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.
This project addresses Objective 2 of RFA-CE-21-002: to assess risk and protective factors for illicit stimulant use, use disorder, or overdose that can contribute to the development or adaptation of intervention strategies. The study will 1) develop and validate a model using both person-level and area-level characteristics to identify, among Medicaid enrollees age 15 and older, who is at highest risk of an inpatient hospitalization or emergency department (ED) encounter for overdose from cocaine or other stimulants; 2) develop and validate a model to identify, among those Medicaid enrollees age 15 and older at highest risk of an inpatient hospitalization or ED encounter for stimulant overdose, when they are at highest risk; and 3) among those Medicaid enrollees age 15 and above with a prior inpatient hospitalization or ED encounter for stimulant overdose, to measure the rate of and identify risk and protective factors for a subsequent inpatient hospitalization or ED encounter for overdose from stimulants and/or opioids.
This project will evaluate the effects of bilateral knee pain and dry needling (DN) on laterality recognition, movement and muscle function. The objective is to determine if laterality recognition accuracy deficits are present in individuals with bilateral chronic knee pain and if DN affects 'central' and 'peripheral' musculoskeletal measurements. Chronic musculoskeletal pain results in changes to the way the brain perceives pain and left-right discrimination between body parts. This phenomenon has been established for individuals with chronic back pain and chronic regional pain syndrome, but has not been described for individuals with bilateral knee pain without the presence of knee OA. Dry needling involves the insertion of a small diameter monofilament needle into muscle, and has been purported to affect the neuromuscular system both centrally and peripherally. Sixty individuals between 18 and 40 years old will be recruited and allocated into three groups. The first group will consist of 20 subjects presenting with bilateral chronic anterior knee pain and high fear of movement with scores on Tampa Kinesiophobia Scale (fear of movement) greater than 37. The second group with consist of 20 subjects with bilateral chronic anterior knee pain and low fear of movement between ages of 18 and 40 years old, and the third group will consist of healthy controls without knee pain between 18 and 40 years old. All subjects will undergo baseline testing consisting of laterality recognition, movement analysis, muscle force production, and ultrasound imaging. Subjects will undergo laterality recognition testing using the Neuro Orthopaedic Institute (NOI) Recognise Knee phone application. 2D video analysis of the lateral step down test will be performed followed by peak isometric force production assessment of knee extension and flexion. Muscle function of the vastus medialis will be measured with ultrasound imaging where cross-sectional area and other measurements (tendon length, muscle thickness, etc) will be captured with Lumify ultrasound imaging transducer. Then DN to the quadriceps will be performed. After DN procedure, subjects will undergo aforementioned measurements from baseline testing. Testing will require only one appointment by the subject, which will last approximately 2 hours an include baseline testing, dry needling, and post testing. No follow up will occur afterwards.
The purpose of this study is to assess the safety and immunogenicity of different formulations of monovalent Influenza A/Astrakhan/3212/2020-like virus vaccine with AS03 adjuvant system in adults greater than or equal to (>=)18 years of age.
This is a LTFU study for cervical SCI subjects that were administered AST-OPC1 cells in the main study AST-OPC1-01.
The purpose of this study is to evaluate the safety and immunogenicity in parallel of heptavalent mRNA-1975 and monovalent mRNA-1982 against Lyme disease in healthy adult participants.
The goal of this non-interventional, observational study is to learn if cortical plexus enhancement in patients with primary progressive multiple sclerosis occurs in response to the autoimmune inflammatory process.
The goal of this non-interventional, observational study is to determine whether cortical pathology can be slowed down by use of ocrelizumab.
The goal of this interventional study is to test the efficacy of combined mindfulness meditation training and cognitive training on brain function and cognition in healthy older adults. Participants will undergo cognitive and neuroimaging (MRI and fNIRS) assessments before and after an 8-week (~20 hours) training intervention. The intervention will consist of at-home mindfulness meditation followed by playing a cognitive game on a provided tablet. The findings will be compared to an existing data from older adults who trained on the cognitive game only (NCT03988829; Arms 1 and 2).
The goal of this prospective observational cohort study is to validate a previously developed pancreatic cancer risk prediction algorith (the PRISM model) using electronic health records from the general population. The main questions it aims to answer are: - Will a pancreatic cancer risk model, developed on routine EHR data, reliably and accurately predict pancreatic cancer in real-time? - What is the average time from model deployment and risk prediction, to the date of pancreatic cancer development and what is the stage of pancreatic cancer at diagnosis? The risk model will be deployed on data from individuals eligible for the study. Each individual will be assigned a risk score and tracked over time to assess the model's discriminatory performance and calibration.
This study is a large-scale investigation (Phase 3) into a new booster shot designed specifically for teenagers. The booster targets a particular variant of COVID-19, Omicron XBB.1.5. The main focus is on safety: researchers want to see if this new booster is safe for teenagers who have already received two doses of the Pfizer or Moderna mRNA COVID-19 vaccines. To ensure a fair comparison, the study will use a double-blind approach. This means two groups of teenagers will receive booster shots, but neither the teenagers nor the researchers giving the shots will know beforehand which version of the booster each person gets. The study will also assess how well the body fights the virus after the booster shot.
