ARDS and High Blood Endocan Profile During COVID‑19
With great interest, we read the recently published paper by Pascreau et al. concluding that a high blood endocan profile during COVID‑19 distinguishes moderate from severe acute respiratory distress syndrome (ARDS). In... read more
Oxidized DNA Precursors Cleanup by NUDT1 Contributes to Vascular Remodeling in Pulmonary Arterial Hypertension
By overexpressing NUDT1, PAH-PASMCs hijack persistent oxidative stress in preventing incorporation of oxidized nucleotides into DNA, thus allowing the cell to escape apoptosis and proliferate. Given that NUDT1 inhibitors... read more
Mitochondrial Damage-Associated Molecular Patterns Exacerbate Lung Fluid Imbalance Via the Formyl Peptide Receptor-1 Signaling Pathway in Acute Lung Injury
Mitochondrial damage–associated molecular patterns exacerbate lung fluid imbalance in the experimental acute lung injury model through formyl peptide receptor-1 signaling, the inhibition of which may prevent exacerbation... read more
Doppler Echocardiographic Indices in Critically Ill Patients Under Mechanical Ventilation
Doppler Echocardiographic Indices Are Specific But Not Sensitive to Predict Pulmonary Artery Occlusion Pressure in Critically Ill Patients Under Mechanical Ventilation. The objective of this study was to prospectively... read more
The voice of people living with COPD: what I learned from doing qualitative research
As a general respiratory physician, schooled in the clinical world of evidence-based medicine (EBM), I shared a common view that qualitative research was, well, flaky. Where was the science? The statistical significance?... read more
Epidemiology of Invasive Pulmonary Aspergillosis Among COVID-19 Intubated Patients
We found a high incidence of CAPA among critically ill COVID-19 patients and that its occurrence seems to change the natural history of disease. A total of 108 patients were enrolled. Prospective, multicentre study... read more
Inhaled Pulmonary Vasodilators
Confusion between inhaled versus intravenous routes for pulmonary vasodilators. For optimal clinical benefit (especially regarding oxygenation), these agents must be given via an inhaled route. The misconception that inhaled... read more
Rapid Advancement in Enteral Nutrition Does Not Affect Systemic Inflammation and Insulin Homeostasis Following Pediatric Cardiopulmonary Bypass Surgery
A FF strategy was not associated with changes to early enteral nutrition delivery. Inflammation, insulin resistance, and morbidity were similar, but FF may modify the relationship between inflammation and adverse event. Multicenter... read more
COVID-19: A Hypothesis Regarding the Ventilation-Perfusion Mismatch
We believe that a severe V/Q mismatch underlies the pathophysiology of moderate to severe COVID-19 cases, in which downregulation of ACE2 secondary to viral endocytosis plays a key role. There is low V/Q ratio in areas of... read more
COVID-19: Thrombosis and Anticoagulation
Early reports have shown that COVID-19 is most likely causing a hypercoagulable state, however the prevalence of acute VTE and exactly how to treat it is an evolving area. Limited data suggest pulmonary microvascular thrombosis... read more
Leading EHR System Adopts Bundle to Prevent ICU Delirium
Seminal studies at Vanderbilt University Medical Center over the past two decades by pulmonary and critical care specialist Wes Ely, M.D. and colleagues have spurred ICU delirium research, and the resulting body of evidence... read more
Artificial Intelligence or Merely a Symptom of a Broken Healthcare System?
We are constantly hunting for newer and better sources of information. This leads to a perpetual generation of newer lab tests, different hemodynamic gizmos, and fresh decision tools. Some of these pan out. Most don't. Why... read more
Harrison’s Pulmonary and Critical Care Medicine
Featuring a superb compilation of chapters related to pulmonary and critical care topics, this concise, full-color clinical companion delivers the latest knowledge in the field backed by the scientific rigor and authority... read more
Recommendations for a Standardized Pulmonary Function Report
The American Thoracic Society committee on Proficiency Standards for Pulmonary Function Laboratories has recognized the need for a standardized reporting format for pulmonary function tests. Although prior documents have... read more
Building Critical Care Community Through Twitter Chat
Twitter chats can be a powerful tool for the widespread engagement of a medical audience. Social media sites such as Twitter can significantly enhance education and advocacy efforts. In 2013, the American College of Chest... read more
COPD Patients Who Live Alone are Less Active
Patients with chronic obstructive pulmonary disease (COPD) who live with a spouse, partner, or other caregiver are more active than patients who live alone, and are also more likely to participate in pulmonary rehabilitation... read more
PaCO2 Equation
I've previously written about the alveolar gas equation and oxygen delivery equation, both of which deal with the physiologic process of oxygenation. Now I want to discuss the important relationship between alveolar... read more
