Patients who died from COVID-19 often had comorbidities, such as hypertension, diabetes, and chronic obstructive lung disease. Although angiotensin-converting enzyme 2 (ACE2) is crucial for SARS-CoV2 to bind and enter host cells, no study has systematically assessed the ACE2 expression in the lungs of patients with these diseases. Here, we analyzed over 700 lung transcriptome… Continue reading ACE2 Expression is Increased in the Lungs of Patients with Comorbidities Associated with Severe COVID-19

Association of Obstructive Sleep Apnea with Nighttime Blood Pressure in African Americans: the Jackson Heart Study
Obstructive sleep apnea (OSA), nocturnal hypertension, and non-dipping systolic blood pressure (BP) are each highly prevalent among African Americans. However, few data are available on the association between OSA and nighttime BP in this population.. ..Among 206 participants who completed ABPM and participated in the Jackson Heart Sleep Study, 50.5% had nocturnal hypertension and 26.2%… Continue reading Association of Obstructive Sleep Apnea with Nighttime Blood Pressure in African Americans: the Jackson Heart Study
Dose-Response Association of Low-Intensity and Nondaily Smoking With Mortality in the United States
An increasing proportion of US smokers smoke at low intensity and not every day. Some nondaily smokers have always had this pattern, whereas others previously smoked daily. The effect of reducing the level of smoking from daily to nondaily smoking and the dose response at low smoking levels are poorly understood.. ..Among 505 500 participants (aged… Continue reading Dose-Response Association of Low-Intensity and Nondaily Smoking With Mortality in the United States
Mid-Term Effects of Pulmonary #Rehabilitation on Cognitive Function in People with Severe Chronic Obstructive #Pulmonary Disease
Cognitive dysfunction is a common impairment associated with COPD. However, little is known about 1) its prevalence among those subjects referred for pulmonary rehabilitation (PR), 2) how it may affect the benefit of PR, 3) whether PR improves cognitive function and 4) whether cognitive dysfunction affects the usability of telehealth technology usually used to deliver… Continue reading Mid-Term Effects of Pulmonary #Rehabilitation on Cognitive Function in People with Severe Chronic Obstructive #Pulmonary Disease
Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma
..Asthma was identified by self-report. Habitual hours of sleep duration were categorized as short (≤5), normal (6-8), and long (≥9). Multivariate regression analyses were used to examine the associations between sleep duration and patient-reported outcomes and healthcare use. Results Of the 1389 adults with asthma, 26% reported short sleep duration, 66% reported normal sleep duration,… Continue reading Associations of #sleep duration with patient-reported outcomes and healthcare use in U.S. adults with #asthma
Sputum #microbiome profiles identify severe #asthma phenotypes of relative stability at 12-18 months
..Data were available for 100 severe asthma subjects (median age: 55 yrs, 42% males). Two microbiome-driven clusters were identified, characterized by differences in asthma onset, smoking status, residential locations, percentage of blood and/or sputum neutrophils and macrophages, lung spirometry, and concurrent asthma medications (all p-values <.05). Cluster 2 patients displayed a commensal-deficient bacterial profile which… Continue reading Sputum #microbiome profiles identify severe #asthma phenotypes of relative stability at 12-18 months
Early Transmission Dynamics in Wuhan, China, of Novel #Coronavirus–Infected Pneumonia
The initial cases of novel coronavirus (2019-nCoV)–infected pneumonia (NCIP) occurred in Wuhan, Hubei Province, China, in December 2019 and January 2020. We analyzed data on the first 425 confirmed cases in Wuhan to determine the epidemiologic characteristics of NCIP.. ..Among the first 425 patients with confirmed NCIP, the median age was 59 years and 56%… Continue reading Early Transmission Dynamics in Wuhan, China, of Novel #Coronavirus–Infected Pneumonia
Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
There has been limited evidence for the association between chronic obstructive pulmonary disease (COPD) and the incidence of lung cancer among never smokers. We aimed to estimate the risk of lung cancer incidence in never smokers with COPD, and to compare it with the risk associated with smoking. This cohort study involved 338 548 subjects, 40… Continue reading Chronic #obstructive pulmonary disease and lung cancer incidence in never smokers: a cohort study
Antibiotic Use and Outcomes in Children in the Emergency Department With Suspected #Pneumonia
Antibiotic therapy is often prescribed for suspected community-acquired pneumonia (CAP) in children despite a lack of knowledge of causative pathogen. Our objective in this study was to investigate the association between antibiotic prescription and treatment failure in children with suspected CAP who are discharged from the hospital emergency department (ED).. ..Of 337 eligible children, 294… Continue reading Antibiotic Use and Outcomes in Children in the Emergency Department With Suspected #Pneumonia
