Ischemic stroke, a leading cause of mortality, results in severe neurological outcomes in the patients. Effective stroke therapies may significantly decrease the extent of injury. For this purpose, novel and efficient drug delivery strategies need to be developed. Among a myriad of therapeutic and drug delivery techniques, exosomes have shown promising results in ischemic stroke either by their intrinsic therapeutic characteristics, which can result in angiogenesis and neurogenesis or by acting as competent, biocompatible drug delivery vehicles to transport neurotherapeutic agents into the brain. In this review, we have discussed different methods of exosome isolation and cargo loading techniques, advantages and disadvantages of using exosomes as a drug delivery carrier and the therapeutic applications of exosomes with a focus on ischemic stroke therapy.

Introduction: Spondyloepimetaphyseal dysplasia with joint laxity type 1 (SEMD-JL1) is an extremely rare skeletal dysplasia belonging to a group of disorders called linkeropathies. It is characterized by skeletal and connective tissue abnormalities. Biallelic variants in genes encoding enzymes that synthesize the tetrasaccharide linker region of glycosaminoglycans lead to linkeropathies, which exhibit clinical and phenotypic features that overlap with each other.

Background: We performed a prespecified subgroup analysis of the CATIS-2 trial (China Antihypertensive Trial in Acute Ischemic Stroke II) to compare the effect of early versus delayed antihypertensive treatment on death and disability in patients with and without medical history of hypertension.
Methods: CATIS-2 is a multicenter randomized clinical trial conducted in 106 hospitals in China. The trial randomized 4810 patients with acute ischemic stroke within 24 to 48 hours of symptom onset and elevated systolic blood pressure between 140 and <220 mm Hg to receive antihypertensive treatment immediately after randomization or to discontinue antihypertensive medications for 7 days and then receive treatment on day 8.
Usefulness of Myelin Quantification Using Synthetic Magnetic Resonance Imaging for Predicting Outcomes in Patients With Acute Ischemic Stroke.
Stroke

Department of Clinical Neuroscience and Therapeutics, Graduate School of Biomedical and Health Sciences, Hiroshima University, Japan (M.T., T.N., S.A., H.M.).
Background: Synthetic magnetic resonance imaging (MRI) is an innovative MRI technology that enables the acquisition of multiple quantitative values, including T1 and T2 values, proton density, and myelin volume, in a single scan. Although the usefulness of myelin measurement with synthetic MRI has been reported for assessing several diseases, investigations in patients with stroke have not been reported. We aimed to explore the utility of myelin quantification using synthetic MRI in predicting outcomes in patients with acute ischemic stroke.

Background: A minimum threshold activated clotting time (ACT) to guide heparin dosing during percutaneous coronary intervention (PCI) is associated with lower ischemic complications. However, data are variable regarding the risk of high ACT levels. The aim of this study was to assess the impact of peak procedural ACT on complications and mortality for transfemoral and transradial access PCI.

Objective: We sought to assess the impact of dietary risk on the worldwide burden of stroke, focusing specifically on ischemic stroke.
Methods: Utilizing information from the Global Burden of Disease Study 2021 (GBD2021), we evaluated the age-standardized death rate (ASDR), the age-standardized disability-adjusted life years (DALYs) rate, and the age, sex, and regional distribution of the estimated annual percentage change (EAPC) of the stroke burden linked to dietary risk from 1990 to 2021.
Results: The global overall ASDR and the age-standardized DALY rate per 100,000 population for stroke linked to dietary risk from 1990 to 2021 exhibited a declining trend [EAPC = -1.
