    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.DiffĂ©rents acteurs gouvernementaux et non gouvernementaux cherchent Ă  mobiliser des preuvesscientifiques pour soutenir les travaux sur les politiques publiques. Au cours des derniĂšres dĂ©cennies, des Ă©tudes ont mis l’accent sur les capacitĂ©s d’analyse du point de vue des individus – principalement des fonctionnaires et des gestionnaires de l’État – ou des organisations –structures ministĂ©rielles ou agences indĂ©pendantes. Cet article innove les enquĂȘtes prĂ©cĂ©dentes encherchant Ă  comprendre comment les dimensionsindividuelles et organisationnelles interagissent pourĂ©largir la mobilisation des preuves produites par lascience. La recherche a utilisĂ© une vaste enquĂȘte NauprĂšs des bureaucrates de l’administration publiquefĂ©dĂ©rale brĂ©silienne. Les rĂ©sultats indiquent que cesdeux dimensions interagissent positivement pourune plus grande utilisation des preuves scientifiques.Cependant, une attention particuliĂšre doit ĂȘtre accordĂ©e Ă  la façon dont les ressources organisationnelles sont conceptualisĂ©es et opĂ©rationnalisĂ©es. En tant qu’unitĂ© spĂ©cialisĂ©e, l’interaction avec la capacitĂ© d’identifier, decollecter et d’analyser des donnĂ©es et des informations liĂ©es Ă  la politique publique s’est avĂ©rĂ©e importante. En tant que ressource ou disponibilitĂ© organisationnelle, l’interaction avec l’éducation des individus s’est rĂ©vĂ©lĂ©e ĂȘtre une dimension pertinente. Enfin, en tant qu’opportunitĂ© de relation organisationnelle avec le milieu universitaire, l’interaction avec le niveau d’éducation formelle Ă©tait Ă©galement importante. Les recherches futures devraient chercher Ă  expliquer pourquoi d’autres formes d’interaction entre les capacitĂ©s individuelles et organisationnelles ne sont pas pertinentes, en plus de chercher Ă  comprendre les mĂ©canismes causaux qui expliquent les rĂ©sultats identifiĂ©s.Diferentes atores governamentais e nĂŁo governamentais buscam mobilizar evidĂȘncias cientĂ­ficas para subsidiar o trabalho em polĂ­ticas pĂșblicas. Nas Ășltimas dĂ©cadas, estudos tĂȘm enfatizado as capacidades analĂ­ticas do ponto de vista de indivĂ­duos - principalmente servidores pĂșblicos e gestores pĂșblicos - ou organizaçÔes - estruturas ministeriais ou ĂłrgĂŁos independentes. Este artigo inova investigaçÔes anteriores ao buscar compreender como as dimensĂ”es individual e organizacional interagem para ampliar a mobilização das evidĂȘncias produzidas pela ciĂȘncia. A pesquisa utilizou-se de um survey com extensa amostra de burocratas da administração pĂșblica federal brasileira. Os achados indicam que essas duas dimensĂ”es interagem positivamente para maior utilização das evidĂȘncias cientĂ­ficas. No entanto, atenção especial deve ser dada Ă  forma como as capacidades organizacionais sĂŁo conceituadas e operacionalizadas. Como unidade especializada, a interação com a capacidade de identificar, coletar e analisar dados e informaçÔes relacionados Ă  polĂ­tica pĂșblica mostrou-se importante. Como recurso ou disponibilidade organizacional, a interação com a educação dos indivĂ­duos revelou-se uma dimensĂŁo relevante. Por fim, como oportunidade organizacional de relacionamento com a academia, a interação com o nĂ­vel de educação formal tambĂ©m se mostrou significativa. Pesquisas futuras devem buscar explicar por que outras formas de interação entre capacidades individuais e organizacionais nĂŁo sĂŁo relevantes, alĂ©m de buscar compreender os mecanismos causais que explicam os achados identificados

    Get PDF
    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, BrasĂ­lia/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

    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 Ă© uma condição comum em pacientes graves. A transfusĂŁo de hemoderivados aumenta de forma significativa o risco de transmissĂŁo de agentes infecciosos e afeta o perfil imunolĂłgico. O objetivo deste estudo foi avaliar a incidĂȘncia de anemia e a prĂĄtica de transfusĂŁo de hemĂĄcias em UTI brasileiras. MÉTODO: Estudo prospectivo, multicĂȘntrico, realizado em 19 UTI em um perĂ­odo de duas semanas. A presença de anemia, as indicaçÔes e a utilização de concentrados de hemĂĄcias, foram avaliadas diariamente. As complicaçÔes que ocorreram durante a internação na UTI e apĂłs a transfusĂŁo da primeira unidade de concentrado de hemĂĄcias foram registradas. RESULTADOS: Um total de 33% apresentava anemia na admissĂŁo na UTI e esta proporção aumentou para 55% no final de sete dias de internação. Um total de 348 unidades de concentrado de hemĂĄcias foi transfundido em 86 pacientes (36,5%). A mĂ©dia de suas unidades por paciente foi 4,1 ± 3,3 U. O nĂ­vel de hemoglobina limiar para a transfusĂŁo de CH foi 7,7 ± 1,1 g/dL. Pacientes transfundidos tinham mais disfunçÔes orgĂąnicas avaliadas pelo escore SOFA (7,9 ± 4,6 versus 5,6 ± 3,8, transfundidos versus nĂŁo transfundidos, p < 0,05). As taxas de mortalidade foram 43,5% e 36,3% em pacientes transfundidos e nĂŁo transfundidos, respectivamente (RR 0,61-11,7, NS). Pacientes transfundidos tiveram nĂșmero maior de complicaçÔes (1,58 ± 0,66 versus 1,33 ± 0,49, p = 0,0001). CONCLUSÕES: A anemia Ă© comum em UTI brasileiras. O limiar transfusional de hemoglobina foi menor do que o observado em outros paises.Faculdade de Medicina de SĂŁo JosĂ© do Rio PretoUniversidade de SĂŁo PauloUFRGS Departamento de Medicina Interna HC de Porto AlegreUniversidade Paris VIUFRJ CTI dos Hospitais Cardiotrauma Ipanema e SĂŁo LucasAMIBUniversidade Estadual de LondrinaUFRGS FAMED HCPAFaculdade de Medicina de CatanduvaUNIFESP-EPMFundação Padre Albino UTI do Complexo HospitalarUniversidade Federal de SĂŁo Paulo (UNIFESP) Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSanta Casa de MisericĂłrdia de SĂŁo PauloHospital Unimed de LimeiraUTI do Hospital Regional de AssisAMIB Departamento de MedicinaAmerican CollegeFundação GetĂșlio VargasHospital PrĂł CardĂ­acoUNIRIOFGVHospital Santa Helena de GoiĂąniaHospital evangĂ©lico de Cachoeiro de Itapemirim Unidade coronarianaSBNHospital EvangĂ©lico Cachoeiro de Itapemirim UTI Adulto e CoronarianaUFRJUFRN Hospital Onofre Lopes UTIHospital Novo AtibaiaUNIFESP, EPMUNIFESP, Disciplina de Anestesiologia, Dor e Terapia Intensiva Setor de TerapiaSciEL

    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 evidĂȘncias cientĂ­ficas que as suportam, quanto ao diagnĂłstico e tratamento da CDC, com especial ĂȘnfase na base de racionalidade que a embasou. A DC no sĂ©culo XXI mantĂ©m padrĂŁo epidemiolĂłgico de endemicidade em 21 paĂ­ses da AmĂ©rica Latina. Investigadores e gestores de paĂ­ses endĂȘmicos e nĂŁo endĂȘmicos indigitam a necessidade de se adotarem polĂ­ticas abrangentes, de saĂșde pĂșblica, para controle eficaz da transmissĂŁo inter-humanos da infecção pelo T. cruzi, e obter-se nĂ­vel otimizado de atendimento aos indivĂ­duos jĂĄ infectados, com foco em oportunização diagnĂłstica e terapĂȘutica. Mecanismos patogĂȘnicos e fisiopatolĂłgicos da CDC foram revisitados apĂłs atualização aprofundada e ficou bem consolidada a noção de que necrose e fibrose sejam estimuladas pela persistĂȘncia parasitĂĄria tissular e reação imune adversa, como mecanismos fundamentais, coadjuvados por distĂșrbios autonĂŽmicos e microvasculares. Alguns deles recentemente constituĂ­ram alvos potenciais de terapĂȘuticas. A histĂłria natural das fases aguda e crĂŽnica foi revista, com realce para a transmissĂŁo oral, a forma indeterminada e as sĂ­ndromes crĂŽnicas. MetanĂĄlises recentes de estudos observacionais estimaram o risco de evolução a partir das formas aguda e indeterminada e de mortalidade apĂłs instalação da cardiomiopatia crĂŽnica. Condutas terapĂȘuticas aplicĂĄveis aos indivĂ­duos com a FIDC foram abordadas especificamente. Todos os mĂ©todos para detectar alteraçÔes estruturais e/ou funcionais com variadas tĂ©cnicas de imageamento cardĂ­aco tambĂ©m foram revisados, com recomendaçÔes de uso nos vĂĄrios cenĂĄrios clĂ­nicos. Estratificação de risco de mortalidade fundamentada no escore de Rassi, com estudos recentes de sua aplicação, foi complementada por mĂ©todos que detectam fibrose miocĂĄrdica. A metodologia atual para diagnĂłstico etiolĂłgico e as consequentes implicaçÔes do tratamento tripanossomicida mereceram enfoque abrangente e aprofundado. TambĂ©m o tratamento de pacientes em risco ou com insuficiĂȘncia cardĂ­aca, arritmias e eventos tromboembĂłlicos, baseado em recursos farmacolĂłgicos e complementares, recebeu especial atenção. CapĂ­tulos suplementares subsidiaram as condutas aplicĂĄveis a diversos contextos especiais, entre eles o da co-infecção por T. cruzi/HIV, risco durante cirurgias, em grĂĄvidas, na reativação da infecção apĂłs transplante cardĂ­acos, e outros.&nbsp;&nbsp;&nbsp; Por fim, dois capĂ­tulos de grande significado social, abordando a estruturação de serviços especializados para atendimento aos indivĂ­duos com a CDC, e revisando os conceitos de cardiopatia grave e suas implicaçÔes mĂ©dico-trabalhistas completaram esta diretriz.&nbsp

    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

    Get PDF
    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
