    Rett syndrome (RTT) requires total caregiver attention and leads to potential difficulties throughout life. The Caregiver Burden Inventory, designed for Alzheimer disease, was modified to a RTT Caregiver Inventory Assessment (RTT CIA). Reliability and face, construct, and concurrent validity were assessed in caregivers of individuals with RTT. Chi square or Fisher's exact test for categorical variables and t tests or Wilcoxon two-sample tests for continuous variables were utilized. Survey completed by 198 caregivers; 70 caregivers completed follow-up assessment. Exploratory factor analysis revealed good agreement for physical burden, emotional burden, and social burden. Internal reliability was high (Cronbach's alpha 0.898). RTT CIA represents a reliable and valid measure, providing a needed metric of caregiver burden in this disorder.

    Metabolic syndrome (Mets) is a combination of disorders including abdominal obesity, impaired glucose tolerance, dyslipidemia and hypertension, which increases risk for cardiovascular disease (CVD) and type 2 diabetes when occurring together. In Japan, diagnosis criteria of Mets consists of an increased waist circumference and 2 or more of CVD risk factors. Annual health checkups and health guidance using Mets criteria were established in 2008 for the prevention of life-style related diseases in Japan. In this issue, history and diagnostic criteria of Mets and concerns for Mets concept were described.

    The United States is experiencing its greatest life expectancy ever. Nonetheless, the general health of the US population is far from at an all-time high. An important contributor to the pandemic of cardiovascular disease is that overweight and obesity are also the major determinants of metabolic syndrome, an all too common and all too serious clinical and public health challenge. Clinicians have traditionally evaluated each of the major risk factors contributing to metabolic syndrome on an individual basis. There is evidence, however, that the risk factors are more than additive. The overlap of these factors in each disease state, resulting in increased atherogenic risks, is worth examining as a broader entity rather than separately. While therapeutic lifestyle changes (TLCs) should be strongly recommended, clinicians should not let the perfect be the enemy of the possible. Evidence-based doses of statins, aspirin and angiotensin-converting enzyme inhibitors, or angiotensin II receptor blockers should be prescribed as adjuncts, not alternatives, to TLCs. In fact, there is cogent evidence that the benefits of these pharmacologic therapies may also be at least additive.

    The incidence of cardiovascular disease increases considerably after the menopause. One reason for the increased cardiovascular risk seems to be determined by metabolic syndrome, in which all components (visceral obesity, dyslipidemia, hypertension, and glucose metabolism disorder) are associated with higher incidence of coronary artery disease. After menopause, metabolic syndrome is more prevalent than in premenopausal women, and may plays an important role in the occurrence of myocardial infarction and other atherosclerotic and cardiovascular morbidities. Obesity, an essential component of the metabolic syndrome, is also associated with increased incidence of breast, endometrial, bowel, esophagus, and kidney cancer. The treatment of metabolic syndrome is based on the change in lifestyle and, when necessary, the use of medication directed to its components. In the presence of symptoms of the climacteric syndrome, hormonal therapy, when indicated, will also contribute to the improvement of the metabolic syndrome.

    The metabolic syndrome is a cluster of easy-to-measure clinical phenotypes that serve as markers for increased risk for CVD and diabetes. There is no universal agreement as to the underlying pathophysiology of the metabolic syndrome. At its core, the metabolic syndrome is the result of energy excess; therefore treating obesity is a good strategy to reverse the clinical features of the metabolic syndrome. Hypertension is a special case, may not be part of the core pathophysiology of the metabolic syndrome, and will not be discussed. After a brief review of recent developments in the pathophysiology of the metabolic syndrome, this review will concentrate on peripheral targets in the following categories: ectopic fat and fat oxidation, intrinsic defects in substrate switching and mitochondrial biogenesis, lipolysis and lipid turnover, adipose tissue as an endocrine organ, nutrient / energy sensing systems, and inflammation. The advantages and pitfalls of these targets will be discussed with an eye towards the relevant literature.

    The prevalence of metabolic syndrome has paralleled the sharp increase in obesity. Given its tremendous physical, emotional, and financial burden, it is of critical importance to identify who is most at risk and the potential points of intervention. Psychological traits, in addition to physiological and social risk factors, may contribute to metabolic syndrome. The objective of the present research is to test whether personality traits are associated with metabolic syndrome in a large community sample. Participants (N = 5,662) from Sardinia, Italy, completed a comprehensive personality questionnaire, the NEO-PI-R, and were assessed on all components of metabolic syndrome (waist circumference, triglycerides, high-density lipoprotein cholesterol, blood pressure, and fasting glucose). Logistic regressions were used to predict metabolic syndrome from personality traits, controlling for age, sex, education, and current smoking status. Among adults over age 45 (n = 2,419), Neuroticism and low Agreeableness were associated with metabolic syndrome, whereas high Conscientiousness was protective. Individuals who scored in the top 10% on Conscientiousness were approximately 40% less likely to have metabolic syndrome (OR = 0.61, 95% CI = 0.41–0.92), whereas those who scored in the lowest 10% on Agreeableness were 50% more likely to have it (OR = 1.53, 95% CI = 1.09–2.16). At the facet level, traits related to impulsivity and hostility were the most strongly associated with metabolic syndrome. The present research indicates that those with fewer psychological resources are more vulnerable to metabolic syndrome and suggests a psychological component to other established risk factors.

    The metabolic syndrome is a multiplex risk factor for atherosclerotic cardiovascular disease and type 2 diabetes. It is composed of atherogenic dyslipidemia, elevated blood pressure, insulin resistance and elevated glucose, a pro-thrombotic state, and a pro-inflammatory state. Excess energy intake and concomitant obesity are the major drivers of the syndrome. Lifestyle intervention can reverse metabolic risk factors, but at times, drug therapies or bariatric surgery may be required to control more overt risk factors. Published by Elsevier Inc.

    The Japanese Orthopedic Association coined the term locomotive syndrome (LS) to designate a condition of elderly people in high risk groups of requiring nursing care because of problems with their musculoskeletal diseases. LS is a socioeconomic concept, and closely associated with osteoporosis, osteoarthritis, and sarcopenia. Recent studies have revealed that metabolic syndrome (MS), a clustering of cardiovascular risk factors, has been related with LS. For example, individuals with MS have a greater risk of osteoarthritis and sarcopenia. Secreted factors from adipose tissue and skeletal muscles, namely, adipokines and myokines, are involved in the association of LS and MS.

    Polycystic ovary syndrome (PCOS) is a heterogeneous condition characterized by androgen excess, ovulatory dysfunction, and polycystic ovaries. It is the most common endocrinopathy among women of reproductive age, affecting between 6.5% and 8% of women, and is the most common cause of infertility. Insulin resistance is almost always present in women with PCOS, regardless of weight, and they often develop diabetes and metabolic syndrome. The Rotterdam criteria are widely used for diagnosis. These criteria require that patients have at least two of the following conditions: hyperandrogenism, ovulatory dysfunction, and polycystic ovaries. The diagnosis of PCOS also requires exclusion of other potential etiologies of hyperandrogenism and ovulatory dysfunction. The approach to PCOS management differs according to the presenting symptoms and treatment goals, particularly the patient's desire for pregnancy. Weight loss through dietary modifications and exercise is recommended for patients with PCOS who are overweight. Oral contraceptives are the first-line treatment for regulating menstrual cycles and reducing manifestations of hyperandrogenism, such as acne and hirsutism. Clomiphene is the first-line drug for management of anovulatory infertility. Metformin is recommended for metabolic abnormalities such as prediabetes, and a statin should be prescribed for cardioprotection if the patient meets standard criteria for statin therapy.

    That obesity in the USA has reached epidemic proportions is undeniable: one in three American adults is obese. High levels of obesity yield adverse microeconomic and macroeconomic effects, but assessing the viability of bariatric surgery in this respect requires careful consideration of its efficacy, its economic costs, and the benefits of the surgery. Metabolic syndrome is a microcosm of multiple disease states; the diseases that fall under the umbrella of the metabolic syndrome are, like obesity, becoming more prevalent. Epidemic obesity in part reflects inadequate utilization of bariatric surgery and inadequate coordination of efforts by the healthcare system. An integrated delivery network (IDN) is the best current model to achieve healthcare goals for patient subsets that are deemed important. Our overweight population, both with and without the metabolic syndrome, constitutes such a group because of the fraction of the general population they compose, the inherent costs to the healthcare system that their comorbid conditions generate, and the lost productivity to our economy that the treatment of these conditions entail. In this paper, we show a metabolic syndrome service line that will benefit both the individual hospital and the healthcare system. Pathways accepted for bariatric practices can be used, with modification, for the creation of a metabolic syndrome IDN. Implementation of such a system would benefit patients, caregivers, and society.

    Chronic persistent inflammation plays a significant role in disease pathology of cancer, cardiovascular disease, and metabolic syndrome (MetS). MetS is a constellation of diseases that include obesity, diabetes, hypertension, dyslipidemia, hypertriglyceridemia, and hypercholesterolemia. Nonalcoholic fatty liver disease (NAFLD) is associated with many of the MetS diseases. These metabolic derangements trigger a persistent inflammatory cascade, which includes production of lipid autacoids (eicosanoids) that recruit immune cells to the site of injury and subsequent expression of cytokines and chemokines that amplify the inflammatory response. In acute inflammation, the transcellular synthesis of antiinflammatory eicosanoids resolve inflammation, while persistent activation of the autacoid-cytokine-chemokine cascade in metabolic disease leads to chronic inflammation and accompanying tissue pathology. Many drugs targeting the eicosanoid pathways have been shown to be effective in the treatment of MetS, suggesting a common linkage between inflammation, MetS and drug metabolism.The cross-talk between inflammation and MetS seems apparent because of the growing evidence linking immune cell activation and metabolic disorders such as insulin resistance, dyslipidemia, and hypertriglyceridemia. Thus modulation of lipid metabolism through either dietary adjustment or selective drugs may become a new paradigm in the treatment of metabolic disorders. This review focuses on the mechanisms linking eicosanoid metabolism to persistent inflammation and altered lipid and carbohydrate metabolism in MetS. PMID:23433458

    Metabolic syndrome is associated with abdominal obesity, blood lipid disorders, inflammation, insulin resistance or full-blown diabetes, and increased risk of developing cardiovascular disease. Proposed criteria for identifying patients with metabolic syndrome have contributed greatly to preventive medicine, but the value of metabolic syndrome as a scientific concept remains controversial. The presence of metabolic syndrome alone cannot predict global cardiovascular disease risk. But abdominal obesity - the most prevalent manifestation of metabolic syndrome - is a marker of 'dysfunctional adipose tissue', and is of central importance in clinical diagnosis. Better risk assessment algorithms are needed to quantify diabetes and cardiovascular disease risk on a global scale.

    Metabolic syndrome (MS) is characterized by the following symptoms: obesity, AH, dyslipidemia, insulin resistance. Pathophysiologically, MS is underlain by disorders of many biochemical and physiological processes, such as elevated levels of low density lipoproteins, hyperstimulation of pancreatic b-cells, increased insulin secretion, substitution of lipid metabolism for carbohydrate one, overgrowth of adipose tissue, excess production of adiponectin, leptin and other signal molecules and a rise in their local intravascular concentration, weight gain. Endogenous and exogenous melatonin inhibits these pathophysiological mechanisms, normalizes metabolism, equilibrates insulin secretion, prevents pancreatic hyperfunction, phosphorylates insulin receptors, inactivates active oxygen and nitrogen species including those produced in LDLP metabolism. Melatonin has specific MT1 and MT2 receptors localized in all body cells. Due to this, it exerts combined preventive action in patients with MS. Recently, melatonin has been reported to have therapeutic effect in MS; it may be recommended to treat this condition.

    The role of gut bacteria in the pathogenesis and treatment of various diseases has been a focus of attention in the last 10 years. Prevalence of diabetes, obesity, and cardiovascular diseases continues to increase, in spite of technological developments and treatment alternatives. Microbial dysbiosis, described as the decrease of useful bacteria and the increase of harmful bacteria, has been associated with diabetes, obesity, atherosclerosis, and metabolic syndrome. In microbial dysbiosis, increase of harmful metabolites and changes to composition of bile acids occur via carbohydrate and protein fermentation. As a result, insulin resistance pathways are activated, which initiate the processes of obesity, diabetes, and atherosclerosis. Healthy diet recommendations, including prebiotic and probiotic foods and the use of probiotic agents, look promising for future treatment of metabolic syndrome and cardiovascular diseases.

    Metabolic syndrome is a fast growing public health burden for almost all the developed countries and many developing nations. Despite intense efforts from both biomedical and clinical scientists, many fundamental questions regarding its aetiology and development remain unclear, partly due to the lack of suitable imaging technologies to visualize lipid composition and distribution, insulin secretion, β-cell mass and functions in vivo. Such technologies would not only impact on our understanding of the complexity of metabolic disorders such as obesity and diabetes, but also aid in their diagnosis, drug development and assessment of treatment efficacy. In this article we discuss and propose several strategies for visualization of physiological and pathological changes that affect pancreas and adipose tissue as a result of the development of metabolic diseases.

    Obesity is one of the constellation of factors that make up the definition of the metabolic syndrome. Metabolic syndrome is also associated with insulin resistance, dyslipidemia, hypertriglyceridemia, and type 2 diabetes mellitus. The presence of obesity and metabolic syndrome in men and women is also associated with increased risk of cardiovascular disease and hypertension. In men, obesity and metabolic syndrome are associated with reductions in testosterone levels. In women, obesity and metabolic syndrome are associated with increases in androgen levels. In men, reductions in androgen levels are associated with inflammation, and androgen supplements reduce inflammation. In women, increases in androgens are associated with increases in inflammatory cytokines, and reducing androgens reduces inflammation. This review discusses the possibility that the effects of androgens on metabolic syndrome and its sequelae may differ between males and females.

    The aim of our study was to investigate the influence of metabolic syndrome on the course of acute pancreatitis determined by disease severity, the presence of local and systemic complications and survival rate. 609 patients admitted to our hospital in the period from January 1, 2008 up to June 31, 2015 with the diagnosis of acute pancreatitis were analyzed. The diagnosis and the severity of acute pancreatitis were made according to the revised Atlanta classification criteria from 2012. Of 609 patients with acute pancreatitis, 110 fulfilled the criteria for metabolic syndrome. Patients with metabolic syndrome had statistically significantly higher incidence of moderately severe (38.2% vs. 28.5%; p=0.05) and severe (22.7% vs. 12.8%; p=0.01) acute pancreatitis in comparison to those without metabolic syndrome, while patients without metabolic syndrome had higher incidence of mild acute pancreatitis in comparison to those patients with metabolic syndrome (58.7% vs. 39.1%; p<0.001). Patients with metabolic syndrome had a higher number of local and systemic complications, and higher APACHE II score in comparison to patients without metabolic syndrome. In multivariable logistic regression analysis, the presence of metabolic syndrome was independently associated with moderately severe and severe acute pancreatitis. Comparing survival rates, patients suffering from metabolic syndrome had a higher death rate compared to patients without metabolic syndrome (16% vs. 4.5%; p<0.001). The presence of metabolic syndrome at admission portends a higher risk of moderately severe and severe acute pancreatitis, as well as higher mortality rate.

    The metabolic syndrome (MetSy) is increasingly common in Australia. It is associated with the rise in obesity and lifestyle risk behaviours. It is also controversial - its value in predicting cardiovascular disease and diabetes risk and in guiding therapy has been challenged. This article aims to provide advice on the diagnosis of the MetSy and the principles for its prevention and management in the context of primary care, taking into consideration aetiological factors and the complexity of managing its constituent risk factors. Diagnosis of the MetSy is useful in focusing attention on central adiposity and insulin resistance as risk factors both for the syndrome, and cardiovascular and diabetes morbidity and mortality. Its assessment requires measurement of waist circumference - a simple but seldom performed procedure in general practice. The most essential components for the prevention and management of the MetSy are measures to change diet and physical activity in order to achieve and sustain weight loss.

    The gut microbiome contributes approximately 2kg of the whole body weight, and recent studies suggest that gut microbiota has a profound effect on human metabolism, potentially contributing to several features of the metabolic syndrome. Metabolic syndrome is defined by a clustering of metabolic disorders that include central adiposity with visceral fat accumulation, dyslipidemia, insulin resistance, dysglycemia and non-optimal blood pressure levels. Metabolic syndrome is associated with an increased risk of cardiovascular diseases and type 2 diabetes. It is estimated that around 20-25 percent of the world's adult population has metabolic syndrome. In this manuscript, we have reviewed the existing data linking gut microbiome with metabolic syndrome. Existing evidence from studies both in animals and humans support a link between gut microbiome and various components of metabolic syndrome. Possible pathways include involvement with energy homeostasis and metabolic processes, modulation of inflammatory signaling pathways, interferences with the immune system, and interference with the renin-angiotensin system. Modification of gut microbiota via prebiotics, probiotics or other dietary interventions has provided evidence to support a possible beneficial effect of interventions targeting gut microbiota modulation to treat components or complications of metabolic syndrome.

    Metabolic syndrome (MetS) is a cluster of metabolic traits associated with an increased risk of cardiovascular disease and type 2 diabetes mellitus. Central obesity and insulin resistance are thought to play key roles in the pathogenesis of the MetS. The MetS has a significant genetic component, and therefore linkage analysis, candidate gene approach, and genome-wide association (GWA) studies have been applied in the search of gene variants for the MetS. A few variants have been identified, located mostly in or near genes regulating lipid metabolism. GWA studies for the individual components of the MetS have reported several loci having pleiotropic effects on multiple MetS-related traits. Genetic studies have provided so far only limited evidence for a common genetic background of the MetS. Epigenetic factors (DNA methylation and histone modification) are likely to play important roles in the pathogenesis of the MetS, and they might mediate the effects of environmental exposures on the risk of the MetS. Further research is needed to clarify the role of genetic variation and epigenetic mechanisms in the development of the MetS.

    A vast majority of menopausal women suffer from vasomotor symptoms, such as hot flushes and night sweats, the mean duration of which may be up to 7-10 years. In addition to a decreased quality of life, vasomotor symptoms may have an impact on overall health. Vasomotor symptoms are associated with overactivity of the sympathetic nervous system, and sympathetic overdrive in turn is associated with metabolic syndrome, which is a known risk factor for cardiovascular disease. Menopausal hot flushes have a complex relationship to different features of the metabolic syndrome and not all data point towards an association between vasomotor symptoms and metabolic syndrome. Thus, it is still unclear whether vasomotor symptoms are an independent risk factor for metabolic syndrome. Research in this area is constantly evolving and we present here the most recent data on the possible association between menopausal vasomotor symptoms and the metabolic syndrome.

    Metabolic syndrome and hypovitaminosis D are 2 diseases with high prevalence that share several risk factors, while epidemiological evidence shows they are associated. Although the mechanisms involved in this association are not well established, hypovitaminosis D is associated with insulin resistance, decreased insulin secretion and activation of the renin-angiotensin system, mechanisms involved in the pathophysiology of metabolic syndrome. However, the apparent ineffectiveness of vitamin D supplementation on metabolic syndrome components, as well as the limited information about the effect of improving metabolic syndrome components on vitamin D concentrations, does not clarify the direction and the mechanisms involved in the causal relationship between these 2 pathologies. Overall, because of the high prevalence and the epidemiological association between both diseases, hypovitaminosis D could be considered a component of the metabolic syndrome.

    The clustering of cardiovascular risk factors such as abdominal obesity, hypertension, dyslipidaemia and glucose intolerance in the same persons has been called the metabolic or insulin-resistance syndrome. In 1998 WHO proposed a unifying definition for the syndrome and chose to call it the metabolic syndrome rather than the insulin-resistance syndrome. Although insulin resistance has been considered as a common denominator for the different components of the syndrome, there is still debate as to whether it is pathogenically involved in all of the different components of the syndrome. Clustering of the syndrome in families suggests a genetic component. It is plausible that so-called thrifty genes, which have ensured optimal storage of energy during periods of fasting, could contribute to the phenotype of the metabolic syndrome. Common variants in a number of candidate genes influencing fat and glucose metabolism can probably, together with environmental triggers, increase susceptibility to the syndrome. Among these, the genes for beta 3-adrenergic receptor, hormone-sensitive lipase, lipoprotein lipase, IRS-1, PC-1, skeletal muscle glycogen synthase, etc. appear to increase the risk of the metabolic syndrome. In addition, novel genes may be identified by genome-wide searches.

    Polycystic ovary syndrome (PCOS) is a heterogeneous disorder, where the main clinical features include menstrual irregularities, sub-fertility, hyperandrogenism, and hirsutism. The prevalence of PCOS depends on ethnicity, environmental and genetic factors, as well as the criteria used to define it. On the other hand, metabolic syndrome is a constellation of metabolic disorders which include mainly abdominal obesity, insulin resistance, impaired glucose metabolism, hypertension and dyslipidaemia. These associated disorders directly increase the risk of Type 2 diabetes mellitus (DMT2), coronary heart disease (CHD), cardiovascular diseases (CVD) and endometrial cancer. Many patients with PCOS have features of metabolic syndrome such as visceral obesity, hyperinsulinaemia and insulin resistance. These place patients with PCOS under high risk of developing cardiovascular disease (CVD), Type 2 diabetes (DMT2) and gynecological cancer, in particular, endometrial cancer. Metabolic syndrome is also increased in infertile women with PCOS. The aim of this review is to provide clear and up to date information about PCOS and its relationship with metabolic syndrome, and the possible interaction between different metabolic disorders.

    The task of improving patient and caregiver satisfaction in the management of myelodysplastic syndromes (MDS) poses many challenges for physicians and patient care teams. Advances in the understanding of MDS biology have resulted in the approval of 3 agents for the treatment of MDS by the US Food and Drug Administration (FDA) in the past decade. However, according to a retrospective physician survey, the majority of recently diagnosed patients with MDS still receive supportive care only. Interestingly, a survey performed in patients with MDS suggests that patient understanding of treatment goals and prognosis is often limited, with a third of patients reporting that prognosis was not discussed with their physician. Efforts to improve patient awareness of their disease severity and establishing clear treatment goals are crucial for setting up an individualized treatment plan and ensuring optimal patient and caregiver satisfaction.

    Metabolic syndrome is characterized by a combination of various cardiovascular risk factors (age, gender, smoking, hypertension and dyslipidemia) that imply additional cardiovascular morbidity that is greater than the sum of the risks associated with each individual component. Herein, the authors review the rheumatological diseases in which metabolic syndrome has been studied: gout, osteoarthritis, systemic lupus erythematosus, rheumatoid arthritis, Sjögren's syndrome and ankylosing spondylitis. The prevalence of metabolic syndrome in these disorders varies from 14% to 62.8%. The great majority of these studies demonstrated that this frequency was higher in rheumatological diseases than in the control populations, suggesting that either the presence or the treatment of those diseases seems to influence the risk of developing metabolic syndrome.

    Metabolic syndrome is becoming a worldwide medical and public health challenge as it has been seen increasing in prevalence over the years. Age-related eye diseases, the leading cause of blindness globally and visual impairment in developed countries, are also on the rise due to aging of the population. Many of the individual components of the metabolic syndrome have been shown to be associated with these eye diseases. However, the association of metabolic syndrome with eye diseases is not clear. In this review, we reviewed the evidence for associations between metabolic syndrome and certain ocular diseases in populations. We also reviewed the association of individual metabolic syndrome components with ocular diseases due to a paucity of research in this area. Besides, we also summarised the current understanding of etiological mechanisms of how metabolic syndrome or the individual components lead to these ocular diseases. With increasing evidence of such associations, it may be important to identify patients who are at risk of developing metabolic syndrome as prompt treatment and intervention may potentially decrease the risk of developing certain ocular diseases.

    The metabolic syndrome is a cluster of risk factors associated with an increased risk for cardiovascular disease and type 2 diabetes. Based on data from 1988 to 1994, it is estimated that 24% of adults in the United States meet the criteria for diagnosis of the metabolic syndrome. The use of certain medications may increase the risk of the metabolic syndrome by either promoting weight gain or altering lipid or glucose metabolism. Health providers should recognize and understand the risk associated with certain medications and appropriately monitor for changes related to the metabolic syndrome. Careful attention to drug choices should be paid in patients who are overweight or have other risk factors for diabetes or cardiovascular disease.

    Drug abuse is associated with significant health risk. Whether drug abusers are at a higher risk of suffering the metabolic syndrome is not widely known. The metabolic syndrome is a cluster of metabolic abnormalities, including hyperinsulinemia, hypertension, dyslipidemia, and abdominal obesity, and is probably triggered by initial imbalances at the cellular level in various critical metabolic pathways. These initially small metabolic imbalances are believed to cascade with time and lead to larger problems. Some indications that drug abuse may increase the risk of the metabolic syndrome include the following: Drug-abusing patients have higher rates of diabetes complications. Substance abuse is a significant contributing factor for treatment noncompliance in diabetes. Nutrition education can enhance substance abuse treatment outcomes. Each type of drug/substance abuse has a unique profile of toxicity. For example, the amphetamines generally affect the cardiovascular and neurological systems, worsening the risk factors for the metabolic syndrome. Methamphetamine (meth) abusers suffer cognitive deficits and abnormal metabolic activity, which affect nutritional status. This condition is further worsened by a drastic reduction in oral health in meth abusers, resulting in improper chewing and, therefore, digestion. Nutritional deficiency in combination with drug abuse would increase the risk of developing the metabolic syndrome by increasing cell damage, augmenting excitotoxicity, reducing energy production, and lowering the antioxidant potential of the cells. Another potential risk factor in the development of the metabolic syndrome is genetic vulnerability, especially in combination with drug abuse and nutritional deficiencies. The strategies available to treat this problem include pharmacological agents as well as dietary antioxidants. Such measures may be useful in reducing drug abuse-related toxicity that may lead to the metabolic syndrome.

    Interest in the metabolic syndrome-associated osteoarthritis phenotype is increasing. Here, we summarize recently published significant findings. Meta-analyses confirmed an association between type 2 diabetes and osteoarthritis and between cardiovascular diseases and osteoarthritis. Recent advances in the study of metabolic syndrome-associated osteoarthritis have focused on a better understanding of the role of metabolic diseases in inducing or aggravating joint damage. In-vivo models of obesity, diabetes, or dyslipidemia have helped to better decipher this association. They give emerging evidence that, beyond the role of common pathogenic mechanisms for metabolic diseases and osteoarthritis (i.e., low-grade inflammation and oxidative stress), metabolic diseases have a direct systemic effect on joints. In addition to the impact of weight, obesity-associated inflammation is associated with osteoarthritis severity and may modulate osteoarthritis progression in mouse models. As well, osteoarthritis synovium from type 2 diabetic patients shows insulin-resistant features, which may participate in joint catabolism. Finally, exciting data are emerging on the association of gut microbiota and circadian rhythm and metabolic syndrome-associated osteoarthritis. The systemic role of metabolic syndrome in osteoarthritis pathophysiology is now better understood, but new avenues of research are being pursued to better decipher the metabolic syndrome-associated osteoarthritis phenotype.

    Laminitis is one of the most common and frustrating clinical presentations in equine practice. While the principles of treatment for laminitis have not changed for several decades, there have been some important paradigm shifts in our understanding of laminitis. Most importantly, it is essential to consider laminitis as a clinical sign of disease and not as a disease in its own right. Once this shift in thinking has occurred, it is logical to then question what disease caused the laminitis. More than 90 per cent of horses presented with laminitis as their primary clinical sign will have developed it as a consequence of endocrine disease; most commonly equine metabolic syndrome (EMS). Given the fact that many horses will have painful protracted and/or chronic recurrent disease, a good understanding of the predisposing factors and how to diagnose and manage them is crucial. Current evidence suggests that early diagnosis and effective management of EMS should be a key aim for practising veterinary surgeons to prevent the devastating consequences of laminitis. This review will focus on EMS, its diagnosis and management.

    Polycystic ovary syndrome (PCOS) is associated with a range of metabolic complications including insulin resistance (IR), obesity, dyslipidaemia, hypertension, obstructive sleep apnoea (OSA) and non-alcoholic fatty liver disease. These compound risks result in a high prevalence of metabolic syndrome and possibly increased cardiovascular (CV) disease. As the cardiometabolic risk of PCOS is shared amongst the different diagnostic systems, all women with PCOS should undergo metabolic surveillance though the precise approach differs between guidelines. Lifestyle interventions consisting of increased physical activity and caloric restriction have been shown to improve both metabolic and reproductive outcomes. Pharmacotherapy and bariatric surgery may be considered in resistant metabolic disease. Issues requiring further research include the natural history of PCOS-associated metabolic disease, absolute CV risk and comparative efficacy of lifestyle interventions.

    The inflammatory component of atherogenesis has been increasingly recognized over the last decade. Inflammation participates in all stages of atherosclerosis, not only during initiation and during evolution of lesions, but also with precipitation of acute thrombotic complications. The metabolic syndrome is associated with increased risk for development of both cardiovascular disease and type-2 diabetes in humans. Central obesity and insulin resistance are thought to represent common underlying factors of the syndrome, which features a chronic low-grade inflammatory state. Diagnosis of the metabolic syndrome occurs using defined threshold values for waist circumference, blood pressure, fasting glucose and dyslipidemia. The metabolic syndrome appears to affect a significant proportion of the population. Therapeutic approaches that reduce the levels of proinflammatory biomarkers and address traditional risk factors are particularly important in preventing cardiovascular disease and, potentially, diabetes. The primary management of metabolic syndrome involves healthy lifestyle promotion through moderate calorie restriction, moderate increase in physical activity and change in dietary composition. Treatment of individual components aims to control atherogenic dyslipidemia using fibrates and statins, elevated blood pressure, and hyperglycemia. While no single treatment for the metabolic syndrome as a whole yet exists, emerging therapies offer potential as future therapeutic approaches. PMID:17319458

    Butyrylcholinesterase may have a role in a number of metabolic functions and could affect the expression of insulin resistance syndrome. We present our integrated work using clinical, biochemical and bioinformatic approaches to delineate the possible function of this enzyme. Initially, we constructed a phylogenic tree with nucleotides and amino acid sequences and showed the existence of similar sequences in bacteria, plants and in other animals. We also demonstrated a possible pathogenic role for BChE in the common existence of insulin resistance, type 2 diabetes and Alzheimer's disease by in silico method and followed it up with a diabetic mouse study where cognition was slowed along with changes in BChE levels. In the next group of in silico studies, we employed THEMATICS method to identify the amino acids at the active site and later performed docking studies with drugs. THEMATICS predicted two clusters of ionisable amino acid residues that are in proximity: one with two residues and another with 11 showed perturbation in the THEMATICS curves. Using ISIS/Draw 2.5SP4, ARGUSLAB 4.0.1 and HEX 5.1. software. 3-D ligands were docked with BChE motif (from PDB). We did not find any of the ligands studied with significant docking distance, indicating they did not have direct interaction with the active site. Subsequently we performed in silico studies to compare the secondary structure and domain of BChE. Protein-protein interaction showed the following intersections with BChE UBE21, CHAT, APOE, AATF, DF ALDH9A1, PDHX, PONI PSME3 and ATP6VOA2. The integrative physiological roles of proteins with poorly known functions can be approached by generating leads in silico, which can be studied in vivo, setting into movement an iterative process.

    Controversies surround the usefulness of identifying patients with the metabolic syndrome (MetS). Many of the components are accepted risk factors for cardiovascular disease (CVD). Although the MetS as defined includes many men with insulin resistance, insulin resistance is not universal. The low total testosterone (TT) and sex hormone binding globulin (SHBG) levels in these men are best explained by the hyperinsulinism and increased inflammatory cytokines that accompany obesity and increased waist circumference. It is informative that low SHBG levels predict future development of the MetS. Evidence is strong relating low TT levels to CVD in men with and without the MetS; however, the relationship may not be causal. The recommendations of the International Diabetes Federation for managing the MetS include cardiovascular risk assessment, lifestyle changes in diet, exercise, weight reduction and treatment of individual components of the MetS. Unfortunately, it is uncommon to see patients with the MetS lose and maintain a 10% weight loss. Recent reports showing testosterone treatment induced dramatic changes in weight, waist circumference, insulin sensitivity, hemoglobin A1c levels and improvements in each of the components of the MetS are intriguing. While some observational studies have reported that testosterone replacement therapy increases cardiovascular events, the Food and Drug Administration in the United States has reviewed these reports and found them to be seriously flawed. Large, randomized, placebo-controlled trials are needed to provide more definitive data regarding the efficacy and safety of this treatment in middle and older men with the MetS and low TT levels.

    To review the data with respect to prevalence of metabolic syndrome (MetS) and its correlates in schizophrenia. For this review, electronic search engines PUBMED, Sciencedirect, and Google Scholar were used. Available data suggests that most of the studies have been of cross-sectional design. Prevalence rates of MetS have varied from 11% to 69% in medicated patients, and 4-26% in drug naive patients in cross-sectional evaluations. Longitudinal studies have shown the prevalence rates to range from 0% to 14% at the baseline in drug naive patients, which increase to as high as 52.4% by 3 months of antipsychotic medication treatment. The prevalence rates of MetS in patients with schizophrenia are much higher than that seen in general population or healthy controls. Though there is no causal association with any demographic or clinical variables, the risk increases with increase in age. Among antipsychotics, there seems to be an association between MetS and atypical antipsychotics like clozapine and olanzapine. Therefore, the psychiatrists should be more vigilant regarding the presence of MetS in these high risk groups. Research on biological correlates of MetS in schizophrenia is still in its primitive stage, however, these is some evidence to suggest an association of MetS with adiponectin levels, hematological indices, methylenetetrahydrofolate reductase (MTHFR) and Alpha-1A adrenergic receptor (ADRA1A) gene. These areas hold promise, and targeting these with appropriate interventions may help us to prevent the occurrence of MetS in patients with schizophrenia in future. PMID:24249923

    Androgenic alopecia has been associated with an increased risk of coronary heart disease in various studies. The relationship between androgenic alopecia and metabolic syndrome, a known risk factor for atherosclerotic cardiovascular disease, is still poorly understood. To study the association between metabolic syndrome and early-onset androgenic alopecia. A hospital-based analytical cross-sectional study was done on men in the age group of 18-55 years. Eighty five clinically diagnosed cases with early-onset (<35 years) androgenic alopecia of Norwood grade III or above, and 85 controls without androgenic alopecia were included. Data collected included anthropometric measurements, arterial blood pressure and history of chronic diseases. Fasting blood and lipid profile were determined. Metabolic syndrome was diagnosed as per the new International Diabetes Federation criteria. Chi-square and Student's t-test were used for statistical analysis using Statistical Package for the Social Sciences (SPSS) version 17.00. Metabolic syndrome was seen in 19 (22.4%) patients with androgenic alopecia and 8 (9.4%) controls (P = 0.021). Abdominal obesity, hypertension and lowered high-density lipoprotein were significantly higher in patients with androgenic alopecia versus their respective controls. The limitations of our study include small sample size in subgroups and the lack of evidence of a temporal relationship between metabolic syndrome and androgenic alopecia. A higher prevalence of metabolic syndrome is seen in men with early-onset androgenic alopecia. Early screening for metabolic syndrome and its components is beneficial in patients with early-onset androgenic alopecia.

    The fibric acid derivative, fenofibrate (FF) has been used in the US since 1998 to manage patients with dyslipidemia. Typical changes in serum lipids as a result of FF treatment include clinically important mean reductions of serum triglycerides (TG) by a mean change of −93.7 mg/dL (−39.3%), increases of high density lipoprotein cholesterol (HDLC) by +5.5 mg/dL (+12.4%), and reductions in low density lipoprotein cholesterol (LDLC) by −17.9 mg/dL (−12.3%). The greatest reductions in serum TG are usually observed in subjects with elevated baseline TG including those with the metabolic syndrome (MetS). Although statins remain the mainstay of therapy for most dyslipidemic patients, their combined use with FF would be expected to address residual risk resulting from less than optimal TG and HDLC levels in such patients. Clinical trials examining the cardiovascular benefits of FF alone or combined with statins have produced mixed results. These observations underscore our lack of understanding of which patients may benefit from FF therapy and which do not. Although FF’s basic mechanism of action is known to involve PPAR-α agonist activity resulting in altered transcription of several genes, the actual genetic bases for variability in lipid response is poorly understood. Studies, such as our GOLDN study and others were designed to better understand the genetic determinants of variability in the response to FF treatment and lipid levels. As a result several important genetic determinants of lipid levels have been identified. For example, in the GOLDN study SNPs from different genes were significantly associated with baseline lipid levels before treatment (APOA5-rs662799, rs3135506; APOC3-rs5128, rs2854117, rs4520); APOA4-rs5104; PPARA-rs9626730, rs135543, rs11703495; LPL-rs1801177), after treatment PPARA-rs11708495; LPL-rs1801177, and appeared to modulate overall response to FF treatment (NOS3-rs1799983).

    This article explores the surprising finding that bariatric surgery can produce full and durable remission of the metabolic syndrome as well as other comorbidities of obesity including type II diabetes, hypertension, polycystic ovary syndrome, gastroesophageal reflux disease, nonalcoholic steatotic hepatitis, adult asthma and improvement in weight-bearing arthropathy. Such an outcome was previously deemed impossible. One effect of the surgery is the correction of hyperinsulinemia, a common denominator in the various expressions of the metabolic syndrome. Basal insulin levels return to normal levels within a matter of days following surgery, allowing a return of the first phase of insulin secretion. This effect is 'dose related' to the extent of the reduction of contact between food and the gut. The resolution of the spectrum of diseases that comprise the metabolic syndrome following bariatric surgery suggests that hyperinsulinemia may be the common cause that is corrected by lowering contact between food and the gut. If this concept is true, then the cause of the syndrome, including diabetes, could be a diabetogenic signal from the gut that forces the islets to produce excessive and harmful levels of insulin, or the cause could be the removal of a signal that blocks excessive insulin secretion. If either of these mechanisms is proven correct, the current treatment of diabetes with long-term insulin administration deserves review.

    Metabolic syndrome is a compilation of symptoms including central obesity, insulin resistance, dyslipidemia, and hypertension. Initially used to predict cardiovascular disease, it is now clear that the molecular and physiologic abnormalities seen in metabolic syndrome extend well beyond the cardiovascular system. Growing evidence has linked metabolic syndrome and its individual symptoms to the increasing prevalence of male infertility. This manuscript reviews the recent evidence connecting metabolic syndrome to male infertility as well as the underlying pathophysiology. Currently, there are limited prospective studies examining the effects of treating metabolic syndrome on male reproduction and these relationships will need to be a focus of further investigation.

    Study Objectives: In this study, we investigated the prevalence of symptoms of restless legs syndrome (RLS) in biological caregivers of children with a diagnosis of autism spectrum disorder (ASD).The relationship of RLS symptoms to caregiver health-related quality of life (HRQoL) was also examined. Finally, we compared the sleep quality and daytime behaviors of children with ASD in caregivers with and without symptoms of RLS. Methods: Biological caregivers (n = 50) of children ages 6 to 11 y with a diagnosis of ASD completed a Sleep Habits Questionnaire (SHQ) that included RLS as determined by four questions. HRQoL was assessed using the Medical Outcomes Survey (MOS) 12-Item Short Form (SF-12). Caregivers also completed the Children's Sleep Habits Questionnaire (CSHQ) and Child Behavior Checklist (CBCL6/18). Results: Eleven caregivers (22%) fit the criteria for RLS symptomatology and caregivers with RLS reported poorer mental health. Caregivers with RLS described more night waking and greater internalized behavior problems in their children with ASD than the caregivers without RLS. Conclusions: Biological caregivers of children with ASD demonstrated a high prevalence of RLS symptoms and poorer mental health. RLS is known as a sleep disorder that has strong heritability, and it is possible that many of the children with ASD also have symptoms of RLS. RLS as a possible disruptor of sleep should be considered in caregivers and in their children with ASD. Citation: Russell M, Baldwin C, McClain D, Matthews N, Smith C, Quan SF.

  15. Phytoestrogens and the metabolic syndrome.

    PubMed

    Jungbauer, Alois; Medjakovic, Svjetlana

    2014-01-01

    Phytoestrogens are a diverse class of non-steroidal compounds that have an affinity for estrogen receptors α and β, for the peroxisome proliferator-activated receptor (PPAR) family and for the aryl hydrocarbon receptor. Examples of phytoestrogens include prenylated flavonoids, isoflavones, coumestans and lignans. Many phytoestrogens counteract the cellular derailments that are responsible for the development of metabolic syndrome. Here we propose a mechanism of action which is based on five pillars/principles. First, phytoestrogens are involved in the downregulation of pro-inflammatory cytokines, such as COX-2 and iNOS, by activating PPAR and by inhibiting IκB activation. Second, they increase reverse cholesterol transport, which is mediated by PPARγ. Third, phytoestrogens increase insulin sensitivity, which is mediated via PPARα. Fourth, they exert antioxidant effects by activating antioxidant genes through KEAP. Fifth, phytoestrogens increase energy expenditure by affecting AMP-activated kinase signaling cascades, which are responsible for the inhibition of adipogenesis. In addition to these effects, which have been demonstrated in vivo and in clinical trials, other effects, such as eNOS activation, may also be important. Some plant extracts from soy, red clover or licorice can be described as panPPAR activators. Fetal programming for metabolic syndrome has been hypothesized; thus, the consumption of dietary phytoestrogens during pregnancy may be relevant. Extracts from soy, red clover or licorice oil have potential as plant-derived medicines that could be used to treat polycystic ovary syndrome, a disease linked to hyperandrogenism and obesity, although clinical trials have not yet been conducted. Phytoestrogens may help prevent metabolic syndrome, although intervention studies will be always be ambiguous, because physical activity and reduced calorie consumption also have a significant impact. Nevertheless, extracts rich in phytoestrogens may be an

Although metabolic syndrome may not necessarily cause cancer, it is linked to poorer cancer outcomes including increased risk of recurrence and overall mortality. This review tends to discuss the major biological and physiological alterations involved in the increase of incidence and mortality of cancer patients affected by metabolic syndrome. We focus on metabolic syndrome-associated visceral adiposity, hyperinsulinemia, hyperglycemia, insulin-like growth factor (IGF-I) pathway as well as estrogen signaling and inflammation. Several of these factors are also involved in carcinogenesis and cancer progression. A better understanding of the link between metabolic syndrome and cancer may provide new insight about oncogenesis. Moreover, prevention of metabolic syndrome - related alterations may be an important aspect in the management of cancer patients during simultaneous palliative care.

    2012-03-01

    Metabolic syndrome is commonly accompanied by an elevated cardiovascular risk with high morbidity and mortality. The alterations of the arterial vasculature begin with endothelial dysfunction and lead to micro- and macrovascular complications. The remodeling of the endothelial basal membrane, that promotes erosion and thrombosis, has a multifactorial pathogenesis that includes leukocyte activation, increased oxidative stress and also an altered matrix metalloproteinases (MMPs) expression. MMPs are endopeptidases which degrade extracellular matrix proteins, such as collagen, gelatins, fibronectin and laminin. They can be secreted by several cells within the vascular wall, but macrophages are determinant in the atherosclerotic plaques. Their activity is regulated by tissue inhibitors of MMP (TIMPs) and also by other molecules, such as plasmin. MMPs could be implicated in plaque instability predisposing to vascular complications. It has been demonstrated that an impaired MMP or TIMP expression is associated with higher risk of all-cause mortality. A large number of studies evaluated MMPs pattern in obesity, diabetes mellitus, arterial hypertension and dyslipidemia, all of which define metabolic syndrome according to several Consensus Statement (i.e. IDF, ATP III, AHA). However, few research have been carried out on subjects with metabolic syndrome. The evidences of an improvement in MMP/TIMP ratio with diet, exercise and medical therapy should encourage further investigations with the intent to contrast the atherosclerotic process and to reduce morbidity and mortality of this kind of patients.

    Metabolic syndrome defines a cluster of interrelated risk factors for cardiovascular disease and diabetes mellitus. These factors include metabolic abnormalities, such as hyperglycemia, elevated triglyceride levels, low high-density lipoprotein cholesterol levels, high blood pressure, and obesity, mainly central adiposity. In this context, extracellular vesicles (EVs) may represent novel effectors that might help to elucidate disease-specific pathways in metabolic disease. Indeed, EVs (a terminology that encompasses microparticles, exosomes, and apoptotic bodies) are emerging as a novel mean of cell-to-cell communication in physiology and pathology because they represent a new way to convey fundamental information between cells. These microstructures contain proteins, lipids, and genetic information able to modify the phenotype and function of the target cells. EVs carry specific markers of the cell of origin that make possible monitoring their fluctuations in the circulation as potential biomarkers inasmuch their circulating levels are increased in metabolic syndrome patients. Because of the mixed components of EVs, the content or the number of EVs derived from distinct cells of origin, the mode of cell stimulation, and the ensuing mechanisms for their production, it is difficult to attribute specific functions as drivers or biomarkers of diseases. This review reports recent data of EVs from different origins, including endothelial, smooth muscle cells, macrophages, hepatocytes, adipocytes, skeletal muscle, and finally, those from microbiota as bioeffectors of message, leading to metabolic syndrome. Depicting the complexity of the mechanisms involved in their functions reinforce the hypothesis that EVs are valid biomarkers, and they represent targets that can be harnessed for innovative therapeutic approaches. © 2017 American Heart Association, Inc.

    Metabolic syndrome has become a major public health problem worldwide and represents a common clinical condition in countries with a high incidence of obesity and western dietary patterns. Metabolic syndrome associates with common cancers at many sites, including liver, colorectal, and bladder cancers in men, and endometrial, pancreatic, breast post-menopausal, and colorectal cancers in women. However, the role played by each single component of the syndrome on cancer risk is still unclear. For endometrial cancer, obesity and/or high circumference waist explain all the risk associated with the full metabolic syndrome, while for post-menopausal breast cancer, the risk conveyed by metabolic syndrome appears to be greater than its parts, as no single component explains the full risk associated with the syndrome. Future research should cover other avenues in order to elucidate the complexity of biological processes linking metabolic syndrome and cancer.

  1. Gut microbiota and metabolic syndrome

    Gut microbiota exerts a significant role in the pathogenesis of the metabolic syndrome, as confirmed by studies conducted both on humans and animal models. Gut microbial composition and functions are strongly influenced by diet. This complex intestinal “superorganism” seems to affect host metabolic balance modulating energy absorption, gut motility, appetite, glucose and lipid metabolism, as well as hepatic fatty storage. An impairment of the fine balance between gut microbes and host’s immune system could culminate in the intestinal translocation of bacterial fragments and the development of “metabolic endotoxemia”, leading to systemic inflammation and insulin resistance. Diet induced weight-loss and bariatric surgery promote significant changes of gut microbial composition, that seem to affect the success, or the inefficacy, of treatment strategies. Manipulation of gut microbiota through the administration of prebiotics or probiotics could reduce intestinal low grade inflammation and improve gut barrier integrity, thus, ameliorating metabolic balance and promoting weight loss. However, further evidence is needed to better understand their clinical impact and therapeutic use. PMID:25473159

    Metabolic syndrome is a clustering of various metabolic parameters, which included diabetes, low high-density lipoprotein cholesterol, elevated triglycerides, abdominal obesity, and hypertension. It has merged as a worldwide epidemic and a major public health care concern. However, due to the different criteria used for the assessment, the frequency of metabolic syndrome in the general population is variable but it more common in the older people. Metabolic syndrome is closely linked to cardiovascular risk and increases cardiovascular outcomes and all-cause mortality. Recent evidences showed that alterations of the thyroid function could have an impact on the components of the metabolic syndrome, suggesting that thyroid hormones have a variety of effects on energy homeostasis, lipid and glucose metabolism, and blood pressure. In this review we summarize available data on the action of thyroid hormone on the components of metabolic syndrome.

    To evaluate patient post-intensive care syndrome (PICS-P) and caregiver burden 3 months after discharge from the Intensive Care Unit (ICU) and determine the impact of different components of PICS-P upon caregiver burden. A prospective observational study was conducted over 26 months (January 2013-February 2015). Medical-surgical ICU and follow-up consultation in Portugal. Patients discharged after a minimum of 2 days in the ICU. Caregiver inclusion criteria: not paid, written and spoken Portuguese, and agreement to participate in the study. In ICU: Patient gender, age, severity of illness (SAPS II) and length of ICU stay. At 3 months caregiver burden, physical (reduced mobility, weakness acquired in the ICU) and psychological components of PICS (anxiety, depression, post-traumatic stress disorder). A total of 168 caregivers completed the survey (response rate of 69%). A low degree of overburden was reported by 34.5% of caregivers, while 15.5% showed moderate to high levels of overburden. Patient anxiety and depression 3 months after ICU discharge significantly influenced the presence of caregiver burden (p=0.030 vs p=0.008). When physical components of PICS-P were evaluated, no influence on caregiver burden was observed. Patient demographics, severity of illness and length of stay also failed to influence caregiver burden. The presence of psychological components of PICS-P 3 months after ICU seems to have a negative impact upon caregiver burden. On the other hand, physical problems showed no important impact upon caregiver overburden. Copyright © 2017 Elsevier España, S.L.U. y SEMICYUC. All rights reserved.

    The first description of patients with clustering of various metabolic abnormalities was as early as 1923 but it was more than five decades later, in 1988, that Reaven coined the term ‘syndrome X’ for this entity. The last two decades have brought forth a number of definitions and criteria to identify this condition. Various studies have demonstrated disparities in these definitions and a few researchers have questioned the utility of these criteria and even the existence of such a syndrome. A few important definitions are reviewed in this paper and, at the end, a simplified clinical definition is given and a simple parameter – lipid accumulation product – is been described that can be used to identify this condition.

    Introduction: Metabolic syndrome predisposes to diabetes and atherosclerotic vascular disease. Statins reduce cardiovascular events, so all metabolic syndrome patients should be evaluated for dyslipidemia. Many patients fail to achieve lipid goals with statin monotherapy. Co-administration of ezetimibe (EZE) and atorvastatin (ATV) may enable more patients to achievelow-density lipoproteincholesterol (LDL-C) goal while avoiding risks of high-dose statin monotherapy. Materials and Methods: The present study compares rosuvastatin (Rsv) with a combination of (Atv) and (Eze). Metabolic syndrome patients, 30-70 years with LDL-C ≥130 mg/dl and a 10-year CHD risk score of 10% were randomized to double-blind treatment with (Rsv) 5 mg (n = 67) or (Atv) 10 mg+(Eze) 10 mg (n = 68) for 12 weeks. Results: LDL-C reduced significantly; (32.3% and 30.3%, P < 0.001) in (Atv)+(Eze) and (Rsv), respectively, but there was no significant difference between two arms. More patients achieved LDL-C goal of ≤100 mg/dl with (Atv)+(Eze) compared to (Rsv) (65% vs. 58%, P < 0.05). Triglycerides (TG) were reduced more with (Atv)+(Eze) compared to (Rsv) (28.1% and 21.4%, P < 0.001). Greater increase in high-density lipoprotein cholesterol (HDL-C) was observed with (Atv)+(Eze). Both treatments were well tolerated. Conclusion: This study shows that the combination of (Atv)+(Eze) has more efficacy and comparable safety to that of (Rsv). PMID:23869305

    Aims Caregiver distress can affect mood and cognition. Meditation can be used to reduce stress. This pilot study explored whether yogic meditation could change regional cerebral metabolism in distressed caregivers. Methods Nine dementia caregivers were randomized to undergo meditation training compared with relaxation for 12 min per day for 8 weeks. Caregivers received neuropsychiatric assessments and brain FDG-PET scans at baseline and postintervention. Results The groups did not differ on measures of mood, mental and physical health, and burden at baseline and follow-up. When comparing the regional cerebral metabolism between groups, significant differences over time were found in the bilateral cerebellum (p < 0.0005), right inferior lateral anterior temporal (p < 0.0005), right inferior frontal (p = 0.001), left superior frontal (p = 0.001), left associative visual (p = 0.002) and right posterior cingulate (p = 0.002) cortices. Conclusion Meditation practice in distressed caregivers resulted in different patterns of regional cerebral metabolism from relaxation. These pilot results should be replicated in a larger study.

    Epinephrine is the prototypical stress hormone. Its stimulation of all α and β adrenergic receptors elicits short-term systolic hypertension, hyperglycemia, and other aspects of the metabolic syndrome. Acute epinephrine infusion increases cardiac output and induces insulin resistance, but removal of the adrenal medulla has no consistent effect on blood pressure. Epinephrine is the most effective endogenous agonist at the β2 receptor. Transgenic mice that cannot make epinephrine and mice that lack the β2 receptor become hypertensive during exercise, presumably owing to the absence of β2-mediated vasodilatation. Epinephrine-deficient mice also have cardiac remodeling and poor cardiac responses to stress, but do not develop resting hypertension. Mice that cannot make epinephrine have a normal metabolism on a regular 14% fat diet but become hyperglycemic and insulin resistant when they eat a high fat diet. Vigorous exercise prevents diabetes in young mice and humans that overeat. However, exercise is a less effective treatment in older type 2 human diabetics and had no effect on glucose or insulin responses in older, diabetic mice. Sensitivity of the β2 receptor falls sharply with advancing age, and adrenal epinephrine release also decreases. However, treatment of older diabetic mice with a β2 adrenergic agonist improved insulin sensitivity, indicating that β2 subsensitivity can be overcome pharmacologically. Recent studies show that over the long term, epinephrine prevents hypertension during stress and improves glucose tolerance. The hyperglycemic influence of epinephrine is short-lived. Chronic administration of epinephrine and other β2 agonists improves cellular glucose uptake and metabolism. Overall, epinephrine counteracts the metabolic syndrome.

    The importance of epigenetic alterations has been acknowledged in cancer for about two decades by an increasing number of molecular oncologists who contributed to deciphering the epigenetic codes and machinery and opened the road for a new generation of drugs now in clinical trials. However, the relevance of epigenetics to common diseases such as metabolic syndrome and cardiovascular disease was less conspicuous. This review focuses on converging data supporting the hypothesis that, in addition to "thrifty genotype" inheritance, individuals with metabolic syndrome (MetS)--combining disturbances in glucose and insulin metabolism, excess of predominantly abdominally distributed weight, mild dyslipidemia and hypertension, with the subsequent development of obesity, type 2 diabetes mellitus (T2D) and cardiovascular disease (CVD)--have suffered improper "epigenetic programing" during their fetal/postnatal development due to maternal inadequate nutrition and metabolic disturbances and also during their life-time. Moreover, as seen for obesity and T2D, MetS tends to appear earlier in childhood, to be more severe from generation to generation and to affect more pregnant women. Thus, in addition to maternal effects, MetS patients may display "transgenerational effects" via the incomplete erasure of epigenetic marks endured by their parents and grandparents. We highlight the susceptibility of epigenetic mechanisms controlling gene expression to environmental influences due to their inherent malleability, emphasizing the participation of transposable elements and the potential role of imprinted genes during critical time windows in epigenetic programming, from the very beginning of development throughout life. Increasing our understanding on epigenetic patterns significance and small molecules (nutrients, drugs) that reverse epigenetic (in) activation should provide us with the means to he obsolete human thrifty genotype into a "squandering" phenotype.

    Metabolic syndrome is a cluster of risk factors associated with an increased risk for cardiovascular disease and type 2 diabetes. Based on data from 1988 to 1994, it is estimated that 24% of adults in the United States meet the criteria for diagnosis of metabolic syndrome. The use of certain medications increases the risk for metabolic syndrome by either promoting weight gain or the development of changes in lipid or glucose metabolism. Diuretics and beta-blockers are among the agents recommended for first-line therapy for hypertension, yet these medications increase the risk of metabolic syndrome. Healthcare providers should recognize and understand the risk associated with antihypertensive agents and should appropriately monitor for changes related to metabolic syndrome. Careful attention to drug choices should be given with patients who are overweight or have other risk factors for diabetes or cardiovascular disease.

    The natural history of metabolic syndrome and polycystic ovary syndrome (PCOS), which shares many components of metabolic syndrome, may originate in intrauterine life. Evidence from epidemiological observations, clinical, and experimental animal studies suggest that the nutritional, hormonal, and metabolic environment afforded by the mother may permanently program differentiating target tissues of the offspring toward the development of metabolic syndrome/PCOS phenotype in adult life. The mechanisms of fetal programming are not well understood. Thus, the altered tissue differentiation may be the result of fetal adaptive responses representing homeostatic adaptations due to alterations in fetal nutrition. Also, tissues under the influence of androgen excess may be directed toward a more masculine phenotype with regard to reproductive, neuroendocrine, and metabolic traits, while the importance of epigenetics in fetal origin of metabolic syndrome/PCOS cannot be overlooked.

    Significance: Epidemiological and animal studies have demonstrated a close link between maternal nutrition and chronic metabolic disease in children and adults. Compelling experimental results also indicate that adverse effects of intrauterine growth restriction on offspring can be carried forward to subsequent generations through covalent modifications of DNA and core histones. Recent Advances: DNA methylation is catalyzed by S-adenosylmethionine-dependent DNA methyltransferases. Methylation, demethylation, acetylation, and deacetylation of histone proteins are performed by histone methyltransferase, histone demethylase, histone acetyltransferase, and histone deacetyltransferase, respectively. Histone activities are also influenced by phosphorylation, ubiquitination, ADP-ribosylation, sumoylation, and glycosylation. Metabolism of amino acids (glycine, histidine, methionine, and serine) and vitamins (B6, B12, and folate) plays a key role in provision of methyl donors for DNA and protein methylation. Critical Issues: Disruption of epigenetic mechanisms can result in oxidative stress, obesity, insulin resistance, diabetes, and vascular dysfunction in animals and humans. Despite a recognized role for epigenetics in fetal programming of metabolic syndrome, research on therapies is still in its infancy. Possible interventions include: 1) inhibition of DNA methylation, histone deacetylation, and microRNA expression; 2) targeting epigenetically disturbed metabolic pathways; and 3) dietary supplementation with functional amino acids, vitamins, and phytochemicals. Future Directions: Much work is needed with animal models to understand the basic mechanisms responsible for the roles of specific nutrients in fetal and neonatal programming. Such new knowledge is crucial to design effective therapeutic strategies for preventing and treating metabolic abnormalities in offspring born to mothers with a previous experience of malnutrition.

    Metabolic syndrome is a constellation of interrelated risk factors of metabolic origin that often accompany obesity and consist of atherogenic dyslipidemia, elevated blood pressure, impaired glucose tolerance, a prothrombotic state, and a proinflammatory state. Using a modification of the criteria by the National Cholesterol Education Program Adult Treatment Panel III, metabolic syndrome in children and adolescents can be clinically diagnosed when three or more of the following are present: body mass index > or = 2 z score, systolic or diastolic blood pressure greater than 95th percentile, triglyceride level greater than 95th percentile, and/or high-density lipoprotein cholesterol less than 5th percentile and impaired glucose tolerance (fasting glucose > 110 mg/dL ). The prevalence of the metabolic syndrome in adolescents has been shown to be 4% overall, but it is 30% to 50% in overweight adolescents. In the United States, 18% to 22% of children and adolescents are overweight; the prevalence of a metabolic syndrome phenotype among US adolescents has also been increasing significantly over the past decade. All of the features of metabolic syndrome are risk factors for atherosclerosis, and metabolic syndrome has been shown to constitute risk for atherosclerotic cardiovascular disease in adults. In children and adolescents with metabolic syndrome, biomarkers of an increased risk of adverse cardiovascular outcomes are already present. Therefore, there is need for prevention and treatment of metabolic syndrome in this population. The mainstay of the treatment is dietary intervention and promotion of active lifestyle to achieve and maintain optimum weight, normal blood pressure, and normal lipid profile for the height and age. The pharmaceutical intervention is usually not required and its long-term outcome has not been studied. There is need for large studies for the management and long-term outcomes of metabolic syndrome in children and adolescents if the future tides

    Metabolic syndrome and its components play an important part in the development of not only cardiovascular conditions, but also digestive and pancreaticobiliary system diseases. The aim of our study is to present a comprehensive overview of the diseases where metabolic syndrome is an inducing risk factor, or where it affects the course of the disease. Metabolic syndrome is a significant risk factor of induction of gastroesophageal reflux and its complication, which is Barretts esophagus. Metabolic syndrome was described as the disease closely linked to idiopathic intestinal inflammations, diseases of the biliary tree and pancreas. Acute pancreatitis, both its development in obese individuals and the burden of its course, are in close correlation with metabolic syndrome, similarly as the course of chronic, mainly alcoholic pancreatitis. Study of non-alcoholic steatopancreatitis presents a challenge, most importantly with regard to the function of pancreatic B cells in obese individuals. Non-alcoholic hepatic steatosis and its forms may as much as lead to the stage of cirrhosis of the liver and they pose a risk of hepatocellular carcinoma. Metabolic syndrome was also described in a population study as a risk factor for carcinoma of the colon. Metabolic syndrome and its components present an important risk factor in relation to inducing some benign as well as malignant gastrointestinal and pancreaticobiliary diseases. A systemic approach to influencing the metabolic syndrome and its components is therefore one of the important approaches to influencing the development and course of not only cardiovascular conditions.

    Metabolic syndrome is an increasing pathology in adults and in children, due to a parallel rise of obesity. Sedentary lifestyle, food habits, cultural influences and also a genetic predisposition can cause dyslipidemia, hypertension, abdominal obesity and insulin resistance which are the two main features of metabolic syndrome. Polycystic ovary syndrome (PCOS) is a condition directly associated with obesity, insulin resistance (HOMA index) and metabolic syndrome, and it is very interesting for its relationship and overlap with the metabolic syndrome. The relationship between the two syndromes is mutual: PCOS women have a higher prevalence of metabolic syndrome and also women with metabolic syndrome commonly present the reproductive/endocrine trait of PCOS. Prevention and treatment of metabolic syndrome and PCOS are similar for various aspects. It is necessary to treat excess adiposity and insulin resistance, with the overall goals of preventing cardiovascular disease and type 2 diabetes and improving reproductive failure in young women with PCOS. First of all, lifestyle changes, then pharmacological therapy, bariatric surgery and laparoscopic ovarian surgery represent the pillars for PCOS treatment.

    From an epidemiological point of view, the metabolic syndrome is a group of risk factors causally, rather than coincidentally, related to insulin resistance. The metabolic syndrome is a condition with relatively high prevalence rates in both the Czech Republic and in other developed countries. There is a clear trend of increasing prevalence in both sexes depending on age. In the Czech Republic, the syndrome is less common in females (25.5%) than in males (37.6%). Epidemiological studies found white (Europoid race) males to be at higher risk due to abdominal obesity. The definition of the metabolic syndrome has evolved over time and helps to identify individuals at high risk of developing cardiovascular disease and type 2 diabetes, hence the use of the term cardiometabolic syndrome. Early detection of metabolic syndrome symptoms including insulin resistance should be performed mainly by general practitioners as part of regular check-ups.

    Introduction Metabolic syndrome is comprised of a combination of the following states: increased insulin resistance, dyslipidemia, cardiovascular disease, and increased abdominal obesity. Women with polycystic ovary syndrome (PCOS) have an increased risk of developing metabolic syndrome over the course of their lives. Metabolic syndrome increases risk of major cardiovascular events, morbidity, quality of life, and overall health care costs. Though metabolic syndrome in women with PCOS is an area of great concern, there is no effective individual medical therapeutic to adequately treat this issue. Areas Covered This article will review key aspects of metabolic syndrome in PCOS. We will discuss classic and novel therapeutics to address metabolic syndrome in women with PCOS. We will conclude with the importance of developing strategic interventions to increase the compliance to lifestyle and dietary modification, in addition to appreciation of the emerging pharmaceutical therapeutics available. Expert Opinion Innovation in lifestyle modification, including diet, exercise, with and without dedicated stress reduction techniques is the future in treatment of metabolic syndrome in PCOS. Application of novel interventions, such as group medical care, may improve future adherence to lifestyle modification recommendations, in addition to or in combination with pharmaceutical therapeutics.

    Rheumatoid arthritis (RA) generally affects people between the ages of 20 and 50. Patients with RA have a significantly higher prevalence of the metabolic syndrome (MS) compared to the general population. The increased cardiovascular risk (CVR) associated with RA places this disease among the most widely studied. The duration of RA was associated with MS, implicating the role of inflammation in MS development. The presence of MS correlates with increased subclinical atherosclerosis. A positive correlation between prevalence of MS and worsening of functional status was found in patients with RA. Patients with rheumatoid arthritis have an increased risk and a higher mortality from cardiovascular diseases (CVD), the rheumatologist should be aware of those MS risk factors and attempt to modify them. This review summarizes recent advances in the field of MS in RA.

    The epidemic prevalence of obesity and its related metabolic disorders (e.g.: diabetes, metabolic syndrome) represents a challenge for next upcoming years, for caregivers and for the health care system globally. Early prevention strategies for type 2 diabetes have been studied and their efficacy has been proven. Moreover there is emerging evidence that childhood obesity is associated with previous exposition to fetal hyperglycemia. Prevention of metabolic troubles may thus consist not only in an early intervention for lifestyle modifications, but also in an effort to identify conditions, such as Gestational Diabetes Mellitus, that seems to have a strong impact on the metabolic imprinting in the future generation.

  8. Metabolic Syndrome and Renal Injury

    Both metabolic syndrome (MetS) and chronic kidney disease (CKD) are major global health issues. Current clinical markers used to reflect renal injury include albuminuria and estimated glomerular filtration rate (eGFR). Given the same eGFR level, urine albumin might be a better risk marker to predict progression of CKD and future development of cardiovascular diseases (CVDs). Serum Cystatin C is emerging as a new biomarker for early detection of renal injury associated with MetS and cardiovascular risk. In addition to each component, MetS per se influences the incidence and prognosis of renal injury and the odds ratios increased with the increase in the number of metabolic abnormalities. Hyperinsulinemia, activation of rennin-angiotensin-aldosterone system, increase of oxidative stress, and inflammatory cytokines are proposed to be the plausible biological link between MetS and CKD. Weight control, stick control of blood pressure, glucose, and lipids disorders may lead to lessening renal injury and even the subsequent CVD. PMID:21461396

    Following on from impressive economic development and urbanization, China is currently experiencing a high prevalence of metabolic syndrome. Patients with metabolic syndrome suffer from the "The Deadly Quartet" of hyperglycemia, hypertriglyceridemia, hypertension, and central (or upper body) obesity. Current treatment strategies directed towards metabolic syndrome tend to be limited to just one of these four conditions, so developing novel drugs to target multiple metabolic abnormalities could be preferable to current approaches. New insights suggest benefits of natural agents as treatments for metabolic syndrome. Herein, we review the evidence for using nine such agents developed on the basis of traditional medicine or herbal preparations. © 2010 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and Blackwell Publishing Asia Pty Ltd.

    2015-05-01

    Metabolic syndrome is closely associated with morbid obesity and leads to increased risk of cardiovascular diseases and related mortality. Bariatric surgery is considered an effective option for the management of this condition. We searched MEDLINE, Current Contents, and the Cochrane Library for papers published on bariatric surgery outcomes in English from January 1, 1990, to April 20, 2014. Bariatric surgery can significantly reduce body weight, resolve or cure many of the symptoms of metabolic syndrome, including type 2 diabetes, hypertension, hyperlipidemia, and improve long-term survival. Surgery, in addition to existing therapy, could therefore be considered as an optimal treatment for patients with metabolic syndrome and morbid obesity.

    2011-01-01

    People with HIV infection have metabolic abnormalities that resemble metabolic syndrome (hypertriglyceridemia, low high-density lipoprotein cholesterol, and insulin resistance), which is known to predict increased risk of cardiovascular disease (CVD). However, there is not one underlying cause for these abnormalities and they are not linked to each other. Rather, individual abnormalities can be affected by the host response to HIV itself, specific HIV drugs, classes of HIV drugs, HIV-associated lipoatrophy, or restoration to health. Furthermore, one component of metabolic syndrome, increased waist circumference, occurs less frequently in HIV infection. Thus, HIV infection supports the concept that metabolic syndrome does not represent a syndrome based on a common underlying pathophysiology. As might be predicted from these findings, the prevalence of CVD is higher in people with HIV infection. It remains to be determined whether CVD rates in HIV infection are higher than might be predicted from traditional risk factors, including smoking. PMID:18366987

    2014-01-01

    There is increasing evidence that impaired glucose tolerance (IGT) or metabolic syndrome may result in peripheral nerve injury, although the exact relationship between the conditions is still being characterized. There is animal model, epidemiologic, and clinical evidence to suggest a pathophysiologic relationship between neuropathy and metabolic syndrome, along with its components including obesity, dyslipidemia, and insulin resistance. IGT and metabolic syndrome are associated with subclinical nerve damage or are typically painful and sensory predominant, although autonomic involvement may also occur. Because there is often preferential small fiber injury and nerve conduction studies may be relatively insensitive, skin biopsy with assessment of intraepidermal nerve fiber density is often used to confirm the diagnosis. Treatment of metabolic syndrome and IGT-associated neuropathies should include diet and exercise counseling, maintenance of normoglycemia, and targeted pharmacologic therapy for modifiable risk factors. Further research is required to fully elucidate the complex pathophysiology, as well as identify optimal diagnostic and treatment approaches.

    The metabolic syndrome refers to the co-occurrence of several known cardiovascular risk factors, including insulin resistance, obesity, atherogenic dyslipidemia and hypertension. These conditions are interrelated and share underlying mediators, mechanisms and pathways. There has been recent controversy about its definition and its utility. In this article, I review the current definitions for the metabolic syndrome and why the concept is important. It identifies a subgroup of patients with shared pathophysiology who are at high risk of developing cardiovascular disease and type 2 diabetes. By considering the central features of the metabolic syndrome and how they are related, we may better understand the underlying pathophysiology and disease pathogenesis. A comprehensive definition for the metabolic syndrome and its key features would facilitate research into its causes and hopefully lead to new insights into pharmacologic and lifestyle treatment approaches.

  16. Pediatric Metabolic Syndrome: Pathophysiology and Laboratory Assessment.

    PubMed

    2017-03-01

    Pediatric overweight and obesity is an emerging public health priority as rates have rapidly increased worldwide. Obesity is often clustered with other metabolic abnormalities including hypertension, dyslipidemia, and insulin resistance, leading to increased risk of cardiovascular disease. This cluster of risk factors, termed the metabolic syndrome, has traditionally been reported in adults. However, with the increased prevalence of pediatric obesity, the metabolic syndrome is now evident in children and adolescents. This complex cluster of risk factors is the result of the pathological interplay between several organs including adipose tissue, muscle, liver, and intestine with a common antecedent - insulin resistance. The association of the metabolic syndrome with several systemic alterations that involve numerous organs and tissues adds to the complexity and challenge of diagnosing the metabolic syndrome and identifying useful clinical indicators of the disease. The complex physiology of growing and developing children and adolescents further adds to the difficulties in standardizing laboratory assessment, diagnosis, and prognosis for the diverse pediatric population. However, establishing a consensus definition is critical to identifying and managing children and adolescents at high risk of developing the metabolic syndrome. As a result, the examination of novel metabolic syndrome biomarkers which can detect these metabolic abnormalities early with high specificity and sensitivity in the pediatric population has been of interest. Understanding this complex cluster of risk factors in the pediatric population is critical to ensure that this is not the first generation where children have a shorter life expectancy than their parents. This review will discuss the pathophysiology, consensus definitions and laboratory assessment of pediatric metabolic syndrome as well as potential novel biomarkers.

    The metabolic syndrome (MetS) is defined as the concurrence of obesity-associated cardiovascular risk factors including abdominal obesity, impaired glucose tolerance, hypertriglyceridemia, decreased HDL cholesterol, and/or hypertension. Earlier conceptualizations of the MetS focused on insulin resistance as a core feature, and it is clearly coincident with the above list of features. Each component of the MetS is an independent risk factor for cardiovascular disease and the combination of these risk factors elevates rates and severity of cardiovascular disease, related to a spectrum of cardiovascular conditions including microvascular dysfunction, coronary atherosclerosis and calcification, cardiac dysfunction, myocardial infarction, and heart failure. While advances in understanding the etiology and consequences of this complex disorder have been made, the underlying pathophysiological mechanisms remain incompletely understood, and it is unclear how these concurrent risk factors conspire to produce the variety of obesity-associated adverse cardiovascular diseases. In this review, we highlight current knowledge regarding the pathophysiological consequences of obesity and the MetS on cardiovascular function and disease, including considerations of potential physiological and molecular mechanisms that may contribute to these adverse outcomes.

    The metabolic syndrome is a constellation of risk factors that contribute to the onset of type 2 diabetes mellitus and cardiovascular disease (CVD). CVD has been identified by the National Cholesterol Education Program (NCEP) as the primary clinical outcome of the metabolic syndrome. Although no algorithm is currently available for estimating the absolute risk of CVD for patients with the metabolic syndrome, screening for cardiovascular (CV) risk in these patients involves testing for lipoprotein abnormalities (namely, an analysis of specific low-density lipoprotein particle numbers) and an assessment of various surrogate markers for subclinical coronary artery disease. Such screening can be used to help predict the development of CVD and thereby allow for effective interventions to help prevent coronary events. Strategies for reducing CV risk in patients with the metabolic syndrome are multifactorial. In addition to placing an emphasis on therapeutic lifestyle changes that increase levels of physical activity, dietary modification, and weight reduction, several pharmacologic therapies are available. One novel approach for managing CV risk in patients with the metabolic syndrome involves the inhibition of the endocannabinoid system, including the use of rimonabant. A review of CV risk factors in patients with the metabolic syndrome is beneficial for clinicians to apply in the care of their patients, along with a discussion about strategies for identifying at-risk patients and managing CVD risk for these patients.

    In Central and Eastern European countries, cardiovascular disorders (CVD) in middle age are much more common than in Western Europe, and it is imperative to understand the causes underlying this excess disease burden. The metabolic syndrome comprises a constellation of metabolic abnormalities that increase the risk of cardiovascular disease. Data were obtained by structured interview, and by measurements of anthropometric factors and blood analyses among 3,862 individuals. Metabolic syndrome was defined according the International Diabetes Federation Task Force on Epidemiology and Prevention, as the presence of at least 3 of 5 abnormalities: 1) abdominal obesity, 2) glucose intolerance, 3) high triglycerides, 4) low HDL cholesterol, 5) high blood pressure. Overall, 1,518 participants (39.5%) had metabolic syndrome. The prevalence among females was 34.3% (877 females) vs. 49.9% (641 males) among males, and increased with age in both genders. Abdominal obesity was the most common abnormality (2,897 participants, 75.1%), followed by high blood pressure (2,741 participants, 71%), glucose intolerance (1,437 participants, 37.3%), elevated triglycerides (817 participants, 21.2%) and low HDL (615 participants, 15.9%). The prevalence of metabolic syndrome and metabolic abnormalities is high and represents strong risk factors for CVD morbidity and mortality. However, these factors are all potentially preventable by lifestyle modification and/or by pharmacological treatment. There is an urgent need for the health service to act, and to increase public awareness of metabolic syndrome.

    High blood pressure in subjects with the metabolic syndrome (MS) is largely related to dietary salt. We investigated in free-living men and women whether increase in dietary salt intake is associated with the presence and severity of the MS. A total of 766 subjects (251M, 515F) of 44.9+/-0.5 years/age and SBP/DBP of 120+/-0.6/77+/-0.4 mmHg were studied. Twenty-four hour urinary sodium (UNa(+)) and potassium (UK(+)) excretions were 143+/-2.5 mmol (median: 131.5) and 48+/-0.9 mmol (median: 44). UNa(+) was higher in men than in women (median: 155.5 vs. 119.8 mmol/day; P<0.0001). UK(+) (r=0.34; P<0.0001), measures of obesity (r=0.26; P<0.0001) and BP (r=0.15; P<0.0001) were significantly associated with UNa(+). The association with BP was lost after adjusting for weight. Of the 766 subjects, 256 (33.4%) met the NCEP-ATPIII criteria for the MS. Median UNa(+) in men and women with no traits of the MS was 140 and 116.7 mmol/day, respectively (P<0.001), increasing to 176 in men and 135 mmol/day in women with 4-5 components of the syndrome (P<0.001). Weight, BMI and waist increased significantly across the quartiles of UNa(+) both in men and women; whereas, age, lipids and fasting glucose did not. SBP and DBP were associated with UNa(+) in men but not in women. UK(+) correlated with age in men and women (r=023; P<0.0001) and with obesity in women (r=0.14; P=0.001). UNa(+) a measure of dietary sodium intake in free-living subjects was markedly increased in subjects with the MS. Higher UNa(+) was associated with obesity and higher BP, but not with age, dyslipidemia or fasting glucose.

    2017-08-26

    The complexity of gout continues to unravel with each new investigation. Gout sits at the intersection of multiple intrinsically complex processes, and its prevalence, impact on healthcare costs, and association with important co-morbidities make it increasingly relevant. The association between gout and type 2 diabetes, hypertension, hyperlipidemia, cardiovascular disease, renal disease, and obesity suggest that either gout, or its necessary precursor hyperuricemia, may play an important role in the manifestations of the metabolic syndrome. In this review, we analyze the complex interconnections between gout and metabolic syndrome, by reviewing gout's physiologic and epidemiologic relationships with its major co-morbidities. Increasing evidence supports gout's association with metabolic syndrome. More specifically, both human studies and animal models suggest that hyperuricemia may play a role in promoting inflammation, hypertension and cardiovascular disease, adipogenesis and lipogenesis, insulin and glucose dysregulation, and liver disease. Fructose ingestion is associated with increased rates of hypertension, weight gain, impaired glucose tolerance, and dyslipidemia and is a key driver of urate biosynthesis. AMP kinase (AMPK) is a central regulator of processes that tend to mitigate against the metabolic syndrome. Within hepatocytes, leukocytes, and other cells, a fructose/urate metabolic loop drives key inhibitors of AMPK, including AMP deaminase and fructokinase, that may tilt the balance toward metabolic syndrome progression. Preliminary evidence suggests that agents that block the intracellular synthesis of urate may restore AMPK activity and help maintain metabolic homeostasis. Gout is both an inflammatory and a metabolic disease. With further investigation of urate's role, the possibility of proper gout management additionally mitigating metabolic syndrome is an evolving and important question.

    Metabolic syndrome is a clustering of several cardiovascular risk factors. Contrary to earlier thoughts, metabolic syndrome is no longer rare in Africa. The prevalence is increasing, and it tends to increase with age. This increase in the prevalence of metabolic syndrome in the continent is thought to be due to departure from traditional African to western lifestyles. In Africa, it is not limited to adults but is also becoming common among the young ones. Obesity and dyslipidemia seem to be the most common occurring components. While obesity appears more common in females, hypertension tends to be more predominant in males. Insulin resistance has remained the key underlying pathophysiology. Though pharmacologic agents are available to treat the different components of the syndrome, prevention is still possible by reverting back to the traditional African way of life. PMID:22276253

It is also a risk factor for dyslipidemia, metabolic syndrome and non-alcoholic fatty liver disease. The pathological mechanisms underlying these associations remain to be precisely discovered, but intermittent hypoxia is probably one of the major factors. The place of obstructive apnea treatment in the management of metabolic conditions remains unclear. Copyright © 2016 SPLF. Published by Elsevier Masson SAS. All rights reserved.

    Worldwide, breast cancer is the most frequently diagnosed life-threatening cancer in women and the most important cause of cancer-related deaths among women. This disease is on the rise in Turkey. Metabolic syndrome is a cluster of metabolic disturbances including insulin resistance, dyslipidemia, hypertension, abdominal obesity and high blood sugar. Several studies have examined the association of the individual components of the metabolic syndrome with breast cancer. More recent studies have shown it to be an independent risk factor for breast cancer. It has also been associated with poorer prognosis, increased incidence, a more aggressive tumor phenotype. Basic research studies are now in progress to illuminate the molecular pathways and mechanisms that are behind this correlation. Given the fact that all of the components of metabolic syndrome are modifiable risk factors, preventive measures must be established to improve the outcome of breast cancer patients. In this review we set the background by taking into account previous studies which have identified the components of metabolic syndrome individually as breast cancer risk factors. Then we present the latest findings which elaborate possible explanations regarding how metabolic syndrome as a single entity may affect breast cancer risk.

    2016-01-01

    The metabolic syndrome (MetS) is comprised of a cluster of closely related risk factors, including visceral adiposity, insulin resistance, hypertension, high triglyceride, and low high-density lipoprotein cholesterol; all of which increase the risk for the development of type 2 diabetes and cardiovascular disease. A chronic state of inflammation appears to be a central mechanism underlying the pathophysiology of insulin resistance and MetS. In this review, we summarize recent research which has provided insight into the mechanisms by which inflammation underlies the pathophysiology of the individual components of MetS including visceral adiposity, hyperglycemia and insulin resistance, dyslipidemia, and hypertension. On the basis of these mechanisms, we summarize therapeutic modalities to target inflammation in the MetS and its individual components. Current therapeutic modalities can modulate the individual components of MetS and have a direct anti-inflammatory effect. Lifestyle modifications including exercise, weight loss, and diets high in fruits, vegetables, fiber, whole grains, and low-fat dairy and low in saturated fat and glucose are recommended as a first line therapy. The Mediterranean and dietary approaches to stop hypertension diets are especially beneficial and have been shown to prevent development of MetS. Moreover, the Mediterranean diet has been associated with reductions in total and cardiovascular mortality. Omega-3 fatty acids and peroxisome proliferator-activated receptor α agonists lower high levels of triglyceride; their role in targeting inflammation is reviewed. Angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and aldosterone blockers comprise pharmacologic therapies for hypertension but also target other aspects of MetS including inflammation. Statin drugs target many of the underlying inflammatory pathways involved in MetS. Copyright © 2016 Elsevier Inc. All rights reserved.

    Objectives: The study aimed to describe the prevalence of metabolic syndrome (MS) and its components among Omani adults. Methods: The 2008 Oman World Health Survey dataset was used to determine the national prevalence of MS. Logistic regression using all key sociodemographic, clinical and behavioural variables was used to identify the associations of independent variables with MS. Results: The age-adjusted prevalence of MS was 23.6%. MS was significantly associated with age, marital and work status and wealth level. MS was more common for people aged 50 years and older compared to the youngest cohort (OR 3.6, CI: 2.4–5.3; P <0.001) and in people who were married or employed (OR 1.6, CI: 1.3–2.1; P <0.001 and OR 1.3, CI: 1.1–1.8; P = 0.043, respectively) compared to their unmarried and unemployed counterparts. MS was also more common in people in the second lowest wealth quintile (OR 1.6, CI: 1.2–2.2; P = 0.05) compared to the lowest quintile and in those who sat for more than six hours per day (OR 1.3, CI: 1.1–1.7; P = 0.035). Conclusion: One in four adults had MS in Oman. This may fuel the epidemic of non-communicable diseases (NCDs) in Oman, particularly given the increasingly elderly population. Urgent action is required to ensure quality patient care at all levels of the healthcare system. Further research on behavioural risk factors is needed. Developing and implementing a multisectoral strategy to prevent NCDs should be at the top of the current health agenda for Oman. PMID:25364547

    There is a relationship between the state of the cardiovascular system and metabolic syndrome (MS). A way to diagnose the heart state of a person is to monitor the electrical activity of the heart using a 24 hours Holter monitor. Scanned ECG signal can be analyzed beat-by-beat by algorithms that separate normal of abnormal heartbeats. If the percentage of abnormal heartbeats is too high it could be argued that the patient has heart problems. We have algorithms that can not only identify the abnormal heartbeats, but they can also classify them, so we classified and counted abnormal heartbeats in patients with MS and subjects without MS. Most of our patients have large waist circumference, high triglycerides and high levels of LDL (high-density lipoprotein) cholesterol although some of them have high blood pressure. We enrolled adult patients with MS free of diabetes in a four month lifestyle intervention program including diet and physical aerobic exercise, and compared with healthy controls. We made an initial registration with a Holter, and 24 hours ECG signal is analyzed to identify and classify the different types of heartbeats. The patients then begin with diet or exercise (at least half an hour daily). Periodically Holter records were taken up and we describe the evolution in time of the number and type of abnormal heartbeats. Results show that the percentage of abnormal heartbeats decreases over time, in some cases the decline is very significant, and almost a reduction to half or less of abnormal heartbeats after several months since the patients changed their eating or physical activity habits.

    Metabolic syndrome is associated with increased risk for cardiovascular and cerebrovascular disease. The World Health Organization and National Cholesterol Education Program Adult Treatment Panel III have identified physiologic abnormalities associated with metabolic syndrome, including impaired glucose metabolism, high blood pressure, elevated cholesterol levels, and abdominal obesity. It is estimated that 47 million Americans have metabolic syndrome. A variety of therapies may help reduce the incidence and risk, including diet, weight loss, physical exercise, glycemic control, and pharmacological treatments. Nursing care is focused on developing an individualized plan of care that includes family members and providing education, psychosocial support, close monitoring, and continued follow-up to ensure adherence and success in achieving patient outcomes.

    Metabolic syndrome is an important etiologic factor in the development of certain types of cancers. The economic cost of the treatment of cancer has been steadily increasing. We therefore estimated the economic burden of cancers attributable to metabolic syndrome in Korea. We reviewed metabolic syndrome-related cancers and relative risk and then calculated population attributable fractions. We analyzed insurance claims data for metabolic syndrome-related cancers in 2012 in order to estimate the direct costs associated with these cancers, including hospitalization, outpatient visits, transportation costs, and caregivers' costs as well as indirect costs such as loss of productivity due to cancer treatment and premature death. In 2012, 18,070 patients in Korea had cancers attributable to metabolic syndrome. The economic burden was USD 199.8 million and the direct and indirect costs were USD 124.5 million and USD 75.3 million, respectively. We estimated the economic burden of cancers attributable to metabolic syndrome in Korea and the efforts are necessary to reduce this burden.

    The metabolic syndrome or cardiovascular dysmetabolic syndrome is characterized by obesity, central obesity, insulin resistance, atherogenic dyslipidemia, and hypertension. The major risk factors leading to this syndrome are physical inactivity and an atherogenic diet and cornerstone clinical feature is abdominal obesity or adiposity. In addition, patients usually have elevated triglycerides, low HDL cholesterol, elevated LDL cholesterol, other abnormal lipid parameters, hypertension, and elevated fasting blood glucose. Impaired fibrinolysis, increased susceptibility to thrombotic events, and raised inflammatory markers are also observed. Given that India has the largest number of subjects with type-2 diabetes in the world it can be extrapolated that this country also has the largest number of patients with the metabolic syndrome. Epidemiological studies confirm a high prevalence. Therapeutic approach involves intervention at a macro-level and control of multiple risk factors using therapeutic lifestyle approaches (diet control and increased physical activity, pharmacotherapy - anti-obesity agents) for control of obesity and visceral obesity, and targeted approach for control of individual risk factors. Pharmacological therapy is a critical step in the management of patients with metabolic syndrome when lifestyle modifications fail to achieve the therapeutic goals. Anti-obesity drugs such as sibutramine and orlistat can be tried to reduce weight and central obesity and jointly control the metabolic syndrome components. Other than weight loss, there is no single best therapy and treatment should consist of treatment of individual components of the metabolic syndrome. Newer drugs such as the endocannabinoid receptor blocker,rimonabant, appear promising in this regard. Atherogenic dyslipidemia should be controlled initially with statins if there is an increase in LDL cholesterol. If there are other lipid abnormalities then combination therapy of statin with fibrates

    Though severe or refractory asthma merely affects less than 10% of asthma population, it consumes significant health resources and contributes significant morbidity and mortality. Severe asthma does not fell in the routine definition of asthma and requires alternative treatment strategies. It has been observed that asthma severity increases with higher body mass index. The obese-asthmatics, in general, have the features of metabolic syndrome and are progressively causing a significant burden for both developed and developing countries thanks to the westernization of the world. As most of the features of metabolic syndrome seem to be originated from central obesity, the underlying mechanisms for metabolic syndrome could help us to understand the pathobiology of obese-asthma condition. While mitochondrial dysfunction is the common factor for most of the risk factors of metabolic syndrome, such as central obesity, dyslipidemia, hypertension, insulin resistance, and type 2 diabetes, the involvement of mitochondria in obese-asthma pathogenesis seems to be important as mitochondrial dysfunction has recently been shown to be involved in airway epithelial injury and asthma pathogenesis. This review discusses current understanding of the overlapping features between metabolic syndrome and asthma in relation to mitochondrial structural and functional alterations with an aim to uncover mechanisms for obese-asthma.

    Vitamin D is essential in bone mineralization and calcium homeostasis, and an increasing body of evidence suggests that vitamin D may be important for maintaining extraskeletal health, including having beneficial effects on cardiometabolic outcomes. Vitamin D deficiency is widespread, but the role of vitamin D in the metabolic syndrome is not fully elucidated. In this review we summarize data from observational studies and randomized controlled trials on the relation between vitamin D and the metabolic syndrome and its components. A large number of observational studies suggest a relationship between low levels of 25(OH)D and the metabolic syndrome or its individual clinical features. Randomized controlled trials of vitamin D supplementation addressing aspects of the metabolic syndrome have yielded inconsistent results, and many studies suffer from methodological limitations. There is an urgent need for large, well-designed randomized controlled trials with relevant endpoints. Until definitive results from such studies are available, caution should be taken towards the use of vitamin D-supplementation for disorders other than musculoskeletal system. New molecular biological techniques elucidating the interaction between the active vitamin D derivatives and target genes represent a promising approach to more precise knowledge about new biomedical function, which also might shed light on the complex metabolic syndrome.

    The objective of this study was to investigate factors related to family functioning and adaptation in caregivers of individuals with Rett syndrome (RS). A cross-sectional quantitative survey explored the relationships between demographics, parental self-efficacy, coping methods, family functioning and adaptation. A forward-backward, step-wise model selection procedure was used to evaluate variables associated with both family functioning and adaptation. Analyses also explored family functioning as a mediator of the relationship between other variables and adaptation. Bivariate analyses (N=400) revealed that greater parental self-efficacy, a greater proportion of problem-focused coping, and a lesser proportion of emotion-focused coping were associated with more effective family functioning. In addition, these key variables were significantly associated with greater adaptation, as was family functioning, while controlling for confounders. Finally, regression analyses suggest family functioning as a mediator of the relationships between three variables (parental self-efficacy, problem-focused coping, and emotion-focused coping) with adaptation. This study demonstrates the potentially predictive roles of expectations and coping methods and the mediator role of family functioning in adaptation among caregivers of individuals with RS, a chronic developmental disorder. A potential target for intervention is strengthening of caregiver competence in the parenting role to enhance caregiver adaptation. Published by Elsevier Ireland Ltd.

    CBI endocannabinoid system receptors localized in the hypothalamus and the nucleus accumbens are known to regulate hunger. Hyperstimulation of the CBI receptors lead to an increase of food intake, but also to an increase of lipogenesis, decrease of adiponectin and increase of insulin resistance. Rimonabant is the first CBI central and peripheral blocker, tested in international trials (RIO-lipids, RIO-Europe and RIO-North America). Significant results on weight reduction, increased adiponectin and improved metabolic syndrome have been demonstrated. Rimonabant is a new pharmacological therapy and very interesting for tackling obesity and metabolic syndrome.

    In spite of the lack of a uniform definition for metabolic syndrome in pediatry, recent studies have shown that it develops during childhood and is highly prevalent among children and adolescents who suffer from obesity. In light of the current epidemic of obesity in this age category in western countries, and specifically in Mexico, it becomes essential to know the means to prevent, detect and treat this syndrome. Nurses play an important role in promoting childhood health with regards to metabolic syndrome. To put into practice the strategies which resolve underlying problems related with this syndrome is a priority for the well-being of this age group. These strategies should include the application and management of public policies; the collaboration by health services, social services and schools; but, furthermore, the prevention and the management of this syndrome require a family commitment, while the changes in living habits benefit the entire family. This review article proposes to introduce prevention, diagnostic and treatment strategies which nursing personnel can carry out while dealing with metabolic syndrome in adolescents.

    Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women and the leading cause of anovulatory infertility. The prevalence of the syndrome ranges between 6 to 15% based on broader Rotterdam diagnostic criteria verses strict NIH diagnostic criteria.1 The condition is characterized by a combination of ovulatory dysfunction, hyperandrogenism and the presence of polycystic ovaries. PCOS has been associated with multiple metabolic alterations and consequences including impaired glucose tolerance, insulin resistance, hyperinsulinemia, type II diabetes, dyslipidemia, metabolic syndrome, obesity and subclinical cardiovascular disease. It remains unclear however if these associations lead to an increased risk of clinically significant long-term cardiovascular disease. Large prospective studies to date have not detected significant differences in overall cardiovascular morbidity and mortality in PCOS. The phenotypical variability in PCOS has made researching each of these associations challenging as different aspects of the syndrome may be contributing, opposing or confounding factors. The ability to detect significant differences in long-term cardiovascular outcomes may also be due to the variable nature of the syndrome. In this review, we attempt to describe a summary of the current literature concerning the metabolic alterations and cardiovascular consequences of polycystic ovary syndrome.

    [Purpose] The aim of this study was to explore lifestyle factors in relation to metabolic syndrome so as to be able to utilize the results as baseline data for the furtherance of health-care and medical treatment. [Subjects and Methods] This study was conducted with patients who visited a health care center located in Seoul and had abdominal ultrasonography between 2 March 2013 and 28 February, 2014. Heights, weights, and blood pressures were measured by automatic devices. Three radiologists examined the patients using abdominal ultrasonography for gallstone diagnosis. The statuses of patients with regard to smoking, alcohol, coffee, and physical activities were explored for the lifestyle investigation. For investigating baseline demographics, we first used descriptive statistics. We then used the χ2 test to analyze lifestyles and gallstone prevalence with regard to the presence of metabolic syndrome. Lastly, logistic regression analysis was conducted to discover the risk factors of metabolic syndrome. [Results] For men, body mass index, maximum gallstone size, and waist circumference were revealed as risk factors for metabolic syndrome, in descending order of the degree of risk. For females, gallstone presence was the most significant risk factor, followed by waist circumference. [Conclusion] Metabolic disease mainly presents itself along with obesity, and we should become more focused on preventing and treating this disease. A large-scale prospective study is needed in the future, as the cause of nonalcoholic steatohepatitis remained unclear in this study. PMID:26957725

    The worldwide epidemic of childhood obesity in the last decades is responsible for the occurrence in pediatrics of disorders once mainly found in adults, such as the metabolic syndrome. A key factor in the pathogenesis of metabolic syndrome is insulin resistance, a phenomenon occurring mainly in obese subjects with a general resistance to the insulin effect only on carbohydrates metabolism. Given that the metabolic syndrome is driven by obesity, the prevalence of the latter will strongly influence the prevalence of metabolic syndrome. This article addresses the causes of metabolic syndrome and the relevance of obesity in the pediatric population. Copyright © 2011 Elsevier Inc. All rights reserved.

  2. A Comprehensive Review on Metabolic Syndrome

    PubMed Central

    2014-01-01

    Metabolic syndrome is defined by a constellation of interconnected physiological, biochemical, clinical, and metabolic factors that directly increases the risk of cardiovascular disease, type 2 diabetes mellitus, and all cause mortality. Insulin resistance, visceral adiposity, atherogenic dyslipidemia, endothelial dysfunction, genetic susceptibility, elevated blood pressure, hypercoagulable state, and chronic stress are the several factors which constitute the syndrome. Chronic inflammation is known to be associated with visceral obesity and insulin resistance which is characterized by production of abnormal adipocytokines such as tumor necrosis factor α, interleukin-1 (IL-1), IL-6, leptin, and adiponectin. The interaction between components of the clinical phenotype of the syndrome with its biological phenotype (insulin resistance, dyslipidemia, etc.) contributes to the development of a proinflammatory state and further a chronic, subclinical vascular inflammation which modulates and results in atherosclerotic processes. Lifestyle modification remains the initial intervention of choice for such population. Modern lifestyle modification therapy combines specific recommendations on diet and exercise with behavioural strategies. Pharmacological treatment should be considered for those whose risk factors are not adequately reduced with lifestyle changes. This review provides summary of literature related to the syndrome's definition, epidemiology, underlying pathogenesis, and treatment approaches of each of the risk factors comprising metabolic syndrome.

    The metabolic syndrome (MetS) represents a cluster of cardiometabolic risk factors, including central obesity, insulin resistance, glucose intolerance, dyslipidemia, hypertension, hyperinsulinemia and microalbuminuria, and more recently, nonalcoholic fatty liver disease (NAFLD), polycystic ovarian syndrome (PCOS) and atherosclerosis. Although the concept of the MetS is subject to debate due to lack of a unifying underlying mechanism, the prevalence of a metabolic syndrome phenotype is rapidly increasing worldwide. Moreover, it is increasingly prevalent in children and adolescents of obese mothers. Evidence from both epidemiological and experimental animal studies now demonstrates that MetS onset is increasingly likely following exposure to suboptimal nutrition during critical periods of development, as observed in maternal obesity. Thus, the developmental priming of the MetS provides a common origin for this multifactorial disorder. Consequently, the mechanisms leading to this developmental priming have recently been the subject of intensive investigation. This review discusses recent data regarding the epigenetic modifications resulting from nutrition during early development that mediate persistent changes in the expression of key metabolic genes and contribute toward an adult metabolic syndrome phenotype. In addition, this review considers the role of the endogenous molecular circadian clock system, which has the potential to act at the interface between nutrient sensing and epigenetic processing. A continued and greater understanding of these mechanisms will eventually aid in the identification of individuals at high risk of cardiovascular disease (CVD) and type 2 diabetes, and help develop therapeutic interventions, in accordance with current global government strategy.

    Metabolic syndrome is a cluster of metabolic and cardiovascular symptoms: insulin resistance (IR), obesity, dyslipemia. Hypertension and vascular disorders are central to this syndrome. After a brief historical review, we discuss the role of sympathetic tone. Subsequently, we examine the link between endothelial dysfunction and IR. NO is involved in the insulin-elicited capillary vasodilatation. The insulin-signaling pathways causing NO release are different to the classical. There is a vasodilatory pathway with activation of NO synthase through Akt, and a vasoconstrictor pathway that involves the release of endothelin-1 via MAPK. IR is associated with an imbalance between both pathways in favour of the vasoconstrictor one. We also consider the link between hypertension and IR: the insulin hypothesis of hypertension. Next we discuss the importance of perivascular adipose tissue and the role of adipokines that possess vasoactive properties. Finally, animal models used in the study of vascular function of metabolic syndrome are reviewed. In particular, the Zucker fatty rat and the spontaneously hypertensive obese rat (SHROB). This one suffers macro- and microvascular malfunction due to a failure in the NO system and an abnormally high release of vasoconstrictor prostaglandins, all this alleviated with glitazones used for metabolic syndrome therapy.

    There has been an increasing prevalence of kidney stones over the last 2 decades worldwide. Many studies have indicated a possible association between metabolic syndrome and kidney stone disease, particularly in overweight and obese patients. Many different definitions of metabolic syndrome have been suggested by various organizations, although the definition by the International Diabetes Federation (IDF) is universally considered as the most acceptable definition. The IDF definition revolves around 4 core components: obesity, dyslipidemia, hypertension, and diabetes mellitus. Several hypotheses have been proposed to explain the pathophysiology of urolithiasis resulting from metabolic syndrome, amongst which are the insulin resistance and Randall's plaque hypothesis. Similarly the pathophysiology of calcium and uric acid stone formation has been investigated to determine a connection between the two conditions. Studies have found many factors contributing to urolithiasis in patients suffering from metabolic syndrome, out of which obesity, overweight, and sedentary lifestyles have been identified as major etiological factors. Primary and secondary prevention methods therefore tend to revolve mainly around lifestyle improvements, including dietary and other preventive measures. PMID:25873954

    To extend nursing knowledge of distress experienced by family caregivers of children with rare genetic disorders, by exploring the perspectives of caregivers of children with Russell-Silver Syndrome in Taiwan. Caring for a child with a rare genetic disorder often has profound effects on families, especially when diagnosis and treatment is complex or not yet well developed, such as that in Russell-Silver Syndrome (or Silver-Russell syndrome). This disorder causes dwarfism and developmental difficulties, requiring long-term care planning. Previous research has focused mostly on medical care, but little is known about families' perspectives of caring difficulties, the help they need and nursing care required. An exploratory qualitative approach was used to inform this study. Family caregivers, whose children were undergoing medical care in a leading Taiwan medical centre, were invited to participate in face-to-face, in-depth interviews. Data were analysed by content analysis. Fifteen caregivers including 11 mothers, two fathers and two grandmothers participated. Five major themes and 13 sub-themes of care-giving distress were identified: endless psychological worries; the lengthy process to confirm a medical diagnosis; adjustment efforts in modifying family roles; dilemmas in deciding between Western or Chinese traditional medicine; and negative responses to society's concerns. Their primary sources of support were spouses, parents and health professionals, accordingly. Complex physio-psycho-social and decision-making distress in caring for children with a rare genetic disorder were systematically revealed from the perspectives of ethnic-Chinese family caregivers. Long-term care plans for children with a rare genetic disorder such as Russell-Silver Syndrome need to focus on positive dynamic family interactions, life-stage development and family caregiver support. Research on care-giving in rare genetic disorders is also warranted across cultures and countries to

    The metabolic syndrome (MBS) is characterised by a clustering of cardiovascular and metabolic risk factors. This syndrome is now widely recognised as a distinct pathological entity, and it is receiving a great deal of attention in the medical literature but also in the lay press. Globally speaking, persons with MBS have a clustering of the following risk factors: [List: see text] MBS is associated with important cardio/cerebrovascular and metabolic risks. Prevention and treatment are therefore of great importance. Preventive measures involving lifestyle are mandatory. In addition, MBS patients require pharmacological treatment, usually for the rest of their lives. Complex patterns of drug treatment will be required, since all the different, heterogenous pathophysiological problems will require appropriate treatment. After an introduction to MBS, this article provides an extensive and critical review of the drug treatment of this complex pathological entity. ImagesFigure 2 PMID:25696664

    The mineralocorticoid receptor (MR) mediates aldosterone effects on salt homeostasis and blood pressure regulation. MR activation also promotes inflammation, cardiovascular remodelling and endothelial dysfunction, and affects adipose tissue differentiation and function. Some of these effects derive from MR activation by glucocorticoids. Recent epidemiological studies show that the incidence of metabolic syndrome increases across quartiles of aldosterone, implicating the MR as a central player in metabolic homeostasis, involving electrolyte, water and energy balance. This review summarizes the current understanding of MR-mediated effects in diverse tissues and the role of aldosterone as a cardiometabolic risk factor, and discusses the possible relationship between inappropriate MR activation (by both mineralocorticoids and glucocorticoids) and the development of metabolic syndrome.

  9. “Micromanaging” metabolic syndrome

    PubMed Central

    2011-01-01

    Metabolic diseases are characterized by the failure of regulatory genes or enzymes to effectively orchestrate specific pathways involved in the control of many biological processes. In addition to the classical regulators of metabolic homeostasis, recent discoveries have shown the remarkable role of small non-coding RNAs (microRNAs) in the post-transcriptional regulation of a number of genes, and their involvement in many pathological states, such as diabetes, atherosclerosis and cancer. Of note is microRNA-33 (miR-33), an intronic microRNA (miRNA) located within the sterol regulatory element-binding protein (SREBP) genes, one of the master regulators of cholesterol and fatty acid metabolism. We have recently shown that miR-33 regulates cholesterol efflux and high-density lipoprotein (HDL) formation, as well as fatty acid oxidation and insulin signaling. These results describe a model in which miR-33 works in concert with its host genes to ensure that the cell's metabolic state is balanced, thus highlighting the clinical potential of miRNAs as novel therapeutic targets for treating cardiometabolic diseases.

    The role of the metabolic syndrome in the etiology of esophageal and gastric cancer is unclear. This was a large nationwide cohort study based on data from 11 prospective population-based cohorts in Norway with long-term follow-up, the Cohort of Norway (CONOR) and the third Nord-Trøndelag Health Study (HUNT3). The metabolic syndrome was assessed by objective anthropometric and metabolic biochemical measures and was defined by the presence of at least three of the following five factors: increased waist circumference, elevated triglycerides, low high-density lipoprotein cholesterol, hypertension and high glucose. Newly diagnosed cases of esophageal adenocarcinoma, esophageal squamous-cell carcinoma and gastric adenocarcinoma were identified from the Norwegian Cancer Registry. Hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated using Cox proportional hazard models with adjustment for potential confounders. Among 192,903 participants followed up for an average of 10.6 years, 62 developed esophageal adenocarcinoma, 64 had esophageal squamous-cell carcinoma and 373 had gastric adenocarcinoma. The metabolic syndrome was significantly associated with an increased risk of gastric adenocarcinoma (HR 1.44, 95% CI 1.14-1.82), but not associated with esophageal adenocarcinoma (HR 1.32, 95% CI 0.77-2.26) or esophageal squamous-cell carcinoma (HR 1.08, 95% CI 0.64-1.83). Increased waist circumference was associated with an increased HR of esophageal adenocarcinoma (HR 2.48, 95% CI 1.27-4.85). No significant association was found between any single component of the metabolic syndrome and risk of esophageal squamous-cell carcinoma. High waist circumference (HR 1.71, 95% CI 1.05-2.80), hypertension (HR 2.41, 95% CI 1.44-4.03) and non-fasting glucose (HR 1.74, 95% CI 1.18-2.56) were also related to an increased risk of gastric adenocarcinoma in women, but not in men.

    Peripheral neuropathy is a common problem encountered by neurologists and primary care physicians. While there are many causes for peripheral neuropathy, none can be identified in a large percentage of patients ("idiopathic neuropathy"). Despite its high prevalence, idiopathic neuropathy is poorly studied and understood. There is evolving evidence that impaired glucose tolerance (prediabetes) is associated with idiopathic neuropathy. Preliminary data from a multicenter study of diet and exercise in prediabetes (the Impaired Glucose Tolerance Neuropathy Study) suggests a diet and exercise counseling regimen based on the Diabetes Prevention Program results in improved metabolic measures and small fiber function. Prediabetes is part of the Metabolic Syndrome, which also includes hypertension, hyperlipidemia and obesity. Individual aspects of the Metabolic Syndrome influence risk and progression of diabetic neuropathy and may play a causative role in neuropathy both for those with prediabetes, and those with otherwise idiopathic neuropathy. Thus, a multifactorial treatment approach to individual components of Metabolic Syndrome may slow prediabetic neuropathy progression or result in improvement.

    Metabolic syndrome represents a clustering of risk factors related to an elevated risk of cardiovascular disease and type 2 diabetes. Occurrence of both metabolic syndrome and diabetes and their vascular complications share several pathogenetic features including subclinical, low-grade inflammation, altered oxidative/antioxidant status, and persistent platelet activation. Despite the availability of multiple interventions to counteract these metabolic changes, including appropriate diet, regular exercise, weight control and drugs, epidemiological data are witnessing the growing trend of the problem, reflecting both the multifactorial nature of these diseases as well as the scarce compliance of patients to established strategies. Several nutraceuticals used in clinical practice have been shown to target the pathogenesis of diabetes mellitus, metabolic syndrome and their complications and to favorably modulate a number of biochemical and clinical endpoints. These compounds include antioxidant vitamins, such as vitamins C and E, flavonoids, vitamin D, conjugated linoleic acid, omega-3 fatty acids, minerals such as chromium and magnesium, alpha-lipoic acid, phytoestrogens, and dietary fibers. Several areas of concern exist regarding the use of dietary supplements and nutraceuticals in this setting, including product standardization, definition of optimal dosing regimen, potential side effects, drug interactions, and need for evidence-based indications.

    Abstract The combination of metabolic syndrome and obstructive sleep apnea (OSA) has been termed “syndrome Z.” The prevalence of both OSA and metabolic syndrome is increasing worldwide, in part linked to the epidemic of obesity. Beyond their epidemiologic relationship, growing evidence suggests that OSA may be causally related to metabolic syndrome. We are only beginning to understand the potential mechanisms underlying the OSA–metabolic syndrome interaction. Although there is no clear consensus, there is growing evidence that alterations in the hypothalamic–pituitary axis, generation of reactive oxygen species (ROS) due to repetitive hypoxia, inflammation, and generation of adipokines may be implicated in the changes associated with both OSA and metabolic syndrome. Whether some or all of these metabolic alterations mechanistically link OSA to metabolic syndrome remains to be proven, but it is an area of intense scientific interest. PMID:19344228

    Metabolic syndrome (MS) is a cluster of metabolic disorders that collectively increase the risk of cardiovascular disease. Nitric oxide (NO) plays a crucial role in the pathogeneses of MS components and is involved in different mitochondrial signaling pathways that control respiration and apoptosis. The present review summarizes the recent information regarding the interrelations of mitochondria and NO in MS. Changes in the activities of different NO synthase isoforms lead to the formation of metabolic disorders and therefore are highlighted here. Reduced endothelial NOS activity and NO bioavailability, as the main factors underlying the endothelial dysfunction that occurs in MS, are discussed in this review in relation to mitochondrial dysfunction. We also focus on potential therapeutic strategies involving NO signaling pathways that can be used to treat patients with metabolic disorders associated with mitochondrial dysfunction. The article may help researchers develop new approaches for the diagnosis, prevention and treatment of MS. PMID:25741283

    Background: Metabolic syndrome is commonly associated with cardiovascular diseases and psychiatric mental illness. Hence, we aimed to assess the metabolic syndrome among severe mental illness (SMI). Materials and Methods: The study included 267 patients who were referred to the psychiatric unit at 5th Azar Education Hospital of Golestan University of Medical Sciences in Gorgan, Iran. Results: The mean waist circumference, systolic and diastolic blood pressure, triglyceride and fasting blood glucose levels were significantly higher in the SMI with metabolic syndrome, but the high density lipoprotein (HDL)-cholesterol was significantly lower. The prevalence of metabolic syndrome in SMI patients was 20.60%. There were significant differences in the mean of waist circumference, systolic (except for women) and diastolic blood pressure, triglyceride, HDL-cholesterol and fasting blood glucose in men and women with metabolic syndrome when compared with subjects without metabolic syndrome. The prevalence of metabolic syndrome in SMI women was higher than men. The most age distribution was in range of 30-39 years old. The most prevalence of metabolic syndrome was in age groups 50-59 years old. The prevalence of metabolic syndrome was increased from 30 to 59 years old. Conclusion: The prevalence of metabolic syndrome in patients with SMI in Gorgan is almost similar to those observed in Asian countries. The prevalence of metabolic syndrome was lower than western countries. These observations may be due to cultural differences in the region. It should be mention that the families of mental illness subjects in our country believe that their patients must be cared better than people without mental illness. These findings of this study suggest that mental illness patients are at risk of metabolic syndrome. According to our results, risk factors such as age and gender differences may play an important role in the presence of metabolic syndrome. In our country, women do less

    The aims of this study were to document sleep disturbances in individuals with Phelan-McDermid syndrome (PMS), to assess whether these individuals had been evaluated for sleep disorders, and to examine relationships between the sleep behavior of these individuals and the sleep behavior and daytime functioning of their caregivers. Participants were 193 caregivers of individuals with PMS recruited by the Phelan-McDermid Syndrome Foundation. Data were collected through a survey comprising 2 questionnaires: the Children's Sleep Habits Questionnaire (CSHQ) and the Parents' Sleep Habits Questionnaire. Data were analyzed using multiple linear regression analyses, Pearson correlation analyses, and independent-samples t-tests. Ninety percent of individuals with PMS showed evidence of marked sleep disturbance based on caregiver responses to the CSHQ. However, only 22% of individuals had undergone a formal sleep assessment. Reported increased sleep disturbance in individuals with PMS was a statistically significant predictor of reported increased sleep disturbance and daytime sleepiness in their caregivers. Sleep disturbance may be present in a substantial proportion of individuals with PMS and is negatively associated with caregivers' well-being. However, most individuals with PMS have not been evaluated for sleep disorders. When properly diagnosed, many sleep disorders can be alleviated with intervention. Thus, routine screening for and evaluation of sleep disturbances in individuals with PMS may have long-term positive impacts on the well-being of these individuals and their caregivers.

  17. Association between polycystic ovary syndrome and metabolic syndrome.

    Polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder affecting women in reproductive age. Although the etiology of PCOS remains unclear, it is believed to result from genetic, environmental and behavioral interactions. Women with PCOS have higher lifetime risk for cardiovascular disease (CVR) than healthy women at the same age and tend to display insulin resistance (IR). IR has traditionally been defined as a decreased ability of insulin to mediate the metabolic actions on glucose uptake, glucose production, and/or lipolysis. This results in a requirement for increased amounts of insulin to achieve a given metabolic action. Metabolic syndrome (MS) includes hyperinsulinemia, dyslipidemia, increased CVR and hyperleptinemia and metabolic disorders such as hypertension, IR, gestational diabetes, type 2 diabetes mellitus, systemic inflammation and endothelial dysfunction. The prevalence of MS in women is around 50 %. In addition, it has been recently suggested that women with MS show increased circulating androgens. The present review discusses the main alterations and features of PCOS and MS and the most important treatments.

    The metabolic syndrome is a cluster of common pathologies: abdominal obesity linked to an excess of visceral fat, insulin resistance, dyslipidemia and hypertension. At the molecular level, metabolic syndrome is accompanied not only by dysregulation in the expression of adipokines (cytokines and chemokines), but also by alterations in levels of leptin, a peptide hormone released by white adipose tissue. These changes modulate immune response and inflammation that lead to alterations in the hypothalamic 'bodyweight/appetite/satiety set point,' resulting in the initiation and development of metabolic syndrome. Metabolic syndrome is a risk factor for neurological disorders such as stroke, depression and Alzheimer's disease. The molecular mechanism underlying the mirror relationship between metabolic syndrome and neurological disorders is not fully understood. However, it is becoming increasingly evident that all cellular and biochemical alterations observed in metabolic syndrome like impairment of endothelial cell function, abnormality in essential fatty acid metabolism and alterations in lipid mediators along with abnormal insulin/leptin signaling may represent a pathological bridge between metabolic syndrome and neurological disorders such as stroke, Alzheimer's disease and depression. The purpose of this review is not only to describe the involvement of brain in the pathogenesis of metabolic syndrome, but also to link the pathogenesis of metabolic syndrome with neurochemical changes in stroke, Alzheimer's disease and depression to a wider audience of neuroscientists with the hope that this discussion will initiate more studies on the relationship between metabolic syndrome and neurological disorders.

    Testosterone deficiency in adult age is associated with a decrease in libido, energy, hematocrit, muscle mass and bone mineral density, as well as with depression. More recently, testosterone deficiency has also been associated with various components of the metabolic syndrome, which in turn is associated with a five-fold increase in the risk of cardiovascular disease. Low testosterone levels are associated with increased insulin resistance, increase in fat mass, low HDL cholesterol, higher triglyceride levels and hypertension. Testosterone replacement therapy in patients with testosterone deficiency and type 2 diabetes mellitus and/or metabolic syndrome has shown reductions in insulin resistance, total cholesterol, LDL cholesterol and triglycerides and improvement in glycemic control and anthropometric parameters.

    Metabolic syndrome is a clustering of symptoms associated with abdominal obesity that demonstrates a high risk for cardiovascular disease and type II diabetes mellitus. To evaluate football linemen in National Collegiate Athletic Association Divisions I, II, and III schools for the presence of metabolic syndrome according to the American Heart Association/National Heart, Lung, and Blood Institute criteria as well as to document other related biomarkers. Cross-sectional descriptive study. Three university locations on the first full day of football camp in early morning. Of 76 football linemen, 70 were able to provide blood samples. Height, mass, blood pressure, upper-body skinfolds, and waist circumference were measured at various stations. Two small venous samples of blood were collected and analyzed in a hospital laboratory for fasting insulin, glucose, high-density lipoprotein, total cholesterol, triglycerides, C-reactive protein, and glycosylated hemoglobin. The last station was a verbal family history for cardiovascular disease and diabetes; also, athletes filled out a nutrition attitudes questionnaire. Of the 70 athletes, 34 were identified as having metabolic syndrome according to measures of blood pressure, waist circumference, fasting glucose, high-density lipoprotein, and triglycerides. The mean total cholesterol-to-high-density lipoprotein cholesterol ratio for the group was 4.95, with 32 participants displaying values higher than 5.0. Twelve volunteers had total cholesterol levels greater than 200 mmol/L, 15 had high levels of C-reactive protein, and 9 had slightly elevated levels of glycosylated hemoglobin. Although athletes might be assumed to be protected from risks of cardiovascular disease, we found a high incidence of metabolic syndrome and other associated adverse biomarkers for heart disease in collegiate football linemen. Early screening, awareness, and intervention may have favorable effects on the overall health outcomes of football linemen.

  1. Cardiac NO signalling in the metabolic syndrome

    It is well documented that metabolic syndrome (i.e. a group of risk factors, such as abdominal obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides and low cholesterol level in high-density lipoprotein), which raises the risk for heart disease and diabetes, is associated with increased reactive oxygen and nitrogen species (ROS/RNS) generation. ROS/RNS can modulate cardiac NO signalling and trigger various adaptive changes in NOS and antioxidant enzyme expressions/activities. While initially these changes may represent protective mechanisms in metabolic syndrome, later with more prolonged oxidative, nitrosative and nitrative stress, these are often exhausted, eventually favouring myocardial RNS generation and decreased NO bioavailability. The increased oxidative and nitrative stress also impairs the NO-soluble guanylate cyclase (sGC) signalling pathway, limiting the ability of NO to exert its fundamental signalling roles in the heart. Enhanced ROS/RNS generation in the presence of risk factors also facilitates activation of redox-dependent transcriptional factors such as NF-κB, promoting myocardial expression of various pro-inflammatory mediators, and eventually the development of cardiac dysfunction and remodelling. While the dysregulation of NO signalling may interfere with the therapeutic efficacy of conventional drugs used in the management of metabolic syndrome, the modulation of NO signalling may also be responsible for the therapeutic benefits of already proven or recently developed treatment approaches, such as ACE inhibitors, certain β-blockers, and sGC activators. Better understanding of the above-mentioned pathological processes may ultimately lead to more successful therapeutic approaches to overcome metabolic syndrome and its pathological consequences in cardiac NO signalling.

    2008-12-01

    The metabolic syndrome is an important risk factor for type 2 diabetes mellitus and CVD. Epidemiological studies have now suggested protective effects of dairy product consumption on the development of this syndrome. Here we review the physiological effects and possible mechanisms involved of three main dairy constituents (Ca, protein, fat) on important components of the metabolic syndrome. Ca supplements improve the serum lipoprotein profile, particularly by decreasing serum total and LDL-cholesterol concentrations. They also lower systolic and diastolic blood pressure. Insufficient evidence exists for a significant role of Ca supplements or dairy in body-weight management. Effects of Ca may be related to intestinal binding to fatty acids or bile acids, or to changes in intracellular Ca metabolism by suppressing calciotropic hormones. Dietary proteins may increase satiety in both the short and longer term, which may result in a reduced energy intake. They have also been reported to improve the serum lipoprotein profile as compared with carbohydrates. Dairy proteins are precursors of angiotensin-I-converting enzyme-inhibitory peptides, which may lower blood pressure. Such effects, however, have inconsistently been reported in human studies. Finally, conjugated linoleic acid, which effectively lowers body weight in animals, has no such effect in humans in the quantities provided by dairy products. To reduce the intake of SFA, the consumption of low-fat instead of high-fat dairy products is recommended. In conclusion, more research is warranted to better understand the physiological effects and the mechanisms involved of dairy products in the prevention and treatment of the metabolic syndrome.

    2008-03-01

    Metabolic syndrome represents a constellation of risk factors associated with increased incidence of cardiovascular disease and progression to diabetes mellitus. Insulin resistance, a state of decreased biologic response to physiologic concentrations of insulin, is a key component of this syndrome and seems to be the result of a primary defect at the skeletal muscle glucose transporter. Acute illness and the perioperative period are characterized by a state of insulin resistance that manifests as hyperglycemia and leads to various other metabolic and biochemical alterations that adversely affect end organ function. Hyperglycemia in acutely ill patients adversely affects outcome. Achieving euglycemia seems beneficial in certain clinical situations, but considerable disagreement exists regarding the target blood sugar levels, the duration of therapy, and the modality. Pharmacotherapy, exercise, and nutrition to improve insulin sensitivity seem promising but require further evaluation to confirm their efficacy for perioperative risk reduction. This review discusses the pathophysiology and the clinical implications of metabolic syndrome and insulin resistance in the acutely ill patient with an emphasis on perioperative modulation strategies.

    The nutritional approach in the treatment of metabolic syndrome is a fundamental factor. It is important to raise awareness to patients about the benefits of following the treatments when you want to promote changes in lifestyle. The aim of this study was to assess nutritional adequacy in subjects with metabolic syndrome according to the dietary recommendations prescribed. Quasi-experimental research with 72 subjects with metabolic syndrome, held in southern Brazil. A nutritional orientation was conducted, related or not with physical exercise for three months. A 24-hour recall and two-day food record, were the reference method of dietary intake assessment. Nutritional adequacy was determined by the energy and nutrient intakes as defined by the Brazilian Food Guide Pyramid groups. Volunteers reached on average 80% of the energy consumption recommended. Protein and lipid intake was higher, and carbohydrate consumption was lower than recommended levels. There was a low intake of cereals, vegetables, dairy product and beans (p<0.001) as compared with the recommended servings. A high consumption of meat (p<0.001) and an adequate intake of fruit (p=0.149) were observed. The dietary intake was insufficient to meet the recommendation of energy, although the goal for weight loss was achieved. Still, the results show the need for a balance in food intake and quality of the diet to achieve nutritional adequacy. Copyright AULA MEDICA EDICIONES 2014. Published by AULA MEDICA.

    2016-01-01

    Metabolic Syndrome is a cluster of risk factors which often includes central obesity, dyslipidemia, insulin resistance, glucose intolerance, hypertension, endothelial dysfunction, as well as a pro-inflammatory, pro-oxidant, and pro-thrombotic environment. This leads to a dramatically increased risk of developing type II diabetes mellitus and cardiovascular disease, which is the leading cause of death both in the United States and worldwide. Increasing evidence suggests that berry fruit consumption has a significant potential in the prevention and treatment of most risk factors associated with Metabolic Syndrome and its cardiovascular complications in the human population. This is likely due to the presence of polyphenols with known antioxidant and anti-inflammatory effects, such as anthocyanins and/or phenolic acids. The present review summarizes the findings of recent dietary interventions with berry fruits on human subjects with or at risk of Metabolic Syndrome. It also discusses the potential role of berries as part of a dietary strategy which could greatly reduce the need for pharmacotherapy, associated with potentially deleterious side effects and constituting a considerable financial burden.

    The collection of impaired glucose metabolism, central obesity, elevated blood pressure, and dyslipidemia is identified as metabolic syndrome (MetS). It is estimated that approximately 25% of the world's population has MetS. In the United States, MetS is more common in men and Hispanics, and its incidence increases with age. Metabolic syndrome increases the risk of developing cardiovascular disease and type 2 diabetes mellitus. The underlying risk factors include insulin resistance and abdominal obesity. Confusion about MetS exists in part due to the lack of a consensus definition and treatment protocol. Treatment of MetS begins with therapeutic lifestyle changes and then pharmacologic treatment of the syndrome's individual components. Effective interventions include diet modification, exercise, and use of pharmacologic agents to treat risk factors. Weight loss and increasing physical activity significantly improve all aspects of MetS. A diet that includes more fruits, vegetables, whole grains, monounsaturated fats, and low-fat dairy products will benefit most patients with MetS. Physicians can be most effective in advising patients by customizing specific lifestyle recommendations after assessing patients for the presence of risk factors.

    This was a two-stage cross-sectional study that assessed metabolic syndrome and associated factors among prepubertal schoolchildren. In the first stage, nutritional status, blood pressure, personal (low birth weight) and family antecedents for cardiovascular disease (CVD) were collected. In the second stage, schoolchildren with at least one of these criteria participated: obesity, personal or family history. Metabolic syndrome (MS) was defined by ATP III and WHO definitions. Among 929 (6-10 year old) schoolchildren, 27.7% presented with overweight/obesity, 12.2% hypertension, and personal (9.4%) and family (35.3%) antecedents. 205 children finished the second stage. The frequencies of MS-ATP and MS-WHO were 9.3% and 1.9%. Among the obese, MS was present in 25.8% (ATP) and 5.2% (WHO). Children with normal weight presented: low HDL (23.6%), hyperglycaemia (3.6%), HOMA-IR (0.9%) and MS-ATP (0.9%). In conclusion, overweight/obesity was associated with metabolic syndrome in schoolchildren. It was found that children with normal weight with personal and/or family antecedents presented with HOMA-IR and MS-ATP.

    Bovine Marfan syndrome is a disorder that closely resembles human Marfan syndrome in its clinical signs and pathological lesions. The similarities between the human and bovine diseases suggest that similar metabolic defects could be responsible. Although indirect immunofluorescent assays for fibrillin in skin biopsies did not distinguish affected cattle from control animals, cultures of skin fibroblasts of affected animals were distinguished from normal, unrelated control animals and normal half-siblings on the basis of fibrillin staining. After 72 to 96 hours in culture, stained with anti-fibrillin monoclonal antibody 201, hyperconfluent fibroblast cultures of affected cattle had less immunoreactive fibrillin than control cultures, and the staining pattern was granular rather than fibrillar. Under similar culture conditions, normal bovine aortic smooth muscle cells produced large amounts of immunoreactive fibrillin, but smooth muscle cells from a single affected cow showed markedly less fibrillin staining. In pulse-chase metabolic labeling experiments with [35S]cysteine, dermal fibroblasts from 6 affected calves, incorporated far less fibrillin into the extracellular matrix than control cells. These findings are similar to those reported in human Marfan syndrome, and they suggest that the bovine Marfan syndrome, like the human disorder, is caused by a mutation in fibrillin, leading to defective microfibrillar synthesis.

    Background The prevalence of metabolic syndrome in COPD patients and its impact on patient related outcomes has been little studied. We evaluated the prevalence of metabolic syndrome and clinical and functional characteristics in patients with COPD and healthy subjects. Methods 228 COPD patients and 156 healthy subjects were included. Metabolic syndrome was defined using criteria of the IDF. In all patients spirometry, body composition, functional exercise performance, and mood and health status were assessed. Groups were stratified for BMI and gender. Results Metabolic syndrome was present in 57% of the COPD patients and 40% of the healthy subjects. After stratification for BMI, presence of metabolic syndrome in patients with a BMI ≥25 kg/m2 was higher than in healthy peers. Patients with metabolic syndrome and a BMI <25 kg/m2 had higher BMI, fat free mass index and bone mineral density, and a lower 6MWD than the BMI matched patients without metabolic syndrome. Spirometry, maximal ergometry, mood and health status, and blood gases were not different between those groups. In COPD patients with metabolic syndrome self-reported co-morbidities and medication use were higher than in those without. Conclusion Metabolic syndrome is more prevalent in overweight or obese COPD patients than in BMI matched healthy subjects. Metabolic syndrome did not additionally impact patients' functional outcomes, but did impact the prevalence of co-morbidities. PMID:24950070

    Smith-Magenis syndrome (SMS) is a complex disorder characterized by numerous challenges, including intellectual disability, speech delay, decreased pain sensitivity, sleep disturbances, hyperactivity, mood instability, and self-injury. Caregivers must readily adapt to the ever-changing needs of the child. Due to these demands, caregivers may encounter difficulties maintaining their own level of well-being. Thus, a total of 112 primary caregivers (i.e., parents) of individuals diagnosed with SMS responded to online questionnaires to assess demographic and psychosocial factors, such as perceptions of child health vulnerability, benefit finding, sleep behaviors, anxiety and depression symptomatology, and caregiver satisfaction and self-efficacy, which may be related to caregiver well-being. Results show that, among mothers, caregiver well-being was directly related to perceived child health vulnerability, caregiver satisfaction, and benefit finding, and a significant moderating effect was observed for depression/anxiety counseling after beginning the caregiver role on the relationship between anxiety symptomatology and caregiver well-being. Results further suggest that maternal caregivers who report high levels of anxiety but do not seek counseling fair the worst in terms of well-being. Among fathers, lower depression symptoms and greater benefit finding were related to higher levels of caregiver well-being. These data show that many factors play roles in influencing coping and well-being among SMS caregivers. Investigating these variables and relationships may reveal additional resources and interventions to assist primary caregivers.

    In late twentieth century, Ruderman and Reaven showed that insulin resistance might be fundamental to metabolic syndrome (MetS) which means a constellation of obesity-related metabolic derangements predisposing to type 2 diabetes and cardiovascular disease. In 2001, user-friendly National Cholesterol Education Program (NCEP) criteria of MetS were proposed. In 2005, the International Diabetes Federation (IDF) and the Examination Committee for Criteria of Metabolic Syndrome in Japan issued different criteria of MetS where abdominal obesity is a necessary component. In 2009, IDF, National Heart, Lung, and Blood Institute, American Heart Association, World Heart Federation, International Atherosclerosis Society, and International Association for the Study of Obesity jointly adopted the revised NCEP criteria, where abdominal obesity is not a necessary component, as worldwide criteria of MetS. In 2010, WHO Expert Consultation warned that MetS is a concept that focuses attention on complex multifactorial health problems but has limited practical utility as a management tool. In animal studies, adipose tissue inflammation characterized by an increased number of crown-like structures in adipose tissue, rather than obesity per se, was shown to be a fundamental mechanism of metabolic derangements.

  13. Leg cramps in relation to metabolic syndrome.

    A leg cramp is a pain that comes from a leg muscle. It is due to a muscle spasm which usually occurs in a calf muscle, below and behind a knee. Leg cramps (often called night cramps) usually occur most commonly at night when in bed. Night leg cramps are involuntary painful contractions of skeletal muscles arose in the calves and soles of the feet. Although in most cases they aren't harmful and resolve easily in some instances they have a long duration and can result in intense pain, disturb normal sleep and make a person feel anxious. Pathophysiology of leg cramps is poorly understood. The aim of our study was to determine the role of metabolic syndrome in relation to night leg cramps. The study included 86 subjects aged 34 to 88 years. Metabolic syndrome group consisted of 40 subjects (10 men (25%) and 30 women (75%)); the control group consisted of 46 persons (9 men (19.5%) and 37 women (80.5%)). According to frequency and intensity of manifestation leg cramps were subdivided into less frequent and frequent leg cramps. Blood samples were analysed for lipids, fasting glucose, red blood cells and electrolytes. Persons were screened for leg vein insufficiency as well. The investigation showed that 77.5% (31/40) of patients with metabolic syndrome had leg cramps, from which 60% (24/40) had frequent leg cramps. In control group 73.9% (34/46) had leg cramps, from which 50% (23/46) had frequent leg cramps. Among known predisposing factors leg cramps most often were associated with deep vein insufficiency and superficial vein varicose. High frequency of night leg cramps in our study is due to female predominance (75% versus 25% women and men, respectively) and age distribution in our study population (from 34 to 88 years old). The investigation showed that people often experience nocturnal leg cramps. Leg cramp is slightly increasing among the patients with metabolic syndrome. Frequent leg cramps were observed in 60% of cases in metabolic syndrome group versus 50% of

    Bile acids are increasingly recognized as key regulators of systemic metabolism. While bile acids have long been known to play important and direct roles in nutrient absorption, bile acids also serve as signaling molecules. Bile acid interactions with the nuclear hormone receptor farnesoid X receptor (FXR) and the membrane receptor G-protein-coupled bile acid receptor 5 (TGR5) can regulate incretin hormone and fibroblast growth factor 19 (FGF19) secretion, cholesterol metabolism, and systemic energy expenditure. Bile acid levels and distribution are altered in type 2 diabetes and increased following bariatric procedures, in parallel with reduced body weight and improved insulin sensitivity and glycemic control. Thus, modulation of bile acid levels and signaling, using bile acid binding resins, TGR5 agonists, and FXR agonists, may serve as a potent therapeutic approach for the treatment of obesity, type 2 diabetes, and other components of the metabolic syndrome in humans.

    Increasing prevalence of exogenous obesity in children appears possibly related to changes in their lipid and carbohydrate metabolism resulting from insulin resistance which, together with obesity and arterial hypertension, are among the components of metabolic syndrome. The aim of this study was to evaluate the age related incidence of obesity complications and the prevalence of metabolic syndrome in children according to the latest criteria. A total of 98 obese children were divided in two age groups (5 to 10 and 10 to 16 years). In all patients the BMI was calculated, standard deviation score of BMI (SDS BMI) was estimated according to the data by anthropometric surveys Slovakia and obesity was defined as SDS BMI >2 which is equal to 97th percentile for the appropriate age and gender. Blood pressure >95th percentile for the appropriate gender, age and body was classified as hypertension. Fasting glycemia, total and HDL cholesterol and triglycerides were determined in serum and oral glucose tolerance test was performed. Insulin resistance was classified according to HOMA index. Among 21 children less than 10 years of age lower HOMA values and no impaired glucose tolerance appeared, but hypercholesterolemia was found in 8 cases (38.1 %). Among 77 patients aged 10 to 16 years increased frequency of cases was found with insulin resistance (37.7 %), increased triglycerides (53.3 %), decreased HDL cholesterol (54.4 %) and impaired glucose tolerance (7.8 %). In this group 32.5 % of children showed metabolic syndrome based on modified IDF criteria, while such prevalence rose to 39.0 % if borderline criteria for blood pressure were used. The treatment of referred pathological states requires lifestyle changes and follow up at the specialized clinic.

    2014-01-01

    Lennox–Gastaut syndrome (LGS) has a major impact on the health-related quality of life (HRQL) of the affected children as well as their caregivers. The primary caregiver in the family is generally the mother, with support from the father and siblings. The burden of care and the effects of the disease on the child necessitate adjustments in virtually all aspects of the lives of their family. These adjustments inevitably affect the physical, emotional, social, and financial health of the whole family. Numerous sources of support for families can help to ease the burden of care. Improvements in the treatment of LGS, in addition to helping the child with LGS, would likely help improve the HRQL of the family members. This pilot parent survey was designed to explore the impact of epilepsy on caregiver HRQL. Parents of children with epilepsy who had contacted the Epilepsy Information Service at the Wake Forest University School of Medicine, Winston-Salem, NC, USA, were sent questionnaires comprising open- and closed-ended questions. A total of 200 surveys were distributed, with a return rate of 48%. The results revealed that 74% of the parents believed that having a child with epilepsy brought them and their partner closer together. However, when the parents were asked to explain the manner in which epilepsy affected their families, answers included continuous stress, major financial distress, and lack of time to spend with other children. Information and resources for the families of children with LGS could help improve the HRQL of both the patients and their relatives. PMID:25336963

    The aim of the study was to elucidate specific features of chronic recurrent atrial fibrillation (AF) in patients with metabolic syndrome (MS) and disturbed carbohydrate metabolism compared with AF patients without MS. It enrolled 145 patients aged 44-83 years: 117 with abdominal obesity (BMI >30 kg/m2, waist circumference >80 and 94 cm in women and men respectively) including 30 without metabolic disturbances; 35 with impaired glucose tolerance (IGT), 52 with type 2 DM, and 28 controls without MS. Parameters measured included frequency and severity of AF, carbohydrate and lipid metabolism, albuminurea, C-reactive peptide level, quality of AH control, results of echocardiography and 24 hour ECG monitoring (sinus rhythm), and insulin resistance index (HOMA IRindex). Groups of AF and MS patients were dominated by women. The frequency and severity of AF relapses in MS patients were higher than in controls (especially in the presence of IGT and DM). IGT and DM2 associated with structural changes in myocardium (left atrial dilatation, prevalence of LV concentric hypertrophy, diastolic dysfunction) coupled to higher systolic AH and marked metabolic disorders (hyperglycemia, IR, elevated microalbuminurea and C-reactive protein level, dyslipidemia). These conditions contribute to the frequency and severity of AF relapses. Development of AF in MS is a multifactor problem necessitating strict control of AH, dyslipidemia, DM2 and IGT, reduction of body weight and abdominal obesity.

Convenient instruments that do not require laboratory or physical investigation would be useful in early screening individuals at high risk of metabolic syndrome. Examination of the autonomic function can be taken as a directly reference and screening indicator for predicting metabolic syndrome. Methodology and Principal Findings The EZSCAN test, as an efficient and noninvasive technology, can access autonomic function through measuring electrochemical skin conductance. In this study, we used EZSCAN value to evaluate autonomic function and to detect metabolic syndrome in 5,887 participants aged 40 years or older. The EZSCAN test diagnostic accuracy was analyzed by receiver operating characteristic curves. Among the 5,815 participants in the final analysis, 2,541 were diagnosed as metabolic syndrome and the overall prevalence was 43.7%. Prevalence of the metabolic syndrome increased with the elevated EZSCAN risk level (p for trend <0.0001). Moreover, EZSCAN value was associated with an increase in the number of metabolic syndrome components (p for trend <0.0001). Compared with the no risk group (EZSCAN value 0–24), participants at the high risk group (EZSCAN value: 50–100) had a 2.35 fold increased risk of prevalent metabolic syndrome after the multiple adjustments. The area under the curve of the EZSCAN test was 0.62 (95% confidence interval [CI], 0.61–0.64) for predicting metabolic syndrome. The optimal operating point for the EZSCAN value to detect a high risk of prevalent metabolic syndrome was 30 in this study, while the sensitivity and specificity were 71.2% and 46.7%, respectively. Conclusions and Significance In conclusion, although less sensitive and accurate when compared with the clinical definition of metabolic syndrome, we found that the EZSCAN test is a good and simple screening technique for early predicting metabolic syndrome.

    Background: Sleep complaints are highly prevalent and associated with cardiovascular disease (CVD) morbidity and mortality. This is the first prospective study to report the association between commonly reported sleep symptoms and the development of the metabolic syndrome, a key CVD risk factor. Methods: Participants were from the community-based Heart Strategies Concentrating on Risk Evaluation study. The sample was comprised of 812 participants (36% African American; 67% female) who were free of metabolic syndrome at baseline, had completed a baseline sleep questionnaire, and had metabolic syndrome evaluated 3 years after baseline. Apnea-hypopnea index (AHI) was measured cross-sectionally using a portable monitor in a subset of 290 participants. Logistic regression examined the risk of developing metabolic syndrome and its components according to individual sleep symptoms and insomnia syndrome. Results: Specific symptoms of insomnia (difficulty falling asleep [DFA] and “unrefreshing” sleep), but not a syndromal definition of insomnia, were significant predictors of the development of metabolic syndrome. Loud snoring more than doubled the risk of developing the metabolic syndrome and also predicted specific metabolic abnormalities (hyperglycemia and low high-density lipoprotein cholesterol). With further adjustment for AHI or the number of metabolic abnormalities at baseline, loud snoring remained a significant predictor of metabolic syndrome, whereas DFA and unrefreshing sleep were reduced to marginal significance. Conclusion: Difficulty falling asleep, unrefreshing sleep, and, particularly, loud snoring, predicted the development of metabolic syndrome in community adults. Evaluating sleep symptoms can help identify individuals at risk for developing metabolic syndrome. Citation: Troxel WM; Buysse DJ; Matthews KA; Kip KE; Strollo PJ; Hall M; Drumheller O; Reis SE.

  1. Obesity, adipokines and metabolic syndrome in polycystic ovary syndrome.

    PubMed

    Carmina, Enrico

    2013-01-01

    The complex mechanisms linking fat excess to metabolic syndrome are not well understood, but several experimental studies have shown that altered production of adipokines plays a main role in development and progression of this disorder. In particular, reduced secretion of adiponectin has a crucial role in inducing insulin resistance but also in determining the clustering of elevated triglycerides and small, dense LDL particles. Increased leptin secretion may be responsible for sympathetic nervous system overactivity and hypertension, while reduced omentin may have an important permissive role in the development of atherogenic processes. Finally, cytokines and other adipokines (resistin, visfatin) determine and modulate the inflammatory process that is an essential component of this condition of cardiovascular risk. Because obesity is prevalent in polycystic ovary syndrome (PCOS), it is not surprising that patients with PCOS present altered adipokine levels and increased prevalence of metabolic syndrome. However, because of the presence of other CV risk factors (androgen excess), in PCOS adipokine dysfunction is particularly severe. Understanding and treating adipokine dysfunction in young women with PCOS is an essential component of any politics of prevention of CV diseases in the general population.

  2. Metabolic Syndrome: Nonalcoholic Fatty Liver Disease.

    PubMed

    Williams, Tracy

    2015-08-01

    Although nonalcoholic fatty liver disease (NAFLD) is not one of the defining criteria for metabolic syndrome, it is a common hepatic manifestation. NAFLD includes a spectrum of histologic findings ranging from simple steatosis, known as nonalcoholic fatty liver, to nonalcoholic steatohepatitis (NASH). To make the diagnosis of NAFLD, other etiologies of steatosis or hepatitis, such as hepatotoxic drugs, excessive alcohol intake, congenital errors of metabolism, or viral hepatitis, must be ruled out. After ruling out other conditions, the diagnosis of NAFLD often is made clinically, but a definitive diagnosis of NASH requires liver biopsy. As with other complications of metabolic syndrome, insulin resistance is thought to be an underlying etiology of NAFLD. Management strategies attempt to reverse or improve insulin resistance while minimizing liver damage. The strongest evidence supports lifestyle modifications with weight loss, but there is some evidence to support bariatric surgery, medical therapy with insulin-sensitizing agents, and/or pharmacotherapy to promote weight loss. Cardiovascular disease is the major cause of mortality in patients with NAFLD, so management must include modification of cardiovascular risk factors.

    Klinefelter syndrome (KS) is one of the most common genetic causes of male infertility. This condition is associated with much comorbidity and with a lower life expectancy. The aim of this review is to explore more in depth cardiovascular and metabolic disorders associated to KS. KS patients have an increased risk of cerebrovascular disease (standardized mortality ratio, SMR, 2.2; 95% confidence interval, CI, 1.6-3.0), but it is not clear whether the cause of the death is of thrombotic or hemorrhagic nature. Cardiovascular congenital anomalies (SMR, 7.3; 95% CI, 2.4-17.1) and the development of thrombosis or leg ulcers (SMR, 7.9; 95% CI, 2.9-17.2) are also more frequent in these subjects. Moreover, cardiovascular abnormalities may be at least partially reversed by testosterone replacement therapy (TRT). KS patients have also an increased probability of endocrine and/or metabolic disease, especially obesity, metabolic syndrome and type 2 diabetes mellitus. The effects of TRT on these abnormalities are not entirely clear.

  4. Metabolic syndrome and the hepatorenal reflex

    2016-01-01

    Insufficient hepatic O2 in animal and human studies has been shown to elicit a hepatorenal reflex in response to increased hepatic adenosine, resulting in the stimulation of renal as well as muscle sympathetic nerve activity and activating the renin angiotensin system. Low hepatic ATP, hyperuricemia, and hepatic lipid accumulation reported in metabolic syndrome (MetS) patients may reflect insufficient hepatic O2 delivery, potentially accounting for the sympathetic overdrive associated with MetS. This theoretical concept is supported by experimental results in animals fed a high fructose diet to induce MetS. Hepatic fructose metabolism rapidly consumes ATP resulting in increased adenosine production and hyperuricemia as well as elevated renin release and sympathetic activity. This review makes the case for the hepatorenal reflex causing sympathetic overdrive and metabolic syndrome in response to exaggerated splanchnic oxygen consumption from excessive eating. This is strongly reinforced by the fact that MetS is cured in a matter of days in a significant percentage of patients by diet, bariatric surgery, or endoluminal sleeve, all of which would decrease splanchnic oxygen demand by limiting nutrient contact with the mucosa and reducing the nutrient load due to loss of appetite or dietary restriction.

    Obesity is fast becoming a bane for the present civilization, as a result of sedentary lifestyle, atherogenic diet, and a susceptible thrifty genotype. The concept of metabolic syndrome, which is a constellation of metabolic disturbances, has crystallized over the last 80 years with the aim of identifying those at greater risk of developing type 2 diabetes and cardiovascular disease. These patients have visceral obesity and insulin resistance characterized by hypertyriglyceridemia. Recently, it has been realized that they are also at an increased risk of chronic renal disease. Release of adipocytokines leads to endothelial dysfunction. There is also activation of systemic and local renin-angiotensin-aldosterone system, oxidative stress, and impaired fibrinolysis. This leads to glomerular hyperfiltration, proteinuria, focal segmental glomerulosclerosis (FSGS), and ultimately end-stage renal disease (ESRD). Treatment consists of lifestyle modifications along with optimal control of blood pressure, blood sugar and lipids. Metformin and thiazolidenidiones reduce insulin resistance; while angiotensin converting enzyme inhibitors and angiotensin receptor blockers reduce proteinuria and have a renoprotective effect. Exciting new medical therapies on the horizon include rimonabant a cannabinoid receptor type 1 antagonist, soy proteins, and peroxisome proliferator-activated receptor (PPAR) agonist. Bariatric surgery for morbid obesity has also been shown to be effective in treating metabolic syndrome.

    The number of childhood cancer survivors is increasing as survival rates improve. However, complications after treatment have not received much attention, particularly metabolic syndrome. Metabolic syndrome comprises central obesity, dyslipidemia, hypertension, and insulin resistance, and cancer survivors have higher risks of cardiovascular events compared with the general population. The mechanism by which cancer treatment induces metabolic syndrome is unclear. However, its pathophysiology can be categorized based on the cancer treatment type administered. Brain surgery or radiotherapy may induce metabolic syndrome by damaging the hypothalamic-pituitary axis, which may induce pituitary hormone deficiencies. Local therapy administered to particular endocrine organs directly damages the organs and causes hormone deficiencies, which induce obesity and dyslipidemia leading to metabolic syndrome. Chemotherapeutic agents interfere with cell generation and growth, damage the vascular endothelial cells, and increase the cardiovascular risk. Moreover, chemotherapeutic agents induce oxidative stress, which also induces metabolic syndrome. Physical inactivity caused by cancer treatment or the cancer itself, dietary restrictions, and the frequent use of antibiotics may also be risk factors for metabolic syndrome. Since childhood cancer survivors with metabolic syndrome have higher risks of cardiovascular events at an earlier age, early interventions should be considered. The optimal timing of interventions and drug use has not been established, but lifestyle modifications and exercise interventions that begin during cancer treatment might be beneficial and tailored education and interventions that account for individual patients' circumstances are needed. This review evaluates the recent literature that describes metabolic syndrome in cancer survivors, with a focus on its pathophysiology.

    Chronic kidney disease (CKD) is more likely to progress to end-stage renal disease (ESRD) in African Americans while the reasons for this are unclear. The metabolic syndrome is a risk factor for the development of diabetes, cardiovascular disease, and has been recently linked to incident CKD. Historically, fewer African Americans meet criteria for the definition of metabolic syndrome, despite having higher rates of cardiovascular mortality than Caucasians. The presence of microalbuminuria portends increased cardiovascular risks and has been shown to cluster with the metabolic syndrome. We recently reported that proteinuria is a predictor of CKD progression in African American hypertensives with metabolic syndrome. In this review we explore the potential value of including CKD markers--microalbuminuria/proteinuria or low glomerular filtration rate (GFR)-in refining the cluster of factors defined as metabolic syndrome, ie, "cardiorenal metabolic syndrome."

    Metabolic syndrome (Met S) is a clustering of risk factors comprising of abdominal obesity, dyslipidemia, elevated blood pressure, and abnormal glucose tolerance. The prevalence of Met S has been increasing in the last few years throughout the world. Psoriasis has consistently been associated with Met S as well as its various components. However, the association is no longer limited to psoriasis alone. Various dermatological conditions such as lichen planus, androgenetic alopecia, systemic lupus erythematosus, skin tags, acanthosis nigricans, and even cutaneous malignancies have also been found to be associated with this syndrome. Though chronic inflammation is thought to be the bridging link, the role of oxidative stress and endocrine abnormalities has recently been proposed in bringing them together. PMID:23919003

    Metabolic syndrome (MetS), a clustering of metabolic risk factors, identifies individuals at increased risk of diabetes and cardiovascular disease (CVD). Measurement of waist circumference, high-density lipoprotein-cholesterol, triglycerides, blood pressure and fasting blood glucose are easily obtained in the clinic. At any level of low-density lipoprotein-cholesterol, presence of MetS increases the risk of adverse CVD outcomes including bothatherosclerotic CVD and atrial fibrillation. The MetS construct should focus the clinician on recommending behavioral lifestyle modification as this improves all of its components. The challenge, however, has been the lack of a standardized approach to achieve effective and sustained lifestyle modification in clinical practice. We briefly review various approaches useful to the clinician in counseling such patients. These include group lifestyle programs and emerging mobile technology. Technology alone may not be sufficient, but as an adjunct has the promise to improve low rates of behavioral change currently seen with traditional programs.

    Circadian rhythms (approximately 24h) are widely characterized at molecular level and their generation is acknowledged to originate from oscillations in expression of several clock genes and from regulation of their protein products. While general entrainment of organisms to environmental light-dark cycles is mainly achieved through the master clock of the suprachiasmatic nucleus in mammals, this molecular clockwork is functional in several organs and tissues. Some studies have suggested that disruption of the circadian system (chronodisruption (CD)) may be causal for manifestations of the metabolic syndrome. This review summarizes (1) how molecular clocks coordinate metabolism and their specific role in the adipocyte; (2) the genetic aspects of and scientific evidence for obesity as a chronobiological illness; and (3) CD and its causes and pathological consequences. Finally, ideas about use of chronobiology for the treatment of obesity are discussed.

    Salivary amylase is a glucose-polymer cleavage enzyme that is produced by the salivary glands. It comprises a small portion of the total amylase excreted, which is mostly made by the pancreas. Amylases digest starch into smaller molecules, ultimately yielding maltose, which in turn is cleaved into two glucose molecules by maltase. Starch comprises a significant portion of the typical human diet for most nationalities. Given that salivary amylase is such a small portion of total amylase, it is unclear why it exists and whether it conveys an evolutionary advantage when ingesting starch. This review will consider the impact of salivary amylase on oral perception, nutrient signaling, anticipatory metabolic reflexes, blood sugar, and its clinical implications for preventing metabolic syndrome and obesity.

    Rett syndrome is a severe neurodevelopmental disorder associated with mutations in the MECP2 gene. Irregular breathing patterns and abdominal bloating are prominent but poorly understood features. Our aims were to characterize the abnormal breathing patterns and abdominal bloating, investigate the distribution of these by age and mutation type and examine their impact and management from a caregiver perspective. We invited previously recruited families from the International Rett Syndrome Study to complete a web-based questionnaire concerning their family member with Rett syndrome aged between 2 and 57 years. We used logistic regression to investigate presence, frequency and impact of breath-holding, hyperventilation, or abdominal bloating by age group and mutation type. Age of onset for both breathing abnormalities was investigated using time-to-onset analysis, and the Kaplan-Meier method was used to estimate the failure function for the study sample. Descriptive statistics were used to characterize the management of irregular breathing. Questionnaires were returned by 413/482 (85.7%) families. Breath-holding was reported for 68.8%, hyperventilation for 46.4% and abdominal bloating for 42.4%. Hyperventilation was more prevalent and frequent in those younger than 7 years of age and abdominal bloating in those aged over 20 years. Onset of breathing irregularities usually occurred during early childhood. Caregivers perceived that daily life was considerably impacted for almost half (44.1%) of those with abdominal bloating and in just over than a third of those with breath-holding (35.8%) or hyperventilation (35.1%). Although perceived impact was broadly comparable between age and mutation groups for breath-holding, hyperventilation and abdominal bloating, girls and women with a p.Arg294* mutation were considered to be more affected by all three conditions. Only 31 individuals had received medically prescribed treatments including 12 different medications, added

    1. Abstract Animal models have enriched understanding of the physiological basis of metabolic disorders and advanced identification of genetic risk factors underlying the metabolic syndrome (MetS). Murine models are especially appropriate for this type of research, and are an excellent resource not only for identifying candidate genomic regions, but also for illuminating the possible molecular mechanisms or pathways affected in individual components of MetS. In this review, we briefly discuss findings from mouse models of metabolic disorders, particularly in light of issues raised by the recent flood of human genome-wide association studies (GWAS) results. We describe how mouse models are revealing that genotype interacts with environment in important ways, indicating that the underlying genetics of MetS is highly context dependant. Further we show that epistasis, imprinting and maternal effects each contribute to the genetic architecture underlying variation in metabolic traits, and mouse models provide an opportunity to dissect these aspects of the genetic architecture that are difficult if not impossible to ascertain in humans. Finally we discuss how knowledge gained from mouse models can be used in conjunction with comparative genomic methods and bioinformatic resources to inform human MetS research. PMID:20088816

    The metabolic syndrome, a constellation of interrelated risk factors for cardiovascular disease and type 2 diabetes mellitus, has become a major public health concern against the backdrop of increasing rates of obesity. Insulin resistance plays a pivotal role as the underlying pathophysiological linchpin of the various components of the syndrome. The metabolic syndrome is well recognized in adults, and there is convincing evidence that it starts in childhood, with progressive clustering of the various components over time and tracking through adulthood. Adult women and adolescents with polycystic ovary syndrome (PCOS) have higher prevalence rates of the metabolic syndrome compared with the general population. Several anthropometric (obesity, particularly abdominal obesity), metabolic (insulin resistance/hyperinsulinemia, dyslipidemia) and hormonal (low IGFBP1, IGFBP2 and low sex hormone binding globulin) features of adolescents with PCOS are also features of the metabolic syndrome. Insulin resistance, believed to be a key pathogenic factor in both PCOS and the metabolic syndrome, may be the thread that links the two conditions. Menstrual health in adolescents could be viewed as yet another component in the evaluation of the metabolic syndrome. Careful assessment of menstrual history and appropriate laboratory work-up could reveal the presence of PCOS in obese at-risk adolescent girls with a family history of the metabolic syndrome.

    Cardiovascular disease represents a massive healthcare burden worldwide. Gender differences in the pathophysiology, presentation and prognosis of cardiovascular disease have been described in the literature. Metabolic syndrome, characterized by a cluster of metabolic abnormalities is associated with increased risk for type 2 diabetes mellitus and atherosclerotic cardiovascular disease. With the global obesity epidemic, the prevalence of metabolic syndrome is rising rapidly in the developed as well as developing world. However, there is considerable variation in the prevalence based on geography, age, sex and, definition used for diagnosis. Data on gender related differences in metabolic syndrome is relatively scarce. Here, we aim to review the gender differences in epidemiology and pathophysiology of metabolic syndrome as well as its individual components. Knowledge of gender differences in metabolic syndrome can help design gender specific preventative and therapeutic strategies that will have a positive impact on overall population health.

    The metabolic syndrome is featured by the combination of obesity induced by visceral fat accumulation, dyslipidemia, hyperglycemia, and hypertension. It is well documented that obesity and body weight increase are positively linked to increased bone mineral density (BMD) and reduced fracture risk of weight-bearing bones through mechanical stress. On the other hand, inflammatory cytokines secreted from visceral fat and advanced glycation products induced by hyperglycemia tend to reduce BMD and to increase fracture risk in contrast to obesity. Thus, BMD and fracture risk in patients with the metabolic syndrome may be determined by the balance between the beneficial effect of obesity and detrimental ones of inflammatory cytokines and hyperglycemia on bone.

    Persons with epilepsy have higher cardiovascular mortality and morbidity compared to general population and alteration of their biochemical milieu is one of the proposed mechanisms. We aimed to study the prevalence of metabolic syndrome and cardiovascular risk factors in young adults with epilepsy and the association with antiepileptic drug use. An observational study was conducted in persons with epilepsy aged 20-49 years using antiepileptic drugs regularly for the previous three years. The subjects were examined and their blood samples were collected for fasting blood glucose and lipid profile. Over 18 months, 183 patients (120 males; 63 females) were recruited (mean age 32.5 ± 8.9 years). Metabolic syndrome (MetS) by ATP III criteria was present in 54 (29.5%) subjects. People with MetS in our group had higher frequency of abdominal obesity (50.0%) and hypertriglyceridemia (55.5%) than diabetes/impaired fasting glucose (27.8%). Older age (p=0.005) and use of valproate (p=0.012) were associated with significant risk of MetS. Clinicians need to be vigilant regarding the risk of MetS while initiating treatment and following up persons with epilepsy. Copyright © 2016 British Epilepsy Association. Published by Elsevier Ltd.

    Metabolic syndrome, a cluster of risk factors for type 2 diabetes mellitus and cardiovascular disease, is becoming an increasing global health concern. Insulin resistance is often associated with metabolic syndrome and also typical hepatic manifestations such as nonalcoholic fatty liver disease. Profiling of metabolic products (metabolic phenotyping or metabotyping) has provided new insights into metabolic syndrome and nonalcoholic fatty liver disease. Data from nuclear magnetic resonance spectroscopy and mass spectrometry combined with statistical modeling and top-down systems biology have allowed us to analyze and interpret metabolic signatures in terms of metabolic pathways and protein interaction networks and to identify the genomic and metagenomic determinants of metabolism. For example, metabolic phenotyping has shown that relationships between host cells and the microbiome affect development of the metabolic syndrome and fatty liver disease. We review recent developments in metabolic phenotyping and systems biology technologies and how these methodologies have provided insights into the mechanisms of metabolic syndrome and nonalcoholic fatty liver disease. We discuss emerging areas of research in this field and outline our vision for how metabolic phenotyping could be used to study metabolic syndrome and fatty liver disease.

    To analyze immediate postoperative outcomes after pancreaticoduodenectomy regarding metabolic syndrome. In two academic centers, postoperative outcomes of patients undergoing pancreaticoduodenectomy from 2002 to 2014 were prospectively recorded. Patients presenting with metabolic syndrome [defined as at least three criteria among overweight (BMI ≥ 28 kg/m²), diabetes mellitus, arterial hypertension and dyslipidemia] were compared to patients without metabolic syndrome. Among 270 consecutive patients, 29 (11%) presented with metabolic syndrome. In univariable analysis, patients with metabolic syndrome were significantly older (69.4 years vs 62.5 years, P = 0.003) and presented more frequently with soft pancreas (72% vs 22%, P = 0.0001). In-hospital morbidity (83% vs 71%) and mortality (7% vs 6%) did not differ in the two groups so as pancreatic fistula rate (45% vs 30%, P = 0.079) and severity of pancreatic fistula (P = 0.257). In multivariable analysis, soft pancreas texture (P = 0.001), pancreatic duct diameter < 3 mm (P = 0.025) and BMI > 30 kg/m² (P = 0.041) were identified as independent risk factors of pancreatic fistula after pancreaticoduodenectomy, but not metabolic syndrome. In spite of logical reasoning and appropriate methodology, present series suggests that metabolic syndrome does not jeopardize postoperative outcomes after pancreaticoduodenectomy. Therefore, definition of metabolic syndrome seems to be inappropriate and fatty pancreas needs to be assessed with an international consensual histopathological classification.

    Vascular risk factors, including metabolic syndrome, are known to contribute to the development of cognitive dysfunction. We tested the hypothesis that patients with metabolic syndrome are more likely to develop cognitive dysfunction after noncardiac surgery. Age- and education-balanced patients (n = 60) undergoing elective noncardiac surgery with and without metabolic syndrome and 30 nonsurgical controls were enrolled. Recent verbal and nonverbal memory and executive functions were assessed using a psychometric test battery before and 1 month after noncardiac surgery or at a 1-month interval in nonsurgical controls. Neurocognitive scores under baseline conditions were similar in surgical patients with versus without metabolic syndrome in all examined cognitive modalities (recent nonverbal and verbal memory, executive functions). Pronounced reductions in tests of verbal memory (delayed story recall, immediate and delayed word list recall) and executive function (backward digit span) were observed in patients with versus without metabolic syndrome after surgery. Overall cognitive performance after surgery was also significantly (P = 0.03) more impaired in patients with versus without metabolic syndrome. The prevalence rate of POCD wasdifferent in the studied groups (17/30 [corrected] and 8/30 in patientswith versus without metabolic syndrome; P < 0.02). The results indicate that cognitive functions were more profoundly impaired in patients with metabolic syndrome undergoing noncardiac surgery compared with their healthier counterparts.

    More than 2 million people in the United States have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). We performed targeted, broad-spectrum metabolomics to gain insights into the biology of CFS. We studied a total of 84 subjects using these methods. Forty-five subjects (n = 22 men and 23 women) met diagnostic criteria for ME/CFS by Institute of Medicine, Canadian, and Fukuda criteria. Thirty-nine subjects (n = 18 men and 21 women) were age- and sex-matched normal controls. Males with CFS were 53 (±2.8) y old (mean ± SEM; range, 21–67 y). Females were 52 (±2.5) y old (range, 20–67 y). The Karnofsky performance scores were 62 (±3.2) for males and 54 (±3.3) for females. We targeted 612 metabolites in plasma from 63 biochemical pathways by hydrophilic interaction liquid chromatography, electrospray ionization, and tandem mass spectrometry in a single-injection method. Patients with CFS showed abnormalities in 20 metabolic pathways. Eighty percent of the diagnostic metabolites were decreased, consistent with a hypometabolic syndrome. Pathway abnormalities included sphingolipid, phospholipid, purine, cholesterol, microbiome, pyrroline-5-carboxylate, riboflavin, branch chain amino acid, peroxisomal, and mitochondrial metabolism. Area under the receiver operator characteristic curve analysis showed diagnostic accuracies of 94% [95% confidence interval (CI), 84–100%] in males using eight metabolites and 96% (95% CI, 86–100%) in females using 13 metabolites. Our data show that despite the heterogeneity of factors leading to CFS, the cellular metabolic response in patients was homogeneous, statistically robust, and chemically similar to the evolutionarily conserved persistence response to environmental stress known as dauer.

    We report the development of a new combinatorial approach that allows for peptide-mediated selective tissue targeting of nuclear hormone pharmacology while eliminating adverse effects in other tissues. Specifically, we report the development of a glucagon-like peptide-1 (GLP-1)-estrogen conjugate that has superior sex-independent efficacy over either of the individual hormones alone to correct obesity, hyperglycemia and dyslipidemia in mice. The therapeutic benefits are driven by pleiotropic dual hormone action to improve energy, glucose and lipid metabolism, as shown by loss-of-function models and genetic action profiling. Notably, the peptide-based targeting strategy also prevents hallmark side effects of estrogen in male and female mice, such as reproductive endocrine toxicity and oncogenicity. Collectively, selective activation of estrogen receptors in GLP-1–targeted tissues produces unprecedented efficacy to enhance the metabolic benefits of GLP-1 agonism. This example of targeting the metabolic syndrome represents the discovery of a new class of therapeutics that enables synergistic co-agonism through peptide-based selective delivery of small molecules. Although our observations with the GLP-1–estrogen conjugate justify translational studies for diabetes and obesity, the multitude of other possible combinations of peptides and small molecules may offer equal promise for other diseases.

    Metabolic syndrome comprises a cluster of related disorders that includes obesity, glucose intolerance, insulin resistance, dyslipidemia, and fatty liver. Recently, gut-derived chronic endotoxemia has been identified as a primary mediator for triggering the low-grade inflammation responsible for the development of metabolic syndrome. In the present study we examined the role of the small intestinal brush-border enzyme, intestinal alkaline phosphatase (IAP), in preventing a high-fat-diet-induced metabolic syndrome in mice. We found that both endogenous and orally supplemented IAP inhibits absorption of endotoxin (lipopolysaccharides) that occurs with dietary fat, and oral IAP supplementation prevents as well as reverses metabolic syndrome. Furthermore, IAP supplementation improves the lipid profile in mice fed a standard, low-fat chow diet. These results point to a potentially unique therapy against metabolic syndrome in at-risk humans.

    Diagnosis of metabolic syndrome includes a set of laboratory and physical findings, including central adiposity, elevated TAG, reduced HDL-cholesterol, hypertension and elevated fasting glucose or insulin resistance. While definitions have varied slightly, from a practical point of view, identifying dietary and lifestyle factors, including low levels of physical activity, are important in designing a diet and exercise programme that can help individuals with the metabolic syndrome to reduce the associated detrimental health consequences. Specific features of the metabolic syndrome require intervention, whether dietary or otherwise, to move towards normal ranges. It is important to remember that no one size or treatment fits all. While central obesity is perceived as the hallmark of the metabolic syndrome, other features need to be treated independently if they do not respond to lifestyle change. The future may hold treatments for the metabolic syndrome that involve modulation of inflammation.

    Diffuse peripheral nerve impairment is common in metabolic syndrome: in patients with metabolic syndrome and carpal tunnel syndrome this might affect the outcome of treatment by local corticosteroid injection. A total of 55 consecutive patients with carpal tunnel syndrome and metabolic syndrome treated with corticosteroid injection (10 mg triamcinolone acetonide) were age and sex matched with 55 control patients without metabolic syndrome. Grip strength, perception of touch with Semmes-Weinstein monofilaments and Boston Carpal Tunnel Questionnaires were assessed at the baseline and at 6, 12 and 24 weeks follow-up. The two groups had similar pre-operative grip strength and Boston Carpal Tunnel Questionnaire scores. The Boston Carpal Tunnel Questionnaire symptom and function scores of the metabolic syndrome group were significantly greater than the control group at 12 and 24 weeks follow-up. Except for significantly greater grip strength at the 12-week follow-up in the control group, there were no significant differences in grip strength between the groups. Semmes-Weinstein monofilament sensory index for the control group was significantly greater than that of the metabolic syndrome group throughout the 24-week follow-up. After 24 weeks, five patients (13%) in the control group and 13 patients (27%) in the metabolic syndrome group had had carpal tunnel surgery. Patients with metabolic syndrome are at risk for poor functional outcome and failure of treatment after corticosteroid injection for carpal tunnel syndrome.

    Metabolic syndrome progresses to diabetes and determinants of this progression like hyperinsulinemia, hypertriglyceridemia and genetic factors have been speculative. The present study was aimed at quantifying the insulin resistance and influence of family history of diabetes in subjects with metabolic syndrome developing prediabetes and diabetes. Consecutive subjects attending the endocrine clinic were evaluated for metabolic syndrome as per definition of International Diabetes Federation, 2005. The family history of diabetes in their first degree relatives was ascertained and Homeostasis model assessment of Insulin resistance (HOMA-IR), Homeostasis model assessment for beta cell function (HOMA-B) and Quantitative insulin sensitivity check index (QUICKI) were calculated in 163 subjects enrolled. HOMA-IR was higher (p<0.05) but HOMA-B and QUICKI were lower (p<0.0001) in subjects with metabolic syndrome+prediabetes or diabetes compared to metabolic syndrome with normal glucose tolerance. HOMA-B was lower and prevalence of prediabetes and diabetes was higher in metabolic syndrome subjects with family history of diabetes than in those without such family history (p<0.05). subjects with metabolic syndrome having prediabetes and diabetes had more severe insulin resistance than those with metabolic syndrome only. Beta cell dysfunction was remarkable and prevalence of prediabetes was high in metabolic syndrome subjects with family history of diabetes. Both the severity of the insulin resistance and family history of diabetes are therefore proposed to be determinants of diminished Beta cell function leading to diabetes in metabolic syndrome.

    Metabolic syndrome is defined as a set of coexisting metabolic disorders that increase an individual's likelihood of developing type 2 diabetes, cardiovascular disease and stroke. Medicinal plants, some of which have been used for thousands of years, serve as an excellent source of bioactive compounds for the treatment of metabolic syndrome because they contain a wide range of phytochemicals with diverse metabolic effects. In order for botanicals to be effectively used against metabolic syndrome, however, botanical preparations must be characterized and standardized through the identification of their active compounds and respective modes of action, followed by validation in controlled clinical trials with clearly defined endpoints. This review assesses examples of commonly known and partially characterized botanicals to describe specific considerations for the phytochemical, preclinical and clinical characterization of botanicals associated with metabolic syndrome.

    The survival of children with cancer has grown considerably in recent years resulting in a marked increase of endocrine complications. increasingly recognized problems are metabolic syndrome and diabetes mellitus. We critically analysed the most recent literature about the prevalence and molecular mechanisms of metabolic dysregulation and long-term cardio-metabolic risk in this population. Hypothalamic irradiation determines growth hormone deficiency and hypogonadism; moreover it is able to disrupt the appetite regulating centre leading to hyperphagia and progressive obesity. These conditions determine an insulin resistant state, contributing to the development of metabolic syndrome and diabetes mellitus. Irradiation and/or chemotherapy may lead to an insulin secretory defect through a direct damage of pancreatic beta cells. Metabolic syndrome and diabetes mellitus represent increasingly recognized long-term complications of childhood cancer treatment. The different impact of insulin resistance and secretory defects on the onset and progression of metabolic syndrome and diabetes mellitus remains unclear.

    Metabolic syndrome, acondition increasing cardiovascular morbidity, mortality and risk for diabetes mellitus type 2, is currently worldwide reaching epidemic proportions. This complex disorder represents an urgent challenge for new pharmacotherapeutic strategies formulation. Pathophysiological mechanisms underlying metabolic syndrome are not completely understood, nevertheless growing evidence is supporting the hypothesis that multiple metabolic dysregulations do contribute to its development. Apotential target for pharmacological intervention is considered to be dysregulation of adipose tissue endocrine/paracrine function. Specific adipokines, proteins secreted by the adipose tissue, with some pleiotropic effects, have been identified with strong association to regulation of energy metabolism, appetite, insulin signaling, tissue insulin sensitivity and the proinflammatory state related to metabolic syndrome. The aim of this paper is to provide a brief overview of endocrine/paracrine functions of the adipose tissue with regard to metabolic syndrome development and pathophysiology and particular adipokines as potential targets for innovative pharmacotherapeutic approaches.

    OBJECTIVE Insulin clearance is decreased in type 2 diabetes mellitus (T2DM) for unknown reasons. Subjects with metabolic syndrome are hyperinsulinemic and have an increased risk of T2DM. We aimed to investigate the relationship between hepatic insulin clearance (HIC) and different components of metabolic syndrome and tested the hypothesis that HIC may predict the risk of metabolic syndrome. RESEARCH DESIGN AND METHODS Individuals without diabetes from the Metabolic Syndrome Berlin Brandenburg (MeSyBePo) study (800 subjects with the baseline examination and 189 subjects from the MeSyBePo recall study) underwent an oral glucose tolerance test (OGTT) with assessment of insulin secretion (insulin secretion rate [ISR]) and insulin sensitivity. Two indices of HIC were calculated. RESULTS Both HIC indices showed lower values in subjects with metabolic syndrome (P < 0.001) at baseline. HIC indices correlate inversely with waist circumference, diastolic blood pressure, fasting glucose, triglycerides, and OGTT-derived insulin secretion index. During a mean follow-up of 5.1 ± 0.9 years, 47 individuals developed metabolic syndrome and 33 subjects progressed to impaired glucose metabolism. Both indices of HIC showed a trend of an association with increased risk of metabolic syndrome (HICC-peptide odds ratio 1.13 [95% CI 0.97–1.31], P = 0.12, and HICISR 1.38 [0.88–2.17], P = 0.16) and impaired glucose metabolism (HICC-peptide 1.12 [0.92–1.36], P = 0.26, and HICISR 1.31 [0.74–2.33] P = 0.36), although point estimates reached no statistical significance. CONCLUSIONS HIC was associated with different components of metabolic syndrome and markers of insulin secretion and insulin sensitivity. Decreased HIC may represent a novel pathophysiological mechanism of the metabolic syndrome, which may be used additionally for early identification of high-risk subjects. PMID:24026549

    Williams-Beuren syndrome (WBS, OMIM-194050) is a neurodevelopmental disorder with multisystemic manifestations caused by a 1.55-1.83 Mb deletion at 7q11.23 including 26-28 genes. Reported endocrine and metabolic abnormalities include transient hypercalcaemia of infancy, subclinical hypothyroidism in ∼ 30% of children and impaired glucose tolerance in ∼ 75% of adult individuals. The purpose of this study was to further study metabolic alterations in patients with WBS, as well as in several mouse models, to establish potential candidate genes. We analysed several metabolic parameters in a cohort of 154 individuals with WBS (data available from 69 to 151 cases per parameter), as well as in several mouse models with complete and partial deletions of the orthologous WBS locus, and searched for causative genes and potential modifiers. Triglyceride plasma levels were significantly decreased in individuals with WBS while cholesterol levels were slightly decreased compared with controls. Hyperbilirubinemia, mostly unconjugated, was found in 18.3% of WBS cases and correlated with subclinical hypothyroidism and hypotriglyceridemia, suggesting common pathogenic mechanisms. Haploinsufficiency at MLXIPL and increased penetrance for hypomorphic alleles at the UGT1A1 gene promoter might underlie the lipid and bilirubin alterations. Other disturbances included increased protein and iron levels, as well as the known subclinical hypothyroidism and glucose intolerance. Our results show that several unreported biochemical alterations, related to haploinsufficiency for specific genes at 7q11.23, are relatively common in WBS. The early diagnosis, follow-up and management of these metabolic disturbances could prevent long-term complications in this disorder. Published by the BMJ Publishing Group Limited.

  20. Understanding cachexia as a cancer metabolism syndrome

    2016-01-01

    Metabolic reprogramming occurs in tumors to foster cancer cell proliferation, survival and metastasis, but as well at a systemic level affecting the whole organism, eventually leading to cancer cachexia. Indeed, as cancer cells rely on external sources of nitrogen and carbon skeleton to grow, systemic metabolic deregulation promoting tissue wasting and metabolites mobilization ultimately supports tumor growth. Cachectic patients experience a wide range of symptoms affecting several organ functions such as muscle, liver, brain, immune system and heart, collectively decreasing patients' quality of life and worsening their prognosis. Moreover, cachexia is estimated to be the direct cause of at least 20% of cancer deaths. The main aspect of cachexia syndrome is the unstoppable skeletal muscle and fat storage wasting, even with an adequate caloric intake, resulting in nutrient mobilization – both directly as lipid and amino acids and indirectly as glucose derived from the exploitation of liver gluconeogenesis – that reaches the tumor through the bloodstream. From a metabolic standpoint, cachectic host develops a wide range of dysfunctions, from increased insulin and IGF-1 resistance to induction of mitochondrial uncoupling proteins and fat tissue browning resulting in an increased energy expenditure and heat generation, even at rest. For a long time, cachexia has been merely considered an epiphenomenon of end-stage tumors. However, in specific tumor types, such as pancreatic cancers, it is now clear that patients present markers of tissue wasting at a stage in which tumor is not yet clinically detectable, and that host amino acid supply is required for tumor growth. Indeed, tumor cells actively promote tissue wasting by secreting specific factors such as parathyroid hormone-related protein and micro RNAs. Understanding the molecular and metabolic mediators of cachexia will not only advance therapeutic approaches against cancer, but also improve patients' quality of

    The prevalence of the metabolic syndrome is rapidly increasing. This syndrome is characterized by metabolic disturbances, such as abnormal lipid and carbohydrate metabolism and a low-grade inflammatory state. PPARs play an important role in these metabolic processes, which makes them effective targets for treatment and prevention of the metabolic syndrome. Synthetic PPAR agonists, such as fibrates and thiazolidinediones are already used to treat hyperlipidemia and diabetes mellitus, respectively. Besides synthetic ligands, dietary fatty acids and fatty acid derivatives can also bind to an activate PPARs. As demonstrated with ligand-binding assays, PPARs have a clear preference of binding polyunsaturated fatty acids. Monounsaturated fatty acids are also very effective in binding PPARs, whereas saturated fatty acids are poor PPAR binders. However, ligand binding does not necessarily mean transcriptional activation. Therefore, it is important to investigate transactivation properties of dietary fatty acids as PPAR agonists and their role in metabolic reactions. Furthermore, human intervention studies comparing the effects of natural versus synthetic ligands side-by-side may reveal specific fatty acids that exert beneficial PPAR-mediated metabolic effects. The ability of PPARs to sense fatty acids and to mediate lipid metabolism, glucose metabolism and the inflammatory state makes them excellent targets for dietary modulation in order to prevent and treat the metabolic syndrome and associated diseases. This review discusses the role and function of PPARs and their ligands in light of the metabolic syndrome.

    Metabolic syndrome (MetS) is a constellation of multiple metabolic risk factors including abdominal obesity, glucose intolerance, insulin resistance, dyslipidemia and hypertension. Over the past decades, the prevalence of metabolic syndrome has increased dramatically, imposing a devastating, pandemic health threat. More importantly, individuals with metabolic syndrome are at an increased risk of diabetes mellitus and overall cardiovascular diseases. One of the common comorbidities of metabolic syndrome is heart anomalies leading to the loss of cardiomyocytes, cardiac dysfunction and ultimately heart failure. Up-to-date, a plethora cell signaling pathways have been postulated for the pathogenesis of cardiac complications in obesity including lipotoxicity, inflammation, oxidative stress, apoptosis and sympathetic overactivation although the precise mechanism of action underscoring obesity-associated heart dysfunction remains elusive. Recent evidence has indicated a potential role of protein quality control in components of metabolic syndrome. Within the protein quality control system, the autophagy-lysosome pathway is an evolutionarily conserved pathway responsible for bulk degradation of large intracellular organelles and protein aggregates. Autophagy has been demonstrated to play an indispensible role in the maintenance of cardiac geometry and function under both physiological and pathological conditions. Accumulating studies have demonstrated that autophagy plays a pivotal role in the etiology of cardiac anomalies under obesity and metabolic syndrome. In this mini review, we will discuss on how autophagy is involved in the regulation of cardiac function in obesity and metabolic syndrome. PMID:24810277

    Metabolic syndrome (MetS) has become a health and financial burden worldwide. The MetS definition captures clustering of risk factors that predict higher risk for diabetes mellitus and cardiovascular disease. Our study hypothesis is that additional to genes influencing individual MetS risk factors, genetic variants exist that influence MetS and inflammatory markers forming a predisposing MetS genetic network. To test this hypothesis a staged approach was undertaken. (a) We analyzed 17 metabolic and inflammatory traits in more than 85,500 participants from 14 large epidemiological studies within the Cross Consortia Pleiotropy Group. Individuals classified with MetS (NCEP definition), versus those without, showed on average significantly different levels for most inflammatory markers studied. (b) Paired average correlations between 8 metabolic traits and 9 inflammatory markers from the same studies as above, estimated with two methods, and factor analyses on large simulated data, helped in identifying 8 combinations of traits for follow-up in meta-analyses, out of 130,305 possible combinations between metabolic traits and inflammatory markers studied. (c) We performed correlated meta-analyses for 8 metabolic traits and 6 inflammatory markers by using existing GWAS published genetic summary results, with about 2.5 million SNPs from twelve predominantly largest GWAS consortia. These analyses yielded 130 unique SNPs/genes with pleiotropic associations (a SNP/gene associating at least one metabolic trait and one inflammatory marker). Of them twenty-five variants (seven loci newly reported) are proposed as MetS candidates. They map to genes MACF1, KIAA0754, GCKR, GRB14, COBLL1, LOC646736-IRS1, SLC39A8, NELFE, SKIV2L, STK19, TFAP2B, BAZ1B, BCL7B, TBL2, MLXIPL, LPL, TRIB1, ATXN2, HECTD4, PTPN11, ZNF664, PDXDC1, FTO, MC4R and TOMM40.

    Metabolic syndrome (MetS) has become a health and financial burden worldwide. The MetS definition captures clustering of risk factors that predict higher risk for diabetes mellitus and cardiovascular disease. Our study hypothesis is that additional to genes influencing individual MetS risk factors, genetic variants exist that influence MetS and inflammatory markers forming a predisposing MetS genetic network. To test this hypothesis a staged approach was undertaken. (a) We analyzed 17 metabolic and inflammatory traits in more than 85,500 participants from 14 large epidemiological studies within the Cross Consortia Pleiotropy Group. Individuals classified with MetS (NCEP definition), versus those without, showed on average significantly different levels for most inflammatory markers studied. (b) Paired average correlations between 8 metabolic traits and 9 inflammatory markers from the same studies as above, estimated with two methods, and factor analyses on large simulated data, helped in identifying 8 combinations of traits for follow-up in meta-analyses, out of 130,305 possible combinations between metabolic traits and inflammatory markers studied. (c) We performed correlated meta-analyses for 8 metabolic traits and 6 inflammatory markers by using existing GWAS published genetic summary results, with about 2.5 million SNPs from twelve predominantly largest GWAS consortia. These analyses yielded 130 unique SNPs/genes with pleiotropic associations (a SNP/gene associating at least one metabolic trait and one inflammatory marker). Of them twenty-five variants (seven loci newly reported) are proposed as MetS candidates. They map to genes MACF1, KIAA0754, GCKR, GRB14, COBLL1, LOC646736-IRS1, SLC39A8, NELFE, SKIV2L, STK19, TFAP2B, BAZ1B, BCL7B, TBL2, MLXIPL, LPL, TRIB1, ATXN2, HECTD4, PTPN11, ZNF664, PDXDC1, FTO, MC4R and TOMM40.

From original research articles extracted from nursing and medical databases. MetS is a constellation of characteristics that increases the risk for the development of diabetes and cardiovascular disease. The pathophysiology of MetS is not completely understood, but is thought to involve a complex interaction between the environment, genetic susceptibility, insulin resistance, and abnormal adipose tissue function. The role of the advanced practice nurse is appropriate for early intervention and counseling of patients with MetS and those who are at risk, as well as addressing the ethical challenges that accompany their care. ©2013 The Author(s) ©2013 American Association of Nurse Practitioners.

    The metabolic syndrome affects 25% of the U.S. population and greatly increases the risk of diabetes and coronary artery disease (CAD). We tested the hypothesis that the metabolic syndrome is associated with impaired coronary vasodilator function, a marker of atherosclerotic disease activity. Four hundred sixty-two patients at risk for CAD, as defined by a low-density lipoprotein cholesterol ≥ 160 mg/dL with fewer than 2 coronary risk factors, a low-density lipoprotein cholesterol ≥ 130 mg/dL with 2 or more coronary risk factors, or with documented CAD were included. A subset of 234 individuals underwent repeated PET at 1 y. Myocardial blood flow (MBF) and vasodilator reserve were assessed by PET. Modified criteria of the National Cholesterol Education Program, Adult Treatment Panel III were used to characterize the metabolic syndrome. Adenosine- and cold-stimulated MBF were similar in patients with and without metabolic syndrome, whereas baseline MBF showed a stepwise increase with increasing features of the syndrome. Consequently, patients with metabolic syndrome showed a lower coronary flow reserve (CFR) (2.5 ± 1.0) than those without metabolic syndrome (3.0 ± 0.9, P = 0.004). Differences in CFR were no longer present after correcting rest flows for the rate-pressure product. Change in MBF and CFR at 1 y were not different across groups of patients with increasing features of the metabolic syndrome. Patients with metabolic syndrome demonstrate impaired CFR, which is related to the augmentation in resting coronary blood flow caused by hypertension. In high-risk individuals, peak adenosine- and cold-stimulated blood flows are impaired even in the absence of the metabolic syndrome.

    There has been a rapid increase in the prevalence of obesity, type 2 diabetes and metabolic syndrome(MetS) over the past two to three decades in most Asian countries. According to the Korean National Health and Nutrition Examination Survey(KNHANES), the prevalence of MetS significantly increased from 24.9% to 31.3% between 1998 and 2007. The clinical significance of MetS is based on the increased risk for the development of cardiovascular disease(CVD). We analyzed the 8-year follow-up data of 2,435 healthy subjects and found that MetS was associated with an increased risk of CVD in both men and women(OR: 1.98, 95% CI: 1.30-3.03 in men; OR: 4.04, 95% CI: 1.78-9.14 in women). MetS was significantly associated with the risk for future coronary heart disease(CHD) in men(OR: 3.68; 95% CI: 1.93-7.01) and stroke in women(OR: 3.96; 95% CI: 1.58- 9.94). We also analyzed the echocardiographic findings of 1,600 healthy subjects to evaluate the relationship between metabolic syndrome and left ventricular diastolic dysfunction(LVDD). The patients with MetS exhibited significant differences in parameters of cardiac structure and the LV diastolic function compared to that observed in the patients without MetS. MetS was associated with an increased risk of LVDD(OR: 1.67; 95% CI: 1.18-2.37). These results suggest that the presence of MetS is associated with an increased risk for the development of serious CVD and abnormal changes in the LV structure and diastolic function, even before the development of overt CVD.

    Metabolic syndrome (MetS) predisposes individuals to cardiovascular disease or stroke development. We aimed at evaluating the prevalence of MetS in a population of acute ischemic stroke (IS) patients from central Poland and at estimating the relationship between MetS and stroke risk. We analyzed 672 IS patients who were consecutively admitted to stroke units. The control group was composed of 612 patients with other neurologic disorders. MetS was diagnosed if 3 of 5 factors were present (obesity, increased blood pressure, increased triglycerides, low high-density lipoprotein [HDL] cholesterol, and fasting hyperglycemia) according to the Unified Criteria for Clinical Diagnosis of the Metabolic Syndrome (2009). MetS was diagnosed in 61.2% of stroke patients versus 18.1% of the control group (P < .001). Multiple logistic regression showed that MetS was 1.8 times more common in women than in men (odds ratio [OR], 1.8; 95% confidence interval [CI], 1.4-2.5). The adjusted OR (95% CI) associated with MetS was 2.44 (1.48-3.64; P < .001) for IS. Hypertension and hypertriglyceridemia were the most frequent disturbances of IS patients (87.2% and 68.2%, respectively). The analysis of the interaction between MetS and its components showed significant associations with hypertension (OR, 2.15; 95% CI, .98-4.24; P < .01), high triglyceride levels (OR, 4.35; 95% CI, 2.87-9.43; P < .0001), and low HDL cholesterol levels (OR, 5.12; 95% CI, 3.15-8.20; P < .001). Over 60% of Polish IS patients have MetS. The prevalence of MetS was significantly higher in women than in men. Thus, MetS may be a risk factor for IS. Copyright © 2015 National Stroke Association.

    There is a high prevalence of metabolic syndrome in liver transplant recipients, a population that tends to be physically inactive. The aim of this study was to characterize physical activity and evaluate the relationship between physical activity and metabolic syndrome after liver transplantation. A cross-sectional analysis was performed in patients more than 3 months after transplantation. Metabolic syndrome was classified according to National Cholesterol Education Panel Adult Treatment Panel III guidelines. Physical activity, including duration, frequency, and metabolic equivalents of task (METs), was assessed. The study population consisted of 204 subjects, with 156 more than 1 year after transplantation. The median time after transplantation was 53.5 months (range = 3-299 months). The mean duration of exercise was 90 ± 142 minutes, and the mean MET score was 3.6 ± 1.5. Metabolic syndrome was observed in 58.8% of all subjects and in 63.5% of the subjects more than 1 year after transplantation. In a multivariate analysis involving all subjects, metabolic syndrome was associated with a time after transplantation greater than 1 year [odds ratio (OR) = 2.909, 95% confidence interval (CI) = 1.389-6.092] and older age (OR = 1.036, 95% CI = 1.001-1.072). A second analysis was performed for only patients more than 1 year after transplantation. In a multivariate analysis, metabolic syndrome was associated with lower exercise intensity (OR = 0.690, 95% CI = 0.536-0.887), older age (OR = 1.056, 95% CI = 1.014-1.101), and pretransplant diabetes (OR = 4.246, 95% CI = 1.300-13.864). In conclusion, metabolic syndrome is common after liver transplantation, and the rate is significantly higher in patients more than 1 year after transplantation. The observation that exercise intensity is inversely related to metabolic syndrome after transplantation is novel and suggests that physical activity might provide a means for reducing metabolic syndrome complications in liver

    The prevalence of obesity in the pediatric population has dramatically increased in the last 30 years. While the adverse health effects of obesity have long been recognized in adults, many of these complications are now understood to begin in early childhood. Obese children and adolescents are significantly more likely than their peers of healthy weight to suffer from obstructive sleep apnea and metabolic syndrome. In turn, affected individuals may experience myriad serious clinical sequelae; neuro-cognitive, psychiatric, cardiovascular, and endocrinologic complications have each been extensively documented. Thus, the spectrum of obesity-related disease represents a serious but preventable threat to personal and family wellness; additionally, it is a source of considerable health care expenditure and represents a national and international health crisis. The optimal care of these patients will be best achieved through the pediatric health care provider's timely recognition of these clinical problems and knowledge of appropriate intervention strategies.

  11. Longitudinal measurement invariance of the metabolic syndrome: is the assessment of the metabolic syndrome stable over time?

    Without verification of longitudinal measurement invariance, researchers cannot be certain whether observed change in the metabolic syndrome reflects true change or changes in assessment or structure of the construct over time. This research tested longitudinal measurement invariance of a 1-factor model of the metabolic syndrome during the course of 6 years. Tests of longitudinal measurement invariance (configural, metric, and scalar) were conducted on 604 men and women who participated in the Spokane Heart Study from 1996 to 2006. Metabolic syndrome indicators included body mass index, triglycerides, high-density lipoprotein, diastolic blood pressure, and fasting glucose. Sequential configural and metric invariance models demonstrated adequate model fit, but the scalar invariance model led to a decrement in fit. Therefore, the theoretical framework of the syndrome and the relationships between the syndrome construct and the indicators appear to be equivalent over time. However, observed values of the metabolic syndrome indicators may differ across time when there is a constant level of the syndrome. Because longitudinal invariance was not fully demonstrated, interpretation of change in the metabolic syndrome over time may be misleading because change may be partly attributable to measurement properties of the indicators. However, a cross-sectional 1-factor model of the metabolic syndrome is supported. Copyright © 2011 Elsevier Inc. All rights reserved.

    The metabolic syndrome is a constellation of specific anthropometric, physiological, and biochemical abnormalities predisposing affected individuals to the development of diabetes and cardiovascular disease. The syndrome is well described in the adult literature. However, its description in the pediatric literature is more limited. Due in large part to the normal physiological changes that occur in children and adolescents with respect to growth and puberty, investigators have also struggled to establish a standard definition of the syndrome in the pediatric age group, hindering coordinated research efforts. However, whatever definition of the syndrome is used, the prevalence of the metabolic syndrome in the pediatric age group has increased worldwide. Insulin resistance is the principal metabolic abnormality that is common to the development of the metabolic syndrome in both children and adults. This review summarizes current research regarding the pathophysiology of insulin resistance and how this may contribute to specific abnormalities seen in children and adolescents with the metabolic syndrome. Specifically, insulin resistance in pediatric patients is correlated with cardiovascular risk factors such as elevated blood pressure, dyslipidemia, and type 2 diabetes mellitus, all of which are significant risk factors for adult disease. In addition, current treatment and prevention strategies, including lifestyle modifications, pharmacologic agents, and certain surgical therapies, are highlighted. The need for collaborative changes at the family, school, city, state, and national levels to address the growing prevalence of the metabolic syndrome in the pediatric age group is also reviewed.

    Although much has been written about laminitis in the context of its association with inflammatory processes, recognition is growing that most cases of laminitis examined by veterinarians in private practice are those associated with pasture grazing, obesity, and insulin resistance (IR). The term 'endocrinopathic laminitis' has been adopted to classify the instances of laminitis in which the origin seems to be more strongly associated with an underlying endocrinopathy, such as either IR or the influence of corticosteroids. Results of a recent study suggest that obesity and IR represent the most common metabolic and endocrinopathic predispositions for laminitis in horses. IR also plays an important role in the pathogenesis of laminitis that develops when some horses or ponies are allowed to graze pastures at certain times of the year. The term equine metabolic syndrome (EMS) has been proposed as a label for horses whose clinical examination results (including both physical examination and laboratory testing) suggest heightened risk for developing laminitis as a result of underlying IR.

    The metabolic syndrome (MetS) is a complex multifactorial disorder and its incidence is on the increase worldwide. Due to the definitive link between obesity and the MetS weight loss strategies are of prime importance in halting the spread of MetS. Numerous epidemiological studies provide evidence linking dietary patterns to incidence of MetS symptoms. As a consequence of the epidemiology studies, dietary intervention studies which analyse the effects of supplementing diets with particular nutrients of interest on the symptoms of the MetS have been conducted. Evidence has shown that lifestyle intervention comprising changes in dietary intake and physical activity leads to an improved metabolic profile both in the presence or absence of weight loss thus highlighting the importance of a multi-faceted approach in combating MetS. Nutritional therapy research is not focused solely on reducing energy intake and manipulating macronutrient intake but is investigating the role of functional foods or bioactive components of food. Such bioactives which target weight maintenance and /or insulin sensitivity may have a potentially positive effect on the symptoms of the MetS. However the efficacy of different functional nutrients needs to be further defined and clearly demonstrated.

    To examine whether total physical activity or activity patterns are associated with metabolic syndrome and its components. Participants include 1994 controls from a case-control study of non-fatal myocardial infarction in Costa Rica (1994-2004). Physical activity was assessed via self-administered questionnaire and patterns were identified using principal components analysis. Metabolic syndrome was assessed via blood samples and anthropometry measurements from in-home study visits. Prevalence ratios (PRs) and 95% confidence intervals (CIs) were calculated using log binomial regression. Adjusted least squares means of metabolic syndrome components were calculated by quintile of total activity and pattern scores. Four activity patterns were identified: rest/sleep, agricultural, light indoor activity, and manual labor. Total activity was not associated with metabolic syndrome. Metabolic syndrome prevalence was 20% lower in participants with the highest scores on the agricultural job pattern compared to those with the lowest (PR: 0.80, 95% CI: 0.68-0.94). Higher total activity was associated with lower triglycerides and lower HDL cholesterol. Higher scores on each pattern were inversely associated with metabolic syndrome components, particularly waist circumference and fasting blood glucose. Patterns or types of physical activity may be more strongly associated with metabolic syndrome and its components than total activity levels. Copyright © 2014 Elsevier Inc. All rights reserved.

    The conventional paradigm of nonalcoholic fatty liver disease representing the "hepatic manifestation of the metabolic syndrome" is outdated. We identified and summarized longitudinal studies that, supporting the association of nonalcoholic fatty liver disease with either type 2 diabetes mellitus or metabolic syndrome, suggest that nonalcoholic fatty liver disease precedes the development of both conditions. Online Medical databases were searched, relevant articles were identified, their references were further assessed and tabulated data were checked. Although several cross-sectional studies linked nonalcoholic fatty liver disease to either diabetes and other components of the metabolic syndrome, we focused on 28 longitudinal studies which provided evidence for nonalcoholic fatty liver disease as a risk factor for the future development of diabetes. Moreover, additional 19 longitudinal reported that nonalcoholic fatty liver disease precedes and is a risk factor for the future development of the metabolic syndrome. Finally, molecular and genetic studies are discussed supporting the view that aetiology of steatosis and lipid intra-hepatocytic compartmentation are a major determinant of whether fatty liver is/is not associated with insulin resistance and metabolic syndrome. Data support the novel paradigm of nonalcoholic fatty liver disease as a strong determinant for the development of the metabolic syndrome, which has potentially relevant clinical implications for diagnosing, preventing and treating metabolic syndrome.

    Metabolic syndrome is a particular state of morbidity characterized by the association of several factors contributing to the increase in the cardiovascular risk. This constellation of factors associates the glucose intolerance and its corollary the hyperglycemia, the overweight, the hypertriglyceridemia, the fall of the HDL-cholesterol and arterial hypertension. In Africa, it is difficult to evaluate in the actual prevalence of the metabolic syndrome. The present study aims was to determine the prediction and prevalence of the metabolic syndrome in a group of nurse--lactating mothers--in Abidjan (Ivory Coast), who were submitted at a particularly rich food lipids. Our populations were composed to 100 lactating women, and we used the definition of « National Cholesterol Education Program-Adult Treatment Panel III ». The results obtained showed that the prevalence of the metabolic syndrome is 7%, and 30% of them are presented an abdominal obesity. Our populations were composed to 100 lactating women, which belong to the Ethie where the habit are to eat, after giving birth, high foods lipids for 6 months.

The results obtained showed that the prevalence of the metabolic syndrome is 7%, and 30% of them are presented an abdominal obesity. The risk to develop a metabolic syndrome in this specific population of nurse is particularly big and it's linked to their eating habits.

    To verify the prevalence of metabolic syndrome and insulin resistance in obese adolescents and its relationship with different body composition indicators. A cross-sectional study comprising 79 adolescents aged ten to 18 years old. The assessed body composition indicators were: body mass index (BMI), body fat percentage, abdominal circumference, and subcutaneous fat. The metabolic syndrome was diagnosed according to the criteria proposed by Cook et al. The insulin resistance was determined by the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) index for values above 3.16. The analysis of ROC curves was used to assess the BMI and the abdominal circumference, aiming to identify the subjects with metabolic syndrome and insulin resistance. The cutoff point corresponded to the percentage above the reference value used to diagnose obesity. The metabolic syndrome was diagnosed in 45.5% of the patients and insulin resistance, in 29.1%. Insulin resistance showed association with HDL-cholesterol (p=0.032) and with metabolic syndrome (p=0.006). All body composition indicators were correlated with insulin resistance (p<0.01). In relation to the cutoff point evaluation, the values of 23.5 and 36.3% above the BMI reference point allowed the identification of insulin resistance and metabolic syndrome. The best cutoff point for abdominal circumference to identify insulin resistance was 40%. All body composition indicators, HDL-cholesterol and metabolic syndrome showed correlation with insulin resistance. The BMI was the most effective anthropometric indicator to identify insulin resistance.

    Identifying rare human metabolic disorders that result from a single-gene defect has not only enabled improved diagnostic and clinical management of such patients, but also has resulted in key biological insights into the pathophysiology of the increasingly prevalent metabolic syndrome. Insulin resistance and type 2 diabetes are linked to obesity and driven by excess caloric intake and reduced physical activity. However, key events in the causation of the metabolic syndrome are difficult to disentangle from compensatory effects and epiphenomena. This review provides an overview of three types of human monogenic disorders that result in (1) severe, non-syndromic obesity, (2) pancreatic beta cell forms of early-onset diabetes, and (3) severe insulin resistance. In these patients with single-gene defects causing their exaggerated metabolic disorder, the primary defect is known. The lessons they provide for current understanding of the molecular pathogenesis of the common metabolic syndrome are highlighted.

    In this issue of the journal, Brima et al. report thought-provoking research providing a potential evolutionary rationale whereby natural selection might have preserved genes that predispose to metabolic syndrome. When CD-1 mice were fed a high fat diet, this induced metabolic changes characteristic of metabolic syndrome. In addition, the high fat diet provided substantial protection from lethality due to infection with Trypanosoma cruzi. The authors hypothesize that the same genes predispose to both metabolic syndrome and protection against infectious disease. Thus, the selective advantage of not dying from infectious disease implicitly provides selective pressure predisposing to metabolic syndrome. This hypothesis follows a similar line of reasoning that has provided explanations for the survival of the HbS mutation for sickle cell disease and renal disease-associated genetic variants in apolipoprotein L1. Variants in these two genes provide protection from malaria and Trypanosoma brucei rhodesiense, respectively.

    Metabolic syndrome includes a clustering of metabolic derangements that cause affected subjects to have an increased risk for developing diabetes, cardiovascular disease, and, according to recent epidemiologic studies, chronic kidney disease. The present review discusses four definitions of metabolic syndrome published by different national and international committees. In an effort to bridge the differences existent in those classifications, a unified definition that recognizes the increased biologic activity of the upper visceral fatty tissue and the strong association of abdominal obesity as a leading part of metabolic syndrome is proposed herein. The diagnosis of metabolic syndrome is reserved for pre-diabetic patients who share the risk of becoming diabetic or developing cardiovascular or chronic kidney disease.

    Subjects with metabolic syndrome--a constellation of cardiovascular risk factors of which central obesity and insulin resistance are the most characteristic--are at increased risk for developing diabetes mellitus and cardiovascular disease. In these subjects, abdominal adipose tissue is a source of inflammatory cytokines such as tumor necrosis factor-alpha, known to promote insulin resistance. The presence of inflammatory cytokines together with the well-documented increased risk for cardiovascular diseases in patients with inflammatory arthritides and systemic lupus erythematosus has prompted studies to examine the prevalence of the metabolic syndrome in an effort to identify subjects at risk in addition to that conferred by traditional cardiovascular risk factors. These studies have documented a high prevalence of metabolic syndrome which correlates with disease activity and markers of atherosclerosis. The correlation of inflammatory disease activity with metabolic syndrome provides additional evidence for a link between inflammation and metabolic disturbances/vascular morbidity.

    The metabolic syndrome (MetS), a cluster of risk factors for cardiovascular disease and type 2 diabetes, has become an important public health problem. Considerable differences in the prevalence of the MetS in human immunodeficiency virus (HIV)-infected subjects have been reported, as a consequence of several limitations regarding the diagnostic critera for MetS. New evidence suggests that the use of optimal waist cut-off points specific for the various ethnic populations could represent a step forward in overcoming these limitations. Also the use of specific cut-off points for measuring upper trunk fat as an adjunctive criterion of MetS in HIV patients with lipodystrophy could represent an interesting new research topic. Although metabolic disorders have been associated indirectly with highly active antiretroviral therapy (HAART), directly with HIV infection per se or with host conditions, current circumstances could change the framework of MetS in the HIV setting: For example, the aging HIV population and newer, less metabolically toxic antiretroviral drugs. Lipotoxicity and adipokines have been focused as key issues for explaining MetS in HIV patients. Several studies have investigated the pathophysiology of MetS and cardiovascular complications in HIV infection. Evidence shows that both HIV infection per se and HIV-related chronic immune activation despite antiretroviral therapy are critical factors linking MetS and cardiovascular complications. Current epidemiological and pathogenetic data on MetS in HIV infection, prevention strategies and therapeutic options for all MetS components are reviewed in the light of the recent Adult Treatment Panel IV recommendations and the new antiretroviral drugs.

  6. Rimonabant: endocannabinoid inhibition for the metabolic syndrome.

    Rimonabant is the first drug to target the endocannabinoid (CB) pathway by inhibiting the actions of anandamide and 2-archidonyl-glycerol on CB1 receptors. This review gives an overview of rimonabant and the CB system and how this system relates to obesity. Rimonabant blocks the central effects of this neurotransmitter pathway involved in obesity and weight control and also blocks the direct effects of CBs on adipocyte and hepatocyte metabolism. Blockade of CB1 receptors leads to a decrease in appetite and also has direct actions in adipose tissue and the liver to improve glucose, fat and cholesterol metabolism so improving insulin resistance, triglycerides and high-density lipoprotein cholesterol (HDL-C) and in some patients, blood pressure. The Rimonabant in Obesity (RIO) trials have shown that rimonabant induces weight loss > 5% in 30-40% of patients and > 10% in 10-20% above both a dietary run-in and long-term hypocaloric management over a 2 year period with a low level of drug-related side effects. Rimonabant therapy is associated with an extra 8-10% increase in HDL-C and a 10-30% reduction in triglycerides and improvements in insulin resistance, glycaemic control in patients with diabetes and also adipokines and cytokines including C-reactive protein over hypocaloric diet therapy. In addition rimonabant abolishes the weight gain associated with smoking cessation and improves the chances of quitting smoking. Thus rimonabant has major effects on both the metabolic syndrome and cardiovascular risk factors thus has the potential to reduce the risks of type 2 diabetes and cardiovascular disease associated with the cardiometabolic phenotype.

    Metabolic syndrome has been associated with an increased risk of breast cancer; however, little is known about the association between metabolic syndrome and percent mammographic density, a strong predictor of breast cancer. We analyzed cross-sectional data from 789 premenopausal and 322 postmenopausal women in the Mexican Teacher's Cohort (ESMaestras). Metabolic syndrome was defined according to the harmonized definition. We measured percent density on mammograms using a computer-assisted thresholding method. Multivariable linear regression was used to estimate the association between density and metabolic syndrome, as well as its components by state (Jalisco, Veracruz) and menopausal status (premenopausal, postmenopausal). Among premenopausal women in Jalisco, women with metabolic syndrome had higher percent density than those without after adjusting for potential confounders including BMI [difference = 4.76; 95% confidence interval (CI), 1.72-7.81]. Among the metabolic syndrome components, only low high-density lipoprotein levels (<50 mg/dL) were associated with significantly higher percent density among premenopausal women in Jalisco (difference = 4.62; 95% CI, 1.73-7.52). Metabolic syndrome was not associated with percent density among premenopausal women in Veracruz (difference = -2.91; 95% CI, -7.19 to 1.38), nor among postmenopausal women in either state. Metabolic syndrome was associated with higher percent density among premenopausal women in Jalisco, Mexico, but was not associated with percent density among premenopausal women in Veracruz, Mexico, or among postmenopausal women in either Jalisco or Veracruz. These findings provide some support for a possible role of metabolic syndrome in mammographic density among premenopausal women; however, results were inconsistent across states and require further confirmation in larger studies. ©2013 AACR.

    We assessed the prevalence of chronic kidney disease (CKD) in a hospital-based screening program in Okinawa, Japan. The significance of metabolic syndrome as a determinant of CKD was examined using multivariate logistic regression analysis. A total of 6980 participants, aged 30-79 years, participated in a screening program in Tomishiro Chuo Hospital. Metabolic syndrome was defined according to the criteria of the Adult Treatment Panel III (ATP III). Data were also analyzed according to the modified criteria of the National Cholesterol Education Program (NCEP) that defines abdominal obesity as a waist circumference of > oe =85 cm in men and > or =90 cm in women. CKD was defined as dipstick proteinuria (> or =1+) or a reduced glomerular filtration rate (GFR). GFR was estimated using the abbreviated Modification of Diet in Renal Disease (MDRD) formula. The prevalence of metabolic syndrome and CKD was 12.8 and 13.7%, respectively. Metabolic syndrome was a significant determinant of CKD (adjusted odds ratio (OR) 1.537 and 95% confidence interval (CI) 1.277-1.850, P<0.0001). The adjusted OR (95% CI) was 1.770 (1.215-2.579, P=0.0029) for those with four metabolic syndrome risk factors compared to those with no metabolic syndrome risk factors. Metabolic syndrome was a significant determinant for younger participants (<60 years; OR 1.686, 95% CI 1.348-2.107, P<0.0001), but not for older participants (> or =60 years; OR 1.254, 95% CI 0.906-1.735, NS). The relationship between the number of metabolic syndrome risk factors and the prevalence of CKD was linear using the modified criteria. The results suggest that metabolic syndrome is a significant determinant of CKD in men under 60 years of age, in Okinawa, Japan.

    To determine the correlation between metabolic syndrome and the distribution of stone components in patients with urolithiasis. Between January 2007 and December 2010, renal or ureteral stones were collected from 712 patients (432 males, 280 females) who underwent surgical intervention at three hospitals in South Korea. Metabolic syndrome was defined according to the latest definition of the International Diabetes Federation, using ethnicity- and sex-specific cut-off values for central obesity. Patients were assessed by factors used in metabolic syndrome. All urinary stones were analyzed using infrared spectrophotometry and categorized according to their main component. The patients' mean age was 55.9 years (range 19-93 years). Of the 712 patients, 347 (48.7%; 205 males, 142 females) had a diagnosis of metabolic syndrome. Calcium oxalate (71.5%), uric acid (15.3%), carbonate apatite (8.0%) and struvite (4.1%) calculi were found as the main stone components. Overall, the proportion of uric acid calculi was markedly higher in patients with rather than without metabolic syndrome (19.6 vs 11.2%; P=0.002). However, the proportion of calcium oxalate, carbonate apatite and struvite calculi did not differ between the two groups. The multivariable-adjusted odds ratio for uric acid calculi according to the metabolic syndrome components indicated that the presence of metabolic syndrome was associated with a 93% increased odds ratio of uric acid calculi compared with the absence of metabolic syndrome. Impaired fasting glucose and hypertriglyceridemia were independent risk factors for uric acid calculi. Metabolic syndrome is associated with a significantly increased risk of uric acid calculi development, especially those with impaired fasting glucose and hypertriglyceridemia. © 2012 The Japanese Urological Association.

    There is still a lack of simple methods and instruments for the early assessment of autonomic dysfunction in metabolic syndrome patients. Assessment of sudomotor function has been proposed to explore autonomic function, and could be used as an early biomarker for metabolic syndrome. In the present study, we use a quick and non-invasive method to measure sudomotor function, and aimed to evaluate its efficacy to identify metabolic syndrome in a Chinese population. Information on the 1,160 Chinese participants involved in the study, such as age, sex, blood pressure, waist circumference, body mass index, fasting plasma glucose and lipid profile, and SUDOSCAN, was recorded. During the sudomotor test, patients were asked to place their bare hands and feet on large electrodes. The test took 2 min to carry out, was painless and no participant preparation was required. A total of 567 participants were diagnosed with metabolic syndrome. The prevalence of metabolic syndrome correlated significantly with increasing SUDOSCAN cardiac risk score (P for trend <0.0001). Furthermore, an increase in cardiac risk score value was associated with an increase in the number of metabolic syndrome components (P for trend <0.0001). Compared with the no-risk group (cardiac risk score <20), participants in the high-risk group (cardiac risk score ≥30) had a 2.83-fold increased risk of prevalent metabolic syndrome (P < 0.0001), and 1.51-fold increased risk (P = 0.01) after adjustments. Autonomic dysfunction is correlated to components of metabolic syndrome. The role of SUDOSCAN in the screening of at-risk populations for metabolic syndrome has to be confirmed by further studies. © 2016 The Authors.

    Stressful life events are associated with the metabolic syndrome in cross-sectional studies, but prospective studies addressing this issue are rare and limited. We therefore evaluated whether the number of stressful life events is associated with incident metabolic syndrome. We assessed the association between the number of stressful life events experienced in the 5 years up until baseline and incident metabolic syndrome after 6.5 years at follow-up in the Hoorn study, a middle-aged and elderly population-based cohort. Participants with prevalent metabolic syndrome at baseline were excluded. Metabolic syndrome was defined according to the Adult Treatment Panel III, including fasting plasma glucose levels, HDL-C levels, triglyceride levels, waist circumference and hypertension. We included 1099 participants (47% male; age 60 ± 7 years). During 6.5 years of follow-up, 238 participants (22%) developed the metabolic syndrome. Logistic regression adjusted for age, sex, education level and follow-up duration showed a positive association between the number of stressful life events at baseline and incident metabolic syndrome [OR 1.13 (1.01-1.27) per event, p = 0.049]. In addition, a Poisson model showed a significant positive association between the number of stressful life events at baseline and the number of metabolic syndrome factors at follow-up [OR 1.05 (1.01-1.11) per event, p = 0.018]. Finally, we observed a significant association between the number of stressful life events at baseline and waist circumference at follow-up [adjusted for confounders β 0.86 (0.39-1.34) cm per event, p < 0.001]. Overall, we concluded that persons who reported more stressful life events at baseline had a significantly increased risk for developing metabolic syndrome during 6.5 years of follow-up, in a middle-aged and elderly population-based cohort.

    1) Nutritional assessment of the diet followed by patients with metabolic syndrome, and 2) biochemical analysis of the oxidation-reduction level in patients with metabolic syndrome. A cross-sectional study was conducted in patients with metabolic syndrome in Murcia. Fifty-three patients, 33 with and 20 without (control group) metabolic syndrome, were selected. The intervention consisted of completion of a recall survey and a test to nutritionally assess dietary intake. Anthropometric and laboratory variables, including those related to antioxidant activity, were also tested. Antioxidant activity was within normal limits in both groups (1.7 ± 0.2 mmol/L in the control group and 1.8 ± 0.1 mmol/L in the metabolic syndrome group) (NS). Superoxide dismutase levels were not significantly different between the groups. Mean glutathione reductase levels (U/L) were higher in the control group as compared to patients with metabolic syndrome (P<.05). As regards oxidative stress biomarkers, mean isoprostane levels were higher in the control group (4.9 ± 6.2 ng/mL) than in metabolic syndrome patients (3.5 ± 3.9 ng/mL) (P<.05). Oxidized LDL values tended to be higher in metabolic syndrome patients (96 ± 23.2U/L) as compared to the control group (86.2 ± 17.3 U/L), but differences were not significant. There is a trend to a poorer nutritional and biochemical profile in patients with metabolic syndrome, who also tend to have a greater degree of oxidative stress. Copyright © 2013 SEEN.

    In the past two decades, the 'metabolic syndrome' has raised much clinical and research interest and remains a controversial topic. The constellation of commonly coexisting cardiovascular risk factors, now known as the metabolic syndrome, has had many definitions which has added to the confusion surrounding the syndrome. Recently, the controversy has been escalated by a joint statement from the American Diabetes Association and the European Association for the Study of Diabetes calling into question the existence and clinical utility of the metabolic syndrome as a discrete clinical entity. Despite the controversy, there is agreement that the risk factors of abdominal obesity, hypertension, elevated glucose and dyslipidemia commonly coexist in the same patient, and are important to identify when assessing an individual patient's risk. Therefore, whether the 'syndrome' is a distinct clinical entity is not important. By definition, a syndrome is a group of signs or symptoms that commonly group together. It remains a useful clinical tool to raise awareness among health care professionals to look for 'nontraditional' cardiovascular risk factors, such as glucose intolerance or elevated waist circumference, in patients with other components of the syndrome, without negating the importance of identifying and treating the other 'traditional' risk factors not identified in the syndrome. It also reminds clinicians of the importance of lifestyle interventions to treat all of the components of the syndrome. Therefore, the 'metabolic syndrome' continues to serve a useful clinical purpose to raise awareness among health care professionals and aid in identifying high-risk individuals.

    Unmyelinated cutaneous axons are vulnerable to physical and metabolic injury, but also capable of rapid regeneration. This balance may help determine risk for peripheral neuropathy associated with diabetes or metabolic syndrome. Capsaicin application for 48 hours induces cutaneous fibers to die back into the dermis. Regrowth can be monitored by serial skin biopsies to determine intraepidermal nerve fiber density (IENFD). We used this capsaicin axotomy technique to examine the effects of exercise on cutaneous regenerative capacity in the setting of metabolic syndrome. Baseline ankle IENFD and 30-day cutaneous regeneration after thigh capsaicin axotomy were compared for participants with type 2 diabetes (n = 35) or metabolic syndrome (n = 32) without symptoms or examination evidence of neuropathy. Thirty-six participants (17 with metabolic syndrome) then joined twice weekly observed exercise and lifestyle counseling. Axotomy regeneration was repeated in month 4 during this intervention. Baseline distal leg IENFD was significantly reduced for both metabolic syndrome and diabetic groups. With exercise, participants significantly improved exercise capacity and lower extremity power. Following exercise, 30-day reinnervation rate improved (0.051 ± 0.027 fibers/mm/day before vs 0.072 ± 0.030 after exercise, p = 0.002). Those who achieved improvement in more metabolic syndrome features experienced a greater degree of 30-day reinnervation (p < 0.012). Metabolic syndrome was associated with reduced baseline IENFD and cutaneous regeneration capacity comparable to that seen in diabetes. Exercise-induced improvement in metabolic syndrome features increased cutaneous regenerative capacity. The results underscore the potential benefit to peripheral nerve function of a behavioral modification approach to metabolic improvement. © 2014 American Neurological Association.

    The association of obesity and other metabolic conditions with osteoarthritis is under debate; however, a strong link between metabolic disturbances is suggested to contribute to increased incidences and progression of osteoarthritis. We examined the association of metabolic syndrome and its components with the incidence of knee osteoarthritis in Iranian population. A community-based study was conducted on a total of 625 Iranian volunteers with the complaint of knee pain. Weight-bearing and anteroposterior plain radiographs of both knees were taken on the day of admission. Metabolic syndrome was diagnosed using the modified Adult Treatment Panel III of the National Cholesterol Education Program criteria. Prevalence rates of metabolic syndrome were 22.5% in males and 11.6% in females (P=0.002). The prevalence rate of knee osteoarthritis was 20.0% in males and 43.8% of females (P<0.001). In both genders, osteoarthritis group had higher serum levels of triglyceride and systolic blood pressure in comparison with non-osteoarthritis group. Women with osteoarthritis had higher Body Mass Index (BMI), however, this association was not observed in men. In females, the presence of osteoarthritis was significantly associated with the presence of metabolic syndrome, with the risk of metabolic syndrome in the osteoarthritis group at 2.187 fold the risk in the non-osteoarthritis group. But, the presence of osteoarthritis was not associated with metabolic syndrome in males. Metabolic syndrome mainly through high BMI is associated with knee osteoarthritis in the Iranian women, but neither metabolic syndrome nor any related components are associated with knee osteoarthritis in men.

    Dietary factors contribute to the risk of developing metabolic syndrome, a disorder associated with an increased risk of developing cardiovascular disease, diabetes mellitus, and some cancers. The objective of this study was to evaluate the association between the intake frequencies of certain food groups, eating habits, and the risk of metabolic syndrome in a cross-sectional study of Korean men. Study participants were recruited from the National Cancer Center in South Korea. A total of 7,081 men aged 30 years and older were recruited between August 2002 and May 2007. Metabolic syndrome was defined as having three or more of the following conditions: obesity, high blood pressure, low high-density lipoprotein cholesterol level, high triglyceride level, and high fasting blood glucose level. The association of metabolic syndrome and sociodemographic characteristics, food intake frequencies, and eating habits assessed by a food frequency questionnaire, was examined. The prevalence rate of metabolic syndrome for men aged 30 to 39, 40 to 49, 50 to 59, and 60+ years was 18.2%, 19.8%, 21.9%, and 20.5%, respectively. The study participants with metabolic syndrome had significantly higher family history of type 2 diabetes mellitus (27.6% vs 21.6%, P<0.001), and were more likely to be current smokers (50.1% vs 45.3%, P=0.005) than their counterparts. Among food group items, participants with metabolic syndrome showed significantly higher intake of seaweed (odds ratio [OR] 1.25, 95% confidence interval [CI] 1.05 to 1.50), and oily foods (OR 1.28, 95% CI 1.04 to 1.57) than participants without metabolic syndrome. In addition, the group with metabolic syndrome was more likely to eat quickly (OR 2.23, 95% CI 1.60 to 3.12 for fast vs slow) and to overeat frequently (OR 2.37, 95% CI 1.85 to 3.05 for more than 4 times a week vs less than once a week). The results suggest that high intake of seaweed and oily foods as well as eating habits such as eating faster and frequent

    Background Acne inversa (AI; also designated as Hidradenitis suppurativa) is a common chronic inflammatory skin disease, localized in the axillary, inguinal and perianal skin areas that causes painful, fistulating sinuses with malodorous purulence and scars. Several chronic inflammatory diseases are associated with the metabolic syndrome and its consequences including arteriosclerosis, coronary heart disease, myocardial infraction, and stroke. So far, the association of AI with systemic metabolic alterations is largely unexplored. Methods and Findings A hospital-based case-control study in 80 AI patients and 100 age- and sex-matched control participants was carried out. The prevalence of central obesity (odds ratio 5.88), hypertriglyceridemia (odds ratio 2.24), hypo-HDL-cholesterolemia (odds ratio 4.56), and hyperglycemia (odds ratio 4.09) in AI patients was significantly higher than in controls. Furthermore, the metabolic syndrome, previously defined as the presence of at least three of the five alterations listed above, was more common in those patients compared to controls (40.0% versus 13.0%; odds ratio 4.46, 95% confidence interval 2.02 to 9.96; P<0.001). AI patients with metabolic syndrome also had more pronounced metabolic alterations than controls with metabolic syndrome. Interestingly, there was no correlation between the severity or duration of the disease and the levels of respective parameters or the number of criteria defining the metabolic syndrome. Rather, the metabolic syndrome was observed in a disproportionately high percentage of young AI patients. Conclusions This study shows for the first time that AI patients have a high prevalence of the metabolic syndrome and all of its criteria. It further suggests that the inflammation present in AI patients does not have a major impact on the development of metabolic alterations. Instead, evidence is given for a role of metabolic alterations in the development of AI. We recommend monitoring of AI patients

    Insulin resistance and the metabolic syndrome are complex metabolic traits and key risk factors for the development of cardiovascular disease. They result from the interplay of environmental and genetic factors but the full extent of the genetic background to these conditions remains incomplete. Large-scale genome-wide association studies have helped advance the identification of common genetic variation associated with insulin resistance and the metabolic syndrome, and more recently, exome sequencing has allowed the identification of rare variants associated with the pathogenesis of these conditions. Many variants associated with insulin resistance are directly involved in glucose metabolism; however, functional studies are required to assess the contribution of other variants to the development of insulin resistance. Many genetic variants involved in the pathogenesis of the metabolic syndrome are associated with lipid metabolism.

    The estimated cardiovascular risk determined by the different risk scores, could be heterogeneous in patients with metabolic syndrome without diabetes or vascular disease. This risk stratification could be improved by detecting subclinical carotid atheromatosis. To estimate the cardiovascular risk measured by different scores in patients with metabolic syndrome and analyze its association with the presence of carotid plaque. Non-diabetic patients with metabolic syndrome (Adult Treatment Panel III definition) without cardiovascular disease were enrolled. The Framingham score, the Reynolds score, the new score proposed by the 2013 ACC/AHA Guidelines and the Metabolic Syndrome Severity Calculator were calculated. Prevalence of carotid plaque was determined by ultrasound examination. A Receiver Operating Characteristic analysis was performed. A total of 238 patients were enrolled. Most patients were stratified as "low risk" by Framingham score (64%) and Reynolds score (70.1%). Using the 2013 ACC/AHA score, 45.3% of the population had a risk ≥7.5%. A significant correlation was found between classic scores but the agreement (concordance) was moderate. The correlation between classical scores and the Metabolic Syndrome Severity Calculator was poor. Overall, the prevalence of carotid plaque was 28.2%. The continuous metabolic syndrome score used in our study showed a good predictive power to detect carotid plaque (area under the curve 0.752). In this population, the calculated cardiovascular risk was heterogenic. The prevalence of carotid plaque was high. The Metabolic Syndrome Severity Calculator showed a good predictive power to detect carotid plaque.

    Background Metabolic syndrome has become a major public health concern, but the role of diet in the etiology of this syndrome is not well understood. This study investigated the association between major dietary patterns and prevalence of metabolic syndrome in a Japanese working population. Methods This cross-sectional study was conducted among 460 municipal employees (284 men and 176 women), aged 21–67 years, who participated in a health survey at the time of periodic checkup. Dietary patterns were derived by using the principal component analysis of the consumption of 52 food and beverage items, which were assessed by a validated brief diet history questionnaire. Metabolic syndrome was defined according to the modified NCEP-ATP III criteria. Logistic regression was used to examine the association between dietary patterns and metabolic syndrome with adjustment of potential confounding variables. Results Three dietary patterns were identified. Westernized breakfast pattern characterized by high intakes of bread, confectionaries, and milk and yogurt but low intakes of rice and alcoholic beverages was inversely associated with prevalence of metabolic syndrome and high blood pressure (P for trend = 0.02 and 0.049, respectively). Animal food pattern characterized by high intakes of fish and shellfish, meat, processed meat, mayonnaise, and egg was not associated with prevalence of metabolic syndrome, but was positively associated with high blood glucose (P for trend = 0.03). Healthy Japanese dietary pattern characterized by vegetables and fruits, soy products, mushrooms, and green tea was not appreciably associated with prevalence of metabolic syndrome or its components. Conclusions The results suggest that westernized breakfast pattern may confer some protection against metabolic syndrome in Japanese. The causality of these associations needs to be confirmed.

    The prevalence of metabolic syndrome and overweight in individuals with normal body weight is connected with higher exposure to type 2 diabetes and cardiovascular diseases. The aim of the study was to evaluate the risk and frequency of occurrence of metabolic syndrome and each of its components among individuals with normal weight. Data were obtained by structured interview, and by measurements of anthropometric factors and blood analyses among 13,172 individuals aged 37-66. The risk of occurrence of metabolic syndrome was analysed in tertiles within the normal range of BMI (18.5-24.9 kg/m(2) ). Metabolic syndrome was diagnosed in 17.27% of individuals with normal weight. A significant increase in the risk of occurrence of metabolic syndrome in females was observed within the second (OR = 2.22; 95% CI: 1.63-3.05) and the third (OR = 3.97; 95% CI: 2.97-5.36) tertiles of normal BMI values. In males, a significantly higher risk of occurrence of metabolic syndrome was noted only in the highest BMI tertile (OR = 2.16; 95% CI: 1.26-3.83), compared to the reference level. A high frequency of occurrence of metabolic syndrome risk factors was observed among individuals with BMI close to the upper cut-off point of the normal range. In order to early diagnose metabolically obese individuals with normal weight it is necessary to check the waist circumference when BMI ≥ 22.5 kg/m(2) in females, and BMI ≥ 23.8 kg/m(2) in males, where abnormal values should be a signal that further examinations should be performed to determine other risk factors of metabolic syndrome.

    To study dyslipidemia types in children with metabolic syndrome. From 1520 children of total population 155 children aged from 9 to 18 years were selected, who formed 2 groups: 1 group--85 children with metabolic syndrome, 2 group--54 children with normal body mass. Anthropometry, blood pressure measurement, estimation of total cholesterol, low density cholesterol, very low density cholesterol, high density cholesterol, tryglicerides in blood were done. The total cholesterol level was 1,1 times higher (p = 0.001), low density cholesterol 1,4 times higher (p = 0.001), very low density cholesterol 1,1 times higher (p= 0.015), tryglicerides 1,1 times higher (p = 0.020) in children with metabolic syndrome than in children of control group. In children with metabolic syndrome sensitively more often IIa, IV dislipidemia types and isolated hypercholesterolemia and less often IIb, III dislipidemia types and high density cholesterol isolated decrease were diagnosed. So children with metabolic syndrome were characterized by atherogenic types of dislipidemias which determine early atherosclerosis development. Children with metabolic syndrome must be examined on the lipid metabolism violation with the aim of its prevention and correction.

    The metabolic syndrome (MS) has become a worldwide health problem. It is difficult for patients to follow a diet/exercise regime that would improve their symptoms, therefore the investigation of agents that may deal with its more serious aspects is an important medical field for research. The cardiovascular consequences associated with the syndrome and some of the therapeutic approaches are discussed. The different agents can be divided into several groups: Inorganic/ organic: Zinc complexes with garlic components as insulino-mimetics; Selenium as antioxidant; Copper, Zinc and Manganese as microcomponents of antioxidant enzymes. Organic: Natural or Synthetic: Glycine is effective in lowering blood pressure, TBARS, intra-abdominal fat tissue and triglycerides in sucrose-fed rats. Pharmaceutical products: Fibrates, Lipid-lowering drugs. Antidiabetics. Anti-gout agents. On the other hand there are natural products such as those of animal origin: Sex hormones (also synthetic) used in the problems of menopause and hypoandrogenism frequently found in the MS, antioxidant Omega-3-oils (fish oils) or Vegetal: for example Digitalis pupurea, century-old cardiovascular medication as well as Magnolia officinalis; Spirulina maxima with beneficial effects as antioxidant and lipid-lowering agent, among others. Prickly Pear Cacti. (Opuntia Ficus- Indica Cochlospermum vitifolium (Willd.) Spreng) whose many properties against diabetes and hypercholesterolemia have been empirically known for many years. Perezone (from Perezia plants, a.k.a. Peonia) described as an antiplatelet aggregating agent. The mixed elements in the Mediterranean diet: Fish, salads (peppers, tomatoes), olive oil, garlic, red wine which combines fish oils, garlic and avocado as well as antioxidants from the rest of its components.

    Metabolic syndrome (MetS) is defined as a cluster of risk factors for type 2 diabetes and cardiovascular disease; it is also an independent risk factor for developing chronic kidney disease (CKD) in the general population. Therefore, CKD has many similarities and associations with MetS, and the individual risk factors constituting MetS-especially insulin resistance and glucose intolerance, hypertension, dyslipidemia, and obesity-are also common features of the early stages of CKD. In the later stages of CKD, uremia per se and uremic complications such as fluid retention, protein-energy wasting, inflammation, and oxidative stress further contribute to an increase in the prevalence of MetS in CKD patients. In addition, PD patients exposed to glucose-based PD fluids have an increased risk of developing metabolic complications. The broad use of MetS in clinical research has raised the awareness of the public and of individual patients concerning the value of lifestyle interventions. However, the definition and pathogenesis of MetS are still debated, and no standardized definition nor proven prognostic value has been established for MetS as a cluster of risk factors for diabetes or cardiovascular disease in PD patients. Furthermore, considering the paradoxical associations of some of the risk factors in MetS with decreased mortality, another set of risk factors-those specific to patients with uremia (for example, inflammation and malnutrition)-and the appropriate cut-off levels to individual MetS risk factors should be taken account at the same time. Also, the benefit of interventions targeting these risk factors should be clarified in further clinical studies.

  6. Periodontal disease: the influence of metabolic syndrome

    PubMed Central

    2012-01-01

    Metabolic syndrome (MetS) is a cluster of cardiovascular risk factors that include obesity, impaired glucose tolerance or diabetes, hyperinsulinemia, hypertension, and dyslipidemia. Recently, more attention has been reserved to the correlation between periodontitis and systemic health. MetS is characterized by oxidative stress, a condition in which the equilibrium between the production and the inactivation of reactive oxygen species (ROS) becomes disrupted. ROS have an essential role in a variety of physiological systems, but under a condition of oxidative stress, they contribute to cellular dysfunction and damage. Oxidative stress may act as a common link to explain the relationship between each component of MetS and periodontitis. All those conditions show increased serum levels of products derived from oxidative damage, promoting a proinflammatory state. Moreover, adipocytokines, produced by the fat cells of fat tissue, might modulate the balance between oxidant and antioxidant activities. An increased caloric intake involves a higher metabolic activity, which results in an increased production of ROS, inducing insulin resistance. At the same time, obese patients require more insulin to maintain blood glucose homeostasis – a state known as hyperinsulinemia, a condition that can evolve into type 2 diabetes. Oxidation products can increase neutrophil adhesion and chemotaxis, thus favoring oxidative damage. Hyperglycemia and an oxidizing state promote the genesis of advanced glycation end-products, which could also be implicated in the degeneration and damage of periodontal tissue. Thus, MetS, the whole of interconnected factors, presents systemic and local manifestations, such as cardiovascular disease and periodontitis, related by a common factor known as oxidative stress.

    This study identified factors associated with unhealthy lifestyle behaviors in people with metabolic syndrome in South Korea. The sample consisted of 1,207 subjects with metabolic syndrome from the Sixth Korea National Health and Nutrition Examination Survey conducted in 2014. High-risk alcohol consumption, smoking, aerobic physical activity, leisure physical activity, excessive carbohydrate intake, and fat intake were measured. A secondary data analysis was performed using chi-square tests and logistic regression. Gender was associated with all unhealthy behaviors. The number of metabolic syndrome components, a poor perceived health status, and attempts to control weight were associated with physical inactivity. Those findings may be helpful to develop a tailored lifestyle modification programs for people with metabolic syndrome.

    Vitamin D deficiency is a worldwide public health problem. Vitamin D deficiency plays key role in the pathophysiology of risk factors of metabolic syndrome which affect cardiovascular system, increase insulin resistance and obesity, stimulate rennin-angiotensin-aldosterone system that cause hypertension. The discovery of vitamin D receptor expressed ubiquitously in almost all body cells such as immune, vascular and myocardial cells, pancreatic beta cells, neurons and osteoblasts suggests an involvement of vitamin D mediated effects on metabolic syndrome. Moreover vitamin D deficiency as well as cardiovascular diseases and related risk factors frequently co-occur. This underlines the importance of understanding the role of vitamin D in the context of metabolic syndrome. The paper provides an insight into the physiology of vitamin D and relationship of vitamin D deficiency with risk factors of metabolic syndrome through observational and supplementation studies.

    Non-alcoholic fatty liver disease (NAFLD) is a clinicopathologic entity increasingly recognized as a major health burden in developed countries. It includes a spectrum of liver damage ranging from simple steatosis to nonalcoholic steatohepatitis (NASH), advanced fibrosis, and rarely, progression to cirrhosis. Recent studies emphasize the role of insulin resistance, oxidative stress and subsequent lipid peroxidation, proinflammatory cytokines, adipokines and mitochondrial dysfunction in the development and progression of NAFLD. Furthermore, accumulating evidence supports an association between NAFLD and metabolic syndrome. Although the data are mainly epidemiological, the pathogenesis of NAFLD and metabolic syndrome seems to have common pathophysiological mechanisms, with focus on insulin resistance as a key factor. This review summarizes the current knowledge on the epidemiology, pathophysiology and diagnosis of both NAFLD and metabolic syndrome and the findings that strongly support the association of nonalcoholic fatty liver disease as a possible component in the cluster of metabolic syndrome.

    In recent years, there has been a greater concern about the presence of obesity and metabolic syndrome in children and adolescents. However, there is no consensus regarding the diagnosis of metabolic syndrome in children and adolescents. It is evident that each component of the syndrome must be identified as early as possible in order to prevent definitive lesions. The question is how to do this and which cut-offs must be adopted for this diagnosis. For a matter of convenience, the definition chosen as the most appropriate is the one proposed by the IDF, with cut-offs fixed for pressure, lipids and glycemia, and abdominal circumference points assessed by percentile. Although on the one hand this definition could fail to include some children in the diagnosis of Metabolic Syndrome, on the other hand, it would be of easier acceptance as it does not use multiple tables to assess several anthropometric and metabolic criteria.

    Metabolic syndrome and its components are severe global health issues that are increasing in frequency as the prevalence of obesity increases. Various studies have established a correlation between metabolic syndrome and diseases including, diabetes mellitus, non-alcoholic fatty liver disease, cirrhosis, and cardiovascular disease. In recent years, correlations have also been detected between obesity and metabolic syndrome and the prevalence of certain types of cancer. The current study examines whether obesity and metabolic syndrome components are risk factors for cancer among the adult population in Israel. A cohort study analysis was performed of 24,987 initially healthy men and women who underwent yearly medical assessments at the Institute for Medical Screening in the Sheba Medical Center. Data from the Institute for Medical Screening database was correlated with that from the Israel Cancer Center in the Ministry of Health updated to December 2013. The correlation between metabolic syndrome, obesity, and the overall risk of cancer as well as the risks of specific types of cancer were examined. Of 20,444 subjects for whom complete data were available, 1535 were diagnosed with cancer during the mean follow-up time of 104.3months. In a multi-variant analysis, no significant correlation was found between metabolic syndrome or obesity and the incidence of cancer. When the data were stratified by gender and cancer type, however, a significant association between metabolic syndrome and breast cancer in women was observed (P=0.03, HR=1.67, 95% CI=1.05-2.67). Metabolic syndrome correlates with higher than expected breast cancer incidence in women. Copyright © 2016 European Federation of Internal Medicine. Published by Elsevier B.V. All rights reserved.

    Metabolic syndrome increases risk for atherosclerotic coronary artery disease, and its prevalence increases with increasing age and body mass index. Adults with congenital heart disease (ACHD) are now living longer and accruing coronary artery disease risk factors. However, the prevalence of metabolic syndrome in ACHD patients is unknown. We conducted a retrospective cohort study of ACHD patients at our center to quantify the prevalence of metabolic syndrome in an ACHD population. Using case-control matching, we constructed a comparable control group from a population-based sample of 150 104 adults. International Diabetes Federation criteria were used to define metabolic syndrome. We used logistic regression to compare the risk of metabolic syndrome across the resulting cohorts, which were composed of 448 ACHD patients and 448 controls matched by age and sex. Mean age of both groups was 32.4±11.3 years, and 51.3% were female. Obesity was present in 16.1% of the ACHD patients and 16.7% of the controls. Metabolic syndrome was more common in ACHD patients than in controls (15.0% versus 7.4%; odds ratio 1.82, 95% CI 1.25-2.65). Our data suggest that metabolic syndrome is more common among adults with congenital heart disease than in the general population. Thus, patients with congenital heart disease should be screened for metabolic syndrome and risk factors mitigated where possible to prevent atherosclerotic coronary artery disease. Preventive cardiology should be included during routine ACHD care. © 2016 The Authors. Published on behalf of the American Heart Association, Inc., by Wiley Blackwell.

    We performed this study to investigate associations between metabolic syndrome, chronic kidney disease (CKD), and gout. We reviewed the medical records of 151 patients with gout at the Department of Rheumatology in Korea University Ansan Hospital. The following measures were examined: waist circumference, blood pressure, alcohol consumption, and levels of triglyceride, high density lipoprotein cholesterol, fasting serum glucose, serum uric acid (SUA), creatinine, insulin, and C-peptide. We assessed metabolic syndrome by the homeostasis model assessment of insulin resistance (HOMA-IR) index and renal function by the Modification of Diet in Renal Disease equation; patients were classified according to World Health Organization Asia-Pacific obesity criteria. The prevalence of metabolic syndrome in gout patients (50.8%) was higher than in non-gout patients. The mean SUA level was significantly higher in gout patients with metabolic syndrome (9.13 ± 3.15 mg/dL) than in gout patients without metabolic syndrome (8.14 ± 2.07 mg/dL). The mean SUA level was also significantly higher in patients with gout and CKD (9.55 ± 2.86 mg/dL) than in patients with gout but no CKD (7.74 ± 2.27 mg/dL). In gout patients, HOMA-IR was positively correlated with waist circumference (r = 0.409, p = 0.001). The prevalence of metabolic syndrome in patients with gout was 50.8%, which is higher than the prevalence in the general Korean population. Hyperuricemia in gout patients was correlated with metabolic syndrome and CKD. Insulin resistance may provide clues to better understand the relationship between metabolic syndrome, CKD, and gout.

    The prevalence of metabolic syndrome has been increasing worldwide, however its association with prostate cancer (CaP) is unclear. We reviewed patients undergoing robot assisted radical prostatectomy (RARP) to evaluate if those with metabolic syndrome had more aggressive disease. A prospective database of patients undergoing RARP between January 2005 and December 2008 (n = 2756) was queried for components of metabolic syndrome (BMI ≥ 30 and ≥ 2 of the following: hypertension, diabetes or elevated blood glucose, and dyslipidemia; n = 357). Patients with no components of metabolic syndrome were used as controls (n = 694). Biopsy and final pathology were compared between the 2 groups using all controls, and using best-matched controls (n = 357) based on greedy matching by propensity score. Compared with unmatched controls, metabolic syndrome patients had higher pathology Gleason grade (≥ 7: 78% vs. 64%, P < 0.001) and higher pathologic stage (≥ T3 disease: 43% vs. 31%, P < 0.001). After controlling for confounders, those with metabolic syndrome when compared with best-matched controls had maintained the greater pathology Gleason grade (≥ 7: 78% vs. 64%, P < 0.001) and pathologic stage (≥ T3 disease: 43% vs. 32%, P < 0.001). They also had significantly greater pathologic upgrading of Gleason grade 6 adenocarcinoma found on biopsy compared with best-matched controls (63% vs. 45%, P < 0.001). On pathology, a 2-fold increase in Gleason 8 and greater was noted between patients with metabolic syndrome and best-matched controls (15% vs. 8%). After controlling for confounders, patients with metabolic syndrome were found to have higher Gleason grade and tumor stage on final pathology and were more likely to have upgrading.

    Aims To investigate risk factors for metabolic syndrome in prepubertal boys with Klinefelter syndrome. Methods Eighty-nine boys with Klinefelter syndrome, ages 4–12.9 years, and 34 age-matched control boys had height, weight, waist circumference and blood pressure measured and their parents completed a questionnaire about physical activity. The boys with Klinefelter syndrome also had measurement of lipids, fasting glucose and insulin. Insulin-glucose homeostasis model assessment was calculated, and the boys were evaluated for childhood metabolic syndrome. Results The Klinefelter syndrome and control groups were similar ages (7.5 ± 2.4 vs. 8.1 ± 2.3 years). Body mass index measurements were similar, but waist circumference was >90‰ in 30% of boys with Klinefelter syndrome versus 21% of controls. The mean daily time spent running was 42 min less in the Klinefelter syndrome versus control groups (p < 0.01). About 37% of the boys with Klinefelter syndrome had elevated LDL cholesterol, 24% had insulin resistance, and 7% met the three criteria for diagnosis of metabolic syndrome. Conclusions Truncal obesity, insulin resistance and metabolic syndrome are present in boys as young as 4–12 years with Klinefelter syndrome, and these occur in association with reduced running-type activity.

    High dietary glycaemic carbohydrate, as measured by the dietary glycaemic index and glycaemic load has been associated with increased risk of the metabolic syndrome in adults, but limited research exists for younger populations. We aimed to evaluate associations between dietary glycaemic carbohydrate and insulin resistance or the prevalence of the metabolic syndrome defined by three different criteria in a population-based adolescent cohort. Diet was assessed using 3 day food records in 769 adolescents aged 13-15 years participating in the Western Australian Pregnancy Cohort (Raine) Study. The metabolic syndrome was identified using age-specific adolescent definitions from the International Diabetes Federation, the National Cholesterol Education Program Adult Treatment Panel III and a population-derived 'high-risk' metabolic cluster algorithm. Presence of a high waist circumference was mandatory only in the International Diabetes Federation definition. Insulin resistance was measured using homeostasis model assessment (HOMA-IR). The prevalence of the metabolic syndrome as defined by the International Diabetes Federation and the Adult Treatment Panel III was 3.6 and 4.0%, respectively; 25.9% of subjects were classified into the high-risk cluster. Significantly increased odds of International Diabetes Federation-defined metabolic syndrome were independently associated with a 20 unit glycaemic load increase (odds ratio 2.18; 95% confidence interval 1.26-3.78) and a 30 g carbohydrate increase (odds ratio 3.86; 95% confidence interval 1.80-8.28). No significant associations were observed when using the Adult Treatment Panel III, or the cluster-defined metabolic syndrome, or with HOMA-IR. This study supports the concept that high dietary glycaemic carbohydrate is associated with a higher prevalence of the metabolic syndrome in adolescents. However, relationships vary according to the definition of the metabolic syndrome used, with waist circumference a potentially

    Background: The metabolic syndrome is a clustering of metabolic abnormalities and has been associated with increased risk of type 2 diabetes mellitus and cardiovascular disease. This study aimed to estimate the prevalence of the metabolic syndrome among employees in Northeast China. Methods: Totally, 33,149 employees who received health screening in the International Health Promotion Center in the First Hospital of Jilin University were enrolled. Height, weight, waist circumference, blood pressure, fasting plasma glucose, triglyceride, high-density lipoprotein, and low-density lipoprotein were recorded. Three definitions for the metabolic syndrome were applied, revised National Cholesterol Education Program's Adult Treatment Panel III (NCEP ATP III) criteria, the International Diabetes Federation (IDF) criteria, and the Chinese Diabetes Society (CDS) criteria. Results: Overall, the age-standardized prevalence of the metabolic syndrome was 22.9%, 20.6%, and 15.3% based on definitions of revised NCEP ATP III criteria, the IDF criteria, and the CDS criteria, respectively. Men had higher age-standardized prevalence than women in all three definitions (P < 0.05). The prevalence was 27.1%, 24.5%, and 20.4% for men; 17.1%, 15.4%, and 8.3% for women, respectively. The most common metabolic component with the metabolic syndrome was overweight (54.7% of men had an elevated body mass index, and 35.9% of women had central obesity). Conclusions: A large proportion of employees among Northeast China have the metabolic syndrome. These findings place emphasis on the need to develop aggressive lifestyle modification for patients with the metabolic syndrome and population level strategies for the prevention, detection, and treatment of cardiovascular risk.

    Background Little data exists describing the impact that walking has on metabolic syndrome (MetS) in a multicultural sample of older adults. Methods Walking was measured via pedometer in 150 older adults from 4 different ethnic categories. Steps per day were classified as low (<3100 steps/d) or high (≥3100 steps/d) for statistical analyses. Results Occurrence of MetS was lower in the white (33%) versus non-white population (50%). Low steps/d were related to an increase in MetS for both white (OR = 96.8, 95% CI 12.3–764.6) and non-white individuals (OR = 4.5, 95% CI 1.8–11.3). Low steps/d also increased the odds for selected components of MetS in both the white and non-white groups. Conclusion Low levels of walking increase the likelihood of having MetS in both white and non-white older adults. Efforts to increase walking in older adults may decrease the likelihood of developing this clustering of disease risk factors. PMID:18209231

    Zhou, Ji-Yin; Chan, Lawrence; Zhou, Shi-Wen

    2014-01-01

    Omentin is an adipokine preferentially produced by visceral adipose tissue with insulin-sensitizing effects. Its expression is reduced in obesity, insulin resistance and type 2 diabetes. Omentin is also positively related with adiponectin, high-density lipoprotein levels and negatively related with body mass index, waist circumference, insulin resistance, triglyceride and leptin levels. Lower plasma omentin levels contribute to the pathogenesis of insulin resistance, type 2 diabetes and cardiovascular diseases in obese or overweight patients. Omentin has anti-inflammatory, antiatherogenic, anti-cardiovascular disease and antidiabetic properties. With respect to vascular biology, omentin causes vasodilatation of blood vessels and attenuates C-reactive protein-induced angiogenesis. The ability of omentin to reduce insulin resistance in conjunction with its anti-inflammatory and anti-atherogenic properties makes it a promising therapeutic target. Thus, omentin may have beneficial effects on the metabolic syndrome and could potentially be used as a biologic marker and/or pharmacologic agent/target in this respect.

    Reports about medical consequences from sedentary work are contradictory. It might be associated with the metabolic syndrome (MS), a collection of cardiovascular risk factors including hypertension, dyslipidemia, insulin resistance and central obesity. No data are currently available on workers using visual display units (VDIU), a potential high risk group, given the sedentariness inherent in this work. We evaluated MS prevalence in 1547 VDU users with a mean age of 29.7 years and in a control group of 892 individuals with a mean age of 30.2 years who performed non-sedentary work, selected on the basis of similar demographic data. Physical examination and laboratory tests useful for MS diagnosis were performed. MS prevalence was 3.10% in VDU users vs 2.01% in controls (OR 2.048, 95% CI 1.169 to 3.587, p = 0.012). Significance persisted after controlling for confounding factors (e.g, smoking and leisure activity) in a multivariate analysis (OR 1.555, 95% CI 1.03 to 2.690, p < 0.05). MS should carefully considered when performing health surveillance programmes in VDU users.

    The metabolic syndrome (MetS) is a cluster of cardiometabolic disorders that result from the increasing prevalence of obesity. The major components of MetS include insulin resistance, central obesity, dyslipidemia, and hypertension. MetS identifies the central obesity with increased risk for cardiovascular diseases (CVDs) and type-2 diabetes mellitus (T2DM). Patients with rheumatic diseases, such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and ankylosing spondylitis, have increased prevalence of CVDs. Moreover, CVD risk is increased when obesity is present in these patients. However, traditional cardiovascular risk factors do not completely explain the enhanced cardiovascular risk in this population. Thus, MetS and the altered secretion patterns of proinflammatory adipokines present in obesity could be the link between CVDs and rheumatic diseases. Furthermore, adipokines have been linked to the pathogenesis of MetS and its comorbidities through their effects on vascular function and inflammation. In the present paper, we review recent evidence of the role played by adipokines in the modulation of MetS in the general population, and in patients with rheumatic diseases. PMID:24741591

    The objective of this study was to identify the potential risk factors of metabolic syndrome (MetS) among Chinese schoolchildren. A cross-sectional study among 624 children (357 boys and 267 girls, aged 9.6 ± 0.7 years) was conducted in Wuhan, China, from May to June 2010. MetS was defined according to the criteria proposed by De Ferranti and the International Diabetes Federation (IDF) criteria. Data on cardiorespiratory fitness (CRF), household income, parental hypertension, and children's personal information, including birth weight, preterm birth, and breast-feeding, reported by their parents were obtained. Multiple logistic regression showed that CRF (odds ratio [OR] = 0.68; 95% confidence interval [CI] = 0.60-0.77), breast-feeding (OR = 0.32; 95% CI = 0.10-0.97), and paternal hypertension (OR = 5.06; 95% CI = 1.20-21.37) were all independently associated with MetS. In conclusion, low CRF and paternal hypertension significantly increase the risk, whereas breast-feeding may reduce the risk of MetS among Chinese schoolchildren.

The prevalence of MS was 65% (NCEP-ATP III) and 67.5% (IDF) and was greater in women (NCEP-ATP III=72.8%, IDF=73.6%) than in men (NCEP-ATP III=50.7%; IDF=56.3%). The mean age of patients diagnosed with MS by both diagnostic criteria were similar: 84.7 years. MS was not associated with an increased prevalence of CVD. MS is highly prevalent in elderly hospitalized patients, being higher in women, with both diagnostic criteria (NCEP- ATP III and IDF). In our population the MS was not associated with an increased prevalence of CVD. Copyright © 2013 SEGG. Published by Elsevier Espana. All rights reserved.

    Toward the end of the last century a better knowledge of cardiovascular (CV) risk factors and their associations led investigators to propose the existence of a unique pathophysiological condition called "metabolic" or "insulin resistance syndrome". Among all, insulin-resistance and compensatory hyperinsulinemia are considered its most important treatment targets. Different definitions have been provided by World Health Organization (WHO) and by The Third Report of The National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP III). In particular, abdominal obesity, hypertension, low HDL cholesterol and hyperglicemia are the most common items used for its definition. The presence of MetS is effective in predicting the future risk of diabetes and coronaropathies. The evidence of a higher CV risk rate among different rheumatic inflammatory diseases has recently been associated with high prevalence of MetS in some cases. Rheumatoid or psoriatic arthritis have the large series among arthritis, whereas systemic lupus erythematosus among connective tissue disorders. This review analyses all most important studies about the evidence of MetS in rheumatic patients and the main clinical and prognostic significance of this relation.

    The metabolic syndrome (MetS) is a cluster of cardiometabolic disorders that result from the increasing prevalence of obesity. The major components of MetS include insulin resistance, central obesity, dyslipidemia, and hypertension. MetS identifies the central obesity with increased risk for cardiovascular diseases (CVDs) and type-2 diabetes mellitus (T2DM). Patients with rheumatic diseases, such as rheumatoid arthritis, osteoarthritis, systemic lupus erythematosus, and ankylosing spondylitis, have increased prevalence of CVDs. Moreover, CVD risk is increased when obesity is present in these patients. However, traditional cardiovascular risk factors do not completely explain the enhanced cardiovascular risk in this population. Thus, MetS and the altered secretion patterns of proinflammatory adipokines present in obesity could be the link between CVDs and rheumatic diseases. Furthermore, adipokines have been linked to the pathogenesis of MetS and its comorbidities through their effects on vascular function and inflammation. In the present paper, we review recent evidence of the role played by adipokines in the modulation of MetS in the general population, and in patients with rheumatic diseases.

    Growing data show the association of metabolic syndrome (MetS) or its components with cancer development and cancer-related mortality. It is suggested that in MetS and cancer association, insulin resistance and insulin-like growth factor 1 system play a key role, especially adipokines secreted from visceral adipocytes, free fatty acids and aromatase activity contribute to this process. It is also reported that MetS has a link with colorectal, breast, endometrial, pancreas, primary liver and, although controversial, prostate cancer. Although every component of MetS is known to have an association with cancer development, it is still debated whether the effects of these components are additive or synergistic. On the other hand, in the association between MetS and cancer, the role of antidiabetic and antihypertensive treatments including thiazolidinedione, insulin, angiotensin receptor blockers is also suggested. The primary approach in MetS-cancer relation is to prevent risk factors. Life style changes including weight loss and a healthy diet are known to decrease cancer risk in normal population. It is postulated that an insulin-sensitizing agent, metformin, has cancer-preventing effects on diabetic patients. This review discusses the relationship between MetS and cancer from different aspects and examines this relationship in some of the cancers suggested to be linked with MetS. © 2016 S.

    To determine the prevalence of and sex differences related to the metabolic syndrome among obese and overweight elementary school children. Subjects were 471 overweight or obese Japanese children. Children meeting at least three of the following five criteria qualified as having the metabolic syndrome: abdominal obesity, elevated blood pressure, low high-density lipoprotein-cholesterol levels, high triglyceride levels, and high fasting glucose levels. Fasting insulin levels were also examined. Japanese obese children were found to have a significantly lower prevalence (17.7%) of the metabolic syndrome than U.S. obese adolescents (28.7%, p = 0.0014). However, Japanese overweight children had a similar incidence (8.7%) of the metabolic syndrome compared with U.S. overweight adolescents (6.8%). Hyperinsulinemia in girls and abdominal obesity in boys are characteristic features of individual metabolic syndrome factors in Japanese children. The prevalence of the metabolic syndrome is not lower in preteen Japanese overweight children than in U.S. overweight adolescents, although it is significantly lower in Japanese obese preteen children than in U.S. obese adolescents. Primary and secondary interventions are needed for overweight preteen children in Japan.

    Metabolic syndrome comprises a cluster of cardiovascular risk factors (hypertension, altered glucose metabolism, dyslipidemia, and abdominal obesity) that occur in obese children. However, metabolic syndrome can also occur in lean individuals, suggesting that obesity is a marker for the syndrome, not a cause. Metabolic syndrome is difficult to define, due to its nonuniform classification and reliance on hard cutoffs in the evaluation of disorders with non-Gaussian distributions. Defining the syndrome is even more difficult in children, owing to racial and pubertal differences and lack of cardiovascular events. Lipid partitioning among specific fat depots is associated with insulin resistance, which can lead to mitochondrial overload and dysfunctional subcellular energy use and drive the various elements of metabolic syndrome. Multiple environmental factors, in particular a typical Western diet, drive mitochondrial overload, while other changes in Western society, such as stress and sleep deprivation, increase insulin resistance and the propensity for food intake. These culminate in an adverse biochemical phenotype, including development of altered glucose metabolism and early atherogenesis during childhood and early adulthood. PMID:23356701

    Metabolic syndrome, which is extremely common in developed and some developing countries, is a clustering of at least three of five of the following medical conditions: abdominal obesity, elevated blood pressure, elevated fasting plasma glucose, high serum triglycerides, and low high-density lipoprotein levels. It has been proved that there is a strong association between metabolic syndrome and breast cancer. Metabolic syndrome could increase the risk of breast cancer and influence the prognosis of the breast cancer patients. Some characteristic of metabolic syndrome such as obesity and lack of physical exercise are all risk factors for developing breast cancer. The metabolic syndrome mainly include obesity, type 2 diabetes, hypercholesterolemia and nonalcoholic fatty liver disease, and each of them impacts the risk of breast cancer and the prognosis of the breast cancer patients in different ways. In this Review, we focus on recently uncovered aspects of the immunological and molecular mechanisms that are responsible for the development of this highly prevalent and serious disease. These studies bring new insight into the complex associations between metabolic syndrome and breast cancer and have led to the development of novel therapeutic strategies that might enable a personalized approach in the management of this disease.

    OBJECTIVE—To investigate the prevalence of metabolic syndrome in the Spanish working population and determine how the prevalence varies according to occupation and sex. RESEARCH DESIGN AND METHODS—This was a cross-sectional study of 259,014 workers (mean age 36.4 years, range [16–74]; 72.9% male) who underwent a routine medical checkup. The Adult Treatment Panel III (2001) definition for metabolic syndrome was used. RESULTS—The prevalence of metabolic syndrome was 11.6% (95% CI 11.5–11.7) in male subjects and 4.1% (4.0–4.2) in female subjects and increased with age. The prevalence of metabolic syndrome varied in the different categories of occupational activity depending on the sex considered. Among female subjects, the age-adjusted prevalence of metabolic syndrome was higher in blue-collar than in white-collar workers, but this difference was not evident among male workers. CONCLUSIONS—The prevalence of metabolic syndrome varies in the different categories of occupational activity in the Spanish working population. This variation also depends on sex. PMID:18753667

    Limited literature suggests that sexual dysfunction in women covaries with the metabolic syndrome. This study examined the association of sexual function with metabolic syndrome and cardiovascular disease in healthy older women. There were 376 postmenopausal, community-dwelling women from the Rancho Bernardo Study (mean baseline age = 73 years) that completed a clinic visit during 1999-2002 and returned the Female Sexual Function Index (FSFI) questionnaire mailed in 2002. Thirty-nine percent reported being sexually active; 41.5% met a diagnosis of metabolic syndrome. The number of metabolic syndrome components was strongly associated with decreased sexual activity, desire, and low sexual satisfaction. Waist girth, diabetes, and hypertension were associated with decreased sexual activity. Elevated triglycerides were associated with low desire. Among the cardiovascular endpoints, heart attack, coronary artery bypass, and angina were associated with decreased sexual activity, but not with sexual desire or satisfaction. Past diagnosis of heart failure, poor circulation, and stroke were not associated with sexual function. Sexually active women with metabolic syndrome met criteria for sexual dysfunction in desire, arousal, orgasm, and satisfaction domains. The FSFI Total Score did not differ significantly between sexually active and inactive women. Metabolic syndrome was associated with decreased sexual activity, desire, and satisfaction in all women and with sexual dysfunction in most domains in sexually active women. Coronary artery disease was more prevalent in women with low sexual activity. Copyright © 2016 Elsevier Inc. All rights reserved.

    Links between metabolic syndrome and prostate cancer after androgen deprivation therapy are emerging. The aim of the research was to investigate the association of metabolic syndrome and aggressive prostate malignancy, at initial diagnosis, without the influence of hormonal treatment. Retrospective analysis of 133 patients with prostate tumor diagnosis between 2007 and 2009 was conducted. Patients with prostate cancer were subdivided in 2 groups according to Gleason score: Gleason score≥7 as high-grade prostate tumor (Group 1) and <7 (Group 2) as low-grade prostate tumor. Metabolic syndrome was defined according to International Diabetes Federation and the American Heart Association/National Heart, Lung, and Blood Institute definition. Metabolic syndrome was significantly associated with aggressive prostate cancer (OR 1.87, p<0.05) and a reduced risk of low-grade prostate cancer (OR 0.53, p<0.05) at initial diagnosis, without the influence of endocrine therapy. In our study, patients with metabolic syndrome were more likely to present with more aggressive prostate carcinoma vs. patients without metabolic syndrome. Further research should elucidate these relations in larger samples to confirm these associations and to stabilize future prevention and therapeutic strategies. © Georg Thieme Verlag KG Stuttgart · New York.

    Metabolic syndrome is generally considered as a complication of modernity. Here we searched for the presence of metabolic syndrome components among the Ottoman emperors who lived between 1258 and 1926. Collections of historical archives, which were published as books specifically about morbidity and mortality of Ottoman emperors were reviewed to diagnose metabolic syndrome according to modified criteria by American College of Endocrinology and American Association of Clinical Endocrinologists. Nineteen of 36 dynasty members (53%) had fatal or non-fatal cardiovascular events. Twenty-nine of the dynasty (81%) members were either depicted as truncal obese or reported to have obesity. Thirteen emperors (36%) satisfied diagnostic criteria for metabolic syndrome, retrospectively. Overall, 42% of non-commanding emperors, but 26% of commanding-emperors (who were assumed to be athletically grown and physically more active) were found to have metabolic syndrome (p=0.553). We suggest firstly here that sedentary palace lifestyle exacerbated metabolic syndrome in Ottoman dynasty especially in elderly members, thereafter complicated by cardiovascular events, even in pre-modern era.

    It is unknown which phenotype of polycystic ovary syndrome (PCOS) has a greater metabolic risk and how to detect this risk. The aim of this study was therefore to compare the incidence of metabolic syndrome (MetS) and metabolic risk profile (MRP) for different phenotypes. A total of 100 consecutive newly diagnosed PCOS women in a tertiary referral hospital were recruited. Patients were classified into four phenotypes according to the Rotterdam criteria, on the presence of at least two of the three criteria hyperandrogenism (H), oligo/anovulation (O) and PCO appearance (P): phenotype A, H + O + P; phenotype B, H + O; phenotype C, H + P; phenotype D, O + P. Prevalence of MetS and MRP were compared among the four groups. Based on Natural Cholesterol Education Program Adult Treatment Panel III diagnostic criteria, MetS prevalence was higher in phenotypes A and B (29.6% and 34.5%) compared with the other phenotypes (10.0% and 8.3%; P < 0.001). Although the prevalence of obesity was similar, the number of patients with homeostatic model assessment insulin resistance index (HOMA-IR) >3.8 was significantly higher in androgenic PCOS phenotypes. After logistic regression analysis, visceral adiposity index (VAI) was the only independent predictor of MetS in PCOS (P = 0.002). VAI was also significantly higher in phenotype B, when compared with the others (P < 0.01). Phenotypes A and B had the highest risk of MetS among the four phenotypes, and VAI may be a predictor of metabolic risk in PCOS women. © 2016 Japan Society of Obstetrics and Gynecology.

    Inflammatory and immune processes can be triggered in vitiligo due to a decreased number of melanocytes and their anti-inflammatory effects. Because of the systemic nature of vitiligo, metabolic abnormalities such as insulin resistance and lipid profile disturbances as well as skin involvement may be observed in vitiligo. To investigate the association between metabolic syndrome and vitiligo. Case-control study. The demographic, clinical and laboratory features in the subjects were compared according to presence of vitiligo and metabolic syndrome [patients (n=63) vs. gender-age matched controls (n=65) and metabolic syndrome positive (n=38) vs. negative (n=90)]. A logistic regression analysis was also used. We identified metabolic syndrome in 24 (38.1%) subjects with vitiligo and 14 (21.5%) subjects without vitiligo (p=0.04). Active vitiligo, segmental vitiligo, an increased duration of vitiligo and an increased percentage in the affected body surface area were determined to be independent predictors of metabolic syndrome [activity of vitiligo: p=0.012, OR (95% CI)=64.4 (2.5-1672); type of vitiligo: p=0.007, OR (95% CI)=215.1 (4.3-10725.8); duration of vitiligo: p=0.03, OR (95% CI)=1.4 (1.1-2.0); percentage of affected body surface area: p=0.07, OR (95% CI)=1.2 (0.98-1.5)]. The risk of developing metabolic syndrome is increased in patients with vitiligo. The poor clinical features of vitiligo, such as active, extended and segmental vitiligo with an increased duration of time, are independent predictors for developing metabolic syndrome.

    The term "metabolic syndrome" refers to the clustering of a number of cardiovascular risk factors (obesity, hypertension, dyslipidemia and hyperglycemia) believed to be related to insulin resistance. The prevalence of each of these diseases as well as the metabolic syndrome is increasing world wide. Obesity, hypertension, dyslipidemia and diabetes are no longer diseases of the wealthy. By 2025, three out of four people with diabetes will be living in 3rd world countries, and similar trends are likely for the other components of the syndrome. Preventive action is urgently needed, and studies in China and India have proven to be effective.

    Vitamin D deficiency and metabolic syndrome are 2 very common health problems in the Spanish population. It has been suggested that patients with metabolic syndrome may be vitamin D deficient more often than subjects without it and that low vitamin D levels may predispose to metabolic syndrome development. However, the results of prospective and intervention studies have been different and such relationship remains unclear. We assessed the relationship between 25-hydroxyvitamin D levels and the prevalence and incidence of metabolic syndrome. We undertook a population-based cohort study in Spain. At baseline (1996-1998), 1,226 subjects were evaluated. Follow-up visits were performed in 2002-2004 and 2005-2007.At baseline and follow-up, participants underwent an interview and a standardized clinical examination with an oral glucose tolerance test in those subjects without known diabetes. At the second visit, 25-hydroxyvitamin D levels and intact parathyroid hormone levels were measured. The prevalence of metabolic syndrome at the second and third visit was 29.4 and 42.5%, respectively. Mean levels of 25-hydroxyvitamin D were lower in subjects with metabolic syndrome: 21.7 (6.21) vs 23.35 (6.29) ng/ml, P<.001.The prevalence of vitamin D deficiency (25-hydroxyvitamin D<20 ng/ml) at the second evaluation was 34.7%, with significant differences between subjects with and without metabolic syndrome(34.6 vs 26.5%, P<.01). Men with vitamin D deficiency had more frequently hypertension and metabolic syndrome than men with normal levels. Women with vitamin D deficiency had more frequently hyperglycemia, hypertension, increased waist circumference and hypertriglyceridemia. In a prospective study, 25-hydroxyvitamin D values<20 ng/ml were not significantly associated with an increased risk of developing metabolic syndrome in the next 5 years (odds ratio 0,99, 95% confidence interval 0.57-1.7, P=.97) after adjusting by sex and age.

    The metabolic syndrome is thought to be associated with a chronic low-grade inflammation, and a growing body of evidence suggests that interleukin-18 (IL-18) might be closely related to the metabolic syndrome and its consequences. Circulating levels of IL-18 have been reported to be elevated in subjects with the metabolic syndrome, to be closely associated with the components of the syndrome, to predict cardiovascular events and mortality in populations with the metabolic syndrome and to precede the development of type 2 diabetes. IL-18 is found in the unstable atherosclerotic plaque, in adipose tissue and in muscle tissue, and is subject to several regulatory steps including cleavage by caspase-1, inactivation by IL-18 binding protein and the influence of other cytokines in modulating its interaction with the IL-18 receptor. The purpose of this review is to outline the role of IL-18 in the metabolic syndrome, with particular emphasis on cardiovascular risk and the potential effect of life style interventions.

The electrolyte imbalance is frequently detected in critical ill patients. It is reported that the extreme abnormalities of ionized calcium concentrations are independent predictors of mortality. In addition, from clinical database MIMIC-Ⅱ,calcium supplementation improves clinical outcome in intensive care unit patients. Although metabolic syndrome; lifestyle-related disease, is a chronic disease, the possibility of falling into acute disease by having it becomes very high and improvement of electrolyte imbalance, especially hypocalcaemia is expected to effective on clinical outcome.

    Tourette syndrome is a heritable neurodevelopmental disorder whose pathophysiology remains unknown. Recent genome-wide association studies suggest that it is a polygenic disorder influenced by many genes of small effect. We tested whether these genes cluster in cellular function by applying gene-set analysis using expert curated sets of brain-expressed genes in the current largest available Tourette syndrome genome-wide association data set, involving 1285 cases and 4964 controls. The gene sets included specific synaptic, astrocytic, oligodendrocyte and microglial functions. We report association of Tourette syndrome with a set of genes involved in astrocyte function, specifically in astrocyte carbohydrate metabolism. This association is driven primarily by a subset of 33 genes involved in glycolysis and glutamate metabolism through which astrocytes support synaptic function. Our results indicate for the first time that the process of astrocyte-neuron metabolic coupling may be an important contributor to Tourette syndrome pathogenesis. PMID:25735483

    The clustering of cardiovascular risk factors associated with abdominal obesity is well established. Although currently lacking a universal definition, the metabolic syndrome describes a constellation of metabolic abnormalities, including abdominal obesity, and was originally introduced to characterize a population at high cardiovascular risk. Adipose tissue is a dynamic endocrine organ that secretes several inflammatory and immune mediators known as adipokines. Dysregulation of adipokine secretion, free fatty acid toxicity, and the site-specific differences in abdominal (visceral) versus subcutaneous fat support abdominal obesity as a causal factor mediating the insulin resistance, increased risk of diabetes, and cardiovascular disease in the metabolic syndrome.

    Obesity is associated with premature atherosclerosis, as well as with many metabolic alterations including insulin resistance, dyslipidemia and hypertension. Visceral fat accumulation, particularly, is closely associated with the development of metabolic syndrome. The menopause transition, as well as the early postmenopausal period, is associated with increase in total and central obesity. Among adipocytokines secreted by the adipose tissue adiponectin is the only one that has a protective role in the development of obesity-related disorders, such as type 2 diabetes and cardiovascular disease. This review aims to present a role that adiponectin may play during the progress of menopause in relation to development of menopausal metabolic syndrome. PMID:27683315

    Summary Impaired insulin signaling is central to the development of the metabolic syndrome and can promote cardiovascular disease indirectly through development of abnormal glucose and lipid metabolism, hypertension and a proinflammatory state. However, insulin action directly on vascular endothelium, atherosclerotic plaque macrophages, and in the heart, kidney, and retina has now been described, and impaired insulin signaling in these locations can alter progression of cardiovascular disease in the metabolic syndrome and affect development of microvascular complications of diabetes. Recent advances in our understanding of the complex pathophysiology of insulin’s effects on vascular tissues offer new opportunities for preventing these cardiovascular disorders. PMID:22895666

    To investigate the relationship between physical activity and metabolic syndrome (MS). A multi-stage stratified cluster sampling was conducted in 132 sampling 218,920 residents, aged 44.3 +/- 15.3 (15 - 96), in the 31 provinces, autonomous regions, and municipalities of the mainland China according to the program of the National Nutrition and Health Survey. Questionnaire survey, interview, physical examination, measurement of biochemical indices, and dietary investigation were done. Information of physical activity and measurement of fasting glucose and/or glucose 2 hours after meal, blood pressure, triglycerides, high-density lipoprotein cholesterol were obtained in 50,494 participants. Metabolic syndrome was defined according to the Chinese Medical Association's definition. The intensity of physical activity was divided into 3 categories according to the Center for Disease Control and Prevention of US/American College of Sports Medicine criteria. 50,495 subjects, 23,932 males (47.4%) and 26,562 females (52.6%), were diagnosed as with MS. The MS incidence of those with high intensity of physical activity was lower by 60% in comparison with those with low intensity of physical activity (odds ratio 0.60, 95% CI: 0.362 - 0.443) adjusted for age, sex, smoking, and alcohol intake. The risk of MS in those with moderate intensity of physical activity of 151 - 300 minutes/week was slightly decreased compared to those with moderate intensity of physical activity of 90 - 150 minutes/week, (odds ratio 0.935, 95% CI: 0.685 - 1.277), however, the risk of MS in those with the moderate intensity of physical activity over 300 minutes/week increased slightly (OR = 1.269, 95% CI: 0.923 - 1.745). The risk of MS in those with low-level physical activity of 301 - 420 minutes/week was lower by 35% in comparison with those with the low-level physical activity of 90 - 150 minutes/week (95% CI: 0.451 - 0.933), however, the risk of MS in those with the low-level physical activity over 420

    The prevalence of metabolic disturbances, collectively known as metabolic syndrome, has reached an epidemic proportion in industrialized countries. Lifestyle interventions and pharmacological treatments of such pathologies are only partially efficient and new therapeutic approaches are urgently needed. This review focuses on the recent findings describing the regulatory functions of peroxisome proliferator-activated receptor beta (PPARbeta) on lipid metabolism in several tissues and on the implications of such findings on the therapeutic usefulness of PPARbeta agonists in the treatment of particular features of the metabolic syndrome, such as insulin resistance, obesity, dyslipidemia and cardiac dysfunctions.

    Zinc (Zn) is an essential mineral that is required for various cellular functions. Zn dyshomeostasis always is related to certain disorders such as metabolic syndrome, diabetes and diabetic complications. The associations of Zn with metabolic syndrome, diabetes and diabetic complications, thus, stem from the multiple roles of Zn: (1) a constructive component of many important enzymes or proteins, (2) a requirement for insulin storage and secretion, (3) a direct or indirect antioxidant action, and (4) an insulin-like action. However, whether there is a clear cause-and-effect relationship of Zn with metabolic syndrome, diabetes, or diabetic complications remains unclear. In fact, it is known that Zn deficiency is a common phenomenon in diabetic patients. Chronic low intake of Zn was associated with the increased risk of diabetes and diabetes also impairs Zn metabolism. Theoretically Zn supplementation should prevent the metabolic syndrome, diabetes, and diabetic complications; however, limited available data are not always supportive of the above notion. Therefore, this review has tried to summarize these pieces of available information, possible mechanisms by which Zn prevents the metabolic syndrome, diabetes, and diabetic complications. In the final part, what are the current issues for Zn supplementation were also discussed.

    Diets have been believed to be an important factor in the development of metabolic syndrome and colorectal cancer (CRC). In recent years, many studies have shown an intimate relationship between mucosal immunity, metabolism and diets, which has led to a greater understanding of the pathophysiology of metabolic syndrome and CRC development. Although the precise effects of diets on oncogenesis have not been compl-etely elucidated, microbiota changes and inflammation are believed to be important factors that influence the development of CRC. Moreover, increased release of pro-inflammatory cytokines and alteration of adipokine levels have been observed in patients with colorectal adenoma and/or CRC, and these all have been considered as the important mechanisms that link diets to the development of metabolic syndrome and CRC. Importantly, a high-fat, low-fiber diet is associated with dysbiosis, and as the gut signature becomes more important in metabolic syndrome and CRC, an increased understanding of diets on bacterial activity in the pathogenesis of metabolic syndrome and CRC will lead to new preventive and therapeutic strategies.

    Hyperuricemia has been described as associated with the risk of development metabolic syndrome; however the relationship between the uric acid level and particular parameters of metabolic syndrome remained unclear. We performed a cross-sectional study on a cohort of 833 dyslipidemic patients and correlated their levels of uric acid with parameters of insulin resistance, lipid metabolism, C-reactive protein, anthropometric parameters. We also defined patients with hypertriglyceridemic waist phenotype and compered their uric acid levels with those without this phenotype. We found that levels of uric acid are associated with parameters of metabolic syndrome. Specifically, dyslipidemia characteristic for metabolic syndrome (low HDL-cholesterol and high triglycerides) correlates better with uric acid levels than parameters of insulin resistance. Also waist circumference correlates better with uric acid levels than body mass index. Patients with hypertriglyceridemic waist phenotype had higher levels of uric acid when compared with patients without this phenotype. Serum uric acid levels are even in low levels linearly correlated with parameters of metabolic syndrome (better with typical lipid characteristics than with parameters of insulin resistance) and could be associated with higher cardiovascular risk.

    The detection of metabolic syndrome (MS) is use ful for identifying individuals at risk for type 2 diabetes and coronary heart disease. The objectives of the study were to describe the prevalence of MS in employees 40-65 years old, utilizing different definitions and to analyze the relation with educational level and gender by means of cross-sectional and multicenter study of different regions of Argentina. Compared MS definitions were: International Diabetes Federation, American Heart Association/National Heart, Lung and Blood Institute and National Cholesterol Education Program - Adults Treatment Panel III. Fulfilled the protocol 2806 cases. It was observed a prevalence of 0.31, 0.30 and 0.26 respectively, more frequent in men (p = 0.0000). There was no significant difference between sexes in the group 60 to 65 years old. After adjusting to age, sex, physical activity, family history of diabetes and menopause, the women with low educational level (<12 years) had more risk than men, OR = 1.95 (CI 95% 1.49-2.55) p = 0.000 compared with OR = 1.36 (CI 95% 1.10-1.69) p = 0.005, respectively. The low educational level in women, adjusted for confounders, was a predictor of four components of MS: central obesity, low C-HDL, glucose > or =100 mg/dl and hypertriglyceridemia; in men was only a hard predictor of hypertriglyceridemia. The results alert about the need of education of the population for the control of risk factors and adoption of healthy habits.

    Metabolic syndrome is a constellation of risk factors with increased predilection towards occurrence of cardiovascular diseases. Currently physical exercise and management with metformin are the prevailing treatment modalities for metabolic syndrome. Patients with metabolic syndrome have been found to have reduced exercise capacity over a period of time. Likewise metformin has been shown to decrease exercise capacity among healthy volunteers. Hence this study aims to evaluate the effect of metformin on the exercise capacity of patients with metabolic syndrome. Prospective study with 6 weeks follow up. Newly diagnosed patients with metabolic syndrome and to be started on Table Metformin 500mg twice a day were recruited for the study after obtaining written informed consent. Cardiopulmonary Exercise Testing (CPET) was done at baseline before the subjects were started on metformin and after 6 weeks of treatment using cardiopulmonary exercise testing apparatus (ZAN600). Fifteen treatment naïve patients with metabolic syndrome completed six weeks of therapy with metformin. In these patients oxygen uptake [VO2] showed statistically significant decrease from 1.10±0.44 at baseline to 0.9±0.39 (l/min) after six weeks of treatment with metformin [mean difference of -0.20 (-0.31 to -0.09); P=0.001]. Similarly oxygen uptake/kg body weight [VO2/Kg] showed a significant decrease from 14.10±4.73 to 11.44±3.81 (mlkg(-1)min(-1)) at the end of six weeks of treatment [mean difference of -2.66 (-4.06 to -1.26); P=0.001]. Six weeks of treatment with metformin significantly decreases exercise capacity in newly diagnosed patients with metabolic syndrome. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

    The metabolic syndrome is a condition characterized by a special constellation of reversible major risk factors for cardiovascular disease and type 2 diabetes. The main, diagnostic, components are reduced HDL-cholesterol, raised triglycerides, blood pressure and fasting plasma glucose, all of which are related to weight gain, specifically intra-abdominal/ectopic fat accumulation and a large waist circumference. Using internationally adopted arbitrary cut-off values for waist circumference, having metabolic syndrome doubles the risk of cardiovascular disease, but offers an effective treatment approach through weight management. Metabolic syndrome now affects 30-40% of people by age 65, driven mainly by adult weight gain, and by a genetic or epigenetic predisposition to intra-abdominal/ectopic fat accumulation related to poor intra-uterine growth. Metabolic syndrome is also promoted by a lack of subcutaneous adipose tissue, low skeletal muscle mass and anti-retroviral drugs. Reducing weight by 5-10%, by diet and exercise, with or without, anti-obesity drugs, substantially lowers all metabolic syndrome components, and risk of type 2 diabetes and cardiovascular disease. Other cardiovascular disease risk factors such as smoking should be corrected as a priority. Anti-diabetic agents which improve insulin resistance and reduce blood pressure, lipids and weight should be preferred for diabetic patients with metabolic syndrome. Bariatric surgery offers an alternative treatment for those with BMI ≥ 40 or 35-40 kg/m(2) with other significant co-morbidity. The prevalence of the metabolic syndrome and cardiovascular disease is expected to rise along with the global obesity epidemic: greater emphasis should be given to effective early weight-management to reduce risk in pre-symptomatic individuals with large waists.

    Objective: To verify the prevalence of metabolic syndrome and insulin resistance in obese adolescents and its relationship with different body composition indicators. Methods: A cross-sectional study comprising 79 adolescents aged ten to 18 years old. The assessed body composition indicators were: body mass index (BMI), body fat percentage, abdominal circumference, and subcutaneous fat. The metabolic syndrome was diagnosed according to the criteria proposed by Cook et al. The insulin resistance was determined by the Homeostasis Model Assessment for Insulin Resistance (HOMA-IR) index for values above 3.16. The analysis of ROC curves was used to assess the BMI and the abdominal circumference, aiming to identify the subjects with metabolic syndrome and insulin resistance. The cutoff point corresponded to the percentage above the reference value used to diagnose obesity. Results: The metabolic syndrome was diagnosed in 45.5% of the patients and insulin resistance, in 29.1%. Insulin resistance showed association with HDL-cholesterol (p=0.032) and with metabolic syndrome (p=0.006). All body composition indicators were correlated with insulin resistance (p<0.01). In relation to the cutoff point evaluation, the values of 23.5 and 36.3% above the BMI reference point allowed the identification of insulin resistance and metabolic syndrome. The best cutoff point for abdominal circumference to identify insulin resistance was 40%. Conclusions: All body composition indicators, HDL-cholesterol and metabolic syndrome showed correlation with insulin resistance. The BMI was the most effective anthropometric indicator to identify insulin resistance. PMID:24676191

    OBJECTIVES: We investigated the relationship between metabolic syndrome and breast arterial calcification detected via mammography in a cohort of postmenopausal subjects. METHODS: Among 837 patients referred to our radiology department for mammographic screening, 310 postmenopausal females (105 patients with and 205 patients without breast arterial calcification) aged 40 to 73 (mean 55.9±8.4) years were included in this study. The groups were compared with respect to clinical characteristics and metabolic syndrome criteria. Univariate and multivariate analyses identified the factors related to breast arterial calcification. RESULTS: Age, postmenopausal duration and the frequencies of diabetes mellitus, hypertension and metabolic syndrome were significantly higher in the subjects with breast arterial calcification than in those without (p<0.05). Multivariate analysis indicated that age (OR = 1.3, 95% CI = 1.1–1.6, p = 0.001) and metabolic syndrome (OR = 4.0, 95% CI = 1.5−10.4, p = 0.005) were independent predictors of breast arterial calcification detected via mammography. The independent predictors among the features of metabolic syndrome were low levels of high-density lipoproteins (OR = 8.1, 95% CI = 1.0−64.0, p = 0.047) and high blood pressure (OR = 8.7, 95% CI = 1.5−49.7, p = 0.014). CONCLUSIONS: The likelihood of mammographic detection of breast arterial calcification increases with age and in the presence of hypertension or metabolic syndrome. For patients undergoing screening mammography who present with breast arterial calcification, the possibility of metabolic syndrome should be considered. These patients should be informed of their cardiovascular risk factors and counseled on appropriate lifestyle changes. PMID:25627997

Prospective, randomized, double-blind, placebo-controlled study. Outpatient general clinical research center. Thirty-two nondiabetic men and women with a clinical diagnosis of metabolic syndrome (as defined in the American Heart Association-National Heart, Lung, and Blood Institute scientific statement). Patients were randomly assigned to receive either oral rosiglitazone 4 mg/day or matching placebo for 12 weeks. The primary end point was change in serum adiponectin concentrations from baseline to week 12. Secondary end points were changes in serum resistin concentrations, insulin resistance, fasting glucose level, fasting insulin level, body weight, lipid levels, systolic and diastolic blood pressure, and waist circumference from baseline to week 12. Also, changes from baseline in adiponectin and resistin concentrations and insulin resistance were assessed over time at weeks 2, 4, 8, and 12. Rosiglitazone was associated with a significant increase in serum adiponectin concentration after 12 weeks compared with placebo (45.8% vs 2.6%, p=0.002). The increase in adiponectin concentration occurred quickly, with a significant difference observed after 2 weeks of therapy. Compared with placebo, rosiglitazone was not associated with significant 12-week changes in serum resistin concentrations, insulin resistance, fasting glucose level, fasting insulin level, body weight, lipid levels, systolic or diastolic blood pressure, or waist circumference. Rosiglitazone had beneficial effects on

    Objective The metabolic syndrome is associated with a high risk of diabetes and cardiovascular disease, and Hispanics in the United States have higher rates than do other ethnic groups. We assessed the prevalence of the metabolic syndrome and its individual components in Puerto Rican adults. Methods We conducted a cross-sectional study that used a probability cluster design to select a sample of households of the San Juan metropolitan area from 2005 through 2007. A total of 859 persons aged 21–79 years completed a face-to-face interview, blood pressure and waist circumference measurements, and blood sampling. Our primary outcome measure was metabolic syndrome as defined by the updated NCEP-ATP criteria. Results Prevalence of the metabolic syndrome was 43.3%; 45.3% for men and 42.2% for women (P>.05). Prevalence significantly rose with age, from 12.8% among participants aged 21–29 years to 58.2% for participants aged 70–79 years (P<.001). Corresponding increases in the prevalence of the metabolic syndrome in both men and women were also observed; the prevalence peaked in men aged 50–59 years (62.6%) and in women aged 70–79 years (65.2%). Elevated glucose (49.8%) and abdominal obesity (49.0%) were the most common components of the metabolic syndrome, followed by elevated blood pressure (46.1%), reduced high-density lipoprotein cholesterol (46.0%), and elevated triglycerides (31.3%). Substantial variations were found between men and women in the prevalence of individual components. Conclusions Puerto Ricans have a high prevalence of the metabolic syndrome. This health disparity has implications for diabetes and cardiovascular prevention programs. PMID:19157247

    The intimate interplay between immune system, metabolism, and gut microbiota plays an important role in controlling metabolic homeostasis and possible obesity development. Obesity involves impairment of immune response affecting both innate and adaptive immunity. The main factors involved in the relationship of obesity with inflammation have not been completely elucidated. On the other hand, gut microbiota, via innate immune receptors, has emerged as one of the key factors regulating events triggering acute inflammation associated with obesity and metabolic syndrome. Inflammatory disorders lead to several signaling transduction pathways activation, inflammatory cytokine, chemokine production and cell migration, which in turn cause metabolic dysfunction. Inflamed adipose tissue, with increased macrophages infiltration, is associated with impaired preadipocyte development and differentiation to mature adipose cells, leading to ectopic lipid accumulation and insulin resistance. This review focuses on the relationship between obesity and inflammation, which is essential to understand the pathological mechanisms governing metabolic syndrome. PMID:26635627

    We sought to explore to what extent the presence of cardiometabolic and cardiovascular risk constitutions differ between pregnancies complicated by small-for-gestational-age (SGA) infancy, preeclampsia (PE), or a combination of both. We conducted a cohort study in women after pregnancies complicated by placental syndrome with fetal manifestations (SGA infancy [n = 113]), maternal manifestations (PE [n = 729]), or both (n = 461). Independent sample t test was used to compare cardiometabolic and cardiovascular risk factors between groups. Logistic regression was used to calculate odds ratios and adjusted odds ratios of the prevalence of the metabolic syndrome and its constituents between groups. Adjustments were made for maternal age, parity, smoking, interval between delivery and measurements, and intrauterine fetal demise. The metabolic syndrome was present in 7.5% of women who delivered SGA infants, 15.6% of former PE women, and 19.8% of women after pregnancy complicated by both SGA and PE. Hypertension was observed in 25% of former PE women and 15% of women with solely SGA. Women who delivered a SGA infant had lower global vascular compliance compared to former PE women without SGA. Cardiometabolic risk factors consistent with metabolic syndrome relate to the maternal rather than to the fetal presentation of placental syndrome. Nonetheless, highest incidence of metabolic syndrome was observed in women with both PE and SGA. PE relates to chronic hypertension, whereas increased arterial stiffness seems to be associated with women who deliver a SGA infant. Copyright © 2015 Elsevier Inc. All rights reserved.

  6. Genetic selection of embryos that later develop the metabolic syndrome.

    THE BARKER HYPOTHESIS: Is an excellent explanation of the process where human and animal foetuses exposed to malnutrition, either by maternal malnutrition or placental insufficiency, are metabolically programmed, with selective stunting of cell differentiation and organ growth. With the postnatal excess of nutrition observed in developed countries, this irreversible programming causes metabolic syndrome, including obesity, type 2 diabetes, and hypertension. Metabolic programming involves epigenetic changes including imprinting which might be transmitted through more than one generation rather than being completely re-set or erased during reproduction. The Barker hypothesis was supported by epidemiological data that recognised no excess fetal or postnatal mortality when pregnant women were starved during the Dutch famine in World War II. This argued against the "thrifty genotype" theory introduced in 1962, which proposed that starvation selected against members of the population with less "thrifty" genes, but the survivors who had "thrifty" genes developed metabolic syndrome if they were subsequently over-nourished. EMBRYONIC/FETAL SELECTION: Embryos or early foetuses could be selected very early in pregnancy on the basis of their genotype, by maternal malnutrition, hypertension, obesity or other causes of placental insufficiency. The genotype that allows embryos, or cells within them, to survive a less hospitable environment in the decidua after implantation might contribute to the later development of metabolic syndrome. This article hypothesises that an adverse intrauterine environment, caused by maternal malnutrition or placental insufficiency, kills a proportion of embryos and selects a surviving population of early embryos whose growth in utero is retarded by their genotype, their environment or a combination of both. The metabolic syndrome follows if the offspring is over-nourished later in life. The embryonic selection hypothesis presented here could be

    To explore the association between cardiovascular fitness and metabolic syndrome across occupational groups using a nationally representative sample of the US population. Respondents aged 18 to 49 years from the 1999 to 2004 National Health and Nutrition Examination Survey were evaluated for cardiovascular fitness and classified with regard to metabolic syndrome. Comparisons were made across 40 occupational categories. For all occupations with and without metabolic syndrome, the estimated maximal oxygen consumption (VO2max) was 38.8 mL/kg/min (standard error = 0.5) and 41.1 mL/kg/min (standard error = 0.2), respectively. The estimated VO2max was higher for those without metabolic syndrome for most occupational groups, particularly for sales supervisors and proprietors, sales representatives, finance, business, and commodities, and freight, stock, and material movers. Low estimated VO2max among workers with metabolic syndrome can be addressed, in part, by workplace interventions designed to increase fitness. This study identifies priority occupational groups for these interventions.

Forty-five women with no past medical history were studied in this cross-sectional study at the Department of Endocrinology, Medwin Hospitals, Hyderabad, India, from August 2008 to September 2008. The body fat was estimated using bio-impedance method, and fasting blood sample was analyzed for total triiodothyronine (T3), total thyroxine (T4), thyroid-stimulating hormone (TSH), free triiodothyronine (FT3), lipid profile, insulin, and glucose. The mean age of the participants was 32.6 +/= 9.6 years with a body mass index (BMI) of 29.9 +/= 3.8 kg/m2. Evidence of homeostasis model assessment index for insulin resistance (HOMA-IR) more than 3 was seen in 34 (75%) and metabolic syndrome in 29 (64%) participants. Total T3 showed a positive correlation with triglycerides, low density lipoprotein- cholesterol (LDL-C), total cholesterol, insulin, HOMA-IR and negatively with body fat. Thyroid-stimulating hormone correlated positively with BMI, insulin, HOMA-IR, LDL-C and negatively with HDL-cholesterol (p<0.05). Free triiodothyronine correlated positively with waist circumference and T4 did not correlate with metabolic syndrome parameters. Our preliminary data show an association between thyroid hormones and some components specific of the metabolic syndrome in euthyroid women. Total triiodothyronine and TSH correlated more with variables of metabolic syndrome than FT3 and T4.

    Metabolic syndrome, with its increasing prevalence, is becoming a major public health problem throughout the world. Many risk factors including nutrition play a role in the emergence of metabolic syndrome. Of the most-consumed beverages in the world, coffee contains more than 1000 components such as caffeine, chlorogenic acid, diterpenes and trigonelline. It has been proven in many studies that coffee consumption has a positive effect on chronic diseases. In this review, starting from the beneficial effects of coffee on health, the relationship between coffee consumption and metabolic syndrome and its components has been investigated. There are few studies investigating the relationship between coffee and metabolic syndrome, and the existing ones put forward different findings. The factors leading to the differences are thought to stem from coffee variety, the physiological effects of coffee elements, and the nutritional ingredients (such as milk and sugar) added to coffee. It is reported that consumption of coffee in adults up to three cups a day reduces the risk of Type-2 diabetes and metabolic syndrome.

    The body's total antioxidant capacity represents a sum of the antioxidant capacity of various tissues/organs. A decrease in the body's antioxidant capacity may induce oxidative stress and subsequent metabolic syndrome, a clustering of risk factors for type 2 diabetes and cardiovascular disease. The skin, the largest organ of the body, is one of the major components of the body's total antioxidant defense system, primarily through its xenobiotic/drug biotransformation system, reactive oxygen species-scavenging system, and sweat glands- and sebaceous glands-mediated excretion system. Notably, unlike other contributors, the skin contribution is variable, depending on lifestyles and ambient temperature or seasonal variations. Emerging evidence suggests that decreased skin's antioxidant and excretory functions (e.g., due to sedentary lifestyles and low ambient temperature) may increase the risk for metabolic syndrome. This review focuses on the relationship between the variability of skin-mediated detoxification and elimination of exogenous and endogenous toxic substances and the development of metabolic syndrome. The potential role of sebum secretion in lipid and cholesterol homeostasis and its impact on metabolic syndrome, and the association between skin disorders (acanthosis nigricans, acne, and burn) and metabolic syndrome are also discussed.

    In this review, we discuss the genetic architecture of obesity and the metabolic syndrome, highlighting recent advances in identifying genetic variants and loci responsible for a portion of the variation in adiposity traits, serum HDL and triglycerides, blood pressure, and glycemic traits; in other words, the components comprising the metabolic syndrome. We focus particularly on recent progress from large-scale genome-wide association studies. Detailing their successes and how lessons learned can pave the way for future discovery. Results from recent genome-wide association studies coalesce with earlier work suggesting numerous interconnections between obesity and the metabolic syndrome, developed through several potentially pleiotropic effects. We detail recent work by way of a case study on the cadherin 13 gene and its relation with adiponectin in the HyperGEN and the Framingham Heart Studies, and its association with obesity and the metabolic syndrome. We provide also a gene network analysis on recent variants related to obesity and metabolic syndrome discovered through genome-wide association studies. PMID:20406164

    Prevalence of alcohol consumption is high in the general population and generates specific problems at the workplace. To establish benchmarks between levels of alcohol consumption and cardiovascular risk variables and metabolic syndrome. A cross-sectional study of 7,644 workers of Spanish companies (2,828 females and 4,816 males). Alcohol consumption and its relation to cardiovascular risk was assessed using Framingham calibrated for the Spanish population (REGICOR) and SCORE, and metabolic syndrome was assessed using modified ATPIII and IDF criteria and Castelli and atherogenic index and triglycerides/HDL ratio. A multivariate analysis was performed using logistic regression and odds ratios were estimated. Statistically significant differences were seen in the mean values of the different parameters studied in prevalence of metabolic syndrome, for both sexes and with modified ATPIII, IDF and REGICOR and SCORE. The sex, age, alcohol, and smoking variables were associated to cardiovascular risk parameters and metabolic syndrome. Physical exercise and stress are only associated to with some of them. The alcohol consumption affects all cardiovascular risk parameters and metabolic syndrome, being more negative the result in high level drinkers. Copyright © 2014 SEEN.

    aim: To know the metabolic syndrome and its components prevalence in Mexico City adolescents sample. A cross-sectional survey was conducted in 772 men and 1078 women, 12 to 16 years old, from 8 randomly selected public junior high schools in Mexico City. Anthropometric variables, lipids, lipoproteins, Apo AI and B, glucose and insulin were determined. Prevalence of metabolic syndrome was 12.5%, 11.15% in men and 13.5% en women (p ns). The most frequently metabolic syndrome component found in México City adolescents was low HDL-C levels (38%), followed by hypertriglyceridemia (25.5%), hypertension (19.2%), central obesity (11.8%) and elevated fasting glucose (1.7). Except by the hypertriglyceridemia, higher in woman than in men, 28.2% vs. 21.6%, p < 0.001, the prevalence of metabolic syndrome components was similar between males and females. The high prevalence of biochemical and physiological factors of metabolic syndrome, associated with overweight and obesity in Mexico City adolescents, increases the risk of premature development of coronary atherosclerosis and diabetes mellitus in this population.

    The present review provides an update of the biological actions of Pycnogenol® in the treatment of metabolic syndrome and related disorders such as obesity, dyslipidaemia, diabetes and hypertension. Pycnogenol® is a French maritime pine bark extract produced from the outer bark of Pinus pinaster Ait. Subsp. atlantica. Its strong antioxidant, antiinflammatory, endothelium-dependent vasodilator activity, and also its anti-thrombotic effects make it appropriate for targeting the multifaceted pathophysiology of metabolic syndrome. Clinical studies have shown that it can reduce blood glucose levels in people with diabetes, blood pressure in mild to moderate hypertensive patients, and waist circumference, and improve lipid profile, renal and endothelial functions in metabolic syndrome. This review highlights the pathophysiology of metabolic syndrome and related clinical research findings on the safety and efficacy of Pycnogenol®. The results of clinical research studies performed with Pycnogenol® are discussed using an evidence-based, target-oriented approach following the pathophysiology of individual components as well as in metabolic syndrome overall.

    2012-01-01

    The body’s total antioxidant capacity represents a sum of the antioxidant capacity of various tissues/organs. A decrease in the body’s antioxidant capacity may induce oxidative stress and subsequent metabolic syndrome, a clustering of risk factors for type 2 diabetes and cardiovascular disease. The skin, the largest organ of the body, is one of the major components of the body’s total antioxidant defense system, primarily through its xenobiotic/drug biotransformation system, reactive oxygen species-scavenging system, and sweat glands- and sebaceous glands-mediated excretion system. Notably, unlike other contributors, the skin contribution is variable, depending on lifestyles and ambient temperature or seasonal variations. Emerging evidence suggests that decreased skin’s antioxidant and excretory functions (e.g., due to sedentary lifestyles and low ambient temperature) may increase the risk for metabolic syndrome. This review focuses on the relationship between the variability of skin-mediated detoxification and elimination of exogenous and endogenous toxic substances and the development of metabolic syndrome. The potential role of sebum secretion in lipid and cholesterol homeostasis and its impact on metabolic syndrome, and the association between skin disorders (acanthosis nigricans, acne, and burn) and metabolic syndrome are also discussed.

    ABSTRACT Objectives: to present currently available evidence to verify the association between metabolic syndrome and quality of life. Method: Cochrane Library, EMBASE, Medline and LILACS databases were studied for all studies investigating the association with metabolic syndrome and quality of life. Two blinded reviewers extracted data and one more was chosen in case of doubt. Results: a total of 30 studies were included, considering inclusion and exclusion criteria, which involved 62.063 patients. Almost all studies suggested that metabolic syndrome is significantly associated with impaired quality of life. Some, however, found association only in women, or only if associated with depression or Body Mass Index. Merely one study did not find association after adjusted for confounding factors. Conclusion: although there are a few studies available about the relationship between metabolic syndrome and quality of life, a growing body of evidence has shown significant association between metabolic syndrome and the worsening of quality of life. However, it is necessary to carry out further longitudinal studies to confirm this association and verify whether this relationship is linear, or only an association factor. PMID:27901223

    Civilization development is associated with immense progress in science and significant improvement of human living conditions but simultaneously it contributes to many health problems including metabolic syndrome. Metabolic syndrome is a set of mutually associated factors including insulin resistance, hyperinsulinemia, obesity, lipids disorders and hypertension, which is the main cause of development of coronary heart disease and type 2 diabetes. The first line of defense against metabolic syndrome is a change of life style including body mass reduction, application of a low-calorie diet and performance of physical activity. In spite of the simplicity of therapy, long-term success of the above treatment among patients is observed seldom because it is very difficult to obey rigorous rules. Nowadays, it is considered that diet supplements including antioxidants, polyunsaturated fatty acids and mineral elements are helpful in metabolic syndrome treatment due to their antioxidant and anti-inflammatory properties. It is considered that a health balanced diet enriched with various diet supplements may be the best strategy in metabolic syndrome treatment.

    Dravet syndrome (DS) is a rare genetic epilepsy syndrome which is particularly pharmacoresistant. Vagus nerve stimulation (VNS) is commonly used in the treatment of DS as an adjunct to medical therapy. A meaningful assessment of post-surgical outcomes with VNS is difficult given the rarity of the condition. In a novel approach, we used social media to contact patients with DS to gather data on post-surgical seizure reduction and overall satisfaction with VNS. A survey consisting of 10 questions was posted to a social media webpage for a DS support group moderated by the Dravet Syndrome Foundation. The results were analyzed and percentages reported using the integrated SurveyMonkey analytical software. 49 responses were received. We found that 28.5% of patients had a >50% reduction in seizure frequency after VNS placement, 55.8% felt that VNS therapy had helped to reduce seizure frequency, and 83.7% felt that seizure severity had improved. Of the respondents, 75% felt that they would undergo VNS implantation again for similar outcomes. We employed the novel technique of using social media to gather the largest set of self-reported outcomes of VNS therapy for Dravet syndrome. As corroborated by prior studies of VNS effectiveness in Dravet syndrome, there is significant albeit limited improvement in seizure control. Our study shows that despite this limitation, it is still considered a useful treatment adjunct from a caregiver's perspective. Copyright © 2017 Elsevier B.V. All rights reserved.

    The real promise of the metabolic syndrome concept was the opportunity to elucidate a singular common mechanism for its component abnormalities and consequently a singular therapy. That promise has not produced. This relates to the following considerations: (1) metabolic syndrome remains a syndrome not a disease, (2) its diagnosis offers little more than what can be determined by measuring waist circumference, (3) risk assessment is not improved by the diagnosis of metabolic syndrome, (4) the diagnosis of metabolic syndrome does not impact the treatment of each component of the syndrome, and (5) there is no effective therapy for metabolic syndrome in its entirety.

    OBJECTIVE This study examined the association between objectively measured sedentary activity and metabolic syndrome among older adults. RESEARCH DESIGN AND METHODS Data were from 1,367 men and women, aged ≥60 years who participated in the 2003–2006 National Health and Nutrition Examination Survey (NHANES). Sedentary time during waking hours was measured by an accelerometer (<100 counts per minute). A sedentary bout was defined as a period of time >5 min. A sedentary break was defined as an interruption in sedentary time (≥100 counts per minute). Metabolic syndrome was defined according to the Adult Treatment Panel (ATP) III criteria. RESULTS On average, people spent 9.5 h (65% of wear time) as sedentary. Compared with people without metabolic syndrome, people with metabolic syndrome spent a greater percentage of time as sedentary (67.3 vs. 62.2%), had longer average sedentary bouts (17.7 vs. 16.7 min), had lower intensity during sedentary time (14.8 vs. 15.8 average counts per minute), and had fewer sedentary breaks (82.3 vs. 86.7), adjusted for age and sex (all P < 0.01). A higher percentage of time sedentary and fewer sedentary breaks were associated with a significantly greater likelihood of metabolic syndrome after adjustment for age, sex, ethnicity, education, alcohol consumption, smoking, BMI, diabetes, heart disease, and physical activity. The association between intensity during sedentary time and metabolic syndrome was borderline significant. CONCLUSIONS The proportion of sedentary time was strongly related to metabolic risk, independent of physical activity. Current results suggest older people may benefit from reducing total sedentary time and avoiding prolonged periods of sedentary time by increasing the number of breaks during sedentary time.

    The polydactylous rat strain (PD/Cub) is a highly inbred (F > 90) genetic model of metabolic syndrome. The aim of this study was to analyze the genetic architecture of the metabolic derangements found in the PD/Cub strain and to assess its dynamics in time and in response to diet and medication. We derived a PD/Cub x BN/Cub (Brown Norway) F2 intercross population of 149 male rats and performed metabolic profiling and genotyping and multiple levels of genetic linkage and statistical analyses at five different stages of ontogenesis and after high-sucrose diet feeding and dexamethasone administration challenges. The interval mapping analysis of 83 metabolic and morphometric traits revealed over 50 regions genomewide with significant or suggestive linkage to one or more of the traits in the segregating PD/Cub x BN/Cub population. The multiple interval mapping showed that, in addition to "single" quantitative train loci, there are more than 30 pairs of loci across the whole genome significantly influencing the variation of particular traits in an epistatic fashion. This study represents the first whole genome analysis of metabolic syndrome in the PD/Cub model and reveals several new loci previously not connected to the genetics of insulin resistance and dyslipidemia. In addition, it attempts to present the concept of "dynamic genetic architecture" of metabolic syndrome attributes, evidenced by shifts in the genetic determination of syndrome features during ontogenesis and during adaptation to the dietary and pharmacological influences.

    Although white coat hypertension (WCH) is believed to have an effect on health, there is no term defining WCH in metabolic syndrome. Consecutive patients 20 years old or older who underwent a check-up were included. The study included 1068 cases. The prevalences of hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, impaired glucose tolerance (IGT), and WCH were similar to excess weight in that they increased significantly until the seventh decade of life and decreased thereafter significantly (P < 0.05 in most steps). On the other hand, the prevalences of hypertension (HT), diabetes mellitus (DM), and coronary heart disease (CHD) always increased significantly with age without any decrease (P < 0.05 in most steps), indicating their irreversibility in contrast to the reversibility of excess weight, hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, IGT, and WCH. Metabolic syndrome is a reversible progression step between health and irreversible final diseases terminating with increased mortality and disabilities. Thus, the definition of metabolic syndrome should include reversible metabolic risk factors such as excess weight (overweight and obesity), hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, IGT, and WCH, instead of irrevesible diseases such as DM, HT, CHD, and stroke that have already developed and require drug therapy. After development of one of the final metabolic diseases, the term metabolic syndrome probably loses most of its significance, since from that point on, nonpharmaceutical approaches such as lifestyle changes, diet, and exercise will provide little benefit to prevent development of the others, most likely due to the cumulative effects of the risk factors on body systems over a long period of time.

    ABSTRACT OBJECTIVE To determine the prevalence of metabolic syndrome and its components in Brazilian adolescents. METHODS We evaluated 37,504 adolescents who were participants in the Study of Cardiovascular Risks in Adolescents (ERICA), a cross-sectional, school-based, national study. The adolescents, aged from 12 to 17 years, lived in cities with populations greater than 100,000 inhabitants. The sample was stratified and clustered into schools and classes. The criteria set out by the International Diabetes Federation were used to define metabolic syndrome. Prevalences of metabolic syndrome were estimated according to sex, age group, school type and nutritional status. RESULTS Of the 37,504 adolescents who were evaluated: 50.2% were female; 54.3% were aged from 15 to 17 years, and 73.3% were from public schools. The prevalence of metabolic syndrome was 2.6% (95%CI 2.3-2.9), slightly higher in males and in those aged from 15 to 17 years in most macro-regions. The prevalence was the highest in residents from the South macro-region, in the younger female adolescents and in the older male adolescents. The prevalence was higher in public schools (2.8% [95%CI 2.4-3.2]), when compared with private schools (1.9% [95%CI 1.4-2.4]) and higher in obese adolescents when compared with nonobese ones. The most common combinations of components, referring to 3/4 of combinations, were: enlarged waist circumference (WC), low HDL-cholesterol (HDL-c) and high blood pressure; followed by enlarged WC, low HDL-c and high triglycerides; and enlarged WC, low HDL-c, high triglycerides and blood pressure. Low HDL was the second most frequent component, but the highest prevalence of metabolic syndrome (26.8%) was observed in the presence of high triglycerides. CONCLUSIONS ERICA is the first Brazilian nation-wide study to present the prevalence of metabolic syndrome and describe the role of its components. Despite the prevalence of Metabolic Syndrome being low, the high prevalences of some

    Prevention of the metabolic syndrome and treatment of its main characteristics are now considered of utmost importance in order to combat the epidemic of type 2 diabetes mellitus and to reduce the increased risk of cardiovascular disease and all-cause mortality. Insulin resistance/hyperinsulinaemia are consistently linked with a clustering of multiple clinical and subclinical metabolic risk factors. It is now widely recognised that obesity (especially abdominal fat accumulation), hyperglycaemia, dyslipidaemia and hypertension are common metabolic traits that, concurrently, constitute the distinctive insulin resistance or metabolic syndrome. Cross-sectional and prospective data provide an emerging picture of associations of both physical activity habits and cardiorespiratory fitness with the metabolic syndrome. The metabolic syndrome, is a disorder that requires aggressive multi-factorial intervention. Recent treatment guidelines have emphasised the clinical utility of diagnosis and an important treatment role for 'therapeutic lifestyle change', incorporating moderate physical activity. Several previous narrative reviews have considered exercise training as an effective treatment for insulin resistance and other components of the syndrome. However, the evidence cited has been less consistent for exercise training effects on several metabolic syndrome variables, unless combined with appropriate dietary modifications to achieve weight loss. Recently published randomised controlled trial data concerning the effects of exercise training on separate metabolic syndrome traits are evaluated within this review. Novel systematic review and meta-analysis evidence is presented indicating that supervised, long-term, moderate to moderately vigorous intensity exercise training, in the absence of therapeutic weight loss, improves the dyslipidaemic profile by raising high density lipoprotein-cholesterol and lowering triglycerides in overweight and obese adults with characteristics

    Metabolic syndrome--a cluster of metabolic diseases and hypertension--is not a new disease. It has been present in the upper classes of all highly developed cultures suffering from over-nutrition and limited physical activity. In the medical literature, it can be found in Renaissance and Baroque times. We are presently experiencing a global tsunami of this syndrome as over-nutrition and lack of movement are typical for large groups of the population. The current definition of metabolic syndrome of the American Heart Association/National Heart, Lung and Blood Institute and the International Diabetes Federation incorporates the quartet central obesity, hypertension, increased blood sugar and dyslipidemia (hypertriglyceridemia, low HDL cholesterol). Thus, simple, collective diagnostics and therapy for this finely meshed group of diseases together with its risk factors is possible.

    The evolution of the metabolic syndrome in afflicted individuals is, in part, characterized by the development of a severely pro-oxidant state within the vasculature. It has been previously demonstrated by many investigators that this increasingly pro-oxidant state can have severe negative implications for many relevant processes within the vasculature, including the coordination of dilator/constrictor tone or reactivity, the structural adaptations of the vascular wall or distal networks, as well as the integrated regulation of perfusion resistance across and throughout the vascular networks. The purpose of this review article is to present the different sources of oxidant stress within the setting of the metabolic syndrome, the available mechanism for attempts at regulation and the vascular outcomes associated with this condition. It is anticipated that this overview will help readers and investigators to more effectively design experiments and interpret their results within the extremely complicated setting of metabolic syndrome.

    Until just a few years ago, the genetic determinants of obesity and metabolic syndrome were largely unknown, with the exception of a few forms of monogenic extreme obesity. Since genome-wide association studies (GWAS) became available, large advances have been made. The first single nucleotide polymorphism robustly associated with increased body mass index (BMI) was in 2007 mapped to a gene with for the time unknown function. This gene, now known as fat mass and obesity associated (FTO) has been repeatedly replicated in several ethnicities and is affecting obesity by regulating appetite. Since the first report from a GWAS of obesity, an increasing number of markers have been shown to be associated with BMI, other measures of obesity or fat distribution and metabolic syndrome. This systematic review of obesity GWAS will summarize genome-wide significant findings for obesity and metabolic syndrome and briefly give a few suggestions of what is to be expected in the next few years.

    Treatment-related obesity and the metabolic syndrome in adult survivors of childhood acute lymphoblastic leukemia (ALL) are risk factors for cardiovascular disease. Both conditions often begin during therapy. Preventive measures, including dietary counseling and tailored exercise, should be initiated early in the course of survivorship, with referral to specialists to optimize success. However, among adults who develop obesity or the metabolic syndrome and who do not respond to lifestyle therapy, medical intervention may be indicated to manage underlying pathology, such as growth hormone deficiency, or to mitigate risk factors of cardiovascular disease. Because no specific clinical trials have been done in this population to treat metabolic syndrome or its components, clinicians who follow adult survivors of childhood ALL should use the existing American Heart Association/National Heart Lung and Blood Institute Scientific Statement to guide their approach.

    Insomnia has been reported to underlie the development and aggravation of metabolic syndrome including hypertension, cardiovascular disease, and diabetes. Treatment of insomnia is important for both the management and prevention of these comorbid disorders. We introduced the treatment strategy of insomnia for the patients with metabolic syndrome. For the better management of insomnia, sleep hygiene education should be given first, and adequate drug therapy should be started thereafter. Cognitive behavioral therapy is useful not only for insomnia symptom but also for the reducing amount of drug and prevention of the recurrence of insomnia. We expect that progress in the management of insomnia would result in the better treatment outcome of metabolic syndrome in general practice.

    Fructose is a commonly used sweetener associated with diets that increase the prevalence of metabolic syndrome. Thiazide diuretics are frequently used in these patients for treatment of hypertension, but they also exacerbate metabolic syndrome. Rats on high-fructose diets that are given thiazides exhibit potassium depletion and hyperuricemia. Potassium supplementation improves their insulin resistance and hypertension, whereas allopurinol reduces serum levels of uric acid and ameliorates hypertension, hypertriglyceridemia, hyperglycemia, and insulin resistance. Both potassium supplementation and treatment with allopurinol also increase urinary nitric oxide excretion. We suggest that potassium depletion and hyperuricemia in rats exacerbates endothelial dysfunction and lowers the bioavailability of nitric oxide, which blocks insulin activity and causes insulin resistance during thiazide usage. Addition of potassium supplements and allopurinol with thiazides might be helpful in the management of metabolic syndrome.

    Emerging science supports therapeutic roles of strawberries, blueberries, and cranberries in metabolic syndrome, a prediabetic state characterized by several cardiovascular risk factors. Interventional studies reported by our group and others have demonstrated the following effects: strawberries lowering total and LDL-cholesterol, but not triglycerides, and decreasing surrogate biomarkers of atherosclerosis (malondialdehyde and adhesion molecules); blueberries lowering systolic and diastolic blood pressure and lipid oxidation and improving insulin resistance; and low-calorie cranberry juice selectively decreasing biomarkers of lipid oxidation (oxidized LDL) and inflammation (adhesion molecules) in metabolic syndrome. Mechanistic studies further explain these observations as up-regulation of endothelial nitric oxide synthase activity, reduction in renal oxidative damage, and inhibition of the activity of carbohydrate digestive enzymes or angiotensin-converting enzyme by these berries. These findings need confirmation in future studies with a focus on the effects of strawberry, blueberry, or cranberry intervention in clinical biomarkers and molecular mechanisms underlying the metabolic syndrome.

    The aim of this study is to compare metabolic syndrome with syndrome Z growing epidemic in terms of risk factors, demographic variables, and gender differences in our large cohort at southeastern area in Turkey. Data of patients admitted to sleep clinic in University of Gaziantep from January 2006 to January 2011 were retrospectively evaluated. ATP III and JNC 7 were used for defining metabolic syndrome and hypertension. Data of 761 patients were evaluated. Hypertension, diabetes mellitus, coronary artery disease, pulmonary hypertension, and left ventricular hypertrophy were more common in patients with syndrome Z than in patients without metabolic syndrome. Age, waist/neck circumferences, BMI, triglyceride, glucose, and Epworth sleepiness scale score were detected higher, whereas the minimum oxygen saturation during sleep was lower in patients with syndrome Z. Metabolic syndrome was more common in sleep apneic subjects than in controls (58 versus 30 %). Female sleep apneics showed higher rate of metabolic syndrome than those of males (74 versus 52 %). Hypertension, diabetes mellitus, coronary artery disease, and left ventricular hypertrophy were detected higher in males with syndrome Z than in males without metabolic syndrome. Snoring and excessive daytime sleepiness were detected higher in females with syndrome Z than in females without metabolic syndrome. Systemic/pulmonary hypertension, diabetes mellitus, and left ventricular hypertrophy were more common in females with syndrome Z than in females without metabolic syndrome. Complaints of headache and systemic/pulmonary hypertension were more common among females than males with syndrome Z. Female syndrome Z patients had lower minimum oxygen saturation than male patients with syndrome Z. Metabolic syndrome in sleep apneic patients is more prevalent than in controls. All metabolic syndrome parameters were significantly different among obstructive sleep apneic patients with respect to gender with more severe

    OBJECTIVE Developing countries are undergoing an epidemiologic transition accompanied by increasing burden of cardiovascular disease (CVD) linked to urbanization and lifestyle modifications. Metabolic syndrome is a cluster of CVD risk factors whose extent in Kenya remains unknown. The aim of this study was to determine the prevalence of metabolic syndrome and factors associated with its occurrence among an urban population in Kenya. RESEARCH DESIGN AND METHODS This was a household cross-sectional survey comprising 539 adults (aged ≥18 years) living in Nairobi, drawn from 30 clusters across five socioeconomic classes. Measurements included waist circumference, HDL cholesterol, triacylglycerides (TAGs), fasting glucose, and blood pressure. RESULTS The prevalence of metabolic syndrome was 34.6% and was higher in women than in men (40.2 vs. 29%; P < 0.001). The most frequently observed features were raised blood pressure, a higher waist circumference, and low HDL cholesterol (men: 96.2, 80.8, and 80%; women: 89.8, 97.2, and 96.3%, respectively), whereas raised fasting glucose and TAGs were observed less frequently (men: 26.9 and 63.3%; women: 26.9 and 30.6%, respectively). The main factors associated with the presence of metabolic syndrome were increasing age, socioeconomic status, and education. CONCLUSIONS Metabolic syndrome is prevalent in this urban population, especially among women, but the incidence of individual factors suggests that poor glycemic control is not the major contributor. Longitudinal studies are required to establish true causes of metabolic syndrome in Kenya. The Kenyan government needs to create awareness, develop prevention strategies, and strengthen the health care system to accommodate screening and management of CVDs. PMID:22374643

    Developing countries are undergoing an epidemiologic transition accompanied by increasing burden of cardiovascular disease (CVD) linked to urbanization and lifestyle modifications. Metabolic syndrome is a cluster of CVD risk factors whose extent in Kenya remains unknown. The aim of this study was to determine the prevalence of metabolic syndrome and factors associated with its occurrence among an urban population in Kenya. This was a household cross-sectional survey comprising 539 adults (aged ≥18 years) living in Nairobi, drawn from 30 clusters across five socioeconomic classes. Measurements included waist circumference, HDL cholesterol, triacylglycerides (TAGs), fasting glucose, and blood pressure. The prevalence of metabolic syndrome was 34.6% and was higher in women than in men (40.2 vs. 29%; P < 0.001). The most frequently observed features were raised blood pressure, a higher waist circumference, and low HDL cholesterol (men: 96.2, 80.8, and 80%; women: 89.8, 97.2, and 96.3%, respectively), whereas raised fasting glucose and TAGs were observed less frequently (men: 26.9 and 63.3%; women: 26.9 and 30.6%, respectively). The main factors associated with the presence of metabolic syndrome were increasing age, socioeconomic status, and education. Metabolic syndrome is prevalent in this urban population, especially among women, but the incidence of individual factors suggests that poor glycemic control is not the major contributor. Longitudinal studies are required to establish true causes of metabolic syndrome in Kenya. The Kenyan government needs to create awareness, develop prevention strategies, and strengthen the health care system to accommodate screening and management of CVDs.

    Scientific data have amply demonstrated that work stress increases the risk of cardiovascular disease. However, less attention has been given to the association between stress and metabolic syndrome. In this study, our aim was to investigate the relationship between work stress and metabolic syndrome in a population of radiologists. Radiologists and radiotherapists taking part in scientific conferences were invited to compile a questionnaire to evaluate work stress and the main parameters for diagnosing metabolic syndrome (obesity, hypertension, elevated cholesterol level, elevated triglycerides, and hyperglycemia). Most of the doctors taking part in the survey (n = 383, 58.6 %) were found to have at least one pathological component; 47 subjects (7.1 %) had metabolic syndrome. All the variables indicating work stress, whether derived from Karasek's demand/control model or from the effort/reward model devised by Siegrist, were significant predictors of metabolic syndrome components. Radiologists with elevated levels of stress had a significantly higher risk of being affected by metabolic syndrome than colleagues with lower stress levels, whether stress was defined as "job strain", i.e., elevated work load and reduced discretionary power (OR 4.89, 95 % CI 2.51-9.55), or as "effort reward imbalance", i.e., mismatch between effort and reward for the work performed (OR 4.66, 95 % CI 2.17-10.02). Should the results of this cross-sectional study be confirmed by a subsequent longitudinal survey, they would indicate the need for prompt organizational intervention to reduce occupational stress in radiologists.

    The concept of the metabolic syndrome, although controversial, continues to gain acceptance. Whereas each risk factor of the metabolic syndrome (visceral obesity, atherogenetic dyslipidemia, elevated blood pressure, and dysglycemia) can be dealt with individually, the recommended initial therapeutic approach is to focus on reversing its root causes of atherogenetic diet, sedentary lifestyle, and overweight or obesity. No single diet is currently recommended for patients with the metabolic syndrome, although epidemiologic evidence suggests a lower prevalence of the metabolic syndrome associated with dietary patterns rich in fruit, vegetables, whole grains, dairy products, and unsaturated fats. We conducted a literature search to identify clinical trials specifically dealing with the resolution of the metabolic syndrome by lifestyle, drugs, or obesity surgery. Criteria used for study selection were English language, randomized trials with a placebo or control group (except for surgery), a follow-up lasting>or=6 mo, and a time frame of 5 y. We identified 3 studies based on lifestyle interventions, 5 studies based on drug therapy, and 3 studies based on laparoscopic weight-reduction surgery The striking resolution of the metabolic syndrome with weight-reduction surgery (93%) as compared with lifestyle (25%) and drugs (19%) strongly suggests that obesity is the driving force for the occurrence of this condition. Although there is no "all-inclusive" diet yet, it seems plausible that a Mediterranean-style diet has most of the desired attributes, including a lower content of refined carbohydrates, a high content of fiber, a moderate content of fat (mostly unsaturated), and a moderate-to-high content of vegetable proteins.

    The environmental risk factors such as food intake and physival activity, are determinants in the etiology of metabolic syndrome in overweight adolescents. To explore the association between environmental risk factors and components presence of metabolic syndrome in overweight youngsters in Medellín. Adolescents between the ages of 10 and 18 were selected for a cross sectional study. Body composition by anthropometry, blood pressure, lipid profile, glucose, insulin, food intake and physical activity level were assessed in the study population. The prevalence for metabolic syndrome components of hypertriglyceridemia was 40.9%; hypertension, 20.9%; low HDLc, 15.6%; high waist circumference, 4.0%, and hyperglycemia, 0.9%; the overall prevalence of metabolic syndrome was 3.1%. There was a statistical difference (p<0.005) between the consumption of calories, simple and total carbohydrates and the presence of the components; no association was found between the level of physical activity and the presence of components (p>0.05). The logistic regression model showed a higher probability of having at least one component if the youngster was male (p=0.022), with a higher BMI (Body Mass Index)(p=0.019) and was located in the fourth simple carbohydrates consumption quartile (p=0.036). Environmental risk factors associated with components of metabolic syndrome were the increased consumption of calories, simple and complex carbohydrates, all directly related to the BMI. In contrast, the level of physical activity, family history and personal risk factors showed no association. The metabolic syndrome only occurred in youngsters with obesity.

    To evaluate the frequency of metabolic syndrome in patients with Ischaemic Heart Disease. This was a cross sectional observational study. Patients with a first time cardiac event arriving in emergency room during the period October 2009 to April 2010, were included. Five components of Metabolic syndrome were defined according to criteria set by International Diabetes Federation, American Heart Association & National Heart, Lung and Blood Institute which had abdominal obesity (waist circumference) as an integral part of the syndrome. Blood sugar, triglycerides, HDL-C were measured within 24 hrs of cardiac insult. Hypertension was defined as blood pressure > 130/85 mmHg. Variables were integrated for descriptive statistics. A total of 477 patients diagnosed with Ischaemic Heart Disease were inducted in the study. There were 355 (74%) males and 122 (26%) females. Frequency of metabolic syndrome in Ischaemic heart disease was seen in 195 (54.95%) males and 96 (78.7%) females (p < 0.001). According to recent criteria abdominal obesity was observed in 91 (81.1%) females as compared to males 219 (61.7%) (p < 0.001) Similarly, low HDL and Hypertension were high in frequency in females. No significant difference in triglycerides levels was found in either gender. Frequency of metabolic syndrome with Ischaemic heart disease was high in females as compared to males. This could be attributed to the increased prevalence of abdominal obesity.

    Epigenetic mechanisms are emerging as mediators linking early environmental exposures during pregnancy with programmed changes in gene expression that alter offspring growth and development. There is irrefutable evidence from human and animal studies that nutrient and environmental agent exposures (for example, endocrine disruptors) during pregnancy may affect fetal/newborn development resulting in offspring obesity and obesity-associated metabolic abnormalities (metabolic syndrome). This concept of 'gestational programming' is associated with alterations to the epigenome (nongenomic) rather than changes in the DNA sequence (genomic). Epigenetic alterations induced by suboptimal maternal nutrition/endocrine factors include DNA methylation, histone modifications, chromatin remodeling and/or regulatory feedback by microRNAs, all of which have the ability to modulate gene expression and promote the metabolic syndrome phenotype. Recent studies have shown tissue-specific transcriptome patterns and phenotypes not only in the exposed individual, but also in subsequent progeny. Notably, the transmission of gestational programming effects to subsequent generations occurs in the absence of continued adverse environmental exposures, thus propagating the cycle of obesity and metabolic syndrome. This phenomenon may be attributed to an extrinsic process resulting from the maternal phenotype and the associated nutrient alterations occurring within each pregnancy. In addition, epigenetic inheritance may occur through somatic cells or through the germ line involving both maternal and paternal lineages. Since epigenetic gene modifications may be reversible, understanding how epigenetic mechanisms contribute to transgenerational transmission of obesity and metabolic dysfunction is crucial for the development of novel early detection and prevention strategies for programmed metabolic syndrome. In this review we discuss the evidence in human and animal studies for the role of

    Since the incidence of the metabolic syndrome is on the rise in the western world, its coherence to cancer is becoming more apparent. In this review we discuss the different potential factors involved in the increase of cancer in the metabolic syndrome including obesity, dyslipidemia and Type 2 Diabetes Mellitus (T2DM) as well as inflammation and hypoxia. We especially focus on the insulin and IGF systems with their intracellular signaling cascades mediated by different receptor subtypes, and suggest that they may play major roles in this process. Understanding the mechanisms involved will be helpful in developing potential therapeutics. PMID:21912508

    Wolfram syndrome (WS), also known as DIDMOAD (Diabetes Insipidus, Diabetes Mellitus, Optic Atrophy and Deafness), is a neurodegenerative disease with autosomal recessive inheritance with incomplete penetrance. DIDMOAD is a very rare disease with an estimated prevalence of 1 in 770,000 and it is believed to occur in 1 of 150 patients with juvenile-onset insulin-dependent diabetes mellitus. Additionally, WS may also present with different endocrine and metabolic abnormalities such as anterior and posterior pituitary gland dysfunction. This mini-review summarizes the variable presentation of WS and the need of screening for other metabolic and hormonal abnormalities, coexisting in this rare syndrome.

    Individuals with low socioeconomic position (SEP) and Latino ethnicity are at high risk for the metabolic syndrome. In part, this may reflect that these populations benefit from fewer resilient resources to manage stressful environments, resulting in accentuated psychological and physiological costs (1). We examined the direct effects of educational attainment (an indicator of SEP) and psychosocial resources on metabolic syndrome variables, and tested indirect effects of education, via resources. Participants were 145 middle-aged (M=47.07 years) Latinas recruited from health clinics along the California-Mexico border. Women completed assessments of demographics and resilient resources; metabolic syndrome variables were measured (blood pressure [BP], waist circumference [WC]) or abstracted from medical charts (lipids, glucose). Women with less education reported fewer psychosocial resources (DeltaR2=.14, p<.0001) and showed a higher risk profile on measures of BP, WC, and plasma glucose (3-7% of variance explained, all ps<.05), relative to those with more education. Resources independently predicted lower WCs (DeltaR2=.07, p<.05). Education exerted an indirect effect (p<.05) through resources on WC, a core factor underlying the metabolic syndrome. Additional research is warranted to further explore the roles of resilient resources in relationships among SEP, metabolic risk factors, and chronic disease processes.

    This review discusses the prevalence of metabolic syndrome and cardiovascular disease in the South Asian population, evaluates conventional and emerging risk factors, and reinforces the need for ethnic-specific redefinition of guidelines used to diagnose metabolic syndrome. We reviewed recent and past literature using Ovid Medline and PubMed databases. South Asians represent one of the largest and fastest growing ethnic groups in the world. With this growth, a dramatic rise in the rates of acute myocardial infarction and diabetes is being seen in this population. Potential etiologies for this phenomenon include dietary westernization, poor lifestyle measures, adverse body fat patterning, and genetics. While traditional risk factors for diabetes and cardiovascular disease should not be overlooked, early metabolic syndrome has now been shown in the South Asian pediatric population, suggesting that "metabolic programming" and perinatal influences may likely play a substantial role. Health care practitioners must be aware that current guidelines used to identify individuals with metabolic syndrome are underestimating South Asian individuals at risk. New ethnic-specific guidelines and prevention strategies are discussed in this review and should be applied by clinicians to their South Asian patients.

    Patients with schizophrenia exhibit a reduced life expectancy. Although unhealthy lifestyle or suicide risk plays a role, the main causes are diverse medical conditions such as cardiovascular diseases, type 2 diabetes mellitus and metabolic syndrome. Albeit pharmacological secondary side effects might also trigger previous conditions, studies in naïve patients reflect diverse anomalies at the onset. Patients with a first episode of psychosis, display a wide scope of metabolic abnormalities, ranging from normality till pathological values depending on the parameters studied. We attempted to evaluate the metabolic syndrome and glycemic homeostasis in a subset of antipsychotic-naïve patients with a first episode of non-affective psychosis. Patients (n=84) showed a similar prevalence of metabolic syndrome compared with a matched control sample (n=98) (6% vs 4%, P=0.562), while glucose homeostasis values differed significantly (14% vs. 5%, P=0.034). Our results suggest that metabolic syndrome is not a useful clinical condition to be evaluated in patients before pharmacological treatment. Abnormal glycemic homeostasis at the onset of the disease requires specific diagnostic tools and preventive measures in order to avoid future cardiovascular events. New strategies must be implemented in order to evaluate the cardiovascular risk and subsequent morbidity in patients at the onset of the disease.

Research in animal models has demonstrated that the gut microbiome has the functional capacity to induce or relieve metabolic syndrome. One way to modify the human gut microbiome is by transplanting fecal matter, which contains an abundance of live microorganisms, from a healthy individual to a diseased one in the hopes of alleviating illness. Here we review recent evidence suggesting efficacy of fecal microbiota transplant (FMT) in animal models and humans for the treatment of obesity and its associated metabolic disorders. PMID:27698622

    The cardiorenal metabolic syndrome (CRS) consists of a constellation of cardiac, renal, and metabolic disorders including insulin resistance (IR), obesity, metabolic dyslipidemia, high-blood pressure, and evidence of early cardiac and renal disease. Mitochondria dysfunction often occurs in the CRS, and this dysfunction is promoted by excess reactive oxygen species, genetic factors, IR, aging, and altered mitochondrial biogenesis. Recently, it has been shown that there are important sex-related differences in mitochondria function and metabolic, cardiovascular, and renal components. Sex differences in the CRS have mainly been attributed to the estrogen’s effects that are mainly mediated by estrogen receptor (ER) α, ERβ, and G-protein coupled receptor 30. In this review, we discuss the effects of estrogen on the mitochondrial function, insulin metabolic signaling, glucose transport, lipid metabolism, and inflammatory responses from liver, pancreatic β cells, adipocytes, skeletal muscle, and cardiovascular tissue.

    The metabolic syndrome is a cluster of risk factors (central obesity, hyperglycaemia, dyslipidaemia and arterial hypertension), indicating an increased risk of diabetes, cardiovascular disease and premature mortality. The gastrointestinal tract is seldom discussed as an organ system of principal importance for metabolic diseases. The present overview connects various metabolic research lines into an integrative physiological context in which the gastrointestinal tract is included. Strong evidence for the involvement of the gut in the metabolic syndrome derives from the powerful effects of weight-reducing (bariatric) gastrointestinal surgery. In fact, gastrointestinal surgery is now recommended as a standard treatment option for type 2 diabetes in obesity. Several gut-related mechanisms that potentially contribute to the metabolic syndrome will be presented. Obesity can be caused by hampered release of satiety-signalling gut hormones, reduced meal-associated energy expenditure and microbiota-assisted harvest of energy from nondigestible food ingredients. Adiposity per se is a well-established risk factor for hyperglycaemia. In addition, a leaky gut mucosa can trigger systemic inflammation mediating peripheral insulin resistance that together with a blunted incretin response aggravates the hyperglycaemic state. The intestinal microbiota is strongly associated with obesity and the related metabolic disease states, although the mechanisms involved remain unclear. Enterorenal signalling has been suggested to be involved in the pathophysiology of hypertension and postprandial triglyceride-rich chylomicrons; in addition, intestinal cholesterol metabolism probably contributes to atherosclerosis. It is likely that in the future, the metabolic syndrome will be treated according to novel pharmacological principles interfering with gastrointestinal functionality.

    Background Recent advances in genetics are particularly relevant in the field of intellectual disability (ID), where sub-microscopic deletions or duplications of genetic material are increasingly implicated as known or suspected causal factors. Data-driven reports on the impact of providing an aetiological explanation in ID are needed to help justify widespread use of new and expensive genetic technologies. Methods We conducted a survey of caregivers on the value of a genetic/aetiologic diagnosis of 22q11.2 deletion syndrome (22q11.2DS), the most common microdeletion syndrome in ID. We also surveyed the opinion of a high-functioning subset of adults with 22q11.2DS themselves. We used standard quantitative and qualitative methods to analyse the responses. Results In total, 73 of 118 surveys were returned (61.9%). There was convergence of quantitative and qualitative results, and consistency between adult patient and caregiver responses. A definitive molecular diagnosis of 22q11.2DS was a critical event with diverse positive repercussions, even if occurring later in life. Frequently cited benefits included greater understanding and certainty, newfound sense of purpose and a platform for advocacy, and increased opportunities to optimise medical, social and educational needs. Conclusions This is the first study to characterise the impact of a diagnosis of this representative microdeletion syndrome on adult patients and their families. The results both validate and expand on the theoretical benefits proposed by clinicians and researchers. The use of genome-wide microarray technologies will provide an increasing number of molecular diagnoses. The importance of a diagnosis of 22q11.2DS demonstrated here therefore has implications for changing attitudes about molecular genetic diagnosis that could benefit individuals with ID of currently unknown cause and their families.

    Long-term childhood cancer survivors are at great risk of developing late adverse effects after treatment, such as, reduced growth, obesity, decreased fertility, high blood pressure, cardiovascular diseases, impaired glucose, another form of cancer, among others organ dysfunctions, some of them are part of the metabolic syndrome. Metabolic syndrome and cancer connection is still not entirely understood, but there are some notions about it. Metabolic alterations produced during childhood cancer are more likely determined by treatments like radiotherapy, chemotherapy, glucocorticoids therapy, and surgery. Cancer treatment is associated to vascular alterations, hormone deficiencies, changes in insulin sensitivity, lipid metabolism, and inflammatory mediators. Obesity has been considered a crucial component in metabolic syndrome; obesity risk factors during childhood cancer include cranial radiation, female gender, and exposure to glucocorticoids such as dexamethasone. In addition, local radiotherapy or surgery may cause endocrine deficiencies, depends on the directly damage of endocrine organs. Patients who received some types of cancer treatment should be evaluated periodically to early diagnostic metabolic disorders associated to antineoplastic therapy.

    Increase in prevalence of obesity has become a worldwide major health problem in adults, as well as among children and adolescents. Furthermore, total adiposity and truncal subcutaneous fat accumulation during adolescence are positively and independently associated with atherosclerosis at adult ages. Centrally accumulation of body fat is associated with insulin resistance, whereas distribution of body fat in a peripheral pattern is metabolically less important. Obesity is associated with a large decrease in life expectancy. The effect of extreme obesity on mortality is greater among younger than older adults. In this respect, obesity is also associated with increased risk of several cancer types. However, up to 30% of obese patients are metabolically healthy with insulin sensitivity similar to healthy normal weight individuals, lower visceral fat content, and lower intima media thickness of the carotid artery than the majority of metabolically "unhealthy" obese patients.Abdominal obesity is the most frequently observed component of metabolic syndrome. The metabolic syndrome; clustering of abdominal obesity, dyslipidemia, hyperglycemia and hypertension, is a major public health challenge. The average prevalence of metabolic syndrome is 31%, and is associated with a two-fold increase in the risk of coronary heart disease, cerebrovascular disease, and a 1.5-fold increase in the risk of all-cause mortality.

    Trace metals play an important role in the proper functioning of carbohydrate and lipid metabolism. Some of the trace metals are thus essential for maintaining homeostasis, while deficiency of these trace metals can cause disorders with metabolic and physiological imbalances. This article concentrates on three trace metals (selenium, vanadium, and chromium) that may play crucial roles in controlling blood glucose concentrations possibly through their insulin-mimetic effects. For these trace metals, the level of evidence available for their health effects as supplements is weak. Thus, their potential is not fully exploited for the target of metabolic syndrome, a constellation that increases the risk for cardiovascular disease and type 2 diabetes. Given that the prevalence of metabolic syndrome is increasing throughout the world, a simpler option of interventions with food supplemented with well-studied trace metals could serve as an answer to this problem. The oxidation state and coordination chemistry play crucial roles in defining the responses to these trace metals, so further research is warranted to understand fully their metabolic and cardiovascular effects in human metabolic syndrome.

    Purpose Long-term survivors of childhood cancer appear to have an increased risk for the metabolic syndrome, subsequent type 2 diabetes and cardiovascular disease in adulthood compared to healthy children. The purpose of this study was to investigate the frequency of the metabolic syndrome and associated factors in childhood cancer survivors at a single center in Korea. Methods We performed a retrospective review of medical records of 98 childhood cancer survivors who were diagnosed and completed anticancer treatment at Samsung Medical Center, Seoul, Korea between Jan. 1996 and Dec. 2007. Parameters of metabolic syndrome were evaluated between Jan. 2008 and Dec. 2009. Clinical and biochemical findings including body fat percentage were analyzed. Results A total of 19 (19.4%) patients had the metabolic syndrome. The median body fat percentage was 31.5%. The body mass index and waist circumference were positively correlated with the cranial irradiation dose (r=0.38, P<0.001 and r=0.44, P<0.00, respectively). Sixty-one (62.2%) patients had at least one abnormal lipid value. The triglyceride showed significant positive correlation with the body fat percentage (r=0.26, P=0.03). The high density lipoprotein cholesterol showed significant negative correlation with the percent body fat (r=-0.26, P=0.03). Conclusion Childhood cancer survivors should have thorough metabolic evaluation including measurement of body fat percentage even if they are not obese. A better understanding of the determinants of the metabolic syndrome during adolescence might provide preventive interventions for improving health outcomes in adulthood. PMID:21949520

    Metabolic syndrome is a cluster of risk factors, such as obesity, insulin resistance, and hyperlipidemia that increases the individual’s likelihood of developing cardiovascular diseases. Patients inflicted with metabolic disorders also suffer from tissue repair defect. Mitsugumin 53 (MG53) is a protein essential to cellular membrane repair. It facilitates the nucleation of intracellular vesicles to sites of membrane disruption to create repair patches, contributing to the regenerative capacity of skeletal and cardiac muscle tissues upon injury. Since individuals suffering from metabolic syndrome possess tissue regeneration deficiency and MG53 plays a crucial role in restoring membrane integrity, we studied MG53 activity in mice models exhibiting metabolic disorders induced by a 6 month high-fat diet (HFD) feeding. Western blotting showed that MG53 expression is not altered within the skeletal and cardiac muscles of mice with metabolic syndrome. Rather, we found that MG53 levels in blood circulation were actually reduced. This data directly contradicts findings presented by Song et. al that indict MG53 as a causative factor for metabolic syndrome (Nature 494, 375-379). The diminished MG53 serum level observed may contribute to the inadequate tissue repair aptitude exhibited by diabetic patients. Furthermore, immunohistochemical analyses reveal that skeletal muscle fibers of mice with metabolic disorders experience localization of subcellular MG53 around mitochondria. This clustering may represent an adaptive response to oxidative stress resulting from HFD feeding and may implicate MG53 as a guardian to protect damaged mitochondria. Therapeutic approaches that elevate MG53 expression in serum circulation may be a novel method to treat the degenerative tissue repair function of diabetic patients. PMID:25950605

    Perkins, Jennifer M; Davis, Stephen N

    2008-02-01

    The endocannabinoid system (ECS) plays a physiologic role in modulating energy balance, feeding behavior, lipoprotein metabolism, insulin sensitivity, and glucose homeostasis, which when dysregulated can all contribute to cardiometabolic risk. Evidence has suggested that the ECS is overactive in human obesity and in animal models of genetic and diet-induced obesity. ECS stimulation centrally and peripherally drives metabolic processes that mimic the metabolic syndrome. These findings have led to the development of potential novel therapeutic targets, including the drug rimonabant, a selective CB1 receptor antagonist, which has been shown to promote weight loss, reduce inflammation, improve dyslipidemia, and improve glucose homeostasis.

    Asthma and obesity are epidemiologically linked; however, similar relationships are also observed with other markers of the metabolic syndrome, such as insulin resistance and dyslipidemia, which cannot be accounted for by increased body mass alone. Obesity appears to be a predisposing factor for the asthma onset, both in adults and in children. In addition, obesity could make asthma more difficult to control and to treat. Although obesity may predispose to increased Th2 inflammation or tendency to atopy, other mechanisms need to be considered, such as those mediated by hyperglycaemia, hyperinsulinemia and dyslipidemia in the context of metabolic syndrome. The mechanisms underlying the association between asthma and metabolic syndrome are yet to be determined. In the past, these two conditions were believed to occur in the same individual without any pathogenetic link. However, the improvement in asthma symptoms following weight reduction indicates a causal relationship. The interplay between these two diseases is probably due to a bidirectional interaction. The purpose of this review is to describe the current knowledge about the possible link between metabolic syndrome and asthma, and explore potential application for future studies and strategic approaches.

    The worldwide epidemic of diabetes and metabolic syndrome in the last few decades cannot be fully accounted for only by changes in the lifestyle factors, such as sedentary lifestyle and overeating. Besides genetic factors, there must be other causes to explain this rapid change. They could not be infectious in nature and induce insulin resistance as key biochemical abnormality. Mitochondrial dysfunction could be underlying mechanism behind the insulin resistance, thus metabolic syndrome. Then there have been increasing number of reports suggesting that chronic exposure to and accumulation of endocrine disrupting chemicals (EDCs), especially so-called the persistent organic pollutants (POPs) within the body might be associated with metabolic syndrome. Combining two concepts, we developed new "EDCs-induced mitochondrial dysfunction hypothesis of metabolic syndrome". In this review we suggest that classifying those chemicals into 5 groups might be clinically useful considering their removal or avoidance; POPs, non-persistent organic pollutants, heavy metals, air pollutants and drugs. We will also discuss briefly how those insights could be applied to clinical medicine.

  3. Metabolic syndrome and breast cancer: is there a link?

    PubMed

    Hauner, Dagmar; Hauner, Hans

    2014-04-01

    Epidemiological data suggest a close link between obesity and breast cancer, the most frequently occurring cancer in women. The metabolic syndrome is typically associated with abdominal obesity and comprises disturbances in glucose and/or lipid metabolism and/or hypertension. Recent studies have established a specific association between the metabolic syndrome - as well as its components - and breast cancer, indicating both an increased risk of developing breast cancer and a poorer prognosis. In premenopausal women, obesity might have a protective effect only on receptor-positive tumors, whereas a positive association was observed between obesity/abdominal obesity and an increased risk of triple-negative breast cancer (TNBC). Overall survival and disease-free survival were reported to be significantly shorter in premenopausal obese women with TNBC compared to non-obese women, but these results are still inconsistent and need further research. The metabolic syndrome is characterized by a state of insulin resistance/hyperinsulinemia and subacute chronic inflammation, with both conditions offering a plausible mechanistic link towards breast cancer. Thus, in addition to their increased risk of cardiovascular morbidity and mortality, women with this syndrome represent a group at elevated risk of developing breast cancer and with poorer prognosis.

    Nonalcoholic steatohepatitis (NASH) and the metabolic syndrome (MetS) are highly prevalent in the Western population. Their pathogenesis is closely linked to insulin resistance, which serves as a therapeutic target for the management of these conditions. This review article reviews the research supporting the influence of MetS on NASH and includes studies supporting their similar epidemiology, pathogenesis, and treatment.

  6. The role of testosterone in the metabolic syndrome: a review.

    PubMed

    2009-03-01

    Over the last three decades it has become apparent that testosterone plays a significant role in the maintenance of bone and muscle mass, in erythropoiesis, and in mental functions. But testosterone is also a key player in glucose homeostasis and lipid metabolism. The metabolic syndrome is a clustering of risk factors predisposing to late onset diabetes mellitus, atherosclerosis and cardiovascular morbidity and mortality. The main components of the syndrome are visceral obesity, glucose intolerance, raised blood pressure and dyslipidaemia (elevated triglycerides, low levels of high-density lipoprotein cholesterol),and a pro-inflammatory and thrombogenic state. Cross-sectional epidemiological studies have reported a direct correlation between plasma testosterone and insulin sensitivity, and low testosterone levels are associated with an increased risk of type 2 diabetes mellitus, dramatically illustrated by androgen deprivation in men with prostate carcinoma. Lower total testosterone and sex hormone-binding globulin(SHBG) predict a higher incidence of the metabolic syndrome. There is now evidence to argue that hypotestosteronaemia should be an element in the definition of the metabolic syndrome. Administration of testosterone to hypogonadal men reverses the unfavorable risk profile for the development of diabetes and atherosclerosis. Testosterone should be regarded as a pivotal hormone for men's health.

    [Purpose] This study investigated the serologic factors associated with metabolic syndrome and gallstones. [Subjects and Methods] The study evaluated subjects who visited a health promotion center in Seoul from March 2, 2013 to February 28, 2014, and had undergone abdominal ultrasonography. Height, weight, and blood pressure were measured. Blood sampling was performed for high-density lipoprotein cholesterol, triglyceride, fasting blood glucose, total bilirubin, direct bilirubin, indirect bilirubin, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, uric acid, total cholesterol, low-density lipoprotein cholesterol, thyroid stimulating hormone, and red and white blood cell counts. We conducted logistic regression analysis to assess the risk factors associated with metabolic syndrome. [Results] The risk factors for metabolic syndrome in men, in order of decreasing weight, were red blood cell count, body mass index, maximum size of gallstones, white blood cell count, waist circumference, and uric acid level. The factors in women, in order of decreasing weight, were red blood cell count, presence/absence of gallstones, uric acid level, body mass index, fasting blood glucose, and waist circumference. [Conclusion] Most serum biochemical factors and gallstone occurrence could be used to indicate the presence or absence of metabolic syndrome, independent of gender. PMID:27630427

  11. Is insulin resistance the cause of the metabolic syndrome?

    PubMed

    Ferrannini, Ele

    2006-01-01

    Following up on original descriptions of clustering of cardiovascular risk factors (chiefly, glucose intolerance, dyslipidaemia and hypertension) around the presence of insulin resistance, the metabolic syndrome has recently been upgraded to the status of a disease entity with an inherent predictive value for cardiovascular disease. In pathophysiological terms, insulin resistance (of glucose metabolism) and the attendant compensatory hyperinsulinaemia are causally related to each of glucose intolerance, dyslipidaemia, high blood pressure and vascular dysfunction. The physiological mechanisms are concisely reviewed here. However, insulin resistance/hyperinsulinaemia alone is insufficient to cause these abnormalities, for which other pathogenic factors (e.g. ss-cell dysfunction for glucose intolerance) are required. The metabolic syndrome, on the other hand, has evolved from a set of statistical associations believed to carry an excess of cardiovascular risk. In the various existing definitions, a mixture of physical, metabolic and clinical variables have been used on grounds of predictive value or practical ease. These variables belong to different phenotypes, which are upstream, intermediate and proximal, respectively, in their relation to clinical disease. The resulting 'syndromes' usually lack a cogent conceptual structure, may reflect the particular data set from which they are extracted and may be of limited applicability. While overt diabetes, clinical hypertension and frank dyslipidaemia are often present together in the same patient, a subclinical syndrome with a distinct, probable aetiology and a proven power as a risk indicator remains to be identified.

    The coexistence of diabetes, hypertension, obesity, and dyslipidemia is defined as metabolic syndrome. Studies show substantial cardiovascular risks among these patients. The risk of patients with metabolic syndrome undergoing total joint arthroplasty (TJA) is unknown. Patients with and without metabolic syndrome undergoing TJA during a 3-year period were analyzed for postoperative complications. Metabolic syndrome was defined by having 3 of the following 4 criteria: obesity (body mass index ≥30 kg/m(2)), dyslipidemia, hypertension, and diabetes. Patients with metabolic syndrome had a significantly higher risk of cardiovascular complications compared with controls (P = .017). The risk of an adverse event increased by 29% and 32%, respectively, when there were 3 or 4 syndrome components. Patients with metabolic syndrome undergoing TJA have increased risk for cardiovascular complications. Our results show that metabolic syndrome may have a clustering effect and pose increased risk when individual risks factors are combined. Copyright © 2012 Elsevier Inc. All rights reserved.

    Background - Overweight and obesity are associated with metabolic syndrome and abdominal obesity, thereby increasing the risk of type 2 diabetes mellitus and cardiovascular diseases. In Brazil, there are still no precise data on the prevalence of these disorders, especially among individuals who carry out some kind of physical activity in public spaces and there are no education and prevention programs for obesity. Aim: To investigate the prevalence of metabolic syndrome and obesity among park users. Methods: A prospective, cross-sectional, descriptive study was conducted with 619 individuals assessed and stratified by profile according to a specific protocol. The group was characterized as follows: female (50.1%) and mean age =50.6±14.8, with predominance of individuals aged between 50 and 59 years (26.8%) and with higher education (68%) and a household income of between 4 and 10 minimum wages (29.2%). Results: Regular physical exercise was reported by 78% of the individuals and it was found that 70.7% were nevertheless of above normal weight: 45% overweight and 25.7% obese, of whom 20.7% had obesity grade I, 3.9% grade II and 1.1% grade III. The prevalence of metabolic syndrome was 4.3%, mostly in men (6.3%). Arterial hypertension and type 2 diabetes mellitus were detected in 17.8% and 5.5%, respectively. In view of the influence of obesity on the occurrence of type 2 diabetes mellitus and metabolic syndrome, it was found that this association was not significant for the two conditions (p=0.014 and 0.017, respectively). Conclusion : The findings demonstrate a high prevalence of overweight and obesity in the studied population, and metabolic syndrome in 4.3%, despite the fact that 70% reported engaging in regular physical activity.

    The aim of the present study was to determine the prevalence of metabolic syndrome and its individual components among the Iranian adult population in 2011 and to investigate changes between 2007 and 2011. Data from two rounds of the Surveillance of Risk Factors of Non-communicable Diseases national surveys conducted in 2007 and 2011 were pooled. Metabolic syndrome was defined according to International Diabetes Federation criteria. In 2007, the prevalence of metabolic syndrome among adults aged 25-64 years was 35.95 (95% confidence interval [CI] 34.27-37.63), which decreased to 32.96 (95% CI 30.73-35.18) in 2011 (P = 0.0108). Despite this overall decline, the prevalence of central obesity (P = 0.1383), raised triglycerides (P = 0.3058), and reduced high-density lipoprotein cholesterol (HDL-C; P = 0.5595) remained constant. There was a trend towards a decline in the proportion of individuals with increased blood pressure (P = 0.0978), and the proportion of adults with increased fasting plasma glucose (FPG) increased (P < 0.0001). In 2011, the prevalence of central obesity, raised triglycerides, reduced HDL-C, increased blood pressure and increased FPG was 51.88 (95% CI 48.97-54.79), 36.99 (95% CI 34.52-39.45), 54.72 (95% CI 50.87-58.57), 38.92 (95% CI 36.19-41.64), and 24.97 (95% CI 22.02-27.93) respectively. Over the period 2007-11, the prevalence of metabolic syndrome has decreased slightly in Iran, although prevalence of increased FPG has increased significantly. One-third of the Iranian adult population is diagnosed with metabolic syndrome. © 2016 Ruijin Hospital, Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

    Robust evidence of the association of insulin resistance and metabolic syndrome with acne in male patients is lacking. To assess the prevalence of metabolic syndrome and insulin resistance in male patients 20 years or older with acne. We performed a cross-sectional study in 100 male patients with acne and 100 age-matched male controls without acne from a dermatology outpatient department of a tertiary care institute. Postadolescent patients were recruited only to negate the effects of physiologic insulin resistance that are seen at the time of puberty and adolescence. Twenty-five patients were included in each of the 4 individual severity groups according to the Global Acne Grading System and were age matched to 100 male controls without acne. Clinical examination, Global Acne Rating System, National Cholesterol Education Programme Adult Treatment Panel III (NCEP-ATP III), and Homeostasis Model Assessment-Insulin Resistance (HOMA-IR). Metabolic syndrome was diagnosed as per the criteria of the modified NCEP-ATP III. Insulin resistance was assessed by the HOMA-IR. A HOMA-IR value greater than 2.5 was arbitrarily considered as insulin resistance. Prevalence of insulin resistance was significantly higher in cases (22%) compared with controls (11%) (P = .03). The prevalence of metabolic syndrome was comparable between cases (17%) and controls (9%) (P = .09). Prevalence of insulin resistance and metabolic syndrome did not differ significantly among the acne severity groups. Postadolescent male patients with acne more commonly have insulin resistance. This resistance may be a stage of prediabetes, and the patients may develop hyperinsulinemia or type 2 diabetes in the future. These patients should be followed up for a prolonged time to determine whether they develop conditions associated with insulin resistance.

    The prevalence of metabolic syndrome has reached epidemic levels in the Samoan Islands. In this cross-sectional study conducted in 2002-2003, dietary patterns were described among American Samoan (n = 723) and Samoan (n = 785) adults (> or =18 y) to identify neo-traditional and modern eating patterns and to relate these patterns to the presence of metabolic syndrome using Adult Treatment Panel III criteria. The neo-traditional dietary pattern, similar across both polities, was characterized by high intake of local foods, including crab/lobster, coconut products, and taro, and low intake of processed foods, including potato chips and soda. The modern pattern, also similar across both polities, was characterized by high intake of processed foods such as rice, potato chips, cake, and pancakes and low intake of local foods. The neo-traditional dietary pattern was associated with significantly higher serum HDL-cholesterol in American Samoa (P-trend = 0.05) and a decrease in abdominal circumference in American Samoa and Samoa (P-trend = 0.004 and 0.01, respectively). An inverse association was found with metabolic syndrome, although it did not reach significance (P = 0.23 in American Samoa; P = 0.13 in Samoa). The modern pattern was significantly positively associated with metabolic syndrome in Samoa (prevalence ratio = 1.21 for the fifth compared with first quintile; 95% CI: 0.93.1.57; P-trend = 0.05) and with increased serum triglyceride levels in both polities (P < 0.05). Reduced intake of processed foods high in refined grains and adherence to a neo-traditional eating pattern characterized by plant-based fiber, seafood, and coconut products may help to prevent growth in the prevalence of metabolic syndrome in the Samoan islands.

    A rare mutation in LRP6 has been shown to underlie autosomal dominant coronary artery disease (CAD) and metabolic syndrome in an Iranian kindred. The prevalence and spectrum of LRP6 mutations in the disease population of the United States is not known. Two hundred white Americans with early onset familial CAD and metabolic syndrome and 2,000 healthy Northern European controls were screened for nonconservative mutations in LRP6. Three novel mutations were identified, which cosegregated with the metabolic traits in the kindreds of the affected subjects and none in the controls. All three mutations reside in the second propeller domain, which plays a critical role in ligand binding. Two of the mutations substituted highly conserved arginines in the second YWTD domain and the third substituted a conserved glycosylation site. The functional characterization of one of the variants showed that it impairs Wnt signaling and acts as a loss of function mutation.

    The aim of this study was to determine the impact of a targeted, personalized wellness program on reducing employees' future risk of metabolic syndrome. Aetna piloted a year-long program that included a limited genetic profile, a traditional psychosocial assessment, and high-intensity coaching in a randomized controlled study of Aetna employees with an increased risk for metabolic syndrome. Sustained employee engagement of 50% over the course of 1 year; 76% of participating employees lost an average of 10 pounds (4.5 kg) (P < 0.001 vs baseline weight), and there were trends in improved clinical outcomes relative to three of five metabolic factors. Average health care costs were reduced by $122 per participant per month, resulting in a positive return on investment in the program's first year. At scale, such programs would be expected to lead to significant downstream reduction in major clinical events and costs.

    2014-01-01

    Hyperuricemia has long been established as the major etiologic factor in gout. In recent years, a large body of evidence has accumulated that suggests that hyperuricemia may play a role in the development and pathogenesis of a number of metabolic, hemodynamic, and systemic pathologic diseases, including metabolic syndrome, hypertension, stroke, and atherosclerosis. A number of epidemiologic studies have linked hyperuricemia with each of these disorders. In some studies, therapies that lower uric acid may prevent or improve certain components of the metabolic syndrome. There is an association between uric acid and the development of systemic lupus erythematosus; the connection between other rheumatic diseases such as rheumatoid arthritis and osteoarthritis is less clear. The mechanism for the role of uric acid in disorders other than gout is not well established but recent investigations point towards systemic inflammation induced by urate, as the major pathophysiological event common to systemic diseases, including atherosclerosis.

    Despite growing interest, the behavioural ecology of deep-sea organisms is largely unknown. Much of this scarcity in knowledge can be attributed to deepwater animals being secretive or comparatively 'rare', as well as technical difficulties associated with accessing such remote habitats. Here we tested whether two species of giant marine isopod (Bathynomus giganteus, Booralana tricarinata) captured from 653 to 875 m in the Caribbean Sea near Eleuthera, The Bahamas, exhibited an activity behavioural syndrome across two environmental contexts (presence/absence of food stimulus) and further whether this syndrome carried over consistently between sexes. We also measured routine metabolic rate and oxygen consumption in response to a food stimulus in B. giganteus to assess whether these variables are related to individual differences in personality. We found that both species show an activity syndrome across environmental contexts, but the underlying mechanistic basis of this syndrome, particularly in B. giganteus, is unclear. Contrary to our initial predictions, neither B. giganteus nor B. tricarinata showed any differences between mean expression of behavioural traits between sexes. Both sexes of B. tricarinata showed strong evidence of an activity syndrome underlying movement and foraging ecology, whereas only male B. giganteus showed evidence of an activity syndrome. Generally, individuals that were more active and bolder, in a standard open arena test were also more active when a food stimulus was present. Interestingly, individual differences in metabolism were not related to individual differences in behaviour based on present data. Our study provides the first measurements of behavioural syndromes and metabolism in giant deep-sea isopods.

    Metabolic syndrome constitutes a group of disorders such as insulin resistance, hypertension, and hypertriglyceridemia, predisposing an individual to risk factors such as cardiovascular disease, diabetes, obesity, and dyslipidemia. A majority of these diseases are influenced by the environmental factors, nutrient uptake, and genetic profile of an individual that together dysregulate gene function. These genetic and nongenetic factors are reported to introduce epigenetic cues that modulate the gene function which is inherited by the offspring. Considering the epigenetic modulation of the metabolic disorders, nutrigenomics has been distinctly categorized as a branch that deals with modulatory effect of nutrients on metabolic disorders and disease progression by supplementing the individuals with key nutrient-enriched diets which are derived from plant and animal sources. Nutritional components of the diet regulate the metabolic health of an individual either by controlling the expression of some key genes related to metabolic pathways or by modulating the epigenetic events on such genes. The present article discusses various metabolic disorders in detail and the effect of nutrients on the specific genes causing those disorders. We also highlight the molecular mechanisms of some metabolic disorders through epigenetic modifications and possible therapeutic interventions. With the advent of high-throughput technologies and epigenetic modulation of the metabolic disorders, an altered epigenetic code that is programmed due to improper nutrients can be reverted back by supplementing the diet with various plant-derived compounds. The implication of small molecular drugs is also of utmost significance for challenging the metabolic disorders.

    Metabolic syndrome is associated with increased cardiac morbidity. The aim of this study was to evaluate exercise-induced hypertension (EIH) in men with metabolic syndrome and to explore potential associations with anthropometric and metabolic variables. A total of 179 normotensive men with metabolic syndrome underwent a maximal symptom-limited treadmill test. Blood pressure was measured at 5-min rest prior to exercise testing (anticipatory blood pressure), at every 3 min during the exercise, and during the recovery period. EIH was defined as maximum systolic blood pressure (SBP) ≥220 mmHg and/or maximum diastolic blood pressure (DBP) ≥100 mmHg. Of the 179 men, 87 (47%) presented EIH. Resting blood pressure values at baseline were 127±10/83±6 mmHg in EIH and 119±9/80±6 mmHg (P=0.01 for both) in normal blood pressure responders to exercise. Anticipatory SBP and DPS were higher in the group with EIH (P=0.001). Subjects with EIH presented higher waist circumference (WC) (P<0.01), low-density lipoprotein cholesterol (LDL-C), and apolipoprotein B (ApoB) levels as well as insulin resistance (all P<0.05). Abdominal subcutaneous adipose tissue and total body fat mass were comparable between groups. Subjects with EIH had higher abdominal visceral adipose tissue (P<0.001). The best predictors of EIH were resting SBP and abdominal obesity. Each increment of 5 cm in WC was associated with an odds ratio of 1.30 (1.20-1.68) for EIH. About half of our subjects with metabolic syndrome showed EIH. These men are characterized by a worsened metabolic profile. Our data suggest that a treadmill exercise test may be helpful to identify a potentially higher risk metabolic syndrome subset of subjects.

    The metabolic syndrome has become pandemic nature and tends to rejuvenation in the world. Elucidation of the pathogenic mechanisms on membrane-cell level will optimize the treatment of patients with metabolic syndrome and prevention of metabolic syndrome on the level of pre-clinical manifestations. to study the immunological status and lipid metabolism in the patients with metabolic syndrome and the pathogenetic mechanisms of metabolic syndrome were established. There were 4 groups of pacients (110) with: metabolic syndrome, ischemic heart disease and hypertension, hypertention; control group. General clinical, instrumental, laboratory and statistical methods were used. The levels of immune factors - interleukin-6 in supernatants of mononuclear cells by 65%, sICAM-1 by 20% is elevated in patients with metabolic syndrome compared with the control group. The increasing of the content of saturated fatty acids by 9.4% and polyunsaturated fatty acid by 36.6% lead to fundamental breach of structural and functional properties of membranes. There is significant common carotid artery intima media thickness on average twice at the patients with metabolic syndrome and with ischemic heart disease and hypertension. The immunoinflammatory reactions were more revealed in the group of patients with metabolic syndrome than in other groups. The lipid state at patients with metabolic syndrome was changed more than in patients with hypertension or patients with ischemic heart disease and hypertension both. Moreover our data indicate the presence of structural changes in the vessel wall in patients with metabolic syndrome.

    The selection of living kidney donors is based on a formal evaluation of the state of health. However, this spectrum of health includes subtle metabolic derangements that can cluster as metabolic syndrome. We studied the association of metabolic syndrome with kidney function and histology in 410 donors from 2005 to 2012, of whom 178 donors were systematically followed after donation since 2009. Metabolic syndrome was defined as per the NCEP ATPIII criteria, but using a BMI > 25 kg/m2 instead of waist circumference. Following donation, donors received counseling on lifestyle modification. Metabolic syndrome was present in 50 (12.2%) donors. Donors with metabolic syndrome were more likely to have chronic histological changes on implant biopsies than donors with no metabolic syndrome (29.0% vs. 9.3%, p < 0.001). This finding was associated with impaired kidney function recovery following donation. At last follow-up, reversal of metabolic syndrome was observed in 57.1% of donors with predonation metabolic syndrome, while only 10.8% of donors developed de novo metabolic syndrome (p < 0.001). In conclusion, metabolic syndrome in donors is associated with chronic histological changes, and nephrectomy in these donors was associated with subsequent protracted recovery of kidney function. Importantly, weight loss led to improvement of most abnormalities that define metabolic syndrome. PMID:23865821

    To examine the effect of melatonin given to rats simultaneously with fructose on initial and fully developed metabolic syndrome, male Wistar rats had free access to chow and 5% or 10% fructose drinking solution for 8 weeks. As compared to controls, systolic blood pressure augmented significantly under both treatments whereas excessive body weight was seen in rats receiving the 10% fructose only. Rats drinking 5% fructose showed a greater tolerance to a glucose load while rats having access to a 10% fructose drinking solution exhibited the expected impaired glucose tolerance found in the metabolic syndrome. Circulating triglyceride and low density lipoproteins-cholesterol (LDL-c) concentration augmented significantly in rats showing a fully developed metabolic syndrome only, while high blood cholesterol levels were found at both stages examined. Melatonin (25 μg/mL drinking solution) counteracted the changes in body weight and systolic blood pressure found in rats administered with fructose. Melatonin decreased the abnormal hyperglycemia seen after a glucose load in 10% fructose-treated rats but it did not modify the greater tolerance to glucose observed in animals drinking 5% fructose. Melatonin also counteracted the changes in plasma LDL-c, triglyceride and cholesterol levels and decreased plasma uric acid levels. The results underline a possible therapeutical role of melatonin in the metabolic syndrome, both at initial and established phases.

    Biological aging is typically associated with a progressive increase in body fat mass and a loss of lean body mass. Owing to the metabolic consequences of reduced muscle mass, it is understood that normal aging and/or decreased physical activity may lead to a higher prevalence of metabolic disorders. Lifestyle modification, specifically changes in diet, physical activity, and exercise, is considered the cornerstone of obesity management. However, for most overweight people it is difficult to lose weight permanently through diet or exercise. Thus, prevention of weight gain is thought to be more effective than weight loss in reducing obesity rates. A key question is whether physical activity can extenuate age-related weight gain and promote metabolic health in adults. Current guidelines suggest that adults should accumulate about 60 minutes of moderate-intensity physical activity daily to prevent unhealthy weight gain. Because evidence suggests that resistance training may promote a negative energy balance and may change body fat distribution, it is possible that an increase in muscle mass after resistance training may be a key mediator leading to better metabolic control.

    The aim of this study was to determine the association of sleep quality and sleep quantity with metabolic syndrome in Qazvin, Iran. this cross sectional study was conducted in 1079 residents of Qazvin selected by multistage cluster random sampling method in 2011. Metabolic syndrome was defined according to the criteria proposed by the national cholesterol education program third Adult treatment panel. Sleep was assessed using the Pittsburgh sleep quality index (PSQI). A logistic regression analysis was used to examine the association of sleep status and metabolic syndrome. Mean age was 40.08±10.33years. Of 1079, 578 (52.2%) were female, and 30.6% had metabolic syndrome. The total global PSQI score in the subjects with metabolic syndrome was significantly higher than subjects without metabolic syndrome (6.30±3.20 vs. 5.83±2.76, P=0.013). In logistic regression analysis, sleep disturbances was associated with 1.388 fold increased risk of metabolic syndrome after adjustment for age, gender, and body mass index. Sleep disturbances component was a predictor of metabolic syndrome in the present study. More longitudinal studies are necessary to understand the association of sleep quality and its components with metabolic syndrome. Copyright © 2017 Diabetes India. Published by Elsevier Ltd.

    Noncommunicable diseases are common among chronically infected patients with HIV in the developed world, but little is known about these conditions in African cohorts. We assessed the epidemiology of metabolic syndrome among young South African women during the first 3 years after HIV acquisition. A total of 160 women were followed prospectively in the CAPRISA 002 Acute Infection study. Metabolic syndrome was defined as a constellation of hyperlipidemia, hypertension, hyperglycemia/diabetes, and abdominal obesity. Time trends were assessed using generalized estimation equation models. Median age was 24 years and body mass index 27 kg/m. Prevalence of metabolic syndrome at infection was 8.7% increasing to 19.2% over 36 months (P = 0.001). The proportion of women with body mass index >30 kg/m increased from 34.4% to 47.7% (P = 0.004), those with abnormal waist circumference and elevated blood pressure increased from 33.5% to 44.3% (P = 0.060) and 23.8% to 43.9% (P < 0.001), respectively. Incidence of metabolic syndrome was 9.13/100 person-years (95% CI: 6.02 to 13.28). Predictors of metabolic syndrome were age (per year increase odds ratio (OR) = 1.12; 95% CI: 1.07 to 1.16), time postinfection (per year OR = 1.47; 95% CI: 1.12 to 1.92), family history of diabetes (OR = 3.13; 95% CI: 1.71 to 5.72), and the human leukocyte antigen (HLA)-B*81:01 allele (OR = 2.95; 95% CI: 1.21 to 7.17), whereas any HLA-B*57 or B*58:01 alleles were protective (OR = 0.34; 95% CI: 0.15 to 0.77). HIV-1 RNA (OR = 0.89; 95% CI: 0.62 to 1.27) and CD4 count (OR = 1.03; 95% CI: 0.95 to 1.11) did not predict metabolic syndrome. The high burden of metabolic conditions in young South African HIV-infected women highlights the need to integrate noncommunicable disease and HIV care programs. Interventions to prevent cardiovascular disease must start at HIV diagnosis, rather than later during the disease course.

    Seven alcoholic male subjects diagnosed as having Korsakoff's syndrome and eight age-matched male normal volunteers were studied with /sup 18/F 2-fluoro-2-deoxy-D-glucose (2/sup 18/FDG). All subjects were examined at rest with eyes covered in a quiet, darkened room. Serial plasma samples were obtained following injection of 4 to 5 mCi of 2/sup 18/FDG. Tomographic slices spaced at 10mm axial increments were obtained (in-plane resolution = 1.75 cm, axial resolution = 1.78 cm). Four planes were selected from each subject, and a total of 46 regions of interest were sampled and glucose metabolic rates for each region calculated. The mean glucose metalbolic rate for the 46 regions in the Korsakoff subjects was significantly lower than that in the normal controls (5.17 +- .43 versus 6.6 +- 1.31). A Q-component analysis, which examined each subject's regional rates relative to his mean rate, revealed two distinct patterns in the Korsakoff group. Glucose metabolism was significantly reduced in 37 of the 46 regions sampled. Reduced cerebral glucose metabolism in a nondemented group of subjects has not previously been reported. The reduction in cortical metabolism may be the result of damage to sub-cortical projecting systems. The differing patterns of cerebral metabolism in Korsakoff's syndrome suggests subgroups with differing neuropathology. Regions implicated in memory function, medial temporal, thalamic and medial prefrontal were among the regions reduced in metabolism.

    Metabolic syndrome (MetS) is a cluster of associated metabolic traits that collectively confer unsurpassed risk for development of cardiovascular disease (CVD) and type 2 diabetes compared to any single CVD risk factor. Truncal obesity plays an exceptionally critical role among all metabolic traits of the MetS. Consequently, the prevalence of the MetS has steadily increased with the growing epidemics of obesity. Pharmacotherapy has been available for obesity for more than one decade, but with little success in improving the metabolic profiles. The serotonergic drugs and inhibitors of pancreatic lipases were among the few drugs that were initially approved to treat obesity. At the present time, only the pancreatic lipase inhibitor orlistat is approved for long-term treatment of obesity. New classes of anti-diabetic drugs, including glucagon-like peptide 1 receptor (GLP-1R) agonists and Dipeptidyl-peptidase IV (DPP-IV) inhibitors, are currently being evaluated for their effects on obesity and metabolic traits. The genetic studies of obesity and metabolic syndrome have identified novel molecules acting on the hunger and satiety peptidergic signaling of the gut-hypothalamus axis or the melanocortin system of the brain and are promising targets for future drug development. The goal is to develop drugs that not only treat obesity, but also favorably impact its associated traits. PMID:26001373

    Metabolic syndrome refers to a clustering of established and emerging cardiovascular disease risk factors within a single individual. The established risk factors, such as obesity, diabetes, dyslipidaemia and hypertension, and other emerging risk factors are closely related to central obesity (especially intra-abdominal adiposity) and insulin resistance. However, debate continues about the very existence of the metabolic syndrome. Despite the controversies, many existing and new therapies are targeting the metabolic syndrome and component risk factors. To date, no therapies have been approved specifically for treating the metabolic syndrome. In this article some of the challenges and opportunities in developing therapies for the metabolic syndrome are discussed. PMID:23148153

    Background Parity increases the risk for coronary heart disease; however, its association with metabolic syndrome among women in low-income countries is still unknown. Objective This study investigates the association between parity or gravidity and metabolic syndrome in rural Bangladeshi women. Methods A cross-sectional study was conducted in 1,219 women aged 15–75 years from rural Bangladesh. Metabolic syndrome was defined according to the standard NCEP-ATP III criteria. Logistic regression was used to estimate the association between parity and gravidity and metabolic syndrome, with adjustment of potential confounding variables. Results Subjects with the highest gravidity (> = 4) had 1.66 times higher odds of having metabolic syndrome compared to those in the lowest gravidity (0-1) (Ptrend = 0.02). A similar association was found between parity and metabolic syndrome (Ptrend = 0.04), i.e., subjects in the highest parity (> = 4) had 1.65 times higher odds of having metabolic syndrome compared to those in the lowest parity (0-1). This positive association of parity and gravidity with metabolic syndrome was confined to pre-menopausal women (Ptrend <0.01). Among the components of metabolic syndrome only high blood pressure showed positive association with parity and gravidity (Ptrend = 0.01 and <0.001). Neither Parity nor gravidity was appreciably associated with other components of metabolic syndrome. Conclusions Multi parity or gravidity may be a risk factor for metabolic syndrome. PMID:23936302

    The age of adiposity rebound (AR) is defined as the time at which BMI starts to rise after infancy and is thought to be a marker of later obesity. To determine whether this age is related to future occurrence of metabolic syndrome, we investigated the relationship of the timing of AR with metabolic consequences at 12 years of age. A total of 271 children (147 boys and 124 girls) born in 1995 and 1996 were enrolled in the study. Serial measurements of BMI were conducted at the ages of 4 and 8 months and 1, 1.5, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, and 12 years, based on which age of AR was calculated. Plasma lipids and blood pressure were measured at 12 years of age. An earlier AR (<4 years of age) was associated with a higher BMI (≥ 20) and a lipoprotein phenotype representative of insulin resistance. This phenotype consists of elevated triglycerides, apolipoprotein B, and atherogenic index and decreased high-density lipoprotein cholesterol in boys and elevated apolipoprotein B in girls at 12 years of age. The earlier AR was also related to elevated blood pressure in boys. This longitudinal population-based study indicates that children who exhibit AR at a younger age are predisposed to future development of metabolic syndrome. Therefore, monitoring of AR may be an effective method for the early identification of children at risk for metabolic syndrome.

    Obesity symbolizes a major public health problem. Overweight and obesity are associated to the occurrence of the metabolic syndrome and to adipose tissue dysfunction. The adipose tissue is metabolically active and an endocrine organ, whose dysregulation causes a low-grade inflammatory state and ectopic fat depositions. The Mediterranean Diet represents a possible therapy for metabolic syndrome, preventing adiposopathy or “sick fat” formation. The Mediterranean Diet exerts protective effects in elderly subjects with and without baseline of chronic diseases. Recent studies have demonstrated a relationship between cancer and obesity. In the US, diet represents amount 30-35% of death causes related to cancer. Currently, the cancer is the second cause of death after cardiovascular diseases worldwide. Furthermore, populations living in the Mediterranean area have a decreased incidence of cancer compared with populations living in Northern Europe or the US, likely due to healthier dietary habits. The bioactive food components have a potential preventive action on cancer. The aims of this review are to evaluate the impact of Mediterranean Diet on onset, progression and regression of metabolic syndrome, cancer and on longevity. PMID:27894098

    To evaluate the influence of metabolic syndrome in the effectiveness of antihypertensive treatment and to compare it using the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATP III) (2001 and 2004), International Diabetes Federation (IDF) and American Heart Association/National Heart, Lung and Blood Institute (AHA-NHLBI) definitions. The VALSIM (Estudo de Prevalência da Síndrome Metabólica) survey was designed as an observational cross-sectional study performed in a primary healthcare setting in Portugal. The first two adult patients scheduled for an appointment on a given day were invited to participate. The treatment effectiveness was evaluated by the occurrence of uncontrolled hypertension (≥140/90 mmHg) in patients taking antihypertensive drugs. Logistic regression analysis was used to determine the association between uncontrolled hypertension and metabolic risk factors, with adjustments for age, sex, and pattern of antihypertensive treatment. Among the 16,856 individuals evaluated, 8925-treated hypertensive patients were identified. Only 35.8% of them had controlled hypertension. The risk of poor blood pressure control increased with age, waist circumference, serum levels of triglycerides and HDL-cholesterol. Among treatable risk factors, metabolic syndrome as defined by NCEP-ATP III 2001 diagnostic criteria was the strongest independent predictor of uncontrolled hypertension (odds ratio: 1.23; 95% CI: 1.08-1.41; P=0.002). In opposition, the IDF or AHA-NHLBI definitions of metabolic syndrome failed to identify patients at risk of poor blood pressure control. Metabolic syndrome is associated with lower effectiveness of antihypertensive therapy and the NCEP-ATP III 2001 definition of metabolic syndrome is the one that better identifies patients at risk of poor blood pressure control.

    Introduction Dementia caregivers have an increased risk of cardiovascular disease (CVD), and it is possible that metabolic disturbances contribute to this risk. Regular physical exercise reduces cardiometabolic risk, but caregivers may have less opportunity to engage in such activity. We hypothesized that regular physical activity would moderate cardiometabolic risk in dementia caregivers. Methods 115 Alzheimer’s caregivers and 54 non-caregiving controls were assessed for medical history and health habits. Physical activity was defined as the number of days per week participants performed light (score 0–4), moderate (score 0–4), or vigorous (score 0–4) exercise (total score 0–12). A cardiometabolic risk score was calculated by adding standardized z-scores of five metabolic syndrome (MetS) components: body mass index, triglycerides, high-density lipoprotein cholesterol, systolic blood pressure and glucose. Results Caregivers were less physically active than non-caregivers (5.1±3.0 vs. 6.3±2.7, p=0.008). A significant caregiver status-by-physical activity interaction was found for the standardized cardiometabolic risk score controlling for gender, age, education, smoking, alcohol consumption, health problems, cholesterol-lowering medication, negative affect, role overload, and fasting state (p=0.035). Among participants with low levels of physical activity, caregivers had greater cardiometabolic risk score than non-caregivers (0.58±0.31 vs. −1.23±0.54, p=0.017); no group difference emerged in participants with high levels of physical activity (p=0.81). Conclusions Cardiometabolic risk was particularly high in caregivers reporting reduced level of regular physical activity. Intervention studies aimed at increasing physical activity in caregivers seem warranted to examine whether that would possibly lower cardiometabolic risk to the level of non-caregivers.

The literature search has been carried out using the key words "insulin resistance, the metabolic syndrome, cardiovascular risk, diabetes, obesity, Asian Indians, and South Asians" in the medical search engine Pubmed (National Library of Medicine, Bethesda, MD) from 1966 to September 2009. A high prevalence of the metabolic syndrome and associated cardiovascular risk factors has been observed not only in urban South Asian/Asian Indian adults and children but also in economically disadvantaged people residing in urban slums and rural areas. The main drivers are rapid nutrition, lifestyle, and socioeconomic transitions, consequent to increasing affluence, urbanization, mechanization, and rural-to-urban migration. Less investigated determinants of the metabolic syndrome include psychological stress in urban setting, genetic predisposition, adverse perinatal environment, and childhood "catch up" obesity. Data show atherogenic dyslipidemia, glucose intolerance, thrombotic tendency, subclinical inflammation, and endothelial dysfunction are higher in South Asians than Caucasians. Many of these manifestations are more severe and are seen at an early age (childhood) in South Asians than Caucasians. Metabolic syndrome and cardiovascular risk in South Asians is also heightened by their higher body fat, truncal subcutaneous fat, intra-abdominal fat, and ectopic fat deposition (liver fat, etc.). Further, cardiovascular risk cluster manifests at a lower level of adiposity and abdominal obesity. The cutoffs of body mass index and waist circumference for defining obesity and abdominal obesity, respectively, have been lowered and the definition of the metabolic syndrome has been revised for Asian Indians in a recent consensus statement, so that

    Metabolic disease results from a complex interaction of many factors, including genetic, physiological, behavioral and environmental influences. The recent rate at which these diseases have increased suggests that environmental and behavioral influences, rather than genetic causes, are fuelling the present epidemic. In this context, the developmental origins of health and disease hypothesis has highlighted the link between the periconceptual, fetal and early infant phases of life and the subsequent development of adult obesity and the metabolic syndrome. Although the mechanisms are yet to be fully elucidated, this programming was generally considered an irreversible change in developmental trajectory. Recent work in animal models suggests that developmental programming of metabolic disorders is potentially reversible by nutritional or targeted therapeutic interventions during the period of developmental plasticity. This review will discuss critical windows of developmental plasticity and possible avenues to ameliorate the development of postnatal metabolic disorders following an adverse early life environment.

    Metabolic Syndrome (METs) definitions vary and diagnosis takes into account consumption of medications commonly prescribed for conditions defining METs. This paper evaluates the potential differences in population characteristics using two different methods of defining METs, with and without the adjustment of the effects of pharmacotherapy on biochemical and blood pressure (BP) measurements Methods: This was a cross-sectional study utilizing the Malaysian Elders Longitudinal Research (MELoR) cohort comprising urban community-dwellers aged ≥55 years. Participants were interviewed using a structured questionnaire during home visits where medications were reviewed. Health impacts assessed included heart disease, stroke, body mass index (BMI), peptic ulcers, arthritis, and number of medications and comorbidities. Risk factors and health impacts associated with METs were determined by Poisson multivariate regression models using a binary and count dependent variables. A total of 891 participants with a mean (SD) age of 68.6 (7.3) years were included. The prevalence of METs vary from 52.7% to 35.1% depending upon the definition used. The risk factors associated with METs were increasing age, ethnicity, lower education levels, BMI, stroke and medication use. Male gender was considered a risk factor following modification for medication usage using a count model. The drug-modified model removed marginal candidates prescribed medications used for specific conditions which defined METs who did not meet the criteria once their BP or biochemical parameters were modified for the effects of medication-use. The IDF definition for METs that makes allowance for treatment for each specific condition can lead to an overestimation in the prevalence of METs in population studies. Not including those medicated with normal results conversely underestimates the prevalence of METs. We have therefore proposed adjustments to BP and lipid measurements based on pooled mean effects from

    To investigate the influence of metabolic syndrome on prostate-specific antigen levels by considering prostate volume and plasma volume. We retrospectively analyzed 4111 men who underwent routine check-ups including prostate-specific antigen and transrectal ultrasonography. The definition of metabolic syndrome was based on the modified Adult Treatment Panel III criteria. Prostate-specific antigen mass density (prostate-specific antigen × plasma volume / prostate volume) was calculated for adjusting plasma volume and prostate volume. We compared prostate-specific antigen and prostate-specific antigen mass density levels of participants with metabolic syndrome (metabolic syndrome group, n = 1242) and without metabolic syndrome (non-prostate-specific antigen metabolic syndrome group, n = 2869). To evaluate the impact of metabolic syndrome on prostate-specific antigen, linear regression analysis for the natural logarithm of prostate-specific antigen was used. Patients in the metabolic syndrome group had significantly older age (P < 0.001), larger prostate volume (P < 0.001), higher plasma volume (P < 0.001) and lower mean serum prostate-specific antigen (non-metabolic syndrome group vs metabolic syndrome group; 1.22 ± 0.91 vs 1.15 ± 0.76 ng/mL, P = 0.006). Prostate-specific antigen mass density in the metabolic syndrome group was still significantly lower than that in the metabolic syndrome group (0.124 ± 0.084 vs 0.115 ± 0.071 μg/mL, P = 0.001). After adjusting for age, prostate volume and plasma volume using linear regression model, the presence of metabolic syndrome was a significant independent factor for lower prostate-specific antigen (prostate-specific antigen decrease by 4.1%, P = 0.046). Prostate-specific antigen levels in patients with metabolic syndrome seem to be lower, and this finding might be affected by the prostate volume. © 2016 The Japanese Urological Association.

    Night and shift work might be risk factors for metabolic and cardiovascular disorders due to interference with diet, circadian metabolic rhythms, and lifestyle. The relationship between permanent night work and metabolic and cardiovascular risk factors was explored in a retrospective longitudinal study of workers employed in a large municipal enterprise in charge of street cleaning and domestic waste collection. All subjects who had worked night shifts between 1976 and 2007 as hand sweepers, motor sweepers, and delivery tricar drivers were compared with subjects who always worked the same jobs but on day shifts. From the periodical medical surveillance files, we identified 488 male workers who had been examined on average five times (minimum 2, maximum 14) during the study period, for a total of 2,328 medical examinations; 157 always had worked day shifts, 12 always the night shift, and 319 both (initially day and subsequently night shifts). Their age ranged from 22 to 62 yrs, and work experience varied from 1 to 28 yrs. Lifestyle habits (smoking, alcohol consumption), body mass index, serum glucose, total cholesterol, tryglicerides, hepatic enzymes, blood pressure, resting electrocardiogram, diabetes, coronary heart disease, hypertension, and related drugs were taken into consideration for the analysis. We used generalized estimating equations (GEE) models (exchangeable correlation matrix) to analyze the relationship between night work and health effects while accounting for within-subject correlations and adjusting for study period, job, age, and lifestyle variables. As a whole, night workers smoked more and had significantly higher BMI, serum total cholesterol, and triglycerides than day workers. Both the inter-individual comparison between day and night workers and the intra-individual comparison among the workers, who were day workers at the beginning of their employment and later became night workers, showed a significant increase in BMI, total cholesterol

    To examine the pathophysiologic mechanisms that may link circadian disorder and metabolic syndrome in bipolar disorder (BP). A systematic review of the literature was conducted from January 2013 to January 2015, using the Medline and Cochrane databases, using the keywords "metabolic syndrome", "obesity", "leptin" and "circadian disorders", "sleeping disorders" and cross-referencing them with "bipolar disorder". The following types of publications were candidates for review: (i) clinical trials; (ii) studies involving patients diagnosed with bipolar disorder; (iii) studies involving patients with sleeping disorder; or (iv) data about metabolic syndrome. Forty articles were selected. The prevalence of metabolic syndrome in BP was significantly higher compared to the general population (from 36 to 49% in the USA [Vancampfort, 2013]), and could be explained by several factors including reduced exercise and poor diet, genetic vulnerability, frequent depressive episodes, psychiatric comorbidity and psychotropic treatment. This high frequency of metabolic syndrome worsens the prognosis of these patients, increasing morbidity and mortality. Secondly, patients with BP experienced circadian and sleep disturbance, including modification in melatonin secretion. These perturbations are known to persist in periods of mood stabilization and are found in patients' relatives. Circadian disturbances are factors of relapse in bipolar patients, and they may also have a role in the metabolic comorbidities of these patients. Recent studies show that in populations of patients with bipolar disorder, a correlation between circadian disturbance and metabolic parameters are found. To identify the pathophysiological pathway connecting both could lead to a better comprehension of the disease and new therapeutics. In the overall population, mechanisms have been identified linking circadian and metabolic disorder involving hormones like leptin and ghrelin. These hormones are keys to

    There are three commonly used definitions of the metabolic syndrome, making scientific studies hard to compare. The aim of this study was to investigate agreement in the prevalence of the metabolic syndrome defined by three different definitions and to analyze definition and gender differences. A population-based, cross-sectional study of a total of 4232 participants--2039 men and 2193 women, aged 60 years--was employed. Three different metabolic syndrome definitions were compared: European Group for the Study of Insulin Resistance (EGIR), International Diabetes Federation (IDF), and National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III). Medical history, socioeconomic information, and lifestyle data were collected by a questionnaire. A medical examination including laboratory tests was performed. Significant factors for the metabolic syndrome were calculated by multivariate logistic regression. Forty five percent of men and 30% of women met the criteria for the metabolic syndrome by any definition, but only 17% of men and 9% of women met the criteria of all three definitions. The highest agreement was found between IDF and NCEP ATP III definition. Two significant associations were identified in both men and women by the three metabolic syndrome definitions; former smokers were highly associated with the metabolic syndrome (odds ratio [OR] congruent with 1.5), and regular physical activity (OR congruent with 0.6) was inversely associated with the metabolic syndrome. Depending on the definition used, different individuals were identified as having the metabolic syndrome, which affects the reliability of interpretations to be made from scientific studies of the metabolic syndrome. Unified criteria are warranted. Physicians facing a physically inactive former smoker may consider diagnosing metabolic syndrome.

    Polycystic ovary syndrome (PCOS) is a common condition in women at reproductive age associated with reproductive and metabolic dysfunction. Proposed diagnosed criteria for PCOS include two out of three features: androgen excess, menstrual irregularity, and polycystic ovary appearance on ultrasound (PCO), after other causes of hyperandrogenism and dysovulation are excluded. Based on these diagnostic criteria, the most common phenotypes are the "classic PCOS"--hyperandrogenism and oligomenorrhea, with or without PCO; the "ovulatory phenotype"--hyperandrogenism and PCO in ovulatory women; and the "non-hyperandrogenic phenotype", in which there is oligomenorrhea and PCO, without overt hyperandrogenism. The presence of obesity may exacerbate the metabolic and reproductive disorders associated with the syndrome. In addition, PCOS women present higher risk for type 2 diabetes and higher prevalence of cardiovascular risk factors that seems to be associated with the classic phenotype. The main interventions to minimize cardiovascular and metabolic risks in PCOS are lifestyle changes, pharmacological therapy, and bariatric surgery. Treatment with metformin has been shown to improve insulin sensitivity, lowering blood glucose and androgen levels. These effects are more potent when combined with lifestyle interventions. In conclusion, besides reproductive abnormalities, PCOS has been associated to metabolic comorbidities, most of them linked to obesity. Confounders, such as the lack of standard diagnostic criteria, heterogeneity of the clinical presentation, and presence of obesity, make management of PCOS difficult. Therefore, the approach to metabolic abnormalities should be tailored to the risks and treatment goals of each individual woman.

    Not only the obese, but also the non-obese adults have the high prevalence of metabolic syndrome in the upper normal weight. The aim of this study was to assess the prevalence rates of metabolic syndrome and its individual components in non-obese adult Taiwanese (body mass index (BMI) metabolic syndrome, defined by the American Heart Association/National Heart, Lung and Blood Institute (2005), were analyzed in the BMI category according to 2.0 unit increments, in individuals seeking a health examination. The higher the BMI categories, the more prevalent the metabolic syndrome was in women and in men (P < 0.001). Compared with those women with a BMI metabolic syndrome in women were 1.3 (95%CI: 0.5 - 3.2) with BMI 21.0 - 22.9 kg/m(2), 3.0 (1.3 - 7.1) with BMI 23.0 - 24.9 kg/m(2), and 8.6 (3.6 - 20.8) for women with BMI 25.0 - 26.9 kg/m(2), after controlling for age, smoking status, alcohol consumption, betel nut chewing, blood routine, biochemical data, hepatitis B virus surface antigen and anti-hepatitis C virus. The corresponding odds ratios in men were 1.6 (0.6 - 4.2), 3.7 (1.6 - 8.8), and 9.9 (4.2 - 23.2). Individuals in the upper normal weight and slightly overweight BMI range have relatively high prevalence and increased risk of having metabolic syndrome. Therefore, physicians should screen metabolic syndrome in not only obese but also non-obese individuals for the prevention of cardiovascular disease.

    Sub-Saharan Africa bears an inordinate burden of human immunodeficiency virus (HIV) infection/acquired immune deficiency syndrome (AIDS). Reports have shown increased prevalence of clustering of cardiovascular risk factors referred to as metabolic syndrome in treatment-naïve patients and patients on highly active antiretroviral therapy (HAART). In view of the fact that metabolic syndrome is a heterogeneous disorder with substantial variability in the prevalence and component traits within and across populations and the dearth of publications on the prevalence and clinical correlates of metabolic syndrome in people living with HIV/AIDS (PLWHA) in Nigeria, this study was carried out to determine the prevalence and clinical correlates of metabolic syndrome among an HIV-infected outpatient population using the National Cholesterol Education Adult Treatment Panel III (NCEP ATP III), the International Diabetes Federation (IDF), and the Joint Interim Statement (JIS) definitions. We also sought to determine if HAART use and CD4 count level were associated with metabolic syndrome. This cross-sectional study involved 291 (95 men, 196 women) consecutive PLWHA. Anthropometry, blood pressure, fasting plasma glucose, and lipid profile values were determined. The prevalence rates of metabolic syndrome according to the ATP III, IDF, and JIS criteria were 12.7%, 17.2%, and 21.0%, respectively. Metabolic syndrome was significantly associated with female gender (all definitions), body mass index (all definitions), increasing age, and CD4 count (IDF definition). There was no significant association between metabolic syndrome and HAART. The concordance [kappa coefficient (κ)] between the definitions of metabolic syndrome varied between 0.583 and 0.878. The prevalence of metabolic syndrome varied with the criteria used and metabolic syndrome correlates with traditional cardiovascular risk factors rather than HAART-related factors.

    Emerging evidence has assigned an important role to sleep as a modulator of metabolic homeostasis. The impact of variations in sleep duration, sleep-disordered breathing, and chronotype to cardiometabolic function encompasses a wide array of perturbations spanning from obesity, insulin resistance, type 2 diabetes, the metabolic syndrome, and cardiovascular disease risk and mortality in both adults and children. Here, we critically and extensively review the published literature on such important issues and provide a comprehensive overview of the most salient pathophysiologic pathways underlying the links between sleep, sleep disorders, and cardiometabolic functioning.

    Binary definitions of the metabolic syndrome based on the presence of a particular number of individual risk factors are limited, particularly in the pediatric population. To address this limitation, we aimed at constructing composite and continuous metabolic syndrome scores (cmetS) to represent an overall measure of metabolic syndrome (MetS) in a large cohort of metabolically at-risk children, focusing on the use of the usual clinical parameters (waist circumference (WC) and systolic blood pressure (SBP), supplemented with two salivary surrogate variables (glucose and high density lipoprotein cholesterol (HDLC). Two different approaches used to create the scores were evaluated in comparison. Data from 8,112 Kuwaiti children (10.00 ± 0.67 years) were used to construct two cmetS for each subject. The first cmetS (cmetS-Z) was created by summing standardized residuals of each variable regressed on age and gender; and the second cmetS (cmetS-PCA) was defined as the first principal component from gender-specific principal component analysis based on the four variables. There was a graded relationship between both scores and the number of adverse risk factors. The areas under the curve using cmetS-Z and cmetS-PCA as predictors for severe metabolic syndrome (defined as the presence of ≥3 metabolic risk factors) were 0.935 and 0.912, respectively. cmetS-Z was positively associated with WC, SBP, and glucose, but inversely associated with HDLC. Except for the lack of association with glucose, cmetS-PCA was similar to cmetS-Z in boys, but had minimum loading on HDLC in girls. Analysis using quantile regression showed an inverse association of fitness level with cmetS-PCA (p = 0.001 for boys; p = 0.002 for girls), and comparison of cmetS-Z and cmetS-PCA suggested that WC and SBP were main contributory components. Significant alterations in the relationship between cmetS and salivary adipocytokines were demonstrated in overweight and obese children as compared to

    Epidemiological studies have suggested that metabolic programming begins during fetal life and adverse events in utero are a critical factor in the etiology of chronic diseases and overall health. While the underlying molecular mechanisms linking impaired fetal development to these adult diseases are being elucidated, little is known about how we can intervene early in life to diminish the incidence and severity of these long-term diseases.

    Abstract Increased prevalence of metabolic syndrome was found in patients with schizophrenia. Brain-derived neurotrophic factor (BDNF) was involved in energy metabolism and the pathophysiology of schizophrenia, but differently in males and females. We aimed to investigate the serum BDNF levels in patients with schizophrenia with and without metabolic syndrome. Patients with schizophrenia were recruited. Their demographic data were collected. Metabolic profiles and serum BDNF levels were measured. Clinical symptoms were evaluated with Positive and Negative Syndrome Scale. Metabolic syndrome was determined with the criteria provided by Ministry of Health and Welfare of Taiwan. Framingham Risk Score (FRS) for estimate of 10-year risk for coronary heart disease was provided by National Institutes of Health. Of the 81 participants, 40.7% had metabolic syndrome. Those with metabolic syndrome had higher FRS. Using analysis of covariance adjusted for age and body mass index, male patients with schizophrenia with metabolic syndrome had higher serum BDNF levels than those without (4.6 ± 4.7 vs 3.3 ± 3.8 ng/mL, P = .022). No statistical difference was found between female patients with and without metabolic syndrome. Significant differences of serum BDNF levels were found between male patients with schizophrenia with and without metabolic syndrome, but not in females. This finding suggested the gender difference behind the mechanism of BDNF in metabolic syndrome in schizophrenia. PMID:28562580

    The present study examined caregivers' preferences for intervention strategies in dealing with the dilemma of respecting autonomy of intellectually disabled persons versus providing high-quality care. Twenty-four parents and 14 professional caregivers of persons with Prader-Willi syndrome were asked to rate four different kinds of intervention strategies according to their preferred way of dealing with 8 presented cases. In general, caregivers preferred to intervene more actively in eating problems compared to behavioural problems, more in acute than in chronic situations, and more in situations at home than in community-based settings. Significant differences were found between parents and professionals. Parents and professionals prefer intervening above laissez-faire. Parents prefer active intervention stronger than professionals. Awareness of various intervention strategies can help caregivers to develop a practice that does justice to the need for intervention on the one hand, and the possibility of using a variety of intervention strategies on the other hand. Communication about intervention strategies might foster understanding between professional caregivers and parents and improve mutual cooperation.

    Despite the lack of international agreement regarding the definition and classification of fiber, there is established evidence on the role of dietary fibers in obesity and metabolic syndrome. Beta glucan (β-glucan) is a soluble fiber readily available from oat and barley grains that has been gaining interest due to its multiple functional and bioactive properties. Its beneficial role in insulin resistance, dyslipidemia, hypertension, and obesity is being continuously documented. The fermentability of β-glucans and their ability to form highly viscous solutions in the human gut may constitute the basis of their health benefits. Consequently, the applicability of β-glucan as a food ingredient is being widely considered with the dual purposes of increasing the fiber content of food products and enhancing their health properties. Therefore, this paper explores the role of β-glucans in the prevention and treatment of characteristics of the metabolic syndrome, their underlying mechanisms of action, and their potential in food applications.

    Nonalcoholic fatty liver disease (NAFLD) is considered the most common cause of chronic liver disease in the Western countries. NAFLD includes a spectrum ranging from a simple steatosis to a nonalcoholic steatohepatitis (NASH) which is defined by the presence of inflammatory infiltrate, cellular necrosis, hepatocyte ballooning, and fibrosis and cirrhosis that can eventually develop into hepatocellular carcinoma. Studies emphasize the role of insulin resistance, oxidative stress, pro-inflammatory cytokines, adipokines in the development and progression of NAFLD. It seems to be independently associated with type II diabetes mellitus, increased triglycerides, decreased HDL-cholesterol, abdominal obesity and insulin resistance. These findings are in accordance with the criteria used in the diagnosis of metabolic syndrome (MetS). Here, we will discuss the current knowledge on the epidemiology, pathophysiology and diagnosis of NAFLD and the association of metabolic syndrome in postmenopausal women.

    Cardiovascular disease risk rises sharply with menopause, likely due to the coincident increase in insulin resistance and related atherogenic changes that together comprise the metabolic or insulin resistance syndrome, a cluster of metabolic and hemodynamic abnormalities strongly implicated in the pathogenesis and progression of cardiovascular disease. A growing body of research suggests that traditional mind-body practices such as yoga, tai chi, and qigong may offer safe and cost-effective strategies for reducing insulin resistance syndrome-related risk factors for cardiovascular disease in older populations, including postmenopausal women. Current evidence suggests that these practices may reduce insulin resistance and related physiological risk factors for cardiovascular disease; improve mood, well-being, and sleep; decrease sympathetic activation; and enhance cardiovagal function. However, additional rigorous studies are needed to confirm existing findings and to examine long-term effects on cardiovascular health. PMID:18779682

    As older patients present with an average of three comorbidities beside their cancer, geriatric oncology can provide unique clues to translational research in aging and cancer. We illustrate this approach with the example of the metabolic syndrome and cancer. Epidemiologic and clinical cohorts highlighted an association between the metabolic syndrome and a higher risk and worse prognosis of various cancers. In a bedside-to-bench transition, this led to an interest in analyzing the potential mechanisms underlying this association. At least ten potential mechanisms could be implicated, with the challenge of understanding which are the dominant ones in human patients. Bench-to-bedside studies are beginning to shed some light on that aspect, and some therapeutic trials are beginning to exploit the lessons learned. Copyright © 2013 S. Karger AG, Basel.

    Increasing numbers of long-term cancer survivors face important treatment related adverse effects. Cancer treatment induced metabolic syndrome (CTIMetS) is an especially prevalent and harmful condition. The aetiology of CTIMetS likely differs from metabolic syndrome in the general population, but effective treatment and prevention methods are probably similar. In this review, we summarize the potential mechanisms leading to the development of CTIMetS after various types of cancer treatment. Furthermore, we propose a safe and accessible method to treat or prevent CTIMetS through lifestyle change. In particular, we suggest that a lifestyle intervention and optimization of energy balance can prevent or mitigate the development of CTIMetS, which may contribute to optimal survivorship care.

    Obesity is one of the major public health problems worldwide. It is a chronic, complex, and multifactorial origin disease characterised by body fat excess mainly due to an imbalance between dietary intake and energy expenditure. One of the major complications of obesity is metabolic syndrome, which comprises anthropometrical, clinical, and metabolic dysfunctions that predispose the affected individual to the development of type 2 diabetes mellitus and cardiovascular diseases. It is hypothesised that the variability in the susceptibility to obesity-mediated metabolic complications involves both environmental and genetic factors. Whereas advances in the knowledge of the variations in the human genome have led to the identification of susceptibility genes that contribute to obesity and related disorders, relatively few studies have specifically focused on the interactions between obesity and genetic polymorphisms and the development of metabolic complications. Despite these limited efforts, an increasing amount of evidence suggests that the effects of some gene variants on metabolic traits are modified by or present only in the setting of obesity. Furthermore, some of these loci may have larger effects on metabolic phenotypes in the presence of certain dietary or lifestyle factors. In the present manuscript, we reviewed the genes and their variants that have been evidenced to play a role in obesity-associated metabolic complications through genetic association studies, including candidate gene and genome-wide association approaches in adults and children.

    Metabolic syndrome refers to a collection of risk factors associated with the development of cardiovascular disease and type 2 diabetes mellitus (T2DM). Canagliflozin, a sodium glucose co-transporter 2 inhibitor, improves glycemic control and reduces body weight and blood pressure (BP) in a broad range of patients with T2DM. This post hoc analysis assessed the effects of canagliflozin on the components of metabolic syndrome in patients with T2DM and metabolic syndrome. This analysis was based on data from 2 head-to-head studies of canagliflozin in patients with T2DM on background metformin versus glimepiride (study 1) and background metformin plus sulfonylurea versus sitagliptin 100 mg (study 2). Changes from baseline in glycemic efficacy, anthropometric measures, BP, and lipids were evaluated with canagliflozin versus glimepiride and sitagliptin at week 52 in patients who met ≥2 of the criteria for metabolic syndrome (in addition to T2DM): triglycerides ≥1.7 mmol/L; high-density lipoprotein cholesterol (HDL-C) <1.0 mmol/L (men) or <1.3 mmol/L (women); waist circumference ≥102 cm (non-Asian men), ≥88 cm (non-Asian women), >90 cm (Asian men), or >80 cm (Asian women); diagnosis of hypertension or meeting BP-related criteria (systolic BP ≥130 mmHg or diastolic BP ≥85 mmHg). Safety was assessed based on adverse event reports. In study 1, canagliflozin 100 and 300 mg provided similar and greater HbA1c reductions versus glimepiride, respectively. In study 2, canagliflozin 300 mg provided greater HbA1c lowering versus sitagliptin 100 mg. Canagliflozin also reduced fasting plasma glucose, body weight, body mass index, waist circumference, BP, and triglycerides, and increased HDL-C and low-density lipoprotein cholesterol versus glimepiride and sitagliptin. Canagliflozin was generally well tolerated in each study. Canagliflozin was associated with improvements in all components of metabolic syndrome in patients with T2DM and metabolic syndrome, whereas

    Basal forebrain cholinergic neurons play a key role in cognition. This neuronal system is highly dependent on NGF for its synaptic integrity and the phenotypic maintenance of its cell bodies. Basal forebrain cholinergic neurons progressively degenerate in Alzheimer's disease and Down's syndrome, and their atrophy contributes to the manifestation of dementia. Paradoxically, in Alzheimer's disease brains, the synthesis of NGF is not affected and there is abundance of the NGF precursor, proNGF. We have shown that this phenomenon is the result of a deficit in NGF's extracellular metabolism that compromises proNGF maturation and exacerbates its subsequent degradation. We hypothesized that a similar imbalance should be present in Down's syndrome. Using a combination of quantitative reverse transcription-polymerase chain reaction, enzyme-linked immunosorbent assay, western blotting and zymography, we investigated signs of NGF metabolic dysfunction in post-mortem brains from the temporal (n = 14), frontal (n = 34) and parietal (n = 20) cortex obtained from subjects with Down's syndrome and age-matched controls (age range 31-68 years). We further examined primary cultures of human foetal Down's syndrome cortex (17-21 gestational age weeks) and brains from Ts65Dn mice (12-22 months), a widely used animal model of Down's syndrome. We report a significant increase in proNGF levels in human and mouse Down's syndrome brains, with a concomitant reduction in the levels of plasminogen and tissue plasminogen activator messenger RNA as well as an increment in neuroserpin expression; enzymes that partake in proNGF maturation. Human Down's syndrome brains also exhibited elevated zymogenic activity of MMP9, the major NGF-degrading protease. Our results indicate a failure in NGF precursor maturation in Down's syndrome brains and a likely enhanced proteolytic degradation of NGF, changes which can compromise the trophic support of basal forebrain cholinergic neurons.

    Background. Recent studies have reported an increase in the prevalence of obesity and metabolic syndrome in children and adolescents. However, few have focused how diabetes mellitus and metabolic syndrome together in parents can influence on obesity and metabolic disturbances in offspring. Objective. To know the risk obesity and metabolic disturbance in children, adolescents, and young adults whose parents have diabetes mellitus and metabolic syndrome. Methods. A comparative survey was made in healthy children of parents with diabetes mellitus and metabolic syndrome compared with offspring of healthy parents. We performed anthropometry and evaluated blood pressure, glucose, total cholesterol, HDL cholesterol, and triglycerides levels in plasma. We registered parent antecedents to diabetes mellitus and metabolic syndrome and investigated the prevalence of overweight, obesity, and metabolic disturbances in offspring. Results. We studied 259 subjects of 7 to 20 years of age. The prevalence of overweight and obesity was 27% and 37%, respectively. The highest proportion of BMI >95th of the entire group was found in offspring with both diabetic parents. Glucose and total cholesterol levels were lower in the group with healthy parents compared with the group with diabetic mother and metabolic syndrome but with healthy father. HDL cholesterol was higher in the group with both healthy parents than in the group with diabetic mother and metabolic syndrome but healthy father. Conclusions. The offspring of parents with diabetes plus metabolic syndrome showed higher proportion of variables related to metabolic syndrome compared with healthy parents. PMID:23193389

    AIM: To investigate the effect of novel probiotics on the clinical characteristics of high-fructose induced metabolic syndrome. METHODS: Male Wistar rats aged 4 wk were fed a 70% w/w high-fructose diet (n = 27) or chow diet (n = 9) for 3 wk to induce metabolic syndrome, the rats were then randomized into groups and administered probiotic [Lactobacillus curvatus (L. curvatus) HY7601 and Lactobacillus plantarum (L. plantarum) KY1032] at 109 cfu/d or 1010 cfu/d or placebo by oral gavage for 3 wk. Food intake and body weight were measured once a week. After 6 wk, the rats were fasted for 12 h, then anesthetized with diethyl ether and sacrificed. Blood samples were taken from the inferior vena cava for plasma analysis of glucose, insulin, C-peptide, total-cholesterol, triglycerides and thiobarbituric acid-reacting substances. Real-time polymerase chain reaction was performed using mouse-specific Taqman probe sets to assess genes related to fatty acid β-oxidation, lipogenesis and cholesterol metabolism in the liver. Target gene expression was normalized to the housekeeping gene, glyceraldehyde-3-phosphate dehydrogenase. RESULTS: Rodents fed a high-fructose diet developed clinical characteristics of the metabolic syndrome including increased plasma glucose, insulin, triglycerides, total cholesterol and oxidative stress levels, as well as increased liver mass and liver lipids compared to chow fed controls. Probiotic treatment (L. curvatus HY7601 and L. plantarum KY1032) at high (1010 cfu/d) or low dosage (109 cfu/d) lowered plasma glucose, insulin, triglycerides and oxidative stress levels. Only high-dose probiotic treatment reduced liver mass and liver cholesterol. Probiotic treatment reduced lipogenesis via down-regulation of SREBP1, FAS and SCD1 mRNA levels and increased β-oxidation via up-regulation of PPARα and CPT2 mRNA levels. CONCLUSION: Probiotic L. curvatus HY7601 and L. plantarum KY1032 combined suppressed the clinical characteristics of high

    We performed a systematic review and meta-analysis on the association of metabolic syndrome with endometrial cancer. A systematic literature search of electronic databases (Medline, ISI Web of Knowledge and Scopus) was conducted and complemented by cross-referencing to identify studies published before 31 January 2013. Core items of identified studies were independently extracted by two reviewers, and results were summarized by random effects meta-analysis. We identified six studies, which reported on 3,132 cancer cases. Metabolic syndrome was associated with an increased risk of endometrial cancer (RR: 1.89, 95 % CI 1.34-2.67, P < 0.001), with significant heterogeneity among studies (I (2) = 92 %, P < 0.001), but no indication for publication bias in the Egger's test (P = 0.240). A sensitivity analysis omitting two studies produced no heterogeneity (I (2) = 0 %) and attenuated the association (RR: 1.39, 1.31-1.48, P < 0.001). The risk estimates for any single factor of the syndrome were 2.21 (P < 0.001) for higher values of body mass index and/or waist, 1.81 (P = 0.044) for hyperglycemia, 1.81 (P = 0.024) for higher blood pressure values, and 1.17 (P < 0.001) for high triglyceride levels; there was no significant association with low HDL-cholesterol. Metabolic syndrome is associated with an increased risk of endometrial cancer; among the components of the syndrome, obesity/high waist is that more strongly associated with endometrial cancer.

Although phenotypes were different, high triglycerides and fasting dysglycemia were good predictors of MetS in all three groups using both definitions. The international cut-offs for abdominal obesity were not predictive of MetS in the Haitian subjects.

This short review will be aimed at focusing and discussing the new information collected on two specific clinical conditions such as obesity and metabolic syndrome. The paper will briefly describe the four main mechanisms that represent the common link between these two pathophysiological conditions and that through the sympathetic nervous system contribute to increase the cardiovascular risk.

Their beneficial effects can be explained partly by their effects on lipoproteins,but these effects may also result from some of their nonlipid pleotropic effects. Clinical trials are still needed to determine the potential role played by such pleotropic actions.

    Metabolic syndrome is linked to increased cardiovascular mortality, which may be partially attributed to cardiac sympatho-vagal imbalance. However, autonomic changes were not evaluated during the metabolic syndrome development in a monosodium glutamate-induced animal model. We evaluate temporal changes in cardiovascular autonomic modulation in an animal model of metabolic syndrome. Eighteen neonate male spontaneously hypertensive rats (SHR) were treated with monosodium glutamate (MetS), and compared with Wistar-Kyoto (C) and saline-treated SHR (H). Lee index, insulin resistance and autonomic control (spectral analysis) were evaluated at 3 (3-mo), 6 (6-mo) and 9 (9-mo) months of age (compared by two-way ANOVA, p<0.05). Weight of visceral fat, Lee index and arterial pressure were higher in the MetS vs. C and H groups (p<0.001) at all ages. Heart rate variability (HRV) was decreased in the MetS and H groups at 3-mo and 9-mo vs. C. The LF component of HRV was reduced in the MetS group at 3-mo vs. C (p=0.032), and higher vs. C and H at 9-mo (p<0.001, all comparisons). H and MetS rats had a higher LF/HF index vs. C at 9-mo (p=0.001, all comparisons). The VLF component of systolic arterial pressure variability of the MetS was higher earlier (6-mo) than that of the H group. A reduction of 70%, 98% and 54% in αLF index of H and MetS rats vs. C, was observed at 3, 6 and 9 months, respectively. Metabolic syndrome and hypertension in rats evolve with progressive autonomic dysfunction (worst at 9 months), with specific derangements occurring very early.

    To assess the relationship between prostate cancer (PC) and the presence of metabolic syndrome and late-onset hypogonadism (LOH) syndrome. A retrospective study was conducted on 686 patients who underwent prostate biopsy. We analysed the demographic variables, clinical data and biopsy results. To diagnose metabolic syndrome, we employed the criteria of the American Heart Association. For the diagnosis of LOH syndrome, we employed the Androgen Deficiency in the Aging Male questionnaire and testosterone levels (TT). We evaluated the relationship between free testosterone (FT) and bioavailable testosterone (BT) on one hand and PC and its aggressiveness on the other, as well as the usefulness of the TT to prostate specific antigen (TT/PSA) ratio in the PC diagnosis. The patient's median age was 65 years. Metabolic syndrome is not associated with PC (39.4% vs. 35%; P=.1) but is associated with a PC Gleason score >7 (50.4% vs. 29.44%; P=.002). LOH, low FT and low BT are associated with an increased presence of PC (51% vs. 35%, P=.02; 44.86% vs. 33.33%, P=.03; and 46.46% vs. 33.08%, P=.01, respectively) and with an increased probability of a PC Gleason score >7 (61.54% vs. 37.5%, P=.02; 54.17% vs. 34.12%, P=.02; 54.35% vs. 34.48%, P=.02, respectively). Additionally, the median TT/PSA ratio was significantly lower in patients with positive biopsies (P=.022). Metabolic syndrome was not associated with the probability of having PC but was associated with a PC Gleason score >7. Moreover, LOH syndrome had a higher percentage of PC and a greater presence of PC Gleason scores >7, as did low levels of FT and low levels of BT. Copyright © 2016 AEU.

    The prevalence of atrial fibrillation (AF) and AF-related stroke is set to increase dramatically in coming decades, with developing regions such as Latin America experiencing the greatest impact. These trends are primarily driven by aging populations and by the increasing prevalence of the metabolic syndrome. The metabolic syndrome describes an association between diabetes, hypertension, obesity, and dyslipidemia and an increased risk of cardiovascular disease. It is in large part the result of unbalanced diet and sedentary lifestyle. These essentially modifiable risk factors are becoming more prevalent with the widespread adoption of so-called Western lifestyles. This review examines the physiology underlying the link between the metabolic syndrome and AF. Next, it highlights the importance of addressing lifestyle-related risk factors to mitigate the trend toward increasing AF prevalence. It then goes on to discuss the importance of stroke prevention therapy in patients with established AF, focusing on the relative merits of various available options for anticoagulation. Given the recent availability of comprehensive data on the 4 currently available non-vitamin K antagonist oral anticoagulant drugs, this review concludes by discussing the relative merits of specific agents in individual patient groups.

    Metabolic syndrome is a complex disorder caused by a cluster of interrelated factors that increases the risk of cardiovascular diseases and type 2 diabetes. Obesity is the main precursor for metabolic syndrome that can be targeted in developing various therapies. With this view, several physical, psychological, pharmaceutical and dietary therapies have been proposed for the management of obesity. However, dietary strategies found more appropriate without any adverse health effects. Application of probiotics and prebiotics as biotherapeutics is the new emerging area in developing dietary strategies and many people are interested in learning the facts behind these health claims. Recent studies established the role of probiotics and prebiotics in weight management with possible mechanisms of improved microbial balance, decreased food intake, decreased abdominal adiposity and increased mucosal integrity with decreased inflammatory tone. Hence, the above "Pharmaco-nutritional" approach has been selected and extensively reviewed to gain thorough knowledge on putative mechanisms of probiotic and prebiotic action in order to develop dietary strategies for the management of metabolic syndrome.

    The metabolic syndrome (MS) recognized as a major cause of type 2 diabetes and cardiovascular diseases, has become one of the major public health challenges worldwide. The pathogenesis of the metabolic syndrome is multiple and still poorly understood. No single factor has yet been identified as an underlying causal factor. There is a growing belief, however, that obesity, especially visceral obesity, may play an important role in the development of the syndrome. Visceral adiposity seems to be an independent predictor of insulin sensitivity, impaired glucose tolerance, dyslipidemia and elevated blood pressure. An increasing number of studies confirm that oxidative stress, chronic inflammation and angiogenesis all play important roles in the pathogenesis of MS. Chronic hyperglycemia causes oxidative stress in tissues prone to complications in patients with diabetes. Oxidative stress occurs in a cellular system when the production of free radical moieties exceeds the antioxidant capacity of that system. If cellular antioxidants do not remove free radicals, radicals attack and damage proteins, lipids, and nucleic acids. The oxidized or nitrosylated products of free radical attack have decreased biological activity, leading to loss of energy metabolism, cell signaling, transport, and other major functions. These altered products are also targeted for proteosome degradation, further decreasing cellular function. Accumulation of such injury ultimately leads a cell to die through necrotic or apoptotic mechanisms. In conclusion, a puzzle of many pieces of evidence suggests that free radical overgeneration may be considered the key in the generation of insulin resistance, diabetes, and cardiovascular disease.

    Currently, the Friedewald formula (FF) is the main method for evaluating low-density lipoprotein cholesterol (LDL-c). Recently, many limitations have emerged regarding its use, including patients with triglyceride levels ≥400 mg/dL, diabetes mellitus, and kidney or hepatic chronic diseases. We analyzed the use of the FF in patients with metabolic syndrome. We selected patients with known metabolic syndrome that fulfilled the National Cholesterol Education Program Expert Panel on Detection, Evaluation and Treatment of High Blood Cholesterol in Adults (Adult Treatment Panel III) Final Report and excluded patients with triglyceride levels ≥400 mg/dL and chronic liver and/or kidney disease. Using direct assays, we measured total cholesterol, high-density lipoprotein cholesterol, triglycerides, and LDL-c. Then, LDL-c was estimated using the FF and compared with the LDL-c by direct assay. The sample size was 135 patients. Using the FF, the mean LDL-c value was 124.4 ± 42.1 mg/dL; it was 125.1 ± 38.5 mg/dL by direct assay. The correlation coefficient between these two methods was 0.89, with statistical significance (P  value < 0.001). There were no significant differences between the patients with triglyceride levels >150 mg/dL (P = 0.618). In conclusion, FF is a good method for estimating LDL-c in patients with metabolic syndrome. PMID:24672715

    Schizophrenia and other psychotic disorders are associated with high morbidity and mortality, due to inherent health factors, genetic factors, and factors related to psychopharmacological treatment. Antipsychotics, like other drugs, have side-effects that can substantially affect the physical health of patients, with substantive differences in the side-effect profile and in the patients in which these side-effects occur. To understand and identify these risk groups could help to prevent the occurrence of the undesired effects. A prospective study, with 24 months follow-up, was conducted in order to analyse the physical health of severe mental patients under maintenance treatment with atypical antipsychotics, as well as to determine any predictive parameters at anthropometric and/or analytical level for good/bad outcome of metabolic syndrome in these patients. There were no significant changes in the physical and biochemical parameters individually analysed throughout the different visits. The baseline abdominal circumference (lambda Wilks P=.013) and baseline HDL-cholesterol levels (lambda Wilks P=.000) were the parameters that seem to be more relevant above the rest of the metabolic syndrome constituents diagnosis criteria as predictors in the long-term. In the search for predictive factors of metabolic syndrome, HDL-cholesterol and abdominal circumference at the time of inclusion were selected, as such that the worst the baseline results were, the higher probability of long-term improvement.

  11. Utilization of dietary glucose in the metabolic syndrome

    PubMed Central

    2011-01-01

    This review is focused on the fate of dietary glucose under conditions of chronically high energy (largely fat) intake, evolving into the metabolic syndrome. We are adapted to carbohydrate-rich diets similar to those of our ancestors. Glucose is the main energy staple, but fats are our main energy reserves. Starvation drastically reduces glucose availability, forcing the body to shift to fatty acids as main energy substrate, sparing glucose and amino acids. We are not prepared for excess dietary energy, our main defenses being decreased food intake and increased energy expenditure, largely enhanced metabolic activity and thermogenesis. High lipid availability is a powerful factor decreasing glucose and amino acid oxidation. Present-day diets are often hyperenergetic, high on lipids, with abundant protein and limited amounts of starchy carbohydrates. Dietary lipids favor their metabolic processing, saving glucose, which additionally spares amino acids. The glucose excess elicits hyperinsulinemia, which may derive, in the end, into insulin resistance. The available systems of energy disposal could not cope with the excess of substrates, since they are geared for saving not for spendthrift, which results in an unbearable overload of the storage mechanisms. Adipose tissue is the last energy sink, it has to store the energy that cannot be used otherwise. However, adipose tissue growth also has limits, and the excess of energy induces inflammation, helped by the ineffective intervention of the immune system. However, even under this acute situation, the excess of glucose remains, favoring its final conversion to fat. The sum of inflammatory signals and deranged substrate handling induce most of the metabolic syndrome traits: insulin resistance, obesity, diabetes, liver steatosis, hyperlipidemia and their compounded combined effects. Thus, a maintained excess of energy in the diet may result in difficulties in the disposal of glucose, eliciting inflammation and the

Both study groups had a comparable and balanced nutrition with no specific dietary restrictions. Anthropometric, metabolic and cardiovascular parameters were measured 10-14 days before vacation, several times during the 3-week vacation, 7-10 days and 6-8 weeks after return. All participants tolerated the vacation without any adverse effects. Body weight, body fat, waist-circumference, fasting glucose, total cholesterol, LDL-cholesterol (LDL-C), plasma fibrinogen, resting systolic and diastolic blood pressure were significantly decreased over time in both study groups. In the LA group, fasting insulin and homeostasis model assessment (HOMA)-index were significantly decreased one week after return. Relative cycle ergometry performance was significantly increased after return compared to baseline. In both study groups, waist-to-hip ratio (WHR), 2-h oral glucose tolerance test (OGTT), HDL-cholesterol (HDL-C), and triglycerides remained unchanged. The 3-week vacation intervention at moderate and LA had a positive influence on all key-markers of the metabolic s
