Filter by:Cardiovascular disease is a leading cause of death and disease in Chile. It explains 27.6% of the causes of death and 14% of disabled adjusted life years in the Chilean population. Low levels of physical activity and low levels of adherence to pharmacological therapy are major risk factors for cardiovascular disease in at-risk populations. This project will design and test the effectiveness of a mobile application based on gamification theory for improving cardiovascular disease control in a population of 900 primary care patients with moderate or high cardiovascular risk levels. A randomized controlled trial was designed to test the effect of the App in improving 30% of the levels of physical activity and adherence to pharmacological therapy and a significant reduction of 20% in cardiovascular risk levels.
This study sets out to evaluate a University of California-wide (Davis, San Francisco, and Los Angeles) quality improvement initiative to increase remote (home) blood pressure monitoring and improve blood pressure control for persons with hypertension. Participants at each site will be randomized to one of two types of remote monitoring: integrated versus manual. Participants using the integrated monitoring will have their home blood pressure readings sent directly to their participating health systems. Participants using the manual monitoring will record their own blood pressures and report them to their health care system as per usual care.
This is a prospective, multicenter, non-randomized, open-label clinical study of the safety and performance of the TIVUS™ System in subjects with uncontrolled stage 2 hypertension in order to assess the safety and effectiveness of the TIVUS™ System when used for renal artery denervation. The study will assess the acute and chronic safety of the procedure as well as the reduction in 24-hour ambulatory mean systolic blood pressure from baseline to 3 months after the procedure.
To assess efficacy, and safety of a single sustained release dose of the OTX-TIC drug product (2 travoprost dose strengths) in subjects with Open Angle Glaucoma (OAG) or Ocular Hypertension (OHT)
Laparoscopic Roux-en-Y Gastric Bypass (LRYGB) has been the most performed bariatric surgical intervention until a few years ago, due to its good results in terms of weight loss and remission of comorbidities such as hypertension, type 2 diabetes mellitus, dyslipidemia and obstructive sleep apnea syndrome. However, more than 25% of patients do not obtain the expected result. There is no uniform technique to perform a LRYGB, but traditionally it was constructed using a long alimentary limb (AL) and a short biliopancreatic limb (BPL). There is no current consensus on the ideal length of the LRYGB limbs. The distal gastric bypass at the expense of a longer biliopancreatic limb (LBPL-GB) could induce more excess of weight loss (EWL%), but with possible protein malnutrition depending on the length of the remaining common limb. The aim of this study is compare a LBPL-GB (BPL 150cm, AL 70cm) with LAL-GB (BPL 70cm, AL 150cm). PRIMARY OUTCOME: to evaluate if there are differences in weight loss. SECONDARY OUTCOME: to assess whether there are differences in both groups in remission of the most common comorbidities and in quality of life. DESIGN: multicenter, prospective, randomized study in blocks (1:1), blinded for the patient and to the surgeon up to the time of intervention, in patients with indication of RYGB for obesity (BMI>35 with associated comorbidity or BMI>40 with or without comorbidity, excluding those of BMI>50). Intervention: LRYGB type 1 (LAL-GB: 150cm ALand 70cm BPL) or type 2 (LBPL-GB: 70cm AL and 150cm BPL). The expected result is that the patients with LBPL-GB present better EWL%, and higher remission of their comorbidities than the comparison group
Trial name) The differential effects of antihypertensive drugs on central blood pressure: comparison between beta-blocker(BB) and angiotensin receptor blocker ARB) Objectives) To evaluate the effect of BB, which has vasodilatory effects, on CBP by comparison between ARB, one of the most widely used class of antihypertensives. Study design) A multicenter, prospective, randomized, controlled, open-label clinical trial for hypertension patients. Patient enrollment) 110 patients will be enrolled at 2 centers in South Korea. Patient follow-up) Patients will go through an initial washout period of two weeks prior to randomization. After pre-medication baseline visit and randomization, clinical follow-up will occur at 4, 8, 12 weeks after initial administration of randomized drug. The follow-up visits are office visits. Primary endpoint) Reduction in CBP at 12 weeks. Secondary endpoints) Clinical events including adverse reactions to the drugs.
A two-arm randomized controlled trial to evaluate whether a gamification intervention plus involvement of a supportive partner (social support) and sending reports to physicians (accountability) increases medication adherence in patients with hypertension and hyperlipidemia. The study will randomize 84 patients with hypertension, hyperlipidemia, and a history of poor medication adherence seen in a single Penn Medicine clinic to an 18-week gamification intervention or to attention control text messages alone.
Intermittent fasting is a method of restricting calories over a defined period of time and includes regimens such as whole-day fasting, alternate-day fasting, and time-restricted feeding. There is emerging evidence that intermittent fasting or energy restriction might be more beneficial than continuous energy restriction for some risk factors. The effect of intermittent fasting on risk factors associated with obesity, diabetes, and cardiovascular disease, however, is not clear. The European Association for the Study of Diabetes (EASD) has yet to make any recommendations regarding the role of intermittent fasting in the management of diabetes. To inform the update of the EASD Clinical Practice Guidelines for Nutrition Therapy, tthe Diabetes and Nutrition Study Group (DNSG) of the EASD has commissioned a systematic review and network meta-analysis of randomized controlled trials of the effect of different intermittent fasting strategies on established cardiometabolic risk factors. The findings generated by this proposed knowledge synthesis will shape guide current guidelines and improve health outcomes by educating healthcare providers and patients, and by guiding future research design.
Hypertension (HTN) rates have increased worldwide, but the most significant increase in the incidence of morbidity and mortality has been in African Americans (AA)1,2 (43% vs 27% for other U.S. population groups). Despite evidence of positive benefits from lifestyle modification (healthy diet, reduced sodium intake, increased physical activity, smoking cessation) and prescribed antihypertensive therapy (AHT) many AA with HTN do not adhere to their treatment regimens. Consistent, effective lifelong self-management is required to sustain optimal BP control and thus reduce morbidity and mortality. Self-managing HTN to a blood pressure (BP) <130/80 mm Hg presents challenges such as juggling multiple medications and health care providers, dealing with complex recommendations and treatment regimens, and coping with negative emotional states. Few studies have examined the biopsychosocial mechanisms that foster effective HTN self-management and resilience among AA living with HTN. Understanding the mechanisms that influence HTN self-management and resilience in AA holds the promise of new modifiable targets for behavior-change interventions. This study explores the relationship among resilience precursors on hypertension (HTN) self-management behaviors, stress response, and the effects that these relationships have on health outcomes-health-related quality of life (HRQOL) and blood pressure (BP) in African Americans (AA) with HTN over a 6-month period.
Study MIPAE - Melatonin and essential arterial hypertension. Study with dietary supplement, prospective and monocentric (randomized control trial). 1 mg/day of melatonin has been administered for one year to a group of patients suffering from essential hypertension (from at least one year) and who are already on antihypertensive therapy. This group has been compared with as many hypertensive patients on antihypertensive therapy to whom melatonin has not been administered. Each of the participants have been evaluated at the beginning of the study and after one year considering: - systolic and diastolic blood pressure; - echocardiographic values (Vivid Q, GE Healthcare); - applanation tonometry (SphygmoCor, AtCor Medical); - peripheral arterial tonometry (EndoPAT-2000, Itamar); - melatonin levels and total circulating antioxidant capacity after peripheral venous blood sampling. The aim of the study was to evaluate the antioxidant and vasoprotective effects of melatonin, evaluating both plasma changes and directly studying the possibility of a real remodeling and improvement of cardiac structures.
