Gastroesophageal reflux (GER) is common in patients with idiopathic pulmonary fibrosis (IPF) and has been proposed as a potential contributor to disease progression and exacerbation. Whether treatment of GER improves health outcomes in patients with IPF is controversial. Our objective was to review the efficacy and safety of GER treatments in IPF.We performed a systematic review and meta-analysis,...
As seen in this CME online activity (available at http://journal.cme.chestnet.org/sv-sleep-disorder), central sleep apnea (CSA) is associated with increased mortality in patients with heart failure (HF), and it has been thought that treatment of CSA may improve underlying HF. Positive airway pressure therapy, specifically auto-servoventilation (ASV), can not only suppress abnormal breathing patterns...
Frailty is a strong indicator of vulnerability among older persons, but its association with ICU outcomes has not been evaluated prospectively (ie, with objective measurements obtained prior to ICU admission). Our objective was to prospectively evaluate the relationship between frailty and post-ICU disability, incident nursing home admission, and death.The parent cohort included 754 adults aged ≥...
Cardiovascular disease is a frequent comorbidity in patients with COPD. Many physicians, particularly pulmonologists, are reluctant to use β-adrenoceptor blocking agents (β-blockers) in patients with COPD, despite their proven effectiveness in preventing cardiovascular events.The large (5,162 patients) phase III TONADO 1 and 2 studies assessed lung function and patient-reported outcomes in patients...
Cavities occasionally are encountered on thoracic images. Their differential diagnosis is large and includes, among others, various infections, autoimmune conditions, and primary and metastatic malignancies. We offer an algorithmic approach to their evaluation by initially excluding mimics of cavities and then broadly classifying them according to the duration of clinical symptoms and radiographic...
Heparin-induced thrombocytopenia (HIT) is a prothrombotic drug reaction caused by platelet-activating antibodies that recognize platelet factor 4 (PF4)/heparin complexes. It is unknown whether platelet-activating antibodies are detectable at the onset of the HIT-related platelet count fall.Available blood samples from 18 patients obtained at onset of HIT were tested using the serotonin-release assay...
Lung cancer is a leading cause of death and hospitalization for patients with COPD. A detailed understanding of which clinical features of COPD increase risk is needed.We performed a nested case-control study of Genetic Epidemiology of COPD (COPDGene) Study subjects with and without lung cancer, age 45 to 80 years, who smoked at least 10-pack years to identify clinical and imaging features of smokers,...
