RESUMO
INTRODUCTION: Lewy body dementia (LBD) is common, yet under-recognized and under-researched. To plan studies with the highest impact, engagement of the community personally affected by these conditions is essential. METHODS: A web-based survey of people living with LBD and current and former caregivers of people with LBD queried research priorities through forced ranking and exploration of burden of LBD symptoms. Specific caregiving needs in LBD and perceptions of research participation were also investigated. RESULTS: Between April 7, 2021 and July 1, 2021, 984 responses were recorded. Top research priorities included disease-modifying therapies and improved disease detection and staging. People with LBD were interested in pathophysiology and more bothered by motor symptoms; caregivers were interested in risk factors and symptomatic therapies and more bothered by neuropsychiatric symptoms. Few available LBD treatments and resources were rated as helpful, and many valuable services were never received. Previous participation in LBD research was infrequent, but interest was high. DISCUSSION: People with LBD and caregivers highlighted the need for research across all aspects of LBD, from pathophysiology and disease modification to prognosis, education, symptomatic treatments, and caregiver support. Funders should increase support for all aspects of LBD research to target the many needs identified by individuals and families living with LBD.

BACKGROUND: The prevalence of current or past coronavirus disease 2019 in skilled nursing facility (SNF) residents is unknown because of asymptomatic infection and constrained testing capacity early in the pandemic. We conducted a seroprevalence survey to determine a more comprehensive prevalence of past coronavirus disease 2019 in Los Angeles County SNF residents and staff members. METHODS: We recruited participants from 24 facilities; participants were requested to submit a nasopharyngeal swab sample for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) testing and a serum sample for detection of SARS-CoV-2 antibodies. All participants were cross-referenced with our surveillance database to identify persons with prior positive SARS-CoV-2 results. RESULTS: From 18 August to 24 September 2020, we enrolled 3305 participants (1340 residents and 1965 staff members). Among 856 residents providing serum samples, 362 (42%) had current or past SARS-CoV-2 infection. Of the 346 serology-positive residents, 199 (58%) did not have a documented prior positive SARS-CoV-2 PCR result. Among 1806 staff members providing serum, 454 (25%) had current or past SARS-CoV-2 infection. Of the 447 serology-positive staff members, 353 (79%) did not have a documented prior positive SARS-CoV-2 PCR result. CONCLUSIONS: Past testing practices and policies missed a substantial number of SARS-CoV-2 infections in SNF residents and staff members.

IMPORTANCE: Occupational therapy practitioners address the occupational performance and participation needs of people with Parkinson's disease (PD) and their care partners. OBJECTIVE: This Practice Guideline is informed by systematic reviews on the use of occupational therapy interventions to promote participation in occupations for people with PD and to facilitate their caregivers' participation in the caregiver role. This guideline is meant to support practitioners' clinical decision making when working with people with PD and their care partners. METHOD: We examined and synthesized the results of four systematic reviews and integrated those results into clinical recommendations for practice. RESULTS: Thirty-three articles from the systematic reviews served as the basis for the clinical recommendations in this Practice Guideline. Clinical recommendations are provided for interventions that have strong or moderate supporting evidence. CONCLUSION AND RECOMMENDATIONS: Multidisciplinary, tailored, goal-oriented intervention is recommended for people with PD. Various forms of exercise can be used to improve activities of daily living and instrumental activities of daily living performance and social participation, and interventions should incorporate health behavior change techniques to support adequate physical activity levels in daily life. Mindfulness meditation and exercise can be used to support sleep, and task-oriented training can be used to improve performance of specific tasks. Occupational therapy practitioners should incorporate self-management, coaching, compensatory, cognitive-behavioral, and other approaches into multicomponent treatment plans depending on the client's needs and goals. Additional potentially appropriate intervention approaches or areas to address are discussed on the basis of existing or emerging evidence and expert opinion. What This Article Adds: This Practice Guideline provides a summary and applications of the current evidence supporting occupational therapy intervention for people with PD. It includes case examples and suggested decision-making algorithms to support practitioners in addressing client goals.

Administration of medication via enteral feeding tubes (EFT) is common in cases where patients are unable to swallow the dosage form or a patient is intubated. The SARS-CoV-2 (COVID-19, coronavirus disease 2019) epidemic created a need to rapidly evaluate potential treatment options to address the global pandemic including evaluation of azithromycin (AZM) as a mono or combination therapy. Due to the complicating medical conditions of COVID-19, in some cases patients may be unable to take medication orally and could require medication administration by alternate routes such as an EFT. The aim of this study was an in vitro assessment for the dose preparation and simulated administration of AZM suspensions, prepared from tablets and capsules, via nasogastric feeding tubes (NGT). AZM tablets and capsules were used to prepare aqueous suspensions from 250 to 2000 mg for administration via NGT. NGT between 8 and 12 French (Fr), from common materials of construction and typical lengths were evaluated. About 20 mL syringes were used with water as the diluent. The preparation and simulated NGT administration steps for AZM suspensions were evaluated in the laboratory studies and included assessment of in-use stability of the aqueous suspensions, chemical compatibility of prepared aqueous suspensions with the syringe and NGT, ease of delivery and accuracy of simulated administration. Analysis of the prepared sample solutions for assay/impurities was performed using chromatographic conditions based on the USP-NF monograph. Verification of dose preparation and simulated administration was performed for intact tablets, crushed tablets, and capsules. Aqueous suspensions prepared from intact tablets and capsules were exposed to dosing materials (enteral syringe and NGT) for a period of up to 4 hours at ambient conditions. Assessment of the ease of dose delivery and analyses of the resulting samples for assay, purity and total degradation products were performed. The laboratory studies verified a procedure to reliably prepare suspensions from AZM tablets and capsules, over a range of 250 to 2000 mg, that can be accurately administered through NGT in sizes of 8 to 12 Fr. No incompatibilities of the prepared aqueous AZM suspension with dosing materials were observed and acceptable stability was demonstrated for up to 4 hours.
RESUMO
OBJECTIVE: Family meals promote healthful dietary intake and well-being among children. Despite these benefits, family meal participation typically declines as children age. This study utilises life course theory to explore parents' perceptions of family meals in order to understand how parents' past experiences with family meals (in childhood and earlier in adulthood) influence their current beliefs and practices regarding mealtimes with their own children. DESIGN: Semi-structured qualitative interviews. SETTING: In-person interviews were conducted in participants' homes. PARTICIPANTS: Twenty families (twenty-one mothers and fifteen fathers) with a child aged between 18 months and 5 years. RESULTS: Thematic analysis revealed that families seemed to primarily approach mealtimes from one of three overarching orientations: meals for (1) Togetherness, (2) Nutrition Messaging or (3) Necessity. These orientations were informed by parents' own mealtime experiences and significant life transitions (e.g. parenthood). The current family meal context, including the messages parents shared with their children during mealtimes and the challenges experienced with mealtimes, characterised the orientations and families' approaches to mealtimes. CONCLUSIONS: Parents' own early life experiences and significant life transitions influence why families eat meals together and have important implications for the intergenerational transmission of mealtime practices. Results may help to inform the content and timing of intervention strategies to support the continuation of frequent family meals beyond the preschool years.

AIM: To examine the numbers of asymptomatic infants <8 weeks who had appropriate thyroid function tests (TFTs) in addition to the newborn screening test, because of maternal thyroid disease, before and after the implementation of an updated institutional guideline and staff education. METHODS: A medical record audit of infants <8 weeks born at a metropolitan teaching hospital, who had TFTs between 1 July 2017 and 31 October 2017 was performed as part of a quality improvement project. Records were reviewed to determine the indication for testing and whether this complied with the current 2011 institutional guideline. A multidisciplinary staff education package was developed to coincide with the publication of an updated guideline in August 2018. Staff education and resources were provided throughout July 2018. A post-intervention audit was repeated between 1 August 2018 and 1 December 2018, assessing compliance with the 2018 guideline. RESULTS: In the baseline period, 40 of 457 infants born had TFTs performed, of which 26 of 40 (65%) were for maternal thyroid disease. Of these 10 of 26 (38%) met the 2011 criteria for testing; 1 of 26 (4%) met the updated 2018 criteria. In the post-intervention period, 14 of 412 infants born had TFTs of which 5 of 14 (36%) were tested due to maternal thyroid disease and all were compliant with the new guideline. CONCLUSIONS: Baseline audit revealed unnecessary neonatal thyroid function testing of healthy babies. Implementation of an updated guideline and a brief, targeted education package successfully increased awareness of the updated recommendations, reduced unnecessary testing and led to improved practice.

OBJECTIVES:: To explore the experiences of occupational therapists and physiotherapists and to reveal any factors that can facilitate delivering a complex care home intervention promoting meaningful activity. DESIGN:: Qualitative interview study using data from three focus groups conducted longitudinally post intervention implementation. Data were analysed thematically. SETTING:: Three residential care homes in South London, UK. SUBJECTS:: All therapists involved in the implementation of the intervention: three occupational therapists and three physiotherapists. RESULTS:: Three interconnected themes emerged from the analysis: (1) developing trusting relationships, (2) empowering staff and (3) remaining flexible. Therapists described how successfully implementing a complex care home intervention was dependant on developing trusting relationships with care staff. This enabled the therapists to empower care staff to take ownership of the intervention and help embed it in care home culture, facilitating long-term change. The therapists described how remaining flexible in their approach helped keep care staff engaged for the duration of implementation. CONCLUSION:: This study has revealed several important factors that can help facilitate therapists delivering complex interventions in care homes.

BACKGROUND: This article will review qualitative data from intervention-based counselling sessions to explore barriers to partner notification (PN) for South African men and women who have contracted sexually transmitted infections (STIs). This qualitative study took place in a township where there is high STI and HIV prevalence. In addition to reviewing barriers to PN, the study will also identify participants' perceptions about effective PN strategies that are presented during the intervention. Ultimately, the study will assess the intervention's impact on participants' motivation and skills to notify their partners about their STI status. METHODS: Relying on recorded counselling sessions from an intervention run by a parent study, this sub- study reviewed 30 transcripts from counselling sessions with 15 men and 15 women. The intervention was a 60 min interactive session where STI and HIV education, risk mitigation, and effective PN strategies were discussed. Participants were between 19 and 41 years old (mean age = 28.4) and lived within the catchment area of a South African township. Recordings were chosen based on verbal responsiveness of the participant and were manually coded for analysis. In addition, two programme counsellors were interviewed about their perceptions of the intervention and their experiences with participants to enhance rigour and reduce potential bias. RESULTS: By the conclusion of the intervention session, both male and female participants were motivated to notify their partners face-to-face about their positive STI status. Despite this, misperceptions about the etiology and transmission of STIs, as well as inadequate support from the clinical level and power imbalances amongst men and women emerged as major barriers for the prevention of future STIs. CONCLUSIONS: While the intervention appears to be successful in facilitating partners' intentions to notify, the data shows significant social and structural barriers that will create difficulties for the prevention of future STIs. Participants' persistent concerns about acquiring HIV or their current positive status affect decision-making and therefore, could be a window of opportunity for health-care providers or lay counsellors to discuss STIs in high prevalence areas.

BACKGROUND: Dementia is an international health priority and healthcare students need to be prepared to work with people living with dementia. There is a paucity of the literature describing appropriate educational interventions for pre-qualifying healthcare students and even fewer that are evaluated. METHODS: Based on available evidence, an education program was developed aiming to increase students' knowledge and confidence in working with people with dementia (PWD). An introductory program (IP) of classroom sessions and workshops was followed by a volunteer care home experience (CHE) (4 × 3 h). Piloted with physiotherapy (IP n = 55; CHE n = 6) and nursing students (IP n = 20; CHE n = 7), using a survey design, knowledge, and perceived confidence for working with PWD were measured at four time points; baseline, after the IP, after the CHE, and six months later. The data were analyzed using paired t-tests or non-parametric equivalents. RESULTS: Knowledge scores increased after the IP (Time 1-2, p < 0.001, n = 48) and increases were retained after six months (Time 1-4, p < 0.001, n = 40). Perceived confidence increased at six months follow up (Time 1-4, p < 0.001, n = 40) with peaks after the IP (Time 1-2, p < 0.001, n = 47) and CHE (Time 2-3, p = 0.004, n = 13). Physiotherapy and nursing students did not differ on knowledge, but nursing students were more confident at baseline and after the IP. Prior experience equated with greater confidence but no more knowledge. CONCLUSIONS: Findings indicate that students' knowledge and confidence to work with PWD improves after this educational intervention, with confidence improving more when supplemented by experience.

Plant polyphenols are known to have varying antimicrobial potencies, including direct antibacterial activity, synergism with antibiotics and suppression of bacterial virulence. We performed the in vitro oligomerization of resveratrol catalyzed by soybean peroxidase, and the two isomers (resveratrol-trans-dihydrodimer and pallidol) produced were tested for antimicrobial activity. The resveratrol-trans-dihydrodimer displayed antimicrobial activity against the Gram-positive bacteria Bacillus cereus, Listeria monocytogenes, and Staphylococcus aureus (minimum inhibitory concentration (MIC) = 15.0, 125, and 62.0 µM, respectively) and against Gram-negative Escherichia coli (MIC = 123 µM, upon addition of the efflux pump inhibitor Phe-Arg-ß-naphthylamide). In contrast, pallidol had no observable antimicrobial activity against all tested strains. Transcriptomic analysis implied downregulation of ABC transporters, genes involved in cell division and DNA binding proteins. Flow cytometric analysis of treated cells revealed a rapid collapse in membrane potential and a substantial decrease in total DNA content. The active dimer showed >90% inhibition of DNA gyrase activity, in vitro, by blocking the ATP binding site of the enzyme. We thus propose that the resveratrol-trans-dihydrodimer acts to: (1) disrupt membrane potential; and (2) inhibit DNA synthesis. In summary, we introduce the mechanisms of action and the initial evaluation of an active bactericide, and a platform for the development of polyphenolic antimicrobials.

Hypertension guidelines recommend team-based care for the treatment of high blood pressure (BP). Clinical pharmacists can help patients get to goal BP with rapid medication titration in conjunction with telehealth visits. We conducted a pharmacist-led home BP monitoring pilot program from June 2020 to September 2021. Forty-two patients with a SBP ≥140 despite using ≤2 antihypertensive medications were referred for pharmacist telehealth with expedited medication titration to achieve a BP goal <130/80. The mean enrollment SBP/DBP was 155.2 (SD, 15.8)/89.7 (SD, 11.5) mm Hg, and the mean completion SBP/DBP was 132.1 (SD, 10.9)/77.6 (SD, 10). The number of hypertension medications prescribed increased from 1.3 to 1.6 with no instances of falls or hypotension. At completion, 31% of patients had an automated office blood pressure (AOBP) with SBP <130 mm Hg and DBP <80 mm Hg. A pharmacist-led, home BP monitoring telehealth pilot program helped patients safely achieve BP goals.

BACKGROUND: Parkinson's disease (PD) is a complex neurodegenerative disorder impacting everyday function and quality of life. Rehabilitation plays a crucial role in improving symptoms, function, and quality of life and reducing disability, particularly given the lack of disease-modifying agents and limitations of medications and surgical therapies. However, rehabilitative care is under-recognized and under-utilized in PD and often only utilized in later disease stages, despite research and guidelines demonstrating its positive effects. Currently, there is a lack of consensus regarding fundamental topics related to rehabilitative services in PD. OBJECTIVE: The goal of the international Parkinson's Foundation Rehabilitation Medicine Task Force was to develop a consensus statement regarding the incorporation of rehabilitation in PD care. METHODS: The Task Force, comprised of international multidisciplinary experts in PD and rehabilitation and people directly affected by PD, met virtually to discuss topics such as rehabilitative services, existing therapy guidelines and rehabilitation literature in PD, and gaps and needs. A systematic, interactive, and iterative process was used to develop consensus-based statements on core components of PD rehabilitation and discipline-specific interventions. RESULTS: The expert-based consensus statement outlines key tenets of rehabilitative care including its multidisciplinary approach and discipline-specific guidance for occupational therapy, physical therapy, speech language pathology/therapy, and psychology/neuropsychology across all PD stages. CONCLUSIONS: Rehabilitative interventions should be an essential component in the comprehensive treatment of PD, from diagnosis to advanced disease. Greater education and awareness of the benefits of rehabilitative services for people with PD and their care partners, and further evidence-based and scientific study are encouraged.

Chloroplasts develop from undifferentiated plastids in response to light. In angiosperms, after the perception of light, the Elongated Hypocotyl 5 (HY5) transcription factor initiates photomorphogenesis, and two families of transcription factors known as GOLDEN2-LIKE (GLK) and GATA are considered master regulators of chloroplast development. In addition, the MIR171-targeted SCARECROW-LIKE GRAS transcription factors also impact chlorophyll biosynthesis. The extent to which these proteins carry out conserved roles in non-seed plants is not known. Using the model liverwort Marchantia polymorpha, we show that GLK controls chloroplast biogenesis, and HY5 shows a small conditional effect on chlorophyll content. Chromatin immunoprecipitation sequencing (ChIP-seq) revealed that MpGLK has a broader set of targets than has been reported in angiosperms. We also identified a functional GLK homolog in green algae. In summary, our data support the hypothesis that GLK carries out a conserved role relating to chloroplast biogenesis in land plants and green algae.

OBJECTIVES: Social scientists have demonstrated that family health work is interlinked with heteronormative gender inequities. Yet family-based public health interventions rarely incorporate a gender transformative approach or address heteronormativity as a potential health barrier in North America. Instead, attention to gender surfaces primarily in family health interventions conducted in low- to middle-income countries with majority Black and racialized populations. The objective of this article is to establish the importance of designing health interventions that account for heteronormative relations in Ontarian families by drawing on empirical data from the Guelph Family Health Study (GFHS). METHODS: We draw on data (February-October 2019) from (1) semi-structured interviews with 20 families and with 4 health educators facilitating the GFHS home visits and (2) observational data of 11 GFHS home visits and 1 health educator training day. Informed by gender transformation theory, data were analyzed and coded to understand the impact of gender, sexuality, and place in family health interventions. RESULTS: Pre-existing heteronormative parenting relations were reinforced through GFHS participation: the GFHS was mother-led, increasing some mothers' stress levels. Fathers tended to consider paid work a justification for disengaging from the GFHS, and their detachment sometimes obstructed mothers' intervention efforts. Health educators (all women) were caught in these relations, feeling like because of their gender, they were viewed by parents as confidants and marriage counsellors. CONCLUSION: Findings emphasize the need for expanding the epistemic and methodological approaches to family-based health interventions, changing the demographic and geographic emphasis within the field, and designing interventions that focus on societal-level changes. Heterosexuality has not been analyzed as a risk factor within the public health field, but our findings indicate the need for further study.
RéSUMé: OBJECTIFS: Les spécialistes des sciences sociales ont démontré que le travail en santé familiale est indissociable des inégalités hétéronormatives entre les sexes. Il est pourtant rare que les interventions sanitaires axées sur la famille intègrent une approche transformatrice du genre ou abordent l'hétéronormativité en tant qu'obstacle possible à la santé en Amérique du Nord. Au lieu de cela, l'attention au genre fait principalement surface dans les interventions en santé familiale menées dans des pays à faible revenu et à revenu intermédiaire dont les populations sont majoritairement noires et racisées. Notre article vise à souligner l'importance de concevoir des interventions sanitaires qui tiennent compte des relations hétéronormatives dans les familles ontariennes en puisant dans les données empiriques de l'étude Guelph Family Health Study (GFHS). MéTHODE: Nous avons fait appel aux données (févrieroctobre 2019) : 1) d'entretiens semi-directifs avec 20 familles et avec 4 éducatrices sanitaires ayant facilité des visites à domicile dans le cadre de la GFHS; et 2) d'observation de 11 visites à domicile menées dans le cadre de la GFHS et d'une journée de formation des éducatrices sanitaires. Éclairées par la théorie de la transformation de genre, les données ont été analysées et codées pour nous aider à comprendre les effets du sexe, de la sexualité et du lieu dans les interventions en santé familiale. RéSULTATS: Les relations parentales hétéronormatives préexistantes ont été renforcées par la participation à l'étude GFHS : ce sont surtout des mères qui y ont participé, ce qui a accru les niveaux de stress chez certaines. Les pères ont eu tendance à considérer leur travail rémunéré comme une raison de se retirer de l'étude, et leur détachement a parfois fait obstacle aux efforts d'intervention des mères. Les éducatrices sanitaires (toutes des femmes) ont été prises en étau dans ces relations et ont senti qu'en raison de leur sexe, elles étaient vues par les parents comme des confidentes et des conseillères conjugales. CONCLUSION: Nos constatations soulignent le besoin d'élargir les approches épistémiques et méthodologiques des interventions en santé familiale, de changer l'accent sur les données démographiques et géographiques dans le domaine et de concevoir des interventions axées sur les changements sociétaux. L'hétérosexualité n'est pas analysée en tant que facteur de risque dans le domaine de la santé publique, mais nos constatations indiquent le besoin de pousser la recherche en ce sens.

The high levels of biodiversity supported by mountains suggest a possible link between geologic processes and biological evolution. Freshwater biodiversity is high not only in tectonically active settings but also in tectonically quiescent montane regions such as the Appalachian Mountains. We show that erosion through different rock types drove allopatric divergence between lineages of the Greenfin Darter (Nothonotus chlorobranchius), a fish species endemic to rivers draining metamorphic rocks in the Tennessee River basin in the United States. In the past, metamorphic rock preferred by N. chlorobranchius was more widespread, but as erosion exposed other rock types, lineages of this species were progressively isolated in tributaries farther upstream, where metamorphic rock remained. Our results suggest a geologic mechanism for initiating allopatric diversification in mountains long after tectonic activity ceases.

The Tennessee Dace, Chrosomus tennesseensis (Starnes and Jenkins 1988), is a small minnow (Cypriniformes: Leuciscidae) found in the upper Tennessee River watershed and Graves Creek, in the Mobile River watershed. Chrosomus tennesseensis occurs sporadically throughout its range and has been listed as vulnerable by the IUCN (NatureServe). Until recently, C. tennesseensis had been known only to occur in the upper Tennessee River watershed, however, it has been discovered in headwaters of the Black Warrior River of the Mobile River watershed. We sequenced the mitochondrial genome of C. tennesseensis collected in the Mobile River watershed to better understand the colonization of the Mobile River watershed and the interspecific relationships of Chrosomus. Furthermore, the availability of the mitochondrial genome will assist in designing specific environmental DNA (eDNA) primers that will allow for less intrusive sampling of threatened and endangered Chrosomus species.
RESUMO
In this article we describe and analyze five videos created through an arts-informed research project, Precarious Inclusion: Studying Ontarian 2SLGBTQI+ parents' experiences childrearing in a post-legal parity framework. Precarious Inclusion used interviews and digital storytelling to investigate Ontario 2SLGBTQI+ parents' current experiences of inclusion and exclusion when navigating institutional and social interactions in everyday life in a post-legal parity context. The study centrally explored how intersecting identities with regards to sexuality, gender, geography, disability, class, race, Indigeneity, and ethnicity intersect with structural forces to influence 2SLGBTQI+ parents' inclusion and exclusion experiences. We examine research creation activities that supported 2SLGBTQI+ parents in making short videos about their experiences of parenting. Our analysis of the five videos created by Indigenous, racialized, trans, nonbinary, Two-Spirit, and disabled parents show how consistent experiences of exclusion mark 2SLGBTQI+ parents' everyday lives. We deepen theorizations of the material and psychological impacts of exclusion for 2SLGBTQI+ families through foregrounding three themes: 1) the operations of racism, white supremacy, and colonialism in makers' lives; 2) misrecognition and its psychic effects of bifurcation and disjuncture; and 3) love, joy, and multi-species kinship as powerful sites of healing and belonging. We further demonstrate how parents used their videos as self-advocacy for resisting precarious inclusion.
RESUMO
Psychedelic drugs are well-known for transiently altering perception, and in particular, for their visual effects. Although scientific interest into the substances' effects on perception increased during the first era of psychedelic research during the early to mid-20th century, there is currently no source where these findings have been synthesized. In addressing this gap, the current narrative review found that psychedelics were examined for their influences across all levels of the visual system (e.g., retinal, cortical, subcortical, simple visual processing, complex imagery, hallucinations). Psychedelics were also shown to affect auditory discrimination/generalization, neural correlates of auditory processing, and led to auditory hallucinations in subsets of participants. Several studies demonstrated that psychedelics can distort representations of body schema and time perception. Concerns regarding methodological standards of this era are a limitation to the findings and are discussed. Collectively, this review preserves and increases the accessibility of the work done by pioneering psychedelic/perception researchers, synthesizes findings, and critically analyzes areas of discrepancy to inform future studies.

OBJECTIVES: Maintaining physical activity for older residents in care homes maximises their physical and mental health and wellbeing, independence, dignity and quality of life. Unfortunately, most residents do not participate in regular physical activity. Active Residents in Care Homes, ARCH, was designed to increase physical activity by facilitating whole-system change in a care home. We evaluated whether ARCH can be delivered, its effects on resident's physical activity, wellbeing and costs. DESIGN: Feasibility study. SETTING: Three residential care homes. PARTICIPANTS: Care home residents and staff. INTERVENTION: Occupational and physiotherapists implemented ARCH over 4 months with an 8-month follow-up. MAIN OUTCOME MEASURES: Assessment of Physical Activity, Pool Activity Level, EQ5D-5L, Dementia Care Mapping, cost of implementing ARCH, health and social care utilisation. RESULTS: After implementing ARCH, residents displayed more positive behaviours, better mood and engagement and higher physical activity levels, but these improvements were not sustained at 8-month follow-up. The cost (2016 prices) of implementing ARCH was £61,037, which equates to £1,650/resident. Healthcare utilisation was £295/resident (SD320) in the 4 months prior to ARCH, £308/resident (SD406) during the 4-month implementation and £676/resident (SD438) in the 8-month follow-up. CONCLUSIONS: The ARCH programme can be delivered, it may have some short-term benefits and is affordable. Rather than have unrealistic increases in the health and longevity of older care home residents, ARCH may slow the decline in physical, mental and emotional well-being usually seen in older people in care homes, return some dignity and improve their quality of life in their last months or years.
