Preoperative Visual Field Patterns Associated with Selection for Concurrent Eyelid and Brow Ptosis Repair

Introduction: Determining when to perform combined eyelid and brow surgery for functional deficits remains subjective, despite measurable visual field (VF) impairment in affected patients. Objectives: We sought to identify VF patterns associated with selection for combined eyelid...

Implementing liquid biopsy in HR+/HER2− metastatic breast cancer: challenges and opportunities

PURPOSE OF REVIEW: Liquid biopsy (LB) is rapidly transforming the management of hormone receptor-positive/HER2-negative (HR+/HER2-) metastatic breast cancer (mBC). In this review, we discuss the most recent findings on circulating tumor DNA (ctDNA) and circulating tumor cells (CT...

Threatened Identity: Self Psychology Informed Communication for Serious Illness Care

Serious illness threatens both the body and the self: the coherent, continuous sense of who one is, from bodily integrity to psychosocial identity. When illness disrupts identity and patients confront mortality and dependence, a range of responses may follow, including behaviors...

A qualitative evaluation of clinicians’ experiences in diagnosis and management of women with gestational diabetes mellitus (GDM) in Pune, India

The prevalence of gestational diabetes mellitus (GDM) continues to rise in India, and globally. However, uncertainty remains regarding its diagnosis and optimal management. We explored how clinicians in India navigate GDM-related care to identify where additional guidelines or tr...

The Global Epidemiology of Metabolic Dysfunction-Associated Steatotic Liver Disease: Regional Hotspots, Trends, and Future Projections

Purpose of Review This review highlights the global prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD), assesses comparability of the former definition of non-alcoholic fatty liver disease (NAFLD)-era estimates with the 2023 steatotic liver disease (SL...

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...

Towards a multi-agent Clinical Trial Center framework to support modern clinical trials

Abstract Clinical Trial Centers (CTCs) manage complex multi-site trials under rising regulatory and operational demands. Traditional workflows are labor-intensive and error-prone. Existing AI handles narrow and siloed tasks. We introduce Agent System for TRial Automation (ASTRA),...

Navigating physician-scientist careers: insights from American Board of Internal Medicine Research Pathway graduates

The American Board of Internal Medicine Research Pathway (ABIM RP) is designed to train physician-scientists by shortening postgraduate clinical training and increasing research time. We surveyed ABIM RP graduates to understand career trajectories, research engagement, and barrie...

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...

Hypoxia-activated scleraxis a mediates epicardial progenitor differentiation into a unique cardiac perivascular cell type

Abstract The epicardium is a crucial source of progenitor cells and paracrine signals that support heart development and regeneration. However, the molecular mechanisms that guide epicardial cell fate decisions remain incompletely understood. Here, we identify the transcription f...

Commensal bacteria inhibit viral infections via a tryptophan metabolite

Clinical outcomes following viral exposures exhibit substantial interindividual variability. Although developing evidence suggests commensal bacteria modulate viral infections, the specific bacteria and mechanisms remain underexplored. Here, we define a pathway by which viral inf...

Wnt Pathway Agonism as a Therapeutic Strategy for Retinal Vascular Diseases: A Narrative Review of Evidence to Date

Breakdown of the blood–retinal barrier (BRB) is implicated in many blinding retinal diseases, including diabetic macular edema, neovascular age-related macular degeneration, and retinal vein occlusion. Anti-vascular endothelial growth factor (anti-VEGF) therapies or laser photoco...

Gut microbiota and complications in kidney transplantation: a balancing act between commensal and pathogenic bacteria

PURPOSE OF REVIEW: Recent work has linked gut dysbiosis, an imbalance of commensal and pathogenic bacteria, to complications in kidney transplant recipients. The purpose of this review is to evaluate the gut microbiota's relationship to important complications in kidney transplan...

Outcomes of Moderate-to-Severe Traumatic Brain Injury in a Low-Resource Setting

Importance: No study from a low- and middle-income country (LMIC) has reported long-term mortality and quality of life (QOL) after moderate to severe traumatic brain injury (msTBI), highlighting its burden and recovery trajectories. Objectives: To measure short- and long-term mor...

CAR T cell therapy beyond cancer: current status, challenges and future prospects

Chimeric antigen receptor (CAR) T-cell therapy has revolutionized oncology, and its foundational logic-precise antigen recognition coupled with durable effector activity-extends naturally to chronic non-malignant diseases sustained by long-lived pathological cells. These include...

Targeting Oncogenic KRAS Using Peptide Nucleic Acid Oligomers Attached to Cell-Penetrating Peptides

Approximately 30% of tumors contain an activating mutation in the oncogene KRAS, leading to increased cell proliferation that often promotes non-small cell lung cancers, colorectal adenocarcinomas, pancreatic ductal adenocarcinomas (PDAC), and other cancers. Among the most common...

Macrophages tune NK cell IFNγ production through direct lipid transfer

Abstract Natural killer (NK) cells are critical effectors of innate immunity, but their activity is strongly influenced by metabolic state. While intrinsic NK metabolism has been studied extensively, less is known about how surrounding immune cells shape NK cell function. Here, w...

Lipidomic and transcriptomic remodeling underlies early retinal pathogenesis in dry age-related macular degeneration

Abstract Dry age-related macular degeneration (AMD) is initiated by retinal pigment epithelium (RPE) dysfunction, yet early metabolic mechanisms linking RPE injury to photoreceptor dysfunction remain unclear. Using a physiologically relevant mouse model, we performed cell-type–re...

A compendium of next-generation patient-derived models for diverse cancers

Abstract The development of new therapeutics and the validation of pathogenetic cancer mechanisms require representative laboratory models 1,2 . However, existing collections represent only a fraction of the diversity observed in human cancer 2–4 . Recent technologies have enable...

Is Postinflammatory Hyperpigmentation Truly “Post” in People With Darker Skin Tones?

This Viewpoint reviews how inflammation can coexist with hyperpigmentation, explains why inflammatory activity may be underrecognized in people with darker skin tones, and proposes an approach in which hyperpigmentation prompts continued assessment for persistent inflammation.
