Disputed expertise and chaotic disinformation: COVID-19 and denialist physicians in Brazil.

This article aims to show how incorrect ideas about COVID-19 were promoted by physicians in Brazil, contributing to a catastrophic response at the cost of hundreds of thousands of lives, and to examine the implications of this episode for the social studies of science, technology and medicine. The literature on the relationship between science and society takes two broad approaches, which are sometimes at odds with each other: (i) there is a traditional critique of science that points to unsupported claims of certainty and thus undue interference in general human affairs; (ii) there are many examples of attempts to undermine reasonable scientific claims, when they clash with economic and/or political interests of certain groups. Navigating those extremes is particularly critical in situations in which accurate knowledge is necessary for intervening in people's lives, as is the case in health-related issues. Determining who has actual epistemic expertise is a key factor in solving this conundrum. This became painfully clear during the unfolding of the COVID-19 pandemic, which highlighted the uncertainties of science in guiding decisions being made in real time, and provided opportunities for many forms of disinformation and conspiracy theories that hampered public health measures and promoted useless or even dangerous "treatments". This article discusses an instructive example of such developments in the chaotic response to the pandemic challenge in Brazil, which saw, among other unfortunate situations, physicians aligned with the denialist federal government advocating for unproven - or proven as ineffective - treatments and disseminating unfounded doubts about vaccines. Presumed expertise on the basis of professional training clearly did not translate into actual expertise in the necessary domains to ascertain the validity of such claims and scientific advice was overridden by ideology.

[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.

[Danilo Perestrello and the psychosomatic medicine movement in Brazil: from theory to institutional acceptance]. / O movimento da medicina psicossomática no Brasil: a trajetória teórica e institucional de Danilo Perestrello.

In the 1950s, the psychosomatic medicine movement emerged in Brazil, led by psychiatrist and psychoanalyst Danilo Perestrello. This article analyzes the strategies developed to configure this proposal and establish this field of study. From the beginning, this movement was characterized by a plan to reformulate medicine based on psychoanalytic theory and obtain favorable reception in institutions. During his career, Perestrello published articles and books with the intention of establishing a new way of thinking among physicians and worked at strategic institutions. His withdrawal from professional work due to a serious illness in 1976 was a factor contributing to the fragmentation of the psychosomatic movement in Brazil.

Na década de 1950, surgia o movimento da medicina psicossomática no Brasil, tendo como protagonista o psiquiatra e psicanalista Danilo Perestrello. A configuração dessa proposta e a análise das estratégias construídas para a formação desse campo disciplinar são o objeto deste estudo. Desde o início, esse movimento foi marcado por um projeto teórico-institucional de refundação da medicina sobre bases psicanalíticas e de institucionalização. Em sua trajetória, Perestrello publicou artigos e livros que tinham como intuito formar um novo estilo de pensamento entre os médicos, bem como a ocupação de instituições estratégicas. Seu afastamento profissional, devido a uma grave doença em 1976, representou um fator desagregador do movimento psicossomático no contexto brasileiro.

Here we go again: the reemergence of anti-vaccine activism on the Internet.

This essay discusses the resurgence of anti-vaccine activism in recent years, based on relevant literature and the author's own experiences. After presenting possible reasons for the reemergence of such movements and their consequences, the author analyses the role of Internet-mediated communication in amplifying this discourse and making it less amenable to criticism, presenting some of the main arguments deployed by the anti-vaccine agents in their discussions. The text concludes with a draft of possible responses to this increasingly worrying phenomenon.

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.
