RESUMO

BACKGROUND: In Israel, there is a need to improve quality of life and health outcomes among patients and families facing cancer. Increasing awareness of, literacy about, and availability of palliative care may further this goal. AIMS: This study aimed to adapt a palliative care-focused cancer self- and family management intervention developed in the US for use in Israel. METHODS: The Managing Cancer Care (MCC) psycho-educational intervention is comprised of Managing Cancer Care: A Personal Guide (MCC-PT©) for patients and Managing Cancer Care: A Caregiver's Guide (MCC-CG©) for family caregivers. Following translation into Hebrew, an expert panel of Israeli nurses edited the MCC tool for cultural relevance. The authors then conducted qualitative interviews with patients with breast cancer and their family caregivers to obtain feedback. Data were analysed using qualitative content analysis. FINDINGS: Following recommendations from Israeli experts in oncology and/or palliative care (n=3), the authors revised intervention content specific to the US healthcare system and culture. Patients' (n=13) and family caregivers' (n=10) reported MCC as attractive (70%, 80%), topically relevant (80%, 70%), and culturally appropriate, but felt that palliative care resources should be more Israel-specific. CONCLUSION: The MCC tool is acceptable to potential users, warranting further pilot-testing.

RESUMO

OBJECTIVES: To establish, in an unselected population of London haemoglobinopathy patients, transfusion requirements, blood antigens/alloantibodies, transfusion modalities, burden of transfusion reactions and donor exposure. BACKGROUND: Haemoglobinopathy patients are among the most highly transfused patient populations, and the overall population and number of patients on long-term transfusion programmes are increasing. To provide a safe and efficacious transfusion service for patients, it is important to understand current practice, morbidity associated with transfusion, efficacy of different transfusion modalities and geno-/phenotype requirements. METHODS: Data on 4451 transfusion episodes in 760 patients from 12 London hospitals were collected retrospectively over a 6-month period in 2011. RESULTS: Alloimmunisation prevalence was 17% for sickle cell disease (SCD) and 22% for thalassaemia, most commonly anti-Rh/Kell/Kpa /Cw . Rh phenotypes differed between SCD (Ro r 59.8%/R1 r 15.9%/R2 r 15.6%) and thalassaemia (R1 R1 29.6%/R1 r 28.4%/R1 R2 15.4%). Recording of pheno-/genotypes fell below recommendations. A 2-weekly manual exchange and 3-weekly automated exchange came closest to achieving presumptive targets. In adults with thalassaemia, the mean blood requirement was 36 units per year; for SCD, erythrocytapheresis was carried out every 7 weeks with 66 units; for manual exchange, it was 38 units every 4 weeks; and for simple transfusion, it was 30 units p.a. every 4 weeks. CONCLUSION: Transfusion modality choice was influenced by the resources available-children mostly received simple transfusions, and adults received erythrocytapheresis; the relationships between frequency of exchanges/transfusion modality/target HbA% were not simple, possibly reflecting the difference in recipient erythropoiesis and consequent transfusion modality selection bias; adherence to existing and current guidelines regarding geno-/phenotyping was limited; and alloimmunisation had a low incidence and high prevalence in both disorders.

RESUMO

The reversed glove sleeve technique is a simple, available, reproducible, and cost-effective method of achieving "no touch" breast implant insertion. It allows a new glove to be used for each side, thus reducing the risk of contamination by reusing a sleeve/funnel for the subsequent implant insertion. The link between bacterial contamination of breast implants and capsular contracture is established. Further prospective evaluation of this technique is underway to show if there is benefit in reducing the risk of capsular contracture.

RESUMO

BACKGROUND: The benefits of cold pulsatile machine perfusion (MP) for the storage and transportation of kidneys donated after circulatory death are disputed. We conducted a UK-based multicenter, randomized controlled trial to compare outcomes of kidneys stored with MP versus static cold storage (CS). METHODS: Fifty-one pairs of kidneys donated after circulatory death were randomly allocated to receive static CS or cold pulsatile MP. The primary endpoint, delayed graft function, was analyzed by "intention-to-treat" evaluation. RESULTS: There was no difference in the incidence of delayed graft function between CS and MP (32/51 (62.8%) and 30/51 (58.8%) P = 0.69, respectively), although the trial stopped early due to difficulty with recruitment. There was no difference in the incidence of acute rejection, or in graft or patient survival between the CS and MP groups. Median estimated glomerular filtration rate at 3 months following transplantation was significantly lower in the CS group compared with MP (CS 34 mL/min IQR 26-44 vs MP 45 mL/min IQR 36-60, P = 0.006), although there was no significant difference in estimated glomerular filtration rate between CS and MP at 12 months posttransplant. CONCLUSIONS: This study is underpowered, which limits definitive conclusions about the use of MP, as an alternative to static CS. It did not demonstrate that the use of MP reduces the incidence of delayed graft function in donation after circulatory death kidney transplantation.

RESUMO

The Rotator interval (RI) is an anatomic space in the anterosuperior part of the glenohumeral joint. An incompetent or lax RI has been implicated in various conditions of shoulder instability and therefore RI has been frequently touted as an area that is important in preserving stability of the shoulder. Biomechanical studies have shown that repair of RI ligamentous and capsular structures decreases glenohumeral joint laxity in various directions. Clinical studies have reported successful outcomes after repair or plication of these structures in patients undergoing shoulder stabilization procedures. Although varieties of methods have been described for its closure, the optimal surgical technique is unclear with various inconsistencies in incorporation of the closure tissue. This in particular makes the analysis of the RI closure very difficult. The purposes of this study are to review the structures of the RI and their contribution to shoulder instability, to discuss the biomechanical and clinical effects of plication of RI structures in particular to anterior glenohumeral instability, to delineate the differences between an arthroscopic and open RI closure. Additionally, we have proposed a new classification system describing various techniques used during RI closure.

RESUMO

CASE: We report a rare cause of patella baja in a 25-year-old man presenting with right knee pain. He was found to have patella baja and a genu recurvatum deformity. Imaging revealed an extremely unusual variant of the patellar tendon-identified to have an intramedullary tibial insertion. A patellar tendon reconstructive procedure was performed. CONCLUSIONS: An intramedullary insertion of the patellar tendon is a fascinating and rare cause of patella baja with subsequent altered biomechanics of the extensor mechanism. We believe this is the first case report to describe its surgical presentation and an operative approach to its management.

RESUMO

BACKGROUND: With breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) now accepted as a unique (iatrogenic) subtype of ALCL directly associated with textured breast implants, we are now at a point where a sound epidemiologic profile and risk estimate are required. The aim of this article is to provide a comprehensive and up-to-date global review of the available epidemiologic data and literature relating to the incidence, risk, and prevalence of BIA-ALCL. METHODS: All current literature relating to the epidemiology of BIA-ALCL was reviewed. Barriers relating to sound epidemiologic study were identified, and trends relating to geographical distribution, prevalence of breast implants, and implant characteristics were analyzed. RESULTS: Significant barriers exist to the accurate estimate of both the number of women with implants (denominator) and the number of cases of BIA-ALCL (numerator), including poor registries, underreporting, lack of awareness, cosmetic tourism, and fear of litigation. The incidence and risk of BIA-ALCL have increased dramatically from initial reports of 1 per million to current estimates of 1/2,832, and is largely dependant on the "population" (implant type and characteristics) examined and increased awareness of the disease. CONCLUSIONS: Although many barriers stand in the way of calculating accurate estimates of the incidence and risk of developing BIA-ALCL, steady progress, international registries, and collegiality between research teams are for the first time allowing early estimates. Most striking is the exponential rise in incidence over the last decade, which can largely be explained by the increasingly specific implant subtypes examined-driven by our understanding of the pathologic mechanism of the disease. High-textured high-surface area implants (grade 4 surface) carry the highest risk of BIA-ALCL (1/2,832).

RESUMO

OBJECTIVES: Increased morbidity and mortality have been associated with weekend and night-time clinical activity. We sought to compare the outcomes of liver transplantation (LT) between weekdays and weekends or night-time and day-time to determine if 'out-of-hours' LT has acceptable results compared with 'in-hours'. DESIGN, SETTING AND PARTICIPANTS: We conducted a retrospective analysis of patient outcomes for all 8816 adult, liver-only transplants (2000-2014) from the UK Transplant Registry. OUTCOME MEASURES: Outcome measures were graft failure (loss of the graft with or without death) and transplant failure (either graft failure or death with a functioning graft) at 30 days, 1 year and 3 years post-transplantation. The association of these outcomes with weekend versus weekday and day versus night transplantation were explored, following the construction of a risk-adjusted Cox regression model. RESULTS: Similar patient and donor characteristics were observed between weekend and weekday transplantation. Unadjusted graft failure estimates were 5.7% at 30 days, 10.4% at 1 year and 14.6% at 3 years; transplant failure estimates were 7.9%, 15.3% and 21.3% respectively.A risk-adjusted Cox regression model demonstrated a significantly lower adjusted HR (95% CI) of transplant failure for weekend transplant of 0.77 (0.66 to 0.91) within 30 days, 0.86 (0.77 to 0.97) within 1 year, 0.89 (0.81 to 0.99) within 3 years and for graft failure of 0.81 (0.67 to 0.97) within 30 days. For patients without transplant failure within 30 days, there was no weekend effect on transplant failure. Neither night-time procurement nor transplantation were associated with an increased hazard of transplant or graft failure. CONCLUSIONS: Weekend and night-time LT outcomes were non-inferior to weekday or day-time transplantation, and we observed a possible small beneficial effect of weekend transplantation. The structure of LT services in the UK delivers acceptable outcomes 'out-of-hours' and may offer wider lessons for weekend working structures.

RESUMO

BACKGROUND & AIMS: Donation after circulatory death (DCD) in the UK has tripled in the last decade. However, outcomes following DCD liver transplantation are worse than for donation after brainstem death (DBD) liver transplants. This study examines whether a recipient should accept a "poorer quality" DCD organ or wait longer for a "better" DBD organ. METHODS: Data were collected on 5,825 patients who were registered on the elective waiting list for a first adult liver-only transplant and 3,949 patients who received a liver-only transplant in the UK between 1 January 2008 and 31 December 2015. Survival following deceased donor liver transplantation performed between 2008 and 2015 was compared by Cox regression modelling to assess the impact on patient survival of accepting a DCD liver compared to deferring for a potential DBD transplant. RESULTS: A total of 953 (23%) of the 3,949 liver transplantations performed utilised DCD donors. Five-year post-transplant survival was worse following DCD than DBD transplantation (69.1% [DCD] vs. 78.3% [DBD]; p <0.0001: adjusted hazard ratio [HR] 1.65; 95% CI 1.40-1.94). Of the 5,798 patients registered on the transplant list, 1,325 (23%) died or were removed from the list without receiving a transplant. Patients who received DCD livers had a lower risk-adjusted hazard of death than those who remained on the waiting list for a potential DBD organ (adjusted HR 0.55; 95% CI 0.47-0.65). The greatest survival benefit was in those with the most advanced liver disease (adjusted HR 0.19; 95% CI 0.07-0.50). CONCLUSIONS: Although DCD liver transplantation leads to worse transplant outcomes than DBD transplantation, the individual's survival is enhanced by accepting a DCD offer, particularly for patients with more severe liver disease. DCD liver transplantation improves overall survival for UK listed patients and should be encouraged. LAY SUMMARY: This study looks at patients who require a liver transplant to save their lives; this liver can be donated by a person who has died either after their heart has stopped (donation after cardiac death [DCD]) or after the brain has been injured and can no longer support life (donation after brainstem death [DBD]). We know that livers donated after brainstem death function better than those after cardiac death, but there are not enough of these livers for everyone, so we wished to help patients decide whether it was better for them to accept an early offer of a DCD liver than waiting longer to receive a "better" liver from a DBD donor. We found that patients were more likely to survive if they accepted the offer of a liver transplant as soon as possible (DCD or DBD), especially if their liver disease was very severe.

RESUMO

Kidney transplant outcomes that vary by program or geopolitical unit may result from variability in practice patterns or health care delivery systems. In this collaborative study, we compared kidney graft outcomes among 4 countries (United States, United Kingdom, Australia, and New Zealand) on 3 continents. We analyzed transplant and follow-up registry data from 1988-2014 for 379 257 recipients of first kidney-only transplants using Cox regression. Compared to the United States, 1-year adjusted graft failure risk was significantly higher in the United Kingdom (hazard ratio [HR] 1.22, 95% confidence interval [CI] 1.18-1.26, P < .001) and New Zealand (hazard ratio [HR] 1.29, 95% confidence interval [CI] 1.14-1.46, P < .001), but lower in Australia (HR 0.90, 95% CI 0.84-0.96, P = .001). In contrast, long-term adjusted graft failure risk (conditional on 1-year function) was significantly higher in the United States compared to Australia, New Zealand, and the United Kingdom (HR 0.74, 0.75, and 0.74, respectively; each P < .001). Thus long-term kidney graft outcomes are approximately 25% worse in the United States than in 3 other countries with well-developed kidney transplant systems. Case mix differences and residual confounding from unmeasured factors were found to be unlikely explanations. These findings suggest that identification of potentially modifiable country-specific differences in care delivery and/or practice patterns should be sought.

RESUMO

BACKGROUND: In Israel, palliative care (PC) services are limited. This study assessed Israeli nurses' perceived competencies and educational needs in providing PC. DESIGN: Online administration of the End-of-Life Professional Caregiver Survey (EPCS). SETTING/SUBJECTS: Oncology and PC nurses were identified through the Israel Ministry of Health and Oncology Nurses' Society. MEASUREMENTS: Demographic and practice data were analysed using analysis of variance tests to determine differences between nurse characteristics by EPCS domains. RESULTS: The sample (n=105) was 94% female, had a mean age of 48 years (SD=10.5) and 83% were Jewish Israeli. Thirty-nine percent reported PC training in nursing school and 42% felt their workplace provided little to no PC education and resources to nurses. Those with advanced degrees and those who received post-graduate PC training had higher mean scores across EPCS domains (p<0.05 for all). CONCLUSIONS: Nursing education and workplace support in PC for Israeli nurses are limited. It is hoped that these findings may inform future PC nursing education and policy in Israel.

RESUMO

Purpose The purpose of this study was to understand the experience of parenting an adolescent with type 1 diabetes (T1DM), to develop a prototype of an eHealth program for parents of adolescents with T1DM, and to evaluate the prototype content and acceptability from the perspective of parents and health care providers. Methods A multiphase method was used generating both qualitative and quantitative data at multiple time points. There were 27 parents of adolescents aged 12 to 18 years with T1DM and 16 health care providers who participated in semistructured interviews to identify parental challenges; 53 parents and 27 providers evaluated the prototype. Thematic content analysis was used to analyze interview transcripts, and descriptive statistics were used to summarize survey data. Results Challenges experienced by parents of adolescents with T1DM included understanding the developmental and hormonal changes of adolescence that affect diabetes care, feeling tension between adolescent independence and parent control, communicating without nagging or conflict, transferring diabetes care responsibility safely, dealing with feelings of stress and distress, and perceiving a lack of resources for T1DM care and insufficient personal time for self-care. In the prototype evaluation, both parents and providers found content to be relevant and provided feedback to guide the development of the full program. Conclusions Parents of adolescents with T1DM and providers expressed a need for parents to have more support in transitioning diabetes care from parent to adolescent. eHealth programs offer an ideal way to address these needs and ultimately can be linked to electronic medical records improving quality and efficiency of health care in this population.

RESUMO

BACKGROUND: A measure of donor liver quality, the donor liver index, was developed and validated for the UK population of transplant recipients. Unlike previously proposed measures, this index is only based on variables that are available at the point of retrieval, and so does not include cold ischemic time. METHODS: Indices of liver quality were based on data from the UK Transplant Registry on all 7929 liver transplants between January 2000 and December 2014. RESULTS: The donor liver index (DLI) was based on factors shown to affect graft survival, which included donor age, sex, height, type (donor after brain death or circulatory death), bilirubin, smoking history, and whether the liver was split. A separate index (DLI1) looking at 1-year survival showed donor cardiac disease, black ethnicity, and steatosis to be additional risk factors. A strong association was found between DLI and whether or not a surgeon accepts an offered liver for transplant, with a marked fall in acceptance rates for livers with an index greater than 1.31. Since 2000, there has been a notable reduction in the quality of livers transplanted, coupled with variation between the 7 UK liver transplant centers in risk appetite. CONCLUSIONS: The DLI is an index of liver quality which enables analysis of the changing trends in liver quality and center behavior. DLI1 enables identification of factors affecting shorter-term survival, and perhaps identifies a cohort of livers that may benefit from novel preservation technologies.

RESUMO

BACKGROUND & AIMS: Comparing liver transplant (LT) programmes internationally can improve outcomes by stimulating cross-national learning. Yet, comparison of crude outcomes, by using registry data, is limited by missing data, not allowing proper risk-adjustment for donor- and recipient-related factors. The objective of this study was to compare two European LT programmes based on high-quality national longitudinal databases prospectively collected in Italy and UK respectively. METHODS: We undertook a multicentre, international cohort study including all adults who underwent a first single organ LT in Italy (N = 1480) and the UK (N = 1003) between June 2007 and May 2009. RESULTS: Italian donors were much older compared to the UK ones. Hepatitis C virus infection and hepatocellular carcinoma had higher prevalence in the Italian cohort compared to the UK one (47.5% vs. 23.1%, and 47.2% vs. 17.1% respectively). Centres' volume differed significantly, with five centres out of seven in UK vs. only two out of 20 in Italy performing >60 transplants per year. No national strategies to drive the donor-recipient matching were identified in both countries. After appropriate adjustment, a higher risk of early transplant loss was identified in the Italian cohort, whereas no differences were found in the 3-year survival rates. CONCLUSIONS: International comparison of LT programmes provides the opportunity for benchmarking between heterogeneous healthcare systems and should ideally become a vital part of national quality assurance programmes. This requires the implementation of a standardized methodology for data collection to appropriately weigh each country's patient case-mix and donor and recipients risk factors.

RESUMO

The use of kidneys from controlled donation after circulatory death (DCD) donors has the potential to markedly increase kidney transplants performed. However, this potential is not being realized because of concerns that DCD kidneys are inferior to those from donation after brain-death (DBD) donors. The United Kingdom has developed a large and successful controlled DCD kidney transplant program that has allowed for a substantial increase in kidney transplant numbers. Here we describe recent trends in DCD kidney donor activity in the United Kingdom, outline aspects of the donation process, and describe donor selection and allocation of DCD kidneys. Previous UK Transplant Registry analyses have shown that while DCD kidneys are more susceptible to cold ischemic injury and have a higher incidence of delayed graft function, short- and medium-term transplant outcomes are similar in recipients of kidneys from DCD and DBD donors. We present an updated, extended UK registry analysis showing that longer-term transplant outcomes in DCD donor kidneys are also similar to those for DBD donor kidneys, and that transplant outcomes for kidneys from expanded-criteria DCD donors are no less favorable than for expanded-criteria DBD donors. Accordingly, the selection criteria for use of kidneys from DCD donors should be the same as those used for DBD donors. The UK experience suggests that wider international development of DCD kidney transplantation programs will help address the global shortage of deceased donor kidneys for transplantation.

RESUMO

Pancreas graft failure rates remain substantial. The PDRI can be used at the time of organ offering, to predict one-year graft survival. This study aimed to validate the PDRI for a UK population. Data for 1021 pancreas transplants were retrieved from a national database for all pancreas transplants. Cases were categorized by PDRI quartile and compared for death-censored graft survival. Significant differences were observed between the UK and US cohorts. The PDRI accurately discriminated graft survival for SPK and was associated with a hazard ratio of 1.52 (P = 0.009) in this group. However, in the PTA and PAK groups, no association between PDRI quartile and graft survival was observed. This is the largest study to validate the PDRI in a European cohort and has shown for the first time that the PDRI can be used as a tool to predict graft survival in SPK transplantation, but not PTA or PAK transplantation.

RESUMO

BACKGROUND: Use of kidneys donated after controlled circulatory death has increased the number of transplants undertaken in the UK but there remains reluctance to use kidneys from older circulatory-death donors and concern that kidneys from circulatory-death donors are particularly susceptible to cold ischaemic injury. We aimed to compare the effect of donor age and cold ischaemic time on transplant outcome in kidneys donated after circulatory death versus brain death. METHODS: We used the UK transplant registry to select a cohort of first-time recipients (aged ≥ 18 years) of deceased-donor kidneys for transplantations done between Jan 1, 2005, and Nov 1, 2010. We did univariate comparisons of transplants from brain-death donors versus circulatory-death donors with χ tests for categorical data and Wilcoxon tests for non-parametric continuous data. We used Kaplan-Meier curves to show graft survival. We used Cox proportional hazards regression to adjust for donor and recipient factors associated with graft-survival with tests for interaction effects to establish the relative effect of donor age and cold ischaemia on kidneys from circulatory-death and brain-death donors. FINDINGS: 6490 deceased-donor kidney transplants were done at 23 centres. 3 year graft survival showed no difference between circulatory-death (n=1768) and brain-death (n=4127) groups (HR 1·14, 95% CI 0·95-1·36, p=0·16). Donor age older than 60 years (compared with <40 years) was associated with an increased risk of graft loss for all deceased-donor kidneys (2·35, 1·85-3·00, p<0·0001) but there was no increased risk of graft loss for circulatory-death donors older than 60 years compared with brain-death donors in the same age group (p=0·30). Prolonged cold ischaemic time (>24 h vs <12 h) was not associated with decreased graft survival for all deceased-donor kidneys but was associated with poorer graft survival for kidneys from circulatory-death donors than for those from brain-death donors (2·36, 1·39-4·02, p for interaction=0·004). INTERPRETATION: Kidneys from older circulatory-death donors have equivalent graft survival to kidneys from brain-death donors in the same age group, and are acceptable for transplantation. However, circulatory-death donor kidneys tolerate cold storage less well than do brain-death donor kidneys and this finding should be considered when developing organ allocation policy.

RESUMO

BACKGROUND: The risk that a positive smoking history in lung donors could adversely affect survival of transplant recipients causes concern. Conversely, reduction of the donor pool by exclusion of donors with positive smoking histories could compromise survival of patients waiting to receive a transplant. We examined the consequences of donor smoking on post-transplantation survival, and the potential effect of not transplanting lungs from such donors. METHODS: We analysed the effect of donor smoking on 3 year survival after first adult lung transplantation from brain-dead donors done between July 1, 1999, and Dec 31, 2010, by Cox regression modelling of data from the UK Transplant Registry. We estimated the effect of acceptance of lungs from donors with positive smoking histories on survival and compared it with the effect of remaining on the waiting list for a potential transplant from a donor with a negative smoking history donor, by analysing all waiting-list registrations during the same period with a risk-adjusted sequentially stratified Cox regression model. FINDINGS: Of 1295 lung transplantations, 510 (39%) used lungs from donors with positive smoking histories. Recipients of such lungs had worse 3 year survival after transplantation than did those who received lungs from donors with negative smoking histories (unadjusted hazard ratio [HR] 1·46, 95% CI 1·20-1·78; adjusted HR 1·36, 1·11-1·67). Independent factors affecting survival were recipient's age, donor-recipient cytomegalovirus matching, donor-recipient height difference, donor's sex, and total ischaemic time. Of 2181 patients registered on the waiting list, 802 (37%) died or were removed from the list without receiving a transplant. Patients receiving lungs from donors with positive smoking histories had a lower unadjusted hazard of death after registration than did those who remained on the waiting list (0·79, 95% CI 0·70-0·91). Patients with septic or fibrotic lung disease registered in 1999-2003 had risk-adjusted hazards of 0·60 (95% CI 0·42-0·87) and 0·39 (0·28-0·55), respectively. INTERPRETATION: In the UK, an organ selection policy that uses lungs from donors with positive smoking histories improves overall survival of patients registered for lung transplantation, and should be continued. Although lungs from such donors are associated with worse outcomes, the individual probability of survival is greater if they are accepted than if they are declined and the patient chooses to wait for a potential transplant from a donor with a negative smoking history. This situation should be fully explained to and discussed with patients who are accepted for lung transplantation. FUNDING: National Health Service Blood and Transplant.

RESUMO

Deciding to use an organ from a donor with a primary central nervous system (CNS) tumor necessitates offsetting the risk of tumor transmission with the chances of survival if the patient waits for another offer of a transplant. Published data vary in the quoted risk of tumor transmission. We used data obtained by reviewing 246 UK recipients of organs taken from donors with CNS tumors and found no evidence of a difference in overall patient mortality for recipients of a kidney, liver, or cardiothoracic organ, compared with recipients of organs from donors without a CNS tumor. Recent publication of the UK experience of transplanting organs from CNS tumor donors found no transmission in 448 recipients of organs from 177 donors with a primary CNS tumor (Watson et al., Am J Transplant 2010; 10: 1437). This 0% transmission rate is associated with an upper 95% confidence interval limit of 1.5%. Using a series of assumptions of risk, we compared the risks of dying as a result of the transmission of a primary brain tumor with the risks of dying if not transplanted. On this basis, the use of kidneys from a donor with a primary CNS tumor provides a further 8 years of life over someone who waited for a donor who did not have a primary CNS tumor, in addition to the life years gained by the transplant itself. The benefits for the recipients of livers and cardiothoracic organs were less, but there was no disadvantage in the impact on life expectancy.
