Etiologia das infeções respiratórias virais em criançass em idade pré-escolar

RESUMO: Os vírus respiratórios continuam a ocupar um papel relevante na morbilidade e mortalidade infantil, tendo na última década sido alargado o espectro de vírus potencialmente causadores das infeções respiratórias. O diagnóstico destas infeções pode ser efetuado por várias metodologias, sendo as técnicas de biologia molecular consideradas as mais sensíveis para este fim. No âmbito do Projeto Ambiente e Saúde em Creches e Infantários (ENVIRH) foi efetuada uma comparação da prevalência dos principais vírus respiratórios em crianças em idade pré-escolar, com critérios de infeção respiratória, recorrendo a técnicas de biologia molecular, em duas populações: crianças que se encontravam na escola/domicilio e crianças que recorreram a uma urgência hospitalar. O estudo decorreu em dois períodos, de Fevereiro a Maio de 2011 e de Outubro de 2011 a Abril de 2012. Foram efetuadas duas colheitas de zaragatoas, uma nasal e outra orofaríngea. A metodologia utilizada para a identificação viral nas amostras foi a PCR e RT-PCR multiplex em tempo real. Os vírus pesquisados foram: Influenza A e B, Parainfluenza 1-4, Metapneumovirus humano, Vírus Sincicial respiratório (VSR), Rinovírus, Enterovírus, Coronavírus e Bocavirus. Foram realizadas 100 colheitas em crianças com idades compreendidas entre os 5 meses e os 5 anos. Foram obtidas 64 amostras dos infantários/domicílios, das quais 47 foram positivas. Da urgência Hospitalar obtiveram-se 36 amostras, em que 32 foram positivas. O vírus da gripe A (H3) foi o mais frequentemente detetado nas duas populações, mas apenas durante o surto de 2012. O VSR e os adenovírus foram mais frequentes nas crianças que recorreram ao hospital, ao contrário dos enterovirus e dos coronavírus, que não foram detetados nesta população. Os bocavirus nunca foram detetados isoladamente. Este estudo reforça a importância de se utilizarem técnicas de biologia molecular para o diagnóstico etiológico das infeções respiratórias, devido à elevada sensibilidade das mesmas, o que se reflete na elevada percentagem de amostras positivas. O facto de se utilizarem técnicas “multiplex”, que permitem a pesquisa simultânea de vários vírus, facilita a deteção de um maior espectro destes agentes. A elevada prevalência de Influenza A H3N2 deveu-se ao facto de grande parte do estudo ter coincidido com um período de surto por este vírus. O sistema de alerta montado durante o projeto ENVIRH pareceu promissor para uma eventual utilização futura em períodos de atividade gripal.--------------ABSTRACT: In the last decade, as respiratory viruses keep representing a relevant factor in child morbidity and mortality, the spectrum of viruses that may potentially cause respiratory infections has been widened. Within the several methodologies that may be applied in the diagnosis of these types of infections, the ones that use molecular biology are considered to be the most sensitive. The Environment and Health in Daycares and Nurseries Project (ENVIRH) arranged for a study, by means of molecular biology techniques, on the main respiratory viruses' influence in pre-school aged children with respiratory infection symptoms. This study compared children in two different populations: children at school or at home and children that were taken to a hospital emergency service. The study was conducted in two different time periods, one from February to May 2011 and the other from October 2011 to April 2012. During this time, two swab collections were held, one nasal and one oropharyngeal. PCR and RT-PCR multiplex in real time techniques were used for viral identification of the samples, searching for the viruses Influenza A and B, Parainfluenza 1-4, human Metapneumovirus, Respiratory Sincytial Virus (RSV), Rhinovirus, Enterovirus, Coronavirus and Bocavirus. One hundred (100) collections were held in children between the ages of 5 months and 5 years, sixty-four (64) at home/school and thirty-six (36) at the hospital's emergency service. From a total of seventy-nine (79) positive samples, forty-seven (47) were obtained at home/school and thirty-two (32) at the hospital. The virus detected the most in both populations was the Influenza A (H3), but only during the outbreak of 2012. Unlike the enteroviruses and coronaviruses, that were not detected within this population, the RSV and the adenoviruses were most common within the children at the hospital. Bocaviruses were never detected isolated from other viruses. The high percentage of positive samples reinforces the significance of using molecular biology techniques for the etiological diagnosis of respiratory infections. The use of multiplex techniques, that make the simultaneous search for multiple viruses possible, enhances the detection of a larger spectrum of such agents. Most of the study coincided with an outbreak of the Influenza A H3N2 virus, thus explaining the high number of its cases identified. The alert system set up during the ENVIRH project looked promising enough for eventual periods of flu activity in the future.

O abuso de informação privilegiada (insider trading)

In the stock market, information takes on special relevance, due to the market’s permanent updating and the great fluidity of information existent therein. Just as in any other negotiations, the party with the better information has a bargaining advantage, as it is able to make more advantageous business decisions. However, unlike most other markets, the proper functioning of the stock market is greatly dependent on investors’ trust in the market itself. As such, if there are investors who, due to any condition they possess or office they hold, have access to relevant information which is not accessible to the general public, distrust is bred within the market and, consequently, investment is lessened. Thus, there is a need to prevent those who hold privileged information from using it in abusive ways. In Portugal, abuse of privileged information is set out and punished criminally in Article 378. of the Portuguese Securities Code (‘Código dos Valores Mobiliários’). In this dissertation, I have set out, firstly, to analyze the inherent conditions for there to be a crime of abuse of privileged information; secondly, to analyze two well-known cases, which took place and were decided in other jurisdictions, and attempt to understand how these cases would fall under Article 378. of the Portuguese Securities Code. Whereas the first case, Chiarella v. United States, was scrutinize under Article 378 of the Portuguese Securities Code, in the second, Lafonta v. AMF, the conclusion arrived at was that the crime taken place was different. This analysis allowed, on one hand, the application to a particular case of prerequisites and concepts which were explained, at a first approach, from a more theoretical perspective; on the other hand, it also allowed the further development of specific aspects of the regime, namely the difference between an insider and a tipee, as well as to more clearly set out the limits to the precise character of the information at hand.

Implementation of a pilot project for the treatment and prevention of substance abuse in children and adolescents : strengthening families for parents and youths 12-16

RESUMO: Antecendentes: Uma avaliação dos serviços de abuso de substâncias em Barbados identificou a necessidade de programas e serviços que são projetados especificamente para crianças e adolescentes. Objetivo: Realizar programa com base em evidências para reduzir a incidência de abuso de drogas entre crianças e adolescentes por meio do fortalecimento da unidade familiar através de parentalidade positiva, de maior funcionamento familiar e de resistência dos jovens. Método: Dois projetos-piloto foram realizadas com base no programa "Fortalecer as Famílias para Pais e Jovens de 12 a 16 anos (SFPY). O programa de nove semanas foi empregado como uma intervenção para criar laços familiares mais fortes, aumentar a resistência dos jovens e reduzir o abuso de drogas entre crianças e adolescentes de idades de 11 a 16 anos. A decisão foi tomada para incluir participantes de 11 anos desde que as crianças possam estar no primeiro ano da escola secundária nessa idade. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 5 Resultados: Quinze famílias participaram em dois projetos-piloto e a avaliação final mostrou que os jovens após o programa, geralmente tornaram-se mais positivos sobre o seu lugar na unidade familiar e sentiram que sua participação no programa foi benéfica. Os pais, da mesma forma, relataram que eles conquistaram, com o programa uma relação mais positiva, uma melhor compreensão das necessidades, e consciência das mudanças de desenvolvimento de seus jovens. Desta forma, considera-se que o programa atingiu o resultado desejado de criar unidades familiares mais fortes. Conclusão: O Projeto Piloto “SFPY” foi bem sucedido em fazer pais e jovens mais conscientes de suas necessidades individuais e de responsabilidades dentro da unidade familiar. Como resultado, o relacionamentos das respectivas famílias melhorou. Estudos baseados em evidências têm demonstrado que um relação familiar mais forte diminui a incidência de uso e abuso de drogas na população adolescente, aumentando os fatores de proteção e diminuindo os fatores de risco. A implementação do programa, que foi desenvolvido e testado no ambiente norte-americano, demonstrou que era transferível para a sociedade de Barbados. No entanto, seu impacto total só pode ser determinado através de um estudo comparativo envolvendo um grupo de controle e / ou uma intervenção alternativa ao abuso de substâncias. Portanto, é recomendável que um estudo comparativo da intervenção SFPY deve envolver uma amostra representativa de adolescentes que estão em estágio de desenvolvimento anterior mais cedo. Evidências já demonstram que o programa é mais eficaz, com impacto mais longo sobre os jovens que participam em uma idade maisABSTRACT:Background: An evaluation of substance abuse services in Barbados has identified the need for programmes and services that are specifically designed for children and adolescents. Aim: To conduct an evidence-based programme to reduce the incidence of substance abuse among children and adolescents by strengthening the family unit through positive parenting, enhanced family functioning and youth resilience. Method: Two pilot projects were conducted based on the ‘Strengthening Families for Parents and Youths 12– 16’ (SFPY) programme. The nine-week programme was employed as an intervention to create stronger family connections, increase youth resiliency and reduce drug abuse among children and adolescents between the ages of 11 to 16. The decision was made to include participants from age 11 since children may be in the first year of secondary school at this age. IMPLEMENTATION OF SUBSTANCE ABUSE PILOT PROJECT FOR CHILDREN AND ADOLESCENTS 3 Results: Fifteen families participated in two pilot projects and an evaluation conducted at the conclusion showed that the youth were generally more positive about their perceived place in the family unit and felt that the being in the programme was generally beneficial. The parents similarly reported they had a more positive relationship with their youths and also had a better understanding of their needs, and an awareness of their developmental changes. This affirmed that the programme had achieved its desired outcome to create stronger family units. Conclusion: The SFPY Pilot Project was successful in making parents and youths more aware of their individual needs and responsibilities within the family unit. As a result relationships within their respective families were strengthened. Evidence-based studies have shown that enhanced family functioning decreases the incidence of substance use and abuse in the adolescent population by increasing protective factors and decreasing risk factors. The implementation of the programme, which was developed and tested in the North American environment, demonstrated that it was transferable to the Barbadian society. However, its full impact can only be determined through a comparative study involving a control group and/or an alternative substance abuse intervention. It is therefore recommended that a comparative study of the SFPY intervention should be delivered to a representative sample of adolescents who are at an earlier developmental stage. Evidence has shown that the programme is more effective, with longer impact on youths who participate at a younger age.

Evaluation of outpatient child-adolescent mental health services (CAMHS) in Attica-Greece

ABSTRACT: Background: Childhood is a critical time for social and emotional development, educational progress and mental health prevention. Mental health for children and adolescents is defined by the achievement of expected developmental, cognitive, social and emotional skills. The development of child-adolescent mental health services (CAMHS) is a necessity for each country, not only as a prevention measure for the wellbeing of people, but also as an investment to the future of countries. Qualitative evaluation of services is the only way to ensure whether services function under quality standards and increase the possibility of better outcomes for their patients. This study examines the greek outpatient CAMHS against the British Standards of National Institute of Excellence for community CAMHS. The Standards assessed refer to the areas of Assessment, Care and Intervention. Objectives: The main objectives of the study are 1) to evaluate Greek outpatient CAMHS in the Attica region 2) to promote the evaluation process for mental health services in Greece. Methods: Due to the fact that Greek services are based on the British model, the tool used was the British self-review questionnaire of Quality Network for Community CAMHS(QNCC).The tool was translated, adapted and posted to services. Twelve out of twenty outpatient CAMHS of Attica (including Athens) responded. Data was collected and performed by the Statistical Package for Social Sciences SPSS. Results: The study resulted that the CAMHS examined, meet moderately the British Standards of 1) Referral and Access, 2) Assessment & Care planning, 3) Care & Intervention. Two out of twelve services examined, meet the standards of "Assessment and Care" in a higher percentage between 75% and 100%. Conclusions: The paper describes a satisfactory function of CAMHS in Attica prefecture taking into consideration the extremely difficult political situation of Greece at the time of the research. Strong and weak domains are identified. Also the translation and adaptation of British tools promote the evaluation process and quality assurance of Greek CAMHS.
