Twenty-first-century trade policy is complex and affects society and population health in direct and indirect ways. Without doubt, trade policy influences the distribution of power, money, and resources between and within countries, which in turn affects the natural environment; people's daily living conditions; and the local availability, quality, affordability, and desirability of products (e.g., food, tobacco, alcohol, and health care); it also affects individuals' enjoyment of the highest attainable standard of health. In this article, we provide an overview of the modern global trade environment, illustrate the pathways between trade and health, and explore the emerging twenty-first-century trade policy landscape and its implications for health and health equity. We conclude with a call for more interdisciplinary research that embraces complexity theory and systems science as well as the political economy of health and that includes monitoring and evaluation of the impact of trade agreements on health.

Four formal rounds of Trans‐Pacific Partnership Agreement (TPPA) negotiations took place in 2010. They involved over 200 officials from Australia, the United States, New Zealand, Chile, Singapore, Brunei, Peru, Vietnam and Malaysia. Future negotiations officially are set to include three issues with public health and medicines policy implications for Australia and our region: ➢ways to approach regulatory coherence and transparency; ➢how to benefit multinational and small–medium enterprises; and ➢multilateral investor–state dispute settlement. US‐based multinational pharmaceutical companies are lobbying for TPPA provisions like those in the Australia–US Free Trade Agreement, which reduce government cost‐effectiveness regulatory control of pharmaceuticals, threatening equitable access to medicines. They also advocate increased TPPA intellectual monopoly privilege protection, which will further limit the development of Australian generic medicine enterprises and restrict patient access to cheap, bioequivalent prescription drugs. Of particular concern is that proposed TPPA multilateral investor–state dispute settlement procedures would allow US corporations (as well as those of other TPPA nations) to obtain damages against Australian governments through international arbitral proceedings if their investments are impeded by Australian public health and environment protection legislation.

Paramedics form part of the frontline response to mental health care in the community. Changes to mental health laws across the country have seen an increase in the role and responsibilities paramedics have in assessing, treating and managing mental health patients. The increasing complexity of the paramedic role associated with these changes requires a clear understanding of the legal, ethical and organisational requirements that accompany them. This paper will examine the relevant legislative principles and ethical dilemmas that are raised by these changes and will demonstrate the need for further research to assist in the development and implementation of strategies to assist paramedics in providing optimal patient care to a vulnerable section of the community.

Despite advances in technology being a driver of paramedic professional development, particularly over the past decade, the introduction of new forms of technology appears to have presented paramedics with some professional challenges. Paramedics, pre-hospital clinicians, and ambulance service providers in both the United Kingdom and Australia, have begun using social media technology to communicate what they do to the general public. Unfortunately some of the material that has been communicated appears to breach professional standards of practice, and therefore has the potential to cause harm to the patient, the individual paramedic, and the paramedic profession more broadly. This article will present the rationale behind why this behaviour is unprofessional, ethically and legally unsound, and why it must cease. We offer a tool that will assist paramedics, and other healthcare professionals, to practise safe and professional social media use in their workplace.

This short commentary aims to begin the discussion about the legal and ethical changes to paramedic practice that are likely to occur over the next six to twelve months in response to the COVID-19 crisis.
