TOPIC IMPORTANCE: Lung cancer is the leading cause of cancer related deaths. Early detection and diagnosis are critical as survival decreases with advanced stages. Approximately 1.6 million nodules are incidentally detected every year on chest computed tomography in the United States. This number of nodules identified is likely much larger after accounting for screening detected nodules. Most of these nodules, whether incidentally or screening-detected, are benign. Despite this, many patients undergo unnecessary invasive procedures to rule out cancer as our current stratification approaches are suboptimal, particularly for intermediate probability nodules...

BACKGROUND: Introduction of novel therapies for cystic fibrosis (CF), raises the question whether traditional treatments can be withdrawn. Nebulized hypertonic saline (HS) could potentially be discontinued in patients receiving Dornase alfa (DA). RESEARCH QUESTION: In the pre-modulator era, did people with CF who were F508del homozygous (CFF508del ) and received DA and HS have better preserved lung function than those treated with DA only? STUDY DESIGN: Retrospective analysis of CF Foundation Patient Registry data (2006-2014)...

BACKGROUND: Patients with COPD are at high risk of developing lung cancer, but no validated predictive biomarkers have been reported to identify these patients. Molecular profiling of exhaled breath by electronic nose (eNose) technology may qualify for early detection of lung cancer in COPD patients. RESEARCH QUESTION: Can eNose technology be used for prospective detection of early lung cancer in COPD patients? STUDY DESIGN AND METHODS: BreathCloud is a real-world multicenter, prospective follow-up study using diagnostic and monitoring visits in day-to-day clinical care of patients with a standardized diagnosis of asthma, COPD or lung cancer...

REVIEW
Amit Chopra, Peter Doelken, Kurt Hu, John T Huggins, Marc A Judson
TOPIC IMPORTANCE: Pressure-dependent pneumothorax is a common clinical event, often occurring after pleural drainage in patients with visceral pleural restriction, partial lung resection or lobar atelectasis from bronchoscopic lung volume reduction or an endobronchial obstruction. This type of pneumothorax and air leak is clinically inconsequential. Failure to appreciate the benign nature of such air leaks may result in unnecessary pleural procedures or prolonged hospital stays. REVIEW FINDINGS: This review suggests that identification of a pressure-dependent pneumothorax is clinically important, as the air leak that results is not related to a lung injury that requires repair but rather to a physiologic consequence of a pressure gradient...

BACKGROUND: Delayed mortality in sepsis is often linked to a lack of resolution in the inflammatory cascade termed persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Limited research exists on PICS in pediatric patients with sepsis. RESEARCH QUESTION: What is the prevalence of pediatric persistent inflammation, immunosuppression, and catabolism syndrome (pPICS) in patients who died from sepsis-related mortalities and what associated pathogen profiles and co-morbidities did they have compared to those patients without? STUDY DESIGN AND METHODS: A retrospective study of a single institution using a de-identified database from 1997 to 2020 for all patients 21 years of age or less who died with culture-positive sepsis from a known source and who had laboratory data available were evaluated for the presence of pPICS...

BACKGROUND: The relationship between obstructive sleep apnea (OSA) and cancer is unclear. RESEARCH QUESTION: What is the association between OSA and cancer prevalence and incidence in a large Western Australian (WA) sleep clinic cohort (N=20,289)? STUDY DESIGN AND METHODS: OSA severity was defined by apnea-hypopnea index (AHI) and nocturnal hypoxemia (duration and percentage at SpO2 <90%) measured by in-laboratory polysomnography. Measures of potential confounding included age, sex, body-mass-index (BMI), smoking, socioeconomic status (SES) and blood pressure...

BACKGROUND: Whether intubation should be initiated early in the clinical course of critically ill patients remains a matter of debate. Results from prior observational studies are difficult to interpret because of avoidable flaws including immortal time bias, inappropriate eligibility criteria, and unrealistic treatment strategies. RESEARCH QUESTION: Do treatment strategies that intubate patients early in their critical care admission improve 30-day survival compared to strategies that delay intubation? STUDY DESIGN AND METHODS: We estimated the effect of strategies that require early intubation of critically ill patients compared to those that delay intubation...

TOPIC IMPORTANCE: Even though patients suffering from pulmonary arterial hypertension have multiple therapeutic options, the disease can be refractory despite appropriate management. In patients with end-stage pulmonary arterial hypertension, lung transplantation has the potential to both extend survival and improve health-related quality of life. Pulmonary arterial hypertension is the only major diagnostic indication for transplantation that is not a parenchymal pulmonary process, thus the care of these patients is unique...

Heritable pulmonary arterial hypertension (PAH) is an uncommon cause of PAH and is associated most frequently with pathogenic variants of BMPR2. Prior studies have described abnormalities in pulmonary arterial, venous, and bronchial artery vessels associated with these pathogenic variants. In this series, we describe two patients who demonstrated pulmonary arteriovenous malformations (AVMs) and incidentally were identified by a next generation sequencing gene panel to carry variants of BMPR2 in the absence of PAH...
