Filter by:To explore how estrogen deficiency impacts the blood pressure (BP) and sympathetic nerve activity (SNA), and how it impacts the production of the key pro-inflammatory mediators such as Tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). It is hypothesized that estrogen deficiency increases BP, SNA and the pathway activities of the key pro-inflammatory mediators. Those effects are impacted through the downregulation of the estrogen receptor.
This is a first-in-human, randomized, double-blind, placebo-controlled, single ascending dose study in healthy volunteers. Kylo-11 will be evaluated in approximately 60 subjects to assess safety, tolerability, pharmacokinetics and pharmacodynamic effects.
Caffeine is one of the most widely consumed substances worldwide. This study looks to test and measure the changes in different biomarkers in the blood before and after having caffeine using capillary and venous blood sampling methods. A biomarker is a measurable indicator of biological processes. The primary goal of this clinical trial is to evaluate participant rate and adherence. It will also learn about how caffeine affects different biomarkers that may be related to cardiovascular disease. Finally, it will assess the accuracy of the capillary blood samples compared to the venous blood samples. The main questions it aims to answer are: - What is the feasibility of recruiting and retaining participants? - Are the study procedures appropriate to be translated to a larger future study? Researchers will compare caffeine to a placebo (a look-alike substance that contains no drug) to see if Participants will: - Be randomly assigned to the control group or the caffeine group. Individuals in the control group will be taking a placebo pill with no effect and those in the caffeine group will be taking 400mg of caffeine in pill form. - Be asked to undergo a fast of at least 8 hours overnight before taking two placebo pills or the 400 mg of caffeine via two caffeine pills. They will be required to stay fasted for 6 hours after taking the pill as well. The total time fasted will be at least 14 hours. - Have blood collected using three different methods before taking the two pills, 3 hours after taking the pills and 6 hours after taking the pills. The 3 methods include intravenous (IV) blood sampling, finger prick and collection on Whatman 903 Protein Saver Card and collection using the TASSO+ device. The TASSO+ blood collection device is a small capillary blood collection device that is designed to be easy to use and able to be used outside of a hospital/lab setting. Whatman 903 Protein Saver Cards are special filter paper with five circles for samples, that are designed for the collection and storage of blood.
A prospective, open label, multi-center, single arm, observational study designed to evaluate the acute safety and device performance of the Sapphire 3 0.85, 1.0 and 1.25mm diameter coronary dilatation catheter in predilatation of Chronic Total Occlusion (CTO) lesions during percutaneous coronary intervention. One hundred seventy (170) subjects will be enrolled with a target of one hundred fifty-three (153) evaluable subjects by the angiographic core laboratory at up to 15 clinical sites with the Sapphire 3 0.85, 1.0 and 1.25mm diameter PTCA dilatation catheter to pre-dilate CTO lesions in coronary arteries during their index procedure. All subjects will be screened according to the protocol inclusion and exclusion criteria and will be followed through study completion, which is defined as 24-hours post-procedure or hospital discharge, whichever comes first.
The CONNECT: "Developing a learning COmmunity to increase eNgagemeNt and Enrollment in cardiovascular Clinical Trials" is comprehensive, participant-centered learning community that provides tailored education on cardiovascular (CV) health and research participation; connects community members to CV-related research; and disseminates CV-related study findings. The overreaching goal of CONNECT is to improve participation of underrepresented communities in CV research, including as women, Black adults, and Latino adults, through increasing participants' clinical trial awareness, trust in biomedical research, and willingness to participate in clinical trials. CONNECT will use digital and community-engaged approaches to identify and recruit 1000 adults with cardiovascular disease or a cardiovascular disease risk factor to join CONNECT. Participants who join CONNECT will receive tailored educational information on CV health and research participation via text message. Participants will also have the opportunity to be matched to ongoing CV research studies based on basic demographic information and areas of interest. The educational information will be sent to participants for 12 months. The investigators hypothesize that CONNECT will increase participants' clinical trial awareness, trust, and willingness to participate in clinical trials and that the proportion of Black and Latin adults and women enrolled in trials that partner with CONNECT will be higher following the use of CONNECT for recruitment.
The goal of this clinical trial is to test two advices on alcohol drinking in more than 10.000 Spanish adult drinkers (men of 50 or more years and women of 55 or more years). The main question it aims to answer is to test the non-inferiority advice of a moderate alcohol drinking pattern on all-cause mortality and other chronic disease like cardiovascular disease, cancer or type 2 diabetes. Participants will receive during 4 years an advice to drink alcohol following a Mediterranean Alcohol Drinking Pattern (MADP): consuming alcohol in moderation, avoidance of binge drinking and preference for red wine. Researchers will compare those who will receive a MADP advice with those who will receive an advice on abstention to see if the advice on MADP is not inferior than the abstention advice to prevent all-cause mortality and other chronic diseases.
Heart failure (HF) is a global, public health issue that affects more than 63 million people worldwide; this burden is expected to increase substantially as the population ages. Despite advancements in treatment, a HF diagnosis still leads to significant morbidity and mortality; there is also an immense impact on patients' health-related quality of life (HRQoL). Dapagliflozin was recently granted approval for heart failure by the European Commission, regardless of ejection fraction and whether the patient has diabetes. Real-world observational data are necessary to describe dapagliflozin use in real-world settings in order to assess treatment patterns, HF symptoms and their impact on physical limitation, HRQoL and work productivity, as well as health care utilization of patients treated with dapagliflozin in this setting under local treatment standard conditions in Germany.
The goal of this randomized, double-blind, placebo-controlled clinical trial is to investigate the immunological effects of influenza vaccination outside of the influenza season on arterial inflammation in patients with a recent acute myocardial infarction (AMI). The primary objective is to compare the effects of influenza vaccination to those of a placebo in reducing post-myocardial infarction coronary inflammation as measured by coronary computed tomography angiography (CCTA). The main questions it aims to answer are: Does influenza vaccination reduce arterial inflammation as measured by CCTA at week 8 after percutaneous coronary intervention (PCI) in comparison to baseline? Does influenza vaccination modulate systemic inflammation as measured by blood biomarkers and in-vitro challenge tests at week 8 after PCI in comparison to baseline? Researchers will compare the effects of influenza vaccination with those of a placebo.
The study conducted a health survey among Thai adults in 2022 and found a significant increase in obesity and nonalcoholic fatty liver disease (NAFLD), leading to metabolic-associated steatotic liver disease (MASLD). The prevalence of NAFLD was 19.7%, with higher rates in individuals with metabolic syndrome and diabetes. MASLD is associated with insulin resistance and genetic polymorphisms, particularly the patatin like phospholipase domain containing 3-rs738409 variant. Additionally, physical activity was inversely related to liver disease risk, with higher step counts associated with reduced incidence of NAFLD and liver-related mortality. The study aims to investigate the impact of dietary advice and pedometer use on physical activity levels and health outcomes in MASLD patients over 24 weeks.
The overall objective is to establish the first-of-its-kind longitudinal cohort of pregnant women, biological fathers/partners and offspring from pregnancies achieved by frozen embryo transfer (FET), fresh-embryo transfer (fresh ET) and naturally conceived (NC) to investigate maternal cardiometabolic profiles, fetal growth patterns and placental function during pregnancy as well as metabolic and endocrine health in the offspring. Additionally, the aim is to explore genetic and epigenetic patterns in placenta, fetus and parents. As secondary objectives, the investigator group will examine telomere length and minipuberty hormones in children born after FET, fresh-ET and NC.
