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 goal of this system identification experiment is to estimate and validate dynamical computational models that can be used in a future a multi-timescale model-predictive controller. System identification is an experimental approach used in control systems engineering, which uses random and pseudo-random signal designs to experimentally manipulate independent variables, with the goal of producing dynamical models that can meaningfully predict individual responses to varying provision of support. A system identification is single subject/N-of-1 experimental design, whereby each person is their own control. This 9-month system identification experiment will experimentally vary daily suggested step goals and provision of notifications meant to inspire bouts of walking during different plausible just-in-time states. Results of this system identification experiment will then enable the development a future multi-timescale model-predictive controller-driven just-in-time adaptive intervention (JITAI) intended to increase steps/day. The system identification experiment will be conducted among N=50 inactive, adults aged 21 or over who have no preexisting conditions that preclude them from engaging in an exercise program, as determined using the physical activity readiness questionnaire.
To assess the magnitude and duration of reduction in RNS recorded Detections and Long Episodes following intranasal administration of Valtoco®. All participants will have been implanted and treated with an RNS system for clinical purposes and regularly upload Detection and Long Episode data on a regular basis as part of regular clinical treatment. Participants will come to the clinic and be administered a single dose of Valtoco® via nasal spray. RNS recorded Detections and Long Episodes before and after Valtoco® administration will be compared. This is a pilot study, so all outcomes are exploratory.
The purpose of this study is to better understand how hypoxia (low oxygen) affects resting and exertional right ventricular function in healthy individuals.
Chamomile may possess anticoagulant effects based on the presence of coumarin-like compounds within the flower. This randomized complete crossover study will investigate the impact of chamomile ingestion acutely on coagulation.
This is not an intervention or treatment study. It is an observational qualitative data study about tailoring a mindfulness intervention to assist families managing chronic health conditions.
This study is a randomized, open-label, two periods, cross-over pharmacokinetic, safety, tolerability and relative bioavailability of gepotidacin in healthy adult male and female participants of aged 18 to 50 years.
This VIDAS® NEPHROCLEAR™ CCL14 (VIDAS® NCL™ CCL14) Sample Stability clinical trial is a multicenter, prospective, and qualitative study. The main study objective is to determine sample stability conditions for the VIDAS® NEPHROCLEAR™ CCL14 Test. This test is intended to be used in conjunction with clinical evaluation in ICU patients with moderate to severe (stage 2 or 3) acute kidney injury (AKI) as an aid in the risk assessment for developing persistent severe AKI (stage 3 AKI lasting ≥ 72 hours) within 48 hours of patient assessment. The VIDAS® NEPHROCLEAR™ CCL14 Test is intended to be used in patients 21 years of age or older.
A study to determine the safety and efficacy of BXCL501 dosing for episodes of agitation associated with dementia when they occur (given as needed [PRN]), for a maximum of 28 doses within a 12-week treatment period.
In this research study the investigators aim to learn more about the therapeutic effects of a newer form of non-invasive transcranial magnetic stimulation (TMS), called theta burst simulation (TBS), on refractory depression in Autism Spectrum Conditions.
This double-blind, randomized, controlled, single-center clinical trial was conducted to assess the efficacy and tolerance of an anti-aging serum to improve moderate overall photodamage and skin fatigue of aging skin after 7 days of twice-daily use when compared to the efficacy of a combination of anti-aging serum and an anti-aging facial moisturizer. A total of 26 female subjects, aged 34-60, completed study participation.
