An Ethics Core Curriculum for Australasian Medical Schools

Teaching ethics incorporates teaching of knowledge as well as skills and attitudes. Each of these requires different teaching and assessment methods. A core curriculum of ethics knowledge must address both the foundations of ethics and specific ethical topics. Ethical skills teaching focuses on the development of ethical awareness, moral reasoning, communication and collaborative action skills. Attitudes that are important for medical students to develop include honesty, integrity and trustworthiness, empathy and compassion, respect, and responsibility, as well as critical self-appraisal and commitment to lifelong education.

Conductive hearing loss in preterm infants with bronchopulmonary dysplasia

Objective: To determine the risk of conductive hearing loss in preterm infants with bronchopulmonary dysplasia (BPD) and preterm controls. Methodology: The study population consisted of 78 infants with BPD of 26-33 weeks gestation and 78 controls of similar gestational age matched for broad-based birthweight categories. An auditory brainstem response (ABR) audiology was performed shortly before hospital discharge. Visual reinforcement orientation audiometry (VROA) and impedance audiometry were performed at 8-12 months corrected for prematurity. Infants with persistent audiological abnormalities were referred for evaluation to paediatric ENT surgeons. Results: Infants with BPD had a significantly higher rate of ABR abnormalities (BPD: 22%, controls: 9%; P = 0.028). On VROA and impedance audiometry, the infants with BPD also had a higher rate of persistent abnormalities. Following ENT assessment, 22.1% of infants with BPD and 7.7% of controls had persistent conductive dysfunction requiring myringotomy and grommet tube insertion (P = 0.03). Most of these infants had normal ABR audiometry at hospital discharge. Conclusions: Preterm infants with BPD are at high risk of persistent conductive hearing loss late in the first year of life compared to controls. An ABR audiology conducted at the time of hospital discharge does not predict accurately later conductive hearing problems. Infants with BPD should have routine audiological evaluation toward the end of the first year of life.

A systematic study of the microwave and thermal cure kinetics of the DGEBA/DDS and DGEBA/DDM epoxy-amine resin systems

The microwave and thermal cure processes for the epoxy-amine systems (epoxy resin diglycidyl ether of bisphenol A, DGEBA) with 4,4'-diaminodiphenyl sulphone (DDS) and 4,4'-diaminodiphenyl methane (DDM) have been investigated for 1:1 stoichiometries by using fiber-optic FT-NIR spectroscopy. The DGEBA used was in the form of Ciba-Geigy GY260 resin. The DDM system was studied at a single cure temperature of 373 K and a single stoichiometry of 20.94 wt% and the DDS system was studied at a stoichiometry of 24.9 wt% and a range of temperatures between 393 and 443 K. The best values of the kinetic rate parameters for the consumption of amines have been determined by a least squares curve fit to a model for epoxy/amine cure. The activation energies for the polymerization of the DGEBA/DDS system were determined for both cure processes and found to be 66 and 69 kJ mol(-1) for the microwave and thermal cure processes, respectively. No evidence was found for any specific effect of the microwave radiation on the rate parameters, and the systems were both found to be characterized by a negative substitution effect.

Combining the analyses of introgressive hybridisation and linkage mapping to investigate the genetic architecture of population divergence in the lake whitefish (Coregonus clupeaformis, Mitchill)

Adaptation and reproductive isolation, the engines of biological diversity, are still elusive when discussing the genetic bases of speciation. Namely, the number of genes and magnitude of selection acting positively or negatively on genomic traits implicated in speciation is contentious. Here, we describe the first steps of an ongoing research program aimed at understanding the genetic bases of population divergence and reproductive isolation in the lake whitefish (Coregonus clupeaformis). A preliminary linkage map originating from a hybrid cross between dwarf and normal ecotypes is presented, whereby some of the segregating AFLP markers were found to be conserved among natural populations. Maximum-likelihood was used to estimate hybrid indices from non-diagnostic markers at 998 AFLP loci. This allowed identification of the most likely candidate loci that have been under the influence of selection during the natural hybridisation of whitefish originating from different glacial races. As some of these loci could be identified on the linkage map, the possibility that selection of traits in natural populations may eventually be correlated to specific chromosomal regions was demonstrated. The future prospects and potential of these approaches to elucidate the genetic bases of adaptation and reproductive isolation among sympatric ecotypes of lake whitefish is discussed.

Nomenclature of the GLUT/SLC2A family of sugar/polyol transport facilitators

The recent identification of several additional members of the family of sugar transport facilitators (gene symbol SLC2A, protein symbol GLUT) has created a heterogeneous and, in part, confusing nomenclature. Therefore, this letter provides a summary of the family members and suggests a systematic nomenclature for SLC2A and GLUT symbols.

ABOUT PSYCHOLOGICAL VARIABLES IN APPLICATION SCORING MODELS

The purpose of this study is to investigate the contribution of psychological variables and scales suggested by Economic Psychology in predicting individuals’ default. Therefore, a sample of 555 individuals completed a self-completion questionnaire, which was composed of psychological variables and scales. By adopting the methodology of the logistic regression, the following psychological and behavioral characteristics were found associated with the group of individuals in default: a) negative dimensions related to money (suffering, inequality and conflict); b) high scores on the self-efficacy scale, probably indicating a greater degree of optimism and over-confidence; c) buyers classified as compulsive; d) individuals who consider it necessary to give gifts to children and friends on special dates, even though many people consider this a luxury; e) problems of self-control identified by individuals who drink an average of more than four glasses of alcoholic beverage a day.

Factores determinantes na adesão parental ao tratamento oclusivo em crianças amblíopes

Introdução - Estudos de investigação recentes apontam para o facto de que cerca de 1/3 dos olhos amblíopes não chegam à acuidade visual de 5/10 apesar da terapia oclusiva. Uma das razões apontadas é a não adesão ao tratamento. O objectivo do presente estudo é contribuir para a determinação do grau de influência dos factores psicossociais na adesão à terapia oclusiva por parte dos pais de crianças amblíopes e avaliar se existem diferenças significativas entre as recomendações do Ortoptista, a percepção parental dessas mesmas recomendações e o comportamento descrito. Metodologia - Foi efectuado um estudo quantitativo transversal, no qual participaram pais de crianças amblíopes (n=100), a realizar tratamento oclusivo num hospital público e numa clínica privada em Lisboa. Os pais responderam a um questionário baseado na Teoria da Motivação e Protecção (TMP) de Rogers, no qual foram analisadas variáveis parentais como a gravidade, vulnerabilidade, auto-eficácia, intenções de comportamento, eficácia da resposta e barreiras ao tratamento. Adicionalmente, foram analisadas as variáveis percepção parental do número de horas de oclusão e comportamento parental descrito. Resultados - Os resultados apontam para uma percentagem de 72% de adesão parental ao tratamento oclusivo e uma percentagem de 28% de não adesão. As variáveis intenções de comportamento (p=O,Ol 5) e eficácia da resposta (p=O,Ol 1) demonstraram ser significativas na predição da adesão parental ao tratamento oclusivo em crianças amblíopes (a=0,05). Foi detectada uma correlação positiva moderada (kappa=0, 536) entre o número de horas de oclusão recomendado pelo Ortoptista e a percepção parental dessas mesmas recomendações e uma correlação positiva forte (kappa=0,700) entre o número de horas de oclusão percepcionadas e o comportamento descrito. Conclusões - A prévia noção por parte dos pais de que o tratamento é uma mais-valia com consequências benéficas, provoca o desenvolvimento de uma resposta adaptativa de coping, neste caso de adesão ao tratamento oclusivo. A intenção positiva dos pais para realizar o tratamento e a prévia noção da sua eficácia na melhoria da acuidade visual da criança são preditivas da adesão por parte destes. Nesse sentido a probabilidade da adesão ao tratamento será maior se os pais associarem a adopção do comportamento recomendado à melhoria do estado de saúde das crianças, o que de facto foi demonstrado por esta investigação.

Lidar com o sofrimento em Fisioterapia: a experiência formativa na ESTSP-IPP

A comunicação e a relação terapêutica são reconhecidamente domínios de competência dos profissionais de saúde cujas funções impliquem o contacto com doentes (Corney, 2000; Grilo & Pedro, 2005; Pio Abreu, 1998). Além do seu papel determinante na adesão terapêutica, a qualidade da comunicação e da relação terapêutica estabelecida tem particular impacto no sofrimento da pessoa, tomado como constructo multidimensional (McIntyre, 2004). Tradicionalmente descurados na formação académica, estes temas tendem actualmente a ganhar expressão nos currículos, para o que contribuíram, no espaço europeu, as recomendações para a adequação a Bolonha (Lopes, 2004). Neste trabalho, descrevemos a metodologia de formação adoptada para estes domínios na licenciatura em Fisioterapia da ESTSP-IPP, a funcionar segundo o modelo pedagógico designado Problem-Based Learning (Walsh, 2005; Macedo, 2009). Além dos conhecimentos disseminados ao longo de toda a estrutura curricular, temas como a comunicação (Watzlawick, Bavelas & Jackson, 1967/1993), a escuta activa (Gordon & Edwards, 1997), a relação terapêutica (Rogers, 1957/1992, 1980, 1985), as competências e microcompetências/técnicas de atendimento e de observação (Ivey, 1983; Ivey & Downing, 1990; Ivey, Gluckstern & Ivey, 2006) ou as comunicações difíceis (Faulkner, Maguire & Regnard, 1994; Maguire, 2000) são alvo de formação mais intensiva ao longo de cerca de 16 semanas consecutivas do 1º ciclo de estudos, com recurso a diferentes tipologias de aula visando desenvolver, além dos conhecimentos, atitudes e habilidades nestes domínios.

Sleep, stress and compensatory behaviors in Australian nurses and midwives

OBJECTIVE: To describe sleep, stress and compensatory behaviors in nurses and midwives. METHODS: The study included 41 midwives and 21 nurses working in Australian hospitals between 2005 and 2009. Participation was voluntary. All participants recorded on a daily basis their work and sleep hours, levels of stress and exhaustion, caffeine intake and use of sleep aids for a month (1,736 days, 1,002 work shifts). RESULTS: Participants reported moderate to high levels of stress and exhaustion on 20-40% of work days; experienced sleep disruption on more than 50% of work days; struggled to remain awake on 27% of work days; and suffered extreme drowsiness or experienced a near accident while travelling home on 9% of workdays. Age, perceived sleep duration and work hours were significant predictors of caffeine intake. About 60% of participants reported using sleep aids (about 20% reported taking prescription medications and 44% of nurses and 9% of midwives reported alcohol use as a sleep aid at least once during the study). Stress and workdays were significant predictors of sedative use. Overall, 22% reported being indifferent or mildly dissatisfied with their job. CONCLUSIONS: Sleep problems, high levels of stress and exhaustion and low job satisfaction are prevalent among nurses and midwives. The use of alcohol and sleeping pills as sleep aids, and the use of caffeine to help maintain alertness is also common. Nurses and midwives may use caffeine to compensate for reduced sleep, especially on workdays, and sleeping pills to cope with their daily work-related stress.

Recent advances in vacum sciences and applications

Recent advances in vacuum sciences and applications are reviewed. Novel optical interferometer cavity devices enable pressure measurements with ppm accuracy. The innovative dynamic vacuum standard allows for pressure measurements with temporal resolution of 2 ms. Vacuum issues in the construction of huge ultra-high vacuum devices worldwide are reviewed. Recent advances in surface science and thin films include new phenomena observed in electron transport near solid surfaces as well as novel results on the properties of carbon nanomaterials. Precise techniques for surface and thin-film characterization have been applied in the conservation technology of cultural heritage objects and recent advances in the characterization of biointerfaces are presented. The combination of various vacuum and atmospheric-pressure techniques enables an insight into the complex phenomena of protein and other biomolecule conformations on solid surfaces. Studying these phenomena at solid-liquid interfaces is regarded as the main issue in the development of alternative techniques for drug delivery, tissue engineering and thus the development of innovative techniques for curing cancer and cardiovascular diseases. A review on recent advances in plasma medicine is presented as well as novel hypotheses on cell apoptosis upon treatment with gaseous plasma. Finally, recent advances in plasma nanoscience are illustrated with several examples and a roadmap for future activities is presented.
