background nosocomial infections increase mortality rate in neonates. studies have attributed the use of h2 blockers as one of the various factors that increase the risk of nosocomial infections. objectives to define the relationship between nosocomial infection and ranitidine in very low birth weight (vlbw) infants admitted in the nicu of a tertiary care hospital. patients and methods all vlbw...

the objective of the study was to evaluate the position of patient education measuring knowledge, attitude, and practice (kap) among health care workers (hcws). it is also aimed to emphasize the need for a real position for patient education. this survey was performed among a group of hcws in iran. the scores had an acceptable level. however, nurses, females and younger people received higher s...

abstract increase in aquatics demand is one of the major goals for production policies. hence analysis of demand structure and aquatics consumption patterns is very applicative and useful for policy makers. using the almost ideal demand system (a.i.d.s), the demand function for types of aquatics and chicken meat in urban and rural societies in kerman city were estimated. applying time series da...

background: red blood cell and other blood products play a crucial role in management of different disease processes, but in spite of implementation of crucial steps to improve the process of request for blood and blood consumption, there is still not enough information available regarding the proper practice in many medical centres. we aimed to evaluate the status of blood product requests and...

component-resolved  diagnosis (crd) using microarray technology has recently been introduced  with the  aim to  improve diagnosis of allergy. the  aim of this study was to compare performance of this allergen microarray to those of an established extract-based skin prick testing (spt). 45  patients  with  allergic rhinitis  were studied  (16 children  and  29  adults). spt  to dermatophagoides ...

Researchers sometimes aggregate data, such as combining resident data into state-level means. Doing so can sometimes cause valid individual-level data to be invalid at the group level. We focus on cross-race misaggregation, which can occur when individual-level data are confounded with race. We discuss such misaggregation in the context of Simpson’s Paradox and identify four diagnostic indicato...

We discuss the possible detection of a stochastic background of massive, nonrelativistic scalar particles, through the cross correlation of the two LIGO interferometers in the initial, enhanced and advanced configuration. If the frequency corresponding to the mass of the scalar field lies in the detector sensitivity band, and the non-relativistic branch of the spectrum gives a significant contr...
