Quantifying the Acute Toxicity of Alpha-Synuclein Membrane-Accumulation in a Cell-Based Assay

Abstract Parkinson’s disease (PD) is a progressive neurodegenerative disorder that affects over 12 million people worldwide. A central pathological feature is the accumulation of aggregated alpha-synuclein (αS) in Lewy bodies and Lewy neurites. Engineered αS variants such as 3K (...

Metabolomic profiling reveals distinct and shared biology in COPD and IPF

Chronic Obstructive Pulmonary disease (COPD) and Idiopathic Pulmonary Fibrosis (IPF) are chronic pulmonary disorders with distinct pathologies but shared risk factors. Metabolomics may provide insights into mechanisms. To identify metabolites associated with COPD and IPF, and to...

The effects of royal jelly consumption on glycemia indices, lipid profile, and blood pressure in patients with acute ischemic stroke: a randomized, triple-blind trial

Abstract Aims The effects of royal jelly (RJ) on cardiometabolic risk factors in patients with acute ischemic stroke have not been previously reported from this trial. Therefore, we conducted a secondary analysis to investigate the effects of RJ consumption on glycemic indices, l...

Inflammatory Hot Phases in Arrhythmogenic Cardiomyopathy

Arrhythmogenic cardiomyopathy (ACM) has traditionally been conceptualized as a progressive inherited cardiomyopathy characterized by fibrofatty replacement and ventricular arrhythmias. Emerging clinical and translational evidence suggests that selected patients experience episodi...

Chronic stress disrupts the network among stress granules, P-bodies, and motor proteins

Stress granules (SGs) are dynamic RNA condensates that assemble rapidly in response to cellular stress following translational arrest, thereby promoting adaptation and influencing disease pathogenesis. Although SG assembly and disassembly during acute stress have been extensively...

Responsiveness of epigenetic aging biomarkers to longevity interventions in humans

Abstract Aging biomarkers can potentially allow researchers to rapidly monitor the impact of an aging intervention without the need for decade-spanning trials. However, before the use of aging biomarkers, such as epigenetic clocks, as surrogate endpoints, their responsiveness to...

Differential associations between social determinants of health and the initiation of medications for opioid use disorder across care settings

Abstract Objective This study investigated associations between social determinants of health (SDoH) and time to MOUD initiation across care settings, providing insights for targeted interventions to promote equitable care for OUD patients. Material and Methods We linked patient-...

Early improvement in depressive symptoms after pallidothalamic tract deep brain stimulation for drug-induced dystonia

Stimulation for lithium-induced dystoniaLong-term exposure to psychotropic agents, including lithium and dopamine D2/D3 partial agonists such as brexpiprazole, has been associated with delayed and sometimes persistent

The Impact of Isoniazid Preventive Therapy on Tuberculosis Infection and Disease Progression.

BACKGROUND: Tuberculosis (TB) causes major morbidity and mortality among children worldwide. Isoniazid preventive therapy (IPT) protects against progression to TB disease, but its effect on preventing new TB infection remains uncertain. METHODS: We conducted a longitudinal cohort...

Integrating mental health support into care for placenta accreta spectrum: a qualitative analysis of patient perspectives

Abstract Background Patients with high-risk pregnancies due to placenta accreta spectrum (PAS) are at high risk of morbidity and mortality, which may increase risk for childbirth related mental health sequelae including postpartum post-traumatic stress disorder (PTSD) and trauma...

The hematology workforce in the United States: past, present, and strategies for the future

From 2017-2021, the American Society of Hematology (ASH) completed the largest study ever conducted of the hematology workforce in the United States (US). The study highlighted a deficit in the classical hematology (CH) workforce: despite very high CH clinical volumes encountered...

Paternal Exposure to Endocrine Disrupting Chemicals and Couples’ Pregnancy Outcomes: A Qualitative Review of the Literature

Abstract Purpose of Review Endocrine-disrupting chemicals (EDCs) are ubiquitous, and exposure to them has been associated with adverse reproductive health in both animals and humans. While the adverse effects of maternal EDC exposures on pregnancy outcomes have been extensively i...

Data-driven prediction of fifteen-year all-cause mortality among 2.3 million individuals in the VA

ABSTRACT We present a data-driven framework to predict 15-year all-cause mortality using outpatient administrative records for 2.3 million Veterans in the largest integrated U.S. healthcare system. Rather than relying on predefined clinical phenotypes, we used the 1,000 most comm...

A Panel of Circulating Exosomal sncRNAs Associated With Lung Cancer Risk up to 10 Years in Advance

Current lung cancer screening fails to identify many individuals at risk beyond heavy smokers, highlighting the need for additional predictive biomarkers. This study profiles circulating exosomal small non-coding RNAs (sncRNAs) in a prospective cohort of 202 smokers, including 68...

Focal Therapy for Prostate Cancer

This retrospective study uses data from the National Cancer Database to examine patterns and temporal trends in use of focal therapy for prostate cancer in US cancer centers; characterize inappropriate use in low-, high-, or very–high-risk disease; and describe intermediate-risk...

Psychoactive Medication Prescribing After Critical Illness in American Adults Not Justified by a Documented Supporting Diagnosis

Objectives: To describe psychoactive medication (PM) prescribing in the 30 days after an ICU admission requiring mechanical ventilation not supported by a documented diagnosis in American adults not prescribed a PM before ICU admission. This nondiagnostically supported PM prescri...

Inhibition of RhoA-mediated secretory autophagy in megakaryocytes mitigates myelofibrosis in mice

Abstract Megakaryocytes (MKs) are large, polyploid cells that contribute to bone marrow homeostasis through the secretion of cytokines such as transforming growth factor β1 (TGFβ1). During neoplastic transformation, immature MKs accumulate in the bone marrow where they induce fib...

Cardiovascular Risk Prediction with the Kidney Failure Risk Equation in the Chronic Renal Insufficiency Study

Background: The Kidney Failure Risk Equation (KFRE) is an established tool to predict the risk of kidney failure among patients with CKD. Patients with CKD more often die from cardiovascular (CV) causes than renal causes, and more often experience a non-fatal CV event than progre...

Pitfalls of announcing regulatory policy in medical journals

<b>Sean Tu</b> and <b>Aaron Kesselheim</b> argue that sidestepping established administrative processes to announce major regulatory policies undermines transparency, public participation and trust, and regulatory legitimacy

Rural-Urban Disparities in Contemporary Systemic Therapy for Advanced Prostate Cancer
