Intravenous thrombolysis in a stroke patient with a repaired aortic dissection.

Acute aortic dissection is considered a contraindication to the use of intravenous thrombolysis in patients presenting with acute ischaemic stroke, but less has been described about previously repaired dissections. We present a case of a woman in her 50s presenting with acute left hemiparesis with a known history of aortic dissection within the thrombolysis window. After multidisciplinary discussion with cardiothoracic surgery and discussion with the patient, she was treated with intravenous thrombolysis without complication.

The Piezo channel is a mechano-sensitive complex component in the mammalian inner ear hair cell.

The inner ear is the hub where hair cells (HCs) transduce sound, gravity, and head acceleration stimuli to the brain. Hearing and balance rely on mechanosensation, the fastest sensory signals transmitted to the brain. The mechanoelectrical transducer (MET) channel is the entryway for the sound-balance-brain interface, but the channel-complex composition is not entirely known.

The Piezo channel is central to the mechano-sensitive channel complex in the mammalian inner ear.

The inner ear is the hub where hair cells transduce sound, gravity, and head acceleration stimuli carried by neural codes to the brain. Of all the senses, hearing and balance, which rely on mechanosensation, are the fastest sensory signals transmitted to the central nervous system. The mechanoelectrical transducer (MET) channel in hair cells is the entryway for the sound-balance-brain interface, but the channel's composition has eluded biologists due to its complexity.

Intra-arterial Thrombolysis for Acute Retinal Ischemia: A Retrospective, Observational, Cohort Study.

Background: To determine whether intra-arterial thrombolysis (IAT) within 16 hours after the onset of symptoms is feasible and associated with better visual outcomes in patients with acute retinal ischemia (ARI).

Methods: The retrospective cohort study was performed from January 2014 to December 2021 in the Xuanwu Hospital of Capital Medical University. Patients with ARI who initially presented visual acuity of 20/100 or worse were screened in the study.

Detection of Atrial Fibrillation After Central Retinal Artery Occlusion.

Background: Central retinal artery occlusion (CRAO) causes sudden, irreversible blindness and is a form of acute ischemic stroke. In this study, we sought to determine the proportion of patients in whom atrial fibrillation (AF) is detected by extended cardiac monitoring after CRAO.

Methods: We performed a retrospective, observational cohort study using data from the Optum deidentified electronic health record of 30.

Characteristics of strokes associated with centrifugal flow left ventricular assist devices.

Stroke is a devastating complication of left ventricular assist device (LVAD) therapy. Understanding the characteristics, risk factors and outcomes of strokes associated with the centrifugal flow LVADs is important to devise better strategies for management and prevention. This is a retrospective cohort study at a single US academic medical center.

Targeting GSNOR for functional recovery in a middle-aged mouse model of stroke.

The nitric oxide (NO) metabolome and the NO metabolite-based neurovascular protective pathways are dysregulated after stroke. The major NO metabolite S-nitrosoglutahione (GSNO) is essential for S-nitrosylation-based signaling events and the inhibition of S-nitrosoglutahione (GSNO)-metabolizing enzyme GSNO reductase (GSNOR) provides protective effects following cardiac ischemia. However, the role of GSNOR and GSNOR inhibition-mediated increased GSNO/S-nitrosylation is not understood in neurovascular diseases such as stroke.

ACDD score: A simple tool for assessing risk of pneumonia after stroke.

Background: Pneumonia is a serious but a preventable stroke complication. Prediction scales for post-stroke pneumonia have been proposed with an intent to improve surveillance and prevention but they remain under-utilized in clinical practice. Most existing scales were developed using both ventilated and non-ventilated patients which may affect their accuracy.

Effect of Blood Pressure Lowering in Early Ischemic Stroke: Meta-Analysis.

Background And Purpose: Elevated blood pressure is common in acute stage of ischemic stroke and the strategy to manage this situation is not well established. We therefore conducted a meta-analysis of randomized controlled trials comparing active blood pressure lowering and control groups in early ischemic stroke.

Methods: Pubmed, EMBASE, and Clinicaltrials.

Microarray and synchronization of neuronal differentiation with pathway changes in the Kyoto Encyclopedia of Genes and Genomes (KEGG) databank in nerve growth factor-treated PC12 cells.

The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway database creates networks from interrelations between molecular biology and underlying chemical elements. This allows for analysis of biologic networks, genomic information, and higher-order functional information at a systems level. We performed microarray experiments and used the KEGG database, systems biology analysis, and annotation of pathway function to study nerve growth factor (NGF)-induced differentiation of PC12 cells.

Assessment of short- and long-term outcomes of patients hospitalized with intracerebral hemorrhage.

The aim of this study was to assess short- and long-term outcomes of patients hospitalized with intracerebral hemorrhage (ICH) in South Carolina. Patients with a primary diagnosis of ICH (ICD-9-CM code 431) discharged during 2002 were identified in the South Carolina hospital discharge database. Kaplan-Meier estimates of recurrent stroke, myocardial infarct, vascular death, all-cause death, and composite events were calculated at 1 month, 6 months, and 1, 2, 3, and 4 years.
