Breath analysis is a promising noninvasive technique that offers a wide range of opportunities to facilitate early diagnosis of lung cancer (LC). Method Exhaled breath samples of 352 subjects including 160 with lung cancer (LC), 70 with benign pulmonary nodule (BPN) and 122 healthy controls (HC) were analyzed through thermal desorption coupled with gas chromatography-mass… Continue reading Calculated indices of volatile organic compounds (VOCs) in exhalation for #lung #cancer screening and early detection

#Antibiotic exposure during pregnancy and childhood #asthma: a national birth cohort study investigating timing of exposure and mode of delivery
...A total of 5522 (17%) children were born to mothers exposed to antibiotics during pregnancy. In adjusted analyses, children born to exposed mothers had higher odds of asthma (OR 1.14, 95% CI 1.05 to 1.24). There was no association with antibiotic exposure in the first trimester (OR 1.02, 95% CI 0.83 to 1.26), but higher… Continue reading #Antibiotic exposure during pregnancy and childhood #asthma: a national birth cohort study investigating timing of exposure and mode of delivery
#Cancer Statistics, 2021
Each year, the American Cancer Society estimates the numbers of new cancer cases and deaths in the United States and compiles the most recent data on population‐based cancer occurrence. Incidence data (through 2017) were collected by the Surveillance, Epidemiology, and End Results Program; the National Program of Cancer Registries; and the North American Association of… Continue reading #Cancer Statistics, 2021
Distinct developmental pathways from blood #monocytes generate human #lung macrophage diversity
The study of human macrophages and their ontogeny is an important unresolved issue. Here, we use a humanized mouse model expressing human cytokines to dissect the development of lung macrophages from human hematopoiesis in vivo. Human CD34+ hematopoietic stem and progenitor cells (HSPCs) generated three macrophage populations, occupying separate anatomical niches in the lung. Intravascular… Continue reading Distinct developmental pathways from blood #monocytes generate human #lung macrophage diversity
When to Use Initial Triple Therapy in #COPD: Adding a LAMA to ICS/LABA by Clinically Important Deterioration Assessment
Triple therapy versus dual therapy for chronic pulmonary obstructive disease (COPD) can reduce symptoms, limit the risk of acute exacerbations (AEs) as well as improve lung function. Currently, studies that feature clinically important deterioration (CID) as a composite endpoint to assess the need for treatment intensification for patients maintained on dual therapy remained to be… Continue reading When to Use Initial Triple Therapy in #COPD: Adding a LAMA to ICS/LABA by Clinically Important Deterioration Assessment
Poor outcome of #SARS-CoV-2 infection in patients with severe #asthma on biologic therapy
It is unclear whether asthma and asthma medications increase or decrease the risk of severe COVID-19, and this is particularly true for patients with severe asthma receiving biologics. Objectives The aim of this study was to assess incidence and disease course of COVID-19 in patients with severe asthma on biologic therapy (omalizumab, mepolizumab, reslizumab, benralizumab,… Continue reading Poor outcome of #SARS-CoV-2 infection in patients with severe #asthma on biologic therapy
Effectiveness of #Prone Positioning in Nonintubated Intensive Care Unit Patients With Moderate to Severe Acute Respiratory Distress Syndrome by #Coronavirus Disease 2019
In the treatment for severe acute respiratory distress syndrome (ARDS) from coronavirus disease 2019 (COVID-19), the World Health Organization (WHO) recommends prone positioning (PP) during mechanical ventilation for periods of 12–16 h/d to potentially improve oxygenation and survival. In this prospective observational study, we evaluated the ability of long PP sessions to improve oxygenation in… Continue reading Effectiveness of #Prone Positioning in Nonintubated Intensive Care Unit Patients With Moderate to Severe Acute Respiratory Distress Syndrome by #Coronavirus Disease 2019
Managing #Asthma in Adolescents and Adults 2020 Asthma Guideline Update From the National Asthma Education and Prevention Program
Asthma is a major public health problem worldwide and is associated with excess morbidity, mortality, and economic costs associated with lost productivity. The National Asthma Education and Prevention Program has released the 2020 Asthma Guideline Update with updated evidence-based recommendations for treatment of patients with asthma.. ..From 20 572 identified references, 475 were included in the… Continue reading Managing #Asthma in Adolescents and Adults 2020 Asthma Guideline Update From the National Asthma Education and Prevention Program
Interrelationships between small airways dysfunction, neutrophilic #inflammation and exacerbation frequency in #COPD
Small airways disease (SAD) is a key component of COPD and is a main contributing factor to lung function decline.. ..Thirty nine COPD subjects defined as either frequent exacerbators ( ≥ 2 exacerbations per year, n = 17) and infrequent exacerbators (≤1 exacerbation per year, n = 22) underwent Forced Oscillation Technique (R5-R19, AX), multiple… Continue reading Interrelationships between small airways dysfunction, neutrophilic #inflammation and exacerbation frequency in #COPD
