Assessment of the quality of randomized controlled trials published in Indian Medical Journals from 2020 to 2021: A cross-sectional study

Background: A randomized controlled trial (RCT) is the most valued method for evaluating the drug safety and its efficacy. However, due to incomplete reporting, RCTs may not be a reliable source of information and can lead to false interpretation of outcome. Aim and Objective: The aim of this study was to analyze the completeness in reporting of RCTs published in the Indian medical journals (IMJs) according to the Consolidated Standards of Reporting Trials (CONSORT) 2010 checklist items and to analyze, if there was a variation in the completeness between registered and unregistered trials. Materials and Methods: This was a cross-sectional study conducted in the Department of Pharmacology, Bangalore Medical College and Research Institute. The clinical trials published by the IMJs between January 2020 and August 2021 were accessed online, and its full text versions published were downloaded. Completeness in reporting of the RCTs with respect to different CONSORT checklist domains was recorded. The impact of trial registration and CONSORT endorsement on the completeness of reporting RCTs according to CONSORT checklist was determined. Descriptive statistics was used to assess and summarize the data. Results: The overall completeness of reporting was 82.4%, better than the previous years. Major areas of reporting deficiencies were in the title and abstract, result, and registration domains. Registered trials reported better than unregistered. Conclusions: Endorsement of CONSORT in the journal had no difference in reporting. Although the quality of reporting RCTs in the IMJs has improved, it remains unsatisfactory. Completeness of trial reporting could be improvised by strict implementation of CONSORT guidelines.

Medicina y cultura visual: la fotografía en revistas científicas y la producción de conocimiento médico experimental en Argentina, 1890-1915 / Medicine and visual culture: photography in scientific journals and the production of experimental medical knowledge in Argentina, 1890-1915

Resumen En el presente artículo se abordan las maneras en que la fotografía fue parte de las estrategias argumentativas y expositivas de los profesionales de la medicina y su rol en la producción de conocimiento experimental entre 1890 y 1915. Para dar cuenta de estas cuestiones se relevaron revistas médicas representativas del período siempre teniendo en cuenta los avances en las técnicas de reproducción de imágenes. El análisis realizado permite dar cuenta de cómo las fotografías fueron parte de las explicaciones presentadas ante la comunidad científica para persuadir de la eficacia de tratamientos experimentales y procedimientos quirúrgicos novedosos, en un contexto de profesionalización de la medicina y necesidad de legitimación de una "cultura de laboratorio".

Abstract This article addresses how photography was part of the argumentative and expository strategies of medical professionals and its role in the production of experimental knowledge between 1890 and 1915. To investigate these issues, representative medical journals of the period were surveyed, always considering the advances in image reproduction techniques. The analysis carried out allows us to observe how the photographs were part of the explanations presented to the scientific community to persuade the efficacy of experimental treatments and novel surgical procedures, in the context of the professionalization of medicine and the need to legitimize a "culture of the laboratory."

Travestismo y transexualidad en las revistas argentinas de medicina, 1971-1982 / Transvestism and transsexuality in Argentine medical journals, 1971-1982

Resumen El presente artículo aborda los discursos producidos por el campo médico argentino en torno a las iniciativas de corporización de travestis y transexuales en Argentina entre 1971 y 1982. A través del relevamiento y análisis de una selección de artículos publicados en revistas académicas de medicina, se analizan los sentidos que profesionales de la salud asignaron a las mismas antes de la producción de fallos judiciales y normativas nacionales que reconocen la identidad de género como un derecho humano. El análisis realizado permite identificar las particularidades que asumían dichas iniciativas de corporización en el período de estudio, así como las formas en las que el campo médico argentino les imprimió sentidos morales, técnicos y profesionales.

Abstract This article deals with the discourses produced by the Argentine medical field relating to body transformation initiatives on the part of transvestites and transsexuals in Argentina from 1971-1982. Based on the compilation and analysis of a set of articles published in academic medical journals, it examines the meanings that health professionals assigned to these initiatives prior to the legal rulings and national legislation that recognized gender identity as a human right. This analysis helps identify the particular features of those body transformation initiatives during the period studied, as well as the ways in which the medical field in Argentina attached moral, technical and professional meanings to them.

Análisis bibliométrico de la retinopatía diabética en revistas médicas cubanas: un producto de información con valor agregado / Bibliometric analysis of diabetic retinopathy in Cuban medical journals: an information product with added value

Los estudios métricos sobre la producción científica constituyen productos de información útiles a las comunidades académicas; sin embargo, no existen abundantes indagaciones que cuantifiquen y evalúen las fuentes que publican trabajos sobre retinopatía diabética. Este trabajo se propuso determinar la producción científica sobre retinopatía diabética publicada en revistas médicas cubanas entre los años 1970 y 2017. Se realizó una revisión bibliográfica a partir de la identificación en los registros de los términos [adultos - retinopatía diabética]. Se utilizó el gestor de referencias bibliográficas Zotero, para recuperar y analizar los metadatos de cada artículo seleccionado; Microsoft Excel para la tabulación de los resultados y Mindjet mindManager (2010), para la elaboración del mapa conceptual. Se seleccionaron 56 artículos relacionados con la temática después de aplicados los criterios de inclusión y exclusión. La producción científica de la retinopatía diabética publicada en revistas médicas cubanas se concentra en los últimos 10 años. El peso de la distribución de los artículos recae en revistas que pertenencen a Institutos Nacionales. Asimismo, la tendencia de los tipos de trabajos se concentra en investigaciones originales de carácter descriptivo, estudios de caso y artículos de revisión; y en menor cuantía los estudios de cohortes, analíticos y experimentales(AU)

Metric studies about scientific production are information products useful to academic communities. However, not many inquiries are available which quantify and evaluate the sources publishing papers about diabetic retinopathy. The present study was aimed to determine the scientific production about diabetic retinopathy published in Cuban medical journals in the period 1970-2017. A bibliographic review was conducted based on identification of records of the terms [adults - diabetic retinopathy]. Retrieval and analysis of the metadata for each paper selected was performed with the bibliographic reference manager Zotero, while Microsoft Excel was used for tabulation of results and Mindjet MindManager (2010) to develop the conceptual map. A total 56 papers about the study topic were selected upon application of inclusion and exclusion criteria. Scientific production about diabetic retinopathy published in Cuban medical journals is concentrated in the last ten years. Most of the papers were found to have been published by journals sponsored by national institutes. Regarding paper types, most were original studies of a descriptive nature, case studies and review papers, and to a lesser degree cohort, analytic and experimental studies(AU)

Statistical reporting requirements for medical journals: Amplifications and explanations / 中华流行病学杂志

Our study aimed to amplify and explain the items of statistical reporting requirements proposed by medical journals,and to improve the statistical repotting quality of medical articles.Statistical reporting requirements were obtained from the reporting standards published by the International Committee of Medical Journal Editors (ICMJE),the Enhancing the QUAlity and Transparency of Health Research (EQUATOR) network,and the editorial board of Chinese Medical Journal,etc.The items involved in statistical reporting requirements were summarized as issues of study design,statistical analysis,and interpretation of results.Each item was amplified based on cases of original articles.It is noticeable that the statistical reporting requirements of English medical journals generally referring to guidance documents,including "Recommendations for the conduct,reporting,editing,and publication of scholarly work in medical journals" proposed by the ICMJE,or the statements for different study types published by the EQUATOR network,where the statistical reporting of medical articles had been detailed specified.The statistical reporting requirements of Chinese medical journals,however,were usually stated by the editorial boards.Although the formats and contents of statistical analysis had been regulated,the requirements of Chinese medical journals were to some extent insufficient and should be enhanced in accordance with the intemational standards.In conclusion,the amplification and explanation of statistical reporting requirements were expected to help investigators understand the requirements for statistical reporting in medical researches,so as to effectively improve the quality of medical articles.

An analysis of adherence to the World Health Organisation guidelines pertaining to drug promotional literature by pharmaceutical firms

Background: Pharmaceutical companies used Drug Promotion Literatures (DPLs) as a major tool to advertise their new products. World Health Organization (WHO) has set some guidelines for promotion of drug literature. Thus, this study aimed to evaluate various DPLs for their accuracy and credibility as per WHO ethical criteria.Methods: This was an observational and cross-sectional study. Total 100 drugs advertisements published in various medical journals were collected from the library of the college. Advertisements were selected based on inclusion and exclusion criteria. The selected advertisements were evaluated based on the WHO ethical criteria for drug promotion.Results: From 100 advertisements, 73 were single drug whereas 27 were fixed drug combinations. Antimicrobials (16%) were the most promoted advertisements. Only 28% of the advertisements carried references to support their claim. Out of which majority (91.78%) were from journal articles. The generic name, brand name, names of active ingredients, manufacturer, distributor and dosage regimen were mentioned in majority of advertisements. Drug interactions (12%), contraindications (22%), precautions (24%) and side effects (22%) were least mentioned in the advertisements.Conclusions: It was observed that none of the advertisement followed all the guidelines laid down by WHO. Pharmaceutical companies should follow ethical regulatory measures to promote their product in various journals. The regulatory authority must ensure the pharmaceutical companies to follow ethical guidelines for publishing various drug promotional literatures.

Bibliographical Characteristics of North Korean Medical Journals and Articles

The aim of our work was to analyze the bibliographical characteristics of 9 North Korean medical journals and articles. All journals show only ten pieces of information, such as publication dates and table of contents, and do not provide submission guidelines and journal policy. Most of the journals were published four times a year. Editorials often share government policy. Research articles are very short and compressed. The journals often publish articles on oriental medicine and medical information useful to the public. In conclusion, the journals were published in their own unique style and format, which are far from the global standard.

Introducing: Slices

@#Medical journals are meant to both reflect the science behind medical practice and facilitate the advancement of the discipline.1 They present newly generated knowledge in the field, with the general aim of improving health care. The effectiveness of a journal article to convey its messages can potentially affect the development of health care. Medical information from journals used to be designed for medical practitioners alone. Now, increasingly, publishers feel the need to package the same information to make it accessible to different types of readers. Almost always, readers go to journals to look for evidence that can support decisions about health. The common questions readers ask when looking for evidence in medical literature have something to do with incidence or prevalence of conditions, effectiveness of therapy or prevention, accuracy of diagnostic approaches, and associations of exposures and outcomes.

To be, or not to be: The calculated politics of acupuncture in JAMA / 中国结合医学杂志

Ten acupuncture-related articles were published in The Journal of the American Medical Association (JAMA) between 1998 and 2017. Five studies showed positive results in terms of the effectiveness of acupuncture/Chinese medicine (CM); five studies showed negative results. This article summarizes the acupuncturerelated clinical trials published over the last 20 years in JAMA, and addresses what seems to be a fundamental ambivalence in Western medical journals regarding the scientific validity of acupuncture/CM. As yet there has been no consensus on the role of acupuncture in healthcare in Western countries. This is hardly surprising, considering the conflicting evidence found in published studies. Skepticism regarding acupuncture/CM is largely grounded in the fact that an accurate model for assessing the true clinical effects of acupuncture has yet to be created. This article discusses some of the pitfalls which result from applying Western-based scientific principles to CM, and suggests that in many cases, "negative" studies have been misinterpreted. The clinical experience of acupuncture practitioners is often in direct conflict with many of the negative conclusions published in journals. We are in need of an accurate model for sham and placebo treatments, and must analyze all published studies for design flaws and faulty conclusions.

A propósito de la presentación y discusión de casos clínicos / Presentation and discussion of clinical cases

La presentación de casos (case-report) ha sido una tradición en medicina clínica de larga data, así como una de las vías más motivantes de compartir experiencias con otros colegas y para transmitir conocimientos y habilidades a los educandos. A ello se unen los beneficios inmediatos que representan para la atención médica con calidad de los enfermos, que contribuyen a mejorar las relaciones humanas y profesionales y despiertan un sentimiento de satisfacción en los que participan, pues se intercambian informaciones, opiniones, experiencias y sugerencias siempre muy gratificantes. Sin embargo, en las últimas décadas, la moda de las actualizaciones, las revisiones sistemáticas, los temas relacionados con la medicina basada en la evidencia, las guías de práctica clínica, los protocolos y los resultados de diversos tipos de investigaciones en el campo de la clínica llevadas a cabo con diseños complejos y la aplicación de métodos estadísticos complicados -todos asuntos de interés y que se deben tener en cuenta-, han venido a ocupar buena parte del espacio que antes se dedicaba a las presentaciones de casos en diversas revistas médicas. El objetivo del presente trabajo es insistir en lo importante que sería actualizar y perfeccionar la presentación y discusión de casos, a partir de todas las posibles fuentes y espacios disponibles con que contamos, por los beneficios que conllevan, así como su comunicación oral en eventos y su presencia en las publicaciones médicas, con el propósito de incrementar cada vez más su rol en potenciar el caudal de conocimientos, habilidades y ética que tanto nos hacen falta en esta nueva época(AU)

A case-report has been a long standing tradition in clinical medicine and one of the most motivating ways to share experiences with other colleagues and to transmit knowledge and skills to learners. Added to this, the immediate benefits they represent for health care quality of patients contribute to improving human and professional relationships and awaken a sense of satisfaction in those participating, due to information, opinions, experiences, and suggestions which are exchanged forever very rewarding. However, in recent decades, fashion updates, systematic reviews, issues related to evidence-based medicine, clinical practice guidelines, protocols and results of various types of research in the field of clinical carried out with complex designs and application of complicated statistical methods - all issues of concern and must be taken into account - have come to occupy much of the space formerly devoted to of cases reports in various medical journals. The aim of this paper is to emphasize how important it would be to update and improve the reports and discussions of cases from all possible sources and available spaces we have, for the benefits they bring, and their oral communication in events its presence in the medical literature, in order to increase their role in enhancing the flow of knowledge, skills, and ethics that we lack so much in this new times(AU)
