Toxicity in the era of immune checkpoint inhibitor therapy.

Immune checkpoint inhibitors (ICIs) reinvigorate anti-tumor immune responses by disrupting co-inhibitory immune checkpoint molecules such as programmed cell death 1 (PD-1) and cytotoxic T lymphocyte antigen 4 (CTLA-4). Although ICIs have had unprecedented success and have become the standard of care for many cancers, they are often accompanied by off-target inflammation that can occur in any organ system. These immune related adverse events (irAEs) often require steroid use and/or cessation of ICI therapy, which can both lead to cancer progression.

Accelerated tumor progression after COVID-19 infection in patients with glioblastoma: A retrospective case-control study.

Background: We observed rapid tumor progression following COVID-19 infection among patients with glioblastoma and sought to systematically characterize their disease course in a retrospective case-control study.

Methods: Using an institutional database, we retrospectively identified a series of COVID-19-positive glioblastoma cases and matched them by age and sex 1:2 to glioblastoma controls who had a negative COVID-19 test during their disease course. Demographic and clinical data were analyzed.

Neurologic Complications of Cancer Immunotherapy.

Immunotherapy has revolutionized cancer treatment over the past decade. As it is increasingly introduced into routine clinical practice, immune-related complications have become more frequent. Accurate diagnosis and treatment are essential, with the goal of reduced patient morbidity.

Emerging Subspecialties in Neurology: Becoming an Editor-In-Chief.

An Editor-in-Chief leads the editorial team and supervises the daily tasks required to prepare articles for publication while managing the overall content and style of the journal. To become Editor-in-Chief, one must have dedicated work ethic, close attention to detail, passion for the editorial process, and a keen ability to work with and give feedback to section editors and authors. For this article, we interviewed Dr.

Associations between cerebrovascular risk factors and parkinson disease.

Objective: To determine whether cerebrovascular risk factors are associated with subsequent diagnoses of Parkinson disease, and whether these associations are similar in magnitude to those with subsequent diagnoses of Alzheimer disease.

Methods: This was a retrospective cohort study using claims data from a 5% random sample of Medicare beneficiaries from 2008 to 2015. The exposures were stroke, atrial fibrillation, coronary disease, hyperlipidemia, hypertension, sleep apnea, diabetes mellitus, heart failure, peripheral vascular disease, chronic kidney disease, chronic obstructive pulmonary disease, valvular heart disease, tobacco use, and alcohol abuse.

Central Nervous System Involvement of Natural Killer and T Cell Neoplasms.

Purpose Of Review: Peripheral natural killer (NK) and T cell neoplasms comprise approximately 10-15% of non-Hodgkin lymphomas. There are 27 different subtypes of peripheral NK and T cell neoplasms, each of which is relatively uncommon. Treatment has been largely extrapolated from case series, retrospective reports, and paradigms developed for the aggressive B cell lymphomas.
