BACKGROUND: Epicardial adipose tissues reflecting visceral fat accumulations of the heart are associated with metabolic syndrome (MetS) and can be a predictor of other cardiometabolic diseases. It can adversely influence autonomic nervous system (ANS) of heart. Heart rate recovery (HRR) is an easy method for measuring ANS dysfunction. The purpose of this study was to determine whether epicardial fat thickness (EFT) and nonalcoholic fatty liver disease (NAFLD) are related to HRR in patients with MetS...

Elevated circulating fatty acids (FAs) contribute to the development of obesity-associated metabolic complications such as insulin resistance (IR) and non-alcoholic fatty liver disease (NAFLD). Hence, reducing adipose tissue lipolysis to diminish the mobilization of FAs and lower their respective plasma concentrations represents a potential treatment strategy to counteract obesity-associated disorders. Here we show that specific inhibition of adipose triglyceride lipase (Atgl) with the chemical inhibitor, Atglistatin, effectively reduces adipose tissue lipolysis, weight gain, IR and NAFLD in mice fed a high-fat diet...

PURPOSE OF REVIEW: Cardiovascular disease (CVD) increasingly afflicts people living with HIV (PLWH) in the contemporary era of antiretroviral therapy (ART). Coronary artery disease (CAD) is the most widely studied cardiovascular problem in PLWH; however, less is known about other clinically relevant subtypes of CVD such as heart failure (HF), cerebrovascular disease, sudden cardiac death, pericardial diseases, and pulmonary hypertension. This paper reviews evidence of other subtypes of CVD as emerging issues in the post-ART era...

Ectopic adipose tissue surrounding the intra-abdominal organs (visceral fat) and located in the liver, heart, pancreas and muscle, is linked to cardio-metabolic complications commonly experienced in type 2 diabetes. A systematic review and meta-analysis was performed to determine the effect of exercise on ectopic fat in adults with type 2 diabetes. Relevant databases were searched to February 2016. Included were randomised controlled studies, which implemented≥4 weeks of aerobic and/or resistance exercise and quantified ectopic fat via magnetic resonance imaging, computed tomography, proton magnetic resonance spectroscopy or muscle biopsy before and after intervention...

In the last decades the prevalence of non-alcoholic fatty liver disease (NAFLD) has increased as a consequence of the childhood obesity world epidemic. The liver damage occurring in NAFLD ranges from simple steatosis to steatohepatitis, fibrosis and cirrhosis. Recent findings reported that fatty liver disease is related to early atherosclerosis and cardiac dysfunction even in the pediatric population. Moreover, some authors have shown an association between liver steatosis and cardiac abnormalities, including rise in left ventricular mass, systolic and diastolic dysfunction and epicardial adipose tissue thickness...

Chronic hepatitis C virus (HCV) is associated with insulin resistance (IR) and leads to type 2 diabetes mellitus (T2DM) and hepatic steatosis in many patients. These metabolic complications of HCV have been shown to accelerate the progression of fibrosis to cirrhosis and increase the risk of hepatocellular carcinoma. The metabolic syndrome is a common disorder that also includes IR, T2DM and hepatic steatosis. Approximately 20%-30% of patients with chronic HCV also have co-existent metabolic syndrome. The cause of steatosis in patients with the features of both the metabolic syndrome and chronic HCV is sometime difficult to determine...

BACKGROUND: A measure of donor liver quality, the donor liver index, was developed and validated for the UK population of transplant recipients. Unlike previously proposed measures, this index is only based on variables that are available at the point of retrieval, and so does not include cold ischemic time. METHODS: Indices of liver quality were based on data from the UK Transplant Registry on all 7929 liver transplants between January 2000 and December 2014. RESULTS: The donor liver index (DLI) was based on factors shown to affect graft survival, which included donor age, sex, height, type (donor after brain death or circulatory death), bilirubin, smoking history, and whether the liver was split...

BACKGROUND: The leading cause of death among the obese population is heart failure and stroke prompted by structural and functional changes in the heart. The molecular mechanisms that underlie obesity-related cardiac remodeling are complex, and include hemodynamic and metabolic alterations that ultimately affect the functionality of the myocardium. G protein-coupled receptor kinase 2 (GRK2) is an ubiquitous kinase able to desensitize the active form of several G protein-coupled receptors (GPCR) and is known to play an important role in cardiac GPCR modulation...

Several lines of evidence point to the association of vitamin D deficiency with the different components of metabolic syndrome. Yet, the effect of vitamin D supplementation on metabolic syndrome is not clearly elucidated. Herein, we tested the hypothesis that administration of vitamin D, either alone or in combination of metformin can improve metabolic and structural derangements associated with metabolic syndrome. Fifty wistar rats were randomly assigned to serve either as normal control (10 rats) or metabolic syndrome rats, by feeding them with a standard or a high fat diet (HFD), respectively...

BACKGROUND: Older liver grafts have been considered in the past decade due to organ shortage. The aim was to compare outcomes after liver transplantation with either younger or older donors. METHODS: Patients transplanted in our center between 2004 and 2014 with younger donors (younger than 60 years; n = 253) were compared with older donors (older than 75 years; n = 157). Multiorgan transplantations, split grafts, or non-heart-beating donors were not included. RESULTS: Donors in the older group were mostly women deceased from stroke, and only 3 patients had experienced cardiac arrest...

Mutations of the AMP-activated kinase gamma 2 subunit (AMPKγ2), N488I (AMPKγ2(NI)) and R531G (AMPKγ2(RG)), are associated with Wolff-Parkinson-White (WPW) syndrome, a cardiac disorder characterized by ventricular pre-excitation in humans. Cardiac-specific transgenic overexpression of human AMPKγ2(NI) or AMPKγ2(RG) leads to constitutive AMPK activation and the WPW phenotype in mice. However, overexpression of these mutant proteins also caused profound, non-physiological increase in cardiac glycogen, which might abnormally alter the true phenotype...

Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum of liver diseases from simple steatosis with hepatic lipid accumulation to end-stage liver disease with decompensated cirrhosis, liver failure and hepatocellular carcinoma. Recent data from the USA showed that in 2013, NAFLD was the second most frequent indication for liver transplantation behind hepatitis C. Since there are now effective treatments for hepatitis C and there is currently no licensed treatment for NAFLD, it has been predicted that over the next 10-15 years, NAFLD will replace hepatitis C as the most frequent indication for liver transplantation...

BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is the hepatic manifestation of metabolic syndrome and coronary artery disease (CAD) is the cardiac manifestation of metabolic syndrome. NAFLD is strongly linked to CAD and hepatic steatosis is an independent risk factor for CAD and cardiac mortality. The pathogenic mechanism underlying this association remains poorly understood. In this study, we explored expression of circulating microRNAs (miRNAs) in patients with NAFLD and associated CAD...

Cardiovascular (CV) disease is the most common cause of morbidity and mortality worldwide, particularly in the presence of the metabolic syndrome (MetS). Classifications and treatment of the MetS have recently been redefined. While the majority of the cardiac components such as hypertension, diabetes mellitus (DM) and dyslipidemia are objectively measurable elements, a few disparities among the definitions have to be considered that can variably modify diagnosis, treatment and prevention. Noncardiac factors such as liver disease (including, but not limited to, alcoholic and non-alcoholic steatosis/hepatitis), renal disease, severe obesity, polycystic ovarian syndrome and obstructive sleep apnea, may have independent or synergistic relationship with complementary cardiac MetS elements, and these additional risk factors may have an incremental adverse impact on CV outcome...

BACKGROUND: Type 2 diabetes (T2D) and obesity are associated with nonalcoholic fatty liver disease, cardiomyopathy, and cardiovascular mortality. Both show stronger links between ectopic and visceral fat deposition, and an increased cardiometabolic risk compared with subcutaneous fat. OBJECTIVES: This study investigated whether lean patients (Ln) with T2D exhibit increased ectopic and visceral fat deposition and whether these are linked to cardiac and hepatic changes...

The heart has a limited capacity for lipogenesis and de novo lipid synthesis. However, expression of lipogenic genes in cardiomyocytes is unexpectedly high. Recent studies showed that lipogenic genes are important factors regulating cardiac metabolism and function. Long chain fatty acids are a major source of ATP required for proper heart function, and under aerobic conditions, the heart derives 60-90% of the energy necessary for contractile function from fatty acid oxidation. On the other hand, cardiac lipid over-accumulation (e...

BACKGROUND: Coinfection with HIV/HCV is associated with more severe liver disease, including increased frequency of steatosis and significant fibrosis, compared to patients mono-infected with HCV or HIV. We sought to explore the impact of steatosis on cardiovascular disease (CVD), liver-related outcomes, and survival. METHODS: An IRB-approved, single-center retrospective cohort study was undertaken to analyze 10-year clinical outcomes in HIV/HCV-coinfected patients...

RATIONALE: Obesity is often associated with a state of oxidative stress and increased lipid deposition in the heart. More importantly, obesity increases lipid influx into the heart and induces excessive production of reactive oxygen species (ROS) leading to cell toxicity and metabolic dysfunction. Cluster differentiating 36 (CD36) protein is highly expressed in the heart and regulates lipid utilization but its role in obesity-associated oxidative stress is still not clear. OBJECTIVE: The aim of this study was to determine the impact of CD36 deficiency on cardiac steatosis, oxidative stress and lipotoxicity associated with obesity...

BACKGROUND AND AIMS: Obesity is often associated with an increased cardiovascular risk. The food industry and the associated research activities focus on formulating products that are a perfect mix between an adequate fat content and health. We evaluated whether a diet enriched with Bio-Oil Spread (SD), an olive oil-based innovative food, is cardioprotective in the presence of high-fat diet (HFD)-dependent obesity. METHODS AND RESULTS: Rats were fed for 16 weeks with normolipidic diet (ND; fat: 6...
