Authors: Xue Honghai , Gao Siyu , Zheng Na , Li Ming , Wen Xue , Wei Xindong 
Published: July 2019

Abstract
The frequent detection of antibiotics in water bodies gives rise to concerns about their removal technology. In this study, the degradation kinetics and mechanisms of norfloxacin (NOR), a typical fluoroquinolone pharmaceutical, by the UV/peroxydisulfate (PDS) was investigated. NOR could be degraded effectively using this process, and the degradation rate increased with the increasing dosage of PDS but decreased with the increasing concentration of NOR. In real water, the degradation of NOR was slower than that in ultrapure water, which indicated that laboratory results cannot be directly used to predict the natural fate of antibiotics. Further experiments suggested that the degradation of NOR was the most fast under neutral condition, the existence of HA or FA inhibited the degradation of NOR, and the presence of inorganic ions (NO3−, Cl−, CO32− and HCO3−) had no significant effect on degradation of NOR. Total organic carbon (TOC) removal rate (40%) indicated NOR was not completely mineralized, and six transformation products were identified, and possible degradation pathways of NOR had been proposed. It can be prospected that UV/PDS technology could be used for advanced treatment of wastewater containing fluoroquinolones.

Abstract
Untreated combined sewer overflows (CSOs) cause serious water pollution problems. In this study, the effects of CSO-induced heavy metals and the remediation practice of installation of a long-term water diversion (LTWD) on the microbial environment in river sediments were analyzed in an inland river. The Zn, Cd, Cr, and Cu contents in sediments and water were analyzed. DNA extraction and polymerase chain reaction analysis were conducted based on the Illumina MiSeq platform. The results showed that CSOs have a significant adverse impact on the diversity of microbial populations in river sediments. The LTWD is helpful in improving the richness of microorganisms and the proportion of Gram −ves, but it is challenging to reduce the accumulation of heavy metals in the sediment. The correlation analysis shows a strong relationship between some metabolic pathways and Zn and Cd accumulation in river sediments. Some detoxification compound metabolisms are also promoted at these sites. Thus, chronic exposure to environmental heavy metals from CSOs decreases the river microbial community, and further affects the ecological environment of the river. Therefore, without eliminating CSOs or reducing overflow frequency, it is difficult to alleviate the accumulation of heavy metals in river sediments and improve river ecology via water diversion alone.

Published: July 2019

Background:Endogenous opioids are neuropeptides involved in pain-relieving processes. In the periphery, they are synthesised and stored in cells of the immune system.Objective:In the current study, we describe the influence of perioperative, intravenous (i.v.) lidocaine infusion in children on postoperative, serum endogenous opioid concentrations in children.Methods:Forty-four children undergoing major spinal surgery were enrolled in the cohort study. They were divided into two groups: group A (n = 21) generally anesthetised with fentanyl, propofol, rocuronium, a mixture of oxygen/air/sevoflurane and with analgetics and co-analgetics: morphine, acetaminophen, metamizole, gabapentin, dexamethason and group B (n = 23) where, in addition to the above-described general anesthesia, patients were given i.v. lidocaine as a co-analgesic. We also recruited 20 healthy age- and gender-matched children (group C). We measured endogenous opioid levels in serum using immunoenzymatic methods. We evaluated postoperative pain intensity using a numerical or visual pain scale and demand for morphine.Results:The levels of measured endogenous opioids were similar in the control and in the studied groups before surgery. We noted that group B patients had lower pain intensity when compared to group A subjects. In group B, the elevated serum concentrations of β -endorphin, enkephalin and dynorphin in the postoperative period were reported. We also observed that the levels of endogenous opioids negatively correlated with morphine requirements and positively correlated with lidocaine concentration.Conclusion:Multidrug pain management including lidocaine seems to be more efficient than models without lidocaine. The endogenous opioid system should be considered as a novel target for pain relief therapy in children.
Development and Implementation of the Portable Operating Room Tracker App With Vital Signs Streaming Infrastructure: Operational Feasibility Study
Authors: Görges Matthias , West Nicholas C , Petersen Christian L , Ansermino J Mark 
Published: July 2019

Background
In the perioperative environment, a multidisciplinary clinical team continually observes and evaluates patient information. However, data availability may be restricted to certain locations, cognitive workload may be high, and team communication may be constrained by availability and priorities. We developed the remote Portable Operating Room Tracker app (the telePORT app) to improve information exchange and communication between anesthesia team members. The telePORT app combines a real-time feed of waveforms and vital signs from the operating rooms with messaging, help request, and reminder features.

Objective
The aim of this paper is to describe the development of the app and the back-end infrastructure required to extract monitoring data, facilitate data exchange and ensure privacy and safety, which includes results from clinical feasibility testing.

Methods
telePORT’s client user interface was developed using user-centered design principles and workflow observations. The server architecture involves network-based data extraction and data processing. Baseline user workload was assessed using step counters and communication logs. Clinical feasibility testing analyzed device usage over 11 months.

Results
telePORT was more commonly used for help requests (approximately 4.5/day) than messaging between team members (approximately 1/day). Passive operating room monitoring was frequently utilized (34% of screen visits). Intermittent loss of wireless connectivity was a major barrier to adoption (decline of 0.3%/day).

Conclusions
The underlying server infrastructure was repurposed for real-time streaming of vital signs and their collection for research and quality improvement. Day-to-day activities of the anesthesia team can be supported by a mobile app that integrates real-time data from all operating rooms.

Published: July 2019

Background and objectives
We investigated whether the recent growth in home dialysis use was proportional among all racial/ethnic groups and also whether there were changes in racial/ethnic differences in home dialysis outcomes.

Design, setting, participants, & measurements
This observational cohort study of US Renal Data System patients initiating dialysis from 2005 to 2013 used logistic regression to estimate racial/ethnic differences in home dialysis initiation over time, and used competing risk models to assess temporal changes in racial/ethnic differences in home dialysis outcomes, specifically: (1) transfer to in-center hemodialysis (HD), (2) mortality, and (3) transplantation.

Results
Of the 523,526 patients initiating dialysis from 2005 to 2013, 55% were white, 28% black, 13% Hispanic, and 4% Asian. In the earliest era (2005–2007), 8.0% of white patients initiated dialysis with home modalities, as did a similar proportion of Asians (9.2%; adjusted odds ratio [aOR], 0.95; 95% confidence interval [95% CI], 0.86 to 1.05), whereas lower proportions of black [5.2%; aOR, 0.71; 95% CI, 0.66 to 0.76] and Hispanic (5.7%; aOR, 0.83; 95% CI, 0.86 to 0.93) patients did so. Over time, home dialysis use increased in all groups and racial/ethnic differences decreased (2011–2013: 10.6% of whites, 8.3% of blacks [aOR, 0.81; 95% CI, 0.77 to 0.85], 9.6% of Hispanics [aOR, 0.94; 95% CI, 0.86 to 1.00], 14.2% of Asians [aOR, 1.04; 95% CI, 0.86 to 1.12]). Compared with white patients, the risk of transferring to in-center HD was higher in blacks, similar in Hispanics, and lower in Asians; these differences remained stable over time. The mortality rate was lower for minority patients than for white patients; this difference increased over time. Transplantation rates were lower for blacks and similar for Hispanics and Asians; over time, the difference in transplantation rates between blacks and Hispanics versus whites increased.

Conclusions
From 2005 to 2013, as home dialysis use increased, racial/ethnic differences in initiating home dialysis narrowed, without worsening rates of death or transfer to in-center HD in minority patients, as compared with white patients.

Es necesario reflexionar sobre las propuestas pedagógicas de diferentes autores contemporáneos, dando especial énfasis a aquellos que, de alguna u otra forma, cuestionan el sistema educativo tradicional, realizando una crítica profunda de la acción educativa, pero dando argumentos y propuestas concretas en beneficio de la educación y generando esperanza en quienes participan del hecho educativo. Tal es el caso de Paulo Freire, que ve en la educación una herramienta para el desarrollo de la libertad, siendo la esperanza un primer momento en dicho anhelo. Por su parte, Bertrand Russell apuesta por el fortalecimiento de una educación con sentido crítico, desde el rescate del individuo frente a la masa. Mientras tanto, Iván Illich manifiesta su descontento por los procesos de escolarización de los sujetos y de su pensamiento, proponiendo el desarrollo de una sociedad desescolarizada.Palabras claves: Freire, Russell, Illich, educación, liberación y esperanza.Abstract It is necessary to reflect on the educational proposals of different contemporary authors, with special emphasis on those, who in some way or another question the traditional educational system, conducting a thorough review of educational action, but giving arguments and concrete proposals for the benefit of education and generating hope for those involved in the educational process.

Published: July 2019

Las acciones que se genera en el aula como ambiente de aprendizaje son fundamentales para propiciar sinergias de trabajo armónico y de interés entre docentes y estudiantado. Las cuales deberán tener como finalidad un aprendizaje motivante de la disciplina. El objetivo de este trabajo fue evidenciar de manera discreta y preliminar, los tipos de relaciones-interacciones que se desarrollan en las lecciones de biología en un colegio secundario de la ciudad de Heredia de Costa Rica y cómo contribuyen a la construcción y comprensión del conocimiento que se promueve en el programa del Ministerio de Educación de Costa Rica. Se trabajó mediante un estudio de caso, aplicando la técnica de observación participante en aula(OP), entrevistas a estudiantes(EE), docente(EP) y un grupo focal(GF).Entre los resultados se destaca que la ecología de aula (relaciones sociales, afectivas y emocionales que se desarrollan durante la interacción) favorece el interés hacia el aprendizaje por parte de los estudiantes. Se discute acerca de la valoración de la reflexión teórica sobre la ciencia y su significado en el mundo, no sólo para favorecer ambientes que potencien el aprendizaje, sino que junto a ello, para que docentes y estudiantes desarrollen competencias de pensamiento científico que les permita ‘leer el mundo’ y valorar el conocimiento.

A Cultura do Partejar: Entre a Ancestralidade e a Modernidade
Authors: Santos Cledineia Carvalho 
Published: July 2019

Este estudo sobre as parteiras e o ato de partejar em tempos pós-modernos visa compreender como as parteiras idosas se percebem no atual contexto visto que a atividade de partejar em casa tem sido cada vez mais substituída pelo atendimento hospitalar.A pesquisa teve com sujeitos duas mulheres parteiras idosas da região do entorno da Comunidade Quilombola de Nova Esperança na zona rural do município de Wenceslau Guimarães Bahia. Essa discussão passa impreterivelmente pelas histórias de vida de duas mulheres idosas que em outrora dedicaram suas vidas em prol de outras mulheres de comunidades rurais. Será necessário refletir como se davam as relações entre a gestante e a parteira, durante e pós-parto e de que maneira estas mulheres parteiras se veem atualmente neste novo contexto social e cultural onde esta prática tem sido cada vez menos solicitada e,paralelamente, a isto acontece esquecimento da importância do legado que estas mulheres construíram ao longo de sua vida. Neste estudo utiliza-se o método Narrativo tendo como aporte a técnica da História Oral de Vida por meio de entrevistas abertas gravadas que se constituem como importante mecanismo que possibilita as colaboras falar sobre si, o que torna a pesquisa rica de subjetividades e memória. O artigo será desenvolvido a partir das categorias Gênero, Identidade, Velhice, Esquecimentos e Pós-modernidades, a partir deteóricoscomo:HebertMarcuse(1975); Michael Pollak (1989);ZygmuntBauman(1997);Joan Scott (1995); Stuart Hall (2014); SigmundFreud (2011); GrinDebert (2004) ; YuvalHarari(2016), dentre outros.

O objetivo deste estudo é evidenciar fatos estilizados dos fundos de Private Equity no Brasil, a fim de compreender como se dá essa modalidade de investimento no mercado de capitais brasileiro. Para tanto, utilizou-se de dados secundários de 12 fundos que possuem domicílio no Brasil e investem em empresas brasileiras. Os dados foram obtidos através do sistema de informações da Bloomberg. Os resultados mostram que o benchmark mais utilizado pelos fundos estudados foi o DI-Cetip, o Fix TRX Des Imob I possui o maior retorno, o Brasil Invest 2014 I FIP tem o maior risco da amostra, e o Barao Vermelho FIP o menor. Quanto ao tracking error, o fundo que apresentou maior afastamento do benchmark foi o Brasil Invest 2014 I FIP. Além disso, foi observado beta negativo em diversos fundos, o que reforça a ideia de que existem medidas mais adequadas que o beta para avaliar o risco dos países com mercados emergentes. No geral, o fundo FIP TRX Des Imob I apresentou o melhor desempenho dos fundos analisados, não só pela boa performance nos índices IS, IT, Alfa de Jensen e Isor, mas também por ser um dos mais aderentes ao benchmark e possuir uma das menores volatilidades da amostra. Por outro lado, o fundo Brasil Invest 2014 FIP apresentou a menor aderência ao benchmark, além de ser o fundo mais volátil da amostra.

The Indian Diaspora is a wonderful place to write from, and I am lucky to be a part of it-Kiran Desai
Indian Women writers like Kiran Desai, BhartiMukherjeee, Chitra Banerjee, Jumpa Lahiri all are dealing with the issues of Diasporic Consciousness, dislocation, displacement and immigrant experiences in their writings. Shauna Singh Baldwin, a Canadian-American writer of Indian origin is one of the most significant writers of Indian diaspora writing experiences of Sikh community during partition of Indian and its aftermath. In molding the personality of Shauna Singh Baldwin, the concept of nation, home and belongingness to the place of origin finds an important role. She has adopted and assimilated the elements of both home and host cultures and that is clearly revealed through her writings. As she says: “I wrote because I needed to make sense of my world by describing it. Eventually the stories weren't about me and my experience, but about situations, problems, feelings, metaphors and images that just refuse to go away.”
