Published: May 2019

Debido al incremento en casos reportados de crímenes tales como, delitos sexuales y hurtos en personas puestas en estado de indefensión cometidos bajo el efecto de drogas de abuso y evidencias de intoxicaciones accidentales, suicidas y homicidas asociadas al consumo de estas, se hace necesario el desarrollo de técnicas analíticas, selectivas, sensibles y confi ables para la determinación de las drogas en muestras biológicas en casos de interés forense. Se validó un método para la determinación de morfi na, codeína, 6-acetilmorfi na y metadona, en orina y sangre. Los porcentajes de recuperación fueron superiores a 56% y 63% para todos los analitos evaluados en orina y sangre respectivamente. Las curvas de calibración fueron lineales con coefi cientes de correlación superiores a 0.98, dentro del rango dinámico asociado a las concentraciones tóxicas o letales reportadas en la literatura. Las CMD y CMC de cada analito se determinaron estadísticamente a partir de las curvas de calibración construidas. La precisión tuvo coefi cientes de variación inferiores a 24% para los analitos. Se obtuvo para codeína en orina 78.9% de valor predictivo positivo y en sangre 100%, igual que para morfi na en orina. 

El método desarrollado se aplicó exitosamente para la resolución de casos forenses de accidentes de tránsito, muertes en estudio, determinación de embriaguez no alcohólica y envenenamiento suicida o accidental.

Published: May 2019

Una de las causas de muerte más comunes entre la población femenina a nivel mundial es el cáncer de seno, además de ser una de las formas de cáncer más prevalente entre otros tipos de cáncer. El diagnóstico temprano y oportuno es un factor determinante para un tratamiento adecuado de esta enfermedad, incrementando las probabilidades de supervivencia de quienes lo padecen. Con el fin de mejorar la eficiencia y la efectividad del diagnóstico del cáncer de seno, se implementó un sistema de análisis de imágenes, cuyo propósito es servir de apoyo para los radiólogos en la detección de lesiones en las mamografías.

Con el fin de encontrar e identificar lesiones mamarias en las mamografías, se implementaron técnicas de segmentación de imágenes en una Región de Interés (ROI), la cual está relacionada con el área donde está concentrada la densidad mamaria. La densidad mamaria se define como el área más brillante en la imagen mamográfica y que está compuesta por tejido fibroglandular y adiposo; es allí donde es probable que las lesiones mamarias sean expuestas. Este estudio provee una metodología dividida en dos etapas, usando dos técnicas de segmentación principales: 1- una técnica de crecimiento de regiones y 2- una técnica de división y fusión de regiones. Este estudio, además, provee una descripción completa del análisis de las imágenes y las herramientas utilizadas para el desarrollo de los algoritmos.

Published: May 2019

En este proyecto se hace el control de las extremidades superiores de una plataforma robótica humanoide utilizando la técnica de motion retargeting, que redirige los movimientos de un operador humano al androide. El sistema propuesto hace uso del microsoft kinect para reconocer las articulaciones del operador, posteriormente hace un cambio de coordenadas, verificación de los límites de los ángulos permitidos por la plataforma y finalmente se transmiten los movimientos al robot para que 'imite' los movimientos del operador, actualmente el sistema reproduce dos grados de libertad en cada hombro, uno en cada codo y uno en la cintura. Con este proyecto se pueden realizar rutinas de movimientos para la plataforma sin necesidad de marcas especiales y/o cables sobre el operario, y se evitan procedimientos invasivos
COMPENSACIÓN DE LOS EFECTOS DISPERSIVOS DE LA FIBRA ÓPTICA EN UN SISTEMA IM-DD USANDO ECUALIZACIÓN LMS Y MLSE

Published: May 2019

Actualmente en Colombia ha comenzado el despliegue de la fibra óptica hasta el hogar, con el fin de que los operadores de telecomunicaciones ofrezcan servicios de mayor capacidad, aprovechando el gran ancho de banda que proporciona la fibra óptica. Para la masificación de esta tecnología y el cubrimiento de todos los usuarios finales, las redes deben ser de bajo costo, por lo cual los sistemas modulados en intensidad con detección directa (IM-DD) siguen vigentes a pesar de las ventajas de los receptores ópticos coherentes. No obstante, en los sistemas IM-DD, las señales transmitidas se ven más afectadas ante las imperfecciones de la fibra óptica como lo es la dispersión cromática, causante de la interferencia inter-símbolo, la cual provoca el aumento de la tasa de error de bit (BER). En este artículo se presenta una red óptica IM-DD simulada en Virtual Photonics®(VPI), para transmisión de señales con modulación No-Return-to-Zero On-Off-Keying (NRZ-OOK) de hasta 40 Gbps, con longitudes de fibra óptica monomodo estándar hasta de 80 km. Se plantea la compensación de los efectos del canal óptico mediante la ecualización eléctrica usando el algoritmo de LMS (Least-Mean-Square), estimando los coeficientes del canal a través de secuencias de entrenamiento, presentando una reducción significativa del BER a 10 Gbps con respecto a la relación señal a ruido (SNR). Además, se comparan los resultados con un ecualizador MLSE (Maximunlikelihood sequence estimation), el cual reduce en menor medida el BER en comparación a la ecualización LMS..

Comparative study of a winter wheat variety and hybrid sown after different pre-crops on chernozem soil
Authors: Fekete Ágnes , Pepó Péter
Published: May 2019

Wheat production is a determining branch within Hungarian crop production (produced on nearly one million hectares). Weather anomalies caused by climatic change confirmed the importance of the biological background (variety, hybrid) in wheat production. The adapting ability and reaction of different wheat genotypes towards nutrient supply were studied in a long-term field experiment on chernozem soil type in the case of different pre-crops (sunflower and maize). According to the experimental results of the vegetation of 2017/2018, the yield of the variety Ingenio sown after the sunflower as previous crop ranged between 4168 and 8734 kg ha-1, while in the case of maize as previous crop, this value ranged between 2084 and 7782kg ha-1, depending on the applied nutrient supply level. The studied genotypes produced rather significant yield surplus as a response to the application of mineral fertilization (4.6–5.1 t ha-1 after sunflower and 5.7–6.3 t ha-1 after maize). Optimal mineral fertilizer dosage was determined by both the genotype and the pre-crop. N-optimum values of wheat genotypes was determined using regression analysis. In the case of the variety Ingenio sown after sunflower, the optimum range was N144-150+PK, while after maize, it was N123-150+PK, respectively. For the hybrid Hyland, these optimum ranges were N114-120+PK, just as N150-153+PK, resp. The application of optimal mineral fertilizer dosages improved water utilization of the studied wheat genotypes to a significant extent. WUE values of the control, unfertilized treatments ranged between 4.1–8.3 kg mm-1, while in optimal fertilizer treatment, it ranged between 15.5 and 17.4 kg mm-1.

Published: May 2019

Os temas “dançar conforme a música”, “fazer a música para dançar” e “dançar sem música” pretendem despertar a curiosidade, desenvolver a autonomia e estimular as percepções de alunos e de professores envolvidos no cotidiano escolar. Dessa forma, trazemos para este estudo, inserido na temática de práticas educativas transformadoras e solidárias, algumas reflexões sobre a importância do professor na perspectiva da aprendizagem, como sujeito que preconiza atos em uma aula que podem, muitas vezes, ser considerados como obra de arte, dependendo da mediação por ele realizada na construção do conhecimento. Ressaltamos nesse estudo, as possibilidades de novas formas de olhar a escola por meio de uma Pedagogia escolar e social que conduza a práticas inclusivas e socializadoras. Nesse sentido, este texto avança a partir da metáfora do ouvir e dançar como práticas sensíveis, artísticas, estéticas e interdisciplinares, em um diálogo com Duarte Jr., Katrup, Meira, Rancière, Schafer e Uriarte sobre a educação emancipatória e autônoma dos envolvidos. Procuramos ressaltar a importância do aprender por meio de constante atualização na área específica e na conexão com a vida social e a natureza, compreendendo que o aprender das artes é tanto uma atividade cognitiva como cinestésica, e que não há aprendizagem sem inscrição corporal.
Educação do campo e pedagogia social: interculturalidade em lutas coletivas por terra e educação
Authors: Foerste Erineu , Fichtner Bernd , Nunes José Wálter , Souza Neto João Clemente de
Published: May 2019

O artigo objetiva discutir Educação do Campo como prática de Pedagogia Social. As análises focam a problemática das lutas por terra e educação dos trabalhadores rurais, especialmente as Comunidades e Povos Tradicionais (Decreto 6.040/2010). Como a Educação do Campo trabalha as culturas e saberes dos trabalhadores rurais? Educação do Campo não é um conceito monovalente nem se restringe a processos de escolarização; pode ser definida como prática de interculturalidade (Fornet-Betancourt, 2001). Parte-se de abordagens investigativas sócio-históricas (Fichtner et al., 2013), para avaliação de documentos oficiais, reafirmando a educação enquanto direito dos cidadãos e dever do Estado. Práticas colaborativas interinstitucionais (Foerste, 2005) entre movimentos sociais, secretarias de educação, universidade etc. consideram povos, territórios, culturas e saberes tradicionais como dimensões articuladoras da construção coletiva de projetos pedagógicos da Educação do Campo como prática de Pedagogia Social.

El artículo que presentamos surge en el seno de una investigación cuyo objetivo se centra en la localización y análisis de propuestas de educación patrimonial (EP) en museos para personas con Trastorno del Espectro Autista (TEA). Para ello se ha seguido la línea metodológica creada por el Observatorio de Educación Patrimonial en España (OEPE) (Fontal, 2016), cuya novedad y relevancia reside, en este caso, en vincular dos aspectos hasta ahora no interrelacionados la EP y el TEA. Los resultados obtenidos son muy clarificadores porque muestran escasas experiencias en un contexto que cuenta con una prevalencia de casos cada vez mayor.
BRICS e a educação superior. Questões e convergências possíveis?
Authors: De Araújo Borges Maria Creusa
Published: May 2019

O autor examina a convergência de políticas no ensino superior nas potências mundiais emergentes, particularmente nos BRICS (Brasil, Rússia, Índia, China e África do Sul). Considerando as relações de forças, posições de poder marcam e influenciam o espaço geopolítico. Dessa forma, a posse de capital relevante nos cenários econômico e político caracteriza o espaço em que a cooperação em tecnologia, educação e formação tem sido colocada na agenda política dos países do BRICS, especialmente desde a crise econômica desencadeada em 2008. Nesse cenário, a autora discute temas e tópicos referentes a possíveis convergências que devem ser construídas no ensino superior, com o objetivo de dar continuidade e fortalecer projetos de cooperação, ao centrar em áreas prioritárias para a consolidação da posição emergente dos países do BRICS. Assume-se que as estratégias regionais indicam a construção de uma agenda de cooperação com ênfase no par pesquisa/tecnologia, internacionalização e FEP (Formação e Educação Profissional). A agenda aqui proposta é desenhada com base em análise bourdieusiana de campo de forças e de capital.
As religiões afro-brasileiras na escola
Authors: Paiva de Carvalho Guilherme , Anselmo da Silva Eliane
Published: May 2019

O artigo aborda as representações de professores/as da educação básica sobre as religiões afro-brasileiras. Para tanto, o estudo utiliza um método qualitativo baseado na técnica de entrevista semiestruturada e na análise de conteúdo. A concepção de representação, formulada por teorias que compõe os estudos culturais, é uma referência para a análise da visão dos/as professores/as sobre as religiões afro-brasileiras. No sistema educacional brasileiro, as culturas africanas e afro-brasileiras tornaram-se conteúdos obrigatórios na educação básica com a Lei 10.639/2003, incorporada pela Lei 11.645/2008. Por outro lado, com o racismo simbólico constituído na história da sociedade brasileira, são construídas formas estereotipadas de representação e estigmas sobre as religiões afro-brasileiras. Os resultados da pesquisa mostram que formas estereotipadas de representação podem ser observadas na perspectiva de profissionais da educação básica que não tiveram contato com conhecimentos sobre as religiões afro-brasileiras.

Published: May 2019

Este artigo discute o impacto na atuação docente do programa de formação continuada desenvolvido em uma instituição localizada na Região Sul do Brasil, a Universidade do Vale do Itajaí – Univali. O objetivo é identificar se há alguma relação entre a atuação do professor e a adesão dele à formação continuada. A metodologia utilizada é quali-quantitativa. Os instrumentos de coleta de dados foram: a) média da carga horária do professor no Programa de Formação Continuada da Univali; b) média da nota resultante do Programa de Avaliação Institucional da Univali que afere a atuação docente; c) temáticas cursadas pelos professores. A coleta de dados se refere ao período compreendido entre o primeiro semestre de 2011 e o primeiro semestre de 2017. Ao todo foram analisados os dados de 69 professores da instituição de um conjunto de cerca de mil professores, tendo sido selecionados somente aqueles que participaram da formação continuada em todos os semestres nesse intervalo e foram avaliados pelos discentes nesses mesmos semestres. O aporte teórico principal utilizado para discussão dos dados foi Nóvoa (2000), Sá et al.(2017), Franco (2016), entre outros. Como resultado, sinalizamos que o índice de adesão dos docentes da amostra ao Programa de Formação Continuada da Univali vem aumentando, apesar de a carga horária mínima de formação exigida pela instituição ter diminuído ao longo dos anos. Identificamos que 100% dos docentes selecionados concentraram carga horária nas temáticas pedagógicas. A partir dos dados coletados pelo Programa de Avaliação Institucional, constatamos que a média atribuída pelos estudantes à atuação dos docentes integrantes da amostra varia entre 8,3 e 8,7. Dos 69 docentes selecionados, 95,66% possuem média superior a 7; três possuem média inferior a sete e nenhum docente possui média inferior a seis.

Published: May 2019

Muitas são as possibilidades para a promoção de inovações na formação inicial de professores, porém poucas ações efetivamente têm se concretizado na prática em sala de aula da Educação Básica. O objetivo deste trabalho é contribuir com a formação inicial de professores de Física, ao apresentar e discutir uma proposta pedagógica inovadora, na perspectiva do desenvolvimento profissional docente, no contexto do curso de Licenciatura em Física da Universidade Federal do Triângulo Mineiro (UFTM), Minas Gerais, Brasil. Trabalhou-se especificamente nas disciplinas obrigatórias “Instrumentação para o Ensino de Física” (IEF) e “Orientação e Estágio Curricular Supervisionado IV” (ECS IV). São socializados os trabalhos desenvolvidos em diferentes temas da Física, vinculando-os à tríade arte-ciência-cultura, em uma abordagem avaliativa não fragmentada e fomentada por ações interdisciplinares e contextualizadas, com a finalidade de maximizar a atuação do futuro professor da disciplina, com um viés de inovação curricular, em âmbito avaliativo e metodológico. Buscou-se a elaboração e aplicação de um objeto educacional como forma de avaliação das ações dos futuros professores, na intersecção entre as disciplinas de IEF e ECS IV, na qual as temáticas discutidas em IEF fomentaram a aplicação em sala de aula em ECS IV. Conjetura-se que as ações propostas foram concretizadas integralmente, proporcionando novas vivências aos licenciandos em relação aos conceitos trabalhados na Universidade e culminando em inovações de natureza metodológica, curricular e avaliativa em sala de aula da Educação Básica, por meio de novas roupagens para temas tradicionais da Física.
Ferramenta de iniciação à pesquisa: avaliação significativa na EAD
Authors: Wunsch Luana , Soares Ana Paula , Margevica Ieva
Published: May 2019

Quando se começa a falar de educação neste século XXI, parece já haver um discurso massificado sobre a relação entre tecnologia e conhecimento. Isto ocorre porque já é sabido que a sociedade mudou e que as mudanças dissimularam e dissimularão os inúmeros sistemas sociais, entre os quais a educação. Assim, falar de espaços educacionais é relatar sobre suas diversas roupagens para o momento atual. Neste sentido, a Internet, como um dos principais lugares de coleta de informações na atualidade, ganha a visibilidade de ponto de encontro para troca de experiências. E nesse cenário de propagação on line, é possível encontrar novas possibilidades metodológicas para melhorar o acesso, apresentando oportunidades de pesquisa e superação de desafios acadêmicos. Ao destacar o universo da Educação Superior, o presente artigo tem como objetivo identificar como se dá a avaliação da aprendizagem na modalidade a distância, na tentativa de dar linhas de orientação para que não seja mais um meio certificador de práticas tecnicistas. A partir da problemática sobre quais seriam as perspectivas de 713 graduandos, de Pedagogia, sobre suas ações acadêmicas, as quais até então estavam socialmente intrínsecas na possibilidade face-to-face, e por meio de uma das principais atividades de avaliação, o trabalho de conclusão de curso, a pesquisa apresenta a trajetória de uma investigação que teve como resultado o desenho de uma ferramenta on line adaptada às necessidades deste público de forma significativa.

Aim: The purpose of this pilot study was to quantify the effect of a continued active video games (AVG) playing on the tennis forehand and backhand technique development.

Methods: Altogether 24 tennis players (7 – 9 year olds) were randomly divided in two different groups, both involved in a 12-week tennis training program (twice a week for an hour). The participants in the experimental group received an additional twice a week (20-minute) AVG Virtua Tennis 4 game intervention at the end of each regular tennis training hour, while the participants in the control group received no additional intervention. Pre- and post-AVG intervention, the Tennis Rating Score for Children scale (TRSC) was applied to detect tennis training-related changes that occur in each specific stroke.

Results: Our results at the post-test show that participants in the experimental group did not significantly improved in one element (TRSC12; p = 0,317) in the forehand stroke and two (TRSC10; p = 0,157 and TRSC12 p = 0,157) in the backhand. The control group significantly improved in all the fifteen evaluated elements in both the forehand and backhand stroke. The experimental group had a higher effect size in all the kinetic chain section in both the forehand and backhand stroke compared to the control. The same happens for the TRSC7 (point of contact – height).

Conclusion: Prolonged AVG playing seems to improve visual attentions skills (perception of a moving object) in young tennis players, giving them the opportunity to be able to prepare themselves for the oncoming ball sooner as compared to their control counterparts. From the other perspective, AVG were shown to negatively affect correct players positioning, especially at the beginning and at the end of a stroke.

Published: May 2019

Background

Exit-site infection (ESI) and tunnel infection (TI) of the peritoneal dialysis (PD) catheter are significant causes of catheter or even method loss as well as patient morbidity. Among the methods that have been in use thus far, the removal and replacement of the catheter often needs to be followed by switching temporarily to hemodialysis, whereas catheter splicing or unroofing of the tunnel tract and shaving/removal of the superficial catheter cuff have not gained universal acceptance thus far.

Methods

We treat chronic ESI with exit-site relocation under local anesthetic with removal of the external cuff. For the purposes of this study, we conducted a retrospective cohort analysis of all exit-site relocations performed using that technique over a 5-year period.

Results

Twenty-seven patients (16 male, mean age 58 years, range 23 – 81 years) with chronic ESI underwent exit-site relocation under local anesthetic as a day-case procedure. Follow-up was 47.5 ± 22.4 months (range 10.8 – 79.4 months). No dialysate leaks occurred following the procedure. Peritoneal dialysis was resumed immediately. The procedure resulted in long-term resolution of the infection in 20 of the 27 patients (74%). In 7 patients (26%), the catheter had to be removed eventually, either because of ESI recurrence (5 patients) or TI (2 patients), which in 2 cases was subsequently complicated by PD peritonitis, and the patients were switched to hemodialysis.

Conclusion

The technique described herein is a safe, straightforward, and effective method for the treatment of chronic ESI while the patient remains on PD and avoids switching to hemodialysis.
Free Water Transport and its Association with Cardiovascular Status in Children on Peritoneal Dialysis

Published: May 2019

Background

Volume overload is one of the most important factors associated with left ventricular hypertrophy (LVH) and cardiovascular disease in chronic peritoneal dialysis (PD) patients. MiniPET is a reliable tool to evaluate free water transport (FWT). In a clinical setting, the significance of FWT has not been evaluated in terms of outcome in children on PD. The objective was to define a FWT value of clinical significance in children on PD, fixing its relationship to left ventricular mass index (LVMI) as a well-known outcome parameter.

Methods

MiniPET was performed with 3.86% glucose, 1-h long, to measure FWT in PD patients > 6 years old. An echocardiogram (ECG) was performed within 2 months of the MiniPET. Left ventricular hypertrophy was defined as LVMI ≥ 38.6 g/height2.7 (95th percentile). Receiver operating characteristic curve (ROC) analysis was used to determine the cut-off value of FWT searching the highest sensitivity and specificity to differentiate patients with normal/abnormal LVMI. A p < 0.05 was considered significant.

Results

Forty-six studies were performed on 32 patients, 16 males; mean age 11.59 ± 3.07 years. Mean normalized FWT (nFWT) was 144.4 ± 84.8 mL/m2, corresponding to 46.7% of total ultrafiltration. Mean LVMI was 42 ± 11.3 g/m2.7 with a negative correlation to nFWT ( p < 0.01). Eighteen out of 32 patients had LVH. The ROC analysis (nFWT vs LVMI) showed an area under the curve of 0.71 (95% confidence interval [CI], 0.53 – 0.89; p = 0.04), allowing a cut-off nFWT value of 110 mL/m2 to be defined, dividing the population into 2 groups of patients according to the LVMI cut-off value of 38,6 g/m2.7.

Conclusions

The nFWT showed an inverse correlation to LVMI. A nFWT value < 110 mL/m2 was significantly associated with LVH. The negative relationship observed between nFWT and LVMI, and the cut-off level for nFWT according to the 95th percentile of LVMI, suggest that the regular evaluation of nFWT could become a useful tool in assessing the capacity of PD treatment to keep patients’ volume status under control, avoiding cardiovascular impairment.

Published: May 2019

Background

Home dialysis therapies, including peritoneal dialysis (PD), are preferred treatment strategies, offering flexibility and improved wellbeing. However, patients with complex disease and comorbidity may require assistance with personal care and healthcare-related tasks. The study objective was to formally assess the type and frequency of PD assistance received by patients over 50, and the relationship to observed frailty, functional status, and cognitive ability at the time of PD therapy initiation.

Methods

Using a multicentered, prospective observational study design, patients aged ≥ 50 years were recruited from those starting PD. Patients underwent formal evaluation using validated components of a Comprehensive Geriatric Assessment. The receipt and nature of assistance with PD tasks were assessed 1 month after dialysis start by questionnaire.

Results

A total of 121 patients (age 69 ± 10 years, 67% male, 54% diabetic) were recruited. A total of 75 (62%) patients received assistance for a variety of tasks from friends or family ( n = 41, 34%) or a paid caregiver ( n = 34, 28%) 1 month after starting dialysis. At baseline, there was a high prevalence of functional dependency (79/120, 66%), frailty (71/110, 65%), and impaired cognition (68/115, 59%). Only 5% were fully independent, clinically robust, and scored within the normal range on cognitive testing. Factors associated with PD assistance included comorbidity ( p < 0.03), cognitive impairment ( p < 0.0001), and functional dependence ( p < 0.02).

Conclusion

Older patients initiating PD in the outpatient setting have high rates of frailty, functional dependence, and cognitive changes at the time they initiate dialysis. More research is required to better understand how those factors contribute to the use of PD assistance.

Background

The present study was to investigate the changes in outcomes of incident patients who started peritoneal dialysis (PD) between 2006 – 2010 and 2011 – 2015 in Southern China.

Methods

In this single-center cohort study, incident PD patients from January 1, 2006, to December 31, 2015, were enrolled. Collected data included baseline demographic, clinical, biochemical characteristics, and outcomes. Patients who initiated PD during 2006 – 2010 and 2011 – 2015 were followed up until December 31, 2011, and December 31, 2016, respectively. Peritonitis rate, patient survival, and technique survival were compared between the 2 incident cohorts.

Results

A total of 2,021 incident PD patients were enrolled, with a mean age of 47.2 ± 15.2 years, 40.6% female. Compared with the 2006 – 2010 cohort ( n = 1,073), patients initiating PD during 2011 – 2015 ( n = 948) were younger (46.2 ± 14.8 vs 48.1 ± 15.5 years, p = 0.006), had similar baseline estimate glomerular filtration rate (eGFR) (5.81 ± 2.41 vs 5.81 ± 2.89 mL/ min/1.73 m2, p = 0.109) and comparable percentage of diabetes mellitus (24.9% vs 25.7%, p = 0.682). The overall peritonitis rate in the 2011 – 2015 cohort was lower than in the 2006 – 2010 cohort (0.158 vs 0.161 episodes per year, p = 0.001). At the end of 1, 3, and 5 years, the 2006 – 2010 and 2011 – 2015 cohorts had patient survival rates of 94%, 82%, 64%, and 97%, 87%, 74%, respectively ( p < 0.001). After multivariable adjustment, patients starting PD in 2011 – 2015 were associated with lower risk of all-cause mortality (hazard ratio [HR] 0.77, 95% confidence interval [CI] 0.60 – 0.98). In gender and age-stratified models, male patients had a significantly lower risk of all-cause mortality (HR 0.58, 95% CI 0.41 – 0.83), and patients with age < 65 years showed a significantly lower risk of cardiovascular (CV) mortality (HR 0.63, 95% CI 0.40 – 0.99) in 2011 – 2015 compared with 2006 – 2010. The death-censored technique survival rates were not significantly different between the 2 cohorts ( p = 0.234).

Conclusion

Peritonitis rates and patient survival on PD continue to improve. Patients initiating PD between 2011 and 2015 were associated with better outcomes.
Mechanochemical synthesis of hyper-crosslinked polymers: influences on their pore structure and adsorption behaviour for organic vapors
Authors: Grätz Sven , Zink Sebastian , Kraffczyk Hanna , Rose Marcus , Borchardt Lars
Published: May 2019

This study elucidates a mechanochemical polymerization reaction towards a hyper-crosslinked polymer as an alternative to conventional solvent-based procedures. The swift and solvent-free Friedel–Crafts alkylation reaction yields a porous polymer with surface areas of up to 1720 m2g−1 and pore volumes of up to 1.55 cm3g−1. The application of LAG (liquid-assisted grinding) revealed a profound impact of the liquid´s boiling point on the textural properties of the obtained polymer materials. Finally, the materials are characterized by vapour sorption experiments with benzene and cyclohexane.
