Society for Cardiovascular Magnetic Resonance 2022 Cases of SCMR case series.

"Cases of SCMR" is a case series on the SCMR website (https://www.scmr.org) for the purpose of education. The cases reflect the clinical presentation, and the use of cardiovascular magnetic resonance (CMR) in the diagnosis and management of cardiovascular disease. The 2022 digital collection of cases are presented in this manuscript.

Oncologists' palliative care referral behaviour: testing utility of social exchange theory as an explanatory framework.

BACKGROUND: Adults and children with cancer are referred to palliative care infrequently or late. Oncologists often gatekeep these referrals. Social exchange theory is used to explain physician referral behaviour in various clinical settings. Its utility in a cancer palliative care setting is not known. METHODS: We used Karl Popper's hypothetico-deductive approach to test the hypothesis. The hypothesis was that social exchange theory is a helpful framework for explaining oncologists' palliative care referral behaviour in a cancer setting. The utility of the theoretical framework was tested against the empiric findings of a systematic review and original research. RESULTS: Most components of social exchange theory known to explain physician referral behaviour like beliefs about the provider or service, emotions triggered during the professional engagement, its symbolism and stigma, the complexity of the referral task, efforts needed to achieve it, its cost, benefit, and value were similar in a cancer setting. Empirical findings suggest that oncologists provided strategies and solutions to better palliative care integration instead of comparing their existing engagement with potential alternatives and choosing them. CONCLUSION: Social exchange theory was found to be helpful in explaining oncologists' palliative care referral behaviour. To further develop the social exchange theory based on the data used to test it, it is recommended to include feedback and solutions as a component of the theoretical framework alongside a comparison level for alternatives.

Paediatric oncologists' perspectives on Strategic solutions to develop Integrated Cancer Palliative Care: feedback intervention theory as an explanatory Framework.

BACKGROUND: Globally, children with cancer often experience delays in palliative care referral or are infrequently referred. Therefore, we conducted a qualitative study to gain insight from paediatric oncologists into what enables or deters palliative care referral. Strategic solutions to develop integrated palliative care was a critical study theme. In this paper, we have explained and interpreted these strategic solutions through the lens of feedback intervention theory. METHODOLOGY: The study findings were interpreted using Kumar's six-step approach that enabled systematic evaluation of a theory's appropriateness and alignment with the researcher's paradigm, methodology, and study findings. It also explained how theory informed analysis and elucidated challenges or the development of new models. The feedback intervention theory appraises the discrepancy between actual and desired goals and provides feedback to improve it. RESULTS: Strategic solutions generated from the study findings were coherent with the aspects elucidated in theory, like coping mechanisms, levels of feedback hierarchy, and factors determining the effect of the feedback intervention on performance. Paediatric oncologists suggested integrating palliative care providers in the team innocuously, improving communication between teams, relabelling palliative care as symptom control, and working with a skilled and accessible palliative care team. The paper proposes an infinite loop model developed from the study, which has the potential to foster integrated palliative care through excellent collaboration and continuous feedback. CONCLUSION: Applying feedback intervention theory can bridge the gap between actual and desired practice for integrated cancer palliative care in paediatric oncology.

The role of comprehensive stress cardiac MRI in autoimmune rheumatic disease: A review.

Cardiovascular disease is the leading cause of morbidity and mortality in patients with autoimmune rheumatic diseases. Much of this may be attributed to systemic inflammation resulting in coronary atherosclerosis and myocarditis. Cardiac magnetic resonance imaging is the gold standard for the evaluation of cardiac structure and function, including tissue characterization, which allows for detection of myocardial edema, inflammation, and fibrosis. Advances in parametric mapping and coronary flow reserve measurement techniques have the potential to change the diagnosis, risk stratification, and management of patients with autoimmune rheumatic diseases. We provide an overview of the current evidence and suggest potential future roles for the use of comprehensive cardiac magnetic resonance in patients with autoimmune rheumatic diseases in the field of cardio-rheumatology.
