Direct Percutaneous Endoscopic Jejunostomy Using Single-Balloon Enteroscopy without Fluoroscopy: a Case Series

BACKGROUND: Direct percutaneous endoscopic jejunostomy (DPEJ) is a useful method to provide enteral nutrition to individuals when gastric feeding is not possible or contraindicated. The aim of this study was to analyze the efficacy and safety of DPEJ tube placement with the Gauderer-Ponsky technique by the pull method, using single-balloon enteroscopy (SBE) without fluoroscopy. METHODS: This is a retrospective analysis of patients undergoing SBE for DPEJ placement in a referral hospital between January 2010 and March 2016. Technical success, clinical success and procedure related complications were recorded. RESULTS: Twenty-three patients were included (17 males, median age 71 years, range 37-93 years). The most frequent indications for DPEJ were gastroesophageal cancer (n = 10) and neurological disease (n = 8). Eighty-seven percent of the patients had a contraindication to percutaneous endoscopic gastrostomy (PEG) and PEG was unsuccessful in the remaining patients. The technical success rate was 83% (19/23), transillumination was not possible in three patients and an accidental exteriorization of the bumper resulting in a jejunal perforation occurred in one patient. The clinical success was 100% (19/19). The median follow-up was five months (range 1-35 months). Apart from the case of jejunal perforation and the two cases of accidental exteriorization, there were no other complications during follow-up. The 6-month survival was 65.8% and the 1-year survival was 49.3%. CONCLUSION: DPEJ can be carried out successfully via SBE without fluoroscopy with a low rate of significant adverse events. Although, leaving the overtube in place during the bumper pulling can be useful for distal jejunal loops, it can be safely removed in proximal loops to minimize complications.info:eu-repo/semantics/publishedVersio

Cholesterol affects African swine fever virus infection

African swine fever virus (ASFV) enters cells by receptor mediated endocytosis and requires a fusion event between the viral envelope and the limiting membrane of the endosome at low pH. In order to investigate the role of cholesterol in the early stages of ASFV infection, we have studied the effect of the removal of cell and viral membrane cholesterol by cholesterol oxidase treatment of cells and virions, as well as the effect of some inhibitors of cholesterol synthesis on the infectious pathway. In addition, we have investigated viral infection in cholesterol-depleted Vero cells. Both cholesterol-depleted and cholesterol oxidase-treated Vero cells were unaltered in their ability to bind or internalize the virus, but were blocked in ASFV fusion and subsequent virus replication. Our results indicate that ASFV infection is affected by cholesterol in the target membrane.http://www.sciencedirect.com/science/article/B6T1X-3V3N06F-2/1/e52e3430df628f470dc4b0b8400b4b2

Entanglement properties of optical coherent states under amplitude damping

Through concurrence, we characterize the entanglement properties of optical coherent-state qubits subject to an amplitude damping channel. We investigate the distillation capabilities of known error correcting codes and obtain upper bounds on the entanglement depending on the non-orthogonality of the coherent states and the channel damping parameter. This work provides a first, full quantitative analysis of these photon-loss codes which are naturally reminiscent of the standard qubit codes against Pauli errors.Comment: 7 pages, 6 figures.

Estratégias ambientais em grandes empresas com atividade galvânica no Rio Grande do Sul.

As pressões sociais sinalizam que os custos para adequação da empresa às demandas do meio ambiente podem se transformar em conscientização, pois a sociedade não mais aceita a exacerbação do lucro obtido às custas dos efeitos ambientais negativos. Assim, a proteção ambiental deixou de ser uma função exclusiva da produção para ser uma função da empresa, fazendo parte da estrutura organizacional e do planejamento estratégico. As empresas que possuem processos galvânicos são consideradas de alto impacto ambiental, devido ao grande consumo de água, energia, geração de emissões e resíduos sólidos perigosos. Conciliar a atividade produtiva com a sustentabilidade ambiental é um desafio enfrentado pelas empresas. Este contexto determinou o problema da pesquisa: qual o tipo e o foco das estratégias ambientais adotadas pelas grandes empresas do Rio Grande do Sul com atividade galvânica para o controle dos impactos negativos? O objetivo do trabalho foi identificar tipos de estratégias implantadas pelas empresas pesquisadas. Para a realização da pesquisa foi usado o método investigativo, a partir do estudo de caso em cinco grandes empresas. O estudo de caso permitiu identificar o potencial das empresas gaúchas para a implantação de estratégias preventivas que possibilitam reduzir perdas e a poluição ambiental
