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 randomized crossover trial is determine whether acute consumption of blueberries with different proteins from plants (hemp or pea) or dairy (whey) impact the absorption of blueberry phytochemicals, which could impact the health benefits of blueberries. A secondary purpose is to understand the role that the gut microbiome may play, as well as the impact on urine polyphenol metabolites and potential implications for cardiometabolic health. Researchers will compare four arms: 1) Blueberries; 2) Blueberries + whey protein; 3) Blueberries + pea protein; and 4) Blueberries + hemp protein.
The goal of this clinical trial is to determine how changes in exercise and psychosocial stress may influence the risk of menstrual cycle irregularities in female runners and cyclists. The main questions it aims to answer are: - Does the implementation of exercise or psychosocial stress effect circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length? - Is there an additive effect of combined exercise and psychosocial on circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length? Participants will be asked to do the following over the ~3 month enrollment period: - attend a laboratory visit at the beginning and end of the study to have their resting metabolic rate, aerobic fitness, and body composition tested - monitor their menstrual cycle length, daily perceived stress levels, physical activity, and diet each month - provide several urine and saliva samples each month - either maintain their usual physical activity and lifestyle habits (control group), increase the duration of their weekly running or cycling mileage by 30% (exercise stress group), complete cognitive function tasks designed to be stressful (psychosocial stress group), or increase the duration of their weekly running or cycling mileage by 30% and complete cognitive function tasks designed to be stressful (exercise + psychosocial stress group) during the final month of enrollment. Researchers will compare control, exercise stress, psychosocial stress, and exercise + psychosocial stress groups to see if there is an effect on circulating reproductive hormones (i.e., estradiol, progesterone, luteinizing hormone) and menstrual cycle length.
The purpose of the D4325C00007 study is to identify and characterise patients with known or newly diagnosed CKD for possible participation in future renal clinical studies and to obtain an overview on current treatment choices for this patient group in different regions.
The purpose is to conduct a dietary intervention study in which human participants will consume beverages sweetened with erythritol or aspartame, each for 2 weeks, in a randomized crossover design
The purpose of this study is to evaluate the safety and efficacy of zipalertinib in patients with locally advanced or metastatic NSCLC harboring EGFR ex20ins mutations and other mutations.
Teleconsultation, or the use of video telecommunications technology to deliver expert recommendations for care remotely, has been used to improve the safety and quality of emergency care for children in hospital-based acute care settings by providing real-time access to remote pediatric physician experts. Whether extending teleconsultation as a patient safety intervention to emergency medical systems (EMS) outside hospitals can similarly benefit sick and injured children in the community is unknown. Advances in mobile technology have made teleconsultation more accessible and affordable for EMS systems. However, this intervention has been underutilized by EMS partially due to the lack of prehospital research supporting its efficacy for pediatric applications. In prior simulation studies, the investigators found high intervention acceptance among key stakeholder groups (pediatric emergency physicians and paramedics), and demonstrated that it was feasible to integrate video communication into prehospital clinical workflows involving critical care delivery in high-risk pediatric scenarios. These initial simulation studies were conducted in a controlled prehospital setting in static ambulances using infant simulator manikins to minimize risk to children and providers. Demonstrating feasibility and acceptability with real children in moving ambulances is the next step to build the necessary evidence base to support future planned prehospital efficacy trials with children. The investigators hypothesize that remote respiratory assessment of children by medical control physicians (expert physicians) using a mobile teleconsultation platform is acceptable to users (physicians and transport providers), and technically feasible in real transports.
The purpose of this study is to understand e-cigarette use and interest in quitting by exploring e vaping behaviors among a cohort of AYA survivors (N=500). The investigators will also examine demographic, medical, and psychosocial factors associated with vaping behaviors. Primary Objectives: Phase 1. - Objective 1. Identify characteristics of adolescent and young adult childhood cancer survivors (AYA CCS) nicotine vaping behaviors (e.g., e-cigarette use, interest in quitting, and quit attempts) and associations with demographic (e.g., sex, race, socioeconomic status, LGBTQ+ identification), cancer-specific (e.g., diagnosis, treatment factors), and psychosocial and behavioral factors. - Objective 2. Develop strategies to improve implementation of an evidence-based, mHealth vaping cessation program within an AYA oncology clinic. - Objective 2a: Use qualitative interviews to explore patient preferences regarding program implementation (e.g., timing of assessment of vaping behavior, confidentiality, referral approach) and identify barriers to uptake. - Objective 2b: Interview and/or ask healthcare providers (e.g., practitioners, advanced practice providers, social workers practicing in AYA oncology settings) to complete open- ended questionnaires related to current processes (e.g., workflow), needs, and barriers for assessing e-cigarette use and vaping cessation referral processes. Evaluate healthcare providers' information needs, preferences, and tools needed for integrating e- cigarette assessment and cessation program referrals into current practice. Phase 2. - Objective 3. Develop and test vaping assessment and referral implementation processes (developed from Objectives 1 & 2)., and uptake of an established mHealth vaping cessation program - Objective 3a: Using qualitative and quantitative measures, we will assess the reach (% of eligible AYA CCS that enrolled in mHealth program), adoption (% providers making referrals), strategy potential (provider/patient perceptions of referral process; appropriateness of program for patients), and maintenance (barriers/facilitators to implementation) of the program.
This phase I clinical trial tests the immune effects of fermented wheat germ in patients with advanced solid tumor cancers who are being treated with standard of care checkpoint inhibitors. Fermented wheat germ is a nutritional supplement that some claim is a "dietary food for special medical purposes for cancer patients" to support them in treatment. There have also been claims that fermented wheat germ is "clinically proven" and "recognized by medical experts" to "enhance oncological treatment" and boost immune response to cancer; however, there are currently no documented therapeutic effects of fermented wheat germ as a nutritional supplement. Checkpoint inhibitors, given as part of standard of care for advanced solid tumors, are a type of immunotherapy that may help the body's immune system attack the cancer and may interfere with the ability of tumor cells to grow and spread. The information gained from this trial may allow researchers to determine if there is any value of giving fermented wheat germ with standard of care checkpoint inhibitors for patients with advanced solid tumor malignancies.
The study seeks to delve into the firsthand experiences of patients diagnosed with chronic fatigue syndrome 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 chronic fatigue syndrome patients as well as those in under-represented demographic groups.
Taking part in clinical trials usually favors a particular demographic group. But there is limited research available to explain what trial attributes affect the completion of these specific demographic groups. This research will admit a wide range of data on the clinical study experience of neuroendocrine tumor patients to determine which factors prevail in limiting a patient's ability to join or finish a trial. It will also try to analyze data from the perspective of different demographic groups to check for recurring trends which might yield insights for the sake of future patients with neuroendocrine tumor.
