Asian population-based data evaluating all-cause mortality and cause-specific mortality in patients with psoriasis are limited. This study aimed to evaluate the risk of all-cause mortality (stratified according to onset status, disease severity, and concomitant psoriatic arthritis) and cause-specific mortality in patients with psoriasis. Our study cohort consisted of 80,167 patients with newly diagnosed psoriasis between 2001 and 2012 in the National Health Insurance Database. Vital status and cause of death were ascertained from the National Death Registry of Taiwan. All-cause and cause-specific crude mortality rates and standardized mortality ratios were estimated. A total of 7,198 deaths were identified during the follow-up period (508,505 person-years). The standardized mortality ratios were 1.53 for severe psoriasis (95% confidence interval = 1.45-1.60), 1.47 for early-onset psoriasis (95% confidence interval = 1.34-1.61), and 1.47 for patients with psoriatic arthritis (95% confidence interval = 1.36-1.58). In the cause-specific mortality analysis, the absolute and excess risks of death were highest for malignancies (3.6 and 1.57 deaths per 1,000 patient-years, respectively) and circulatory system diseases (3.0 and 1.44 deaths per 1,000 patient-years, respectively). Patients with severe psoriasis, early-onset psoriasis, and psoriatic arthritis had higher all-cause mortality risks. In particular, patients with psoriasis had higher excess risks of mortality from malignancies and circulatory system diseases.

Psoriasis carries an elevated risk of NMSC and lymphoma. This effect is modified by the severity of psoriasis, age, gender, and geographic location.

IntroductionTheoretically, high-frequency oscillatory ventilation (HFOV) achieves all goals of a lung-protective ventilatory mode and seems ideal for the treatment of adult patients with acute respiratory distress syndrome (ARDS). However, its effects on mortality and adverse clinical outcomes remain uncertain given the paucity of high-quality studies in this area. This meta-analysis was performed to evaluate the efficacy and adverse events of HFOV in adults with ARDS.MethodsWe searched PubMed, EMBASE and Cochrane Central Register of Controlled Trials through February 2014 to retrieve randomized controlled trials of HFOV in adult ARDS patients. Two independent reviewers extracted data on study methods, clinical and physiological outcomes and adverse events. The primary outcome was 30-day or hospital mortality. Risk of bias was evaluated with the Cochrane Collaboration’s tool. Mortality, oxygenation and adverse effects of HFOV were compared to those of conventional mechanical ventilation. A random-effects model was applied for meta-analysis.ResultsA total of five trials randomly assigning 1,580 patients met inclusion criteria. Pooled data showed that HFOV significantly improved oxygenation on day one of therapy (four studies; 24% higher; 95% confidence interval (CI) 11 to 40%; P <0.01). However, HFOV did not reduce mortality risk (five studies; risk ratio (RR) 1.04; 95% CI 0.83 to 1.31; P = 0.71) and two early terminated studies suggested a harmful effect of HFOV in ARDS (two studies; RR 1.33; 95% CI 1.09 to 1.62; P <0.01). Safety profiles showed that HFOV was associated with a trend toward increased risk of barotrauma (five studies; RR 1.19; 95% CI 0.83 to 1.72; P = 0.34) and unfavorable hemodynamics (five studies; RR 1.16; 95% CI 0.97 to 1.39; P = 0.12).ConclusionsHFOV improved oxygenation in adult patients with ARDS; however, it did not confer a survival benefit and might cause harm in the era of lung-protective ventilation strategy. The evidence suggests that HFOV should not be a routine practice in ARDS and further studies specifically selecting patients for this ventilator mode should be pursued.

Purpose Psoriasis is an inflammatory disease associated with cardiovascular disease. Methotrexate (MTX) is a first-line systemic anti-psoriatic agent that may also protect against cardiovascular disease. We examined the cardiovascular risks among patients with psoriasis who were receiving MTX or the comparator, retinoids. Patients and Methods We analysed data from the Taiwanese National Health Insurance database. The primary outcome was a composite of hospitalisation for ischaemic heart disease, ischaemic stroke and all-cause mortality (composite cardiovascular outcome). Propensity score-weighted analyses were used to evaluate patients who were followed from therapy initiation to the earliest instance of outcome occurrence, insurance disenrollment, death or study termination. Results We identified 13,777 patients who received MTX and 6020 patients who received retinoids from 2000 to 2012. Compared to retinoids, MTX was associated with lower crude incidences of cardiovascular outcomes, hospitalisation for ischaemic heart disease, ischaemic stroke and all-cause mortality. In intention-to-treat analyses, MTX was associated with lower risks of composite cardiovascular outcomes (adjusted hazard ratio [HR]: 0.84, 95% confidence interval [CI]: 0.76–0.94), ischaemic heart disease (HR: 0.87, 95% CI: 0.71–1.06), ischaemic stroke (HR: 1.06, 95% CI: 0.89–1.27) and all-cause mortality (HR: 0.75, 95% CI: 0.66–0.85). Similar results were found in as-treated analyses. Conclusion In this nationwide cohort of patients with psoriasis, compared to retinoids, MTX was associated with a modestly lower risk of cardiovascular events.
