Arsenic, polycyclic aromatic hydrocarbons, and metal exposure and risk assessment of stroke
This study aimed to assess different arsenic species, including total arsenic; two types of organic arsenic, i.e., arsenobetaine and arsenocholine; four types of inorganic arsenic, i.e., arsenic acid, arsenous acid, dimethylarsinic acid (DMA), and monomethylarsonic acid (MMA); six types of urinary polycyclic aromatic hydrocarbon (PAH) compounds, i.e., 1-hydroxynaphthalene, 1-hydroxyphenanthrene, 1-hydroxypyrene, 2-hydroxynaphthalene, 2-hydroxyfluorene, and 3-hydroxyfluorene; and fourteen types of metals from urine specimen, i.e., manganese, cadmium, lead, mercury, barium, cobalt, strontium, molybdenum, cesium, thallium, an...

Neuroprotective Effects of a Cardioplegic Combination (Adenosine, Lidocaine, and Magnesium) in an Ischemic Stroke Model
We examined the effects of low-dose ALM on ischemic stroke in cell and animal models. Cobalt chloride (CoCl2) –treated SH-SY5Y cells were used as a surrogate model to mimic oxygen–glucose deprivation conditions. The cells were incubated with different dilutions of ALM authentic solution (1.0 mM adenosine, 2.0 mM lidocaine, and5 mM MgSO4 in Earle’s balanced salt solution). At a concentration of 2.5%, ALM significantly reduced CoCl2-induced cell loss. This protective effect persisted even when ALM was administered 1  h after the insult. We used transient middle cerebral artery occlusion to investigate the therapeuti...

Safety and efficacy of the surpass streamline for intracranial aneurysms (SESSIA): A multi-center US experience pooled analysis
CONCLUSION: This is the largest cohort study using a 72-96 wire flow diverter. The Surpass Streamline demonstrated a favorable safety and efficacy profile, making it a valuable option for treating not only large but also wide-necked small and medium-sized intracranial aneurysms.PMID:35934939 | DOI:10.1177/15910199221118148

Refractory in-stent stenosis after flow diverter stenting associated with delayed cobalt allergic reaction
In-stent stenosis (ISS) triggered by a metal-induced allergic reaction of Pipeline embolization device (PED) placement is extremely rare. The present report describes a patient who presented with delayed parent artery occlusion and refractory ISS after PED placement due to cobalt allergy. A patient in her 70s underwent PED placement for a right internal carotid artery (ICA) large aneurysm; 4 months later, the patient presented with left-sided hemiparesis, and MRI revealed right ICA occlusion even though antiplatelet therapy was optimal. She underwent mechanical thrombectomy, and successful recanalization was achieved. Howe...

Endothelin-1 (ET-1) Promotes a Proinflammatory Microglia Phenotype in Diabetic Conditions.
Abstract Diabetes increases the risk and severity of cognitive impairment, especially after ischemic stroke. It is also known that the activation of ET system is associated with cognitive impairment and microglia around periinfarct area produce ET-1. However, little is known about the effect of ET-1 on microglial polarization, especially under diabetic conditions. We hypothesized that a) ET-1 activates microglia to proinflammatory M-1 like phenotype, and b) Hypoxia/LPS activates the microglial ET system and promotes microglial activation towards M-1 phenotype in diabetic conditions. Microglial cells (C8B4) culture...

Details on the effect of very short dual antiplatelet therapy after drug-eluting stent implantation in patients with high bleeding risk: insight from the STOPDAPT-2 trial
In conclusion, the effects of 1-month DAPT for the primary and major secondary endpoints were consistent in HBR and non-HBR patients without any significant interactions. The benefit of 1-month DAPT in reducing major bleeding was numerically greater in HBR patients.Clinical trial registration Short and optimal duration of dual antiplatelet therapy after everolimus-eluting cobalt –chromium stent-2 [STOPDAPT-2]; NCT02619760.

ICDs Have Come a Long Way in 40 Years
Michel Mirowski and his colleagues gave the field of implantable cardioverter-defibrillators (ICDs) a pretty good start, but what's more impressive is how far the technology has advanced since that first human ICD implant in February 1980. In the past 40 years we've seen ICDs become dramatically smaller, longer lasting, more capable, more personalized, subcutaneous (non-transvenous), and even MRI-firendly. And that's not to mention the advanced data connectivity and monitoring capabilities that the latest technologies offer. So without further ado, let's take a look at the current ICD landscape and the companie...

Long-Term Safety and Efficacy of Durable Polymer Cobalt-Chromium Everolimus-Eluting Stents in Patients at High Bleeding Risk: A Patient-Level Stratified Analysis from Four Post-Approval Studies.
Conclusions: Compared to the non-HBR population, HBR patients experienced worse 4-year outcomes after PCI with CoCr everolimus-eluting stent. Both CTE and MB had a significant impact on subsequent risk of mortality irrespective of bleeding risk. PMID: 31992063 [PubMed - as supplied by publisher]
