Qualitative and Quantitative Assessment of the Scientific Production of Kerman University of Medical Sciences Academic Members in Scopus Database

Background: The rapid growth of scientific production and the number of researchers has made decision makers think about scientific approaches for evaluation of the researchers’ performance. Scientometric indicators have been introduced to analyze science by quantitative methods. The aim of this study was to evaluate the scientific production of academic members at Kerman University of Medical Sciences (KMU) based on Scientometric indicators. Methods: This was a analytical survey research. The study population was scientific productions of all academic members of KMU until 22nd of August, 2014. Direct search of Scopus Database and checklist were used for data collection. Results: The highest mean (median) of published articles belonged to the Pharmacy School, while the lowest belonged to the Nursing and Midwifery School [17.66(20.50) and 3.08 (0) respectively, (P<0.0001)]. The highest H-Index was 17 and approximately half of the academic members had zero H-indices. A strong positive and significant correlation was found between academic members’ work experience and H-index (r=0.8, P<0.0001).There was also a positive and significant relationship between H-index and academic rank (P<0.0001). Conclusion: The results shows that scientific production of KMU academic members is not significantly different from that of other medical universities of Iran, but it is still far away from global standards. Therefore, policy makers should provide the scientific development requirements through wise planning

A Novel Hybrid Framework for Co-Optimization of Power and Natural Gas Networks Integrated With Emerging Technologies

In a power system with high penetration of renewable power sources, gas-fired units can be considered as a back-up option to improve the balance between generation and consumption in short-term scheduling. Therefore, closer coordination between power and natural gas systems is anticipated. This article presents a novel hybrid information gap decision theory (IGDT)-stochastic cooptimization problem for integrating electricity and natural gas networks to minimize total operation cost with the penetration of wind energy. The proposed model considers not only the uncertainties regarding electrical load demand and wind power output, but also the uncertainties of gas load demands for the residential consumers. The uncertainties of electric load and wind power are handled through a scenario-based approach, and residential gas load uncertainty is handled via IGDT approach with no need for the probability density function. The introduced hybrid model enables the system operator to consider the advantages of both approaches simultaneously. The impact of gas load uncertainty associated with the residential consumers is more significant on the power dispatch of gas-fired plants and power system operation cost since residential gas load demands are prior than gas load demands of gas-fired units. The proposed framework is a bilevel problem that can be reduced to a one-level problem. Also, it can be solved by the implementation of a simple concept without the need for Karush–Kuhn–Tucker conditions. Moreover, emerging flexible energy sources such as the power to gas technology and demand response program are considered in the proposed model for increasing the wind power dispatch, decreasing the total operation cost of the integrated network as well as reducing the effect of system uncertainties on the total operating cost. Numerical results indicate the applicability and effectiveness of the proposed model under different working conditions

Azithromycin versus Cephalexin for Simple Traumatic Wounds in the Emergency Department: A Randomised Trial

Objective: The aim of this study was to investigate efficacy of azithromycin versus cephalexin for infection prophylaxisis in patients with simple traumatic wounds managed at emergency department. Method: This randomized controlled trial compared short-course therapy of once-daily azithromycin (500 mg before the wound repair followed by 250 mg/day for 5 days) with cephalexin (1000 mg before wound repair followed by 250 mg every 6 hours for 5 days) in the treatment of patients with simple traumatic wounds. A total of 366 patients were randomly selected for the study and 303 were evaluated for the final analysis. Results: On completion of therapy, the rate of observed infection was 9.6% in the cephalexin group (15 patients, odds ratio=0.77, 95% confidence interval, 0.56 to 1.06) and 5.4% in the azithromycin group (8 patients, odds ratio 1.42, 95% confidence interval, 0.80 to 2.52). Both treatment indicated similar prophylactic efficacy during the study (P=0.197). Conclusion: Our study showed that Azithromycin as infection prophylaxis in simple traumatic wounds had the same effect as cephalexin but azithromycin is easier to use and more cost-effective compared to cephalexin

Bibliometric and Content Analysis of Scientific Outputs Relevant to Health Education and Promotion in Iran during 1998-2011

Background: Since the aim of health research is to improve the quality of community life, the results obtained from these research could be used in health policies and practices. Therefore, the aim of this study was to evaluate the bibliometric and content analysis of research relevant to health education and promotion performed in Iran during 1998-2011. Methods: This is a descriptive content analysis study. Data were collected from online databases (IranMedex, Medlib, SID, ISI, and PubMed), and all published articles relevant to health education and promotion in Iran up to the end of March 2011 were included in this study. In order to do content analysis a researcher-made checklist approved by experts was used for identifying the variables. Data was entered into SPSS 21 and descriptive statistics and percents were calculated. Results: From 1227 documents retrieved, 817 were published in Persian and 410 in English. A great share of retrieved documents belonged to the articles published in the scientific journals (87.4%). Mental health (10.7%), family planning and reproductive health (10.2 %), and chronic non-communicable diseases (10.2%) were the most frequent subject areas in research relevant to health promotion, respectively. Most of the studies were cross-sectional (52.1%), the most widely used method was simple random sampling (27.7%), and most of the studies were performed locally in provinces (83.7%). Conclusion: Doing more studies by outlining the exact perspective of health promotion research in Iran and comparison of the current status of Iran with that of other countries are recommended

The association between serum 25-hydroxyvitamin D level and recurrent falls in the elderly population: a cohort study

Introduction: Serum vitamin D concentration is a major contributing factor for increasing the risk of fall and fall-related injuries in older adults. However, when prescribed and supplemented for these populations, the outcomes are controversial, and in several cases no improvement has been reported in reducing the risk of recurrent falls. This study aimed to examine the association between serum vitamin D concentration and recurrent falls in Iranian older adults. Methods: This cohort study was conducted in the emergency departments of two university hospitals. A cohort of 82 elderly participants aged over 60 and suffered from an unintentional episode of falling was evaluated six months after their first ED visit. A structured, self-administered checklist was developed to obtain the participants’ demographic and clinical information. Participants also were asked about any recurrent fall experience during follow-up. Results: The mean (SD) age of the study population was 75 (8). Over half of the participants were male (57.3%). The mean (median) serum 25-hydroxyvitamin D (25 (OH)D) concentration was 38 (34) ng/ml. Mean serum 25(OH)D levels varied slightly between gender groups (p=0.450). An inverse but insignificant association was found between the age of participants and their serum 25(OH)D levels (r=-0.03, p=0.7). A small but insignificant association also was found between the mean serum 25(OH)D level and the number of recurrent falls in elderly patients irrespective of their age, gender, or physical activity groups (OR=1.008, p=0.992). Conclusion: In contrast to previous studies, no significant association of serum 25(OH)D concentration was found with recurrent falls in Iranian older adults.

The altered expression of long non-coding RNAs: GHET1, BACE1-AS, PANDA, UCA1 associated with non-small cell lung cancer

Objective: Long non-coding RNAs (lncRNAs) are characterized as non-coding transcripts greater than 200 nucleotides. lncRNAs have extensive molecular connections with proteins and microRNAs, which are important in the regulation of gene expression in physiologic and pathologic states including cancer. About 18% of human LncRNAs were recently found to be associated with tumours. Many studies indicated that aberrant expression of LncRNAs play key roles in the progression and metastasis of NSCLC. In this study we evaluated the expression of long non-coding RNAs: GHET1, BACE1-AS, PANDA, UCA1 in non-small cell lung cancer. Material &amp; Methods: In this study, RNA was extracted from tumor tissues of NSCLC and paired adjacent normal lung tissues. After cDNA synthesis, the relative expression level of lncRNA GHET1, BACE1-AS, PANDA, and UCA1 genes was studied by TaqMan Real-Time PCR, and the data were analyzed by 2-∆∆CT. The t-test was used to compare the values and P-value &lt; 0.05 was considered statistically significant. Results: The data of qRT-PCR analysis revealed that the expression level of GHET1 gene in patients with NSCLC is increased (P= 0.0032) and BACE1-AS showed down-regulation (P= 0.0093). There was no significant change in the expression of PANDA and UCA1 genes. Conclusion: Our study sheds lights on the expression signature of several crucial lncRNAs in human lung cancer. This data not only could be further be utilized for different therapeutic approaches but also reveal the changes in biological processes of human lung tumors. &nbsp

Acute toxicity of Euphorbia turcomanica on Aphanius dispar

Piscicidal and molluscicidal activities of aqueous extracts of many members of the family Euphorbiaceae are well-known, but the toxicity potential of Euphorbia turcomanica was not yet studied on any aquatic animals. An acute toxicity test was performed by using a four-day static renewal test to determine the LC50 value of dried powder of E. turcomanica for the euryhaline fish, Aphanius dispar. The LC50 values at various exposure periods are 0.177±0.039 g/L for 24 hrs, 0.131±0.030 g/L for 48 hrs, 0.073±0.018 g/L for 72 hrs, and 0.052±0.013 g/L for 96 hrs. The toxicity of dried powder of E. turcomanica exhibits a positive correlation between fish mortality and exposure periods. As this is the first report about toxicity of E. turcomanica on A. dispar, the results could be only compared to that of other Euphorbiaceae as well as other fishes. It is concluded that the toxicity potential of E. turcomanica is comparable and close to that of well-documented Euphorbiaceae. It has been suggested that E. turcomanica products cannot be used directly in fish-inhabiting water reservoirs

An assessment of health research impact in Iran

Background: In recent years, Iran has made significant developments in the field of health sciences. However, the question is whether this considerable increase has affected public health. The research budget has always been negligible and unsustainable in developing countries. Hence, using the Payback Framework, we conducted this study to evaluate the impact of health research in Iran. Methods: By using a cross-sectional method and two-stage stratified cluster sampling, the projects were randomly selected from six medical universities. A questionnaire was designed according to the Payback Framework and completed by the principle investigators of the randomly selected projects. Results: The response rate was 70.4%. Ten point twenty-four percent (10.24%) of the studies had been ordered by a knowledge user organization. The average number of articles published in journals per project was 0.96, and half of the studies had no articles published in Scopus. The results of 12% of the studies had been used in systematic review articles and the same proportion had been utilized in clinical or public health guidelines. The results of 5.3% of the studies had been implemented in the Health Ministry’s policymaking. 62% of the studies were expected to affect health directly, 38% of them had been implemented, and among the latter 60% had achieved the expected results. Concerning the economic impacts, the most common expected impact was the reduction of ‘days of work missed because of illness or disability’ and impact on personal and health system costs. About 36% of these studies had been implemented, and 61% had achieved the expected impact. Conclusion: In most aspects, the status of research impact needs improvement. A comparison of Iran’s ranking of knowledge creation and knowledge impact in the Global Innovation Index confirms these findings. The most important problems identified were, not conducting research based on national needs, and the lack of implementation of research results.
