Glioblastoma-associated immunosuppression is a significant factor associated with poor survival in this disease. Accumulating evidence suggests that mouse models of glioblastoma and other brain cancers induce systemic immunosuppression through dysregulation of a newly recognized brain-thymus axis and that targeting this pathway may promote more effective immune surveillance of these tumors.
Serum phospho-tau217, a biomarker of tau protein that can be detected in the blood, is increased in preclinical Alzheimer’s disease and may have clinical utility for the early detection of brain pathology.
Hospitals nationwide have focused on handling overflow of COVID-19 patients needing acute care. They also are developing programs to handle post-acute medical problems discharged COVID-19 patients face.
In subjects with a syndrome associated with frontotemporal lobar degeneration, gamma aminobutyric acid and glutamate deficiency in the right inferior frontal gyrus was associated with greater degrees of impulsivity.
As often is the case in medical malpractice cases, defendants made a concerted effort to dismiss the case based on the insufficiency of the plaintiff’s expert report. Here, however, the court of appeals began its analysis by specifying that based on the applicable standard of review, the purpose of the plaintiffs’ expert report is to demonstrate the plaintiff is not filing a frivolous lawsuit.
Researchers evaluated the presence and pathological significance of extracranial systemic and cerebral small vessel disease in patients with multiple sclerosis (MS) compared to healthy controls. MS patients exhibited less systemic vascular disease and more small vessel disease in the brain vs. controls.
Appreciating the need for more guidance in this area, an international task force comprised of physician-scientists from 10 countries developed consensus-based guidelines to help frontline providers diagnose and triage patients with dizziness over a telehealth or virtual platform.
This postmortem study of multiple sclerosis (MS) patients evaluated the presence and pathological significance of extracranial systemic and cerebral small vessel disease in patients with MS compared to healthy controls. MS patients had less systemic vascular disease and more small vessel disease in the brain compared to controls.
Covert brain infarcts are detected on magnetic resonance imaging studies in the aging brain in about 10% of people at age 65 years, increasing to 25% at age 80 years. Most patients who develop dementia have a combination of multiple small infarcts, plus amyloid deposition. Prevention of covert infarcts is a strategy to mitigate the frequency and severity of late-life dementia.
In this randomized, placebo-controlled trial using tranexamic acid to treat patients with moderate or severe traumatic brain injury within two hours of injury, there was no significant difference between treatment groups in either mortality or functional recovery at six months.
