Using Online Photovoice to Explore Food Decisions of Families on Low Income: Lessons Learnt During the COVID-19 Pandemic

The method of photovoice has been previously used to effectively engage with socioeconomically disadvantaged groups and explore their eating behaviours. In this methodological article, we draw on our experiences from using photovoice through online interviews with families on low income about their food decisions. A purposive recruitment approach targeted parents of children 2-17 years old who lived on a tight budget across the island of Ireland. Participants provided demographic information and were invited to take photographs of food-related decisions and activities for 1 week during the COVID-19 lockdown. The photographs were then discussed through an online communication platform to generate qualitative data. A total of 28 parents participated in the photo-elicited interviews and shared a total of 642 photographs of factors that influenced their food decisions. Following the interviews, the researchers documented their reflections which focused on (1) participants' engagement with the online photo-elicitation and (2) practical aspects around participant consent and data safety. The participants in our study engaged well with the online photovoice method and shared a variety of photos which provided ample material to facilitate the conversations around their food environment and its impact on their food decisions. Our experiences can provide novel insights into using photovoice in a virtual environment and useful considerations around ethics and data collection for researchers who work with socioeconomically disadvantaged groups. Photo-elicited interviews offer an engaging and flexible data collection technique that can highlight issues informing future priorities of healthcare policy.

Bridging the gap between pregnancy loss research and policy and practice: insights from a qualitative survey with knowledge users

BACKGROUND

The loss of a pregnancy or the death of baby around the time of their birth can have profound impacts on parents, families and staff involved. There is much opportunity to enhance the systematic uptake of evidence-based interventions to enhance service provision, lived experiences and outcomes. Challenges exist to translating pregnancy loss research evidence into policy and practice, however. Pregnancy loss remains a neglected area of research and resourcing and is steeped in stigma. While barriers and facilitators to the use of research evidence by decision-makers in public health and health services are well documented, we aimed to better understand the factors that influence the translation of pregnancy loss research into practice and policy.

METHODS

We conducted a qualitative online survey of pregnancy loss research knowledge users in Ireland, identified through our clinical and academic networks, between January and March 2022. The survey comprised ten questions, with three closed questions, informed by the Knowledge Translation Planning Template©. Questions included who could benefit from pregnancy loss research, perceived barriers and facilitators to the use of research evidence and preferred knowledge translation strategies. We analysed data using reflexive thematic analysis.

RESULTS

We included data from 46 participants in our analysis, from which we generated two central themes. The first-'End the silence; stigma and inequality around pregnancy loss to enhance awareness and understanding, public health and services and supports'-addresses issues related to the stigma, sensitivities and silence, lack of awareness and understanding, and lack of relevance or priority afforded to pregnancy loss. The second theme-'Use a range of tailored, accessible approaches to engage a large, diverse range of knowledge users'-highlights the need to use relevant, accessible, and engaging information, resources or materials in knowledge translation efforts, and a variety of tailored approaches to suit different audiences, including materials, workshops/webinars, media, knowledge brokers and champions or opinion leaders.

CONCLUSIONS

Our analysis provides rich insights into the barriers and facilitators to knowledge translation in the field of pregnancy loss research. We identified key strategies that can be used to inform knowledge translation planning in Ireland, and which have international applicability.

Exploring the world of food with families: perspectives of low-income families on factors influencing their food choices

OBJECTIVE

The aim of this study was to investigate the social and environmental factors involved in the food decision-making processes of families living on lower incomes on the Island of Ireland.

DESIGN

A qualitative design was employed for this study, using photovoice and creative mapping methods. Parents were requested to take photos and draw maps of their food environments. Interviews were then conducted with parents, using the materials produced by parents as a cue to discuss their food environments, influences and decision-making processes around food choices.

SETTING

The participants were interviewed online via Microsoft Teams.

PARTICIPANTS

The participants were parents or guardians of children between the ages of 2 and 18 who self-defined as 'living on a tight budget'.

RESULTS

Twenty-eight participants were recruited and interviewed for this study, including twelve parents in Northern Ireland and sixteen in the Republic of Ireland. The findings were mapped on to Bronfenbrenner's Ecological Systems Theory and showed that multiple, overlapping and intersecting factors at the individual, micro-, meso-, exo-, macro- and chrono-system were implicated in family food choices. Upstream factors in particular, including structural, policy and commercial determinants, appear to be significant drivers of behaviour.

CONCLUSIONS

While the findings suggest that a complex range of factors are involved in family food choices, it is clear that policy measures and regulations are needed to stave off the impacts of rising social inequality and food poverty. Health promoters should strive to find non-stigmatising interventions to bridge the nutritional divide experienced by lower-income families.

Recurrent miscarriage and infertility: a national service evaluation

The appropriate clinical care of women/couples with infertility experiencing recurrent miscarriage (RM) is overlooked in international guidelines. We sought to evaluate care provision for women/couples with RM and infertility across public (19 clinics providing RM care, five fertility clinics) and private sectors (nine fertility clinics) using adapted guideline-based key performance indicators (KPIs) for RM. An online survey comprised of multiple-choice/open questions was administered via Qualtrics from November 2021 to February 2022, encompassing: (i) structure of care, (ii) investigations, (iii) treatments, (iv)counselling/supportive care and (v) outcomes. Clinical leads for pregnancy loss and fertility and clinical nurse/midwife specialists within each unit/clinic were invited to participate.The response rate 73% (24/33), varied by provider: Public RM care (18/19; 95%), 2/5 public fertility (40%); private fertility (3/9; 33%). Access to fertility expertise was limited in public RM clinics (39%). While investigations and treatments provided mostly adhered to guidelines, there was uncertainty regarding immunotherapies. Educational needs identified included fertility counselling, informative and supportive care resources. Clinical outcomes were seldom audited (2/22; 9%). Greater engagement with the private sector is required to unify care across sectors and to ensure standardised evidence-based care. Audit and outcomes reporting should be mandated. Lived experience of current care structures should inform service improvements.Impact StatementWhat is already known on this subject? There is a paucity of research into the appropriate clinical care of women/couples with infertility experiencing recurrent miscarriage, with a resulting deficit within international RM guidelines. It is known that RM care is variable and often not in line with guidance.What do the results of this study add? This study demonstrates that while care is largely in line with clinical practice guidelines, there is variation in counselling, imaging and surgical treatments offered. Areas for education identified included fertility counselling and resources for information provision and supportive care. Clinical outcomes were seldom audited.What are the implications of these findings for clinical practice and/or further research? Fertility care must expand to ensure access for women with RM and infertility. Further research exploring barriers and facilitators to the delivery of evidence-based care for women/couples with infertility and RM is required. The lived experiences of service users must inform service improvements.

Microbial composition, rumen fermentation parameters, enteric methane emissions, and lactational performance of phenotypically high and low methane-emitting dairy cows

This experiment was designed to investigate the relation of high and low methane-yield phenotypes with body weight (BW), dry matter intake (DMI), lactation performance, enteric CH4 emissions, and rumen fermentation parameters in lactating dairy cows. A total of 130 multi- and primiparous Holstein cows were screened for enteric CH4 emissions using the GreenFeed system (C-Lock Inc.). Out of these 130 cows, 5 were identified as phenotypically high (HM) and 5 as phenotypically low (LM) CH4 emitters. Cows in the LM group had lower daily enteric CH4 emissions than cows in the HM group (on average 346 vs. 439 g/d, respectively), lower CH4 yield (15.5 vs. 20.4 g of CH4/kg of DMI), and CH4 intensity (13.2 vs. 17.0 g of CH4/ kg of energy-corrected milk yield). Enteric emissions of CO2 and H2 did not differ between HM and LM cows. These 10 cows were blocked by parity, days in milk, and milk production, and were used in a 5-wk randomized complete block design experiment. Milk composition, production, and BW were also not different between LM and HM cows. The concentration of total volatile fatty acids in ruminal contents did not differ between CH4 phenotypes, but LM cows had a lower molar proportion of acetate (57 vs. 62.1%), a higher proportion of propionate (27.5 vs. 21.6%, respectively), and therefore a lower acetate-to-propionate ratio than HM cows. Consistently, the 16S cDNA analysis revealed the abundance of Succinivibrionaceae and unclassified Veillonellaceae to be higher in LM cows compared with HM cows, bacteria that were positively correlated with ruminal propionate concentration. Notably, Succinivibrionaceae trigger the formation of propionate via oxaloacetate pathway from phosphoenolpyruvate via Enzyme Commission: 4.1.1.49, which showed a trend to be higher in LM cows compared with HM cows. Additionally, LM cows possessed fewer transcripts of a gene encoding for methyl-CoM reductase enzyme compared with HM. In this study, low and high CH4-yield cows have similar production performance and milk composition, but total-tract apparent digestibility of organic matter and fiber fractions was lower in the former group of animals.

Interactions Between Nutrition Professionals and Industry: A Scoping Review

BACKGROUND

In recent years, interactions between nutrition professionals (NPs) and the food industry, such as sponsorship arrangements, have raised concerns, particularly as these may negatively impact the trustworthiness and credibility of the nutrition profession. This study aimed to map the literature and identify knowledge gaps regarding interactions between NPs and industry. We sought to examine the nature of such interactions and NPs perspectives about these, as well as the risks and solutions.

METHODS

We conducted a scoping review according to a pre-registered protocol, searching eight electronic databases and grey literature sources in March 2021 to identify documents for inclusion. Two independent reviewers screened citations for inclusion and conducted data extraction. Quantitative and qualitative syntheses were conducted.

RESULTS

We identified 115 documents for analysis, published between 1980 to 2021, with a majority from the United States (n=59, 51%). Only 32% (n=37) were empirical studies. The food industry was the most frequent industry type discussed (n=91, 79%). We identified 32 types of interactions between NPs and industry, such as continuing education provided by industry and sponsorship of professional bodies and health and nutrition organizations. The financial survival of nutrition organizations and continuing education access for NPs were the most frequently cited advantages of industry-NPs interactions. On the other hand, undermining public trust, NPs credibility and public health nutrition recommendations were pointed out as risks of these interactions. Following a code of ethics, policies, or guidelines was the most frequently proposed solution for managing these interactions.

CONCLUSION

Despite the increasing attention given to this issue, few empirical papers have been published to date. There is a need for more research to better and systematically document industry interactions with NPs and the impacts associated with these, as well as more research on effective management strategies.

Screening macroalgae for mitigation of enteric methane in vitro

This study investigated the effects of 67 species of macroalgae on methanogenesis and rumen fermentation in vitro. Specimens were analyzed for their effect on ruminal fermentation and microbial community profiles. Incubations were carried out in an automated gas production system for 24-h and macroalgae were tested at 2% (feed dry matter basis) inclusion rate. Methane yield was decreased 99% by Asparagopsis taxiformis (AT) when compared with the control. Colpomenia peregrina also decreased methane yield 14% compared with control; no other species influenced methane yield. Total gas production was decreased 14 and 10% by AT and Sargassum horneri compared with control, respectively. Total volatile fatty acid (VFA) concentration was decreased between 5 and 8% by 3 macroalgae, whereas AT reduced it by 10%. Molar proportion of acetate was decreased 9% by AT, along with an increase in propionate by 14%. Asparagopsis taxiformis also increased butyrate and valerate molar proportions by 7 and 24%, respectively, whereas 3 macroalgae species decreased molar proportion of butyrate 3 to 5%. Vertebrata lanosa increased ammonia concentration, whereas 3 other species decreased it. Inclusion of AT decreased relative abundance of Prevotella, Bacteroidales, Firmicutes and Methanobacteriaceae, whereas Clostridium, Anaerovibrio and Methanobrevibacter were increased. Specific gene activities for Methanosphaera stadtmane and Methanobrevibacter ruminantium were decreased by AT inclusion. In this in vitro study, Asparagopsis taxiformis was most effective in decreasing methane concentration and yield, but also decreased total gas production and VFA concentration which indicates overall inhibition of ruminal fermentation. No other macroalgae were identified as potential mitigants of enteric methane.

'An extra level of kind of torment': Views and experiences of recurrent miscarriage care during the initial phases of COVID-19 in Ireland-A qualitative interview study

INTRODUCTION

Maternity services underwent much change during the COVID-19 pandemic. Research on the impact on miscarriage care and experiences during this time is sparse. Within a national evaluation of recurrent miscarriage care, we qualitatively explored stakeholder views and experiences of recurrent miscarriage services in Ireland. This study describes the impact of the COVID-19 pandemic on those experiences and perceptions of care.

METHODS

People with professional and lived experience of recurrent miscarriage and service engagement were actively involved in this qualitative study from idea generation to analysis and reporting. We recruited women and men with two or more consecutive first-trimester miscarriages, and people involved in the management/delivery of recurrent miscarriage services and supports. We used purposive sampling to ensure that perspectives across disciplinary or lived experience, geographical, and health service administrative areas, were included. We conducted semi-structured interviews, virtually all due to COVID-19 restrictions, between June 2020 and February 2021. These were audio-recorded, and data were transcribed, and subsequently analyzed using reflexive thematic analysis.

RESULTS

We interviewed 42 service providers and 13 women and 7 men with experience of recurrent miscarriage. We actively generated two central themes during data analysis. The first-'Disconnected'-describes how many women navigated miscarriage diagnosis and management and care in subsequent pregnancies alone; many felt that this resulted in increased trauma. At the same time, men struggled with not being present to support their partners and described feeling disconnected. The second theme highlighted 'The perceived dispensability of recurrent miscarriage services and supports'. Some service providers felt that service reduction and redeployment demonstrated a lack of value in the service. Virtual clinics facilitated access to services, but a preference for in-person care was highlighted.

CONCLUSION

Our analysis provides rich insights into the significant impacts that the COVID-19 pandemic has had on the way recurrent miscarriage care is provided and experienced, with important implications for early pregnancy, miscarriage and recurrent miscarriage care. Services have undergone significant changes and, while these may be temporary, how services should be delivered in the future requires consideration, particularly given the deficits in care and care experiences highlighted prepandemic.

Factors that shape recurrent miscarriage care experiences: findings from a national survey

BACKGROUND

Learning what matters to women/couples with recurrent miscarriage (RM) is essential to inform service improvement efforts and future RM care practices. Previous national and international surveys have examined inpatient stays, maternity care, and care experiences around pregnancy loss, but there is little focus on RM care. We aimed to explore the experiences of women and men who have received RM care and identify patient-centred care items linked to overall RM care experience.

METHODS

Between September and November 2021, we invited people who had experienced two or more consecutive first trimester miscarriages and received care for RM in Ireland in the ten-year period prior to participate in a cross-sectional web-based national survey. The survey was purposefully designed and administered via Qualtrics. It included questions on sociodemographics, pregnancy and pregnancy loss history, investigation and treatment for RM, overall RM care experience, and patient-centred care items at various stages of the RM care pathway such as respect for patients' preferences, information and support, the environment, and involvement of partners/family. We analysed data using Stata.

RESULTS

We included 139 participants (97% women, n = 135) in our analysis. Of the 135 women, 79% were aged 35-44 years (n = 106), 24% rated their overall RM care experience as poor (n = 32), 36% said the care they received was much worse than expected (n = 48), and 60% stated health care professionals in different places did not work well together (n = 81). Women were more likely to rate a good care experience if they had a healthcare professional to talk to about their worries/fears for RM investigations (RRR 6.11 [95% CI: 1.41-26.41]), received a treatment plan (n = 70) (RRR 3.71 [95% CI: 1.28-10.71]), and received answers they could understand in a subsequent pregnancy (n = 97) (RRR 8 [95% CI: 0.95-67.13]).

CONCLUSIONS

While overall experience of RM care was poor, we identified areas that could potentially improve people's RM care experiences - which have international relevance - such as information provision, supportive care, communication between healthcare professionals and people with RM, and care coordination between healthcare professionals across care settings.

An examination of care received by women with recurrent miscarriage and infertility against guideline-based key performance indicators

OBJECTIVES

International guidelines for the management of recurrent miscarriage (RM) do not provide detailed guidance for the care of women/couples with concurrent infertility. Research studies concerning the investigation and treatment of RM frequently omit this cohort. The aim of this study was to assess the care of women/couples with infertility attending a RM clinic in a large tertiary unit in the Republic of Ireland.

STUDY DESIGN

We conducted an audit of women with RM and infertility attending our RM clinic from 2008 to 2020 against 110 established guideline-based key performance indicators (KPIs) for RM care, encompassing five categories: structure of care, counselling/supportive care, investigation, treatment and outcomes. Information was gathered from documentation from the RM clinic, hospital laboratory and electronic health records.

RESULTS

We identified 128 women with infertility and RM. Information provision in RM clinics regarding modifiable risk factors (71 %; 91/128) and unexplained RM (53 %; 69/128) could be improved. Most women were investigated in line with KPIs, except for pelvic ultrasound (40 %; 51/128), cytogenetic analysis (27 %; 34/128) and 3D ultrasound (2 %; 2/128). Immunotherapies were seldom prescribed (<1%); however, 98 % (125/128) of women received aspirin, 48 % LMWH (62/128) and 16 % corticosteroids (21/128). Surgical interventions were uncommon (5 %; 6/128)). The subsequent pregnancy rate was 70 % (89/128), with 36 % undergoing artificial reproductive technology (32/89). The livebirth rate was 63 % (56/89); 37 % had a further pregnancy loss (33/89), of which two were second-trimester miscarriages.

CONCLUSIONS

Women with RM and infertility received care largely in line with RM guideline-based KPIs. However, we identified areas for improvement, including the quality of information provision, and access to certain investigations. While guideline-based KPIs allow for internationally applicable and reproducible audit that can direct service improvements, the experiences and needs of service-users are not captured, meriting further qualitative research.

Supratherapeutic dabigatran: a cause of life-threatening haemorrhage

In this case report, we present a rare case of life-threatening gastrointestinal haemorrhage associated with deranged coagulation due to supratherapeutic levels of dabigatran. Dabigatran is a potent, synthetic, reversible non-peptide thrombin inhibitor which is increasingly used for stroke prevention in patients with non-valvular atrial fibrillation. It is generally accepted that dabigatran dosing does not require titration or the monitoring of plasma levels due to its predictable pharmacokinetics and pharmacodynamics. However, this case report challenges this viewpoint while identifying an important knowledge gap in relation to the effect of altered gastrointestinal motility on the absorption of direct oral anticoagulants. Furthermore, it demonstrates the successful use of high-dose idarucizumab in a critical care setting. Idarucizumab is a monoclonal antibody fragment that binds specifically to dabigatran and its metabolites, thereby reversing the anticoagulant effect.

Addressing obstetricians' awareness of compassion, communication, and self-care when caring for families experiencing stillbirth: Evaluation of a novel educational workshop using applied drama techniques

INTRODUCTION

Obstetricians describe feeling shocked and isolated following stillbirth. Few receive adequate training in how to care for bereaved parents or themselves. We developed a novel workshop for trainee obstetricians using applied drama techniques-in collaboration with the National Theatre of Ireland, the national training body for obstetricians and gynaecologists, and patient support groups-to teach obstetricians skills in communication and self-care around the time of stillbirth.

MATERIALS AND METHODS

Five workshops, delivered January-May 2018, are the focus of this evaluation. Senior trainees in Obstetrics attended and completed a post-workshop evaluation questionnaire. Five-point Likert scales were used to assess participants' communication and support skills pre- and post- the workshop, and their views on pre-specified attributes needed when caring for families experiencing stillbirth and aspects of the workshop. Quantitative and qualitative data were analysed using descriptive statistics and content analysis, respectively.

RESULTS

39/59 (66%) workshop participants completed the questionnaires. Most had received no prior training in caring for families experiencing antenatal (31/39, 80%) or intrapartum (34/39, 87%) stillbirth. Following the workshop there was a significant improvement in trainee's level of confidence in breaking bad news, communicating clearly with the family when breaking bad news, recognising the emotional needs of the family, recognising their own emotional responses, and supporting their colleagues. Trainees were positive about the workshop content and delivery; 90% stated they would recommend it to a colleague.

DISCUSSION

Adequate, appropriate, and stimulating education and training in stillbirth care and self-care is clearly needed to improve patient care. Our findings demonstrate that this novel educational workshop using applied drama techniques-developed in collaboration with diverse stakeholders and underpinned by the views of parents and obstetricians who had experience of stillbirth-is an acceptable and appropriate way of training obstetricians in how to care for bereaved parents and/or to engage in self-care.

Reproductive Outcomes Following Recurrent First Trimester Miscarriage: A Retrospective Cohort Study

STUDY QUESTION

What are the subsequent reproductive outcomes (livebirths, miscarriages or other adverse pregnancy outcomes or no further pregnancy) of women with recurrent miscarriage (RM) attending a dedicated clinic?

SUMMARY ANSWER

Of women with RM, 77% had a subsequent pregnancy, and among these pregnancies, the livebirth rate was 63%.

WHAT IS KNOWN ALREADY

RM affects ∼1–3% of women of reproductive age. RM has known associations with advanced maternal age, obesity, diabetes, inherited thrombophilias, thyroid dysfunction, endometriosis and parental balanced translocations. However, ∼ 50% of women or couples will be left without an explanation for their pregnancy loss, even after completing investigations. RM is also associated with secondary infertility and adverse pregnancy outcomes including preterm birth and perinatal death.

STUDY DESIGN, SIZE, DURATION

We undertook a retrospective cohort study to identify subsequent pregnancy outcomes in women with RM, defined as three consecutive first-trimester miscarriages. Women attending the RM clinic at a tertiary university hospital in the Republic of Ireland over 12 years (2008–2020) with a confirmed diagnosis of primary or secondary first-trimester RM were eligible for inclusion. In total, 923 charts were identified for review against the eligibility criteria.

PARTICIPANTS/MATERIALS, SETTING, METHODS

Women with non-consecutive first-trimester miscarriages or ectopic pregnancy were excluded. Epidemiological and clinical information regarding medical history, investigation and management was gathered from paper and electronic medical records. Data were analysed using SPSS (Version 27). Associations between maternal characteristics and outcomes were explored using the χ² test, with significance set at P < 0.05. Multinomial regression analysis was performed using a stepwise approach.

MAIN RESULTS AND THE ROLE OF CHANCE

There were 748 women who were included; 332 (44%) had primary RM and 416 (56%) had secondary RM. The median age was 36 years (range 19–47). Foetal aneuploidy was the most common investigative finding (15%; n = 111/748); 60% had unexplained RM. In addition to supportive care, most women were prescribed aspirin (96%) and folic acid (75%). Of the 748 women, 573 had a subsequent pregnancy (77%) and 359 (48% of all women; 63% of pregnancies) had a livebirth, while 208 had a further pregnancy loss (28% of all women; 36% of pregnancies) and 6 were still pregnant at the end of the study. Women aged 35–39 years were more likely to have a livebirth than no further pregnancy (relative risk ratio (RRR): 2.29 (95% CI: 1.51–5.30)). Women aged 30–34 years were more likely to have a livebirth (RRR: 3.74 (95% CI: 1.80–7.79)) or a miscarriage (RRR: 2.32 (95% CI: 1.07–4.96)) than no further pregnancy. Smokers were less likely to have a livebirth (RRR: 0.37 (95% CI: 0.20–0.69)) or a miscarriage (RRR: 0.45 (95% CI: 0.22–0.90)) than no further pregnancy. Couples with an abnormal parental karyotype were less likely to have a miscarriage than no further pregnancy (RRR: 0.09 (95% CI: 0.01–0.79)). Including successive pregnancies conceived over the study period, the overall livebirth rate was 63% (n = 466/742), but this was reduced to 44% in women aged ≥40 years and 54% in women with infertility.

LIMITATIONS, REASONS FOR CAUTION

This work covers 13 years; however, those included in the later years have a shorter follow-up time. Although electronic health records have improved data availability, data collection in this cohort remains hampered by the absence of a formal booking visit for women presenting with miscarriage and a national miscarriage database or register.

WIDER IMPLICATIONS OF THE FINDINGS

Our findings are largely reassuring as most women with RM and hoping to conceive achieved a livebirth. In addition to older age, smoking and parental balanced translocations were associated with a reduced likelihood of further pregnancy. No investigation or treatment was associated with pregnancy outcome, reiterating the importance of the supportive aspects of care for women and their partners after RM and counselling regarding individual risk factors. This contributes to the limited international data on the investigative findings and treatment of women with RM. The high rate of prescribed medications merits greater scrutiny, in conjunction with other pregnancy outcomes, and reiterates the need for a national guideline on RM.

How we define recurrent miscarriage matters: A qualitative exploration of the views of people with professional or lived experience

BACKGROUND

Recurrent miscarriage (RM) affects 1%-3% of women/couples of reproductive age depending on the definition used, for example, whether 2 or ≥3 miscarriages. Stakeholders' views of how RM is defined have received limited attention to date. A definition reflects the medical evidence and values of a society at the time, and thus warrants ongoing review.

AIM

We aimed to explore the views of couples are offered and men with lived experience of RM, and those involved in the delivery/management of services and supports, on how RM is and/or should be defined.

METHODS

We adopted a qualitative study design, incorporating semi-structured interviews. We used purposive sampling to recruit participants in the Republic of Ireland, ensuring diverse perspectives were included. Women and men with lived experience of ≥2 consecutive first-trimester miscarriages were recruited via health professionals and social media; other participants via the research team's networks. Interviews were audio-recorded, transcribed, pseudo-anonymized and analysed using reflexive thematic analysis.

FINDINGS

We conducted interviews with 42 health professionals/service providers and 13 couples are offered and 7 men with lived experience of RM (June 2020 to February 2021). We generated three interrelated themes from the data: (i) The need for a standardized definition of recurrent miscarriage-Finding a balance between research evidence, individual needs and healthcare resources, (ii) The definition is a route to finding an answer and/or validating women/couples' experience of loss and (iii) Working around the definition-Advocacy and impacts.

CONCLUSION

A nuanced approach to defining RM is warranted, one which is evidence-informed recognizes the individual needs of women/couples, and considers healthcare resources.

The experiences and perceptions of young people and older people living with dementia of participating in intergenerational programmes: A qualitative evidence synthesis

Background

Intergenerational programmes are formal activities bringing different generations together and have been identified as a way to help people living with dementia to stay socially connected. While there is some evidence from individual studies as to their benefits, there is no overall coherent account as to the perceptions and experiences of participants who engage in such programmes. This review synthesises qualitative evidence of the experiences and perceptions of young people and older people living with dementia of participating in such programmes.

Methods

We searched EBSCO CINAHL, OVID Medline, Embase, Ovid PsycINFO, the Web of Science, Epistemonikos and grey literature sources. We used thematic synthesis to analyse and synthesise the evidence in to four themes, with 11 key findings. We assessed our confidence in each of these findings using the GRADE-CERQual (Confidence in the Evidence from Reviews of Qualitative research) approach.

Findings

Our review highlights the potential enjoyment for young people and older people living with dementia when participating in Intergenerational programmes, despite some initial trepidation. These programmes provide an opportunity to establish and develop relationships and for young people to learn about dementia, ageing and how to interact with older people living with dementia. However, it is important to have staff facilitators present to provide reassurance to both groups. It is also important to take the personal preferences of participants into account and to be considerate of noise levels and other aspects of programme delivery that may inhibit engagement.

Conclusion

This is the first qualitative evidence synthesis specifically exploring Intergenerational programmes aimed at older people living with dementia. We provide insights into the perspectives of those who have participated in Intergenerational programmes. It is important to consider these views, together with other evidence of effectiveness, when planning Intergenerational programmes. While our review is limited by a small number of studies from only a few countries, we have moderate to high confidence in our findings. Further research into the development of Intergenerational programmes specifically tailored for people living with dementia is needed. The findings also provide guidance for people planning to deliver or design future Intergenerational programmes.

Training assessment of clinical knowledge and skills in the use of negative pressure wound dressings in cardiac patients

Funding Acknowledgements

Type of funding sources: None.

Objective

An assessment was conducted to analyse the level of improvement impact one can have on clinical knowledge and skills in the use of a novel negative pressure wound dressings in high-risk cardiac patients along with their years of experience following a training program conducted among our cardiac staff.

Methods

In a prospective study involving twenty cardiac nursing staff from December 2020 to June 2021 who voluntarily participated in the study. Their pre and post training assessment of clinical knowledge and skills were assessed using twenty questionnaires. The pre and post training educational knowledge and skills scores were analysed along with their years of clinical experience.

Results

In the six-month period n=20 (100 %) were compliant to the training despite the covid-19 pandemic.

The study group showed an average pre-training score of 10.5% (Knowledge 5.25% and Skills 5.25%)

The average post-training score of84.75% (Knowledge 42.25% and Skills 42.25%)

While comparing the years of clinical experience against the pre and post training scoresSeventeen (n=17/20, 85%) had five to ten years experience compared to three (n-3/20, 15%) with more than 20 years of experience.

Conclusion

Both clinical knowledge and skills can be augmented through regular training members with more than ten years of clinical experience might have an added benefit and their experience could be important to train younger staff members with less clinical experience.

P-427 Pregnancy outcomes following recurrent first-trimester miscarriage: a retrospective cohort study

What are the subsequent pregnancy outcomes (livebirths, miscarriages or other adverse pregnancy outcomes) in a cohort of women with recurrent miscarriage (RM)?

Summary answer

The overall live birth rate in women with RM was 62% (466/748), falling to 44% in women aged &gt;40 and 54% in women with infertility.

What is known already

RM affects approximately 1% of women of reproductive age. RM is recognized as a prognostic indicator for subsequent pregnancies and adverse pregnancy outcomes including ante-partum hemorrhage, diabetes, preterm birth, small for gestational age and perinatal death. While RM has known associations with advanced maternal age, obesity, diabetes, thyroid dysfunction and endometriosis, approximately 50% of women/couples will be left without an explanation for their pregnancy loss, even after completing investigations.

Study design, size, duration

A retrospective cohort study was undertaken to identify subsequent pregnancy outcomes in women with RM, where RM referral criteria are 3 consecutive first-trimester miscarriages. Women attending the pregnancy loss clinic at a tertiary university hospital in the Republic of Ireland over a 12-year period (2008 - 2020) with a confirmed diagnosis of primary or secondary first-trimester RM were eligible for inclusion. In total, 923 charts were identified for review against the eligibility criteria.

Participants/materials, setting, methods

Women with non-consecutive first trimester miscarriages or ectopic pregnancy were excluded. Epidemiological and clinical information was gathered from paper and electronic medical records. Data were analysed descriptively using SPSS (Version 27).

Main results and the role of chance

Of 748 women identified, 332(44%) had primary RM, 416(56%) had secondary RM. The median age was 36(range 19-47) years with 12% aged under 29 and 64% of women aged ≥35. 142(19%) had a history of infertility with 43(5.7%) attending for ART.

12% of women had anti-nuclear antibodies(89/742), 8% had abnormal thyroid function tests(60/742), 4.7% were heterozygous carriers of the Factor V Leiden gene mutation(35/737), 1.5% had positive anti-cardiolipin antibodies(11/733), 2% were carriers of a Prothrombin gene mutation(7/343) and 1% had elevated HbA1c levels(7/742).

Fetal karyotype was recorded in 141 pregnancies, with 111 abnormal results(78%;111/141). Trisomy(T) 16 was most common(17/111; 15%) followed by T21 and T22(n = 14; 13%). Parental karyotyping of 697 sets of parents identified 28 balanced translocations(4%; 28/697).

Prescribed pharmacological treatments included high dose folic acid(75%; n = 548/728), aspirin(96%; 696/726), progesterone (52%; 389/728), tinzaparin(24%; 175/727), prednisolone(4%; 28/726), metformin(2%; 12/727) and hydroxychloroquine(1%; 7/727).

573 women had a subsequent pregnancy (76.6%); 359(62%; 359/573) had a live birth, 190 had a miscarriage(33%) and 18(3%) had an adverse pregnancy outcome such as ectopic pregnancy, stillbirth or second-trimester miscarriage.

Including successive pregnancies over the study period, the overall live birth rate was 62%(466/748), falling to 44% in women aged &gt;40 and 54% in women with infertility.

Limitations, reasons for caution

This work covers a 12-year period, and while the RM clinic staffing is largely unchanged, some changes in management of RM patients has occurred in this time, reflecting up-to-date evidence and greater public awareness. Furthermore, the adoption of an electronic health chart in 2017 may have affected data availability.

Wider implications of the findings

Our findings confirm RM occurs more frequently in women aged &gt;35. Aneuploidy remains a leading cause of miscarriage. Age is a prognostic indicator for livebirth after RM. These findings will facilitate counselling in this cohort. The substantial rates of prescribed medications and infertility in women with RM merit further exploration.

P-393 The care experiences of women and men who have received recurrent miscarriage care in Ireland: a national survey

Study question

What are the care experiences of women and men who have received recurrent miscarriage (RM) care in the Republic of Ireland?

Summary answer

Of the participants, 24% rated a poor experience of RM care (n = 32), while 36% said the care they received was much worse than expected (n = 48).

What is known already

International guidelines suggest that couples who experience RM should be referred for specialist investigations, support and, if possible, treatment. Providing individualised care, respect for women’s opinions, and appropriate clinical information is imperative to those experiencing RM. However, currently, there is no national standard for the management, investigation, or follow-up of those who experience RM in Ireland. Research on patient-centred early pregnancy care concluded that it is essential for healthcare professionals (HCPs) to realise that women undergoing miscarriage experience a significant life event and recommended that future studies explore potential targets for improving RM care and patients’ perspectives.

Study design, size, duration

A cross-sectional study of women and men who have experienced RM was conducted. An anonymous web-based national survey was used to examine the experience of those who have interacted with the maternity services following RM. The survey was distributed online using Qualtrics between September – November 2021. The survey was shared through emails, websites, newsletters, and social media accounts as well as the Pregnancy Loss Research Group and the Miscarriage Association of Ireland among others.

Participants/materials, setting, methods

Women and men over 18 who have experienced two≥ first trimester miscarriages in the last ten years and who have received care for RM in the Republic of Ireland were invited to participate in the survey. The survey was purposefully designed using relevant literature, including questions on key areas such as sociodemographic information, pregnancy and pregnancy loss history, investigation and treatment for RM. Descriptive statistics and subgroup analysis are ongoing using Stata.

Main results and the role of chance

In total, 213 participants completed the survey (some did not experience a consecutive RM or receive care between 2011-2021 (n = 65)). Therefore, 147 participants were eligible (97% female, n = 135). Of the female participants, 79% were aged 35-44 years (n = 106), 95% were white Irish (n = 128) and 84% were married (n = 114). Women were educated, with 38% having postgraduate degrees (n = 53) or a university degree (27%, n = 36). 57% had experienced two consecutive RM (n = 77) and 25% three consecutive RM (n = 34). Of the 135 women, 53% had investigations for RM (n = 71), with 45% having investigations after two RM (n = 32) or 27% after three RM (26). When asked if their HCP did everything to investigate their RM, 49% said no. Of those who had investigations (n = 71), 83% always had confidence and trust in their HCP (n = 59), and 42% felt treated with dignity and respect (n = 30). However, 44% did not have a HCP to talk to about their worries and fears (n = 31). 24% of women rated a poor experience when receiving RM care (n = 32), 36% said the care they received was much worse than expected (n = 48), with 60% of women saying that HCPs in different places did not work well together during their RM care (n = 81).

Limitations, reasons for caution

Despite an open call to recruit women and men, only four men participated. Therefore, further research needs to include strategies to recruit men to provide a complete picture of RM care experiences. There is also the potential for recall bias as some women received care several years ago.

Wider implications of the findings

This study demonstrates that the overall experience for RM care is poor, providing areas for improvements such as communication and better care coordination between HCPs across hospitals/units. These results provide a better understanding of the drivers shaping care experiences to help inform and improve RM care in Ireland.

Outsourcing Transcription: Extending Ethical Considerations in Qualitative Research

Research ethics considerations foreground minimising harm to participants. Whilst increasing attention is being paid to researcher vulnerabilities, little has been written about transcriptionists, who can potentially experience emotional distress and vicarious trauma. In this article, we highlight ethical considerations when outsourcing audio for transcription as part of the RE:CURRENT (REcurrent miscarriage: evaluating CURRENT services) Project. Through qualitative interviews, we explored the perspectives of those involved in the management/delivery of services, and women and men who experienced recurrent miscarriage (N = 62). We put distress protocols in place for participants, researchers and the transcriptionist, and adopted a research team approach with the professional transcriber. The transcriptionist highlighted the isolated nature of the role; how researchers often did not brief her when commissioning work, and how the personal impacts of this work were rarely considered. Researchers and ethics committees should consider ethical responsibilities to 'do no harm' when it comes to transcriptionist wellbeing.

Developing guideline-based key performance indicators for recurrent miscarriage care: lessons from a multi-stage consensus process with a diverse stakeholder group

BACKGROUND

Standardised care pathways tailored to women/couples who experience recurrent miscarriage are needed; however, clinical practice is inconsistent and poorly organised. In this paper, we outline our processes and experiences of developing guideline-based key performance indicators (KPIs) for recurrent miscarriage care with a diverse stakeholder group which will be used to evaluate national services. To date, such exercises have generally only involved clinicians, with the need for greater stakeholder involvement highlighted.

METHODS

Our study involved six stages: (i) identification and synthesis of recommendations for recurrent miscarriage care through a systematic review of clinical practice guidelines; (ii) a two-round modified e-Delphi survey with stakeholders to develop consensus on recommendations and outcomes; (iii) four virtual meetings to develop this consensus further; (iv) development of a list of candidate KPIs; (v) survey to achieve consensus on the final suite of KPIs and a (vi) virtual meeting to agree on the final set of KPIs. Through participatory methods, participants provided feedback on the process of KPI development.

RESULTS

From an initial list of 373 recommendations and 14 outcomes, 110 indicators were prioritised for inclusion in the final suite of KPIs: (i) structure of care (n = 20); (ii) counselling and supportive care (n = 7); (iii) investigations (n = 30); treatment (n = 34); outcomes (n = 19). Participants' feedback on the process comprised three main themes: accessibility, richness in diversity, streamlining the development process.

CONCLUSIONS

It is important and feasible to develop guideline-based KPIs with a diverse stakeholder group. One hundred and ten KPIs were prioritised for inclusion in a suite of guideline-based KPIs for recurrent miscarriage care. Insights into our experiences may help others undertaking similar projects, particularly those undertaken in the absence of a clinical guideline and/or involving a range of stakeholders.

253 Innovative Teaching Early in Medical Career to Expose Medical Students to Surgery

Aim

At Lancashire Teaching Hospitals medical students begin their clinical career in Year 3 and are posted in General Surgery for 4 weeks, a relatively short period to experience the wide variety of surgical specialities and operative techniques. A surgical skills course - Lancashire Teaching Hospitals Surgical Skills for Medical Students (LTHSSMS) was designed and piloted. The aim was to assess the student experience of the LTHSSMS course conducted for Year 3 students at Lancashire Teaching Hospitals in 2019.

Method

This all-day course was optional, taught in groups of 15 students per course with a minimum of 2 experienced tutors. The LTHSSMS course included practical skills such as scrubbing, gloving, surgical knotting, suturing, excision of skin lesions and local anaesthetic techniques. It also included lectures on suture materials, abdominal incisions, laparoscopic and robotic surgery. There were interactive discussions to include non-technical skills, theatre in brief and WHO checklist.

Results

95% (n- 86) of students posted in surgery attended the course. 86.3% (n-75) felt the course was very relevant for their training. 90.7% (n-78) stated they enjoyed the course and 98.8% (n-85) stated they would recommend the course to fellow third-year students. 97.7% (n-84) stated the tutors delivered the course in an enthusiastic and positive manner. 79.1% (n-68) rated the audio video as excellent.

Conclusions

This course has provided a high impact surgical experience for the medical students at the beginning of their clinical careers. Similar opportunities if made available to students in all medical schools could improve and renew the interest in a surgical career.

A Systematic Review of Help-Seeking Interventions for Parents of Adolescents

PURPOSE

Parents do not always seek timely help for adolescents when the need arises. Although interventions to increase parental help-seeking have been evaluated and published, no systematic review of these interventions has been conducted. The aim of this systematic review is to collate, synthesise, and evaluate research on help-seeking interventions for parents of adolescents.

METHODS

Six electronic databases were searched from inception to May 2020 using terms related to the concepts of "parent" and "help-seeking" and focusing on parents of adolescents (aged 10-19 years). Methodological quality was assessed using the Quality Assessment Tool for Quantitative Studies; the Behavioural Change Taxonomy was used to code behavioral change techniques, and "promising interventions" were identified using pre-established criteria.

RESULTS

Eighteen studies met inclusion criteria, with six rated strong for design and methodology. The most frequently identified Behavioural Change Taxonomies included a credible source delivering the intervention, supporting parents, and providing prompts/cues regarding services/appointments. Four interventions were identified as "promising" because of strong methodology, significant positive outcomes, and strong evidence-base.

CONCLUSIONS

More high-quality, theory-driven parental help-seeking interventions using common outcome measures are needed to advance the literature in this area. Future research should replicate the promising interventions identified to develop best practice guidelines.

Comparing noninvasive sampling techniques with standard cannula sampling method for ruminal microbial analysis

•

Ruminal cannula is the gold standard for sampling rumen contents but is limited to few animals.

•

Noninvasive methods are needed as proxy for cannula to enable sampling larger numbers of cows.

•

Saliva, rumination bolus, tube-derived rumen samples, and feces were compared with cannula samples.

•

Microbial community in the solid fraction of tube samples mirrored that of cannula samples.

•

Rumination bolus may serve as a proxy for cannula samples under certain conditions.

Rumen microbes play an important role in the conversion of indigestible plant material to energy and protein in dairy cows. Sampling for ruminal contents via cannula is considered the gold standard technique for microbial analysis, but the technique requires ruminally cannulated animals and specialized animal facilities. The purpose of this study was to determine whether other sampling methods and locations along the digestive tract may serve as noninvasive proxies to the cannula method for microbial analysis. Six ruminally cannulated lactating Holstein dairy cows were adapted to a standard total mixed ration for 2 wk and sampled during the third week. Sampling locations and methods included salivary content, rumination bolus (regurgitated digesta collected from the cow's mouth), feces, and rumen contents via stomach tube and cannula. Stomach tube and cannula samples differ in proportions of solid and liquid material and were therefore separated into whole (as collected), liquid, and solid fractions. Samples were collected at 0 (before feeding), 2, 4, 6, 8, and 12 h after feeding over 2 d. All samples were extracted for total genomic DNA and selected samples for metabolically active DNA (RNA), PCR-amplified for the V1-V2 region of the 16S rRNA bacterial gene, and analyzed for bacterial diversity using the QIIME2 pipeline followed by statistical analysis in R (https://www.R-project.org/). In DNA-based analysis, at the community level, saliva, rumination bolus, and fecal samples clustered in separate groups, whereas all fractions of stomach tube and cannula samples clustered together, indicating that microbial communities of stomach tube and cannula samples were homogeneous. Rumination bolus samples at 6, 8, and 12 h after feeding clustered with stomach tube and cannula samples, indicating that rumination bolus samples may be an alternative for cannula samples; however, time of sampling is critical for sampling of bolus digesta. Results of the RNA-based analysis of rumination bolus samples and solid samples from cannula and stomach tube at 0 and 6 h after feeding were similar. We concluded that the solid fraction of samples obtained via the stomach tube method may serve as a proxy for the solid fraction of whole ruminal contents obtained via cannula for DNA-based microbial investigations. Both rumination bolus and stomach tube solid samples may serve as proxies for cannula solid samples for RNA-based microbial analysis.

Infertility and subsequent recurrent miscarriage: Current state of the literature and future considerations for practice and research

Background: Recurrent miscarriage (RM) and infertility are independently associated with adverse pregnancy outcomes, in addition to psychological sequelae. Experiencing pregnancy loss alongside infertility is particularly difficult. International guidance regarding RM is conflicting, and applicability to women with infertility is undetermined. The aim of this study was to: (i) establish if women/couples with a history of infertility are recognised in the literature on the investigation and management of RM, and (ii) determine if the specific needs of women/couples experiencing RM and infertility are ascertained and incorporated into clinical management strategies. Methods: We examined the wide-ranging literature to ascertain what gaps existed. Studies were retrieved through searches of PubMed and Google Scholar up to 21 January 2021 using appropriate controlled vocabulary and combinations of key words. No language or study design restrictions were applied. Results: While women/couples experiencing RM after infertility appear in studies evaluating investigations and proposed treatments, high-quality studies are lacking. Furthermore, they are largely excluded from international clinical guidance and qualitative research. Conclusions: The experiences of women/couples with RM and infertility and their specific care needs within maternity and fertility services are underexplored. It is unclear from current RM guidelines how best to manage and support this complex cohort. Women/couples with infertility and RM are underserved in the literature and in clinical guidance. Further robust studies are warranted to examine pregnancy outcomes, investigations and treatments currently used. Qualitative research is also required to identify their medical and psychological needs to better support this vulnerable group.

Clinical practice guidelines for recurrent miscarriage in high-income countries: a systematic review

Recurrent miscarriage affects 1-2% of women of reproductive age, depending on the definition used. A systematic review was conducted to identify, appraise and describe clinical practice guidelines (CPG) published since 2000 for the investigation, management, and/or follow-up of recurrent miscarriage within high-income countries. Six major databases, eight guideline repositories and the websites of 11 professional organizations were searched to identify potentially eligible studies. The quality of eligible CPG was assessed using the Appraisal of Guidelines for Research and Evaluation (AGREE II) Tool. A narrative synthesis was conducted to describe, compare and contrast the CPG and recommendations therein. Thirty-two CPG were included, from which 373 recommendations concerning first-trimester recurrent miscarriage were identified across four sub-categories: structure of care (42 recommendations, nine CPG), investigations (134 recommendations, 23 CPG), treatment (153 recommendations, 24 CPG), and counselling and supportive care (46 recommendations, nine CPG). Most CPG scored 'poor' on applicability (84%) and editorial independence (69%); and to a lesser extent stakeholder involvement (38%) and rigour of development (31%). Varying levels of consensus were found across CPG, with some conflicting recommendations. Greater efforts are required to improve the quality of evidence underpinning CPG, the rigour of their development and the inclusion of multi-disciplinary perspectives, including those with lived experience of recurrent miscarriage.

Effects of the macroalga Asparagopsis taxiformis and oregano leaves on methane emission, rumen fermentation, and lactational performance of dairy cows

Asparagopsis taxiformis (AT) is a source of multiple halogenated compounds and, in a limited number of studies, has been shown to decrease enteric CH₄ emission in vitro and in vivo. Similarly, oregano has been suggested as a potential CH₄ mitigating agent. This study consisted of 2 in vitro and 2 in vivo experiments. Experiment (Exp.) 1 was aimed at establishing the effect of AT on CH₄ emission in vitro. Two experiments (Exp. 2 and 3) with lactating dairy cows were conducted to determine the antimethanogenic effect of AT and oregano (Exp. 3) in vivo. Another experiment (Exp. 4) was designed to investigate stability of bromoform (CHBr₃) in AT over time. In Exp. 3, 20 Holstein cows were used in a replicated 4 × 4 Latin square design with four 28-d periods. Treatments were basal diet (control) or basal diet supplemented with (dry matter basis) 0.25% AT (LowAT), 0.50% AT (HighAT), or 1.77% oregano (Origanum vulgare L.) leaves. Enteric gas emissions were measured using the GreenFeed system (C-Lock Inc., Rapid City, SD), and rumen samples were collected for fermentation analysis using the ororuminal technique. In Exp.1 (in vitro), relative to the control, AT (at 1% dry matter basis, inclusion rate) decreased CH₄ yield by 98%. In Exp. 3, HighAT decreased average daily CH₄ emission and CH₄ yield by 65% and 55%, respectively, in experimental periods 1 and 2, but had no effect in periods 3 and 4. The differential response to AT among experimental periods was likely a result of a decrease in CHBr₃ concentration in AT over time, as observed in Exp. 4 (up to 84% decrease in 4 mo of storage). In Exp. 3, H₂ emission was increased by AT and, as expected, the proportion of acetate in the total volatile fatty acids in the rumen was decreased and those of propionate and butyrate were increased by HighAT compared with the control. Compared with the control, HighAT decreased dry matter intake, milk yield, and energy-corrected milk yield in Exp. 3. Milk composition was not affected by treatment, except lactose percentage and yield were decreased by HighAT. Concentrations of iodine and bromide in milk were increased by HighAT compared with the control. Milk CHBr₃ concentration and its organoleptic characteristics were not different between control and HighAT. Oregano had no effect on CH₄ emission or lactational performance of the cows in Exp. 3. Overall, AT included at 0.50% in the ration of dairy cows can have a large mitigation effect on enteric CH₄ emission, but dry matter intake and milk production may also decrease. There was a marked decrease in the CH₄ mitigation potential of AT in the second half of Exp. 3, likely resulting from CHBr₃ decay over time.

A protocol for a systematic review of clinical practice guidelines for recurrent miscarriage

Recurrent miscarriage (RM) was recently re-defined by the European Society of Human Reproduction and Embryology (ESHRE) as the loss of two or more consecutive pregnancies. Before this, and indeed still in some countries, RM was defined as three or more consecutive pregnancy losses. While the incidence of RM depends on the definition employed and population studied, it is generally accepted to affect 1-6% of women of reproductive age. Clinical practice guidelines (CPGs) for RM have been published by some professional organisations. While there are CPGs on miscarriage in Ireland, there are none concerning RM specifically. The aim of this systematic review is to identify, appraise and describe published CPGs for the management, investigation and/or follow-up of RM within high-income countries. Electronic databases (MEDLINE (Ovid ^®; 1946), Embase ^® (Elsevier; 1980), CINAHL Complete (EBSCOhost; 1994), Web of Science™ (Thomson Reuters), Scopus (Elsevier; 2004), and Open Grey (INIST-CNRS; 2011)), selected guideline repositories, and the websites of professional societies will be searched to identify CPGs, published within the last 20 years, for potential inclusion. Two reviewers will review abstracts and full texts independently against the eligibility criteria. Characteristics and recommendations of included CPGs will be extracted by one reviewer and double-checked by another. Two reviewers will use the Appraisal of Guidelines for Research and Evaluation version 2 (AGREE II) instrument independently to assess the quality of the included CPGs. Narrative synthesis will be conducted to appraise and compare CPGs and their recommendations or guidance therein. The identification, appraisal and description of published CPGs in other high-income countries will be a valuable first step in informing efforts to promote the optimisation and standardisation of RM care.

Optimal Timing of CT Scanning in the Rapid Access Lung Cancer Clinic

Aims To investigate whether a ‘CT first’ approach to Rapid Access Lung Cancer Clinic (RALC) review could be feasible in an Irish context. Methods A retrospective review of our institution’s Lung Cancer Database was performed. All RALC first attendances from 2012-2018 were identified. Timing of CT was assessed as well as CT imaging findings. Results Total first attendances in this period were 2372, of whom 91% had CT thorax as part of their evaluation. 866 patients (37%) were diagnosed with lung cancer, all had an abnormal CT. 1290 patients (54%) underwent CT but did not have lung cancer after clinical work up. 34% of patients diagnosed with Lung Cancer had their CT scan post RALC. Time to diagnosis was longer in those who had post RALC CT (34.5 versus 21 days) Conclusion CT scanning plays a vital role in the RALC pathway. Initial delays in obtaining CT can result in delayed time to diagnosis. These findings warrant close consideration when devising future national lung cancer policy.

Childhood obesity prevention: priority areas for future research and barriers and facilitators to knowledge translation, coproduced using the nominal group technique

Childhood obesity is a significant public health challenge, yet research priorities for childhood obesity prevention are not established. Coproduction of priorities leads to research which may be more translatable to the domains of policy and practice. The aim of the present study was to identify knowledge gaps and research priorities in addition to facilitators and barriers to knowledge translation in childhood obesity prevention. The nominal group technique involving consensus building with researchers, policymakers, and practitioners was employed during workshops at a national obesity conference held over 2 days in May 2017. Seventy-seven people participated in the first round of research prioritization on Day 1, while 14 stakeholders participated on Day 2. The top five research priorities identified were as follows: (i) Evaluate (including economic evaluation) current programs to inform practice and policy; (ii) How to change culture toward addressing the determinants of health; (iii) Implementation science: process; (iv) How to integrate obesity prevention into existing service structures; (v) How to enhance opportunities for habitual physical activity, including free play and active travel. Key themes emerging from this research prioritization exercise were the importance of funding and resources, coproduction of research, and a focus on both implementation research and social determinants within the field of childhood obesity prevention. The coproduced research priorities may help to shape the research agendas of funders and researchers, and aid in the conduct of policy-relevant research and the translation of research into practice in childhood obesity prevention.

A collaborative approach to developing sustainable behaviour change interventions for childhood obesity prevention: Development of the Choosing Healthy Eating for Infant Health (CHErIsH) intervention and implementation strategy

OBJECTIVES AND DESIGN

There is growing recognition of the need for effective behaviour change interventions to prevent chronic diseases that are feasible and sustainable and can be implemented within routine health care systems. Focusing on implementation from the outset of intervention development, and incorporating multiple stakeholder perspectives to achieve this, is therefore essential. This study explores the development of the Choosing Healthy Eating for Infant Health (CHErIsH) childhood obesity prevention intervention and implementation strategy to improve infant feeding behaviours.

METHODS

Five qualitative and quantitative evidence syntheses, two primary qualitative studies, and formal/informal consultations were conducted with practice, policy, research, and parent stakeholders. The Behaviour Change Wheel was used to guide the integration of findings.

RESULTS

The CHErIsH intervention targets parent-level behaviour change and comprises (1) brief verbal messages and (2) trustworthy resources, to be delivered by health care professionals (HCPs) during routine infant vaccination visits. The implementation strategy targets HCP-level behaviour change and comprises (1) a local opinion leader, (2) incentivized training, (3) HCP resources and educational materials, (4) electronic delivery prompts, (5) awareness-raising across all primary care HCPs, and (6) local technical support.

CONCLUSIONS

This study provides a rigorous example of the development of an evidence-based intervention aimed at improving parental infant feeding behaviours, alongside an evidence-based behaviour change strategy to facilitate implementation and sustainability in primary care. This approach demonstrates how to systematically incorporate multiple stakeholder perspectives with existing literature and move from multiple evidence sources to clearly specified intervention components for both the intervention and implementation strategy. Statement of Contribution What is already known? Incorporating insights from practice, policy, and public/patient stakeholders plays a key role in developing behaviour change interventions that are feasible and sustainable and can be implemented within routine health care systems. However, there are limited examples that provide in-depth guidance of how to do this using a systematic approach. What this study adds? This study describes an innovative use of the Behaviour Change Wheel to integrate multiple sources of evidence collected from practice, policy, research, and parent stakeholders to concurrently develop an evidence-based intervention to improve parental infant feeding behaviours and an implementation strategy to facilitate sustainable delivery by health care professionals in routine primary care.

Childhood fussy/picky eating behaviours: a systematic review and synthesis of qualitative studies

Fussy/picky eating behaviours are common across childhood. Recent reviews of the fussy eating literature focus on quantitative research and do not adequately account for families' subjective experiences, perceptions and practices. This review aims to synthesise the increasing volume of qualitative work on fussy eating. A systematic search of relevant databases was carried out. Studies were included if they were qualitative, published since 2008, with a primary focus on families' experiences, perceptions and practices regarding fussy eating, food neophobia, or food refusal in children (aged one to young adult). Studies with clinical samples, or relating to children under one year were excluded. Ten studies were eligible for this review and were synthesised using meta-ethnography (developed by Noblit and Hare). This review provides a comprehensive description and definition of fussy eating behaviours. A conceptual model of the family experience of fussy eating was developed, illustrating relationships between child characteristics (including fussy eating behaviours), parent feeding beliefs, parent feeding practices, mealtime emotions and parent awareness of food preference development. Our synthesis identified two ways in which fussy eating relates to mealtime emotions (directly and via parent feeding practices) and three distinct categories of parent beliefs that relate to fussy eating (self-efficacy, attributions and beliefs about hunger regulation). The model proposes pathways which could be explored further in future qualitative and quantitative studies, and suggests that parent beliefs, emotions, and awareness should be targeted alongside parent feeding practices to increase effectiveness of interventions. The majority of studies included in this review focus on pre-school children and all report the parent perspective. Further research is required to understand the child's perspective, and experiences of fussy eating in later childhood. PROSPERO Registration: CRD42017055943.

Effect of 2-hydroxy-4-(methylthio) butanoate (HMTBa) supplementation on rumen bacterial populations in dairy cows when exposed to diets with risk for milk fat depression

Diet-induced milk fat depression (MFD) is a condition marked by a reduction in milk fat yield experimentally achieved by increasing dietary unsaturated fatty acids and fermentable carbohydrates. 2-Hydroxy-4-(methylthio) butanoate (HMTBa) is a methionine analog observed to reduce diet-induced MFD in dairy cows. We hypothesize that the reduction in diet-induced MFD by HMTBa is due to changes in the rumen microbiota. To test this, 22 high-producing cannulated Holstein dairy cows were placed into 2 groups using a randomized block design and assigned to either control or HMTBa supplementation (0.1% of diet dry matter). All cows were then exposed to 3 different diets with a low risk (32% neutral detergent fiber, no added oil; fed d 1 to 7), a moderate risk (29% neutral detergent fiber and 0.75% soybean oil; fed d 8 to 24), or a high risk (29% neutral detergent fiber and 1.5% soybean oil; fed d 25 to 28) for diet-induced MFD. Rumen samples were collected on d 0, 14, 24, and 28, extracted for DNA, PCR-amplified for the V1-V2 region of the 16S rRNA gene, sequenced on an Illumina MiSeq (Illumina, San Diego, CA), and subjected to bacterial diversity analysis using the QIIME pipeline. The α diversity estimates (species richness and Shannon diversity) were decreased in the control group compared with the HMTBa group. Bacterial community composition also differed between control and HMTBa groups based on both weighted UniFrac (relative abundance of commonly detected bacteria) and unweighted UniFrac (presence/absence) distances. Within the HMTBa group, no differences were observed in bacterial community composition between d 0 and d 14, 24, and 28; however, in the control group, d 0 samples were different from d 14, 24, and 28. Certain bacterial genera including Dialister, Megasphaera, Lachnospira, and Sharpea were increased in the control group compared with the HMTBa group. Interestingly, these genera were positively correlated with milk fat trans-10,cis-12 conjugated linoleic acid and trans-10 C18:1, fatty acid isomers associated with biohydrogenation-induced MFD. It can be concluded that diet-induced MFD is accompanied by significant alterations in the rumen bacterial community and that HMTBa supplementation reduces these microbial perturbations.

The effectiveness of health professional-delivered interventions during the first 1000 days to prevent overweight/obesity in children: A systematic review

Childhood obesity is a global public health challenge. Early prevention, particularly during the first 1000 days, is advocated. Health professionals have a role to play in obesity prevention efforts, in part due to the multiple routine contacts they have with parents. We synthesized the evidence for the effectiveness of obesity prevention interventions delivered by health professionals during this time period, as reviews to date have not examined effectiveness by intervention provider. We also explored what behaviour change theories and/or techniques were associated with more effective intervention outcomes. Eleven electronic databases and three trial registers were searched from inception to 04 April 2019. A total of 180 studies, describing 39 trials involving 46 intervention arms, were included. While the number of interventions has grown considerably, we found some evidence for the effectiveness of health professional-delivered interventions during the first 1000 days. Only four interventions were effective on a primary (adiposity/weight) and secondary (behavioural) outcome measure. Twenty-two were effective on a behavioural outcome only. Several methodological limitations were noted, impacting on efforts to establish the active ingredients of interventions. Future work should focus on the conduct and reporting of interventions.
