An fMRI sSudy of Imagined Self-Rotation
In the present study, functional magnetic resonance imaging was used to examine the neural mechanisms involved in the imagined spatial transformation of one\u27s body. The task required subjects to update the position of one of four external objects from memory after they had performed an imagined self-rotation to a new position. Activation in the rotation condition was compared with that in a control condition in which subjects located the positions of objects without imagining a change in self-position. The results indicated similar networks of activation to other egocentric transformation tasks involving decisions about body parts. The most significant area of activation was in the left posterior parietal cortex. Other regions of activation common among several of the subjects were secondary visual, premotor, and frontal lobe regions. These results are discussed relative to motor and visual imagery processes as well as to the distinctions between the present task and other imagined egocentric transformation tasks
Place matters: but does local leadership?
The arrival of New Labour into Government witnessed the prominent re-emergence of place onto the policy agenda. This heralded a range of area-based-initiatives designed to both tackle neighbourhood forms of deprivation and to re-establish a sense of identity and connection between individuals and their local community. In terms of place-making, effective and inclusive participation, representation and leadership were all identified as prerequisites for the creation of sustainable communities . But how important is local leadership and strategic vision within local public service organisations in achieving the desired place-making outcomes? This paper examines the extent to which local leadership and strategic vision represents a significant factor in promoting higher levels of satisfaction, belonging, cohesion and participation across single tier councils in England. The ensuing empirical evidence raises significant questions not only about the importance of local leadership in place-making, but also the environmental and organizational factors that shape local places
Pilot cluster randomised trial of an evidence-based intervention to reduce avoidable hospital admissions in nursing home residents (Better Health in Residents of Care Homes with Nursing—BHiRCH-NH Study)
Objectives: To pilot a complex intervention to support healthcare and improve early detection and treatment for common health conditions experienced by nursing home (NH) residents. /
Design: Pilot cluster randomised controlled trial. /
Setting: 14 NHs (7 intervention, 7 control) in London and West Yorkshire. /
Participants: NH residents, their family carers and staff. /
Intervention: Complex intervention to support healthcare and improve early detection and treatment of urinary tract and respiratory infections, chronic heart failure and dehydration, comprising: (1) ‘Stop and Watch (S&W)’ early warning tool for changes in physical health, (2) condition-specific care pathway and (3) Situation, Background, Assessment and Recommendation tool to enhance communication with primary care. Implementation was supported by Practice Development Champions, a Practice Development Support Group and regular telephone coaching with external facilitators. /
Outcome measures: Data on NH (quality ratings, size, ownership), residents, family carers and staff demographics during the month prior to intervention and subsequently, numbers of admissions, accident and emergency visits, and unscheduled general practitioner visits monthly for 6 months during intervention. We collected data on how the intervention was used, healthcare resource use and quality of life data for economic evaluation. We assessed recruitment and retention, and whether a full trial was warranted. /
Results: We recruited 14 NHs, 148 staff, 95 family carers and 245 residents. We retained the majority of participants recruited (95%). 15% of residents had an unplanned hospital admission for one of the four study conditions. We were able to collect sufficient questionnaire data (all over 96% complete). No NH implemented intervention tools as planned. Only 16 S&W forms and 8 care pathways were completed. There was no evidence of harm. /
Conclusions: Recruitment, retention and data collection processes were effective but the intervention not implemented. A full trial is not warranted.

Smc5/6 coordinates formation and resolution of joint molecules with chromosome morphology to ensure meiotic divisions
During meiosis, Structural Maintenance of Chromosome (SMC) complexes underpin two fundamental features of meiosis: homologous recombination and chromosome segregation. While meiotic functions of the cohesin and condensin complexes have been delineated, the role of the third SMC complex, Smc5/6, remains enigmatic. Here we identify specific, essential meiotic functions for the Smc5/6 complex in homologous recombination and the regulation of cohesin. We show that Smc5/6 is enriched at centromeres and cohesin-association sites where it regulates sister-chromatid cohesion and the timely removal of cohesin from chromosomal arms, respectively. Smc5/6 also localizes to recombination hotspots, where it promotes normal formation and resolution of a subset of joint-molecule intermediates. In this regard, Smc5/6 functions independently of the major crossover pathway defined by the MutLγ complex. Furthermore, we show that Smc5/6 is required for stable chromosomal localization of the XPF-family endonuclease, Mus81-Mms4Eme1. Our data suggest that the Smc5/6 complex is required for specific recombination and chromosomal processes throughout meiosis and that in its absence, attempts at cell division with unresolved joint molecules and residual cohesin lead to severe recombination-induced meiotic catastroph
Evidence-based intervention to reduce avoidable hospital admissions in care home residents (the Better Health in Residents in Care Homes (BHiRCH) study): Protocol for a pilot cluster randomised trial
YesIntroduction: Acute hospital admission is distressing for care home residents. Ambulatory care sensitive conditions, such as respiratory and urinary tract infections, are conditions that can cause unplanned hospital admission but may have been avoidable with timely detection and intervention in the community. The Better Health in Residents in Care Homes (BHiRCH) programme has feasibility tested and will pilot a multicomponent intervention to reduce these avoidable hospital admissions. The BHiRCH intervention comprises an early warning tool for noting changes in resident health, a care pathway (clinical guidance and decision support system) and a structured method for communicating with primary care, adapted for use in the care home. We use practice development champions to support implementation and embed changes in care.
Methods and analysis: Cluster randomised pilot trial to test study procedures and indicate whether a further definitive trial is warranted. Fourteen care homes with nursing (nursing homes) will be randomly allocated to intervention (delivered at nursing home level) or control groups. Two nurses from each home become Practice Development Champions trained to implement the intervention, supported by a practice development support group. Data will be collected for 3 months preintervention, monthly during the 12-month intervention and 1 month after. Individual-level data includes resident, care partner and staff demographics, resident functional status, service use and quality of life (for health economic analysis) and the extent to which staff perceive the organisation supports person centred care. System-level data includes primary and secondary health services contacts (ie, general practitioner and hospital admissions). Process evaluation assesses intervention acceptability, feasibility, fidelity, ease of implementation in practice and study procedures (ie, consent and recruitment rates).UK NIHR grant number RP-PG-0612-20010

A complex intervention to reduce avoidable hospital admissions in nursing homes: a research programme including the BHiRCH-NH pilot cluster RCT
YesBackground: An unplanned hospital admission of a nursing home resident distresses the person, their
family and nursing home staff, and is costly to the NHS. Improving health care in care homes, including
early detection of residents’ health changes, may reduce hospital admissions. Previously, we identified four
conditions associated with avoidable hospital admissions. We noted promising ‘within-home’ complex
interventions including care pathways, knowledge and skills enhancement, and implementation support.
Objectives: Develop a complex intervention with implementation support [the Better Health in
Residents in Care Homes with Nursing (BHiRCH-NH)] to improve early detection, assessment and
treatment for the four conditions. Determine its impact on hospital admissions, test study procedures
and acceptability of the intervention and implementation support, and indicate if a definitive trial
was warranted.
Design: A Carer Reference Panel advised on the intervention, implementation support and study
documentation, and engaged in data analysis and interpretation. In workstream 1, we developed a
complex intervention to reduce rates of hospitalisation from nursing homes using mixed methods,
including a rapid research review, semistructured interviews and consensus workshops. The complex
intervention comprised care pathways, approaches to enhance staff knowledge and skills, implementation
support and clarity regarding the role of family carers. In workstream 2, we tested the complex intervention
and implementation support via two work packages. In work package 1, we conducted a feasibility study
of the intervention, implementation support and study procedures in two nursing homes and refined
the complex intervention to comprise the Stop and Watch Early Warning Tool (S&W), condition-specific
care pathways and a structured framework for nurses to communicate with primary care. The final
implementation support included identifying two Practice Development Champions (PDCs) in each
intervention home, and supporting them with a training workshop, practice development support group,
monthly coaching calls, handbooks and web-based resources. In work package 2, we undertook a cluster
randomised controlled trial to pilot test the complex intervention for acceptability and a preliminary
estimate of effect.
Setting: Fourteen nursing homes allocated to intervention and implementation support (n = 7) or
treatment as usual (n = 7).
Participants: We recruited sufficient numbers of nursing homes (n = 14), staff (n = 148), family carers
(n = 95) and residents (n = 245). Two nursing homes withdrew prior to the intervention starting.
Intervention: This ran from February to July 2018.
Data sources: Individual-level data on nursing home residents, their family carers and staff; system-level
data using nursing home records; and process-level data comprising how the intervention was implemented.
Data were collected on recruitment rates, consent and the numbers of family carers who wished to be
involved in the residents’ care. Completeness of outcome measures and data collection and the return
rate of questionnaires were assessed.
Results: The pilot trial showed no effects on hospitalisations or secondary outcomes. No home
implemented the intervention tools as expected. Most staff endorsed the importance of early detection,
assessment and treatment. Many reported that they ‘were already doing it’, using an early-warning tool;
a detailed nursing assessment; or the situation, background, assessment, recommendation communication
protocol. Three homes never used the S&W and four never used care pathways. Only 16 S&W forms and
eight care pathways were completed. Care records revealed little use of the intervention principles. PDCs
from five of six intervention homes attended the training workshop, following which they had variable
engagement with implementation support. Progression criteria regarding recruitment and data collection
were met: 70% of homes were retained, the proportion of missing data was < 20% and 80% of individuallevel data were collected. Necessary rates of data collection, documentation completion and return over
the 6-month study period were achieved. However, intervention tools were not fully adopted, suggesting
they would not be sustainable outside the trial. Few hospitalisations for the four conditions suggest it an
unsuitable primary outcome measure. Key cost components were estimated.
Limitations: The study homes may already have had effective approaches to early detection, assessment and
treatment for acute health changes; consistent with government policy emphasising the need for enhanced
health care in homes. Alternatively, the implementation support may not have been sufficiently potent.
Conclusion: A definitive trial is feasible, but the intervention is unlikely to be effective. Participant
recruitment, retention, data collection and engagement with family carers can guide subsequent
studies, including service evaluation and quality improvement methodologies.
Future work: Intervention research should be conducted in homes which need to enhance early
detection, assessment and treatment. Interventions to reduce avoidable hospital admissions may be
beneficial in residential care homes, as they are not required to employ nurses.This project was funded by the National Institute for Health Research (NIHR) Programme Grants for Applied Research programme and will be published in full in Programme Grants for Applied Research; Vol. 9, No. 2.
