relatório de estágio desenvolvido com vista à obtenção de grau de Mestre em Geografia Física e Ordenamento do Território, visa demonstrar que a cidade de Lisboa tem aptidão potencial para a construção de “telhados verdes”, os quais podem melhorar o ambiente citadino através de benefícios energéticos, ambientais e económicos, e o possível crescimento de áreas verdes nesta cidade. Para alcançar aquele objectivo geral, identificaram-se os edifícios que reuniam as condições ideais para a implementação de telhados verdes ou “green roofs” na cidade de Lisboa e consequentemente, o aumento dos seus espaços verdes. São, por isso, objectivos específicos: (i) Identificar os edifícios com coberturas que não sejam de alvenaria; (ii) Identificar as áreas da cidade onde é possível a construção dos telhados verdes; (iii) Correlacionar as áreas com espaços verdes na cidade de Lisboa com a potencial área de construção dos telhados verdes. Para atingir os objectivos específicos mencionados foi utilizada uma imagem QuicKbird-2 de uma área da cidade de Lisboa, o que permitiu, com recurso a ferramentas de detecção remota e Sistemas de Informação Geográfica, identificar os diferentes tipos de cobertura dos edifícios urbanos, podendo estes serem potenciais candidatos à construção de “green roofs” em Lisboa.

A praia do Guincho é mundialmente reconhecida no âmbito dos desportos náuticos, especificamente no Windsurf e no Kitesurf, devido aos ventos violentos e à forte agitação marítima. Estes desportos náuticos requerem condições meteorológicas particulares e os praticantes baseiam-se nos modelos de previsão disponíveis em livre acesso para obter as informações necessárias relativas ao comportamento do vento na praia. Estes modelos de previsão raramente correspondem ao vento observado em tempo real. Assim, este estudo tem como objectivo realizar uma comparação entre os fenómenos de vento previstos e observações dos fenómenos que realmente acontecem na praia. Desta forma, é apresentada uma classificação de dias com vento no Guincho a fim de se compararem as previsões com o que ocorre na realidade.

The literature has shown a significant decrease in failure rates when the anterior cruciate ligament (ACL) reconstruction was associated with an extra-articular reinforcement technique such as the anterolateral ligament (ALL) or the iliotibial band tenodesis (ITBT) using the modified Lemaire technique. As much as there is a progressive decrease in the failure rates of ACL reconstructions when the ALL reconstruction technique is associated, there are still and will be cases that will result in graft rupture. These cases will require more alternatives for revision, which are always challenging for the surgeon, where the lateral approaches represent complicating factors, especially because of the distortion of the lateral anatomy (by the previous approach for ALL reconstruction), previous reconstruction tunnels, and the presence of fixation materials. We present here a safe technique that offers great stability to the fixation of the graft and is easy to perform, using a single tunnel for the passage of the ACL and ITBT grafts, allowing a single fixation for both. In this way, we performed a lower-cost surgery, with a lower risk of lateral condyle fracture and tunnel confluence. This technique is indicated to be used in cases of revision after failure of combined ACL reconstruction with ALL.

Background: The COVID-19 pandemic has devastatingly affected Long-Term Care Facilities (LTCF), exposing aging people, staff members, and visitors. The world has learned through the pandemic and lessons can be taken to adopt effective measures to deal with COVID-19 outbreaks in LTCF. We aimed to systematically review the available evidence on the effect of measures to minimize the risk of transmission of COVID-19 in LTCs during outbreaks since 2021. Methods: The search method was guided by the preferred reporting items for systematic reviews (PRISMA) and the reporting guideline synthesis without meta-analysis (SWiM) in systematic reviews. The search was performed in April 2023. Observational and interventional studies from the databases of PubMed, Web of Science, Scopus, Cochrane Systematic Reviews, CINAHL, and Academic Search were systematically reviewed. We included studies conducted in the LTCF with outbreaks that quantitatively assess the effect of non-pharmacological measures on cases of COVID-19. Two review authors independently reviewed titles for inclusion, extracted data, and undertook the risk of bias according to pre-specified criteria. The quality of studies was analyzed using the Joanna Briggs Institute Critical Appraisal. Results: Thirteen studies were included, with 8442 LTCF experiencing COVID-19 outbreaks and 598 thousand participants (residents and staff members). Prevention and control of COVID-19 infection interventions were grouped into three themes: strategic, tactical, and operational measures. The strategic measures reveal the importance of COVID-19 prevention and control as LTCF structural characteristics, namely the LTCF size, new admissions, infection control surveillance, and architectural structure. At the tactical level, the lack of personal and long staff shifts is related to COVID-19's spread. Operational measures with a favorable effect on preventing COVID-19 transmission are sufficient. Personal protective equipment stock, correct mask use, signaling, social distancing, and resident cohorting. Conclusions: Operational, tactical, and strategic approaches may have a favorable effect on preventing the spread of COVID-19 in LTCFs experiencing outbreaks. Given the heterogeneous nature of the measures, performing a meta-analysis was not possible. Future research should use more robust study designs to explore similar infection control measures in LTCFs during endemic situations with comparable outbreaks. Trial registration: The protocol of this systematic review was registered in PROSPERO (CRD42020214566).

Background: The first medical oncology appointment serves as a platform for patients to comprehend their diagnosis and prognostic implications of cancer. This study aimed to determine patients' communication preferences during their first medical oncology appointment and to assess the disparities between patients' preferences and perceptions. Methods: A total of 169 cancer patients participated by completing the Communication in First Medical Oncology Appointment Questionnaire (C-FAQ), a two-section questionnaire designed to assess patients' preferences and perceptions regarding Content (information provided and its extent), Facilitation (timing and location of information delivery), and Support (emotional support) during their first medical oncology appointment. A comparative analysis was conducted to assess the variations between preferences and perceptions. Results: Content emerged as the most significant dimension compared to Facilitation and Support. The physician's knowledge, honesty, and ability to provide clear information were considered the most important attributes. Patients evaluated most of their preferences as "very important". Patients' perception of the communication dimensions present during their appointment was below preferences for 11 items, indicating significant discrepancies in clinical practice. Conclusions: Patients highly valued their preferences concerning Content, Facilitation, and Support dimensions of communication. However, patient preferences were more prominently oriented towards the Content dimension. The discrepancies between preferences and perceptions should be viewed as an opportunity for enhancing communication skills through training.
