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.
Vaccine responses in patients treated with anti-CD20 antibodies (ocrelizumab and ofatumumab) or S1P receptor modulators (fingolimod and siponimod) were evaluated before and after third SARS-CoV-2 vaccination as part of an ongoing longitudinal study. Total spike protein and spike receptor binding domain (RBD)-specific immunoglobulin G (IgG) responses were measured by Luminex bead-based assay. Spike-specific CD4+ and CD8+ T cell responses were measured by activation-induced marker expression.
The goal of this observational study is to determine if intranasal lavage reduces symptoms in adults with COVID-19. The main question is can a hypochlorous acid solution reduce the symptoms of COVID-19. Participants will asked to do the following: - Irrigate each nostril once a day for ten days with a hypochlorous acid solution. - Write a daily record of the presence or absence of symptoms such as fever, headache, chills, nausea, or change in sense of smell. - After ten days, return the daily log in the mail to the investigator.
Expressive writing and motivational interviewing are well-known approaches to help patients handle stressful life events. While these methods are often applied by human counselors, it is less well understood if an automated approach can encourage behavior changes in patients. This study presents an automated writing system and evaluates its impact on individual behavior related to the COVID-19 pandemic. The investigators developed a rule-based dialogue system for "Expressive Interviewing" to elicit writing from participants on the subject of how COVID-19 has impacted their lives. In May-June 2021, the investigators randomly assigned online participants (N=151) to the Expressive Interviewing task and a control condition. The investigators examined their behavior with a survey before the intervention, immediately after, and two weeks after. In aggregate, task participants experienced a significant decrease in stress in the short-term (~23% decrease, p < 0.001) and no significant changes in longer-term outcomes compared to the control group. Within the task, participants showed different outcomes based on their writing. Participants who wrote with more anxiety-related words showed a greater short-term decrease in stress (R=-0.264, p<0.001), and those who wrote with more positive emotion words reported a more meaningful experience (R=0.243, p=0.001). For longer-term effects, participants who wrote with more lexical diversity underwent an increase in social activity (R=0.266, p<0.001). Expressive Interviewing can generally help with mental health in the short term but not longer-term, and participants' writing choices may make a difference in outcomes. While there were no significant long-term effects observed, the positive short term effect points to potential future directions with a series of Expressive Interviewing interventions for longer-term effects.
The purpose of this multicenter study is to assess the impact of SSO2 treatment on clinical outcomes and left ventricular function in patients following acute ST-segment elevation myocardial infarction (STEMI).
The primary objective of this study is to collect CT scan data without ECG-leads attached to the human subject. This data is intended to represent a typical range of clinical scenarios in which Cardiac CT imaging is used.
The current laboratory study examines e-cigarette preferences and smoking behaviors in menthol cigarette smokers.
This is a prospective, single-blinded, randomized study to assess the ability of taping methods used to secure intravenous (IV) catheters to resist the IV from being pulled away from the skin. Participants will have IV catheters taped on top of the skin (without insertion into the skin) using three taping methods, BCH Emergency Department (BCH ED), Chevron, and our novel method. Six measurements will be obtained per subject (3 random taping methods measuring their resistance to force in two directions, retrograde direction or towards the wrist and 90-degree angle to the arm).
This study explores user satisfaction with the BUILD mobile application.
This project tests the feasibility and preliminary proof of concept for a mindfulness-enhanced adaptation of Pivotal Response Treatment on parenting stress and child communication, using a randomized controlled design.
The purpose of this clinical trial is to learn about the pharmacokinetics and safety of a drug called zavegepant from samples collected using a patient-centric device called Tasso-Plus (for liquid blood sample collection) and Tasso-M20 (for dried blood sample collection) compared to standard venous sample collection. This study consists of two periods and will enroll approximately 14 healthy participants. In period 1, half of the enrolled participants (n=7) will use Tasso-Plus, and the other 50% (n=7) will use Tasso-M20. For each participant, PK samples will be collected after zavegepant administration in period 1 using the assigned Tasso device simultaneously with collecting venous blood samples. In addition, taste assessments will be performed at time intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant IN administration. Also, if feasible, 4 Japanese participants will be enrolled among those 14 participants to evaluate the PK and safety of zavegepant IN in Japanese vs. non Japanese participants. In period 2, a butterscotch candy will be given 5 minutes before administering the zavegepant IN study intervention. Taste assessment will also be performed after zavegepant IN administration with a butterscotch candy in period 2. For taste assessment, each participant will record the sensory attributes at timed intervals of 1 (immediately after dosing), 5, 10 and 20 minutes after zavegepant administration in each period. The expected duration of participation from screening until follow-up telephone contact is approximately 9 weeks.
