Low fetal fraction and adverse pregnancy outcomes- systematic review of the literature and metanalysis.

Purpose: While cell-free DNA (cfDNA) screening has emerged as a screening modality for common aneuploidies, further research and several publications over the past decade suggested some correlation between the low concentrations of cfDNA and a number of pregnancy-related complications. The primary goal of this systematic review and meta-analysis was to assess the potential value of low-ff levels in the prediction of subsequent PE/PIH, GDM, SGA/FGR, and PTB. The meta-analysis results aim at summarizing the currently available literature data and determining the clinical relevance of this biochemical marker and the potential necessity for additional investigation of its utility in complications other than the detection of common aneuploidies.

Persistent Postpartum Urinary Retention: A Case Report and Review of Literature.

This case report describes persistent urinary retention lasting over 30 days postpartum in a 23-year-old primiparous female after an otherwise uncomplicated vaginal delivery at 37 weeks gestation. Notable risk factors present included epidural anesthesia, episiotomy, third-degree perineal laceration, and inability to void spontaneously before leaving the delivery room. Despite initial catheterization draining a large volume, the patient experienced recurrent failed voiding trials requiring ongoing intermittent catheterization during her admission.

Cloacal type defect of the anal canal following an obstetric anal sphincter trauma.

Neglected severe obstetric anal sphincter injuries may result in fecal incontinence. It is of paramount importance to identify such injuries at the time of vaginal delivery and have appropriate surgical training for optimal anatomical restoration of the perineal structures.
