Causal link between gut microbiota and osteoporosis analyzed via Mendelian randomization.

Objective: Osteoporosis (OP) is closely associated with gut microbiota (GM), yet the nature of their causal relationship remains elusive. Therefore, this study aims to reverse causality between GM and OP by using population cohorts and two-sample MR (TSMR) analysis.

Materials And Methods: In this study, we conducted an extensive genome-wide association study (GWAS) using publicly accessible summary statistics data for GM and OP.

Unraveling the connection between gut microbiota and Alzheimer's disease: a two-sample Mendelian randomization analysis.

Purpose: Studies have shown a close relationship between gut microbiota (GM) and Alzheimer's disease (AD). However, the causal relationship between them remains unclear.

Methods: We conducted a genome-wide association study (GWAS) using publicly available summary statistics data for GM and AD.

Diagnosing early scar pregnancy in the lower uterine segment after cesarean section by intracavitary ultrasound.

Background: Early scar pregnancy (CSP) in the lower uterine segment after cesarean section is a type of ectopic pregnancy that can cause major complications if left untreated. Transabdominal ultrasound is a common procedure but is influenced by external factors. Thus, intracavitary ultrasound may have better diagnostic efficiency for CSP.
