Primary central nervous system (CNS) lymphoma (PCNSL) is an uncommon extranodal non-Hodgkin lymphoma often presenting as a single brain lesion within the CNS. On histopathological evaluation of PCNSL a positive CD10, which is frequently observed in systemic diffuse large B-cell lymphoma, is present in approximately 10% of PCNSL. We describe a case of CD10-positive PCNSL presenting with multiple posterior fossa enhancing lesions in an immunocompetent older woman with a history of breast cancer successfully treated by the RTOG 0227 protocol consisting of pre-irradiation chemotherapy with high-dose methotrexate, rituximab, and temozolomide for 6 cycles, followed by low-dose whole-brain radiation and post-irradiation temozolomide.

Screening high-risk Veterans for cirrhosis: taking a stepwise population health approach.
BMC Health Serv Res
January 2025
VA Center for Health Equity Research and Promotion, Pittsburgh, PA, USA.
Background: Because cirrhosis is often unrecognized, we aimed to develop a stepwise screening algorithm for cirrhosis in the Veterans Health Administration (VHA) and assess this approach's feasibility and acceptability.
Methods: VHA hepatology clinicians ("champions") were invited to participate in a pilot program from June 2020 to October 2022. The VHA Corporate Data Warehouse was queried to identify Veterans with possible undiagnosed cirrhosis using Fibrosis-4 (FIB-4) ≥ 3.
NLRX1 limits inflammatory neurodegeneration in the anterior visual pathway.
J Neuroinflammation
January 2025
Department of Neurology, Division of Neuroimmunology, School of Medicine, Johns Hopkins University, Baltimore, MD, 21287, USA.
Chronic innate immune activation in the central nervous system (CNS) significantly contributes to neurodegeneration in progressive multiple sclerosis (MS). Using multiple experimental autoimmune encephalomyelitis (EAE) models, we discovered that NLRX1 protects neurons in the anterior visual pathway from inflammatory neurodegeneration. We quantified retinal ganglion cell (RGC) density and optic nerve axonal degeneration, gliosis, and T-cell infiltration in Nlrx1 and wild-type (WT) EAE mice and found increased RGC loss and axonal injury in Nlrx1 mice compared to WT mice in both active immunization EAE and spontaneous opticospinal encephalomyelitis (OSE) models.

Department of Neurology, Dongzhimen Hospital, Beijing University of Chinese Medicine, Beijing, China.
Background: Suhexiang (SHX) pill is widely used for treating acute ischemic stroke (AIS). Experimental and randomized controlled trials suggested that SHX pill was beneficial for patients with AIS. However, the effectiveness of SHX pill in real-world practice setting remains unclear.

January 2025
Neurological Disorder Center, Department of Cerebrovascular Disease, Suining Central Hospital, Sichuan, 629000, China.
Background: Hyponatremia (< 135 mmol/L) is the most common electrolyte disturbance in patients with stroke. However, few studies have reported the relationship between hyponatremia at admission and outcomes in patients with acute ischemic stroke (AIS) treated with mechanical thrombectomy (MT). This study is aimed to explore the association between hyponatremia and clinical outcomes following MT.

BMC Cardiovasc Disord
January 2025
Department of Cardiac Rehabilitation, Zhengzhou Central Hospital Affiliated to Zhengzhou University, Zhengzhou, 450000, China.
Background: Tai Chi is a low-impact form of exercise that involves a series of slow movements that flow together. Increased plasma homocysteine(Hcy) levels are associated with an increased risk of cardiovascular diseases and may be reduced by exercise. This study aimed to compare plasma Hcy levels and the risk of hyperhomocysteinemia in 1,176 adults with and without Tai Chi exercises.
