Filter by:The investigators long-term goal is to better understand novel interventions to promote cardiovascular health in humans. The goal of the proposed research is to investigate whether there is sex-specificity in the effects of dietary capsaicin on mechanisms regulating nitric oxide (NO) bioavailability, its effect on key markers of cardiovascular (CV) health, including BP, macro- and microvascular function, and arterial stiffness. This knowledge will provide critical insight into the effects of dietary capsaicin on CV health and will guide future trials.
1. Primary outcome: To evaluate the dose response effects of watermelon flesh in regulating Blood Pressure (BP) in individuals with pre-hypertension. 2. Secondary outcomes: To study the dose-response effects of watermelon flesh intake on cardio-metabolic risk factors including plasma metabolic markers, lipid profile and nitrate/nitrite levels in individuals with pre-hypertension.
Hypertension is an increasingly important medical and public health issue. The prevalence of hypertension increases with advancing age to the point where more than half of people 60-69 years of age and approximately three-fourths of those 70 years of age and older are affected. The age related rise in SBP is primarily responsible for an increase in both incidence and prevalence of hypertension with increasing age. At present, it is estimated that about 1 billion people worldwide have hypertension (>140/90 mmHg), and this number is expected to increase to 1.56 billion by 2025. Because of the new data on lifetime risk of hypertension and the impressive increase in the risk of cardiovascular complications associated with levels of BP previously considered to be normal, the JNC 7 report has introduced a new classification that includes the term "prehypertension" for those with BPs ranging from 120-139 mmHg systolic and/or 80-89 mmHg diastolic. This new designation is intended to identify those individuals in whom early intervention by adoption of healthy lifestyles could reduce BP, decrease the rate of progression of BP to hypertensive levels with age, or prevent hypertension entirely. Prehypertension is not a disease category. Rather, it is a designation chosen to identify individuals at high risk of developing hypertension, so that both patients and clinicians are alerted to this risk and encouraged to intervene and prevent or delay the disease from developing. Individuals who are pre hypertensive are not candidates for drug therapy based on their level of BP and should be firmly and unambiguously advised to practice lifestyle modification in order to reduce their risk of developing hypertension in the future. The goal for individuals with prehypertension and no compelling indications is to lower BP to normal levels with lifestyle changes, and prevent the progressive rise in BP using the recommended lifestyle modifications.
The investigators are conducting an unblinded pilot randomized control trial of 250 persons living with HIV (PLWH), aged 18-65 years, who receive antiretroviral therapy care at Haitian Group for the Study of Kaposi's Sarcoma and Opportunistic Infections (GHESKIO), are virally suppressed, and have pre-hypertension (systolic blood pressure (SBP) 120-139 or diastolic blood pressure (DBP) 80-89 mmHg) to be randomized to early hypertension (HTN) treatment versus standard of care (SOC). Participants will be recruited from GHESKIO's HIV clinic. Eligible individuals will complete informed consent and be randomized to early HTN treatment vs. SOC. Participants in early HTN treatment will initiate amlodipine immediately versus those in SOC will initiate amlodipine only if they meet the HTN threshold (SBP ≥140 or DBP ≥90 mmHg) during the study period. All participants will be followed for 12 months.
In this RCT, up to 100 adults classified as pre-hypertensive will be randomized to either an artificial intelligence (AI) based lifestyle intervention group or an active control group with a 1 to 1 ratio. Both groups will receive an identical activity tracker (Samsung Galaxy Watch) and BP monitor (Omron Evolv). The AI intervention group will receive automated and personalized lifestyle recommendations based on their lifestyle (e.g. sleep, exercise and diet) and blood pressure (BP) data, involving an automated analytics engine using statistics and machine learning. The active control group will not receive these lifestyle recommendations. The investigators aim to assess objectively the effectiveness of the AI-based personalized lifestyle recommendations on the patients BP.
The Wald Outreach Center will partner with Medicine for the Greater Good (MGG) to implement this pilot project called Wald Outreach for Wellness (WOW), a blood pressure outreach wellness intervention in a retail setting.
New data suggests that isometric handgrip training (IHT) might become a novel tool in the treatment of hypertension. The main purpose of this research project is to evaluate the effects of home-based IHT on ambulatory blood pressure in older adults with pre-hypertension and hypertension. Eighty-four older adults with pre-hypertension and hypertension will be randomly distributed to one of three groups: home-based IHT, home-based aerobic exercise training (AET), or attention-control group (CON). Each intervention will have a total duration of 8 weeks. At baseline and after completing the intervention, patients will undergo the following evaluations: 24-hour ambulatory blood pressure, cardiorespiratory fitness, endothelial function, damage and repair, arterial stiffness, inflammatory biomarkers, autonomic function, physical activity levels, dietary intake and quality of life. A qualitative analysis will also be applied to enhance the understanding of the efficacy of this intervention from the patient's perspective.
The estimated prevalence of hypertension is approximately 29.0% in the United States during 2015-2016. Hypertension remains an important public health challenge in the United States because it increases the risk for other health conditions such as cardiovascular disease. Strong evidence has indicated that physical activity is associated with reduced risk of hypertension. Lifestyle change programs, including physical activity promotion and dietary modification, have been shown to effectively reduce the cumulative incidence of hypertension for individuals at-risk. However, it is challenging to maintain a high-level program. Recently, the consumer marketplace has been flooded with an array of wearable activity monitors, such Fitbit and Apple Watch, designed to enhance real time self-assessment and activity behavior change. These devices provide potential to serve as more cost effective and appealing intervention means for behavior change applications. Studies have examined the accuracy of the devices but little has been done to examine the monitors' feasibility as a behavior change strategy in and of themselves or as an adjunct to traditional methods (e.g., education and goal setting through a health coach), among people with hypertension. The real-time physical activity monitoring also provides an opportunity to build customized physical activity biofeedback for behavior change. Thus, there is an increasing interest to investigate their application as a behavior change strategy in isolation or as a complement to a more traditional intervention. The current study will recruit participants with hypertension and pre-hypertension. A Fitbit Charge HR will be provided to use over the intervention to all participants. They will be randomly assigned into Fitbit only and Fitbit plus (adding weekly personalized report and health coach consulting) groups for 3-months.
The prevalence of pre-hypertension and hypertension in the elderly is very high. Apart from medication, physical exercise training is a potential strategy to reduce blood pressure, however, the ability to perform exercise can be limited in the elderly. Hence, alternative non-pharmacological strategies to reduce blood pressure are necessary. Two interventions that have been shown to positively influence blood pressure are respiratory muscle training (RMT) and intermittent hypoxia (IH). Whether a combination of RMT and IH yields even better effects is currently unknown. Therefore, in this study, the effect of a single session of RMT with and without IH on blood pressure and associated cardiovascular parameters will be investigated in elderly subjects with pre-hypertension.
This study is 12 months long and consists of 5 visits at baseline, months 1, 3, 6, and 12. To determine eligibility potential subjects will have resting blood pressures (BP) measured on 2 occasions. Pre-hypertensive individuals will be invited to participate in the study. After informed consent is obtained, subjects will complete baseline visit consisting of a survey, resting BP, wear activity watch for 7 days ambulatory blood pressure monitor for 24-hours, collect saliva and urine samples. Subjects will then be randomly assigned to Tension Tamer (TT) or lifestyle education program delivered via smartphone (SPCTL) groups. At the remaining 4 visits subjects will again complete a survey, resting BP, wear activity watch for 7 days ambulatory blood pressure monitor for 24-hours, collect saliva and urine samples. Throughout the 12 months TT group will meditate twice daily and SPCTL group will log physical activity.
