AI Article Synopsis
- The study investigates the expression profiles of circular RNAs (circRNAs) in patients with intracerebral hemorrhage (ICH) using RNA sequencing and RT-PCR across two cohorts.
- Researchers found 125 and 284 differentially expressed circRNAs in ICH patients compared to healthy controls in the discovery and validation cohorts, respectively, with nine circRNAs consistently altered.
- The circRNAs hsa_circ_0005505, circERBB2, and circCHST12 showed high potential as biomarkers for diagnosing ICH, with strong sensitivity and specificity when combined with ICH risk factors.
Article Abstract
Background: The roles and potential diagnostic value of circRNAs in intracerebral hemorrhage (ICH) remain elusive.
Methods: This study aims to investigate the expression profiles of circRNAs by RNA sequencing and RT-PCR in a discovery cohort and an independent validation cohort. Bioinformatics analysis was performed to identify the potential functions of circRNA host genes. Machine learning classification models were used to assess circRNAs as potential biomarkers of ICH.
Results: A total of 125 and 284 differentially expressed circRNAs (fold change > 1.5 and FDR < 0.05) were found between ICH patients and healthy controls in the discovery and validation cohorts, respectively. Nine circRNAs were consistently altered in ICH patients compared to healthy controls. The combination of the novel circERBB2 and circCHST12 in ICH patients and healthy controls showed an area under the curve of 0.917 (95% CI: 0.869-0.965), with a sensitivity of 87.5% and a specificity of 82%. In combination with ICH risk factors, circRNAs improved the performance in discriminating ICH patients from healthy controls. Together with hsa_circ_0005505, two novel circRNAs for differentiating between patients with ICH and healthy controls showed an AUC of 0.946 (95% CI: 0.910-0.982), with a sensitivity of 89.1% and a specificity of 86%.
Conclusion: We provided a transcriptome-wide overview of aberrantly expressed circRNAs in ICH patients and identified hsa_circ_0005505 and novel circERBB2 and circCHST12 as potential biomarkers for diagnosing ICH.

The effect of sarpogrelate compared to aspirin in high- or very-high-risk diabetes for primary prevention.

The benefit of aspirin in primary prevention for atherosclerotic cardiovascular diseases (ASCVD) is questionable due to bleeding complications. We analyzed the Korean National Health Insurance data to compare the efficacy and overall bleeding of sarpogrelate, an antiplatelet agent with lower bleeding risk, versus aspirin in high-/very-high-risk diabetic populations without prior ASCVD. The primary endpoint was net adverse clinical events (NACE), defined as a composite of efficacy and overall bleeding.

Background: Computed tomography angiography of the head (CTAH) is not routinely obtained during the initial evaluation of patients with traumatic intracranial hemorrhage (ICH); however, it is useful for diagnosing vascular pathologies that may have led to the bleed. The aims of this study were to identify traumatic ICH patient characteristics on presentation that are associated with positive CTAH findings to elucidate which ones should prompt a CTAH and compare outcomes of patients with positive and negative CTAH findings.
Methods: This is a retrospective cohort study of 522 patients who had blunt traumatic ICH and subsequently received CTAH between January 1, 2017, and January 1, 2022.

Aim: (i) To explore the attitudes of patients with atrial fibrillation (AF) towards oral anti-coagulation (OAC) for stroke prevention post-intracerebral haemorrhage (ICH) and (ii) to explore factors that influence patients' decision-making process for stroke prevention.
Methods And Results: Patients with documented diagnosis of AF and history of a non-traumatic ICH, who were eligible for long-term OAC were recruited from eight hospitals in England, using purposive sampling. Data were collected using semi-structured interviews and analysed using Framework analysis.

Background: Selpercatinib, a selective RET kinase inhibitor, is approved for treating various cancers with RET gene mutations such as RET-rearranged thyroid cancer and non-small cell lung cancer. The presence of process-related and degradation impurities in its active pharmaceutical ingredient (API) can significantly affect its safety and effectiveness. However, research on detecting these impurities is limited.

Patients with intracranial aneurysms (IA) undergoing endovascular treatment face varying risks and benefits when tirofiban is used for thromboprophylaxis during surgery. Currently, there is a lack of high-level evidence summarizing this information. This study aims to conduct a systematic review and meta-analysis to evaluate the efficacy and safety of tirofiban during endovascular treatment of IA.
