Which outcomes are most important to measure in patients with COVID-19 and how and when should these be measured? Development of an international standard set of outcomes measures for clinical use in patients with COVID-19: a report of the International Consortium for Health Outcomes Measurement (ICHOM) COVID-19 Working Group
Objectives: The COVID-19 pandemic has resulted in widespread morbidity and mortality with the consequences expected to be felt for many years. Significant variation exists in the care even of similar patients with COVID-19, including treatment practices within and between institutions. Outcome measures vary among clinical trials on the same therapies. Understanding which therapies are of most value is not possible unless consensus can be reached on which outcomes are most important to measure. Furthermore, consensus on the most important outcomes may enable patients to monitor and track their care, and may help providers to improve the care they offer through quality improvement. To develop a standardised minimum set of outcomes for clinical care, the International Consortium for Health Outcomes Measurement (ICHOM) assembled a working group (WG) of 28 volunteers, including health professionals, patients and patient representatives.
Design: A list of outcomes important to patients and professionals was generated from a systematic review of the published literature using the MEDLINE database, from review of outcomes being measured in ongoing clinical trials, from a survey distributed to patients and patient networks, and from previously published ICHOM standard sets in other disease areas. Using an online-modified Delphi process, the WG selected outcomes of greatest importance.
Results: The outcomes considered by the WG to be most important were selected and categorised into five domains: (1) functional status and quality of life, (2) mental functioning, (3) social functioning, (4) clinical outcomes and (5) symptoms. The WG identified demographic and clinical variables for use as case-mix risk adjusters. These included baseline demographics, clinical factors and treatment-related factors.
Conclusion: Implementation of these consensus recommendations could help institutions to monitor, compare and improve the quality and delivery of care to patients with COVID-19. Their consistent definition and collection could also broaden the implementation of more patient-centric clinical outcomes research

Recommendations for (Discontinuation of) Statin Treatment in Older Adults: Review of Guidelines
OBJECTIVES As a person's age increases and his/her health status declines, new challenges arise that may lead physicians to consider deprescribing statins. We aimed to provide insight into recommendations available in international cardiovascular disease prevention guidelines regarding discontinuation of statin treatment applicable to older adults. DESIGN We systematically searched PubMed, EMBASE, EMCARE, and the websites of guideline development organizations and online guideline repositories for cardiovascular disease prevention guidelines aimed at the general population. We selected all guidelines with recommendations (instructions and suggestions) on discontinuation of statin treatment applicable to older adults, published between January 2009 and April 2019. In addition, we performed a synthesis of information from all other recommendations for older adults regarding statin treatment. Methodological quality of the included guidelines was appraised using the appraisal of guidelines for research & evaluation II (AGREE II) instrument. RESULTS Eighteen international guidelines for cardiovascular disease prevention in the general adult population provided recommendations for statin discontinuation that were applicable to older adults. We identified three groups of instructions for statin discontinuation related to statin intolerance, and none was specifically aimed at older adults. Three guidelines also included suggestions to consider statin discontinuation in patients with poor health status. Of the 18 guidelines included, 16 made recommendations regarding statin treatment in older adults, although details on how to implement these recommendations in practice were not provided. CONCLUSION Current international cardiovascular disease prevention guidelines provide little specific guidance for physicians who are considering statin discontinuation in older adults in the context of declining health status and short life expectancy.Pathophysiology, epidemiology and therapy of agein
Environmental issues, interdisciplinarity, social theory and intellectual production in Latin America Tópicos ambientais, interdisciplinaridade, teoria social e produção intelectual na América Latina
While dealing with both interdisciplinarity and environment and society area as fields that harbor scientific contentions regarding ideas, practices, institutions and habitus (Bourdieu), this paper aims at providing an account of the multifaceted processes implied in the institutionalization of environmental concerns in Latin-American academia and research centers. The paper discusses the extent to which one can legitimately talk about "a Latin- American scientific specificity", supposedly resulting from peculiar theoretical approaches or even from particular socio-environmental features (such as widespread poverty and high rates of social inequality, along with unparalleled levels of biodiversity). Last but not least, the paper seeks to draw a sort of thematic map (via bibliographical review) as well as a consideration of the levels of scientific institutionalization of environmental issues in six different research centers located in Argentina, Chile, Mexico, Uruguay and Brazil.<br>Ao tratar a interdisciplinaridade e a área de ambiente e sociedade enquanto campos que lidam com questões científicas relacionadas com idéias, práticas, instituições e habitus (Bourdieu), esse artigo pretende contribuir para a compreensão dos processos multifacetados implicados na institucionalização da questão ambiental na academia e centros de pesquisa latino-americanos. O texto discute em que medida pode-se legitimamente falar de uma "especificidade científica latino-americana", supostamente resultante de abordagens teóricas peculiares ou mesmo de situações sócio-ambientais particulares (como pobreza e altas taxas de desigualdade, junto a incomparáveis índices de biodiversidade). Por último, mas também importante, o texto pretende trazer um panorama temático (através da revisão bibliográfica) assim como apontar os níveis de institucionalização científica da área ambiental em seis centros de pesquisa localizados na Argentina, Chile, México, Uruguai e Brasil
Managing genetic diversity and society needs
Most livestock are not indigenous to Brazil. Several animal species were considered domesticated in the pre-colonial period, since the indigenous people manage them as would be typical of European livestock production. For over 500 years there have been periodic introductions resulting in the wide range of genetic diversity that for centuries supported domestic animal production in the country. Even though these naturalized breeds have acquired adaptive traits after centuries of natural selection, they have been gradually replaced by exotic breeds, to such an extent, that today they are in danger of extinction To avoid further loss of this important genetic material, in 1983 Embrapa Genetic Resources and Biotechnology decided to include conservation of animal genetic resources among its priorities. In this paper we describe the effort to genetically characterize these populations, as a tool to ensure their genetic variability. To effectively save the threatened local breeds of livestock it is important to find a niche market for each one, reinserting them in production systems. They have to be utilized in order to be conserved. And there is no doubt that due to their adaptive traits, the Brazilian local breeds of livestock can play an important role in animal production, to meet society needs
ABC-SPH risk score for in-hospital mortality in COVID-19 patients : development, external validation and comparison with other available scores
The majority of available scores to assess mortality risk of coronavirus disease 2019 (COVID-19) patients in the emergency department have high risk of bias. Therefore, this cohort aimed to develop and validate a score at hospital admission for predicting in-hospital mortality in COVID-19 patients and to compare this score with other existing ones. Consecutive patients (≥ 18 years) with confirmed COVID-19 admitted to the participating hospitals were included. Logistic regression analysis was performed to develop a prediction model for in-hospital mortality, based on the 3978 patients admitted between March-July, 2020. The model was validated in the 1054 patients admitted during August-September, as well as in an external cohort of 474 Spanish patients. Median (25-75th percentile) age of the model-derivation cohort was 60 (48-72) years, and in-hospital mortality was 20.3%. The validation cohorts had similar age distribution and in-hospital mortality. Seven significant variables were included in the risk score: age, blood urea nitrogen, number of comorbidities, C-reactive protein, SpO/FiO ratio, platelet count, and heart rate. The model had high discriminatory value (AUROC 0.844, 95% CI 0.829-0.859), which was confirmed in the Brazilian (0.859 [95% CI 0.833-0.885]) and Spanish (0.894 [95% CI 0.870-0.919]) validation cohorts, and displayed better discrimination ability than other existing scores. It is implemented in a freely available online risk calculator (https://abc2sph.com/). An easy-to-use rapid scoring system based on characteristics of COVID-19 patients commonly available at hospital presentation was designed and validated for early stratification of in-hospital mortality risk of patients with COVID-19
