Ischemic stroke (IS) is a complex disease caused by an obstruction within a brain-supplying blood vessel that involves both genetic and environmental factors. In this study, we evaluated the association of genetic polymorphisms in the AHSG gene with ischemic stroke risk in the Chinese population. A case-control study was conducted that included 477 nephropathy patients and 490 healthy controls. Chi-squared tests and a genetic model were used to evaluate associations. In the genetic model analysis, we identified that the SNP of rs2070634 in the AHSG gene was associated with a 1.37-fold increase the risk of stroke in the co-dominant model (adjusted, the "G/T" genotype), and a 1.40-fold increase the risk of stroke in the Over-dominant model (adjusted, the "G/T" genotype), respectively. The rs2518136 in the AHSG gene was associated with a 1.37-fold increase the risk of stroke in the co-dominant model (adjusted, the "T/C" genotype) and a 1.41-fold decrease the risk of stroke in the over-dominant model (adjusted, the "T/C" genotype), respectively. We found four SNPs (rs2248690, rs2070634, rs4917 and rs2518136) show a strong linkage, but the AHSG haplotype was not found to be associated with a risk of ischemic stroke. The present study suggests that the AHSG polymorphism may contribute to an increased risk of ischemic stroke.

Background: There is still a significant population of patients with embolic stroke of Undetermined Source (ESUS) whose specific attributable cause of the stroke remains unknown.

Objectives: Our research aimed to assess clinical, electrocardiogram, laboratory, and echocardiographic parameters that may predict the propensity of paroxysmal atrial fibrillation (PAF).

Methods: We enrolled seventy-five ESUS patients who were in sinus rhythm at the time of stroke diagnosis to undergo in-hospital 7-day Holter monitoring, testing for Pro-BNP, and a standard echocardiographic examination.

Prognostic impact of one-year permanent pacemaker implantation after mitral valve surgery with the Cox-maze procedure.

Eur J Cardiothorac Surg

Department of Thoracic and Cardiovascular Surgery, Korea University Anam Hospital, Korea University College of Medicine, Seoul, Republic of Korea.

Objectives: This study aimed to evaluate the prognostic impact of permanent pacemaker (PPM) implantation within the first year after mitral valve (MV) surgery combined with the Cox-maze procedure, focusing on long-term outcomes, including overall mortality, infective endocarditis (IE), and ischaemic stroke.

Methods: We conducted a retrospective cohort study using data from the National Health Insurance Service (NHIS) in South Korea, identifying 10,127 patients who underwent MV surgery with the Cox-maze procedure between 2005 and 2020. Patients were classified into the PPM and non-PPM groups based on PPM implantation within one year postoperatively.

Regulatory T Cells for Stroke Recovery: A Promising Immune Therapeutic Strategy.

CNS Neurosci Ther

January 2025

Department of Research, Beijing Rehabilitation Hospital, Capital Medical University, Beijing, China.

Background: Stroke remains a leading cause of mortality and disability among adults. Given the restricted therapeutic window for intravascular interventions and neuroprotection during the acute phase, there has been a growing focus on tissue repair and functional recovery in the subacute and chronic phases after stroke. The pro-inflammatory microglial polarization occurs in subacute and chronic phases after stroke and may represent therapeutic targets for stroke recovery.

Behçet's disease (BD) is a rare systemic vasculitis that is characterized by recurrent oral and genital ulcers, uveitis, and skin lesions. Although neurological involvement is a known complication, ischemic stroke remains uncommon. Herein, we report a 37-year-old Kuwaiti woman who experienced recurrent ischemic stroke with no traditional risk factors.
