Filter by:The investigators propose that the sensitivity to glucagon in hepatic lipid metabolism is impaired in subjects with non-alcoholic fatty liver disease (NAFLD) and steatohepatitis (NASH). Moreover, they propose a dys-coordinated, reduced glucagon sensitivity in hepatic lipid metabolism and endogen glucose production in patients with NAFLD and NASH compared with healthy subjects and patients with simple steatosis. This reduced sensitivity may be the basis of a more severe dyslipidemia and the production of increased concentrations of toxic lipid intermediates in plasma and muscle tissue. The study will include healthy subjects with obesity and subjects with simple steatosis and NASH, tested at basal glucagonemia and moderate hyperglucagonemia to mimic insulin resistant levels during simultaneous somatostatin infusion and replacement doses of insulin and growth hormone. Infusion of palmitate, VLDL-triglyceride and glucose tracers in combination with indirect calorimetry as well as skeletal and adipose tissue biopsies will be employed to assess free fatty acid and VLDL-triglyceride kinetics (turnover, and oxidation) and hepatic fatty acid-esterification.
This is a Phase II, Randomized, Blinded, Sham Procedure-Controlled, Parallel-Group Trial to Evaluate the Efficacy, Safety and Tolerability of LYR-210 in Adult Subjects with Chronic Sinusitis.
In an avalanche burial with an air pocket hypercapnia (and hypoxia) develops within few minutes, hypercapnia increases the rate of cooling and therefore the development of hypothermia. The Triple H Syndrome (Hypoxia, Hypercapnia, Hypothermia) occurs. This specific combination of the three parameters is unique for avalanche burial with an air pocket. Every single parameter has a substantial effect on the hemoglobin-oxygen dissociation curve, but until now no study described the combination of these three parameters. This curve will be measured under these specific conditions in a specifically developed in vitro model, to quantify its shifts and to show if there are combined effects of pCO2 and temperature. The newly developed method will be validated in comparison with an established method. The project will be performed with whole blood, drawn by healthy volunteers, in an experimental setting. The samples will be blinded to the investigator and analyzed in a randomized manner.
The goal of this R21 grant is to test the feasibility of a theoretically informed, LGBTQ-affirming intervention (Proud & Empowered; P&E). Although LGBTQ adolescents experience disparities in behavioral health outcomes compared to their heterosexual peers, interventions are scarce. For example, LGBTQ adolescents are 3 to 4 times more likely to meet criteria for an internalizing disorder and 2 to 5 times more likely to meet criteria for externalizing disorders than their heterosexual peers. Our intervention seeks to address disparate behavioral health problems such as depression, anxiety and trauma symptomology. Our goal will be achieved by completing two specific aims: 1) Assess the feasibility, including recruitment, enrollment, fidelity of service delivery, satisfaction, safety, and retention, of the intervention in a randomized control trial with four schools, 2) Obtain preliminary estimates of intervention effects on key behavioral health symptoms for LGBTQ youth and school climate (norms, attitudes, beliefs, behaviors) at the school level in preparation for a larger efficacy trial. This innovative R21 application brings together a team of nationally recognized minority stress and prevention science experts and responds to a nationally established public health need for research from the Institute of Medicine, the National Institutes of Health, and the National Gay and Lesbian Task Force.
Tyrosine kinase inhibitors (TKIs) have improved the survival of patients with metastatic renal cell carcinoma, and are commonly used as first-line option for this condition, but their use is encumbered by side effects, mainly diarrhea, for which there are no standardized strategies. Increasing evidence suggests that gut microbiota could influence the development of TKIs-induced diarrhea. In theory, the therapeutic modulation of gut microbiota could be an approach to alleviate TKI-induced diarrhea. Fecal microbiota transplantation (FMT) is the infusion of fecal microbiota from a healthy donor in the gut of a recipient with the aim of curing a specific disease. It has been increasingly recognized as a highly effective treatment against recurrent Clostridium difficile infection.To date, the effects of FMT on chemotherapy-related diarrhea are unknown. This study will evaluate, through a randomized controlled design, the efficacy of fecal microbiota transplantation (FMT), compared with sham FMT, in treating TKI-induced diarrhea in patients with metastatic renal cell carcinoma.
As the standard of best practice, care of complicated or difficult patient needs not only knowledge but also including skills and clinical thinking in many aspects. Simulation is now accepted as the way of teaching for adult learners. This learning method can help students to apply their knowledge, practical skills and non-technical skills. A systematic review study showed that self-directed learning (SDL) in health professions education is associated with moderate improvement in the knowledge domain. SDL also help the learners to improve self-efficacy and the learning outcomes in complicated tasks.In this study, the investigators wanted to evaluate that simulation can enhance student to do SDL in the both pre and post session period.
This is a Phase 3, multicenter, double-blind, randomized, placebo-controlled study to evaluate the safety and efficacy of iloprost on the frequency of and relief from symptomatic digital ischemic episodes in subjects with systemic sclerosis.
A harmonious family relationship has significant effects on the psychological well-being and development of children. Good communication between parents and children is a crucial element for family health, happiness and harmony. However, communication within Hong Kong families is vastly inadequate partly due to our busy urban lifestyle. The 3Hs Family Drama Project I was to promote health, happiness, harmony (3Hs), healthy eating and physical activity in primary school students. Students watched interactive live drama in schools and were given DVD and worksheets. Students were encouraged to watch the DVD with other family members at home. This study was to evaluate the effectiveness of interactive live drama, DVD and worksheet.
The aim of this study is to determine if machine learning can be used to automatically highlight key anatomy on the ultrasound image to help anaesthetists perform ultrasound-guided regional anaesthesia.
It was a prospective observational study, where preoperative nutritional status and early postoperative complications <30 days (infectious or noninfectious) were studied. The patients admitted between July 2015 to May 2017, who underwent major GI surgeries were included in the study. The study was designed to check if BMI and NRI can predict the postoperative outcomes in these patients.
