“…One prospective cohort study found that hearing loss was frequent in young Aboriginal children in a semi‐arid zone of Western Australia, 3 but its prevalence in Aboriginal infants in urban areas has not been investigated 4 . We therefore estimated the prevalence of hearing loss in Aboriginal infants in Perth, Western Australia, enrolled in the Djaalinj Waakinj cohort study (2017–2021), 5 and examined the association between otitis media and hearing responses.…”

titis media and associated hearing loss are highly prevalent in Indigenous Australian children. 1 Most relevant prevalence studies have been undertaken in rural and remote regions, although most Indigenous children live in urban areas. 2 One prospective cohort study found that hearing loss was frequent in young Aboriginal children in a semi-arid zone of Western Australia, 3 but its prevalence in Aboriginal infants in urban areas has not been investigated. 4 We therefore estimated the prevalence of hearing loss in Aboriginal infants in Perth, Western Australia, enrolled in the Djaalinj Waakinj cohort study (2017-2021), 5 and examined the association between otitis media and hearing responses.

“…The focus on children living in remote areas was based on the assumption that children from remote communities have more severe disease than those in urban areas. However, it has been shown recently that Australian Aboriginal children from urban areas in Western Australia have similar rates of OM as those reported for remote communities ( Swift et al., 2020 ); suggesting that environmental risk factors alone may not lead to increased susceptibility of Australian Aboriginal children to OM. This is supported by our data showing similar IgG titres for 3/4 NTHi antigens, with similar quality, being observed between locations.…”

“…In Aboriginal children, OM starts earlier, is more prolonged, and more severe than in non-Aboriginal Australian children ( Williams and Jacobs, 2009 ; Williams et al., 2009 ). Most data on OM prevalence in Aboriginal children has been reported from those living in remote and rural areas ( Leach et al., 1994 ; Morris et al., 2005 ; Leach and Morris, 2007 ; Wenxing et al., 2012 ; Leach et al., 2016 ) however, a recent Western Australian study has shown that urban Aboriginal children also experience disproportionality high rates of OM, with over 50% of 6 month old children suffering from OM ( Swift et al., 2020 ). Nasopharyngeal carriage of otopathogens is a prerequisite for development of bacterial OM ( Wenxing et al., 2012 ).…”

Australian Aboriginal Otitis-Prone Children Produce High-Quality Serum IgG to Putative Nontypeable Haemophilus influenzae Vaccine Antigens at Lower Titres Compared to Non-Aboriginal Children

BackgroundNontypeable Haemophilus influenzae (NTHi) is the most common bacterial otopathogen associated with otitis media (OM). NTHi persists in biofilms within the middle ears of children with chronic and recurrent OM. Australian Aboriginal children suffer exceptionally high rates of chronic and recurrent OM compared to non-Aboriginal children. NTHi protein vaccines comprised of antigens associated with both adhesion and persistence in a biofilm are under development and could be beneficial for children with chronic and recurrent OM. Understanding the ontogeny of natural antibody development to these antigens provides insight into the value of vaccinating with particular antigens.MethodsAn in-house multiplex fluorescent bead immunoassay was used to measure serum IgG titres and avidity for three putative vaccine antigens: recombinant soluble PilA (rsPilA), ChimV4, and outer membrane protein 26 (OMP26) in sera from Australian Aboriginal otitis-prone children (n=77), non-Aboriginal otitis-prone children (n=70) and non-otitis-prone children (n=36). Serum IgG titres were adjusted for age, and geometric mean concentrations (GMCs) were compared between groups using a univariate analysis model. Antibody avidity was calculated as a relative avidity index and compared between groups using ANOVA.ResultsAustralian Aboriginal otitis-prone children had lower serum IgG titres to rsPilA and ChimV4 than non-Aboriginal otitis-prone children (p<0.001), and non-otitis-prone children (p<0.020). No differences were observed between serum IgG titres from non-Aboriginal otitis-prone children and non-otitis-prone children. There were also no differences in the proportion of high avidity IgG specific for these antigens between these groups. Serum IgG titres to OMP26 were similar between all groups (p>0.670) although otitis-prone children had a higher proportion of high avidity antibodies to this antigen.ConclusionsAustralian Aboriginal otitis-prone children had lower serum IgG titres to 2/3 major NTHi vaccine candidate antigens, suggesting these children are unable to develop persistent IgG responses due to repeated NTHi exposure. These reduced IgG titres may relate to earlier and more frequent exposure to diverse NTHi strains in Aboriginal children through carriage or infection. These data suggest that Aboriginal children may benefit from immunisation with vaccines containing these antigens to increase titres of protective antibodies.

“…For frontline health professionals, bridging world views requires practice change through governance that encourages intersectionality, for example intercultural governance (Brigg and Curth-Bibb 2017) or cultural governance (Swift et al 2020). This includes reflecting on the governance domains of processes, relationship, institutions and structures (Hunt et al 2008); their overlay with intersectional themes (Fig.…”

The objective of this scoping review was to map the current practice and best evidence for embedding cultural safety in child protection responses for Aboriginal families in hospitals. Electronic databases were searched systematically and the reference lists examined. Efforts to reduce the risk of bias were made including using an inductive approach. Eight research papers were included following the exclusion of 25 papers for the final analysis. Three main themes in relation to what is necessary to embed cultural safety for Aboriginal families when child protection responses are raised in hospital were found. These were (a) relationships, (b) organisational processes and (c) culture. The analysis underscores the need for development of child protection strategies that focus on cultural safety rather than cultural competence alone. This provides some direction for policy and practice development in this field, and has also highlighted the deficiencies in evidence and urgent need for further research.
