Past and future of human developmental biology.

Research directly on human embryos has gone through cycles of interest and neglect. The recent revitalization, including the making of 'human developmental biology', depended on fresh supplies of material and demand for medically relevant work. Human studies relied on mice but rejected simple extrapolation from this model mammal. Now, it is time to take stock while scanning the horizon for further change. Will research on human development be facilitated or frustrated? Will comparative approaches bring a greater variety of animal models into the picture? Will human stem-cell-based embryo models secure ever larger roles as exemplars of vertebrate development?

New consensus definition on defining and measuring care for children with paediatric feeding disorder.

AIM: This study addresses the absence of a definition of care for children with feeding disorders, limited agreement on key performance indicators (KPIs), and the lack of data linked to those KPIs. METHODS: Clinicians, consumers and researchers involved in outpatient feeding care in New South Wales (NSW), Australia were invited to participate in a two-Phase study. In Phase 1, a modified Delphi method was used. Two rounds of voting resulted in a new consensus definition of a multidisciplinary paediatric feeding clinic. Three further rounds voting determined relevant KPIs. In Phase 2, the KPIs were piloted prospectively in 10 clinics. RESULTS: Twenty-six clinicians, consumers and researchers participated in Phase 1. Participation across five voting rounds declined from 92% to 60% and a valid definition and KPI set were created. In Phase 2, the definition and KPIs were piloted in 10 clinics over 6 weeks. Data for 110 patients were collected. The final KPI set of 28 measures proposed covers clinical features, patient demographics and medical issues, parent-child interaction and outcome measures. CONCLUSIONS: A new definition of a multidisciplinary paediatric feeding clinic is now available, linked to a standardised KPI set covering relevant performance measures. These proved viable in baseline data collection for 10 clinics across NSW. This sets a foundation for further data collection, systematic measurement of care provision and outcomes, and research needed to deliver care improvement for children with paediatric feeding disorder.

Species Choice and Model Use: Reviving Research on Human Development.

While model organisms have had many historians, this article places studies of humans, and particularly our development, in the politics of species choice. Human embryos, investigated directly rather than via animal surrogates, have gone through cycles of attention and neglect. In the past 60 years they moved from the sidelines to center stage. Research was resuscitated in anatomy, launched in reproductive biomedicine, molecular genetics, and stem-cell science, and made attractive in developmental biology. I explain this surge of interest in terms of rivalry with models and reliance on them. The greater involvement of medicine in human reproduction, especially through in vitro fertilization, gave access to fresh sources of material that fed critiques of extrapolation from mice and met demands for clinical relevance or "translation." Yet much of the revival depended on models. Supply infrastructures and digital standards, including biobanks and virtual atlases, emulated community resources for model organisms. Novel culture, imaging, molecular, and postgenomic methods were perfected on less precious samples. Toing and froing from the mouse affirmed the necessity of the exemplary mammal and its insufficiency justified inquiries into humans. Another kind of model-organoids and embryo-like structures derived from stem cells-enabled experiments that encouraged the organization of a new field, human developmental biology. Research on humans has competed with and counted on models.

'it was that specialist that finally listened to us that's probably a weird answer to what you were expecting': Clinician and carer perspectives on brilliant feeding care.

INTRODUCTION: To extend research on positive aspects of health care, this article focusses on health care for children who tube-feed-this is because knowledge about tube-feeding for children is limited and fragmented. This is achieved by consulting with clinicians and carers who supported children who tube-feed to clarify their understandings of and experiences with brilliant feeding care. METHODS: Nine clinicians and nine carers who supported children who tube-fed were interviewed. The interview transcripts were analysed thematically. RESULTS: Findings highlighted several features of brilliant feeding care-namely: practices that go above and beyond; attentiveness; empowerment; being 'on the same page'; hopefulness and normalcy. CONCLUSIONS: These findings show that seemingly trivial or small acts of care can make a significant meaningful difference to carers of children who tube-feed. Such accounts elucidate brilliant care as grounded in feasible, everyday actions, within clinicians' reach. The implications associated with these findings are threefold. First, the findings highlight the need for clinicians to listen, be attuned and committed to the well-being of children who tube-feed and their carers, share decision-making, source resources, and instil hope. Second, the findings suggest that carers should seek out and acknowledge clinicians who listen, involve them in decision-making processes, and continue to source the resources required to optimize child and carer well-being. Third, the findings point to the need for research to clarify the models of care that foster brilliant feeding care, and the conditions required to introduce and sustain these models. PATIENT OR PUBLIC CONTRIBUTION: All of the carers and clinicians who contributed to this study were invited to participate in a workshop to discuss, critique, and sense-check the findings. Three carers and one clinician accepted this invitation. Collectively, they indicated that the findings resonated with them, and they agreed with the themes, which they indicated were well-substantiated by the data.

Inclusion and exclusion in the history of developmental biology.

Scientific disciplines embody commitments to particular questions and approaches, scopes and audiences; they exclude as well as include. Developmental biology is no exception, and it is useful to reflect on what it has kept in and left out since the field was founded after World War II. To that end, this article sketches a history of how developmental biology has been different from the comparative, human and even experimental embryologies that preceded it, as well as the embryology that was institutionalized in reproductive biology and medicine around the same time. Early developmental biology largely excluded evolution and the environment, but promised to embrace the entire living world and the whole life course. Developmental biologists have been overcoming those exclusions for some years, but might do more to deliver on the promises while cultivating closer relations, not least, to reproductive studies.

'Not birth, marriage or death, but gastrulation': the life of a quotation in biology.

This history of a statement attributed to the developmental biologist Lewis Wolpert exemplifies the making and uses of quotations in recent science. Wolpert's dictum, 'It is not birth, marriage or death, but gastrulation which is truly the most important time in your life', was produced in a series of international shifts of medium and scale. It originated in his vivid declaration in conversation with a non-specialist at a workshop dinner, gained its canonical form in a colleague's monograph, and was amplified as a quotation on a poster derived from an undergraduate project. Although it drew on Wolpert's authority and he accepted his authorship, it thus represents a collective sifting of earlier claims for the significance of prenatal existence through the values of 1980s developmental biology. Juxtaposing a technical term with major life events has let teachers engage students, and researchers entice journalists, while sharing an in-joke that came to mark community identity. Serious applications include arguing for an extension of the fourteen-day limit on human-embryo research. On this evidence, quotations have been kept busy addressing every audience of specialized knowledge.

Paediatric tube-feeding: An agenda for care improvement and research.

This article presents an agenda to improve the care and wellbeing of children with paediatric feeding disorder who require tube feeding (PFD-T). PFD-T requires urgent attention in practice and research. Priorities include: routine collection of PFD-T data in health-care records; addressing the tube-feeding lifecycle; and reducing the severity and duration of disruption caused by PFD-T where possible. This work should be underpinned by principles of involving, respecting and connecting families.

Cycles and circulation: a theme in the history of biology and medicine.

We invite systematic consideration of the metaphors of cycles and circulation as a long-term theme in the history of the life and environmental sciences and medicine. Ubiquitous in ancient religious and philosophical traditions, especially in representing the seasons and the motions of celestial bodies, circles once symbolized perfection. Over the centuries cyclic images in western medicine, natural philosophy, natural history and eventually biology gained independence from cosmology and theology and came to depend less on strictly circular forms. As potent 'canonical icons', cycles also interacted with representations of linear and irreversible change, including arrows, arcs, scales, series and trees, as in theories of the Earth and of evolution. In modern times life cycles and reproductive cycles have often been held to characterize life, in some cases especially female life, while human efforts selectively to foster and disrupt these cycles have harnessed their productivity in medicine and agriculture. But strong cyclic metaphors have continued to link physiology and climatology, medicine and economics, and biology and manufacturing, notably through the relations between land, food and population. From the grand nineteenth-century transformations of matter to systems ecology, the circulation of molecules through organic and inorganic compartments has posed the problem of maintaining identity in the face of flux and highlights the seductive ability of cyclic schemes to imply closure where no original state was in fact restored. More concerted attention to cycles and circulation will enrich analyses of the power of metaphors to naturalize understandings of life and their shaping by practical interests and political imaginations.

Reconstructing Robert Edwards: biography and the history of reproduction.

This commentary assesses Let There Be Life: An Intimate Portrait of Robert Edwards and His IVF Revolution by Roger Gosden (Jamestowne Bookworks, Williamsburg, VA, 2019, xxix + 359 pp., £15.99 / $19.99), an authorized biography of the IVF pioneer who founded this journal. It reflects on the challenges of placing Edwards in the history of studying reproduction, especially the rise of interest in infertility. It analyses Gosden's narrative choices and practices of reconstruction, in particular of experiences of seeing human eggs, embryos and fetuses. And it suggests that further research should explore the full spectrum of communication around Edwards with a view to illuminating the roles of scientists in transforming reproduction and to feeding back into a richer view of his life.

Parenting children who are enterally fed: How families go from surviving to thriving.

BACKGROUND: Complex feeding difficulties requiring enteral (tube) feeding affect everyone around the child. Parents experience additional stress and are at risk of social isolation. This study investigated the strategies families develop and use to adjust and adapt to enteral feeding so they were not just surviving but thriving as a family. METHODS: Twenty parents whose children had been or continued to be enterally fed were interviewed, four of them twice as their experience of enteral feeding progressed. Learning theory was used to conceptualize findings in terms of changing use of tools that mediated parents' response to feeding-related challenges. RESULTS: Parents encountered dilemmas relating to enteral feeding: maintaining participation in everyday activities, managing responses to the use of tubes for feeding, and doing what feels right for their child. They used four kinds of mediating tools to overcome these: memory aids and readiness tools, metaphors and narratives, repurposed everyday objects and personalized routines and materialities. CONCLUSIONS: This novel account of tool used to resolve dilemmas provides an empirically and theoretically grounded basis for supporting parents to thrive despite the challenges of enteral feeding. Specifically, it can guide information given to help parents anticipate and cope with dilemmas arising from enteral feeding.

A pedagogical framework for facilitating parents' learning in nurse-parent partnership.

Nursing work increasingly demands forms of expertise that complement specialist knowledge. In child and family nursing, this need arises when nurses work in partnership with parents of young children at risk. Partnership means working with parents in respectful, negotiated and empowering ways. Existing partnership literature emphasises communicative and relational skills, but this paper focuses on nurses' capacities to facilitate parents' learning. Referring to data from home visiting, day-stay and specialist toddler clinic services in Sydney, a pedagogical framework is presented. Analysis shows how nurses notice aspects of children, parents and parent-child interactions as a catalyst for building on parents' strengths, enhancing guided chance or challenging unhelpful constructs. Prior research shows the latter can be a sticking point in partnership, but this paper reveals diverse ways in which challenges are folded into learning process that position parents as agents of positive change. Noticing is dependent on embodied and communicative expertise, conceptualised in terms of sensory and reported channels. The framework offers a new view of partnership as mind-expanding for the parent and specifies the nurse's role in facilitating this process.

Nursing assistants matters-An ethnographic study of knowledge sharing in interprofessional practice.

Interprofessional collaboration involves some kind of knowledge sharing, which is essential and will be important in the future in regard to the opportunities and challenges in practices for delivering safe and effective health care. Nursing assistants are seldom mentioned as a group of health care workers that contribute to interprofessional collaboration in health care practice. The aim of this ethnographic study was to explore how the nursing assistants' knowledge can be shared in a team on a spinal cord injury rehabilitation ward. Using a sociomaterial perspective on practice, we captured different aspects of interprofessional collaboration in health care. The findings reveal how knowledge was shared between professionals, depending on different kinds of practice architecture. These specific cultural-discursive, material-economic, and social-political arrangements enabled possibilities through which nursing assistants' knowledge informed other practices, and others' knowledge informed the practice of nursing assistants. By studying what health care professionals actually do and say in practice, we found that the nursing assistants could make a valuable contribution of knowledge to the team.

Understanding partnership practice in primary health as pedagogic work: what can Vygotsky's theory of learning offer?

Primary health policy in Australia has followed international trends in promoting models of care based on partnership between professionals and health service users. This reform agenda has significant practice implications, and has been widely adopted in areas of primary health that involve supporting families with children. Existing research shows that achieving partnership in practice is associated with three specific challenges: uncertainty regarding the role of professional expertise, tension between immediate needs and longer-term capacity development in families, and the need for challenge while maintaining relationships based on trust. Recently, pedagogic or learning-focussed elements of partnership practice have been identified, but there have been no systematic attempts to link theories of learning with the practices and challenges of primary health-care professionals working with families in a pedagogic role. This paper explores key concepts of Vygotsky's theory of learning (including mediation, the zone of proximal development, internalisation, and double stimulation), showing how pedagogic concepts can provide a bridge between the policy rhetoric of partnership and primary health practice. The use of this theory to address the three key challenges is explicitly discussed.

Interprofessional learning at work: what spatial theory can tell us about workplace learning in an acute care ward.

It is widely recognized that every workplace potentially provides a rich source of learning. Studies focusing on health care contexts have shown that social interaction within and between professions is crucial in enabling professionals to learn through work, address problems and cope with challenges of clinical practice. While hospital environments are beginning to be understood in spatial terms, the links between space and interprofessional learning at work have not been explored. This paper draws on Lefebvre's tri-partite theoretical framework of perceived, conceived and lived space to enrich understandings of interprofessional learning on an acute care ward in an Australian teaching hospital. Qualitative analysis was undertaken using data from observations of Registered Nurses at work and semi-structured interviews linked to observed events. The paper focuses on a ward round, the medical workroom and the Registrar's room, comparing and contrasting the intended (conceived), practiced (perceived) and pedagogically experienced (lived) spatial dimensions. The paper concludes that spatial theory has much to offer understandings of interprofessional learning in work, and the features of work environments and daily practices that produce spaces that enable or constrain learning.

Understanding partnership practice in child and family nursing through the concept of practice architectures.

A significant international development agenda in the practice of nurses supporting families with young children focuses on establishing partnerships between professionals and service users. Qualitative data were generated through interviews and focus groups with 22 nurses from three child and family health service organisations, two in Australia and one in New Zealand. The aim was to explore what is needed in order to sustain partnership in practice, and to investigate how the concept of practice architectures can help understand attempts to enhance partnerships between nurses and families. Implementation of the Family Partnership Model (FPM) is taken as a specific point of reference. Analysis highlights a number of tensions between the goals of FPM and practice architectures relating to opportunities for ongoing learning; the role of individual nurses in shaping the practice; relationships with peers and managers; organisational features; and extra-organisational factors. The concept of practice architectures shows how changing practice requires more than developing individual knowledge and skills, and avoids treating individuals and context separately. The value of this framework for understanding change with reference to context rather than just individual's knowledge and skills is demonstrated, particularly with respect to approaches to practice development focused on providing additional training to nurses.

One site fits all? A student ward as a learning practice for interprofessional development.

Interprofessional training wards (IPTWs), aiming to enhance interprofessional collaboration, have been implemented in medical education and evaluated over the last decade. The Faculty of Health Sciences, Linköping University has, in collaboration with the local health provider, arranged such training wards since 1996, involving students from the medical, nursing, physiotherapy, and occupational therapy programs. Working together across professional boundaries is seen as a necessity in the future to achieve sustainable and safe healthcare. Therefore, educators need to arrange learning contexts which enhance students' interprofessional learning. This article shows aspects of how the arrangement of an IPTW can influence the students' collaboration and learning. Data from open-ended questions from a questionnaire survey, during autumn term 2010 and spring term 2011 at an IPTW, was analyzed qualitatively using a theoretical framework of practice theory. The theoretical lens gave a picture of how architectures of the IPTW create a clash between the "expected" professional responsibilities and the "unexpected" responsibilities of caring work. Also revealed was how the proximity between students opens up contexts for negotiations and boundary work. The value of using a theoretical framework of professional learning in practice within the frames of healthcare education is discussed.

Clinician and carer moral concerns when caring for children who tube-feed.

Child healthcare can be vexed by moral concerns - this extends to the care of children who tube-feed. Children who tube-feed often receive care from family members and clinicians of various disciplines. Each brings expertise, experiences, values, and views to a situation, prioritising the child's needs while attending to those they deem important in potentially disparate ways. Their understanding of a situation is shaped by beliefs, feelings, and perceptions. How then are key decisions made about the care of a child who tube-feeds? This article explores clinicians' and carers' moral concerns when caring for children who tube-feed. Interviews with clinicians (n = 9) and carers (n = 9) clarified three findings: first, there are often disparate beliefs about the need for tube-feeding; second, tube-feeding can evoke strong emotions; and third, it can be difficult to normalise tube-feeding. This article demonstrates how challenges can emerge when relationships between clinicians and carers diverge. Furthermore, it establishes how an ethic of care can bring different interests together to bolster the relationships required to optimise feeding care and promote health outcomes among children who tube-feed and their carers. This requires improved dialogue between and among clinicians and carers to create shared understandings of what is, what should be, and how to benefit children who tube-feed.

Working in partnership with parents: the experience and challenge of practice innovation in child and family health nursing.

AIMS AND OBJECTIVE: This study investigated what Family Partnership Model practice means in the day-to-day practice of child and family health nurses working with parents. BACKGROUND: The Family Partnership Model has been widely implemented in child and family health services in Australia and New Zealand, with limited understanding of the implications for nursing practice. DESIGN: A qualitative interpretive study design was used. METHOD: Semi-structured interviews were conducted with 22 nurse participants, who had completed the Family Partnership Model training programme. Subsequent focus groups enabled these participants to validate the themes identified in the initial analysis and to confirm that the nurses concurred with the issues raised. Thematic content analysis produced rich descriptions and explanation of nurses' experiences and perspectives. results: Four themes emerged from the analysis: experience of changing practices, exploring with parents, challenging unhelpful constructions and a commitment to examining practice. CONCLUSION: Overall, the participants embraced the use of the Family Partnership Model, providing examples of change and increasing confidence in their approach to working with parents. RELEVANCE TO CLINICAL PRACTICE: This study demonstrates that the effective utilisation of the Family Partnership Model in nursing practice is a more complex and dynamic process than simply embracing the model. There are significant challenges to be negotiated when implementing new ways of working with parents, particularly questioning existing dominant forms of practice for nurses, managers and wider health organisations, and their clients. This paper also raises issues about sustaining practice innovation, which extends beyond the best intent of individual nurses, requiring receptive organisational conditions and leadership.

Working in partnership with vulnerable families: the experience of child and family health practitioners.

Family circumstances in infancy are persistent and powerful determinants of children's physical and mental health, influencing inequalities that trace from childhood through to adulthood. While the social factors that perpetuate patterns of inequality are more complex than can be addressed through single interventions, child and family health (CFH) services represent crucial sites where trajectories of inequality can be disrupted. In particular, approaches that foster opportunities for practitioner-parent engagement that challenge traditional hierarchical health care practice, such as the Family Partnership Model (FPM), are recommended as ways of addressing disadvantage. Little is known about how practitioners implement models of working in partnership with families and, consequently, there is a gap in understanding how best to develop and sustain these new CFH practices. This paper reports a research project that investigated the experiences of 25 health professionals working within a FPM framework with vulnerable families. Through discussion of four key themes - redefining expertise, changing practices, establishing new relationships with parents and the complexities of partnership practice - the paper offers first-hand accounts of reframing practices that recognise the needs, skills and expertise of parents and thus contribute to empowerment of families.
