[From psychosomatic medicine to medical psychology: the theoretical and institutional trajectory of Julio de Mello Filho]. / Da medicina psicossomática à psicologia médica: a trajetória teórica e institucional de Julio de Mello Filho.

Studies on the causality of pathologies and the doctor/patient relationship based on psychoanalytic formulations received two denominations in Brazil: psychosomatic medicine and medical psychology. The physician and psychoanalyst Julio de Mello Filho took a leading role in this movement after the psychiatrist and psychoanalyst Danillo Perestrello was incapacitated by illness. This study investigates how the theoretical concepts of the psychosomatic movement were structured and the institutional strategies used to establish this discipline in Brazil. From an epistemological and historical point of view, the initial notion of transforming the hegemonic medical model was seen to lose force, followed by a shift in medical psychology as a field of health psychology.

Os estudos sobre as causalidades das patologias e da relação médico/paciente a partir de formulações psicanalíticas receberam duas denominações no Brasil: medicina psicossomática e psicologia médica. O médico e psicanalista Julio de Mello Filho assumiu o protagonismo dessa proposta a partir da doença incapacitante do psiquiatra e psicanalista Danillo Perestrello. A estruturação da concepção teórica do movimento psicossomático e as estratégias institucionais utilizadas para a consolidação desse campo disciplinar no cenário brasileiro são o objeto deste estudo. Por meio de um referencial epistemológico e histórico, conclui-se que a proposta inicial de transformação do modelo médico hegemônico perde força e observa-se um deslocamento da psicologia médica como um campo da psicologia da saúde.

Baby food industry interference with infant feeding international regulation-A case study on the standard for follow-up formula.

Introduction: Globally, first-food systems have changed and breastfeeding has decreased due to the increased growth in commercial breast milk substitute (BMS) consumption, which includes both follow-up and toddler formulas. These products are manufactured by a small number of corporate leaders in international BMS sales. Discussions for global regulation of these products take place in the Codex Alimentarius and are permeated by the strong participation of these corporations in the Codex committees. Objective: In the present study, the participation of the baby food industry in the review of the follow-up formula standard in the Codex Committee on Nutrition and Foods for Special Dietary Uses (CCNFSDU) was analyzed. Methods: The analysis of the CCNFSDU documents was based on the period from 2009 to 2019 and used quantitative and qualitative approaches. Compositional and participation data from country delegations and observer organizations on the representative profiles of the involved institutions and the baby food industry's involvement in this process were established systematically. Results: In total, 134 out of the 189 Codex Alimentarius member countries engaged in the standard review process, of which 28% were involved in the entire process. The private sector was present in 81% of the most assiduous member state delegations to the meetings. Furthermore, ~60% of the observer organizations involved in the review process were business associations representing industry interests. Moreover, the International Special Dietary Foods Industries was the only business association with observer status in the CCNFSDU that was specifically dedicated to representing the baby food industryduring the review process. Conclusion: These research results expand the body of evidence confirming the expressive and disproportionate participation of baby food industries and their representatives in the discussion processes within the scope of the CCNFSDU. However, studies investigating the Codex and the public documents of its respective committees are limited. Thus, this was the first study to analyze the influence of the baby food industry on BMS global regulatory compliance.

Science, health, and human rights.

A solid knowledge base is one of the necessary conditions to assure health as a human right. The contemporary source of such knowledge are the sciences at large, which however presents a problem, since the scientific enterprise can - and has been - a source of human rights violations as well. The field of social studies of science (STS) takes an iconoclast approach to the science, providing much needed criticism of its claims of authority. Recently, however, when attacks from multiple sources attempt to undermine perfectly reasonable scientific developments, the STS approach may not provide the adequate tools to deal with such challenge, especially with regard to health issues. This essay explores, with examples, ways in which the critical stance of STS may be compatible with a defense of proper scientific knowledge - in fact, helping to define what that actually means - without falling in the trap of scientism.

Analysis of the application of a deterministic routine for identifying multiple pregnancies on SINASC, Brazil. / Análise da aplicação de uma rotina determinística para a identificação de gestações múltiplas no Sistema de Informações sobre Nascidos Vivos.

OBJECTIVE: to evaluate the application of a deterministic routine for identifying multiple pregnancies on the Brazilian Live Birth Information System (SINASC). METHODS: SINASC data deduplication and linkage with the mortality database (fetal deaths) for Rio de Janeiro state for the period 2007-2008; we used a deterministic routine, using a key based on SINASC maternal and birth information, complemented by manual review. RESULTS: of the 433,874 SINASC records, 9,036 (2.1%) were classified as multiple pregnancy newborns; after implementing the routine, we reclassified 385 records as twins, and 286 as singletons; accuracy of multiple pregnancy information on the SINASC database was high (sensitivity=95.8%; specificity=99.9%); applying the routine without the manual review process increased sensitivity by 4.2%, with no significant change of specificity. CONCLUSION: despite the accuracy of information regarding multiple pregnancy held on SINASC, we suggest the use of this routine as an option for improving classification of twins.

Trying to make sense out of chaos: science, politics and the COVID-19 pandemic.

This essay discusses the proliferation of discourses about the COVID-19 pandemic, presenting the challenges both to science and public policies that such an information overload present, having Collins' sociology of expertise as a theoretical framework.

On health needs: the concept labyrinth.

This study aims to reflect on the intertwining of certain key ideas about what we call "health" within the hegemonic biomedical paradigm: health, disease, health needs, medicalization and medical-industrial complex. This reflection is based on the philosophical contributions of Heller and Wiggins on needs; on the discussion of some authors, especially Canguilhem, about health and illness; and Collins' sociology of expertise. After pointing out some of the conundrums that arise from the conceptual fluidity of the topics abovementioned, we present a path forward, based on Collins' proposals about the role of experts in political arguments, to resituate the discussion on health needs.

Maternal education and age: inequalities in neonatal death.

OBJECTIVE: Evaluate the interaction between maternal age and education level in neonatal mortality, as well as investigate the temporal evolution of neonatal mortality in each stratum formed by the combination of these two risk factors. METHODS: A nonconcurrent cohort study, resulting from a probabilistic relationship between the Mortality Information System and the Live Birth Information System. To investigate the risk of neonatal death we performed a logistic regression, with an odds ratio estimate for the combined variable of maternal education and age, as well as the evaluation of additive and multiplicative interaction. The neonatal mortality rate time series, according to maternal education and age, was estimated by the Joinpoint Regression program. RESULTS: The neonatal mortality rate in the period was 8.09‰ and it was higher in newborns of mothers with low education levels: 12.7‰ (adolescent mothers) and 12.4‰ (mother 35 years old or older). Low level of education, without the age effect, increased the chance of neonatal death by 25% (OR = 1.25, 95%CI 1.14-1.36). The isolated effect of age on neonatal death was higher for adolescent mothers (OR = 1.39, 95%CI 1.33-1.46) than for mothers aged ≥ 35 years (OR = 1.16, 95%CI 1.09-1.23). In the time-trend analysis, no age group of women with low education levels presented a reduction in the neonatal mortality rate for the period, as opposed to women with intermediate or high levels of education, where the reduction was significant, around 4% annually. CONCLUSIONS: Two more vulnerable groups - adolescents with low levels of education and older women with low levels of education - were identified in relation to the risk of neonatal death and inequality in reducing the mortality rate.

Accuracy of probabilistic and deterministic record linkage: the case of tuberculosis.

OBJECTIVE: To analyze the accuracy of deterministic and probabilistic record linkage to identify TB duplicate records, as well as the characteristics of discordant pairs. METHODS: The study analyzed all TB records from 2009 to 2011 in the state of Rio de Janeiro. A deterministic record linkage algorithm was developed using a set of 70 rules, based on the combination of fragments of the key variables with or without modification (Soundex or substring). Each rule was formed by three or more fragments. The probabilistic approach required a cutoff point for the score, above which the links would be automatically classified as belonging to the same individual. The cutoff point was obtained by linkage of the Notifiable Diseases Information System - Tuberculosis database with itself, subsequent manual review and ROC curves and precision-recall. Sensitivity and specificity for accurate analysis were calculated. RESULTS: Accuracy ranged from 87.2% to 95.2% for sensitivity and 99.8% to 99.9% for specificity for probabilistic and deterministic record linkage, respectively. The occurrence of missing values for the key variables and the low percentage of similarity measure for name and date of birth were mainly responsible for the failure to identify records of the same individual with the techniques used. CONCLUSIONS: The two techniques showed a high level of correlation for pair classification. Although deterministic linkage identified more duplicate records than probabilistic linkage, the latter retrieved records not identified by the former. User need and experience should be considered when choosing the best technique to be used. OBJETIVO: Analisar a acurácia das técnicas determinística e probabilística para identificação de registros duplicados de tuberculose, assim como as características dos pares discordantes. MÉTODOS: Foram analisados todos os registros de tuberculose no período de 2009 a 2011 do estado do Rio de Janeiro. Foi desenvolvido algoritmo para relacionamento determinístico, usando conjunto de 70 regras, a partir da combinação de fragmentos das variáveis-chave com ou sem modificações (Soundex ou substring). Cada regra era formada por três ou mais fragmentos. Para a abordagem probabilística, foi necessário estabelecer ponto de corte para o escore, acima do qual os links seriam classificados automaticamente como pertencentes ao mesmo indivíduo. O ponto de corte foi obtido por meio do relacionamento da base de dados Sistema de Informação de Agravos de Notificação - Tuberculose com ela mesma, posterior revisão manual e curvas ROC e precision-recall. Foram calculadas a sensibilidade e especificidade para análise de acurácia. RESULTADOS: A acurácia variou de 87,2% a 95,2% para sensibilidade e 99,8% a 99,9% para especificidade para as técnicas probabilística e determinística, respectivamente. A presença de valores faltantes para as variáveis-chave e o baixo percentual da medida de similaridade para o nome e data de nascimento foram os principais responsáveis pela não identificação dos registros do mesmo indivíduo pelas técnicas utilizadas. CONCLUSÕES: As duas técnicas apresentam alta concordância para a classificação como par. Apesar de a técnica determinística ter identificado mais registros duplicados que a probabilística, a segunda recuperou registros não identificados pela primeira. A necessidade e a experiência do usuário devem ser consideradas para a escolha da técnica a ser utilizada.

[Where Descartes got it right: the implications for science, biomedicine, and public health]. / Os acertos de Descartes: implicações para a ciência, biomedicina e saúde coletiva.

The "received view" of Descartes has shaped the image of a dualist thinker who radically separated mind and body and thus laid the foundations for a "divided modernity". Numerous epithets have been applied to Cartesian thinking, all of which now sound depreciative: mechanicism, determinism, and reductionism, among others. This article contends that Descartes was not the type of dualist that is normally assumed. Based on a rereading of two essential works (Discourse on Method and Metaphysical Meditations) and a dialogue with the new literature on the theme, we contend that overcoming the "received view" of Descartes can shed new light on discussions in (and of) the collective health field and highlight the so-called expanded health paradigm (including aspects beyond the biological or physiological, such as the psychological, social, economic, cultural, and political).

Going open source: some lessons learned from the development of OpenRecLink.

Record linkage is the process of identifying and merging records across different databases belonging to the same entity. The health sector is one of the pioneering areas of record linkage techniques applications. In 1998 we began the development of a software package, called RecLink that implemented probabilistic record linkage techniques. In this article we report the development of a new, open-source version of that program, now named OpenRecLink. The aim of this article is to present the main characteristics of the new version and some of the lessons learned during its development. The new version is a total rewrite of the program, based on three goals: (1) to migrate to a free and open source software (FOSS) platform; (2) to implement a multiplatform version; (3) to implement the support for internationalization. We describe the tools that we adopted, the process of development and some of the problems encountered.

[Evaluation of scientific production in different subareas of Public Health: limits of the current model and contributions to the debate]. / A avaliação da produção científica nas subáreas da Saúde Coletiva: limites do atual modelo e contribuições para o debate.

The aim of this study was to discuss the limits of the quantitative evaluation model for scientific production in Public Health. An analysis of the scientific production of professors from the various subareas of Public Health was performed for 2010-2012. Distributions of the mean annual score for professors were compared according to subareas. The study estimated the likelihood that 60% of the professors in the graduate studies programs scored P50 (Very Good) or higher in their area. Professors of Epidemiology showed a significantly higher median annual score. Graduate studies programs whose faculty included at least 60% of Epidemiology professors and fewer than 10% from the subarea Social and Human Sciences in Health were significantly more likely to achieve a "Very Good" classification. The observed inequalities in scientific production between different subareas of Public Health point to the need to rethink their evaluation in order to avoid reproducing iniquities that have harmful consequences for the field's diversity.

[Scientific output: quality assessment or an accountant's tale?]. / Produção científica: avaliação da qualidade ou ficção contábil?

Quality assessment of scientific output is based extensively (if not exclusively) on quantitative bibliometric indicators, despite mounting criticism. The reaction by the academic community has increased in recent years. After presenting a critical evaluation of this model, the article presents an alternative qualitative model oriented towards removing the excessive stimulus for the unbridled production of articles that make a dubious contribution to science. Criticism of the proposed model is presented and discussed.
