Filter by:The objective of this project is to design a Behavioral Economics Based Online Lifestyle Balance Program that employs behavioral economics to engage and motivate adherence to an Internet-based program. The investigators compare the effects of two financial incentives on inducing weight loss: a direct financial incentive for weight loss and a financial incentive for health literacy.
This phase II trial studies the side effects and best dose of venetoclax and romidepsin to see how well it works in treating patients with mature T-cell lymphoma that has come back (recurrent) or does not respond to treatment (refractory). Venetoclax and romidepsin may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth.
Dental bleaching is a simple procedure for aesthetic restoration of vital and non-vital discolored teeth. Nevertheless, a number of studies conducted previously demonstrated the risk of tissue damage from contact of these agents with the oral mucosa along with their possible genotoxic potential after exposure to oral mucosa. Hence the aim of this study is to conduct a human clinical trial to incorporate the chemoprotectant N-acetyl cysteine (NAC) in the procedure of bleaching which could safely be used to eliminate the toxicity of bleaching materials leaving their esthetic benefits intact. 30-40 human subjects will be recruited and bleaching will be done at the UCLA School of Dentistry dental clinic.
Pivotal Clinical Trial to Evaluate the Efficacy and Safety of UNI-DEB for Unresectable Hepatocellular Carcinoma
The purpose of this study is to compare success rates of antegrade and retrograde intravenous (IV) catheters in their ability to aspirate 20 milliliter blood sample within a 2 minute time frame, 3 hours after initial insertion. Antegrade IV catheters are placed identically to conventional IV catheters, with the end of the catheter pointed toward the direction of blood flow to the heart. Retrograde catheters are placed "backwards" with the end of the catheter pointed away from the direction of venous blood flow. The hypothesis is that retrograde IVs will have a significantly higher success rate of blood draw at the 3 hour time mark without use of a proximal tourniquet.
The 2016 WHO antenatal care guidelines stated that pregnant women in undernourished populations should receive fortified balanced energy-protein (BEP) supplements to reduce the risk of stillbirth and small-for-gestational-age birth. However, acceptable supplements and delivery channels must be determined for different contexts. The present proposal therefore will 1) perform a formative study to identify the most suitable (acceptability and utilization) BEP supplement for pregnant women in rural Burkina Faso (phase 1) and 2) evaluate the efficacy of this supplement to improve birth weight, fetal and infant growth (phase 2). The nutritional composition of the BEP supplement was established during an expert convening at the BMGF in September 2016. Private sector partners will prepare the supplements in the selected forms with the recommended nutrient composition.
The purpose of this study was to evaluate the functional outcome in patients with a midshaft clavicle fracture treated with to different techniques. the first one was placing a 3.5mm reconstruction plate in the superior side of the clavicle and the second one placing the same 3.5mm reconstruction plate in the anteroinferior side of the clavicle. the patients had the same rehabilitation program and evaluated with functional scores at 30, 60, 90 and 365 days after surgery. biomechanical studies have demonstrated more stable construct using an anteroinferior plate in clavicle fractures and we were trying to find out if it has a clinical relevance in patients with midshaft clavicle fractures.
L-theanine and caffeine are two natural constituents of tea. Both of these compounds are among the U.S. Food and Drug Administration's list of Generally Recognized as Safe (GRAS) substances. Results of several clinical trials the PI and his team has conducted are consistent with results of many others to indicate that oral intake of each of 2.5 mg/kg body weight of L-theanine and 2.0 mg/kg body weight of caffeine is associated with improved attention in adults. Furthermore, there is evidence to suggest that, when taken in combination, L-theanine and caffeine seem to have additive effects in improving attention in adults. However, the specific actions of these substances have not been examined in children and adolescents with attention deficit hyperactivity disorder (ADHD), who are characterized by impaired attention, hyperkinesia and impulsivity. Therefore, the investigators plan to study the functional activity of brains (both at rest and when performing standard tasks designed to measure attention) in children diagnosed with ADHD using functional magnetic resonance imaging, after they consume either 2.5 mg/kg of L-theanine, 2.0 mg/kg of caffeine and their combination as compared to a placebo (water). Based on our previous findings, the investigators expect to observe improvements (speed of responding and accuracy) in standard tests of attention with intake of L-theanine, caffeine and their combination as compared to the placebo. The investigators also expect to observe decreased functional activity in brain regions that typically show increased activity during mind wandering with intake of L-theanine, caffeine and their combination.
The study aims to determine whether there is a need for preparative fasting prior to contrast-enhanced computed tomography (CT).
This trial investigates effects of a glucagon bolus injection on heart rate, blood pressure and cardiac output during beta-blocker-induced cardiodepression. Furthermore, the effects of two different doses of intravenous glucagon on hemodynamic parameters are explored.
