Reforming the law of medical negligence: Solutions in search of a problem

The Commonwealth Government's Principles Based Review of the Law of Negligence recently recommended reforms aimed at limiting liability and damages arising from personal injury and death, in response to the growing perception that the current system of compensating personal injury had become financially unsustainable. Recent increases in medical liability and damages have eroded the confidence of doctors and their professional bodies, with fears of unprecedented desertion from and reduced recruitment into high risk areas, and one of the primary foci of the review concerned medical negligence. The article analyses proposals to redefine the principles necessary for the finding of negligence, against the terms of reference of the review. The article assumes that for the foreseeable future, Australia will persist with tort-based compensation for personal injury rather than developing a no-fault scheme. If the suggested changes to the fundamental principles of negligence are unlikely to reduce medical liability, greater attention might be given to the processes which come into play after the finding of negligence, where reform is more likely to benefit both plaintiffs and defendants.

Genomovar diversity amongst Burkholderia cepacia complex isolates from an Australian adult cystic fibrosis unit

In this study, a combination of recA-based PCR assays and 16S rDNA restriction fragment length polymorphism (RFLP) analysis was used to determine the genomovar diversity of clinical Burkholderia cepacia complex isolates. Twenty-eight isolates were prospectively collected from patients attending a large Australian adult cystic fibrosis (CF) unit, 22 isolates were referred from other Australian CF units and a further eight isolates originated from patients without CF. The 28 prospectively collected isolates were distributed amongst the following genomovars: Burkholderia cepacia genomovar I (28.6%), Burkholderia multivorans (21.4%), Burkholderia cepacia genomovar III (39.3%), Burkholderia vietnamiensis (3.6%) and Burkholderia ambifaria (7.1%). The results of this study highlight the usefulness of 16S rDNA RFLP typing for the identification of other Burkholderia spp. and non-fermenting gram-negative bacteria.

A global health problem caused by arsenic from natural sources

Arsenic is a carcinogen to both humans and animals. Arsenicals have been associated with cancers of the skin, lung, and bladder. Clinical manifestations of chronic arsenic poisoning include non-cancer end point of hyper- and hypo-pigmentation, keratosis, hypertension, cardiovascular diseases and diabetes. Epidemiological evidence indicates that arsenic concentration exceeding 50 mug l(-1) in the drinking water is not public health protective. The current WHO recommended guideline value for arsenic in drinking water is 10 mug l(-1), whereas many developing countries are still having a value of 50 mug 1(-1). It has been estimated that tens of millions of people are. at risk exposing to excessive levels of arsenic from both contaminated water and arsenic-bearing coal from natural sources. The global health implication and possible intervention strategies were also discussed in this review article. (C) 2003 Elsevier Ltd. All rights reserved.

Unraveling the barriers to reconceptualization of the problem in chronic pain: The actual and perceived ability of patients and health professionals to understand the neurophysiology

To identify why reconceptualization of the problem is difficult in chronic pain, this study aimed to evaluate whether (1) health professionals and patients can understand currently accurate information about the neurophysiology of pain and (2) health professionals accurately estimate the ability of patients to understand the neurophysiology of pain. Knowledge tests were completed by 276 patients with chronic pain and 288 professionals either before (untrained) or after (trained) education about the neurophysiology of pain. Professionals estimated typical patient performance on the test. Untrained participants performed poorly (mean +/- standard deviation, 55% +/- 19% and 29% +/- 12% for professionals and patients, respectively), compared to their trained counterparts (78% +/- 21% and 61% +/- 19%, respectively). The estimated patient score (46% +/- 18%) was less than the actual patient score (P < .005). The results suggest that professionals and patients can understand the neurophysiology of pain but professionals underestimate patients' ability to understand. The implications are that (1) a poor knowledge of currently accurate information about pain and (2) the underestimation of patients' ability to understand currently accurate information about pain represent barriers to reconceptualization of the problem in chronic pain within the clinical and lay arenas.

Programa Eurosocial II: plan anual de acci??n 2014

O presente Plano Anual de A????o (PAA 2014) inscreve-se em clara continuidade com os precedentes exerc??cios program??ticos do programa EUROsocial II. No entanto, na medida que se passou o equador e se entra na reta final do Programa, se realizou um grande esfor??o para concentrar a????es e se focar em pa??ses que apresentam menos riscos e maiores condi????es de viabilidade para o alcance dos resultados esperados. Neste sentido, no ano 2014 vai representar um ponto de inflex??o, no que culminar?? grande parte das a????es do Programa, documentar-se-?? uma boa parte dos resultados conseguidos, projetando para o ano 2015 linhas de trabalho mais intersetoriais e estrat??gicas. Por conseguinte tem-se um PAA mais simplificado e melhor estruturado (de 10 ??reas tem??ticas passou-se a 4 macro-??reas), com uma dimens??o regional mais potente que tem permitido elevar a dimens??o estrat??gica do programa, e com a????es mais interconectadas e coerentes que respondem melhor a uma vis??o unit??ria do Programa. Neste exerc??cio de programa????o tanto os s??cios operativos como os s??cios coordenadores t??m sabido conjugar melhor os dif??ceis equil??brios que deve manter o programa: orienta????o a demanda vs. gest??o para resultados; dimens??o regional vs. abordagem de problem??ticas a n??vel nacional; dimens??o estrat??gica vs. dimens??o operativa. Tamb??m se incorporou algumas das recomenda????es realizadas por parte da avalia????o de meio de percurso que se realizou no segundo semestre do 2013.

Gravitational waves : a 100-year tool applied to the dark energy problem

Recent observations from type Ia Supernovae and from cosmic microwave background (CMB) anisotropies have revealed that most of the matter of the Universe interacts in a repulsive manner, composing the so-called dark energy constituent of the Universe. Determining the properties of dark energy is one of the most important tasks of modern cosmology and this is the main motivation for this work. The analysis of cosmic gravitational waves (GW) represents, besides the CMB temperature and polarization anisotropies, an additional approach in the determination of parameters that may constrain the dark energy models and their consistence. In recent work, a generalized Chaplygin gas model was considered in a flat universe and the corresponding spectrum of gravitational waves was obtained. In the present work we have added a massless gas component to that model and the new spectrum has been compared to the previous one. The Chaplygin gas is also used to simulate a L-CDM model by means of a particular combination of parameters so that the Chaplygin gas and the L-CDM models can be easily distinguished in the theoretical scenarios here established. We find that the models are strongly degenerated in the range of frequencies studied. This degeneracy is in part expected since the models must converge to each other when some particular combinations of parameters are considered.

O Plano de Ações Articuladas (PAR) como instrumento de organização do Sistema Nacional de Educação: estudo de caso dos municípios de Cariacica e de Vitória/ES

O objeto de estudo da presente pesquisa é a análise do Plano de Ações Articuladas (PAR), criado pelo Governo Federal por meio do Plano de Metas Compromisso Todos pela Educação (Decreto n. 6.094/2007), e suas possibilidades como instrumento de organização do Sistema Nacional de Educação. A pesquisa tem como objetivo geral analisar o processo de implantação/implementação do PAR em dois municípios do Espírito Santo (Cariacica e Vitória), com o intuito de entender como se deu o planejamento do PAR em nível nacional e em nível municipal; analisar como foi elaborado, como está sendo executado e quais as principais ações do PAR desenvolvidas nos municípios pesquisados, identificando as articulações existentes entre os municípios, estados e União. O argumento central é que o PAR é um instrumento de planejamento central, mas cuja execução necessita de ações descentralizadas. Parte-se da hipótese de que a organização dos municípios, do ponto de vista econômico e político, tem implicações na execução de um planejamento educacional mesmo que ele tenha um mesmo formato e padrão para todo o país. Ou seja, as características políticas, econômicas e culturais dos municípios configuram diferentes realidades na execução das políticas educacionais, o que traz uma desigualdade na oferta da qualidade do serviço educacional entre os entes federativos. A pesquisa realizada é de caráter qualitativo do tipo estudo de caso, particularmente o estudo de multicascos que, segundo Triviños (1987), propicia ao pesquisador estudar dois ou mais sujeitos ou organizações sem a necessidade de limitar-se a fatores de natureza comparativa. Como problema de pesquisa, portanto, é levantada a seguinte pergunta: é possível o PAR, com sua característica de centralização/descentralização, contribuir para a organização do Sistema Nacional de Educação? A pesquisa mostrou que a implementação de uma política de educação, como o PAR, envolve a capacidade técnica, organizacional e aspectos institucionais dos municípios. Nesse sentido para a consolidação do Sistema Nacional de Educação é necessário que o PAR não seja apenas uma política de captação de recursos, mas que os municípios tenham um plano norteador como catalizador de uma política de Estado.

Brazil: an emerging military power? The problem of the use of force in Brazilian international relations in the 21st century

The central goal of this paper is thinking about the Brazilian military power and its linking to the international ambitions of the country in the 21st century. After a comparative analysis to other BRICs and with a historical one about Brazil's strategic irrelevance, we aim to establish what the minimum military capacity Brazil would need in order to meet the country's latest international interests. Similarly, it will be discussed if the National Strategy of Defense, approved in 2008, and the recent strategic agreements signed with France represent one more step toward this minimum military capacity.

A model for the evaluation of data quality in health unit website

This article presents a research work, the goal of which was to achieve a model for the evaluation of data quality in institutional websites of health units in a broad and balanced way. We have carried out a literature review of the available approaches for the evaluation of website content quality, in order to identify the most recurrent dimensions and the attributes, and we have also carried out a Delphi method process with experts in order to reach an adequate set of attributes and their respective weights for the measurement of content quality. The results obtained revealed a high level of consensus among the experts who participated in the Delphi process. On the other hand, the different statistical analysis and techniques implemented are robust and attach confidence to our results and consequent model obtained.

On the Problem of Balancing the DC Capacitor Voltage Divider in Back-to-Back Multilevel Converters

This paper presents a new generalized solution for DC bus capacitors voltage balancing in back-to-back m level diode-clamped multilevel converters connecting AC networks. The solution is based on the DC bus average power flow and exploits the switching configuration redundancies. The proposed balancing solution is particularized for the back-to-back multilevel structure with m=5 levels. This back-to-back converter is studied working with bidirectional power flow, connecting an induction machine to the power grid.

Risk assessment of exposure to multiple mycotoxins in food

Moulds may produce a diversity of toxins such as aflatoxins, ochratoxins, trichothecenes, zearalenone, fumonisins and others. Although toxicological, environmental and epidemiological studies have addressed the problem of these toxins one by one, more than one mycotoxin are found usually in the same contaminated food. Risk assessment for humans potentially exposed to multimycotoxins suffers very much from the lack of adequate food consumption data. Furthermore, for a given mycotoxin, synergism and antagonism with other mycotoxins, found in the same food commodities, are not taken into account. Aflatoxin B1 and ochratoxin A belong to the most frequently occurring mycotoxins. This has repeatedly been demonstrated, however, normally, the risk resulting from their simultaneous occurrence is not considered. A descriptive study was developed to monitor air fungal contamination in one hospital food unit.

Formaldehyde in indoor air: a public health problem?

Formaldehyde was the first air pollutant, which already in the 1970s emerged as a specifically non-industrial indoor air quality problem. Yet formaldehyde remained an indoor air quality issue and the formaldehyde level in residential indoor air is among the highest of any indoor air contaminant. Formaldehyde concentrations in 4 different indoor settings (schools, office buildings, new dwellings and occupied dwellings) in Portugal were measured using Photo Ionization Detection (PID) equipment (11,7 eV lamps). All the settings presented results higher than the reference value proposed by Portuguese legislation. Furthermore, occupied dwellings showed 3 units with results above the reference. We could conclude that formaldehyde presence is a reality in monitored indoor settings. Concentration levels are higher than the Portuguese reference value for indoor settings and these can indicate health problems for occupants.
