Limited data are available regarding the prognostic factors for patients with nontuberculous mycobacterial pulmonary disease (NTM-PD). We investigated the prognostic factors associated with long-term mortality in NTM-PD patients after adjusting for individual confounders, including aetiological organism and radiological form.A total of 1445 patients with treatment-naïve NTM-PD who were newly diagnosed between July 1997 and December 2013 were included. The aetiological organisms were as follows:Mycobacterium avium(n=655),M. intracellulare(n=487),M. abscessus(n=129) andM. massiliense(n=174). The factors associated with mortality in NTM-PD patients were analysed using a multivariable Cox model after adjusting for demographic, radiological and aetiological data.The overall 5-, 10- and 15-year cumulative mortality rates for the NTM-PD patients were 12.4%, 24.0% and 36.4%, respectively. On multivariable analysis, the following factors were significantly associated with mortality in NTM-PD patients: old age, male sex, low body mass index, chronic pulmonary aspergillosis, pulmonary or extrapulmonary malignancy, chronic heart or liver disease and erythrocyte sedimentation rate. The aetiological organism was also significantly associated with mortality:M. intracellularehad an adjusted hazard ratio (aHR) of 1.40, 95% CI 1.03–1.91;M. abscessushad an aHR of 2.19, 95% CI 1.36–3.51; andM. massiliensehad an aHR of 0.99, 95% CI 0.61–1.64, compared toM. avium. Mortality was also significantly associated with the radiological form of NTM-PD for the cavitary nodular bronchiectatic form (aHR 1.70, 95% CI 1.12–2.59) and the fibrocavitary form (aHR 2.12, 95% CI 1.57–3.08), compared to the non-cavitary nodular bronchiectatic form.Long-term mortality in patients with NTM-PD was significantly associated with the aetiological NTM organism, cavitary disease and certain demographic characteristics.

The clinical characteristics and optimal duration of corticosteroid treatment for acute eosinophilic pneumonia (AEP) have not been fully evaluated. This was a retrospective study of prospectively collected data from 137 patients with AEP, treated with standardised protocol, to clarify the clinical characteristics and compare the efficacies of 2 weeks versus 4 weeks of corticosteroid treatment for AEP. The majority of the patients altered their smoking habits within a median (interquartile range) of 17 (13-26) days prior to development of AEP. 80 (58%) patients presented with acute respiratory failure. A total of 127 (92%) patients were treated with corticosteroids: 4 weeks, n=42; 2 weeks, n=85. Major symptoms were resolved in 3 days and the severity of respiratory failure was inversely correlated with clinical outcomes. After adjusting for differences in baseline characteristics between the groups, the differences in adjusted mean (95% confidence interval) for resolution of dyspnoea and disappearance of all symptoms were 0.57 (-0.71-1.86) and -0.04 (-1.91-1.83) days, respectively. The difference in adjusted proportion of resolution of radiological abnormalities was 6.92% (-8.19-22.02). In conclusion, the duration of corticosteroid treatment could be shortened to 2 weeks, even in patients with respiratory failure.

Background: Coronavirus disease 2019 (COVID-19) is a disease caused by severe acute respiratory syndrome-coronavirus-2. Consensus suggestions can standardise care, thereby improving outcomes and facilitating future research.Methods: An International Task Force was composed and agreement regarding courses of action was measured using the Convergence of Opinion on Recommendations and Evidence (CORE) process. 70% agreement was necessary to make a consensus suggestion.Results: The Task Force made consensus suggestions to treat patients with acute COVID-19 pneumonia with remdesivir and dexamethasone but suggested against hydroxychloroquine except in the context of a clinical trial; these are revisions of prior suggestions resulting from the interim publication of several randomised trials. It also suggested that COVID-19 patients with a venous thromboembolic event be treated with therapeutic anticoagulant therapy for 3 months. The Task Force was unable to reach sufficient agreement to yield consensus suggestions for the post-hospital care of COVID-19 survivors. The Task Force fell one vote shy of suggesting routine screening for depression, anxiety and post-traumatic stress disorder.Conclusions: The Task Force addressed questions related to pharmacotherapy in patients with COVID-19 and the post-hospital care of survivors, yielding several consensus suggestions. Management options for which there is insufficient agreement to formulate a suggestion represent research priorities.

Definitive guidelines for anticoagulation management during veno-venous extracorporeal membrane oxygenation (VV ECMO) are lacking, while bleeding complications continue to pose major challenges. To describe anticoagulation modalities and bleeding events in adults receiving VV ECMO. International prospective observational study in 41 centers, from December 2018 to February 2021. Anticoagulation was recorded daily in terms of type, dosage, and monitoring strategy. Bleeding events were reported according to site, severity, and impact on mortality. The study cohort included 652 patients, and 8471 days on ECMO were analyzed. Unfractionated heparin (UFH) was the initial anticoagulant in 77% of patients, and the most used anticoagulant during the ECMO course (6221 days, 73%). Activated partial thromboplastin time (aPTT) was the most common test for monitoring coagulation (86% of days): the median value was 52 seconds (39-61), but dropped by 5.3 seconds after the first bleeding event (95% CI -7.4 to -3.2, p< 0.01). Bleeding occurred on 1202 days (16.5 %). Overall, 342 patients (52.5 %) experienced at least one bleeding event (one episode every 215 hours on ECMO), of which 10 (1.6%) were fatal. In a multiple penalized Cox proportional hazard model, higher aPTT was a potentially modifiable risk factor for the first episode of bleeding (for 20 seconds increase, hazard ratio 1.07). Anticoagulation during VV ECMO was a dynamic process, with frequent stopping in cases of bleeding, and restart according to the clinical picture. Future studies might explore lower aPTT targets to reduce the risk of bleeding.

Introduction: The aim of this study is to evaluate the effects of emergency department (ED) crowding on the implementation of tasks in the early resuscitation bundle during acute care of patients with severe sepsis and septic shock, as recommended by the Surviving Sepsis Campaign guidelines. Methods: We analyzed the sepsis registry from August 2008 to March 2012 for patients presenting to an ED of a tertiary urban hospital and meeting the criteria for severe sepsis or septic shock. The ED occupancy rate, which was defined as the total number of patients in the ED divided by the total number of ED beds, was used for measuring the degree of ED crowding. It was categorized into three groups (low; intermediate; high crowding). The primary endpoint was the overall compliance with the entire resuscitation bundle. Results: A total of 770 patients were enrolled. Of the eligible patients, 276 patients were assigned to the low crowding group, 250 patients to the intermediate crowding group, and 244 patients to the high crowding group (ED occupancy rate: ≤ 115; 116–149; ≥ 150%). There was significant difference in compliance rates among the three groups (31.9% in the low crowding group, 24.4% in the intermediate crowding group, and 16.4% in the high crowding group, P < 0.001). In a multivariate model, the high crowding group had a significant association with lower compliance (adjusted odds ratio (OR), 0.44; 95% confidence interval (CI), 0.26 to 0.76; P = 0.003). When the ED occupancy rate was included as a continuous variable in the model, it had also a negative correlation with the overall compliance (OR of 10% increase of the ED occupancy rate, 0.90; 95% CI, 0.84 to 0.96, P = 0.002). Conclusions: ED crowding was significantly associated with lower compliance with the entire resuscitation bundle and decreased likelihood of the timely implementation of the bundle elements.
