Living donor liver transplantation (LDLT) is a life-saving procedure for patients with end-stage liver disease. As its use expands worldwide, ensuring the safety and well-being of live liver donors (LLD) is of paramount importance. Published evidence on early postoperative complications after living donor hepatectomy—those occurring within 90 days of surgery—is limited, and standardized postoperative care protocols are lacking. The International Liver Transplantation Society (ILTS) and the International Living Donor Liver Transplantation Group (iLDLT Group) convened a consensus conference in Toronto in March 2025 to develop guidelines for the safe care of the LLDs. This manuscript details the recommendations on early postoperative considerations for the safety of LLDs developed by Working Group III (WGIII) of the Consensus Scientific Committee, using the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system for assessment of recommendations, and the Danish model of consensus. WGIII addressed four key areas: (1) standardized postoperative care, (2) early biliary complications, (3) early postoperative liver dysfunction, and (4) early postdischarge follow-up. This report emphasizes the need for vigilant postoperative monitoring in specialized units, with access to experienced providers and defined clinical pathways. Structured clinical and psychosocial follow-up protocols, perioperative prophylaxis for surgical site infections and venous thromboembolism, and management of early biliary and vascular complications are discussed. These may help standardize care, reduce complications and improve short-term outcomes in LLDs.

Living liver donation is a critical component for addressing organ shortage and improving outcomes for patients with end-stage liver disease. As the prevalence of living donor liver transplantation (LDLT) increases worldwide, understanding and optimizing long-term donor health is paramount. The 2025 International Liver Transplantation Society and International Living Donor Liver Transplantation Society (ILTS-iLDLT) Consensus Conference convened experts in the field of liver transplantation to establish evidence-based guidelines focused on the long-term medical, psychological, and social considerations following living liver donation. The aim of this working group was to integrate current evidence and expert consensus on donor follow-up protocols, risk assessment, and management strategies to promote long-term donor health, quality of life, and living liver donor programs globally to safeguard the welfare of this unique population.

Abstract The cortical asymmetry index evaluates the cortical thickness asymmetry between hemispheres. We investigated cortical asymmetry index in asymptomatic and symptomatic mutation carriers of autosomal dominant Alzheimer’s disease to explore the brain asymmetry within the Alzheimer’s disease continuum. Sixty baseline T1-weighted MRI scans were obtained from the Clinic Barcelona cohort. Baseline and longitudinal MRI data from 564 participants within the dominantly inherited Alzheimer network observational study were used as an independent, confirmatory cohort. Cerebrospinal fluid and plasma neurofilament light chain levels were included when available. Cortical thickness was calculated using Freesurfer and cortical asymmetry index was calculated via an open-source pipeline. Cross-sectional analyses examined cortical asymmetry index differences based on clinical classification and APOE ε4 status, adjusting for age, sex and estimated years from onset, while correlations were assessed with age, estimated years from onset, mini-mental state examination scores, and neurofilament light. Longitudinal cortical asymmetry index evolution was modelled using generalized additive models in the dominantly inherited Alzheimer network observational study cohort, incorporating age, sex, and the interaction between group and estimated years from onset. The cortical asymmetry index successfully distinguished asymptomatic mutation carrier and symptomatic mutation carriers from healthy controls in the Clinic Barcelona cohort and symptomatic mutation carriers from controls in dominantly inherited Alzheimer network observational study. Higher cortical asymmetry index in mutation carriers (asymptomatic mutation carrier and symptomatic mutation carriers combined) and in symptomatic mutation carriers were associated with higher plasma neurofilament light levels, a closer proximity to symptom onset, and lower mini-mental state examination in the Clinic Barcelona cohort. In the dominantly inherited Alzheimer network observational study cohort, mutation carriers exhibited increased cortical asymmetry index compared to controls and correlated with elevated neurofilament light (plasma and Cerebrospinal fluid), lower mini-mental state examination, and a closer proximity to symptom onset. APOE3/3 carriers showed greater asymmetry than other APOE genotypes and significant cortical asymmetry index differences between asymptomatic mutation carrier and symptomatic mutation carriers. Longitudinally, cortical asymmetry index increased over time significantly in symptomatic mutation carriers. These findings underscore brain asymmetry as a potential biomarker for early Alzheimer’s disease progression in autosomal dominant Alzheimer’s disease, with implications for detection and monitoring tracking disease-related neuroanatomical changes.

An ST-segment elevation myocardial infarction is a life-threatening condition within the spectrum of acute coronary syndrome, with well-recognized implications for short-term and long-term health outcomes. Retrospective review of our institutional electronic health records identified patterns of inaccurate acute coronary syndrome diagnostic assignment, including the presence of erroneous ST-segment elevation myocardial infarction diagnoses in discharge records. Such erroneous diagnoses in the durable health record may increase risk to patients through inadequate risk assessment and inappropriate follow-up care. Misapplication of a shortcut in our electronic health record system for rapidly ordering emergent cases was identified as a potential cause of the quality gap. To address this issue, a nurse-led quality improvement project was developed by using the define, measure, analyze, improve, and control framework. The project intervention decreased the percentage of patients with erroneous diagnoses from 24% to 7% and marginally improved nursing staff satisfaction. Our project successfully addressed an institutional quality concern. Our goal of reducing erroneous discharge diagnoses with minimal disruption to our existing practice was achieved, positively affecting our patients. Including both nurse leaders and frontline health care workers ensured the success of our project.

Background: Among the 1.5 million cases of cutaneous squamous cell carcinoma (cSCC) diagnosed annually in the United States, a subset of aggressive tumors recur or metastasize. Treatment options include total margin-controlled surgery, such as Mohs micrographic surgery or other forms of peripheral and deep en face margin assessment (MMS/PDEMA), and standard excision with postoperative vertical section margin assessment (SEVMA). NCCN Guidelines recommend MMS/PDEMA for the management of cSCC classified as very high risk based on NCCN risk stratification criteria. This study aims to validate the recommendation of MMS/PDEMA as the preferred surgical approach for NCCN very high-risk cSCCs, using data from a multicenter, multinational cohort. Methods: A multicenter cohort study was conducted across 12 sites, including 10 in the United States, 1 in Spain, and 1 in Brazil, comprising 2,752 primary NCCN very high-risk cSCCs treated with MMS/PDEMA or SEVMA. Propensity score–weighted analysis was used to balance baseline characteristics. Outcomes included local recurrence (LR), nodal metastasis (NM), distant metastasis (DM), and disease-specific death (DSD). Results: After balancing baseline characteristics, SEVMA was associated with a 2-fold higher rate of poor outcomes, including recurrence, metastasis, and DSD, compared with MMS/PDEMA. The 3-year cumulative incidence of poor outcomes was higher for SEVMA: LR (12.5% vs 5.9%), NM (11.6% vs 6.0%), DM (4.3% vs 1.9%), and DSD (6.2% vs 3.3%). Conclusions: This study supports the NCCN recommendation of MMS/PDEMA for NCCN very high-risk cSCC, showing reduced recurrence, metastasis, and cSCC-specific mortality compared with SEVMA.

Objective: To evaluate the ethical implications, clinical benefits, and challenges associated with centralizing the surgical care of vestibular schwannoma (VS) care. Databases reviewed: PubMed, Embase, CINAHL, Web of Science, Cochrane, Scopus. Methods: A scoping review was conducted per the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews) guidelines. A comprehensive search of 6 electronic databases yielded 1,231 articles using keywords related to vestibular schwannoma, centralization of care, centers of excellence, and ethical considerations. After removing duplicates (n=344) and screening titles and abstracts (n=887), 17 full-text articles were reviewed. Two additional articles were identified through manual screening. A total of 15 studies were included in the final analysis. Results: Hospitals were categorized by surgical case volume (high, medium, low) to compare patient demographics and clinical outcomes. Patients seen at low-volume hospitals (LVHs) were generally older and more racially diverse, and more likely to have public insurance (Medicare or Medicaid), whereas high-volume hospitals (HVHs) served a younger, predominantly White, and privately insured population. Of the 14 studies evaluating outcomes, 12 demonstrated a positive association between higher surgical volume and improved outcomes, including reduced complications, lower mortality, shorter length of stay, and decreased hospitalization costs. High-volume hospitals also had significantly higher rates of routine discharge. Conclusion: Centralization of vestibular schwannoma care to high-volume centers is associated with improved clinical outcomes and reduced health care costs. However, these benefits must be carefully weighed against potential ethical concerns, including disparities in access related to socioeconomic status, insurance coverage, and geographic location.

BACKGROUND AND OBJECTIVES: Stereotactic radiosurgery (SRS) for brain arteriovenous malformations (AVMs) can cause radiation-induced changes (RIC), but its interactions with AVM embolization are not well established. The aim of this study was to assess the effect of previous embolization on RIC in SRS-treated AVM patients. METHODS: Data of AVM patients treated with single-session SRS from 1987 to 2018 were retrieved from the International Radiosurgery Research Foundation. Univariable and stepwise backward logistic regression models were used to identify RIC predictors. Patients were stratified into those who received pre-SRS embolization (E + SRS) vs those who did not (SRS-only). Radiologic RIC (rRIC) was the primary end point. Secondary outcomes included symptomatic RIC (sRIC) and permanent symptomatic RIC (pRIC). RESULTS: Among 1187 AVM patients, the mean age was 36.4 years (SD 16.8), with 50.4% female patients. AVMs had a mean untreated AVM volume of 5.2 cm 3 . A total of 130 patients (11%) underwent neoadjuvant embolization (E + SRS). The overall rRIC and sRIC rates were 32.8% and 12.1%, respectively, with time to rRIC and sRIC being significantly longer in the E + SRS vs SRS-only cohorts (103.6 ± 339.4 vs 11.3 ± 12.5 and 60.4 ± 262.9 vs 9.5 ± 9.0 months, respectively). Seizures at presentation and ≥3-cm untreated AVM volume significantly correlated with a higher likelihood of rRIC (adjusted odds ratio [aOR] 2.32 [1.25-4.30] and aOR 2.77 [1.24-6.16], respectively). Age and pre-SRS embolization were associated with a significantly lower risk of rRIC (aOR 0.97 [0.96-0.99] and aOR 0.32 [0.13-0.74], respectively). The E + SRS cohort had significantly reduced odds of rRIC (aOR = 0.37 [0.15-0.89]) and pRIC (aOR = 0.04 [0.00-0.30]) after adjusting for significant covariates. CONCLUSION: Seizures at presentation and larger untreated AVM volume were independently associated with an increased risk of rRIC, whereas older age and pre-SRS embolization were protective. Notably, patients who underwent embolization before SRS had lower odds of rRIC and pRIC, with delayed onset of complications compared with SRS-only.
