The mammalian target of rapamycin (mTOR) is a regulator of metabolism and is implicated in pathological conditions such as obesity and diabetes. We aimed to investigate the role of mTOR in obesity. A new animal model of metabolic syndrome (MetS), named DahlS.Z-Lepr(fa) /Lepr(fa) (DS/obese) rats was established previously in our laboratory. In this study, we used this model to evaluate the effects of mTOR inhibition on cardiac and adipose tissue pathology and glucose metabolism. DS/obese rats were treated with the mTOR inhibitor, everolimus, (0...

Atypical antipsychotics such as olanzapine often induce excessive weight gain and type 2 diabetes. However, the mechanisms underlying these drug-induced metabolic perturbations remain poorly understood. Here, we used an experimental model that reproduces olanzapine-induced hyperphagia and obesity in female C57BL/6 mice. We found that olanzapine treatment acutely increased food intake, impaired glucose tolerance, and altered physical activity and energy expenditure in mice. Furthermore, olanzapine-induced hyperphagia and weight gain were blunted in mice lacking the serotonin 2C receptor (HTR2C)...

Morbid obesity is a barrier to KT due to inferior outcomes, including higher rates of new-onset diabetes after transplantation (NODAT), delayed graft function (DGF), and graft failure. LSG increases transplant eligibility by reducing body mass index (BMI) in KT candidates, but the effect of surgical weight loss on post-transplant outcomes is unknown. Reviewing single-center medical records, we identified all patients who underwent LSG prior to KT from 2011-2016 (n=20). Post-LSG kidney recipients were compared with similar-BMI recipients who did not undergo LSG, using 2:1 direct matching for patient factors...

BACKGROUND: In March, 2016, the UK Government proposed a tiered levy on sugar-sweetened beverages (SSBs; high tax for drinks with >8 g of sugar per 100 mL, moderate tax for 5-8 g, and no tax for <5 g). We estimate the effect of possible industry responses to the levy on obesity, diabetes, and dental caries. METHODS: We modelled three possible industry responses: reformulation to reduce sugar concentration, an increase of product price, and a change of the market share of high-sugar, mid-sugar, and low-sugar drinks...

Activated cell surface and intracellular receptors lead to insulin resistance in obesity. Among these receptors, triggering receptors expressed on myeloid cells (TREM)-1, toll like receptors (TLRs), and receptors for advanced glycation end products (RAGE) play a significant role in the induction of inflammatory response in innate immunity. TREM-1 potentially amplifies TLRs and RAGE synergistically with DNA-binding high-mobility group box 1 (HMGB-1). The objective of the study was to analyze the association between TREM-1/DAP12 and HMGB-1, RAGE and TLRs in obesity-induced insulin resistance...

Recent findings point toward diet having a major impact on human health. Diets can either affect the gut microbiota resulting in alterations in the host's physiological responses or by directly targeting the host response. The microbial community in the mammalian gut is a complex and dynamic system crucial for the development and maturation of both systemic and mucosal immune responses. Therefore, the complex interaction between available nutrients, the microbiota, and the immune system are central regulators in maintaining homeostasis and fighting against invading pathogens at mucosal sites...

Hypertension (HT) is a systemic disorder that results in the decline of quality of life and death. While patients with periodontitis are at a high risk of HT, little causal information has been provided to date. To clarify the relationship, periodontopathic bacterial infection in cardiovascular patients with or without HT was evaluated. The subjects were patients with (n = 412) or without (n = 199) HT who attended Tokyo Medical and Dental University hospital. Blood examinations and periodontal measurements were performed...

PURPOSE: Bariatric surgery (BS) promotes carotid intima-media thickness (C-IMT) regression as early as 6 months post-surgery. To verify whether C-IMT regression occurs even earlier, we aimed at the effect of Roux-en-Y gastric bypass (RYGBP) and biliopancreatic diversion (BPD) on C-IMT 1-2 months and 12 months post-surgery. SUBJECTS/METHODS: Prospective trial. BS was performed on 109 patients either with (RYGBP = 42; BDP = 40) or without type 2 diabetes (RYGBP = 27)...

BACKGROUND: The complications associated with obesity have been well described for posterior lumbar spinal surgery. However, the influence of obesity on anterior lumbar interbody fusion (ALIF) is not well established. We aimed to compare complication risks, functional outcomes and subsidence rates in normal, overweight and obese patients who underwent ALIF. METHODS: 137 consecutive patients undergoing ALIF surgery from 2012-2014 were prospectively followed. Patients were categorized into 3 groups according to their body mass index (BMI)...

BACKGROUND: Regular engagement in physical activity can help youth control their weight during childhood while decreasing one's chances of developing chronic diseases (e.g., coronary heart disease, diabetes) throughout the lifespan. While numerous studies have explored physical activity participation and weight status among typically developing children, few epidemiological studies utilizing nationally representative data has focused on children with chronic health problems, illness, or disabilities (CHID)...

Gut hormones have long been understood to regulate food intake and metabolism. Bariatric surgery significantly elevates circulating gut hormone levels and is proven to affect acute remission of type 2 diabetes before any weight loss is observed. Subsequent weight loss is accrued over weeks to months but is sustained into the long term. Hence, there exists great enthusiasm to recapitulate these changes in gut hormones in the form of novel combination drugs for type 2 diabetes and obesity.

BACKGROUND & AIMS: Cardiovascular disease (CVD) is the leading cause of death among patients with non-alcoholic fatty liver disease (NAFLD). Moderate drinking (vs abstinence) is associated with lower risk of CVD in the general population. We assessed whether alcohol use is associated with CVD risk in patients with NAFLD. METHODS: We analyzed data from participants in the Coronary Artery Risk Development in Young Adults longitudinal cohort study of 5115 black and white young adults, 18-30 years old, recruited from 4 cities in the United States from 1985 through 1986...

BACKGROUND AND OBJECTIVES: Findings from observational studies in China show that increased dietary fat consumption might be a contributor to the developing obesity epidemic. However, some cohort studies suggest that carbohydrate intake, especially from white rice, is a risk factor for obesity, type 2 diabetes and coronary heart disease in China. Our study aims to determine whether the traditional lower-fat, higher-carbohydrate Chinese or the Western higher-fat, lower-carbohydrate dietary pattern is more effective for weight control and the related cardiometabolic profiles increasingly found among contemporary Chinese...

A low-protein diet (LPD), particularly, very low-protein diet (VLPD) is expected for reno-protection in advanced chronic kidney disease, including diabetic nephropathy. We previously also demonstrated that a VLPD clearly improved advanced diabetic nephropathy in a type 2 diabetes and obesity rat. However, clinically, an everyday long-term VLPD contributes to poor adherence, which may be related to controvertial results of an LPD on the suppression for diabetic nephropathy, and has nutritional issues, such as sarcopenia or protein-energy wasting...

Plasma concentrations of amino acids (AA), in particular branched chain (BCAA), are often found increased in non-alcoholic fatty liver disease (NAFLD). However, if this is due to increased muscular protein catabolism, obesity and/or increased insulin resistance (IR) or impaired tissue metabolism is not known. Thus, we evaluated a) if subjects with NAFLD non-obese (NAFLD-NO), compared to obese (NAFLD-Ob) display altered plasma AA compared to controls (CT); b) if AA concentrations are associated to IR and liver histology...

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) and resulting nonalcoholic steatohepatitis (NASH) are highly prevalent in the US, where they are a growing cause of cirrhosis and hepatocellular carcinoma (HCC), and increasingly, an indicator for liver transplantation. METHODS: A Markov model was used to forecast NAFLD disease progression. Incidence of NAFLD was based on historical and projected changes in adult prevalence of obesity and type 2 diabetes mellitus (DM)...

Exercise training is a potent, therapeutic approach in obesity and diabetes that exerts protective effects against development of diabetic cardiomyopathy and ischemic-injury. Acute increases in circulating fatty acids (FAs) during an ischemic insult can challenge the heart, as high FA-load is considered to have adverse cardiac effects. In the present study, we tested the hypothesis that exercise-induced cardiac effects in diet-induced obese mice are abrogated by an acute high FA-load. Diet-induced obese mice were fed a high-fat diet (HFD) for 20 weeks...

Salsalate plays beneficial roles for ameliorating hyperglycemia and dyslipidemia in type 2 diabetes patients, but the underlying mechanisms are still poorly understood. In this study, by administering salsalate to mice fed with high fat diet and examining how salsalate rectifies metabolic dysfunction in these obese mice, we found that salsalate stimulated body temperature and attenuated body weight gain without affecting food intake. Our results showed that salsalate application decreased lipid accumulation in liver and epididymal white adipose tissue (eWAT), inhibited hepatic gluconeogenesis and improved insulin signaling transduction in eWAT...
