Dengue: aspectos epidemiológicos no município de Salgueiro do Sertão Pernambucano, Brasil / Dengue: epidemiological aspects in the municipality of Salgueiro do Sertão Pernambucano, Brazil
A dengue é atualmente a arbovirose mais prevalente no Brasil, configurando-se como um agravo na saúde pública nas últimas décadas. O presente trabalho tem como objetivo analisar estatisticamente dados cadastrados em planilhas eletrônicas do SINAN. Foi realizado um estudo de série histórica observacional do tipo transversal dos casos notificados de dengue no município de Salgueiro- PE, Brasil, entre os anos de 2007 a 2012. O Sinan online notificou para o intervalo de tempo em estudo, 1818 casos de dengue, desses 62,65% eram do sexo feminino e 37,35% do sexo masculino. Os dados demonstram que houve uma quantidade significativa de casos para região, porém a questão da subnotificação é notável, além disso, cabe aos órgãos de saúde pública do município, melhorar a qualidade de prevenção desse agravo
Acidentes ofídicos: perfil epidemiológico na mesorregião do sertão Pernambucano, Brasil / Snaky accidents: epidemiological profile in the meso-region of Pernambuco, Brazil
Os acidentes ofídicos representam sério problema de saúde pública, pela freqüência e morbi-mortalidade, o Brasil tem cerca de 20.000 casos por ano, o coeficiente médio, foi de 13,8 casos/100 mil habitantes. O objetivo do estudo foi analisar os casos notificados de acidentes ofidicos ocorridos na região do Sertão do Pajeú, Pernambuco, Brasil, entre os anos de 2007 a 2016. ). Os dados foram tabulados em um banco de dados com auxílio do recurso Tabelas e Gráficos do Excel 2010. No período investigado o número de casos de acidentes ofídicos foram 1.375 casos, o município que teve a maior prevalência foi Serra Talhada. Percebe-se que o perfil desse estudo corrobora com perfil do Brasil, onde se tem destaque para sexo masculino
Doença de chagas: tendência epidemiológica por regiões do Brasil / Chagas disease: epidemiological trend by regions of Brazil
A doença de Chagas é uma condição crônica negligenciada com elevada carga de morbimortalidade, no período de 2000 a 2013 foram notificados 1.570 casos de doença de Chagas aguda . Trata-se de um estudo transversal de caráter descritivo, teve como população os casos de notificados doença de chagas aguda dos últimos anos disponíveis do DATASUS,foram dos anos 2013 a 2014 no Brasil. Os dados obtidos foram coletados do DATASUS nas informações de saúde (TABNET). O total de 191 de notificações de doença de chagas aguda no anos de 2014 no Brasil. Os dados epidemiológicos demonstram a necessidade de se aumentar à vigilância na região Norte e incorporar indicadores ambientais para a detecção precoce e prevenção de agravos à saúde da população em relação a doença de chagas
Ability of two new thiazolidinediones to downregulate proinflammatory cytokines in peripheral blood mononuclear cells from children with asthma
Allergic asthma is a chronic, complex inflammatory disease of the airway. Despite extensive studies on the immunomodulation of T helper (Th) cell pathways (i.e., Th1 and Th2) in asthma, little is known about the effects of Th17 pathway modulation, particularly that involving peroxisome proliferator-activated receptors (PPARs). In response, two new thiazolidinedione derivatives-namely, LPSF-GQ-147 and LPSF-CR-35 were synthesized and evaluated for their immunomodulatory effects on Th17-related cytokines, including interferon γ (IFNγ), interleukin IL-6, IL-17, and IL-22 in the peripheral blood mononuclear cells of asthmatic children. Both compounds were nontoxic even at high concentrations (i.e., 100 µM). The LPSF-CR-35 compound significantly reduced the levels of IL-17A (p = .039) and IFNγ (p = .032) at 10 µM. For IL-22 and IL-6, significant reduction occurred at 100 µM (p = .039 and p = .02, respectively). Conversely, LPSF-GQ-147 did not significantly inhibit the production of the tested cytokines, the levels of all of which were more efficiently reduced by LPSF-CR-35 than methylprednisolone, the standard compound. Real-time polymerase chain reaction assay confirmed that LPSF-GQ-147 has significant PPARγ modulatory activity. Such data indicate that both LPSF-CR-35 and LPSF-GQ-147 are promising candidates as drugs for treating inflammation and asthma
Synthesis of a Novel Thiazolidinedione and Evaluation of Its Modulatory Effect on IFN-γ, IL-6, IL-17A, and IL-22 Production in PBMCs from Rheumatoid Arthritis Patients
Rheumatoid arthritis (RA) is an autoimmune disease frequently characterized by chronic synovitis of multiple joints. The pathogenesis of RA is complex and involves many proinflammatory cytokines as Th17 related ones. PPARγ is a nuclear receptor activator that represses proinflammatory gene expression. Thus, this work aimed to synthetize a new thiazolidinedione (TZD) analogue based on a well-known anti-inflammatory and PPARγ agonist activity of this ring and evaluate its anti-inflammatory activity. After chemical structure confirmation, the compound named 5-(5-bromo-2-methoxy-benzylidene)-3-(2-nitro-benzyl)-thiazolidine-2,4-dione TM17 was submitted to cytokine releasing inhibition and PPARγ genetic modulation assays. The new compound showed no toxicity on human and murine cells, decreasing IL-6 secretion by murine splenocytes and reducing IL-17A, IL-22, and IFN-γ expression in peripheral blood mononuclear cells from patients with RA. TM17 was more efficient in modulating the mRNA expression of PPARγ than its well-used TZD agonist rosiglitazone. Surprisingly, TM17 was efficient on IL-17A and IFN-γ reduction, like the positive control methylprednisolone, and presented a better effect on IL-22 levels. In conclusion, PBMCs obtained from RA patients under TM17 treatment present a significant reduction in IL-17A, IL-22, and IFN-γ levels, but not IL-6 when compared with nontreated cells, as well as increase PPARγ mRNA expression in absence of stimulus addressing it as a promising molecule in RA treatment
NEOTROPICAL CARNIVORES: a data set on carnivore distribution in the Neotropics
Mammalian carnivores are considered a key group in maintaining ecological health and can indicate potential ecological integrity in landscapes where they occur. Carnivores also hold high conservation value and their habitat requirements can guide management and conservation plans. The order Carnivora has 84 species from 8 families in the Neotropical region: Canidae; Felidae; Mephitidae; Mustelidae; Otariidae; Phocidae; Procyonidae; and Ursidae. Herein, we include published and unpublished data on native terrestrial Neotropical carnivores (Canidae; Felidae; Mephitidae; Mustelidae; Procyonidae; and Ursidae). NEOTROPICAL CARNIVORES is a publicly available data set that includes 99,605 data entries from 35,511 unique georeferenced coordinates. Detection/non-detection and quantitative data were obtained from 1818 to 2018 by researchers, governmental agencies, non-governmental organizations, and private consultants. Data were collected using several methods including camera trapping, museum collections, roadkill, line transect, and opportunistic records. Literature (peer-reviewed and grey literature) from Portuguese, Spanish and English were incorporated in this compilation. Most of the data set consists of detection data entries (n = 79,343; 79.7%) but also includes non-detection data (n = 20,262; 20.3%). Of those, 43.3% also include count data (n = 43,151). The information available in NEOTROPICAL CARNIVORES will contribute to macroecological, ecological, and conservation questions in multiple spatio-temporal perspectives. As carnivores play key roles in trophic interactions, a better understanding of their distribution and habitat requirements are essential to establish conservation management plans and safeguard the future ecological health of Neotropical ecosystems. Our data paper, combined with other large-scale data sets, has great potential to clarify species distribution and related ecological processes within the Neotropics. There are no copyright restrictions and no restriction for using data from this data paper, as long as the data paper is cited as the source of the information used. We also request that users inform us of how they intend to use the data
