Background And Aims: Vedolizumab [VDZ] is a monoclonal antibody directed against the α4β7 integrin heterodimer, approved for patients with inflammatory bowel diseases [IBD]. This study aimed at identifying immunological variables associated with response to vedolizumab in patients with ulcerative colitis [UC] and Crohn's disease [CD].
Methods: This is a phase IV explorative prospective interventional trial. IBD patients received open-label VDZ at Weeks 0, 2, 6, and 14. Patients with a clinical response at Week 14 were maintained with VDZ up to Week 54. At Weeks 0 and 14, their peripheral blood was obtained and endoscopy with biopsies was performed. The Week 14 clinical response and remission, Week 54 clinical remission, and Week 14 endoscopic response were evaluated as endpoints of the study. The expression of surface markers, chemokine receptors, and α4β7 heterodimer in peripheral blood and lamina propria lymphocytes was assessed by flow cytometry. A panel of soluble mediators was assessed in sera at baseline and at Week 14 by 45-plex.
Results: A total of 38 IBD patients [20 UC, 18 CD] were included in the study. At Week 14, the clinical response and remission rates were 87% and 66%, respectively. Higher baseline levels of circulating memory Th1 cells were strongly associated with clinical response at Week 14 [p = 0.0001], whereas reduced baseline levels of lamina propria memory Th17 and Th1/17 cells were associated with endoscopic response. Immunological clusters were found to be independently associated with vedolizumab outcomes at multivariable analysis. A panel of soluble markers, including IL17A, TNF, CXCL1, CCL19 for CD and G-CSF and IL7 for UC, associated with vedolizumab-induced Week 54 clinical remission.
Conclusions: The results of this exploratory study uncovered a panel of circulating and mucosal immunological variables associated with response to treatment with vedolizumab.

Background: Bullous pemphigoid (BP) is a common autoimmune subepidermal bullous disease. Dupilumab, an IL-4/IL-13 inhibitor, represents a novel therapeutic approach for BP, but real-world long-term data in super-elderly patients are limited.
Methods: This retrospective, single-center observational study included super-elderly BP patients (≥80 years) receiving dupilumab monotherapy from September 2022 to September 2024.

Background: Current management of pediatric cutaneous abscesses involves either spontaneous healing by secondary intention or suturing through tertiary intention, which are often lengthy processes that cause discomfort and distress among children. As it is noninvasive and simple, a novel zipper device is widely used for the primary wound closure of surgical incisions.
Objective: To describe the effectiveness of novel zipper device use for pediatric cutaneous abscess wound closure in an outpatient context.

Background: Emotion dysregulation is a central feature in trauma-associated disorders such as posttraumatic stress disorder (PTSD) and borderline personality disorder (BPD). However, it remains unclear whether emotion dysregulation is a transdiagnostic phenomenon closely linked to childhood trauma, or if disorder-specific alterations in emotion processing exist. Following a multimethodological approach, we aimed to assess and compare the reactivity to and regulation of emotions between patients with BPD and PTSD, as well as healthy controls, and identify associations with childhood trauma.

Background: Nursing interns frequently encounter role ambiguity due to a mismatch between their expectations of the professional nursing role and the actual responsibilities they face in clinical settings. While clinical rotations during the internship year are intended to enhance clinical confidence and competence, such ambiguity can undermine these goals.
Objective: To examine the relationship between internship clinical rotation and role ambiguity among nursing interns.
