Premenstrual symptoms are common problems among female high-school and college athletes. This prospective study investigated associations between sleep habits and interference of premenstrual symptoms in athletic performance among Japanese adolescent athletes. A school-based survey on menstruation and school life was conducted among 623 female high-school students in 2015 and 2016, and data from the two surveys were connected.

Study Objective: To investigate the relationships between premenstrual syndrome (PMS) and lifestyle, sleep, and dietary habits among Japanese high school students.
Design: Cross-sectional study.
Setting: Two public high schools in Sendai, the largest city in northeastern Japan.
Introduction: Premenstrual syndrome (PMS) comprises a range of mood, behavioural and physical symptoms, and impairs many women's quality of life. Isoflavones are expected to stabilise the natural fluctuation of the oestrogen cycle through their selective oestrogen receptor modulator-like activities that alleviate PMS symptoms. Equol, a metabolite of a soy isoflavone converted from daidzein by specific gut bacteria, has a greater bioavailability compared with other soy isoflavones.

Objectives: We reanalyzed these data to determine the positive effects of education on premenstrual symptoms.
Aim: Consumption of soy isoflavones reduces the risk of estrogen-related diseases, such as menopausal symptoms, osteoporosis, and cardiovascular disease. Equol is metabolized from the isoflavone daidzein by intestinal bacteria and has higher bioavailability than other isoflavones. Equol producers are believed to benefit from soybean consumption to a greater extent than non-producers.

Aim: Consumption of isoflavones, which are predominantly derived from soybeans, reduces the risk of estrogen-related diseases, such as menopausal symptoms, breast cancer, osteoporosis, and cardiovascular disease. Equol is more bioavailable than other soy isoflavones, and equol producers are believed to benefit to a greater extent. This study was conducted to evaluate the relation between premenstrual syndrome (PMS) and equol-production status in Japanese reproductive-age women.

A primiparous woman with a St Jude Medical (SJM) mitral valve prosthesis and receiving anticoagulant drug delivered a healthy male infant by spontaneous normal vaginal delivery. Oral warfarin was replaced by subcutaneous heparin at the 6th week of gestation and the dosage of heparin was adjusted to maintain a partial thromboplastin time between 2.0 and 2.
