The relationship of sex and aortic diameter at the time of acute type A aortic dissection.

Objective: Evaluate sex differences in patients undergoing repair of acute type A aortic dissection (ATAAD).

Methods: Sex-stratified, single-center cohort study of patients undergoing ATAAD repair from 1997 to 2022. The primary outcome was aortic diameter at time of presentation with ATAAD.

Rhinorrhea Recurrence After Posterior Nasal Nerve Cryoablation: A Multicenter Cohort Study.

Background: Posterior nasal nerve (PNN) cryoablation improves chronic rhinitis (CR) symptoms in 70-80% of cases, including clear thin rhinorrhea (CTR). This study's purpose was to determine time to and degree of CTR recurrence following cryoablation.

Methods: A multicenter retrospective cohort study was conducted on patients who underwent PNN cryoablation to treat CR-related CTR refractory to ipratropium bromide nasal spray (IBNS).

Interleukin 8-CXCR2 mediated neutrophil extracellular trap (NET) formation in biliary atresia associated with NET-Induced stellate cell activation.

Background Aims: Biliary atresia (BA) entails an inflammatory sclerosing lesion of the biliary tree, with prominent fibrosis in infancy. Previous studies revealed neutrophil-activating IL-8 and neutrophil extracellular traps (NETs) positively correlated with bilirubin and risk of liver transplant. The aims of this study were to determine the mechanism of NET formation (NETosis) in BA and if NETs induce stellate cell activation.

Inborn errors of immunity reveal molecular requirements for generation and maintenance of human CD4 IL-9-expressing cells.

Background: CD4 T cells play essential roles in adaptive immunity. Distinct CD4 T-cell subsets-T1, T2, T17, T22, T follicular helper, and regulatory T cells-have been identified, and their contributions to host defense and immune regulation are increasingly well defined. IL-9-producing T9 cells were first described in 2008 and appear to play both protective and pathogenic roles in human immunity.
