Delirium Café: interactive learning to enhance delirium care.

PURPOSE: The aim of Delirium Café was to try a new learning method to increase awareness of delirium and improve delirium care in an acute hospital setting in Helsinki, Finland. METHOD: World Café-an active learning method, with four facilitators and four stations covering important aspects of delirium recognition and management, was used. RESULTS: 22 junior doctors and 4 members of the senior staff participated in the event on 13th of March 2019, the World Delirium Awareness Day (WDAD). Nobody dropped out during the 1 h training. Feedback on the educational method was positive. CONCLUSION: Delirium Café seems to be both feasible and applicable as a new interactive-learning method in postgraduate medical teaching.

Morphological characterization of intra-articular HMGB1 expression during the course of collagen-induced arthritis.

High-mobility group chromosomal box protein 1 (HMGB1) is a structural nuclear protein that promotes inflammation when present extracellularly. Aberrant, extracellular HMGB1 expression has been demonstrated in human and experimental synovitis. The aim of the present study was to elucidate the temporal and spatial expression of HMGB1 compared to that of the central mediators tumor necrosis factor (TNF) and interleukin-1-beta (IL-1beta) during the course of collagen-induced arthritis. Thus, Dark Agouti rats were immunized with homologous type II collagen and synovial tissue specimens were obtained at various time points prior to and during the course of clinical arthritis. Local cytokine responses were assessed by immunohistochemistry and by in situ hybridization. We demonstrate a distinct nuclear expression of HMGB1 at early disease-preceding time points. Preceding clinical onset by a few days, cytoplasmic HMGB1 expression was evident in synoviocytes within the non-proliferative lining layer. Pronounced cytoplasmic and additional extracellular HMGB1 expression coincided with the progression of clinical disease. In advanced arthritis, the number of cells with cytoplasmic HMGB1 expression was quantitatively comparable to that of cells expressing TNF and IL-1beta. Interestingly, although HMGB1 was abundantly expressed throughout the inflamed synovium at a protein level, upregulation of HMGB1 mRNA was restricted mainly to areas of cartilage and bone destruction. In conclusion, these new findings implicate a role for HMGB1 in both inducing and perpetuating inflammatory events of significant importance in the destructive processes in chronic arthritis.
