BACKGROUND AND OBJECTIVE Acinetobacter baumannii is an aerobic non-motile Gram-negative bacterial pathogen that is resistant to most antibiotics. Carbapenems are the most common antibiotics for the treatment of infections caused by this pathogen. Mechanisms of antibiotic-resistance in A. baumannii are mainly mediated by efflux pumps-lactamases. The aim of(More)
Among numerous artificial intelligence approaches, k-Nearest Neighbor algorithms, genetic algorithms, and artificial neural networks are considered as the most common and effective methods in classification problems in numerous studies. In the present study, the results of the implementation of a novel hybrid feature selection-classification model using the(More)
BACKGROUND Fairness in financial contribution for health was determined by WHO (World Health Report, 2000) as the third goal of health systems which is measured by fairness in financial contribution index (FFCI). The aim of this study was to estimate FFCI and quantify extent of catastrophic household heath expenditures. METHODS We conducted a descriptive(More)
BACKGROUND Cytomegalovirus (CMV), a problematic virus in solid organ transplant recipients (SOTR) such as liver, can worsen overall mortality and transplant outcome, so its prevention and treatment is a key of success in such patients. This study is aimed to compare the efficacy of ganciclovir (GCV) and valganciclovir (VGC) for prevention and treatment of(More)
BACKGROUND Few studies have addressed the secular trend of malignancies in developing countries such as Iran. This study aimed to determine the trend in the incidence of gastrointestinal cancers during a period of 15 years in Kermanshah, Iran. METHODS All of the confirmed positive pathologic reports for esophageal, gastric and colorectal cancers from 1993(More)
BACKGROUND The main sources of radiation exposure of all living organisms including humans are natural. In fact, radon and its decay products are the cause of 50% of the total dose that is derived from natural sources. Because of the significant health hazards of radon gas, its levels are widely monitored throughout the world. Accordingly, considerable(More)
The classification of Acute Coronary Syndrome (ACS), using artificial intelligence (AI), has recently drawn the attention of the medical researchers. Using this approach, patients with myocardial infarction can be differentiated from those with unstable angina. The present study aims to develop an integrated model, based on the feature selection and(More)
OBJECTIVE Based on findings of previous studies, those men on Methadone Maintenance Therapy (MMT) have a high prevalence of Erectile Dysfunction(ED), related to hypogonadism and depression. We conducted this study to evaluate the efficacy of Trazodone (an antidepressant which can improve sexual function) on this sexual dysfunction. METHOD A structured(More)
INTRODUCTION Prenatal exposure to maternal anxiety and inappropriate levels of glucocorticoids may influence intrauterine growth and affect later health outcomes. We examined the relationship between maternal anxiety, maternal serum, and fetal cord blood cortisol. METHODS Eighty-four pregnant women with gestational age above 37 weeks admitted for elective(More)
BACKGROUND The aim of this study was to investigate the trends in mortality from road traffic accidents (RTA) in Fars Province, southern Iran. METHODS The Age and sex-standardized mortality rate attributed to RTA from 2004 to 2010 in Fars Province was calculated using world standard population. We also used linear regression and chi-squared tests. (More)
