Lower Mortality From Coronary Heart Disease and Stroke at Higher Altitudes in Switzerland

Background—Studies assessing the effect of altitude on cardiovascular disease have provided conflicting results. Most studies were limited because of the heterogeneity of the population, their ecological design, or both. In addition, effects of place of birth were rarely considered. Here, we examine mortality from coronary heart disease and stroke in relation to the altitude of the place of res...

Rates of Concussion Are Lower in National Football League Games Played at Higher Altitudes

W hile concussions occur in nearly every sport and level of competition, the greatest frequency occurs in collision and contact sports such as football, lacrosse, hockey, rugby, soccer, and basketball.16,22,27 Specifically with regard to football, attempts at player-safety improvements for concussion prevention date back to the implementation of helmets by the National Football League (NFL) in ...

Rates of concussion are lower in National Football League games played at higher altitudes.

STUDY DESIGN Retrospective epidemiologic investigation. OBJECTIVE To investigate the relationship between altitude and concussion rate in the National Football League (NFL). Because of the physiologic responses that occur during acclimatization to altitude, it was hypothesized that games played on fields at a higher altitude would have reduced concussion rates compared to games played on fiel...

Response of the chydorid faunas to rapid climatic changes in four alpine lakes at different altitudes

The subfossil assemblages of Chydoridae from Late Glacial/Preboreal sediments of four sites from 603 m to 2290 m asl were analysed to trace the community response to rapid climatic warming that occurred at this period of time. In each site, distinct signals at the Younger Dryas/Preboreal boundary were recorded by density of remains, species diversity or community composition. However, responses...
