Radiation therapy could increase the risk of heart disease in young women According to research published in JACC: CardioOncology, women with left‐sided breast cancer undergoing radiation therapy between 1985 and 2008 had over twice the risk of subsequent coronary artery disease compared with women with right‐sided breast cancer with a median of 14 years of follow‐up. Researchers studied participants in the Women’s Environmental Cancer and Radiation Epidemiology Study to evaluate the risk of coronary artery disease in breast cancer survivors. After excluding women who did not receive radiation therapy or who had a pre‐existing cardiovascular disease diagnosis, 972 women were eligible for analysis. All the participants were diagnosed with breast cancer between 1985 and 2008, were under 55 years of age, and had completed a cardiovascular health questionnaire. Clinical and lifestyle factors were distributed equally among both groups of women. Previous studies in older populations have shown left‐sided radiation therapy is associated with increased risk of developing heart disease, although the level of risk varied between studies. In the present study, although participants had equal event‐free survival of coronary artery disease for 5 years, regardless of breast cancer laterality, event‐free survival was lower among women treated with left‐sided radiation therapy at each subsequent 5‐year mark. In addition, 91% of coronary artery disease diagnoses occurred more than 5 years after radiation therapy, demonstrating the need for long term follow‐up in younger breast cancer survivors, according to the researchers. Overall, the 27.5‐year cumulative incidence of coronary artery disease for women who received left‐sided radiation therapy was 10.5% compared with 5.8% for women who underwent right‐sided radiation therapy. For women diagnosed between ages 25 and 39 years, those who received left‐sided radiation therapy had a 5.9% incidence of coronary artery disease, while those receiving right‐sided radiation therapy reported no coronary artery disease. Women who were diagnosed between ages 40 and 54 years experienced an 18.7% incidence of coronary artery disease after undergoing left‐sided radiation therapy, and 6.8% after undergoing right‐sided radiation therapy. https://www.sciencedirect.com/science/article/pii/S2666087321001629?via%3Dihub Common antibiotic reduces low birth weight and prematurity A common antibiotic has been found to reduce low birth weight and premature births, if taken during pregnancy, in countries where malaria is endemic, according to a meta‐analysis, led by the University of Melbourne and the Murdoch Children’s Research Institute and published in EClinicalMedicine. The analysis found that azithromycin reduced low birth weight and prematurity in Africa and Asia but did not reduce infant deaths, infections or hospital admissions. The researchers reviewed 14 studies undertaken in African and Asian countries, involving 17 594 participants. Azithromycin is an inexpensive antibiotic widely used to treat chest and ear infections. In pregnancy, it has been specifically used to treat sexually transmitted infections and, alongside other antimalarial drugs, to prevent adverse consequences of malaria on maternal and fetal outcomes and caesarean wound infections. The authors wrote that it was unclear whether azithromycin would improve perinatal and neonatal outcomes in non‐malaria endemic settings, and the potential effect on stillbirth rates needed further investigation. Globally, infections cause about 21% of 2.4 million neonatal deaths each year and 52% of all deaths under 5 years, with a disproportionate amount occurring in low and middle income countries. Infections are also common in mothers, with about 5 million cases of pregnancy‐related infections occurring each year, resulting in 75 000 maternal deaths. https://www.thelancet.com/journals/eclinm/article/PIIS2589-5370(21)00403-X/fulltext

Self‐collection cervical screening in the renewed National Cervical Screening Program: a qualitative study

Objectives: To evaluate the implementation and acceptability of the self‐collection cervical screening pathway since commencement of the renewed National Cervical Screening Program (rNCSP), from the perspectives of screening participants and primary care practitioners. Design, setting, participants: Qualitative study; individual semi‐structured interviews with 45 screening participants and 18 primary care practitioners in Victoria who had engaged with the self‐collection pathway during the first 17 months of the rNCSP (1 December 2017 ‒ 30 April 2019). Results: The self‐collection pathway was highly acceptable as an alternative cervical screening pathway for most participating screening participants and practitioners. Some screening participants indicated that they would not have been screened had the pathway not been available. Acceptability was lower among those who had tested positive for HPV types not 16/18, a result that requires additional testing of a clinician‐collected cervical sample. Use of the self‐collection pathway is driven more by practitioners than their patients. Interpretations of the self‐collection guidelines varied between practices. Barriers to expanding promotion of the pathway by practitioners included difficulties with identifying eligible participants. Conclusions: Increasing the accessibility of the self‐collection pathway to under‐ and never screened women could reduce inequities in cervical cancer outcomes for those not participating in the main screening pathway. Practitioners should be provided resources to integrate self‐collection into routine practice and to efficiently implement the entire self‐collection pathway, in order to maximise its use and to optimise the experience for screening participants.

Who is speaking for us? Identifying Aboriginal and Torres Strait Islander scholarship in health research

To the Editor: Australia is home to the oldest continuing cultures on Earth. Yet, rather than being treasured as a source of national pride, Aboriginal and Torres Strait Islander knowledges remain mostly unappreciated and, at times, actively silenced (eg, Uluru Statement).1 Passed down through generations, these valuable, continually changing knowledge systems are core to our adaptability, strength and survival against extreme adversity including colonisation. Persistent health disparities between Indigenous and other Australians signal the ineffectiveness of allegedly well intentioned policy and research that have largely produced deficit‐focused research, describing the extent of the Aboriginal and Torres Strait Islander problem rather than being driven by the priorities and solutions of Aboriginal and Torres Strait Islander communities. Institutions are now acknowledging that to close the gap in health disparities, “Aboriginal and Torres Strait Islander people must determine, drive and own the desired outcomes”.2 Gradual transformation in research governance and methodologies has occurred through ethics protocols and quality appraisal tools3 guiding the positioning of Aboriginal and Torres Strait Islander people as leaders and drivers of strengths‐based, benefit‐led research processes.4 Aboriginal and Torres Strait Islander researchers are more often leading the way in key health system domains, such as research ethics, education and effective community‐based research, but there is currently no systematic way of identifying our scholarship in the peer‐reviewed literature. How do we, as Aboriginal and Torres Strait Islander people, know who is representing, and speaking for, us? We assert the need to develop strategies to rectify and improve transparency of Indigenous health research. The first steps could be: inclusion of searchable tags for Indigenous authorship and contributorship (acknowledging non‐written contributions); for example, through extension of the Contributor Roles Taxonomy (CRediT), which is integrated into the Open Researcher and Contributor ID (ORCID; www.orcid.org) and used in over 120 journals;5 and expansion of contributor statements outlining diversity of roles and the positionality of our non‐Indigenous allies within the research. This would enhance the ability to efficiently distinguish Aboriginal and Torres Strait Islander scholarship, increasing the visibility of our knowledges and perspectives in research and translation, thereby improving the transparency of academic literature to guide decisions about our health and wellbeing. We seek the MJA’s leadership in “foregrounding Indigenous sovereignty”6 by advocating and appropriately acknowledging our contribution in health research.

Non‐invasive prenatal testing: clinical utility and ethical concerns about recent advances

To the Editor: Thomas and colleagues1 describe the ethical complexities that can arise in the use of non‐invasive prenatal testing (NIPT) based on the detection of cell‐free fetal DNA in the maternal circulation to screen for chromosomal and other genetic fetal conditions, especially if the clinical utility and implications of the testing are not well understood and explained. They indicate that “the current NIPT tests available are for specific chromosomal aneuploidy, extended panels of targeted conditions and low resolution whole genome sequencing”. We support that all tests (for screening or diagnosis, and not just genetic tests) should be explained. However, we remind readers that there are specific tests using NIPT of cell‐free fetal DNA that have strong potential to benefit women and their fetuses and are at very low risk of the ethical hazards that concern Thomas and colleagues. A lead example is testing in women who are RhD (antigen) negative to predict whether the fetus is RHD (genotype) positive. Such testing can establish with a high level of certainty whether the fetus is RHD negative, in which case the woman can be spared the need for antenatal RhD immunoprophylaxis to prevent alloimmunisation. This approach not only spares around a third of women who are RhD‐negative the need for immunoprophylaxis but may also help reduce the burden on a small and altruistic pool of RhD immunoglobulin donors.2,3 In RhD‐negative women with preformed RhD antibodies, similar testing can be used to determine whether or not there is a need for intensive surveillance during the pregnancy for haemolytic disease of the fetus and newborn. To consider all tests that use NIPT based on cell‐free fetal DNA as carrying the same complexity of explanation and ethical risk would resemble a conclusion that all immunochemistry is ethically risky because of the difficulties of explaining and interpreting prostate‐specific antigen tests, or that all fetal ultrasound is unethical because in some countries it is used inappropriately for sex selection. We encourage readers to consider that the underlying reason and specific target for each test, much more than the platform on which it is run, determines the level of ethical complexity.

Non‐invasive prenatal testing: clinical utility and ethical concerns about recent advances

To the Editor: The scope of genetic testing has advanced exponentially in the past 5–10 years and conversations between patients and clinicians are becoming more nuanced. This highlights the value of genetic professionals who are skilled at ensuring patients’ understanding of genetic testing to satisfy the legal requirements for consent.1,2 Other complexities in the setting of prenatal testing include finding of variants of uncertain significance, variable penetrance or expressivity associated with most genetic conditions, and potential future treatments for adult‐onset conditions uncovered by testing. Thomas and colleagues3 referred to power imbalance between a doctor and a patient as a factor that could ethically undermine consent for non‐invasive prenatal screening (NIPS). However, this power imbalance exists across all facets of medicine. Patients today are more medically savvy owing to easy access to information technology, thus reducing the knowledge gap (and the power imbalance). A doctor’s duty of care is to provide accurate and appropriate information that is understood by the patient in order to make a valid consent.2 There is no alternative to a valid consent for NIPS than one that is built upon an “I and thou” doctor–patient relationship.4 This relationship is a dynamic and shared experience, focusing not on the knowledge but on supporting expectant parents in making value‐consistent decisions.5 Uncertainties are not unique to NIPS; perinatal uncertainties are not new to either genetics or medicine, which can arise when a diagnosis is not made as well as when a diagnosis is made. Another ethical concern regarding NIPS is access and equity. As there is no Medicare funding for NIPS, should genetic disorders be screened out by the rich, would genetic conditions become the disease of the poor? This has implications for the society as a whole. Is there a duty to have a healthy child versus should we value diversity and disability? Would there be less social or medical support should society become less tolerant of individuals with disability? Genetics and other areas of medicine are evolving rapidly; nevertheless, the shared ethical considerations, including valid consent, uncertainty, and access equity, have remained to shape the moral principles of our society in this genomics era.
