Filter by:This study focuses on the genetics and metabolism of Donnai-Barrow Syndrome (DBS).
The aim is to evaluate the effect of treatment with Continuous Positive Airway Pressure (CPAP) device on clinic and ambulatory blood pressures (BP) of 200 resistant hypertensive patients with moderate-severe obstructive sleep apnea syndrome (OSAS).
The purpose of this study is to compare two different physical therapy exercise programs in persons who have shoulder pain in order to determine if they have a different affect on pain level and ability to use the injured shoulder after treatment. Both exercise groups will attend physical therapy for an hour,two to three times a week, for eight weeks. The first two weeks of therapy sessions will involve learning the exercises and testing to determine what weight to use during exercises. One group will perform a traditional therapy exercise program for shoulders using hand weights. The other group will perform a version of the same shoulder exercises but with a different exercise technique. Exercises in both programs are part of the standard of care for shoulder impingement in physical therapy but one program concentrates on the lowering portion of the exercise (eccentrics) while the other emphasizes the lifting portion of the exercise (concentrics). Both groups will perform the same warm-up, stretching, and cool-down exercises. Participants will also be required to perform a daily home exercise program of stretches and range of motion that will take about 20 minutes to complete. Exercise testing will determine the hand weight resistance used by each person during their therapy sessions and re-testing will occur every two weeks to determine any changes in the weight used for the exercises to keep them challenging. Pain level, ability to use the injured arm for daily activities, strength, and amount of movement in the shoulder, will be measured at the start of physical therapy and after five and eight weeks (end of study) of the exercise treatments. A concurrent study investigating the reliability of the shoulder motion and strength measurements used in the larger study will also be performed. Research hypotheses: 1. Adults with shoulder pain who complete the eccentric progressive resistive exercise intervention will demonstrate significantly greater improvements in the outcome measures at three weeks, earlier in the intervention, than the concentric progressive resistive exercise intervention group. 2. Adults with shoulder pain who perform progressive resistive exercise interventions, regardless of contraction type, will demonstrate significant improvement in the shoulder outcome measures at three and six weeks of intervention.
This extension study of HGT-HIT-045 is designed to collect long-term safety data in pediatric participants with Hunter syndrome and cognitive impairment who are receiving intrathecal (IT) idursulfase-IT and intravenous (IV) Elaprase enzyme replacement therapy.
The purpose of this study is to Evaluate the Optimal Dosage of Mosapride (Medirac) and Probitics in Irritable Bowel Syndrome Without Predominant Diarrhea.
To evaluate the safety and tolerability of ascending doses of subretinal injections of SAR421869 in participants with Usher syndrome type 1B. To evaluate for possible biological activity of SAR421869.
Patients with a low blood count (anemia) with stable or unstable coronary artery disease consistently show worse clinical outcomes. It is unclear whether this association is confounded since anemic patients tend to be also sicker i.e. have lower ejection fractions or more comorbidities and this would be the reason for the worse outcomes rather than anemia. The coronary arteries are a unique vascular bed insofar that across the cardiac circulation oxygen extraction is close to maximal at rest. Thus increases in demand can only be met by increases in blood flow and hemoglobin concentration since oxygen extraction is maximal at rest. It is natural to assume that maximization of oxygen delivery in the setting of active coronary syndrome (ACS) is beneficial to the patient since oxygen extraction and coronary blood flow is fixed. In fact, in most intensive care units patients with ACS are transfused to a HCT of 30%. However, retrospective analysis of trial data showed at best mixed results in clinical outcome when patients with ACS were transfused and in fact in some studies showed consistently worse outcomes than non-transfused patients. Similar disappointing results have recently published in patient who underwent coronary artery bypass grafting (CABG). This study is designed to determine the effect of red blood cell (RBC) transfusion on oxygen consumption, cardiac, microcirculatory and endothelial function in patients with active coronary artery disease. For this study active coronary artery disease will be defined as the patient having undergone within the past 4 days of recruitment either a myocardial infarction due to atherothrombosis (AHA type I myocardial infarction) or surgery for coronary artery bypass grafting. In specific this study will test the hypothesis whether RBC transfusions improves cardiac and vascular function in patients with a hematocrit of less than 30% with active coronary artery disease. Aims of this study are to determine whether RBC transfusion in patients with active coronary artery disease and anemia: - increases oxygen delivery to the peripheral tissues. - increases whole-body oxygen consumption. - decreases nitric oxide bioavailability, endothelial, microcirculatory, and myocardial function, and/or increases platelet aggregation
Background: The evaluation for hypercortisolism includes an overnight 1mg dexamethasone (DXM) suppression test. An important shortcoming is the diagnostic specificity of only 80%, which is likely due to inter-individual differences in gut absorption or metabolism of DXM. Study hypothesis: The investigators hypothesize that serum-DXM measurements will increase the diagnostic accuracy of the overnight DXM-test in the work-up of hypercortisolism. Aims: The primary aim of this prospective study is to evaluate if serum-DXM measured simultaneously with serum-cortisol in morning samples could increase the diagnostic accuracy this diagnostic test. There are several secondary aims. One is to estimate the prevalence and causes of unusual DXM absorption or metabolism. The investigators will also evaluate the feasibility and diagnostic accuracy of salivary DXM. Moreover, the diagnostic accuracy of midnight salivary cortisol and cortisone, and urinary cortisol, will be evaluated and compared. Design: Levels of DXM in morning serum following an overnight DXM-test will be analyzed in patients under evaluation for hypercortisolism (including incidentalomas). A cut-off level to identify inadequate DXM concentrations in serum to suppress endogenous cortisol production will be established based on the negative tests. This cut-off level will then be applied in a retrospective analysis of the diagnostic accuracy of DXM-tests. This prospective study has a blinded design as the DXM measurements are disclosed after the end of the trial.
Polycystic ovary syndrome affects a striking 9-18% of Australian reproductive aged women and has been associated with a number of metabolic abnormalities. Given the strong correlation between metabolic abnormalities and increased sympathetic activity, we hypothesise that reducing this activity using medication (moxonidine) can help improve the metabolic abnormalities, and therefore improve outcomes in polycystic ovary syndrome.
Patellar subluxation is a common disorder that may cause patellofemoral pain syndrome. The efficiency of patellar taping in the treatment of patellofemoral pain syndrome has been reported good outcomes in most patients. However, some studies reported less effective in patients with higher body mass index, larger lateral patellofemoral angle, and smaller Q angle. The investigators hypothesized that femoral internal rotation is a negative factor to the patellar taping. The investigators enroll consecutive 100 patients with anterior knee pain and radiographic evidence of patellar subluxation. The investigators determine femoral rotation via physical examination. The visual analogue scale was evaluate to compare the result between the those with and without femoral internal rotation.
