    O artigo apresenta a distribuição espacial de alguns potenciais de impactos das emissões de monóxido de carbono (CO), metano (CH4), óxidos de nitrogênio (NOx) e óxido nitroso (N2O) causadas pela queimada de cana-de-açúcar no Brasil utilizando o SIG ArcGIS. As categorias de potenciais de impactos ambientais avaliados são: aquecimento global, formação de ozônio troposférico, acidificação e toxicidade humana

    OBJECTIVES: The 5-item Compliance Questionnaire for Rheumatology (CQR5) proved reliability and validity in respect of identification of patients likely to be high adherers (HAs) to anti-rheumatic treatment, or low adherers (LAs), i.e. taking<80% of their medications correctly. The objective of the study was to validate an Italian version of CQR5 (I-CQR5) in rheumatoid arthritis (RA) patients and to investigate factors associated with high adherence. METHODS: RA patients, undergoing treatment with ≥1 self-administered conventional synthetic disease-modifying anti-rheumatic drug (csDMARD) or biological DMARD (bDMARD), were enrolled. The cross-cultural adaptation and validation of I-CQR5 followed standardised guidelines. I-CQR5 was completed by patients on one occasion. Data were subjected to factor analysis and Partial Credit model Parametrisation (PCM) to assess construct validity of I-CQR5. Analysis of factors associated with high adherence included demographic, social, clinical and treatment information. Factors achieving a p<0.10 in univariate analysis were included in multivariable analysis. RESULTS: Among 604 RA patients, 274 patients were included in the validation and 328 in the analysis of factors associated with adherence. Factor analysis and PCM confirmed the construct validity and consistency of I-CQR5. HAs were found to be 109 (35.2%) of the patients. bDMARD treatment and employment were found to be independently associated with high adherence: OR 2.88 (1.36-6.1), p=0.006 and OR 2.36 (1.21-4.62), p=0.012, respectively. CONCLUSIONS: Only one-third of RA patients were HAs according to I-CQR5. bDMARDs and employment status increased by almost 3-fold the likelihood of being highly adherent to the anti-rheumatic treatment.Peer reviewe

    O objetivo desta pesquisa foi avaliar o efeito da irrigação com água, efluente secundário de nitrogenada na produção vegetal, na quantidade de liteira depositada e nos conteúdos de matéria orgânica particulada em uma pastagem de capim-Bermuda tifton 85. O delineamento experimental foi composto de quatro blocos ao acaso e seis tratamentos: SI (controle, sem fertilização e sem irrigação); W100, irrigação com água e 100% da dose de fertilizante nitrogenado recomendado; E0, E33, E66 e E100, irrigado com esgoto tratado e adição de 0, 33; 66 e 100% da dose recomendada, respectivamente. Amostras de efluente/água, solo, produção vegetal e liteira foram coletadas no período de abril a outubro de 2007. A maior oferta de N nos tratamentos E66, E100 e A100, através da fertilização, irrigação e ciclagem interna pela Bermuda Tifton 85 em período pós chuvas (abril?junho de 2007). No sistema avaliado, a deposição de liteira foi mais diferentes tratamentos. Maiores conteúdos médios de MOP foram observados no solo dos tratamentos irrigados e fertilizados.1 CD-ROM

    TNFα blockers and infectious risk in rheumatoid arthritis

    Get PDF
    Patients suffering from rheumatoid arthritis have increased risk of infections when compared with general population. The risk depends directly from disease activity and severity. Furthermore, risk increases with aging, immunosuppressive agents and comorbidities such as diabetes, pulmonary and cardiac diseases. In particular corticosteroids, even at low doses, are a major risk factor. Due to disease related risk it is difficult to separate the risk deriving from the use of TNF alpha blockers. Data from clinical trials, meta-analysis and national registers are somewhat contradictory. In patients with rheumatoid arthritis on routine follow-up, treatment with TNF alpha blockers seems to carry an increased risk of infections compared to traditional DMARDs but not associated with increased risk of overall serious infection. Physicians should carefully monitor for signs of infection when using TNF alpha blockers, particularly shortly after treatment initiation

    Climate change-related risks and adaptation potential in Central and South America during the 21st century

    Climate-related risks in Central and South America have received increased attention and concern in science and policy, but an up-to-date comprehensive review and synthesis of risks and adaptation potential is currently missing. For this paper we evaluated over 200 peer-reviewed articles and grey literature documents published since 2012. We found that climate change in Central and South America during the 21st century may increase the risk to severe levels for the following topical risk clusters: (a) Food insecurity; (b) Floods and landslides; (c) Water scarcity; (d) Epidemics of vector-borne diseases; (e) Amazon Forest biome shift; (f). Coral bleaching; (g) Coastal risks of sea level rise, storm surges and erosion; (h) Systemic failure due to cascading impacts of hazards and epidemics. Our synthesis also identified feasible adaptation measures for each risk. The impacts of the risks will be heterogeneous throughout the region, with rural communities, Indigenous peoples, Afro-Latin Americans, women, disabled people, and migrants identified as being the most severely affected. We refer to a number of adaptation options for each risk. However, unabated climate change together with low adaptive capacity will strictly limit adaptation options. Immediate strengthening of policies for building adaptive capacity and increase of research on the risk-adaptation nexus in Central and South America are paramount. Our findings might contribute to guide the adjustment and emphasis of adaptation policies and climate risk management strategies from local to national level
