Investigating Web impact factors of type 1, type 2 and type 3 medical universities in Iran

Investigation of the web impact factor and analysis of the web links belong to webometric studies. A high impact factor, accompanied by more frequent links to a particular website, can indicate greater influence and better accessibility of that particular site. In this regard, bearing in mind the significance of medical universities' web sites for education and research, the current study compared and analyzed their impact factors, their web links and web pages, using AltaVista search engine. The investigation included different ranks of medical universities, commonly referred to as type 1, type 2 and type 3 universities in Iran. The median was used as a measure of central tendency of the scores. The search engines of AltaVista were adopted on 26 February 2010 to collect the data. According to the results, in terms of indexed pages, Shahid Baheshti of type 1, Guilan of type 2, and Shahrekord of type 3 universities had the best records. Regarding web links, medical universities of Iran, Kermanshah and Lorestan, from type 1, type 2 and type 3 universities had the best records and, in terms of impact factor, universities of Ahvaz (type 1), Zahedan (type 2), and Fessa (type 3) manifested the greatest influence. As the results imply, the universities are expected to pay more attention to webometric issues; they are also recommended to allocate more budget to enhance their web pages

The Features of Cardiovascular Papers and Impact on Citations

Introduction: The number of citations is a factor in evaluating the quality of scientific articles. The present study aims to examine the factors affecting the citation rate of cardiovascular articles. Methods: In this scientometrics study, the research population is all cardiovascular articles in 2014 in Web of Science (WoS), including a sample of 381 articles studied. Pearson correlation coefficient, Mann–Whitney, Kruskal–Wallis, and Bonferroni tests were used to examine the impact of article features on citations. Results: The results indicated that all quantitative variables (title length, number of authors, author's H-index, journal IF, number of pages, number of author's keywords, number of keywords-plus, number of references)had a significant relationship with the number of citations (P-value<0.001), except for the number of article keywords.  All of the qualitative variables (title length, number of authors, author's H-index, journal IF, number of pages, number of author's keywords, number of keywords-plus, number of references) also affect the number of citations (P-value<0.001). Open access articles, articles with the first author from Australia and North America, articles with international collaboration, and meta-analysis articles have received a more citation rate. Conclusion: Paying attention to the factors affecting the citation rate of cardiovascular articles can be of help to cardiovascular centers for policy-making and researchers in determining the research approach. In this way, they can improve the citation of their works

Analysis and Identification of Barriers to Using Evidence-based Databases in Nurses

Introduction: Evidence-based nursing uses the best scientific evidence in clinical decision-making for the best care. The essential step in this process is to find evidence from databases.  However, there are many barriers to its implementation that need to be identified. The purpose of this study was to determine the barriers to using evidence-based databases and their relationship to contextual characteristics. methods: This is a descriptive cross-sectional study in which 214 nurses working in educational hospitals of Shahid Beheshti University of Medical Sciences participated in 2020. Data were collected using a researcher-made questionnaire. Data were analysed by SPPS software version 23. Descriptive statistics, independent t-test, and ANOVA were used for data analysis. Results: Nurses' knowledge of evidence-based databases is average and low. The biggest is the weakness in formal and informal evidence-based nursing education. The results also showed that nurses with higher education (P-value = 0.002) and educational supervisors      (P-value = 0.015) and supervisors (P-value = 0.017) reported more barriers. Conclusion:  It is recommended that the head of departments and policymakers in nursing education make general revisions to the content of the nursing curriculum for the evidence-based practice concepts point of view and provide necessary facilities for relevant training courses by workshops, congresses, etc

Effect of dietary approaches to stop hypertension, and standard diets with and without curcumin on interleukin-1 alpha, 5-alpha reductase gene expressions, and androgenic and glycemic profile in polycystic ovary syndrome women undergoing IVF

Full Title: Effect of dietary approaches to stop hypertension, and standard diets with and without curcumin on interleukin-1 alpha, 5-alpha reductase gene expressions, and androgenic and glycemic profile in polycystic ovary syndrome women undergoing in vitro fertilization treatment: A study protocol Background: Polycystic ovary syndrome (PCOS) is one of the most common endocrine diseases with major reproductive and metabolic complications with an impact on public health. Hyperandrogenism and chronic inflammation have been suggested as the leading cause of pathophysiology and clinical manifestations associated with PCOS. It seems that the altered expression of genes involved in the synthesis of proinflammatory cytokine and androgens contribute to the promotion of PCOS. Objective: This trial aims to determine the effects of dietary approaches to stop hypertension (DASH) and standard diets with and without curcumin supplementation on the gene expression of interleukin (IL)-1α alpha, IL-5α reductase and androgenic and glycemic profile among PCOS patients, who are candidates for in vitro fertilization. Materials and Methods: 96 infertile women with PCOS, aged 18-40 yr, will participate in this randomized, placebo-controlled clinical trial. Based on treatment conditions and body mass index, the participants will be randomly divided into 4 equal groups using a randomized block design. They will receive a DASH or standard diet containing 52% carbohydrate, 18% protein, and 30% total fat, with the same prescribed sodium, plus 500 mg twice daily curcumin or placebo for 12 wk. The mRNA expression of IL-1α, 5α reductase, and androgenic and glycemic profiles will be measured at baseline and at the end of the study. Conclusion: Concomitant administration of DASH diet and curcumin supplementation may reduce IL-1α, 5α reductase gene expressions, and improve glycemic and androgenic profiles. Key words: Polycystic ovary syndrome, Dietary approaches to stop hypertension, Curcumin, Fertilization in vitro, Gene expression

Health information seeking behaviour in academic population and its relationship with carcinophobia

Health information-seeking behavior is how to search, find and use disease-related information, information about health-threatening factors and activities related to health promotion. One of the issues affecting people's quality of life is chronic diseases, of which cancer can be mentioned. Cancer incidence is rising over the last years . It cannot be stated for sure that the Fear and concern about cancer which is named carcinophobia,  always cause a lack of follow-up and avoidance of people seeking cancer information; however, considering different time intervals and in different cultures, the same Fear and concern as the stimulus, stimulates or forces the people to track and seek cancer information.The purpose of this analytical survey was clarifying the situation of Health information-seeking behaviour among university students both undergraduate and postgraduate as academic population during cancer outbreak. Also our aim is to  determine the relationship between carcinophobia and information-seeking behavior in this population. Research findings while clarifying the situation of Health information seeking behavior in the academic population, can indicate that carcionphobia causes more information search or is a barrier to information search. The samples of this analytical survey include 243  college students who were selected by cluster-class methodology. The research tool was derived from the Cancer Information Questionnaire Levin (L_CIS). Pearson correlation test was used for the relationship between variables. The results showed that the average total score of students' fears of the disease was 27.20, which was high and the main motive for the search for cancer health information was the protection of personal hygiene(56.4%). " Knowing how to treat cancer (54.7%) and the awareness of new trends in medicine (44.5%) were in the second and third rankings of the purpose and motivation of the search for information. Three components including "Lack of effective communication with Treatment staff  (such as physicians or nurses), "Lack of mastery in searching or finding of health information resources" and "Lack of mastery in the use of print or online health information resources" in average were the most important problems and barriers to obtaining the required information resulting from Fear of cancer. With increasing Fear of cancer, people's willingness to search for information through friends and watching TV shows increased, but the severe, and morbid Fear of cancer reduced the desire of individuals to seek health information

How to test normality distribution for a variable: a real example and a simulation study

Many commonly used statistical methods require that the population distribution be nearly normal. Unfortunately, in some papers the one-sample Kolmogorov-Smirnov test has been used for testing normality while the assumptions of applying this test are not satisfied. To conduct this test, it is assumed that the population distribution is fully specified. In practical situation where the mean and SD of population distribution is not specified in advance, one can use a modification of the K-S test for checking the normality assumption which is called, Lilliefors test. In this paper, we explain the method of computing this test with some common statistical softwares such as SPSS, S-PLUS, R and StatXact and utilize a dermatology dataset from Skin Research Center of Shohada-e-Tajrish hospital to illustrate how the use of the one-sample K-S (with the mean and SD estimated from the sample) instead of its modification can be misleading in practice. We also use Monte Carlo simulation to compare the approximate power of the one-sample K-S test (with the estimated population mean and SD) with Lilliefors test in some common specified continuous distributions. The result indicates that one should not use the one-sample K-S test for assessing the normality assumption in practical situation.

Success rate and ART outcome of microsurgical sperm extraction in non obstructive azoospermia: A retrospective study

Background: The management of non-obstructive azoospermia (NOA) disease relies on microdissection testicular sperm extraction (micro-TESE). Few studies have assessed the role of micro-TESE in men with NOA in our country. Objective: The aim of the current study was to investigate the success rate of micro- TESE. Materials and Methods: This retrospective descriptive-analytical study was conducted on 463 men with NOA in Yazd Reproductive Sciences Institute during September 2017 through September 2019. Sperm were retrieved and frozen according to the rapid sperm freezing protocol. After preparing the oocyte of the male partner’s spouse, sperms were thawed and then entered the intracytoplasmic sperm injection process. The clinical pregnancy of individuals was confirmed via ultrasound. Demographic data were extracted from medical records. Results: The success rate of micro-TESE was 38% and successful fertilization, biochemical pregnancy, clinical pregnancy, and live birth were observed in 111 (85.4%), 29 (22.3%), 29 (22.3%) and 14 (10.7%) men, respectively. A significant difference was seen between the two groups, regarding age (p = 0.01). In addition, the mean follicle-stimulating hormone in men with positive micro-TESE was significantly lower than in men with negative micro-TESE (p = 0.02). Conclusion: The success of pregnancy in couples with NOA managed via micro-TESE was significant. The study found that the success rate of micro-TESE was higher in older men and in those with lower follicle-stimulating hormone levels.
