Systemic thrombolysis for acute central retinal artery occlusion in sickle cell disease: Case report
We describe a 42-year-old African- American man with SCD (HbSS) who presented with an acute central retinal artery occlusion (CRAO) within an hour of onset and subsequently received IV thrombolysis with alteplase. His labs were significant for HbS 91%. He had no central vascular access to undergo emergent red blood cell (RBC) exchange so interventional radiology was consulted to minimize his bleeding risk after receiving tissue plasminogen activator (tPA). A right internal jugular catheter was placed with fluoro-guidance, resulting in minimal blood loss. After two sessions of RBC exchange, his HbS decreased to 26%. He repo...

Rate of strokes 1  year after retinal artery occlusion with analysis of risk groups.
CONCLUSION:: The number of strokes/transitory ischemic attacks within the first year is relatively low after retinal artery occlusion and patients that already had a previous stroke, transitory ischemic attack, and/or amaurosis fugax before retinal artery occlusion seem to have a higher risk for a cerebrovascular event after retinal artery occlusion.

Reduction of Leukocyte Microvascular Adherence and Preservation of Blood-Brain Barrier Function by Superoxide-Lowering Therapies in a Piglet Model of Neonatal Asphyxia
Conclusion: Using three different strategies to either prevent formation or enhance elimination of O2⋅_ during the post-asphyxial period, we saw both reduced leukocyte adherence and preserved BBB function with treatment. These findings suggest that agents which lower O2⋅_ in brain may be attractive new therapeutic interventions for the protection of the neonatal brain following asphyxia. Introduction Asphyxia is a relatively common source of neonatal brain damage (1), affecting ~2 in every 1,000 births (2). The hypoxic ischemia resulting from this oxygen deprivation can produ...

Effects of Nutritional Supplements and Dietary Interventions on Cardiovascular Outcomes: An Umbrella Review and Evidence Map.
Conclusion: Reduced salt intake, omega-3 LC-PUFA use, and folate supplementation could reduce risk for some cardiovascular outcomes in adults. Combined calcium plus vitamin D might increase risk for stroke. Primary Funding Source: None. PMID: 31284304 [PubMed - as supplied by publisher]

Retinal Vascular Signs and Cerebrovascular Diseases
Conclusions: There is extensive and increasing evidence that a range of retinal vascular signs and disease are closely linked to CeVD, including subclinical and clinical CeVD. New technology including AI-DL will allow further translation to clinical utilization.

Thrombolysis for Central Retinal Artery Occlusion in 2020: Time Is Vision!
Conclusions: In 2020, nonarteritic CRAO patients should theoretically receive the same thrombolytic therapies, in the same time window, as patients with acute cerebral ischemia. Eye stroke and teleeye stroke code encounters must include an expert ophthalmologic evaluation to confirm the correct diagnosis and to evaluate for ocular signs that may help guide IV tPA administration or IA management. Future research should focus on developing feasible retinal penumbra imaging studies that, similar to cerebral tissue viability or perfusion imaging, can be incorporated into the thrombolysis decision-making algorithm.

Use of Non-Vitamin  K Antagonist Oral Anticoagulants Among Patients with Nonvalvular Atrial Fibrillation and Multimorbidity
ConclusionsAmong patients with NVAF and six or more comorbid conditions, NOACs were associated with varying risk of stroke/SE and MB compared to warfarin and to each other. Rather than a “one drug fits all” approach, our results may be useful for appropriate OAC treatment for multimorbid patients.

Peptide5 attenuates rtPA related brain microvascular endothelial cells reperfusion injury via the Wnt/ β-catenin signalling pathway
CONCLUSION: This study showed that the application of peptide5 maintained cell viability and permeability associated with rtPA treatment, revealing a possible pathway that could be exploited to limit rtPA-related endothelial cell injury during ischemic stroke. Furthermore, the altered Wnt/β-catenin signaling pathway demonstrated that signaling pathways associated with Cx43 might have potential applications in the future. This study may provide a new way to attenuate HT and assist the application of rtPA in ischemic stroke.PMID:34370635 | DOI:10.2174/1567202618666210809115305
