Induction of Labour with a Double Balloon Catheter - Comparison of Effectiveness of Six Versus Twelve Hours Insertion Time: a Prospective Case Control Study.

Introduction: Induction of labour is a common obstetric procedure to initiate or augment contractions when labour is delayed or uncertain. The double balloon catheter is a safe and effective mechanical method for cervical ripening during induction of labour. This study evaluates the effectiveness of reducing double balloon catheter insertion time from 12 to 6 hours. Methods: 248 women undergoing induction with a double balloon catheter at term were divided into two groups: catheter placed for 12 hours at 8 pm in the first half of 2021 (P12) and catheter placed for 6 hours at 7 am in the second half of 2021 (P6). T-tests, chi-squared tests, and Wilcoxon signed rank test were used for statistical analysis. Primary and secondary endpoints included induction to delivery interval, prostaglandin to delivery interval, mode of delivery, and maternal and neonatal outcomes. Results: The P6 group had a significantly reduced induction to delivery interval of 558 min (P6: 1348 min, P12: 1906 min, p < 0.01, 95% CI: 376-710) within demographically comparable groups. Multiparous women also showed a significant reduction in prostaglandin to delivery interval of 260 min (P6: 590 min, P12: 850 min, p = 0.038, 95% CI: 9-299). There were no significant differences in mode of delivery, maternal blood loss, or neonatal outcome. Conclusion: Reducing double balloon catheter placement time from 12 to 6 hours resulted in almost 9 hours less induction to delivery interval without adverse effects on maternal and neonatal outcome.

Mesh-augmented transvaginal repair of recurrent or complex anterior pelvic organ prolapse in accordance with the SCENIHR opinion.

INTRODUCTION AND HYPOTHESIS: To evaluate the performance of mesh-augmented repair of anterior pelvic organ prolapse (POP) with or without apical vaginal wall involvement in women with recurrent or complex prolapse. METHODS: This multicenter cohort study included women undergoing surgery with Calistar S (Promedon, Argentina) for anterior POP between 2016 and 2018. The SCENIHR opinion was considered for patient selection, surgeon's experience and choice of implant. Patients were prospectively invited to assess effectiveness and safety by anamnesis, validated questionnaires and pelvic examination. A composite endpoint defined by POP-Q ≤ 1, absence of a vaginal bulge symptom and repeated surgery for POP was used to define treatment success. Descriptive statistics were applied. McNemar or Wilcoxon signed rank tests were used as paired samples tests. The significance level was set at 5%. RESULTS: A total of 107 non-fertile women with a mean age of 70.6 years were enrolled. Ninety-three (86.9%) women presented with recurrent prolapse. The mean follow-up time was 18.5 months. Treatment success was achieved in 76% of cases according the composite endpoint, with 98% reaching POP-Q ≤ 1 and a significant improvement in quality of life (p < 0.001). Mesh exposure occurred in six (5.6%) patients, although none required further surgery. Four (3.7%) patients reported dyspareunia, and a single (0.9%) patient displayed a prominence due to mesh folding. CONCLUSIONS: Mesh-augmented repair of anterior POP is effective and safe in women with recurrent or complex prolapse. Hence, in a select patient population, the benefits of mesh-augmented POP repair still outweigh the risks.

Extracellular Matrix Components HAPLN1, Lumican, and Collagen I Cause Hyaluronic Acid-Dependent Folding of the Developing Human Neocortex.

Neocortical expansion, thought to underlie the cognitive traits unique to humans, is accompanied by cortical folding. This folding starts around gestational week (GW) 20, but what causes it remains largely unknown. Extracellular matrix (ECM) has been previously implicated in neocortical expansion and here we investigate the potential role of ECM in the formation of neocortical folds. We focus on three specific ECM components localized in the human fetal cortical plate (CP): hyaluronan and proteoglycan link protein 1 (HAPLN1), lumican and collagen I (collectively, HLC). Addition of HLC to cultures of human fetal neocortex (11-22 GW) caused local changes in tissue stiffness, induced CP folding, increased CP hyaluronic acid (HA), and required the HA-receptor CD168 and downstream ERK signaling. Importantly, loss of HA reduced HLC-induced and 22 GW physiological nascent folds. This was altered in samples with neurodevelopmental disorders, indicating it may be a useful system to study such disorders.
