RESUMO
Colonial thinking runs deep in psychiatry. Recent anti-racist statements from the APA and RCPsych are to be welcomed. However, we argue that if it is to really tackle deep-seated racism and decolonise its curriculum, the discipline will need to critically interrogate the origins of some of its fundamental assumptions, values and priorities. This will not be an easy task. By its very nature, the quest to decolonise is fraught with contradictions and difficulties. However, we make the case that this moment presents an opportunity for psychiatry to engage positively with other forms of critical reflection on structures of power/knowledge in the field of mental health. We propose a number of paths along which progress might be made.

OBJECTIVE: Peptide YY(3-36) (PYY(3-36)), a Y2 receptor agonist, and oxyntomodulin, a glucagon-like peptide 1 (GLP-1) receptor agonist, are cosecreted by intestinal L-cells after each meal. Separately each hormone acts as an endogenous satiety signal and reduces appetite in humans when infused intravenously. The aim of the current study was to investigate whether the anorectic effects of PYY(3-36) and oxyntomodulin can be additive. RESEARCH DESIGN AND METHODS: Twelve overweight or obese human volunteers underwent a randomized, double-blinded, placebo-controlled study. An ad libitum test meal was used to measure energy intake during intravenous infusions of either PYY(3-36) or oxyntomodulin or combined PYY(3-36)/oxyntomodulin. RESULTS: Energy intake during coadministration of PYY(3-36) and oxyntomodulin was reduced by 42.7% in comparison with the saline control and was significantly lower than that during infusions of either hormone alone. CONCLUSIONS: The anorectic effects of PYY(3-36) and oxyntomodulin can be additive in overweight and obese humans. Coadministration of Y2 receptor agonists and GLP-1 receptor agonists may be a useful treatment strategy for obesity.
