Sustainability in orthodontics: Challenges and opportunities for improving our environmental impact.

OBJECTIVE: To highlight the potential environmental impact of different aspects of orthodontic care in the United Kingdom, outline the major barriers and challenges to reducing this impact, and summarise the possible action that could help the orthodontic community to tackle the climate change crisis. IMPACT: Travel, procurement and supply, material use, waste management, energy use and water consumption within dentistry have a considerable effect on the environment. There are, however, marked knowledge gaps pertaining to the impact of orthodontic treatment. CHALLENGES: The lack of awareness of the NHS contribution to the carbon footprint and net-zero goals among healthcare workers, the NHS backlogs and budget cuts, and cross-infection control requirements particularly following the COVID-19 pandemic are some of the many challenges to making healthcare delivery more sustainable. OPPORTUNITIES: By considering the triple bottom line (social, environmental and economic), incorporating the four Rs (Reduce, Reuse, Recycle, Rethink), taking practical action, including steps to educate ourselves and the wider team, and to promote research on environmental sustainability, we can get one step closer to reaching the NHS net-zero goals. CONCLUSION: Climate change is a global health threat with multiple contributors associated with orthodontic treatment delivery, which can be tackled on an individual, organisational and system level.

The NSW Emergency Psychiatry Network.

Emergency Psychiatry is evolving. In an environment that lacks a clear evidence base, and where a constellation of factors is driving up Emergency Department presentation rates and lengths of stay, several stakeholders are working towards and clamouring for change. With the goal of collaborating with such parties, we believe Emergency Psychiatrists should position themselves to establish and advocate for best-practice change in culture, research, clinical care and training, and funding in the provision of mental health crisis care. To this end, we have formed the NSW Emergency Psychiatry Network, a group of Emergency Psychiatrists with a broad experience in a range of settings, from tertiary metropolitan emergency facilities with access to subspecialty psychiatric services, to rural and remote emergency settings with sporadic in-reach from local mental health services and telehealth. We unanimously recognise the need to upskill both Emergency Department and Mental Health clinicians in crisis care, and the need for committed, evidence-based Mental Health resourcing within Emergency Departments.

The impact of smoking cessation on schizophrenia and major depression.

OBJECTIVE: This review sought to determine whether quitting smoking behaviour places people with a history of schizophrenia or major depression at risk of worsening symptoms or relapse. METHOD: Literature searches of Embase, MEDLINE, the Cochrane Library and PsycINFO. RESULTS: Six studies involving 735 people diagnosed with schizophrenia, schizoaffective disorder or psychotic disorder did not find significant change in mental health status after quitting smoking. Five out of six studies involving 1,293 people with a history of major depression did not find an increased risk of depression with abstinence from smoking, while one study did. Two of these studies found an improvement in depressive symptoms among quitters. CONCLUSIONS: There is no published evidence to support the hypothesis that quitting smoking is harmful to the mental health of people with schizophrenia. Smoking cessation does not appear to place smokers with a history of major depression at increased risk of worsening symptoms nor relapse, and may even improve their mood. Psychiatrists and other mental health professionals should provide their patients with the same level of support to quit smoking that is given to the rest of the population.
