CARACTERÍSTICAS ORGANIZACIONAIS DA VIGILÂNCIA SANITÁRIA MUNICIPAL E SUA RELAÇÃO COM OS INDICADORES DE SAÚDE

Este estudo objetivou verificar em que medida as características organizacionais da vigilância sanitária municipal (VISAM) de Goiás e algumas variáveis socioeconômicas dos municípios se relacionam com indicadores de saúde, medidos pelo coeficiente de detecção média anual de doenças de notificação compulsória confirmadas nos municípios estudados no período 2006-2010. Participaram 53 gestores e 335 fiscais trabalhadores da VISAM nos 53 municípios selecionados a partir de critérios preestabelecidos. Os dados primários foram obtidos através de questionários, construídos e validados para atender aos objetivos da pesquisa, e os secundários por meios dos sistemas públicos e de arquivos gerados especificamente para a finalidade do estudo. No tratamento estatístico utilizou-se o programa SPSS (Statistical Package for the Social Sciences) for Windows e envolveu análises descritivas, correlacionais e de variância. Algumas características organizacionais da VISAM foram associadas com o coeficiente de detecção das doenças investigadas. As deficiências estruturais e organizacionais existentes no setor sugerem ineficiências na atuação da VISAM no processo de prevenção das doenças e agravos, que podem contribuir para o aumento das subnotificações dentro do Sistema de Vigilância em Saúde. Superar as deficiências estruturais e organizacionais poderá contribuir para o fortalecimento da gestão, gerenciamento efetivo do risco sanitário e melhorias nos indicadores de saúde. &nbsp

Modelling the spatial risk of malaria through probability distribution of Anopheles maculipennis s.l. and imported cases

Malaria remains one of the most important infectious diseases globally due to its high incidence and mortality rates. The influx of infected cases from endemic to non-endemic malaria regions like Europe has resulted in a public health concern over sporadic local outbreaks. This is facilitated by the continued presence of competent Anopheles vectors in non-endemic countries. We modelled the potential distribution of the main malaria vector across Spain using the ensemble of eight modelling techniques based on environmental parameters and the Anopheles maculipennis s.l. presence/absence data collected from 2000 to 2020. We then combined this map with the number of imported malaria cases in each municipality to detect the geographic hot spots with a higher risk of local malaria transmission. The malaria vector occurred preferentially in irrigated lands characterized by warm climate conditions and moderate annual precipitation. Some areas surrounding irrigated lands in northern Spain (e.g. Zaragoza, Logroño), mainland areas (e.g. Madrid, Toledo) and in the South (e.g. Huelva), presented a significant likelihood of A. maculipennis s.l. occurrence, with a large overlap with the presence of imported cases of malaria. While the risk of malaria re-emergence in Spain is low, it is not evenly distributed throughout the country. The four recorded local cases of mosquito-borne transmission occurred in areas with a high overlap of imported cases and mosquito presence. Integrating mosquito distribution with human incidence cases provides an effective tool for the quantification of large-scale geographic variation in transmission risk and pinpointing priority areas for targeted surveillance and prevention

Relación de los centros educativos de enseñanza secundaria con el entorno en Iberoamérica

La presente aportación recoge la visión de 46 especialistas de trece países iberoamericanos sobre las formas de entender y promover la relación de los centros educativos con el entorno. Situados en la enseñanza secundaria (y en la franja de edad de 15 a 18 años), se trata de delimitar la manera cómo se conecta la vida interna y la vida externa del centro educativo, presentando los modelos que se utilizan, las estrategias de intervención y las experiencias más significativas en cada uno de los países. Las aportaciones no buscan tanto revisar la vinculación de los centros educativos entre sí como de analizar fundamentalmente las vinculaciones con la comunidad y las organizaciones que acoge (asociaciones, empresas, organizaciones gubernamentales o no gubernamentales significativas,…). Al respecto, una parte de los escritos recogen experiencias y estrategias que concretan la relación que estudiamos. Esperamos sea así un apoyo para los estudiosos de la temática, pero también aporte contenidos que ayuden a los directivos a mejorar su gestión de las relaciones externas. La orientación de los escritos al análisis organizativo y a la función de los directivos como promotores de las relación con la comunidad tiene que ver con las finalidades y objetivos de la RedAGE; también con el convencimiento por parte de los que escriben que la ordenación que se haga del contexto de intervención y la actuación de los directivos es fundamental para obtener y mantener las respuestas más idóneas a las exigencias del medio socio-cultural-económico. Su realización se vincula al encuentro de especialistas de la RedAGE realizado en el mes de marzo de 2013 en La Paz. Allí, los representantes de las organizaciones miembro presentaron y debatieron, durante el mismo, documentos sobre la temática de la vinculación escuela y entorno, en sus respectivos países, que constituyen la base sobre la que se han realizado las aportaciones definitivas que recoge el presente texto. Se cubre así y de nuevo un propósito fundamental de la Red AGE, como es el de fomentar el intercambio de experiencias, la promoción del conocimiento sobre administración y gestión educativa y la reflexión sobre la práctica de la gestión. La finalidad última es la de mejorar el funcionamiento de los centros educativos (y, a través de ellos, de los sistemas educativos), procurando sean de calidad y un instrumento para el cambio profesional y social

Socializing One Health: an innovative strategy to investigate social and behavioral risks of emerging viral threats

In an effort to strengthen global capacity to prevent, detect, and control infectious diseases in animals and people, the United States Agency for International Development’s (USAID) Emerging Pandemic Threats (EPT) PREDICT project funded development of regional, national, and local One Health capacities for early disease detection, rapid response, disease control, and risk reduction. From the outset, the EPT approach was inclusive of social science research methods designed to understand the contexts and behaviors of communities living and working at human-animal-environment interfaces considered high-risk for virus emergence. Using qualitative and quantitative approaches, PREDICT behavioral research aimed to identify and assess a range of socio-cultural behaviors that could be influential in zoonotic disease emergence, amplification, and transmission. This broad approach to behavioral risk characterization enabled us to identify and characterize human activities that could be linked to the transmission dynamics of new and emerging viruses. This paper provides a discussion of implementation of a social science approach within a zoonotic surveillance framework. We conducted in-depth ethnographic interviews and focus groups to better understand the individual- and community-level knowledge, attitudes, and practices that potentially put participants at risk for zoonotic disease transmission from the animals they live and work with, across 6 interface domains. When we asked highly-exposed individuals (ie. bushmeat hunters, wildlife or guano farmers) about the risk they perceived in their occupational activities, most did not perceive it to be risky, whether because it was normalized by years (or generations) of doing such an activity, or due to lack of information about potential risks. Integrating the social sciences allows investigations of the specific human activities that are hypothesized to drive disease emergence, amplification, and transmission, in order to better substantiate behavioral disease drivers, along with the social dimensions of infection and transmission dynamics. Understanding these dynamics is critical to achieving health security--the protection from threats to health-- which requires investments in both collective and individual health security. Involving behavioral sciences into zoonotic disease surveillance allowed us to push toward fuller community integration and engagement and toward dialogue and implementation of recommendations for disease prevention and improved health security

Retrospective evaluation of whole exome and genome mutation calls in 746 cancer samples

Funder: NCI U24CA211006Abstract: The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) curated consensus somatic mutation calls using whole exome sequencing (WES) and whole genome sequencing (WGS), respectively. Here, as part of the ICGC/TCGA Pan-Cancer Analysis of Whole Genomes (PCAWG) Consortium, which aggregated whole genome sequencing data from 2,658 cancers across 38 tumour types, we compare WES and WGS side-by-side from 746 TCGA samples, finding that ~80% of mutations overlap in covered exonic regions. We estimate that low variant allele fraction (VAF < 15%) and clonal heterogeneity contribute up to 68% of private WGS mutations and 71% of private WES mutations. We observe that ~30% of private WGS mutations trace to mutations identified by a single variant caller in WES consensus efforts. WGS captures both ~50% more variation in exonic regions and un-observed mutations in loci with variable GC-content. Together, our analysis highlights technological divergences between two reproducible somatic variant detection efforts

The evolving SARS-CoV-2 epidemic in Africa: Insights from rapidly expanding genomic surveillance

INTRODUCTION Investment in Africa over the past year with regard to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) sequencing has led to a massive increase in the number of sequences, which, to date, exceeds 100,000 sequences generated to track the pandemic on the continent. These sequences have profoundly affected how public health officials in Africa have navigated the COVID-19 pandemic. RATIONALE We demonstrate how the first 100,000 SARS-CoV-2 sequences from Africa have helped monitor the epidemic on the continent, how genomic surveillance expanded over the course of the pandemic, and how we adapted our sequencing methods to deal with an evolving virus. Finally, we also examine how viral lineages have spread across the continent in a phylogeographic framework to gain insights into the underlying temporal and spatial transmission dynamics for several variants of concern (VOCs). RESULTS Our results indicate that the number of countries in Africa that can sequence the virus within their own borders is growing and that this is coupled with a shorter turnaround time from the time of sampling to sequence submission. Ongoing evolution necessitated the continual updating of primer sets, and, as a result, eight primer sets were designed in tandem with viral evolution and used to ensure effective sequencing of the virus. The pandemic unfolded through multiple waves of infection that were each driven by distinct genetic lineages, with B.1-like ancestral strains associated with the first pandemic wave of infections in 2020. Successive waves on the continent were fueled by different VOCs, with Alpha and Beta cocirculating in distinct spatial patterns during the second wave and Delta and Omicron affecting the whole continent during the third and fourth waves, respectively. Phylogeographic reconstruction points toward distinct differences in viral importation and exportation patterns associated with the Alpha, Beta, Delta, and Omicron variants and subvariants, when considering both Africa versus the rest of the world and viral dissemination within the continent. Our epidemiological and phylogenetic inferences therefore underscore the heterogeneous nature of the pandemic on the continent and highlight key insights and challenges, for instance, recognizing the limitations of low testing proportions. We also highlight the early warning capacity that genomic surveillance in Africa has had for the rest of the world with the detection of new lineages and variants, the most recent being the characterization of various Omicron subvariants. CONCLUSION Sustained investment for diagnostics and genomic surveillance in Africa is needed as the virus continues to evolve. This is important not only to help combat SARS-CoV-2 on the continent but also because it can be used as a platform to help address the many emerging and reemerging infectious disease threats in Africa. In particular, capacity building for local sequencing within countries or within the continent should be prioritized because this is generally associated with shorter turnaround times, providing the most benefit to local public health authorities tasked with pandemic response and mitigation and allowing for the fastest reaction to localized outbreaks. These investments are crucial for pandemic preparedness and response and will serve the health of the continent well into the 21st century

Immunological defects in septic shock. Deficiency of natural Killer cells and T-lymphocytes Defectos inmunológicos en el shock séptico. Deficiencia de células natural killer y de linfócitos T.

It is well known that an immunosuppressive response occurs after acute trauma. Some cellular mediators participate in the pathogenesis of septic shock. However, the exact role of the lymphocyte subsets and natural killer (NK) activity in this condition is not clear. We studied NK cytolytic activity through a 51Cr liberation assay using K-562 target cells in 20 patients with initial septic shock (10 men and 10 females, mean age 41 years old). Lymphocyte subsets CD3 (T3), CD4 (T4), CD8 (T8), CD16 (Leu-11) and CD56 (Leu-19) were also studied by indirect immunofluorescence. Compared to results obtained in 20 healthy volunteers, patient's NK activity was decreased (4.6 +/- 3.9 vs 26.1 +/- 10, p less than 0.025), CD16 was lower (10%/187 vs 15%/280 per ul) and CD56 was also lower (6%/120 vs 12%/224 per ul), p less than 0.05. T lymphocyte subsets were also decreased: CD3 cells (1100 vs 1352 per ul) and CD4 cells (634 vs 873 per ul), p less than 0.05. Thus, a severe decrease in NK cells and N
