Effects of Supervised Exercise on the Development of Hypertensive Disorders of Pregnancy: A Systematic Review and Meta-Analysis.

Hypertensive disorders of pregnancy (HDP) are the most common medical complication in pregnancy, affecting approximately 10-15% of pregnancies worldwide. HDP are a major cause of maternal and perinatal morbidity and mortality, and each year, worldwide, around 70,000 mothers and 500,000 babies die because of HDP. Up-to-date high-quality systematic reviews quantifying the role of exercise and the risks of developing HDP are currently lacking.

Nitric oxide positively affects endometrial receptivity via FAAH and NAPE-PLD .

Objective: To determine if models of human 'receptive' and 'non-receptive endometrium' differ in their responses to nitric oxide (NO) supplementation by measuring the levels of the enzymes of the endocannabinoid system (ECS) (fatty acid amide hydrolase (FAAH) and N-acylphosphatidylethanolamine-specific phospholipase D (NAPE-PLD)), which control the 'anandamide tone' essential for successful pregnancy.

Design: A study of FAAH and NAPE-PLD expression (using human endometrium) through the menstrual cycle and an using a model of 'receptive' (Ishikawa) and 'non-receptive' (HEC-1A) human endometrial cell lines treated with the NO-donating compound S-nitroso-N-acetylpenicillamine (SNAP).

Results: Immunoreactivity measured by optimised H-score for both FAAH and NAPE-PLD was reduced in secretory (receptive) endometrium compared to proliferative (non-receptive) endometrium ( = 0.

Association of maternal lipid profile and gestational diabetes mellitus: A systematic review and meta-analysis of 292 studies and 97,880 women.

Background: Gestational Diabetes Mellitus (GDM) is the most prevalent metabolic disorder during pregnancy, however, the association between dyslipidaemia and GDM remains unclear.

Methods: We searched Medline, Scopus, Web of Science, Cochrane, Maternity and Infant Care database (MIDIRS) and ClinicalTrials.gov up to February 2021 for relevant studies which reported on the circulating lipid profile during pregnancy, in women with and without GDM.

Of mice and (wo)men: factors influencing successful implantation including endocannabinoids.

BACKGROUND One in six couples suffer from infertility problems requiring in vitro fertilization therapy; however, the average birth rates in the past decade per IVF-embryo transfer cycle have remained static at around 25%. Although implantation failure is considered a major cause of infertility in otherwise healthy women, inadequate uterine receptivity is considered to be responsible for only two-thirds of implantation failures and problems with the embryo itself are responsible for the other third, such that only 30% of oocytes that are contacted by sperm result in successful human term pregnancies. Due to technical and ethical considerations, most research into the factors affecting the success of embryo implantation has been performed in mice, but this may be less than ideal.
