Purpose: Families of children in pediatric acute care offered ultra-rapid genomic sequencing are making complex decisions in a high stress period. To reduce complexity for families and clinicians, we offered genomic screening for the child and parents after completion of diagnostic testing. We evaluated uptake, understanding and service delivery preferences., Methods: A cohort of 235 families who had completed ultra-rapid diagnostic genomic sequencing at 17 Australian hospitals were offered up to three screens on their genomic data: pediatric-onset, adult-onset, expanded couple carrier screening. We investigated decision-making, understanding and service delivery preferences using surveys at three timepoints (pre-counseling, post-counseling, post-result) and performed inductive content analysis of pre-test genetic counseling transcripts., Results: 119 families (51%) attended genetic counseling with 115 (49%) accepting genomic screening. Survey respondents were more likely to find decisions about couple carrier screening 'easy' (87%) than adult (68%; p=0.002) or pediatric (71%; p=0.01) screening decisions. All respondents with newly detected pathogenic variants accurately recalled this one month later. A delayed offer of screening was acceptable to most respondents (78%)., Conclusion: Separating genomic screening from the stressful diagnostic period is supported by families who demonstrate good knowledge and recall. Our results suggest delaying genomic screening should be trialed more widely., (Copyright © 2024. Published by Elsevier Inc.)

Purpose: To develop and evaluate a scalable national program to build confidence, competence and capability in the use of rapid genomic testing (rGT) in the acute pediatric setting., Methods: We used theory-informed approaches to design a modular, adaptive program of blended learning aimed at diverse professional groups involved in acute pediatric care. The program comprised 4 online learning modules and an online workshop and was centered on case-based learning. We evaluated the program using the Kirkpatrick 4-level model of training evaluation and report our findings using the Reporting Item Standards for Education and its Evaluation (RISE2) guidelines for genomics education and evaluation., Results: Two hundred and two participants engaged with at least 1 component of the program. Participants self-reported increased confidence in using rGT, (P < .001), and quiz responses objectively demonstrated increased competence (eg, correct responses to a question on pretest counseling increased from 30% to 64%; P < .001). Additionally, their capability in applying genomic principles to simulated clinical cases increased (P < .001), as did their desire to take on more responsibility for performing rGT. The clinical interpretation of more complex test results (such as negative results or variants of uncertain significance) appeared to be more challenging, indicating a need for targeted education in this area., Conclusion: The program format was effective in delivering multidisciplinary and wide-scale genomics education in the acute care context. The modular approach we have developed now lends itself to application in other medical specialties or areas of health care., Competing Interests: Conflict of Interest The authors declare no conflicts of interest., (Copyright © 2024 The Authors.

Introduction: Primarily used as ultrasound contrast agents, microbubbles have recently emerged as a versatile therapeutic vector that can be 'burst' to deliver payloads in the presence of suitably optimised ultrasound fields. Ultrasound-stimulated microbubbles (USMB) have recently demonstrated improvements in treatment outcomes across a variety of clinical applications. This scoping review investigates whether this potential translates into the context of radiation therapy by evaluating the application of this technology across all three phases of radiation action., Methods: Primary research articles, excluding poster presentations and conference proceedings, were identified through systematic searches of the PubMed NCBI/Medline, Embase/OVID, Web of Science and CINAHL/EBSCOhost databases, with additional articles identified via manual Google Scholar searching. Articles were dual screened for inclusion using the Covidence systematic review platform and classified against all three phases of radiation action., Results: Overall, 57 eligible publications from a total of 1389 identified articles were included in the review, with studies dating back to 2012. Study heterogeneity prevented formal statistical analysis; however, most articles reported improved outcomes using USMB in the presence of radiation compared to that of radiation alone. These improvements appear to result from the use of USMB as either a biovascular disruptor causing tumour cell damage via indirect mechanisms, or as a localised treatment vector that directly increases tumour cell uptake of other therapeutic and physical agents designed to enhance radiation action., Conclusions: USMB demonstrate exciting potential to enhance the effects of radiation treatments due to their versatility and capacity to target all three phases of radiation action., (© 2024 The Author(s).

Purpose: This study aims to investigate the radiation enhancement effects of ultrasound-stimulated microbubbles (USMB) with X-rays and nanoparticles on pancreatic cancer cells in vitro ., Methods: Sonazoid™ microbubbles were used for USMB treatment with a commercially available ultrasound unit. The characterization of the microbubbles before and after ultrasound exposure with different mechanical parameters was evaluated microscopically. Two pancreatic cancer cell lines, MIAPaCa-2 and PANC-1, were treated with different concentrations of microbubbles in combination with 150 kVp X-rays and hydrogen peroxide-modified titanium dioxide nanoparticles. Cell viability was evaluated using a water-soluble tetrazolium dye and a colony formation assay. In addition, intracellular reactive oxygen species (ROS) induced by the combined treatment were assessed., Results: The number of burst microbubbles increased with ultrasound's higher mechanical index and the exposure time. A significant radiation enhancement effect with a significant increase in ROS levels was observed in MIAPaCa-2 cells treated with USMB and 6 Gy X-rays, whereas it was not significant in PANC-1 cells treated with the same. When a higher concentration of USMB was applied with X-rays, no radiation enhancement effects were observed in either cell line. Moreover, there was no radiation enhancement effect by USMB between cells treated with and without nanoparticles., Conclusions: The results indicate that USMB treatment can additively enhance the therapeutic efficacy of radiation therapy on pancreatic cancer cells, while the synergistic enhancement effects are likely to be cell type and microbubble concentration dependent. In addition, USMB did not improve the efficacy of nanoparticle-induced radiosensitization in the current setting., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Journal of Medical Physics.)

Introduction: As routine genomic testing expands, so too does the opportunity to look for additional health information unrelated to the original reason for testing, termed additional findings (AF). Analysis for many different types of AF may be available, particularly to families undergoing trio genomic testing. The optimal model for service delivery remains to be determined, especially when the original test occurs in the acute care setting., Methods and Analysis: Families enrolled in a national study providing ultrarapid genomic testing to critically ill children will be offered analysis for three types of AF on their stored genomic data: paediatric-onset conditions in the child, adult-onset conditions in each parent and reproductive carrier screening for the parents as a couple. The offer will be made 3-6 months after diagnostic testing. Parents will have access to a modified version of the Genetics Adviser web-based decision support tool before attending a genetic counselling appointment to discuss consent for AF. Parental experiences will be evaluated using qualitative and quantitative methods on data collected through surveys, appointment recordings and interviews at multiple time points. Evaluation will focus on parental preferences, uptake, decision support use and understanding of AF. Genetic health professionals' perspectives on acceptability and feasibility of AF will also be captured through surveys and interviews., Ethics and Dissemination: This project received ethics approval from the Melbourne Health Human Research Ethics Committee as part of the Australian Genomics Health Alliance protocol: HREC/16/MH/251. Findings will be disseminated through peer-review journal articles and at conferences nationally and internationally., Competing Interests: Competing interests: The authors declare no competing interests.

Recent in vivo studies using ultrasound-stimulated microbubbles as a localized radiosensitizer have had impressive results. While in vitro studies have also obtained similar results using human umbilical vein endothelial cells (HUVEC), studies using other cell lines have had varying results. This study was aimed at investigating any increases in radiation-induced cell killing in vitro using two carcinoma lines not previously investigated before (metastatic follicular thyroid carcinoma cells [FTC-238] and non-small cell lung carcinoma cells [NCI-H727]), in addition to HUVEC. Cells were treated using a combination of 1.6% (v/v) microbubbles, ∼90 s of 2-MHz ultrasound (mechanical index = 0.8) and 0-6 Gy of kilovolt or MV X-rays. Cell viability assays obtained 72 h post-treatment were normalized to untreated controls, and analysis of variance was used to determine statistical significance. All cells treated with combined ultrasound-stimulated microbubbles and radiation exhibited decreased normalized survival, with statistically significant effects observed for the NCI-H727 cells. No statistically significant differences in effects were observed using kV compared with MV radiation. Further studies using increased microbubble concentrations may be required to achieve statistically significant results for the FTC-238 and HUVEC lines., Competing Interests: Declaration of Competing Interest The authors declare no conflict of interest., (Copyright © 2022 The Authors.

Introduction: To describe the pattern of the use of advanced radiation therapy (RT) techniques, including intensity-modulated RT (IMRT), volumetric modulated arc therapy (VMAT), and stereotactic body RT (SBRT) for the management of bone metastases (BM), and the associated factors in Victoria., Methods: We used a population-based cohort of patients from the state-wide Victorian Radiotherapy Minimum Data Set (VRMDS) who received RT for BM between 2012 and 2017. The primary outcome was proportion of RT courses using advanced RT techniques. The Cochran-Armitage test for trend was used to evaluate temporal trend in advanced RT use. Multinomial logistic regression was used to identify factors associated with advanced RT use., Results: A total of 18,158 courses of RT were delivered to 10,956 patients-16,626 (91.6%) courses were 3D conformal RT, 857 (4.7%) IMRT/VMAT and 675 (3.7%) SBRT. There was a sharp increase in IMRT/VMAT use from <1% in 2012-2015, to 10.1% in 2016 and 16.3% in 2017 (P-trend < 0.001). Increase in SBRT use was more gradual, from 1.2% in 2012 to 4.8% in 2016 and 5.5% in 2017 for SBRT (P-trend<0.001). In multivariate analyses, year of RT was the strongest predictor of IMRT/VMAT use (OR = 41; 95%CI = 25-67; P < 0.001, comparing 2012-2013 and 2016-2017). Primary tumour type (prostate cancer) was the strongest predictor of SBRT use (OR = 6.07; 95% CI = 4.19-8.80; P < 0.001)., Conclusion: Overall, there was increasing trend in the use of advanced RT techniques for BM in Victoria, with a distinct pattern for IMRT/VMAT compared with SBRT - SBRT uptake was more gradual while IMRT/VMAT uptake was abrupt, occurring contemporaneously with Medicare Benefit Scheme funding changes in 2016., (© 2022 The Authors.

Many individuals approaching the end of life with advanced dementia will live in a care or residential home. A wide spectrum of care is required and physical and safety needs may be prioritised above all other requirements. The Namaste Care Programme is designed to provide a holistic approach to meeting the needs of those with advanced dementia. This paper will outline the process of introducing this programme into a care home and its impact upon those who were involved. With a small sample of residents (n=9) the programme ran for 4 weeks. Feedback was gathered at baseline and during the programme from family and staff. This service innovation offered useful insights and indicated that it has the potential to improve the experiences of those with dementia, their family members and staff. The learning gained will be valuable when developing this initiative at scale and for future robust evaluation.

Aim To increase awareness of the needs of patients with dementia in the trauma and orthopaedics unit of one acute hospital, and to collaborate with staff on the unit to identify ways of improving the care experienced by these patients and their families. Method An action research approach was used and three action research cycles were completed. Data were obtained retrospectively for 20 patients with dementia who were admitted to the unit for treatment. Deficiencies in the care of these patients were identified and related to communication, pain management and the recognition of delirium. In response, a dementia toolkit was developed by nurses and implemented on the unit to improve the care of patients with dementia. Findings Comparison of pre-implementation and post-implementation audit results indicated a significant improvement in all aspects of care for patients with dementia in the trauma and orthopaedics unit, as a result of the implementation of the dementia toolkit. Education and training were provided to staff on the ward to ensure the toolkit was implemented appropriately. Conclusion It is important to consider the specific needs of patients with dementia in acute care settings, not only the primary reason for their admission. The involvement and inclusion of staff in determining what change was needed on the unit, how change would be undertaken and the positive effects of change, demonstrates how action research can inform and improve clinical practice.

Introduction: This article presents the results of a single-day census of radiation therapy (RT) treatment and technology use in Australia. The primary aim of the study was to ascertain patterns of RT practice and technology in use across Australia. These data were primarily collated to inform curriculum development of academic programs, thereby ensuring that training is matched to workforce patterns of practice., Methods: The study design was a census method with all 59 RT centres in Australia being invited to provide quantitative summary data relating to patient case mix and technology use on a randomly selected but common date. Anonymous and demographic-free data were analysed using descriptive statistics., Results: Overall data were provided across all six Australian States by 29 centres of a possible 59, yielding a response rate of 49% and representing a total of 2743 patients. Findings from this study indicate the increasing use of emerging intensity-modulated radiotherapy (IMRT), image fusion and image-guided radiation therapy (IGRT) technology in Australian RT planning and delivery phases. IMRT in particular was used for 37% of patients, indicating a high uptake of the technology in Australia when compared to other published data. The results also highlight the resource-intensive nature of benign tumour radiotherapy., Conclusions: In the absence of routine national data collection, the single-day census method offers a relatively convenient means of measuring and tracking RT resource utilisation. Wider use of this tool has the potential to not only track trends in technology implementation but also inform evidence-based guidelines for referral and resource planning.

Aim: The project aims to assess current specialist practice in relation to the new and ever-changing healthcare climate and explore some of the issues that specialist nurses encounter., Background: The current financial recession is driving a range of economic policy changes and consequently service provision, in particular the work and impact of nurses working in a specialist role, being examined. This has resulted in many specialist nurses feeling very vulnerable., Method: A cross sectional survey was completed by nurses working in specialist roles (n = 96) in a large health and social care setting in the United Kingdom., Findings: A response rate of 62% was achieved: 44% provide nurse led clinics and 42% are nurse prescribers. The mean length of time qualified as a registered nurse was 27 years. Less than a third felt that the current computer system for activity recording reflected their current workload and 65% needed administrative support., Conclusion: This study demonstrates the insufficient resources available to specialist nurses resulting in inappropriate but necessary, use of time and restricted opportunities for learning and development., (© 2013 John Wiley & Sons Ltd.)

In 1995 a cleft liaison service was developed in a health and social care trust which comprises primary and secondary care. The service team includes hospital and community midwives, health visitors and a consultant orthodontist who had a particular interest, and experience in the care of children born with a cleft and often this work was in addition to their existing roles. Anecdotal evidence indicated that the service was of great help to parents but it had never been formally evaluated. Therefore this evaluation was designed to explore the needs and views of parents who had a baby or child with a cleft of the lip and or palate, using a qualitative, cross sectional approach. Following 20 parents interviews responses were recorded, transcribed and a content analysis completed. Three main themes emerged relating to the parents' emotional experiences, their need for information and their experience of caring for a child with a cleft. This study has provided insight into the service delivered by the team and reiterates the need for retaining, maintaining and expanding this specialist service to other localities. Updating midwifery and health visiting staff in terms of knowledge and expertise was implicit to provide a responsive service to meet the needs of the child and family.
