    OBJETIVO: Avaliar o prognĂłstico dos pacientes com lesĂŁo iatrogĂȘnica da via biliar (LIVB) em relação ao tempo de referencia (TR) para a unidade de transplante hepĂĄtico (TH). MÉTODOS: Foram revisados 51 prontuĂĄrios de pacientes que sofreram algum tipo de LIVB durante a colecistectomia e que foram encaminhados para a unidade de TH no Hospital Geral de Bonsucesso (HGB). As lesĂ”es foram agrupadas de acordo com a classificação de Bismuth. AlĂ©m da colecistectomia (momento da lesĂŁo), tambĂ©m avaliamos o TR e o desfecho. RESULTADOS: Dentre os 51 pacientes estudados encontramos 17 homens e 34 mulheres com uma mĂ©dia de idade de 42,7 anos. Vinte e dois pacientes (43,1%) tinham uma lesĂŁo do tipo II; 13 (25,5 %) do tipo III; 10 (19,6 %) do tipo I, 5 (9,8 %) do tipo IV; e apenas um (2 %) do tipo V. Quarenta pacientes foram operados, sendo que trĂȘs nĂŁo retornaram para revisĂŁo mĂ©dica e portanto, 37 foram avaliados em relação ao desfecho. Dentre esses, 25 pacientes (67,6 %) tiveram resultados excelentes ou bons com TR mĂ©dio de 11,5 meses (intervalo: 2-48 meses) e 47,2 meses (intervalo: 3-180 meses) respectivamente. Os 12 pacientes (32,4 %) com resultados ruins tiveram um TR mĂ©dio de 65,9 meses (intervalo: 3-264 meses), que foi significativamente maior do que o grupo com resultados excelentes ou bons (p=0,004). Sete pacientes foram listadas para fila de TH, porĂ©m apenas dois foram realizados. O TR desses sete pacientes foi significativamente mais elevado (p=0,04) do que o daqueles pacientes nĂŁo listados. Sete pacientes morreram, dos quais seis foram causados por complicaçÔes hepĂĄticas. CONCLUSÃO: O TR influenciou significativamente no prognĂłstico dos pacientes da nossa amostra

    O objetivo deste artigo Ă© mostrar os aspectos mineralĂłgicos das "Viagens FilosĂłficas" realizadas no ImpĂ©rio portuguĂȘs na transição do sĂ©culo XVIII para o XIX, com ĂȘnfase no Brasil. Tais expediçÔes cientĂ­ficas e seus resultados inserem Portugal e suas possessĂ”es no contexto cientĂ­fico do perĂ­odo. Acreditamos que as "Viagens FilosĂłficas" estĂŁo entre os elementos mais relevantes para entender o processo de institucionalização das ciĂȘncias naturais no Brasil, particularmente - no caso deste artigo - as ciĂȘncias mineralĂłgicas.<br>The late eighteenth- and early nineteenth-century scientific expeditions undertaken by the Crown earned Portugal and its possessions a place on the period's scientific stage. These Philosophical Voyages provide us with invaluable elements for understanding the process by which the natural sciences were institutionalized in Brazil, especially - in the case of this article - the mineralogical sciences

    Geoeconomic variations in epidemiology, ventilation management, and outcomes in invasively ventilated intensive care unit patients without acute respiratory distress syndrome: a pooled analysis of four observational studies

    Background: Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods: In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings: Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference -1·69 [-9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5-8] vs 6 [5-8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52-23·52]; p&lt;0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75-0·86]; p&lt;0·0001). Interpretation: Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status
