20 09 Diameter of Reduced Words

For finite reflection groups of types A and B, we determine the diameter of the graph whose vertices are reduced words for the longest element and whose edges are braid relations. This is deduced from a more general theorem that applies to supersolvable hyperplane arrangements.

Neighborhood cohesion is associated with reduced risk of stroke mortality.

BACKGROUND AND PURPOSE Greater social cohesion is related to lower rates of coronary heart disease, but its relation to stroke risk is unstudied. This study examined whether neighborhood social cohesion was protective against stroke mortality and incidence. METHODS Data come from 5789 participants (60% female; 62% black; mean age, 74.7 years) in a longitudinal study of chronic diseases in the...

Reduced Stroke Risk After Parathyroidectomy in End-Stage Renal Disease

Research information on the risk of stroke in patients with dialysis-dependent end-stage renal disease (ESRD) who have undergone parathyroidectomy (PTX) is scant. We used a nationwide health insurance claims database to select all patients with dialysis-dependent ESRD age 18 years and older for the study population. Of the patients with ESRD, we selected 1083 patients who had undergone PTX betw...

Influenza vaccination is associated with a reduced risk of stroke.

BACKGROUND AND PURPOSE Vascular death rates and hospitalizations for stroke are increased during influenza epidemics. Influenza vaccination may prevent stroke. We investigated whether influenza vaccination is associated independently with reduced odds of stroke and whether effects are confined to stroke subgroups and winter seasons and shared by other vaccinations. METHODS During 18 months, w...
