Abstract
INTRODUCTION Nosocomial infections (NIs) are a major challenge worldwide. Identification of antibiotic resistance pattern extended spectrum beta-lactamases (ESBLs) and carbapenem-resistant Enterobacteriaceae (CRE) were the objectives of this study. METHODS In this cross-sectional study, the antimicrobial susceptibility pattern of bacterial isolates collected from patients with NIs in ICU was determined. Overall, 42 Escherichia coli and Klebsiella pneumoniae isolates from different infection sites were used to determine phenotypic tests of ESBLs, Metallo-β-lactamases (MBLs) and CRE. Detection of ESBLs, MBLs and CRE genes were performed by the polymerase chain reaction (PCR) method. RESULTS From 71 patients with NIs, 103 different bacterial strains were isolated. The most frequently isolated bacteria were E. coli (n = 29; 28.16%), Acinetobacter baumannii (n = 15; 14.56%), and K. pneumoniae (n = 13; 12.26%). Also, the rate of multidrug-resistant (MDR) isolates was 58.25% (60/103). Based on phenotypic confirmation tests, 32 (76.19%) isolates of E. coli and K. pneumoniae produced ESBLs, and 6 (14.28%) isolates were identified as CRE producers. PCR showed the high prevalence of the blaCTX-M (n = 29; 90.62%) in ESBL genes. In addition, blaNDM was detected in 4 (66.66%), blaOXA-23 in 3 (50%), and blaOXA-48 gene in 1 (16.66%) isolates. The blaVIM, blaKPC, and blaIMP genes were not detected in any of the isolates. CONCLUSION The Gram-negative bacteria E. coli, A. baumannii, and K. pneumoniae with high resistance levels were the most common bacteria causing NIs in the ICU. This study for the first time identified blaOXA-11, blaOXA-23, and blaNDM-1 genes in E. coli and K. pneumoniae in Ilam city of Iran.

Abstract
BACKGROUND Research evaluation is a systematic and objective process to measure relevance, efficiency and effectiveness of research activities, and peer review is one of the most important tools for assessing quality of research. The aim of this study was introducing research evaluation indicators based on peer reviewing. METHODS This study was implemented in 4 stages. A list of objective-oriented evaluation indicators were designed in 4 axes, including; governance and leadership, structure, knowledge production and research impact. RESULTS The top 10% medical sciences research centers (RCs) were evaluated based on peer review. Adequate equipment and laboratory instruments, high quality research publication and national or international cooperation were the main strengths in medical sciences RCs and the most important weaknesses included failure to adhere to strategic plans, parallel actions in similar fields, problems in manpower recruitment, knowledge translation & exchange (KTE) in service providers and policy makers' levels. CONCLUSION Peer review evaluation can improve the quality of research.

Abstract
INTRODUCTION Patients with Alzheimer disease (AD) suffer from psychotic symptoms including pain. The current antipsychotic drugs confer limited effectiveness, and hence new strategies are being designed to decrease pain in order to increase antipsychological effectiveness. Vitamin B12 is a safe supplementary drug to decrease pain. Additionally, cytokines participate in the pathogenesis of immune-related diseases such as AD. Thus, the main aim of this clinical trial study was to determine the effects of treatment with risperidone and quetiapine, as antipsychotic drugs, with and without vitamin B12 on the psychotic symptoms of AD patients and the expression of IL-6, IL-8, tumor growth factor (TGF)-β, tumor necrosis factor (TNF)-α, and endothelin (ET)-1). MATERIAL AND METHODS Serum levels of IL-6, IL-8, TGF-β, TNF-α, and ET-1 were evaluated in the following groups: healthy controls, nonpsychotic AD patients, psychotic AD patients, psychotic AD patients under treatment with risperidone, psychotic AD patients under treatment with risperidone plus vitamin B12, psychotic AD patients under treatment with quetiapine, and psychotic AD patients under treatment with quetiapine plus vitamin B12. RESULTS Treatment with antipsychotic drugs plus vitamin B12 led to a decreased expression of IL-8 and TNF-α and an increased expression of TGF-β. Vitamin B12 in association with quetiapine reduced the pain in psychotic AD patients. DISCUSSION Proinflammatory cytokines play important roles in the pathogenesis of psychosis in AD patients. Antipsychotic drugs plus vitamin B12 can reduce and induce the expression of proinflammatory and anti-inflammatory cytokines to improve psychotic symptoms in AD patients.
