MATERIAL AND METHODS We performed a retrospective 20-year observational follow-up study subsequent to a prior prospective study to evaluate the long-term outcomes following ligation of the proximal left renal vein (LRV). Between October 2001 and January 2005, 44 liver cirrhosis patients underwent LDLT with LRV ligation. These patients were followed up until April 2024 or patient death. RESULTS Portal flow was significantly increased after LRV ligation. Renal function recovered uneventfully after LDLT in 40 patients. Eighteen patients died due to cancer recurrence (n=6), pneumonia (n=3), and other causes (n=9), thus 1-, 5-, 10-, and 20-year overall patient survival rates were 95.5%, 86.4%, 81.8%, and 59.1%, respectively. Solitary atrophy of the left kidney was not observed. SSRS was completely resolved in 20 patients, but the other 20 patients showed persistently identifiable SSRS of variable extents to date or at patient death. The LRV was reopened to make large SSRS in another 4 patients, in which retrograde transvenous obliteration was performed in 2 for variceal bleeding control and in another 2 for portal flow augmentation. CONCLUSIONS This study demonstrated that LRV ligation is a safe and effective method to control SSRS. Currently, direct ligation of the SSRS is preferred, but LRV ligation still can be a good therapeutic option when direct access to SSRS is not feasible.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947492"},"PeriodicalIF":1.1,"publicationDate":"2025-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143802310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patient pharmacokinetic variability poses challenges in dose adjustment. This study aimed to evaluate tacrolimus dosing optimization using machine learning and statistical methods. MATERIAL AND METHODS We conducted a retrospective study of 749 kidney transplant recipients at Seoul St. Mary's Hospital between January 2015 and December 2019. Data on tacrolimus doses, trough levels, and other clinical variables were collected and analyzed during the first 12 postoperative days of hospitalization. Three approaches were evaluated: Extreme Gradient Boosting (XGBoost), Elastic Net regression (EN), and Linear regression (LR). The models were trained and validated using 5-fold cross-validation, with performance assessed using R² errors and alignment with clinically acceptable error margins. RESULTS Elastic Net showed the best performance with R² (Coefficient of Determination) of 0.861±0.044 and RMSE (Root Mean Square Error) of 0.930±0.220. Linear Regression and XGBoost provided clinically relevant predictions but with slightly lower accuracy. External validation was not performed, limiting the generalizability of the results. CONCLUSIONS The Elastic Net is a practical and reliable model for predicting the optimal tacrolimus dose. Machine learning and statistical methods are useful tools for optimizing tacrolimus dosing during hospitalization after kidney transplantation. Future studies should incorporate multi-center validation to improve clinical applicability.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947768"},"PeriodicalIF":1.1,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11971949/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143750497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although LDLT is restricted to donors with altruistic motivations, some still experience post-donation regret. However, the role of family-related motivation in post-donation regret remains underexplored. This study examined whether family-related motivations were associated with regret intensity and whether these associations varied by the type of family relationship (child vs spouse, sibling, or parent donors). MATERIAL AND METHODS This study was a cross-sectional secondary analysis. The sample comprised 124 postoperative living liver donors. They completed a family-related motivation subscale of the Donor Motivation Questionnaire and a single-item measure of regret intensity. For moderation analysis, Model 1 of the PROCESS macro was used. RESULTS The mean score of post-donation regret was 1.3 out of 4. Non-child donors reported higher levels of regret than child donors. Particularly in non-child donors, family-related motivation was inversely associated with regret intensity, after adjusting for age, sex, caregiver role, postoperative complications, and months since donation. CONCLUSIONS These findings suggest that child and non-child donors have distinct motivations, which are linked to differing levels of regret. Accordingly, transplant teams should provide tailored information and support services based on the donor's family relationship type.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e947414"},"PeriodicalIF":1.1,"publicationDate":"2025-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11954405/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143699370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pulmonary embolism (PE) is an unpredictable but serious complication following liver donor hepatectomy (LDH), contributing significantly to postoperative morbidity and mortality. CASE REPORT This article reports 4 cases of PE in living donors following LDH, discussing their clinical presentations, diagnosis, and treatment, and reviewing the relevant literature. Patient 1 was a 46-year-old man who underwent laparotomy right hepatectomy and developed PE on postoperative day (POD) 2. Patient 2 was a 42-year-old woman who donated the left half liver for her son. On POD 8, she was diagnosed with PE by enhanced computed tomography (CT) scan. Patient 3 was a 65-year-old man with 2 years history of hypertension. He underwent a laparotomy right hepatectomy and developed PE on POD 2. Patient 4 was a 57-year-old woman who underwent laparotomy left hepatectomy with the middle hepatic vein. On POD 3, the patient suddenly developed dyspnea after ambulation, and the enhanced CT of pulmonary arteries showed extensive PE in both lungs. All donors developed symptoms such as dyspnea and hypoxemia postoperatively, and were diagnosed with PE through imaging studies. Prompt anticoagulation therapy led to favorable outcomes in all cases. CONCLUSIONS Although PE is a rare and serious complication after LDH, early recognition and timely intervention are crucial to prevent catastrophic outcomes for the donor. Improving perioperative management is key to enhancing donor safety.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e946752"},"PeriodicalIF":1.1,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11846252/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143439681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dosing is reduced by 30% (Mel140) in frail patients. Studies comparing the performance of these regimens report inconsistent findings, mainly confounded by non-consecutive patient inclusion, missing data, and heterogenous practices. The largest study reported an increased risk of death with Mel200 among patients with very good partial remission, or better, before ASCT. This retrospective study from a single center compared outcomes of patients with a first ASCT for myeloma treated with melphalan 140 mg/m² or 200 mg/m². MATERIAL AND METHODS This was a retrospective real-world analysis from a single center. Data from 159 consecutive, first, single ASCTs for MM between 2012 and 2021 were included. Mel200 and Mel140 were administered to 131 and 28 patients, respectively. Primary and secondary objectives were overall survival (OS) and progression-free survival (PFS), respectively. RESULTS Median follow-up was 5.8 years. Over 90% received bortezomib-based induction, and over 76% achieved at least very good partial remission (VGPR) before ASCT in either group. PFS estimates were similar between groups (P=0.49). OS was longer with Mel200 (HR=0.42, P=0.002). Mel200 maintained OS superiority in all relevant subgroups. CONCLUSIONS In a homogenous population of patients with MM, Mel200 was associated with longer OS, likely reflecting the physiological state of patients and tolerance to subsequent treatments.

Besides synthetic toxins, natural toxins such as phallotoxin from Amanita phalloides mushrooms also lead to severe hepatocyte damage. This study investigates the outcomes of liver transplantation (LT) as a life-saving intervention in patients suffering from ALF due to acetaminophen and Amanita phalloides poisoning. MATERIAL AND METHODS We conducted a retrospective analysis of 39 patients who underwent LT for ALF induced by acetaminophen (n=18) or A. phalloides (n=21) poisoning at the Medical University of Warsaw. Various statistical analyses, including logistic regression, Mann-Whitney-U, and chi-squared tests, were employed. Survival rates were determined using Kaplan-Meier analysis. RESULTS The cohort included 24 females and 15 males, with a median age of 41. The 90-day mortality rate was 22.2% for acetaminophen poisoning and 38.1% for A. phalloides poisoning (P=0.284), with an estimated 5-year survival rate of 59.6%. Key factors associated with increased 90-day mortality included the number of red blood cells transfused (OR 1.574 per unit; P=0.011), fresh frozen plasma units (OR 1.346 per unit; P=0.003), acute kidney failure requiring hemodialysis (OR 13.50; P=0.021), and days from listing to LT (OR 2.289 per day; P=0.013). CONCLUSIONS Liver transplantation for ALF, though inherently high-risk, offers substantial survival benefits. Outcomes are largely influenced by the patient's condition at the time of transplant, organ availability, and intraoperative management.

RESULTS The risk factors for severe infection were as follows: Moderate IgG hypogammaglobulinemia (IgG <600 mg/dL at days 7 or 30, HR 2.07, 95% CI 1.37-3.12, p=0.0005, 2 points), CD4 <400 cells/uL at day 30 (HR 1.76, 95% CI 1.03-3.04, p=0.039, 2 points), C3 <80 mg/dL at day 30 (HR 2.18, 95%CI 1.16-4.06, p=0.014, 2 points), and CRP >3 mg/dL at day 30 (HR 2.11, 95% CI 1.12-3.97, p=0.02, 2 points). In patients with ≥4 points, the HR for infection was 5.18 (95% CI 3.06-8.75; p<0.001). RIS2020 was an independent predictor of severe infection in multivariate models. CONCLUSIONS An immunological score combining moderate IgG hypogammaglobulinemia and other parameters of innate and acquired immunity could better identify the risk for severe infection in SOT.","PeriodicalId":7935,"journal":{"name":"Annals of Transplantation","volume":"30 ","pages":"e946233"},"PeriodicalIF":1.1,"publicationDate":"2025-01-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11760188/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142998752","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
