Background: Professional identity formation (PIF) as a general practitioner (GP) enhances the experience of meaning at work, reduces burnout, promotes patient-centred decision making and strengthens advocacy for the unique role of family medicine within the healthcare system. Unfortunately, there is insufficient emphasis on PIF in GP residency programs; it often remains a hidden curriculum. External factors limiting GP trainees' exposure to their own general practice community of practice further impede PIF.

Introduction: Allopurinol, the first-line treatment for chronic gout, is a common causative drug for severe cutaneous adverse reactions (SCAR). HLA-B*58:01 allele was strongly associated with allopurinol-induced SCAR in Asian countries such as Taiwan, Japan, Thailand and Malaysia. HLA-B*58:01 screening before allopurinol initiation is conditionally recommended in the Southeast-Asian population, but the uptake of this screening is slow in primary care settings, including Malaysia.

Educational programs are integral to building health research ethics (HRE) capacity, but no outcomes framework exists to guide them. We empirically developed a competency framework for health research ethics education-the Framework for Research Ethics Studies Competencies and Outcomes (FRESCO)-using mixed methods, including group concept mapping and a survey of international experts. FRESCO includes seven competency domains: (1) Foundational Knowledge; (2) Laws, Regulations, Guidelines, and Policies for Research Oversight; (3) Ethical-Issue Identification, Analysis, and Resolution; (4) Engagement, Communication, and Advocacy; (5) Lifelong Learning, Education, Research, and Scholarship; (6) Coordination, Stewardship, and Responsiveness in HRE Systems; and (7) Impartiality, Honesty, and Responsibility.
