RESUMO

A Code Red has been declared for the planet and human health. Climate change (e.g., increasing temperatures, adverse weather events, rising sea levels) threatens the planet's already declining ecosystems. Without urgent action, all of Earth's inhabitants face an existential threat. Health professions education should therefore prepare learners to not only practice in a changing world, but authentic educational activities should also develop competencies for global and planetary citizenship. Planetary health has been integrated across the five-year Bond University (Australia) medical curriculum. It begins in the second week of Year 1 and ends with a session on Environmentally Sustainable Healthcare in the General Practice rotation in the final year. The purpose of this article is to describe the outcomes of the first 5 years (2018-2022) of a learner-centered planetary health assignment, underpinned by the 2030 United Nations (UN) Sustainable Development Goals (SDGs), in the second year of a five-year medical program. Using systems and/or design thinking with a focus on SDG13 (Climate Action) plus a second SDG of choice, self-selected teams of 4-6 students submit a protocol (with feedback) to develop a deliverable "product" for an intended audience. Data analysis of the first 5 years of implementation found that the most frequently selected SDGs in addition to SDG13 were: SDG12 Sustainable Production and Consumption (41% of teams), mostly relating to healthcare emissions and waste; SDG3 Health and Well-being (22%), generally involving the impact of air pollution; and SDG6 Clean Water and Sanitation (15%). A survey at the concluding conference garnered student feedback across various criteria. The planetary health assignment is authentic in that teams provide solutions to address climate change. Where appropriate, final "products" are sent to local or federal ministers for consideration (e.g., policy proposals) or integrated into the curriculum (e.g., learning modules). We believe that the competencies, attitudes, and values fostered through engagement with planetary health. Throughout the medical program, as evidenced by their evaluations, stands students in good stead to be change agents, not only in clinical practice but in society. An awareness has been created about the need for planetary citizenship in addition to global citizenship.

RESUMO

Physiologically-based pharmacokinetic (PBPK) models usually include a large number of parameters whose values are obtained using in vitro to in vivo extrapolation. However, such extrapolations can be uncertain and may benefit from inclusion of evidence from clinical observations via parametric inference. When clinical interindividual variability is high, or the data sparse, it is essential to use a population pharmacokinetics inferential framework to estimate unknown or uncertain parameters. Several approaches are available for that purpose, but their relative advantages for PBPK modeling are unclear. We compare the results obtained using a minimal PBPK model of a canonical theophylline dataset with quasi-random parametric expectation maximization (QRPEM), nonparametric adaptive grid estimation (NPAG), Bayesian Metropolis-Hastings (MH), and Hamiltonian Markov Chain Monte Carlo sampling. QRPEM and NPAG gave consistent population and individual parameter estimates, mostly agreeing with Bayesian estimates. MH simulations ran faster than the others methods, which together had similar performance.

RESUMO

In colonial societies such as Canada the implications of colonialism and ethnocide (or cultural genocide) for ethical decision-making are ill-understood yet have profound implications in health ethics and other spheres. They combine to shape racism in health care in ways, sometimes obvious, more often subtle, that are inadequately understood and often wholly unnoticed. Along with overt experiences of interpersonal racism, Indigenous people with health care needs are confronted by systemic racism in the shaping of institutional structures, hospital policies and in resource allocation decisions. Above all, racism is a function of state law - of the unilateral imposition of the settler society law on Indigenous communities. Indeed, the laws, including health laws, are social determinants of the ill-health of Indigenous peoples. This article describes the problem of Indigenous ethnocide and explores its ethical implications. It thereby problematizes the role of law in health ethics.

RESUMO

In a recent article, Gross (2004) argues that physicians in decent societies have a civic duty to aid in the torturing of suspected terrorists during emergency conditions. The argument presupposes a communitarian society in which considerations of common good override questions of individual rights, but it is also utilitarian. In the event that there is a ticking bomb and no other alternative available for defusing it, torture must be used, and physicians must play their part. In an earlier article, Jones (1980) also argues in favour of physician participation in torture, going so far as to enthusiastically endorse the allocation of research resources as well to ensure that the ability to meet emergency situations is as efficient as scientifically possible. I argue against both these views and defend the absolute prohibition against torture generally, and against any participation by physicians in particular. I show that these arguments are incompatible with liberal or decent societies, and that the institutional requirements for making torture effective would constitute an unacceptable degradation both of medical ethics and practice, as well as of political institutions in general.

RESUMO

Annually, approximately 13,200 people in the U.S. are diagnosed with esophageal cancer and 12,500 die of this malignancy. Of new cases, 9,900 occur in men and 3,300 occur in women. In part I of this two-part series, we explore the epidemiology, presentation and progression, work-up, and surgical approaches for esophageal cancer. In the 1960s, squamous cell cancers made up greater than 90% of all esophageal tumors. The incidence of esophageal adenocarcinomas has risen considerably over the past two decades, such that they are now more prevalent than squamous cell cancer in the western hemisphere. Despite advances in therapeutic modalities for this disease, half the patients are incurable at presentation, and overall survival after diagnosis is grim. Evolving knowledge regarding the etiology of esophageal carcinoma may lead to better preventive methods and treatment options for early stage superficial cancers of the esophagus. The use of endoscopic ultrasound and the developing role of positron emission tomography have led to better diagnostic accuracy in this disease. For years, the standard of care for esophageal cancer has been surgery; there are several variants of the surgical approach. We will discuss combined modality approaches in part II of this series.
