Observational Study
Contribution of pulmonary diseases to COVID-19 mortality in a diverse urban community of New York.
We examined the relative contribution of pulmonary diseases (chronic obstructive pulmonary disease, asthma and sleep apnea) to mortality risks associated with Coronavirus Disease (COVID-19) independent of other medical conditions, health risks, and sociodemographic factors. Data were derived from a large US-based case series of patients with COVID-19, captured from a quaternary academic health network covering New York City and Long Island. From March 2 to May 24, 2020, 11,512 patients who were hospitalized were tested for COVID-19, with 4,446 (38.62%) receiving a positive diagnosis for COVID-19. ⋯ Higher mortality risks were also associated with a history of COPD (HR = 1.27; 95% CI: 1.02-1.58), obesity (HR = 1.19; 95% CI: 1.04-1.37), and peripheral artery disease (HR = 1.33; 95% CI: 1.05-1.69). Findings indicate patients with COPD had the highest odds of COVID-19 mortality compared with patients with pre-existing metabolic conditions, such as obesity, diabetes and hypertension. Sociodemographic factors including increased age, male sex, low household income, ethnic minority status were also independently associated with greater mortality risks.

Knowledge on the sequelae of Coronavirus Disease 2019 (COVID-19) remains limited due to the relatively recent onset of this pathology. However, the literature on other types of coronavirus infections prior to COVID-19 reports that patients may experience persistent symptoms after discharge. To determine the prevalence of respiratory symptoms in survivors of hospital admission after COVID-19 infection. ⋯ Of the 1,154 reports returned by the initial search nine articles were found, in which 1,816 patients were included in the data synthesis. In the pooled analysis, we found a prevalence of 0.52 (CI 0.38-0.66, p < 0.01, I 2 = 97%), 0.37 (CI 0.28-0.48, p < 0.01, I 2 = 93%), 0.16 (CI 0.10-0.23, p < 0.01, I 2 = 90%) and 0.14 (CI 0.06-0.24, p < 0.01, I 2 = 96%) for fatigue, dyspnoea, chest pain, and cough, respectively. Fatigue, dyspnoea, chest pain, and cough were the most prevalent respiratory symptoms found in 52%, 37%, 16% and 14% of patients between 3 weeks and 3 months, after discharge in survivors of hospital admission by COVID-19, respectively.

The COVID pandemic has had a high psychological impact on healthy populations. Increased levels of perceived stress, depression, and insomnia are expected, especially in people with pre-existing medical conditions, such as asthma and chronic obstructive pulmonary disease (COPD), who seem to be particularly vulnerable. However, the difference in psychological distress frequency between asthma and COPD patients is unknown. ⋯ Asthma and COPD patients present similar frequencies of depression risk, COVID-19 perceived stress, post-traumatic stress risk, and insomnia risk during the Colombian lockdown. It is essential to evaluate and manage psychological distress among asthma and COPD patients. It can reduce the risk of exacerbation and improve the quality of life.

Comparative Study
Differences in clinical features of acute exacerbation between connective tissue disease-associated interstitial pneumonia and idiopathic pulmonary fibrosis.
Acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) is a devastating condition that frequently occurs in the advanced stage of IPF. However, the clinical features in AE of connective tissue disease-associated interstitial pneumonia (AE-CTD-IP) have not been well-established. The aim of this study was to clarify the clinical features of AE-CTD-IP and to compare them with those of AE-IPF. ⋯ At AE, AE-CTD-IP patients showed higher white blood cell counts (12.0 vs. 9.9 × 103/μL; p = 0.023), higher CRP (10.2 vs. 6.7 mg/dL; p = 0.027), and longer period from admission to the beginning of AE treatment (4 vs. 1 days; p = 0.003) than AE-IPF patients. In addition, patients with AE-CTD-IP had poor prognosis as in those with AE-IPF (log-rank; p = 0.171). In conclusion, AE-CTD-IP occurred even in the early stage of IP and had more inflammatory status than in AE-IPF.

Global Initiative for Chronic Obstructive Lung Disease guidelines support the prescription of fixed combination inhaled corticosteroids (ICS) and long-acting β-agonists in symptomatic COPD patients with frequent or severe exacerbations, with the aim of preventing them. ICS are frequently also prescribed to COPD patients with mild or moderate airflow limitation, outside guidelines, with the risk of unwanted effects. No investigation to date has addressed the views of these milder COPD patients on ICS withdrawal. ⋯ Attitudes in this study to discontinuing ICS use varied. Knowledge of the drug itself, the indications for its prescription in COPD and potential for side effects, was scant. The proposed withdrawal of ICS is likely to be challenging and requires detailed conversations between patients and respiratory healthcare professionals.
