Background: Patients with inflammatory bowel disease (IBD) in clinical and endoscopic remission may still experience disease relapse. Therefore, there is a need to identify outcome predictors. Recently, the role of neutrophils in predicting outcomes in ulcerative colitis (UC) has been highlighted. Furthermore, the impairment of intestinal barrier plays a key role in forecasting disease outcomes in IBD.
Objective: This observational study aimed to assess the predictive role of neutrophils according to tissue localization and intestinal barrier protein expression in IBD.
Methods: IBD patients in clinical remission who underwent colonoscopy between January 2020 and June 2022 at two tertiary referral centres were enrolled. Patients with Mayo Endoscopic Score ≤1 (UC) and Simple Endoscopic Score ≤6 (Crohn's disease) were included. Histological activity was assessed using validated scores. Experienced pathologists evaluated neutrophil localization in the epithelium and lamina propria and immunohistochemical expression of Claudin-2 and junctional adhesion molecule A (JAM-A).
Results: Of 60 UC and 76 CD patients, 59.7% had histological activity. 25.8% of patients developed an adverse outcome within 12 months. Neutrophils in the epithelium predicted adverse outcomes for UC (hazard ratio [HR] 5.198, p = 0.01) and CD (HR 4.377, p = 0.03) patients in endoscopic remission. Claudin-2 expression correlated with endoscopic and histological activity and predicted outcomes in UC. Similar results were found for JAM-A in CD despite this protein showing less specificity as a barrier predictor of outcome.
Conclusion: This study highlights the potential role of epithelial neutrophil localization and Claudin-2 'leaky gut' expression as tools for predicting IBD outcomes and guiding further patient-tailored therapy.

Background: Hypnosis sedation has recently been used for anesthesia in breast oncologic surgery.
Methods: Between January 2017 and October 2019, 284 patients from our Breast Clinic (Cliniques Universitaires Saint-Luc, Université Catholique de Louvain) and from the Jolimont Hospital were prospectively included in an interventional non-randomized study approved by our two local ethics committees and registered on clinicaltrials.gov (NCT03330117).

: Giant cell tumor of bone (GCTB) is a locally aggressive tumor. It accounts for only 5% of all bony tumors. Early diagnosis, and follow-up for recurrence is often difficult due to a lack of biogenetic markers.

Purpose: To ascertain the homing of monocytes and neutrophils in the epithelium versus stroma of HSV-1 infected corneas at different stages of infection and functional significance of their anatomical location in virus-infected corneas.
Methods: The corneas of C57BL/6J mice were infected with HSV-1 McKrae. Mice were euthanized on different days post-infection.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Background: Steroid-induced osteonecrosis of the femoral head (SIONFH) is a universal hip articular disease and is very hard to perceive at an early stage. The understanding of the pathogenesis of SIONFH is still limited, and the identification of efficient diagnostic biomarkers is insufficient. This research aims to recognize and validate the latent exosome-related molecular signature in SIONFH diagnosis by employing bioinformatics to investigate exosome-related mechanisms in SIONFH.
