    Mestrado em Actuarial ScienceNeste trabalho é feito o estudo da migração em Porto-Rico, tanto no curto como no longo, usando a análise de séries temporais e o processo estocástico de Ornstein Uhlenbeck. Os resultados mostram que, de acordo com a literatura, a migração é uma variável muito difícil de modelar. Apesar dessa dificuldade, mostra-se que a migração é uma variável que tem um impacto de longo prazo na economia, na demografia e na actividade seguradora de Porto-Rico. No final é dado um exemplo numérico com aplicações na actividade seguradora. São também apresentadas conclusões e perspectivas futuras para o estudo da migração em Porto-Rico.Migration in Puerto Rico is modeled, both in the short-term and long-term, using time series analysis and the Ornstein Uhlenbeck Stochastic Process. Results show that, in agreement with previous works, migration continues to be a very difficult and volatile variable to model. However, it is shown that contrary to most of the literature, migration is a variable that does have a long-term impact on Puerto Rico?s economy, demography, and actuarial industry.info:eu-repo/semantics/publishedVersio

    Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat
