Estudo de validação da escala LIPT-60 para professores portugueses.

Os estudos sobre o mal-estar na profissão docente surgiram com algum destaque apenas a partir dos anos 80, sendo que até então os estudos sobre saúde ocupacional e stress diziam respeito a profissões de risco como controladores de tráfego aéreo, polícias, executivos ou enfermeiras que trabalhavam com casos críticos de doença e morte (Cooper & Kelly, 1993). Tal destaque deveu-se por um lado ao movimento de globalização e necessidade de reformas educativas (Lima & Lima-Filho, 2009) e por outro, à visibilidade desta problemática ao nível social, despoletando o interesse da investigação em compreender os seus contornos.Este estudo tem como finalidade a validação portuguesa da escala LIPT-60 para professores portugueses.FCT e três projetos ENABLIN+ (Leonardo Da Vinci), Cognition & Inclusion (ERASMUS+) e LLL-HUB (Lifelong Learning Programm) e da I Conferência Europeia em Life Long Learning (realizada na Universidade de Évora com os apoios do Departamento de Psicologia e da Escola de Ciências Sociais), e da Associação Portuguesa de Gestão de Pessoas (APG) e a Associação Nacional para a Qualificação e Ensino Profissiona

Prevalência de doença cardiovascular numa população de doentes com síndrome de apneia obstrutiva do sono

Introdução: A Síndrome de Apneia Obstrutiva do Sono (SAOS) induz uma série de alterações fisiopatológicas que aumentam o risco de desenvolvimento de doenças cardiovasculares. Entre estas, a hipertensão arterial (HTA) tem sido a mais estudada e cuja associação causal está mais bem estabelecida. Existem poucos dados sobre a prevalência destas patologias nos doentes com SAOS em Portugal. Tipo de estudo: Análise retrospectiva. Métodos: Determinação da prevalência de patologias cardiovasculares e sua relação com os vários graus de gravidade da SAOS, mediante a análise dos processos de 305 doentes com diagnóstico de SAOS seguidos na Consulta de Patologia do Sono do nosso Hospital. Resultados: Verificou-se uma prevalência de doenças cardiovasculares de 76,7%, sendo a HTA a mais frequente (60%), seguida da cardiopatia isquémica (11,8%) e das disritmias (10,8%). Outros factores de risco cardiovasculares como a obesidade (61,3%), diabetes (20,3%), dislipidemia (43,3%) e tabagismo (49,8%) foram também encontrados num elevado número de doentes. Conclusão: Detectou-se uma elevada prevalência de HTA, pelo que num doente com o diagnóstico de HTA deve ser sempre avaliada a possibilidade de existência de SAOS. Por outro lado, a constatação de uma prevalência elevada de outros factores de risco cardiovascular potencia uma maior morbilidade e mortalidade nos doentes com SAOS

Livro Verde dos Montados

O Livro Verde dos Montados apresenta diversos objectivos que se interligam: Em primeiro lugar, o Livro Verde pretende reunir e sistematizar, de uma forma simples e acessível ao público, o conhecimento produzido em Portugal pelos investigadores e técnicos de várias instituições de investigação ou de gestão que estudam o Montado. Assume-se como uma oportunidade de caracterizar o sistema tendo em conta as suas várias dimensões, identificando as principais ameaças à sua preservação assim como os caminhos que podem ajudar à sua sustentabilidade. Não sendo um documento científico, baseia-se no conhecimento científico e pretende constituir a base para uma plataforma de organização, tanto dos investigadores como do conhecimento científico actualmente produzido em Portugal sobre o Montado.Em segundo lugar, o Livro Verde deverá contribuir para um entendimento partilhado do que é o Montado, por parte do público, de técnicos e de especialistas, conduzindo a uma classificação mais clara do que pode ser considerado Montado e de quais os tipos distintos de Montados que podem ser identificados. Em terceiro lugar, o Livro Verde estabelece as bases para uma estratégia coordenada de disponibilização de informação sobre o sistema Montado, visando o seu conhecimento, apreciação e valorização pela sociedade portuguesa no seu conjunto. Deste modo, o Livro Verde poderá constituir um instrumento congregador e inspirador para a realização de acções de sensibilização e informação sobre o Montado. Em quarto lugar, pretende-se que o Livro Verde contribua para um maior reconhecimento e valorização do Montado como sistema, a nível do desenho das políticas nacionais por parte dos vários sectores envolvidos.Finalmente, o Livro Verde constituirá um documento parceiro do Livro Verde das Dehesas, produzido em Espanha em 2010, de forma a reforçar o reconhecimento e a devida valorização destes sistemas silvo-pastoris no desenho das estratégias e políticas relevantes pelas instituições europeias. Em suma, os autores pretendem que o Livro Verde dos Montados se afirme como o primeiro passo para uma efectiva definição e implementação de uma estratégia nacional para os Montados

Clinical outcomes of a cohort of patients with central nervous system metastases from thyroid cancer

Introduction: Metastases to central nervous system (M1-CNS) are rarely reported in thyroid cancer (TC) patients. We aimed to characterize patients with M1-CNS from TC followed in our department. Methods: Review of the medical records of 27 patients with TC-related M1-CNS. Results: Mean age at TC diagnosis was 56.9 ± 19.1 years. Papillary TC (55.6%) was the commonest histological type, followed by poorly differentiated (18.5%), medullary (11.1%), follicular (7.4%) and Hürthle cell (7.4%) carcinomas. Angioinvasion and extrathyroidal extension were observed in a high number of patients. At M1-CNS diagnosis, other distant metastases were already present in 77.8% of the patients. Treatment directed to M1-CNS was offered to 20 (74%) patients: 1 was submitted to surgery, 18 to radiotherapy (either whole-brain radiotherapy or stereotaxic radiosurgery or both) and 4 to surgery and radiotherapy. Four patients received cytotoxic chemotherapy and one was submitted to 131I. Median survival since M1-CNS detection was 5.0 months. The only factor associated with better survival was surgery to brain metastases (P = 0.012). Conclusions: The management of these patients is very challenging given the inexistence of effective treatments, except for brain surgery in selected cases

Extending the Impact of RAC1b Overexpression to Follicular Thyroid Carcinomas

RAC1b is a hyperactive variant of the small GTPase RAC1 known to be a relevant molecular player in different cancers. Previous studies from our group lead to the evidence that its overexpression in papillary thyroid carcinoma (PTC) is associated with an unfavorable prognosis. In the present study, we intended to extend the analysis of RAC1b expression to thyroid follicular neoplasms and to seek for clinical correlations. RAC1b expression levels were determined by RT-qPCR in thyroid follicular tumor samples comprising 23 follicular thyroid carcinomas (FTCs) and 33 follicular thyroid adenomas (FTAs). RAC1b was found to be overexpressed in 33% of carcinomas while no RAC1b overexpression was documented among follicular adenomas. Patients with a diagnosis of FTC were divided into two groups based on longitudinal evolution and final outcome. RAC1b overexpression was significantly associated with both the presence of distant metastases (P = 0.01) and poorer clinical outcome (P = 0.01) suggesting that, similarly to that previously found in PTCs, RAC1b overexpression in FTCs is also associated with worse outcomes. Furthermore, the absence of RAC1b overexpression in follicular adenomas hints its potential as a molecular marker likely to contribute, in conjunction with other putative markers, to the preoperative differential diagnosis of thyroid follicular lesions

Cervical Lymph Node Schwannoma—An Unexpected Diagnosis

Introduction: Schwannomas—Schwann cells–originating tumors—may develop in many locations. However, primary schwannomas arising within lymph nodes are extremely rare, with only a few cases described to this date in the English literature. For the intranodal location, most of the cases are described in the abdominal cavity. In these cases, clinicians may consider and check for familial disorders, such as neurofibromatosis type 2 (NF2) and schwannomatosis also called neurofibromatosis type 3. Schwannomas are benign neoplasms. Histologically, differential diagnosis for spindle-cell lesions in lymph nodes is important and must be done carefully, mainly because they may be attributable to metastatic disease. We report a case of a primary schwannoma arising in a cervical lymph node. Background: Primary schwannomas arising within lymph nodes are extremely rare, with only a few cases reported. Since they are benign neoplasms, the differential diagnosis with other intranodal spindle cell lesions, mostly malignant, is important. Methods: An asymptomatic 69-year-old woman, previously submitted to left hemithyroidectomy for a benign folicular nodule, underwent thyroidectomy totalization following the identification of a large thyroid nodule in routine evaluation. Results: Gross and microscopic examination and ancillary studies were consistent with the diagnosis of intranodal schwannoma. The patient had acquired bilateral hypoacusia. Therefore, type 2 neurofibromatosis was considered and vestibular schwannomas ruled out. Conclusion: Herein, we present the second case of a primary schwannoma in a cervical lymph node reported so far. The relevance of the differential diagnosis is highlighted

Conservation zones promote oak regeneration and shrub diversity in certified Mediterranean oak woodlands

Mediterranean oak woodlands are ecosystems of high conservation and socio-economic value that occur in Southwestern Europe, North Africa and California. Oak regeneration failure is occurring in these ecosystems and may be endangering their long-term conservation. Most studies suggest that inadequate management practices may be contributing to oak regeneration failure. Forest certification is a voluntary type of certification, based on third-party auditing of compliance with performance-based sustainable management standards that has been expanding in forest ecosystems worldwide, including in Mediterranean oak woodlands. The Forest Stewardship Council (FSC) certification is the dominant certification scheme in Mediterranean oak woodlands and requires landowners to establish conservation zones in their estates. Conservation zones usually correspond to a tenth of the estate and are primarily managed for biodiversity conservation. In spite of recent studies reporting positive effects of FSC certification and conservation zones on biodiversity and forest structure in tropical regions, its effects on tree regeneration in Mediterranean oak woodlands are unknown. In this study, conducted in Southwestern Europe, we compared the abundance of cork oak (Quercus suber) regeneration and the cover, richness and diversity of Mediterranean shrublands between conservation and non-conservation zones in FSC certified cork oak woodlands. We found that in conservation zones oak regeneration was more abundant and that species richness and diversity of shrubs were significantly higher. Our results suggest that the creation of set-aside areas in cork oak woodlands, such as conservation zones, may help avert the tree regeneration crisis this ecosystem is facing.</p
