Perlecan Domain-V Enhances Neurogenic Brain Repair After Stroke in Mice.

The extracellular matrix fragment perlecan domain V is neuroprotective and functionally restorative following experimental stroke. As neurogenesis is an important component of chronic post-stroke repair, and previous studies have implicated perlecan in developmental neurogenesis, we hypothesized that domain V could have a broad therapeutic window by enhancing neurogenesis after stroke. We demonstrated that domain V is chronically increased in the brains of human stroke patients, suggesting that it is present during post-stroke neurogenic periods.

Successful Extracorporeal Membrane Oxygenation (ECMO) Use without Systemic Anticoagulation for Acute Respiratory Distress Syndrome in a Patient with Aneurysmal Subarachnoid Hemorrhage.

Extracorporeal membrane oxygenation (ECMO) is an important life-saving technology for patients with severe acute respiratory distress syndrome (ARDS). Unfortunately, ECMO has been traditionally contraindicated in patients with hemorrhagic neurologic diseases. The recent improvement in ECMO devices, increased utilization and experience with venovenous ECMO technologies among healthcare teams, and the use of ECMO without anticoagulation has expanded the potential populations that may benefit from ECMO.

Novel Temporary Treatment for a Severe Case of Syndrome of Trephined.

Background: Syndrome of the trephined is a unique neurosurgical condition that is seen in patients that have undergone craniectomy. While the symptoms of the condition range from mild to severe, the only definitive treatment for the condition is replacement of the bone flap. This article presents a novel, temporary treatment for syndrome of the trephined in a patient with severe symptoms who was unable to undergo immediate cranioplasty due to infection.

The Kentucky Appalachian Stroke Registry (KApSR).

Background: The population of rural Kentucky and West Virginia has a disproportionately high incidence of stroke and stroke risk factors. The Kentucky Appalachian Stroke Registry (KApSR) is a novel registry of stroke patients developed to collect demographic and clinical data in real time from these patients' electronic health records.

Objective: We describe the development of this novel registry and test it for ability to provide the information necessary to identify care gaps and direct clinical management.

Factors Associated with Moyamoya Syndrome in a Kentucky Regional Population.

Objectives: Our study aimed to report both new and previously identified conditions associated with moyamoya syndrome in a Western population and to present our outcomes after surgical treatment with indirect bypass.

Methods: We performed a retrospective chart review of patients evaluated at our institution from June 2011 to June 2015 who were diagnosed with moyamoya. Data collected include patient demographics, presenting manifestations, vessels involved, comorbid conditions, abnormal laboratory values, treatments administered, and clinical outcomes.

Urotensin II acts as a modulator of mesopontine cholinergic neurons.

Urotensin II (UII) is a vasomodulatory peptide that was not predicted to elicit CNS activity. However, because we have recently shown that the urotensin II receptor (UII-R) is selectively expressed in rat mesopontine cholinergic (MPCh) neurons, we hypothesize that UII may have a central function. The present study demonstrates that the UII system is able to modulate MPCh neuron activity.

Urotensin II modulates rapid eye movement sleep through activation of brainstem cholinergic neurons.

Urotensin II (UII) is a cyclic neuropeptide with strong vasoconstrictive activity in the peripheral vasculature. UII receptor mRNA is also expressed in the CNS, in particular in cholinergic neurons located in the mesopontine tegmental area, including the pedunculopontine tegmental (PPT) and lateral dorsal tegmental nuclei. This distribution suggests that the UII system is involved in functions regulated by acetylcholine, such as the sleep-wake cycle.
