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. ⋯ 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.

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. ⋯ 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.

To investigate the incidence of second primary cancers in people diagnosed with cancer during childhood. ⋯ Survivors of childhood cancer remain at increased risk of a second primary cancer well into adulthood. As the late effects of cancer treatment probably contribute to this risk, treatments need to be refined and their toxicity reduced, without reducing their benefit for survival.
