'Building our own house' as an insider-only Community-Partnered Participatory Research Council: Co-creating a safe space for Autistic knowledge production

LAY ABSTRACT

In recent years, there has been a growing call for participatory Autism research (i.e. research that meaningfully involves Autistic people in its design and delivery). Community Partnered Participatory Research is a research methodology that aims to share power between researchers and members of the researched community. There is some precedent for Community Partnered Participatory Research in Autism research, but it is still quite uncommon. At the start of our new research study (called Autism: From Menstruation to Menopause), we created a community council. For the first six meetings, our council was made up of four Autistic community members who were experienced in Autism advocacy and activism and three Autistic researchers. We seven are the authors of this article. In these first six meetings, we made plans for recruiting a larger number of lay community members who would join us later for the rest of the project (8 years in total). In this article, we describe and reflect what it felt like during these first six meetings to be part of a community research council where everybody is Autistic. We discuss how we co-created a safe space, how we helped each other feel valued and how we worked together to support each other's sometimes-differing access needs so that everyone could fully participate. We provide recommendations for how to support Autistic people to lead research on their own terms with their unique insights.

Lived experience of work and long COVID in healthcare staff

BACKGROUND

Healthcare workers (HCWs) had a greater occupational risk of exposure to coronavirus disease 2019 (COVID-19) and reported higher rates of long COVID (LC). This has implications for the provision of health care in already stretched health services.

AIMS

This study explored the impact of LC on a range of UK National Health Service (NHS) HCWs, their health and well-being, the effect on work patterns, and occupational support received.

METHODS

Mixed-methods study, online survey and qualitative interviews. Participants self-reporting LC symptoms were recruited through social media and NHS channels. Interviews used maximum variation sampling of 50 HCWs including healthcare professionals, ancillary and administration staff. Thematic analysis was conducted using NVivo software.

RESULTS

A total of 471 HCWs completed the online survey. Multiple LC symptoms were reported, revealing activity limitations for 90%. Two-thirds had taken sick leave, 18% were off-work and 33% reported changes in work duties. There were few differences in work practices by occupational group. Most participants were working but managing complex and dynamic symptoms, with periods of improvement and exacerbation. They engaged in a range of strategies: rest, pacing, planning and prioritizing, with work prioritized over other aspects of life. Symptom improvements were often linked to occupational medicine, managerial, colleague support and flexible workplace adjustments.

CONCLUSIONS

LC has a significant impact on the lives of HCWs suffering prolonged symptoms. Due to the variability and dynamic nature of symptoms, workplace support and flexible policies are needed to help retain staff.

"It felt like I had an old fashioned telephone ringing in my breasts": An online survey of UK Autistic birthing parents' experiences of infant feeding

Around 3% of people are Autistic. Autistic people communicate differently from non-Autistic people and experience the sensory world differently. There is limited evidence that Autistic people can face additional barriers to breastfeeding. We are an Autistic-led research team that developed an online survey following consultation with the Autistic community. Autistic people from the UK who had been pregnant were eligible to take part in the survey, which focused on the entire maternity journey. A total of 193 people participated, of whom 152 had experiences of infant feeding (137 breastfeeding, 82 formula feeding). Participants were highly motivated to breastfeed, and almost half of those who breastfed found it positive always or most of the time. However, breastfeeding-and in particular the milk let-down reflex-could result in pain and sensory difficulties, including 'feeling odd'. Expressing breastmilk always or most of the time was reported by 10% of breastfeeding participants. The intensity and unpredictability of both breast and formula feeding were challenging to manage. Parents reported that it was easy to understand how to prepare infant formula, but that it could also be a negative and anxiety-inducing experience. Support for breast and formula feeding was often considered inadequate. When parents did access breastfeeding support, this significantly improved a range of breastfeeding experiences. However, participants recommended more tailored support and continuity of carer. To meet the needs of Autistic birthing parents, those providing infant feeding support should receive training on Autism through a neurodiversity-affirming lens, which should be delivered by Autistic people.

The safety of at home powdered infant formula preparation: A community science project

Formula fed infants experience gastrointestinal infections at higher rates than breastfed infants, due in part to bacteria in powdered infant formula (PIF) and bacterial contamination of infant feeding equipment. The United Kingdom National Health Service (UK NHS) has adopted the World Health Organization recommendation that water used to reconstitute PIF is ≥70°C to eliminate bacteria. We used community science methods to co-design an at home experiment and online questionnaire ('research diary') to explore the safety of PIF preparation compared to UK NHS guidelines. 200 UK-based parents of infants aged ≤12 months were recruited; 151 provided data on PIF preparation, and 143 were included in the analysis of water temperatures used to reconstitute PIF. Only 14.9% (n = 11) of 74 PIF preparation machines produced a water temperature of ≥70°C compared with 78.3% (n = 54) of 69 kettle users (p < 0.001). The mean temperature of water dispensed by PIF preparation machines was 9°C lower than kettles (Machine M = 65.78°C, Kettle M = 75.29°C). Many parents did not always fully follow NHS safer PIF preparation guidance, and parents did not appear to understand the potential risks of PIF bacterial contamination. Parents should be advised that the water dispensed by PIF preparation machines may be below 70°C, and could result in bacteria remaining in infant formula, potentially leading to gastrointestinal infections. PIF labelling should advise that water used to prepare PIF should be ≥70°C and highight the risks of not using sufficiently hot water, per WHO Europe advice. There is an urgent need for stronger consumer protections regarding PIF preparation devices.

Complication Avoidance of Reconstruction Implant Radiation Therapy (CARIT): A Retrospective Case-Cohort Analysis

PURPOSE/OBJECTIVE(S)

Patients are increasingly offered implant-based reconstruction prior to radiotherapy. However, it is unclear if the radiation treatment technique itself impacts upon toxicity. We performed this study to compare outcomes following implant-based reconstruction amongst breast cancer patients treated with a standard radiotherapy technique that irradiates the entire chest wall versus a novel technique which uses a smaller clinical target volume (CTV) to spare the implant. Need for corrective surgery, capsular contracture, and cosmetic outcomes were evaluated, with the hypothesis that the novel technique would result in fewer adverse outcomes and less need for corrective surgery.

MATERIALS/METHODS

A retrospective case-cohort analysis of 57 patients who had post-mastectomy, implant-based reconstruction was conducted. Patients with invasive mammary carcinoma (IMC) or ductal carcinoma in-situ (DCIS) who were treated either with the novel radiotherapy technique (n = 26) or standard PMRT (n = 31) were included. Patient demographics such as age, BMI, TNM stage, implant size, hormone receptor status, and radiation course was collected. Primary endpoint was the need for corrective surgery within two years and cosmetic outcomes, measured using the Baker Classification Scale for capsular contracture and the Modified Harvard Harris Cosmetic Scale. Secondary endpoint was radiation-induced toxicity measured using the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE). Cosmesis and toxicity were evaluated at 3 months post-radiation, 1 year, and after 13 months. Unpaired t-tests were used to compare need for corrective surgery, cosmesis (Baker Grade 2 or higher and Harvard Harris "Good" or worse), and toxicity (NCI CTCAE Grade 2 or higher).

RESULTS

For the primary endpoint, need for corrective surgery, there was no significant difference between the novel and standard groups (two-sided p = 0.378, CI -0.38-0.14). The other primary endpoint of cosmesis, measured with the Baker scale and Harvard Harris, was also not significantly different (two-sided p = 0.147, CI -0.06-0.45), with the Harvard Harris cosmesis differences remaining insignificant across the 3 month, 1 year, and greater than 13 month periods (two-sided p = 0.854, 0.351, 0.468, respectively). The secondary endpoint, toxicity, was not significantly different between the novel and standard PMRT groups across 3 months and 1 year time periods (two-sided p = 0.328, 0.323, respectively). We will also be reporting the analysis for predictive factors related to toxicity, need for corrective surgery and cosmesis.

CONCLUSION

Compared with standard PMRT, the novel technique was not significantly different in rates of reoperation, toxicity and cosmetic outcomes. Better understanding the factors involved in PMRT outcomes for breast cancer patients with implant-based reconstructions will aid in the development of standardized approaches to treating the breast cancer patient population.

A realist review of health passports for Autistic adults

BACKGROUND

Autism is a normal part of cognitive diversity, resulting in communication and sensory processing differences, which can become disabling in a neurotypical world. Autistic people have an increased likelihood of physical and mental co-occurring conditions and die earlier than neurotypical peers. Inaccessible healthcare may contribute to this. Autism Health Passports (AHPs) are paper-based or digital tools which can be used to describe healthcare accessibility needs; they are recommended in UK clinical guidance. However, questions remained as to the theoretical underpinnings and effectiveness of AHPs.

METHODS

We undertook a systematic literature search identifying studies focused on AHPs for adults (aged over 16 years) from five databases. Included literature was subjected to realist evaluation. Data were extracted using a standardised form, developed by the research team, which considered research design, study quality for realist review and the Context, Mechanisms and Outcomes (CMOs) associated with each AHP tool.

FINDINGS

162 unique records were identified, and 13 items were included in the review. Only one item was considered high quality. Contextual factors focused on the inaccessibility of healthcare to Autistic patients and staff lack of confidence and training in supporting Autistic needs. Interventions were heterogeneous, with most sources reporting few details as to how they had been developed. The most frequently included contents were communication preferences. Mechanisms were often not stated or were inferred by the reviewers and lacked specificity. Outcomes were included in four studies and were primarily focused on AHP uptake, rather than Outcomes which measured impact.

CONCLUSION

There is insufficient evidence to conclude that AHPs reduce the health inequalities experienced by Autistic people. Using an AHP tool alone in a healthcare Context that does not meet Autistic needs, without the inclusion of the local Autistic community developing the tool, and a wider intervention to reduce known barriers to health inequality, may mean that AHPs do not trigger any Mechanisms, and thus cannot affect Outcomes.

Implementation frameworks for polypharmacy management within healthcare organisations: a scoping review

BACKGROUND

Several guidelines support polypharmacy management in individual patients. More organisational-level focus is needed on the use of implementation frameworks.

AIM

To characterise the peer reviewed literature on implementation frameworks, focussing on barriers and facilitators to implementation at organisational level in the context of polypharmacy management.

METHOD

A scoping review protocol was devised, supporting retrieval of studies published in English, reporting from any sector of practice. Medline, International Pharmaceutical Abstracts, Cumulative Index of Nursing and Allied Health Literature and Business Source Complete were searched to January 2022 using Medical Subject Headings including: 'polypharmacy', 'deprescriptions', 'strategic planning' and 'organizational innovation'. A narrative approach to data synthesis was applied. Searching, data extraction and synthesis were undertaken independently by two reviewers.

RESULTS

After screening 797 records eight papers remained. Two were descriptive outlining details of specific initiatives, six used qualitative methods to explore determinants for implementation including barriers and enablers. Organisation level barriers included: poor organisational culture with a lack of sense of urgency and national plans, resource availability and communication issues including patient information and at transitions of care. Organisational facilitators included availability of government funding and regulatory environment promoting patient safety, a national emphasis on quality of care for older adults, co-ordinated national efforts and local evidence.

CONCLUSION

Limited literature focusses on the use of implementation frameworks at organisational levels. This review highlights the need for further work on implementation frameworks in this context to help achieve effective organisational change.

Breastfeeding sick children in hospital: Exploring the experiences of mothers in UK paediatric wards

There is a paucity of literature exploring the challenges of breastfeeding sick children in hospital. Previous research has focused on single conditions and hospitals which limits understanding of the challenges in this population. Although evidence suggests that current lactation training in paediatrics is often inadequate, it is unclear where the specific training gaps are. This qualitative interview study of UK mothers aimed to explore the challenges of breastfeeding sick infants and children on a paediatric ward or paediatric intensive care unit. From 504 eligible respondents, a sample of 30 mothers of children aged 2-36 months with various conditions and demographic backgrounds was purposively chosen, and a reflexive thematic analysis undertaken. The study identified previously unreported impacts such as complex fluid needs, iatrogenic withdrawal, neurological irritability and changes to breastfeeding behaviour. Mothers described breastfeeding as emotionally and immunologically meaningful. There were many complex psychological challenges such as guilt, disempowerment, and trauma. Wider struggles such as staff resistance to bedsharing, inaccurate breastfeeding information, lack of food and inadequate breast pump provision made breastfeeding more challenging. There are numerous challenges related to breastfeeding and responsively parenting sick children in paediatrics, and these also impacted maternal mental health. Staff skill and knowledge gaps were widespread, and the clinical environment was not always conducive to supporting breastfeeding. This study highlights strengths in clinical care and provides insight into what measures are perceived as supportive by mothers. It also highlights areas for improvement, which may inform more nuanced paediatric breastfeeding standards and training.

Breastfeeding in the pandemic: A qualitative analysis of breastfeeding experiences among mothers from Canada and the United Kingdom

BACKGROUND

Previous research shows that the COVID-19 pandemic resulted in both barriers and facilitators to breastfeeding. However, little research has looked specifically at first-time mothers' experiences of breastfeeding during the pandemic or compared experiences of mothers living in different countries.

AIM

This research explores mothers' breastfeeding experiences to describe how the COVID-19 pandemic has affected breastfeeding journeys in Canada and the United Kingdom.

METHODS

Ten semi-structured online interviews were undertaken with first-time mothers who breastfed their baby at least once during the COVID-19 pandemic and are living in Canada or the United Kingdom. Interview transcripts were coded inductively using thematic analysis.

FINDINGS

One overarching theme (all on mother) and four sub-themes were identified: 1) accessing and advocating for health care, 2) social support, 3) becoming a mother in isolation, and 4) breastfeeding baby. Similar themes were constructed for both countries.

DISCUSSION

Mothers reported that diminished health care and social support created challenges in their breastfeeding journey. Many mothers reported receiving virtual breastfeeding support, which was largely experienced as unhelpful. Some mothers reported fewer distractions from visitors and more one-on-one time with their infant, which helped them to establish breastfeeding and a strong mother-infant bond.

CONCLUSION

In both Canada and the United Kingdom, new mothers need consistent, reliable health care and social support when breastfeeding. This study supports the need to protect breastfeeding support in the midst of a global emergency and beyond to ensure positive breastfeeding experiences for both mother and baby.

Who moves in vulnerable Caribbean neighborhoods? Positive deviance for physical activity: Findings from the Jamaica health and Lifestyle Survey 2017 (JHLS III)

Decreased physical activity (PA) has been associated with residents living in neighborhoods perceived as being disordered or having high crime levels. What is unknown are the characteristics of individuals who engage in moderate to vigorous levels of PA (MVPA) despite living in these vulnerable neighborhoods, or who may be referred to as positive deviants (PD). We examined the factors associated with PD for PA among Jamaicans. Between 2016 and 2017 the Jamaica Health and Lifestyle Survey, a cross-sectional nationally representative survey (n = 2807), was conducted on individuals aged 15 years and older. Regression analyses were performed to identify associations with PD, defined using engagement in MVPA among persons living in vulnerable neighborhoods (N = 1710). Being female (odds ratio [OR]a = 0.64 (0.48, 0.86); p = 0.003), obese while living in an urban area (ORa = 0.39; 95 % CI = 0.26, 0.59; p < 0.0001), unemployed (ORa = 0.53; 95 % CI = 0.39, 0.73; p < 0.0001), or a student (ORa = 0.62; 95 % CI = 0.39, 0.98); p = 0.041) was associated with a significantly lower likelihood of PD, while having a personal medical history of at least one chronic disease significantly increased likelihood (ORa = 1.43; 95 % CI = 1.08, 1.90; p = 0.014). Taking a PD approach may be one angle to consider in trying to determine what is working and for whom, so that this may be harnessed in policy, prevention and intervention programming to increase PA.

Identities of women who have an autoimmune rheumatic disease [ARD] during pregnancy planning, pregnancy and early parenting: A qualitative study

OBJECTIVE

Women of reproductive age who have autoimmune rheumatic diseases [ARDs] have expressed a need to be better supported with making decisions about pregnancy. Women with ARDs want their motherhood identities and associated preferences to be taken into account in decisions about their healthcare. The aim of this study was to explore the interplay between illness and motherhood identities of women with ARDs during preconception decision making.

METHODS

Timeline-facilitated qualitative interviews with women diagnosed with an ARD [18-49 years old]. Participants were purposively sampled based on the following three criteria: thinking about getting pregnant, currently pregnant, or had young children. Interviews were thematically analysed.

RESULTS

Twenty-two women were interviewed face-to-face [N = 6] or over the telephone [N = 16]. Interview length ranged from 20 minutes to 70 minutes, with a mean length of 48 minutes. Three main themes were identified: prioritisation, discrepancy, and trade-off. Difficulties in balancing multiple identities in healthcare encounters were reported. Women used 'self-guides' as a reference for priority setting in a dynamic process that shifted as their level of disease activity altered and as their motherhood identity became more or less of a focus at a given point in time. Women's illness and motherhood identities did not present in isolation but were intertwined.

CONCLUSIONS

Findings highlight the need for holistic person-centred care that supports women with the complex and emotive decisions relating to preconception decision-making. In practice, health professionals need to consider women's multiple and sometimes conflicting identities, and include both their condition and family associated goals and values within healthcare communication.

Views and experience of breastfeeding in public: A qualitative systematic review

Breastfeeding rates in many Global North countries are low. Qualitative research highlights that breastfeeding in public is a particular challenge, despite mothers often having the legal right to do so. To identify barriers and facilitators, we systematically searched the qualitative research from Organisation for Economic Co-operation and Development countries relating to breastfeeding in public spaces from 2007 to 2021. Data were analysed using the Thematic Synthesis technique. The review was registered with PROSPERO (registration number: CRD42017081504). Database searching identified 3570 unique records. In total, 74 papers, theses, or book chapters, relating to 71 studies, were included, accounting for over 17,000 mothers. Overall, data quality was high. Our analysis identified that five core factors influenced mothers' thought processes and their breastfeeding in public behaviour: legal system; structural (in)equality; knowledge; beliefs and the social environment. Macro-level factors relating to legislation and inequality urgently require redress if breastfeeding rates are to be increased. Widespread culture change is also required to enhance knowledge, change hostile beliefs and thus the social environment in which mother/infant dyads exist. In particular, the sexualisation of breasts, disgust narratives and lack of exposure among observers to baby-led infant feeding patterns resulted in beliefs which created a stigmatising environment. In this context, many mothers felt unable to breastfeed in public; those who breastfed outside the home were usually highly self-aware, attempting to reduce their exposure to conflict. Evidence-based theoretically informed interventions to remove barriers to breastfeeding in public are urgently required.

Search for Subsolar-Mass Binaries in the First Half of Advanced LIGO's and Advanced Virgo's Third Observing Run

We report on a search for compact binary coalescences where at least one binary component has a mass between 0.2  M_{⊙} and 1.0  M_{⊙} in Advanced LIGO and Advanced Virgo data collected between 1 April 2019 1500 UTC and 1 October 2019 1500 UTC. We extend our previous analyses in two main ways: we include data from the Virgo detector and we allow for more unequal mass systems, with mass ratio q≥0.1. We do not report any gravitational-wave candidates. The most significant trigger has a false alarm rate of 0.14  yr^{-1}. This implies an upper limit on the merger rate of subsolar binaries in the range [220-24200]  Gpc^{-3} yr^{-1}, depending on the chirp mass of the binary. We use this upper limit to derive astrophysical constraints on two phenomenological models that could produce subsolar-mass compact objects. One is an isotropic distribution of equal-mass primordial black holes. Using this model, we find that the fraction of dark matter in primordial black holes in the mass range 0.2  M_{⊙}<m_{PBH}<1.0  M_{⊙} is f_{PBH}≡Ω_{PBH}/Ω_{DM}≲6%. This improves existing constraints on primordial black hole abundance by a factor of ∼3. The other is a dissipative dark matter model, in which fermionic dark matter can collapse and form black holes. The upper limit on the fraction of dark matter black holes depends on the minimum mass of the black holes that can be formed: the most constraining result is obtained at M_{min}=1  M_{⊙}, where f_{DBH}≡Ω_{DBH}/Ω_{DM}≲0.003%. These are the first constraints placed on dissipative dark models by subsolar-mass analyses.

Scintillation light detection in the 6-m drift-length ProtoDUNE Dual Phase liquid argon TPC

DUNE is a dual-site experiment for long-baseline neutrino oscillation studies, neutrino astrophysics and nucleon decay searches. ProtoDUNE Dual Phase (DP) is a 6  ×  6  ×  6 m 3 liquid argon time-projection-chamber (LArTPC) that recorded cosmic-muon data at the CERN Neutrino Platform in 2019-2020 as a prototype of the DUNE Far Detector. Charged particles propagating through the LArTPC produce ionization and scintillation light. The scintillation light signal in these detectors can provide the trigger for non-beam events. In addition, it adds precise timing capabilities and improves the calorimetry measurements. In ProtoDUNE-DP, scintillation and electroluminescence light produced by cosmic muons in the LArTPC is collected by photomultiplier tubes placed up to 7 m away from the ionizing track. In this paper, the ProtoDUNE-DP photon detection system performance is evaluated with a particular focus on the different wavelength shifters, such as PEN and TPB, and the use of Xe-doped LAr, considering its future use in giant LArTPCs. The scintillation light production and propagation processes are analyzed and a comparison of simulation to data is performed, improving understanding of the liquid argon properties.

Presentation, clinical course and complications in trauma patients with concomitant COVID-19 infection

BACKGROUND

This study investigated the impact of COVID-19 infection on hospitalized trauma patients.

METHODS

A retrospective review of hospitalized trauma patients at a level I trauma center was performed from March-December 2020. Data pertaining to patient demographics, presentation and hospital course was compared between COVID positive and negative trauma patients.

RESULTS

There were 4,912 patients and 179 (3.64%) were COVID-19 positive. Demographics and clinical presentation did not differ significantly between those with and without concomitant COVID-19. However, COVID positive trauma patients had higher rates of acute kidney injury (p = 0.016), sepsis (p = 0.016), unplanned intubation (p = 0.002) and unplanned return to the ICU (p = 0.01). The COVID positive cohort also had longer hospital stays (p < 0.01) with no significant difference in mortality.

CONCLUSIONS

In the setting of an ongoing pandemic, awareness of the complications COVID positive trauma patients are predisposed to is important for providers.

Autistic women's views and experiences of infant feeding: A systematic review of qualitative evidence

Low breastfeeding rates are driven by multiple bio-psycho-social factors. Experience of breastfeeding is known to differ by maternal demographic factors (age, education and ethnicity) but there is less recognition of factors such as neurodivergence. This review, prospectively registered with PROSPERO (registration number: CRD42021271465), systematically identified qualitative research, commentaries and personal accounts related to Autistic mothers and infant feeding. Database searching identified 1225 records, with thematic synthesis undertaken on 22 (eight peer-reviewed studies and 14 grey literature) pieces. Our analysis identified that maternity and infant feeding services were built on a lack of understanding of Autistic needs, and were often inaccessible at a time when Autistic mothers already felt a loss of control and lack of social support. Specifically relating to breastfeeding, knowledge and determination were often high, and a minority of mothers reported positive breastfeeding experiences. However, sensory challenges, pain and interoceptive differences (exacerbated by a lack of support) made breastfeeding impossible for some. Infant formula was viewed as second-best to breastmilk, but a minority of mothers found the ritual of preparing bottles of formula positive. There is an urgent need for maternity and infant feeding services to accommodate the needs of Autistic mothers, including service design and staff training.

Development and implementation of strategic frameworks for polypharmacy management in healthcare organisations: a scoping review

Introduction

‘Polypharmacy management’ (PM) guidelines exist (1) but there are challenges to implementation and WHO recommends theory-based organisational change strategies to address this (2).

Aim

To identify current evidence base around the development and implementation of strategic frameworks for polypharmacy management in healthcare organisations.

Methods

The Arksey and O’Malley framework and the PRISMA Scoping Reviews extension were used. Databases (Medline, IPA, CINAHL and Business Source Complete) were searched to December 2020. After title and abstract screening full text articles were reviewed. Search, data extraction and eligibility criteria were defined (table). Included studies were charted to collate extracted information and a descriptive narrative approach to data synthesis was taken. All steps involved independent checks by two team members with disagreement mediation by a third.

Results

Initially 702 records were identified after removal of duplicates, 632 of these were excluded after screening leaving 70 papers. A further 63 of these 70 papers were excluded after full text review. The seven papers remaining met the eligibility criteria fully and showed: despite wide availability of polypharmacy guidelines in the West, particularly the UK and European Union, there is limited evidence on the strategic development and implementation of PM frameworks. The main characteristics of strategic approaches used included: Kotter’s eight step process for organisational change, theoretical domains framework to identify individual behavioural determinants, and a community-based medication management intervention. Reported barriers were: lack of data to create a sense of urgency, lack of a national plan for implementation, monitoring and evaluation, poor coordination of care, lack of time for staff, unclear allocation of tasks and responsibilities and lack of training. Organisational level facilitators included: government funding streams and strict regulatory environment, national emphasis on quality and presence of contextual evidence.

Conclusion

Despite PM guidance this review shows limited evidence on development of theory based strategic frameworks for organisational change. Evidence was from Western contexts only. A strength of this work is that it searched internationally but was limited by exclusion of grey literature. Further work is required on theory based strategic organisational change in PM particularly in contexts out with the Western world.

EP.TU.660The rate of interval colorectal cancer within 5 years of a negative colonoscopy at a district general hospital

Aims

Interval colorectal cancer is defined as cancer that has developed within a short interval of a diagnostic test that did not detect a cancer. Many authors define this interval as five years, though more complex definitions of interval cancer have been proposed. Our aim was to determine what percentage of colorectal cancers diagnosed at our hospital had a negative colonoscopy within the 5 years prior to their diagnosis.

Methods

We obtained details of all colorectal cancers diagnosed between 2017-2019 at our department. We then surveyed the endoscopy system to detect the patients who had a negative colonoscopy within the 5 years prior to their diagnosis, to calculate what percentage of cancers diagnosed within that period were interval cancers.

Results

Between 2017-2019, 539 patients were diagnosed with colorectal cancer. Age at diagnosis varied widely from 21 to 107, and 310 (57.5%) of patients were male. Seventeen patients had a negative colonoscopy within 5 years (though two of these were planned repeat procedures within a few months of the index ‘negative’ colonoscopy). We can therefore calculate the rate of interval cancer at 3.1% between 2017-2019.

Conclusions

The aetiology of interval colorectal cancer has been attributed to patient/tumour factors (right colon and female sex) and technical factors (adenoma detection and caecal intubation rate). Though the rate of interval cancer at our department seems pleasingly low compared to the literature, we plan to investigate the risk factors that might be at play: are biological factors to blame or can our endoscopy service be improved?

Constraints on Cosmic Strings Using Data from the Third Advanced LIGO-Virgo Observing Run

We search for gravitational-wave signals produced by cosmic strings in the Advanced LIGO and Virgo full O3 dataset. Search results are presented for gravitational waves produced by cosmic string loop features such as cusps, kinks, and, for the first time, kink-kink collisions. A template-based search for short-duration transient signals does not yield a detection. We also use the stochastic gravitational-wave background energy density upper limits derived from the O3 data to constrain the cosmic string tension Gμ as a function of the number of kinks, or the number of cusps, for two cosmic string loop distribution models. Additionally, we develop and test a third model that interpolates between these two models. Our results improve upon the previous LIGO-Virgo constraints on Gμ by 1 to 2 orders of magnitude depending on the model that is tested. In particular, for the one-loop distribution model, we set the most competitive constraints to date: Gμ≲4×10^{-15}. In the case of cosmic strings formed at the end of inflation in the context of grand unified theories, these results challenge simple inflationary models.

Breasts and the city: an urban ethnography of infant feeding in public spaces within Cardiff, United Kingdom

BACKGROUND

Internationally, women report challenges breastfeeding in public spaces. This study aimed to investigate the social-spatial aspects of public spaces in one UK city, Cardiff, in order to suggest possible barriers and facilitators to breastfeeding in public spaces.

METHODS

The study observation location guide prioritised places that had been reported as hostile to breastfeeding or breastfeeding friendly in the existing literature. Data were collected between April and September 2018 at various times of day, in several areas of the city, and included transport (n = 4), transport hubs (n = 3), high streets (n = 4), cafes (n = 2), a large city centre shopping complex, comprising of three joined shopping malls and a large city centre department store containing a third café. Low inference field notes were written on an encrypted smart phone and expanded soon after. Data were analysed thematically using deductive codes based on the observation schedule. Additional inductive codes relating to places were added.

RESULTS

Overall, public transport and the city centre were inhospitable environments for those who might need to breastfeed, and even more so for those who need to express breastmilk. The core barriers and facilitators across locations were the availability of appropriate seating coupled with either high privacy or politely unimposing strangers (civil inattention). The one variation to this model arose from the department store café, where civil inattention was not performed and there was low privacy, but breastfeeding occurred anyway.

CONCLUSIONS

This research highlights the physical and social barriers to breastfeeding within one urban city centre in the UK and its associated transport links. It is clear that there is an urgent need for change in urban city centres and public transport if countries are to meet their aims in relation to increasing breastfeeding rates. Interventions will need to be multifaceted, accounting for social norms relating to infant feeding as well as changes to the physical environment, policy and potentially legal change. Further research should be undertaken in other countries to examine the extent to which hostile environments exist, and if correcting these could facilitate breastfeeding and reduce gender-based violence.

Prospects for beyond the Standard Model physics searches at the Deep Underground Neutrino Experiment: DUNE Collaboration

The Deep Underground Neutrino Experiment (DUNE) will be a powerful tool for a variety of physics topics. The high-intensity proton beams provide a large neutrino flux, sampled by a near detector system consisting of a combination of capable precision detectors, and by the massive far detector system located deep underground. This configuration sets up DUNE as a machine for discovery, as it enables opportunities not only to perform precision neutrino measurements that may uncover deviations from the present three-flavor mixing paradigm, but also to discover new particles and unveil new interactions and symmetries beyond those predicted in the Standard Model (SM). Of the many potential beyond the Standard Model (BSM) topics DUNE will probe, this paper presents a selection of studies quantifying DUNE's sensitivities to sterile neutrino mixing, heavy neutral leptons, non-standard interactions, CPT symmetry violation, Lorentz invariance violation, neutrino trident production, dark matter from both beam induced and cosmogenic sources, baryon number violation, and other new physics topics that complement those at high-energy colliders and significantly extend the present reach.

An 'incredible community' or 'disgusting' and 'weird'? Representations of breastmilk sharing in worldwide news media

Breastmilk sharing via the internet has become more popular in recent years, with a resultant increase in media attention. It is actively discouraged by public health bodies in at least three countries. We undertook a qualitative analysis of worldwide English language news media (online newspaper articles and transcripts of television and radio pieces) focusing on peer‐to‐peer breastmilk sharing during a 24‐month period (2015–2016). One hundred eleven news articles were analysed semiotically for positive (n = 49) and negative (n = 90) depictions of breastmilk sharing and the actors involved. Three countries published the majority of the articles: United States (n = 42), United Kingdom (n = 24) and Australia (n = 20). Topics associated with using shared breastmilk included perceived insufficiency, having surgery or taking medication, or the prematurity of the baby. Reports of women who gave and received breastmilk were largely positive although sometimes confused with women who sell breastmilk, who were demonised. The breastmilk itself, however, was considered as potentially contaminated and possibly dangerous; calls for action (n = 33) focused on increasing regulation and safety. Peer‐to‐peer milk sharing and the commercial availability of human milk are activities that occur within social and cultural contexts, and, as such, the ways in which they are represented in the news media reflect the ways in which they are also represented more widely in society. Increased understanding of normal infant feeding practices is needed, alongside guidance on how to better support breastfeeding. News media outlets can facilitate this through reporting risk in line with evidence. Further research should be undertaken to understand the safety of breastmilk sharing and the experience of those who participate.

Letter to the Editor: Healthy for Life: An Innovative and Collaborative Approach to COVID 19 Lockdown in New Zealand

Recently Boreskie and colleagues published an editorial in the Journal of Frailty and Aging on Preventing Frailty Progression During the COVID-19 Pandemic (1). In it they proposed the SAVE programme (Socialization, Adequate nutrition, Vitamin D, Exercise) to prevent frailty. They concluded that creative thinking and concerted efforts would be needed to disseminate health recommendations to maintain the health of pre-frail and frail older adults in unprecedented times, such as those posed by the COVID-19 pandemic.

GW190521: A Binary Black Hole Merger with a Total Mass of 150 M_{⊙}

On May 21, 2019 at 03:02:29 UTC Advanced LIGO and Advanced Virgo observed a short duration gravitational-wave signal, GW190521, with a three-detector network signal-to-noise ratio of 14.7, and an estimated false-alarm rate of 1 in 4900 yr using a search sensitive to generic transients. If GW190521 is from a quasicircular binary inspiral, then the detected signal is consistent with the merger of two black holes with masses of 85_{-14}^{+21}  M_{⊙} and 66_{-18}^{+17}  M_{⊙} (90% credible intervals). We infer that the primary black hole mass lies within the gap produced by (pulsational) pair-instability supernova processes, with only a 0.32% probability of being below 65  M_{⊙}. We calculate the mass of the remnant to be 142_{-16}^{+28}  M_{⊙}, which can be considered an intermediate mass black hole (IMBH). The luminosity distance of the source is 5.3_{-2.6}^{+2.4}  Gpc, corresponding to a redshift of 0.82_{-0.34}^{+0.28}. The inferred rate of mergers similar to GW190521 is 0.13_{-0.11}^{+0.30}  Gpc^{-3} yr^{-1}.

Rainfall triggers more deep-seated landslides than Cascadia earthquakes in the Oregon Coast Range, USA

The coastal Pacific Northwest USA hosts thousands of deep-seated landslides. Historic landslides have primarily been triggered by rainfall, but the region is also prone to large earthquakes on the 1100-km-long Cascadia Subduction Zone megathrust. Little is known about the number of landslides triggered by these earthquakes because the last magnitude 9 rupture occurred in 1700 CE. Here, we map 9938 deep-seated bedrock landslides in the Oregon Coast Range and use surface roughness dating to estimate that past earthquakes triggered fewer than half of the landslides in the past 1000 years. We find landslide frequency increases with mean annual precipitation but not with modeled peak ground acceleration or proximity to the megathrust. Our results agree with findings about other recent subduction zone earthquakes where relatively few deep-seated landslides were mapped and suggest that despite proximity to the megathrust, most deep-seated landslides in the Oregon Coast Range were triggered by rainfall.

Perioperative intravenous contrast administration and the incidence of acute kidney injury after major gastrointestinal surgery: prospective, multicentre cohort study

BACKGROUND

This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery.

METHODS

This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery.

RESULTS

A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498).

CONCLUSION

There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Using Visual Timelines in Telephone Interviews: Reflections and Lessons Learned From the Star Family Study

Visual timeline methods have been used as part of face-to-face qualitative interviewing with vulnerable populations to uncover the intricacies of lived experiences, but little is known about whether visual timelines can be effectively used in telephone interviews. In this article, we reflect on the process of using visual timelines in 16 telephone interviews with women as part of the "STarting a family when you have an Autoimmune Rheumatic disease" study (STAR Family Study). The visual timeline method was used to empower women to organize and share their narratives about the sensitive and complex topic of starting a family. We conducted a thematic analysis of the audio-recorded interview data, using researchers' field notes and reflections to provide context for our understanding of the benefits of using timelines and to understand the process of using visual timelines during telephone interviews. Resource packs were sent to women before study participation; 11 of the 16 women completed a version of the timeline activity. Six themes were identified in the methodological data analysis: (1) use and adaptation of the timeline tool, (2) timeline exchange, (3) framing the interview: emphasizing that women are in control, (4) jumping straight in, (5) taking a lead, and (6) disclosing personal and sensitive experiences. The use of visual timelines facilitated interviewee control and elicited rich narratives of participants' experiences in telephone interviews. Women created their visual timelines autonomously and retained ownership of their timeline data; these features of the data generation process need to be considered when using visual timelines in telephone rather than face-to-face interviews. Use of visual methods within telephone interviews is feasible, can generate rich data, and should be further explored in a wider range of settings.

Prospects for observing and localizing gravitational-wave transients with Advanced LIGO, Advanced Virgo and KAGRA

We present our current best estimate of the plausible observing scenarios for the Advanced LIGO, Advanced Virgo and KAGRA gravitational-wave detectors over the next several years, with the intention of providing information to facilitate planning for multi-messenger astronomy with gravitational waves. We estimate the sensitivity of the network to transient gravitational-wave signals for the third (O3), fourth (O4) and fifth observing (O5) runs, including the planned upgrades of the Advanced LIGO and Advanced Virgo detectors. We study the capability of the network to determine the sky location of the source for gravitational-wave signals from the inspiral of binary systems of compact objects, that is binary neutron star, neutron star-black hole, and binary black hole systems. The ability to localize the sources is given as a sky-area probability, luminosity distance, and comoving volume. The median sky localization area (90% credible region) is expected to be a few hundreds of square degrees for all types of binary systems during O3 with the Advanced LIGO and Virgo (HLV) network. The median sky localization area will improve to a few tens of square degrees during O4 with the Advanced LIGO, Virgo, and KAGRA (HLVK) network. During O3, the median localization volume (90% credible region) is expected to be on the order of 10 5 , 10 6 , 10 7 Mpc 3 for binary neutron star, neutron star-black hole, and binary black hole systems, respectively. The localization volume in O4 is expected to be about a factor two smaller than in O3. We predict a detection count of 1 - 1 + 12 ( 10 - 10 + 52 ) for binary neutron star mergers, of 0 - 0 + 19 ( 1 - 1 + 91 ) for neutron star-black hole mergers, and 17 - 11 + 22 ( 79 - 44 + 89 ) for binary black hole mergers in a one-calendar-year observing run of the HLV network during O3 (HLVK network during O4). We evaluate sensitivity and localization expectations for unmodeled signal searches, including the search for intermediate mass black hole binary mergers.

Search for Subsolar Mass Ultracompact Binaries in Advanced LIGO's Second Observing Run

We present a search for subsolar mass ultracompact objects in data obtained during Advanced LIGO's second observing run. In contrast to a previous search of Advanced LIGO data from the first observing run, this search includes the effects of component spin on the gravitational waveform. We identify no viable gravitational-wave candidates consistent with subsolar mass ultracompact binaries with at least one component between 0.2  M_{⊙}-1.0  M_{⊙}. We use the null result to constrain the binary merger rate of (0.2  M_{⊙}, 0.2  M_{⊙}) binaries to be less than 3.7×10^{5}  Gpc^{-3} yr^{-1} and the binary merger rate of (1.0  M_{⊙}, 1.0  M_{⊙}) binaries to be less than 5.2×10^{3}  Gpc^{-3} yr^{-1}. Subsolar mass ultracompact objects are not expected to form via known stellar evolution channels, though it has been suggested that primordial density fluctuations or particle dark matter with cooling mechanisms and/or nuclear interactions could form black holes with subsolar masses. Assuming a particular primordial black hole (PBH) formation model, we constrain a population of merging 0.2  M_{⊙} black holes to account for less than 16% of the dark matter density and a population of merging 1.0  M_{⊙} black holes to account for less than 2% of the dark matter density. We discuss how constraints on the merger rate and dark matter fraction may be extended to arbitrary black hole population models that predict subsolar mass binaries.

"Nobody knows, or seems to know how rheumatology and breastfeeding works": Women's experiences of breastfeeding whilst managing a long-term limiting condition - A qualitative visual methods study

Background

Only around 1% of babies in the UK are breastfed exclusively until six months of age as recommended by the World Health Organisation. One in ten women who have recently given birth in the UK have a long-term illness and they are at increased risk of stopping breastfeeding early. We considered women with autoimmune rheumatic diseases as an exemplar group of long term illnesses, to explore the barriers and enablers to breastfeeding

Aim

To understand the experiences of infant feeding among women with autoimmune rheumatic diseases and to identify potential barriers and enablers.

Design

Qualitative visual timeline-facilitated interviews.

Participants and setting

128 women with autoimmune rheumatic diseases who were considering pregnancy, pregnant, or had young children took part in an online survey as part of the STAR Family Study. Of these, 13 women who had children were purposefully sampled to be interviewed. Interviews took place in person or on the telephone. Timeline-facilitated interviews were used to focus on lived experiences and topics important to the women, including early parenting. We conducted a focused thematic analysis of women's lived experiences of infant feeding.

Results

Three main themes were identified in relation to breastfeeding: lack of information about medication safety, lack of support in decision-making and maintaining breastfeeding, and maternal guilt.

Conclusions

Women with autoimmune rheumatic diseases found it difficult to access the information they needed about medications to make informed decisions about breastfeeding. They often also felt pressurised into breastfeeding and experienced feelings of guilt if they were unable, or did not wish to breastfeed. Tailored interventions are required that adopt a non-judgmental and person-centred approach to support decision-making in regard to infant feeding, providing women with information that can best enable them to make infant feeding choices.

Tests of General Relativity with GW170817

The recent discovery by Advanced LIGO and Advanced Virgo of a gravitational wave signal from a binary neutron star inspiral has enabled tests of general relativity (GR) with this new type of source. This source, for the first time, permits tests of strong-field dynamics of compact binaries in the presence of matter. In this Letter, we place constraints on the dipole radiation and possible deviations from GR in the post-Newtonian coefficients that govern the inspiral regime. Bounds on modified dispersion of gravitational waves are obtained; in combination with information from the observed electromagnetic counterpart we can also constrain effects due to large extra dimensions. Finally, the polarization content of the gravitational wave signal is studied. The results of all tests performed here show good agreement with GR.

Common cortical areas involved in both auditory and visual imageries for novel stimuli

We examine cross-modality commonalities in visual and auditory imageries during fMRI scanning in a sample of healthy young adults. In a visual task combining viewed and imagined stimuli, 28 participants were asked to imagine novel scenes related to the other images, and in a similar auditory task combining heard and imagined stimuli, to imagine novel sentences spoken by individuals they had heard speaking previously. We identified a common set of regions in medial and lateral Brodmann area 6, as well as inferior frontal gyrus (BA 44/45), partially supporting previous meta-analytic results. Comparing individuals with high or low reported imagery ability, we replicated a previous result showing individuals with lower visual imagery ability showed greater activation in the cerebellum, frontal and dorsolateral prefrontal cortex, while there was no relationship with auditory imagery ability in this sample. The emphasis on imagining novel stimuli, rather than familiar or previously experienced stimuli, confirms the role of the supramodal imagery network underlying creative imagery.

Abstract PD6-09: Cost effectiveness of bilateral prophylactic mastectomy with and without different breast reconstruction techniques versus screening in women with high risk of breast cancer in the Canadian Province of Ontario

Purpose: We aimed to investigate the cost-effectiveness of mastectomy with and without different reconstruction for the purpose of determining which strategies represent value for money and identify the most cost-effective technique from the perspective of Ontario's health care system.

Methods: We developed a decision analytic model to project the lifetime clinical and economic consequences of different strategies .The decision model was parameterized using 10-year follow up and cost data from Ontario administrative health databases and Ontario Cancer registry and utility data from secondary Canadian sources. Costs are presented in 2018 Canadian dollars. Future costs and benefits were discounted at 5%.

Results: Compared to organized screening-based strategy, surgical strategies ranged from being more effective and cost-saving and up to being associated with an incremental cost effectiveness ratio (ICER) of $63,010 per quality-adjusted life year (QALY) gained, with BPM with immediate one-stage acellular dermal matrix (ADM)-assisted implant breast reconstruction having the greatest incremental QALY of 1.157 and lowest ICER of $9,615. Incorporating the PBM with one-stage ADM-assisted implant immediate breast reconstruction as the standard surgical strategy in Ontario would result in the largest total annual net gains of 20 QALYs and $ 1.7 million.

Conclusion: The choice of breast reconstruction needs to be decided based on the patient body habitus, general condition and goals . BPM with and without reconstruction is likely both clinically and economically attractive. However ,all other things being equal , BPM with immediate one-stage ADM-assisted implant breast reconstruction is the most cost effective strategy and appears to offer the highest value for money.

Constraining the p-Mode-g-Mode Tidal Instability with GW170817

We analyze the impact of a proposed tidal instability coupling p modes and g modes within neutron stars on GW170817. This nonresonant instability transfers energy from the orbit of the binary to internal modes of the stars, accelerating the gravitational-wave driven inspiral. We model the impact of this instability on the phasing of the gravitational wave signal using three parameters per star: an overall amplitude, a saturation frequency, and a spectral index. Incorporating these additional parameters, we compute the Bayes factor (lnB_{!pg}^{pg}) comparing our p-g model to a standard one. We find that the observed signal is consistent with waveform models that neglect p-g effects, with lnB_{!pg}^{pg}=0.03_{-0.58}^{+0.70} (maximum a posteriori and 90% credible region). By injecting simulated signals that do not include p-g effects and recovering them with the p-g model, we show that there is a ≃50% probability of obtaining similar lnB_{!pg}^{pg} even when p-g effects are absent. We find that the p-g amplitude for 1.4  M_{⊙} neutron stars is constrained to less than a few tenths of the theoretical maximum, with maxima a posteriori near one-tenth this maximum and p-g saturation frequency ∼70  Hz. This suggests that there are less than a few hundred excited modes, assuming they all saturate by wave breaking. For comparison, theoretical upper bounds suggest ≲10^{3} modes saturate by wave breaking. Thus, the measured constraints only rule out extreme values of the p-g parameters. They also imply that the instability dissipates ≲10^{51}  erg over the entire inspiral, i.e., less than a few percent of the energy radiated as gravitational waves.
