Mediating effect of pro-inflammatory cytokines in the association between depression, anxiety, and cardiometabolic disorders in a multiethnic US population

Abstract Neuroinflammation is associated with depression and anxiety risk, both of which demonstrate a bilateral relationship with cardiometabolic disorders. Systemic inflammation was also commonly described in patients with cardiometabolic disorders. It is, thus, unclear whether...

Desulfinylation of the deubiquitinase USP7 by SRXN1 attenuates oxidative acute liver injury

Protein S -sulfinylation is a reversible oxidative cysteine modification, but its contribution to acute liver injury such as those induced by acetaminophen (APAP) overdose has not been reported. Sulfiredoxin-1 (SRXN1) is the only oxidoreductase known to reduce the sulfinylated pr...

Complete genome sequences of bacteriophages Crescenzo, Roberts, and Gerri43 isolated from Arthrobacter globiformis

ABSTRACT We report the complete genome sequences of the Arthrobacter globiformis B-2979 phages Crescenzo, Roberts, and Gerri43. Crescenzo contains unique genes without recognizable homologs, while Roberts and Gerri43 lack a ribonucleotide reductase gene. Roberts genes 52 and 61 l...

On the Inhibition of Lipid Peroxidation and Ferroptosis by Fatty Acids

Most inhibitors of lipid peroxidation (LPO) and associated ferroptosis are small molecules that trap LPO-propagating radicals. Among the handful of other inhibitors are select fatty acids: monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids substituted with deuter...

The Effect of Ethnic Stereotypes and Evaluators’ Ethnic Identity on Funding-Worthiness: Evidence About Latinx Entrepreneurs in the United States

Abstract Despite the growing importance of entrepreneurship as a pathway to economic mobility, ethnic minority entrepreneurs continue to face persistent disadvantages in access to capital, particularly following business failure. This study examines how ethnic stereotypes and eva...

Clinical Practice Guideline for the Diagnosis and Treatment of Urinary Tract Infection in Children From 8 Days to 5 Years of Age

Urinary tract infection (UTI) is one of the most common bacterial infections in infants and young children, with a prevalence of 7% in infants with fever. This clinical practice guideline (CPG) provides an update of the literature and clinical recommendations of the 2011 American...

Urinary Tract Infection Diagnosis—A Companion to the American Academy of Pediatrics’ 2026 Clinical Practice Guideline on the Diagnosis and Management of Urinary Tract Infection: Technical Report

Accurate diagnosis is essential to appropriate care. Although urinary tract infection (UTI) is one of the most common bacterial infections in children, there is no gold standard for its diagnosis. During the American Academy of Pediatrics' revision of its Clinical Practice Guidel...

A Systematic Review and Meta-Analysis of the Role of Ultrasonography for the Diagnosis of Vesicoureteral Reflux in Pediatric Patients Following Urinary Tract Infections: Technical Report

BACKGROUND: Vesicoureteral reflux (VUR) may be present in as many as 40% of children without known underlying neurogenic bladder or anatomic abnormalities in whom a first urinary tract infection (UTI) is diagnosed. This article reports on a technical review investigating the diag...

Evolutionary regimes determine the accuracy of epistasis inference from temporal genetic data

Epistasis, the non-additive effects of mutations, shapes fitness landscapes and evolutionary trajectories. Temporal genetic data reveal evolutionary dynamics and could be used to infer epistatic interactions, especially through linkage disequilibrium (LD) between interacting muta...

Assessing residual bias in real-world vaccine effectiveness studies: validating negative controls to avoid misleading results

Observational studies and randomized controlled trials demonstrate that vaccines protect against infections and severe outcomes, but real-world vaccine effectiveness estimates remain vulnerable to residual biases. Negative control outcomes can help detect and mitigate such biases...

Early insights into predicted efficacy of Ebola monoclonal antibodies for the 2026 Bundibugyo virus disease outbreak

The 2026 Bundibugyo virus disease (BVD) outbreak in the DRC and Uganda raises urgent questions about the efficacy of existing Ebola virus (EBOV) monoclonal antibodies (mAbs) against Bundibugyo virus (BDBV). Here, we perform genomic and structural analyses of 44 BDBV sequences, in...

Top Ten Tips Palliative Care Clinicians Should Know About Collaborating with Consultation-Liaison Psychiatry

Palliative care (PC) and consultation-liaison (CL) psychiatry are complementary clinical disciplines that frequently care for the same patients facing serious illness complicated by psychiatric symptoms, psychological distress, neuropsychiatric syndromes, and high-stakes medical...

Cardiovascular risk factors at 24-months after risk reducing oophorectomy- a prospective controlled study from WHAM

Structured Abstract Background Women at risk of ovarian cancer due to BRCA1/2 pathogenic variants are advised to undergo bilateral risk-reducing salpingo-oophorectomy (RRSO) prior to natural menopause. Epidemiologic evidence suggests that surgical menopause increases cardiovascul...

Clinical Improvement, No Improvement, and Worsening at 24 Hours Following Reperfusion in Patients With Stroke due to Large-Vessel Occlusion

BACKGROUND: Restoring blood flow to ischemic tissue is the cornerstone of acute stroke therapy and is usually beneficial. However, when reperfusion is achieved for severely injured tissue, it is often futile and may occasionally cause harm. We aim to determine the prevalence and...

Spirituality Moderates The Relationship of Stress-Linked Psychosocial Factors To Cortisol Homeostasis and Allostatic Load Among Afro-Caribbean Women

AIM: It is hypothesized that a chronic defeat response to social or environmental stressors increases the likelihood of dysfunction of the hypothalamic-pituitary-adrenal (HPA) axis with dysregulation of cortisol, accumulation of abdominal fat and development of glucose intoleranc...

Single-nucleus transcriptome-wide association study of human brain disorders

Abstract Common brain disorders impose a substantial health burden, but localizing their genetic risk in the brain remains challenging 1 . Although genome-wide association studies have identified numerous loci associated with neuropsychiatric and neurodegenerative disorders, many...

Personalized single-cell transcriptomics reveals molecular diversity in Alzheimer’s disease

Alzheimer’s disease (AD) is highly heterogeneous and driven by diverse molecular and cellular mechanisms. Functional genomics investigates these mechanisms from genetic variants to gene expression and regulation. We performed personalized functional genomics analysis on populatio...

Single-cell atlas of transcriptomic vulnerability across brain disorders

Abstract Neurodegenerative and neuropsychiatric diseases impose a considerable societal and public health burden. However, our understanding of the molecular mechanisms underlying these highly complex conditions remains limited 1,2 . Here, to gain deeper insights into the aetiolo...

Lifespan single-cell transcriptomic atlas of the human prefrontal cortex

The human brain undergoes profound changes from early development through late adulthood, shaping cognition, behaviour and vulnerability to disease1,2. Understanding how these changes are organized within specific brain regions and cell types is essential for interpreting normal...

Single-nucleus atlas of cell-type specific genetic regulation in the human brain

Abstract Genetic risk variants for common diseases are predominantly located in non-coding regulatory regions and modulate gene expression. Although bulk tissue studies have elucidated shared mechanisms of regulatory and disease-associated genetics, the cellular specificity of th...
