"I want to see them thrive!": exploring health service research priorities for young Aboriginal children growing up in Alice Springs - a qualitative study.

To better understand the specific influences of early life on the long-term health and well-being of local Aboriginal children in Alice Springs, high-quality local longitudinal data is required. The Central Australian Aboriginal Congress and the Murdoch Children's Research Institute are exploring the feasibility of establishing a cohort study to fill this gap. A nested qualitative study was conducted to identify priority issues that can be translated into research questions answerable through the proposed cohort study. Semi-structured interviews and focus group discussions (FGDs) were conducted with a range of key community stakeholders, parents and caregivers of young Aboriginal children from Alice Springs in the Northern Territory between 2020 and 2021. Two Aboriginal and two non-Aboriginal researchers conducted 27 interviews and 3 FGDs with 42 participants. Three broad themes were constructed through reflexive thematic analysis representing the areas of focus community stakeholders and parents want future research to prioritise: (1) social determinants of health (2) building positive connections, and (3) making sure kids grow up strong and healthy. Priority setting for future research should be driven by Aboriginal and Torres Strait Islander peoples in order to be of practical benefit to their community. This qualitative study found that housing, transport and positive connections through nurturing and engaged parents were some of the most important issues raised. Participants also wanted future research to focus on issues specific to children such as nutrition, hearing loss, language development and capacity to learn. These findings will guide future work led by local Aboriginal researchers to co-design the proposed cohort study.

Focused, low tube potential, coronary calcium assessment prior to coronary CT angiography: A prospective, randomized clinical trial.

BACKGROUND: Coronary artery calcium (CAC) scanning is commonly performed before coronary CT angiography (CTA) based partly on its potential to influence CTA scan parameters. Encompassing the whole heart and performed at high tube potential (120 â€‹kVp), standard (Agatston) CAC scanning adds to patient radiation exposure. Most CAC exists in the proximal and mid coronary segments and is easily visualized at low kVp. METHODS: We tested the impact of a modified calcium scan on coronary CTA acquisition decision-making and image quality in a randomized clinical trial. Providers documented planned CTA acquisition parameters prior to CAC scanning in a blinded manner. Standard Agatston CAC scans proceeded in typical fashion whereas modified scans utilized 80 â€‹kVp and reduced z-axis length focused on the proximal-to-mid coronary arteries. CTA providers reviewed the CAC burden then documented final acquisition parameters. RESULTS: The study included 172 patients (48% female; mean age 59 â€‹± â€‹6.7). As planned, the calcium scan effective dose was significantly lower in the modified CAC scan group (0.14 vs. 0.74 â€‹mSv using a 0.014 k-factor or 0.26 vs. 1.38 â€‹mSv using a 0.026 k-factor; both p â€‹< â€‹0.001). Initially selected CTA parameters were changed at an identical rate following visual CAC assessment (59%). There was no significant difference in coronary CTA image quality (median quality score â€‹= â€‹4 in both groups, p â€‹= â€‹0.26), noise (31.0 vs 31.4 HU; p â€‹= â€‹0.81), or signal/noise ratio (17.9 vs 16.8; p â€‹= â€‹0.26). CONCLUSIONS: A low-kVp scan with focused field-of-view provides actionable information regarding the presence and severity of CAC prior to coronary CTA. Coronary CTA parameters based on patient variables are frequently modified after assessing CAC burden in the CTA suite. CLINICALTRIALS. GOV REGISTRATION NUMBER: NCT02972242.
