BACKGROUND: Neutrophil Extracellular Traps (NETs) are increasingly implicated in acute and chronic conditions involving multiple organ systems. RESEARCH QUESTION: Are NETs concentrations higher in parapneumonic effusions compared to effusions of other etiologies and does this reflect the inflammatory nature of these effusions? STUDY DESIGN AND METHODS: Patients (N=101) presenting to hospital with undifferentiated pleural effusion for investigation had pleural fluid classified based on cytology, biochemical, microbiological characteristics, and clinical judgement...

BACKGROUND: Previous research shows that a lung ultrasound score (LUS) can anticipate CPAP failure in neonatal respiratory distress syndrome. RESEARCH QUESTION: Can LUS also predict the need for surfactant replacement? STUDY DESIGN AND METHODS: Multicenter, pragmatic study on preterm neonates who underwent lung ultrasound at birth and those given surfactant by masked physicians were also scanned within 24 hours from administration. Clinical data and respiratory support variables were recorded...

BACKGROUND: Limited existing data suggest the novel coronavirus disease 2019 (Covid-19) may increase risk for venous thromboembolism (VTE) but information from large, ethnically diverse populations with appropriate controls are lacking. RESEARCH QUESTION: Does the rate of VTE among adults hospitalized with Covid-19 differ from matched hospitalized controls without Covid-19? STUDY DESIGN AND METHODS: We conducted a retrospective study among hospitalized adults with laboratory-confirmed Covid-19 and hospitalized adults without evidence of Covid-19 matched on age, gender, race/ethnicity, acute illness severity, and month of hospitalization between February-August 2020 from two integrated healthcare delivery systems with 36 hospitals...

People with Cystic fibrosis (pwCF) have experienced increased survival and wellbeing in recent decades, such that more than half of those living with CF are adults. Consequently, sexual and reproductive health is increasingly important for pwCF as many are considering parenthood. Most men and some women with CF (wwCF) will have reduced fertility, which in both sexes is multifactorial. However, unplanned pregnancies in women are not rare, and contraception and its interaction with CF complications need to be addressed by the CF team...

Acute pulmonary embolism (PE) is associated with significant morbidity and mortality. The management paradigm for acute PE has evolved in recent years with wider availability of advanced treatment modalities ranging from catheter-directed reperfusion therapies to mechanical circulatory support. This evolution has coincided with the development and implementation of institutional pulmonary embolism response teams (PERT) nationwide and internationally. Because most institutions are not equipped or staffed for advanced PE care, patients often require transfer to centers with more comprehensive resources including PERT expertise...

REVIEW
Yasin A Khan, Eddy Fan, Niall D Ferguson
Acute respiratory distress syndrome (ARDS) is a clinically heterogenous syndrome, rather than a distinct disease. This heterogeneity at least partially explains the difficulty in studying treatments for these patients and contributes to the numerous trials of therapies for the syndrome that have not shown benefit. Recent studies have identified different subphenotypes within the heterogenous patient population. These different subphenotypes likely have variable clinical responses to specific therapies, a concept known as heterogeneity of treatment effect (HTE)...

BACKGROUND: Pulmonary hypertension is a heterogeneous disease and a significant portion of patients at risk for it have available computed tomography (CT) imaging. Advanced automated processing techniques could be leveraged to for early detection, screening and development of quantitative phenotypes. Pruning and vascular tortuosity have been previously described in pulmonary arterial hypertension (PAH) but the extent of these phenomena in arterial versus venous pulmonary vasculature and in exercise pulmonary hypertension (ePH) have not been described...

The point-of-care ultrasound deep venous thrombosis exam (POCUS DVT exam) can facilitate rapid bedside diagnosis and treatment of lower extremity DVT. Awaiting radiology-performed Doppler ultrasonography and interpretation by radiologists can lead to delays in lifesaving anticoagulation, and the POCUS DVT exam can provide timely diagnostic information in the patient with lower extremity symptoms. This article outlines accepted techniques for the POCUS DVT exam, discusses the historical context from which the current recommendations have evolved, and provides illustrations alongside ultrasound images of relevant venous anatomy to orient the clinician...

CASE EXAMPLE: A 56-year-old gentleman has difficult to control asthma and a history of four exacerbations in the prior 12 months despite high-dose inhaled corticosteroids (ICS) and additional controller therapies. Is he suitable for more advanced therapeutic options? SCOPE OF REVIEW: We herein review the clinical assessment of a patient with suspected severe asthma, discuss factors contributing to poor asthma control and how biomarkers assist in disease investigation and stratification...

BACKGROUND: The optimal diagnostic and staging strategy for patients with suspected lung cancer is not known. RESEARCH QUESTION: What diagnostic and staging strategies are most cost-effective for lung cancer? STUDY DESIGN AND METHODS: A decision model was developed using a hypothetical patient with a high probability of lung cancer. Sixteen unique permutations of bronchoscopy with fluoroscopy, radial endobronchial ultrasound (rEBUS), electromagnetic navigation, convex EBUS (cEBUS) with or without rapid-onsite evaluation (ROSE), computed tomography guided biopsy (CTBx) and surgery were evaluated...

BACKGROUND: Low-dose chest CT screening for lung cancer has become a standard of care in the United States, in large part due to the results of the National Lung Screening Trial. Additional evidence supporting the net benefit of low-dose chest CT screening for lung cancer, as well as increased experience in minimizing the potential harms, has accumulated since the prior iteration of these guidelines. Here, we update the evidence base for the benefit, harms, and implementation of low-dose chest CT screening...

BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is associated with a poor prognosis with variable clinical course. Early identification of patients at high risk for disease progression and death would lead to early therapeutic intervention and thereby improvement of outcomes. Cold-inducible RNA-binding protein (CIRBP) is produced in response to cellular stresses, which is implicated in multiple biological processes, including cell survival and proliferation. RESEARCH QUESTION: Is CIRBP a useful biomarker for predicting the outcomes of patients with IPF? STUDY DESIGN AND METHODS: This study included 95 and 93 patients with IPF from two independent hospitals (derivation and validation cohorts, respectively)...

BACKGROUND: Lung cancer is the leading cause of cancer death in women in the United States. Prospective randomized lung screening trials suggest a greater lung cancer mortality benefit from screening women compared to men. RESEARCH QUESTION: Do the United States Preventative Services Task Force (USPSTF) lung screening guidelines that are based solely on age and smoking history contribute to gender disparities in eligibility, and if so, does the use of the PLCOm2012 risk prediction model that is based on 11 predictors of lung cancer reduce gender disparities? STUDY DESIGN AND METHODS: This retrospective analysis of 883 lung cancer cases in the Chicago Race Eligibility for Screening Cohort (CREST) determined the sensitivity of USPSTF versus PLCOm2012 eligibility criteria, stratified by gender...
