DESENVOLVIMENTO E SUSTENTABILIDADE SOCIOAMBIENTAL NO CAMPO, NA CIDADE E NA FLORESTA: UMA INTERVENÇÃO EDUCATIVA

Como uma condição fundamental ao desenvolvimento individual e coletivo do ser humano, a saúde é interdependente das complexas relações da práxis do viver em sociedade, que comporta dimensões bio-psico-eco-social historicamente determinadas e mediadas pela linguagem, pela cultura, pela política, pela técnica, pelos processos econômicos e da produção. Ampliar o conceito de ambiente e compreender que este é socialmente determinado é uma necessidade para a abordagem complexa do processo saúde – doença – cuidado. Assim, o ambiente deixa de ser apenas uma dimensão externa ao homem, passando para uma condição de interdependência e interdefinibilidade das demais dimensões da vida do ser humano. Visando conscientizar e mobilizar a sociedade sobre a relação do meio ambiente e saúde, esse trabalho objetivou desenvolver uma ação educativa com alunos do 2° ano do ensino médio do curso técnico em enfermagem.(http://dx.doi.org/10.14295/cad.cult.cienc.v13i2.862

Evaluation of the antinociceptive and anti-inflammatory effects of the acetone extract from Anacardium occidentale L

The stem bark of Anacardium occidentale L. (Anacardiaceae), commonly called cashew, is used in Brazilian traditional medicine for the treatment of gastric and inflammatory disorders. The present study was carried out to investigate the in vivo anti-inflammatory activities of the acetone extract (AE) of the stem bark of A. occidentale. We evaluated the pharmacological activities of this plant material through the analgesic, antiedematogenic and chemotaxic inhibitory effects produced by the AE. The oral administration (p.o.) of mice with the AE (0.1, 0.3 and 1.0 g/kg) or positive control indomethacin (10 mg/kg) inhibited acetic acid-induced writhing by 18.9, 35.9, 62.9 and 68.9%, respectively (ID50% = 530 mg/kg). The highest dose of the AE was able to inhibit croton oil-induced ear edema formation by 56.8% (indomethacin at 10 mg/kg, p.o. - 57.6% inhibition). When submitted to the carrageenan-induced peritonitis test, the AE (0.1, 0.3 and 1.0 g/kg, p.o.) impaired leukocyte migration into the peritoneal cavity by 24.8, 40.5 and 49.6%, respectively. The positive control, dexamethasone (2 mg/kg, s.c.), inhibited leukocyte migration by 66.9%. These results indicate the presence of anti-inflammatory and antinociceptive principles in the acetone extract of Anacardium occidentale, and reinforce the plant's potential therapeutic use against pain and inflammatory diseases.As cascas do caule do Anacardium occidentale L. (Anacardiaceae), conhecido como cajueiro, são popularmente utilizadas no Brasil para o tratamento de doenças gástricas e inflamatórias. Este estudo teve como objetivo a avaliação farmacológica in vivo da atividade antiinflamatória do extrato acetônico (AE) obtido das cascas do A. occidentale, investigando os efeitos analgésico, antiedematogênico e inibitório sobre a quimiotaxia deste material botânico. A administração oral (p.o.) em camundongos com o AE (0,1; 0,3 e 1 g/kg) ou o controle positivo indometacina (10 mg/kg) inibiu as contorções abdominais induzidas pelo ácido acético em 18,9; 35,9; 62,9 e 68,9% respectivamente (ID50% = 530 mg/kg). Esta maior dose do AE também inibiu o edema de orelha produzido pelo óleo de cróton em 56,8% (indometacina, 10 mg/kg, p.o. - 57,6% de inibição). No teste da peritonite induzido pela carragenina, o AE (0,1; 0,3; e 1,0 mg/kg, p.o.) reduziu a migração de leucócitos para a cavidade peritoneal em 24,8; 40,5; e 49,6% respectivamente, enquanto que o controle positivo dexametasona (2 mg/kg, s.c.) inibiu a migração de leucócitos em 66,9%. Estes resultados indicam a presença de princípios ativos antiinflamatórios e antinociceptivos no extrato acetônico de Anacardium occidentale e reforçam o potencial terapêutico da planta em doenças que envolvem dor e inflamação

Effects of hospital facilities on patient outcomes after cancer surgery: an international, prospective, observational study

Background Early death after cancer surgery is higher in low-income and middle-income countries (LMICs) compared with in high-income countries, yet the impact of facility characteristics on early postoperative outcomes is unknown. The aim of this study was to examine the association between hospital infrastructure, resource availability, and processes on early outcomes after cancer surgery worldwide.Methods A multimethods analysis was performed as part of the GlobalSurg 3 study-a multicentre, international, prospective cohort study of patients who had surgery for breast, colorectal, or gastric cancer. The primary outcomes were 30-day mortality and 30-day major complication rates. Potentially beneficial hospital facilities were identified by variable selection to select those associated with 30-day mortality. Adjusted outcomes were determined using generalised estimating equations to account for patient characteristics and country-income group, with population stratification by hospital.Findings Between April 1, 2018, and April 23, 2019, facility-level data were collected for 9685 patients across 238 hospitals in 66 countries (91 hospitals in 20 high-income countries; 57 hospitals in 19 upper-middle-income countries; and 90 hospitals in 27 low-income to lower-middle-income countries). The availability of five hospital facilities was inversely associated with mortality: ultrasound, CT scanner, critical care unit, opioid analgesia, and oncologist. After adjustment for case-mix and country income group, hospitals with three or fewer of these facilities (62 hospitals, 1294 patients) had higher mortality compared with those with four or five (adjusted odds ratio [OR] 3.85 [95% CI 2.58-5.75]; p<0.0001), with excess mortality predominantly explained by a limited capacity to rescue following the development of major complications (63.0% vs 82.7%; OR 0.35 [0.23-0.53]; p<0.0001). Across LMICs, improvements in hospital facilities would prevent one to three deaths for every 100 patients undergoing surgery for cancer.Interpretation Hospitals with higher levels of infrastructure and resources have better outcomes after cancer surgery, independent of country income. Without urgent strengthening of hospital infrastructure and resources, the reductions in cancer-associated mortality associated with improved access will not be realised

Qualidade e atributos físicos de um Latossolo Vermelho Distroférrico típico em diferentes sistemas de manejo

O objetivo deste estudo foi avaliar os atributos físicos e a qualidade de um Latossolo Vermelho Distroférrico típico em diferentes sistemas de uso: cana-de-açúcar, pastagem extensiva e mata nativa. O estudo foi realizado em Rio Branco, região sudoeste de Mato Grosso. Em cada ambiente amostrou-se as camadas de solo de 0 a 0,1; 0,1 a 0,2 e 0,2 a 0,3 m de profundidade. Foram avaliadas as características de densidade do solo, resistência mecânica do solo à penetração, porosidade total, além de micro e macroporosidade. De acordo com os resultados obtidos, foi organizado um diagrama comparativo de qualidade do solo e calculado o índice de qualidade de solo. A pastagem apresentou altos valores de resistência mecânica do solo à penetração e maior média de densidade do solo, comparado aos demais sistemas de usos. A cana-de-açúcar e a pastagem sofreram reduções drásticas de qualidade física do solo em relação à mata nativa nas camadas de 0 a 0,1 e 0,1 a 0,2 m do solo. A camada de 0,2 a 0,3 m foi a que sofreu menor impacto na qualidade do solo mediante os diferentes sistemas de uso
