Brain cancer is a group of diverse and rapidly growing malignancies that originate in the central nervous system (CNS) and have a poor prognosis. The complexity of brain structure and function makes brain cancer modeling extremely difficult, limiting pathological studies and therapeutic developments. Advancements in human pluripotent stem cell technology have opened a window of opportunity for brain cancer modeling, providing a wealth of customizable methods to simulate the disease in vitro. This is achieved with the advent of genome editing and genetic engineering technologies that can simulate germline and somatic mutations found in human brain tumors. This review investigates induced pluripotent stem cell (iPSC)-based approaches to model human brain cancer. The applications of iPSCs as renewable sources of individual brain cell types, brain organoids, blood-brain barrier (BBB), and brain tumor models are discussed. The brain tumor models reviewed are glioblastoma and medulloblastoma. The iPSC-derived isogenic cells and three-dimensional (3D) brain cancer organoids combined with patient-derived xenografts will enhance future compound screening and drug development for these deadly human brain cancers.

A 71-year-old black male with a history of hypertension, dyslipidemia, type 2 diabetes, history of bladder cancer status-post resection now in remission, history of multiple transient ischemic attacks, and coronary artery disease (CAD) presented with non-exertional substernal chest pain radiating to the left arm, accompanied by shortness of breath and nausea. Initial evaluation revealed elevated troponins and nonspecific electrocardiogram changes, consistent with non-ST elevation myocardial infarction. Coronary angiography demonstrated severe multivessel disease, including critical left main stenosis.

Purpose: Postoperative delirium (POD) remains poorly understood in terms of predictors and underlying mechanisms. This review summarized emerging evidence on the association between brain microstructural alterations and POD.
Method: This is a narrative review, describing the microstructural changes in aging brain, microstructural MRI findings, relationship among microstructural alterations, cognitive reserve and POD, and potential interventions targeting microstructure.

Purpose: Limited data is available assessing sequencing of antibody drug conjugates (ADCs) in patients with hormone receptor-positive (HR +), human epidermal growth factor 2 (HER2)-negative, HER2-low, and triple-negative metastatic breast cancer (MBC), including patients with brain metastases (BrM) or leptomeningeal disease (LMD). This study assesses the efficacy and safety of sequential sacituzumab govitecan (SG) and trastuzumab deruxtecan (T-DXd) in MBC and impact on chemotherapy (CTX).
Methods: This is a single-center, retrospective, cohort study in adult patients with HR + , HER2-negative, or low MBC who received T-DXd and/or SG.

Introduction: This study explores high-impedance surface (HIS) metamaterial shields for enhancing the transmit field in whole-body MRI at 7 T. We studied the possibility of placing a metamaterial layer between the gradient coil and bore liner using electromagnetic simulations to evaluate B and SAR efficiency across different impedances.
Materials And Methods: Simulations were performed in three stages, first metamaterial design and characterization, then single-element dipole simulations with a homogenous phantom, and finally, simulations including a four-element arrays with a virtual body model, including the whole scanner geometry.

Purpose: Patients diagnosed with high-grade gliomas (HGG) often experience substantial psychosocial dis-tress. However, due to neurological and neurocognitive deficits its assessment remains challenging, and needs remain unmet. We compared a novel face-to-face assessment during doctor-patient conversations with questionnaire-based screening.
