ASSIST: a reablement program for older adults in Sweden - a feasibility study.

BACKGROUND: Western countries emphasise the provision of assistive home care by implementing reablement services. Reablement services are offered to a limited degree in Sweden, and systematic research regarding outcomes and how reablement can be tailored to maximize benefits for older adults has been lacking. This study aimed to evaluate the feasibility of a novel reablement program (ASSIST 1.0) regarding study design and outcome measures, as well as fidelity, adherence, and acceptability of the program in a Swedish context. METHOD: A non-randomised, quasi-experimental, mixed-method, pre/post-test design was applied with an intervention group receiving ASSIST 1.0 (n = 7) and a control group receiving regular home care (n = 10). ASSIST 1.0 was developed to empower older adults to increase their perceived performance and satisfaction of performing activities in everyday life as well as increase their perceived health, self-efficacy, and well-being. ASSIST 1.0 was founded on the concept of reablement and included three components: i) goal setting with The Canadian Occupational Performance Measure (COPM), ii) provided support to home care staff to enhance their provision of reablement, and iii) explored the incorporation and use of an information- and communication technology (ICT) to facilitate information transfer. RESULTS: Using COPM for goal setting with older adults and providing support to the staff via workshops were valuable components in the delivery of ASSIST 1.0. The ICT product encountered several challenges and could not be evaluated. COPM and EQ-5D were deemed the most important instruments. Organisational and political barriers affected the feasibility. Although, the fidelity and adherence were complied the staff perceived the program to be acceptable. CONCLUSION: The ASSIST 1.0 program was feasible in regard of study design, delivering the intervention, and evaluating instruments that detected a change. A logical progression would be to conduct a full-scale trial. In addition, a usability study to evaluate the technological component is also recommended. With minor improvements, the ASSIST 1.0 program has the potential to contribute to the development of a home care organisation that could enhance older adults possibility to age in place at home.

Engagement in Everyday Activities for Prevention of Stroke: Feasibility of an mHealth-Supported Program for People with TIA.

Most of the risk factors for stroke are modifiable, yet incorporating and sustaining healthy lifestyle habits in daily life that reduce these risk factors is a major challenge. Engaging everyday activities (EEAs) are meaningful activities that are regularly performed that have the potential to contribute to the sustainability of healthy lifestyle habits and reduce risk factors for stroke. The aims of this study were (1) to investigate the feasibility and acceptability of a digitally supported lifestyle program called "Make My Day" (MMD) for people at risk for stroke following a transient ischemic attack, and (2) to describe participants' stroke risk and lifestyle habits pre- and post-intervention. A multiple case study design using mixed methods was utilized (n = 6). Qualitative and self-reported quantitative data were gathered at baseline, post-intervention, and 12 months post-baseline. The results indicate that MMD can support lifestyle change and self-management for persons at risk for stroke following a TIA. The findings indicate a high acceptability and usability of MMD, as well as a demand for digital support provided via a mobile phone application. Self-management with digital support has the potential to increase participation in EEAs for persons at risk for stroke following a TIA.

Occupational therapists' perceptions of implementing a client-centered intervention in close collaboration with researchers: A mixed methods study.

Background: Integration of research-based knowledge in health care is challenging. Occupational therapists (OTs) need to implement new research-based interventions in clinical practice. Therefore it is crucial to recognize and understand the factors of specific barriers and facilitators affecting the implementation process.Aim: To identify the key factors important for OTs during the implementation process of a complex intervention.Materials and methods: A cross-sectional study with a combination of qualitative and quantitative data in a mixed method design. Forty-one OTs and 23 managers from three county councils in Sweden, responded to a questionnaire one year after the OTs participation in a workshop to prepare for implementation of a client-centered activity of daily living intervention for persons with stroke.Results: Over 70% of the OTs benefitted from reading and discussing articles in the workshop; 60% had faith in the intervention; 69% reported usability of the intervention. High level of support from managers was reported, but less from team members. The therapists' interaction, perceptions of own efforts and contextual influence affected the implementation process.Conclusion: The workshop context with facilitation and access to evidence, supportive organizations and teams, sufficient interaction with researchers and satisfying self-image were successful key factors when involved in research.

Primary prevention of stroke: randomised controlled pilot trial protocol on engaging everyday activities promoting health.

INTRODUCTION: Stroke is a globally common disease that has detrimental effects on the individual and, more broadly, on society. Lifestyle change can contribute to reducing risk factors for stroke. Although a healthy lifestyle has direct benefits, sustaining and incorporating healthy activities into everyday life is a challenge. Engaging everyday activities have the potential to support lifestyle change and to promote sustainable activity patterns. Current healthcare is failing to reduce modifiable risk factors in people at risk, and in addition to current practice, there is a need for systematic and efficient non-pharmacological and non-surgical stroke-prevention strategies. The aim of the pilot study was to increase knowledge about the effects of a prevention programme and its feasibility to promote sustainable and healthy activity patterns among persons at risk of stroke. METHODS AND ANALYSIS: The proposed pilot study will be a two-armed randomised, assessor-blinded, parallel pilot trial. The study will include feasibility data, investigating acceptability and delivery of the intervention. Persons at risk of stroke (n=60) will be included in a mobile phone-supported prevention programme. The 10-week programme will be conducted at primary healthcare clinics, combining group meetings and online resources to support self-management of lifestyle change. Main outcomes are stroke risk, lifestyle habits and healthy activity patterns. Assessments will be performed at baseline and at follow-up (immediately following the end of the programme and at 6 and 12 months). Effects of the programme will be analysed using inferential statistics. Feasibility will be analysed using both qualitative and quantitative methods. ETHICS AND DISSEMINATION: The study has been approved by the Regional Ethical Review Board in Stockholm, Sweden, being granted reference numbers 2015/834-31, 2016/2203-32 and 2019/01444. Study results will be disseminated through peer-review journals and presentations to mixed audiences at regional and international conferences. TRIAL REGISTRATION NUMBER: NCT03730701.

Occupational therapists experiences of implementing a new complex intervention in collaboration with researchers: a qualitative longitudinal study.

BACKGROUND: This study was conducted in the context of a randomized controlled trial where occupational therapists (OTs) in collaboration with researchers implemented a client-centred activity of daily living intervention (CADL) for persons with stroke. OBJECTIVE: The aim was to identify and describe over time the OTs' experiences regarding the collaboration with the researcher in their role as implementers of a new complex intervention. METHOD: Focus group interviews were conducted with 33 OTs, two, six and 12 months after they had participated in a five-day workshop. The interviews were analysed using a grounded theory approach. RESULTS: Three categories were identified: (1) Including in the scientific world, (2) Involving as an implementer of science and (3) Integrating in a partnership. One core category emerged: The implementation of client-centred intervention enabled the fusion of practice and science. An increased experience of using CADL and support from the researchers changed the OTs' attitudes towards engaging in research from being an outsider to the scientific world to being included and then becoming a part of the research as an implementer of science. CONCLUSIONS: To create a context built on a collaborative partnership between practitioners and researchers enabled the fusion of practice and science.

General movements and magnetic resonance imaging in the prediction of neuromotor outcome in children born extremely preterm.

BACKGROUND: Extremely preterm (EPT) birth is a major risk factor for brain injury and neurodevelopmental impairment. Reliable tools for early prediction of outcome are warranted. AIM: To investigate the predictive value of general movements (GMs) at "fidgety age" for neurological outcome at age 30 months in EPT infants, both in comparison and in combination with structural magnetic resonance imaging (MRI) at term equivalent age (TEA). STUDY DESIGN: Fifty-three infants born <27 weeks of gestation were included prospectively. MRI was performed at TEA and images were evaluated for white and grey matter abnormalities. GMs were assessed at age 3 months corrected ("fidgety age"). OUTCOME MEASURES: Neuromotor outcome was assessed at age 30months corrected. Children were classified as having a normal neurological status, unspecific signs, or cerebral palsy (CP). RESULTS: Abnormal GMs were a common finding, seen in 32% (17/53) of infants. Of these, six infants (11%) had definitely abnormal GMs. Four infants (8%) had a diagnosis of CP at follow up. Definitely abnormal GMs were significantly associated to CP at 30 months (Fisher's Exact test p=0.03, sensitivity 50%, specificity 92%). Moderate-severe white matter abnormalities on MRI were more strongly associated with CP (Fisher's Exact test p<0.001, sensitivity 100%, specificity 98%) than GMs. Combining GMs with MRI-findings at TEA increased the predictive specificity to 100% (Fisher's Exact test, p=0.005), whereas sensitivity remained unchanged. CONCLUSIONS: The presence of definitely abnormal GMs was predictive of CP: prediction was significantly enhanced when the GMs assessment was combined with findings from MRI obtained at TEA.

Occupational therapists' experiences in integrating a new intervention in collaboration with a researcher.

OBJECTIVE: The aim of this study was to describe occupational therapists' expectations and experiences of integrating a new intervention programme within an RCT pilot study, in collaboration with a researcher. METHODS: Six occupational therapists participated in a five-day training course (during a one-month period) including lectures, reading articles, and discussions. The data were collected through interviews and written reflections, analysed by a qualitative constant comparative approach. RESULTS: The findings displayed a process of change, primarily in the participants' way of integrating research in their clinical practice. Three main categories were identified as: hope of taking part in a research project, confirmation of anchoring, and experience of scepticism. These categories constituted the core category "The occupational therapist's process of integrating research in a clinical context with the prerequisite being a dialogue and a sharing of responsibility and authority between researcher and occupational therapist". A tentative model was formulated which described how the various categories were related to one another as well as how change occurred over time in the context in which the study was carried out. CONCLUSIONS: One conclusion is the importance of providing opportunities for creating dialogues among researcher and practitioners to narrowing the gap between research and "everyday practice of occupational therapy".

Evaluation of nasal barrier dysfunction at acute- and late-phase reactions in a guinea pig model of allergic rhinitis.

Allergic rhinitis is a common disease characterized by the symptoms of pruritus, sneezing, hypersecretion and nasal blockage. Increased mucosal barrier permeability has been suggested to be an indicator for the severity of allergic rhinitis. This study investigates the passage of radiolabelled albumin from the nasal mucosal circulation into the lumen in guinea pigs intraperitoneally sensitized and intranasally challenged with antigen. In order to characterize the allergic rhinitis model, we evaluated a number of potential influencing factors in nasal plasma exudation, including antigen doses, volumes of antigen solution used, and animal position during the nasal lavage, and the conditions of nasal lavage. The number of eosinophils and levels of histamine and leukotriene B4 in the nasal lavage and eosinophils in the nasal mucosa were determined at the early and late phases after antigen challenge. We also compared the effects of topical nasal treatments for allergic rhinitis on nasal inflammatory responses. Our results demonstrate that, in the guinea pig nasal mucosa, topical challenge with antigens induces plasma exudation and histamine release at the acute-phase reaction, and plasma exudation and eosinophil infiltration at the late-phase reaction. These changes are similar to those reported in human allergic rhinitis. Alterations of nasal plasma exudation, histamine release and eosinophil influx were dependent upon the concentrations and volumes of antigens. An antihistamine inhibited the acute-phase reaction partially, whereas budesonide inhibited effects at the late-phase reaction. We suggest that this model of guinea pig allergic rhinitis with the early and late responses may be useful for high-throughout screening of new drugs.

Effects of budesonide and N-acetylcysteine on acute lung hyperinflation, inflammation and injury in rats.

Leukocyte activation and production of inflammatory mediators and reactive oxygen species are important in the pathogenesis of lipopolysaccharide (LPS)-induced acute lung injury. The present study investigated acute lung hyperinflation, edema, and lung inflammation 4 h after an intratracheal instillation of LPS (0.5, 2.5, 5, 10, 50, 100, 500, 1000, and 5000 microg/ml/kg). Effects of budesonide, an inhaled anti-inflammatory corticosteroids, and N-acetylcysteine (NAC), an antioxidant, were evaluated in Wistar rats receiving either low (2.5 microg/ml/kg) or high (50 microg/ml/kg) concentrations of LPS. This study demonstrates that LPS in a concentration-dependent pattern induces acute lung hyperinflation measured by excised lung gas volume (25-45% above control), lung injury indicated by increased lung weight (10-60%), and lung inflammation characterized by the infiltration of leukocytes (40-14000%) and neutrophils (80-17000%) and the production of cytokines (up to 2700%) and chemokines (up to 350%) in bronchoalveolar lavage fluid (BALF). Pretreatment with NAC partially prevented tumor necrosis factor alpha (TNFalpha) production induced by the low concentration of LPS, while pretreatment with budesonide totally prevented the increased production of TNFalpha, interleukin (IL)-1beta, IL-6, and monocyte chemoattractive protein (MCP)-1 after LPS challenge at both low and high concentrations. Budesonide failed to prevent BALF levels of macrophage inflammatory protein (MIP)-2 and cytokine-induced neutrophil chemoattractant 1 (GRO/CINC-1) as well as lung hyperinflation induced by both low and high concentrations of LPS. Pretreatment with budesonide totally prevented the formation of lung edema at the low concentration of LPS and had partial effects on acute lung injury and leukocyte influx at the high concentrations. Thus, our data indicate that therapeutic effects of budesonide and NAC are dependent upon the severity of the disease.

Interleukin-2-inducible T cell kinase regulates mast cell degranulation and acute allergic responses.

Bruton's tyrosine kinase (Btk) is thought to positively regulate mast cell activation, implying a role in allergic responses. We have compared acute and late phase allergic airway reactions in mice lacking either Btk or interleukin-2-inducible T cell kinase (Itk), another Tec kinase expressed in mast cells. Btk(-/-) mice showed minor protection against allergic symptoms when challenged with allergen via the airways. In sharp contrast, both acute and late phase inflammatory allergic responses were markedly reduced in Itk(-/-) mice. Notably, airway mast cell degranulation in Itk(-/-) mice was severely impaired, despite wild-type levels of allergen-specific IgE and IgG1. The degranulation defect was confirmed in DNP-conjugated human serum albumin-challenged mice passively sensitized with anti-DNP IgE antibodies, and was also observed after direct G-protein stimulation with the mast cell secretagogue c48/80. Moreover, late phase inflammatory changes, including eosinophilia, lymphocyte infiltration, and Th2 cytokine production in the lungs, was eliminated in Itk(-/-) mice. Collectively, our data suggest a critical role of Itk in airway mast cell degranulation in vivo that together with an impaired T cell response prevents the development of both acute and late phase inflammatory allergic reactions.

Lung inflammatory responses and hyperinflation induced by an intratracheal exposure to lipopolysaccharide in rats.

Exposure of the respiratory tract to lipopolysaccharide (LPS) induces acute local inflammation and tissue injury associated with the various deliveries of LPS. To determine potential association of local inflammatory responses with respiratory tract dysfunction, infiltration of inflammatory cells, production of inflammatory mediators, lung hyperinflation and edema were measured in Wister rats 2, 4, and 24 h after an intratracheal administration of LPS at different doses (5, 50, 500 and 5000 microg/ml/kg). Lung hyperinflation determined by an increased excised lung gas volume was significantly increased 2 and 4 h after LPS instillation and lung edema occurred from 2 h onward. Peak BAL levels of TNFalpha appeared at 2 h, MCP-1 at 4 h, and IL-6 at 2 and 4 h, while BAL levels of IL-1beta were increased during 24 h after the intratracheal instillation of LPS. Neutrophilia in BAL fluid was noted from 2 h post-challenge. Our results demonstrate a clear dose-related change in the lung weight at 4 and 24 h, in the BAL levels of MCP-1 at 4 h, and IL-6 and IL-1beta at 2 and 4 h. It seems important to understand polymorphisms of LPS-induced lung hyperinflation and inflammation. Lung hyperinflation and inflammation may be independent during the development of acute lung injury.
