Umbilical cord blood is a valuable source of haematopoietic stem cells. There is little information about whether religious affiliations have any bearing on attitudes to and decisions about its collection, donation and storage. The authors provided information about umbilical cord blood banking to expert commentators from six major world religions (Catholicism, Anglicanism, Islam, Judaism, Hinduism and Buddhism) and asked them to address a specific set of questions in a commentary. The commentaries suggest there is considerable support for umbilical cord blood banking in these religions. Four commentaries provide moral grounds for favouring public donation over private storage. None attach any particular religious significance to the umbilical cord or to the blood within it, nor place restrictions on the ethnicity or religion of donors and recipients. Views on ownership of umbilical cord blood vary. The authors offer a series of general points for those who seek a better understanding of religious perspectives on umbilical cord blood banking.

Transfusion is a mechanism of transmission of Chagas' disease. There are no studies on the costs of the screening test in Colombian blood banks. To estimate the costs of the screening test for Chagas' disease among blood donors in two Colombian blood banks, 2015. We conducted a micro-costing study from the perspective of the health care provider to estimate the cost of Chagas' disease testing in two blood banks, Banco de Sangre de la Cruz Roja, Seccional Bolívar, and Banco de Sangre del Hospital de Yopal, Casanare, taking into account four cost categories: 1) Administrative costs: public services and insurance costs were calculated based on the blood bank area in square meters; 2) capital costs: building and equipment costs that were annualized using a 3% discount rate and a lifespan of 20 years for building and five for equipment; 3) costs of Chagas' disease test materials and reagents adjusted by blood bank production level, and 4) costs of staff in charge of Chagas' disease test processing. The costs of transfusion bagsand immunohematology tests are also reported. The cost of Chagas' disease test in the blood bank of Seccional Bolívar was COP$ 37,804 (USD$ 12), and the blood bag and immunohematology test costs were COP$ 25,941 (USD$ 8.2) and COP$ 6,800 (USD$ 2.2), respectively. In the blood bank of Yopal, Casanare, the costs were COP$ 77,384 (USD$ 24.6), COP$ 30,141 (USD$ 9.6) and COP$ 12,627 (USD$ 4), respectively. Personnel cost accounted for the highest percentage of the total cost for both blood banks (47.5% in Seccional Bolívar, and 55.7% in Yopal, Casanare). Our results are an important input for the planning of services and cost-effectiveness studies for screening tests for Chagas' disease in Colombian blood banks.

Efforts to implement family cord blood banking have been developed in the past decades for siblings requiring stem cell transplantation for conditions such as sickle cell disease. However, public banks are faced with challenging decisions about the units to be stored, discarded, or used for other endeavors. We report here 20 years of experience in family cord blood banking for sickle cell disease in two dedicated public banks. Participants were pregnant women who had a previous child diagnosed with homozygous sickle cell disease. Participation was voluntary and free of charge. All mothers underwent mandatory serological screening. Cord blood units were collected in different hospitals, but processed and stored in two public banks. A total of 338 units were stored for 302 families. Median recipient age was six years (11 months-15 years). Median collected volume and total nucleated cell count were 91 mL (range 23-230) and 8.6×10 8 (range 0.7-75×10 8 ), respectively. Microbial contamination was observed in 3.5% (n=12), positive hepatitis B serology in 25% (n=84), and homozygous sickle cell disease in 11% (n=37) of the collections. Forty-four units were HLA-identical to the intended recipient, and 28 units were released for transplantation either alone (n=23) or in combination with the bone marrow from the same donor (n=5), reflecting a utilization rate of 8%. Engraftment rate was 96% with 100% survival. Family cord blood banking yields good quality units for sibling transplantation. More comprehensive banking based on close collaboration among banks, clinical and transplant teams is recommended to optimize the use of these units. Copyright© Ferrata Storti Foundation.

Banks, regions and development

Full Text Available From the 1980s onwards the banking sectors in all the industrialised countries have been experiencing intense restructuring, aggregation and consolidation, radically changing their ownership structures and geography. Whatever the reasons behind such restructuring processes, the globalisation of the credit markets, the consolidation of banking structures, the removal of barriers to the free location of banks and their penetration of peripheral markets pose two main questions. Will integration of the banking systems lead to a narrowing or a widening of the development gap between regions? What relations will there be between financial centres and the periphery, and how will financial labour be divided between national (international banks and local (regional banks? The aim of this paper is to address such questions in the light of recent developments in the theoretical and empirical literature on financial integration.

Court upholds $405,000 award against blood banking industry.

Science.gov (United States)

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.

ACOG committee opinion number 399, February 2008: umbilical cord blood banking.

Science.gov (United States)

2008-02-01

Two types of banks have emerged for the collection and storage of umbilical cord blood--public banks and private banks. Public banks promote allogenic (related or unrelated) donation, analogous to the current collection of whole blood units in the United States. Private banks were initially developed to store stem cells from umbilical cord blood for autologous use (taken from an individual for subsequent use by the same individual) by a child if the child develops disease later in life. If a patient requests information on umbilical cord blood banking, balanced and accurate information regarding the advantages and disadvantages of public versus private banking should be provided. The remote chance of an autologous unit of umbilical cord blood being used for a child or a family member (approximately 1 in 2,700 individuals) should be disclosed. The collection should not alter routine practice for the timing of umbilical cord clamping. Physicians or other professionals who recruit pregnant women and their families for for-profit umbilical cord blood banking should disclose any financial interests or other potential conflicts of interest.

Cord blood is an important source of stem cells. However, nearly 90% of public cord blood banks have declared that they are struggling to maintain their financial sustainability and avoid bankruptcy. The objective of this study is to evaluate how characteristics of cord blood units influence their utilization, then use this information to model the economic viability and therapeutic value of different banking strategies. Retrospective analysis of cord blood data registered between January 1st, 2009 and December 31st, 2011 in Bone Marrow Donor Worldwide. Data were collected from four public banks in France, Germany and the USA. Samples were eligible for inclusion in the analysis if data on cord blood and maternal HLA typing and biological characteristics after processing were available (total nucleated and CD34+ cell counts). 9,396 banked cord blood units were analyzed, of which 5,815 were Caucasian in origin. A multivariate logistic regression model assessed the influence of three parameters on the CBU utilization rate: ethnic background, total nucleated and CD34+ cell counts. From this model, we elaborated a Utilization Score reflecting the probability of transplantation for each cord blood unit. We stratified three Utilization Score thresholds representing four different banking strategies, from the least selective (scenario A) to the most selective (scenario D). We measured the cost-effectiveness ratio for each strategy by comparing performance in terms of number of transplanted cord blood units and level of financial deficit. When comparing inputs and outputs over three years, Scenario A represented the most extreme case as it delivered the highest therapeutic value for patients (284 CBUs transplanted) along with the highest financial deficit (USD 5.89 million). We found that scenario C resulted in 219 CBUs transplanted with a limited deficit (USD 0.98 million) that charities and public health could realistically finance over the long term. We also found that

In this study, a self-administered questionnaire was used to assess opinions about stem cell research and cord blood banking. Three attitudes were examined: willingness to accept cord blood banking, willingness to accept embryonic stem cell research, and religious belief system. A total of 90 Wayne State University students enrolled in the study in response to an invitation posted on a web page for the university. Sex distribution among study participants was 79 females and eight males; three declined to state their sex. Support for cord blood banking was high (> 70%) among students. Students over the age of 25 years of age were more (85%) positive than students 18 to 24 years old (57%). They prefered a public cord blood bank over a private cord blood bank. Atheist/agnostic or spiritual/not religious students (> 90%), Catholic students (78%) and Christian students (58%) support cord blood banking. Age, sex and religion seems influence the student's attitude towards stem cell research and cord blood banking.

Objective Private cord blood banks are for-profit companies that facilitate storage of umbilical cord blood for personal or family use. Pediatric hematopoietic cell transplantation (HCT) physicians are currently best situated to use cord blood therapeutically. We sought to describe the experiences and views of these physicians regarding private cord blood banking. Participants and Methods Emailed cross-sectional survey of pediatric HCT physicians in the United States and Canada. 93/152 potentially eligible physicians (93/130 confirmed survey recipients) from 57 centers responded. Questions addressed the number of transplants performed using privately banked cord blood, willingness to use banked autologous cord blood in specific clinical settings, and recommendations to parents regarding private cord blood banking. Results Respondents reported having performed 9 autologous and 41 allogeneic transplants using privately banked cord blood. In 36/40 allogeneic cases for which data were available, the cord blood had been collected because of a known indication in the recipient. Few respondents would choose autologous cord blood over alternative stem cell sources for treatment of acute lymphoblastic leukemia in second remission. In contrast, 55% would choose autologous cord blood to treat high-risk neuroblastoma, or to treat severe aplastic anemia in the absence of an available sibling donor. No respondent would recommend private cord blood banking for a newborn with one healthy sibling when both parents were of Northern European descent; 11% would recommend banking when parents were of different minority ethnicities. Conclusions Few transplants have been performed using cord blood stored in the absence of a known indication in the recipient. Willingness to use banked autologous cord blood varies depending on disease and availability of alternative stem cell sources. Few pediatric HCT physicians endorse private cord blood banking in the absence of an identified recipient

A variety of financing mechanisms and managerial innovations have been developed in the past decade to control hospital costs. Some evidence suggests that those changes have not produced substantial improvements in labor efficiency among employees in the hospital's technical level, such as in the blood bank laboratories. This study measured labor efficiency in 40 hospital-based blood bank laboratories in Southern California during the year from July 1989 to June 1990 and explored the impact of financial, managerial, and operational factors on labor efficiency. With standardized output measures used in all blood bank laboratories, a wide variation of labor efficiency was found. Multivariate analyses indicate that the labor efficiency of blood bank employees was not influenced by organizational financial incentives, but was affected by the managerial styles of blood bank managers. Interpretation of the findings suggests that labor efficiency is affected by operational designs intended to improve responses to variable workloads and reduce slack time.

Optimization of informed consent for umbilical cord blood banking.

Sugarman, Jeremy; Kurtzberg, Joanne; Box, Tamara L; Horner, Ronnie D

2002-12-01

The purpose of this project was to evaluate the informed consent process for donation to a public umbilical cord blood bank. Telephone interviews were conducted with 170 women who had given consent to donate their newborn infants' umbilical cord blood. Of the 170 women who were contacted, 96.8% of the women reported that all their questions had been answered. Nevertheless, approximately one third of the respondents did not consider themselves to be in research, and almost one quarter of the respondents did not know how to contact the umbilical cord blood bank if they or their infant became seriously ill. Further, a substantial proportion of the respondents did not understand the full range of alternatives to donation and incorrectly endorsed potential benefits. Informed consent could be optimized by (1) having those personnel who obtain consent emphasize that banking involves research and to explain the true benefits of donation, (2) ensuring that parents know how and when to contact the umbilical cord blood bank after donation, and (3) using phone surveys to continue assessments and to monitor changes in the process.

Cord blood has moved rapidly from an experimental stem cell source to an accepted and important source of hematopoietic stem cells. There has been no comprehensive assessment of US public cord blood banking practices since the Institute of Medicine study in 2005. Of 34 US public cord blood banks identified, 16 participated in our qualitative survey of public cord blood banking practices. Participants took part in in-depth telephone interviews in which they were asked structured and open-ended questions regarding recruitment, donation, and the informed consent process at these banks. Thirteen of 16 participants reported a variably high percentage of women who consented to public cord blood donation. Fifteen banks offered donor registration at the time of hospital admission for labor and delivery. Seven obtained full informed consent and medical history during early labor and eight conducted some form of phased consent and/or phased medical screening and history. Nine participants identified initial selection of the collection site location as the chief mode by which they recruited minority donors. Since 2005, more public banks offer cord blood donor registration at the time of admission for labor and delivery. That and the targeted location of cord blood collection sites are the main methods used to increase access to donation and HLA diversity of banked units. Currently, the ability to collect and process donations, rather than donor willingness, is the major barrier to public cord blood banking. © 2012 American Association of Blood Banks.

This paper reports the performance of particle swarm optimization (PSO) for the assignment of blood to meet patients' blood transfusion requests for blood transfusion. While the drive for blood donation lingers, there is need for effective and efficient management of available blood in blood banking systems. Moreover, inherent danger of transfusing wrong blood types to patients, unnecessary importation of blood units from external sources, and wastage of blood products due to nonusage necessitate the development of mathematical models and techniques for effective handling of blood distribution among available blood types in order to minimize wastages and importation from external sources. This gives rise to the blood assignment problem (BAP) introduced recently in literature. We propose a queue and multiple knapsack models with PSO-based solution to address this challenge. Simulation is based on sets of randomly generated data that mimic real-world population distribution of blood types. Results obtained show the efficiency of the proposed algorithm for BAP with no blood units wasted and very low importation, where necessary, from outside the blood bank. The result therefore can serve as a benchmark and basis for decision support tools for real-life deployment. PMID:25815046

Human term placenta is comprised of various tissues from which different cell populations can be obtained, including hematopoietic stem cells and mesenchymal stem/stromal cells (MSCs). Areas covered: This review will discuss the possibility to incorporate placental tissue cells in cord blood banking. It will discuss general features of human placenta, with a brief review of the immune cells at the fetal-maternal interface and the different cell populations isolated from placenta, with a particular focus on MSCs. It will address the question as to why placenta-derived MSCs should be banked with their hematopoietic counterparts. It will discuss clinical trials which are studying safety and efficacy of placenta tissue-derived MSCs in selected diseases, and preclinical studies which have proven their therapeutic properties in other diseases. It will discuss banking of umbilical cord blood and raise several issues for improvement, and the applications of cord blood cells in non-malignant disorders. Expert Commentary: Umbilical cord blood banking saves lives worldwide. The concomitant banking of non-hematopoietic cells from placenta, which could be applied therapeutically in the future, alone or in combination to their hematopoietic counterparts, could exploit current banking processes while laying the foundation for clinical trials exploring placenta-derived cell therapies in regenerative medicine.

Analyses of Blood Bank Efficiency, Cost-Effectiveness and Quality

Science.gov (United States)

Lam, Hwai-Tai Chen

In view of the increasing costs of hospital care, it is essential to investigate methods to improve the labor efficiency and the cost-effectiveness of the hospital technical core in order to control costs while maintaining the quality of care. This study was conducted to develop indices to measure efficiency, cost-effectiveness, and the quality of blood banks; to identify factors associated with efficiency, cost-effectiveness, and quality; and to generate strategies to improve blood bank labor efficiency and cost-effectiveness. Indices developed in this study for labor efficiency and cost-effectiveness were not affected by patient case mix and illness severity. Factors that were associated with labor efficiency were identified as managerial styles, and organizational designs that balance workload and labor resources. Medical directors' managerial involvement was not associated with labor efficiency, but their continuing education and specialty in blood bank were found to reduce the performance of unnecessary tests. Surprisingly, performing unnecessary tests had no association with labor efficiency. This suggested the existence of labor slack in blood banks. Cost -effectiveness was associated with workers' benefits, wages, and the production of high-end transfusion products by hospital-based donor rooms. Quality indices used in this study included autologous transfusion rates, platelet transfusion rates, and the check points available in an error-control system. Because the autologous transfusion rate was related to patient case mix, severity of illness, and possible inappropriate transfusion, it was not recommended to be used for quality index. Platelet-pheresis transfusion rates were associated with the transfusion preferences of the blood bank medical directors. The total number of check points in an error -control system was negatively associated with government ownership and workers' experience. Recommendations for improving labor efficiency and cost

This study explores pregnant women's awareness of cord blood stem cells and their attitude regarding banking options in France, Germany, Italy, Spain, and the UK. Questionnaires were distributed in six maternities. This anonymous and self-completed questionnaire included 29 multiple-choice questions based on: 1) sociodemographic factors, 2) awareness and access to information about cord blood banking, 3) banking option preferences, and 4) donating cord blood units (CBUs) to research. A total of 79% of pregnant women had little awareness of cord blood banking (n = 1620). A total of 58% of women had heard of the therapeutic benefits of cord blood, of which 21% received information from midwives and obstetricians. A total of 89% of respondents would opt to store CBUs. Among them, 76% would choose to donate CBUs to a public bank to benefit any patient in need of a cord blood transplant. Twelve percent would choose a mixed bank, and 12%, a private bank. A total of 92% would donate their child's CBU to research when it is not suitable for transplantation. The study reveals a strong preference for public banking in all five countries, based on converging values such as solidarity. Attitudes of pregnant women are not an obstacle to the rapid expansion of allogeneic banking in these EU countries. Banking choices do not appear to be correlated with household income. The extent of commercial marketing of cord blood banks in mass media highlights the importance for obstetric providers to play a central role in raising women's awareness early during their pregnancy with evidence-based medical information about banking options. © 2010 American Association of Blood Banks.

Full Text Available This study aimed to analyze the bank rating in terms of differences the financial performance between the Regional Development Banks and Non-Foreign Exchange Commercial Banks. It is consist of capital adequacy asset quality profitability Return On Asset ROA Return on Equity ROE Net Interest Margin NIM and Liquidity Loan to Deposit Ratio. The fulfillment of capital adequacy and asset quality of the bank groups did not differed significantly while in terms of profitability and liquidity there are significant differences. The earning difference is more likely due to the Regional Development Banks sources of funds for the implementation of the Local Government Cash Holder function as the Provincial Government and District City. The difference of liquidity are showed by the performance of Regional Development Banks and the Non-Foreign Exchange Commercial Banks in lendingfinancing whereas the two groups of banks on average are still relatively low in lending.

Umbilical cord blood is used as a source of hematopoietic stem cells for bone marrow transplantation in the treatment of malignant and nonmalignant disease. We sought to examine pregnant women's knowledge and attitudes regarding cord blood banking, as their support is crucial to the success of cord blood transplant programs. A questionnaire examining sociodemographic factors and women's attitudes to cord blood banking was developed on the basis of findings from 2 focus groups and a pilot study. The questionnaire was distributed to 650 women attending antenatal clinics at a regional women's hospital between April and July 2001. A total of 443 women (68%) responded. More than half of the women (307/438 or 70% [95% confidence interval, CI, 66% to 74%]) reported poor or very poor knowledge about cord blood banking. Many of the respondents (299/441 or 68% [95% CI 63% to 72%]) thought that physicians should talk to pregnant women about the collection of cord blood, and they wanted to receive information about this topic from health care professionals (290/441 or 66% [95% CI 61% to 70%]) or prenatal classes (308/441 or 70% [95% CI 65% to 74%]). Most of the women (379/442 or 86% [95% CI 82% to 89%]) would elect to store cord blood in a public bank, many citing altruism as the reason for this choice. A much smaller proportion (63/442 or 14% [95% CI 11% to 18%]) would elect private banking, indicating that this would be a good investment or that they would feel guilty if the blood had not been stored. Additional acceptable uses for cord blood included research (mentioned by 294/436 women or 67% [95% CI 63% to 72%]) and gene therapy (mentioned by 169/437 women or 39% [95% CI 34% to 43%]). Most of the women in this study supported the donation of cord blood to public cord blood banks for potential transplantation and research.

Can routine commercial cord blood banking be scientifically and ethically justified?

Full Text Available BACKGROUND TO THE DEBATE: Umbilical cord blood--the blood that remains in the placenta after birth--can be collected and stored frozen for years. A well-accepted use of cord blood is as an alternative to bone marrow as a source of hematopoietic stem cells for allogeneic transplantation to siblings or to unrelated recipients; women can donate cord blood for unrelated recipients to public banks. However, private banks are now open that offer expectant parents the option to pay a fee for the chance to store cord blood for possible future use by that same child (autologous transplantation.

Full Text Available Platelet transfusions are vital for the prevention of fatal hemorrhage. Therefore, a stable inventory of platelets is required for an efficient and effective delivery of services in all the hospitals and medical centers. However, over the past decades, the requirement for platelets seems to be continuously increasing, while the number of potential donors is decreasing. Moreover, due to its very short life span of just five days, a large volume of platelets expires while they are on the shelves, resulting unnecessary shortages of platelets. Furthermore, it is very costly and difficult to get platelets from another blood bank in a short notice. Hence, these unexpected shortages put the life of patients at risk. This study is focused on addressing the issues discussed, by developing an efficient blood inventory management model to reduce the platelet shortages, and wastages, while reducing the related inventory costs. Currently, the blood banks are managing platelet inventory according to their own instincts, which result to shortages and wastages. As a solution, we propose a model to manage the daily supply of platelets by forecasting the daily demand. Three different algorithms were developed using lower bound, average and upper bound values and tested to find the optimal solution that best fits to manage platelet inventory. These models were tested using data for 60 days obtained from two different levels of blood banks in Sri Lanka, namely a General Hospital blood bank and a Base Hospital blood bank. In General hospitals, the demand for blood components including platelets is very high when compared to the Base hospitals. The study was able to come up with two different inventory management models for the two different types of blood banks. The model that best fits the General Hospital blood bank where the demand is high and was able to reduce the shortages by 46.74%, wastage by 89.82% and total inventory level by 39.10% and, the model that

The status of Chagas' disease in Ecuador is not clear. In response to reports suggesting the possibility of transfusion-associated transmission of Chagas' disease in the blood bank in Quito, the Ecuadorian Red Cross in collaboration with the Instituto Nacional de Higiene, Zona Norte and the Tropical Disease Institute of Ohio University implemented a pilot Chagas' disease screening of the donated blood in the Quito blood bank. The results of the screening showed a low incidence of seropositivity among the donors (0.01% in 1994, 0.04% in 1995, and 0.02% in 1996) to the Quito blood bank and a higher seropositivity in samples donated to smaller blood banks (0.4% in 1994, 0.28% in 1995, and 0.13% in 1996) located in areas considered endemic, as well as from at least two areas previously considered nonendemic for Chagas' disease. This report highlights the need for a comprehensive evaluation of the prevalence and distribution of Chagas' disease in Ecuador.

We studied proteolytic alterations of membrane proteins in ghosts derived from human red blood cells, preserved up to 35 days in the liquid state either as whole blood or with additive solution. The study was carried out by performing sodium dodecyl sulfate polyacrylamide gel electrophoresis of stromal proteins from erythrocytes, either previously treated with proteinase inhibitors or previously incubated in conditions promoting proteolysis. To differentiate the effect of erythrocyte from granulocyte proteinases, the investigation was also carried out in leukocyte-free red cell preparations. The results show: (1) the effects of endogenous proteinases on membrane proteins derived from red cells stored under blood bank conditions; (2) a decrease of proteolytic effects in ghosts derived from red cells which have been submitted to a longer storage; (3) a relevant influence of the red cell resuspending medium before lysis on the time-dependent onset and exhaustion of proteolysis in ghosts. The presence of increased proteolysis in ghosts could be regarded as a marker of molecular lesions induced in red cells by storage under blood bank conditions.

Cord Blood Banking Standards: Autologous Versus Altruistic.

Science.gov (United States)

Armitage, Sue

2015-01-01

Cord blood (CB) is either donated to public CB banks for use by any patient worldwide for whom it is a match or stored in a private bank for potential autologous or family use. It is a unique cell product that has potential for treating life-threatening diseases. The majority of CB products used today are for hematopoietic stem cell transplantation and are accessed from public banks. CB is still evolving as a hematopoietic stem cell source, developing as a source for cellular immunotherapy products, such as natural killer, dendritic, and T-cells, and fast emerging as a non-hematopoietic stem cell source in the field of regenerative medicine. This review explores the regulations, standards, and accreditation schemes that are currently available nationally and internationally for public and private CB banking. Currently, most of private banking is under regulated as compared to public banking. Regulations and standards were initially developed to address the public arena. Early responses from the medical field regarding private CB banking was that at the present time, because of insufficient scientific data to support autologous banking and given the difficulty of making an accurate estimate of the need for autologous transplantation, private storage of CB as "biological insurance" should be discouraged (1, 2, 3). To ensure success and the true realization of the full potential of CB, whether for autologous or allogeneic use, it is essential that each and every product provided for current and future treatments meets high-quality, international standards.

Whatever the reasons behind such restructuring processes, the globalisation of the credit markets, the consolidation of banking structures, the removal of barriers to the free location of banks and their penetration of peripheral markets pose two main questions. Will integration of the banking systems lead to a narrowing or a widening of the development gap between regions? What relations will there be between financial centres and the periphery, and how will financial labour be divided between national (international banks and local (regional banks?

The existence and sustenance of the blood bank depends on blood donors. It is imperative that the donation experience is satisfactory for the donors. Therefore this study was carried out to determine the frequency of undesirable events experienced by the blood donor as part of donor haemovigilance. This was a retrospective descriptive study of the events that occurred amongst the blood donors of the blood bank of a tertiary institution. The blood donor incident book was reviewed for the period of six months. Negative undesirable events occurred in 2% of the donor populations, of which 45.8% could not complete the blood donation process while only 16.7% completed the blood donation process. Mild vasovagal attack occurred in 0.2% of the donor population. Undisclosed deferrable risk factors/ behaviours were identified by the phlebotomist in the bleeding room which made donors unfit for donation even though they had passed the donor screening criteria. This accounted for 20.8% of those with negative experience. Guidelines are required to identify donors that are not likely to complete donation to avoid wastage of time, blood, resources and reduce undesirable experiences.

A good blood bank must be able to provide compatible blood units promptly to operating room patients with minimal wastage. A "self-service" by nursing staff blood banking system that is safe, efficient, and well-accepted has been developed. Specific blood units are no longer assigned to surgical patients who have a negative pretransfusion antibody screen, irrespective of the type of surgery. A computer-generated list of the serial numbers of all group-identical blood units currently in the blood bank inventory is provided for each patient. The units themselves are not labeled with a patient's name. The group O list will be provided for group O patients, the group A list for group A patients, and so forth. Should the patient require transfusion during surgery, the operating room nurses go to the refrigerator, remove any group-identical unit, and check the serial number of the unit against the serial numbers on the patient's list. If the serial number is on that list, the blood bank will accept responsibility for compatibility. The system was implemented in 1995. Since implementation, a total of 2154 patients have undergone operations at this hospital. Thirty-two patients received more than 10 units of red cells each. There were no transfusion errors. The crossmatch-to-transfusion ratio was reduced from 1.67 to 1.12. Turnaround time for supplying additional or urgent units to patients in operating room was shortened from 33 to 2.5 minutes. There was no incidence of a blood unit's serial number not being on the list. Work by nurses and technical staff was reduced by nearly 50 percent. The "self-service" (by nursing staff) blood banking system described is safe and efficient. It saves staff time and can be easily set up.

Collateral Determinats In Bank Risk Mananagement: The Regional Case

Full Text Available Regional banks are struggling with significant obstacles in the modern Russian economy. Among them are strong competition with major big banks, strong resource restrictions, tightening the Bank of Russia’s requirements, and quite rapid expansion of financial technologies. Thus, the reduction of regional banks occurs, that produces both a negative impact on the development of small and medium enterprises (SMEs and challenges for balanced competition on the Russian market. Basically, these banks provide the settlement of region’s social and economic problems while maintaining local companies and enterprises. Collateral, as a source for losses covering, became the essential element of credit risk management in banks. Providing lenders to implement such instruments, it helps to reduce bank losses under borrower’s default. The purpose of the article relates to revealing of collateral determinants with higher impact on bank risk with the application of empirical methods (including regional level. This study is based on linear regression models evaluated by the least square method. Private data of secured small and medium business loans is used. This article presents LTV (loan-to-value as a major collateral determinant. The empirical evidence of interlinkage between collateral requirements, by the means of LTV, and risk premium is provided for loan portfolio of Russian regional banks. The hypothesis that LTV conversely correlates with risk premium is statistically proved.

Public cord blood banks are a source of hematopoietic stem cells for patients with hematological diseases who lack a family donor and need allogeneic transplantation. In June 2007 we started a cord blood bank with units donated in three maternity wards in Santiago, Chile. We report the first three transplants done with cord blood units form this bank. Cord blood units were obtained by intrauterine collection at delivery. They were depleted of plasma and red cells and frozen in liquid nitrogen. Tests for total nucleated cells, CD34 cell content, viral serology, bacterial cultures and HLA A, B and DRB1 were done. Six hundred cord blood units were stored by March 2012. Three patients received allogeneic transplant with cord blood from our bank, two with high risk lymphoblastic leukemia and one with severe congenital anemia. They received conditioning regimens according to their disease and usual supportive care for unrelated donor transplantation until full hematopoietic and immune reconstitution was achieved. The three patients had early engraftment of neutrophils and platelets. The child corrected his anemia and the leukemia patients remain in complete remission. The post-transplant course was complicated with Epstein Barr virus, cytomegalovirus and BK virus infection. Two patients are fully functional 24 and 33 months after transplant, the third is still receiving immunosuppression.

To provide information for umbilical cord blood (UCB) banks to adopt optimal collection strategies and to make UCB banks operate efficiently, we investigated the reasons for exclusion of UCB units in a 3-year recruitment period. We analyzed records of the reasons for exclusion of the potential UCB donation from 2004 to 2006 in the Tzu-Chi Cord Blood Bank and compared the results over 3 years. We grouped these reasons for exclusion into five phases, before collection, during delivery, before processing, during processing, and after freezing according to the time sequence and analyzed the reasons at each phase. Between 2004 and 2006, there were 10,685 deliveries with the intention of UCB donation. In total, 41.2% of the UCB units were considered eligible for transplantation. The exclusion rates were 93.1, 48.4, and 54.1% in 2004, 2005, and 2006, respectively. We excluded 612 donations from women before their child birth, 133 UCB units during delivery, 80 units before processing, 5010 units during processing, and 421 units after freezing. There were 24 UCB units with unknown reasons of ineligibility. Low UCB weight and low cell count were the first two leading causes of exclusion (48.6 and 30.9%). The prevalence of artificial errors, holiday or transportation problem, low weight, and infant problems decreased year after year. The exclusion rate was high at the beginning of our study as in previous studies. Understanding the reasons for UCB exclusion may help to improve the efficiency of UCB banking programs in the future. © 2013 American Association of Blood Banks.

Recent evidence has suggested that phosphoinositides play a significant role in maintaining membrane structure and function. Their importance during blood bank storage is not understood. They have performed preliminary studies of the phosphoinositide synthetic pathway enzymes of RBC during blood bank storage. At 0 and 35 days of storage leaky ghosts were prepared and incubated with [γ- 32 P]ATP for 5 minutes at 30 C. One aliquot was subjected to acidified solvent extraction and thin layer chromatography. The labeled phosphoinositide -4,5 biphosphate (PIP 2 ), phosphoinositide-4 phosphate (PIP) and phosphatidic acid (PA) spots were scraped and counted by liquid scintillation spectrometry. Another aliquot was used for SDS-PAGE and the radioactivity associated with the β-spectrin was measured. These experiments suggest a decrease in RBC phosphoinositol and PIP-Kinases and β-spectrin kinase activities during blood bank storage. Further studies are being done to evaluate significance of these observations

Full Text Available The article presents the results of the research of the methodological and information infrastructure of the integrated risk management in a regional commercial bank. Within the study of the general development tendencies of the regional banking services market, the most significant risks for a regional bank are revealed. The analysis is carried out on the basis of the stress testing technique developed at the Plekhanov Russian University of Economics. It is based on a technique of dynamic economic and mathematical modeling with the application of information technologies. The created combination of the methodological and instrumental tools allows to carry out the dynamic scenario analysis of the activity of a commercial bank for the identification of potential risks and for the development of the strategy of financial management reducing the potential risks and leveling the consequences of their realization. The received tool allows during the computer test to watch the predicted dynamics of the condition of the key indicators of the activity of a regional commercial bank changing under the influence of the exogenous regulatory measures and instruments of bank management applied to decrease risk and at the same time to introduce adjustments in the perspective strategy of management. As the result of the analysis, the universal management model of the main bank risks in a regional commercial bank within three alternative scenarios is created. The software product allowing to develop and acquire the practical skills of the students in banking is developed. It also may help to develop the methodological support for the regulation of the organizational procedures of risk management in a regional commercial bank. The received software product may be used in a system of the improving the professional skills, and also for obtaining the expected data in a risk management system in a regional commercial bank.

This report aims to clarify the position of the hospital blood bank in the light of product liability legislation contained in the Consumer Protection Act of 1987. Blood has been defined a 'product' under this Act. The potential for the blood bank to be seen in the role of 'supplier', 'keeper' or even 'producer' in the chain of product supply to the patient is explained and advice given on the resulting implications for blood bank practice. It will be necessary to define, adopt and implement standard operating procedures (SOP) for all blood bank activities. Guidance is given on the format, preparation and content of SOPs and specimen examples offered. The fundamental importance of quality assurance is emphasized.

Internal quality control (IQC) is the backbone of quality assurance program. In blood banking, the quality control of blood products ensures the timely availability of a blood component of high quality with maximum efficacy and minimal risk to potential recipients. The main objective of this study is to analyze the IQC of blood products as an indicator of our blood bank performance. An observational cross-sectional study was conducted at the blood bank of Liaquat National Hospital and Medical College, from January 2014 to December 2015. A total of 100 units of each blood components were arbitrarily chosen during the study. Packed red cell units were evaluated for hematocrit (HCT); random platelet concentrates were evaluated for pH, yield, and culture; fresh frozen plasma (FFP) and cryoprecipitate (CP) were evaluated for unit volume, factor VIII, and fibrinogen concentrations. A total of 400 units were tested for IQC. The mean HCT of packed red cells was 69.5 ± 7.24, and in 98% units, it met the standard (<80% of HCT). The mean platelet yield was 8.8 ± 3.40 × 10 9 /L and pH was ≥6.2 in 98% bags; cultures were negative in 97% of units tested. Mean factor VIII and fibrinogen levels were found to be 84.24 ± 15.01 and 247.17 ± 49.69 for FFP, respectively. For CP, mean factor VIII and fibrinogen level were found to be 178.75 ± 86.30 and 420.7 ± 75.32, respectively. The IQC of blood products at our blood bank is in overall compliance and met recommended international standards. Implementation of standard operating procedures, accomplishment of standard guidelines, proper documentation with regular audit, and staff competencies can improve the quality performance of the transfusion services.

In Italy, the law does not permit the setting up of private banks to preserve cord blood (CB) stem cells for personal use. However, since 2007 the right to export and preserve them in private laboratories located outside Italy has existed, and an increasing number of women are requesting this collection of umbilical CB at delivery to enable storage of stem cells for autologous use. Since private banks recruit clients mainly via the Internet, we examined the content of 24 Italian-language websites that offer stem cells storage (from CB or amniotic fluid), to assess what information is available. We found that the majority of private banks give no clear information about the procedures of collection, processing, and banking of CB units and that the standards offered by private CB banks strongly differ in terms of exclusion or acceptance criteria from the public banks. These factors may well influence the overall quality of the CB units stored in private CB banks. Of note, during the period 2007 to 2009, the number collected for autologous use did not create a downward trend on the number of units stored in public CB banks for allogeneic use. CB is a valuable community resource but expectant parents should be better informed as to the quality variables necessary for its storage, both by institutions and by professionals. Currently, most of the advertising is insufficient to justify the expense and the hopes pinned on autologous use of CB stem cells. © 2011 American Association of Blood Banks.

Stem cell transplantation and cord blood banking have received much popularity among general public and medical professionals in the recent past. But information about the scientific aspects, its utility and limitations is incomplete amongst laypersons as well as many medical practitioners. Stem cells differ from all other types of cells in the human body because of their ability to multiply in order to self perpetuate and differentiate into specialized cells. Stems cells could be totipotent, multipotent, pluripotent, oligopotent or unipotent depending on the type of cells that can arise or differentiate from them. Umbilical cord blood serves as a potent source of hematopoeitic stem cells and is being used to treat various disorders like blood cancers, hemoglobinopathies and immunodeficiency disorders for which hematological stem cell transplantation is the standard of care. Cord blood can be collected at ease, without any major complications and has a lower incidence of graft vs. host reaction compared to bone marrow cells or peripheral blood cells. Both public and private banks have been established for collection and storage of umbilical cord blood. However, false claims and misleading commercial advertisements about the use of umbilical cord blood stem cells for the treatment of a variety of conditions ranging from neuromuscular disorders to cosmetic benefits are widespread and create unrealistic expectations in laypersons and clinicians. Many clinicians and laypersons are unaware of the limitations of cord blood banking, as in treating a genetic disorder by autologous cord blood transplant. Knowledge and awareness about the scientific indications of cord blood stem cell transplantation and realistic expectations about the utility of cord blood among medical practitioners are essential for providing accurate information to laypersons before they decide to preserve umbilical cord blood in private banks and thus prevent malpractice.

Full Text Available Since the success of the first umbilical cord blood (UCB transplantation in a child with Fanconi anaemia in 1989, great interests have emerged for this source of stem cells. UCB provides an unlimited source of ethnically diverse stem cells and is an alternative for bone marrow (BM and peripheral blood (PB heamatopoietic stem cell transplantation (HSCT. Thus, UCB and manipulated stem cells are now collected and banked according to international accreditation standards for listing on registries allowing rapid search and accessibility worldwide. This work aims to identify problems limiting the creation of a Moroccan cord blood bank and to highlight opportunities and issues of a new legislation promoting additional applications of cell therapy.

Umbilical cord blood (UCB) is an important source of hematopoietic stem cells for transplantation especially in minority populations with limited chances of finding a histocompatible volunteer donor in the registry. UCB has the advantages of early availability, successful outcomes despite some histocompatibility mismatch, and low incidence of chronic graft-versus-host disease. Public cord blood banks that disseminate UCB products for transplant depend on voluntary donation at participating hospitals and obstetrical providers for collection. Using survey questionnaires, we evaluated attitudes toward UCB donation, the frequency of donation, and provider opinions on UCB collection in the greater St. Louis metropolitan area that caters to minority ethnicities in significant numbers. Our data suggest that nervousness and lack of information regarding the donation and utility of the product were ubiquitous reasons for not donating. Additionally, irrespective of age or level of education, women relied on healthcare providers for information regarding UCB donation. Providers reported primarily time constraints to discussing UCB donation at prenatal visits (54%). Of the interviewees, 62% donated UCB. Fallout due to refusal or preferring private banking was miniscule. These results suggest that dedicated personnel focused on disseminating information, obtaining consent, and collecting the UCB product at major hospitals can enrich cord blood banks especially with minority cords. Sustained and focused efforts could improve upon a relatively high wastage rate and ensure a robust supply of UCB products at local public banks. © 2017 Wiley Periodicals, Inc.

This study was to determine pregnant women's knowledge and attitudes towards stem cells and cord blood banking in Istanbul, Turkey. Stem cell research is one of the most important and, at the same time, the most controversial topics of science and technology today. Nurses need to understand stem cell research so they can enter the debate on this issue. They can become important sources of information in order to help parents understand the issues. This exploratory descriptive study was conducted in two antenatal outpatient clinics in Istanbul. The sample consisted of 334 pregnant women during routine prenatal visits. Data were collected in interviews by using an interview form developed by the researchers according to the literature. The form included demographic characteristics of participants and 20 questions about stem cells, storing cord blood and banking and 10 independent attitude statements. The majority of the participants had a lack of knowledge about stem cells and cord blood banking and wanted more information. Before pregnancy, they received some information through the media (newspaper, Internet, television, etc.), but unintentionally. It was determined that they wanted information before becoming pregnant, more from their obstetrician but also from nurses and midwives. The majority also wanted to store their infants' cord blood and stated that they would be more likely to choose a public cord blood bank. Those giving ante- and perinatal care need to offer accurate and scientific counselling services on this subject to parents who need to be informed.

Full Text Available Background: Nucleic acid amplification testing (NAT is restricted to a few blood banks in India since 2008. This review was directed toward understanding NAT yield in different parts of the country and prevalence in the NAT of different types of virus. Materials and Methods: English literature was searched from 1990 to 2016 in PubMed, Scopus, Ind med, and Google database using properly constructed key words. Literature was collected and finally the data were synthesized. Results: NAT results from 11 publications and one personal communication showed that till date 389387 blood units have been NAT tested from various parts of the country. NAT yield varied from 1:476 to 1:4403 in various studies. Till date, 58/2550 (2% blood banks of India are doing NAT testing but all of them have not published their results. Majority of the centers have used ID-NAT (Individual NAT protocol and 21 blood banks are using minipool format of the test. One center has used in-house NAT testing system. In> 70% of the time, the NAT positivity with due to hepatitis B (Hep B. For individual infection, NAT yield from the pooled data showed HIV in 1:66,000, Hep C virus 1:5484 and Hep B in 1:1761 seronegative donors. Discussion and Conclusion: In view of the very high NAT yield (1:1361, NAT in some from needs to be universally applied in Indian blood banks. However, the high Hep B occult infection suggests stricter donor selection and immunization of adults for Hep B may be way forward toward ensuring the viral safety of blood components in India.

Summary Population aging has imposed cost-effective alternatives to blood donations. Artificial blood is still at the preliminary stages of development, and the need for viable cells seems unsurmountable. Because large numbers of viable cells must be promptly available for clinical use, stem cell technologies, expansion, and banking represent ideal tools to ensure a regular supply. Provided key donors can be identified, induced pluripotent stem cell (iPSC) technology could pave the way to a new era in transfusion medicine, just as it is already doing in many other fields of medicine. The present review summarizes the current state of research on iPSC technology in the field of blood banking, highlighting hurdles, and promises. Significance The aging population in Western countries is causing a progressive reduction of blood donors and a constant increase of blood recipients. Because blood is the main therapeutic option to treat acute hemorrhage, cost-effective alternatives to blood donations are being actively investigated. The enormous replication capability of induced pluripotent stem cells and their promising results in many other fields of medicine could be an apt solution to produce the large numbers of viable cells required in transfusion and usher in a new era in transfusion medicine. The present report describes the potentiality, technological hurdles, and promises of induced pluripotent stem cells to generate red blood cells by redifferentiation. PMID:26819256

Cord blood banking - bio-objects on the borderlands between community and immunity.

Brown, Nik; Williams, Rosalind

2015-01-01

Umbilical cord blood (UCB) has become the focus of intense efforts to collect, screen and bank haematopoietic stem cells (HSCs) in hundreds of repositories around the world. UCB banking has developed through a broad spectrum of overlapping banking practices, sectors and institutional forms. Superficially at least, these sectors have been widely distinguished in bioethical and policy literature between notions of the 'public' and the 'private', the commons and the market respectively. Our purpose in this paper is to reflect more critically on these distinctions and to articulate the complex practical and hybrid nature of cord blood as a 'bio-object' that straddles binary conceptions of the blood economies. The paper draws upon Roberto Esposito's reflections on biopolitics and his attempt to transcend the dualistic polarisations of immunity and community, or the private and the public. We suggest that his thoughts on immunitary hospitality resonate with many of the actual features and realpolitik of a necessarily internationalised and globally distributed UCB 'immunitary regime'.

Tissue banking in the Asia Pacific region - an overview

Tissue banking is a relative new entity in the Asia-Pacific region. Sporadic cases of tissue transplantation were reported in the early sixties whereby corneas mainly from Sri Lanka were airflown to ophthalmic surgeons in this region. Till today Sri Lanka has been playing a key role in supplying corneas and other tissues throughout the globe. Similar cases of allograft bone transplantation were reported from Myanmar during that period. However it was not until early eighties when a group of scientist medical doctors from various countries in this region met in Colombo under IAEA to discuss the possibilities of developing tissue banks in their respective countries. This development had been very slow and until today only about fourteen countries are directly involved. Due to the lack of financial support both from the authorities or non-government organizations most of the tissue banks survived by research grants from universities, the government research and development grants or grants from private bodies which are hard to come by and are usually inadequate to sustain or to maintain the banks. Most of our tissue banks started small by involving in amniotic membrane processing for use in bum patients in their initial stage of development. These are true for countries like China, Malaysia, Bangladesh, Pakistan and Indonesia where amniotic membranes are easily available and the processing cost is cheap. The availability of cobalt source for radiation of these tissues is also an important factor. Some of these banks until today still focussed on these areas whereas others had rapidly progress into production of other tissue such as bones, heart valves, allograft skin, and xenograft bones. Richer counties in the Pacific rim, where financing is not a major problem, the progress of their banks depends greatly on the demands of tissue by the clinicians and the availability of raw materials and tissue bank facilities. At the moment due to the lack of donors the raw

This paper explores the perspectives of women who have agreed that their umbilical cord blood may be collected for a public 'cord blood bank', for use in transplant medicine or research. Drawing on interview data from 27 mothers who agreed to the collection and use of their umbilical cord blood, these choices and the informed consent process are explored. It is shown that the needs of sick children requiring transplants are prominent in narrative accounts of cord blood banking, together with high expectations for future applications of stem cells. Given this dynamic, a concern arises that the complex and multiple uses of tissues and related data might be oversimplified in the consent process. In conclusion, the positive finding of a commitment to mutuality in cord blood banking among these women is underlined, and its implications for the wider debate on cord blood banking are discussed.

The importance of efficiency in the supply chain of perishable products, such as the blood products used in transfusion services, cannot be overstated. Many problems can occur, such as the outdating of products, inventory management issues, patient misidentification, and mistransfusion. The purpose of this article was to identify the benefits and barriers associated with radiofrequency identification (RFID) usage in improving the blood bank supply chain. The methodology for this study was a qualitative literature review following a systematic approach. The review was limited to sources published from 2000 to 2014 in the English language. Sixty-five sources were found, and 56 were used in this research study. According to the finding of the present study, there are numerous benefits and barriers to RFID utilization in blood bank supply chains. RFID technology offers several benefits with regard to blood bank product management, including decreased transfusion errors, reduction of product loss, and more efficient inventory management. Barriers to RFID implementation include the cost associated with system implementation and patient privacy issues. Implementation of an RFID system can be a significant investment. However, when observing the positive impact that such systems may have on transfusion safety and inventory management, the cost associated with RFID systems can easily be justified. RFID in blood bank inventory management is vital to ensuring efficient product inventory management and positive patient outcomes.

The difference was statistically significant (p < 0.001 for anti-HBc and anti-HCV. Although the predictive positive value for these surrogate markers were low for HIV infection, the results confirmed the anti-HBc and anti-HCV as useful surrogate markers for HIV infection thus reinforcing the maintenance of them in the screening for blood donors contributing to the prevention of the small number of cases in which HIV is still transmitted by transfusion.

Evaluation of the impact of banking umbilical cord blood units with high cell dose for ethnically diverse patients.

Umbilical cord blood units provide an important stem cell source for transplantation, particularly for patients of ethnic diversity who may not have suitably matched available, adult-unrelated donors. However, with the cost of cord blood unit acquisition from public banks significantly higher than that for adult-unrelated donors, attention is focused on decreasing cost yet still providing cord blood units to patients in need. Historical practices of banking units with low total nucleated cell counts, including units with approximately 90 × 10 7 total nucleated cells, indicates that most banked cord blood units have much lower total nucleated cell counts than are required for transplant. The objective of this study was to determine the impact on the ability to identify suitable cord blood units for transplantation if the minimum total nucleated cell count for banking were increased from 90 × 10 7 to 124 or 149 × 10 7 . We analyzed ethnically diverse patients (median age, 3 years) who underwent transplantation of a single cord blood unit in 2005 to 2016. A cord blood unit search was evaluated to identify units with equal or greater human leukocyte antigen matching and a greater total nucleated cell count than that of the transplanted cord blood unit (the replacement cord blood unit). If the minimum total nucleated cell count for banking increased to 124 or 149 × 10 7 , then from 75 to 80% of patients would still have at least 1 replacement cord blood unit in the current (2016) cord blood unit inventory. The best replacement cord blood units were often found among cords with the same ethnic background as the patient. The current data suggest that, if the minimum total nucleated cell count were increased for banking, then it would likely lead to an inventory of more desirable cord blood units while having minimal impact on the identification of suitable cord blood units for transplantation. © 2017 AABB.

Umbilical cord blood (UCB) stored in public inventories has become an alternative stem cell source for allogeneic stem cell transplantation. The potential use of autologous UCB from private banks is a matter of debate. In the face of the limited resources of public inventories, a discussion on "hybrid" public and private UCB banking has evolved. We aimed to explore the attitudes of the donating parents toward public and private UCB banking. A standardized, anonymous questionnaire was sent to the most recent 621 public UCB donors including items regarding satisfaction with recruitment process, the need for a second consent before release of the UCB unit for stem cell transplantation, and the donors' views on public and private UCB banking. Furthermore, we asked about their views on UCB research. Of the questionnaires, 48% were returned, and 16% were lost due to mail contact. Of our donors, 95% would donate to the public bank again. As much as 35% of them were convinced that public banking was useful. Whereas 27% had never heard about private UCB banking, 34% discussed both options. Nearly 70% of donors opted for public banking due to altruism and the high costs of private banking. Of our public UCB donors, 81% stated that they did not need a re-consent before UCB release for stem cell transplantation. In case of sample rejection, 53.5% wanted to know details about the particular research project. A total of 9% would not consent. Almost all donors would choose public banking again due to altruism and the high costs of private banking. Shortly after donation, mail contact with former UCB donors was difficult. This might be a relevant issue in any sequential hybrid banking.

Hemoterapia e febre Dengue Blood banking e Dengue fever

Full Text Available Dengue is an endemic/epidemic arboviral disease with a variable symptomatic benign course, but potentially fatal. Once in an inhabited area, the disease will exist forever, with the best achievement being to keep vectors suppressed and the disease under control. Tiger mosquitoes (aedes aegypti, aedes albopictus are active breeders and urban hunters, becoming resistant to pesticides. Global warming and population growth are propelling the disease worldwide at tropical and subtropical regions, victimizing new populations. Dengue virus is very infective, and has been transmitted by needlestick, intrapartum, through blood transfusion and mucosal contact with blood. One patient got dengue while undergoing bone marrow transplantation. We address the growing dengue epidemics in Brazil, with more than half a million official cases in 2007, to estimate the risks of transfusion transmitted dengue. Calculations however were surpassed by reality: the major Blood Center in Brazil (FHSP-USP has found dengue virus in one out of each thousand blood units. In 2007, industry sold 2,6 million disposable blood bags in Brazil. Plotting data from FHSP-USP to the whole country, 2600 blood units would have been infective. Through blood components, around 5000 patients must have received dengue virus intravenously. Beatty et al. estimated to be 1:1300 the risk for dengue transmission through blood transfusion in Puerto Rico, close to what has been demonstrated in Sao Paulo. Throughout Brazil, the average risk may be lower, but the epidemics grows towards a worst scenario. Whatever the risk is, it imposes that all blood units in Brazil (and wherever dengue is endemic must be EIA tested for dengue NS1 antigen. This marker appears early after infection, and the EIA testing platform is available at all blood banks. Also, donors must report febrile states up to two weeks after donation. Morbidity from dengue virus injected in hospitalized patients is unknown, but it may lead

Analysis of inventory strategies for blood components in a regional blood center using process simulation.

The storage of blood components is an important concern in the blood supply chain. Because these are perishable products, the definition of good inventory policies is crucial to reduce shortages and spills. To analyze and propose inventory policies in a regional blood center, a discrete event simulation model was created using simulation software (Arena 12.0, Rockwell Software). The model replicates the activities that are performed along the supply chain including donation arrivals, testing, production, inventory management, and dispatching. Twelve different scenarios were analyzed, with each one representing different inventory policies composed of a combination of an optimal inventory, a reorder point, and a level of extra donations. The best scenario demonstrates that it is possible to decrease unsatisfied demand and wastage of red blood cell units by 2.5 and 3%, respectively, when compared to current practices. This study shows that simulation is an alternative that can be used to model inventory components in blood centers. A responsible selection of inventory variables can improve the capability of the system to respond to the final patient requirements. © 2013 American Association of Blood Banks.

The total nucleated cell dosage of umbilical cord blood (UCB) is an important factor in determining successful allogeneic hematopoietic stem cell transplantation after a minimum human leukocyte antigen donor-recipient match. The northern South American population is in need of a new-generation cord blood bank that cryopreserves only units with high total nucleated cell content, thereby increasing the likelihood of use. Colombia set up a public cord blood bank in 2014; and, as a result of its research for improving high total nucleated cell content, a new strategy for UCB collection was developed. Data from 2933 collected and 759 cryopreserved cord blood units between 2014 and 2015 were analyzed. The correlation of donor and collection variables with cellularity was evaluated. Moreover, blood volume, cell content, CD34+ count, clonogenic capacity, and microbial contamination were assessed comparing the new method, which combines in utero and ex utero techniques, with the conventional strategies. Multivariate analysis confirmed a correlation between neonatal birth weight and cell content. The new collection method increased total nucleated cell content in approximately 26% and did not alter pre-cryopreservation and post-thaw cell recovery, viability, or clonogenic ability. Furthermore, it showed a remarkably low microbial contamination rate (1.2%). The strategy for UCB collection developed at the first Colombian public cord blood bank increases total nucleated cell content and does not affect unit quality. The existence of this bank is a remarkable breakthrough for Latin-American patients in need of this kind of transplantation. © 2017 The Authors Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

Cardiac surgery may cause a serious coagulopathy leading to increased risk of bleeding and transfusion demands. Blood bank products are commonly first line haemostatic intervention, but has been associated with hazardous side effect. Coagulation factor concentrates may be a more efficient, predictable, and potentially a safer treatment, although prospective clinical trials are needed to further explore these hypotheses. This study investigated the haemostatic potential of ex vivo supplementation of coagulation factor concentrates versus blood bank products on blood samples drawn from patients undergoing cardiac surgery. 30 adults were prospectively enrolled (mean age=63.9, females=27%). Ex vivo haemostatic interventions (monotherapy or combinations) were performed in whole blood taken immediately after surgery and two hours postoperatively. Fresh-frozen plasma, platelets, cryoprecipitate, fibrinogen concentrate, prothrombin complex concentrate (PCC), and recombinant FVIIa (rFVIIa) were investigated. The haemostatic effect was evaluated using whole blood thromboelastometry parameters, as well as by thrombin generation. Immediately after surgery the compromised maximum clot firmness was corrected by monotherapy with fibrinogen or platelets or combination therapy with fibrinogen. At two hours postoperatively the coagulation profile was further deranged as illustrated by a prolonged clotting time, a reduced maximum velocity and further diminished maximum clot firmness. The thrombin lagtime was progressively prolonged and both peak thrombin and endogenous thrombin potential were compromised. No monotherapy effectively corrected all haemostatic abnormalities. The most effective combinations were: fibrinogen+rFVIIa or fibrinogen+PCC. Blood bank products were not as effective in the correction of the coagulopathy. Coagulation factor concentrates appear to provide a more optimal haemostasis profile following cardiac surgery compared to blood bank products. Copyright © 2017

2016-10-01

The Formosa Fun Coast explosion, occurring in a recreational water park located in the Northern Taiwan on 27 June 2015, made 499 people burn-injured. For those who had severe burn trauma, surgical intervention and fluid resuscitation were necessary, and potential blood transfusion therapy could be initiated, especially during and after broad escharotomy. Here, we reviewed the literature regarding transfusion medicine and skin grafting as well as described the practicing experience of combined tissue and blood bank in the burn disaster in Taiwan. It was reported that patients who were severely burn-injured could receive multiple blood transfusions during hospitalization. Since the use of skin graft became a mainstay alternative for wound coverage after the early debridement of burn wounds at the beginning of the 20th century, the development of tissue banking program was initiated. In Taiwan, the tissue banking program was started in 2006. And the first combined tissue and blood bank was established in Far Eastern Memorial Hospital in 2010, equipped with the non-sterile, clean and sterile zones distinctly segregated with a unidirectional movement in the sterile area. The sterile zone was a class 10000 clean room equipped with high efficiency particulate air filter (HEPAF) and positive air pressure ventilation. The combined tissue and blood bank has been able to provide the assigned blood products and tissue graft timely and accurately, with the concepts of centralized management. In the future, the training of tissue and blood bank technicians would be continued and fortified, particularly on the regulation and quality control for further bio- and hemovigilance.

A formal sales and operations planning (S&OP) process is a decision making and communication process that balances supply and demand while integrating all business operational components with customer-focused business plans that links high level strategic plans to day-to-day operations. Furthermore, S&OP can assist in managing change across the organization as it provides the opportunity to be proactive in the face of problems and opportunities while establishing a plan for everyone to follow. Some of the key outcomes from a robust S&OP process in blood banking would include: higher customer satisfaction (donors and health care providers), balanced inventory across product lines and customers, more stable production rates and higher productivity, more cooperation across the entire operation, and timely updates to the business plan resulting in better forecasting and fewer surprises that negatively impact the bottom line. © 2010 American Association of Blood Banks.

Unrelated Bone marrow transplant was initiated thirty years ago. Though there are over millions of donors registered with the bone marrow registries worldwide, Asian patients rarely find a match with all these donors. Tzu Chi Marrow Donor Registry was established to meet this need. It has become the largest Asian marrow donor registry in the world. With the introduction of high technology to test the HLA of the donors and recipients, the success rate of bone marrow transplant is greatly improved among Asian countries. 50% of blood disease Asian patients who cannot find a bone marrow matched donor will be complemented by the establishment of cord blood banks in Taiwan.

Full Text Available ABO and Rhesus (Rh blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly in compatibility test in blood transfusion practice. Data on frequency distribution of ABO and Rh-D in Niger-Delta region of Nigeria are not available; hence we made an attempt to retrospectively analyze the records on the blood donors, transfusion recipients and patients attending antenatal care or some other medical interventions. Over a twenty-year period between 1986 and 2005, a total of 160,431 blood samples were grouped for ABO and Rh-D at the blood bank of the University of Benin Teaching Hospital, Benin City, Nigeria. Blood group distribution among these samples showed phenotypes A, B, AB and O as 23.72%, 20.09%, 2.97% and 53.22%, respectively. The Rh-D negative phenotype was found among 6.01% of the samples tested.

The problem that arises according to this spin-off is the existence of sharia unit that owned by the regional development banks, which is almost the banks has a small size. This paper is going to evaluate the spin-off criteria are regional development banks, besides that this article is going to analyze the spin-off strategy that can use by sharia unit that owned by the regional development bank. The techniques that employed in this paper are ARIMA, simulation, and descriptive-qualitative. The result shows that there is no sharia unit can achieve the 50% share asset of its parents. There are also several strategies that can be used by the sharia unit. The main thing that should emphasize is the Islamic bank's spin-off is only one of the policies that can be taken to develop the Islamic banking industryDOI: 10.15408/aiq.v9i1.4308 

La experiencia de Perú con un programa nacional de bancos de sangre Peru's experience with a national blood banking program

Full Text Available This paper describes Peru's experiences with its National Blood Banking Program. Until the mid-1990s, the country faced a host of problems, including the lack of a legal framework to regulate blood banks, a high maternal mortality rate due to a shortage of blood, virtually no voluntary donations, a high risk of infection from transfusions, the use of only whole blood for transfusion, serious disorganization in the blood banks, deficiencies in blood bank supervision and control, no training programs, indifference on the part of health officials, frequent selling of blood, and limited community awareness. Subsequently, a strategic plan was prepared that made it possible to solve many of those problems. Legal instruments were prepared; the rate of voluntary donations rose from 0% to 19.5%; the safety of the blood was improved through compulsory screening of all donated blood units for seven markers of infectious diseases, as well as by placing a national seal of quality on all screened units. The availability of blood doubled, thus meeting 70% of the need; sales of blood decreased; and the use of blood components was improved, with 80% of the blood being fractionated. In addition, supervisory control of 100% of the blood banks in the country was achieved, a national registry was established, the cost-benefit relationship for blood units was improved through centralized screening, internal and external quality control was made mandatory, and prodonation campaigns led to commitments from civil society. While important, all these achievements represent just a first step. This is especially true given that developing the National Blood Banking Program required the participation of outside organizations, such as the Pan American Health Organization, whose support, together with the experience provided by other countries, was key. The Program is facing a number of new challenges, and the progress that has been achieved could be threatened if current

Ecoevolutionary processes affecting hosts, vectors and pathogens are important drivers of zoonotic disease emergence. In this study, we focused on nephropathia epidemica (NE), which is caused by Puumala hantavirus (PUUV) whose natural reservoir is the bank vole, Myodes glareolus. We questioned the possibility of NE emergence in a French region that is considered to be NE-free but that is adjacent to a NE-endemic region. We first confirmed the epidemiology of these two regions and we demonstrated the absence of spatial barriers that could have limited dispersal, and consequently, the spread of PUUV into the NE-free region. We next tested whether regional immunoheterogeneity could impact PUUV chances to circulate and persist in the NE-free region. We showed that bank voles from the NE-free region were sensitive to experimental PUUV infection. We observed high levels of immunoheterogeneity between individuals and also between regions. Antiviral gene expression (Tnf and Mx2) reached higher levels in bank voles from the NE-free region. During experimental infections, anti-PUUV antibody production was higher in bank voles from the NE-endemic region. These results indicated a lower susceptibility to PUUV for bank voles from this NE-free region, which might limit PUUV persistence and therefore, the risk of NE.

Quality Control in Screening for Infectious Diseases at Blood Banks. Rationale and Methodology.

Quality control procedures are indispensable to ensure the reliability of the results provided by laboratories responsible for serological screening in blood banks. International recommendations on systems of quality management classify as a top component the inclusion of two types of control: (a) internal quality control (IQC) and (b) external quality control (EQC). In EQC it is essential to have, at least, a monthly frequency of laboratory assessment. On the other hand, IQC involves the daily use of low-reactivity control sera, which should be systematically added in all run, carried out in the laboratory for each parameter. Through the IQC analysis some variations in the criteria of run acceptance and rejection may be revealed, but it is of paramount importance to ensure the previous definition of these criteria and even more importantly, the adherence to them; and that corresponds to the validation of analytical runs of each test. Since 2010 this has been, for instance, the experience of the PNCQ*, developing external quality control programmes on serology for blood banks. These programmes use samples of lyophilized sera well-characterized for the reactivity related to the parameters used for the serological screening of blood donors. The programmes have used blind panels of six samples for monthly assessments. In the last 50 assessments, which involved 68 blood banks in Brazil, a significant number of instances of non-compliance were observed in all monthly assessments. These results provide strong support to the recommendation of systematic monthly assessments. (*) National Quality Control Programme (PNCQ).

Full Text Available The management of the stocks of products derived from the blood processing collected in blood banks is a problem for health services in Brazil and the world. Quantify the stocks of these products in order to equalize the demand and supply is not a simple task. It's necessary ensure that the product is available when needed and in due time. However, there is no how overestimate these stocks given that the product is perishable and it is not easy the availability of raw material (blood for processing. There are few studies in Brazil, however, that discuss this issue. This study will focus on one Brazilian Hemocentro, which has faced the challenge of measure the demand for haemotherapic's products and establish parameters to control their stocks. Thus, it was sought to adapt a recent study realized out of the country, about sizing of stocks of a inventory for blood banks, combined with a forecast model of demand for blood derivatives subclassified by blood type. This control aims to increase the availability of the transfusion service, as it intends to reduce shortages and wastage of the blood collected.

Full Text Available Context: A total of 30 million blood components are transfused each year in India. Blood safety thus becomes a top priority, especially with a population of around 1.23 billion and a high prevalence rate of human immunodeficiency virus (HIV, hepatitis B virus (HBV and hepatitis C virus (HCV in general population. Nucleic acid amplification testing (NAT in blood donor screening has been implemented in many developed countries to reduce the risk of transfusion-transmitted viral infections (TTIs. NAT takes care of the dynamics of window period of viruses and offers the safest blood pack for donation. Aims: The aim of this study is to show the value of NAT in blood screening. Settings and Design: Dhanavantari Blood Bank, Rajahmundry, Andhra Pradesh, India. Subjects and Methods: Over a period of 1 year from January 2012 to December 2012, a total number of 15,000 blood donor samples were subjected to tests for HIV, HBV, and HCV by enzyme-linked immunosorbent assay (ELISA method and 8000 ELISA nonreactive samples were subjected for NAT using multiplex polymerase chain reaction technology. Results: Of the 15,000 donors tested, 525 were seroreactive. In 8000 ELISA negative blood samples subjected to NAT, 4 donor samples were reactive for HBV. The NAT yield was 1 in 2000. Conclusions: NAT could detect HIV, HBV, and HCV cases in blood donor samples those were undetected by serological tests. NAT could interdict 2500 infectious donations among our approximate 5 million annual blood donations.

Current blood banking procedures may not fully preserve red blood cell (RBC) function during storage, contributing to the decrease of RBC oxygen release ability. This study was undertaken to evaluate the impact of routine cold storage on RBC oxygen release ability. RBC units were collected from healthy donors and each unit was split into two parts (whole blood and suspended RBC) to exclude possible donor variability. Oxygen dissociation measurements were performed on blood units stored at 4 °C during a 5-week period. 2,3-diphosphoglycerate levels and fluorescent micrographs of erythrocyte band 3 were also analysed. P50 and oxygen release capacity decreased rapidly during the first 3 weeks, and then did not change significantly. In contrast, the kinetic properties (PO2-t curve and T*50) of oxygen release changed slowly during the first 3 weeks of storage, but then decreased significantly in the last 2 weeks. 2,3-diphosphoglycerate decreased quickly during the first 3 weeks of storage to almost undetectable levels. Band 3 aggregated significantly during the last 2 weeks of storage. RBC oxygen release ability appears to be sensitive to routine cold storage. The thermodynamic characteristics of RBC oxygen release ability changed mainly in the first 3 weeks of storage, due to the decrease of 2,3-diphosphoglycerate, whereas the kinetic characteristics of RBC oxygen release ability decreased significantly at the end of storage, probably affected by alterations of band 3.

Pre-transfusion testing includes proper requisitions, compatibility testing and pre-release checks. Proper labelling of samples and blood units and accurate patient details check helps to minimize the risk of errors in transfusion. This study was aimed to identify requisition errors before compatibility testing. The study was conducted in the blood bank of a tertiary care hospital in north India over a period of 3 months. The requisitions were screened at the reception counter and inside the pre-transfusion testing laboratory for errors. This included checking the Central Registration number (C.R. No.) and name of patient on the requisition form and the sample label; appropriateness of sample container and sample label; incomplete requisitions; blood group discrepancy. Out of the 17,148 blood requisitions, 474 (2.76 %) requisition errors were detected before the compatibility testing. There were 192 (1.11 %) requisitions where the C.R. No. on the form and the sample were not tallying and in 70 (0.40 %) requisitions patient's name on the requisition form and the sample were different. Highest number of requisitions errors were observed in those received from the Emergency and Trauma services (27.38 %) followed by Medical wards (15.82 %) and the lowest number (3.16 %) of requisition errors were observed from Hematology and Oncology wards. C.R. No. error was the most common error observed in our study. Thus a careful check of the blood requisitions at the blood bank reception counter helps in identifying the potential transfusion errors.

Backround: ABO and Rhesus (Rh) blood group antigens are hereditary characters and are useful in population genetic studies, in resolving medico-legal issues and more importantly for the immunologic safety of blood during transfusion. This study is aimed to determine the distribution pattern of the ABO and Rh blood groups among blood donors in Kumaon region of Uttarakhand and compare it with other data from similar studies within the India and all over the world. It is a retrospective study carried out at blood bank of Shushila Tewari Hospital of Government Medical College, Haldwani from January 2012 to December 2013. The study was conducted on 12,701 blood donors. ABO and Rh typing was done using slide agglutination method with antisera ABO and Rh (Tulip diagnostics ltd). Doubtful cases were confirmed by tube agglutination method and reverse grouping using known pooled A and B cells. The age group and sex of donors, frequency of ABO and Rh blood groups were reported in simple percentages. The predominant donors belonged to age group between 18-35years (84.28%). Male donors were more than female donors, ratio being 352:1. Replacement donors (99.71%) were much more than voluntary donors (0.91%). The most common blood group was B (32.07%) and least common being AB (10.53%). Blood group 'O' and 'A' had same frequency. The prevalence of Rhesus positive and negative distribution in the studied population was 94.49% and 5.51% respectively. Blood group frequency with respect to ABO and Rhesus positive was found to be shown by formula B> O>A >AB. The frequency for ABO and Rhesus negative was given by the formula B>A>O>AB. Knowledge of frequencies of the different blood groups is very important for blood banks and transfusion service policies that could contribute significantly to the National Health System.

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

1998-08-01

Promising clinical results suggest that umbilical cord blood (UCB) collected after delivery of a child may have many advantages over bone marrow for transplantation. As there are an increasing number of options regarding the collection of UCB, including private and public banking, more pregnant women are likely to be asked to make decisions about UCB collection. We conducted three focus groups with pregnant women to learn about their perspectives on this emerging technology. All the women in these focus groups indicated that they would choose to have UCB collected. Reasons leading to this choice were that the UCB would otherwise be discarded and altruism. Participants indicated that possible reasons to decide not to have UCB collected include concerns about the safety of the mother and neonate, beliefs about the placenta, threats against confidentiality, rejection of UCB, and the influence of fathers. While feeling confident in making an anticipatory decision about UCB collection, women expressed a clear desire to learn much more about the collection, storage (including distinctions between public and private banking), and use of UCB. In addition, they believed that recruitment for UCB collection should occur after sufficient education about UCB and certainly not after delivery and collection. These data will be useful in guiding efforts to help women make decisions about having UCB collected and in developing an appropriate recruitment and informed consent process for donating UCB to a public bank.

The concept of Umbilical Cord blood (UCB) stem cells is emerging as a non-invasive, efficacious alternative source of hematopoietic stem cells to treat a variety of blood and bone marrow diseases, blood cancers, metabolic disorders and immune deficiencies. Aim of the present study was to determine the level of awareness about banking UCB among pregnant women in India. We also assessed patient perception for banking of UCB and explored the patient expectations of banking UCB in future. This is the first study to assess current attitudes, in a sample population of potential donors from one of the largest potential UCB repository (India). Obtaining this information may help optimize recruitment efforts and improve patient education. Present explorative questionnaire based survey included 254 pregnant women in the final analysis. We established only 26.5% pregnant women in our study population knew what exactly is meant by UCB. A large proportion (55.1%) was undecided on whether they want to bank UCB or not. Women were more aware of the more advertised private cord blood banking compared to public banking. More than half of the pregnant women expected their obstetrician to inform them regarding UCB. One-third of the women in our population had undue expectations from banking of the UCB. Obstetricians should play a more active role in explaining the patients regarding pros and cons of UCB banking.

During the past four decades, many tissue banks have been established across the world with the aim of supplying sterilized tissues for clinical use and research purposes. Between 1972 and 2005, the International Atomic Energy Agency supported the establishment of more than sixty of these tissue banks in Latin America and the Caribbean, Asia and the Pacific, Africa and Eastern Europe; promoted the use of the ionizing radiation technique for the sterilization of the processed tissues; and encouraged cooperation between the established tissue banks during the implementation of its program on radiation and tissue banking at national, regional and international levels. Taking into account that several of the established tissue banks have gained a rich experience in the procurement, processing, sterilization, storage, and medical use of sterilized tissues, it is time now to strengthen further international and regional cooperation among interested tissue banks located in different countries. The purpose of this cooperation is to share the experience gained by these banks in the procurement, processing, sterilization, storage, and used of different types of tissues in certain medical treatments and research activities. This could be done through the establishment of a network of tissue banks and a limited number of regional tissue processing centers in different regions of the world.

The introduction of a stand-alone Bone Bank in our Regional Orthopaedic Hospital has improved the availability of femoral head allograft. Benninger et al. (Bone Joint J 96-B:1307-1311, 2014), demonstrated their institutions bank to be cost effective despite a 30 % discard rate for harvested allograft. We sought to audit our own discard rates and subsequent cost-effectiveness of our bone bank. Donor recruitment. Before approaching a potential donor, our establishment's nurse specialists review their clinical notes and biochemical laboratory results, available on a regional Electronic Care Records. They view femoral head architecture on radiographs against set criteria, Patient Archive and Communication system (SECTRA, Sweden). In total 1383 femoral heads were harvested, 247 were discarded giving an overall rate of 17.9 %. The most common reasons for discard of harvested graft was a positive microbiology/bacteriology result, n = 96 (38.9 %). After a rise in discard rates in 2007, we have steadily reduced our discard rates since 2006/2007 (28.2 %), 2008/2009 (17 %), 2010/2011 (14.8 %), and finally to 10.3 % in 2012/2013. In the current financial year, our cost to harvest, test, store and release a femoral head is £ 610. With a structured donor recruitment process and unique pre-operative radiographic analysis we have successfully reduced our discard rates bi-annually making our bone bank increasingly cost-effective.

The main objective of the present study was to evaluate the temperature chain of red blood cells (RBC) returned unused blood bags using blood temperature indicator and ascertain the factors like transportation time, type, size of coolant box and number of bags per box. A total of 250 blood bags with the indicator were observed for the temperature changes with other factors like transportation time, type and size of coolant box and number of bags per box. The recordings were performed at several checkpoints located between the blood bank and the wards. Out of the 250 bags, 74 (29.6%) showed colour changes in which 64 (86.3%) were returned unused (RU) blood bags. The transportation time for these 74 bags was 818.3 ± 941.643 min, significantly higher than bags without colour changes, (p=0.02). Interestingly, 71.4% of the colour changes occurred within the ward. The 7 litre coolant box with an average of 1-5 blood bags per box had a statistically significant higher percentage of colour change with 59.2% compared to the 5 litre coolant box (p=0.05). This study showed that the temperature chain of blood bags was often not well maintained. These results could be mainly due to the non-adherence to the standard operating procedure (SOP) of blood transfusion and the usage of non-standardized coolant boxes.

To establish the confirmatory diagnosis of Trypanosoma cruzi infection, at least two immunoserological tests (ELISA, Indirect hamaglutination, IH, Complement Fixation Test, CFT) were carried out in 254 donors, from public and private blood banks of Venezuela, during 48 months between 1997-1998 and 2003-2004, referred to the Immunology Section of the Tropical Medicine Institute in Caracas. Antibodies anti-T. cruzi were detected in 129/254 (50,79%) by ELISA-IgG or IH and CFT. The "artificial xenodiagnosis" was positive in 10/118 persons with positive confirmed serology. Of 129 donors found positive by the serological tests, 68 were living in the capital region and 61 in the interior of the country. Likewise 113 were born in the interior of the country, 8 in Caracas and 8 in Colombia. Of them, 12 individuals serologically confirmed declared to have donated blood in a minimum of 4 occasions before diagnosis. The present study emphasizes the importance of detection of antibodies against T. cruzi in the integral evaluation of blood donors, since many of them with antibodies anti-T. cruzi, have donated blood several times previous to diagnosis.

The quest for quality blood banking program in the new millennium the American way.

Kim, Dae Un

2002-08-01

For an industry to succeed and satisfy its customers, "QUALITY" must be a primary goal. Quality has been central to blood banking from its inception, with the evolution of a Quality Program since the opening of the first blood bank in U.S. at the Cook County Hospital in 1937. Over the ensuing decades, continuous scientific progress in blood preservation, filters, viral and blood group testing, crossmatching, automation, and computerization including bar coding, etc. has contributed to the quality and safety of the blood products and transfusion service. However, with the advent of the AIDS era, an increasingly sensitized and informed public is continuously demanding that the highest level of quality be achieved and maintained in all processes involved in providing all blood products. The Food and Drug Administration (FDA) introduced the concept of a "zero risk blood supply" as the industry goal. Furthermore, the cost containment and resource-constrained environment have changed the complexity of the quality practice. Both regulatory agencies such as the FDA, the Health Care Financing Administration [HCFA, which was recently renamed as the Centers for Medicare and Medicaid Services (CMS) in July, 2001], and the State Department of Health, and accrediting agencies, such as the American Association of Blood Banks (AABB), the College of American Pathologists (CAP), and the Joint Commission on Accreditation of Healthcare Organizations (JCAHO), require blood banks and transfusion services to establish and follow a Quality Control and Quality Assurance Program for their licensing, certification and accreditation. Every laboratory has to comply with the Clinical Laboratory Improvement Amendments of 1988 (CLIA '88) quality requirements being implemented by the CMS. The FDA guidelines assist facilities in compliance with Current Good Manufacturing Practices (cGMP). The AABB's Quality System Essentials (QSE) are based on these specifications and provide additional guidance in

Zika virus has emerged as a potential threat to the Canadian blood supply system. Stem cell donors within Canadian Blood Services' Cord Blood Bank (CBB) and OneMatch Stem Cell and Marrow Network (OM) now undergo screening measures designed to reduce the risk of Zika virus transmission. The impact these screening measures have on cord blood and unrelated adult stem cell donations is currently unknown. Among 146 donor workups initiated by OM between July 2016 and May 2017, 102 were completed and 44 workups were canceled. There were 17 potential donors (11.6%) with a risk of Zika virus exposure identified by the donor questionnaire (13 completed, 4 canceled workups). None of the workups involved a donor diagnosed with confirmed Zika virus within the past 6 months. Only 1 of the 44 canceled workups (and only 1 of 4 cases with a risk of Zika transmission) was canceled because of the risk of Zika transmission, and a backup donor was selected. Canadian Blood Services' CBB identified 25 of 875 cord blood units (2.9%) from women who donated their infants' cord blood and underwent screening that otherwise met the initial cell number thresholds for banking and had at least 1 risk factor for exposure to Zika virus. No women were diagnosed with Zika virus at any point of their pregnancy. All 25 units were discarded. Unrelated donors at OM have a higher incidence of a risk of exposure to Zika virus compared with cord blood donors. Only rarely did transplant centers cancel donor workups due to potential Zika virus exposure. The impact of screening for Zika virus exposure risk on cord blood banking was minor. Continued vigilance and surveillance is recommended. Copyright © 2017 The American Society for Blood and Marrow Transplantation. Published by Elsevier Inc. All rights reserved.

2011-12-01

This study evaluated the acceptance of blood donors concerning the donation stages (attendance, medical and nursing selection and collection) at the Recife public blood bank with emphasis on the attendance. A sample of 527 donors was obtained: each 19th person sequentially was invited to answer a questionnaire. Chi-square (x2) was used in the analysis. Of those interviewed, 81.4% were men, 81% were repeat donors, 50.3% were dissatisfied regarding the time spent in donation and 36.4% had difficulties in reaching the service. The firm acceptance given to the attendance was due mainly to the communication and the quality of treatment. Of statistical significance were women donors of higher educational level who asked for more information and men who had a more positive perception towards the selection process. The best evaluation was attributed to the collection sector. However, mention was made of impersonal treatment, persistence of doubts and the cursory nature of the medical interview. Attention focused on the donor requires that ongoing education should concentrate on the humanitarian formation of the professionals involved.

Full Text Available Legal issues play a vital role in providing a framework for the Indian blood transfusion service (BTS, while ethical issues pave the way for quality. Despite licensing of all blood banks, failure to revamp the Drugs and Cosmetic Act (D and C Act is impeding quality. Newer techniques like chemiluminescence or nucleic acid testing (NAT find no mention in the D and C Act. Specialised products like pooled platelet concentrates or modified whole blood, therapeutic procedures like erythropheresis, plasma exchange, stem cell collection and processing technologies like leukoreduction and irradiation are not a part of the D and C Act. A highly fragmented BTS comprising of over 2500 blood banks, coupled with a slow and tedious process of dual licensing (state and centre is a hindrance to smooth functioning of blood banks. Small size of blood banks compromises blood safety. New blood banks are opened in India by hospitals to meet requirements of insurance providers or by medical colleges as this a Medical Council of India (MCI requirement. Hospital based blood banks opt for replacement donation as they are barred by law from holding camps. Demand for fresh blood, lack of components, and lack of guidelines for safe transfusion leads to continued abuse of blood. Differential pricing of blood components is difficult to explain scientifically or ethically. Accreditation of blood banks along with establishment of regional testing centres could pave the way to blood safety. National Aids Control Organisation (NACO and National Blood Transfusion Council (NBTC deserve a more proactive role in the licensing process. The Food and Drug Administration (FDA needs to clarify that procedures or tests meant for enhancement of blood safety are not illegal.

Over the last 2 decades, cord blood (CB) has become an important source of blood stem cells. Clinical experience has shown that CB is a viable source for blood stem cells in the field of unrelated hematopoietic blood stem cell transplantation. Studies of CB units (CBUs) stored and ordered from the US (National Marrow Donor Program (NMDP) and Swiss (Swiss Blood Stem Cells (SBSQ)) CB registries were conducted to assess whether these CBUs met the needs of transplantation patients, as evidenced by units being selected for transplantation. These data were compared to international banking and selection data (Bone Marrow Donors Worldwide (BMDW), World Marrow Donor Association (WMDA)). Further analysis was conducted on whether current CB banking practices were economically viable given the units being selected from the registries for transplant. It should be mentioned that our analysis focused on usage, deliberately omitting any information about clinical outcomes of CB transplantation. A disproportionate number of units with high total nucleated cell (TNC) counts are selected, compared to the distribution of units by TNC available. Therefore, the decision to use a low threshold for banking purposes cannot be supported by economic analysis and may limit the economic viability of future public CB banking. We suggest significantly raising the TNC level used to determine a bankable unit. A level of 125 × 10(7) TNCs, maybe even 150 × 10(7) TNCs, might be a viable banking threshold. This would improve the return on inventory investments while meeting transplantation needs based on current selection criteria.

The use of freely diffusable inert radioactive gas as a washout indicator to measure regional cerebral blood flow has become a standardized kinetic procedure in many laboratories. Recent investigations with this technique have led us to conclude that we can reliably distinguish regional flow with perfusion against regional flow without perfusion from the early portion of the curve. Based on a detailed study of the early curve kinetics in patients with and without cerebral vascular disease we have defined the sampling duration necessary for application of the Anger gamma camera imaging process to regional changes in cerebral radioactivity. Using a standard camera and a small computer, a procedure has been developed and based upon entire field to determine the time of maximum height followed by analysis of the data in a matrix. This will permit a contour plot presentation of calculated regional cerebral blood flow in millilitres per 100 grams perfused brain per minute. In addition, we propose to augment this data by the display of regional non-perfusion blood flow versus regional cerebral flow with perfusion. Preliminary investigation on sampling duration, and Compton scattering were prerequisite to clinical scintigraphy of regional cerebral blood flow. In addition, the method of interface for the conventional Anger gamma camera to digital computers used in this procedure are discussed. Applications to further assess regional cerebral dynamics by scintigraphy are presented. (author)

Trust, nostalgia and narrative accounts of blood banking in England in the 21st century.

Science.gov (United States)

Wynne Busby, Helen

2010-07-01

Historically, cultural accounts and descriptions of blood banking in Britain have been associated with notions of altruism, national solidarity and imagined community. While these ideals have continued to be influential, the business of procuring and supplying blood has become increasingly complex. Drawing on interview data with donors in one blood centre in England, this article reports that these donors tend not to acknowledge the complex dynamics of production and exchange in modern blood systems. This, it is argued, is congruent with nostalgic narratives in both popular and official accounts of blood services, which tend to bracket these important changes. A shift to a more open institutional narrative about modern blood services is advocated, as blood services face current and future challenges.

Full Text Available Background: Sultanate of Oman is geographically situated in south-west of Asia, having common borders on western side by the land with United Arab Emirates, Saudi Arabia and Yemen and with the Arabian Sea and the Gulf of Oman in the east and the north respectively. The country enjoys one of the best health care facilities including blood transfusion services in the region. Study design: Information was collected through informal personal interviews, digging out the past records, and the report presentations at various forums. Results: A modest start by providing blood units through import, the country is now self-reliant on procuring blood units from voluntary non-remunerate blood donors within the sultanate. A steady growth of blood banks is witnessed in every aspect of blood banking including blood collection, blood processing and supply. Various modalities are adapted in promoting voluntary blood donation programme. Conclusion: Sultanate of Oman has created one of the best blood transfusion services in the region in providing safe blood for transfusion through voluntary donation, a use of blood components and irradiating blood products.

Full Text Available Banking sector is an important development factor of the total financial and economic system. Number of banks and dispersion of their individual shares defines competitive structure of banking sector, manifested by its concentration. Market concentration may be presented as a function of a number of enterprises competing in a market and their individual comparative market shares. Concentration analysis is significant with regard to the fact that the level of concentration demonstrates relations among competitors in a market, as well as influence each competitor has on consumers, branch and economy as a whole. Starting from 2008 crisis, domino effect of which hit banking sector and has had a huge impact on it, authors of this paper aimed at establishing a level of market concentration of the banking sector in Serbia and countries in the region in 2015 by application of a large number of market concentration indicators.

Bank storage buffers rivers from saline regional groundwater: an example from the Avon River Australia

Gilfedder, Benjamin; Hofmann, Harald; Cartwrighta, Ian

Groundwater-surface water interactions are often conceptually and numerically modeled as a two component system: a groundwater system connected to a stream, river or lake. However, transient storage zones such as hyporheic exchange, bank storage, parafluvial flow and flood plain storage complicate the two component model by delaying the release of flood water from the catchment. Bank storage occurs when high river levels associated with flood water reverses the hydraulic gradient between surface water and groundwater. River water flows into the riparian zone, where it is stored until the flood water recede. The water held in the banks then drains back into the river over time scales ranging from days to months as the hydraulic gradient returns to pre-flood levels. If the frequency and amplitude of flood events is high enough, water held in bank storage can potentially perpetually remain between the regional groundwater system and the river. In this work we focus on the role of bank storage in buffering river salinity levels against saline regional groundwater on lowland sections of the Avon River, Victoria, Australia. We hypothesize that the frequency and magnitude of floods will strongly influence the salinity of the stream water as banks fill and drain. A bore transect (5 bores) was installed perpendicular to the river and were instrumented with head and electrical conductivity loggers measuring for two years. We also installed a continuous 222Rn system in one bore. This data was augmented with long-term monthly EC from the river. During high rainfall events very fresh flood waters from the headwaters infiltrated into the gravel river banks leading to a dilution in EC and 222Rn in the bores. Following the events the fresh water drained back into the river as head gradients reversed. However the bank water salinities remained ~10x lower than regional groundwater levels during most of the time series, and only slightly above river water. During 2012 SE Australia

An Analysis of and Recommendations for the Peruvian Blood Collection and Transfusion System.

Peru experienced a crisis in its blood collection and supply system in the mid-2000s, as contaminated blood led to several transfusion-transmitted infections (TTI), occurring in the backdrop of extremely low voluntary donation rates and a national blood supply shortage. Thus, the Peruvian Ministry of Health (MINSA) implemented a national investigation on the safety and quality of the Peruvian blood collection/transfusion network. Every Peruvian blood bank was evaluated by MINSA from 2007-2008. These evaluations consisted of an update of the national registry of blood banks and visits to each blood bank from MINSA oversight teams. Information was collected on the condition of the blood bank personnel, equipment, supplies, and practices. Further, previously-collected blood at each blood bank was randomly selected and screened for TTI-causing pathogens. Uncovered in this investigation was a fragmented, under-equipped, and poorly-staffed blood collection and transfusion network, consisting of 241 independent blood banks and resulting in suboptimal allocation of resources. Further, blood with evidence of TTI-causing pathogens (including Hepatitis B, Hepatitis C, and syphilis) and set for transfusion was discovered at three separate blood banks as part of the random screening process. Using the successful reorganizations of national blood supply systems in other Latin American countries as examples, Peru would be well-served to form large, high-volume, regional blood collection and transfusion centers, responsible for blood collection and screening for the entire country. The small, separate blood banks would then be transformed into a network of blood transfusion centers, not responsible for blood collection. This reorganization would allow Peru to better utilize its resources, standardize the blood collection and transfusion process, and increase voluntary donation, resulting in a safer, more abundant national blood product.

Umbilical cord blood (UCB) represents an alternative source of stem cells for transplantation for the treatment of hematologic malignancies and genetic disorders. There is scarce information detailing cord blood bank (CBB) collection and transplantation activities from developing countries. We documented our experience at a public university hospital in northeast Mexico. We carried out a retrospective and descriptive analysis of our CBB activity during an 8-year period from May 2002 to September 2010. Collection, processing, and cryopreservation of CB were carried out following standard operating procedures. The minimum volume and total nucleated cell (TNC) content for cryopreservation were 80 mL and 8.0 × 10(8) , respectively. A total of 1256 UCB units were collected; 428 (34%) were banked and 828 (66%) were discarded. The main reason for exclusion was biologic: low volume and/or low number of TNC accounted for 84% of the total discarded units. Cryopreserved cord blood units (CBUs) had a median volume of 113.8 mL (range, 80-213.2 mL) and 13.0 × 10(8) (range, 8 × 10(8) -36.6 × 10(8) ) TNCs. Cell viability was 99.3% (88-100%). The median CD34+ cell content was 4.0 × 10(6) (0.46 × 10(6) -19.38 × 10(6) ). Sixteen units have been released for transplantation, leading to a utilization rate of 3.7%. CBB demands considerable human and financial resources; it is then essential for centers at developing countries to share their experience, results, and databases to increase the probability of finding matching units for their patients. Efforts to create and maintain CBBs allow to offer this therapeutic option at an affordable cost. © 2012 American Association of Blood Banks.

Regulation of transfusion or blood banking facilities has followed, rather than preceded the regulation of the pharmaceutical industry and today we find, in Europe and the United States, the basic regulations developed for the pharmaceutical industry being extended to blood transfusion centres (BTC)*. In this article we explore the role of voluntary accreditation or registration to quality systems standards such as ISO 9000 and discuss how these can be used to advantage and how these standards can provide a substantial base for meeting legislative requirements. In the UK there is also a voluntary accreditation procedure available for all clinical laboratories, known as Clinical Pathology Accreditation (CPA). Comparisons between ISO 9000, CPA and other standards are made. We also discuss how voluntary registration, particularly to ISO 9000 can provide an excellent basis for moving into more extensive and progressive Total Quality Management (TQM) programmes which in turn bring a variety of benefits, not least of which is increased staff involvement in your organisation. Experience of the route to quality through voluntary accreditation suggests that external assessment delivers new insights into the organisation that cannot easily be supplanted by internal audit. In Europe legislation relating to pharmaceuticals has steadily increased in scope and in detailed requirements from those set out in the 1965 Directive 65/65/EEC. The legislative framework has steadily increased, bringing plasma and plasma products as well as others such as radiopharmaceuticals, into the product licensing requirements. The progression of legislation seems unlikely to cease and it is debatable how long the Medicines Control Agency (MCA) and its Inspectorate will accept that BTCs can operate at a level which is different from that of the majority of pharmaceutical manufacturers. The change in emphasis in legislation particularly in Europe means that harm that is caused to a patient by a blood

Meissner-Roloff, Madelein; Pepper, Michael S

2013-12-01

South Africa (SA) faces a large unmet need for bone marrow (BM) transplantation, which could be alleviated in part by establishing a public umbilical cord blood stem cell bank (UCB SCB). Umbilical cord blood is an increasingly utilised source of hematopoietic stem cells for BM transplantation in addition to BM or mobilized peripheral blood stem cells. Establishing a public UCB SCB would therefore be a positive step towards improving the quality of health care in SA by providing for an important unmet need. This study takes the form of an enquiry into the acceptability of establishing a public bank through an interview with and questionnaire completed by mothers-to-be in the antenatal clinic of a large public hospital in SA. Initial results are positive, with 85 % of the participants in favour of establishing a public UCB SCB in SA. This initial probe will serve as a model for a more comprehensive national enquiry into public support and acceptability in different clinics, hospitals and provinces in SA.

This study focuses on the detection and identification of DNA and antibodies to Ehrlichia spp. in samples of blood bank donors in Costa Rica using molecular and serological techniques. Presence of Ehrlichia canis was determined in 10 (3.6%) out of 280 blood samples using polymerase chain reaction (PCR) targeting the ehrlichial dsb conserved gene. Analysis of the ehrlichial trp36 polymorphic gene in these 10 samples revealed substantial polymorphism among the E. canis genotypes, including divergent tandem repeat sequences. Nucleotide sequences of dsb and trp36 amplicons revealed a novel genotype of E. canis in blood bank donors from Costa Rica. Indirect immunofluorescence assay (IFA) detected antibodies in 35 (35%) of 100 serum samples evaluated. Thirty samples showed low endpoint titers (64-256) to E. canis, whereas five sera yielded high endpoint titers (1024-8192); these five samples were also E. canis-PCR positive. These findings represent the first report of the presence of E. canis in humans in Central America. Copyright © 2016 Elsevier GmbH. All rights reserved.

Donating umbilical cord blood to a public bank or storing it in a private bank: knowledge and preference of blood donors and of pregnant women.

Umbilical cord blood (UCB) is a source of stem cells for allogeneic haematopoietic transplantation in paediatric and adult patients with haematological malignancies and other indications. Voluntary donation is the basis for the success of unrelated UCB transplantation programmes. In the last few years a growing number of private banks offer their services to expectant parents, to store UCB for future use. The debate concerning UCB donation and private preservation has been ongoing for several years. The aims of this single centre study were to explore knowledge about UCB stem cells and attitudes towards voluntary UCB donation or private UCB preservation among both blood donors and pregnant women. This study was conducted at the "Sapienza" University of Rome. Two types of anonymous questionnaires were prepared: one type was administered to 1,000 blood donors while the other type was distributed to 300 pregnant women. Most blood donors as well as the majority of pregnant women had some general knowledge about UCB (89% and 93%, respectively) and were aware of the possibility of donating it (82% and 95%). However, the level of knowledge regarding current therapeutic use resulted generally low, only 91 (10%) among informed blood donors and 69 (31%) among informed pregnant women gave a correct answer. The survey revealed a preference for voluntary donation both among blood donors (76%) and among pregnant woman (55%). Indeed, a minority of blood donors (6.5%) and of pregnant women (9%) would opt to store UCB for private use. The study raises the following considerations: (i) the large support for UCB donation expressed by blood donors and by pregnant women suggests that UCB preservation does not represent an obstacle to the expansion of UCB donation and to development of unrelated transplantation programmes; (ii) information about UCB donation and preservation should be carefully given by professionals and institutions.

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

Among the principal constraints for SME lending is the lack of SME transparency, poor credit information from credit registries and bureaus, and weak creditor rights. If constraints can be addressed, lending can potentially reach bank targets of 21 percent. State banks still play an important role in financing SMEs in the MENA region, but they use less sophisticated risk management systems than private banks. On another hand, credit guarantee schemes are a popular form of support to SME finan...

We investigated characteristics (scales and composition) of soil seed banks at eight study sites in the rocky mountain region of Beijing by seed identification and germination monitoring.We also surveyed the vegetation communities at the eight study sites to explore the role of soil seed banks in vegetation restoration.The storage capacity of soil seed banks at the eight sites ranked from 766.26 to 2461.92 seedsm-2.A total of 23 plant species were found in soil seed banks,of which 63-80％of seeds were herbs in various soil layers and 60％ of seeds were located in the soil layer at 0-5 cm depth.Biodiversity indices indicated clear differences in species diversity of soil seed banks among different plant communities.The species composition of aboveground vegetation showed low similarity with that based on soil seed banks.In the aboveground plant community,the afforestation tree species showed high importance values.The plant species originating from soil seed banks represented natural regeneration,which also showed relatively high importance values.This study suggests that in the rocky mountain region of Beijing the soil seed banks played a key role in the transformation from pure plantation forest to near-natural forest,promoting natural ecological processes,and the role of the seed banks in vegetation restoration was important to the improvement of ecological restoration methods.

Several Cord Blood (CB) Bank studies suggested that ethnicity impaired CB unit (CBU) qualification. The Bone Marrow Donors Worldwide registries present an over-representation of unrelated donors (UD) from Northwestern European descent. This raises the question of equality of access to hematopoietic stem cells transplant, especially in the Mediterranean zone, which has taken in many waves of immigration. The aim of our study is to address whether, in the Marseille CB Bank, CBU qualification rate is impaired by geographic origin. The study compared biological characteristics of 106 CBU disqualified for total nucleated cell (TNC) count (dCBU) and 136 qualified CBU in relation to registry enrichment and haplotype origin. A high proportion (>80%) of both dCBU and CBU had at least one non-European haplotype and enrich CB and UD registries to a higher extent than those with two European haplotypes (Pdiverse Mediterranean origins do not have an impact on the CBU qualification rate. Partnership with Mediterranean birth clinics with highly trained staff is a reasonable option to increase the HLA diversity of CB Bank inventories and to improve the representation of minorities.

Full Text Available The present paper measured overall technical efficiency of Islamic banks operating in the MENA region during the financial crisis of 2007-2009 to address the question what are the levels of overall, pure technical and scale efficiency of Islamic banks operating in the MENA region and how they evolved during the financial crisis. This paper addresses this question technical, pure technical, and scale efficiency measures are analyzed by employing on-parametric technique, Data Envelopment Analysis (DEA. The study results suggested that Islamic banks in other MENA countries and North Africa on an average are relatively technically inefficient. This might be due to the underdeveloped banking system in those countries. In addition, the decomposition of technical efficiency into pure technical and scale efficiency shows that on average, the Islamic banks in North Africa counties and other MENA counties are having problems in the allocation of resources between their inputs and outputs mix compare to Islamic banks in GCC.

More than 35 000 umbilical cord blood (UCB) transplants have been performed worldwide, prompting the development of private and public banks to collect and store UCB cells. We hypothesized that pediatricians, who are uniquely poised to discuss UCB banking (UCBB) during prenatal or sibling visits, rarely do so. Through distribution of a 26-question electronic survey to general and subspecialty pediatric providers, we assessed baseline knowledge and conversations about UCBB. A total of 473 providers completed the survey; only 22% of physicians ever discussed UCBB with expectant parents. The majority responded that autologous UCB transplants were indicated in malignant (73%) and nonmalignant (61%) conditions; however, these are rare indications. Providers practicing >10 years were more likely to address UCBB ( P ≤ .001), whereas younger and female general pediatric providers were significantly less likely ( P < .001). Overall, pediatric providers rarely speak to families about UCBB, and we believe that they can be better informed to its current clinical utility.

In recent years, the role of donor blood has taken an important place in epidemiology of Leishmaniasis. According to the WHO, the numbers of patients considered as symptomatic are only 5-20% of individuals with asymptomatic leishmaniasis. In this study for detection of Leishmania infection in donor blood samples, 343 samples from the Capa Red Crescent Blood Center were obtained and primarily analyzed by microscopic and serological methods. Subsequently, the traditional culture (NNN), Immuno-chromatographic test (ICT) and Polymerase Chain Reaction (PCR) methods were applied to 21 samples which of them were found positive with at least one method. Buffy coat (BC) samples from 343 blood donors were analyzed: 15 (4.3%) were positive by a microculture method (MCM); and 4 (1.1%) by smear. The sera of these 343 samples included 9 (2.6%) determined positive by ELISA and 7 (2%) positive by IFAT. Thus, 21 of (6.1%) the 343 subjects studied by smear, MCM, IFAT and ELISA techniques were identified as positive for leishmaniasis at least one of the techniques and the sensitivity assessed. According to our data, the sensitivity of the methods are identified as MCM (71%), smear (19%), IFAT (33%), ELISA (42%), NNN (4%), PCR (14%) and ICT (4%). Thus, with this study for the first time, the sensitivity of a MCM was examined in blood donors by comparing MCM with the methods used in the diagnosis of leishmaniasis. As a result, MCM was found the most sensitive method for detection of Leishmania parasites in samples obtained from a blood bank. In addition, the presence of Leishmania parasites was detected in donor bloods in Istanbul, a non-endemic region of Turkey, and these results is a vital importance for the health of blood recipients.

Umbilical cord blood banking in the worldwide hematopoietic stem cell transplantation system: perspectives for Ukraine.

Science.gov (United States)

Kalynychenko, T O

2017-09-01

Significant progress in the promotion of procedural technologies associated with the transplantation of hematopoietic stem cells caused a rapid increase in activity. The exchange of hematopoietic stem cells for unrelated donor transplantations is now much easier due to the relevant international professional structures and organizations established to support cooperation and standard setting, as well as rules for the functioning of both national donor registries and cord blood banks. These processes are increasing every year and are contributing to the outpacing rates of development in this area. Products within their country should be regulated by the competent government authorities. This study analyzes the work of international and national levels of support for transplantation activity in the field of unrelated hematopoietic stem cell transplantation, the standardization order of technologies, as well as data that justify the need to create a network of donated umbilical cord blood banks in Ukraine as a factor in the development of allogeneic transplantation. This will promote the accessibility of international standards for the treatment of serious diseases for Ukrainian citizens.

Full Text Available Introduction: Thalassemia is one of the most common genetic disorder of hemoglobin synthesis in Jammu region. Although RBC transfusion is life saving for these patients, it may be associated with some complications like RBC alloimmunization. Thus, the aim of this study was to determine the frequency of alloimmunization and the most common alloantibodies involved. Material and Methods: This was a descriptive study involving a total of 70 thalassemic patients in the age range of 2-17 years receiving regular blood transfusions, registered at SMGS Blood Bank, Jammu. Relevant clinical and laboratory data was collected with reference to age at the start of transfusions, total number of transfusions received and splenectomy status. Antibodies screening, antibody identification, and cross matching was done on allpatient samples included in the study, during the period between November 2009 and October 2010. Results: In this study, a total of six alloantibodies six patients (8.5% and one autoantibody (1.42% was detected. All identified alloantibodies belonged to Rh system (i.e. anti-E, in 3 patients (50%, anti D, in one patient (16.66% and Kell system (anti-K, in two patients (33.34%. Higher frequency of alloimmunization was found, with increase in number of transfusions and in those who received transfusions after 1 year of age. Alloimmunization was not significantly associated with gender and splenectomy status (P-value > 0.05. Conclusion: Red cell alloantibodies developed in 8.5% of thalassemic patients and 1.42% had autoantibodies. The most common alloantibodies identified were anti Rh system antibodies (anti-E and anti-D present in 50% and 16.66% of patients respectively. Alloimmunization is not an uncommon problem faced by blood banks and finding compatible units for regularly transfused thalassemic patients may become very difficult. In order to reduce alloimmunization, a policy for performing extended red cell phenotyping of these patients is

The human-T cell lymphotropic virus is a retrovirus with various types known so far. HTLV-I and HTLV-II are of clinically importance as they cause different diseases such as adult T-cell leukemia/lymphoma, tropical spastic paraparesis, and human T-lymphotropic virus type I-associated myelopathy (HAM). To estimate the prevalence of presumptive and confirmatory reactivity to HTLV-I/II in blood donors of Hospital Pablo Tobón Uribe Blood Bank between 2014 and 2015. The information was obtained from the Hospital Pablo Tobón Uribe Blood Bank database. We analyzed age, sex, place of origin, and place of residence of donors, and the reactivity using the screening test (ELISA) as well as the confirmatory test (immunoblot). The donor population studied included 6,275 men and 8,148 women, for a total of 14,423 donors recruited between March 1, 2014, and June 30, 2015. Of all tested donors, 25 were positive for HTLV-I/II by the screening test (ELISA). After performing the confirmatory test (immunoblot), only nine patients were positive for HTLV-I/II (36%), of whom eight were reactive to HTLV-I (32%) and one to HTLV-II (4%), for a global seroprevalence of 0.06% (CI 95%: 0.10-0.25). Our findings were consistent with those found in similar studies in non-endemic areas of the country and with those from studies at international level reported in the literature.

BACKGROUND: Umbilical cord blood (UCB) has successfully used for transplantation to treat hematologic malignancies and genetic diseases. Herein, we describe the experience generated in a single public UCB bank at Zhejiang Province in China. METHODS: Good manufacturing practice and standard operating procedures were used to address donor selection as well as UCB collection, processing, and cryopreservation. Total nucleated cells (TNCs), cellular viability, CD34+ cells, and colony-forming units were determined, and infectious diseases screening test, sterility test, and HLA typing for UCB units were done. RESULTS: Only 18.51% of all collected UCB units met storage criteria, and 7,056 UCB units were cryopreserved in 10 years. The volume of UCB units was 95.0 ± 22.0 ml. The number of TNCs before and after processing was 13.32 ± 3.63 × 10(8) and 10.63 ± 2.80 × 10(8), respectively, and the recovery rate was 80.71 ± 11.26%. 0.4344 ± 0.1874% of the TNCs were CD34+ cells. The CFU-GM was 32.1 ± 28.0 colonies per 1 × 10(5) nucleated cells. Based mainly on HLA and nucleated cell content, 26 UCB units were released for transplantation. CONCLUSIONS: A public UCB bank was successfully established in China; collection and processing of UCB units should be optimized in order to gain maximum volume and cell count.

The development of effective cryopreservation techniques for both red blood cells and platelets, which maintain ex vivo biological activity, in combination with frozen plasma, provides for a unique blood banking strategy. This technology greatly enhances the storage life of these products. The rationale and potential advantages of using cryopreservation techniques for the provision of blood products to remote and military environments have been effectively demonstrated in several conflicts over the last decade. Current haemostatic resuscitation doctrine for the exsanguinating patient supports the use of red blood cells, platelets and frozen plasma early in the resuscitation. We believe an integrated fresh-frozen blood bank inventory could facilitate provision of blood products, not only in the military setting but also in regional Australia, by overcoming many logistic and geographical challenges. The processes involved in production and point of care thawing are sufficiently well developed and achievable to make this technology a viable option. The potential limitations of cryopreservation and subsequent product thawing need to be considered if such a strategy is to be developed. A substantial body of international experience using cryopreserved products in remote settings has already been accrued. This experience provides a template for the possible creation of an Australian integrated fresh-frozen blood bank inventory that could conceivably enhance the care of patients in both regional Australia and in the military setting.

Full Text Available Sickle cell disease and homozygous β-thalassaemia are common haemoglobinopathies in Oman, with many implications for local healthcare services. The transfusions of such patients take place in many hospitals throughout the country. Indications for blood transfusions require local recommendations and guidelines to ensure standardised levels of care. This article summarises existing transfusion guidelines for this group of patients and provides recommendations for blood banks and transfusion services in Oman. This information is especially pertinent to medical professionals and policy-makers developing required services for the standardised transfusion support of these patients.

Vital tissue provided by fresh frozen tissue banking is often required for genetic tumor profiling and tailored therapies. However, the potential patient benefits of fresh frozen tissue banking are currently limited to university hospitals. The objective of the present pilot study--the first one in the literature--was to evaluate whether fresh frozen tissue banking is feasible in a regional hospital without an integrated institute of pathology. Patients with resectable breast and colon cancer were included in this prospective study. Both malignant and healthy tissue were sampled using isopentan-based snap-freezing 1 h after tumor resection and stored at -80 °C before transfer to the main tissue bank of a University institute of pathology. The initial costs to set up tissue banking were 35,662 US$. Furthermore, the running costs are 1,250 US$ yearly. During the first 13 months, 43 samples (nine samples of breast cancer and 34 samples of colon cancer) were collected from 41 patients. Based on the pathology reports, there was no interference with standard histopathologic analyses due to the sample collection. This is the first report in the literature providing evidence that tissue banking in a regional hospital without an integrated institute of pathology is feasible. The interesting findings of the present pilot study must be confirmed by larger investigations.

The prevalence of toxoplasma gondii (T.g) infection in blood donors has been poorly studied. The aim of this study was to assess the prevalence of acute and chronic toxoplasmosis in blood products. A total of 223 blood products (101 fresh frozen plasma (FFP) and 122 packed cells (PC)) in Imam Reza hospital blood bank, Tehran, Iran were tested for specific T.g antibodies (IgG and IgM) by ELISA method. Positive IgG anti-T.g samples were further tested for IgM anti-T.g. A positive IgG test with the negative and positive IgM test was interpreted as a chronic and acute toxoplasmosis respectively. Of 223 samples 38.6% and 0.45% were positive for IgG anti-T.g and IgM anti-T.g levels respectively. Therefore, one and 85 samples were involved acute and chronic toxoplasmosis respectively. Twenty-six of fresh frozen plasma samples were positive for IgG anti-T.g and one of them was positive for IgM anti-T.g. Sixty packed cell samples were positive for IgG anti-T.g. Our study showed that there were chronic and acute toxoplasmosis in blood products and the prevalence of toxoplasmosis especially chronic form was high. Therefore screening of blood for T.g antibodies may be considered. Copyright © 2014 Elsevier Ltd. All rights reserved.

Early transient incapacitation (ETI) is the complete cessation of performance during the first 30 min after radiation exposure and performance decrement (PD) is a reduction in performance at the same time. Supralethal doses of radiation have been shown to produce a marked decrease in regional cerebral blood flow in primates concurrent with hypotension and a dramatic release of mast cell histamine. In an attempt to elucidate mechanisms underlying the radiation-induced ETI/PD phenomenon and the postradiation decrease in cerebral blood flow, primates were exposed to 100 Gy (1 Gy = 100 rads), whole-body, gamma radiation. Pontine and cortical blood flows were measured by hydrogen clearance, before and after radiation exposure. Systemic blood pressures were determined simultaneously. Systemic arterial histamine levels were determined preradiation and postradiation. Data obtained indicated that radiated animals showed a decrease in blood flow of 63% in the motor cortex and 51% in the pons by 10 min postradiation. Regional cerebral blood flow of radiated animals showed a slight recovery 20 min postradiation, followed by a fall to the 10 min nadir by 60 min postradiation. Immediately, postradiation systemic blood pressure fell 67% and remained at that level for the remainder of the experiment. Histamine levels in the radiated animals increased a hundredfold 2 min postradiation. This study indicates that regional cerebral blood flow decreases postradiation with the development of hypotension and may be associated temporally with the postradiation release of histamine

VDRL (75.0%) tests (P public system does not include human T-cell lymphotropic virus testing; this is reserved for the population from endemic zones. In northeastern Italy current legislation prevents the establishment of private fee-based banks for storage of CB-SC. The cryopreservation, for future autologous personal or family use, is possible only by sending to foreign private banks, with a further fee of €300. These regulations confirm that Italian legislation tries to increase the anonymous allogenic donations and the number of CB-CS bags stored in the free-cost public system, that are available to anyone with therapeutic needs. Private banking is used almost exclusively by the wealthier local population. In the public system, many physicians continue to use older Italian laws regarding syphilis diagnosis, and NRBC interference on WBC count may have an impact on cord blood harvesting. Our findings suggest that in the EU there is no consensus policy on donor management. The value of storage for potential use within the family is useful only with collaboration between the public and the private systems.

Umbilical cord cell banking-implications for the future

International Nuclear Information System (INIS)

Gunning, Jennifer

2005-01-01

The first successful cord cell transplant to a sibling with Fanconi's anaemia took place 15 years ago. This proven utility of cord blood led to the establishment of cord blood banks both private and public and there are now nearly 100 cord blood banks worldwide. It is estimated that over 200,000 cord blood units (CBU) are held by the private sector and over 160,000 CBU are registered with the largest public cord blood registry. There is a tension between private cord blood banks, which store CBU for autologous or family use, and public banks, which store CBU for unrelated use and the ethics of private cord blood storage has been questioned. But more general ethical questions also arise regarding ownership, consent, confidentiality, costs and quality standards and patenting. In looking at these ethical issues one also needs to look at potential future use of cord blood stem cells. Up until now cord cells have principally been used in the treatment of paediatric blood and immune disorders. Improvements in cell expansion technology will make CBU more appropriate also for treating adults with such disorders. However, it has also been demonstrated that cord blood stem cells have the capacity to differentiate into other types of cells, neuronal, bone, epithelial and muscle which would have a future role to play in cell therapy and regenerative medicine

Over the past decade umbilical cord blood (UCB) has been increasingly used as a source of haematopoietic stem cells (HSCs) for patients who require a HSC transplant but do not have an HLA-matched donor. It was anticipated that using UCB as an alternative source of HSCs would increase the chance of finding a donor, particularly for the otherwise underrepresented ethnic minority groups. To evaluate the effectiveness of the Australian public UCB banks to increase the ethnic diversity of available HSC donations, this paper analyses the ethnic diversity of the Sydney Cord Blood Bank (SCBB), comparing this diversity to that of the Australian Bone Marrow Donor Registry (ABMDR). It also examines the ethnic diversity of those patients who, after requesting a haematopoietic stem cell transplantation in the 2-year period between 2003 and 2005, managed to find a suitably matched bone marrow or UCB donor. We show that the ethnic mix of donors to the SCBB has remained generally broad in source, is comparative to the Australian population, and is more diverse than the ABMDR. This, however, may still not be sufficient to substantially increase the likelihood of finding a donor for some ethnic minority groups.

Objective: To determine the frequency of HIV, HBV, HCV, syphilis and malaria in blood donors at Children Hospital and Institute of Child Health (ICH), Lahore and compare with other local and international published data. Study Design: Descriptive study. Place and Duration of Study: This was conducted at the blood bank of Children's Hospital and ICH, Lahore from October 2015 to February 2016. Patient and Methods: All adult male blood donors who had donated blood during above mentioned period, between 18 to 55 years of age were included in this study. Each and every donor was subjected to a predetermined, prepared questionnaire to find out their eligibility for donation. All blood donors' serum samples were screened for HBsAg, Anti-HCV, syphilis, HIV and malaria by immuno chromatography technique according to manufacturer instruction. Results: Statistical analysis showed that out of 10,048 blood donors, 7.94 percent (n=798) were infected with any one of the above mentioned diseases and 92.05 percent (n=9,250) had no infection. The overall frequency of HBsAg, HCV, HIV, syphilis and malaria were found to be 1.59 percent, 3.75 percent, 0.11 percent, 2.08 percent and 0.39 percent respectively. The co-infections of HCV + Syphilis, HBsAg + HCV, HBsAg + Syphilis, HCV + malarial parasite (M.P) and HBsAg + HIV + syphilis was 0.12 percent, 0.11 percent, 0.01 percent and 0.0099 percent respectively. Conclusion: There is a decreasing trend of HBsAg, HCV infections but increasing trend of HIV and syphilis infections in blood donors that is an alarming situation. (author)

Seventy-six schizophrenic patients were examined by a Xe-133 inhalation method to determine regional cerebral blood flow. A decreased blood flow was observed in the frontal lobe, especially in the right inferior part. In a study on the relationship between disease subtypes and regional cerebral blood flow, negative symptoms were found more predominantly associated with dissolution type than delusion type. In the group of dissolution type, a decreased blood flow was observed in both the right inferior frontal lobe and the right upper hemisphere, in comparison to the group of delution type. Patients presenting with auditory hallucination had a significantly higher incidence of both negative and positive symptoms, as compared with those not presenting with it. In such patients, a significantly decreased blood flow was also seen in the left upper frontal lobe and the bilateral parietal lobe. Xe-133 inhalation method should assist in evaluating brain function in schizophrenic patients, thus leading to the likelihood of developing a new treatment modality. (N.K.)

2009-12-01

Full Text Available Dynamic development of financial industry in some last ten years that, considering the kind of financial agents, remained bank-oriented represents a suficient reason to investigate the causes that brought to the present structure of banking system. After having presented theoretical bases of the integration forms and banks connection, the paper analyzes the influence of foreign banks on the development of Croatian bank system. Thus, beside the knowledge of quantitative changes in the banking system, the paper researched the motivations of the banks regarding integration that, among other things, brought to creating the effects of scale and scope economies. However, the concentrations among banks can lead to creation of negative externalities that later become potential dangers for the banking. Pre-cognitions on development of banking system are used to create projection of future banking development while the data basis of the countries from the region enabled the comparative analysis of banks integration in these countries. The conclusion is that the foreign banks have been the largest promoters of bank integration in the Republic of Croatia contributing also to qualitative development of banking market and to deepening of financial market spectrum.

Changes in Quantitative Indicators of Concentration in the Countries of this Region during the Transformation Period of Banking Systems

Full Text Available The reshaping processes of the banking systems in the countries of this region that involved the reorganization and restructuring of insolvent banks as well as the privatization of the state banks were aimed at setting up a framework within which banks would operate according to the modern market principles. With the opening of the banking market to foreign capital, the foreign banks have gained access to the banking market and have over a ten-year period significantly increased their market share. Due to the existing barriers to entry into the market, foreign-owned banks tended to use the strategy of buying shares in already-established banks rather than starting up a new bank. Comparisons between concentration indicators showed that there are differences among countries and mostly these differences result from the differences in the size of the banking systems and the size of national economies. Still, the values of quantitative indicators of concentration in countries with larger banking systems are lower than in countries with fewer banks.

Full Text Available Background: Cold agglutinins (CA are benign naturally occurring low titer autoantibodies present in most individuals. Those with moderate strength are found in infections, malignancies or autoimmune conditions with diagnostic importance. Aim: Present report deals with CA that brought spontaneous hemagglutination in blood units stored at 2-6°C. Study design: Over 32 months period between July 1993 and December 1995, blood units were inspected for spontaneous cold auto-hemagglutination (SpCA phenomenon. The plasma from these units was separated and investigated for serological specificity using in house red cell panel and standard serological methods. Results: Among 51,671 blood units, 112 units showed SpCA phenomenon. A rising trend seen in first half of study period significantly fell in remaining half. Specificities of the antibodies detected include anti-I (27, anti-i (53, anti-Pr (21 with remaining few being undetermined specificity. Absorption of serum using enzyme-treated red cells revealed a presence of anti-Pr among the cases, the two of which with new specificities that reacted preferentially with red cells from either new-born or adults and were tentatively named as anti-Pr Fetal and anti-Pr adult , respectively. While 9 cases showed optimum reaction at neutral pH of 7, 68 (62% cases reacted at pH 5.8 through 8.0, 28 (26% cases preferred an acidic pH 5.8 and 4 cases opted an alkaline pH 8. Of 28 cases with antibodies preferentially reacting in acidic medium, 17 (60% cases were anti-i and 7 (25% cases were anti-Pr. Conclusion: Unique SpCA phenomenon observed in blood units stored under blood bank conditions seems to be due to CA developed in response to vector-borne infectious agents. Majority of the cases displayed their specificities, otherwise are rare to be encountered.

Regional cerebral blood flow (rCBF) was measured at rest using the 133 Xe inhalation technique in 40 DSM-III-diagnosed schizophrenics (22 males, 18 females: mean age 35.0 years, range 20-49 years) and 31 age-and sex-matched normal controls (16 males, 15 females: mean age 34.3 years, range 21-49 years). The absolute value (AV) and the percent value (PV) of the rCBF in schizophrenics were compared with those in controls. Correlations between rCBF and the Brief Psychiatric Rating Scale (BPRS) scores or the performance of Wisconsin Card Sorting Test (WCST) were examined in schizophrenics. Schizophrenics showed significantly lower AVs in all brain regions examined and a significantly lower PV in the left superior frontal region than controls. The hyperfrontal rCBF distribution which was found in both hemispheres in controls, was absent in the left hemisphere in schizophrenics. In schizophrenics, superior frontal blood flows were significantly negatively correlated with the negative symptom scores of the BPRS but not with the total scores and the positive symptom scores of the BPRS. In schizophrenics, inferior frontal blood flows were significantly correlated with the number of sorting categories achieved. These results indicate that rCBF in schizophrenia is reduced in the whole brain and especially in the left superior frontal region. These findings suggest a frontal lobe dysfunction in schizophrenia.

Regional CBF (rCBF) and regional cerebral blood volume (rCBV) were evaluated by N,N,N'-trimethyl-N'-(2)-hydroxy-3-methyl-5-[123I]iodobenzyl-1, 3-propanediamine-2 HCl- and /sup 99m/TC-labeled red blood cells, respectively, and single-photon emission computerized tomography (SPECT) in a patient with focal cerebral ischemia. Sequential transmission computerized tomography (TCT) and SPECT functional data were compared with clinical findings to monitor the pathophysiological events occurring in stroke. A lack of correlation between rCBF-rCBV distributions and blood-brain barrier (BBB) breakdown was found in the acute phase. In the face of more prolonged alteration of BBB, as seen by TCT enhancement, a rapid evolution of transient phenomena such as luxury perfusion was shown by SPECT studies. Follow-up of the patient demonstrated a correlation between the neurological recovery and a parallel relative improvement of the cerebral perfusion

In total, 4502 units of cord blood (CB) were collected during a 2-year period from 2005 to 2006 by the Buddhist Tzu-Chi Stem Cells Center. The aim of this study was to analyze the incidence of microbial contamination and type of organism present in the cord blood. The clinical impact of microbial contamination on hematopoietic progenitor cell (HPC) grafts used for HPC transplantation is also discussed. First and second specimens were obtained for microbial assessment. These were collected in laboratory after cord blood collection and after cord blood unit manipulation, respectively. The samples were cultured and the results reviewed. The overall incidence of microbiological contamination was 1.8% (82/4502). Three CB units were contaminated with two different organisms. Infectious organisms comprised 9.4% (8/85) of total isolated microbes. These infectious microorganisms were beta-Streptococci group B, Candida tropicalis and Staphylococcus aureus which were isolated in 6, 1 and 1 of CB units respectively. Escherichia coli, Bacteroides fragilis, Lactobacillus spp., Enterococcus, beta-Streptococcus Group B, Bacteroides valgatus, Corynebacterium spp., Klebsiella pneumonia and Peptococcus spp. were the most frequently encountered microorganisms. A higher contamination rate of the CB units was noted after vaginal delivery (2.16%) compared to caesarian section (0.85%) (p bank, we use a closed system but an in utero method. Similar to other studies, most of microorganisms reported here as contaminants are non-pathogenic.

Determination of background radiation dose-rate is important in the process of assessing risks to the environment from exposure to living organisms both in terms of deriving the incremental dose-rate and as a point of reference for evaluating the significance of the exposure level. In the present study, 210 Po was quantified in two species of bivalve mollusks commonly available from so called a 'wedge bank region' of southern tip of India. Based on the activity concentration in media and in the whole body, an external and internal dose rate assessment to green mussel Perna viridis and brown mussel Perna indica due to 210 Po was derived using ERICA assessment tool. The samples were collected at the intertidal region along the wedge bank region of southern tip of India during 2009 to 2010. The measurement contributes to a better knowledge of these elements, since no data exists in this region. 5-10 g of each tissue sample was wet-digested using 70% concentrated HNO 3 followed by the addition of 40% H 2 O 2 along with 20 8Po tracer (0.2 Bq). The normality of the data set was checked using Lilliefors test (ne''50) and potential outliers, if any, were tested using Walsh's test (n>60). Using the measured 210 Po activity in molluscs, sediments and seawater, dose assessment was performed using the Tier 2 ERICA environment dose assessment tool 1.0

Fluorescence Exclusion: A Simple Method to Assess Projected Surface, Volume and Morphology of Red Blood Cells Stored in Blood Bank

Directory of Open Access Journals (Sweden)

Camille Roussel

2018-05-01

Full Text Available Red blood cells (RBC ability to circulate is closely related to their surface area-to-volume ratio. A decrease in this ratio induces a decrease in RBC deformability that can lead to their retention and elimination in the spleen. We recently showed that a subpopulation of “small RBC” with reduced projected surface area accumulated upon storage in blood bank concentrates, but data on the volume of these altered RBC are lacking. So far, single cell measurement of RBC volume has remained a challenging task achieved by a few sophisticated methods some being subject to potential artifacts. We aimed to develop a reproducible and ergonomic method to assess simultaneously RBC volume and morphology at the single cell level. We adapted the fluorescence exclusion measurement of volume in nucleated cells to the measurement of RBC volume. This method requires no pre-treatment of the cell and can be performed in physiological or experimental buffer. In addition to RBC volume assessment, brightfield images enabling a precise definition of the morphology and the measurement of projected surface area can be generated simultaneously. We first verified that fluorescence exclusion is precise, reproducible and can quantify volume modifications following morphological changes induced by heating or incubation in non-physiological medium. We then used the method to characterize RBC stored for 42 days in SAG-M in blood bank conditions. Simultaneous determination of the volume, projected surface area and morphology allowed to evaluate the surface area-to-volume ratio of individual RBC upon storage. We observed a similar surface area-to-volume ratio in discocytes (D and echinocytes I (EI, which decreased in EII (7% and EIII (24%, sphero-echinocytes (SE; 41% and spherocytes (S; 47%. If RBC dimensions determine indeed the ability of RBC to cross the spleen, these modifications are expected to induce the rapid splenic entrapment of the most morphologically altered RBC

The present study on schizophrenics dealt with the relationship of regional cerebral blood flow (rCBF) to age, disease duration, and treatment length with chlorpromazine hydrochloride (CPZ). Regional cerebral blood flow in 28 cerebral regions of interest was measured by iv injection of X-133 in 54 schizophrenic patients and 39 healthy volunteers. Neither age nor dosage of CPZ significantly influenced rCBF. All patients, including 11 treated for a short period of time (6 months or less), were characterized by having a decreased rCBF over the whole cerebrum. Thirty-four patients treated for a long period of time (2 years or more) had a varied rCBF distribution in the left hemisphere, with the most predominant feature being the decrease in rCBF in the frontal lobe (i.e., ''hypofrontality''); however, there was no linear correlation between rCBF and disease duration. A decreased rCBE in the right occipital region was seen in patients with paranoid schizophrenia, suggesting that manifestations of symptoms may depend on disturbed regions. These results suggest that cerebral dysfunction in schizophrenic patients may not be restricted to the frontal lobe, but cover the whole cerebrum, and that nonuniform dysfunction in various regions of the cerebrum, including the frontal lobe, may be involved in manifestations of symptoms.

As part of our ongoing H II Region Discovery Survey (HRDS), we report the Green Bank Telescope detection of 148 new angularly large Galactic H II regions in radio recombination line (RRL) emission. Our targets are located at a declination of δ > -45^\\circ , which corresponds to 266^\\circ > {\\ell }> -20^\\circ at b=0^\\circ . All sources were selected from the Wide-field Infrared Survey Explorer Catalog of Galactic H II Regions, and have infrared angular diameters ≥slant 260\\prime\\prime . The Galactic distribution of these “large” H II regions is similar to that of the previously known sample of Galactic H II regions. The large H II region RRL line width and peak line intensity distributions are skewed toward lower values, compared with that of previous HRDS surveys. We discover seven sources with extremely narrow RRLs 100 {pc}, making them some of the physically largest known H II regions in the Galaxy. This survey completes the HRDS H II region census in the Northern sky, where we have discovered 887 H II regions and more than doubled the size of the previously known census of Galactic H II regions.

Ireland, Lynette; McKelvie, Helen

2003-01-01

The legal structure for the regulation of tissue banking has existed for many years. In Australia, the donation of human tissue is regulated by legislation in each of the eight States and Territories. These substantially uniform Acts were passed in the late 1970's and early 1980's, based on model legislation and underpinned by the concept of consensual giving. However, it was not until the early 1990's that tissue banking came under the notice of regulatory authorities. Since then the Australian Government has moved quickly to oversee the tissue banking sector in Australia. Banked human tissue has been deemed to be a therapeutic good under the Therapeutic Goods Act 1989, and tissue banks are required to be licensed by the Therapeutic Goods Administration and are audited for compliance with the Code of Good Manufacturing Practice- Human Blood and Tissues. In addition, tissue banks must comply with a myriad of other standards, guidelines and recommendations.

Regional cerebral blood flow (r-CBF) of 10 pregnant women were quantified by 133 Xe SPECT study with inhalation method before and after artificial abortion. During pregnancy, value of r-CBF in each region except occipital lobe was significantly higher than that of the post abortion. Arterial blood gas was analyzed after SPECT procedure. P co2 concentration increased significantly after artificial abortion. Although its mechanism is unknown, our preliminary work demonstrates that r-CBF increased by pregnancy. (author)

Establishment of an unrelated umbilical cord blood bank qualification program: ensuring quality while meeting Food and Drug Administration vendor qualification requirements.

Qualification of a cord blood bank (CBB) is a complex process that includes evaluation of multiple aspects of donor screening and testing, processing, accreditation and approval by professional cell therapy groups, and results of received cord blood units. The University of Minnesota Medical Center Cell Therapy Laboratory has established a CBB vendor qualification process to ensure the CBB meets established regulatory and quality requirements. The deployed qualification of CBBs is based on retrospective and prospective review of the CBB. Forty-one CBBs were evaluated retrospectively: seven CBBs were disqualified based on failed quality control (QC) results. Eight CBBs did not meet the criteria for retrospective qualification because fewer than 3 cord blood units were received and the CBB was not accredited. As of March 2012, three US and one non-US CBBs have been qualified prospectively. One CBB withdrew from the qualification process after successful completion of the comprehensive survey and subsequent failure of the provided QC unit to pass the minimum criteria. One CBB failed the prospective qualification process based on processing methods that were revealed during the paper portion of the evaluation. A CBB qualification process is necessary for a transplant center to manage the qualification of the large number of CBBs needed to support a umbilical cord blood transplantation program. A transplant center that has utilized cord blood for a number of years before implementation of a qualification process should use a retrospective qualification process along with a prospective process. © 2013 American Association of Blood Banks.

Efficiency Analysis of Islamic Banks in the Middle East and North Africa Region: A Bootstrap DEA Approach

Directory of Open Access Journals (Sweden)

Raéf Bahrini

2017-02-01

Full Text Available This paper measures and analyzes the technical efficiency of Islamic banks in the Middle East and North Africa (MENA region during the period 2007–2012. To do this, the bootstrap Data Envelopment Analysis (DEA approach was employed in order to provide a robust estimation of the overall technical efficiency and its components: pure technical efficiency and scale efficiency in the case of MENA Islamic banks. The main results show that over the period of study, pure technical inefficiency was the main source of overall technical inefficiency instead of scale inefficiency. This finding was confirmed for all MENA Islamic banks as well as for the two subsamples: Gulf Cooperation Council (GCC and non-GCC Islamic banks. Furthermore, our results show that GCC Islamic banks had stable efficiency scores during the global financial crisis (2007–2008 and in the early post-crisis period (2009–2010. However, a decline in overall technical efficiency of all panels of MENA Islamic banks was recorded in the last two years of the study period (2011–2012. Thus, we recommend that MENA Islamic bank managers focus more on improving their management practices rather than increasing their sizes. We also recommend that financial authorities in MENA countries implement several regulatory and financial measures in order to ensure the development of MENA Islamic banking.

Full Text Available The human lymphotropic viruses type I (HTLV-I and type II (HTLV-II are members of a group of mammalian retroviruses with similar biological properties, and blood transfusion is an important route of transmission. HTLV-I is endemic in a number of different geographical areas and is associated with several clinical disorders. HTLV-II is endemic in several Indian groups of the Americas and intravenous drug abusers in North and South America, Europe and Southeast Asia. During the year of 1995, all blood donors tested positive to HTLV-I/II in the State Blood Bank (HEMOPA, were directed to a physician and to the Virus Laboratory at the Universidade Federal do Pará for counselling and laboratory diagnosis confirmation. Thirty-five sera were tested by an enzyme immune assay, and a Western blot that discriminates HTLV-I and HTLV-II infection. Two HTLV-II positive samples were submitted to PCR analysis of pX and env genomic region, and confirmed to be of subtype IIa. This is the first detection in Belém of the presence of HTLV-IIa infection among blood donors. This result emphasizes that HTLV-II is also present in urban areas of the Amazon region of Brazil and highlights the need to include screening tests that are capable to detect antibodies for both types of HTLV.

Using positron emission tomography with 15 O-labelled CO 2 , O 2 and CO gases, the effects of glycerol on regional cerebral blood flow (CBF), blood volume (CBV) and oxygen metabolism (CMRO 2 ) were investigated in 6 patients with meningioma accompanying peritumoral brain edema. The same study was done in 5 normal volunteers. The changes of blood gases, hematocrit and hemoglobin were also examined. After a drip infusion of glycerol, the regional CBF increased not only in the peritumoral cortex and white matter but also in the intact cortex and white matter on the contralateral side. The increase of CBF was extensive and substantially there were no regional differences. In contrast, the changes of CMRO 2 were not significant. This was derived from the increase in oxygen extraction fraction throughout extensive areas including the peritumoral area. There were no changes in CBV. Hematocrit and hemoglobin decreased to a small degree. In the normal volunteers, the same findings were noted. Thus, glycerol increases the functional reserve for cerebral oxygen metabolism, not only in the peritumoral regions but also in the intact regions. The effects of glycerol on hemodynamics and metabolism were discussed with reference to some differences from mannitol. (author)

Baseline extracellular potassium level as an indicator of the rate of increase of the same on further storage in CPDA-1 whole blood units: a potential approach to complement FIFO system for prioritisation of blood bags for release from blood-banks.

Potassium levels in stored blood bags increases as they age. Hyperkalemia in transfused blood has undesirable cardiac effects. Within a 19-month period, baseline and weekly samples from 15 CPDA-1 whole blood bags were collected till 28 days of storage and analysed for potassium, sodium, uric acid, albumin and whole blood haemoglobin. One unit increase in baseline (0 day) potassium in extracellular fluid of blood units was associated with the following increases in potassium levels on later days of storage: around two unit increase at 1 week (r2 = 0·50, P values. For CPDA-1 blood bags (i) low baseline potassium blood bags might be preferred for transfusion in cases demanding a low potassium load and (ii) coordinating the ‘first-in-first-out’ (FIFO) policy with ‘early release of blood-bags with high initial potassium’ might be helpful in improving the release of suitable blood units from blood-banks.

Stem cells are highly promising resources for application in cell therapy, regenerative medicine, drug discovery, toxicology and developmental biology research. Stem cell banks have been increasingly established all over the world in order to preserve their cellular characteristics, prevent contamination and deterioration, and facilitate their effective use in basic and translational research, as well as current and future clinical application. Standardization and quality control during banking procedures are essential to allow researchers from different labs to compare their results and to develop safe and effective new therapies. Furthermore, many stem cells come from once-in-a-life time tissues. Cord blood for example, thrown away in the past, can be used to treat many diseases such as blood cancers nowadays. Meanwhile, these cells stored and often banked for long periods can be immediately available for treatment when needed and early treatment can minimize disease progression. This paper provides an overview of the fundamental principles of stem cell banking, including: (i) a general introduction of the construction and architecture commonly used for stem cell banks; (ii) a detailed section on current quality management practices; (iii) a summary of questions we should consider for long-term storage, such as how long stem cells can be stored stably, how to prevent contamination during long term storage, etc.; (iv) the prospects for stem cell banking.

Seroprevalence, cost per donation and reduction in blood supply due to positive and indeterminate results for infectious markers in a blood bank in Lima, Peru

Directory of Open Access Journals (Sweden)

Jeel Moya-Salazar

Full Text Available ABSTRACT Introduction: Safety in Transfusion Medicine is subject to regulations and government legislation within a total quality framework. The aim of this study was to evaluate the impact of seroprevalence and indeterminate results on lost units and cost per donation. Methods: A prospective cross-sectional study was performed in the Blood Bank and Transfusion Therapy Department of the Hospital Central de la Policia Nacional del Perú in Lima, Peru. All completed donations (replacement/voluntary without complications were included in this study. Every donation met the institutional requirements and quality criteria of Programa Nacional de Hemoterapia y Bancos de Sangre (PRONAHEBAS. Data analysis was achieved using the Statistical Package for the Social Sciences. Results: A total of 7723 donations were evaluated during 2014 and 2015 with 493 being seropositive (overall prevalence 5.25% and 502 having indeterminate results (overall prevalence 5.35%. Thus total loss was 995 units, 437.8 L of blood and 49,750 US dollars. The most common seropositive infectious markers were the core antibody of hepatitis B virus (2.82% and syphilis (1.02%, and the most common indeterminate results were Chagas disease (1.27% and the core antibody of hepatitis B virus (1.26%. There was no significant change in the prevalence of seropositivity (p-value = 0.243 or indeterminate results (p-value = 0.227 over the two-year period of the study. A statistical correlation was found between the cost per lost donation and the most prevalent markers (rho = 0.848; p-value = <0.001. Conclusion: Seroprevalence was lower than the regional mean, but the prevalence of indeterminate results was elevated causing a great impact on blood supply and economic losses to this institution.

During the past decade, the use of umbilical cord blood (CB) as a source of transplantable hematopoietic stem cells has been increasing. Little is known about the psychosocial consequences that later affect parents after unrelated CB donation. The objective of this study was to evaluate the attitudes of mothers toward unrelated donation of umbilical CB for transplantation 6 months after giving birth. A prospective study was performed with a standardized, anonymous questionnaire distributed to 131 women 6 months after CB donation. The questionnaire included topics concerning views about the ethical accuracy of having donated CB, emotional responses after donation, concerns about genetic testing and research with CB samples, attitude toward anonymity between her child and possible unrelated CB recipient, and willingness to repeatedly donate umbilical CB in a next pregnancy. The vast majority (96.1%) stated that they would donate umbilical CB again, and all respondents were certain that their decision to have donated umbilical CB was ethical. With regard to the potential risks of genetic testing and "experimentation" of umbilical CB, a significant correlation (p = 0.01) was found between negative attitudes and the decision not to donate umbilical CB again. Additionally, it was observed that women who had a negative experience concerning the donation of CB would not donate again (p = 0.004). This study shows a high degree of satisfaction of unrelated umbilical CB donation for banking in women 6 months after delivery. Despite a well-performed and detailed informed consent procedure, one of the ongoing issues for the donators in CB banking involves the concern regarding of improper use of the cells, such as genetic testing or experimentation. Accurate and detailed counseling of pregnant women and their partners therefore maximizes the likelihood that they will donate CB for unrelated banking. These data provide a basis for the improvement of donor selection procedures

Infection remains a leading cause of post-transfusion mortality and morbidity. Bacterial contamination is, however, detected in less than 0.1% of blood units tested. The aim of the study was to identify viable bacteria in standard blood-pack units, with particular focus on bacteria from the oral cavity, and to determine the distribution of bacteria revealed in plasma and in the red blood cell (RBC)-fraction. Cross-sectional study. Blood were separated into plasma and RBC-suspensions, which were incubated anaerobically or aerobically for 7 days on trypticase soy blood agar (TSA) or blue lactose plates. For identification colony PCR was performed using primers targeting 16S rDNA. Blood donors attending Capital Region Blood Bank, Copenhagen University Hospital, Rigshospitalet, Hvidovre, Denmark, October 29th to December 10th 2013. 60 donors (≥50 years old), self-reported medically healthy. Bacterial growth was observed on plates inoculated with plasma or RBCs from 62% of the blood donations. Growth was evident in 21 (35%) of 60 RBC-fractions and in 32 (53%) of 60 plasma-fractions versus 8 of 60 negative controls (p = 0.005 and p = 2.6x10-6, respectively). Propionibacterium acnes was found in 23% of the donations, and Staphylococcus epidermidis in 38%. The majority of bacteria identified in the present study were either facultative anaerobic (59.5%) or anaerobic (27.8%) species, which are not likely to be detected during current routine screening. Viable bacteria are present in blood from donors self-reported as medically healthy, indicating that conventional test systems employed by blood banks insufficiently detect bacteria in plasma. Further investigation is needed to determine whether routine testing for anaerobic bacteria and testing of RBC-fractions for adherent bacteria should be recommended.

During the years 1994-2001, a progressive decrease of the number of blood units transfused has been reported in France. In contrast, since 2002, there is an increasing number of blood units issuing (+7.6% between 2001 and 2006) and this must be investigated. On behalf of the French Society of Blood Transfusion, the "Recipients" working group promoted a nation wide survey with the support of the regional blood transfusion centres. This survey was aimed at describing the profiles of the transfused patients: socio-demographical patterns, and reasons of the blood transfusion (main and associated diagnoses). A cross-sectional survey was designed. All the patients who received a blood unit during a specific day were considered as the population of the study. They were identified by the regional transfusion centres by means of the "individual issuing form". Survey forms were fully filled for 90% of the patients. It has been considered as a good answer rate. Seven thousand four hundred and twenty-two blood units, delivered to 3450 patients were analyzed. Three groups of pathologies were found as a reason of transfusion: haematology-oncology (52.70% of the prescriptions) with 892 patients (27.8%) for haematological malignancies; surgical procedures (23.99%); intensive care and medicine procedures (21.92%). More than 50% of the recipients are 70 years old and more. This result is explained by the age distribution of inpatients. In a context of lack of donors and consequently difficulties to provide patients with optimal number of blood units, this study is helpful. Variability of blood unit issuings must be detected, analyzed and monitored in real time by the actors of the transfusion process, using computerized dashboards: the blood units provider (in order to adjust the strategy of blood units provision) and the health care establishment as well as care blood components prescribers (reasons of blood transfusion and evaluation of practices).

We explored the possibility of the cryo-storage of cord blood hematopoietic stem cells (CBHPSC) with respect to the quantity, quality and biologic efficacy of high altitude (HA) region Abha against sea level (SL) region. The results of the post-processed total nucleated cell count was 8.03 ± 0.31 × 10 7 and 8.44 ± 0.23 × 10 7 cells in the HA and SL regions respectively. The mean post processing viability of the nucleated cells was about 87.03 ± 1.39 (HA) and 88.33 ± 1.55% (SL) while post thaw cells were 85.61 ± 1.44 (HA) and 86.58 ± 1.61% (SL) after transient cryo-storage. The proliferation of CBHSCs after thawing were comparable between the HA and SL regions. The results of the colony forming unit (CFU) assays of CFU-E, CFU-GEMM, CFU-GM and BFU-E were comparable between HA and SL in both fresh and post thaw, while a declining trend with viability was significant. The differentiation capability of post thaw samples into adipocytes and osteocytes were comparable between HA and SL regions. Overall from the results, it can be evidenced that HA cord blood collection, processing or storage does not hinder the quality or biological efficacy of the CBHPSC.

The Kidd-null phenotype, Jk(a-b-), occurs in individuals who do not express the JK glycoprotein. Jk(a-b-) individuals can make an antibody against the Jk3 antigen, a high-incidence antigen present in more than 99.9% of most populations. This presents many challenges to the blood bank including identification of the antibody, masking of other antibodies, and how to provide transfusion support given the rarity of Jk3-negative blood products. Kidd antibodies may cause acute and delayed hemolytic reactions as well as hemolytic disease of the fetus and newborn (HDFN). In this article, we present a series of four practical cases of pregnant women with the anti-Jk3 alloantibody that demonstrate a range of clinical presentations of Kidd-related HDFN. We retrospectively reviewed the clinical and blood bank records for four patients and their newborns encountered at institutions in Tennessee, Missouri, Hawaii, and Guam with an anti-Jk3 identified during pregnancy. Two cases showed no significant evidence for HDFN, while two cases were of mild-to-moderate severity requiring early delivery due to elevated middle cerebral artery (MCA) flow velocities but requiring only phototherapy for hyperbilirubinemia. No intrauterine or neonatal transfusions were necessary. Anti-Jk3 alloantibody titers ranged from 2 to 128. Clinical manifestations of anti-Jk3 HDFN are generally mild to moderate. Anti-Jk3 titers were not found to correlate directly with HDFN severity. We suggest a titer of 16 to 32 as a cutoff for implementing enhanced monitoring of fetal MCA flow velocities, as such titers may be indicative of elevated HDFN risk. © 2018 AABB.

Los estados con mayor prevalencia se ubican en las regiones del occidente y centro del país, a saber: Portuguesa, Barinas, Lara, Trujillo, Cojedes y Carabobo. Por las dificultades en obtener tasas de incidencia para el Mal de Chagas, resulta adecuado emplear tasas de prevalencia para uso en salud pública, en función de su mayor estabilidad; y en el caso de Venezuela, dada la severidad menor y una sobrevivencia mayor por esta patologia hoy día. La especificidad, como parámetro de las pruebas serológicas, debería considerarse en función de la baja seroprevalencia detectada a nivel nacional.

Despite vast improvements in transfusion services in sub-Saharan Africa over the last decade, there remain serious concerns on the safety and adequacy of the blood supply across the region. This review paper ascertains the role of pathogen reduction technology (PRT) in improving blood safety and supply adequacy in the region. The state of blood safety in sub-Saharan Africa was reviewed. Meetings, seminars and correspondence were undertaken with key clinicians, scientists and professional bodies in the region, including the World Health Organization's Regional Office for Africa, to examine the suitability of PRT for improving the safety of whole blood transfusion, a prevalent transfusion format in the region. Existing literature suggests that combining PRT with current blood safety measures (such as serology) would improve the safety and adequacy of the blood supply for transfusions in sub-Saharan Africa. This was echoed by the findings of the stakeholder meetings. Following a detailed appraisal of two leading PRT systems, the Mirasol ® PRT System and the Cerus S-303 System, we suggest that companies conduct comprehensive toxicological evaluation of the agents used for PRT and publish this in the scientific literature. We also recommend that the safety and efficacy of these technologies should be established in a randomised clinical trial conducted in sub-Saharan Africa.

Severe anemia in children is a major public health problem in sub-Saharan Africa. In this study we describe clinical and operational aspects of blood transfusion in children admitted to Coast Provincial General Hospital, Kenya. This was an observational study where over a 2-year period, demographic and laboratory data were collected on all children for whom the hospital blood bank received a transfusion request. Clinical data were obtained by retrospective review of case notes over the first year. There were 2789 requests for blood for children (median age, 1.8 years; interquartile range [IQR], 0.6-6.6 years); 70% (1950) of the samples were crossmatched with 85% (1663/1950) issued. Ninety percent (1505/1663) were presumed transfused. Median time from laboratory receipt of request to collection of blood was 3.6 hours (IQR, 1.4-12.8 hr). Case notes of 590 children were reviewed and median pretransfusion hemoglobin level was 6.0 g/dL (IQR, 4.2-9.1 g/dL). Ninety-four percent (186) were transfused "appropriately" while 52% (120) were transfused "inappropriately." There was significant disagreement between the clinical and laboratory diagnosis of severe anemia (exact McNemar's test; p blood transfusions but only 41% (106) of these had a positive blood film. In this setting, clinicians often order blood based on the clinical impression of "severe anemia." This has implications for laboratory workload and the blood supply itself. However, the majority of children with severe anemia were appropriately transfused. The use of antimalarials with blood transfusions irrespective of blood film results is common practice. © 2016 The Authors. Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

In India approximately 1 million people get burnt every year and most of them are from the lower or middle income strata. Therefore it is obligatory to find out an economic way of treatment for the affected populace. Since use of human skin allograft is the gold standard for the treatment of burn wound, in-house skin banking for a burn unit hospital is prerequisite to make the treatment procedure affordable. Although, there was one skin bank at India till 2009, but it was difficult for a single bank to cover the entire country's need. Looking at the necessities, National Burns Centre (a tertiary burn care centre) along with Rotary International and Euro Skin Bank collaborated and developed an effective cadaveric skin banking model in Mumbai, Maharashtra in 2009. Initial two to three years were formation phase; by the year 2013 the entire system was organized and started running full fledged. The model has also been replicated in other states of India to accommodate the large burn population of the country. This paper therefore, gives a step by step account of how the bank evolved and its present status. Copyright © 2017. Published by Elsevier Ltd.

Due to a USAID-funded study on blood banks, a national policy was instituted in 1994 that set standards for Philippine blood services, promoted voluntary donation, and led to a ban on commercial blood banks. In this follow-up study, we assess the safety of the supply by determining the residual risk for transfusion-transmitted infections (syphilis, hepatitis B and C, HIV). We also identified unsafe facility practices and generated policy recommendations. A 1992 study found that transfusion-ready blood was not safe using the LQAS method (P > 0.05). We found that the 2012 residual risk became 0 to 0.9 percent attributable to the national policy. We noted poor to fair adherence to this policy. We identified unsafe practices such as use of rapid tests and lack of random blood retesting. Training and use of regional networks may improve safety. Despite improvement in safety, facilities complain of funding and logistical issues regarding compliance with the policy.

A relevant issue in Chagas disease serological diagnosis regards the requirement of using several confirmatory methods to elucidate the status of non-negative results from blood bank screening. The development of a single reliable method may potentially contribute to distinguish true and false positive results. Our aim was to evaluate the performance of the multiplexed flow-cytometry anti-T. cruzi/Leishmania IgG1 serology/(FC-TRIPLEX Chagas/Leish IgG1) with three conventional confirmatory criteria (ELISA-EIA, Immunofluorescence assay-IIF and EIA/IIF consensus criterion) to define the final status of samples with actual/previous non-negative results during anti-T. cruzi ELISA-screening in blood banks. Apart from inconclusive results, the FC-TRIPLEX presented a weak agreement index with EIA, while a strong agreement was observed when either IIF or EIA/IIF consensus criteria were applied. Discriminant analysis and Spearman's correlation further corroborates the agreement scores. ROC curve analysis showed that FC-TRIPLEX performance indexes were higher when IIF and EIA/IIF consensus were used as a confirmatory criterion. Logistic regression analysis further demonstrated that the probability of FC-TRIPLEX to yield positive results was higher for inconclusive results from IIF and EIA/IIF consensus. Machine learning tools illustrated the high level of categorical agreement between FC-TRIPLEX versus IIF or EIA/IIF consensus. Together, these findings demonstrated the usefulness of FC-TRIPLEX as a tool to elucidate the status of non-negative results in blood bank screening of Chagas disease. Copyright © 2018.

Regional cerebral blood flow characteristics of the Sturge-Weber syndrome

1985-01-01

Four patients with the Sturge-Weber syndrome were studied using the non-invasive Xenon-133 inhalation technique. All four patients had decreased regional cerebral blood flow in the area of their lesion, and in two patients who were subsequently tested with 5% carbon dioxide inhalation, impaired vasomotor reactivity was documented. Diminished regional cerebral blood flow is consistent with previously described nuclide flow studies which demonstrated a delay in the initial perfusion blush in the region of the abnormal vasculature. The focal decrease in blood flow was greatest in the most severely affected patient, but was also prominent in the two younger patients, both of whom have excellent neurologic function. These studies suggest that localized decrease in blood flow and vasomotor dysfunction in Sturge-Weber syndrome can precede the occurrence of severe neurologic impairment and extensive cerebral atrophy and possibly be a major contributing factor in progressive dysfunction. A secondary observation was that the blood flow in the unaffected hemisphere was significantly greater in two children compared to the two adults and was similar to the age-related differences reported for normal children and adults

A new technique for estimating regional hepatic blood flow using the inert gas washout technique and scintillation camera following injection of /sup 133/Xe into the spleen is presented. This technique is easily, rapidly and repeatedly performed and permits the measurement of nutrient hepatic tissue blood flow. Measurement of regional hepatic blood flow in right and/or left lobes was performed in 28 patients. In all but one patient the right lobar flow value was equal to or greater than the left one. The right lobar flow was 86.20 +- 12.83 ml/100 gm/min in 3 patients without liver disease, 75.12 +- 14.54 ml/100 gm/min in 12 with chronic hepatitis and 51.24 +- 17.13 ml/100 gm/min in 11 with liver cirrhosis. This result suggests that hepatic tissue blood flow is significantly decreased in patients with liver cirrhosis. Scintillation camera images of initial xenon distribution in combination with monitor of washout curves over the liver also provide more information on the presence of extra- and intrahepatic shunts. Therefore, this technique appears to be clinically useful in evaluation of hemodynamic phenomena associated with liver diseases.

N-isopropyl-p- 123 I-iodoamphetamine (IMP) was used to quantify the regional cerebral blood flow (r-CBF) in 11 diabetic patients (average age; 67.9 years) and 12 non-diabetic subjects (average age; 67.4 years), none of whom had (cerebrovascular disease (CVD) on CT studies. A reference sampling method by continuous arterial blood sampling was used to quantify r-CBF. There were no significant differences in physiological or laboratory data between diabetic and non-diabetic groups except for fasting plasma glucose and HbA 1c levels. The average of r-CBF in each region of cerebrum and cerebellum was significantly lower in diabetic group than that in the control group (p<0.01). These observations show that r-CBF of diabetic patients is reduced, even in the absence of findings of CVD on a CT study. (author)

Seasonal distribution of blood donation hinders efforts to provide a safe and adequate blood supply leading to chronic and persistent shortages. This study examined whether holidays, geographical area and donation type (community versus replacement) has any impact on the fluctuation of donations. The numbers of blood donations from 2007 through 2010 in three Brazilian Retrovirus Epidemiological Donor Study II (REDS-II) participating centers were analyzed according to the week of donation. The weeks were classified as holiday or non-holiday. To compare donations performed during holiday versus non-holiday weeks, tabulations and descriptive statistics for weekly donations by blood center were examined and time series analysis was conducted. The average weekly number of donations varied according to the blood center and type of week. The average number of donations decreased significantly during Carnival and Christmas and increased during the Brazilian National Donor Week. The fluctuation was more pronounced in Recife and Belo Horizonte when compared to São Paulo and higher among community donors. National bank holidays affect the blood supply by reducing available blood donations. Blood banks should take into account these oscillations in order to plan local campaigns, aiming at maintaining the blood supply at acceptable levels.

How safe is the blood supply?

Science.gov (United States)

Many poor people in Indian cities sell their blood to commercial blood banks for up to US$2.50. In fact, so many have done so that there once was a Professional Blood Donors Association. It dissolved though after some members died of AIDS. Health workers believe at least 25% of blood donors in Bombay are HIV positive. Yet a recent study of 70 professional blood donors in Bombay shows only 7 who did not test positive for HIV. Still the government of India does not require blood banks to test for HIV, hepatitis, or other blood borne diseases. In fact, the blood supply is monitored in only 5 cities in India. In India as well as in other Asian countries, physicians advise patients to donate their own blood and have it stored until needed for surgery or to ask for safer blood substitutes, e.g., plasma expanders. In fact, in Singapore, the Autologous Blood Bank charges US$21/year to store units of blood for future use. In Japan, most of the 2008 HIV infected people had received blood plasma from mainly the US before Japan required new sterilization regulations on blood imports. The greatest risk from blood donors comes from those who are paid for their blood because they tend to be poor, to practice unsafe sex, and not to be mindful of their health. Most Asian nations such as Japan and Singapore do screen the blood supply. Further, for almost 20 years, Thailand has checked its blood supply for hepatitis B and syphilis. In 1987, it began testing for AIDS. It does not pay for donated blood. In the Philippines, however, even paying blood donors does not meet the needed blood supply and much of the blood comes from commercial blood banks. Yet the Philippine Red Cross has screened for other diseases since 1960 and for AIDS since 1988.

Comeal transplantation is the only method of combating the blindness due to corneal opacity caused by infections, malnutrition, trauma and hereditary diseases. Comeal blindness is more prevalent in the developing countries. The availability of the donor cornea, trained ophthalmic surgeons and microsurgery facilities are the key factors in restoring vision in-patients with comeal blindness. The eye bank organization is somewhat similar to that of blood bank. The eye bank should be located in a hospital or a medical centre in which a laboratory may be established for the evaluation and storage of donor tissue. The medical director (Ophthalmologist), technician, secretary and public relation officer are the persons who play an important role in the successful organization of eye bank. The function of the eye bank are procurement, assessment, processing, distribution of donor eyes/corneas, training of technicians/doctors, and conducting research related to storage of donor tissue and corneal transplantation. The necessary infrastructure required for the organization of an eye bank include separate accommodation area for the personnel and the laboratory, telephone, computer, refrigerator, laminar air flow hood. Slitlamp, specular microscope, storage media and equipment, instrument for enucleation of donor eyes, and a motor vehicle. The details of responsibilities of the staff of eye bank, source of donor eyes, suitability of donor material, procurement of the donor cornea, tissue assessment, storage and preservation, distribution of donor tissue, and limitation of eye bank will be discussed at the time of presentation

Dorso-caudal areas of dog lungs are better perfused than ventral regions, independent of gravity. Could this be an artifact due to regional bias in lodging of MS. The costal surfaces of 5 isolated blood perfused left lungs of dogs [constant blood flow (F), Ppa, Ppv and Palv] were imaged (gamma camera) first after injection of 141 Ce-labeled MS (15 μ), then in 0.4 sec intervals after a bolus injection of 99 Tc-labeled red blood cells (RBC). Count rates were analyzed in 6 regions. Regional flow measured by MS (flowMS) is F times regional counts divided by total counts in the first image. Regional flow measured by RBC (flowRBC) is F times peak regional counts divided by peak total counts in the 0.4 sec images. The ratio flowMS/flow RBC was greater than 1.0 (P<0.001), suggesting a systematic difference between 1.0 (P<0.001), suggesting a systematic difference between flowMS and flow RBC. More importantly, there was no difference in flowMS/flow RBC among lung regions, allowing the authors to conclude there was no regional bias of flows

This study aimed to verify the performance of blood transfusion committees in transfusion services linked to the public blood bank network of the state of Minas Gerais. A cross-sectional observational study was conducted between 2007 and 2008 using questionnaires and proficiency tests to evaluate the reporting and investigation of transfusion reactions comparing transfusion services with and without transfusion committees in the public transfusion services of the state of Minas Gerais. Nineteen of Hemominas own transfusion services and 207 that contracted the services of the foundation located in 178 municipalities were visited between 2007 and 2008. Established transfusion committees were present in 63.4% of the services visited. Transfusion incidents were reported by 53 (36.8%) transfusion services with transfusion committees and by eight (9.6%) without transfusion committees (p < 0.001) with 543 (97.5%) and 14 (2.5%) notifications, respectively. Of the reported transfusion incidents, 40 (75.5%) transfusion services with transfusion committees and only two (25%) of those without transfusion committees investigated the causes. The incidence of notification and investigation of the causes of transfusion reactions was higher in transfusion services where a transfusion committee was present. Despite these results, the performance of these committees was found to be incipient and a better organization and more effective operation are required.

Discipline as a means of production: A study based on a disciplinary system in a French regional bank

Directory of Open Access Journals (Sweden)

Lioner Honore

2004-01-01

Full Text Available The purpose of this paper is to investigate the way in which banks take into account the transformation of both the substance of their activity and the framework governing it. This relates to the way they do (or do not transform the organization of the production process when its substance significantly changes, as well as to the key factors governing their commercial and financial success. The underlying idea is that, for some banks, taking these mutations into account has resulted in changing the way they operate on the basis of “economics of discipline”. The first part of this article presents the main elements of the theory of organizational discipline. The aim is to present the conceptual tools used to analyze the disciplinary system of a bank. The second part of the article gives an example of a disciplinary system based on the study of a French regional bank.

Measurement of regional pulmonary blood volume in patients with increased pulmonary blood flow or pulmonary arterial hypertension

Wollmer, P.; Rozcovek, A.; Rhodes, C.G.; Allan, R.M.; Maseri, A.

1984-01-01

The effects of chronic increase in pulmonary blood flow and chronic pulmonary hypertension on regional pulmonary blood volume was measured in two groups of patients. One group of patients had intracardiac, left-to-right shunts without appreciable pulmonary hypertension, and the other consisted of patients with Eisenmenger's syndrome or primary pulmonary hypertension, i.e. patients with normal or reduced blood flow and severe pulmonary hypertension. A technique based on positron tomography was used to measure lung density (by transmission scanning) and regional pulmonary blood volume (after inhalation of /sup 11/CO). The distribution of pulmonary blood volume was more uniform in patients with chronic increase in pulmonary blood flow than in normal subjects. There were also indications of an absolute increase in intrapulmonary blood volume by about 15%. In patients with chronic pulmonary arterial hypertension, the distribution of pulmonary blood volume was also abnormally uniform. There was, however, no indication that overall intrapulmonary blood volume was substantially different from normal subjects. The abnormally uniform distribution of pulmonary blood volume can be explained by recruitment and/or dilatation of vascular beds. Intrapulmonary blood volume appears to be increased in patients with intracardiac, left-to-right shunts. With the development of pulmonary hypertension, intrapulmonary blood volume falls, which may be explained by reactive changes in the vasculature and/or obliteration of capillaries

The World Health Organization (WHO) recommends the creation of national blood transfusion services. Burkina Faso has a CNTS (Centre National de Transfusion Sanguine-National Blood Transfusion Center) but it currently covers only 53% of the national blood supply versus 47% produced by independent hospital blood banks. To evaluate blood collection, testing, preparation, and prescription practices in the regions of Burkina Faso that are not covered by the CNTS, a cross-sectional survey was conducted. Data were collected by trained professionals from May to June 2009 at 42 autonomous blood centers not covered by the CNTS. Blood collection was supervised in all sites by laboratory technicians without specific training. There was no marketing of community blood donation nor mobile collection. Donation was restricted to replacement (family) donors in 21.4% of sites. Predonation screening of donors was performed in 63.4% of sites, but some did not use written questionnaires. Testing for HIV, hepatitis B virus, and syphilis was universal, although some sites did not screen for hepatitis C virus. In 83.3% of the sites, blood typing was performed without reverse ABO typing. In 97.6% of the sites, nurses acted alone or in conjunction with a physician to order blood transfusions. Shortcomings in non-CNTS blood centers argue for the development of a truly national CNTS. Such a national center should coordinate and supervise all blood transfusion activities, and is the essential first step for improving and institutionalizing blood transfusion safety and efficacy in a developing country. © 2011 American Association of Blood Banks.

Factors affecting regional pulmonary blood flow in chronic ischemic heart disease

International Nuclear Information System (INIS)

Pistolesi, M.; Miniati, M.; Bonsignore, M.

1988-01-01

To assess the effect of left heart disease on pulmonary blood flow distribution, we measured mean pulmonary arterial and wedge pressures, cardiac output, pulmonary vascular resistance, pulmonary blood volume, and arterial oxygen tension before and after treatment in 13 patients with longstanding ischemic heart failure and pulmonary edema. Pulmonary edema was evaluated by a radiographic score, and regional lung perfusion was quantified on a lung scan by the upper to lower third ratio (U:L ratio) of pulmonary blood flow per unit of lung volume. In all cases, redistribution of lung perfusion toward the apical regions was observed; this pattern was not affected by treatment. After treatment, pulmonary vascular pressures, resistance, and edema were reduced, while pulmonary blood volume did not change. At this time, pulmonary vascular resistance showed a positive correlation with the U:L ratio (r = 0.78; P less than 0.01), whereas no correlation was observed between U:L ratio and wedge pressure, pulmonary edema, or arterial oxygen tension. Hence, redistribution of pulmonary blood flow, in these patients, reflects chronic structural vascular changes prevailing in the dependent lung regions

Regional blood flow in experimental myositis ossificans

1983-01-01

In a recent model for heterotopic bone formation, muscular oedema, swelling and necrosis is seen in the quadriceps muscle of rabbit hind limbs immobilized for at least 2 weeks when, from the second week, the immobilized limb is subjected to dayly forcible mobilization lasting about 5 min. According to this model, heterotopic calcification develops gradually from the second week of forcible mobilization and is located in the vastus intermedius region. Between the fourth and fifth week of immobilization and forcible mobilization, heterotopic bone formation is seen in virtually all cases. The histological findings are similar to those in human ectopic bone formation. In the present investigation the labelled microsphere technique was used to study the regional blood flow effects in the early development of myositis ossificans with this model. The results are quite different from those reported by other investigators on immobilization alone and point to a causal relation between regional blood flow and forcible mobilization of the immobilized rabbit hind limp. Prostaglandins as mediators between the traumatic inflammation, a part of the circulatory effects observed and the induction of a new bone is suggested. (author)

Human milk banking.

2013-01-01

Forms of human milk banking and donation have been present for more than a century worldwide, but, since 1985, the Human Milk Banking Association of North America (HM BANA) has established guidelines to make the use of donor's breast milk safe and the second best form of feeding to maternal breast milk for a neonatal intensive care unit (NICU) infant. The Indiana Mother's Human Milk Bank provides an extensive and meticulous process of selecting breast milk donors. The process begins with a phone interview with a potential donor and includes the review of the donor's medical records, blood laboratory screening, medication and dietary intake, as well as consent from the donor's pediatrician. The milk bank follows steps of collecting, storing, and receiving the breast milk in accordance with the guidelines of the HM BANA. Pasteurization is the method used to ensure the proper heating and cooling of breast milk. Despite the rigorous pasteurization method, the donor's breast milk will not lose most of the important beneficial components needed for sick or ill NICU infants. Every batch of pasteurized breast milk will be cultured for any possible contamination and shipped to NICUs after it has been cleared by laboratory testing.

Characterization of the ABO blood group at the phenotype and genotype levels is clinically essential for transfusion, forensics, and population studies. This study elucidated ABO phenotypes and genotypes, and performed an evaluation of their distribution in individuals from the western region of Saudi Arabia. One-hundred and seven samples underwent standard serological techniques for ABO blood group phenotype analysis. ABO alleles and genotypes were identified using multiplex polymerase chain reaction, and electrophoretic analysis was performed to evaluate the highly polymorphic ABO locus. A phenotype distribution of 37.4%, 30.8%, 24.3%, and 7.5% was found for blood groups O, A, B, and AB respectively in our study cohort. Genotype analysis identified 10 genotype combinations with the O01/O02 and A102/O02 genotypes being the most frequent with frequencies of 33.6% and 14.95%, respectively. Common genotypes such as A101/A101 , A101/A102 , A101/B101 , B101/B101 , and O01/O01 were not detected. Similarly, the rare genotypes, cis-AB01/O02 , cis-AB01/O01 , and cis-AB01/A102 were not found in our cohort. The most frequently observed allele was O02 (35.98%) followed by the A102 allele (17.76%). Furthermore, our findings are discussed in reference to ABO allele and genotype frequencies found in other ethnic groups. The study has a significant implication on the management of blood bank and transfusion services in Saudi Arabian patients.

Full Text Available The aim of this study is to measure the customer satisfaction and to identify the shortfall areas for improving the services of public banking sector. For this research paper past research survey were studied. The main concept is measuring customer satisfaction by customer satisfaction index method. All the factors related to banks were taken by personal interview with the banks’ manager which influences customer satisfaction. To collect the information non-probability sampling method is used. 100 services users of two different banks in bardoli region were contacted with face-to-face personal interview method through questionnaire. “Customer Satisfaction Index” method was used to measure the customer satisfaction. The study represents the result of a survey among the customers in the bardoli region of two public sector banks. Study proved that the STATE BANKS OF INDIA’S customers are more satisfied (82.55> 81.79 than BANK OF INDIA’S customers. There were parameters are found out which are more important to increasing the satisfaction rate. The results of this study provide very important information in formulating competitive marketing strategies. It shows the critical points where the limited resources of the banks should be allocated to improve satisfaction and loyalty and provides information about the weaknesses and strengths of the banks from the eyes of its customers. With getting the valuable information and found out the reason of dissatisfaction these banks can put more efforts to improving the standards of services and make the customers more satisfied.

Puumala hantavirus infections in bank vole populations: host and virus dynamics in Central Europe.

In Europe, bank voles (Myodes glareolus) are widely distributed and can transmit Puumala virus (PUUV) to humans, which causes a mild to moderate form of haemorrhagic fever with renal syndrome, called nephropathia epidemica. Uncovering the link between host and virus dynamics can help to prevent human PUUV infections in the future. Bank voles were live trapped three times a year in 2010-2013 in three woodland plots in each of four regions in Germany. Bank vole population density was estimated and blood samples collected to detect PUUV specific antibodies. We demonstrated that fluctuation of PUUV seroprevalence is dependent not only on multi-annual but also on seasonal dynamics of rodent host abundance. Moreover, PUUV infection might affect host fitness, because seropositive individuals survived better from spring to summer than uninfected bank voles. Individual space use was independent of PUUV infections. Our study provides robust estimations of relevant patterns and processes of the dynamics of PUUV and its rodent host in Central Europe, which are highly important for the future development of predictive models for human hantavirus infection risk.

Regional cerebral blood flow in the patient with brain tumor

1993-01-01

Regional cerebral blood flow (rCBF) was measured with xenon-enhanced CT (Xe-CT) in 21 cases of intracranial tumors (13 meningiomas, 5 gliomas, 3 metastatic brain tumors). Peritumoral edema was graded as mild, moderate or severe based on the extent of edema on CT and MRI. According to intratumoral blood flow distribution patterns, three patterns were classified as central type with relatively high blood flow at the center of the tumor, homogeneous type with an almost homogeneous blood flow distribution, and marginal type with relatively high blood flow at the periphery of the tumor. High grade astrocytoma and metastatic brain tumor showed marginal type blood flow and moderate or severe edema except in one case. Five meningiomas with severe peritumoral edema revealed marginal type blood flow and four with mild peritumoral edema showed central type blood flow, except for one case. No correlation was found between the extent of peritumoral edema and histological subtype, tumor size, location, duration of clinical history, vascularization on angiogram, and mean blood flow in the tumor. These results suggest that blood flow distribution patterns within the tumor may affect the extension of peritumoral edema. Pre- and postoperative rCBFs were evaluated with Xe-CT and IMP-SPECT in 7 cases, mean rCBF of peritumoral edema was 6.2 ml/100 g/min preoperatively, and discrepancy between rCBF on Xe-CT and that on IMP-SPECT was shown in the remote cortical region ipsilateral to the tumor. Postoperative rCBF revealed an improved blood flow in both adjacent and remote areas, suggesting that the decreased blood flow associated with brain tumors might be relieved after surgery.

Can a decentralized blood system ensure self-sufficiency and blood safety? The Lebanese experience.

Science.gov (United States)

Haddad, Antoine; Bou Assi, Tarek; Garraud, Olivier

2017-08-01

Lebanon has adopted a liberal economic system that also applies to healthcare procurement. There is no national Lebanese blood transfusion service and the blood supply is divided between a large number of licensed (45 per cent) and unlicensed (55 per cent) blood banks, many of them issuing a very limited number of blood components. All blood banks are hospital based and operate the entire transfusion chain, from collection to the release of blood units. Blood donation is voluntary and non-remunerated in 20-25 per cent of donations; it relies principally on replacement donations. Recently, Lebanon has faced political instability and war, and now welcomes an enormous number of refugees from neighboring countries at war. This has had an important impact on heath care and on the transfusion supply. We discuss the impact of the blood donation organization on the transfusion safety and ethics, to set the foundation for a more developed and safer transfusion programs.

Studies on age-related changes, regional and bilateral differences in the skin blood flow

Park, Myung-Wook

1992-01-01

Xenon-133 clearance method was used to determine skin blood flow at different sites. The correlation between skin blood flow in the deltoid region and age was examined. In addition, regional and bilateral differences in skin blood flow were examined. The subjects were 60 men. They ranged in age from 23 to 72 years with a mean of 53.3±10.95. Fifty μCi of xenon-133 dissolved in 0.1 ml of sterile distilled water was injected into the skin area. The clearance curve over the skin was recorded for 30 minutes by a scintillation counter. Skin blood flow in the deltoid region decreased significantly with aging. Dorsal skin blood flow in the hands and feet were significantly lower than the deltoid region. Regarding skin blood flow in the deltoid regions, there was significantly bilateral difference. In the hands and feet, the dorsal skin was bilaterally nearly equal. In view of regional hemodynamics in the skin, the conditions for random-pattern skin flap and wound healing were unfavorable in the elderly as compared with younger persons. Skin blood flow decreased gradually from the upper part of the body to the lower part of the body. In skin blood flow in the dorsal skin of the hands and feet, no bilateral difference was observed.

The anatomy of bank performance during transition: A separate efficient frontier analysis of Ukrainian banks

Directory of Open Access Journals (Sweden)

Ihsan Isik

2016-04-01

Full Text Available By drawing on Ukrainian experience, this paper analyzes the anatomy of bank efficiency in a transitional economy. Acknowledging the vast disparities in the business technology of different size banks, in this comprehensive study, we innovatively estimate group-specific (distinct frontiers for small, medium, and large size banks. The results from separate frontiers reveal that Ukrainian banks record 38% technical inefficiency, 26% pure technical inefficiency, and 17% scale inefficiency on average. Apparently, banks in transition waste about the two fifths of their factor inputs during the production of financial services. The cardinal source of sub-performance in transitional banks seems to be managerial inefficiencies. We also found that banks operating in areas with more political influence and more developed infrastructure outperform the banks operating in politically and economically weaker regions. The results also indicate that larger banks, enjoying public trust in a risky business climate, dominate smaller banks in all forms of efficiency. However, such bias for size causes large banks to suffer from decreasing returns to scale and small banks from idle capacity. Consequently, the policies promoting consolidation between small and large banks may alleviate the excess (idle capacity for large (small banks in a transitional economy.

Graphite furnace atomic absorption spectrometry, with Zeeman background correction and after improved matrix modification, was used to measure the plasma selenium content of healthy blood bank donors in the central part of Belgium. The mean plasma selenium concentration of 80 men and 80 women was 79.7+/-4.4ng/mL with a range of 55.0-117.4ng/mL. There was no gender difference observed. Plasma selenium level was significantly highest for the adult group, aged 45-64 years, compared to the others, except the young adults (18-24 years). The mean plasma selenium concentration measured corresponded well with literature data for Belgium. The obtained values were found to be in the medium range, compared with recent literature values for the European countries.

Previous studies found changes in regional cerebral blood flow (rCBF) patterns related to both age and various cognitive tasks. However, no study has yet demonstrated a relationship between rCBF and performance on the Luria-Nebraska Neuropsychological Battery (LNNB) in an elderly group. Seventy-nine elderly volunteers (56-88 years old), both healthy and demented, underwent the 133 xenon inhalation rCBF procedure and were given the LNNB. The decrements in the gray-matter blood flow paralleled decrements in performance on the LNNB. Using partial correlations, a significant proportion of shared variance was observed between gray-matter blood flow and the LNNB scales. However, there was much less of a relationship between white-matter blood flow and performance on the LNNB. This study suggests that even within a restricted age sample rCBF is related in a global way to neuropsychological functioning

Hospital transfusion laboratories collect information regarding blood transfusion and some registries gather clinical outcomes data without transfusion information, providing an opportunity to integrate these two sources to explore effects of transfusion on clinical outcomes. However, the use of laboratory information system (LIS) data for this purpose has not been validated previously. Validation of LIS data against individual patient records was undertaken at two major centers. Data regarding all transfusion episodes were analyzed over seven 24-hour periods. Data regarding 596 units were captured including 399 red blood cell (RBC), 95 platelet (PLT), 72 plasma, and 30 cryoprecipitate units. They were issued to: inpatient 221 (37.1%), intensive care 109 (18.3%), outpatient 95 (15.9%), operating theater 45 (7.6%), emergency department 27 (4.5%), and unrecorded 99 (16.6%). All products recorded by LIS as issued were documented as transfused to intended patients. Median time from issue to transfusion initiation could be calculated for 535 (89.8%) components: RBCs 16 minutes (95% confidence interval [CI], 15-18 min; interquartile range [IQR], 7-30 min), PLTs 20 minutes (95% CI, 15-22 min; IQR, 10-37 min), fresh-frozen plasma 33 minutes (95% CI, 14-83 min; IQR, 11-134 min), and cryoprecipitate 3 minutes (95% CI, -10 to 42 min; IQR, -15 to 116 min). Across a range of blood component types and destinations comparison of LIS data with clinical records demonstrated concordance. The difference between LIS timing data and patient clinical records reflects expected time to transport, check, and prepare transfusion but does not affect the validity of linkage for most research purposes. Linkage of clinical registries with LIS data can therefore provide robust information regarding individual patient transfusion. This enables analysis of joint data sets to determine the impact of transfusion on clinical outcomes. © 2010 American Association of Blood Banks.

Cord blood (CB) is considered an alternative resource to bone marrow and peripheral blood stem cells (PBSC) for allogeneic stem cell transplantation. In this study, human leukocyte antigen (HLA)-A, -B, and -DRB1 high-resolution allele types were analyzed from a total of 710 CB units in the Tzu Chi Taiwan Cord Blood Bank. We observed 21 HLA-A alleles, 59 HLA-B alleles, and 28 HLA-DRB1 alleles, whereas 19 unique alleles were present in the CB units of 2,023 individuals selected for confirmatory testing in the Tzu Chi Taiwan Marrow Donor Registry (TCTMDR). The allelic associations between the HLA-A and -B locus were stronger than that of either the HLA-B and -DRB1 loci or the HLA-A and -DRB1 loci. The most common haplotype of CB units in the general Taiwanese population was A*3303-B*5801-DRB1*0301 (6.59%), followed by A*0207-B*4601-DRB1*0901 (3.47%) and then A*1101-B*4001-DRB1*0901 (2.11%). Moreover, two haplotypes, A*2402-B*5201-DRB1*1502 and A*0201-B*1301-DRB1*1202, existed uniquely in the CB units but were not observed in the data of TCTMDR. Although the number of CB units studied for high-resolution of HLA typing in the current study is small, we believe our data should provide useful information to increase the chances of obtaining acceptable HLA-A-, -B-, and -DRB1-matched CB units for patients.

Full Text Available Abstract Background: Today, the role of word of mouth (WOM in making decision particularly in service sector became important. Thus, this study aimed to investigate the effect of word of mouth on pregnant woman decision-making behavior to join the Royan Cord Blood Bank. Materials and Methods: The research is operational and has a causal nature. The population of study was 790 pregnant women enrolled in Royan Cord Blood Bank in Arak city that 294 subjects were selected by available non-random sampling method. To collect data, questionnaire instrument was used. Data were analyzed according to Structural Equations Modeling (SEM by LISREL (version 8.54 software. Results: The results of the study revealed that the effect of communication medium on personal information source and word of mouth was significant and positive. In addition, opinion leaders had a significant and positive influence on personal information source and word of mouth and also, the significant and negative effect of opinion leaders on perceived risk was seen. Personal information source had a significant and positive effect on decision-making. However, social structure didn't have any effect on word of mouth. Likewise, word of mouth didn't influence decision-making. Conclusion: According to the findings of the research, it seems that paying attention to the prerequisites and conditions making a suitable bed for creating effective word of mouth and expanding it to making decision for joining the Royan Cord Blood Bank is very necessary.

Blood donation on posters: a worldwide review.

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

Transfusion-transmitted malaria is a severe disease with high fatality rate. Most Brazilian blood banks in the Amazon region perform malaria screening using microscopic examination (thick smears). Since low parasite concentrations are expected in asymptomatic blood donors a high sensitivity test should be used for donor screening. This study determined the sensitivity of a nested-PCR for plasmodium detection in pooled samples. We performed a one-stage criterion validation study with 21 positive samples pooled with samples from ten negative volunteer until three different concentrations were reached (0.33; 0.25; 0.20 parasites/μL - p/μL). Nested PCR was performed as described by Snounou et al. (1993). Sensitivities (and confidence intervals) were determined by stratum of final parasite concentration on the pooled samples. All samples with parasitemia values of 0.33 and 0.25 p/μL had 100% sensitivity (95%CI=86.3-100). One negative result was obtained from a sample with 0.20 p/μL sensitivity=95.2% (95%CI=76.2-99.9). Compared to parasitemia detectable under ideal conditions of thick smear, this nested-PCR in pooled sample was able to detect 40 times more parasites per microliter. Nested-PCR in pooled samples should be considered as a high sensitive alternative to thick smear for donor screening in blood banks at endemic regions. Local authorities need to assess cost:benefit advantages of this method compared to alternatives. Copyright © 2014 Elsevier Ltd. All rights reserved.

Regional brain glucose metabolism and blood flow in streptozocin-induced diabetic rats

Jakobsen, J.; Nedergaard, M.; Aarslew-Jensen, M.; Diemer, N.H.

1990-01-01

Brain regional glucose metabolism and regional blood flow were measured from autoradiographs by the uptake of [ 3 H]-2-deoxy-D-glucose and [ 14 C]iodoantipyrine in streptozocin-induced diabetic (STZ-D) rats. After 2 days of diabetes, glucose metabolism in the neocortex, basal ganglia, and white matter increased by 34, 37, and 8%, respectively, whereas blood flow was unchanged. After 4 mo, glucose metabolism in the same three regions was decreased by 32, 43, and 60%. This reduction was paralleled by a statistically nonsignificant reduction in blood flow in neocortex and basal ganglia. It is suggested that the decrease of brain glucose metabolism in STZ-D reflects increased ketone body oxidation and reduction of electrochemical work

Community in Credit Unions: Has banking regulationimpaired CSR in Australian Customer Owned Banks?

Directory of Open Access Journals (Sweden)

Dianne McGrath

2017-02-01

Full Text Available This paper presents a sector scan of a sample of Australian Credit Unions and Mutual Banks to examine the CSR reporting from the perspective of the three pillars model proposed by vanOorschot, de Hoog, van der Steen and van Twist (2013. It is argued that the pillar requiringco-operatives to ensure activities which ‘aim for change’, should promote increasing adoptionof CSR. The paper theorises that regulatory requirements imposed in Australia on all bankinginstitutions carry a higher proportional cost to the customer owned banking sector than theshareholder based commercial banks. This consumption of the limited financial resourcesavailable in this sector of banking services, are inhibiting regional Customer Owned Bankingproviders, as co-operative organisations, to fulfil the required co-operative principle to instigatechange for the betterment of communities. This failure could signal the demise of some entitiesin the jurisdiction of Customer Owned Banking.

ORIGINAL ARTICLE: Blood Donor’s Status of HIV, HBV, HCV and Syphilis in this Region of Marathwada, India

Full Text Available Aims & Objectives: Blood transfusion can cause the transmission of infections to recipients. This is an important mode of infection. The aim of study was to assess the prevalence of such type of infections among blood donors and to compare the seroprevalence of transfusion transmitted diseases in voluntary donors and replacement donors. Retrospective study of five years from Jan. 2007 to Dec. 2011 was done. This study was conducted at Blood bank, MIMSR Medical College Latur, Govt. Medical College, Latur and Bhalchandra Blood bank, Latur. Material & Methods: Total 10, 4925 donors were tested. Donors were screened for seroprevalence of HIV, HBC, HCV and Syphilis. Screening of HIV, HBV & HCV was done by ELISA method & Syphilis was screened by RPR type. Results: The comparison of seroprevalence of HIV, HBV, HCV & Syphilis in voluntary donors and replacement donors showed significant difference only for HIV in the years 2007, 2010, and 2011. Conclusion: The seroprevalence of transfusion transmitted diseases in the study is very low or negligible in voluntary donors as compared to replacement donors. There was a declining trend of seroprevalence for all the disease screened. But in our study the difference is not significant, which indicates that the selection of donors is of low quality. The selection of high quality voluntary donors should be achieved by creation of awareness by education of the prospective donor populations.

The remaining 48,7 % determined by other factors that are not revealed in this study, for example: job resources and job demands. Keywords: Psychological capital, work engagement, employee

Rapid transport of CCL11 across the blood-brain barrier: regional variation and importance of blood cells.

Science.gov (United States)

Erickson, Michelle A; Morofuji, Yoichi; Owen, Joshua B; Banks, William A

2014-06-01

Increased blood levels of the eotaxin chemokine C-C motif ligand 11 (CCL11) in aging were recently shown to negatively regulate adult hippocampal neurogenesis. How circulating CCL11 could affect the central nervous system (CNS) is not clear, but one possibility is that it can cross the blood-brain barrier (BBB). Here, we show that CCL11 undergoes bidirectional transport across the BBB. Transport of CCL11 from blood into whole brain (influx) showed biphasic kinetics, with a slow phase preceding a rapid phase of uptake. We found that the slow phase was explained by binding of CCL11 to cellular components in blood, whereas the rapid uptake phase was mediated by direct interactions with the BBB. CCL11, even at high doses, did not cause BBB disruption. All brain regions except striatum showed a delayed rapid-uptake phase. Striatum had only an early rapid-uptake phase, which was the fastest of any brain region. We also observed a slow but saturable transport system for CCL11 from brain to blood. C-C motif ligand 3 (CCR3), an important receptor for CCL11, did not facilitate CCL11 transport across the BBB, although high concentrations of a CCR3 inhibitor increased brain uptake without causing BBB disruption. Our results indicate that CCL11 in the circulation can access many regions of the brain outside of the neurogenic niche via transport across the BBB. This suggests that blood-borne CCL11 may have important physiologic functions in the CNS and implicates the BBB as an important regulator of physiologic versus pathologic effects of this chemokine.

In Germany, human tissue for corneal and amniotic transplantation is supplied by 27 cornea banks. The Section for Tissue Transplantation and Biotechnology of the German Ophthalmological Society records the cornea banks' activities by means of an annual questionnaire. In 2009, a total of 4,818 corneal grafts were processed by 21 responding cornea banks, and 57% were deemed suitable for transplantation. This ratio is slightly higher than the European average. In addition, German cornea banks released 1,257 amniotic grafts in 2009. German cornea banks are currently facing new regulatory issues due to updated legislation regarding tissue transplantation. Recent updates in European law have limited the cutoff time for postmortem blood sampling to 24 h, and this regulation may lead to a significant reduction in potential donors.

Invited review: climate change impacts in polar regions: lessons from Antarctic moss bank archives.

Science.gov (United States)

Royles, Jessica; Griffiths, Howard

2015-03-01

Mosses are the dominant plants in polar and boreal regions, areas which are experiencing rapid impacts of regional warming. Long-term monitoring programmes provide some records of the rate of recent climate change, but moss peat banks contain an unrivalled temporal record of past climate change on terrestrial plant Antarctic systems. We summarise the current understanding of climatic proxies and determinants of moss growth for contrasting continental and maritime Antarctic regions, as informed by 13C and 18O signals in organic material. Rates of moss accumulation are more than three times higher in the maritime Antarctic than continental Antarctica with growing season length being a critical determinant of growth rate, and high carbon isotope discrimination values reflecting optimal hydration conditions. Correlation plots of 13C and 18O values show that species (Chorisodontium aciphyllum / Polytrichum strictum) and growth form (hummock / bank) are the major determinants of measured isotope ratios. The interplay between moss growth form, photosynthetic physiology, water status and isotope composition are compared with developments of secondary proxies, such as chlorophyll fluorescence. These approaches provide a framework to consider the potential impact of climate change on terrestrial Antarctic habitats as well as having implications for future studies of temperate, boreal and Arctic peatlands. There are many urgent ecological and environmental problems in the Arctic related to mosses in a changing climate, but the geographical ranges of species and life-forms are difficult to track individually. Our goal was to translate what we have learned from the more simple systems in Antarctica, for application to Arctic habitats. © 2014 John Wiley & Sons Ltd.

Full Text Available The threat of hepatitis E is being felt in blood banks in recent times. The disease is usually self-limiting, but may progress to a fulminant fatal form. We report a unique case of a hepatitis E virus (HEV-positive asymptomatic blood donor who later developed jaundice and informed the blood bank. A blood donor passed all eligibility criteria tests and donated blood. After 20 days, the blood bank was informed by the donor that he had developed vomiting and jaundice 1 day postdonation. He was investigated by a local laboratory 1 day postdonation for liver profile, which was high. There had been a major outbreak in his community of similar symptoms during the same period. HEV IgM antibody by enzyme-linked immunosorbent assay was positive. Silent infections may be lurking in apparently healthy donors. Donors need to be encouraged to revert in case of any significant developments after donation and maintain open channels of communication.

Regional cerebral blood flow in childhood headache

International Nuclear Information System (INIS)

Roach, E.S.; Stump, D.A.

1989-01-01

Regional cerebral blood flow (rCBF) was measured in 16 cranial regions in 23 children and adolescents with frequent headaches using the non-invasive Xenon-133 inhalation technique. Blood flow response to 5% carbon dioxide (CO2) was also determined in 21 patients, while response to 50% oxygen was measured in the two patients with hemoglobinopathy. Included were 10 patients with a clinical diagnosis of migraine, 4 with musculoskeletal headaches, and 3 with features of both types. Also studied were 2 patients with primary thrombocythemia, 2 patients with hemoglobinopathy and headaches, 1 patient with polycythemia, and 1 with headaches following trauma. With two exceptions, rCBF determinations were done during an asymptomatic period. Baseline rCBF values tended to be higher in these young patients than in young adults done in our laboratory. Localized reduction in the expected blood flow surge after CO2 inhalation, most often noted posteriorly, was seen in 8 of the 13 vascular headaches, but in none of the musculoskeletal headache group. Both patients with primary thrombocythemia had normal baseline flow values and altered responsiveness to CO2 similar to that seen in migraineurs; thus, the frequently reported headache and transient neurologic signs with primary thrombocythemia are probably not due to microvascular obstruction as previously suggested. These data support the concept of pediatric migraine as a disorder of vasomotor function and also add to our knowledge of normal rCBF values in younger patients. Demonstration of altered vasomotor reactivity to CO2 could prove helpful in children whose headache is atypical

The interface between preparation and use of blood impacts directly on the outcome of hemotherapy. The present study explores the knowledge and opinions of key players at, practical realities at, and quality improvement strategies of this interface. We surveyed clinicians (n = 81) and blood bank staff (n = 25) to assess their knowledge on key issues in their counterparts' working domains, the turnaround time on effecting a blood order from a hospital transfusion laboratory and strategies to improve communication of blood needs to blood banks. Out of 81 clinicians, 20 knew the four available blood products while only 17 knew the three uses of these products. Twenty-three blood bank staff reported the patient's condition as the main factor on which blood orders are based. Forty-four (54.3%) clinicians reported reception of a blood product within an hour of placing the order. Addressing infrastructure and human resource were some of the strategies suggested to improve this step of the transfusion chain. The knowledge of staff at the extreme ends of the clinical interface in their counterparts' working domain is far from adequate. However, they have well formed opinions on strategies to improve this interface.

There is an increasing need for the establishment of a cervical cancer bio-bank that will facilitate both clinical and basic research. The cervical cancer bio-bank was first established in January 1999 and included two stages. First, a GWAS-based sample collection was conducted with special emphasis on the diagnosis and the retrieval of the corresponding bio-specimens, especially blood samples. Second, clinical data and their corresponding bio-specimens were routinely collected and handled. Notably, these bio-specimens also included samples from Wufeng Tujia Autonomous County, which has the highest incidence of cervical cancer in China. The specimens were collected from patients with cervical cancer and those with cervical intraepithelial neoplasia, while the control samples were collected from normal individuals. With special emphasis on clinical data and blood samples for the GWAS analysis, the collection of other bio-specimens was slow, and the pairing of specimens and clinical data was poor during the first stage. However, in the second stage, the pairing of the clinical data and its corresponding bio-specimens improved. At present, the samples procured and preserved in the bio-bank cover most regions of China and different ethnic groups for both the normal controls and cervical cancer patients of different pathological categories. This bio-bank of cervical cancer specimens from the Chinese population will greatly promote the studies of cervical cancer in China.

Cord stem-cell transplantation in Ontario: do we need a public bank?

Science.gov (United States)

Gassas, A

2011-06-01

It has been 21 years since the first successful use of umbilical cord blood as a source of donor cells for hematopoietic stem cell transplantation (HSCT). Over those years, cord blood transplantation (CBT) has shown marked success as an effective modality in the treatment of children and adults with hematologic malignancies, marrow failure, immunodeficiency, hemoglobinopathy, and inherited metabolic diseases. Furthermore, transplantation without full human leukocyte antigen (HLA) matching is possible and, despite a lower incidence of graft-versus-host disease, graft-versus-leukemia effect is preserved. More than 20,000 cbts have been performed worldwide. Ontario is the most populated province in Canada, and its cbt numbers have increased dramatically in recent years, but most of the umbilical cord blood units are purchased from unrelated international registries. There is no public cord bank in Ontario, but there is a private cord banking option, and notably, Ontario has the largest number of live births in Canada [approximately 40% of all Canadian live births per year occur in Ontario (Statistics Canada, 2007)]. In this brief review, the pros and cons of private and public cord banking and the feasibility of starting an Ontario public cord bank are discussed.

Yet, donor deferral criteria seem to be strongly based on the precautionary principle protecting safety and quality, and on supply and expense considerations. This review therefore provides an overview of the available evidence on donor exclusion criteria, as well as on their cost-effectiveness, for the most frequent reasons of donor deferral in our region. PubMed was queried to retrieve primary research studies, systematic reviews, and health technology assessments (HTAs concerning donor exclusion criteria. With a similar approach, HTAs about the different blood-banking safety interventions were included. Reasons for donor deferral were recorded via the blood bank information system of the Belgian Red Cross-Flanders. Seven systematic reviews were identified: four on donor safety (hypotension, hypertension/type 2 diabetes, epilepsy, and higher age and three on recipient safety (hemochromatosis, men who have sex with men, and endoscopy. Forty-three low-quality observational studies were included, as well as 16 HTAs: three about donor exclusion criteria and 13 cost-utility analyses about blood-banking safety interventions. In general, the available evidence for deferral reasons was of low quality, and for 60% of the top 30 reasons for excluding donors, no evidence was found. Blood banking shows its unique position as many safety measures far exceed the normally accepted cost of €50,000/quality-adjusted life-years. The historical model based on the precautionary principle and on supply and expense considerations provides adequate supplies of

In order to examine the effects of chronic low G acceleration on blood flow distribution and cardiac output, chickens (N.10) were centrifuged at +2Gz for 30-61 d. Controls (N.12) were not centrifuged. The animals were anesthetized with sodium pentobarbital after removal from the centrifuge and surgically prepared in order to measure cardiac output and regional blood flows by the reference sample method with 85 Sr labeled microspheres (15 +/- 5 mum diam.). Both brachial arteries were cannulated to withdraw timed, paired blood samples at a known rate. The chest was opened and a cannula inserted into the left ventricle for administration of microspheres. Tissue samples were taken after completion of experimental procedures and their radioactivity was determined. The cardiac outputs in the two groups were not significantly different. Regional blood flows to the kidney, eyes, and skeletal muscle were significantly increased in the animals subjected to chronic +2Gz. While the mechanism by which these increases in blood flow occurred is not known, results indicate that chronic exposure to hyperdynamic gravitational fields can alter circulatory dynamics. We conclude that the cardiovascular system is directly involved in the process of adaptation to chronic positive acceleration

Umbilical cord blood donation: public or private?

Science.gov (United States)

Ballen, K K; Verter, F; Kurtzberg, J

2015-10-01

Umbilical cord blood (UCB) is a graft source for patients with malignant or genetic diseases who can be cured by allogeneic hematopoietic cell transplantation (HCT), but who do not have an appropriately HLA-matched family or volunteer unrelated adult donor. Starting in the 1990s, unrelated UCB banks were established, accepting donations from term deliveries and storing UCB units for public use. An estimated 730 000 UCB units have been donated and stored to date and ~35 000 UCB transplants have been performed worldwide. Over the past 20 years, private and family banks have grown rapidly, storing ~4 million UCB units for a particular patient or family, usually charging an up-front and yearly storage fee; therefore, these banks are able to be financially sustainable without releasing UCB units. Private banks are not obligated to fulfill the same regulatory requirements of the public banks. The public banks have released ~30 times more UCB units for therapy. Some countries have transitioned to an integrated banking model, a hybrid of public and family banking. Today, pregnant women, their families, obstetrical providers and pediatricians are faced with multiple choices about the disposition of their newborn's cord blood. In this commentary, we review the progress of UCB banking technology; we also analyze the current data on pediatric and adult unrelated UCB, including the recent expansion of interest in transplantation for hemoglobinopathies, and discuss emerging studies on the use of autologous UCB for neurologic diseases and regenerative medicine. We will review worldwide approaches to UCB banking, ethical considerations, criteria for public and family banking, integrated banking ideas and future strategies for UCB banking.

The necessity of strengthening the cooperation between tissue banks and organ transplant organizations at national, regional, and international levels.

The donation of tissues and organs increases significantly when tissue banks and organ transplant organizations work together in the procurement of organs and tissues at donor sources (hospitals, coroners system, organ procurement agencies, and funeral homes, among others). To achieve this important goal, national competent health authorities should considered the establishment of a mechanism that promote the widest possible cooperation between tissue banks and organ transplant organizations with hospitals, research medical institutions, universities, and other medical institutions and facilities. One of the issues that can facilitate this cooperation is the establishment of a coding and traceability system that could identify all tissues and organs used in transplant activities carried out in any country. The promotion of national, regional, and international cooperation between tissue banks and organ transplant organizations would enable the sharing of relevant information that could be important for medical practice and scientific studies carried out by many countries, particularly for those countries with a weak health care system.

The aim of this study was to determine the rate of blood component wastage before and after interventions at Yazd Blood Transfusion Center. The growing need for blood components along with blood safety issues and rising costs constantly pressurise blood centres to improve their efficiency. Reducing the quantity of discarded blood at all stages of the supply chain can decrease the total costs. Data on discarded blood components were extracted from the database of Yazd Blood Transfusion Center. Multiple interventions, including implementation of wastage management standard operating procedures and reduction of red blood cells (RBCs) inventory level, were implemented. Discard rates of blood components in the 3 years after intervention (2013-2015) were compared with the discard rates in the 3 years before interventions. The total wastage rate of blood components decreased by almost 60%. Discard rates of RBCs, platelets and plasma decreased from 9·7%, 18·5% and 5·4% to 2·9%, 10·5% and 2·3%, (P supply saving. © 2017 British Blood Transfusion Society.

Puerto Rico has eight hospital blood banks and three community blood banks for a population around four million. The Red Cross has been in existence in Puerto Rico since 1893 under the Spanish Governance but it was not until 1907 which became the American Red Cross (ARC). Since then it has been serving Puerto Rico and the U.S. Virgin Islands. About 171.222 blood components, which 45% are of the ARC, are used. There are a number of variations in utilization and a number of factors that are influencing us at the national and local level and that is why collaboration is required in the management plan of blood components at each hospital and implementation of maximum units required for each case of surgery.

Cord blood banking has become more popular in recent years. Checking cord blood complete blood count (CBC) and white blood cell (WBC) differential counts (DCs) is essential before cryopreserving the cord blood units. Therefore, establishing the normal reference values of cord blood CBC and WBC DC is important in clinical practice and research. To obtain a large-scale population-based normal CBC and WBC DC reference values of healthy neonates' cord blood from a public cord blood bank and to investigate the influence of the gender and delivery route. From September 2001 to November 2006, the cord blood of healthy Taiwanese neonates with gestational age 36 weeks and more were collected by Tzu Chi Cord Blood Bank with written informed consents. All cord blood samples were analyzed by Sysmex XE2100 automated hematology analyzer (Sysmex Corporation, Kobe, Japan) to obtain the CBC. The WBC DC was calculated by manual method. We used Student's t test and Mann-Whitney U test for investigating the influences of gender and delivery route on the CBC and WBC DC reference values. The results were presented by mean±standard deviation or 2.5-97.5th percentiles. In the study period, totally 5602 cord blood samples were collected eligibly for analysis. The cord blood CBC and WBC DC normal reference values were calculated. The female neonates had significantly higher mean corpuscular volume, platelet count, and WBC count, but lower red blood cell (RBC) count, hemoglobin (Hb), hematocrit, and mean corpuscular Hb concentration values (pTaiwan.

The transplantation of whole skeletal muscles is a common clinical procedure. Although atypical blood flows have been reported in small free muscle grafts, the blood flow of large neurovascular-intact (NVI) and neurovascular-anastomosed (NVA) grafts have not been measured. Because the maximum specific force (N/cm 2 ) of NVI and NVA grafts is 65% that of control muscles, we hypothesized that total and regional blood flows of NVI and NVA grafts at rest and during twitch contractions are significantly lower than lower flows of control muscles. In rabbits, blood flows of control rectus femoris (RFM) muscles and NVI and NVA grafts of RFM muscles were measured by the radioactive-microsphere technique. Total blood flows in grafts were not different from the control RFM muscle values, except for a higher resting flow in NVA grafts and a lower flow at 3 Hz in NVI grafts. Minor variations in regional flows were observed. We conclude that the operative procedures of grating and repair of blood vessels affect the vascular bed of muscles minimally, and the deficits observed in grafts do not arise from inadequate perfusion

The regional cerebral blood flow (CBF) was determined on seventeen patients with brain tumors. Ring type single photon emission CT (SPECT) was used following intravenous injection of 133 Xe. Case materials included eleven meningiomas and six malignant gliomas. Evaluation was performed with emphasis on the following points; 1. Correlation of the flow data within tumors to the angiographic tumor stains, 2. Influence of tumors on the cerebral blood flow of the normal brain tissue, 3. Correlation between degree of peripheral edema and the flow data of the affected hemispheres. There was significant correlation between flow data within tumors and angiographic tumor stains in meningiomas. Influence of tumors on cerebral blood flow of the normal tissue was greater in meningiomas than in gliomas. There was negative correlation between the degree of peripheral edema and the flow data of the affected hemisphere. It has been concluded that the measurement of CBF in brain tumors is a valuable method in evaluation of brain tumors. (author)

Umbilical cord blood (UCB) stem cells allow the transplantation of partially human leukocyte antigen (HLA)-matched grafts and are a valuable resource for the treatment of hematologic malignancies and heritable hematologic, immunologic and metabolic diseases, especially when a compatible bone marrow donor is unavailable. The aim of this study was to determine how many ethnic groups in Iran are covered by the available UCB units based on HLA diversity. From 2009 until mid-2013, 4,981 (30.3%) of the 16,437 UCB samples collected met the storage criteria and were cryopreserved at a public cord blood bank (CBB) in Tehran, Iran. HLA-A, -B and -DRB1 were typed in 1,793 samples. The mean volume of the cryopreserved samples was 81.25 ± 20.3 ml. The range of total nucleated cells per unit was 51 × 10(7)-107 × 10(7). The most common HLA alleles were HLA-A*2 (17%) and HLA-A*24 (15.6%), HLA-B*35 (16.8%) and HLA-B*51 (13.9%), and HLA-DRB1*11 (20%) and HLA-DRB1*15 (14%). The predominant haplotypes were HLA-A*24-B*35-DRB1*11 (2%), HLA-A*02-B*50-DR*07 (1.8%), and HLA-A*02-B*51-DRB1*11 (1.5%). Based on the HLA-DRB1 profiles, the UCB units available at the Royan public UCB bank are a potentially adequate resource for hematopoietic stem cell transplantation for Iranian recipients belonging to particular ethnic groups. Regular educational programs to improve the public knowledge of UCB for transplantation can enhance the public CBB stocks for all Iranian ethnic groups in the future.

2015-12-01

The purpose of the study is to forecast the outflow and inflow of currency at Indonesian Central Bank or Bank Indonesia (BI) in Sulawesi Region. The currency outflow and inflow data tend to have a trend pattern which is influenced by calendar variation effects. Therefore, this research focuses to apply some forecasting methods that could handle calendar variation effects, i.e. Time Series Regression (TSR) and ARIMAX models, and compare the forecast accuracy with ARIMA model. The best model is selected based on the lowest of Root Mean Squares Errors (RMSE) at out-sample dataset. The results show that ARIMA is the best model for forecasting the currency outflow and inflow at South Sulawesi. Whereas, the best model for forecasting the currency outflow at Central Sulawesi and Southeast Sulawesi, and for forecasting the currency inflow at South Sulawesi and North Sulawesi is TSR. Additionally, ARIMAX is the best model for forecasting the currency outflow at North Sulawesi. Hence, the results show that more complex models do not neccessary yield more accurate forecast than the simpler one.

Good blood banking practice requires that every effort should be made to detect any deviation or defect in blood bank products and to identify any potential risk to blood donor or recipient(s). We report the findings of an exercise that provide an insight into why feedback from the user side is crucial. Various events involving blood bags and plateletpheresis kits and the corresponding appropriate actions instituted for remedial measures were recorded. These scattered events were recorded for 6 months following the use of a new batch of improved blood bags with add-on features. Several events related to plateletpheresis kits from three different manufacturers were also recorded for 1 year. The affected blood bags were utilized with no untoward incident. The complaint was closed following satisfactory response from the blood bag manufacturing company that acted in a timely manner in addressing the root causes of the problems. However, corrective and preventive actions (CAPA) could not be implemented for plateletpheresis kits. The rate of undesirable events was higher with plateletpheresis kits as compared with whole blood bags (1.75% vs. 0.06%). As defects or deviations that trigger the need for CAPA can stem from numerous sources, it is important to clearly identify and document the problems and level of risk so that appropriate investigations can be instituted and remedial actions can be taken in a timely manner. This study demonstrates the usefulness of a quality initiative to collate and analyze blood product faults in conjunction with blood product manufacturers. © 2012 American Association of Blood Banks.

Using the H I emission/absorption method, we resolve the kinematic distance ambiguity and derive distances for 149 of 182 (82%) H II regions discovered by the Green Bank Telescope H II Region Discovery Survey (GBT HRDS). The HRDS is an X-band (9 GHz, 3 cm) GBT survey of 448 previously unknown H II regions in radio recombination line and radio continuum emission. Here, we focus on HRDS sources from 67 Degree-Sign {>=} l {>=} 18 Degree-Sign , where kinematic distances are more reliable. The 25 HRDS sources in this zone that have negative recombination line velocities are unambiguously beyond the orbit of the Sun, up to 20 kpc distant. They are the most distant H II regions yet discovered. We find that 61% of HRDS sources are located at the far distance, 31% at the tangent-point distance, and only 7% at the near distance. 'Bubble' H II regions are not preferentially located at the near distance (as was assumed previously) but average 10 kpc from the Sun. The HRDS nebulae, when combined with a large sample of H II regions with previously known distances, show evidence of spiral structure in two circular arc segments of mean Galactocentric radii of 4.25 and 6.0 kpc. We perform a thorough uncertainty analysis to analyze the effect of using different rotation curves, streaming motions, and a change to the solar circular rotation speed. The median distance uncertainty for our sample of H II regions is only 0.5 kpc, or 5%. This is significantly less than the median difference between the near and far kinematic distances, 6 kpc. The basic Galactic structure results are unchanged after considering these sources of uncertainty.

Crass, M.F. III; Lust, R.M.

1986-01-01

Although low doses of the biologically-active fragment of parathyroid hormone PTH-(1-34), have been shown to produce potent dilation of the coronary circulation specific regional and transmural (endo/epi) myocardial blood flow (MBF) responses to the hormone have not been described. Anesthetized open-chest mongrel dogs were instrumented to quantitate coronary blood flow and other cardiodynamic parameters. PTH-(1-34) was infused into the left circumflex artery (.008 nmol kg -1 min -1 ). Using the reference withdrawal method, radionuclide-labeled microspheres were injected before (basal flow), during (8 min after new steady-state flow), and after (restoration of basal flow) a 20 min infusion of PTH-(1-34). MFB increased from 76 +- 1.9 to 152 +- 3.5 ml min -1 100 g -1 (P < .001) during PTH-(1-34) infusion. No differences in endo/epi flow ratio or regional coronary blood flow within the left ventricle were detected. Thus, in anesthetized dogs, the increase in MBF observed secondary to the PTH-(1-34)-induced decrease in coronary resistance appeared to be uniform transmurally and regionally, and is probably not the result of a shunting or steal phenomenon

In patients with hypertensive intracerebral hemorrhages, changes in the regional cerebral blood flow (rCBF) after drug-induced blood-pressure reduction were examined by means of subtraction SPECT. The subjects were 38 patients with hypertensive intracerebral hemorrhages; 22 were putaminal hemorrhages (mean age, 56.8 years; mean hematoma volume, 18.4 cc), while 16 were thalamic hemorrhages (mean age, 61.9 years; mean hematoma volume, 7.8 cc). The rCBF was measured by means of SPECT (Tomomatic 64) with 133 Xe inhalation. Trimethaphan (an autonomic ganglion blocker) and diltiazem hydrochloride (a calcium antagonist) were used for the reduction of the blood pressure. The results were as follows: In the acute stage, the mean CBF was reduced when the blood pressure fell by more than 20% in both the putaminal hemorrhages and the thalamic hemorrhages. A similar tendency was observed in the subacute stage, except that a greater reduction in the blood pressure was needed to induce mean CBF reduction. The subtraction of rCBF maps before and after hypotension treatment shows a reduction of the rCBF in the lateral region of hematoma and the contralateral hemisphere. (author)

There is a lack of data on the prevalence of pre-high blood pressure (PreHBP) and high blood pressure (HBP), based on recent international blood pressure references, in non-overweight children and adolescents. To describe the prevalence of PreHBP and HBP in non-overweight children and adolescents in developed regions of China. In total, 588 097 non-overweight children and adolescents aged 6-17 years from the National Surveys on Chinese Students' Constitution and Health in 2015 were included. The prevalence of PreHBP was 13.41% and subjects in urban areas had a higher prevalence of PreHBP (14.14%) than those in rural areas (12.92%). Subjects in regions with a high (13.56%) or moderate (13.61%) socioeconomic status showed a higher prevalence of PreHBP than those in regions with a relatively low socioeconomic status (12.76%). A similar pattern was found for the prevalence of HBP, and the prevalence of HBP was 18.25% for all participants, 20.55% for subjects in urban areas, 16.71% in rural areas, 18.76% in high socioeconomic areas, 18.62% in moderate socioeconomic areas and 16.70% in relatively low socioeconomic areas. A large proportion of non-overweight children and adolescents had elevated blood pressure and there were urban-rural and socioeconomic disparities in the prevalence of elevated blood pressure.

Full Text Available Intensification of financial development during last decade causes transformation of banking sector functioning. In particular, among the most significant changes over this period should be noted the next ones: convergence of financial market segments and appearance of cross-sector financial products, an increase of prevailing of financial sector in comparison with real economy and level of their interdependent, an intensification of crisis processes in financial and especially banking sector and a significant increase of the scale of the crisis consequences etc. thus, in such vulnerable conditions it is become very urgent to identify the relevant factors that can influence on the stability of banking sector, because its maintenance seems to be one of the most important preconditions of the stability of the national economy as a whole. Purpose of the article is to analyze key performance indicators of the Ukrainian banking system, clarify its main problems, identify relevant factors of the stability of the Ukrainian banking system and the character of their influence on the dependent variable. Realization of the mentioned above tasks was ensured by regression analysis (OLS regression. Analysis of key indicators that characterize current situation in the Ukrainian banking system found out the existence of numerous endogenous and exogenous problems, which, in turn, cause worsening most of analyzed indicators during 2013-2015. Unfavorable situation in Ukrainian banking system determined the necessity of identification of relevant factors of banking system stability to avoid transmission of financial shocks. According to the results of regression analysis on the stability of banking sector positively influence such factors as increase of interest margin to gross income ratio, reserves to assets ratio, number of branches, ratio of non-performing loans to total loans. Meanwhile, negative impact on stability of banking system has an increase of liquid

Regional cerebral blood flow in patients with hypertensive intracerebral hemorrhage

International Nuclear Information System (INIS)

Kuroda, Kiyoshi

1982-01-01

Regional cerebral blood flow (rCBF) was measured in 36 patients with hypertensive intracerebral hemorrhage (putaminal hemorrhage) treated surgically, using the Xenon-133 intracarotid injection method. The correlations between CBF in four regions, (the hemisphere, the frontal region, the sensori-motor area and the focal area) and the duration from the operation, the conscious level, the hematoma volume and motor function were investigated. Mean cerebral blood flow (MCBF), rCBF in sensori-motor area and in the focal area showed a value below 30 ml/100g/min. for any duration after the operation within one year. However, in the frontal region rCBF tends to increase from 4 months after the operation. There was a close correlation between the conscious level and CBF, especially in the frontal region. The higher CBF was noted in the better consciousness group. In hematoma cases the larger the hematoma volume (especially those over 31 ml)the lower the CBF in all three regions. In the focal area rCBF showed the lowest value among these three regions and was dependent on the hematoma volume, while frontal region revealed the highest flow value of them all, even in cases with a hematoma volume over 81 ml. There was a significant difference in rCBF between cases with severe motor disturbance and cases with moderate motor disturbance, except in the focal area. In the frontal region rCBF coincides rather well to the degree of motor disturbance. While, rCBF in the focal area was less than 30 ml/100g/min., and showed no correlation to motor function.

These measurements will provide comprehensive and robust results of efficiency of individual bank compare to its peer group. The results using parametric SFA show that in 2002, conventional banks (0.79 were slightly more efficient than Islamic banks (0.77, while in 2003, the efficiency of Islamic banks improved to 0.84 and the efficiency of conventional banks worsen to 0.76, so that Islamic banks have become more efficient than conventional banks. Conventional and Islamic banks have been improving and converged to the highest level of efficiency (1.00 since 2004. The DFA results show that conventional banks (0.89 are only slightly more efficient than Islamic banks (0.87. Conventional public bank (0.93 is the most efficient, while Islamic regional bank (0.84 is the least efficient. Moreover, efficient banks (conventional and Islamic do not always have lower OCOI (operating costs divided by operating income, while banks with better OCOI usually are more profitable (have better return on assets or ROA. Therefore, technically, Islamic banks have shown their readiness to compete head to head with their conventional counterparts. However, other aspects, such as, number of networks and branches, service quality, convenience, products and services provided, human resources, and pricing, should have become the next priorities for improvements.JEL Classification : C10, C33, G21, G28Keywords : Islamic Banking, Efficiency, Stochastic Frontier Approach, Distribution Free Approach

Regional simulations of the Faroe Bank Channel overflow using a σ-coordinate ocean model

Science.gov (United States)

Seim, Knut S.; Fer, Ilker; Berntsen, Jarle

Gravity-driven overflow of cold, deep and intermediate water from the Norwegian Sea through the Faroe Bank Channel carries significant volume flux and contributes to the ventilation of the deep North Atlantic Ocean. Here we present results from regional simulations of the Faroe Bank Channel overflow using a terrain-following ( σ-coordinate) ocean model with fine resolution near the sea bed. The model results are compared with observations of hydrography, currents and turbulence conducted in 2008. Turbulent dissipation rate and eddy diffusivity profiles inferred from the observations are used in refining the parameters of the turbulence closure. The model reproduces the observed vertical structure of the enhanced dissipation and diffusivity in the bottommost 50-60 m exceptionally well. In this region, shear-induced mixing dominates and is found to be well-represented by the applied second order turbulence closure models. Farther away from the boundary, however, in the 100-m thick interfacial layer and above the plume-ambient interface, the model does not resolve the observed mixing. The contribution of turbulence from breaking internal waves is one of the processes not represented in the model with significant consequences for observed entrainment and mixing. Regular sub-inertial oscillations (eddies) at 4-4.5 day period develop downstream of the sill, consistent with the observations. When averaged over several eddy events, the evolution of section-averaged plume properties over the oscillation period shows that the eddies significantly affect mixing and the descent rate of the plume. At a section 60 km downstream of the sill, eddies lead to periodic and abrupt cross-isobath descent of the overflow plume and an increase in dissipation rate by one order of magnitude.

Regional cerebral blood flow (rCBF) in psychiatry: Methodological issues

International Nuclear Information System (INIS)

Prohovnik, I.

1984-01-01

Traditionally, measurements of regional cerebral blood flow (rCBF) have been confined to neurology and nuclear medicine. Only one laboratory had concentrated on using this technique in psychiatric studies. Recently, however, rCBF has been increasingly used in psychiatry, and it seems appropriate at this time to examine the value and limitations of this method. The present article reviews selected methodological issues that may complicate the performance and interpretation of rCBF studies, with the aim of providing some means to evaluate published work and to plan further psychiatric research. In this paper, the term rCBF refers only to the two-dimensional, noninvasive methods that rely on inhalation or intravenous injection of xenon-133. The growing interest of rCBF to psychiatry stems mostly from the fact that this technique can indirectly map cerebral metabolism and, by interface, neural activity or information processing. Regional metabolism and blood flow are closely coupled to the human brain in the absence of gross pathology, and since psychiatric patients rarely present acute neurological abnormalities that might disrupt this coupling, one may infer regional metabolism from flow

The relationship between the spatial distribution of thallium-201 in myocardial perfusion scintigrams and the distribution of left ventricular regional myocardial blood flow was examined in 25 patients undergoing coronary arteriography. Thallium-201 myocardial scintigrams were obtained after symptom-limited exercise and after a 4 hr delay. Regional myocardial blood flow was measured by the xenon-133 clearance method in patients at rest and during rapid atrial pacing to a double product comparable with that achieved during exercise stress testing. Patterns of regional thallium-201 activity and regional myocardial blood flow, recorded in similar left anterior oblique projections, were compared for left ventricular segments supplied by the left anterior descending (LAD) and left circumflex (CIRC) arteries. In 11 patients without significant lesions of the left coronary artery (group 1), thallium-201 was homogeneously distributed in the LAD and CIRC distributions in scintigrams taken during peak exercise; these scintigrams correspond to homogeneous regional myocardial blood flow in the LAD and CIRC regions during pacing-induced stress. In 14 patients with significant lesions of the left coronary artery (group 2), ratios of regional thallium-201 activity in the LAD and CIRC distributions of exercise scintigrams correlated well (r . .84) with ratios of regional myocardial blood flow measured during rapid pacing. Background subtraction altered the relationship between relative thallium-201 uptake and regional myocardial blood flow, causing overestimation of the magnitude of flow reduction on exercise scintigrams

Tsabang, Nole; Yedjou, Clement G; Tchounwou, Paul B

2017-01-01

High blood pressure is a public health challenge worldwide. According to World Health Organization, 30% of men and 50% of women 65 to 75 years old are suffering from high blood pressure. The number of hypertensive patients in the world will attain 1.56 billion of people, with 60% increase in prevalence. The incidence of high blood pressure increases with age, but nowadays, is being noticed an increasing incidence in young people. The socio-cultural medicine may provide new solutions in the management of this pathology. Therefore this study was carried out to record and document plants used against high blood pressure in socio-cultural medicine for future drugs discovery worldwide. An ethno botanical survey was realized between 2002 and 2016 to identify manifold plants used to fight against high blood pressure. This survey was carried out in three phytogeographic regions of Cameroon. Amongst people living in those regions, 1131 randomly screened interviewees distributed in 58 socio-cultural groups were involved in this study. This survey reveals that about 70% of interviewees don't know high blood pressure which is a symptomless disease. A total of 28 species of plants were recorded. These plants belong to 25 genera and 24 families. They were used to prepare 28 herbal remedies for the treatment of high blood pressure. In the morphological point of view about 10/28 (36%) plants are herbs; 9/28 (32%) plants are trees and 9/28 (32%) plants are shrubs. Only 3/28 plants (11%) used including Allium sativum, Aloe barteri and Aloe buttneri) are cultivated. This means that the plants used in this study don't usually have some form of protection through cultivation which is encouraging in terms of their conservation. The uncontrolled use of a hypotensive plants can provoke a fatal hypotension in hypertensive patients. Therefore the use of hypotensive plants needs to be controlled by physician or by a patient verification using a blood pressure monitor. Recorded species which

Full Text Available The purpose of the paper is to work out and characterize bank business models that are formed in Ukraine. Methodology. Our research we will spend among banks that are functioning on the Ukrainian financial market and are not on the stage of liquidation, so the sample under study in our work is comprised of 131 banks which are different in their ownership structure and size. The core of the methodology is a statistical clustering algorithm that allows identifying the groups of banks (clusters with similar business models as banks with similar business model strategies have made similar choices regarding the composition of their assets and liabilities. The cluster analyses were taken on the base of seven chosen indicators: bank loans, bank liabilities, enterprise loans, enterprise liabilities, household loans, household liabilities and trading assets. Results. The traditional business model of bank is worked out. The bank business models that are functioning in Ukraine are identified on the base of cluster analyses using balance sheet characteristics of 131 Ukrainian banks. We find that in Ukraine were formed three types of bank business models: “Focused retail”, “Diversified retail” and “Corporative retail”. The description of each model is given. Practical implications. More detailed research of distinguished models allows not only to find out the main advantages and disadvantages of each bank model, but also the main problems that follow the development of Ukrainian banking sector. Identifying of bank models and their studying simplifies searching and elaboration of regulatory instruments as there is a two-way causation between regulation and bank business models. This implies a symbiotic relationship between regulation and bank business models: business models respond to regulation which in turn responds to the evolution of new business models. Value/originality. Such survey is conducted at the first time among Ukrainian banks. The

1994-06-01

Regional cerebral blood flow (rCBF) was evaluated in 63 patients with Parkinson's disease (PD) by single-photon emission computed tomography (SPECT) using N-isopropyl-p-[sup 123]I-iodoamphetamine ([sup 123]I-IMP) as a tracer. Evaluation of the SPECT images was performed in accordance with the rCBF quantification method using a microsphere model. Patients in stage IV demonstrated significantly lower rCBF than those in stage II at the frontal, temporal, parietal, occipital regions and in the thalamus and cerebellum. Subjects with mental symptoms demonstrated decreased rCBF in every region in the brain. The present study indicates that clinical exacerbation and manifestation of dementia and other psychiatric symptoms in Parkinson's disease are associated with decreased blood flow in various brain regions.

Harris, G E; Cloud, S; Myhre, B A

1977-01-01

Blood should not be allowed to exceed 10 C while being stored or transported. However, one cannot test the internal temperature of a unit of blood without contaminating it. Most blood banks have established an arbitrary time limit beyond which a blood unit cannot be kept out of the refrigerator. This method is ineffective if blood is stored in a satellite refrigerator, since the blood may be moved in and out of the refrigerator and the blood bank personnel will be unaware of it. An elapsed time indicator is described which employs a small condenser (E-Cell-Plessey Electronics) charged with a known amount of electricity. If the device is removed from the refrigerator, it begins to discharge at a known rate. The amount of time subsequently can be determined by the loss of charge. The prototype of this instrument has been found to be quite accurate and small (2 inches X 2 inches X 1 inch). It would be rather inexpensive if made in considerable numbers.

Previous studies have suggested that the cystic change of pituitary adenoma might be related to the blood supply and metabolism of the tumor; however, the exact pathologic mechanism underlying the cystic change remains unknown. We aimed to assess the features of regional blood supply of pituitary adenoma and examine its relationship with the cystic change of pituitary adenoma. Patients (N = 79) with pituitary adenoma admitted to our hospital were divided into the parenchyma group (n = 40) or the cystic change group (n = 39). Dynamic contrast-enhanced magnetic resonance imaging of the pituitary adenoma was conducted for the parenchyma group and the steepest slopes (SS max , reflecting regional blood supply) at different areas were calculated. The location of cystic change of the pituitary adenoma was recorded and analyzed for the cystic change group. The parenchyma group showed an upper SS max of 2.52 ± 1.18, a lower SS max of 2.89 ± 1.46, a left SS max of 2.71 ± 1.31, and a right SS max of 2.66 ± 1.29. The difference between the upper and lower SS max was statistically significant (P supply is unevenly distributed in the parenchymal pituitary adenoma, with reduced blood supply in the upper than the lower region. Cystic change mainly occurs in the upper region of pituitary adenoma. Copyright © 2017 Elsevier Inc. All rights reserved.

To determine the value of the initial phase of the Tc-99m DTPA renogram in the direct estimation of relative renal blood flow in dogs, the ratios of the slopes of renal time-activity curves were compared with the ratios of measured blood flow. Radionuclide results were dependent on region-of-interest (ROI) and background ROI assignment, and correlated well with measured relative flow only with a maximum renal outline region. Curve slope ratios correlated well with measured flow ratios with and without background correction, while 1- to 2-minute uptake ratios correlated well only when corrected for background

The effects of activation procedures on regional cerebral blood flow in humans

International Nuclear Information System (INIS)

Rozenfeld, D.; Wolfson, L.I.

1981-01-01

Regional cerebral blood flow (r-CBF) can be measured using 133XE and collimated detectors. The radionuclide can be administered either by inhalation or intracarotid injection. Comparison of blood flow determinations at rest and during performance of an activity identifies those brain regions that become active during the performance of the activity. Relatively specific patterns of r-CBF are observed during hand movements, sensory stimulation, eye movements, speech, listening, and reading. Regional CBF changes during reasoning and memorization are less specific and less well characterized. It is clear that brain lesions affect r-CBF responses to various activities, but this effect has not been well correlated with functional deficits or recovery of function. Regional CBF measurement gives information about brain activity and the functional response to experimental manipulation. This approach may well add to our understanding of normal, as well as pathologic, brain functioning

Full Text Available OBJECTIVE: In 1998, the Brazilian Ministry of Health made it mandatory for all blood banks in the country to screen donated blood for human immunodeficiency virus (HIV concomitantly using two different enzyme immunoassay (EIA tests. Concerned with the best use of available resources, our objective with this study was to evaluate the usefulness of conducting two EIA screening tests instead of just one. METHODS: We analyzed data from 1999 through 2001 obtained by testing 698 191 units of donated blood using two EIA HIV screening tests concomitantly at the Pro-Blood Foundation/Blood Center of São Paulo (Fundação Pró-Sangue/Hemocentro de São Paulo, which is a major blood center in the city of São Paulo, Brazil. All samples reactive in at least one of the two EIA tests were submitted for confirmation by a Western blot (WB test, and the persons who had donated those samples were also asked to return and provide a follow-up sample. RESULTS: Out of the 698 191 blood units that were donated, 2 718 of them (0.4% had to be discarded because they were reactive to at least one of the EIA tests. There were two WB-positive donation samples that were reactive in only one HIV EIA screening test. On their follow-up samples, both donors tested WB-negative. These cases were considered false positive results at screening. Of the 2 718 donors who were asked to return and provide a follow-up sample, 1 576 of them (58% did so. From these 1 576 persons, we found that there were two individuals who had been reactive to only one of the two EIA screening tests and who had also been negative on the WB at screening but who were fully seroconverted on the follow-up sample. We thus estimated that, in comparison to the use of a single EIA screening test, the use of two EIA screening tests would detect only one extra sample out of 410 700 units of blood. CONCLUSIONS: Our data do not support the use of two different, concomitant EIA screening tests for HIV. The great

Rahmatina A. Kasri

2017-08-01

Full Text Available Bank run is an important economic phenomenon which increasingly occurred in in modern banking system and potentially threatened banking stability as it could trigger a banking crisis. However, most studies related to bank run focus on the occurrence of bank run in conventional banking system. Very few of them discuss the bank run phenomenon under Islamic banking system or dual banking system where Islamic banks jointly operating with conventional banks. Therefore, this study attempts to analyze the determinants of bank run in the Indonesian Islamic banking industry by employing primary data from 256 customers of Indonesia Islamic banks in 2015 and by utilizing factor analysis and descriptive statistics. In theory, Islamic banks tend to be more resilient towards any macroeconomic or financial shocks as compared to conventional banks due to the nature of its asset-based and risk-sharing arrangement. However, the result exhibits that both psychological and fundamental factors (i.e. macroeconomics and bank fundamentals strongly influence the behaviors of Islamic banking depositors to withdraw their funds, which might trigger the occurrence of bank runs in the country. Insider information, macroeconomic condition and bank fundamental factors are also shown to have the highest impacts among all variables. Hence, in the context of banking stability, the finding implies that Islamic banks are not completely immune to the impacts of macroeconomic shocks or financial crisis. As a country with a dual banking system, Indonesia had experienced several bank runs since 1990s. Therefore, the findings of the study should provide the policy makers important insight into research based-policy in order to attain financial stability as one of the main economic goals of the country.

Bank Diversification Effects on Bank Performance and Risk Profile of Bank in Indonesia

Directory of Open Access Journals (Sweden)

Anthony Lukmawijaya

2015-05-01

Full Text Available We investigate the relationship of Indonesian bank diversification towards its long term performance and risk profile with Indonesian bank data from 2009 to 2013. Non-interest income to total operating income of the bank measures its bank diversification level. Bank value is measured by the adjusted Tobin's Q and risk profile which is broken down into total risk, idiosyncratic risk, and systematic risk. The result shows that bank non-interest income diversification has a positive influence on its franchise value. There is, however, no strong evidence that diversification can lower a bank's risk profile.

Principles of the tracer method in assessing regional blood flow

Potchen, E.J.; Siegel, B.; Meidinger, R.

1972-01-01

The standard brain scan is abnormal when there is relative increase in blood volume or when there is an abnormal permeability to substances which normally cannot enter the brain tissue. The usual mechanism of abnormal permeability is based upon neovascularity in tissues which do not maintain the tight junctions one sees in the normal brain endothelium. These tight junctions prohibit the leakage of materials from the intra- to extravascular space, and when they are not available many materials can readily transit into the abnormal tissue substance and can therefore be discerned on a standard brain scan. In many instances, however, there is no gross breakdown in this blood-brain barrier, but more subtle derangement may be detected by determining changes in regional brain blood volume or the relative volume of distribution of various labeled materials. We have studied whether or not we can discern differences in brain spaces of two isotopes in experimental situations where the brain scan would be normal. For these models, we have used water-induced brain edema and triethyl-tin-induced brain edema in the experimental animal. In water intoxication, there is no difference in the microvascular anatomy or change in the 99 /sup m/Tc pertechnetate space, but it is apparent from our studies that the brain swells at the expense of brain blood volume and by measuring brain blood volume against brain mass, i.e., transit of 131 I antipyrine versus 51 Cr labeled red cells, one can detect brain edema in a situation where the brain scan would be normal. It is these approaches with cameras and computers using dual energies that may afford a more simplified estimation of altered regional brain function than is now available with the internal carotid injection technique.

Assessing regional cerebral blood flow in depression using 320-slice computed tomography.

Directory of Open Access Journals (Sweden)

Yiming Wang

Full Text Available While there is evidence that the development and course of major depressive disorder (MDD symptomatology is associated with vascular disease, and that there are changes in energy utilization in the disorder, the extent to which cerebral blood flow is changed in this condition is not clear. This study utilized a novel imaging technique previously used in coronary and stroke patients, 320-slice Computed-Tomography (CT, to assess regional cerebral blood flow (rCBF in those with MDD and examine the pattern of regional cerebral perfusion. Thirty nine participants with depressive symptoms (Hamilton Depression Rating Scale 24 (HAMD24 score > 20, and Self-Rating Depression Scale (SDS score > 53 and 41 healthy volunteers were studied. For all subjects, 3 ml of venous blood was collected to assess hematological parameters. Transcranial Doppler (TCD ultrasound was utilized to measure parameters of cerebral artery rCBFV and analyse the Pulsatility Index (PI. 16 subjects (8 =  MDD; 8 =  healthy also had rCBF measured in different cerebral artery regions using 320-slice CT. Differences among groups were analyzed using ANOVA and Pearson's tests were employed in our statistical analyses. Compared with the control group, whole blood viscosity (including high\\middle\\low shear rateand hematocrit (HCT were significantly increased in the MDD group. PI values in different cerebral artery regions and parameters of rCBFV in the cerebral arteries were decreased in depressive participants, and there was a positive relationship between rCBFV and the corresponding vascular rCBF in both gray and white matter. rCBF of the left gray matter was lower than that of the right in MDD. Major depression is characterized by a wide range of CBF impairments and prominent changes in gray matter blood flow. 320-slice CT appears to be a valid and promising tool for measuring rCBF, and could thus be employed in psychiatric settings for biomarker and treatment response purposes.

The tidal residual current may play an important role in the mean flow in the Changjiang Bank region, in addition to other residual currents, such as the Taiwan Warm Current, the Yellow Sea Coastal Current, and the Yellow Sea Warm Current. In this paper, a detailed structure of the tidal residual current, in particular the meso-scale eddies, in the Changjiang Bank region is observed from model simulations, and its role in the mean flow is quantified using the well-validated Finite Volume Coastal Ocean Model. The tidal residual current in the Changjiang Bank region consists of two components: an anticyclonic regional-scale tidal residual circulation around the edge of the Changjiang Bank and some cyclonic meso-scale tidal residual eddies across the Changjiang Bank. The meso-scale tidal residual eddies occur across the Changjiang Bank and contribute to the regional-scale tidal residual circulation offshore at the northwest boundary and on the northeast edge of the Changjiang Bank, southeastward along the 50 m isobath. Tidal rectification is the major mechanism causing the tidal residual current to flow along the isobaths. Both components of the tidal residual current have significant effects on the mean flow. A comparison between the tidal residual current and the mean flow indicates that the contribution of the tidal residual current to the mean flow is greater than 50%.

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

Umbilical cord blood may have therapeutic benefit in children with cerebral palsy (CP), but further studies are required. On first appearance it seems that Australia is well placed for such a trial because we have excellence in CP research backed by extensive CP registers, and both public and private cord blood banks. We aimed to examine the possibilities of conducting a trial of autologous umbilical cord blood cells (UCBCs) as a treatment for children with CP in Australia. Data linkages between CP registers and cord blood banks were used to estimate potential participant numbers for a trial of autologous UCBCs for children with CP. As of early 2013, one Victorian child with CP had cord blood stored in the public bank, and between 1 and 3 children had their cord blood stored at Cell Care Australia (private cord blood bank). In New South Wales, we counted two children on the CP register who had their stored cord blood available in early 2013. We estimate that there are between 10 and 24 children with CP of any type who have autologous cord blood available across Australia. In nations with small populations like Australia, combined with Australia's relatively low per capita cord blood storage to date, it is not currently feasible to conduct trials of autologous UCBCs for children with CP. Other options must be explored, such as allogeneic UCBCs or prospective trials for neonates at risk of CP. © 2014 The Authors.

2007-01-01

Pure dysarthria from brain infarction is a rare condition, and its pathophysiology remains unclear. To clarify the underlying mechanism of pure dysarthria, we investigated the lesion sites and regional cerebral blood flow in patients with pure dysarthria. We examined 18 consecutive patients with pure dysarthria (9 men and 9 women; mean age, 71 years) who underwent MRI and cerebral blood flow studies. To visualize the regional cerebral blood flow, we generated Z score images using the three-dimensional stereotactic surface projection (3D-SSP) method with single-photon emission computed tomography (SPECT) and N-isopropyl-p [ 123 I]iodoamphetamine. Data on the brain surface perfusion extracted by the 3D-SSP analysis were compared between the pure dysarthria (PD) patients and 9 control subjects. MRI revealed multiple lacunar infarctions involving the internal capsule and/or corona radiata in 11 patients, left internal capsule-corona radiata infarction in 4 patients, and pontine infarction in 3 patients. SPECT with 3D-SSP demonstrated bilateral frontal cortical hypoperfusion in all patients, particularly in the anterior opercular region. Based on intergroup comparisons, the PD group exhibited pronounced cortical hypoperfusion in the opercular and medial frontal regions, left more than right. In conclusion, pure dysarthria is considered to originate from frontal cortical hypoperfusion, mainly in the anterior opercular and medial frontal regions, which is probably due to interruption of the corticosubcortical neural networks relevant to speech expression and articulation. In addition, it is suggested that left hemispheric lesions may make a greater contribution to the development of pure dysarthria than do right ones. (author)

[Ethical aspects of human embryonic stem cell use and commercial umbilical cord blood stem cell banking. Ethical reflections on the occasion of the regulation of the European Council and Parliament on advanced therapy medicinal products].

Science.gov (United States)

Virt, G

2010-01-01

The regulation of the European Council and Parliament on advanced therapy medicinal products also includes therapies with human embryonic stem cells. The use of these stem cells is controversially and heavily discussed. Contrary to the use of adult stem cells, medical and ethical problems concerning the use of human embryonic stem cells persists, because this use is based on the destruction of human life at the very beginning. The regulation foresees, therefore, subsidiarity within the European Member States. Although there are no ethical problems in principle with the use of stem cells from the umbilical cord blood, there are social ethical doubts with the banking of these stem cells for autologous use without any currently foreseeable medical advantage by commercial blood banks. Also in this case subsidiarity is valid.

The main aims of this study were to (i) investigate the emotional disorder status of patients with burning mouth syndrome (BMS) and (ii) detect regional cerebral blood flow in BMS patients with the application of combined single-photon emission computed tomography and computed tomography (SPECT/CT). The degree of pain was measured using the visual analysis scale, and emotional disorder with the self-rating anxiety scale, self-rating depression scale, and Hamilton depression rating scale in 29 patients with BMS and 10 healthy controls. SPECT/CT was performed in 29 patients with BMS and 10 healthy controls, and statistical parametric mapping method was used for between-group analyses. The incidence rate of depression in patients with BMS was 31.0%. Compared to the control group, patients with BMS displayed significantly different depression and anxiety scales (P < 0.05). Significantly lower regional cerebral blood flow in the left parietal and left temporal lobes was recorded for BMS patients with depression (P < 0.05). Patients with BMS experience more depression and anxious emotion. Moreover, depression in patients with BMS may be associated with lower regional cerebral blood flow in the left temporal and left parietal lobes. © 2015 John Wiley & Sons A/S.

Whether central banks should play an active role in bank supervision and regulation is being debated both in the United States and abroad. While the Bank of England has recently been stripped of its supervisory responsibilities and several proposals in the United States have advocated removing bank supervision from the Federal Reserve System, other countries are considering enhancing central bank involvement in this area. Many of the arguments for and against these proposals hinge on the effe...

Sixteen former rayon viscose workers were investigated four years after the exposure to carbon disulfide was discontinued. Median age was 58 years (range 43-65 years), median exposure time was 17 years (range 10-35 years). Encephalopathy was diagnosed in altogether 14 workers. To further explore pathophysiological mechanisms, cerebrovascular investigations were employed. Doppler ultrasound examination of the precerebral vessels in 15 workers showed a slight stenosis of the left internal carotid artery in one. Regional cerebral blood flow investigation (rCBF) with single photon emission computerized tomography (SPECT) with Xenon-133 gas was performed in 14. There was no significant difference from a control group. Regional side-to-side asymmetries beyond reference limits were demonstrated in eight workers. The abnormalities were modest, but may indicate a tendency toward focal blood flow disturbances in workers with long-term exposure to carbon disulfide. (au)

Estimated 236,548 People Living with HIV (PLHIV) were in Central-Eastern Kenya in 2013. Kiambu County had 46,656 PLHIV with 42,400 (91%) adults and 4,200(9%) children (1-14yrs). Amref Health Africa in Kenya, supported through USAID-APHIAplus KAMILI project, initiated two food banks to respond to poor nutritional status of the HIV infected children. Quality Improvement Teams were used to facilitate food-banking initiatives. The study aimed at assessing and demonstrating roles of community food-banking in improving nutrition status of HIV-infected children in food insecure regions. A pre and post-test study lasting 12 months (Oct 2013 to September 2014) conducted in Kiambu County, Kenya covering 103 HIV infected children. Two assessments were conducted before and after the food banking initiative and results compared. Child Status Index (CSI) and the Middle Upper Arm Circumference (MUAC) tools were used in data collection at households. Paired T-test and Wilcoxon test were applied for analysing MUAC and CSI scores respectively using the SPSS. There was a significant improvement in the children's nutrition status from a rating of 'bad' in CSI Median (IQR) score 2(2-1) before food banking to a rating of 'fair' in CSI Median (IQR) score 3(4-3) after food banking intervention (p=banking (p=banking is a community-based nutritional intervention that can address factors of food access, affordability and availability. Food banking is a sustainable way to contribute to quality nutrition and reduced related deaths among HIV infected children.
