Background: Poverty and low socioeconomic status are the most important reasons of increasing the global burden of tuberculosis, not only in developing countries but also in developed countries for particular groups. The purpose of this study was to assess the association between socioeconomic factors and the number of tuberculosis patients using quantile regression for count data.   Me...

Background: Application of growth indicators taken from other countries can cause misdiagnosis of underweight and stunting. In this study we compared the trend of anthropometric growth indicators between the elementary school students of Yazd with the international standards. Methods: The study population of this retrospective cohort study consisted of 591 primary school children in Yazd (285 g...

PURPOSE To report the immediate changes of intraocular (IOP) pressure after an intravitreal injection of 2.5mg (0.1 ml) of bevacizumab. METHODS Prospective, non-controlled, interventional case series of 45 patients undergoing intravitreal injection of 2.5mg (0.1 mL) of bevacizumab for a variety of retinal disorders. IOP was measured with a Goldmann tonometer at baseline, immediately after, 30...

OBJECTIVES There is no agreed-upon definition for severe obesity (Sev-OB) in children. We compared estimates of Sev-OB as defined by different cut-points of body mass index (BMI) from the Centers for Disease Control and Prevention (CDC) or the World Health Organization (WHO) curves and the ability of each set of cut-points to screen for the presence of cardiometabolic risk factors. RESEARCH D...

background: the sensitivity and specificity of body mass index (bmi) percentiles of centers for disease control 2000 (cdc2000) standard was compared with child actual overweight which was identified by fat mass index (fmi) and overweight status in these children based on bmi and fmi. methods: in this case-control study, elementary school girls (aged 8-10 years) were recruited from schools of is...

BACKGROUND A short QT interval, within which an increased risk for atrial fibrillation and/or fatal cardiac arrhythmias occurs, has been difficult to define. METHODS The lower percentiles of a new QTc formula were determined, using a precise mathematical fitting of the QT-heart rate relationship from the ECGs of 13,600 individuals from the NHANES II and III surveys. RESULTS The QTc interval...
