Association between and body mass index in healthy subjects; a theoretical pilot study.

Background: is a prevalent protozoan of the gut lumen with worldwide distribution. Recent studies showed that this microorganism may alter both richness and diversity of the gut microbiota. In the current study we assessed the dietary intakes in two -positive and -negative groups to evaluate the impact of this protozoan on the body mass index (BMI) and the dietary intakes.

Advances in the Diagnosis of GERD Using the Esophageal pH Monitoring, Gastro-Esophageal Impedance-pH Monitoring, And Pitfalls.

PH monitoring is not capable of detecting all types of reflux, especially when the amount of acid is very low or not at all in the refluxate. Multichannel intraluminal impedance-pH monitoring (MII-pH) is used as a new method to assess bolus transport. The types of reflexes including acid, weak acid and weak alkaline MII-pH is capable of distinguishing more reflux episodes based upon use of physical and chemical parameters of the refluxate, leads to a diagnosis of normal acid reflux from abnormal nonacidic reflux.

Effect of diet based on the principles of Iranian traditional medicine on cirrhosis (a clinical trial).

Objectives: Cirrhosis is associated with morbidity and mortality worldwide. Iranian traditional medicine (ITM) focused on nutritional intervention in order to improve liver function. The aim of this study was to assess the effectiveness of a diet designed based on ITM and current dietary recommendations.

Epidemiology of gastroesophageal reflux disease in Tehran, Iran.

Background And Aim: Epidemiological studies have indicated an increase in the prevalence of gastroesophageal reflux disease in Western countries; however, there is a lack of information about its prevalence in Iran. The aim of this study was to measure gastroesophageal reflux disease prevalence in a representative sample of the Tehran population in 1999.

Methods: In a cross-sectional study, 700 people, with a male : female ratio of 1:1, were selected by stratified randomization based on the probability of 20% prevalence of gastroesophageal reflux disease and 3% error.
