Do synaesthesia and mental imagery tap into similar cross-modal processes?

Synaesthesia has previously been linked with imagery abilities, although an understanding of a causal role for mental imagery in broader synaesthetic experiences remains elusive. This can be partly attributed to our relatively poor understanding of imagery in sensory domains beyond vision. Investigations into the neural and behavioural underpinnings of mental imagery have nevertheless identified an important role for imagery in perception, particularly in mediating cross-modal interactions. However, the phenomenology of synaesthesia gives rise to the assumption that associated cross-modal interactions may be encapsulated and specific to synaesthesia. As such, evidence for a link between imagery and perception may not generalize to synaesthesia. Here, we present results that challenge this idea: first, we found enhanced somatosensory imagery evoked by visual stimuli of body parts in mirror-touch synaesthetes, relative to other synaesthetes or controls. Moreover, this enhanced imagery generalized to tactile object properties not directly linked to their synaesthetic associations. Second, we report evidence that concurrent experience evoked in grapheme-colour synaesthesia was sufficient to trigger visual-to-tactile correspondences that are common to all. Together, these findings show that enhanced mental imagery is a consistent hallmark of synaesthesia, and suggest the intriguing possibility that imagery may facilitate the cross-modal interactions that underpin synaesthesic experiences.

Living beyond placenta accreta spectrum: parent's experience of the postnatal journey and recommendations for an integrated care pathway.

Placenta Accreta Spectrum is associated with significant clinical maternal morbidity and mortality, which has been extensively described in the literature. However, there is a dearth of research on the lived experiences of pregnant people and their support partners. The aim of this study is to describe living beyond a pregnancy and birth complicated by PAS for up to four years postpartum. Participants experiences inform the development of an integrated care pathway of family centered support interventions. An Interpretative Phenomenological Analysis approach was applied to collect data through virtual interviews over a 3-month period from February to April 2021. Twenty-nine participants shared their stories; six people with a history of PAS and their support partners were interviewed together (n = 12 participants), six were interviewed separately (n = 12 participants), and five were interviewed without their partner. Pregnant people were eligible for inclusion if they had a diagnosis of PAS within the previous 5 years. This paper focuses on the postnatal period, with data from the antenatal and intrapartum periods described separately. One superordinate theme "Living beyond PAS" emerged from interviews, with 6 subordinate themes as follows; "Living with a different body", "The impact on relationships", "Coping strategies", "Post-traumatic growth", "Challenges with normal care" and recommendations for "What needs to change". These themes informed the development of an integrated care pathway for pregnant people and their support partners to support them from diagnosis up to one year following the birth. Parents described the challenges of the postnatal period in terms of the physical and emotional impact, and how some were able to make positive life changes in the aftermath of a traumatic event. An integrated care pathway of simple supportive interventions, based on participant recommendations, delivered as part of specialist multidisciplinary team care may assist pregnant people and their support partners in alleviating some of these challenges

Proton lifetime bounds from chirally symmetric lattice QCD

We present results for the matrix elements relevant for proton decay in Grand Unified Theories (GUTs). The calculation is performed at a fixed lattice spacing a^{-1}=1.73(3) GeV using 2+1 flavors of domain wall fermions on lattices of size 16^3\times32 and 24^3\times64 with a fifth dimension of length 16. We use the indirect method which relies on an effective field theory description of proton decay, where we need to estimate the low energy constants, \alpha = -0.0112(25) GeV^3 and \beta = 0.0120(26) GeV^3. We relate these low energy constants to the proton decay matrix elements using leading order chiral perturbation theory. These can then be combined with experimental bounds on the proton lifetime to bound parameters of individual GUTs.Comment: 17 pages, 9 Figure

Nursing teamwork in the care of older people: A mixed methods study

Healthcare is increasingly complex and requires the ability to adapt to changing demands. Teamwork is essential to delivering high quality care and is central to nursing. The aims of this study were to identify the processes that underpin nursing teamwork and how these affect the care of older people, identify the relationship between perceived teamwork and perceived quality of care, and explore in depth the experience of working in nursing teams. The study was carried out in three older people's wards in a London teaching hospital. Nurses and healthcare assistants completed questionnaires (n=65) on known dynamics of teamwork (using the Nursing Teamwork Survey) together with ratings of organisational quality (using an adapted AHRQ HSPS scale). A sample (n=22; 34%) was then interviewed about their perceptions of care, teamwork and how good outcomes are delivered in everyday work. Results showed that many care difficulties were routinely encountered, and confirmed the importance of teamwork (e.g. shared mental models of tasks and team roles and responsibilities, supported by leadership) in adapting to challenges. Perceived quality of teamwork was positively related to perceived quality of care. Work system variability and the external environment influenced teamwork, and confirmed the importance of team adaptive capacity. The CARE model shows the centrality of teamwork in adapting to variable demand and capacity to deliver care processes, and the influence of broader system factors on teamworking
