Introduction: Little is known regarding long-term stroke outcomes in patients with substance use disorder (SUD). Based on anecdotal data, some individuals use illicit drugs, particularly opioids, in an attempt to reduce stroke mortality, disability, or recurrence. This study is aimed to assess the effect of SUD on stroke outcomes.
Methods: Patients were recruited from the Mashhad Stroke Incidence Study, a population-based study of stroke in Iran. For a period of 1 year, all patients with first-ever stroke (FES) were recruited and then followed up for the next 5 years. Disability and functional dependency were defined using modified Rankin Scale (>2) and Barthel Index (<60), respectively. We compared the cumulative rates of mortality in follow-up points using the log-rank test. We used multivariable logistic, Cox regression and competing risk models to assess adjusted hazard ratio (aHR) with 95% confidence interval (CI) of stroke disability, functional dependency, mortality, and recurrence among those with a history of SUD.
Results: 595 FES patients (mean age of 64.6 ± 14.8 years) were recruited in this study. Eighty-one (13.6%) were current substance users, including opium (n = 68), naswar (n = 5, 6.1%), hashish (n = 1), heroin (n = 1), and (n = 7) others. The frequency of vascular risk factors was similar between the SUD and non-SUD groups, except for a higher rate of cigarette smoking in the SUD group (p < 0.001). After adjusting for various sociodemographic variables, vascular risk factors, and the severity of stroke at admission, SUD increased the 3-month (aHR: 1.60, CI: 1.01-2.49), 1-year (aHR: 1.73, CI: 1.20-2.65), and 5-year (aHR: 1.72, CI: 1.23-2.35) poststroke mortality risk. We did not observe a significant change in the risk of stroke recurrence, disability, and functional dependency in those with a history of SUD.
Conclusion: SUD increased the hazard ratio of stroke mortality with no effect on the disability rate. The public should be advised about the potential harm of substance abuse.

Background: Patent foramen ovale (PFO) has been identified as a potential risk factor for cryptogenic stroke (CS). Although transesophageal echocardiography (TEE) is considered the gold standard for PFO detection, false-negative results remain a clinical concern, particularly in CS patients with high suspicion of PFO-related etiology.
Aims: To evaluate the clinical utility of transcatheter PFO exploration (TPFOE) in CS patients with negative TEE findings but high suspicion of PFO-related etiology.

Spinal muscular atrophy (SMA) is a neurodegenerative disease caused by ubiquitous deficiency in the SMN protein. The identification of disease modifiers is key to understanding pathogenic mechanisms and broadening the range of targets for developing SMA therapies that complement SMN upregulation. Here, we report a cell-based screen that identified inhibitors of p38 mitogen-activated protein kinase (p38 MAPK) as suppressors of proliferation defects induced by SMN deficiency in mouse fibroblasts.

Background: protamine sulfate is used to reduce bleeding risk after Carotid Artery Stenting (CAS), but its efficacy in personalized patient settings remains underexplored. This study aims to identify factors associated with greater benefits from protamine sulfate following CAS.
Methods: A retrospective review of Vascular Quality Initiative (VQI) data (2016-2022) identified patients undergoing CAS, divided into Transfemoral CAS (TF-CAS) and Transcarotid artery revascularization (TCAR) groups.

Tool use is a complex motor planning problem. Prior research suggests that planning to use tools involves resolving competition between different tool-related action representations. We therefore reasoned that competition may also be exacerbated with tools for which the motions of the tool and the hand are incongruent (e.

Endovascular therapy (EVT) is standard care for acute ischemic stroke due to large vessel occlusion, but its availability is limited in areas with long distances. It has also been demonstrated that there are differences in the utilization of thrombectomy related to socioeconomic factors. The aim of this study is to examine regional differences in the utilization of mechanical thrombectomy and outcome within one comprehensive stroke center district in terms of distance and income.
