Warfarin is a widely used vitamin K antagonist (VKA) with known pleiotropic effects beyond anticoagulation. Preclinical and case-control evidence suggests that warfarin may affect hematopoiesis, but longitudinal human evidence is lacking. To explore this potential effect, we conducted a post-hoc analysis of participants in the Hokusai-VTE and ENGAGE AF-TIMI 48 trials, which randomized patients to warfarin or the direct oral anticoagulant edoxaban with routine laboratory testing at predefined follow-up visits.

Background: Oral emtricitabine/tenofovir disoproxil fumarate (F/TDF) preexposure prophylaxis (PrEP) effectiveness against HIV acquisition highly depends on adherence. For men who have sex with men, a dosing study in the United States (US) population defined clinically meaningful tenofovir diphosphate (TFV-DP) thresholds in dried blood spots (DBS) based on the rounded 25th percentile for 2, 4, and 7 doses/week as 350, 700, and 1,250 fmol/punch. However, divergent efficacy results in the first generation randomized clinical trials of F/TDF PrEP among African women led to several hypotheses to question whether the pharmacology and adherence requirement for oral F/TDF PrEP may be different in cisgender women compared to what is already established for men.

Background: Current aftercare in breast cancer survivors aims to detect local recurrences or contralateral disease, while the detection of distant metastases has not been a central focus due to a lack of evidence supporting an effect on overall survival. However, the data underpinning these guidelines are mainly from trials of the 1980s/1990s and have not been updated to reflect the significant advancements in diagnostic and therapeutic options that have emerged over the past 40 years. In this trial, the aim is to test whether a liquid biopsy-based detection of (oligo-) metastatic disease at an early pre-symptomatic stage followed by timely treatment can impact overall survival compared to current standard aftercare.

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.

Purpose: Glioblastoma (GBM) remains one of the most aggressive primary brain tumors with poor survival outcomes and a lack of approved therapies. A promising novel approach for GBM is the application of photodynamic therapy (PDT), a localized, light-activated treatment using tumor-selective photosensitizers. This narrative review describes the mechanisms, delivery systems, photosensitizers, and available evidence regarding the potential of PDT as a novel therapeutic approach for GBM.
