Review Meta Analysis
Intensive blood pressure reduction in acute intracerebral hemorrhage: a meta-analysis.
The aim of the present systematic review and meta-analysis was to evaluate the safety and efficacy of intensive blood pressure (BP) reduction in patients with acute-onset intracerebral hemorrhage (ICH) using data from randomized controlled trials. ⋯ Our findings indicate that intensive BP management in patients with acute ICH is safe. Fewer intensively treated patients had unfavorable 3-month functional outcome although this finding did not reach significance. Moreover, intensive BP reduction appears to be associated with a greater attenuation of absolute hematoma growth at 24 hours.

Recently, 2 independent studies reported that a rare missense variant, rs75932628 (R47H), in exon 2 of the gene encoding the "triggering receptor expressed on myeloid cells 2" (TREM2) significantly increases the risk of Alzheimer disease (AD) with an effect size comparable to that of the APOE ε4 allele. ⋯ While our results serve to confirm the association between R47H and risk of AD, the observed effect on risk was substantially smaller than that previously reported.
