When we eat, which bacteria should we be feeding?

Diet therapy utilizing probiotics and prebiotics may help treat many common gastrointestinal complaints. From birth to about 2 years of age the human digestive tract changes from sterile to a complex ecosystem with at least 500 bacterial species, most of these are benign and even necessary, however, pathogenic species also colonize the digestive tract. The idea is that prebiotics and probiotics can be used to displace and neutralise these pathogens.

Autobiographical memory and the self in a case of transient epileptic amnesia

Transient epileptic amnesia (TEA) is characterized by deficits in autobiographical memory (AM). One of the functions of AM is to maintain the self, suggesting that the self may undergo changes as a result of memory loss in temporal lobe epilepsy. To examine this, we used a modification of a task used to assess the relationship between self and memory (the IAM task) in a single case, E.B. Despite complaints of AM loss, E.B. had no difficulty in producing a range of self-images (e.g., I am a husband) and collections of self-defining AMs in support of these statements. E.B. produced fewer episodic memories at times of self-formation, but this did not seem to impact on the maintenance of self. The results support recent work suggesting the self may be maintained in the absence of episodic memory. The application of tasks such as that used here will further elucidate AM impairment in temporal lobe epilepsy. (C) 2011 Elsevier Inc. All rights reserved.

'They Shall Speak the Arabic Language and Take Pride in it': reconsidering the fate of Coptic after the Arab Conquest

The complaints on the adoption of Arabic by the Copts that are voiced by the Apocalypse of Pseudo-Samuel have often been quoted as the expiring words of the dying Coptic language. This article seeks to show that they are not to be taken so literally, and that they should rather be inserted in the context of a rift within the medieval Coptic church over the question of language choice, and beyond this, over that of accommodation with the Muslims. The use of Arabic by the episcopal church of Miṣr and by some prominent figures around it, which was linked to their proximity to the Fatimid court, was resented and denounced by more traditional circles, centred on the Patriarchate and on some important monasteries such as the one at Qalamūn where the Apocalypse was written. The suggestion is also made that the text is contemporary with the beginning of Coptic literary production in Arabic and with the introduction of Egyptian Christians at the caliphal court, namely in the last quarter of the tenth century, at the time of Severus ibn al-Muqqafa‘.

Culture, compassion and clinical neglect: probity in the NHS after Mid Staffordshire

Speaking of the public response to the deaths of children at the Bristol Royal Infirmary before 2001, the BMJ commented that the NHS would be 'all changed, changed utterly'. Today, two inquiries into the Mid Staffordshire Foundation Trust suggest nothing changed at all. Many patients died as a result of their care and the stories of indifference and neglect there are harrowing. Yet Bristol and Mid Staffordshire are not isolated reports. In 2011, the Health Services Ombudsman reported on the care of elderly and frail patients in the NHS and found a failure to recognise their humanity and individuality and to respond to them with sensitivity, compassion and professionalism. Likewise, the Care Quality Commission and Healthcare Commission received complaints from patients and relatives about the quality of nursing care. These included patients not being fed, patients left in soiled bedding, poor hygiene practices, and general disregard for privacy and dignity. Why is there such tolerance of poor clinical standards? We need a better understanding of the circumstances that can lead to these outcomes and how best to respond to them. We discuss the findings of these and other reports and consider whether attention should be devoted to managing individual behaviour, or focus on the systemic influences which predispose hospital staff to behave in this way. Lastly, we consider whether we should look further afield to cognitive psychology to better understand how clinicians and managers make decisions?

Procalcitonin is useful in identifying bacteraemia among children with pneumonia

Empirical antibiotic use is prescribed in managing children with pneumonia worldwide. We assessed the usefulness of procalcitonin (PCT) and interferon-alpha (IFN-alpha) in differentiating viral from bacterial pneumonia. Among 159 hospitalized children, pneumonia was diagnosed based on clinical complaints plus pulmonary infiltrate. Aetiology was investigated for 9 viruses and 4 atypical and 3 typical bacteria. PCT and IFN-alpha were measured in the serum sample collected on admission. Eight patients had bacteraemic infections, 38 had non-bacteraemic typical infections, and 19 patients had atypical bacterial infections. Viral and unknown aetiology was established in 57 (36%) and 34 (21%) cases, respectively. Three patients with bacterial infection without collected blood culture were excluded. IFN-alpha (IU/ml) was detectable in 20 (13%) cases. The difference among median PCT values of the bacteraemic (4.22; 1.56-7.56), non-bacteraemic typical bacterial (1.47; 0.24-4.07), atypical bacterial (0.18; 0.06-1.03) and only viral (0.65; 0.11-2.22) subgroups was significant (p = 0.02). PCT was >= 2 ng/ml in 52 (33%) cases. The presence of IFN-alpha was associated with PCT <2 ng/ml (90% vs. 64%, p = 0.02). The negative predictive value (95% confidence interval) of PCT >= 2 ng/ml was 95% (89-100%), 89% (78-100%), 93% (85-100%) for differentiation of bacteraemic from viral, atypical bacterial and non-bacteraemic typical bacterial infection, respectively, and 58% (49-68%) for differentiation between bacterial and viral infection. PCT may be useful in identifying bacteraemia among children hospitalized with community-acquired pneumonia. IFN-alpha was uncommonly detected.

Working at night and work ability among nursing personnel: when precarious employment makes the difference

To test the association between night work and work ability, and verify whether the type of contractual employment has any influence over this association. Permanent workers (N = 642) and workers with precarious jobs (temporary contract or outsourced; N = 552) were interviewed and filled out questionnaires concerning work hours and work ability index. They were classified into: never worked at night, ex-night workers, currently working up to five nights, and currently working at least six nights/2-week span. After adjusting for socio-demography and work variables, current night work was significantly associated with inadequate WAI (vs. day work with no experience in night work) only for precarious workers (OR 2.00, CI 1.01-3.95 and OR 1.85, CI 1.09-3.13 for those working up to five nights and those working at least six nights in 2 weeks, respectively). Unequal opportunities at work and little experience in night work among precarious workers may explain their higher susceptibility to night work.

The Prospective and Retrospective Memory Questionnaire: A population-based random sampling study

The Prospective and Retrospective Memory Questionnaire (PRMQ) has been shown to have acceptable reliability and factorial, predictive, and concurrent validity. However, the PRMQ has never been administered to a probability sample survey representative of all ages in adulthood, nor have previous studies controlled for factors that are known to influence metamemory, such as affective status. Here, the PRMQ was applied in a survey adopting a probabilistic three-stage cluster sample representative of the population of Sao Paulo, Brazil, according to gender, age (20-80 years), and economic status (n=1042). After excluding participants who had conditions that impair memory (depression, anxiety, used psychotropics, and/or had neurological/psychiatric disorders), in the remaining 664 individuals we (a) used confirmatory factor analyses to test competing models of the latent structure of the PRMQ, and (b) studied effects of gender, age, schooling, and economic status on prospective and retrospective memory complaints. The model with the best fit confirmed the same tripartite structure (general memory factor and two orthogonal prospective and retrospective memory factors) previously reported. Women complained more of general memory slips, especially those in the first 5 years after menopause, and there were more complaints of prospective than retrospective memory, except in participants with lower family income.

Implementation and role of device management Solutions to the end users

This research is based on consumer complaints with respect to recently purchased consumer electronics. This research document will investigate the instances of development and device management as a tool used to aid consumer and manage consumer’s mobile products in order to resolve issues in or before the consumers is aware one exists. The problem at the present time is that mobile devices are becoming very advanced pieces of technology, and not all manufacturers and network providers have kept up the support element of End users. As such, the subject of the research is to investigate how device management could possibly be used as a method to promote research and development of mobile devices, and provide a better experience for the consumer. The wireless world is becoming increasingly complex as revenue opportunities are driven by new and innovative data services. We can no longer expect the customer to have the knowledge or ability to configure their own device. Device Management platforms can address the challenges of device configuration and support through new enabling technologies. Leveraging these technologies will allow a network operator to reduce the cost of subscriber ownership, drive increased ARPU (Average Revenue per User) by removing barriers to adoption, reduce churn by improving the customer experience and increase customer loyalty. DM technologies provide a flexible and powerful management method but are managing the same device features that have historically been configured manually through call centers or by the end user making changes directly on the device. For this reason DM technologies must be treated as part of a wider support solution. The traditional requirement for discovery, fault finding, troubleshooting and diagnosis are still as relevant with DM as they are in the current human support environment yet the current generation of solutions do little to address this problem. In the deployment of an effective Device Management solution the network operator must consider the integration of the DM platform, interfacing with many areas of the business, supported by knowledge of the relationship between devices, applications, solutions and services maintained on an ongoing basis. Complementing the DM solution with published device information, setup guides, training material and web based tools will ensure the quality of the customer experience, ensuring that problems are completely resolved, driving data usage by focusing customer education on the use of the wireless service In this way device management becomes a tool used both internally within the network or device vendor and by the customer themselves, with each user empowered to effectively manage the device without any prior knowledge or experience, confident that changes they apply will be relevant, accurate, stable and compatible. The value offered by an effective DM solution with an expert knowledge service will become a significant differentiator for the network operator in an ever competitive wireless market. This research document is intended to highlight some of the issues the industry faces as device management technologies become more prevalent, and offers some potential solutions to simplify the increasingly complex task of managing devices on the network, where device management can be used as a tool to aid customer relations and manage customer’s mobile products in order to resolve issues before the user is aware one exists. The research is broken down into the following, Customer Relationship Management, Device management, the role of knowledge with the DM, Companies that have successfully implemented device management, and the future of device management and CRM. And it also consists of questionnaires aimed at technical support agents and mobile device users. Interview was carried out with CRM managers within support centre to further the evidence gathered. To conclude, the document is to consider the advantages and disadvantages of device management and attempt to determine the influence it will have over customer support centre, and what methods could be used to implement it.

Emergency department triage scales and their components : a systematic review of the scientific evidence

Emergency department (ED) triage is used to identify patients' level of urgency and treat them based on their triage level. The global advancement of triage scales in the past two decades has generated considerable research on the validity and reliability of these scales. This systematic review aims to investigate the scientific evidence for published ED triage scales. The following questions are addressed: 1. Does assessment of individual vital signs or chief complaints affect mortality during the hospital stay or within 30 days after arrival at the ED? 2. What is the level of agreement between clinicians' triage decisions compared to each other or to a gold standard for each scale (reliability)? 3. How valid is each triage scale in predicting hospitalization and hospital mortality? A systematic search of the international literature published from 1966 through March 31, 2009 explored the British Nursing Index, Business Source Premier, CINAHL, Cochrane Library, EMBASE, and PubMed. Inclusion was limited to controlled studies of adult patients (≥15 years) visiting EDs for somatic reasons. Outcome variables were death in ED or hospital and need for hospitalization (validity). Methodological quality and clinical relevance of each study were rated as high, medium, or low. The results from the studies that met the inclusion criteria and quality standards were synthesized applying the internationally developed GRADE system. Each conclusion was then assessed as having strong, moderately strong, limited, or insufficient scientific evidence. If studies were not available, this was also noted. We found ED triage scales to be supported, at best, by limited and often insufficient evidence. The ability of the individual vital signs included in the different scales to predict outcome is seldom, if at all, studied in the ED setting. The scientific evidence to assess interrater agreement (reliability) was limited for one triage scale and insufficient or lacking for all other scales. Two of the scales yielded limited scientific evidence, and one scale yielded insufficient evidence, on which to assess the risk of early death or hospitalization in patients assigned to the two lowest triage levels on a 5-level scale (validity).

Transtornos de aprendizagem : aspectos neuropsicossociais de uma população encaminhada à Secretaria Municipal da Saúde da cidade de São Leopoldo

Foram estudados 125 pacientes em idade escolar que procuraram o Posto de Atendimento Médico Especializado (PAME) da cidade de São Leopoldo, Rio Grande do Sul, Brasil, nos anos de 2003 e 2004, encaminhados pela escola, pelo pediatra ou Conselho Tutelar, por estarem apresentando dificuldades na escolarização. Realizaram-se entrevistas com os pais ou responsáveis, exame neurológico tradicional, exame neurológico evolutivo, eletroencefalograma em sono e vigília em todas as crianças e tomografia cerebral e ressonância magnética, quando necessário. Foram estudados aspectos neuropsicossociais dos indivíduos e de suas respectivas famílias. Encontraram-se famílias comprometidas em sua história prévia e atual: 29,30% com dificuldades escolares, 27,20% com doenças psiquiátricas, 26,10% com epilepsia, 21,70% com alcoolismo e 10,90% com deficiência mental. As comorbidades tiveram um papel relevante no desempenho escolar: 50,50% com hiperatividade, 17,20% com distúrbio de conduta e 17,20% com problemas emocionais (listados como queixa principal por ocasião do encaminhamento para a triagem).

Relations between regulation, competition policy and consumer protection in telecommunications, electricity and water supply

The purpose of this article is to discuss the relations between regulation, competition policy and consumer protection these relations in three key sectors of Brazil’s infrastructure: telecommunications, electricity and water supply. A study of the literature points to two general principles. First, the need for consumer protection depends on the “degree of sovereignty” enjoyed by consumers, defined in terms of the cost of consumer organization, consumers’ ability to evaluate services, and the level of competition in each sector. Second, the less sovereignty consumers enjoy the more consumer protection institutions are involved with regulation agencies. The evidence for the Brazilian case apparently corroborates these points. In addition, it is important to stress that consumer complaints in regulated sectors seem to have increased more intensely than in others. The article is divided into three sections. Section 1 presents theoretical elements and aspects of the relations between regulation, competition policy and consumer protection evidenced by international experience. Section 2 analyzes the Brazilian experience and in particular the available statistics on consumer complaints about telecommunications, electricity and water supply, submitted to Fundação Procon-SP during the nineties. The last section points to possible configurations of the institutional relations between competition policy, regulation and consumer protection, showing how the existing configuration of these areas in the three infrastructure sectors discussed confirms that the theoretical framework proposed has reasonable predictive power.

A articulação entre regulação, defesa da concorrência e proteção do consumidor nos setores de telecomunicações, energia elétrica e saneamento básico

O objetivo deste relatório é estudar a relação entre proteção ao consumidor, regulação e defesa da concorrência em três setores de infra-estrutura no Brasil: telecomunicações, energia elétrica e saneamento básico. A Seção I deste relatório apresenta uma descrição sintética dos três segmentos selecionados. A Seção II discute aspectos teóricos da relação entre proteção ao consumidor, de um lado, e regulação e defesa da concorrência, de outro, a partir da experiência brasileira e internacional. A Seção III apresenta a experiência brasileira de regulação dos três setores. A Seção IV apresenta algumas estatísticas recentes de reclamações dos consumidores, ainda não suficientemente exploradas pela pesquisa acadêmica. A Seção V discute possíveis configurações institucionais entre proteção ao consumidor, regulação e defesa da concorrência, sugerindo uma explicação para a configuração atual dessas áreas nos três segmentos de infra-estrutura selecionados.

Validação da termografia no diagnóstico de lesões por esforços repetitivos/distúrbios osteomusculares relacionados ao trabalho

As Lesões por Esforços Repetitivos e Doenças Osteomusculares Relacionadas ao Trabalho estão caracterizadas por queixas de grande incapacidade funcional, causadas pelo uso dos membros superiores em tarefas que envolvam movimentos repetitivos. Esses distúrbios também podem ocorrer nas atividades de lazer ou no cotidiano das pessoas, especialmente quando realizadas por períodos longos, sem pausas adequadas para recuperação muscular, ou ainda, sem devido acompanhamento médico. A avaliação de doenças ocupacionais é eminentemente clínica. São raros os casos em que os exames complementares apóiam o diagnóstico médico. Diante disso, o objetivo desta pesquisa foi verificar a eficácia da técnica de Termografia no diagnóstico de LER/DORT. A amostra (n=51) foi dividida em dois grupos. Um grupo experimental (n=41) composto por 26 Taquigrafas da Assembléia Legislativa do Rio Grande do Sul e 15 digitadores da Companhia Estadual de Energia Elétrica do Rio Grande do Sul e um grupo controle (n=10) composto por participantes com outras profissões. Todos eles estavam de acordo com o que prescreve a resolução 196/96 do Conselho Nacional de Saúde. Os resultados do teste Q de Cochran mostraram diferenças estatisticamente significativas entre os 3 observadores da Termografia nas regiões dos punhos, cotovelos e ombros para o teste. Os coeficientes de concordância Kappa de cada observador no teste e reteste foram elevados. O coeficiente de concordância Kappa entre os observadores no teste mostraram que os 3 observadores estavam seguros para diagnosticar punho direito e cotovelos. Tais resultados mostram que a Termografia foi mais sensível e específica que a Ecografia e o Exame Clínico nos punhos direito e esquerdo. Assim, podemos inferir que os dados obtidos através das imagens termográficas permitiram uma melhor visualização das áreas traumatizadas nos componentes da amostra.

Confiança valor e qualidade do produto como antecedentes da satisfação: um estudo empírico no mercado imobiliário

O conceito de confiança tem sido introduzido em estudos empíricos sobre marketing no Brasil partir do referencial teórico adotado principalmente nos Estados Unidos Europa. presente dissertação examina confiança, tanto no vendedor como na empresa, valor qualidade do produto percebidos pelos clientes como fatores que afetam satisfação em compras de valor, tal como compra de um imóvel residencial na planta. estudo se baseia nos artigos de Santos (2001), sobre o impacto do gerenciamento de reclamações sobre confiança lealdade do consumidor, de Doney Cannon (1997) sobre confiança no relacionamento entre empresas seus vendedores. estudo empírico trata de um levantamento de corte transversal, no qual foram testadas hipóteses específicas para examinar as relações entre as variáveis, em um processo de pesquisa formal estruturado, com uma amostra de 270 clientes. Os dados foram coletados partir da base de clientes de duas empresas brasileiras fortes nos segmentos em que atuam, uma corretora de imóveis outra incorporadora/construtora, ambas sediadas na cidade de São Paulo. análise dos dados foi feita com base no Modelo de Equações Estruturais (SEM), através do software Lisrel 8. Os resultados indicam que há confiança no corretor que está realizando venda do imóvel, sendo que satisfação com corretor influencia esta confiança. No entanto, experiências anteriores com corretores de imóveis características do corretor que realizou venda não têm impacto sobre confiança no corretor. Detectou-se também, que valor do produto confiança na construtora percebidos pelo cliente têm influencia sobre satisfação com compra, mas não qualidade percebida. Este estudo dá subsídios futuras pesquisas sobre confiança em compras de valor. São discutidas as limitações da pesquisa as implicações de seus resultados para gestão de marketing no Brasil.

Associação entre hipoestesia corneana, olho seco e outros fatores em portadores de diabetes melito tipo 2

Portadores de diabetes parecem ter mais queixas de olho seco do que o resto da população. Acredita-se que isto possa estar associado a uma forma de neuropatia diabética expressa por uma redução na sensibilidade corneana desses pacientes. Nossos principais objetivos neste estudo foram avaliar a influência da diabetes melito tipo 2 na sensibilidade corneana central e verificar se há uma associação entre a sensibilidade corneana central e a síndrome do olho seco em indivíduos com a doença. Assim, 62 portadores de diabetes tipo 2 foram submetidos a um exame oftalmológico de rotina, a uma ceratoestesiometria e a testes específicos para avaliar olho seco e polineuropatia distal simétrica. Num outro grupo, 20 voluntários saudáveis tiveram seus olhos avaliados da mesma forma, exceto pela não realização dos testes específicos para disfunção lacrimal. Entre os indivíduos diabéticos avaliados, foram observados 53.2% com hipoestesia corneana, 54.2% com retinopatia diabética, 45.9% com polineuropatia distal simétrica e 51.6% com a síndrome do olho seco. Entre os principais achados, observamos associações significativas envolvendo: diabetes tipo 2 e hipoestesia corneana central, síndrome do olho seco e hipoestesia corneana central, produção lacrimal reflexa (avaliada pelo teste de Schirmer II) e sensibilidade corneana central e retinopatia diabética proliferativa e sensibilidade corneana central. Uma possível associação foi encontrada envolvendo síndrome do olho seco retinopatia diabética proliferativa. Os autores discutem os resultados obtidos e os mecanismos envolvidos.
