Filter by:The Guangzhou Women's Health Cohort Study aims to explore the health trajectory and factors contributing to the health of women aged 35-64 in Guangzhou. Based on multiple population health registration data platforms, data of the cohort will provide information about the health of women across the lifespan, facilitating the decision-making process by local government . The cohort is progressing steadily, and the goal is to build a large women cohort covering 11 administrative districts of Guangzhou with a scale of 1 million by 2030.
The Life University Center for Chiropractic Research is conducting a research study to better understand the physiological differences, in terms of Autonomic nervous system function, between individuals with Hypertension and control individuals with out hypertension. Data will be gathered using Heart Rate Variability (HRV), and Galvanic Skin Response (GSR). A series of tests will be conducted to elicit Autonomic Nervous system responses. These tests include Cold Face Test (mammalian dive reflex), Cold Pressor test, Sit to stand, and the Valsalva maneuver.
People affected by multiple chronic diseases have a greater chance of hospitalization, longer hospital stays, worse general health, worse physical and mental function and lower functional capacity, with an average risk of 50% of functional decline with each additional condition. The frequency of multimorbidity is higher in older, inactive women, who live in urban areas in low- and middle-income countries, the most affected by multimorbidity. The practice of physical exercise is an important component in the prevention of multiple chronic diseases, in which lower levels of physical activity were associated with an increased prevalence of multimorbidity in women aged 16 to 24 years. And regardless of the presence of multimorbidity, engaging in a healthier lifestyle, including regular physical activity, was associated with up to 7.6 more years of life for women, improving the individual's general health status even when multimorbid. The hypothesis is that multimorbid women have a worse general health status when compared to women without multimorbidity, but aerobic exercise will be able to improve health parameters in 12 weeks of training. This is a quasi-experimental clinical trial with a 12-week aerobic training intervention in postmenopausal women with and without cardiometabolic multimorbidity. Participants were allocated into groups according to the amount of cardiometabolic diseases, with the Morbidity group (MORB) being composed of women with one or no chronic cardiometabolic disease and the Multimorbidity group (MULTI) with two or more chronic cardiometabolic diseases. The assessments of arterial stiffness, 24-hour ambulatory pressure, blood pressure variability, heart rate variability, lipid and glucose profile, body composition and climacteric symptoms were performed before and after the training period. The study was carried out at the Laboratory of Cardiorespiratory and Metabolic Physiology at the Faculty of Physical Education of the Federal University of Uberlândia, Uberlândia, Brazil and approved by the Ethics Committee for studies in humans (CAEE: 12453719.1.0000.5152). All participants signed a consent form. The experiments followed the principles of the Declaration of Helsinki. The program consists of aerobic physical exercises performed three times a week on non-consecutive days for 12 weeks with an intensity of 65% to 75% of the reserve heart rate.
Emergency patients often have uncontrolled asymptomatic hypertension upon discharge from the emergency department. This 3-arm randomized controlled trial will evaluate the impact of nurse telehealth encounters and remote patient monitoring, using a software called Vital Tech, on blood pressure control and primary care engagement.
The target population for our study is healthy nulliparous pregnant women (first pregnancy) between the 12-16 week of pregnancy. If a subject is eligible, written consent will be obtained by person to person contact. Eligible participants will be randomized to receive either daily L-citrulline supplementation or placebo.
The aim of this research study is to assess the safety and feasibility of lowering intraocular pressure (IOP) using an experimental study drug, JV-GL1.
Coronavirus disease 2019 (COVID-19) is a pandemic infection caused by a virus called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Because SARS-CoV-2 is known to require the angiotensin-converting enzyme 2 (ACE-2) receptor for uptake into the human body, there have been questions about whether medications that upregulate ACE-2 receptors might increase the risk of infection and subsequent complications. One such group of medications are anti-hypertensives that block the renin-angiotensin system, including both angiotensin converting enzyme inhibitors (ACEi) and angiotensin II receptor blockers (ARB). Both ACEi and ARB are widely used for the treatment of hypertension. Early reports from China and Italy suggest that many of those who die from COVID-19 have a coexisting history of hypertension. Consequently, there have been questions raised as to whether these 2 types of blood pressure medication might increase the risk of death among patients with COVID-19. However, it is well known that the prevalence of hypertension increases linearly with age. Therefore, it is possible that the high prevalence of hypertension and ACEi/ARB use among persons who die from COVID-19 is simply confounded by age (older people are at risk of both a history of hypertension and dying from COVID-19). Whether these commonly prescribed blood pressure medications increase the risk of COVID-19 or not remains unanswered. Statements from professional cardiology societies on both sides of the Atlantic have called for urgent research into this question. Our study aims to randomize patients with primary (essential) hypertension who are already taking ACEi/ARB to either switch to an alternative BP medication or continue with the ACEi/ARB that they have already been prescribed. Adults with compelling indications for ACEi/ARB will not be enrolled.
Cardiovascular disease (CVD) is the leading cause of death worldwide. Hypertension is a well-established risk factor for the development of CVD. Lifestyle modifications, including exercise, remain the cornerstone of blood pressure (BP)-lowering strategy. Swimming has long been a popular recreational activity for exercise, and is recently gaining widespread recognition as an effective option in maintaining and improving cardiovascular health. Previous studies that involved pool swimming as an intervention (versus no pool swimming) demonstrated favorable benefits of the former on BP reduction. However, no studies to date have specifically investigated the effect of cold-water sea swimming on BP. Indeed, the naturally lower water temperature in the sea may engender a 'cold water immersion' experience in sea swimmers with subsequent stress physiology, which have been shown to exert unique effects on cardiovascular hemodynamics. This study primarily aims to determine the impact of cold-water sea swimming on BP in a group of habitual sea swimmers in Galway who will be randomly assigned to either continue or stop swimming for 4-6 weeks. Other objective and subjective health benefits to sea swimming will also be explored in this study. Given the ubiquitous nature of this activity in the Irish general public, particularly in Galway, this study has potential from a public health perspective, and would add to the literature base pertaining to the benefits of sea swimming on cardiovascular health.
This study evaluates the effect of slow and deep breathing on lowering blood pressure in women with pregnancy-induced hypertension. Slow and deep breathing will be practised daily for 10 minutes from enrolment until the woman gives birth. This feasibility study aims to investigate the practicality of conducting a proposed future randomised controlled trial.
Methamphetamine is misuse if classified as a "likely" risk factor for pulmonary arterial hypertension (PAH). Nevertheless the actual prevalence of and a screening strategy for PAH in methamphetamine users have not been established. In this study, the prevalence of PAH will be investigated and its independent risk factors among methamphetamine users will be identified.
