There are about 173942 clinical studies being (or have been) conducted in United States. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The objective of the study is to review performance of water soluble contrast study in patients admitted with Small Bowel Obstruction(SBO), will improve quality and safety, and decrease length of stay and morbidity.
The specific aims of this proposal are to 1) develop online food retail nudges to discourage sugary drink purchases and promote healthier substitutes; 2) examine the impact of online store nudges on purchases of sugary drinks in an online randomized controlled experiment with low-income parents, including Supplemental Nutrition Assistance Program (SNAP) and Women, Infants, and Children (WIC)-participating parents, of children age 1-5 years; and 3) disseminate findings to retailers, including those participating in the SNAP Online Purchasing Pilot.
This is a cross-over randomized study to validate the Sponsor investigational medical device against measurements of glymphatic function from MRI-based neuroimaging, EEG, blood biomarkers and cognitive tests in healthy older volunteers.
Recently, various electronic lifestyle activity monitoring devices (ELAM) are increasingly commercially available. However, the quality and reliability of the data from ELAM are unclear, compared with polysomnography (PSG), which is the gold-standard sleep assessment method. Thus, combining ELAM with PSG will validate ELAM and improve its clinical and research utilization. The investigators propose to conduct this study to validate ELAM device for sleep assessment. The investigators will compare Belun Ring data collection and overnight in-lab PSG measures of Sleep-Disordered Breathing (SDB) and sleep architecture in adults with obstructive sleep apnea (OSA) symptoms. The investigators propose to recruit a total of 40 participants with symptoms of OSA. The overall accuracy, sensitivity and specificity of Belun Ring to assess SDB and sleep architecture will be validated by using PSG analysis as a gold standard.
Activated charcoal (AC) is an established, effective means of gastrointestinal decontamination. Providers give it to patients who have ingested something that is thought to be potentially poisonous to prevent it from being absorbed. However, one limitation to its use is palatability of the AC for the patient, potentially limiting how much, if any, is taken. Other studies have suggested that mixing AC with various substances improves the rating on various scales (taste, etc). An important question is whether mixing the AC with other substance effects the ability of the AC to bind to xenobiotic in the gut. This small study investigates whether mixed cola with charcoal affected its ability to prevent the absorption of acetaminophen. It also performs a survery to see if participants preferred the AC-cola mixture. The investigators hypothesize that the AC will be equally as effective with cola as without. The investigators also hypothesize that participants will prefer the AC-cola mixture.
Walking with age becomes both slower and less 'automated', requiring more attention and brain resources. As a result, older adults have a greater risk of negative outcomes and falls. There is an urgent need to identify factors that can help compensate for these harmful factors and reduce walking impairments, as there are currently no effective treatments available. Investigators have recently discovered that ~20% of older adults maintain fast walking speed even in the presence of small blood vessel brain changes and leg problems, thus appearing to be protected against these harmful factors. The investigators work suggests that the brain dopamine (DA) system may be a source of this protective capacity. Investigators have also shown that lower levels of dopamine are associated with slow walking. Investigators will be investigating the role of dopamine on slow walking and other parkinsonian signs in this double-blinded, placebo-controlled study using detailed clinical assessment, assessment of dopamine activity, and clinical interventions.
Single site, prospective, double-masked, randomized-controlled, two-arm study of the dry eye symptoms as well as corneal and conjunctival staining in subjects using 2 different eyedrops. Subjects will be assessed at a screening visit, and 2 follow-up visits. Clinical evaluations will include patient questionnaire, tear-breakup time, and slit lamp exam.
The goal of the study is to determine the acute and short-term supplementation effect of a commercially available theacrine-containing supplement (NAD3) on numbers of various circulating stem cell populations in older adults.
The overarching goal of this study phase, Phase I component is to configure Computerized Chemosensory-Based Orbitofrontal Networks Training (CBOT) into Computerized Chemosensory-Based Orbitofrontal Networks Training for Treatment of Pain CBOT-Pain (or CBOT-P) for rapid and sustained reduction of Pain, Negative Affect (NA) and Cognitive Impairments. The investigators aimed at first establishing if stimulation parameters targeting key olfactory regions, and their associated networks, paired with tasks that synergistically activate the orbitofrontal cortex (OFC) would have significantly different acute (< 7 days) effects in pain and NA intensity reductions. The hypothesis is that the short burst paradigm will more effectively activate the medial OFC and its functional connectivity with medial temporal affective networks, and result in greater reduction of affect and pain severity ratings after 7 days. The investigators will further examine if enhancing the odor regimen with beta-caryophyllene (BCP) content would have more dramatic effects in acute relief of pain, NA, and cognition. Aim 1.1: To optimize CBOT-P stimulation parameters and olfactory stimulants for pain, affect and cognition in CP with and without high NA. This is a 14-day prospective study, in which fMRI and rs-fMRI will be acquired at baseline and day 7 during exposure to short vs long-burst CBOT stimulations. This is followed by daily treatment with short-burst versus long-burst CBOT paradigm over 14 days, during which pain and NA measures will be recorded daily by the subjects, and assessed by train research staff at baseline, day 7 and day 14. Aim 1.2: To determine if CBOT regimen optimized with BCP content produces stronger and faster pain and affective response. This is a 14-day prospective study design, in which daily treatment of CBOT-PLUS (i.e., CBOT with BCP) will be compared against daily treatment with CBOT without BCP enhancement (CBOT). Subjects and clinicians are blinded to the assigned arms. Pain and NA measures will be recorded daily by the subjects and assessed by trained research staff at baseline and day 14.
The goal of this clinical study is to test the tolerability of oxylanthanum carbonate (OLC) in patients with chronic kidney disease on hemodialysis and have hyperphosphatemia (too much phosphorus in their blood). The main question it aims to answer is whether patients taking OLC for hyperphosphatemia are able to tolerate the drug. Participants will continue with their scheduled dialysis treatments and replace their current phosphate binder drug with OLC.
