Although ambient fine particulate matter (PM(2.5); ≤ 2.5 µm in aerodynamic diameter) has been linked to adverse human health effects, the chemical constituents that cause harm are unknown. To our knowledge, effects of PM(2.5) have not reported for a developing country.We examined short-term association between and daily mortality Xi'an, heavily polluted Chinese city.We obtained data concentrations PM(2.5), organic carbon (OC), elemental (EC), 10 water-soluble ions 1 January 2004 through 31...

To investigate the relationship between diabetes and future risk of Parkinson's disease (PD) among older U.S. adults.A prospective study self-reported in 1995 1996 relation to PD diagnosed after 288,662 participants National Institutes Health-AARP Diet Health Study. Multivariate odds ratio (OR) 95% CI were derived from logistic regression models.A total 1,565 with included analysis. After adjustment for potential confounders, was ∼40% higher (OR = 1.41 [95% 1.20-1.66]) diabetic patients than...

OBJECTIVE To examine whether day napping or short night sleeping is associated with higher risk of diabetes. RESEARCH DESIGN AND METHODS This was a prospective study hours and assessed in 1996–1997 relation to diabetes diagnosed between 2000 2006 (n = 10,143) among 174,542 participants the National Institutes Health (NIH)-AARP Diet Study. Odds ratios (ORs) 95% CI were derived from multivariate logistic regression models. RESULTS Longer After adjustment for potential confounders, ORs 1.23...

After heavy metals enter the body, they affect a variety of organs, particularly main metabolic organ, liver. Moreover, people are more likely to be exposed multiple than single metal. We explored associations between exposure metal mixture and liver function biomarkers.This study involved 1171 residents living in areas with or without northeast China. Urine concentrations chromium (Cr), cadmium (Cd), lead (Pb), manganese (Mn) were measured. Total protein (TP), albumin (ALB), aspartate...

Dyslipidemia is a common disease in the older population and represents considerable burden worldwide. Epidemiological experimental studies have indicated associations between heavy metal exposure dyslipidemia; few investigated effects of mixture interactions metals on dyslipidemia. We recruited 1121 participants living metal-contaminated control areas northeast China from cross-sectional survey (2017-2019). Urinary including chromium (Cr), cadmium (Cd), lead (Pb), manganese (Mn)...

Abstract INTRODUCTION Cognitive decline has become a growing public concern, yet large‐scale exposure data identifying the contributing factors remain limited. METHODS We conducted an exposure‐wide association study involving 1142 participants and 207 exposures, using machine learning to assess relative contribution joint effects of key factors. Cluster analysis intervention simulation trials helped identify high‐risk subpopulations potential benefits targeted interventions. RESULTS In...

We conducted a case-control study to examine the association between depression and Parkinson's disease (PD). Participants included 992 PD cases diagnosed after 2,000 279,958 individuals without from NIH-AARP Diet Health Study follow-up survey. Physician-diagnosed were self-reported with information on year of diagnosis in following categories: before 1985, 1985-1994, 1995-1999, 2000-present. Only 2000 analysis. Odds ratios (ORs) 95% confidence intervals (CIs) derived logistic regression...

Adsorption on Na—kaolinite from surfactant mixtures of nonionic octaethylene glycol mono-n-dodecyl ether (C12EO8) with the anionic sodium dodecyl sulfate (C12SO4Na) and cationic dodecyltrimethylammonium chloride [C12(CH3)3NCl was studied in concentration range varying below CMC to above. It found that both systems, adsorption ionic enhanced by presence vice versa pre-CMC region. Chain—chain interaction between adjacent surfactants particles has been proposed be responsible for adsorption....

In recent decades, ambient air pollution has been an important public health issue in Beijing, but little is known about and effects after the 2008 Beijing Olympics. We conduct a time-series analysis to evaluate associations between daily mortality (nonaccidental, cardiovascular respiratory mortality) major pollutants (carbon monoxide, nitrogen dioxide particulate matter less than 10 µm aerodynamic diameter) during two years (2009∼2010) used generalized additive model analyze relationship...

There is a dearth of literature on the incidence dementia in China.Using stratified, multistage, cluster-sampling method, 16,921 nondemented participants ≥55 years were recruited from four regional centers China 1997 and followed up to 4.5 years. Cases identified through three-step protocol, according standardized criteria for dementia, Alzheimer's (AD), vascular (VaD).The crude persons ≥65 was 12.1/1000 person-years 8.2/1000 AD, 3.1/1000 VaD. After adjusting sociodemographic factors, older...
