Background: Subarachnoid hemorrhage (SAH) is an uncommon disease. Considering ruptured intracranial aneurysms as the main cause of this disease and only a minority of the intracranial aneurysms will rupture sooner or later, to understand the underlying pathology or a specific gene expression profile of an impending ruptured intracranial aneurysm is of great importance.
Methods: The transcriptome in peripheral blood cells of patients with SAH from ruptured aneurysm was compared with that of control patients suffering from headaches. The microarray dataset GSE36791 comprised 43 patients with SAH from ruptured aneurysms and 18 control patients. Differential expression analysis was performed with the R language packages to identify differentially expressed genes (DEGs). Gene Ontology enrichment analysis and Kyoto Encyclopedia of Genes and Genomes pathway database analysis were performed to identify significantly altered biological functions and pathways, respectively. The protein-protein interaction networks were constructed with information from the STRING database.
Results: A total of 528 DEGs were identified, of which 311 were upregulated and 217 downregulated. Clustering analysis confirmed that these genes can distinguish ruptured aneurysm SAH patients from the control patients. The DEGs were mainly enriched for immune/inflammation response and related pathways. Among the DEGs, 8 genes (ARG1, MAPK14, RPS2, SPI1, FYN, CEBPB, FLOT1, and CD4) were identified as the key regulators in the Protein-Protein Interaction network. MAPK14, CEBPB, FLOT1, and CD4 might be potential biomarkers of SAH.
Conclusion: This study identified a range of DEGs SAH patients with ruptured aneurysms, which may enhance our current knowledge on this disease and may provide potential biomarkers of this disease.

Background: Granulomatosis with polyangiitis (GPA) is an autoimmune multisystem disorder characterized by small vessel vasculitis with granulomatous inflammation. In this report, we describe a unique case of GPA who presented with complete heart block (CHB) and developed complications due to intracranial large vessel involvement.
Case Summary: A 47-year-old gentleman presented with CHB with a background history of arthralgia and blood-tinged nasal discharge.

Although computed tomography (CT) is the diagnostic gold standard for acute subdural hematoma, the absence of clear trauma should prompt the use of computed tomography angiography (CTA) to identify potential underlying causes, such as ruptured aneurysms, which can significantly influence treatment decisions.

Background: Portal venous system aneurysms (PVA) are increasingly diagnosed on cross-sectional computed tomography (CT) imaging. However, the natural history of these aneurysms is poorly understood and reports are limited to small case series.
Methods: Terms relevant to PVA were searched in radiology reports (2010-2022) with PVA presence confirmed by manual review.

Background: We evaluated the outcomes of pediatric patients with blunt liver and spleen injury (BLSI) admitted to hospitals with pediatric intensive care units (PICUs).
Methods: A post-hoc analysis of a multicenter observational study on pediatric patients (≤16 years) with BLSI at 83 hospitals between 2008 and 2019 was conducted. Thirty-day mortality and BLSI-associated adverse events were compared between patients treated in hospitals with and without PICUs.

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.
