Anticoagulation therapy for the prevention of subclinical leaflet thrombosis after transcatheter aortic valve replacement: A comprehensive literature review and future directions.

Leaflet thrombosis after transcatheter aortic valve replacement (TAVR) presents a significant challenge, leading to adverse clinical outcomes. Subclinical leaflet thrombosis (SLT) is increasingly recognized, and there is a growing concern about its role in clinical events and hemodynamic valve deterioration. Current recommendations for prophylactic anticoagulation or antiplatelet therapy following TAVR are primarily based on expert consensus rather than definitive evidence from randomized trials, resulting in a variety of antithrombotic strategies in clinical practice.

A review of clopidogrel resistance in lower extremity arterial disease.

Objective: Lower extremity arterial disease (LEAD) is a prevalent condition that produces a significant burden on health care systems. Patients with LEAD have an increased risk of major adverse cardiovascular events as well as major adverse limb events. Despite significant variation in guidance on antiplatelet therapy for LEAD worldwide, many governing bodies recommend clopidogrel as the preferred single anti-platelet agent.

Associations between fecal glucocorticoid levels and social bonds vary with relatedness in juvenile rhesus macaques.

Strong social bonds in gregarious adult animals have been associated with lower levels of glucocorticoids. However, similar research is lacking for juvenile primates. We examined relationships between social bonds and mean concentrations of fecal glucocorticoid metabolites (fGCMs) in 44 free-ranging juvenile rhesus macaques (Macaca mulatta) on Cayo Santiago, Puerto Rico.
