Diphyllobothrium latum infection in a non-endemic country: case report

Diphyllobothriasis, which is rarely described in Brazil, was reported initially as a travelers’ disease and as an accidental infection in individuals who ate raw freshwater fish. This report aims to present the case of a 20-year-old patient with confirmed Diphyllobothrium latum infection.

Nosocomial infections in a pediatric intensive care unit of a developing country: NHSN surveillance

INTRODUCTION: This study aimed to determine the epidemiology of the three most common nosocomial infections (NI), namely, sepsis, pneumonia, and urinary tract infection (UTI), in a pediatric intensive care unit (PICU) in a developing country and to define the risk factors associated with NI. METHODS: We performed a prospective study on the incidence of NI in a single PICU, between August 2009 and August 2010. Active surveillance by National Healthcare Safety Network (NHSN) was conducted in the unit and children with NI (cases) were compared with a group (matched controls) in a case-control fashion. RESULTS: We analyzed 172 patients; 22.1% had NI, 71.1% of whom acquired it in the unit. The incidence densities of sepsis, pneumonia, and UTI per 1,000 patients/day were 17.9, 11.4, and 4.3, respectively. The most common agents in sepsis were Enterococcus faecalis and Escherichia coli (18% each); Staphylococcus epidermidis was isolated in 13% of cases. In pneumonias Staphylococcus aureus was the most common cause (3.2%), and in UTI the most frequent agents were yeasts (33.3%). The presence of NI was associated with a long period of hospitalization, use of invasive devices (central venous catheter, nasogastric tube), and use of antibiotics. The last two were independent factors for NI. CONCLUSIONS: The incidence of NI acquired in this unit was high and was associated with extrinsic factors.

Ethical leadership and unethical pro-organizational behavior: A moderated mediation model of affective commitment and authenticity at work

Recently, unethical conduct in the workplace has been a focus of literature and media. Unethical pro-organizational behavior (UPB) refers to unethical conduct that employees engage in to benefit the organization. Given the complexity of UPB, there is an increasing need to understand how and under what conditions this attitude originates within organizations. Based on a sample of 167 employees and seven organizations, results support the moderated mediation model. An ethical leader increases employees’ organizational affective commitment which increases the likelihood to engage in UPB. However, the indirect relationship diminishes when employees feel authentic at work.

Acute kidney injury in a tropical country: a cohort study of 253 patients in an infectious diseases intensive care unit

Introduction: Acute kidney injury (AKI) is a frequent and potentially fatal complication in infectious diseases. The aim of this study was to investigate the clinical aspects of AKI associated with infectious diseases and the factors associated with mortality. Methods: This retrospective study was conducted in patients with AKI who were admitted to the intensive care unit (ICU) of a tertiary infectious diseases hospital from January 2003 to January 2012. The major underlying diseases and clinical and laboratory findings were evaluated. Results: A total of 253 cases were included. The mean age was 46±16 years, and 72% of the patients were male. The main diseases were human immunodeficiency virus (HIV) infection, HIV/acquired immunodeficiency syndrome (AIDS) (30%), tuberculosis (12%), leptospirosis (11%) and dengue (4%). Dialysis was performed in 70 cases (27.6%). The patients were classified as risk (4.4%), injury (63.6%) or failure (32%). The time between AKI diagnosis and dialysis was 3.6±4.7 days. Oliguria was observed in 112 cases (45.7%). The Acute Physiology and Chronic Health Evaluation (APACHE) II scores were higher in patients with HIV/AIDS (57±20, p-value=0.01) and dengue (68±11, p-value=0.01). Death occurred in 159 cases (62.8%). Mortality was higher in patients with HIV/AIDS (76.6%, p-value=0.02). A multivariate analysis identified the following independent risk factors for death: oliguria, metabolic acidosis, sepsis, hypovolemia, the need for vasoactive drugs, the need for mechanical ventilation and the APACHE II score. Conclusions: AKI is a common complication in infectious diseases, with high mortality. Mortality was higher in patients with HIV/AIDS, most likely due to the severity of immunosuppression and opportunistic diseases.

The determinants of mutual fund performance: A cross-country study

We use a new data set to study the determinants of the performance of open–end actively managed equity mutual funds in 27 countries. We find that mutual funds underperform the market overall. The results show important differences in the determinants of fund performance in the USA and elsewhere in the world. The US evidence of diminishing returns to scale is not a universal truth as the performance of funds located outside the USA and funds that invest overseas is not negatively affected by scale. Our findings suggest that the adverse scale effects in the USA are related to liquidity constraints faced by funds that, by virtue of their style, have to invest in small and domestic stocks. Country characteristics also explain fund performance. Funds located in countries with liquid stock markets and strong legal institutions display better performance.

‘Fala connosco!’ : o jornalismo infantil e a participação das crianças, em Portugal e no Brasil

Esta tese se concentra na participação das crianças no jornalismo feito para elas. Buckingham (2009) entende que as crianças devem exercer os seus direitos de participação, estabelecidos na Convenção sobre os Direitos da Criança (1989), também na área da produção midiática. Isto significa que as crianças devem dizer, para os produtores e legisladores de mídia, os seus desejos e sugestões, críticas e concordâncias, além de produzir conteúdos próprios. Para o investigador britânico, isso está relacionado ao que ele chama de “direito das crianças à representação”, garantia que não está abarcada pela Convenção. O objetivo desse novo direito seria o de que as crianças não só sejam ouvidas mas também criem e defendam melhores formas de representação das infâncias contemporâneas, através da participação nos canais de mídia. Além disso, as representações das crianças apresentadas no discurso jornalístico são parte do quadro social e cultural que forma o que entendemos por infância contemporânea (e que a distingue do que é “ser adulto”). A imprensa voltada especificamente para as crianças pode entender melhor o cotidiano dos meninos e meninas e, através de representações da(s) infância(s) mais complexas, pode lembrar à sociedade que as crianças também estão envolvidas em questões gerais, como a organização cultural e socioeconômica de suas cidades, de seus países ou do mundo — expandindo o conceito de infância aceito atualmente. Os canais de participação oferecidos pelos meios de comunicação e as novas formas de comunicação que as crianças têm à sua disposição, através da internet, são possíveis formas de assegurar o direito defendido por Buckingham. Mas as crianças têm vindo a utilizar as novas formas digitais de participação para se comunicar com os jornalistas que escrevem para elas? Existe um interesse voluntário das crianças neste tipo de participação? São comentários enviados diretamente por elas ou por seus responsáveis, preocupados com os conteúdos dos veículos que oferecem aos seus filhos, netos e alunos? Para responder a essas questões, analisamos 515 cartas e e-mails enviados para duas revistas feitas para crianças, no Brasil (“Ciência Hoje das Crianças”) e em Portugal (“Visão Júnior”), em 2013-14. Entrevistamos ainda crianças de nove a 16 anos de idade em ambos os países. Analisando a amostra de mensagens, vimos que os leitores (a maioria crianças, e não adultos responsáveis por elas) escrevem intensamente para ambas as revistas e que eles estão usando mais o e-mail para esta atividade — embora no Brasil não tenham abandonado completamente o papel quando a comunicação é gerada na escola. Nesse país, o uso da internet por crianças nas escolas é menor do que em Portugal. Como conclusões, entendemos que a integração digital não tende a aumentar a comunicação on-line com essas revistas de papel, porém ela expande as fontes de informação acessadas pelas crianças — ainda que elas nem sempre consigam diferenciar entretenimento de informação jornalística. Esses meninos e meninas, voluntariamente ou incentivados pelos professores (aparentemente não por pais ou colegas), veem o espaço para publicação de cartas do leitor nas revistas como uma plataforma por meio da qual podem intervir na oferta editorial. Mas isso acontece de forma “reforçadora”, ou seja, pedindo mais do que eles já veem e apreciam. Acreditamos ser necessário investimento em literacia midiária, através da mediação dos pais e da escola, para estimular as crianças a pedirem um jornalismo melhor, de uma forma que elas ainda nem sabem ser possível. //

Challenges and confusion in media regulation: a four-country comparison

[Excerto] ln this chapter we discuss recent developments and challenges in European media and communication policy, focusing on the period following the 2008 global financial crisis. We are especially interested in the implications of the financial crisis and its political repercussions nationally (austerity measures and cuts to public services, growing anti-politics sentiments and widespread dissatisfaction with free-market capitalism and representative democracy) for media and communication policy, understood here in a broad sense, so as to include ali electronic communications, such as the Internet, mobile communications, social media etc. Our overarching concern is with the implications of developments in media and communication policy for the democratic functions of the media in Europe (...).

Educating for sociability and learning for citizenship: developing communicational skills and mediation in educational contexts

This text concerns a program about the Promotion of Social and Communicational Skills and Mediation (PSCSM) developed with children aged between 10 and 13 years in a non-formal educational institution. The program of intervention had, as its purpose, the promotion of social and communicational competencies and mediation, thus enabling the children involved to have a healthy and responsible sociability in the different contexts in which they find themselves: family, school, peer group, amongst others. It was developed over 13 sessions with objectives and activities intentionally planned with the view of promoting competencies of communication, co-operation, responsibility, a critical spirit, solidarity, autonomy, respect, integration, inclusion and the recognition of rights and duties. This work was carried out with an action-research methodology that resorted to various techniques and instruments to gather and record information. The results obtained showed the impact and benefits of the program and they also revealed the necessity of educational institutions investing in the promotion of an ethical literacy and the empowerment of the children and young people for healthy sociability and active citizenship.
