A patient examined > 6 hours after ictus who has a hematoma volume < 25 cm3 is unlikely to experience further hematoma growth. Prevention of brain infarction and premorbid management of liver disease may serve to lower the risk of hematoma enlargement. Although it remains controversial whether antihypertensive drugs should be used in the acute phase of intracerebral hemorrhage, poorly controlled diabetics with high systolic blood pressure (> or = 200 mm Hg) on admission also were at high risk of hematoma enlargement.

We use numerical simulations to probe the dynamics of concentrated suspensions of spherical microswimmers interacting hydrodynamically. Previous work in the dilute limit predicted orientational instabilities of aligned suspensions for both pusher and puller swimmers, which we confirm computationally. Unlike previous work, we show that isotropic suspensions of spherical swimmers are also always unstable. Both types of initial conditions develop long-time polar order, of a nature which depends on the hydrodynamic signature of the swimmer but very weakly on the volume fraction up to very high volume fractions.
