Real-World Evaluation of Dupilumab in the Long-Term Management of Eosinophilic Chronic Rhinosinusitis with Nasal Polyps: A Focus on IL-4 and IL-13 Receptor Blockade.

: Chronic rhinosinusitis (CRS) is a complex inflammatory condition of the nasal passages that severely impairs quality of life. Type 2 CRS is characterized by eosinophilic inflammation, driven by cytokines like IL-4, IL-5, and IL-13. These cytokines are key to CRS pathogenesis and contribute to a heavy disease burden, especially with comorbidities.

Factors Affecting the Density of Corneal Endothelial Cells Cultured from Donor Corneas.

We investigated which specific correlation exists between the endothelial cell density (ECD) of corneal endothelial cell (CEC) cultures and the features of the donor corneas from which they originate. CEC cultures were prepared from one donor cornea or by pooling together cells of more corneas from elderly donors with ECDs lower or higher than 2000 cells/mm. The ECDs of such primary cultures were evaluated and showed that that ECDs > 2000 cells/mm can be obtained only when CECs are isolated from (1) corneas of young donors; (2) at least two elderly donor corneas (if ECD > 2000 cells/mm), or three elderly donor corneas (if ECD < 2000 cells/mm).

Selective metabolic regulations by p53 mutant variants in pancreatic cancer.

Background: Approximately half of all human cancers harbour mutations in the p53 gene, leading to the generation of neomorphic p53 mutant proteins. These mutants can exert gain-of-function (GOF) effects, potentially promoting tumour progression. However, the clinical significance of p53 GOF mutations, as well as the selectivity of individual variants, remains controversial and unclear.

Evolocumab treatment reduces carotid intima-media thickness in paediatric patients with heterozygous familial hypercholesterolaemia.

Aim: Children with heterozygous familial hypercholesterolaemia (HeFH) show greater carotid intima-media thickness (cIMT). Evolocumab, a proprotein convertase subtilisin/kexin type 9 inhibitor monoclonal antibody, substantially reduced low-density lipoprotein cholesterol (LDL-C) and modestly reduced lipoprotein(a) in children with HeFH. We investigated evolocumab's effect on cIMT progression.

Comparison of rebubbling rate between preloaded endothelium-in and preloaded no-touch endothelium-out Descemet membrane endothelial keratoplasty transplantation.

Background: To compare the difference in rebubbling rates between patients undergoing Descemet membrane endothelial keratoplasty (DMEK) with endothelium-in using a standard IOL cartridge and those with endothelium-out DMEK utilizing a no-touch technique with borosilicate glass cartridge transplantation.

Methods: This retrospective study included all eyes that underwent preloaded endothelium-in or endothelium-out DMEK transplantation from June 2019 to December 2023 at the Hanusch Hospital, Vienna, Austria. All DMEKs were harvested, prepared and preloaded at the European Eye Bank of Venice, Italy.
