introduction: the adaptive neuro-fuzzy inference system (anfis) is a soft computing model based on neural network precision and fuzzy decision-making advantages, which can highly facilitate diagnostic modeling. in this study we used this model in breast cancer detection. methodology: a set of 1,508 records on cancerous and non-cancerous participant’s risk factors was used.  first, the risk fact...

introduction: diagnostic values reported for ultrasonographic screening of acute appendicitis vary widely and are dependent on the operator’s skill, patient’s gender, weight, etc. the present study aimed to evaluate the effect of operator skill on the diagnostic accuracy of ultrasonography in detection of appendicitis by comparing the results of ultrasonography done by radiologists and emergenc...

introduction: doing chest x ray (cxr) for all trauma patients is not efficient and cost effective due to its low diagnostic value. the present study was designed aiming to evaluate the diagnostic accuracy of thoracic injury rule out criteria (tirc) in prediction of traumatic intra-thoracic injuries and need for cxr.  method: the present study is a prospective cross-sectional study that has been...

prediction of the outcome and severity of acute upper gastrointestinal bleeding (ugib) has significant importance in patient care, disposition, and determining the need for emergent endoscopy. recent international recommendations endorse using scoring systems for management of non-variceal ugib patients. to date, different scoring systems have been developed for predicting the risk of 30-day mo...

introduction: stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. there are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. in the present study, the accuracy of cincinnati pre-hospital stroke scale was asses...

introduction: acute coronary syndrome accounts for more than 15% of the chest pains. recently, hess et al. developed north american chest pain rule (nacpr) to identify very low-risk patients who can be safely discharged from emergency department (ed). the present study aimed to validate this rule in eds of two academic hospitals. methods: a prospective diagnostic accuracy study was conducted on...

introduction: awareness about the outcome of trauma patients in the emergency department (ed) has become a topic of interest. accordingly, the present study aimed to compare the rapid trauma score (rts) and worthing physiological scoring system (wpss) in predicting in-hospital mortality and poor outcome of trauma patients. methods: in this comparative study trauma patients brought to five eds i...

conclusions adding low dose of ribavirin to peg ifn alfa-2a for treatment of chronic hepatitis c patients with genotype-1 was “highly cost effective” and in patients with low viral load and in previous monotherapy resistant patients was “cost effective.” results the incremental cost effectiveness ratio (icer) for combination therapy in genotype-1 and genotypes non-1 subgroups was 2,673 and 19,2...

introduction: to date, many prognostic models have been proposed to predict the outcome of patients with traumatic brain injuries. external validation of these models in different populations is of great importance for their generalization. the present study was designed, aiming to determine the value of crash prognostic model in prediction of 14-day mortality (14-dm) and 6-month unfavorable ou...
