Electrocardiogram-gated Kilohertz Visualisation (EKV) Ultrasound Allows Assessment of Neonatal Cardiac Structural and Functional Maturation and Longitudinal Evaluation of Regeneration After Injury

The small size and high heart rate of the neonatal mouse heart makes structural and functional characterisation particularly challenging. Here, we describe application of electrocardiogram-gated kilohertz visualisation (EKV) ultrasound imaging with high spatio-temporal resolution to non-invasively characterise the post-natal mouse heart during normal growth and regeneration after injury. The 2-D images of the left ventricle (LV) acquired across the cardiac cycle from post-natal day 1 (P1) to P42 revealed significant changes in LV mass from P8 that coincided with a switch from hyperplastic to hypertrophic growth and correlated with ex vivo LV weight. Remodelling of the LV was indicated between P8 and P21 when LV mass and cardiomyocyte size increased with no accompanying change in LV wall thickness. Whereas Doppler imaging showed the expected switch from LV filling driven by atrial contraction to filling by LV relaxation during post-natal week 1, systolic function was retained at the same level from P1 to P42. EKV ultrasound imaging also revealed loss of systolic function after induction of myocardial infarction at P1 and regain of function associated with regeneration of the myocardium by P21. EKV ultrasound imaging thus offers a rapid and convenient method for routine non-invasive characterisation of the neonatal mouse heart

Please don’t put a price on our lives”: Social media and the contestation of value in Ireland’s pricing of orphan drugs.

This chapter combines two streams of scholarship—social media marketing and influence, and market organization—to examine two case studies of patient activism in the context of Irish drug pricing. The first is the provision of Orkambi, a drug for cystic fibrosis, which was approved in Ireland after eleven months of state/pharma negotiations held in a context of public debate and social media campaigning by people living with cystic fibrosis, their loved ones, and their advocates. The second case concerns the provision of Spinraza, a drug for patients with spinal muscular atrophy. In each case the chapter identifies key actors and tracks their social media activity with a view to identifying key turning points in the debate, relational links, and shifts. Ultimately the goal is to understand how activist organizations and individuals organize and reorganize the pharmaceutical market and the collective good through their actions and interactions on social media

Degron tagging for rapid protein degradation in mice

Degron tagging allows proteins of interest to be rapidly degraded, in areversible and tuneable manner, in response to a chemical stimulus.This provides numerous opportunities for understanding diseasemechanisms, modelling therapeutic interventions and constructingsynthetic gene networks. In recent years, many laboratories haveapplied degron tagging successfully in cultured mammalian cells,spurred by rapid advances in the fields of genome editing andtargeted protein degradation. In this At a Glance article, we focus onrecent efforts to apply degron tagging in mouse models, discussingthe distinct set of challenges and opportunities posed by the in vivoenvironmen

Perceptions of European medical staff on the facilitators and barriers to physical closeness between parents and infants in neonatal units

Aim Studies have provided insights into factors that may facilitate or inhibit parent–infant closeness in neonatal units, but none have specifically focused on the perspectives of senior neonatal staff. The aim of this study was to explore perceptions and experiences of consultant neonatologists and senior nurses in five European countries with regard to these issues. Methods Six small group discussions and three-one-to-one interviews were conducted with 16 consultant neonatologists and senior nurses representing nine neonatal units from Estonia, Finland, Norway, Spain and Sweden. The interviews explored facilitators and barriers to parent–infant closeness and implications for policy and practice, and thematic analysis was undertaken. Results Participants highlighted how a humanising care agenda that enabled parent–infant closeness was an aspiration, but pointed out that neonatal units were at different stages in achieving this. The facilitators and barriers to physical closeness included socio-economic factors, cultural norms, the designs of neonatal units, resource issues, leadership, staff attitudes and practices and relationships between staff and parents. Conclusion Various factors affected parent–infant closeness in neonatal units in European countries. There needs to be the political motivation, appropriate policy planning, legislation and resource allocation to increase measures that support closeness agendas in neonatal units

Impact of parenting resources on breastfeeding, parenting confidence and relationships

Objective: Pregnancy and the postnatal period offers an opportunity to optimise maternal health. A UK-based charity has developed parenting resources – Baby Buddy smartphone app, Baby Express magazine, and ‘From Bump to Breastfeeding’ DVD – designed to complement health service care to promote maternal wellbeing, breastfeeding and positive parenting. We evaluated the embedding of these resources into maternity and early years care pathways at three sites in the north of England. Here we present results relating to the impact of the resources on breastfeeding, women’s parenting confidence, and mother–infant bonding. Design and setting: We conducted a mixed-methods study comprising a qualitative interviews and women and care provider surveys at three sites. Women’s questionnaires were issued to two cohorts of postnatal women pre and post embedding of the resources. This questionnaire included validated scales (Iowa Infant Feeding Attitude Scale, Breastfeeding Self-Efficacy, Parenting Sense of Competency, Mother to Baby Bonding Scale), bespoke questions to elicit women’s views of the resources and infant feeding data. A survey of professionals in the post-embedding phase explored how the resources were used in practice. Interviews with stakeholders explored views of the resources and embedding process. We conducted descriptive and inferential statistics of quantitative data, and thematic analysis of qualitative data. Findings: There were 30 stakeholder interviews, 146 professionals completed a survey, and 161 and 192 women completed a survey before and after embedding, respectively. Receipt and use of the resources was relatively low, however, overall views of the resources were positive. There was no significant change in outcomes relating to infant feeding or parenting confidence, before and after embedding. After embedding, scores on the mother to baby bonding scale were significantly more positive when compared to pre-embedding scores. Key conclusions: While there were issues with the receipt and use of the resources, the resources were well received by women and professionals. While the resources did not appear to have influenced parents’ confidence and self-efficacy, there may be a positive impact on mother–infant bonding. Further research is needed to understand whether more focussed integration of the resources into care pathways over a longer term can increase user engagement, and the impact of such on key parenting outcomes

Qualitative exploration of women’s experiences of intramuscular pethidine or remifentanil patient-controlled analgesia for labour pain

ObjectivesTo explore women’s experiences of remifentanil or pethidine for labour pain and infant feeding behaviours at 6weeks post partum.DesignQualitative postnatal sub-study to the randomised controlled trial of remifentanil intravenous patient controlled analgesia (PCA) versus intramuscular pethidine for pain relief in labour (RESPITE). Semistructured telephone interviews were conducted at 6 weeks post partum, and thematic analysis was undertaken.SettingWomen recruited to the RESPITE trial from seven UK hospitals.ParticipantsEighty women consented and 49 (30 remifentanil group and 19 pethidine group) completed the interview.ResultsEight themes emerged which encompassed women’s antenatal plans for pain management (Birth Expectations) through to their future preferences for pain relief (Reflections for Future Choices). Many women who used remifentanil felt it provided effective pain relief (Effectiveness of Pain Relief), whereas women in the pethidine group expressed more mixed views. Both groups described side effects, with women using pethidine frequently reporting nausea (Negative Physiological Responses) and women using remifentanil describing more cognitive effects (Cognitive Effects). Some women who used remifentanil reported restricted movements due to technical aspects of drug administration and fear of analgesia running out (Issues with Drug Administration). Women described how remifentanil enabled them to maintain their ability to stay focused during the birth (Enabling a Sense of Control). There was little difference in reported breastfeeding initiation and continuation between pethidine and remifentanil groups (Impact on Infant Behaviour and Breastfeeding).ConclusionsQualitative insights from a follow-up study to a trial which explored experiences of intravenous remifentanil PCA with intramuscular pethidine injection found that remifentanil appeared to provide effective pain relief while allowing women to remain alert and focused during labour, although as with pethidine, some side effects were noted. Overall, there was little difference in reported breastfeeding initiation and duration between the two groups.Trial registration numberISRCTN29654603

Embedding supportive parenting resources into maternity and early years care pathways: a mixed methods evaluation

Background During pregnancy and postnatally, women seek information from a variety of sources. The potential to incorporate educational pregnancy and parenting resources into conventional health services is underexplored. In 2014–2016, UK-based charity Best Beginnings used an embedding model to embed three of their resources – the Baby Buddy app, Baby Express magazine, and ‘From Bump to Breastfeeding’ DVD – into maternity and early years care pathways at three sites in the north of England. A mixed-methods evaluation comprising an impact evaluation and a process evaluation was undertaken. Here we report findings from the process evaluation that aimed to understand the embedding process, explore maternity and early years’ professionals’ views and use of the resources, explore women’s engagement with and views of the resources, and identify barriers and facilitators to the embedding process. Methods We carried out semi-structured interviews with stakeholders (professionals involved in embedding) and observations of embedding activities to understand how embedding worked. Surveys of postnatal women were conducted over a two-month period both prior to, and after, the resources had been embedded, to ascertain engagement with and views of the resources. A survey of professionals was carried out post-embedding to understand how, where and when the resources were used in practice, and professionals’ views. Descriptive and thematic analyses were undertaken. Results Thirty stakeholders took part in interviews. Surveys were completed by 146 professionals, and by 161 and 192 women in the pre and post-embedding phases respectively. Themes derived from analysis of qualitative data were ‘Implementation of the embedding model’, ‘Promotion and distribution of, and engagement with, the resources’, ‘Fit with care pathways’, and ‘Perceptions of the resources’. While survey responses indicated that embedding of the resources into practice was not yet complete, those who had used the resources believed that they had helped increase knowledge, build confidence and support relationship-building. Conclusions Incorporating supportive parenting resources into maternity and early years’ care pathways requires a planned embedding approach, committed champions, and senior management support. Findings indicate largely positive views of women and professionals, and suggest the resources can be a beneficial aid for families

Assessment of Spectral Doppler in Preclinical Ultrasound Using a Small-Size Rotating Phantom

Preclinical ultrasound scanners are used to measure blood flow in small animals, but the potential errors in blood velocity measurements have not been quantified. This investigation rectifies this omission through the design and use of phantoms and evaluation of measurement errors for a preclinical ultrasound system (Vevo 770, Visualsonics, Toronto, ON, Canada). A ray model of geometric spectral broadening was used to predict velocity errors. A small-scale rotating phantom, made from tissue-mimicking material, was developed. True and Doppler-measured maximum velocities of the moving targets were compared over a range of angles from 10° to 80°. Results indicate that the maximum velocity was overestimated by up to 158% by spectral Doppler. There was good agreement (50%). The phantom is capable of validating the performance of blood velocity measurement in preclinical ultrasound
