Reporting of randomized controlled trials in Hodgkin lymphoma in biomedical journals

BACKGROUND: Randomized controlled trials (RCTs) are the best tool to evaluate the effectiveness of clinical interventions. The Consolidated Standards for Reporting Trials (CONSORT) statement was introduced in 1996 to improve reporting of RCTs. We aimed to determine the extent of ambiguity and reporting quality as assessed by adherence to the CONSORT statement in published reports of RCTs involving patients with Hodgkin lymphoma from 1966 through 2002. METHODS: We analyzed 242 published full-text reports of RCTs in patients with Hodgkin lymphoma. Quality of reporting was assessed using a 14-item questionnaire based on the CONSORT checklist. Reporting was studied in two pre-CONSORT periods (1966-1988 and 1989-1995) and one post-CONSORT period (1996-2002). RESULTS: Only six of the 14 items were addressed in 75% or more of the studies in all three time periods. Most items that are necessary to assess the methodologic quality of a study were reported by fewer than 20% of the studies. Improvements over time were seen for some items, including the description of statistics methods used, reporting of primary research outcomes, performance of power calculations, method of randomization and concealment allocation, and having performed intention-to-treat analysis. CONCLUSIONS: Despite recent improvements, reporting levels of CONSORT items in RCTs involving patients with Hodgkin lymphoma remain unsatisfactory. Further concerted action by journal editors, learned societies, and medical schools is necessary to make authors even more aware of the need to improve the reporting RCTs in medical journals to allow assessment of validity of published clinical research.

Educational Technology-Benefits and Barriers

Statement of Problem: The second background paper for the Medical School Objective Project (MSOP), defined Educational Technology (ET) as the use of information technology to facilitate student’s learning.1 Medical schools as a group have made limited progress in accomplishing the recommended educational technology goals and there had been much greater use of such technology in basic sciences courses than in clinical clerkships. We will explore the positive and negative implications of incorporating ET into the educational experience of TMC schools. [See PDF for complete abstract]

Waking Up to Sleep Medicine Education

Background: Sleep disorders are an important cause of morbidity among our population with billions of dollars spent on direct and indirect costs attributed to sleep disorders. In spite of raising prevalence and morbidity, surveys have shown inadequate education in sleep medicine at all levels at medical school. According to national sleep disorders research plan data, in 1990 about 37 % of medical schools did not offer any sleep education and of the schools which offered it, the average time devoted to sleep medicine was about 2 hours. Sleep disorders have found to be uniformly under diagnosed in primary care settings. [See PDF for complete abstract]

Operationalizing Professionalism: A Course in Ethical Decision Making

All U.S. medical schools require some medical ethics education and must now ensure that their graduates, residents, and faculty exhibit competence in the area of professionalism and professional medical ethics. However, there remain many challenges to implementing formal ethics and professionalism education into medical school curricula. [See PDF for complete abstract]

European undergraduate curriculum in geriatric medicine developed using an international modified Delphi technique.

INTRODUCTION the rise in the number of older, frail adults necessitates that future doctors are adequately trained in the skills of geriatric medicine. Few countries have dedicated curricula in geriatric medicine at the undergraduate level. The aim of this project was to develop a consensus among geriatricians on a curriculum with the minimal requirements that a medical student should achieve by the end of medical school. METHODS a modified Delphi process was used. First, educational experts and geriatricians proposed a set of learning objectives based on a literature review. Second, three Delphi rounds involving a panel with 49 experts representing 29 countries affiliated to the European Union of Medical Specialists (UEMS) was used to gain consensus for a final curriculum. RESULTS the number of disagreements following Delphi Rounds 1 and 2 were 81 and 53, respectively. Complete agreement was reached following the third round. The final curriculum consisted of detailed objectives grouped under 10 overarching learning outcomes. DISCUSSION a consensus on the minimum requirements of geriatric learning objectives for medical students has been agreed by European geriatricians. Major efforts will be needed to implement these requirements, given the large variation in the quality of geriatric teaching in medical schools. This curriculum is a first step to help improve teaching of geriatrics in medical schools, and will also serve as a basis for advancing postgraduate training in geriatrics across Europe.

Women physicians' specialty choices

Three hypotheses have been offered to explain the historical specialty selection by women physicians. They are: (1) women choose the specialty for which the training requirements and working conditions interfere least with their commitments to marriage and children; (2) women tend to select the more "feminine" specialties such as pediatrics and psychiatry, and to avoid the "masculine" fields such as surgery; and (3) women have been deliberately excluded from male-dominated fields such as surgery. While the above hypotheses may be true to a greater or lesser degree, none of them has been adequately tested.^ The major study hypotheses are as follows: (1) female physicians' choice of specialty is influenced by the following reasons: (a) family responsibilities; (b) sex role expectations; and (c) sex discrimination; (2) female physicians' choice of specialty is also influenced by their age and ethnicity; and (3) the primary reasons for choosing a given specialty vary by type of specialty.^ The reasons for specialty selection will be explored based on a survey of women graduates of one of the oldest medical schools in the United States, The University of Texas Medical Branch (UTMB) in Galveston, Texas (n = 930). The survey response rate was 75.3% (700 respondents).^ The results for the first study hypothesis showed that fewer than 14% of the respondents agreed that sex role expectations, sex discrimination and family responsibilities played a role in their choice of specialty. Fifty nine percent of the respondents disagreed with the idea that sex role expectations influenced specialty selection and 64% disagreed that family responsibilities had an effect on the selection of their specialty. Around half (49%) were uncertain of the influence of sex discrimination. It was concluded that sex discrimination, sex role expectations and family responsibilities did not have a major impact on specialty selection.^ With respect to the second hypothesis, age was significant in Internal Medicine, Obstetrics/Gynecology and Psychiatry. Women physicians in Internal Medicine and Obstetrics/Gynecology were significantly younger (less than 45 years old) while physicians in Psychiatry were significantly older (45 years or older) than other specialties studied.^ The third hypothesis was confirmed: the reasons for choosing a given specialty varied by specialty.^ Respondents' comments written on the survey provided insight into other possible reasons for specialty selection including exploration of the role of mentoring and job satisfaction.^ The retrospective cross-sectional study design used in this study does not adequately capture the fact that different reasons may be given for the choice of specialty at different points in time, e.g., as the time of choosing a residency program versus several years into the future.^ In conclusion, approaches that explore the range of reasons that women elect to enter and stay within a given specialty must be explored to gain richer understanding of the complex and dynamic nature of women physicians' professional lives.

Evaluation of Knowledge Regarding Diagnostic Strategies for Genetic Diseases in Select Residents

Genetics education for physicians has been a popular publication topic in the United States and in Europe for over 20 years. Decreasing numbers of medical genetics professionals and an increasing volume of genetic information has created a dire need for increased genetics training in medical school and in clinical practice. This study aimed to assess how well pediatrics-focused primary care physicians apply their general genetics knowledge to clinical genetic testing using scenario-based questions. We chose to specifically focus on knowledge of the diagnostic applicability of Chromosomal Microarray (CMA) technology in pediatrics because of its recent recommendation by the International Standard Cytogenomic Array (ISCA) Consortium as a first-tier genetic test for individuals with developmental disabilities and/or congenital anomalies. Proficiency in ordering baseline genetic testing was evaluated for eighty-one respondents from four pediatrics-focused residencies (categorical pediatrics, pediatric neurology, internal medicine/pediatrics, and family practice) at two large residency programs in Houston, Texas. Similar to other studies, we found an overall deficit of genetic testing knowledge, especially among family practice residents. Interestingly, residents who elected to complete a genetics rotation in medical school scored significantly better than expected, as well as better than residents who did not elect to complete a genetics rotation. We suspect that the insufficient knowledge among physicians regarding a baseline genetics work-up is leading to redundant (i.e. concurrent karyotype and CMA) and incorrect (i.e. ordering CMA to detect achondroplasia) genetic testing and is contributing to rising health care costs in the United States. Our results provide specific teaching points upon which medical schools can focus education about clinical genetic testing and suggest that increased collaboration between primary care physicians and genetics professionals could benefit patient health care overall.

Quality of life and functional status in a low -income, multiethnic HIV -positive population

The introduction of new medical treatments in recent years, commonly referred to as highly active antiretroviral therapy, has greatly increased the survival of patients with HIV/AIDS. As patients with HIV/AIDS continue to live longer, other important health-related outcomes, such as quality of life (QOL), should be thoroughly studied. There is also evidence that racial/ethnic minorities are disproportionately affected by HIV/AIDS, but potential health disparities among individuals already infected with HIV/AIDS have not been adequately examined in ethnically diverse populations. The purpose of this dissertation was to: (1) examine the impact of both demographic and behavioral variables on functional status and overall QOL among a population of ethnically diverse and economically disadvantaged HIV/AIDS patients; (2) examine the psychometric properties of a functional status measure—the Household and Leisure Time Activities questionnaire (HLTA); and (3) assess a proximal-distal theoretical framework for QOL using a full structural equation model in a population of patients with HIV/AIDS. Analyses were performed using data collected in the fall of 2000 from the project, Health and Work-Related Quality of Life and Health Risk Behaviors in a Multiethnic HIV-positive Population . Investigators from The University of Texas M.D. Anderson Cancer Center, The University of Texas-Houston Medical School, and The University of Texas School of Public Health conducted this project. The study site was the Thomas Street Clinic (TSC), a comprehensive HIV/AIDS care facility funded by the Harris County Hospital District (HCHD). TSC provides HIV/AIDS care to a diverse population of approximately 4000 medically indigent residents of Harris County. A systematic, consecutive sampling procedure yielded a sample size of 348 patients. Findings suggested that overall QOL, work-role functioning, household functioning, and leisure time functioning were impaired in this patient population. Results from the psychometric evaluation indicated that the HLTA was a reliable and valid measure of household and leisure time functioning status in a low-income multiethnic HIV-positive population. Finally, structural equation modeling of the proximal-distal QOL model suggested that this model was not a viable representation of the relationship between the study variables in this patient population. ^

Optical detection of mealiness in apples using laser TDRS.

Mealiness is a textural attribute related to an internal fruit disorder that involves quality loss. It is characterised by the combination of abnormal softness of the fruit and absence of free juiciness in the mouth when eaten by the consumer. Recent research concluded with the development of precise instrumental procedure to measure a scale of mealiness based on the combination of several rheological properties and empirical magnitudes. In this line, time-domain laser reflectance spectroscopy (TDRS) is a new medical technology, used to characterise the optical properties of tissues, and to locate affected areas like tumours. Among its advantages compared to more traditional spectroscopic techniques, there is the feasibility to asses simultaneously and independently two optical parameters: the absorption of the light inside the irradiated body, and the scattering of the photons across the tissues, at each wavelength, generating two coefficients (µa, absorption coeff.; and µ's, transport scattering coeff.). If it is assumed that they are related respectively to chemical components and to physical properties of the sample, TDRS can be applied to the quantification of chemicals and the measurement of the rheological properties (i.e. mealiness estimation) at the same time. Using VIS & NIR lasers as light sources, TDRS was applied in this work to Golden Delicious and Cox apples (n=90), conforming several batches of untreated samples and storage-treated (20°C & 95%RH) to promote the development of mealiness. The collected database was clustered into different groups according to their instrumental test values (Barreiro et al, 1998). The optical coefficients were used as explanatory variables when building discriminant analysis functions for mealiness, achieving a classification score above 80% of correctly identified mealy versus fresh apples.

Providing health information to the general public: a survey of current practices in academic health sciences libraries*

A questionnaire was mailed to 148 publicly and privately supported academic health sciences libraries affiliated with Association of American Medical Colleges (AAMC)–accredited medical schools in the United States and Canada to determine level of access and services provided to the general public. For purposes of this study, “general public” was defined as nonaffiliated students or health care professionals, attorneys and other nonhealth-related professionals, patients from affiliated or other hospitals or clinics, and general consumers. One hundred five (71%) libraries responded. Results showed 98% of publicly supported libraries and 88% of privately supported libraries provided access to some or all of the general public. Publicly supported libraries saw greater numbers of public patrons, often provided more services, and were more likely to circulate materials from their collections than were privately supported libraries. A significant number of academic health sciences libraries housed a collection of consumer-oriented materials and many provided some level of document delivery service, usually for a fee. Most allowed the public to use some or all library computers. Results of this study indicated that academic health sciences libraries played a significant role in serving the information-seeking public and suggested a need to develop written policies or guidelines covering the services that will be provided to minimize the impact of this service on primary clientele.

Projecto na comunidade : uma experiência pedagógica extra-hospitalar no curso da Faculdade de Medicina de Lisboa

O ensino pré-graduado extra-hospitalar é uma necessidade há muito assumida pelas escolas de medicina do mundo desenvolvido. Na Faculdade de Medicina de Lisboa, pelo menos desde 1987, o centro de saúde tem sido utilizado como um espaço docente equivalente ao hospital. O «Projecto na Comunidade» ocorreu entre 1996 e 1998. A sua descrição e avaliação são aqui apresentadas.

O sistema PBL, problem-based learning, no ensino de medicina no Brasil : análise bibliográfica sobre a sua execução

Introdução: Entre as estratégias de ensino e aprendizagem utilizadas nas práticas pedagógicas, a Problem Based Learning (PBL) (Aprendizagem Baseada em Problemas) é utilizada desde 1960, em especial nos cursos de Medicina. Mesmo sendo uma estratégia valiosa, um dos seus obstáculos é a pouca prática dos alunos em atividades autodirigidas, pesquisa e construção coletiva do conhecimento. Objetivo: Rastrear elementos constitutivos da PBL através de dados colhidos em artigos pesquisados em sítios de divulgação científica; Avaliar, nos estudos selecionados, os aspectos positivos e negativos que estejam relacionados com a metodologia do Sistema PBL aplicada ao ensino médico no Brasil. Metodologia: Estudo bibliográfico de 13 textos utilizando um modelo de desconstrução, denominada Análise Textual Discursiva (ATD) que consiste em: transformação dos artigos em pedaços menores; análise textual; identificação de padrões convergentes e divergentes em relação a PBL; organização e síntese dos dados, culminando com a elaboração de estratégia adaptativa da PBL para o curso de Medicina. Resultados: Foram encontradas 116 citações que convergiam para referências positivos acerca da metodologia PBL e 40 citações que divergiam acerca dos pontos positivos. Os aspectos positivos como o desenvolvimento de atitudes e habilidades; desenvolvimento de competências anteriores ao curso; efeitos positivos depois de terminada a graduação, como autonomia de estudo e a articulação entre currículo e realidade profissional, representam pontos a serem reforçados na aula. Em contraponto, foi observado que dentre os negativos a não compreensão do papel do professor como tutor; necessidade de conteúdo formal tradicional pelos alunos e a expectativa que o professor retire as suas dúvidas são pontos a serem evitados. Conclusões: A metodologia PBL deverá servir como metodologia ativa para aproveitar ao máximo as habilidades que os alunos já apresentam, potencializando o aprendizado na educação médica em sala de aula. Palavras-Chave: PBL; curso de medicina; metodologia ativa; educação médica.

Émergence et développement de l’oncologie au Québec : collaboration, compétition et défis organisationnels, 1900-2005

Objectifs : le principal objectif de notre projet doctoral consiste à mettre en relief les transformations qui ont marqué le développement de l’oncologie et de la lutte contre le cancer au Québec au 20e siècle. Pour ce faire, nous nous sommes penchées sur trois niveaux d’analyse : 1) le niveau micro aborde l’organisation des services médicaux au sein d’une organisation hospitalière, soit l’Hôtel-Dieu de Québec. 2) Le niveau méso analyse une lutte professionnelle, soit la lutte entre les hématologues et les oncologues médicaux pour la reconnaissance de l’oncologie médicale. 3) Le niveau macro s’intéresse à l’organisation de la lutte contre le cancer à travers la province de Québec et aux différents modèles organisationnels créés. Principale hypothèse : l’émergence et la transformation de l’oncologie et de la lutte contre le cancer ont été influencées des rapports de collaboration et de compétition entre les acteurs impliqués en oncologie. En effet, il apparaît que ce champ se trouve en tension entre l’obligation de collaborer pour offrir des services de qualité aux patients et les dynamiques professionnelles et/ou organisationnelles. Cadre théorique : un cadre théorique a été développé pour chacun des niveaux d’analyse. Le niveau micro s’inspire des travaux de Frickel, Abbott et Strauss et s’intéresse plus particulièrement aux négociations entourant l’ordre social au sein d’un hôpital universitaire; le niveau méso emploie les travaux de Bourdieu et Abbott pour analyser la lutte entre deux spécialités médicales pour le contrôle des agents de chimiothérapie; et le niveau macro, de la sociologie des organisations et de la théorie néo-institutionnaliste pour mettre en relief l’émergence et la transformation de la lutte contre le cancer au Québec au 20e siècle. Méthodologie : l’approche de l’étude de cas a été adoptée et chaque niveau d’analyse constitue une étude de cas à part entière. Le corpus de données se compose de données archivistiques recueillies dans 10 centres d’archives canadiens, et de données d’entrevues. Une soixantaine d’entrevues avec des oncologues, des professionnels de la santé, des gestionnaires, des chercheurs et des fonctionnaires ont été réalisées. Conclusion : les différents niveaux d’analyse offrent différentes contributions qui leurs sont propres, mais l’ensemble de la thèse tend à mettre en relief la complexité du changement organisationnel à travers un perpétuel processus de définition et de redéfinition des frontières professionnelles et des organisations en raison du développement des connaissances scientifiques, des technologies, des expertises professionnelles et de l’environnement social, politique et économique.
