Isocitrate Dehydrogenase 1/2 Wildtype Adult Astrocytoma with WHO Grade 2/3 Histological Features: Molecular Re-Classification, Prognostic Factors, Clinical Outcomes

BACKGROUND

Isocitrate Dehydrogenase 1/2 (IDH 1/2)-wildtype (WT) astrocytomas constitute a heterogeneous group of tumors and have undergone a series of diagnostic reclassifications over time. This study aimed to investigate molecular markers, clinical, imaging, and treatment factors predictive of outcomes in WHO grade 2/3 IDH-WT astrocytomas ('early glioblastoma').

METHODOLOGY

Patients with WHO grade 2/3 IDH-WT astrocytomas were identified from the hospital archives. They were cross-referenced with the electronic medical records systems, including neuroimaging. The expert neuro-pathology team retrieved data on molecular markers-MGMT, TERT, IDH, and EGFR. Tumors with a TERT mutation and/or EGFR amplification were reclassified as glioblastoma.

RESULTS

Fifty-four patients were identified. Sixty-three percent of the patients could be conclusively reclassified as glioblastoma based on either TERT mutation, EGFR amplification, or both. On imaging, 65% showed gadolinium enhancement on MRI. Thirty-nine patients (72%) received long-course radiotherapy, of whom 64% received concurrent chemotherapy. The median follow-up of the group was 16 months (range: 2-90), and the median overall survival (OS) was 17.3 months. The 2-year OS of the whole cohort was 31%. On univariate analysis, older age, worse performance status (PS), and presence versus absence of contrast enhancement on diagnostic MRI were statistically significant for poorer OS.

CONCLUSION

IDH-WT WHO grade 2/3 astrocytomas are a heterogeneous group of tumors with poor clinical outcomes. The majority can be reclassified as glioblastoma, based on current WHO classification criteria, but further understanding of the underlying biology of these tumors and the discovery of novel targeted agents are needed for better outcomes.

Validation of the brain injury associated visual impairment - impact questionnaire (BIVI-IQ)

PURPOSE

The Brain Injury associated Visual Impairment - Impact Questionnaire (BIVI-IQ) was developed to assess the impact of post-stroke visual impairment. The development of the questionnaire used robust methods involving stroke survivors and clinicians. The aim of this study was to assess the validity of the BIVI-IQ in a stroke population.

METHODS

Stroke survivors with visual impairment were recruited from stroke units, outpatient clinics and non-healthcare settings. Participants were asked to complete questionnaire sets on three separate occasions; the BIVI-IQ at each visit with additional questionnaires at baseline and visit 2. Vision assessment and anchor questions from participants and clinicians were collected. The analysis included assessment of missing data, acceptability, Rasch model analysis, test-retest reliability, construct validity (NEI VFQ-25, EQ-5D-5L) and responsiveness to change.

RESULTS

316 stroke survivors completed at least one questionnaire of the 326 recruited. Mean age was 67 years and 64% were male. Adequate fit statistics to the Rasch model were reached (χ2 = 73.12, p = 0.02) with two items removed and thresholds of two adjusted, indicating validity and unidimensionality. Excellent test-retest reliability was demonstrated (ICC = 0.905) with a 3-month interval. Construct validity was demonstrated with a strong significant correlation to the NEI VFQ-25 (r = 0.837, p < 0.01). The BIVI-IQ also demonstrated responsiveness to change with significant differences identified between groups based on participant and clinician anchor questions (X2 = 23.29, p < 0.001; X2 = 24.56, p < 0.001).

CONCLUSION

The BIVI-IQ has been shown to be valid and practical for 'everyday' use by clinicians and researchers to monitor vision-related quality of life in stroke survivors with visual impairment.

Achievement of Target Gain Larger than Unity in an Inertial Fusion Experiment

On December 5, 2022, an indirect drive fusion implosion on the National Ignition Facility (NIF) achieved a target gain G_{target} of 1.5. This is the first laboratory demonstration of exceeding "scientific breakeven" (or G_{target}>1) where 2.05 MJ of 351 nm laser light produced 3.1 MJ of total fusion yield, a result which significantly exceeds the Lawson criterion for fusion ignition as reported in a previous NIF implosion [H. Abu-Shawareb et al. (Indirect Drive ICF Collaboration), Phys. Rev. Lett. 129, 075001 (2022)PRLTAO0031-900710.1103/PhysRevLett.129.075001]. This achievement is the culmination of more than five decades of research and gives proof that laboratory fusion, based on fundamental physics principles, is possible. This Letter reports on the target, laser, design, and experimental advancements that led to this result.

Accelerated Care of Patients with Hip Fractures is Associated with Lower Risk of Delirium and Infection, and a Shorter Length of Hospital Stay: Systematic Review and Meta-analysis of Level One Evidence

Objectives

The aim of this systematic review was to assess the impact of time to surgery on patient mortality, peri-operative complication rates and length of stay following a hip fracture using level one data.

Data Sources

Multiple databases (PubMed, Embase, Medline (Ovid), and Cochrane Library) were searched using terms for "hip fracture" and the intervention "early surgery". Results were filtered to only included randomised controlled trials in the English language published from the year 2000.

Study Selection

All results were imported into Covidence and screened by two separate reviewers with conflicts resolved by a third reviewer. Studies were included if they reported data on the relationship between time to theatre and at least one of the outcome measures (mortality, peri-operative complications, and length of stay in hospital). Three papers were finalised to include in this review.

Data Extraction

Once selected, each paper had a bias assessment completed by two separate reviewers using the Cochrane RoB2 tool. Any conflicts were resolved by a third reviewer.

Data Synthesis

Data from each paper were inputted into RevMan5 for analysis. Approximated sample mean and standard deviation were collected from each paper and included for analysis. RevMan5 was then used to generate forest plots and report data on relative risk and mean difference.

Conclusions

This review has shown that accelerated care of patients with hip fractures was associated with lower risks of delirium and infection, and a shorter length of hospital stay. However, the effect of time to surgery on patient mortality is not clear, as the standard care group had a lower mortality than expected for the population at risk and had surgery on average within 24-h of presentation.

Radiosensitization of Glioblastoma Using Targeted Inhibition of N-Myristoylation

PURPOSE/OBJECTIVE(S)

Treating Glioblastoma remains a major challenge. Radiotherapy has a long-standing role in extending survival, but almost all tumors are expected to recur and be fatal. Historic dose-escalation studies do not yield additional benefit beyond the current 60 Gy dose. Further therapeutic improvement can be gained with radiosensitizers. An undiscovered potential radiosensitization approach may exist in inhibiting the N-myristoylation pathways upregulated in malignant cells. Inhibiting this pathway has been shown to have pleotropic effects including decreasing PARP-1 activity and other cancer-driving pathways that may synergize with radiotherapy. This is a first report in using a targeted N-myristoyltransferase (NMT) inhibitor as a radiosensitizer in glioblastoma.

MATERIALS/METHODS

Immortalized glioma cell lines (U87 and U251) and patient-derived de novo (ED501) and post-chemoradiation recurrent (ED512) cell lines were used to a NMT1/2 inhibitor with radiotherapy. Cell surface expression levels for NMT1 and NMT2 were established using immunofluorescence microscopy. In vitro cell viability studies via mitochondrial reduction of resazurin dye and clonogenic assays were done with single fraction 2 & 4 Gy irradiation with 5 days of drug exposure (5-150 nM 3 days prior to irradiation and 2 days post) to account for drug pharmacodynamics. PARP-1 expression by western blot was tested with exposure to drug and/or radiation. Whole exome sequencing and methylation profiling were done to find predictive markers of radiosensitization.

RESULTS

Preliminary results show significant radiosensitization effect with a dose enhancement factor ranging from 1.33 to 2.71x higher than radiation alone. The amount of radiosensitization varied per cell line, with U251 and ED512 being more sensitive. The cell line sensitivity was not reliably predicted by the NMT cell surface receptor expression. PARP-1 activity increased with radiotherapy but was inhibited with drug exposure. Exome sequencing showed the radiosensitizing effect correlated with mutations in DNA damage repair and myristoylation pathways.

CONCLUSION

N-myristoylation inhibition appears to be a novel method of radiosensitization for glioblastoma. N-myristoylation affects multiple oncogenic pathways including PARP-1 downregulation, which impedes DNA damage repair and may be what leads to radiosensitization. Future studies are aimed at further predictive markers and in vivo efficacy.

Towards optimal use of antithrombotic therapy of people with cancer at the end of life: A research protocol for the development and implementation of the SERENITY shared decision support tool

BACKGROUND

Even though antithrombotic therapy has probably little or even negative effects on the well-being of people with cancer during their last year of life, deprescribing antithrombotic therapy at the end of life is rare in practice. It is often continued until death, possibly resulting in excess bleeding, an increased disease burden and higher healthcare costs.

METHODS

The SERENITY consortium comprises researchers and clinicians from eight European countries with specialties in different clinical fields, epidemiology and psychology. SERENITY will use a comprehensive approach combining a realist review, flash mob research, epidemiological studies, and qualitative interviews. The results of these studies will be used in a Delphi process to reach a consensus on the optimal design of the shared decision support tool. Next, the shared decision support tool will be tested in a randomised controlled trial. A targeted implementation and dissemination plan will be developed to enable the use of the SERENITY tool across Europe, as well as its incorporation in clinical guidelines and policies. The entire project is funded by Horizon Europe.

RESULTS

SERENITY will develop an information-driven shared decision support tool that will facilitate treatment decisions regarding the appropriate use of antithrombotic therapy in people with cancer at the end of life.

CONCLUSIONS

We aim to develop an intervention that guides the appropriate use of antithrombotic therapy, prevents bleeding complications, and saves healthcare costs. Hopefully, usage of the tool leads to enhanced empowerment and improved quality of life and treatment satisfaction of people with advanced cancer and their care givers.

My assistive technology outcomes framework: rights-based outcome tools for consumers to 'measure what matters'

AT outcomes research is the systematic investigation of changes produced by AT in the lives of AT users and their environments. In contrast to focal outcome measures, My Assistive Technology Outcomes Framework (MyATOF) envisions an alternative starting point, co-designing a holistic and evidence-based set of outcome dimensions enabling AT users to quantify their own outcomes. International classification systems, research evidence, regulatory and service delivery frameworks underpin six optional tools: supports, outcomes, costs, rights, service delivery pathway and customer experience. Designed to empower the consumer-as-researcher and self-advocate, MyATOF has the potential to fill an identified gap in policy-relevant, consumer-focussed and consumer-directed outcome measurement in Australia and internationally. This paper presents the need for consumer-focussed measurement and articulates the conceptual foundations of MyATOF. The iterative development and results of MyATOF use-cases collected to date are presented. The paper concludes with next steps in using the Framework internationally, as well as its future development.

The Future of Radioactive Medicine

The discovery of X rays in the late 19th century heralded the beginning of a new age in medicine, and the advent of channeling the power of radiation to diagnose and treat human disease. Radiation has been leveraged in medicine in a multitude of ways and is a critical element of cancer care including screening, diagnosis, surveillance, and interventional treatments. Modern radiotherapy techniques include a multitude of methodologies utilizing both externally and internally delivered radiation from a variety of approaches. This review provides a comprehensive overview of contemporary radiotherapy methodologies, the field of radiopharmaceuticals and theranostics, effects of low dose radiation and highlights the phenomena of fear of exposure to radiation and its impact in modern medicine.

1230 PALLIATIVE CARE MOVEMENT DISORDERS MULTIDISCIPLINARY MEETING

Introduction

It is well recognised that patients with Parkinson’s disease (PD) have significant symptom burden in advanced stages of their disease. Integration of movement disorder and palliative care services has been limited by concerns about resource and sustainability. We present our experience of establishing a movement disorders palliative care multidisciplinary meeting.

Method

In 2019 we established a multidisciplinary virtual bimonthly meeting between movement disorders and palliative care specialists. Referrals were accepted from movement disorder specialists, community Parkinson’s practitioners and palliative care specialists. Referring clinicians all actively applied primary palliative care approaches within their existing services. Aims of the meeting were to facilitate holistic management of complex needs, support advance care planning (ACP) and consider referral to specialist palliative care services.

Result

37 patients in total were discussed over a 2-year period (although the service was limited for a time due to COVID pressures). On average 3 new patients were discussed per meeting. Reasons for referral included motor and non-motor symptoms, support with ACP, medication advice, caregiver concerns and emotional distress. Meeting outcomes included medication adjustments, expediting reviews, hospice support, carer support, and referral to other services. Since the meetings started 23 (62%) patients have died. Of these, 30% died in hospital compared with the national average of 43.4%. The average between discussion at the meeting and death was 139 days. The meeting has generated education opportunities, triggered joint assessments and a professionals’ framework for the palliative management of patients with a movement disorder.

Conclusions

We present the experience of an MDT embedded within an early integrated palliative care service for movement disorders. The MDT has strengthened partnership working and findings suggest that alongside active primary palliative care, specialist palliative care for PD can be sustainable and resource efficient in a UK setting.

Using Small Grants to SPARK! Substantial Reach to Reduce HIV-related Stigma

Community-based organizations (CBOs) are well-positioned to address the negative effects of HIV stigma, which is prevalent in the U.S. South. This article describes a Gilead COMPASS-funded small grants and capacity-building program for CBOs to address stigma and describes the broad reach and positive outcomes associated with program implementation.

Association between radiotherapy protocol variations and outcome in the CONVERT trial

Background

Radiotherapy quality assurance (QA) is integral to radiotherapy delivery. Here we report comprehensive contouring, dosimetry, and treatment delivery QA, describe protocol compliance, and detail the impact of protocol variations on acute grade ≥3 toxicity, progression free survival (PFS), and overall survival (OS) in the phase III CONVERT trial.

Materials/Methods

Radiotherapy planning data from one hundred randomly selected patients were requested. Members of the CONVERT Trial Management Group (TMG) recontoured the heart, lung, and spinal cord organs at risk (OAR) according to the trial guideline. The existing radiotherapy plan were re-applied to the new structures and the new dosimetric data were recollected. Compliance with radiotherapy QA components were recorded and radiotherapy QA components were pooled into protocol variations: acceptable, acceptable variation, and unacceptable variation. Univariable analysis with a Cox proportional hazards model established the relationship between protocol variations and patient outcome.

Results

Ninety-three cases were submitted for retrospective radiotherapy QA review. Demographics of the radiotherapy QA cohort (n=93) matched the non-QA (n=450) cohort. 97.8% of gross tumour volume (GTV) contours were protocol compliant. OAR contours were non-compliant in 79.6% instances of the heart, 37.6% lung, and 75.3% spinal cord. Of the non-compliant heart contours, 86.5% and 2.7% had contours caudal and cranial to the protocol-defined heart borders. 10.8% did not include the pericardial sac and 2.7% did not include the anterior aspect of the pericardium. Eleven (11.8%) submissions exceeded protocol-defined dosimetric heart constraints; six of which were only noted on the application of protocol-compliant contours. Unacceptable variations were not associated with an increase in grade 3 toxicity (p=0.808), PFS (p=0.232), or OS (p=0.743).

Conclusion

Non-protocol compliant heart contours were associated with increased dose delivered to the heart OAR, with 11.8 % of submitted heart structures exceeding protocol-defined constraints. In this QA cohort of patients with small cell lung cancer, unacceptable variations were not associated with acute grade ≥3 toxicity, PFS, or OS. Radiotherapy QA remains the cornerstone of high-quality radiotherapy delivery and should be embedded into clinical trial and non-clinical trial practice; clinical trials should report standardised radiotherapy QA parameters alongside trial outcomes.

Investigating a psychological model of mental conditions and coping during the COVID-19 pandemic driven by participatory methods

BACKGROUND

There is evidence of increased mental health problems during the early stages of the COVID-19 pandemic. We aimed to identify the factors that put certain groups of people at greater risk of mental health problems.

METHODS

We took a participatory approach, involving people with lived experience of mental health problems and/or carers, to generate a set of risk factors and potential moderators of the effects of COVID on mental health. An online cross-sectional survey was completed by 1464 United Kingdom residents between 24th April and 27th June 2020. The survey had questions on whether respondents were existing mental health service users and or carers, level of depression (PHQ9) and anxiety (GAD7), demographics, threat and coping appraisals, perceived resilience (BRS), and specific coping behaviours (validated as part of this study). The relationship between responses and coping strategies was measured using tetrachoric correlations. Structural equation modelling was used to test the model.

RESULTS

A model significantly fit our data (rel χ² = 2.05, RMSEA = 0.029 95%, CI (0.016, 0.042), CFI = 0.99, TLI = 0.98, SRMR = 0.014). Age and coping appraisal predicted anxiety and depression. Whereas, threat appraisal and ethnicity only predicted anxiety, and resilience only predicted depression. Additionally, specific coping behaviours predicted anxiety and depression, with overlap on distraction.

CONCLUSIONS

Some, but not all, risk factors significantly predict anxiety and depression. While there is a relationship between anxiety and depression, different factors may put people at greater risk of one or the other during the pandemic.

Palliative Carboplatin Chemotherapy in Previously Treated High-Grade Glioma: Real-World Efficacy and Safety

AIMS

Effective third-line chemotherapy options for patients after temozolomide (TMZ) and nitrosourea-based chemotherapy for high-grade glioma (HGG) are not well defined. The use of carboplatin is limited due to uncertainly around its effectiveness and tolerability.

METHOD

Patients with HGG treated with single-agent carboplatin chemotherapy between 2005-2021 were identified from our institutional database. Patient and treatment-related details were acquired from electronic hospital records. SPSS Statistics for Windows, (Version 23.0, IBM Corp.) was used for data analysis.

RESULTS

A total of 16 HGG patients were identified. This included 9 glioblastoma (GBM) and 3 anaplastic astrocytomas (AA). These 12 patients were used for further analysis. The median age was 48 (22-73) years. All patients initially received a flat dose of 450 mg intravenous carboplatin every 3-4 weeks. All had previously received high dose RT (54-60 Gy), and temozolomide and lomustine-based chemotherapy. Carboplatin was used as 3rd or 4th line treatment. The median number of cycles given was 3 (range: 1-12). Five had rapid decline in performance status after 1-3 cycles. Five patients required dose/ cycle length adjustment due to grade 1 or 2 haematological toxicity. Other than cumulative fatigue, no other &gt;/= grade 2 toxicities were reported. None required inpatient management for treatment toxicities. Median progression-free survival on carboplatin was 3 months (range 1-11 months) and overall survival was 8 months (range 1–26 months).

CONCLUSION

Carboplatin is a viable treatment option for HGG with acceptable toxicity rates. However, careful patient selection remains key to attaining maximum benefit.

Lawson Criterion for Ignition Exceeded in an Inertial Fusion Experiment

For more than half a century, researchers around the world have been engaged in attempts to achieve fusion ignition as a proof of principle of various fusion concepts. Following the Lawson criterion, an ignited plasma is one where the fusion heating power is high enough to overcome all the physical processes that cool the fusion plasma, creating a positive thermodynamic feedback loop with rapidly increasing temperature. In inertially confined fusion, ignition is a state where the fusion plasma can begin "burn propagation" into surrounding cold fuel, enabling the possibility of high energy gain. While "scientific breakeven" (i.e., unity target gain) has not yet been achieved (here target gain is 0.72, 1.37 MJ of fusion for 1.92 MJ of laser energy), this Letter reports the first controlled fusion experiment, using laser indirect drive, on the National Ignition Facility to produce capsule gain (here 5.8) and reach ignition by nine different formulations of the Lawson criterion.

The COVID-19 Pandemic: Impact on Southern HIV Service Organizations, Staff, and Clients

The COVID-19 pandemic has exacerbated HIV-related disparities and has likely disrupted service provision by organizations providing critical HIV-related services, especially in the U.S. Deep South, an area disproportionately affected by HIV. To assess the impact of COVID-19 on organizations providing services for people living with HIV and/or sexual and gender minorities throughout the Deep South, an online survey was developed and disseminated from January to June 2021 regarding service disruption, organizational changes and needs, and staff and client impact and needs. Organizations reported ongoing organization-level financial and structural complications, staff difficulties including mental health challenges and lack of technology proficiency, and exacerbated challenges for clients including increased mental health concerns, substance use, and housing instability, among others. Organizations will need to be supported as they navigate the exacerbated mental health challenges of clients and staff as well as financially supported as they address economic disparities related to the pandemic.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study

BACKGROUND

Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications.

METHODS

We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC).

FINDINGS

In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]).

INTERPRETATION

In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required.

Perceived Susceptibility to Chronic Kidney Disease and Hypertension Self-Management among Black and White Live Kidney Donors

Background

Despite the societal benefits of live kidney donation, Black donors may be more likely than White donors to develop hypertension (HTN) and chronic kidney disease after donation. Among live kidney donors diagnosed with post-donation HTN, little is known about potential racial/ethnic differences in HTN self-care behaviors and perceived susceptibility to developing kidney disease.

Methods

We ascertained electronic medical records and phone survey data from live donors enrolled in the multi-center Wellness and Health Outcomes of LivE Donors (WHOLE-Donor) Hypertension Care Study between May 2013 and April 2020. Using multivariable logistic regression models performed January through June 2021, we examined potential associations of donor race/ethnicity with perceived susceptibility to kidney disease and self-care behaviors (ie, Behavioral Risk Factor Surveillance System measure assessing self-reported actions to control high blood pressure).

Results

The study included 318 US-based live kidney donors who developed post-donation HTN (57.6% female; 78.9% White; 18.6% Black; and mean age 46.7 years at donation). Black donors were equally as likely as White donors to report being moderately or strongly concerned about developing kidney disease (adjusted odds ratio, aOR: 1.27, 95%CI: .66, 2.14, P=.57). Donors with diabetes were more likely than those without diabetes (aOR: 2.43, 95%CI: 1.03, 5.01, P=.04), while donors aged >50 years were less likely than younger donors (aOR: .39, 95%CI: .18, .85, P=.02) to report being moderately or strongly concerned about kidney disease. Overall, 87% of donors reported taking at least one action to help control blood pressure, with no significant differences by sociodemographic factors.

Conclusions

We found no substantial differences in perceived susceptibility to kidney disease among Black and White donors, despite published evidence that Black donors may experience greater risk of developing kidney disease than White donors. Behavioral interventions to enhance knowledge about future disease risk, attitudes, and self-care strategies among living kidney donors may be beneficial.

779 IMPROVING USE OF COORDINATE MY CARE USING A QUALITY IMPROVEMENT APPROACH FOR MEDICAL PATIENTS ADMITTED TO BARNET HOSPITAL

Introduction

Coordinate My Care (CMC) is a digital care plan for communicating person-centred urgent and advance care planning. We recognised that it was not being consistently accessed on admission, nor updated on discharge, leading to a risk of ignoring patient wishes and previously clinician-agreed care plans. We used a quality improvement approach to increase use of CMC.

Method

We gathered baseline data on the number of users utilising their account, and explored current practice and barriers. A driver diagram was developed, a Steering Group met regularly, and interventions were tested using Plan, Do, Study, Act. Interventions began in January 2021, including electronic circulation of a guide to gain access to CMC, posters about CMC, departmental teaching, and drop-in training. A Core Group of clinicians repeatedly surveyed 12 medical ward areas and offered on-the-spot troubleshooting. To mitigate effects of staff turnover, we developed e-classroom training for new starters.

Results

53 people attended departmental teaching and drop-ins. The number of users utilising their account each month showed a steady increase, rising from 25 to 42 users. Monthly views of CMC records are increasing, with 167 in May 2021 compared to an average of 105 in the 5 months prior to the project. We have still to examine patient feedback.

Conclusion

Use of CMC is becoming more established. Future actions will concentrate on training (including in the emergency department and during junior doctor changeover), helping clinicians hold conversations, and establishing mentoring. Recording Advance Care Planning on CMC is a final step in a complex process of identifying that a patient may be in the last year of their life, starting conversations and taking actions. It follows that varied and sustained actions are needed to improve this, in order to realise the benefits of person-centred planning for our patients and those caring for them.

Mitigating instrument effects in 60 MHz 1H NMR spectroscopy for authenticity screening of edible oils

Low field (60 MHz) ¹H NMR spectroscopy was used to analyse a large (n = 410) collection of edible oils, including olive and argan, in an authenticity screening scenario. Experimental work was carried out on multiple spectrometers at two different laboratories, aiming to explore multivariate model stability and transfer between instruments. Three modelling methods were employed: Partial Least Squares Discriminant Analysis, Random Forests, and a One Class Classification approach. Clear inter-instrument differences were observed between replicated data collections, sufficient to compromise effective transfer of models based on raw data between instruments. As mitigations to this issue, various data pre-treatments were investigated: Piecewise Direct Standardisation, Standard Normal Variates, and Rank Transformation. Datasets comprised both phase corrected and magnitude spectra, and it was found that that the latter spectral form may offer some advantages in the context of pattern recognition and classification modelling, particularly when used in combination with the Rank Transformation pre-treatment.

Identification and Reporting of Gender Identity in HIV Surveillance Data in the Deep South

Introduction

Although studies have identified high prevalence of HIV among individuals who are transgender, HIV surveillance data regarding gender identity is incomplete, resulting in uncertainty regarding the gender identity, including transgender and other diverse gender identities, of individuals diagnosed with HIV. This information is critical to planning strategies for HIV prevention and care.

Methods

From August 2018 to March 2019, interviews were conducted with HIV surveillance leadership (including Surveillance Directors, Epidemiologists, and HIV/STI Prevention Staff) at offices of epidemiology from eight US Deep South states regarding their practices related to gender identity documentation in HIV surveillance data and the barriers encountered in these documentation processes as well as their recommendations for improving gender identity data collection.

Results

Interview findings indicated significant barriers to collection of accurate gender identity information in HIV surveillance data including lack of standardized data systems for collecting gender identity; difficulty obtaining gender identity information from HIV testing sites, laboratories, and medical databases; and need for enhanced cultural sensitivity and gender identity knowledge at all levels of the data collection process. Recommendations from the state HIV surveillance staff, leaders, and epidemiologists are included in the findings.

Conclusions and Policy Implications

Effective, well-coordinated strategies are needed to improve gender identity information in HIV surveillance reporting. Recommendations include standardizing and enhancing data collection strategies, providing cultural sensitivity training at all levels of HIV testing/reporting, and developing formal guidance and providing technical assistance that targets and educates laboratories and medical organizations to implement systems of data collection that routinely and safely capture gender identity data.

The extent and nature of stress of conscience among healthcare workers: A scoping review

BACKGROUND

Healthcare workers experience morally stressful situations during delivery of care which may trouble their conscience. Literature emerging in the context of global pandemics suggest increased frequency of morally stressful situations in healthcare and a link with negative outcomes such as attrition and burnout. Little is known about the emerging concept of stress of conscience which could provide a meaningful way to highlight and address these morally stressful situations in healthcare.

AIM

The aim of this scoping review was to provide an overview of the literature on, (i) the extent, (ii) the factors associated, and (iii) the interventions to prevent or mitigate stress of conscience among healthcare workers.

DESIGN

The study was guided by the framework provided by Arksey and O'Malley in 2005 and the PRISMA Guidelines. Relevant healthcare databases were searched in November 2020 to identify relevant studies.

RESULTS

The search identified 24 studies for inclusion in the analysis, 19 of these were from Nordic countries, particularly Sweden. Across those studies, stress of conscience was prevalent among healthcare workers and the levels varied with demographic factors, individual personalities, perceptions of belonging and the workplace culture and environment. Stress of conscience was associated with negative outcomes such as burnout, moral burden, workplace stress, and low quality of care. Although there were few quality interventions studies, facilitating healthcare workers to provide person-centred care appears to be a promising intervention.

CONCLUSIONS

The concept of stress of conscience provides a contemporary framework to assess, highlight and discuss the degree of the negative impact of perceived violations of professional and personal values in healthcare. However, the limited studies suggest that exploring stress of conscience, including trials of potential interventions, particularly beyond Nordic countries is essential to fill the gaps in the literature.

Adaptation and Preliminary Testing of an Intervention to Reduce Stigma among Individuals Living with HIV in the Deep South

HIV-related stigma has been implicated as a contributor to the disproportionate impact of HIV in the US Deep South. However, effective interventions aimed at reducing HIV-related stigma are limited in the region. This study adapted and piloted an HIV-related stigma reduction intervention, the UNITY Workshop, for use among people living with HIV in the Deep South following a modified framework of the ADAPT-ITT model and the five principles of Corrigan's Model of Strategic Stigma Change. The adapted intervention, named the YOUNITY Workshop, was conducted in an experiential, group format and focused on enhancing stigma coping skills. Workshop satisfaction was high, and most participants reported acquiring new skills for coping with HIV-related stigma and HIV status disclosure. Participants also reported benefitting from the social support generated from the workshop and desired additional opportunities to connect with others in the future. This pilot study demonstrated the feasibility and positive preliminary outcomes of conducting a group-based HIV stigma reduction workshop in the Deep South. Future rigorous testing of the YOUNITY Workshop is planned to better examine health outcomes associated with participation.

Regulating emotion following severe traumatic brain injury: a randomized controlled trial of heart-rate variability biofeedback training

BACKGROUND

While difficulties regulating emotions are almost ubiquitous after traumatic brain injury (TBI), remediation techniques are limited. Heart-rate variability (HRV) is a physiological measure of emotion regulation and can be modified using biofeedback training. The aim of the current study was to evaluate the efficacy of repeated biofeedback training for improving emotion regulation difficulties following TBI.

DESIGN

Fifty adults with severe TBI were allocated to either biofeedback or waitlist conditions. Treatment consisted of six biofeedback sessions whereby participants were taught to breathe at their resonant frequency. Outcomes included changes in physiological and subjective reactivity to anger-induction, emotional well-being, and physiology at rest, together with symptoms of psychological distress and sleep disturbances (ACTRN12618002031246).

RESULTS

While biofeedback led to reduced skin conductance, it did not affect any other objective or subjective response to the mood induction procedure. Biofeedback led to fewer sleep disturbances, and reduced negative mood valence and depression during follow-up.

CONCLUSIONS

HRV biofeedback training is a feasible technique following TBI that transfers to improved symptoms of general emotional well-being, psychological distress, and sleep. Biofeedback does not transfer to a laboratory-based emotional provocation task. HRV biofeedback training may represent a novel adjunct for generalized emotional difficulties following injury.

Nurse practitioner led model of after-hours emergency care in an Australian rural urgent care Centre: health service stakeholder perceptions

Background

The challenges of providing and accessing quality health care in rural regions have long been identified. Innovative solutions are not only required but are also vital if effective, timely and equitable access to sustainable health care in rural communities is to be realised. Despite trial implementation of some alternative models of health care delivery, not all have been evaluated and their impacts are not well understood. The aim of this study was to explore the views of staff and stakeholders of a rural health service in relation to the implementation of an after-hours nurse practitioner model of health care delivery in its Urgent Care Centre.

Methods

This qualitative study included semi-structured individual and group interviews with professional stakeholders of a rural health service in Victoria, Australia and included hospital managers and hospital staff who worked directly or indirectly with the after-hours NPs in addition to local GPs, GP practice nurses, and paramedics. Thematic analysis was used to generate key themes from the data.

Results

Four themes emerged from the data analysis: transition to change; acceptance of the after-hours nurse practitioner role; workforce sustainability; and rural context.

Conclusions

This study suggests that the nurse practitioner-led model is valued by rural health practitioners and could reduce the burden of excessive after-hour on-call duties for rural GPs while improving access to quality health care for community members. As pressure on rural urgent care centres further intensifies with the presence of the COVID-19 pandemic, serious consideration of the nurse practitioner-led model is recommended as a desirable and effective alternative.

HIV Stigma Reduction Through Peer-Led Advocacy Training

HIV-related stigma is pervasive in the U.S. South and has potential negative effects on health outcomes and emotional well-being, and may act as a barrier to HIV-related advocacy among people living with HIV (PLWH). This article reports on the preliminary outcomes associated with participation in an HIV advocacy training for PLWH, LEAD, that included education and skills building for reducing HIV-related stigma. Fifty-seven PLWH at four sites in the U.S. South participated in the retreat-style training and completed a survey measuring stigma and comfort engaging in advocacy prior to and after the worshop. Participation was associated with statistically significant reduction in internalized HIV stigma and increase in comfort with participation in advocacy; however, participants reported a need for ongoing training and support to further increase comfort with advocacy participation. Although more research is needed on the LEAD Workshop, it shows promise as an option for reducing HIV-related stigma among PLWH.

Trocar site closure with a novel anchor-based (neoClose®) system versus standard suture closure: A prospective randomized controlled trial

Objective

Patients with obesity have a higher risk of trocar site hernia. The objective of the present study was to compare a standard suture passer versus the neoClose® device for port site fascial closure in patients with obesity undergoing laparoscopic bariatric surgery.

Methods

This is a randomized, controlled trial with two parallel arms. Thirty five patients with BMI ≥ 35 kg/m2 and undergoing laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass were randomized to each group. Port site fascial closure for trocars ≥ 10 mm was performed with the neoClose® device in the study group and the standard suture passer in the control group. Primary outcomes were time required to complete closure and intensity of postoperative pain at the fascial closure sites. Secondary outcomes were intraabdominal needle depth and incidence of trocar site hernia.

Results

The use of the neoClose® device resulted in shorter closure times (20.2 vs 30.0 s, p = 0.0002), less pain (0.3 vs 0.9, p = 0.002) at port closure sites, and decreased needle depth (3.3 cm vs 5.2 cm, p &lt; 0.0001) compared to the standard suture passer. There was no trocar site hernia at the one-year follow-up in either group.

Conclusion

Use of the neoClose® device resulted in faster fascial closure times, decreased intraoperative needle depth, and decreased postoperative abdominal pain at 1 week as compared to the standard suture passer. These data need to be confirmed on larger cohorts of patients with longer follow-up, especially in terms of long-term hernia recurrence rates.

Can quantitative 18F-FDG PET/CT and serum cytokine analysis differentiate ARVC from cardiac sarcoidosis?

Background

Arrhythmogenic right ventricular cardiomyopathy (ARVC) and Cardiac Sarcoidosis (CS) may both cause malignant arrhythmia and sudden death, but differentiating the two can be difficult.

Purpose

To investigate the role of quantitative FDG PET/CT at distinguishing ARVC from CS, and explore whether addition of an inflammatory panel correlates with PET uptake, aiding diagnosis.

Methods

10 patients with CS, 10 with ARVC were enrolled. Participants were prospectively studied with PET/CT. LV uptake was quantified using software and a 17-segment model, measuring maximum standardised uptake (SUVmax) and mean myocardial uptake, comparing these to a local normal reference range (21 volunteers) using a z-score. Blood levels of IL-1b, IL-6, IL-8, IL10, IL-12p40, MCP-1, TGFb, GRO, TNFa, IFNy, FGF2, PDGF were measured using ELISA, compared with 10 healthy controls.

Results

There were no significant differences in cytokine levels between CS and ARVC; most cytokine levels were higher in CS, except IL-6, IL-8 and MCP-1 in ARVC (Table 1). Increased PET uptake was noted in 1 segment of 1 ARVC patient, and in 1–2 segments of 5 CS patients (z-scores 2.25 SD; 2.15–2.38 SD). No pattern of uptake distinguished ARVC from CS, qualitatively assessing LV polar maps (Figure 1A, B). SUVmax and mean uptake were higher in CS vs. ARVC (p&lt;0.05; p=0.13). No significant correlation between cytokine levels and PET uptake was detected (Figure 1C, D).

Conclusion

Quantitative PET/CT uptake and a blood inflammatory panel did not have utility in differentiating the two conditions in our population. There was generally more PET and serum inflammatory activity in CS.

Ethical challenges experienced by researchers in community-based participatory research

Background

Political, economic and climate events continue to bring the dismantling of communities and creation of new ones. Understanding successful models of adaptation and working with communities to address their health and wellbeing needs requires ethically sound public health research. Community-Based Participatory Research (CBPR) has been proposed as an equitable, empowering partnership approach to collaborative health research that encapsulates analysis, advocacy and action for the future wellbeing of communities. Meanwhile, a strong interest in ethical implications of CBPR continues in international literature, yet with a notable lack of research that captures the experience of researchers who had ethical challenges in their CBPR studies. The aim of this research was to address this lack of evidence by exploring those experiences of CBPR researchers internationally.

Methods

An innovative data collection method was designed utilising a purpose-built blog. This internet-based, qualitative online study enabled asynchronous international data collection on the blog. Participants were researchers with experience of CBPR and were recruited through social media platforms. Blog narratives of first-hand experiences of CBPR researchers were analysed using thematic analysis.

Results

The themes that emerged from blog data analysis were researchers' challenges with balancing participant protection and autonomy, dealing with partnership tensions, and the enduring impacts on the researchers.

Conclusions

This study enhances our understanding of ethical challenges in CBPR with evidence of enduring impacts on researchers of the 'tightrope' they walked in the interests of maintaining research integrity and ethical responsibility towards their partnering communities. Challenges arose largely from complexities of CBPR coupled with rigid regulatory structures of human research ethics review that struggles to respond adequately in the interests of communities and researchers.

Key messages

At this critical time for the future of humanity, communities can benefit from CBPR. A positive way forward for ethical review of CBPR exists for those with power to make a difference.

Differences for managing mother’s own milk for very preterm infants across 11 European countries

Background

There is an ongoing debate about the best practices to handle mother's own milk (MOM) for infants born very preterm (VPT, ≤32 weeks of gestation), specifically to prevent the human cytomegalovirus (HCMV) transmission and bacterial contamination of expressed MOM. Thus, we aimed to compare practices for managing MOM for VPT infants in European neonatal intensive care units (NICUs).

Methods

Data were collected as part of the EPICE (Effective Perinatal Intensive Care in Europe) study which explored the use of evidence-based practices for the care of VPT infants in 11 European countries. Structured questionnaires were sent to the head of all participating NICUs with at least 10 VPT admissions. Of the eligible 135 NICUs, 134 replied.

Results

A written protocol for breastfeeding/human milk use was available in 91% of the NICUs. Overall, 34% used human bank milk for all VPT infants whose mothers did not express and 56% reported using fresh MOM without restrictions regarding minimum gestational age, birth weight or risk of HCMV transmission (country range: 0-100%). In 22% of units all VPT infants received MOM pasteurized (country range: 0-73%). HCMV serology on all mothers who express their milk was not required in 71% of units (country range: 7-100%). Among NICUs that performed HCMV serology, 3% provided untreated fresh MOM and 23.5% formula in the case of positive mothers. Systematic bacteriological analyses of MOM were not performed in 76% NICUs (country range: 29-100%) while less than 10% did it for the first milk feeding, 7% every week and 8% with another frequency.

Conclusions

There are large variations in managing MOM across countries, which could reflect differences in regulations or guidelines, and among the same country NICUs, revealing that different options can operate locally. This variability suggests substantial differences in attitudes about what constitutes best practices among European neonatologists.

Key messages

We found significant differences across and within European countries for managing MOM for VPT infants suggesting lack of strong recommendations at the international and national level. There is wide variation in what European neonatologists consider best practices. To guide practice and not jeopardise VPT infants from MOM we need strong evidence-based data.

Social media support group: Implementation and evaluation

Lack of social support and perceived HIV-related stigma increase the risk of negative health-related outcomes among people living with HIV (PLWH). This study examines the social media use of PLWH participating in a behavioral health treatment program, and the association of participation in a "secret" Facebook group with improved client social support, education, and overall behavioral health treatment experience. Eighteen individuals participated in a survey and eight individuals participated in a focus group regarding their familiarity with technology and experience with using social media. Mixed-method analysis revealed that the majority of "secret" Facebook group participants thought that participation in the group improved overall personal wellbeing and perceived social support. However, lack of technology and social media experience and privacy concerns may have contributed to lower levels of participation with the "secret" Facebook group. A majority of participants who found Facebook difficult to use and/or had less technology experience were over the age of 50. Incorporating additional technology training for individuals who lack technology experience has the potential to improve clients' overall proficiency with technology and social media, as well as build confidence that could translate into an increased willingness to participate in a social media-based intervention.

Strength of public preferences for endovascular or open aortic aneurysm repair

Background

This study evaluated public preferences for the treatment processes for abdominal aortic aneurysm repair in order to allow them to be incorporated into a cost-effectiveness analysis.

Methods

This was a telephone survey using a trade-off method in UK resident adults (aged at least 18 years) with no previous diagnosis of a vascular condition.

Results

Some 167 of 209 participants (79·9 per cent) stated that they would prefer endovascular aneurysm repair (EVAR), 40 (19·1 per cent) preferred open surgery and two (1·0 per cent) stated no preference. Participants preferred EVAR because of the less invasive nature of the intervention and quicker recovery. Participants preferring open surgery cited reasons such as having a single follow-up appointment, and a procedure that felt more permanent. When participants were asked to make a sacrifice in order to have their preferred treatment, 122 (58·4 per cent) favoured EVAR, 18 (8·6 per cent) favoured open surgery and 69 (33·0 per cent) had no preference. Those preferring EVAR were willing to give up a mean of 0·135 expected quality-adjusted life-years (QALYs) to have EVAR, compared with a willingness to give up 0·033 expected QALYs among those preferring open repair.

Conclusion

These results indicate a clear preference for EVAR over open surgery for aortic aneurysm.

State of HIV in the US Deep South

The Southern United States has been disproportionately affected by HIV diagnoses and mortality. To inform efforts to effectively address HIV in the South, this manuscript synthesizes recent data on HIV epidemiology, care financing, and current research literature on factors that predispose this region to experience a greater impact of HIV. The manuscript focuses on a specific Southern region, the Deep South, which has been particularly affected by HIV. Epidemiologic data from the Centers from Disease Control and Prevention indicate that the Deep South had the highest HIV diagnosis rate and the highest number of individuals diagnosed with HIV (18,087) in 2014. The percentage of new HIV diagnoses that were female has decreased over time (2008-2014) while increasing among minority MSM. The Deep South also had the highest death rates with HIV as an underlying cause of any US region in 2014. Despite higher diagnosis and death rates, the Deep South received less federal government and private foundation funding per person living with HIV than the US overall. Factors that have been identified as contributors to the disproportionate effects of HIV in the Deep South include pervasive HIV-related stigma, poverty, higher levels of sexually transmitted infections, racial inequality and bias, and laws that further HIV-related stigma and fear. Interventions that address and abate the contributors to the spread of HIV disease and the poorer HIV-related outcomes in the Deep South are warranted. Funding inequalities by region must also be examined and addressed to reduce the regional disparities in HIV incidence and mortality.

Hepatitis C genotype change after transplantation utilizing hepatitis C positive donor organs

A shortage in organs for transplantation has led to the increased use of hepatitis C (HCV) infected donor organs for solid organ transplant recipients infected with HCV. However, the donor HCV genotype is not routinely checked or known prior to transplant. Here, we report 4 cases of genotype conversion after transplantation in patients receiving HCV infected donor organs. This change in genotype may potentially impact HCV progression as well as treatment choice for these patients.

Comparison between a multicentre, collaborative, closed-loop audit assessing management of supracondylar fractures and the British Orthopaedic Association Standard for Trauma 11 (BOAST 11) guidelines

Aims

Supracondylar fractures are the most frequently occurring paediatric fractures about the elbow and may be associated with a neurovascular injury. The British Orthopaedic Association Standards for Trauma 11 (BOAST 11) guidelines describe best practice for supracondylar fracture management. This study aimed to assess whether emergency departments in the United Kingdom adhere to BOAST 11 standard 1: a documented assessment, performed on presentation, must include the status of the radial pulse, digital capillary refill time, and the individual function of the radial, median (including the anterior interosseous), and ulnar nerves.

Materials and Methods

Stage 1: We conducted a multicentre, retrospective audit of adherence to BOAST 11 standard 1. Data were collected from eight hospitals in the United Kingdom. A total of 433 children with Gartland type 2 or 3 supracondylar fractures were eligible for inclusion. A centrally created data collection sheet was used to guide objective analysis of whether BOAST 11 standard 1 was adhered to. Stage 2: We created a quality improvement proforma for use in emergency departments. This was piloted in one of the hospitals used in the primary audit and was re-audited using equivalent methodology. In all, 102 patients presenting between January 2016 and July 2017 were eligible for inclusion in the re-audit.

Results

Stage 1: Of 433 patient notes audited, adherence to BOAST 11 standard 1 was between 201 (46%) and 232 (54%) for the motor and sensory function of the individual nerves specified, 318 (73%) for radial pulse, and 247 (57%) for digital capillary refill time. Stage 2: Of 102 patient notes audited, adherence to BOAST 11 standard 1 improved to between 72 (71%) and 80 (78%) for motor and sensory function of the nerves, to 84 (82%) for radial pulse, and to 82 (80%) for digital capillary refill time. Of the 102 case notes reviewed in stage 2, only 44 (43%) used the quality improvement proforma; when the proforma was used, adherence improved to between 40 (91%) and 43 (98%) throughout.

Conclusion

Adherence to BOAST 11 standard 1 is poor in hospitals across the country. This is concerning as neurovascular deficit may be an indication for emergent surgery, and missed neurovascular injury can cause long-term, or even permanent, functional impairment. We present a simple proforma that improves adherence to this standard, can easily be implemented into emergency departments, and may improve patient safety.

The impact of route of diagnosis on survival in patients with glioblastoma

INTRODUCTION

The standard of care for glioblastoma is maximal debulking surgery followed by chemo-radiotherapy (CRT). Published data show worse outcomes for patients who present with GBM as an emergency. This study investigates prognostic factors in a cohort of GBM patients treated with postoperative CRT, and compares outcomes in patients who present via emergency pathways with those who present through outpatient clinics.

METHODS

Patients with GBM operated on between 1 April 2010 and 5 October 2015 and then treated with postoperative CRT were included in the study. Data were collected from electronic patient records and radiotherapy planning systems. Survival data were censored on 22 March 2016. Univariate and multivariate analyses of prognostic factors were performed.

RESULTS

104 patients were studied; mean age 51.6 years (range 19 to 70 years). Median overall survival (OS) was 16.5 months, with 68.2% and 37.8% alive at 12 and 24 months respectively. On multivariate analysis, improved OS was associated with ECOG Performance Status of 0 (vs ≥1; p = .012), patient age <60 years (vs ≥60 years; p < .001), and surgical debulking or macroscopic complete resection (vs biopsy; p < .001). Patients who presented through emergency medical pathways had worse survival (p = .005).

CONCLUSION

This study supports published data that initial presentation through emergency pathways is associated with worse outcomes in GBM, even in patients who remain fit enough to receive post-operative CRT.

Social and structural conditions for the avoidance of advance care planning in neuro-oncology: a qualitative study

BACKGROUND

Primary brain tumours newly affect >260 000 people each year worldwide. In the UK, every year >10 000 people are diagnosed with a brain tumour while >5000 die annually from the disease. Prognoses are poor, cognitive deterioration common and patients have prolonged palliative needs. Advance care planning (ACP) may enable early discussion of future care decisions. Although a core commitment in the UK healthcare strategy, and the shared responsibility of clinical teams, ACP appears uncommon in practice. Evidence around ACP practice in neuro-oncology is limited.

OBJECTIVES

We aimed to elicit key social and structural conditions contributing to the avoidance of ACP in neuro-oncology.

DESIGN

A cross-sectional qualitative study design was used.

SETTING

One tertiary care hospital in the UK.

PARTICIPANTS

Fifteen healthcare professionals working in neuro-oncology participated in this study, including neuro-oncologists, neurosurgeons, clinical nurse specialists, allied healthcare professionals and a neurologist.

METHOD

Semi-structured interviews were conducted with participants to explore their assumptions and experiences of ACP. Data were analysed thematically using the well-established framework method.

RESULTS

Participants recognised the importance of ACP but few had ever completed formal ACP documentation. We identified eight key factors, which we suggest comprise three main conditions for avoidance: (1) difficulties being a highly emotive, time-intensive practice requiring the right 'window of opportunity' and (2) presence and availability of others; (3) ambiguities in ACP definition, purpose and practice. Combined, these created a 'culture of shared avoidance'.

CONCLUSION

In busy clinical environments, 'shared responsibility' is interpreted as 'others' responsibility' laying the basis for a culture of avoidance. To address this, we suggest a 'generalists and specialists' model of ACP, wherein healthcare professionals undertake particular responsibilities. Healthcare professionals are already adopting this model informally, but without formalised structure it is likely to fail given a tendency for people to assume a generalist role.

Lifetime measurement in neutron-rich A~100 nuclei

Lifetimes of excited states of the 98;100;102Zr nuclei were measured by using the Generalized Centroid Difference Method. The nuclei of interest were populated via neutron-induced fission of 241Pu and 235U during the EXILL-FATIMA campaign. The obtained lifetimes were used to calculate the B(E2) transition strengths and β deformation parameters which were then compared with the recent theoretical predictions obtained with Monte Carlo Shell Model.

Rural health services and the task of community participation at the local community level: a case study

Community participation in health service decision making is entrenched in health policy, with a strong directive to develop sustainable, effective, locally responsive services. However, it is recognised that community participation is challenging to achieve. The aim of the present study was to explore how a rural health service in Victoria enacts community participation at the local level. Using case study methodology, the findings indicate that enactment of community participation is desired by the health service, but a lack of understanding of the concept and how to enact associated policy are barriers that are exacerbated by a lack of resources and community capacity. The findings reveal a disconnect between community participation policy and practice. What is known about the topic? The need to involve communities in health service planning, implementation and evaluation is a feature of health policy across major Western countries. However, researchers have identified a dearth of research on how community participation is enacted at the local service level. What does this paper add? The study that is presented herein addresses a gap in knowledge of community participation policy enactment within a rural health service. Insights are provided into the challenges faced by rural health services, with a disconnect between policy ideal and the reality of implementation. What are the implications for practitioners? Health service staff need clear direction from chief executive officers about the purpose of community participation policy and the expectations for individual roles. Community advisory committees need clarity about the community member role and the processes for making decisions. Services and their boards would benefit from targeted government funding to resource community participation activity.
