- Association between living setting and malnutrition among older adults: The PEN-3S studyPublication . Madeira, Teresa; Peixoto-Plácido, Catarina; Sousa-Santos, Nuno; Santos, Osvaldo; Costa, Joana; Alarcão, Violeta; Nicola, Paulo Jorge; Severo, Milton; Lopes, Carla; Clara, João GorjãoObjectives: Malnutrition is frequent among older adults, especially those living in nursing homes, but the association between residential setting and nutritional status is controversial. The aim of this study was to examine the association between living setting (nursing home versus community) and malnutrition while adjusting for demographic, socioeconomic, health-related, and psychosocial factors. Methods: This cross-sectional study included a randomly selected representative sample of Portuguese adults ≥65 y of age. Interviewers collected data regarding demographic and socioeconomic characteristics, nutritional status, physical activity, energy intake, cognitive function, self-reported general health, functional status, symptoms of depression, and loneliness. Logistic regression models were used to estimate the association between residential setting and malnutrition. Results: Participants were 1186 nursing home residents (72.8% women, 49.2% ≥85 y of age) and 1120 community dwellers (49% women, 21.3% ≥85 y of age). Following Mini Nutritional Assessment (MNA®) criteria, 29.6% of nursing home residents and 14.1% of community dwellers were at risk of malnutrition, whereas 2.3% and 0.3%, respectively, were malnourished. The living setting was not significantly associated with malnutrition after adjusting for functional status, symptoms of depression, and feelings of loneliness (odds ratio, 1.03; 95% confidence interval, 0.67–1.58). Conclusions: Risk of malnutrition and malnutrition are more prevalent among nursing home residents than community dwellers. Physical (functional status) and mental health (symptoms of depression and loneliness) seems more relevant to nutritional status than residential setting by itself. These findings should be taken into account when designing public health policies to tackle malnutrition among older adults.
- Attitude Towards Pressure Ulcers Instrument: validação e adaptação transcultural para a população portuguesa de enfermeirosPublication . Batista, Margarida; Dixe, Maria dos Anjos; Alves, PauloContexto/objetivos: A investigação e a prática têm evidenciado a importância das atitudes dos enfermeiros na prevenção das úlceras de pressão e a necessidade da elaboração de instrumentos de medida válidos e fiáveis para a sua avaliação. Respondendo a esta necessidade, procedemos à validação transcultural do Attitude Towards Pressure Ulcers Instrument (APU) para a população portuguesa. Metodologia: Realizou-se um estudo metodológico numa amostra não-probabilística de estudantes de enfermagem (n=147) e enfermeiros (n=155). Foi utilizada a metodologia usada no estudo de validação original. Resultados: A tradução-retrotradução com a participação de um painel de peritos garantiu a equivalência semântica e conceptual. A análise fatorial determinou que os 22 itens se organizam em 5 fatores (importância, responsabilidade, obstáculos/barreiras, confiança na eficácia e competências pessoais), explicando 53,6% da variância total. Obteve-se um poder descriminante da escala em alguns dos grupos comparados. O coeficiente a Cronbach total=0,847 garantiu a consistência interna da escala e a confiabilidade teste-reteste revelou coeficientes de correlação r=0,883 comprovando a sua estabilidade temporal. Enfermeiros e estudantes revelaram uma atitude positiva acerca dos itens da escala, sem diferença estatisticamente significativa entre estes (t=0,567; p>0,05). Conclusão: A escala APu-PT evidenciou ser fiável e válida para a prática, ensino e investigação.
- Effects of Anaesthesia on Insulin Sensitivity and Metabolic Parameters in Wistar RatsPublication . Guarino, Maria Pedro; Santos, Ana Isabel; Mota-Carmo, Miguel; Costa, Pedro FreireWe compared the effects of two different anaesthetics, sodium pentobarbital (65 mg/kg) and ketamine (30 mg/kg) plus xylazine (4 mg/kg) (KX) on insulin sensitivity, fasting glycaemia, insulinaemia and free fatty acids (FFA). Four groups of Wistar rats were used: KX group (n=6), pentobarbital group (n=6), high-sucrose diet group (n=6) and the conscious group (n=6). The insulin tolerance test (ITT) was used to measure insulin sensitivity, and metabolic biomarkers were determined using commercial kits. Pentobarbital did not alter plasma insulin, glucose, FFA or the ITT results compared to conscious animals. In contrast, KX anaesthesia induced hyperglycaemia, increased serum FFA and altered the ITT results compared to the conscious animal group. Moreover, under pentobarbital anaesthesia, the ITT proved to be a suitable method to detect insulin resistance in an animal model of diet-induced insulin resistance. We concluded that sodium pentobarbital anaesthesia should be used in metabolic studies since it does not interfere with plasma glucose, insulin, F FA or insulin sensitivity quantification in Wistar rats.
- HIV/AIDS length of stay in Portugal under financial constraints: a longitudinal study for public hospitals, 2009–2014Publication . Augusto, Gonçalo; Abrantes, Alexandre V.; Martins, Maria R.; Dias, SaraThe global financial crisis and the economic and financial adjustment programme (EFAP) forced the Portuguese government to adopt austerity measures, which also included the health sector. The aim of this study was to analyse factors associated with HIV/AIDS patients' length of stay (LOS) among Portuguese hospitals, and the potential impact of the EFAP measures on hospitalizations among HIV/AIDS patients. METHODS: Data used in this analysis were collected from the Portuguese database of Diagnosis Related Groups (DRG). We considered only discharges classified under MCD 24 created for patients with HIV infection. A total of 20,361 hospitalizations occurring between 2009 and 2014 in 41 public hospitals were included in the analysis. The outcome was the number of days between hospital admission and discharge dates (LOS). Hierarchical Poisson regression model with random effects was used to analyse the relation between LOS and patient, treatment and setting characteristics. To more effectively analyse the impact of the EFAP implementation on HIV/AIDS hospitalizations, yearly variables, as well as a variable measuring hospitals' financial situation (current ratio) was included. RESULTS: For the 5% level, having HIV/AIDS as the principal diagnosis, the number of secondary diagnoses, the number of procedures, and having tuberculosis have a positive impact in HIV/AIDS LOS; while being female, urgent admission, in-hospital mortality, pneumocystis pneumonia, hepatitis C, and hospital's current ratio contribute to the decrease of LOS. Additionally, LOS between 2010 and 2014 was significantly shorter in comparison to 2009. Differences in LOS across hospitals are significant after controlling for these variables. CONCLUSION: Following the EFAP, a number of cost-containment measures in the health sector were implemented. Results from our analysis suggest that the implementation of these measures contributed to a significant decrease is LOS among HIV/AIDS patients in Portuguese hospitals

- Late-Night Salivary Cortisol: Cut-Off Definition and Diagnostic Accuracy for Cushing’s Syndrome in a Portuguese PopulationPublication . Lages, Adriana De Sousa; Oliveira, Diana; Paiva , Isabel; Oliveira, Patrícia; Rebelo-Marques, Alexandre; Carrilho, Francisco; Frade, João Gonçalo Leal de Oliveira e SilvaIntroduction: Diagnosis of Cushing’s syndrome remains a challenge in clinical endocrinology. Even though late-night salivary cortisol is used as screening tool, individualized cut-off levels for each population must be defined.Material and Methods: Three groups of subjects were studied: normal subjects, suspected and proven Cushing’s syndrome. Salivary cortisol was measured using an automated electrochemiluminescence assay. The functional sensitivity of the assay is 0.018 μg/dL. The diagnostic cut-off level was defined by Receiver Operating Characteristic curve and Youden’s J index.Results: We studied 127 subjects: 57 healthy volunteers, 39 patients with suspected and 31 with proven Cushing’s syndrome. 2.5th- 97.5th percentile of the late-night salivary cortisol concentrations in normal subjects was 0.054 to 0.1827 μg/dL. Receiver Operating Characteristic curve analysis showed an area under the curve of 0.9881 (p < 0.0001). A cut-off point of 0.1 μg/dL provided a sensitivity of 96.77% (95% CI 83.3 - 99.92%) and specificity of 91.23% (95% CI 80.7 - 97.09%). There was a significant correlation between late-night salivary cortisol and late-night serum cortisol (R = 0.6977; p < 0.0001) and urinary free cortisol (R = 0.5404; p = 0.0025) in proven Cushing’s syndrome group.Discussion: The mean ± SD late-night salivary cortisol concentration in patients with proven Cushing’s syndrome (0.6798 ± 0.52 μg/dL) was significantly higher (p < 0.0001). In our population, the late-night salivary cortisol cut-off was 0.1 μg/dL with high sensitivity and specificity.Conclusion: Late-night salivary cortisol has excellent diagnostic accuracy, making it a highly reliable, noninvasive, screening tool for outpatient assessment. Given its convenience and diagnostic accuracy, late-night salivary cortisol may be added to other traditional screening tests on hypercortisolism
- O lugar da investigação participada de base comunitária na promoção da saúde mentalPublication . Gomes, José Carlos Rodrigues; Loureiro, Maria Isabel GuedesA saúde mental é imprescindível ao desenvolvimento social e económico das comunidades. Envolver as comunidades no desenho e desenvolvimento de planos locais de promoção da saúde mental é um importante desafio para garantir mais e melhor saúde mental a cada comunidade. De 2009 a 2012 desenvolveu-se um estudo de caso baseado nos pressupostos de uma investigação participada de base comunitária numa comunidade urbana da região metropolitana de Lisboa, com o objetivo de fundamentar o desenho de um plano local de promoção da saúde mental local. O resultado deste trabalho de parceria, que envolveu habitantes e organizações governamentais e não-governamentais da comunidade urbana, fundamentado na capacitação individual e comunitária da comunidade e dos seus membros, confirmou a necessidade de uma participação ativa e efetiva da comunidade no desenvolvimento de políticas locais de promoção da saúde e concluiu pela definição de 6 eixos estratégicos de intervenção pelo período temporal 2012/2015: uma escola com saúde mental; uma comunidade ativa e segura; uma comunidade solidária e inclusiva; uma comunidade atenta; uma organização económico-laboral promotora de saúde mental; uma senioridade mentalmente saudável.
- Optimization of heart failure with reduced ejection fraction prognosis-modifying drugs: A 2021 heart failure expert consensus paperPublication . Silva-Cardoso, José; Fonseca, Cândida; Franco Fátima; Morais, João; Ferreira, Jorge; Brito, DulceHeart failure (HF) with reduced ejection fraction (HFrEF) is associated with high rates of hospitalization and death. It also has a negative impact on patients’ functional capacity and quality of life, as well as on healthcare costs. In recent years, new HFrEF prognosis-modifying drugs have emerged, leading to intense debate within the international scientific community toward a paradigm shift for the management of HFrEF. In this article, we report the contribution of a Portuguese HF expert panel to the ongoing debate. Based on the most recently published clinical evidence, and the panel members’ clinical judgment, three key principles are highlighted: (i) sacubitril/valsartan should be preferred as first-line therapy for HFrEF, instead of an angiotensin-converting enzyme inhibitor or angiotensin receptor blocker; (ii) the four foundation HFrEF drugs are the angiotensin receptor/neprilysin inhibitor, beta-adrenergic blocking agents, mineralocorticoid receptor antagonists, and sodium-glucose co-transporter 2 inhibitors, regardless of the presence of type-2 diabetes mellitus; (iii) these four HFrEF drug classes should be introduced over a short-term period of four to six weeks, guided by a safety protocol, followed by a dose up-titration period of 8 weeks.
- Programas de educação dirigidos ao utente com diabetes mellitus tipo 2: revisão sistemática da literaturaPublication . Menino, Eva; Dixe, Maria dos Anjos; Martins Louro, Maria Clarisse; Roque, SofiaO aumento da longevidade e as problemáticas de saúde associadas ao aumento da incidência da doença crónica, concretamente a diabetes que apresenta implicações documentadas ao nível económico, social e familiar, justificam a necessidade de uma resposta dos serviços de saúde consertada e de qualidade. Esta revisão sistemática tem como objetivo analisar os programas de educação dirigidos ao utente diabético, metodologias de avaliação assim como os respetivos resultados. Os cinco estudos incluídos resultaram duma pesquisa realizada na EBSCOhost e na ISI Web of Knowledge. Os programas de intervenção apresentam metodologias e estruturas distintas, embora todos tenham tido por base teórica a educação para a autogestão. As metodologias de avaliação da eficácia dos programas incidiram essencialmente em parâmetros fisiológicos, embora em alguns estudos tenham sido avaliados parâmetros psicológicos. Os resultados mostram melhorias nos valores da Hemoglobina glicada; da pressão arterial, colesterol, na vigilância oftálmica, autovigilância dos pés e vigilância nefropática, autoeficácia, qualidade de vida, dieta, peso corporal, perímetro abdominal, indicadores de atitude e indicadores de comportamento. Parece haver uma resposta positiva aos programas de intervenção, traduzida em resultados relacionados com parâmetros fisiológicos e parâmetros psicológicos.
- Proposal of an integrated decision support system for Tuberculosis based on Semantic WebPublication . Lima, Vinícius; Pellison, Felipe; Bernardi, Filipe; Carvalho, Isabelle; Alves, Domingos; Rijo, Rui Pedro Charters LopesEpidemiological surveillance of Tuberculosis (TB) requires a strong integration of different health services, programs and levels of care. The deepening and broadening of data management techniques must be constantly carried out to increase the integrality of healthcare. Otherwise, knowledge extraction and clinical and administrative decision-making processes are significantly hampered, directly affecting the management and quality of health services. Thus, this work aims to establish a computerized decision support system capable of collecting, integrating and sharing TB health data in Brazilian Unified Public Health System. Also, it will allow the monitoring of infected patients and the visualization of consolidated information of regular TB and its resistant variants for health professionals and managers. The data will be made available from heterogeneous, disconnected and unstructured sources by combining traditional web services, Semantic Web resources and security algorithms. A solid knowledge base applied to epidemiological surveillance, health information governance and clinical support will be enabled to integrate the multiple areas of TB patients care, as well as to support the creation of more accurate operational and diagnostics models
