Cortisol awakening response and acute stress reactivity in First Nations people

First Nations people globally have a higher incidence of mental disorders and non-communicable diseases. These health inequalities are partially attributed to a complex network of social and environmental factors which likely converge on chronic psychosocial stress. We hypothesized that alterations in stress processing and the regulation of the hypothalamic-pituitary-adrenal axis might underlie health disparities in First Nations people. We assessed the cortisol awakening response and the dynamic response to a laboratory induced psychosocial stress of young Indigenous tertiary students (n = 11, mean age 23.82 years) and non-Indigenous students (n = 11) matched for age and gender. Indigenous participants had a blunted cortisol awakening response (27.40 (SD 35.00) vs. 95.24 (SD 55.23), p = 0.002), which was differentially associated with chronic experience of stress in Indigenous (r = −0.641, p = 0.046) and non-Indigenous (r = 0.652, p = 0.03) participants. The cortisol response to the laboratory induced psychosocial stress did not differ between groups. Self-reported racial discrimination was strongly associated with flattened cortisol response to stress (r = −0676, p = 0.022) and with heart rate variability (r = 0.654, p = 0.040). Our findings provide insight into potential biological factors underlying health discrepancies in ethnic minority groups

Training a fit-for-purpose rural health workforce for low- and middle-income countries (LMICs): how do drivers and enablers of rural practice intention differ between learners from LMICs and high income countries?

Equity in health outcomes for rural and remote populations in low- and middle-income countries (LMICs) is limited by a range of socio-economic, cultural and environmental determinants of health. Health professional education that is sensitive to local population needs and that attends to all elements of the rural pathway is vital to increase the proportion of the health workforce that practices in underserved rural and remote areas. The Training for Health Equity Network (THEnet) is a community-of-practice of 13 health professional education institutions with a focus on delivering socially accountable education to produce a fit-for-purpose health workforce. The THEnet Graduate Outcome Study is an international prospective cohort study with more than 6,000 learners from nine health professional schools in seven countries (including four LMICs; the Philippines, Sudan, South Africa and Nepal). Surveys of learners are administered at entry to and exit from medical school, and at years 1, 4, 7, and 10 thereafter. The association of learners' intention to practice in rural and other underserved areas, and a range of individual and institutional level variables at two time points—entry to and exit from the medical program, are examined and compared between country income settings. These findings are then triangulated with a sociocultural exploration of the structural relationships between educational and health service delivery ministries in each setting, status of postgraduate training for primary care, and current policy settings. This analysis confirmed the association of rural background with intention to practice in rural areas at both entry and exit. Intention to work abroad was greater for learners at entry, with a significant shift to an intention to work in-country for learners with entry and exit data. Learners at exit were more likely to intend a career in generalist disciplines than those at entry however lack of health policy and unclear career pathways limits the effectiveness of educational strategies in LMICs. This multi-national study of learners from medical schools with a social accountability mandate confirms that it is possible to produce a health workforce with a strong intent to practice in rural areas through attention to all aspects of the rural pathway

Muddying the waters? A false positive case of autoimmune psychosis

Objective: To discuss challenges with the diagnosis of autoimmune psychosis (AP) in people with chronic psychotic disorders. Method: We present a case of a 23-year-old man with an exacerbation of treatment-refractory psychosis after receiving intravenous immunoglobulin (IVIG) for suspected AP, diagnosed 4 years after the onset of psychosis. We highlight the diagnostic and management challenges in such cases. Results: The diagnosis of AP in people with long-standing illness relies on the interpretation of non-specific clinical and laboratory findings in individuals with psychosocial problems and challenges of acceptance and adherence to complex medical investigations and treatments. Equivocal results from investigations undertaken without logical clinical reasoning can lead to inappropriate interventions that are costly and can cause iatrogenic harm. Conclusion: Psychiatrists should restrict screening for antineuronal antibodies in people with chronic psychosis to those with higher risk features such as persistent treatment refractory symptoms with concurrent neurological signs and symptoms. Further research informing the clinical circumstances for antineuronal antibody testing is needed
