Long term (5 Year) safety of bronchial thermoplasty: Asthma Intervention Research (AIR) trial
<b>Background:</b>
Bronchial thermoplasty (BT) is a bronchoscopic procedure that improves asthma control by reducing excess airway smooth muscle. Treated patients have been followed out to 5 years to evaluate long-term safety of this procedure.
<br></br>
<br></br>
<b>Methods:</b>
Patients enrolled in the Asthma Intervention Research Trial were on inhaled corticosteroids ≥200 μg beclomethasone or equivalent + long-acting-beta2-agonists and demonstrated worsening of asthma on long-acting-β2-agonist withdrawal. Following initial evaluation at 1 year, subjects were invited to participate in a 4 year safety study. Adverse events (AEs) and spirometry data were used to assess long-term safety out to 5 years post-BT.

<br></br>
<b>Results:</b>
45 of 52 treated and 24 of 49 control group subjects participated in long-term follow-up of 5 years and 3 years respectively. The rate of respiratory adverse events (AEs/subject) was stable in years 2 to 5 following BT (1.2, 1.3, 1.2, and 1.1, respectively,). There was no increase in hospitalizations or emergency room visits for respiratory symptoms in Years 2, 3, 4, and 5 compared to Year 1. The FVC and FEV1 values showed no deterioration over the 5 year period in the BT group. Similar results were obtained for the Control group.

<b>Conclusions:</b>
The absence of clinical complications (based on AE reporting) and the maintenance of stable lung function (no deterioration of FVC and FEV1) over a 5-year period post-BT in this group of patients with moderate to severe asthma support the long-term safety of the procedure out to 5 years
The Incidence of Common Respiratory Viruses During the COVID-19 Pandemic: Results From the Louisville COVID-19 Epidemiology Study
Introduction: Social distancing has been utilized during the COVID-19 pandemic to reduce the spread of SARS-CoV-2, which is also expected to reduce the spread of common respiratory viruses.
Methods: This retrospective, descriptive study assessed the rate of positivity of common respiratory viruses from commercially available respiratory pathogen panel, across a five-hospital health-system, during four-week periods within March to April of 2019 and 2020.
Results: During the four-week period in 2019, the percent positivity of common respiratory viruses from week one to week four decreased from 6 to 32% among the four included viruses. In the comparator period in 2020, a decrease ranging from 74 to 100% was observed from week one to week four.
Conclusions: These data indicate that the social distancing efforts implemented in Louisville, Kentucky, may be associated with a decrease in incidence of common respiratory viruses. This decrease in positivity of common respiratory viruses may serve as a surrogate marker for the effect of social distancing on the transmission of SARS-CoV-2
