Introduction Dienogest (DNG) was demonstrated to be comparable to gonadotropin-releasing hormone agonist (GnRH-a) in controlling symptoms of endometriosis. GnRH-a is used before in vitro fertilization (IVF) in women with endometriosis to improve pregnancy outcomes. We aimed to determine the effect of DNG pretreatment on IVF outcomes, including number of mature oocytes, rate of clinical pregnancies, and rate of live births in women with endometriosis. Methods All studies involving DNG, IVF and endometriosis were searched from the PubMed, Ovid/MEDLINE, Wanfang, CQVIP, China National Knowledge Infrastructure databases and ClinicalTrials...

INTRODUCTION: The uterine caesarean scar defect, also known as uterine niche or isthmocele, is an irregularity in the anterior uterine wall at the site of a previous cesarean section scar. It is associated with obstetrical complications such as caesarean scar ectopic pregnancy, uterine rupture and, the placental accreta spectrum. Women with cesarean scar defects are frequently asymptomatic, but they may also experience abnormal vaginal bleeding, chronic pelvic pain, and infertility. METHODS: This systematic review aims to determine the best hysterotomy closure technique to prevent subsequent development of uterine scar defects...

OBJECTIVES: Midurethral slings are considered the gold standard for the surgical treatment of stress-urinary incontinence (SUI), with an efficacy up to 80%. Another therapeutic option is the use of bulking agents, which create an artificial mass into the urethral submucosa, with an efficacy varying from 64% to 74%. Although bulking agents have a lower risk of complications than midurethral sling surgery, they are mainly used in case a midurethral sling is not an option or if midurethral sling surgery failed to cure stress urinary incontinence...

OBJECTIVE: Chemoresistance in ovarian cancer results in treatment failure, yet underlying mechanisms that regulate chemoresistance remain largely unclear. There is emerging evidence relating ovarian cancer drug resistance with bioactive sphingolipids and regulation of sphingolipid metabolism. This work investigated the expression and function of ceramide kinase (CerK), a lipid kinase that regulate central bioactive sphingolipids, in ovarian cancer, as well as the therapeutic potential of targeting CERK...

Objective Gestational Trophoblastic Diseases (GTD) comprise a group of rare diseases originating from the trophoblast, affecting women of child-bearing age. Providing optimal information to patients with a rare disease is challenging, because of the small number of patients and limited clinical expertise of many healthcare professionals. Both knowledge and lack of knowledge in patients may influence illness perception. We investigated whether a web-based interactive intervention influences illness perception and knowledge in women with GTD...

Background Adenomyosis is an estrogen-dependent gynecologic condition that can cause pain symptoms, heavy menstrual bleeding, and infertility. Several treatments, including hormonal therapy can improve patients' quality of life through alleviating symptoms. Dienogest (DNG), a 19-norsteroid derivative oral progestin, is a promising treatment option for adenomyosis. Objectives This review aims to summarize the clinical outcomes (efficacy and adverse events) of DNG treatment for symptomatic adenomyosis compared with other hormonal treatments, discuss the mechanism underlying adverse events, and identify future challenges...

OBJECTIVES: Nocturia was commonly treated with drugs burdened with high costs and numerous side effects; in fact, more than 70% of patients drop out of long-term treatment. Protopine and Nuciferine are two alkaloids that have different effects on the neurotransmitter receptors involved in the regulation mechanism of the onset of urinary stimuli. The aim of the study is to evaluate the efficacy in controlling primarily nocturia and secondarily urgency and dysuria after three months of treatment with combination therapy of protopine and nuciferine syrup...

OBJECTIVES: Metformin decreased circulating levels of anterior pituitary hormones and its effect on thyrotropin concentration was found to be stronger in individuals receiving myo-inositol. Phospholipids containing inositols are precursors of second messengers of several hormones, including gonadotropins and insulin. The aim of the current study was to investigate whether the concomitant use of myo-inositol changes the effect of metformin on gonadotropin levels. DESIGN: A prospective observational study...

INTRODUCTION: Unicornuate uterus is a rare Müllerian anomaly. Its potential association with a rudimentary uterine horn can cause a diagnostic delay. The most common consequences are pelvic pain, hematometra and endometriosis. Diagnosis of a unicornuate uterus is usually done by imaging combining ultrasound (US) and Magnetic Resonance Imaging (MRI). The aim of this systematic review is to assess the role of laparoscopic approach in the management of this rare condition. METHODS: A comprehensive search was performed in PubMed, EMBASE, SCOPUS and Web of Science databases prior to 1 may, 2022 according to Preferred Reporting Items for Systematic Reviews and Meta- Analyses statement (PRISMA)...
