BACKGROUND: Endometriosis has been reported to be associated with metabolism-related diseases, such as hypercholesterolemia and diabetes, while no studies have reported the association between endometriosis and metabolic syndrome. OBJECTIVE: This study aims to explore the association between endometriosis and metabolic syndrome. Also, the association between endometriosis and single metabolic syndrome indicator was explored. METHODS: This was a cross-sectional study based on the National Health and Nutrition Examination Survey (NHANES)...

OBJECTIVES: To assess the prevalence of metabolic syndrome (MetS) and its components in Chinese women with premature ovarian insufficiency (POI) and to explore the metabolic profile of Chinese women with POI. METHODS: 118 POI women aged 20-38 years and 151 age-and-BMI-matched control women were recruited. Measurements included body height, weight, waist circumference (WC), hip circumference (HC), blood pressure, follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), triglycerides (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), fasting plasma glucose (FPG) and fasting insulin (FINS)...

Oral contraceptives are among the most commonly used contraceptive methods. However, Italian women underused reliable hormonal contraceptives as compared with other European women. There is a need to streamline access to oral contraception, with expected benefits on emotional well-being of women and potential savings for health system in Italy. Indeed, women can only access to oral contraceptives through mandatory medical prescription. This is one of the most important barrier experienced by women. We hereby provide an expert opinion on the potential reclassification, extending pharmacy services to include responsible and appropriate use of POP, as an opportunity also in Italy to increase the use of safe and effective contraceptive methods...

OBJECTIVE: ERα (estrogen receptor alpha) exerts nuclear genomic actions and membrane-initiated non-genomic effects. The mutation of aspartic acid into alanine in vitro revealed the critical role of aspartic acid 258 (corresponding to mouse amino acid site 262) of ERα for non-nuclear function. Our previous in vitro study revealed that this mutation blocked estrogen's non-genomic effects on vascular endothelial H2 S release. Here, we studied the in vivo role of the aspartic acid 262 of ERα in the reproductive system and in the vascular tissue...

AIMS: To explore suggestions for clinicians on the most effective treatment for hydrosalpinx undergoing IVF-ET. MATERIALS AND METHODS: We reviewed 936 women with hydrosalpinx and 6715 tubal infertile women without hydrosalpinx who underwent IVF/ICSI between January 2014 and August 2019 in our center. Hydrosalpinx patients received different treatments including laparoscopic surgery (only salpingectomy and proximal tubal occlusion/ligation were included), ultrasonic-guided aspiration and hysteroscopic tubal occlusion...

OBJECTIVE: To evaluate whether Zi Gui Nv Zhen capsules (ZGNZC) can increase the fertility rate of Chinese women with infertility due to thin endometrium. METHODS: Prospective, randomized, open-labeled 3-monthly study; 104 patients (aged 20-40 years) receiving either ZGNZC (experimental group, n  = 55) or not (control group, n  = 49). Main outcomes: thickness/type of the endometrium during ovulation and pregnancy rate. Between-group analysis (A) compares the experimental vs...

OBJECTIVE: Neonatal outcomes in women with and without medically managed gestational diabetes mellitus (GDM) were compared after accounting for differences in maternal baseline characteristics using a propensity score (PS) analysis. METHODS: Women without preexisting diabetes, delivering singletons during 2010-2017 in a large hospital, were eligible for inclusion. Using nearest-neighbour PS matching, women with non-pharmacological managed GDM were matched with women whose GDM was medically managed...

The debate about contraception has become increasingly important as more and more people seek safe and effective contraception. More than 1 billion women of reproductive age worldwide need a method of family planning, and wellbeing, socio-economic status, culture, religion and more influence the reasons why a woman may ask for contraception. Different contraceptive methods exist, ranging from 'natural methods' (fertility awareness-based methods - FABMs) to barrier methods and hormonal contraceptives (HCs). Each method works on a different principle, with different effectiveness...

OBJECTIVE: To investigate the physiological changes of serum homocysteine (Hcy) levels and to establish trimester-specific reference intervals of serum Hcy levels for Chinese pregnant women. METHOD: According to the guideline of the Clinical and Laboratory Standards Institute (CLSI) C28-A3 document, 476 healthy women were recruited in West China Second University Hospital, Sichuan University from January 2021 to October 2021. Among them, 120 were non-pregnant, 118 were in the first trimester, 120 were in the second and 118 were in the third trimester of gestation...

OBJECTIVE: Endometriosis (EMS) is an estrogen-dependent condition with unclear pathogenesis. Recent findings suggest implicate autophagy and ferroptosis in EMS development. METHODS: We assessed autophagy and ferroptosis proteins in EMS patients using immunohistochemistry and western blot and established an EMS rat model through allograft endometrial transplantation, confirmed via hematoxylin and eosin staining and epithelial-mesenchymal transition -related proteins...

OBJECTIVE: To analyze pregnancy outcomes of women with one abnormal value (OAV) during oral glucose tolerance test (OGTT) or OGTT-intolerance, compared with gestational diabetes mellitus (GDM) and normal glucose tolerance (NGT) pregnant women, according to whether they received any health intervention or not. METHODS: An observational retrospective study was designed including pregnant women who gave birth at Hospital del Mar, Barcelona (Spain) during December/2014-July/2018...

OBJECTIVE: This study elucidated the efficacy of Relugolix (REL) on the reduction of uterine volume and clinical symptoms for the treatment of adenomyosis. METHODS: We conducted a retrospective cohort study of patients who received REL (40 mg for about 20 weeks) and who underwent a hysterectomy for adenomyosis or fibroids. We divided patients into two groups: adenomyosis coexisting with fibroids (Group A) and fibroids only (Group B); the groups were determined by a postoperative pathological examination...

OBJECTIVE: Though recent studies have pointed out different manifestations between obese and nonobese patients with polycystic ovarian syndrome (PCOS), there is no clear evidence to confirm this viewpoint. Therefore, the metabolic characteristics of obese and nonobese patients with PCOS were systematically compared through meta-analysis in this study. METHODS: Data were searched from PubMed, Web of Science, Embase, Cochrane Library, CNKI, and Wanfang databases. Articles on obese and nonobese patients with PCOS published from database inception to January 2022 were included...

Unilateral non-hemorrhagic adrenal infarction (NHAI) is a very uncommon cause of acute abdomen in pregnancy. Diagnosis is highly challenging due to its rarity, heterogeneity of clinical presentation, and inconclusiveness of the initial workup. Timely recognition is pivotal to ensuring optimal outcomes. Here we describe a case of spontaneous unilateral NHAI diagnosed in a singleton pregnant woman at 32 weeks' gestation at our centre and provide the findings of an extensive literature review on the topic. We identified 22 articles describing 31 NHAI cases in 30 obstetric patients: NHAI occurs more frequently on the right side and in the third trimester, and diagnosis is formulated more than 24 h after clinical presentation in 50% of cases; second-level imaging is always necessary to reach a definitive diagnosis and start appropriate treatment...
