Importance If the success of Descemet membrane endothelial keratoplasty (DMEK) is not affected by whether the donor has diabetes, then the donor pool should expand. Objective To determine whether the 1-year DMEK success rate is affected by the presence of diabetes in the donor. Design, Setting, and Participants This was a multicenter, double-masked, randomized clinical trial conducted from February 2022 to July 2025 at 28 clinical sites (46 surgeons), with donor corneas provided by 13 eye banks in the US. Included in the study were individuals undergoing low to moderate risk DMEK (95% for Fuchs endothelial corneal dystrophy). Study data were analyzed from April to September 2025. Intervention DMEK performed with a cornea from a donor without or with diabetes, assigned using a minimization procedure (comparable with randomization) to achieve an approximate 2:1 distribution, respectively. Main Outcomes and Measures Graft success at 1 year Results A total of 1097 individuals (1421 study eyes; median [IQR] age, 71 [66-76] years; 631 female [57.5%]) were included in the study. The 1-year cumulative probability of graft success was 96.3% (95% CI, 95.0%-97.5%) among 912 study eyes (64.2%) receiving tissue from donors without diabetes and 97.1% (95% CI, 95.5%-98.4%) among 509 study eyes (35.8%) receiving tissue from donors with diabetes (difference between groups = 0.7 percentage points; 95% CI, −1.2 to 2.6; P = .63). The 1-year cumulative probability of graft success was 96.5% (95% CI, 93.6%-98.9%) in the mild donor diabetes severity subgroup (n = 173) and 97.3% (95% CI, 95.4%-98.8%) in the moderate to severe donor diabetes severity subgroup (n = 336), using a diabetes severity rating scale based on medical history. The rates of primary donor failure, early failure related to surgical complications, and subsequent failure were as follows: 2.5% (23 of 912), 0.7% (6 of 912), and 0.3% (3 of 912), respectively, in recipients of tissue from a donor without diabetes, and 2.6% (13 of 509), 0.4% (2 of 509), and 0%, respectively, among recipients of tissue from a donor with diabetes. There were no failures due to graft rejection. Conclusions and Relevance The 1-year success rate in eyes undergoing DMEK with successfully prepared tissue was very high regardless of donor diabetes status. These results, supported by the separately reported finding that endothelial cell loss and cornea morphometry after 1 year were not affected by donor diabetes status, provide strong support for having no restrictions on the use of tissue from donors with diabetes for DMEK.

Background & Aims: The clinical course and outcomes of alcohol-associated hepatitis (AH) remain poorly understood. Major adverse liver outcomes do not capture the added risk of return to drinking. We examined the natural history of AH and developed a composite endpoint using a contemporary observational cohort of AH. Approach & Results: A cohort of 1127 participants: 712 AH patients, 256 heavy drinking controls without clinically evident liver disease, and 159 healthy controls, were prospectively followed for 6 months at 8 United States centers as part of the Alcoholic Hepatitis Network (AlcHepNet) consortium. Outcomes included mortality and a composite endpoint (AlcHepNet composite index) that included death, liver transplantation, hepatic decompensation (new onset/worsening ascites, HE, variceal bleeding), liver-related hospital admission, MELD increase ≥5, and return to drinking. Of 712 AH patients (age 45±10.7 y; 59.1% male), 558 (79.0%) had severe and 148 (21.0%) had moderate AH, 232 (32.5%) died, and 86 (12.1%) underwent liver transplantation. Mortality rates in moderate AH and severe AH were 0.7% versus 17.2% (30 d), 3.4% versus 26.5% (90 d), and 8.8% versus 30.5% (180 d), respectively (all p <0.001). Composite liver/alcohol use events were noted in 459 (64.5%) AH patients. Higher MELD score, lower mean arterial pressure, and baseline leukocytosis were associated with higher 90-day mortality in AH (all p <0.05). College education and higher ALP were associated with lower mortality. Heavy drinking controls had low mortality (n=3; 1.2%). Conclusions: This large observational study showed a high incidence of composite liver and alcohol-use events within 6 months, reiterating the need for early interventions.

AbstractThe goal of national interoperability is to improve care quality and decrease administrative burden and costs. Patients, providers, and other stakeholders are increasingly concerned that indiscriminate sharing of data may have deleterious, permanent consequences, as well as fail to provide granular control over the sharing of individual health data. Data segmentation and consent standards to date have been limited in scope and implementation, which has hindered efforts to scale data sharing preferences. Shift, an independent expert stakeholder task force, has been convened to mature standards, terminologies, and consensus-driven implementation guidance, which are prerequisites for more robust policy drivers needed to support nationwide sensitive data segmentation and consent capabilities. This paper describes Shift's framework and processes as means to advance equitable interoperability.

Abstract Background and Aims The TRISCEND II trial demonstrated superior clinical benefits for patients with ≥severe tricuspid regurgitation (TR) treated with the EVOQUE transcatheter tricuspid valve replacement (TTVR) system plus medical therapy vs medical therapy alone. This work reports 1-year and 18-month outcomes in patients stratified by baseline TR severity. Methods The multicentre, prospective TRISCEND II trial enrolled 400 patients with symptomatic, ≥severe TR, and randomized 2:1 to TTVR (n = 267) or control (n = 133). In a post hoc analysis, patients were stratified into severe TR (n = 172) and massive/torrential TR (n = 220) cohorts. Clinical and quality-of-life outcomes were reported at 1 year, with Kaplan–Meier estimates for all-cause mortality and heart failure (HF) hospitalization assessed at 18 months. Study oversight included an independent echocardiographic core laboratory, clinical events committee, and data safety monitoring board. Results One year after TTVR, TR was ≤mild in 95.2% of severe TR and 95.3% of massive/torrential TR patients. The primary safety and effectiveness endpoint (win ratio) favoured TTVR over control regardless of baseline TR severity: severe {1.64 [95% confidence interval (CI): 1.11, 2.43]} and massive/torrential [2.20 (1.55, 3.14)]. At 18 months, TTVR patients had similar mortality to controls [rate difference: severe 0.2% (−11.6, 11.9), massive/torrential −5.8% (−17.6, 6.0)], whereas HF hospitalization rates favoured TTVR in the massive/torrential cohort [vs control, severe 9.8% (−3.0, 22.7), massive/torrential -15.2% (−28.9, −1.5)]. Conclusions Patients with ≥severe TR benefit from TTVR, experiencing improvements in TR severity, functional capacity, and quality of life regardless of baseline TR severity, with a signal for greater benefit in patients with more advanced disease.

Background: How parental alcohol use disorder and liver disease-related mortality influence the risk and the outcomes of alcohol-associated hepatitis (AH) in the offspring is unknown. Methods: We analyzed data from 2 prospective observational studies of AH cases and heavy drinking controls (HDCs). Family history of parental alcohol use disorder and liver disease mortality was assessed at the study entry. Logistic regression and Cox proportional hazard models were used to assess the influences of family history on AH development and outcome. Results: Data from 1356 participants in two prospective cohorts (926 AH cases and 430 HDC) were combined and analyzed. Parental alcohol use disorder was found in 56.9% of AH cases and 61.1% of HDC; parental death due to liver disease was reported in 7.5% of AH cases and 5.7% of HDC. Multivariable logistic regression showed that parental liver disease-related mortality was associated with more than a doubled risk of AH development in the offspring after controlling for their demographic characteristics and drinking behavior (OR=2.26, 95% CI: [1.22, 4.20]). Moreover, among the AH cases, having a parent die of liver disease significantly increased the 90-day mortality of study participants after adjusting for the effects of other risk factors (HR=2.26, 95% CI: [1.05, 4.86]). Conclusions: The study highlights the influences of parental death due to liver disease on AH development and mortality. Identifying patients at risk of AH through family history might help facilitate discussions on reducing alcohol consumption.

ABSTRACTPatients with vascular anomalies (VAs) require expert multidisciplinary care. No prior studies have characterized the sociodemographic characteristics across multiple VA centers. We collected data on 5783 patients receiving care at 20 VA centers between July 1, 2020 through December 31, 2022. Male patients were underrepresented compared to the state‐level census data at 17/20 centers. Black and Asian patients were underrepresented at 14/20 and 12/20 centers, respectively. The median distance to the hospital was 48 miles, and median age was 12.0 years. These data suggest that race, sex, age, and distance from the hospital could impede the ability to access expert VA care.

Abstract In 2003, the Institute of Medicine noted the need to improve workforce diversity. The American Society of Hematology (ASH) responded by developing the Minority Recruitment Initiative (MRI) to recruit diverse physicians/scientists into hematology. We evaluated the outcomes of the program. From 2004 to 2022, there were 405 awardees. Compared with national estimates, MRI awardees were less likely to discontinue their degree programs. MRI graduate student awardees had 0% attrition (97.5% confidence interval [CI], 10.6), whereas the national minority graduate student attrition was 36%. Medical student awardees had 2.2% (95% CI, 0.61-5.6) attrition, compared with the minority medical school attrition of 5.6%. Awardees were more likely than expected to pursue hematology-oncology (5.7% minority national estimate) because 14.4% (95% CI, 8.1-23.0) of medical student awardees and 88.5% (95% CI, 70.0-97.6) of early career awardees remain in the field. ASH has developed a successful program, but continued efforts are needed to advance equity in hematology.
