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 study is being done to assess the safety and efficacy of using mobile application-based Bristol stool scale to titrate lactulose in prevention episodes of hepatic encephalopathy.
Opioid medications are widely used after many orthopedic procedures and are routinely prescribed after shoulder replacement surgery. Despite the high prevalence of opioid abuse and misuse, there is no standardized mechanism for patients to dispose of unused opioid medications safely and securely and the average number of opioid pills required after shoulder replacement surgery is still unknown. In a prior pilot study conducted by our group (IRB# 202012142), opioid consumption patterns of patients undergoing shoulder arthroplasty were analyzed, as well as their adherence to a safe and secure disposal mechanism for excess opioid pills. A 94% retention rate was achieved and preliminary results showed that most of the subjects were 60 years of age and older. The objective of the current proposal is to: (1) develop pre-operative education materials related to post-operative opioid use following shoulder arthroplasty; (2) pilot the impact of this educational intervention; (3) examine the effect of providing disposal mechanisms for unused opioid pain medications following shoulder arthroplasty. The proposal is to conduct a single blinded randomized controlled trial of patients undergoing total shoulder replacement, both anatomic total shoulder arthroplasty (TSA) and reverse shoulder arthroplasty (RSA), and Hemiarthroplasty at UIHC. This randomized controlled trial will compare: (1) education plus opioid disposal to the standard of care (SC). The investigators hypothesize that pre-operative opioid education modules combined with a structured opioid disposal program will decrease opioid consumption following shoulder arthroplasty.
The purpose of this study is to estimate the relative bioavailability of nirmatrelvir/ritonavir of 4 different FDC tablet formulations relative to the commercial tablet formulation under fasted conditions in healthy adult participants.
This is a national-level research study of urologists. The purpose of this study is to assess the clinical evaluation and management (drug, procedures, counseling and other) of a subset of common patient care indications.
This is a randomized, placebo-controlled interventional study. The main purpose of this research is to test the safety and measure the immune response of the trivalent vaccine against invasive Salmonella disease. The vaccine will be tested over a range of doses.
This trial is taking place in Los Angeles, CA at clinics within the UCLA Health System. The study design is a 2x2 nested factorial design. Patients will be randomized into 1) receiving text based reminder messages with direct scheduling link, 2) portal-based reminder messages with direct scheduling link, or 3) the control group. Patients randomized to the intervention arms will receive reminders if they are due for influenza vaccine. Nested within the portal reminder arm, we will have two additional components for which patients will be randomized separately: 1. A pre-commitment prompt, asking patients which time (September, October, November or December) and which place (UCLA, pharmacy, workplace or school, or other) they plan to get their Influenza vaccine with tailored monthly messages based on responses (pre-commitment message with tailored recall messages with direct scheduling vs. standard portal reminders with direct scheduling). 2. A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination) Nested within the text message reminder arm, we will have one additional component for which patients will be randomized separately: 1) A pre-appointment reminder encouraging patients to ask for their influenza vaccine at their upcoming appointment (pre-appointment reminder encouraging influenza vaccination vs. standard pre-appointment reminder not mentioning influenza vaccination) Despite the Advisory Committee on Immunization Practices (ACIP) recommendation in 2010 that all people above 6 months of age should receive an annual flu vaccine, vaccination rates remain low: at 6m-4.9 yrs. (70%), 5-17.9 yrs. (56%), 18-64.9 yrs. (38%), and >65 yrs. (63%). The investigators will assess the effectiveness of MyChart R/R messages and text R/R messages as compared to the standard of care control (no messages).
Multi-center, randomized, double-blind, vehicle-controlled, parallel group, dose escalation study of TDM-180935 following topical administration in healthy male subjects, 18 to 55 years old
The primary purpose of this study is to compare immediate changes in pain sensitivity (pressure pain threshold) during quiet rest, low fatigue exercise, and high fatigue exercise.
The primary aims of this study are to assess the feasibility, acceptability, and tolerability of using an immersive extended reality (XR) headset to engage in behavioral activation (BA) for individuals diagnosed with major depressive disorder (MDD). The secondary aim of this study is to explore the efficacy of using XR to enhance BA therapy in a clinical MDD population.
The majority of smokers try to quit each year, and the majority of quit attempts fail, even when the most effective FDA-approved pharmacotherapies are used. Non-combustible tobacco products emit fewer harmful chemicals than cigarettes, and thus for smokers who cannot quit smoking, switching completely to a less harmful product is likely to improve their risk of cancer and other deleterious health outcomes. E-cigarettes, the most commonly used non-cigarette tobacco product, have been shown to deliver sufficient nicotine, be appealing to smokers, and reduce cigarette smoking when provided to smokers to use ad libitum. For smokers who have failed to quit with traditional methods, trying to switch to a less harmful product may be more likely to help them stop smoking than trying to quit using tobacco altogether repeatedly with pharmacotherapy. The proposed trial evaluates the potential of e-cigarettes to serve as harm reduction tools for current smokers who have already tried, and failed, to quit with traditional methods. Current smokers who failed to quit with FDA-approved pharmacotherapy within the past year (N=30) will be randomly assigned to either 1) switch completely to e-cigarettes (Switch Group, n=20), or 2) try to quit again using pharmacotherapy (Meds Group, n=10). Thus, our design is strengthened by a strong active control group. Participants will select a Target Switch / Quit Date on which they will stop smoking. Participants in the Switch group will receive a 5-week supply of JUUL e-cigarettes, the most popular e-cigarette currently available. Participants in the Meds Group will receive a 5-week supply of combination nicotine replacement therapy (transdermal nicotine patch and short-acting nicotine lozenge). Participants will use 1-week of their tobacco product or medication ad libitum while continuing to smoke in advance of their Target Switch / Quit Date, and 4-weeks as instructed following a Target Switch or Quit Date. Behavioral outcomes of interest include smoking reduction > 50% and biochemically-confirmed abstinence from cigarette smoking at 4-weeks. The proposed trial addresses a highly significant research question using a rigorous design and is supported by a strong investigative team.
