Older Adults’ Perspectives, Experiences, and Expectations of Ageing in England

  Background: Pessimism about ageing can have negative impacts on older people’s health and wellbeing and foster negative societal views of ageing and older people. These negative views can impact how people age, with more negative views producing more negative outcomes. To reduce ageism in society, concepts such as ageing well have been developed. However, our understanding of what ageing and ageing well means to older adults is limited. In this study, we will explore the perceptions, experiences, and expectations of ageing of older adults in England and develop a theory of ageing and ageing well. Methods/Design: A constructivist grounded theory approach will be used to interview 30-60 older adults from diverse backgrounds and locations in England. We will include healthy adults, adults with physical illnesses, people with dementia, and carers of people with dementia. Discussion: The findings will help to provide much needed information about whether people can age well, and what is needed to achieve this for people from diverse backgrounds. This could help to develop and highlight interventions and services needed to effectively meet the needs of the diverse ageing population. This could highlight action points for providing adequate targeted services and care and support for people as they age

Explaining anomalous responses to treatment in the Intensive Care Unit

The Intensive Care Unit (ICU) provides treatment to critically ill patients. When a patient does not respond as expected to such treatment it can be challenging for clinicians, especially junior clinicians, as they may not have the relevant experience to understand the patient’s anomalous response. Datasets for 10 patients from Glasgow Royal Infirmary’s ICU have been made available to us. We asked several ICU clinicians to review these datasets and to suggest sequences which include anomalous or unusual reactions to treatment. Further, we then asked two ICU clinicians if they agreed with their colleagues’ assessments, and if they did to provide possible explanations for these anomalous sequences. Subsequently we have developed a system which is able to replicate the clinicians’ explanations based on the knowledge contained in its several ontologies; further the system can suggest additional explanations which will be evaluated by the senior consultant

Size of supernumerary teats in sheep correlates with complexity of the anatomy and microenvironment.

Supernumerary nipples or teats (polythelia) are congenital accessory structures that may develop at any location along the milk line and have been implicated in the pathogenesis of mastitis. We describe the anatomy and histology of 27 spontaneously occurring supernumerary teats from 16 sheep, delineating two groups of teats - simple and anatomically complex - according to the complexity of the anatomy and microenvironment. Anatomically complex supernumerary teats exhibited significantly increased length and barrel diameter compared with simple supernumerary teats. A teat canal and/or teat cistern was present in anatomically complex teats, with smooth muscle fibres forming a variably well-organised encircling teat sphincter. Complex supernumerary teats also exhibited immune cell infiltrates similar to those of normal teats, including lymphoid follicle-like structures at the folds of the teat cistern-teat canal junction, and macrophages that infiltrated the peri-cisternal glandular tissue. One complex supernumerary teat exhibited teat end hyperkeratosis. These anatomical and histological features allow inference that supernumerary teats may be susceptible to bacterial ingress through the teat canal and we hypothesise that this may be more likely in those teats with less well-organised encircling smooth muscle. The teat cistern of anatomically complex teats may also constitute a focus of milk accumulation and thus a possible nidus for bacterial infection, potentially predisposing to mastitis. We suggest that size of the supernumerary teat, and relationship to the main teats, particularly in the case of 'cluster teats', should be considerations if surgical removal is contemplated.British Veterinary Association Animal Welfare Foundation (BVA AWF) Norman Hayward Fun

Adaptation of the DEMQOL-Proxy for routine use in care homes: a cross sectional study of the reliability and validity of DEMQOL-CH

Objective: To investigate the routine use of a measure of quality of life (QoL) in care homes and assess its psychometric properties when used by care staff Design: A cross-sectional two-phase study. Setting and participants: Data were collected from care staff in seven care homes in East Sussex, England. Method: Phase 1: The ability of care staff from two care homes to use the DEMQOL-Proxy without interviewer-administration was assessed using agreement analysis between a selfand interviewer-administered version of the instrument. Based on these findings, DEMQOLProxy was adapted into a new version, DEMQOL-CH, for use as a self-administered instrument in care homes. We assessed agreement between the new DEMQOL-CH and DEMQOL-Proxy to ensure DEMQOL-CH was used correctly. Phase 2: A preliminary assessment of the psychometric properties of DEMQOL-CH when used routinely was completed in a further five care homes. Results: Phase 1: Nineteen care staff from two care homes completed QoL measurements for residents. Systematic error was identified when staff self-completed the DEMQOL-Proxy without an interviewer. We modified the DEMQOL-Proxy to create DEMQOL-CH; this reduced the error, producing a version that could be used more accurately by care staff. Phase 2: Eleven care staff from five care homes rated resident QoL routinely. DEMQOL-CH showed acceptable psychometric properties with satisfactory reliability and validity and a clear factor structure. Conclusions: The research presents positive preliminary data on the acceptability, feasibility and performance of routine QoL measurement in care homes using an adapted version of DEMQOL-Proxy, the DEMQOL-CH. Results provide evidence to support the concept that routine measurement of QoL may be possible in care homes. Research is needed to refine and test the methodology and instrument further, and to explore the potential for benefits to residents, staff, and care homes in larger and more representative populations

Psychometric properties and feasibility of use of dementia specific quality of life instruments for use in care settings: a systematic review

Background: Over 400,000 people live in care home settings in the UK. One way of understanding and improving the quality of care provided is by measuring and understanding the quality of life (QoL) of those living in care homes. This review aimed to identify and examine the psychometric properties including feasibility of use of dementia-specific QoL measures developed or validated for use in care settings. Design: Systematic review. Methods: Instruments were identified using four electronic databases (PubMed, PsycINFO, Web of Science, and CINAHL) and lateral search techniques. Searches were conducted in January 2017. Studies which reported on the development and/or validation of dementia specific QoL instruments for use in care settings written in English were eligible for inclusion. The methodological quality of the studies was assessed using the COSMIN checklist. Feasibility was assessed using a checklist developed specifically for the review. Results: Six hundred and sixteen articles were identified in the initial search. After de-duplication, screening and further lateral searches were performed, 25 studies reporting on 9 dementia-specific QoL instruments for use in care home settings were included in the review. Limited evidence was available on the psychometric properties of many instruments identified. Higher-quality instruments were not easily accessible or had low feasibility of use. Conclusions: Few high-quality instruments of QoL validated for use in care home settings are readily or freely available. This review highlights the need to develop a well-validated measure of QoL for use within care homes that is also feasible and accessible

Parents’ journey through treatment for their child’s obesity: a qualitative study

Background: Treatment for childhood obesity is characterised by patient non-attendance and drop-out, and widespread failure to achieve weight maintenance. Qualitative methods may improve our understanding of patient perceptions and so improve treatment for childhood obesity. Aim: To provide insight into the perceptions of parents of obese children as they ‘journey’ from pre-treatment to end of treatment. Methods: We used purposive sampling and studied 17 parents of children attending 6-month outpatient treatments for obesity (BMI>98th percentile). Parent’s perceptions were explored by in-depth interviews, analysed using Framework methods. Results: Parents were characterised as being unaware of their child’s weight, in denial, or actively seeking treatment. Parents were consistently motivated to enter treatment due to perceived benefits to their child’s self esteem or quality of life, and weight outcomes appeared typically less important. During treatment parents expressed a lack of support for lifestyle changes outside the clinic, and noted that members of the extended family often undermined or failed to support lifestyle changes. Parents generally felt that treatment should have continued beyond six months, and it had provided benefits to their child’s well-being, self esteem, and quality of life, and this is what motivated many to remain engaged with treatment. Discussion: This study may help inform future treatments for childhood obesity by providing insights into the aspects of treatment of greatest importance to parents. Future treatments may need to consider providing greater support to lifestyle changes within the extended family, and may need to focus more on psycho-social outcomes

Implementation and evaluation of the VA DPP clinical demonstration: protocol for a multi-site non-randomized hybrid effectiveness-implementation type III trial.

BackgroundThe Diabetes Prevention Program (DPP) study showed that lifestyle intervention resulted in a 58% reduction in incidence of type 2 diabetes among individuals with prediabetes. Additional large randomized controlled trials have confirmed these results, and long-term follow-up has shown sustained benefit 10-20 years after the interventions ended. Diabetes is a common and costly disease, especially among Veterans, and despite strong evidence supporting the feasibility of type 2 diabetes prevention, the DPP has not been widely implemented. The first aim of this study will evaluate implementation of the Veterans Affairs (VA) DPP in three VA medical centers. The second aim will assess weight and hemoglobin A1c (A1c) outcomes, and the third aim will determine the cost-effectiveness and budget impact of implementation of the VA DPP from a health system perspective.Methods/designThis partnered multi-site non-randomized systematic assignment study will use a highly pragmatic hybrid effectiveness-implementation type III mixed methods study design. The implementation and administration of the VA DPP will be funded by clinical operations while the evaluation of the VA DPP will be funded by research grants. Seven hundred twenty eligible Veterans will be systematically assigned to the VA DPP clinical demonstration or the usual care VA MOVE!® weight management program. A multi-phase formative evaluation of the VA DPP implementation will be conducted. A theoretical program change model will be used to guide the implementation process and assess applicability and feasibility of the DPP for VA. The Consolidated Framework for Implementation Research (CFIR) will be used to guide qualitative data collection, analysis, and interpretation of barriers and facilitators to implementation. The RE-AIM framework will be used to assess Reach, Effectiveness, Adoption, Implementation, and Maintenance of the VA DPP. Twelve-month weight and A1c change will be evaluated for the VA DPP compared to the VA MOVE!ProgramMediation analyses will be conducted to identify whether program design differences impact outcomes.DiscussionFindings from this pragmatic evaluation will be highly applicable to practitioners who are tasked with implementing the DPP in clinical settings. In addition, findings will determine the effectiveness and cost-effectiveness of the VA DPP in the Veteran population

Transcriptional profiling reveals extraordinary diversity among skeletal muscle tissues

Skeletal muscle comprises a family of diverse tissues with highly specialized functions. Many acquired diseases, including HIV and COPD, affect specific muscles while sparing others. Even monogenic muscular dystrophies selectively affect certain muscle groups. These observations suggest that factors intrinsic to muscle tissues influence their resistance to disease. Nevertheless, most studies have not addressed transcriptional diversity among skeletal muscles. Here we use RNAseq to profile mRNA expression in skeletal, smooth, and cardiac muscle tissues from mice and rats. Our data set, MuscleDB, reveals extensive transcriptional diversity, with greater than 50% of transcripts differentially expressed among skeletal muscle tissues. We detect mRNA expression of hundreds of putative myokines that may underlie the endocrine functions of skeletal muscle. We identify candidate genes that may drive tissue specialization, including Smarca4, Vegfa, and Myostatin. By demonstrating the intrinsic diversity of skeletal muscles, these data provide a resource for studying the mechanisms of tissue specialization
