The aging effect on microvascular integrity, marked by endothelial dysfunction and reduction in exercise tolerance, is a major cause of CVD (cardiovascular disease). Improved dietary habits, known to reduce morbidity mortality, are also attenuate those effects. present study investigated the effects combined MD (Mediterranean diet) intervention lower- upper-limb cutaneous functions an older healthy population. A total 22 sedentary participants (age, 55±4 years) underwent cardiopulmonary...

Venous leg ulcers (VLUs) are typically painful and heal slowly. Compression therapy offers high healing rates; however, improvements not usually sustained. Exercise is a low-cost, low-risk effective strategy for improving physical mental health. Little known about the feasibility efficacy of supervised exercise training used in combination with compression patients VLUs.To assess 12-week programme as an adjunct to VLUs.This was two-centre, two-arm, parallel-group, randomized trial....

Smoking is a major risk factor for cardiovascular disease and smoking cessation reduces excess risk. E-cigarettes are popular but there little evidence on their health effect. Our objective was to compare the medium- longer-term effects in smokers attempting quit using e-cigarettes with or without nicotine prescription replacement therapy (NRT).

This study tested the potential risk-reduction benefits of Mediterranean Diet (MD) and regular exercise training on microvascular activity cardiorespiratory capacity in postmenopausal women. Fifteen sedentary participants (age = 54.6 ± 3.6) were randomised into either or combined with following MD for eight-weeks, assessed their capacity, upper- lower-limb endothelial cutaneous vascular conductance (CVC) test using Laser Doppler Fluximetry (LDF), coupled measuring endothelium-dependent...

Sleep is a vital element of adolescents’ overall health; it influences their body and mind thus affects quality life. Adequate sleep duration are essential for maintaining optimal metabolic health lowering the risk developing several medical conditions, such as cardiovascular disease. The current study aimed to assess perceived 1717 European adolescents from three different countries (Spain, Iceland Estonia) aged 13- 16-years (900 boys, 817 girls) using Pittsburgh Quality Index (PSQI).

The ability to increase skin blood flow (SkBF) rapidly in response local heating is diminished with advanced age; however, the mechanisms are unclear. primary aim of this study was investigate role sensory nerves age-related change. A secondary effect aerobic fitness on nerve-mediated vasodilatation young and aged skin. We measured SkBF (using laser Doppler flowmetry) older endurance-trained untrained men (n = 7 each group) at baseline during 35 min 42°C two sites ventral forearm. One site...

Sedentary aging results in a diminished rapid cutaneous vasodilator response to local heating. We investigated whether this was due altered contributions of noradrenergic sympathetic nerves by assessing 1) the age-related decline and 2) effect aerobic fitness. Using laser-Doppler flowmetry, we measured skin blood flow (SkBF) young (24 ± 1 yr) older (64 endurance-trained sedentary men (n = 7 per group) at baseline during 35 min heating 42°C untreated forearm sites, sites treated with...

Abstract Background Polycystic ovary syndrome (PCOS) affects up to 20% of women and is characterised by higher amounts visceral fat, obesity, insulin resistance, dyslipidemia reproductive cardiometabolic complications. Increased oxidised low-density lipoprotein (LDL) concentrations have been associated with an increased risk cardiovascular disease (CVD)-related events. Oxidised LDL rarely used as a marker for CVD in PCOS-related studies despite its widely accepted role atherogenesis the...
