Article Abstract
The Nanopig™ model is an emerging non-rodent platform for (bio)pharmaceutical safety assessment, with potential advantages for translational research. Here, we report initial characterization results using whole genome sequencing (WGS) and tissue-based proteomics, focusing on drug metabolism and immune system relevance. WGS produced a high-quality Nanopig™ genome assembly (2.8-2.9 Gb), with >98 % alignment to the Duroc pig reference genome, and identified key metabolic and immune-related genes, including 47 cytochrome P450 (CYP450) genes with high homology to human CYP450 families. Proteomic profiling of 15 pharmaceutically relevant tissues revealed human orthologous drug metabolism enzymes and transporters (DMETs), as well as immune-related proteins, indicating similarities to human CYP450 enzyme abundance and tissue distribution. Functional evaluation of hepatic CYP450 activity yielded kinetic parameters (K, V) in the range observed in humans and beagle dogs. These early findings represent a foundational multi-omics dataset for the Nanopig™, suggesting its future use as a translational model in preclinical safety assessment. This work provides an early framework for species selection strategies and model optimization, with the long-term goal of reducing reliance on traditional non-rodent species in drug development.

Randomized trial of activated vitamin D for acute kidney injury prevention in critically ill patients.
JCI Insight
September 2025
Division of Nephrology, Boston University Chobanian & Avedisian School of Medicine, Boston, United States of America.
Background: Active vitamin D metabolites, including 25-hydroxyvitamin D (25D) and 1,25-dihydroxyvitamin D (1,25D), have potent immunomodulatory effects that attenuate acute kidney injury (AKI) in animal models.
Methods: We conducted a phase 2, randomized, double-blind, multiple-dose, 3-arm clinical trial comparing oral calcifediol (25D), calcitriol (1,25D), and placebo among 150 critically ill adult patients at high-risk of moderate-to-severe AKI. The primary endpoint was a hierarchical composite of death, kidney replacement therapy (KRT), and kidney injury (baseline-adjusted mean change in serum creatinine), each assessed within 7 days following enrollment using a rank-based procedure.
Interventions to bolster benefits take-up: Assessing intensity, framing, and targeting of government outreach.
Proc Natl Acad Sci U S A

Behaviorally informed "nudges" are widely used in government outreach but are often seen as too modest to address poverty at scale. In four field experiments over 2 y ( = 542,804 low-income households), we test whether more proactive communication, varying message framing, and more precise targeting can boost take-up of tax-based benefits in California above and beyond traditional light-touch approaches. Our interventions focused on extremely vulnerable households, most with no prior-year earnings, who were at risk of missing out on two crucial benefits: the 2021 expanded Child Tax Credit and pandemic-relief Economic Impact Payments.

JAMA Netw Open
September 2025
Department of Psychiatry, Psychosomatics, and Psychotherapy, University of Lübeck, Lübeck, Germany.
Importance: Patients with inflammatory rheumatic diseases (IRDs) frequently experience psychological distress; however, access to psychological support remains limited.
Objective: To investigate the effectiveness of a digital psychological intervention for individuals with IRDs.
Design, Setting, And Participants: Participants aged 18 years or older were recruited across Germany between February 22 and June 4, 2024, if they had been diagnosed with rheumatoid arthritis, psoriatic arthritis, or systemic lupus erythematosus and reported psychological distress and reduced quality of life.
Left Atrial Appendage Occlusion vs Anticoagulants in Dialysis With Atrial Fibrillation.
JAMA Netw Open
September 2025
Department of Internal Medicine, University of Arkansas for Medical Sciences, Little Rock.
Importance: Patients with kidney failure (KF) receiving long-term dialysis have increased incidence of atrial fibrillation (AF). Patients with KF and AF have increased risk of stroke, death, and bleeding compared with age-matched cohorts. In KF, the use of oral anticoagulants (OACs) increases hemorrhage risk, offsetting potential benefits and making left atrial appendage occlusion (LAAO) a potentially promising solution for risk reduction in AF.

Department of Medicine, Division of Cardiovascular Disease, University of Alabama at Birmingham, 521 19th Street South-GSB 444, Birmingham, AL, 35233, USA.
Purpose Of Review: This review examines cardiovascular disease (CVD) risk prediction models relevant to older adults, a rapidly expanding population with elevated CVD risk. It discusses model characteristics, performance metrics, and clinical implications.
Recent Findings: Some models have been developed specifically for older adults, while several others consider a broader age range, including some older individuals.
