Australia has just rescheduled two drugs controlled under the United Nations Psychotropic Drug Conventions, psilocybin and MDMA, as treatments for treatment-resistant depression and post-traumatic stress disorder respectively. This feature explores the reasons for these developments, the opportunities and challenges they provide to psychiatry communities and how along with health systems these communities might respond to these developments.

Background: Individuals with schizophrenia face high mortality risks. The effects of lipid-modifying agents on this risk remain understudied.

Aim: This study was conducted to investigate the effects of lipid-modifying agents on mortality risk in people with schizophrenia.

Method: This nationwide cohort study collected the data of people with schizophrenia from Taiwan's National Health Insurance Research Database for the period between 1 January 2001 and 31 December 2019. Multivariable Cox proportional hazards regression with a time-dependent model was used to estimate the hazard ratio for mortality associated with each lipid-modifying agent.

Results: This study included 110 300 people with schizophrenia. Of them, 22 528 died (19 754 from natural causes and 1606 from suicide) during the study period, as confirmed using data from Taiwan's national mortality database. The use of lipid-modifying agents was associated with reduced risks of all-cause (adjusted hazard ratio [aHR]:0.37; P < 0.001) and natural (aHR:0.37; P < 0.001) mortality during a 5-year period. Among the lipid-modifying agents, statins and fibrates were associated with reduced risks of all-cause mortality (aHRs:0.37 and 0.39, respectively; P < 0.001 for both) and natural mortality (aHRs: 0.37 and 0.42, respectively; P < 0.001 for both). Notably, although our univariate analysis indicated an association between the use of lipid-modifying agents and a reduced risk of suicide mortality, the multivariate analysis revealed no significant association.

Conclusions: Lipid-modifying agents, particularly statins and fibrates, reduce the risk of mortality in people with schizophrenia. Appropriate use of lipid-modifying agents may bridge the mortality gap between these individuals and the general population.

There is a lack of data on mental health service utilisation and outcomes for people with experience of forced migration living in the UK. Details about migration experiences documented in free-text fields in electronic health records might be harnessed using novel data science methods; however, there are potential limitations and ethical concerns.

Background: The longitudinal course of late-life depression remains under-studied.

Aims: To describe transitions along the depression continuum in old age and to identify factors associated with specific transition patterns.

Method: We analysed 15-year longitudinal data on 2745 dementia-free persons aged 60+ from the population-based Swedish National Study on Aging and Care in Kungsholmen. Depression (minor and major) was diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision; subsyndromal depression (SSD) was operationalised as the presence of ≥2 symptoms without depression. Multistate survival models were used to map depression transitions, including death, and to examine the association of psychosocial (social network, connection and support), lifestyle (smoking, alcohol consumption and physical activity) and clinical (somatic disease count) factors with transition patterns.

Results: Over the follow-up, 19.1% had ≥1 transitions across depressive states, while 6.5% had ≥2. Each additional somatic disease was associated with a higher hazard of progression from no depression (No Dep) to SSD (hazard ratio 1.09; 1.07-1.10) and depression (Dep) (hazard ratio 1.06; 1.04-1.08), but also with a lower recovery (HR_{SSD-No Dep} 0.95; 0.93-0.97 [where 'HR' refers to 'hazard ratio']; HR_{Dep-No Dep} 0.96; 0.93-0.99). Physical activity was associated with an increased hazard of recovery to no depression from SSD (hazard ratio 1.49; 1.28-1.73) and depression (hazard ratio 1.20; 1.00-1.44), while a richer social network was associated with both higher recovery from (HR_{SSD-No Dep} 1.44; 1.26-1.66; HR_{Dep-No Dep} 1.51; 1.34-1.71) and lower progression hazards to a worse depressive state (HR_{No Dep-SSD} 0.81; 0.70-0.94; HR_{No Dep-Dep} 0.58; 0.46-0.73; HR_SSD-Dep 0.66; 0.44-0.98).

Conclusions: Older people may present with heterogeneous depressive trajectories. Targeting the accumulation of somatic diseases and enhancing social interactions may be appropriate for both depression prevention and burden reduction, while promoting physical activity may primarily benefit recovery from depressive disorders.

This editorial describes the Cass Review findings and the extraordinary challenge we all face in managing uncertainty amid a toxic and highly polarised debate. Children and young people will only get the best care if patients and professionals join forces to seek answers collaboratively and respectfully.
