Incidência e mortalidade por leucemia nos países do sul da europa em 2012

A incidência de leucemia é parcialmente explicada por exposição ambiental (Ferreira, Couto, Alves, Oliveira, & Koifman, 2012), mas a mortalidade reflete a qualidade e o acesso à terapêutica (Bertuccio et al., 2013). Comparar ocorrência de leucemia entre áreas geográficas permite levantar hipóteses sobre fatores que explicam heterogeneidade entre regiões. MÉTODOS Casos observados (incidentes e óbitos) e respetivas taxas (/100.000) para 2012 em cada um dos quatro países obtidos da IARC - International Agency for Research on Cancer (WHO, 2016). Casos esperados (incidentes e óbitos) obtidos através de taxas da população Europeia com estratificação por género e faixa etária (0-14; 15-39; 40-64 e 65 ou mais anos) Razão Padronizada de Mortalidade (RPM) e da Razão Padronizada de Incidência (RPI) para cada país e respetivo intervalo de confiança a 95% (IC95%) pelo teste exato de Fisher. Taxas apresentadas por 100.000 CONCLUSÃO De acordo com os resultados há variabilidade geográfica na incidência e mortalidade por leucemia. Diferenças na incidência por leucemia entre estes quatro países sugerem uma combinação diferenciada de fatores genéticos e ambientais de acordo com o país. Relativamente à variabilidade geográfica para a mortalidade, os resultados sugerem a necessidade de equacionar a qualidade dos serviços de saúde de cada país relativamente à capacidade de tratamento, competência clínica e equidade no acesso aos cuidados. Avaliar a variabilidade na incidência e na mortalidade por leucemia observada em 2012 em quatro países do sul da Europa culturalmente próximos: Espanha, Portugal, Grécia e Itáliainfo:eu-repo/semantics/publishedVersio

Alteração do comprimento do passo durante a transposição de obstáculos em tarefas de movimentação de cargas na construção civil

A Construção Civil tem sido o sector que regista maior incidência de acidentes fatais a nível mundial. Diversos estudos têm sido efectuados no sentido de compreender as causas que contribuem para a ocorrência de elevados índices de sinistralidade neste sector. Todavia, o contributo da movimentação manual de cargas, para a ocorrência de quedas na Construção Civil, tem sido descurado. No presente artigo procedeu-se, através de simulação laboratorial, ao estudo da influência da movimentação manual de cargas para a ocorrência de acidentes em operações envolvendo a transposição de obstáculos em obra. Verificou-se que o comprimento de passo e a passada do pé de avanço são alterados com o transporte de carga, aumentando a probabilidade de ocorrência de acidentes envolvendo quedas

Removal of diclofenac and sulfamethoxazole from aqueous solutions and wastewaters using a three-dimensional electrochemical process

The three-dimensional (3D) electrochemical treatment process was studied for the removal of two pharmaceuticals, diclofenac (anti-inflammatory) and sulfamethoxazole (antibiotic), in mono and bi-component systems. Adsorption and conventional two-dimensional electrochemical processes were initially studied and then combined to develop the 3D process. The influence of different operating parameters on the removal efficiency was studied: the distance between the cathode and the anode, the pharmaceutical and electrolyte (NaCl) concentrations, the pH, and the (carbon-based) adsorbent used as particulate electrode (biochar and commercial activated carbon, granulometry, and amount). The energy consumption and the electric energy per order were evaluated. The results demonstrate the efficiency of the 3D process for the removal of diclofenac and sulfamethoxazole from aqueous solutions, both for mono- and bi-component systems, achieving their complete removal respectively in 10 and 30 min, using a Mixed Metal Oxide anode (titanium-coated with RuO2-IrO2-TiO2), a stainless steel cathode, a biochar particulate electrode (1–2 mm), an initial pharmaceutical concentration of 10 mg/L, an inter-electrode distance of 7.5 cm, a pH value of 7 and a current density of 7 mA/cm2. The optimised 3D process was also successfully applied to a wastewater treatment plant effluent, but lower removal efficiencies were observed (after 30 min) for bi-component fortified samples; 49% for DCF and 86% for SMX, with energy consumptions of 1224 and 613 Wh/g and an electric energy per order of 19.1 and 8.77 kWh/m3 respectively. On the other hand, the pharmaceuticals were completely removed from the effluent when real concentrations (i.e. without their addition) were usedThis research was funded by the Associate Laboratory for Green Chemistry-LAQV, which is funded by Portuguese national funds through projects UIDB/50006/2020, UIDP/50006/20POCI-01–0247-FEDER-039882), sponsored by the Program “Portugal 2020″, and co-funded by “Fundo Europeu de Desenvolvimento Regional (FEDER)” through POCI.

Bradykinin-induced Ca2+ signaling in human subcutaneous fibroblasts involves ATP release via hemichannels leading to P2Y12 receptors activation

Chronic musculoskeletal pain involves connective tissue remodeling triggered by inflammatory mediators, such as bradykinin. Fibroblast cells signaling involve changes in intracellular Ca2+ ([Ca2+]i). ATP has been related to connective tissue mechanotransduction, remodeling and chronic inflammatory pain, via P2 purinoceptors activation. Here, we investigated the involvement of ATP in bradykinin-induced Ca2+ signals in human subcutaneous fibroblasts. Bradykinin, via B2 receptors, caused an abrupt rise in [Ca2+]i to a peak that declined to a plateau, which concentration remained constant until washout. The plateau phase was absent in Ca2+-free medium; [Ca2+]i signal was substantially reduced after depleting intracellular Ca2+ stores with thapsigargin. Extracellular ATP inactivation with apyrase decreased the [Ca2+]i plateau. Human subcutaneous fibroblasts respond to bradykinin by releasing ATP via connexin and pannexin hemichannels, since blockade of connexins, with 2- octanol or carbenoxolone, and pannexin-1, with 10Panx, attenuated bradykinin-induced [Ca2+]i plateau, whereas inhibitors of vesicular exocytosis, such as brefeldin A and bafilomycin A1, were inactive. The kinetics of extracellular ATP catabolism favors ADP accumulation in human fibroblast cultures. Inhibition of ectonucleotidase activity and, thus, ADP formation from released ATP with POM-1 or by Mg2+ removal from media reduced bradykinin-induced [Ca2+]i plateau. Selective blockade of the ADP-sensitive P2Y12 receptor with AR-C66096 attenuated bradykinin [Ca2+]i plateau, whereas the P2Y1 and P2Y13 receptor antagonists, respectively MRS 2179 and MRS 2211, were inactive. Human fibroblasts exhibited immunoreactivity against connexin-43, pannexin-1 and P2Y12 receptor. Bradykinin induces ATP release from human subcutaneous fibroblasts via connexin and pannexin-1-containing hemichannels leading to [Ca2+]i mobilization through the cooperation of B2 and P2Y12 receptors

Um estudo de coorte dinâmico prospetivo

Publisher Copyright: © 2021 Sociedade Portuguesa de Alergologia e Imunologia Clínica.Background: Since the last Portuguese National Asthma Survey (2010), important developments on the knowledge of asthma, its classification, and therapeutic options have occurred. Also, the evolution of information and communication technologies promotes the use of new data collection methodologies and the existence of digital tools simplifies longitudinal data collection, namely by the establishment of an online panel of participants. Objectives: The main objective of this project is the establishment of a national panel of patients with asthma for the surveillance of variations on disease control in the next 10 years (2020-2030). With that purpose, we aim to develop and implement an online platform for the collection of data related to asthma in Portugal and to carry out an initial study to estimate the variation, between 2010 and 2021, of the proportion of patients with uncontrolled asthma in Portugal. Methods: This is an ongoing observational study based on the establishment of an open cohort of patients with asthma, using an online platform that will include an initial questionnaire and, in a second step, complementary questions for further characterization. The study population consists of adolescents (>14 years old) and adults with current asthma (previous diagnosis of asthma, or two or more positive answers to validated screening questionnaire, or who are currently taking asthma medication), living in Portugal. Asthma control will be based on the Control of Allergic Rhinitis and Asthma Test (CARAT) and defined by a total score > 24 or the lower airways score ≥ 16. Expected results: With this project, an open cohort of patients with asthma will be obtained through an online questionnaire. Also, the implementation of an online platform for an ongoing collection of data on asthma will gather up-to-date and robust information based on ‘real world’ data, collected using an easy-to-use, high-reach methodology. The data obtained in the initial study will improve the knowledge of the determinants of disease management and its impact on the use of health resources. Conclusion: The estab-lishment of an online panel of patients with asthma that, together with an online tool to support observational studies have the poten-tial to generate knowledge on the evolution of asthma management at the national level. This project will therefore contribute to inform health policies and improve the clinical outcomes of patients with asthma in Portugal.publishersversionpublishe

Effects of in vitro digestion and in vitro colonic fermentation on stability and functional properties of yerba mate (Ilex paraguariensis A. St. Hil.) beverages

Yerba mate (Ilex paraguariensis) is a plant that grows naturally in South America. From its leaves and thin stems different kinds of beverages are prepared (chimarrão, tererê and tea mate), all of them rich in bioactive substances. The aim of this study was to evaluate the influence of in vitro gastrointestinal digestion and colonic fermentation on the stability of the polyphenols and on the antioxidant, antimicrobial and antitumoral activities of the yerba mate beverages. The phenolic chromatographic profile revealed that both the in vitro digestion and the colonic fermentation caused a pronounced decrease in 3,5-O-dicaffeoylquinic acid and 5-O-caffeoylquinic acid in the preparations. However, 3-O-caffeoylquinic acid, 4-O-caffeoylquinic acid and salvianolic acid I were only barely affected in all preparations. Despite the decrease in the phytochemicals content, yerba mate beverages maintain their functional properties such as antioxidant, antibacterial and antitumoral activities.The authors thank the Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq, Proc. 3079/2015-8) and Fundação Araucária (Proc.24/2012) for funding this study.
