Effect of lifestyle modification for two years on obesity and metabolic syndrome components in elementary students: A community- based trial.

Background: Lifestyle modifications, especially improving nutritional patterns and increasing physical activity are the most important factors in preventing obesity and metabolic syndrome in children and adolescents. For this purpose, the following interventional study was designed to investigate the effects of educational programs for students, as well as the changes in diet and physical activity on obesity and components of the metabolic syndrome.

Methods: This study is part of an interventional research project (elementary school) conducted on all students of Sama schools in Zanjan and Abhar in three levels;elementary, middle and high school, including 1000 individuals in Zanjan (intervention group) and 1000 individuals (control group) in Abhar in 2011.

Electrocardiographic Corrected QT (QTc) Dispersion Value as a Predictor for Estimation of Neonatal Mortality in Pre-Term Neonates.

Introduction: Electrocardiographic (ECG) corrected QT (QTc) interval and dispersion were used as prognostic variables in adult patients and limited studies showed the relationship between QTc prolongation and dispersion with some clinical situations in newborn babies.

Aim: In the present study, we compared the electrocardiographic (ECG) variables such as QTc interval and dispersion of healthy full-term and pre-term neonates with those who suffered from non-cardiac illnesses.

Methods: This prospective cohort study involved 127 neonates including four study groups: normal full-term neonates, ill full-term neonates, normal pre-term neonates and ill pre-term neonates.

Early screening of gestational diabetes mellitus using hemoglobin A1C: Revising current screening guidelines.

Background: HbA1C has been a known predictor and diagnostic test for diabetes type 2. However, this test has not yet been widely studied in GDM and more importantly no cutoff point has been defined for HbA1C in GDM. We investigated the efficacy of screening during first and second trimester of pregnancy and defined appropriate cutoff points according to HbA1C and FBS for predicting maternal GDM among women with none to minimal previously known risk factors.

Efficacy of sublingual swallow immunotherapy in children with rye grass pollen allergic rhinitis: a double-blind placebo-controlled study.

Specific local immunotherapy has been recently introduced as an alternative to classic subcutaneous immunotherapy in treatment of allergic rhinitis. In this study, the effects of sublingual immunotherapy (SLIT) on symptoms and medication score and skin prick test evaluation of patients with allergic rhinitis were investigated.In this placebo controlled trial, twenty four patients aged 5-18 years old with grass pollen induced rhinitis and sensitive to rye grass by positive skin prick test received randomly sublingual extract of rye grass or placebo for 6 months.
