Gastroesophageal reflux disease (GERD) is a common comorbidity of nontuberculous mycobacteria (NTM) pulmonary disease (PD). Although GERD is associated with more symptoms and severe disease in patients with NTM PD, whether GERD is associated with an increased risk of NTM PD developing is unknown. ⋯ GERD is associated with an increased incidence of NTM PD. Older age and bronchiectasis are risk factors for NTM PD in patients with GERD. NTM PD in patients with GERD is associated with increased health-care use.

Clinical Trial
Factors Associated with Smoking Cessation Attempts in Lung Cancer Screening: A Secondary Analysis of the National Lung Screening Trial.
Lung cancer remains the leading cause of cancer-related mortality in the United States. The National Lung Screening Trial (NLST) demonstrated a 20% reduction in lung cancer mortality resulting from lung cancer screening (LCS) with an additive reduction from smoking abstinence. However, successful smoking cessation within LCS is variable. ⋯ In this analysis, only one-quarter of patients who underwent LCS and who smoked were treated with pharmacologic therapy, which is associated with increased likelihood of attempting to quit. Certain characteristics are associated with difficulty with attempting to quit smoking. Those with high nicotine dependence benefitted most from dual pharmacologic therapy.

Critically ill patients sometimes remember periods of neuromuscular blockade. ⋯ Among patients intubated emergently using a neuromuscular blocking agent, 7.4% of patients recalled awareness without being able to move, which was more likely when patients had a normal level of consciousness prior to intubation.

Observational Study
Diaphragmatic thickness and excursion in infants born preterm with bronchopulmonary dysplasia compared to term or near term infants: a prospective observational study.
Diaphragmatic atrophy associated with mechanical ventilation is reported in pediatric and adult patients, but a similar association has not been described in preterm infants with bronchopulmonary dysplasia (BPD). ⋯ In infants with BPD, DTexp was significantly lower, whereas DTF and DE were significantly higher, compared with healthy, age-matched control participants. Future studies are required and should focus on describing the evolution of diaphragmatic dimensions in preterm infants with and without BPD.

A 53-year-old woman with a history of pulmonary embolism treated with rivaroxaban came to the ED after 4 days of acutely worsening dyspnea and chest pressure. On arrival, her temperature was 36.7 °C; heart rate, 71 beats/min; BP, 98/59 mm Hg; respiratory rate, 22 breaths/min; and Spo2 95% on room air. Her WBC count was elevated at 15,770/μL; hemoglobin, 13.3 g/dL; platelets, 280,000/μL; INR (international normalized ratio), elevated at 1.66; and partial thromboplastin time, elevated at 18.8 s. Serum chemistry results were unremarkable, and pro-brain natriuretic peptide was slightly elevated at 530 pg/mL (normal, < 300 pg/mL).
