Filter by:The metabolic syndrome may be defined as the constellation of cardiovascular disease (CVD) risk factors that comprises obesity, type 2 diabetes, dyslipidemia, and hypertension. Lack of habitual physical activity and certain dietary patterns, including high-saturated fatty acids (SFA) intake, contribute to increase the risk of CVD, whereas the greatest risk reduction is related with monounsaturated fatty acids (MUFA), mainly from olive oil, and omega-3 polyunsaturated fatty acids (PUFA). Vitamin B3, as a major substrate for nicotinamide phosphoribosyltransferase (NAMPT), has also emerged as a nutritional intervention strategy for prevention of CVD. NAMPT has been shown to exert activities of central importance to cellular energetics and innate immunity. Within the cell, NAMPT is the rate-limiting step in a salvage pathway of nicotinamide adenine dinucleotide (NAD+) biosynthesis. By virtue of this role, it can regulate cellular levels of NAD+ and thereby NAD+-consuming enzymes. NAMPT is also released by a variety of cells, and elevated levels can be found in the systemic circulation of subjects with a range of inflammatory disorders. Recent evidences suggest that, primarily due to its high MUFA content, olive oil is useful as an optimal fat for the modulation of CVD risk factors in the postprandial state. In addition, NAMPT has been shown to correlate with triglycerides in the fasting plasma, and a potential regulatory role for fatty acids on NAMPT expression has been proposed. The global aim of the project is to assess whether olive oil (MUFA), compared to other dietary fatty acids (SFA and omega-3 PUFA) and in association with vitamin B3 could have benefits on NAMPT-related inflammation and atherosclerosis. We hope to provide important novel insights on the relationship among dietary fatty acids, NAD+ metabolism, and metabolic syndrome. This aim is expected to be achieved in one principal objective: To elucidate the influence of olive oil (MUFA), butter (SFA) or fish oil (omega-3 PUFA) meals supplemented by vitamin B3 on postprandial NAMPT modulation and its involvement on leukocyte inflammatory response in subjects with metabolic syndrome.
The Trial Objective is to assess safety and efficacy of oral fingolimod (FTY720) in children older than 6 years with Rett Syndrome. So far there is no established treatment for children with Rett Syndrome. Therefore a positive result in terms of safety and first indications of efficacy would path the way to a phase II clinical study with more patients to further test the hypothesis that fingolimod treatment may slow down the regression of motor and language skills.
This study demonstrates the effect of generic clopidogrel bisulfate (Plavitor®) in comparison with the original clopidogrel bisulfate (Plavix®) in patients with acute coronary syndrome.
Hypothesis: High sensitivity cTnI assays will have improved diagnostic accuracy for type 1 MI compared to contemporary cTnI assays. The primary objective of the study is to determine the performance of a high sensitivity cardiac troponin I (hs-cTnI) assay compared to a contemporary cTnI assay for the diagnostic accuracy of type 1 acute myocardial infarction (AMI). The diagnostic performance of Abbott's hs-cTnI assay will be evaluated. Investigators will assess the assay's ability to diagnose AMI earlier and to rule out AMI earlier. The sensitivity, specificity, positive predictive value and negative predictive value of the hs-cTnI assay will be evaluated with both a universal cut off as well as with gender and potentially age derived 99th percentile upper reference limits (URL). Investigators will evaluate delta hs-cTnI values (pre-specified absolute concentration and percent changes over time) for their ability to contribute to the negative predictive value and hence potentially lead to an earlier rule out of AMI (improved specificity). Additionally, investigators will assess delta changes of the hs-cTnI assay for their potential contribution to the clinical differentiation of type 1 and type 2 (supply demand mismatch) MIs. Lastly, investigators will compare the diagnosis of AMI based on the currently used contemporary assay to the hs-assay, to assess both the incidence of AMI as well as for the time to diagnosis.
Sanfilippo syndrome Type A, or Mucopolysaccharidosis (MPS) IIIA, is a rare lysosomal storage disease caused by deficiency of the enzyme heparan N-sulfatase (sulfamidase). In the absence of this enzyme, there is an accumulation of the glycosaminoglycan, heparan sulfate, resulting in progressive neurodegeneration. Symptoms are usually first noted in the 1st or 2nd year of life, although definitive diagnosis is often delayed, with an average age of diagnosis of 4.5 years. The disease is characterized by developmental delays initially, followed by neurological developmental arrest, then regression. These developmental deficits are typically associated with severe behavioral disturbances. Patients have a significantly reduced lifespan, with few surviving beyond the 2nd or 3rd decade. The purpose of this study is to evaluate the safety and efficacy of recombinant human heparan-N-sulfatase (rhHNS) in pediatric patients with Early Stage Mucopolysaccharidosis Type III A Disease.
In the era of hypomethylating agent in MDS treatment, the investigators aimed to investigate the prognostic impact of mutations in spliceosome machinery genes (SRSF2, U2AF1, and ZRSR2) on the outcomes of 1st line decitabine treatment in MDS.
Compared to other children, those with disability have additional challenges to being physically active. Prader-Willi Syndrome (PWS) is a genetic form of childhood obesity that is characterized by hypotonia, growth hormone deficiency, behavioral, and cognitive disability. In children, the low prevalence of PWS (1 in 10,000 to 15,000 live births) makes group-based physical activity (PA) interventions impossible. In contrast, the home environment presents a natural venue to establish a PA routine for this population. The present high prevalence of non-syndromal childhood obesity (one in four) and high physical inactivity rates, make alternative approaches to increasing PA in this population an area of high interest. Therefore, we have developed a 24-week home-based physical activity that could be suitable for children and adolescents ages 8-15 with PWS as well as obese children without PWS ages 8-11 years. It is hypothesized that: 1) an age-appropriate 24-week home-based PA intervention will increase PA levels in youth with PWS and without the syndrome but with obesity; 2) motor proficiency, central sensory reception and integration, and body composition will significantly improve in youth with and without PWS following completion of the home-based PA intervention and 3) physical activity self-efficacy and quality of life will increase significantly in youth with and without PWS who complete the home-based PA intervention. The study participants are 115 youth ages 8-15 y (45 with PWS and 70 without PWS but categorized as obese). The study utilizes a parallel design with the wait-listed control group receiving the intervention after serving as control. Participants are expected to complete the PA curriculum 4 days a week for six months including playground games 2 days a week and interactive console games 2 days a week. Parents are trained at baseline and then provided with a PA curriculum (Active Play at Home) and equipment to guide their implementation of the program at home. Measurements of children and parent dyads are assessed at baseline and at the end (week 24) of the intervention or control periods. Outcome measures include PA, body composition, motor proficiency, central sensory reception and integration (subsample of children only), quality of life and physical activity self-efficacy. PA intervention compliance is monitored using mail-in daily self-report checklists.
The study is a randomized, double-blind, placebo-controlled study in children with Alagille Syndrome (ALGS). The study will investigate the effects of LUM001, compared to placebo, on pruritus, serum bile acids, liver enzymes, and other biochemical markers in patients with ALGS.
The purpose of this study is to determine the effectiveness of the HEART Pathway, a clinical decision aid for the care of patients with chest pain, in a "real-world" clinical setting. This will be accomplished through the building of a transformative collaboration between research, education, and health systems operations to more effectively and efficiently provide patient care.
The purpose of this study is to evaluate the effectiveness and safety of deep brain stimulation (DBS) as a possible new treatment for Tourette Syndrome (TS). This investigation will (1) test the hypothesis that centromedian (CM) continuous brain stimulation will be an effective, safe method for the treatment of tics in medication refractory TS, (2) will define the intra-operative and post-operative physiological changes, and (3) will test the hypothesis that responsive brain stimulation (RBS) will provide an alternative to chronic DBS in TS.
