Importance Currently, there are no standardized outcome domains or measures in clinical trials for facial aging. Heterogeneity in outcome domains and measurement instruments across clinical trials creates difficulty in directly comparing interventions, determining superior therapies, and developing high-quality meta-analyses. Objective To develop a core outcome set (COS) of essential domains to be reported in clinical trials evaluating the efficacy of interventions for facial aging. Evidence Review PubMed/Medline, Embase, Cochrane Central Register of Controlled Trials, and CINAHL were searched from September 2005 to September 2015. An updated search of the same databases was performed from September 2015 to February 2026. Studies were included if (1) they were randomized clinical trial or controlled clinical trial in design, (2) they assessed the efficacy or safety of an intervention for facial aging, (3) they were published in English, and (4) they involved human participants. Complementary sources, including patient interviews, were used to capture further relevant outcomes. Two rounds of Delphi surveys, followed by consensus meetings, were used to identify outcome domains considered most important by both patient and physician stakeholders. Findings The final COS consists of 6 outcome domains: (1) overall convenience of treatment; (2) time to return to normal work and social activity; (3) overall assessment of focused area of treatment (at the point in time when treatment is expected to provide peak benefit); (4) duration of treatment effect; (5) severity of persistent local or systemic adverse events, including pigmentary change, skin texture change, delayed healing, scarring, and serious adverse events; and (6) patient satisfaction with treatment. Conclusions and Relevance The 6 outcome domains identified through a Delphi consensus are recommended for reporting in future facial aging trials to ensure that outcomes that matter most to patients and clinicians are measured and that results are comparable across interventions.

ABSTRACT Objective This study assessed the impact of sex and age on weight loss outcomes in patients receiving tirzepatide in real‐world clinical practice. Methods We conducted a retrospective cohort study of adults with overweight or obesity who initiated tirzepatide at Mayo Clinic between June 2022 and May 2024 and completed ≥ 12 months of continuous therapy. Primary outcome was total body weight loss percentage (TBWL%) at 15 months, stratified by sex and age groups (≤ 45, 46–59, ≥ 60 years). Results Among 1039 patients (57% women; mean age 56 ± 11 years), women achieved significantly greater TBWL% than men after 15 months of treatment (15.1% vs. 10.7%, p < 0.001). Patients aged ≤ 45 years had greater weight loss than those ≥ 60 years (15.1% vs. 12.3%, p = 0.024). In multivariable analyses, greater weight loss was independently associated with female sex, absence of type 2 diabetes, no prior obesity medication use, no concomitant weight gain‐promoting medications, and higher tirzepatide dosage. Age was not an independent predictor. Conclusions Sex, but not age, predicted weight loss with tirzepatide among individuals using the medication continuously for ≥ 12 months. These findings underscore the importance of incorporating sex‐specific considerations into personalized obesity treatment strategies.

Abstract GNE myopathy (GNEM) is a neuromuscular disorder caused by biallelic mutations in the gene GNE , which encodes a bifunctional enzyme essential for the biosynthesis of sialic acid. Despite extensive characterization, no effective therapies or validated biomarkers exist, and the molecular mechanisms driving disease pathology remain poorly understood. This study identifies the proteoglycan serglycin as a preliminary candidate biomarker in GNEM and investigates the mechanisms underlying its dysregulation. Proteomic analysis of serum samples from GNEM patients revealed reduced circulating serglycin levels. In contrast, increased intracellular serglycin was observed in GNE knockout and GNEM patient iPSC-derived myoblasts, suggesting impaired secretion and/or degradation. To investigate the basis of this accumulation, intracellular trafficking and autophagic pathways were examined. Proteomic profiling from HEK GNE knockout cells revealed alterations in pathways involved in membrane trafficking, Golgi function, and glycoprotein processing, consistent with broader disruptions in the secretory system that may impair serglycin export and contribute to its intracellular retention. In GNEM iPSC-derived myoblasts, serglycin overlapped with LAMP1-positive lysosomal compartments and the ER-phagy receptor FAM134B, suggesting association with lysosomal and ER-phagy related pathways. Functional assays further indicated impaired autophagic flux in mutant cells. Together, these findings support a model in which combined defects in secretion and autophagic clearance contribute to intracellular serglycin accumulation and reduced circulating levels. This study identifies serglycin as a potential circulating biomarker for GNEM and highlights dysregulation of secretory and degradative pathways as converging features of disease pathology.

Background. Pancreas transplantation (PT), historically limited to patients with type 1 diabetes (T1D), is currently performed successfully in selected patients with type 2 diabetes (T2D). However, contemporary practice patterns and eligibility criteria for PT in T2D remain incompletely characterized. Methods. The International Pancreas and Islet Transplant Association Pancreas Transplant Interest Group developed an electronic survey to assess center-level approaches to patient phenotyping, candidacy, and peri- and posttransplant management for PT in patients with T2D. The survey was distributed to international transplant professionals during an International Pancreas and Islet Transplant Association Pre-Congress meeting on June 15, 2025. Results. Thirty-seven participants completed the survey. Most respondents’ programs offer PT for T2D only when a kidney transplant is also indicated. Fewer respondents’ programs also offer PT alone (10%), evaluate T2D candidates on a case-by-case basis (3%), or do not offer PT to patients with T2D (10%). Total daily insulin requirement and body mass index (BMI) were the most selected factors in determining eligibility. Considerable variability existed in metabolic thresholds: 62% of programs reported no C-peptide cutoff, whereas nearly half required a BMI of <30 kg/m 2 for C-peptide-positive candidates. Respondents frequently recommend weight-optimization strategies, including lifestyle modification, glucagon-like peptide-1 receptor agonists, and bariatric surgery for candidates exceeding acceptable BMI thresholds. Surgical technique, induction, and maintenance immunosuppression and early posttransplant glycemic management were largely uniform between T2D and T1D recipients. Conclusions. International practice reflects broad but heterogeneous adoption of PT for T2D, with most participants restricting its use to candidates requiring kidney transplantation and emphasizing integrated clinical phenotyping approaches.

BACKGROUND/OBJECTIVES Pediatric hospital medicine (PHM) is a growing field with a unique scholarly perspective and evolving role in academic leadership. Since the last systematic assessment of PHM research in 2009, predating subspecialty certification in 2016 and fellowship accreditation in 2020, the research infrastructure within PHM has not been reevaluated. We sought to assess the current state of PHM research by assessing the number, scope, and scholarly domains of research faculty, as well as research funding and support. METHODS Using the Pediatrics Research in Inpatient Settings Network, we distributed a cross-sectional survey to PHM group leaders across the United States and Canada. The 16-item instrument, adapted from prior PHM and adult hospital medicine surveys, assessed program demographics, faculty effort allocation, research support, funding, and scholarly domains. Surveys were distributed via REDCap with follow-up reminders. Descriptive statistics were used. RESULTS 49 programs responded (51% response rate), representing 1702 faculty (∼40% of US pediatric hospitalists). Fewer than half of programs (n = 21, 43%) reported faculty with more than 50% research effort. One-hundred and ninety faculty members (11%) had dedicated research time, and 72% of those conducting quality improvement research did so without any protected effort. Most PHM programs (n = 27, 55%) received less than $100 000 in total annual research funding. CONCLUSIONS Despite recent PHM subspecialty designation and pediatric hospitalist desire to conduct research, dedicated time and associated supports are uncommon in PHM groups. Improvements in the PHM research pipeline will require understanding institutional financial constraints and diversifying and strengthening research funding.
