    Histopathological and immunocytochemical studies in age-associated dementias: the importance of rigorous histopathological criteria for classification of progressive dementia disorders1985Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Dementia is an age-associated organic brain disorder, recogniz­able by the essential features of psychological or behavioral abnormality associated with permanent dysfunction of the brain interfering with social and occupational functioning.

    There are two clinical and three histopathological forms of dementia 1) primary degenerative dementia, (PDD), or Alzhei­mer's dementia/Senile dementia of Alzheimers type (AD/SDAT) which is associated with clinical features of uniform progres­sion and insidious onset of symptoms and histopathologically i- dentified by the occurrence of neurofibrillary tangles (NFT) and senile/neuritic plaques (SP/NP) in various cortical and subcor- tical regions; 2) vascular dementia, or multi-infarct dementia (MID), which is associated with clinical features of stepwise progress and patchy distribution of deficits, and histopatholo­gically identified by the occurrence of multiple large and/or small haemorrhagic and/or ischaemic infarcts in various cortical and subcortical regions and 3) intermediate form of dementia or "mixed” ("combined") dementia (AD-MID), which is histopatho- logically associated with the coexistance of symptoms and le­sions observed in AD/SDAT and MID, and clinically referred to the MID group. The DSM-III criteria separate the demented into two groups, AD/SDAT and MID, while there are no unique clinical criteria for the AD-MID patients. The clinical diagnosis of dementia according to the DSM-III criteria was shown to be in­sufficient . Histopathological diagnostic criteria were postu­lated by us for 1) pathological changes developing in mentallyunimpaired ageing, 2) AD/ SPAT, 3) MID and 4) AD-MID.

    These histopathological classes could be separated, by means of multivariate data analysis. The pathology in AD-MID was shown not to be merely a linear combination of the AD/SDATand MID pathology.

    Intrathecal synthesis of Ig, oligoclonal bands or other abnormal proteins in the CSF could not be demonstrated in aged non-demen- ted and demented patients.

    The blood-cerebrospinal barrier (B-CSF-B) or blood-brain barrier (BBB) function alters with age and this alteration was shown to be more pronounced in MID and AD-MID patients. In MID and AD-MID patients the BBB alteration involves primarily the grey matter while in AD/SDAT patients the alteration would appear to involve only the white matter. The BBB dysfunction and a possible complement activation, either through antibody-anti- gen activation or other complement activators, was visualized in MID and AD-MID patients as perivascular serum protein depo­sits in the grey matter, always with a capillary in the center. The occurrence of some serum proteins in plaques, and the previously descibed localization of plaques in close relation­ship to the capillaries, suggest that altered BBB function and serum factors may be involved in the etiology and maturation of plaques while the etiology and maturation of tangles may not be directly dependent on these factors, as they were never labelled with any of the antisera studied.

    Constructions of various femininities among the oldest old women2006Inngår i: Health Care for Women International, ISSN 0739-9332, E-ISSN 1096-4665, Vol. 27, nr 10, 853-872 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    This study forms part of the Ume 85+ Study, and the aim was to explore various gendered constructions of femininities among the oldest old women. Femininities are seen as various ways of shaping oneself as a woman in relation to the impact of historical, social, and cultural circumstances. Thematic narratives were analyzed using qualitative content analysis. Through interpreting these narratives in the light of gender theories, we were able to discern four femininities: “being connected,” “being an actor,” “living in the shadow of others,” and “being alienated.” The oldest old women displayed complex outlooks on femininities, and no femininity was interpreted as being in the center related to the other femininities. Further research is needed in order to disclose the complexity of femininities related to factors such as social class, ethnicity, and financial situation among the oldest old, and to acquire a greater knowledge of various femininities.

    Glucose but not insulin or insulin resistance is associated with memory performance in middle-aged non-diabetic women: a cross sectional study2015Inngår i: Diabetology and Metabolic Syndrome, ISSN 1758-5996, Vol. 7, 20Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Elevated concentrations of plasma glucose appear to play a role in memory impairment, and it has been suggested that insulin might also have a negative effect on cognitive function. Our aim was to study whether glucose, insulin or insulin resistance are associated with episodic or semantic memory in a non-diabetic and non-demented population. 

    Methods: We linked and matched two population-based data sets identifying 291 participants (127 men and 164 women, mean age of 50.7 +/- 8.0 years). Episodic and semantic memory functions were tested, and fasting plasma insulin, fasting plasma glucose, and 2-hour glucose were analysed along with other potential influencing factors on memory function. Since men and women display different results on memory functions they were analysed separately. Insulin resistance was calculated using the HOMA-IR method. 

    Results: A higher fasting plasma glucose concentration was associated with lower episodic memory in women (r = -0.08, 95% CI -0.14; -0.01), but not in men. Plasma insulin levels and insulin resistance were not associated with episodic or semantic memory in women or in men after adjustments for age, fasting glucose, 2-hour glucose, BMI, education, smoking, cardiovascular disease, hypertension, cholesterol, and physical activity. 

    Conclusions: This indicates that fasting glucose but not insulin, might have impact on episodic memory in middle-aged women.

    Small molecule inhibitors of type III secretion in Yersinia block the Chlamydia pneumoniae infection cycle2007Inngår i: FEBS Lett, ISSN 0014-5793, Vol. 581, nr 4, 587-595 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Intracellular parasitism by Chlamydiales is a complex process involving transmission of metabolically inactive particles that differentiate, replicate, and re-differentiate within the host cell. A type three secretion system (T3SS) has been implicated in this process. We have here identified small molecules of a chemical class of acylated hydrazones of salicylaldehydes that specifically blocks the T3SS of Chlamydia. These compounds also affect the developmental cycle showing that the T3SS has a pivotal role in the pathogenesis of Chlamydia. Our results suggest a previously unexplored avenue for development of novel anti-chlamydial drugs.

    Self-rated health and all-cause and cause-specific mortality of older adults: Individual data meta-analysis of prospective cohort studies in the CHANCES Consortium2017Inngår i: Maturitas, ISSN 0378-5122, E-ISSN 1873-4111, Vol. 103, 37-44 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: To evaluate, among the elderly, the association of self-rated health (SRH) with mortality, and to identify determinants of self-rating health as “at-least-good”.

    Study design: Individual data on SRH and important covariates were obtained for 424,791 European and United States residents, ≥60 years at recruitment (1982–2008), in eight prospective studies in the Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES). In each study, adjusted mortality ratios (hazard ratios, HRs) in relation to SRH were calculated and subsequently combined with random-effect meta-analyses.

    Main outcome measures: All-cause, cardiovascular and cancer mortality.

    Results: Within the median 12.5 years of follow-up, 93,014 (22%) deaths occurred. SRH “fair” or “poor” vs. “at-least-good” was associated with increased mortality: HRs 1.46 (95% CI 1·23–1.74) and 2.31 (1.79–2.99), respectively. These associations were evident: for cardiovascular and, to a lesser extent, cancer mortality, and within-study, within-subgroup analyses. Accounting for lifestyle, sociodemographic, somatometric factors and, subsequently, for medical history explained only a modest amount of the unadjusted associations. Factors favourably associated with SRH were: sex (males), age (younger-old), education (high), marital status (married/cohabiting), physical activity (active), body mass index (non-obese), alcohol consumption (low to moderate) and previous morbidity (absence).

    Conclusion: SRH provides a quick and simple tool for assessing health and identifying groups of elders at risk of early mortality that may be useful also in clinical settings. Modifying determinants of favourably rating health, e.g. by increasing physical activity and/or by eliminating obesity, may be important for older adults to “feel healthy” and “be healthy”.

    Duration of Postoperative Delirium Is an Independent Predictor of 6-Month Mortality in Older Adults After Hip Fracture2014Inngår i: Journal of The American Geriatrics Society, ISSN 0002-8614, E-ISSN 1532-5415, Vol. 62, nr 7, 1335-1340 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: To evaluate the association between number of days with delirium and 6-month mortality in elderly adults after hip fracture surgery. DESIGN: Prospective cohort study with 6-month follow-up. SETTING: Orthogeriatric Unit (OGU). PARTICIPANTS: Individuals (mean age = 84.3 +/- 6.4) admitted to the OGU between October 2011 and April 2013 with hip fracture (N = 199). MEASUREMENTS: Postoperative delirium (POD) was assessed daily using the Confusion Assessment Method algorithm and the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, criteria. Multivariable Cox regression models were used to evaluate the association between POD of and 6-month mortality after surgery, after adjustment for covariates including age, prefracture residence, Katz activity of daily living score, New Mobility score, diagnosis of prefracture dementia, American Society of Anesthesiologists score, albumin serum levels, Charlson Comorbidity Index, and length of OGU stay. RESULTS: Fifty-seven participants (28.6%) developed POD. In the 6-month period after surgery, 35 (17.6%) participants died: 16 of 57 (28.1%) with POD and 19 / of 142 (13.4%) with no POD. The average duration of POD was 2.0 +/- 3.2 days for participants who died and 0.7 +/- 1.8 days for those who survived (P < .001). After adjusting for covariates, each day of POD in the OGU increased the hazard of dying at 6 months by 17% (hazard ratio = 1.17, 95% confidence interval = 1.07-1.28). CONCLUSION: In older adults undergoing hip fracture surgery, duration of POD is an important prognostic factor for 6-month mortality. Efforts to reduce duration of POD are therefore crucial for these individuals.

    Depression among the very old with dementia2011Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 23, nr 5, 756-763 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: The aim of this study was to investigate the prevalence of depression among very old individuals with dementia compared to those without dementia and to examine if there were any differences regarding associated factors between people with or without depression in these conditions.

    Methods: In a population-based study in Sweden, 363 participants aged 85 years and above, were evaluated for depression and dementia.

    Results: The prevalence of depression was significantly higher among the people with dementia than without dementia, 43% vs. 24% (p < 0.001). Approximately 2/3 of the depressed in both groups used antidepressants and of those, approximately 50% had responded. Depression in the group without dementia was, among other factors, associated with higher total number of medication, the use of significant more analgesics and benzodiazepines, loneliness, inability of going outside and recent loss of child. The loss of a child was the only factor that was independently associated with depression in those with dementia.

    Conclusions: The present study confirms that in the very old, depression is more common among people with dementia than without dementia. A large proportion, both with and without dementia, are under-diagnosed and untreated, and in addition many subjects in both groups studied were non-responders to treatment. Many of the factors associated with depression among people without dementia in this study were not associated with depression among those with dementia, thus supporting the theory that the spectrum of associated factors for depression in dementia seems to be different from that for depression in people without dementia.

    Co-morbidities, complications and causes of death among people with femoral neck fracture: a three-year follow-up study2016Inngår i: BMC Geriatrics, ISSN 1471-2318, E-ISSN 1471-2318, Vol. 16, 120Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: The poor outcome after a hip fracture is not fully understood. The aim of the study was to describe the prevalence of co-morbidities, complications and causes of death and to investigate factors that are able to predict mortality in old people with femoral neck fracture. Methods: Data was obtained from a randomized, controlled trial with a 3-year follow-up at Umea University Hospital, Sweden, which included 199 consecutive patients with femoral neck fracture, aged >= 70 years. The participants were assessed during hospitalization and in their homes 4, 12 and 36 months after surgery. Medical records and death certificates were analysed. Results: Multivariate analysis revealed that cancer, dependence in P-ADL (Personal Activities of Daily Living), cardiovascular disease, dementia at baseline or pulmonary emboli or cardiac failure during hospitalization were all independent predictors of 3-year mortality. Seventy-nine out of 199 participants (40 %) died within 3 years. Cardiovascular events (24 %), dementia (23 %), hip-fracture (19 %) and cancer (13 %) were the most common primary causes of death. In total, 136 participants suffered at least one urinary tract infection; 114 suffered 542 falls and 37 sustained 56 new fractures, including 13 hip fractures, during follow-up. Conclusion: Old people with femoral neck fracture have multiple co-morbidities and suffer numerous complications. Thus randomized intervention studies should focus on prevention of complications that might be avoidable such as infections, heart diseases, falls and fractures.

    Attention in Older Adults: A Normative Study of the Integrated Visual and Auditory Continuous Performance Test for Persons Aged 70 Years2015Inngår i: Clinical Neuropsychologist (Neuropsychology, Development and Cognition: Section D), ISSN 1385-4046, E-ISSN 1744-4144, Vol. 29, nr 5, 595-610 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: Our objective was to present normative data from 70-year-olds on the Integrated Visual and Auditory Continuous Performance Test (IVA), a computerized measure of attention and response control. Method: 640 participants (330 men and 310 women), all aged 70years, completed the IVA, as well as the Mini-Mental State Examination and the Geriatric Depression Scale. Results: Data were stratified by education and gender. Education differences were found in 11 of 22 IVA scales. Minor gender differences were found in six scales for the high-education group, and two scales for the low-education group. Comparisons of healthy participants and participants with stroke, myocardial infarction, or diabetes showed only minor differences. Correlations among IVA scales were strong (all r > .34, p < .001), and those with the widely used Mini-Mental State Examination were weaker (all r < .21, p < .05). Skewed distributions of normative data from primary IVA scales measuring response inhibition (Prudence) and inattention (Vigilance) represent a weakness of this test. Conclusions: This study provides IVA norms for 70-year-olds stratified by education and gender, increasing the usability of this instrument when testing persons near this age. The data presented here show some major differences from original IVA norms, and explanations for these differences are discussed. Explanations include the broad age-range used in the original IVA norms (66-99years of age) and the passage of 15years since the original norms were collected.

    Fatigue after traumatic brain injury is linked to altered striato-thalamic-cortical functioning2017Inngår i: Brain Injury: Accepted Abstracts from the International Brain Injury Association’s 12th World Congress on Brain Injury, 2017, Vol. 31, 755-755 s.Konferansepaper (Fagfellevurdert)
    Abstract [en]

    Mental fatigue is a common symptom in the chronic phase of traumatic brain injury. Despite its high prevalence, no treatmentis available for this disabling symptom, and the mechanisms underlying fatigue are poorly understood. Some studies have suggested that fatigue in traumatic brain injury and other neurological disorders might reflect dysfunction within striato-thalamic-cortical loops. In the present study, we investigated whether functional magnetic resonance imaging(fMRI) can be used to detect chronic fatigue after traumatic brain injury (TBI), with emphasis on the striato-thalamic cortical-loops. We included patients who had suffered traumatic brain injury (n = 57, age range 20–64 years) and experienced mental fatigue > 1 year post injury (mean = 8.79 years, SD = 7.35), and age- and sex-matched healthycontrols (n = 27, age range 25–65 years). All participants completed self-assessment scales of fatigue and other symptoms, underwent an extensive neuropsychological test battery and performed a fatiguing 27-minute attention task (the modified Symbol Digit Modalities Test) during fMRI. Accuracy did not differ between groups, but reaction times were slower in the traumatic brain injury group (p < 0.001). Patients showed a greater increase in fatigue than controls from before to after task completion (p < 0.001). Patients showed less fMRI blood oxygen level–dependent activity in several a priori hypothesized regions (family-wise error corrected,p < 0.05), including the bilateral caudate, thalamus and anterior insula. Using the left caudate as a region of interest and testing for sensitivity and specificity, we identified 91% of patients and 81% of controls. As expected, controls showed decreased activation over time in regions of interest—the bilateral caudate and anterior thalamus (p < 0.002, uncorrected)—whereas patients showed no corresponding activity decrease. These results suggest that chronic fatigue after TBI is linked to altered striato-thalamic-cortical functioning. The high precision of fMRI for the detection of fatigue is of great clinical interest, given the lack of objective measures for the diagnosis of fatigue.

    Using Functional Magnetic Resonance Imaging to Detect Chronic Fatigue in Patients With Previous Traumatic Brain Injury: Changes Linked to AlteredStriato-Thalamic-Cortical FunctioningInngår i: The journal of head trauma rehabilitation, ISSN 0885-9701, E-ISSN 1550-509XArtikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To investigate whether functional magnetic resonance imaging (fMRI) can be used to detect fatigue after traumatic brain injury (TBI).

    Setting: Neurorehabilitation clinic.

    Participants: Patients with TBI (n = 57) and self-experienced fatigue more than 1 year postinjury, and age- and gender-matched healthy controls (n = 27).

    Main Measures: Self-assessment scales of fatigue, a neuropsychological test battery, and fMRI scanning during performance of a fatiguing 27-minute attention task.

    Results: During testing within the fMRI scanner, patients showed a higher increase in self-reported fatigue than controls from before to after completing the task (P < .001).The patients also showed lower activity in several regions, including bilateral caudate, thalamus, and anterior insula (all P < .05). Furthermore, the patients failed to display decreased activation over time in regions of interest: the bilateral caudate and anterior thalamus (all P < .01). Left caudate activity correctly identified 91% of patients and 81% of controls, resulting in a positive predictive value of 91%.

    Conclusion: The results suggest that chronic fatigue after TBI is associated with altered striato-thalamic-cortical functioning. It would be of interest to study whether fMRI can be used to support the diagnosis of chronic fatigue in future studies.

    The effects of (-)-OSU6162 on chronic fatigue in patients with traumatic brain injury: a randomized controlled trial2017Inngår i: The journal of head trauma rehabilitation, ISSN 0885-9701, E-ISSN 1550-509X, Vol. 32, nr 2, E46-E54 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVE: To examine the effects of the monoaminergic stabilizer (-)-OSU6162 on mental fatigue in patients with traumatic brain injury.

    SETTING: Single-center Neurorehabilitation Clinic.

    DESIGN: Randomized, double-blind, placebo-controlled trial.

    PARTICIPANTS: Sixty-four subjects with traumatic brain injury were randomized to treatment (n = 33) and placebo (n = 31).

    MAIN MEASURES: The effects of (-)-OSU6162 at a dose of 15 mg twice a day were evaluated using self-assessment scales and neuropsychological tests measuring mental fatigue.

    RESULTS: No difference between groups was observed on any scale at baseline. At follow-up, both groups showed significant improvement on the Fatigue Severity Scale and the Mental Fatigue Scale (both Ps < .01). Similarly, the performance of both groups increased significantly on many neuropsychological tests. However, no significant between-group difference in changes on these scales was observed before or after adjustment for confounders except for one neuropsychological test favoring the control group. Sensitivity analyses showed significantly greater changes in levels of prolactin and folic acid and heart rate (all Ps < .05) in the treatment group. The mean plasma concentration after 4 weeks of treatment was 0.14 (range, 0.01-0.32) μM, which was lower than expected.

    INTERPRETATION: Treatment with (-)-OSU6162 had no significant effect on mental fatigue in patients with traumatic brain injury compared with placebo.

    Alendronate use and the risk of nonvertebral fracture during glucocorticoid therapy: a retrospective cohort study.2017Inngår i: Journal of Clinical Endocrinology and Metabolism, ISSN 0021-972X, E-ISSN 1945-7197Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Context: Glucocorticoids increase the risk of nonvertebral fracture, but no clinical trial has shown that nonvertebral fractures can be prevented by co-administration of an anti-osteoporotic drug.

    Objective: To estimate the effect of alendronate on the risk of nonvertebral fracture in older adults taking oral glucocorticoids.

    Design: Retrospective cohort study using national Swedish registers.

    Setting: Hospitalized care and ambulatory specialist care.

    Patients: Among adults aged 50 years or older (N=3,347,959), we identified those who initiated oral glucocorticoid therapy from 2006 through 2011 (≥2.5 mg/day of prednisone or equivalent for ≥91 days). The final analysis included 16,890 alendronate users and 16,890 nonusers, who were matched using time-dependent propensity scores.

    Main Outcome Measure: Nonvertebral fracture. This was not pre-specified.

    Results: Over a median follow-up of 14.5 months, the incidence rate of nonvertebral fracture was 2.0 cases per 100 person-years in alendronate users and 2.4 cases in nonusers. This difference corresponded to a 16% lower rate in users (hazard ratio 0.84, 95% confidence interval 0.75 to 0.94). For hip fractures specifically, the rate was 34% lower in alendronate users relative to nonusers (hazard ratio 0.66, 95% confidence interval 0.55 to 0.78). The association of alendronate use with a lower risk of nonvertebral fracture was strongest in patients who received high doses of glucocorticoid.

    Conclusion: Alendronate use was associated with a lower risk of nonvertebral fracture, including hip fracture. Similar, but not statistically significant, associations have been reported in meta-analyses of clinical trials.

    The hip fracture incidence curve is shifting to the right: a forecast of the age-quake2009Inngår i: Acta Orthopaedica, ISSN 1745-3674, E-ISSN 1745-3682, Vol. 80, nr 5, 520-524 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background The number of hip fractures has doubled in the last 30–40 years in many countries. Age-adjusted incidence has been reported to be decreasing in Europe and North America, but is there a decreasing trend in all age groups? Patients and methods This population-based study included all hip-fracture patients over 50 years of age (a total of 2,919 individuals, 31% of whom were men) admitted to Umeå University Hospital, Sweden, from 1993 through 2005. Results The incidence of hip fracture declined between the periods 1993–1996 and 2001–2005: from 706 to 625 hip fractures per 105 women and from 390 to 317 hip fractures per 105 men. However, there was a 114% increase in the number of fractures in women aged 90 or older (12 and 25 hip fractures/year, respectively, in the two time periods). For the period 2001–05, women ≥ 90 years of age accounted for almost the same numbers of hip fractures as women aged 75–79 (27 fractures/year). The rate increased during this period, from 2,700 per 105 women to 3,900 per 105 women > 90 years. In men there were declining trends for both relative and absolute numbers. Interpretation Although age-adjusted incidence declined in the population > 50 years of age, absolute fracture rate and incidence increased in the very old. Women over 90 now have the same absolute number of hip fractures every year as women aged 75–79 years. There was a right-shift in hip fracture distribution towards the oldest old, probably due to an increased number of octo/nonagenarians, a new population of particularly frail old people that hardly existed earlier. Better health among septuagenarians may also have delayed the age at which fractures occurred. This changing pattern will strain orthopedic and geriatric resources even more.

    Consequences of stroke: aspects of impairments, disabilities and life satisfaction : with special emphasis on perception and on occupational therapy1987Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Perceptual and motor functions and self-care ability after stroke were assessed within two weeks (n:109; mean age 69±10) and 4-6 years (n:75;70±9) after admission to a non-intensive care stroke unit. Sixty-two of the long-term stroke survivors reported on their life satisfaction (7 items) as experienced (in retrospect) before the stroke and at the time of the investigation. Perceptual functions and actual levels of life satisfaction were registered in 60 clinically healthy subjects aged about 60 or about 80 years.

    Both early on and late after stroke the 16 items of perceptual function were clearly grouped into two factors, which neatly fitted an ecological perceptual concept. One factor characterized low-order and the other higher-order perception. Impairments of low-order perception occurred for about 10% of the patients, whether investigated early or late after stroke. No one among the reference populations had such impairments. Higher-order perceptual impairments prevailed in 60% early on and in 57% late after stroke and were often more pronounced than those occurring in the reference populations, among whom 35% of the 60 year olds and significantly more - 77% - of the 80 year olds had such impairments. Hence, perceptual impairments are common after stroke, but slight age-dependent reductions should be considered when higher-order perceptual function is assessed and treated after stroke.

    Together with motor function, which was impaired in 52% of the early and 36% of the late stroke samples, higher-order perceptual function and to a limited extent low-order perception could predict the level of self-care ability in 70% and 62% of the early and late samples, respectively.

    Whereas levels of global and of domain specific variables of life satisfaction were similar in the two reference populations, the stroke had lead to a reduction in life satisfaction for 61% of the long-term survivors. Reductions were particularly pronounced for global life satisfaction and for satisfaction with leisure and sexuality. Although significantly associated with motor impairment and self-care disability, these reductions could not be attributed only to impairments and disability.

    The findings are discussed with particular reference to assessment and treatment in occupational therapy.

    Motor and perceptual impairments in acute stroke patients: effects on self-care ability1987Inngår i: Stroke, ISSN 0039-2499, E-ISSN 1524-4628, Vol. 18, nr 6, 1081-1086 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    The relative importance of motor, perceptual, and some cognitive functions for self-care ability was analyzed in a representative sample of 109 subjects within 2 weeks of acute stroke. Forty-nine patients (45%) were dependent or partly dependent in self-care. Profound motor dysfunction was present in 39%, low-order perceptual deficits in 10%, high-order perceptual deficits in 60%, and disorientation in time and space in 13% of the patients. There was a significant covariation between motor function and self-care ability and between low-order perception and orientation function. Low-order and high-order perception covaried only weakly. Discriminant analyses showed that the actual level of self-care proficiency could be correctly predicted in 70% of the cases by the 4 indexes of motor function, low-order perception, high-order perception, and orientation. The dominating predictor was motor function, and the next highest was high-order perception. When a program for early training is designed with the aim to alleviate long-term self-care disability after stroke, correct assessment of motor and perceptual functions in the individual stroke patient is essential.

    Perceptual function in the elderly and after stroke1988Inngår i: Scandinavian Journal of Caring Sciences, ISSN 0283-9318, E-ISSN 1471-6712, Vol. 2, nr 2, 75-79 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Perceptual function was assessed in 60 clinically healthy subjects aged about 60 (n=34) and 80 (n=26), and in stroke survivors who were assessed either early (n=109) or four to six years (n=75) after the stroke. Using two indices, one characterising low-order perception and the other higher-order perception, the clinically healthy subjects invariably had no impairment in the low-order index. Slight impairments occurred in 35% of 60-year-old and 77% of 80-year-old healthy subjects. Considerably more pronounced disturbances occurred in the stroke victims, among whom about 60% had impairment or higher-order perceptual function and about 10% had low-order perceptual deficits. Thus as higher-order perception is age dependent, it appears that in rehabilitation of stroke allowance should be made for predictable signs of advancing age.

    Thriving in relation to cognitive impairment and neuropsychiatric symptoms in Swedish nursing home residents2017Inngår i: International Journal of Geriatric Psychiatry, ISSN 0885-6230, E-ISSN 1099-1166Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: The purpose of this study was to explore relations among thriving, cognitive function, and neuropsychiatric symptoms (NPS) in nursing home residents.

    Methods: A national, cross-sectional, randomized study of Swedish nursing home residents (N = 4831) was conducted between November 2013 and September 2014. Activities of daily life functioning, cognitive functioning, NPS, and thriving were assessed with the Katz activities of daily living, Gottfries' Cognitive Scale, Nursing Home version of the Neuropsychiatric Inventory, and Thriving of Older People Scale, respectively. Individual NPS were explored in relation to cognitive function. Simple linear and multiple regression models were used to explore thriving in relation to resident characteristics.

    Results: Aggression and depressive symptoms were identified as negatively associated with thriving regardless of resident cognitive functioning. At higher levels of cognitive functioning, several factors showed associations with thriving; however, at lower levels of cognitive functioning, only the degree of cognitive impairment and the NPS was associated with thriving. Most of the individual NPS formed nonlinear relationships with cognitive functioning with higher symptom scores in the middle stages of cognitive functioning. Exceptions were elation/euphoria and apathy, which increased linearly with severity of cognitive impairment.

    Conclusions: The lower the cognitive functioning was, the fewer factors were associated with thriving. Aggression and depressive symptoms may indicate lower levels of thriving; thus, targeting these symptoms should be a priority in nursing homes.

    There is a public health demand to prevent health conditions which lead to increased morbidity and mortality among the rapidly-increasing elderly population. Data for the incidence of such conditions exist in cohort studies worldwide, which, however, differ in various aspects. The Consortium on Health and Ageing: Network of Cohorts in Europe and the United States (CHANCES) project aims at harmonizing data from existing major longitudinal studies for the elderly whilst focussing on cardiovascular diseases, diabetes mellitus, cancer, fractures and cognitive impairment in order to estimate their prevalence, incidence and cause-specific mortality, and identify lifestyle, socioeconomic, and genetic determinants and biomarkers for the incidence of and mortality from these conditions. A survey instrument assessing ageing-related conditions of the elderly will be also developed. Fourteen cohort studies participate in CHANCES with 683,228 elderly (and 150,210 deaths), from 23 European and three non-European countries. So far, 287 variables on health conditions and a variety of exposures, including biomarkers and genetic data have been harmonized. Different research hypotheses are investigated with meta-analyses. The results which will be produced can help international organizations, governments and policy-makers to better understand the broader implications and consequences of ageing and thus make informed decisions.

    Inner strength: associated with reduced prevalence of depression among older women2015Inngår i: Aging & Mental Health, ISSN 1360-7863, E-ISSN 1364-6915, Vol. 19, nr 12, 1078-1083 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objectives: The aim of this study was to explore if inner strength is independently associated with a reduced prevalence of depression after controlling for other known risk factors associated with depression.

    Methods: A population-based cross-sectional study was performed, where all women living in Åland, a Finnish self-govern island community in the Baltic Sea, aged 65 years or older were sent a questionnaire including the Geriatric Depression Scale and the Inner Strength Scale along with several other questions related to depression. Factors associated with depression were analyzed by means of multivariate logistic regression.

    Results: The results showed that 11.2% of the studied women (n = 1452) were depressed and that the prevalence increased with age and was as high as 20% in the oldest age group. Non-depressed women were more likely to never or seldom feel lonely, have a strong inner strength, take fewer prescription drugs, feeling needed, being able to engage in meaningful leisure activities, as well as cohabit.

    Conclusion: Our results showed an association between stronger inner strength and being non-depressed. This can be interpreted to mean that inner strength might have a protective effect against depression. These findings are interesting from a health-promotion perspective, yet to verify these results, further longitudinal studies are required.

    Depression in older people with and without dementia: non-pharmacological interventions and associations between psychotropic drugs and mortality2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The aim of this thesis was to investigate associations between psychotropic drug use and death, associations between functional capacity, dependency in ADL and depression, and to evaluate a non-pharmacological intervention to reduce depressive symptoms, among older people with and without dementia.

    There is limited knowledge about the risk of death associated with psychotropic drug use among those aged ≥85 years, those with dementia, or those living in residential care facilities; groups that have a higher intake of psychotropic drugs and who are also more prone to adverse drug reactions. In a representative sample of people ≥85 years (n = 992), baseline antidepressant use was not associated with an increased 5-year mortality risk when adjusting for confounding factors. A significant interaction between gender and antidepressant use was found, with a higher mortality risk in women, than in men.  When analyzing men and women separately, no significant associations were found. In a sample of older people (i.e. ≥65 years) with dementia (n = 1037), there was a significant gender difference in 2-year mortality associated with the baseline use of antidepressant drugs, with a lower mortality risk in men, than in women. In men, the mortality risk was significantly reduced with antidepressant use, while there was no significant association in women. The association between baseline use of benzodiazepines and mortality had a tendency toward an increased risk during the first year of follow-up, although this became non-significant after adjustments. In this time period, the interaction term for sex was significant, with a higher mortality risk among men than women. When the sexes were analyzed separately, no significant associations were found. No significant associations were found between baseline use of antipsychotic drugs and mortality.

    Drug treatment for depression seems to have a limited effect in older people and may have no effect in people with dementia. In order to find alternative ways of treating or preventing depression in older age, it is important to increase our knowledge about factors associated with this condition. Functional capacity and dependency in activities of daily living (ADL) are associated with depression in community-dwelling older people. However, it is uncertain whether the same associations are to be found in very old people (i.e. ≥80 years), including those with severe cognitive or physical impairments. In a heterogeneous sample (n = 392) with a high mean age, a large range of cognitive and functional capacity, a wide spectrum of dependency in ADL, and a high prevalence of comorbidities, depressive symptoms were significantly associated with functional balance capacity, but not with overall dependency in ADL. Among individual ADL tasks, dependency in transfer and dressing were associated with depressive symptoms.

    Physical exercise has shown effect sizes similar to those of antidepressants in reducing depressive symptoms among older people without dementia, with moderate–high-intensity exercise being more effective than low-intensity exercise. However, these effects are unclear among older people with dementia. Care-facility residents with dementia (n = 186) were cluster-randomized to a high-intensity functional exercise program or a non-exercise control activity conducted for 45 minutes every other weekday for 4 months. No significant difference between the exercise and control activity was found in depressive symptoms at 4 or 7 months. Among participants with high levels of depressive symptoms, reductions were observed in both the exercise and control groups at 4 and 7 months.

    In conclusion, ongoing treatment at baseline with any of the three psychotropic drug classes antidepressants, antipsychotics and benzodiazepines did not increase the risk of mortality in older people with dementia.  Neither did antidepressant drugs in very old people. In both samples, gender differences were found in the mortality risk due to antidepressant use. In those with dementia, the mortality risk due to benzodiazepine use also differed by gender. The potential risk from initial treatment and gender differences regarding mortality risk require further investigation in randomized controlled trials or in large cohort studies properly controlled for confounding factors. In older people, living in community and residential care facilities, functional capacity seems to be independently associated with depressive symptoms whereas overall ADL performance may not be associated. Dependency in the individual ADL tasks of transfer and dressing appear to be independently associated with depressive symptoms and may be an important focus for future interdisciplinary multifactorial intervention studies. Among older people with dementia living in residential care facilities, a 4-month high-intensity functional exercise program has no superior effect on depressive symptoms than a control activity. Both exercise and non-exercise group activities may reduce high levels of depressive symptoms. However, this finding must be confirmed in three-armed randomized controlled trials including control groups receiving standard care.

    Effects of a high-intensity functional exercise program on depressive symptoms among people with dementia in residential care: a randomized controlled trial2016Inngår i: International Journal of Geriatric Psychiatry, ISSN 0885-6230, E-ISSN 1099-1166, Vol. 31, nr 8, 868-878 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: The aim of this study is to evaluate the effect of a high-intensity functional exercise program on depressive symptoms among older care facility residents with dementia.

    METHODS: Residents (n = 186) with a diagnosis of dementia, age ≥ 65 years, Mini-Mental State Examination score ≥ 10, and dependence in activities of daily living were included. Participants were randomized to a high-intensity functional exercise program or a non-exercise control activity conducted 45 min every other weekday for 4 months. The 15-item Geriatric Depression Scale (GDS) and the Montgomery-Åsberg Depression Rating Scale (MADRS) were administered by blinded assessors at baseline, 4, and 7 months.

    RESULTS: No difference between the exercise and control activity was found in GDS or MADRS score at 4 or 7 months. Among participants with GDS scores ≥ 5, reductions in GDS score were observed in the exercise and control groups at 4 months (-1.58, P = 0.001 and -1.54, P = 0.004) and 7 months (-1.25, P = 0.01 and -1.45, P = 0.007). Among participants with MADRS scores ≥ 7, a reduction in MADRS score was observed at 4 months in the control group (-2.80, P = 0.009) and at 7 months in the exercise and control groups (-3.17, P = 0.003 and -3.34, P = 0.002).

    CONCLUSIONS: A 4-month high-intensity functional exercise program has no superior effect on depressive symptoms relative to a control activity among older people with dementia living in residential care facilities. Exercise and non-exercise group activities may reduce high levels of depressive symptoms.

    Functional capacity and dependency in transfer and dressing are associated with depressive symptoms in older people2014Inngår i: Clinical Interventions in Aging, ISSN 1176-9092, E-ISSN 1178-1998, Vol. 9, 249-257 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: This study examined associations between depressive symptoms and functional capacity, overall dependency in personal activities of daily living (ADLs), and dependency in individual ADL tasks, respectively, in people with a high mean age, large range of functional capacity, and wide spectrum of dependency in ADLs. Methods: Cross-sectional data from three studies were used. A total of 392 individuals living in community and residential care facilities were included. Mean age was 86.2 years, 72% were women, 75% were dependent in ADLs, 42% had depression, and 39% had dementia. Depressive symptoms were assessed with the 15-item Geriatric Depression Scale (GDS-15), functional capacity with the Berg Balance Scale (BBS), and ADLs with the Barthel ADL Index. Multiple linear regression analyses with comprehensive adjustments were performed between GDS-15 and BBS, GDS-15 and Barthel ADL Index, and GDS-15 and each individual ADL task, separately. Results: GDS-15 score was associated with BBS score (unstandardized b=-0.03, P=0.008), but not with Barthel ADL Index score (unstandardized b=-0.07, P=0.068). No significant interaction effects of sex, dementia, or living conditions were found in these associations. Among individual ADL tasks, dependency in transfer (unstandardized b=-1.03, P=0.007) and dressing (unstandardized b=-0.70, P=0.035) were associated with depressive symptoms. Conclusion: Functional capacity seems to be independently associated with depressive symptoms in older people living in community and residential care facilities, whereas overall ADL performance may not be associated. Dependency in the individual ADL tasks of transfer and dressing appear to be independently associated with depressive symptoms and may be an important focus of future interdisciplinary multifactorial intervention studies.

    Antidepressant use and mortality in very old people2016Inngår i: International psychogeriatrics, ISSN 1041-6102, E-ISSN 1741-203X, Vol. 28, nr 7, 1201-1210 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: Antidepressant treatment may increase the risk of death. The association between antidepressants and mortality has been evaluated in community-dwelling older people, but not in representative samples of very old people, among whom dementia, multimorbidity, and disability are common.

    METHODS: Umeå 85+/GERDA study participants (n = 992) aged 85, 90, and ≥95 years were followed for up to five years. Cox proportional hazard regression models were used to analyze mortality risk associated with baseline antidepressant treatment, adjusted for potential confounders.

    RESULTS: Mean age was 89 years; 27% of participants had dementia, 20% had stroke histories, 29% had heart failure, and 16% used antidepressants. In age- and sex-adjusted analyses, antidepressant use was associated with a 76% increased mortality risk (hazard ratio [HR] = 1.76; 95% confidence interval [CI], 1.41-2.19). Adding adjustment for Geriatric Depression Scale score, HR was 1.62 (95% CI, 1.29-2.03). The association was not significant when adjusting for additional confounding factors (HR = 1.08; 95% CI, 0.85-1.38). Interaction analyses in the fully adjusted model revealed a significant interaction between sex and antidepressant use (HR: 1.76; 95% CI, 1.05-2.94). Among male and female antidepressant users, the HRs for death were 0.76 (95% CI, 0.47-1.24) and 1.28 (95% CI, 0.97-1.70), respectively.

    CONCLUSION: Among very old people, baseline antidepressant treatment does not seem to be independently associated with increased mortality risk. However, the risk may be different in men and women. This difference and the potential risk of initial treatment require further investigation in future cohort studies of very old people.

    Psychotropic drug use and mortality in old people with dementia: investigating sex differences2017Inngår i: BMC Pharmacology & Toxicology, E-ISSN 2050-6511, Vol. 18, 36Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Psychotropic drugs are common among old people with dementia, and have been associated with increased mortality. Previous studies have not investigated sex differences in this risk. This study was conducted to analyse associations between the use of antipsychotics, antidepressants, and benzodiazepines and 2-year mortality in old people with dementia, and to investigate sex differences therein.

    Methods: In total, 1037 participants (74% women; mean age, 89 years) with dementia were included from four cohort studies and followed for 2 years. Data were collected through home visits and medical records. Cox proportional hazard regression models were used to analyse associations between ongoing baseline drug use and mortality. Multiple possible confounders were evaluated and adjusted for.

    Results: In fully adjusted models including data from the whole population, no association between baseline psychotropic drug use and increased 2-year mortality was seen. Significant sex differences were found in mortality associated with antidepressant use, which was protective in men, but not in women (hazard ratio [HR] 0.61, 95% confidence interval [CI] 0.40–0.92 and HR 1.09, 95% CI 0.87–1.38, respectively). The interaction term for sex was significant in analyses of benzodiazepine use, with a higher mortality risk among men than among women.

    Conclusions: Among old people with dementia, ongoing psychotropic drug use at baseline was not associated with increased mortality in analyses adjusted for multiple confounders. Sex differences in mortality risk associated with antidepressant and benzodiazepine use were seen, highlighting the need for further investigation of the impact of sex.

    Gender disparities in the pharmacological treatment of cardiovascular disease and diabetes mellitus in the very old: an epidemiological, cross-sectional survey2011Inngår i: Drugs & Aging, ISSN 1170-229X, E-ISSN 1179-1969, Vol. 28, nr 12, 993-1005 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    BACKGROUND: There are many reports of disparities in health and medical care both between women and men and between various age groups. In most cases, men receive better treatment than women and young and middle-aged people are privileged compared with the old and the very old. Cardiovascular morbidity and diabetes mellitus are common, increase with age and are often treated extensively with drugs, many of which are known to have significant adverse effects.

    OBJECTIVE: The aim of the study was to analyse gender differences in the pharmacological treatment of cardiovascular disease and diabetes among very old people.

    METHODS: The study took the form of an epidemiological, cross-sectional survey. A structured interview was administered during one or more home visits, and data were further retrieved from medical charts and interviews with relatives, healthcare staff and other carers. Home-dwelling people as well as people living in institutional care in six municipalities in the county of Västerbotten, Sweden, in 2005-7 were included in the study. Half of all people aged 85 years, all of those aged 90 years and all of those aged ≥95 years living in the selected municipalities were selected for inclusion in the study. In total, 467 people were included in the present analysis. The main study outcome measures were medical diagnoses and drug use.

    RESULTS: In total, women were prescribed a larger number of drugs than men (mean 7.2 vs 5.4, p < 0.001). Multiple logistic regression models adjusted for age and other background variables as well as relevant medical diagnoses (hypertension, heart failure) showed strong associations between female sex and prescriptions of thiazide diuretics (odds ratio [OR] 4.4; 95% CI 1.8, 10.8; p = 0.001), potassium-sparing diuretics (OR 3.5; 95% CI 1.4, 8.7; p = 0.006) and diuretics as a whole (OR 1.8; 95% CI 1.1, 2.9; p = 0.021). A similar model, adjusted for angina pectoris, showed that female sex was associated with prescription of short-acting nitroglycerin (OR 3.7; 95% CI 1.6, 8.9; p = 0.003). However, more men had been offered coronary artery surgery (p = 0.001). Of the participants diagnosed with diabetes, 55% of the women and 85% of the men used oral antihyperglycaemic drugs (p = 0.020), whereas no gender difference was seen in prescriptions of insulin.

    CONCLUSIONS: Significant gender disparities in the prescription of several drugs, such as diuretics, nitroglycerin and oral antihyperglycaemic drugs, were observed in this study of very old people. In most cases, women were prescribed more drugs than men. Men more often had undergone coronary artery surgery. These disparities could only in part be explained by differences in diagnoses and symptoms.

    Clinical and etiological studies on dementia of Alzheimer type and multiinfarct dementia1983Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    1. Clinical studies. Clinical diagnosis of dementia has been made largely on the basis of clinical findings supported by appropriate radiological and laboratory investigations. A minority of patients have treatable or reversible underlying causes for their dementing syndrome. It is important to distinguish between the two main forms of dementia Alzheimer's disease, senile dementia of Alzheimer type (AD/SDAT) and MID so that advantage can be taken of any future progress in treatments.

    In the clinical study significant differences between several diagnostic procedures were found between patients with AD/SDAT and MID. Blood pressure was significantly lower in the AD/SDAT group and focal neurological signs were seen in 70% of the MID patients but only in 6% of patients with AD/SDAT. Electrocardiogram was normal in all patients with AD/SDAT but pathological in 75% of the MID patients. Electroencephalogram showed generalized slow frequencies in 79% of the AD/SDAT patients and localized changes in 65% of the MID patients. Computerized tomography showed a significantly greater dilation of the ventricular system in MID patients compared to AD/SDAT patients and controls. Monoamine metabolites in the cerebrospinal fluid were lower in AD/SDAT patients and normal in MID patients. Psychopathological signs were found to be more variable and more pronounced in the AD/SDAT group compared with MID patients.

    2. Etiological studies. Immunoglobulin and albumin were found changed in serum and CSF of both AD/SDAT and MID, indicating a more active immune response in MID and a less dense cerebrospinal fluid barrier in both MID and AD/SDAT. There appears to be a consumption of IgG in the central nervous system in patients with AD/SDAT.

    Abnormal chromosomes appearing as acentric fragments, i.e. without visible centromeres, were found in 90% of patients with AD/SDAT, 30% of patients with MID, and not at all in the control group. Increased aneuploidy was also seen both in patients with MID and AD/SDAT.

    Diabetes mellitus in old age and AD/SDAT do not seem to coexist. Furthermore, patients with AD/SDAT have changed carbohydrate metabolism with decreased fasting blood sugar concentrations, increased glucose tolerance and higher concentration of insulin during an oral glucose tolerance test.

    Body Mass Index, Mini Nutritional Assessment, and their Association with Five-Year Mortality in Very Old People2015Inngår i: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 19, nr 4, 461-467 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    OBJECTIVES: to investigate the prevalence of malnutrition and the association between Body Mass Index (BMI), Mini Nutritional Assessment (MNA) and five-year mortality in a representative population of very old (>85 years) people.

    DESIGN: A prospective cohort study.

    SETTING: A population-based study of very old people in northern Sweden and western Finland, living in institutional care or in the community.

    PARTICIPANTS: Out of 1195 potential participants, 832 were included (mean age 90.2±4.6 years).

    MEASUREMENTS: Nutritional status was assessed using BMI and MNA and the association of those two variables with five-year mortality was analyzed.

    RESULTS: The mean BMI value for the whole population was 25.1±4.5 kg/m2, with no difference between genders (P=0.938). The mean MNA score was 22.5±4.6 for the whole sample, and it was lower for women than for men (P<0.001). Thirteen percent were malnourished (MNA<17) and 40.3% at risk of malnutrition (MNA 17-23.5) according to MNA. Also, 34.8% of those with a MNA score <17 still had a BMI value ≥22.2 kg/m2. A BMI value <22.2 kg/m2 and a MNA score<17 were associated with lower survival. The association with mortality seemed to be J-shaped for BMI, and linear for MNA.

    CONCLUSIONS: Malnutrition according to MNA was common, but a substantial portion of those with a low MNA score still had a high BMI value, and vice versa. The association with mortality appeared to be J-shaped for BMI, and linear for MNA. The MNA seems to be a good measurement of malnutrition in very old people, and BMI might be misleading and could underestimate the prevalence of malnutrition, especially in women.

    Anticancer effects of a plant lignan 7-hydroxymatairesinol on a prostate cancer model in vivo.2005Inngår i: Experimental biology and medicine (Maywood, N.J.: Print), ISSN 1535-3702, Vol. 230, nr 3, 217-223 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Clinical intervention studies and experimental studies with lignan-rich diets suggest that lignans may have inhibitory effects on prostate cancer, but no clinical or experimental studies with purified lignans have been published. The purpose of this study was to investigate the effect of a plant lignan 7-hydroxymatairesinol (HMR) on LNCaP human prostate cancer xenografts in athymic mice. Athymic nude male mice were injected subcutaneously with LNCaP cells. Starting 3 days after tumor cell injections, a control diet or a control diet supplemented with 0.15% or 0.30% of HMR was administered to mice and the tumor take rate and growth was observed for 9 weeks. HMR diet inhibited the growth of LNCaP tumors. Mice treated with HMR had smaller tumor volume, lower tumor take rate, increased proportion of nongrowing tumors, and higher tumor cell apoptotic index compared with controls. Furthermore, the cell proliferation index was reduced in mice receiving the 0.30% HMR diet compared with mice receiving the control diet. Our results suggest that dietary HMR started at the early phase of the tumor development inhibits the growth of the LNCaP human prostate cancer xenografts in athymic male mice.

    Nutritional status, body composition and physical activity among older people living in residential care facilities2011Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    The main purpose of this thesis was to study, whether drinkable yoghurt enriched with probiotic bacteria could have any effect on constipation and body weight (BW) among older people with dementia. Further, it concerns poor nutritional status among older people with physical and cognitive impairments and its relationship with factors commonly occur in older people living in residential care facilities. It also discusses how body composition changes with ageing and the associations between changes in muscle mass and functional balance after a high-intensity weight-bearing exercise program (the HIFE program) and the ingestion of an additional milk-based protein-enriched energy supplement.

    A six-month feasibility study that included a probiotic drink was performed among 15 old people who were living in special units for people with dementia and who all had constipation. The effects of the probiotic drink on stool habits, and BW were studied. The outcome measures were followed daily for bowel movements and at three and six months for BW. The staff found the study easy to carry out and that the drink was well accepted by the participants. No convincing beneficial effects on stool habits were observed. In addition, a mean BW loss of 0.65 kg/month was registered. A poor nutritional intake, low physical activity level, and an over-night fast of almost 15 hours, 4 hours longer than recommended were also observed.

    As a part of the FOPANU Study (Frail Older People-Activity and Nutrition Study), a randomized controlled trial was carried out in Umeå - the associations between nutritional status and factors common among old people with physical and cognitive impairments living in residential care facilities was studied. Assessments were made of nutritional status using the Mini Nutritional Assessment (MNA) scale, fat-free mass (FFM) and fat mass (FM) using both bioelectrical impedance spectroscopy (BIS) and skinfold thickness measurements. The effects of a high- intensity functional exercise program with an additional protein-enriched milk drink on ability to build muscle mass were evaluated. Analyses were made to investigate whether nutritional status, assessed using the MNA scale, was associated with medical conditions, drugs, activities of daily living (Barthel ADL index), cognitive impairment (Mini Mental State Examination (MMSE)), and depressive symptoms (Geriatric Depression Scale (GDS)) at baseline. The associations were assessed with multiple linear regression analyses with additional interaction analyses.

    An independent association was found between poor nutritional status and having had a urinary tract infection (UTI) during the preceding year and being dependent in feeding for both women and men, and having lower MMSE scores for women. A large proportion of the participants, were at risk of malnutrition or were already malnourished. Women, but not men, had significantly lower Fat-Free Mass Index (FFMI) and Fat Mass Index (FMI) with age.

    Bioelectrical impedance spectroscopy results correlated with skinfold thickness measurements, but on different levels on value for FM%.

    Despite the high-intensity exercise had long-term effects (at six months, three months after the exercise) on functional balance, walking ability and leg strength. No effects on muscle mass and no additional effects from the protein-enriched drink could be observed after the three months of high intensity exercise. A negative, long-term effect on the amount of muscle mass and BW was revealed at six months (three months after the intervention had ended). The effects from the exercise did not differ for participants who were malnourished. No statistical interactions were observed between sex, depression, dementia disorder, and nutritional status, and the level of functional balance capacity on the outcome at three or six months.

    In summary, the majority of the included older people with dementia had a low dietary intake, low physical activity level, and lost BW despite receiving a probiotic drink supplement every day for six months. The supplementation had no detectable effect on constipation. Among the participants in the FOPANU Study, UTI during the preceding year was independently associated with poor nutritional status. Being dependent in feeding was associated with poor nutritional status as were lower MMSE scores for women but not for men. Despite the high-intensity exercise program had long-term effects on the fysical function was no effect on the amount of muscle mass at three months observed. The FFM and FM expressed as indexes of body height were inversely related to age for women, but not for men. A high-intensity exercise program did not have any effect on the amount of muscle mass. The ingestion of a protein-enriched drink immediately after exercise produced no additional effect on the outcome and the results did not differ for participants who were malnourished. The negative long-term effect on amount of muscle mass, and BW, indicate that it is necessary to compensate for increased energy demands during a high-intensity exercise program. High age, female sex, depression, mild to moderate dementia syndrome, malnutrition, and severe physical impairment do not seem to have a negative impact on the effect of a high-intensity functional weight-bearing exercise program. Consequently, people with these characteristics in residential care facilities should not be excluded from training and rehabilitation including nutrition. More research is needed in large randomized controlled trials to further explore the association between energy balance and malnutrition among frail old people, with a special focus on UTI and constipation, but also to study how physical exercise affects older people’s nutritional status.

    Body composition in Swedish old people aged 65-99 years, living in residential care facilities2009Inngår i: Archives of gerontology and geriatrics (Print), ISSN 0167-4943, E-ISSN 1872-6976, Vol. 49, nr 1, 98-107 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    It is important to evaluate body composition changes in subjects with an existing multi-system reduction in capacity, as a small decrease in fat-free mass (FFM) can cause serious impairments. The aim of the study was to describe body composition in old people living in institutions. Body composition data were collected within a study of 173 subjects with functional and cognitive impairment, aged 65-99 years, and living in residential care facilities. A bioelectrical impedance spectrometer (BIS) (Xitron Hydra 4200; 5-1000 kHz) was used to assess the amount of both FFM and fat mass (FM) which where adjusted for height. The Harpenden caliper and a tape measure were used to assess body fat, arm-muscle and arm-fat area (mm(2)). A large proportion of the old and functionally impaired population was at risk of malnutrition or already malnourished (63.4% vs. 17.4%) according to Mini-Nutritional Assessment (MNA). Women had significantly lower fat-free mass index (FFMI) and higher FMI, inversely related to age, than men. Bioelectrical impedance spectroscopy and anthropometrical measurements correlated but on different levels. In addition the FM% differed between the two methods (46.3% vs. 33.4%).

    The feasibility of serving liquid yoghurt supplemented with probiotic bacteria, Lactobacillus rhamnosus LB 21, and Lactococcus lactis L1A: a pilot study among old people with dementia in a residential care facility2009Inngår i: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 13, nr 9, 813-819 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background: Constipation and body weight loss are prevalent among old people. Treatment with different species of lactic acid bacteria has been suggested for various forms of gastrointestinal disorders.

    Objective, participants and intervention: This pilot study was performed to assess the feasibility of administering and consuming a drinkable yoghurt containing Lactobacillus rhamnosus LB 21 and Lactococcus L1A, and to evaluate the influence on bowel movements and body weight in 15 people with dementia, aged 65–95 years in residential care facility.

    Design: A drinkable yoghurt (Verum Drickyoghurt©) with added bacteria was served daily for 6 months in conjunction with ordinary food intake. Body weight, bowel movement frequency and consistency, food and fluid intake and time spent in various activities were recorded for two weeks preintervention, and 3 times during the follow-up period.

    Result: This study showed that the yoghurt was easy to serve, with few side effects for the participants and that the various recording forms and diaries were easy for the staff to complete. The extra intake of yoghurt did not have any detectable beneficial effect on bowel movements. The overnight fast was almost 15 hours per day. Body weight decreased by 0.65 kg/month (95% confidence interval. 0.27–0.97).

    Conclusions: The present study design was feasible in this group of old people with dementia. The absence of any detectable effect of the supplement on constipation, but rather a considerable loss in body weight, indicate that further research is needed in a large randomised controlled trial, if associations between dementia, constipation and energy balance are to be understood.

    Poor nutritional status is associated with urinary tract infection among older people living in residential care facilities2013Inngår i: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 17, nr 2, 186-191 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    To investigate factors associated with poor nutritional status in older people living in residential care facilities. Methods: 188 residents (136 women, 52 men) with physical and cognitive impairments participated. Mean age was 84.7 y (range 65-100). The Mini Nutritional Assessment (MNA), Barthel ADL Index, Mini Mental State Examination (MMSE), and Geriatric Depression Scale were used to evaluate nutritional status, activities of daily living, cognitive status and depressive symptoms. Medical conditions, clinical characteristics and prescribed drugs were recorded. Univariate and multivariate regressions were used to investigate associations with MNA scores. Results: The mean MNA score was 20.5 +/- 3.7 (range 5.5-27) and the median was 21 (interquartile range (IQR) 18.8-23.0). Fifteen per cent of participants were classified as malnourished and 66% at risk of malnutrition. Lower MNA scores were independently associated with urinary tract infection (UTI) during the preceding year (beta = -0.21, P = 0.006), lower MMSE scores (beta = 0.16, P = 0.030), and dependent in feeding (beta = -0.14, P = 0.040). Conclusion: The majority of participants were at risk of or suffering from malnutrition. Urinary tract infection during the preceding year was independently associated with poor nutritional status. Dependence in feeding was also associated with poor nutritional status as were low MMSE scores for women. Prospective observations and randomized controlled trials are necessary to gain an understanding of a causal association between malnutrition and UTI.

    Effects of high-intensity exercise and protein supplement on muscle mass in ADL dependent older people with and without malnutrition: a randomized controlled trial2011Inngår i: The Journal of Nutrition, Health & Aging, ISSN 1279-7707, E-ISSN 1760-4788, Vol. 15, nr 7, 554-560 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Background  Loss of muscle mass is common among old people living in institutions but trials that evaluate interventions aimed at increasing the muscle mass are lacking.

    Objective, participants and intervention  This randomized controlled trial was performed to evaluate the effect of a high-intensity functional exercise program and a timed protein-enriched drink on muscle mass in 177 people aged 65 to 99 with severe physical or cognitive impairments, and living in residential care facilities.

    Design  Three-month high-intensity exercise was compared with a control activity and a protein-enriched drink was compared with a placebo drink. A bioelectrical impedance spectrometer (BIS) was used in the evaluation. The amount of muscle mass and body weight (BW) were followed-up at three and six months and analyzed in a 2 × 2 factorial ANCOVA, using the intention to treat principle, and controlling for baseline values.

    Results  At 3-month follow-up there were no differences in muscle mass and BW between the exercise and the control group or between the protein and the placebo group. No interaction effects were seen between the exercise and nutritional intervention. Long-term negative effects on muscle mass and BW was seen in the exercise group at the 6-month follow-up.

    Conclusion  A three month high-intensity functional exercise program did not increase the amount of muscle mass and an intake of a protein-enriched drink immediately after the exercise did not induce any additional effect on muscle mass. There were negative long-term effects on muscle mass and BW, indicating that it is probably necessary to compensate for an increased energy demand when offering a high-intensity exercise program.

    Delirium in older people after cardiac surgery: risk factors, dementia, patients’ experiences and assessments2016Doktoravhandling, med artikler (Annet vitenskapelig)
    Abstract [en]

    Background:

    Delirium is common in older people undergoing cardiac surgery. Delirium is an acute or subacute neuro-psychiatric syndrome, characterized by a change in cognition, disturbances in consciousness; it fluctuates, develops over a short period of time and always has an underlying cause. It is associated with a disturbance in psychomotor activity, and is classified according to different clinical profiles such as hypoactive, hyperactive and mixed delirium. Delirium after cardiac surgery is not harmless, it increases the risk of complications such as prolonged stay in hospital, falls, reduced quality of life, reduced cognitive function and increased mortality.

    Aim:

    The overall aim of this thesis was to investigate postoperative delirium in older people undergoing cardiac surgery with Cardiopulmonary Bypass (CPB), focusing on risk factors, dementia and patients’ experiences; and to evaluate an assessment for screening delirium.

    Methods:

    This thesis compromises four studies. All participants (n=142) were scheduled for cardiac surgery with use of CPB at the Cardiothoracic Surgery Department, Heart Centre, Umeå University Hospital, Sweden, between February and October 2009. Six structured interviews were conducted preoperatively, day one and day four postoperatively, and in home visits, one, three and five years after surgery (2010, 2012 and 2014). The assessment scales used in Studies I, II and IV were: the Mini-Mental State Examination (MMSE) for cognition, the Organic Brain Syndrome Scale (OBS) for delirium, Geriatric Depression Scale 15 (GDS-15) for depression, Katz staircase with Activities of Daily Living (ADL) for participants’ functional status and the Numerical Rating Scale (NRS) for pain. During the hospital stay, nursing staff used the Swedish version of the Nursing Delirium Screening Scale (Nu-DESC) to assess delirium. Semi-structured interviews were also carried out (III) in the one-year follow up. Delirium, dementia and depression were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders (DSM IV TR).

    Results:

    Out of 142 participants 54.9% (78/142) developed delirium after cardiac surgery (I). Independent risk factors, predisposing and precipitating, associated with delirium were: age, diabetes, gastritis/peptic ulcer, volume load during operation, longer time on ventilator in intensive care, increased temperature and plasma sodium concentration in the intensive care unit. Out of 114 participants thirty (26.3%) developed dementia within the five years of follow-up. It was shown that a lower preoperative MMSE score and postoperative delirium were factors independently associated with development of dementia (II). One year after cardiac surgery, participants diagnosed with postoperative delirium described in detail feelings of extreme vulnerability and frailty. Despite this, the participants were grateful for the care they had received (III). Hypoactive was the most common symptom profile for delirium. The Swedish version of Nu-DESC showed high sensitivity in detecting hyperactive delirium, but low sensitivity in detecting hypoactive delirium (IV).

    Conclusion:

    Delirium was common among older patients undergoing cardiac surgery. Both predisposing and precipitating factors contributed to postoperative delirium. Preventive strategies should be considered in future randomized studies. It might also be suggested that cognitive function should be screened for preoperatively and patients who develop delirium should be followed up to enable early detection of symptoms of dementia. Whether prevention of postoperative delirium can reduce the risk of future dementia remains to be studied. To minimise unnecessary suffering, patients and next of kin should be informed about and prepared for the risk of delirium developing during hospitalization. The Swedish version of Nu-DESC should be combined with cognitive testing to improve detection of hypoactive delirium, but further research is needed. Healthcare professionals need knowledge concerning postoperative delirium in order to prevent, detect and treat delirium so as to avoid and relieve the suffering it might cause.

    Validation of the Swedish version of the Nursing Delirium Screening Scale used in patients 70 years and older undergoing cardiac surgery2013Inngår i: Journal of Clinical Nursing, ISSN 0962-1067, E-ISSN 1365-2702, Vol. 22, nr 19-20, 2858-2866 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    AIMS AND OBJECTIVES: Validation of the Swedish version of the Nursing Delirium Screening Scale as a screening tool for nurses to use to detect postoperative delirium in patients 70 years and older undergoing cardiac surgery.

    BACKGROUND: Delirium is common among old patients after cardiac surgery. Underdiagnosis and poor documentation of postoperative delirium is problematic, and nurses often misread the signs.

    DESIGN: A prospective observational study.

    METHODS: Patients (n = 142) scheduled for cardiac surgery were assessed three times daily by the nursing staff using the Nursing Delirium Screening Scale. Nursing Delirium Screening Scale was compared with the Mini Mental State Examination and the Organic Brains Syndrome Scale, evaluated day one and day four postoperatively. Delirium was diagnosed according to Diagnostic and Statistical Manual of Mental Disorders - DSM-IV-TR criteria.

    RESULTS: A larger proportion of patients were diagnosed with delirium according to the Mini Mental State Examination and Organic Brains Syndrome Scale compared with the Nursing Delirium Screening Scale, both on day one and day four. The Nursing Delirium Screening Scale protocol identified the majority of hyperactive and mixed delirium patients, whereas several with hypoactive delirium were unrecognised.

    CONCLUSIONS: The Swedish version of the Nursing Delirium Screening Scale was easily incorporated into clinical care and showed high sensitivity in detecting hyperactive symptoms of delirium. However, in the routine use by nurses, the Nursing Delirium Screening Scale had low sensitivity in detecting hypoactive delirium, the most prevalent form of delirium after cardiac surgery. Nursing Delirium Screening Scale probably has to be combined with cognitive testing to detect hypoactive delirium.

    RELEVANCE TO CLINICAL PRACTICE: Nurses play a key role in detecting delirium. The Nursing Delirium Screening Scale was easy incorporated instrument for clinical practice and identified the majority of hyperactive and mixed delirium, but several of the patients with hypoactive delirium were unrecognised. Training of assessment and cognitive testing seems to be necessary to detect hypoactive delirium.

    Preoperative Cognitive Performance and Postoperative Delirium Are independently Associated With Future Dementia in Older People Who Have Undergone Cardiac Surgery: A Longitudinal Cohort Study2017Inngår i: Critical Care Medicine, ISSN 0090-3493, E-ISSN 1530-0293, Vol. 45, nr 8, 1295-1303 s.Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Objective: To investigate if postoperative delirium was associated with the development of dementia within 5 years after cardiac surgery.

    Design: Longitudinal cohort study.

    Setting: Cardiothoracic Division, Umeå University Hospital, Sweden.

    Patients: Patients aged 70 years old or older (n = 114) scheduled for routine cardiac procedures with cardiopulmonary bypass without documented dementia were enrolled in 2009.

    Intervention: Structured assessments were performed preoperatively, 1 and 4 days after extubation, and 1, 3, and 5 years postoperatively.

    Measurements and Main Results: Patients were assessed comprehensively, including cognitive and physical function, coexisting medical conditions, demographic characteristics, and medications. Diagnoses of delirium, depression, and dementia were made according to Diagnostic and Statistical Manual of Mental Disorders, 4th Edition, Text Revision criteria. During the 5-year period, 30 of 114 participants (26.3%) developed dementia. Postoperative delirium had occurred in 87% of those who later developed dementia. A multivariable logistic regression model showed a lower preoperative Mini-Mental State Examination score (p < 0.001; odds ratio, 0.68; 95% CI, 0.54–0.84) and the occurrence of postoperative delirium (p = 0.002; odds ratio, 7.57; 95% CI, 2.15–26.65) were associated with dementia occurrence.

    Conclusions: Our findings suggest that older patients with reduced preoperative cognitive functions or who develop postoperative delirium are at risk of developing dementia within 5 years after cardiac surgery. Cognitive functions should be screened for preoperatively, those who develop postoperative delirium should be followed up to enable early detection of dementia symptoms, and management should be implemented.
