99 Clinical Trials for Various Conditions
The purpose of this study is to learn about the experiences of cancer patients during treatment utilizing a mobile app called EveryDose© to track prescribed oral treatment for cancer. Based on these experiences, the study team will decide on expanding this pilot study to evaluate other methods that may prove to be beneficial in supporting cancer patient's ability to take cancer medications as prescribed (another common phrase used for this is adherence to treatment).
Cannabidiol (CBD), a non-psychoactive hemp derivative, is an attractive therapeutic target, and is most supported by the scientific community as an antiepileptic, anxiolytic, and antipsychotic. Additionally, CBD may cause alterations in aspects of health and fitness, fatigue, stress, calmness, quality of life, cognitive function, ability to maintain focus, sleep quantity, and sleep quality. Cannabidiol may be associated with alterations in inflammatory response in the human body, which has implications in both healthy and diseased populations. Natural killers cells (NKC) play a vital role in maintain your body's defenses and are an essential component of your immune system. In humans, NKC contain the highest concentrations of receptors associated with the endocannabinoid system and CBD. Human models have demonstrated that CBD use increases the percentage of NKC in peripheral blood. However, similar models found that CBD administration inhibits markers of NKC cytotoxic function, a beneficial cellular mechanism used to prevent malignant cell transformation and viral infection. The overarching goal of this investigation is to determine the effects of an 8-week CBD intervention on measures of fatigue, stress, calmness, quality of life, cognitive function, focus, health and fitness, and sleep quantity, and sleep quality. In addition, this study will explore a potential CBD mechanism of action with a focus on biomarkers of neural health, inflammation, liver health, kidney health, as well as NKC number and function.
Coronary artery disease (CAD) is a common disorder that can lead to heart failure. Not all people with CAD are eligible for today's standard treatments. One new treatment approach uses stem cells-specialized cells capable of developing into other types of cells-to stimulate growth of new blood vessels for the heart. This study will determine the safety and effectiveness of withdrawing stem cells from someone's bone marrow and injecting those cells into the person's heart as a way of treating people with CAD and heart failure.
AZUR Pharma has received several reports from practicing psychiatrists prescribing FazaClo showing that FazaClo patients start losing body weight instead of keep gaining it, after being switched from other clozapine products or other atypical antipsychotics treatments. Another important clinical observation reported by doctors is a considerable reduction in hypersalivation when FazaClo administration is compared to other antipsychotic treatments. Based on the findings described above, and on the real need for effective and safer treatments for schizophrenia, AZUR Pharma has decided to design and conduct an observational study in a large number of patients taking FazaClo to prove the received clinical reports from physicians. Better understanding and evaluation of these beneficial findings are necessary to provide physicians information for improved treatment decision.
Background: People who were born outside of the country are the largest group of adults infected with chronic hepatitis B virus (HBV) in the US. HBV affects the liver. If not treated, HBV infection can lead to serious liver disease, including cancer. One recent study showed that only 35% of foreign-born US adults were aware of their HBV infections. Foreign-born US adults may also have trouble getting proper care after they are diagnosed with HBV. In one small survey, language, cultural, and financial barriers were cited as the biggest reasons for not receiving care. To help more people with HBV, researchers want to learn how to find and overcome any barriers to care. Objective: This natural history study seeks to identify and better understand barriers that prevent foreign-born US adults from getting proper care for HBV infections. Eligibility: People aged 18 years and older with chronic HBV who were born outside of the US. Design: Participants will visit the NIH clinic 1 time. This visit will take about 20 minutes. Researchers will review participants medical records and collect information about their HBV. Participants will complete a survey. They will answer questions about: Where they came from. When they came to the US. How well they have adapted to living in the US. The health care they have received for HBV. Their age, gender, and education. Participants will be paid $10 for completing the survey.
This research intends to identify common smoking triggers and barriers to quitting smoking; understand useful and effective strategies for smoking cessation; and explore the feasibility and acceptability of mobile phone-based interventions among low-income smokers.
Patients who start home dialysis take on an added responsibility and that can be challenging. The investigators are interested in studying the patient and care partner perspective on the challenges that the participants faced on home dialysis and what interventions could help support them better by holding focus group discussions.
This clinical lactation study is to provide information regarding the PK and amount of OLZ/SAM in breast milk and estimated infant exposure.
The research team will conduct a multi-site, randomized controlled trial examining the effectiveness of exercise intensity progression compared to standard practice (no progression) in the context of swallowing rehabilitation. The study will also determine the impact of using biofeedback during resistance training on tongue strength. The study is a first step in determining an optimal delivery of tongue strengthening exercise in typically aging older persons, with the plan to develop a framework for guiding clinical practice of tongue strengthening in various dysphagic populations. Participants will be randomized into one of four treatment groups and complete 8 weeks of tongue resistance training.
The main purpose of this study is to evaluate a new type of gamma camera (the Veriton system) that provides a significant gain in system sensitivity and improved image quality compared to a conventional gamma camera that can achieve equal or better image quality than a standard SPECT/CT system.
Active males and females consumed a probiotic for 28-days. Before and after the intervention period, participants reported to the lab in a fasted state where they consumed 25 grams of whey protein. Following drink consumption, participants provided blood draws at 15-minute intervals. Blood samples were analyzed for amino acid concentrations.
Pilot study to test feasibility of 6 months of Duavee® vs wait-list control in post-menopausal women symptomatic for hot flashes.
Hospitalized patients spend the majority of their time lying in bed, even when they are capable of being out of bed. Up to 50% of inpatients suffer functional decline at least in part due to lying in bed after admission, and even those who are not placed on bed rest by their physicians spend an average of 20 out of 24 hours lying in bed. The loss of functional ability and exercise tolerance happens remarkably fast, as early as hospital day 2 (24-48 hours). Functional decline often results in a prolonged hospital stay and the need for additional rehabilitation resources both during and after the hospitalization to return a patient to their baseline functional status. Functional decline has also been associated with excess mortality. The investigators sought to flip the culture of hospital-based care such that the bed was viewed as a place for patients to sleep, and patients would be encouraged to get out of bed when they were not trying to sleep. The investigators hypothesized that patients were unaware of the risks of prolonged immobilization and that the lack of an alternative comfortable place for patients to sit other than their bed contributed to their immobility. Previous studies have demonstrated that mobility protocols improve patient-centered outcomes in narrow patient populations such as post-surgical patients or the elderly, but such interventions have not been studied in a heterogeneous patient population. Additionally, previously studied protocols have been labor-intensive from a nursing standpoint, requiring, for example, that staff provide one-on-one supervised ambulation 3-4 times per day. The investigators aimed to determine whether establishing a relatively low-intensity, pragmatic protocol to discourage patients from lying in bed would result in shorter length of stay by improving mobility. The investigators further aimed to assess the additional impact of providing a recliner chair, a safe and comfortable alternative to their bed on these outcomes. This a prospective, controlled investigation of a novel intervention intended to reduce time subjects spent lying in bed. The intervention will be conducted at Los Angeles County + University of Southern California (LAC+USC) Medical Center from March 20, 2017 through September 19, 2017. The intervention and control wards are symmetrically laid out. All wards consist of medical/surgical beds without cardiac telemetry monitoring. Subjects will be admitted per clinical routine, with bed assignments made by the bed control department, which was not aware of the study. Handouts developed at a 3rd grade level will inform subjects and their families about the risks of bed rest and encouraged the subjects to only lie in bed when they were attempting to sleep. Handouts are translated into 5 languages (Spanish, Korean, Tagalog, Mandarin, Vietnamese). Nursing staff on the intervention wards will provide these handouts to subjects and their families as part of the standard admission process. In addition, laminated reminder signs identical to the handouts will be posted on the wall opposite the head of the bed. Posters were placed in the main entrance of the study units. Half of the intervention rooms will also be provided with recliner chairs (Winco Vero Care Cliner) that were bariatrics rated to 500 pounds, vinyl-covered for facile disinfection, and had 180-degree swing arms and locking casters. The other intervention rooms and the control rooms had standard hospital chairs in addition to the hospital bed. The primary outcome measure is the difference in the length of hospital stay for admissions to intervention rooms compared to control rooms. Subjects' age and gender will be collected in order to control for these factors in the primary analysis. The Medicare Severity Diagnosis Related Group (MS DRG) relative weight for each patient will be collected to control for illness severity. As a secondary endpoint, functional status will be assessed using the "6-Clicks" objective functional scoring system. Scores will be measured at several points during the each hospitalization As a process measure, nurses will maintain a log of hours per shift that subjects spend in bed. Finally, as a safety measure, the rates of falls per 1000 patient-days will be collected. Data will be abstracted using an automated query of the electronic health record's bed management database (Cerner, Kansas City, MO). All patients who are placed on one of the study wards during the intervention period-including those admitted from the emergency department, elective medical and surgical admissions, inter-hospital transfers and intra-hospital transfers-will be included.
In response to Program Announcement (PA)-09-164, "NIH Exploratory/Developmental Research Grant Program (R21) a randomized pilot study testing the efficacy of SWIFT: Social Work Intervention Focused on Transitions among at-risk older adults following hospital discharge to home. This study is drawn from several observations. First, transitions between care settings create elevated risk for poor outcomes and for readmission among older adults leaving the hospital for home largely due to fragmented care and poor communication. Next, while few studies exist that test methods to improve transitions, those available are largely medically focused, using a nurse or advanced practice nurse in their approach. Although evidence exists to support the effectiveness of these models, few have been replicated and none have been integrated into standard health care practice. This may be attributed to several factors including the availability of the needed staff, the lack of existing structures to support these roles, and the costs of implementing these interventions. Finally, a social work driven intervention may provide a replicable mechanism for bridging medical care, addressing psychosocial needs as well as medical needs, and improving linkages with community services while reducing care duplication. This study aimed to test a structured social work transition intervention model to reduce rates of hospital readmission and medical service use while improving patient satisfaction with the care transition process. A randomized pilot study was used to test a social work transitions model designed to improve care provided to frail older adults being discharged from the hospital to return to the community. Eligible patients consenting to participate (n=181) were randomly assigned to either the social work transitions model intervention or usual care. This project was conducted at Huntington Hospital, a 525-bed, nonprofit, community hospital located in Pasadena, California. In an average year, Huntington Hospital has approximately 10,000 older adults discharged from their facility, 44% of who are 80 years old or older. Those randomized to the intervention arm received up to six sessions from the social worker, at least one provided in the home. The social work intervention was designed to overcome common problems following hospital discharge including medication review, discussion and planning around discharge instruction, assistance in scheduling follow up appointments, assessments of psychosocial and other support service needs and provision of linkages to address those needs. Outcomes were measured three and six months following arrival at home, with an interim measure of satisfaction at 10 days following arrival at home, with measures including patient level of depression, pain, physical functioning, self-efficacy with disease management, and medical service use.
Primary Aim A. To determine if listening to prerecorded guided imagery 3 times per week for 4 weeks will reduce state anxiety, perceived stress, burnout, compassion fatigue, and vicarious trauma in Fronltine Service staff. Primary Aim B. To determine if staff will continue to listen to guided imagery after the first 4 weeks of the study is over.
Although the prevalence of "family-friendly" policies in US workplaces has increased dramatically, few have been studied using scientifically sound designs. To address this, the NIH and CDC formed the Work, Family, and Health Network (WFHN). During Phase 1, the WFHN designed and conducted multiple pilot and feasibility studies. For Phase 2, the WFHN implemented an innovative intervention based on Phase I pilot studies that is designed to increase family-supportive supervisor behaviors and employee control over work, and to evaluate the intervention using a group randomized experimental design. Customized interventions were performed separately in workplaces of two separate corporate partners.
The purpose of the study is to create MR images using an investigative technique called pulse sequences with new computer software programs. The sequence will allow us to image vessels without injecting contrast agents.
This study hopes to determine if thromboelastography-derived functional fibrinogen (TEG-FF or FLEV) levels obtained during the rewarming phase of cardiopulmonary bypass can provide information on coagulation status sooner, allowing for anticipation of post-bypass bleeding and transfusion requirements
The purpose of this research study is to determine if the application of ice, control group, or a muscle stimulation program from the Compex® series can help reduce or eliminate delayed muscle soreness from performing leg extension and flexion. Individuals will complete a health history questionnaire to determine if they qualify for this study. We will measure your leg girth with a measuring tape and take a pain measurement of your hamstrings by using a spring to press down on your leg. Individuals will then warm-up on a bike without resistance for 5 minutes followed by 10 regular leg extension and flexion exercises. Individuals will then perform 6 sets of 10 leg extension and flexion exercises on a biodex machine (similar to leg curl machines in the gym). Individuals will perform each set to the maximum effort of their capables. After each set of 10 individuals will have a 2 minute rest. We will ask you to rank your leg soreness on a scale from 1-10. Individuals will then be assigned to a modality of either ice, control group or compex. Individuals will perform the modality (ice, control, compex) we assign you to until you are no longer sore. Over the next five days individuals will return to measure their level of soreness, leg girth and pain pressure. This study will examine the following hypotheses: H1: There will be no difference in pressure pain threshold after using the Compex compared to other groups. H2: There will be no difference in perceived soreness after using the Compex compared to other groups. H3: There will be no difference in muscular strength after using the Compex compared to other groups. H4: There will be no difference in active range of motion after using the Compex compared to other groups.
This study examines in a prospective, randomized and blinded study design the impact of a proficiency based training methodology on the acquisition of arthroscopic surgical skills employing both a dry shoulder simulator model, and cadaver specimens for the demonstration of surgical skill proficiency.
The purpose of this study is to evaluate radiolabeled recovery and survival of autologous red blood cells (RBC), derived from Mirasol-treated fresh whole blood (WB), stored as leukoreduced packed RBC (LR-pRBC), and re-infused in healthy adult subjects
The overall objective of this study is to develop and test an efficient set of self-report instruments to measure Complementary and Alternative Medicine(CAM)-relevant contextual factors important in healing. The initial phase of the study involves developing and refining an item bank. During the initial 'item bank development' phase, the investigators will run focus groups and cognitive interviews with individuals who participate in CAM and conventional medicine interventions. The next step of instrument development is called Calibration, and involves administering the revised item bank to an internet sample and to persons who receive services in a CAM clinic and a conventional primary care setting. The items will be calibrated using item response theory and classical test theory. This will result in a computerized adaptive testing version of the instrument, as well as a static short form of the instrument. This current protocol in ClinicalTrials.gov pertains only to the Calibration Phase of the study. The final phase of the project will involve conducting initial validation studies of the set of instruments. The set of instruments will be called the Healing Encounters and Attitudes Lists (HEAL). The investigators will evaluate the convergent, discriminant, and predictive validity of the HEAL instruments in a sample of 200 persons with chronic low back pain who are receiving physical therapy, chiropractic care, or mindfulness-based stress reduction. For convergent validity, the HEAL is expected to display moderate to large correlations with measures of similar constructs. The HEAL is expected to correlate modestly with self-report measures of general psychosocial functioning, in support of discriminant validity. Finally, HEAL scores should account for a significant proportion of the variance in treatment outcome, supporting predictive validity.
Marijuana (Cannabis sativa) is the most widely used illicit drug worldwide, with 17.4 million Americans reporting past month use in 2010 and 4.6 million meeting criteria for dependence, underscoring the public health importance of understanding the biological implications of use. How heavy cannabis use affects brain structure and cognitive performance in late life is unknown. The ongoing maturation in the adolescent brain, including the developmental circuitry underlying memory performance and executive control puts the adolescent brain at high risk for detrimental effects of heavy cannabis use. With the aging of the 'baby boomer' generation, many people who used cannabis heavily as adolescents are now entering their senior years when age-related cognitive decline may begin. Cannabis use doubled in less than a decade during the 1970's when 38% of those surveyed in the U.S. Survey on Drug Abuse reported using cannabis and 12% of those users reported using cannabis more than 20 times a month. Understanding how heavy, early cannabis use may affect neurobiological and cognitive outcomes is of high importance for this aging population, which is already at risk for memory and cognitive deficits in aging. Because cannabis use appears to have a primary effect within the hippocampus, the main structure for memory and the structure affected most by age-related memory impairments and pre-clinical Alzheimer's disease, we expect that the effects of chronic cannabis use may be greatest during aging. To our knowledge, no study has investigated the long-term effects of adolescent cannabis use on hippocampal morphology and cognitive performance in an aging population. Investigators will investigate hippocampal integrity and cognitive performance using high-resolution magnetic resonance imaging (MRI), diffusion tensor imaging (DTI) and neuropsychological testing in an aging population of subjects (55-70 years old) who used cannabis more than 20 times a month for at least a year during adolescence. Investigators will compare data collected from heavy cannabis users to subjects who did not use cannabis but are matched for age, gender, education, light tobacco and light alcohol use. Finally, because family history and genetic risk are known to accelerate hippocampal morphology and memory decline in aging, the investigators will investigate whether possession of the APOE ε4 variant in heavy cannabis users is synergistically related to thinner hippocampal cortex and white matter deficits.
The goal of this study is to determine if papaya fruits are an exceptionally good food source for carotenoids in humans, particularly when compared more common carotenoid sources like carrots and tomatoes. This objective will be accomplished by quantitation of the immediate post-prandial plasma concentrations of parent carotenoids and vitamin A metabolites from subjects who consumed a meal containing fresh papaya, tomato, and carrot.
A standard PET/CT scanner is comprised of two different machines: An X-ray computed tomography scanner (CT), which gives information about your anatomy, and a Positron Emission Tomography scanner (PET) that provides information about how the body functions. Both of these work together to make the final images for doctors to review. As part of this research study the investigators would like to test a new scanner technology by evaluating the quality of the images obtained using this new PET system. The scanner the investigators would use is able to do both types of examination, the standard PET/CT and the additional research PET. The new PET system adds a second scanner ring to the standard PET/CT. This allows the patient to stay on the same imaging table for both studies. Being in this study does not change how the standard PET/CT will be done.
The proposed study will investigate the effects of intranasal oxytocin administration on neural activity associated with social and non-social motivation.
This proposal hypothesizes that oral supplementation with sodium nitrite or nitrate will result in in vivo conversion of nitrate to nitrite and nitrite to nitric oxide with limited toxicity in the doses proposed in healthy adult normal volunteers. We utilize a powerful in vivo technique (pharmacokinetic testing) and are the first to design inorganic nitrate and nitrite capsules for cardiovascular disease.
Flank pain has been reported with ultrasound (US) contrast agents. The purpose of this study is to determine whether there is retention of ultrasound contrast agents in the renal microcirculation, which has been described in mice.
The hypothesis was that the implementation of a Safe Kids East Central brain injury prevention program targeting children and caregivers admitted to the Georgia Health Sciences University Children's Medical Center is feasible and that short-term treatment effects of injury prevention education on the child or adolescent and the caregiver will increase bicycle helmet use.
The purpose of this study is to determine whether the intervention Daily Challenge (MeYou Health, LLC), a behavioral intervention delivered online, is effective in improving individuals' well-being.
