Direct Oral Anticoagulants Versus Warfarin in Patients With Isolated Heparin-Induced Thrombocytopenia or Heparin-Induced Thrombocytopenia With Thrombosis.

No existing studies compare oral anticoagulants to treat heparin-induced thrombocytopenia with or without thrombosis (HIT/HITT). This retrospective study evaluated thrombotic and bleeding outcomes in adults treated for HIT/HITT with a direct oral anticoagulant (DOAC) or warfarin between 2012 and 2023 within the Ochsner Health System. Patients with mechanical heart valves, valvular atrial fibrillation, antiphospholipid syndrome, active malignancy, or venous thromboembolism (VTE) within the previous 6 months were excluded.

Effect of correcting iron deficiency on the risk of serious infection in heart failure: Insights from the IRONMAN trial.

Aims: Concerns exist that intravenous (IV) iron might increase the risk of infections. The IRONMAN trial provided an opportunity to investigate whether giving IV ferric derisomaltose (FDI) to patients with heart failure and iron deficiency alters the rate of hospitalization or death due to infections.

Methods And Results: IRONMAN was a randomized trial of IV FDI versus usual care in patients with symptomatic heart failure, left ventricular ejection fraction (LVEF) ≤45%, and transferrin saturation (TSAT) <20% or ferritin <100 μg/L.

Optimization of SARS-CoV-2 culture from clinical samples for clinical trial applications.

Unlabelled: Clinical trials of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) therapeutics often include virological secondary endpoints to compare viral clearance and viral load reduction between treatment and placebo arms. This is typically achieved using quantitative reverse-transcriptase PCR (RT-qPCR), which cannot differentiate replicant competent virus from non-viable virus or free RNA, limiting its utility as an endpoint. Culture-based methods for SARS-CoV-2 exist; however, these are often insensitive and poorly standardized for use as clinical trial endpoints.

The human gut microbiome in health and disease: time for a new chapter?

The gut microbiome, composed of the colonic microbiota and their host environment, is important for many aspects of human health. A gut microbiome imbalance (gut dysbiosis) is associated with major causes of human morbidity and mortality. Despite the central part our gut microbiome plays in health and disease, mechanisms that maintain homeostasis and properties that demarcate dysbiosis remain largely undefined.
