Communicating with policy makers about climate change, health, and their intersection: a scoping review.

Ambitious policies are urgently needed to protect human health from the impacts of climate change. Civil society, including researchers and advocates, can help advance such policies by communicating with policy makers. In this scoping review, we examined what is known about effectively communicating with policy makers to encourage them to act on public health, climate change, or their nexus.

Altered coronary vascular control during cold stress in healthy older adults.

Cardiovascular-related mortality increases in the cold winter months, particularly in older adults. Previously, we reported that determinants of myocardial O(2) demand, such as the rate-pressure product, increase more in older adults compared with young adults during cold stress. The aim of the present study was to determine if aging influences the coronary hemodynamic response to cold stress in humans.
