Proteomic insights into the invasiveness and tumor progression of non‐functioning pituitary adenomas: A scoping review

Journal of Neuroendocrinology, Volume 38, Issue 3, March 2026.
Abstract Nonfunctioning pituitary adenomas (NFPAs) are common intracranial tumors that, despite being histologically benign, can exhibit invasive growth, as well as postoperative tumor progression. Surgical resection is the primary treatment of choice; however, residual tumor tissue is frequently observed, with between 30% and 50% of these cases ...

Preoperative Metabolic Predictors of Granulation Subtypes in Somatotroph Tumors: A Multicenter Retrospective Cohort Study

CNS Neuroscience &Therapeutics, Volume 32, Issue 2, February 2026.
Somatotroph tumors, a rare subtype of pituitary adenomas, can be histologically classified into sparsely granulated (SGSTs) and densely granulated somatotroph tumors (DGSTs) based on cytokeratin staining. SGSTs are generally more invasive and less responsive to medical therapy, making their early identification clinically important.

Should positive airway pressure be continued uninterrupted after endoscopic skull base surgery? A review of current literature

Journal of Sleep Research, Volume 35, Issue 1, February 2026.
Summary Obstructive sleep apnea (OSA) poses unique challenges to the perioperative management of endoscopic skull base surgery (ESBS). Currently, no consensus or guidelines exist on the reintroduction of positive airway pressure (PAP) in these patients.
