Filter by:The main objective of this study is to compare the effect of 6 sessions of shock wave therapy versus radiofrequency followed by a protocol of moderate aerobic exercise, in the reduction of adiposity and abdominal flaccidity, in females between 18 and 60 years old. As a secondary objective, it is intended to understand the mechanism of fat mobilization by these two therapies.
Barriers to physical activity (PA) among African Americans (AAs) have been extensively studied, yet there is a paucity of innovative PA interventions designed to address them. In recent years, many studies have used the internet to promote PA in many settings, including the home environment, but only a few studies have recruited AAs. Without innovative and culturally relevant interventions, AAs will continue reporting extremely low levels of PA and disparate cardiovascular health outcomes. In prior work, the investigators sought the input of AA focus groups to inform the development of a technology-based Physical Activity for The Heart (PATH) intervention that leverages openly accessible platforms, such as YouTube, to promote PA in any setting. The investigators designed PATH as a culturally salient action-oriented intervention that can be accessed in any setting to promote PA among inactive AAs. In this application, the investigators propose to examine whether PATH is a feasible strategy for promoting PA among inactive AAs. In Aim 1 the investigators will conduct a randomized clinical trial that will include 30 inactive AAs to assess the feasibility and acceptability of the PATH intervention. In Aim 2 the investigators will examine the trend in PA and cardiovascular disease risk change from baseline to post-intervention. This approach is innovative because it leverages openly accessible technologies to provide a wide variety of free, enjoyable and action-oriented workout videos that match AAs preferences. This contribution will be significant because PATH could offer a novel, low-cost, and scalable strategy for promoting PA among individuals facing socio-environmental barriers to PA.
Background Cardiovascular disease is the leading cause of death in the U.S., however scientists have failed to learn fully what are the causes of this disease. A promising lead in understanding the origins of cardiovascular disease may be in gene expression changes occurring in utero in response to environmental (non-genetic) factors. Such changes govern whether a gene is turned on or turned off during an individual's lifetime. Twin pregnancies and twin infants help researchers to have a better understanding of whether the gene expression changes are genetic or environmental in origin. Therefore, the purpose of this project is to examine which body tissues (such as hair, fingernails, urine or blood) are needed to accurately study how gene activity is affected by prenatal factors.
This study is a blinded randomized crossover efficacy trial (N=172 households consisting of 207 participants) of High Efficiency Particulate Air (HEPA) filtration in near-highway homes that lack mechanical air-handling systems. Households will be randomized to 30 days of either filtration or sham filtration followed by a 30 washout period with a subsequent 30-day period of the alternative assignment. Room air filters that are commercially available will be placed in the bedroom and living room of each home. The investigators will measure UFP and PM2.5 concentrations in 20% of the homes during filtration and sham periods and assess personal exposure in a subset of participants. The investigators will also assess chemical composition of particulate air pollution in 10 homes/year for exploratory purposes that could lead to future lines of research. The primary health endpoints will be participants' hsCRP and peripheral blood pressure, measures that the investigators have used in multiple observational studies of UFP as well as in pilot filtration intervention studies. Secondary biological measures that contribute to understanding biological pathways will be IL-6 (inflammation), D-dimer (coagulation), metabolome, central pressure and arterial stiffness. The primary intention to treat analysis will compare outcomes between HEPA filtration to sham filtration. The investigators will have 80% power to detect a difference of 0.6 mg/L in change in hsCRP and a difference in reduction in systolic blood pressure of 3.5 mmHg compared to participants who receive no filtration. Having participants serve as their own controls in the within-subject comparisons of intervention effectiveness increases statistical power and eliminates the possibility of baseline imbalances in demographic and clinical characteristics. A social science evaluation will inform final adjustments to the investigators' approach at the start and also assess participant acceptance and experience with the intervention at the end. The investigators' primary innovation is that this will be the first near highway HEPA intervention trial that is large enough and careful enough to be policy-relevant.
The main objective is to determine the effectiveness of a program which consists of multidisciplinary, intensive and individualized interventions, carried out by a group of health professionals (psychiatrist, psychologist, mental health nurse, primary care doctors, pharmacist), during six-month, to improve the global cardiovascular risk (CVR) in patients with schizophrenia. Secondarily, will be analyzed the effectiveness of this program on improving the control in four selected cardiovascular risk factors: hypertension, hypercholesterolemia, hyperglycaemia and smoking, after 6 months Methods: randomized study with parallel assignment in two groups: control and intervention group, six-month follow-up. The eligible patients will be 130 adult (≥18 years) outpatients with a current diagnosis of schizophrenia who follow-up by health mental network in Catalonia, who presents at least bad control in one of the four selected cardiovascular risk factors. The intervention group will receive a multidisciplinary and individualized approach (psychoeducational, recommendations of life style and diet, medication adherence and changes in pharmacological strategy, depending on the individual needs assessing after cardiovascular risk screening. The control group will follow the standard management according to the primary care professionals' team. Main measurements: the global CVR at baseline and at six-month follow-up through Framingham tables calibrated for the Catalan population (Registre Gironí del Cor, REGICOR). Secondary measures: they will be determined, at baseline and at six-month follow-up, four cardiovascular risk factors as well: hypertension, hypercholesterolemia, hyperglycaemia and smoking, according with the latest recommendations of the Program of preventive activities and health promotion (PAPPS) of the Spanish Society of Family and Community Medicine. Other measures: anthropometric parameters. Functional Assessment Screening Tool (FAST) and quality of life (EQ-5D).
This study aims to elucidate the impact of SGLT2 inhibition on peripheral vascular function, renal function, fluid volume, neurohormonal activation and inflammatory/fibrotic pathways in patients with T2D at high cardiovascular risk and non-T2D patients.
The Chinese Multi-provincial Cohort Study (CMCS)-Beijing project is a sub-study in CMCS participants from Beijing, which intended to investigate the progression and determinants of atherosclerosis and aging related health problems through repeat examinations. Exam 0 to Exam 3 have been conducted during 1992 to 2012. Exam 4 is scheduled in 2020.
Nearly nine-in-ten Americans overconsume salt. Black individuals are more prone to salt-sensitive hypertension. The central goal of the study is to determine if dietary sodium influences blood vessel function and nervous system regulation of blood pressure differentially in black, compared to white individuals. These findings may help to explain why high dietary salt causes increases in blood pressure more frequently in black, compared to white individuals. A secondary goal of this project is to also determine the role of lifestyle factors (i.e., sleep, physical activity, and nutrition) on potential baseline racial differences in cardiovascular function.
The rapid mobilization of cardiac surgery patients within the first 48 postoperative hours in the intensive care unit is common practice and decisive for the outcome, especially in this group (over 65 years). If sitting on the edge of the bed was successful, a standing attempt is usually made. Both can be accompanied by blood pressure dysregulations in the sense of hypotensive phases as well as dizziness. Postural control is the ability of the body to balance an upright body position under the influence of gravity.The aim of the study is to investigate whether training with the Galileo device by means of vibration on the soles of the feet and / or by changing the position to 15 ° can improve the postural control and thus the postoperative mobilization of patients.
The purpose of this research study is to determine if short-term consumption of a dietary ketone drink, which increases the blood circulation concentrations of beta-hydroxybutyrate, a ketone, affects blood vessel health and cognitive health in adults. Ketones are normally produced by the liver when people fast longer than 16-24 hours or eat a diet low in carbohydrates. Participants will be asked to randomly consume a dietary ketone drink and placebo (flavored water) for a 2-week period each in a crossover fashion with a 2-week washout period while maintaining habitual diet and physical activity patterns. The investigators hypothesize that consumption of a ketone drink will reduce BP and improve vascular health by reducing aortic pulse wave velocity and increasing brachial artery flow mediated dilation. Furthermore, they hypothesize that ketone consumption will improve cognitive health by increasing attention and processing speed.
