Lung Volume Reduction Coil Treatment vs Usual Care in Patients With Severe Emphysema: The REVOLENS Randomized Clinical Trial:
IMPORTANCE: Therapeutic options for severe emphysema are limited. Lung volume reduction using nitinol coils is a bronchoscopic intervention inducing regional parenchymal volume reduction and restoring lung recoil.
OBJECTIVE: To evaluate the efficacy, safety, cost, and cost-effectiveness of nitinol coils in treatment of severe emphysema.
DESIGN, SETTING, AND PARTICIPANTS: Multicenter 1:1 randomized superiority trial comparing coils with usual care at 10 university hospitals in France. Enrollment of patients with emphysema occurred from March to October 2013, with 12-month follow-up (last follow-up, December 2014).
INTERVENTIONS: Patients randomized to usual care (n = 50) received rehabilitation and bronchodilators with or without inhaled corticosteroids and oxygen; those randomized to bilateral coil treatment (n = 50) received usual care plus additional therapy in which approximately 10 coils per lobe were placed in 2 bilateral lobes in 2 procedures.
MAIN OUTCOMES AND MEASURES: The primary outcome was improvement of at least 54 m in the 6-minute walk test at 6 months (1-sided hypothesis test). Secondary outcomes included changes at 6 and 12 months in the 6-minute walk test, lung function, quality of life as assessed by St George's Respiratory Questionnaire (range, 0-100; 0 being the best and 100 being the worst quality of life; minimal clinically important difference, ≥4), morbidity, mortality, total cost, and cost-effectiveness.
RESULTS: Among 100 patients, 71 men and 29 women (mean age, 62 years) were included. At 6 months, improvement of at least 54 m was observed in 18 patients (36%) in the coil group and 9 patients (18%) in the usual care group, for a between-group difference of 18% (1-sided 95% CI, 4% to ∞; P = .03). Mean between-group differences at 6 and 12 months in the coil and usual care groups were +0.09 L (95% CI, 0.05 L to ∞) (P = .001) and +0.08 L (95% CI, 0.03 L to ∞) (P = .002) for forced expiratory volume in the first second, +21 m (95% CI, -4 m to ∞) (P = .06) and +21 m (95% CI, -5 m to ∞) (P = .12) for 6-minute walk distance, and -13.4 points (95% CI, -8 points to ∞) and -10.6 points (95% CI, -5.8 points to ∞) for St George's Respiratory Questionnaire (1-sided P < .001 for both). Within 12 months, 4 deaths occurred in the coil group and 3 in the usual care group. The mean total 1-year per-patient cost difference between groups was 47,879-782,598 per additional quality-adjusted life-year.
CONCLUSIONS AND RELEVANCE: In this preliminary study of patients with severe emphysema followed up for 6 months, bronchoscopic treatment with nitinol coils compared with usual care resulted in improved exercise capacity with high short-term costs. Further investigation is needed to assess durability of benefit and long-term cost implications.

Trichosporon mycotoxinivorans is a novel pathogen recently found in cystic fibrosis patients. We report the first case of a disseminated fatal infection with T. mycotoxinivorans associated with invasive Aspergillus fumigatus and Scedosporium apiospermum infection after lung and liver transplantation in a cystic fibrosis patient
A randomized controlled trial of presatovir for respiratory syncytial virus after lung transplant
Background: Respiratory syncytial virus (RSV) infection in lung transplant recipients is associated with high morbidity. This study evaluated the RSV fusion inhibitor presatovir in RSV-infected lung transplant recipients. Methods: In this international Phase 2b, randomized, double-blind, placebo-controlled trial (NCT02534350), adult lung transplant recipients with symptomatic confirmed RSV infection for ≤7 days received oral presatovir 200 mg on day 1 and 100 mg daily on days 2 to 14, or placebo (2:1), with follow-up through day 28. There were 2 coprimary endpoints: time-weighted average change in nasal RSV load from day 1 to 7, calculated from nasal swabs, in the full analysis set ([FAS]; all patients who received study drug and had quantifiable baseline nasal RSV load) and time-weighted average change in nasal RSV load from day 1 to 7 in the subset of patients with pretreatment symptom duration at the median or shorter of the FAS. Secondary endpoints were changes in respiratory infection symptoms assessed using the Influenza Patient-Reported Outcomes questionnaire and lung function measured by spirometry. Results: Sixty-one patients were randomized, 40 received presatovir, 20 placebo, and 54 were included in efficacy analyses. Presatovir did not significantly improve the primary endpoint in the FAS (treatment difference [95% CI], 0.10 [−0.43, 0.63] log10 copies/ml; p = 0.72) or the shorter symptom-duration subgroup (−0.12 [−0.94, 0.69] log10 copies/ml; p = 0.76). Secondary endpoints were not different between presatovir and placebo groups. Presatovir was generally well tolerated. Conclusions: Presatovir treatment did not significantly improve change in nasal RSV load, symptoms, or lung function in lung transplant recipients.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
Safety and Dose Study of Targeted Lung Denervation in Moderate/Severe COPD Patients
RATIONALE: Targeted lung denervation (TLD) is a novel bronchoscopic treatment for the disruption of parasympathetic innervation of the lungs. OBJECTIVES: To assess safety, feasibility, and dosing of TLD in patients with moderate to severe COPD using a novel device design. METHODS: Thirty patients with COPD (forced expiratory volume in 1 s 30-60%) were 1:1 randomized in a double-blinded fashion to receive TLD with either 29 or 32 W. Primary endpoint was the rate of TLD-associated adverse airway effects that required treatment through 3 months. Assessments of lung function, quality of life, dyspnea, and exercise capacity were performed at baseline and 1-year follow-up. An additional 16 patients were enrolled in an open-label confirmation phase study to confirm safety improvements after procedural enhancements following gastrointestinal adverse events during the randomized part of the trial. RESULTS: Procedural success, defined as device success without an in-hospital serious adverse event, was 96.7% (29/30). The rate of TLD-associated adverse airway effects requiring intervention was 3/15 in the 32 W versus 1/15 in the 29 W group, p = 0.6. Five patients early in the randomized phase experienced serious gastric events. The study was stopped and procedural changes made that reduced both gastrointestinal and airway events in the subsequent phase of the randomized trial and follow-up confirmation study. Improvements in lung function and quality of life were observed compared to baseline values for both doses but were not statistically different. CONCLUSIONS: The results demonstrate acceptable safety and feasibility of TLD in patients with COPD, with improvements in adverse event rates after procedural enhancements.status: publishe
Understanding the Time to Court Case Resolution: A Competing Risks Analysis Using Belgian Data
Court delays are a frequent concern, yet what explains court case duration remains incompletely understood. We study the time to court case resolution by drawing on a detailed case-level dataset of civil suits filed at a major Belgian court. We utilize the competing risks regression framework to address the typically neglected heterogeneity in the modes of court case resolution and examine the role of a wide range of both time-invariant and time-varying covariates. Controlling for judge fixed effects, we find substantial disparities in the effect of party and case characteristics on the time to settlement versus trial judgment. Exploiting the de facto random assignment of cases to serving judges within the court's chambers, we further find that judge characteristics matter for time to trial judgment, but not for time to settlement. Modeling heterogeneity in the modes of court case resolution is therefore central to understanding of court case durations
