RESUMO
Kidney transplant recipients have an increased risk of cytomegalovirus (CMV) infection and disease. A strategy for mitigating the risk of CMV infection in kidney transplant recipients has not yet been established in Taiwan. The Transplantation Society of Taiwan aimed to develop a consensus by expert opinion on the prevention and management of CMV infection. Based on the results of Consensus Conference, we suggested low-dose valganciclovir prophylaxis (450 mg once daily) for kidney transplant recipients. The prophylaxis duration was ≥6 months for high-risk (D+/R-) patients and 3 months for moderate-risk (R+) patients. Even for low-risk (D-/R-) patients, prophylaxis for at least 3 months is recommended because of the high seroprevalence of CMV in Taiwan. CMV prophylaxis was suggested after anti-thymocyte globulin treatment but not after methylprednisolone pulse therapy. Routine surveillance after prophylaxis, secondary prophylaxis after CMV disease treatment, and mTOR inhibitors for primary CMV prophylaxis were not recommended. Letermovir and marabavir are emerging CMV agents used for prophylaxis and refractory CMV disease. CMV immunoglobulins have been used to treat refractory CMV disease in Taiwan. We hope this consensus will help professionals manage patients with CMV in Taiwan to improve the quality of care.
RESUMO
INTRODUCTION: Urothelial cancers were one of the most common malignancies in patients with kidney transplants. Although radical nephroureterectomy is still the standard of care in current guidelines, studies have shown that significantly improved perioperative outcomes can be achieved for patients who underwent bilateral nephroureterectomy. Our study provides evidence on the outcome of bilateral nephroureterectomy and unilateral nephroureterectomy in kidney recipients with upper tract urothelial carcinoma. MATERIAL AND METHODS: In the study, the data of patients from a single center, Chang Gung Memorial Hospital Linkou branch, were collected retrospectively from 1981 to 2023. The patient's detailed information was collected through the medical records in the hospital. RESULTS: A total of 44 cases of kidney recipients with upper urinary tract urothelial carcinoma were collected in this study. Of the patients, 19 nephroureterectomies were performed before 2008 and 24 afterward. Incidental findings of contralateral tumors were noted in 3 out of 6 patients who underwent bilateral nephroureterectomy before 2008 and 3 out of 12 after 2008. Contralateral upper urinary tract urothelial carcinoma after unilateral nephroureterectomy was noted in 3 patients within a median of 8.1 years. The progression-free survival of bilateral nephroureterectomy was significantly better compared with a unilateral group (not reached, 15.8 years, respectively). DISCUSSION: Our study, along with previous studies, provides evidence that bilateral nephroureterectomy may be a better treatment option in kidney recipients with upper tract urothelial carcinoma. Our study has several limitations based on its retrospective nature.

PURPOSE: We observed transient elevations in creatinine levels among kidney recipients after three traditional holidays in Taiwan. This retrospective cohort study aimed to compare the changes in eGFR levels after Chinese New Year, Dragon Boat Festival, and Mid-Autumn Festival, all of which are associated with high-calorie and high-fat diets. MATERIALS AND METHODS: We conducted a retrospective analysis of 364 kidney recipients with stable graft function who were following at Chang Gung Memorial Hospital Linkou from 2018 to 2020. The graft function before and after the festival was determined by calculating the eGFR level using the serum creatinine measured during clinic visits prior to and following the festival. The patients were then categorized into subgroups based on their sex, BMI, and co-morbidities. The eGFR levels before and after the festival were evaluated and compared within these subgroups. RESULTS: A total of 301 kidney recipients have been finally included in this retrospective cohort study. The analysis showed a significant decrease in overall eGFR levels after Chinese New Year (from 56.92 ± 29.70 to 55.14 ± 24.79, P = .006), Mid-Autumn Festival (from 54.03 ± 24.61 to 53.35 ± 24.33, P = .008), and Dragon Boat Festival only in 2020 (from 50.98 ± 24.35 to 49.99 ± 23.45, P = .018). The analysis of subgroups suggested a tendency of renal function decline after all 3 traditional holidays in patient groups with DM or hypertension or nonoverweight status. CONCLUSION: In this study, we observed a significant decline in renal function among kidney recipients following traditional holidays in Taiwan, particularly among recipients with hypertension or diabetes mellitus or those who were not overweight.

BACKGROUND: New-onset diabetes after transplantation and increased insulin resistance have both been shown to affect graft performance and survival after kidney transplantation. Thus, we aimed to evaluate the predictive roles of different insulin resistance indices on early graft function in kidney transplant recipients. MATERIALS AND METHODS: We conducted a retrospective analysis of non-diabetic patients who received kidney transplantation between January 1, 2018 and December 31, 2021. The primary outcome was the predictive role of different insulin resistance indices on early graft function of serum creatinine level and estimated glomerular filtration rate at 1, 3, 6, and 12 months. The secondary outcome analyzed was the possible clinical predictive factors for poor kidney graft function at 12 months. RESULTS: Among 123 kidney transplantation patients, stratification with homeostatic model assessment for insulin resistance showed no significant difference in kidney graft function outcome at 1, 3, 6, and 12 months. However, patients with a higher insulin-to-glucose ratio exhibited a significantly higher serum creatinine level at 3 and 6 months and a significantly lower estimated glomerular filtration rate level at 3, 6, and 12 months. Using multivariate logistic regression analysis, patients with a higher insulin-to-glucose ratio were associated with a poorer kidney graft function 12 months after transplantation. CONCLUSION: Patients with a higher baseline insulin resistance with an insulin-to-glucose ratio ≥of 0.092 exhibited a significantly worse early kidney graft function. Thus, with the identification of patients with increased insulin resistance, early intervention, and preventive measures can be implemented to enhance graft performance further.

Cardiovascular disease (CVD) and its risk factors seem to be linked with deteriorated graft function and persists as the major cause of mortality in kidney transplant recipients (KTRs). Diet quality is associated with CVD prevention in the healthy population, however, less study focuses on KTRs. The study aimed to determine the association between diet quality indices and lipid profile abnormalities as risk factors for CVD in KTRs. This prospective study enrolled 106 KTRs who had functioning allografts from September 2016. Lipid profiles included low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC), and triglyceride (TG) and were based on the National Cholesterol Education Program Adult Treatment Panel III recommendations. Three-day dietary data were collected by a well-trained registered dietitian. The Alternative Healthy Eating Index-Taiwan (AHEI-Taiwan), Alternative Healthy Eating Index-2010 (AHEI-2010), and Healthy Eating Index-2015 (HEI-2015) scores were calculated and divided into quartiles and compared accordingly. KTRs' mean LDL-C, HDL-C, TC, and TG levels were 119.8 ± 36.6 mg/dL, 52.0 ± 17.9 mg/dL, 205.8 ± 43.9 mg/dL, and 160.2 ± 121.6 mg/dL, respectively. Compared with the lowest quartile, only the highest quartile of AHEI-Taiwan had lower TC and LDL-C levels. After adjustment for age, gender, energy, Charlson comorbidity index, transplant duration, and dialysis duration, logistic regression analysis revealed that the highest quartile of AHEI-Taiwan had 82% (odds ratio [OR], 0.18; 95% confidence interval [CI] 0.04-0.72, p < 0.05) lower odds of high TC and 88% (OR 0.12; 95% CI 0.03-0.58, p < 0.05) lower odds of high LDL-C, and the highest quartile of HEI-2015 had 77% (OR 0.23; 95% CI 0.05-0.95, p < 0.05) lower odds of high LDL-C. Higher adherence to a healthy diet as per AHEI-Taiwan and HEI-2015 guidelines associated with lower risk of lipid profile abnormalities in KTRs.

Several dietary indices assess the impacts of the Dietary Approaches to Stop Hypertension (DASH) diet on health outcomes. We explored DASH adherence and renal function among 85 Taiwanese renal transplant recipients (RTRs) in a cross-sectional study. Data collection included demographics, routine laboratory data, and 3-day dietary records. Three separate DASH indices, that defined by Camões (based on nine nutrients), that defined by Fung (using seven food groups and sodium), and that modified by Fung (as above but separated for men and women) were used. Renal function was ascertained through the estimated glomerular filtration rate (eGFR) from patients' medical records. Participants' mean age was 49.7 ± 12.6 years and eGFR was 54.71 ± 21.48 mL/min/1.73 m2. The three established DASH diet indices displayed significant correlations (r = 0.50-0.91) and indicated the nutritional adequacy of the diet. Multiple linear regressions indicated a significant positive association between higher DASH scores for each index and increased eGFR. In addition, RTRs in the highest DASH score tertile had higher eGFR rates than those in the lowest tertile, regardless of confounding variables. Adherence to a DASH-style diet correlated with better renal function among RTRs. Educating RTRs about the DASH diet may prevent graft function deterioration.
RESUMO
BACKGROUND: The literature has shown a significant association between body mass index (BMI) and patient and graft outcomes after renal transplantation. The purpose of this study was to reveal the effect of obesity on graft function in a Taiwanese kidney transplant cohort. METHODS: Two hundred consecutive patients who received kidney transplantation were enrolled in our study. Eight pediatric cases were excluded due to differing definitions of BMI among children. According to the national obesity criteria, these patients were divided into underweight, normal, overweight, and obese groups. Their estimated glomerular filtration rate (eGFR) was compared accordingly using t tests. Cumulative graft and patient survivals were calculated using Kaplan-Meier analysis. A P value of ≤ .05 was considered significant. RESULTS: The mean age of our cohort (105 men and 87 women) was 45.3 years. There was no significant difference comparing biopsy-proven acute rejection, acute tubular necrosis, and delayed graft function between the obese and nonobese groups (P values: .293, .787, and .304, respectively). Short-term eGFR was inferior in the overweight group, but this effect was insignificant beyond 1 month. The 1-month and 3-month eGFR were found to be correlated with BMI groups (P = .012 and P = .008, respectively) but not significant after 6 months post-kidney transplantation. CONCLUSIONS: Our study found that short-term renal function was affected by obesity and being overweight, possibly due to the higher prevalence of diabetes and dyslipidemia in obese patients and the increased surgical difficulty.

BACKGROUND: The aim of this study is to evaluate the impact of intraoperative allograft vascular flow on early kidney graft function. METHODS: A total of 159 patients underwent kidney transplantation from January 2017 to March 2022 at Linkou Chang Gung Memorial Hospital. Graft arterial and venous blood flow was measured separately with a transient time flowmeter (Transonic HT353; Transonic Systems, Inc, Ithaca, NY, United States) after ureteroneocystostomy. The early outcomes, including the postoperative creatinine level, were analyzed accordingly. RESULTS: There were 83 males and 76 females, with a mean age of 44.5 years. The mean graft arterial flow measured was 480.6 mL/min, and the mean venous flow was 506.2 mL/min. Delayed graft function (DGF) incidence was 36.5%, 32.5%, and 40.8% in total, living, and deceased donor groups, respectively. Living donor and deceased donor kidney transplantation were analyzed separately. In the DGF subgroup, there were lower graft venous flows, higher body mass index (BMI), and more male patients in the living kidney transplant group. Similarly, the deceased donor kidney transplantation group with delayed graft function tended to have higher body height, higher body weight, higher BMI, and more diabetes mellitus. The multivariate analysis showed that lower graft venous blood flow (odds ratio [OR] = 0.995, P = .008) and higher BMI (OR = 1.144, P = .042) were significantly correlated with delayed graft function in living donor kidney transplantations. In the deceased donor group, a multivariate analysis of risk factors showed that BMI had a significant correlation with delayed graft function (OR = 1.41, P = .039). CONCLUSIONS: Graft venous blood flow was significantly associated with delayed graft function in living donor kidney transplantation, and high BMI was correlated with DGF in all patients receiving kidney transplantation.

PURPOSE: Intraoperative hemodynamic instability was proven to be associated with delayed graft function (DGF) after kidney transplantation. This retrospective study aims to find the specific intraoperative hemodynamic parameters as an efficient predicting factor of DGF. MATERIALS AND METHODS: Patients who underwent kidney transplantation between 2020 and 2022 were enrolled and classified into DGF and non-DGF groups. Pediatric and multiorgan recipients were excluded. Hemodynamic parameters such as central venous pressure, mean arterial pressure, cardiac output, and cardiac index (CI) at the timings of wound incision, graft reperfusion, and operation completion were recorded, respectively. A comparison of parameters between these 2 groups was analyzed. RESULTS: We enrolled 42 recipients, with 26 in the DGF group and 16 in the non-DGF group. Compared with the DGF group, CI around graft reperfusion was significantly higher in the non-DGF group (3.97 vs 4.67 L/min/m2, P = .043). Other hemodynamic variables revealed no statistical difference. In the results of multivariate analysis, the deceased donor source, the greater volume of blood loss, and the lower CI around graft reperfusion were considered independent risk factors for DGF. Using CI around graft reperfusion to conduct a receiver operating characteristic (ROC) curve for DGF prediction, the area under the ROC curve achieved a value of 0.739 (95% confidence interval, 0.579-0.900), with the optimal cut-point value at CI = 4.245 L/min/m2. CONCLUSION: The cardiac index value around graft reperfusion was statistically associated with the incidence of DGF and might be used as a valid predicting factor.

Solid organ transplant recipients have an increased risk of tuberculosis (TB). Due to the use of immunosuppressants, the incidence of TB among solid organ transplant recipients has been consistently reported to be higher than that among the general population. TB frequently develops within the first year after transplantation when a high level of immunosuppression is maintained. Extrapulmonary TB and disseminated TB account for a substantial proportion of TB among solid organ transplant recipients. Treatment of TB among recipients is complicated by the drug-drug interactions between anti-TB drugs and immunosuppressants. TB is associated with an increased risk of graft rejection, graft failure and mortality. Detection and management of latent TB infection among solid organ transplant candidates and recipients have been recommended. However, strategy to mitigate the risk of TB among solid organ transplant recipients has not yet been established in Taiwan. To address the challenges of TB among solid organ transplant recipients, a working group of the Transplantation Society of Taiwan was established. The working group searched literatures on TB among solid organ transplant recipients as well as guidelines and recommendations, and proposed interventions to strengthen TB prevention and care among solid organ transplant recipients.

BACKGROUND: Various dietary quality indices demonstrate that a higher dietary quality score is associated with a reduced risk of several chronic diseases. However, creating an index tailored to the national population is crucial. The study investigated the association between the Alternative Healthy Eating Index-Taiwan (AHEI-Taiwan) and graft dysfunction in Taiwanese renal transplant recipients (RTRs). METHODS: A prospective cohort study recruited 102 RTRs with a functioning allograft without acute rejection in the last 3 months from September 2016 to June 2018. Laboratory data were obtained from the medical records of patients. Graft dysfunction was indicated by an estimated glomerular filtration rate (eGFR) <60 mL/min per 1.73 m2 in accordance with the Kidney Disease Outcomes Quality Initiative guideline. The dietary quality index AHEI-Taiwan was adapted from the AHEI based on Taiwanese dietary recommendations. RESULTS: Mean age, renal transplant time, and eGFR were 48.9 ± 12.8 years, 8.5 ± 5.8 years, and 54.9 ± 17.8 mL/min per 1.73 m2, respectively, in 102 RTRs. The RTRs with the highest quartile of AHEI-Taiwan scores were older and had a higher eGFR. Logistic regression analysis adjusted for age, sex, calories, Charlson comorbidity index, transplant time, and dialysis time showed that the highest quartile of the AHEI-Taiwan was associated with an 88% (odds ratio, 0.12; 95% CI, 0.03-0.59, P < .01) lower risk of graft dysfunction. CONCLUSION: A high AHEI-Taiwan score was associated with a reduced risk of graft dysfunction in Taiwanese RTRs.

PURPOSE: BK Polyomavirus (BKPyV) infection manifests as renal inflammation and can cause kidney damage. Tumor necrosis factor-α (TNF-α) is increased in renal inflammation and injury. The aim of this study was to investigate the effect of TNF-α blockade on BKPyV infection. METHODS: Urine specimens from 22 patients with BKPyV-associated nephropathy (BKPyVN) and 35 non-BKPyVN kidney transplant recipients were analyzed. RESULTS: We demonstrated increased urinary levels of TNF-α and its receptors, TNFR1 and TNFR2, in BKPyVN patients. Treating BKPyV-infected human proximal tubular cells (HRPTECs) with TNF-α stimulated the expression of large T antigen and viral capsid protein-1 mRNA and proteins and BKPyV promoter activity. Knockdown of TNFR1 or TNFR2 expression caused a reduction in TNF-α-stimulated viral replication. NF-κB activation induced by overexpression of constitutively active IKK2 significantly increased viral replication and the activity of the BKPyV promoter containing an NF-κB binding site. The addition of a NF-κB inhibitor on BKPyV-infected cells suppressed viral replication. Blockade of TNF-α functionality by etanercept reduced BKPyV-stimulated expression of TNF-α, interleukin-1ß (IL-1ß), IL-6 and IL-8 and suppressed TNF-α-stimulated viral replication. In cultured HRPTECs and THP-1 cells, BKPyV infection led to increased expression of TNF-α, interleukin-1 ß (IL-1ß), IL-6 and TNFR1 and TNFR2 but the stimulated magnitude was far less than that induced by poly(I:C). This may suggest that BKPyV-mediated autocrine effect is not a major source of TNFα. CONCLUSION: TNF-α stimulates BKPyV replication and inhibition of its signal cascade or functionality attenuates its stimulatory effect. Our study provides a therapeutic anti-BKPyV target.

The scarcity of dietary guidance for renal transplant recipients (RTRs) raises concerns regarding obesity and associated comorbidities, including impaired renal function. This two-stage cross-sectional study examined longitudinal changes in dietary nutrient intake in the same individuals over a 5-year interval. This study involved two stages: T1 (September 2016 to June 2018) and T2 (July 2022 to August 2023). The average duration between the two data collection stages was 6.17 ± 0.42 (range 5.20-6.87) years. The study included 227 RTRs with an average age and time since transplant of 49.97 ± 12.39 and 9.22 ± 7.91 years, respectively. Of the 35 patients who participated in both phases, fewer than half met the recommended intakes for energy, dietary fiber, and most vitamins and minerals, as set in the Dietary Reference Intakes (DRIs) or by the Dietitian Association Australia (DAA). Over half exceeded the DRI recommended intake for total protein, and more than 80% of the protein consumed per kilogram of body weight exceeded the DAA's recommendations. In the T2 stage, the RTRs had a significantly higher blood urea nitrogen level, lower albumin level, and estimated glomerular filtration rate. These findings indicate that deteriorating dietary intake in RTRs can adversely affect their nutritional status and transplanted kidney function over a 5-year period.

OBJECTIVES: To determine the earliest noticeable manifestation and diagnosis in patients diagnosed with tuberculosis (TB) epididymitis/epididymo-orchitis incidentally and to analyze their responses to surgical and medical treatment. METHODS: Patients who underwent surgery for the preliminary impression of chronic epididymitis/epididymo-orchitis or epididymal/testicular tumor from 2000 to 2019 were included in the study. The clinical presentations, laboratory data, radiological examinations, and operative findings were analyzed retrospectively. The outcomes were assessed by the responses to anti-TB chemotherapy and post treatment radiographic evaluations. RESULTS: All of our 25 patients with a mean age of 60.6 years were diagnosed incidentally with TB epididymitis (48.0%) and TB epididymo-orchitis (52.0%) according to the histopathological findings from their surgeries. The presence of a palpable scrotal mass (76.0%), was the major presentation. Nineteen (76.0%) patients had undergone complete chemotherapy after the surgery and 15 (78.9%) patients showed complete recovery. Four (21.1%) patients had unfavorable outcomes, 3 had TB autonephrectomies and 1 required re-surgery years after complete chemotherapy. Of the 3 (12.0%) patients who did not receive chemotherapy after their surgeries, 1 had a TB relapse in the spine and lung and 1 developed bladder cancer years later. CONCLUSION: Tuberculosis epididymitis/epididymo-orchitis is difficult to diagnose. However, some clinical clues can assist including aged patients, extragenital TB histories, poor responses to antibiotic treatment and scrotal skin lesion. Complete anti-TB chemotherapy is mandatory even after the total removal of TB lesion. Supplemental surgical interventions can be considered when the symptoms are not relieved after chemotherapy. Lifespan follow-up is recommended due to high relapse rate.

Background: This study investigated the association between dietary quality indices and recurrent chronic kidney disease (rCKD) in Taiwanese post-renal transplant recipients (RTRs). Methods: This prospective study recruited RTRs aged >18 years with a functioning allograft and without any acute rejection in the past 3 months from September 2016 to June 2018. Dietary quality indices included the Alternative Healthy Eating Index (AHEI) and AHEI-2010, and the Taiwanese version of the AHEI (AHEI-Taiwan) was calculated using 3-day dietary records, and calculated scores were divided into quartiles. Laboratory data were collected from medical records. rCKD was defined as an estimated glomerular filtration rate (eGFR) of <60 mL/min/1.73 m2. Logistic regression analysis was performed to analyze the associations. Results: This study included 102 RTRs. The RTRs with higher AHEI, AHEI-Taiwan, and AHEI-2010 scores were older and had higher eGFRs and lower odds of rCKD. As compared with the lowest quartile, patients with the highest quartiles of the AHEI [odds ratio (OR), 0.10; 95% confidence interval (95% CI): 0.02, 0.49; p-trend = 0.004), AHEI-2010 (OR, 0.17; 95% CI: 0.04, 0.72; p-trend = 0.016], and AHEI-Taiwan (OR, 0.13; 95% CI: 0.03-0.59; p-trend = 0.008) had lower odds of rCKD, respectively. As compared with the lowest quartile, patients who consumed the highest quartiles of red and processed meat had 11.43 times higher odds of rCKD (OR, 11.43; 95% CI: 2.30-56.85; p for trend <0.01). Conclusion: Higher dietary quality indices are associated with lower odds of rCKD in Taiwanese RTRs. Particularly, a positive association between a higher intake of red meat and processed meat and higher odds of rCKD remained exists after transplantation in Taiwanese RTRs. Further dietary guidelines and individualized dietary education were necessary for RTRs to prevent graft function deterioration.
RESUMO
Cardiovascular disease (CVD) is the leading cause of mortality in post-renal transplant recipients (RTRs). Adequate nutrient intake is a protective factor for CVD. We examined the associations of macronutrients and micronutrients with traditional and nontraditional CVD risk factors. Conducted from September 2016 to June 2018, this cross-sectional study included 106 RTRs aged ≥18 years with a functioning allograft. Dietary intake data from 3-day dietary records were collected. Nutrient intake adequacy was defined using various instruments, including the National Kidney Foundation Kidney Disease Outcomes Quality Initiative (K/DOQI) guidelines. CVD risk factors were defined according to the K/DOQI guidelines. Bivariate and multivariate logistic regression models were used to analyze the associations. CVD risk was present in all patients; the lowest proportions of adequate intake were 2.8% for dietary fiber and 0.9% for calcium. Adequate nutrient intake was associated with a lower likelihood of the occurrence of traditional CVD risk factors (specifically, 1.9-31.3% for hyperlipidemia and 94.6% for diabetes mellitus). It was also associated with a lower likelihood of the occurrence of nontraditional CVD risk by 0.8% for hypophosphatemia and 34% for hyperuricemia. Adherence to dietary guidelines should be promoted among RTRs to decrease CVD risk.

Over-immunosuppressed kidney transplant recipients are susceptible to malignancies and BK polyomavirus (BKPyV)-associated nephropathy (BKPyVAN). This study aimed to verify the association between BKPyV infection and urinary tract cancers (UTC). A total of 244 kidney transplant recipients were enrolled at Chang Gung Memorial Hospital from June 2000 to February 2020. Biopsy-proven BKPyVAN patients (n = 17) had worse kidney function (eGFR: 26 ± 13.7 vs. 47.8 ± 31.0 mL/min/1.73 m2). The 5-year allograft survival rates for patients with and without BKPyVAN were 67% and 93%, respectively (p = 0.0002), while the 10-year patient survival was not different between the two groups. BKPyVAN patients had a significantly higher incidence of UTC compared to the non-BKPyVAN group (29.4% vs. 6.6%). Kaplan-Meier analysis showed that the UTC-free survival rate was significantly lower in BKPyVAN patients, and the onset of UTC was significantly shorter in BKPyVAN patients (53.4 vs. 108.9 months). The multivariate logistic regression analysis demonstrated that age (RR = 1.062) and BKVAN (RR = 6.459) were the most significant risk factors for the development of UTC. Our study demonstrates that BKPyVAN patients have greater allograft losses, higher incidence, a lower cancer-free survival rate, and an earlier onset with a higher relative risk of developing UTC compared to non-BKPyVAN patients.

PURPOSE: Healthcare professionals play an important role in the organ donation process. The aim of this study was to examine the organ donation registration rate and related factors among clinical nurses. MATERIAL AND METHODS: In this cross-sectional, correlational study, we used mailed questionnaires to collect data from four geographical areas and three hospital levels in Taiwan from June 6 to August 31, 2018. Two thousand and thirty-three clinical nurses participated in this study. RESULTS: Participants' mean age was 34.47 years, and 95.7% were women. Of them, 78.3% were willing to donate their organs and 20.6% had registered for organ donation after death. The results of logistic regression showed that in the personal domain, higher age (odds ratio (OR) = 1.03, p < 0.001), better knowledge of organ donation (OR = 1.09, p < 0.001), and a positive attitude toward organ donation (OR = 2.91, p < 0.001) were positively associated with organ donation registration, while cultural myths (OR = 0.69, p < 0.001) were negatively correlated. In the policy domain, the convenience of the registration procedure (OR = 1.45, p < 0.001) was positively associated with registration. A gap between willingness to donate and actual registration was observed. CONCLUSIONS: Personal factors played an important role in organ donation registration. Therefore, efforts to improve knowledge and inculcate positive cultural beliefs about organ donation among clinical nurses are recommended. There is also a need to cooperate with government policies to provide appropriate in-service training and policy incentives and establish an efficient registration process.

This study investigated how multiple family members co-construct the ethical significance of living donor liver transplantation (LDLT) and how the family structure and dynamics of donor-recipient-caregiver relationships shape the communication and decision-making process within the sociocultural context of Taiwan. We conducted in-depth interviews with 36 participants from 13 families at the Chang Gung Memorial Hospital from February to December 2019. Interviews were audio recorded, transcribed, and translated from Mandarin to English and analyzed utilizing grounded theory and thematic analysis. Our findings revealed that LDLT in Taiwan is not merely a personal choice of either donor or recipient but essentially a collaborative process of family-centered medical decision-making, intertwined with socioeconomic conditions, cultural and social norms, gender roles, and the division of labor in the household. The notion of reciprocity and indebtedness for family members is a central theme underlying the entire process of motivation, deliberation, and decision-making, thereby reinforcing the naturalness of LDLT. However, our study highlighted that donors from families with traditional gender hierarchy and power imbalance may experience psychological and social vulnerabilities. Conclusively, we suggest that healthcare professionals should be sensitive to the contextual and relational factors involved in family dynamics and provide appropriate support to the ambivalent donors.

OBJECTIVES: Organ allocation is of decisive importance in the current situation of organ shortage. The aim of this study is to compare the long-term graft outcomes of deceased donor recipients before and after the new nationwide allocation system in Taiwan. METHODS: From April 1, 2000 to March 31, 2010, 181 deceased kidney transplantations were reviewed retrospectively, and recipients were divided by the enforcement day (April 1, 2005) of nationwide allocation into group 1 (before) and group 2 (after). Baseline demographics were reviewed. Outcomes, including graft survival (GS) and patient survival, at 1-, 3-, 5-, and 10-years after transplantation were analyzed. RESULTS: The baseline demography was similar between the 2 groups except that group 1 is younger. Group 2 has less HLA-B (P < .001) and HLA mismatches (P = .005). There were significantly more 0-mismatch recipients in group 2 (6 vs 27, P = .001), as well as extended criteria donor (ECD) recipients (0 vs 7). Group 2 has less optimal 1-year GS (95.6% vs 86.8%, Log-Rank P = .037), which becomes nonsignificant at 3-, 5-, and 10-years after transplantation. By excluding ECD recipients, the GS were similar at all time. There was no difference in patient survival between the 2 groups. CONCLUSION: The new nationwide allocation system provided us more 0-mismatch kidneys. The nationwide scheme remains beneficial to kidney recipients after the acute adverse effects of ECD and aging vanish.
