Pop-off mechanisms in fetal megacystis: extravasation, umbilical cord cyst, ureterocele and megaureter.

Objective: To analyze comprehensively the incidence, antenatal ultrasound characteristics and prognostic implications of antenatal pop-off mechanisms of the fetal urinary system in pregnancies with suspected fetal megacystis.

Methods: This was a retrospective multicenter study of pregnancies with suspected fetal megacystis conducted across all academic hospitals in The Netherlands. Three antenatal pop-off mechanisms were identified: presence of an umbilical cord cyst (UCC), extravasation of urine into the intraperitoneal space (ascites) or perirenal subcapsular (urinoma), and megaureter/ureterocele.

Association of Constipation with Modes of Delivery: A Retrospective Questionnaire-based Study.

Introduction And Hypothesis: Pelvic floor damage can contribute to pelvic floor dysfunction, including constipation. Most studies focus on constipation during pregnancy, whereas information regarding the mode of delivery in relation to constipation is limited. We hypothesise that women with a history of vaginal delivery report constipation more often than women with a history of caesarean section.

Age-specific reference scores for the PISQ-12 on female sexual functioning in the Netherlands: a retrospective population-based survey.

Background: Female sexual dysfunction is common in the general population, with age emerging as a significant determinant of sexual activity and functioning.

Aim: To establish age-specific reference scores for the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire (PISQ-12) in the general Dutch female population.

Methods: A retrospective, cross-sectional, questionnaire-based study was conducted in the Netherlands.

A More Comfortable Method for Hydrostatic Weighing: Head above Water at Total Lung Capacity.

Hydrostatic weighing (HW) requires full submersion with the lungs at residual volume (RV) which is uncomfortable. Therefore, the purpose of this study was to find a more comfortable way to complete HW. A HW system was used to complete three comparisons: comparison 1: change in head position (head above water vs.

Monolithically-stacked thin-film solid-state batteries.

The power capability of Li-ion batteries has become increasingly limiting for the electrification of transport on land and in the air. The specific power of Li-ion batteries is restricted to a few thousand W kg due to the required cathode thickness of a few tens of micrometers. We present a design of monolithically-stacked thin-film cells that has the potential to increase the power ten-fold.
