Aluminium levels in hair and urine are associated with overweight and obesity in a non-occupationally exposed population

The objective of the present study was to investigate the association between hair and urine Al levels and obesity.MethodsA total of 206 lean and 205 obese non-occupationally exposed subjects (30-50 y.o.) were enrolled in the study. Hair and urine Al levels were assessed with ICP-MS. Laboratory quality control was performed using the certified reference materials of human hair, plasma, and urine.ResultsHair and urinary Al levels in obese subjects were significantly higher by 31% and 46% compared to the control levels, respectively. The presence of hypertension (41% cases), atherosclerosis (8%), type 2 diabetes mellitus (10%), and non-alcoholic fatty liver disease (NAFLD) (53%) in obese patients were not associated with Al levels in the studied subjects. An overall multiple regression model established urinary Al levels (β = 0.395; p

Non-alcoholic fatty liver disease (NAFLD) is a growing challenge to global public health. It is defined as the increased accumulation of hepatic triglyceride (>5%) in the absence of excessive alcohol consumption or other causes of liver disease. The NAFLD spectrum encompasses steatosis (non-alcoholic fatty liver, NAFL) and non-alcoholic steatohepatitis (NASH), an inflammatory form of the condition marked by the presence of hepatocyte damage and progressive fibrosis that may lead to cirrhosis.[1,2] Although NAFLD may occur in patients with normal weight, it is closely associated with the presence of the metabolic syndrom...

Conclusions: Bariatric surgery appears to be capable of partially reversing the obesity-related epigenome. The identification of potential epigenetic biomarkers predictive for the success of bariatric surgery may open new doors to personalized therapy for severe obesity. Introduction Obesity is currently a huge healthcare problem, worldwide, and is a risk factor for several diseases such as type 2 diabetes (T2D), cardiovascular disease and cancer (1). As the prevalence of obesity reaches pandemic proportions, this metabolic disease is estimated to become the biggest cause of mortality in the near future (2). In fact,...

Conclusions: Our study shows that a higher burden of liver steatosis seems to be associated with less severe stroke and better functional outcome after ischemic stroke or TIA. Introduction Non-alcoholic fatty liver disease (NAFLD) is a spectrum of diseases from simple steatosis to steatohepatitis with varying degree of fibrosis, and liver cirrhosis (1, 2). NAFLD is becoming the most common chronic liver disease worldwide including Korea, affecting approximately 25% of the general population (3, 4). NAFLD is closely associated with obesity, insulin resistance, and type 2 diabetes mellitus, and is even recognized as ...

Authors: Dwyer AA, Quinton R Abstract The metabolic syndrome (MetS) is a term used to describe the constellation of cardiometabolic risk factors including central adiposity, dyslipidemia, insulin resistance, non-alcoholic fatty liver disease and arterial hypertension. Notably, a number of studies have shown high rates of testosterone (T) deficiency in men with MetS and type 2 diabetes mellitus (T2DM). Both hypogonadism and MetS confer increased health risk for morbidity and mortality as men with the MetS are at twice the risk for developing cardiovascular disease and at 5-fold higher risk for developing T2DM. Moreo...

Authors: Gierej P, Gierej B, Kalinowski P, Wróblewski T, Paluszkiewicz R, Kobryń K, Ziarkiewicz-Wróblewska B Abstract Adipokines are cytokines that presumably connect the pathologies of metabolic syndrome. One of the adipokines is resistin, the role of which in insulin resistance, obesity, and non-alcoholic fatty liver disease (NAFLD) needs to be determined. Liver biopsy specimens were obtained intraoperatively from 214 obese patients. Histological assessment was based on NAFLD activity score according to Kleiner. Statistical analysis involved semi-quantitive immunohistochemistry assessment of resist...

Abstract Metabolic syndrome (MetS) is a cluster of central obesity, dyslipidaemia, insulin resistance and hypertension. MetS frequently co-exists with non-alcoholic fatty liver disease (NAFLD), which is characterized by fat accumulation in the liver in the absence of alcohol abuse, viral hepatitis and other causes of chronic liver diseases. Both MetS and NAFLD are associated with an increased risk for cardiovascular disease and type 2 diabetes mellitus. There are also other associations between MetS and NAFLD. In the present narrative review, we discuss the links between MetS and NAFLD in terms of prevalence, risk...

Abstract Lipoprotein (a) [Lp(a)] is an independent but moderate, predictor for coronary heart disease (CHD) prevalence and severity. Several established and emerging cardiovascular (CV) risk factors including age, gender, ethnicity, smoking, dyslipidemia, hypertension, obesity, type 2 diabetes mellitus, alcohol consumption, arterial stiffness and hyperuricemia have been linked to Lp(a) metabolism. Apart from CHD, Lp(a) has been also associated with non-cardiac vascular diseases and diseases associated with increased CV risk such as chronic kidney disease, metabolic syndrome, non-alcoholic fatty liver disease, erec...

However, the causal relationship between UA and these different clinical problems is still debatable. The recent years have witnessed hundreds of experimental and clinical trials that favored the opinion that UA is a probable player in the pathoge...

Abstract After the first description of fatty pancreas in 1933, the effects of pancreatic steatosis have been poorly investigated, compared with that of the liver. However, the interest of research is increasing. Fat accumulation, associated with obesity and the metabolic syndrome (MetS), has been defined as "fatty infiltration" or "nonalcoholic fatty pancreas disease" (NAFPD). The term "fatty replacement" describes a distinct phenomenon characterized by death of acinar cells and replacement by adipose tissue. Risk factors for developing NAFPD include obesity, increasing age, male sex...

Metabolic syndrome and type 2 diabetes mellitus constitute a major problem to global health, and their incidence is increasing at an alarming rate. Non-alcoholic fatty liver disease, which affects up to 90% of obese people and nearly 70% of the overweight, is commonly associated with MetS characteristics such as obesity, insulin resistance, hypertension and dyslipidemia. In the present study, we demonstrate that hepatic lipase (HL)-inactivation in mice fed with a high-fat, high-cholesterol diet produced dyslipidemia including hypercholesterolemia, hypertriglyceridemia and increased non-esterified fatty acid levels. These c...
