[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.

Informed consent for record linkage: a systematic review.

BACKGROUND: Record linkage is a useful tool for health research. Potential benefits aside, its use raises discussions on privacy issues, such as whether a written informed consent for access to health records and linkage should be obtained. The authors aim to systematically review studies that assess consent proportions to record linkage. METHODS: 8 databases were searched up to June 2011 to find articles which presented consent proportions to record linkage. The screening, eligibility and inclusion of articles were conducted by two independent reviewers. The authors carried out meta-regression, subgroup and sensitivity analyses to assess heterogeneity. RESULTS: Of the 141 studies identified, only 11 presented empirical consent proportions and were included in the systematic review. The consent proportion varied widely from 39% to 97%. Seven studies presented consent proportions of 88% or higher, one of 72%, and only three presented consented proportion equal to or lower than 53%. None of the studies' characteristics evaluated explained heterogeneity. CONCLUSION: The results of this review show that, in general, individuals tend to consent to the use of their data for record linkage, with exceptions in specific populations or minorities. The authors believe that this, as well as the cited literature, lends support to policies that, while keeping relevant ethical controls in place, do not require individual informed consent for each and every study that relies on secondary data.

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.

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.

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.

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.

The epistemological aspects in the historical works of Don Bates.

The object of this paper is to systematize an epistemological framework of analysis derived from Don Bates's extended essay "Medicine and The Soul of Science," and apply that framework to a number of problems connected to medical knowledge, addressed in previous research by the author. The paper also draws from Bates's earlier work, especially the two-part "Closing the Circle" on William Harvey and the reception of his ideas by his contemporaries, and from contrasting and comparing it to the work of philosophers and historians of science who tackled similar problems, most notably Ludwik Fleck, Thomas Kuhn, and Ian Hacking. The resulting framework is based on three main concepts: constructed coherencing, the unproblematic background knowledge (UBK), and the mechanical mind. The paper closes with an application of that framework to the discussion of knowledge in medicine and the definition of diseases.

The Charlson comorbidity index (CCI) for adjustment of hip fracture mortality in the elderly: analysis of the importance of recording secondary diagnoses.

This study evaluates the role of the number of secondary diagnoses for calculating the Charlson comorbidity index (CCI) in risk adjustment of the 90-day mortality rate after hip fracture surgical repair. Comorbidities were selected by reviewing the medical records of 390 patients 50 years of age or older in a teaching hospital in Rio de Janeiro from 1995 to 2000. Logistic regression models were fitted including the variables age, sex, and CCI. The CCI was calculated based on: (1) all patients' comorbidities; (2) only the comorbidity with the highest weight; and (3) a single randomly selected comorbidity. There was a gradient in the prediction of the CCI mortality rate when all comorbidities were used (OR = 6.53; 95%CI: 2.27-18.77, for scores >or= 3). The predictive capacity of the CCI was observed even when it was calculated using only one comorbidity: with the highest weight (OR = 2.83; 95%CI: 1.11-7.22); and randomly selected (OR = 2.90; 95%CI: 1.07-7.81). Using all comorbidities for CCI calculation is important. Severity indices based on a single comorbidity can be useful for risk adjustment procedures.

[Political, institutional, and organizational evaluation of primary health care with an emphasis on comprehensiveness]. / Avaliação da atenção básica pela ótica político-institucional e da organização da atenção com ênfase na integralidade.

This article presents part of the data from an evaluation of primary care, implemented as part of research funded by the Brazilian Ministry of Health in 2005. Thirty-one municipalities from the States of Minas Gerais and Espírito Santo comprised the study sample. Data collected with qualitative methods (interviews and documents) were summarized, with the production of a set of categorical variables. The article presents the distribution of values for the variables by municipality. The variables were submitted to correspondence analysis, which showed their internal validity. The article also provides observations on relevant aspects of the field. In conclusion, the evaluation demonstrates advances in the Family Health Strategy in Brazil, with important contributions to the Project for Expansion and Consolidation of the Family Health Strategy, despite persistent obstacles, particularly related to human resources in the family health strategies and local use of the data produced.

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.

[Risk adjustment measures for mortality after hip fracture]. / Aplicação de medidas de ajuste de risco para a mortalidade após fratura proximal de fêmur.

OBJECTIVE: To assess factors associated to mortality in patients with hip fracture and to describe different risk adjustment measures. METHODS: Non-concurrent cohort study comprising 390 patients aged 50 years and more. Patients were identified from the Brazilian Unified Health System Hospital Information System, admitted for hip fracture surgery in a teaching hospital in Rio de Janeiro, southeastern Brazil, between 1995 and 2000. Data from medical records were collected and analyzed by logistic regression models to study 90-day mortality odds after admission according to patient and treatment profiles. Severity of illness classification indexes were estimated. RESULTS: Mortality rate was 7.4% and factors affecting mortality were age (OR=1.06; 95% CI: 1.02;1.11), number of co-morbidities (OR=1.44; 95% CI: 1.12;1.69), Charlson co-morbidity index (OR=6.67; 95% CI: 2.98;22.16) and time to surgery (OR=1.04; 95% CI: 1.02;1.07). CONCLUSIONS: Number of co-morbidities and Charlson co-morbidity index helped predicting the mortality rate.

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.
