Carotid Extra-Media Thickness in Children: Relationships With Cardiometabolic Risk Factors and Endothelial Function

Background: Emerging evidence suggests that structural adventitial modifications and perivascular adipose tissue (PAT) may have a role in early atherogenesis. In a cohort of children and adolescents, we explored (1) the association of carotid extra-media thickness (cEMT), an ultrasound measure whose main determinants are arterial adventitia and PAT, with obesity and its cardiometabolic complications; and (2) the interplay between cEMT and endothelial function.Methods: The study participants included 286 youths (age, 6–16 years; 154 boys, and 132 girls). Anthropometric and laboratory parameters, liver ultrasound, vascular structure measures [cEMT and carotid intima-media thickness (cIMT)], endothelial function [brachial artery flow-mediated dilation (FMD)] were obtained in all subjects. Non-alcoholic fatty liver disease (NAFLD) was diagnosed in the presence of hepatic fat on ultrasonography, in the absence of other causes of liver disease. Diagnosis of metabolic syndrome (MetS) was established on the basis of three or more of the following cardiovascular disease (CVD) risk variables: abdominal obesity, high triglycerides, low high-density lipoprotein cholesterol, elevated blood pressure (BP), and impaired fasting glucose.Results: cEMT demonstrated significant associations with body-mass index (BMI) and waist circumference (WC), BP, insulin resistance, NAFLD, and inflammation. No association was found between cEMT and lipid values, and between cEMT and MetS. A stepwise mu...

In conclusion, long-term feeding of either HFHF or WDHC are reliable methods to induce NASH and diet-potentiated liver cancer in mice of both sexes; however, the choice of diet involves a trade-off between severity of metabolic syndrome and liver damage.

Abstract BACKGROUND: Non-alcoholic fatty liver disease (NAFLD), in which abnormal lipid metabolism plays an important role in disease progression, has become a pandemic. Abnormal lipid metabolism, for example an increased fat intake, has been thought to be an initial factor leading to NAFLD. The small intestine is the main site of dietary lipid absorption. A number of clinical trials have shown that acupuncture has positive effects in the regulation of lipid metabolism, which is closely associated with the progression of NAFLD. We therefore hypothesized that, acupuncture can improve the conditions of NAFLD by regu...

This study was the first to demonstrate a causal relationship between glial senescence and neurodegeneration. In this study, accumulations of senescent astrocytes and microglia were found in tau-associated neurodegenerative disease model mice. Elimination of these senescent cells via a genetic approach can reduce tau deposition and prevent the degeneration of cortical and hippocampal neurons. Most recently, it was shown that clearance of senescent oligodendrocyte progenitor cells in AD model mice with senolytic agents could lessen the Aβ plaque load, reduce neuroinflammation, and ameliorate cognitive deficits. ...

Obesity and its immediate consequences, such as non-alcoholic fatty liver disease and type 2 diabetes, are associated with greater neuroinflammation and risk of dementia. Excess visceral fat tissue does its part to produce chronic inflammation throughout the body, but here researchers focus on a specific metabolic dysregulation in the liver that produces inflammation in the brain. That inflammation in turn drives a faster progression towards neurodegenerative conditions. The lesson here, as in so much of this research: don't get fat, don't stay fat. You won't like the consequences. Researchers have revealed the ca...

This study provides direct evidence for the contribution of gut microbiota to the cognitive decline during normal aging and suggests that restoring microbiota homeostasis in the elderly may improve cognitive function. On Nutraceutical Senolytics https://www.fightaging.org/archives/2020/05/on-nutraceutical-senolytics/ Nutraceuticals are compounds derived from foods, usually plants. In principle one can find useful therapies in the natural world, taking the approach of identifying interesting molecules and refining them to a greater potency than naturally occurs in order to produce a usefully large therape...

Non-alcoholic fatty liver disease is the most common cause of liver disease in the United States, and is estimated to affect up to a quarter of adults in the world. It is defined by excess fat accumulating in the liver and usually occurs in people with obesity, high blood sugars (diabetes), abnormal cholesterol or triglyceride levels, or high blood pressure. These disorders often run together and as a group are called metabolic syndrome. The “non-alcoholic” part of “non-alcoholic fatty liver disease” is important to distinguish it from alcohol-related liver disease, which can also cause excess liver...

Authors: Serradilla Martín M, Oliver Guillén JR, Palomares Cano A, Ramia Ángel JM Abstract The term "metabolic syndrome" refers to a group of alterations comprising central obesity reduced high-density lipoprotein cholesterol concentrations, elevated triglyceride concentrations, arterial hypertension, and hyperglycemia. This syndrome has established itself as one of the epidemics of the 21st century. Among its causative agents are insulin resistance, leptin and adiponectin, changes in microbiota, and epigenetics. Its incidence in the European population is estimated to be around 25%. ...
