Background/aims: Hippocampal atrophy has been identified as marker for the development of Alzheimer's dementia (AD). To what extent vascular risk factors and white matter hyperintensities (WMH) affect hippocampal volume (HV) in asymptomatic elderly subjects and thus may impact such a predictive capacity is controversial.
Methods: We analysed 287 participants of the Austrian Stroke Prevention Study (mean age 66.6 ± 6.6 years) with a Mini Mental State Examination score ≥27 who were free of neuropsychiatric disease and had undergone MRI including coronal T(1)-weighted sequences allowing for semi-automatic assessment of HV. Global brain volume (BV) was measured using SIENAX. WMH were rated according to the Fazekas scale and segmented to obtain WMH volumes.
Results: Higher age was associated with lower absolute and normalized HV, a lower BV and higher WMH volume. None of the vascular risk factors had an impact on HV except for high-density lipoprotein. This effect disappeared after normalization of HV. WMH severity and volume did not affect HV either.
Conclusion: Our data indicate HV loss in parallel with the whole brain and suggest no specific vulnerability towards vascular risk factors or age-related WMH in a cognitively intact normal elderly population. This also supports the utility of HV measurements to identify impending AD.

Hydroxychloroquine (HCQ), a synthetic antimalarial, is recognized for its immunomodulatory, anti-inflammatory and vascular-protective effects. In 20-30% of cases of primary obstetrical antiphospholipid syndrome (APS), the combination of antiplatelet aggregation and prophylactic anticoagulation fails to prevent obstetrical complications, a situation referred to as refractory obstetrical APS. This is partly due to the pro-inflammatory effects of antiphospholipid antibodies (aPL) binding to decidual and trophoblastic cells, which compromise embryonic implantation and placentation.

Objectives: Our objective was to determine risk factors and operative outcomes for patients with upper extremity penetrating vascular injuries(UEPVI).
Methods: A retrospective review was performed of all adult UEPVI patients presenting to a level I trauma center between 1986 and 2019. Statistical analyses were performed to determine the independent predictors of mortality and hospital length of stay(LOS) among patients who underwent operative repair.

Background: Endovascular aneurysm repair (EVAR) has become increasingly prevalent for treating asymptomatic abdominal aortic aneurysms (AAA). This study compares the early and late outcomes between EVAR and open aneurysm repair (OAR) in asymptomatic AAA patients.
Methods: A retrospective observational cohort study was conducted involving 564 patients (445 EVAR, 119 OAR) who underwent AAA repair from January 2010 to June 2022.

Objectives: The COVID-19 epidemic introduced significant systems- and disease-based uncertainty into Abdominal Aortic Aneurysm (AAA) rupture management. The goal of this work was to evaluate whether short-term AAA rupture outcomes during COVID-19 were comparable to pre-COVID era outcomes and to explore the impact of COVID status and COVID era healthcare systems restrictions on AAA rupture outcomes.
Methods: The Vascular Quality Initiative (VQI) database was queried for all ruptured AAAs that underwent intervention from January 1, 2019 to August 31, 2022.
