Lesion size is a significant factor predicting visualization of EBUS for PPL. The location of PPL on CT scans and position of the probe are significantly related to a higher diagnostic yield with EBUS-guided TBB.

Chronic obstructive pulmonary disease (COPD) is the leading cause of death worldwide, and poses a substantial economic and social burden. Telemonitoring has been proposed as a solution to this growing problem, but its impact on patient outcome is equivocal. This randomized controlled trial aimed to investigate effectiveness of telemonitoring in improving COPD patient outcome. In total, 106 subjects were randomly assigned to the telemonitoring (n = 53) or usual care (n = 53) group. During the two months following discharge, telemonitoring group patients had to report their symptoms daily using an electronic diary. The primary outcome measure was time to first re-admission for COPD exacerbation within six months of discharge. During the follow-up period, time to first re-admission for COPD exacerbation was significantly increased in the telemonitoring group than in the usual care group (p = 0.026). Telemonitoring was also associated with a reduced number of all-cause re-admissions (0.23 vs. 0.68/patient; p = 0.002) and emergency room visits (0.36 vs. 0.91/patient; p = 0.006). In conclusion, telemonitoring intervention was associated with improved outcomes among COPD patients admitted for exacerbation in a country characterized by a small territory and high accessibility to medical services. The findings are encouraging and add further support to implementation of telemonitoring as part of COPD care.

Objectives: Experience with extracorporeal membrane oxygenation for adult patients with refractory septic shock remains limited. We aimed to study the clinical features and outcomes of this patient group in an extracorporeal membrane oxygenation referral center in Taiwan.Methods: From January 2005 to December 2010, all adult patients in refractory septic shock and requiring venoarterial extracorporeal membrane oxygenation for circulatory support were included in the present study. The variables analyzed included patient demographics; comorbidities; smoking status; hemodynamic, ventilatory, and laboratory parameters just before extracorporeal membrane oxygenation support; clinical course; extracorporeal membrane oxygenation details; complications; microbiology results; and outcomes. The primary endpoint was survival to hospital discharge.Results: A total of 52 patients, 39 men and 13 women, were included during a 6-year period. Their median age and body mass index was 56.8 years and 24.1 kg/m 2 , respectively. Of the 52 patients, 39 (75%) had failure of at least 3 organ systems and 21 (40%) had developed cardiac arrest and received cardiopulmonary resuscitation at extracorporeal membrane oxygenation implantation. Of these 52 patients, 8 (15%) survived to hospital discharge. The nonsurvivors were significantly older than the survivors (59.3 vs 43.8 years; P ¼ .009), and all 20 patients (38%) aged 60 years or older died.

IntroductionNatural history of chronic obstructive pulmonary disease (COPD) is punctuated by exacerbations; however, little is known about prognosis of the first-ever COPD exacerbation and variables predicting its outcomes.Materials and MethodsA population-based cohort study among COPD patients with their first-ever exacerbations requiring hospitalizations was conducted. Main outcomes were in-hospital mortality and one-year mortality after discharge. Demographics, comorbidities, medications and in-hospital events were obtained to explore outcome predictors.ResultsThe cohort comprised 4204 hospitalized COPD patients, of whom 175 (4%) died during the hospitalization. In-hospital mortality was related to higher age (odds ratio [OR]: 1.05 per year; 95% confidence interval [CI]: 1.03–1.06) and Charlson comorbidity index score (OR: 1.08 per point; 95% CI: 1.01–1.15); angiotensin II receptor blockers (OR: 0.61; 95% CI: 0.38–0.98) and β blockers (OR: 0.63; 95% CI: 0.41–0.95) conferred a survival benefit. At one year after discharge, 22% (871/4029) of hospital survivors were dead. On multivariate Cox regression analysis, age and Charlson comorbidity index remained independent predictors of one-year mortality. Longer hospital stay (hazard ratio [HR] 1.01 per day; 95% CI: 1.01–1.01) and ICU admission (HR: 1.33; 95% CI: 1.03–1.73) during the hospitalization were associated with higher mortality risks. Prescription of β blockers (HR: 0.79; 95% CI: 0.67–0.93) and statins (HR: 0.66; 95% CI: 0.47–0.91) on hospital discharge were protective against one-year mortality.ConclusionsEven the first-ever severe COPD exacerbation signifies poor prognosis in COPD patients. Comorbidities play a crucial role in determining outcomes and should be carefully assessed. Angiotensin II receptor blockers, β blockers and statins may, in theory, have dual cardiopulmonary protective properties and probably alter prognosis of COPD patients. Nevertheless, the limitations inherent to a claims database study, such as the diagnostic accuracy of COPD and its exacerbation, should be born in mind.
