In SCA3, the risk of exposure to COVID-19, educational level, disease course and the severity of ataxia may be factors affecting patients' mental health. More attention should be paid to the mental health of SCA patients during the COVID-19 pandemic. APOE ε4 is independently associated with lobar intracranial hemorrhages (ICH). Although the ε4 allele enhances amyloid deposition in blood vessels, the ε2 allele predisposes to vasculopathic changes leading to rupture of amyloid laden vessels. Thus, ε4 and ε2 carriers might have increased susceptibility to ICH. We aimed to study the impact of the apolipoprotein E alleles in the development of symptomatic ICH (sICH). We included 384 consecutive ischemic anterior circulation stroke patients submitted to thrombolysis between January 2014 and March 2016. Admission CT-scans were reviewed to calculate the ASPECTS. Patients were followed for up to at least 6months post-stroke or until death. Outcome was development of sICH, defined according to the ECASS III. Considering APOE genotyping, three patients had ε2/ε2, four had ε2/ε4, 38 had ε2/ε3, 284 had ε3/ε3, 51 had ε3/ε4 and four had ε4/ε4. sICH was associated with sex and diabetes. In multivariate analysis, sICH was not associated with carrying one or more ε4 alleles (OR 0.483, 95%CI=[0.059, 3.939], p=0.497) nor with carrying one or more ε2 alleles (OR 1.369, 95%CI=[0.278, 6.734], p=0.699). No association was found between APOE genotype and the development of symptomatic intracranial hemorrhage. No association was found between APOE genotype and the development of symptomatic intracranial hemorrhage. Retrospective cohort study. This study was performed to evaluate the accuracy of cervical pedicle screw (CPS) placement with use of a navigated surgical drill (ND) and to compare it with navigated manual probe (MP) at C3-C6. 47 consecut
