Decline in cigarette smoking accelerated during Obama administration

The rate of cigarette smoking among U.S. adults has declined substantially during the presidency of Barack Obama, according an article published in the New England Journal of Medicine. Author Michael Fiore, MPH ’85, writes that since 2009, smoking rates have dropped about 0.78 percentage points per year and are now at 15.3%. If this rate of decline continues, smoking prevalence will fall to zero by around 2035.

Associations of specific types of sports and exercise with all-cause and cardiovascular-disease mortality

Tuesday, December 13th, 2016
Associations of specific types of sports and exercise with all-cause and cardiovascular-disease mortality: a cohort study of 80 306 British adults

“Results Significant reductions in all-cause mortality were observed for participation in

cycling (HR=0.85, 95% CI 0.76 to 0.95),

swimming (HR=0.72, 95% CI 0.65 to 0.80),

racquet sports (HR=0.53, 95% CI 0.40 to 0.69) and

aerobics (HR=0.73, 95% CI 0.63 to 0.85).

No significant associations were found for participation in football and running.

A significant reduction in CVD mortality was observed for participation in

swimming (HR=0.59, 95% CI 0.46 to 0.75),

racquet sports (HR=0.44, 95% CI 0.24 to 0.83) and

aerobics (HR=0.64, 95% CI 0.45 to 0.92), but there were

no significant associations for cycling, running and football.

Variable dose–response patterns between the exposure and the outcomes were found across the sport disciplines.”

Vision Impairment and Intracranial Pressure (VIIP) – 11.22.16

Vision Impairment and Intracranial Pressure (VIIP) – 11.22.16

Overview | Description | Applications | Operations | Results | Publications | ImageryISS Science for Everyone

Science Objectives for Everyone
The Vision Impairment and Intracranial Pressure (VIIP) project examined the effect of long-term exposure to microgravity on the structure of the eye along with change in distance and near vision of crew members before and after they returned to Earth.

Science Results for Everyone
I can see (less) clearly now. Many astronauts experience poorer vision after flight, some even for years after. A number of studies have looked for causes and distinct physical changes in the eye itself have been found. MRI scans suggest that pressure changes in the brain and spinal fluid caused by weightlessness may be partly to blame. Many astronauts do not show these effects, though, and more advanced imaging techniques may be needed to understand the role of changing brain pressure in microgravity. This in turn will help researchers assess vision problems and develop ways to prevent them.
