Pituitary adenomas: biology, nomenclature and clinical classification.

Rev Endocr Metab Disord

January 2025

Pituitary Center, Cedars-Sinai Medical Center, Los Angeles, CA, USA.

An 'adenoma' is a benign neoplasm composed of epithelial tissue, and has been standard nomenclature for primary pituitary neoplasms. In 2022, the fifth edition of the WHO Classification of Endocrine Tumours and of Central Nervous System Tumours, renamed pituitary adenomas as neuroendocrine tumours (NETs), assigning an oncology label to pituitary invariably benign neoplasms. Multidisciplinary workshops convened by the Pituitary Society have questioned the process, validity, and merit of this arbitrary change, while addressing the adverse clinical implications of the proposed new nomenclature.

Background: Non-Hodgkin lymphoma (NHL) is the seventh most common cancer among Asian, Native Hawaiian and Pacific Islanders (ANHPIs), yet the risk of death in specific ANHPI subgroups in the US is unknown.

Methods: We used Surveillance, Epidemiology, and End Results data to investigate relative survival and the risk of death among NHL patients in ANHPI subgroups. Cox proportional hazards models were used to estimate hazard ratios and 95% confidence intervals (CI), comparing ANHPI subgroups to non-Hispanic White (NHW) NHL patients for all-cause death and NHL-specific death.

Beyond the more common TFE3 fusion partners PRCC, ASPSCR1, and SFPQ, additional less common fusion partners of TFE3-rearranged renal cell carcinoma (RCC) have been described. Herein, we present an example of TFE3-rearranged renal cell carcinoma harboring fusion partner MAPK1IP1L, a rare rearrangement with only one other reported tumor found in the literature. The currently reported TFE3-rearranged RCC demonstrates unique histological features compared to the previously reported tumor including dense eosinophilic cytoplasm and nuclear pseudoinclusions (corroborated by electron microscopic evaluation), with features not typically seen in other TFE3-rearranged RCCs.

Pericytes mediate neuroinflammation via Fli-1 in endotoxemia and sepsis in mice.

Inflamm Res

January 2025

Department of Pathology and Laboratory Medicine, Medical University of South Carolina, 173 Ashley Ave, Charleston, SC, 29425, USA.

Background: Sepsis-associated encephalopathy (SAE) often results from neuroinflammation. Recent studies have shown that brain platelet-derived growth factor receptor β (PDGFRβ) cells, including pericytes, may act as early sensors of infection by secreting monocyte chemoattractant protein-1 (MCP-1), which transmits inflammatory signals to the central nervous system. The erythroblast transformation-specific (ETS) transcription factor Friend leukemia virus integration 1 (Fli-1) plays a critical role in inflammation by regulating the expression of key cytokines, including MCP-1.

The nucleus tractus solitarius (NTS) contains neurons that relay sensory swallowing commands information from the oropharyngeal cavity and swallowing premotor neurons of the dorsal swallowing group (DSG). However, the spatio-temporal dynamics of the interplay between the sensory relay and the DSG is not well understood. Here, we employed fluorescence imaging after microinjection of the calcium indicator into the NTS in an arterially perfused brainstem preparation of rat (n = 8) to investigate neuronal population activity in the NTS in response to superior laryngeal nerve (SLN) stimulation.

Human Metapneumovirus (HMPV) is a re-emerging respiratory pathogen causing significant morbidity and mortality, particularly among young children, the elderly, and immunocompromised individuals. First identified in 2001, HMPV has since been recognised as a leading cause of acute respiratory tract infections (ARTIs) worldwide. Its transmission occurs through droplets, direct contact, and surface contamination, with crowded spaces and healthcare facilities serving as key environmental amplifiers.

Myocardial infarction can lead to the loss of billions of cardiomyocytes, and while cell-based therapies are an option, immature nature of in vitro-generated human induced pluripotent stem cell (iPSC)-derived cardiomyocytes (iCMs) is a roadblock to their development. Existing iPSC differentiation protocols don't go beyond producing fetal iCMs. Recently, adult extracellular matrix (ECM) was shown to retain tissue memory and have some success driving tissue-specific differentiation in unspecified cells in various organ systems.

Toluene-2,5-Diamine Sulfate: Allergen of the Year 2025.

Dermatitis

January 2025

Department of Dermatology, University of California, San Francisco, California, USA.

Toluene-2,5-diamine sulfate (PTDS), also known as toluene diamine sulfate or 2,5-diaminotoluene sulfate, is an aromatic amine that can be used as a paraphenylenediamine (PPD) hair dye alternative. Patients may develop contact allergy to PTDS, and it is often omitted from standard patch test screening series, possibly leading to underdiagnosis. The American Contact Dermatitis Society named PTDS the Allergen of the Year for 2025, aiming to raise awareness of its dual role as both an allergen and an alternative for some PPD-allergic individuals.
