Filter by:The goal of this study is to pilot test a 12-week behavioral intervention among perimenopausal Latinas (age 40-55 years) that integrates evidence-based education with physical activity, stress management, and coping skills training to: 1) reduce cardiovascular disease (CVD) risk factors and arterial stiffness; 2) improve nutrition, physical activity, and sleep behaviors; and 3) improve stress management, coping strategies, and self-efficacy. This study will recruit participants from two community groups: one group will be randomly assigned to complete the intervention; the other will be a wait-list control.
The aim of our study is to assess the Cardiovascular risk and the quality of the arteries by comparing the Coronary Calcium Score SCC measured with a CT scann and the Pulse Wave Velocity PWV measured with pOpmeter for the prognosis at 6 months of clinical events. Is there a superiority of PWV compared to SCC:
Inadequate sleep is an independent risk factor for metabolic abnormalities (such as obesity, insulin resistance, and hyperglycemia). Women report sleep disruption during the menopause transition (perimenopause) and into the postmenopausal years. Sleep disruption is one of the primary reasons why midlife women seek medical care, with up to 60% reporting significant sleep disturbances (e.g., trouble falling asleep, early morning waking, and hot flashes/night sweats). Despite the majority of women experiencing sleep disruption, no study has investigated the molecular mechanisms linking sleep disruption and the changes in metabolism that coincide with menopause.
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.
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.
Regular physical activity should be the essence of treatment in patients with cardiovascular risk factors. Unfortunately, these interventions are usually insufficiently promoted and therefore have only limited efficacy. The aim of the study was to determine the benefits of nurse led intervention to promote physical activity in sedentary older adults with cardio-vascular risk factors in the outpatient setting. Eligible patients are randomized in a 1:1 fashion to receive nurse led tutorial on life-style modification including pedometer hand-out with a daily goal of at least 7000 steps and supporting phone calls (study group) or without a goal or calls (control group). The primary end-point of the study is change in body weight. Secondary end-points include changes in resting heart rate, systolic and diastolic blood pressure, total cholesterol and fasting glucose and clinical outcomes at 3 months follow-up.
Gut microbiota has a role in cardiovascular disease and recent findings in rodents show dietary salt can negatively alter gut microbiota composition. High salt intake is a risk factor for cardiovascular disease. Americans consume dietary salt in excess of Dietary Guidelines and American Heart Association recommendations. The objective of this project is to investigate the influence of high dietary salt consumption on the gut microbiota composition in men and women.
Prolonged sitting may pose a public health risk through its effects on the cardiovascular system, and may lead to impaired whole-body cardiovascular health, which includes both vascular and cerebrovascular function. These effects may interact with other environmental variables, such as stress. However, no study has investigated the combined effect of a mental stressor and prolonged sitting on vascular and cerebrovascular function. The combined effect of prolonged sitting and mental stress may lead to an exacerbated effect on vascular, cerebrovascular, and executive function. The investigators hypothesize that mental stress with the addition of prolonged sitting [PS] will result in a greater increase in peripheral, central and cerebral arterial stiffness and elicit a decrease in cerebral perfusion, total blood flow to the brain, middle cerebral artery velocity and executive function, compared to mental stress without prolonged sitting [CON]. The findings from this study may result in a public health message regarding sedentary behavior and stress, and will help elucidate the mechanisms behind acute vascular, cerebrovascular, and cognitive dysfunction during prolonged sitting.
