Filter by:The goal of this clinical trial is to learn about the effects of phase-targeted auditory stimulation in depressed patients and healthy controls. The main questions it aims to answer are: - Is auditory down-phase stimulation efficient in improving depression symptoms as compared to sham stimulation? - Can mood and other outcomes be prospectively estimated by multi-parametric passive data? Participants will perform auditory stimulation using a wearable device at home and provide data on their phone usage and activity. Researchers will compare depressed patients and healthy participants to see if auditory down-phase stimulation effects them differently.
In this study, participants will receive, in randomized, double-blind fashion, an intragastric bolus administration of either (i) 300 mg quinine, (ii) 5 g L-isoleucine, (iii) a combination of (i)+(ii), or (iv) control, before 350 ml (500 kcal) of a mixed-nutrient drink, to evaluate the effects on postprandial blood glucose, gastric emptying, and the hormone, and appetite, responses to the mixed-nutrient drink. Study visits will be separated by 3-7 days and participants will receive one treatment per visit. On each study visit, the participant will be intubated with a nasogastric feeding tube. At t= - 60 min (08:30 am), a baseline blood sample, visual analogue scale questionnaire (VAS), and breath sample will be collected and quinine or control will be administered through the feeding tube. 30 min later (at t= - 30 min), L-isoleucine or control will be administered over 2 min after which the feeding tube will be removed immediately. At t = -45, -30, -15, and -1 min further blood samples will be collected and VAS completed. At t = -1 min, participants will consume, within 1 minute, a mixed-nutrient drink, labeled with 100 mg of 1-13C-acetate for measurement of gastric emptying by breath sampling. Blood samples, VAS, and breath samples will be taken at regular intervals between t = 0-180 min.
This is a randomized, placebo-controlled, cross-over study with 4 arms. Healthy and GH deficient adults ages 18-45 years will be studied. Arms will consist of 21-day treatment periods and be separated by 8-week washout periods. Subjects will receive, in random order: i) GH alone, ii) GH with liraglutide, iii) liraglutide alone and iv) placebo. Each phase of the study will consist of a 7-day baseline period including 2 days of testing and 21 days on therapy with visits on days 2, 7, 14 and 21. Testing before, during and at the completion of each arm will include blood sampling and assessments of insulin resistance, energy expenditure and body composition.
A Randomized, Double-blinded, Partial-open, Placebo and Active-controlled, Single and Multiple Dose-escalation Phase 1 Clinical Trial to Evaluate the Safety, Tolerability, Pharmacokinetic and Pharmacodynamic Characteristics of ID120040002 in Healthy Volunteers
The goal of this clinical trial is to test the Caregiver Interaction Profile (CIP) training program (Helmerhorst et al., 2017) promoting the relational quality between professional caregivers and children in daycare. The main questions it aims to answer are: - Does the CIP training program, compared to no training, improve the relational quality between daycare providers and children in daycare? - Does the CIP training program, compared to no training, foster children's social, emotional, and language development? Daycare providers assigned to the "training group" will participate in the CIP training program, which uses video-recorded interactions between the daycare providers and children in daycare to give feedback on the relational quality as observed in the videos. Daycare providers assigned to the "waiting list control group" will initially not take part in the training program but will receive the training after the study is finished. All daycare providers' daily interactions with the children in daycare will be filmed before and after the training in order to see if there has been a change in relational quality for the daycare providers in the training group (compared to the control group). Daycare providers in the training and control groups will also fill out questionnaires about the social, emotional, and language development of the children in their care. Researchers will compare daycare providers (and the children in their care) in the "training group" to daycare providers (and the children in their care) in the "control group" to see if the relational quality in the training group improves more than that in the control group as a result of the CIP training, and how that impacts the social, emotional, and language development of children.
This Phase 1, first-in-human, randomized, double-blinded, placebo controlled study is evaluating FB-001 in healthy volunteers (Part 1) and participants diagnosed with enteric hyperoxaluria (Part 2). Eligible participants receive investigational product and undergo safety monitoring, evaluations and subsequent follow-up after investigational product administration.
Observational, within subject study design with 1 pre and 2 post-fire exposure biomarker samples collected to assess exposure to toxicants from combustion emissions related to fighting a structural fire.
The purpose of this study is to determine the effect of obesity on cardiovascular responses during various breathing maneuvers.
Hypertension has been a serious problem among people from different ages in the last few decades, so by taking this in consideration we decided to search for specific risk factors that cause hypertension in young healthy adults, and to achieve that we are looking for pre-hypertension, obesity, and sedentary lifestyle among this group by using different scale tools and questionnaires.
This is a single-center study at the Cleveland Clinic Main Campus designed to study biomarkers in healthy individuals to identify novel mechanisms of platelet activation and how platelets drive vascular inflammation and thrombosis in diseases.
