Background: Evidence evaluating the risk of pneumonia in patients with obstructive sleep apnea is limited and mostly focuses on patients who receive continuous positive airway pressure (CPAP) therapy or on pediatric patients. We aimed to explore the risk of incident pneumonia among adults with sleep apnea, either with or without the need of CPAP therapy. Methods: From Jan. 1, 2000, we identified adult patients with sleep apnea from the Taiwan National Health Insurance Research Database. A control cohort without sleep apnea, matched for age, sex and comorbidities, was selected for comparison. The 2 cohorts were followed until Dec. 31, 2010, and observed for occurrence of pneumonia. Results: Of the 34 100 patients (6816 study patients and 27 284 matched controls), 2757 (8.09%) had pneumonia during a mean follow-up period of 4.50 years, including 638 (9.36%) study patients and 2119 (7.77%) controls. Kaplan–Meier analysis showed a higher incidence of pneumonia among patients with sleep apnea (log rank test, p < 0.001). After multivariate adjustment, patients with sleep apnea experienced a 1.20-fold (95% confidence interval 1.10–1.31) increase in incident pneumonia. The risk was even higher among patients who received CPAP therapy. Interpretation: Sleep apnea appeared to confer a higher risk for future pneumonia, possibly in a severity-dependent manner.

Rationale: Intensive care unit (ICU)-acquired weakness is a common issue for sepsis survivors that is characterized by impaired muscle strength and causes functional disability. Although inpatient rehabilitation has not been found to reduce in-hospital mortality, the impact of postdischarge rehabilitation on sepsis survivors is uncertain. Objectives: To investigate the benefit of postdischarge rehabilitation to long-term mortality in sepsis survivors. Methods: We conducted a nationwide, population-based, high-dimensional propensity score–matched cohort study using Taiwan’s National Health Insurance Research Database. The rehabilitation cohort comprised 15,535 ICU patients who survived sepsis and received rehabilitation within 3 months after discharge between 2000 and 2010. The control cohort consisted of 15,535 high-dimensional propensity score–matched subjects who did not receive rehabilitation within 3 months after discharge. The endpoint was mortality during the 10-year follow-up period. Measurements and Main Results: Compared with the control cohort, the rehabilitation cohort had a significantly lower risk of 10-year mortality (adjusted hazard ratio, 0.94; 95% confidence interval, 0.92–0.97; P < 0.001), with an absolute risk reduction of 1.4 per 100 person-years. The frequency of rehabilitation was inversely associated with 10-year mortality (≥3 vs. 1 course: adjusted hazard ratio, 0.82; P < 0.001). Compared with the control cohort, improved survival was observed in the rehabilitation cohort among ill patients who had more comorbidities, required more prolonged mechanical ventilation, and had longer ICU or hospital stays, but not among those with the opposite conditions (i.e., less ill patients). Conclusions: Postdischarge rehabilitation may be associated with a reduced risk of 10-year mortality in the subset of patients with particularly long ICU courses.
Background. Epidemiological studies have shown a strong association between systemic inflammatory diseases, particularly allergic diseases, and cardiovascular diseases. However, the relationship between atopic dermatitis (AD) and ischemic stroke remains unclear. Method. The study identified 20,323 AD patients and 20,323 comorbidity-matched subjects between 2005 and 2008. The two cohorts were followed until 31 December 2009. Ischemic stroke and other cardiovascular events were determined. Results. During the follow-up period, 301 (1.48%) patients in the AD cohort and 228 (1.12%) matched subjects experienced ischemic stroke. After multivariate adjustment, patients with AD had a 1.33-fold (95% confidence interval (CI), 1.12–1.59; P = 0.001) increased incidence of ischemic stroke. Adjusted hazard ratios for the risk of ischemic stroke in patients with mild, moderate, and severe AD were 1.20 (95% CI, 1.00–1.45; P = 0.052), 1.64 (95% CI, 1.23–2.19; P = 0.001), and 1.71 (95% CI, 1.15–2.56; P = 0.008), respectively. The log-rank test showed a higher cumulative incidence of ischemic stroke in the severe AD group than in the moderate and mild AD groups during the follow-up period (P < 0.001). Conclusions. AD may be an independent risk factor for ischemic stroke, and risk of ischemic stroke increases with AD severity.
