Improving the clinical translation of animal-based neural stem/progenitor cell (NSPC) therapies to humans requires an understanding of intrinsic human and animal cell characteristics. We report a novel method to assess spinal cord NSPCs from a small (rodent) and large (porcine) animal model in comparison to human NSPCs. To extract live adult human, porcine, and rodent spinal cord tissue, we illustrate a strategy using an anterior or posterior approach that was simulated in a porcine model. The initial expansion of primary NSPCs is carried out using the neurosphere assay followed by a pharmacological treatment phase during which NSPCs derived from humans, porcines, and rodents are assessed in parallel using the same defined parameters. Using this model, NSPCs from all species demonstrated multi-lineage differentiation and self-renewal. Importantly, these methods provide conditions to enable the direct comparison of species-dependent cell behavior in response to specific exogenous signals.

A 35-year-old woman presented with a progressive 3-year history of personality changes and gait impairment. Neurologic examination revealed bilateral optic atrophy, spastic paraparesis, and impaired vibratory sensation in all limbs, and neuropsychological evaluation identified a frontotemporal cognitive impairment. In this article, we review the differential diagnosis for a young woman with chronic frontotemporal dysfunction, optic atrophy, and dorsolateral myelopathy in a stepwise multidisciplinary approach.

We investigated BCMA-directed CART in patients with relapsed or refractory multiple myeloma (RRMM) and CNS involvement. Ten patients who received either ide-cel (n=6) or cilta-cel (n=4) were included in this analysis. Patients had brain/cranial nerve and/or spinal cord involvement/leptomeningeal disease evident on either MRI (100%) and/or CSF (40%).

Objective: To assess the association of systolic and diastolic blood pressure (SBP and DBP) in recently menopausal women with white matter hyperintensity (WMH) volume later in life and determine whether short-term menopausal hormone therapy (mHT) modifies these associations.
Methods: Kronos Early Estrogen Prevention Study (KEEPS) was a multicenter, randomized, double-blinded, placebo-controlled 4-year mHT trial (oral conjugated equine estrogens or transdermal 17β-estradiol). KEEPS continuation was an observational follow-up of the participants 10 years after the end of mHT.

Introduction: Chronic pelvic pain (CPP) is a multifaceted condition that poses significant challenges in clinical management owing to its complex and varied pathophysiology, including neuropathic, somatic, visceral, and musculoskeletal components. Endometriosis is frequently associated with CPP, necessitating a comprehensive, multimodal treatment strategy. This approach typically includes physical and behavioral therapy, pharmacologic interventions, surgical management of endometriosis, and various pain-modulating procedures.

Background/objectives: Transverse myelitis (TM) is a rare, acute inflammatory disorder affecting the spinal cord, with severe potential consequences, particularly in pediatric patients. Therapeutic plasma exchange (TPE) has emerged as a possible intervention for children unresponsive to high-dose corticosteroids. This study explores the efficacy of early TPE in pediatric TM through a case report and scoping review aiming to clarify the therapeutic benefits of TPE when used in conjunction with corticosteroids in children.
