Retrospective Analysis of Clinical Characteristics and Neonatal Outcomes of Pregnant Women with SARS-COV-2 Infection.

This retrospective study aimed to investigate the clinical characteristics and neonatal outcomes of pregnant women with SARS-COV-2 in Wuhan Children's Hospital and further suggested a possible management strategy for infected pregnant women under epidemic situation. In this study, 8 pregnant women with SARS-COV-2 who were admitted into Wuhan Children's Hospital, China from February 1, 2020 to March 30, 2020 and the clinical features, laboratory data, maternal and neonatal outcomes were analyzed. The mean age of the women at the time of admission was 30.

Associations between smoking, sex hormone levels and late-onset hypogonadism in men differ depending on age.

Few studies have investigated whether associations between smoking, sex hormone levels, and symptoms of late-onset hypogonadism (LOH) in men are affected by age. This multi-center, cross-sectional study involving 6,296 men aged 40-79 years was conducted between June 1, 2013 and August 31, 2016 in 6 provinces of China. Total testosterone, free testosterone, and Aging Males' Symptoms scale (AMS) scores were compared depending on smoking status and the number of cigarettes smoked.

The antifertility effectiveness of a novel copper-containing composite used in intrauterine contraceptive devices and the releasing behavior of cupric ions contained in the composite in rats.

Background: This study was conducted to investigate the antifertility effectiveness of a novel copper-containing composite used in intrauterine contraceptive devices (IUDs) that contain cupric chloride/silicon dioxide/poly(vinyl alcohol) (CuCl₂/SiO₂/PVA) and the releasing behavior of cupric ions in the composite into the serum and uterine fluid in rats.

Study Design: Two hundred and forty sexually mature female Sprague-Dawley rats were randomly divided into six groups: sham-operated control group (n=20), bulk copper group (Cu group, n=40), SiO₂/PVA group (n=40), CuCl₂/SiO₂/PVA groups I (n=40, copper ion was released from IUD at a rate of 5-10 mcg/220 mm² per day) and II (n=40, copper ion was released from IUD at a rate of 10-20 mcg/220 mm² per day), and normal control group (n=20). IUD was inserted into the uterus of rats after acclimatization of 1 week.
