ObjectivesTo investigate the effects of a high-intensity functional exercise program on independence in activities of daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types.DesignCluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study.SettingResidential care facilities, Umeå, Sweden.ParticipantsIndividuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N = 186).InterventionNinety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity.MeasurementsBlinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months.ResultsLinear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=−1.6–4.3; BI=0.6, 95% CI=−0.2–1.4) or 7 (FIM=0.8, 95% CI=−2.2–3.8; BI=0.6, 95% CI=−0.3–1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8–6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months.ConclusionIn older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.
Background:Although physical exercise has been suggested to influence cognitive function, previous exercise studies show inconsistent results in people with dementia.Objectives:To investigate effects of exercise on cognitive function in people with dementia.Method:The Umeå Dementia and Exercise (UMDEX) study, a cluster-randomized controlled trial, was set in 16 nursing homes in Umeå, Sweden. One hundred-and-forty-one women and 45 men with dementia; mean age of 85 y and mean Mini-Mental State Examination (MMSE) score of 15, were randomized to a High-Intensity Functional Exercise program or a seated attention control activity. Blinded assessors measured global cognitive function using the MMSE and the Alzheimer’s disease Assessment Scale – Cognitive subscale (ADAS-Cog), and executive function using Verbal fluency (VF) at baseline and 4 months (directly after intervention completion), and MMSE and VF at 7 months.Results:Linear mixed models showed no between-group effects in mean difference from baseline (95% confidence intervals, CI) at 4 months in MMSE (–0.27; 95% CI –1.4 to 0.87, p = 0.644), ADAS-Cog (–1.04, 95% CI –4 to 1.92, p = 0.491), or VF (–0.53, 95% CI –1.42 to 0.35, p = 0.241) or at 7 months in MMSE (–1.15, 95% CI –2.32 to 0.03, p = 0.056) or VF (–0.18, 95% CI –1.09 to 0.74, p = 0.707).Conclusion:A 4-month, high-intensity functional exercise program had no superior effects on global cognition or executive function in people with dementia living in nursing homes when compared with an attention control activity.
SummaryKnowledge of risk factors for hip fracture among very old people is limited. Walking indoors with help from ≤1 person, Parkinson’s disease, currently smoking, delirium in the previous month, underweight, and age were associated with increased risk of hip fracture and could be important for preventive strategy development.IntroductionThe purpose of this study is to investigate risk factors for hip fracture among a representative sample of very old people.MethodsIn total, 953 participants from the Umeå 85+/Gerontological Regional Database population-based cohort study were interviewed and assessed during home visits. Associations of baseline characteristics with hip fracture during the maximum 5-year follow-up period were analyzed using Cox proportional hazards regression.ResultsParticipants had a mean age of 89.3 ± 4.7 years; 65.8 % were women, 36.8 % lived in residential care facilities, 33.6 % had dementia, and 20.4 % had histories of hip fracture. During a mean follow-up period of 2.7 years, 96 (10.1 %) individuals sustained hip fracture. Walking indoors with help from no more than one person (hazard ratio [HR] = 8.57; 95 % confidence interval [CI], 1.90–38.71), Parkinson’s disease (HR = 5.12; 95 % CI, 1.82–14.44), currently smoking (HR = 4.38; 95 % CI 2.06–9.33), delirium in the previous month (HR = 2.01; 95 % CI, 1.15–3.49), underweight (body mass index <22; HR = 1.74, 95 % CI, 1.09–2.77), and age (HR = 1.09; 95 % CI, 1.04–1.14) were associated independently with an increased risk of hip fracture. Hip prosthesis at baseline decreased the risk of hip fracture (HR = 0.37; 95 % CI, 0.15–0.91), but only for those with bilateral hip prostheses.ConclusionsSeven factors were associated independently with incident hip fracture during follow-up in this sample of very old people. These factors could have important clinical implications in identifying persons at high risk of hip fracture, as well as in the development of effective preventive strategies.
In people with dementia living in nursing homes exercise had positive effects on gait when tested unsupported compared with when walking aids or minimum support was used. The study suggests that the use of walking aids in gait speed tests may conceal exercise effects.
Background Nephrotic syndrome (NS) is associated with increased risk of venous thromboembolism (VTE). Guidelines suggest prophylactic anticoagulants to patients with high risk of thrombosis and low risk of bleeding, but the evidence behind this is poor. This study aims to investigate the effectiveness and risks of prophylactic anticoagulants (PAC) and investigate risk factors for VTE and bleeding in NS. Methods A retrospective medical records study including adults with NS, biopsy proven glomerular disease in the county of Västernorrland, Sweden. Outcomes were VTE, bleeding and death. Patients divided into PAC- and no PAC group were compared using Fisher’s exact test. Patient time was divided into serum/plasma(S/P)-albumin intervals (<20g/L and ≥20g/L) and VTE- and bleeding rates were calculated. Results In 95 included NS patients (PAC = 40, no PAC = 55), 7 VTE (7.4%) and 17 bleedings (18%) were found. Outcomes didn’t differ significantly between the PAC and no PAC group. Time with S/P-albumin <20g/L conferred higher rates/100 years of VTE (IRR 21.7 (95%CI 4.5–116.5)) and bleeding (IRR 5.0 (1.4–14.7)), compared to time with S/P-albumin>20g/L. Conclusion Duration of severe hypoalbuminemia (S/P-albumin <20g/L) in NS is a risk factor for both VTE and bleeding. There is a need for randomized controlled studies regarding the benefit of PAC in NS as well as risk factors of thrombosis and bleeding in NS.
Background:The effectiveness of different procedures in routine surgical practice for hernia repair with respect to chronic postoperative pain and reoperation rates is not clear. Conclusion:The risk of significant pain 1 year after groin hernia repair in routine surgical practice was 15⋅2 per cent. This figure was lower in patients who had surgery by an endoscopic technique, but at the price of a significantly higher risk of reoperation for recurrence.
ObjectivesThe 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.MethodsResidents (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.ResultsNo 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).ConclusionsA 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.
