Mechanical ventilation is a known risk factor for delirium, cognitive impairment characterized by dysfunction of the frontal cortex and hippocampus. Although IL-6 upregulated in mechanical ventilation-induced lung injury (VILI) may contribute to it not whether inhibition systemic mitigates delirium-relevant neuropathology. To histologically define neuropathological effects an experimental VILI model, was simulated anesthetized adult mice using 35 cc/kg tidal volume model. There were two...

Abstract Objective Pharmacoresistance develops quickly during repetitive seizures, and refractory status epilepticus ( RSE ) remains a therapeutic challenge. The outcome of is poor, with high mortality morbidity. New treatments are needed. Deep hypothermia (20°C) used clinically reconstructive cardiac surgery neurosurgery, has proved safe effective in those indications. We tested the hypothesis that deep reduces its long‐term consequences. Methods model SE induced by lithium pilocarpine to...

Abstract Acute neuropsychiatric impairments occur in over 70% of patients with acute lung injury. Mechanical ventilation is a well-known precipitant injury and strongly associated the development delirium anxiety phenotypes. In prior studies, we demonstrated that IL-6 mediates neuropathological changes frontal cortex hippocampus animals mechanical ventilation-induced brain injury; however, effect systemic inhibition on structural functional phenotypes not known. We hypothesized murine model...

Nonhepatic hyperammonemia syndrome is a rare cause of neurologic dysfunction and cerebral edema has most commonly been reported in posttransplant patients. Only recently opportunistic infection with Ureaplasma species Mycoplasma hominis found to be key the pathogenesis. We describe cases 3 immunosuppressed patients who developed new-onset refractory status epilepticus diffuse edema. PCR was positive for M 1 patient parvum other 2. Despite early diagnostic suspicion aggressive management...

Intrathecal methotrexate (IT MTX) resulting in severe adverse events including life-threatening cerebral edema is not well described. We report a rare case of death 37-year-old BRCA1+ woman with metastatic triple-negative breast cancer status post mastectomy following administration IT MTX for leptomeningeal carcinomatosis. Within the 24 hours after intraoperative delivery, she developed neurologically devastating diffuse leading to uncal and cerebellar tonsillar herniation. This highlights...

Urinary tract infections (UTIs) are common and frequently precipitate delirium-like states. Advanced age coincident with the postmenopausal period is a risk factor for delirium following UTIs. We previously demonstrated pathological role interleukin-6 (IL-6) in mediating phenotypes murine model of UTI. Estrogen has been implicated reducing peripheral IL-6 expression, but it unknown whether increased susceptibility females to developing concomitant UTIs reflects diminished effects circulating...

However, there is little existing data community. Prior research has shown cis-gender men with initially low levels increases stroke, especially first 2...

Abstract Background: Prior published data show that short-term mechanical ventilation contributes to pathological hallmarks of Alzheimer’s Disease (AD) by increasing cerebral accumulation the amyloid-β 1-40 (Aβ ) peptide and neuroinflammation while unexpectedly decreasing blood-brain barrier permeability. In this study, we hypothesized acute immunochallenge promotes physiological emergence Aβ regions vascular disruption, resulting in reduced neuronal injury. Methods: Immunohistology was used...
