24-Hour Compared With 12-Hour Mifepristone-Misoprostol Interval for Second-Trimester Abortion: A Randomized Controlled Trial.

Objective: To compare 24-hour and 12-hour mifepristone-to-misoprostol intervals for second-trimester medication abortion.

Methods: We conducted a prospective randomized controlled trial. Participants were allocated to receive mifepristone either 24 hours or 12 hours before misoprostol administration.

The association between uterine scar defect (niche) and the presence of symptoms.

Research Question: Is there association between the presence of a uterine niche and the presence of symptoms?

Design: This cross-sectional study was conducted at a single tertiary medical centre. All women who underwent Caesarean section from January 2017 to June 2020 were invited to the gynaecological clinics, and requested to complete a questionnaire regarding symptoms related to the presence of a niche (heavy menstrual bleeding, intermenstrual spotting, pelvic pain, infertility). Transvaginal two-dimensional ultrasonography was performed to assess the uterus and uterine scar characteristics.

Endometrioma increases the risk of antibiotic treatment failure and surgical intervention in patients with pelvic inflammatory disease.

Objective: To evaluate the outcome of pelvic inflammatory disease (PID) in patients with endometriosis with and without ovarian endometrioma.

Design: A retrospective cohort study.

Setting: A single university-affiliated tertiary center.

Fluctuation-Induced Interaction in Turbulent Flows.

Fluctuation-induced forces are observed in numerous physical systems spanning from quantum to macroscopic scale. However, there is as yet no experimental report of their existence in hydrodynamic turbulence. Here, we present evidence of an attraction force mediated via turbulent fluctuations by using two walls locally confining 2D turbulence.
