane L; Giordano, Noreen


    To examine the experiences of women who donated breast milk to a hospital-based milk bank regulated under the policies and procedures set forth by the Human Milk Banking Association of North America (HMBANA). Qualitative, phenomenological design. The Mothers' Milk Bank in a children's hospital in the Northeastern region of the United States. Twelve HMBANA-approved milk donors older than 21 years with infants hospitalized in the NICU. Edmund Husserl's design of interpretive phenomenology and Colaizzi's method of data analysis were used for this study. Participants were interviewed using a face-to-face, semistructured interview format. Four themes represented the experience of donating breast milk: Ripple of Hope and Help, Dynamic Interplay of Nurturance, Standing on the Shoulders of Others, and Sharing Their Stories. Donors felt proud and accomplished to provide hope for other infants and families. Nurses were crucial in facilitating and motivating donors and making donation achievable in a supportive environment. Donors felt compelled to share their experiences to teach and motivate others to donate. For our participants, donation of human milk was a positive, valuable, and nurturing experience. Donors reported feelings of increased self-esteem during donation that motivated them to "give back" and continue. The support of a well-trained nursing staff is essential for donors to meet their personal goals. Copyright © 2018 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

    Hepatitis E virus (HEV) poses a risk to transfusion safety. In Australia, locally acquired HEV is rare and cases are mainly reported in travelers returning from countries endemic for HEV. The risk posed by HEV to transfusion safety in Australia is unknown; therefore, we aimed to measure the rate of current HEV infection in Australian blood donations. A total of 14,799 blood donations were tested for HEV RNA by transcription-mediated amplification, with confirmatory testing by reverse transcription-polymerase chain reaction. Viral load quantification and phylogenetic analysis was performed on HEV RNA-positive samples. One (0.0068%; 95% confidence interval [CI], 0.0002%-0.0376%) sample was confirmed positive for HEV RNA, resulting in a risk of collecting a HEV-viremic donation of 1 in 14,799 (95% CI, 1 in 584,530 to 1 in 2,657). The viral load in this sample was approximately 15,000 IU/mL, and it was determined to be Genotype 3. Our finding of 1 in 14,799 Australian donations positive for HEV RNA is lower than that from many other developed countries; this is consistent with the relatively low seroprevalence in Australia. As this HEV RNA-positive sample was Genotype 3, it seems likely that this infection was acquired through zoonotic transmission, either within Australia or overseas in a developed nation. HEV has the potential to pose a risk to transfusion safety in Australia; however, additional, larger studies are required to quantify the magnitude of this risk. © 2016 AABB.

  15. Delayed Referral Results in Missed Opportunities for Organ Donation After Circulatory Death. (United States)

    Krmpotic, Kristina; Payne, Clare; Isenor, Cynthia; Dhanani, Sonny


    Rates of organ donation and transplantation have steadily increased in the United States and Canada over the past decade, largely attributable to a notable increase in donation after circulatory death. However, the number of patients awaiting solid organ transplantation continues to remain much higher than the number of organs transplanted each year. The objective of this study was to determine the potential to increase donation rates further by identifying gaps in the well-established donation after circulatory death process in Ontario. Retrospective cohort study. Provincial organ procurement organization. Patients who died in designated donation hospitals within the province of Ontario, Canada between April 1, 2013, and March 31, 2015. None. Of 1,407 patient deaths following planned withdrawal of life-sustaining therapy, 54.0% (n = 760) were medically suitable for donation after circulatory death. In 438 cases where next of kin was approached, consent rates reached 47.5%. A total of 119 patients became actual organ donors. Only 66.2% (n = 503) of suitable patients were appropriately referred, resulting in 251 missed potential donors whose next of kin could not be approached regarding organ donation because referral occurred after initiation of withdrawal of life-sustaining therapy or not at all. The number of medically suitable patients who die within 2 hours of planned withdrawal of life-sustaining therapy is nearly six times higher than the number of actual organ donors, with the greatest loss of potential due to delayed referral until at the time of or after planned withdrawal of life-sustaining therapy. Intensive care teams are not meeting their ethical responsibility to recognize impending death and appropriately refer potential organ donors to the local organ procurement organization. In cases where patients had previously registered their consent decision, they were denied a healthcare right.

  16. CERN servers donated to Ghana

    CERN Multimedia

    CERN Bulletin


    Cutting-edge research requires a constantly high performance of the computing equipment. At the CERN Computing Centre, computers typically need to be replaced after about four years of use. However, while servers may be withdrawn from cutting-edge use, they are still good for other uses elsewhere. This week, 220 servers and 30 routers were donated to the Kwame Nkrumah University of Science and Technology (KNUST) in Ghana.   “KNUST will provide a good home for these computers. The university has also developed a plan for using them to develop scientific collaboration with CERN,” said John Ellis, a professor at King’s College London and a visiting professor in CERN’s Theory Group.  John Ellis was heavily involved in building the relationship with Ghana, which started in 2006 when a Ghanaian participated in the CERN openlab student programme. Since 2007 CERN has hosted Ghanaians especially from KNUST in the framework of the CERN Summer Student Progr...

  17. Free blood donation mobile applications. (United States)

    Ouhbi, Sofia; Fernández-Alemán, José Luis; Toval, Ambrosio; Idri, Ali; Pozo, José Rivera


    Blood donation (BD) is a noble act and mobile applications (apps) can help increase awareness about it. This paper analyzes and assesses the characteristics of free apps for BD as regards features and functionality. A search in Google Play, Apple Apps store, Blackberry App World and Windows Mobile App store was carried out to select 169 free BD apps from the 188 apps identified. The results presented in this paper show that the majority of the apps selected have been developed for the Android operating system. Moreover, most of the apps selected are available to help users search for donors. Few of the apps could not be installed and/or accessed. Of those that could be installed: half of them do not require any kind of authentication; a few of them are available in more than one language; half of them have a geographical restriction; around 60 % of them do not notify the user of BD events and requests; one, which is available for Android and iOS, can connect with a laboratory; around 45 % of them allow users to share information via social networks, and the majority of them do not provide BD recommendations. These results are used as a basis to provide app developers with certain recommendations. There is a need for better BD apps with more features in order to increase the number of volunteer donors.

  20. The importance of education in the promotion of organ donation

    Directory of Open Access Journals (Sweden)

    Taise Ribeiro Morais


    Full Text Available Transplantation and human organ donation are controversial issues that have generated much interest and discussion. The lack of clarification and the sensationalist news about organ trafficking contribute to raise questions and render the myths and prejudices permanent.The donation of organs and tissues is seen by society in general, as an act of solidarity and love from the family. However, it requires decision-making at a time of extreme pain and distress, caused by the impact of breaking news of death, the feeling of loss and the unexpected interruption of a life course(1.As the criteria of death are modified, the concept of brain death arises, along with the possibility of using donor organs and tissues. When there is not a good understanding of the organ donation process, the relatives of potential donors feel apprehensive, doubtful and undecided at the time of occurrence, because it is a subject about which there hasn’t been much clarification(1.Brazil has the largest public transplants program in the world, since the government finances 92% of procedures done in the country. However, when we consider the rate of post mortem transplant into the population, Brazil’s results are little expressive(2.Family refusal is a major obstacle to the realization of transplants, and is also identified as major cause for the shortage of organs and tissues for transplantation. Families who understand well the diagnosis of brain death are more favorable to organ donation, compared to families who believe that death only occurs after the heart stops. Therefore, the poor level of information, either by the quality of information concerning brain death, either by not having exceeded the barrier of stigmatized fear of organ trading, propagated by the media, drastically reduces the number of patients who are benefited from receiving an organ(3.Although all people are responsible for disseminating information, we must also educate health professionals, since

  1. Blood donation by African migrants and refugees in Australia: the role of demographic and socio-economic factors. (United States)

    McQuilten, Z; Waters, N; Polonsky, M; Renzaho, A


    To establish blood donation rates among African refugees and migrants and identify demographic and socio-economic factors that are associated with their blood donation. A cross-sectional survey of 425 migrants and refugees living in Victoria and South Australia was used to assess blood donation status. The association between blood donation and demographic and socio-economic factors was assessed using multiple logistic regression analysis. Overall, 73 participants (17·2%; 95% CI: 13·6-20·8) reported having donated blood previously. Of the total sample, 2·4% (95% CI: 0·9-3·8) reported having given blood in Australia; 12·9% (95% CI: 9·7-16·1) had given blood prior to migration to Australia (i.e. country of birth or transition); and 1·9% (95% CI: 0·6-3·2) indicated they had given blood in an unspecified country. In the univariate model, age, country of birth, blood donation knowledge, religion, educational attainment, migration and employment status were all associated with blood donation status. However, in the multivariate model, only age >45 years (odds ratio [OR] 5·72; 95% CI 2·11-15·46), African region of origin (OR 15·89; 95% CI 3·89-65) and blood donation knowledge (OR 4·46; 95% CI 1·57-12·7) were associated with blood donation. In order to increase the number of blood donors among African migrants, promoting knowledge and awareness of issues associated with blood donation in Australia should be emphasized. Consideration should be given to identifying these potential migrant donors to improve the availability of compatible blood for patients of African descent. © 2013 International Society of Blood Transfusion.

  2. A Modified Protocol with Improved Detection Rate for Mis-Matched Donor HLA from Low Quantities of DNA in Urine Samples from Kidney Graft Recipients.

    Directory of Open Access Journals (Sweden)

    Janette Kwok

    Full Text Available Urine from kidney transplant recipient has proven to be a viable source for donor DNA. However, an optimized protocol would be required to determine mis-matched donor HLA specificities in view of the scarcity of DNA obtained in some cases.In this study, fresh early morning urine specimens were obtained from 155 kidney transplant recipients with known donor HLA phenotype. DNA was extracted and typing of HLA-A, B and DRB1 loci by polymerase chain reaction-specific sequence primers was performed using tailor-made condition according to the concentration of extracted DNA.HLA typing of DNA extracted from urine revealed both recipient and donor HLA phenotypes, allowing the deduction of the unknown donor HLA and hence the degree of HLA mis-match. By adopting the modified procedures, mis-matched donor HLA phenotypes were successfully deduced in all of 35 tested urine samples at DNA quantities spanning the range of 620-24,000 ng.This urine-based method offers a promising and reliable non-invasive means for the identification of mis-matched donor HLA antigens in kidney transplant recipients with unknown donor HLA phenotype or otherwise inadequate donor information.

  3. Attitudes to Organ Donation and Knowledge of Donation and Transplantation among University of Auckland Medical Students

    Full Text Available Aims • To explore organ donation and transplantation knowledge and attitudes among medical students at the University of Auckland. • To understand students' perception of the extent of training received prior to and during the medical program. Method A validated web-based questionnaire consisting of 42 questions in five categories was anonymously administered to all enrolled medical students at the Faculty of Medical and Health Sciences, University of Auckland, in September 2012. Results In all, 419 out of 989 (42% Year 2–6 students responded. A total of 99.3% of medical students supported organ donation, but knowledge was limited (mean score 7.54/15±2.26. A total of 38% of students reported having participated in organ donation learning. A total of 96% of students believed that organ donation information should be available in primary care settings. A total of 69% of students reported that if a patient asked a question about organ donation that they did not know the answer to, they also would not know where to source the correct information from. Conclusion This study demonstrates that although medical students support organ donation, they lack the knowledge required to facilitate informative discussions with patients. Enhanced organ donation education in medical programs may enable students to develop skills and knowledge allowing them to better discuss donation with patients.

    Al Shaer, Laila; Sharma, Ranjita; AbdulRahman, Mahera


    To ensure an adequate and safe blood supply, it is crucial to select suitable donors according to stringent eligibility criteria. Understanding the reasons for donor deferral can help in planning more efficient recruitment strategies and evaluating donor selection criteria. This study aims to define donor pre-donation deferral rates, causes of deferral, and characteristics of deferred donors in Dubai. This retrospective study was conducted on all donors who presented for allogeneic blood donation between January 1, 2010, until June 30, 2013, in Dubai Blood Donation Centre, accredited by the American Association of Blood Banks. The donation and deferral data were analyzed to determine the demographic characteristics of accepted and deferred donors, and frequency analyses were also conducted. Among 142,431 individuals presenting during the study period, 114,827 (80.6%) were accepted for donation, and 27,604 (19.4%) were deferred. The overall proportion of deferrals was higher among individuals less than 21 years old (35%, P Dubai is relatively high compared to the internationally reported rates. This rate was higher among first-time donors and females, with low hemoglobin as the major factor leading to a temporary deferral of donors. Strategies to mitigate deferral and improve blood donor retention are urged in Dubai to avoid additional stress on the blood supply.

  6. Does Confucianism allow for body donation? (United States)

    Jones, D Gareth; Nie, Jing-Bao


    Confucianism has been widely perceived as a major moral and cultural obstacle to the donation of bodies for anatomical purposes. The rationale for this is the Confucian stress on xiao (filial piety), whereby individuals' bodies are to be intact at death. In the view of many, the result is a prohibition on the donation of bodies to anatomy departments for the purpose of dissection. The role of dissection throughout the development of anatomy within a Confucian context is traced, and in contemporary China the establishment of donation programs and the appearance of memorial monuments is noted. In reassessing Confucian attitudes, the stress laid on a particular interpretation of filial piety is questioned, and an attempt is made to balance this with the Confucian emphasis on a moral duty to those outside one's immediate family. The authors argue that the fundamental Confucian norm ren (humaneness or benevolence) allows for body donation as people have a moral duty to help others. Moreover, the other central Confucian value, li (rites), offers important insights on how body donation should be performed as a communal activity, particularly the necessity of developing ethically and culturally appropriate rituals for body donation. In seeking to learn from this from a Western perspective, it is contended that in all societies the voluntary donation of bodies is a deeply human activity that is to reflect the characteristics of the community within which it takes place. This is in large part because it has educational and personal repercussions for students. Anat Sci Educ. © 2018 American Association of Anatomists. © 2018 American Association of Anatomists.

  7. [Organ donation after death in Moroccan population]. (United States)

    Esqalli, Imane; Knidiri, Hafssa; Mahoungou, Gael; Aitlahcen, Zineb; Fadili, Wafaa; Laouad, Inass


    Morocco stays far behind other countries in the domain of organ donation and transplantation. Improving the knowledge of Moroccan students, about organ donation and transplantation, can be a key factor in the development of transplant activity. The aim of this study is to evaluate the knowledge, attitudes and beliefs of students concerning organ donation and transplantation. The opinion survey was conducted in Marrakech city, with four high education structures with a pre-established questionnaire. The survey questions answered four main themes, which are: the evaluation of knowledge, the opinion and attitude of citizen, the explanation of refusal and the propositions to encourage organ donation in Morocco. Hundred percent of surveyed subjects answered the questionnaire. Among them, 40.3% were men. The middle age was 21.5 years. Out of 503 surveyed students, 89.4% were aware of organ transplant in Morocco. A quarter of students believed that removal and transplant acts were realized just in public health establishments, which have the authorization. Two persons out of 3 were able to identify transplantable organs and tissues. More than half accepted to donate their organs after death. The religious reason was in the head list of refusal determinants of organ donation after death, with a prevalence of 39.7%. Young Moroccans have limited knowledge relating to organ donation. The development of this therapy needs to establish an adequate project of information and motivation of general population. Copyright © 2015 Association Société de néphrologie.

  8. Estimating the Number of Organ Donors in Australian Hospitals—Implications for Monitoring Organ Donation Practices (United States)

    Pilcher, David; Gladkis, Laura; Arcia, Byron; Bailey, Michael; Cook, David; Cass, Yael; Opdam, Helen


    Background The Australian DonateLife Audit captures information on all deaths which occur in emergency departments, intensive care units and in those recently discharged from intensive care unit. This information provides the opportunity to estimate the number of donors expected, given present consent rates and contemporary donation practices. This may then allow benchmarking of performance between hospitals and jurisdictions. Our aim was to develop a method to estimate the number of donors using data from the DonateLife Audit on the basis of baseline patient characteristics alone. Methods All intubated patient deaths at contributing hospitals were analyzed. Univariate comparisons of donors to nondonors were performed. A logistic regression model was developed to estimate expected donor numbers from data collected between July 2012 and December 2013. This was validated using data from January to April 2014. Results Between July 2012 and April 2014, 6861 intubated patient deaths at 68 hospitals were listed on the DonateLife Audit of whom 553 (8.1%) were organ donors. Factors independently associated with organ donation included age, brain death, neurological diagnoses, chest x-ray findings, PaO2/FiO2, creatinine, alanine transaminase, cancer, cardiac arrest, chronic heart disease, and peripheral vascular disease. A highly discriminatory (area under the receiver operatory characteristic, 0.940 [95% confidence interval, 0.924-0.957]) and well-calibrated prediction model was developed which accurately estimated donor numbers. Three hospitals appeared to have higher numbers of actual donors than expected. Conclusions It is possible to estimate the expected number of organ donors. This may assist benchmarking of donation outcomes and interpretation of changes in donation rates over time. PMID:25919766

  9. Kidney Sales and Market Regulation: A Reply to Semrau. (United States)

    Koplin, Julian J


    Luke Semrau argues that the documented harms of existing organ markets do not undermine the case for establishing regulated systems of paid kidney donation. He offers two arguments in support of this conclusion. First, Semrau argues that the harms of kidney selling are straightforwardly amenable to regulatory solution. Second, Semrau argues that even in existing black markets, sellers would likely have experienced greater harm if the option of selling a kidney were not available. This commentary challenges both of Semrau's claims. I argue that there is no reason to believe that kidney sellers benefit from the current black market trade in organs, and highlight a number of potential issues regarding the effectiveness and feasibility of Semrau's proposed market regulations. © The Author 2017.

  15. Kidney transplantation in the elderly. (United States)

    Singh, Neeraj; Nori, Uday; Pesavento, Todd


    Recent outcome data, ongoing organ shortage and proposed changes in allocation policies are driving the need to review current practices and possible future course of kidney transplantation in the elderly patients. A proposed new kidney allocation system based on matching donor and recipient characteristics to enable 'age-matched' kidney allocation is currently being discussed in the USA. While this system benefits younger recipients, implications for elderly recipients receiving older grafts remain a matter of debate. Despite improved outcomes, there remain significant challenges to kidney transplantation in the elderly, including organ shortage, poor transplant rate, evolving allocation policies, high wait-list mortality and nonstandardized immunosuppression. Prospective studies are needed to evaluate the strategies to meet these challenges and to study the impact of proposed new allocation system.

  16. A Re-evaluation of Discarded Deceased Donor Kidneys in the UK: Are Usable Organs Still Being Discarded? (United States)

    Mittal, Shruti; Adamusiak, Anna; Horsfield, Catherine; Loukopoulos, Ioannis; Karydis, Nikolaos; Kessaris, Nicos; Drage, Martin; Olsburgh, Jonathon; Watson, Christopher Je; Callaghan, Chris J


    A significant proportion of procured deceased donor kidneys are subsequently discarded. The UK Kidney Fast-Track Scheme (KFTS) was introduced in 2012, enabling kidneys at risk of discard to be simultaneously offered to participating centers. We undertook an analysis of discarded kidneys to determine if unnecessary organ discard was still occurring since the KFTS was introduced. Between April and June 2015, senior surgeons independently inspected 31 consecutive discarded kidneys from throughout the United Kingdom. All kidneys were biopsied. Organs were categorized as usable, possibly usable pending histology, or not usable for implantation. After histology reports were available, final assessments of usability were made. There were 19 donors (6 donations after brain death, 13 donations after circulatory death), with a median (range) donor age of 67 (29-83) years and Kidney Donor Profile Index of 93 (19-100). Reasons for discard were variable. Only 3 discarded kidneys had not entered the KFTS. After initial assessment postdiscard, 11 kidneys were assessed as usable, with 9 kidneys thought to be possibly usable. Consideration of histological data reduced the number of kidneys thought usable to 10 (10/31; 32%). The KFTS scheme is successfully identifying organs at high risk of discard, though potentially transplantable organs are still being discarded. Analyses of discarded organs are essential to identify barriers to organ utilization and develop strategies to reduce unnecessary discard.

  17. Donations After Circulatory Death in Liver Transplant. (United States)

    Eren, Emre A; Latchana, Nicholas; Beal, Eliza; Hayes, Don; Whitson, Bryan; Black, Sylvester M


    The supply of liver grafts for treatment of end-stage liver disease continues to fall short of ongoing demands. Currently, most liver transplants originate from donations after brain death. Enhanced utilization of the present resources is prudent to address the needs of the population. Donation after circulatory or cardiac death is a mechanism whereby the availability of organs can be expanded. Donations after circulatory death pose unique challenges given their exposure to warm ischemia. Technical principles of donations after circulatory death procurement and pertinent studies investigating patient outcomes, graft outcomes, and complications are highlighted in this review. We also review associated risk factors to suggest potential avenues to achieve improved outcomes and reduced complications. Future considerations and alternative techniques of organ preservation are discussed, which may suggest novel strategies to enhance preservation and donor expansion through the use of marginal donors. Ultimately, without effective measures to bolster organ supply, donations after circulatory death should remain a consideration; however, an understanding of inherent risks and limitations is necessary.

  18. From motivation to acceptability: a survey of public attitudes towards organ donation in Denmark. (United States)

    Nordfalk, Francisca; Olejaz, Maria; Jensen, Anja M B; Skovgaard, Lea Larsen; Hoeyer, Klaus


    Over the past three decades, public attitudes to organ donation have been a subject of numerous studies focusing on donor motivation. Here, we present a fresh approach. We suggest focusing on public acceptability instead of motivation. The point is to understand public attitudes well enough to avoid risking public support for organ transplantation. We conducted the study in Denmark because there have been significant developments in public attitudes to organ donation in this country. In the 1990s, Denmark was a country with very low public support for organ donation and Denmark was the last country in Europe to introduce brain death as a legal criterion of death, whereas today Eurobarometer surveys rate Denmark as one of the European countries with the highest support for deceased organ donation from brain dead donors. We conducted a telephone survey in Denmark (N = 1195). A questionnaire was developed on the basis of preceding qualitative studies and pilot testing and included reuse of one item from earlier surveys to facilitate historical comparison. The analysis of the data was carried out using IBM SPSS Statistics 22 and focused on descriptive statistics. A clear majority of 91.9 % are positive or very positive towards organ donation; 85.8 % like the idea of their body being used after their death, 85.0 % is willing to donate their own organs, 82.1 % to donate their tissue and only 2.3 % find that too much has been done to promote organ donation. There is limited support for monetary incentives for organ donation (5.8 %) and presumed consent (30.4 %), while a majority (63.9 %) supports making it mandatory to register a personal decision. Religious self-identification has limited impact on attitudes. We can identify a shift over the past three decades from marked opposition to organ transplantation to strong support as well as a pattern in the contemporary public attitudes, which can help explain what is central to public acceptability: self

  19. The blood donation experience: self-reported motives and obstacles for donating blood. (United States)

    Sojka, B Nilsson; Sojka, P


    The aim of the study was to investigate motives for donating blood as well as difficulties and obstacles associated with blood donation as perceived by the donors themselves. Six hundred consecutive blood donors (i.e. all blood donors with a history of at least one previous whole blood donation attending, during nine working days, the Blood Centre of Umeå University Hospital) received a self-administered questionnaire that contained questions aimed at elucidating motives for donating blood (general motives for donating blood, specific motives for the first donation and motives for continuing to be an active blood donor). Questions concerning difficulties and obstacles that had to be overcome in order to continue being a blood donor were also included in the questionnaire. Altogether 531 whole blood donors filled in the questionnaire (88.5%; 322 men and 209 women). No statistically significant differences were found between male and female blood donors concerning general reasons and motives related to donating blood. The most frequently reported reasons for giving blood the first time were 'influence from a friend' (47.2% of donors) and 'request via media' (23.5% of donors). Among general reasons/motives with highest ranking of importance, the most commonly reported motive for donating blood were 'general altruism' (40.3%), 'social responsibility/obligation' (19.7%) and 'influence from friends' (17.9%). General altruism' and 'social responsibility/obligation' were also the most frequent reasons for continuing to donate blood (68.4 and 16.0%, respectively). The most commonly reported obstacle to becoming a regular blood donor was 'laziness' (19.1%) followed by 'fear of needles' (10.5%). Altruism was the most common general motive for donating blood and also for continuing to be an active blood donor. Yet, for the first blood donation, direct 'influence from friends/relatives', 'media appeal' and other types of recruitment were more commonly reported as reasons or

  20. [Blood donation: mechanic solidarity versus organic solidarity]. (United States)

    Pereima, Rosane Suely May Rodrigues; Reibnitz, Kenya Schmidt; Martini, Jussara Gue; Nitschke, Rosane Gonçalves


    The article offers a reflection of blood donation in an hemocenter of Santa Catarina, with a mechanic and organic solidarity approach. It discuss the way of life in contemporary globalization and the cult of speed in a context pervaded by uncertainties and adversities. People live in a fast world, making social interaction difficult, contributing to the weakening of values and attitudes that could improve the quality of life. Considering the difficulties of everyday contemporary society, concerning Brazilian hemotherapy history on blood donation, there is a perception that attitudes and values, such as solidarity, have been modifying in subtle ways with a background of current events. It searches for understanding of blood donation as mechanic and organic solidarity.

  1. Payment for egg donation and surrogacy. (United States)

    Steinbock, Bonnie


    This article examines the ethics of egg donation. It begins by looking at objections to noncommercial gamete donation, and then takes up criticism of commercial egg donation. After discussing arguments based on concern for offspring, inequality, commodification, exploitation of donors, and threats to the family, I conclude that some payment to donors is ethically acceptable. Donors should not be paid for their eggs, but rather they should be compensated for the burdens of egg retrieval. Making the distinction between compensation for burdens and payment for a product has the advantages of limiting payment, not distinguishing between donors on the basis of their traits, and ensuring that donors are paid regardless of the number or quality of eggs retrieved.

  2. Financial considerations in living organ donation. (United States)

    Jacobs, Cheryl; Thomas, Charlie


    The shortage of cadaveric organs and increased success of living donor transplantation support the use of living organ donors. Clinical social workers have the opportunity to explore a variety of donor-specific issues when performing psychosocial evaluations of living donors, including motivation, psychological stability, and personal and family consequences of donation, as well as the direct and indirect financial consequences faced by living donors. Although most donor-related medical costs are covered, other associated expenses are not reimbursable and may put donors at risk for financial hardship. Out-of-pocket expenses also serve as a disincentive to donate for some volunteers. During the evaluation process, healthcare professionals should openly discuss how surgery, recovery, and any potential complications might impact prospective donors' financial situation. Donors can then decide whether they are able to realistically handle the costs of donation. We present the financial dilemmas experienced by many living donors and highlight efforts that have been made to deal with them.

  4. Attitudes of intensive care and emergency physicians in Australia with regard to the organ donation process: A qualitative analysis. (United States)

    Macvean, Emily; Yuen, Eva Yn; Tooley, Gregory; Gardiner, Heather M; Knight, Tess


    Specialized hospital physicians have direct capacity to impact Australia's sub-optimal organ donation rates because of their responsibility to identify and facilitate donation opportunities. Australian physicians' attitudes toward this responsibility are examined. A total of 12 intensive care unit and three emergency department physicians were interviewed using a constructionist grounded theory and situational analysis approach. A major theme emerged, related to physicians' conflicts of interest in maintaining patients'/next-of-kin's best interests and a sense of duty-of-care in this context. Two sub-themes related to this main theme were identified as follows: (1) discussions about organ donation and who is best to carry these out and (2) determining whether organ donation is part of end-of-life care; including the avoidance of non-therapeutic ventilation; and some reluctance to follow clinical triggers in the emergency department. Overall, participants indicated strong support for organ donation but would not consider it part of end-of-life care, representing a major obstacle to the support of potential donation opportunities. Findings have implications for physician education and training. Continued efforts are needed to integrate the potential for organ donation into end-of-life care within intensive care units and emergency departments.

    The aim of this study is to explore healthcare professionals' perception of the influence of Islamic beliefs and traditions concerning organ donation and transplants in Algeria. Exploratory qualitative study using individual semi-structured interviews of 17 healthcare professionals (9 men, 8 women) of different specialties in a University hospital in Algiers (Algeria). Qualitative content analysis of transcripts was performed using the computer software ATLAS.ti 5. Healthcare professionals believe that religious beliefs do not affect living donation but say they have a negative impact on donation of cadaveric organs due to the existence of myths derived from the Islamic religion and lack of knowledge of the Algerian population about the positioning of religious leaders in relation to organ donation and transplantation. There is confusion among the Algerian population on the position of Islam around organ donation and transplantation, mainly to the detriment of the rate of cadaveric donation. Collaboration between the health sector and religious leaders to raise public awareness could improve the willingness of the population to donate organs after death. Copyright © 2016 SESPAS.

    Full Text Available Background: Hemovigilance like quality systems and audits have become an integral part of Blood Transfusion Services in the developed countries and has contributed greatly to its development. Hemovigilance begins with donors and must enable the collection of information on reactions occurring during the donation of blood, selections of donors and to prevent such incidents. The aim of study was to help identify the trends of adverse events , occurring in blood donors at a tertiary-care hospital, to recommend best practices to improve donor care and safety Materials and Methods: This record-based study was conducted on all adverse events related to allogenic whole blood donations performed over 24 months. All whole blood donations were analyzed. All adverse events occurring during or at the end of the donation were noted using a standardized format and analyzed determining significance at p<0.05. Results: Overall rate was 0.3% with vasovagal reactions constituting 82%, and 18% mild syncopal reactions (p<0.001. Immediate vasovagal reaction with injury was very rare (0.007%. Vasovagal reactions showed a significant association with young age, female gender, first time donation status. Mean age of persons recording adverse effects was 30.23 ± 7.49 years as compared to those without adverse effects, 31.14 ± 8.56 years. Conclusion: Donor safety is an essential perquisite to increase voluntary blood donation. AE analysis helps in identifying the blood donors at risk of AE, applying appropriate motivational strategies, predonation counseling, care during and after donation, developing guidelines and hemovigilance programme in countries with limited resources.

  7. Altruism or solidarity? The motives for organ donation and two proposals. (United States)

    Saunders, Ben


    Proposals for increasing organ donation are often rejected as incompatible with altruistic motivation on the part of donors. This paper questions, on conceptual grounds, whether most organ donors really are altruistic. If we distinguish between altruism and solidarity--a more restricted form of other-concern, limited to members of a particular group--then most organ donors exhibit solidarity, rather than altruism. If organ donation really must be altruistic, then we have reasons to worry about the motives of existing donors. However, I argue that altruism is not necessary, because organ donation supplies important goods, whatever the motivation, and we can reject certain dubious motivations, such as financial profit, without insisting on altruism. Once solidaristic donation is accepted, certain reforms for increasing donation rates seem permissible. This paper considers two proposals. Firstly, it has been suggested that registered donors should receive priority for transplants. While this proposal appears based on a solidaristic norm of reciprocity, it is argued that such a scheme would be undesirable, since non-donors may contribute to society in other ways. The second proposal is that donors should be able to direct their organs towards recipients that they feel solidarity with. This is often held to be inconsistent with altruistic motivation, but most donation is not entirely undirected in the first place (for instance, donor organs usually go to co-nationals). While allowing directed donation would create a number of practical problems, such as preventing discrimination, there appears to be no reason in principle to reject it. © 2012 Blackwell Publishing Ltd.

    Donations in Turkey are insufficient to cover the high transfusion needs arising from large numbers of thalassemia and sickle cell anemia patients and increasing demands for blood due to advanced surgery and cancer treatment. The most acceptable means to get blood is voluntary blood donation and the blood donor system in Turkey mostly depends on a combination of voluntary and involuntary donors. The main aim of this study is to explore the motivations of Turkish voluntary blood donors toward blood donation and to determine predictors of blood donation motivation. A cross-sectional sample survey of active blood donors in Ankara, Turkey was conducted. The sample consisted of 189 male volunteer blood donor adults. Donors filled in a self-administered questionnaire including the measures of demographic information, empathetic concern, altruism, social responsibility and blood donation motivation questionnaire during donation. Factor analysis of Blood Donation Motivation Measure with varimax rotation revealed a three-factor solution named as "values and moral duty", "positive feelings and esteem" and "self-benefit and external reasons". The results with regression analyses showed that only social responsibility had an significant effect independent of age, income, and education on blood donation motivation. These result reflects that blood donation motivation not only linked to a high degree of altruistic reasons, but also to a combination of some self-regarding motives. Additionally, feelings of empathy or altruism may be less strong at the time the decision to help, other factors may have a larger influence on helping decisions. Copyright © 2013 Elsevier Ltd.

  9. Communication prompts donation: exploring the beliefs underlying registration and discussion of the organ donation decision. (United States)

    Hyde, Melissa K; White, Katherine M


    To use a theory of planned behaviour (TPB) framework to explore the beliefs underlying communication of the donation decision for people who had not previously registered their consent on a donor register or discussed their decision with significant others. Initially, a focus group study elicited the common TPB (behavioural, normative, and control) beliefs about registering and discussing the organ donation decision. The main study assessed the important TPB belief predictors of intentions to register and discuss the donation decision.
