Navigating the risks of flying during COVID-19: a review for safe air travel.

Rationale For Review: With air travel restarting, there has been much discourse about the safety of flying during the pandemic. In travel medicine, risk assessment includes estimating baseline risk to the traveller, recognizing factors that may modify that risk, considering the role of interventions to decrease that risk and accounting for a traveller's perception and tolerance of risk. The goals of this review are to identify the in-flight transmission risks of commercial air travel, provide recommendations about the risks of flying during the pandemic and propose strategies to mitigate the spread of COVID-19.

Longer term assessment of photodynamic therapy for intimal hyperplasia: a pilot study.

Purpose: To determine the potential long term (three or six months) effectiveness of photodynamic therapy (PDT) in reducing intimal hyperplasia in swine.

Methods: Intimal hyperplasia in the abdominal aortae of swine was created by a combination of fat-supplemented diet and balloon catheter injury prior to PDT. Swine were randomly allocated into one of three groups which received either: (i) both drug and light (PDT), (ii) drug only, or (iii) light only.
