ABSTRACT
INTRODUCTION: It is essential to evaluate the impact of scientific publications through citation analysis in citation indexes. In addition, scientometric measures of social media also should be assessed. These measures include how many times the publications were read, viewed, and downloaded. The present study aimed to assess the scientific output of scholars at Kashan University of Medical Sciences by the end of March 2014 based on scientometric measures of Scopus, ResearchGate, and Mendeley. METHODS: A survey method was used to study the articles published in Scopus journals by scholars at Kashan University of Medical Sciences by the end of March 2014. The required data were collected from Scopus, ResearchGate, and Mendeley. The data were analyzed with descriptive statistics. Also, the Spearman correlation was used between the number of views of articles in ResearchGate with citation number of the articles in Scopus and reading frequency of the articles in Mendeley with citation number in Scopus were examined using the Spearman correlation in SPSS 16. RESULTS: Five-hundred and thirty-three articles were indexed in the Scopus Citation Database by the end of March 2014. Collectively, those articles were cited 1,315 times. The articles were covered by ResearchGate (74%) more than Mendeley (44%). In addition, 98% of the articles indexed in ResearchGate and 92% of the articles indexed in Mendeley were viewed at least once. The results showed that there was a positive correlation between the number of views of the articles in ResearchGate and Mendeley and the number of citations of the articles in Scopus. CONCLUSION: Coverage and the number of visitors were higher in ResearchGate than in Mendeley. The increase in the number of views of articles in ResearchGate and Mendeley also increased the number of citations of the papers. Social networks, such as ResearchGate and Mendeley, also can be used as tools for the evaluation of academics and scholars based on the scientific research they have conducted.
ABSTRACT
BACKGROUND: To assess the mortality predictive value of routine blood tests in patients with hip fracture. METHODS: In a retrospective descriptive study, medical records of 204 hip fractured patients with the age of 60 or older who were admitted to the Department of Orthopedics was considered regarding routine laboratory tests. Predictive values of these tests were assessed using receiver operating characteristic curve (ROC). RESULTS: The incidence of death due to hip fracture was 24%. The mortality rate was significantly increased with age > 65 (OR= 15). There was no significant difference between mortality in regards to gender. High plasma BUN (more than 20 mg/dl) and creatinine (more than 1.3 mg/dl) significantly increased the chance of mortality. [OR= 3.0 and OR=2.5 for BUN and creatinine, respectively]. Patients' mortality did not show any correlation with sodium and potassium plasma levels and blood hemoglobin. CONCLUSIONS: There is direct correlation between plasma levels of BUN and creatinine and 3-month mortality after hip fractures. Patients with high plasma levels of BUN were three times more likely to die than those with normal BUN. Also, patients with high plasma creatinine levels were 2.5 times more likely to die than those who had normal values. Mortality was also associated with increasing age but did not vary with gender. Patients aging more than 65 were 15 times more likely to die following a hip fracture than those with younger age.
