Navigating the gut-bone axis: The pivotal role of Coprococcus3 in osteoporosis prevention through Mendelian randomization.

Osteoporosis (OP) constitutes a notable public health concern that significantly impacts the skeletal health of the global aging population. Its prevalence is steadily escalating, yet the intricacies of its diagnosis and treatment remain challenging. Recent investigations have illuminated a profound interlink between gut microbiota (GM) and bone metabolism, thereby opening new avenues for probing the causal relationship between GM and OP.

Periconceptional Folic Acid Supplementation and the Risk of Spontaneous Abortion among Women Who Prepared to Conceive: Impact of Supplementation Initiation Timing.

It is unclear whether periconceptional folic acid (FA) supplementation decreases the risk of spontaneous abortion (SA). The impact of supplementation initiation timing has not been ascertained. This cohort study aimed to investigate the association between maternal periconceptional FA supplementation and risk of SA, with due consideration of the supplementation initiation timing.

Objectives: To explore the intentions of working-age internal migrants concerning their place of residence in old age and the relevant influencing factors.

Method: A cross-sectional survey was conducted in the 17 districts of Shanghai, China in 2013. Through multi-stage stratified sampling with probability proportional to size, 7968 internal migrants (aged 15-64 years) were selected and interviewed individually face to face.

Longitudinal Trends of AMS and IIEF-5 Scores in Randomly-Selected Community Men 40 to 80 Years Old: Preliminary Results.

Introduction: Most of conclusions on the relationship between age and reproductive health in aging men relied on cross-sectional data.

Aim: To better characterize the natural degradation trajectory of reproductive health of aging men based on longitudinal data.

Methods: A community cohort study was performed in randomly selected men 40 to 80 years old, initiated in 2012 and followed up in 2014 and 2016.

[Clinical study of exercise rehabilitation and gait analysis during the perioperative period of lumbar percutaneous transforaminal endoscopic discectomy].

Objective: To explore the clinical effect of exercise rehabilitation during perioperative period on residual pain, gait and activities of daily living (ADL) in patients with lumbar spinal stenosis (LSS) after lumbar percutaneous transforaminal endoscopic discectomy(PTED).

Methods: The clinical data of 48 patients with LSS underwent PTED from December 2015 to December 2016 were retrospectively analyzed. Patients were divided into observation group and control group according to different rehabilitation patterns, being 24 cases in each group.

The impact of age, BMI and sex hormone on aging males' symptoms and the international index of erectile function scores.

Objective: To analyze the impact of age, BMI and sex hormone on aging males' symptoms (AMS) and the 5-item version of the international index of erectile function (IIEF-5) scores in middle-aged and elderly Chinese men.

Methods: A population-based cross-sectional study was conducted in Jiashan County. A total of 969 men, aged between 40 and 80 years old, were admitted.

Single or double semen samples: the dilemma in epidemiological studies on semen quality.

Study Question: Is it necessary to collect more than one semen sample from each individual in epidemiological studies?

Summary Answer: Single semen samples can be used in model construction as long as the model adjusts for major relevant covariates.

What Is Known Already: If a series of semen samples are taken from one individual at different times, significant intra-individual variation may exist.

Study Design, Size, Duration: A population-based cross-sectional study was conducted from 1 December 2000 to 20 November 2002.

Cancer risks in parents who had a child with a congenital malformation.

Cancer risk in parents may be related to congenital malformations (CMs) in their children if they share genetic susceptibility or environmental exposure that may be teratogenic and carcinogenic. We conducted a population-based cohort study based on Danish register data. We identified 795,607 mothers and 781,424 fathers who had all their children between 1977 and 2007 in Denmark.

Turning point of age for semen quality: a population-based study in Chinese men.

Objective: To explore the relationship between age and semen quality in Chinese men.

Design: Population-based cross-sectional study.

Setting: The Department of Reproductive Epidemiology and Social Science, Shanghai Institute of Planned Parenthood Research, People's Republic of China.

[Association between age and quality of semen in Chinese males with normal fertility].

Objective: To explore the association between age and variables of semen in Chinese males with normal fertility.

Methods: The population size under study would consist of 946 fertile male volunteers from 6 provinces of China, aged between 20 and 59. Semen quality was analyzed by hand on site and background information was obtained through structured questionnaire.

Do reproductive hormones explain the association between body mass index and semen quality?

Aim: To examine whether reproductive hormones play a role in the association between body mass index (BMI) and semen quality.

Methods: Semen quality and testosterone (T), luteinizing hormone (LH), follicle-stimulating hormone (FSH) and estradiol (E(2)) were evaluated in 990 fertile males with age 38.9 +/- 9.
