Acarnus are poecilosclerid sponges characterized mainly by cladotylote megascleres. Five species are known on the Brazilian coast: Acarnus innominatus Gray 1867, Acarnus radovani (Boury-Esnault, 1973), Acarnus toxeata Boury-Esnault, 1973, Acarnus nicoleae van Soest, Hooper & Hiemstra, 1991 and Acarnus microxeatus Nascimento & Pinheiro, 2023. This study describes two new Brazilian species, Acarnus hooperi sp.

- The study investigates ancient microbiomes in archaeological dental calculus from 102 individuals across 10 Pacific islands and one island in Southeast Asia over ~3000 years, revealing insights into human migration patterns.
- DNA from oral microbiomes in dental calculus is better preserved than human DNA from bones, allowing for a clearer analysis of historical microbial communities.
- The oral microbial communities from the Pacific and Island Southeast Asia are distinct from those in Europe, Africa, and Asia, indicating that geographic factors influence the composition of these ancient microbiomes.
Background And Aims: Portal hypertension is the main pathophysiological driver of decompensation in patients with liver cirrhosis. Epithelial cell death markers, m30 and m65, correlate with hepatic injury and predict outcomes across various stages of liver disease. We aim (i) to evaluate whether portal hypertension itself contributes to liver outcome-relevant epithelial injury, and (ii) to analyse the capacity of m30/m65 to predict outcome in patients receiving a transjugular intrahepatic portosystemic shunt (TIPS) for refractory ascites.

- Trillions of microbes in the human mouth act as a crucial organ, but there's a lack of understanding about oral microbiomes in underrepresented ethnic groups in the U.S. like Hispanics, Blacks, and Asians.
- The study uses advanced sequencing to examine bacterial communities in saliva and plaque from 26 healthy individuals in South Florida, a culturally diverse area.
- Findings reveal notable differences in microbial composition based on factors like mouth location, sex, and gingival health, underscoring the importance of including a diverse range of populations in oral microbiome research.
Background: Short and rare episodes of atrial fibrillation (AF) are commonly detected using implanted devices (device-detected AF) in patients with prior stroke or transient ischemic attack (TIA). The effectiveness and safety of oral anticoagulation in patients with prior stroke or TIA and device-detected AF but with no ECG-documented AF is unclear.
Methods And Results: This prespecified analysis of the NOAH-AFNET 6 (Non-Vitamin K Antagonist Oral Anticoagulants in Patients With Atrial High Rate Episodes) trial with post hoc elements assessed the effect of oral anticoagulation in patients with device-detected AF with and without a prior stroke or TIA in the randomized, double-blind, double-dummy NOAH-AFNET 6 trial.
