Sepse tardia em Unidade de Tratamento Intensivo Neonatal

Justificativa e Objetivos: É essencial conhecer os microrganismos presentes em hemoculturas de pacientes pediátricos internados para uma melhor escolha da terapêutica antibiótica. Dessa forma, este trabalho tem como objetivo verificar a associação entre parâmetros clínicos e epidemiológicos com o desenvolvimento de sepse neonatal tardia em pacientes internados em um serviço de pediatria de um hospital do sul do Brasil. Métodos: Estudo transversal, descritivo, retrospectivo e qualiquantitativo que utilizou dados secundários oriundos dos prontuários de pacientes que apresentaram critérios clínicos para sepse neonatal, internados na Unidade de Tratamento Intensivo Neonatal (UTIN) do Hospital Santa Cruz. Resultados: Dos 588 pacientes internados na UTIN do Hospital Santa Cruz no período de 01/01/2013 a 31/12/2015, 123 recém-nascidos (RNs) preencheram os critérios para sepse neonatal tardia. Destes, 59 (47,97%) apresentaram hemocultura positiva, o que foi mais frequente em RNs prematuros (39,84%) e de baixo peso (43,90%), embora não tenha havido associação estatisticamente significativa entre estes fatores e hemocultura positiva. Dentre os possíveis fatores de risco para o desenvolvimento de sepse neonatal, o uso de ventilação mecânica (p=0,005), realização de cirurgia (p=0,019) e permanência no hospital por mais de um mês (p=0,001) apresentaram associação estatística com hemocultura positiva. Os microrganismos presentes em maior frequência nas hemoculturas foram os estafilococos coagulasenegativa (S. epidermidis, S. saprophyticus e S. haemolyticus), encontrados em 35,71% das hemoculturas analisadas. Conclusão: O estudo evidenciou maior prevalência de sepse neonatal tardia em RNs prematuros e de baixo peso, que necessitaram de maiores cuidados e foram submetidos a maior manipulação durante a permanência na UTIN.

Sepse tardia em Unidade de Tratamento Intensivo Neonatal

Background and Objectives: It is essential recognize the microorganisms present in hemoculture in pediatric patients internees for a better choice of antibiotic therapy. In this way, this work aims assess the association between clinical and epidemiological parameters with the onset of late neonatal sepsis in hospitalized patients, in a pediatric service of the south of Brazil. Methods: A cross-sectional, descriptive, retrospective, qualitative and quantitative study that used secondary data from the files of patients which presented clinical criteria indicating neonatal sepsis, that were hospitalized in the Neonatal Intensive Care Unit (NICU) at Hospital Santa Cruz. Results: Out of the 588 patients hospitalized in the NICU from 01/01/2013 to 12/31/2015, 123 newborns (NBs) filled the criteria for late neonatal sepsis. Out of these, 59 (47,97%) presented with positive hemoculture, which was more frequent in preterms NBs (39,84%) and low birth weight (43,90%), although there was no statistically significant associantion between these factors and positive hemoculture. From the possible risk factors for the onset of neonatal sepsis, mechanical ventilation (p=0,005), having performed surgery (p=0,019) and in-hospital stay longer than a month (p=0,001) showed statistic association with positive hemoculture. The microrganisms that were the most frequent were the coagulasenegative staphylococci (S. epidermidis, S. saprophyticu and S. haemolyticus), found in 37,71% of the analyzed hemocultures. Conclusion: This study showed higher prevalence of neonatal sepsis on premature NBs and on low-weight NBs that required higher care and suffered invasive procedures during the stay in the NICU. Invasive procedures and long hospital stay were significantly associated with positive hemoculture, corroborating with tah described in the literature.Justificación y Objetivos: Es esencial conocer los microorganismos presentes em las hemoculturas de pacientes pediátricos internados para una mejor elección de la terapia antibiótica.

Copyright: Copyright 2020 Elsevier B.V., All rights reserved.Background: Urine output is widely used as one of the criteria for the diagnosis and staging of acute renal failure, but few studies have specifically assessed the role of oliguria as a marker of acute renal failure or outcomes in general intensive care unit (ICU) patients. Using a large multinational database, we therefore evaluated the occurrence of oliguria (defined as a urine output 16 years) patients in the ICON audit who had a urine output measurement on the day of admission were included. To investigate the association between oliguria and mortality, we used a multilevel analysis. Results: Of the 8292 patients included, 2050 (24.7%) were oliguric during the first 24 h of admission. Patients with oliguria on admission who had at least one additional 24-h urine output recorded during their ICU stay (n = 1349) were divided into three groups: transient - oliguria resolved within 48 h after the admission day (n = 390 [28.9%]), prolonged - oliguria resolved > 48 h after the admission day (n = 141 [10.5%]), and permanent - oliguria persisting for the whole ICU stay or again present at the end of the ICU stay (n = 818 [60.6%]). ICU and hospital mortality rates were higher in patients with oliguria than in those without, except for patients with transient oliguria who had significantly lower mortality rates than non-oliguric patients. In multilevel analysis, the need for RRT was associated with a significantly higher risk of death (OR = 1.51 [95% CI 1.19-1.91], p = 0.001), but the presence of oliguria on admission was not (OR = 1.14 [95% CI 0.97-1.34], p = 0.103). Conclusions: Oliguria is common in ICU patients and may have a relatively benign nature if only transient. The duration of oliguria and need for RRT are associated with worse outcome.publishersversionPeer reviewe

Elective cancer surgery in COVID-19-free surgical pathways during the SARS-CoV-2 pandemic: An international, multicenter, comparative cohort study

PURPOSE As cancer surgery restarts after the first COVID-19 wave, health care providers urgently require data to determine where elective surgery is best performed. This study aimed to determine whether COVID-19–free surgical pathways were associated with lower postoperative pulmonary complication rates compared with hospitals with no defined pathway. PATIENTS AND METHODS This international, multicenter cohort study included patients who underwent elective surgery for 10 solid cancer types without preoperative suspicion of SARS-CoV-2. Participating hospitals included patients from local emergence of SARS-CoV-2 until April 19, 2020. At the time of surgery, hospitals were defined as having a COVID-19–free surgical pathway (complete segregation of the operating theater, critical care, and inpatient ward areas) or no defined pathway (incomplete or no segregation, areas shared with patients with COVID-19). The primary outcome was 30-day postoperative pulmonary complications (pneumonia, acute respiratory distress syndrome, unexpected ventilation). RESULTS Of 9,171 patients from 447 hospitals in 55 countries, 2,481 were operated on in COVID-19–free surgical pathways. Patients who underwent surgery within COVID-19–free surgical pathways were younger with fewer comorbidities than those in hospitals with no defined pathway but with similar proportions of major surgery. After adjustment, pulmonary complication rates were lower with COVID-19–free surgical pathways (2.2% v 4.9%; adjusted odds ratio [aOR], 0.62; 95% CI, 0.44 to 0.86). This was consistent in sensitivity analyses for low-risk patients (American Society of Anesthesiologists grade 1/2), propensity score–matched models, and patients with negative SARS-CoV-2 preoperative tests. The postoperative SARS-CoV-2 infection rate was also lower in COVID-19–free surgical pathways (2.1% v 3.6%; aOR, 0.53; 95% CI, 0.36 to 0.76). CONCLUSION Within available resources, dedicated COVID-19–free surgical pathways should be established to provide safe elective cancer surgery during current and before future SARS-CoV-2 outbreaks

ATLANTIC EPIPHYTES: a data set of vascular and non-vascular epiphyte plants and lichens from the Atlantic Forest

Epiphytes are hyper-diverse and one of the frequently undervalued life forms in plant surveys and biodiversity inventories. Epiphytes of the Atlantic Forest, one of the most endangered ecosystems in the world, have high endemism and radiated recently in the Pliocene. We aimed to (1) compile an extensive Atlantic Forest data set on vascular, non-vascular plants (including hemiepiphytes), and lichen epiphyte species occurrence and abundance; (2) describe the epiphyte distribution in the Atlantic Forest, in order to indicate future sampling efforts. Our work presents the first epiphyte data set with information on abundance and occurrence of epiphyte phorophyte species. All data compiled here come from three main sources provided by the authors: published sources (comprising peer-reviewed articles, books, and theses), unpublished data, and herbarium data. We compiled a data set composed of 2,095 species, from 89,270 holo/hemiepiphyte records, in the Atlantic Forest of Brazil, Argentina, Paraguay, and Uruguay, recorded from 1824 to early 2018. Most of the records were from qualitative data (occurrence only, 88%), well distributed throughout the Atlantic Forest. For quantitative records, the most common sampling method was individual trees (71%), followed by plot sampling (19%), and transect sampling (10%). Angiosperms (81%) were the most frequently registered group, and Bromeliaceae and Orchidaceae were the families with the greatest number of records (27,272 and 21,945, respectively). Ferns and Lycophytes presented fewer records than Angiosperms, and Polypodiaceae were the most recorded family, and more concentrated in the Southern and Southeastern regions. Data on non-vascular plants and lichens were scarce, with a few disjunct records concentrated in the Northeastern region of the Atlantic Forest. For all non-vascular plant records, Lejeuneaceae, a family of liverworts, was the most recorded family. We hope that our effort to organize scattered epiphyte data help advance the knowledge of epiphyte ecology, as well as our understanding of macroecological and biogeographical patterns in the Atlantic Forest.

The Gaia mission

Gaia is a cornerstone mission in the science programme of the EuropeanSpace Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach. Both the spacecraft and the payload were built by European industry. The involvement of the scientific community focusses on data processing for which the international Gaia Data Processing and Analysis Consortium (DPAC) was selected in 2007. Gaia was launched on 19 December 2013 and arrived at its operating point, the second Lagrange point of the Sun-Earth-Moon system, a few weeks later. The commissioning of the spacecraft and payload was completed on 19 July 2014. The nominal five-year mission started with four weeks of special, ecliptic-pole scanning and subsequently transferred into full-sky scanning mode. We recall the scientific goals of Gaia and give a description of the as-built spacecraft that is currently (mid-2016) being operated to achieve these goals. We pay special attention to the payload module, the performance of which is closely related to the scientific performance of the mission. We provide a summary of the commissioning activities and findings, followed by a description of the routine operational mode. We summarise scientific performance estimates on the basis of in-orbit operations. Several intermediate Gaia data releases are planned and the data can be retrieved from the Gaia Archive, which is available through the Gaia home page. http://www.cosmos.esa.int/gai

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Abstract Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Informalidad laboral, pobreza y regiones. Un análisis desde la coyuntura argentina

El objetivo del presente trabajo es analizar comparativamente el impacto sobre la pobreza de la informalidad laboral en las distintas regiones argentinas. Los resultados obtenidos indican que el Empleo Informal reduce el nivel de ingreso entre un 53% y un 71%, y el empleo en el Sector Informal disminuye el nivel de salario entre un 46% y un 63%, según la región considerada. En tanto, la formalización de los empleados informales implica reducciones de la pobreza de entre un 10% y un 16%, y la erradicación del empleo en el Sector Informal conlleva disminuciones de la incidencia de la pobreza que se ubican entre el 7% y el 14%, según la región que se considere. La metodología adoptada consistió, en una primera etapa, en estimar el efecto ceteris paribus de la informalidad en la pobreza. De este modo, fue posible obtener el diferencial de ingreso laboral causado por la informalidad. Luego, sobre la base de las brechas salariales estimadas, se realizó una microsimulación de la incidencia de la pobreza en un escenario contrafactual en el que se formalizaran todos los ocupados informales (o los trabajadores del Sector Informal). Con este procedimiento, se pudo cuantificar el efecto de la informalidad en la pobreza.The aim of this study is to analyze the impact of labor informality in poverty in the Argentine regions. The results indicate that informal employment reduces the income level between 53% and 71%, and employment in the informal sector decreases the wage level between 46% and 63%, depending on the region. Meanwhile, the formalization of informal employees implies poverty reductions of between 10% and 16%, and the eradication of employment in the informal sector leads to decreases in the incidence of poverty that are located between 7% and 14% depending on the region under consideration. The methodology adopted consisted, in a first step, in estimating the ceteris paribus effect of informality in poverty. Thus, it was possible to obtain the differential labor income caused by informality. Then, based on the estimated wage gaps, it was conducted a microsimulation of the incidence of poverty in a counterfactual scenario in which all informal workers (or workers in the informal sector) formalize. It was thus possible to quantify the effect of informality in poverty.Fil: Mario, Agustin Angel. Consejo Nacional de Investigaciones Cientificas y Tecnicas.

Risk of disease relapse, safety and tolerability of SARS-CoV-2 vaccination in patients with chronic inflammatory neuropathies

Background and purpose: The aim was to evaluate the risk of relapse after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination, and its safety and tolerability, in patients with chronic inflammatory neuropathies. Methods: In this multicenter, cohort and case-crossover study, the risk of relapse associated with SARS-CoV-2 vaccination was assessed by comparing the frequency of relapse in chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) and multifocal motor neuropathy (MMN) patients who underwent or did not undergo vaccination. Frequency of relapse in the 3 months prior to and after vaccination, and safety and tolerability of SARS-CoV-2 vaccination, were also assessed. Results: In all, 336 patients were included (278 CIDP, 58 MMN). Three hundred and seven (91%) patients underwent SARS-CoV-2 vaccination. Twenty-nine patients (9%) did not undergo vaccination. Mild and transient relapses were observed in 16 (5%) patients (13 CIDP, 3 MMN) after SARS-CoV-2 vaccination and in none of the patients who did not undergo vaccination (relative risk [RR] 3.21, 95% confidence interval [CI] 0.19-52.25). There was no increase in the specific risk of relapse associated with type of vaccine or diagnosis. Comparison with the 3-month control period preceding vaccination revealed an increased risk of relapse after vaccination (RR 4.00, 95% CI 1.35-11.82), which was restricted to CIDP patients (RR 3.25, 95% CI 1.07-9.84). The safety profile of SARS-CoV-2 vaccination was characterized by short-term, mild-to-moderate local and systemic adverse events. Conclusions: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination in CIDP and MMN patients does not seem to be associated with an increased risk of relapse at the primary end-point, although a slightly increased risk in CIDP patients was found compared to the 3 months before vaccination
