    Misgendering negatively affects the mental and physical health of trans individuals

    Misgendering occurs when a person is addressed or described using language that does not match their gender identity. Misgendering within the health care system can significantly affect the mental and physical health of transgender (hereafter trans) individuals and can negatively impact future engagement with the health care system. Systemic policies and practices create situations which increase the likelihood of misgendering and experience of stigma, affecting the delivery of health care to trans individuals.

      More nuanced health advice is needed to protect populations and individuals from exposure to bushfire smoke

      Bushfires have always been a feature of the natural environment in Australia, but the risk has increased over time as fire seasons start earlier, finish later, and extreme fire weather (ie, very hot, dry and windy conditions that make fires fast moving and very difficult to control) becomes more severe with climate change.,, The 2019–20 bushfires in Australia, particularly in New South Wales, Victoria, Queensland and the Australian Capital Territory, have caused at least 33 fatalities, extensive damage to property and destruction of flora and fauna, and have exposed millions of people to extreme levels of air pollution. Bushfire smoke, as well as smoke from prescribed burns, contains a complex mixture of particles and gases that are chemically transformed in the atmosphere and transported by the wind over long distances. In this context, a major public health concern is population exposure to atmospheric particulate matter (PM) with a diameter < 2.5 μm (PM2.5), which can penetrate deep into the respiratory system, inducing oxidative stress and inflammation, and even translocate into the bloodstream.

        Advances in type 2 diabetes therapy: a focus on cardiovascular and renal outcomes

        Renata Libianto, Timothy ME Davis and Elif I Ekinci

        Summary

        • Treatment options for type 2 diabetes have expanded. While metformin remains the first line treatment in most cases, choices for second line treatment now extend beyond sulfonylureas and include the sodium–glucose cotransporter 2 (SGLT2) inhibitors, glucagon‐like peptide 1 (GLP1) receptor agonists, and dipeptidyl peptidase 4 (DPP4) inhibitors.
        • SGLT2 inhibitors are recommended for people with atherosclerotic cardiovascular disease, heart failure or kidney disease. Diabetic ketoacidosis is an uncommon but important side effect; its occurrence can be minimised with appropriate patient education and management, especially during perioperative periods and times of illness.
        • GLP1 receptor agonists are recommended for people with atherosclerotic cardiovascular disease. Gastrointestinal side effects are common but are less prominent with the longer acting agents and can be minimised with slow titration of the shorter acting agents.
        • DPP4 inhibitors are generally well tolerated, but alogliptin and saxagliptin should be used with caution in people with risk factors for heart failure.
        • To optimise the management of type 2 diabetes, clinicians need to be aware of the pharmacological characteristics of each class of blood glucose‐lowering medications and of the effect on cardiovascular health and renal function, balanced by potential adverse effects.
        • Medications that have cardiovascular or renal benefits should be prescribed for patients with these comorbidities, and this is reflected in recent international guidelines.

          Abstract

          Objectives: To determine the incidence of self‐reported non‐coeliac wheat sensitivity (SR‐NCWS) and factors associated with its onset and resolution; to describe the prevalence of factors associated with gluten avoidance.

          Design: Longitudinal cohort study; analysis of responses to self‐administered validated questionnaires (Digestive Health and Wellbeing surveys, 2015 and 2018).

          Setting, participants: Subset of an adult population sample randomly selected in 2015 from the electoral rolls for the Newcastle and Gosford regions of New South Wales.

          Main outcome measures: Prevalence of SR‐NCWS (2015, 2018) and incidence and resolution of SR‐NCWS, each by demographic and medical factors; prevalence of gluten avoidance and reasons for gluten avoidance (2018).

          Results: 1322 of 2185 eligible participants completed the 2018 survey (response rate, 60.5%). The prevalence of SR‐NCWS was similar in 2015 (13.8%; 95% CI, 12.0–15.8%) and 2018 (13.9%; 95% CI, 12.1–15.9%); 69 of 1301 respondents (5.3%) reported developing new onset (incident) SR‐NCWS between 2015 and 2018 (incidence, 1.8% per year). Incident SR‐NCWS was significantly associated with a diagnosis of functional dyspepsia, and negatively associated with being male or older. Gluten avoidance was reported in 2018 by 24.2% of respondents (20.5% partial, 3.8% complete avoidance); general health was the most frequent reason for avoidance (168 of 316 avoiders, 53%). All 13 participants with coeliac disease, 56 of 138 with irritable bowel syndrome (41%), and 69 of 237 with functional dyspepsia (29%) avoided dietary gluten.

          Conclusions: The prevalence of SR‐NCWS was similar in 2015 and 2018. Baseline (2015) and incident SR‐NCWS (2018) were each associated with functional gastrointestinal disorders. The number of people avoiding dietary gluten exceeds that of people with coeliac disease or SR‐NCWS, and general health considerations and abdominal symptoms are the most frequently reported reasons for avoidance.

            Abstract

            Objectives: To describe changes in childhood cancer incidence in Australia, 1983–2015, and to estimate projected incidence to 2035.

            Design, setting: Population‐based study; analysis of Australian Childhood Cancer Registry data for the 20 547 children under 15 years of age diagnosed with cancer in Australia between 1983 and 2015.

            Main outcome measures: Incidence rate changes during 1983–2015 were assessed by joinpoint regression, with rates age‐standardised to the 2001 Australian standard population. Incidence projections to 2035 were estimated by age‐period‐cohort modelling.

            Results: The overall age‐standardised incidence rate of childhood cancer increased by 34% between 1983 and 2015, increasing by 1.2% (95% CI, +0.5% to +1.9%) per annum between 2005 and 2015. During 2011–2015, the mean annual number of children diagnosed with cancer in Australia was 770, an incidence rate of 174 cases (95% CI, 169–180 cases) per million children per year. The incidence of hepatoblastoma (annual percentage change [APC], +2.3%; 95% CI, +0.8% to +3.8%), Burkitt lymphoma (APC, +1.6%; 95% CI, +0.4% to +2.8%), osteosarcoma (APC, +1.1%; 95%, +0.0% to +2.3%), intracranial and intraspinal embryonal tumours (APC, +0.9%; 95% CI, +0.4% to +1.5%), and lymphoid leukaemia (APC, +0.5%; 95% CI, +0.2% to +0.8%) increased significantly across the period 1983–2015. The incidence rate of childhood melanoma fell sharply between 1996 and 2015 (APC, –7.7%; 95% CI, –10% to –4.8%). The overall annual cancer incidence rate is conservatively projected to rise to about 186 cases (95% CI, 175–197 cases) per million children by 2035 (1060 cases per year).

            Conclusions: The incidence rates of several childhood cancer types steadily increased during 1983–2015. Although the reasons for these rises are largely unknown, our findings provide a foundation for health service planning for meeting the needs of children who will be diagnosed with cancer until 2035.

              Implementing value‐based health care at scale: the NSW experience

              Elizabeth Koff and Nigel Lyons
              Med J Aust 2020; 212 (3): . || doi: 10.5694/mja2.50470
              Published online: 17 February 2020

              What is value in health care and how can the system deliver it at scale?

              The New South Wales health system exemplifies the worldwide challenge of health service sustainability. With 234 public hospitals and facilities employing over 130 000 staff, the system provides universal access to health care for a growing population of almost 8 million people across a diverse geography of over 800 000 km2. The NSW Health budget in 2018–19 was $25 billion, representing over 25% of the annual state budget. As with all health systems, NSW Health is experiencing growing pressure from chronic disease, an ageing population and the use of new technology. In response, optimising health system access and efficiency has been central to health reform in NSW.

                First statewide meningococcal B vaccine program in infants, children and adolescents: evidence for implementation in South Australia

                Helen S Marshall, Noel Lally, Louise Flood and Paddy Phillips
                Med J Aust 2020; 212 (2): . || doi: 10.5694/mja2.50481
                Published online: 3 February 2020

                Summary

                • Invasive meningococcal disease (IMD) is an uncommon but life‐threatening infection caused by Neisseria meningitidis. Serogroups B, C, W and Y cause most IMD cases in Australia. The highest incidence occurs in children under 5 years of age. A second peak occurs in adolescents and young adults, which is also the age of highest carriage prevalence of N. meningitidis.
                • Meningococcal serogroup B (MenB) disease predominated nationally before 2016 and has remained the predominant cause of IMD in South Australia with 82% of cases, compared with 35% in New South Wales, 35% in Queensland, 9% in Victoria, 29% in Western Australia and 36% nationally in 2016.
                • MenB vaccination is recommended by the Australian Technical Advisory Group on Immunisation for infants up to 2 years of age and adolescents aged 15–19 years (age 15–24 years for at‐risk groups, such as people living in close quarters or smokers), laboratory workers with exposure to N. meningitidis, and Aboriginal and Torres Strait Islander children from age 2 months to 19 years.
                • Due to the epidemiology and disease burden from MenB, a meningococcal B vaccine program has been implemented in South Australia for individuals with age‐specific incidence rates higher than the mean rate of 2.8/100 000 population in South Australia in the period 2000–2017, including infants, young children (< 4 years) and adolescents (15–20 years).
                • Program evaluation of vaccine effectiveness against IMD is important. As observational evidence also suggests 4CMenB may have an impact on Neisseria gonorrhoeae with genetic homology between bacterial species, the vaccine impact on gonorrhoea will also be assessed.

                  Caesarean section births for twins: rational choice, or a non‐evidence‐based intervention that may cause harm?

                  The change from vaginal births to operative births may entail unforeseen longer term consequences

                  The benefits and risks of birth by caesarean section are debated, with passionate proponents on each side of the discussion. The most recent national data (for 2017) indicate that in Australia more than one‐third of babies (35%) were born after caesarean section. While its safety has undoubtedly improved, it is still reported that greater maternal and perinatal morbidity and mortality are associated with caesarean section than with vaginal births. The longer term health outcomes for mother and child are also important. In this issue of the MJA, Liu and her colleagues report that the caesarean rate for twin pregnancies in Victoria has almost tripled over the past three decades, and that the most frequent reason for operative intervention was the twin pregnancy itself. It is pertinent to examine the reasons for this trend and to ask whether it is justified.

                    The cheques and balances of national universal screening of patients with new colorectal cancer for Lynch syndrome

                    Megan Hitchins

                    Tiered universal screening systems that save lives are cost‐effective

                    About 15–20% of colorectal cancers exhibit microsatellite instability (MSI) caused by deficient DNA mismatch repair (MMR). Most of these cancers (80%) are sporadic, associated with hypermethylation of the MLH1 gene promoter. Lynch syndrome is caused by germline mutations affecting one of the MMR genes (MLH1, MSH2, MSH6, PMS2), and accounts for 15–20% of MMR‐deficient (dMMR) colorectal cancers, or 2–5% of all colorectal cancers, making it the most common hereditary colorectal cancer predisposition syndrome. People with Lynch syndrome are at increased risk of several cancer types, especially colorectal cancer: the risk by age 70 years is 10–82%, depending on the mutant gene, considerably higher than that of the general population (4.5%).

                      A 59‐year‐old woman attended our spasticity clinic with treatment‐resistant atypical pressure ulcer in the right hand caused by focal spasticity secondary to upper motor neuron lesion. She had suffered subarachnoid haemorrhage from a ruptured arteriovenous malformation and underwent craniotomy. She was deemed not suitable for structured rehabilitation due to her significant disability and was placed in a residential accommodation. The patient was using an electrical wheelchair and was requiring full assistance with her personal care. She had typical, dense post‐stroke right‐sided spastic hemiplegia. In the upper limb, she had shoulder adduction and internal rotation, elbow flexion, wrist palmar flexion with flexed fingers at the metacarpophalangeal and proximal interphalangeal joints. She had a baclofen pump that controlled her lower limb spasticity.
