Background: Pancreatoblastoma is an extremely rare neoplasm that accounts for 0.5% of all pancreatic exocrine tumors. These rare entities typically manifest in the pediatric population but can rarely occur in adults. Systemic seeding has been described before but intracranial metastasis in adults has yet to be described.
Case Description: A 28-year-old woman with a history of pancreatoblastoma that had been in remission for 51 months after treatment with cisplatin, doxorubicin (Adriamycin), and etoposide had presented to the emergency room with chronic recurrent headaches. Conservative management of the headaches failed, which led to a diagnostic workup with magnetic resonance imaging of the brain. Magnetic resonance imaging demonstrated a well-circumscribed solitary cerebellar lesion. Metastatic disease was suspected, and the patient underwent suboccipital craniotomy for tumor resection with adjuvant gamma knife radiosurgery.
Conclusions: Central nervous system seeding of pancreatoblastoma is rare, and the available evidence suggests that the strategy we used could be adequate for treating such occurrences.

Randomized Comparison of Magnetic Resonance Imaging Versus Transurethral Resection for Staging New Bladder Cancers: Results From the Prospective BladderPath Trial.
J Clin Oncol

Institute of Cancer Research, London, United Kingdom.
Purpose: Transurethral resection of bladder tumor (TURBT) is the initial staging procedure for new bladder cancers (BCs). For muscle-invasive bladder cancers (MIBCs), TURBT may delay definitive treatment. We investigated whether definitive treatment can be expedited for MIBC using flexible cystoscopic biopsy and multiparametric magnetic resonance imaging (mpMRI) for initial staging.

Purpose: Perfusion modeling presents significant opportunities for imaging biomarker development in breast cancer but has historically been held back by the need for data beyond the clinical standard of care (SoC) and uncertainty in the interpretability of results. We aimed to design a perfusion model applicable to breast cancer SoC dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) series with results stable to low temporal resolution imaging, comparable with published results using full-resolution DCE-MRI, and correlative with orthogonal imaging modalities indicative of biophysical markers.
Methods: Subsampled high-temporal-resolution DCE-MRI series were run through our perfusion model and resulting fits were compared for consistency.
Specialization of the human hippocampal long axis revisited.
Proc Natl Acad Sci U S A

Department of Psychology, Center for Brain Science, Harvard University, Cambridge, MA 02138.
The hippocampus possesses anatomical differences along its long axis. Here, we explored the functional specialization of the human hippocampal long axis using network-anchored precision functional MRI in two independent datasets (N = 11 and N = 9) paired with behavioral analysis (N = 266 and N = 238). Functional connectivity analyses demonstrated that the anterior hippocampus was preferentially correlated with a cerebral network associated with remembering, while the posterior hippocampus selectively contained a region correlated with a distinct network associated with behavioral salience.

Background: Optic neuritis (ON) is a complex clinical syndrome that has diverse etiologies and treatments based on its subtypes. Notably, ON associated with multiple sclerosis (MS ON) has a good prognosis for recovery irrespective of treatment, whereas ON associated with other conditions including neuromyelitis optica spectrum disorders or myelin oligodendrocyte glycoprotein antibody-associated disease is often associated with less favorable outcomes. Delay in treatment of these non-MS ON subtypes can lead to irreversible vision loss.

This study employs a low-field NMR (LF-NMR) method to investigate Cr(VI) adsorption and reduction in solid-liquid systems, focusing on three cellulose-based amine adsorbents. NMR revealed the effects of molecular structure on adsorption and reduction processes, providing insights into adsorbent design and mass transfer advantages for high-performance Cr(VI) adsorbents.
