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.
A randomized, controlled trial to evaluate patient compliance and biologic mechanisms of a short-term pre-operative Protein-Calorie Restriction (PCR) diet in comparison to a normal ad libitum diet for 4 days before elective vascular surgery involving a major operation. After a pilot study exploring the safety and feasibility of the PCR diet conducted inpatient before carotid endarterectomy titled Short-Term Endogenous Hydrogen Sulfide Upregulation, and a follow-up study titled Dietary Restriction in Vascular Surgery, the investigators now aim to expand the study to at home diet among a variety of vascular surgery procedures. This study will further elucidate not only the practicality of pre-operative short term dietary restriction, but also provide early data to inform biologic mechanisms and to inform future efficacy trails.
Serious mental illnesses (SMI) like schizophrenia and bipolar disorder are two of the most disabling and costly chronic illnesses worldwide. A high proportion of adults with schizophrenia and bipolar disorder have sleep disorders, like obstructive sleep apnea (OSA), but tend to be underdiagnosed and undertreated compared to the general population. This study aims to examine feasibility, acceptance, and impact of OSA treatment and how it affects cognitive function in people with SMI.
This clinical trial assesses the feasibility and acceptability of the psychosocial intervention peer caregiver navigation (PCN) in an outpatient oncology setting. PCN is a peer mentoring service designed to help family caregivers navigate and mitigate the distress of caregiving by enhancing and promoting the emotional and behavioral coping efforts of the caregiver.
This phase I/II trial assesses the safety and effectiveness of total pancreatectomy with islet cell autotransplantation for the treatment of patients with long-term pancreatic inflammation (chronic pancreatitis) and non-cancerous (benign) pancreatic tumors. Total removal of the pancreas (pancreatectomy) can be used to treat chronic pancreatitis, but it may result in diabetes. An islet cell autotransplantation involves removing cells from a patient's pancreas (the islet cells) and infusing them into the liver. Islet cells are responsible for producing hormones like insulin, reducing the occurrence of diabetes in patients undergoing total pancreatectomy. Total pancreatectomy with autologous islet cell transplant is an accepted and Food and Drug Administration-approved treatment for patients with chronic pancreatitis. However, patients with chronic pancreatitis and pancreatic tumors have historically not been candidates for this procedure due to concerns of spreading potentially cancerous cells to other parts of the body. This clinical trial evaluates the safety and effectiveness of this treatment in patients with chronic pancreatitis and benign pancreatic tumors.
Study Design: A Window of Opportunity Clinical Trial. This study design permits examination of effects of an oral agent on cancer patients during the "window" between diagnosis of their cancer and their definitive cancer surgery. Similar to a phase 0 study, the trial design permits examination of the biologic effects of an agent; in this study pharmacokinetic properties will be examined.
Prior multicenter study demonstrated superiority of PURE EP to conventional mapping. This superiority was seen when comparing small, fractionated signals of interest, near-field vs far-field distinction, and general signal quality (2). Hence, investigators propose a retrospective study to assess the predictive value of high frequency algorithm (HFA) for identifying local physiologic signal under 0.3 mV distinctive of noise.
The Aims of this study are 1) to develop a traditional plant-based diet that is palatable and acceptable to the Latino population and which contains the appropriate calorie and macronutrient composition needed to lose weight and improve metabolic function and; 2) to develop a culturally sensitive (based on previous literature and stakeholder input) lifestyle intervention program, that will be delivered by community health workers (CHWs), that focuses on consuming a traditional plant-based diet and overcoming the barriers to incorporating this dietary therapy as part of the family lifestyle but with a focus on the adult participant with obesity. Ultimately, in Aim 3 the investigators will conduct a 16-week randomized controlled trial (RCT) in 40 Latino adults with obesity (20 control, 20 treatment) to evaluate the intervention's: i) clinical efficacy; ii) fidelity of the implementation by CHWs; and iii) acceptance by CHWs and study participants. The current status of the RCT is not yet ready to begin. The current activities are only preparatory to research, and/or activities that do not involve human subjects research (Aims 1 and 2). The investigators will submit a separate project before conducting the human subjects research that is described in this In-Concept project.
It is unknown if applying superficial dry needling to the trigeminal innervation field improves pain and disability for patients with cervicogenic headaches. The aim of this study is to determine if superficial dry needling of the trigeminal innervation field improves pain, neck mobility, and disability in patients with cervicogenic headaches. It will also be examined if psychosocial factors such as stress, anxiety, depression and self efficacy influence improvements in pain, range of motion and neck disability.
Mobile health applications (mHealth apps) are transforming medical research and intervention by allowing constant, instantaneous and personalized access to patients. The investigators have designed a mHealth app (Stanford SpineKeeper) utilizing the Apple ResearchKit and HealthKit platform, which is an open source software framework designed Apple Inc to be used by medical researchers to use for research purposes. The investigators will assess whether a multidisciplinary intervention delivered through the application can help improve quality of life and minimize symptoms in patients with chronic low back pain.
This is a randomized pilot study to test the acceptance and use of PerHL among formerly incarcerated individuals
