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 first purpose of this study is to characterize the relationship among propulsion workload, self-selected propulsion speed, and propulsion kinetics/kinematics. The second purpose is to assess the between days repeatability/reliability of the above outcomes. There are no hypothesis This is a repeated measures clinical trial. All participants will complete the following: 1) Acclimation to propelling a manual wheelchair on a wheelchair ergometer; 2) Graded exercise test on the wheelchair ergometer to 80% of age adjusted estimated maximal heart rate; and 3) N=20 one minute propulsion bouts on the wheelchair ergometer.
There has been increasing interest in natural dietary supplements that may support healthy cognition. Recent studies have demonstrated promising effects of bioactive phytochemicals (e.g., polyphenols) on cardiovascular and endocrine health outcomes. As such, an increasingly intriguing line of inquiry is whether materials high in these compounds may also have effects on psychological measures. Preliminary evidence suggests that polyphenols may improve cognition, for example, particularly in aging populations. Whole coffee cherry extract (WCCE; otherwise known as the generally-recognized-as-safe (GRAS) supplement Neurofactor(TM)), is a proprietary, safe, powdered extract of whole coffee cherries from coffea arabica with high levels of polyphenols and substantially low (<2%; <4mg) levels of caffeine. WCCE has been previously associated with increased serum concentrations of both circulating and exosomal brain derived neurotrophic factor (BDNF), in addition to increased alertness and decreased fatigue. However, few well-powered and well-designed studies have been conducted despite the mounting preliminary evidence. Here, the investigators propose a study to examine the long-term effects of a 200mg dose of WCCE on measures of cognition.
The objective of this study is to evaluate the use of the ABTHERA ADVANCE for patients requiring open abdomen due to necrotizing pancreatitis. The institutions traditional approach is to use the ABTHERA Open Abdomen dressing with Wittmann patch. However, the ABTHERA ADVANCE has shown in vitro to have improved tension on the abdominal wall that may obviate the need for costly Wittmann patch placement.
The overall objective of this mixed-methods proposal is to answer the focused research question: What tailoring is necessary and sufficient to achieve optimal engagement with and efficacy of Sleep Healthy Using the Internet (SHUTi) for caregivers? The SHUTi program is a fully-automated Internet-delivered cognitive-behavioral therapy for insomnia (CBT-I) program. We will identify caregiving-related user- and environment characteristics that affect the use and impact of SHUTi, and other Internet interventions more broadly, for caregivers. We will recruit 100 high-intensity caregivers with insomnia to complete a baseline assessment of insomnia and caregiving context. Caregivers will then receive access to SHUTi in an open-label trial. At the end of the 9-week intervention period, caregivers will complete post-assessment and be categorized according to their level of engagement with the 6 SHUTi intervention lessons (or weekly "Cores"). We will test whether caregivers' engagement with SHUTi (i.e., being a non-user vs. incomplete user vs. complete user) is associated with their caregiving-related user characteristics (i.e., caregiving strain, self-efficacy, and guilt) and environment characteristics (i.e., proximity to care recipient; care recipient functional, cognitive, and behavioral status; caregiving tasks). Caregivers' barriers to and motivations for SHUTi engagement will be described from open-ended survey responses specific to participants' level of engagement as part of post-assessment. We will identify non-users' barriers to SHUTi adoption, the extent to which barriers were related to caregiving, and what modifications may have increased their motivation to try SHUTi. We will also identify users' (incomplete and complete) SHUTi usage barriers and motivations, the extent to which these were related to caregiving, and how tailoring may improve usage by increasing salience to caregivers. Thematic coding will also examine how caregivers' recommendations generalize to other evidence-based digital health interventions. Among caregivers using SHUTi, we will test whether the effects of SHUTi on cognitive mechanisms of change targeted by SHUTi (i.e., more adaptive sleep beliefs, internalized sleep locus of control) are associated with differences in caregiving-related user or environment characteristics.
The study will compare the short-term clinical performance and wearer and practitioner acceptability of a new-to-market spherical daily disposable (DD) hydrogel soft contact lens to a currently marketed spherical DD hydrogel soft contact lens.
The purpose of this study is to evaluate the effectiveness of the oral rinse comparing to MucoPEG™ and Biotene®. This is a randomized open-label crossover study with 42 patients receiving treatment. Patients will be randomly assigned to receive either the MucoPEG™ or the Biotene® Dry Mouth Gentle Oral Rinse in the first period. Patients will use the assigned oral rinse two times a day for two weeks. Patients will switch to the other treatment after a wash-out period of one week.
This is a randomised, double-blind, placebo-controlled, multi-center sequential phase 2b and Phase 3 study to evaluate the efficacy and safety of AZD4831 administered for up to 48 Weeks in participants with heart failure with left ventricular ejection fraction > 40%. The study will consist of 2 separate parts, Part A and Part B, approximately 660 participants will be randomised in Part A, 820 in Part B.
This is a multicenter, randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study in patients with a primary diagnosis of MDD according to criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) who have an inadequate response to ongoing ADT.
The purpose of this study is to evaluate safety and tolerability of JNJ-67484703 administrations in participants with active rheumatoid arthritis (RA).
The objective of this study is to evaluate safety and effectiveness of the Lacrosse NSE ALPHA coronary dilatation catheter during PCI in subjects with stenotic coronary arteries.
