Trigger performance of mid-level ICU mechanical ventilators during assisted ventilation: a bench study

Objective: To compare the triggering performance of mid-level ICU mechanical ventilators with a standard ICU mechanical ventilator. Design: Experimental bench study. Setting: The respiratory care laboratory of a university-affiliated teaching hospital. Subject: A computerized mechanical lung model, the IngMar ASL5000. Interventions: Ten mid-level ICU ventilators were compared to an ICU ventilator at two levels of lung model effort, three combinations of respiratory mechanics (normal, COPD and ARDS) and two modes of ventilation, volume and pressure assist/control. A total of 12 conditions were compared. Measurements and main results: Performance varied widely among ventilators. Mean inspiratory trigger time was < 100 ms for only half of the tested ventilators. The mean inspiratory delay time (time from initiation of the breath to return of airway pressure to baseline) was longer than that for the ICU ventilator for all tested ventilators except one. The pressure drop during triggering (Ptrig) was comparable with that of the ICU ventilator for only two ventilators. Expiratory Settling Time (time for pressure to return to baseline) had the greatest variability among ventilators. Conclusions: Triggering differences among these mid-level ICU ventilators and with the ICU ventilator were identified. Some of these ventilators had a much poorer triggering response with high inspiratory effort than the ICU ventilator. These ventilators do not perform as well as ICU ventilators in patients with high ventilatory demand.

Report from The International Society for Nomenclature of Paediatric and Congenital Heart Disease: cardiovascular catheterisation for congenital and paediatric cardiac disease (Part 1-Procedural nomenclature)

Interventional cardiology for paediatric and congenital cardiac disease is a relatively young and rapidly evolving field. As the profession begins to establish multi-institutional databases, a universal system of nomenclature is necessary for the field of interventional cardiology for paediatric and congenital cardiac disease. The purpose of this paper is to present the results of the efforts of The International Society for Nomenclature of Paediatric and Congenital Heart Disease to establish a system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease, focusing both on procedural nomenclature and on the nomenclature of complications associated with interventional cardiology. This system of nomenclature for cardiovascular catheterisation for congenital and paediatric cardiac disease is a component of The International Paediatric and Congenital Cardiac Code. This manuscript is the first part of a two-part series. Part 1 will cover the procedural nomenclature associated with interventional cardiology as treatment for paediatric and congenital cardiac disease. This procedural nomenclature of The International Paediatric and Congenital Cardiac Code will be used in the IMPACT Registry (TM) (IMproving Pediatric and Adult Congenital Treatment) of the National Cardiovascular Data Registry (R) of The American College of Cardiology. Part 2 will cover the nomenclature of complications associated with interventional cardiology as treatment for paediatric and congenital cardiac disease.

Sickness and Aggressive Behavior in Dominant and Subordinate Mice

Sick animals show a set of organized behavioral changes (sickness behavior), which is the result of a motivational re-organization of the behavior as a whole. Sickness behavior display can be influenced by the social context. In this work, we sought to investigate the regulation of sickness behavior within a pair of mice in the presence of an intruder mouse. Dominant and subordinate mice were treated with the bacterial endotoxin lipopolysaccharide (LPS) and were challenged with the presence of an intruder mouse. LPS effects depended on ranking and social context. Even though dominant mice displayed more agonistic interaction towards the intruder, subordinate mice displayed agonistic behavior towards the intruder when their dominant companion was treated with LPS. The results show that, not only sickness behavior is differentially expressed among different social ranks, but also that sickness behavior is related to different reactions among surrounding animals. These data are relevant for a biological approach to the relation between sickness behavior and social behavior.

Prevention of intraabdominal adhesions in Kasai portoenterostomy

An infant with biliary atresia had the right side of his liver covered with a sodium hyaluronate-based bioresorbable membrane during his initial Kasai portoenterostomy procedure. When his peritoneal cavity was entered 10.6 months (317 days) later for a liver transplant operation there was a remarkable absence of intraabdominal adhesions leading to a smooth operation and an uncomplicated recovery.

Behaviour rating scales for older people with dementia: which is the best for use by nurses?

There is increasing awareness of the importance of disruptive behaviour in people with dementia and the need for rating scales to accurately and reliably measure this behaviour. When rating scales are to be administered by nurses, scale characteristics must take into account the limitations of the nursing role and the nature of the environment in which nurses work. This paper reviews thirty-one rating scales that have been used to measure behaviour in dementia. From this analysis, five scales were identified as suitable for use by nurses when measuring disruptive behaviour in older people with dementia.

The effects of silica fillers on the gelation and vitrification of highly filled epoxy-amine thermosets

Highly filled thermosets are used in applications such as integrated circuit (IC) packaging. However, a detailed understanding of the effects of the fillers on the macroscopic cure properties is limited by the complex cure of such systems. This work systematically quantifies the effects of filler content on the kinetics, gelation and vitrification of a model silica-filled epoxy/amine system in order to begin to understand the role of the filler in IC packaging cure. At high cure temperatures (100 degreesC and above) there appears to be no effect of fillers on cure kinetics and gelation and vitrification times. However, a decrease in the gelation and vitrification times and increase the reaction rate is seen with increasing filler content at low cure temperatures (60-90 degreesC). An explanation for these results is given in terms of catalysation of the epoxy amine reaction by hydrogen donor species present on the silica surface and interfacial effects.

Behaviour of older people admitted for residential respite care

The aim of this pilot study was to determine whether residential respite care is used because of disruptive behaviour displayed by older people. The specific objectives were to 1) characterise older people being admitted for residential respite care, 2) obtain a preliminary estimate of the proportion of older people in residential respite care because of disruptive behaviour, and, 3) examine the relationship between residential respite care and disruptive behaviour. A quantitative approach using a cross-sectional survey was employed. The respite recipients were 35 older people with a mean age of 81.5 years (range 67-96 years). The respite recipients had been admitted for residential respite care to aged care hostels and nursing homes in a provincial city and its surrounding rural area. Nurses rated disruptive behaviour using the Dementia Behavior Disturbance Scale (DBDS). Additional reliability data for the DBDS are provided. The study found that the largest specific group of residential respite care users were widows (31.4%) who lived alone in their own home. The reason for over half (51.4%) of the residential respite admissions was to give a carer a 'break' from the older person. Although a large proportion (80%) of respite recipients were rated as having disruptive behaviour, the proportion of admissions because of disruptive behaviour was much less (28.6%). People with dementia (37.1%) scored significantly higher than people without dementia on the DBDS [F (1,33)=15.57, p

Uso de tecnologias de informa????o e comunica????o na gest??o p??blica: exemplos no governo federal

A administra????o p??blica passou por diversas mudan??as nos ??ltimos 30 anos. Parte dessas altera????es tem origem nas oportunidades criadas pelas inova????es tecnol??gicas. O objetivo deste trabalho ?? apresentar como tem sido o uso de tecnologias da informa????o e comunica????o (TICs) nas inova????es promovidas na administra????o p??blica federal brasileira. Para tanto, tomamos como base a descri????o de cinco experi??ncias inovadoras em TIC premiadas nos concursos anuais Inova????o na Gest??o P??blica Federal, realizados pela Escola Nacional de Administra????o P??blica (ENAP): o Portal da Transpar??ncia da Controladoria-Geral da Uni??o (CGU); o Programa Nacional do Livro Did??tico; o uso dos computadores de m??o pelo Instituto Brasileiro de Geografia e Estat??stica (IBGE); a entrega da Declara????o do Imposto de Renda via internet; e a utiliza????o de urnas eletr??nicas nas elei????es brasileiras. A despeito da relev??ncia dos avan??os do governo eletr??nico brasileiro at?? aqui, medidas de aprimoramento da intera????o entre os diversos ??rg??os p??blicos e tamb??m das pol??ticas p??blicas de inclus??o digital ainda se fazem necess??rias.

Gioconda Mussolini: uma travessia bibliográfica

Com este trabalho, dou continuidade à divulgação dos resultados de uma pesquisa voltada para a reconstrução da trajetória intelectual da professora Gioconda Mussolini, pioneira no ensino de antropologia na Faculdade de Filosofia da USP, entre 1944 e 1969. Nesta etapa, resenho a sua produção mais significativa: seis artigos e a co-autoria de um livro, textos dedicados a vários aspectos da vida cultural e social de populações de pescadores do litoral do estado de São Paulo, produzidos entre 1944 e 1961 e fruto de intensas e numerosas pesquisas de campo. O objetivo da análise é mostrar como o conjunto das atitudes metodológicas que se revelam na formulação dos textos remete para uma superação crítica dos "estudos de comunidade", no contexto dos quais Gioconda havia se formado, tanto como aluna da USP e da Escola Livre de Sociologia e Política quanto como colega e colaboradora de representantes dessa vertente (Donald Pierson, Emilio Willems e Egon Schaden, entre outros); e que, nesse sentido, ela se aproxima mais das perspectivas de outros colegas seus, como Antonio Candido e Florestan Fernandes. Finalmente, aponto os primeiros elementos que permitem ligar a sua produção aos rumos sucessivos do campo da etno-antropologia da pesca no Brasil.

Soldadura a frio de revestimentos vinílicos para pavimentos

As preocupações ambientais com o aproveitamento ou a reciclagem depois da vida útil de um material, o benefício que a utilização desse material pode trazer ao mundo, a forma como o produto é obtido, são assuntos em geral importantes nos dias que correm. No caso especifico desta tese, o material mais falado será o vinílico, servindo de mote para apresentar uma solução alternativa de soldadura de juntas para pavimentos vinílicos. Preocupações com as exigências e classificações funcionais, bases de assentamento, camadas de regularização/primários e colas serão também destacadas, até porque sem a boa execução/conjugação de todas as partes dificilmente obteríamos um bom pavimento. Cada vez mais, soluções alternativas para situações correntes são procuradas, quer por construtores quer por projectistas, tendo em vista o melhoramento não só dos trabalhos a realizar mas também o aspecto visual dos mesmos quando concluídos. Constitui objectivo essencial da presente tese provar que uma solução praticamente desconhecida no nosso país como é o caso da soldadura a frio, num pavimento vinílico, é tão boa ou melhor que a solução tradicional de soldadura a quente, onde o cordão de soldadura é visível. Países como a França ou a Alemanha, já utilizam há alguns anos esta solução, não só porque permite aos arquitectos projectar chãos em vinílico mais elaborados não sendo visível qualquer tipo de descontinuidade/junta, mas também porque em termos de execução e utilização permite uma maior rapidez.
