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 purpose of this study is to evaluate the efficacy and safety of KH001 in subjects with dentin hypersensitivity.
The goal of this interventional study is to determine the amount of skin C. acnes reduction with increased pressure during the chlorhexidine gluconate, brand name ChloraPrep, application. The main question it aims to answer is: Does changing the pressure applied during the ChloraPrep application impact the amount of C. acnes bacteria on the skin after one hour? Researchers will compare ChloraPrep applied at a pressure similar to a gentle wipe to ChloraPrep applied at a pressure similar to a massage to see if wash the amount of C. acnes on the skin after one hour is different. Participants will have one shoulder washed with ChloraPrep using pressure meant to impact the dermal layer, similar to a gentle wipe, and the other shoulder washed with ChloraPrep using pressure meant to impact the subdermal layer, similar to a massage. Participants will have swabs taken of their skin before the ChloraPrep application and again one hour after application to look for the amount of C. acnes on the skin.
This is a Phase 1 study to determine the safety and efficacy of allogeneic neonatal mesenchymal stromal cells (nMSCs) for the treatment of Dilated Cardiomyopathy. The purpose of the study is to help doctors and scientists learn if allogeneic neonatal mesenchymal stromal cells (nMSCs) infusions are a safe and effective way to improve cardiac function and left ventricular ejection fraction.
Participants will be recruited to complete self reported surveys normally used as standards of care for screening and monitoring depression and anxiety symptom severity, provide a voice sample composed of an answer to open ended questions and then be assessed by a mental health professional using structured and clinically validated assessment tools for depression and anxiety. Their voice will be analyzed by machine learning models that predict the severity of depression and anxiety symptoms. The models' performance will be compared to the clinician assessments and how that correlation compares to a similar comparison between the clinician assessments with the self reported surveys. It is hypothesized that the performance of the machine learning models in assessing the severity of depression and anxiety symptoms is no worse than the self reported surveys when both are compared to clinician assessments. It is also hypothesized that presence or absence of the diagnoses of Major Depressive Disorder and Generalized Anxiety Disorder can be predicted better than chance by the analysis of the participant's voice sample using machine learning models.
This study will address the following aims: Aim 1: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on body adiposity in adolescents with obesity. Aim 1a (Primary): Evaluate intervention effectiveness on total fat mass following the 8-week intervention. Hypothesis 1a: Adolescents randomized to the whole foods intervention will have lower total fat mass (kg) at the 8-week follow-up than those in the control group. Aim 1b: Evaluate intervention effectiveness on anthropometric changes following the 8-week intervention. Hypothesis 1b: Adolescents randomized to the whole foods intervention will have lower weight, BMI-z scores and/or waist circumference at the 8-week follow-up than those in the control group. Secondary Aims: Aim 2: Conduct an 8-week pilot RCT to examine the effects of a whole foods diet intervention on diet quality in adolescent and parent pairs during the study period. Hypothesis 2: Adolescents and parents randomized to the whole foods intervention will have higher diet quality scores at the 8-week follow-up than those in the control group. Aim 3: Conduct post-intervention family focus groups to identify how individual/family needs and preferences and social determinants of health (SDOH) may be perceived barriers and/or facilitators of diet adherence to a whole foods diet pattern.
The goal of this clinical trial is to explore the effects of virtual reality use on maximal aerobic exercise test performance (aerobic capacity) in healthy adults. The main questions it aims to answer are: - Does using a virtual reality program during a maximal aerobic exercise test lead to differences in VO2peak (maximal aerobic capacity)? and, - Does using a virtual reality program during a maximal aerobic exercise test lead to differences in work rate at the ventilatory threshold? Participants will complete a maximal aerobic exercise test two times (separated by 1 week of recovery) under the following conditions: - normal testing conditions in a lab - while viewing a virtual reality video Researchers will compare the test results of both conditions to see if the use of a virtual reality program alters VO2peak or the ventilatory threshold.
In previous clinical trial work, the investigators observed lasting reductions in headache burden after limited dosing of psilocybin. This purpose of this study is to examine potential sources for this observed effect. This study will measure brain resting state functional connectivity (fMRI), central synaptic density (SV2A PET), peripheral markers of inflammation, circadian rhythm (actigraphy), and sleep (sleep EEG) in both migraine and healthy control participants before and one week after the administration of psilocybin or an active control agent.
The purposes of this multicenter retrospective cohort study are to determine the residual nodal burden in patients with isolated tumor cells detected in the SLN or the clipped node after NAC and to determine oncologic outcomes in this group of patients after ALND or nodal RT or observation.
Ventricular tachycardia (VT) is a leading cause of death and suffering in the Veteran population. Currently, ablation procedures are performed to destroy the diseased tissue that causes this problem. This study will test to see if a new non-invasive targeting tool can help guide doctors during the procedure and improve the outcomes of the ablation procedure. Once this study is completed, the investigators will know whether this tool could help increase the efficacy, safety and accuracy of ablation therapy of fatal heart rhythms.
All patients will be provided with a Preprogen Pad to be worn for 4-6 hours to collect cells shed by the endometrium. After the kit is returned to the Preprogen laboratory, a brief survey will be completed. Analysis will be conducted to determine if the PadKitâ„¢ can collect a sample of endometrial cells sufficient to differentiate between normal and atypical hyperplasia/malignant cells in blinded samples provided to the laboratory for analysis.
