This study is a test of possible mechanisms by which calorie labels might lead people to increase calorie intake. The investigators hypothesize that calorie labels might increase calorie intake because 1) people infer that higher calorie foods are tastier, 2) calorie labels invoke thoughts of dieting, leading people to overconsume as a reaction, 3) people try to maximize calories consumed per dollar spent, and 4) calorie labels change one's goal motivation toward food, causing people to eat more.
The investigators found that community acquired C. diff occurs in children undergoing a colonoscopy. When they were treated their symptoms got better. But, the investigators do not know if the treatment for the C. diff made them better or another other factor made them feel better. So, the investigators designed the following study. Children undergoing a colonoscopy who are found to be C. diff positive at the time of the colonoscopy are randomized to one group that gets immediate treatment or a second group that gets delayed treatment. Both groups are closely monitored for symptoms.
The pathogenesis of chronic fatigue syndrome (CFS) is poorly understood and no effective therapy has been developed. Recent studies suggest that a preceding viral infection causes mitochondrial dysfunction of the brain and skeletal muscle of genetically susceptible individuals. There is no specific laboratory test to identify patients with CFS. However, certain clinical manifestations are similar to those seen in mitochondrial disorders. Both patients with mitochondrial disorders and CFS manifest elevated serum lactate levels after exercise, and demonstrate elevated brain cerebrospinal fluid levels and decreased brain glutathione levels on nuclear magnetic resonance (NMR) spectroscopy. Therapy consisting of daily conditioning exercise, dietary recommendations, and nutraceutical supplements (ENT) has been show to be beneficial in treating patients with mitochondrial disorders. Similar therapy has been instituted in individual patients with CFS and has been shown to also improve their clinical conditions. A placebo-controlled trial will be undertaken in 24 CFS patients aged 25-55. Patients fulfilling the CDC criteria for CFS will participate in this 6 month study. Other medical causes for fatigue will be excluded. Half the patients will receive treatment consisting of daily conditioning exercise plus nutraceutical supplements (ENT), that has been shown to be beneficial for patients with mitochondrial dysfunction, while the other half will receive daily conditioning exercise and placebo tablets. Response to ENT will be evaluated by maximum oxygen consumption (VO2max) and circulating lactate levels during & after treadmill exercise, a 6-minute walk test, and a fatigue questionnaire. In addition, whether ENT corrects the elevated brain cerebrospinal fluid levels and decreased brain glutathione levels will be measured. To ensure compliance to therapy patients will be monitored frequently. The objective of this study is to assess the safety and efficacy of ENT and whether ENT leads to sustained improvement of CFS patients compared to their baseline status, and compared to an exercised group of patients not receiving supplements.
Temporomandibular joint disorders (TMD) are a common musculoskeletal problem with an estimated 40-75 percent of the population reporting at least one sign. Up to fifteen percent of the patients who seek care for one of these conditions, will go on to develop chronic pain. The two most common TMD conditions include myofascial pain disorder and internal derangement of the Temporomandibular Joint (TMJ). These two conditions have similar clinical presentations, making an accurate diagnosis difficult. Currently, there is no accurate exam or test to differentiate between these two conditions. Internal derangement of the TMJ is a condition with disk displacement, pain, and dysfunction, which may progress to localized osteoarthritis. Fortunately, this condition is self-limiting for the majority of the patients afflicted, with a small minority progressing to advanced joint destruction, disability and chronic pain.18 Currently there are no prognostic indicators to identify these individuals. There are three hypothesis of degenerative TMJ disease, they include: direct mechanical trauma, hypoxia reperfusion injuries, and neurogenic inflammation. All involve parafunctional habits such as clenching or grinding by the patient and a low-grade inflammatory response/synovitis. 18-fluorodeoxyglucose (18-FDG), a radioisotope used with positron emission tomography (PET) and paired with a CT scan (PET/CT), may have a role in imaging inflammation in arthritis as recently demonstrated in several pilot studies involving osteoarthritis of the knee and shoulder. 18-FDG accumulates in areas of increased metabolism, particularly activated leukocytes, as measured by increased standardized uptake value.2 PET/CT offers the unique advantage of showing active disease before anatomic damage is evident. Our hypothesis is that there is an increased uptake of 18-FDG on PET/CT in synovitis of the TMJ.
The purpose of this study is to analyze and identify pre-, intra-, and post- operative parameters that predict Steal-Syndrome with distal malperfusion after Arterio-Venous Fistulas (AVF) as primary endpoint. Secondary endpoints are pre-, intra-, and post- operative parameters that predict patency and fistula maturation.
This study will be an open-label, single-treatment, single-dose, parallel group study to evaluate the pharmacokinetics (PK) of droxidopa in subjects with mild, moderate, and severe renal dysfunction and End Stage Renal Disease (ESRD) after a single dose compared to matched healthy subjects with normal renal function. A total of 48 male or female subjects, 16 subjects with normal renal function (eGFR greater than 90 mL/min/1.73m²) and eight each (8) with mild (60 less than eGFR less than 89 mL/min/1.73m²), moderate (30 less than eGFR less than 59 mL/min/1.73m²), or severe (15 less than eGFR less than 29 mL/min/1.73m²) renal impairment or ESRD (eGFR < 15 mL/min/1.73m² and requiring hemodialysis) will be selected according to the inclusion and exclusion criteria. The medical and laboratory examinations will take place within 28 days before dosing. A single dose of 600 mg of droxidopa as an investigational drug will be administered with 240 mL of water after an overnight fast (minimum 10 hours). Blood samples for the measurement of plasma concentrations of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid will be collected before and 0, .5, 1, 1.5, 2, 3, 4, 5, 6, 8, 10, 12, 24, 30, 36 hours after dosing for healthy volunteers and subjects with mild, moderate, and severe renal impairment and those with ESRD. For the latter, samples will be collected on both a non-hemodialysis and a hemodialysis visit. During dialysis, samples of dialysate, from the arterial and venous sides of the dialyzer will be collected at 30-minute intervals during the dialysis period. In addition, the entire dialysate will be collected, its volume recorded, and a sample retained for the measurement of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid concentrations. Urine samples for the measurement of urinary excretion of droxidopa and metabolites including but not limited to 3-OM-DOPS, NE, vanillic acid, and protocatechuic acid will be collected before and over the following intervals after dosing: 0 2, 2-4, 4-6, 6-8, 8-12, 12-24, and 24-36 hours for healthy volunteers and subjects with mild, moderate, and severe renal impairment. A post-study visit with physical examination and laboratory tests will take place within seven (7) days after the last PK blood sampling.
This phase I/II trial studies the side effects and best dose of linsitinib when given together with erlotinib hydrochloride and radiation therapy after surgery in treating patients with advanced or recurrent head and neck cancer. Erlotinib hydrochloride and linsitinib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Radiation therapy uses high-energy x-rays to kill tumor cells. Giving radiation therapy together with erlotinib hydrochloride and linsitinib may kill more tumor cells. Giving these treatments after surgery may kill any tumor cells that remain after surgery.
The purpose of this study is to determine the short-term (2 yr) and midterm (5 yr) cumulative revision rates of the EPIK⢠Uni-compartmental Knee System.
