    This article analyzes the experiences of História, Ciências, Saúde - Manguinhos (History, science, health), a journal published since 1994 by the House of Oswaldo Cruz, at the Oswaldo Cruz Foundation. The background being the difficulties faced by journals of the humanities, it discusses the pathway of HCS - Manguinhos until it is welcomed by the SciELO Portal, the resulting implications in regard of the editorial routines, the potential of dissemination and the perspectives of internationalization. Editors are viewed amidst currents of thought which express either convergent or contradictory opinions concerning: first, the processes underway to hierarchize and internationalize the Brazilian scientific journals; second, the ways to disseminate their contents and evaluate their impact; and, third, the quantitative and productivist tendencies that prevail today in the academic milieu. The paper describes difficulties arising from the effort of making HCS - Manguinhos international and analyzes the results achieved after joining the social networks, in June 2013, by making use of metrics different from those long ago defined to assess the impact of scientific publications.O presente artigo analisa experiências de História, Ciências, Saúde - Manguinhos, revista editada desde 1994 pela Casa de Oswaldo Cruz, da Fundação Oswaldo Cruz. Tendo como pano de fundo as dificuldades enfrentadas pelos periódicos da área de humanas, discute a trajetória de HCS - Manguinhos até seu ingresso no Portal SciELO, as implicações que isso teve no tocante às rotinas editoriais, ao potencial de veiculação e às perspectivas de internacionalização. Procura situar os editores em meio a correntes de pensamento que manifestam posições convergentes ou contraditórias a respeito: primeiro, dos processos em curso de hierarquização e internacionalização de periódicos científicos brasileiros; segundo, das formas de divulgar seus conteúdos e avaliar seu impacto; e, terceiro, das tendências quantitativistas e produtivistas hoje imperantes no meio acadêmico. Relata dificuldades enfrentadas no esforço para internacionalizar HCS - Manguinhos e analisa os resultados alcançados após o ingresso nas redes sociais, em junho de 2013, fazendo uso de métricas diferentes daquelas há mais tempo instituídas para aferir o impacto de publicações científicas

    6 págs.; 4 figs.; 2 tabs. 16th International Conference on X-ray Absorption Fine Structure (XAFS16) ; Open Access funded by Creative Commons Atribution Licence 3.0The local electronic and crystal structure of niobium-lead-germanate, Nb2O5-PbO- GeO2 (NPG), glass thin films on silicon substrates were probed by XANES and EXAFS. NPG glasses are promising candidates for applications in nonlinear optical devices because they exhibit interesting optical characteristics such as high nonlinear third order optical susceptibility. In this work NPG glasses were prepared with pulsed laser deposition method with varying oxygen partial pressure to induce thin films with different oxygen stoichiometry. Previously, it was shown that oxygen stoichiometry has a very important effect to produce unusual high optical susceptibility. Detailed EXAFS and XANES analyses in a series of NPG thin films revealed the subtle variations in the local environment around Nb atoms and the Nb oxidation states caused by oxygen deficiencies.

    Background: Literature suggests colonic resection and primary anastomosis (RPA) instead of Hartmann's procedure (HP) for the treatment of left-sided colonic emergencies. We aim to evaluate the surgical options globally used to treat patients with acute left-sided colonic emergencies and the factors that leading to the choice of treatment, comparing HP and RPA. Methods: This is a prospective, international, multicenter, observational study registered on ClinicalTrials.gov. A total 1215 patients with left-sided colonic emergencies who required surgery were included from 204 centers during the period of March 1, 2020, to May 31, 2020. with a 1-year follow-up. Results: 564 patients (43.1%) were females. The mean age was 65.9 ± 15.6 years. HP was performed in 697 (57.3%) patients and RPA in 384 (31.6%) cases. Complicated acute diverticulitis was the most common cause of left-sided colonic emergencies (40.2%), followed by colorectal malignancy (36.6%). Severe complications (Clavien-Dindo ≥ 3b) were higher in the HP group (P < 0.001). 30-day mortality was higher in HP patients (13.7%), especially in case of bowel perforation and diffused peritonitis. 1-year follow-up showed no differences on ostomy reversal rate between HP and RPA. (P = 0.127). A backward likelihood logistic regression model showed that RPA was preferred in younger patients, having low ASA score (≤ 3), in case of large bowel obstruction, absence of colonic ischemia, longer time from admission to surgery, operating early at the day working hours, by a surgeon who performed more than 50 colorectal resections. Conclusions: After 100 years since the first Hartmann's procedure, HP remains the most common treatment for left-sided colorectal emergencies. Treatment's choice depends on patient characteristics, the time of surgery and the experience of the surgeon. RPA should be considered as the gold standard for surgery, with HP being an exception

Avalia a participação dos médicos e de outras profissões de saúde no Sistema. Analisa ainda a emergência de políticas identitárias, ausentes na formulação do projeto da reforma sanitária, cuja ênfase era a igualdade.This interview with Lígia Bahia explores evaluations of the first 25 years of Brazil’s Sistema Único de Saúde (SUS) and analyzes the project’s progress, impasses, and missteps. Bahia is critical of both tendencies currently found within SUS: the one that sees the system as aimed at equity and the other posing equality as its goal. She criticizes the ambivalence that various spheres of government have displayed in their decisions regarding large corporate groups and private health insurance plans, which conflict with the ideas of SUS. She evaluates the participation of doctors and other healthcare professionals in the system. Lastly, she analyzes the emergence of identity politics, which are missing from the public health reform project, whose emphasis was on equality
