Comparative StudyCause-specific long-term mortality rates in patients recovered from community-acquired pneumonia as compared with the general Dutch population.
Insights into long-term mortality, especially into the cause of death after initial recovery from an episode of community-acquired pneumonia (CAP), may help in determining optimal preventive measures in such patients. Prospective observational cohort studies were conducted to compare cause-specific long-term mortality rates for 356 patients who had recovered from CAP with those of the general Dutch population (16.3 million) between 2003 and 2007. The Dutch Municipal Public Records Database and death certificates were used to determine cause-specific mortality rates up to 7 years after discharge. ⋯ After initial recovery from an episode of CAP, long-term mortality rates are more than three times as high as in the general population. The causes of long-term mortality were mostly comorbidity-related, and significantly different from those in the general population. After an episode of CAP, optimization of treatment of comorbidities, such as treatment for COPD, might improve long-term survival rates.

Multicenter StudyFactors associated with severe disease in hospitalized adults with pandemic (H1N1) 2009 in Spain.
The risk factors for complications in patients with influenza A (H1N1)v virus infection have not been fully elucidated. We performed an observational analysis of a prospective cohort of hospitalized adults with confirmed pandemic influenza A (H1N1)v virus infection at 13 hospitals in Spain, between June 12 and November 10, 2009, to identify factors associated with severe disease. Severe disease was defined as the composite outcome of intensive-care unit (ICU) admission or in-hospital mortality. ⋯ Independent factors for severe disease were age <50 years (OR, 2.39; 95% CI, 1.05-5.47), chronic comorbid conditions (OR, 2.93; 95% CI, 1.41-6.09), morbid obesity (OR, 6.7; 95% CI, 2.25-20.19), concomitant and secondary bacterial co-infection (OR, 2.78; 95% CI, 1.11-7) and early oseltamivir therapy (OR, 0.32; 95% CI 0.16-0.63). In conclusion, although adults hospitalized for pandemic (H1N1) 2009 suffer from significant morbidity, mortality is lower than that reported in the earliest studies. Younger age, chronic comorbid conditions, morbid obesity and bacterial co-infection are independent risk factors for severe disease, whereas early oseltamivir therapy is a protective factor.
