Aotearoa New Zealand has one of the highest bowel cancer rates in the world. Bowel cancer incidence is increasing for Māori (the Indigenous people of Aotearoa), while trending downwards for non-Māori. Over half of Māori who get bowel cancer are diagnosed before the age of 60 years and are more likely than non-Māori to die within 2 years. Pacific people also experience bowel cancer inequities. In 2016, a national bowel screening programme for Aotearoa was announced, with an age range of 60-74 years. However, equity modelling showed that the proposed programme would disproportionately benefit non-Māori and that lowering the screening age for Māori and Pacific peoples to 50 years could achieve equal health gains. Over subsequent years, Māori cancer leaders advocated for policy change to lower the bowel screening age by 10 years for Māori. They used academic publications, presentations, letters, position statements, media stories and meetings with government leaders. Despite this advocacy, in 2020, the Government announced it was not going to lower the bowel screening age for Māori and Pacific peoples. The advocates persevered. They were supported in their efforts by new data that further confirmed the increasing bowel cancer incidence for Māori. In 2022, the Government committed to lowering the bowel cancer screening age to 50 for Māori and Pacific peoples. However, what followed was a tardy, phased rollout in only three regions. A year on, a new government embarked on a politically motivated agenda to reject ethnically targeted policies, with further significant equity changes to the programme announced. This paper summarises the lobbying efforts of cancer leaders and the government response, revealing structural and institutional racism, represented by inaction and active rejection of evidence-based advice. We describe the perseverance required to advocate for equity in the face of structural racism and the cost to Māori lives while inaction and racism persist.

Context: The Northern Territory (NT) is characterised by major health inequalities. A high proportion of the population is Indigenous, with poor socioeconomic conditions and a high burden of disease. The small NT population - 1% of the total Australian population - is dispersed over one-sixth of Australia's land mass. Given this very low population density and the geographical isolation of many small communities, access to services is often difficult. Medical workforce recruitment and retention have been persistent problems. Prior to 2011, NT residents who aspired to study medicine had to leave the NT. This was the only Australian state or territory that did not have the capacity for students to complete an entire medical degree within the jurisdiction. This article describes the development, implementation and outcomes of the Northern Territory Medical Program (NTMP), which commenced in Darwin in 2011. This was a major development of the Flinders University distributed program, which aimed to develop the medical workforce for the challenging NT environment. Issues: Based on evidence regarding the importance of selection in achieving rural workforce outcomes, and a national priority to graduate more Indigenous Australian doctors, NT residents and Indigenous applicants to the NTMP were prioritised in the selection process. Aspiring doctors would not now have to move interstate to study. The curriculum of Flinders University, based in Adelaide, South Australia, would be contextualised to the NT. The NTMP was developed and implemented in collaboration with Charles Darwin University, the major university in the NT. Lessons learned: Some of the lessons learned may be useful to others contemplating the delivery of a distributed program that includes a full medical program in a remote area. These include: 1. Leadership at the highest levels of the university is crucial. 2. Expect faculty turnover and avoid single person vulnerabilities. 3. Actively engage local clinicians. 4. Ensure a strong focus on new or alternative selection processes that are able to predict progression. 5. Provide preparatory skills and support for students, especially Indigenous students, with non-science backgrounds. 6. Appreciate and accommodate the community and family pressures experienced by some Indigenous students. 7. Anticipate that the first pioneering cohort of students will not be typical of future cohorts, and work with them to adapt the curriculum, teaching and selection methods. 8. Whilst exemplary telecommunications are needed, some elements of the curriculum will be able to be delivered far better locally than at the larger campus. 9. Do not underestimate the level of student and staff support required both locally and centrally. Develop a 'network' rather than a 'hub and spoke' model. 10. The network may include multiple dispersed placement sites, requiring infrastructure, staffing and ongoing support. 11. The 'new kid' will mean the 'older sibling' will change for the better and use the small size and agility to explore innovations. 12. Focus on the goals. We wanted to contribute to improved economic, social and health outcomes for NT residents by developing an appropriately prepared medical workforce, thereby eliminating the need to recruit doctors from interstate and overseas, and by graduating more Indigenous doctors - potential medical leaders for Australia. 13. Build your expectation for success based on past successes in innovation. Flinders University was able to build on its experience in developing the first 4-year medical program in Australia.

BackgroundSeasonal influenza A infection affects a significant cohort of the global population annually, resulting in considerable morbidity and mortality. Therapeutic strategies are of limited efficacy, and during a pandemic outbreak would only be available to a minority of the global population. Over-the-counter medicines are routinely taken by individuals suffering from influenza, but few studies have been conducted to determine their effectiveness in reducing pulmonary immunopathology or the influence they exert upon the generation of protective immunity.MethodsA mouse model of influenza infection was utilised to assess the efficacy of paracetamol (acetaminophen) in reducing influenza-induced pathology and to examine whether paracetamol affects generation of protective immunity.ResultsAdministration (intraperitoneal) of paracetamol significantly decreased the infiltration of inflammatory cells into the airway spaces, reduced pulmonary immunopathology associated with acute infection and improved the overall lung function of mice, without adversely affecting the induction of virus-specific adaptive responses. Mice treated with paracetamol exhibited an ability to resist a second infection with heterologous virus comparable with that of untreated mice.ConclusionsOur results demonstrate that paracetamol dramatically reduces the morbidity associated with influenza but does not compromise the development of adaptive immune responses. Overall, these data support the utility of paracetamol for reducing the clinical symptoms associated with influenza virus infection.
