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.
Does baseline impedance measured during the landmark phase of esophageal High resolution impedance manometry HRIM correlates with direct mucosal impedance measurement and discriminates GERD from non GERD patients?
Sleep disturbance has been reported in 44-86% of children with autism spectrum disorder (ASD) and is the source of considerable stress for the affected individual and family. Sleep plays a role in development and learning processes; thus, the appropriate treatment of sleep disturbance is paramount to optimal outcomes. The empirical base for treatments to address sleep in ASD is sparse, despite wide use of pharmacologic agents such as clonidine (CLN) to target sleep disturbance. A randomized, controlled pilot investigation of CLN for sleep disturbance in children with ASD will allow investigators to evaluate the feasibility of conducting a much larger multisite trial to address the general lack of systematic data available to guide practitioners. Subjects will be 16 children, ages 6-14 years, inclusive, with sleep disturbance and ASD. This randomized double-blind, placebo-controlled (PBO), parallel groups study will test the efficacy of CLN following a brief sleep hygiene intervention. Outcome measures include: informant completed sleep questionnaires, daytime behavior questionnaires, and actigraphy. Biomarkers for medication response will include galvanic skin response and skin temperature. Side effects will be monitored throughout the study.
The purpose of this study is to develop an interactive web-based patient education program to help educate patients about the increased risk of MS and its cardiac risk factors following allo-SCT and to inform and motivate patients how to make lifestyle changes. This program will be used in addition to counseling at participants clinic visits. The investigators are not changing the recommendations for prevention and management of these conditions, but rather are trying to improve the way they provide this education to patients.
Hypothermia during surgery and in the postoperative period is associated with adverse outcomes including impaired drug metabolism, cardiac morbidity, shivering, impaired immune function, coagulopathy, and increased use of hospital resources. Several clinical studies have demonstrated that maintenance of normothermia during the perioperative period significantly reduces morbidity. Mercury Biomed has developed a patient-warming system, WarmSmart, that potentially transfers adequate heat through hands and feet based on the physiological principle of peripheral arterio-venous shunt vaso-dilation. The technology works as a two-step process by selective thermal stimulation along the spinal cord to up-regulate blood flow to arterio-venous shunts and triggering arterio-venous shunt vasodilation and by applying circulating water heat exchangers to the palmar and plantar glabrous skin to warm highly perfused shunts in that area. General anesthesia reduces the vasoconstriction threshold (triggering core temperature) by 1-2°C, thus promoting arteriovenous shunt dilation. It remains unknown, though, whether cervical spine warming further augments arterio-venous shunt dilation during general anesthesia. If spine heating proves unnecessary under anesthesia, Mercury Biomed's WarmSmart warming could be simpler and less expensive. Investigators therefore propose to test the hypothesis that cutaneous heating near the cervical spine does not further augment arterio-venous flow in fingers during general anesthesia. Investigators propose to enroll ten patients. The patients will be pre-warmed and warmed intraoperatively with forced-air to maintain a core temperature near 36°C. A ThermaZone® Device capable of heating the cervical spine area will be positioned behind the patient's neck upon arrival in the operating rooms. Additionally a forced-air warmer will be positioned appropriately and activated as soon as practical, usually after prepping and draping. Ambient temperature will be maintained near 20°C. After about one hour of anesthesia when temperature and other factors are stable, investigators will start a 30-minute observation period. Thereafter investigators will activate the cervical spine warming system for 30 minutes (warming measurement period) and thereafter have a 30 minutes control period again. Measurements will be recorded such as mean-skin temperature, distal esophageal temperature, MAC fraction, mean-arterial pressure and finger blood flow.
This study is open to men who have biochemical recurrence (BCR, increased PSA) following local treatment of their prostate cancer. Androgen deprivation therapy (ADT) is a standard treatment option, but is only effective for 16-24 months and has a number of side effects that impact quality of life. These side effects may include fatigue, hot flushing, loss of sex drive, brain fog, decreased bone mineral density, loss of muscle mass, mild anemia (low levels of red blood cells that can make people feel tired and weak), diabetes (low blood sugar), heart disease, metabolic syndromes (sometimes called "pre-diabetes" and includes obesity, increased blood pressure, high levels of cholesterol and triglycerides in blood), and risk of fractures. An alternative to continuous ADT is intermittent administration, where patients are given "breaks" from ADT to let their testosterone levels return to baseline. There are a number of potential benefits to intermittent hormone therapy (IHT): (1) longer time to the development of resistance; (2) improved patient quality of life owing to recovery from adverse effects, particularly sexual function; and (3) substantial cost savings owing to less time spent receiving medication. Leuprolide is the name of the ADT / IHT drug. Apalutamide is an investigational drug, which means it has not been approved by the Food and Drug Administration (FDA). It is an antitumor drug, taken by mouth. The purpose of this study is to determine the ability of Apalutamide to extend the time between the first two injections of leuprolide and improve quality of life. This study will also look at the safety of Apalutamide and the effects that Apalutamide has on prostate cancer. Men will be randomized (like flipping a coin) to receive: - Group A: Leuprolide + Apalutamide or - Group B: Leuprolide only (until second leuprolide injection), then leuprolide + Apalutamide 45 men will be in Group A and 21 men will be in Group B. Leuprolide is given as an intramuscular shot that lasts for 3 months intermittently and Apalutamide is taken by mouth (4 tablets) daily. Each cycle is 4 weeks long. Intermittent treatment with Apalutamide + leuprolide will continue until continuous leuprolide is needed to maintain undetectable PSA levels (i.e., PSA levels rise above undetectable level unless leuprolide is given without pause, every 3 months).
The purpose of this study is to see what the effects of using one or two additional diabetes drugs (dapagliflozin and exenatide-LAR) are on blood sugar levels in patients who are taking insulin. This research study is being done to investigate which of these commonly-used medications, medication combinations or increasing insulin dose is better.
This is an open trial that seeks to determine the safety and tolerability of using inositol for children and adolescents with bipolar disorder and comorbid anxiety disorders with an exploration of efficacy and dose-response.

The purpose of this study is to determine the efficacy of sphenopalatine ganglion (SPG) block to prevent shoulder tip pain following primary laparoscopic gastric banding, band revision, band replacement, primary sleeve gastrectomy or revision of sleeve gastrectomy. Shoulder tip pain (STP) is a common problem after laparoscopic surgery, manifesting in the post-anesthesia care unit and for days or possibly weeks thereafter (Dixon 2005). Systemic analgesics including opioids and non-steroidal anti-inflammatory drugs (NSAIDs) do not reliably relieve STP. This study is designed to determine if the SPG block, a simple and low-risk procedure, effectively treats STP after laparoscopic bariatric surgery.
The objective of the study is to determine the quality of life of patients in the years following treatment with extracorporeal membrane oxygenation (ECMO). The study population will include all adults treated with any configuration of ECMO at Duke University Medical Center during the period of Jan 1, 2009 and Dec 31, 2015. Patient's will be contacted by direct mail, in conjunction with a surgeon who performed their ECMO procedure or managed them while on ECMO, and asked to complete a validated survey (WHOQOL-Bref) which assesses quality of life. In addition, patients will be asked to opt-in to participate in a phone survey in which they can give a narrative about their ICU experience and answer specific questions regarding long-term comorbidities. Data will be stored in a secure online server which is HIPAA compliant and analyzed by the department of anesthesiology statistical support services. De-identified data will be shared with the WHO as specified in their usage agreement.
