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 goal of this clinical trial is to compare indoor air quality and health in people exposed to air pollution, including possible exposure to wildfire smoke. The study will test the effect of using a do-it-yourself (DIY) air cleaner when air pollution is present to answer the following questions: - Do health outcomes differ between participants who use a DIY PAC and those who use a sham air cleaner? - How effective is the DIY air cleaner in reducing indoor concentrations of fine particles (PM2.5), and volatile organic compounds found in wildfire smoke? OR How effective is the DIY air cleaner in reducing indoor concentrations of fine and coarse particles (i.e., PM 10)? - What are barriers to use of a DIY air cleaner and what factors facilitate its use? Participants will be asked to do the following: - Participate in 5 home visits from study staff between July - October 2023 - Have an air quality sensor placed in the participant's bedroom for the whole study period - Have a small sensor attached to the main door of the participant's house to record when the door is open or closed (important for air quality inside) - Allow researchers to take air and dust samples in the participant's bedroom - Run a DIY air cleaner in the participant's bedroom for at least 6 nights while the participant sleeps - Complete 2 interviews - Allow study staff to collect 3 fingerstick blood samples - Allow study staff to collect 3 samples of fluid from inside the nose - Use the study air cleaner in the participant's bedroom during the study period The investigators will measure air quality in participating homes and measure health outcomes for participants. The investigators will compare outcomes of participants who use a DIY air cleaner with filters that work well to those of participants who use a DIY air cleaner with a placebo filter (one that does not work well to remove the air pollutants of concern). The goal of the study is to see if using the effective air cleaner leads to better health outcomes and indoor air quality.
The goal of this multi-site observational cohort study is to link electronic health records (EHR) with novel data sources to examine insurance instability and its association with all-cause and overdose mortality in adult patients who received medications for opioid use disorder (MOUD). The main objectives of the study are: - Objective 1. Perform data linkage of a cohort of patients who received MOUD with the National Death Index using a probabilistic algorithm for matching records to ascertain fact and cause of death relative to treatment and insurance status. - Objective 2: Assess the association of insurance instability and risk of death, including all-cause mortality and drug- and alcohol-related overdose mortality.
Nerivio is a remote electrical neuromodulation (REN) device that is FDA-cleared for migraine prevention (as well as for acute treatment of migraine), in individuals 12 and older. The study is a post-marketing, observational, prospective, real-world evidence study assessing the safety, efficacy, and health economics outcomes of Nerivio for migraine prevention in a real-world environment. The study population is naïve Nerivio users, aged 12 and up, who were prescribed Nerivio by their healthcare provider for either prevention treatment (for use every other day) or dual-use treatment (for use every other day and upon the onset of a migraine). The study period per participant is six months. During this period, participants will be requested to use Nerivio according to the instructions of their healthcare provider and to fill out a short daily questionnaire in the Nerivio application
Cross-over arm of the pilot study evaluating a treatment for obesity.
Financial distress affects 30-70% of cancer patients and describes the burden that patients experience due to the costs of care (CoC). One reason may be because patients lack the appropriate information on CoC that would help them better plan for and manage their CoC. Therefore, the investigators plan to test a Proactive CoC intervention which includes a discussion with a trained educator on CoC information and a Cost Tracking tool to help patients deal with their CoC.
Mannooligosaccharides (MOS) derived from baker's yeast may have prebiotic properties such as improving gastrointestinal function. The aims of this study are to determine the effect of MOS on gastrointestinal function and symptoms and fecal microbiota in older adults.
Project PLUS is a pilot study that aims to develop and obtain preliminary feasibility and efficacy data on an enhanced risk communication approach to promote lung cancer screening (LCS) intentions among screening-eligible individuals from environmentally burdened communities. Project PLUS will combine qualitative interviews to explore subject awareness regarding lung cancer risk and air pollution, barriers to LCS, and perceptions regarding risk communication messaging, develop a health education video, and a between-subjects experiment to compare Data from this pilot will form the basis for enhanced community engagement efforts and subsequent communication research to examine the effectiveness of incorporating the involuntary air pollution risk information in risk communication interventions. The long term goal is to reduce lung cancer burden and disparities among environmentally burdened communities within and outside of Philadelphia.
This is a human subject research study conducted in patients undergoing dialysis treatment with darbepoetin alfa at Intermountain Utah Dialysis and Intermountain Medical Center Dialysis Services. The purpose is to test a dose recommendation algorithm that may reduce hemoglobin variability and drug cost.
Frailty is associated with higher rates of morbidity, mortality, and failure to rescue after major surgical procedures [1]. Sarcopenia is degenerative loss of skeletal muscle mass and strength. It is a key component of physical frailty and is associated with poorer post-surgical outcomes due to decreased patient strength and vitality.
Recent advances in technology have allowed for the detection of cell-free DNA (cfDNA). cfDNA is tumor DNA that can be found in the fluid that surrounds the brain and spinal cord (called cerebrospinal fluid or CSF) and in the blood of patients with brain tumors. The detection of cfDNA in blood and CSF is known as a "liquid biopsy" and is non-invasive, meaning it does not require a surgery or biopsy of tumor tissue. Multiple studies in other cancer types have shown that cfDNA can be used for diagnosis, to monitor disease response to treatment, and to understand the genetic changes that occur in brain tumors over time. Study doctors hope that by studying these tests in pediatric brain tumor patients, they will be able to use liquid biopsy in place of tests that have more risks for patients, like surgery. There is no treatment provided on this study. Patients who have CSF samples taken as part of regular care will be asked to provide extra samples for this study. The study doctor will collect a minimum of one extra tube of CSF (about 1 teaspoon or 5 mL) for this study. If the patients doctor thinks it is safe, up to 2 tubes of CSF (about 4 teaspoons or up to 20 mL) may be collected. CSF will be collected through the indwelling catheter device or through a needle inserted into the lower part of the patient's spine (known as a spinal tap or lumbar puncture). A required blood sample (about ½ a teaspoon or 2 3 mL) will be collected once at the start of the study. This sample will be used to help determine changes found in the CSF. Blood will be collected from the patient's central line or arm as a part of regular care. An optional tumor tissue if obtained within 8 weeks of CSF collection will be collected if available. Similarities between changes in the DNA of the tissue that has caused the tumor to form and grow with the cfDNA from CSF will be compared. This will help understand if CSF can be used instead of tumor tissue for diagnosis. Up to 300 people will take part in this study. This study will use genetic tests that may identify changes in the genes in the CSF. The report of the somatic mutations (the mutations that are found in the tumor only) will become part of the medical record. The results of the cfDNA sequencing will be shared with the patient. The study doctor will discuss what the results mean for the patient and patient's diagnosis and treatment. There will not be any germline sequencing results reported and these will not be disclosed to the patient, patient's clinician or be recorded in patient medical record. Patient may be monitored on this study for up to 5 years.
