Aggressive LDL-C Lowering and the Brain: Impact on Risk for Dementia and Hemorrhagic Stroke: A Scientific Statement From the American Heart Association
The objective of this scientific statement is to evaluate contemporary evidence that either supports or refutes the conclusion that aggressive low-density lipoprotein cholesterol lowering or lipid lowering exerts toxic effects on the brain, leading to cognitive impairment or dementia or hemorrhagic stroke. The writing group used literature reviews, references to published clinical and epidemiology studies, clinical and public health guidelines, authoritative statements, and expert opinion to summarize existing evidence and to identify gaps in current knowledge. Although some retrospective, case control, and prospective lon...

Functional effects of haemoglobin can be rescued by haptoglobin in an in vitro model of subarachnoid haemorrhage
Subarachnoid haemorrhage causes significant cognitive and functional disability in survivors, and one contributing factor is exposure of neurons to haemoglobin causing cell loss and dysfunction. In this in vitro subarachnoid haemorrhage model, haemolysate application to cultured neurons impairs cytoskeletal integrity. Furthermore, amplitude of AMPA receptor-mediated synaptic currents is reduced by haemolysate, driven by reduction in GluA1 expression. These deficits can be prevented with application of exogenous haptoglobin without off-target effects. These results provide new insight into neuronal dysfunction in haemorrhag...

Selecting stroke patients for thrombectomy: is CTA+ASPECTS enough?
Since 2014, a series of randomised controlled trails (RCTs) have demonstrated the benefit of endovascular thrombectomy (EVT) on functional outcome for the participants who had acute ischaemic stroke (AIS) with occlusion of a proximal intracranial artery in the anterior circulation. The characteristics of the people enrolled in these RCTs have been used to define recommended criteria to select patients for thrombectomy in clinical practice. The initial group of RCTs largely enrolled participants early after AIS (mostly under 6 hours) who had National Institutes of Health stroke scale scores ≥6 (range 0–42 with lowe...

Endovascular treatment for large-core ischaemic stroke: a meta-analysis of randomised controlled clinical trials
Conclusion EVT appears to be effective and safe and may be considered for the treatment of large-core AIS, as assessed by ASPECTS of 2–5 or volumetric methods. PROSPERO registration number CRD42022334417.

Prediction of stress-related gastrointestinal bleeding in patients with aneurysmal subarachnoid hemorrhage using caudate Hounsfield unit value in ASPECT score
ConclusionAmong aSAH patients, lower right caudate HU values indicated a higher risk of developing SRGB. Our findings provide further evidence for the relationship between the gastrointestinal system and the brain.

Vitamin E supplementation (alone or with other antioxidants) and stroke: a meta-analysis
CONCLUSIONS: Supplementation with vitamin E alone is not associated with stroke reduction. Instead, supplementation of vitamin E with other antioxidants reduces the incidence of ischemic stroke but increases the risk of hemorrhagic stroke, cancelling any beneficial effect derived. Thus, vitamin E is not recommended in stroke prevention.SYSTEMATIC REVIEW REGISTRATION: PROSPERO registration no. CRD42022258259.PMID:37698992 | DOI:10.1093/nutrit/nuad114

Galectin-3 promotes brain injury by modulating the phenotype of microglia via binding TLR-4 after intracerebral hemorrhage
CONCLUSIONS: This study proves that Gal-3 is involved in neuroinflammation and nerve damage after ICH. Gal-3 expression should not be encouraged early on to prevent neuroinflammation. which provides a new possibility for clinical treatment for ICH patients.PMID:37698533 | DOI:10.18632/aging.205014

Direct oral anticoagulants versus vitamin K antagonists: Which one is more effective in atrial fibrillation
CONCLUSIONS: Our meta-analysis demonstrates that in patients undergoing bioprosthetic valve surgery and presenting with AF afterward, DOAC and VKA are similar regarding life-threatening and all-cause mortality outcomes, including major bleeding, stroke, and intracranial hemorrhage.PMID:37697799 | DOI:10.1177/02676591231202383

Intracerebral Hemorrhage Among Blood Donors and Their Transfusion Recipients
CONCLUSIONS AND RELEVANCE: In an exploratory analysis of patients who received red blood cell transfusions, patients who underwent transfusion with red blood cells from donors who later developed multiple spontaneous ICHs were at significantly increased risk of spontaneous ICH themselves. This may suggest a transfusion-transmissible agent associated with some types of spontaneous ICH, although the findings may be susceptible to selection bias and residual confounding, and further research is needed to investigate if transfusion transmission of cerebral amyloid angiopathy might explain this association.PMID:37698562 | DOI:1...
