Filter by:Participants will be randomly assigned in one of two groups. Group A: oral supplementation with 4,000 IU of vitamin D (cholecalciferol). Group B: oral supplementation with 400 IU of vitamin D (cholecalciferol). Both treatments will be consumed daily for 6 months. Outcomes will be evaluated at baseline, three and six months. Variables related to leptin resistance will be evaluated. The main hypothesis is that vitamin D will diminish leptin resistance in overweight and obese women. If the hypothesis is confirmed, women will show a reduction in the Resting energy expenditure: serum Leptin ratio (REE: Leptin ratio), as well as a reduction of hunger, body weight, body and abdominal fat and an increase in resting energy expenditure.
Gestational diabetes mellitus (DM) is one of the most frequent complications in pregnant patients with polycystic ovary syndrome (PCOS) in 20-40% of cases and ~40% of patients with gestational DM are likely to have underlying polycystic ovarian morphology. A recent meta-analysis demonstrated a significantly higher risk of developing gestational DM [odds ratio (OR) 2.94; 95% confidence interval (CI): 1.70-5.08] in the PCOS population. Metformin is an oral biguanide insulin sensitizer used for treating type-2 DM and recently introduced to treat PCOS. At the moment, preliminary data seem to reassure regarding the use of metformin in PCOS patients showing benefits for maternal and fetal outcomes, without serious adverse events. Furthermore, well-designed randomized, controlled trials (RCTs) on this issue are lacking, thus it is not possible to either suggest or advice against the use of metformin during pregnancy for reducing gestational DM risk. To this regard, PCOS represents an intriguing model of "high-risk patients" to evaluate the efficacy of metformin for preventing DM development. The present protocol firstly will evaluate the effects of metformin administration in reducing incidence of gestational DM in high-risk patients, such as pregnant PCOS patients.
The aim of this study is to investigate whether there was an association between obesity and periodontitis, tendency to caries and periapical lesions. People who have a higher body mass index produce cytokines (hormone-like proteins), that lead to systemic/chronic inflammation (like periodontitis and periapical lesions), and obesity related dietary habits could result in an increment of dental caries because both the amount and the frequency of sucrose ingestion are important factors associated with the aetiology of the oral disease.
The purpose of this study is to assess the prevalence of overweight and obesity in children attending special primary education and to evaluate the effects of a multidisciplinary school-based lifestyle intervention.
