RATIONALE, AIMS AND Type 2 diabetes (T2D) is an archetypical chronic condition of significant prevalence. Yet the concept of cure in the context of T2D reveals an interplay between the medical imagination and clinical realities that can shift the course of a patient's care. ⋯ Lay epistemologies of cure tend to be focused on modifying the experience of having T2D, while professional epistemologies tend to focus on modifying the disease through medical treatment. The objective of this study is to explore the role of the concept of cure in the context of type 2 diabetes, a model for chronic disease.

In the context of a pandemic, the rapid development of clinical practice guidelines (CPGs) is critical. The guideline development process includes prioritization of the guideline topic, questions and health outcomes. This case study describes the application of a new methodology to prioritize questions and rate the importance of health outcomes for a COVID-19 dental guideline. ⋯ This case study demonstrated that this approach provides a rigorous and transparent methodology to conduct the prioritizations of guideline topics, questions and health outcomes.

It is generally believed that evidence from low quality of evidence generate inaccurate estimates about treatment effects more often than evidence from high (certainty) quality evidence (CoE). As a result, we would expect that (a) estimates of effects of health interventions initially based on high CoE change less frequently than the effects estimated by lower CoE (b) the estimates of magnitude of effect size differ between high and low CoE. Empirical assessment of these foundational principles of evidence-based medicine has been lacking. ⋯ We found that low-quality evidence changes more often than high CoE. However, the effect size did not systematically differ between the studies with low versus high CoE. The finding that the effect size did not differ between low and high CoE indicate urgent need to refine current EBM critical appraisal methods.

In the treatment of atrial fibrillation (AF), anticoagulant medications such as warfarin and rivaroxaban are commonly prescribed to reduce the risk of ischaemic strokes, and other thromboembolic events. Research has highlighted advantages and disadvantages of each of these medications, but there remains an absence of qualitative evidence regarding the lived experiences of AF patients. The present study helps address this gap and obtain a greater understanding of the patient experience and beliefs surrounding their anticoagulant medication. ⋯ Positive perceptions of one anticoagulant medication (ACM) and distrust of alternatives may influence patients' confidence in switching medications. This is potentially problematic where there is a lack of patient engagement in medication changes, as seen during the COVID pandemic. Gaps in patient understanding of anticoagulation, including lack of clarity around medications selection and misconceptions about treatment, were evident. By addressing these misconceptions, clinicians may be better positioned to support people with AF in self-management of their ACM.
