Purposes. The optimal treatment of N2 non-small cell lung cancer (NSCLC) in older patients is still debate and represent an important treatment and ethical problem. Patients and methods. Between January 2000 to December 2010, 273 older patients underwent lung resection for (NSCLC). Results. The overall-operative mortality was 9.5%. Risk factors for in-hospital mortality were pneumonectomy and poli-vasculopathy. One, 3 and 5-year survival were 73%, 23% and 16% respectively. Conclusions. In potentially operable older patients with NSCLC we need to make every effort to exclude N2 involvement because very poor long-term survival. Pneumonectomy in older patients gains prohibitive in-hospital mortality.

Importance A key factor in assessing the effectiveness and cost-effectiveness of antiretroviral therapy (ART) as a prevention strategy is the absolute risk of HIV transmission through condomless sex with suppressed HIV-1 RNA viral load for both anal and vaginal sex. Objective To evaluate the rate of within-couple HIV transmission (heterosexual and men who have sex with men [MSM]) during periods of sex without condoms and when the HIV-positive partner had HIV-1 RNA load less than 200 copies/mL. Design, Setting, and Participants The prospective, observational PARTNER (Partners of People on ART-A New Evaluation of the Risks) study was conducted at 75 clinical sites in 14 European countries and enrolled 1166 HIV serodifferent couples (HIV-positive partner taking suppressive ART) who reported condomless sex (September 2010 to May 2014). Eligibility criteria for inclusion of couple-years of follow-up were condomless sex and HIV-1 RNA load less than 200 copies/mL. Anonymized phylogenetic analysis compared couples' HIV-1 polymerase and envelope sequences if an HIV-negative partner became infected to determine phylogenetically linked transmissions. Exposures Condomless sexual activity with an HIV-positive partner taking virally suppressive ART. Main Outcomes and Measures Risk of within-couple HIV transmission to the HIV-negative partner. Results Among 1166 enrolled couples, 888 (mean age, 42 years [IQR, 35-48]; 548 heterosexual [61.7%] and 340 MSM [38.3%]) provided 1238 eligible couple-years of follow-up (median follow-up, 1.3 years [IQR, 0.8-2.0]). At baseline, couples reported condomless sex for a median of 2 years (IQR, 0.5-6.3). Condomless sex with other partners was reported by 108 HIV-negative MSM (33%) and 21 heterosexuals (4%). During follow-up, couples reported condomless sex a median of 37 times per year (IQR, 15-71), with MSM couples reporting approximately 22 000 condomless sex acts and heterosexuals approximately 36 000. Although 11 HIV-negative partners became HIV-positive (10 MSM; 1 heterosexual; 8 reported condomless sex with other partners), no phylogenetically linked transmissions occurred over eligible couple-years of follow-up, giving a rate of within-couple HIV transmission of zero, with an upper 95% confidence limit of 0.30/100 couple-years of follow-up. The upper 95% confidence limit for condomless anal sex was 0.71 per 100 couple-years of follow-up. Conclusions and Relevance Among serodifferent heterosexual and MSM couples in which the HIV-positive partner was using suppressive ART and who reported condomless sex, during median follow-up of 1.3 years per couple, there were no documented cases of within-couple HIV transmission (upper 95% confidence limit, 0.30/100 couple-years of follow-up). Additional longer-term follow-up is necessary to provide more precise estimates of risk.

A escala é um elemento relevante para trabalhos de pesquisa, mas freqüentemente temos dificuldades de traçar um limiar escalar para o nosso objeto de estudo, ou seja, nos deparamos com problemas de colocar a realidade observada em seu conjunto dentro de um recorte que possa representá-la. Por esta razão, o presente artigo expõe algumas abordagens escalares e multiescalares da atividade social, suscitando o problema da poliformia do espaço e a reflexão acerca da adequação permanente da nossa estrutura conceitual às possibilidades heurísticas de todas as escalas. Para resgatar a discussão sobre escalas, utilizaram-se como referenciais teóricos como Castro, Lobato Corrêa, Vainer, Smith, Santos, Macêdo entre outros, os quais apresentam variações e divergências acerca do termo. Com o intuito de analisar a definição e o uso de escala como conceito, este artigo tem como objetivo elucidar a melhor aplicabilidade sobre o tema para os estudantes da área de geografia.

Este trabalho apresenta a ação hegemônica, desde a década de 1950, que a pecuária bovina de corte exerce nas áreas rurais do oeste paulista (SP). Enquanto uma totalidade parcial do espaço geográfico em que atua o setor, a região se transformou em um referencial nacional na tomada de preços dos bovinos em peso de abate. No atual processo de deslocamento da boiada nacional do Centro-Sul para o Norte do país, neste trabalho se retrata a participação dos agropecuaristas regionais nesse desenrolar. Mesmo com a diminuição do percentual da boiada nacional presente nas áreas agrícolas da região, dos escritórios localizados nos edifícios agropecuários de Araçatuba, Presidente Prudente e Ribeirão Preto, a elite ruralista dá o encaminhamento de suas possessões na longínqua frente de expansão da atividade em terras setentrionais do Brasil.

The atmospheric corrosion of modern and historic alloys used in cultural heritage has been investigated by applying specific accelerated ageing methods. Three main research lines were carried out, involving different materials. In the first part, the atmospheric corrosion of a modern Cu-3Si-1Mn bronze was investigated through accelerated ageing tests simulating outdoor runoff conditions. The corrosion processes were evaluated through different analyses, and the results obtained were compared to those of a traditional quaternary bronze. The second line was carried out to characterise historic aluminium alloys used in aeronautics to develop and apply innovative protection strategies for their conservation. Historic wrecks were identified and characterised through micro and macroscale observations. Moreover, accelerated ageing tests were performed on both historic and modern alloys to compare their behaviour and select the best modern substrate to be used for the development of effective coatings. The third research line aimed to develop accelerate sampling and ageing methods to investigate the role of particulate matter (PM) in the atmospheric corrosion of bronzes and metals in general. The first approach consisted in the fine-tuning of an efficient accelerated method for ambient PM sampling on bronze specimens followed by their accelerated ageing, in order to establish a correlation between the PM and the substrate’s corrosion. After the accelerated ageing of the specimens, the corrosion was evaluated by surface characterisation and correlated to the PM features. The second approach consisted in the development of a synthetic PM formulation and of an artificial deposition method, which was performed by spraying mixtures containing the main PM inorganic fractions on a G-85 bronze with an airbrush. The deposition efficiency was assessed, and the effect of synthetic PM on the bronze corrosion was evaluated. The results were compared to those obtained by ambient PM deposition.

Global population growth reflects how humans increasingly exploited Earth's resources. Urbanization develops along with anthropization. It is estimated that nearly 60% of the world's population lives in urban areas, which symbolize the denaturalized dimension of current modernity. Cities are artificial ecosystems that suffer most from environmental issues and climate change. The Urban Heat Island (UHI) effect is a common microclimatic phenomenon affecting cities, which causes considerable differences between urban and rural areas temperatures. Among the driving factors, the lack of vegetation in urban settlements can damage both humans and the environment (health diseases, heat waves caused deaths, biodiversity loss, and so on). As the world continues to urbanize, sustainable development increasingly depends on successful management of urban areas. To enhance cities’ resilience, Nature-based Solutions (NbSs), are defined as an umbrella concept that encompasses a wide range of ecosystem-based approaches and actions to climate change adaptation (CCA) and disaster risk reduction (DRR). This paper analyzes a 15-days study on air temperature trends carried out in Isla, a small locality in the Maltese archipelago, and proposes Nature-based Solutions-characterized scenarios to mitigate the Urban Heat Island effect the Mediterranean city is affected by. The results demonstrates how in some areas where vegetation is present, lower temperatures are recorded than in areas where vegetation is absent or scarce. It also appeared that in one location, the specific type of vegetation does not contribute to high temperature mitigation, whereas in another one, different environmental parameters can influence the measurements. Among the case-specific Nature-based Solutions proposed there are vertical greening (green wall, façades, ground based greening, etc.), tree lines, green canopy, and green roofs.

O Modelo de Atenção em Saúde representa uma referência para se pensar na assistência à saúde de determinado local, organizando os elementos do processo de trabalho em saúde de forma a intervir de maneira resolutiva nos problemas. O Modelo Assistencial vai sendo modificado e construído no cotidiano das relações políticas entre seus elementos. Diante da necessidade de se ter um modelo de atenção resolutivo, torna-se necessário o emprego de estudos epidemiológicos. Estes estudos são úteis na avaliação dos serviços públicos de saúde uma vez que identificam as necessidades não atendidas e ajudam na identificação de problemas gerenciais. Este trabalho teve por objetivo avaliar a condição de saúde bucal dos usuários da Estratégia saúde da Família (ESF) no município de Passa Tempo - MG, como forma de subsidiar uma futura reorientação do modelo de atenção em saúde bucal. Para tal foi realizada uma descrição da condição de saúde bucal em relação à cárie dentária nas idades de 5 anos, 12 anos, 18 anos e nos grupos etários de 35-44 anos, 65-74 anos. Os resultados deste estudo foram comparados com os resultados obtidos no levantamento epidemiológico SB Brasil 2003 (MS) e com as metas da Organização Mundial de Saúde (OMS). A partir disso, foi apontada a importância dos diagnósticos das condições bucais para uma reorientação do modelo de atenção em saúde bucal vigente no município.
