Global mapping of randomised trials related articles published in high-impact-factor medical journals: a cross-sectional analysis
2020
[Background]: Randomised controlled trials (RCTs) provide the most reliable information to inform clinical practice and patient care. We aimed to map global clinical research publication activity through RCT-related articles in high-impact-factor medical journals over the past five decades.
Evaluation of the methodological quality of articles on autologous breast reconstruction
2018
Abstract Background Breast cancer remains the most common cancer among women worldwide. Autologous breast reconstruction may contribute toward restoring body image and improving quality of life after mastectomy. This systematic literature review describes differences in the quality and type of studies investigating autologous breast reconstruction techniques over time. Methods MEDLINE was searched for articles related to the surgical techniques, namely, TRAM, LADO, DIEP, and SGAP/IGAP, for the periods 1970 to 2007 and 2008 to 2010. The quality and type of studies were compared across the two time periods. Full-texts were evaluated according to prespecified quality criteria. Results The MEDL…
Evaluation of the quality of publications on randomized clinical trials using the Consolidated Standards of Reporting Trials (CONSORT) statement guid…
2011
The main reason for conducting a clinical trial (CT) is to test the effect of a drug or medical procedure to improve treatment of a disease. CTs contribute most when they are rigorously conducted and the results are published adequately. The aim of this study is to assess, using the CONSORT statement guidelines, the quality of reporting of completed CTs conducted at a tertiary hospital to determine which sections of the articles should be improved. CTs published between 2002 and 2008 were identified by searching the MEDLINE and Cochrane Library. Forty of 127 completed CTs were published. There was a marked increase in the number of articles and the quality of the journals that published the…
Musculoskeletal examination in young athletes and non-athletes:the Finnish Health Promoting Sports Club (FHPSC) study
2018
ObjectivesTo determine the inter-rater repeatability of a musculoskeletal examination and to compare findings between adolescent athletes and non-athletes in Finland.MethodsIn this cross-sectional study, a musculoskeletal examination assessing posture, mobility and movement control was carried out by a sports and exercise medicine physician on 399 athletes aged 14–17 years and 177 non-athletes. Within 2 weeks another sports and exercise medicine physician repeated the examination for 41 adolescents to test the inter-rater repeatability.ResultsIn total, 10 of the 11 tests performed had at least moderate inter-rater reliability (κ ≥0.4 or percentage agreement >80%). Athletes more often tha…
Bibliometric analysis of leishmaniasis research in Medline (1945-2010)
2012
Background Publications are often used as a measure of success of research work. Leishmaniasis is considered endemic in 98 countries, most of which are developing. This article describes a bibliometric review of the literature on leishmaniasis research indexed in PubMed during a 66-year period. Methods Medline was used via the PubMed online service of the US National Library of Medicine. The search strategy was Leishmania [MeSH] or leishmaniasis [MeSH] from 1 January 1945 until 31 December 2010. Neither language nor document type restrictions were employed. Results A total of 20,780 references were retrieved. The number of publications increased steadily over time, with 3,380 publications f…
Small airways in in sedentary and endurance-trained dystrophic (mdx) mice
2015
The effects of mild endurance exercise training on the small airways in mdx mice are unknown. We compared epithelial thickness and turnover, apoptosis, and stress marker expression in small airways of mdx mice and wild-type (WT) controls, at rest and during exercise training. Mdx and WT mice were randomly assigned to sedentary (mdx-S, n=17; WT-S, n=19) or trained (mdx-EX, n=14; WT-EX, n=16) groups. Low-intensity endurance training (running on a wheel) was done 5 d/wk for 6 wk at progressively increasing speed (rpm from 16 to 24) and time (15 min to 1 h). Lungs were processed for light microscopy and periodic acid Schiff (PAS) staining. Hsp60 and PCNA were quantified by immunohistochemistry.…

Melting point, molecular symmetry and aggregation of tetrachlorobenzene isomers: the role of halogen bonding
2018
Tetrachlorobenzenes represent one of the best known, but not yet fully understood, group of isomers of the structure–melting point relationship. The differences in melting temperatures of these structurally related compounds were rationalized in terms of the hierarchy and nature of formed noncovalent interactions, and the molecular aggregation that is influenced by molecular symmetry. The highest melting point is associated with the highly symmetric 1,2,4,5-tetrachlorobenzene isomer. The structures of less symmetrical 1,2,3,4-tetrachlorobenzene and 1,2,3,5-tetrachlorobenzene, determined at 270 and 90 K, show a distinct pattern of halogen bonds, characterized by the different numbers and typ…
Scholarly publishing depends on peer reviewers
2018
The peer-review crisis is posing a risk to the scholarly peer-reviewed journal system. Journals have to ask many potential peer reviewers to obtain a minimum acceptable number of peers accepting reviewing a manuscript. Several solutions have been suggested to overcome this shortage. From reimbursing for the job, to eliminating pre-publication reviews, one cannot predict which is more dangerous for the future of scholarly publishing. And, why not acknowledging their contribution to the final version of the article published? PubMed created two categories of contributors: authors [AU] and collaborators [IR]. Why not a third category for the peer-reviewer? published
