Dessa forma, buscou-se avaliar a inserção dessas competências essenciais neste programa. Trata-se de um estudo transversal, realizado de janeiro a abril de 2010, com cuidadores e pacientes assistidos pelo programa. Utilizaram-se formulários e diário de campo para a coleta de dados e posteriormente buscou-se avaliar as atividades exercidas no âmbito das competências essenciais preconizadas. Assim, foi possível perceber que as atribuições exercidas pelo programa ainda se encontram aquém do que é almejado, haja vista a lógica biomédica empregada, que conduziu à implementação parcial de Competências Essenciais como: Políticas de Saúde Pública; Planejamento e Implementação; Parceria, Colaboração e Apoio e Liderança. Tal fato denota a necessidade de maiores esforços governamentais e por parte dos profissionais envolvidos no programa com vistas à melhoria da atenção oferecida.

    Síndrome Coronariana Aguda (SCA) associada ao abuso de cocaína: uma revisão narrativa / Acute Coronary Syndrome (ACS) associated with cocaine abuse: a narrative review

    Get PDF
    Objetivo: Descrever o manejo do paciente com síndrome coronariana aguda (SCA) associada ao abuso de cocaína, com ênfase nos efeitos tóxicos da droga, no quadro clínico, no diagnóstico e no tratamento. Referencial bibliográfico: A cocaína é uma causa comum de complicações cardiovasculares no departamento de emergência. Isso decorre, em grande parte, devido a seus efeitos cardiotóxicos, que predispõem à isquemia miocárdica, tais como o aumento de fatores pró-coagulantes e o aumento da demanda do músculo cardíaco. Na apresentação clínica, o paciente usuário de cocaína com SCA manifesta a dor torácica como sintoma predominante, de forma similar ao não usuário. Porém, naquele que usou a cocaína, é mais frequente a presença de complicações associadas. Para a avaliação da dor, são solicitados o eletrocardiograma e os biomarcadores seriados, preferencialmente a troponina, como exames iniciais. Quanto ao tratamento, há divergências na literatura, principalmente, em relação ao uso de betabloqueadores nos usuários de cocaína, sendo as demais condutas para SCA aceitáveis, adicionando-se a estas, o uso de benzodiazepínicos. Considerações finais: A SCA induzida pelo uso da cocaína é uma patologia grave e exige mais estudos a respeito de seu tratamento, especialmente acerca da administração de betabloqueadores

    The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) has been in operation since July 2014. This paper describes the second data release from this phase, and the fourteenth from SDSS overall (making this, Data Release Fourteen or DR14). This release makes public data taken by SDSS-IV in its first two years of operation (July 2014-2016). Like all previous SDSS releases, DR14 is cumulative, including the most recent reductions and calibrations of all data taken by SDSS since the first phase began operations in 2000. New in DR14 is the first public release of data from the extended Baryon Oscillation Spectroscopic Survey (eBOSS); the first data from the second phase of the Apache Point Observatory (APO) Galactic Evolution Experiment (APOGEE-2), including stellar parameter estimates from an innovative data driven machine learning algorithm known as "The Cannon"; and almost twice as many data cubes from the Mapping Nearby Galaxies at APO (MaNGA) survey as were in the previous release (N = 2812 in total). This paper describes the location and format of the publicly available data from SDSS-IV surveys. We provide references to the important technical papers describing how these data have been taken (both targeting and observation details) and processed for scientific use. The SDSS website (www.sdss.org) has been updated for this release, and provides links to data downloads, as well as tutorials and examples of data use. SDSS-IV is planning to continue to collect astronomical data until 2020, and will be followed by SDSS-V.Comment: SDSS-IV collaboration alphabetical author data release paper.

    Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

    Full text link
    The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

    The question whether taxonomic descriptions naming new animal species without type specimen(s) deposited in collections should be accepted for publication by scientific journals and allowed by the Code has already been discussed in Zootaxa (Dubois & Nemésio 2007; Donegan 2008, 2009; Nemésio 2009a–b; Dubois 2009; Gentile & Snell 2009; Minelli 2009; Cianferoni & Bartolozzi 2016; Amorim et al. 2016). This question was again raised in a letter supported by 35 signatories published in the journal Nature (Pape et al. 2016) on 15 September 2016. On 25 September 2016, the following rebuttal (strictly limited to 300 words as per the editorial rules of Nature) was submitted to Nature, which on 18 October 2016 refused to publish it. As we think this problem is a very important one for zoological taxonomy, this text is published here exactly as submitted to Nature, followed by the list of the 493 taxonomists and collection-based researchers who signed it in the short time span from 20 September to 6 October 2016

    IMPORTANCE Overactivation of the renin-angiotensin system (RAS) may contribute to poor clinical outcomes in patients with COVID-19. Objective To determine whether angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) initiation improves outcomes in patients hospitalized for COVID-19. DESIGN, SETTING, AND PARTICIPANTS In an ongoing, adaptive platform randomized clinical trial, 721 critically ill and 58 non–critically ill hospitalized adults were randomized to receive an RAS inhibitor or control between March 16, 2021, and February 25, 2022, at 69 sites in 7 countries (final follow-up on June 1, 2022). INTERVENTIONS Patients were randomized to receive open-label initiation of an ACE inhibitor (n = 257), ARB (n = 248), ARB in combination with DMX-200 (a chemokine receptor-2 inhibitor; n = 10), or no RAS inhibitor (control; n = 264) for up to 10 days. MAIN OUTCOMES AND MEASURES The primary outcome was organ support–free days, a composite of hospital survival and days alive without cardiovascular or respiratory organ support through 21 days. The primary analysis was a bayesian cumulative logistic model. Odds ratios (ORs) greater than 1 represent improved outcomes. RESULTS On February 25, 2022, enrollment was discontinued due to safety concerns. Among 679 critically ill patients with available primary outcome data, the median age was 56 years and 239 participants (35.2%) were women. Median (IQR) organ support–free days among critically ill patients was 10 (–1 to 16) in the ACE inhibitor group (n = 231), 8 (–1 to 17) in the ARB group (n = 217), and 12 (0 to 17) in the control group (n = 231) (median adjusted odds ratios of 0.77 [95% bayesian credible interval, 0.58-1.06] for improvement for ACE inhibitor and 0.76 [95% credible interval, 0.56-1.05] for ARB compared with control). The posterior probabilities that ACE inhibitors and ARBs worsened organ support–free days compared with control were 94.9% and 95.4%, respectively. Hospital survival occurred in 166 of 231 critically ill participants (71.9%) in the ACE inhibitor group, 152 of 217 (70.0%) in the ARB group, and 182 of 231 (78.8%) in the control group (posterior probabilities that ACE inhibitor and ARB worsened hospital survival compared with control were 95.3% and 98.1%, respectively). CONCLUSIONS AND RELEVANCE In this trial, among critically ill adults with COVID-19, initiation of an ACE inhibitor or ARB did not improve, and likely worsened, clinical outcomes.

    Background The immunological escape of tumors represents one of the main ob- stacles to the treatment of malignancies. The blockade of PD-1 or CTLA-4 receptors represented a milestone in the history of immunotherapy. However, immune checkpoint inhibitors seem to be effective in specific cohorts of patients. It has been proposed that their efficacy relies on the presence of an immunological response. Thus, we hypothesized that disruption of the PD-L1/PD-1 axis would synergize with our oncolytic vaccine platform PeptiCRAd. Methods We used murine B16OVA in vivo tumor models and flow cytometry analysis to investigate the immunological background. Results First, we found that high-burden B16OVA tumors were refractory to combination immunotherapy. However, with a more aggressive schedule, tumors with a lower burden were more susceptible to the combination of PeptiCRAd and PD-L1 blockade. The therapy signifi- cantly increased the median survival of mice (Fig. 7). Interestingly, the reduced growth of contralaterally injected B16F10 cells sug- gested the presence of a long lasting immunological memory also against non-targeted antigens. Concerning the functional state of tumor infiltrating lymphocytes (TILs), we found that all the immune therapies would enhance the percentage of activated (PD-1pos TIM- 3neg) T lymphocytes and reduce the amount of exhausted (PD-1pos TIM-3pos) cells compared to placebo. As expected, we found that PeptiCRAd monotherapy could increase the number of antigen spe- cific CD8+ T cells compared to other treatments. However, only the combination with PD-L1 blockade could significantly increase the ra- tio between activated and exhausted pentamer positive cells (p= 0.0058), suggesting that by disrupting the PD-1/PD-L1 axis we could decrease the amount of dysfunctional antigen specific T cells. We ob- served that the anatomical location deeply influenced the state of CD4+ and CD8+ T lymphocytes. In fact, TIM-3 expression was in- creased by 2 fold on TILs compared to splenic and lymphoid T cells. In the CD8+ compartment, the expression of PD-1 on the surface seemed to be restricted to the tumor micro-environment, while CD4 + T cells had a high expression of PD-1 also in lymphoid organs. Interestingly, we found that the levels of PD-1 were significantly higher on CD8+ T cells than on CD4+ T cells into the tumor micro- environment (p < 0.0001). Conclusions In conclusion, we demonstrated that the efficacy of immune check- point inhibitors might be strongly enhanced by their combination with cancer vaccines. PeptiCRAd was able to increase the number of antigen-specific T cells and PD-L1 blockade prevented their exhaus- tion, resulting in long-lasting immunological memory and increased median survival

    Estudo da ativação do inflamassoma em células endoteliais de cordão umbilical humano (linhageam EA.hy926) durante a infecção experimental pelo vírus Zika

    Ministério da Saúde. Secretaria de Vigilância em Saúde. Instituto Evandro Chagas. Programa de Pós-Graduação em Virologia. Ananindeua, PA, Brasil.O vírus Zika (ZIKV) é um arbovírus pertencente à família Flaviviridae e ao gênero Flavivirus. A zika é uma doença febril aguda caracterizada por febre, erupção cutânea maculopapular, artralgia e edema de membros. Em 2015, quando chegou ao Brasil, o ZIKV causou a sua maior epidemia e surpreendeu pela habilidade de causar danos ao sistema nervoso central, incluindo um elevado número de casos de microcefalia no Nordeste do país. A patogenia induzida pelo ZIKV ainda não está esclarecida, bem como a sua interação com as células que compõem a interface materno-fetal. A resposta imune inata exerce importante função na determinação do curso da infecção viral e tem início com o reconhecimento de padrões virais e/ou danos celulares por receptores de reconhecimento de padrões resultando em resposta antiviral e inflamatória. A ativação do inflamassoma vem ganhando reconhecimento como um importante mecanismo de proteção diante das infecções virais. Assim, o presente estudo avaliou se o ZIKV é capaz de induzir a ativação do inflamassoma em cultura de células endoteliais de cordão umbilical humano (linhagem EA.hy926) através da detecção dos níveis de caspase-1. Células EA.hy926 foram infectadas utilizando dois isolados do ZIKV (BeH818305 e BeH815744) (MOI 0,01) e as análises foram realizadas nos períodos de 24, 36 e 48 horas pós-infecção. Como resultados observou-se considerável efeito citopático celular em 48 horas pós-infecção, aumento nos níveis de ativação de caspase-1 também em 48 horas pós-infecção pelo isolado viral BeH818305 e diminuição da viabilidade celular para ambos os vírus de forma tempo-dependente de infecção. Estudos adicionais são necessários para identificação dos receptores envolvidos e caracterização do perfil imunológico de resposta

    Stefania Paladini - ORCID: 0000-0002-1526-3589 https://orcid.org/0000-0002-1526-3589Item is not available in this repository.This paper investigates the relationship between periodontal disease and various cancer types. It provides a comprehensive overview of the existing knowledge about the interaction between periodontal disease and carcinogenesis, explores the underlying biological mechanisms of this connection, and consider the impact of these findings on healthcare practices and future research directions. Utilizing Systematic Literature Network Analysis, which combines bibliometric analysis with Systematic Literature Review, this study analyzes 164 documents from 2000 to 2023. Focus is placed on the 38 most globally cited papers, enabling a targeted and comprehensive analysis of the predominant research within this scope. This review highlights that colorectal, oral, pancreatic, lung, and gastrointestinal cancers have consistent associations with periodontal disease. On the other hand, hematological, breast and prostate cancers show associations with periodontal disease, but these links are less pronounced and more variable, indicating the need for targeted research in these domains. These insights emphasize the necessity for a multidisciplinary healthcare approach, recognizing the systemic implications of periodontal disease. © 2024 Elsevier Ltdhttps://doi.org/10.1016/j.canep.2024.10259591pubpu
