Influence of intracerebral hemorrhage location on incidence, characteristics, and outcome: population-based study.

چکیده
BACKGROUND AND PURPOSE The characteristics of intracerebral hemorrhage (ICH) may vary by ICH location because of differences in the distribution of underlying cerebral small vessel diseases. Therefore, we investigated the incidence, characteristics, and outcome of lobar and nonlobar ICH. METHODS In a population-based, prospective inception cohort study of ICH, we used multiple overlapping sources of case ascertainment and follow-up to identify and validate ICH diagnoses in 2010 to 2011 in an adult population of 695 335. RESULTS There were 128 participants with first-ever primary ICH. The overall incidence of lobar ICH was similar to nonlobar ICH (9.8 [95% confidence interval, 7.7-12.4] versus 8.6 [95% confidence interval, 6.7-11.1] per 100 000 adults/y). At baseline, adults with lobar ICH were more likely to have preceding dementia (21% versus 5%; P=0.01), lower Glasgow Coma Scale scores (median, 13 versus 14; P=0.03), larger ICHs (median, 38 versus 11 mL; P<0.001), subarachnoid extension (57% versus 5%; P<0.001), and subdural extension (15% versus 3%; P=0.02) than those with nonlobar ICH. One-year case fatality was lower after lobar ICH than after nonlobar ICH (adjusted odds ratio for death at 1 year: lobar versus nonlobar ICH 0.21; 95% confidence interval, 0.07-0.63; P=0.006, after adjustment for known predictors of outcome). There were 4 recurrent ICHs, which occurred exclusively in survivors of lobar ICH (annual risk of recurrent ICH after lobar ICH, 11.8%; 95% confidence interval, 4.6%-28.5% versus 0% after nonlobar ICH; log-rank P=0.04). CONCLUSIONS The baseline characteristics and outcome of lobar ICH differ from other locations.

Trends in the incidence and survival of intracerebral hemorrhage by its location in a Japanese community.
BACKGROUND No previous population-based studies have examined secular trends in the incidence of intracerebral hemorrhage (ICH) by its location. METHODS AND RESULTS We established 3 cohorts consisting of residents of Hisayama, Japan, aged ≥40 years without a history of stroke or myocardial infarction in 1961 (the first cohort, n=1,618), in 1974 (the second cohort, n=2,038), and in 1988 (the ...

Predictors of 30-day mortality in patients with spontaneous primary intracerebral hemorrhage
BACKGROUND Intracerebral hemorrhage (ICH) is a life threatening entity, and an early outcome assessment is mandatory for optimizing therapeutic efforts. METHODS We retrospectively analyzed data from 342 patients with spontaneous primary ICH to evaluate possible predictors of 30-day mortality considering clinical, radiological, and therapeutical parameters. We also applied three widely accepte...
متن کاملP84: Effect of Insulin-Like Growth Factor 2 (IGF2) as a Microglia-Derived Anti-Iinflammatory Ccytokine on Improving Memory Impairment Following Hippocampal Intracerebral Hemorrhage in Rat
Insulin-like growth factor 2 (IGF2) as a microglia-derived anti-inflammatory cytokine has a pivotal activity in memory consolidation. However, there is limited evidence on brain cell-originated IGF2 expression, regulation and function in pathological condition and neuro-inflammation. Hence, the present study was conducted to investigate the effect of IGF2 on improving the memory impairment in a...
