White piedra: molecular identification of Trichosporon inkin in members of the same family

INTRODUCTION: White piedra is a superficial mycosis caused by the genus Trichosporon and characterized by nodules on hair shaft. METHODS: The authors report a family referred to as pediculosis. Mycological culture on Mycosel® plus molecular identification was performed to precisely identify the etiology. RESULTS: A Trichosporon spp. infection was revealed. The molecular procedure identified the agent as Trichosporon inkin. CONCLUSIONS: White piedra and infection caused by T. inkin are rarely reported in Southern Brazil. The molecular tools are essentials on identifying the Trichosporon species.

Surveillance of influenza A H1N1 2009 among school children during 2009 and 2010 in São Paulo, Brazil

INTRODUCTION: Influenza A H1N1 2009 is associated with a high morbidity rate among children around the world, including Brazil. This survey was conducted on samples of symptomatic children (< 12 years) to investigate the influenza virus as the etiological agent of respiratory infections in a day care school in a health facility during the first and second pandemic wave of H1N1 (2009-2010) in São Paulo, Brazil. METHODS: Influenza infections were determined by real-time PCR in 34% (47/137) of children with a median age of 5 years (8 months - 12 years), from June to October 2009 and in 16% (14/85) of those with median age of 6 years (1-12 years), from March to November 2010. RESULTS: In general, most positive cases (64%) occurred in children aged 5-12 years, this age group was significantly the most affected (39.8%, p = 0.001, OR = 8.3, CI 95% 1.9-36.9). Wheezing was reported by 31% (19/61) and dyspnea by 23% (14/61) of the studied patients. An outbreak of influenza H1N1 with an attack rate of 35.7% among children (median age 6 years) was documented in April 2010, before the vaccination campaign against the pandemic virus was extended for children up to 5 years in Brazil. CONCLUSIONS: Therefore, the study reinforces the recommendation to immunize school children to reduce the incidence of the disease.

Board independence and innovation

Legislation introduced in the U.S. in 2002/2003 significantly changed board composition of public firms by imposing a 50% independent directors’ ratio. Research on the effect of independent directors is not consensual, implying that this exogenous shock is a unique opportunity to study their importance. This study answers the question of whether or not independent directors can effectively mitigate agency conflicts between shareholders and the management, having a positive impact on the choice of successful R&D projects. We find that an increase of board independence has a positive impact on patent counts. Hence, the results support that independent directors truly spur innovation and risk taking.

Almirante: Evaluating the board game: Board game, startup, discounted cash flow, venture capital method, real options

This thesis evaluates a start-up company (Jogos Almirante Lda) whose single asset is a board game named Almirante. It aims to conclude whether it makes sense to create a company or just earn copyrights. The thesis analyzes the board game’s market, as part of the general toy’s market, from which some data exists: European countries as well as the USA. In this work it is analyzed the several ways to finance a start-up company and then present an overview of the valuation of the Jogos Almirante based on three different methods: Discounted Cash Flow, Venture Capital Method and Real Options.

Comparateive analysis: Public and private school management systems

The Portuguese educational system has counted, for many years, with the co-existence of both public and private schools. In fact, the country’s growth and development led, in the past, to an increasing demand for free of charge public education that could only be matched through the creation of “publicly-subsidized and privately owned and managed schools”. Still, the demographic evolution of Portugal recently generated a decrease on the demand for public educational services. This situation has raised doubts about the true contribution of this type of school for the public education system. This paper aims at answering this question by isolating the impact of different property and management schemes on the performance of students, resorting to cross-section data on 9th grade students from 2010. The results corroborate the well known result on the relevance of the family socio-economic background for students’ performance, but do also sustain the existence of a significant positive impact of private ownership and management schemes on the overall performance of students. These results suggest that there might be gains associated with the expansion of such schemes within the public education system.

Appreciating the power of words and imaginative organizing: A triadic model of ethics practiced in everyday conversations

This thesis provides an alternative framework to analyze power and ethics practiced in everyday conversations, which constitute processes of organizing. Drawing upon narrative frameworks, the analyses of messages posted on an online message board demonstrate people’s imaginative capacity to create relevant stories, in respect of their precise grasp of factual understandings, contextual relevance and evaluative/moral appropriateness, by appropriating others’ words. Based on the empirical analyses, the thesis indicates that studies on power and ethics in organizations can be re-oriented towards appreciating irremediable power imbalances by offering alternative ways of member’s denoting experiences of power.

Molecular tools in the diagnostic and epidemiology of infections caused by members of Mycobacterium avium Complex

Mycobacterium avium Complex (MAC) comprises microorganisms that affect a wide range of animals including humans. The most relevant are Mycobacterium avium subspecies hominissuis (Mah) with a high impact on public health affecting mainly immunocompromised individuals and Mycobacterium avium subspecies paratuberculosis (Map) causing paratuberculosis in animals with a high economic impact worldwide. In this work, we characterized 28 human and 67 porcine Mah isolates and evaluated the relationship among them by Multiple-Locus Variable number tandem repeat Analysis (MLVA). We concluded that Mah population presented a high genetic diversity and no correlations were inferred based on geographical origin, host or biological sample. For the first time in Portugal Map strains, from asymptomatic bovine faecal samples were isolated highlighting the need of more reliable and rapid diagnostic methods for Map direct detection. Therefore, we developed an IS900 nested real time PCR with high sensitivity and specificity associated with optimized DNA extraction methodologies for faecal and milk samples. We detected 83% of 155 faecal samples from goats, cattle and sheep, and 26% of 98 milk samples from cattle, positive for Map IS900 nested real time PCR. A novel SNPs (single nucleotide polymorphisms) assay to Map characterization based on a Whole Genome Sequencing analysis was developed to elucidate the genetic relationship between strains. Based on sequential detection of 14 SNPs and on a decision tree we were able to differentiate 14 phylogenetic groups with a higher discriminatory power compared to other typing methods. A pigmented Map strain was isolated and characterized evidencing for the first time to our knowledge the existence of pigmented Type C strains. With this work, we intended to improve the ante mortem direct molecular detection of Map, to conscientiously aware for the existence of Map animal infections widespread in Portugal and to contribute to the improvement of Map and Mah epidemiological studies.

A+ grandparents at school

Facing an aging society, where there is a large gap between generations and where the elderly are neglected, the Portuguese Red Cross – Delegation of Vila Nova de Gaia – created the project A+: grandparents at school, which encourages intergenerational work. After observing the positive results of the pilot project, the A+ team decided that the project has the potential to be scaled at a national level to enable it to contribute to the integration of the older people in the society, as well as for positive changes of individuals with regard to the elderly. This work project proposes a method to determine whether A+ can be scaled and what is the most efficient way to do it, establishing a process of scale that can be used by every non-profit organization

Implementation of WHO Quality Rights assessment in Kabul Mental Health Hospital

RESUMO: Objetivo Avaliar a qualidade dos serviços de saúde mental e a situação dos direitos humanos no Hospital de Saúde Mental de Kabul (KMHH) e fornecer recomendações para o desenvolvimento de um plano de melhoria, actualização e revisão da Política, Estratégia e Plano Nacionais de Saúde Mental,. Métodos A avaliação foi realizada em Janeiro de 2015 no KMHH e na Burn Ward do Hospital Terciário de Isteqlal por uma equipa multidisciplinar usando Qualidade Direitos Tool Kit da OMS. Antes da avaliação, o protocolo foi aprovado pelo Institutional Review Board e obtido o consentimento informado de cada entrevistado. Realizaram-se entrevistas com 16 utentes do serviço, 17 funcionários do hospital e 7 familiares, além da revisão de documentos e da observação das unidades de internamento do KMHH e das interações interpessoais entre funcionários do hospital e utentes do serviço. A comissão de avaliação reviu também a documentação e observou a Unidade de Queimados do Hospital Terciário de Isteqlal, a fim de avaliar e comparar a paridade entre as duas instalações. Após a avaliação, todos os membros da comissão se reuniram e puseram em conjunto todas as conclusões num relatório final. Resultados Encontrámos algumas lacunas graves no nível de prestação de serviços e no respeito pelos direitos humanos dos utentes dos serviços e dos seus familiares. Uma série de políticas, diretrizes e procedimentos relacionados com os direitos humanos dos pacientes estavam ausentes. O ambiente terapêutico e o padrão de vida eram inadequados, existia má qualidade do atendimento e dos serviços prestados, os utilizadores enfrentavam violações do direito ao exercício da capacidade legal e da liberdade pessoal, eram quimica e fisicamente (uso de correntes) contidos e expostos a abusos verbais, físicos e emocionais, e havia grande ênfase no tratamento institucional. Todos estes aspectos foram considerados como extensa violação dos direitos humanos dos utentes de serviço do KMHH. Conclusão Os serviços disponíveis para utentes dos serviços de saúde mental apresentam alguns problemas devido à desconfiança e falta de consciencialização sobre os direitos das pessoas com doença mental e precisam ser alterados de forma positiva. A Lei de Saúde Mental existente difere muito das recomendações da Convenção sobre os Direitos das Pessoas com Incapacidades (CRPD) e requer revisão e adaptação de acordo com esta Convenção. -------------------------------- ABSTRACT: Objective To assess the quality of mental health services and human rights condition in the Kabul Mental Health Hospital (KMHH) and provide recommendations for development of an improvement plan and to update and revise the National Mental Health Policy, Strategy and Plan. Methods The assessment was conducted in January 2015 in the KMHH and the Burn Ward of Isteqlal Tertiary Hospital by a multidisciplinary team using WHO Quality Rights Tool Kit. Before the assessment, Institutional Review Board approval and informed consent from each interviewee were obtained. Interviews were conducted with 16 service users, 17 hospital staffs and 7 family members in addition to documents review and observation of inpatient units of KMHH plus interpersonal interactions between hospital staff and service users. The assessment committee reviewed the documentation and observed the Burn Ward of Isteqlal Tertiary hospital in order to measure and compare parity between the two facilities. After the assessment, all committee members gathered and synchronized all findings into a final report. Results There were some serious gaps on service provision level and respecting human rights of service users and their family members. A series of policies, guidelines and procedures related to patients’ human rights were absent. Inadequate treatment environment and standard of living, poor quality of care and services, violations of the right to exercise legal capacity and personal liberty, being chemically and physically (e.g. chain) restrained, being exposed to verbal, physical and emotional abuse, and emphasis on institutional treatment were all extensive human rights violation that service users were experiencing in KMHH. Conclusion The available services for mental health service users are questionable due to mistrust and lack of awareness about rights of people with disabilities and need to be positively changed. Existing Mental Health Act has a large number of disparities with the CRPD and requires revision and adaptation in accordance to CRPD.

Hypertension in employees of a University General Hospital

PURPOSE: To find out the prevalence of hypertension in employees of the Hospital and relate it to social demographic variables. METHODS: Blood pressure measurement was performed with a mercury sphygmomanometer, using an appropriate cuff size for arm circumference, weight, and height in a population sample of 864 individuals out of the 9,905 employees of a University General Hospital stratified by gender, age, and job position. RESULTS: Hypertension prevalence was 26% (62% of these reported being aware of their hypertension and 38% were unaware but had systolic/diastolic blood pressures of >140 and/or >90 mm Hg at the moment of the measurement). Of those who were aware of having hypertension, 51% were found to be hypertensive at the moment of the measurement. The prevalence was found to be 17%, 23%, and 29% (P <.05) in physicians, nursing staff, and "others", respectively. The univariate analysis showed a significant odds ratio for the male gender, age >50 years, work unit being the Institute of Radiology and the Administration Building, educational level school, length of work >10 years, and body mass index >30 kg/m². The multivariate logistic regression model revealed a statistically significant association of hypertension with the following variables: gender, age, skin color, family income, and body mass index. CONCLUSIONS: Hypertension prevalence was high, mainly in those who were not physicians or members of the nursing staff. High-risk groups (obese, non-white, men, low family income) should be better advised of prevention and early diagnosis of hypertension by means of special programs.

CEO overconfidence and leverage ratio: Evidence from the founder members of Mila

The study investigates the impact of the managerial overconfidence bias on the capital structure of a sample of 78 firms from Chile, Peru and Colombia, during the years 1996-2014. We infer that there is a positive relation between the leverage ratio and a) the overconfidence; b) the experience and c) the male gender of the executive. Overconfidence is measured according to the status of the CEO (entrepreneur or not-entrepreneur) and the hypotheses are tested through dynamic panel data model. The empirical results show a highly significant positive correlation between overconfidence and leverage ratio and between gender and leverage ratio while, in contrast, the relation between experience and leverage ratio is negative.

Comportamentos das famílias portuguesas em épocas de calor e durante a onda de calor de Agosto de 2003

RESUMO - Este estudo teve como principal objectivo a caracterização das atitudes e da adopção de medidas de protecção em períodos de calor e em particular conhecer aquelas que efectivamente foram adoptadas durante a onda de calor de Agosto de 2003 (29 de Julho a 15 de Agosto). Foi realizado um inquérito por via postal, aplicando um questionário aos indivíduos de 18 e mais anos das unidades de alojamento (UA), que constituem a amostra ECOS (Em Casa Observamos Saúde) do Observatório Nacional de Saúde. Estudaram-se 769 indivíduos, o que correspondeu a 25,6% da totalidade dos indivíduos elegíveis nas UA. Uma vez que a amostra ECOS não é autoponderada, foram ponderados os resultados das unidades de alojamento pela variável do Instituto Nacional de Estatística (INE) «número de famílias clássicas» por região e pela «população residente segundo o nível de instrução» obtidas pelos censos de 2001. Os comportamentos referidos como adoptados em épocas de calor que apresentaram maiores percentagens foram «tomar duches ou banhos» (84,6%), «ingestão de líquidos» (79,6%), «uso de roupa leve, larga e clara» (73,2%) e «tomar refeições leves» (53,7%). Durante a onda de calor de 2003, a maior parte da população (92,5%) leu, ouviu ou viu informação sobre os cuidados a ter durante a onda de calor, tendo sido a televisão (95,2%), a rádio (56,3%) e os jornais (49,3%) os meios de comunicação social mais referidos. Cerca de metade da população (51,4%) informou alguém, fundamentalmente a família, sobre os cuidados a ter. Com efeito, durante esta onda de calor verificou-se um maior cuidado em relação a comportamentos mais prejudiciais em épocas de maior calor. Por um lado, a população portuguesa andou menos ao sol (49,4%), fez menos viagens de carro/transportes à hora do calor (39,8%), realizou menos actividades que exigiriam esforço físico (32,5%) e também houve alguma preocupação em beber menos bebidas alcoólicas (26,5%). Por outro lado, aumentaram os comportamentos que já são mais habituais durante o período de Verão, tais como abrir as janelas durante a noite (40,8%), tomar refeições leves (46,7%), tomar mais duches ou banhos (58,5%), o uso de roupas leves largas e claras (42,5%) e o uso de ventoinhas (37,8%). A alteração do comportamento andar ou estar ao sol sem restrições aumenta com o número de meios de comunicação onde se obteve informação. Abrir as janelas de casa durante a noite e tomar duches ou banhos apresentou uma associação com o número de meios de comunicação onde se obteve informação e com o número de pessoas que prestaram informação. Ingerir líquidos e usar roupa leve, larga e clara mostrou também uma dependência do número de meios de comunicação onde se obteve informação.

On-board electric vehicle battery charger with enhanced V2H operation mode

This paper proposes an on-board Electric Vehicle (EV) battery charger with enhanced Vehicle-to-Home (V2H) operation mode. For such purpose was adapted an on-board bidirectional battery charger prototype to allow the Grid-to-Vehicle (G2V), Vehicle-to-Grid (V2G) and V2H operation modes. Along the paper are presented the hardware topology and the control algorithms of this battery charger. The idea underlying to this paper is the operation of the on-board bidirectional battery charger as an energy backup system when occurs a power outages. For detecting the power outage were compared two strategies, one based on the half-cycle rms calculation of the power grid voltage, and another in the determination of the rms value based in a Kalman filter. The experimental results were obtained considering the on-board EV battery charger under the G2V, V2G, and V2H operation modes. The results show that the power outage detection is faster using a Kalman filter, up to 90% than the other strategy. This also enables a faster transition between operation modes when a power outage occurs.
