BACKGROUND: Epidemiological studies have shown the associations of ambient temperature and particulate matter (PM) air pollution with respiratory morbidity and mortality. However, the underlying mechanisms have not been well characterized. The aim of this study is to investigate the associations of temperature and fine and coarse PM with fractional exhaled nitric oxide (FeNO), a well-established biomarker of respiratory inflammation. METHODS: We conducted a longitudinal panel study involving six repeated FeNO tests among 33 type 2 diabetes mellitus patients from April to June 2013 in Shanghai, China...

BACKGROUND: In Taiwan, Changhua County residents were exposed to high heavy metal pollution and exhibited high heavy metal levels in blood and urine. We examined associations between heavy metals in residential soil and renal outcomes of residents with chronic kidney disease (CKD). METHOD: From January 01, 2003 to June 30, 2015, we retrospectively identified CKD patients with an estimated glomerular filtration rate of <60 mL/min/1.73 m(2) at one tertiary care center...

Cardiovascular disease (CVD) is the leading cause of death in Hispanic Americans. Social and physical determinants of health unique to this community must be understood before interventions can be designed and implemented. This article describes a CVD risk assessment conducted in a primarily Mexican American community, using Healthy People 2020 as a model. Social (language, culture, awareness of CVD, and socio-economic status) and physical (presence and use of recreation areas, presence of grocery stores, public transportation, and environmental pollution) determinants of health as well as access to health services were assessed...

Oxidative states exert a significant influence on a wide range of biological and molecular processes and functions. When their balance is shifted towards enhanced amounts of free radicals, pathological phenomena can occur, as the generation of reactive oxygen species (ROS) in tissue microenvironment or in the systemic circulation can be detrimental. Epidemic chronic diseases of western societies, such as cardiovascular disease, obesity, and diabetes correlate with the imbalance of redox homeostasis. Current advances in our understanding of epigenetics have revealed a parallel scenario showing the influence of oxidative stress as a major regulator of epigenetic gene regulation via modification of DNA methylation, histones, and microRNAs...

Previous in vivo and in vitro studies have linked perfluorinated compound (PFC) exposure with metabolic interruption, but the inter-species difference and high treatment doses usually make the results difficult to be extrapolated to humans directly. The best strategy for identifying the metabolic interruption may be to establish the direct correlations between monitored PFCs data and metabolic data on human samples. In this study, serum metabolome data and PFC concentrations were acquired for a Chinese adult male cohort...

Ozone, one of the most important air pollutants, is a triatomic molecule containing three atoms of oxygen that results in an unstable form due to its mesomeric structure. It has been well-known that ozone has potent ability to oxidize organic compounds and can induce respiratory irritation. Although ozone has deleterious effects, many therapeutic effects have also been suggested. Since last decades, the therapeutic potential of ozone has gained much attention through its strong capacity to induce controlled and moderated oxidative stress when administered in precise therapeutic doses...

Obesity and associated metabolic disorders represent a major societal challenge in health and quality of life with large psychological consequences in addition to physical disabilities. They are also one of the leading causes of morbidity and mortality. Although, different etiologic factors including excessive food intake and reduced physical activity have been well identified, they cannot explain the kinetics of epidemic evolution of obesity and diabetes with prevalence rates reaching pandemic proportions...

Exposure to small particulate matter (PM2.5) has become the 5th highest ranking risk factor for death, responsible for 4.2 million deaths worldwide. PM pollution is also associated with cardiovascular disease and type 2 diabetes, and may contribute to deteriorate the already poor cardiometabolic outlook of the diabetic patient. Although most sources of outdoor air pollution are well beyond the control of individuals, there is still room for personal action. Health behaviors (smoking cessation, avoiding obesity, and increasing physical activity) may increase the poor life expectancy of individuals in the lowest income quartile of the Western population; moreover, a favorable lifestyle, (no current smoking, no obesity, physical activity at least once weekly, and a healthy diet pattern), may cut by nearly 50% the risk of coronary heart disease among people at high genetic risk...

INTRODUCTION: Cardio-metabolic risk factors including insulin levels are at young age barely perceived as harmful, but over time these risk factors may track and lead to higher risk of metabolic syndrome. Studies showed that exposure to air pollution is associated with an increased risk of insulin resistance in childhood. We determined whether the origin of type 2 diabetes can be found in the early childhood by examining the levels of insulin in the neonatal cord blood and whether this can be considered as a disease marker for later life...

Previous studies have demonstrated that exposure to the pulmonary irritant ozone causes myriad systemic metabolic and pulmonary effects attributed to sympathetic and hypothalamus-pituitary-adrenal (HPA) axis activation, which are exacerbated in metabolically-impaired models. We examined respiratory and systemic effects following exposure to a sensory irritant acrolein to elucidate the systemic and pulmonary consequences in healthy and diabetic rat models. Male Wistar and Goto Kakizaki (GK) rats, a non-obese type II diabetic Wistar-derived model, were exposed by inhalation to 0, 2, or 4 ppm acrolein, 4h/day for 1 or 2 days...

G V Krishnaveni, C S Yajnik
The developmental origins of health disease (DOHaD) hypothesis proposes that altered environmental influences (nutrition, metabolism, pollutants, stress and so on) during critical stages of fetal growth predisposes individuals to diabetes and other non-communicable disease in later life. This phenomenon is thought to reflect permanent effects ('programming') of unbalanced fetal development on physiological systems. Intrauterine programming may underlie the characteristic Indian 'thin-fat' phenotype and the current unprecedented epidemic of diabetes on the backdrop of multigenerational maternal undernutrition in the country...

Nutrients that regulate methylation processes may modify susceptibility to the effects of air pollutants. Data from the National Birth Defects Prevention Study, 1997-2006, were used to estimate associations between maternal exposure to nitrogen dioxide (NO2), dietary intake of methyl nutrients and the odds of congenital heart defects in offspring. NO2 concentrations, a marker of traffic-related air pollution, averaged across post-conception weeks 2-8, were assigned to 6160 non-diabetic mothers of cases and controls using inverse distance-squared weighting of air monitors within 50 km of maternal residence...

Diabetics may be more vulnerable to the harmful effects of ambient air pollutants than healthy individuals. But, the risk factors that lead to susceptibility to air pollution in diabetics have not yet been identified. We examined the effect of exposure to ambient PM10 on chronic symptoms and the pulmonary function tests (PFT) in diabetic and non-diabetic subjects. Also, to investigate possible determinants of susceptibility, we recruited 400 type 2 diabetic and 465 healthy subjects who were investigated for chronic respiratory symptoms (CRSs) and then underwent measurement of forced vital capacity (FVC) and forced expiratory volume 1 (FEV1) according to standard protocol...

The environmental obesogen model proposes that in addition to a high-calorie diet and diminished physical activity, other factors such as environmental pollutants and chemicals are involved in the development of obesity. Although arsenic has been recognized as a risk factor for Type 2 Diabetes with a specific mechanism, it is still uncertain whether arsenic is also an obesogen. The impairment of white adipose tissue (WAT) metabolism is crucial in the onset of obesity, and distinct studies have evaluated the effects of arsenic on it, however only in some of them for obesity-related purposes...

Identifying communities vulnerable to adverse health effects from exposure to wildfire smoke may help prepare responses, increase the resilience to smoke and improve public health outcomes during smoke days. We developed a Community Health-Vulnerability Index (CHVI) based on factors known to increase the risks of health effects from air pollution and wildfire smoke exposures. These factors included county prevalence rates for asthma in children and adults, chronic obstructive pulmonary disease, hypertension, diabetes, obesity, percent of population 65 years of age and older, and indicators of socioeconomic status including poverty, education, income and unemployment...

BACKGROUND: First Nations (FNs) populations in Canada experience a disproportionally higher rate of obesity and type 2 diabetes (T2D) compared to the general population. Recent data suggest that a high consumption of fish may help prevent T2D. On the other hand, fish might also be a potential source of environmental contaminants which could potentially be a risk factor for T2D. OBJECTIVE: To investigate the potential associations between self-reported T2D and consumption of locally-harvested fish, dietary long-chain omega-3 fatty acids (n-3FAs) and persistent organic pollutants intake among adult FNs living on reserve in Ontario...

Recent studies have shown an association between air pollution and diabetic risk. This study was to investigate the impact of fine particulate matter (PM2.5) on glucose consequences and pancreas glucose transporter 2 (GLUT2) expression and its related mechanisms in a gestational diabetes mellitus (GDM) rat model. GDM rats were exposed to a low PM2.5 dose while the controls received saline. Interleukin-6 (IL-6) and blood routine tests (BRT) were detected for analyzing coagulation and inflammation. Pancreas tissues underwent pathologic examination, the levels of homogenate glutathione peroxidase (GSH-Px), and methane dicarboxylic aldehyde (MDA) were detected for oxidative stress estimation, and the degree of GLUT2 expression of pancreas was analyzed...

BACKGROUND: Air pollution has been a serious public health threat worldwide. It has been linked to pulmonary and cardiovascular diseases but is also believed to contribute to air-pollution-mediated cardiometabolic disease such as diabetes. We investigated the relationship between type 2 diabetes mellitus (DM2) and air pollution in densely developed urban settings in South Korea, using national epidemiologic data. METHODS: The analysis focused on examining gender-related differences in the relationship between DM 2 and air pollutants, specifically particulate matter ≤ 10μm (PM10) and sulfur dioxide (SO2)...
