Risk of autism spectrum disorder in offspring following paternal use of selective serotonin reuptake inhibitors before conception: a population-based cohort study.

Objective: The present study aimed to examine the association between paternal selective serotonin reuptake inhibitor (SSRI) use before conception and the risk of autism spectrum disorder (ASD) in offspring.

Design: A population-based cohort study.

Methods: We conducted a cohort study of 669 922 children born from 1998 to 2008, with follow-up throughout 2013.

Prenatal exposure to β2-adrenoreceptor agonists and the risk of autism spectrum disorders in offspring.

Purpose: We aimed to examine the risk of autism spectrum disorders (ASDs) in the offspring who were exposed to maternal use of β2-adrenoreceptor agonist (β2AA) during pregnancy.

Methods: This is a population-based cohort study including all live singleton births in Denmark from 1 January 1997 to 31 December 2008. Children born to mothers who used β2AA during pregnancy were categorized as exposed, and all other children were included in the unexposed group.

Association between polymorphisms of prokineticin receptor (PKR1 rs4627609 and PKR2 rs6053283) and recurrent pregnancy loss.

Recurrent pregnancy loss (RPL) is a condition with complex etiologies, to which both genetic and environmental factors may contribute. During the last decade, studies indicated that the expression patterns of the prokineticin receptor (PKR1 and PKR2) are closely related to early pregnancy. However, there are few studies on the role of PKR1 and PKR2 in RPL.

Couple's infertility in relation to male smoking in a Chinese rural area.

Smoking is a well-known risk factor of reproductive health. However, the effect of paternal smoking on fertility has been less extensively examined. We conducted a cross-sectional study in a mountainous area of South-West China to assess the effect of male smoking on couples' fertility.

Relationship between self-reported residential indoor remodeling and semen quality: a case-control study.

The present study examined the association between residential indoor remodeling and poor semen quality. Sperm donors aged 18-45 years old were recruited in Shanghai, China. Semen specimens were collected and analyzed.

Correlation between exposure to magnetic fields and embryonic development in the first trimester.

Objective: To explore the correlation between maternal magnetic field (MF) exposure in daily life and embryonic development.

Methods: A cross-sectional study was conducted among 149 pregnant women who were seeking induced abortion of unwanted pregnancies. Participating women were asked to wear an EMDEX Lite magnetic field meter for a 24-h period to obtain MF exposure level within 4 weeks following the abortion.

[Feasibility of the aging males' symptoms scale for the male population of Shanghai].

Objective: To assess the reliability and validity of the Aging Males' Symptoms (AMS) scale in the male population of Shanghai.

Methods: We enrolled 973 males aged 40 years and over in a community of Shanghai, China. Using the AMS scale, we calculated the split-half reliability coefficient and Cronbach's alpha coefficient, assessed the validity through confirmatory factor analysis and correlation analysis, and obtained the domain scores of different people by analysis of variance and independent sample test.

Effect of interpregnancy interval after a mifepristone-induced abortion on neonatal outcomes in subsequent pregnancy.

Background: The study evaluated effects of interpregnancy interval (IPI) on neonatal outcomes after mifepristone-induced abortion in the first pregnancy.

Study Design: This observational cohort study, conducted from 1998 to 2001 at antenatal clinics in Shanghai, Beijing, and Chengdu, China, included 4682 nulliparous women with one mifepristone-induced abortion in their first pregnancy, who were enrolled and followed up until delivery. We compared neonatal outcomes among women with different IPIs between their mifepristone-induced abortion and subsequent pregnancy.

Mifepristone-induced abortion and duration of third stage labour in a subsequent pregnancy.

To evaluate the impact of mifepristone-induced abortion (MA) on the duration of third stage labour in a subsequent pregnancy, an observational cohort study was conducted from 1998 to 2001 at antenatal clinics in Shanghai, Beijing and Chengdu, China. A total of 4925 pregnant women with no history of induced abortion (NA) and 4931 pregnant women with one previous MA were enrolled and followed until delivery. Of these, 5139 women who delivered singletons vaginally were used in the present analyses, including 2614 with NA and 2525 with a history of MA.

[A multicenter prospective randomized open comparative study on the treatment of ovulatory menorrhagia with tranexamic acid and norethisterone in China].

Objective: To compare the efficacy and safety of tranexamic acid (TA) and norethisterone (NET) for the treatment of patients with ovulatory menorrhagia in China.

Methods: One hundred and thirty one patients with proven ovulatory menorrhagia from gynecologic clinics of 5 teaching hospitals located in 4 different cities in China were enrolled during Jul 2004 to Dec 2006. Among them 128 completed the study.

[Factors influencing intelligence in elderly population in a community-based study in Taiyuan city].

Objective: To explore the factors which influencing the intelligence in elderly in a community, so as to provide reference on primary prevention of dementia.

Methods: A door to door survey was conducted. A total number of 830 elderly were assessed using WAIS-RC, H-NTLA and data collected through questionnaires on lifestyles, family and social activity were analysed, using the factor analysis, stepwise regression and canonical correlation analysis.
