Sex specificity in associations between exposure to a mixture of per and poly-fluoroalkyl substances and anxiety among US adults.

Background: Exposure to per and poly-fluoroalkyl substances (PFAS) is suggested to interfere with the central nervous system that may affect mental health. Studies on the relationships between exposure to PFAS mixtures and anxiety in humans are rare. This study aimed to evaluate the associations between single and combined exposure to PFAS and anxiety among adults.

Short-term effect of ambient temperature change on the risk of tuberculosis admissions: Assessments of two exposure metrics.

Background: Although the effects of seasonal variations and ambient temperature on the incidence of tuberculosis (TB) have been well documented, it is still unknown whether ambient temperature change is an independent risk factor for TB. The aim of this study was to assess the association between ambient temperature change and the risk of TB admissions.

Method: A distributed lag non-linear model (DLNM) combined with Poisson generalized linear regression model was performed to assess the association between ambient temperature change and the risk of TB admissions from 2014 to 2018 in Hefei, China.

Association between short-term exposure to ambient air pollutants and the risk of tuberculosis outpatient visits: A time-series study in Hefei, China.

Background: The current evidence has presented mixed results between air pollutants exposure and the progression of tuberculosis (TB). The purpose of this study was to explore the association between short-term exposure to air pollutants and the risk of TB outpatient visits in Hefei, China.

Methods: Time-series analysis was used to assess the effect of short-term exposure to ambient air pollutants on the risk of TB outpatient visits.

Elevated parathyroid hormone levels and cognitive function: A systematic review.

Objective: To systematically estimate the association between elevated parathyroid hormone (PTH) levels and cognitive function.

Methods: This review was conducted on ten papers identified through database searches from inception to 31 October 2018. The quality of studies was assessed using the Downs and Black checklist.

Risk factors for spontaneous abortion from a prevention perspective in rural China: a population-based follow-up study.

Objectives: We conducted this study to investigate the risk factors for spontaneous abortion among rural Chinese women.

Methods: Risk factors prior to pregnancy associated with spontaneous abortion were identified among 17,248 rural women enrolled in a prospective population-based follow-up study. The risk of spontaneous abortion was estimated with odds ratio (OR) and 95% confidence interval (CI) for several factors.

Associations of telomere length in risk and recurrence of prostate cancer: A meta-analysis.

Over the past decades, there is an increasing number of association studies of telomere length (TL) and the risk and recurrence of prostate cancer (PCa), but the results are inconsistent. Hence, we identify the relevant studies published in English on or before 10 January 2019 conducting a literature review in the electronic databases including PubMed, EMBASE and Cochrane Library. Twelve studies (with 19 data sets) were included in this meta-analysis, five of which were associated with risk assessment, six of which reported recurrence of PCa and one of which included them.

Large for gestational age and macrosomia in pregnancies without gestational diabetes mellitus.

This study aims to estimate the prevalence and risk factors of macrosomia and LGA (large for gestational age) in non-GDM (gestational diabetes mellitus) pregnant women in Fuyang, Anhui Province of China. A large population-based cohort study was conducted among non-GDM pregnant women aged 18-45 years. Maternal sociodemographic data prior to pregnancy were collected using interviewer-administered standardized questionnaire.

Association between ambient air pollution and Parkinson's disease: Systematic review and meta-analysis.

Air pollution has been evaluated as a possible risk factor for Parkinson's disease (PD), but, the present results are inconsistent and have not been combined. We performed a systematic review and meta-analysis to estimate the association between long-term exposure to ambient air pollution and PD, given the nature of disease etiology. A total of 10 studies were identified by searching Web of Science, Science Direct, and PubMed before October 2017.

Association between sleep duration and high blood pressure in adolescents: a systematic review and meta-analysis.

Context: Sleep has been assessed as a risk factor for health consequences. Among adults, excessively longer and shorter sleep durations are associated with high blood pressure (BP), but knowledge of the association between sleep duration and high BP among adolescents is limited.

Objectives: To estimate the associations between sleep duration and high BP in adolescents.

Associations between hypospadias, cryptorchidism and anogenital distance: Systematic review and meta-analysis.

Hypospadias and cryptorchidism are potential manifestations of testicular dysgenesis syndrome (TDS) at birth. Anogenital distance (AGD) has been presumed as an indicator related to endocrine disruptors proposed as one of the pathogenetic mechanisms underlying male reproductive disorders. In humans, recent studies have correlated AGD in boys to testicular anomalies.

The prevalence and risk factors of menstrual pain of married women in Anhui Province, China.

Purpose: To investigate the prevalence and the associated risk factors for menstrual pain in a sample of rural married women of reproductive age in Anhui Province of China.

Methods: A cross-sectional study was conducted among married women (n = 14,828) aged 18-45 years. Data were collected through self-reported questionnaires.

Pre-Pregnancy Health Status and Risk of Preterm Birth: A Large, Chinese, Rural, Population-Based Study.

The aim of this study was to estimate the incidence of preterm birth (PTB) and identify maternal risk factors before pregnancy in rural China, and to determine their population-attributable fractions (PAFs). A prospectively population-based study was conducted in the city of Fuyang, China. Surveillance locations were randomly selected by cluster sampling based on administrative areas and geographic characteristics.

The association between prenatal bisphenol A exposure and birth weight: a meta-analysis.

The association between prenatal BPA exposure and birth weight is controversial. Here, a meta-analysis was performed to estimate the association between prenatal BPA exposure and birth weight. We searched literature addressing the association of interest in relevant databases.

Longitudinal trajectory of vulvovaginal candidiasis, trichomoniasis, and bacterial vaginosis during pregnancy as well as the impact on pregnancy outcomes: a preliminary study.

The aims of this study were to describe the course of vulvovaginal candidiasis (VVC), trichomoniasis, and bacterial vaginosis (BV) in pregnancy and to explore the association between these longitudinal changes and pregnancy outcomes. A total of 793 pregnant women were enrolled at the first trimester of pregnancy and were followed prospectively twice at the second and third trimester. VVC, trichomoniasis, and BV were evaluated at each trimester of pregnancy.
