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 study is to determine the feasibility and toxicity of combining SBRT and TACE for unresectable HCC and to evaluate the Health Related Quality of Life (HRQL) associated with combined therapy.
Traditionally, obesity is considered an indirect cause of heart disease. Obese individuals typically present with a number of traditional Framingham risk factors (hypertension, dyslipidemia, and type 2 diabetes), predisposing them to heart attacks and subsequent heart failure. However, an emerging body of basic research revisits a hypothesis that fat is a direct cardiotoxin. Under healthy conditions, most triglyceride is stored in fatty tissue (adipocytes) while the amount of triglyceride stored in non-adipocyte tissues (such as the pancreas, the liver, skeletal muscle, and heart) is minimal and very tightly regulated. When this regulation is disrupted, intracellular triglyceride accumulates excessively in these organs ("steatosis") and has been implicated in activating adverse pathways which culminate in irreversible cell death ("lipotoxicity"), leading to several well-recognized clinical syndromes. These include non-alcoholic steatohepatitis (NASH), pancreatic beta-cell failure in type 2 diabetes, and dilated cardiomyopathy. It has been recently observed that angiotensin II receptor blockers (ARBs) in addition to lowering blood pressure improve insulin sensitivity and decrease the risk for type 2 diabetes. This study will test the above theory in two study groups: Valsartan vs. Hydrochlorothiazide. We hypothesize that in obese humans with elevated myocardial triglycerides, blockade of the renin-angiotensin system (Valsartan group) will reduce myocardial fat with improvement of insulin sensitivity and heart function.
The proposed research will investigate whether the irregular effects of atrial fibrillation on the body's circulation directly impacts the regulation of cerebral blood flow. To further delineate this finding, investigation of these potential effects will include differences in postural positioning. This data will be used to further understand the overall hemodynamic effects of atrial fibrillation on extra-cardiac organs of the body.
The purpose of this study is to determine what effect sodium oxybate has on the functions of sleep in mechanically ventilated, critically ill patients hospitalized in an intensive care unit.
Trauma continues to be the major killer of young Americans, mainly due to hemorrhage or brain injury. In trauma centers, up to a quarter of these severely injured patients arrive with a coagulopathy and thereby experience an increased risk of death, despite the current standard of medical and surgical management. The PI for this grant proposal is a fellowship-trained trauma surgeon who works full-time at Grady Memorial Hospital (GMH), the only Level I Trauma Center in Atlanta. It is only one of four Level 1 trauma centers for the entire state of Georgia. This research is a direct extension of the retrospective research the PI has previously published. Her retrospective research discovered a previously undescribed form of coagulopathy, early trauma induced coagulopathy (ETIC), which cannot be explained by present paradigms. Two civilian trauma articles as well as military data from the Iraq war have substantiated the occurrence of ETIC, but no prospective literature has defined it or its kinetics. More importantly, the results from these studies represent a new paradigm shift, in which ETIC appears to be a primary dysfunction which is independently associated with death. Therefore, its early identification and correction is crucial for our mechanistic understanding, and ultimately, our choice of interventions and improved survival. GMH is a high-volume trauma center that sees patients with a variety of injury mechanisms, and, therefore, is the perfect setting to confirm ETIC. First, the project will confirm the prevalence of ETIC with an observational prospective cohort of injured patients. Data on the coagulation system and risk factors, both known and suspected, of all patients will be collected upon patient arrival as well as patient outcome with all identifying information protected. This is the first prospective research project that will allow simultaneous control of confounders associated with outcome and thereby scientifically validate the occurrence of ETIC. One unique component of our data collection is a focus on the timing of events as they relate to the development and consequences of coagulopathy, to account for the dynamic process. At the completion of data collection, a matched cohort of ETIC and non-ETIC blood samples will be tested for coagulation factors to provide insight into ETIC's pathophysiology. In the short term, our conclusions will assist us in our approach to resuscitation of the bleeding trauma patient as some trauma centers have already started to change protocols based on our present incomplete understanding of trauma-induced coagulopathy. In addition, the coagulation system data collected in this study will lead to pathophysiological answers and to more refined hypotheses for future research at a coagulation system level. Ultimately an understanding of ETIC will lead to a more effective, tailored treatment. Our main study hypothesis is that post-trauma coagulopathy is a primary dysfunction that occurs early after a traumatic event in up to 25% of all trauma patients triaged to Trauma Center care.
The purpose of this study is to determine whether the intravenous administration of single- and multiple-ascending doses of Thymosin Beta 4 is safe and tolerable in healthy volunteers.
This study aims to determine whether respiratory system transfer impedance (Ztr) may fill an important clinical function by providing a reproducible, valid, and sensitive measure of airway obstruction in people with CF.
The primary objective is to compare the clinical outcomes of patients with a clinical diagnosis of Adhesive Capsulitis who receive intra-articular versus subacromial steroid injections. The secondary objective is to verify that steroid injections in combination with physical therapy lead to more favorable outcomes than local anesthetic injections in combination with physical therapy.
Premature infants are at risk for developing bronchopulmonary dysplasia (BPD). L-citrulline may decrease that risk, but we do not know the safety or dose of this drug for use in premature babies. The purpose of this study is to determine the safety and optimal dose of intravenous L-citrulline in premature infants.
The purpose of this study is to determine if Advair Diskus improves sleep quality by reducing lung hyperinflation in COPD.
