Functional fractionation of large-scale brain networks in the human subcortex

Brain network mapping plays a crucial role in advancing our understanding of human brain organization and the neuroanatomic foundations of cognition. Historically, the identification of large-scale brain networks has focused on the cerebral cortex. Some cortical networks have bee...

Visual motion does not bias gravity-referenced vestibular coding in the primate cerebellar nodulus and uvula

Visual motion is known to influence perceptions of tilt, verticality, and translation, suggesting that optic flow is combined with vestibular cues to estimate orientation relative to gravity. The cerebellar nodulus and ventral uvula (NU) are a prime candidate to perform this comp...

Dietary protein governs the role of insulin signaling in the postprandial regulation of hepatic mTORC1

The nutrient-sensing mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway controls cellular and organismal growth and metabolism, while aberrant activation is linked to human disease, including metabolic disease. Cellular studies have established several regulator...

Military Service and Survival Among Persons With ALS in the U.S. National ALS Registry, 2011–2023

ABSTRACT Introduction/Aims Military service has been associated with increased risk of amyotrophic lateral sclerosis (ALS) but less is known about survival after diagnosis. We evaluated the association between military service and survival after ALS diagnosis among U.S. National...

Digital Outreach to Improve Statin Refills in Patients With Low Statin Adherence

Importance Statin nonadherence is a leading, addressable driver of preventable cardiovascular events. Although health systems routinely use outreach to promote preventive care, most strategies are static and lack evidence from randomized clinical trials. Objective To determine wh...

Continued high mortality following diagnosis of HIV-associated Kaposi sarcoma in East Africa in the “Treat All” antiretroviral therapy era ― 2021-2024

Abstract Background Stage at time of diagnosis and survival after diagnosis are critical parameters regarding control of any cancer in any geographical setting. In earlier research focusing on the initial years of the “Treat All” era (2016-2019), we found that HIV-associated Kapo...

Bivalent RSV Prefusion F Vaccine to Prevent Hospitalizations in Adults

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of severe respiratory disease in adults, with the highest burden among older adults and individuals with chronic health conditions. The bivalent RSV prefusion F (RSVpreF) vaccine has been shown to prevent RSV-ass...

Milvexian with Antiplatelet Therapy after Acute Coronary Syndrome Event

BackgroundPatients are at increased risk for recurrent ischemic events after an acute coronary syndrome event. Milvexian, an oral factor XIa inhibitor, may reduce the risk of major adverse clinical events with minimal bleeding risk. MethodsIn this phase 3, randomized, placebo-con...

Mapping Essential Genes in Klebsiella pneumoniae Using Transposon-Insertion Sequencing (Tn-seq)

Abstract Background Klebsiella pneumoniae is a common cause of sepsis in adults and children. Given the emergence of multidrug-resistant isolates, there is an urgent need to develop novel therapeutic strategies. Essential bacterial genes and their products, which are critical to...

Incidence, risk factors, and prognostic implications of hospitalizations for heart failure among patients with myeloproliferative neoplasms

Myeloproliferative neoplasms (MPNs), including essential thrombocythemia (ET), polycythemia vera (PV), and myelofibrosis (MF), are a group of chronic leukemias associated with increased risk of heart failure (HF). Despite a link between MPNs and HF, prognostic implications and ri...

Durability of RSV Prefusion F Vaccine Protection across Two RSV Seasons

BACKGROUND: Respiratory syncytial virus (RSV) is an important cause of hospitalization and death among older adults. Although first-season vaccine effectiveness against RSV-related hospitalization has been demonstrated for the bivalent RSV prefusion F protein-based vaccine (RSVpr...

Nanobodies specific for Vβ11 enable detection and noninvasive imaging of antigen-specific T cells in vivo

Through screening of a VHH phage display library constructed from an alpaca immunized with the recombinantly expressed murine myelin oligodendrocyte (MOG)-specific 2D2 T cell receptor (TCR), we identified nanobodies that reduced antigen-driven 2D2 T cell activation in vitro. Immu...

PrEP reinitiation, uptake, and persistence as targets for reducing HIV incidence and racial and ethnic inequities among men who have sex with men in Boston, USA: a network modeling study

Background A decade of pre-exposure prophylaxis (PrEP) has lowered HIV incidence among men who have sex with men (MSM) but not enough to meet Ending the HIV Epidemic goals, and racial and ethnic disparities persist. The PrEP era has produced a population of former users facing lo...

Exploring the mediating role of working alliance in a peer support intervention for late-life depression

Objective: Peer support is an evidence-based intervention for depression, yet the mechanisms underlying its effectiveness remain understudied, particularly in randomized clinical trials. This study examined the mediating role of working alliance components (task, bond, and goal)...

Associations of nova-defined ultra-processed food intake and cardiometabolic health among Korean adults from 2007 to 2023

The consumption of ultra-processed foods (UPFs) has been increased worldwide. Given its association with adverse health outcomes, monitoring long-term trends in UPF intake is important. However, evidence among Asian adults on UPF intake and health outcomes is limited. We analyzed...

Variation in meningioma recurrence risk estimates across observational cohorts: the influence of calendar time, WHO classifications, geographical settings, and healthcare systems

Abstract Purpose Recurrence risk estimates underpin meningioma research, including molecular classification and clinical trial benchmarking, yet are often based on retrospective or historical data. The aim of this study was to assess the variation of recurrence risk estimates acr...

Edge universality of random regular graphs of growing degrees

We consider the statistics of extreme eigenvalues of random d-regular graphs, with Nc≤d≤N1/3−c for arbitrarily small c>0. We prove that in this regime, the fluctuations of extreme eigenvalues are given by the Tracy–Widom distribution. As a consequence, about 69% of d-regular grap...

Use of Electroconvulsive Therapy for Catatonia in Down Syndrome Regression Disorder: A Systematic Review, Case Series, and Analysis

Abstract Purpose Down syndrome regression disorder (DSRD) is a condition occurring in young people with Down syndrome. It is associated with functional decline, new onset psychopathology, and increased support needs. DSRD is often associated with catatonia, for which electroconvu...

Ultra-processed food intake, genetic polymorphisms, and the risk of obesity in a pooled analysis of three prospective cohorts

Obesity is a major risk factor for non-communicable diseases and mortality. This study aimed to examine the associations between ultra-processed food intake and the risks of obesity and weight gain, and to evaluate whether these associations differed by polygenic scores for obesi...

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...
