Obesity is associated with several metabolic and endocrine disorders; and changes in plasma concentrations, secretion patterns, and clearance of various hormones are observed in obese patients. In this context, recent research has shown that overweight can influence the function of the thyroid gland, usually leading to increased thyrotropin concentrations and changes in the ratio between the hormones triiodothyronine and thyroxine, though within the normal range. The etiology of these changes is still unclear; however, several mechanisms have been proposed including the adaptive process to increase energy expenditure, hyperleptinemia, changes in the activity of deiodinases, the presence of thyroid hormones resistance, chronic low-grade inflammation, and insulin resistance...

OBJECTIVES: Growing evidence indicates that ambient (AAP: NO2 , PM2.5 and O3 ) and traffic-related air pollutants (TRAP) contribute to metabolic disease risk in adults; however, few studies have examined these relationships in children. METHODS: Metabolic profiling was performed in 429 overweight and obese African-American and Latino youth living in urban Los Angeles, California. This cross-sectional study estimated individual residential air pollution exposure and used linear regression to examine relationships between air pollution and metabolic outcomes...

BACKGROUND: Advanced cancer treatments have improved survival from cancer, but the incidence of cardiovascular disease in survivors has recently increased. Sarcopenia and metabolic syndrome (MetS) are related to cancer survival, and sarcopenia is an emerging risk factor for cardiovascular disease. However, evidence of a relationship between sarcopenia and MetS in cancer survivors is lacking. OBJECTIVES: The aims of this study were to determine the prevalence of sarcopenia and MetS in cancer survivors and to investigate independent predictors of MetS in cancer survivors...

PURPOSE: Regional cerebral perfusion is coupled to metabolism in general. Early perfusion dominant imaging using F-FP-CIT PET (pCIT) may provide complementary information to delayed dopamine transporter dominant images. We investigated the ability of pCIT to differentiate atypical Parkinson disorder from Parkinson disease (PD) compared to FDG and the image quality for optimizing the acquisition time. METHODS: Sixty-seven subjects [PD, 23 subjects; multiple system atrophy-cerebellar type (MSA-C), 27 subjects; MSA-Parkinson type (MSA-P), 12 subjects; and progressive supranuclear palsy (PSP), 5 subjects] underwent F-FP-CIT and FDG PET...

PURPOSE OF REVIEW: Metabolic myopathies are genetic disorders that impair intermediary metabolism in skeletal muscle. Impairments in glycolysis/glycogenolysis (glycogen-storage disease), fatty acid transport and oxidation (fatty acid oxidation defects), and the mitochondrial respiratory chain (mitochondrial myopathies) represent the majority of known defects. The purpose of this review is to develop a diagnostic and treatment algorithm for the metabolic myopathies. RECENT FINDINGS: The metabolic myopathies can present in the neonatal and infant period as part of more systemic involvement with hypotonia, hypoglycemia, and encephalopathy; however, most cases present in childhood or in adulthood with exercise intolerance (often with rhabdomyolysis) and weakness...

PURPOSE OF REVIEW: This article discusses the clinical features, pathophysiology, and management of toxic and endocrine myopathies. RECENT FINDINGS: Early detection and expeditious correction of metabolic disturbances in endocrinopathies such as Cushing syndrome, thyroid and parathyroid diseases, and acromegaly can minimize and prevent neurologic complications including myopathy. Recently proposed mechanisms of injury in patients with critical illness myopathy include inhibition of protein synthesis, mitochondrial dysfunction, disruption of the ubiquitin-proteasome system, oxidative stress, and disruption of intramuscular calcium homeostasis, which can cause a myosin-loss myopathy...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) can be considered the hepatic manifestation of the metabolic syndrome with nonalcoholic steatohepatitis (NASH) as its progressive form. With increasing prevalence of the metabolic syndrome, NASH cirrhosis is becoming a leading cause for liver transplantation. Some cases of orthotopic liver transplantation (OLT) due to cryptogenic cirrhosis (CC) might show typical features of NASH cirrhosis. Therefore, our aim was to assess recurrence of liver fibrosis in patients transplanted for NASH versus CC after OLT...

Reverse transcription quantitative-polymerase chain reaction (RT-qPCR) is a routine method for gene expression analysis, and reliable results depend on proper normalization by stable reference genes. Caloric restriction (CR) is a robust lifestyle intervention to slow aging and delay onset of age-associated diseases via inducing global changes in gene expression. Reliable normalization of RT-qPCR data becomes crucial in CR studies. In this study, the expression stability of 12 candidate reference genes were evaluated in inguinal white adipose tissue (iWAT), skeletal muscle (Sk...

Obesity is associated with a number of metabolic disorders that lead to the development of type 2 diabetes, hyperlipidemia and ultimately cardiovascular diseases. An important role in the pathogenesis of metabolic disorders accompanying obesity is probably played by the alterations of adipose tissue characteristics: metabolic, endocrine and immune functions. The key component of obesity treatment, the weight-reduction energy-restricted diet, leads not only to the reduction of weight (specifically fat mass), but also to correction of obesity accompanying metabolic disorders...

The present generation of women of childbearing age more frequently suffer from overweight, obesity, initial as well as fully established metabolic syndrome, which together with postponing motherhood until the third decade in life plays an important role in the increasing incidence of gestational diabetes (GDM) that currently affects about 1/5 of pregnant women. However the causal link between diabetes during pregnancy and metabolic diseases in the whole population is mutual. By way of epigenetic changes, maternal diabetes unfavourably programmes metabolism of the offspring, who tend to transfer the disorder to the next generations...

The term metabolic syndrome (MeS) refers to a cluster of associated symptoms composed of impaired fasting glucose, abdominal obesity, hypertension, and dyslipidemia. MeS is associated with an increased risk of cardiovascular and diabetes-associated morbidity and mortality. The increased amount of visceral fat together with a chronic inflammatory state predisposes to the development of arteriosclerosis. Furthermore, insulin resistance (IR) and dyslipidemia are associated with fatty liver disease. In addition, MeS is linked to non-cardiovascular diseases such as cancer as well as psychiatric or endocrine disorders...

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease throughout the world. Pathophysiological insights into this disease have recently illustrated that various factors such as insulin resistance, innate immunity, metabolic inflammation, and the microbiota are of relevance. NAFLD, metabolic syndrome (MS), and type 2 diabetes (T2D) share many pathophysiological aspects, and inflammatory processes in the adipose tissue, gut, and liver have evolved to be of exceptional importance. Most of NAFLD patients are obese and encounter a high risk of developing MS and T2D...
