    Abstract An increasing number of people are infected with antibiotic-resistant bacteria each year, sometimes with fatal consequences. In this manuscript, we report a novel urea-functionalized crown ether that can bind to the bacterial lipid phosphatidylethanolamine (PE), facilitate PE flip-flop and displays antibacterial activity against the Gram-positive bacterium Bacillus cereus with a minimum inhibitory concentration comparable to that of the known PE-targeting lantibiotic duramycin.

    Abstract Issue addressed: The ASQ-TRAK, a strengths-based approach to developmental screening, has high acceptability and utility across varied Aboriginal and Torres Strait Islander contexts. While substantive knowledge translation has seen many services utilise ASQ-TRAK, we now need to move beyond distribution and support evidence-based scale-up to ensure access. Through a co-design approach, we aimed to (1) understand community partners' perspectives of barriers and enablers to ASQ-TRAK implementation and (2) develop an ASQ-TRAK implementation support model to inform scale-up.
    Methods: The co-design process had four phases: (i) partnership development with five community partners (two Aboriginal Community Controlled Organisations); (ii) workshop planning and recruitment; (iii) co-design workshops; and (iv) analysis, draft model and feedback workshops.
    Results: Seven co-design meetings and two feedback workshops with 41 stakeholders (17 were Aboriginal and Torres Strait Islander), identified seven key barriers and enablers, and a shared vision - all Aboriginal and Torres Strait Islander children and their families have access to the ASQ-TRAK. Implementation support model components agreed on were: (i) ASQ-TRAK training, (ii) ASQ-TRAK support, (iii) local implementation support, (iv) engagement and communications, (v) continuous quality improvement and (vi) coordination and partnerships.
    Conclusions: This implementation support model can inform ongoing processes necessary for sustainable ASQ-TRAK implementation nationally. This will transform the way services provide developmental care to Aboriginal and Torres Strait Islander children, ensuring access to high quality, culturally safe developmental care. SO WHAT?: Well-implemented developmental screening leads to more Aboriginal and Torres Strait Islander children receiving timely early childhood intervention services, improving developmental trajectories and optimising long-term health and wellbeing.

    Abstract Background: Previous research reviewed treatment success and whether the collective uncertainty principle is met in RCTs in the US National Cancer Institute portfolio. This paper classifies clinical trials funded by the UK HTA programme by results using the method applied to the US Cancer Institute trials, and compares the two portfolios.
    Methods: Data on all completed randomised controlled trials funded by the HTA programme 1993-2008 were extracted. Each trial's primary results was classified into six categories; 1) statistically significant in favour of the new treatment, 2) statistically significant in favour of the control treatment 3) true negative, 4) truly inconclusive, 5) inconclusive in favour of new treatment or 6) inconclusive in favour of control treatment. Trials were classified by comparing the 95% confidence interval for the difference in primary outcome to the difference specified in the sample size calculation. The results were compared with Djulbegovic's analysis of NCI trials.
    Results: Data from 51 superiority trials were included, involving over 48,000 participants and a range of diseases and interventions. 85 primary comparisons were available because some trials had more than two randomised arms or had several primary outcomes. The new treatment had superior results (whether significant or not) in 61% of the comparisons (52/85 95% CI 49.9% to 71.6%). The results were conclusive in 46% of the comparisons (19% statistically significant in favour of the new treatment, 5% statistically significant in favour of the control and 22% true negative). The results were classified as truly inconclusive (i.e. failed to answer the question asked) for 24% of comparisons (20/85). HTA trials included fewer truly inconclusive and statistically significant results and more results rated as true negative than NCI trials.
    Conclusions: The pattern of results in HTA trials is similar to that of the National Cancer Institute portfolio. Differences that existed were plausible given the differences in the types of trials -HTA trials are more pragmatic. The results indicate HTA trials are compatible with equipoise. This classification usefully summarises the results from clinical trials and enables comparisons of different portfolios of trials.

    Abstract Delivering difficult news is a common occurrence in genetic counseling. This is evidenced by widespread instruction among genetic counseling programs. There is a disconnect in the confidence level of being able to deliver difficult news (DDN) following educational training across healthcare disciplines. Other healthcare professions have addressed this issue with simulation-based training based on the SPIKES protocol, a stepwise process for delivering difficult news. To our knowledge, there is limited research that investigates the impact of simulation-based training in delivering difficult news for genetic counselors. Our aim was to develop simulation-based training in how to deliver difficult news for genetic counselors and analyze the extent to which it increased their confidence to deliver difficult news. Board-certified genetic counselors from all specialties were recruited to participate in a 2-h training session which included the opportunity to practice delivering difficult news. We collected self-reported confidence scores in each of the SPIKES steps from 16 genetic counselors pre- and post-intervention. Participants answered open-ended evaluations about the program's strengths, weaknesses, and gaps in delivering difficult news content. Almost all participants (N = 15) stated that they had gained confidence in delivering difficult news following training completion. Confidence significantly improved in four of seven SPIKES steps. Participants found strengths of the training program to be in their ability to practice with a simulated patient, to reference concrete examples, and to follow the program easily. The results of this study suggest that post-graduate training in how to deliver difficult news using the SPIKES protocol may strengthen genetic counselors' confidence in performing this important skill.

    Abstract Introduction: Frailty is associated with adverse outcomes among patients attending emergency departments (EDs). While multiple frailty screens are available, little is known about which variables are important to incorporate and how best to facilitate accurate, yet prompt ED screening. To understand the core requirements of frailty screening in ED, we conducted an international, modified, electronic two-round Delphi consensus study.
    Methods: A two-round electronic Delphi involving 37 participants from 10 countries was undertaken. Statements were generated from a prior systematic review examining frailty screening instruments in ED (logistic, psychometric and clinimetric properties). Reflexive thematic analysis generated a list of 56 statements for Round 1 (August-September 2021). Four main themes identified were: (i) principles of frailty screening, (ii) practicalities and logistics, (iii) frailty domains and (iv) frailty risk factors.
    Results: In Round 1, 13/56 statements (23%) were accepted. Following feedback, 22 new statements were created and 35 were re-circulated in Round 2 (October 2021). Of these, 19 (54%) were finally accepted. It was agreed that ideal frailty screens should be short (<5 min), multidimensional and well-calibrated across the spectrum of frailty, reflecting baseline status 2-4 weeks before presentation. Screening should ideally be routine, prompt (<4 h after arrival) and completed at first contact in ED. Functional ability, mobility, cognition, medication use and social factors were identified as the most important variables to include.
    Conclusions: Although a clear consensus was reached on important requirements of frailty screening in ED, and variables to include in an ideal screen, more research is required to operationalise screening in clinical practice.

    Abstract Background: Most systematic reviews conclude that another clinical trial is needed. Measures of sufficiency and stability may indicate whether this is true.
    Objectives: To show how evidence accumulated on centre-based versus home-based cardiac rehabilitation, including estimates of sufficiency and stability
    Methods: Systematic reviews of clinical trials of home versus centre-based cardiac rehabilitation were used to develop a cumulative meta-analysis over time. We calculated the standardised mean difference (SMD) in effect, confidence intervals and indicators of sufficiency and stability. Sufficiency refers to whether the meta-analytic database adequately demonstrates that an intervention works - is statistically superior to another. It does this by assessing the number of studies with null results that would be required to make the meta-analytic effect non-statistically significant. Stability refers to whether the direction and size of the effect is stable as new studies are added to the meta-analysis.
    Results: The standardised mean effect difference reduced over fourteen comparisons from a non-significant difference favouring home-based cardiac rehabilitation to a very small difference favouring hospital (SMD -0.10, 95% CI -0.32 to 0.13). This difference did not reach the sufficiency threshold (failsafe ratio 0.039<1) but did achieve the criteria for stability (cumulative slope 0.003<0.005).
    Conclusions: The evidence points to a relatively small effect difference which was stable but not sufficient in terms of the suggested thresholds. Sufficiency should arguably be based on substantive significance and decided by patients. Research on patient preferences should be the priority. Sufficiency and stability measures are useful tools that need to be tested in further case studies.
