    BACKGROUND: As global initiatives increase patient access to surgical treatments, there remains a need to understand the adverse effects of surgery and define appropriate levels of perioperative care. METHODS: We designed a prospective international 7-day cohort study of outcomes following elective adult inpatient surgery in 27 countries. The primary outcome was in-hospital complications. Secondary outcomes were death following a complication (failure to rescue) and death in hospital. Process measures were admission to critical care immediately after surgery or to treat a complication and duration of hospital stay. A single definition of critical care was used for all countries. RESULTS: A total of 474 hospitals in 19 high-, 7 middle- and 1 low-income country were included in the primary analysis. Data included 44 814 patients with a median hospital stay of 4 (range 2-7) days. A total of 7508 patients (16.8%) developed one or more postoperative complication and 207 died (0.5%). The overall mortality among patients who developed complications was 2.8%. Mortality following complications ranged from 2.4% for pulmonary embolism to 43.9% for cardiac arrest. A total of 4360 (9.7%) patients were admitted to a critical care unit as routine immediately after surgery, of whom 2198 (50.4%) developed a complication, with 105 (2.4%) deaths. A total of 1233 patients (16.4%) were admitted to a critical care unit to treat complications, with 119 (9.7%) deaths. Despite lower baseline risk, outcomes were similar in low- and middle-income compared with high-income countries. CONCLUSIONS: Poor patient outcomes are common after inpatient surgery. Global initiatives to increase access to surgical treatments should also address the need for safe perioperative care. STUDY REGISTRATION: ISRCTN5181700

    Este estudo teve como objetivos elaborar um mapa de uso da terra com base nas imagens do satélite IKONOS II, delimitar de maneira automática as áreas de preservação permanente e identificar a ocorrência de conflitos de usos, tendo como referência legal o Código florestal e a Resolução n.º 303 do CONAMA. A pesquisa foi desenvolvida na entorno do Parque Nacional do Caparaó, pertencente aos municípios de Alto Jequitibá, Alto Caparaó, Caparaó e Espera Feliz, todos situados no estado de Minas Gerais. Utilizando os recursos disponíveis no geoprocessamento, foi possível mapear 8 classes de uso da terra e delimitar as áreas de preservação permanente situadas em áreas com altitudes superior a 1.800 metros (8,42 ha), no terço superior dos morros (18,67 ha); encostas com declividade superior a 45 graus (92,96 ha); nascentes e suas respectivas áreas de contribuição (1.989,44 ha); margens dos cursos d´água com largura inferior a 10 metros (3.957,19 ha); e no terço superior das sub-bacias (6.031,54 ha), perfazendo um total de 12.098,22 ha (48,06%) da área total da bacia. A área de uso indevido correspondeu a 8.922,91 ha (73,75%), sendo as classes cafezal (5.183,43 ha) e pastagem (3.650,74 ha) as principais ocorrências nessas áreas. Apenas 2.160,69 ha (18,40%) das áreas de preservação permanente estão protegidas por vegetação nativa.<br>The objective of this work was to prepare a map of land use based on the IKONOS II sattelite images, to automatically determine the permanent preservation areas and to identify the occurrence of use conflicts, using as legal reference the Forest Code and the nº 303 Resolution of the CONAMA. The research was developed around the Caparaó National Park, in lands of the municipalities of Alto Jequitibá, Alto Caparaó, Caparaó and Espera Feliz, all of them located in the State of Minas Gerais. Using the resources available in the geographic processing, it was possible to map 8 classes of land use and to delimitate the permanent preservation areas located in regions above 1,800 meters of altitude (8.42 ha), the third upper part the hills (18.67 ha); an hillsides with slopes above 45 degrees (92.96 ha); water course margins with width below 10 meters (3,957.19 ha); and the upper third part the sub basins totalizing 12,098.22 ha (48.06%) of the basin total area. The area of improper use corresponds to 8,922.91 ha (45.49 %), being the classes coffee crop (5,183.43 ha) and clear pasture (3,650.74 ha) the main occurrences in these areas. Only 2,160.69 ha (18.40 %) of the permanent preservation areas are protected by natural vegetation

    Análises técnica e econômica foram realizadas em imagens dos sensores IKONOS, TM/Landsat 5, ETM+/Landsat 7 e CCD/CBERS, objetivando a verificação da viabilidade destas como base de dados em projetos de reforma agrária. Essas análises efetuadas e a situação de mercado indicaram que a imagem IKONOS apresenta excelente desempenho técnico, mas o custo de aquisição inviabiliza sua utilização como base de dados para a reforma agrária. A imagem do Landsat 7, com baixo custo de aquisição, apresentou grande viabilidade técnica para fins de reforma agrária. No entanto, a perda do contato com a plataforma Landsat 7 inviabilizou a compra de novas imagens do sensor ETM+. A imagem CCD/CBERS apresentou a segunda maior similaridade com a verdade de campo e o menor índice Kappa para a classificação. Apesar do baixo índice de exatidão para a classificação, as análises de custo, o lançamento do CBERS-2 e a possibilidade de correção dos problemas de radiometria podem tornar as imagens da plataforma CBERS-2 concorrentes de peso no mercado e, ainda, preencher a lacuna deixada pela perda do Landsat 7. A imagem do Landsat 5 apresentou o mais baixo desempenho técnico nas análises efetuadas. Entretanto, seu potencial como base de dados é amplamente reconhecido pelo INCRA, que ainda utiliza tais imagens. O declínio da vida útil do Landsat-5 atribui mais importância ao lançamento do CBERS-2.<br>Technical and economical analyses were performed on IKONOS, Landsat TM 5 and Landsat ETM+ 7 and CCD/CBERS data in order to verify their feasibilities to subsidy agrarian reform projects. Results showed that IKONOS data presented excellent technical viability but its high cost prevents its use. Landsat ETM+ 7 data, with low cost, presented good technical viability, however due to the problems occurring in the satellite operation, its use was also prevented . CCD/CBERS data presented the second best similarity with the ground truth data, although it has presented the small kappa statistic index for the classification. With the launch of the CBERS 2, along with its low cost and possible radiometry correction, it is expected that CCD/CBERS can become a good source of data for agrarian reform projects. Landsat TM 5 data presented the worst technical viability, however, its low cost and potential use as data base is recognized by INCRA, which continues using it as the major source of data for agrarian reform projects

    Body appreciation around the world: Measurement invariance of the Body Appreciation Scale-2 (BAS-2) across 65 nations, 40 languages, gender identities, and age

    The Body Appreciation Scale-2 (BAS-2) is a widely used measure of a core facet of the positive body image construct. However, extant research concerning measurement invariance of the BAS-2 across a large number of nations remains limited. Here, we utilised the Body Image in Nature (BINS) dataset - with data collected between 2020 and 2022 - to assess measurement invariance of the BAS-2 across 65 nations, 40 languages, gender identities, and age groups. Multi-group confirmatory factor analysis indicated that full scalar invariance was upheld across all nations, languages, gender identities, and age groups, suggesting that the unidimensional BAS-2 model has widespread applicability. There were large differences across nations and languages in latent body appreciation, while differences across gender identities and age groups were negligible-to-small. Additionally, greater body appreciation was significantly associated with higher life satisfaction, being single (versus being married or in a committed relationship), and greater rurality (versus urbanicity). Across a subset of nations where nation-level data were available, greater body appreciation was also significantly associated with greater cultural distance from the United States and greater relative income inequality. These findings suggest that the BAS-2 likely captures a near-universal conceptualisation of the body appreciation construct, which should facilitate further cross-cultural research
