What The Study Did: The SARS-CoV-2 BNT162b2 (Pfizer-BioNTech) vaccine appeared to be safe and achieve satisfactory serologic status in patients with cancer. While there was a lag in antibody production compared with the rate in the noncancer control group, seroconversion occurred in most patients after the second dose.

What The Study Did:Researchers in this randomized clinical trial found that a large proportion of patients who canceled visits and procedures early in the COVID-19 pandemic didn’t reschedule once reopening occurred. A single message targeted directly to these patients didn’t affect the return to in-person visits within a month but it resulted in a small increase in re-engagement through telemedicine and rescheduling of future visits.

What The Study Did:This crossover trial found that perceived breathing resistance at peak exercise is uniquely and significantly elevated when exercise stress testing (EST) is performed while wearing a mask. Performing EST with a mask yielded lower peak exercise oxygen uptake and heart rates as compared with no mask. However, each experimental condition resulted in peak exercise values that generally remained within normal limits, and no EST required termination due to clinically indicated safety concerns. Thus, although it is possible that wearing a mask exerted a physical limitation on exercise capacity, the clinical relevance of such a possibility is not supported by these data.
