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.
Animal and human data have supported the notion that administration of large doses of Vitamin C has beneficial effects on those subjects suffering from large burns. This effect may be due, in part, to the antioxidant and free-radical-scavenging properties of Vitamin C. These studies have demonstrated an improvement in urine output during resuscitation and reduced need for fluid volumes during resuscitation. In turn, these subjects demonstrated a reduction of wound edema, improved respiratory status (demonstrated by improvements in P:F ratios and reduced ventilator days), and no differences in terms of the possible complications of high-dose vitamin C administration between standard and treatment groups. The purpose of this study is to prospectively determine if Vitamin C can be safely used as an adjunctive treatment for patients suffering severe thermal injuries. High-dose vitamin C administered at a dose of 66mg/kg/hr during the acute phase of severe burn injuries will reduce fluid requirements in the first 48 hours after injury.
It is hypothesized that it is both safe and feasible to use an interventional approach to LV lead placement (placing the LV lead guided by acute hemodynamic measurements), and that the LV lead can be placed in a position that is superior to the initial empiric lateral wall LV lead location in less than 30 minutes without significant risk to patients. The time from RV capture to LV activation correlates with the optimal pacing site based on stroke volume & dP/dt measurements.
The objective of this study is to perform a randomized controlled trial among female patients with a diagnosis of pelvic floor hypertonus (extreme muscle tension) with associated pain, dysfunctional voiding, dyspareunia, and/ or obstructed defecation.
This research study is a Phase I clinical trial. Phase I clinical trials test the safety of an investigational intervention (in this case, the stereotactic radiation boost). Phase I studies also try to define the appropriate dose of the investigational intervention to use for further studies. "Investigational" means that the stereotactic radiation treatment is still being studied and that research doctors are trying to find out more about it. It also means that the FDA has not approved a stereotactic radiation boost for your type of cancer. In this research study, the investigators are looking for the highest dose of the stereotactic radiation boost that can be given safely. Because the stereotactic radiation boost is so precise, the investigators are testing whether it can be used to increase the dose to the primary tumor without significantly increasing the side effects you experience; the goal is to improve the likelihood of successfully treating the tumor.
The purpose of the study is to evaluate the effectiveness of the CADence system, a non-invasive device, in detecting greater than or equal to 50% coronary stenosis anywhere in the coronary tree.
Comorbid substance abuse leads to many deleterious effects such as medical comorbidities and nonadherence, which is one of the most problematic issues. People with schizophrenia and substance use disorders (SUDs) are at an increased risk nonadherence compared to those who do not use alcohol and illicit drugs. The investigators propose that this new marketed injectable antipsychotic with many benefits over other available long acting injectable agents would be beneficial in the dually diagnosed population and may represent a specific schizophrenia subpopulation where long acting agents may be considered an important therapeutic option.
The primary purpose of the Adenovirus Vaccine Pregnancy Registry is to prospectively collect data concerning: 1. Pregnant women exposed to Adenovirus Type 4 and Type 7 Vaccine, Live, Oral, 2. Potential confounding factors, and 3. The outcome of these pregnancies. The secondary purpose of the Adenovirus Vaccine Pregnancy Registry is to evaluate the frequency of birth defects in prospectively enrolled pregnant women. This Registry is also designed to detect any unusual patterns of birth defects.
The pilot study will evaluate whether electronic-Measurement Based Care (e-MBC) using the UT Southwestern MyChart personal health record is feasible, associated with patient and health care team satisfaction, and improves treatment outcomes compared to a standard treatment model. The project will be conducted in the Simmons Cancer Center Clinic at the University of Texas Southwestern Medical Center, Dallas as a collaborative effort between the Departments of Psychiatry, Oncology, and Family and Community Medicine. The primary patient population will include adults with significant depression and/or starting an antidepressant treatment and/or experiencing a treatment change. The study will compare two groups, an e-MBC group and an office-based standard care MBC group. Study staff will explain the study to the patients, specifically explaining that study participants will receive either office-based MBC or e-MBC. Eligible participants must be willing to receive either form of treatment monitoring. Participating patients will be randomly assigned to receive either e-MBC or office-based MBC. In the e-MBC group once a month the study nurse will send a prompt from the participating patients treating physician requesting the patient to use the MyChart system to fill-out the MBC scales. Beyond these monthly assessments, patients will be encouraged to utilize the MyChart MBC assessments (e-MBC) at any time to communicate with their physician. Patients experiencing difficulties using the e-MBC system will be given additional instruction by the study nurse. Patients and physicians will be trained in the use of the eMBC system. In the office-based MBC group the study nurse will schedule monthly treatment visits and request the patient call as needed to report symptoms. The evaluation period will be 6 months.
The investigators propose to adapt and pilot test a behavioral intervention for recently diagnosed patients with Amyotrophic Lateral Sclerosis (ALS), and/or a family care partner. ALS fatal neurodegenerative disease, the diagnosis of which can have a devastating impact on patients and their families. Our eight session intervention is derived from Coping Effectiveness Training, a manualized intervention based on stress and coping theory. It is designed to strengthen coping skills and alleviate distress following diagnosis. Participants (patients and/or care partners) will be recruited from the Eleanor and Lou Gehrig MDA/ALS Research Center, Columbia University. The main outcomes are changes in distress level, depression and anxiety symptoms, and coping self-efficacy. Once the investigators gain preliminary experience with the manual, get some sense of feasibility and acceptance, and learn about patient and care partner reactions, the investigators will be better able to prepare a grant application seeking NIH support for the development of the intervention, with the eventual goal of a multisite randomized controlled trial (RCT).
The investigators hypothesize that exercise in postmenopausal breast cancer survivors will result in an increase in the plasma concentrations of angiostatic factors and a decrease in the plasma concentrations of angiogenic factors. Exercise is expected to result in a circulating angiostatic phenotype that inhibits adipose tissue mass, growth of breast cancer tumor, growth of microscopic residual disease after breast cancer resection, decreases rates of local-regional recurrence, decreases rates of distant recurrence, and increases survival.
