AIM2 inflammasome contributes to brain injury and chronic post-stroke cognitive impairment in mice.
Abstract Although over one-third of stroke patients may develop post-stroke cognitive impairment (PSCI), the mechanisms underlying PSCI remain unclear. We explored here, the involvement of post-stroke inflammasomes in long-term PSCI development, using a 45 min-middle cerebral artery occlusion (MCAO)/reperfusion-induced PSCI model. Immunohistological assessment on day 1, 3, and 7 was followed by cognitive function test 28 days post-stroke. Evaluation of inflammasome sensor gene expression in aged mouse brains showed dominant expression of absent in melanoma 2 (Aim2) in 6-, 12-, and 18-month-old mouse brains. AIM2 m...

Long non-coding RNA MEG3 promotes cerebral ischemia-reperfusion injury through increasing pyroptosis by targeting miR-485/AIM2 axis.
CONCLUSION: MEG3/miR-485/AIM2 axis contributes to pyroptosis via activating caspase1 signaling during cerebral I/R, suggesting that this axis may be a potent therapeutic target in ischemic stroke. PMID: 31794744 [PubMed - as supplied by publisher]

Intraoperative Aneurysm Rupture during Resection for Presumed Metastasis
A 54-year-old male with metastatic melanoma, including a presumed brain metastasis underwent elective surgery when there was sudden onset of extensive bleeding upon resection. An emergent cerebral angiogram revealed a fusiform left posterior cerebral artery aneurysm. Malignant melanoma commonly metastasizes to the brain and has shown to assume a wide variety of appearances with involvement of almost any intracranial structures. The unexpected intraoperative finding required immediate action and strategic rethinking.

C-Reactive Protein and Risk of Parkinson's Disease: A Systematic Review and Meta-Analysis
Conclusions: This meta-analysis revealed that PD is associated with an increase of CRP levels. CRP might be a risk factor for PD or PD leads to an inflammatory response. Introduction Parkinson's disease (PD) is one of the most complex neuro-degenerative disorders next to Alzheimer's disease. It is characterized by bradykinesia, tremor, rigidity, abnormal postural, and gait (1). PD has been recognized by the selective loss of dopaminergic neurons within the substantia nigra pars compacta, whereas the exact etiology remains elusive (2). Previously, multiple inferences have reviewed the environmental a...

Risk of Ischemic and Hemorrhagic Strokes in Occult and Manifest Cancers Clinical Sciences
Conclusions—Cancer, occult and manifest, is associated with increased risks for stroke. The increased risk is linked mainly to cancers related to smoking.

Neurologic manifestations of geriatric patients with cancer (P6.188)
Conclusions:Neurologic manifestations are reported in about 40% of patients with cancer, approximately half of living patients with cancer are over 65 years of age, this increase merits the medical and related personnel to be prepared and recognize, diagnose and treat this highly morbid conditions. Neurologic manifestations and diagnoses in patients with cancer are different in the elderly and should be treated individually; the present work offers information regarding clinical symptoms and neurologic diagnoses in this population.Disclosure: Dr. Cacho Diaz has nothing to disclose. Dr. Lorenzana-Mendoza has nothing to disc...

Cytosolic Receptor Melanoma Differentiation-Associated Protein 5 Mediates Preconditioning-Induced Neuroprotection Against Cerebral Ischemic Injury Brief Reports
Conclusions— Poly-ICLC preconditioning is mediated by melanoma differentiation–associated protein 5 and its adaptor molecule IFN-promoter stimulator 1. This is the first evidence that a cytosolic receptor can mediate neuroprotection, providing a new target for the development of therapeutic agents to protect the brain from ischemic injury.

Mortality and comorbidities in patients with multiple sclerosis compared with a population without multiple sclerosis: An observational study using the US department of defense administrative claims database
Conclusions Rates of mortality and several comorbidities are higher in the MS versus non-MS cohort. Early recognition and management of comorbidities may reduce premature mortality and improve quality of life in patients with MS.

Clinical Outcomes of Metastatic Intra-cerebral Hemorrhage and Role of Acute Radiotherapy (P3.077)
CONCLUSIONS: Early recognition of metastatic disease as the etiology of ICH is important, particularly when it is the presenting manifestation. Despite the overall poor prognosis of metastatic cancer, early radiotherapy may increase survival and offer quality of life in selected group of patients. A larger case series is needed.Disclosure: Dr. Afzal has nothing to disclose. Dr. Mendoza has nothing to disclose. Dr. Latorre has nothing to disclose.
