Neutrophils restricted contribution of genetic variants to COVID-19 severity.

The 3p21.31 locus is the most robust genomic region associated with COVID-19 severity. This locus contains a main chemokine receptor (CKR) cluster.

Exploring oncology treatment strategies with tyrosine kinase inhibitors through advanced 3D models (Review).

The limitations of two-dimensional (2D) models in cancer research have hindered progress in fully understanding the complexities of drug resistance and therapeutic failures. However, three-dimensional (3D) models provide a more accurate representation of environments, capturing critical cellular interactions and dynamics that are essential in evaluating the efficacy and toxicity of tyrosine kinase inhibitors (TKIs). These advanced models enable researchers to explore drug resistance mechanisms with greater precision, optimizing treatment strategies and improving the predictive accuracy of clinical outcomes.

The Role of Scanning Electron Microscopy in the Evaluation of Conjunctival Microvilli as an Early Biomarker of Ocular Surface Health: A Literature Review.

Microvilli are bristle-like protuberances of the plasma membrane, which express the vitality of mucous and epithelial cells; their alteration indicates a condition of cellular suffering in a predictive sense, making it possible to establish how much an inflammatory state or toxic conditions affect cellular functionality. In this article, the authors evaluate the applications of scanning electron microscopy (SEM) examination to impression cytology (IC) of the bulbar conjunctiva for the assessment of microvillar alteration as an early ultrastructural indicator of ocular surface health. This method offers several advantages, starting with its simplicity: it involves the non-invasive application of a strip of bibulous paper to the bulbar or tarsal conjunctiva.

Microenvironmental Traits of Classical Hodgkin's Lymphoma in Adolescents and Their Prognostic Impact.

Background: Classical Hodgkin's lymphoma (cHL) in adolescents between 15 and 18 years old shows a higher disease-related mortality, and the overall prognosis is worse than in both children and adults.

Objectives: We investigated the immune checkpoint inhibitors (ICPIs) therapeutic targets and specific T-regulatory and cytotoxic T-cell subsets in the subgroup of adolescent cHL patients, and we challenged their prognostic power.

Methods: We retrieved formalin-fixed paraffin-embedded (FFPE) tissue of adolescent patients diagnosed with cHL and tested by immunohistochemistry the immune checkpoint molecules CTLA-4, LAG-3, PD-1, and PDL1 as well as the biological markers FOXP3 and CD8.

Experience of Safety and Health Promotion in Dolomites Area.

The mountain context represents a suitable setting for promoting health. In view of the Olympic Games, which are expected to take place in the Dolomites area in 2026, the outdoor Alpine environment must continue to meet all the health and safety requirements. Our recent experience, implemented in this area since summer 2024 through the Prevention Department of the Local Health Authority ULSS 1 Dolomiti, aims to encourage multi-sector preventive public health policies, in order to improve the "Shelters" ("rifugi", in Italian) hygiene, to strengthen the safety requirements, and to implement preventive projects.
