Pequenas cidades históricas e seus visitantes: aplicação a uma cidade histórica do Norte de Portuga

A caracterização da procura turística de uma determinada localidade é uma temática relevante, tanto para a análise da atual situação da atividade turística quanto para o seu planeamento e desenvolvimento. Este artigo tem como objetivo geral descrever o perfil do visitante de pequenas cidades históricas, bem como a opinião destes acerca da gestão patrimonial efetuada. O estudo foi aplicado a uma cidade histórica do norte de Portugal (Lamego) que integra a delimitação do Douro Património da Humanidade. Em termos metodológicos, foi usada uma abordagem quantitativa, através da realização de uma inquirição por questionário aplicado a 339 visitantes desta cidade histórica. Os resultados permitiram obter um melhor conhecimento dos visitantes em termos de perfil sociodemográfico, do produto consumido, da gestão e experiência turística e do tipo de viagem. Este conhecimento revela‑se indispensável para adequar a oferta à procura numa visão de desenvolvimento sustentável, sendo útil para as diversas partes interessadas (stakeholders) deste destino turístico.

Chronic sustained hypoxia-induced redox remodeling causes contractile dysfunction in mouse sternohyoid muscle

Chronic sustained hypoxia (CH) induces structural and functional adaptations in respiratory muscles of animal models, however the underlying molecular mechanisms are unclear. This study explores the putative role of CH-induced redox remodeling in a translational mouse model, with a focus on the sternohyoid—a representative upper airway dilator muscle involved in the control of pharyngeal airway caliber. We hypothesized that exposure to CH induces redox disturbance in mouse sternohyoid muscle in a time-dependent manner affecting metabolic capacity and contractile performance. C57Bl6/J mice were exposed to normoxia or normobaric CH (FiO2 = 0.1) for 1, 3, or 6 weeks. A second cohort of animals was exposed to CH for 6 weeks with and without antioxidant supplementation (tempol or N-acetyl cysteine in the drinking water). Following CH exposure, we performed 2D redox proteomics with mass spectrometry, metabolic enzyme activity assays, and cell-signaling assays. Additionally, we assessed isotonic contractile and endurance properties ex vivo. Temporal changes in protein oxidation and glycolytic enzyme activities were observed. Redox modulation of sternohyoid muscle proteins key to contraction, metabolism and cellular homeostasis was identified. There was no change in redox-sensitive proteasome activity or HIF-1α content, but CH decreased phospho-JNK content independent of antioxidant supplementation. CH was detrimental to sternohyoid force- and power-generating capacity and this was prevented by chronic antioxidant supplementation. We conclude that CH causes upper airway dilator muscle dysfunction due to redox modulation of proteins key to function and homeostasis. Such changes could serve to further disrupt respiratory homeostasis in diseases characterized by CH such as chronic obstructive pulmonary disease. Antioxidants may have potential use as an adjunctive therapy in hypoxic respiratory disease.

Avaliação do nível de conhecimento geral e grau de alerta sobre cancro oral numa população do nordeste transmontano

O cancro é um dos principais causadores de milhões de mortes em todo o mundo e sendo o cancro oral, especificamente, a sexta neoplasia mais frequente a nível mundial. Todos os anos são diagnosticados mais de 500 mil novos casos, sendo que as altas taxas de mortalidade e mortalidade não se têm alterado ao longo dos anos. A maior incidência de cancro oral encontra-se na Ásia e na Europa do Sul. Em Portugal, mais precisamente em 2012, foram diagnosticados cerca de 1924 novos casos de cancro oral, dos quais 967 ocorreram em homens. O carcinoma espinocelular é o tipo histológico mais comum, sendo que 90% dos casos de cancro oral são deste tipo. Sabe-se também que esta variante é mais frequente no sexo masculino entre a 5ª e 6 ª década de vida apesar de, a incidência no sexo feminino, ter vindo a aumentar, devido à contínua exposição ao tabaco, álcool e a outros factores de risco. Como foi dito anteriormente, o cancro oral tem uma alta taxa de mortalidade e de morbilidade e, apesar dos avanços no diagnóstico, no tratamento e no conhecimento de quais os factores de risco desta patologia, a taxa de sobrevivência ainda é inferior a 50% o que revela que, o grande problema, passa pelo diagnóstico do cancro em estádios avançados. Assume-se então que, grande parte dos casos de cancro oral, poderiam ter sido evitados se houvesse maior conhecimento e grau de alerta sobre a doença o que tendencialmente, levaria a diagnósticos mais precoces. Neste sentido, este estudo tem como propósito a avaliação do nível de conhecimento geral e do grau de alerta de uma população do interior do país, mais precisamente do Nordeste Transmontano, bem como, efectuar o registo da percepção dos inquiridos relativamente a esta patologia, passando pelo reconhecimento da doença, pelo conhecimento epidemiológico e etiológico, e pela melhor percepção a nível de sinais e sintomas clínicos próprios desta patologia.

Outpatient follow-up during the first year after heart transplantation, is it feasible?

First year follow-up after heart transplantation requires invasive tests. Although patients used to be hospitalized for this purpose, ambulatory invasive procedures now offer the possibility of outpatient follow-up. The feasibility and security of this strategy is unknown. From 2007 we transitioned to outpatient follow-up. We have retrospectively reviewed the clinical course of the outpatient group (2007 to 2014) and an inpatient group (2000–2006). Basal characteristics, hospital stay, infections, rejection episodes and vascular complications were evaluated. 87 patients had Inpatient Follow-up (IF) and 98 Outpatient Follow-up (OF). Basal characteristics were similar, with significant differences in immunosuppression (tacrolimus IF 44.8% vs. OF 90.8%, and mycophenolate IF 86.2% vs OF 100%, both p values < 0.001) and age (IF 52 ± 11.5 years vs. OF 56.1 ± 11 years, p = 0.016). In the OF group more clinical visits were performed (IF 10 vs. OF 13, p < 0.001) while hospital stay was lower (IF 23 days vs. OF 3 days, p < 0.001). The rate of infection, rejection, and vascular complications was similar. No difference was found in 1-year mortality (IF 2.3% vs. 1.0%, p = 0.60). First year post-cardiac transplantation outpatient follow-up seems to be feasible and safe in terms of infection, rejection, vascular complications and mortality.

Incidence and clinical impact of infective endocarditis after transcatheter aortic valve implantation

The aim of this study is to describe the characteristics of infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI). This study was performed using the GAMES database, a national prospective registry of consecutive patients with IE in 26 Spanish hospitals. Of the 739 cases of IE diagnosed during the study, 1.3% were post-TAVI IE, and these 10 cases, contributed by five centres, represented 1.1% of the 952 TAVIs performed. Mean age was 80 years. All valves were implanted transfemorally. IE appeared a median of 139 days after implantation. The mean age-adjusted Charlson comorbidity index was 5.45. Chronic kidney disease was frequent (five patients), as were atrial fibrillation (five patients), chronic obstructive pulmonary disease (four patients), and ischaemic heart disease (four patients). Six patients presented aortic valve involvement, and four only mitral valve involvement; the latter group had a higher percentage of prosthetic mitral valves (0% vs. 50%). Vegetations were found in seven cases, and four presented embolism. One patient underwent surgery. Five patients died during follow-up: two of these patients died during the admission in which the valve was implanted. Conclusions: IE is a rare but severe complication after TAVI which affects about 1% of patients and entails a relatively high mortality rate. IE occurred during the first year in nine of the 10 patients.

Very low risk ST-segment elevation myocardial infarction? It exists and may be easily identified

Early discharge protocols have been proposed for ST-segment elevation myocardial infarction (STEMI) low risk patients despite the existence of few but significant cardiovascular events during mid-term follow-up. We aimed to identify a subgroup of patients among those considered low-risk in which prognosis would be particularly good. We analyzed 30-day outcomes and long-term follow-up among 1.111 STEMI patients treated with reperfusion therapy. Multivariate analysis identified seven variables as predictors of 30-day outcomes: Femoral approach; age > 65; systolic dysfunction; postprocedural TIMI flow < 3; elevated creatinine level > 1.5 mg/dL; stenosis of left-main coronary artery; and two or higher Killip class (FASTEST). A total of 228 patients (20.5%), defined as very low-risk (VLR), had none of these variables on admission. VLR group of patients compared to non-VLR patients had lower in-hospital (0% vs. 5.9%; p < 0.001) and 30-day mortality (0% vs. 6.25%: p < 0.001). They also presented fewer in-hospital complications (6.6% vs. 39.7%; p < 0.001) and 30-day major adverse events (0.9% vs. 4.5%; p = 0.01). Significant mortality differences during a mean follow-up of 23.8 ± 19.4 months were also observed (2.2% vs. 15.2%; p < 0.001). The first VLR subject died 11 months after hospital discharge. No cardiovascular deaths were identified in this subgroup of patients during follow-up. About a fifth of STEMI patients have VLR and can be easily identified. They have an excellent prognosis suggesting that 24–48 h in-hospital stay could be a feasible alternative in these patients.
