    Chromobacterium violaceum is one of millions of species of free-living microorganisms that populate the soil and water in the extant areas of tropical biodiversity around the world. Its complete genome sequence reveals (i) extensive alternative pathways for energy generation, (ii) ≈500 ORFs for transport-related proteins, (iii) complex and extensive systems for stress adaptation and motility, and (iv) wide-spread utilization of quorum sensing for control of inducible systems, all of which underpin the versatility and adaptability of the organism. The genome also contains extensive but incomplete arrays of ORFs coding for proteins associated with mammalian pathogenicity, possibly involved in the occasional but often fatal cases of human C. violaceum infection. There is, in addition, a series of previously unknown but important enzymes and secondary metabolites including paraquat-inducible proteins, drug and heavy-metal-resistance proteins, multiple chitinases, and proteins for the detoxification of xenobiotics that may have biotechnological applications

    O Programa de Hepatopatias do Hospital da Fundação Santa Casa de MisericĂłrdia do ParĂĄ surgiu pela necessidade de prestar assistĂȘncia a hepatopatas na regiĂŁo amazĂŽnica priorizando assistĂȘncia qualificada, identificação das etiologias, seguimento clĂ­nico, e tratamento direcionado. Este trabalho visa descrever dados relativos Ă  epidemiologia clĂ­nica, fatores etiolĂłgicos e anĂĄlise histopatolĂłgica. Dos 1469 pacientes avaliados, atravĂ©s de exames clĂ­nicos, laboratoriais, endoscĂłpicos e de imagem e/ou histopatolĂłgico, foram considerados hepatopatas crĂŽnicos 935 (63,6%). Nesta casuĂ­stica, a mĂ©dia de idade foi 50 anos, 666 (71,2%) do sexo masculino e maior procedĂȘncia de BelĂ©m. Os agentes etiolĂłgicos mais prevalentes foram alcoolismo (53,7%) e hepatites virais (39,1%). BiĂłpsia hepĂĄtica realizada em 403/935 (43,1%), demonstrou hepatite crĂŽnica (34%) e cirrose (34%) na maioria das amostras. Conclui-se, portanto, que a doença hepĂĄtica crĂŽnica na regiĂŁo Ă© mais prevalente no sexo masculino, sendo o alcoolismo a principal etiologia e mais da metade dos casos se encontravam em fase avançada no momento do diagnĂłstico

    O suporte ventilatĂłrio artificial invasivo e nĂŁo invasivo ao paciente crĂ­tico tem evoluĂ­do e inĂșmeras evidĂȘncias tĂȘm surgido, podendo ter impacto na melhora da sobrevida e da qualidade do atendimento oferecido nas unidades de terapia intensiva no Brasil. Isto posto, a Associação de Medicina Intensiva Brasileira (AMIB) e a Sociedade Brasileira de Pneumologia e Tisiologia (SBPT) - representadas pelo seus ComitĂȘ de Ventilação MecĂąnica e ComissĂŁo de Terapia Intensiva, respectivamente, decidiram revisar a literatura e preparar recomendaçÔes sobre ventilação mecĂąnica objetivando oferecer aos associados um documento orientador das melhores prĂĄticas da ventilação mecĂąnica na beira do leito, baseado nas evidencias existentes, sobre os 29 subtemas selecionados como mais relevantes no assunto. O projeto envolveu etapas visando distribuir os subtemas relevantes ao assunto entre experts indicados por ambas as sociedades que tivessem publicaçÔes recentes no assunto e/ou atividades relevantes em ensino e pesquisa no Brasil na ĂĄrea de ventilação mecĂąnica. Esses profissionais, divididos por subtemas em duplas, responsabilizaram-se por fazer revisĂŁo extensa da literatura mundial sobre cada subtema. Reuniram-se todos no Forum de Ventilação MecĂąnica na sede da AMIB em SĂŁo Paulo, em 03 e 04 de agosto de 2013 para finalização conjunta do texto de cada subtema e apresentação, apreciação, discussĂŁo e aprovação em plenĂĄria pelos 58 participantes, permitindo a elaboração de um documento final

    Evaluation of a quality improvement intervention to reduce anastomotic leak following right colectomy (EAGLE): pragmatic, batched stepped-wedge, cluster-randomized trial in 64 countries

    Background Anastomotic leak affects 8 per cent of patients after right colectomy with a 10-fold increased risk of postoperative death. The EAGLE study aimed to develop and test whether an international, standardized quality improvement intervention could reduce anastomotic leaks. Methods The internationally intended protocol, iteratively co-developed by a multistage Delphi process, comprised an online educational module introducing risk stratification, an intraoperative checklist, and harmonized surgical techniques. Clusters (hospital teams) were randomized to one of three arms with varied sequences of intervention/data collection by a derived stepped-wedge batch design (at least 18 hospital teams per batch). Patients were blinded to the study allocation. Low- and middle-income country enrolment was encouraged. The primary outcome (assessed by intention to treat) was anastomotic leak rate, and subgroup analyses by module completion (at least 80 per cent of surgeons, high engagement; less than 50 per cent, low engagement) were preplanned. Results A total 355 hospital teams registered, with 332 from 64 countries (39.2 per cent low and middle income) included in the final analysis. The online modules were completed by half of the surgeons (2143 of 4411). The primary analysis included 3039 of the 3268 patients recruited (206 patients had no anastomosis and 23 were lost to follow-up), with anastomotic leaks arising before and after the intervention in 10.1 and 9.6 per cent respectively (adjusted OR 0.87, 95 per cent c.i. 0.59 to 1.30; P = 0.498). The proportion of surgeons completing the educational modules was an influence: the leak rate decreased from 12.2 per cent (61 of 500) before intervention to 5.1 per cent (24 of 473) after intervention in high-engagement centres (adjusted OR 0.36, 0.20 to 0.64; P < 0.001), but this was not observed in low-engagement hospitals (8.3 per cent (59 of 714) and 13.8 per cent (61 of 443) respectively; adjusted OR 2.09, 1.31 to 3.31). Conclusion Completion of globally available digital training by engaged teams can alter anastomotic leak rates. Registration number: NCT04270721 (http://www.clinicaltrials.gov)
