  3. Transfusion of blood and blood component therapy for postpartum haemorrhage at a tertiary referral center

    International Nuclear Information System (INIS)

    Objective: To determine the practice of transfusion of blood and blood products in cases of postpartum haemorrhage, at a tertiary referral center. Methods: A retrospective study was conducted where medical records were reviewed for women, who either delivered or were admitted in labour suite with diagnosis of postpartum haemorrhage. The study period extended from Jan 2008 to Oct 2009. During a period of 22 months, records were reviewed for transfusion of blood and blood products in above group of women. Data were analyzed for descriptive statistics. Results: During the study period, a total of 4744 patients were admitted in the labour suite. A total of 113 (2.36%) women were diagnosed with Post partum haemorrhage. Uterine atony was the commonest cause of PPH, followed by genital tract trauma. A total of 81(71%) women received transfusion of blood and blood components (1.6%). The mean blood loss was 1088 ml (+- 584ml). Transfusion of blood and blood component therapy was significantly more in women who underwent caesarean section, compared to those women who delivered vaginally. There was one case of acute tubular necrosis due to PPH, and seven maternal deaths. The mean hospital stay was of +- 3 days. Conclusion: In this hospital based study, the prevalence of PPH was 2.36 +- %, and the rate of transfusion of blood and blood products was 1.6%.

    Full Text Available Materials and Methods: The study was performed on prospective donors who reported to the Department of Transfusion Medicine. Individuals deferred due to hypertension contributed the study population. They were compared with age and sex matched donor controls. Demographic details were recorded in a proforma. On identification of a hypertensive individual, consequent two comparable donors were taken as controls with a total of 50 hypertensive subjects. Hypertensive status of the subjects were assessed based on the criteria formulated by the WHO-ISH and US Seventh Joint National Committee report on prevention, detection, evaluation and treatment of high blood pressure. Results: About 0.95% of healthy blood donors had undetected hypertension. Mean age at detection of hypertension in the study group was 35.44 ± 7.69 years. Higher BMI was observed in the hypertensive group compared to normotensive control group with P value significant at 0.0001. Conclusion: About 1% of healthy individuals were found to have undetected hypertension. Though the study was not designed to determine the prevalence of hypertension in the region, it is a rough estimate of the proportion of undetected hypertension in the local population as donors are considered as representative of healthy population.

    Full Text Available Background and Objective: The implementation of quality system and continuous evaluation of all activities of the Blood Transfusion Services (BTS can help to achieve the maximum quantity and quality of safe blood. Optimizing blood collection and processing would reduce the rate of discard and improve the efficiency of the BTS. The objective of this study is to determine the rate of discard of blood and blood component and identify its reasons at the National Blood Centre (NBC, Kuala Lumpur, during the year of 2007 in order to introduce appropriate intervention. Study Designs and Methods: Data on the number of discarded whole blood units and its components, reasons for discard, and the number of blood components processed as well as the number of collected blood units were obtained from the Blood Bank Information System - NBC database. These were analyzed. Results: The total number of blood units collected in 2007 was 171169 from which 390636 units of components were prepared. The total number of discarded whole blood units and its components was 8968 (2.3%. Platelet concentrate recorded the highest of discard at 6% (3909 followed by whole blood at 3.7% (647, fresh frozen plasma (FFP at 2.5% (2839, and cryoprecipitate at 2% (620. The rate of discarded packed red blood cells RBCs, plasma aphaeresis, and PLT aphaeresis was less than 1% at 0.6% (902, 0.6% (37, and 0.29% (14, respectively. RBC contamination of PLT and plasma were the major cause of discard at 40% (3558. Other causes include leakage (26% - 2306, lipemia (25% - 2208, and underweight (4% - 353. Conclusion: Good donor selection, training and evaluation of the staff, as well as implementation of automation will help to improve processes and output of BTS. This would reduce discard of blood components and wastage caused by non conformance.

    Full Text Available   Stem cells are naïve or master cells. This means they can transform into special 200 cell types as needed by body, and each of these cells has just one function. Stem cells are found in many parts of the human body, although some sources have richer concentrations than others. Some excellent sources of stem cells, such as bone marrow, peripheral blood, cord blood, other tissue stem cells and human embryos, which last one are controversial and their use can be illegal in some countries. Cord blood is a sample of blood taken from a newborn baby's umbilical cord. It is a rich source of stem cells, umbilical cord blood and tissue are collected from material that normally has no use following a child’s birth. Umbilical cord blood and tissue cells are rich sources of stem cells, which have been used in the treatment of over 80 diseases including leukemia, lymphoma and anemia as bone marrow stem cell potency.  The most common disease category has been leukemia. The next largest group is inherited diseases. Patients with lymphoma, myelodysplasia and severe aplastic anemia have also been successfully transplanted with cord blood. Cord blood is obtained by syringing out the placenta through the umbilical cord at the time of childbirth, after the cord has been detached from the newborn. Collecting stem cells from umbilical blood and tissue is ethical, pain-free, safe and simple. When they are needed to treat your child later in life, there will be no rejection or incompatibility issues, as the procedure will be using their own cells. In contrast, stem cells from donors do have these potential problems. By consider about cord blood potency, cord blood banks (familial or public were established. In IRAN, four cord blood banks has activity, Shariati BMT center cord blood bank, Royan familial cord blood banks, Royan public cord blood banks and Iranian Blood Transfusion Organ cord blood banks. Despite 50,000 sample which storage in these banks, but the

    1992-06-01

    A study of risk factors for hepatitis B carriers among voluntary blood donors of the National Blood Center, Thai Red Cross Society was carried out in a case-control study design during January 1989 to June 1990. Cases were 876 blood donors whose blood identified HBsAg at time of recruitment and continued positive for more than 6 months. Controls were 1,750 blood donors whose blood was free from HBsAg who came for blood donation at the same period as the cases. The ratio of cases:controls = 1:2. Self-administered questionnaires were constructed and pretested before using both cases and controls. The study revealed that the risk factors for hepatitis B among voluntary blood donors were age of less than 30 years old; low socioeconomic status (family income of less than 8,000 Baht/month); single status, especially males; male occupations of students, monks, nongovernment workers compared with government officials; female occupations of laborers, students, nongovernment workers and government officials compared with housewives. Sharing of nail clippers, used blades and tooth brushes among family members are proved to be risk factors, especially among males. In addition, sharing of used blades in barber shops proved to be a risk among males while sharing of nail clippers in beauty salons, history of ear-piercing at department stores or history of caesarean section among females could not be shown to be risk factors.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:1439976

    Full Text Available Artificial blood is a product made to act as a substitute for red blood cells. While true blood serves many different functions, artificial blood is designed for the sole purpose of transporting oxygen and carbon dioxide throughout the body. Depending on the type of artificial blood, it can be produced in different ways using synthetic production, chemical isolation, or recombinant biochemical technology. Development of the first blood substitutes dates back to the early 1600s, and the search for the ideal blood substitute continues. Various manufacturers have products in clinical trials; however, no truly safe and effective artificial blood product is currently marketed. It is anticipated that when an artificial blood product is available, it will have annual sales of over $7.6 billion in the United States alone.

A total of 8 685 samples of voluntary blood donors were tested on Trepolisa 3.0 and then the initially reactive samples were retested in duplicate on the same assay as well as on Omega Pathozyme, RPR, RAPHA (Rapid Anti-Treponema pallidum Assay, and TPHA. Of the 158 initially reactive samples, 104 were repeatedly reactive on the same assay, 85 were reactive with RPR, 77 were reactive with RAPHA, 60 were reactive on Omega, and 53 were confirmed reactive on TPHA. 48 (56.4% of the results on RPR were biological false positive, while 21.9% of results were false negative on RPR. We evaluated that Omega Pathozyme was quite in agreement with TPHA as compared with Trepolisa 3.0, RAPHA, and RPR. We concluded that Omega Pathozyme (ELISA can be considered as a suitable test for screening of syphilis in a blood center.

    Kasraian, Leila; Karimi, Mohammad Hossein

    2016-01-01

    Background: Confidential unit exclusion (CUE) system has been designed to enhance transfusion safety as an extra additive approach. Aims: This study was designed to survey demographic characteristics, prevalence of serologic markers, and reasons of opting CUE. Materials and Methods: The cross-sectional study was performed at Shiraz Blood Transfusion Center (Southern Iran). CUE is used for all individuals who refer for blood donation, and donors can choose their blood not to be used if they have any doubt about their blood suitability for transfusion. The prevalence rate of HIV, hepatitis B virus (HBV), and hepatitis C virus (HCV) was compared between the blood donors who opted into and out of CUE. Then, the donors were contacted to give another blood sample and the reasons of deferral. Researchers also determined whether their reasons were logical or not. Data were analyzed using comparison of proportions in MedCalc software 7. Results: Out of all the donors, 2365 ones (2.3%) opted for CUE. CUE was more frequent among men, singles, donors with low education levels, between 18 and 25 years old, and with history of previous donation (P 0.05). Furthermore, 91.5% of the donors had opted for CUE by mistake and only 8% had chosen CUE logically. Conclusion: It is necessary to review the process of CUE, make some changes both in procedure and design, and then survey its effectiveness in blood safety.

    Full Text Available Abstract Background In China, high prevalence of HBV and HCV parallels with the growing epidemic of syphilis and HIV in the general population poses a great threat to blood safety. This study investigated the prevalence of serologic markers for transfusion transmissible infections (TTIs among four Chinese blood centers. Methods We examined whole blood donations collected from January 2000 through December 2010 at four Chinese blood centers. Post-donation testing of TTIs (HIV, HBV, HCV and syphilis were conducted using two different enzyme-linked immunosorbent assay kits for each seromarker. The prevalence of serologic markers for TTIs (% was calculated and additional analysis was conducted to examine donor characteristics associated with positive TTIs serology. Results Of the 4,366,283 donations, 60% were from first-time donors and 40% were from repeated donors. The overall prevalence of HIV, HBsAg, HCV and syphilis was 0.08%, 0.86%, 0.51% and 0.47%, respectively. The prevalence profile of TTIs varied among different blood centers and appeared at relatively high levels. Overall, the prevalence of HBsAg and HCV demonstrated a decline trend among four blood centers, while the prevalence of HIV and syphilis displayed three different trends: constantly steady, continually increasing and declining among different centers. Conclusions This study reflects the risk of TTIs has been greatly reduced in China, but blood transfusion remains an ongoing risk factor for the spread of blood-borne infections, and further work and improvements are needed to strengthen both safety and availability of blood in China.

    2010-01-01

    Full Text Available Introduction: Deferrals lead to loss of precious whole blood donors (WBD and blood units available for transfusion purposes. Knowledge of rate and causes of donor deferral can guide the recruitment strategy for WBD. Aim: To find the incidence and causes of deferral in Indian WBD and apply relevant findings to modify recruitment strategy for blood donors. Materials and Methods: Data for WBD presenting for donation in a blood center and outdoor camps over one and half year were analyzed retrospectively. National guidelines were used for selection and deferral of WBD. Result: 736 (11.6% WBD were deferred out of 6357 presenting for donation during the study period. Most (69.8% of the donors were deferred on physical examination and hemoglobin (Hb testing. Most common reasons for deferral were low Hb (55.8%, abnormal blood pressure (11.1%, medication (6.9% and underweight donors (2.9%. Significantly more volunteers were deferred than relative donors (13.97% vs 5.80%; P<0.000. Females were found to have higher deferral rate than males (53.5% vs 6.9%; P=0.000 and higher odds ratio for deferral (15.4. Donors older than 40 years of age had significantly higher chance of being deferred (P<0.05. Discussion and Conclusion: It is important to determine the rate and causes of WBD deferral to guide the recruitment and retention efforts at local, regional, and national level.

    Full Text Available Background: Blood culture is the criterion standard for identifying children with bacteremia. However, elevated false-positive rates are common and are associated with substantial health care costs. The aims of this prospective study were to: 1 determine the rate of blood culture contamination 2 determine variety and frequency of contaminant bacteria 3 compare the duration of hospital stay and antibiotic administration in patients with true bacteremia vs those have false positive blood culture. Materials and Methods: Cross-sectional study conducted April through July 2004 among patients aged 14 years or younger who were admitted at Doctor Garib Children Medical Center of Tehran and had a blood culture obtained as part of their care. Bacterial isolates were identified to species level and medical records were reviewed in all cases with a positive blood culture. A number of clinical and laboratory criteria were used to deciding whether a blood isolate is a pathogen or a contaminant. These include the identify of the micro-organism itself, clinical features such as fever and leukocytosis; the proportion of blood culture sets positive as a function of the number of sets obtained and to have an indwelling vascular catheter or prosthetic device. Results: During the study period, 2877 sets of blood culture were evaluated and the rates of positive blood cultures associated with significant bacteremia and contamination were 1.04% and 5.4% respectively. Among the positive blood cultures, over the 84% of isolates were due to contamination and only 15.95% of isolated strains associated with true infection. The frequency of isolated bacteria with respect to true infection and contamination are as following: S. Aureus (infect: 9.0%, contam: 0.0%, S. Epidemidis (infec: 0.0%, contam: 13.3%, Micrococcus sp. (infec: 0.0%, contam: 4.3%, pseudomonas and related species other than P. aeruginosa (infec: 2.1%, contam: 60.6%, viridans group of streptococci (infec: 1

    The immunohistochemical distribution of 15 blood coagulation factors in the germinal centers (GCs) of human Peyer's patches (PPs) was studied. Although factor VIII, active alpha-thrombin, and fibrinogen were hardly evident in the GCs, the majority of coagulation factors, such as kallikrein, high-molecular-weight kininogen, factos XII, X, IX, VII, V, XIIIa and XIIIb, prothrombin, anti-thrombin 111 and inactive alpha-thrombin were found, showing a lace-like s...

    A new approach to the analysis of the blood beryllium lymphocyte proliferation test (LPT) was presented to the Committee to Accredit Beryllium Sensitization Testing-Beryllium Industry Scientific Advisory Committee in April, 1994. Two new outlier resistant methods were proposed for the analysis of the blood LPT and compared with the approach then in use by most labs. The National Jewish Center (NJC) agreed to provide data from a study that was underway at that time. Three groups of LPT data are considered: (1) a sample of 168 beryllium exposed (BE) workers and 20 nonexposed (NE) persons; (2) 25 unacceptable LPTs, and (3) 32 abnormal LPTs for individuals known to have chronic beryllium disease (CBD). The LAV method described in ORNL-6818 was applied to each LPT. Graphical and numerical summaries similar to those presented for the ORISE data are given. Three methods were used to identify abnormal LPTs. All three methods correctly identified the 32 known CBD cases as abnormal.

  11. Response to post-donation counseling is still a challenge in outdoor voluntary blood donation camps: A survey from a tertiary care regional blood center in Eastern India

    Directory of Open Access Journals (Sweden)

    Somnath Mukherjee

    2014-01-01

    Full Text Available Background: Blood transfusion carries the risk of transmission of several infectious agents. The latest method for blood screening, nucleic acid testing is not affordable in developing countries. Aim: The study was aimed to find response to post-donation counseling for reactive markers among the voluntary blood donors donating in blood donation camps. Material and Methods: This 1 year study was conducted in 2011. Transfusion transmitted infections testing was performed by routine enzyme linked immunosorbent assay method. The initial human immunodeficiency virus (HIV reactive donors who returned back to the blood bank were confidentially counseled and referred to the Integrated Counseling Cum Testing Center (ICTC. The hepatitis B surface antigen (HBsAg and anti-hepatitis C virus (HCV reactive donors were referred to the gastroenterology department for confirmation by qualitative polymerase chain reaction (PCR, Roche Diagnostics, Germany and followed-up. Results: Twenty seven thousand two hundred forty six 27,246 units were collected during the survey. One hundred twenty nine129 units were reactive for HIV 1 and 2, 99 were reactive for HCV, 206 for hepatitis B virus (HBV. Of these reactive donors, 138 could be personally communicated. Out of 47, 27 donors who returned for counseling were initially reactive for HIV 1 and 2, 8 for HBsAg and 12 for anti-HCV. Two were positive for HBV deoxyribonucleic acid and one was positive for HCV ribonucleic acid. The HIV positivity was detected in 1 of 27 donors at ICTC. Conclusion: The response to the post-donation counseling appears in this study to be only 34% (47/138, which is still a challenge.

  15. Prevalence of human T-cell lymphotropic virus types 1 and 2 in blood donors of the Caruaru Blood Center (Hemope

    Directory of Open Access Journals (Sweden)

    Waleska Mayara Gomes de Lima

    2013-01-01

    Full Text Available BACKGROUND: There is difficulty in gathering data on the prevalence of human T-cell lymphotropic virus in blood donors as confirmatory testing is not mandatory in Brazil. This suggests there may be an underreporting of the prevalence. OBJECTIVE: To estimate the prevalence of human T-cell lymphotropic virus types 1 and 2 in donors of a blood bank in Caruaru, Brazil. METHODS: This was an observational, epidemiological, descriptive, longitudinal and retrospective study with information about the serology of donors of the Caruaru Blood Center, Fundação de Hematologia e Hemoterapia de Pernambuco (Hemope from May 2006 to December 2010. The data were analyzed using the Excel 2010 computer program (Microsoft Office(r. RESULTS: Of 61,881 donors, 60 (0.096% individuals were identified as potential carriers of human T-cell lymphotropic virus types 1 and 2. Of these, 28 (0.045% were positive and 32 (0.051% had inconclusive results in the serological screening. Forty-five (0.072% were retested; 17 were positive (0.027% and 3 inconclusive (0.005%. After confirmatory tests, 8 were positive (0.013%. Six (75% of the confirmed cases were women. CONCLUSION: Epidemiological surveys like this are very important in order to create campaigns to attract donors and reduce the costs of laboratory tests.

  12. Progression of Blood Pressure and Cardiovascular Outcomes in Hypertensive Patients in a Reference Center

    International Nuclear Information System (INIS)

    Hypertension is a public health problem, considering its high prevalence, low control rate and cardiovascular complications. Evaluate the control of blood pressure (BP) and cardiovascular outcomes in patients enrolled at the Reference Center for Hypertension and Diabetes, located in a medium-sized city in the Midwest Region of Brazil. Population-based study comparing patients enrolled in the service at the time of their admission and after an average follow-up of five years. Participants were aged ≥18 years and were regularly monitored at the Center up to 6 months before data collection. We assessed demographic variables, BP, body mass index, risk factors, and cardiovascular outcomes. We studied 1,298 individuals, predominantly women (60.9%), and with mean age of 56.7±13.1 years. Over time, there was a significant increase in physical inactivity, alcohol consumption, diabetes, dyslipidemia, and excessive weight. As for cardiovascular outcomes, we observed an increase in stroke and myocardial revascularization, and a lower frequency of chronic renal failure. During follow-up, there was significant improvement in the rate of BP control (from 29.6% to 39.6%; p = 0.001) and 72 deaths, 91.7% of which were due to cardiovascular diseases. Despite considerable improvements in the rate of BP control during follow-up, risk factors worsened and cardiovascular outcomes increased

  14. Post Mortem Blood and Vitreous Humor Ethanol Levels Relation in Fars Legal Medicine Center

    Directory of Open Access Journals (Sweden)

    Aria Hejazi

    2012-11-01

    Full Text Available Background and Objective: The concentration of ethanol measured in postmortem blood needs to be interpreted as to whether the person who had consumed alcohol has exceeded some threshold limit. However, interpreting postmortem BAC (Blood Alcohol Concentration results and drawing correct conclusions about ante mortem levels is fraught with difficulties as under some circumstances alcohol might be produced after death by microbial activity.Subjects and Methods: In the case of ethanol, the blood samples should be taken from a femoral vein and whenever possible additional specimens, such as urine and vitreous humor (VH, should also be obtained and sent for analysis to be able to have the best interpretationResults: 167 Specimens of femoral vein blood and vitreous humor were analyzed. In this study, direct injection and gas-chromatographic techniques were employed to quantitate the ethanol concentrations. These two concentrations were then compared and the BAC/VHAC (Viterous Humor Alcohol Concentration ratio was evaluated.Among these specimens, there were 142 cases in which we have found ethanol in blood but not in vitreous humor. Also we have found 2 cases by positive VHAC but negative BAC. The average blood ethanol concentration was 61.5 mg/dLit while the average ethanol vitreous humor concentration was 127 mg/dLit. However, the ratio was measured as 0.7.Conclusion: The similarity in the results of the post mortem cases reinforces the assertion that co analysis of vitreous humor and blood is important to interpret post mortem results

  15. Risk factors for deferral due to low hematocrit and iron depletion among prospective blood donors in a Brazilian center

    Directory of Open Access Journals (Sweden)

    Eloísa Tedeschi Dauar

    2015-10-01

    Full Text Available OBJECTIVE: Deferral of blood donors due to low hematocrit and iron depletion is commonly reported in blood banks worldwide. This study evaluated the risk factors for low hematocrit and iron depletion among prospective blood donors in a large Brazilian blood center.METHOD: A case-control study of 400 deferred donors due to low hematocrit and 456 eligible whole blood donors was conducted between 2009 and 2011. Participants were interviewed about selected risk factors for anemia, and additional laboratory tests, including serum ferritin, were performed. Bivariate and multivariate analyses were performed to assess the association between predictors and deferral due to low hematocrit in the studied population and iron depletion in women.RESULTS: Donors taking aspirins or iron supplementation, those who reported stomachache, black tarry stools or hematochezia, and women having more than one menstrual period/month were more likely to be deferred. Risk factors for iron depletion were repeat donation and being deferred at the hematocrit screening. Smoking and lack of menstruation were protective against iron depletion.CONCLUSION: This study found some unusual risk factors related to gastrointestinal losses that were associated with deferral of donors due to low hematocrit. Knowledge of the risk factors can help blood banks design algorithms to improve donor notification and referral.

    We decided to determine the percentage of hypertensive patients whose blood pressure (BP) measurements were within recommended controlled range and to identify predictive factors for controlled BP. In this study carried out in 2014, 280 patients were included consecutively through sampling from both university and private medical centers/pharmacies in four Iranian cities. Demographic data as well as information about duration of HTN and prescribed medications, admission to emergency department (ED) because of HTN crisis, comorbidities, and control of HTN during the last 6 months by a healthcare provider were gathered. Adherence to anti-hypertensives was also determined using the validated Persian version of the 8-item Morisky Medication Adherence Scale (MMAS-8). Controlled BP was defined as systolic BPpersonnel (adjusted OR= 1.03, P= 0.04), and not having history of ED admission during the last 6 months because of HTN crisis (adjusted OR= 2.11, P= 0.01). Considerable number of the studied patients had uncontrolled BP. Regarding the dramatic consequences of uncontrolled high BP in long term, it is advisable that careful attention by health care providers to the aforementioned factors could raise the likelihood of achieving controlled BP.

    Blood blister-like aneurysms (BBAs) are a controversial entity. They arise from non-branching sites on the supraclinoid internal carotid artery (ICA) and are suspected to originate from a dissection. Our aim is to describe the BBA cases seen in our center and to present a systematic review of the literature on BBAs. We analyzed the eleven cases of BBA admitted to our center from 2003 to 2012. We assessed the medical history, treatment modality (endovascular and/or surgery), complications and clinical outcome. The cohort included 8 women and 4 men with a mean age of 53.16 years. Treatment of the BBA consisted of stenting and coiling in 5 patients, stenting only in 4 patients, coiling and clipping in 1 patient, clipping only in 1 patient, and conservative treatment in 1 patient. A good outcome was found in 10 patients, as defined by a modified Rankin Scale (mRS) less than or equal to two at three months. A systematic review of the literature was performed, and 314 reported patients were found: 221 patients were treated with a primarily surgical approach, and 87 patients were treated with a primarily endovascular approach. A rescue or second treatment was required in 46 patients (21%). The overall estimated treatment morbidity rate was 17%, and the mortality rate was 15%. BBAs exhibit more aggressive behavior compared to saccular aneurysms, and more intra-operative complications occur with BBAs, independent of the treatment type offered. They are also significantly more likely to relapse and rebleed after treatment. Endovascular treatment offers a lower morbidity–mortality compared with surgical approaches. Multilayer flow-diverting stents appear to be a promising strategy.

    There is an expectation that the blood will always be there when it is really needed. Blood donor volunteers constitute the main supply source in an effective blood supply chain management. They feed blood stocks through their donation. In an emergency situation, if the stocks are insufficient, the only source of blood supply will be the people who come to the health center and donate the blood on a voluntary basis. It is certain that time is a very important component in such ...

  1. [Blood donation in urban areas].

    Science.gov (United States)

    Charpentier, F

    2013-05-01

    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. PMID:23597586

    2014-01-01

    We did a subject-level meta-analysis of the changes (Δ) in blood pressure (BP) observed 3 and 6 months after renal denervation (RDN) at 10 European centers. Recruited patients (n=109; 46.8% women; mean age 58.2 years) had essential hypertension confirmed by ambulatory BP. From baseline to 6 months, treatment score declined slightly from 4.7 to 4.4 drugs per day. Systolic/diastolic BP fell by 17.6/7.1 mm Hg for office BP, and by 5.9/3.5, 6.2/3.4, and 4.4/2.5 mm Hg for 24-h, daytime and nighttime BP (P⩽0.03 for all). In 47 patients with 3- and 6-month ambulatory measurements, systolic BP did not change between these two time points (P⩾0.08). Normalization was a systolic BP of <140 mm Hg on office measurement or <130 mm Hg on 24-h monitoring and improvement was a fall of ⩾10 mm Hg, irrespective of measurement technique. For office BP, at 6 months, normalization, improvement or no decrease occurred in 22.9, 59.6 and 22.9% of patients, respectively; for 24-h BP, these proportions were 14.7, 31.2 and 34.9%, respectively. Higher baseline BP predicted greater BP fall at follow-up; higher baseline serum creatinine was associated with lower probability of improvement of 24-h BP (odds ratio for 20-μmol l−1 increase, 0.60; P=0.05) and higher probability of experiencing no BP decrease (OR, 1.66; P=0.01). In conclusion, BP responses to RDN include regression-to-the-mean and remain to be consolidated in randomized trials based on ambulatory BP monitoring. For now, RDN should remain the last resort in patients in whom all other ways to control BP failed, and it must be cautiously used in patients with renal impairment. PMID:24067345

    Human blood has been transfused for about 60-70 years. Over this time, the practice of blood transfusion has changed dramatically. One major change is the separation of blood into its various components. As a result, the patient can receive only the blood component in which he is deficient. In this way, the risk of side effects—particularly hepatitis—is lessened. This article briefly reviews the various blood products, the indications for their use, and some associated risks.

    Full Text Available This paper is focused on Blood Donation Management System which is a web application with supporting mobile application aimed to serve as a communication tool between patients (who need blood and blood donor. To become members of the system, donors need to create their profiles by providing fundamental information like name, blood group, email address, password, and exact location from “Google Map”. In order to find out the exact location of a donor, Google Map is integrated with this application. The mobile application always updates the location of a donor. As a result, the system can automatically find a registered donor wherever he/she goes. Visitors can search blood donors from the home page by blood group and the place where blood is needed. The system will show the available donors along with their phone number, email address and mailing address through arranging them by nearest place and blood donation expire date. Visitors can send message to all donors through email but a member can send message using email and mobile phone. An appointment will be created only whenever a donor confirms that he/she will donate blood. Then the system will alert the donor before 12 hours of donation. Blood donors can also be searched from the mobile application, but this is only accessible for registered members. The goal of this paper is to reduce the complexity of the system to find blood donors in an emergency situation.

    It is sometimes necessary for the practitioner to transfuse the ruminant with whole blood or plasma. These techniques are often difficult to perform in practice, are time-consuming, expensive, and stressful to the animal. Acute loss of 20% to 25% of the blood volume will result in marked clinical signs of anemia, including tachycardia and maniacal behavior. The PCV is only a useful tool with which to monitor acute blood loss after intravascular equilibration with other fluid compartments has occurred. An acutely developing PCV of 15% or less may require transfusion. Chronic anemia with PCV of 7% to 12% can be tolerated without transfusion if the animal is not stressed and no further decline in erythrocyte mass occurs. Seventy-five percent of transfused bovine erythrocytes are destroyed within 48 hours of transfusion. A transfusion rate of 10 to 20 mL/kg recipient weight is necessary to result in any appreciable increase in PCV. A nonpregnant donor can contribute 10 to 15 mL of blood/kg body weight at 2- to 4-week intervals. Sodium citrate is an effective anticoagulant, but acid citrate dextrose should be used if blood is to be stored for more than a few hours. Blood should not be stored more than 2 weeks prior to administration. Heparin is an unsuitable anticoagulant because the quantity of heparin required for clot-free blood collection will lead to coagulation defects in the recipient. Blood cross-matching is only rarely performed in the ruminant. In field situations, it is advisable to inject 200 mL of donor blood into the adult recipient and wait 10 minutes. If no reaction occurs, the rest of the blood can probably be safely administered as long as volume overload problems do not develop. Adverse reactions are most commonly seen in very young animals or pregnant cattle. Signs of blood or plasma transfusion reaction include hiccoughing, tachycardia, tachypnea, sweating, muscle tremors, pruritus, salivation, cough, dyspnea, fever, lacrimation, hematuria

  1. SEROPREVALENCE OF CHAGASIC INFECTION IN YOUNG INDIVIDUALS IN A BLOOD CENTER IN THE STATE OF SAO PAULO, BRAZIL

    Directory of Open Access Journals (Sweden)

    Elaine Cristina Navarro

    2013-07-01

    Full Text Available SUMMARY This study aimed at estimating the number of cases of non-negative serological reactions to Chagas disease in blood donors at the Blood Center of Botucatu, São Paulo, Brazil, from 2003 to 2010 and at relating them to their cities of origin. Five hundred and seventy-four non-negative results for Chagas disease were evaluated. Of these, 371 (64.8% were reagent, and 203 (35.4% were inconclusive. The prevalence of Chagas disease in blood donors was 0.05%. There were, on average, 72 cases/year, and a prevalence of males was observed (64.8%. Forty-three (7.49% individuals were 18 to 30 years old; 92 (16.02% were 31 to 40; 147 (25.61% 41 to 50, and 292 (50.87% were older than 50 years. It was observed that 29.3% of females with reagent serology were at their fertile age (18 and 45 years. The majority of donors were originally from cities in the southwestern and central regions of São Paulo, but individuals from other states contributed with 20%. The provenance of most donors was the city of Botucatu/SP, followed by the city of Taquarituba/SP. Therefore, the profile of donors at this blood center favors the occurrence of a larger number of non-negative serological reactions. Although there has been a significant reduction in the number of new cases/year for this disease, it is still a public-health problem, and results suggest the need for new epidemiological assessments in the studied region.

  3. AN ANDROID APPLICATION FOR VOLUNTEER BLOOD DONORS

    Directory of Open Access Journals (Sweden)

    Sultan Turhan

    2015-05-01

    Full Text Available There is an expectation that the blood will always be there when it is really needed. Blood donor volunteers constitute the main supply source in an effective blood supply chain management. They feed blood stocks through their donation. In an emergency situation, if the stocks are insufficient, the only source of blood supply will be the people who come to the health center and donate the blood on a voluntary basis. It is certain that time is a very important component in such situation. For this reason, the health care center should call the nearest available donor in order to ensure to get the service as quickly as possible. A smart phone application is developed to facilitate the identification of the nearest available blood donor volunteer and the communication with him/her in the emergency situations where the blood can’t be supplied through the blood banks’ stocks. In this paper this application will be presented.

  4. Model 1: Blood

    International Nuclear Information System (INIS)

    Because most radiopharmaceuticals are introduced into the body via the vascular system and may remain in the circulation for prolonged periods of time, it is useful to have a model of the blood as an aid in the estimation of radiation dose. It is extremely difficult to devise a precise blood model; the geometry is complex and distribution of blood may vary with position, physiological state and disease process. Estimates of blood volume distribution vary among investigators. Furthermore, the regional hematocrit varies throughout the body, thus affecting distribution of the labeled material according to whether it is attached to cellular elements or in the plasma. The size of the blood pool volumes range from the heart to the capillaries. Variable amounts of non-penetrating radiation contributions to organs depend on the volume of blood in the various sized vessels and the energy of the electrons which may penetrate into tissue from the blood vessel. The present model represents an advance in that it takes into account to some extent the distribution of significant blood pools in the body. Further refinement of the macro-geometry is possible with data which can now be obtained from modern radionuclide imaging equipment. A more difficult problem is definging the micro-geometry relative to the distribution of blood in capillaries and sinusoids, and their relationship to one another

  14. Virtual blood bank

    Directory of Open Access Journals (Sweden)

    Kit Fai Wong

    2011-01-01

    Full Text Available Virtual blood bank is the computer-controlled, electronically linked information management system that allows online ordering and real-time, remote delivery of blood for transfusion. It connects the site of testing to the point of care at a remote site in a real-time fashion with networked computers thus maintaining the integrity of immunohematology test results. It has taken the advantages of information and communication technologies to ensure the accuracy of patient, specimen and blood component identification and to enhance personnel traceability and system security. The built-in logics and process constraints in the design of the virtual blood bank can guide the selection of appropriate blood and minimize transfusion risk. The quality of blood inventory is ascertained and monitored, and an audit trail for critical procedures in the transfusion process is provided by the paperless system. Thus, the virtual blood bank can help ensure that the right patient receives the right amount of the right blood component at the right time.

  5. Spatial relationships between lead sources and children's blood lead levels in the urban center of Indianapolis (USA).

    Morrison, Deborah; Lin, Qing; Wiehe, Sarah; Liu, Gilbert; Rosenman, Marc; Fuller, Trevor; Wang, Jane; Filippelli, Gabriel

    2013-04-01

    Urban children remain disproportionately at risk of having higher blood lead levels than their suburban counterparts. The Westside Cooperative Organization (WESCO), located in Marion County, Indianapolis, Indiana, has a history of children with high blood lead levels as well as high soil lead (Pb) values. This study aims at determining the spatial relationship between soil Pb sources and children's blood lead levels. Soils have been identified as a source of chronic Pb exposure to children, but the spatial scale of the source-recipient relationship is not well characterized. Neighborhood-wide analysis of soil Pb distribution along with a furnace filter technique for sampling interior Pb accumulation for selected homes (n = 7) in the WESCO community was performed. Blood lead levels for children aged 0-5 years during the period 1999-2008 were collected. The study population's mean blood lead levels were higher than national averages across all ages, race, and gender. Non-Hispanic blacks and those individuals in the Wishard advantage program had the highest proportion of elevated blood lead levels. The results show that while there is not a direct relationship between soil Pb and children's blood lead levels at a spatial scale of ~100 m, resuspension of locally sourced soil is occurring based on the interior Pb accumulation. County-wide, the largest predictor of elevated blood lead levels is the location within the urban core. Variation in soil Pb and blood lead levels on the community level is high and not predicted by housing stock age or income. Race is a strong predictor for blood lead levels in the WESCO community.

    Full Text Available Transfusion medicine has been constantly evolving through the years with improved technologies that enhance the capability of identifying existing and newer emerging transfusion transmissible infections (TTI. In spite of the efforts made by blood banks the risk of TTI remains. This article deals with the various steps involved in ensuring blood safety, i.e. donor selection, role of screening donated blood for known and emerging infections, issues and assessment of threat posed by the risk, methodologies employed for testing and possible suggestions to improve transfusion services. While the threat of TTI remains, with a concerted effort of private and government organisations, and co-operation from the diagnostic companies, it is possible to raise the levels of blood safety. A surveillance system is also essential to identify any new agents that might pose a threat in a geographic area and to include them too in the screening process.

    Influenza viruses, including highly pathogenic avian influenza virus (H5N1), could threaten blood safety. We analyzed 10,272 blood donor samples with a minipool nucleic acid amplication technique. Analytical sensitivity of the method was 804 geq/mL and 444 geq/mL for generic influenza primers and influenza (H5N1) subtype–specific primers. This study demonstrates that such screening for influenza viruses is feasible.

    Full Text Available Blood quantum, the measurement of American Indian ancestry possessed by members of America’s Indigenous nations, is most often considered a rubric utilized by the federal government in an oppressive form, or by tribal nations themselves as standards of tribal citizenship requirements. In this essay, the authors recontextualize blood as a medium of national identity within the context of the Cherokee Nation of Oklahoma. Such decentering, as presented here, illuminates Cherokee nationhood in ways that have significant political import.

  8. Fully portable blood irradiator

    International Nuclear Information System (INIS)

    A fully portable blood irradiator was developed using the beta emitter thulium-170 as the radiation source and vitreous carbon as the body of the irradiator, matrix for isotope encapsulation, and blood interface material. These units were placed in exteriorized arteriovenous shunts in goats, sheep, and dogs and the effects on circulating lymphocytes and on skin allograft retention times measured. The present work extends these studies by establishing baseline data for skin graft rejection times in untreated animals

    Blood comprises the largest version of the human proteome1. Changes of plasma protein profiles can reflect physiological or pathological conditions associated with many human diseases, making blood the most important fluid for clinical diagnostics2-4. Nevertheless, only a handful of plasma proteins are utilized in routine clinical tests. This is due to a host of reasons, including the intrinsic complexity of the plasma proteome1, the heterogeneity of human diseases and the fast kinetics assoc...

    2001-01-01

    A total of 2793 requisition forms received by the blood banks of a Service zonal hospital, between June 1995 and December 1999, were analysed. 1697 (60.71%) forms were demand for single unit blood. Blood was collected against only 1099 forms (39.34%) out of which 713 (64.88%) were single unit issue. Urgency of requirement and blood group of patients was omitted in 56% cases. 104 forms were received without mention of the indications for transfusion. History of previous transfusion and pregnancy/HDN were omitted in 25.1% and 37.38% cases respectively. At an average 14.61% of the total collection was discarded. Of the 292 units discarded, 242 units were due to non utilisation. A transfusion committee should be established in all hospitals with a licensed blood bank. It should constitute definite objectives and conduct regular audits (prospective audit, concurrent review or retrospective review), in order to achieve utmost efficiency and numerous benefits, in terms of workload, cost, errors, risks of transfusion and ultimately increased customer satisfaction. It should strive to abolish single unit and inappropriate transfusion, and advocate autologous transfusion. PMID:27365575

  2. Effect of antifibrinolytic drugs on transfusion requirement and blood loss during orthotopic liver transplantation: Results from a single center

    Directory of Open Access Journals (Sweden)

    Devi A

    2008-01-01

    Full Text Available Background: During orthotopic liver transplantation (OLT, activation of the fibrinolytic system can contribute significantly to perioperative bleeding. Prophylactic administration of antifibrinolytic agents has been shown to reduce blood loss and the need for allogenic transfusion. Objective: To study the effect of antifibrinolytics on requirement of blood components, blood loss and operative time during OLT in patients with end stage liver disease, reporting to a single centre. Materials and Methods: Consecutive patients who underwent OLT at this centre during the period February 2003-October 2007 were the subjects of this study. Based on the individual anesthesiologist′s preference, patients were assigned to receive either two million units of aprotinin (AP as a bolus followed by 5,00,000 units/hour or 10 mg/kg tranexamic acid (TAas a bolus followed by 10 mg/kg every six to eight hours, administered from the induction till the end of the surgery. Transfusion policy was standardized in all patients. Intraoperative red cell salvage was done wherever possible. The effect of these two antifibrinolytic drugs on transfusion requirement was evaluated as a whole and in a sub group of patients from each treatment group and compared with a concurrent control group that did not receive antifibrinolytic drugs. Results: Fifty patients (40 M / 10 F, 44 adults, 6 pediatric patients underwent OLT in the study period. Fourteen patients were given AP, 25 patients were given TA and 11 patients did not receive any of the agents(control group. The median volume of total blood components transfused in antifibrinolytic group (n=39 was 4540 ml(0-19,200ml, blood loss 5 l(0.7-35l and operative time 9h (4.5-17h and that of control group(n=11 was 5700 ml(0-15,500ml, 10 l(0.6-25 l and 9h (6.4-15.8h respectively.

    Science.gov (United States)

    Silva Júnior, João Batista; Costa, Christiane da Silva; Baccara, João Paulo de Araújo

    2015-10-01

    The use of blood products as essential medicines and the recognition of the high risk associated with blood transfusions require governments to take regulatory action with a focus on quality and safety. In this scenario, regulatory agencies play an essential role in socially advancing the guarantee that blood components will be produced according to current operating rules. Thus, in the effort to manage sanitary risks involved in the processing and use of blood, the Brazilian regulatory model, based on the construction of a national blood policy overseen by the State, has undergone conceptual improvement and review of the tools employed to achieve its goals. With the inclusion of good manufacturing practices as part of the Brazilian norms, as recommended by the World Health Organization, the country has moved forward in its view of blood facilities as manufacturing centers producing blood-derived biologics for therapeutic applications. It has also strengthened the need to develop safety mechanisms for blood donors and recipients. The development of a State-coordinated national blood policy and the institution of a national surveillance system with legitimate power of inspection are essential elements used in Brazil to guarantee the amount, quality, safety, and timeliness of blood supply to the population. The present article aims to discuss the present context of the blood regulatory model in Brazil so as to identify the challenges for improvement of this model. PMID:26758225

    Full Text Available Background and Objectives: The blood donor system in the Kingdom of Saudi Arabia depends on a combination of voluntary and involuntary donors. The aim of this study is to explore the attitudes, beliefs and motivations of Saudis toward blood donation. Materials and Methods: The study was conducted at the Donor Centers at King Khalid University Hospital (KKUH Blood Bank and King Saud University Students Health Center, Riyadh. A self-administered questionnaire was distributed to donors (n = 517 and nondonors (n = 316, between February and June 2008. All were males. Results: Ninety-nine percent of the respondents showed positive attitude toward blood donations and its importance for patients care, and object the importation of blood from abroad. Blood donors: Ninety-one percent agree that that blood donation is a religious obligation, 91% think no compensation should be given, 63% will accept a token gift, 34% do not object to donating six times/year and 67% did not mind coming themselves to the donor center to give blood. Nondonors: Forty-six percent were not asked to give blood and those who were asked mentioned fear (5% and lack of time (16% as their main deterrents. Reasons for rejection as donors include underweight and age (71% and health reasons (19%. Seventy-five percent objected to money compensation but 69% will accept token gifts and 92% will donate if a relative/friend needs blood. Conclusion: These results reflect an encouraging strong positive attitude toward blood donation. Further future planning with emphasis on educational/publicity programs and careful organization of donor recruitment campaigns could see the dream of total voluntary nonremunerated blood donations should not take long to be true.

  11. Globalisation and blood safety.

    Science.gov (United States)

    Farrugia, Albert

    2009-05-01

    Globalisation may be viewed as the growing interdependence of countries worldwide through the increasing volume and variety of cross-border transactions in goods and services, and also through the more rapid and widespread diffusion of technology. Globalisation is not just an economic phenomenon, although it is frequently described as such, but includes commerce, disease and travel, and immigration, and as such it affects blood safety and supply in various ways. The relatively short travel times offered by modern aviation can result in the rapid spread of blood-borne pathogens before measures to counteract transmission can be put in place; this would have happened with SARS if the basic life cycle of the SARS virus included an asymptomatic viraemia. This risk can be amplified by ecological factors which effect the spread of these pathogens once they are transferred to a naïve ecosystem, as happened with West Nile Virus (WNV) in North America. The rationalization and contraction of the plasma products industry may be viewed as one aspect of globalisation imposed by the remorseless inevitability of the market; the effect of this development on the safety and supply of products has yet to be seen, but the oversight and assurance of a shrinking number of players will present particular challenges. Similarly, the monopolization of technology, through patent enforcement which puts access beyond the reach of developing countries, can have an effect on blood safety. The challenges presented to blood safety by globalisation are heightening the tensions between the traditional focus on the product safety - zero risk paradigm and the need to view the delivery of safe blood as an integrated process. As an illustration of this tension, donor deferral measures imposed by globalisation-induced risks such as vCJD and WNV have resulted in the loss of the safest and most committed portion of the blood donor population in many Western countries, leading to an increased risk to

For patients for whom no suitable related donor is available, this source of hematopoietic stem cells offers substantial advantages, notably the relative ease of procurement, the absence of risk to the donor, the small likelihood of transmitting clinically important infections, the low risk of severe graft-versus-host disease (GVHD and the rapid availability of placental blood for transplantation centers. Even though almost 80 diseases are treatable with cord blood stem cells, 97 percent of cord blood is still disposed of after birth and lost for patients in need! To improve availability of stem cells to a broader community, efforts should be undertaken to collect cord blood and expectant parents should be properly informed of their options with regard to cord blood banking.

    Full Text Available Transfusions of blood and blood products are commonly used in medicine, but being biological materials they carry a risk of transmitting infections--viral, bacterial, parasitic, as well as prions. Laboratory tests used for screening of donated blood for viral infections at present cannot detect all infectious units.

    2012-01-01

    This study intended to use a human-centered design study method to develop a bar-code technology in blood sampling process. By using the multilevel analysis to gather the information, the bar-code technology has been constructed to identify the patient's identification, simplify the work process, and prevent medical error rates. A Technology Acceptance Model questionnaire was developed to assess the effectiveness of system and the data of patient's identification and sample errors were collected daily. The average scores of 8 items users' perceived ease of use was 25.21(3.72), 9 items users' perceived usefulness was 28.53(5.00), and 14 items task-technology fit was 52.24(7.09), the rate of patient identification error and samples with order cancelled were down to zero, however, new errors were generated after the new system deployed; which were the position of barcode stickers on the sample tubes. Overall, more than half of nurses (62.5%) were willing to use the new system. PMID:24199057

  4. Blood Pump Bearing System

    Aber, Gregory S. (Inventor)

    2000-01-01

    An apparatus is provided for a blood pump bearing system within a pump housing to support long-term highspeed rotation of a rotor with an impeller blade having a plurality of individual magnets disposed thereon to provide a small radial air gap between the magnets and a stator of less than 0.025 inches. The bearing system may be mounted within a flow straightener, diffuser, or other pump element to support the shaft of a pump rotor. The bearing system includes a zirconia shaft having a radiused end. The radiused end has a first radius selected to be about three times greater than the radius of the zirconia shaft. The radiused end of the zirconia shaft engages a flat sapphire endstone. Due to the relative hardness of these materials a flat is quickly produced during break-in on the zirconia radiused end of precisely the size necessary to support thrust loads whereupon wear substantially ceases. Due to the selection of the first radius, the change in shaft end-play during pump break-in is limited to a total desired end-play of less than about 0.010 inches. Radial loads are supported by an olive hole ring jewel that makes near line contact around the circumference of the Ir shaft to support big speed rotation with little friction. The width of olive hole ring jewel is small to allow heat to conduct through to thereby prevent heat build-up in the bearing. A void defined by the bearing elements may fill with blood that then coagulates within the void. The coagulated blood is then conformed to the shape of the bearing surfaces.

    Blood pressure is the force of blood against artery walls. It is measured in millimeters of mercury (mm Hg and recorded as two numbers: systolic pressure (as the heart contracts over diastolic pressure (as the heart relaxes between beats. High blood pressure (hypertension is defined as chronically elevated high blood pressure, with systolic blood pressure (SBP of 140 mm Hg or greater, and diastolic blood pressure (DBP of 90 mm Hg or greater. High blood pressure (HBP, smoking, abnormal blood lipid levels, obesity and diabetes are risk factors for coronary heart disease, the leading cause of death in the US. Lifestyle modifications such as engaging in regular physical activity, quitting smoking and eating a healthy diet (limiting intake of saturated fat and sodium and increasing consumption of fiber, fruits and vegetables are advocated for the prevention, treatment, and control of HBP. As multiple factors influence blood pressure, the effects of each factor are typically modest, particularly in normotensive subjects, yet the combined effects can be substantial. Nutrition plays an important role in influencing blood pressure. Orange juice should be included as part of any low sodium diet and/or any blood pressure reducing eating plan, as it is sodium free, fat-free and can help meet recommended levels of potassium intake that may contribute to lower BP.

    2014-07-01

    Despite a steady increase in total blood collections and voluntary non-remunerated blood donors, China continues to have many challenges with its blood donation system. The country's donation rate remains low at 9%o, with over 60% of donors being first-time donors. Generally there is a lack of adequate public awareness about blood donation. The conservative donor selection criteria, the relatively long donation interval, and the small donation volume have further limited blood supply. To ensure a sufficient and safe blood supply that meets the increasing clinical need for blood products, there is an urgent need to strengthen the country's blood donor management. This comprehensive effort should include educating and motivating more individuals especially from the rural areas to be involved in blood donation, developing rational and evidence-based selection criteria for donor eligibility, designing a donor follow-up mechanism to encourage more future donations, assessing the current donor testing strategy, improving donor service and care, building regional and national shared donor deferral database, and enhancing the transparency of the blood donation system to gain more trust from the general public. The purpose of the review is to provide an overview of the key process of and challenges with the blood donor management system in China. PMID:25254023

    1995-01-01

    This paper describes the organizational structure and the economic impact of blood donation and transfusion in Greece and discusses some alternative aspects of its financing and its costing policy. The cost of blood transfusion is rising in Greece and amounts to nearly 15 billion drachmas per year due to the constant increase in demand and consequently, the price of each unit of blood. The production and distribution of blood on national scale involves meeting the demand for 500.000 units. Blood is mostly given by the friends and relatives of patients (55%) and by voluntary blood donation (30%). Approximately 50% of the blood produced is used in surgery, 20% for cases of beta-thalassaemia, 10% for emergencies and 20% for internal medicine cases. The blood transfusion system is totally funded by the state budget and the value to users is free of charge. The way in which blood is collected and processed differs from one geographical area to another and the unit cost depends on the size of the department concerned, ranging from 60-150 $. The need to control costs and restrain expenditure, in conjunction with guarantees of sufficiency and quality, makes it essential that measures should be taken to introduce economies of scale and encourage competition among blood providers, for increased production, components preparation and rational usage of blood. The introduction of a costing policy becomes necessary in this effort to achieve cost-containment techniques. PMID:8581182

    2011-09-01

    Bloodstain pattern analysis (BPA) refers to the collection, categorization and interpretation of the shape and distribution of bloodstains connected with a crime. These kinds of stains occur in a considerable proportion of homicide cases. They offer extensive information and are an important part of a functional, medically and scientifically based reconstruction of a crime. The following groups of patterns can essentially be distinguished: dripped and splashed blood, projected blood, impact patterns, cast-off stains, expirated and transferred bloodstains. A highly qualified analysis can help to estimate facts concerning the location, quality and intensity of an external force. A sequence of events may be recognized, and detailed questions connected with the reconstruction of the crime might be answered. In some cases, BPA helps to distinguish between accident, homicide and suicide or to identify bloodstains originating from a perpetrator. BPA is based on systematic training, a visit to the crime scene or alternatively good photographic documentation, and an understanding and knowledge of autopsy findings or statements made by the perpetrator and/or victim. A BPA working group has been established within the German Society of Legal Medicine aiming to put the knowledge and practical applications of this subdiscipline of forensic science on a wider basis.

  13. New blood flow radiopharmaceutical

    International Nuclear Information System (INIS)

    Our program for research into the causes of mental disorders such as schizophrenia, manic depressive illness and senile dementia has led us to the development of a new radiopharmaceutical agent, IDNNA (4-iodo-2,5-dimethoxy-N,N-dimethylamphetamine). A series of some 15 different 131I labeled molecules with various substitutions on the amine were synthesized and tested, and the uptake of the 131I labeled conpounds in rats was measured. The dimethyl amine (IDNNA) had the best brain uptake and brain/blood ratio. When injected into a dog and scanned with a whole-body scanner, the uptake in the brain could be clearly seen and quantified. Plasma sampling at the same time showed that the maximum brain/blood ratio of 8.7 occurred at 8 min after injection, and the concentration in brain remained high for at least 15 min. Labeling is achieved by reacting 131ICl and the precursor, 2,5-dimethoxy-N,N-dimethyl amphetamine, in glacial acetic acid; the reaction is complete in less than one minute

    Objectives:: This study is to examine the effect of cadmium exposure on blood pressure in Korean general population. Methods:: The study population consisted of 958 men and 944 women who participated in the 2005 Korean National Health and Nutrition Examination Survey (KNHANES), in which blood pressure and blood cadmium were measured from each participant. Results:: The mean blood cadmium level was 1.67 {mu}g/L (median level 1.55). The prevalence of hypertension was 26.2%. The blood cadmium level was significantly higher among those subjects with hypertension than those without (mean level 1.77 versus 1.64 {mu}g/dL). After adjusting for covariates, the odds ratio of hypertension comparing the highest to the lowest tertile of cadmium in blood was 1.51 (95% confidence interval 1.13 to 2.05), and a dose-response relationship was observed. Systolic, diastolic, and mean arterial blood pressure were all positively associated with blood cadmium level, and this effect of cadmium on blood pressure was markedly stronger when the kidney function was reduced. Conclusions:: Cadmium exposures at the current level may have increased the blood pressure of Korean general population.

  18. Viral metagenomics and blood safety.

    Sauvage, V; Eloit, M

    2016-02-01

    The characterization of the human blood-associated viral community (also called blood virome) is essential for epidemiological surveillance and to anticipate new potential threats for blood transfusion safety. Currently, the risk of blood-borne agent transmission of well-known viruses (HBV, HCV, HIV and HTLV) can be considered as under control in high-resource countries. However, other viruses unknown or unsuspected may be transmitted to recipients by blood-derived products. This is particularly relevant considering that a significant proportion of transfused patients are immunocompromised and more frequently subjected to fatal outcomes. Several measures to prevent transfusion transmission of unknown viruses have been implemented including the exclusion of at-risk donors, leukocyte reduction of donor blood, and physicochemical treatment of the different blood components. However, up to now there is no universal method for pathogen inactivation, which would be applicable for all types of blood components and, equally effective for all viral families. In addition, among available inactivation procedures of viral genomes, some of them are recognized to be less effective on non-enveloped viruses, and inadequate to inactivate higher viral titers in plasma pools or derivatives. Given this, there is the need to implement new methodologies for the discovery of unknown viruses that may affect blood transfusion. Viral metagenomics combined with High Throughput Sequencing appears as a promising approach for the identification and global surveillance of new and/or unexpected viruses that could impair blood transfusion safety.

  5. Sufficient blood, safe blood: can we have both?

    Directory of Open Access Journals (Sweden)

    Bönig Halvard

    2012-03-01

    Full Text Available Abstract The decision in September 2011 in the UK to accept blood donations from non-practicing men who have sex with men (MSM has received significant public attention. Will this rule change substantially boost the number of blood donations or will it make our blood less safe? Clearly, most European countries have a blood procurement problem. Fewer young people are donating, while the population is aging and more invasive therapies are requiring more blood. Yet if that was the reason for allowing non-practicing MSM to donate, clearly re-admission of some other, much larger populations that are currently deferred from donation should likewise be considered. As far as risks for blood safety are concerned, evidence has been provided that the current quality of infectious disease marker testing significantly mitigates against, although does not completely eradicate, risks associated with admission of donors with a high risk of carrying certain blood-transmissible agents. However, it could be argued that more effective recruitment of the non-donor pool, which is substantially larger than the group of currently ineligible donors, would be a better strategy. Recruitment of this group will benefit the availability of blood without jeopardizing the current excellent safety profile of blood.

  6. Tumor Blood Vessel Dynamics

    Science.gov (United States)

    Munn, Lance

    2009-11-01

    ``Normalization'' of tumor blood vessels has shown promise to improve the efficacy of chemotherapeutics. In theory, anti-angiogenic drugs targeting endothelial VEGF signaling can improve vessel network structure and function, enhancing the transport of subsequent cytotoxic drugs to cancer cells. In practice, the effects are unpredictable, with varying levels of success. The predominant effects of anti-VEGF therapies are decreased vessel leakiness (hydraulic conductivity), decreased vessel diameters and pruning of the immature vessel network. It is thought that each of these can influence perfusion of the vessel network, inducing flow in regions that were previously sluggish or stagnant. Unfortunately, when anti-VEGF therapies affect vessel structure and function, the changes are dynamic and overlapping in time, and it has been difficult to identify a consistent and predictable normalization ``window'' during which perfusion and subsequent drug delivery is optimal. This is largely due to the non-linearity in the system, and the inability to distinguish the effects of decreased vessel leakiness from those due to network structural changes in clinical trials or animal studies. We have developed a mathematical model to calculate blood flow in complex tumor networks imaged by two-photon microscopy. The model incorporates the necessary and sufficient components for addressing the problem of normalization of tumor vasculature: i) lattice-Boltzmann calculations of the full flow field within the vasculature and within the tissue, ii) diffusion and convection of soluble species such as oxygen or drugs within vessels and the tissue domain, iii) distinct and spatially-resolved vessel hydraulic conductivities and permeabilities for each species, iv) erythrocyte particles advecting in the flow and delivering oxygen with real oxygen release kinetics, v) shear stress-mediated vascular remodeling. This model, guided by multi-parameter intravital imaging of tumor vessel structure

    Previous studies have identified healthcare practices that may place undue pressure on related donors (RDs) of hematopoietic cell products and an increase in serious adverse events associated with morbidities in this population. As a result, specific requirements to safeguard RD health have been introduced to Foundation for the Accreditation of Cellular Therapy/The Joint Accreditation Committee ISCT and EBMT (FACT-JACIE) Standards, but the impact of accreditation on RD care has not previously been evaluated. A survey of transplant program directors of European Group for Blood and Marrow Transplantation member centers was conducted by the Donor Health and Safety Working Committee of the Center for International Blood and Marrow Transplant Research to test the hypothesis that RD care in FACT-JACIE accredited centers is more closely aligned with international consensus donor care recommendations than RD care delivered in centers without accreditation. Responses were received from 39% of 304 centers. Our results show that practice in accredited centers was much closer to recommended standards as compared with nonaccredited centers. Specifically, a higher percentage of accredited centers use eligibility criteria to assess RDs (93% versus 78%; P = .02), and a lower percentage have a single physician simultaneously responsible for an RD and their recipient (14% versus 35%; P = .008). In contrast, where regulatory standards do not exist, both accredited and nonaccredited centers fell short of accepted best practice. These results raise concerns that despite improvements in care, current practice can place undue pressure on donors and may increase the risk of donation-associated adverse events. We recommend measures to address these issues through enhancement of regulatory standards as well as national initiatives to standardize RD care. PMID:26597079

    Various puncture routes, veins, arteries, heart, are used to take blood in animals. For anatomical reasons, differences in blood composition are expected among puncture sites. However, this issue has been rarely assessed and contrasted results have been reported: strong effects of puncture site versus a lack of effect. We captured free-ranging freshwater turtles from different locations to compare the mean concentrations of 12 blood parameters (metabolites, hormone, ions, and enzyme) among three puncture sites: (1) a lateral branch of the jugular vein, (2) a dorsal subcarapacial cervical plexus (sometimes incorrectly referred as the 'cervical sinus' in the literature), and (3) a caudal plexus site (sometimes incorrectly referred as the 'caudal sinus'). Because we used very small syringes (27-30G), we were able to separate lymph, blood, or blood-lymph mixtures. Our results show very strong effects of puncture site and of mixture level (mean maximal difference between sites was 250 %). We also found strong sex and geographical effects. Typically, there were differences in concentrations of blood solutes sampled from the lateral jugular vein and subcarapacial plexus, mainly due to sampling a mixture of blood and lymph from the 'blood' at the subcarapacial site and pure blood from the lateral jugular site, and likewise, samples from the caudal site were highly variable due to often sampling a mixture of blood and lymph. These results have technical and fundamental implications, especially when performing comparative analyses. Further, by selecting precise puncture sites, physiological differences between lymph and blood compartments could be investigated. PMID:27146147

  11. A new donor system for the patients with thalassemia: "Blood mother and blood father"

    Directory of Open Access Journals (Sweden)

    Canatan Duran

    2010-01-01

    Full Text Available Background : Donor recruitment programs differ in countries depending on local conditions and causes. Regularly voluntary blood donation rate should be 5% of the population but it is extremely low in Turkey. In 1998, "Thalassemia flowers don′t fade" campaigning was started to get regular voluntary blood for patients with thalassemia. We would like to present results of our campaigning. Materials and Methods: The Thalassemia center was established in Antalya on the 1 st June 1994 by Ministry of Health, Turkey, because the incidence of thalassemia is very high in the Antalya region. A total of 388 patients with thalassemia were followed up regularly in the center. The annually blood requirement was approximately 5000 units per year. In 1998, a new program of blood donation for patients with thalassemia called "BLOOD MOTHER and BLOOD FATHER" was started with the support of Governor of Antalya and health management system in Antalya. Results : Between year 1998 and 2006, a total 3000 voluntary blood donors between age 18 and 65 years, of which 2160 males (72% and 840 were females (28%, had participated in this program. Conclusion: "Blood Mother and Blood Father" campaign was successful donor recruitment program for thalassemic care. After 2006, this program is now adopted and run by Turkish Red Crescent and Thalassemia Federation of Turkey for all thalassemics in Turkey.

    International Nuclear Information System (INIS)

    The blood platelet life span was measured by labelling the circulating population in vivo and in vitro. DF32P labelling in vivo: DFP is a specific inhibitor of acetyl-cholinesterase and hence in vivo labels blood platelets in the same way as the red cells and white cells which contain this enzyme. Sodium chromate 51Cr: this is the method used almost universally and the various stages were described. Several parameters were studied: the percentage of blood platelets in circulation, the aspect of the radioactivity decay curve, blood platelet production. Results obtained by the use of a medulla tracer, 75Se selenomethionine, were also reported. Finally the practical use of the blood platelet kinetics measurements were demonstrated

    In order to overcome the stop marketing by Biorad company of automated high performance liquid chromatograph with UV detection (Remedi), we developed a gas chromatography-mass spectrometry (GC-MS) to detect and to give an approximation of the overdose of molecules frequently encountered in drug intoxications. Therefore two hundred eighty seventeen blood samples were collected over a period of one year and allowed us to evaluate and compare the performance of these two techniques. As identification, GC-MS does not identify all molecules detected by Remedi in 24.2% of cases; there is a lack of sensitivity for opiates and the systematic absence of certain molecules such as betablockers. However, in 75.8% of cases the GC-MS detects all molecules found by Remedi and other molecules such as meprobamate, paracetamol, benzodiazepines and phenobarbital. The concentrations obtained are interpreted in terms of overdose showed 15.7% of discrepancy and 84.3% of concordance between the two techniques. The GC-MS technique described here is robust, fast and relatively simple to implement; the identification is facilitated by macro commands and the semi quantification remains manual. Despite a sequence of cleaning the column after each sample, carryover of a sample to the next remains possible. This technique can be used for toxicologic screening in acute intoxications. Nevertheless it must be supplemented by a HPLC with UV detection if molecules such as betablockers are suspected. PMID:20348049

    2010-02-01

    Full Text Available Objective: To assess the effects of percutaneous transluminal angioplasty and stenting (PTRA/S on arterial blood pressure and renal function.Methods: A retrospective chart review of patients undergoing PTRA/S at our institution between December 2003 and September 2006 was done. Follow-up data were derived from hospital records. Estimated glomerular filtration rate (EGFR was used as the marker of renal function. To evaluate the pre- and post-procedure values in individual patients the paired t test and Wilcoxon signed-rank tests were used.Results: Thirty-six patients (16 women, 30 men; mean age 59±15 years, range: 25-83 years underwent 43 PTRA/S interventions at our institution. The mean duration of follow-up was 9.3±8.6 (range 2-28 months. We observed no significant change in EGFR from pre-procedure to that obtained at follow-up (71.4±40.2 mL/min vs.73.3±39.0 mL/min; p=0.483. Mean arterial blood pressure (MABP, however, was reduced significantly: pre-procedure MABP-123±22 mmHg; post-procedure follow-up value of 101±14 mmHg (p <0.001. The mean number of antihypertensive medications used at the time of intervention was 2.1±1.0 (range: 0-4, whereas at follow-up, this number had decreased to 1.3±1.0 (range: 0-4; p<0.001. In patients with renal impairment (EGFR ≤59 mL/min, 41% showed improvement, 29% showed no change and 29% demonstrated deterioration in EGFR. Conclusion: PTRA/S may preserve renal function, especially in patients with pre-procedural impaired renal function.

    1988-08-01

    Autologous transfusion, storage of one's own blood for subsequent infusion if needed, is safe and effective in a variety of scheduled operative procedures. Obstetric involvement in such programs is very limited, however. Thirty pregnant women with placenta previa or other potential complications underwent 55 phlebotomies in an autologous transfusion program. Phlebotomies were performed at an average gestational age of 32.4 weeks (range 13-40). Changes in mean diastolic blood pressure and pulse were minimal. Electronic fetal monitoring tracings were normal during the 34 procedures in which it was used. The frequency of mild donor reactions (4%) was consistent with that in nonpregnant donors. After entry into this program, 15 patients received a total of 29 U of packed red blood cells (23 autologous; six homologous). Homologous transfusion was avoided in 86.7% of patients receiving blood. Selected pregnant women can participate safely in autologous blood collection programs, minimizing the need, and therefore the risks, of homologous transfusion. PMID:3292974

  5. Gastric mucosal blood flow measurement

    International Nuclear Information System (INIS)

    Pertechnetate clearance (C/sub Tc/) by the stomach before and after betazole stimulation was compared to regional measurements of gastric blood flow utilizing nuclide (Chromium-51 and Cerium-141)-labeled microspheres in five piglets. Pertechnetate clearance closely correlated (correlation coefficient 0.926) with mucosal blood flow in the gastric corpus measured by the microsphere technique. Betazole increased blood flow in the corpus region by 100 percent but did not alter this relationship. Except in one experiment, microsphere blood flow valves in the antrum and fundus were unchanged by betazole and did not significantly correlate with pertechnetate clearance. Pertechnetate clearance appears to be a reliable method of determining gastric mucosal blood flow in experimental animals and may be considered as a noninvasive method for measuring such flow in humans.

    Since November 2015, Puerto Rico has reported active mosquito-borne transmission of Zika virus (1). Because of the potential for Zika virus to be transmitted through transfusion of blood components, and because a high percentage of persons infected with Zika virus are asymptomatic (2), the Food and Drug Administration (FDA) recommended that blood collections cease in areas of the United States affected by active vector-borne transmission of Zika virus until laboratory screening of blood donations or pathogen reduction technology (PRT)* for treatment of blood components can be implemented (3). To inform efforts to maintain the safety and availability of the blood supply in Puerto Rico, CDC, in collaboration with the Puerto Rico Department of Health, conducted a rapid assessment of blood collection and use on the island. A total of 139,369 allogeneic red blood cell (RBC) units,(†) 45,243 platelet units, and 56,466 plasma units were collected in or imported to Puerto Rico during 2015, and 135,966 allogeneic RBC units, 13,526 therapeutic platelet units,(§) and 25,775 plasma units were transfused. Because of the potential for local Zika virus transmission in areas with a competent mosquito vector (4), other areas of the United States should develop plans to ensure local blood safety and adequacy. Blood collection organizations and public health agencies should collaborate to maintain the safety and availability of local blood supplies in accordance with FDA guidance. PMID:27078190

  8. Microfluidic Devices for Blood Fractionation

    2011-07-01

    Full Text Available Blood, a complex biological fluid, comprises 45% cellular components suspended in protein rich plasma. These different hematologic components perform distinct functions in vivo and thus the ability to efficiently fractionate blood into its individual components has innumerable applications in both clinical diagnosis and biological research. Yet, processing blood is not trivial. In the past decade, a flurry of new microfluidic based technologies has emerged to address this compelling problem. Microfluidics is an attractive solution for this application leveraging its numerous advantages to process clinical blood samples. This paper reviews the various microfluidic approaches realized to successfully fractionate one or more blood components. Techniques to separate plasma from hematologic cellular components as well as isolating blood cells of interest including certain rare cells are discussed. Comparisons based on common separation metrics including efficiency (sensitivity, purity (selectivity, and throughput will be presented. Finally, we will provide insights into the challenges associated with blood-based separation systems towards realizing true point-of-care (POC devices and provide future perspectives.

    Despite considerable advances in the safety of blood components, transfusion associated bacterial infection (TABI) remains an unresolved problem. As yet there are no perfect preventative, screening and/or detection methodologies for eliminating contaminated units. Until a practical, rapid, cost-effective and logistically acceptable test becomes available, we should be satisfied with the choice of various limited solutions that at least partially improve the bacterial safety of blood components. It is also necessary to establish standardised guidelines and agreed upon systematic procedures for the recognition and reporting of the laboratory and clinical evaluation of adverse reactions in recipients of contaminated blood components.

  12. Significance of irradiation of blood

    International Nuclear Information System (INIS)

    Many reports of fatal GVHD occurring in non-immunocompromised patients after blood transfusion have been published in Japan. One explantation is that transfused lymphocytes were simulated and attack the recipient organs recognized as HLA incompatible. That is so called 'one-way matching'. To reduce the risk of post-transfusion GVHD, one of the most convenient methods is to irradiate the donated blood at an appropriate dose for inactivation of lymphocytes. Because no one knows about the late effect of irradiated blood, it is necessary to make the prospective safety control. (author)

    Pursuing their chief work--gathering, processing and distributing blood--the blood donor centres of the Canadian Red Cross Society follow standard operating procedures like those in place at the Ottawa centre. Here, recruitment staff and volunteers work to recruit donors to meet needs at a time when the number of donors is falling. When they register, donors must show proof of identity. Each receives a permanent identification number that is linked to the numbers assigned to the units of bloo...

    Full Text Available Neetu Tyagi*, Thomas P Vacek*, John T Fleming, Jonathan C Vacek, Suresh C TyagiDepartment of Physiology and Biophysics, School of Medicine, University of Louisville, Louisville, KY, USA *These authors have equal authorshipAbstract: Elevated plasma levels of homocysteine (Hcy, known as hyperhomocysteinemia (HHcy, are associated with osteoporosis. A decrease in bone blood flow is a potential cause of compromised bone mechanical properties. Therefore, we hypothesized that HHcy decreases bone blood flow and biomechanical properties. To test this hypothesis, male Sprague–Dawley rats were treated with Hcy (0.67 g/L in drinking water for 8 weeks. Age-matched rats served as controls. At the end of the treatment period, the rats were anesthetized. Blood samples were collected from experimental or control rats. Biochemical turnover markers (body weight, Hcy, vitamin B12, and folate were measured. Systolic blood pressure was measured from the right carotid artery. Tibia blood flow was measured by laser Doppler flow probe. The results indicated that Hcy levels were significantly higher in the Hcy-treated group than in control rats, whereas vitamin B12 levels were lower in the Hcy-treated group compared with control rats. There was no significant difference in folate concentration and blood pressure in Hcy-treated versus control rats. The tibial blood flow index of the control group was significantly higher (0.78 ± 0.09 flow unit compared with the Hcy-treated group (0.51 ± 0.09. The tibial mass was 1.1 ± 0.1 g in the control group and 0.9 ± 0.1 in the Hcy-treated group. The tibia bone density was unchanged in Hcy-treated rats. These results suggest that Hcy causes a reduction in bone blood flow, which contributes to compromised bone biomechanical properties.Keywords: homocysteine, tibia, bone density

    2015-01-01

    The choriocapillaris is a capillary bed located in a thin layer adjacent to the outer retina and is part of the oxygen delivery system to the photoreceptors of the eye. The blood flow is approximately planar and is serviced by microvessels, which join the choriocapillaris through inlets perpendicular to its plane. Capillaries are densely organised and separated by avascular septal posts, which direct the blood flow. The capillary bed is composed of a juxtaposition of tessellating vascular uni...

    This study examined the role of ethnicity on the aerobic fitness, blood pressure, and selected blood chemistry values of women. One hundred twenty-four females (mean age 41.37 +/- 9.0) were medically Examined at the NASA/Johnson Space Center occupational health clinic. Ethnic groups consisted of 23 Black (B), 18 Hispanic (H) and 83 Non-minority (NM). Each woman had a maximum Bruce treadmill stress test (RER greater than or = 1.1) and a negative ECG. Indirect calorimetry, skinfolds, self-report physical activity (NASA activity scale), seated blood pressure, and blood chemistry panel determined VO2max, percent fat, level of physical activity, blood pressure and blood chemistry values. ANOVA revealed that the groups did not differ (p greater than 0.05) in age, VO2 max, weight, percent fat, level of physical activity, total cholesterol, or HDL-C. However, significant differences (p greater than 0.05) were noted in BMI, diastolic blood pressure, and blood chemistries. BMI was 3.17 higher in H than in NM; resting diastolic pressures were 5.69 and 8.05 mmHg. lower in NM and H than in B; triglycerides were 48.07 and 37.21 mg/dl higher in H than in B and NM; hemoglobin was .814 gm/dl higher in NM than B; fasting blood sugar was 15.41 mg/dl higher in H than NM; The results of this study showed that ethnic groups differed in blood pressure and blood chemistry values but not aerobic fitness or physical activity. There was an ethnic difference in BMI but not percent fat.

  15. SPECT of brain blood flow

    International Nuclear Information System (INIS)

    Morphological observation of the brain became possible by CT and various informations on vascularity and damages in brain blood barrier (BBB) became obtainable by the combined use of contrast medium. Then the appearance of MRI had enabled to discriminate the cortex and the medula of the brain and to perform MR angiography. However, it was still difficult to observe the cerebral tissue in detail. Recently, nuclear medical procedures have been developed and applied to diagnosis. SPECT images attributable to the distribution of γ-ray from a tracer, which monitors the blood flow and various metabolisms. Thus, investigations of cerebral functions including blood flow metabolism and neural transmission etc. became possible by the technique. Here, SPECT by Xe-133 clearance and 99mTc HMPAO methods were reviewed. For Xe-133 method, subjects positioned in SPECT instrument underwent bolus inhalation of Xe-133, 1850 Mbq followed by washout respiration of room air. During these treatment, cerebral projection and determination of the concentration of Xe-133 CO2 in the expired air were continuously carried out. And the blood flow level per pixel was estimated from SPECT images and the end-tidal Xe-133 concentration curve. This method was thought to be the most excellent method for the determination of local blood flow in respect of accuracy and reproducibility. The tracer distribution expressed the functional level of the stagnant state of blood flow. SPECT provides useful informations to investigate the physiological functions and pathology in the brain.

    Plastic blood bags improve the safety and effectiveness of blood component separation and storage. Progress towards optimal storage systems is driven by medical, scientific, business and environmental concerns and is limited by available materials, consumer acceptance and manufacturing and regulatory concerns. Blood bag manufacturers were invited to submit lists of the bags they manufacture. The lists were combined and sorted by planned use. The lists were analysed by experts to assess the degree to which the products attend to scientific problems. Specific issues addressed included the use of di-ethylhexyl phthalate (DEHP) as plasticizer for polyvinyl chloride (PVC) blood bags, the size, material and thickness of platelet bags, and the fracture resistance of plasma bags. Alternatives to DEHP for red blood cell (RBC) storage exist, but are mostly in a developmental stage. Plastic bags (DEHP-free, PVC-free) for platelet storage with better gas diffusion capabilities are widely available. Alternatives for plasma storage with better fracture resistance at low temperatures exist. Most RBC products are stored in DEHP-plasticized PVC as no fully satisfactory alternative exists that ensures adequate storage with low haemolysis. A variety of alternative platelet storage systems are available, but their significance - other than improved oxygen transport - is poorly understood. The necessity to remove DEHP from blood bags still needs to be determined. PMID:24102543

    Background. To ensure an adequate supply of blood, collection centers must design campaigns that successfully recruit and maintain an active donor pool. Understanding factors that motivate and deter individuals from donating may help centers develop targeted recruitment campaigns. These factors among high school aged blood donors have not yet been fully investigated. Study Design and Methods. A voluntary, anonymous survey was administered to student donors at high school mobile blood drives. The survey instrument asked the students to rate several potential motivating factors in their importance in the decision to donate blood and several potential deterring factors in their future decision whether or not to donate blood again. The survey also asked the students to rate the desirability of several potential incentives. Results. Motivating factors that reflected prosocial, empathetic, and altruistic thoughts and beliefs were rated highly by students. Pain from phlebotomy was most commonly chosen as potential deterrent. Movie tickets and cookies/snacks at the drive were rated as the most attractive incentives. Conclusion. High school aged blood donors are similar to other donor groups in their expressed motives for donating blood. This group may be unique in the factors that deter them from donating and in their preferences for different incentives. PMID:27293985

    Full Text Available Introduction: Everyday, millions of people around the world go through phlebotomy, either to donate blood or for therapeutic intention. The most important worrisome adverse effects are hemodynamic alterations. In this study, hemodynamic changes following blood donation were assessed. Methods & Materials: Three hundred laborers who donated blood voluntarily were enrolled in this study. Blood pressure (BP and pulse rate were measured before the procedure, ten minutes afterwards, and one week following phlebotomy. Hemoglobin (Hgb and hematocrit (Hct were also determined prior to and one week after phlebotomy. Finally, results before and after donation were compared with each other. Results: 242 volunteers had normal BP and 58 were hypertensive. The mean systolic blood pressures (SBP before phlebotomy, ten minutes after the procedure, and one week later were 120, 117, and 122 mmHg, respectively. During the same periods of time, the mean of diastolic blood pressures (DBP were 77 , 78 and 78 mmHg , in order , while pulse rates on average were 80 , 82 and 76 beats/minute . None of the aforementioned changes were clinically significant. After one week, Hgb decreased by about 0.3 g/dl (P<0.001 and Hct declined on average of 1.7 (P<0.001. Forty six individuals had high DBP and one week after donation, their DBP was reduced by 7 mmHg. Age, body mass index and smoking did not have any significant effect on hemodynamic status. Conclusion: Hemodynamic changes in healthy blood donors were not clinically significant. It seems that DBP drops desirably in hypertensive individuals. This needs to be evaluated more carefully in future studies.

    Full Text Available Abstract Background Blood cultures are a gold standard specific test for diagnosing many infections. However, the low yield may limit their usefulness, particularly in low-risk populations. This study was conducted to assess the utility of blood cultures drawn from ambulatory outpatients. Methods Blood cultures drawn at community-based collection sites in the Calgary Health Region (population 1 million in 2001 and 2002 were included in this study. These patients were analyzed by linkages to acute care health care databases for utilization of acute care facilities within 2 weeks of blood culture draw. Results 3102 sets of cultures were drawn from 1732 ambulatory outpatients (annual rate = 89.4 per 100,000 population. Significant isolates were identified from 73 (2.4% sets of cultures from 51 patients, including Escherichia coli in 18 (35% and seven (14% each of Staphylococcus aureus and Streptococcus pneumoniae. Compared to patients with negative cultures, those with positive cultures were older (mean 49.6 vs. 40.1 years, p Conclusion Blood cultures drawn in outpatient settings are uncommonly positive, but may define patients for increased intensity of therapy. Strategies to reduce utilization without excluding patients with positive cultures need to be developed for this patient population.

    2013-01-01

    Full Text Available Introduction. Blood groups are inherited biological characteristics that do not change throughout life in healthy people. Blood groups represent antigens found on the surface of red blood cells. Kell blood group system consists of 31 antigens. Kell antigen (K is present in 0.2% of the population (the rare blood group. Cellano antigen is present in more than 99% (the high-frequency antigen. These antigens have a distinct ability to cause an immune response in the people after blood transfusion or pregnancy who, otherwise, did not have them before. Case Report. This paper presents a blood donor with a rare blood group, who was found to have an irregular antibody against red blood cells by indirect antiglobulin test. Further testing determined the specificity of antibody to be anti-Cellano. The detected antibody was found in high titers (1024 with erythrocyte phenotype Kell-Cellano+. The blood donor was found to have a rare blood group KellKell. This donor was excluded from further blood donation. It is difficult to find compatible blood for a person who has developed an antibody to the high-frequency antigen. The donor’s family members were tested and Cellano antigen was detected in her husband and child. A potential blood donor was not found among the family members. There was only one blood donor in the Register of blood donors who was compatible in the ABO and Kell blood group system. Conclusion. For the successful management of blood transfusion it is necessary to establish a unified national register of donors of rare blood groups and cooperate with the International Blood Group Reference Laboratory in Bristol with the database that registers donors of rare blood groups from around the world.

    Malaria is a major public health problem in Ethiopia. Over the past years, the disease has been consistently reported as the first leading cause of outpatient visits, hospitalization and death in health facilities across the country. Thus, a retrospective study was conducted to determine the prevalence of malaria from peripheral blood smear examination from the Serbo Health Center of Ethiopia. The case notes of all malaria cases treated between July 2007 and June 2008 were carefully reviewed and analyzed. Of the total 6863 smears, 3009 were found to be positive and contribute 43.8% of diagnostic yield. Plasmodium falciparum constituted the most predominant [64.6% (1946/3009 cases)], while Plasmodium vivax confirmed with 34.9% (1052/3009) cases. Among patients who underwent diagnostic testing and treatment for malaria, males [63.8% (1918/3009 cases)] were more prone to have a positive malaria smear than females [36.2% (1091/3009 cases)]. Chi-square statistical analysis shown that there was a statistically significant association found between male cases and number of positive blood smear (chi(2)=28.1; df=7; p-value=0.001). The present study results clearly suggest that the catchment area of Serbo Health Center is prone for epidemic malaria and the situation is quite deteriorating. At the moment, although we are not equipped with magic bullet for malaria effective low-cost strategies are available for its treatment, prevention, and control. Therefore, creating awareness by active health education campaigns and applying integrated malaria control strategy could bring the constructive outcome in the near future. PMID:20701879

    To maintain a constant supply of "universal blood type", or group O red blood cells, has benefit in specialized transfusion condition. In this study, α-galactosidase cDNA was cloned from Catimor coffee bean grown in Hainan island, China, by the RT-PCR method. We have constructed a vector for α-galactosidase cDNA expression and transferred α-galactosidase cDNA into Pichia pastoris GS115 cells by electroporation. The recombinant α-galactosidase (r-α-GalE) was purified by cation ion exchange chromatography. After studying the biochemical characters of r-α-GalE, we have succeeded in converting human erythrocytes from group B to group O. The animal experiment showed that transfusion of enzymetically converted group O red blood cells (ECORBC) was perfectly safe.

    In this paper an endovascular measurement system used for intraoperative cerebral blood flow monitoring is described. The system is based on a Volcano ComboMap Pressure and Flow System extended with analogue-to-digital converter and PC laptop. A series of measurements performed in patients with cerebrovascular pathologies allows us to introduce “velocity-pressure” and “flow rate-energy flow rate” diagrams as important characteristics of the blood flow. The measurement system presented here can be used as an additional instrument in neurosurgery for assessment and monitoring of the operation procedure. Clinical data obtained with the system are used for construction of mathematical models and patient-specific simulations. The monitoring of the blood flow parameters during endovascular interventions was approved by the Ethics Committee at the Meshalkin Novosibirsk Research Institute of Circulation Pathology and included in certain surgical protocols for pre-, intra- and postoperative examinations.

    Blood is a shear-thinning fluid. At shear rates γ˙ rouleaux'' formed by stacked red blood cells (RBCs). For higher γ˙ in the range 10 - 1000 s-1 , where RBCs flow as single elements, studies demonstrated that RBCs suspended in a viscous fluid mimicking the viscosity of whole blood, deformed into ellipsoids aligned steadily in the direction of the flow, while their membrane rotated about their center of mass like a tank-tread. Such drop-like behavior seemed to explain shear-thinning. Here, using rheometers, microfluidics and simulations, we show that the dynamics of single RBCs in plasma-like fluids display a different sequence of deformation for increasing shear rates going from discocytes to successively, stomatocytes, folded stomatocytes, trilobes and tetralobes, but never ellipsoids. This result is also identical for physiological hematocrits. We correlate this shape diagram to the different regimes in blood rheology for high shear rates and propose a new-look on the interpretation of blood shear-thinning behavior.

    In order to answer to its aim of standardised self-sufficiency, the Établissement français du sang (main French national platform for blood donation) needs to know well the donors, what moves them, what motivates them, and the meaning that they give to their action. This knowledge allows the EFS to better understand the different sensitivities among donors, and therefore to improve the strategy regarding loyalty or/and newcomers. In this paper we follow, without attempting to be fully exhaustive, the evolution of the research regarding blood donation. The aim is to highlight the role played by social and historical representations regarding donation in general. In a given community, its norms, and its values influence both the image of donors as well as the meaning attached to the act itself of donation. Moreover, these norms have also influenced the way that research has tried to analyse this topic. The initial studies conducted in this field tried generally to understand the meaning and the symbolism attached to the act of blood donation. Later on, researchers started to focus on the assessment of notions such as generosity, and then solidarity. Nowadays, research is more focused on describing the population that gives blood. They are more scrutinised through their socio-demographic traits (who they are) than through the specific study of how they donate, the reasons behind the decision to act and the notion of satisfaction.

    1961-01-01

    Intraspecific differences in erythrocyte antigens (blood types) were shown to occur in four species of Pacific salmon, the sockeye or red salmon (Oncorhynchus nerka), the chinook or king salmon (0. tshawytscha), the chum salmon (O. keta), and the pink salmon (O. gorbuscha). Antisalmon-erythrocyte sera prepared in rabbits and chickens were used after absorption of species-specific antibodies. Some of these blood types were shown to differ in their frequency of occurrence between different geographic races. In addition, isoimmunizations were conducted on one race of sockeye salmon. Antisera of seven different specificities were prepared and at least eight different patterns of antigenic composition were displayed by the cells tested.

    The blood vessels in the lung of the goat, which until now have received little attention, are described in detail for the first time. With regard to the segments of the lung, blood vessels are bronchovascular units in the lobi craniales, lobus medius and lobus accessorius, but bronchoartery units in the lobi caudales. We investigated the types of branches of the Aa. pulmonales dextra et sinistra, the inter- and intraspecific principles of the outlet of the pulmonary veins and the importance of bronchopulmonary segmentation of the lungs.

    West Nile virus (WNV) can be transmitted by blood transfusions and organ transplants. This study was a retrospective study which was performed in Blood Transfusion Center to evaluate the WNV infection in blood donors in Iran. A total of 540 blood samples were taken from volunteer healthy donors who referred for blood donation to Chabahar Blood Center. The presence of WNV was studied by detecting immunoglobulin G (IgG) WNV by enzyme linked immune sorbent assay (ELISA). Demonstration of elevated WNV IgG confirmed by immunoflouorescence assay (IFA) Euroimmun kit. Out of the 540 samples 17.96 % (97 cases) were seropositive by ELISA and 1.48 % (8 cases) was seropositive by IFA. This means that 8.24 % of ELISA seropositive samples were confirmed by IFA. Special attention should be paid to criteria of donor selection, albeit positive results may be due to a previous infection in these donors. PMID:27429528

    The New Jersey Superior Court has ruled that the American Association of Blood Banks (AABB), the nation's largest blood bank trade group, was negligent during the early 1980s when it recommended that blood banks not screen and test donors to reduce the chance of HIV contamination of the nation's blood supply. [Name removed], who received HIV-contaminated blood in 1984 as a result of a transfusion at St. Joseph's Hospital in Paterson, sued and reached out-of-court settlements with his doctors and the Bergen Community Blood Center, which provided the blood. Only the AABB suit proceeded to trial, with the jury finding that one-third of the damages were attributable to the AABB's actions. In 1983, the Centers for Disease Control and Prevention (CDC) suggested that blood banks might reduce the risk of AIDS entering the blood supply by using the surrogate hepatitis B test. The AABB, the American Red Cross, and the Council of Community Blood Centers recommended against testing, saying that evidence of transmission by blood was inconclusive and unproven. In March 1985, the AABB adopted the ELISA test. This is the first time the AABB has been held responsible; the AABB said it may appeal the decision. The court disagreed with AABB's claim that it was immune from liability because it was a charity, saying it also performs a critical governance function in respect of the operation of blood banks. The decision puts considerable liability for the U.S. cases of HIV contracted through tainted blood transfusions on the AABB. PMID:11362633

    International Nuclear Information System (INIS)

    The shooting deaths of two community and environmental activists in Nigeria and the involvement of the U.S.-based Chevron Corporation was discussed. The two youths killed were part of a three-day protest on Chevron's Parabe drilling platform. The 200 activists wanted the company to take responsibility for environmental degradation and to contribute more to their impoverished communities to redress the damage caused by pollution and gas flaring that have depleted fish stocks and disrupted forestry practices. The platform protesters were demanding environmental restoration, riverbank construction to prevent loss of drinking water, social services, infrastructure and compensation for trees, lost land and polluted fishing waterways. On May 28, 1999, after three days of protest, military helicopters landed and mobile police and naval personnel opened fire, killing two and injuring 30. Chevron claims that as a joint-venture partner with the government, it had no choice, but to cooperate with the national government's decision to stage a military retaliation. Chevron maintains that in general, it has a good relationship with the local communities, that the group that seized the Parabe platform were not locals, in fact, the protesters' actions were denounced by locals. Further, Chevron states that it has shown strong commitment to environmental protection in Nigeria, as a result of which it has won many good-practice awards from the Nigerian government. Meanwhile, there is a lawsuit pending against Chevron. According to a lawyer from the Center for Constitutional Rights there is a strong claim against Chevron for complicity in human rights violation

    The ratio between the amount of hemoglobin in the mature erythrocyte population and the reticulocytes (RBCHb:RetHb ratio) has previously been suggested as a marker to screen for EPO-abuse. We speculated that the reinfusion of blood would lead to a marked increase in this ratio, making it a valuable...... parameter in the screening for autologous blood doping. Three bags of blood (approximately 201+/-11 g of Hb) were withdrawn from 16 males and stored at either -80 degrees C (-80 T, n=8) or +4 degrees C (+4 T, n=8) and reinfused 10 weeks or 4 weeks later, respectively.

    Han, Song-I.; Marseille, Oliver; Gehlen, Christa; Blümich, Bernhard

    2001-09-01

    Pipe flow of blood in tubes of 1 and 7 mm inner diameter, respectively, was investigated employing two-dimensional NMR velocity imaging and PFG propagator measurements at different Reynolds numbers between 10 and 3500. The results are compared to flow of a water/glycerol mixture of matching viscosity under identical conditions. The transition from laminar to turbulent flow is observed by both a flattening of the velocity profile and a change of the propagator shape. For blood flow this transition is found to be shifted toward higher Reynolds numbers as compared to the transition of the water/glycerol mixture. This observation is in agreement with predictions from hydraulic measurements and is a consequence of the non-Newtonian flow characteristics of blood as a suspension of erythrocytes and plasma. Likewise, a deviation from the laminar flow condition is observed for blood at low Reynolds numbers between 10 and 100. This phenomenon is unknown for Newtonian liquids and is explained by the onset of a geometrical arrangement of the erythrocytes, the so-called rouleaux effect.

  1. Blood lead levels in Jamaican school children

    2001-03-26

    Blood lead levels are reported for a total of 421 schoolchildren in 13 schools in rural and urban environments in Jamaica, including one highly contaminated community. In the rural areas blood lead levels ranged from 3 to 28.5 {mu}g dl{sup -1}, with a median of 9.2 {mu}g dl{sup -1}; the range and median in the urban schools were 4-34.7 and 16.6 {mu}g dl{sup -1}, respectively. Forty-two percent of the rural and 71% of the urban blood lead levels exceeded the US Centers for Disease Control and Prevention intervention level of 10 {mu}g dl{sup -1}. Except in the contaminated area, the relationship between soil lead levels, which in Jamaica are in general typical of tropical lateritic soils, and blood lead levels is not clear-cut. Very high blood lead levels of 18 to >60 {mu}g dl{sup -1} with a median of 35 {mu}g dl{sup -1} were observed among children in the contaminated area, the site of a former lead ore processing plant. These high blood lead levels were significantly reduced, by the implementation of relatively simple mitigation strategies which involved isolation of the lead, education, and a food supplementation programme, to levels similar to those observed in the urban schools. These values, however, remain higher than are desirable and unfortunately, all the sources of lead are not yet identified. The recent discontinuation of the use of leaded petrol is expected to result in significant reductions in exposure to lead.

    Full Text Available Paediatric patients undergoing surgical procedures commonly require some volume of blood or blood component replacement in the perioperative period. Paediatric patients undergoing major surgery associated with substantial blood loss should be evaluated pre-operatively. Pre-operative correction of anaemia may be done considering the age, plasma volume status, clinical status and comorbidities. Maximum allowable blood loss (MABL for surgery must be calculated, and appropriate quantity of blood and blood components should be arranged. Intraoperative monitoring of blood loss should be done, and volume of transfusion should be calculated in a protocol based manner considering the volemia and the trigger threshold for transfusion for the patient and the MABL. Early haemostasis should be achieved by judicious administration of red blood cells, blood components and pharmacological agents.

  3. Ocular Blood Flow Autoregulation Mechanisms and Methods

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available The main function of ocular blood flow is to supply sufficient oxygen and nutrients to the eye. Local blood vessels resistance regulates overall blood distribution to the eye and can vary rapidly over time depending on ocular need. Under normal conditions, the relation between blood flow and perfusion pressure in the eye is autoregulated. Basically, autoregulation is a capacity to maintain a relatively constant level of blood flow in the presence of changes in ocular perfusion pressure and varied metabolic demand. In addition, ocular blood flow dysregulation has been demonstrated as an independent risk factor to many ocular diseases. For instance, ocular perfusion pressure plays key role in the progression of retinopathy such as glaucoma and diabetic retinopathy. In this review, different direct and indirect techniques to measure ocular blood flow and the effect of myogenic and neurogenic mechanisms on ocular blood flow are discussed. Moreover, ocular blood flow regulation in ocular disease will be described.

    In preparing to support the Army in 2025 and beyond, the Army Blood Program remains actively engaged with the research and advanced development of blood products and medical technology to improve blood safety and efficacy in conjunction with the US Army Medical Research and Materiel Command. National and International Blood Bank authorities have noted that the US Army research and development efforts in providing new blood products and improving blood safety operate on the cutting edge of technology and are transformational for the global blood industry. Over the past 14 years, the Army has transformed how blood support is provided and improved the survival rate of casualties. Almost every product or process developed by or for the military has found an application in treating civilian patients. Conflicts have many unwanted consequences; however, in times of conflict, one positive aspect is the identification of novel solutions to improve the safety and efficacy of the blood supply.

  5. Blood histamine release: A new allergy blood test

    International Nuclear Information System (INIS)

    Allergen-mediated histamine release from human leukocytes represents an important model for in vitro studies of allergic reactions. The purpose of this study was to determine whether the measurement of histamine released in allergic patients (pts) by radioenzymatic assay following mixing of their blood with common allergens represents a reliable index for diagnosis of atopic allergy. Three categories of allergies were used: (1) housedust and mite; (2) cat and dog dander; (3) trees and grasses and ragweed mixture. The presence of allergy was established by intradermal skin testing in the study group of 82 pts. Significant atopy was defined as ≥ 3+ (overall range 0-4 +, negative to maximum) on skin testing. The test was carried out in tubes with 0.5 ml heparinized blood, 0.5 ml tris albumin buffer, and one of the allergens (60-100 PNU/ml). In 20 controls without allergy, there always was ≤ 4% histamine release (normal response). A significant allergen-mediated histamine release, ranging from 12 to 30% of the total blood histamine content, was observed in 96% of the pts with skin test sensitivity of ≥ 3+. There was good agreement between skin testing and histamine release in terms of the allergen causing the response. Thus, measurement of histamine release in blood in response to allergen challenge represents a clinically useful in vitro test for the diagnosis of atopic allergy. Because data can be obtained from a single sample and are highly quantitative, this new method should have application to the longitudinal study of allergic pts and to the assessment of interventions

    Full Text Available To better understand the pathophysiology of B cell populations—the precursors of antibody secreting cells—during chronic human immunodeficiency virus (HIV infection, we examined the phenotype of circulating B cells in newly diagnosed Africans. We found that all African individuals displayed low levels of naive B cells and of memory-type CD27+ B cells, and high levels of differentiated B cells. On the other hand, HIV-infected African patients had a population of germinal center B cells (i.e. CD20+, sIgM-, sIgD+, CD77+, CD138±, which are generally restricted to lymph nodes and do not circulate unless the lymph node architecture is altered. The first observations could be linked to the tropical environment whereas the presence of germinal center B cells may be attributable to chronic exposure to HIV as it is not observed in HIV-negative African controls and HAART treated HIV-infected Europeans. It may impact the management of HIV infection in countries with limited access to HIV drugs and urges consideration for implementation of therapeutic vaccines.

    Historically, blood transfusion has been divised, enhanced and organized by physicians. The special status of blood led to ensure that collection of blood and its components were placed under the supervision of a physician. Throughout its history, blood transfusion organization in France has established an exclusive exercise of the collection of blood and its components entrusted to doctors, thus creating the concept of "medicine of donation". This view is changing, and programmed exercise of this activity by nurses led to question about this profession perimeter, its necessary evolution, and finally about the place of physicians in blood supply.

    Full text: We are observing and measuring the varying development reaction stages of blood cells to different saline solutions. The imaging process is based on a common path interferometer which is realized with a spatial light modulator (SLM) in the Fourier plane after the microscope objective. With the SLM we can shift the phase of the transmitted light with respect to the phase of signal wave. This principle is used for the phase contrast microscopy method where we take four pictures of the same image with different phase shifts in order to calculate the complex field of the measured cell. This microscope technique obtains quantitative data about the blood cell's surface in different development stages, amplitude and phase differences inside the cell itself. (author)

    Blood glucose is often elevated in acute stroke, and higher admission glucose levels are associated with larger lesions, greater mortality and poorer functional outcome. In patients treated with thrombolysis, hyperglycemia is associated with an increased risk of hemorrhagic transformation of...... infarcts. For a number of years, tight glycemic control has been regarded as beneficial in critically illness, but recent research has been unable to support this notion. The only completed randomized study on glucose-lowering therapy in stroke has failed to demonstrate effect, and concerns relating to the...... risk of inducing potentially harmful hypoglycemia has been raised. Still, basic and observational research is overwhelmingly in support of a causal relationship between blood glucose and stroke outcome and further research on glucose-lowering therapy in acute stroke is highly warranted....

  18. Breakfast, blood glucose, and cognition.

    Benton, D; Parker, P Y

    1998-04-01

    This article compares the findings of three studies that explored the role of increased blood glucose in improving memory function for subjects who ate breakfast. An initial improvement in memory function for these subjects was found to correlate with blood glucose concentrations. In subsequent studies, morning fasting was found to adversely affect the ability to recall a word list and a story read aloud, as well as recall items while counting backwards. Failure to eat breakfast did not affect performance on an intelligence test. It was concluded that breakfast consumption preferentially influences tasks requiring aspects of memory. In the case of both word list recall and memory while counting backwards, the decline in performance associated with not eating breakfast was reversed by the consumption of a glucose-supplemented drink. Although a morning fast also affected the ability to recall a story read aloud, the glucose drink did not reverse this decline. It appears that breakfast consumption influences cognition via several mechanisms, including an increase in blood glucose. PMID:9537627

    2015-01-01

    The advent of ambulatory blood pressure monitoring permitted examination of blood pressures during sleep and recognition of the associated circadian fall in pressure during this period. The fall in pressure,called the "dip",is defined as the difference between daytime mean systolic pressure and nighttime mean systolic pressure expressed as a percentage of the day value. Ten percent to 20% is considered normal. Dips less than 10%,referred to as blunted or absent,have been considered as predicting an adverse cardiovascular event. This view and the broader concept that white coat hypertension itself is a forerunner of essential hypertension is disputable. This editorial questions whether mean arterial pressures over many hours accurately represent the systolic load,whether nighttime dipping varies from measure to measure or is a fixed phenomenon,whether the abrupt morning pressure rise is a risk factor or whether none of these issues are as important as the actual night time systolic blood pressure itself. The paper discusses the difference between medicated and nonmedicated white coat hypertensives in regard to the cardiovascular risk and suggests that further work is necessary to consider whether the quality and duration of sleep are important factors.

  1. Regulation of pulpal blood flow

    International Nuclear Information System (INIS)

    The regulation of blood flow of the dental pulp was investigated in dogs and rats anesthetized with sodium pentobarbital. Pulpal blood flow was altered by variations of local and systemic hemodynamics. Macrocirculatory blood flow (ml/min/100 g) in the dental pulp was measured with both the 133Xe washout and the 15-microns radioisotope-labeled microsphere injection methods on the canine teeth of dogs, to provide a comparison of the two methods in the same tooth. Microcirculatory studies were conducted in the rat incisor tooth with microscopic determination of the vascular pattern, RBC velocity, and intravascular volumetric flow distribution. Pulpal resistance vessels have alpha- and beta-adrenergic receptors. Activation of alpha-receptors by intra-arterial injection of norepinephrine (NE) caused both a reduction in macrocirculatory Qp in dogs and decreases in arteriolar and venular diameters and intravascular volumetric flow (Qi) in rats. These responses were blocked by the alpha-antagonist PBZ. Activation of beta-receptors by intra-arterial injection of isoproterenal (ISO) caused a paradoxical reduction of Qp in dogs. In rats, ISO caused a transient increase in arteriolar Qi followed by a flow reduction; arteriolar dilation was accompanied by venular constriction. These macrocirculatory and microcirculatory responses to ISO were blocked by the alpha-antagonist propranolol

  6. Blood irradiation with accelerator produced electron beams

    International Nuclear Information System (INIS)

    Blood and blood products are irradiated with gamma rays to reduce the risk of graft versus host disease (GVHD). A simple technique using electron beams produced by a medical linear accelerator has been studied to evaluate irradiation of blood and blood products. Variations in applied doses for a single field 20 MeV electron beam are measured in a phantom study. Doses have been verified with ionization chambers and commercial diode detectors. Results show that the blood product volume can be given a relatively homogeneous dose to within 6% using 20 MeV electrons without the need to rotate the blood bags or the beam entry point. The irradiation process takes approximately 6.5 minutes for 30 Gy applied dose to complete as opposed to 12 minutes for a dual field x-ray field irradiation at our centre. Electron beams can be used to satisfactorily irradiate blood and blood products in a minimal amount of time. (author)

    NASA turbomachinery computer codes assisted in the design of the Cleveland Clinic Foundation's centrifugal bladed blood pump. The codes were originally developed for the aerospace industry, but are applicable to the blood pump because of a high degree of synergy with this application. Traditional turbomachinery design criteria were used in the design of the blood pump centrifugal impeller and volute casing. The fluid dynamic performance of the blood pump is meeting the engineering design goals of flow rate and pressure rise.

  9. Hospital billing for blood processing and transfusion for inpatient stays.

    Science.gov (United States)

    McCue, Michael J; Nayar, Preethy

    2009-07-01

    Medicare, an important payer for hospitals, reimburses hospitals for inpatient stays using Diagnosis Related Groups (DRGs). Many private insurers also use the DRG methodology to reimburse hospitals for their services. Therefore, those blood service organizations that bill Medicare directly require an understanding of the DRG system of payment to enable them to bill Medicare correctly, and in order to be certain they are adequately reimbursed. Blood centers that do not bill Medicare directly need to understand how hospitals are reimbursed for blood and blood components as this affects a hospital's ability to pay service fees related to these products. This review presents a detailed explanation of how hospitals are reimbursed by the Centers for Medicare and Medicaid Services (CMS) for Medicare inpatient services, including blood services.

  10. Uptake of carnitine by red blood cells

    Energy Technology Data Exchange (ETDEWEB)

    Campa, M.; Borum, P.

    1986-05-01

    A significant amount of blood carnitine (70% of cord blood and 40% of blood from healthy adults) is partitioned into the red blood cell compartment of whole blood. Data indicate that the plasma compartment and the red blood cell compartment of whole blood represent different metabolic pools of carnitine. There are no data to indicate that red blood cells synthesize carnitine, but our understanding of the uptake of carnitine by red blood cells is negligible. Red blood cells were obtained from healthy adults, washed twice with normal saline, and used for uptake experiments. When the cells were incubated at 37/sup 0/C in the presence of /sup 14/C-carnitine, radioactivity was found both in the soluble cytosolic and membrane fractions of the cells following lysis. The uptake was dependent upon the time of incubation, temperature of incubation, and carnitine concentration in the incubation medium. Washed red blood cell membranes incubated with /sup 14/C-carnitine showed specific binding of radioactivity. These data are consistent with the hypothesis that red blood cells have an uptake mechanism for L-carnitine.

    The Army Blood Program (ABP) is charged with the responsibility of supporting the Warfighter on the battlefield, in addition to meeting garrison hospital blood requirements on a daily basis. Blood support concepts developed in response to Operation Iraqi Freedom/Operation Enduring Freedom combat operations are the cornerstone to maintaining current capabilities and shaping future endeavors.. The ABP is actively engaged with research, advanced development of blood products and medical technology to improve blood safety and efficacy for both our conventional and operational forces. The feasibility of frozen/deglycerolized red blood cell use in theater has been demonstrated. The use of Blood Group A plasma in the place of Blood Group AB plasma has been successful. Placement of cryoprecipitate at Role 2 medical facilities and the placement of blood products on MEDEVAC (Vampire Program missions) have proven invaluable in moving transfusion therapy closer to the point of Injury. The improved patient outcomes from earlier transfusion of blood products has driven the requirement for far-forward blood support. Now (more than ever), there are products and processes in place to meet the requirements for blood use in the prehospital setting. PMID:27215865

  18. Relationship between blood groups and male infertility

    International Nuclear Information System (INIS)

    Background: Blood is man's complete and unchangeable identity. The ABO and Rh groups are recognised as major and clinically significant blood groups. Blood group antigens are not only important in relation to blood transfusion and organ transplantation, but also have been utilised in genetic research, anthropology and tracing ancestral relation of humans. The objective the present study is to examine the blood group antigens in infertile men for assessing the relationship to male infertility and to know the frequency of various blood groups among infertile males in our population. Method: A total of 1,521 patients along with 460 proven fathers as controls were recruited for the present study from both rural and urban areas of Pakistan and referred to Department of Reproductive Physiology/Health, Public Health Divisions, NIH, Islamabad, during 2002 to 2006. Blood grouping (ABO) and Rhesus factors (Rh) was done by the antigen antibody agglutination test. Results: Overall distribution of blood groups in the studied population of 1,521 subjects was 35.50%, 28.27%, 26.89% and 9.34% for blood groups O, B, A and AB respectively. The ratio of control to patient was 1:3.3. Conclusions: The present preliminary study revealed that in our population the prevalence of male infertility in blood group O is invariably higher than in all other ABO blood groups, showing a strong relationship between blood group O and male infertility.

  20. Prions and the blood and immune systems.

    Science.gov (United States)

    Mabbott, Neil; Turner, Marc

    2005-04-01

    Prion diseases take a number of forms in animals and humans. They are caused by conformational change in widely expressed prion protein leading to the formation of intracellular aggregates. Although the main focus of disease is the central nervous system, it is known that involvement of the immune system occurs in peripherally transmitted disease in particular. Animal experiments suggest that in some prion diseases follicular dendritic cells in the germinal centers are a major site of initial accumulation, and that abnormal prion protein and infectivity are detectable in peripheral lymphoid tissue from the earliest phase of disease. This raises the possibility that in a human peripherally transmitted prion disease like variant Creutzfeldt-Jakob disease, further transmission could occur through blood or tissue products or contamination of surgical instrumentation. Indeed two recent reports confirm that this disease has been transmitted by blood, raising significant public health concerns. PMID:15820951
