Objective: The aim of this study was to compare the efficacy and safety of a prostaglandin E(2) (PGE(2)) vaginal insert with those of oxytocin for labor induction. The present study also examined whether its use reduces the rate of cesarean delivery in term pregnancies with premature rupture of membranes (PROM) and low Bishop scores.
Materials And Methods: A total of 240 women with singleton pregnancies at >or= 37 weeks, no prior uterine scar, vertex presentations, reactive nonstress tests, PROM for >or= 12 hours and Bishop scores of
Results: The time from labor induction to active labor onset was significantly shorter in the oxytocin group than in the PGE(2) group (4.9 +/- 4.1 vs. 8.5 +/- 3.6 hours; p = 0.02). The time from induction to delivery was also significantly shorter in the oxytocin group (3.4 +/- 1.5 vs. 9.6 +/- 4.7 hours; p = 0.02). Cesarean delivery rates were statistically similar in the oxytocin and PGE(2) groups (18.3 vs. 20.0%; p = 0.81). Neonatal outcomes were comparable in both groups. Comparable results were observed for nulliparous women included in the study population.
Conclusion: Oxytocin treatment seems to be superior to vaginal administration of PGE(2) to induce labor in term pregnancies complicated with PROM and unfavorable services.

Preinduction cervical ripening in previous caesarean pregnancy is limited to intracervical Foley catheter. This study is aimed at finding the vaginal birth rates, improvement of Bishop score, and safety of osmotic dilator (Dilapan-S) among women with previous caesarean pregnancy. We conducted this single-group clinical study after the approval of the institute ethics committee, clinical trial registration, and obtaining informed consent.

Mothers encounter several challenges to sustain breastfeeding until the recommended 6 months of age. There is limited evidence on the impact of women's labor pain experiences upon cessation of breastfeeding. We aimed to investigate the association between women's labor pain experiences, intrapartum interventions, and pre-birth psychological vulnerabilities and cessation of breastfeeding.

Integrative studies of diverse neuronal networks that govern social behavior are hindered by a lack of methods to record neural activity comprehensively across the entire brain. The recent development of the miniature fish Danionella cerebrum as a model organism offers one potential solution, as the small size and optical transparency of these animals make it possible to visualize circuit activity throughout the nervous system. Here, we establish the feasibility of using Danionella as a model for social behavior and socially reinforced learning by showing that adult fish exhibit strong affiliative tendencies and that social interactions can serve as the reinforcer in an appetitive conditioning paradigm.

Purpose: To determine the reference values for the shock index (SI) in postpartum patients undergoing elective cesarean delivery with regional anesthesia.
Methods: This prospective study was conducted at our tertiary center between August 1, 2023, and March 1, 2024. We calculated the reference values for the SI within the first 48 h postpartum for patients who underwent elective cesarean delivery after the 34th week of gestation.

Medications to treat substance use disorders remain suboptimal or, in the case of stimulants and cannabis, non-existent. Many factors have contributed to this paucity, including the biological complexity of addiction, regulatory challenges, and a historical lack of enthusiasm among pharmaceutical companies to commit resources to this disease space. Despite these headwinds, the recent opioid crisis has highlighted the devastating consequences of SUDs for both individuals and society, stimulating urgent efforts to identify novel treatment approaches.
