- Clinicoepidemiological profile of cerebral venous thrombosis in Algarve, Portugal: a retrospective observational studyPublication . Nzwalo, Hipólito; Rodrigues, Fatima; Carneiro, Patricia; Macedo, Ana; Ferreira, Fatima; Basilio, CarlosBackground: Cerebral venous thrombosis (CVT) is a very uncommon disorder with a wide variety of clinical manifestations. There are few studies describing the clinical and epidemiological profile of CVT in peripheral or rural areas. Over the last decades, the frequency in which this disease is diagnosed has increased due to greater awareness and availability of noninvasive diagnostic techniques. Materials and Methods: A hospital-based retrospective case review of adult (>= 15 years) patients with CVT between 2001 and 2012 is described. 31 patients with confirmed imagiological diagnosis of CVT were included. Statistical Analysis Used: Statistical analysis was performed using R version 2.15.2. Incidence rate was computed as number of new cases by time. Confidence interval (CI) was set at 95% and P < 0.05 was considered significant. Results: The average annual incidence was 0.84 (CI: 0.58-1.18) to 0.73 (CI: 0.5-1.02) per 100 000 cases for adult population. There were 23 (74%) women and 8 (26%) men. Predominant initial manifestations were headache, followed by altered mental status and seizures. Median diagnostic delay from onset of illness was 8 days. All patients were treated with unfractionated heparin or low-molecular heparin followed by warfarin. Complete recovery occurred in the majority of cases 22 (78.6%) but two patients died during hospitalization. Conclusions: Albeit with some particularities, the epidemiology and clinical manifestations we found are comparable to what has been reported in western studies.
- Mortality predictive factors in subjects with COPD after a pulmonary rehabilitation program: A 3-year studyPublication . Saraiva, Catia; Abreu, Tiago; Neves, Djamila; Rodrigues, FatimaBACKGROUND: COPD is a high-mortality disease and projected to become the third leading cause of death worldwide by 2030. Our aim was to evaluate predictors of 3-y mortality and factors associated with early (1 y) and late (second and third year) mortality in subjects with severe COPD who completed a pulmonary rehabilitation program. METHODS: A historical cohort study was performed with subjects with COPD who were admitted to a day-hospital for chronic respiratory failure for a pulmonary rehabilitation program, from January 2008 to December 2010. The population was characterized based on sociodemographic factors, body mass index, smoking habits, lung function tests, respiratory failure, comorbidities, bacterial colonization, Modified Medical Research Council dyspnea index, 6-min walk test, mechanical ventilation, noninvasive ventilation, long-term oxygen therapy, hospital admissions, and mortality. RESULTS: From 183 patients who completed a pulmonary rehabilitation program, 93 had COPD. Our cohort had 78 male and 15 female subjects. The mean age +/- SD was 68.6 +/- 8.9 y, ranging from 43 to 85 y. After the pulmonary rehabilitation program, there were fewer, although not statistically significantly different hospital admissions (2.1 vs 1.7, P =.17). Three years after the pulmonary rehabilitation program, 34 subjects died (36.6%). Hypercapnic respiratory failure (P = .02), noninvasive ventilation (P = .002), lung cancer (P = .001), shorter 6-min walk distance (P = .03), and higher number of previous hospital admissions (P <.001) were associated with a higher mortality rate. CONCLUSION: There is a high mortality rate in late-stage patients with COPD. The most relevant factors associated with mortality were lung cancer, respiratory failure and noninvasive ventilation, severe exacerbations with hospitalization, and lower functional exercise capacity.
