Although viral infections are a major cause of exacerbations in patients with chronic airway diseases, their roles in triggering bronchiectasis exacerbations in adults remain unclear. Therefore, we prospectively investigated the incidence and clinical impacts of viral infection in adults with bronchiectasis exacerbations. ⋯ Prevalence of viral infections, detected by polymerase chain reaction assay, is higher in cases of bronchiectasis exacerbations than in steady-state bronchiectasis, suggesting that respiratory viruses play crucial roles in triggering bronchiectasis exacerbations. The potential mechanisms of virus-induced bronchiectasis exacerbations merit further investigations.

Recent findings suggest that patients with atrial fibrillation (AF), in addition being at thromboembolic risk, are at risk of myocardial infarction (MI). Our aim was to investigate predictors of MI and cardiovascular death in a cohort of patients with AF who were taking anticoagulants. ⋯ Patients with AF still experience a high rate of CVEs despite receiving anticoagulant treatment. MetS is a common clinical feature in patients with AF, which increases the risk of CVEs. A holistic approach is needed to reduce the cardiovascular risk in patients with AF.

Bronchoscopy in patients with space-occupying brain lesions is anecdotally felt to carry a high risk of neurologic complications. ⋯ On the basis of our findings, we recommend that procedures such as flexible or rigid bronchoscopy or EBUS-TBNA in patients with malignant space-occupying brain lesions should be considered reasonably safe as long as neurologic findings are stable.

A 52-year-old white man presented to a pulmonary clinic for evaluation of a 2.3 × 1.7 cm lung nodule. The patient had originally presented to his cardiologist for palpitations. The palpitations were described as a "fluttering" sensation, occurring daily, more often at rest, but not associated with syncope. ⋯ He had a 1 pack-year smoking history and stopped cigarettes 30 years ago but still smoked two to three cigars monthly. His family history was only significant for early coronary artery disease. He was an avid marathon runner who worked as an athletic equipment manager for a prominent sports team in Arizona.

Infectious disease epidemics in the past have given rise to psychologic and emotional responses among health-care workers (HCWs), stemming from fear of infection during patient care. Early experiences in the AIDS epidemic provide an example where fear of contagion resulted in differential treatment of patients infected with HIV. ⋯ Parallels exist between early experiences with AIDS and the present outbreak of Ebola virus disease in West Africa, particularly regarding discussions of medical futility in seriously ill patients. We provide a historical perspective on HCWs' risk of infection during the provision of CPR, discuss physicians' duty to treat in the face of perceived or actual HCW risk, and, finally, present the protocols implemented at the National Institutes of Health to reduce HCW risk while providing lifesaving and life-sustaining care.
