Twice-Weekly Versus Once-Weekly Membrane Sweeping in the Prevention of Post-Term Pregnancy: a Systematic Review and Meta-Analysis of Randomized Controlled Trials.

Membrane sweeping is considered a simple and effective method for initiating spontaneous onset of labor. Despite the widely accepted membrane sweeping use to prevent post-term birth, the optimal frequency has not been estimated. We aimed to assess the effectiveness and safety of twice-weekly versus once-weekly membrane sweeping in post-term pregnancy prevention. Four different databases were searched for available clinical trials from inception to October 2022. We selected randomized controlled trials (RCTs) that compared twice-weekly membrane sweeping in intervention group versus once-weekly membrane sweeping in control group among pregnant women with singleton pregnancy at ≥ 39 gestational weeks. Our primary outcomes were the rate of spontaneous onset of labor and the requirement for formal methods of labor induction. Our secondary outcomes were sweeping to delivery interval in days, gestational age at delivery in weeks, Bishop score at admission, chorioamnionitis, and premature rupture of membranes. Three RCTs (596 patients) were included. Twice-weekly membrane sweeping was associated with significant increase in the rate of spontaneous onset of labor and significant decline in labor induction rate in comparison with once-weekly group. Duration from sweeping to delivery was significantly shorter among the twice-weekly group (p<0.001). Furthermore, gestational age at delivery was significantly earlier in the twice-weekly group. A significantly higher Bishop score at admission was observed in the twice-weekly group (p=0.02). There were no significant differences across both groups in chorioamnionitis and premature rupture of membranes. In conclusion, twice-weekly membrane sweeping is more effective in preventing post-maturity pregnancy than once-weekly sweeping without added adverse events.

Clinical significance of vit D and AMH and its correlation with polycystic ovarian parameters in obese and non-obese Egyptian women.

Women of reproductive age are frequently affected by the heterogeneous endocrine-metabolic conditions recognized as polycystic ovarian syndrome (PCOS). Moreover, FSH (Follicle-stimulating hormone), steroidogenesis, and LH (Luteinizing Hormone) are suppressed by the anti-Mullerian hormone, a good indicator of ovarian reserve, that is generated from granulosa cells. In the past ten years, vitamin D (VD) has attracted and maintained great interest in human health and biomedical research, particularly those about female reproductive-metabolic problems. Therefore, this study was designed to evaluate the correlation of VD and AMH with PCOS parameters in Egyptian women. Assessments were done on 35 control women and 45 PCOS sufferers. Utilizing the updated Rotterdam criteria, PCOS was identified. After recording anthropometric data, fasting serum levels of VD, follistatin (FST), insulin, FSH, LH, total testosterone (TT), sex hormone binding globulin (SHBG), as well as fasting plasma glucose (FPG), and the free androgen index (FAI) were measured in both groups. Compared to the control group, the PCOS group had a greater prevalence of hypovitaminosis D but serum levels of follistatin, LH, TT, AMH, insulin, and FPG, were considerably higher. Besides, there was a substantial inverse relationship between VD and the levels of follistatin, FPG, LH, TT, and AMH and a positive correlation with FSH in PCOS women's blood. This study revealed that hypovitaminosis D, elevated AMH, and FST may be regarded as alarming risk factors for PCOS in Egyptian women.
