Filter by:Non-communicable diseases (NCDs) are rising in prevalence because of aging, unhealthy diet and sedentary lifestyle, and common NCDs are caries and periodontitis (here oral diseases) and cardiovascular disease (CVD). Association between oral diseases and CVD has been observed in epidemiological studies, and suggested mechanisms include transfer of oral pathogen bacteria and pro-inflammatory mediators to other organs triggering immune response and systemic inflammation. Circulating mediators may initiate a response in the liver with production of C-reactive protein, serum amyloid A and increased tryptophan degradation, that contribute to CV inflammation and atherosclerosis. We have demonstrated that higher serum levels of these markers are associated with presence of hypertension and obesity and with higher risk of CVD. However, CVD and oral diseases also share many of the same risk factors, including hypertension, obesity, diabetes and smoking. Since the association of oral disease with CV risk factors mostly has been demonstrated in cross-sectional studies, the direction has not been ascertained. These CVD risk factors lead to changes in the heart and arteries (preclinical CVD); more harmful in women than men. If these conditions can impact development of oral diseases is not been investigated in large studies. Socio-economic inequalities have been reported for oral diseases and are linked to low socio-economic status (SES). It is unknown whether CV health and SES in midlife may impact prevalence of oral diseases later in life. It is also unknown if the oral microbiome differ by periodontitis severity and can be associated with inflammatory biomarkers, CV risk factors and preclinical CVD. The project will be performed in adults approaching the retirement age in Vestland county. We will combine their data from the ongoing Hordaland Oral Health Survey with their data from three surveys in the longitudinal Hordaland Health Study performed in the period 1992-2020.
Smoking is the "leading, preventable death-cause worldwide", being responsible for almost 700,000 deaths in the E.U. annually. Therefore, implementing successful, long-term smoking cessation strategies is a long-term priority for the NHS. Recent evidence suggests that e-cigarettes (i.e., vaping) are a successful cessation tool, with around 3.6 million users in the UK. There are concerns about long-term vaping, particularly in relation to their cardiovascular effects, as there are no relevant, longitudinal studies. Therefore, we propose a 38-month, four-group longitudinal study exploring the cardiovascular physiological effects of the use of e-cigarettes over a two-year period, informing policy makers and e-cigarette users (vapers). Our study was developed with the support of vapers. The main research question is whether there are any differences in cardiovascular physiology between vapers, who are ex-smokers (Group A), vapers with no previous smoking experience (Group B), dual users (i.e., those who vape and smoke (Group C) and ex-smokers who don't vape (Group D). Two-hundred participants from Sheffield and Leeds will be invited on five occasions (baseline, as well as 6-,12-,18- and 24-months post-baseline). We will assess macrovascular and lung function, cardiovascular disease risk (through questionnaires and blood biomarkers), vaping and smoking dependence, smoking and and vaping history among others.
The purpose of this survey is to collect information for scientific research and to better understand the role of systemic inflammation in identification, treatment and management of patients with ASCVD and CKD. This study is a cross-sectional design conducted among cardiologists in United Kingdom, Italy, Germany, Brazil, Saudi Arabia, Japan, Australia, China, India and France, treating ASCVD and CKD patients. Study participants will be recruited to complete an approximately 20-minute self-administered online survey. Recruitment will be conducted through email and phone. Data is collected though online data collection using a programmed survey.
An immediate perioperative parameter that assess the integrity of the Erythrocytes Membrane and therefore their structural quality isn't available in clinical practice and medical diagnostics except through indirect clinical biochemical tests or through the scanning electron microscope. The red blood cell (RBC) membrane contains proteins and glycoproteins embedded in a fluid lipid bilayer that confers viscoelastic behavior. Sialylated glycoproteins of the RBC membrane are responsible for a negatively charged surface which creates a repulsive electric zeta potential (ΞΆ) between cells. These charges help prevent the interaction between RBCs and the other cells and especially between each other. The zeta potential is a physical property which is exhibited by all particles in suspension. The development of a net charge on any particle affects the distribution of ions in the surrounding interfacial region resulting in an increased concentration of counter ions of opposite charge to that of the particle, close to the surface. In this context we present a new parameter that studies the interactions of the Erythrocytes membrane treated with positive ions and their maintenance of the charge. We compared the measured polarization values with the Erythrocyte Sedimentation Rate (ESR), expression of speed with which RBCs tend to settle inside a particular graduated capillary called Westergren's tube and Plasma Free Hemoglobin (pFHb).
This is an observational study aimed at exploring the relationship between psychological status and self-care in patients with chronic cardiovascular disease
This multicenter, double-blinded, randomized controlled trial aims to evaluate the effect of berberine on preventing cardiovascular disease and diabetes mellitus among individuals with high cardiometabolic risk in China.
The purpose of this study is to learn if there are predictive markers of hospitalization or death that can be found from data gathered from a Sleep Number® bed. This is a prospective observational cohort study that will follow participating subjects in the Masonic Homes/Acacia Creek Retirement Community in Union City, California.
Acute and chronic cardiovascular complications of pneumonia are common and result from various mechanisms, including relative ischemia, systemic inflammation, and pathogen-mediated injury. However, there is only limited published data regarding on cardiovascular desease (CV) submissions in the wake of viral outbreaks. Data collected during the COVID-19 pandemic highlighted a number of possible determinants of adverse outcome in these patients, particularly with reference to cardio-respiratory complications.
The aim of this randomised control trial is to investigate the role of fasted exercise on cardiometabolic health. Participants will be assigned to one of three conditions, fasted exercise, fed exercise and control (no exercise). Participants in the exercise groups will complete four weeks of moderate intensity cycling exercise, three times per week, either in the fasted or fed state according to their group assignment. Experimental trials involving anthropometric and cardiometabolic disease risk factor measurements as well as metabolic responses to a subsequent meal ingestion following exercise will be compared pre-intervention and post intervention.
The goal of this single-center prospective randomized controlled parallel 2-arm intervention study is to test a lifestyle intervention focusing on diet and physical activity in students and at least one legal guardian to improve cardiovascular risk factor profiles. The primary objective of this study ist to evaluate the efficacy of a health promotion intervention (intervention group) over the course of a year using a participative approach compared to a control group in 14- to 17-year-olds and at least one legal guardian. Further study objectives are to determine the effect of the health promotion intervention on the change of the score of the individual health metric components, on the absolute health metric score, on the change in intima-media thickness and pulse-wave velocity and cardiovascular health (such as blood pressure, non-HDL-cholesterol, BMI) as well as health literacy with regards to CVDs, especially stroke, in both age-groups. Furthermore, a biobank will be collected.
