Performance of spondyloarthritis-specific health utilities based on ASAS Health Index: an ancillary analysis from ASAS-HI validation study.

Objectives: To compare the utility values of Spondyloarthritis (SpA)-specific ASAS Health Index (U-ASAS-HI) to generic utilities and to understand the contribution of health outcomes, personal- and country-level factors to the U-ASAS-HI.

Methods: Ancillary analysis of the ASAS-HI international validation study. SpA patients who completed the ASAS-HI, 5-level EuroQol-5D (EQ-5D-5L) and Short Form-36 (SF-36) questionnaires were selected, and utilities calculated.

The optimal annual case volume for acute type A aortic dissection surgery in relation to long-term outcomes.

Objectives: Previous analyses of the volume-outcome relationship have focused on short-term outcomes such as early mortality. The current study aims to update a novel statistical methodology, facilitating the evaluation of the relation between procedural volume and time-to-event outcomes such as long-term survival, using surgery for acute type A aortic dissection as an illustrative example.

Methods: This study employed an existing dataset of type A dissection outcomes, retrieved from literature.

The External Validation of a Multivariable Prediction Model for Recurrent Pelvic Organ Prolapse After Native Tissue Repair: A Prospective Cohort Study.

: A prediction model for anatomical cystocele recurrence after native tissue repair was developed and internally validated in 2016. This model estimates a patients' individual risk of recurrence and can be used for counseling. Before implementation in urogynecological clinical practice, external validation is needed.

Intra-patient comparison of microarchitecture of tumour negative lymph nodes from oesophageal cancer patients - Results from the MRC Oe02 trial.

Background: Regional lymph node (LN) status is a key prognostic factor in oesophageal cancer (OeC). Tumour-derived antigens can activate immune reactions in LNs, potentially reflecting the host's anti-tumour immune response. It remains unclear whether this response is homogeneous across all tumour negative LNs (LNneg) within individual OeC patients.

The Italian version of the Surgical Fear Questionnaire: validation of its measurement properties.

Background: Surgical fear is present in many patients awaiting surgery. However, a validated Italian version of the Surgical Fear Questionnaire (SFQ) was not available yet. Therefore, the aim of this study was to translate the SFQ into Italian and to test its reliability and validity.
