Access to urban green spaces and use of social services and institutional long-term care among older people in Malmö, Sweden: a longitudinal register study.

BACKGROUND: Finding ways to prolong independence in daily life among older people would be beneficial for both individuals and society. Urban green spaces have been found to improve health, but only a few studies have evaluated the association between urban green spaces and independence in daily life. The aim of this study was to assess the long-term effect of urban green spaces on independence in daily life, using social services and support, mobility aids, and relocation to institutional long-term care as proxies, among community dwelling people 65 + years. METHODS: We identified 40 357 people 65 + years living in the city of Malmö, Sweden in 2010. Using geographical information systems (GIS), we determined the amount of urban green spaces (total, public, and quiet) within 300 m of each person's residence. All three measures were categorized based on their respective percentiles, so that the first quartile represented the 25% with the least access and the fourth quartile the 25% with the most access. In 2015 and 2019, we assessed the outcomes minor assistance (non-personal support), major assistance (personal support), and relocation into institutional long-term care. These three outcome measures were used as proxies for independence in daily life. The effect of amount of urban green spaces in 2010 on the three outcomes in 2015 and 2019, respectively, was assessed by pairwise comparing the three highest quartiles to the lowest. RESULTS: Compared to the lowest quartile, those in the highest quartile of quiet green spaces in 2010 were less likely to receive minor assistance in both 2015 and 2019. Besides this, there were no indications that any of the measures of urban green space affected independence in daily life at the five- and nine-year follow-up, respectively. CONCLUSION: Although urban green spaces are known to have positive impact on health, physical activity, and social cohesion among older people, we found no effect of total, public, or quiet green spaces on independence in daily life. This could possibly be a result of the choice of measures of urban green spaces, including spatial and temporal aspects, an inability to capture important qualitative aspects of the green spaces, or the proxy measures used to assess independence in daily life.

'Normality in all the abnormality'-Older adults' experiences of holidays and celebrations from the COVID-19 pandemic.

INTRODUCTION: The importance of holidays, traditions, and family celebrations to human culture and occupational engagement has been neglected. The aim of this study was to explore how older adults experienced holidays and celebrations with social and physical distancing during the COVID-19 pandemic. METHODS: A secondary analysis was made on data from the At-Risk Study. Seventeen community-living adults (11 women and 6 men) aged 71-87 years, from Sweden participated. They were interviewed remotely four times during the first year of the pandemic. Data were analysed with qualitative content analysis. No consumer/community involvement occurred. FINDINGS: Three categories on how the participants hoped for, planned, decided, adapted, avoided, and experienced holidays and celebrations with social and physical distancing included expectations and preparations in unpredictable times; the constant need for re-evaluation; and almost everything turned out differently. CONCLUSIONS: The desire to celebrate despite pandemic restrictions shows the importance and meaning holidays hold for older adults. Celebrations can be disrupted for many reasons, not only as extreme as the ongoing pandemic. For wellbeing in later life health care, social care, and society need to understand the inherent components and acknowledge ways of supporting participation in occasional events such as holidays, traditions, and family celebrations.

Using sensor-based technology for safety and independence - the experiences of people with dementia and their families.

BACKGROUND: The majority of people with dementia prefer to live independently and safely in their own home cared for by their family members. Much effort has been invested in the development of technology, such as sensor-based networks. Many challenges remain, in particular gaining more knowledge about their experiences and perceived benefits. This study aimed to explore experiences, needs and benefits with using sensor-based technology for safety and independence in the homes of people with dementia and their family members. METHODS: This study is part of the TECH@HOME project, aiming to evaluate the effects of sensor-based technology on independence among people with dementia and caregiver stress among their family members. This study applied an inductive, qualitative approach with semi-structured interviews of people with dementia (n = 9) and family members (n = 21). The participants were interviewed between June and September 2018 after using the technology for at least 6 months. The interviews were analysed with manifest content analysis. RESULTS: Our findings highlighted that technology was considered as a precaution and a safety measure that could provide a sense of having control of the everyday life of the person with dementia. Understanding and acceptance of the technology were as important, together with the reliability of the technology. Ethical dilemmas related to the monitoring of the person with dementia in the home were also raised. CONCLUSION: This study provides insights into how people with dementia and family members experience and benefit from using sensor-based technology in their own homes. The knowledge generated is essential for healthcare professionals and policymakers developing and implementing care and service systems including technology, as well as for the industry.

Healthcare professionals' lived experiences of conversations with young adults expressing existential concerns.

INTRODUCTION: This paper describes first-line department healthcare professionals' experiences of conversations with young adults (16-25 years) who express existential concerns. Existential concerns encompass questions about the meaning of life and the choices people must make, and they are sometimes expressed during the period in which a child is becoming an adult. Sometimes the transition to adulthood can be difficult, and many young adults seek support from people in first-line departments, such as primary care providers, youth guidance centre personnel and student health service employees in high schools and universities. Conversations in which existential concerns are recognised may be important for preventing mental illness in the future. AIM: The study aimed to describe healthcare professionals' lived experiences of conversations with young adults who express existential concerns. APPROACH AND METHODS: This qualitative study utilises thematic meaning analysis. Interviews were conducted with healthcare professionals working in first-line departments, and data were analysed based on the principles of reflective lifeworld research. The study followed ethical codes of conduct and conformed to the ethical guidelines adopted by the Swedish Research Council. FINDINGS: The results are presented in three themes of meaning: searching for innermost thoughts requires being present, uncertainty about the unpredictable and awakening of one's own existential concerns. CONCLUSIONS AND IMPLICATIONS: Healthcare professionals are affected when young adults express their existential concerns, and they need more support to strengthen their ability to stay present and create inviting atmospheres.

The elusive ligand complexes of the DWARF14 strigolactone receptor.

Strigolactones, a group of terpenoid lactones, control many aspects of plant growth and development, but the active forms of these plant hormones and their mode of action at the molecular level are still unknown. The strigolactone protein receptor is unusual because it has been shown to cleave the hormone and supposedly forms a covalent bond with the cleaved hormone fragment. This interaction is suggested to induce a conformational change in the receptor that primes it for subsequent interaction with partners in the signalling pathway. Substantial efforts have been invested into describing the interaction of synthetic strigolactone analogues with the receptor, resulting in a number of crystal structures. This investigation combines a re-evaluation of models in the Protein Data Bank with a search for new conditions that may permit the capture of a receptor-ligand complex. While weak difference density is frequently observed in the binding cavity, possibly due to a low-occupancy compound, the models often contain features not supported by the X-ray data. Thus, at this stage, we do not believe that any detailed deductions about the nature, conformation, or binding mode of the ligand can be made with any confidence.

Experiences of fear of falling in persons with Parkinson's disease - a qualitative study.

BACKGROUND: Fear of falling is common among persons with Parkinson's disease and is negatively associated with quality of life. However a lack of in-depth understanding of fear of falling as a phenomenon persists. This qualitative study aimed to explore the experiences of fear of falling in persons with Parkinson's disease. METHODS: Individual interviews were performed with twelve persons with Parkinson's disease (median age 70 years, median Parkinson duration 9 years, 50% women). The interviews were semi-structured and followed a study-specific interview guide. The transcribed interviews were analyzed using qualitative content analysis. RESULTS: Fear of falling was experienced as a disturbing factor in everyday life. It generated a feeling of vulnerability and made daily activities and everyday environments seem potentially hazardous. Persons also missed performing previous activities. The fear of falling was a varying experience, fueled by an awareness of falls and near falls, Parkinson-related symptoms and disabilities, and by others in their environment. The persons adopted different strategies to handle their fear of falling. Activities were adapted, avoided, performed with help, or carried out despite their fear of falling. CONCLUSIONS: The experiences of fear of falling were complex, multifaceted and varied over time and in relation to different activities and environments. This indicates that interventions targeting fear of falling need to be individually tailored for persons with Parkinson's disease and should focus on several aspects, such as Parkinson-related symptoms and disabilities, activities and environmental factors. This study provides new information that increases the understanding of fear of falling, which has implications for researchers as well as clinicians working with persons with Parkinson's disease and fear of falling.

The Perception of Physical Activity in Ambulatory Persons with Late Effects of Polio: A Qualitative Study.

Maintaining regular physical activity (PA) can be challenging for persons with late effects of polio. This qualitative study of ambulatory persons with late effects of polio explored their perceptions of PA, as well as facilitators of and barriers to PA. Semistructured interviews were conducted with 15 persons and analyzed with content analysis using the International Classification of Functioning, Disability and Health (ICF) as a framework. The participants described positive perceptions of PA and its health benefits. PA was used to prevent further decline in functioning, and the type and frequency of activities had changed over time. Past experiences and personal characteristics impacted PA. Support from close relatives, knowledgeable health care professionals, mobility devices, and accessible environments facilitated PA, whereas impairments, inaccessible environments, and cold weather were the main barriers. To perform PA regularly, persons with late effects of polio may benefit from individualized advice based on their disability and personal and environmental factors.

Typology of person-environment fit constellations: a platform addressing accessibility problems in the built environment for people with functional limitations.

BACKGROUND: Making the built environment accessible for all regardless of functional capacity is an important goal for public health efforts. Considerable impediments to achieving this goal suggest the need for valid measurements of acccessibility and for greater attention to the complexity of person-environment fit issues. To address these needs, this study aimed to provide a methodological platform, useful for further research and instrument development within accessibility research. This was accomplished by the construction of a typology of problematic person-environment fit constellations, utilizing an existing methodology developed to assess and analyze accessibility problems in the built environment. METHODS: By means of qualitative review and statistical methods we classified the person-environment fit components covered by an existing application which targets housing accessibility: the Housing Enabler (HE) instrument. The International Classification of Functioning, Disability and Health (ICF) was used as a conceptual framework. Qualitative classification principles were based on conceptual similarities and for quantitative analysis of similarities, Principal Component Analysis was carried out. RESULTS: We present a typology of problematic person-environment fit constellations classified along three dimensions: 1) accessibility problem range and severity 2) aspects of functioning 3) environmental context. As a result of the classification of the HE components, 48 typical person-environment fit constellations were recognised. CONCLUSIONS: The main contribution of this study is the proposed typology of person-environment fit constellations. The typology provides a methodological platform for the identification and quantification of problematic person-environment fit constellations. Its link to the globally accepted ICF classification system facilitates communication within the scientific and health care practice communities. The typology also highlights how relations between aspects of functioning and physical environmental barriers generate typical accessibility problems, and thereby furnishes a reference point for research oriented to how the built environment may be designed to be supportive for activity, participation and health.

Physical Activity and the Association With Self-Reported Impairments, Walking Limitations, Fear of Falling, and Incidence of Falls in Persons With Late Effects of Polio.

The purpose of this study was to determine the association between physical activity and self-reported disability in ambulatory persons with mild to moderate late effects of polio (N = 81, mean age 67 years). The outcome measures were: Physical Activity and Disability Survey (PADS), a pedometer, Self-Reported Impairments in Persons with Late Effects of Polio Scale (SIPP), Walking Impact Scale (Walk-12), Falls Efficacy Scale-International (FES-I), and self-reported incidence of falls. The participants were physically active on average 158 min per day and walked 6,212 steps daily. Significant associations were found between PADS and Walk-12 (r = -.31, p < .001), and between the number of steps and SIPP, Walk-12, and FES-I (r = -.22 to -.32, p < .05). Walk-12 and age explained 14% of the variance in PADS and FES-I explained 9% of the variance in number of steps per day. Thus, physical activity was only weakly to moderately associated with self-reported disability.

Structure of the homodimeric glycine decarboxylase P-protein from Synechocystis sp. PCC 6803 suggests a mechanism for redox regulation.

Glycine decarboxylase, or P-protein, is a pyridoxal 5'-phosphate (PLP)-dependent enzyme in one-carbon metabolism of all organisms, in the glycine and serine catabolism of vertebrates, and in the photorespiratory pathway of oxygenic phototrophs. P-protein from the cyanobacterium Synechocystis sp. PCC 6803 is an α2 homodimer with high homology to eukaryotic P-proteins. The crystal structure of the apoenzyme shows the C terminus locked in a closed conformation by a disulfide bond between Cys(972) in the C terminus and Cys(353) located in the active site. The presence of the disulfide bridge isolates the active site from solvent and hinders the binding of PLP and glycine in the active site. Variants produced by substitution of Cys(972) and Cys(353) by Ser using site-directed mutagenesis have distinctly lower specific activities, supporting the crucial role of these highly conserved redox-sensitive amino acid residues for P-protein activity. Reduction of the 353-972 disulfide releases the C terminus and allows access to the active site. PLP and the substrate glycine bind in the active site of this reduced enzyme and appear to cause further conformational changes involving a flexible surface loop. The observation of the disulfide bond that acts to stabilize the closed form suggests a molecular mechanism for the redox-dependent activation of glycine decarboxylase observed earlier.

Explosion dynamics of sucrose nanospheres monitored by time of flight spectrometry and coherent diffractive imaging at the split-and-delay beam line of the FLASH soft X-ray laser.

We use a Mach-Zehnder type autocorrelator to split and delay XUV pulses from the FLASH soft X-ray laser for triggering and subsequently probing the explosion of aerosolised sugar balls. FLASH was running at 182 eV photon energy with pulses of 70 fs duration. The delay between the pump-probe pulses was varied between zero and 5 ps, and the pulses were focused to reach peak intensities above 10¹6W/cm² with an off-axis parabola. The direct pulse triggered the explosion of single aerosolised sucrose nano-particles, while the delayed pulse probed the exploding structure. The ejected ions were measured by ion time of flight spectrometry, and the particle sizes were measured by coherent diffractive imaging. The results show that sucrose particles of 560-1000 nm diameter retain their size for about 500 fs following the first exposure. Significant sample expansion happens between 500 fs and 1 ps. We present simulations to support these observations.

A research-based strategy for managing housing adaptations: study protocol for a quasi-experimental trial.

BACKGROUND: The primary aim of this paper is to describe the design of a project evaluating the effects of using a research-based strategy for managing housing adaptations (HAs). The evaluation targets clients' perspectives in terms of activity, participation, usability, fear of falling, fall incidence, use of mobility devices, and health-related quality of life, and determines the societal effects of HAs in terms of costs. Additional aims of the project are to explore and describe this strategy in relation to experiences and expectations (a) among clients and cohabitants and (b) occupational therapists in ordinary practice. METHODS/DESIGN: This study is a quasi-experimental trial applying a multiphase design, combining quantitative and qualitative data. At the experimental sites, the occupational therapists (OTs) apply the intervention, i.e. a standardized research-based strategy for HA case management. At the control site, the occupational therapists are following their regular routine in relation to HA. Three municipalities in south Sweden will be included based on their population, their geographical dispersion, and their similar organizational structures for HA administration. Identical data on outcomes is being collected at all the sites at the same four time points: before the HA and then 3, 6, and 12 months after the HA. The data-collection methods are semi-structured qualitative interviews, observations, clinical assessments, and certificates related to each client's HA. DISCUSSION: The intervention in this study has been developed and tested through many years of research and in collaboration with practitioners. This process includes methodological development and testing research aimed at identifying the most important outcomes and research targeting current HA case-management procedures in Swedish municipalities. When the study is completed, the results will be used for further optimization of the practice strategy for HA, in close collaboration with the data-collecting OTs. TRIAL REGISTRATION: No: NCT01960582.

Existential vulnerability can be evoked by severe difficulties with initial breastfeeding: a lifeworld hermeneutical single case study for research on complex breastfeeding phenomena.

Many mothers initiate breastfeeding, but some of these experience difficulties. This study has two aims in order to contribute to the development of optimal care for these mothers: firstly to explain and understand the existential meanings of one mother's severe initial breastfeeding difficulties and how these meanings affected her continued breastfeeding and secondly, to reflect on a method for applying lifeworld hermeneutics to research on complex breastfeeding phenomena. This is an approach that acknowledges and focuses on the concrete and lived existence and what it means for humans. Within this approach, humans are understood as whole human beings interacting in the world. The study was conducted using lifeworld interviews with Anna, focusing on meanings of her difficult lived experience of initial breastfeeding. The existential interpretation suggests that such an experience can evoke existential vulnerability, a vulnerability that becomes evident in shameful feelings, such as dislike of breastfeeding, aversion to the milk-producing body and anger towards the child. Anna continued breastfeeding as a way to rid herself of the shame, hoping to be confirmed as a good mother. Such an experience may have negative consequences for the mother-child relationship and it can create fear for future breastfeeding. This study concludes that carers should be aware of individual existential dimensions for breastfeeding mothers.

The Egress Enabler: Development and psychometric evaluation of an instrument to measure egressibility.

BACKGROUND: Egressibility has been defined as a person-environment fit issue and describes accessibility to means of evacuation. Although egressibility concerns everyone, it has become a useful concept particularly in relation to safety and accessibility for people with functional limitations, commonly highlighted as a vulnerable group in egress scenarios. Egressibility is an important safety factor, but there has been limited efforts trying to quantify it. OBJECTIVE: The aim has been to develop an instrument to measure egressibility in public buildings, as well as conducting initial psychometric testing of the instrument. METHODS: The Egress Enabler is based on the previously developed Housing Enabler instrument. The Egress Enabler was developed in several steps by an interdisciplinary team, incorporating an expert panel and a case study. RESULTS: Evaluation of content validity was in line with previous similar efforts, inter-rater reliability was considered "good" to "excellent" by means of intraclass correlation, and qualitative assessment of construct validity showed theoretically sound results. CONCLUSIONS: It is suggested that an instrument like the Egress Enabler is needed for a systematic evaluation of egressibility during design. construction or operation. This is needed for ensuring equal access to egress for people with functional limitations.

Estimation of the amount of ß2-glycoprotein I adsorbed at the inner surface of fused silica capillaries after acidic, neutral and alkaline pretreatment.

Sample adsorption to the inner surface of fused silica capillaries is a common problem in CE when analyzing macromolecules and is harmful to the analysis. We previously utilized the pH hysteresis effect of fused silica to facilitate electrophoresis of the strongly adsorbing protein ß(2) gpI in plain-fused silica capillaries at neutral pH. In the present paper, the effect of different pretreatments of the capillary on the adsorption of the ß(2) -glycoprotein I has been investigated using electroosmosis markers, SDS mobilization, and imaging based on indirect immunofluorescence microscopy for direct visualization. The amount of ß(2) gpI adsorbed on the surface was probed using all these independent techniques after electrophoresis at neutral pH on capillaries pretreated with HCl, background electrolyte (BGE), and NaOH. BGE pretreatment was included as a positive control. We found that 80% or more of the starting material was adsorbed to the inner surface of the silica capillaries during electrophoresis after pretreatment with only BGE or with NaOH, but after acidic pretreatment the loss was consistently less than 20%. NaOH most efficiently removes adsorbed protein between runs. A theoretical calculation of the pH change of the BGE showed that electrolysis affects the pH more than the deprotonation of silanols during electrophoresis. We conclude that acidic pretreatment of fused silica capillaries diminishes adsorption of ß(2) gpI by decreasing charge-dependent wall adsorption.

The paradox of being both needed and rejected: the existential meaning of being closely related to a person with bipolar disorder.

The aim of this study was to elucidate the existential meaning of being closely related to a person with bipolar disorder. A qualitative, descriptive, and explorative design with a phenomenological meaning-oriented analysis was used. The findings reveal a paradoxical, existential exposure of close relatives to a person with bipolar disorder, being both needed and rejected whilst being overshadowed by the specific changeable nature of bipolar disorder. Psychiatric health care services are recommended to consider changes in attitudes and structures that may facilitate close relatives' participation in the care and treatment of persons with bipolar disorder.

Changes in daily life and wellbeing in adults, 70 years and older, in the beginning of the COVID-19 pandemic.

BACKGROUND: In the beginning of the COVID-19 pandemic, Swedish authorities enforced specific recommendations on social distancing for adults 70 years and older (70+). Day-to-day life changed for 15% of the Swedish population. The aim of the study was to explore how adults 70+ experienced and managed changes in everyday life due to the COVID-19 pandemic and how those changes affected wellbeing at the beginning of the virus outbreak. METHODS: Eleven women and six men, (mean age 76 years), living in ordinary housing, participated in remote semi-structured interviews in April 2020. The interviews were analysed with qualitative content analysis. FINDINGS: The theme Suddenly at risk - '…but it could have been worse' included four categories My world closed down; Negotiations, adaptations and prioritizations to manage staying at home; Barriers and facilitators to sustain occupational participation; and Considerations of my own and other's health and wellbeing emerged from the data analysis. CONCLUSION: Everyday life changes had implications for health and well-being. The participants questioned previous conceptions of meaning in relation to habitual activities, likely leading to consistent occupational changes. However, these long-term effects remain to be explored, and considered to enable older adult's health during the pandemic and beyond.

'Are they really allowed to treat me like that?' - A qualitative study to explore the nature of formal patient complaints about mental healthcare services in Sweden.

The improvement of mental healthcare services requires patients' experiences to identify problems and possible deficits in care. In this study, we explored the nature and meaning of formal patient complaints about mental healthcare services in one region of Sweden using a descriptive design with a qualitative approach. A systematic random sample of 106 formal patient complaints about mental healthcare services in 1 Swedish county was selected and analysed thematically, based on descriptive phenomenology. Themes identified were: lack of access to mental healthcare services and specialist treatment, problems related to unmet needs and difficulties with healthcare staff, insufficient care and treatment and lack of continuity in care, and experiences of not been taken seriously or feeling abused by staff. The vulnerability of patients already in the system is a greater issue than realized. The human right to health and the healthcare of patients with mental ill health can be strengthened by increased access to care, listening to patients properly, and delivering continuity in care.

Finding an existential place to rest: enabling well-being in young adults.

What enables well-being when experiencing existential concerns as a young adult is an under-explored area of research. In order to address young adults' existential concerns and provide caring support that builds their resilience to meet life challenges, the purpose of the study is to describe the meaning of enabling well-being as experienced by young adults living with existential concerns. This phenomenological study is based on a reflective lifeworld research. Seventeen young adults, aged 17-27 years, were interviewed. The results is presented in an essential meaning and further explored with its variations and individual nuances of the phenomenon; enabling well-being. The essential meaning of enabling well-being, when experiencing existential concerns as a young adult, means finding a place to rest. Finding a place to rest means finding both movement and stillness in life to reflect upon one's life story in order to understand oneself. The results also show that young adults enable their own well-being in many ways when experiencing existential concerns. When their existential concerns feel overwhelming, they need support from healthcare professionals. When young adults seek professional support, the professionals must be open and focus on the young adults' life story to enable well-being.

Impact of Sociodemographic Factors on Use of Formal Social Services in an Older Swedish Population.

BACKGROUND: In Sweden, societal support for older people is the responsibility of the municipalities. However, due to Sweden's current aging-in-place policy for older people, there is a need to assess how the use of such services varies based on sociodemographic factors. The aim of this study was to describe the use of different forms of social services and institutional long-term care (ILTC) in an older population and to evaluate the impact of sociodemographic factors. METHODS: This was a cross-sectional register-based study, including all individuals aged 65 years and older in two Swedish municipalities in 2010, 2015, and 2019. The study analyzed the use of social services and ILTC in relation to sex, place of birth, cohabitation status, and type of housing. RESULTS: Women, those born in Sweden, and those living in an apartment were more likely to receive assistance than men, those born abroad, or living in single family houses, respectively. People living alone were consistently more likely to have assistance, as well as ILTC. CONCLUSIONS: There may be a discrepancy between the individual's need and the assistance provided from the municipality in certain sociodemographic groups in the older population in Sweden.
