Impact of Face Masks on 6-Minute Walk Test in Healthy Volunteers.

Our objective was to establish the impact of wearing a face mask on the outcome of six-minute walk test in healthy volunteers. In a study of 20 healthy volunteers who each completed two 6MWTs, one with a mask and one without, there was no difference in distance walked. However, there was a significant difference in perception of dyspnea between the two groups.

Management of hemoptysis in patients with lung cancer.

Hemoptysis related to malignancy is common and accounts for nearly a quarter of all cases of hemoptysis in the US, and approximately 20% of patients with lung cancer will experience some degree of hemoptysis during their disease course. Both minor and massive hemoptysis come with diagnostic and treatment challenges and are associated with increased mortality. We will discuss the definition and epidemiology of hemoptysis related to malignancy, outline our approach to the initial evaluation and diagnostic workup, and extensively review the management of minor and massive hemoptysis.
