Cutting chart-review time and improving database accuracy in inflammatory bowel disease with human-in-the-loop large language models

Abstract Background Manual abstraction of electronic health records into research databases is a major bottleneck in clinical research, limiting scalability and introducing error. This challenge is particularly acute in inflammatory bowel disease surveillance, where clinically re...

Pharmacokinetics of IL-23p19 Inhibitors: A Systematic Review Across Immune-Mediated Inflammatory Diseases

Interleukin (IL)-23p19 inhibitors are increasingly used in immune-mediated inflammatory diseases (IMIDs), particularly inflammatory bowel disease (IBD). Almost half of patients show inadequate response, partly due to pharmacokinetic (PK) variability. However, a comprehensive over...

Immunotherapeutic targeting of calreticulin mutant myeloproliferative neoplasms

Abstract Calreticulin (CALR) frameshift mutations drive the majority of JAK2 / MPL -wild-type cases of essential thrombocythemia and myelofibrosis, producing a shared novel C-terminus that activates the thrombopoietin receptor and leads to constitutive Janus kinase (JAK)/signal t...

Virtual coronary artery bypass grafting

<title>Abstract</title> Coronary artery bypass grafting (CABG) offers superior long-term survival over percutaneous coronary intervention (PCI) or medical therapy in patients with complex coronary artery disease (CAD). This prospective proof-of-concept study aims to develop and v...

Moving From Laboratory to Clinical Metrics for Diagnostic Tests

This Viewpoint explores the distinction between analytical and diagnostic performance measures.

Laser Interstitial Thermal Therapy for Brain Tumors: A Prospective Multicenter Analysis of Patients From the LAANTERN Study

Background: Laser interstitial thermal therapy is a surgical tool used to ablate brain tumors, radiation necrosis, and epileptic foci. Data from the completed LAANTERN prospective multicenter registry (NCT02392078), containing tumor patients enrolled in the study across 25 US cen...

Study protocol for first national vasa previa perinatal registry

Vasa previa is a rare but potentially catastrophic obstetric condition characterized by unprotected fetal blood vessels over or adjacent to the internal cervical os. Although advances in prenatal ultrasound have dramatically improved neonatal survival through planned cesarean del...

Acute effects of the 1-minute sit-to-stand test (STST) on immune-metabolic stress indices

Abstract Characterizing the non-pathological, exercise-induced immune-metabolic stress regulation is important for understanding physiological adaptations and distinguishing them from maladaptive responses. Because such responses are mostly studied with extensive, resource-intens...

Community-Led Operationalization of a Champion Implementation Strategy for Anal Cancer Prevention in Nigeria

Abstract Context-specific adaptation of implementation strategies is an important component of promoting evidence-based intervention use. But guidance on systematic approaches is limited. Here we described our mixed method approach to adapting (Study 1) and monitoring (Study 2) a...

Technical note: reconstructing dose distributions from manually planned electron boosts in breast radiotherapy

Purpose In breast radiotherapy, delivery of manually-calculated electron boosts limits retrospective dose–response analyses as dose distribution is unavailable. This work evaluates the feasibility of reconstructing dose distributions from manually planned electron boosts in breas...

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...

Nuclear activities and interactome of the NS5 protein of tick-borne encephalitis virus

Orthoflaviviruses are RNA viruses responsible for significant diseases in humans, domesticated animals, and wildlife. Their NS5 protein is central in viral replication, functioning both as an RNA-dependent RNA polymerase and a methyltransferase, while also modulating cellular pro...

Sociodemographic bias in LLMs’ clinical decision-making for dizziness

Objective As large language models (LLMs) enter clinical decision support, concerns persist about sociodemographic bias. We assessed whether LLM recommendations for dizziness vary by patient descriptors and clinical detail. Methods We conducted a cross-randomized in-silico vignet...

Peripheral Nerve Entrapment Mimics of Overuse Syndromes

Repetitive use injuries are commonly seen by musculoskeletal providers, usually in the form of tendinopathies. However, focal peripheral nerve entrapment can mimic or coexist with tendon pathology, particularly when weakness, sensory symptoms, or imaging findings are subtle or no...

A Vagal–Renal–Splenic Reflex Suppresses Renal Sympathetic Nerve Activity and Preserves Kidney Function After Ischemic Injury

Background: Acute kidney injury (AKI) is associated with maladaptive increases in renal sympathetic nerve activity (RSNA) and frequently progresses to chronic kidney disease. Neuromodulatory strategies that suppress sympathetic outflow may provide therapeutic benefit. We tested w...

Effect of Abrocitinib on the Skin Microbiome in Patients With Moderate‐to‐Severe Atopic Dermatitis

BACKGROUND: Atopic dermatitis (AD) is characterized by microbial dysbiosis, notably an overabundance of Staphylococcus species. This study aimed to evaluate the effects of abrocitinib, a Janus kinase 1-selective inhibitor, on the skin microbiome and clinical outcomes in patients...

Effects of early adulthood chronic sleep disruption on late life cognition, brain pathology, and microglial reactivity in the PS19 mouse model of tauopathy

Abstract A bidirectional relationship has been proposed between sleep and Alzheimer’s disease pathology, such that disruption to sleep can lead to increases in the expression of tau or its phosphorylation. Over the long term, this can potentially lead to greater expression of neu...

Timing of Food Introduction and Allergy Prevention: An Update.

Recommendations about allergy prevention through diet are rapidly changing. In just the past several years, multiple organizations have provided updated guidance and recommendations about infant feeding based on recent studies and meta-analyses. In addition to the increased numbe...

Primary Cilia Regulate the Mechanical Adaptation of the Tendon and Enthesis via Hedgehog Signaling

Background: Physical loading mediates postnatal growth, homeostasis, and healing of the tendon and its attachment to bone, which is critical for rotator cuff functional integrity. Our prior studies have highlighted the mechano-sensing role of primary cilia; However, the mechanism...

Context-sensitivity and longitudinal stability of the effects of depressive symptoms on social and reward decision-making

Depressive symptoms could affect decision-making in multiple ways, yet it remains unclear whether these effects are context-sensitive or stable over time. In this longitudinal study, 236 online participants (n=129 at 1-month follow-up) completed a social exchange task (Ultimatum...
