A CIÊNCIA ENTRE INDIVÍDUOS E ORGANIZAÇÕES: como capacidades analíticas individuais e organizacionais se combinam para a utilização de evidências científicas nas políticas públicas?

Different governmental and non-governmentalactors seek to mobilize scientific evidence to supportwork on public policies. In recent decades, studieshave emphasized analytical capacities from thepoint of view of individuals – mainly public servantsand government managers – or organizations –ministerial structures or independent agencies. Thisarticle innovates previous investigations in seekingto understand how individual and organizationaldimensions interact to expand the mobilizationof evidence produced by science. The researchused an extensive N survey with bureaucratsfrom the Brazilian federal public administration.The findings indicate that these two dimensionsinteract positively for greater use of scientificevidence. However, special attention must be paidto how organizational resources are conceptualizedand operationalized. As a specialized unit, theinteraction with the ability to identify, collect andanalyze data and information related to publicpolicy proved to be important. As a resource ororganizational availability, the interaction with theeducation of individuals proved to be a relevantdimension. Finally, as an organizational relationshipopportunity with academia, the interaction with thelevel of formal education was also significant. Futureresearch should seek to explain why other forms ofinteraction between individual and organizationalcapabilities are not relevant, in addition to seekingto understand the causal mechanisms that explainthe identified findings.Différents acteurs gouvernementaux et non gouvernementaux cherchent à mobiliser des preuvesscientifiques pour soutenir les travaux sur les politiques publiques. Au cours des dernières décennies, des études ont mis l’accent sur les capacités d’analyse du point de vue des individus – principalement des fonctionnaires et des gestionnaires de l’État – ou des organisations –structures ministérielles ou agences indépendantes. Cet article innove les enquêtes précédentes encherchant à comprendre comment les dimensionsindividuelles et organisationnelles interagissent pourélargir la mobilisation des preuves produites par lascience. La recherche a utilisé une vaste enquête Nauprès des bureaucrates de l’administration publiquefédérale brésilienne. Les résultats indiquent que cesdeux dimensions interagissent positivement pourune plus grande utilisation des preuves scientifiques.Cependant, une attention particulière doit être accordée à la façon dont les ressources organisationnelles sont conceptualisées et opérationnalisées. En tant qu’unité spécialisée, l’interaction avec la capacité d’identifier, decollecter et d’analyser des données et des informations liées à la politique publique s’est avérée importante. En tant que ressource ou disponibilité organisationnelle, l’interaction avec l’éducation des individus s’est révélée être une dimension pertinente. Enfin, en tant qu’opportunité de relation organisationnelle avec le milieu universitaire, l’interaction avec le niveau d’éducation formelle était également importante. Les recherches futures devraient chercher à expliquer pourquoi d’autres formes d’interaction entre les capacités individuelles et organisationnelles ne sont pas pertinentes, en plus de chercher à comprendre les mécanismes causaux qui expliquent les résultats identifiés.Diferentes atores governamentais e não governamentais buscam mobilizar evidências científicas para subsidiar o trabalho em políticas públicas.

Epidemiological profile of patients with skin cancer treated at the Regional Hospital of Asa Norte/DF - Brazil

Introduction: Skin cancer is the most common neoplasm in the Brazilian population, corresponding to 30% of all malignant tumors registered in the country. Non-melanoma malignant tumors are the type of cancer with the highest incidence and prevalence in Brazil. Basal cell carcinoma (BCC) is the most common, accounting for between 70% and 75% of cases. Squamous cell carcinoma (SCC) accounts for 20% of cases. The objective is to determine the epidemiological profile, the types and subtypes found in the histopathological results, the surgical conduct and its effectiveness in patients with a suspected malignant skin lesion. Methods: A retrospective descriptive study, based on the analysis of electronic medical records for resection of skin lesions suspected of malignancy, carried out by the Plastic Surgery team at the Regional Hospital of Asa Norte, Brasília/DF, from January 2012 to December 2016. Results: 533 patients were submitted to surgery, being female (51.6%), with a mean age of 68.97 years and 84% diagnosed with basal cell carcinoma with solid subtype. The compromised margins reached 11% of the sample. The most prevalent reconstructions were primary closure and local flaps. Conclusion: The epidemiological profile of patients treated with lesions suspected of skin cancer showed prevalence in women over 60 years with a history of sun exposure. The face was the most affected site, the nose being the most common topography. BCC is the most common type, and the circumscribed solid subtype was the most prevalent. The most used type of reconstruction was primary closure and local flap

Transfusion practices in brazilian Intensive Care Units (pelo FUNDO-AMIB)

BACKGROUND AND OBJECTIVES: Anemia of critical illness is a multifactorial condition caused by blood loss, frequent phlebotomies and inadequate production of red blood cells (RBC). Controversy surrounds the most appropriate hemoglobin concentration trigger for transfusion of RBC. We aimed to evaluate transfusion practices in Brazilian ICUs. METHODS: A prospective study throughout a 2-week period in 19 Brazilian ICUs. Hemoglobin (Hb) level, transfusion rate, organ dysfunction assessment and 28-day mortality were evaluated. Primary indication for transfusion and pretransfusion hemoglobin level were collected for each transfusion. RESULTS: Two hundred thirty-one patients with an ICU length of stay longer than 48h were included. An Hb level lower than 10 g/dL was found in 33% on admission in the ICU. A total of 348 RBC units were transfused in 86 patients (36.5%). The mean pretransfusion hemoglobin level was 7.7 ± 1.1 g/dL. Transfused-patients had significantly higher SOFA score (7.9 ± 4.6 vs 5.6 ± 3.8, p < 0.05, respectively), days on mechanical ventilation (10.7 ± 8.2 vs 7.2 ± 6.4, p < 0.05) and days on vasoactive drugs (6.7 ± 6.4 vs 4.2 ± 4.0, p < 0.05) than non-transfused patients despite similar APACHE II scores (15.2 ± 8.1 vs 14.2 ± 8.1, NS). Transfused patients had higher mortality rate (43.5%) than non-transfused patients (36.3%) (RR 0.60-1.15, NS). Only one patient (0.28%) had febrile non-hemolytic transfusion and urticarial reactions. CONCLUSIONS: Anemia is common in critically ill patients.It seems from the present study that transfusion practices in Brazil have had a more restrictive approach with a lower limit transfusion trigger.JUSTIFICATIVA E OBJETIVOS: A anemia é uma condição comum em pacientes graves. A transfusão de hemoderivados aumenta de forma significativa o risco de transmissão de agentes infecciosos e afeta o perfil imunológico. O objetivo deste estudo foi avaliar a incidência de anemia e a prática de transfusão de hemácias em UTI brasileiras. MÉTODO: Estudo prospectivo, multicêntrico, realizado em 19 UTI em um período de duas semanas. A presença de anemia, as indicações e a utilização de concentrados de hemácias, foram avaliadas diariamente. As complicações que ocorreram durante a internação na UTI e após a transfusão da primeira unidade de concentrado de hemácias foram registradas. RESULTADOS: Um total de 33% apresentava anemia na admissão na UTI e esta proporção aumentou para 55% no final de sete dias de internação. Um total de 348 unidades de concentrado de hemácias foi transfundido em 86 pacientes (36,5%). A média de suas unidades por paciente foi 4,1 ± 3,3 U. O nível de hemoglobina limiar para a transfusão de CH foi 7,7 ± 1,1 g/dL. Pacientes transfundidos tinham mais disfunções orgânicas avaliadas pelo escore SOFA (7,9 ± 4,6 versus 5,6 ± 3,8, transfundidos versus não transfundidos, p < 0,05). As taxas de mortalidade foram 43,5% e 36,3% em pacientes transfundidos e não transfundidos, respectivamente (RR 0,61-11,7, NS). Pacientes transfundidos tiveram número maior de complicações (1,58 ± 0,66 versus 1,33 ± 0,49, p = 0,0001). CONCLUSÕES: A anemia é comum em UTI brasileiras. O limiar transfusional de hemoglobina foi menor do que o observado em outros paises.Faculdade de Medicina de São José do Rio PretoUniversidade de São PauloUFRGS Departamento de Medicina Interna HC de Porto AlegreUniversidade Paris VIUFRJ CTI dos Hospitais Cardiotrauma Ipanema e São LucasAMIBUniversidade Estadual de LondrinaUFRGS FAMED HCPAFaculdade de Medicina de CatanduvaUNIFESP-EPMFundação Padre Albino UTI do Complexo HospitalarUniversidade Federal de São Paulo (UNIFESP) Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSanta Casa de Misericórdia de São PauloHospital Unimed de LimeiraUTI do Hospital Regional de AssisAMIB Departamento de MedicinaAmerican CollegeFundação Getúlio VargasHospital Pró CardíacoUNIRIOFGVHospital Santa Helena de GoiâniaHospital evangélico de Cachoeiro de Itapemirim Unidade coronarianaSBNHospital Evangélico Cachoeiro de Itapemirim UTI Adulto e CoronarianaUFRJUFRN Hospital Onofre Lopes UTIHospital Novo AtibaiaUNIFESP, EPMUNIFESP, Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSciEL

Diretriz da Sociedade Brasileira de Cardiologia sobre Diagnóstico e Tratamento de Pacientes com Cardiomiopatia da Doença de Chagas

This guideline aimed to update the concepts and formulate the standards of conduct and scientific evidence that support them, regarding the diagnosis and treatment of the Cardiomyopathy of Chagas disease, with special emphasis on the rationality base that supported it.&nbsp; Chagas disease in the 21st century maintains an epidemiological pattern of endemicity in 21 Latin American countries. Researchers and managers from endemic and non-endemic countries point to the need to adopt comprehensive public health policies to effectively control the interhuman transmission of T. cruzi infection, and to obtain an optimized level of care for already infected individuals, focusing on diagnostic and therapeutic opportunistic opportunities. &nbsp; Pathogenic and pathophysiological mechanisms of the Cardiomyopathy of Chagas disease were revisited after in-depth updating and the notion that necrosis and fibrosis are stimulated by tissue parasitic persistence and adverse immune reaction, as fundamental mechanisms, assisted by autonomic and microvascular disorders, was well established. Some of them have recently formed potential targets of therapies.&nbsp; The natural history of the acute and chronic phases was reviewed, with enhancement for oral transmission, indeterminate form and chronic syndromes. Recent meta-analyses of observational studies have estimated the risk of evolution from acute and indeterminate forms and mortality after chronic cardiomyopathy. Therapeutic approaches applicable to individuals with Indeterminate form of Chagas disease were specifically addressed. All methods to detect structural and/or functional alterations with various cardiac imaging techniques were also reviewed, with recommendations for use in various clinical scenarios. Mortality risk stratification based on the Rassi score, with recent studies of its application, was complemented by methods that detect myocardial fibrosis.&nbsp; The current methodology for etiological diagnosis and the consequent implications of trypanonomic treatment deserved a comprehensive and in-depth approach. Also the treatment of patients at risk or with heart failure, arrhythmias and thromboembolic events, based on pharmacological and complementary resources, received special attention. Additional chapters supported the conducts applicable to several special contexts, including t. cruzi/HIV co-infection, risk during surgeries, in pregnant women, in the reactivation of infection after heart transplantation, and others.&nbsp; &nbsp;&nbsp; Finally, two chapters of great social significance, addressing the structuring of specialized services to care for individuals with the Cardiomyopathy of Chagas disease, and reviewing the concepts of severe heart disease and its medical-labor implications completed this guideline.Esta diretriz teve como objetivo principal atualizar os conceitos e formular as normas de conduta e evidências científicas que as suportam, quanto ao diagnóstico e tratamento da CDC, com especial ênfase na base de racionalidade que a embasou. A DC no século XXI mantém padrão epidemiológico de endemicidade em 21 países da América Latina. Investigadores e gestores de países endêmicos e não endêmicos indigitam a necessidade de se adotarem políticas abrangentes, de saúde pública, para controle eficaz da transmissão inter-humanos da infecção pelo T. cruzi, e obter-se nível otimizado de atendimento aos indivíduos já infectados, com foco em oportunização diagnóstica e terapêutica. Mecanismos patogênicos e fisiopatológicos da CDC foram revisitados após atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistência parasitária tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distúrbios autonômicos e microvasculares. Alguns deles recentemente constituíram alvos potenciais de terapêuticas. A história natural das fases aguda e crônica foi revista, com realce para a transmissão oral, a forma indeterminada e as síndromes crônicas. Metanálises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade após instalação da cardiomiopatia crônica. Condutas terapêuticas aplicáveis aos indivíduos com a FIDC foram abordadas especificamente. Todos os métodos para detectar alterações estruturais e/ou funcionais com variadas técnicas de imageamento cardíaco também foram revisados, com recomendações de uso nos vários cenários clínicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por métodos que detectam fibrose miocárdica. A metodologia atual para diagnóstico etiológico e as consequentes implicações do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. Também o tratamento de pacientes em risco ou com insuficiência cardíaca, arritmias e eventos tromboembólicos, baseado em recursos farmacológicos e complementares, recebeu especial atenção. Capítulos suplementares subsidiaram as condutas aplicáveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grávidas, na reativação da infecção após transplante cardíacos, e outros.&nbsp;&nbsp;&nbsp; Por fim, dois capítulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivíduos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicações médico-trabalhistas completaram esta diretriz.&nbsp

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio

NEOTROPICAL XENARTHRANS: a data set of occurrence of xenarthran species in the Neotropics

Xenarthrans – anteaters, sloths, and armadillos – have essential functions for ecosystem maintenance, such as insect control and nutrient cycling, playing key roles as ecosystem engineers. Because of habitat loss and fragmentation, hunting pressure, and conflicts with 24 domestic dogs, these species have been threatened locally, regionally, or even across their full distribution ranges. The Neotropics harbor 21 species of armadillos, ten anteaters, and six sloths. Our dataset includes the families Chlamyphoridae (13), Dasypodidae (7), Myrmecophagidae (3), Bradypodidae (4), and Megalonychidae (2). We have no occurrence data on Dasypus pilosus (Dasypodidae). Regarding Cyclopedidae, until recently, only one species was recognized, but new genetic studies have revealed that the group is represented by seven species. In this data-paper, we compiled a total of 42,528 records of 31 species, represented by occurrence and quantitative data, totaling 24,847 unique georeferenced records. The geographic range is from the south of the USA, Mexico, and Caribbean countries at the northern portion of the Neotropics, to its austral distribution in Argentina, Paraguay, Chile, and Uruguay. Regarding anteaters, Myrmecophaga tridactyla has the most records (n=5,941), and Cyclopes sp. has the fewest (n=240). The armadillo species with the most data is Dasypus novemcinctus (n=11,588), and the least recorded for Calyptophractus retusus (n=33). With regards to sloth species, Bradypus variegatus has the most records (n=962), and Bradypus pygmaeus has the fewest (n=12). Our main objective with Neotropical Xenarthrans is to make occurrence and quantitative data available to facilitate more ecological research, particularly if we integrate the xenarthran data with other datasets of Neotropical Series which will become available very soon (i.e. Neotropical Carnivores, Neotropical Invasive Mammals, and Neotropical Hunters and Dogs). Therefore, studies on trophic cascades, hunting pressure, habitat loss, fragmentation effects, species invasion, and climate change effects will be possible with the Neotropical Xenarthrans dataset

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection
