73 Clinical Trials for Various Conditions
This study recruit individuals who are 18 years of age AND Do NOT have a history of diagnosed anxiety disorders AND Do NOT currently have any area of pain lasting 3 months or longer. The study will measure discomfort with a controlled application of pressure to different muscles and compare these measures with the individual's score on a standardized assessment of anxiety.
This is a prospective study to establish the analytical specificity of Bladder EpiCheck test in urine samples from healthy population and urology patients without prior history or evidence of bladder cancer.
The goal of this interventional study is to test the effects of trigger point dry needling to the low back in a healthy population. The main aims are to answer: * Is there a change in sensitivity to experimental pain after trigger point dry needling * To determine if there is an association between demographic and psychological factors and immediate changes in pain sensitivity after receiving trigger point dry needling. Participants will be randomly assigned to one of two groups a dry needling group or a sham dry needling group. The dry needling group will receive trigger point dry needling to the lumbar spine. The sham dry needling group will receive needling to the lumbar spine with a sham needle which does not penetrate the skin. In other words, researchers will compare an intervention group and a sham group to see if dry needling has an immediate change in pain sensitivity in response to experimentally induced pain.
This study focused on improving breathing mechanics by using various osteopathic manipulative therapy (OMT) techniques. The investigators randomly assigned participants to a control group who received sham treatment and a treatment group who received OMT. The investigators measured variable pre- and post- treatment on both groups. The investigators observed an improvement in breathing mechanics in the treatment group.
This is a randomized, double-blind, placebo-controlled, crossover study designed to investigate the safety and efficacy of Qualia Mind on cognition in a healthy adult population between ages of 18 and 75 years. Qualia Mind is a nootropic supplement containing a complex mixture of vitamins, minerals, amino acids, choline donors, and herbal ingredients. These components have been demonstrated to exert their cognitive effects through distinct mechanisms of action involving cholinergic, glutamatergic, and dopaminergic receptor signalling; neuroplasticity; and modulation of cell membrane structure and metabolism.
The objective of this study is to determine the effects of consuming either 3 eggs per day as compared to a daily choline supplement (choline bitartrate, 397.5 mg choline/day) on plasma concentrations of High Density Lipoprotein-cholesterol (HDL-C), trimethylamine N-oxide (TMAO), and other biomarkers of cardiovascular disease risk in young, healthy individuals. The goal is to determine if choline given as phosphatidylcholine (eggs) will lead to a different TMAO response when compared to choline in free supplemental form.
The purpose of this study is to investigate the effects of OPTI-BIOME™ (Bacillus subtilis MB40), a probiotic supplement, on bloating, gas and abdominal discomfort symptoms in otherwise healthy adults.
This study is to investigate the effects of controlled whole-body vibration training on reducing the likelihood of falls among healthy population and people with multiple sclerosis. (NOTE: research not covered by sponsored funding)
Recently, the United States Department of Agriculture (USDA) has recommended removal of the 300mg/day limit on dietary cholesterol intake due to a lack of evidence supporting a connection between cholesterol intake and increased risk for cardiovascular disease (CVD). Previous work has shown that daily intake of eggs actually favorably alters many parameters associated with CVD risk. Conversely, emerging research suggests that choline, a nutrient in eggs, may be converted into trimethylamine oxide (TMAO) by the intestinal microbiota. TMAO is thought to increase the risk for CVD. Therefore, the purpose of this study is to determine a threshold of daily egg intake at which the risk for CVD is not negatively impacted in a young, healthy population.
The purpose of this study is to determine if aspirin is associated with bleeding complications following a single tooth extraction
The aim of the current study is to replicate the COXA-0508-258 study in a multicenter, US setting, using a lower dose of ASA. It is expected that this study will not only confirm the results of the 258 study but show that the incidence of UGI ulcers on celecoxib is significantly less than on traditional NSAIDs and the incidence of UGI ulcers on celecoxib increases with the addition of ASA, but still is lower than traditional NSAIDs plus/minus ASA. This 7-day study is designed to compare the incidence of gastroduodenal ulcers associated with celecoxib 200 mg QD and low dose aspirin 81 mg QD and with naproxen 500 mg BID plus low dose aspirin 81 mg QD in healthy adults(50-75 years of age).
This study aims to evaluate whether an objective, data-driven bike fitting using the id match 3D motion capture system improves power output in recreational cyclists. Participants will complete two cycling performance tests, a 6-second Wingate Anaerobic Test (PPT6) and a 20-minute Functional Threshold Power (FTP) test, before and after receiving a professional bike fitting. The primary outcome is the change in power output on both tests. Secondary outcomes include subjective measures of comfort, pain, and perceived exertion. The goal is to determine whether bike fitting alone, independent of training, can enhance both performance and the overall riding experience.
This study is designed to evaluate the performance of the Verily Clinical Study Watch for the quantification of participants' movement and pulse rate when the wearer is at rest.
This study is a randomized, double-blind, crossover trial aiming at evaluating the gastrointestinal tolerance of 3 sugar replacers mixes at 3 different doses. The investigators will also try to understand the factors that could explain the presence or absence of symptoms
The rationale for this study is to observe the effect of a consumer-grade commercially available product called Mimio Biomimetic Cell Care on metabolic health in overweight individuals. Additionally, the study aims to observe the effects of the study product on hunger and satiety, as well as effects on cognitive function, sleep, stress, pain, mood, gastrointestinal symptoms and metabolic and inflammatory blood markers via activities that can successfully and effectively be completed in a home setting. Because this product is currently available in the OTC market across the United States, a consumer-driven, decentralized observational clinical research study is well-suited for examining the effects of this study product in this population. The study will examine outcomes in a broad age range of adults who have chosen to try this product. The study will incorporate participant reported outcome questionnaires and surveys, blood sample collection for NMR lipoprofile, oxidized LDL, hsCRP, HbA1c, Insulin and plasma glucose and a saliva sample collection for biological age test. There is no "doctor-patient" relationship as part of this research since the participant as a consumer is making the informed choice to take the product and take part in the observational process with self-reported measures, saliva sample collection and blood sample collection at their local laboratory. Findings from this study will contribute knowledge toward the design of future studies and important knowledge on metabolic health.
This is a single center, prospective, biomarker-result-blinded observational study evaluating immunoassay measurements of pancreatic stone protein (PSP) performed on Abionic's abioSCOPE device with the PSP assay on generally healthy adults representative of the US population.
Background: Shingles is a painful, blistering rash caused by the same virus that causes chickenpox. Shingrix is a vaccine approved to prevent shingles in healthy adults over age 50 and in immunocompromised adults over age 18. Researchers want to learn more about how people with HIV respond to Shingrix. Objective: To learn how Shingrix affects the immune response in people with HIV. Eligibility: People aged 18 years and older with HIV. Healthy people aged 50 years or older are also needed. Design: Participants will have at least 4 clinic visits in 1 year. Participants will be screened. They will have a physical exam with blood and urine tests. At their first visit, participants will receive Shingrix as a shot in the upper arm. They will have a rectal swab; a cotton swab will be inserted into the rectum and rotated gently to collect bacteria. Participants will receive a second shot of Shingrix 2 months after the first one. They will visit the clinic again 3 and 12 months after the first shot. Participants will receive a 28-day memory tool. They will write down their symptoms between clinic visits. They will have up to 4 phone calls to talk about side effects of the shot. Participants may undergo apheresis: They will lie still while blood is drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in their other arm....
Background: During the first few decades of life, the brain changes dramatically in shape and function. Sleep lets researchers measure these changes. Researchers want to create a database of sleep and neurodevelopmental data in a group of infants and children to learn more. Objective: To address a knowledge and data gap in the field of sleep and neurodevelopment in infants and children. Eligibility: Children ages 6 months to 76 months who may or may not be at risk for neurodevelopmental and neuropsychiatric disorders. Also, children ages 6 months to 8 years who have a referral for a sleep study. Design: Participants will have neurodevelopmental testing. They will have a medical, psychiatric, and family history. They will have a physical and neurological exam. They will be interviewed and complete surveys. They will give a cheek swab and/or blood sample. Some participants will have 1 study visit that lasts 2 days. Other participants will have up to 4 study visits. Each visit will last 2 days. Visits occur every 8 months to 1 year, for a total participation time of 2 years. Participants will have a 20-minute daytime electroencephalogram (EEG), if possible. This EEG session will be used to calibrate the machine for the overnight study. Participants will take part in an inpatient overnight sleep study. Electrodes will be placed on the participants. For young children, parents will help place the EEG leads. Other sensors may also be placed. A gauze cap will be placed on participants head to protect the leads and keep the participants from moving them. 'Lights out' will occur as close to participants bedtime as possible.
The overall objective of this study is to explore whether transcranial Direct Current Stimulation (tDCS) can accelerate associative learning and boost associative memory in healthy subjects.
The purpose of this study is to evaluate the immunogenicity and safety profile of CSL425 (CSL's 2009 H1N1 influenza vaccine) in a healthy pediatric population.
The purpose of the study is to understand the relationship between what an individual inherited from their family (genetics), how they respond and feel after drinking alcohol, and how they respond to pre-treatment with naltrexone, a medication that blocks some of the effects of alcohol and is approved for the treatment of alcoholism. The investigators are conducting this study on those of African descent because there is almost no research focused on this group and the association with genetics. The investigators seek to enroll 40 people in the study. Participation will consist of 4 different alcohol challenge sessions in a cross over design. Each session will be separated by at least 10 days. In total, there will be four challenge sessions.
The purpose of this study is to compare Prilosec OTC® and Zegerid® in their effects on gastric acid suppression.
This is a Phase 1b, randomized, double-blind, dose-escalating, age de-escalating, placebo-controlled study of 200 children, ages 6 months to 17 years. This clinical trial is designed to assess the safety, tolerability/reactogenicity, and immunogenicity of one and two doses of Sing2016 M2SR H3N2 influenza vaccine (manufactured by FluGen) administered intranasally in seven cohorts of children. The study design includes pre-planned Safety Review Committee( SRC) reviews. The first two groups to be vaccinated will be Cohorts 1 and 2. Cohort 1 consists of 45 children 9-17 years old. Thirty of them will receive one dose of the vaccine at a dose of 10\^9 TCID50, and 15 will receive one dose of placebo. Cohort 2 comprises 45 children 2-8 years old. Thirty of them will receive one dose of the vaccine at a dose of 10\^8 TCID50 and 15 will receive one dose of placebo. Cohort 3 consists of 25 children 2-8 years old. 15 of them will receive one dose of vaccine at 10\^9 TCID50 and 10 will receive one dose of placebo. Once 25 participants in Cohort 3 have completed Day 8 of follow-up, similar to Cohorts 1 and 2, the SRC will review to ensure no halting rules are met and if no rules are met, and the SRC determines it is safe to proceed, simultaneous enrollment into Cohorts 4 and 5 can begin. If any halting rules are met or any concerns are raised by the SRC, an external SMC may meet to discuss the data for recommendations on either progression or clinical trial modification before progression to the next cohort. Cohort 4 consists of 25 children 2-8 years old; 15 of them will receive two doses of vaccine at 10\^9 TCID50 and 10 will receive two doses of placebo, with a 28-day interval between the first and second doses. Due to the limited availability of product, and funding to support additional years of enrollment into Cohorts 5, 6, and 7, the decision was made to stop enrollment after the final participant was enrolled into Cohort 4. The primary study objective is to assess the safety and tolerability of one and two administrations of the Sing2016 M2SR H3N2 influenza vaccine at 10\^8 or 10\^9 TCID50 delivered intranasally to healthy participants, 2 to 17 years of age.
The purpose of this study is to see how safe an investigational new drug (T89) is and how well healthy Japanese subjects tolerate it when given two single doses and a multiple dose.
The objective of this study is to compare Prilosec OTC® to Prevacid® for gastric acid suppression.
The reported normal values used in diagnosing and treating pediatric kidney stone formers are based on adult values or historic data from small studies. Urinary supersaturation indices which are now described in the adult stone literature as more sensitive predictors of stone composition, and precise predictors of response to therapy, are not established in children. The goals of this prospective study are to redefine normal values for pediatric urinary metabolites and supersaturation indices based on samples from a large number of healthy children and to identify if a difference in urinary supersaturations in children is protective.
This randomized, double-blinded, placebo-controlled Phase 3 study is designed to evaluate the safety, tolerability, and immunogenicity of 3 lots of RSVpreF in healthy adults.
To determine the functional effects of Citicoline, a natural supplement, when administered for a duration of four weeks (28 days) to non-psychiatric adolescent male participants. The investigators hypothesize that citicoline will provide cognitive benefits to this population after 28 days of supplementation.
The purpose of this study is to see how the body reacts to different strengths of the H1N1 flu shot when it is given with or without an "adjuvant." An adjuvant is a substance that may cause the body to produce more antibodies when it is given with a vaccine. This study will also compare how age affects the body's response to the H1N1 flu shot. In this study, 3 strengths of the H1N1 flu shot will be tested combined with an adjuvant. In addition, 2 strengths of the H1N1 flu shot will be tested without adjuvant. Two H1N1 flu shots of the same strength, with or without adjuvant, will be given about 3 weeks apart. Participants will include up to 800 healthy adults, approximately 500 individuals ages 18-64 and 250 individuals greater than or equal to age 65. Study procedures include: physical exam, blood samples, completing a memory aid to record vaccine side effects, medications and daily oral temperature. Participants will be involved in study related procedures for up to 13 months.
The clinical objective of this study is to quantify the levels of corneal and conjunctival staining in a healthy, non-dry eye population. This is a descriptive study without test article administered.
