To search for novel transcriptional pathways that are activated in abdominal aortic aneurysm rupture, cDNA microarrays were used to compare global mRNA expression at the aneurysm rupture edge to anterior sac, and selected results were confirmed using quantitative real-time-polymerase chain reaction (QRT-PCR). This study identified apoptosis, angiogenesis, and inflammation as potentially important participants during the process of aneurysm rupture.

The oral microbiota: new insight into intracranial aneurysms.
Ann Med

Department of Neurointervention, The First Affiliated Hospital of Zhengzhou University, Zhengzhou, China.
Background: Intracranial aneurysms (IAs) are a significant clinical concern, with detection rates increasing due to advances in imaging technologies. However, precise mechanisms underlying their pathophysiology remain incompletely understood. Recent evidence suggests a pivotal role of oral microbiota dysbiosis, particularly periodontal pathogens, in systemic inflammation that may contribute to IA development and rupture.

Introduction A large majority of spontaneous subarachnoid hemorrhages (SAH) are attributed to aneurysm rupture, though the cause remains unknown in a notable percentage of cases. Non-aneurysmal SAH (naSAH) is generally thought to follow a more benign clinical course than aneurysmal SAH (aSAH); however, similar complications may occur, and poor outcomes are still possible. Given the limited research on naSAH, this study aims to characterize these patients and correlate clinical and radiographic findings with outcomes.

Background: There are sex disparities in the risk of ruptured intracranial aneurysm (IA), but which sex-specific factors are related to ruptured IA remains inconclusive.
Methods: Data from electronic medical records from two tertiary hospitals, collected between January 2012 and December 2019, were analyzed for this study. All IAs were confirmed by computed tomographic angiography or digital subtraction angiography.

Objective: Post-repair surveillance of ruptured abdominal aortic aneurysm (rAAA) is critical for detecting potential complications. Substantial loss to follow-up has been reported in populations undergoing elective endovascular aortic repair (EVAR); however, there is limited data on follow-up rate among patients presenting with rupture. Thus, we investigated follow-up trends and factors influencing retention at a major academic referral center with a wide service area.
View Article and Find Full Text PDFBackground: The rupture of intracranial aneurysms (IAs) leads to aneurysmal subarachnoid hemorrhage (aSAH), which is associated with significant disability and mortality rates. This study aims to identify metabolic markers causally linked to the occurrence of IAs and aSAH through Mendelian randomization (MR), thereby offering novel predictive and therapeutic targets.
Methods: We conducted a genome-wide association study (GWAS) on IAs and aSAH, analyzing 1,400 metabolomic indices from the Canadian Longitudinal Study on Aging (CLSA) cohort (n = 8,299).
