Eventos de turismo desportivo e desenvolvimento local sustentável: avaliação dos impactos da EDP Meia Maratona de Coimbra

Num contexto em que começam a ser reconhecidas as potencialidades dos eventos de turismo desportivo de pequena escala no desenvolvimento local sustentável, e existindo em Portugal poucos estudos que analisem os impactos destes eventos, centrando-se a maior parte deles na análise dos grandes eventos, interessa analisar os small-scale events. Em concreto, se estes permitem compatibilizar a atividade turística com a salvaguarda dos recursos naturais, a preservação do ambiente, o desenvolvimento económico e a qualidade de vida da população local, garantindo, assim, a sustentabilidade em todas as suas dimensões. É neste contexto que surge o presente estudo, com o objetivo de identificar os impactos económicos, sociais e ambientais da EDP Meia Maratona de Coimbra em termos de desenvolvimento local sustentável. O modelo metodológico seguido incluiu um inquérito por questionário, aplicado a todos os participantes e uma entrevista à entidade organizadora do evento. Os resultados sugerem que face à satisfação geral com a organização do evento, ao impacto económico positivo, às sinergias conseguidas com entidades e população local, à implementação de medidas de preservação ambiental e utilização de recursos existentes, o evento pode revelar-se uma forma viável de turismo sustentável. Assim, a continuidade do evento estudado constitui uma boa aposta como estratégia de promoção turística da cidade

Transesophageal pulmonary lobectomy with single transthoracic port assistance: study with survival assessment in a porcine model

BACKGROUND AND STUDY AIMS: Thoracoscopic pulmonary lobectomy is being performed in an increasing number of patients. The aims of the current study were to assess natural orifice transluminal endoscopic surgery (NOTES) as an alternative to transthoracic endoscopic surgery, and to test the feasibility of peroral transesophageal right upper pulmonary lobectomy with the assistance of a single transthoracic trocar. METHODS: In 10 acute and 4 survival pigs, right upper pulmonary lobectomy was performed using a forward-viewing double-channel gastroscope and an operative thoracoscope with a 5-mm working channel inserted through a single transthoracic 12-mm) port. Time, safety, and feasibility of the following steps were recorded in all animals: esophagotomy, hilar dissection, individual ligation of the hilum elements, pulmonary lobectomy, and specimen retrieval. In the survival experiments, esophagotomy was closed using a reticulated laparoscopy suture device and an esophageal stent was placed. These animals were kept alive and monitored for 2 weeks. RESULTS: Esophagotomy was performed safely in all animals (mean procedure duration 5.4 ± 1.7 minutes). Dissection of the right upper lobe hilum elements (bronchus, arteries, and veins) was carried out without adverse events. Individual ligation of the hilum elements was performed in all but two cases (time for dissection and ligation 44.2 ± 14.8 minutes). Lobectomy and specimen retrieval were completed in all animals (9.5 ± 3.1 minutes). Esophagotomy closure and stent placement were carried out in 20.0 ± 2.8 minutes in the survival animals. These animals fed normally and gained weight postoperatively without signs of disease. Endoscopic examination before necropsy revealed a pseudo-diverticulum in one animal, and wound dehiscence with confined collection/recess in the remaining animals. CONCLUSIONS: Transesophageal right upper pulmonary lobectomy using single transthoracic trocar assistance is feasible and may represent a step towards scar-free pulmonary lobectomy.This project was funded by the FCT Grants project PTDC/SAUOSM/105578/2008

Left atrial appendage ligation with single transthoracic port assistance : a study of survival assessment in a porcine model (with videos)

Background: Left atrial appendage (LAA) exclusion is a well-known procedure for the prevention of stroke in high-risk patients with atrial fibrillation and contraindication to long-term oral anticoagulant therapy. Objective: To evaluate a natural orifice transluminal endoscopic surgery (NOTES) approach for LAA ligation. Design: In 4 acute and 6 survival pigs, we performed LAA by using a forward-viewing, single-channelgastroscope and an operative thoracoscope with a 3-mm working channel (introduced through an 8-mm single transthoracic port). Setting: Animal laboratory. Interventions: The gastroscope was introduced in the thoracic cavity through an esophageal submucosal tunnel. An end loop introduced through the gastroscope was used to legate the LAA. In the survival experiments, the esophageal mucosa was closed using hemoclips. Main Outcome Measurements: The time, safety, and feasibility of the procedure were recorded. In the survival experiments, endoscopy and postmortem examination were performed on postoperative day 14. Results: Creation of a submucosal tunnel and esophagotomy were safely performed in all animals without incidents. The mean time for esophagotomy was 17.0 6.3 minutes. Pericardial dissection and LAA ligation were performed in all animals but 1. The mean time for LAA ligation was 34.4 19.1 minutes. No adverse events occurred during the survival period. Endoscopy showed complete esophageal closure. Postmortem examination revealed pleural adhesions on the site of pericardial dissection, and the LAA was fibrotic with the endoloop in place. Limitations: Animal study. Conclusions: LAA ligation with single transthoracic trocar assistance is feasible and may be an alternative to anticoagulant therapy or to permanent intracardiac implants in patients with atrial fibrillation.This project was funded by the Grants FCT project PTDC/SAU-OSM/105578/2008

Synthetic cannabinoids (SCs) are synthetic analogs of Δ9-tetrahydrocannabinol (Δ9-THC), the psychotropic compound of cannabis, acting as agonists of eCB receptor CB1. SC is an easily available and popular alternative to cannabis, and their molecular structure is always changing, increasing the hazard for the general population. The popularity of cannabis and its derivatives may lead, and often does, to a child's exposure to cannabis both in utero and through breastfeeding by a drug-consuming mother. Prenatal exposure to cannabis has been associated with an altered rate of mental development and significant changes in nervous system functioning. However, the understanding of mechanisms of its action on developing the human CNS is still lacking. We investigated the effect of continuous exposure to cannabinoids on developing human neurons, mimicking the prenatal exposure by drug-consuming mother. Two human induced pluripotent stem cells (hiPSC) lines were induced to differentiate into neuronal cells and exposed for 37 days to cannabidiol (CBD), Δ9-THC, and two SCs, THJ-018 and EG-018. Both Δ9-THC and SC, at 10 μM, promote precocious neuronal and glial differentiation, while CBD at the same concentration is neurotoxic. Neurons exposed to Δ9-THC and SC show abnormal functioning of voltage-gated calcium channels when stimulated by extracellular potassium. In sum, all studied substances have a profound impact on the developing neurons, highlighting the importance of thorough research on the impact of prenatal exposure to natural and SC.This work was supported by the Fundação para a Ciência e a Tecnologia (FCT), Portugal (SFRH/BPD/81627/2011 to SV), by iBB — Institute for Bioengineering and Biosciences — project UIDB/04565/2020, and by Egas Moniz Higher Institute of Health Science (Egas Moniz, CRL).

A Challenge Called Ogilvie´s Syndrome

Ogilvie´s syndrome is a colonic dilation without any existing mechanical obstruction. The risk factors that cause it are not completely understood, but if untreated, the distension can result in rupture or ischaemic bowel perforation. Additionally, the existing guidelines do not agree with each other about the next steps if conservative treatment fails. We report the case of a 71-year-old woman in whom Ogilvie´s syndrome was particularly difficult to manage, and with it, we try to add clinical data to a field with scarce evidence.info:eu-repo/semantics/publishedVersio

Phytochemical Composition of Extractives in the Inner Cork Layer of Cork Oaks with Low and Moderate Coraebus undatus Attack

The beetle Coraebus undatus, during its larval stage feeds, and excavates galleries on the cork-generating layer of Quercus suber L. trees, seriously affecting the cork quality with significant economic losses for the cork industry. This work compared the composition of the extracts present in the innermost cork layers (the belly) of cork planks from Q. suber trees with low and moderate C. undatus attack in one stand. The total extractives in the inner cork layer from trees with moderate and low C. undatus attacks were similar (on average 22% of the cork mass) with a high proportion of polar compounds (91% of the total extractives). The chemical composition of the inner cork lipophilic extractives was the same in trees infested and free of larvae, with triterpenes as the most abundant family accounting for 77% of all the compounds, predominantly friedeline. The hydrophilic extractives differed on the levels of phenolic compounds, with higher levels in the inner cork extracts of samples from trees with low attack (90.0 mg GAE g1 vs. 59.0 mg GAE g1 of inner cork mass) The potential toxic activity of phenolic compounds may have a role in decreasing the larval feedinginfo:eu-repo/semantics/publishedVersio

CONSEQUÊNCIAS DO PRODUTIVISMO ACADÊMICO PARA A VIDA DOCENTE

Este artigo é resultado de um estudo entre os professores do curso de Administração da Universidade Federal Fluminense (UFF) acerca da exigência de alta produtividade no setor acadêmico, caracterizada principalmente pelo aumento da quantidade de artigos científicos publicados sem ao menos considerar pesquisas mais aprofundadas, subestimando a qualidade. Entende-se tal prática como sendo de cunho produtivista. Este trabalho tem como objetivo verificar se os professores respondentes conseguem definir produtivismo acadêmico desta maneira e como eles percebem o impacto disto em suas aulas. Foi utilizado um questionário como instrumento de pesquisa. A pesquisa de campo é, portanto, o principal recurso metodológico usado. O tratamento dos dados será qualitativo, por meio da análise das respostas dadas, tomando como base a revisão da bibliografia sobre a temática. Conclui-se que a universidade é um ambiente de ensino e, portanto, não deve seguir a lógica do mercado, a qual tem impactado negativamente as aulas tanto de alunos da graduação, quanto da pós-graduação.Palavras-chave: Produtivismo acadêmico; Gerencialismo; Qualificação no trabalhodocente

Perfil Terapêutico da Hipertensão na Rede Médicos Sentinela - 12 Anos Depois

Objectivos: Determinar o perfil terapêutico da hipertensão arterial na Rede de Médicos Sentinela e comparar os resultados obtidos, 12 anos após a realização do primeiro estudo. Tipo de estudo: Estudo transversal. Local: Rede de Médicos Sentinela de Portugal. População: Doentes hipertensos com mais de 18 anos das listas dos médicos sentinela que se deslocaram à consulta entre 7 de Junho de 2010 e 31 de Dezembro de 2010. Métodos: Os médicos sentinela participantes recolheram informação dos doentes hipertensos, informação essa que contemplou a caracterização sociodemográfica, a caracterização da patologia (data de diagnóstico, forma de hipertensão, danos em órgão-alvo e morbilidade associada) e a caracterização da terapêutica instituída. Resultados: Foram incluídos 616 hipertensos no estudo. Comparativamente ao primeiro estudo (1998), verificou-se um ligeiro aumento da idade média dos participantes (62,0 anos em 1998 vs 64,3 anos em 2010), mantendo-se o predomínio do sexo feminino. A duração média da hipertensão desde o momento do diagnóstico aumentou significativamente (p < 0,0001). Aproximadamente metade dos hipertensos apresentou danos em órgãos-alvos em ambos os momentos, sendo a doença cardíaca o dano mais frequente. As patologias associadas mais frequentes foram a dislipidemia, a hiperuricemia e a diabetes. De 1998 para 2010, a proporção de doentes em monoterapia diminuiu (47,6% vs 30,3%), sendo os inibidores da enzima da conversão da angiotensina a classe terapêutica mais frequentemente prescrita em monoterapia nos dois momentos. Em 1998, o padrão de tratamento mais frequentemente prescrito foram inibidores da enzima da conversão da angiotensina em monoterapia (24,3%) e em 2010 foi a associação de antagonistas dos receptores da angiotensina + diuréticos tiazídicos (15,4%). Conclusões: Os fármacos que actuam no eixo renina-angiotensina-aldosterona foram, neste estudo, os mais frequentemente prescritos em ambos os momentos, tanto em monoterapia como em politerapia. O número de anti-hipertensores prescritos diferiu entre os dois momentos de acordo com a existência e tipo de comorbilidad
