    Abstract A middle-aged woman presented with a history of symptoms of depression with psychotic features severely affecting her physical health. Neuroimaging of her brain suggested pathological changes out of keeping with her age, leading to further investigations including genetic testing for cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL). Anti-N-methyl-D-aspartate receptor (NMDAR) encephalitis was also considered as a differential diagnosis as an initial serum test for anti-NMDAR autoantibodies was positive. Her symptoms resolved following treatment with electroconvulsive therapy. Despite her initial neuroimaging, her genetic test for CADASIL was negative and her subsequent test for anti-NMDAR autoantibodies was negative, suggesting that the initial test may have been a false positive.

    Abstract The NOD mouse develops spontaneous type 1 diabetes, with some features of disease that are very similar to the human disease. However, a proportion of NOD mice are naturally protected from developing diabetes, and currently, studies characterizing this cohort are very limited. Here, using both immunofluorescence and multiparameter flow cytometry, we focus on the pancreatic islet morphology and immune infiltrate observed in naturally protected NOD mice. We show that naturally protected NOD mice are characterized by an increased frequency of insulin-containing, smaller-sized, pancreatic islets. Although mice remain diabetes free, florid immune infiltrate remains. However, this immune infiltrate is skewed toward a regulatory phenotype in both T- and B-cell compartments. Pancreatic islets have an increased frequency of IL-10-producing B cells and associated cell surface markers. Resident memory CD69

    Abstract Objective: To increase the provision of clinical skills training during their psychiatry placement by providing a new teaching course to enhance both their clinical knowledge and communication skills.
    Method: We delivered a pilot teaching course consisting of five workshops (incorporating facilitated, 'near peer' role-play) during the students' psychiatry placement. Qualitative and quantitative feedback was collected pre- and post-course to allow for development of the course.
    Results: Data collected indicated that all students found the course a valuable addition to their usual teaching. They indicated that their confidence in their ability to assess patients with common clinical problems improved.
    Conclusions: This trainee-led course was easily integrated into the curriculum and received positive feedback from students. It may have enhanced students' confidence and readiness for exams but this will require further examination of objective assessments and ongoing research to establish this.

    Abstract This article describes the formation and work of a nationwide Qatar Simulation Consortium. In 2013, members included the schools of medicine, nursing, and allied health in Qatar, as well as the public health care system and a private, publicly funded hospital. The mission of the consortium is to foster simulation collaboration among health care and educational institutions and advance simulation education, research, and practice to align with current global standards.

    Abstract Aims/hypothesis: B cells play an important role in driving the development of type 1 diabetes; however, it remains unclear how they contribute to local beta cell destruction during disease progression. Here, we use gene expression profiling of B cell subsets identified in inflamed pancreatic tissue to explore their primary functional role during the progression of autoimmune diabetes.
    Methods: Transcriptional profiling was performed on FACS-sorted B cell subsets isolated from pancreatic islets and the pancreatic lymph nodes of NOD mice.
    Results: B cells are highly modified by the inflamed pancreatic tissue and can be distinguished by their transcriptional profile from those in the lymph nodes. We identified both a discrete and a core shared gene expression profile in islet CD19
    Conclusions/interpretation: Our study provides a detailed transcriptional analysis of islet B cells. Specific gene signatures and interaction networks have been identified that point towards a functional role for B cells in driving autoimmune diabetes.

    Abstract Introduction: In this study, we report a novel therapeutic approach using B lymphocytes to attract islet-specific T cells in the non-obese diabetic (NOD) mouse model and prevent the development of autoimmune diabetes. Rather than using the antibody receptor of B cells, this approach utilizes their properties as antigen-presenting cells to T cells.
    Methods: Purified splenic B cells were treated with lipopolysaccharide, which increases regulatory B (Breg) cell function, then electroporated with mRNA encoding either chimeric MHC-I or MHC-II molecules covalently linked to antigenic peptides. Immunoregulatory functions of these engineered B cells (e-B cells) were tested by
    Results: The e-B cells expressing chimeric MHC-I-peptide inhibited antigen-specific CD8
    Discussion: MHC-peptide chimeric e-B cells interacted with pathogenic T cells, and protected the host from autoimmune diabetes, in a mouse model. Thus, we have successfully expressed MHC-peptide constructs in B cells that selectively targeted antigen-specific cells, raising the possibility that this strategy could be used to endow different protective cell types to specifically regulate/remove pathogenic cells.

    Abstract Regulatory B cells (Bregs) suppress and reduce autoimmune pathology. However, given the variety of Breg subsets, the role of Bregs in the pathogenesis of type 1 diabetes is still unclear. Here, we dissect this fundamental mechanism. We show that natural protection from type 1 diabetes in nonobese diabetic (NOD) mice is associated with increased numbers of IL-10-producing B cells, while development of type 1 diabetes in NOD mice occurs in animals with compromised IL-10 production by B cells. However, B cells from diabetic mice regain IL-10 function if activated by the innate immune receptor TLR4 and can suppress insulin-specific CD8 T cells in a dendritic cell (DC)-dependent, IL-10-mediated fashion. Suppression of CD8 T cells is reliant on B-cell contact with DCs. This cell contact results in deactivation of DCs, inducing a tolerogenic state, which in turn can regulate pathogenic CD8 T cells. Our findings emphasize the importance of DC-Breg interactions during the development of type 1 diabetes.

    Abstract Background: Literature suggests interprofessional education (IPE) and education about complementary therapies for health sciences students may be effectively combined.
    Methods: A novel 30-hour, 10-week course for interprofessional undergraduate health sciences students combining IPE and complementary therapies learning objectives was developed and offered in 2012 (N = 71), 2013 (N = 120) and 2014 (N = 140). Pre-post mixed methods measurement occurred in three groups: one taking combined IPE-complementary therapies curriculum, and two control groups (one following non-specialized IPE curriculum, and one following combined IPE-continuing care curriculum). The students' attitudinal changes towards IPE and complementary therapies, and their comfort collaborating with students in other health sciences programs were measured using scales. Qualitative evaluation was conducted via content analysis of team-based reflective essays of their opinions towards what they learned about IPE and complementary therapies, and how it changed during the course.
    Results: Quantitative results exhibited ceiling effects, revealing little change or difference between groups on all measures, with the exception of the Health Professional Collaborative Competency Perception Scale which indicated the students taking the IPE-complementary therapies course reported increased comfort collaborating in comparison with control groups. Qualitative results indicated students: increased their awareness and knowledge about complementary therapies, and were inspired to learn more, appreciated the need for collaboration and communication, desired to be more patient-centered, and wove concepts related to IPE and complementary therapies together.
    Conclusion: Combining IPE initiatives and basic complementary therapies education can save curricular time, and develop healthcare professionals who appear to be more ready to provide team-based, patient-centered care.
