- Predictors of de novo atrial fibrillation in a non-cardiac intensive care unitPublication . Augusto, JB; Fernandes, A; Telles de Freitas, P; Gil, V; Morais, COBJECTIVE: To assess the predictors of de novo atrial fibrillation in patients in a non-cardiac intensive care unit. METHODS: A total of 418 hospitalized patients were analyzed between January and September 2016 in a non-cardiac intensive care unit. Clinical characteristics, interventions, and biochemical markers were recorded during hospitalization. In-hospital mortality and length of hospital stay in the intensive care unit were also evaluated. RESULTS: A total of 310 patients were included. The mean age of the patients was 61.0 ± 18.3 years, 49.4% were male, and 23.5% presented de novo atrial fibrillation. The multivariate model identified previous stroke (OR = 10.09; p = 0.016) and elevated levels of pro-B type natriuretic peptide (proBNP, OR = 1.28 for each 1,000pg/mL increment; p = 0.004) as independent predictors of de novo atrial fibrillation. Analysis of the proBNP receiver operating characteristic curve for prediction of de novo atrial fibrillation revealed an area under the curve of 0.816 (p < 0.001), with a sensitivity of 65.2% and a specificity of 82% for proBNP > 5,666pg/mL. There were no differences in mortality (p = 0.370), but the lengths of hospital stay (p = 0.002) and stay in the intensive care unit (p = 0.031) were higher in patients with de novo atrial fibrillation. CONCLUSIONS: A history of previous stroke and elevated proBNP during hospitalization were independent predictors of de novo atrial fibrillation in the polyvalent intensive care unit. The proBNP is a useful and easy- and quick-access tool in the stratification of atrial fibrillation risk.

- Fifteen years of coronary intravascular ultrasound in percutaneous coronary intervention in PortugalPublication . Azevedo Guerreiro, R; Fernandes, R; Campante Teles, R; Canas da Silva, P; Pereira, H; Cruz Ferreira, R; Costa, M; Seixo, F; Farto E Abreu, P; Pipa, JL; Bernardes, L; Pereira Machado, F; Palos, J; Infante de Oliveira, E; Cyrne Carvalho, H; Silva, JC; Caires, G; Martins, D; Baptista, J; Calisto, J; Pontes Dos Santos, R; Matias, F; Costa, J; Sousa, P; Gama Ribeiro, V; Fiarresga, A; Brum da Silveira, JINTRODUCTION: Coronary intravascular ultrasound (IVUS) is increasingly important in catheterization laboratories due to its positive prognostic impact. This study aims to characterize the use of IVUS in percutaneous coronary intervention (PCI) in Portugal. METHODS: A retrospective observational study was performed based on the Portuguese Registry on Interventional Cardiology of the Portuguese Society of Cardiology. The clinical and angiographic profiles of patients who underwent PCI between 2002 and 2016, the percentage of IVUS use, and the coronary arteries assessed were characterized. RESULTS: A total of 118 706 PCIs were included, in which IVUS was used in 2266 (1.9%). Over time, use of IVUS changed from none in 2002 to generally increasing use from 2003 (0.1%) to 2016 (2.4%). The age of patients in whom coronary IVUS was used was similar to that of patients in whom IVUS was not used, but in the former group there were fewer male patients, and a higher prevalence of cardiovascular risk factors (hypertension, hypercholesterolemia and diabetes), previous myocardial infarction, previous PCI, multivessel coronary disease, C-type or bifurcated coronary lesions, and in-stent restenosis. IVUS was used in 54.8% of elective PCIs and in 19.15% of PCIs of the left main coronary artery. CONCLUSION: Coronary IVUS has been increasingly used in Portugal since 2003. It is used preferentially in elective PCIs, and in patients with higher cardiovascular risk, with more complex coronary lesions and lesions of the left main coronary artery.

- Portuguese recommendations for the use of ultrasound in rheumatologyPublication . Polido-Pereira, J; Serra, S; Teixeira, F; Ponte, C; Cerqueira, M; Cruz, M; Araújo, F; Barros, R; Costa, T; Santos-Faria, D; Lopes, C; Madruga-Dias, J; Oliveira, M; Teixeira, R; Vilar, A; Falcão, S; Saraiva, F; Figueiredo, GNTRODUCTION: Ultrasound (US) is a relatively cheap, easily available and reliable method to improve the care of rheumatic patients. However, its use in rheumatology practice is very heterogeneous and needs to be standardized. OBJECTIVES: To develop recommendations for the use of US in rheumatic diseases endorsed by the Portuguese Society of Rheumatology. METHODS: A systematic literature review of the available recommendations on the use of ultrasound in rheumatic diseases was performed and presented in a Portuguese Society of Rheumatology meeting to a subgroup of rheumatologists and rheumatology trainees with special interest in the subject. The most important topics to be addressed were selected and assigned to subgroups for literature review and draft recommendations. Following an iterative process of consensus, the final recommendations were developed, and their level of agreement voted anonymously online. A recommendation was approved when the average level of agreement was ≥ 7.5 in a 10-point Likert scale. RESULTS: Fourteen recommendations were produced regarding nine rheumatology topics: rheumatoid arthritis, spondyloarthritis, connective tissue diseases, polymyalgia rheumatica, vasculitis, crystal-deposition diseases, soft tissue rheumatism, osteoarthritis and ultrasound-guided procedures. CONCLUSION: We developed an up-to-date guidance in the form of recommendations for the use of US in nine different areas of rheumatology. As ultrasound is an important imaging modality with increasing use in the rheumatology setting, and there are frequent technological advances in the ultrasound machines and probes, in parallel with continuous associated research, these recommendations should be regularly updated.
