unfortunately, the prevalence of cesarean section has increased in recent years. whereas awareness of the prevalence and causes is inevitable for planning and effective interventions, so aim of this study has designed and conducted for reviewing of systematic prevalence and caesarean causes in iran. in this meta-analysis, the required information have been collected using several keywords which...

background and aims: thyroid cancer is the most common endocrine malignant and papillary cancer and three times more prevalent in women than men. the aim of this study was to evaluate the incidence rate and trend of thyroid cancer in iranian population. methods: national incidence was rated by iran national cancer registry data derived from iran’s annual national cancer registration reported fr...

Objective: Nowadays the value of bioelectrical impedance analysis (BIA) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. The current study determine accuracy of BIA compared with body mass index (BMI) measurement for estimating body composition in a group of normal weight employee women with a sedenta...

The impact of a positive fluid balance on morbidity and mortality has been well established. However, little is known about how to monitor fluid status and fluid overload. This narrative review summarises the recent literature and discusses the different parameters related to bio-electrical impedance analysis (BIA) and how they might be used to guide fluid management in critically ill patients....

this paper presents an economic evaluation of gas to liquids (gtl) project using “south-pars” gas field of iran based on the latest actual performing gtl projects. iran has the world’s largest reserves of natural gas and can satisfy the projected long-term market demand of gtl products which have lower pollution and higher quality than refinery products. the results of cost-benefit analysis sho...

The objectives of the present study were to describe and compare the body composition variables determined by bioelectrical impedance (BIA) and the deuterium dilution method (DDM), to identify possible correlations and agreement between the two methods, and to construct a linear regression model including anthropometric measures. Obese adolescents were evaluated by anthropometric measures, and ...

To estimate more accurately the beef marbling score (BMS) of live beef cattle, the Bayesian network model (BNM) could be used in parallel with other developed methods, such as ultrasound (US) image analysis with a neural network (NN), biological impedance analysis (BIA) and visual inspections of an experienced inspector. Additionally, most of these methods individually represents positive trend...

OBJECTIVES Management of hyponatraemia depends crucially on accurate determination of volaemic (hydration) status but this is notoriously challenging to measure in older people. Bioelectrical impedance analysis (BIA) provides a validated means of determining total body water (TBW), but its clinical utility in determining volaemic status in hyponatraemia has never been tested. This study assesse...
