Abstract
Introduction: The objective of this study is to clarify the opinions of scientific board members of Sina university hospital about medical research and the ways of promoting these researches. Materials and Methods: This is a grounded theory study in which we used in-depth interviews and focus group discussions. Scientific board members and different authorities of the hospital such as the chief of hospital and the deputy of education were participated in the study. We used three different FGDs. Each group included about 5 people. We also interviewed the chief, the deputy of education and the head of clinical research center of the hospital. Results: Most of the participants in our FGDs believed that the most important factor for research promotion in the hospital was preparation of a data base of patients. They also mentioned that, different research workshops are important for empowering scientific board members in research. Conclusion: According to our study the most important strategies for research promotion in Sina hospital are data bank preparation, providing repeated research workshops, revising the bureaucratic process of proposal approvals, revising the manner of evaluation of scientific board members and more participation of the department of epidemiology in clinical researches

Abstract
Background: In recent years, increasingly antibiotic resistance problem among Klebsiella isolates and side effects of antibiotics overuse have made researchers to study the antimicrobial activity of medicinal plants. The aim of this study was to study the inhibitory effect of ethanolic and aqueous extract of Vaccinium arctostaphylos on ESBLs producing Klebsiella strains.
Materials and Methods: Among 143 isolates of Klebsiella collected from some hospitals and clinical laboratories in Karaj, ESBLs producer were screened by phenotypic confirmatory test (PCT). One of them was identified based on 16S rRNA gene sequencing. MIC and MBC of ethanol and aqueous extracts of Vaccinium arctostaphylos were determined using microdilution method on selected ESBLs producing Klebsiella strains.
Results: Resistance to ceftazidime, ceftriaxon and cefotaxime was observed in 14.7% of the isolates. 32 isolates (22%) were detected as ESBL producers. Results of MIC and MBC tests showed that ethanolic and aqueous extract of Vaccinium arctostaphylos have inhibitory effect on ESBLs producing Klebsiella strains,
Conclusion: The presence of antibacterial activity could be confirmed in most plant species used in traditional medicine in Iran and we should focus on combining traditional medicines and modern drugs.

Abstract
Background and Aim: In recent years, Multidrug resistance has been increasing among Klebsiella isolates. The aim of this study was to survey existence of integrons and its relation with antibiotic resistance among clinical isolates of Klebsiella.
Materials and Methods: From Jun 2015 to May 2016, 129 Klebsiella isolates collected from Karaj hospitals and laboratories. Statistical population included 80.6% female and 19.4% male. Antimicrobial susceptibility was performed using Kirby-Bauer disk diffusion and ESBLs producer were screened. Integrons were detected using PCR.
Ethical Considerations: This study with research ethics code IR.IAU.K.REC.1396.16 has been approved by research ethics committee at Islamic Azad University of Karaj, Iran.
Findings: The highest and lowest percentage of sensivity were found to ofloxacin (89.1%) and amoxcicillin (6.2%), respectively. 82.9% of isolates were resistant to more than two antibiotics from different classes. Among 129 isolates, 19.3% of the isolates harbour integrons. Frequencies of MDR among integron-positive isolates were 100%. Also, 71.3% and 28.7% of isolates were ESBLs positive and negative respectively.
Conclusion: Results showed integron elements were prevalent among MDR isolates. Integron-associated resistance genes can be served as reservoirs of multi drug resistance within clinical isolates and presence of integron can be used as a marker to identify MDR isolates. Prevalence of ESBLs among clinical isolates of Klebsiella showed that antibiotics like ampicillin or amoxicillin-clavulanic acid are not effecvtive anymore in treatment of UTIs.

Abstract
Background and Aim: Phonological awareness skills, as part of phonological processing abilities, can predict the extent of success in acquiring written and reading skills. Phonological awareness skills are of concern in children with severe and profound hearing loss, which has been less studied in this population. Thus, this study aimed to evaluate these skills in Cochlear-Implanted (CI) children and compare them with their healthy counterparts.
Methods & Materials: The study population included 25 CI children and 25 healthy children, aged 4-6 years, who were monolingual Persian speakers. The selected CI and healthy children were selected from the Rehabilitation Center of Naqmeh and the Kindergartens in Mashhad, City, Iran, respectively. After selecting each participant, the test of phonological awareness was administered. To compare the mean scores of each subtest, the obtained data were analyzed in SPSS v. 21 using the Mann-Whitney U test.
Ethical Considerations: This study was approved by the Research Ethics Committee of Mashhad University of Medical Sciences (Code: IR.MUMS.REC.1396.263).
Results: The mean scores of CI children were significantly lower than that of their healthy peers in all phonological awareness subscales (P<0.05).
Conclusion: The obtained data suggested that healthy children presented better performance than the CI children in the phonological awareness test. Poor phonological awareness skills in CI children seem to be associated with hearing deprivation before cochlear implantation; thus, it requires to speed up surgery at an early age and the implementation of an effective rehabilitation program.

Abstract
Background and Aim: Topical supplements and vitamins have often been used to accelerate the healing of burn wounds. This study investigated the effects of topical application of vitamin C solution on burn wounds.
Methods & Materials: This research was performed on 30 patients with extensive second-degree burns on one or two organs with similar burns. The study subjects were randomly divided into the intervention and control groups. The intervention group received topical application of vitamin C solution in addition to silver sulfadiazine ointment in the burn area; however, only silver sulfadiazine ointment was applied in the burn area in the control group. The wounds were examined and scored on days 1, 3, 7, and 14 using the Bates-Jensen Wound Assessment Tool. The collected data were analyzed in SPSS using repeated-measures Analysis of Variance (ANOVA).
Ethical Considerations: This study was approved by the ethics committee of sabzevar university medical sciences. (Code: IR.MEDSAB.REC.1394.60).
Results Eighteen of the 30 examined patients were male and 12 were female. Their Mean±SD age and body mass index were 43.03±11.90 years and 27.82±4.08 kg/m2, respectively.
Conclusion: The repeated-measures ANOVA data indicated that the study groups were significantly different concerning the final mean scores given to the wounds (P=0.047). In other words, the research groups significantly differed in wound healing; thus, topical application of vitamin C significantly improved wound healing in the study participants.
