Inequalities and power imbalances are maintained by person-blaming and the invisibility of structural inequality. Opportunities to recognise the effects of being privileged and working within a medical culture that compounds such inequality may be squandered without curiosity and action.Inequalities and power imbalances are maintained by person-blaming and the invisibility of structural inequality.

Bariatric surgical procedures are being commonly performed increasingly, and many surgical candidates are concomitantly taking psychotropic medication. This paper aims to elucidate issues when prescribing psychiatric medication in this setting of substantial anatomical and physiological change. A hand search of the literature to assess the current understanding of effects of various bariatric procedures on the bioavailability of psychotropic medication. Predominantly malabsorptive bariatric procedures may reduce bioavailability of some but not all commonly used psychiatric medications. There is minimal information about the effects of the most commonly performed surgery, vertical sleeve gastrectomy. Lithium prescription and monitoring requires caution. There is limited guidance for prescription for psychotropic medication in the bariatric surgery patient group, and vigilance for unexpected adverse effects or altered efficacy is warranted.There is limited guidance for prescription for psychotropic medication in the bariatric surgery patient group, and vigilance for unexpected adverse effects or altered efficacy is warranted. To date, specific parent- and child-defined anxiety disorders associated with dysthymic disorder (DD; DSM-5 persistent depressive disorder equivalent) with and without major depressive disorder (MDD) have not been investigated in children and adolescents. In a cross-sectional study, we compared point prevalence rates of parent- and child-reported anxiety disorders in DD alone ( = 154), MDD alone ( = 29), comorbid DD and MDD ( = 130) and anxiety disorders alone ( = 126) groups. DD alone and MDD alone did not differ with respect to comorbid anxiety disorders from parent and child reports, while parent-reported panic disorder (PD) was significantly increased in the DD and MDD group compared to the other three groups as was child-reported post-traumatic stress disorder (PTSD) compared to the MDD alone and anxiety disorders alone groups. In contrast, specific phobia (SpPh) was significantly increased in the anxiety disorders alone group compared to the DD and MDD group. The findings suggest that specific fear-related anxiety disorders, especially parent-reported PD and child-reported PTSD, may aid the early recognition of DD and MDD.The findings suggest that specific fear-related anxiety disorders, especially parent-reported PD and child-reported PTSD, may aid the early recognition of DD and MDD. Coronavirus (COVID-19) has led to high levels of psychological distress in the community. This study aimed to examine whether emergency departments (EDs) also recorded a rise in mental health presentations. Changes in the number, and type, of mental health presentations to Western Australia EDs were examined between January and May 2020, and compared to 2019. Data showed an unexpected decrease in the number of mental health presentations, compared to 2019, which was temporally coincident with the rise in local COVID-19 cases. Presentations for anxiety and panic symptoms, and social and behavioural issues, increased by 11.1% and 6.5%, respectively, but suicidal and self-harm behaviours decreased by 26%. A rise in local COVID-19 cases was associated with a decrease in mental health presentations to EDs. This has important implications for the planning and provision of healthcare services in the current pandemic.A rise in local COVID-19 cases was associated with a decrease in mental health presentations to EDs. find more This has important implications for the planning and provision of healthcare services in the current pandemic.During mating season, males of synchronous firefly species flash in unison within swarms of thousands of individuals. These strongly correlated collective displays have inspired numerous mathematical models to explain how global synchronous patterns emerge from local interactions. Yet, experimental data to validate these models remain sparse. To address this gap, we develop a method for three-dimensional tracking of firefly flashes, using a stereoscopic set-up of 360-degree cameras. We apply this method to record flashing displays of the North American synchronous species Photinus carolinus in its natural habitat as well as within controlled environments, and obtain the three-dimensional reconstruction of flash occurrences in the swarm. Our results show that even a small number of interacting males synchronize their flashes; however, periodic flash bursts only occur in groups larger than 15 males. Moreover, flash occurrences are correlated over several metres, indicating long-range interactions. While this suggests emergent collective behaviour and cooperation, we identify distinct individual trajectories that hint at additional competitive mechanisms. These reveal possible behavioural differentiation with early flashers being more mobile and flashing longer than late followers. Our experimental technique is inexpensive and easily implemented. It is extensible to tracking light communication in various firefly species and flight trajectories in other insect swarms.
