Revised Framingham Stroke Risk Score, Nontraditional Risk Markers, and Incident Stroke in a Multiethnic Cohort Clinical Sciences
Conclusions—The R-FSRS downgraded stroke risk but had better calibration and discriminative ability for incident stroke compared with the original FSRS. Nontraditional risk markers modestly improved the discriminative ability of the R-FSRS, with coronary artery calcium performing the best.

Neuroimaging, serum biomarkers, and patient characteristics as predictors of upper limb functioning 12 weeks after acute stroke: an observational, prospective study.
CONCLUSION: ASPECTS score ≥ 8 within 24 hours and S100β protein < 140.5 ng/L at 48 hours predict better upper limb functioning, while advanced age predicts worse upper limb functioning 12 weeks after stroke. PMID: 30213243 [PubMed - as supplied by publisher]

Early Blood-Brain Barrier Disruption in Ischemic Stroke Initiates Multifocally Around Capillaries/Venules Basic Sciences
Conclusions—Early BBBD in focal cerebral ischemia initiates multifocally in the distal capillary and venular bed of the cerebral microvasculature. It is closely associated with perimicrovascular vasogenic edema and microglial activation and predicts the extent of final infarction.

Factors Influencing Quality of Life in Stroke Patients: Focus on Eating Habits
This study aimed to identify lifestyle factors about eating habits that may affect the quality of life (QOL) in elderly stroke patients. Methods: Fifty elderly patients with a first-ever stroke were enrolled. QOL was assessed by the Stroke and Aphasia QOL Scale-39-J. Lifestyle factors about eating habits were collected using questionnaires (Questions 1-17) for the intake of salt, calcium, magnesium, potassium, taurine, fiber, and protein, and the frequency of breakfast.

Human Milk Oligosaccharide 2 ′-Fucosyllactose Reduces Neurodegeneration in Stroke Brain
In conclusion, our data suggest that 2’-FL has neuroprotective action through inhibition of Ca++i, inflammation, and apoptosis. Posttreatment with 2 ’-FL facilitates neural repair in stroke brain.

Calcium Channel Subunit α2δ-1 as a Potential Biomarker Reflecting Illness Severity and Neuroinflammation in Patients with Acute Ischemic Stroke
Cerebral infarction (commonly known as ischemic stroke) is a leading cause of morbidity, mortality and disability worldwide. Activation of presynaptic voltage-gated calcium channels (VGCCs) and glutamate release plays a central role in neuronal necrosis after cerebral ischemia.1,2 Previous studies seemed to be encouraging that nimodipine, a dihydropyridine calcium channel antagonist, had a significant benefit in mortality and neurologic outcome in patients with mild stroke or within 12 hours of stroke, although there was still controversial.

Gut Microbiota in Ischemic Stroke: Role of Gut Bacteria-Derived Metabolites
AbstractIschemic stroke (IS) remains a leading cause of death and long-term disability globally. Several mechanisms including glutamate excitotoxicity, calcium overload, neuroinflammation, oxidative stress, mitochondrial damage, and apoptosis are known to be involved in the pathogenesis of IS, but the underlying pathophysiology mechanisms of IS are not fully clarified. During the past decade, gut microbiota were recognized as a key regulator to affect the health of the host either directly or via their metabolites. Recent studies indicate that gut bacterial dysbiosis is closely related to hypertension, diabetes, obesity, d...

Repurposing the KCa3.1 Blocker Senicapoc for Ischemic Stroke
AbstractSenicapoc, a small molecule inhibitor of the calcium-activated potassium channel KCa3.1, was safe and well-tolerated in clinical trials for sickle cell anemia. We previously reported proof-of-concept data suggesting that both pharmacological inhibition and genetic deletion of KCa3.1 reduces infarction and improves neurologic recovery in rodents by attenuating neuroinflammation. Here we evaluated the potential of repurposing senicapoc for ischemic stroke. In cultured microglia, senicapoc inhibited KCa3.1 currents with an IC50 of 7  nM, reduced Ca2+ signaling induced by the purinergic agonist ATP, suppressed express...

Effect of Inflammation on the Process of Stroke Rehabilitation and Poststroke Depression
Conclusions Stroke comprises ischemic stroke and ICH. The immuno-inflammatory process is involved in neural plasticity following events such as a hemorrhage or ischemic stroke. After ischemia, astrocytes, microglia, and MDMs play important roles during rehabilitation with the modulation of cytokines or chemokines, such as TNF-α and IL-1. Moreover, MiRNAs are also important posttranscriptional regulators in these glial mitochondrial responses to cerebral ischemia. ICH involves processes similar and different to those seen in ischemia, including neuronal injury, astrocytic and microglial/macrophage activation, and n...

Postreperfusion Blood Pressure Variability After Endovascular Thrombectomy Affects Outcomes in Acute Ischemic Stroke Patients With Poor Collateral Circulation
Conclusion: Postreperfusion BP management by decreasing BPV may have influence on improving clinical outcome in cases of poor collateral circulation among patients achieving successful recanalization after ERT. Introduction Endovascular recanalization therapy (ERT) has been adopted as standard stroke care in patients with acute ischemic stroke (1–6). Time to recanalization and degree of recanalization are the most important predictors of clinical outcomes after ERT (7). Before recanalization, an effort to reduce the time from symptom onset to reperfusion is critical for penumbral salvage. After recanalization...

Using Dental Pulp Stem Cells for Stroke Therapy
Conclusion and Future Perspectives Stem cell-based therapy is a promising alternative for stroke treatment. While stem cells from different sources, including induced PSC, ESC, MSC, and NSC, have been investigated, using NSC and enhancing the natural mechanisms is most appropriate for brain repair. In preclinical models of stroke, stem cell transplantation has led to positive outcomes through a variety of cellular and molecular mechanisms, many being mediated by the array of beneficial factors produced by the cells. Recent advances in cellular reprogramming have provided alternative sources of NSC to be investigated, allo...

Shengui Sansheng San Ameliorates Cerebral Energy Deficiency via Citrate Cycle After Ischemic Stroke
Conclusion In summary, SSS extraction significantly ameliorates cerebral energy metabolism via boosting citrate cycle, which mainly embodies the enhancements of blood glucose concentration, glucose and lactate transportation and glucose utilization, as well as the regulations of relative enzymes activities in citrate cycle. These ameliorations ultimately resulted in numerous ATP yield after stroke, which improved neurological function and infarcted volume. Collectively, it suggests that SSS extraction has exerted advantageous effect in the treatment of cerebral ischemia. Ethics Statement All animal operations were accor...

How People With Diabetes Can Lower Stroke Risk
After spending nearly two decades trying to manage her Type 2 diabetes, Agnes Czuchlewski landed in the emergency room in 2015, with news that she’d just experienced a heart attack. She also learned that she had metabolic syndrome, a cluster of conditions that includes diabetes but also brings higher risk of heart disease and stroke. “Because I needed to lose quite a bit of weight when I was first diagnosed, I was focused on the number I saw on the scale, and then on my blood-sugar numbers,” recalls Czuchlewski, 68, who lives in New York City. “I didn’t realize other numbers came into play, li...
