AIMS/HYPOTHESES: Reduced mitochondrial capacity in skeletal muscle has been observed in obesity and type 2 diabetes. In humans, the aetiology of this abnormality is not well understood but the possibility that it is secondary to the stress of nutrient overload has been suggested. To test this hypothesis, we examined whether sustained overfeeding decreases skeletal muscle mitochondrial content or impairs function. METHODS: Twenty-six healthy volunteers (21 men, 5 women, age 25...

Cholesterol is a key component of the cell plasma membrane. It has been suggested that the t-tubule membrane of cardiac ventricular myocytes is enriched in cholesterol and that this plays a role in determining t-tubule structure and function. We have used methyl-β-cyclodextrin (MβCD) to deplete cholesterol in intact and detubulated mouse ventricular myocytes to investigate the contribution of cholesterol to t-tubule structure, membrane capacitance, and the distribution of Ca flux pathways. Depletion of membrane cholesterol was confirmed using filipin; however, di-8-ANEPPS staining showed no differences in t-tubule structure following MβCD treatment...

BACKGROUND: A low level of high-density lipoprotein cholesterol (HDL-C) is a common clinical scenario and poses challenges for management. Many patients with low HDL-C harbor a damaging mutation in ABCA1 or APOA1, but the clinical implications of genetic testing for these mutations are unclear. OBJECTIVE: The purpose of this study was to investigate the prevalence of clinical or subclinical atherosclerosis among patients with low HDL-C due to a mutation in ABCA1 or APOA1, compared with patients with low HDL-C without such a mutation...

PURPOSE: The objective of this study was to evaluate the efficacy and tolerability of a triple combination of amlodipine/losartan/rosuvastatin in patients with hypertension and hypercholesterolemia. METHODS: A randomized, multicenter, double-blind, placebo-controlled study was conducted. Eligible patients with hypertension and a sitting diastolic blood pressure (SiDBP) of >90 mm Hg and LDL-C levels <250mg/dL were screened. After a 4-week run-in period with therapeutic lifestyle changes and losartan potassium 100mg once daily, patients who met both blood pressure criteria (80 mm Hg ≤ SiDBP < 110 mm Hg) and the LDL-C level criteria (defined in the National Cholesterol Education Program Adult Treatment Panel III cardiovascular risk categories) were randomized to 1 of 3 groups and treated once daily for 8 weeks: losartan potassium 100mg + rosuvastatin 20mg treatment (L/R 100/20) group, amlodipine camsylate 5mg + losartan potassium 100mg treatment (A/L 5/100) group, and amlodipine 5mg+ losartan potassium 100mg + rosuvastatin 20mg (A/L/R 5/100/20) group...

BACKGROUND: Sirtuins, including SIRT1 and SIRT2, are longevity-associated deacetylase enzymes that modulate metabolic homeostasis in response to the cellular energy state. Adenosine monophosphate activated protein kinase (AMPK) and SIRT1 are interrelated and share several common target pathways. This study aimed to evaluate the SIRT1 and SIRT2 gene expression in peripheral blood mononuclear cells (PBMCs) as well as plasma levels of AMPK, in obese children and adolescents. MATERIALS AND METHODS: Participants included 60 children and adolescents (30 obese and 30 age- and gender-matched control subjects)...

BACKGROUND: 18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016...

OBJECTIVE: Women are at increased risk of developing cardiovascular disease (CVD) after preeclampsia. Proneurotensin 1-117 (pro-NT) and prorelaxin 2 connecting peptide (pro-RLX2) have recently emerged as potential biomarkers for CVD risk in women. We assessed pro-NT and pro-RLX2 levels in women with and without a history of preeclampsia. STUDY DESIGN: 339 women with a history of early-onset preeclampsia and 327 women with an uncomplicated pregnancy underwent cardiovascular screening 10 years after delivery (the Preeclampsia Risk EValuation in FEMales (PREVFEM) cohort)...

Although high density lipoprotein cholesterol (HDL-C) levels are inversely proportional to cardiovascular risk in many studies, recent pharmacological interventional studies with HDL-C raising strategies did not show a benefit in terms of vascular events. The HDL particle is heterogenous with anti-atherogenic functions and non-vascular effects. Many factors affect HDL components and may either cause compositional changes, post-translational modifications of proteins, or alter lipids and other cargo molecules; generally these factors cause more than one of these changes, resulting in functional differences...

Dyslipidaemia occurs in pregnancy to secure foetal development. The mother shows a physiological increase in plasma total cholesterol and triglycerides (TG) as pregnancy progresses (i.e. maternal physiological dyslipidaemia in pregnancy). However, in some women pregnancy-associated dyslipidaemia exceeds this physiological adaptation. The consequences of this condition on the developing foetus include endothelial dysfunction of the foetoplacental vasculature and development of foetal aortic atherosclerosis. Gestational diabetes mellitus (GDM) associates with abnormal function of the foetoplacental vasculature due to foetal hyperglycaemia and hyperinsulinaemia, and associates with development of cardiovascular disease in adulthood...

Chrononutrition is the science of nutrition based on chronobiology. Numerous epidemiological studies have shown that fish oil (FO) reduces the risk of cardiovascular events through various actions such as lowering triglycerides. The present study aimed to determine the time of day when the hypertriglyceridemia-decreasing ability of FO is optimal in mice. A high-fructose diet (HFrD) that induces hyperlipidemia in mice was replaced with the same diet containing 4% FO (HFrD-4% FO) at different times of the day for 2 weeks as described below...

Cholesterol is a critical nutrient requiring tight constraint in the endoplasmic reticulum (ER) due to its uniquely challenging biophysical properties. While the mechanisms by which the ER defends against cholesterol insufficiency are well described, it remains unclear how the ER senses and effectively defends against cholesterol excess. Here, we identify the ER-bound transcription factor nuclear factor erythroid 2 related factor-1, Nrf1/Nfe2L1, as a critical mediator of this process. We show that Nrf1 directly binds to and specifically senses cholesterol in the ER through a defined domain and that cholesterol regulates Nrf1 turnover, processing, localization, and activity...

BACKGROUND: Elevated cholesterol has been linked to cardiovascular disease in adults and preclinical markers of atherosclerosis in children, thus reducing saturated (SFA) and trans-fatty acids (TFA) intake from an early age may help to reduce cholesterol and the risk of cardiovascular disease later in life. The aim of this review is to examine the evidence for health effects associated with reducing SFA and TFA intake in free-living children, adolescents and young adults between 2 to 19 years of age...

BACKGROUND: Mild obstructive sleep apnea (OSA) is a highly prevalent disorder in adults. However, it is not clear whether mild OSA has significant metabolic complications. This study examined the prevalence of metabolic syndrome (MS) in patients with mild OSA compared to control group. METHODS: Adults (18-65 years of age) of both genders with a body mass index (BMI) ≤35 kg/m(2) were included. The mild OSA group comprised of patients with an apnea-hypopnea index (AHI) score of ≥5 but ≤15 events/hr of sleep, independent of other symptoms...

With the advent of a new drug class - the proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors, patients have another treatment option for lowering their high levels of low-density lipoprotein cholesterol (LDL-C) in recent years. The objective of this study was to systematically review the cost-effectiveness of lipid-lowering agents such as statins, ezetimibe, and PCSK9 inhibitors. Areas covered: Based on PubMed, Embase, and Cochrane Database of Systematic Reviews, we identified a total of 29 relevant articles...

Ganglioside-enriched microdomains in the presynaptic neuronal membrane play a key role in the initiation of amyloid ß-protein (Aß) assembly related to Alzheimer's disease. We previously isolated lipids from a detergent-resistant membrane microdomain fraction of synaptosomes prepared from aged mouse brain and found that spherical Aß assemblies were formed on Aß-sensitive ganglioside nanoclusters (ASIGN) of reconstituted lipid bilayers in the synaptosomal fraction. In the present study, we investigated the role of oligosaccharides in Aß fibril formation induced by ganglioside-containing mixed lipid membranes that mimic the features of ASIGN...

While financial incentives to providers or patients are increasingly common as a quality improvement strategy, their impact on patient subgroups and health care disparities is unclear. To examine these patterns, we analyzed data from a randomized clinical trial of financial incentives to lower low-density lipoprotein (LDL) cholesterol levels in patients at risk for cardiovascular disease. Patients with higher baseline LDL experienced greater cholesterol reductions in the shared incentive arm (0.23 mg/dL per unit change in baseline LDL, 95% CI [-0...

BACKGROUND: A decrease in serum low-density lipoprotein cholesterol (LDL-C) is well documented after acute stress. Plasma proprotein convertase subtilisin kexin 9 (PCSK9), which promotes degradation of low-density lipoprotein receptor (LDL-R) resulting in reduced plasma clearance of low-density lipoproteins (LDL) and an increase in serum LDL-C, would be predicted to decrease. Yet, a few studies have demonstrated an increase 1-8 days after acute stress. Our objective was to assess the earlier status of plasma PCSK9, within the first 24 hours of onset of stress...
