    The Effects of the Digital Platform Support Monitoring and Reminder Technology for Mild Dementia (SMART4MD) for People With Mild Cognitive Impairment and Their Informal Carers: Protocol for a Pilot Randomized Controlled Trial2019Ingår i: JMIR Research Protocols, ISSN 1929-0748, E-ISSN 1929-0748, Vol. 8, nr 6, artikel-id e13711Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Many countries are witnessing a trend of growth in the number and proportion of older adults within the total population. In Europe, population aging has had and will continue to have major social and economic consequences. This is a fundamentally positive development where the added life span is of great benefit for both the individual and the society. Yet, the risk for the individual to contract noncommunicable diseases and disability increases with age. This may adversely affect the individual's ability to live his or her life in the way that is desired. Cognitive conditions constitute a group of chronic diseases that predominantly affects older people. Recent technology advancements can help support the day-to-day living activities at home for people with cognitive impairments. Objective: A digital platform (Support Monitoring and Reminder for Mild Dementia; SMART4MD) is created to improve or maintain the quality of life for people with mild cognitive impairment (PwMCI) and their carers. The platform will provide reminders, information, and memory support in everyday life, with the purpose of giving structure and lowering stress. In the trial, we will include participants with a diagnosed neurocognitive disorder as well as persons with an undiagnosed subjective memory problem and cognitive impairment, that is, 20 to 28 points on the Mini-Mental State Examination. Methods: A pragmatic, multicenter RCT is being conducted in Spain, Sweden, and Belgium. The targets for recruitment are 1200 dyads-split into an intervention group and a control group that are in usual care. Intervention group participants will be provided with a data-enabled computer tablet with the SMART4MD app. Its core functionalities, intended to be used daily at home, are based on reminders, cognitive supporting activities, and sharing health information. Results: Inclusion of participants started in December 2017, and recruitment is expected to end in February 2019. Furthermore, there will be 3 follow-up visits at 6, 12, and 18 months after the baseline visit. Conclusions: This RCT is expected to offer benefits at several levels including in-depth knowledge of the possibilities of introducing a holistic multilayered information and communication technology solution for this group. SMART4MD has been developed in a process involving the structured participation of PwMCI, their informal carers, and clinicians. The adoption of SMART4MD faces the challenge of this age group's relative unfamiliarity with digital devices and services. However, this challenge can also be an opportunity for developing a digital device tailored to a group at risk of digital exclusion. This research responds to the wider call for the development of digital devices which are accessible and affordable to older people and this full scale RCT can hopefully serve as a model for further studies in this field.

    A Novel Instrument for Measuring Older People's Attitudes Toward Technology (TechPH): Development and Validation2019Ingår i: Journal of Medical Internet Research, ISSN 1438-8871, E-ISSN 1438-8871, Vol. 21, nr 5, artikel-id e13951Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The use of health technology by older people is coming increasingly in focus with the demographic changes. Health information technology is generally perceived as an important factor in enabling increased quality of life and reducing the cost of care for this group. Age-appropriate design and facilitation of technology adoption are important to ensure functionality and removal of various barriers to usage. Development of assessment tools and instruments for evaluating older persons' technology adoption and usage as well as measuring the effects of the interventions are of high priority. Both usability and acceptance of a specific technology or service are important factors in evaluating the impact of a health information technology intervention. Psychometric measures are seldom included in evaluations of health technology. However, basic attitudes and sentiments toward technology (eg, technophilia) could be argued to influence both the level of satisfaction with the technology itself as well as the perception of the health intervention outcome. Objective: The purpose of this study is to develop a reduced and refined instrument for measuring older people's attitudes and enthusiasm for technology based on relevant existing instruments for measuring technophilia A requirement of the new instrument is that it should be short and simple to make it usable for evaluation of health technology for older people. Methods: Initial items for the TechPH questionnaire were drawn from a content analysis of relevant existing technophilia measure instruments. An exploratory factor analysis was conducted in a random selection of persons aged 65 years or older (N=374) on eight initial items. The scale was reduced to six items, and the internal consistency and reliability of the scale were examined. Further validation was made by a confirmatory factor analysis (CFA). Results: The exploratory factor analysis resulted in two factors. These factors were analyzed and labeled techEnthusiasm and techAnxiety. They demonstrated relatively good internal consistency (Cronbach alpha=.72 and .68, respectively). The factors were confirmed in the CFA and showed good model fit (chi(2)(8)=21.2, chi(2)/df=2.65, comparative fit index=0.97, adjusted goodness-of-fit index=0.95, root mean square error of approximation=0.067, standardized root mean square residual=0.036). Conclusions: The construed TechPH score showed expected relations to external real-world criteria, and the two factors showed interesting internal relations. Different technophilia personality traits distinguish clusters with different behaviors of adaptation as well as usage of new technology. Whether there is an independent association with the TechPH score against outcomes in health technology projects needs to be shown in further studies. The instrument must also be validated in different contexts, such as other countries.

    A cross-sectional study of the associations between periodontitis and carotid arterial calcifications in an elderly population2016Ingår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 74, nr 2, s. 115-120Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective. To evaluate if the presence of periodontitis is associated with carotid arterial calcifications diagnosed on panoramic radiographs in an elderly population. Materials and methods. Study individuals were randomly selected from the Swedish civil registration database representing the aging population (60-96 years) in Karlskrona, Sweden. Bleeding on probing (BOP) and the deepest probing measurement at each tooth were registered. The proportions of teeth with a probing depth 5 mm and the proportion of teeth with bleeding on probing were calculated. Analog panoramic radiographs were taken and the proportion of sites with a distance 5 mm between the alveolar bone level and the cement-enamel junction (CEJ) were assessed. A diagnosis of periodontitis was declared if a distance between the alveolar bone level and the CEJ 5 mm could be identified from the panoramic radiographs at >10% of sites, probing depth of 5 mm at one tooth or more and with BOP at >20% of teeth. Results. Readable radiographs were obtained from 499 individuals. Carotid calcification was identified in 39.1%. Individuals were diagnosed with periodontitis in 18.4%. Data analysis demonstrated that individuals with periodontitis had a higher prevalence of carotid calcifications (Pearson (2) = 4.05 p < 0.05) and with a likelihood of 1.5 (95% CI = 1.0, 2.3, p < 0.05). Conclusions. Data analysis demonstrated a significant association between periodontitis and carotid calcification.

    Reinfection with Lyme borreliosis: A retrospective follow-up study in southern Sweden2002Ingår i: Scandinavian Journal of Infectious Diseases, ISSN 0036-5548, E-ISSN 1651-1980, s. 183-186Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    In a 5-y retrospective follow-up study in southern Sweden that initially included > 1000 individuals with previously diagnosed erythema migrans, factors that influenced the risk of reinfection with Lyme borreliosis were elucidated. The total frequency of reinfection was 4% and the number of tick bites influenced the risk of reinfection: those bitten > 10 times during the observation period had a 4-8-fold increased risk compared with those bitten < 5 times. Women manifested to a greater extent than men although both genders were bitten equally by ticks, thus indicating that women may be more susceptible to reinfection. All reinfected women were > 44 y old. The county of Kalmar including Oland was found to be highly endemic for reinfection with Lyme borreliosis. Thus the number of tick bites, gender, age and study area influenced the risk of reinfection.

    Clinical appearance of erythema migrans caused by Borrelia afzelii and Borrelia garinii: effect of the patient´s sex2006Ingår i: Wiener Klinische Wochenschrift, ISSN 0043-5325, E-ISSN 1613-7671, Vol. 118, nr 17-18, s. 531-537Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: The aim in this survey was to study the clinical characteristics of infections caused by Borrelia genospecies in patients with erythema migrans where Borrelial origin was confirmed by polymerase chain reaction. The aim was also to study factors influencing the clinical appearance of erythema migrans. Methods: The study was conducted in southern Sweden from May 2001 to December 2003 on patients 18 years and older attending with erythema migrans at outpatient clinics. All erythema migrans were verified by polymerase chain reaction, photographed and categorized into “annular” or “non-annular” lesions. A logistic regression model was used to analyze relations between the appearance of the erythema migrans (i.e., annular or non-annular) and factors that influenced its clinical appearances. Results: A total of 118 patients, 54 women (45.8%) and 64 men (54.2%), fulfilled the inclusion criteria. Of these patients, 74% were infected by B. afzelii, 26% by B. garinii ( p < 0.001). A total of 45% (38/85) of the erythema migrans were annular, 46% (39/85) were non-annular and 9.4% (8/85) were atypical. For men infected by B. afzelii the odds ratio of developing non-annular erythema migrans was 0.09 (95% CI: 0.03 - 0.33) in comparison with women with the same infection. Conclusions: In this prospective study of a large series of erythema migrans, where infecting genospecies were confirmed by polymerase chain reaction, the sex of patients infected with B. afzelii had a strong influence on the appearance of the rash. Patients infected by B. garinii more often had non-annular erythema migrans and a more virulent infection with more individuals presenting with fever, raised levels of C-reactive protein and seroreactivity in the convalescence sera.

    Clinical Aspects of Erythema Migrans in Southern Sweden2005Konferensbidrag (Refereegranskat)
    Abstract [en]

    Background: The aim of this study was to describe and categorize the different predominant patterns of PCR confirmed erythema migrans (EM) and to study possible correlations according to the clinical pictures and Borrelia substrains. Methods: Patients over 18 years old, seeking care with tick exposure and an EM were consecutively included during a study period of three years. We evaluated clinical and laboratory findings with regard to Borrelia burgdorferi s.l. spirochetes detected with nested Osp A PCR in skin biopsy specimens. Laboratory and serology testing were done acute, after 6 weeks and after 6 months. The patients were clinically evaluated at the initial visit and repeatedly after 14 days unitl recovery. Results: 118 patients (women=54, men=64) with a positive B. Burgdorferi s.l. PCR analysis were included. In this area totally 73.7% of the EM were caused by B. afzelii and 26.3% by B. garinii (p=0.0001). Leisons caused by B. garinii had a shorter duration from tick bite to the initial visit (p= 0.001) but there were no differences between the sizes of the EM, indicating a faster development of lesions caused by B. garinii. Patients with lesions caused by B. garinii to a greater extent had presented with fever at the initial visit (p=0.02). Also patients with B. garinii lesions to a greater extent had elevated levels of CRP at the initial visit (p=0.006). 45% of the EM were categorized as “annular”, 27% as “homogeneous”, 19% as “central erythemas” and 9% as “atypical”. The lesions caused by B. afzelii were predominately “annular” and the lesions caused by B. gaarinii were predominately “homogeneous”. Conclusions: In this study most EM were caused by B. afzelii. Leisons caused by B. garinii developed faster and the patients to a greater extent presented with fever and elevated levels of CRP at the initial visit. Leisons caused by B. garinii were mostly homogenous and by B. afzelii were mostly annular.

    Increased incidence of Lyme borreliosis in southern Sweden following mild winters and during warm, humid summers.2006Ingår i: European Journal of Clinical Microbiology and Infectious Diseases, ISSN 0934-9723, E-ISSN 1435-4373, Vol. 25, nr 7, s. 426-432Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim of the present study was to investigate the long-term incidence rate of Lyme borreliosis and, additionally, to determine whether a correlation exists between climatic factors and summer-season variations in the incidence of Lyme borreliosis. Climatic variability acts directly on tick population dynamics and indirectly on human exposure to Lyme borreliosis spirochetes. In this study, conducted in primary healthcare clinics in southeastern Sweden, electronic patient records from 1997-2003 were searched for those that fulfilled the criteria for erythema migrans. Using a multilevel Poisson regression model, the influence of various climatic factors on the summer-season variations in the incidence of erythema migrans were studied. The mean annual incidence rate was 464 cases of erythema migrans per 100,000 inhabitants. The incidence was significantly higher in women than in men, 505 and 423 cases per 100,000 inhabitants, respectively (p<0.001). The summer-season variations in the erythema migrans incidence rate correlated with the monthly mean summer temperatures (incidence rate ratio 1.12; p<0.001), the number of winter days with temperatures below 0 degrees C (incidence rate ratio 0.97; p<0.001), the monthly mean summer precipitation (incidence rate ratio 0.92; p<0.05), and the number of summer days with relative humidity above 86% (incidence rate ratio 1.04; p<0.05). In conclusion, Lyme borreliosis is highly endemic in southeastern Sweden. The climate in this area, which is favourable not only for human tick exposure but also for the abundance of host-seeking ticks, influences the summer-season variations in the incidence of Lyme borreliosis.

    Effect of Gender on Clinical and Epidemiologic Features of Lyme Borreliosis2007Ingår i: Vector Borne and Zoonotic Diseases, ISSN 1530-3667, E-ISSN 1557-7759, Vol. 7, nr 1, s. 34-41Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The aim is to highlight the influence of patients’ gender on Lyme borreliosis and especially erythema migrans (EM), focusing on exposure to tick bites, epidemiology, and the clinical picture. All studies were conducted in the county of Blekinge, located in southeastern Sweden. A prospective study was conducted in 235 individuals (women, n=110; men, n=125) engaged in recreational or occupational activities focusing on exposure to tick bites. A retrospective epidemiological study evaluating 123,495 electronic patients´ records (women, n=61,712; men, n=61,783) and a prospective clinical study including 118 patients (women, n=54; men, n=64) 18 years or older seeking care for EM > 5 cm in diameter with genospecies verified by polymerase chain reaction were conducted. Results: Women 40 years or older had a 48% higher risk than men 40 years or older and 42% higher risk than women younger than 40 years of attracting tick bites (0.0188 versus 0.0127 and 0.0188 versus 0.0132 tick bites respectively per hour). Additionally they had a 96% higher risk than men younger than 40 years of attracting tick bites (0.0188 versus 0.0096). The annual incidence rate of EM in women was 506 and in men 423 cases per 100,000 inhabitants (p<0.001). Significant differences in incidence rates occurred in those 40 years or older. Odds ratios for males infected with Borrelia afzelii developing nonannular EM were 0.09 (95% confidence interval [CI] 0.03 to 0.33) in comparison with females infected by Borrelia afzelii. Conclusions: Significant gender differences in the risk of contracting tick bites, incidence rates, and clinical picture of EM have been observed. Exposure to tick bites alone may not explain these observations and further studies need to be done to clarify the biologic, immunologic, and sociological mechanisms causing these differences.

    Association of diagnosis of ischaemic heart disease, diabetes mellitus and heart failure with cognitive function in the elderly population.2006Ingår i: European Journal of General Practice, ISSN 1381-4788, E-ISSN 1751-1402, Vol. 12, nr 3, s. 114-119Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    OBJECTIVE: The aim of this study was to describe the association between ischaemic heart disease (IHD), diabetes mellitus (DM) and heart failure (HF) and the prevalence of cognitive impairment. METHODS: In a cross-sectional, community-based study in Karlskrona, Sweden, 1402 participants of the Swedish National Study on Ageing and Care (60-96 y) underwent a medical examination and psychological testing including the Mini Mental State Examination (MMSE). Of these, 58% stated that they were treated for hypertension, IHD, DM or HF, or had ECG abnormalities (positive screen). RESULTS: The prevalence of cognitive impairment (MMSE score < 24) in patients treated for IHD, DM or HF was 28.5% compared to 16.1% in the population with a negative screen without cardiovascular disease or DM. After stratification by age, the difference was seen to be due to a higher prevalence of cognitive impairment in the age group 70-79 y, where 68.8% of the cognitively impaired came from the group treated for IHD, DM or HF. The odds ratio for cognitive impairment in this age group was 4.4 (95% CI 1.7-11.4), when compared to those with a negative screen as baseline. CONCLUSION: This study has shown that the patient group treated for IHD, DM or HF has a higher prevalence of cognitive impairment and a higher risk of developing early cognitive impairment between the ages of 70 and 79 y. Although this study has not provided conclusive evidence that cardiovascular disease and DM are associated with the early development of cognitive impairment, it provides incentive for further studies.

    Osteoporosis and peridontitis in older subjects participating in the Swedish National Survey on Aging and Care (SNAC-Blekinge)2011Ingår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 69, nr 4, s. 201-207Artikel, forskningsöversikt (Refereegranskat)
    Abstract [en]

    Abstract Objective. We assessed the relationships between (I) ultrasonography calcaneus T-scores (PIXI) and mandibular cortex characteristics on oral panoramic radiographs in older subjects; and (II) osteoporosis and periodontitis. Material and methods. We examined 778 subjects (53% women) aged 59-96 years. Periodontitis was defined by alveolar bone loss assessed from panoramic radiographs. Results. PIXI calcaneus T-values ≤-2.5 (osteoporosis) were found in 16.3% of women and in 8.1% of men. PIXI calcaneus T-values <-1.6 (osteoporosis, adjusted) were found in 34.2% of women and in 21.4% of men. The age of the subjects and PIXI T-values were significantly correlated in women (Pearson's r = 0.37, P < 0.001) and men (Pearson's r = 0.19, P < 0.001). Periodontitis was found in 18.7% of subjects defined by alveolar bone level ≥5 mm. Subjects with osteoporosis defined by adjusted PIXI T-values had fewer remaining teeth [mean difference 4.1, 95% confidence interval (CI) -1.1 to -6.5, P < 0.001]. The crude odds ratio (OR) of an association between the panoramic assessment of mandibular cortex erosions as a sign of osteoporosis and the adjusted T-value (T-value cut-off <-1.6) was 4.8 (95% CI 3.1-7.2, P < 0.001; Pearson χ(2) = 60.1, P < 0.001). A significant OR between osteoporosis and periodontitis was only found in women for the T-value cut-off ≤-2.5 (crude OR 1.8, 95% CI 1.1-3.3, P < 0.03). Conclusions. An association between osteoporosis and periodontitis was only confirmed in women. The likelihood that the mandibular cortex index agrees with adjusted PIXI T-values is significant.

    5-y follow-up study of patients with neuroborreliosis2002Ingår i: Scandinavian Journal of Infectious Diseases, ISSN 0036-5548, E-ISSN 1651-1980, Vol. 34, nr 6, s. 421-425Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The objective of this follow-up study was to determine the long-term outcome of strictly classified cases of neuroborreliosis treated with antibiotics. A one-year prospective population-based survey of Lyme borreliosis was conducted in southern Sweden, between 1992 and 1993. A total of 349 identified cases with suspected neuroborreliosis were followed up 5 years later. Medical records were reviewed and all participants filled in a questionnaire. Of those classified with definite neuroborreliosis 114/130 completed the follow-up, of whom 111 had completed the initial antibiotic treatment. Of the 114 patients followed up, 86 (75%) had recovered completely and 70 (61%) had recovered within 6 months. Residual neurological symptoms such as facial palsy, concentration disorder, paresthesia and/or neuropathy were reported by 28/114. No significant differences between different antibiotic treatments were observed in terms of occurrence of sequelae. To conclude, we found that 25% (95% confidence interval 17-33%) of the patients suffered from residual neurological symptoms 5 years post-treatment. However, the clinical outcome of treated neuroborreliosis is favourable as only 14/114 (12%) of the patients had sequelae that influenced their daily activity post-treatment. Early diagnosis and treatment would seem to be of great importance in order to avoid such sequelae.

    A 5-years follow-up of patients with neuroborreliosis.2002Konferensbidrag (Refereegranskat)
    Abstract [en]

    The objective of this follow-up study was to determine the long-term outcome in patients treated with antibiotics for strictly classified cases of neuroborreliosis. A one-year prospective population-based survey of Lyme borreliosis was conducted in southern Sweden, 1992-1993. Totally 349 identified cases with suspected neuroborreliosis were registered. Of those, 130 were classified as definitively neuroborreliosis and followed up five years later. Medical records were reviewed and all participants filled in a questionnaire. Totally, 114/130 (88%) completed the follow-up of whom 111/114 (97%) had fulfilled the initial antibiotic treatment. Of these, 86/114 (75%) had recovered completely and 70 (61%) recovered within six months. However 28/114 (25%) suffered from remaining neurological symptoms such as facial palsy, concentration disorder, paresthesia and/or neuropathy. The longer the duration from the neurological symptoms onset to antibiotic treatment the higher was the rate of sequelae. Of those who were treated within 30 days 5/32 (16%) and of those who were treated after 30 days 16/41 (39%) respectively, reported sequelae. Women suffered significantly more from sequelae compared to men, this difference was not seen among the children. No significant differences between the different antibiotic treatments given and experience of sequelae were seen. To conclude, we found that 25% (95% CI 17% to 33%) of the patients suffered from remaining neurological symptoms five years post treatment. However, the clinical outcome of treated neuroborreliosis is favourable as only 14/114 (12%) of the patients had sequelae that influenced their daily activity post treatment and early diagnosis and treatment seems to be of great importance to possibly avoid also these cases.

    Safety, immunogenicity and antibody persistence following an investigational Streptococcus pneumoniae and Haemophilus influenzae tri-protein vaccine: a phase 1 randomized controlled study in healthy adults.2014Ingår i: Clinical and Vaccine Immunology, ISSN 1556-6811, E-ISSN 1556-679X, Vol. 21, nr 1, s. 56-65Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    We investigated a protein-based nontypeable Haemophilus influenzae (NTHi) and pneumococcal (HiP) vaccine containing pneumococcal histidine triad D (PhtD), detoxified pneumolysin (dPly), and NTHi protein D (PD) in adults. In a phase I study, 40 healthy 18- to 40-year-old subjects were randomized (2:2:1) to receive two HiP doses administered 60 days apart, with or without AS03 adjuvant (HiP-AS and HiP groups, respectively), or Engerix B (GlaxoSmithKline, Belgium) as a control. Safety, antibodies, and antigen-specific CD4+ T-cell immune responses were assessed before and until 480 days after vaccination. No serious adverse events were reported, and no subject withdrew due to an adverse event. Local and systemic symptoms were reported more frequently in the HiP-AS group than in the other two groups. The frequency and intensity of local and systemic symptoms appeared to increase after the second dose of HiP-AS or HiP but not Engerix B. Antibody geometric mean concentrations (GMCs) for PhtD, dPly, and PD increased after each dose of HiP-AS or HiP, with higher GMCs being observed in the HiP-AS group (statistically significant for anti-PD after dose 1 and anti-Ply after dose 2). GMCs remained higher at day 420 than prior to vaccination in both the HiP-AS and HiP groups. Antigen-specific CD4+ T cells increased after each dose but were unmeasurable by day 480. Two doses of an investigational PhtD-dPly-PD protein vaccine induced humoral immunity and antigen-specific CD4+ T-cell responses after each dose, with generally higher responses when the vaccine was administered with AS03. HiP combined with AS03 appeared to be more reactogenic than the antigens alone. (This study has been registered at ClinicalTrials.gov under registration no. NCT00814489.)

    Case Management for Frail Older Adults Through Tablet Computers and Skype2016Ingår i: Informatics for Health and Social Care, ISSN 1753-8157, E-ISSN 1753-8165, Vol. 41, nr 4, s. 405-416Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: Frail older adults are high consumers of medical care due to their age and multiple chronic conditions. Regular contact with a case manager has been proven to increase well-being of frail older adults and reduce their number of health-care visits. Skype calls through tablet PCs can offer easier communication. Objective: This paper examines frail older adults’ use of tablet computers and Skype, with their case managers.Method: Interviews were conducted on 15 frail older adults. A content analysis was used to structure and analyze the data. Results: The results indicate that tablet computers were experienced in a positive way for most frail older adults. Conflicting feelings did emerge, however, as to whether the frail elderly would adopt this in the long run. Skype needs to be tested further as to whether this is a good solution for communication with their case managers. Strong technical support and well-functioning technology are important elements to facilitate use. Conclusion: Using Skype and tablet PCs do have potential for frail older adults, but need to be tested further. © 2015 Taylor & Francis

    Maintaining cognitive function with internet use: A two-country, six-year longitudinal study2019Ingår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 31, nr 7, s. 929-936Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objectives: Maintaining good cognitive function with aging may be aided by technology such as computers, tablets, and their applications. Little research so far has investigated whether internet use helps to maintain cognitive function over time.Design: Two population-based studies with a longitudinal design from 2001/2003 (T1) to 2007/2010 (T2).Setting: Sweden and the Netherlands.Participants: Older adults aged 66 years and above from the Swedish National Study on Ageing and Care (N = 2,564) and from the Longitudinal Aging Study Amsterdam (N = 683).Measurements: Internet use was self-reported. Using the scores from the Mini-Mental State Examination (MMSE) from T1 and T2, both a difference score and a significant change index was calculated. Linear and logistic regression analysis were performed with difference score and significant change index, respectively, as the dependent variable and internet use as the independent variable, and adjusted for sex, education, age, living situation, and functional limitations. Using a meta-analytic approach, summary coefficients were calculated across both studies.Results: Internet use at baseline was 26.4% in Sweden and 13.3% in the Netherlands. Significant cognitive decline over six years amounted to 9.2% in Sweden and 17.0% in the Netherlands. Considering the difference score, the summary linear regression coefficient for internet use was-0.32 (95% CI:-0.62,-0.02). Considering the significant change index, the summary odds ratio for internet use was 0.54 (95% CI: 0.37, 0.78).Conclusions: The results suggest that internet use might play a role in maintaining cognitive functioning. Further research into the specific activities that older adults are doing on the internet may shine light on this issue. © 2019 International Psychogeriatric Association.

    Factors influencing Internet usage in older adults (65 years and above) living in rural and urban Sweden2015Ingår i: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 21, nr 3, s. 237-249Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Older adults living in rural and urban areas have shown to distinguish themselves in technology adoption; a clearer profile of their Internet use is important in order to provide better technological and health-care solutions. Older adults' Internet use was investigated across large to midsize cities and rural Sweden. The sample consisted of 7181 older adults ranging from 59 to 100 years old. Internet use was investigated with age, education, gender, household economy, cognition, living alone/or with someone and rural/urban living. Logistic regression was used. Those living in rural areas used the Internet less than their urban counterparts. Being younger and higher educated influenced Internet use; for older urban adults, these factors as well as living with someone and having good cognitive functioning were influential. Solutions are needed to avoid the exclusion of some older adults by a society that is today being shaped by the Internet.

    Factors associated with change in Internet usage of Swedish older adults (2004-2010)2013Ingår i: Health Informatics Journal, ISSN 1460-4582, E-ISSN 1741-2811, Vol. 19, nr 2, s. 152-162Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The increased reliance on Internet use in social functions has presumably left out a part of the population: the oldest-older adults. These are people who have not kept themselves up to date with the technological developments for various reasons. There are, however, exceptions from whom we have something to learn. This study investigates the older people in Sweden who started to use the Internet over a period of 6 years. Cognition, extraversion, openness, functional disability, household economy, sex, age and education were investigated in relation to starting to use the Internet. A chi-square test, Spearman correlation and a logistic regression analysis were conducted. It was found that higher cognition, being male and being between the ages of 60 and 80 years were determining factors in starting to use the Internet for the Swedish older adult. Our results indicate that the oldest-older adults are slow to adapt to using the Internet and more attention should be paid on how to support this group.

    Sequence typing reveals extensive strain diversity of the Lyme borreliosis agents Borrelia burgdorferi in North America and Borrelia afzelii in Europe.2004Ingår i: Microbiology, ISSN 1350-0872, E-ISSN 1465-2080, Vol. 150, nr 6, s. 1741-1755Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The genetic polymorphism of Borrelia burgdorferi and Borrelia afzelii, two species that cause Lyme borreliosis, was estimated by sequence typing of four loci: the rrs-rrlA intergenic spacer (IGS) and the outer-membrane-protein gene p66 on the chromosome, and the outer-membrane-protein genes ospA and ospC on plasmids. The major sources of DNA for PCR amplification and sequencing were samples of the B. burgdorferi tick vector Ixodes scapularis, collected at a field site in an endemic region of the north-eastern United States, and the B. afzelii vector Ixodes ricinus, collected at a similar site in southern Sweden. The sequences were compared with those of reference strains and skin biopsy isolates, as well as database sequences. For B. burgdorferi, 10-13 alleles for each of the 4 loci, and a total of 9 distinct clonal lineages with linkage of all 4 loci, were found. For B. afzelii, 2 loci, ospC and IGS, were examined, and 11 IGS genotypes, 12 ospC alleles, and a total of 9 linkage groups were identified. The genetic variants of B. burgdorferi and B. afzelii among samples from the field sites accounted for the greater part of the genetic diversity previously reported from larger areas of the north-eastern United States and central and northern Europe. Although ospC alleles of both species had higher nucleotide diversity than other loci, the ospC locus showed evidence of intragenic recombination and was unsuitable for phylogenetic inference. In contrast, there was no detectable recombination at the IGS locus of B. burgdorferi. Moreover, beyond the signature nucleotides that specified 10 IGS genotypes, there were additional nucleotide polymorphisms that defined a total of 24 subtypes. Maximum-likelihood and parsimony cladograms of B. burgdorferi aligned IGS sequences revealed the subtype sequences to be terminal branches of clades, and the existence of at least three monophyletic lineages within B. burgdorferi. It is concluded that B. burgdorferi and B. afzelii have greater genetic diversity than had previously been estimated, and that the IGS locus alone is sufficient for strain typing and phylogenetic studies.

    Abstract [en]

    Partial sequencing of the 16S-23S rDNA intergenic spacer showed two to four genotypes each for Borrelia hermsii and B. turicatae, both relapsing fever agents transmitted by argasid ticks, and for B. miyamotoi and B. lonestari, transmitted by ixodid ticks. Field surveys of Ixodes ticks in Connecticut and Sweden showed limited local diversity for B. miyamotoi.

    Abstract [en]

    Aim: This study aimed to identify factors affecting health-related quality of life (HRQoL) of older adults with cognitive impairment and to describe the association of these factors with different components of HRQoL. Design: A cross-sectional, descriptive research design was used. Methods: Data were collected from 247 individuals aged 60 years and older from a Swedish longitudinal cohort study. The Short-Form Health Survey-12 (SF-12) and EuroQol (EQ-5D) were used to assess HRQoL. The data were analysed using descriptive and comparative statistics. Results: The present study identified several factors that influenced HRQoL of older adults with cognitive impairment. The results of a multiple logistic regression analysis revealed that the following factors were associated with physical and mental HRQoL: dependency in activities of daily living (ADL), receiving informal care and feelings of loneliness and pain. © 2019 The Authors.

    Designing with Priorities and Thresholds for Health Care Heterogeneity: The Approach of Constructing Parametric Ontology2015Konferensbidrag (Refereegranskat)
    Abstract [en]

    Designing systems working in health care needs complying with the heterogeneous, overlapping, non-overlapping, competing, or even contradicting requirements expressed by the various actors of the health care complex environment, including regulatory bodies. The unification method introduced in this paper, utilized ontological struc- tures to unify heterogeneous requirements in different levels of ab- straction. Also the weighting and threshold algorithms defined upon the ontology structure allows to both prioritize the requirements and align design resources upon that priority, at the same time to enforce regulatory requirements in an easy, clear and integrated way and reject designs which cannot comply with them. Application of the method introduced in this paper is not limited to health care, but it might be applied in design for any heterogeneous environment.

    Evaluating Health Information Systems Using Ontologies2016Ingår i: JMIR Medical Informatics, ISSN 2291-9694, Vol. 4, nr 2, artikel-id e20Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: There are several frameworks that attempt to address the challenges of evaluation of health information systems by offering models, methods, and guidelines about what to evaluate, how to evaluate, and how to report the evaluation results. Model-based evaluation frameworks usually suggest universally applicable evaluation aspects but do not consider case-specific aspects. On the other hand, evaluation frameworks that are case specific, by eliciting user requirements, limit their output to the evaluation aspects suggested by the users in the early phases of system development. In addition, these case-specific approaches extract different sets of evaluation aspects from each case, making it challenging to collectively compare, unify, or aggregate the evaluation of a set of heterogeneous health information systems.

    Objectives: The aim of this paper is to find a method capable of suggesting evaluation aspects for a set of one or more health information systems—whether similar or heterogeneous—by organizing, unifying, and aggregating the quality attributes extracted from those systems and from an external evaluation framework.

    Methods: On the basis of the available literature in semantic networks and ontologies, a method (called Unified eValuation using Ontology; UVON) was developed that can organize, unify, and aggregate the quality attributes of several health information systems into a tree-style ontology structure. The method was extended to integrate its generated ontology with the evaluation aspects suggested by model-based evaluation frameworks. An approach was developed to extract evaluation aspects from the ontology that also considers evaluation case practicalities such as the maximum number of evaluation aspects to be measured or their required degree of specificity. The method was applied and tested in Future Internet Social and Technological Alignment Research (FI-STAR), a project of 7 cloud-based eHealth applications that were developed and deployed across European Union countries.

    Results: The relevance of the evaluation aspects created by the UVON method for the FI-STAR project was validated by the corresponding stakeholders of each case. These evaluation aspects were extracted from a UVON-generated ontology structure that reflects both the internally declared required quality attributes in the 7 eHealth applications of the FI-STAR project and the evaluation aspects recommended by the Model for ASsessment of Telemedicine applications (MAST) evaluation framework. The extracted evaluation aspects were used to create questionnaires (for the corresponding patients and health professionals) to evaluate each individual case and the whole of the FI-STAR project.

    Conclusions: The UVON method can provide a relevant set of evaluation aspects for a heterogeneous set of health information systems by organizing, unifying, and aggregating the quality attributes through ontological structures. Those quality attributes can be either suggested by evaluation models or elicited from the stakeholders of those systems in the form of system requirements. The method continues to be systematic, context sensitive, and relevant across a heterogeneous set of health information systems.

    Most Influential Qualities in Creating Satisfaction Among the Users of Health Information Systems: A Study in Seven EU Countries2018Ingår i: JMIR Medical Informatics, Vol. 6, nr 4, s. 3-21Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background:

    Several models suggest how the qualities of a product or service influence user satisfaction. Models, such as the Customer Satisfaction Index (CSI), Technology Acceptance Model (TAM), and Delone and McLean Information Systems Success (D&M IS), demonstrate those relations and have been used in the context of health information systems.

    Objective:

    We want to investigate which qualities foster greater satisfaction among patient and professional users. In addition, we are interested in knowing to what extent improvement in those qualities can explain user satisfaction and if this makes user satisfaction a proxy indicator of those qualities.

    Methods:

    The Unified eValuation using ONtology (UVON) method was utilised to construct an ontology of the required qualities for seven e-health applications being developed in the FI-STAR project, a European Union (EU) project in e-health. The e-health applications were deployed across seven EU countries. The ontology included and unified the required qualities of those systems together with the aspects suggested by the Model for ASsessment of Telemedicine applications (MAST) evaluation framework. Two similar questionnaires, for 87 patient users and 31 health professional users, were elicited from the ontology. In the questionnaires, user was asked if the system has improved the specified qualities and if the user was satisfied with the system. The results were analysed using Kendall correlation coefficients matrices, incorporating the quality and satisfaction aspects. For the next step, two Partial Least Squares Structural Equation Modelling (PLS-SEM) path models were developed using the quality and satisfaction measure variables and the latent construct variables that were suggested by the UVON method.

    Results:

    Most of the quality aspects grouped by the UVON method are highly correlated. Strong correlations in each group suggest that the grouped qualities can be measures which reflect a latent quality construct. The PLS-SEM path analysis for the patients reveals that the effectiveness, safety, and efficiency of treatment provided by the system are the most influential qualities in achieving and predicting user satisfaction. For the professional users, effectiveness and affordability are the most influential. The parameters of the PLS-SEM that are calculated allow for the measurement of a user satisfaction index similar to CSI for similar health information systems.

    Conclusions:

    For both patients and professionals, the effectiveness of systems highly contributes to their satisfaction. Patients care about improvements in safety and efficiency, while professionals care about improvements in the affordability of treatments with health information systems. User satisfaction is reflected more in the users' evaluation of system output and fulfilment of expectations, but slightly less in how far the system is from ideal. Investigating satisfaction scores can be a simple, fast way to infer if the system has improved the abovementioned qualities in treatment and care.

    Designing a model app for older persons with cognitive impairment: insights from a usability perspective2018Ingår i: Gerontechnology, ISSN 1569-1101, E-ISSN 1569-111X, Vol. 17, s. 80-Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose Research indicates that health-oriented applications on mobile units such as smartphones and PDAs, so called mHealth applications, can be useful to support older persons with cognitive impairment and their informal caregivers1. However, several studies suggest that a prerequisite for older persons to start using computer-based technology is that it offers individual customization according to personal preference 2,3,4. In the ongoing Horizon 2020 project SMART4MD (Support, Monitoring And Reminder Technology for older persons with Mild Dementia), an health-oriented model app has been developed through a user-centered process involving stakeholders in six European countries and with an emphasis on customization to allow for the various needs of older persons with cognitive impairment and their informal caregivers. The aim of this study is to gain insights about the specific needs of the target group and success factors related to the user-centered design process. Method Within the frames of the SMART4MD project, an initial Feasibility study was conducted in two countries (Spain and Sweden) simultaneously, in which in total nineteen persons with cognitive impairment aged 66-93, and their respective informal caregivers, performed a taskbased usability test of the SMART4MD model app individually in a clinical setting, followed by a four-week testing of the app in their home environment. Finally, a usability evaluation was done through individual structured interviews. Results & Discussion The result indicates that less exposure to similar technology affects both ability and self-esteem when confronted with the model app, and that evaluating usability with the target group using standard forms within usability testing requires pre-cautions. © 2018 International Society for Gerontechnology.

    The Cost Effectiveness of M-health Interventions for Older Adults: Protocol for a Systematic Review2018Manuskript (preprint) (Övrigt vetenskapligt)
    Abstract [en]

    Background: Many studies reported effectiveness of mhealth interventions targeting middle aged and older adults to improve healthcare delivery process, efficacy and management of chronic diseases. However, the knowledge about their cost-effectiveness is important to implement mhealth interventions at large scale for proper allocation of scarce resources. This systematic review will summarize the results from identified studies for the cost effectiveness of mhealth interventions aimed for middle aged and older adults.

    Method: mhealth interventions aimed to improve healthcare delivery process, efficacy and delivering training will be included in this systematic review. A comprehensive electronic search strategy will be used to identify health economic evaluations, published since 2007, and indexed in Pubmed, Scopus and CINAHL. The search strategy will include terms (and synonyms) for the following mhealth devices: mobile phone, smartphone, mhealth. Middle aged and older adults will be used to identify all mhealth interventions introduced to middle aged and older adults. Terms such as economic evaluation, cost effectiveness, cost utility etc will be used to identify economic evaluations of all mhealth interventions.

    Discussion: This systematic review will report evidence on cost effectiveness of mhealth interventions targeting middle aged and older adults.

    Abstract [en]

    OBJECTIVE: The objective was to study primary healthcare patients' understanding of their diagnosis of heart failure (HF), using patients treated for diabetes mellitus (DM) as a comparative group. DESIGN: A cross-sectional community based study. SETTING: Karlskrona community situated on the Swedish south-east coast with 60,600 inhabitants. SUBJECTS: A total of 1402 subjects, aged 60-96 years in 10 age cohorts, selected randomly from the national population registry participating in the Swedish National study on Ageing and Care - Blekinge. MAIN OUTCOME MEASURES: Understanding of diagnosis of HF or DM in primary healthcare. Prevalence of cognitive impairment. RESULTS: In all, 39.8% of patients with a diagnosis of HF treated in primary healthcare and 97.1% of patients with DM had an understanding of their respective diagnosis. Cognitive impairment was significantly more prevalent in the groups of patients treated for HF (OR 1.9, 95% CI 1.2 to 3.0) and DM (OR 1.8, 95% CI 1.1 to 3.1), when compared with those not treated for either HF or DM. The odds ratio for understanding of diagnosis was 0.013 (95% CI 0.003 to 0.052, p < 0.001) in patients treated for HF, compared with patients treated for DM, when adjusted for the subject's age, sex, and cognitive function. CONCLUSION: In this study it was shown that patients' understanding of their diagnosis was highly dependent on diagnosis, independently of age, sex, or cognitive function. The results suggest that there is room for improvement of care in primary healthcare, to increase HF patients' understanding of their diagnosis.

    Diagnosis and treatment of heart failure in primary health care among elderly patients with non-insulin-dependent diabetes mellitus, with special reference to use of echocardiography2003Ingår i: Scandinavian Journal of Primary Health Care, ISSN 0281-3432, E-ISSN 1502-7724, Vol. 21, nr 2, s. 96-98Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective-The aim of the present study was to describe how the diagnosis of heart failure (HF) was assessed, aetiology and management in elderly patients with non-insulin-dependent diabetes mellitus (NIDDM) in primary health care, with special reference to use of echocardiography. Design-Descriptive retrospective investigation. Setting-Ronneby and Karlskrona communities, both situated on the Swedish south-east coast, 28,600 and 60,600 inhabitants, respectively. Patients-279 patients with NIDDM, mean age 77 years (range 70-85). Main outcome measures-Prevalence, aetiology, diagnostic procedures and management of HF. Results-The majority of patients were given the diagnosis of HF mainly as a result of clinical examination, ECG and chest X-ray, or of hospitalisation for HF. The diagnosis of HF by the primary care physicians was based on an objective evaluation of cardiac function in 8% of the patients. Hypertension was the predominant associated disease, followed by ischaemic heart disease (IHD). Therapy included diuretics (91%), angiotensin-converting enzyme (ACE) inhibitors (43%) and digoxin (53%). Conclusion-There is still a gap between current management of HF in primary care and guidelines, particularly in the case of diagnosis that is not generally based on an objective evaluation of cardiac function.

    Comparison between the Klemetti index and heel DXA BMD measurements in the diagnosis of reduced skeletal bone mineral density in the elderly.2005Ingår i: Osteoporosis International, ISSN 0937-941X, E-ISSN 1433-2965, Vol. 16, nr 8, s. 999-1003Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Osteopenia/osteoporosis affect many elderly people and might not be detected until symptoms of fractures occur. Early detection of osteopenia/osteoporosis is important and would allow preventive measures and treatment. Access to screening for osteopenia/osteoporosis is often limited, whereas panoramic radiography is commonly used in dentistry. The aim of this study was to determine the validity of the Klemetti index (KI), measured on panoramic radiographs, in the diagnosis of osteopenia/osteoporosis as defined by a bone mineral density (BMD) measurement below -1.5 standard deviations (SDs) of a community based sample. In total, 211 consecutive participants (102 men and 109 women) 60-96 years in the SNAC-Blekinge study (Swedish National Study on Ageing and Care) underwent bone densitometry [by dual-energy X-ray absorptiometry (DXA)] of both heels. A panoramic radiograph was taken of each participant, and mandibular cortex on a panoramic radiograph was classified as '0' or normal (even and sharp endosteal margin), '1', moderately eroded (evidence of lacunar resorption or endosteal cortical residues), or '2', severely eroded (unequivocal porosity). From logistic regression, the odds ratio of having a BMD measurement below -1.5 SD was 8.04 (95% CI 2.39 to 27.12, P<0.001) in the 'osteopenic' (KI category 2), compared with the 'normal' group (KI categories 0 and 1). Receiver operating characteristic (ROC) curve analysis was used to measure the validity of the KI indicating osteopenia (KI category 2) in predicting reduced BMD. This point provided a sensitivity of 50% and a specificity of 89%. Positive and negative predictive values were 21% and 97%, respectively. There were 87% correctly classified subjects. The area under the ROC curve was 0.64. The present study demonstrated that a negative finding (KI category <2) is highly predictive of the absence of osteopenia/osteoporosis as defined by the DXA measurements.

    Pedal dermatophyte infection in psoriasis.2004Ingår i: British Journal of Dermatology, ISSN 0007-0963, Vol. 50(6), s. 1125-1118Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND: Dermatophyte infections have been considered rare in psoriasis. However, there are data indicating that tinea unguium is as common or even more common in psoriasis compared with healthy controls. Tinea unguium is generally a secondary event to tinea pedis infection. OBJECTIVES: To study the prevalence of tinea pedis and tinea unguium in psoriasis compared with a control group. METHODS: Consecutive psoriasis outpatients aged 18-64 years attending a department of dermatology were examined. Samples for direct microscopy and culture were taken from the interdigital spaces, soles and toenails. Consecutive patients without signs of psoriasis or atopic dermatitis seeking examination of moles constituted the control group. RESULTS: In total, 239 patients with psoriasis and 245 control patients were studied. The prevalence of tinea pedis was 8.8%[95% confidence interval (CI) +/- 3.6%] in the psoriasis group and 7.8% (95% CI +/- 3.4%) in the control group. The corresponding figures for prevalence of tinea unguium were 4.6% (95% CI +/- 2.7%) and 2.4% (95% CI +/- 1.9%), respectively. The differences found in the psoriasis vs. the control groups were not statistically significant. CONCLUSIONS: This study does not support the hypothesis that the prevalence of tinea pedis and tinea unguium in patients with psoriasis differs from that in a normal population.

    Lyme borreliosis reinfection: might it be explained by a gender difference in immune response?2006Ingår i: Immunology, ISSN 0019-2805, E-ISSN 1365-2567, Vol. 118, nr 2, s. 224-232Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Lyme borreliosis is a tick-borne disease often manifesting as a circular skin lesion. This cutaneous form of the disease is known as erythema migrans. In a 5-year follow-up study in southern Sweden, 31 of 708 individuals initially diagnosed with erythema migrans and treated with antibiotics were found to be reinfected with Borrelia burgdorferi. Although men and women were tick-bitten to the same extent, 27 of the 31 reinfected individuals were women, all of whom were over 44 years of age. The aim of this study was to determine whether this discrepancy in gender distribution could be a result of differences in immunological response. Twenty single-infected and 21 reinfected women and 18 single-infected and three reinfected men were included in the study. None of the participants showed any sign of an ongoing B. burgdorferi infection, and thus the habitual response was captured. Lymphocytes were separated from blood and stimulated with antigens. The secretion of interleukin (IL)-4, IL-6, IL-10, interferon (IFN)-gamma and tumour necrosis factor (TNF)-alpha was measured by enzyme-linked immunosorbent assay (ELISA), enzyme-linked immunosorbent spot-forming cell assay (ELISPOT) or Immulite. No difference was detected in cytokine secretion between single-infected and reinfected individuals. We also compared the immunological response in men and women, regardless of the number of B. burgdorferi infections. Women displayed a significantly higher spontaneous secretion of all cytokines measured. The ratios of IL-4:IFN-gamma and IL-10:TNF-alpha were significantly higher in women. Gender differences in immune reactivity might in part explain the higher incidence of reinfection in women. The higher IL-4:IFN-gamma and IL-10:TNF-alpha ratios seen in women indicate that postmenopausal women have T helper type 2 (Th2)-directed reactivity with impaired inflammatory responses which might inhibit the elimination of spirochetes.

    Horizontal and vertical targeting: a population-based comparison of public eldercare services in urban and rural areas of Sweden2016Ingår i: Aging Clinical and Experimental Research, ISSN 1594-0667, E-ISSN 1720-8319, Vol. 28, nr 1, s. 147-158Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The concepts of target efficiency can be used to assess the extent to which service provision is in line with the needs of the population. Horizontal target efficiency denotes the extent to which those deemed to need a service receive it and vertical target efficiency is the corresponding extent to which those who receive services actually need them. The aim of this study was to assess the target efficiency of the Swedish eldercare system and to establish whether target efficiencies differ in different geographical areas such as large urban, midsize urban and rural areas. Vertical efficiency was measured by studying those people who received eldercare services and was expressed as a percentage of those who received services who were functionally dependent. To measure horizontal target efficiency, data collected at baseline in the longitudinal population study SNAC (Swedish National study on Aging and Care) during the years 2001-2004 were used. The horizontal efficiency was calculated as the percentage of functionally dependent persons who received services. Functional dependency was measured as having difficulty with instrumental activities of daily living (IADL) and/or personal activities of daily living (PADL). Services included long-term municipal eldercare services (LTC). Horizontal target efficiency for the public LTC system was reasonably high in all three geographical areas, when using dependency in PADL as the measure of need (70-90 %), but efficiency was lower when the less restrictive measure of IADL dependency was used (40-50 %). In both cases, the target efficiency was markedly higher in the large urban and the rural areas than in the midsize urban areas. Vertical target efficiency showed the same pattern-it was almost 100 % in all areas for IADL dependency, but only 50-60 % for PADL dependency. Household composition differed in the areas studied as did the way public long-term care was provided to people living alone as compared to those co-habiting.

    A longitudinal study integrating population, care and social services data. The Swedish National study on Aging and Care (SNAC).2004Ingår i: Aging Clinical and Experimental Research, ISSN 1594-0667, E-ISSN 1720-8319, Vol. 16, nr 2, s. 158-168Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    BACKGROUND AND AIMS: A large, national, long-term, longitudinal, multi-purpose study has been launched in Sweden--the Swedish National study on Aging and Care (SNAC). The study involves four research centers collecting data in four different areas of Sweden. METHODS: The study consists of two parts: the population part and the care and services part. In the population part, a large, representative panel of elders in different age cohorts is followed over time to record and describe the aging process from different aspects. In the care and services part, a systematic, longitudinal, individually-based collection of data is performed concerning provision of care and services together with functional ability, specific health care problems, and living conditions of the recipients living in the area. RESULTS: The data collection in the population part of the SNAC is not yet completed. In the present article, some preliminary results are reported from the care and services part. These pertain to comparisons between the participating areas with respect to the prevalence of disability among those receiving care and social services in their ordinary homes and those receiving care in special accommodation. A comparison is also presented with regard to the amount of home help provided to subjects with a given disability. CONCLUSIONS: This project has several advantages. It is expected to generate a rich data base relevant for future research on aging and care and to have a direct impact on the future Swedish system of care and services for the elderly.

    Horizontal and vertical target efficiency – a comparison between users and non-users of public long-term care in Sweden2014Ingår i: Ageing & Society, ISSN 0144-686X, E-ISSN 1469-1779, Vol. 34, nr 4, s. 700-719Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    The extent to which a system of services is in tune with the needs of the population can be expressed in terms of target efficiency, which includes horizontal target efficiency – the extent to which those deemed to need a service receive it – and vertical target efficiency – the corresponding extent to which those who receive a service actually need it. Vertical efficiency can be measured by looking only at those receiving services. To measure horizontal target efficiency in a population, one must have access to population surveys. Data were taken from the baseline survey of the Swedish National Study on Ageing and Care (SNAC study). The results show that more than 80 per cent of those dependent in personal activities of daily living in the studied geographic areas were users of public long-term care (LTC). Dependency in instrumental activities of daily living was identified as the most important predictor of using LTC. Vertical target efficiency was 83–95 per cent depending on age, gender and type of household, if need was defined as dependency in instrumental activities of daily living. It was considerably lower, 35–61 per cent when defined as dependency in personal daily activities. Overall, long-term target efficiency in Sweden must be regarded as high. Few persons who need public LTC services fail to receive them.

    Negative psychosocial and heavy physical workloads associated with musculoskeletal pain interfering with normal life in older adults: Cross-sectional analysis2015Ingår i: Scandinavian Journal of Public Health, ISSN 1403-4948, E-ISSN 1651-1905, Vol. 43, nr 5, s. 453-459Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aims: Pain is one of the most frequent reasons for seeking health care, and is thus a public health problem. Although there is a progressive increase in pain and impaired physical function with age, few studies are performed on older adults. The aim of this study was to investigate if there are associations between musculoskeletal pain interfering with normal life in older adults and physical and psychosocial workloads through life. Methods: The association of heavy physical workload and negative psychosocial workload and musculoskeletal pain interfering with normal life (SF 12) was analyzed by multiple logistic regression. The model was adjusted for eight background covariates: age, gender, growing-up environment, educational level, if living alone or not, obesity, smoking, and leisure physical activity. Results: Negative psychosocial and heavy physical workloads were independently associated with musculoskeletal pain interfering with normal life (adjusted OR: 4.44, 95% CI: 2.84-6.92), and (adjusted OR: 1.88, 95% CI: 1.20-2.93), respectively. The background covariates female gender and higher education were also associated with musculoskeletal pain interfering with normal life, and physical leisure activity was inversely associated. Conclusions: The findings suggest that negative psychosocial and heavy physical workloads are strongly associated with musculoskeletal pain interfering with normal life in older adults.

    The importance of weak physical performance in older adults for the development of musculoskeletal pain that interferes with normal life: A prospective cohort study2019Ingår i: Scandinavian Journal of Pain, ISSN 1877-8860, E-ISSN 1877-8879Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    There are associations between pain, comorbidity and risk of falling, and falling increases the risk of mortality in older persons, but few studies have investigated the development of pain as a result of impaired physical function. The aim of this study was to examine possible associations between weak physical performance and the development of musculoskeletal pain that interferes with normal life in a sample of older adults. The sample derived from a national, longitudinal multicenter study; the Swedish National Study on Ageing and Care; SNAC-B. The participants (n = 490) were between 60 and 78 years at the baseline examinations. Three variables were chosen for the exposure physical function, from the baseline examinations; One Leg Stand, Grip strength and Sit-to-Stand. The outcome musculoskeletal pain that interferes with normal life was measured using EQ5D and SF-12 6 years later, and logistic regression was used to investigate possible associations between the exposures and the outcome. Maximum grip strength (Grippit) was inversely associated with musculoskeletal pain that interferes with normal life (OR 2.31; 95% CI 1.15-4.61), and One-Leg Stand and Sit-to-Stand were not associated with the development of pain (OR 1.30; 95% CI 0.64-2.64) and (OR 0.91; 95% CI 0.45-1.86), respectively. Weak grip strength was inversely associated with the development of musculoskeletal pain that interferes with normal life in older adults. Impaired proprioceptive function, strength and mobility in elderly with pain have been found in earlier research. Since pain increases the risk of falling, it is important to investigate if it may develop as a function of an impaired physical function. The results of the present study could be of importance for future prevention programs aiming to protect elderly from falling. © 2019 Scandinavian Association for the Study of Pain.

    Prevalence of unknown and untreated arrhythmias in an older outpatient population screened by wireless long-term recording ECG2016Ingår i: Clinical Interventions in Aging, ISSN 1176-9092, E-ISSN 1178-1998, Vol. 11, s. 1083-1090Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Purpose: With longer life expectancies, the prevalence of arrhythmias is increasing; thus, there is a need for new methods to screen the older outpatient population. This population-based study describes the prevalence of arrhythmias in 200 outpatients aged. 66 years. We also investigated the feasibility of wireless long-term recording (LTR) using the ECG-BodyKom (R). Methods: Two hundred elderly persons aged 66-93 years were recruited from the Swedish National Study on Aging and Care in 2010-2013, and data were collected via wireless LTR ECG-BodyKom. Results: Screening with the LTR ECG revealed that persistent atrial fibrillation (AF) occurred in 10% of the outpatient population aged. 66 years. Paroxysmal AF occurred in 5.5% of the population, with no difference between younger (60-80 years) and older (>80 years) elderly participants. Furthermore, all patients with paroxysmal AF had a CHA(2)DS(2)VASc score of >= 2 and were therefore potential candidates for follow-up and medical examination. LTR ECG-BodyKom can be considered a feasible method to screen for arrhythmias in older outpatient populations. This simple method requires little of the user, and there was high satisfaction with the equipment and a good overall experience wearing it. Conclusion: The increasing occurrence of arrhythmias in the older population, as well as the high number of untreated cases of arrhythmias such as persistent AF and paroxysmal AF, poses a challenge for health care. Therefore, it is essential to develop effective strategies for their prevention and treatment.

    Older individuals’ need for knowledge and follow-up about their chronic atrial fibrillation, lifelong medical treatment and medical controls2017Ingår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 31, nr 4, s. 1022-1030Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Older individuals with chronic atrial fibrillation (AF) often experience physical symptoms and feel psychologically unwell. In addition, these persons are prescribed lifelong medical treatment that requires regular monitoring. Through 11 individual interviews, this interpretive description study aimed to explore and describe lifelong medical treatment and the need for medical controls as experienced from the perspective of older individuals living with chronic AF. The interviews were performed during 2014–2015; furthermore, they were recorded, transcribed verbatim and analysed for thematic patterns using thematic analysis inspired by Braun and Clarke. Ethical standards were followed throughout the study. The findings revealed one main theme: ‘ambivalence in the need of knowledge’ showing that lifelong medical treatment and the need for medical controls, in general, meant experiencing feelings of ‘it doesn't matter, but it does matter’ and ‘being in the hands of the healthcare system’. The older persons lacked knowledge about their condition, which generated poor insight into their medical treatment and this in turn affected their daily life. They had thoughts and questions about their medication, but did not have an opportunity to ask the questions because of lack of follow-up from the healthcare system. The findings underscore the negative impact chronic AF has on older people's life and emphasises the need for follow-up and providing information from health care to these individuals. © 2017 Nordic College of Caring Science

    Prevalence and Incidence of Atrial Fibrillation and Other Arrhythmias in the General Older Population: Findings From the Swedish National Study on Aging and Care2019Ingår i: Gerontology and geriatric medicine, E-ISSN 2333-7214, Vol. 5Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To study the prevalence and cumulative incidence of arrhythmias in the general population of adults aged 60 and older over a 6-year period. Study Design and Setting: Data were taken from the Swedish National Study on Aging and Care (SNAC), a national, longitudinal, multidisciplinary study of the general elderly population (defined as 60 years of age or older). A 12-lead resting electrocardiography (ECG) was performed at baseline and 6-year follow-up. Results: The baseline prevalence of atrial fibrillation (AF) was 4.9% (95% confidence interval [CI] = [4.5%, 5.5%]), and other arrhythmias including ventricular premature complexes (VPCs), supraventricular tachycardia (SVT), and supraventricular extrasystole (SVES) were seen in 8.4% (7.7%, 9.0%) of the population. A first- or second-degree atrioventricular (AV) block was found in 7.1% of the population (95% CI = [6.5%, 7.7%]), and there were no significant differences between men and women in baseline arrhythmia prevalence. The 6-year cumulative incidence of AF was 4.1% (95% CI = [3.5%, 4.9%]), or 6.9/1,000 person-years (py; 95% CI = [5.7, 8.0]). The incidence of AF, other arrhythmias, AV block, and pacemaker-induced rhythm was significantly higher in men in all cohorts except for the oldest. Conclusion: Our data highlight the prevalence and incidence of arrhythmias, which rapidly increase with advancing age in the general population.

    Prevalence of sleep problems and pain among the elderly in Sweden2012Ingår i: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 16, nr 2, s. 180-83Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background/Objectives: Sleep problems and pain are common among the elderly and have been shown to affect quality of life. The objectives were to determine the prevalence of sleep problems and pain among the elderly and to compare the two factors in relation to age and gender. Design: A cross-sectional study based on baseline material collected by the Swedish National Study on Aging and Care in Blekinge (SNACBlekinge). Setting: The data were gathered from questionnaires distributed between the years 2001 and 2003 in the municipality of Karlskrona, Sweden. Participants: The participants comprised 1402 Swedish men and women aged 60-96. Results: Of all the participants 70 percent met the criteria for sleep problems and 62 percent indicated some experience of pain during the preceding 4 weeks. Both sleep problems and pain were more frequent among women than men and sleep problems tended to be more common with increasing age. Among the participants who experienced pain during the preciding 4 weeks 77 percent suffered from sleep problems. Conclusions: Sleep problems and pain are common among older people. Furthermore it is common to suffer from sleep problems when pain has been experienced during the preciding 4 weeks.

    Depression and exercise in elderly men and women: findings from the Swedish national study on aging and care.2007Ingår i: Journal of Aging and Physical Activity, ISSN 1063-8652, E-ISSN 1543-267X, Vol. 15, nr 1, s. 41-55Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    This study investigated the relationship between light and strenuous exercise and depression, as well as gender differences in this relationship, in a representative sample of 860 elderly Swedish suburb-dwelling men and women in age cohorts from 60 to 96 years, drawn from among participants in the Swedish National Aging and Care study. The relationship between depression and self-reported changes in exercise status over time was also examined. Exercise activities were measured with four survey questions, and depression, with the Montgomery Asberg Depression Rating Scale. The inactive elderly had higher depression scores than more active individuals, both in terms of light and strenuous exercise. The continuously active group had lower depression scores than both continuously inactive individuals and individuals reporting a shift from activity to inactivity during the preceding year. Light exercise had a somewhat stronger effect on depression for women.

    Safety profile of the adjuvanted recombinant zoster vaccine: Pooled analysis of two large randomised phase 3 trials2019Ingår i: Vaccine, ISSN 0264-410X, E-ISSN 1873-2518, Vol. 37, nr 18, s. 2482-2493Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background: The ZOE-50 (NCT01165177) and ZOE-70 (NCT01165229) phase 3 clinical trials showed that the adjuvanted recombinant zoster vaccine (RZV) was ≥90% efficacious in preventing herpes zoster in adults. Here we present a comprehensive overview of the safety data from these studies. Methods: Adults aged ≥50 (ZOE-50) and ≥70 (ZOE-70) years were randomly vaccinated with RZV or placebo. Safety analyses were performed on the pooled total vaccinated cohort, consisting of participants receiving at least one dose of RZV or placebo. Solicited and unsolicited adverse events (AEs) were collected for 7 and 30 days after each vaccination, respectively. Serious AEs (SAEs) were collected from the first vaccination until 12 months post-last dose. Fatal AEs, vaccination-related SAEs, and potential immune-mediated diseases (pIMDs) were collected during the entire study period. Results: Safety was evaluated in 14,645 RZV and 14,660 placebo recipients. More RZV than placebo recipients reported unsolicited AEs (50.5% versus 32.0%); the difference was driven by transient injection site and solicited systemic reactions that were generally seen in the first week post-vaccination. The occurrence of overall SAEs (RZV: 10.1%; Placebo: 10.4%), fatal AEs (RZV: 4.3%; Placebo: 4.6%), and pIMDs (RZV: 1.2%; Placebo: 1.4%) was balanced between groups. The occurrence of possible exacerbations of pIMDs was rare and similar between groups. Overall, except for the expected local and systemic symptoms, the safety results were comparable between the RZV and Placebo groups irrespective of participant age, gender, or race. Conclusions: No safety concerns arose, supporting the favorable benefit-risk profile of RZV. © 2019 GlaxoSmithKline Biologicals SA

    Prognosis of Dementia Employing Machine Learning and Microsimulation Techniques: A Systematic Literature Review2016Ingår i: Procedia Computer Science / [ed] Martinho R.,Rijo R.,Cruz-Cunha M.M.,Bjorn-Andersen N.,Quintela Varajao J.E., Elsevier, 2016, Vol. 100, s. 480-488Konferensbidrag (Refereegranskat)
    Abstract [en]

    OBJECTIVE: The objective of this paper is to investigate the goals and variables employed in the machine learning and microsimulation studies for the prognosis of dementia. METHOD: According to preset protocols, the Pubmed, Socups and Web of Science databases were searched to find studies that matched the defined inclusion/exclusion criteria, and then its references were checked for new studies. A quality checklist assessed the selected studies, and removed the low quality ones. The remaining ones (included set) had their data extracted and summarized. RESULTS: The summary of the data of the 37 included studies showed that the most common goal of the selected studies was the prediction of the conversion from mild cognitive impairment to Alzheimer's Disease, for studies that used machine learning, and cost estimation for the microsimulation ones. About the variables, neuroimaging was the most frequent used. CONCLUSIONS: The systematic literature review showed clear trends in prognosis of dementia research in what concerns machine learning techniques and microsimulation.

    Bone age assessment with various machine learning techniques: A systematic literature review and meta-analysis2019Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 14, nr 7, artikel-id e0220242Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background The assessment of bone age and skeletal maturity and its comparison to chronological age is an important task in the medical environment for the diagnosis of pediatric endocrinology, orthodontics and orthopedic disorders, and legal environment in what concerns if an individual is a minor or not when there is a lack of documents. Being a time-consuming activity that can be prone to inter- and intra-rater variability, the use of methods which can automate it, like Machine Learning techniques, is of value. Objective The goal of this paper is to present the state of the art evidence, trends and gaps in the research related to bone age assessment studies that make use of Machine Learning techniques. Method A systematic literature review was carried out, starting with the writing of the protocol, followed by searches on three databases: Pubmed, Scopus and Web of Science to identify the relevant evidence related to bone age assessment using Machine Learning techniques. One round of backward snowballing was performed to find additional studies. A quality assessment was performed on the selected studies to check for bias and low quality studies, which were removed. Data was extracted from the included studies to build summary tables. Lastly, a meta-analysis was performed on the performances of the selected studies. Results 26 studies constituted the final set of included studies. Most of them proposed automatic systems for bone age assessment and investigated methods for bone age assessment based on hand and wrist radiographs. The samples used in the studies were mostly comprehensive or bordered the age of 18, and the data origin was in most of cases from United States and West Europe. Few studies explored ethnic differences. Conclusions There is a clear focus of the research on bone age assessment methods based on radiographs whilst other types of medical imaging without radiation exposure (e.g. magnetic resonance imaging) are not much explored in the literature. Also, socioeconomic and other aspects that could influence in bone age were not addressed in the literature. Finally, studies that make use of more than one region of interest for bone age assessment are scarce. Copyright: © 2019 Dallora et al.

    Machine learning and microsimulation techniques on the prognosis of dementia: A systematic literature review2017Ingår i: PLoS ONE, ISSN 1932-6203, E-ISSN 1932-6203, Vol. 12, nr 6, artikel-id e0179804Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Background Dementia is a complex disorder characterized by poor outcomes for the patients and high costs of care. After decades of research little is known about its mechanisms. Having prognostic estimates about dementia can help researchers, patients and public entities in dealing with this disorder. Thus, health data, machine learning and microsimulation techniques could be employed in developing prognostic estimates for dementia. Objective The goal of this paper is to present evidence on the state of the art of studies investigating and the prognosis of dementia using machine learning and microsimulation techniques. Method To achieve our goal we carried out a systematic literature review, in which three large databases -Pubmed, Socups and Web of Science were searched to select studies that employed machine learning or microsimulation techniques for the prognosis of dementia. A single backward snowballing was done to identify further studies. A quality checklist was also employed to assess the quality of the evidence presented by the selected studies, and low quality studies were removed. Finally, data from the final set of studies were extracted in summary tables. Results In total 37 papers were included. The data summary results showed that the current research is focused on the investigation of the patients with mild cognitive impairment that will evolve to Alzheimer's disease, using machine learning techniques. Microsimulation studies were concerned with cost estimation and had a populational focus. Neuroimaging was the most commonly used variable. Conclusions Prediction of conversion from MCI to AD is the dominant theme in the selected studies. Most studies used ML techniques on Neuroimaging data. Only a few data sources have been recruited by most studies and the ADNI database is the one most commonly used. Only two studies have investigated the prediction of epidemiological aspects of Dementia using either ML or MS techniques. Finally, care should be taken when interpreting the reported accuracy of ML techniques, given studies' different contexts. © 2017 Dallora et al.This is an open access article distributed under the terms of the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.

    Tooth loss and cognitive functions among older adults2014Ingår i: Acta Odontologica Scandinavica, ISSN 0001-6357, E-ISSN 1502-3850, Vol. 72, nr 8, s. 639-644Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Objective. To evaluate the association between the number of teeth and cognitive functions adjusted for age and education level in a cohort of older adults living in Sweden. Materials and methods. The study employed a cross-sectional design in which 1147 individuals between 60-96 years underwent a clinical oral examination. The cognitive functions were assessed using Mini-Mental State Examination (MMSE) and Clock-test. The level of education was obtained from a questionnaire. Data were subjected to Chi-square tests and multivariate logistic regression analyses were employed, grouping the different variables into pre-determined categories. Results. The co-variables age and education were significantly associated with the number of teeth (p < 0.05). The multivariate logistic regression analysis revealed that the association between the number of teeth and the cognitive functions persisted even after adjusting for age and level of education. Conclusions. The findings suggest that the presence of teeth may be of importance for cognitive abilities in older adults.

    Longitudinal evaluation of periodontitis and development of cognitive decline among older adults2018Ingår i: Journal of Clinical Periodontology, ISSN 0303-6979, E-ISSN 1600-051X, Vol. 45, nr 10, s. 1142-1149Artikel i tidskrift (Refereegranskat)
    Abstract [en]

    Aim: To determine whether having periodontitis is associated with cognitive decline among older adults. Material and Methods: A prospective population study of older adults, Swedish National Study on Ageing and Care, (SNAC) provided repeated registrations of cognitive functions. Cognitive decline was defined as ≥3-points deterioration from a predetermined level at baseline, using the Mini-Mental State Examination (MMSE). Between 2001 and 2003, 715 individuals had a medical as well as a clinical and radiographic dental examination. The individuals were re-examined after 6 years. Periodontitis was defined as ≥4 mm bone loss at ≥30% of tooth sites. Social variables were captured from questionnaires. Results: The multivariate logistic regression analysis demonstrated a statistically significant association between prevalence of periodontitis and cognitive decline after adjustments of confounding factors of importance. Conclusions: A history of periodontitis may be of importance for cognitive functions among older adults. © 2018 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd
