Autophagic degradation of RAB8A promotes ferroptosis through dysregulation of TFRC-mediated iron uptake

Ferroptosis is an iron-dependent form of regulated cell death driven by lipid peroxidation; however, how selective autophagy regulates ferroptotic sensitivity remains incompletely understood. Here, we identify RAB8A as a selective autophagic substrate and negative regulator of fe...

Effect of Aficamten on Cardiac Structure and Function in Patients with Symptomatic Nonobstructive Hypertrophic Cardiomyopathy

BACKGROUND: Aficamten significantly improved both functional capacity and patient-reported health status in patients with symptomatic nonobstructive hypertrophic cardiomyopathy in the phase 3 randomized, placebo-controlled ACACIA-HCM trial (Assessment Comparing Aficamten to Place...

Aspartate-dependent polyamine biosynthesis in bacteria: chemical synthesis of carboxypolyamines and mechanism-based design of hydroxylamine-containing inhibitors of carboxyspermidine decarboxylase

Abstract Biogenic polyamines spermidine, spermine and some of their derivatives are small organic polycations vitally important in all domains of life. Recent studies have demonstrated that polyamine biosynthesis is subject to convergent evolution and that some bacteria employ bi...

B Cell Mechanisms Underlie IgG Glycan Alterations in Obesity

Abstract Insulin resistance is a major complication of obesity. In adults with obesity insulin resistance is associated with a hyposialylation of the Fc-linked glycan on IgG, and a causal link between IgG hyposialylation and glucose dysregulation has been demonstrated in obese mi...

Aficamten for Symptomatic Nonobstructive Hypertrophic Cardiomyopathy

BACKGROUND: Nonobstructive hypertrophic cardiomyopathy (HCM) is a common condition that is associated with substantial morbidity and no proven medical therapy. Whether treatment with aficamten, a cardiac myosin inhibitor, can benefit patients with this condition is unknown. METHO...

A Multilevel Intervention to Identify Individuals for Genetic Testing and Treatment

Importance Cascade genetic testing (CGT) is a key strategy for cancer prevention in families with hereditary breast and ovarian cancer syndrome (HBOC) and Lynch syndrome (LS), yet uptake among at-risk relatives remains persistently low, particularly in medically underserved popul...

Impact of Response to Hypomethylating Agent‐Based Therapy on Survival Outcomes in the Context of Baseline Clinical‐Molecular Risk and Transplant Status in Patients With Higher‐Risk Myelodysplastic Syndromes/Neoplasms: An analysis From the International Consortium for MDS (icMDS)

Baseline IPSS-M risk, response to hypomethylating agent (HMA) therapy, and receipt of allogeneic stem cell transplant (allo-HCT) have all been individually shown to impact overall survival (OS) in patients with myelodysplastic syndromes (MDS). However, the prognostic impact of re...

Impact of prompt engineering and workflow modifications on the performance of a Delphi-based automated abstract screening system in a psychiatric systematic review

Large language models (LLMs) can facilitate the labor-intensive screening of literature for systematic reviews and meta-analyses. Ensembling multiple LLMs to reach consensus on screening may allow locally deployed LLMs to achieve acceptable performance while reducing hallucinatio...

Auditory–Somatosensory Influences on Vocal Motor Control in Primary Muscle Tension Dysphonia

PURPOSE: Auditory and somatosensory systems jointly support vocal motor control, yet their relative contributions in primary muscle tension dysphonia (pMTD) remain poorly understood. This study examined how auditory and somatosensory feedback influence vocal motor control and ada...

Uveitis-Associated Ocular Hypotony: A Systematic Review

INTRODUCTION: Chronic hypotony is an uncommon but potentially vision-threatening complication of uveitis, particularly in pediatric populations. This review synthesizes current evidence on its pathophysiology, epidemiology, clinical presentation, diagnosis, management, and progno...

A community-validated tool for clinical outcome calculation in multiple sclerosis: Consensus development and scenario-specific recommendations

Background: Reproducibility and comparability of disability outcomes remain major challenges in multiple sclerosis (MS) research. Definitions of disability progression vary widely across studies, and calculation criteria are often insufficiently documented to enable replication....

Circulating lipids are associated with PTSD severity and predict symptomatic PTSD in a cohort of veterans and service members

Abstract Post-traumatic stress disorder (PTSD) is characterized by chronic stress, alterations in mood, and avoidance after a traumatic event has occurred. While recovery can occur, many PTSD patients suffer life-long impairments. In combat veterans, high rates of PTSD contribute...

Cuproptosis: an emerging member of the immunogenic cell death family

Cell death was long considered the terminal consequence of cellular stress or damage, and distinct cell death modalities were classified according to their molecular execution mechanisms rather than their immunological impact [ 1 , 2 ]. This reductionist view has progressively be...

Danburstotug, an anti‐ PD ‐ L1 antibody, in relapsed/refractory extra‐nodal natural killer/T‐cell lymphoma: The phase 2 DISTINKT study

Summary Relapsed/refractory extra‐nodal natural killer/T‐cell lymphoma (R/R ENKTL) has limited treatment options. Danburstotug, an antibody targeting programmed death‐ligand 1 (PD‐L1), was evaluated in adults with R/R ENKTL in a phase 2, open‐label study (NCT04414163). Danburstot...

Combined Post- and Precapillary Pulmonary Hypertension in Patients With Advanced Heart Failure

Pulmonary hypertension associated with left heart disease, or group 2 pulmonary hypertension, is common in patients with advanced heart failure. In at least a third of these patients, the pulmonary pressures are disproportionately elevated relative to left heart filling pressures...

Long-Term Fatigue After Treatment for Breast Cancer

Importance Patients with breast cancer (BC) may have long-term fatigue after treatment, which is associated with reduced quality of life. Objective To identify cardiac, psychological, and cancer treatment factors associated with fatigue before and 24 months after BC treatment. De...

Smart Lithotripsy: Lasers, Energy Sources and Efficiency

PURPOSE OF REVIEW: To examine the evidence on contemporary lasers and provide a practical framework for platform selection, parameter optimization, and thermal safety based on the principles of smart lithotripsy. RECENT FINDINGS: Holmium: yttrium-aluminum-garnet (Ho:YAG) remains...

Identifying phenotype-genotype-function coupling in 3D organoid imaging using Shape, Appearance and Motion Phenotype Observation Tool (SPOT)

Abstract Live cells in tissue are plastic, phenotypically dynamic, and modify their function in response to genetic and environmental perturbations. To unleash the power of live-cell imaging to identify phenotype-genotype-function coupling over time, we report the development of...

The Influence of Religion, Country of Origin, and United States Acculturation on Stress Coping Techniques in a Spanish-Speaking Free Clinic Population

Introduction Many Spanish-speaking individuals in the United States experience high levels of stress but disproportionately underutilize mental health services due to cultural, socioeconomic, and religious barriers in accessing culturally relevant mental health care. Methods Cros...
