Multivariable prediction models for fetal macrosomia and large for gestational age: A systematic review.

Background: The identification of large for gestational age (LGA) and macrosomic fetuses is essential for counselling and managing these pregnancies.

Objectives: To systematically review the literature for multivariable prediction models for LGA and macrosomia, assessing the performance, quality and applicability of the included model in clinical practice.

Search Strategy: MEDLINE, EMBASE and Cochrane Library were searched until June 2022.

Routine use of cell salvage during cesarean section: A practice evaluation.

Introduction: Intraoperative cell salvage is a well-documented alternative to donor blood transfusion given the scarcity of donor blood pools and the incumbent risk of allogenic blood transfusion. Its use in obstetrics has been limited by concern over fetal alloimmunization due to the risk of fetomaternal hemorrhage. However, there are a paucity of studies reporting on outcome.

Inaccuracies in plasma oxytocin extraction and enzyme immunoassay techniques.

Numerous studies have reported extensive associations between plasma oxytocin (OXT) concentrations and various human physiological and neurobehavioral processes. Measurement of OXT is fraught with difficulty due to its low molecular weight and plasma concentrations, with no consensus as to the optimal conditions for pre-analytical sample extraction, standards for immunoassay validation or the ideal protease inhibitors to prevent OXT degradation. Previous attempts at determining the efficacy of various purification techniques such as solid phase extraction (SPE) or ultrafiltration have only utilized human plasma samples, making it difficult to dissect out whether the effect of interference comes from the extraction process itself or cross-reactivity with other proteins.

Septic Shock Immediately following Percutaneous Suprapubic Catheterization.

Suprapubic catheterization (SPC) is considered a safe and effective procedure for long-term bladder decompression. With proper technique and appropriate patient selection, significant complications of SPC are rare. Immediate postoperative septic shock (i.
