Comparison of the biomechanical effect of distal implants placed at different angles in the all-on-four technique: A nonlinear finite element analysis.

Introduction: The "All-on-four" technique addresses this by placing two vertical implants in the anterior region and two posterior implants angled up to 45°. This study evaluates stress distribution on bone, implants, abutments, gingiva, and prostheses based on posterior implant angulation, using both standard and angled neck implants. Additionally, angled neck implants were used alongside standard implants.

Prediction of Hepatocellular Carcinoma and Liver-related Events in Anti-hepatitis D Virus-positive Individuals.

Background & Aims: Chronic hepatitis D (CHD) is the most severe form of chronic viral hepatitis, with a high risk of developing hepatocellular carcinoma (HCC) and liver-related mortality. Risk stratification is needed to guide HCC surveillance strategies and to prioritize treatment with antiviral agents.

Methods: We conducted a multicenter retrospective cohort of anti-hepatitis D virus (HDV)-positive individuals managed at sites in the Netherlands and the United Kingdom.

The effect of genital self-image on sexual satisfaction and stress in women after vaginal delivery.

Objective: Pregnancy, childbirth, and postpartum periods bring along biological, psychological, and social changes that could affect women's sexual health. The aim of this study was to evaluate the effect of genital self-image on sexual satisfaction and stress in women who had a vaginal delivery.

Methods: This descriptive and cross-sectional study was conducted online between June and September 2023 by using snowball sampling and the data collection forms prepared in the GoogleDocs program.
