RESUMO
Host-associated microbiomes can play important roles in the ecology and evolution of their insect hosts, but bacterial diversity in many insect groups remains poorly understood. Here we examine the relationship between host environment, host traits, and microbial diversity in three species in the ground beetle family (Coleoptera: Carabidae), a group of roughly 40,000 species that synthesize a wide diversity of defensive compounds. This study used 16S amplicon sequencing to profile three species that are phylogenetically distantly related, trophically distinct, and whose defensive chemical secretions differ: Anisodactylus similis LeConte, 1851, Pterostichus serripes (LeConte, 1875), and Brachinus elongatulus Chaudoir, 1876. Wild-caught beetles were compared to individuals maintained in the lab for two weeks on carnivorous, herbivorous, or starvation diets (n = 3 beetles for each species-diet combination). Metagenomic samples from two highly active tissue types-guts, and pygidial gland secretory cells (which produce defensive compounds)-were processed and sequenced separately from those of the remaining body. Bacterial composition and diversity of these ground beetles were largely resilient to controlled changes to host diet. Different tissues within the same beetle harbor unique microbial communities, and secretory cells in particular were remarkably similar across species. We also found that these three carabid species have patterns of microbial diversity similar to those previously found in carabid beetles. These results provide a baseline for future studies of the role of microbes in the diversification of carabids.

OBJECTIVES: The objective was to the undertake nominal group technique (NGT) to evaluate current exercise adherence measures and isolated domains to develop stakeholder consensus on the domains to include in the measurement of therapeutic exercise adherence for patients with musculoskeletal disorders. DESIGN: A 1-day NGT workshop was convened. Six exercise adherence measures were presented to the group that were identified in our recent systematic review. Discussions considered these measures and isolated domains of exercise adherence. Following discussions, consensus voting identified stakeholder agreement on the suitability of the six offered adherence measures and the inclusion of isolated domains of exercise adherence in future measurement. SETTING: One stakeholder NGT workshop held in Sheffield, UK. PARTICIPANTS: Key stakeholders from the UK were invited to participate from four identified populations. 14 participants represented patients, clinicians, researchers and service managers. RESULTS: All six exercise adherence measures were deemed not appropriate for use in clinical research or routine practice with no measure reaching 70% group agreement for suitability, relevance, acceptability or appropriateness. Three measures were deemed feasible to use in clinical practice. 25 constructs of exercise adherence did reach consensus threshold and were supported to be included as domains in the future measurement of exercise adherence. CONCLUSION: A mixed UK-based stakeholder group felt these six measures of exercise adherence were unacceptable. Differences in opinion within the stakeholder group highlighted the lack of consensus as to what should be measured, the type of assessment that is required and whose perspective should be sought when assessing exercise adherence. Previously unused domains may be needed alongside current ones, from both a clinician's and patient's perspective, to gain understanding and to inform future measurement development. Further conceptualisation of exercise adherence is required from similar mixed stakeholder groups in various socioeconomic and cultural populations.

Dysphagia is associated with increased risk of stroke-associated pneumonia (SAP). However, it is unclear what other factors contribute to that risk or which measures may reduce it. This systematic review aimed to provide evidence on interventions and care processes associated with SAP in patients with dysphagia. Studies were screened for inclusion if they included dysphagia only patients, dysphagia and non-dysphagia patients or unselected patients that included dysphagic patients and evaluated factors associated with a recorded frequency of SAP. Electronic databases were searched from inception to February 2017. Eligible studies were critically appraised. Heterogeneity was evaluated using I2. The primary outcome was SAP. Eleven studies were included. Sample sizes ranged from 60 to 1088 patients. There was heterogeneity in study design. Measures of immunodepression are associated with SAP in dysphagic patients. There is insufficient evidence to justify screening for aerobic Gram-negative bacteria. Prophylactic antibiotics did not prevent SAP and proton pump inhibitors may increase risk. Treatment with metoclopramide may reduce SAP risk. Evidence that nasogastric tube (NGT) placement increases risk of SAP is equivocal. A multidisciplinary team approach and instrumental assessment of swallowing may reduce risk of pneumonia. Patients with impaired mobility were associated with increased risk. Findings should be interpreted with caution given the number of studies, heterogeneity and descriptive analyses. Several medical interventions and care processes, which may reduce risk of SAP in patients with dysphagia, have been identified. Further research is needed to evaluate the role of these interventions and care processes in clinical practice.

AIM: To develop a theoretical framework to inform the design of interpersonal touch interventions intended to reduce stress in adult intensive care unit patients. DESIGN: Realist review with an intervention design-oriented approach. METHODS: We searched CINAHL, MEDLINE, EMBASE, CENTRAL, Web of Science and grey literature sources without date restrictions. Subject experts suggested additional articles. Evidence synthesis drew on diverse sources of literature and was conducted iteratively with theory testing. We consulted stakeholders to focus the review. We performed systematic searches to corroborate our developing theoretical framework. RESULTS: We present a theoretical framework based around six intervention construction principles. Theory testing provided some evidence in favour of treatment repetition, dynamic over static touch and lightening sedation. A lack of empirical evidence was identified for construction principles relating to intensity and positive/negative evaluation of emotional experience, moderate pressure touch for sedated patients and intervention delivery by relatives versus healthcare practitioners.
RESUMO
BACKGROUND: Patients with dysphagia are at an increased risk of stroke-associated pneumonia. There is wide variation in the way patients are screened and assessed during the acute phase. The aim of this review was to identify the methods of assessment and management in acute stroke that influence the risk of stroke-associated pneumonia. Studies of stroke patients that reported dysphagia screening, assessment or management and occurrence of pneumonia during acute phase stroke were screened for inclusion after electronic searches of multiple databases from inception to November 2016. The primary outcome was association with stroke-associated pneumonia. SUMMARY: Twelve studies of 87,824 patients were included. The type of dysphagia screening protocol varied widely across and within studies. There was limited information on what comprised a specialist swallow assessment and alternative feeding was the only management strategy, which was reported for association with stroke-associated pneumonia. Use of a formal screening protocol and early dysphagia screening (EDS) and assessment by a speech and language pathologist (SLP) were associated with a reduced risk of stroke-associated pneumonia. There was marked heterogeneity between the included studies, which precluded meta-analysis. Key Messages: There is variation in the assessment and management of dysphagia in acute stroke. There is increasing evidence that EDS and specialist swallow assessment by an SLP may reduce the odds of stroke-associated pneumonia. There is the potential for other factors to influence the incidence of stroke-associated pneumonia during the acute phase.

BACKGROUND: Aphasia assessment is traditionally divided into formal and informal approaches. Informal assessment is useful in developing a rich understanding of the person with aphasia's performance, e.g., describing performance in the context of real-world activities, and exploring the impact of environmental and/or partner supports upon communication. However, defining 'informal assessment' is problematic and can result in clinical issues including idiosyncratic practices regarding why, when and how to apply informal assessment. AIMS: To examine the extent to which the informal assessment literature can guide speech and language therapists (SLTs) in their clinical application of informal assessment for post-stroke aphasia. METHODS & PROCEDURES: A scoping review methodology was used. A systematic search of electronic databases (Scopus, Embase, PyscInfo, CINAHL, Ovid Medline and AMED) gave informal assessment references between 2000 and 2017 to which title/abstract and full-text screening against inclusion criteria were applied. Data were extracted from 28 resulting documents using an extraction template with fields based on the review's purpose. MAIN CONTRIBUTION: This review examines the informal assessment guidance regarding: rationale; areas of interest for informal assessment; available methods; procedural guidance; documentation; and analytical frameworks. The rationale for using informal assessment included several aspects such as gaining a 'representative' sample of the individual's language. Ten communication areas of interest were found with 13 different assessment methods. The procedural guidance for these methods varied considerably, with the exception of conversation and semi-structured interviewing. Overall, documentation guidance was limited but numerous analytical frameworks were found. CONCLUSIONS: Several informal assessment methods are available to SLTs. However, information is mixed regarding when they might be used or how they might be applied in terms of their administration, documentation and analysis.

Research that is integral into a 'learning healthcare system' can promote cost effective services and knowledge creation. As such, research is defined as a 'core function' in UK health service organisations, and is often planned through research and development (R&D) strategies that aim to promote research activity and research capacity development (RCD). The discussion focuses around the content of ten R&D strategies for healthcare organisations in England and Scotland, with respect to RCD. These organisations were engaged with a research interest network called ACORN (Addressing Organisational Capacity to do Research Network) that included two Scottish Health Boards, four community and mental health trusts, two provincial district hospitals, and two teaching hospitals. We undertook a thematic documentary analysis of the R&D strategies which identified 11 'core activities' of RCD. The potential for building research capacity in these 'core activities' was established by reviewing them through the lens of a RCD framework. Core activities aimed to 'hard wire' RCD into health organisations. They demonstrated a complex interplay between developing a strong internal organisational infrastructure, and supporting individual career planning and skills development, in turn enabled by organisational processes. They also included activities to build stronger inter-organisational relationships and networks. Practitioner, manager and patient involvement was a cross cutting theme. The potential to demonstrate progress was included in plans through monitoring activity across all RCD principles. Strategies were primarily aimed at research production rather than research use. Developing 'actionable dissemination' was poorly addressed in the strategies, and represents an area for improvement. We describe strengths of RCD planning activities, and opportunities for improvement. We explore how national policy and research funders can influence health systems' engagement in research.

OBJECTIVES: For women who have been diagnosed with unilateral breast cancer, there is an increasing trend for them to request removal of the contralateral healthy breast, the so-called contralateral risk reducing mastectomy (CRRM). The current literature is only just beginning to identify patient-reported reasons for undergoing CRRM and associated patient-reported outcomes. It is also unclear whether women at moderate/high risk of developing a subsequent primary contralateral breast cancer report similar outcomes to those considered to be at low/average risk. This lack of knowledge provides the rationale for this review. METHODS: A rapid review methodology was undertaken to identify and explore the published research literature focused on the longer term (>5 y) psychosocial impacts on women who undergo CRRM. RESULTS: Fifteen studies were identified. No UK studies were identified. High satisfaction and psychosocial well-being were consistently reported across all studies. Reducing the risk of a subsequent contralateral breast cancer and therefore reducing cancer-related anxiety, and satisfaction with cosmesis, were key themes running across all studies explaining satisfaction. Dissatisfaction was associated with adverse effects such as poor cosmesis, body image changes, femininity, sexual relationships, reoperations for acute and longer term complications, and reconstructive problems. CONCLUSIONS: Satisfaction and psychological well-being following CRRM was consistently high across all studies. However, the findings suggest women need to be more fully informed of the risks and benefits of CRRM and/or immediate/delayed reconstruction to support informed decision making.

BACKGROUND: The health benefits of physical activity (PA) have been extensively documented. Globally PA levels are low with only a small proportion of the population reaching recommended levels. Insufficient PA is seen as a major public health problem with high cost to society. Physiotherapists work with people to manage long-term conditions and are well placed to deliver individual interventions to increase PA. Despite this, little is known about the evidence that exists in this field. METHODS: This scoping review comprises a comprehensive search of key databases using predetermined search terms. This is supplemented with a parallel search that incorporated novel social media strands. In line with current guidance, a robust screening process took place using agreed inclusion and exclusion criteria. RESULTS: 31 studies met the inclusion criteria. The number of studies published annually increased over the decade. Ireland and USA yielded the largest number of publications with only 1 study from the UK. The target populations included physiotherapists and service users from a range of clinical populations. The studies were mainly quantitative and observational in design with a predominance of studies that scoped attitudes, perceptions, barriers and current practice. CONCLUSIONS: This reconnaissance has shown the state of the evidence to be sparse and disparate. However, the sharp rise in published work in recent years is encouraging. The predominance of scoping studies and the clear social, economic and political drivers for change in this area highlights a need for more pragmatic, interventional studies that can inform clinical practice.

Expansion of newborn screening programmes increases the complexity around reproductive choices, both in terms of the increased number of parents faced with making reproductive decisions from the earliest days of their affected child's life, and the number of conditions for which such decisions have to be made. We conducted a scoping review to explore: (i) reproductive decision-making among parents of children with recessive genetic conditions; and, (ii) the involvement of healthcare services in facilitating and supporting those decisions. Systematic search processes involved seven bibliographic databases, citation, and grey literature searches. From an initial total of 311 identified articles, seven met the inclusion criteria and were included in the review. The extracted data were organised around three themes: factors influencing reproductive decisions taken by parents, how those factors changed over time, and the involvement of healthcare services in supporting and facilitating reproductive decisions. Most studies focused on attitudes towards, and uptake of, pre-natal diagnosis (PND) and termination. None of the studies considered the wider range of reproductive choices facing all parents, including those of children with conditions for whom PND and termination is not available or where good health outcomes make these options less justifiable. The literature provided little insight into the role of healthcare staff in providing family planning support for these parents. There is a need to better understand the support parents need in their decision-making, and who is best placed to provide that support.

AIM: The aim of this study was to identify the factors contributing to lasting change in practice following a recovery-based training intervention for inpatient mental health rehabilitation staff. BACKGROUND: Staff training may help nurses and other staff groups in inpatient mental health rehabilitative settings to increase their recovery-oriented practice. There are no published reviews on the effectiveness of such training and few long-term evaluations. This review informed a realist evaluation of a specific intervention (GetREAL). DESIGN: Rapid realist review methodology was used to generate and prioritize programme theories. DATA SOURCES: ASSIA, CINAHL, Cochrane Library, Medline, PsycINFO, Scopus, Web of Science and grey literature searches were performed in September 2014-March 2015 with no date restrictions. Stakeholders suggested further documents. GetREAL project documentation was consulted. REVIEW METHODS: Programme theory development took place iteratively with literature identification. Stakeholders validated and prioritized emerging programme theories and the prioritized theories were refined using literature case studies. RESULTS: Fifty-one relevant documents fed into 49 programme theories articulating seven mechanisms for lasting change. Prioritized mechanisms were: staff receptiveness to change; and staff feeling encouraged, motivated and supported by colleagues and management to change. Seven programme theories were prioritized and refined using data from four case studies. CONCLUSION: Lasting change can be facilitated by collaborative action planning, regular collaborative meetings, appointing a change agent, explicit management endorsement and prioritization and modifying organizational structures. Conversely, a challenging organizational climate, or a prevalence of 'change fatigue', may block change. Pre-intervention exploration may help identify any potential barriers to embedding recovery in the organizational culture.

Objective: To recommend robust and relevant measures of exercise adherence for application in the musculoskeletal field. Method: A systematic review of measures was conducted in two phases. Phase 1 sought to identify all reproducible measures used to assess exercise adherence in a musculoskeletal setting. Phase 2 identified published evidence of measurement and practical properties of identified measures. Eight databases were searched (from inception to February 2016). Study quality was assessed against the Consensus-based Standards for the Selection of Health Measurement Instruments guidelines. Measurement quality was assessed against accepted standards. Results: Phase 1: from 8511 records, 326 full-text articles were reviewed; 45 reproducible measures were identified. Phase 2: from 2977 records, 110 full-text articles were assessed for eligibility; 10 articles provided evidence of measurement/practical properties for just seven measures. Six were exercise adherence-specific measures; one was specific to physical activity but applied as a measure of exercise adherence. Evidence of essential measurement and practical properties was mostly limited or not available. Assessment of relevance and comprehensiveness was largely absent and there was no evidence of patient involvement during the development or evaluation of any measure. Conclusion: The significant methodological and quality issues encountered prevent the clear recommendation of any measure; future applications should be undertaken cautiously until greater clarity of the conceptual underpinning of each measure is provided and acceptable evidence of essential measurement properties is established. Future research should seek to engage collaboratively with relevant stakeholders to ensure that exercise adherence assessment is high quality, relevant and acceptable.

BACKGROUND: Long-term change in recovery-based practice in mental health rehabilitation is a research priority. METHODS: We used a qualitative case study analysis using a blend of traditional 'framework' analysis and 'realist' approaches to carry out an evaluation of a recovery-focused staff training intervention within three purposively selected mental health rehabilitation units. We maximised the validity of the data by triangulating multiple data sources. RESULTS: We found that organisational culture and embedding of a change management programme in routine practice were reported as key influences in sustaining change in practice. The qualitative study generated 10 recommendations on how to achieve long-term change in practice including addressing pre-existing organisational issues and synergising concurrent change programmes. CONCLUSIONS: We propose that a recovery-focused staff training intervention requires clear leadership and integration with any existing change management programmes to facilitate sustained improvements in routine practice.

Missed appointments are an avoidable cost and resource inefficiency which impact upon the health of the patient and treatment outcomes. Health care services are increasingly utilizing reminder systems to manage these negative effects. This study explores the effectiveness of reminder systems for promoting attendance, cancellations, and rescheduling of appointments across all health care settings and for particular patient groups and the contextual factors which indicate that reminders are being employed sub-optimally. We used three inter-related reviews of quantitative and qualitative evidence. Firstly, using pre-existing models and theories, we developed a conceptual framework to inform our understanding of the contexts and mechanisms which influence reminder effectiveness. Secondly, we performed a review following Centre for Reviews and Dissemination guidelines to investigate the effectiveness of different methods of reminding patients to attend health service appointments. Finally, to supplement the effectiveness information, we completed a review informed by realist principles to identify factors likely to influence non-attendance behaviors and the effectiveness of reminders. We found consistent evidence that all types of reminder systems are effective at improving appointment attendance across a range of health care settings and patient populations. Reminder systems may also increase cancellation and rescheduling of unwanted appointments. "Reminder plus", which provides additional information beyond the reminder function may be more effective than simple reminders (ie, date, time, place) at reducing non-attendance at appointments in particular circumstances. We identified six areas of inefficiency which indicate that reminder systems are being used sub-optimally. Unless otherwise indicated, all patients should receive a reminder to facilitate attendance at their health care appointment. The choice of reminder system should be tailored to the individual service. To optimize appointment and reminder systems, health care services need supportive administrative processes to enhance attendance, cancellation, rescheduling, and re-allocation of appointments to other patients.
RESUMO
Healthcare workers make up 11% of British Columbia's workforce and, on an annual basis, they account for over 7,500 time-loss claims, 300,000 days of work lost, and a cost of more than $50 million in health claims as a result of musculo-skeletal injuries (MSIs) that occur in the workplace relating to patient care, over-exertion, slips, trips and violence. A new acute care hospital was constructed in Abbotsford, BC and opened in 2008. During this construction, extensive ceiling lift coverage was provided throughout the facility including in the operating room (OR). Given a lack of literature and research, around this important ergonomic engineering control in the OR environment, a staff survey was administered to capture information on the familiarity, usage, and perception of the ceiling lifts. Findings were positive and showed that the staff felt ceiling lifts were a practical and useful ergonomic engineering control, for the OR environment, and that key patient handling tasks were now being carried out with the use of ceiling lifts.

BACKGROUND: Exercise programmes are frequently advocated for the management of musculoskeletal disorders; however, adherence is an important pre-requisite for their success. The assessment of exercise adherence requires the use of relevant and appropriate measures, but guidance for appropriate assessment does not exist. This research will identify and evaluate the quality and acceptability of all measures used to assess exercise adherence within a musculoskeletal setting, seeking to reach consensus for the most relevant and appropriate measures for application in research and/or clinical practice settings. METHODS/DESIGN: There are two key stages to the proposed research. First, a systematic review of the quality and acceptability of measures used to assess exercise adherence in musculoskeletal disorders; second, a consensus meeting. The systematic review will be conducted in two phases and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to ensure a robust methodology. Phase one will identify all measures that have been used to assess exercise adherence in a musculoskeletal setting. Phase two will seek to identify published and unpublished evidence of the measurement and practical properties of identified measures. Study quality will be assessed against the COnsensus-based Standards for the selection of health Measurement Instruments (COSMIN) guidelines. A shortlist of best quality measures will be produced for consideration during stage two: a meeting of relevant stakeholders in the United Kingdom during which consensus on the most relevant and appropriate measures of exercise adherence for application in research and/or clinical practice settings will be sought. DISCUSSION: This study will benefit clinicians who seek to evaluate patients' levels of exercise adherence and those intending to undertake research, service evaluation, or audit relating to exercise adherence in the musculoskeletal field. The findings will impact upon new research studies which aim to understand the factors that predict adherence with exercise and which test different adherence-enhancing interventions.
