Body donor programs need to balance ethical concerns and educational needs. Among donor programs in the US, there is variability in the amount of donor personal information that is provided to medical students. This study assesses this variability and investigates the reasons for the variability among donor programs. Telephone interviews and email surveys were used to collect information concerning the provision and use of donor personal information with medical students. One hundred fifty-one donor programs in the US were contacted via email or telephone interview or both. Fifty-three donor programs responded to the survey or participated in the telephone interview. The survey results show variation, not only in the amount of donor personal information provided to medical students, but also in the attitudes and beliefs of the donor program personnel concerning donor personal information. This research documents the variability of the educational use of donor personal information. It is hoped that this description of the various approaches to using donor information will encourage the ethical use of donor information within the context of medical education. Clin.

The safety of blood for transfusion depends, in part, on the reliability of the health history given by volunteer blood donors. To improve reliability, a pilot study evaluated the use of an interactive computer-based audiovisual donor interviewing system at a typical midwestern blood center in the United States. An interactive video screening system was tested in a community donor center environment on 395 volunteer blood donors. Of the donors using the system, 277 completed surveys regarding their acceptance of and opinions about the system. The study showed that an interactive computer-based audiovisual donor screening system was an effective means of conducting the donor health history. The majority of donors found the system understandable and favored the system over a face-to-face interview. Further, most donors indicated that they would be more likely to return if they were to be screened by such a system. Interactive computer-based audiovisual blood donor screening is useful and well accepted by donors; it may prevent a majority of errors and accidents that are reportable to the FDA; and it may contribute to increased safety and availability of the blood supply.

Recruitment and retention of first-time and repeat donors is essential to maintain a stable blood supply. Recent evidence has shown that promoting internal motivation may be an effective strategy to enhance donation behavior. We tested the efficacy of an in-person motivational interview at increasing internal motivation and intention to donate. A sample of 219 donors and nondonors (69.4% female; mean ± SD age, 19.2 ± 1.1 years; 52.1% nondonors) were randomly assigned to either a motivational or a knowledge interview. Immediately before and after the interview participants completed a measure of donation intention and the Blood Donor Identity Survey, which is a multidimensional measure of donor motivation. A latent profile analysis revealed three distinct latent classes, which were identified as low internal motivation, mid internal motivation, and high internal motivation. Comparison of change in latent class from pre- to postinterview revealed that a higher proportion of participants in the motivational interview group moved to a more internally motivated class compared to the knowledge interview group (i.e., 34% vs. 4%, respectively). Further, relative to the knowledge interview group, participants in the motivational interview group reported greater increases in intention to donate. A brief motivational interview may enhance donation intention and intrinsic motivation among both experienced donors and nondonors alike. © 2017 AABB.

Absence or presence? Complexities in the donor narratives of single mothers using sperm donation.

How do single mothers who have conceived a child via anonymous or identity-release sperm donation represent the donor? While the majority of mothers described their anonymous and identity-release donors as symbolically significant to their families, others were more likely to emphasize that their lack of information limited their thoughts about him. There is limited understanding of the factors that impact upon how single mothers represent the donor, and whether or not they are determined by specific donor programmes (anonymous or identity-release). Qualitative interviews were conducted with 46 women who had treatment at a UK licensed fertility clinic during the years 2003-2009. Twenty mothers (43%) had used an anonymous donor, and 26 (57%) had used an identity-release donor. Among the 46 mothers interviewed, all had at least one child conceived via donor insemination who was between the ages of 4 and 9 years. Mothers were heterosexual and were currently without a live-in and/or long-term partner. Interview data were analysed qualitatively according to the principles of thematic analysis. Findings indicated marked diversity in single mothers' representations of the donor. Most (n = 27) mothers talked about the donor as symbolically significant to family life and were likely to describe the donor as (i) a gift-giver, (ii) a gene-giver and (iii) a potential partner. Others (n = 16) talked about the donor as (i) unknown, (ii) part of a process and (iii) out of sight and out of mind. There were mothers with anonymous and identity-release donors in each group. Several mothers explained that their feelings about the donor had changed over time. All mothers conceived at a licensed fertility clinic in the UK. Findings are limited to individuals willing and able to take part in research on donor conception. The study offers greater insight into the factors influencing the donor narratives produced in single-mother families. It has implications for the counselling and treatment of single women seeking fertility treatment with donor gametes in both anonymous and identity-release programmes. Given that the number of clinics offering identity-release programmes worldwide seems to be increasing, the finding that single women may have varying preferences with regard to donor type, and varying interest levels with regard to donor information, is important. It is recommended that clinicians and other fertility clinic staff guard against making assumptions about such preferences and any thoughts and feelings about the donor or donor information on the basis of marital status.

Origins and originators: lesbian couples negotiating parental identities and sperm donor conception.

PubMed

Nordqvist, Petra

2012-01-01

Donor conception challenges conventional kinship idioms: the involvement of a gamete donor culturally raises questions about parentage and also the meaning of genetic heritage. Although there is now a growing body of literature exploring how people resorting to donor conception negotiate kinship and connectedness, this predominantly focuses on heterosexual couples. Little is yet known about how lesbian couples navigate these processes. This paper builds on a qualitative interview study comprising 25 lesbian couples in England and Wales with experiences of pursuing donor conception in the context of their couple relationship to explore how these couples negotiate the contribution of the donor. It explores how couples negotiate meanings of parenthood, genetic origins and the bodily process of conception. The paper argues that lesbian couples negotiate parental identities, biogenetic relationships and also the meaning of conception by disassembling and reassembling the meaning of kinship, parenthood, creation, origin and originator. Findings suggest that lesbian couples weave together old and new understandings of relatedness in complex patterns and that this enables them to assert authority as parents.

Although concerns have historically been raised about the influence of external donors on health policy process in recipient countries, remarkably few studies have investigated perspectives and experiences of domestic policymakers and advisers. This study examines donor influence at different stages of the health policy process (priority setting, policy formulation, policy implementation and monitoring and evaluation) in two aid-dependent LMICs, Cambodia and Pakistan. It identifies mechanisms through which asymmetries in influence between donors and domestic policy actors emerge. We conducted 24 key informant interviews-14 in Pakistan and 10 in Cambodia-with high-level decision-makers who inform or authorize health priority setting, allocate resources and/or are responsible for policy implementation, identifying three routes of influence: financial resources, technical expertise and indirect financial and political incentives. We used both inductive and deductive approaches to analyse the data. Our findings indicate that different routes of influence emerged depending on the stage of the policy process. Control of financial resources was the most commonly identified route by which donors influenced priority setting and policy implementation. Greater (perceived) technical expertise played an important role in donor influence at the policy formulation stage. Donors' power in influencing decisions, particularly during the final (monitoring and evaluation) stage of the policy process, was mediated by their ability to control indirect financial and political incentives as well as direct control of financial resources. This study thus helps unpack the nuances of donor influence over health policymaking in these settings, and can potentially indicate areas that require attention to increase the ownership of domestic actors of their countries' health policy processes. © The Author(s) 2017.

This article is part of a study to gain insight into the decision-making process by looking at the views of the relatives of potential brain dead donors. Alongside a literature review, focus interviews were held with healthcare professionals about their role in the request and decision-making process when post-mortal donation is at stake. This article describes the perspectives of the relatives. A content-analysis of 22 semi-structured in-depth interviews with relatives involved in an organ donation decision. Three themes were identified: 'conditions', 'ethical considerations' and 'look back'. Conditions were: 'sense of urgency', 'incompetence to decide' and 'agreement between relatives'. Ethical considerations result in a dilemma for non-donor families: aiding people or protecting the deceased's body, especially when they do not know his/her preference. Donor families respect the deceased's last will, generally confirmed in the National Donor Register. Looking back, the majority of non-donor families resolved their dilemma by justifying their decision with external arguments (lack of time, information etc.). Some non-donor families would like to be supported during decision-making. The discrepancy between general willingness to donate and the actual refusal of a donation request can be explained by multiple factors, with a cumulative effect. Firstly, half of the participants (most non-donor families) stated that they felt that they were not competent to decide in such a crisis and they seem to struggle with utilitarian considerations against their wish to protect the body. Secondly, non-donor families refused telling that they did not know the deceased's wishes or contesting posthumous autonomy of the eligible. Thirdly, the findings emphasise the importance of Donor Registration, because it seems to prevent dilemmas in decision-making, at least for donor families. Discrepancies between willingness to consent to donate and refusal at the bedside can be attributed to an unresolved dilemma: aiding people or protect the body of the deceased. Non-donor families felt incompetent to decide. They refused consent for donation, since their deceased had not given any directive. When ethical considerations do not lead to an unambiguous answer, situational factors were pivotal. Relatives of unregistered eligible donors are more prone to unstable decisions. To overcome ambivalence, coaching during decision-making is worth investigation.

Fear, fascination and the sperm donor as 'abjection' in interviews with heterosexual recipients of donor insemination.

PubMed

Burr, Jennifer

2009-07-01

The background to this article is the medical regulation of sperm donation in the UK and the recent policy change so that children born from sperm, eggs or embryos donated after April 2005 have the right to know their donor's identity. I draw upon data from interviews with ten women and seven joint interviews with couples who received donor insemination from an anonymous sperm donor and were the parents of donor insemination children. I explore the symbolic presence of the donor and his potential to disrupt social and physical boundaries using the theoretical conceptions of boundaries and pollution as articulated by Mary Douglas and Julia Kristeva. I present data to argue that the anonymous donor manifests in various figures; the shadowy and ambiguous figure of 'another man'; the intelligent medical student; the donor as a family man, with children of his own who wants to help infertile men father children. In addition participants perceive the donor's physical characteristics, but also see their husband's physical characteristics, in their children. In conclusion I argue that anonymisation preserves features of conventional family life, maintains the idea of exclusivity within the heterosexual relationship and affirms the legal father's insecurity about his infertility.

Multiple meanings of "gift" and its value for organ donation.

PubMed

Shaw, Rhonda M; Webb, Robert

2015-05-01

The "gift of life" metaphor is used to promote organ donation where commercialization is prohibited. In this article, we explore how multiple parties involved in organ transfer procedures think of gift terminology by drawing on interview data with transplantation specialists, organ transplant recipients, living directed donors and living nondirected donors. The interviews took place across New Zealand between October 2008 and May 2012, in participants' homes and hospital workplaces. The interviews were transcribed verbatim, coded manually, and thematically analyzed. Although gift language is often viewed as clear-cut, the gift trope has multiple meanings for different constituent and cultural groups, ranging from positive descriptors to obscuring and romanticizing the complexities of transplantation processes. To account for these multiple perspectives, we suggest new ethical models to capture the nuanced phenomenon of organ transfer in ways that recognize the full range of donation and reception experiences. © The Author(s) 2014.

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

To evaluate the effectiveness of blood donor selection, this study reports risk profiles of donors with transfusion-transmissible infections as obtained by ongoing surveillance, 1995 through 2003, in the Netherlands. A surveillance program was installed to monitor risk profiles among new and repeat donors infected with human immunodeficiency virus (HIV), hepatitis C virus (HCV), hepatitis B virus (HBV), or human T-lymphotropic virus (HTLV), or positive for the presence of syphilis antibodies. At posttest counseling, a physician interviewed donors to clarify possible sources of infection. A total of 167 repeat donors and 404 new donors were interviewed: 33 with HIV, 123 with HCV, 279 with HBV, 21 with HTLV, and 112 with syphilis antibodies. Most HBV, HCV, and HTLV infections were among new donors (80, 85, and 67%), whereas most HIV infections were among repeat donors (79%). Nearly 25 percent of the donors did not report factors at screening that would have deferred them from donating blood. At posttest interviews, new donors with HCV often reported injecting drug use (19%). Repeat donors with HIV often reported male-to-male sex (8/26, 31%). A significant level of deferrable behavioral risks was found among donors with confirmed transfusion-transmissible infections that persist despite current donor selection. Reporting such behavior at initial donor selection would have eliminated a substantial part of the infections found. This study argues against relaxing the existing donor deferral of persons practicing male-to-male sex, given their significant proportion of HIV infections among repeat donors. Systematic surveillance of risk factors among infected blood donors provides ongoing information about the effectivity of donor selection and is recommended to evaluate and optimize blood policies.

Children's thoughts and feelings about their donor and security of attachment to their solo mothers in middle childhood.

What is the relationship between children's thoughts and feelings about their donor and their security of attachment to their solo mothers in middle childhood? Children with higher levels of secure-autonomous attachment to their mothers were more likely to have positive perceptions of the donor, and those with higher levels of insecure-disorganized attachment to their mothers were more likely to perceive him negatively. There is limited understanding of the factors that contribute to children's thoughts and feelings about their donor in solo mother families. In adolescence, an association was found between adolescents' curiosity about donor conception and their security of attachment to their mothers. 19 children were administered the Friends and Family Interview and Donor Conception Interview between December 2015 and March 2016 as part of the second phase of a longitudinal, multi-method, multi-informant study of solo mother families. All children were aged between 7 and 13 years and had been conceived by donor insemination to solo mothers. Interviews were conducted in participants' homes. The Friends and Family Interview was rated according to a standardized coding scheme designed to measure security of attachment in terms of secure-autonomous, insecure-dismissing, insecure-preoccupied and insecure-disorganized attachment patterns. Quantitative analyses of the Donor Conception Interview yielded two factors: interest in the donor and perceptions of the donor. Qualitative analyses of the Donor Conception Interview were conducted using qualitative content analysis and thematic analysis. Statistically significant associations were found between the perception of the donor scale and the secure-autonomous and insecure-disorganized attachment ratings. Children with higher levels of secure-autonomous attachment to their mothers were more likely to have positive perceptions of the donor (r = 0.549, P = 0.015), and those with higher levels of insecure-disorganized attachment to their mothers were more likely to perceive him negatively (r = -0.632, P = 0.004). Children's narratives about the donor depicted him as a stranger (n = 8), a biological father (n = 4), a social parent (n = 3), or in ambivalent terms (n = 4). Findings are limited by the wide age range of children within a small overall sample size. Participants were those willing and able to take part in research on donor conception families. The statistical significance of correlation coefficients was not corrected for multiple comparisons. Findings highlight the importance of situating children's ideas about the donor within family contexts. It is recommended that those working with donor conception families consider this when advising parents about whether, what and how to tell children about donor conception.

Embryo donation and understanding of kinship: the impact of law and policy.

What is the impact of law and policy upon the experience of embryo donation for reproductive use? Access to, and experience of, embryo donation are influenced by a number of external factors including laws that impose embryo storage limits, those that frame counselling and approval requirements and allow for, or mandate, donor identity disclosure. To date only three qualitative studies in Australia and New Zealand have been completed on the experience of embryo donation for reproductive purposes, each with a small cohort of interviewees and divergent findings. Embryo donors, recipients, and would-be donors were interviewed between July 2010 and July 2012, with three additional interviews between September 2015 and September 2016, on their experiences of embryo donation. The sampling protocol had the advantage of addressing donation practices across multiple clinical sites under distinct legal frameworks. Participants were recruited from five Australian jurisdictions and across 11 clinical sites. Twenty-six participants were interviewed, comprising: 11 people who had donated embryos for the reproductive use of others (nine individuals and one couple), six recipients of donated embryos (four individuals and one couple) and nine individuals who had attempted to donate, or had a strong desire to donate, but had been prevented from doing so. In total, participants reported on 15 completed donation experiences; of which nine had resulted in offspring to the knowledge of the donor. Donors positively desired donation and did not find the decision difficult. Neither donors nor recipients saw the donation process as akin to adoption . The process and practice of donation varied considerably across different jurisdictions and clinical sites. Because the pool of donors and recipients is small, caution must be exercised over drawing general conclusions. Saturation was not reached on themes of counselling models and future contact. The differences between our findings and those of a previous study are attributable to varied legal and counselling regimes. Therefore, law and policy governing embryo storage limits, counselling protocols and identity disclosure shape the donation experience and how it is described.

The present study provides an in-depth examination of the messages used by organ procurement coordinators (OPCs) in shaping familial requests for organ donation. OPCs (N = 102), recruited from a national sample of 16 organ procurement organizations, participated in a structured interview designed to uncover the communication strategies used in obtaining familial consent for donation. Analysis of interviews indicates OPCs' messages cover 4 domain areas. Specifically, OPCs report use of messages intended to (a) provide education, (b) discuss the benefits to donation, (c) learn about potential donor families, and (d) persuade families to engage in donation. Within the 4 domain areas, OPCs report use of 15 specific messages (e.g., "positively framing the donor," "social proof," "discuss the benefit of donation to grieving") in requesting consent. The present study provides a detailed examination of strategies and offers recommendations for using message strategies to explore the effectiveness of the consent process from the perspective of OPCs in approaching donor families.

Currently, in Brazil, 1.78% of the population area blood donors, a level lower than the ideal one that, according to WHO, should be between 3% and 5% of the population. Following this scenario, the current study has a general goal of identifying and analyzing the main critical factors of the process of blood donation in the city of Belo Horizonte, MG, under the perception of donors, potential donors and non donors. A qualitative research approach was conducted, through twenty-four semi-structured interviews. The results highlight the lack of information in the various stages of the blood donation system. During the stages of donor recruitment and awareness, communication actions convey to society incomplete information about the donation process, discouraging future actions of donation. On the other hand, a lack of appreciation of the donation experience and the construction of social values associated with the donor prevent the multiplication of social behaviors for donation. The results of this study, found from theoretical framework outlined in this study, highlight the causes or critical factors that impede changes in behavior, incremental or radical, proposed by social marketing.

Human milk banking.

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.

Obtaining corneal tissue for keratoplasty.

Cornea transplant is the most common tissue transplant in the world. In Spain, tissue donation activities depend upon transplant coordinator activities and the well-known Spanish model for organ and tissue donation. Tissue donor detection system and tissue donor evaluation is performed mainly by transplant coordinators using the Spanish model on donation. The evaluation of a potential tissue donor from detection until recovery is based on an exhaustive review of the medical and social history, physical examination, family interview to determine will of the deceased, and a laboratory screening test. Corneal acceptance criteria for transplantation have a wider spectrum than other tissues, as donors with active malignancies and infections are accepted for kearatoplasty in most tissue banks. Corneal evaluation during the whole process is performed to ensure the safety of the donor and the recipient, as well as an effective transplant. Last step before processing, corneal recovery, must be performed under standard operating procedures and in a correct environment. Copyright © 2016 Sociedad Española de Oftalmología.

We report the views of 33 women who were involved in an altruistic oocyte donation program about provisions under Canada's Assisted Human Reproduction Act 2004 to prohibit donor compensation and to establish a Personal Health Information Registry. The participants had been either donors of oocytes to a recipient known to them (15) or recipients of such donation (18) through services provided by a clinic in a large Canadian city, and they each participated in a semi-structured face-to-face or telephone interview. Among the 15 donor participants, seven were friends of the recipient, six were sisters, one was a niece of the recipient, and one donor donated twice, once to her sister and once to a friend. In eight cases the donor and recipient participated in interviews independently. At the time of interview, 11 of the 25 separate cases had resulted in a live birth and one in an ongoing pregnancy, so that "successful" and "unsuccessful" donations were equally represented among participants. While divergent views were reported among and between donors and recipients on an altruistic model versus a compensated model of donation, most participants largely endorsed the establishment of a personal health information registry.

We identified [1] demographic predictors of requesting donor identities, [2] information release timing and length, and [3] request motives. Just >35% of eligible DI adults requested their donor's identity. Adults ranged from 18-27 years, requesting at median age 18 years. More women than men requested. Proportionally fewer adults requested when they had heterosexual-couple parents, and proportionally more when they had one rather than two parents. In interviews, the common theme was wanting to know more about the donor, especially about shared characteristics. Most adults planned to contact their donor. More than 94% of adults had donors who were open to contact; adults expressed modest expectations about this contact. In 2001, the first adults became eligible to obtain their open-identity sperm donor's information. Ten years of identity requests at one program indicates that information about one's donor is important to a significant proportion of these DI adults. Most requested their donor's identity soon after becoming eligible, suggesting some urgency to wanting the information. Interview data highlighted the role of donor information in helping adults better understand themselves and their ancestry. Findings hold important implications for practice and policy.

2006-02-01

Although only 6% of the eligible United Kingdom population regularly donate blood, reasons for low donation rates remain poorly understood. In a grounded theory investigation, blood donors (n = 23) and non-donors (n = 27) completed a questionnaire that included 15 open-ended items. Semi-structured interviews were conducted with sub-samples of donors (n = 5) and non-donors (n = 7). Analysis of open-ended responses and interview transcripts identified five themes. Three themes, namely pro-social views, helping behaviour and awareness had similar relevance for donors and non-donors. Two themes, anxiety and practical difficulties, were used by non-donors to account for non-donation despite intentions to donate. Although non-donors' anxieties may be difficult to overcome, perceived practical difficulties provide scope for intervention. The removal of perceived barriers to donation offers one way of increasing donation rates.

Swedish legislation requires that sperm donors are identifiable to offspring. In Denmark sperm donors remain anonymous. The aim of this study was to examine sperm donation in Sweden by identifying socio-demographic backgrounds, motivations and attitudes among donors and to describe options and plans of sperm recipients. Furthermore, the willingness of Swedish health care providers to assist in treatment abroad, where sperm from an anonymous donor were to be used, was assessed. The extent of travelling to Denmark for reproductive purposes was also examined. Thirty Swedish sperm donors completed a questionnaire and were interviewed about their backgrounds, motivations and attitudes. Thirty couples where the infertility workup had shown azoospermia were interviewed about their options for achieving parenthood. The willingness to assist in fertility treatment abroad and the extent of reproductive cross border travelling were assessed by interviewing health care providers and by contacting Danish clinics. Almost all donors were Caucasian. The main motivation for sperm donors was to help others. Owing to shortage of sperm donors many Caucasian recipients intended to have treatment abroad. For most non-Caucasian recipients sperm from a donor of appropriate ethnicity were not available in Sweden. Whether the sperm donor was anonymous or identifiable was not of major importance to most sperm recipients. Health care providers expressed unanimous willingness to assist in treatment with sperm from an anonymous donor. Our inquiry indicated that more than 250 Swedish sperm recipients travel to Denmark annually. Identifiable sperm donors are driven by altruistic motives, but shortage of sperm donors leads to reproductive travelling. Recruitment strategies to increase the number of sperm donors in Sweden are therefore warranted.

Predonation screening questions about sexual risk factors should provide an extra layer of safety from recently acquired infections that may be too early to be detected by testing. Donors are required to read a definition of sex as it applies to predonation screening questions each time they come to donate, but how well donors apply such definitions has not been evaluated. We aimed to determine how donors define sex when answering screening questions. In total, 1297 whole blood donors were asked in a private interview to select from a list of sexual activities which ones they believed were being asked about in sexual background questions. Donors' definitions were coded as under-inclusive, correct or over-inclusive in relation to the blood services' definition. Qualitative interviews were carried out with 21 donors to understand reasoning behind definitions. Most donors had an over-inclusive definition (58.7%) or the correct definition (31.9%). Of the 9.4% of donors who had an under-inclusive definition, 95% included both vaginal and anal sex, but not oral sex. About 9% in each group were first-time donors (P > 0.05) who had never read the definition. The qualitative interviews indicated that donors reason their definition based on their own concept of transmissible disease risk. Donors apply a range of definitions of sex when answering questions about their sexual background. This may be due to different concepts of risk activities, and required reading of the definition has little impact.

Patients' Main Concerns About Having a Sibling Stem Cell Donor - A Grounded Theory Study.

PubMed

Kisch, Annika M; Forsberg, Anna

2018-01-01

There is limited knowledge about the perspective of patients undergoing allogeneic haematopoietic stem cell transplantation (HSCT) about having a sibling as donor. It is essential to understand the main concerns of stem cell recipients in order to enable nurses to provide person-centred care. The study aim was to explore patients' main concerns about having a sibling stem cell donor and how the patients handle them, from immediately before until one year after transplantation. Twenty-eight interviews were performed prospectively during one year with ten adult sibling stem cell recipients with a mean age of 52 years (range 19-68 years). The interviews were analyzed by the Grounded Theory method. The core category Recompensation summarises the process in the generated grounded theory including the three main categories; Invest , Compensate and Celebrate . Recompensation is defined as a lasting compensation given by the recipient to the sibling donor for the loss or harm suffered or effort made. The sense of having to reward, protect, appreciate, maintain peace and work on the relationship with the sibling donor at the same time as having to accept a serious illness, cope with their situation and promote their own recovery is strenuous for the recipients. The main concern for stem cell recipients during their first post-transplant year is to recompensate the sibling donor by investing, compensating and celebrating her/him. Although there is a positive aspect of recompensation, it can also imply pressure and guilt.

Family Communication about Donor Conception: A Qualitative Study with Lesbian Parents.

2016-03-01

In this qualitative study of 10 lesbian couples who built their families through anonymous donor conception, we explore how lesbian parents experience communication about the donor conception within the family. While for these families "disclosure" of donor conception is often seen as evident, the way parents and children discuss this subject and how this is experienced by the parents themselves has not received much research attention. To meet this gap in the literature, in-depth interviews with lesbian couples were conducted. An Interpretative Phenomenological Analysis showed that this family communication process can be understood within the broader relational context of parent-child relationships. Even though parents handled this family communication in many different ways, these were all inspired by the same motives: acting in the child's best interest and-on a more implicit level-maintaining good relations within the family. Furthermore, parents left the initiative for talking about the DC mostly to the child. Overall, parents aimed at constructing a donor conception narrative that they considered acceptable for both the children and themselves. They used different strategies, such as gradual disclosure, limiting the meaning of the donor, and justifying the donor conception. Building an acceptable donor conception narrative was sometimes challenged by influences from the social environment. In the discussion, we relate this qualitative systemic study to the broader issues of selective disclosure and bidirectionality within families. © 2014 Family Process Institute.

Activity in renal transplantation at our center continues to grow due to the gradual increase in living donor kidney transplantations (LDKT). Our objective was to describe the generation process of living donation in our area of influence including two provinces and 18 chronic kidney disease (CKD) treatment units in particular the origin of paired donor/recipients and information channels. We included all actual and discarded potential donors from 2005 to 2009. History and telephone interviews provided a description of the cases, sources and process information. Among 95 potential pairs we performed 44 LDKT during this period. The recipients were predialysis (38%), on dialysis (54%), or after prior transplantation (8%). Among the 10 dialysis centers, the referral rate ranged between 0 and 8.6 pairs per 100 patients. We contacted 78 (83%) donors for an interview, among whom 53% first learned of LDKT when the recipient already had advanced CKD at predialysis or dialysis stages. Television was the main means of this first knowledge (38%), followed by the health care staff. LDKT was not primarily a treatment option offered by the nephrologist for 65% of subjects; however, the nephrologists were the major reference sources followed by the Internet and transplant coordinators. The majority of donations are initiated before the recipient is on dialysis, but eventuates predialysis in only 38% of cases. The possibility of being referred seems to be influenced by the recipient's treatment center. We need a more proactive role of nephrologists to offer this therapeutic option. This study identified the importance of public information to identify targets and design strategies to disseminate quality information on LDKT. Copyright © 2011 Elsevier Inc. All rights reserved.

While donation after circulatory death (DCD) has expanded options for organ donation, many who wish to donate are still unable to do so. We conducted face-to-face interviews with family members (N = 15) who had direct experience with unsuccessful DCD and 5 focus groups with professionals involved in the donation process. We used qualitative content analysis to characterize the harms of nondonation as perceived by participants. Participants reported a broad spectrum of harms affecting organ recipients, donors, and donor families. Harms included waste of precious life-giving organs and hospital resources, inability to honor the donor's memory and character, and impaired ability for families to make sense of tragedy and cope with loss. Donor families empathized with the initial hope and ultimate despair of potential recipients who must continue their wait on the transplant list. Focus group members reinforced these findings and highlighted the struggle of families to navigate the uncertainty regarding the timing of death during the donation process. While families reported significant harm, many appreciated the donation attempt. These findings highlight the importance of organ donation to donor families and the difficult experiences associated with current processes that could inform development of alternative donation strategies. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

The present study explored the process of disclosure in gamete donation families in the UK. Interviews were conducted with 23 mothers and 15 fathers who had told their 7-year-old child about the nature of their conception. Twelve children were interviewed about what they understood and how they felt about their donor conception (DC). The majority of families had disclosed by the age of four and mothers were found to be the main disclosers. Although some parents expressed concerns about the disclosure, the majority did not experience difficulties. No child responded to disclosure in a negative way. Seven-year-old children showed little understanding of their DC, despite parents starting the process of disclosure before the age of four. In spite of mothers' concerns about disclosing DC to their children, children responded to disclosure in a neutral way and most parents did not find disclosure to be problematic.

Intensive Care to facilitate Organ Donation (ICOD) may help to increase the donor pool. We describe the Spanish experience with ICOD. Achieving Comprehensive Coordination in Organ Donation (ACCORD)-Spain consisted of an audit of the donation pathway from patients who died as a result of a devastating brain injury (possible donors) in 68 hospitals during November 1, 2014, to April 30, 2015. We focused on possible donors whose families were interviewed to discuss organ donation once intensive care with a therapeutic purpose was deemed futile and brain death (BD) was a likely outcome. Of the 1970 possible donors in ACCORD-Spain, in 257, the family was interviewed once the decision had been made not to intubate/ventilate (n = 105), with the patient under intubation/ventilation outside of the intensive care unit (n = 59), or with the patient intubated/ventilated within the intensive care unit (n = 93).Consent to ICOD was obtained in 174 cases. Consent was higher when the donor coordinator participated in the interview (odds ratio, 2.32; 95% confidence interval, 1.33-4.11; P = 0.003). One hundred thirty-one patients developed BD, of whom 117 transitioned to actual donation after BD. Of the 35 patients who did not develop BD, 2 transitioned to actual donation after circulatory death. Sixteen patients subject to ICOD were finally medically unsuitable organ donors.ICOD contributed to 24% of the 491 actual donors registered in ACCORD-Spain. Despite the complexity of the interview, the majority of families consented to ICOD. Estimating the probability of BD and assessing medical suitability are additional challenges of the practice. ICOD represents a clear opportunity to increase the donor pool and ensures organ donation is posed at every end-of-life care pathway.

Blood donor experiences both immediate adverse reactions (IAR) and delayed adverse reactions (DAR). With limited published data available on the incidence of DAR, a study was conducted to estimate incidence and profile of DAR through telephonic interview. Study was conducted over a 45-day period for consecutive volunteer whole blood donations at tertiary care hospital. Donors were divided into first-time, repeat and regular and were monitored for IAR. They were given written copy of post-donation advice. Donors were contacted telephonically three weeks post-donation and enquired about general wellbeing and specific DAR in accordance with a standard n international (International Society of Blood Transfusion) standard format. Donors participated in the study of which 1.6% donors experienced an IAR. Much larger number reported DAR (10.3% vs.1.6% p<0.0001). Further, DAR was presented as a variegated profile with bruise, painful arms and fatigue being the commonest. DARs were more common in females than males (25% vs. 10.3%, p<0.02). Localized DAR like bruise and painful arms were more common in younger donors (age <50 years) whereas systemic DAR like fatigue was common in older donors (>50 years). First time (12.3%) and repeat donors (13.5%) had similar frequency of DAR but were lower among regular donors (6.7%). DARs are more common than IAR and are of different profile. Post-donation interview has provided an insight into donor experiences and can be used as a valuable tool in donor hemovigilance. Copyright © 2016 Elsevier Ltd. All rights reserved.

Recent changes to United States law now permit people living with HIV (PLWH) to donate organs to HIV-infected (HIV+) recipients under research protocols. PLWH may have unique motivations for and concerns about living donation and understanding them is critical to ensuring the integrity of this novel approach to organ transplantation. We conducted in-depth interviews with PLWH from an urban HIV clinic who had previously indicated their willingness to be a living donor. Interviews elicited information on their motivations, perceived benefits, and concerns regarding living donation. Codes were identified inductively and then organized into themes and subthemes. Two coders independently analyzed the interviews and reconciled differences in coding by consensus. Thematic saturation was reached after 20 interviews. Motivations for living donation among PLWH included an altruistic desire to help others as well as HIV-specific motivations including solidarity with potential recipients and a desire to overcome HIV-related stigma. Perceived benefits of living donation included gratification from saving or improving the recipient's life and conferring a sense of normalcy for the HIV+ donor. Concerns about donation included the possibility of a prolonged recovery period, organ failure, and transmission of another strain of the virus to the recipients. PLWH had unique motivations, perceived benefits, and concerns about living donation in addition to those previously identified in the general population. These unique factors should be addressed in research protocols, informed consent processes, and the education and training of independent living donor advocates so that these endeavors are ethically sound.

Based on the hypothesis that self-determined motivation is associated with an increased likelihood of future behavior, the present study examined the ability of a motivational interview to promote internal motivation for giving blood and future donation attempts. A sample of 484 recent whole-blood and double red blood cell donors (62.4% female; age = 30.2 ± 11.8 years) were randomly assigned to either a telephone-delivered motivational interview or a control call approximately 6 weeks after donating. Several weeks before the call and again 1 week after the call, participants completed the Blood Donor Identity Survey, a multidimensional measure of donor motivation, to derive indices of amotivation, external motivation, and internal motivation to give blood. Repeat donation attempts were tracked using blood center records. Relative to controls, participants in the motivational interview group showed a shift toward more self-determined motivation, as indicated by significant decreases in amotivation (p = 0.01) and significant increases in external (p = 0.009) and internal (p = 0.002) motivation. Furthermore, those with initially high levels of autonomous motivation were more likely to make a donation attempt in the subsequent year if they completed the motivational interview (71.1%) versus the control call (55.1%). Motivational interviewing is a potentially useful strategy to enhance retention of existing blood donors, particularly among those who express a greater sense of internal motivation for giving. © 2017 AABB.

The low rate of consent by next of kin of donor-eligible patients is a major limiting factor in organ transplant. Educating health care professionals about their role may lead to measurable improvements in the process. Our aim was to describe the developmental steps of a communication skills training program for health care professionals using standardized patients and to evaluate the results. We developed a rubric and 5 cases for standardized family interviews. The 20 participants interviewed standardized families at the beginning and at the end of the training course, with interviews followed by debriefing sessions. Participants also provided feedback before and after the course. The performance of each participant was assessed by his or her peers using the rubric. We calculated the generalizability coefficient to measure the reliability of the rubric and used the Wilcoxon signed rank test to compare achievement among participants. Statistical analyses were performed with SPSS software (SPSS: An IBM Company, version 17.0, IBM Corporation, Armonk, NY, USA). All participants received higher scores in their second interview, including novice participants who expressed great discomfort during their first interview. The participants rated the scenarios and the standardized patients as very representative of real-life situations, with feedback forms showing that the interviews, the video recording sessions, and the debriefing sessions contributed to their learning. Our program was designed to meet the current expectations and implications in the field of donor consent from next of kin. Results showed that our training program developed using standardized patient methodology was effective in obtaining the communication skills needed for family interviews during the consent process. The rubric developed during the study was a valid and reliable assessment tool that could be used in further educational activities. The participants showed significant improvements in communication skills.

Objective: to identify experiences and feelings on the organ donation process, from the perspective of a relative of an organ donor in a transplant unit. Method: this was exploratory research using a qualitative approach, performed with seven family members of different organ donors, selected by a lottery. Sociodemographic data and the experiences regarding the donation process were collected through semi-structured interviews. The language material was transcribed and submitted to content analysis. Results: poor sensitivity of the medical staff communicating the relative's brain death - the potential donor - and the lack of socio-emotional support prior to the situation experienced by the family was highlighted by participants. Conclusions: the study identified the need to provide social-emotional support for families facing the experience of the organ donation process. From these findings, other care and management practices in health must be discussed to impact the strengthening of the family ties, post-donation, as well as the organ procurement indexes.

STUDY QUESTION What is the impact of law and policy upon the experience of embryo donation for reproductive use? SUMMARY ANSWER Access to, and experience of, embryo donation are influenced by a number of external factors including laws that impose embryo storage limits, those that frame counselling and approval requirements and allow for, or mandate, donor identity disclosure. WHAT IS KNOWN ALREADY To date only three qualitative studies in Australia and New Zealand have been completed on the experience of embryo donation for reproductive purposes, each with a small cohort of interviewees and divergent findings. STUDY DESIGN, SIZE, DURATION Embryo donors, recipients, and would-be donors were interviewed between July 2010 and July 2012, with three additional interviews between September 2015 and September 2016, on their experiences of embryo donation. The sampling protocol had the advantage of addressing donation practices across multiple clinical sites under distinct legal frameworks. PARTICIPANTS/MATERIALS, SETTINGS, METHODS Participants were recruited from five Australian jurisdictions and across 11 clinical sites. Twenty-six participants were interviewed, comprising: 11 people who had donated embryos for the reproductive use of others (nine individuals and one couple), six recipients of donated embryos (four individuals and one couple) and nine individuals who had attempted to donate, or had a strong desire to donate, but had been prevented from doing so. In total, participants reported on 15 completed donation experiences; of which nine had resulted in offspring to the knowledge of the donor. MAIN RESULTS AND THE ROLE OF CHANCE Donors positively desired donation and did not find the decision difficult. Neither donors nor recipients saw the donation process as akin to adoption . The process and practice of donation varied considerably across different jurisdictions and clinical sites. LIMITATIONS, REASONS FOR CAUTION Because the pool of donors and recipients is small, caution must be exercised over drawing general conclusions. Saturation was not reached on themes of counselling models and future contact. WIDER IMPLICATIONS OF THE FINDINGS The differences between our findings and those of a previous study are attributable to varied legal and counselling regimes. Therefore, law and policy governing embryo storage limits, counselling protocols and identity disclosure shape the donation experience and how it is described. STUDY FUNDING/COMPETING INTEREST(S) This research was supported by Discovery Project Grants DP 0986213 and 15010157 from the Australian Research Council and additional funding from UTS: Law. There are no conflicts of interest to declare. TRIAL REGISTRATION NUMBER Not applicable. PMID:27927845

Living kidney donation: considerations and decision-making.

2014-06-01

When possible, renal transplantation is the treatment of choice for patients with end-stage kidney disease. Technological developments in immunology have made it possible to perform kidney transplants between donors and recipients despite antibodies against the donor organ. This allows for a wider range of relationships between recipient and donor. We investigated experiences of, and reflections on, kidney donation among genetic and non-genetic living donors before first consultation at the transplant centre. The aim was to investigate early experiences in the process of becoming a living kidney donor (LKD). The study was conducted within a phenomenological-hermeneutic theoretical framework. Data were generated through semi-structured interviews with 18 potential donors. Data were interpreted and discussed in accordance with the Ricoeur's text interpretation theory on the three levels of naïve reading, structural analysis and critical interpretation and discussion. Two themes emerged: the decision-making process and dilemmas in decision-making. The study identifies that the decision about donation was made in relation to one's own life, family situation and in relation to the recipient-considerations that demonstrate that a range of dilemmas can occur during the decision-making process. The desire to help was prominent and was of significance in decision-making. The study provides insight and knowledge for the health care professionals to meet and involve donors' narratives in reflections about and modifications to clinical nursing practice. It is essential that health care professionals have an understanding and appreciation of the experiences and concerns among LKDs, and this can help in planning and providing individual nursing care and support to donors. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

Donor insemination: eugenic and feminist implications.

PubMed

Hanson, F A

2001-09-01

One concern regarding developments in genetics is that, when techniques such as genetic engineering become safe and affordable, people will use them for positive eugenics: to "improve" their offspring by enpowering them with exceptional qualities. Another is whether new reproductive technologies are being used to improve the condition of women or as the tools of a patriarchal system that appropriates female functions to itself and exploits women to further its own ends. Donor insemination is relevant to both of these issues. The degree to which people have used donor insemination in the past for positive eugenic purposes may give some insight into the likelihood of developing technologies being so used in the future. Donor insemination provides women with the opportunity to reproduce with only the most remote involvement of a man. To what degree do women take advantage of this to liberate themselves from male dominance? Through questionnaires and interviews, women who have used donor insemination disclosed their criteria for selecting sperm donors. The results are analyzed for the prevalence of positive eugenic criteria in the selection process and women's attitudes toward minimizing the male role in reproduction.

"I didn't have anything to decide, I wanted to help my kids" - An interview-based study of consent procedures for sampling human biological material for genetic research in rural Pakistan.

Individual, comprehensive, and written informed consent is broadly considered an ethical obligation in research involving the sampling of human material. In developing countries, however, local conditions, such as widespread illiteracy, low levels of education, and hierarchical social structures complicate compliance with these standards. As a result, researchers may modify the consent process to secure participation. To evaluate the ethical status of such modified consent strategies it is necessary to assess the extent to which local practices accord with the values underlying informed consent. Over a two-week period in April 2014 we conducted semi-structured interviews with researchers from a genetic research institute in rural Pakistan and families who had given blood samples for their research. Interviews with researchers focused on the institute's requirements for consent, and the researchers' strategies for and experiences with obtaining consent in the field. Interviews with donors focused on their motivation for donating samples, their experience of consent and donation, and what factors were central in their decisions to give consent. Researchers often reported modifications to consent procedures suited to the local context, standardly employing oral and elder consent, and tailoring information to the social education level of donor families. Central themes in donors' accounts of their decision to consent were the hope of getting something out of their participation and their remarkably high levels of trust in the researchers. Several donor accounts indicated a degree of confusion about participation and diagnosis, resulting in misconceived expectations of therapeutic benefits. We argue that while building and maintaining trusting relationships in research is important - not least in developing countries - strategies that serve this endeavor should be supplemented with efforts to ensure proper provision and understanding of relevant information, specifically about the nature of research and measures for individual consent and opt-out.

Families working it out: adolescents' views on communicating about donor-assisted conception.

2007-08-01

Prompted by legislation in Victoria, Australia, permitting gamete donors to seek identifying details of people conceived from their gametes, this research investigated the views of adolescents from the general population on how parents can best talk to their donor-conceived adolescent children about their conception. Qualitative interviews (six group discussions, n = two to six per group, and one individual interview) lasting c. 50 min with 25 secondary school students. Naïve adolescents had views largely consistent with those of donor-conceived adults, for example, urging parental honesty, adaptation to individual children, and family cohesion. They identified the social father as the parent while acknowledging the significance of genetic connection to the donor. A minority asserted a preference for non-disclosure; all said that, if disclosed, it should be by parents. This small study contributes to increasing understanding of communication within families about donor-assisted conception.

The aim of this study was to investigate from the perspectives of the donor parents of children with biliary atresia, the essence of family experiences during the period when waiting for a living donor liver transplant. Living donor liver transplantation is a new hope for children and families when the child suffers from biliary atresia. It is obvious, during the waiting period, for a family with a child undergoing living donor liver transplantation, that the process has a serious impact and there is a need for them to be well-prepared. A descriptive phenomenological design was used in this study. Nine donor parents from a medical centre in Taiwan participated in this study. The inclusion criteria were that the parent had a child with biliary atresia, that the child had received living donor liver transplantation over the last year and a half and that the parent was the living donor for child's liver transplantation. An open in-depth interview technique encouraged the parents to reflect on their experiences as the process raised their feelings to a conscious level. The data were analysed using the Colaizzi's approach. This study explores the essence of families undergoing the waiting period for living donor liver transplantation surgery from the point of view of the donating parents. Five themes emerged: (1) surgery as hope of rebirth, (2) negotiating the decision to have surgery, (3) the selection of the donor to achieve family welfare, (4) preparing and planning for the surgery and (5) worry over the impact of the surgery. The results demonstrate that the parents' experiences included a variety of domains: hope of rebirth, mental negotiation while deciding on surgery and choice of donor, coping with the preparation for surgery and the possible impact on the family of the surgery. The findings indicated that nursing professionals should provide family-centred care to assist the family with the steps needed to move toward surgery.

[Myths about organ donation on health personnel, potential recipients and relatives of potential donors in a peruvian hospital: a qualitative study].

To explore the myths regarding organ donation at a national hospital in Lambayeque, Peru during 2014. A qualitative-phenomenological study was performed using 24 unstructured in-depht interview of health personnel, potential recipients and relatives of potential donors. Sampling was intentional opinion-based, completed by theoretical saturation in each group. An interview guide was used, which was assessed by five experts, and data triangulation was performed. Twenty-three interviewees (95,8%) reported a favorable attitude towards organ donation. On their National Identification Document, thirteen (54,2%) had marked "no" for donation. The myths were: age or illness can preclude donation; that the recipient may experience the donor's behaviours and lives in it; brain death is undestood as the immobility of the body and a reversible state; religions do not accept organ donation because it affects physical integrity and resurrection; and that there are preferences on the organ donor waiting list and that organ trafficking taxes place. Myths explored in this study involved religious, socio-cultural, psychological and ethical misperceptions. The apparent lack of knowledge of the brain death diagnosis is the starting point of the donation process. Therefore, the presence of a hospital coordinator, the role of spiritual leaders and the correct information provided by media would be key parts to dispell these myths.

Female-partnered and single women's contact motivations and experiences with donor-linked families.

What are female-partnered and single mothers' motivations and experiences at one donor insemination (DI) program with regard to contacting other families who share the same sperm donor? By and large, women reported seeking contact to obtain (i) support for their children and/or themselves, and (ii) information about shared traits and medical problems, ultimately describing a range of contact experiences, both positive (e.g. special bond created) and negative (e.g. uncomfortable encounters). There is a growing phenomenon of donor insemination families-parents and/or offspring-seeking others who share their donor (i.e. are 'donor-linked'). There is limited understanding about parental motivations and experiences-especially in the presence of a second parent-due to the methodological constraints of previous quantitative studies. Semi-structured telephone interviews were conducted with 50 donor insemination mothers (14 single, 36 female-partnered). Participants were recruited by email invitation to parent members of a family-matching service at one donor insemination program in the USA. The criterion for inclusion was having matched to at least one donor-linked family. Among the 50 mothers interviewed, all had at least one child conceived via donor insemination, who was between ages 0 and 15 years at first contact. Families matched with a median of three donor-linked families (range 1-10). Interview data were analyzed through qualitative (i.e. thematic) analysis. Overarching themes emerged of seeking contact to obtain (i) support and (ii) information about children's shared physical and psychological traits. Some wanted to increase their child's family network, through adding a sibling, but more often as extended family. Data, from partnered parents especially, revealed the challenges of balancing the boundaries of family formed without the genetic link with the perceived benefits of exploring the child's donor origins. Interviews focused on openness and information-sharing were conducted with parents from one American donor insemination program. Findings are limited to individuals who were open enough to share their experiences and able to take the time to do so. As donor-linking services become established independently (e.g. donor insemination program registries) or by the government (e.g. Victoria, Australia's Voluntary Register), these findings provide evidence that linking services are valued by individuals affected by donor conception. Caution is warranted, however, in that some participants reported mismatched expectations, both across donor-linked families and within families (e.g. between partners), suggesting the need for information and guidance both during and after matching. Overall, the range and balance of reported positives and negatives indicate that donor-linking can provide individuals with support and donor origins information-which are particularly important when these are not available elsewhere.

Anonymous oocyte donation in the EU proceeds only after rigorous screening designed to ensure gamete safety. If anonymous donor gametes originating from outside EU territory are used by EU patients, donor testing must conform to the same standards as if gamete procurement had occurred in the EU. In Ireland, IVF recipients can be matched to anonymous donors in the Ukraine (a non-EU country). This investigation describes the evolution of anonymous oocyte donor screening methods during this period and associated results. Data were reviewed for all participants in an anonymous donor oocyte IVF programme from 2006 to 2009, when testing consistent with contemporary EU screening requirements was performed on all Ukrainian oocyte donors. HIV and hepatitis tests were aggregated from 314 anonymous oocyte donors and 265 recipients. The results included 5,524 Ukrainian women who were interviewed and 314 of these entered the programme (5.7% accession rate). Mean age of anonymous oocyte donors was 27.9 years; all had achieved at least one delivery. No case of hepatitis or HIV was detected at initial screening or at oocyte procurement. This is the first study of HIV and hepatitis incidence specifically among Ukrainian oocyte donors. We find anonymous oocyte donors to be a low-risk group, despite a high background HIV rate. Following full disclosure of the donation process, most Ukrainian women wishing to volunteer as anonymous oocyte donors do not participate. Current EU screening requirements appear adequate to maintain patient safety in the context of anonymous donor oocyte IVF.

Thorough psychosocial screening of donor candidates is required in order to minimize potential negative consequences and to strive for optimal safety within living donation programmes. We aimed to develop an evidence-based tool to standardize the psychosocial screening process. Key concepts of psychosocial screening were used to structure our tool: motivation and decision-making, personal resources, psychopathology, social resources, ethical and legal factors and information and risk processing. We (i) discussed how each item per concept could be measured, (ii) reviewed and rated available validated tools, (iii) where necessary developed new items, (iv) assessed content validity and (v) pilot-tested the new items. The resulting ELPAT living organ donor Psychosocial Assessment Tool (EPAT) consists of a selection of validated questionnaires (28 items in total), a semi-structured interview (43 questions) and a Red Flag Checklist. We outline optimal procedures and conditions for implementing this tool. The EPAT and user manual are available from the authors. Use of this tool will standardize the psychosocial screening procedure ensuring that no psychosocial issues are overlooked and ensure that comparable selection criteria are used and facilitate generation of comparable psychosocial data on living donor candidates. © 2017 Steunstichting ESOT.

It takes two to tango: information-sharing with offspring among heterosexual parents following identity-release sperm donation.

How do heterosexual parents reason about and experience information-sharing with offspring following identity-release sperm donation? Sharing information about using donor-conception with offspring is a complex process at several levels, with the parent's personal beliefs and the child's responses serving as driving or impeding forces for the information-sharing process. The overall view of disclosure in gamete donation has shifted from secrecy to openness, but there is still uncertainty among parents concerning how and when to tell the child about his/her genetic origin. Most research on donor-conceived families has focused on donation treatment under anonymous or known circumstances, and there is a lack of studies in settings with identity-release donations. A qualitative interview study among 30 parents following identity-release sperm donation treatment. Interviews were conducted from February 2014 to March 2015. The present study is part of the prospective longitudinal Swedish Study on Gamete Donation (SSGD), including all fertility clinics performing gamete donation in Sweden. A sample of participants in the SSGD, consisting of heterosexual parents with children aged 7-8 years following identity-release sperm donation, participated in individual semi-structured interviews. The analysis revealed one main theme: information-sharing is a process, with three subthemes; (i) the parent as process manager, (ii) the child as force or friction and (iii) being in the process. The first two subthemes were viewed as being linked together and their content served as driving or impeding forces in the information-sharing process. The fact that the study was performed within the context of the Swedish legislation on identity-release donation must be taken into consideration as regards transferability to other populations, as this may affect parents' reasoning concerning their information-sharing with the child. The present findings highlight the role of the donor-conceived child in the information-sharing process and may contribute to develop counselling that increases parents' confidence in handling children's reactions to information about their genetic origin.

Smith, André; Matthews, Ralph; Fiddler, Jay

2013-12-01

This study approaches the decision to donate blood as a dynamic process involving interplay between blood donors' personal motives, donors' social contexts, and the donor recruitment and retention activities of blood collection agencies. Data were gathered from four blood donation clinics using in-depth interviews with Canadian Blood Services employees, donors, and nondonors in 25 organizations participating in Life Link, a donor recruitment program that supports organizations to educate employees about the benefits of blood donation. Further data were obtained from ethnographic observations of blood collection and donor recruitment activities. Thematic analysis resulted in three umbrella themes: leveraging social networks, embedding the clinic in the community, and donating blood and social reciprocity. Donor recruitment activities at all four clinics enhanced awareness of blood donation in the workplace by using experienced donors to motivate their coworkers in making a first-time donation. Clinic employees reported varying success in improving awareness of blood donation in the broader community, in part because of varying employee engagement in community-wide activities and celebrations. Altruistic motives were mentioned by experienced donors, who also identified a desire to reciprocate to their community as another strong motive. This study contextualizes donor recruitment and retention as involving activities that tie blood donation to meaningful aspects of donors' social networks and community. The findings point to the need for further analyses of the institutional dimensions of blood donation to develop effective strategies beyond appeals to altruism. © 2013 American Association of Blood Banks.

Donor understandings of blood and the body in relation to more frequent donation.

Lynch, R; Cohn, S

2018-05-01

The INTERVAL trial aimed to find the optimum frequency of blood donation to enhance blood supplies and maintain donor health. This not only requires biological knowledge, but also an appreciation of donor perspectives, and how their experiences and beliefs might be central if any changes are ever to be made. To address this, trial participants were interviewed about their ideas of blood and the body in relation to their experiences of increased donation frequency. Thirty in depth face-to-face interviews conducted with blood donors participating in the trial. Three key themes emerged: ideas about how blood and iron reserves are replenished, and what people did to facilitate this; beliefs about physiological differences relating to age and gender; and practical issues that affected the experience of donation. Overall, participants interviewed welcomed more frequent donation, despite a range of pragmatic concerns. Despite some practical obstacles, increased donation frequency aligned with participant's ideas about bodily replenishment, the value of donation, and their identity as enduring blood donors. They therefore supported the idea of increasing frequency of donation, independently of the biomedical evidence from the trial itself. © 2018 International Society of Blood Transfusion.

The Core of Sibling Stem Cell Donation - A Grounded Theory Study.

Kisch, Annika M; Forsberg, Anna

There is a lack of theoretical framework supporting stem cell transplant nurses in their assessment, judgment and caring interventions of sibling stem cell donors. The purpose of this study was to explore sibling stem cell donors' main concerns and how they deal with them before and after donation. Ten healthy sibling donors, 5 men and 5 women, with a median age of 54 years were included in this study when they were due to donate stem cells to a brother or sister. Data were collected prospectively on three occasions (before the donation and three and twelve months after it) through in-depth interviews, which were recorded and transcribed verbatim for analysis by the Grounded Theory method according to Charmaz. This study describes the efforts of the ten donors to fulfil their duty as a sibling by doing what they considered necessary in order to help. Their efforts were summarised in a process wherein the grounded theory generated three main categories; Prepare, Promote and Preserve. A clear path of transition leading to fulfilment is evident, starting before the donation and continuing for one year afterwards. Being a sibling stem cell donor means doing what you have to do to fulfil your duty and if possible, saving the life of a seriously ill brother or sister. The relationship between the siblings is strengthened by the donation process. Sibling stem cell donation appears to be about fulfilment and the theoretical framework may support clinicians in their evaluation and support of donors.

In this study, we analysed stakeholder perceptions of the process of implementing the coordination of health-sector aid in Zambia, Africa. The aim of coordination of health aid is to increase the effectiveness of health systems and to ensure that donors comply with national priorities. With increases in the number of donors involved and resources available for health aid globally, the attention devoted to coordination worldwide has risen. While the theoretical basis of coordination has been relatively well-explored, less research has been carried out on the practicalities of how such coordination is to be implemented. In our study, we focused on potential differences between the views of the stakeholders, both government and donors, on the systems by which health aid is coordinated. A qualitative case study was conducted comprising interviews with government and donor stakeholders in the health sector, as well as document review and observations of meetings. Results suggested that stakeholders are generally satisfied with the implementation of health-sector aid coordination in Zambia. However, there were differences in perceptions of the level of coordination of plans and agreements, which can be attributed to difficulties in harmonizing and aligning organizational requirements with the Zambian health-sector plans. In order to achieve the aims of the Paris Declaration; to increase harmonization, alignment and ownership--resources from donors must be better coordinated in the health sector planning process. This requires careful consideration of contextual constraints surrounding each donor. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Having a sibling as donor: patients' experiences immediately before allogeneic hematopoietic stem cell transplantation.

Kisch, Annika; Bolmsjö, Ingrid; Lenhoff, Stig; Bengtsson, Mariette

2014-08-01

Allogeneic hematopoietic stem cell transplantation (HSCT) offers a potential cure for a variety of diseases but is also associated with significant risks. With HSCT the donor is either a relative, most often a sibling, or an unrelated registry donor. The aim was to explore patients' experiences, immediately before transplantation, regarding having a sibling as donor. Ten adult patients with sibling donors were interviewed before admission for HSCT. The interviews were digitally recorded, transcribed verbatim and subjected to qualitative content analysis. The main theme Being in no man's land is a metaphor for the patients' complex situation with its mixture of emotions and thoughts prior to transplantation. The three subthemes Trust in the sibling donor, Concern about others and Loss of control cover the various experiences. The patient's experiences are influenced by their personal situation and the quality of the relationship with the sibling donor. While patients feel secure in having a sibling donor, they are dependent for their survival on the cell donation and feel responsible for the donor's safety during donation. These emotions intensify the patients' sense of dependency and loss of control. In caring for HSCT patients the nurses should be aware of the complexity of the patients' situation and keep in mind that having a sibling donor might imply extra pressure, including a sense of responsibility. Caring for both patients and sibling donors optimally is a challenge, which needs further improvement and exploration. Copyright © 2014 Elsevier Ltd. All rights reserved.

Gamete donors' expectations and experiences of contact with their donor offspring

STUDY QUESTION What are the expectations and experiences of anonymous gamete donors about contact with their donor offspring? SUMMARY ANSWER Rather than consistently wanting to remain distant from their donor offspring, donors' expectations and experiences of contact with donor offspring ranged from none to a close personal relationship. WHAT IS KNOWN ALREADY Donor conception is part of assisted reproduction in many countries, but little is known about its continuing influence on gamete donors' lives. STUDY DESIGN, SIZE, DURATION A qualitative research model appropriate for understanding participants' views was employed; semi-structured interviews were conducted during January–March 2013. PARTICIPANTS/MATERIALS, SETTING, METHODS Before 1998, gamete donors in Victoria, Australia, were subject to evolving legislation that allowed them to remain anonymous or (from 1988) to consent to the release of identifying information. An opportunity to increase knowledge of donors' expectations and experiences of contact with their donor offspring recently arose in Victoria when a recommendation was made to introduce mandatory identification of donors on request from their donor offspring, with retrospective effect. Pre-1998 donors were invited through an advertising campaign to be interviewed about their views, experiences and expectations; 36 sperm donors and 6 egg donors participated. MAIN RESULTS AND THE ROLE OF CHANCE This research is unusual in achieving participation by donors who would not normally identify themselves to researchers or government inquiries. Qualitative thematic analysis revealed that most donors did not characterize themselves as parents of their donor offspring. Donors' expectations and experiences of contact with donor offspring ranged from none to a close personal relationship. LIMITATIONS, REASONS FOR CAUTION It is not possible to establish whether participants were representative of all pre-1998 donors. WIDER IMPLICATIONS OF THE FINDINGS Anonymous donors' needs and desires are not homogeneous; policy and practice should be sensitive and responsive to a wide range of circumstances and preferences. Decisions made to restrict or facilitate contact or the exchange of information have ramifications for donors as well as for donor-conceived people.

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

Background In Italy, the circulation of human immunodeficiency virus (HIV) has expanded to include population groups that do not perceive themselves to be “at risk” of HIV infection and who do not even consider undergoing HIV testing. The aim of this study was to describe the socio-demographic and behavioural characteristics, and perceived risk of HIV infection in a sample of blood donors who reported never having been tested for HIV. Materials and methods A questionnaire was administered to a sample of donors who called the Italian National AIDS/STI Help Line and reported never having been tested for HIV. Results The study sample consisted of 164 blood donors: 29.3% had given blood in the preceding 2 years. With regards to at-risk behaviours, 39.6% of the donors interviewed were heterosexuals who had sexual contacts with multiple partners, and 5.5% were men who had sex with multiple male partners. Sexual contacts with female sex workers were reported by 11.6% of first-time donors and 25.7% of repeat donors. Of the 164 donors interviewed, 125 (76.2%) said that the main reason that they had never been tested for HIV was that they did not consider themselves at risk. Among these, 56 (44.8%) reported that they would have sexual contacts with a sex worker, 52 (41.6%) reported that they would have sexual contacts with someone having more than one sexual partner, and 36 (28.8%) reported that they would have sexual contacts without using a condom. Discussion All the donors interviewed reported that they had never been tested for HIV despite the fact that they had been certainly been tested upon blood donation. These results show that some sexual behaviours may not be perceived as behaviours at risk for acquiring HIV infection. These findings suggest that not all blood donors are knowledgeable about HIV risk behaviours and that an explicit pre-donation questionnaire and effective counselling continue to be important for the selection of candidate donors.

The purpose of this study, based on the Theory of planned behavior, is to identify and ultimately better understand what determines the fidelity and the regularity of donors committed in plasmapheresis donation. This qualitative study is a primary stage to establish a classification of donors in a French socio-cultural context. For this reason, we have carried out a survey among 16 regular plasmapheresis donors, by way of semi-structured individual interviews at the Établissement français du sang - Brittany. The level of commitment of these regular donors is considered as a level of appropriation. If subjective norms have initially influenced their decision to donate blood, no specific motivation has been highlighted for them to donate plasma except a generally favourable attitude towards the voluntary donation process. The perception of control over their environment is a variable which played a decisive role in the donor's intention to give, with little cost associated to plasmapheresis donation and recourse to internal causal explanations. A better comprehension of the plasmapheresis donors' determinants should lead us to a more efficient awareness of new potential donors, thereby enhancing recruitment and retention. Due to the increasing need for plasma-derived products, this study's ultimate issue is closely correlated both with ethical and socio-economic aspects. Following which, after analysing the results, a certain number of recommendations will be made. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Objectives To examine health-related quality of life (HRQoL) among sibling pediatric hematopoietic stem cell donors from predonation through 1 year postdonation, to compare donor-reported HRQoL scores with proxy-reports by parents/guardians and those of healthy norms, and to identify predonation factors (including donor age) potentially associated with postdonation HRQoL, to better understand the physical and psychosocial effects of pediatric hematopoietic stem cell donation. Study design A random sample of 105 pediatric donors from US centers and a parent/guardian were interviewed by telephone predonation and 4 weeks and 1 year postdonation. The interview included sociodemo-graphic, psychosocial, and HRQoL items. A sample of healthy controls matched to donors by age, gender, and race/ethnicity was generated. Results Key findings included (1) approximately 20% of donors at each time point had very poor HRQoL; (2) child self-reported HRQoL was significantly lower than parent proxy-reported HRQoL at all 3 time points and significantly lower than that of norms at predonation and 4 weeks postdonation; and (3) younger children were at particular risk of poor HRQoL. Conclusions Additional research to identify the specific sources of poorer HRQoL among at-risk donors (eg, the donation experience vs having a chronically ill sibling) and the reasons that parents may be overestimating HRQoL in their donor children is critical and should lead to interventions and policy changes that ensure positive experiences for these minor donors.

There has been a lack of systematic in-depth research on the motives of living liver donors before transplantation that could contribute to an advanced understanding of their situation and to a more precise psychosocial evaluation, to protect the autonomy for decision, and to prevent psychosocial complications. Twenty-eight living liver donors were assessed preoperatively through a semistructured clinical interview. The taped and transcribed interviews were analyzed using a combination of grounded theory and empirically grounded type construction. Various factors contribute to the donor's motivation for donation: the relationship to the recipient, the personal attitude of the donor, his or her personal history, family dynamics, the donor's personal profit, and the exceptional situation of the recipient's life-threatening disease combined with the life-rescuing possibility of living-donor liver transplantation (LDLT). In reference to this, five "ideal types" of living donors emerged from the authors' data. A complete absence of coercion on the decision to donate seems unrealistic because of the dynamics initiated by the life-threatening condition of the recipient. It is important that donors feel they are gaining something by donation to be sufficiently motivated and that their profit is of an emotional or moral nature (i.e., the donation being set in an emotionally meaningful context). A mature relationship with the recipient usually provides such a context. The role of the clinician as a part of LDLT dynamics has a decisive influence.

The collection of peripheral blood progenitor cells (PBPC) by apheresis has become common in related allogeneic donors. However, the acceptability of the procedure to donors has not been documented. The purpose of this baseline case series study was to evaluate the psycho-social dimensions of apheresis from the perspective of healthy sibling donors and to explore issues surrounding fully informed consent including voluntary donation. At the first interview to discuss donation, 17 consecutive human leucocyte antigens (HLA) identical sibling donors who chose to donate PBPC were recruited to the study. They then completed both scales of the State-Trait Anxiety Inventory. The state scale was completed again immediately before first apheresis. At the end of the final apheresis, the donors were interviewed again by an independent researcher using a standardised questionnaire. All aspects of the procedure were well tolerated, including levels of anxiety and pain. Donors donated even if the relationship with their sibling was poor. However, some areas for improvement were highlighted. Eight (47%) donors were asked to donate by their sibling or another close relative, and this gave them no real volunteer status. Written information was judged important by 11 (65%) donors, but the material used was limited. The possibility of a poor outcome for the recipient was not well understood. The content of the written documentation and the management of confidentiality in terms of donor volunteer status needed to be addressed. A further study regarding the follow-up needs of donors, including those where the outcome is poor, is underway. Copyright 2003 Wiley-Liss, Inc.

STUDY QUESTION How do heterosexual parents reason about and experience information-sharing with offspring following identity-release sperm donation? SUMMARY ANSWER Sharing information about using donor-conception with offspring is a complex process at several levels, with the parent's personal beliefs and the child's responses serving as driving or impeding forces for the information-sharing process. WHAT IS KNOWN ALREADY The overall view of disclosure in gamete donation has shifted from secrecy to openness, but there is still uncertainty among parents concerning how and when to tell the child about his/her genetic origin. Most research on donor-conceived families has focused on donation treatment under anonymous or known circumstances, and there is a lack of studies in settings with identity-release donations. STUDY DESIGN, SIZE, DURATION A qualitative interview study among 30 parents following identity-release sperm donation treatment. Interviews were conducted from February 2014 to March 2015. PARTICIPANTS/MATERIALS, SETTING, METHODS The present study is part of the prospective longitudinal Swedish Study on Gamete Donation (SSGD), including all fertility clinics performing gamete donation in Sweden. A sample of participants in the SSGD, consisting of heterosexual parents with children aged 7–8 years following identity-release sperm donation, participated in individual semi-structured interviews. MAIN RESULTS AND THE ROLE OF CHANCE The analysis revealed one main theme: information-sharing is a process, with three subthemes; (i) the parent as process manager, (ii) the child as force or friction and (iii) being in the process. The first two subthemes were viewed as being linked together and their content served as driving or impeding forces in the information-sharing process. LIMITATIONS, REASONS FOR CAUTION The fact that the study was performed within the context of the Swedish legislation on identity-release donation must be taken into consideration as regards transferability to other populations, as this may affect parents' reasoning concerning their information-sharing with the child. WIDER IMPLICATIONS OF THE FINDINGS The present findings highlight the role of the donor-conceived child in the information-sharing process and may contribute to develop counselling that increases parents' confidence in handling children's reactions to information about their genetic origin.

In the case of organ donation, the family is highly involved in the decision process. To assess experience of organ donation process and grief symptoms in relatives of brain dead patients who discussed organ donation in the ICU. Multicentre cross-sectional study in 28 ICUs in France. Participating subjects were relatives of brain dead patients who were approached to discuss organ donation. Relatives were followed-up by phone at 3 time points: at 1 month to complete a questionnaire describing their experience of organ donation process; At 3 months to complete the Hospital Anxiety and Depression Scale and the Impact of Event Scale-Revised; At 9 months, to complete the IES-R and the Inventory of Complicated Grief. 202 relatives of 202 patients were included, of whom 158 consented and 44 refused organ donation. Interviews were conducted at 1, 3 and 9 months for 157, 137 and 117 relatives respectively. Experience was significantly more burdensome for relatives of non-donors. However there were no significant differences in grief symptoms measured at 3 and 9 months between the 2 groups. Understanding of brain death was associated with grief symptoms with higher prevalence of complicated grief symptoms in relatives who did not understand (75% vs 46.1%, p=0.026). Experience of the organ donation process varies between relatives of donor vs non-donor patients with relatives of non-donors experiencing lower quality communication, but the decision was not associated with subsequent grief symptoms. Importantly, understanding of brain death is a key element for relatives.

Power and Agenda-Setting in Tanzanian Health Policy: An Analysis of Stakeholder Perspectives

PubMed Central

Fischer, Sara Elisa; Strandberg-Larsen, Martin

2016-01-01

Background: Global health policy is created largely through a collaborative process between development agencies and aid-recipient governments, yet it remains unclear whether governments retain ownership over the creation of policy in their own countries. An assessment of the power structure in this relationship and its influence over agenda-setting is thus the first step towards understanding where progress is still needed in policy-making for development. Methods: This study employed qualitative policy analysis methodology to examine how health-related policy agendas are adopted in low-income countries, using Tanzania as a case study. Semi-structured, in-depth, key informant interviews with 11 policy-makers were conducted on perspectives of the agenda-setting process and its actors. Kingdon’s stream theory was chosen as the lens through which to interpret the data analysis. Results: This study demonstrates that while stakeholders each have ways of influencing the process, the power to do so can be assessed based on three major factors: financial incentives, technical expertise, and influential position. Since donors often have two or all of these elements simultaneously a natural power imbalance ensues, whereby donor interests tend to prevail over recipient government limitations in prioritization of agendas. One way to mediate these imbalances seems to be the initiation of meaningful policy dialogue. Conclusion: In Tanzania, the agenda-setting process operates within a complex network of factors that interact until a "policy window" opens and a decision is made. Power in this process often lies not with the Tanzanian government but with the donors, and the contrast between latent presence and deliberate use of this power seems to be based on the donor ideology behind giving aid (defined here by funding modality). Donors who used pooled funding (PF) modalities were less likely to exploit their inherent power, whereas those who preferred to maintain maximum control over the aid they provided (ie, non-pooled funders) more readily wielded their intrinsic power to push their own priorities.

We wanted to choose us: how embryo donors choose recipients for their surplus embryos.

PubMed

Goedeke, S; Daniels, K

2018-04-01

This study aimed to explore factors affecting donors' choice of recipients for their surplus embryos in the New Zealand context of conditional, known donations. Internationally, embryo donation has a low uptake in spite of large numbers of cryopreserved embryos. Possible reasons include a lack of knowledge about and concern for the future welfare of the resultant offspring. In New Zealand, donors and recipients meet prior to donation and legislation supports disclosure and access to genetic knowledge. Twenty-two embryo donors (10 couples, two individuals) were interviewed between March 2012 and February 2013 about their experiences of donation and factors affecting their donation. Interview data were analysed thematically. In the interests of the welfare of the child resulting from donation, donors were invested in choosing recipients who would make suitable parents. They attempted to choose recipients similar to themselves, as well as those that they trusted to disclose the manner of conception and facilitate agreed-upon information exchange and contact. The interest of donors in ensuring offspring well-being may lend support to conditional forms of open donation, allowing for assessment of recipients' suitability to parent, and for negotiation around information exchange and contact.

Live kidney donation is generally viewed as a welcome treatment option for severe kidney disease. However, there is a disparity in the body of research on donor experiences and postdonation outcome, and lack of knowledge on long-term consequences described by the donors. This study was conducted to provide insight into donors' subjective meanings and interpretation of their experiences ∼10 years after donation. Qualitative explorative in-depth interviews. The sampling strategy employed maximum variation. Setting Oslo University Hospital is the national centre for organ transplantation and donation in Norway, and there are 26 local nephrology centres. 16 donors representing all parts of Norway who donated a kidney in 2001-2004 participated in the study. The interviews were analysed using an interpretative approach. The analysis resulted in 4 main themes; the recipient outcome justified long-term experiences, family dynamics-tension still under the surface, ambivalence-healthy versus the need for regular follow-up, and life must go on. These themes reflect the complexity of live kidney donation, which fluctuated from positive experiences such as pride and feeling privileged to adverse experiences such as altered family relationships or reduced health. Live kidney donors seemed to possess resilient qualities that enabled them to address the long-term consequences of donation. The challenge is to provide more uniform information about long-term consequences. In future research, resilient qualities could be a topic to explore in live donation.

Ferreira, Oranice; Passos, Afonso Dinis Costa

2012-01-01

Objective This study aimed to investigate the frequency of positive results for hepatitis B and C, HIV and syphilis in blood donations at the Centro Regional de Hemoterapia de Ribeirão Preto, to describe donors with positive results according to some demographic and socioeconomic variables, to identify risk factors associated to these donors and the reasons that they were not detected during clinical screening. Methods A descriptive study was performed between July 1st 2005 and July 31st 2006 by interviewing 106 donorsafter medical consultations where they were informed of positive results for hepatitis B, hepatitis C, HIV or syphilis. Results There was a predominance of first-time donors, males, under 50-year olds, married individuals, from Ribeirão Preto, with elementary education, low economic status and of people who donated at the request of friends or relatives. Hepatitis C was the most frequently detected infection (56.6%), followed by hepatitis B (20.7%), HIV (12.3%) and syphilis(10.4%). About 40% of donors had omitted risk factors for different reasons: because they trusted the results of serological tests, did not feel comfortable about talking of risk factors or did not consider them relevant. Other justifications were the duration of the interview, the interviewer was unskilled, embarrassment and doubts about confidentiality. Conclusion The results indicate the need for changes in the approach to clinical screening and a review of methods to attract and guide potential donors. PMID:23323063

Organ donation remains a major public health challenge with over 114 000 people on the waitlist in the United States. Among other factors, extant research highlights the need to improve the identification and timely referral of potential donors by hospital health-care providers (HCPs) to organ procurement organizations (OPOs). We implemented a national test of the Rapid Assessment of hospital Procurement barriers in Donation (RAPiD) to identify assets and barriers to the organ donation and patient referral processes; assess hospital–OPO relationships and offer tailored recommendations for improving these processes. Having partnered with seven OPOs, data were collected at 70 hospitals with high donor potential in the form of direct observations and interviews with 2358 HCPs. We found that donation attitudes and knowledge among HCPs were high, but use of standard referral criteria was lacking. Significant differences were found in the donation-related attitudes, knowledge and behaviors of physicians and emergency department staff as compared to other staff in intensive care units with high organ donor potential. Also, while OPO staff were generally viewed positively, they were often perceived as outsiders rather than members of healthcare teams. Recommendations for improving the referral and donation processes are discussed. PMID:22900761

Confidentiality of personal identifiers potentially linking the genetic results from biobanking participants back to the donor and donor relatives is a concern. The risks associated with a breach of confidentiality should be ascertained when biobanks collect samples requiring the consent of a family decision maker (FDM) from deceased organ and tissue donors. This article explores FDM knowledge and opinions regarding risks associated with participation in biobanking research in the context of the Genotype-Tissue Expression (GTEx) Project. Data collection included a survey completed by organ procurement organization requesters (n = 37) and semistructured telephone interviews with the FDMs (n = 85). Donor families were more likely to know that there was a risk that a patient's identity could be revealed through a breach of confidentiality (p < 0.05). They also were more likely to understand that researchers using biobanked tissue would not have access to the patient's exact identity (p < 0.05). FDMs who refused donation were more concerned about risks than donors and reported lower levels of support for medical research in general. Finally, families were frequently interested in the return of results and willing to trade absolute confidentiality for participation. Clear discussion of the risk of breach of confidentiality is needed during the consent process. The risk and benefit equation could be equalized if studies such as GTEx offered genomic results to interested participants.

Breast milk donation: women's donor experience.

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

Keeping a tight grip on the reins: donor control over aid coordination and management in Bangladesh.

PubMed

Buse, K

1999-09-01

A long-standing consensus that aid coordination should be owned by recipient authorities has been eclipsed by accord on the desirability of recipient management of aid along-side domestic resources. Nonetheless, in many low and lower-middle income countries, donors remain remarkably uncoordinated; where attempts at coordination are made, they are often donor-driven, and only a small proportion of aid is directly managed by recipients. This paper draws on evidence from an in-depth review of aid to the health sector in Bangladesh to analyze the systems by which external resources are managed. Based on interviews with key stakeholders, a questionnaire survey and analysis of documentary sources, the factors constraining the government from assuming a more active role in aid management are explored. The results suggest that donor perceptions of weak government capacity, inadequate accountability and compromised integrity only partially account for the propensity for donor leadership. Equally important is the consideration that aid coordination has a markedly political dimension. Stakeholders are well aware of the power, influence and leverage which aid coordination confers, an awareness which colours the desire of some stakeholders to lead aid coordination processes, and conditions the extent and manner by which others wish to be involved. It is argued that recipient management of external aid is dependent on major changes in the attitudes and behaviours of recipients and donors alike.

Family informed consent to organ donation--who performs better: organ procurement organizations, in-hospital coordinators, or intensive care unit professionals?

Successful organ donation in countries adopting informed consent legislation depends on adequate interviewing of potential donors' families. As the number of both referral and effective donors in Brazil increases, health care managers argue whether educational efforts should be directed toward training in-hospital coordinators (IHC)--based on the "Spanish model"--or on the creation of extra-hospital-based professionals (Organ Procurement Organizations [OPOs], the "American model"). Meanwhile, many potential donor families are still approached by intensive care unit (ICU) professionals not trained in donation interviews. The aim of our study was to compare performances in obtaining informed consent from potential donors' families, according to the type of health care professional conducting the interviews: OPO, IHC, or ICU staff. In this retrospective 2-year study performed in Rio de Janeiro, Brazil, we observed an increase in referrals (285 to 411) and consent rates (48.1% to 55.7%). Each year, OPO professionals conducted most family interviews (58.6% and 60.4%, respectively) and obtained better consent rates (63.5% and 64.5%, respectively), when compared to IHC (41.8% and 53.7%, respectively) or untrained ICU professionals (22.1% and 13.4%, respectively). Our results show that adequate professional training is necessary for obtaining family consent for organ donation. Both established international policies for organ procurement and donation, namely the "Spanish model" with its IHCs or the "American model" of extra-hospital OPOs, may equally achieve this task. However, family interviews performed by untrained ICU professionals result in low donation rates and should be discouraged. Copyright © 2014 Elsevier Inc. All rights reserved.

Blood donors' preferences for blood donation for biomedical research.

Increasing numbers of blood donors are recruited to participate in biomedical research. As blood services depend on voluntary donors, successful recruitment calls for a better understanding of donors' expectations and attitudes toward the use of samples in research. Sixty-one semistructured interviews were conducted with blood donors at eight Finnish Red Cross Blood Service donation sites in Finland. The 10- to 30-minute interviews included open-ended questions about donors' views on blood donation for patients and for biomedical research. Central motives to donate blood for patients were identified against which views on research use were compared to see how these reflections differed. Six central motives for donating blood for patients were identified among donors. The interviewees were, in general, willing to donate blood for research, but considered research donation more likely if it could be easily integrated into their usual blood donation habits. Biomedical research was perceived as important but its social benefits were more abstract than a direct help to patients. Familiarity and reciprocity were key to the relationship between the blood service and blood donors. Donation for research introduces a new, more complex context to blood donation. Challenge to recognize concrete outcomes and benefits of donation may affect willingness to donate for research. Transparent communication of the role of the blood service in research and of the beneficiaries of the research is essential in maintaining trust. These results will help blood services in their planning to recruit blood donors for research projects. © 2018 The Authors Transfusion published by Wiley Periodicals, Inc. on behalf of AABB.

The Core of Sibling Stem Cell Donation – A Grounded Theory Study

PubMed Central

Kisch, Annika M; Forsberg, Anna

2017-01-01

Background: There is a lack of theoretical framework supporting stem cell transplant nurses in their assessment, judgment and caring interventions of sibling stem cell donors. Objective: The purpose of this study was to explore sibling stem cell donors’ main concerns and how they deal with them before and after donation. Method: Ten healthy sibling donors, 5 men and 5 women, with a median age of 54 years were included in this study when they were due to donate stem cells to a brother or sister. Data were collected prospectively on three occasions (before the donation and three and twelve months after it) through in-depth interviews, which were recorded and transcribed verbatim for analysis by the Grounded Theory method according to Charmaz. Results: This study describes the efforts of the ten donors to fulfil their duty as a sibling by doing what they considered necessary in order to help. Their efforts were summarised in a process wherein the grounded theory generated three main categories; Prepare, Promote and Preserve. A clear path of transition leading to fulfilment is evident, starting before the donation and continuing for one year afterwards. Conclusions: Being a sibling stem cell donor means doing what you have to do to fulfil your duty and if possible, saving the life of a seriously ill brother or sister. The relationship between the siblings is strengthened by the donation process. Sibling stem cell donation appears to be about fulfilment and the theoretical framework may support clinicians in their evaluation and support of donors. PMID:28839511

Indefinite deferral from donation for any man who discloses having had sex with another man even once since 1977 (MSM77) is the US FDA's standing policy. This qualitative component of the Blood Donation Rules and Opinion Study was designed to provide insight into the perceptions and practices of current or previous donors with MSM history. Forty human immunodeficiency virus (HIV)-negative MSM completed an online survey, indicating that they had donated blood and were willing to be interviewed. Semistructured, individual interviews with these key informants covered donation experience and motivations, perceptions of MSM77, policy change preferences, and possible impact of a change to a time-limited deferral. Transcripts were coded deductively and inductively, following a modified Grounded Theory approach. Analysis identified recurrent and divergent themes. Ninety-five percent of participants endorsed modifying MSM77. Preferred deferral length ranged from none to 5 years; a common opinion was that a science-based deferral period would be less than 1 year. Other policy change recommendations included incorporating questions about specific HIV risk behaviors to the donor questionnaire for all potential donors. Interviewees recognized HIV infection rates are higher in MSM than the general US population, but participants considered themselves low-risk for HIV, donated blood "to save lives," and justified their recommendations as being more effective ways to identify donors at risk for HIV. Results suggest that MSM donors are concerned with blood safety; they can be appealed to as such. Communications about a new deferral policy should include scientific explanations and acknowledge altruistic motivations of potential donors. © 2015 AABB.

The experience of receiving a kidney transplant from a deceased donor: Implications for renal services.

Lonargáin, Diarmaid Ó; Brannigan, Dawn; Murray, Craig

2017-02-01

The study aimed to explore the psychological experiences of receiving a kidney transplant from a deceased donor and to examine resulting implications for renal services. A qualitative design was utilised within an interpretative phenomenological analysis (IPA) framework. Semi-structured interviews were conducted with six adults (male = 5, mean age = 45 yrs) on their experiences of receiving a kidney transplant from a deceased donor. All participants had their transplant within the preceding 21 months. Data were analysed using IPA. The four elicited themes incorporate recipients' positive feelings about receiving a transplant, mainly arising from the newfound freedom that this entails, in addition to strong feelings of gratitude towards their donors. They also capture challenges, such as the uncertainty of living with a transplanted kidney, and highlight the increased dependence on others throughout the transplant process. The findings indicate a range of psychological, social and occupational experiences for participants. It is concluded that optimal care in renal services would incorporate a holistic approach to pre and post-transplant care; identifying and supporting the needs of transplant recipients. A biopsychosocial model of care may enhance service user well-being. Potential areas of future research are explored.

Addressing inequities is a key role for international non-governmental organizations (INGOs) working in health and development. Yet, putting equity principles into practice can prove challenging. In-depth empirical research examining what influences INGOs' implementation of equity principles is limited. This study examined the influences on one INGO's implementation of equity principles in its HIV/AIDS programs. This research employed a case study with nested components (an INGO operating in Kenya, with offices in North America). We used multiple data collection methods, including document reviews, interviews (with staff, partners and clients of the INGO in Kenya), and participant observation (with Kenyan INGO staff). Participant observation was conducted with 10 people over three months. Forty-one interviews were completed, and 127 documents analyzed. Data analysis followed Auerbach and Silverstein's analytic process (2003), with qualitative coding conducted in multiple stages, using descriptive matrices, visual displays and networks (Miles and Huberman, 1994). There was a gap between the INGO's intent to implement equity principles and actual practice due to multiple influences from various players, including donors and country governments. The INGO was reliant on donor funding and needed permission from the Kenyan government to work in-country. Major influences included donor agendas and funding, donor country policies, and Southern country government priorities and legislation. The INGO privileged particular vulnerable populations (based on its reputation, its history, and the priorities of the Kenyan government and the donors). To balance its equity commitment with the influences from other players, the INGO aligned with the system as well as pushed back incrementally on the donors and the Kenyan government to influence these organizations' equity agendas. By moving its equity agenda forward incrementally and using its reputational advantage, the INGO avoided potential negative repercussions that might result from pushing too fast or working outside the system. The INGO aligned the implementation of equity principles in its HIV/AIDS initiatives by working within a system characterized by asymmetrical interdependence. Influences from the donors and Kenyan government contributed to an implementation gap between what the INGO intended to accomplish in implementing equity principles in HIV/AIDS work and actual practice.

Surgical use of donor corneal tissue from victims of water submersion (drowning or submersion secondary to death) remains controversial due to limited evidence about the quality of these tissues. To assess the safety of donor corneal tissue from victims of water submersion, an investigation of eye banks' practice patterns and tissue outcomes was conducted. All 79 Eye Bank Association of America accredited eye banks were contacted for a phone interview of practices regarding tissue from victims of water submersion. A retrospective review of corneal tissues from 2014 to 2016 from a large eye bank network was performed to identify all donors submerged in water. Corneal epithelial integrity, endothelial cell density (ECD), rim cultures, and adverse events were analyzed for associations with water submersion characteristics. 49 eye banks (62% response) participated in the survey. 55% of these eye banks had specific, written protocol for tissue eligibility from donors submerged in water. With or without specific protocol, eye banks reported considering water type (84%) and length of time submerged (92%) to determine eligibility. 22% of eye banks reported medical director involvement when eligibility determination was unclear. 79 tissues from 40 donors who were submerged were identified in 2014-2016 eye bank data. No donor tissues had pre-processing corneal infiltrates, positive rim cultures, or adverse events post-keratoplasty. Corneal epithelial integrity and ECD were not associated with water type or length of time submerged. In conclusion, data from a large eye bank network showed no adverse events or outcomes, indicating these tissues may be safe.

Summary Background As Japan's aging society needs more blood, young students comprise a progressively smaller portion of the donor pool. To ensure a safe and sustainable blood supply, it is crucial to select suitable donors. This study aims to evaluate donor deferral rates, causes of deferral, and characteristics of deferred Japanese students. Methods Computerized records of blood centers in northern Japan (Miyagi and Fukushima Prefectures) from March 2010 through March 2011 were retrospectively analyzed. Results Among 231,361 individuals visiting during the 12-month period, 24,778 were students. Of these, 19,193 (77%) attempted donation, and 5,585 (23%) were deferred. Low hemoglobin, questionnaire-based interview decisions, and medication were the main reasons for temporary deferral. Age, sex, and blood center location were associated with low hemoglobin; donation history and blood center location were associated with medication-based deferral. The odds ratio among female students deferred for low hemoglobin was 35.48 with a 95% CI of 27.74–45.38. Conclusions These results suggest that continued efforts are needed to motivate deferred potential donors to return, to prevent low hemoglobin especially among females, and to review medical interview decisions, while paying close attention to regional differences.

Body dirt or liquid gold? How the 'safety' of donated breastmilk is constructed for use in neonatal intensive care.

PubMed

Carroll, Katherine

2014-06-01

When mothers of preterm infants are unable to produce sufficient volumes of breastmilk, neonatologists in many Western countries prescribe pasteurized donor breastmilk. Breastmilk has a paradoxical presence in the neonatal intensive care unit while it has therapeutic properties, it also has the potential to transmit disease. National health authorities and local neonatal intensive care unit policies each delimit the safety of donor milk by focusing on the presence or absence of pathogens. It is in this light that breastmilk from the human milk bank is both sought and legitimated to minimize safety concerns. This research uses data arising from an ethnographic study of two human milk banks and two neonatal intensive care units in the United States, and 73 interviews with milk donors, neonatal intensive care unit parents and clinicians. The primary research question framing the study was 'What are the underlying processes and practices that have enabled donor milk to be endorsed as a safe and legitimate feeding option in neonatal intensive care units?' This study is framed using three key principles of Latour's 'new critique', namely, adding to reality rather than debunking it, getting closer to data rather than turning away from fact and creating arenas in which to assemble. As a result, conceptions of donor milk's safety are expanded. This case study of donor milk demonstrates how Latour's new critique can inform science and technology studies approaches to the study of safety in health care.

Whole-blood donation: blood donor suitability and adverse events.

PubMed

Newman, Bruce H

2004-11-01

Approximately 3% to 3.5% of the US population donates whole blood each year. Physicians might be approached by a blood donor because of a donor suitability issue, a positive postdonation test, or a donation-related complication. Approximately 83% of blood donors successfully donate; but 13% are rejected because of a donor suitability issue; 1% have a positive test, which is often nonspecific or false-positive; and 2% to 4% of the phlebotomies are not successful. The most common adverse physical events based on donor interviews are bruise (23%), sore arm (10%), fatigue (8%), and vasovagal reaction (7%), while uncommon events include nerve irritation (0.9%), syncope (0.1-0.3%), and arterial puncture (0.01%). One in 3400 donors (0.033%) report seeking outside medical care. Serious injuries occur but are very rare. More often, blood donors do well and feel satisfied with the blood donation experience.

Laparoscopic donor nephrectomy increases the supply of living donor kidneys: a center-specific microeconomic analysis.

PubMed

Kuo, P C; Johnson, L B

2000-05-27

A tenet of microeconomics is that new technology will shift the supply curve to the right. Laparoscopic donor nephrectomy (LDN) is a new technique for removal of living donor kidneys. Centers performing this procedure have noted an increased number of patients presenting for donor evaluation. This has not been previously studied. The records of all LDN performed from May 1998 to February 1999 were reviewed. The following variables were examined: sex, age, related vs. unrelated donation, estimated blood loss, i.v. analgesia, length of stay, and time out of work. Donors undergoing traditional open donor nephrectomy during January 1997 to May 1998 served as the control group. A composite cost index was constructed. LDN significantly decreased length of stay, pain, and time out of work; the supply function shifted to the right. Telephone interviews revealed that 47% donated solely because of the LDN procedure. LDN increases the supply of living donor kidneys.

BACKGROUND 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. STUDY DESIGN AND METHODS 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. RESULTS 13 of 16 participants reported a variably high percentage of women who consented to public cord blood donation. 15 banks offered donor registration at the time of hospital admission for labor and delivery. 7 obtained full informed consent and medical history during early labor and 8 conducted some form of phased consent and/or phased medical screening and history. 9 participants identified initial selection of the collection site location as the chief mode by which they recruited minority donors. CONCLUSION 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. PMID:22803637

In this study we propose a theoretical and practical basis for the best practices for interviewing relatives of brain-dead eligible organ donors. This investigation was a reflective study of the methodologic factors of the family interview that affect their decision regarding the donation of a deceased patient's organs for transplantation. The articles that formed the empirical basis of the trial were obtained from PubMed, which is a free-access tool of the MEDLINE database of the United States National Library of Medicine. Published articles that allowed us to reflect on evidence-based family interview practice were selected. Thirty-six scientific articles were used to guide our assessment the family interview, providing evidence for its adequate execution in view of the following prerequisites: When should the family interview be performed? Where should it be done? How many and which people should participate in the interview? Who should perform it? How should it be done? Scientific studies offer evidence to donation and transplantation specialists that can help them in their daily work regarding their interactions with relatives in the process of decisionmaking and family consent.

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

Psychosocial counselling of identifiable sperm donors.

What do identifiable sperm donors feel about psychosocial counselling? Identifiable sperm donors found it important that psychosocial counselling focused on emotional consequences and on rules and regulations and they expected to have access to psychosocial counselling at the time that donor-offspring actually sought contact. Most studies on sperm donors are on anonymous donors and focus on recruitment, financial compensation, anonymity and motivations. There is limited knowledge on the value that identifiable sperm donors place on psychosocial counselling and what their needs are in this respect. We performed a qualitative study from March until June 2014 with 25 identifiable sperm donors, who were or had been a donor at the Centre for Reproductive Medicine of the Academic Medical Centre in Amsterdam any time between 1989 and 2014. We held semi-structured in-depth interviews with identifiable sperm donors with an average age of 44 years. The interviews were fully transcribed and analysed using the constant comparative method of grounded theory. Twelve out of 15 donors (former donors ITALIC! n = 8, active donors ITALIC! n = 7) who had received a counselling session during their intake procedure found it important that they had been able to talk about issues such as the emotional consequences of donation, disclosure to their own children, family and friends, future contact with donor-offspring and rules and regulations. Of the 10 former donors who had received no counselling session, 8 had regretted the lack of intensive counselling. In the years following their donation, most donors simply wanted to know how many offspring had been born using their sperm and had no need for further counselling. Nevertheless, they frequently mentioned that they were concerned about the well-being of 'their' offspring. In addition, they would value the availability of psychosocial counselling in the event that donor-offspring actually sought contact. A limitation of our study is its generalizability, since only a small number of identifiable donors at a single centre were studied. Variation in how donors are counselled upon intake may affect how donors value psychosocial counselling. This study reports on the issues that identifiable donors value being addressed during their intake procedure, as well as during counselling in the event that donor-offspring actually seek contact. These findings can be used to achieve a higher quality of care for identifiable sperm donors and may be the starting point for developing guidelines on psychosocial counselling for sperm donors. No funding was obtained for this study. The authors have no conflicts of interest to declare. © The Author 2016.

Factors influencing resource allocation decisions and equity in the health system of Ghana.

PubMed

Asante, A D; Zwi, A B

2009-05-01

Allocation of financial resources in the health sector is often seen as a formula-driven activity. However, the decision to allocate a certain amount of resources to a particular health jurisdiction or facility may be based on a broader range of factors, sometimes not reflected in the existing resource allocation formula. This study explores the 'other' factors that influence the equity of resource allocation in the health system of Ghana. The extent to which these factors are, or can be, accounted for in the resource allocation process is analysed. An exploratory design focusing on different levels of the health system and diverse stakeholders. Data were gathered through semi-structured qualitative interviews with health authorities at national, regional and district levels, and with donor representatives and local government officials in 2003 and 2004. The availability of human resources for health, local capacity to utilize funds, donor involvement in the health sector, and commitment to promote equity have considerable influence on resource allocation decisions and affect the equity of funding allocations. However, these factors are not accounted for adequately in the resource allocation process. This study highlights the need for a more transparent resource allocation system in Ghana based on needs, and takes into account key issues such as capacity constraints, the inequitable human resource distribution and donor-earmarked funding.

Outcomes of organ donation in brain-dead patient's families: Ethical perspective.

2017-01-01

The families of brain-dead patients have a significant role in the process of decision making for organ donation. Organ donation is a traumatic experience. The ethical responsibility of healthcare systems respecting organ donation is far beyond the phase of decision making for donation. The principles of donation-related ethics require healthcare providers and organ procurement organizations to respect donor families and protect them against any probable harm. Given the difficult and traumatic nature of donation-related experience, understanding the outcomes of donation appears crucial. The aim of this study was to explore the outcomes of organ donation for the families of brain-dead patients. This was a qualitative descriptive study to which a purposeful sample of 19 donor family members were recruited. Data were collected through holding in-depth semi-structured interviews with the participants. Data analysis was performed by following the qualitative content analysis approach developed by Elo and Kyngäs. The main category of the data was "Decision to organ donation: a challenge from conflict to transcendence." This main category consisted of 10 subcategories and 3 general categories. The general categories were "challenging outcomes," "reassuring outcomes," and "transcending outcomes." Ethical considerations: The study was approved by the regional ethical review board. The ethical principles of informed consent, confidentiality, and non-identification were used. Donor families experience different challenges which range from conflict and doubtfulness to confidence, satisfaction, and transcendence. Healthcare providers and organ procurers should not discontinue care and support provision to donor families after obtaining their consent to donate because the post-decision phase is also associated with different complexities and difficulties with which donor families may not be able to cope effectively. In order to help donor families achieve positive outcomes from the tragedy of significant loss, healthcare professionals need to facilitate the process of achieving confidence and transcendence by them.

Fetal tissue banking for transplantation: characteristics of the donor population and considerations for donor and tissue screening.

We initiated this study to evaluate the suitability for therapeutic use in transplantation of tissues obtained from human abortuses. We have developed protocols for the collection, handling and preservation of hepatic stem cells from electively aborted embryos and have developed methods for assessment of the cells so derived and processed. In this paper we present our findings regarding screening of potential donors, acquisition of fetal tissues, and assessment of the tissues for potentially infectious contaminants. We assess the suitability of the tissue donors according to current standards used for donors of commonly transplanted tissues (e.g., bone grafts, skin grafts and heart valves) and present data regarding the real availability of tissues from elective abortion procedures that would meet those standard tissue banking criteria.We specifically evaluated the donor's willingness to provide a blood sample for testing, conducted a detailed interview similar to those used for typical organ and tissue donors, and assessed the type and incidence of contamination in collected tissues. We find that although many women are willing to consent to use of the tissues for transplantation, attrition from the study for various reasons results in few fetal organs ultimately realistically available for transplantation. Typical reasons for attrition include: unwillingness to have a blood sample drawn or tested, positive serology results, social/medical high risk factors for acquisition of transmissible disease, no identifiable organs available, and unacceptable microbial contamination. Thus, although it might seem that due to the numbers of abortions performed annually, that there would be substantial numbers of suitable tissues available, only a small proportion are truly suitable for transplantation.

Over my dead body: body donation and the rise in donor registrations in The Netherlands.

PubMed

Bolt, Sophie; Eisinga, Rob; Altena, Marga; Venbrux, Eric; Gerrits, Peter O

In The Netherlands, the number of body donor registrations has been increasing for several years. Body donors are people who register at an anatomical institute to donate their entire body, after death, for scientific education and research. Although only 0.1% of the Dutch population is registered as a body donor, this is sufficient to realize the anatomical demand of about 650 bodies annually. Due to the recent rise of registrations many anatomical institutes have (temporarily) stopped registering new donors to prevent a surplus of bodies. Based on a large body donor survey (n=759) and in-depth anthropological interviews with 20 body donors, we try to give an explanation for the rising registration numbers. We argue that the choice for body donation in contemporary, individualized Dutch society is an autonomous way to give meaning and sense to life and death outside the framework of institutionalized religion.

The primary aim of this study was to assess potential barriers and motivators to blood and cord blood donation among African-American women. A telephone survey of African-American women, ages 18-30 years, in the St. Louis metropolitan area was performed. The survey was administered by trained telemarketing personnel using a Computer-Assisted Direct Interview (CADI) system. One hundred sixty-two women were surveyed. Common barriers to blood donation were inconvenience of donor sites (19%), fear of needles (16%), and too much time required to donate (15%). Potential motivators were increasing awareness of need for blood (43%), increasing the number of convenient donor locations (19%), and encouragement by spiritual leaders to have blood drives at their church (17%). Lack of awareness was the only identified barrier to cord blood donation. Most women surveyed (88%) indicated that they definitely or probably would donate cord blood. Strategies to increase the proportion of African-American blood and cord blood donations may include educating potential donors about the process and benefits of donation to particular patient populations and engaging church leadership in supporting blood and cord blood donations.

Surrogacy families headed by gay men: relationships with surrogates and egg donors, fathers' decisions over disclosure and children's views on their surrogacy origins.

How do gay father families experience surrogacy in terms of their relationships with surrogates and egg donors, fathers' disclosure decisions and children's views on their surrogacy origins? More families had a relationship with the surrogate than the egg donor, and almost all had started to disclose to their children, the majority of whom expressed limited interest in their surrogacy conception. Gay fathers tend to report greater contact with the surrogate than the egg donor and to disclose only the use of a surrogate (omitting discussion of the egg donor and the respective fathers' genetic relatedness). Children's views on their surrogacy conception to gay fathers are not known. Thirty-one children and 80 fathers were interviewed as part of a larger in-depth investigation of 40 Italian gay father surrogacy families. Multiple strategies were used to recruit participants. Children were aged 6-12 years and had been born to gay fathers through gestational surrogacy. Semi-structured interviews were conducted in participants' homes with each family member, separately. Fathers' interviews were presented from the perspective of the father who identified as being most involved with the child on a day-to-day basis. Qualitative content analysis was performed and quotations illustrating the findings were reported. Where appropriate, comparisons were conducted using χ2 or Fisher's exact tests. A total of 31 children in 24 families were interviewed. Most families reported a harmonious relationship with the surrogate (n = 20, 57.1%) and a distant relationship with the donor (n = 10, 66.7%) (χ2(1) = 23.33, P < 0.001). Before the child was aged 4 years, almost all families (n = 34, 85%) had started to disclose their use of a surrogate, with 16 families (n = 16, 40%) also disclosing their use of a donated egg, and only 4 (10%) disclosing which father's sperm had been used. Of the 31 children interviewed, most (n = 17, 54.8%) showed a clear understanding of their conception. About 19 (61.3%) expressed limited interest in their conception, 11 (35.5%) felt positive and 1 child (3.2%) was unsure how he felt. Children differed in their feelings towards their surrogate and egg donor (Fisher's exact test, P = 0.002). Of the 31 children who were aware of the surrogate, the majority felt grateful towards her (n = 22, 71%), while of the 25 children who were also aware of the egg donation, 11 (44%) showed limited interest in their donor. The sample's convenience nature and the gay father families' high income limited the representativeness of the findings. Further, some children belonged to the same family, and this could have biased the results, as these children may have had similar experiences. Prior to this study, the voice of children conceived by gay fathers through surrogacy had not been heard. Future research on factors influencing children's desired contact with-or interest in-the surrogate and/or egg donor and their feelings when contact is not possible will be important in preparing families for such events. Support was obtained from a Sapienza Starting Grant for Research to the first author (grant number AR11715C77EB56B2). None of the authors has any conflict of interest. © The Author 2017.

Prior Family Communication and Consent to Organ Donation: Using Intensive Care Physicians’ Perception to Model Decision Processes

2012-01-01

Generally, the Swiss hold favourable attitudes to organ donation, but only few carry a donor card. If no card is found on a potential donor, families have to be approached about donation. The aim of this paper is to model the role that some family communication factors play in the family decision to consent or not to organ donation by a brain dead relative. Information was gathered in face-to-face interviews, using a questionnaire and recording open answers and comments. Eight heads of intensive care units (ICU) of Swiss hospitals and one representative from Swisstransplant were interviewed. Questions asked respondents to estimate the prevalence and effect of communication factors in families facing a decision to consent to donation. Answers were averaged for modelling purposes. Modelling also relies on a previous representative population survey for cross-validation. The family of the deceased person is almost always approached about donation. Physicians perceive that prior thinking and favourable predisposition to donation are correlated and that the relatives’ predisposition is the most important factor for the consent to donation, up to the point that a negative predisposition may override an acknowledged wish of the deceased to donate. Donor cards may trigger family communication and ease the physicians’ approach to family about donation. Campaigns should encourage donate-willing people to talk to their families about it, make people think about organ donation and try to change unfavourable predispositions. Acknowledgement the authors wish to thank the interviewees whose collaboration has provided them an overview of today’s situation in Switzerland. PMID:25170455

Buying and selling human eggs: infertility providers' ethical and other concerns regarding egg donor agencies.

PubMed

Klitzman, Robert

2016-11-08

Egg donor agencies are increasingly being used as part of IVF in the US, but are essentially unregulated, posing critical ethical and policy questions concerning how providers view and use them, and what the implications might be. Thirty-seven in-depth interviews of approximately 1 h were conducted - with 27 IVF providers and 10 patients. Clinicians vary in their views and interactions concerning egg donor agencies, ranging widely in whether and how often they use agencies. Agencies may offer egg recipients increased choices, but raise ethical and other concerns regarding respect for donors as individuals (e.g., adequacy of informed consent), potential harms, justice (e.g., concerns about possible eugenics - by encouraging and facilitating selection and marketing of facts for offspring), and donors constituting a vulnerable group. The quality of agencies appears to vary considerably, from acceptable to problematic. Agencies' medical and psychological screenings of donors can range, and be minimal. Not all agencies adequately track donors' prior numbers of donations, or share the relevant records with clinics. Clinics may find that potential donors have genetic mutations and medical problems about which they were unaware. Yet agencies and clinics do not provide care for such donors, generating stress. Dissemination of donors' personal data can potentially threaten confidentiality. Questions emerge of whether increased monitoring/oversight of agencies may be beneficial. These data, the first to examine providers' views and interactions regarding egg donor agencies, suggest wide variations in quality and use of agencies, and have critical implications for practice, policy, education and research. Given the potential limitations of the current model of self-regulation of agencies, the present data suggest needs to consider stronger professional guidelines or possible governmental regulations to establish, require and enforce higher standards for agencies to follow, regarding advertising to potential donors and recipients, arranging for appropriate informed consent concerning risks and benefits involved, and for quality control. Appropriate informed consent should be obtained from potential egg donors, including the fact that they may learn about mutations or medical problems about which they were unaware, but for which they will not receive treatment as part of this process. Enhancing understanding among the public-at-large about what egg donation entails may also be helpful.

Donation of peripheral blood stem cells to unrelated strangers: A thematic analysis

2017-01-01

Background Donation of haematopoietic stem cells, either through bone marrow (BM) or peripheral blood stem cell (PBSC) collection, is a generally safe procedure for healthy donors, although side effects are a known risk. Previous research, including our recent quantitative study, has shown that the psychosocial response to donating is usually a positive one and most donors would be willing to donate again in the future. This is often despite experiencing significant side effects during the donation process. Due to the relative recent introduction of PBSC, a comprehensive understanding of the range of physical and emotional issues donors may experience is lacking, as well as an understanding of specific donor characteristics Qualitative research can provide rich narrative data into these areas. This study was set up in order to identify specific donor characteristics and to further explore the relationship between pre-donation physical health and the donation experience, as previously identified in our quantitative study. Methods It involved in-depth telephone interviews with 14 PBSC donors who participated in our original quantitative study. Thematic analysis was used to analyse the findings and the results provide a summary of participants’ characteristics using themes and constituent codes. Results We identified several donor characteristics, including strong intrinsic motivation, altruism, sense of duty, determination, low levels of ambivalence and the ability to develop a strong emotional relationship with an (unknown/anonymous) recipient whilst being able to manage strong feelings and emotions. Conclusions These personality traits may explain the resilience that has been observed previously in haematopoietic stem cells donors. Significant feelings of grief were reported after a recipient’s death. Possibilities to alleviate these symptoms may include raising awareness of potential poor outcomes in the recipient and offering improved counselling services if the recipient dies. We acknowledge several limitations including the sampling frame. PMID:29069088

The personality and motivation of semen donors: a comparison with oocyte donors.

PubMed

Schover, L R; Rothmann, S A; Collins, R L

1992-04-01

Seventeen consecutively recruited candidates for semen donation were evaluated by a psychologist with testing and a structured interview. Most men (71%) were motivated by financial compensation. Only 29% would donate semen if records were open to potential offspring. Fifty-nine per cent of the men were rated as excellent candidates from a psychological perspective and 35% were rated as acceptable with slight reservations. One was excluded as a donor. Psychological testing revealed mildly abnormal subscale scores for 35% of donors. Forty-seven per cent had histories of minor depressive or anxiety episodes and 35% had had periods of heavy alcohol use. Compared to oocyte donors at the same institution, the men were less altruistic, more affluent, and more likely to have abused alcohol. Women had more traumatic family and reproductive histories. Psychological evaluation can be a valuable tool in gamete donor selection.

Determine hepatitis C prevalence and risk factors in blood donors from the Blood Bank at the Centro Médico Nacional 20 de Noviembre ISSSTE, in Mexico City. A total of 41,957 blood donors were included in the study was done from January 1996 to August 2000. To study risk factors, a case-control study cases were defined as blood donors with repeatedly positive anti-hepatitis C virus (HCV) ELISA test. Controls were defined as blood donors with negative anti-HCV ELISA test. All cases were interviewed a second time on HCV infection-associated risk factors. Odd ratio (OR) and confidence interval 95% (CI 95%) were calculated for each risk factoring in a univariate analysis. Multivariate analysis was performed subsequents to determine the independent contribution or each risk factor. HCV crude total prevalence was 0.84%. Risk factors were found in 36.16% anti-HCV-positive blood donors. During the second interview, 30% of sero-positive blood donors recalled one or more risk factors they previously denied. The most important risk factors, found were as follows sexual relations with prostitutes (OR 7.48, CI 95% 1.43-38.92) transfusion (OR 6, CI 95% 2.62-13.72); nasal cocaine use (OR 8.89, CI 95%, 1.01-86.89); dental surgery (OR 8.89, CI 95% 1.01-86.89) and contact with hepatitis-infected subject (OR 3.01, CI 95% 1.17-7.70). Other risk factors did not show a significant association. In this study, we found a crude total prevalence of 0.84%, very close to the prevalence reported in Mexican population by the National Center for Blood Transfusion.

Between October 1988 and February 1989, 1,033 voluntary first-time blood donors were screened for hepatitis B infection in five blood banks in Goiâna, Central Brazil. The survey was part of a major study designed to estimate seroprevalence of HBsAg and anti-HBs and to discuss methodological issues related to prevalence estimation based on data from blood banks. Donors were interviewed and blood samples were collected and tested for HBsAg and anti-HBs by ELISA tests. Prevalences of 1.9% and 10.9% were obtained for HBsAg and anti-HBs, respectively, and no statistical difference was found between the sexes. Prevalence of anti-HBs increased with age (X2 for trend = 7.9 p = 0.004). The positive predictive value and sensitivity of history of jaundice or hepatitis reported in the interview in detecting seropositives were 13.6% and 2.2%, respectively. The methodological issues, including internal and external validity of HBV prevalence estimated among blood donors are discussed. The potential usefulness of blood banks as a source of morbidity information for surveillance for Hepatitis B virus infection is stressed.

'It seemed churlish not to': How living non-directed kidney donors construct their altruism.

Our objective was to explore how prospective altruistic kidney donors construct their decision to donate. Using a qualitative design and biographical-narrative semi-structured interviews, we aimed to produce text for analysis on two levels: the social implications for subjectivity and practice and a tentative psychodynamic explanation of the participants' psychological investment in the discourses they used. A total of six prospective altruistic kidney donors were interviewed. A psychosocial approach to the analysis was taken. In-depth discourse analysis integrated Foucauldian with psycho-discursive approaches and psychodynamic theory was applied to sections of text in which participants seemed to have particular emotional investment. Analysis generated three major discursive themes: other-oriented, rational and self-oriented discourses. The desire to donate was experienced as compelling by participants. Participants used discourses to position themselves as concerned with the needs of the recipient, to resist questioning and criticism, and to manage difficult feelings around mortality. Participants tended to reject personal motivations for altruistic donation, positioning relatives' disapproval as selfish and illogical. These results suggest that the term 'altruistic' for living non-directed organ donation constrains available discourses, severely limiting what can be said, felt, thought and done by donors, clinicians and the public. A more useful approach would acknowledge potential psychological motives and gains for the donor. © The Author(s) 2013.

'What Does Donor Mean to a Four-Year-Old?': Initial Insights into Young Children's Perspectives in Solo Mother Families.

This study reports on the questions, thoughts and feelings of children aged 4-9 conceived by donor insemination to single mothers. Fifty-one mothers and 47 children from the same families were each administered a semi-structured interview. Mothers generally reported that while children either lack understanding, or have not yet been told, about their donor conception, they may be thinking and talking about the absence of a father. Most children did not mention either donor conception or father absence and reported positive feelings about their families and friendships. Possible explanations for the discrepancy between mothers' and children's reports are discussed.

Laparoscopic donor nephrectomy: meeting the challenge of consumerism?

2003-11-01

Despite the increasing adoption of laparoscopic donor nephrectomy, no study has examined donor perceptions following this procedure. In particular, it has been tacitly assumed that a less invasive procedure might in itself provide a more satisfactory donor experience. The present study reviews the experience of donors undergoing laparoscopic nephrectomy, and examines the extent to which contemporary management practice addresses issues relevant to consumerism. Forty-two donors participated in a structured telephone interview, and 33 (79%) returned a written questionnaire. Coming through the survey was a strong sense of commitment to donation, and most respondents were satisfied with the experience. The main criticisms related to hotel services, the duration of the preoperative investigations, the perceived quality of nursing care on the general wards, medical communication and the duration of postoperative follow up. The self-reported time to meet recovery goals was extremely broad. Considering the nature of criticisms offered by the respondents, it is concluded that the expectations of donors as health-care consumers will only be met through modification of existing protocols.

Blood safety and sufficiency are major challenges in Kenya and other sub-Saharan African countries forcing many countries to rely on family replacement donors (FRD). We analysed data from a national AIDS indicator survey to describe blood donors in Kenya and potential risks of transfusion transmissible infections (TTI) comparing voluntary donors and FRD. A population-based, cross-sectional survey was conducted in 2007 among 15- to 64-year-olds. Consenting participants were interviewed about blood donation history and were tested for HIV, HSV-2 and syphilis. Of the 17,940 people surveyed, 445 (2·3%) reported donating blood in the prior 12 months. Sixty-four per cent were voluntary donors, and the rest were FRD. Compared to FRD, the majority of voluntary donors were <25 years old (59% versus 18%), from the highest wealth quintile (57% versus 42%) and single (64% versus 23%). In addition, voluntary donors were less likely to have been sexually active than replacement donors (43% versus 13%). HIV prevalence was lower among voluntary donors than among FRD (2·6% versus 7·4%, P-value=0·07). The majority of blood donors in Kenya are voluntary with lower potential risk of TTI. © 2010 The Author(s). Vox Sanguinis © 2010 International Society of Blood Transfusion.

Embryo donation parents' attitudes towards donors: comparison with adoption.

MacCallum, Fiona

2009-03-01

Embryo donation produces a family structure where neither rearing parent is genetically related to the child, as in adoption. It is not known how embryo donation parents view the donors compared with how adoptive parents view the birth parents. 21 couples with an embryo donation child aged 2-5 years were compared with 28 couples with an adopted child. Parents were administered a semi-structured interview, assessing knowledge of the donors/birth parents, frequency of thoughts and discussions about the donors/birth parents and disclosure of the donor conception/adoption to the child. Comparisons were made between mothers and fathers to examine gender differences. Embryo donation parents generally knew only the donors' physical characteristics, and thought about and talked about the donors less frequently than adoptive parents thought about and talked about the birth parents. Embryo donation fathers tended to think about the donors less often than did mothers. Disclosure of the child's origins in embryo donation families was far less common than in adoptive families (P < 0.001 for mothers and fathers), and was associated with the level of donor information (P < 0.05 for mothers, P < 0.025 for fathers). Embryo donation parents' views on the donors differ from adoptive parents' views on the birth parents, with donors having little significance in family life once treatment is successful.

Nucleic acid testing (NAT) for hepatitis C virus (HCV) is recommended for screening of organ donors, yet not all donor infections may be detected. We describe three US clusters of HCV transmission from donors at increased risk for HCV infection. Donor's and recipients' medical records were reviewed. Newly infected recipients were interviewed. Donor-derived HCV infection was considered when infection was newly detected after transplantation in recipients of organs from increased risk donors. Stored donor sera and tissue samples were tested for HCV RNA with high-sensitivity quantitative PCR. Posttransplant and pretransplant recipient sera were tested for HCV RNA. Quasispecies analysis of hypervariable region-1 was used to establish genetic relatedness of recipient HCV variants. Each donor had evidence of injection drug use preceding death. Of 12 recipients, 8 were HCV-infected-6 were newly diagnosed posttransplant. HCV RNA was retrospectively detected in stored samples from donor immunologic tissue collected at organ procurement. Phylogenetic analysis showed two clusters of closely related HCV variants from recipients. These investigations identified the first known HCV transmissions from increased risk organ donors with negative NAT screening, indicating very recent donor infection. Recipient informed consent and posttransplant screening for blood-borne pathogens are essential when considering increased risk donors. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

Donor, dad, or…? Young adults with lesbian parents' experiences with known donors.

PubMed

Goldberg, Abbie E; Allen, Katherine R

2013-06-01

In this exploratory qualitative study of 11 young adults, ages 19-29 years, we examine how young people who were raised by lesbian parents make meaning out of and construct their relationships with known donors. In-depth interviews were conducted to examine how participants defined their family composition, how they perceived the role of their donors in their lives, and how they negotiated their relationships with their donors. Findings indicate that mothers typically chose known donors who were family friends, that the majority of participants always knew who their donors were, and that their contact with donors ranged from minimal to involved. Further, participants perceived their donors in one of three ways: as strictly donors and not members of their family; as extended family members but not as parents; and as fathers. The more limited role of donors in participants' construction of family relationships sheds light on how children raised in lesbian, gay, and bisexual families are contributing to the redefinition and reconstruction of complex kinship arrangements. Our findings hold implications for clinicians who work with lesbian-mother families, and suggest that young adulthood is an important developmental phase during which interest in and contact with the donor may shift, warranting a transfer of responsibility from mother to offspring in terms of managing the donor-child relationship. © FPI, Inc.

Civil society advocacy in Nigeria: promoting democratic norms or donor demands?

PubMed

Williamson, R Taylor; Rodd, Joshua

2016-07-11

Civil society organizations (CSOs) are often assumed to be institutions that facilitate communication between citizens and policymakers. However, CSO advocacy is only as effective as the space allowed by government, the resources available from funders, and their own internal capacity. This article presents findings from a study in Nigeria that explores the advocacy and service delivery roles of CSOs working in Human Immunodeficiency Virus (HIV) prevention and mitigation. We will argue that donor and government treatment of civil society as service delivery organizations, rather than as organizations that participate in democratic norms, have shaped how civil society organizations work to mitigate and prevent HIV. From February to April 2012, a team of Health Systems 20/20 staff and one consultant conducted 48 in-depth interviews with civil society organizations, State AIDS Control Agencies (SACAs), donors, international organizations, and networks of people living with HIV to examine a wide range of advocacy efforts by CSOs. For quantitative data collection, sampling frames were assembled from lists of HIV-oriented or involved CSOs. This sampling frame consisted of 2548 CSOs from all 36 states and the Federal Capital Territory. A random sample was then taken from the sampling frame, and we contacted 665 CSOs to arrange interviews. With a response rate of 80.2 %, the project conducted 533 surveys in February 2012. These surveys showed that CSOs advocacy efforts focused on community mobilization related to behavior change, such as peer education (54.9 % of CSOs) and rallies (58.2 % of CSOs), and not on changing government policies. In-depth interviews highlighted the role of donors and government in shaping a purely apolitical role for most CSOs through funding constraints, regulations, and capacity development choices. In light of these findings, we present key points for considering the influence of donors and government on civil society advocacy for HIV services and rights. We present evidence that donors, and international organizations, conceive of civil society as apolitical, and not as independent actors that compete for political space. More democratic and rights-based views of civil society's role, such as holding government accountable for providing services or promoting policy change, are not emphasized.

This study introduced the modified version of the Organ Transplantation Coordinator course including simulated donor family encounters (SDFEs) and communication skills. It also evaluated participants' opinions and achievement levels, and how they implemented what they learned in the course in their work settings. The course used the modified Analysis, Design, Development, Implementation, and Evaluation model and was evaluated in 3 steps. The participants' views were obtained using the course overall evaluation form and communication skills evaluation form, their success was assessed with the posttest and SDFEs evaluation form, and the effects of what they learned during the course on their work settings were assessed through telephone interviews. At this step, the participants were asked to write letters about the targets they intended to achieve in their work settings. The letters were analyzed with the content analysis method, and a questionnaire consisting of 105 targets was developed. A year later the participants were telephoned and asked to what extent they achieved their targets. The participants' satisfaction from the whole course was high (x: 8.65 ± 1.06). In the communication skills evaluation form, the participants stated that they would mainly utilize their communication and empathy skills during donor family encounters. The participants' mean posttest score was high (x: 96.0 ± 3.8). During the SDFEs, 70% of the respondents' performance was considered sufficient. Telephone interviews conducted with the questionnaire revealed that 77.6% of the targets were fulfilled. It can be said that the course affected the participants in terms of implementing their knowledge and communication skills related to family encounters. Copyright © 2015 Elsevier Inc.

2017-01-01

Objectives: Including or excluding certain questions about organ donation may influence peoples’ intention to donate. We investigated the effect of omitting certain affective attitudinal items on potential donors’ intention and behavior for donation. Design: A cross-sectional survey with a subgroup nested randomized trial. Methods: A total of 578 members of the public in four shopping centers were surveyed on their attitudes to organ donation. Non-donors (n = 349) were randomly assigned to one of three groups: Group 1 completed items on affective and cognitive attitudes, anticipated regret, intention, subjective norm and perceived behavioral control. Group 2 completed all items above but excluded affective attitudes. Group 3 completed all items but omitted negatively worded affective attitudes. The primary outcome was intention to donate, taking a donor card after the interview was a secondary behavioral outcome, and both were predicted using linear and logistic regression with group 1 as the reference. Results: Mean (SD) 1–7 intention scores for groups 1, 2 and 3 were, respectively: 4.43 (SD 1.89), 4.95 (SD 1.64) and 4.88 (SD 1.81), with group 2 significantly higher than group 1 (β = 0.518, 95% confidence interval [CI] 0.18 to 0.86).At the end of the interview, people in group 2 (66.7%; OR = 1.40, 95% CI 0.94 to 2.07, p = 0.096) but not those in group 3 (61.7%; OR = 1.10, 95% CI 0.69 to 1.75, p = 0.685), were marginally more likely to accept a donor card from the interviewer than people in group 1 (59.7%). Conclusion: Omitting affective attitudinal items results in higher intention to donate organs and marginally higher rates of acceptance of donor cards, which has important implications for future organ donation public health campaigns.

"In the driver's seat": the Health Sector Strategic Master Plan as an instrument for aid coordination in Mongolia.

In 2005, the Ministry of Health (MoH) in Mongolia initiated the process of developing its Health Sector Strategic Master Plan (HSSMP), using a wide-ranging consultative process, driven by the MoH, and requiring participation from all levels of health facilities, other ministries, donor agencies and NGOs. Among other objectives, the MoH sought to coordinate the disparate inputs from key donors through the HSSMP, aligning them with the Plan's structure. This research explores the extent to which the HSSMP process served as a mechanism for effective aid coordination while promoting ownership and capacity building and the lessons learned for the wider international development community. The study is based on document review, key-informant interviews and authors' experience and participation in the MoH planning processes. The HSSMP process improved alignment and harmonisation. It enabled a better local understanding of the benefits of aid coordination, and the recognition that aid coordination as not only a mere administrative task, but a strategic step towards comprehensive management of both domestic and external resources. The process was not challenge free; the fractious political environment, the frequent turnover of key MoH staff, the resistance of some donors towards MoH scrutiny over their programmes and the dismantling of the central coordination and return of seconded staff following completion of the HSSMP, has slowed the pace of reform. Despite the challenges, the approach resulted in positive outcomes in the areas of ownership and better aid coordination, with HSSMP development emphasising ownership and capacity building. This contrasted with the usual outcomes focus, and neglect of the capacity building learning processes and structural and policy changes needed to ensure sustainable change. The largest and most influential programmes in the health sector are now largely aligned with HSSMP strategies, enabling the MoH to utilize these opportunities to optimise the HSSMP outcomes. The lessons for Ministries of Health in similar Post-Soviet countries--or other emerging economies where government capacity and local policy processes are relatively strong--are clear: the development of solid governance and technical infrastructure in terms of planning and evaluation provide a solid structure for donor coordination and insure against local political change.

Mistrust, misperceptions, and miscommunication: a qualitative study of preferences about kidney transplantation among African Americans.

2015-03-01

Kidney transplantation rates in the United States are lower among African Americans than among whites. Well-documented racial disparities in access to transplantation explain some, but not all, of these differences. Prior survey-based research suggests that African American dialysis patients are less likely than whites to desire transplantation, but little research has focused on an in-depth exploration of preferences about kidney transplantation among African Americans. Thus, the purposes of this study were to explore preferences and to compare patients' expectations about transplantation with actual status on the transplant list. We conducted semistructured interviews with 16 African Americans receiving chronic hemodialysis. We analyzed the interviews using the constant comparative method of qualitative analysis. We also reviewed the dialysis center's transplant list. Four dominant themes emerged: (1) varied desire for transplant; (2) concerns about donor source; (3) barriers to transplantation; and (4) lack of communication with nephrologists and the transplantation team. A thread of mistrust about equity in the transplantation process flowed through themes 2-4. In 7/16 cases, patients' understanding of their transplant listing status was discordant with their actual status. Our study suggests that many African Americans on hemodialysis are interested in kidney transplantation, but that interest is often tempered by concerns about transplantation, including misconceptions about the risks to recipients and donors. Mistrust about equity in the organ allocation process also contributed to ambivalence. The discordance between patients' perceptions of listing status and actual status suggests communication gaps between African American hemodialysis patients and physicians. Clinicians should avoid interpreting ambivalence about transplantation as lack of interest. Published by Elsevier Inc.

Various reasons may guide the decision of men to become a sperm donor. Our aim was to identify a comprehensive set of possible reasons for and against sperm donation. Concept mapping. Assisted reproduction clinics. Nine sperm donors and seven non-sperm donors. Interviews to obtain statements for and against sperm donation, card-sorting tasks to categorize these statements according to similarity, and hierarchical cluster analysis to structure these categorizations. Hierarchical structure with reasons for and against sperm donation. The hierarchical structure with 91 reasons comprised selfishness (including narcissism and procreation), psychosocial drives (including altruism, detached procreation, and sexual/financial satisfaction), and psychosocial barriers (including normative and moral barriers related to oneself, one's spouse, the donor child, and society). The identified hierarchical overview of reasons for and against sperm donation may help potential sperm donors when considering becoming a sperm donor, enable more systematic counseling of potential sperm donors, and guide further research on reasons for and against sperm donation. © 2013 The Authors Acta Obstetricia et Gynecologica Scandinavica © 2013 Nordic Federation of Societies of Obstetrics and Gynecology.

Background Although risk factors for HIV infection are known, it is important for blood centers to understand local epidemiology and disease transmission patterns. Current risk factors for HIV infection in blood donors in Brazil were assessed. Methods A case-control study was conducted at large public blood centers located in four major cities between April 2009 – March 2011. Cases were persons whose donations were confirmed positive by enzyme immunoassays followed by Western Blot confirmation. Audio computer-assisted structured-interviews (ACASI) were completed by all cases and controls. Multivariable logistic regression was used to estimate adjusted odds ratios (AORs) and associated 95% confidence intervals (CIs). Results There were 341 cases, including 47 with recently-acquired infection, and 791 controls. Disclosed risk factors for both females and males were sex with an HIV-positive person (adjusted odds ratio (AOR) 11.3, 95% CI [4.1, 31.7]) and being an IVDU or sexual partner of an IVDU (AOR 4.65 [1.8, 11.7]). For female blood donors, additional risk factors were having male sex partners who also are MSM (AOR 13.5 [3.1, 59.8]), and having unprotected sex with multiple sexual partners (AOR 5.19 [2.1, 12.9]). The primary risk factor for male blood donors was MSM activity (AOR 21.6 [8.8, 52.9.]). Behaviors associated with recently-acquired HIV were being a MSM or sex partner of MSM (13.82, [4.7, 40.3]), and IVDU (11.47, [3.0, 43.2]). Conclusion Risk factors in blood donors parallel those in the general population in Brazil. Identified risk factors suggest that donor compliance with selection procedures at the participating blood centers is inadequate. PMID:23517235

The shortage of sperm donors in formal settings (i.e., assisted reproduction clinics) and the availability of sperm donors in informal settings (such as through contacts on the internet) motivated us to investigate why men may prefer either a formal or an informal setting for sperm donation. Interviews with ten sperm donors and non-sperm donors yielded 55 reasons for sperm donation in the two settings. These reasons were categorized according to similarity by 14 sperm donors and non-sperm donors. These categorizations were then structured by means of hierarchical cluster analysis. Reasons favouring formal settings included being legally and physically protected, evading paternal feelings or social consequences, and having a simple, standardized procedure in terms of effort and finances. Reasons favouring informal settings related to engagement, the possibility to choose a recipient, lack of rules and regulations, having contact with the donor child, and having an (intimate) bond with the recipient. The overview of reasons identified may help potential sperm donors decide on whether to donate in a formal or informal setting, and may fuel discussions by professionals about the most appropriate conditions and legislation for sperm donation in formal settings.

As results from single center (mostly kidney) donor studies demonstrate interpersonal relationship and financial strains for some donors, we conducted a liver donor study involving nine centers within the A2ALL-2 Consortium. Among other initiatives A2ALL-2 examined the nature of these outcomes following donation. Using validated measures, donors were prospectively surveyed pre-donation, and 3, 6, 12, and 24 months post-donation. Repeated measures regression models were used to examine social relationship and financial outcomes over time and identify relevant predictors. Of 297 eligible donors, 271 (91%) consented and were interviewed at least once. Relationship changes were overall positive across post-donation time points, with nearly one-third reporting improved donor family and spousal/partner relationships and >50% reporting improved recipient relationships. However, the majority of donors reported cumulative out-of-pocket medical and non-medical expenses, which were judged burdensome by 44% of donors. Lower income predicted burdensome donation costs. Those who anticipated financial concerns and who held non-professional positions before donation were more likely to experience adverse financial outcomes. These data support the need for initiatives to reduce financial burden. PMID:27647626

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

African Americans are disproportionately affected by ESRD, but few receive a living donor kidney transplant. Surveys assessing attitudes toward donation have shown that African Americans are less likely to express a willingness to donate their own organs. Studies aimed at understanding factors that may facilitate the willingness of African Americans to become organ donors are needed. A novel formative research method was used (the nominal group technique) to identify and prioritize strategies for facilitating increases in organ donation among church-attending African Americans. Four nominal group technique panel interviews were convened (three community and one clergy). Each community panel represented a distinct local church; the clergy panel represented five distinct faith-based denominations. Before nominal group technique interviews, participants completed a questionnaire that assessed willingness to become a donor; 28 African-American adults (≥19 years old) participated in the study. In total, 66.7% of participants identified knowledge- or education-related strategies as most important strategies in facilitating willingness to become an organ donor, a view that was even more pronounced among clergy. Three of four nominal group technique panels rated a knowledge-based strategy as the most important and included strategies, such as information on donor involvement and donation-related risks; 29.6% of participants indicated that they disagreed with deceased donation, and 37% of participants disagreed with living donation. Community participants' reservations about becoming an organ donor were similar for living (38.1%) and deceased (33.4%) donation; in contrast, clergy participants were more likely to express reservations about living donation (33.3% versus 16.7%). These data indicate a greater opposition to living donation compared with donation after one's death among African Americans and suggest that improving knowledge about organ donation, particularly with regard to donor involvement and donation-related risks, may facilitate increases in organ donation. Existing educational campaigns may fall short of meeting information needs of African Americans. Copyright © 2015 by the American Society of Nephrology.

Beyond motivation: on what it means to be a sperm donor in Denmark

PubMed Central

Mohr, Sebastian

2014-01-01

This paper, analyzing interviews with men that donate their semen in Denmark, explores what it means to be a sperm donor. Breaking with the assumption that men have a specific and clearly identifiable motivation to become sperm donors, this paper leaves the confinement of such an accountable actor model implied in asking for men's motivations to donate semen. Instead, the author describes the experiences of sperm donors to show how the moral, organizational, and biomedical-technological context of sperm donation in Denmark makes for enactments of moral selves as well as specific embodiments of masculinity. Instead of looking for motivations that can be accounted for, the author engages with the question of how donating semen affords men the experience of moral and gendered selves. PMID:25175292

Commentators are concerned that broad consent may not provide biospecimen donors with sufficient information regarding possible future research uses of their tissue. We surveyed with interviews 302 cancer patients who had recently provided broad consent at four diverse academic medical centers. The majority of donors believed that the consent form provided them with sufficient information regarding future possible uses of their biospecimens. Donors expressed very positive views regarding tissue donation in general and endorsed the use of their biospecimens in future research across a wide range of contexts. Concerns regarding future uses were limited to for-profit research and research by investigators in other countries. These results support the use of broad consent to store and use biological samples in future research.

Allogenic hematopoietic stem cell transplantation is a curative treatment for patients with advanced hematologic malignancies. However, the long-term mental health issues of siblings who were not selected as donors (non-donor siblings, NDS) in the transplantation have not been well assessed. Data mining is useful in discovering new findings from a large, multidisciplinary data set and the Scenario Map analysis is a novel approach which allows extracting keywords linking different conditions/events from text data of interviews even when the keywords appeared infrequently. The aim of this study is to assess mental health issues on NDSs and to find helpful keywords for the clinical follow-up using a Scenario Map analysis. A 47-year-old woman whose younger sister had undergone allogenic hematopoietic stem cell transplantation 20 years earlier was interviewed as a NDS. The text data from the interview transcriptions was analyzed using Scenario Mapping. Four clusters of words and six keywords were identified. Upon review of the word clusters and keywords, both the subject and researchers noticed that the subject has had mental health issues since the disease onset to date with being a NDS. The issues have been alleviated by her family. This single subject study suggested the advantages of data mining in clinical follow-up for mental health issues of patients and/or their families.

Toxic money or paid altruism: the meaning of payments for identity-release gamete donors.

PubMed

Gilman, Leah

2018-05-01

Public discourses commonly frame gamete, organ and other forms of bodily donation as altruistic 'gifts'. However, despite on-going debates about the ethics of payments to donors, few studies have examined the views of donors themselves regarding the meaning of payments and their compatibility (or not) with understandings of these practices as gifts. This article addresses this issue, analysing 24 in-depth interviews with UK identity-release gamete donors. It was crucial to all participants that their donation be viewed as fundamentally other-oriented, motivated by the desire to help others. However, whilst egg donors often accommodated payment within this narrative, male participants explained that any money would taint the gift they had given. I argue that sperm donors faced particular challenges to incorporating payment within a gift narrative for two key reasons: first, sperm donors relied on a discourse of 'pure altruism', including absolute opposition between gifts and market exchange, in order to present their donation as other-oriented. In contrast, egg donors were also able to mobilise a discourse of relational giving to present their donations as a personal gift. Second, according to a continued stereotype of sperm donors as financially motivated students, their payments have already been culturally earmarked as side-line earnings. © 2018 Foundation for the Sociology of Health & Illness.

Hispanic Americans have a substantial need for organ transplants and are underrepresented among organ donors, yet little is known about predictors of organ donation outcomes in this population. To assess factors that may function as significant predictors of organ donation behavior among Hispanic Americans. A random-digit-dial computer-assisted telephone-interview survey. Setting-Pima and Maricopa counties in Arizona. 1200 Hispanic Americans. Family discussion of organ donation and willingness to be an organ donor. Significant predictors of family discussion of organ donation include knowing someone willing to be an organ donor and disagreeing that carrying a donor card results in inadequate medical care. Willingness to be a donor is also predictive of family discussion. Significant predictors of willingness to be an organ donor are knowing someone willing to be an organ donor, being female, and disagreeing that thoughts about donation leads to thoughts about one's own mortality. Having a family discussion about organ donation is also predictive of willingness to be an organ donor. The data provide a springboard for larger studies encompassing the diversity and geographical dispersion of Hispanic Americans. The data also highlight the importance of educational efforts to make Hispanic Americans aware of people in their community who have donated in the past or who are now potential donors.

Between 2000 and December 2013, 106 live donor nephrectomies from anonymous living-donors were performed at the Erasmus MC Rotterdam; five of the donors (5.4%) had a life-threatening disease. The aim of the present report is to give the rational and justification for this procedure. All five donors underwent the national standard living-donor screening procedure. Additionally, motivation to donate and psychologic stability were assessed by a psychologist using in-depth interview techniques and a psychologic complaints questionnaire. Post-donor nephrectomy follow-up consisted of standard questionnaires and clinical check-ups. One patient had cerebral and caudal ependymomas, one had severe and progressive emphysema, two had Huntington's disease and one had a grade 2 oligodendroglioma. The psychologic screening revealed genuine motivation, adequate risk perception, and normal sense of reality. No contraindications for donation were found. The five donor nephrectomies made nine kidney transplantations possible. All donors were satisfied with the donation procedure. Three donors died during follow-up (0.6-4.9 years) as a result of their disease. In the absence of apparent additional health risks, medical, and psychologic contraindications, we consider it ethically justified to accept an offer from a cognitively competent patient with a life-threatening disease in view of their self-reported satisfaction during follow-up. Although based on a limited number of patients, we conclude that a stricter psychologic screening for seriously ill donors compared to healthy unspecified anonymous donors to unspecified patients is not necessary.

The study was planned to determine the presence of West Nile Virus (WNV) infection in Pakistani blood donors, using Nucleic Acid Amplification Test (NAT). The blood donors for study were selected on the basis of the standard questionnaire and routine screening results. Six donors were pooled using an automated pipettor and NAT for WNV was performed on Roche Cobas s 201 NAT system. The reactive pools were resolved in Individual Donation-NAT (ID-NAT) format and a sample from FFP bags of reactive donations was retrieved. NAT was again performed on retrieved plasma bag (RPB) sample to confirm the reactive donations. The donors were also recalled and interviewed about history of illness related to recent WNV infection. After serological screening of 1929 donors during the study period, 1860 donors were selected for NAT test for WNV detection. The mean age of the donors was 28±8.77 (range: 18-57 years). 1847 (99.3%) donors were male and 13 (0.7%) were female. NAT for WNV identified six initially reactive pools (0.32%). On follow-up testing with RPB samples, 4 donors (0.21%) were found confirmed reactive for WNV RNA (NAT yield of 1 in 465 blood donors). WNV is a threat to safety of blood products in Pakistan. A screening strategy can be implemented after a large-scale study and financial considerations. One of the reduced cost screening strategies is seasonal screening of blood donors for WNV, with pooling of samples.

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

Adult-to-adult living liver donation is associated with considerable risks with no direct medical benefit to liver donors (LDs). Ensuring that potential LDs comprehend the risks of donation is essential to medically and ethically justify the procedure. We developed and prospectively evaluated the initial psychometrics of an "Evaluation of Donor Informed Consent Tool" (EDICT) designed to assess LDs' comprehension about the living donation process. EDICT includes 49 true/false/unsure items related to LD informed consent. Consecutive LDs undergoing evaluation at 1 academic medical center from October 2012 to September 2014 were eligible for participation in pretest/posttest interviews. Medical records were reviewed for postdonation complications. Twenty-seven LDs participated (96% participation rate). EDICT demonstrated good internal consistency reliability at pretest, 2 days before donating (Cronbach's α = 0.78), and posttest, 1 week after donating (α = 0.70). EDICT scores significantly increased over time (P = 0.01) and demonstrated good test-retest reliability (r = 0.68; P < 0.001). EDICT was associated with race/ethnicity (P = 0.02) and relationship to the recipient (P = 0.01; pretest), and income (P = 0.01) and insurance (P = 0.01; posttest), but not with decisional conflict, preoperative preparedness, satisfaction, or decisional regret (pretest and posttest). Donor complications did not impact postdonation EDICT scores. In conclusion, EDICT has promising measurement properties and may be useful in the evaluation of informed consent for potential LDs. © 2015 American Association for the Study of Liver Diseases.

Anecdotal evidence suggests that missed donation appointments among repeat whole-blood donors are associated with decreased likelihood of future blood donation. This study sought to examine the relationship between missed donation appointments and intention to donate again among repeat whole-blood donors and to examine whether demographic variables are related to appointment-keeping behaviour. During the period February-June 2013, telephone interviews were conducted with repeat donors who either did not show up for or cancelled their donation appointments on the day of the appointment. We asked them whether or not they wanted to schedule appointments for subsequent donations. Rates of missed donation appointments varied by age, but not gender. Although a statistically significant difference between male and female donors was not found with regard to willingness to donate again, female donors were more likely than male donors to call and cancel their appointment. Finally, compared with repeat donors who called and cancelled their appointment, no-show donors were 2.5 times less likely to schedule appointments for subsequent donations (P < 0.001). The results demonstrate that poor appointment-keeping behaviour, and in particular no-show behaviour, is significantly associated with decreased likelihood of future blood donation among repeat whole-blood donors. © 2014 The Authors.

Because results from single-center (mostly kidney) donor studies demonstrate interpersonal relationship and financial strains for some donors, we conducted a liver donor study involving nine centers within the Adult-to-Adult Living Donor Liver Transplantation Cohort Study 2 (A2ALL-2) consortium. Among other initiatives, A2ALL-2 examined the nature of these outcomes following donation. Using validated measures, donors were prospectively surveyed before donation and at 3, 6, 12, and 24 mo after donation. Repeated-measures regression models were used to examine social relationship and financial outcomes over time and to identify relevant predictors. Of 297 eligible donors, 271 (91%) consented and were interviewed at least once. Relationship changes were positive overall across postdonation time points, with nearly one-third reporting improved donor family and spousal or partner relationships and >50% reporting improved recipient relationships. The majority of donors, however, reported cumulative out-of-pocket medical and nonmedical expenses, which were judged burdensome by 44% of donors. Lower income predicted burdensome donation costs. Those who anticipated financial concerns and who held nonprofessional positions before donation were more likely to experience adverse financial outcomes. These data support the need for initiatives to reduce financial burden. © 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

[Personality and donor-recipient relationships of potential donors before living donor liver transplantation--diagnostics with the repertory-grid technique].

2003-06-01

Living-donor liver transplantation (LDLT) is developing into an established therapy for terminal liver diseases in adults. Potential donors are faced with the risk of postoperative complications and are subject to a high level of psychological pressure and ambivalent feelings. Our assumption is that ambivalent feelings before donation are crucially influenced by the personality and the quality of the donor-recipient relationship. In highly motivated donors we expected a positive description of the recipient and a similarity in the characterisation of the donor and recipient. 58 potential living donors were evaluated between March 2000 and June 2001. On the basis of the clinical interview 10 were rated as unsuited for donation. Among those potential donors assessed as unsuited, we found a high level of ambivalent feelings. For 50 potential donors we gained a set of completed psychometric diagnostic questionnaires. A Repertory-grid investigation was conducted with a total of 28 potential donors. Seven of them were not recommended as living donors. The relationship between donors and recipients was analysed concerning constructs that were most important to the characterisation of the donor or recipient. By means of inter-element distances self-concept of donors and donor-recipient relation were analysed. Ambivalent candidates who were not recommended as living donors tended to describe the recipient negatively (selfish, carping, and unable to take criticism) and did not show a similarity in the characterisations of self and ideal-self. Whereas the highly motivated candidates were marked by a closeness of self and ideal-self concepts. Both groups saw the recipient as indifferent. Closeness between self and ideal-self-indicating satisfaction with the decision to donate seems to be one suitable criterion to distinguish between highly motivated potential donors on the one hand and ambivalent candidates on the other hand. Another criterion appears to be a description of the recipient that indicates either a functioning or ill-functioning communication between donor and recipient with respect to the donation.

Quality control (QC) data collected by blood services are used to monitor production and to ensure compliance with regulatory standards. We demonstrate how analysis of quality control data can be used to highlight the sources of variability within red cell concentrates (RCCs). We merged Canadian Blood Services QC data with manufacturing and donor records for 28 227 RCC between June 2011 and October 2014. Units were categorized based on processing method, bag manufacturer, donor age and donor sex, then assessed based on product characteristics: haemolysis and haemoglobin levels, unit volume, leucocyte count and haematocrit. Buffy-coat method (top/bottom)-processed units exhibited lower haemolysis than units processed using the whole-blood filtration method (top/top). Units from female donors exhibited lower haemolysis than male donations. Processing method influenced unit volume and the ratio of additive solution to residual plasma. Stored red blood cell characteristics are influenced by prestorage processing and donor factors. Understanding the relationship between processing, donors and RCC quality will help blood services to ensure the safety of transfused products. © 2016 International Society of Blood Transfusion.

To get acquainted about the life lessons of people who accepted donating an organ of a deceased family member. Qualitative research, in depth interviews to eight families that accepted donating an organ of a deceased family member. The interviews were analyzed using the method proposed by Streubert et al and modified by Rivera. The life lessons are described in six comprehensive categories. The painful experience changed towards the feeling that the loved one remains alive. This sensation generated a sense of pride in family members and sensitized them towards the painful experience of other people. Therefore, a desire to help and improve as humans beings was awakened. A compassionate approach towards families donating organs with improve organ donation and humanize the process.

A thorough donor evaluation in the living donation process is mandatory to ensure a safe outcome in an otherwise healthy individual. The aim of the current study was to evaluate the reasons for not proceeding to donation and the outcome of live liver donors. A prospective study of potential donors who underwent evaluation and proceeded to surgery from 1 April 2012 to 31 January 2015 was conducted. The process of donor selection, its outcome and peri-operative complications were recorded. A total of 460 donors were evaluated in a stepwise manner for 367 potential recipients. Of the 321 (69.7 %) donors not proceeding to donation, the reasons were donor-related in 63.6 % and recipient-related in the rest. Common donor-related reasons were: donor reluctance (23.5 %), negative liver attenuation index (16.2 %), anatomic variations (10.3 %), inadequate remnant liver volume (9.8 %), unacceptable liver biopsy (8.8 %), and inadequate graft volume (5.4 %). A majority of donors (82.8 %) were turned down early in the (steps 1 and 2) evaluation process. Recipient death was the most common recipient-related reason [n = 51 (43.6 %)] for not proceeding to donation. There was no donor mortality. The overall complication rate was 19.8 % and major complication rate (grade 3 or higher) was 4.4 %. A stringent stepwise donor evaluation process leads to early recognition of unsuitable donors and a low complication rate.

To increase the donor pool, the strategy of transplantation from "marginal" donors was developed though patients' preferences about these donors were insufficiently known. The preferences of patients registered on the waiting list or already transplanted in eight transplant teams covering four main organs (i.e., kidney, liver, heart, and lung) were evaluated using the discrete choice experiment method. In each left during 2 days, patients were interviewed on four scenarios. Of 178 eligible patients, 167 were interviewed; 40% accepted marginal graft in their own situation and 89% at least in one of the scenarios. Imagining urgent situations or rare profiles with difficult access to transplantation, respectively, 86% and 71% accepted these grafts. Most (76%) preferred to be informed about these grafts and 43% preferred to be involved in decision. The emergency [OR = 1.24; 95% CI: (1.06-1.45)] and the hazardousness [OR = 0.88; 95% CI: (0.78-0.99)] of the transplantation were factors independently associated with marginal graft acceptance. Most patients preferred to be informed and to be involved in the decision. Marginal grafts could be more accepted by patients in critical medical situations or perceiving their situation as critical. Physicians' practices in transplantation should be reconsidered taking into account individual preferences. This study was performed in a single country and thus reflects the cultural bias and practice thereof. © 2017 Steunstichting ESOT.

Can evidence-based health policy from high-income countries be applied to lower-income countries: considering barriers and facilitators to an organ donor registry in Mumbai, India.

PubMed

Vania, Diana K; Randall, Glen E

Organ transplantation has become an effective means to extend lives; however, a major obstacle is the lack of availability of cadaveric organs. India has one of the lowest cadaver organ donation rates in the world. If India could increase the donor rate, the demand for many organs could be met. Evidence from high-income countries suggests that an organ donor registry can be a valuable tool for increasing donor rates. The purpose of this study is to determine whether the implementation of an organ donor registry is a feasible and appropriate policy option to enhance cadaver organ donation rates in a lower-income country. This qualitative policy analysis employs semi-structured interviews with physicians, transplant coordinators, and representatives of organ donation advocacy groups in Mumbai. Interviews were designed to better understand current organ donation procedures and explore key informants' perceptions about Indian government health priorities and the likelihood of an organ donor registry in Mumbai. The 3-i framework (ideas, interests, and institutions) is used to examine how government decisions surrounding organ donation policies are shaped. Findings indicate that organ donation in India is a complex issue due to low public awareness, misperceptions of religious doctrines, the need for family consent, and a nation-wide focus on disease control. Key informants cite social, political, and infrastructural barriers to the implementation of an organ donor registry, including widely held myths about organ donation, competing health priorities, and limited hospital infrastructure. At present, both the central government and Maharashtra state government struggle to balance international pressures to improve overall population health with the desire to also enhance individual health. Implementing an organ donor registry in Mumbai is not a feasible or appropriate policy option in India's current political and social environment, as the barriers, identified through the 3-i framework lens, may be too difficult to overcome. Despite the evidence supporting the use of donor registries as a means to enhance organ donation rates, it is clear that context is critical and that it is not always practical to apply evidence-based policy solutions from high-income countries to lower-income settings.

The effect of whole-blood donor adverse events on blood donor return rates.

Some blood donation-related adverse events (AEs) can negatively impact the blood donor return rate (BDRR) and decrease donor retention. One-thousand randomly selected whole-blood donors were interviewed 3 weeks after a 525-mL index whole-blood donation for seven AEs. The number of return visits and duration of follow-up were recorded for each of the 1000 donors. A negative binomial regression analysis was used to determine the contribution of the four most common AEs to the BDRR, and interactions between these AEs were also evaluated. The four most common AEs were bruise alone (15.1%), sore arm "alone" (7.0%), fatigue "alone" (5.1%), and donor reaction "alone" (4.2%), where "alone" is defined to also include donors who had a bruise but no other AE. The estimated BDRR for donations without AEs was 1.32 visits per year. The estimated BDRRs for the four most common AEs were: bruise alone, 1.32 visits per year; sore arm alone, 1.30 visits per year (2% reduction in BDRR); fatigue alone, 1.06 visits per year (20% reduction in BDRR); and donor reaction alone, 0.87 visits per year (34% reduction in BDRR). The BDRR for donor reaction, fatigue, and sore arm together was 0.20 visits per year (85% reduction in BDRR). Donor reaction had the most negative impact on the BDRR. There appears to be a synergistic effect between donor reaction, fatigue, and sore arm. Theoretically, amelioration of some AEs has the potential to improve BDRRs.

Little is known about living liver donors' perceptions of their physical well-being following the procedure. We collected data on donor fatigue, pain, and other relevant physical outcomes as part of the prospective, multi-center Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL-2) Consortium. A total of 271 (91%) of 297 eligible donors were interviewed at least once at pre-donation and 3, 6, 12, and 24 months after donation using validated measures, when available. Repeated measures regression models were used to identify potential predictors of worse physical outcomes. We found that donors reported more fatigue immediately after surgery that were returning to pre-donation levels by two years post-donation. A similar pattern was seen across a number of other physical outcomes. Abdominal or back pain and interference from their pain were rated relatively low on average at all study points. However, 21% of donors did report clinically significant pain at some point during post-donation study follow-up. Across multiple outcomes, female donors, donors whose recipients died, donors with longer hospital stays after surgery, and those whose families discouraged donation were at risk for worse physical well-being outcomes. While not readily modifiable, we have identified risk factors that may help identify donors at risk for worse physical outcomes for targeted intervention. This article is protected by copyright.

Adhesive retention dressings are more comfortable than alginate dressings on split-skin-graft donor sites.

PubMed

Hormbrey, E; Pandya, A; Giele, H

2003-07-01

Painful split-skin-graft donor sites remain a common problem for patients. We undertook a prospective randomised trial to examine the comparative comfort and ease of care of two different donor-site dressings. One dressing is the alginate Kaltostat, the standard plastic-surgical dressing in the UK and abroad, and the other is the adhesive retention tape Mefix, a novel use of a readily available dressing. We randomised 50 patients requiring split-skin grafts to receive either alginate (Kaltostat) or retention (Mefix) donor-site dressings. Dressings were assessed by interview and questionnaire at 24, 72 h and 2 weeks, and by wound review at 2 weeks. Retention dressings were found to be more comfortable, required less nursing intervention and allowed patients easier mobility with a greater range of daily activities, especially washing, without compromising wound healing. We recommend adhesive retention dressings as cost-effective comfortable dressings, which readily conform to any donor site.

'It's a regional thing': financial impact of renal transplantation on live donors.

PubMed

McGrath, Pam; Holewa, Hamish

2012-01-01

There has been no research exploring the financial impact on the live renal donor in terms of testing, hospitalisation and surgery for kidney removal (known as nephrectomy). The only mention of financial issues in relation to live renal transplantation is the recipients' concerns in relation to monetary payment for the gift of a kidney and the recipients' desire to pay for the costs associated with the nephrectomy. The discussion in this article posits a new direction in live renal donor research; that of understanding the financial impact of live renal donation on the donor to inform health policy and supportive care service delivery. The findings have specific relevance for live renal donors living in rural and remote locations of Australia. The findings are presented from the first interview (time 1: T1) of a set of four times (time 1 to time 4: T1-T4) from a longitudinal study that explored the experience of live renal donors who were undergoing kidney removal (nephrectomy) at the Renal Transplantation Unit at the Princess Alexandra Hospital, Brisbane, Australia. A qualitative methodological approach was used that involved semi-structured interviews with prospective living kidney donors (n=20). The resulting data were analysed using the qualitative research methods of coding and thematic analysis. The findings indicate that live renal donors in non-metropolitan areas report significant financial concerns in relation to testing, hospitalisation and surgery for nephrectomy. These include the fact that bulk billing (no cost to the patient for practitioner's service) is not always available, that individuals have to pay up-front and that free testing at local public hospitals is not available in some areas. In addition, non-metropolitan donors have to fund the extra cost of travel and accommodation when relocating for the nephrectomy to the specialist metropolitan hospital. Live renal transplantation is an important new direction in medical care that has excellent long-term results for individuals diagnosed with end-stage renal disease. An essential element of the transplantation procedure is the voluntary donation of a healthy kidney by the live renal donor. Such an altruistic gift, which has no personal health benefit for the donor, is to be applauded and supported. The present research demonstrates that for some donors, particularly those living outside the metropolitan area, the gift may also include a range of financial costs to the donor. There is no prior research available on the financial impact of live renal donation for individuals living in non-metropolitan areas. Thus, this article is a seminal work in the area. The findings affirm 'rural disadvantage' by demonstrating that it is the live renal donors in non-metropolitan areas who are reporting financial concerns in relation to testing, hospitalisation and surgery for nephrectomy. It is the hope and expectation that the reporting on these costs will encourage further work in this area and the findings will be used for health policy and service delivery considerations.

Bioethics and power: Informed consent procedures in post-socialist Latvia.

PubMed

Putniņa, Aivita

2013-12-01

This paper explores two lines of development in the donor consent procedures in post-Soviet Latvia. The paper is based on secondary analysis of interview, focus group discussion data, and media and legal text material collected throughout three previously conducted research projects on organ transplantation, population genome project and xenotransplantation focusing on the historical development of the issues of donor consent across these three fields of medical technologies. The paper argues that the quality of consent depends not as much on political and legal change per se as on the strengthening of the position of both medical specialists and donors, facilitating bonds between the two.

BACKGROUND: Process Excellence is a value based approach and focuses on standardizing work processes by eliminating the non-value added processes, identify process improving methodologies and maximize capacity and expertise of the staff. AIM AND OBJECTIVES: To Evaluate the utility of Process Excellence Tools in improving Donor Flow Management in a Tertiary care Hospital by studying the current state of donor movement within the blood bank and providing recommendations for eliminating the wait times and to improve the process and workflow. MATERIALS AND METHODS: The work was done in two phases; The First Phase comprised of on-site observations with the help of an expert trained in Process Excellence Methodology who observed and documented various aspects of donor flow, donor turn around time, total staff details and operator process flow. The Second Phase comprised of constitution of a Team to analyse the data collected. The analyzed data along with the recommendations were presented before an expert hospital committee and the management. RESULTS: Our analysis put forward our strengths and identified potential problems. Donor wait time was reduced by 50% after lean due to better donor management with reorganization of the infrastructure of the donor area. Receptionist tracking showed that 62% of the total time the staff wastes in walking and 22% in other non-value added activities. Defining Duties for each staff reduced the time spent by them in non-value added activities. Implementation of the token system, generation of unique identification code for donors and bar code labeling of the tubes and bags are among the other recommendations. CONCLUSION: Process Excellence is not a programme; it's a culture that transforms an organization and improves its Quality and Efficiency through new attitudes, elimination of wastes and reduction in costs.

Donor Conception and "Passing," or; Why Australian Parents of Donor-Conceived Children Want Donors Who Look Like Them.

PubMed

Wong, Karen-Anne

2017-03-01

This article explores the processes through which Australian recipients select unknown donors for use in assisted reproductive technologies and speculates on how those processes may affect the future life of the donor-conceived person. I will suggest that trust is an integral part of the exchange between donors, recipients, and gamete agencies in donor conception and heavily informs concepts of relatedness, race, ethnicity, kinship, class, and visibility. The decision to be transparent (or not) about a child's genetic parentage affects recipient parents' choices of donor, about who is allowed to "know" children's genetic backgrounds, and how important it is to be able to "pass" as an unassisted conception. In this way, recipients must trust the process, institutions, and individuals involved in their treatment, as well as place trust in the future they imagine for their child. The current market for donor gametes reproduces normative conceptions of the nuclear family, kinship, and relatedness by facilitating "matching" donors to recipients by phenotype and cultural affinities. Recipient parents who choose not to prioritize "matching," and actively disclose the process of children's conceptions, may embark on a project of queering heteronormative family structures and place great trust in both their own children and changing social attitudes to reduce stigma and generate acceptance for non-traditional families.

To identify risk factors for suboptimal IVF outcomes using insemination with donor spermatozoa and to define a lower threshold that may signal a conversion to fertilization by ICSI rather than insemination. Retrospective, age-matched, case-control study of women undergoing non-donor oocyte IVF cycles using either freshly ejaculated (N=138) or cryopreserved donor spermatozoa (N=69). Associations between method of fertilization, semen sample parameters, and pregnancy rates were analyzed. In vitro fertilization of oocytes with donor spermatozoa by insemination results in equivalent fertilization and pregnancy rates compared to those of freshly ejaculated spermatozoa from men with normal semen analyses when the post-processing motility is greater than or equal to 88%. IVF by insemination with donor spermatozoa when the post-processing motility is less than 88% is associated with a 5-fold reduction in pregnancy rates when compared to those of donor spermatozoa above this motility threshold. When the post-processing donor spermatozoa motility is low, fertilization by ICSI is associated with significantly higher pregnancy rates compared to those of insemination. While ICSI does not need to be categorically instituted when using donor spermatozoa in IVF, patients should be counseled that conversion from insemination to ICSI may be recommended based on low post-processing motility.

Risk factor surveillance among infected blood donors provides information on the effectiveness of eligibility assessment and is critical for reducing risk of transfusion-transmitted infection. American Red Cross, Blood Systems, Inc., New York Blood Center, and OneBlood participated in a case-control study from 2010 to 2013. Donors with serologic and nucleic acid testing (NAT) or NAT-only confirmed human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), or serology-confirmed human T-lymphotropic virus (HTLV) infections (cases) and donors with false-positive results (controls) were interviewed for putative behavioral and demographic risks. Frequencies and adjusted odds ratios (AORs) from multivariable logistic regression analyses for each exposure in cases compared to controls are reported. In the study, 196 HIV, 292 HBV, 316 HCV, and 198 HTLV cases, and 1587 controls were interviewed. For HIV, sex with an HIV+ person (AOR, 132; 95% confidence interval [CI], 27-650) and male-male sex (AOR, 62; 95% CI, 27-140) were primary risk factors. For HBV, first-time donor status (AOR, 16; 95% CI, 10-27), sex with an injection drug user (IDU; AOR, 11; 95% CI, 5-28), and black race (AOR, 11; 95% CI, 6-19) were primary. For HCV, IDU (AOR, 42; 95% CI, 13-136), first time (AOR, 18; 95% CI, 10-30), and a family member with hepatitis (AOR, 15; 95% CI, 6-40) were primary. For HTLV, sex with an IDU (AOR, 22; 95% CI, 10-48), 55 years old or more (AOR, 21; 95% CI, 8-52], and first time (AOR, 15; 95% CI, 9-24) were primary. Despite education efforts and risk screening, individuals with deferrable risks still donate; they may fail to understand or ignore or do not believe they have risk. Recipients have potential transfusion-transmitted infection risk because of nondisclosure by donors. © 2014 AABB.

The enzyme immunoassays (EIAs) for antibody to human T-cell lymphotropic virus type III (HTLV-III) were rapidly adopted for screening donated blood and plasma. To evaluate the significance of a positive EIA reaction, test performance was examined in a blood bank screening program. Specimens were tested by EIA, Western blot assay, and HTLV-III/lymphadenopathy-associated virus (LAV) culture. The EIA was positive in 0.25% of 67 190 blood donations. Specimens were categorized and 57.3% had low (weak) reactivity, 12.7% had moderate reactivity, and 30.0% had high reactivity. Highly reactive specimens were strongly associated with a positive Western blot or culture (86.7%) in contrastmore » to moderately and weekly reactive specimens (1.9%). Twenty-five of 29 donors interviewed with a highly reactive EIA had risk factors for HTLV-III/LAV infection. Risk factors were not identified for 74 of 75 interviewed donors with specimens of lower reactivity. The minimum calculated specificity was 99.82%. The use of the HTLV-III EIA has virtually eliminated the use of blood and plasma for HTLV-III/LAV infected donors.« less

Universal donor education and consent: what we know and where we should go.

PubMed

Wehrli, Gay; Sazama, Kathleen

2010-11-01

Each day thousands of blood donors across the country are given educational materials and sign a consent form, thus fulfilling two blood collection accreditation requirements. Very few donors will experience a documented adverse event, although a disproportionate number of these events occur in the youngest donor cohort. The literature reflects this disproportion and suggests mitigation strategies. Studies describe subjective, undocumented donor reactions and decreased donor return rates after a documented or subjective reaction. Additionally, studies have shown donor consent form variability among blood collection facilities and that donor comprehension of the educational materials and consent is limited. There are few standardized donor education materials or consent documents. Current accreditation standards for educational materials are limited to aspects of transfusion-transmitted diseases and for donor consent process and documentation are vague and nonspecific. Recent experiences with young donors and current research compel our community to engage in creating standardized, expanded donor educational materials and standardized donor consent processes and documents. © 2010 American Association of Blood Banks.

Player or referee? Aid effectiveness and the governance of health policy development: Lessons from Viet Nam.

PubMed

Dodd, Rebecca; Olivé, Jean-Marc

2011-01-01

Viet Nam is one of the brightest stars in the constellation of developing countries. Its remarkable achievements in reducing poverty and improving health and education outcomes are well known, and as a result it has enjoyed generous aid programmes. Viet Nam also has a reputation for taking a strong lead in disciplining its donors and pushing for more efficient and effective forms of aid delivery, both at home and internationally. This article discusses how efforts to improve the effectiveness of aid intersect with policy-making processes in the health sector. It presents a quantitative review of health aid flows in Viet Nam and a qualitative analysis of the aid environment using event analysis, participant observation and key informant interviews. The analysis reveals a complex and dynamic web of incentives influencing the implementation of the aid effectiveness agenda in the health sector. There are contradictory forces within the Ministry of Health, within government as a whole, within the donor community and between donors and government. Analytical frameworks drawn from the study of policy networks and governance can help explain these tensions. They suggest that governance of health aid in Viet Nam is characterised by multiple, overlapping 'policy networks' which cut across the traditional donor-government divide. The principles of aid effectiveness make sense for some of these communities, but for others they are irrational and may lead to a loss of influence and resources. However, sustained engagement combined with the building of strategic coalitions can overcome individual and institutional incentives. This article suggests that aid reform efforts should be understood not as a technocratic agenda but as a political process with all the associated tensions, perverse incentives and challenges. Partners thus need to recognise - and find new ways of making sense of - the complexity of forces affecting aid delivery.

Donor human milk is considered the next best nutrition following mother's own milk to prevent neonatal infection and necrotizing enterocolitis in preterm infants who are admitted at neonatal intensive care unit. However, donor milk biofunctionalities after preparative processes have rarely been documented. To evaluate biofunctionalities preserved in donor milk after preparative processes by cell-based assays. Ten pools of donor milk were produced from 40 independent specimens. After preparative processes, including bacterial elimination methods (holder pasteurization and cold-sterilization microfiltration) and storage conditions (-20°C freezing storage and lyophilization) with varied duration of storage (0, 3, and 6, months), donor milk biofunctionalities were examined by fetal intestinal cell growth and antimicrobial assays. At baseline, raw donor milk exhibited 193.1% ± 12.3% of fetal intestinal cell growth and 42.4% ± 11.8% of antimicrobial activities against Escherichia coli. After bacteria eliminating processes, growth promoting activity was better preserved in pasteurized donor milk than microfiltrated donor milk (169.5% ± 14.3% versus 146.0% ± 11.8%, respectively; p < 0.005), whereas antimicrobial activity showed no difference between groups (38.3% ± 14.1% versus 53.7% ± 17.3%, respectively; p = 0.499). The pasteurized donor milk was further examined for the effects of storage conditions at 3 and 6 months. Freezing storage, but not lyophilization, could preserve higher growth-promoting activity during 6 months of storage (163.0% ± 9.4% versus 72.8% ± 6.2%, respectively; p < 0.005). Nonetheless, antimicrobial activity was lost at 6 months, regardless of the storage methods. This study revealed that fetal intestinal cell growth and antimicrobial assays could be applied to measure donor milk biofunctionalities and support the utilization of donor milk within 3 months after preparative processes.

Assessment of the knowledge of living unrelated donors of the complications of kidney donation in Iran.

Living unrelated donors (LURDs) constitute the major source of renal allograft in Iran. LURD transplantation (Tx) is performed in a controlled program, supervised by university Tx teams, and assisted by the Dialysis and Transplant Patient's Association (DATPA). This study evaluated the knowledge of donors about possible short- and long-term complications of kidney donation and the need for regular follow-up. We interviewed 100 consecutive living donors/donation candidates (all called donors), 35 in the postoperative period in the renal Tx ward, and 65 after completion of preoperative assessment in the office of the DATPA, to assess their knowledge about complications of nephrectomy and their intention to participate in the postoperative follow-up. Seventy-nine donors were men and 21 women. Mean age was 27 +/- 4.4 years. Ninety-seven donors were unrelated to the recipient and three were related (LRD). The motivation for donation was altruistic in nine (three LRD and six LURD) and financial in 89. Eighty donors were not aware of the possible short- or long-term complications of nephrectomy. Six donors mentioned the possibility of potential intraoperative complications, and 16 mentioned the risk of renal failure. Only 44 donors knew that they should visit doctors regularly after donation, most of them (61%) from the postoperative group. We conclude that most donors do not have enough knowledge about possible in-hospital and long-term complications of kidney donation and may not participate in regular follow-up after operation. Considering the young age of our renal Tx donors, we suggest that they should receive more preoperative orientation (both verbal and written) about possible complications and the need for regular postoperative medical follow-up.

Embryo donation and counselling for the welfare of donors, recipients, their families and children.

How do counsellors facilitating known 'open' embryo donation (ED) experience their roles and responsibilities? Counsellors regard counselling for ED as entailing significant responsibility to ensure that the longer-term implications of the practice are understood and that positive relationships are established that will promote the well-being of donors, recipients, their families and the children involved. While counselling is frequently recommended in third-party assisted reproduction, there has been little research into the experiences of counsellors and their perceptions of their roles and responsibilities. Fertility counsellors were interviewed between March and October 2012 as to their experiences and perceptions of their roles and responsibilities. Fertility counsellors were recruited from across New Zealand and interviews were conducted with all nine counsellors involved in ED counselling. Interview data were analysed thematically to identify main themes. Counsellors regard ED as a complex practice with enduring implications arising from the genetic link between donors and offspring, which is seen to bestow immutable social ties. They see their role as the provision of implications counselling and the facilitation of ongoing positive relationships between donors and recipients in an 'open' context. Counsellors express concern about their responsibility for promoting the welfare of all parties--including that of the child--the limitations of counselling, and the conflation of assessment and counselling roles. Experiences of counselling for ED may change over time as longer-term outcomes become more apparent. Further consideration needs to be given as to how the welfare principle may best be operationalised in counselling practice, particularly in contexts of 'open' donation.

Funding Based on Needs? A Study on the Use of Needs Assessment Data by a Major Humanitarian Health Assistance Donor in its Decisions to Allocate Funds

PubMed Central

Olin, Emma; von Schreeb, Johan

2014-01-01

Background: International humanitarian assistance is essential for disaster-affected populations, particularly in resource scarce settings. To target such assistance, needs assessments are required. According to internationally endorsed principles, donor governments should provide funding for humanitarian assistance based on need. Aim: The aim of this study is to explore a major donor’s use of needs assessment data in decision-making for allocations of funds for health-related humanitarian assistance contributions. Setting: This is a case study of the Swedish International Development Cooperation Agency (Sida), a major and respected international donor of humanitarian assistance. Methods: To explore Sida’s use of needs assessment data in practice for needs-based allocations, we reviewed all decision documents and assessment memoranda for humanitarian assistance contributions for 2012 using content analysis; this was followed by interviews with key personnel at Sida. Results: Our document analysis found that needs assessment data was not systematically included in Sida’s assessment memoranda and decision documents. In the interviews, we observed various descriptions of the concept of needs assessments, the importance of contextual influences as well as previous collaborations with implementing humanitarian assistance organizations. Our findings indicate that policies guiding funding decisions on humanitarian assistance need to be matched with available needs assessment data and that terminologies and concepts have to be clearly defined. Conclusion: Based on the document analysis and the interviews, it is unclear how well Sida used needs assessment data for decisions to allocate funds. However, although our observations show that needs assessments are seldom used in decision making, Sida’s use of needs assessments has improved compared to a previous study. To improve project funds allocations based on needs assessment data, it will be critical to develop distinct frameworks for allocation distributions based on needs assessment and clear definitions, measurements and interpretations of needs. Key words: Needs assessment, humanitarian assistance, disasters, donor decision-making PMID:24894417

Variation in Pediatric Organ Donor Management Practices Among US Organ Procurement Organizations.

Reports of actual pediatric organ donor management practice among US organ procurement organizations are sparse, and the use of standardized management guidelines is unknown. A recent consensus statement from the Society of Critical Care Medicine, the American College of Chest Physicians, and the Association of Organ Procurement Organizations offers guidelines for the management of the pediatric organ donor. To describe the use of guidelines and routine practices in the management of the pediatric organ donor with respect to hemodynamics, lung and ventilator management, fluid and electrolytes, hormonal replacement therapy, the use of blood products, thermoregulation, and prophylactic antibiotics. Cross-sectional observational study using a survey and follow-up telephone interview with respondents from all 58 US organ procurement organizations. All 58 US Organ Procurement Organizations participated. A majority employed written guidelines for the management of pediatric donor hemodynamics, thermoregulation, fluids, and electrolytes. Management of blood products, the lung, and mechanical ventilation were less commonly committed to written guidelines, but common practices were described. All used various forms of hormonal replacement therapy and the majority administered empiric antibiotic therapy. Wide variation was observed in the management of the lung, mechanical ventilation, and glycemic control. Most OPOs used forms of standardized donor management for the pediatric organ donor although variation in the content of that management exists. Barriers to an evidence-based approach to the pediatric donor need to be determined and addressed.

Two mothers and a donor: exploration of children's family concepts in lesbian households.

Although children from lesbian families appear to make a distinction between a residential father and a donor, defining these two concepts seems to be a challenge. They need to appeal to more familiar concepts such as the hetero-normative concept of 'mother' to give a definition of the unfamiliar concepts they are confronted with. The study is based on qualitative in-depth interviews with 6 children (9-10 years old) from lesbian families, all of which have been conceived using anonymous sperm donation. Semi-structured interviews were conducted. Two findings stand out. First, in defining the concepts of biological and non-biological mother, both mothers were described as equal parents. No difference was attached by the children to the mothers' position as a parent. Second, the concepts 'non-biological mother' and 'donor' were defined by looking at the hetero-normative concepts of 'mummy' and 'daddy'. To define the non-biological mother, both a 'mummy' and a 'daddy' were used as a reference. To define the donor concept, often references were made to a daddy. This comparison with a 'daddy' turned out to be complex due to the conflict between the role as a progenitor and the lack of a social relationship. The lack of language surrounding this concept turned out to be difficult. This study illustrates the complexity and ambiguity of children's experiences and perceptions when dealing with issues related to genetic and social parenthood.

Specific demographic factors could predict deceased potential cornea donors: A retrospective study from Beijing Tongren Hospital Eye Bank.

Compared with evident cornea donors (ECDs), deceased potential cornea donors (DPCDs) have no obvious donor identifications to reference, which causes many eligible cornea tissues to be wasted. The demographic characteristics of DPCDs might be different from those of ECDs owing to the following different features: donation consent provided by relatives and willingness to donate before death. Thus, the aim of this study is to reveal the demographic characteristics of DPCDs by comparing DPCDs and ECDs.The demographic factors of 138 donors (both DPCDs and ECDs) were collected from the Beijing Tongren Hospital Eye Bank database and analyzed. To differentiate DPCDs from ECDs using the above-mentioned features, we interviewed the relatives of the donors by telephone. The relatives' attitudes toward cornea donation and their suggestions for our donation service were also acquired during the interview. Two logistic regressions were performed to reveal the demographic factors influencing the 2 features and indicate DPCDs.The donors had certain demographic characteristics (elderly, secondary, or tertiary education level, central district resident), and the most frequent cause of death for the donors was a malignant tumor (n = 56, 43.1%). All the relatives had positive attitudes toward cornea donations, and they hoped to increase publicity efforts to encourage more people to donate and establish more convenient and efficient access for cornea donation. In univariate regressions, age (P = .004, >50 years: odds ratio [OR] = 6.89, 95% confidence interval [CI]: 1.82-26.05), marital status (P = .043, divorced: OR = 9.00,95% CI: 1.33-60.80) significantly influenced relative consent, whereas age (P = .001, >50 years: OR = 15.00, 95% CI: 3.00-74.98), and family address (P = .001, central district: OR = 1) were significant factors influencing the willingness to donate before death. In multivariate regression, age (P = .021, >50 years: OR = 8.14, 95% CI: 1.37-48.41) was the only significant factor influencing relative consent. Similarly, age (P = .02, >50 years: OR = 7.55, 95% CI: 1.21-47.25) was the only factor influencing willingness to donate before death.In conclusion, specific demographic factors could indicate DPCDs and might reveal directions and methods for cornea donation coordination in the future.

Risk factors for Trypanosoma cruzi infection among blood donors in central Brazil.

1992-01-01

Characteristics and possible risk factors associated with Trypanosoma cruzi infection among blood donors were assessed within a routine screening programme in blood banks in an endemic area of Chagas disease. 6,172 voluntary blood donors were interviewed and tested for anti-T. cruzi antibodies by Haemagglutination and Complement Fixation tests in six blood banks in Goiânia-Central Brazil from October 1988 to April 1989. An overall prevalence of 2.3% for T. cruzi infection was obtained, being 3.3% for first-time blood donors and 1.9% for regular ones (p < 0.01). Considering this seropositivity among regular blood donors, selection of candidates relying only on the history of previous donation was found to be inadequate. The risk of infection increased inversely with the degrees of education and monthly income. There was a 9.2 risk of infection (95% CI 3.8-22.6) for those who had lived more than 21 years in an endemic area compared to subjects who had never lived in rural settings, after multivariate analysis. These informations may help to review the criteria of selection of donors in order to improve quality of blood products in endemic areas.

Afghanistan is a country with population of over 28 million. The long term conflicts have devastated country's qualified resources including human resources. ANBSTS was established by MoPH as the country national blood service. Currently in addition to central and regional blood centers of ANBSTS many other hospitals have their own transfusion services. Blood donation in Afghanistan mainly depends on replacement donors. Donor selection and donor interview are not very efficient. Most of the blood in Afghanistan is administered as fresh whole blood. Although blood transfusion services in Afghanistan require more efforts to be fully efficient, based on recent improvements in working procedures of ANBSTS a promising future for blood transfusion services in Afghanistan is predicted.

This study aimed to know the opinion of five different social segments (public prosecutors, judges, general population, recipients of the awaiting list for kidney transplants and the crew involved in the organ transplantation process of a hospital in Brasília--Hospital de Base) about the present organ transplant legislation, with an emphasis on the donation of kidney by unrelated living donors, and the new determination given by Law #10.211, in March 23rd, 2001, specifically in its article 9, that enlarges the criteria for donation of organs between unrelated living people. A questionnaire with six objective questions was used in order to know the opinion of five groups of people of the Federal District about the present organ transplant legislation in Brazil. For 80% of the people interviewed, when Brazilian legislation allows donation of organs between unrelated living people, it makes possible the existence of rewarded donation and 81% of them consider that the requirement for judicial authorization is not an effective instrument to prevent organ commercialism. The present research indicates that Brazilian legislation fails concerning the utilization of kidneys for transplantation from unrelated living donors, making possible the commerce of organs in the country. Considering that poor people are the most vulnerable ones in this context, the authors suggest changes in the legislation in force, aiming to protect them and, therefore, attain more justice.

Perceptions of donors and recipients regarding blood donation.

The aim of this study was to identify the perceptions of blood donors and recipients regarding the act of donating blood. This descriptive study with a survey design focuses on subjective and cultural aspects. Twenty donors and 20 recipients in the blood bank at the time of data collection participated in the study. Interviews were analyzed according to deductive thematic analysis. Two themes emerged - perceptions of donors and perceptions of recipients. Both groups saw the act of donating blood as something positive, though donors associated their reports with the experiences of people close to them who needed blood transfusions, while the recipients associated donations with the maintenance of their lives as, for them, a blood transfusion was a necessary medical treatment. Perceptions regarding blood donations are culturally constructed, as the participants associated knowledge acquired in the social world with moral issues and their life experiences. Hence, in addition to helping others, these individuals feel socially and morally rewarded. Copyright © 2016 Associação Brasileira de Hematologia, Hemoterapia e Terapia Celular.

Adult-to-adult living donor liver transplantation (LDLT) is a complex procedure that poses serious health risks to and provides no direct health benefit for the donor. Because of this uneven risk-benefit ratio, ensuring donor autonomy through informed consent is critical. To assess the current knowledge pertaining to informed consent for LDLT, we conducted a systematic review of the empirical literature on donors' decision-making process, comprehension about risks and outcomes, and information needs for LDLT. Of the 1423 identified articles, 24 met final review criteria, representing the perspective of approximately 2789 potential and actual donors. As donors' decisions to donate often occur before evaluation, they often make uninformed decisions. The review found that 88% to 95% of donors reported understanding information clinicians disclosed about risks and benefits. However, donors reported unmet information needs, knowledge gaps regarding risks, and unanticipated complications. Few donors reported feeling pressure to donate. Most studies were limited by cultural differences, small sample sizes, inconsistent measures, and poor methodological approaches. This systematic review suggests that informed consent for LDLT is sub-optimal as donors do not adequately appreciate disclosed information during the informed consent process, despite United Network for Organ Sharing/CMS regulations requiring formal psychological evaluation of donor candidates. Interventions are needed to improve donor-clinician communication during the LDLT informed consent process such as through the use of comprehension assessment tools and e-health educational tools that leverage adult learning theory to effectively convey LDLT outcome data.

To describe the current practice of pediatric organ donor management in the United States for donors declared dead based upon neurologic criteria. The study directs particular attention to how pediatric donors are defined, the use of donor management guidelines, the use of donor management goals, and the involvement of pediatric critical care or transplantation expertise. Cross-sectional observational study using a web-based survey and follow-up telephone interview with respondents from U.S. organ procurement organizations. The study also incorporated organ procurement organization-specific data on organ yield for the 4-year period (2010-2013) preceding the study. The 58 U.S. organ procurement organizations. Respondents chosen by each organ procurement organization. None. All 58 U.S. organ procurement organizations participated in the study. Fifty-two respondents (90%) indicated that their organ procurement organization distinguished pediatric from adult donors resulting in 28 unique pediatric definitions. Thirty-nine organ procurement organizations utilized some form of written pediatric management guidelines, and 27 (47%) maintained pediatric donor management goals; compliance was infrequently monitored for both guidelines (28%) and goals (33%). A pediatric intensivist was always or usually involved in pediatric donor management at 47 organ procurement organizations (81%); transplant/organ recovery surgeons were always or usually involved at 12 organ procurement organizations (21%). There was an increase in the number of organs transplanted per donor among donors 11-17 years old for organ procurement organizations that used donor management goals for the duration of the period studied (p < 0.01). There was also an increase in the ratio of observed/expected organs transplanted among donors of 0-10 years old for organ procurement organizations that always or usually consulted a transplant/organ recovery surgeon (p = 0.02) although this did not reach our threshold for statistical significance.. There is little consensus among organ procurement organizations regarding the definition of "pediatric" during organ donor management. Most organ procurement organizations employ written pediatric guidelines and use pediatric intensive care physicians for assistance in managing these donors. There is a positive association between the use of donor management goals and organ yield among pediatric donors in the 11- to 17-year age group.

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

Donor selection criteria for adult-to-adult living donor liver transplantation vary with the medical center of evaluation. Living donor evaluation uses considerable resources, and the nonmaturation of potential into actual donors may sometimes prove fatal for patients with end-stage liver disease. On the contrary, a thorough donor evaluation process is mandatory to ensure safe outcomes in otherwise healthy donors. We aimed to study the reasons for nonmaturation of potential right lobe liver donors at our transplant center. A retrospective data analysis of all potential living liver donors evaluated at our center from 1998 to 2010 was done. Overall, 324 donors were evaluated for 219 potential recipients, and 171 (52.7%) donors were disqualified. Common reasons for donor nonmaturation included the following: (1) donor reluctance, 21%; (2) greater than 10% macro-vesicular steatosis, 16%; (3) assisted donor withdrawal, 14%; (4) inadequate remnant liver volume, 13%; and (5) psychosocial issues, 7%, and thrombophilia, 7%. Ten donors (6%) were turned down because of anatomic variations (8 biliary and 2 arterial anomalies). Donors older than 50 years and those with body mass index of more than 25 were less likely to be accepted for donation. We conclude that donor reluctance, hepatic steatosis, and assisted donor withdrawal are major reasons for nonmaturation of potential into actual donors. Anatomic variations and underlying medical conditions were not a major cause of donor rejection. A system in practice to recognize these factors early in the course of donor evaluation to improve the efficiency of the selection process and ensure donor safety is proposed.

Hematopoietic stem cell transplantation (HSCT) is a medical procedure in the field of hematology and oncology, most often performed for patients with certain cancers of the blood or bone marrow. A lot of patients have no suitable HLA-matched donor within their family, so physicians must activate a "donor search process" by interacting with national and international donor registries who will search their databases for adult unrelated donors or cord blood units (CBU). Information and communication technologies play a key role in the donor search process in donor registries both nationally and internationaly. One of the major challenges for donor registry computer systems is the development of a reliable search algorithm. This work discusses the top-down design of such algorithms and current practice. Based on our experience with systems used by several stem cell donor registries, we highlight typical pitfalls in the implementation of an algorithm and underlying data structure.

1993-12-31

The role of hydrogen donor compounds in coal liquefaction has been extensively investigated since the mid 1960`s using model compounds and process derived hydrogen donor solvents. Our recent research and that of other investigators have shown that two model compounds in particular have great efficacy in solvating low rank coals. 1,2,3,10b tetrahydrofluoranthene (H{sub 4}Fl) and 1,2,3,6,7,8 hexahydropyrene (H{sub 6}Py) have been used to dissolve Wyodak coal to > 95% soluble material as measured by tetrahydrofuran (THF). Although these hydrogen donors are very effective, they may not be found in any significant concentrations in actual liquefaction process recycle solvents. Therefore, studiesmore » with process derived recycle materials are necessary to understand donor solvent chemistry. The objective of this paper is to present results of solvent hydrogenation experiments using heavy distillate solvents produced during testing at the Wilsonville Advanced Coal Liquefaction Test Facility. We evaluated the impact of hydrogenation conditions upon hydrogen donor formation in process derived distillates and compared these process derived solvents with the highly effective H{sub 4}Fl and H{sub 6}Py donors in coal liquefaction tests. This paper presents data on reaction conditions used for distillate hydrotreating and subsequent coal liquefaction, with an aim toward understanding the relationship between reaction conditions and donor solvent quality in recycle distillates.« less

What are the perspectives of adolescents conceived using surrogacy, egg or sperm donation regarding their conception and the third party involved? The majority of adolescents described feeling indifferent about their conception, and yet simultaneously reported an interest in the third party involved, or were in contact with them. There is an assumption that children conceived through reproductive donation will feel negatively about their origins in adolescence. However, little is known about the views of adolescents who have been conceived through different types of reproductive donation. Forty-four adolescents, all of whom had been told about their conception in childhood, participated in a semi-structured interview as part of the sixth phase of a longitudinal, multi-method, multi-informant study of assisted reproduction families in the UK. All adolescents were aged 14 years, had been conceived using surrogacy (n = 22), egg donation (n = 13) or sperm donation (n = 9) to heterosexual couples, and varied in terms of their information about, and contact with, the third party involved in their conception. Semi-structured interviews were conducted in participants' homes. Interviews were analysed qualitatively to determine adolescents' perceptions of their conception, and their thoughts and feelings about the surrogate or donor involved. Adolescents were found to feel positive (n = 7), indifferent (n = 32) or ambivalent (n = 5) about their conception. Amongst adolescents not in contact with the surrogate or donor, most were interested (n = 16) in the surrogate or donor, and others were ambivalent (n = 4), or not interested (n = 6) in them. Adolescents in contact with the surrogate or donor expressed positive (n = 14), ambivalent (n = 1) or negative (n = 1) feelings about them. Of 56 adolescents invited to take part in the study, 47 consented to take part, giving a response rate of 84%. It was not possible to obtain information from adolescents who do not know about their conception. The findings contradict the assumption that children conceived through reproductive donation will feel negatively about their origins in adolescence and suggest that it may be helpful to draw a distinction between adolescents' feelings about their conception in general, and their feelings about the surrogate or donor in particular. This study was funded by the Wellcome Trust [097857/Z/11/Z]. The authors have no conflicts of interest to declare.

Context The increasing shortage of deceased donor kidneys suitable for African Americans highlights the critical need to increase living donations among African Americans. Little research has addressed African American transplant recipients’ perspectives on challenges and barriers related to the living donation process. Objective To understand the perspectives of African American recipients of deceased and living donor kidney transplants on challenges, barriers, and educational needs related to pursuing such transplants. Participants and Design A mixed-method design involved 27 African American kidney recipients (13 male) in 4 focus groups (2 per recipient type: 16 African American deceased donor and 11 living donor recipients) and questionnaires. Focus group transcripts were evaluated with NVivo 10.0 (QSR, International) by using inductive and deductive qualitative methods along with crystallization to develop themes of underlying barriers to the living donor kidney transplant process and were compared with the questionnaires. Results Four main themes were identified from groups: concerns, knowledge and learning, expectations of support, and communication. Many concerns for the donor were identified (eg, process too difficult, financial burden, effect on relationships). A general lack of knowledge about the donor process and lack of behavioral skills on how to approach others was noted. The latter was especially evident among deceased donor recipients. Findings from the questionnaires on myths and perceptions supported the lack of knowledge in a variety of domains, including donors’ surgical outcomes risks, costs of surgery, and impact on future health. Participants thought that an educational program led by an African American recipient of a living donor kidney transplant, including practice in approaching others, would increase the likelihood of transplant-eligible patients pursuing living donor kidney transplant.

The applicability of modified spent caustic (MSC) as an electron donor for denitrification was evaluated in a lab-scale reactor for the Bardenpho process under various electron donor conditions: (A) no electron donor, (B) methanol, (C) thiosulfate and (D) MSC conditions. TN removal efficiency varied in each condition, 23.1%, 87.8%, 83.7% and 71.7%, respectively. The distribution ratio of nitrifying bacteria and DGGE profile including sulfur-reducing or oxidizing bacteria also varied depending on the conditions. These results indicated that the MSC would be used as an efficient electron donor for denitrification by autotrophic denitrifier in wastewater treatment process. Copyright 2009 Elsevier Ltd.

The provision of donor human milk avoids the risks associated with early infant formula feeding only when maternal milk is unavailable. Donor human milk-banking services (DHMBS) should provide an effective clinical service that causes no harm to donors or recipients. This article aims to begin the process of defining the minimum acceptable standard required for safe donor human milk banking in the neonatal unit. An assessment process is established to consider the potential risks and benefits of milk banking to both recipients and donors. These risks and benefits define the clinical responsibility of DHMBS and their social responsibility. Copyright © 2016 Elsevier Inc. All rights reserved.

The Saint Louis hospital tissue bank provides skin allografts to pediatric and adult burn units in the Paris area. The aim of this study was to analyze our activity during the last 11 years focusing on the reasons for skin discard. Skin is procured solely from the back of the body, which is divided into 10 zones that are harvested and processed separately. This retrospective study included all skin donors harvested between June 2002 and June 2013, representing a total of 336 donors and 2770 zones. The donors were multiorgan heart-beating donors in 91 % of cases (n = 307). The main reason for discarding harvested skin was microbial contamination, detected in 99 donors (29 %). Most contaminants were of low pathogenicity. Other reasons for discard included positive serologic tests for 2 donors [17 zones (0.61 %)], unsuitable physical skin characteristics for 3 zones (0.11 %), the donor's medical history for 53 zones (1.91 %), and technical issues with processing or distribution for 61 zones (2.2 %). In our experience, microbial contamination continues to be the main reason for discarding potential skin allografts. However, discards are limited by separate harvesting and processing of multiple zones in each donor.

Use of donor milk in the neonatal intensive care unit.

2017-02-01

Own mother's milk is the first choice in feeding preterm infants and provides multiple short- and long-term benefits. When it is unavailable, donor human milk is recommended as the first alternative. Donor milk undergoes processing (i.e. pasteurization) to reduce bacteriological and viral contaminants but influences its bioactive properties with potentially fewer benefits than raw milk. However, there is no clinical evidence of health benefit of raw compared to pasteurized human milk, and donor milk maintains documented advantages compared to formula. Nutrient content of donor and own mother's milk fails to meet the requirements of preterm infants. Adequate fortification is necessary to provide optimal growth. There are significant challenges in providing donor milk for premature infants; therefore, specific clinical guidelines for human milk banks and donor milk use in the neonatal intensive care unit should be applied and research should focus on innovative solutions to process human milk while preserving its immunological and nutritional components. In addition, milk banks are not the only instrument to collect, process and store donor milk but represent an excellent tool for breastfeeding promotion. Copyright © 2016 Elsevier Ltd.

Research suggests that African migrants are often positively predisposed towards blood donation, but are under-represented in participation. A culturally-tailored intervention targeting the African migrant community in Australia was developed and implemented, to enhance knowledge about blood donation, improve attitudes towards donating, increase intentions to donate blood, and increase the number of new African donors in Australia. Four weeks after a targeted campaign, a survey evaluation process commenced, administered face-to-face by bilingual interviewers from the African community in Melbourne and Adelaide, Australia (community survey). The questionnaires covered demographics, campaign awareness, blood donation knowledge and intentions, medical mistrust and perceived discrimination, and were analysed to evaluate changes in knowledge and intention. Sixty-two percent of survey participants (n = 454) reported being aware of the campaign. With increasing campaign awareness, there was a 0.28 increase in knowledge score (p = .005); previous blood donation was also associated with an increased blood donation knowledge score. Blood donation intention scores were not associated with campaign awareness (p = 0.272), but were associated with previous blood donation behaviour and a positive blood donation attitude score. More positive scores on the blood donation attitude measure were associated with increasing blood donation intentions, self-efficacy and campaign awareness (score increases of 0.27, 0.30 and 0.04, respectively, all p<0.05). Data were collected on the ethnicity of new blood donors in six blood collection centres before and after the intervention, and independent of the intervention evaluation survey. These data were also used to assess behavioural changes and the proportions of donors from different countries before and after the survey. There was no difference in the number of new African migrant donors, before and after the intervention. The culturally-relevant marketing campaign was associated with improved blood donation knowledge and attitudes, but there was no short-term change in blood donation intentions or the number of African donors.

Failure of bacterial screening to detect Staphylococcus aureus: the English experience of donor follow-up.

Between February 2011 and December 2016, over 1·6 million platelet units, 36% pooled platelets, underwent bacterial screening prior to issue. Contamination rates for apheresis and pooled platelets were 0·02% and 0·07%, respectively. Staphylococcus aureus accounted for 21 contaminations, including four pooled platelets, one confirmed transfusion-transmitted infection (TTI) and three 'near-miss' incidents detected on visual inspection which were negative on screening. We describe follow-up investigations of 16 donors for skin carriage of S. aureus and molecular characterisation of donor and pack isolates. Units were screened by the BacT/ALERT 3D detection system. Contributing donors were interviewed and consent requested for skin and nasal swabbing. S. aureus isolates were referred for spa gene type and DNA macrorestriction profile to determine identity between carriage strains and packs. Donors of 10 apheresis and two pooled packs screen positive for S. aureus were confirmed as the source of contamination; seven had a history of skin conditions, predominantly eczema; 11 were nasal carriers. The 'near-miss' incidents were associated with apheresis donors, two donors harboured strains indistinguishable from the pack strain. The TTI was due to a screen-negative pooled unit, and a nasal isolate of one donor was indistinguishable from that in the unit. Staphylococcus aureus contamination is rare but potentially harmful in platelet units. Donor isolates showed almost universal correspondence in molecular type with pack isolates, thus confirming the source of contamination. The importance of visual inspection of packs prior to transfusion is underlined by the 'near-miss' incidents. © 2018 International Society of Blood Transfusion.

The Susan G. Komen for the Cure Tissue Bank at the IU Simon Cancer Center (KTB) was established in 2007 with funding from Susan G. Komen for the Cure to provide scientists with a resource for normal breast tissue. To date, nearly 3,500 women have donated their healthy breast tissue to the bank, but little is known about their perspectives. This study was designed to examine their motivations, concerns, and experiences. We conducted brief interviews with donors (n = 221) to investigate their donation-related motivations, concerns, and experiences. Donor responses were coded and quantitatively analyzed (descriptive statistics and χ(2)). The most frequent motivation to donate (48% of donors) was personal connection to a breast cancer patient/survivor. A majority of donors (60%) were unconcerned about donation before the event; reported concerns included pain, fear, and dislike of surgical procedures. The most frequent positive experiences were minimal pain and positive behavior by KTB staff and volunteers. A majority of donors (61%) reported no negative experience, but reported negative experiences included the biopsy machine and anesthetic. Younger donors (ages 18-24) reported more concerns and negative experiences than older donors (25+). Donors of healthy breast tissue are motivated by survivor connections and the ability to help by donating. Their concerns and experiences are relatively positive and consistent with undergoing a minor surgical procedure. Younger donors have more concerns and negative experiences. Findings from this study can inform recruitment campaigns and donation procedures for banking of healthy tissue. ©2014 American Association for Cancer Research.

If I Could in a Small Way Help”: Motivations for and Beliefs about Sample Donation for Genetic Research

Human genome research depends upon participants who donate genetic samples, but few studies have explored in depth the motivations of genetic research donors. This mixed methods study examines telephone interviews with 752 sample donors in a U.S. genetic epidemiology study investigating colorectal cancer. Quantitative and qualitative results indicate that most participants wanted to help society, and that many also wanted information about their own health, even though such information was not promised. Qualitative analysis reveals that donors believed their samples contributed to a scientific “common good”; imagined samples as information rather than tissues; and often blurred distinctions between research and diagnostic testing of samples. Differences between African American and White perspectives were distinct from educational and other possible explanatory factors. PMID:21680977

In August 2002, fever and mental-status changes developed in recipients of organs from a common donor. Transmission of West Nile virus through organ transplantation was suspected. We reviewed medical records, conducted interviews, and collected blood and tissue samples for testing with a variety of assays. Persons who donated blood to the organ donor and associated blood components were identified and tested for West Nile virus. We identified West Nile virus infection in the organ donor and in all four organ recipients. Encephalitis developed in three of the organ recipients, and febrile illness developed in one. Three recipients became seropositive for West Nile virus IgM antibody; the fourth recipient had brain tissue that was positive for West Nile virus by isolation and nucleic acid and antigen assays. Serum specimens obtained from the organ donor before and immediately after blood transfusions showed no evidence of West Nile virus; however, serum and plasma samples obtained at the time of organ recovery were positive on viral nucleic acid testing and viral culture. The organ donor had received blood transfusions from 63 donors. A review of blood donors and follow-up testing identified one donor who had viremia at the time of donation and who became seropositive for West Nile virus IgM antibodies during the next two months. Our investigation of this cluster documents the transmission of West Nile virus by organ transplantation. Organ recipients receiving immunosuppressive drugs may be at high risk for severe disease after West Nile virus infection. Blood transfusion was the probable source of the West Nile virus viremia in the organ donor. Copyright 2003 Massachusetts Medical Society

Health history questions are introduced into the predonation interview to identify blood donors believed to pose a higher risk of infectious diseases to recipients. This study assesses the current impact of some of those questions. Donor deferral and donation data were extracted from a research database of the American Red Cross. The prevalence of hepatitis B surface antigen or antibodies to human immunodeficiency virus, hepatitis C virus, or human T-lymphotropic virus was obtained for different groups of donors who were temporarily deferred in 2000 through 2001 and later returned to donate blood in 2000 through 2003. The results were compared with either first-time or repeat donors in 2000 through 2003, while controlling for differences in sex, age, and year of donation. Of donors temporarily deferred in 2000 through 2001 who had had no donation or deferral during the previous 2 years, only 22.08 percent subsequently returned to donate blood in 2000 through 2003. Donations from returning donors who had been deferred for potential infectious disease risk did not show a higher prevalence for any of the viral markers when those with no donation or deferral during the previous two years were compared with first-time donations, and those with prior donation were compared with repeat donations. Blood donors temporarily deferred in 2000 through 2001 for potential risk of viral infection who later returned to donate blood did not appear to pose a higher risk compared to first-time or repeat donors. The effectiveness of some of the currently used deferral questions in reducing viral risks warrants further study.

Context Although graft and patient survival rates for living kidney donation are improved, some healthcare providers question whether volunteer donors and their informal caregivers are fully informed of the donation process and the risks involved. Donors and their family caregivers have reported that they receive limited information about the predonation and donor recovery process. Offering web-based information and social support is one way to address this gap. Strategy Living kidney donor candidates and their family caregivers participating in the Living Donor Information Network for Caregiving (LINC) have access to a variety of online informational resources and a social support discussion forum throughout their living kidney donation experience. Strategies in the development and implementation of an online information and social-support resource are presented. Conclusions Use of the LINC website for information and support may assist health care providers in identifying potential barriers in the current donation process and provide direction for enhancing knowledge and confidence among donors and family caregivers.

Darr, A; Randhawa, G

1999-01-01

Currently the demand for transplant organs, particularly kidneys, far outstrips the supply in the UK. This problem is particularly severe for the Asian population, which has been shown to have a disproportionately large representation on kidney-transplant waiting lists in some regions of the UK. The situation is clear: there is an urgent need to address the number of Asians requiring a kidney transplant, otherwise the human and economic costs will be very high. An exploratory qualitative study was therefore undertaken with the aim of assessing current awareness of organ donation and transplantation and to explore attitudes towards these issues in a cross section of the Asian population in Luton. It was found that nearly half of the respondents in this survey did not know what a donor card was used for, and approximately half of these had never seen one; only 6 of the 64 people interviewed had heard of the National Donor Register. Of the three people who carried a donor card, two had an immediate family member who had received a transplant. This suggests that media campaigns aimed at attracting donors from the Asian population have had limited success thus far. It appears that the vast majority of the Asian population is at the initial stage of the process of making a decision about donating their organs, that of simply knowing that transplantation takes place. Very little debate of pertinent issues seems to have taken place, which is essential for reaching a decision on whether or not to donate an organ. The study should be seen as exploratory but is nonetheless an important initial step towards the establishment of a greater knowledge and understanding of the issues affecting the low donation rate in the Asian population.

The aim of this study was to examine donor complications, satisfaction with the liver donation process, and factors associated with re-donation. To address these issues, we conducted a cross-sectional study to assess donor complications and used questionnaires (including the Likert scale for donation satisfaction and simple yes/no responses for willingness to re-donate) in 110 adults who underwent living donor liver transplantation (LDLT) at Tri-Service General Hospital. The following clinical characteristics were determined: donation volume; first-degree relative; education; duration of hospital stay; occupation (donor-associated); MELD score; Child classification; complications; outcome (recipient-associated); and graft/recipient weight ratio (donor-recipient-associated). Descriptive statistics and mean values were compared using t-tests and p values <0.05 were considered significant. Twelve donors among 110 participants experienced complications above Clavien grade II. No surgical mortalities were observed. There were no differences in age, gender, left/right liver graft, donation volume, length of hospital stay, or satisfaction in donor complications. Ninety-four donors had satisfaction (score=4 and 5) about the donation process and no dissatisfaction was reported (score=1). Based on multivariate analysis, the intention to re-donate among liver donors was related to first-degree relatives, donor satisfaction, and recipient complications (P<0.05). Factors associated with a willingness to re-donate included first-degree relatives of the recipient, donor satisfaction with the donation process, and recipient complications. This study not only showed the safety of liver donation, but also had a positive effect on the intention to re-donate to enhance motivation for liver donation and increase the recruitment of living liver donors.

Breast milk donation and social support: reports of women donors.

The study aimed to characterize the behavior of human milk donation and to describe the informal social and formal institutional support, according to reports from women donors. It is an exploratory, cross-sectional, descriptive study using domicile interviews based on structured and semi-structured scripts. The participants were 36 women enrolled in two human milk banks of the public health system of the Federal District. Statistical analysis of quantitative data and categorical content analysis of qualitative data were performed. Categories of reasons that most influenced the frequency of expressing were: food, time availability, negative emotions and fluid intake. The manual expressing technique was reported as predominant. The use of breast shells was cited by almost a third of the donors. Most frequent suggestions for improving institutional support were more attention and support from the milk banks for the donor. The study may serve as a stimulus for the implementation of technical and political strategies to encourage this practice.

Challenges to achieving sustainable community health development within a donor aid business model.

PubMed

Ashwell, Helen; Barclay, Lesley

2010-06-01

This paper explores the paradox of donor aid being delivered through a business model through a case study in Papua New Guinea. A retrospective review of project implementation and an outcome evaluation provided an opportunity to examine the long-term results and sustainability of a large project. Analysis was informed by data collected from 175 interviews (national, provincial, district and village), 93 community discussions and observations across 10 provinces. Problems with the business model of delivering aid were evident from implementation data and in an evaluation conducted two years after project completion (2006). Compounding the business model effect were challenges of over-ambitious project goals with limited flexibility to adapt to changing circumstances, a donor payment system requiring short-term productivity and excessive reporting requirements. An overly ambitious project design, donor dominance within the business model and limited local counterpart capacity created problems in the community initiatives component of the project. Contractual pressures can negatively influence long-term outcomes that require development of local leadership and capacity. Future planning for donor project designs needs to be flexible, smaller in scope and have a longer timeframe of seven to 10 years. Donor-funded projects need to be sufficiently flexible to apply proven principles of community development, build local ownership and allow adequate time to build counterpart knowledge and skills.

Australian perioperative nurses' experiences of assisting in multi-organ procurement surgery: a grounded theory study.

2015-03-01

Multi-organ procurement surgical procedures through the generosity of deceased organ donors, have made an enormous impact on extending the lives of recipients. There is a dearth of in-depth knowledge relating to the experiences of perioperative nurses working closely with organ donors undergoing multi-organ procurement surgical procedures. The aim of this study was to address this gap by describing the perioperative nurses experiences of participating in multi-organ procurement surgical procedures and interpreting these findings as a substantive theory. This qualitative study used grounded theory methodology to generate a substantive theory of the experiences of perioperative nurses participating in multi-organ procurement surgery. Recruitment of participants took place after the study was advertised via a professional newsletter and journal. The study was conducted with participants from metropolitan, rural and regional areas of two Australian states; New South Wales and Western Australia. Thirty five perioperative nurse participants with three to 39 years of professional nursing experience informed the study. Semi structured in-depth interviews were undertaken from July 2009 to April 2010 with a mean interview time of 60 min. Interview data was transcribed verbatim and analysed using the constant comparative method. The study results draw attention to the complexities that exist for perioperative nurses when participating in multi-organ procurement surgical procedures reporting a basic social psychological problem articulated as hiding behind a mask and how they resolved this problem by the basic social psychological process of finding meaning. This study provides a greater understanding of how these surgical procedures impact on perioperative nurses by providing a substantive theory of this experience. The findings have the potential to guide further research into this challenging area of nursing practice with implications for clinical initiatives, management practices and education.

Computer applications in the search for unrelated stem cell donors.

PubMed

Müller, Carlheinz R

2002-08-01

The majority of patients which are eligible for a blood stem cell transplantation from an allogeneic donor do not have a suitable related donor so that an efficient unrelated donor search is a prerequisite for this treatment. Currently, there are over 7 million volunteer donors in the files of 50 registries in the world and in most countries the majority of transplants are performed from a foreign donor. Evidently, computer and communication technology must play a crucial role in the complex donor search process on the national and international level. This article describes the structural elements of the donor search process and discusses major systematic and technical issues to be addressed in the development and evolution of the supporting telematic systems. The theoretical considerations are complemented by a concise overview over the current state of the art which is given by describing the scope, relevance, interconnection and technical background of three major national and international computer appliances: The German Marrow Donor Information System (GERMIS) and the European Marrow Donor Information System (EMDIS) are interoperable business-to-business e-commerce systems and Bone Marrow Donors World Wide (BMDW) is the basic international donor information desk on the web.

Donor motivation in Xi'an, China: comparison with Canadian donors.

In China, paid donation is prohibited by law. There is little literature assessing donor motivation in China, and comparison with western countries such as Canada is important in understanding the application of Western literature. We compared motivational factors in donors from the city of Xi'an, China, with Canadian donors matched for age, sex and donation status. A total of 218 donors in Xi'an completed an interview about motivation as did 218 Canadian donors matched for age, sex and donation status. Frequencies and percentages of responses to questions were tabulated and compared using the Chi-squared test. Donors in Xi'an and Canada felt a personal responsibility to donate blood (81·2% vs. 78·0%, P = 0·2057), but Xi'an donors were more likely to consider blood donation a social responsibility (81·7% vs. 45·2%, P < 0·0001). Xi'an donors more often believed that society views donation as a normal activity (98·6% vs. 48·4%, P < 0·0001) and that the social atmosphere promotes donation (90·3% vs. 53·5%, P < 0·0001) and saw greater health benefit (52·3% vs. 12·5%, P < 0·0001). Most Xi'an donors believed in balance between their life force (Qi) and blood (86·7% vs. 49·8%, P < 0·0001) but did not believe blood lost from donating would affect this (0·5% vs. 3·8%, P = 0·01). While traditional Chinese beliefs may not be seen as a barrier among people in Xi'an who donate blood, blood donation is seen differently than by Canadian donors. There is a need for more research specific to China to tailor recruitment strategies. © 2012 The Author(s). Vox Sanguinis © 2012 International Society of Blood Transfusion.

Another person's heart: magical and rational thinking in the psychological adaptation to heart transplantation.

PubMed

Inspector, Yoram; Kutz, Ilan; David, Daniel

2004-01-01

The goal of this study was to examine heart transplant recipients' psychological adaptation to another person's heart, with particular emphasis on recipients' attitudes toward graft and donor. Thirty-five male heart recipients were examined by: the Symptom Distress Checklist (revised) (SCL-90-R); the Depression Adjective Checklist (DACL); a Post-Traumatic Stress Disorder Questionnaire (PTSD-Q); a Heart Image Questionnaire (HIQ); and a Semi-Structured Interview (SSI), aimed at eliciting attitudes and fantasies regarding the transplanted heart. All instruments indicated high levels of stress even several years after the transplant, but, simultaneously, 73% of recipients felt that acquiring a new heart had had a dramatic influence on their lives with a new appreciation of the preciousness of life and a shift of priorities, toward altruism and spirituality. Sixty percent returned to work after the transplant but some had to adapt to a changed attitude from those around them who regarded them as anything from mystical creatures to vulnerable or still-sick individuals. While all recipients possessed a scientific knowledge of the anatomy and physiological significance of the heart (as revealed in the HIQ), many endorsed fantasies and displayed magical thinking: 46% of the recipients had fantasies about the donor's physical vigor and prowess, 40% expressed some guilt regarding the death of the donor, 34% entertained the possibility of acquiring qualities of the donor via the new heart. When asked to choose a most and least preferred imagined donor, 49% constructed their choices according to prejudices, desires, or fears related to ethnic, racial or sexual traits attributed to the donor. This study confirms the intuitive idea that heart transplant involves a stressful course of events that produces an amplified sense of the precariousness of existence. Simultaneously, it gives rise to rejoicing at having been granted a new lease on life and a clear sense of new priorities, especially with regard to relationships. Less expectedly, this study shows that, despite sophisticated knowledge of anatomy and physiology, almost half the heart recipients had an overt or covert notion of potentially acquiring some of the donor's personality characteristics along with the heart. The concomitance of the magical and the logical is not uncommon in many areas of human existence, and is probably enhanced by the symbolic nature of the heart, and maybe, also, by the persistent stress that requires an ongoing, emotionally intense, adaptation process.

Lived Experiences of Iranian Nurses Caring for Brain Death Organ Donor Patients: Caring as “Halo of Ambiguity and Doubt”

Background: Brain death is a concept in which its criteria have been expressed as documentations in Harvard Committee of Brain Death. The various perceptions of caregiver nurses for brain death patients may have effect on the chance of converting potential donors into actual organ donors. Objective: The present study has been conducted in order to perceive the experiences of nurses in care-giving to the brain death of organ donor patients. Methods: This qualitative study was carried out by means of Heidegger’s hermeneutic phenomenology. Eight nurses who have been working in ICU were interviewed. The semi-structured interviews were recorded by a tape-recorder and the given texts were transcribed and the analyses were done by Van-Mannen methodology and (thematic) analysis. Results: One of the foremost themes extracted from this study included ‘Halo of ambiguity and doubt’ that comprised of two sub-themes of ‘having unreasonable hope’ and ‘Conservative acceptance of brain death’. The unreasonable hope included lack of trust (uncertainty) in diagnosis and verification of brain death, passing through denial wall, and avoidance from explicit and direct disclosure of brain death in patients’ family. In this investigation, the nurses were involved in a type of ambiguity and doubt in care-giving to the potentially brain death of organ donor patients, which were also evident in their interaction with patients’ family and for this reason, they did not definitely announce the brain death and so far they hoped for treatment of the given patient. Such confusion and hesitance both caused annoyance of nurses and strengthening the denial of patients’ family to be exposed to death. Conclusion: The results of this study reveal the fundamental perceived care-giving of brain death in organ donor patients and led to developing some strategies to improve care-giving and achievement in donation of the given organ and necessity for presentation of educational and supportive services for nurses might become more evident than ever.

Fund-raising is a new practice in medical education research. This qualitative study explores a cross-sectional analysis of philanthropy in medical education in Canada and Europe and identifies some common characteristics in the fund-raising system, key roles and characteristics of research sites that have had success. Medical education research sites that had received donations greater than Can$100 000 were identified by searching publicly available sources. Interviews were conducted with 25 individuals from these and other sites, in four categories: medical education leaders (n = 9); philanthropy-supported chairholders and researchers (n = 5); donors of over Can$100 000 (n = 7), and advancement professionals (n = 4). Interview transcripts were inductively coded to identify themes. Five factors associated with success in accessing philanthropic sources were identified in the sample: support of the organisation's senior leadership; a charismatic champion who motivates donors; access to an advancement office or foundation; impetus to find funds beyond traditional operating budgets, and understanding of the conceptual and practical dimensions of fund-raising. Three types of donor (medical education insider, donor collective and general philanthropist), four faculty roles (trailblazers, rock stars, 'Who? Me?' people and future fund-raisers) and six stages in the fund-raising cycle were also identified. Philanthropy is a source of funding with the potential to significantly advance education research. Yet competence in fund-raising is not widely developed among medical education research leaders. Successful accessing of philanthropic sources of funding requires the ability to articulate the impact of philanthropy in medical education research in a way that will interest donors. This appears to be challenging for medical education leaders, who tend to frame their work in academic terms and have trouble competing against other fund-raising domains. Medical education research institutes and centres will benefit from developing greater understanding of the conception and practices of fund-raising. © 2017 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

2017-01-01

Background: Long-term financial support is essential for the survival of a charitable organization. Health charities need to identify the effective factors influencing donor retention. Methods: In the present study, the items of a questionnaire were derived from both literature review and semi-structured interviews related to donor retention. Using a purposive sampling, 300 academic and executive practitioners were selected. After the follow- up, a total of 243 usable questionnaires were prepared for factor analysis. The questionnaire was validated based on the face and content validity and reliability through Cronbach’s α-coefficient. Results: The results of exploratory factor analysis extracted 2 factors for retention: donor factor (variance = 33.841%; Cronbach’s α-coefficient = 90.2) and charity factor (variance = 29.038%; Cronbach’s α-coefficient = 82.8), respectively. Subsequently, confirmatory factor analysis was applied to support the overall reasonable fit. Conclusions: In this study, it was found that repeated monetary donations are supplied to the charitable organizations when both aspects of donor factor (retention factor and charity factor) for retention are taken into consideration. This model could provide a perspective for making sustainable donations and charitable giving PMID:28955663

Evaluation of blood donor deferral causes in the Trinidad and Tobago National Blood Transfusion Service.

The majority of blood donations in Trinidad and Tobago are made as replacement by family members or friends. National Blood Transfusion Policy was drafted in 2007 to promote voluntary, repeated donation. The objective of this study is to assess the current rate and reasons for donor deferral, and the aim is to guide the proposed donor education and recruitment programme. A retrospective study of pre-donation deferral of prospective blood donors at the National Blood Transfusion Centre, Port of Spain, Trinidad and Tobago, was conducted. Records of all pre-donation deferrals over a 12-month period were studied. As many as 11,346 pre-donation screening interviews were conducted. There were 4043 (35.6%) deferrals. The most common reasons for donor deferral were exposure to high-risk sexual activity (27.6%), low haemoglobin 22.2% and hypertension 17.5%. Other reasons such as medication, chronic medical illness, tattoos, travel history, recent pregnancy, surgery or presentation outside the accepted age limit caused 33.8% of all deferrals and the majority (34.7%) of male deferrals. Low haemoglobin (44.5%) was the most common reason among females. The rate of deferral of voluntary donors was not significantly different from that for replacement donors (31.7 vs. 35.4%, P = 0.25). This study exposed a lack of public awareness as the principal reason for an unacceptably high rate of donor deferral. Donor education about selection criteria needs to be urgently addressed as an objective of the National Policy. Monitoring and evaluation of deferral rates and reasons could be used as one indicator of the effectiveness of the Policy.

Prosthetic mask restoration of the donor face is essential in current facial transplant protocols. The aim was to develop a new three-dimensional (3D) printing (additive manufacturing; AM) process for the production of a donor face mask that fulfilled the requirements for facial restoration after facial harvest. A digital image of a single test person's face was obtained in a standardized setting and subjected to three different image processing techniques. These data were used for the 3D modeling and printing of a donor face mask. The process was also tested in a cadaver setting and ultimately used clinically in a donor patient after facial allograft harvest. and Conclusions: All the three developed and tested techniques enabled the 3D printing of a custom-made face mask in a timely manner that is almost an exact replica of the donor patient's face. This technique was successfully used in a facial allotransplantation donor patient. Copyright © 2016 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd.

Deceased donor rates in Asia are among the lowest in the world. This has necessitated a reliance on living kidney donation, which has given rise to concerns about donor motivation and assessment in this region. We aimed to describe transplant professional perspectives on living kidney donor evaluation in Asia. Face-to-face, semistructured interviews were conducted with 53 transplant professionals (nephrologists [n = 21], surgeons/urologists [n = 17], coordinators [n = 7], social workers [n = 5], ethicists [n = 2], psychologist [n = 1]) from 20 centers in 10 countries. Transcripts were analyzed thematically to identify themes. The theme of traversing vulnerability overarched 4 themes. Vigilance against exploitation of the vulnerable meant mitigating the threat of commercial transplantation, combating disparities, and verifying volunteerism. Maintaining clarity of professional roles encompassed the perceived necessity of legal safeguards to determine legitimacy of relationships, ensuring informed consent, demarcating responsibilities, minimizing conflict of interest, meeting community expectations, and resolving ambivalence regarding donor risk. Societal plight driving caution about living kidney donor assessment was emphasized in the context of poverty and desperation, higher risk of disease, and lack of social security. Navigating sociocultural barriers acknowledged the centrality of the family, economic priorities, distrust in modern medicine, generational traditions, and emotional opacity limiting their ability to gauge donor motivation. Moral, professional, sociocultural and societal vulnerabilities contribute to the barriers and ethical quandaries in living kidney donation in Asia. Strategies are needed to address culturally based anxieties and disparities in living donation. Transplant professionals depend on strong legislation and policies to prevent exploitation of living donors.

The increasing number of patients requiring transplantation has brought about a shortage of donor kidneys. Incentives can potentially improve organ donation. There is a need to know if the public can accept incentivized organ donation. To evaluate knowledge and opinions on organ donation and compensating the donor/donor family and to determine factors affecting consent. The third survey in 2009 covered 15 regions, 29 provinces, and 14 cities in the National Capital Region. There were 1500 respondents interviewed using a structured questionnaire. Analysis used Statistical Package for Social Science and chi-square. Of the respondents, 63% were females and 74% were married. Nearly half were between 26 and 45 years old. Fewer than 5% were unschooled. Monthly household income was less than USD $222.00 in 70% of respondents. A majority knew about donation from 2001 to 2009. Fewer than 20% knew about deceased donors. Those who wanted to become donors decreased. Sixty-five percent were willing to donate a brain-dead relative's organs. Respondents felt that kidney donors deserve a token of gratitude. Options included livelihood (32%), cash (31%), and educational assistance (26%). Sixty percent wanted the donor assistance termed a "token of gratitude." Consent for donation was positively correlated (P < .05) with higher education and monthly income. Awareness on organ transplantation and donation increased. Factors that promote organ donation are higher education and monthly income. A majority of Filipinos felt that the donor deserves a token of gratitude. Public acceptance of incentivized organ donation may be pursued. Strategies to improve the national advocacy campaign for deceased donation are needed. Copyright © 2012 Elsevier Inc.

An investigation of the impact of prolonged waiting times on blood donors in Ireland.

The aim of this study was to investigate the impact of prolonged queuing times on blood donors, by measuring their satisfaction levels, and positive and negative affects. As donation times have increased over the past number of years within the Irish Blood Transfusion Service, this is an important issue to examine in a climate where voluntary donors are becoming scarce and demands on people's time are increasing. Eighty-five blood donors were sampled from one urban and one rural blood donor clinic. The respondents conducted a questionnaire by means of face-to-face interview, while waiting in the clinic. The questionnaire contained the Positive and Negative Affect Scale (PANAS), and a waiting satisfaction scale. Both actual and perceived waiting times of the donors were noted. Waiting time was found to be negatively related to satisfaction. Inexperienced donors expressed higher levels of negative affect than experienced donors. Urban donors were significantly more satisfied than rural donors. There was a significant difference in perceived waiting time between lone donors and those queuing in a group, with those waiting alone perceiving their wait as shorter. While all respondents stated that they intended to donate again, over one-third stated that prolonged waiting times would be their most likely deterrent. However, only 15% stated that long queuing times might actually prevent them from donating in the future, and almost all respondents said that they would recommend donation to a friend, despite long queuing times. Although our results show that the respondents were not satisfied with current waiting times, it did not seem to affect their future intentions to donate. These findings provide some optimism for the future of blood donation in Ireland, as they suggest a strong sense of commitment to donation within the population sampled. Future research could explore the application of 'the service industry' approach to waiting times to blood donation clinics.

In sub-Saharan Africa improving the deferral of at-risk blood donors would be a cost-effective approach to reducing transfusion-transmitted human immunodeficiency virus (HIV) infections. We performed a pilot case-control study to identify the risk factors for HIV infection and to develop an adapted donor history questionnaire (DHQ) for sub-Saharan Africa. We recruited 137 HIV-positive donors (cases) and 256 HIV-negative donors (controls) and gathered risk factor data using audio computer-assisted self-interview. Variables with univariate associations were entered into a logistic regression model to assess independent associations. A scoring scheme to distinguish between HIV-positive and HIV-negative donors was developed using receiver operating characteristics curves. We identified 16 risk factors including sex with sex worker, past history or treatment for sexually transmitted infections, and having a partner who used injected or noninjected illegal drugs. Two novel risks were related to local behavior: polygamy (odds ratio [OR], 22.7; 95% confidence interval [CI], 5.9-86.7) and medical or grooming treatment on the street (OR, 1.8; 95% CI, 1.0-3.0). Using the 16 selected items the mean scores (>100) were 82.6 ± 6.7 (range, 53.2-95.1) and 85.1 ± 5.2 for HIV-negative donors versus 77.9 ± 6.8 for HIV-positive ones (p = 0.000). Donors who scored between 80 and 90 were more likely to be HIV negative than those who scored less (OR, 31.4; 95% CI, 3.1-313.9). We identified both typical and novel HIV risk factors among Cameroonian blood donors. An adapted DHQ and score that discriminate HIV-negative donors may be an inexpensive means of reducing transfusion-transmitted HIV through predonation screening. © 2017 AABB.

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

What meanings do lesbian couples construct regarding their sperm donor? For some parents, the donor was increasingly presented as a person, whereas for other parents, the donor was seen as an instrument from the moment they received the sperm donation. Few studies specifically focus on how lesbian couples deal with the issue of third-party anonymous gamete donation. It is often assumed that they have fewer difficulties than heterosexual couples with the involvement of a male procreator, since their status as a donor conception family is 'socially visible' and there is no social father who fears exclusion. Semi-structured interviews were conducted with 10 lesbian couples (20 participants), recruited via the Ghent University Hospital. All couples had at least one child, conceived through anonymous donor insemination, between 7 and 10 years old. Within the data corpus, a particular data set was analyzed where couples referred to their donor and his position in their family. Step-by-step inductive thematic analysis was performed resulting in themes that are grounded in the data. All phases of the analysis were followed by team discussion. This study reveals different donor constructs, indicating different ways of dealing with the third-party involvement in the family. Some parents diminish the role of the donor throughout family life and continue to present him as an instrument: something they needed in order to become parents. Others show an increasing interest in the donor as the children mature, which results in a more personalized account of the donor. In our qualitative cross-sectional study, we collected retrospectively constructed stories. Longitudinal qualitative and quantitative research is required to allow for an extrapolation of the conclusions made. This study shows how the concept of the donor is constructed within lesbian families and how it is challenged by the child's developing personality and features. When counseling prospective parents, it could therefore be useful to discuss the concept of the anonymous donor beyond the conception phase. The project was funded by the Research Fund of Ghent University, Belgium. There are no competing interests.

"It's all about trust": reflections of researchers on the complexity and controversy surrounding biobanking in South Africa.

Biobanks are precariously situated at the intersection of science, genetics, genomics, society, ethics, the law and politics. This multi-disciplinarity has given rise to a new discourse in health research involving diverse stakeholders. Each stakeholder is embedded in a unique context and articulates his/her biobanking activities differently. To researchers, biobanks carry enormous transformative potential in terms of advancing scientific discovery and knowledge. However, in the context of power asymmetries in Africa and a distrust in science born out of historical exploitation, researchers must balance the scientific imperative of collecting, storing and sharing high quality biological samples with obligations to donors/participants, communities, international collaborators, regulatory and ethics authorities. To date, researcher perspectives on biobanking in South Africa have not been explored and documented. In-depth qualitative interviews were conducted with a purposive sample of 21 researchers - 8 in the Western Cape, 3 in Gauteng and 10 in Kwa-Zulu Natal. Interviews lasted approximately 40-60 min and were audiotaped with consent. Thematic analysis of the transcribed interviews was conducted by the co-authors. Researchers articulated serious concerns over standardised regulatory approaches that failed to consider the heterogeneity of biobanks. Given that biobanks differ considerably, guidelines and RECs need to stratify risk accordingly and governance processes and structures must be flexible. While RECs were regarded as an important component of the governance structure researchers expressed concern about their expertise in biobanking. Operational management of biobanks was regarded as an ethical imperative and a pre-requisite to building trust during consent processes. While broad general consent was preferred, tiered consent was thought to be more consistent with respect for autonomy and building trust. Material Transfer Agreements (MTAs) were often lacking when biosamples were exported and this was perceived to impact negatively on trust. On the other hand, researchers believed that authentic community engagement would help to build trust. Building trust will best be achieved via a system of governance structures and processes that precede the establishment of a biobank and monitor progress from the point of sample collection through to future use, including export. Such governance structures must be robust and must include comprehensive national legislation, policy and contextualised guidelines. Currently such governance infrastructure appears to be lacking in many African countries including South Africa. Capacity development of all stakeholders including REC members will enhance expeditious and efficient review of biobanking protocols which in turn will reinforce trust in the researcher-donor relationship. Science translation and community engagement in biobanking is integral to the success of biobanking in South Africa.

To explore how patients who are wait-listed for or who have received a kidney transplant understand the current UK kidney allocation system, and their views on ways to allocate kidneys in the future. Qualitative study using semistructured interviews and thematic analysis based on a pragmatic approach. 10 deceased-donor kidney transplant recipients, 10 live-donor kidney transplant recipients, 12 participants currently wait-listed for a kidney transplant and 4 participants whose kidney transplant failed. Semistructured telephone interviews conducted with participants in their own homes across the UK. Three main themes were identified: uncertainty of knowledge of the allocation scheme; evaluation of the system and participant suggestions for future allocation schemes. Most participants identified human leucocyte anitgen matching as a factor in determining kidney allocation, but were often uncertain of the accuracy of their knowledge. In the absence of information that would allow a full assessment, the majority of participants consider that the current system is effective. A minority of participants were concerned about the perceived lack of transparency of the general decision-making processes within the scheme. Most participants felt that people who are younger and those better matched to the donor kidney should be prioritised for kidney allocation, but in contrast to the current scheme, less priority was considered appropriate for longer waiting patients. Some non-medical themes were also discussed, such as whether parents of dependent children should be prioritised for allocation, and whether patients with substance abuse problems be deprioritised. Our participants held differing views about the most important factors for kidney allocation, some of which were in contrast to the current scheme. Patient participation in reviewing future allocation policies will provide insight as to what is considered acceptable to patients and inform healthcare staff of the kinds of information patients would find most useful.

Worldwide, oocyte donors donate voluntarily or receive varying amounts of money for donation. This raises ethical questions regarding the appropriateness of financial compensation, and the possibility of undue inducement and exploitation of oocyte donors. Are these donors capable of making an independent, well-considered decision? Regarding this matter, it is important to examine aspects such as autonomy-connectedness and self-esteem. In this cross-sectional study, demographic characteristics and donation motivations were assessed in 92 women who attended the University Medical Center (UMC) Utrecht as potential oocyte donors between June 2012 and July 2016. Demographic characteristics were assessed. Motivations were recorded in semi-structured interviews (response rate 59%). The Rosenberg Self-Esteem Scale was used to assess level of self-esteem. The Autonomy-Connectedness Scale was used to measure the level of autonomy-connectedness. The typical oocyte donor at the UMC Utrecht is a well-educated, employed, 31-year-old woman living with her partner in a completed family with two children, and donating on altruistic grounds. The donors showed higher autonomy-connectedness scores than the average female Dutch population and do not lack self-esteem (questionnaire response rate 66%). Concerns regarding exploitation and attraction of women with lower socioeconomic status, with shortcomings in autonomy-connectedness and self-esteem, could not be confirmed in this group.

Disclosure of donor conception to children was compared between solo mother and two-parent families with children aged 4-8 years conceived since the removal of donor anonymity in the UK. Semi-structured interviews were conducted with 31 heterosexual solo mothers and 47 heterosexual mothers with partners to investigate their decisions and experiences about identifiable donation and disclosure to their children. No significant difference was found in the proportion of mothers in each family type who had told their children about their donor conception (solo mothers 54.8%; partnered mothers 36.2%). Of those who had not told, a significantly higher proportion of solo mothers than partnered mothers intended to disclose (P < 0.05). Partnered mothers were more likely than solo mothers to feel neutral, ambivalent or negative about having used an identifiable donor (P < 0.05), and were less likely to consider children's knowledge of their genetic origins as extremely important (P < 0.05). These findings are relevant to provision of counselling services as it cannot be assumed that parents will tell their children about their origins or their entitlement to request the identity of their donor at the age of 18 years. Further qualitative research would increase understanding of solo mothers' attitudes towards disclosure. Copyright © 2016 The Authors. Published by Elsevier Ltd.. All rights reserved.

Knowledge of the reasons for donor deferral can help in planning more efficient recruitment strategies and evaluating donor selection criteria. This study aimed to investigate the rates and reasons for donor deferral. Retrospective study at Shiraz Blood Transfusion Center, Shiraz, Iran. 141,820 volunteers were interviewed confidentially by physicians before blood donation. The rate of and reasons for donor deferral were investigated according to demographic characteristics. The data were analyzed using the comparison-of-proportions test of the MedCalc statistical software. 43,839 people (30.9%) who had come for blood donation were deferred, 1,973 (4.5%) of them permanently. The deferral rate was significantly higher among women, single individuals and first-time donors, compared with men, married individuals and those with a history of previous donation (P < 0.0001). The deferral rate was significantly higher in the 17 to 30-year-old group (P < 0.05). The reasons for deferral were divided into five categories: risk factors possibly related to HIV or hepatitis (43.6%), underlying diseases (31.9%), non-eligible conditions (13.5%), medications that interfere with blood donation (7.8%) and risk factors that may relate to bacterial or viral infections except HIV and hepatitis infections (3.2%). Effective measures are required for documenting the impact of deferral on blood availability, monitoring the effectiveness of and need for deferral, and determining the reasons and rates of deferral.

We report our experience with potential donors for living donor liver transplantation (LDLT), which is the first report from an area where there is no legalized deceased donation program. This is a single center retrospective analysis of potential living donors (n = 1004) between May 2004 and December 2012. This report focuses on the analysis of causes, duration, cost, and various implications of donor exclusion (n = 792). Most of the transplant candidates (82.3%) had an experience with more than one excluded donor (median = 3). Some recipients travelled abroad for a deceased donor transplant (n = 12) and some died before finding a suitable donor (n = 14). The evaluation of an excluded donor is a time-consuming process (median = 3 d, range 1 d to 47 d). It is also a costly process with a median cost of approximately 70 USD (range 35 USD to 885 USD). From these results, living donor exclusion has negative implications on the patients and transplant program with ethical dilemmas and an economic impact. Many strategies are adopted by other centers to expand the donor pool; however, they are not all applicable in our locality. We conclude that an active legalized deceased donor transplantation program is necessary to overcome the shortage of available liver grafts in Egypt.

Objectives The aim of this study was to gain insight into how women in same-sex relationships experience the process of forming a family through the use of assisted reproduction technique (ART), from planning the pregnancy to parenthood, and their experience of parental support from healthcare professionals. Methods The participants were 20 women in a same-sex relationship who had conceived through ART at a Swedish clinic. Semi-structured interviews including open questions about pregnancy, parenthood and support from healthcare professionals were conducted. The interviews were tape-recorded and transcribed verbatim. The data were analysed according to grounded theory. Results The core category, A stressful journey through a heteronormative world, emerged from the analysis, as did three subcategories: A journey fraught with difficulties and decisions; The nuclear family as the norm; and A need for psychological support. Same-sex parents expressed a need for more information about how to access ART in Sweden. Both the healthcare organization and treatment were perceived as heteronormative. In particular, these women lacked psychological support during the demanding process of utilizing a sperm donor to conceive. Conclusions for Practice Professionals in antenatal care should undergo mandatory cultural competency training to ensure cultural sensitivity and the provision of updated information, tailored brochures and early parental support for families with same-sex parents. All parents need guidance and support from competent, caring personnel throughout the entire process of forming a family.

To study the potential of CASA parameters in frozen-thawed donor semen before and after preparation on silica gradient as predictors of pregnancy in IUI with donor semen cycles. CASA parameters were measured in thawed donor semen before and after preparation on a silica gradient in 132 couples undergoing 168 IUI cycles with donor semen. The evolution of these parameters throughout this process was calculated. The relationship with cycle outcome was then studied. Clinical pregnancy rate was 18.4% per cycle. CASA parameters on donor semen before or after preparation were not significantly different between pregnancy and failure groups. However, amplitude of lateral head displacement (ALH) of spermatozoa improved in all cycles where pregnancy occurred, thus predicting pregnancy with a sensitivity of 100% and a specificity of 20%. Even if CASA parameters do not seem to predict pregnancy in IUI with donor semen cycles, their evolution during the preparation process should be evaluated, especially for ALH. However, the link between ALH improvement during preparation process and pregnancy remains to be explored. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Deceased organ donation for transplantation: Challenges and opportunities

PubMed Central

Girlanda, Raffaele

2016-01-01

Organ transplantation saves thousands of lives every year but the shortage of donors is a major limiting factor to increase transplantation rates. To allow more patients to be transplanted before they die on the wait-list an increase in the number of donors is necessary. Patients with devastating irreversible brain injury, if medically suitable, are potential deceased donors and strategies are needed to successfully convert them into actual donors. Multiple steps in the process of deceased organ donation can be targeted to increase the number of organs suitable for transplant. In this review, after describing this process, we discuss current challenges and potential strategies to expand the pool of deceased donors. PMID:27683626

The purpose of this research is to explore donors' perspectives on support of nursing excellence in a community hospital. Philanthropic support is rapidly becoming critical to support nursing excellence in hospitals, including continuing education, nursing research, and professional development. However, no research has examined the experience of private donors who support nursing programs in community hospitals. Structured interviews were conducted with individuals with a history of providing significant financial support (gifts >$50 000) targeted specifically for nursing in a 176- bed community hospital in the southeastern United States. Analysis was performed using descriptive content analysis. Four themes emerged that centered around making a difference, helping nurses meet new challenges, an existing foundation of service, and valuing excellent nursing care received. This research provides specific information that nursing administrators can use when seeking philanthropic gifts to support nursing excellence programs in US community hospitals.

Donating embryos to stem cell research.

This paper is based on linked qualitative studies of the donation of human embryos to stem cell research carried out in the United Kingdom, Switzerland, and China. All three studies used semi-structured interview protocols to allow an in-depth examination of donors' and non-donors' rationales for their donation decisions, with the aim of gaining information on contextual and other factors that play a role in donor decisions and identifying how these relate to factors that are more usually included in evaluations made by theoretical ethics. Our findings have implications for one factor that has previously been suggested as being of ethical concern: the role of gratitude. Our empirical work shows no evidence that interpersonal gratitude is an important factor, but it does support the existence of a solidarity-based desire to "give something back" to medical research. Thus, we use empirical data to expand and refine the conceptual basis of bioethically theorizing the IVF-stem cell interface.

Considerable resources have been invested in recent years to improve laboratory systems in resource-limited settings. We reviewed published reports, interviewed major donor organizations, and conducted case studies of laboratory systems in 3 countries to assess how countries and donors have worked together to improve laboratory services. While infrastructure and the provision of services have seen improvement, important opportunities remain for further advancement. Implementation of national laboratory plans is inconsistent, human resources are limited, and quality laboratory services rarely extend to lower tier laboratories (eg, health clinics, district hospitals). Coordination within, between, and among governments and donor organizations is also frequently problematic. Laboratory standardization and quality control are improving but remain challenging, making accreditation a difficult goal. Host country governments and their external funding partners should coordinate their efforts effectively around a host country's own national laboratory plan to advance sustainable capacity development throughout a country's laboratory system.

Prompted by the need to achieve progress in health outcomes, payment for performance (P4P) schemes are becoming popular policy options in the health systems in many low income countries. This paper describes the policy process behind the introduction of a payment for performance scheme in the health sector of Tanzania illuminating in particular the interests of and roles played by the Government of Norway, the Government of Tanzania and the other development partners. The study employed a qualitative research design using in-depth interviews (IDIs), observations and document reviews. Thirteen IDIs with key-informants representing the views of ten donor agencies and government departments influential in the process of introducing the P4P scheme in Tanzania were conducted in Dar es Salaam, Tanzania and Oslo, Norway. Data was collected on the main trends and thematic priorities in development aid policy, countries and actors perceived to be proponents and opponents to the P4P scheme, and P4P agenda setting in Tanzania. The initial introduction of P4P in the health sector of Tanzania was controversial. The actors involved including the bilateral donors in the Health Basket Fund, the World Bank, the Tanzanian Government and high level politicians outside the Health Basket Fund fought for their values and interests and formed alliances that shifted in the course of the process. The process was characterized by high political pressure, conflicts, changing alliances, and, as it evolved, consensus building. The P4P policy process was highly political with external actors playing a significant role in influencing the agenda in Tanzania, leaving less space for the Government of Tanzania to provide leadership in the process. Norway in particular, took a leading role in setting the agenda. The process of introducing P4P became long and frustrating causing mistrust among partners in the Health Basket Fund.

Timing and setting were central issues; women hoped that it would hasten labour, while the home was seen as a setting offering freedom, security and reassurance, as opposed to the hospital, seen as constraining. Two women reported problems with IMN but the remainder reported that they would repeat the experience. women were very positive about the opportunity to undertake cervical ripening at home. It is important to explore this setting further for appropriate interventions. Copyright © 2009 Elsevier Ltd. All rights reserved.

Transgressive ethics: Professional work ethics as a perspective on ‘aggressive organ harvesting’

PubMed Central

Jensen, Anja MB

2013-01-01

Occasionally brain-dead organ donors go into cardiac arrest before reaching the operating theater. In such cases, the needed resuscitation of the potential donor stimulates a range of concerns among the responsible staff. If the intensive care unit staff are going to carry out the organ retrieval, they must rush in with demanding treatment measures such as defibrillation shock and cardiac massage that may break breast bones and make the donor vomit. Such treatment measures conflict with widespread ideals of tranquility in donor care and yet they are currently under consideration in Danish intensive care units. Why is this type of ‘aggressive organ harvesting’, as it is sometimes called, considered a likely development, even to the extent that the interviewed health professionals request a policy prescribing procurement measures they morally deplore? We suggest that to understand this change of treatment norms, we must move close to everyday work practices and appreciate the importance of material–technical treatment options as well as the interplay of professional ethics and identity. The cardiac treatment of brain-dead donors may thereby illuminate how treatment norms develop on the ground and thus can theoretically develop our understanding of the mechanisms associated with increasingly ‘aggressive organ harvesting’.

This nationwide survey investigated the actual practices for supporting and confirming the decision-making involved in related living-organ donations in Japan, focusing on organ type and program size differences. Answers to a questionnaire survey were collected from 89 of the 126 (71%) kidney and 30 of the 35 (86%) liver transplantation programs in Japan that were involved in living-donor transplantations in 2013. In 70% of the kidney and 90% of the liver transplantation programs, all donors underwent "third-party" interviews to confirm their voluntariness. The most common third parties were psychiatrists (90% and 83%, respectively). Many programs engaged in practices to support decision-making by donor candidates, including guaranteeing the right to withdraw consent to donate (70% and 100%, respectively) and prescribing a set "cooling-off period" (88% and 100%, respectively). Most donors were offered care by mental health specialists (86% and 93%, respectively). Third parties were designated by more of the larger kidney transplant programs compared with the smaller programs. In conclusion, the actual practices supporting and confirming the decision to donate a living organ varied depending on the organ concerned and the number of patients in the program. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.

MDCT evaluation of potential living renal donor, prior to laparoscopic donor nephrectomy: What the transplant surgeon wants to know?

Ghonge, Nitin P; Gadanayak, Satyabrat; Rajakumari, Vijaya

2014-01-01

As Laparoscopic Donor Nephrectomy (LDN) offers several advantages for the donor such as lesser post-operative pain, fewer cosmetic concerns and faster recovery time, there is growing global trend towards LDN as compared to open nephrectomy. Comprehensive pre-LDN donor evaluation includes assessment of renal morphology including pelvi-calyceal and vascular system. Apart from donor selection, evaluation of the regional anatomy allows precise surgical planning. Due to limited visualization during laparoscopic renal harvesting, detailed pre-transplant evaluation of regional anatomy, including the renal venous anatomy is of utmost importance. MDCT is the modality of choice for pre-LDN evaluation of potential renal donors. Apart from appropriate scan protocol and post-processing methods, detailed understanding of surgical techniques is essential for the Radiologist for accurate image interpretation during pre-LDN MDCT evaluation of potential renal donors. This review article describes MDCT evaluation of potential living renal donor, prior to LDN with emphasis on scan protocol, post-processing methods and image interpretation. The article laid special emphasis on surgical perspectives of pre-LDN MDCT evaluation and addresses important points which transplant surgeons want to know. PMID:25489130

Abstract Although concerns have historically been raised about the influence of external donors on health policy process in recipient countries, remarkably few studies have investigated perspectives and experiences of domestic policymakers and advisers. This study examines donor influence at different stages of the health policy process (priority setting, policy formulation, policy implementation and monitoring and evaluation) in two aid-dependent LMICs, Cambodia and Pakistan. It identifies mechanisms through which asymmetries in influence between donors and domestic policy actors emerge. We conducted 24 key informant interviews—14 in Pakistan and 10 in Cambodia—with high-level decision-makers who inform or authorize health priority setting, allocate resources and/or are responsible for policy implementation, identifying three routes of influence: financial resources, technical expertise and indirect financial and political incentives. We used both inductive and deductive approaches to analyse the data. Our findings indicate that different routes of influence emerged depending on the stage of the policy process. Control of financial resources was the most commonly identified route by which donors influenced priority setting and policy implementation. Greater (perceived) technical expertise played an important role in donor influence at the policy formulation stage. Donors’ power in influencing decisions, particularly during the final (monitoring and evaluation) stage of the policy process, was mediated by their ability to control indirect financial and political incentives as well as direct control of financial resources. This study thus helps unpack the nuances of donor influence over health policymaking in these settings, and can potentially indicate areas that require attention to increase the ownership of domestic actors of their countries’ health policy processes.

The demand for therapeutic plasma-derived products poses a challenge to blood collection agencies (BCAs). In 2014-2015, the volume of plasma sent for fractionation met 17.7% of Quebec's needs for immunoglobulins. This article aims to offer an exploration of the paths blood donors follow in order to become plasma and platelet donors (PPDs). This analysis is based on semi-structured interviews with 50 PPDs in Quebec, Canada. Our analysis focused on the occurrence of events and the presence of contextual elements identified through: (1) factual data on PPDs; and (2) what PPDs identified as being an influence on their donation experience. This information was synthesized using a typology of trajectories. Six typical trajectories have been distinguished, first by the presence (19/50 respondents) or absence (31/50) of blood donation as a family tradition. Of the latter 31 donors, some pointed instead to inherited family values as having a significant influence on their commitment (11/31). Donors' careers were then distinguished as having started early (34) or late (16). Sub-types then appeared with the addition of other contextual elements, motivation profiles, and circumstances under which the conversion to apheresis donation occurred. Our findings suggest the existence of diversified donor trajectories, and confirm the importance of conducting more in-depth analyses of the sequence of events occurring along PPDs career. BCAs should develop strategies carefully tailored to different potential clienteles if they wish to convert whole blood donors to apheresis donation, and also focus on recruiting and retaining young PPDs. © 2017 The Authors.

The promotion of Human Milk Banks is an important social service. The Human Milk Banks depend on donors, and knowing the profile of donors seems quite important. To study the demographics and lifestyles of the donors, the reasons or influences for donating, and to associate these variables with the length of the donation. This is a descriptive, cross-sectional study conducted on 168 mothers who answered the written questionnaire when they agreed to become donors. 98 (58%) responded to the telephone interview. The mean age was 33.1 ± 4.5 years. Of the total 27.9% lived outside Madrid and 21.4% were immigrants, with 23.7% working full time, 65.3% had a university education, and 96.2% had a stable partner. The main reasons for donating were too much milk (77%), and to help others (75%). The main obstacle was transportation to the Human Milk Bank for 20% of the donors, and for 61% the main reason for terminating donation was due to reaching the end of lactation. A longer donation is associated with: having a term newborn, with birth weight over 1500 g, starting donating early and reconciling the donation to the work situation. The most common donor profile was a young woman, with university education and a stable partner. Having a term new born, starting donating early, and the conciliation with work is associated with longer donations. Milk pick-up at home would make donation easier.

Best practice guidelines for the operation of a donor human milk bank in an Australian NICU.

2007-10-01

Until the establishment of the PREM Bank (Perron Rotary Express Milk Bank) donor human milk banking had not occurred in Australia for the past 20 years. In re-establishing donor human milk banking in Australia, the focus of the PREM Bank has been to develop a formal and consistent approach to safety and quality in processing during the operation of the human milk bank. There is currently no existing legislation in Australia that specifically regulates the operation of donor human milk banks. For this reason the PREM Bank has utilised existing and internationally recognised management practices for managing hazards during food production. These tools (specifically HACCP) have been used to guide the development of Standard Operating Procedures and Good Manufacturing Practice for the screening of donors and processing of donor human milk. Donor screening procedures are consistent with those recommended by other human milk banks operating internationally, and also consistent with the requirements for blood and tissue donation in Australia. Controlled documentation and record keep requirements have also been developed that allow complete traceability from individual donation to individual feed dispensed to recipient and maintain a record of all processing and storage conditions. These operational requirements have been developed to reduce any risk associated with feeding pasteurised donor human milk to hospitalised preterm or ill infants to acceptable levels.

Blood donors experience a temporary reduction in their hemoglobin (Hb) value after donation. At each visit, the Hb value is measured, and a too low Hb value leads to a deferral for donation. Because of the recovery process after each donation as well as state dependence and unobserved heterogeneity, longitudinal data of Hb values of blood donors provide unique statistical challenges. To estimate the shape and duration of the recovery process and to predict future Hb values, we employed three models for the Hb value: (i) a mixed-effects models; (ii) a latent-class mixed-effects model; and (iii) a latent-class mixed-effects transition model. In each model, a flexible function was used to model the recovery process after donation. The latent classes identify groups of donors with fast or slow recovery times and donors whose recovery time increases with the number of donations. The transition effect accounts for possible state dependence in the observed data. All models were estimated in a Bayesian way, using data of new entrant donors from the Donor InSight study. Informative priors were used for parameters of the recovery process that were not identified using the observed data, based on results from the clinical literature. The results show that the latent-class mixed-effects transition model fits the data best, which illustrates the importance of modeling state dependence, unobserved heterogeneity, and the recovery process after donation. The estimated recovery time is much longer than the current minimum interval between donations, suggesting that an increase of this interval may be warranted.

Research suggests that African migrants are often positively predisposed towards blood donation, but are under-represented in participation. A culturally-tailored intervention targeting the African migrant community in Australia was developed and implemented, to enhance knowledge about blood donation, improve attitudes towards donating, increase intentions to donate blood, and increase the number of new African donors in Australia. Four weeks after a targeted campaign, a survey evaluation process commenced, administered face-to-face by bilingual interviewers from the African community in Melbourne and Adelaide, Australia (community survey). The questionnaires covered demographics, campaign awareness, blood donation knowledge and intentions, medical mistrust and perceived discrimination, and were analysed to evaluate changes in knowledge and intention. Sixty-two percent of survey participants (n = 454) reported being aware of the campaign. With increasing campaign awareness, there was a 0.28 increase in knowledge score (p = .005); previous blood donation was also associated with an increased blood donation knowledge score. Blood donation intention scores were not associated with campaign awareness (p = 0.272), but were associated with previous blood donation behaviour and a positive blood donation attitude score. More positive scores on the blood donation attitude measure were associated with increasing blood donation intentions, self-efficacy and campaign awareness (score increases of 0.27, 0.30 and 0.04, respectively, all p<0.05). Data were collected on the ethnicity of new blood donors in six blood collection centres before and after the intervention, and independent of the intervention evaluation survey. These data were also used to assess behavioural changes and the proportions of donors from different countries before and after the survey. There was no difference in the number of new African migrant donors, before and after the intervention. The culturally-relevant marketing campaign was associated with improved blood donation knowledge and attitudes, but there was no short-term change in blood donation intentions or the number of African donors.

Focus on improving access and quality of HIV care and treatment gained acceptance in Ethiopia through the work of the International Training and Education Center for Health. The initiative deployed mobile field-based teams and capacity building teams to mentor health care providers on clinical services and program delivery in three regions, namely Tigray, Amhara, and Afar. Transitioning of the clinical mentoring program (CMP) began in 2012 through capacity building and transfer of skills and knowledge to local health care providers and management. The initiative explored the process of transitioning a CMP on HIV care and treatment to local ownership and documented key lessons learned. A mixed qualitative design was used employing focus group discussions, individual in-depth interviews, and review of secondary data. The participants included regional focal persons, mentors, mentees, multidisciplinary team members, and International Training and Education Center for Health (I-TECH) staff. Three facilities were selected in each region. Data were collected by trained research assistants using customized guides for interviews and with data extraction format. The interviews were recorded and fully transcribed. Open Code software was used for coding and categorizing the data. A total of 16 focus group discussions and 20 individual in-depth interviews were conducted. The critical processes for transitioning a project were: establishment of a mentoring transition task force, development of a roadmap to define steps and directions for implementing the transition, and signing of a memorandum of understanding (MOU) between the respective regional health bureaus and I-TECH Ethiopia to formalize the transition. The elements of implementation included mentorship and capacity building, joint mentoring, supportive supervision, review meetings, and independent mentoring supported by facility-based mechanisms: multidisciplinary team meetings, case-based discussions, and catchment area meetings. The process of transitioning the CMP to local ownership involved signing an MOU, training of mentors, and building capacity of mentoring in each region. The experience shed light on how to transition donor-supported work to local country ownership, with key lessons related to strengthening the structures of regional health bureaus, and other facilities addressing critical issues and ensuring continuity of the facility-based activities.

To identify the demographic characteristics, risk factors and motivations for donating among blood donors with reactive serologic tests for syphilis. Post-donation interviews with syphilis seropositive blood donors improve recruitment and screening strategies. This case-control study compares 75 Venereal Disease Research Laboratory (VDRL) > 8, EIA+ (enzyme immunoassay) and FTA-ABS+ (fluorescent treponemal antibody); 80 VDRL-, EIA+ and FTA-ABS+; and 34 VDRL- and EIA- donors between 2004 and 2009. Donors were assessed by their demographic characteristics, sexual behaviour, history of alcohol and illicit drugs use, and motivations to donate. Donors with VDRL > 8 were more likely to be divorced [AOR = 12·53; 95% confidence interval (CI) 1·30-120·81], to have had more than six sexual partners (AOR=7·1; 95% CI 1·12-44·62) and to report male-male-sex in the past 12 months (AOR=8·18; 95% CI 1·78-37·60). Donors with VDRL-, EIA+ and FTA-ABS+ were less likely to be female (AOR=0·26; 95% CI 0·07-0·96), more likely to be older (AOR=10·2; 95% CI 2·45-42·58 ≥ 39 and <60 years old) and to have had more than six sexual partners in the past 12 months (AOR = 8·37; 95% CI 1·49-46·91). There was no significant difference among groups regarding illicit drugs use; 30·7% (VDRL > 8) and 12·5% (VDRL-, EIA+ and FTA-ABS+) of donors reported that they had been at risk for HIV infection (P = 0·004). One-third of donors came to the blood bank to help a friend or a relative who needed blood. Although donors exposed to syphilis reported and recognised some high risk behaviour, most were motivated by direct appeal to donate blood. Monitoring the risk profile of blood donors can benefit public health and improve blood safety. © 2014 The Authors. Transfusion Medicine © 2014 British Blood Transfusion Society.

Body donation is important for medical education and academic research. However, it is relatively rare in Hong Kong when compared with many Western countries. Comprehensive research has been performed on the motivation for body donation in Western countries; however, there is still insufficient research on body donation in Hong Kong to provide information on how to increase the body-donation rate. To understand the factors involved in the decision to donate one's body, the authors interviewed a registered donor and the daughter of another donor in Hong Kong. The authors interpreted the information collected in light of the available published reports, which mostly focus on body donation in Western countries. Despite the consistency of some demographic factors and motivations between the participants in our study and those investigated in the published reports from Western countries, there are differences in education level and socioeconomic status between the donors in our study and those from Western studies. The authors also suggest that Confucianism and Buddhism in Chinese culture may motivate potential body donors in Hong Kong. Other important factors that influence the body-donation decision may include family members' body donation, registration as organ donors, and good doctor-patient relationships. Although case report studies have their limitations, this study allows us to explore the complexity of events and establish the interconnectivity of factors involved in body donation, which could not be achieved in previous survey-based studies.

Large registries of potential unrelated stem cell donors have been established in order to enable stem cell transplantation for patients without HLA-identical related donors. Donor search is complicated by the fact that the stored HLA information of many registered donors is incomplete. We carried out a project that was aimed to improve chances of patients with ongoing donor searches to find an HLA-matched unrelated donor. For that purpose, we carried out additional donor center-initiated HLA-DRB1 typing of donors who were only typed for the HLA loci A and B so far and were potential matches for patients in need of a stem cell transplant. In total, 8,861 donors were contacted for donor center-initiated HLA-DRB1 typing within 1,089 donor searches. 12 of these donors have donated stem cells so far, 8 thereof for their respective target patients. We conclude that chances of patients with ongoing donor searches to find an HLA-matched unrelated donor can indeed be improved by donor-center initiated typing that is carried out in addition to the standard donor search process. Our results also raise questions regarding the appropriate use of incompletely typed donors within unrelated donor searches. PMID:21625451

Decision Making in Kidney Paired Donation Programs with Altruistic Donors*

2014-01-01

In recent years, kidney paired donation (KPD) has been extended to include living non-directed or altruistic donors, in which an altruistic donor donates to the candidate of an incompatible donor-candidate pair with the understanding that the donor in that pair will further donate to the candidate of a second pair, and so on; such a process continues and thus forms an altruistic donor-initiated chain. In this paper, we propose a novel strategy to sequentially allocate the altruistic donor (or bridge donor) so as to maximize the expected utility; analogous to the way a computer plays chess, the idea is to evaluate different allocations for each altruistic donor (or bridge donor) by looking several moves ahead in a derived look-ahead search tree. Simulation studies are provided to illustrate and evaluate our proposed method. PMID:25309603

A shortage of transplantable organs is a global problem. There are two types of organ donation: living and deceased. Deceased organ donation can occur following neurological determination of death (NDD) or cardiocirculatory death. Donation after cardiocirculatory death (DCD) accounts for the largest increments in deceased organ donation worldwide. Variations in the use of DCD exist, however, within Canada and worldwide. Reasons for these discrepancies are largely unknown. The purpose of this study is to develop, implement, and evaluate a theory-based knowledge translation intervention to provide practical guidance about how to increase the numbers of DCD organ donors without reducing the numbers of standard NDD donors. We will use a mixed method three-step approach. In step one, we will conduct semi-structured interviews, informed by the Theoretical Domains Framework, to identify and describe stakeholders' beliefs and attitudes about DCD and their perceptions of the multi-level factors that influence DCD. We will identify: determinants of the evidence-practice gap; specific behavioural changes and/or process changes needed to increase DCD; specific group(s) of clinicians or organizations (e.g., provincial donor organizations) in need of behaviour change; and specific targets for interventions. In step two, using the principles of intervention mapping, we will develop a theory-based knowledge translation intervention that encompasses behavior change techniques to overcome the identified barriers and enhance the enablers to DCD. In step three, we will roll out the intervention in hospitals across the 10 Canadian provinces and evaluate its effectiveness using a multiple interrupted time series design. We will adopt a behavioural approach to define and test novel, theory-based, and ethically-acceptable knowledge translation strategies to increase the numbers of available DCD organ donors in Canada. If successful, this study will ultimately lead to more transplantations, reducing patient morbidity and mortality at a population-level.

How does the general public view posthumous organ donation? A meta-synthesis of the qualitative literature

PubMed Central

2011-01-01

Background Many individuals are unwilling to become posthumous organ donors, resulting in a disparity between the supply and demand for organ transplants. A meta-synthesis of the qualitative literature was therefore conducted to determine how the general public views posthumous organ donation. Methods Three online databases (PubMed, PsycINFO, Scopus) were searched for articles published between January 1990 and May 2008 using the following search terms: organ donation, qualitative, interview. Eligibility criteria were: examination of beliefs about posthumous organ donation; utilization of a qualitative research design; and publication in an English peer-reviewed journal. Exclusion criteria were examining how health professionals or family members of organ donors viewed posthumous organ donation. Grounded theory was used to identify the beliefs emerging from this literature. Thematically-related beliefs were then grouped to form themes. Results 27 articles from 24 studies met the inclusion criteria and were reviewed. The major themes identified were: religion, death, altruism, personal relevance, the body, the family, medical professionals, and transplant recipients. An altruistic motivation to help others emerged as the most commonly identified motivator for becoming an organ donor, although feeling a sense of solidarity with the broader community and believing that donated organs are put to good use may be important preconditions for the emergence of this motivation. The two most commonly identified barriers were the need to maintain bodily integrity to safeguard progression into the afterlife and the unethical recovery of organs by medical professionals. The influence of stakeholder groups on willingness to become an organ donor was also found to vary by the level of control that each stakeholder group exerted over the donation recovery process and their perceived conflict of interest in wanting organ donation to proceed. Conclusions These findings afford insights into how individuals perceive posthumous organ donation. PMID:21988839

A new trend in research funding has emerged: directed philanthropy, in which the donor plays an active, hands-on role in managing the research by applying a "business model." Although such efforts now represent only a small portion of foundation funding, they have potentially far-reaching implications because (1) the approach of using a business model is being applied more broadly and (2) the success or failure of these efforts may portend the fate of larger translational efforts. The author conducted interviews with Scott Johnson of the Myelin Repair Foundation and Don Listwin of the Canary Foundation in the fall of 2006.

Donor milk is the best alternative for the feeding of preterm newborns when mother's own milk is unavailable. For safety reasons, it is usually pasteurized by the Holder method (62.5°C for 30 min). Holder pasteurization results in a microbiological safe product but impairs the activity of many biologically active compounds such as immunoglobulins, enzymes, cytokines, growth factors, hormones or oxidative stress markers. High-temperature short-time (HTST) pasteurization has been proposed as an alternative for a better preservation of some of the biological components of human milk although, at present, there is no equipment available to perform this treatment under the current conditions of a human milk bank. In this work, the specific needs of a human milk bank setting were considered to design an HTST equipment for the continuous and adaptable (time-temperature combination) processing of donor milk. Microbiological quality, activity of indicator enzymes and indices for thermal damage of milk were evaluated before and after HTST treatment of 14 batches of donor milk using different temperature and time combinations and compared to the results obtained after Holder pasteurization. The HTST system has accurate and simple operation, allows the pasteurization of variable amounts of donor milk and reduces processing time and labor force. HTST processing at 72°C for, at least, 10 s efficiently destroyed all vegetative forms of microorganisms present initially in raw donor milk although sporulated Bacillus sp. survived this treatment. Alkaline phosphatase was completely destroyed after HTST processing at 72 and 75°C, but γ-glutamil transpeptidase showed higher thermoresistance. Furosine concentrations in HTST-treated donor milk were lower than after Holder pasteurization and lactulose content for HTST-treated donor milk was below the detection limit of analytical method (10 mg/L). In conclusion, processing of donor milk at 72°C for at least 10 s in this HTST system allows to achieve the microbiological safety objectives established in the milk bank while having a lower impact regarding the heat damage of the milk.

In the last decade participatory approaches have gained prominence in policy-making, becoming the focus of good policy-making processes. Policy dialogue is recognised as an important aspect of policy-making among several interactive and innovative policy-making models applied in different contexts and sectors. Recently there has been emphasis on the quality of policy dialogue in terms of how it should be conducted to attain participation and inclusiveness. However, there is paucity of evidence on how the context influences policy dialogue, particularly participation of stakeholders. Liberia's context, which is characterised as post-war, highly donor dependent and in recovery from the recent catastrophic Ebola outbreak, provides an opportunity to understand the influence of context on policy dialogue. This was an exploratory study using qualitative methods. Key informant interviews were conducted using an interview guide. A total of 16 interviews were conducted, 12 at the national level and 4 at the sub national level. Data were analysed using inductive thematic content analysis. The respondents felt that the dialogues were a success and involved important stakeholders; however, there were concerns about the improper methodology and facilitation used to conduct them. Opinions among the respondents about the process of generating and selecting the themes for the dialogues were extremely divergent. Both before and during the Ebola outbreak, the context was instrumental in shaping the dialogues according to the issue of focus, requirements for participation and the decisions to be made. Policy dialogues have become a platform for policy discussions and decisions in Liberia. It is a process that is well recognised and appreciated and is highly attributed to the success of the negotiations during the Ebola outbreak. To sustain and strengthen policy dialogues in future, there needs to be proper information sharing through diverse forums and avenues, stakeholders' empowerment and competent facilitation. These will ensure that the process is credible and legitimate.

Increasing the Rate of Living Donor Kidney Transplantation in Ontario: Donor- and Recipient-Identified Barriers and Solutions

Purpose of Review: To hear from living kidney donors and recipients about what they perceive are the barriers to living donor kidney transplantation, and how patients can develop and lead innovative solutions to increase the rate and enhance the experiences of living donor kidney transplantation in Ontario. Sources of Information: A one-day patient-led workshop on March 10th, 2016 in Toronto, Ontario. Methods: Participants who were previously engaged in priority-setting exercises were invited to the meeting by patient lead, Sue McKenzie. This included primarily past kidney donors, kidney transplant recipients, as well as researchers, and representatives from renal and transplant health care organizations across Ontario. Key Findings: Four main barriers were identified: lack of education for patients and families, lack of public awareness about living donor kidney transplantation, financial costs incurred by donors, and health care system-level inefficiencies. Several novel solutions were proposed, including the development of a peer network to support and educate patients and families with kidney failure to pursue living donor kidney transplantation; consistent reimbursement policies to cover donors’ out-of-pocket expenses; and partnering with the paramedical and insurance industry to improve the efficiency of the donor and recipient evaluation process. Limitations: While there was a diversity of experience in the room from both donors and recipients, it does not provide a complete picture of the living kidney donation process for all Ontario donors and recipients. The discussion was provincially focused, and as such, some of the solutions suggested may already be in practice or unfeasible in other provinces. Implications: The creation of a patient-led provincial council was suggested as an important next step to advance the development and implementation of solutions to overcome patient-identified barriers to living donor kidney transplantation.

Adult-to-adult living donor liver transplantation is becoming an alternative to cadaveric transplantation in urgent and elective settings. Donor selection crucially affects donor safety and recipient outcome. To present our algorithm of urgent and elective donor selection. Urgent selection is expeditious and protocol-based. Elective selection permits a comprehensive process. Both include medical, psychosocial and surgical-anatomic evaluations. Liver volumes and vascular anatomy are evaluated with computerized tomographic angiography. Informed consent is obtained after painstaking explanations. Independent institutional committees review and approve all cases. Between July 2003 and June 2004 we evaluated 43 potential live donors for 12 potential recipients (fulminant hepatic failure, n = 5; chronic end-stage liver disease, n = 6; primary graft non-function, n = 1). Thirty-three candidates (76%) were excluded due to blood type incompatibility (n = 14, 42%), incompatible anatomy (n = 8, 24%)--including problematic volume distribution (n = 2) or vascular anatomy (n = 6)--psychosocial issues (n = 4, 12%), or medical co-morbidity (n = 7, 22%). Five recipients (FHF, n = 4; chronic ESLD, n = 1) were successfully transplanted from living donors. In the acute setting, two patients (FHF, PGNF) died in the absence of an appropriate donor (cadaveric or living donor). In the elective group, one patient died of unexpected variceal bleeding and one received a cadaveric graft just before the planned living donor transplantation was performed. One candidate was transplanted overseas and two cases are scheduled. The ratio of compatibility for donation was 34% (10/29) for blood type-compatible candidates. Donor selection for living donor liver transplantation is a complex, labor-intensive multidisciplinary process. Most exclusions are due to blood type incompatibility or anatomic details. Psychosocial aspects of these donations warrant special attention.

Human Amniotic Membrane (AM) transplantation can promote tissue healing and reduce inflammation, tissue scarring and neovascularization. Homa Peyvand Tamin (HPT) tissue bank has focused on manufacturing human cell and tissue based products including AM. The purpose of this study is to evaluate and identify bacterial contamination of AMs that is produced by HPT for several ophthalmic applications. From July 2006 to April 2011, 122 placentas from cesarean sections were retrieved by HPT after obtaining informed consent from the donors. Besides testing donor's blood sample for viral markers, microbiological evaluation was performed pre and post processing. During tissue processing, decontamination was performed by an antibiotic cocktail including; Gentamicin, Ceftriaxone and Cloxacillin. Of 271 cesarean section AM donors who were screened as potential donors, 122 were accepted for processing and assessed for microbiological contamination. Donors' age were between 21 and 41 years (Mean = 27.61 ± 0.24). More than 92% of mothers were in their first or second gravidity with full term pregnancies. The most prevalent organisms were Staphylococci species (72.53%). After processing, contamination rates markedly decreased by 84.62% (p value = 0.013). According to our results, most of bacterial contaminations were related to donation process and the contamination pattern suggests procurement team as a source. Therefore we recommend that regular training programs should be implemented by tissue banks for procurement staff. These programs should focus on improved donor screening and proper aseptic technique for tissue retrieval. We also suggest that tissue banks should periodically check the rate and types of tissue contaminations. These data help them to find system faults and to update processing methods.

Living organ donation becomes more and more important as the number of patients needing organ transplantation is increasing. The University Hospital of Erlangen initiated a survey of living kidney donors to improve the process of living donation. The survey aimed to assess the donor's needs and experiences during the process of living kidney donation. From 2003 to 2014 n=199 living kidney donations were registered at the University Hospital of Erlangen. A total of n=144 living kidney donors (65.3% females, mean age M=58.7 years) participated in the study. In general, the majority of the living kidney donors were satisfied with the process of donation. Almost all of them (98%) confirmed to donate again, if it was possible. A large part of the living kidney donors denied any negative physical or psychological consequences of the donation. However, around 25% reported still physical problems for example wound healing, pain or long-term hypertension. Furthermore, a lack of pre- and post-operative psychological care or a regular medical follow-up care was reported. Thus, clinical practice needs to be further developed to meet the patient's needs. © Georg Thieme Verlag KG Stuttgart · New York.

Role of the independent donor advocacy team in ethical decision making.

2005-09-01

Adult living donor liver transplantation has developed as a direct result of the critical shortage of deceased donors. Recent regulations passed by New York State require transplant programs to appoint an Independent Donor Advocacy Team to evaluate, educate, and consent to all potential living liver donors. Ethical issues surround the composition of the team, who appoints them, and the role the team plays in the process. Critics of living liver donation have questioned issues surrounding motivation and the ability of donors to provide true informed consent during a time of family crisis. This article will address issues surrounding the controversies and discuss how using the team can effectively evaluate and educate potential living liver donors and improve practice to ensure safety of living donors.

Being Sherlock Holmes: the Internet as a tool for assessing live organ donors.

Donor advocacy is a critical feature of live donor transplantation. Donor Advocates and Donor Advocate Teams (DAT) are now routine to the practice of live donor evaluation in the USA. Multidisciplinary in nature, DATs gather both medical and psychosocial information about potential live organ donors and then render a decision as to whether or not these individuals are suitable to participate. Because of the critical ethical and psychosocial concerns about live donation, thorough donor evaluations are essential. Additionally, the information gathered must be accurate, and this requires honest disclosure by the donor candidate. In this paper, we describe how DATs can use various forms of free, public content available on the Internet to aid live donor assessments. In this way, the DAT assumes somewhat of an investigative role; however, this is ethically justified in light of the DAT duty to protect the donor. The protective effect can also spread to the transplant program, in general, when inappropriate donors are excluded from the donation process.

An adequate donor population is of key importance for the entire blood transfusion chain. For good donor management, a detailed overview of the donor database is therefore imperative. This study offers a new description of the donor cycle related to the donor management process. It also presents the outcomes of a European Project, Donor Management IN Europe (DOMAINE), regarding the segmentation of the donor population into donor types. Blood establishments (BEs) from 18 European countries, the Thalassaemia International Federation and a representative from the South-Eastern Europe Health Network joined forces in DOMAINE. A questionnaire assessed blood donor management practices and the composition of the donor population using the newly proposed DOMAINE donor segmentation. 48 BEs in 34 European countries were invited to participate. The response rate was high (88%). However, only 14 BEs could deliver data on the composition of their donor population. The data showed large variations and major imbalances in the donor population. In 79% of the countries, inactive donors formed the dominant donor type. Only in 21%, regular donors were the largest subgroup, and in 29%, the proportion of first-time donors was higher than the proportion of regular donors. Good donor management depends on a thorough insight into the flow of donors through their donor career. Segmentation of the donor database is an essential tool to understand the influx and efflux of donors. The DOMAINE donor segmentation helps BEs in understanding their donor database and to adapt their donor recruitment and retention practices accordingly. Ways to use this new tool are proposed. © 2013 International Society of Blood Transfusion.

Beyond the Billboard: The Facebook-Based Application, Donor, and Its Guided Approach to Facilitating Living Organ Donation.

Living donor solicitation can raise ethical concerns, regardless of the medium used: newspaper, television, pulpit, billboard or Internet. Moving the search for a living donor into the social media realm introduces the risk of unguided and coercive patient narratives as well as decoupling or even total absence of information that could aid the consent process. The Facebook application (app) for living donors, called Donor (restricted to patient use), aims to address these concerns in several ways: (i) by directing the patient's initial appeal to friends and family; (ii) by guiding the patient's narrative; and (iii) by providing a library of clinical, ethical and regulatory information that informs the consent process. In this paper, we explored these features and contrasted them with billboard solicitation activities and current independent social media efforts. We concluded that the proactive ethical design of the Donor app is a permissible way to help satisfy the shortfall of deceased donor livers and kidneys. © Copyright 2016 The American Society of Transplantation and the American Society of Transplant Surgeons.

A Thematic Aperception Test was used with 13 male and 16 female patients who were requesting A.I.D. The following main psychological reactions were found in women: anxiety and depression (fear of rejection by their family and friends; lowering the image of the husband--the donor being considered as a rival), aggression (the narcissistic woman "demands" A.I.D.; the donor is esteemed highly); mother is protective ("true" paternity comes through love of the child and the need to forget the donor). They found, in men: an inability to abandon fertility as lost (with denial of sterility); ambivalence, castration anxiety and a feeling of being excluded from the mother-child symbiosis with later acceptance of loss of fertility and (sometimes excessively) identification with the "mother". Most subjects studied were not intending telling the child about his true origin; because disclosure would be tantamount to transgressing twice over the laws of paternity and the rules against Oedipus behaviour. There is often a great difference between the ways the partners view the matter and inter-relate. We strongly recommend that psychological advice should be taken before treatment with A.I.D. is started.

A multicentric quasi-experimental study was conducted in Delhi, from March 2007 to September 2007, on i) the factors which stimulate the donors to donate blood, ii) major barriers and myths associated with blood donation and iii) clinicians perception of the rational use of blood. The study design included a face-to-face survey, with a pre-tested questionnaire paper in two leading blood banks of Delhi and by relevant interviewers from the community and medical fraternity. The sample size was 240-blood donors from two different blood banks and the control group included 100 potential donors from community and 50 clinicians from various hospitals. The data generated was analyzed using excel sheet and Epi-Info software. The study revealed the factors which influence the blood donation included replacement credit and family/peer pressure. Regarding myths and barriers, among potential donors, about a quarter of them felt that it is time consuming, and 20% felt it could lead to sexual impairment or is not rewarding. A total of 10% were not aware about the blood donation while 15% said that donation time was inconvenient. Of the 50 clinicians, a quarter of them were not aware of the rational use of blood.

Financial considerations in living organ donation.

PubMed

Jacobs, Cheryl; Thomas, Charlie

2003-06-01

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

Heart transplant remains the definitive therapy for advanced heart failure patients but is limited by organ availability. We identified a large number of donor hearts from our organ procurement organization (OPO) being exported to other regions. We engaged a multidisciplinary team including transplant surgeons, cardiologists, and our OPO colleagues to identify opportunities to improve our center-specific organ utilization rate. We performed a retrospective analysis of donor offers before and after institution of a novel review process. Each donor offer made to our program was reviewed on a monthly basis from July 2013 to June 2014 and compared with the previous year. This review process resulted in a transplant utilization rate of 28% for period 1 versus 49% for period 2 (P = .007). Limiting the analysis to offers from our local OPO changed our utilization rate from 46% to 75% (P = .02). Transplant volume increased from 22 to 35 between the 2 study periods. Thirty-day and 1-year mortality were unchanged over the 2 periods. A total of 58 hearts were refused by our center and transplanted at other centers. During period 1, the 30-day and 1-year survival rates for recipients of those organs were 98% and 90%, respectively, comparable with our historical survival data. The simple process of systematically reviewing donor turndown events as a group tended to reduce variability, increase confidence in expanded criteria for donors, and resulted in improved donor organ utilization and transplant volumes.

The past few decades have seen a resurgence of interest in leukapheresis products to improve the survival of infected patients with neutropenia. These products have a short shelf life and require donor stimulation with dexamethasone before collection. Additionally, a system with good communications and logistical support is essential. A recent survey of blood centers in North America revealed that the majority of centers collecting leukapheresis products use steroid-stimulated donors. The survey results suggested that an analysis of the process and potential process improvement would be of interest to the transfusion medicine community. Data from 2008 to 2011 regarding donor selection, donor dexamethasone stimulation, leukapheresis collection, and correlations between potentially pertinent variables for process improvement were analyzed. Results from an analysis of cost are also included. We evaluate 432 leukapheresis donations and demonstrate correlations between 1) pre- and poststimulation white blood cell (WBC) count (p<0.0001), 2) interval (donor stimulation to collection) and poststimulation WBC count (p<0.0001), and 3) poststimulation WBC count and leukapheresis product granulocyte yield (p<0.0001). Significant improvement in granulocyte quality and yield can be accomplished in dexamethasone-stimulated donors, by selecting eligible donors with relatively high normal prestimulation WBC counts and/or previously good responses to dexamethasone, increasing the duration between dexamethasone stimulation and granulocyte collection, and maintaining optimal hematocrit (5%-10%) in granulocyte collections. Because the majority of surveyed blood centers collecting stimulated granulocytes use steroids alone, modifications presented here may prove useful. Further assessment of correlation between granulocyte yield and clinical outcome will await results of additional studies. © 2012 American Association of Blood Banks.

To describe the recalled medical history, clinical manifestations, and treatment of yaws and syphilis by syphilis seroreactive blood donors in Kumasi, Ghana. Of the blood donors at Komfo Anokye Teaching Hospital, Kumasi, Ghana tested with the syphilis rapid diagnostic test (RDT) and later by rapid plasma reagin (RPR) test, 526 were seroreactive. Four hundred and seventy-one (89.5%) of these subjects were confirmed with the Ortho-Vitros Syphilis TP test as the gold standard and were interviewed to determine past or present clinical manifestations of yaws and syphilis. Of the 471 respondent donors, 28 (5.9%) gave a history of skin lesions and sores; four (14.3%) of these subjects, who were all male and RPR-positive, recalled a diagnosis of syphilis. All four reported having had skin lesions/bumps with slow-healing sores, but only one of them had had these symptoms before the age of 15 years. A small proportion of confirmed seroreactive donors in this sample had any recall of symptoms or treatment for yaws or syphilis. These data suggest that clinical questioning adds little further information to the current screening algorithm. The relative contribution of yaws and syphilis to frequent positive tests in endemic areas remains speculative. Copyright © 2016 The Author(s). Published by Elsevier Ltd.. All rights reserved.

In 2007, previous syphilis infection was diagnosed in a blood donor who had given blood regularly for 15 years. This was discovered when the donor was tested for syphilis, as a new donor in another blood bank. The time of infection is unknown. An expert group, set up by The Norwegian Directorate of Health, was commissioned to evaluate the risk of syphilis transmission through blood products in Norway. The expert group based its evaluation on the epidemiology of syphilis, risk of infection and properties of the syphilis bacterium, especially in relation to blood donation. Specific information about the actual incident, made available by the Norwegian Directorate of Health, was also evaluated. Of 54 blood recipients 21 were alive and 18 (86 %) were tested for syphilis, all with a negative result. For 11 deceased the hospital records were studied without discovering signs of syphilis infection. The risk of transfusion-transmitted syphilis is low for several reasons: The prevalence of syphilis in the population is low, a compulsory interview and completion of a questionnaire before donation in Norway excludes patients who are ill or at risk of being infected; the proportion of fresh blood donations is very low and syphilis bacteria die quickly during normal storage conditions for blood. An incidental infection is symptomatic and easily treated by antibiotics. The expert group recommends to not start syphilis testing of each blood donor but to continue the present routine testing of new donors.

Safe male circumcision in Botswana: Tension between traditional practices and biomedical marketing

Botswana has been running Safe Male Circumcision (SMC) since 2009 and has not yet met its target. Donors like the US Centers for Disease Control and Prevention and Africa Comprehensive HIV/AIDS Partnership (funded by the Gates Foundation) in collaboration with Botswana's Ministry of Health have invested much to encourage HIV-negative men to circumcise. Demand creation strategies make use of media and celebrities. The objective of this paper is to explore responses to SMC in relation to circumcision as part of traditional initiation practices. More specifically, we present the views of two communities in Botswana on SMC consultation processes, implementation procedures and campaign strategies. The methods used include participant observation, in-depth interviews with key stakeholders (donors, implementers and Ministry officials), community leaders and men in the community. We observe that consultation with traditional leaders was done in a seemingly superficial, non-participatory manner. While SMC implementers reported pressure to deliver numbers to the World Health Organization, traditional leaders promoted circumcision through their routine traditional initiation ceremonies at breaks of two-year intervals. There were conflicting views on public SMC demand creation campaigns in relation to the traditional secrecy of circumcision. In conclusion, initial cooperation of local chiefs and elders turned into resistance. PMID:25866013

Since 1994, oocyte donation in France must be organized anonymously, in compliance with the bioethics law. The donation is free and any publicity to enrol donors is forbidden. In this system, the recipients are encouraged to incite a donor to visit the recipient's fertility unit. These donors are called "symbolic" donors, since they allow the recipient to be entitred to receive oocytes from another anonymous donor. According to the law, this procedure can be performed both anonymously and non-anonymously. We wanted to study the implication of the anonymous system, focusing on the secret of the child's conception and on the relationship between the recipient family and the "symbolic" donor. We contacted all the patients (n=83) who had children with oocyte donation in our center between 1988 and 1998. These patients participated in an interview conducted with a standardized questionnaire. Fourteen (17.8%) of the couples were lost to follow-up and three declined to participate. Five recipient couples preferred a non-anonymous donation. In all, 70% of the couples had not yet told their child about the donation. They had mentioned the IVF but not the donation despite of the fact that 50% of symbolic donors came from the family of the recipients, 34% from their friends, or 6% from their professional environment; 10% were not related to the recipients. Long after the child's birth, 25% of the recipients had no contact with the symbolic donor but 41% had selected her as the child's godmother and 15% of symbolic donors were the first to be informed of the birth of the child. After the donation, a gift was offered to the "symbolic" donor by 57% of couples, 33% did not know how to thank them (retribution is forbidden by law) and 10% of couples mentioned that their donor refused any gift. Concerning the donor whose oocytes were used, 63% of recipients did not want to know anything about her. 20% would have liked to have medical information and 13% would like to have all kind of information about her. Only 2% of recipients would have liked to know her identity and 2% would have liked to meet her. In agreement with earlier reports in the literature, the majority (70%) of the parents did not inform their child about the oocyte donation even though the symbolic donor was in contact with the child (being his aunt or his godmother for example). The French system has created a double debt: one related to the real donor and another related to the symbolic donor. In the long run, the parents have found a way to humanize this technique: they have given a symbolic place of godmother to the volunteer donor.

Getting to the Heart of Being the Match: A Qualitative Analysis of Bone Marrow Donor Recruitment and Retention Among College Students

Introduction For those with certain blood or bone cancers, bone marrow donation can mean the difference between life and death. The National Marrow Donor Program® (NMDP) operates the largest bone marrow registry of potential donors; however, at times when potential matches are identified, many donors opt not to donate. The purpose of this study was to describe perspectives from college-aged students on recruitment to a bone marrow donation registry and retention to the registry/follow-through with the donation process. Methods Researchers employed a one-time qualitative study using 7 focus groups comprised of 10 – 11 college students each (n = 76). Results Results yielded three overarching themes: donor recruitment, donor retention, and factors contributing to the overall donation process. More specifically, this study identified key factors affecting bone marrow donation in an essential population: facilitators, barriers, knowledge, and ‘goodness’. Additionally, marketing and communication were found to be major determinants of potential donors staying with the NMDP. Conclusion Better explanations and awareness/promotion campaigns are necessary for recruiting potential donors to the NMDP and to increase the likelihood that the donor will follow through with the donation should a potential match be identified. Recommendations from this study may improve recruitment and retention rates among the NMDP campaigns targeting college students. PMID:25632376

Microparticle content of platelet concentrates is predicted by donor microparticles and is altered by production methods and stress.

In circulation, shedding of microparticles from a variety of viable cells can be triggered by pathological activation of inflammatory processes, by activation of coagulation or complement systems, or by physical stress. Elevated microparticle content (MPC) in donor blood might therefore indicate a clinical condition of the donor which, upon transfusion, might affect the recipient. In blood products, elevated MPC might also represent product stress. Surprisingly, the MPC in blood collected from normal blood donors is highly variable, which raises the question whether donor microparticles are present in-vivo and transfer into the final blood component, and how production methods and post-production processing might affect the MPC. We measured MPC using ThromboLUX in (a) platelet-rich plasma (PRP) of 54 apheresis donors and the corresponding apheresis products, (b) 651 apheresis and 646 pooled platelet concentrates (PCs) with plasma and 414 apheresis PCs in platelet additive solution (PAS), and (c) apheresis PCs before and after transportation, gamma irradiation, and pathogen inactivation (N = 8, 7, and 12 respectively). ThromboLUX-measured MPC in donor PRP and their corresponding apheresis PC samples were highly correlated (r = 0.82, P = .001). The average MPC in pooled PC was slightly lower than that in apheresis PC and substantially lower in apheresis PC stored with PAS rather than plasma. Mirasol Pathogen Reduction treatment significantly increased MPC with age. Thus, MPC measured in donor samples might be a useful predictor of product stability, especially if post-production processes are necessary. Copyright © 2016 The Authors. Published by Elsevier Ltd..

The Motivation Crowding-out Theory suggests that incentives undermine intrinsic motivation and thus blood donation behavior. While there is strong evidence showing the negative relationship between monetary incentives and blood donation, findings on the effect of nonmonetary incentives are mixed. Set in a voluntary, nonremunerated environment, this study explores aspects of the nonmonetary incentive-blood donation relationship not captured by the crowding-out hypothesis. In-depth interviews were conducted to explore donors' attitudes toward nonmonetary incentives currently used or considered by the Australian Red Cross Blood Service (Blood Service). Transcripts were analyzed using an inductive, thematic approach. Of the nonmonetary incentives examined (i.e., health screening tests, branded tokens, paid time off work, recognition of key milestones, and postdonation refreshments), none were found to crowd out intrinsic motivation, although not all were viewed favorably. Donors who viewed branded tokens negatively considered the cost implications for the Blood Service, while donors who responded positively considered the public benefit of tokens in raising the profile of the Blood Service. Other nonmonetary incentives-paid time off work, postdonation refreshments, and health screening tests-were viewed positively because donors perceived them to be congruent to the effort expended in donating blood. Finally, donors expressed a preference for private over public recognition when acknowledging significant contributions. When operating in a voluntary, nonremunerated environment, blood services should view donors as supply partners rather than customers, only consider nonmonetary incentives that are congruent with the act of donation, and provide private rather than public recognition of key milestones. © 2012 American Association of Blood Banks.

Why do policies change? Institutions, interests, ideas and networks in three cases of policy reform

2016-01-01

Abstract Policy researchers have used various categories of variables to explain why policies change, including those related to institutions, interests and ideas. Recent research has paid growing attention to the role of policy networks—the actors involved in policy-making, their relationships with each other, and the structure formed by those relationships—in policy reform across settings and issues; however, this literature has largely ignored the theoretical integration of networks with other policy theories, including the ‘3Is’ of institutions, interests and ideas. This article proposes a conceptual framework integrating these variables and tests it on three cases of policy change in Burkina Faso, addressing the need for theoretical integration with networks as well as the broader aim of theory-driven health policy analysis research in low- and middle-income countries. We use historical process tracing, a type of comparative case study, to interpret and compare documents and in-depth interview data within and between cases. We found that while network changes were indeed associated with policy reform, this relationship was mediated by one or more of institutions, interests and ideas. In a context of high donor dependency, new donor rules affected the composition and structure of actors in the networks, which enabled the entry and dissemination of new ideas and shifts in the overall balance of interest power ultimately leading to policy change. The case of strategic networking occurred in only one case, by civil society actors, suggesting that network change is rarely the spark that initiates the process towards policy change. This analysis highlights the important role of changes in institutions and ideas to drive policymaking, but hints that network change is a necessary intermediate step in these processes.

Donor organ quality affects long term outcome after renal transplantation. A variety of prognostic molecular markers is available, yet their validity often remains undetermined. A network-based molecular model reflecting donor kidney status based on transcriptomics data and molecular features reported in scientific literature to be associated with chronic allograft nephropathy was created. Significantly enriched biological processes were identified and representative markers were selected. An independent kidney pre-implantation transcriptomics dataset of 76 organs was used to predict estimated glomerular filtration rate (eGFR) values twelve months after transplantation using available clinical data and marker expression values. The best-performing regression model solely based on the clinical parameters donor age, donor gender, and recipient gender explained 17% of variance in post-transplant eGFR values. The five molecular markers EGF, CD2BP2, RALBP1, SF3B1, and DDX19B representing key molecular processes of the constructed renal donor organ status molecular model in addition to the clinical parameters significantly improved model performance (p-value = 0.0007) explaining around 33% of the variability of eGFR values twelve months after transplantation. Collectively, molecular markers reflecting donor organ status significantly add to prediction of post-transplant renal function when added to the clinical parameters donor age and gender.

HIV test-seeking behavior among blood donors has been observed worldwide and may pose a threat to the safety of the blood supply. We evaluated current test-seeking motivations and prior alternative HIV testing experiences among blood donors in São Paulo, Brazil. All candidate or potential blood donors were consecutively approached and recruited to participate in the study upon presentation at Fundação Pró-Sangue Hemocentro, the largest blood bank in Brazil. Participants were recruited between August 2012 and May 2013 after they were screened for donor eligibility. Questionnaires were administered through audio computer-assisted self-interview. Among 11,867 donors, 38 % previously tested for HIV apart from blood donation, of whom 47.7 % tested at public facilities and 2.7 % acknowledged getting tested for HIV as the primary reason for donating. Dissatisfaction with prior alternative testing experience was reported by 2.5 % of donors. Current test-seeking motivation was associated with dissatisfaction with prior alternative testing experience and testing at a public alternative facility. The most common reasons for dissatisfaction were too long of a wait to get tested and for results, counseling was too long, lack of privacy, and low confidence in the equipment and accuracy of the test. Lack of awareness about the availability of free and confidential public HIV testing services as well as dissatisfaction with past HIV testing and counseling experiences motivate some individuals to test at blood banks. Test-seeking behavior among blood donors may be best addressed by improving alternative testing programs, particularly with respect to time delays, privacy and perceptions about test accuracy. Educational campaigns on safe blood donation and HIV testing for diagnosis, risk counseling and referral to care are also needed for the general public and for health care providers.

The supply of blood cell products required from the National French Blood Institute (Établissement français du sang [EFS]) relies upon regular blood donors. Contact with donors, tailored to individuals as much as possible, helps them to donate on a regular basis. To communicate as efficiently as possible, the content of the mailings has to be adapted to individuals, each according to his/her motivation and the way he or she perceives and processes the information. Within the context of a research program conducted with the Psychology Department of the University of Caen Basse-Normandie, persuasive theoretical models from social psychology have been tested. These models allow adapting messages according to various combinations of types of information processing, motivations and content of the messages. Different types of mailing invitations have been sent to 1987 donors from the Normandy database, requesting them to donate blood. Every experimental letter worked better than the standard EFS letter (which was used as the "control" letter) in terms of effective blood donation after reception of the letter. Some of the letters are more efficient in motivating donors than others. When the systematic type of processing (deep and thorough processing) is activated it appears important to supply elaborate content. On the contrary, when a heuristic type of processing (fast and superficial) is activated, adaptation of the content is less essential. Last but not least, the nearness of the last blood donation plays a key role. Copyright © 2011 Elsevier Masson SAS. All rights reserved.

Screening blood donors for human immunodeficiency virus antibody: cost-benefit analysis.

PubMed Central

Eisenstaedt, R S; Getzen, T E

1988-01-01

The costs and benefits of screening blood donors for antibody to human immunodeficiency virus (HIV) are assessed. Total costs, including testing, discarding processed blood, marginal donor recruiting, notifying and evaluating positive donors, are $36,234,000 annually for 10 million donors in 1986. Screening these donors will prevent 292 cases of transfusion-transmitted acquired immune deficiency syndrome (TT-AIDS), saving the costs of therapy and loss of earnings for total benefits of $43,490,480, a benefit:cost ratio of 1.2:1. Net economic benefits of $0.73 per donor will arise from the program. Calculated benefits will rise as increased numbers of infected recipients are diagnosed with longer follow-up or as partially effective therapy increases the cost of caring for patients with AIDS. Changes in test sensitivity, follow-up procedures, estimated value of life, and testing costs will also alter these projections, but none as dramatically as a change in the overall specificity of the screening process. The cost per case of TT-AIDS prevented, $124,089, and cost per year of life extended, $10,885, are comparable to costs of other screening programs. PMID:3126676

The distributions of hydrogen-containing donors in Ge{sub 1–x}Si{sub x} (0 ≤ x ≤ 0.06) alloys implanted with hydrogen ions with an energy of 200 and 300 keV and a dose of 1 × 10{sup 15} cm{sup –2} are studied. It is established that, at the higher ion energy, the limiting donor concentration after postimplantation heat treatment (275°C) is attained within ~30 min and, at the lower energy, within ~320 min. In contrast to donors formed near the surface, a portion of hydrogen-containing donors formed upon the implantation of ions with the higher energy possess the property of bistability. The limitingmore » donor concentration is independent of the ion energy, but decreases from 1.3 × 10{sup 16} to 1.5 × 10{sup 15} cm{sup –3}, as the Si impurity content in the alloy is increased from x = 0.008 to x = 0.062. It is inferred that the observed differences arise from the participation of the surface in the donor formation process, since the surface significantly influences defect-formation processes involving radiation-induced defects, whose generation accompanies implantation.« less

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

The beneficial effects of breastfeeding for mothers and babies are well recognized. When maternal breast milk is not available in sufficient quantity, donor breast milk is recommended as an alternate source of nutrition, particularly in preterm and other high-risk infants. Australia lags behind the rest of the developed world in establishing and promoting human milk banks; there is no human milk bank in South Australia and little is known concerning mothers' perceptions of using human milk banks in that state. This study explored mothers' knowledge of and attitudes toward human milk banks, to inform the development of human milk banking policies and guidelines in South Australia should a milk bank be established. In-depth semistructured interviews were conducted with 12 mothers who were breastfeeding and/or had preterm or sick babies. In addition, 2 focus groups were conducted-1 with breastfeeding mothers as potential donors (n = 5) and the other with mothers of preterm or high-risk infants (n = 4)-to answer questions raised by early analysis of the individual interview data. Breastfeeding mothers, as potential donors, unanimously supported donating their breast milk to a human milk bank, provided it would be easy (especially if required to drop off milk) and not overly time consuming. Mothers of preterm or sick infants would use a human milk bank if they were assured the milk was safe and appropriate for their babies. Study participants would welcome having access to a human milk bank for both donating and receiving milk in South Australia.

Current organ supply system depends on altruistic noncoercive donation, which has failed to meet the demand of organ transplantation. Providing financial incentives to donors is one of several approaches to address organ shortage. However, its feasibility is debatable as it relates to medical, ethical, and economic dimensions. An incentive-based procurement system (IBPS) applied by the Mobile Donor Action Team (MDAT) was instituted in Riyadh, Saudi Arabia, resulting in a 3-fold increase in donation rate. The goal of this study was to provide a qualitative review of a 7-year experience with IBPS. A qualitative approach was used. Documents were reviewed to create a chronological audit and shape interview questions. Sampling was purposeful and inclusive of MDAT members. Semi-structured interviews were conducted, and findings were subjected to thematic analysis. Documents reflected the evolution of MDAT. The essence of MDAT is field work and liberal use of financial incentives, which resulted in a 3-fold increase in the donation rate. MDAT members believed that IBPS is the main reason behind this increase. Moreover, IBPS is viewed as acceptable from a moral, ethical, and religious standpoint, with a high degree of professional satisfaction. Theoretical assumptions doubted the feasibility of IBPS. This real-life experience with IBPS proved the contrary. The findings may be applicable only to the setting in Riyadh, Saudi Arabia, however; further research is thus needed to explore its transferability to other settings. IBPS may be an alternative to altruistic noncoercive donation and should be piloted in different settings. Copyright © 2014 Elsevier Inc. All rights reserved.

Two mothers and a donor: exploration of children’s family concepts in lesbian households

PubMed Central

Raes, I.; Van Parys, H.; Provoost, V.; Buysse, A.; De Sutter, P.; Pennings, G.

2015-01-01

Background: Although children from lesbian families appear to make a distinction between a residential father and a donor, defining these two concepts seems to be a challenge. They need to appeal to more familiar concepts such as the hetero-normative concept of ‘mother’ to give a definition of the unfamiliar concepts they are confronted with. Methods: The study is based on qualitative in-depth interviews with 6 children (9-10 years old) from lesbian families, all of which have been conceived using anonymous sperm donation. Semi-structured interviews were conducted. Results: Two findings stand out. First, in defining the concepts of biological and non-biological mother, both mothers were described as equal parents. No difference was attached by the children to the mothers’ position as a parent. Second, the concepts ‘non-biological mother’ and ‘donor’ were defined by looking at the hetero-normative concepts of ‘mummy’ and ‘daddy’. To define the non-biological mother, both a ‘mummy’ and a ‘daddy’ were used as a reference. To define the donor concept, often references were made to a daddy. This comparison with a ‘daddy’ turned out to be complex due to the conflict between the role as a progenitor and the lack of a social relationship. The lack of language surrounding this concept turned out to be difficult. Wider implications of the findings: This study illustrates the complexity and ambiguity of children‘s experiences and perceptions when dealing with issues related to genetic and social parenthood.

The influence of the donor-recipient relationship on related donor reactions to stem cell donation.

PubMed

Labott, S; Pfammatter, A

2014-06-01

Previous research has begun to delineate the complicated reactions experienced by bone marrow and stem cell donors. The purpose of this study was to examine the influence of the donor-recipient relationship on the related donor's emotional reactions. Twenty-eight adult stem cell donors completed questionnaires before donation, 30 days post stem cell infusion, and 1 year after infusion. Questionnaires addressed the donor-recipient relationship, depression, mood, guilt and responsibility, self-esteem, ambivalence about donation and reactions to the donation itself. Results indicated that most donors reported little ambivalence about donation, and their reactions to the donation itself were generally positive. Closer and more positive donor-recipient relationships were associated with less anticipated guilt and responsibility if the transplant did not work. The relationships between the donor and the recipient did not change over time. Mood disturbance and depression were low overall, not related to the donor-recipient relationship, and did not significantly change over time. These results indicate that related stem cell donors are generally without significant emotional distress, and are comfortable with the donation process. Further, a more positive relationship with the recipient may help donors to avoid feeling guilty and responsible if the transplant does not work.

Razdan, Manik; Degenholtz, Howard B; Kahn, Jeremy M; Driessen, Julia

2015-01-01

Background. This study examines the effect of breakdown in the organ donation process on the availability of transplantable organs. A process breakdown is defined as a deviation from the organ donation protocol that may jeopardize organ recovery. Methods. A retrospective analysis of donation-eligible decedents was conducted using data from an independent organ procurement organization. Adjusted effect of process breakdown on organs transplanted from an eligible decedent was examined using multivariable zero-inflated Poisson regression. Results. An eligible decedent is four times more likely to become an organ donor when there is no process breakdown (adjusted OR: 4.01; 95% CI: 1.6838, 9.6414; P < 0.01) even after controlling for the decedent's age, gender, race, and whether or not a decedent had joined the state donor registry. However once the eligible decedent becomes a donor, whether or not there was a process breakdown does not affect the number of transplantable organs yielded. Overall, for every process breakdown occurring in the care of an eligible decedent, one less organ is available for transplant. Decedent's age is a strong predictor of likelihood of donation and the number of organs transplanted from a donor. Conclusion. Eliminating breakdowns in the donation process can potentially increase the number of organs available for transplant but some organs will still be lost.

Corneal donations do not fill the transplant demand. The waiting list had 5512 individuals in Brazil and 143 in Rio Grande do Sul in December 2012. The aim of this study was to identify the reasons for family refusal of ocular tissues donation. This retrospective study analyzed interview records for ocular tissue procurement performed in a general, public university hospital located in Southern Brazil between January 2008 and December 2012. It identified the reasons of family refusal for ocular tissue donation. A total of 1010 interviews for ocular tissues procurement were performed. From these, 513 (50.79%) refused donation with the following reasons: 60 (11.69%) family members were unaware of the desire of the potential donor, 153 (29.82%) of potential donors spoke against donation in life, 113 (22.02%) family members were undecided about the donation, 156 (30.40%) family members were against donation, 3 (0.58%) family members were unhappy with the service, 11 (2.14%) family members were afraid of body release delay, 6 (1.16%) families expressed religious convictions against donation, and 11 (2.14%) family members wanted to keep the body intact. There are many reasons for ocular tissues donation refusal, and the knowledge provides better strategies for family interviews. In this study, most of the reasons, around 90%, can be related to lack of information or communication about the subject. Greater awareness of the population about the subject can be a good way to increase ocular tissue procurement indexes. Copyright © 2014 Elsevier Inc. All rights reserved.

Skin graft is a standard therapeutic technique in patients with deep ulcers, but managing donor site after grafting is very important. Although several modern dressings are available to enhance the comfort of donor site, using techniques that accelerate wound healing may enhance patient satisfaction. Low-level laser therapy (LLLT) has been used in several medical fields, including healing of diabetic, surgical, and pressure ulcers, but there is not any report of using this method for healing of donor site in burn patients. The protocols and informed consent were reviewed according to Medical Ethics Board of Shahid Beheshti University of Medical Sciences (IR.SBMU.REC.1394.363) and Iranian Registry of Clinical Trials (IRCT2016020226069N2). Eighteen donor sites in 11 patients with grade 3 burn ulcer were selected. Donor areas were divided into 2 parts, for laser irradiation and control randomly. Laser area was irradiated by a red, 655-nm laser light, 150 mW, 2 J/cm 2 , on days 0 (immediately after surgery), 3, 5, and 7. Dressing and other therapeutic care for both sites were the same. The patients and the person who analyzed the results were blinded. The size of donor site reduced in both groups during the 7-day study period (P < 0.01) and this reduction was significantly greater in the laser group (P = 0.01). In the present study, for the first time, we evaluate the effects of LLLT on the healing process of donor site in burn patients. The results showed that local irradiation of red laser accelerates wound healing process significantly.

Organs donated from persons born outside Spain are becoming increasingly numerous. These persons now account for 26.1% of all donors in the "Malaga sector," an area of tourism with a high percentage of immigrants. Acceptance to donation among persons from Europe and South America is similar to that of Spanish persons but lower among those born in Africa. We must recognize the great help that cultural mediators provided not only by assistance with the language barrier but also by generating confidence among families and understanding their emotions, feelings, and traditions, mainly during interviews with families from different social and cultural miliere. To be efficient, the interpreters or cultural mediators need to have received specific training in the organ donation process and to be involved and convinced that organ donation and transplantation is the best solution for severe health problems.

Herein, we theoretically and experimentally investigated the mechanisms of charge separation processes of organic thin-film solar cells. PTB7, PTB1, and PTBF2 have been chosen as donors and PC 71 BM has been chosen as an acceptor considering that effective charge generation depends on the difference between the material combinations. Experimental results of transient absorption spectroscopy show that the hot process is a key step for determining external quantum efficiency (EQE) in these systems. From the quantum chemistry calculations, it has been found that EQE tends to increase as the transferred charge, charge transfer distance, and variation of dipole moments between the ground and excited states of the donor/acceptor complexes increase; this indicates that these physical quantities are a good descriptor to assess the donor-acceptor charge transfer quality contributing to the solar cell performance. We propose that designing donor/acceptor interfaces with large values of charge transfer distance and variation of dipole moments of the donor/acceptor complexes is a prerequisite for developing high-efficiency polymer/PCBM solar cells.

Optoelectronic Properties of Conjugated Block Copolymer with Flexible Linking Group

NASA Astrophysics Data System (ADS)

Hu, Zhiqi; Verduzco, Rafael

State-of-the-art organic photovoltaics (OPVs) are prepared by depositing a disordered, co-continuous donor and acceptor blend. While optimization of material processing has produced significant improvements in performance, a fundamental understanding of charge separation and recombination at the donor/acceptor interface is lacking. Block copolymers with donor and acceptor polymer blocks provide an opportunity for controlling the donor-accepter interfacial structure and understanding its relationship to charge separation and photovoltaic performance. Here, we report the synthesis and characterization of donor-linker-acceptor block copolymers for use in OPVs. A series of poly(3-hexylthiophene)-block- poly((9,9-dioctylfluorene)-2,7-diyl-alt-[4,7-bis(thiophen-5-yl)-2,1,3-benzothiadiazole]-2',2''-diyl) (P3HT-linkerPFTBT) are synthesized with flexible oligo-ethylene glycol (PEG) linkers. Photoluminescence measurements demonstrate that the insertion of a non-conjugated linker has a significant impact on energy transfer between the two blocks, and the block copolymers are used as additives for bulk heterojunction OPVs. This work provides insight into the charge separation process and demonstrates a technique for tailoring the donor-accepter interface in OPVs.

To describe the direct and indirect costs incurred by Australian living kidney donors. We studied 55 living kidney donors from 3 centres in Perth, Australia and 1 centre in Melbourne, Australia (2010-2014); 49 donors provided information on expenses incurred during the donor evaluation period and up to 3 months after donation. We used a micro-costing approach to measure and value the units of resources consumed. Expenses were grouped as direct costs (ground and air travel, accommodation, and prescription medications) and indirect costs (lost wages and lost productivity). We standardized costs to the year 2016 in Australian dollars. The most common direct costs were for ground travel (100%), parking (76%), and post-donation pain medications or antibiotics (73%). The highest direct costs were for air travel (median $1,986 [3 donors]) and ground travel (median $459 [49 donors]). Donors also reported lost wages (median $9,891 [37 donors]). The inability to perform household activities or care for dependants were reported by 32 (65%) and 23 (47%) donors. Total direct costs averaged $1,682 per donor (median $806 among 49 donors). Total indirect costs averaged $7,249 per donor (median $7,273 among 49 donors). Total direct and indirect costs averaged $8,932 per donor (median $7,963 among 49 donors). Many Australian living kidney donors incur substantial costs during the donation process. Our findings inform the continued development of policies and programs designed to minimize costs incurred by living kidney donors. This article is protected by copyright. All rights reserved.

To use optical coherence tomography (OCT) as a noninvasive tool to perform in situ characterization of eye bank corneal tissue processed for lamellar keratoplasty. A custom-built ultrahigh-resolution OCT (UHR-OCT) was used to characterize donor corneal tissue that had been processed for lamellar keratoplasty. Twenty-seven donor corneas were analyzed. Four donor corneas were used as controls, whereas the rest were processed into donor corneal buttons for lamellar transplantation by using hand dissection, a microkeratome, or a femtosecond laser. UHR-OCT was also used to noninvasively characterize and monitor the viable corneal tissue immersed in storage medium over 3 weeks. The UHR-OCT captured high-resolution images of the donor corneal tissue in situ. This noninvasive technique showed the changes in donor corneal tissue morphology with time while in storage medium. The characteristics of the lamellar corneal tissue with each processing modality were clearly visible by UHR-OCT. The in situ characterization of the femtosecond laser-cut corneal tissue was noted to have more interface debris than shown by routine histology. The effects of the femtosecond laser microcavitation bubbles on the corneal tissue were well visualized at the edges of the lamellar flap while in storage medium. The results of our feasibility study show that UHR-OCT can provide superb, in situ microstructural characterization of eye bank corneal tissue noninvasively. The UHR-OCT interface findings and corneal endothelial disc thickness uniformity analysis are valuable information that may be used to optimize the modalities and parameters for lamellar tissue processing. The UHR-OCT is a powerful approach that will allow us to further evaluate the tissue response to different processing techniques for posterior lamellar keratoplasty. It may also provide information that can be used to correlate with postoperative clinical outcomes. UHR-OCT has the potential to become a routine part of tissue analysis for any eye bank or centers creating customized lamellar corneal tissue for transplantation.

Change of focus: from intensive care towards organ donation.

Meyer, Käthe; Bjørk, Ida T

2008-02-01

To progress from identifying a potential organ donor to implementing the actual organ donation effectively is a challenging process for all involved. The nurses might find the change of focus difficult, as the donor organ acquisition process often starts before the relatives had been informed and have had the time to reorient themselves about the severe situation of the patient and have been briefed on the option of organ donation. The purpose was to investigate the hospital-based education in organ donation at the 28 Norwegian donor hospitals, and elicit the needs of the intensive care nurses for imparting of required knowledge and support in shifting their focus from intensive care towards the process of organ procurement. Hospital-based education and guidelines in organ donation were analyzed by scrutinizing the documents available. Eleven units were found to have their own guidelines and only three hospitals had organ donation in their educational programme. Intensive care nurses at three hospitals participated in focus groups. The main finding was the need for collaboration and mutual understanding within the treatment team. Nurses expounded the multiple responsibilities that they discharged during the course of intensive care. In reorienting their focus from intensive care to donor organ procurement, the time of death was explained as the crucial turning point. The knowledge of intensive care staff and professional competence were crucial in winning the relatives' trust and were central in the communication processes. Donor hospitals should implement systematic training and debriefing, where both nurses and physicians contribute to this process. Well-prepared protocols for organ donation at hospitals can define responsibilities assigned to different members of the donor organ acquisition team.

Ethical guidelines for the evaluation of living organ donors

2004-01-01

Transplantation is an effective, life-prolonging treatment for organ failure. Demand has steadily increased over the past decade, creating a shortage in the supply of organs. In addition, the number of deceased organ donors has reached a plateau. Living-donor transplantation is increasingly an option, influenced by favourable clinical outcomes and increased waiting times at most transplant centres across North America. Living-donor kidney transplants have exceeded deceased-donor transplant rates at some centres. Organ donations from living donors have challenged transplant programs to develop a framework for determining donor acceptability. After a multidisciplinary consensus-building process of discussion and debate, the Multi-Organ Transplant Program of the University Health Network in Toronto has developed ethical guidelines for these procedures. These proposed guidelines address ethical concerns related to selection criteria and procedures, voluntariness, informed consent and disclosure of risks and benefits to both donor and recipient.

Rodrigue, James R.; Cornell, Danielle L.; Howard, Richard J.

2008-01-01

We examined the instability of organ donation decisions made by next-of-kin and factors that predict whether non-donors wish they had consented to donation. Next-of-kin of donor-eligible individuals from one organ procurement organization participated in a semi-structured telephone interview. Participants were asked if they would make the same decision if they had to make it again today. Of the 147 next-of-kin donors, 138 (94%) would make the same decision again; 6 (4%) would not consent to donation, and 3 (2%) were unsure. Of the 138 next-of-kin non-donors, 89 (64%) would make the same decision again, 37 (27%) would consent to donation, and 12 (9%) were unsure. Regret among non-donors was more likely when the next-of-kin had more favorable transplant attitudes (OR=1.76, CI=1.15, 2.69), had the first donation discussion with a non-OPO professional (OR=0.21, CI=0.13, 0.65), was not told their loved one was dead before this discussion (OR=0.23, CI=0.10, 0.50), did not feel they were given enough time to make the decision (OR=0.25, CI=0.11, 0.55), had not discussed donation with family members (OR=0.30, CI=0.13, 0.72), and had not heard a public serve announcement about organ donation (OR=0.29, CI=0.13, 0.67). OPOs should consider targeting these variables in educational campaigns and donation request approaches. PMID:18853951

The Human Milk Banking Association of North America (HMBANA) is a nonprofit association that standardizes and facilitates the establishment and operation of donor human milk (DHM) banks in North America. Each HMBANA milk bank in the network collects data on the DHM it receives and distributes, but a centralized data repository does not yet exist. In 2010, the Food and Drug Administration recognized the need to collect and disseminate systematic, standardized DHM bank data and suggested that HMBANA develop a DHM data repository. This study aimed to describe data currently collected by HMBANA DHM banks and evaluate feasibility and interest in participating in a centralized data repository. We conducted phone interviews with individuals in different HMBANA milk banks and summarized descriptive statistics. Eight of 13 (61.5%) sites consented to participate. All respondents collected donor demographics, and half (50%; n = 4) rescreened donors after 6 months of continued donation. The definition of preterm milk varied between DHM banks (≤ 32 to ≤ 40 weeks). The specific computer program used to house the data also differed. Half (50%; n = 4) indicated that they would consider participation in a centralized repository. Without standardized data across all HMBANA sites, the creation of a centralized data repository is not yet feasible. Lack of standardization and transparency may deter implementation of donor milk programs in the neonatal intensive care unit setting and hinder benchmarking, research, and quality improvement initiatives.

Prior research examining rationales for enrolling as an organ donor is biased because of its reliance on college student samples and retrospective recall. To characterize New York state residents' registry enrollment decisions in close proximity to a registration opportunity. -Surveys were conducted with customers exiting Department of Motor Vehicle offices. A total of 1325 customers were surveyed upon exiting 1 of 18 Department of Motor Vehicle offices spanning 9 counties. Customers making donation-relevant transactions (ie, license renewal/registration) reported whether they had registered as a donor that day, and all other customers reported whether they had registered as a donor in the past. Customers reported reasons to justify their enrollment decision through short interview questions. Among current donation-relevant transactions (n = 299), 27% reported enrolling in the registry. Of remaining customers, 39% reported enrolling in the state registry in the past. For those who elected not to enroll, many failed to communicate a reason for their decision, or reported a lack of opportunity to sign or decisional uncertainty. Among enrollees, reasons for registration included the altruistic benefits of donation, prior registration, personal experience with donation, and rational arguments for donation. The value of point-of-decision survey data are discussed in relation to strategic efforts to promote organ donor registration.

The spin relaxation of nitrogen donors in 6H SiC crystals as studied by the electron spin echo method

We present the detailed study of the spin kinetics of the nitrogen (N) donor electrons in 6H SiC wafers grown by the Lely method and by the sublimation “sandwich method” (SSM) with a donor concentration of about 10{sup 17 }cm{sup −3} at T = 10–40 K. The donor electrons of the N donors substituting quasi-cubic “k1” and “k2” sites (N{sub k1,k2}) in both types of the samples revealed the similar temperature dependence of the spin-lattice relaxation rate (T{sub 1}{sup −1}), which was described by the direct one-phonon and two-phonon processes induced by the acoustic phonons proportional to T and to T{sup 9}, respectively. Themore » character of the temperature dependence of the T{sub 1}{sup −1} for the donor electrons of N substituting hexagonal (“h”) site (N{sub h}) in both types of 6H SiC samples indicates that the donor electrons relax through the fast-relaxing centers by means of the cross-relaxation process. The observed enhancement of the phase memory relaxation rate (T{sub m}{sup −1}) with the temperature increase for the N{sub h} donors in both types of the samples, as well as for the N{sub k1,k2} donors in Lely grown 6H SiC, was explained by the growth of the free electron concentration with the temperature increase and their exchange scattering at the N donor centers. The observed significant shortening of the phase memory relaxation time T{sub m} for the N{sub k1,k2} donors in the SSM grown sample with the temperature lowering is caused by hopping motion of the electrons between the occupied and unoccupied states of the N donors at N{sub h} and N{sub k1,k2} sites. The impact of the N donor pairs, triads, distant donor pairs formed in n-type 6H SiC wafers on the spin relaxation times was discussed.« less

A quantitative method was developed and validated to assess bioburden on tissue from human donors and to compare bioburden determination results to swab culture results from the same donor. An initial study with allograft tissue from 101 donors showed a wide range of bioburden levels; values from no colony-forming units (CFU) detected to >28,000 CFU were observed. Tissues from donors that had swab cultures negative for objectionable microorganisms generally had lower bioburden than tissues from donors where objectionable microorganisms were recovered by swab culturing. In a follow-up study with 1,445 donors, a wide range of bioburden levels was again observed on tissues from donors that were swab culture negative for objectionable microorganisms. Tissues from 885 (61%) of these donors had no recoverable bioburden (<2 CFU). Importantly, tissues from 560 (39%) of the donors had recoverable bioburden which ranged from 1 to >24,000 CFU. Identification of bioburden isolates showed a diversity of genera and species. In compliance with the recent revision of the American Association of Tissue Banks K2.210 Standard, the quantitative bioburden determination method was validated with a composite tissue sample that contains bone and soft tissue sections tested together in one extraction vessel. A recovery efficiency of 68% was validated and the composite sample was shown to be representative of all of the tissues recovered from a donor. The use of the composite sample in conjunction with the quantitative bioburden determination method will facilitate an accurate assessment of the numbers and types of contaminating microorganisms on allografts prior to disinfection/sterilization. This information will ensure that disinfection/sterilization processes are properly validated and the capability of the overall allograft process is understood on a donor by donor basis.

St. Louis encephalitis virus is a mosquito-borne flavivirus that infrequently causes epidemic central nervous system infections. In the United States, blood donors are not screened for St. Louis encephalitis virus infection, and transmission through blood transfusion has not been reported. During September 2015, St. Louis encephalitis virus infection was confirmed in an Arizona kidney transplant recipient. An investigation was initiated to determine the infection source. The patient was interviewed, and medical records were reviewed. To determine the likelihood of mosquito-borne infection, mosquito surveillance data collected at patient and blood donor residences in timeframes consistent with their possible exposure periods were reviewed. To investigate other routes of exposure, organ and blood donor and recipient specimens were obtained and tested for evidence of St. Louis encephalitis virus infection. The patient presented with symptoms of central nervous system infection. Recent St. Louis encephalitis virus infection was serologically confirmed. The organ donor and three other organ recipients showed no laboratory or clinical evidence of St. Louis encephalitis virus infection. Among four donors of blood products received by the patient via transfusion, one donor had a serologically confirmed, recent St. Louis encephalitis virus infection. Exposure to an infected mosquito was unlikely based on the patient's minimal outdoor exposure. In addition, no St. Louis encephalitis virus-infected mosquito pools were identified around the patient's residence. This investigation provides evidence of the first reported possible case of St. Louis encephalitis virus transmission through blood product transfusion. Health care providers and public health professionals should maintain heightened awareness for St. Louis encephalitis virus transmission through blood transfusion in settings where outbreaks are identified. © 2017 AABB.

Malaria parasite is usually transmitted to humans by Anopheles mosquitoes but it can also be transmitted through blood transfusion. Usually malaria transmission is low in African urban settings. In West Africa where the P. falciparum is the most predominant malaria species, there are limited measures to reduce the risk of blood transfusion malaria. The aim of this study was to evaluate the prevalence of P. falciparum malaria carriage among blood donors in the National Blood Center of Bamako, capital city of Mali. The study was conducted using a random sample of 946 blood donors in Bamako, Mali, from January to December 2011. Screening for malaria was performed by thick smear and rapid diagnostic test (RDT). Blood group was typed by Beth-Vincent and Simonin techniques. The frequency of malaria infection was 1.4% by thick smear and 0.8% by the RDT. The pick prevalence of P. falciparum malaria was in rainy season, indicating a probable high seasonal risk of malaria by blood transfusion, in Mali. The prevalence of P. falciparum infection was 2% among donors of group O the majority being in this group. There is a seasonal prevalence of malaria among blood donors in Bamako. A prevention strategy of transfusion malaria based on the combination of selection of blood donors through the medical interview, promoting a voluntary low-risk blood donation and screening all blood bags intended to be transfused to children under 5, pregnant women and immune-compromised patients during transmission season using thick smear will reduce the risk of transfusion malaria in Mali.

Design of organic ternary blends and small-molecule bulk heterojunctions: photophysical considerations

NASA Astrophysics Data System (ADS)

Rajesh, Kallarakkal Ramakrishnan; Paudel, Keshab; Johnson, Brian; Hallani, Rawad; Anthony, John; Ostroverkhova, Oksana

2015-01-01

We explored relationships between photophysical processes and solar cell characteristics in solution-processable bulk heterojunctions (BHJs), in particular: (1) polymer donor:fullerene acceptor:small-molecule (SM) nonfullerene acceptor, (2) polymer donor:SM donor:SM nonfullerene acceptor, and (3) SM donor:SM nonfullerene or fullerene acceptor. Addition of a nonfullerene SM acceptor to "efficient" polymer:fullerene BHJs led to a reduction in power conversion efficiency (PCE), mostly due to decreased charge photogeneration efficiency and increased disorder. By contrast, addition of an SM donor to "inefficient" polymer:SM nonfullerene acceptor BHJs led to a factor of two to three improvement in the PCE, due to improved charge photogeneration efficiency and transport. In most blends, exciplex formation was observed and correlated with a reduced short-circuit current (Jsc) without negatively impacting the open-circuit voltage (Voc). A factor of ˜5 higher PCE was observed in SM donor:fullerene acceptor BHJs as compared to SMBHJs with the same SM donor but nonfullerene acceptor, due to enhanced charge carrier photogeneration in the blend with fullerene. Our study revealed that the HOMO and LUMO energies of molecules comprising a blend are not reliable parameters for predicting Voc of the blend, and an understanding of the photophysics is necessary for interpreting solar cell characteristics and improving the molecular design of BHJs.

A Qualitative Study of Turning Points or Aha! Moments in Older Adults' Discussions About Organ Donation.

PubMed

Downing, Kimberly; Jones, Linda L

2018-01-01

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

Towards a standardized informed consent procedure for live donor nephrectomy: What do surgeons tell their donors?

2016-08-01

Living kidney donors comprise a unique group of "patients", undergoing an operation for the benefit of others. The informed consent process is therefore valued differently. Although this is a team effort, the surgeon is responsible for performing the donor nephrectomy, and often the one held accountable, should adverse events occur. Although there is some consensus on how the informed consent procedure should be arranged, practices vary. The aim of this study was to evaluate the surgical informed consent procedure for live donor nephrectomy, with special regards to disclosure of complications. A web-based survey was sent to all kidney transplant surgeons (n = 50) in eight transplant centers with questions regarding the local procedure and disclosure of specific details. Response rate was 98% (n = 49), of which 32 (65%) were involved in living donor education; overall, transplant- (50%), vascular- (31%), and abdominal surgeons (13%), and urologists (6%) performed donor nephrectomies in the eight centers. Informed consent procedures varied, ranging from assumed to signed consent. Bleeding was the only complication every surgeon mentioned. Risk of death was always mentioned by 16 surgeons (50%), sometimes by 13 (41%), three surgeons (9%) never disclosed this disastrous complication. Reported mortality rates ranged from 0.003% to 0.1%. Mentioning frequencies for all other complications varied. Important complications are not always disclosed during the surgical informed consent process for live donor nephrectomy. Informed consent procedures vary. To optimally prepare living kidney donors for the procedure, a standardized informed consent procedure for live donor nephrectomy is highly recommended.

Donor-bridge-acceptor energetics determine the distance dependence of electron tunneling in DNA

NASA Astrophysics Data System (ADS)

Lewis, Frederick D.; Liu, Jianqin; Weigel, Wilfried; Rettig, Wolfgang; Kurnikov, Igor V.; Beratan, David N.

2002-10-01

Electron transfer (ET) processes in DNA are of current interest because of their involvement in oxidative strand cleavage reactions and their relevance to the development of molecular electronics. Two mechanisms have been identified for ET in DNA, a single-step tunneling process and a multistep charge-hopping process. The dynamics of tunneling reactions depend on both the distance between the electron donor and acceptor and the nature of the molecular bridge separating the donor and acceptor. In the case of protein and alkane bridges, the distance dependence is not strongly dependent on the properties of the donor and acceptor. In contrast, we show here that the distance decay of DNA ET rates varies markedly with the energetics of the donor and acceptor relative to the bridge. Specifically, we find that an increase in the energy of the bridge states by 0.25 eV (1 eV = 1.602 × 1019 J) relative to the donor and acceptor energies for photochemical oxidation of nucleotides, without changing the reaction free energy, results in an increase in the characteristic exponential distance decay constant for the ET rates from 0.71 to 1.1 Å1. These results show that, in the small tunneling energy gap regime of DNA ET, the distance dependence is not universal; it varies strongly with the tunneling energy gap. These DNA ET reactions fill a "missing link" or transition regime between the large barrier (rapidly decaying) tunneling regime and the (slowly decaying) hopping regime in the general theory of bridge-mediated ET processes.

The process of ageing has an impact on the entire human body including the organ systems. In transplantation, professionals are daily faced with risk assessment of suitable donor offers , whether to accept a liver graft for a specific recipient. In this context, livers from elderly donors are more frequently accepted for transplantation, to increase the donor pool and compensate the high waiting list mortality. In the current practice it is not unusual to accept 60-year old donor livers for transplantation, as the donor demographics have significantly changed over the years. However, controversy exists regarding the use of livers from donors above 70 or 80 years, particular in combination with other risk factors, e.g. liver steatosis, warm ischaemia or long cold storage. This review focuses first on the impact of ageing on liver morphology and function. Second, we will highlight outcome after transplantation from elderly donors. Finally, we describe further risk factors and donor-recipient selection under the scope of old donor organs and include our institutional experience and policy. Copyright © 2017 Elsevier Ltd.

Return of results in translational iPS cell research: considerations for donor informed consent

PubMed Central

2013-01-01

Efforts have emerged internationally to recruit donors with specific disease indications and to derive induced pluripotent cell lines. These disease-specific induced pluripotent stem cell lines have the potential to accelerate translational goals such as drug discovery and testing. One consideration for donor recruitment and informed consent is the possibility that research will result in findings that are clinically relevant to the cell donor. Management protocols for such findings should be developed a priori and disclosed during the informed consent process. The California Institute for Regenerative Medicine has developed recommendations for informing donors in sponsored research. These recommendations include obtaining consent to recontact tissue donors for a range of scientific, medical and ethical considerations. This article reviews the basis for these recommendations and suggests conditions that may be appropriate when reporting findings to donors. PMID:23336317

We demonstrated the performance of unconventional, all-fullerene-based, planar heterojunction (PHJ) organic photovoltaic (OPV) cells using fullerene derivatives indene-C{sub 60} bisadduct (ICBA) and phenyl C{sub 61}-butyric acid methyl ester as the electron donors with fullerene C{sub 70} as the electron acceptor. Two different charge generation processes, including charge generation in the fullerene bulk and exciton dissociation at the donor-acceptor interface, have been found to exist in such all-fullerene-based PHJ cells and the contribution to the total photocurrent from each process is strongly dependent on the thickness of fullerene donor. The optimized 5 nm ICBA/40 nm C{sub 70} PHJ cell gives clear external quantummore » efficiency responses for the long-wavelength photons corresponding to the dissociation of strongly bound Frenkel excitons, which is hardly observed in fullerene-based single layer reference devices. This approach using fullerene as a donor material provides further possibilities for developing high performance OPV cells.« less

We performed a multicenter study in 1989 to determine whether screening whole-blood donors for human immunodeficiency virus type 1 (HIV-1) p24 antigen would improve transfusion safety by identifying carriers of the virus who are seronegative for HIV-1 antibody. More than 500,000 donations were tested at 13 U.S. blood centers with test kits from two manufacturers. Units found repeatedly reactive were retested in a central laboratory; if the results were positive, they were confirmed by a neutralization assay. A subgroup of units was also tested for HIV-1 by the polymerase chain reaction. Selected donors confirmed or not confirmed as having p24 antigen were contacted for follow-up interviews to identify risk factors and undergo retesting for HIV-1 markers. Positive tests for p24 antigen were confirmed by neutralization in five donors (0.001 percent of all donations tested), all of whom were also positive for HIV-1 antibody and HIV-1 by polymerase chain reaction. Three of the antigen-positive donors had other markers of infectious disease that would have resulted in the exclusion of their blood; two had risk factors for HIV-1 that should have led to self-exclusion. Of 220 blood units with repeatedly reactive p24 antigen whose presence could not be confirmed by neutralization (0.04 percent of the donations studied), none were positive for HIV-1 antibody, HIV-1 by polymerase chain reaction (120 units tested), or virus culture (76 units tested)--attesting to the specificity of confirmatory neutralization. The finding that no donation studied was positive for p24 antigen and negative for HIV-1 antibody suggests that screening donors for p24 antigen with tests of the current level of sensitivity would not add substantially to the safety of the U.S. blood supply.

Rhodes, Beverly; Anderlini, Paolo

2015-01-01

The rapid growth of the use of recombinant human granulocyte colony-stimulating factor (rhG-CSF) to mobilize and collect allogeneic peripheral blood stem cells (PBSCs) for transplantation has made it a new international standard. While the procedure remains safe, older donors, donors with significant comorbidities and pediatric donors are now often employed. This brings a new set of challenges in the donor evaluation, medical clearance, informed consent and collection process. Rare and unexpected severe adverse events related to rhG-CSF administration and PBSC apheresis have been described. Proper PBSC donor counseling, evaluation and care have become even more important.

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

PubMed

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.

Informed consent is mandatory for all (surgical) procedures, but it is even more important when it comes to living kidney donors undergoing surgery for the benefit of others. Donor education, leading to informed consent, needs to be carried out according to certain standards. Informed consent procedures for live donor nephrectomy vary per centre, and even per individual healthcare professional. The basis for a standardised, uniform surgical informed consent procedure for live donor nephrectomy can be created by assessing what information donors need to hear to prepare them for the operation and convalescence. The PRINCE (Process of Informed Consent Evaluation) project is a prospective, multicentre cohort study, to be carried out in all eight Dutch kidney transplant centres. Donor knowledge of the procedure and postoperative course will be evaluated by means of pop quizzes. A baseline cohort (prior to receiving any information from a member of the transplant team in one of the transplant centres) will be compared with a control group, the members of which receive the pop quiz on the day of admission for donor nephrectomy. Donor satisfaction will be evaluated for all donors who completed the admission pop-quiz. The primary end point is donor knowledge. In addition, those elements that have to be included in the standardised format informed consent procedure will be identified. Secondary end points are donor satisfaction, current informed consent practices in the different centres (eg, how many visits, which personnel, what kind of information is disclosed, in which format, etc) and correlation of donor knowledge with surgeons' estimation thereof. Approval for this study was obtained from the medical ethical committee of the Erasmus MC, University Medical Center, Rotterdam, on 18 February 2015.

Secrecy, disclosure and everything in-between: decisions of parents of children conceived by donor insemination, egg donation and surrogacy

2011-01-01

This study examined families where children lack a genetic and/or gestational link with their parents. A total of 101 families (36 donor insemination families, 32 egg donation families and 33 surrogacy families) were interviewed when the child was aged 7 years. Despite a shift in professional attitudes towards openness, about half of the children conceived by egg donation and nearly three-quarters of those conceived by donor insemination remained unaware that the person they know as their mother or father is not, in fact, their genetic parent. By contrast, almost all the surrogacy parents had told their child how they were born. A majority of parents who planned never to tell their child about their conception had told at least one other person. However, qualitative data indicated that to categorize families as ‘secret’ or ‘open’ is inadequate. In fact many parents engage in ‘layers’ of disclosure about their child’s conception, both with their child and with family and friends. PMID:21398181

Findings are presented of the third phase of a longitudinal study of children conceived by assisted reproduction procedures involving surrogacy and/or donor conception. At the time of the child's third birthday, 34 surrogacy families, 41 donor insemination families and 41 oocyte donation families were compared with 67 natural conception families on standardized interview and questionnaire measures of the psychological well-being of the parents, mother-child relationships and the psychological well-being of the child. The differences found between family types reflected higher levels of warmth and interaction between mothers and their 3-year-old children in assisted reproduction families than in families with a naturally conceived child. A higher proportion of surrogacy parents than donor conception parents had told their children about the nature of their birth. It appears that the absence of a genetic and/or gestational link between parents and their child does not have a negative impact on parent-child relationships or the psychological well-being of mothers, fathers or children at age 3.

Advanced Donation Programs and Deceased Donor-Initiated Chains-2 Innovations in Kidney Paired Donation.

PubMed

Wall, Anji E; Veale, Jeffrey L; Melcher, Marc L

2017-12-01

Kidney paired donation (KPD) strategies have facilitated compatible living-donor kidney transplants for end-stage renal disease patients with willing but incompatible living donors. Success has inspired further innovations that expand opportunities for kidney-paired donation. Two such innovations are the advanced donation strategy in which a donor provides a kidney before their recipient is matched, or even in need of, a kidney transplant, and deceased donor initiated chains in which chains are started with deceased donors rather than altruistic living donors. Although these innovations may expand KPD, they raise several ethical issues. Specific concerns raised by advanced donation include the management of uncertainty, the extent of donor and recipient consent, the scope of the obligation that the organization has to the kidney exchange paired recipient, the naming of alternative recipients, and the potential to unfairly advantage the recipient. Use of deceased donors for chain-initiating kidneys raises ethical issues concerning the consent process for each involved party, the prioritization of deceased donor kidneys, the allocation of chain ending kidneys, and the value of a living donor kidney versus a deceased donor kidney. We outline each ethical issue and discuss how it can be conceptualized and managed so that these KPD innovations programs are ultimately successful.

A second allogeneic hematopoietic stem-cell transplantation and donor lymphocyte infusion using cells from the same donor is a therapeutic option in the case of stem-cell graft failure or disease relapse, but little is known about the factors associated with the CD34 + cell yields from second donations. One-hundred healthy donors who underwent a second mobilization treatment and peripheral blood stem-cell (PBSC) collection were studied. For both mobilization processes, 5 µg of granulocyte colony-stimulating factor per kg per day was administered. The blood counts of the donors were monitored during the processes. The second donations from the same donors provided lower apheresis yields than did the initial collections. The number of CD34 + cells collected from normal donors after a second cycle of PBSC mobilization was associated with their steady-state lymphocyte counts and the intertransplantation interval. Female sex negatively affected the CD34 + cell yields. The cutoff value for the steady-state absolute lymphocyte count was 2.055 × 10 9 /L. To harvest greater numbers of CD34 + cells from second collections, male donors and those with intervals of longer than 9 months between donations should be selected. The lymphocyte counts prior to the first donations may predict the content of CD34 + cells in the allografts prepared using the second donations. Copyright © 2016 Elsevier Ltd. All rights reserved.

The ethics of donor human milk banking.

PubMed

Arnold, Lois D W

2006-01-01

This case study of donor human milk banking and the ethics that govern interested parties is the first time the ethics of donor milk banking has been explored. Two different models of ethics and their direct impact on donor milk banking are examined: biomedical ethics and public health ethics. How these models and principles affect different aspects of donor human milk banking and the parties involved in the delivery of this service are elucidated. Interactions of parties with each other and how the quality and type of interaction affects the ethical delivery of donor milk banking services are described. Crystallization is at the heart of the qualitative methodology used. Writing as a method of inquiry, an integrative research review, and personal experience are the three methods involved in the crystallization process. Suggestions are made for improving access and knowledge of banked donor human milk, a valuable public health resource.

[Donors' personal profile in Tuscany's network of milk banks].

2012-10-01

An investigation on human milk donors among the milk banks of Tuscany's network was carried out. Milk banks select, collect, check, process, store and deliver human milk, whose donors should have certain physical and psychological well-being features. The aim of the study was to describe a personal and social profile of milk donors. The study included a sample of 100 milk donors and a sample of 100 non-milk donor mothers; a questionnaire that collected data about mothers' general information, clinical history, pregnancy and delivery, weight variations, state of health, lifestyle, breastfeeding and knowledge about milk banks was administered to all of them. Then information about food history of mothers has also been collected. First the samples of donors were analysed for all variables considered. Subsequently the samples of donors were compared with the samples of non-donors: statistical analysis was carried out with χ2 test and documented significant differences between donors and non-donors for the majority of variables considered in the questionnaire and for food history. Milk donors have a good state of health, and the integration in milk donation initiative headed towards a healthier lifestyle. It is necessary to promote an advertising campaign to integrate social and sanitary politics, fitting to local socio-economical contest. Furthermore, the improvement of milk banks of public hospitals is necessary, as hospitals are places of major stream both of potential donors and newborns.

The doctor-patient relationship in living donor kidney transplantation.

PubMed

Danovitch, Gabriel M

2007-11-01

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

Potential use and perspectives of nitric oxide donors in agriculture.

PubMed

Marvasi, Massimiliano

2017-03-01

Nitric oxide (NO) has emerged in the last 30 years as a key molecule involved in many physiological processes in plants, animals and bacteria. Current research has shown that NO can be delivered via donor molecules. In such cases, the NO release rate is dependent on the chemical structure of the donor itself and on the chemical environment. Despite NO's powerful signaling effect in plants and animals, the application of NO donors in agriculture is currently not implemented and research remains mainly at the experimental level. Technological development in the field of NO donors is rapidly expanding in scope to include controlling seed germination, plant development, ripening and increasing shelf-life of produce. Potential applications in animal production have also been identified. This concise review focuses on the use of donors that have shown potential biotechnological applications in agriculture. Insights are provided into (i) the role of donors in plant production, (ii) the potential use of donors in animal production and (iii) future approaches to explore the use and applications of donors for the benefit of agriculture. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

Requirements for blood and blood components intended for transfusion or for further manufacturing use. Final rule.

PubMed

2015-05-22

The Food and Drug Administration (FDA) is amending the regulations applicable to blood and blood components, including Source Plasma, to make the donor eligibility and testing requirements more consistent with current practices in the blood industry, to more closely align the regulations with current FDA recommendations, and to provide flexibility to accommodate advancing technology. In order to better assure the safety of the nation's blood supply and to help protect donor health, FDA is revising the requirements for blood establishments to test donors for infectious disease, and to determine that donors are eligible to donate and that donations are suitable for transfusion or further manufacture. FDA is also requiring establishments to evaluate donors for factors that may adversely affect the safety, purity, and potency of blood and blood components or the health of a donor during the donation process. Accordingly, these regulations establish requirements for donor education, donor history, and donor testing. These regulations also implement a flexible framework to help both FDA and industry to more effectively respond to new or emerging infectious agents that may affect blood product safety.

Vertical funding, non-governmental organizations, and health system strengthening: perspectives of public sector health workers in Mozambique

PubMed Central

2013-01-01

Background In the rapid scale-up of human immunodeficiency virus (HIV) care and acquired immunodeficiency syndrome (AIDS) treatment, many donors have chosen to channel their funds to non-governmental organizations and other private partners rather than public sector systems. This approach has reinforced a private sector, vertical approach to addressing the HIV epidemic. As progress on stemming the epidemic has stalled in some areas, there is a growing recognition that overall health system strengthening, including health workforce development, will be essential to meet AIDS treatment goals. Mozambique has experienced an especially dramatic increase in disease-specific support over the last eight years. We explored the perspectives and experiences of key Mozambican public sector health managers who coordinate, implement, and manage the myriad donor-driven projects and agencies. Methods Over a four-month period, we conducted 41 individual qualitative interviews with key Ministry workers at three levels in the Mozambique national health system, using open-ended semi-structured interview guides. We also reviewed planning documents. Results All respondents emphasized the value and importance of international aid and vertical funding to the health sector and each highlighted program successes that were made possible by recent increased aid flows. However, three serious concerns emerged: 1) difficulties coordinating external resources and challenges to local control over the use of resources channeled to international private organizations; 2) inequalities created within the health system produced by vertical funds channeled to specific services while other sectors remain under-resourced; and 3) the exodus of health workers from the public sector health system provoked by large disparities in salaries and work. Conclusions The Ministry of Health attempted to coordinate aid by implementing a “sector-wide approach” to bring the partners together in setting priorities, harmonizing planning, and coordinating support. Only 14% of overall health sector funding was channeled through this coordinating process by 2008, however. The vertical approach starved the Ministry of support for its administrative functions. The exodus of health workers from the public sector to international and private organizations emerged as the issue of greatest concern to the managers and health workers interviewed. Few studies have addressed the growing phenomenon of “internal brain drain” in Africa which proved to be of greater concern to Mozambique’s health managers. PMID:23768178

The low efficiency of somatic cell cloning is the major obstacle to widespread use of this technology. Incomplete nuclear reprogramming following the transfer of donor nuclei into recipient oocytes has been implicated as a primary reason for the low efficiency of the cloning procedure. The mechanisms and factors that affect the progression of the nuclear reprogramming process have not been completely elucidated, but the identification of these factors and their subsequent manipulation would increase cloning efficiency. At present, many groups are studying donor nucleus reprogramming. Here, we present an approach in which the efficiency of producing viable offspring is improved by selecting recipient oocytes and donor cells that will produce cloned embryos with functionally reprogrammed nuclei. This approach will produce information useful in future studies aimed at further deciphering the nuclear reprogramming process.

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5–6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.

To determine Australian emergency department clinicians' cultural and religious barriers to organ and tissue donation (OTD). A national cross-sectional survey of physicians and nurses working in Australian emergency departments. An online questionnaire of 133 items was delivered via e-mail. Responses were received from 599 of 2969 (20%) physicians and 212 of 1026 (21%) nurses. Respondents were generally representative of the colleges. Participants were from 26 cultures and 9 religious groups. Self-rated competence in OTD tasks was low for some minority groups: South American, Caribbean, and Pacific Islanders reported little competence in identifying, referring, and caring for potential donors, introducing OTD to families, and approaching distressed families. Those of Arabic, Jewish, North African, and Middle Eastern background reported low competence in referring and caring for potential donors and comforting distressed families. They reported low support for OTD after cardiac death, low familiarity with OTD processes after cardiac death, and poor familiarity with the coroner's process. Those of Southern Asian background reported low comfort in undertaking OTD processes, poor familiarity with the coroner's process, and low competence in caring for potential donors. Those of Islamic faith reported low competence in identifying potential donors, low support for OTD after cardiac death, and thought that the emergency department was an inappropriate location to identify potential donors. Those of Buddhist and Hindu faiths reported low competence in identifying potential donors. Respondent numbers for members of minority groups were low, thereby limiting the statistical accuracy of results. Among clinicians working in Australian emergency departments, religion and culture may be barriers to facilitating OTD in emergency departments because of the perceptions and attitudes held by particular religious and cultural groups. Improving access to education may address these differences.

Findings are presented on a study of 40 gay father families created through surrogacy and a comparison group of 55 lesbian mother families created through donor insemination with a child aged 3-9 years. Standardized interview, observational and questionnaire measures of stigmatization, quality of parent-child relationships, and children's adjustment were administered to parents, children, and teachers. Children in both family types showed high levels of adjustment with lower levels of children's internalizing problems reported by gay fathers. Irrespective of family type, children whose parents perceived greater stigmatization and children who experienced higher levels of negative parenting showed higher levels of parent-reported externalizing problems. The findings contribute to theoretical understanding of the role of family structure and family processes in child adjustment. © 2017 The Authors.

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

Development of an Unrelated Donor Selection Score Predictive of Survival after HCT: Donor Age Matters Most.

Donor factors, in addition to HLA matching status, have been associated with recipient survival in unrelated donor (URD) hematopoietic cell transplantation (HCT); however, there is no hierarchical algorithm that weights the characteristics of individual donors against each other in a quantitative manner to facilitate donor selection. The goal of this study was to develop and validate a donor selection score that prioritizes donor characteristics associated with better survival in 8/8 HLA-matched URDs. Two separate patient/donor cohorts, the first receiving HCT between 1999 and 2011 (n = 5952, c1), and the second between 2012 and 2014 (n = 4510, c2) were included in the analysis. Both cohorts were randomly spilt, 2:1, into training and testing sets. Despite studying over 10,000 URD transplants, we were unable to validate a donor selection score. The only donor characteristic associated with better survival was younger age, with 2-year survival being 3% better when a donor 10 years younger is selected. These results support previous studies suggesting prioritization of a younger 8/8 HLA-matched donor. This large dataset also shows that none of the other donor clinical factors tested were reproducibly associated with survival, and hence flexibility in selecting URDs based on other characteristics is justified. These data support a simplified URD selection process and have significant implications for URD registries. Copyright © 2018 The American Society for Blood and Marrow Transplantation.

Background Voluntary blood donation rates are low in sub-Saharan Africa. Sociobehavioral factors such as a belief that donated blood would be used for performing rituals deter people from donating blood. There is a need for culturally appropriate communication interventions to encourage individuals to donate blood. Health care interventions that use mobile phones have increased in developing countries, although many of them focus on SMS text messaging (short message service, SMS). A unique feature of mobile phones that has so far not been used for aiding blood donation is caller tunes. Caller tunes replace the ringing sound heard by a caller to a mobile phone before the called party answers the call. In African countries such as Ghana, instead of the typical ringing sound, a caller may hear a message or song. Despite the popularity of such caller tunes, there is a lack of empirical studies on their potential use for promoting blood donation. Objective The aim of this study was to use the technology acceptance model to explore the influence of the factors—perceived ease of use, perceived usefulness, attitude, and free of cost—on intentions of blood or nonblood donors to download blood donation-themed caller tunes to promote blood donation, if available. Methods A total of 478 blood donors and 477 nonblood donors were purposively sampled for an interviewer-administered questionnaire survey at blood donation sites in Accra, Ghana. Data were analyzed using descriptive statistics, exploratory factor analysis, and confirmatory factory analysis or structural equation modeling, leading to hypothesis testing to examine factors that determine intention to use caller tunes for blood donation among blood or nonblood donors who use or do not use mobile phone caller tunes. Results Perceived usefulness had a significant effect on intention to use caller tunes among blood donors with caller tunes (beta=.293, P<.001), blood donors without caller tunes (beta=.165, P=.02, nonblood donors with caller tunes (beta=.278, P<.001), and nonblood donors without caller tunes (beta=.164, P=.01). Attitudes had significant effect on intention to use caller tunes among blood donors without caller tunes (beta=.351, P<.001), nonblood donors with caller tunes (beta=.384, P<.001), nonblood donors without caller tunes (beta=.539, P<.001) but not among blood donors with caller tunes (beta=.056, P=.44). The effect of free-of-cost caller tunes on the intention to use for blood donation was statistically significant (beta=.169, P<.001) only in the case of nonblood donors without caller tunes, whereas this path was statistically not significant in other models. Conclusions Our results provide empirical evidence for designing caller tunes to promote blood donation in Ghana. The study found that making caller tunes free is particularly relevant for nonblood donors with no caller tunes. PMID:29728343

The purpose of this study was to compare hamstring donor-site injection versus intra-articular injection of a local anaesthetic for analgesia after anterior cruciate ligament (ACL) reconstruction. The two methods provide similar pain relief. 158 consecutive patients undergoing ACL hamstring tendon graft reconstruction (semi-tendinosus/gracilis [STG] or four-stranded semi-tendinosus [ST4]) during two periods in 2015 were included. Peripheral nerve block was not performed. At the end of surgery, 20mL of ropivacaine 7.5mg/mL was injected, intra-articularly during the early period (n=79) and into the hamstring donor site during the second period (n=79). Post-operative pain was evaluated subjectively by the patients using a visual analogue scale (VAS). We recorded patient demographics, concomitant surgical procedures, VAS pain scores, rescue analgesic use, time to discharge, and patient satisfaction. VAS pain score, side effects, and patient satisfaction were also recorded during a phone interview on the day after surgery (D1). Mean VAS pain scores were not significantly different between the two groups immediately after surgery (D0) or on D1 (D0: intra-articular, 2.08 and donor site, 1.88; Mann-Whitney P=0.6). Neither were the groups significantly different for rescue analgesic use, patient satisfaction, or quadriceps activation. The same local anaesthetic provides similar pain relief when injected intra-articularly or into the hamstring donor site after hamstring tendon ACL reconstruction (STG or ST4).

The shortage of donors for organ transplantation has stimulated debate on financial incentives for living kidney donors. This study aims to describe the range of attitudes and opinions of transplant physicians on financial reimbursement, compensation, and incentives in living kidney donation. Qualitative study. 110 transplant nephrologists and surgeons from 12 countries across 43 transplantation units in Europe, Australasia, and North America. Face-to-face semistructured interviews were conducted. Transcripts were thematically analyzed. We identified 7 major themes. Prioritizing the removal of disincentives for living kidney donors was largely deemed acceptable. By contrast, provision of financial incentives raised concerns about undermining benevolence, compromising human dignity and value, and traversing market forces. Some contended that financial incentives potentially were legitimate if regulated, arguing that this would maximize utility in transplantation, but most also acknowledged the difficulty and that operational feasibility of a regulated system of financial incentivization may be limited. Participants were English speaking and from Western high-income countries; therefore, the transferability of our findings may be limited. Transplantation specialists believed that minimizing disincentives would support equity and justice in living kidney donation. Direct financial incentivization for living kidney donors, even in the context of a regulated market, was regarded by most as unjustified because of the potential moral consequences and uncertain feasibility. Removing financial disincentives and safeguarding the intrinsic volunteerism, value, and meaning of donation were viewed to uphold integrity in living kidney donation.

Facilitation of blood donation amongst haemochromatosis patients.

PubMed

Marrow, B; Clarkson, J; Chapman, C E; Masson, S

2015-08-01

The standard medical therapy for haemochromatosis is iron removal by regular phlebotomy. Current guidelines suggest that this blood should be made available through national blood services. Here, we describe a pilot facilitating the process of blood donation amongst uncomplicated haemochromatosis patients. At a dedicated clinic, patients with uncomplicated haemochromatosis interested in becoming blood donors were offered an information leaflet and self-referral application. Upon receipt, members of the local Blood Service contacted them to confirm eligibility to donate. Data on demographics and clinical characteristics, including HFE (high Fe) genotype, co-morbidities, alcohol consumption and body mass index, were collected. Since establishing the clinic, 140 patients have attended (93 male) with median age 57. Most (n = 125; 89%) had uncomplicated haemochromatosis. Of these, 55 were potentially eligible blood donors. Amongst those eligible, there are now 29 regular blood donors, including 23 new. There is an interest and willingness to donate blood through the Blood Service amongst uncomplicated haemochromatosis patients undergoing therapeutic phlebotomy. Since the introduction of this facilitation process, we have significantly increased the number of regular donors amongst this cohort. If this process was to be replicated more widely across the UK, this could have a significant impact on the blood donor pool. © 2015 British Blood Transfusion Society.

Two solution-processable small organic molecules, (E)-6,6'-bis(4-(diphenylamino)phenyl)-1,1'-bis(2-ethylhexyl)-(3,3'-biindolinylidene)-2,2'-dione (coded as S10) and (E)-6,6'-di(9H-carbazol-9-yl)-1,1'-bis(2-ethylhexyl)-(3,3'-biindolinylidene)-2,2'-dione (coded as S11) were successfully designed, synthesized and fully characterized. S10 and S11 are based on a donor-acceptor-donor structural motif and contain a common electron accepting moiety, isoindigo, along with different electron donating functionalities, triphenylamine and carbazole, respectively. Ultraviolet-visible absorption spectra revealed that the use of triphenylamine donor functionality resulted in an enhanced intramolecular charge transfer transition and reduction of optical band gap, when compared with its carbazole analogue. Both of these materials were designed to be donor semiconducting components, exerted excellent solubility in common organic solvents, showed excellent thermal stability, and their promising optoelectronic properties encouraged us to scrutinize charge-carrier mobilities using solution-processable organic field effect transistors. Hole mobilities of the order of 2.2 × 10(-4) cm²/Vs and 7.8 × 10(-3) cm²/Vs were measured using S10 and S11 as active materials, respectively.

A clear appreciation of benefits and risks associated with living donor hepatectomy is important to facilitate counselling for the donor, family, and recipient in preparation for living donor liver transplant (LDLT). We report a life-threatening complication occurring in one of our live liver donors at 12 weeks following hemi-liver donation. We experienced five donor complications among our first 50 LDLT: Clavien Grade 1, n=1; Clavien grade 2, n=3; and Clavien grade 3B, n=1. The one with Clavien grade 3B had a life-threatening diaphragmatic hernia occurring 12 weeks following hepatectomy. This was promptly recognized and emergency surgery was performed. The donor is well at 1-year follow-up. Here we provide a review of reported instances of diaphragmatic hernia following donor hepatectomy with an attempt to elucidate the pathophysiology behind such occurrence. Life-threatening donor risk needs to be balanced with recipient benefit and risk on a tripartite basis during the counselling process for LDLT. With increasing use of LDLT, we need to be aware of such life-threatening complication. Preventive measures in this regard and counselling for such complication should be incorporated into routine work-up for potential live liver donor.

Italian gay fathers' experiences of transnational surrogacy and their relationship with the surrogate pre- and post-birth.

PubMed

Carone, Nicola; Baiocco, Roberto; Lingiardi, Vittorio

2017-02-01

This study aims to explore the experience of transnational surrogacy and the relationship with the surrogate pre- and post-birth in Italian gay father families. Couple and individual semi-structured interviews were carried out with 30 Italian gay partnered fathers with at least one child born through gestational surrogacy in California or Canada. No couples had known their surrogates or egg donors previously. The Interpretative Phenomenological Analysis indicated that three interrelated themes could be helpful for understanding the gay fathers' experience of their geographical distance from the surrogate: the perceived loss of control over the pregnancy; the surrogate as a person who facilitates the fathers' feelings of being emotionally connected to their developing child; the surrogate as an 'aunty' who, along with her family, maintains a relationship with the fathers. None of the fathers mentioned the egg donor during the interview. The study inspires reflections in offshore fertility practitioners on how pre- and ongoing surrogacy counselling for prospective gay fathers should be tailored. It further calls for the necessity of offering psychological counselling in gay fathers' resident countries in order to promote informed decisions before starting surrogacy abroad and to elaborate on potential difficulties related to surrogacy after the child's birth.

Little information exists on the effect of race and ethnicity on collection of peripheral blood stem cells (PBSC) for allogeneic transplantation. We studied 10776 donors from the National Marrow Donor Program who underwent PBSC collection from 2006-2012. Self-reported donor race/ethnic information included Caucasian, Hispanic, Black/African American (AA), Asian/Pacific Islander (API), and Native American (NA). All donors were mobilized with subcutaneous filgrastim (G-CSF) at an approximate dose of 10 µg/kg/d for 5 days. Overall, AA donors had the highest median yields of mononuclear cells (MNC)/L and CD34+ cells/L blood processed (3.1 × 109 and 44 × 106 respectively) while Caucasians had the lowest median yields at 2.8 × 109 and 33.7 × 106 respectively. Multivariate analysis of CD34+/L mobilization yields using Caucasians as the comparator and controlling for age, gender, body mass index, and year of apheresis revealed increased yields in overweight and obese AA and API donors. In Hispanic donors, only male obese donors had higher CD34+/L mobilization yields compared to Caucasian donors. No differences in CD34+/L yields were seen between Caucasian and NA donors. Characterization of these differences may allow optimization of mobilization regimens to allow enhancement of mobilization yields without compromising donor safety. PMID:25316111

Background and Objectives. This study was conducted to assess the level of intention of the general public towards blood donation and the factors associated with it. Methods. A descriptive cross-sectional study was conducted in South-East Botswana amongst participants aged 21–65 years. An interviewer-administered questionnaire was completed for 384 participants. Results. Of the 384 participants, 104 (27.1%) reported that they had donated blood in the past and 269 (70.1%) stated that they were willing to donate blood in the future. Thirteen out of the 104 past donors (12.5%) reported that they had donated blood in the 12 months preceding the survey and only 10 (9.6%) participants reported that they have been regular donors. In the backward logistic regression analysis, the variables that remained significant predictors of the intention to donate blood were secondary education (adjusted odds ratio (AOR) (95% confidence interval (CI)): 2.92 (1.48, 5.77)), tertiary education (AOR (95% CI): 3.83 (1.52, 9.62)), and knowing a family member who had ever donated blood (AOR (95% CI): 2.84 (1.58, 5.12)). Conclusion. Being informed about blood transfusion and its life-saving benefits through either the education system or the experience made people more likely to intend to donate blood. Evidence-based interventions to retain blood donors as regular donors are recommended. PMID:25431742

Park, I. S.; Haller, E. E.

1988-01-01

Using high-resolution far-infrared Fourier transform absorption spectroscopy and Hall effect measurements, the evolution of the shallow acceptor and donor impurity levels in germanium during and after the neutron transmutation doping process was studied. The results show unambiguously that the gallium acceptor level concentration equals the concentration of transmutated Ge-70 atoms during the whole process indicating that neither recoil during transmutation nor gallium-defect complex formation play significant roles. The arsenic donor levels appear at full concentration only after annealing for 1 h at 450 C. It is shown that this is due to donor-radiation-defect complex formation. Again, recoil does not play a significant role.

Identification of strategies to improve organ donor use remains imperative. Despite the association between hospital volume and outcomes for many common disease processes, there have been no studies that assess the impact of organ donor hospital volume on organ yield. A prospective observational study of all deceased organ donors managed by 10 organ procurement organizations across United Network for Organ Sharing regions 4, 5, and 6 was conducted from February 2012 to June 2015. To study the impact of hospital volume on organ yield, each donor was placed into a hospital-volume quartile based on the number of donors managed by their hospital. Stepwise logistic regression was used to identify the independent effect of hospital volume on the primary outcomes measure of having ≥4 organs transplanted per donor. Data from 4,427 donors across 384 hospitals were collected and hospitals were assigned quartiles based on their volume of deceased donors. Hospitals managed a mean ± SD of 3.3 ± 5.2 donors per hospital per year. After adjusting for age, ethnicity, donor type, blood type, BMI, creatinine, and organ procurement organization/donor service area, being managed in hospitals within the highest volume quartile remained a positive independent predictor of ≥4 organs transplanted per donor (odds ratio = 1.52; 95% CI 1.29 to 1.79; p < 0.001). Deceased organ donor hospital volume impacts organ yield, with the highest-volume centers being 52% more likely to achieve ≥4 organs transplanted per donor. Efforts should be made to share practices from these higher-volume centers and consideration should be given to centralization of donor care. Published by Elsevier Inc.

Despite the many important uses for human cadavers, there is a relative shortage of bodies donated to the scientific community in the United States of America. The purpose of this study was to determine the community's perceptions regarding whole body donation and their willingness to become donors. Moreover, we aimed to investigate people's understanding of the process of whole body donation, and examine their opinions regarding its importance. Individuals in Erie, Pennsylvania were surveyed. Data were collected via a questionnaire, which was offered to friends and family members of patients in the waiting area of the UPMC Hamot Surgery Center. All participants were residents of Erie County. The questionnaire was designed to evaluate knowledge and opinions about whole body donation. A total of 123 people completed the survey. We found people were willing to become whole body donors and understood the importance of this giving act, but lacked understanding about the registration process and the use of donated bodies. Participants revealed the belief that they have the right to decide what is to be done with their bodies after death, but did not indicate specific negative repercussions of becoming whole body donors. In conclusion, our findings indicate that the shortage of cadaveric donors could be due to lack of understanding about whole body donation and the registration process. © 2015 Wiley Periodicals, Inc.

The aim of the study was to test the relative efficacy of action planning and reward distribution to promote retention of whole blood donors. A sample of 7,399 donors was randomised to one of three interventions: "action planning" (n=2,585); "reward" (n=2,397); and "thank you" (n=2,417). Participants in the action planning condition were invited to write the date of their next donation on a post-it note before taking it home at the end of the donation process. Participants in the "reward" condition were given an anti-theft credit card sleeve at the end of the donation process. The "thank you" intervention is the usual condition at the end of the process; it was considered the control condition. The dependent variable was the proportion of donors who registered to give blood at six months. Overall, 4,444 (60.06%) donors registered to give blood at six months. There were no differences between the three interventions in the proportions of donors who registered to give blood (d.f. 2, chi-square=3.72, p<0.15). However, gender modified the effect of the intervention (d.f. 2, chi-square=6.57, p<0.0375); more women registered in the "thank you" condition than in the other two. The results suggest that action planning and the distribution of a reward have no motivational effect on the return to give blood. Nonetheless, women appear to respond more negatively to these interventions at the end of the donation process.

Donor vigilance is an important part of the quality management system of blood transfusion services. The evaluation of donor side effects helps to improve the donation process and donor compliance. The aim of the present study was to evaluate donor vigilance data in whole blood and plasmapheresis donors of a blood donor service. Donors fulfilling current national and European eligibility criteria underwent whole blood and plasmapheresis donation (PCS and MCS+ (Haemonetics, Braintree, USA), A 200 (Fenwal, Round Lake, USA). Whole blood was collected at fixed and mobile sites while plasmaphereses were performed at 8 plasma centers. From 2011 to 2013 donor information was provided for gender, age, body weight, height, first and repeat donation. Donors were monitored for venipuncture and circulatory associated side effects. The total incidences of adverse events were 5004 (0.56%) in repeat donors and 2111 (2.78%) in first time donors for whole blood donation and 3323 (1.01%) and 514 (7.96%) for plasmaphereses, respectively. Circulatory associated events were 2679 (0.30%) for whole blood donation and 1624 (0.49%) for plasmaphereses. Our donor vigilance data of a blood transfusion service show that whole blood and plasmapheresis are safe with low incidences of adverse events. Repeat donation and age are predictors for low rates of adverse events. On the other hand, first time donation and female gender were associated with higher incidences of adverse events.

High-performance electronics require long carrier lifetimes within their silicon crystals. This paper reports the effects of thermal donors on the lifetimes of carriers in as-grown n-type silicon crystals grown by the Czochralski method. We grew silicon crystals with two different concentrations of thermal donors using the following two cooling processes: one was cooled with a 4-h halt after detaching the crystal from the melt, and the other was cooled continuously. The crystal grown with the cooling halt contained higher concentrations of thermal donors of the order of 1 × 1013 cm-3, while the crystal without the halt had no thermal donors. The measured bulk lifetimes were in the range of 15-18 ms. We concluded that thermal donors in Czochralski-grown silicon crystals do not act to reduce their lifetimes.

Polymalic acid (PMA) is a water-soluble polyester with many attractive properties for biomedical application. Its monomer L-malic acid is widely used in the food industry and also a potential C4 platform chemical. Cofactor and CO2 donor involved in the reductive routes were investigated for PMA production by Aureobasidium pullulans. Biotin as the key cofactor of pyruvate carboxylase was favor for the PMA biosynthesis. Na2CO3 as CO2 donor can obviously improved PMA titer when compared with no CO2 supplier NaOH, and also exhibit more advantages than the other donor CaCO3 because of its water-soluble characteristic. A combinational process with addition of biotin 70 mg/L and Na2CO3 as the CO2 donor was scaled-up in 50 L fermentor, achieving the high product 34.3 g/L of PMA and productivity of 0.41 g/L h. This process provides an efficient and economical way for PMA and malic acid production, and is promising for industrial application.

A political economy analysis of decision-making on natural disaster preparedness in Kenya.

PubMed

Rono-Bett, Karen C

2018-01-01

Most deaths from natural disasters occur in low- or middle-income countries; among them, countries in the Horn of Africa - where Kenya lies. Between September 2015 and September 2016, 23.4 million people in this region faced food insecurity because of the 2015 El Niño, characterised by floods and droughts. The importance of effective government decision-making on preparedness and response are critical to saving lives during such disasters. But this decision-making process occurs in a political context which is marred by uncertainty with other factors at play. Yet, good practice requires making investments on a 'no-regrets' basis. This article looks at the factors influencing Kenya's decision-making process for natural disasters, the preparedness for the 2015 El Niño as a case study. I explored what stakeholders understand by 'no-regrets investments' and its application. I assessed financial allocations by government and donors to disaster preparedness. Based on key informant interviews, focus group discussions and financial analyses, this article presents evidence at national and subnational levels. The findings indicate that in making decisions relating to preparedness, the government seeks information primarily from sources it trusts - other government departments, its communities and the media. With no existing legal frameworks guiding Kenya's disaster preparedness, the coordination of preparedness is not strong. It appears that there is a lack of political will to prioritise these frameworks. The no-regrets approach is applied predominantly by non-state actors. Because there have been 'non-events' in the past, government has become overcautious in committing resources on a no-regrets basis. Government allocation to preparedness exceeds donor funding by almost tenfold.

In Tanzania, there is paucity of data for monitoring laboratory medicine including haematology. This therefore calls for audits of practices in haematology and blood transfusion in order to provide appraise practice and devise strategies that would result in improved quality of health care services. This descriptive cross-sectional study which audited laboratory practice in haematology and blood transfusion at Muhimbili National Hospital (MNH) aimed at assessing the pre-analytical stage of laboratory investigations including laboratory request forms and handling specimen processing in the haematology laboratory and assessing the chain from donor selection, blood component processing to administration of blood during transfusion. A national standard checklist was used to audit the laboratory request forms (LRF), phlebotomists' practices on handling and assessing the from donor selection to administration 6f blood during transfusion. Both interview and observations were used. A total of 195 LRF were audited and 100% of had incomplete information such as patients' identification numbers, time sample ordered, reason for request, summary of clinical assessment and differential diagnoses. The labelling of specimens was poorly done by phlebotomists/clinicians in 82% of the specimens. Also 65% (132/202) of the blood samples delivered in the haematology laboratory did not contain the recommended volume of blood. There was no laboratory request form specific for ordering blood and there were no guidelines for indication of blood transfusion in the wards/ clinics. The blood transfusion laboratory section was not participating in external quality assessment and the hospital transfusion committee was not in operation. It is recommended that a referral hospital like MNH should have a transfusion committee to provide an active forum to facilitate communication between those involved with transfusion, monitor, coordinate and audit blood transfusion practices as per national guidelines.

Alternative Donor Graft Sources for Adults with Hematologic Malignancies: A Donor for All Patients in 2017!

PubMed

Kindwall-Keller, Tamila L; Ballen, Karen K

2017-09-01

Hematopoietic stem cell transplant (HSCT) is potentially curative for a wide variety of malignant diseases, including acute and leukemias, lymphoma, and myelodysplasia. Choice of a stem cell donor is dependent on donor availability, donor compatibility and health, recipient disease type, and recipient condition. Current sources of stem cell donation for HSCT are matched sibling donors (MSDs), matched unrelated donors (MUDs), 1-antigen mismatched unrelated donors (MMUDs), haploidentical donors (haplo), and umbilical cord blood (UCB) units. Historically, preferred donors for HSCT have been human leukocyte antigen (HLA)-matched sibling donors; however, only about 30% of U.S. patients will have a MSD available. The majority of patients referred for HSCT will require an alternative donor graft: MUD, MMUD, UCB, or haplo. The likelihood of finding a MUD varies depending on the ethnicity of the recipient. White Caucasians of European descent have the greatest chance of finding a MUD. Chances of finding a MUD are significantly less for African-American or Hispanic recipients due to HLA polymorphisms. Therefore, MMUD, UCB, and haplo donor graft sources expand the donor pool for recipients who do not have a MSD or MUD available. Given the variety of different donor stem cell sources available today, nearly every patient who needs an allogeneic HSCT has a potential donor in 2017. All transplant-eligible patients with hematologic malignancies should be evaluated by a transplant center to determine if HSCT is a viable treatment option for their underlying disease process. The goal of this review is to increase the awareness of oncology practitioners to the availability of alternative donor stem cell transplants for patients with hematologic malignancies. Despite new agents, stem cell transplant remains the only curative therapy for many patients with acute and chronic leukemia, myelodysplasia, and lymphoma. Given the variety of different donor stem cell sources available today, nearly every patient who needs an allogeneic stem cell transplant will have a donor. © AlphaMed Press 2017.

The Global Fund: managing great expectations.

The Global Fund to fight AIDS, Tuberculosis, and Malaria was created to increase funds to combat these three devastating diseases. We report interim findings, based on interviews with 137 national-level respondents that track early implementation processes in four African countries. Country coordinating mechanisms (CCMs) are country-level partnerships, which were formed quickly to develop and submit grant proposals to the Global Fund. CCM members were often ineffective at representing their constituencies and encountered obstacles in participating in CCM processes. Delay in dissemination of guidelines from the Global Fund led to uncertainty among members about the function of these new partnerships. Respondents expressed most concern about the limited capacity of fund recipients--government and non-government--to meet Global Fund conditions for performance-based disbursement. Delays in payment of funds to implementing agencies have frustrated rapid financing of disease control interventions. The Global Fund is one of several new global initiatives superimposed on existing country systems to finance the control of HIV/AIDS. New and existing donors need to coordinate assistance to developing countries by bringing together funding, planning, management, and reporting systems if global goals for disease control are to be achieved.

Engaging therapeutic citizenship and clientship: Untangling the reasons for therapeutic pacifism among people living with HIV in urban Zambia.

Patterson, Amy S

2016-10-01

This article explores the reasons for therapeutic pacifism among people living with HIV (PLHIVs) in urban Zambia. It contributes to a growing ethnography on global health, biosociality, and patient-provider dynamics. Therapeutic citizenship is a biopolitical citizenship that includes claims and ethical projects that emerge from techniques to control and manage bodies. In some contexts, therapeutic citizenship has included activism and claims-making against local, national, and international power brokers. This article investigates therapeutic citizenship in the specific context of impoverished urban Zambian compounds, sites of food insecurity, unemployment, and political exclusion, as well as targets for donor, NGO, and faith-based organisation projects and PLHIV support group proliferation. The article utilises data from participant observations at two Lusaka AIDS clinics, interviews, and focused discussions with support groups of PLHIVs. It argues that PLHIVs continuously negotiate subjectivities related to kinship, clientship, religious belief, and political citizenship in processes that complicate therapeutic citizenship. Rather than fostering participation in PLHIV support groups or challenging 'politics as usual' through activist claims-making to institutions of biopower, these processes lead to therapeutic pacifism.

Organic photovoltaic devices comprising solution-processed substituted metal-phthalocyanines and exhibiting near-IR photo-sensitivity

Organic photovoltaic (OPV) devices are disclosed. An exemplary device has first and second electrodes and an organic, photovoltaically active zone located between the first and second electrodes. The photovoltaically active zone includes an organic electron-donor material and an organic electron-acceptor material. The electron-donor material includes one or more trivalent- or tetravalent-metal phthalocyanines with alkylchalcogenide ring substituents, and is soluble in at least one organic solvent. This solubility facilitates liquid-processability of the donor material, including formation of thin-films, on an unlimited scale to form planar and bulk heterojunctions in organic OPVs. These donor materials are photovoltaically active in both visible and near-IR wavelengths of light, enabling more of the solar spectrum, for example, to be applied to producing electricity. Also disclosed are methods for producing the metalated phthalocyanines and actual devices.

Imprisoned and imperiled: access to HIV and TB prevention and treatment, and denial of human rights, in Zambian prisons

Background Although HIV and tuberculosis (TB) prevalence are high in prisons throughout sub-Saharan Africa, little research has been conducted on factors related to prevention, testing and treatment services. Methods To better understand the relationship between prison conditions, the criminal justice system, and HIV and TB in Zambian prisons, we conducted a mixed-method study, including: facility assessments and in-depth interviews with 246 prisoners and 30 prison officers at six Zambian prisons; a review of Zambian legislation and policy governing prisons and the criminal justice system; and 46 key informant interviews with government and non-governmental organization officials and representatives of international agencies and donors. Results The facility assessments, in-depth interviews and key informant interviews found serious barriers to HIV and TB prevention and treatment, and extended pre-trial detention that contributed to overcrowded conditions. Disparities both between prisons and among different categories of prisoners within prisons were noted, with juveniles, women, pre-trial detainees and immigration detainees significantly less likely to access health services. Conclusions Current conditions and the lack of available medical care in Zambia's prisons violate human rights protections and threaten prisoners' health. In order to protect the health of prisoners, prison-based health services, linkages to community-based health care, general prison conditions and failures of the criminal justice system that exacerbate overcrowding must be immediately improved. International donors should work with the Zambian government to support prison and justice system reform and ensure that their provision of funding in such areas as health services respect human rights standards, including non-discrimination. Human rights protections against torture and cruel, inhuman or degrading treatment, and criminal justice system rights, are essential to curbing the spread of HIV and TB in Zambian prisons, and to achieving broader goals to reduce HIV and TB in Zambia.

UbiG is a SAM-dependent O-methyltransferase, catalyzing two O-methyl transfer steps for ubiquinone biosynthesis in Escherichia coli. UbiG possesses a unique sequence insertion between β4 and α10, which is used for membrane lipid interaction. Interestingly, this sequence insertion also covers the methyl donor binding pocket. Thus, the relationship between membrane binding and entrance of the methyl donor of UbiG during the O-methyl transfer process is a question that deserves further exploration. In this study, we reveal that the membrane-binding region of UbiG gates the entrance of methyl donor. When bound with liposome, UbiG displays an enhanced binding ability toward the methyl donor product S-adenosylhomocysteine. We further employ protein engineering strategies to design UbiG mutants by truncating the membrane interacting region or making it more flexible. The ITC results show that the binding affinity of these mutants to SAH increases significantly compared with that of the wild-type UbiG. Moreover, we determine the structure of UbiG∆(165-187) in complex with SAH. Collectively, our results provide a new angle to cognize the relationship between membrane binding and entrance of the methyl donor of UbiG, which is of benefit for better understanding the O-methyl transfer process for ubiquinone biosynthesis.

Organic photosensitizers with a heteroleptic dual donor for dye-sensitized solar cells.

Kim, Joo Young; Kim, Young Sik

2012-04-01

Using DFT and TDDFT calculations, we investigated the substitution effect in the electronic and optical properties of dye sensitizers with a dual donor composed of triphenylamine and/or indoline moieties. Due to replacement with the dual donor moieties, the HOMO levels were split into HOMO and HOMO - 1 levels, and the bandgaps between the HOMO and LUMO levels decreased, leading to the creation of bathochromically extended absorption spectra. Nearly degenerated splitting of the HOMO levels resulted from the similarity of the electronic structure between the HOMO and the HOMO - 1 levels, delocalized over both dual-donor moieties, when replacing the dual donors. It was shown that the additional electron-donating group creates an additional absorption band and causes a cascading two-electron process aiding the charge separation process. Owing to a more panchromatic attribute, easier energy transfer and feasible retardation of the recombination between the injected electrons and the electrolyte, it is expected that dyeTI will show better performance than the other dyes (dyeT dyeTT and dyeIT) as denoted here in terms of the conversion efficiency of dye-sensitized solar cells (DSSCs). This work presents the probable benefits of dye sensitizers with dual-donor moieties and provides insight into the development of more efficient dye sensitizers for DSSCs through modification of the Frontier molecular orbitals.

Using donor conception treatment for family building brings challenges as well as rewards. As social model approaches to managing genetic difference within families gradually replace earlier medical models, parents are encouraged to be open with their children about their origins amidst greater social acceptance. Little is known about effective interventions to help prospective parents prepare for such family life. A survey was sent to participants in 16 Preparation for Parenthood workshops run in England by Donor Conception Network, a peer support organisation, between 2008 and 2010. The 79 respondents (32.4% response) included heterosexual couples, lesbian couples and single women considering sperm, egg or double donation. In 86% couples, both partners responded. The use of a range of techniques, a family lifespan approach, facilitators with personal as well as professional experience, medical and psychosocial specialists, and access to peer support were well received. Results suggest the value of attending cognitive and affective processes, acknowledging the impact of stigma and discussing how the donor's biography/presence can be conjoined with that of the new family. Findings suggest workshop approaches to donor conception parenthood preparation can be useful for prospective lesbian/single women/heterosexual-headed families considering donor conception. Such interventions have not previously been reported.

Human milk, widely understood to be beneficial for infants, can be lifesaving for preterm neonates, especially in reducing the risk of necrotizing enterocolitis. Donor human milk (DHM) is an option when mothers are unable to provide milk or have an inadequate supply for their infants. Nonprofit donor human milk banks are established to provide safe, processed human milk from milk donated by healthy lactating mothers who have undergone a rigorous screening process. These milk banks, operating under the auspices of the Human Milk Banking Association of North America, obtain, process, and dispense human milk under strict guidelines set by the association. Increasing the supply of donor human milk to meet a dramatic increase in demand poses a significant challenge for nonprofit milk banks. Efforts to increase supply nationwide include education of providers, use of social media to engage potential donors, and outreach to news media. In parallel, milk banks are establishing regional depots to collect donations, and additional milk banks are being developed. This article describes the current nonprofit milk bank industry in the United States, its challenges, and its future prospects. © 2013 by the American College of Nurse‐Midwives.

Triphenylamine-Based Push–Pull Molecule for Photovoltaic Applications: From Synthesis to Ultrafast Device Photophysics

PubMed Central

2017-01-01

Small push–pull molecules attract much attention as prospective donor materials for organic solar cells (OSCs). By chemical engineering, it is possible to combine a number of attractive properties such as broad absorption, efficient charge separation, and vacuum and solution processabilities in a single molecule. Here we report the synthesis and early time photophysics of such a molecule, TPA-2T-DCV-Me, based on the triphenylamine (TPA) donor core and dicyanovinyl (DCV) acceptor end group connected by a thiophene bridge. Using time-resolved photoinduced absorption and photoluminescence, we demonstrate that in blends with [70]PCBM the molecule works both as an electron donor and hole acceptor, thereby allowing for two independent channels of charge generation. The charge-generation process is followed by the recombination of interfacial charge transfer states that takes place on the subnanosecond time scale as revealed by time-resolved photoluminescence and nongeminate recombination as follows from the OSC performance. Our findings demonstrate the potential of TPA-DCV-based molecules as donor materials for both solution-processed and vacuum-deposited OSCs. PMID:28413568

In times of shrinking donor population, the recruitment of donors is of utmost importance. Recruitment can be done by personal communication, advertisement/information, classical mass media (newspaper, radio, TV) or new computerized media. The aim of this study was to gain information about the donors' demands of an Internet presentation of a blood transfusion service. Between October and December 2004 inclusive, prospective donors were asked to complete a survey about the impact of Internet information for blood donors. The survey contained questions measuring demographics, education and motivation for blood donation. In addition, the survey included questions that measured Internet access, duration of online time and donors' demands for an Internet presentation of a blood transfusion service. Donors were asked to tick a box with predefined answers. In cases where no options were applied, donors were requested to specify their answers. One hundred and fourteen prospective donors (71 female, 43 male) with a median age of 25 years (range 18-57 years) completed the survey. Most donors (57.9%) were 18-30 years old. Forty-two (36.8%) of the surveyed donors were repeat donors, whereas 72 (63.2%) were first-time donors. The majority of donors were informed about blood donation from relatives or friends (70.7% repeat donors and 67.7% first-time donors). Most of them had Internet access (85.7% repeat donors and 90.3% first-time donors). Exclusive use of private access was more often reported in repeat donors (77.8%), whereas both private and professional access was more frequently used in first-time donors (32.3%). Most donors used the Internet access daily, followed by weekly and monthly use. Multiple answers were given about the importance of desired information about the topic 'blood donation'. Both first-time and repeat donors wanted to be informed about organizational details of blood donation such as opening times, eligibility criteria, donation process and the kind of donation, e.g. whole blood donation or apheresis donation. Information about the use of the donated blood products, remuneration and laboratory tests performed were also required. The Internet is an important new tool for the recruitment of prospective donors. Donors want to be informed about organizational details of the donation. In the meantime, we have implemented a homepage for our transfusion service meeting the demands of prospective donors.

Since the 1970s many tissue banks have been testing allograft heart valves (HVs) for Mycobacterium tuberculosis (MTB). Donor selection for low risk of tuberculosis (TB) was introduced in the 1980s and appears to have reduced the risk of TB transmission. Regulatory guidance does not specify testing for TB, but does exclude donors with a recent history of TB. This survey of HV international bank practices revealed variations in donor selection, testing and processing of valves. Participant banks (from Europe and the USA) reported that over a period of 15 years, HV tissues from 38,413 donors were banked and 32,289 donors were tested for TB, none being positive. HV-associated tissue from 27,840 donors was stained and underwent microscopy; none of these were positive for acid-fast bacilli (AFB). Non-tuberculosis mycobacteria (NTBM) were detected by culture on 24 HVs. It is recommended that HV banks employ donor selection to exclude donors at risk of TB, to culture material for mycobacteria, and to investigate potential sources when clusters of NTBM are found to facilitate corrective and preventative actions.

Human dissection commonly occurs early in the undergraduate medical school curriculum, thus presenting an immediate opportunity for educators to teach and encourage humanistic qualities of respect, empathy, and compassion. The purpose of this study was to measure the impact of the Donor Luncheon, a unique program in which medical students meet the families of the anatomical donor prior to dissection in the anatomy course at the University of Oklahoma College of Medicine. Students were randomized into groups of 8 to attend the luncheon and either met with family of the donor or attended the luncheon with no donor family present. A questionnaire measured students' attitudes at 2 weeks, 6 weeks, and at the conclusion of the anatomy course. Factor analysis revealed 5 scales. Analysis revealed statistically significant differences across time for Donor as Person, Dissection Process, and Donor as Patient and statistically significant differences between groups for Donor as Person and Donor as Patient. These results suggest that this program can provide students with the opportunity to maintain more humanistic attitudes at the beginning of their medical education career.

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

PubMed

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

2009-10-01

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

Anesthesia Management of Organ Donors.

Xia, Victor W; Braunfeld, Michelle

2017-09-01

The shortage of suitable organs is the biggest obstacle for transplants. At present, most organs for transplant in the United States are from donation after neurologic determination of death (brain death). Potential organs for transplant need to maintain their viability during a series of insults, including the original disease, physiologic derangements during the dying process, ischemia, and reperfusion. Proper donor management before, during, and after procurement has potential to increase the number and quality of organs from donors. Anesthesiologists need to understand the physiologic derangements associated with brain death and the updated donor management during the periprocurement period. Copyright © 2017 Elsevier Inc.

Studies on living donors from the donors' perspective show that the donation process involves both positive and negative feelings involving vulnerability. Qualitative studies of living kidney, liver, and allogeneic hematopoietic stem cell donors have not previously been merged in the same analysis. Therefore, our aim was to synthesize current knowledge of these donors' experiences to deepen understanding of the meaning of being a living donor for the purpose of saving or extending someone's life. The meta-ethnography steps presented by Noblit and Hare in 1988 were used. Forty-one qualitative studies from 1968 to 2016 that fulfilled the inclusion criteria were analyzed. The studies comprised experiences of over 670 donors. The time since donation varied from 2 days to 29 years. A majority of the studies, 25 of 41, were on living kidney donors. The synthesis revealed that the essential meaning of being a donor is doing what one feels one has to do, involving 6 themes; A sense of responsibility, loneliness and abandonment, suffering, pride and gratitude, a sense of togetherness, and a life changing event. The main issue is that one donates irrespective of what one donates. The relationship to the recipient determines the motives for donation. The deeper insight into the donors' experiences provides implications for their psychological care.

The marked decline in the number of sperm donors recruited in the UK has been largely attributed to changes in regulations and in particular those related to the removal of anonymity. After a 5-year period of inactivity, the sperm donor bank in Nottingham was provided with limited resources to try and recruit donors who were willing to be identified on the HFEA register. Marketing was sporadic and at first low cost and the enquiry rate only increased significantly when the centre's website became operational and higher cost advertising was used. Over a 4-year period, a total of 151 enquiries gave rise to 14 useable donors at a cost of approximately £5,500 each. Donor sperm was generally of high quality having been density gradient prepared prior to cryopreservation and provided an overall ongoing pregnancy rate of 21.6% and 45.6% by IUI and IVF, respectively. The overall exercise demonstrated that identifiable donors were coming forward but in lower numbers compared to those observed before 2005. At current treatment prices, centres should be aware that recouping the costs of donor recruitment and processing may be difficult and that the cost of both donor sperm and donor insemination are likely to rise significantly.

Fragmented blood transfusion services along with an unmotivated blood donation culture often leads to blood shortage. Donor retention is crucial to meet the increasing blood demand, and adverse donor reactions have a negative impact on donor return. The aim of this study was to estimate adverse donor reactions and identify any demographic association.  . We conducted a prospective study between January 2011 and December 2013. A total of 41,759 healthy donors were enrolled. Professionally trained donor attendants drew blood and all donors were observed during and following donation for possible adverse events for 20 minutes. Blood donors were asked to report if they suffered from any delayed adverse consequences.  . Out of 41,759 blood donors, 537 (1.3%) experienced adverse reactions. The incidence was one in every 78 donations. The mean age of donors who experienced adverse events was 26.0±6.8 years, and all were male. Out of 537 donors, 429 (80%) developed vasovagal reaction (VVR), 133 (25%) had nausea, 63 (12%) fainted, 35 (6%) developed hyperventilation, 9 (2%) had delayed syncope, and 9 (2%) developed hematoma. Arterial prick, nerve injury, cardiac arrest, and seizures were not observed. Donors aged less than < 30 years and weighing < 70 kg were significantly associated with VVR, hyperventilation, and nausea (p < 0.005). Undergraduates and Urdu speaking donors also had a significant association with fainting and nausea, respectively (p < 0.05).  . The prevalence of adverse events was low at our tertiary center. A VVR was the predominant adverse reaction and was associated with age and weight. Our study highlights the importance of these parameters in the donation process. A well-trained and experienced phlebotomist and pre-evaluation counseling of blood donors could further minimize the adverse reactions.

Potential applications of somatic cell nuclear transfer to agriculture and medicine are currently constrained by low efficiency and high rates of embryonic, fetal, and neonatal loss. Nuclear transfer efficiency in cattle was compared between three donor-cell treatments from a single animal, between four donor-cell treatments in sequential stages of differentiation from a single cell lineage and genotype, and between the same cell type in two donors. Cumulus and granulosa donor cells resulted in a greater proportion of viable day-7 embryos than ear-skin cells; pregnancy rate and losses were not different among treatments. The least differentiated cell type in the follicular cell lineage, preantral follicle cells, resulted in fewer cloned blastocysts (11%) than cumulus (30%), granulosa (23%), and luteal (25%) donor cells. Cloned blastocysts that did develop from preantral follicle cells (75%) were more likely to progress through implantation into later stages of pregnancy than cloned blastocysts from cumulus (10%), granulosa (9%), and luteal (11%) donor cells (p < 0.05). Day-7 embryo development from granulosa cells was similar between two donors (19 vs. 24%) and proved to be a poor indicator of further development as day-30 pregnancy rates varied threefold between donors (48 vs. 15%, p < 0.05). Results reported here emphasize the crucial role of the nuclear donor cell in the outcome of the nuclear-transfer process.

Achieving donor repetition and motivation by block leaders among current blood donors.

This paper presents an explicative model on the recommendation of donating blood made to relatives and friends by current donors. This model establishes satisfaction and intention to return as direct antecedents, and the quality perceived in the donation process and the existence of inhibitors as indirect antecedents. The results show that (1) the perceived quality has a positive influence on satisfaction and intention to return; (2) the intention to donate again depends positively on satisfaction, but negatively on the existence of internal and external inhibitors; and lastly (3) the recommendation to donate depends on donor satisfaction and their intention to return to donate, this being the most influential factor. At the same time, we contrasted how the model does not vary, whether it is a first-time donor or a repeat donor. Copyright © 2012 Elsevier Ltd. All rights reserved.

Inadequate organ donation limits transplantation for many in need of a life-saving organ. Race of donor families and requesting coordinators may impact the authorization rate for organ donation. We evaluated authorization rates for organ donation within the New York Organ Donor Network by race during 2009 and 2010. The donation authorization rate varied considerably according to the race of the donor. The authorization rate was 57% for Hispanic, 53% for Caucasian, 48% for African-American, and 23% for Asian donor families. Fifty-five percent of donor families agreed to donation when there was racial concordance between coordinator and donor. Donation authorization was 49% when a racial mis-match existed. When adjusted for coordinator training and experience, racial discordance had a lesser impact on authorization rates. Our findings suggest the need for education and communication strategies to overcome racial-associated perception during the organ donation process. PMID:23303969

Based on anthropological fieldwork among Danish organ donor families and hospital staff in neurointensive care units, this article explores the transformative practices of hope in Danish organ donation. Focusing on various phases of the organ donation process, I demonstrate how families and professionals practice hope in astounding ways: when hoping for organs, when hoping for the end of patient suffering, when hoping for the usability of the donor body, and when hoping to help future donor families by sharing painful experiences. By focusing on such practices and transformations of hope, this article sheds light on the social negotiations of life and death among families and staffs in medical contexts and describes how the dignity of the deceased donor and the usability of the donor body are closely connected in family attempts to make donation decisions meaningful during and after a tragic death. © 2016 by the American Anthropological Association.

In resource-poor settings, the accountability for reasonableness (A4R) has been identified as an important advance in priority setting that helps to operationalize fair priority setting in specific contexts. The four conditions of A4R are backed by theory, not evidence, that conformance with them improves the priority setting decisions. This paper describes the healthcare priority setting processes in Malindi district, Kenya, prior to the implementation of A4R in 2008 and evaluates the process for its conformance with the conditions for A4R. In-depth interviews and focus group discussions with key players in the Malindi district health system and a review of key policy documents and national guidelines show that the priority setting process in the district relies heavily on guidelines from the national level, making it more of a vertical, top-down orientation. Multilateral and donor agencies, national government, budgetary requirements, traditions and local culture influence the process. The four conditions of A4R are present within the priority setting process, albeit to varying degrees and referred to by different terms. There exists an opportunity for A4R to provide a guiding approach within which its four conditions can be strengthened and assessed to establish whether conformance helps improve on the priority setting process.

Why do policies change? Institutions, interests, ideas and networks in three cases of policy reform.

2016-11-01

Policy researchers have used various categories of variables to explain why policies change, including those related to institutions, interests and ideas. Recent research has paid growing attention to the role of policy networks-the actors involved in policy-making, their relationships with each other, and the structure formed by those relationships-in policy reform across settings and issues; however, this literature has largely ignored the theoretical integration of networks with other policy theories, including the '3Is' of institutions, interests and ideas. This article proposes a conceptual framework integrating these variables and tests it on three cases of policy change in Burkina Faso, addressing the need for theoretical integration with networks as well as the broader aim of theory-driven health policy analysis research in low- and middle-income countries. We use historical process tracing, a type of comparative case study, to interpret and compare documents and in-depth interview data within and between cases. We found that while network changes were indeed associated with policy reform, this relationship was mediated by one or more of institutions, interests and ideas. In a context of high donor dependency, new donor rules affected the composition and structure of actors in the networks, which enabled the entry and dissemination of new ideas and shifts in the overall balance of interest power ultimately leading to policy change. The case of strategic networking occurred in only one case, by civil society actors, suggesting that network change is rarely the spark that initiates the process towards policy change. This analysis highlights the important role of changes in institutions and ideas to drive policymaking, but hints that network change is a necessary intermediate step in these processes. © The Author 2016.

Stakeholders’ participation in planning and priority setting in the context of a decentralised health care system: the case of prevention of mother to child transmission of HIV programme in Tanzania

PubMed Central

2013-01-01

Background In Tanzania, decentralisation processes and reforms in the health sector aimed at improving planning and accountability in the sector. As a result, districts were given authority to undertake local planning and set priorities as well as allocate resources fairly to promote the health of a population with varied needs. Nevertheless, priority setting in the health care service has remained a challenge. The study assessed the priority setting processes in the planning of the prevention of mother to child transmission of HIV (PMTCT) programme at the district level in Tanzania. Methods This qualitative study was conducted in Mbarali district, south-western Tanzania. The study applied in-depth interviews and focus group discussions in the data collection. Informants included members of the Council Health Management Team, regional PMTCT managers and health facility providers. Results Two plans were reported where PMTCT activities could be accommodated; the Comprehensive Council Health Plan and the Regional PMTCT Plan that was donor funded. As donors had their own globally defined priorities, it proved difficult for district and regional managers to accommodate locally defined PMTCT priorities in these plans. As a result few of these were funded. Guidelines and main priority areas of the Ministry of Health and Social Welfare (MoHSW) also impacted on the ability of the districts and regions to act, undermining the effectiveness of the decentralisation policy in the health sector. Conclusion The challenges in the priority setting processes revealed within the PMTCT initiative indicate substantial weaknesses in implementing the Tanzania decentralisation policy. There is an urgent need to revive the strategies and aims of the decentralisation policy at all levels of the health care system with a view to improving health service delivery. PMID:23849730

Impact of blood manufacturing and donor characteristics on membrane water permeability and in vitro quality parameters during hypothermic storage of red blood cells.

2018-02-01

Several factors have been proposed to influence the red blood cell storage lesion including storage duration, blood component manufacturing methodology, and donor characteristics [1,18]. The objectives of this study were to determine the impact of manufacturing method and donor characteristics on water permeability and membrane quality parameters. Red blood cell units were obtained from volunteer blood donors and grouped according to the manufacturing method and donor characteristics of sex and age. Membrane water permeability and membrane quality parameters, including deformability, hemolysis, osmotic fragility, hematologic indices, supernatant potassium, and supernatant sodium, were determined on day 5 ± 2, day 21, and day 42. Regression analysis was applied to evaluate the contribution of storage duration, manufacturing method, and donor characteristics on storage lesion. This study found that units processed using a whole blood filtration manufacturing method exhibited significantly higher membrane water permeability throughout storage compared to units manufactured using red cell filtration. Additionally, significant differences in hemolysis, supernatant potassium, and supernatant sodium were seen between manufacturing methods, however there were no significance differences between donor age and sex groups. Findings of this study suggest that the membrane-related storage lesion is initiated prior to the first day of storage with contributions by both blood manufacturing process and donor variability. The findings of this work highlight the importance of characterizing membrane water permeability during storage as it can be a predictor of the biophysical and chemical changes that affect the quality of stored red blood cells during hypothermic storage.

Voluntary blood donation rates are low in sub-Saharan Africa. Sociobehavioral factors such as a belief that donated blood would be used for performing rituals deter people from donating blood. There is a need for culturally appropriate communication interventions to encourage individuals to donate blood. Health care interventions that use mobile phones have increased in developing countries, although many of them focus on SMS text messaging (short message service, SMS). A unique feature of mobile phones that has so far not been used for aiding blood donation is caller tunes. Caller tunes replace the ringing sound heard by a caller to a mobile phone before the called party answers the call. In African countries such as Ghana, instead of the typical ringing sound, a caller may hear a message or song. Despite the popularity of such caller tunes, there is a lack of empirical studies on their potential use for promoting blood donation. The aim of this study was to use the technology acceptance model to explore the influence of the factors-perceived ease of use, perceived usefulness, attitude, and free of cost-on intentions of blood or nonblood donors to download blood donation-themed caller tunes to promote blood donation, if available. A total of 478 blood donors and 477 nonblood donors were purposively sampled for an interviewer-administered questionnaire survey at blood donation sites in Accra, Ghana. Data were analyzed using descriptive statistics, exploratory factor analysis, and confirmatory factory analysis or structural equation modeling, leading to hypothesis testing to examine factors that determine intention to use caller tunes for blood donation among blood or nonblood donors who use or do not use mobile phone caller tunes. Perceived usefulness had a significant effect on intention to use caller tunes among blood donors with caller tunes (beta=.293, P<.001), blood donors without caller tunes (beta=.165, P=.02, nonblood donors with caller tunes (beta=.278, P<.001), and nonblood donors without caller tunes (beta=.164, P=.01). Attitudes had significant effect on intention to use caller tunes among blood donors without caller tunes (beta=.351, P<.001), nonblood donors with caller tunes (beta=.384, P<.001), nonblood donors without caller tunes (beta=.539, P<.001) but not among blood donors with caller tunes (beta=.056, P=.44). The effect of free-of-cost caller tunes on the intention to use for blood donation was statistically significant (beta=.169, P<.001) only in the case of nonblood donors without caller tunes, whereas this path was statistically not significant in other models. Our results provide empirical evidence for designing caller tunes to promote blood donation in Ghana. The study found that making caller tunes free is particularly relevant for nonblood donors with no caller tunes. ©Bernard Appiah, James N Burdine, Ammar Aftab, Lucy Asamoah-Akuoko, David A Anum, Irene A Kretchy, Elfreda W Samman, Patience B Appiah, Imelda Bates.

2014-01-01

Background The collapse of the Soviet Union in 1991 resulted in a transition from centrally planned socialist systems to largely free-market systems for post-Soviet states. The health systems of Central Asian Post-Soviet (CAPS) countries (Kyrgyzstan, Mongolia, Tajikistan, Turkmenistan, and Uzbekistan) have undergone a profound revolution. External development partners have been crucial to this reorientation through financial and technical support, though both relationships and outcomes have varied. This research provides a comparative review of the development assistance provided in the health systems of CAPS countries and proposes future policy options to improve the effectiveness of development. Design Extensive documentary review was conducted using Pubmed, Medline/Ovid, Scopus, and Google scholar search engines, local websites, donor reports, and grey literature. The review was supplemented by key informant interviews and participant observation. Findings The collapse of the Soviet dominance of the region brought many health system challenges. Donors have played an essential role in the reform of health systems. However, as new aid beneficiaries, neither CAPS countries’ governments nor the donors had the experience of development collaboration in this context. The scale of development assistance for health in CAPS countries has been limited compared to other countries with similar income, partly due to their limited history with the donor community, lack of experience in managing donors, and a limited history of transparency in international dealings. Despite commonalities at the start, two distinctive trajectories formed in CAPS countries, due to their differing politics and governance context. Conclusions The influence of donors, both financially and technically, remains crucial to health sector reform, despite their relatively small contribution to overall health budgets. Kyrgyzstan, Mongolia, and Tajikistan have demonstrated more effective development cooperation and improved health outcomes; arguably, Uzbekistan and Turkmenistan have made slower progress in their health and socio-economic indices because of their resistance to open and accountable development relationships.

Hepatitis B virus infection generates carriers and 8% will evolve to a chronic phase. To perform a compilation of studies on hepatitis B in Chile and other sources of information to estimate the impact of this disease in our country. Published and unpublished evidence about the infection, in the general population and risk groups in our country, was compiled and reviewed critically. Informal interviews with experts, revision of the mandatory notification book of the Ministry of Health and collection of data from laboratories that study hepatitis B virus, were also carried out. The seroprevalence of chronic carriers in blood donors is nearly O.3%. Among risk groups such as health care personnel, the figure is O.7%, among homosexuals 29%, among HIV positive patients 30%, among sexual workers 2% and among children with chronic hemodialysis, 9%. Prevalence rate according to notified cases in 2004 was 1.8 x 100,000 inhabitants. Detection of viral hepatitis B surface antigen in laboratories occurs in 0.2% of donors and 1.396 of non donors. The seroprevalence of hepatitis B virus, the lack of notification, and the introduction of hepatitis B vaccine to our Regular Program of Immunizations, are arguments to develop in Chile a hepatitis B and C surveillance system.

Aims To examine the impact of telephone consent introduced in 2007 on the eye donation rate and to report the changing trend and potential for improvement in eye donation in Newcastle upon Tyne, UK. Methods Relevant data were retrospectively collected from the local eye retrieval database for two separate years, namely, 2006 (before the introduction of telephone consent) and 2010. All the hospitals within Newcastle were included in the study. Results From 2006 to 2010, there was a 3.5-fold increase in eye donation from 32 (of 2479 deaths) to 111 donors per year (of 2213 deaths) in Newcastle (P<0.001). Consent was obtained via face-to-face interview in all 32 (100%) and 59 (53.2%) donors in 2006 and 2010, respectively. Introduction of telephone consent increased the donation rate by an additional 88.1% (from 59 to 111 donors) in 2010 (P<0.001). In addition, there was a significant increase in medical notes of the deceased being reviewed from 27.1% (671/2479 cases) in 2006 to 62.4% (1382/2213 cases) in 2010 (P<0.001). Acceptance rate of eye donation was 45.7% (32/70) in 2006 and 49.6% (111/224) in 2010 (P=0.575). Acceptance rate was positively associated with registration on organ donor register (P<0.001) and telephone consent (P<0.001), but not with age (P=0.883), gender (P=0.234), or location of death (P=0.984) of the potential donors. Conclusion There has been a substantial improvement in eye donation rate in Newcastle over the recent years. Introduction of telephone consent and high-quality eye donation service serve as effective measures for increasing eye donation. PMID:26514245

One consequence of the legal diversity in Europe is that legal restrictions on treatments can be evaded by going abroad. Many French lesbian couples and single women are crossing the border to Belgium because they are denied access to treatments with donor sperm at home. This is the first qualitative research study into the experiences and moral perspectives of these women. Between June 2012 and May 2013, 11 lesbian couples and 2 single women were recruited at the department of reproductive medicine at Ghent University Hospital. The data from the semi-structured interviews was analysed using inductive thematic analysis. The results show that these women face several additional challenges to the already difficult process of cross-border treatment. Before they can start the treatment, they can only obtain information from the internet or from stories of friends who also went abroad for treatment with donor sperm. During the treatment, they need to find local clinics or physicians to monitor their cycle. Several women managed to game the French system to ensure partial reimbursement for their treatment when they were successful in finding a physician who was willing to prescribe drugs and perform tests. Most women had difficulties justifying their absence from work. In general these women felt that they were discriminated against and that their rights were not protected because of who they are. In that regard, the lack of legal recognition of the genetically unrelated partner in their country was particularly hard to cope with for the lesbian couples. These women have to develop many different strategies to deal with the difficulties they face during cross-border reproductive care. It is concluded that it is very important that they find a physician who is willing to support them in their 'baby project'. Copyright © 2014 Elsevier Ltd. All rights reserved.

Deceased donor kidneys are a scarce resource and there is debate about how to maximize the benefit from each donated kidney while ensuring equity of access to transplants. Allocation of kidneys to waitlisted patients is determined by a computer algorithm, but the decision to waitlist patients or accept the kidneys offered is largely at the discretion of nephrologists. This study aims to elicit nephrologists' perspectives on waitlisting patients for kidney transplant and the allocation of deceased kidneys. We conducted semistructured face-to-face interviews with adult and pediatric nephrologists from 15 Australian nephrology or transplant centers. Transcripts were analyzed for descriptive and analytical themes. 25 nephrologists participated. 5 major themes on waitlisting and deceased donor kidney allocation were identified: patient advocacy (championing their own patients, empowering patients, giving hope, individualizing judgments, patient preferences, and limited autonomy), professional and moral integrity (transparency, avoiding value judgments, and eliminating bias), protecting center reputation (gatekeeping), achieving equity (uniformity, avoiding discrimination, and fairness for specific populations), and maximizing societal benefit (prioritizing best use of kidney, resource implications, favoring social contribution, and improving efficiency of the allocation process). In making individual patient assessments, estimates about outcomes for a patient had to be resolved with whether it was reasonable from a broader societal perspective. Nephrologists expressed their primary responsibility in terms of giving their own patients access to a transplant and upholding professional integrity by maintaining transparency and avoiding value judgments and bias. However, nephrologists perceived an obligation to protect their center's reputation through the selection of "good" patients, and this caused some frustration. Despite having personal preferences for optimizing the balance between societal benefit and equity, nephrologists did not want direct responsibility for ensuring societal benefit in clinical practice. Rather, they placed the onus on policy makers and the community to reconcile such tensions and advocate for societal benefit. Copyright © 2011 National Kidney Foundation, Inc.

The South African National Blood Service collects more than 700,000 units of blood annually from a population in which 11.4% is infected with human immunodeficiency virus 1 (HIV-1). The prevalence of HIV-1 in blood donations increased to 0.26% (1:385) in 1998, indicating that a significant number of window-period infective units were entering the blood supply (risk 3.4/100,000). To determine whether the implementation of a new donor selection policy and educational program introduced in 1999 was associated with reductions in the incidence and prevalence of HIV-1 in blood donations and the reduced transmission risk. We compared the prevalence of HIV-1 in 880,534 blood donations collected from 1999 through 2000 with the 791,639 blood donations collected from 2001 through 2002. We estimated the incidence of HIV-1 in 93,378 (1999-2000) and 67,231 (2001-2002) first-time donations and the residual risk for all donations in 2001-2002 using the less-sensitive enzyme-linked immunoassay and incidence-window period model. All blood donors in the Inland region of the South African National Blood Service were analyzed. Donor clinics in high HIV prevalence areas were closed. Programs targeting repeat donors and youth were initiated and HIV risk behavior education programs were developed. Structured donor interviews and an enhanced donor self-exclusion questionnaire were institutionalized. The prevalence of HIV-1 in blood donations declined from 0.17% in 1999-2000 to 0.08% in 2001-2002 after the implementation of the new donor selection and education policy. The number of high-risk donations collected decreased from 2.6% to 1.7% (P<.001), and the likelihood of these donations being infected decreased from 4.8% to 3.25%. The likelihood of first-time donors being recently infected with HIV-1 decreased from 18% to 14% (P = .07) and respective incidence of high-risk donations collected decreased from 2.6% to 1.7%. Donations from the majority black population declined from 6.6% to 4.2% (P<.001). Analysis of HIV-1 incidence in 2001-2002 suggests a residual risk of collecting a window period infectious unit of 2.6/100,000. The implementation of enhanced education and selection policies in South Africa was associated with decreased prevalence of HIV-1 in blood donations.

Donor human milk has emerged as the preferred substrate to feed extremely preterm infants, when mother's own milk is unavailable. This article summarizes the clinical data demonstrating the safety, efficacy, and cost-effectiveness of feeding donor human milk to premature babies. It describes the current state of milk banking in North America, as well as other parts of the world, and the differing criteria for donor selection, current pasteurization techniques, and quality control measures. A risk assessment methodology is proposed, which would allow milk banks globally to assess the safety of their process and respond appropriately to differing risk environments. Copyright © 2013.

Cloning is a process that produces genetically identical organisms. However, the genomic degree of genetic resemblance in clones needs to be determined. In this report, the genomes of a cloned dog and its donor were compared. Compared with a human monozygotic twin, the genome of the cloned dog showed little difference from the genome of the nuclear donor dog in terms of single nucleotide variations, chromosomal instability, and telomere lengths. These findings suggest that cloning by somatic cell nuclear transfer produced an almost identical genome. The whole genome sequence data of donor and cloned dogs can provide a resource for further investigations on epigenetic contributions in phenotypic differences. PMID:24141358

Social support attenuates presyncopal reactions to blood donation.

PubMed

Hanson, Sarah A; France, Christopher R

2009-05-01

The experience of unpleasant blood donation reactions (e.g., dizziness, nausea, and fainting) has been linked to negative attitudes about donation and decreased likelihood of repeat donation. Consequently, interventions to reduce the adverse effects of blood donation are important and likely to increase donor retention. Based on laboratory studies suggesting that social support attenuates both physical and psychological responses to stress, the present study hypothesized that the presence of a supportive person during the donation process may help reduce reactions. A final sample of 65 men and women with fewer than three prior donations was randomly assigned to either donate blood as usual or donate with a supportive research assistant. Donors in the support condition were accompanied throughout the donation process by a female research assistant who provided encouragement, made reassuring remarks, and engaged in small talk. Donors in both conditions completed a series of questions to assess anxiety, experience of prefaint reactions, and willingness to provide a future donation. Compared to standard donation controls, donors in the social support condition reported fewer prefaint reactions (F(1,61) = 9.15, p = 0.004, eta(2)= 0.13) and greater likelihood of donating again within the next year (Z =-1.70, p < 0.05, one-tailed). Relatively novice donors report reduced reactions to blood donation when accompanied by a supportive individual, suggesting that social support may be a simple strategy to enhance the donation experience and possibly increase donor retention.

The spin of an electron bound to a single donor implanted in silicon is potentially useful for quantum information processing. We report on our efforts to measure and manipulate the spin of an electron bound to a single P donor in silicon. A low number of P donors are implanted using a self-aligned process into a silicon substrate in close proximity to a single-electron-transistor (SET) defined by lithographically patterned polysilicon gates. The SET is used to sense the occupancy of the electron on the donor and for spin read-out. An adjacent transmission line allows the application of microwave pulses to rotate the spin of the electron. We will present data from various experiments designed to exploit these capabilities. This work was performed, in part, at the Center for Integrated Nanotechnologies, a U.S. DOE Office of Basic Energy Sciences user facility. The work was supported by Sandia National Laboratories Directed Research and Development Program.

In this letter, we have studied the performance of AlGaN/GaN metal-insulator-semiconductor high electron mobility transistors (MIS-HEMTs) with different interface Si donor incorporation which is tuned during the deposition process of LPCVD-SiNx which is adopted as gate dielectric and passivation layer. Current collapse of the MIS-HEMTs without field plate is suppressed more effectively by increasing the SiH2Cl2/NH3 flow ratio and the normalized dynamic on-resistance (RON) is reduced two orders magnitude after off-state VDS stress of 600 V for 10 ms. Through interface characterization, we have found that the interface deep-level traps distribution with high Si donor incorporation by increasing the SiH2Cl2/NH3 flow ratio is lowered. It's indicated that the Si donors are most likely to fill and screen the deep-level traps at the interface resulting in the suppression of slow trapping process and the virtual gate effect. Although the Si donor incorporation brings about the increase of gate leakage current (IGS), no clear degradation of breakdown voltage can be seen by choosing appropriate SiH2Cl2/NH3 flow ratio.

Although peripheral blood stem cells (PBSCs) have replaced bone marrow (BM) as the most common unrelated donor progenitor cell product collected, a direct comparison of concurrent PBSC versus BM donation experiences has not been performed. We report a prospective study of 2726 BM and 6768 PBSC donors who underwent collection from 2004 to 2009. Pain and toxicities were assessed at baseline, during G-CSF administration, on the day of collection, within 48 hours of donation, and weekly until full recovery. Peak levels of pain and toxicities did not differ between the 2 donation processes for most donors. Among obese donors, PBSC donors were at increased risk of grade 2 to 4 pain as well as grade 2 to 4 toxicities during the pericollection period. In contrast, BM donors were more likely to experience grade 2 to 4 toxicities at 1 week and pain at 1 week and 1 month after the procedure. BM donors experienced slower recovery, with 3% still not fully recovered at 24 weeks, whereas 100% of PBSC donors had recovered. Other factors associated with toxicity included obesity, increasing age, and female sex. In summary, this study provides extensive detail regarding individualized risk patterns of PBSC versus BM donation toxicity, suggesting donor profiles that can be targeted with interventions to minimize toxicity.

Living organ donation involves significant out-of-pocket costs, which burden donor candidates and may be an obstacle to donation. There is a single US grant (the National Living Donor Assistance Center-NLDAC) to cover live donor travel costs. Although there may be center-specific variability in grant utilization, prospective donors-and their intended recipients-must also meet eligibility criteria. In fact, the NLDAC grant is used by <10% of US live donors annually. We studied 154 consecutive kidney donor clinic evaluations (November 1, 2014-August 30, 2015) to determine eligibility and usage patterns during the evaluation process. Of these, 63 (41%) were local, had travel benefits, or declined. Of the remaining 91 prospective donors who might have benefited from grant support, only 29 (32%) obtained the grant. The other 62 (68%) did not meet eligibility screening. The major reason prospective donors were ineligible was that the recipient's household income was outside the required means test (ie, >300% of the federal poverty level) (n=51; 82%). The remaining exclusions (n=11; 18%) included being a nondirected donor, not meeting residency requirements, and "other." Expanding NLDAC eligibility criteria-by broadening the recipient means test or by taking steps to eliminate it from the NLDAC charter-would reduce financial burdens associated with live donation. © 2016 John Wiley & Sons A/S.

Host heterogeneity affects both parasite transmission to and fitness on subsequent hosts

PubMed Central

Young, Kyle A.; Fox, Jordan; Jokela, Jukka

2017-01-01

Infectious disease dynamics depend on the speed, number and fitness of parasites transmitting from infected hosts (‘donors’) to parasite-naive ‘recipients’. Donor heterogeneity likely affects these three parameters, and may arise from variation between donors in traits including: (i) infection load, (ii) resistance, (iii) stage of infection, and (iv) previous experience of transmission. We used the Trinidadian guppy, Poecilia reticulata, and a directly transmitted monogenean ectoparasite, Gyrodactylus turnbulli, to experimentally explore how these sources of donor heterogeneity affect the three transmission parameters. We exposed parasite-naive recipients to donors (infected with a single parasite strain) differing in their infection traits, and found that donor infection traits had diverse and sometimes interactive effects on transmission. First, although transmission speed increased with donor infection load, the relationship was nonlinear. Second, while the number of parasites transmitted generally increased with donor infection load, more resistant donors transmitted more parasites, as did those with previous transmission experience. Finally, parasites transmitting from experienced donors exhibited lower population growth rates on recipients than those from inexperienced donors. Stage of infection had little effect on transmission parameters. These results suggest that a more holistic consideration of within-host processes will improve our understanding of between-host transmission and hence disease dynamics. This article is part of the themed issue ‘Opening the black box: re-examining the ecology and evolution of parasite transmission’. PMID:28289260

Can value for money be improved by changing the sequence of our donor work-up in the living kidney donor programme?

The aim of the study was to identify procedures of maximum importance for acceptance or rejection of kidney donation from a living donor as well as making the process more cost-effective. We identified all potential living related donors who were examined during the period between January 2002 and December 2006 at our department. The cost in euro (euro) for the programme was estimated using the Danish diagnosis-related group-system (DRG). The donor work-up programme was described. One hundred and thirty-three potential donors were identified; 66 male- and 67 female subjects, median age of 52 years (range 22-69). Sixty-four participants were rejected as donors. Abdominal CT-scan with angiography and urography ruled out 22 of the above 64 potential organ donors; thus, 48% of the volunteers for living kidney donation were unsuited for donation. Abdominal CT-scan with angiography and urography was the procedure identifying most subjects who were unsuited for kidney donation. A rearrangement of the present donor work-up programme could potentially reduce the costs from euro6911 to euro5292 per donor--saving 23% of the costs. By changing the sequence of examinations, it might be possible to cut down on time spent and number of tests needed for approving or rejecting subjects for living kidney donation.

Evaluation Influence: The Evaluation Event and Capital Flow in International Development.

PubMed

Bell, David A

2017-12-01

Assessing program effectiveness in human development is central to informing foreign aid policy-making and organizational learning. Foreign aid effectiveness discussions have increasingly given attention to the devaluing effects of aid flow volatility. This study reveals that the external evaluation event influences actor behavior, serving as a volatility-constraining tool. A case study of a multidonor aid development mechanism served examining the influence of an evaluation event when considering anticipatory effects. The qualitative component used text and focus group data combined with individual interview data (organizations n = 10, including 26 individuals). Quantitative data included financial information on all 75 capital investments. The integrated theory of influence and model of alternative mechanisms used these components to identify the linkage between the evaluation event and capital flow volatility. Aid approved in the year of the midterm evaluation was disbursed by the mechanism with low capital volatility. Anticipating the evaluation event influenced behavior resulting in an empirical record that program outcomes were enhanced and the mechanism was an improved organization. Formative evaluations in a development program can trigger activity as an interim process. That activity provides for a more robust assessment of ultimate consequence of interest. Anticipating an evaluation can stimulate donor reality testing. The findings inform and strengthen future research on the influence of anticipating an evaluation. Closely examining activities before, during, and shortly after the evaluation event can aid development of other systematic methods to improve understanding this phenomenon, as well as improve donor effectiveness strategies.

Financial constraints lead to innovation by IPPF.

PubMed

1998-07-01

In this interview, the International Planned Parenthood Federation's (IPPF) Secretary General, Director of Resource and Program Development, and Special Advisor to the Secretary General commented on IPPF programming innovations being adopted in response to financial constraints. Factors that have led to a reduction in core funding for the IPPF include the fact that other nongovernmental organizations (NGOs) have become more active, that many donor countries have decentralized their funding mechanisms to the country level, and that overall overseas development assistance is being decreased, despite promises made at the 1994 International Conference on Population and Development (ICPD). New funding can be sought from foundations, from the private sector, and by successfully competing with other organizations for funds available from donor countries. Transferring skills to local Family Planning Associations (FPAs) also helps these groups develop their own resource base. The ICPD marked the first time that NGOs were considered a legitimate part of the process of creating a program of action. It will be important for NGOs to demonstrate their ability to translate the goals of the ICPD into action. The IPPF and other NGOs have been successful in helping FPAs expand FP programs to cover reproductive health needs, in dealing with adolescent sexuality, and in enhancing women's empowerment. The IPPF wishes to create stronger alliances between its FPAs and other NGOs dealing with complementary issues and foster a synthesis among the recommendations of the 5 major UN conferences of the 1990s.

Pharmacists' guide to the management of organ donors after brain death.

This article reviews organ donor pathophysiology as it relates to medication use with the goal of maximizing the successful procurement and transplantation of donor organs. The number of patients requiring organ transplantation continues to grow, yet organ donation rates remain flat, making it critical to appropriately manage each organ donor in order to ensure viability of all transplantable organs. The care given to one organ donor is tantamount to the care of several transplant recipients. Aggressive donor management ensures that the largest number of organs can be successfully procured and improves the organs' overall quality. Hospital pharmacists are responsible for processing orders and preparing the medications outlined in donor management algorithms developed by their respective medical systems. It is important that pharmacists understand the details of the medications used in these protocols in order to critically evaluate each medication order and appropriately manage the donor. Typical medications used in organ donors after brain death include medications for blood pressure management and fluid resuscitation, medications necessary for electrolyte management, blood products, vasopressors, hormone replacement therapy, antiinfectives, anticoagulants, paralytics, and organ preservation solutions. It is essential to provide optimal pharmacotherapy for each organ donor to ensure organ recovery and donation. Typical medications used in organ donors include agents for blood pressure management and fluid resuscitation, medications necessary for electrolyte management, blood products, vasopressors, hormone replacement therapy, antiinfectives, anticoagulants, paralytics, and organ preservation solutions.

Several studies have shown a detrimental effect of female donor gender on the survival of solid-organ transplant recipients, including heart, kidney and liver. We evaluated our own experience in heart transplantation in the cyclosporine era, since 1980, to determine the effect of donor gender on survival. We retrospectively reviewed 869 consecutive patients who underwent primary heart transplantation at Stanford University Medical Center between December 1980 and March 2004. Actuarial life-table data were calculated for survival and freedom from rejection and compared between groups. Multivariate Cox proportional hazard analysis was used to identify predictors of reduced long-term survival. One-year mortality in male recipients who received a female donor heart (24%) was higher than in male recipients who received male donor heart (13%) (p = 0.009). Actuarial survival rates for male recipients at 1, 5 and 10 years were 86%, 69% and 50% (with male donor), and 76%, 59% and 45% (with female donor) (p = 0.01), respectively. Donor gender had no effect on long-term survival in male recipients < 45 years of age and female recipients. Female donor gender was identified as an independent risk factor for death by multivariate analysis, with an odds ratio of 2.3 (95% confidence interval 1.5 to 3.4, p < 0.001). In heart transplantation the detrimental effect of female donor gender on recipient survival is significant but limited to male recipients > 45 years of age. These findings should be considered in the process of donor-recipient matching.

In this study we aim to describe the characteristics of non-diabetic organ donors with circulating diabetes-associated autoantibodies collected within the Nordic Network for Islet Transplantation. One thousand and thirty organ donors have been screened in Uppsala for antibodies against glutamic acid decarboxylase (GADA) and islet antigen-2 (IA-2A). The 32 non-diabetic donors that tested positive for GADA (3·3% of all non-diabetic donors) were studied in more detail, together with 32 matched controls. Mean age among the autoantibody-positive donors was 52·6 (range 21–74), family history of type 1 diabetes (T1D) was unknown, and no donor was genetically predisposed for T1D regarding the human leucocyte antigen (HLA) locus. Subjects were analysed for islet cell antibodies (ICA), insulin autoantibodies (IAA) and zinc transporter 8 antibodies (ZnT8A), and pancreas morphology and clinical data were examined. Eight non-diabetic donors tested positive for two antibodies and one donor tested positive for four antibodies. No insulitis or other signs of a diabetic process were found in any of the donors. While inflammatory cells were present in all donors, subjects with high GADA titres had significantly higher CD45 cell numbers in exocrine tissue than controls. The extent of fibrosis was more pronounced in autoantibody-positive donors, even in subjects with lower GADA titres. Notably, it is possible that events not related directly to T1D (e.g. subclinical pancreatitis) may induce autoantibodies in some cases. PMID:26313035

Solid organ transplantation as a treatment for end stage organ failure has been an accepted treatment option for decades. Despite advances in medicine and technology, and increased awareness of organ donation and transplantation, the gap between supply and demand continues to widen. Living donation has been an option that has increased the number of transplants despite the continued shortage of deceased organs. In the early 2000s live donor transplantation reached an all-time high in the United States. As a result, a consensus meeting was convened in 2000 to increase the oversight of living donor transplantation. Both the Centers for Medicare and Medicaid Services and the United Network for Organ Sharing developed regulations that transplant programs performing live donor transplantation. These regulations and guidelines involve the education, evaluation, informed consent process and living donor follow-up care. Two areas in which had significant changes included the psychosocial and the independent living donor advocate (ILDA) evaluation. The purpose of this paper was to outline the current regulations and guidelines associated with the psychosocial and ILDA evaluation as well as provide further recommendations for the administration of a high quality evaluation of living donors. The goals and timing of the evaluation and education of donors; qualifications of the health care providers performing the evaluation; components of the evaluation; education provided to donors; documentation of the evaluation; participation in the selection committee meeting; post-decline and post-donation care of donors is described. Caveats including the paired donor exchange programs and non-directed and directed donation are also considered.

[Lung transplantation: supply and demand in France].

Stern, M; Souilamas, R; Tixier, D; Mal, H

2008-10-01

For a decade lung transplantation has suffered from a lack of donor organs which aroused a national debate and led to planned action in collaboration with The French National Agency for Transplantation. Analysis of the stages of the process from potential donor to lung transplantation identified lung procurement as the main priority. An increase in the number of potential lung donors and revision of the acceptance criteria led to a doubling of the annual rate of lung transplantation in less than two years. In the near future we may solve the problem of donor family refusals and establish scientifically based criteria for lung acceptance to increase the rate of lung transplantation. Transplantation from non heart-beating donors and the reconditioning of ex vivo non acceptable lungs might supply additional organs to fulfill demand in the long term. The rate of lung transplantation activity in France doubled as the result of a dramatic increase of donor lung proposals. The current improvement in the results of lung transplantation might create new demands and generate future difficulties in the supply of donor lungs. New approaches, such as transplantation from non heart-beating donors and reconditioning ex vivo non acceptable lungs, should be examined in the near future.

Socioeconomic disadvantage has been linked to reduced access to kidney transplantation. To understand and address potential barriers to transplantation, we used the Australia and New Zealand Dialysis and Transplant Registry and examined primary kidney-only transplantation among adult non-Indigenous patients who commenced chronic renal replacement therapy in Australia during 2000-2010. Socioeconomic status was derived from residential postcodes using standard indices. Among the 21,190 patients who commenced renal replacement therapy, 4105 received a kidney transplant (2058 from living donors (660 preemptive) or 2047 from deceased donors) by the end of 2010. Compared with the most socioeconomic disadvantaged quartile, patients from the most advantaged quartile were more likely to receive a preemptive transplant (relative rate 1.93), and more likely to receive a living-donor kidney (adjusted subhazard ratio 1.34) after commencing dialysis. Socioeconomic status was not associated with deceased-donor transplantation. Thus, the association between socioeconomic status and living- but not deceased-donor transplantation suggests that potential donors (rather than recipients) from disadvantaged areas may face barriers to donation. Although the deceased-donor organ allocation process appears essentially equitable, it differs between Australian states.

Task shifting is a common strategy to deliver antiretroviral therapy (ART) in resource-limited settings and is safe and effective if implemented appropriately. Consensus among stakeholders is necessary to formulate clear national policies that maintain high-quality care. We sought to understand key stakeholders' opinions regarding task shifting of HIV care in Mozambique and to characterize which specific tasks stakeholders considered appropriate for specific cadres of health workers. National and provincial Ministry of Health leaders, representatives from donor and non-governmental organizations (NGOs), and clinicians providing HIV care were intentionally selected to represent diverse viewpoints. Using open- and closed-ended questions, interviewees were asked about their general support of task shifting, its potential advantages and disadvantages, and whether each of seven cadres of non-physician health workers should perform each of eight tasks related to ART provision. Responses were tallied overall and stratified by current job category. Interviews were conducted between November 2007 and June 2008. Of 62 stakeholders interviewed, 44% held leadership positions in the Ministry of Health, 44% were clinicians providing HIV care, and 13% were donors or employed by NGOs; 89% held a medical degree. Stakeholders were highly supportive of physician assistants performing simple ART-related tasks and unanimous in opposing community health workers providing any ART-related services. The most commonly cited motives to implement task shifting were to increase ART access, decrease physician workload, and decrease patient wait time, whereas chief concerns included reduced quality of care and poor training and supervision. Support for task shifting was higher among clinicians than policy and programme leaders for three specific task/cadre combinations: general mid-level nurses to initiate ART in adults (supported by 75% of clinicians vs. 41% of non-clinicians) and in pregnant women (75% vs. 34%, respectively) and physician assistants to change ART regimens in adults (43% vs. 24%, respectively). Stakeholders agreed on some ART-related task delegation to lower health worker cadres. Clinicians were more likely to support task shifting than policy and programme leaders, perhaps motivated by their front-line experiences. Harmonizing policy and programme managers' views with those of clinicians will be important to formulate and implement clear policy.

From Dark to Light to Fluorescence Resonance Energy Transfer (FRET): Polarity-Sensitive Aggregation-Induced Emission (AIE)-Active Tetraphenylethene-Fused BODIPY Dyes with a Very Large Pseudo-Stokes Shift.

The work presented herein is devoted to the fabrication of large Stokes shift dyes in both organic and aqueous media by combining dark resonance energy transfer (DRET) and fluorescence resonance energy transfer (FRET) in one donor-acceptor system. In this respect, a series of donor-acceptor architectures of 4,4-difluoro-4-bora-3a,4a-diaza-s-indacene (BODIPY) dyes substituted by one, two, or three tetraphenylethene (TPE) luminogens were designed and synthesised. The photophysical properties of these three chromophore systems were studied to provide insight into the nature of donor-acceptor interactions in both THF and aqueous media. Because the generation of emissive TPE donor(s) is strongly polarity dependent, due to its aggregation-induced emission (AIE) feature, one might expect the formation of appreciable fluorescence emission intensity with a very large pseudo-Stokes shift in aqueous media when considering FRET process. Interestingly, similar results were also recorded in THF for the chromophore systems, although the TPE fragment(s) of the dyes are non-emissive. The explanation for this photophysical behaviour lies in the DRET. This is the first report on combining two energy-transfer processes, namely, FRET and DRET, in one polarity-sensitive donor-acceptor pair system. The accuracy of the dark-emissive donor property of the TPE luminogen is also presented for the first time as a new feature for AIE phenomena. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

All-electric control of donor nuclear spin qubits in silicon

The electronic and nuclear spin degrees of freedom of donor impurities in silicon form ultra-coherent two-level systems that are potentially useful for applications in quantum information and are intrinsically compatible with industrial semiconductor processing. However, because of their smaller gyromagnetic ratios, nuclear spins are more difficult to manipulate than electron spins and are often considered too slow for quantum information processing. Moreover, although alternating current magnetic fields are the most natural choice to drive spin transitions and implement quantum gates, they are difficult to confine spatially to the level of a single donor, thus requiring alternative approaches. In recent years, schemes for all-electrical control of donor spin qubits have been proposed but no experimental demonstrations have been reported yet. Here, we demonstrate a scalable all-electric method for controlling neutral 31P and 75As donor nuclear spins in silicon. Using coplanar photonic bandgap resonators, we drive Rabi oscillations on nuclear spins exclusively using electric fields by employing the donor-bound electron as a quantum transducer, much in the spirit of recent works with single-molecule magnets. The electric field confinement leads to major advantages such as low power requirements, higher qubit densities and faster gate times. Additionally, this approach makes it possible to drive nuclear spin qubits either at their resonance frequency or at its first subharmonic, thus reducing device bandwidth requirements. Double quantum transitions can be driven as well, providing easy access to the full computational manifold of our system and making it convenient to implement nuclear spin-based qudits using 75As donors.

The purpose of the study was to examine the loss and grief experiences of patients waiting for and living with new hearts. There is much scholarship on loss and grief. Less attention has been paid to these issues in clinical transplantation, and even less on the patient experience. Part of a qualitative inquiry oriented to the work of Merleau-Ponty, a secondary analysis was carried out on audiovisual data from interviews with thirty participants. Patients experience loss and three forms of grief. Pre-transplant patients waiting for transplant experience loss and anticipatory grief related to their own death and the future death of their donor. Transplanted patients experience long-lasting complicated grief with respect to the donor and disenfranchised grief which may not be sanctioned. Loss as well as anticipatory, complicated and disenfranchised grief may have been inadvertently disregarded or downplayed. More research and attention is needed. Copyright © 2016 Elsevier Inc.

2005-01-01

The Family Communication Coordinator (FCC) Protocol was implemented to provide early family intervention and to facilitate effective communications during potential organ donation cases. Previous studies found the Protocol associated with improved donor outcome measures and with reduced role stress for ICU nurses caring for potential donors. The present study examines the impact of the Protocol on the perceived role stress of hospital chaplains serving as FCCs. All hospital chaplains serving as FCCs at an academic teaching hospital were surveyed. Their perceptions of job dimensions, role stress, job satisfaction, and commitment were measured; interviews and secondary data supplemented the surveys. The findings demonstrate that the FCC Protocol is associated with improved role stress, specifically role ambiguity and role conflict, among hospital chaplains serving as FCCs. Additionally, the findings suggest that satisfaction with the Protocol may be associated with experience with the Protocol.

Malaria is a principal cause of mortality in Africa and represents a major blood-borne disease. The studies made on the continent show that transfusion-associated malaria is highly prevalent in blood donors groups and that some risk factors and clinical manifestations are frequently observed. The disease is mostly asymptomatic and the signs are mild, which reduces significantly an efficient selection of the blood donors during the predonation interview and a secure supply of blood products. Furthermore, the lack of appropriate screening assays of the malaria in blood banks on the continent limit the diagnosis of the disease and hamper the blood safety. However, the prevention of transfusion-associated malaria is a frequently asked question. The destruction of the parasite in the blood bag and the recipient anti-malarial prophylaxis are the described possibilities, added to local programs against the vectors of the disease.

The study aims at discussing the significations apprehended by the non-blood donators, considering the context and the consequences of the acting of the nurse in hemotherapy. It is a qualitative approach, with theoretical frame of Symbolic Interactionism and Grounded Theory method. The data production was carried out by intensive interview with subjects of three sample groups of a University Hospital of Rio de Janeiro City. The phenomenon originated two analysis categories: "Perceiving the blood matter" and "Reflecting about the blood donation campaigns". It was observed that the environment of the donor is not composed by contact with the other and the information that it can achieve, including the media. These were the main basis for the knowledge of blood donation according to their beliefs, culture and values. Therefore, all these aspects must be considered by the nurse acting on donors capture.

In 2000, a referral hospital in the Gambia accepted a donation of oxygen concentrators to help maintain oxygen supplies. The concentrators broke down and were put into storage. A case study was done to find the reasons for the problem and to draw lessons to help improve both oxygen supplies and the success of future equipment donations. A technical assessment of the concentrators was carried out by a biomedical engineer with relevant expertise. Semi-structured interviews were undertaken with key informants, and content analysis and inductive approaches were applied to construct the history of the episode and the reasons for the failure. Interviews confirmed the importance of technical problems with the equipment. They also revealed that the donation process was flawed, and that the hospital did not have the expertise to assess or maintain the equipment. Technical assessment showed that all units had the wrong voltage and frequency, leading to overheating and breakdown. Subsequently a hospital donations committee was established to oversee the donations process. On-site biomedical engineering expertise was arranged with a nongovernmental organization (NGO) partner. Appropriate donations of medical equipment, including oxygen concentrators, can be of benefit to hospitals in resource-poor settings, but recipients and donors need to actively manage donations to ensure that the donations are beneficial. Success requires planning, technical expertise and local participation. Partners with relevant skills and resources may also be needed. In 2002, WHO produced guidelines for medical equipment donations, which address problems that might be encountered. These guidelines should be publicized and used.

Groundwater contamination by heavy metals is a critical environmental problem for which in situ remediation is frequently the only viable treatment option. For such interventions, a multi-dimensional reactive transport model of relevant biogeochemical processes is invaluable. To this end, we developed a model, chrotran, for in situ treatment, which includes full dynamics for five species: a heavy metal to be remediated, an electron donor, biomass, a nontoxic conservative bio-inhibitor, and a biocide. Direct abiotic reduction by donor-metal interaction as well as donor-driven biomass growth and bio-reduction are modeled, along with crucial processes such as donor sorption, bio-fouling, and biomass death. Our software implementation handles heterogeneous flow fields, as well as arbitrarily many chemical species and amendment injection points, and features full coupling between flow and reactive transport. We describe installation and usage and present two example simulations demonstrating its unique capabilities. One simulation suggests an unorthodox approach to remediation of Cr(VI) contamination.

The incorporation of multiple donors into the bulk-heterojunction layer of organic polymer solar cells (PSCs) has been demonstrated as a practical and elegant strategy to improve photovoltaics performance. However, it is challenging to successfully design and blend multiple donors, while minimizing unfavorable interactions (e.g., morphological traps, recombination centers, etc.). Here, a new Förster resonance energy transfer-based design is shown utilizing the synergistic nature of three light active donors (two small molecules and a high-performance donor–acceptor polymer) with a fullerene acceptor to create highly efficient quaternary PSCs with power conversion efficiencies (PCEs) of up to 10.7%. Within this quaternary architecture, itmore » is revealed that the addition of small molecules in low concentrations broadens the absorption bandwidth, induces cocrystalline molecular conformations, and promotes rapid (picosecond) energy transfer processes. Finally, these results provide guidance for the design of multiple-donor systems using simple processing techniques to realize single-junction PSC designs with unprecedented PCEs.« less

NHSBT Tissue Services issues bone to surgeons in the UK in two formats, fresh-frozen unprocessed bone from living donors and processed bone from deceased donors. Processed bone may be frozen or freeze dried and all processed bone is currently subjected to a washing protocol to remove blood and bone marrow. In this study we have improved the current bone washing protocol for cancellous bone and assessed the success of the protocol by measuring the removal of the bone marrow components: soluble protein, DNA and haemoglobin at each step in the process, and residual components in the bone at the end of the process. The bone washing protocol is a combination of sonication, warm water washes, centrifugation and chemical (ethanol and hydrogen peroxide) treatments. We report that the bone washing protocol is capable of removing up to 99.85 % soluble protein, 99.95 % DNA and 100 % of haemoglobin from bone. The new bone washing protocol does not render any bone cytotoxic as shown by contact cytotoxicity assays. No microbiological cell growth was detected in any of the wash steps. This process is now in use for processed cancellous bone issued by NHSBT.

The role of policy actors and contextual factors in policy agenda setting and formulation: maternal fee exemption policies in Ghana over four and a half decades.

Development of health policy is a complex process that does not necessarily follow a particular format and a predictable trajectory. Therefore, agenda setting and selecting of alternatives are critical processes of policy development and can give insights into how and why policies are made. Understanding why some policy issues remain and are maintained whiles others drop off the agenda is an important enquiry. This paper aims to advance understanding of health policy agenda setting and formulation in Ghana, a lower middle-income country, by exploring how and why the maternal (antenatal, delivery and postnatal) fee exemption policy agenda in the health sector has been maintained over the four and half decades since a 'free antenatal care in government facilities' policy was first introduced in October 1963. A mix of historical and contemporary qualitative case studies of nine policy agenda setting and formulation processes was used. Data collection methods involved reviews of archival materials, contemporary records, media content, in-depth interviews, and participant observation. Data was analysed drawing on a combination of policy analysis theories and frameworks. Contextual factors, acting in an interrelating manner, shaped how policy actors acted in a timely manner and closely linked policy content to the intended agenda. Contextual factors that served as bases for the policymaking process were: political ideology, economic crisis, data about health outcomes, historical events, social unrest, change in government, election year, austerity measures, and international agendas. Nkrumah's socialist ideology first set the agenda for free antenatal service in 1963. This policy trajectory taken in 1963 was not reversed by subsequent policy actors because contextual factors and policy actors created a network of influence to maintain this issue on the agenda. Politicians over the years participated in the process to direct and approve the agenda. Donors increasingly gained agenda access within the Ghanaian health sector as they used financial support as leverage. Influencers of policy agenda setting must recognise that the process is complex and intertwined with a mix of political, evidence-based, finance-based, path-dependent, and donor-driven processes. Therefore, influencers need to pay attention to context and policy actors in any strategy.

The Renal Unit of Obafemi Awolowo University Teaching Hospital Ile-Ife in Southwest Nigeria intends commencing a kidney transplantation program. This cross-sectional study aimed at examining the willingness of Nigerians to be living-related kidney donors. Three hundred and sixteen Nigerians (96 first-degree relatives of end-stage renal disease patients, 69 rural dwellers and 151 health workers) were interviewed regarding their willingness to donate kidneys using an interview schedule designed to elicit socio-demographic information, knowledge about kidney transplantation and attitude toward kidney donation. Sixty-two percent of health workers, 52.1% of the patients' relatives and 27.1% of rural dwellers expressed willingness to donate. Higher proportions of health workers and patients' relatives--compared with the rural dwellers--were willing to donate a kidney to their children, full-siblings and parents (P<0.05). The level of awareness about kidney transplantation was highest among health workers and least among rural dwellers (P<0.001). Altruism was the primary motivation for those willing to donate a kidney. The most important reason for refusal to donate was fear of adverse health consequences. Among the rural dwellers, never-married persons were more willing than the married to donate (P<0.05). Programs aimed at increasing awareness about the safety of kidney donation, reducing adverse beliefs about kidney donation, and encouraging altruistic tendencies will increase the availability of kidney donors.

The Retrovirus Epidemiology Donor Study (REDS), conducted from 1989 to 2001, and the REDS-II, conducted from 2004 to 2012, were National Heart, Lung, and Blood Institute-funded, multicenter programs focused on improving blood safety and availability in the United States. The REDS-II also included international study sites in Brazil and China. The 3 major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as xenotropic murine leukemia virus-related virus. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of human immunodeficiency virus, human T-lymphotropic virus 1/2, hepatitis C virus, hepatitis B virus, West Nile virus, cytomegalovirus, human herpesvirus 8, parvovirus B19, malaria, Creutzfeldt-Jakob disease, influenza, and Trypanosoma cruzi infections. Other analyses have characterized blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors' perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, 2 large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these 2 REDS programs. In 2011, a new 7-year program, the Recipient Epidemiology and Donor Evaluation Study-III, was launched. The Recipient Epidemiology and Donor Evaluation Study-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting and adds a third country, South Africa, to the international program.

This feature has been investigated using the rate equation modeling and a methodology for the quantitative estimation of interaction parameters is presented. Moreover, the overall consequences of electron transfer and energy transfer process on donor-acceptor luminescence behavior, quantum efficiency, and donor luminescence decay kinetics are discussed in borate glass host.more » The results in this study propose a straight forward approach to distinguish the electron transfer and energy transfer processes between lanthanide ions in dielectric hosts, which is highly advantageous in view of the recent developments on lanthanide doped materials for spectral conversion, persistent luminescence, and related applications.« less

Donor-derived infections in solid organ transplant patients: toward a holistic approach.

Solid organ demand far exceeds organ supply. Strategies to increase the donor pool include the liberalization of selection criteria without increasing the risk of unexpected donor-derived infection (DDI), a rare complication of transplantation carrying high morbidity and mortality. We review the challenging aspects in the prevention of DDI, focusing on the complexities of data sharing and efficient communication and the role infectious diseases specialists play in the process. Advances in donor screening, transmission recognition and reporting allow for a better estimation of the risk of DDI. However, there is great variability in the frequency and methods with which organ procurement organizations report transmission events.Moreover, the Scientific Registry of Transplant Recipients provides limited donor and recipient outcome infectious diseases related data. Infectious disease contribution to the allocation process has been found to improve organ donation efficiency and communication between involved parties. Although communication gaps are strongly associated with infection transmission (relative risk 2.36%, confidence interval 1.48-3.78), effective communication minimizes or prevents infection in transplant recipients (X(1) 13.13, P = 0.0003). Prospective research is still required to define optimal screening protocols and further prevent transmission of infection. A holistic approach is likely to result in enhanced transplantation safety. Toward this goal, development of standards of investigation; improvement in reporting and data sharing; and strategies ensuring coordinated and rapid communication among parties involved in the allocation process need to be pursued.

Understanding how organ donors' families recover from their grief can help organ procurement organizations improve consent rates and increase the number of deceased donor organs available for transplant. To determine what helps the loved ones of deceased organ donors heal from their grief and loss, and to better understand families' needs during the consent process as a way of improving overall consent rates for organ donation. Written survey of all organ and tissue donors' families in the San Diego and Imperial County (California) service area during 2006 and 2007. Responses to the 20-question survey addressing factors that help healing from grief, as well as contextual information about the families' experience at the hospital and the consent process. Most respondents (84%) indicated that family support was the most helpful thing in dealing with their grief, followed by the support of friends (74%) and religious and cultural beliefs (37%). Most (75%) indicated that they agreed to donation so that something positive could result from their loss. Most respondents (93%) felt that they were given enough information to make an informed decision about donation, and 6% indicated that the donation process interfered with funeral or memorial arrangements. More than 95% understood that their loved one had died before they were approached for consent. Consistent with previous studies, 12% said they still had unanswered questions about aspects of donation, and 15% of respondents indicated that the discussion about organ donation added more emotional stress to their overall experience.

A new method is proposed for a precise planning of autologous bone grafts in cranio- and maxillofacial surgery. In patients with defects of the facial skeleton, autologous bone transplants can be harvested from various donor sites in the body. The preselection of a donor site depends i.a. on the morphological fit of the available bone mass and the shape of the part that is to be transplanted. A thorough planning and simulation of the surgical intervention based on 3D CT studies leads to a geometrical description and the volumetric characterization of the bone part to be resected and transplanted. Both, an optimal fit and a minimal lesion of the donor site are guidelines in this process. We use surface similarity and voxel similarity measures in order to select the optimal donor region for an individually designed transplant.

The Task Force on Organ Transplantation (DHHS,1986) addressed the issue of increasing organ donation. The Report of the Task Force recommended that "educational efforts aimed at increasing organ donation among minority populations be developed and implemented, so that the donor population will more closely reflect the ethnicity of potential transplant recipients, in order to gain the advantage of improved donor and recipient immunologic matching (DHHS,1986). Donor rates for minorities has increased as follows: 16% in 1988 to 23% in 1995 among cadaveric donors and 24% in 1988 to 28% in 1995 among living donors. The improvement in donor rates among minorities may positively affect the transplantation success rate experienced by organ recipients of the same race. Strategies must be implemented that will increase the effectiveness and frequency of communication between minority patients and the medical community. An increase in the effectiveness of communication between potential minority donor families and the health care community will contribute to the process of Consciousness Raising as discussed by Prochasksa. The result of increased awareness of the organ donation and transplantation process may have a favorable impact on organ donation. The media has, through public service announcements, paid advertising and entertainment programming, attempted to promote discussion of organ donation in the community and within families. Johnson et al. discussed Mexican-American and Anglo-American Attitudes Toward Organ Donation. The primary impediment contributing to the disparity of consent rates between Mexican-American and Anglo-American population occurs with regard to the donation of organs of relatives. Johnson stated that this impediment to organ donation can be effectively addressed by promoting family discussion. Communication within families will inform surviving next of kin of the desire of the deceased to be an organ donor and hence improve the likelihood of the donor family consenting to organ donation (Johnson et al., 1988). The promotion of communication within families must continue to be a goal of the transplant community regardless of race/ethnicity. Despite the efforts of the government, the transplant community, the media and the corporate sector to address the critical shortage of donors in the United States, the reality is that no community has the supply of donor organs suitable to meet the need.

The impact of dopant atoms in transistor functionality has significantly changed over the past few decades. In downscaled transistors, discrete dopants with uncontrolled positions and number induce fluctuations in device operation. On the other hand, by gaining access to tunneling through individual dopants, a new type of devices is developed: dopant-atom-based transistors. So far, most studies report transport through dopants randomly located in the channel. However, for practical applications, it is critical to control the location of the donors with simple techniques. Here, we fabricate silicon transistors with selectively nanoscale-doped channels using nano-lithography and thermal-diffusion doping processes. Coupled phosphorus donors form a quantum dot with the ground state split into a number of levels practically equal to the number of coupled donors, when the number of donors is small. Tunneling-transport spectroscopy reveals fine features which can be correlated with the different numbers of donors inside the quantum dot, as also suggested by first-principles simulation results.

The use of human organs and tissues for transplantation in Australia has increased significantly over the past 30 years. In 1997, the Australian Coordinating Committee on Organ Registries and Donation (ACCORD) reported a total number of 190 organ donors, 636 corneal donors and 1509 bone donors Australia wide. Of the 1509 bone donations, 143 came from cadaveric sources and 1366 were made by living donors. Bone transplantation is not as widely recognised as solid organ or corneal transplantation. Due to improved technology and surgical skills, the demand for bone transplantation has increased markedly. This Clinical Update will provide an overview of the physiological aspects of bone transplantation and explore bone banking, a key step in the complex and critical process of bone transplantation.

Background In Brazil little is known about adverse reactions during donation and the donor characteristics that may be associated with such events. Donors are offered snacks and fluids prior to donating and are required to consume a light meal after donation. For these reasons the frequency of reactions may be different than those observed in other countries. Methods A cross-sectional study was conducted of eligible whole blood donors at three large blood centers located in Brazil between July 2007 and December 2009. Vasovagal reactions (VVRs) along with donor demographic and biometric data were collected. Reactions were defined as any presyncopal or syncopal event during the donation process. Multivariable logistic regression was performed to identify predictors of VVRs. Results Of 724,861 donor presentations, 16,129 (2.2%) VVRs were recorded. Rates varied substantially between the three centers: 53, 290 and 381 per 10,000 donations in Recife, São Paulo and Belo Horizonte, respectively. Although the reaction rates varied, the donor characteristics associated with VVRs were similar [younger age (18–29), replacement donors, first time donors, low estimated blood volume (EBV)]. In multivariable analysis controlling for differences between the donor populations in each city younger age, first-time donor status and lower EBV were the factors most associated with reactions. Conclusion Factors associated with VVRs in other locations are also evident in Brazil. The difference in VVR rates between the three centers might be due to different procedures for identifying and reporting the reactions. Potential interventions to reduce the risk of reactions in Brazil should be considered. PMID:22073941

The Netherlands was one of the first countries in Europe to stimulate controlled donation after circulatory death (cDCD) at a national level in addition to donation after brain death (DBD). With this program the number of organ transplants increased, but it also proved to have challenges as will be shown in this 15-year review. Data about deceased organ donation in the Netherlands, from 2000 until 2014, were analysed taking into account the whole donation process from donor referral to the number of organs transplanted. Donor referral increased by 58%, from 213 to 336 donors per year, and the number of organs transplanted rose by 42%. Meanwhile the contribution of cDCD donors increased from 14% in 2000 to 54% in 2014 among all referrals. The organs were transplanted from 92-99% of referred DBD donors, but this percentage was significantly lower for cDCD donors and also decreased from 86% in 2000-2002 to 67% in 2012-2014. In 16% of all referred cDCD donors, organs were not recovered because donors did not die within the expected two-hour time limit after withdrawal of life- upporting treatment. Furthermore, cDCD is more often performed at a higher donor age, which is associated with a lower percentage of transplanted organs. Although cDCD resulted in more transplants, the effort in donor recruitment is considerably higher. Important challenges in cDCD that need further attention are the time limit after withdrawal of life-supporting treatment and donor age, as well as the possibilities to stimulate non-renal transplants including the heart by machine preservation.

Donation after cardiac death (DCD) has increased faster than donation after brain death (DBD) in Australia. However, DBD is the preferred pathway because it provides more organs per donor, the donation process is simpler and transplant outcomes are optimised. To determine if the increase in DCD has reduced the brain-dead donor pool in Australia. Retrospective analysis of records of organ donors (intended and actual) with brain injury as the cause of death from 2001 to 2011 in Australian intensive care units. Change in median ventilation period, over time, before brain-death determination in DBD donors (as DCD increased); a decreased median ventilation period in DBD donors being consistent with the conversion of DBD to DCD. As DCD (n = 311) increased, the median ventilation period in DBD donors (n = 2218) did not fall overall (P = 0.83), in all jurisdictions (P > 0.25) and for all causes of death (P > 0.3). The proportion of patients ventilated for less than 2 days was unchanged over time in both DBD (P = 1) and DCD (P = 0.99). The overall ventilation period in DCD donors (3.8 days; interquartile range [IQR], 2.1-6.3 days), exceeded the ventilation period in DBD donors (1.3 days; IQR, 1.0-2.4 days; P < 0.0001). DCD ventilation period was significantly longer in all jurisdictions, for all causes of death and annually (P < 0.05). In Australia, brain-injured donors appear to be ventilated long enough to allow progression to brain death before proceeding to DCD. Therefore, DCD is unlikely to have reduced the brain-dead donor pool.

The Retrovirus Epidemiology Donor Study (REDS), conducted from 1989–2001, and the Retrovirus Epidemiology Donor Study-II (REDS-II), conducted from 2004–2012, were National Heart Lung and Blood Institute (NHLBI) funded multicenter programs focused on improving blood safety and availability in the United States. REDS-II also included international study sites in Brazil and China. The three major research domains of REDS/REDS-II have been infectious disease risk evaluation, blood donation availability, and blood donor characterization. Both programs have made significant contributions to transfusion medicine research methodology by the use of mathematical modeling, large-scale donor surveys, innovative methods of repository sample storage, and establishing an infrastructure that responded to potential emerging blood safety threats such as XMRV. Blood safety studies have included protocols evaluating epidemiologic and/or laboratory aspects of HIV, HTLV I/II, HCV, HBV, WNV, CMV, HHV-8, B19V, malaria, CJD, influenza, and T. cruzi infections. Other analyses have characterized: blood donor demographics, motivations to donate, factors influencing donor return, behavioral risk factors, donors’ perception of the blood donation screening process, and aspects of donor deferral. In REDS-II, two large-scale blood donor protocols examined iron deficiency in donors and the prevalence of leukocyte antibodies. This review describes the major study results from over 150 peer-reviewed articles published by these two REDS programs. In 2011, a new seven year program, the Recipient Epidemiology and Donor Evaluation Study-III (REDS-III), was launched. REDS-III expands beyond donor-based research to include studies of blood transfusion recipients in the hospital setting, and adds a third country, South Africa, to the international program.

The incidence of morbidity and mortality after living donor liver transplantation (LDLT) is not well understood because reporting is not standardized and relies on single-center reports. Aborted hepatectomies (AHs) and potentially life-threatening near-miss events (during which a donor's life may be in danger but after which there are no long-term sequelae) are rarely reported. We conducted a worldwide survey of programs performing LDLT to determine the incidence of these events. A survey instrument was sent to 148 programs performing LDLT. The programs were asked to provide donor demographics, case volumes, and information about graft types, operative morbidity and mortality, near-miss events, and AHs. Seventy-one programs (48%), which performed donor hepatectomy 11,553 times and represented 21 countries, completed the survey. The average donor morbidity rate was 24%, with 5 donors (0.04%) requiring transplantation. The donor mortality rate was 0.2% (23/11,553), with the majority of deaths occurring within 60 days, and all but 4 deaths were related to the donation surgery. The incidences of near-miss events and AH were 1.1% and 1.2%, respectively. Program experience did not affect the incidence of donor morbidity or mortality, but near-miss events and AH were more likely in low-volume programs (≤50 LDLT procedures). In conclusion, it appears that independently of program experience, there is a consistent donor mortality rate of 0.2% associated with LDLT donor procedures, yet increased experience is associated with lower rates of AH and near-miss events. Potentially life-threatening near-miss events and AH are underappreciated complications that must be discussed as part of the informed consent process with any potential living liver donor.

Skin allografts from cadaver donors are an important resource for treating extensive burns, slow-healing wounds and chronic ulcers. A high level of cell viability of cryopreserved allografts is often required, especially in burn surgery, in Italy. Thus, we aimed to determine which conditions enable procurement of highly viable skin in our Regional Skin Bank of Siena. For this purpose, we assessed cell viability of cryopreserved skin allografts procured between 2011 and 2013 from 127 consecutive skin donors, before and after freezing (at day 15, 180, and 365). For each skin donor, we collected data concerning clinical history (age, sex, smoking, phototype, dyslipidemia, diabetes, cause of death), donation process (multi-tissue or multi-organ) and timing of skin procurement (assessment of intervals such as death-harvesting, harvesting-banking, death-banking). All these variables were analysed in the whole case study (127 donors) and in different groups (e.g. multi-organ donors, non refrigerated multi-tissue donors, refrigerated multi-tissue donors) for correlations with cell viability. Our results indicated that cryopreserved skin allografts with higher cell viability were obtained from female, non smoker, heartbeating donors died of cerebral haemorrhage, and were harvested within 2 h of aortic clamping and banked within 12 h of harvesting (13-14 h from clamping). Age, cause of death and dyslipidaemia or diabetes did not appear to influence cell viability. To maintain acceptable cell viability, our skin bank needs to reduce the time interval between harvesting and banking, especially for refrigerated donors.

Marginal kidney donor

Renal transplantation is the treatment of choice for a medically eligible patient with end stage renal disease. The number of renal transplants has increased rapidly over the last two decades. However, the demand for organs has increased even more. This disparity between the availability of organs and waitlisted patients for transplants has forced many transplant centers across the world to use marginal kidneys and donors. We performed a Medline search to establish the current status of marginal kidney donors in the world. Transplant programs using marginal deceased renal grafts is well established. The focus is now on efforts to improve their results. Utilization of non-heart-beating donors is still in a plateau phase and comprises a minor percentage of deceased donations. The main concern is primary non-function of the renal graft apart from legal and ethical issues. Transplants with living donors outnumbered cadaveric transplants at many centers in the last decade. There has been an increased use of marginal living kidney donors with some acceptable medical risks. Our primary concern is the safety of the living donor. There is not enough scientific data available to quantify the risks involved for such donation. The definition of marginal living donor is still not clear and there are no uniform recommendations. The decision must be tailored to each donor who in turn should be actively involved at all levels of the decision-making process. In the current circumstances, our responsibility is very crucial in making decisions for either accepting or rejecting a marginal living donor. PMID:19718332

Donations in Greece are insufficient to cover the high transfusion needs arising from large numbers of thalassaemia and sickle cell anaemia patients and the implementation of new surgical techniques. Efforts to achieve self-sufficiency, and to render blood supplies safer and manageable must focus on recruiting and retaining more volunteer donors and on converting the large pool of replacement donors. The aim of the study was to gain insight into public perception regarding the risks of donation and transfusion and to identify the factors that would motivate more people in Greece to regularly donate blood. Questionnaires were distributed to 1600 donors at the blood bank and visitors to hospitals at 11 locations across the country. Data on demographics, donation behaviour, incentives, risk perception and attitudes towards donation and transfusion were analysed separately for volunteer and replacement donors and non-donors. The results showed that women and young people donate the least in Greece. Also, many donors do not donate because they are not reminded to. A small percentage of donors confessed to having concealed part of the truth to background questions. Overall, incentives to donate were considered important and included future availability of blood for self or family, paid leave from work and free blood tests. Recruitment and retention efforts should include better communication with current donors, and raising awareness among eligible donors. Staff should be educated in soliciting information from potential donors, and incentives should be better aligned to avoid conflict with ethical values and ensure honesty in the prescreening process.

Allogeneic hematopoietic stem cell transplantation (SCT) may cure patients with hematologic malignancies, but it carries significant risks. Careful donor selection is an important component of the clinical transplantation decision-making process and includes evaluation of HLA typing and other criteria, the most controversial of which is parity. We examined the effect of donor sex and parity on outcomes of HLA-identical sibling SCT. Because the effect of recipient sex/parity has never been explicitly evaluated, we also analyzed the effect of recipient sex/parity on outcomes of transplantation. We found that (1) parous female donors result in an increased risk of chronic graft-versus-host disease (GVHD) in all recipients, (2) the magnitude of this increased risk is similar in male and female recipients, and (3) nulliparous female donors increase the risk of chronic GVHD in male recipients to a degree comparable to that from parous donors. A decrease in the risk of relapse was not observed, and there was no effect on overall survival, acute GVHD, or transplant-related mortality. Recipient parity had no independent effect on any endpoint. Until the effects of pregnancy on the maternal immune system are better understood, it is appropriate whenever possible to avoid parous female donors and to choose male donors for male recipients in HLA-identical related donor SCT.

Optimal screening and donor management in a public stool bank.

Fecal microbiota transplantation is an effective treatment for recurrent Clostridium difficile infection and is being investigated as a treatment for other microbiota-associated diseases. To facilitate these activities, an international public stool bank has been created, which screens donors and processes stools in a standardized manner. The goal of this research is to use mathematical modeling and analysis to optimize screening and donor management at the stool bank. Compared to the current policy of screening active donors every 60 days before releasing their quarantined stools for sale, costs can be reduced by 10.3 % by increasing the screening frequency to every 36 days. In addition, the stool production rate varies widely across donors, and using donor-specific screening, where higher producers are screened more frequently, also reduces costs, as does introducing an interim (i.e., between consecutive regular tests) stool test for just rotavirus and C. difficile. We also derive a donor release (i.e., into the system) policy that allows the supply to approximately match an exponentially increasing deterministic demand. More frequent screening, interim screening for rotavirus and C. difficile, and donor-specific screening, where higher stool producers are screened more frequently, are all cost-reducing measures. If screening costs decrease in the future (e.g., as a result of bringing screening in house), a bottleneck for implementing some of these recommendations may be the reluctance of donors to undergo serum screening more frequently than monthly.

Understanding what prevents people from ever donating blood, or having donated, what influenced them to stop, are both equally important in devising recruitment strategies. Enlisting new donors and encouraging previous donors to return are vital to increasing collections. Six racially homogeneous focus groups of never donors and lapsed donors were conducted. Both sexes and a range of age groups were represented. The importance of blood donation as a volunteer activity, deterrents, motivations, awareness of need, and effective recruitment messages were topics discussed. Never donors do not see blood donation as an important volunteer activity on par with others like volunteering at hospitals, schools, and support groups. Fear and inconvenience were major barriers to donating. Better education campaigns to allay fears about donating and workplace drives were considered important motivators. Participants were unaware of the need for blood. Media messages that combine safety of the process along with who it benefits were considered most effective. Messages that target the specific needs of minority communities were considered good motivators for their recruitment. Blood collection agencies should increase awareness that blood donation is a worthwhile and important volunteer activity. Another strategy would be to capitalize on the existing perception that donating blood is like donating money or used clothing, by focusing on the concept of giving something tangible. Along with providing convenient opportunities to donate, blood centers need to effectively convey the need for blood and allay fears about the donation process to increase the current donor pool.

The objective was to determine if a free, voluntary diabetes screening program as a part of the blood donation process might be cost-effective. During the first 6 months of the program, 26,415 donors were screened using a single random plasma glucose (RPG) level. All donors were asked to eat before donation. Low-, moderate-, and high-risk groups were formed based on RPG levels (<140, 140-200, and >200 mg/dL). Contact with a telephone questionnaire was made with 139 of 178 (78%) of the persons in the high-risk group with 33 new cases of diabetes diagnosed by the donor's physician and 26 donors indicating that they were not diagnosed with diabetes. Sex- and age-matched donors in the low- and moderate-risk groups were contacted and administered the same questionnaire. The three risk groups were similar, except for body mass index (28.1 ± 5.4 kg/m2 vs. 29.9 ± 5.5 kg/m2 vs. 32.7 ± 5.6 kg/m2 , p < 0.001). The discriminative effectiveness of screening was evaluated by the area under the receiver operating characteristics (AROC) curve. The AROC curve was 0.950 (95% confidence interval, 0.920-0.979) for the identification of diabetes. Using a RPG cutoff of 200 mg/dL, sensitivity was 100%, specificity was 82%, and positive predictive value was 56%. Cost analyses showed that the mean cost to screen, per donor, was less than $1. Cost per case identified was estimated to be less than $500 for a RPG cutoff of 200 mg/dL. Screening during the blood donation process appears to be accurate, convenient, and inexpensive. © 2013 American Association of Blood Banks.

The 2017 Kidney Disease: Improving Global Outcomes (KDIGO) Clinical Practice Guideline on the Evaluation and Care of Living Kidney Donors is intended to assist medical professionals who evaluate living kidney donor candidates and provide care before, during and after donation. The guideline development process followed the Grades of Recommendation Assessment, Development, and Evaluation (GRADE) approach and guideline recommendations are based on systematic reviews of relevant studies that included critical appraisal of the quality of the evidence and the strength of recommendations. However, many recommendations, for which there was no evidence or no systematic search for evidence was undertaken by the Evidence Review Team, were issued as ungraded expert opinion recommendations. The guideline work group concluded that a comprehensive approach to risk assessment should replace decisions based on assessments of single risk factors in isolation. Original data analyses were undertaken to produce a "proof-in-concept" risk-prediction model for kidney failure to support a framework for quantitative risk assessment in the donor candidate evaluation and defensible shared decision making. This framework is grounded in the simultaneous consideration of each candidate's profile of demographic and health characteristics. The processes and framework for the donor candidate evaluation are presented, along with recommendations for optimal care before, during, and after donation. Limitations of the evidence are discussed, especially regarding the lack of definitive prospective studies and clinical outcome trials. Suggestions for future research, including the need for continued refinement of long-term risk prediction and novel approaches to estimating donation-attributable risks, are also provided.In citing this document, the following format should be used: Kidney Disease: Improving Global Outcomes (KDIGO) Living Kidney Donor Work Group.

The selection of medium and associated reagents for human mesenchymal stromal cell (hMSC) culture forms an integral part of manufacturing process development and must be suitable for multiple process scales and expansion technologies. In this work, we have expanded BM-hMSCs in fetal bovine serum (FBS)- and human platelet lysate (HPL)-containing media in both a monolayer and a suspension-based microcarrier process. The introduction of HPL into the monolayer process increased the BM-hMSC growth rate at the first experimental passage by 0.049 day and 0.127/day for the two BM-hMSC donors compared with the FBS-based monolayer process. This increase in growth rate in HPL-containing medium was associated with an increase in the inter-donor consistency, with an inter-donor range of 0.406 cumulative population doublings after 18 days compared with 2.013 in FBS-containing medium. Identity and quality characteristics of the BM-hMSCs are also comparable between conditions in terms of colony-forming potential, osteogenic potential and expression of key genes during monolayer and post-harvest from microcarrier expansion. BM-hMSCs cultured on microcarriers in HPL-containing medium demonstrated a reduction in the initial lag phase for both BM-hMSC donors and an increased BM-hMSC yield after 6 days of culture to 1.20 ± 0.17 × 10(5) and 1.02 ± 0.005 × 10(5) cells/mL compared with 0.79 ± 0.05 × 10(5) and 0.36 ± 0.04 × 10(5) cells/mL in FBS-containing medium. This study has demonstrated that HPL, compared with FBS-containing medium, delivers increased growth and comparability across two BM-hMSC donors between monolayer and microcarrier culture, which will have key implications for process transfer during scale-up.

Stimulating microbial reduction of soluble U(VI) to less soluble U(IV) shows promise as an in situ bioremediation strategy for uranium contaminated groundwater, but the optimal electron donors for promoting this process have yet to be identified. The purpose of this study was to better understand how the addition of various electron donors to uranium-contaminated subsurface sediments affected U(VI) reduction and the composition of the microbial community. The simple electron donors, acetate or lactate, or the more complex donors, hydrogen-release compound (HRC) or vegetable oil, were added to the sediments incubated in flow-through columns. The composition of the microbial communities was evaluated with quantitative PCR probing specific 16S rRNA genes and functional genes, phospholipid fatty acid analysis, and clone libraries. All the electron donors promoted U(VI) removal, even though the composition of the microbial communities was different with each donor. In general, the overall biomass, rather than the specific bacterial species, was the factor most related to U(VI) removal. Vegetable oil and HRC were more effective in stimulating U(VI) removal than acetate. These results suggest that the addition of more complex organic electron donors could be an excellent option for in situ bioremediation of uranium-contaminated groundwater.

Although sexual functioning is an important facet of living donor quality of life, it has not received extensive evaluation in this population. Using data from the Adult-to-Adult Living Donor Liver Transplantation Cohort Study, we examined donor sexual functioning across the donation process from the predonation evaluation to 3 months and 1 year postdonation. Donors (n=208) and a comparison group of non-donors (n=155) completed self-reported surveys with specific questions on sexual desire, satisfaction, orgasm, and (for men) erectile function. Across the three time points, donor sexual functioning was lower at the evaluation phase and 3 months postdonation than at one year postdonation. In the early recovery period, abdominal pain was associated with difficulty reaching orgasm (OR = 3.98, 95% CI 1.30–12.16), concerns over appearance with lower sexual desire (OR = 4.14, 95% CI 1.02–16.79), and not feeling back to normal was associated with dissatisfaction with sexual life (OR 3.58, 95% CI 1.43–8.99). Efforts to educate donors before the surgery and prepare them for the early recovery phase may improve recovery and reduce distress regarding sexual functioning. PMID:25779554

Minimally invasive live donor nephrectomy has become a fully implemented and accepted procedure. Donors have to be well educated about all risks and details during the informed consent process. For this to be successful, more information regarding short-term outcome is necessary. A literature search was performed; all studies discussing short-term complications after minimally invasive live donor nephrectomy were included. Outcomes evaluated were intraoperative and postoperative complications, conversions, operative and warm ischemia times, blood loss, length of hospital stay, pain score, convalescence, quality of life, and costs. One hundred ninety articles were included in the systematic review, 41 in the meta-analysis. Conversion rate was 1.1%. Intraoperative complication rate was 2.3%, mainly bleeding (1.5%). Postoperative complications occurred in 7.3% of donors, including infectious complications (2.6%), of which mainly wound infection (1.6%) and bleeding (1.0%). Reported mortality rate was 0.01%. All minimally invasive techniques were comparable with regard to complication or conversion rate. The used techniques for minimally invasive live donor nephrectomy are safe and associated with low complication rates and minimal risk of mortality. These data may be helpful to develop a standardized, donor-tailored informed consent procedure for live donor nephrectomy.

The scarcity of ideal liver grafts for orthotopic liver transplantation (OLT) has led transplant teams to investigate other sources of grafts in order to augment the donor liver pool. One way to get more liver grafts is to use marginal donors, a not well-defined group which includes mainly donors > 60 years, donors with hypernatremia or macrosteatosis > 30%, donors with hepatitis C virus or hepatitis B virus positive serologies, cold ischemia time > 12 h, non-heart-beating donors, and grafts from split-livers or living-related donations. Perhaps the most practical and frequent measure to increase the liver pool, and thus to reduce waiting list mortality, is to use older livers. In the past years the results of OLT with old livers have improved, mainly due to better selection and maintenance of donors, improvements in surgical techniques in donors and recipients, and intra- and post-OLT management. At the present time, sexagenarian livers are generally accepted, but there still exists some controversy regarding the use of septuagenarian and octogenarian liver grafts. The aim of this paper is to briefly review the aging process of the liver and reported experiences using old livers for OLT. Fundamentally, the series of septuagenarian and octogenarian livers will be addressed to see if there is a limit to using these aged grafts.

To evaluate variability in donor semen quality between seven commercial donor sperm banks, within sperm banks, and between intracervical insemination and intrauterine insemination. Prospective, randomized, blind evaluation of commercially available donor semen samples. An academic andrology laboratory. Seventy-five cryopreserved donor semen samples were evaluated. Samples were coded, then blindly evaluated for semen quality. Standard semen quality parameters, including concentration, motility parameters, World Health Organization criteria morphology, and strict criteria morphology. Significant differences were observed between donor semen banks for most semen quality parameters analyzed in intracervical insemination samples. In general, the greatest variability observed between banks was in percentage progressive sperm motility (range, 8.8 +/- 5.8 to 42.4 +/- 5.5) and normal sperm morphology (strict criteria; range, 10.1 +/- 3.3 to 26.6 +/- 4.7). Coefficients of variation within sperm banks were generally high. These data demonstrate the variability of donor semen quality provided by commercial sperm banks, both between banks and within a given bank. No relationship was observed between the size or type of sperm bank and the degree of variability. The data demonstrate the lack of uniformity in the criteria used to screen potential semen donors and emphasize the need for more stringent screening criteria and strict quality control in processing samples.

Ternary organic solar cells (OSCs) are very attractive for further enhancing the power conversion efficiencies (PCEs) of binary ones but still with a single active layer. However, improving the PCEs is still challenging because a ternary cell with one more component is more complicated on phase separation behavior. If the two donors or two acceptors have similar chemical structures, good miscibility can be expected to reduce the try-and-error work. Herein, we report ternary devices based on two small molecule donors with the same backbone but different substituents. Whereas both binary devices show PCEs about 9%, the PCE of the ternary cells is enhanced to 10.17% with improved fill factor and short-circuit current values and external quantum efficiencies almost in the whole absorption wavelength region from 440 to 850 nm. The same backbone enables the donors miscible at molecular level, and the donor with a higher HOMO level plays hole relay process to facilitate the charge transportation in the ternary devices. Since side-chain engineering has been well performed to tune the active materials' energy levels in OSCs, our results suggest that their ternary systems are promising for further improving the binary cells' performance although their absorptions are not complementary.

Donated tissues can save lives of critically burned patients and those needing a heart valve replacement. Tissues enhance the lives of a million recipients annually through transplants of corneas, bones, tendons, and vein grafts. Unfortunately, the need for some tissues exceeds their availability. The goal of the quantitative component of this mixed methods study was to identify the grief, posttraumatic stress, personal growth, and ongoing attachment response of tissue donors' family members during a 2-year period. Simultaneous mixed methods design. The sample for this study consisted of 52 tissue donors' family members, mostly widows (83%). Data were collected for 2 years to test changes in grief, posttraumatic stress, panic behavior, personal growth, and ongoing attachment. The bereaved participants experienced significantly fewer grief reactions, less posttraumatic stress, and greater personal growth. There was no significant difference in the ongoing attachment to their deceased loved ones. The results of this study may reinforce the positive meaning that tissue donors' family members can find in tissue donation. Findings also demonstrate that the bereavement process corroborates contemporary bereavement and attachment theories. Health professionals are encouraged to seek donations with less worry that tissue donors' family members will experience adverse outcomes during bereavement.

In this work, epitaxial GaN with different Mg doping concentration annealed at different temperature is investigated. Through Hall and PL spectra measurement we found that when Mg doping concentration is different, different annealing temperature is needed for obtaining the best p-type conduction of GaN, and this difference comes from the different influence of annealing on compensated donors. For ultra-heavily Mg doped sample, the process of Mg related donors transferring to non-radiative recombination centers is dominated, so the performance of P-GaN deteriorates with temperature increase. But for low Mg doped sample, the process of Mg related donors transfer to non-raditive recombination is weak compare to the Mg acceptor activation, so along the annealing temperature increase the performance GaN gets better.

Low donor content solar cells containing polymeric and non-polymeric donors blended with fullerenes have been reported to give rise to efficient devices. In this letter, we report that a dendrimeric donor can also be used in solution-processed low donor content devices when blended with a fullerene. A third generation dendrimer containing 42 thiophene units (42T) was found to give power conversion efficiencies of up to 3.5% when blended with PC70BM in optimized devices. The best efficiency was measured with 10 mole percent (mol. %) of 42T in PC70BM and X-ray reflectometry showed that the blends were uniform. Importantly, while 42T comprised 10 mol. % of the film, it made up 31% of the film by volume. Finally, it was found that solvent annealing was required to achieve the largest open circuit voltage and highest device efficiencies.

Microbiological contamination of retrieved tissues has become a very important topic and a critical aspect in the safety of allografts. We have analysed contamination in 11,129 tissues with a longitudinal contamination profile for each individual tissue. More specifically, 10,035 musculoskeletal tissues and 1,094 cardiovascular tissues were retrieved from a total of 763 multi-tissue donors, of whom 105 were heart-beating donors as well as organ donors, while the remaining 658 were non-heart beating donors and tissue donors only. All tissues were decontaminated twice, the first time immediately after retrieval and the second time after processing. Each tissue was submitted to microbiological culture three times, i.e., upon retrieval (Time 1), after the first decontamination (Time 2) and after the second decontamination (Time 3). The contamination rate for musculoskeletal tissues was 52%, 16.2% and 0.5% at Time 1, 2 and 3, respectively. The contamination rate for cardiovascular tissues was 84%, 42% and 6%. More than one strain was simultaneously present in 10.8% of musculoskeletal tissues and 44.6% of cardiovascular tissues. Out of 8,560 non-heart-beating donor musculoskeletal tissues, 4,689 (54.8%), 1,383 (16.2%) and 42 (0.5%) were contaminated at Time 1, Time 2 and Time 3, respectively. Out of 1,475 heart-beating donor musculoskeletal tissues, 522 (35.4%) 113 (7.7%) and 2 (0.1%) tissues were found to be contaminated at Time 1, 2 and 3, respectively. Out of 984 non-heart beating donor cardiovascular tissues, 869 (88.3%), 449 (45.6%) and 69 (7%) proved positive at Time 1, 2 and 3 respectively, while 50 (45.5%) and 10 (9.1%) heart-beating donor cardiovascular tissues were contaminated at Time 1 and 2. No tissue was contaminated at Time 3. Based on our methods, the two-step decontamination approach is mandatory in order to drastically reduce the number of tissues found to be positive at the end of the process.

Adolescent-Friendly Health Services (AFHSs) are those that are accessible, acceptable, equitable, appropriate and effective for different youth sub-populations. This study investigated the process through which four clinics in two countries - Peru and Ecuador - introduced, developed and sustained AFHSs. A multiple case study design was chosen, and data from each clinic were collected through document review, observations and informant interviews. National level data were also collected. Data were analysed following thematic analysis. The findings showed that the process of introducing, developing and sustaining AFHSs was long term, and required a creative team effort and collaboration between donors, public institutions and health providers. The motivation and external support was crucial to initiating and sustaining the implementation of AFHSs. Health facilities' transformation into AFHSs was linked to the broader organisation of country health systems, and the evolution of national adolescent health policies. In Peru, the centralised approach to AFHSs introduction facilitated the dissemination of a comprehensive national model to health facilities, but dependency on national directives made it more difficult to systemise them when ideological and organisational changes occurred. In Ecuador, a less centralised approach to introducing AFHSs made for easier integration of the AFHSs model.

In many countries blood donors can exclude their donated blood from being transfused in a confidential unit exclusion (CUE) process. We aimed to identify characteristics which might influence the decision for CUE. In a 3-step approach we first enrolled 29 German blood donation centers in 2005 and addressed how the clarity of different CUE forms applied in these centers was rated by first time blood donors and also assessed three newly designed CUE forms. Second, we performed a survey on the characteristics of the CUE process including 25 centers. Third, we performed an intervention study, in which the CUE form originally applied in the study centre was compared with a newly developed CUE form in a before-after study design with respect to the corresponding CUE rates. (1) Clarity of the CUE forms varied considerably. (2) The CUE rate was higher (P < 0.05) when nurses rather than a physician were involved in informing the donors and when the CUE form was submitted anonymously instead of being handed to a person. (3) Application of the newly designed CUE form which was rated as being very clear resulted in a 31% decrease in the CUE rate. Design of the CUE form and characteristics of the CUE process may considerably influence the CUE rates.

Over a period of 30 months, the Niguarda Ca'Granda Hospital performed 12 living donor liver transplants (LDLT) on adult subjects using the split-liver technique and transplant of the right lobe. The purpose of this work is to evaluate the financial obligation that this technique will bring, the ethical and cultural aspects, and the mortality related to surgery on a healthy donor whose only reward is in the knowledge of having done everything possible for a loved family member. The analysis of the costs of the surgical process takes into account the simultaneous consideration of both types of patients: the donor and the recipient. The diagnostic course is subdivided into seven functional phases of the cost centers, and the transitory sequences of the foreseeable events of the entire process. The method used consists in the appraisal of all the clinical activities in chronological order several the centers of cost. The direct expenses are evaluated according to an analytical method, and the indirect costs has been carried out on the criterion of the activities of support to the process (management of the orders, recording and programming of the activities) and support to the organization (maintenance, management supplying and contests of contract, programming of the business production, management warehouses, supplyings, marketing and relations with the public). The cost of all the patients evaluated that were not able to donate has been added to the direct expenses of 12 donor and 12 recipient patients, in all 30 patients, so as to shift the added expenses only to the donor patient, since these costs are not included in the typical costs of transplantation from a cadaver. The indirect cost calculated for each patient has been added to the direct costs of the donor and recipient patients. The total calculated cost of LDLT is 175, 210.78 Euros. The analysis of the economical obligation that this practice brings is the starting point for an accurate evaluation of all the new technology that, in conjunction with the results of clinical efficacy and efficiency trials, is part of program of a larger scope to fulfil the general social principles of equity and justice.

Social behavior and kin discrimination in a mixed group of cloned and non cloned heifers (Bos taurus).

For more than ten years, reproductive biotechnologies using somatic cell nuclear transfer have made possible the production of cloned animals in various domestic and laboratory species. The influence of the cloning process on offspring characteristics has been studied in various developmental aspects, however, it has not yet been documented in detail for behavioral traits. Behavioral studies of cloned animals have failed to show clear inter-individual differences associated with the cloning process. Preliminary results showed that clones favor each other's company. Preferential social interactions were observed among cloned heifers from the same donor in a mixed herd that also included cloned heifers and control heifers produced by artificial insemination (AI). These results suggest behavioral differences between cloned and non-cloned animals and similarities between clones from the same donor. The aim of the present study was to replicate and to extend these previous results and to study behavioral and cognitive mechanisms of this preferential grouping. We studied a group composed of five cloned heifers derived from the same donor cow, two cloned heifers derived from another donor cow, and AI heifers. Cloned heifers from the same donor were more spatially associated and interacted more between themselves than with heifers derived from another donor or with the AI individuals. This pattern indicates a possible kin discrimination in clones. To study this process, we performed an experiment (using an instrumental conditioning procedure with food reward) of visual discrimination between images of heads of familiar heifers, either related to the subjects or not. The results showed that all subjects (AI and cloned heifers) discriminated between images of familiar cloned heifers produced from the same donor and images of familiar unrelated heifers. Cattle discriminated well between images and used morphological similarities characteristic of cloned related heifers. Our results suggest similar cognitive capacities of kin and non kin discrimination in AI and cloned animals. Kinship may be a common factor in determining the social grouping within a herd.

Organ donation: a significant marketing challenge.

PubMed

Clarke, Roberta N

2007-01-01

Unlike most health care markets, the organ donation market is one where patients are the marketers, prospective donors are the customers, and no payment is allowed in the exchange process. The assumption that altruistic behavior by donors would satisfy the need for organs has proven woefully untrue. As a result, those needing organs have resorted to relying on unwilling or impoverished donors, to having to promote themselves on websites which have achieved success for only small numbers of patients, or to waiting for organs which they may never receive. This remains a still unsolved marketing challenge.

Gigantic photoionization was discovered on GaAs-oxide interfaces leading to the discharge of deep surface states with rates exceeding 1000 times those of photoionization transitions to the conduction band. It exhibits a peak similar to acceptor-donor transitions and is explained as due to energy transfer from photo-excited donor-acceptor pairs to deep surface states. This new process indicates the presence of significant concentrations of shallow donor and acceptor levels not recognized in previous interface models.

Background Self-administered computer-assisted blood donor screening strategies may elicit more accurate responses and improve the screening process. Methods Randomized crossover trial comparing responses to questions on a computerized hand-held tool (HealthQuiz, or HQ), to responses on the standard written instrument (Donor Health Assessment Questionnaire, or DHAQ). Randomly selected donors at 133 blood donation clinics in the area of Hamilton, Canada participated from 1995 to 1996. Donors were randomized to complete either the HQ or the DHAQ first, followed by the other instrument. In addition to responses of 'yes' and 'no' on both questionnaires, the HQ provided a response option of 'not sure'. The primary outcome was the number of additional donors deferred by the HQ. Results A total of 1239 donors participated. Seventy-one potential donors were deferred as a result of responses to the questionnaires; 56.3% (40/71) were deferred by the DHAQ, and an additional 43.7% (31/71) were deferred due to risks identified by the HQ but not by the DHAQ. Fourteen donors self-deferred; 11 indicated on the HQ that they should not donate blood on that day but did not use the confidential self-exclusion option on the DHAQ, and three used the self-exclusion option on the DHAQ but did not indicate that they should not donate blood on the HQ. The HQ identified a blood contact or risk factor for HIV/AIDS or sexually transmitted infection that was not identified by the DHAQ in 0.1% to 2.7% of donors. Conclusion A self-administered computerized questionnaire may increase risk reporting by blood donors. PMID:12191432

Health financing policies in Sub-Saharan Africa: government ownership or donors' influence? A scoping review of policymaking processes.

PubMed

Gautier, Lara; Ridde, Valéry

2017-01-01

The rise on the international scene of advocacy for universal health coverage (UHC) was accompanied by the promotion of a variety of health financing policies. Major donors presented health insurance, user fee exemption, and results-based financing policies as relevant instruments for achieving UHC in Sub-Saharan Africa. The "donor-driven" push for policies aiming at UHC raises concerns about governments' effective buy-in of such policies. Because the latter has implications on the success of such policies, we searched for evidence of government ownership of the policymaking process. We conducted a scoping review of the English and French literature from January 2001 to December 2015 on government ownership of decision-making on policies aiming at UHC in Sub-Saharan Africa. Thirty-five (35) results were retrieved. We extracted, synthesized and analyzed data in order to provide insights on ownership at five stages of the policymaking process: emergence, formulation, funding, implementation, and evaluation. The majority of articles (24/35) showed mixed results (i.e. ownership was identified at one or more levels of policymaking process but not all) in terms of government ownership. Authors of only five papers provided evidence of ownership at all reviewed policymaking stages. When results demonstrated some lack of government ownership at any of the five stages, we noticed that donors did not necessarily play a role: other actors' involvement was contributing to undermining government-owned decision-making, such as the private sector. We also found evidence that both government ownership and donors' influence can successfully coexist. Future research should look beyond indicators of government ownership, by analyzing historical factors behind the imbalance of power between the different actors during policy negotiations. There is a need to investigate how some national actors become policy champions and thereby influence policy formulation. In order to effectively achieve government ownership of financing policies aiming at UHC, we recommend strengthening the State's coordination and domestic funding mobilization roles, together with securing a higher involvement of governmental (both political and technical) actors by donors.

Age Is Relative-Impact of Donor Age on Induced Pluripotent Stem Cell-Derived Cell Functionality.

Induced pluripotent stem cells (iPSCs) avoid many of the restrictions that hamper the application of human embryonic stem cells: limited availability of source material due to legal restrictions in some countries, immunogenic rejection and ethical concerns. Also, the donor's clinical phenotype is often known when working with iPSCs. Therefore, iPSCs seem ideal to tackle the two biggest tasks of regenerative medicine: degenerative diseases with genetic cause (e.g., Duchenne's muscular dystrophy) and organ replacement in age-related diseases (e.g., end-stage heart or renal failure), especially in combination with recently developed gene-editing tools. In the setting of autologous transplantation in elderly patients, donor age becomes a potentially relevant factor that needs to be assessed. Here, we review and critically discuss available data pertinent to the questions: How does donor age influence the reprogramming process and iPSC functionality? Would it even be possible to reprogram senescent somatic cells? How does donor age affect iPSC differentiation into specialised cells and their functionality? We also identify research needs, which might help resolve current unknowns. Until recently, most hallmarks of ageing were attributed to an accumulation of DNA damage over time, and it was thus expected that DNA damage from a somatic cell would accumulate in iPSCs and the cells derived from them. In line with this, a decreased lifespan of cloned organisms compared with the donor was also observed in early cloning experiments. Therefore, it was questioned for a time whether iPSC derived from an old individual's somatic cells would suffer from early senescence and, thus, may not be a viable option either for disease modelling nor future clinical applications. Instead, typical signs of cellular ageing are reverted in the process of iPSC reprogramming, and iPSCs from older donors do not show diminished differentiation potential nor do iPSC-derived cells from older donors suffer early senescence or show functional impairments when compared with those from younger donors. Thus, the data would suggest that donor age does not limit iPSC application for modelling genetic diseases nor regenerative therapies. However, open questions remain, e.g., regarding the potential tumourigenicity of iPSC-derived cells and the impact of epigenetic pattern retention.

Electrical Manipulation of Donor Spin Qubits in Silicon and Germanium

NASA Astrophysics Data System (ADS)

Sigillito, Anthony James

Many proposals for quantum information devices rely on electronic or nuclear spins in semiconductors because of their long coherence times and compatibility with industrial fabrication processes. One of the most notable qubits is the electron spin bound to phosphorus donors in silicon, which offers coherence times exceeding seconds at low temperatures. These donors are naturally isolated from their environments to the extent that silicon has been coined a "semiconductor vacuum". While this makes for ultra-coherent qubits, it is difficult to couple two remote donors so quantum information proposals rely on high density arrays of qubits. Here, single qubit addressability becomes an issue. Ideally one would address individual qubits using electric fields which can be easily confined. Typically these schemes rely on tuning a donor spin qubit onto and off of resonance with a magnetic driving field. In this thesis, we measure the electrical tunability of phosphorus donors in silicon and use the extracted parameters to estimate the effects of electric-field noise on qubit coherence times. Our measurements show that donor ionization may set in before electron spins can be sufficiently tuned. We therefore explore two alternative options for qubit addressability. First, we demonstrate that nuclear spin qubits can be directly driven using electric fields instead of magnetic fields and show that this approach offers several advantages over magnetically driven spin resonance. In particular, spin transitions can occur at half the spin resonance frequency and double quantum transitions (magnetic-dipole forbidden) can occur. In a second approach to realizing tunable qubits in semiconductors, we explore the option of replacing silicon with germanium. We first measure the coherence and relaxation times for shallow donor spin qubits in natural and isotopically enriched germanium. We find that in isotopically enriched material, coherence times can exceed 1 ms and are limited by a single-phonon T1 process. At lower frequencies or lower temperatures the qubit coherence times should substantially increase. Finally, we measure the electric field tunability of donors in germanium and find a four order-of-magnitude enhancement in the spin-orbit Stark shift and confirm that the donors should be tunable by at least 4 times the electron spin ensemble linewidth (in isotopically enriched material). Germanium should therefore also be more sensitive to electrically driven nuclear magnetic resonance. Based on these results germanium is a promising alternative to silicon for spin qubits.

The knowledge of factors that may influence blood donation in Cameroon is limited. The objectives of this study are to assess the characteristics of previous and potential blood donors by exploring the religious beliefs, and knowledge and understanding of blood donations among individuals present at a district hospital. Forty-nine in-depth, semi-structured interviews were conducted among consenting, randomly selected 18 years or older community members present at a district hospital in the Adamaoua region during October and November 2011. Ninety-eight per cent (48/49) of the individuals present at this district hospital had heard of blood transfusions. Forty-seven per cent (23/49) had not previously been asked to donate blood; however, 94% (44/47) said that they would donate if given the opportunity. Thirty-three per cent (16/49) had previously donated blood to family members or for replacement, and 81% of these said they would repeat donations. The majority of both donors and non-donors were motivated to donate blood for altruistic reasons. The findings suggest that community members present at this district hospital in Cameroon may be recruited for repeat blood donations. Although the altruistic motivation to donate blood suggests that donors could be recruited from a district hospital population, targeted information about blood donations and accessible blood transfusion services need to be put in place. The study may add to the understanding of the preconditions for blood donations and the possibility to establish sustainable blood transfusion services in the Adamaoua region in Cameroon. © 2014 British Blood Transfusion Society.

Living-donor kidney transplantation has a positive influence on recipients' life expectancy and improves quality of life for patients with end-stage renal disease compared with dialysis patients. Evaluation of the physical and mental quality of life for donors can promote positive perceptions about donation and help potential donors in their decision-making process. The aim of this study was to explore the predictive factors of quality of life for living kidney donors. A cross-sectional and descriptive design was used, and the study was conducted from January to July 2013. The donors were a convenience sample of 34 participants who had undergone kidney transplant surgery >1 year earlier. The results showed that kidney donors had a low to moderate physical and mental quality of life. Multiple regression analysis revealed that financial concerns and anxiety explained 27.8% of the total variance of quality of life in the physical component. Anxiety and paid work explained 61.4% of the total variance of quality of life in the mental component. After renal transplantation, living kidney donors experienced low to moderate quality of life. Because donors are family members (siblings, sons or daughters, spouses, or parents), monthly family income is a significant issue that influences both the decision to donate and quality of life after transplantation. Our findings suggest that pre-transplantation assessment must include social workers as part of the health care team to evaluate the impact of a donor's financial status on post-transplantation quality of life.

Family discussion of organ donation has been found to double rates of family consent regarding organ donation. Therefore, family discussion is an important communication process to study in the effort to get more people to become organ donors. This investigation concerns the willingness to communicate about organ donation and its relationship to other variables and processes related to family discussion of organ donation. Previous research on willingness to communicate examined the antecedent variables of knowledge, attitude toward organ donation, and altruism. This research found that being willing to communicate about organ donation with one's family is related to prior thought and intent to sign an organ donor card, to perceiving organ donation messages as credible, and to feeling relatively low anxiety after reading organ donation messages. One week after being presented with the messages, willingness to communicate was found to be positively associated with worrying about the lack of donors, engaging in family discussion about organ donation, and having an organ donor card witnessed. It was negatively related to feeling personally uneasy about organ donation during the past week.

We report on a defect related luminescence band at 2.4 eV in aluminum nitride bulk crystals, for which we find strong indications to be related to silicon DX centers. Time resolved photoluminescence spectroscopy using a sub-bandgap excitation reveals two different recombination processes with very long decay times of 13 ms and 153 ms at low temperature. Based on the results of temperature and excitation dependent photoluminescence experiments, the process with the shorter lifetime is assigned to a donor-acceptor pair transition involving the shallow silicon donor state, which can be emptied with a thermal dissociation energy of 65 meV. The slower process with a thermalmore » quenching energy of 15 meV is assigned to the slightly deeper Si DX state known from electron paramagnetic resonance experiments, which is transferred back to the shallow donor state.« less

A definition of the triplet-triplet energy transfer reaction coordinate within the very weak electronic coupling limit is proposed, and a novel theoretical formalism is developed for its quantitative determination in terms of internal coordinates The present formalism permits (i) the separation of donor and acceptor contributions to the reaction coordinate, (ii) the identification of the intrinsic role of donor and acceptor in the triplet energy transfer process, and (iii) the quantification of the effect of every internal coordinate on the transfer process. This formalism is general and can be applied to classical as well as to nonvertical triplet energy transfer processes. The utility of the novel formalism is demonstrated here by its application to the paradigm of nonvertical triplet-triplet energy transfer involving cis-stilbene as acceptor molecule. In this way the effect of each internal molecular coordinate in promoting the transfer rate, from triplet donors in the low and high-energy limit, could be analyzed in detail.

To prevent donor loss and improve retention, it is important to understand the major deterrents to blood donation and to identify factors that can be effectively addressed by blood centers. A 30-item self-administered questionnaire was completed in 2003 by 1705 first-time and 2437 repeat US donors who had not donated in 2 to 3 years. Asian, Hispanic, black, and white first-time and repeat donors rated the importance of deterrents to donation in their decision to not return with a 1 to 5 scale. Categorical analysis of variance methods were used to compare the importance of deterrents between first-time and repeat donors of different race or ethnicity. Not having a convenient place to donate was most commonly cited as an important or very important reason for not returning by 32 to 42 percent of first-time and 26 to 43 percent of repeat respondents. Although bad treatment and poor staff skills were less of a barrier than convenience, they were more important for minority donors. Other factors such as physical side effects, foreign travel, or length of the process appeared less important. Inconvenience is a major barrier to donating, suggesting that mobile collections and increased hours of operation might help recapture lapsed donors. The finding that lapsed minority donors were more likely to give bad treatment and poor staff skills as important reasons to not donate is disconcerting in light of the changing donor demographics and increased efforts to recruit these donors.

Objectives To determine the extent to which the structured interview is used in the PharmD admissions process in US colleges and schools of pharmacy, and the prevalence and content of interviewer training. Methods A survey instrument consisting of 7 questions regarding interviews and interviewer training was sent to 92 colleges and schools of pharmacy in the United States that were accredited or seeking accreditation. Results Sixty survey instruments (65% response rate) were returned. The majority of the schools that responded (80%) used interviews as part of the PharmD admissions process. Of the schools that used an interview as part of the admissions process, 86% provided some type of interviewer training and 13% used a set of predefined questions in admissions interviews. Conclusions Most colleges and schools of pharmacy use some components of the structured interview in the PharmD admissions process; however, training for interviewers varies widely among colleges and schools of pharmacy.

IVF with donated oocytes, followed by embryo placement in the uterus of a recipient who has been primed with exogenous steroids, is a successful treatment for special cases of infertility. Preliminary results indicate that the success rate in this situation is even greater than that usually seen with normal IVF (with placement of the embryos back into the uteri of the women from whom the oocytes were recovered). Although different sources for donated oocytes have been identified, the use of "excess" oocytes from IVF cycles and the attempted collection of oocytes at the time of otherwise indicated pelvic surgery have ethical and practical problems associated with their use. We have herein described the establishment of a successful program relying on anonymous volunteers who go through ovarian stimulation, monitoring, and oocyte recovery procedures solely to donate oocytes. The potential donors go through an exhaustive screening and education process before they are accepted in the program. Psychological evaluation of our potential donors indicated a great degree of turmoil in their backgrounds and a wide variety of motivations for actually participating. Despite the extensive educational and screening process, a substantial percentage of the donors did not complete a donation cycle, having either voluntarily withdrawn or been dropped because of lack of compliance. Further investigation of the psychological aspects of participating in such a program is certainly warranted. The use of donated oocytes to alleviate specific types of infertility is quite successful, but the application of this treatment is likely to be limited by the relative unavailability of suitable oocyte donors.
