Health and economic burden of low back pain and rheumatoid arthritis attributable to smoking in 192 countries and territories in 2019.

Background And Aims: Smoking is a risk factor for low back pain (LBP) and rheumatoid arthritis (RA). We aimed to estimate the global health and economic burden of LBP and RA attributable to smoking.

Design: This was a cross-sectional study.

The global health and economic impact of low-back pain attributable to occupational ergonomic factors in the working-age population by age, sex, geography in 2019.

Objective: Occupational ergonomic factors (OEF) include physical exertion, demanding posture, repetitive work, hand-arm vibration, kneeling or squatting, rising, and climbing, which are risk factors for low-back pain (LBP). This study aimed to examine the prevalence, years lived with disability (YLD), healthcare costs, and productivity losses of LBP attributable to OEF by age, sex, World Health Organization region, and country in 2019.

Methods: In this cross-sectional study, prevalence and YLD were extracted from the Global Burden of Diseases, Injuries, and Risk Factors Study 2019.

Analysis of the clinical outcomes of microbial contamination caused by environmental contamination of the embryology laboratory during IVF-ET treatment cycles.

Background: Bacterial contamination may cause loss of or damage to cultured oocytes or embryos, resulting in the lack of transplantable embryos during IVF embryo culture. However, there are few reports about IVF embryo contamination caused by embryology laboratories. In this work, we evaluated clinical pregnancy outcomes and the risk of maternal and infant complications after embryo contamination caused by environmental pollution during IVF.

Health and Economic Outcomes Associated With Musculoskeletal Disorders Attributable to High Body Mass Index in 192 Countries and Territories in 2019.

Importance: The degree to which health and economic outcomes of musculoskeletal disorders are attributable to high body mass index (BMI) has not been quantified on a global scale.

Objective: To estimate global health and economic outcomes associated with musculoskeletal disorders-low back pain (LBP), gout, and osteoarthritis attributable to high BMI in 2019.

Design, Setting, And Participants: This cross-sectional study used data of 192 countries and territories from the Global Burden of Diseases, Injuries, and Risk Factors Study, World Health Organization Global Health Expenditure, World Bank, and International Labour Organization databases.

Trends in Musculoskeletal Rehabilitation Needs in China From 1990 to 2030: A Bayesian Age-Period-Cohort Modeling Study.

Background: Disability and medical expenses caused by musculoskeletal disorders in China had a great impact on the global health and economy. Rehabilitation is essential for dealing with musculoskeletal disorders. However, China's musculoskeletal rehabilitation needs remain unknown.

Secular Trends in Musculoskeletal Rehabilitation Needs in 191 Countries and Territories From 1990 to 2019.

Importance: It is hard for policy makers and health professionals to develop musculoskeletal rehabilitation strategies because secular trends for musculoskeletal rehabilitation by region and country remain unknown.

Objective: To evaluate the secular trends in global musculoskeletal rehabilitation needs by sex, age, region, country, and health condition.

Design, Setting, And Participants: This cross-sectional study included data from 191 countries and territories from the World Health Organization Rehabilitation Need Estimator between January 1, 1990, and December 31, 2019.

Psychometric properties of the traditional Chinese version of the youth attitude to noise scale: a cross-sectional study in a large representative sample.

Objectives: This study aimed to examine the psychometric properties of the traditional Chinese version of the Youth Attitude to Noise Scale (YANS) in a large representative sample.

Design: Cross-sectional study.

Setting: 15 secondary schools in Hong Kong, China.

Association between Non-Restorative Sleep and Quality of Life in Chinese Adolescents.

To examine non-restorative sleep and its impact on quality of life (QOL) in Chinese adolescents, this cross-sectional study included 2827 students aged 12-20 who were selected from 15 secondary schools in Hong Kong, China. Non-restorative sleep was assessed by a single item, rated on a 0-10 scale: "To what extent did you feel refreshed upon awakening over the past month?". QOL was evaluated by the World Health Organization Quality of Life Measure-Abbreviated Version Hong Kong Chinese Version.

Mental health status compared among rural-to-urban migrant, urban and rural school-age children in Guangdong Province, China.

Background: Previous research has documented mental health status among rural-to-urban migrant children (labeled as "migrant children" henceforth) and urban children. However, the findings remain unclear. In addition, far less attention has been paid to rural children's psychological outcomes.

Chronic hypoxia in pregnancy affected vascular tone of renal interlobar arteries in the offspring.

Hypoxia during pregnancy could affect development of fetuses as well as cardiovascular systems in the offspring. This study was the first to demonstrate the influence and related mechanisms of prenatal hypoxia (PH) on renal interlobar arteries (RIA) in the 5-month-old male rat offspring. Following chronic hypoxia during pregnancy, phenylephrine induced significantly higher pressor responses and greater vasoconstrictions in the offspring.

Hippocampal apoptosis involved in learning deficits in the offspring exposed to maternal high sucrose diets.

The hippocampus plays a crucial role in learning and memory, and neuronal apoptosis in the hippocampus contributes to learning deficits. Metabolism problems in pregnancy related to excessive fuel consumption (e.g.

Prenatal exposure to hypoxia induced Beclin 1 signaling-mediated renal autophagy and altered renal development in rat fetuses.

Aims: Hypoxia has adverse effects on renal development. This study was the first to test hypoxia-induced renal autophagy in rat fetuses.

Methods: Pregnant rats were exposed to hypoxia or normoxia during pregnancy and fetal kidneys were collected at gestation day 21.

High-salt diets during pregnancy affected fetal and offspring renal renin-angiotensin system.

Intrauterine environments are related to fetal renal development and postnatal health. Influence of salty diets during pregnancy on renal functions and renin-angiotensin system (RAS) was determined in the ovine fetuses and offspring. Pregnant ewes were fed high-salt diet (HSD) or normal-salt diet (NSD) for 2 months during middle-to-late gestation.

Angiotensin II-mediated vascular changes in aged offspring rats exposed to perinatal nicotine.

This study determined the long-term influence of prenatal nicotine exposure (PN) on blood pressure and vascular functions in the aged offspring rats. PN did not affect body weight and plasma adrenocorticotropic hormone level; however, it significantly reduced plasma angiotensin I and angiotensin II in both sexes. Systolic pressure in the male aged PN offspring was significantly higher.
