The molecular mechanism of ferroptosis-induced spontaneous abortion based on bioinformatics approach.

Spontaneous abortion (SA) is a prevalent placental dysfunction, and ferroptosis may play a crucial role in placental dysfunction and the development of SA. In this study, we employed data mining and analysis techniques to investigate the biological mechanism of SA induced by ferroptosis, resulting in the identification of a total of 79 ferroptosis-related genes in SA were identified. Among them, 3 co-expression modules of ferroptosis risk genes, ten significant functions and six biologically significant pathways were obtained 61 pairs of differentially expressed miRNA-ferroptosis factor relationships were identified, and WIPI1 and GSN were expressed at significantly higher levels in SA.

Genetic Analysis of 1p36 Deletions for Six Aborted Fetuses.

Context: Chromosomal abnormalities in embryos are the most common cause of early spontaneous abortions. Chromosome 1p36 deletion syndrome (OMIM 607872) is the most common subtelomeric, terminal microdeletion syndrome.

Objective: The study intended to analyze miscarriage samples using chromosomal microarray analysis (CMA), to explore the mechanism of chromosomal aberrations, and to identify the recurrence risk and a prenatal diagnostic strategy for couples experiencing spontaneous abortions.

Association between fetal chromosomal abnormalities and the frequency of spontaneous abortions.

Fetal chromosomal abnormalities are a common cause of spontaneous abortion. The present study investigated the association between fetal chromosomal abnormalities and the frequency of spontaneous abortions to enable clinicians to provide more informed genetic counseling. A total of 182 patients with a history of spontaneous abortions were recruited from July 2015 to August 2017.

Safety and Efficacy of Combined Oral Contraceptive Ethinyl Estradiol/Drospirenone (YAZ) in Chinese Women: A Single-Arm, Open-Label, Multicenter, Post-Authorization Study.

Introduction: The study was conducted to assess the safety and efficacy of a combined oral contraceptive, YAZ, containing 3 mg drospirenone/20 μg ethinyl estradiol administered in a 24/4 regimen.

Methods: This was a single-arm, open-label, interventional, post-authorization safety surveillance study of YAZ across 6 treatment cycles. Primary objective was assessing its safety profile in Chinese women.
