Validation of on‐slide immunocytochemistry controls prepared from long‐term preserved prefixed cell suspensions

open access: yesCancer Cytopathology, Volume 134, Issue 2, February 2026.
Abstract Background On‐slide controls are essential for quality assurance in immunocytochemistry, yet their use in non–cell block cytology preparations remains a significant challenge. This study presents and evaluates a novel method for preparing on‐slide controls from long‐term prefixed cell suspensions, applicable to all types of cytology ...

A Cell‐Intrinsic Role for RANK in Regulatory T Cells of the Human Thymus

open access: yesEuropean Journal of Immunology, Volume 56, Issue 2, February 2026.
We identified RANK (TNFRSF11a) expression in human thymic FOXP3+ Tregs, revealing a previously unknown role for the RANK‐RANKL axis in human tTreg development. We show that IL‐2 and IL‐15 can drive RANK expression in CD4+ tTregs, which in turn may modulate their maturation and proliferation within the thymic environment. Created in BioRender. Biorender,

Development and Validation of the Brief Inventory of Treatment Expectations in Chronic Pain (BITEC)

open access: yesEuropean Journal of Pain, Volume 30, Issue 2, February 2026.
ABSTRACT Background Expectations shape therapeutic outcomes, yet their systematic assessment remains limited in clinical and research settings. To address this gap, we developed and validated the Brief Instrument for the Assessment of Treatment Expectations in Chronic Pain (BITEC) using Item Response Theory. Methods The study comprised four phases. (I)

Using artificial intelligence as a technological tool in gynecologic and obstetric health: A narrative literature review

open access: yesInternational Journal of Gynecology &Obstetrics, Volume 172, Issue 2, Page 850-865, February 2026.
Abstract Maternal mortality remains a critical global public health issue, particularly in low‐ and middle‐income settings where failures in surveillance, early diagnosis, and clinical decision making compromise obstetric care. In this context, the present study aimed to critically review the scientific literature on the use of artificial intelligence (
