Are mesenchymal stem cells still effective in acute GvHD management?

Objective: Graft-versus-host disease (GvHD) is a common and serious complication following allogeneic hematopoietic stem cell transplantation (allo-HSCT), significantly impacting transplant efficacy. In the treatment of GvHD, numerous therapeutic approaches have been explored, with mesenchymal stem cells (MSCs) emerging as a prominent immunomodulatory option. We aimed to evaluate efficacy and outcomes of using MSCs for steroid refractory acute GVHD (SR-aGvHD) management.

Feasibility of platelet marker analysis in ischemic stroke patients and their association with one-year outcome. A pilot project within a subsample of the Stroke Induced Cardiac Failure in Mice and Men (SICFAIL) cohort study.

Patients with ischemic stroke (IS) are at increased risk of mortality and recurrent cerebro- or cardiovascular events. Determining prognosis after IS remains challenging but blood-based biomarkers might provide additional prognostic information. As platelets are crucially involved in the pathophysiology of vascular diseases, platelet surface proteins (PSP) are promising candidates as prognostic markers in the hyperacute stage.

CD84 Links T Cell and Platelet Activity in Cerebral Thrombo-Inflammation in Acute Stroke.

Rationale: Ischemic stroke is a leading cause of morbidity and mortality worldwide. Recanalization of the occluded vessel is essential but not sufficient to guarantee brain salvage. Experimental and clinical data suggest that infarcts often develop further due to a thromboinflammatory process critically involving platelets and T cells, but the underlying mechanisms are unknown.

Should IV Thrombolysis be given in Patients with Suspected Ischemic Stroke but Unknown Symptom Onset and Without Diffusion-Weighted Imaging Lesion? - Results of a Case-Control Study.

Background: Many acute ischemic stroke (AIS) patients present with unknown time of symptom onset (UTO). In these situations, wake-up MRI protocols can guide treatment decisions: patients with DWI (diffusion-weighted imaging) but no fluid-attenuated inversion recovery lesion were shown to benefit from IVT (intravenous thrombolysis). However, initial MRI of some stroke patients is DWI negative, leaving it unclear whether this subgroup profits from IVT.
