Natriuretic Peptides (NP) are hormones produced by the heart, and they have a wide range of favorable metabolic benefits. Lower levels of these hormones are associated with an increased likelihood of the development of diabetes and poor cardiometabolic health. Obese and Black individuals have ~30% lower levels of NP and are at a greater risk of developing cardiovascular (CV) events as compared to lean and White counterparts. Some people have common genetic variations that cause them to have ~20% lower NP levels. Similar to other low NP populations, these individuals with low NP genotype (i.e., carrying a common genetic variation called rs5068) are at a greater risk of developing cardiometabolic diseases. By understanding the NP response following the exercise challenge and the glucose challenge in individuals with genetically lower NP levels will help us understand how to improve cardiometabolic health in them.
The purpose of this study is to improve the cardiovascular care of adult cancer survivors. The goal is to obtain the data necessary to plan and develop a nation-wide network of a screening program that can help provide cost-effective and long-term monitoring.
The investigators are planning to find the right modification of traditionally used risk scores (PASI, DLQI) in patients with psoriasis of different severity to guide the treatment that could potentially extend life, improve cardiovascular outcomes and quality of life in patients with psoriasis and cardiovascular risk factors in a prospective observational study. The traditionally excluded groups of older patients with diabetes mellitus, decreased kidney function and those with potentially worse prognosis are going to be included in the study. As it's known, the number of those patients is on the rise each year and require a close attention of multidisciplinary teams.
The development of type II diabetes (T2D) is strongly associated with obesity and both are well-established risk factors for cardiovascular disease. Knowing that vascular dysfunction is an early event in the development of cardiovascular disease in obese diabetic (OB-T2D) patients, The investigators set their long-term goal to define molecular mechanisms of vascular dysfunction and corrective strategies that target these mechanisms such as physical activity and weight loss. The investigators recently discovered that human adipose tissues release extracellular vesicles (adiposomes) that are efficiently captured by endothelial cells. Adiposomes are known to carry bioactive cargos such as proteins and micro RNAs; however, their lipid content has not been studied nor has their ability to transfer their lipid cargo to endothelial cells. In the current application, the investigators propose to investigate the role of adiposomes in communicating the unhealthy milieu, mainly dysregulated lipids, to endothelial cells in OB-T2D subjects. On top of these lipid species that the investigators propose to be carried by adiposomes are glycosphingolipids (GSLs). These lipids originate from the glycosylation of ceramides, a chemical process that is upregulated in the presence of inflammation and high glucose levels. Preliminary findings showed that in endothelial cells, GSL-rich adiposomes disturb plasma membrane structure and subsequently induce endothelial dysfunction. Moreover, the investigators found that preconditioning endothelial cells with high shear stress (which is an exercise mimetic) protected endothelial cells from the detrimental effects induced by adiposomes. Therefore, the central hypothesis is that adipose tissues in OB-T2D patients release GSL-loaded adiposomes that induce vascular endothelial dysfunction. The researchers propose that exercise and weight loss interventions (bariatric surgery) will restore adipose tissue homeostasis, reduce GSL-loaded adiposomes, and subsequently alleviate vascular risk in OB-T2D patients. The investigators will test the hypotheses by pursuing the following aims: aim 1: Investigate the role of GSL-rich adiposomes in the pathogenesis of endothelial dysfunction in OB-T2D adults; aim 2: Test the effectiveness of exercise training in reducing adiposome-mediated effects on vascular function; and aim 3: Examine changes in adiposome/caveolae axis following metabolic surgery and their association with vascular function.
The National Registry of Cardiovascular Surgery in Argentina is a registry of patients undergoing cardiovascular surgery that involves the entire country with the ultimate aim of determining the results of said surgery throughout the country.
The purpose of this single-arm interventional study is to evaluate the long-term safety, efficacy, and durability of the Symplicity Spyral system in subjects treated with renal denervation. Additionally, long-term follow-up data will also be collected from eligible subjects previously treated in the SPYRAL PIVOTAL-SPYRAL HTN-OFF MED and SPYRAL HTN-ON MED studies.
Cardiovascular Disease (CVD) is one of the greatest causes of mortality and morbidity globally, particularly in middle to high income countries. In the UK alone, it was accountable for 124,641 deaths in 2017. Further to this, CVD contributes to a vast economic burden, costing the National Health Service (NHS) £19billion annually. This is mainly due to a significant number of hospital readmissions following a first cardiac event (198,000 per annum). Following a cardiac event, an individual is therefore recommended to reduce their risk factors, including lipid profile, smoking status and physical inactivity, to reduce their risk of a secondary event. In healthy individuals, regularly breaking up sitting time reduces cardiometabolic risk markers. The aim of this study is to therefore observe if this effect is replicated in the cardiac population and thus whether breaking up sitting time will reduce the risk of a secondary cardiac event. Potential participants will be required to meet an inclusion criteria to take part in the study: aged 50 years or above and had a myocardial infarction within the past three months at the time of recruitment to the study. Participants will be randomised to each condition: 1) uninterrupted sitting; 2) sitting with intermittent standing and 3) sitting with intermittent light physical activity (stepping to a metronome beat). A number of physiological markers will be measured before, during and after each condition and analysed to compare the effectiveness of each condition. All measurements will be taken at the University of Bedfordshire Sport and Exercise Science Laboratories.
This study is a mechanistic clinical trial designed to investigate the effects of the circadian system and sleep on non-dipping blood pressure (BP) in people with hypertension (HTN).
The purpose of this study is to assess the effectiveness and the safety of extracorporeal methods for removing mediators of systemic inflammation in patients with multiple organ dysfunction syndrome after heart and aorta surgery.
