Ten tips to manage oral anticoagulation in hemodialysis patients with atrial fibrillation.

Patients with chronic kidney disease (CKD) have a high incidence and prevalence of atrial fibrillation (AF). While general treatment strategies for AF may largely be transferred to patients with mild to moderate CKD, patients with advanced CKD-particularly hemodialysis (HD) patients-with AF pose substantial therapeutical challenges to cardiologists and nephrologists. The arguably greatest dilemma is the very limited evidence on appropriate strategies for prevention of stroke and systemic embolism in HD patients with AF, since the risk for both thromboembolic events without oral anticoagulation and severe bleeding events with oral anticoagulation are substantially increased in advanced CKD, compared with the general population.

Urbanization reduces diversity, simplifies community and filter bird species based on their functional traits in a tropical city.

Understanding how organisms are coping with major changes imposed by urban intensification is a complex task. In fact, our understanding of the impacts of urbanization on biodiversity is scarce in the global south compared to the north. In this study, we evaluated how bird communities are affected by impact of urban intensification in a tropical city.

Trophic position determines the persistence of neotropical understory birds after forest disturbance.

Habitat loss and degradation are key drivers of the current biodiversity crisis. Most research focuses on the question of which traits allow species to persist in degraded habitats. We asked whether a species' trophic position or niche width influences the resilience of species in degraded habitats and to what extent habitat degradation affects trophic interactions between species.
