IMPORTANCE: Treatment with antidepressants has been associated with hip fracture. This association could restrict the treatment options, especially in older patients. OBJECTIVE: To investigate the association between antidepressant drug treatment and hip fracture starting 1 year before the initiation of treatment. DESIGN, SETTING, AND PARTICIPANTS: In this nationwide cohort study, 204 072 individuals in the Prescribed Drugs Register of Sweden's National Board of Health and Welfare aged 65 years or older who had a prescription of antidepressants filled between July 1, 2006, and December 31, 2011, were matched by birth year and sex to 1 control participant who was not prescribed antidepressants (for a total of 408 144 people in the register). Outcome data were collected from 1 year before to 1 year after the index date (date of prescription being filled). Data analysis was performed from July 1, 2005, to December 31, 2012. EXPOSURES: First filled prescription of an antidepressant drug. MAIN OUTCOMES AND MEASURES: Incident hip fractures occurring in the year before and year after initiation of antidepressant therapy were registered. Associations were investigated using multivariable conditional logistic regression models and flexible parametric models. RESULTS: Of the 408 144 people in the register who were included in the study, 257 486 (63.1%) were women, with a mean (SD) age of 80.1 (7.2) years. Antidepressant users sustained more than twice as many hip fractures than did nonusers in the year before and year after the initiation of therapy (2.8% vs 1.1% and 3.5% vs 1.3%, respectively, per actual incidence figures). In adjusted analyses, the odds ratios were highest for the associations between antidepressant use and hip fracture 16 to 30 days before the prescription was filled (odds ratio, 5.76; 95% CI, 4.73-7.01). In all separate analyses of age groups, of men and women, and of individual antidepressants, the highest odds ratios were seen 16 to 30 days before initiation of treatment, and no clear dose-response relationship was seen. CONCLUSIONS AND RELEVANCE: The present study found an association between antidepressant drug use and hip fracture before and after the initiation of therapy. This finding raises questions about the association that should be further investigated in treatment studies.

Background: Constipation is a common condition among older people, particularly among people living in nursing homes, and the use of drugs such as opioids is one of many factors that contribute to its high prevalence. The aim of this study was to compare the prevalence of constipation and the use of laxatives between 2007 and 2013, to analyze constipation and laxative use among people who are prescribed opioids, and to identify factors associated with constipation. Methods: In 2007 and 2013, two surveys were performed in the county of Vasterbotten in Northern Sweden, comprising all those living in nursing homes. The Multi-Dimensional Dementia Assessment Scale was used to collect data regarding laxative, opioid and anticholinergic drug use, functioning in activities of daily living (ADL), cognition and symptoms of constipation. A comparison was made between 2820 people from 2007 and 1902 people from 2013. Results: The prevalence of symptoms of constipation among people living in nursing homes increased from 36% in 2007 to 40% in 2013. After controlling for age, sex, ADL, cognitive impairment and use of opioid and anticholinergic drugs, this difference was found to be statistically significant. When controlled for demographic changes, there was a statistically significant difference in the regular use of laxatives between the respective years, from 46% in 2007 to 59% in 2013. People prescribed opioids and anticholinergic drugs were at increased risk of constipation, while people with a higher ADL score were at decreased risk. Further, among people prescribed opioids and rated as constipated, 35% in 2007 and 20% in 2013 were not prescribed laxatives for regular use, a difference that was found to be statistically significant. Conclusions: The prevalence of symptoms of constipation increased between 2007 and 2013. Although there was a decrease between the years, there were still a number of people being prescribed with opioids and rated as constipated who were not treated with laxatives. This study therefore indicates that constipation remains a significant problem among people in nursing homes and also indicates that those prescribed opioids could benefit from an increased awareness of the risk of constipation and treatment, if required.

OBJECTIVES: The objectives were to study changes in morale in individuals 85 years and older, and to assess the effect of negative life events on morale over a five-year follow-up period.

METHOD: The present study is based on longitudinal data from the Umeå85+/GERDA-study, including individuals 85 years and older at baseline (n = 204). Morale was measured with the Philadelphia Geriatric Center Morale Scale (PGCMS). Negative life events were assessed using an index including 13 negative life events occurring during the follow-up period. Linear regression was used for the multivariate analyses.

RESULTS: The majority of the sample (69.1%) had no significant changes in morale during the five-year follow-up. However, the accumulation of negative life events was significantly associated with a greater decrease in PGCMS. A higher baseline PGCMS score did not attenuate the adverse effect negative life events had on morale.

CONCLUSION: Morale seemed to be mainly stable in a five-year follow-up of very old people. It seems, nonetheless, that individuals are affected by negative life events, regardless of level of morale. Preventing negative life events and supporting individuals who experience multiple negative life events could have important implications for the care of very old people.

Background: Herpes simplex virus (HSV) has been suggested to play a role in Alzheimer’s disease (AD) development.

Objective: The aim of the present study was to investigate the early AD-related symptom episodic memory decline in relation to HSV and carriage of allele 4 of the apolipoprotein E gene (APOE ɛ4) in a large population-based cohort with a long follow-up time.

Methods: The study included 3,413 persons, with longitudinal data available for 1,293 persons with a mean follow-up time of 11.6 years. The associations between HSV carriage, APOE ɛ4 carriage, and episodic memory was investigated at baseline, as well as in longitudinal analyses where individuals with and without HSV antibodies (HSV1/2 non-specific) were matched and episodic memory decline compared.

Results: Cross-sectional analyses revealed an age-dependent association of HSV carriage with lower episodic memory function, particularly among APOE ɛ4 carriers (p = 0.008). Longitudinal analyses showed an increased risk of episodic memory decline in HSV carriers (≥65 years: p < 0.001, all ages: non-significant), and a significant interaction between HSV and APOE ɛ4 for episodic memory decline (p < 0.001).

Conclusion: In this large population-based cohort study, both cross-sectional and longitudinal results support an association between HSV carriage and declining episodic memory function, especially among APOE ɛ4 carriers. The results strengthen the hypothesis that HSV is associated with AD development.

BACKGROUND: Clinical pharmacists play an increasing role in the pharmacological treatment of hospital-admitted older patients with dementia or cognitive impairment. In an earlier randomised controlled trial, clinical pharmacist involvement in the ward team could significantly reduce drug-related readmissions in patient subgroups. However, the economic impact of the intervention has not been addressed so far.

OBJECTIVES: To evaluate the economic impact of clinical pharmacist engagement in hospital ward teams for medication therapy management in older patients with dementia or cognitive impairments.

METHODS: Economic evaluation of a randomised controlled trial conducted in two hospitals in Northern Sweden between January 2012 and December 2014. Participants included 460 hospital-admitted older patients with dementia or cognitive impairments. Patients were randomly assigned to usual care, or usual care with pharmacist intervention; the intervention consisted of medication reconciliation, medication review, and participation in ward rounds. The outcomes were measured as drug-related readmissions to hospital as assessed by a group of external experts, 180 and 30 days after discharge. Costs included pharmacists' direct labour costs for the interventions, average costs for drug-related readmissions, and from this the total cost per person was calculated.

RESULTS: The effect of the intervention on drug-related readmissions within 180 days was significant in patients without heart failure (subgroup analysis), and the intervention resulted in cost savings of €950 per person in this subgroup. Drug-related readmissions within 30 days were reduced in the total sample (post-hoc analysis), and the cost-savings in this intervention group were €460 per person.

CONCLUSIONS: Post-hoc and subgroup analyses indicate that engagement of pharmacists in hospital ward teams reduced the number of drug-related readmissions, and that the cost per person was lower in the intervention group compared to the control group. Including clinical pharmacists created savings in the subgroups of older patients with dementia or cognitive impairments.

Sheltered housing is a housing model that provides accessible apartments with elevated social possibilities for older people, which is expected to increase resident health and independence, reducing the need for care. As previous research on sheltered housing is scarce, the aim of this study was to explore the characteristics, health status and social participation of older people living in sheltered housing, compared to ageing in place. The study utilised baseline data from a matched cohort study survey on a nationally representative total population of residents in all sheltered housings in Sweden, and a matched control group (n = 3,805). The data collection took place between October 2016 and January 2017. The survey assessed functional capability using the Katz ADL and Lawton IADL scale, self-rated health using the EQ5D scale, and depressive mood using the GDS-4 scale. Descriptive statistics, frequencies, mean scores, independent t tests, p-values and effect sizes were utilised to compare the two groups. The results of the study show that older people living in sheltered housing, compared to ageing in place, had lower self-reported health (M = 64.68/70.08, p = <0.001), lower self-reported quality of life (M = 0.73/0.81, p = <0.001), lower functional status concerning activities of daily living (M = 5.19/5.40, p = <0.001), lower functional status concerning instrumental activities of daily living (M = 4.98/5.42 p = <0.001,), and higher probability of depressive mood (M = 0.80/0.58, p = <0.001). The results imply that residents in sheltered housing may have more care needs than those ageing in place. Further longitudinal comparative studies are needed to explore the impact residence in sheltered housing has on resident health and well-being.

High morale could be considered to be an essential part of aging well and increased knowledge of how to prevent a decreasein high morale in very old age could have important implications for policy, and social and health care development. Theobjective was to identify social and health-related risk factors for a decrease in morale over 5 years in very old peopleamong those with high morale at baseline. The study is based on data derived from the Umeå85+/GERDA study conductedin Northern Sweden and Western Finland. The final sample consisted of 174 individuals who were 85 years and older atbaseline and who had completed the follow-up 5 years later. Morale was measured with The Philadelphia Geriatric CenterMorale Scale (PGCMS). A set of social and health-related variables were used to test which factors were associated with adecrease in morale over 5 years. Linear regression was used for the multivariable analyses. The sample had a mean changeof − 1.3 (SD = 2.5) in PGCMS scores from T1 to T2. The results from the regression analyses showed that development ofdepressive disorders, increased feelings of loneliness and the death of a child during the follow-up period were associatedwith a decrease in morale. The results from our study indicate that preventing the development of depressive disorders andincreasing loneliness are key factors in preventing a decrease in high morale. Additionally, very old people who have recentlylost an adult child should receive adequate psychosocial support

Aim: To evaluate the psychometric properties and performance of the 32‐item Thriving of Older People Assessment Scale (TOPAS) and to explore reduction into a short‐form.

Background: The 32‐item TOPAS has been used in studies of place‐related well‐being as a positive measure in long‐term care to assess nursing home resident thriving; however, item redundancy has not previously been explored.

Design: Cross‐sectional.

Method: Staff members completed the 32‐item TOPAS as proxy‐raters for a random sample of Swedish nursing home residents (N = 4,831) between November 2013 and September 2014. Reliability analysis, exploratory factor analysis and item response theory‐based analysis were undertaken. Items were systematically identified for reduction using statistical and theoretical analysis. Correlation testing, means comparison and model fit evaluation confirmed scale equivalence.

Results: Psychometric properties of the 32‐item TOPAS were satisfactory and several items were identified for scale reduction. The proposed short‐form TOPAS exhibited a high level of internal consistency (α=0.90) and strong correlation (r=0.98) to the original scale, while also retaining diversity among items in terms of factor structure and item difficulties.

Conclusion: The 32‐item and short‐form TOPAS' indicated sound validity and reliability to measure resident thriving in the nursing home context.

Impact: There is a lack of positive life‐world measures for use in nursing homes. The short‐form TOPAS indicated sound validity and reliability to measure resident thriving, providing a feasible measure with enhanced functionality for use in aged care research, assessments and care planning for health promoting purposes in nursing homes.

Herpes simplex virus type 1 (HSV1), establishes life-long latency and can cause symptoms during both first-time infection and later reactivation. The aim of the present study was to describe a protocol to generate a reliable and discriminative avidity index (AI) for anti-HSV1 IgG content in human sera. Human serum from two distinct cohorts; one a biobank collection (Betula) (n = 28), and one from a clinical diagnostics laboratory at Northern Sweden University Hospital (NUS) (n = 18), were assessed for presence of IgG antibodies against HSV1 by a commercially available ELISA-kit. Addition of urea at the incubation step reduces effective binding, and the ratio between urea treated sample and non-treated sample was used to express an avidity index (AI) for individual samples. AI score ranged between 43.2 and 73.4% among anti-HSV1 positive biobank sera. Clinical samples ranged between 36.3 and 74.9%. Reproducibility expressed as an intraclass correlation coefficient (ICC) was estimated at 0.948 (95% CI: 0.900-0.979) and 0.989 (95% CI 0.969-0.996) in the biobank and clinical samples, respectively. The method allows for AI scoring of anti-HSV1 IgG from individual human sera with a single measurement. The least significant change between two measurements at the p < 0.05 level was estimated at 5.4 and 3.2 points, respectively, for the two assessed cohorts.
