RESUMO

Objective: To obtain a comprehensive overview of organ donation, organ utilization, and discard in the entire donation process in Colombia. Methods: A retrospective study of 1 451 possible donors, distributed in three regions of Colombia, evaluated in 2022. The general characteristics, diagnosis, and causes of contraindication for potential donors were described. Results: Among the 1 451 possible donors, 441 (30.4%) fulfilled brain death criteria, constituting the potential donor pool. Families consented to organ donation in 141 medically suitable cases, while 60 instances utilized legal presumption, leading to 201 eligible donors (13.9%). Of those, 160 (11.0%) were actual donors (in whom operative incision was made with the intent of organ recovery or who had at least one organ recovered). Finally, we identified 147 utilized donors (10.1%) (from whom at least one organ was transplanted). Statistically significant differences were found between age, sex, diagnosis of brain death, and donor critical pathway between regions. A total of 411 organs were transplanted from 147 utilized donors, with kidneys being the most frequently procured and transplanted organs, accounting for 280 (68.1%) of the total. This was followed by 85 livers (20.7%), 31 hearts (7.5%), 14 lungs (3.4%), and 1 pancreas (0.2%). The discard rate of procured deceased donors was 8.1%. Conclusions: About one-tenth of donors are effectively used for transplantation purposes. Our findings highlight areas of success and challenges, providing a basis for future improvements in Colombia.

RESUMO

Germline predisposition to haematological cancers is increasingly being recognised. Widespread adoption of high-throughput and whole genome sequencing is identifying large numbers of causative germline mutations. Constitutional pathogenic variants in six genes (DEAD-box helicase 41 [DDX41], ETS variant transcription factor 6 [ETV6], CCAAT enhancer binding protein alpha [CEBPA], RUNX family transcription factor 1 [RUNX1], ankyrin repeat domain containing 26 [ANKRD26] and GATA binding protein 2 [GATA2]) are particularly significant in increasing the risk of haematological cancers, with variants in some of these genes also associated with non-malignant syndromic features. Allogeneic blood and marrow transplantation (BMT) is central to management in many haematological cancers. Identification of germline variants may have implications for the patient and potential family donors. Beyond selection of an appropriate haematopoietic stem cell donor there may be sensitive issues surrounding identification and counselling of hitherto asymptomatic relatives. If BMT is needed, there is frequently a clinical urgency that demands a rapid integrated multidisciplinary approach to testing and decision making involving haematologists in collaboration with Clinical and Laboratory Geneticists. Here, we present best practice consensus guidelines arrived at following a meeting convened by the UK Cancer Genetics Group (UKCGG), the Cancer Research UK (CRUK) funded CanGene-CanVar research programme (CGCV), NHS England Genomic Laboratory Hub (GLH) Haematological Oncology Malignancies Working Group and the British Society of Blood and Marrow Transplantation and Cellular Therapy (BSBMTCT).

RESUMO

BACKGROUND: The COVID-19 pandemic has caused major disruption to health systems, with allogeneic haemopoietic cell transplant (alloHCT) services a particularly vulnerable area. Ongoing provision of alloHCT has required dynamic responses at national and local levels. In Australia and New Zealand (ANZ), a high reliance on unrelated donors from overseas registries has posed an additional challenge. AIMS: To describe the impact of COVID-19 on alloHCT services in ANZ in the first year of the pandemic. METHODS: Data from the national alloHCT patient and unrelated donor registries were extracted for a 2-year time frame. Comparisons were made between a pre-pandemic period of 1 March 2019 to 29 February 2020 and the corresponding dates during the pandemic, 1 March 2020 to 28 February 2021. RESULTS: There was a 13% decrease in the number of allogeneic transplants, a reversal of steady increases in previous years, with the largest decrease in unrelated donor transplants. Local donors supplied a greater proportion of unrelated stem cell products. With a switch to universal cryopreservation, the time from request of a product to infusion increased by a median of 25.5 days for overseas products and 14 days for local products. There was a significant increase in the number of products collected but not used. CONCLUSIONS: A strong public health response and coordinated transplant community activities allowed for safe provision of alloHCT in ANZ; however, our data suggest that the timely delivery of allogeneic transplants was affected by the COVID-19 pandemic. Continued dedicated efforts are required to minimise further impacts.

RESUMO

Background: The quality of the wound healing at the donor site significantly determines the overall condition of the burn patient, the extent of wound fluid and protein losses, the severity of any systemic in-flammatory reaction, and the intensity of the pain syndrome. It is known that the stromal vas-cular fraction (SVF) has a beneficial effect on the healing of wound defects. This study is aimed at assessing the safety and effectiveness of the application of the SVF of autologous adipose tis-sue to stimulate wound healing of the donor site in patients with burns. Methods: This placebo-controlled clinical study included 38 patients with third-degree thermal skin burns. The patients underwent liposuction, enzymatic isolation of the SVF, and intradermal injection of the preparation into the wounds in the donor site, followed by tewametry, cutome-try, thermography and biopsy after 12 days. Quantitative indicators were compared using the Mann-Whitney test for unrelated groups and the Wilcoxon test for related groups. Spearman's rank correlation coefficient (RS) was used to assess the correlation. Results: Epithelization of the wounds in all patients was seen over an average area of 88 (84;92) %, there being no significant differences between the actual and the control wound sites for this parameter. Transdermal water loss in the test wound sites was 2 times lower than in the control sites (P = 0.001). The wound donor sites regained their temperature distribution faster than the control sites (P = 0.042). Histological preparations of the skin of the wound sites revealed that their epidermal layer was 19% thicker compared to the controls (P = 0.043). It should be noted that five adverse events related to manipulations in the postoperative period were registered. Conclusion: Transplantation of SVF autologous adipose tissue into the wound area in most clinical cases proceeded without complications. The area of epithelialization of wound areas af-ter the introduction of SVF did not change, although a significant decrease in transdermal water loss was observed in the wound areas with an improvement in their thermoregulation and an increase in the thickness of the epidermis.

RESUMO

BACKGROUND AND OBJECTIVES: The transverse musculocutaneous gracilis (TMG) flap has gained popularity for breast reconstruction. However, the literature regarding its donor site morbidity is heterogeneous. This systematic review sought to clarify the evidence on donor site morbidity. METHODS: A systematic literature search was conducted. We included all articles reporting on donor-site morbidity of the TMG flap for breast reconstruction. The results were analyzed in R and its extension meta. A generalized linear mixed model was used to combine proportions and their 95% confidence intervals (CIs) in a random-effects meta-analysis. RESULTS: Nineteen articles provided an overall sample of 843 TMG flaps. The total flap loss was low at 2% (95% CI, 1%-3%). All patients were normal weight (pooled body mass index 22.75, 95% CI, 21.88-23.63). The incidence of wound dehiscence (8%, 95% CI, 4%-16%), seroma (4%, 95% CI, 2%-7%), hematoma (2%, 95% CI, 1%-4%) and infection (0%-5%) on the TMG donor site was low. Functional impairments included sensory disturbance (0%-74%), motoric deficits (0%-50%), and changes in the genital region (0%-24%), all of which were modest. CONCLUSIONS: This review confirms the safety and low donor site morbidity of the TMG flap in normal-weight patients, which is comparable to that of other popular free flaps in breast reconstruction.

RESUMO

AIM: Children's burns care in Australasia is performed by paediatric surgeons and by plastic surgeons. The aim was to determine practices regarding the donor site wound (DSW), and to explore any differences by training scheme or nature of unit (paediatric vs. mixed). METHODS: Online survey of Australasian burns surgeons. RESULTS: Forty surgeons responded. 23/40 paediatric surgeons, 23/40 worked in a stand-alone children's burns unit. All used powered dermatomes. Alginates were the most common DSW dressing. Idealised dressings favour patient factors over cost. Plastic, and mixed-practice, surgeons use a broader range of dermatome settings in children >1 year. Mixed practice surgeons use thicker settings. All surgeons see pain as a common DSW problem. Paediatric surgeons recognise itch as a problem. CONCLUSIONS: While there are differences related to training scheme and the mix of patients being treated, there is a broader commonality of practice.

RESUMO

Dietary supplement use is high among US adults, with the intention by users to promote overall health and wellness. Kidney donors, who are selected based on their overall good health and wellness, can have high utilization rates of dietary supplements. We provide a framework for the evaluation of living kidney donors and use of dietary supplements. In this review, dietary supplements will include any orally administered dietary or complementary nutritional products, but excluding micronutrients (vitamins and minerals), food, and cannabis. Use of dietary supplements can influence metabolic parameters that mask future risk for chronic illness such as diabetes and hypertension. Dietary supplements can also alter bleeding risk, anesthesia and analgesic efficacy, and safety in a perioperative period. Finally, postdonation monitoring of kidney function and risk for supplement-related nephrotoxicity should be part of a kidney donor educational process. For practitioners evaluating a potential kidney donor, we provide a list of the most commonly used herbal supplements and the effects on evaluation in a predonation, perioperative donation, and postoperative donation phase. Finally, we provide recommendations for best practices for integration into a comprehensive care plan for kidney donors during all stages of evaluation. We recommend avoidance of dietary supplements in a kidney donor population, although there is a paucity of data that identifies true harm. Rather, associations, known mechanisms of action, and common sense suggest that we avoid use in this population.

RESUMO

BACKGROUND: Compensation of contralateral kidney function after living-donor kidney donation is well known, and many predictive factors have been proposed. However, no prediction model has been proposed. This study was performed to establish a tool with which to estimate the degree of compensation of the contralateral kidney after living-donor kidney donation. METHODS: We retrospectively analyzed 133 living donors for renal transplantation in our institution. We defined a favorable compensation as a post-donation estimated glomerular filtration rate (eGFR) at 1 year (calculated by the Chronic Kidney Disease Epidemiology Collaboration equation) of > 60% of the pre-donation eGFR. We analyzed the living donors' clinical characteristics and outcomes. RESULTS: The median (range) donor age was 59 (24-79) years, median (range) body mass index was 22.9 (16.8-32.7) kg/m2, and median (range) body surface area was 1.6 (1.3-2.0) m2. All donors were Japanese, and 73% of the donors were biologically related. The median (range) donor pre-donation eGFR was 108.7 (82-144) ml/min/1.73 m2, and the median (range) post-donation eGFR at 1 year was 86.9 (43-143) ml/min/1.73 m2. Eighty-six percent of donors had compensatory hypertrophy. In the univariate analysis, age, female sex, history of hypertension, body surface area, and pre-donation eGFR were significantly associated with hypertrophy (p < 0.05). In the multivariate analysis, age, female sex, history of hypertension, and ratio of the remnant kidney volume to body weight were significantly associated with hypertrophy (p < 0.05). Based on these results, we created a compensation prediction score (CPS). The median (range) CPS was 8.7 (1.1-17.4). Receiver operating characteristic analysis showed strong diagnostic accuracy for predicting favorable compensation (area under the curve, 0.958; 95% confidence interval, 0.925-0.991, p < 0.001). The optimal cut-off value of the CPS was 5.0 (sensitivity, 92.0%; specificity, 89.5%). The CPS had a strong positive correlation with the post-donation eGFR (R = 0.797, p < 0.001). CONCLUSION: The CPS might be useful tool with which to predict a favorable compensation of the contralateral kidney and remnant kidney function. If the CPS is low, careful management and follow-up might be necessary. Further investigations are needed to validate these findings in larger populations.

RESUMO

BACKGROUND: The magnitude of renal function recovery after kidney donation differs in donors with a heterogeneous background. Preoperative assessment of candidates with potentially unfavorable renal functional compensation is critical when baseline kidney function is marginal. We explored the significance of preserved kidney volume (PKV) and known preoperative risk factors for the prediction of unfavorable renal function compensation. METHODS: We enrolled 101 living donors for whom a 1-mm sliced enhanced computed tomography scan was performed preoperatively and clinical data could be collected up to 1 year after donation. The donors whose estimated glomerular filtration rate (eGFR) at 1 year after donation was 70% or higher of baseline eGFR were assigned to the "favorable renal compensation" group and the others to the "unfavorable renal compensation" group. RESULTS: Age, sex, and preoperative serum uric acid level were not significant predictors for "unfavorable renal compensation." Multivariable logistic regression analysis revealed that body mass index (BMI) and body surface area (BSA)-adjusted PKV were independent preoperative risk factors for "unfavorable renal compensation" (adjusted odds ratio, 1.342 and 0.929, respectively). Hypertension and preoperative eGFR were not independent predictors when adjusted with BMI and BSA-adjusted PKV. Receiver operative characteristic analysis revealed that the predictive equation with the two independent predictors yielded a good accuracy to detect donor candidates with unfavorable renal functional compensation (area under the curve = 0.803), and the optimal cut-off values were identified as 23.4 kg/m2 for BMI and 107.3 cm3/m2 for BSA-adjusted PKV. CONCLUSIONS: BMI and BSA-adjusted PKV may be useful to select candidates with potentially unfavorable renal function compensation before kidney donation.

RESUMO

INTRODUCTION: Recipient travel distance may be an unrecognized burden in lung transplantation. DESIGN: Retrospective single-center cohort study of all adult (≥18 years) first-time lung-only transplants from January 1, 2010, until February 28, 2017. Recipient distance to transplant center was calculated using the linear distance from the recipient's home zip code to the Cleveland Clinic in Cleveland, Ohio. RESULTS: 569 recipients met inclusion criteria. Posttransplant graft survival was 85%, 88%, 91%, and 91% at 1 year and 49%, 52%, 57%, and 56% at 5 years posttransplant for recipient travel distances of ≤50, >50 to ≤250, >250 to ≤500, and >500 miles, respectively ( P = .10). DISCUSSION: We found no significant relationship between recipient travel distance and posttransplant graft survival. In carefully selected recipients, travel distance is not a significant barrier to successful posttransplant outcomes which may be important for patient decision-making and donor allocation policy. These data should be validated in a national cohort.

RESUMO

CONTEXT: Patients never declared brain dead may represent an additional source of donor organs. OBJECTIVE: To determine the number of likely brain dead potential donors who are never declared brain dead and to compare them with brain dead and donation after cardiac death potential organ donors. DESIGN, SETTING, AND PARTICIPANTS: This study was a retrospective chart review of all catastrophically brain-injured patients referred to a single-organ procurement organization (OPO) over a 4-year period. This study identified 159 likely brain dead potential organ donors, 902 brain dead potential organ donors, and 357 potential donation after circulatory death donors over a 4-year period. INTERVENTIONS: None. MAIN OUTCOME MEASURES: This study did not predetermine outcome measures before data collection because the study group, likely brain dead potential organ donors, had not previously been described. RESULTS: Likely brain dead potential donors were significantly older than brain dead potential donors ( P < .0001) but were otherwise not different demographically. They were more likely to be a late referral to the OPO ( P < .0001) and less likely to be in the donor registry ( P < .0001). The most commonly identified factors associated with a failure to declare brain death were an unwillingness to continue supportive care by the family, premention of donation, a nontimely imminent death referral, known prior objection to donation, terminal instability, and a lack of cooperation with the OPO.

RESUMO

BACKGROUND: Organ donation research has centered on improving donation rates rather than focusing on the experience and impact on substitute decision makers. The purpose of this study was to document donor and nondonor family experiences, as well as lasting impacts of donation. METHODS: We used a qualitative exploratory design. Semistructured interviews of 27 next-of-kin decision makers were conducted, transcribed verbatim, and entered into qualitative software. We analyzed the process-based reflections using inductive coding and thematic analysis techniques. RESULTS: Four broad and interrelated themes emerged from the data: empathetic care, information needs, donation decision, and impact and follow-up. The donation experience left lasting impacts on family members due to lingering, unanswered questions. Suggested solutions to improve the donor experience for families included providers employing multimodal communication, ensuring a proper setting for family meetings, and the presence of a support person. DISCUSSION: We now have improved our understanding of the donation process from the perspective of and final impression from the next of kin. To our knowledge, this is the largest cohort interviewed in Canada. We have explored families' experiences, which included but did not end with donation. We learned that despite being appreciative of nurses, physicians, and organ and tissue donation coordinators, family members were often troubled by unanswered questions. CONCLUSION: This study described donor and nondonor family experiences with donation as well as lasting impacts. Addressing unanswered questions should be done in a place sufficiently remote from the donation event to enhance the family members' understanding and well-being.

RESUMO

BACKGROUND: The Australian and New Zealand Intensive Care Society and the Australasian Transplant Coordinators Association provide recommendations on the physiological management of brain-dead donors. PROBLEM STATEMENT: How often physiological targets are prescribed for brain-dead donors in Australian intensive care units (ICUs), and how well these compare to recommended targets is unknown. It is also unknown how often recommended targets are achieved, irrespective of prescribed targets. METHODS: We performed a retrospective, observational quality control study in 81 adult (>18 years) brain-dead donors to describe how often physiological targets were prescribed, comparing these to current guidelines. We determined the proportion of observations within the recommended target range, irrespective of any prescribed target. We aimed to identify poor adherence to recommended targets to guide future quality improvement initiatives. OUTCOMES: Seventy-four (91%) donors had at least 1 prescribed physiological target written on the ICU chart, with a median of 2 (range 2-5), and a maximum of 13 targets. Prescribed targets appeared to adhere well with recommended targets. Most recommended physiological targets were met irrespective of any prescribed target. However, one-quarter of serum sodium observations and one-third of blood glucose levels were above the recommended target. IMPLICATIONS FOR PRACTICE: Quality improvement initiatives are required to improve the prescription of physiological targets in brain-dead donors in South Australia. Serum sodium and serum glucose targets were not met. However, this most likely reflects the need for current guidelines to be updated in line with current evidence.

RESUMO

INTRODUCTION: South Africa is faced with very low deceased organ donor numbers. Often, sociocultural practices, which are thought to be fundamentally opposed to deceased organ donation, are hailed as the cause. However, other factors such as context, social perceptions, and clinical environment may play a role. AIM: The aim of this article is to present research that explored communication in organ transplant and identified barriers to organ donation decisions in a province of South Africa. METHODS: Qualitative methods were used. Thirty semistructured interviews with transplant professionals and 2 focus groups with transplant coordinators took place across 6 health institutions in Gauteng Province. RESULTS: Barriers that may prevent transplant professionals from referring potential donors were identified: The wider public and transplant professionals may be suspicious of biomedicine and have a perception that people could be killed for their organs. Organ donation was sometimes framed as "murder," "killing," or a "bunch of vultures." Doctors may be unwilling to refer brain-dead patients, as this was seen as failing in one's professional duty to cure the patient. The role of sociocultural practices was inconclusive, with the sample divided based on the extent of their influence. CONCLUSION: Low donor numbers may be a manifestation of barriers to referral in the clinical setting. These barriers interplay in a context of suspicion and are framed by a clinical transplant discourse that is sometimes loaded with negative connotation. Sociocultural practices are influential, but they may not be the overriding cause of low donor numbers.

RESUMO

BACKGROUND: Aggressive management of patients prior to and after determination of death by neurologic criteria (DNC) is necessary to optimize organ recovery, transplantation, and increase the number of organs transplanted per donor (OTPD). The effects of time management are understudied but potentially pivotal component. The objective of this study was to analyze specific time points (time to DNC, time to procurement) and the time intervals between them to better characterize the optimal timeline of organ donation. METHODS: Using data over a 5-year time period (2011-2015) from the largest US OPO, all patients with catastrophic brain injury and donated transplantable organs were retrospectively reviewed. Active smokers were excluded. Maximum donor potential was seven organs (heart, lungs [2], kidneys [2], liver, and pancreas). Time from admission to declaration of DNC and donation was calculated. Mean time points stratified by specific organ procurement rates and overall OTPD were compared using unpaired t-test. RESULTS: Of 1719 Declaration of Death by Neurologic Criteria organ donors, 381 were secondary to head trauma. Smokers and organs recovered but not transplanted were excluded leaving 297 patients. Males comprised 78.8%, the mean age was 36.0 (±16.8) years, and 87.6% were treated at a trauma center. Higher donor potential (>4 OTPD) was associated with shorter average times from admission to brain death; 66.6 versus 82.2 hours, P = 0.04. Lung donors were also associated with shorter average times from admission to brain death; 61.6 versus 83.6 hours, P = 0.004. The time interval from DNC to donation varied minimally among groups and did not affect donation rates. CONCLUSIONS: A shorter time interval between admission and declaration of DNC was associated with increased OTPD, especially lungs. Further research to identify what role timing plays in the management of the potential organ donor and how that relates to donor management goals is needed.

RESUMO

Nurses are the largest group of health-care professionals, yet they are not uniformly educated regarding transplantation and organ donation. The future of transplantation hinges on education of this group. Before meaningful studies can be conducted, an instrument to measure attitudes and commitment to organ transplantation is needed. The purpose of this study was to examine content and construct validity as well as establish internal reliability of an investigator-developed online instrument to measure nurses' attitudes and commitment to organ transplantation by registered nurses. The online instrument was administered to registered nurses enrolled in transplantation electives at the University of Alabama in Huntsville and Vanderbilt University. Exploratory factor analysis revealed 4 components with eigenvalues over 1.0. The components were as follows: (1) desire to work in transplantation, (2) confidence in transplantation advocacy, (3) organ donation advocacy, and (4) procurement. Internal consistency of the revised instrument was established (α = .94). The Transplant-Registered Nurse (TXP-RN) instrument is a new instrument with excellent reliability and validity that can be used to measure attitudes and knowledge of American nurses about organ donation and transplantation. This important step is necessary before educational interventions can be accurately assessed.

RESUMO

CONTEXT: There is a critical shortage of donor lungs however, considerable ethical considerations are associated with the conduct of research to optimize care of the potential organ donor. OBJECTIVE: To investigate pathways of consent, respiratory care by physiotherapists and donation rates to contextualize future research on physiotherapy effects on donor lung suitability for procurement. DESIGN: Retrospective audit. SETTING: Australian tertiary hospital. PATIENTS: Potential organ donors (defined as patients who may have been eligible to donate organs for transplantation via either brain death or circulatory death) 75 years or younger presenting to the emergency department or the intensive care unit (ICU) between September 2011 and December 2012. MAIN OUTCOME MEASURES: Donation rates, timing of organ procurement from initial hospital presentation, number of persons designated to make health-care decisions approached for and consenting to donation and clinical research, and number of patients assessed and/or treated by physiotherapists. RESULTS: Records of 65 potentially eligible donors were analyzed. Eighteen (28%) of the 65 became donors. Organ procurement occurred at a median of 48 hours (interquartile range: 34-72 hours) after ICU admission. All decision-makers approached regarding participation in clinical research (4 [6%] of the 65) consented. Physiotherapists assessed 48 (74%) of the 65 patients at least once and provided 28 respiratory treatments to 18 (28%) of the 65 patients, including lung hyperinflation and positioning. Limitations were the retrospective, single-center design and the "potential organ donor" definition. CONCLUSION: Organ procurement occurs early. There is potential for early intervention to improve lung donor rates. Randomized controlled trials investigating protocolized respiratory packages of care may increase the potential donor pool and transplantation rates.

RESUMO

INTRODUCTION: In the Netherlands, there is a constant shortage in donor organs, resulting in long waiting lists. The decision to register as organ donor is associated with several demographic, cultural, and personal factors. Previous research on attitudes and motivations toward blood and organ donations provided similar results. RESEARCH QUESTION: The current study investigated demographic, cultural, and personal determinants of organ donation registration among current Dutch blood donors. DESIGN: We used data from Donor InSight (2012; N = 20 063), a cohort study among Dutch blood donors, to test whether age, gender, religious and political preferences, donor attitude, and altruism predicted organ donor registration among current blood donors. RESULTS: Organ donors were more often represented in the blood donor population compared to the general Dutch population. Women showed a higher propensity to be registered as organ donor. Higher education as well as higher prosocial value orientation, prosocial behavior, that is, doing volunteer work, and awareness of need significantly associated with being registered as organ donor. Religious denomination negatively predicted organ donation registration across all faiths. DISCUSSION: Results are discussed in light of cultural context, and possible implications for improving information provision and recruitment are mentioned.

RESUMO

Context and Setting: New Mexico (NM) is a minority-majority state. Despite its unique cultural characteristics and documented ethnic/racial disparities in deceased organ donation (DOD), past studies did not explore predictors of organ donor registration status (ODRS) in this state. OBJECTIVES: This study aimed at identifying demographic, cultural, and religious predictors of ODRS among a diverse sample of young adults in NM. DESIGN: This study focused on recruitment of American Indian, Hispanic, and Asian American participants through online social network sites and university listservs. Participants (N = 602) answered an online survey. The largest racial/ethnic group included American Indians (n = 200). Main outcome measures included ODRS, demographics, religious affiliation, and open-ended question on reasons for objections to DOD. RESULTS: Race/ethnicity, religion, and educational attainment were significant predictors of ODRS. Non-Hispanic whites (NHWs) were most likely to be registered as donors, with no significant difference between NHWs and Asians or Pacific Islanders. Non-Catholic Christians were most likely to be registered donors, followed by Catholics, practitioners of American Indian/Native American traditional religions, and Hindus, with Buddhists the least likely to register. This pattern was consistent with the propensity of individuals from these religious groups to cite religious objections to DOD. Finally, respondents who had graduated from high schools in NM were 2.3 times less likely to be registered as organ donors compared to those who had graduated in other states. CONCLUSION: This study provides evidence for the need for culturally tailored interventions targeting diverse communities in NM.

RESUMO

In March 2008, a 19-year-old woman required emergency liver transplantation due to acute-on-chronic liver failure. No living donor candidate was available. A marginal deceased liver that had been rejected by all the other centers was offered. The liver belonged to a 93-year-old woman and contained a hydatid cyst. Because of low donation rates in our country, we chose to accept the 93-year-old liver. The postoperative early and late courses were fortunately uneventful. Five years after transplantation, the woman became pregnant and gave birth to a healthy female baby. Today, the ages of the baby, mother, and the transplanted liver are 1, 26, and 100 years, respectively. A nonagenarian liver with hydatid disease was able to sustain its viability in a younger woman after transplant and also helped her bring in a new life into the world.
