Citation analysis of five journals in andrology

AIM: To find out features in literature demand by researchers in the field of andrology and to offer advice on literature utilization and journal management. METHODS: Five andrology journals indexed by Science Citation Index Expanded (SCI-E) (Andrologia, Archives of Andrology, Asian Journal of Andrology, International Journal of Andrology, and Journal of Andrology) were included in the study. Original articles, editorials, reviews, corrections and letters from these journals were analyzed with bibliometric method for document loading, citations, information absorbing ability, and geographical coverage. RESULTS: The average number of references in each paper was 28.78. The main type of references was periodicals (94.32%), while books and other sources accounted for only 5.68%. Average Price index was 30.14%. The number of references in the first ranking 10 periodicals cited by the five journals made up 34.53% of the total references cited. Geographically, the five journals covered 6 continents with 42 countries or regions. CONCLUSION: Andrology journals have a wide coverage of literatures, which are related to reproductive medicine, urology, endocrinology and biochemistry. References in andrology journals are mainly periodicals and are relatively old. US, China and Japan lead the world in andrology researches for the number of papers published.     

‘Schicksal’ wissenschaftlicher Beiträge auf grossen Anästhesiekongressen

BACKGROUND: To evaluate the publication rate of abstracts presented during the German Anaesthesia Congress (DAK) in MEDLINE-listed journals in comparison to the publication rate of abstracts presented during the meeting of the European Society of Anaesthesiologists (ESA). METHODS: All abstracts of free papers (FP, orals) and posters of the 1994 DAK and the 1994 ESA meeting were included. Over a period of approximately 7 years (1993 to May 1999) the appearance of authors and abstracts topics in the literature were searched with the help of MEDLINE. Only original papers were included in the analysis. RESULTS: All 322 abstracts (268 FPs and 54 posters) of the DAK and all 244 abstracts (81 FP and 163 posters) of the ESA were analyzed. A total 122 of the DAK abstracts (37.9% of all abstracts) and 111 of the ESA abstracts (45.5% of all abstracts) were published in MEDLINE-listed journals. Posters presented at the DAK were as published often (37%) as were oral presentations (38%). Of the 122 abstracts of the DAK that were published 71 (58.2%) were published in English (in 38 different journals) and 51 (41.8%) were published in German (in 8 different journals), whereas 102 (92%) of the ESA abstracts were published in english (in 42 different journals). CONCLUSION: The overall portion of abstracts of the DAK published in MEDLINE indexed journals within 7 years was disappointing. The reasons for this may include deliberate avoidance of a publication (e.g. due to lack of interest to publish, no time) or low quality of the abstract that hinders publication in a MEDLINE indexed journal.

Andrology—development and future* Critical remarks after 45 years of medical practice

Summary. The development of andrology from its beginning to the present time is discussed from a historical point of view. Since andrology is a clinical discipline, only well-trained physicians are allowed to investigate and treat patients. The term ‘andrology’, which was first introduced in the USA more than 100 years ago, was independently reborn in Germany and thereafter used in other European countries. Since then, an increasing number of physicians all over the world have applied the term ‘andrology’ for their professional work. Many local societies and groups of andrologists were established. In 1969, Andrologia was founded as the first international journal of andrology in Germany. In the meantime, further andrological journals have been established. Concerning the future development of andrology, the following should be considered: (i) the organizational structure of andrology must include the basic training of physicians working in this field; (ii) the necessity of andrology as a medical specialty with regard to modern technologies of assisted reproduction etc., must be emphasized; (iii) internationally accepted recommendations for the training of andrologists with special reference to both clinical andrology and laboratory techniques should be established; (iv) andrology should be established as a separate specialty.

Which countries publish in important anesthesia and critical care journals?

Using a MEDLINE-based analysis, we studied the national origin of articles published in important anesthesia, pain, critical care, and emergency medicine journals. All journals in English listed in the Science Citation Index (SCI) of Journal Citation Reports under the subheadings Anesthesiology (n = 17) and Emergency Medicine & Critical Care (n = 13) were analyzed with the help of MEDLINE. Issues from 1996 and 1997 were included and summarized. Letters, abstracts, editorials, meeting reports, and news were not included. MEDLINE printouts were studied, and we classified the country of origin of the first author. The following subsets were defined: Anesthesia, Regional Anesthesia and Pain, Clinical Monitoring and Computing, Intensive Care Medicine and Resuscitation, and Emergency Medicine and Trauma. A total of 10,643 publications in 30 journals were published during 1996 and 1997. Of the 30 journals, 17 originate in the United States (US) and 8 from United Kingdom (UK). In 14 of the 17 US journals, >50% of the publications came from the US. The US was the most active nation, with a total of 4,283 articles (40.2% of all contributions), followed by the UK with 1,418 articles (13.3%). When looking at the number of publications with regard to inhabitants or impact factor per million inhabitants, small highly industrialized nations (Finland 35.41 and Sweden 33.9 articles/million inhabitants) were significantly more active than large highly industrialized countries (US 16.2, Germany 6.1, Japan 4.5 articles/million inhabitants). It is presumed that indicators of productivity in medical research are the number of articles published and the cumulative impact factor. During 1996 and 1997, the US was the most active nation with regard to publications in important journals in the areas of anesthesia, pain, critical care, and emergency medicine. Small highly industrialized nations, however, had a higher activity rate than larger countries. IMPLICATIONS: In a MEDLINE-based analysis, we examined the number of publications in important anesthesia, pain, critical care, and emergency medicine journals (n = 30) for the years 1996 and 1997 and analyzed these with regard to national origin. The United States was by far the most active nation in this medical area (4283 articles [40.2%]), followed by the United Kingdom (13.3%). With regard to publications per million inhabitants, small highly industrialized nations contributed overproportionally to publications in this area.     

Development of Italian research in anesthesiology and intensive care

The development of the Italian research in Anaesthesia and Intensive Care medicine has been evaluated by comparing the total number of papers in this field and the number of the Italian papers in this field published in the years 1977, 1987, 1997. The results showed: a) an increase of the total number of papers published in the indexed journals dedicated to Anesthesia and Intensive Care with an increase higher than 50% per decade. In the same period the number of Italian papers increased from virtual representation (1 paper/year) to 19 papers per year in 1997. b) The papers dedicated to intensive care medicine showed a similar increase. In spite of this, the indexed scientific production of the Italian scientific community remains underexpressed.     

Quality and retrieval of obstetrical anaesthesia randomized controlled trials

Purpose

Randomized controlled trials (RCTs) are suitable for meta-analysis and systematic reviews provided they are of high quality and are easy to retrieve. We determined these attributes of RCTs in obstetrical anaesthesia in a sample of available journals that are indexed in MEDLINE.

Source

Randomized controlled trials published between January 1985 and December 1994 in seven anaesthetic and three obstetric journals were identified by a MEDLINE search, and by handsearch of the same journals. Each RCT was assigned a quality score by a blinded rater using a reliable and validated scale. The quality of each RCT was described and compared over time and by journal. The comparative yield of MEDLINE and handsearch was evaluated.

Principal findings

Three hundred and forty RCTs were retrieved by MEDLINE and handsearch. Two hundred and twenty seven (65%) were identified by the MEDLINE search and 333 by the handsearch (98%). The median quality score was 3/5. There was no difference in score over time.Anesthesiology had the highest median score.Anaesthesia had the lowest (P < 0.05).

Conclusions

Care must be taken when reviewing obstetrical anaesthesia research. Strategies in addition to a MEDLINE search must be used to identify RCTs since more than one third were missed using MEDLINE alone. Poor quality RCTs are more likely to be biased in favour of a new treatment. Therefore, to increase the validity of reviews sensitivity analyses based on quality should be done.     

Randomized controlled trials in pediatric urology: room for improvement

PURPOSE: The primary purpose of this study was to ascertain what proportion of the body of published literature in pediatric urology is represented by randomized controlled trials. The secondary purpose was to assess the quality of these trials. MATERIALS AND METHODS: Using a predefined strategy, we conducted systematic computerized searches of the MEDLINE (years 1966 to 2004) and EMBASE (1980 to 2004) databases to identify all English language randomized controlled trials related to pediatric urology. Full text versions of identified studies were reviewed in blinded fashion for key demographic, methodological and statistical characteristics. Trial quality was assessed with the previously validated Jadad tool. RESULTS: The 77 identified randomized controlled trials represented only 0.4% to 0.9% of the indexed pediatric urology literature. The origins of these trials were Europe (40%), North America (26%) and a variety of other geographic centers (34%). A primarily surgical focus was present in 43% of the studies. Trials with negative results represented only 19% of the total randomized controlled trials. Generally, the trials were of low to fair quality (median Jadad score 3), with substandard methodological reporting and planning. There was not a significant trend toward improved quality in recent years. Trials from North America and Europe had higher quality (p = 0.007), as did those reporting negative results (p = 0.0001). CONCLUSIONS: Randomized controlled trials in pediatric urology constitute only a small proportion of the body of published literature in the field. High quality studies are uncommon. Efforts should be made to increase the number of well designed, randomized controlled trials in pediatric urology.
