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 study intends to investigate the personal experiences of lymphedema patients who take part in a separate clinical trial including a specific medication intervention. The major focus will be on closely following individuals' rates of trial completion and withdrawal. The data collected from this study will help improve future outcomes for all lymphedema patients as well as those in under-represented demographic groups.
The study seeks to delve into the firsthand experiences of patients diagnosed with schizophrenia who partake in a separate clinical trial featuring a specific medical intervention. The primary emphasis will be on meticulously tracking the rates of trial completion and withdrawal among these individuals. The data collected from this study will help improve future outcomes for all schizophrenia patients as well as those in under-represented demographic groups.
Participants are being asked to participate in this research study because they have elected to undergo periacetabular osteotomy (PAO). This research study is looking at if using IV magnesium during surgery can help to reduce pain after surgery.
Influenza virus is a significant pathogen in pediatric solid organ transplant (SOT) recipients. However, these individuals respond poorly to standard-dose (SD) inactivated influenza vaccine (IIV). Recent studies have investigated two strategies to overcome poor immune responses in SOT recipients: (1) administration of high-dose (HD)-IIV compared to SD-IIV and (2) two doses of SD-IIV compared to one dose of SD-IIV in the same influenza season. One study compared HD-IIV vs. SD-IIV in adult SOT recipients and noted that HD-IIV was safe and more immunogenic; however, the median post-transplant period was 38 months. A phase I pediatric study comparing a single dose of HD-IIV vs. SD-IIV was safe with higher immunogenicity, but the study was limited by small sample size and median post-transplant vaccine administration was 26 months. In another phase II trial of adult SOT recipients, two doses of SD-IIV one month apart compared to one-dose of SD-IIV revealed modestly increased immunogenicity when given at a median of 18 months post-transplant. Therefore, these studies lack both evaluation in the early post-transplant period and substantive pediatric populations. Additionally, the administration of two-doses of HD-IIV in the same influenza season has not been evaluated in pediatric SOT recipients. Thus, the optimal immunization strategy for pediatric SOT recipients less than 24 months post-transplant is unknown. In addition, immunologic predictors and correlates of influenza vaccine immunogenicity in pediatric SOT recipients have not been well-defined. The central hypothesis of our proposal is that pediatric SOT recipients 1-23 months post-transplant who receive two doses of HD-quadrivalent inactivated influenza vaccine (QIV) will have similar safety but higher Hemagglutination Inhibition (HAI) geometric mean titers (GMTs) to influenza antigens compared to pediatric SOT recipients receiving two doses of SD-QIV.
This study will experimentally assess the comparability of in-lab and remote procedures with hypothetical and real ETM purchase outcomes.
This is single-center cross-sectional mechanistic study in lean and obese children with moderate-severe asthma, followed by a randomized, SHAM-controlled trial of Inspiratory Training (IT). The primary outcome is to describe the contributions of inspiratory muscle dysfunction (IMD) and Small Airway Dysfunction (SAD) to obesity-related versus non-obesity-related asthma. The study will involve training (IT) for 8 weeks at three intensity levels (SHAM, low and high). Target dose: 150 inspirations three times weekly. The population includes 6 to 17-year-old children with moderate to severe asthma and with a body mass index qualifying as normal habitus (BMI 5th to 84th CDC percentile) or obese habitus (≥95th percentile BMI and less than 170% of the 95th CDC percentile). Participants will be involved for 10 weeks. The investigators will use analysis of covariance (ANCOVA) to estimate and test the difference in mean values of baseline measures between obese and non-obese cohorts. Covariates will include age, sex (male/female), race/ethnicity, baseline asthma severity (NAEPP step 2 vs ≥3), and atopy status
Current therapies available for obstructive sleep apnea (OSA) have varying degrees of efficacy due to the complex nature of the disorder. A reduction in pharyngeal muscle activity characterizes OSA, and recent research has shown that combining atomoxetine and oxybutynin improves OSA severity. Thus this may be a viable treatment option. However, the specific effects of these agents alone and in combination on pharyngeal muscle activity remain unknown. The current study will look at the impact of each drug on pharyngeal muscles to gain insight into the mechanisms of this combination.
Concurrent electroencephalography (EEG) and new tripolar EEG (tEEG) will be recorded from adult and pediatric patients. In some patients stereo EEG (sEEG) will also be recorded concurrently.
The goal of this clinical trial is to investigate the effects of non-invasive transcutaneous auricular vagus nerve stimulation (taVNS) in patients with persistent atrial fibrillation. taVNS is a treatment through which a small electrical current is applied to a specific location of the left ear. The main question to answer is whether taVNS will reduce the heart rate in patients with persistent atrial fibrillation. After appropriate training, participants will self-administer taVNS for 30 minutes every day for two weeks. During one of the two weeks (randomized order), the clip electrode, delivering the electrical current will be attached to the cymba conchae of the left ear, while during the other week the clip electrode will be attached to the lobule of the left ear. During both weeks, the electrocardiogram (ECG) will be monitored continuously through a small ECG patch that is placed on the chest. Participants will meet with the investigators at the beginning of the study, after 7 days and at the end of the study (after 14 days). Researchers will compare the ECG obtained during the two weeks and evaluate if the heart rate differs between the two study weeks.
This is a phase I/II, open-label, multicenter study . During the study, subjects will be evaluated for safety, toxicity, tolerability, PK/PD, immunogenicity, biomarkers, and antitumor activity of HB0045. The phase I study will enroll up to 54 subjects with advanced solid tumors who have progressed on or after standard of care therapy and for whom there is no further treatment available that in the judgement of the patient's physician would be beneficial. One cycle is defined as 21 days.
