The aim of this study is to test the feasibility and effectiveness of a 16-week online behavioral weight loss program compared to usual care to promote weight loss in the postpartum period among women with cardiovascular risk factors. The investigators will also be testing different behavioral strategies to recruit postpartum women to the study, including 2 email recruitment strategies and 2 mailer recruitment strategies, informed by behavioral design.
The purpose of this study is to evaluate the safety (in the eye and throughout the body) and effectiveness of nebivolol (0.5 and 1 percent) and timolol (0.5 percent) eye drop suspensions. These eye drops will be compared to timolol 0.5 percent eye drop solution in participants with open angle glaucoma (the most common type of glaucoma) or high eye pressure (ocular hypertension).
In preparation for a future mechanistic study, investigators now propose to test the specific hypothesis that carnitine consumption is not reduced in PAH, that plasma carnitine levels are stable over time in PAH and that carnitine supplementation in PAH can increase plasma carnitine and thereby delivery of carnitine to the RV and possibly improve RV function. Investigators propose three aims in humans to test this mechanistic hypothesis, 1) Measure the oral consumption of carnitine in human PAH. This aim will use food diaries and carnitine supplement use questionnaires in PAH patients to test the hypothesis that carnitine supplementation is uncommon in PAH and food consumption is adequate. Aim 2) Measure the stability over time in plasma carnitine levels in PAH patients. This aim will test the hypothesis that plasma carnitine is not affected by disease severity and is stable over time in PAH patients. Investigators will measure plasma carnitine concentration and markers of fatty acid oxidation at Visit 1 and Visit 2. 3) Perform a mechanistic pilot study using carnitine supplementation to enhance circulating carnitine in PAH. This small pilot study will test the hypothesis that carnitine supplementation increases plasma carnitine (primary endpoint) and will test for physiologic effects using six minute walk testing, echocardiography and plasma markers of lipid metabolism.
This is a randomized, double blind, 2-period, non placebo-controlled crossover study in patients with moderate to severe OSA and controlled hypertension, comparing atomoxetine with AD113
This is a randomised, double-blind, placebo-controlled, dose escalation study to evaluate the safety, tolerability, and PK of single and multiple inhaled doses of imatinib inhalation solution (AER-901) in healthy adult volunteers. This study consists of 3 parts and an optional fourth part.
Background Hospital-based walking exercise tests are routinely used in patients with pulmonary hypertension to assess functional ability and disease progression over time. We are seeing a greater emphasis on non-face-to-face clinical assessments, where such tests cannot be conducted. It is important to identify alternative tests which can be which can be conducted by patients at home and used to support clinical decision making. Aim To test the safety of the 1-minute sit-to-stand test in patients with pulmonary hypertension and its comparability with hospital-based walking exercise tests. Methods A sample of 75 patients attending hospital appointments will carry out an Incremental Shuttle Walk Test, followed by a 1-minute sit-to-stand test after a 30 minute rest. Data will be analysed for safety and comparability between the 2 tests. In the event of favourable findings (safety and comparability) from the hospital-based testing, a further sample of patients will be asked to perform the 1-minute sit-to-stand test in the home setting
Beta-blockers represent a cornerstone for the treatment of coronary artery disease (CAD). Their protective effect is based on the negative inotropic and chronotropic features, which have been tested in a large number of randomized controlled trials, both in patients with myocardial infarction (MI) and in those with stable angina, demonstrating a reduction of adverse cardiovascular events, a relief of symptoms and a reduction of myocardial ischemia However, considerable interpatient variability in response to β-blockers has been reported which indicates that a considerable proportion of β-blocker-treated patients do not achieve the warranted cardio protection with β- blockers. This highlights the importance of identifying biomarkers associated with variability in response to β-blockers to improve the current approach for β- blocker selection, which seems to be suboptimal. This study aims to study the effect of polymorphism in adrenergic beta receptors on beta-blocker response in Egyptian patients.
WHO identifies as an important risk factor and potentially modifiable to high sodium intake (>2g/day 5g salt/day). Also, an insufficient consumption of potassium ( 3.5 g/day).Therefore, the results of this research could be the regional basis that is required to generate evidence, that designs strategies and recommendations for the prevention or decrease in the progression of high blood pressure. The reduction in the consumption of salt in the diet could comply with the recommendations established by international agencies. In addition, to favor the beginning of lifestyle changes, as well as other modifications that will have a positive impact on health.In population highly vulnerable to the campaigns of large industries that favor the consumption of processed food. However, it is unknown what is the effect of reducing foods high in sodium in populations in different regions of Mexico, estimated by 24 hour urine sodium excretion. Therefore, the present study aims to answer the following questions: What impact does an intervention aimed at the decrease in sodium intake, in young university students on blood pressure and the quantification of the excretion of sodium and urinary potassium of 24h? What is the association between body mass index, blood pressure and sodium reduction in the intervention vs control group? To assess the impact of an intervention aimed at reducing sodium intake through education as general recommendations for limiting specific foods high in sodium, in university students on blood pressure and quantification of urinary sodium and potassium excretion of 24h. Specific objectives Assess sodium intake between the intervention group and the control group by estimating 24-hour urinary sodium excretion. secundary objectives Evaluate the effect between the intervention group and the control group on blood pressure. To assess the levels of potassium excretion in the intervention and control groups. To evaluate the association between body mass index, blood pressure and sodium reduction in the intervention and control groups.
This is a first-in-human, single-blind, placebo-controlled, single-centre study designed to assess the safety and tolerability of PDNO in healthy male and female subjects. In addition, the exposure of 1,2 propanediol (PD) will be evaluated. There are 2 parts to the study: Part I: single ascending dose (SAD), 7 cohorts, 30 minutes intravenous (i.v.) infusion of placebo followed by 1-hour i.v. infusion of PDNO to assess safety, tolerability and PD exposure in healthy male and female subjects. Part II: ascending doses of PDNO in 2 cohorts, 30 minutes i.v. infusion of placebo followed by 3 ascending doses of PDNO in cohort 1 and 3 ascending doses of PDNO in cohort 2. The first 2 doses in each cohort will be i.v. infused for 30 minutes whereas the last will be i.v. infused for 3 hours to assess safety, tolerability and PD exposure in healthy male and female subjects. If indicated by emerging data and recommended by the internal safety review committee (iSRC), 2 additional dose groups/cohorts (4+4 subjects) may be added to Part I and 1 dose group/cohort (4 subjects) may be added to Part II.
