By improving glycemic control, many of the devastating complications of diabetes are to a large extent preventable. The use of a low GI (glycemic index) diet to improve glycemic control is relatively new and untested. However, a low GI diet may be a cost-effective approach to preventing diabetes-related complications. The aim of this proposed 2-year study is to gather pilot data on the feasibility of implementing a nutritionist-delivered low GI intervention, to reduce dietary GI in patients with type 2 diabetes, and to compare it with a nutritionist-delivered standard American Diabetes Association (ADA) diet intervention. Our outcomes are recruitment and retention rates, as well as physiological measures (HbA1c, blood lipids, blood pressure, and body mass index), dietary GI scores and acceptability of the intervention. Primary hypotheses: 1\. Recruitment and retention rates for the low GI intervention will be satisfactory. Secondary hypotheses: 1. Participants in the low GI intervention group will show more favorable changes in physiological measures than participants in the ADA diet group. 2. Participants in the low GI group will be successful in lowering the GI of their diet. 3. Participants will find the intervention acceptable.
NCT01602926
Hallux valgus is a common deformity of the big toe, defined as medial deviation of the first metatarsal bone along with lateral deviation of the first toe. Surgery has been shown to be beneficial when compared to orthotics or no treatment. While generally effective, surgery is associated with significant post-operative pain and disability, with several weeks of limited mobility. Minimally invasive techniques have the potential to lead to increased patient satisfaction while still achieving adequate correction of the deformity. This trial is a non-inferiority treatment study, with open-label, randomized, prospective, controlled, parallel experimental design, to compare the clinical and radiographic outcomes of a minimally invasive surgery versus a conventional surgery for hallux valgus. This trial examines two different surgical interventions. No drug or device is being evaluated in this trial. 60 to 100 patients, over the age of 18 years, undergoing surgical correction of mild to moderate hallux valgus will be enrolled in the trial. The patients will be randomized to two groups, one treated with a conventional distal osteotomy surgery, the other treated with a minimally invasive surgery. Randomization will occur immediately prior to surgery via a multitude of opaque envelopes containing a coded group assignment. Due to the differences in the techniques, neither the investigator and the subject can be effectively blinded to the group assignment. Data collection for the outcomes measures will occur preop, and then post of at 2 weeks, 12 weeks, and at 1,2, and 3 years. The primary outcomes measure is the Manchester-Oxford Foot Questionnaire Score (MOXFQ). Manchester-Oxford Foot Questionnaire' (MOXFQ), a 16 item patient-reported questionnaire consisting of three domains/scales: 'Walking/standing' (seven items), 'Pain' (five items) and 'Social interaction' (four items). The MOXFQ is a validated disease-specific outcomes scale for foot and ankle surgery which has been shown to be responsive and reliable. Secondary outcome measures are preoperative to postoperative change in hallux valgus angle (HVA). Radiographic outcomes parameters will be measured using weight-bearing radiographs to analyze preoperative and postoperative hallux valgus angle, and the correction or normalization thereof. (Degrees of correction = 2 week preoperative HVA - 12 week postoperative HVA.)
