Towards an understanding of the physical activity-BDNF-cognition triumvirate: a review of associations and dosage. Ageing Res Rev. 2020 Mar 11;:101044 Authors: Walsh EI, Smith L, Northey J, Rattray B, Cherbuin N Abstract Physical activity has received substantial research attention due to its beneficial impact on cognition in ageing, particularly via the action of brain-derived neurotrophic factor (BDNF). It is well established that physical activity can elevate circulating levels of BDNF, and that BDNF has neurotrophic, neuroprotective and cognitively beneficial properties. Yet, practical implementation of this knowledge is limited by a lack of clarity on context and dose-effect. Against a shifting backdrop of gradually diminishing physical and cognitive capacity in normal ageing, the type, intensity, and duration of physical activity required to elicit elevations in BDNF, and more importantly, the magnitude of BDNF elevation required for detectable neuroprotection remains poorly characterised. The purpose of this review is to provide an overview of the association between physical activity, BDNF, and cognition, with a focus on clarifying the magnitude of these effects in the context of normative ageing. We discuss the implications of the available evidence for the design of physical activity interventions intended to promote healthy cognitive ageing.

CONCLUSION: Use of VR facility tours as an alternative to in-person tours of affiliate training facilities during a residency interview day is a viable and innovative option that can save time and money and favorably impact the applicant's impression of the program. More research is necessary to assess whether VR tours can replace in-person tours at the main teaching site, however, while social distancing measures are in place, VR tours may become necessary for programs moving forward.

Authors: Roberts V, Malone K, Moore P, Russell-Webster T, Caulfield R Abstract Our personal views about the challenges of continuing to deliver peer teaching during a pandemic. We are a group of 4th year medical students who are part of a student society which has delivered structured, highly formulaic peer-led teaching sessions for the past three years. During the COVID-19 pandemic, the reduced access to our normal clinical teaching highlighted the importance of peer-led teaching sessions. We wanted to continue with our peer-taught sessions but knew we would have to devise a new format to make our teaching accessi...
