Decreased glomerular filtration rate (GFR) and albuminuria may be accompanied by brain pathology. Here we investigated whether changes in these kidney measures are linked to development of new MRI-detected infarcts and microbleeds, and progression of white matter hyperintensity volume. The study included 2671 participants from the population-based AGES-Reykjavik Study (mean age 75, 58.7% women). GFR was estimated from serum creatinine, and albuminuria was assessed by urinary albumin-to-creatinine ratio. Brain MRI was acquired at baseline (2002-2006) and 5 years later (2007-2011). New MRI-detected infarcts and microbleeds were counted on the follow-up scans. White matter hyperintensity progression was estimated as percent change in white matter hyperintensity volumes between the two exams. Participants with a large eGFR decline (over 3 ml/min/1.73m2 per year) had more incident subcortical infarcts (odds ratio 1.53; 95% confidence interval 1.05, 2.22), and more marked progression of white matter hyperintensity volume (difference: 8%; 95% confidence interval: 4%, 12%), compared to participants without a large decline. Participants with incident albuminuria (over 30 mg/g) had 21% more white matter hyperintensity volume progression (95% confidence interval: 14%, 29%) and 1.86 higher odds of developing new deep microbleeds (95% confidence interval 1.16, 2.98), compared to participants without incident albuminuria. The findings were independent of cardiovascular risk factors. Changes in kidney measures were not associated with occurrence of cortical infarcts. Thus, larger changes in eGFR and albuminuria are associated with increased risk for developing manifestations of cerebral small vessel disease. Individuals with larger changes in these kidney measures should be considered as a high risk population for accelerated brain pathology.
Anticholinergic drug use has been associated with a risk of central and peripheral adverse effects. There is a lack of information on anticholinergic drug use in persons with diabetes. The aim of this study is to investigate anticholinergic drug use and the association between anticholinergic drug use and self-reported symptoms in older community-dwelling persons with and without diabetes.
The basic population was comprised of Finnish community-dwelling primary care patients aged 65 and older. Persons with diabetes were identified according to the ICD-10 diagnostic codes from electronic patient records. Two controls adjusted by age and gender were selected for each person with diabetes. This cross-sectional study was based on electronic primary care patient records and a structured health questionnaire. The health questionnaire was returned by 430 (81.6%) persons with diabetes and 654 (73.5%) persons without diabetes. Data on prescribed drugs were obtained from the electronic patient records. Anticholinergic drug use was measured according to the Anticholinergic Risk Scale. The presence and strength of anticholinergic symptoms were asked in the health questionnaire.
The prevalence of anticholinergic drug use was 8.9% in the total study cohort. There were no significant differences in anticholinergic drug use between persons with and without diabetes. There was no consistent association between anticholinergic drug use and self-reported symptoms.
There is no difference in anticholinergic drug use in older community-dwelling persons with and without diabetes. Anticholinergic drug use should be considered individually and monitored carefully.
In Iceland, there is a large variation in daylight between summer and winter. The aim of the study was to identify how this large variation influences physical activity (PA) and sedentary behavior (SB). Free living PA was measured by a waist-worn accelerometer for one week during waking hours in 138 community-dwelling older adults (61.1% women, 80.3 ± 4.9 years) during summer and winter months. In general, SB occupied about 75% of the registered wear-time and was highly correlated with age (ß = 0.36). Although the differences were small, more time was spent during the summer in all PA categories, except for the moderate-to-vigorous PA (MVPA), and SB was reduced. More lifestyle PA (LSPA) was accumulated in =5-min bouts during summer than winter, especially among highly active participants. This information could be important for policy makers and health professionals working with older adults. Accounting for seasonal difference is necessary in analyzing SB and PA data.

Effects of 12-month home-based physiotherapy on duration of living at home and functional capacity among older persons with signs of frailty or with a recent hip fracture - protocol of a randomized controlled trial (HIPFRA study).
Health concerns, such as frailty and osteoporotic fractures decrease functional capacity and increase use of health and social care services in the aging population. The ability to continue living at home is dependent on functional capacity, which can be enhanced by rehabilitation. We study the effects of a 12-month home-based physiotherapy program with 12-month follow-up on duration of living at home, functional capacity, and the use of social and health care services among older persons with signs of frailty, or with a recently operated hip fracture.
This is a non-blinded, parallel group, randomized controlled trial performed in South Karelia Social and Health Care District, Finland (population 131,000). Three hundred community-dwelling older persons with signs of frailty (age?=?65) and 300 persons with a recent hip fracture (age?=?60) will be recruited. Frailty is screened by FRAIL questionnaire and verified by modified Fried's frailty criteria. Both patient groups will be randomized separately to a physiotherapy and a usual care arm. Individualized, structured and progressive physiotherapy will be carried out for 60 min, twice a week for 12 months at the participant's home. The primary outcome at 24 months is duration of living at home. Our hypothesis is that persons assigned to the physiotherapy arm will live at home for six months longer than those in the usual care arm. Secondary outcomes are functional capacity, frailty status, health-related quality-of-life, falls, use and costs of social and health care services, and mortality. Assessments, among others Short Physical Performance Battery, Functional Independence Measure, Mini Nutritional Assessment, and Mini-Mental State Examination will be performed at the participant's home at baseline, 3, 6, and 12 months. Register data on the use and costs of social and health care services, and mortality will be monitored for 24 months.
Our trial will provide new knowledge on the potential of intensive, long-term home-based physiotherapy among older persons at risk for disabilities, to enhance functional capacity and thereby to postpone the need for institutional care, and diminish the use of social and health care services.

To evaluate the effect of cognitive training on cognition and health-related quality of life (HRQoL) in community-dwelling persons with dementia.
Single-blind randomized controlled trial with 3- and 9-month follow-up.
Adult day care centers in Helsinki, Finland.
Older individuals with mild to moderate dementia living at home and attending adult day care twice a week (N = 147; mean age 83, 72% female, 63% at mild stage of dementia).
A systematic 12-week training program focused on subskills of executive function: attention, working memory, cognitive flexibility, and planning. The intervention group (n = 76) underwent cognitive training twice a week for 45 minutes, and the control group (n = 71) attended day care as usual.
Primary outcomes were the Alzheimer's Disease Assessment Scale-Cognitive subscale (ADAS-Cog) for global cognition and the 15-dimensional instrument (15D) for HRQoL. The outcomes were measured at baseline and 3 and 9 months.
Both groups deteriorated in global cognition and HRQoL during follow-up, and there were no differences between the two groups in change on the ADAS-Cog (P = .43) or 15D (P = .61) over time (adjusted for age and sex). At 3 months, changes were 0.8 (95% confidence interval (CI) = -0.2-1.8) for the intervention group and 1.7 (95% CI = 0.6-2.7) for the control group on the ADAS-Cog and -0.040 (95% CI = -0.058 to -0.021) for the intervention group and -0.037 (95% CI = -0.056 to -0.018) for the control group on the 15D.
Systematic cognitive training had no effect on global cognition or HRQoL in community-living persons with mild to moderate dementia.

Few rigorous clinical trials have investigated the effectiveness of exercise on the physical functioning of patients with Alzheimer disease (AD).
To investigate the effects of intense and long-term exercise on the physical functioning and mobility of home-dwelling patients with AD and to explore its effects on the use and costs of health and social services.
A randomized controlled trial.
A total of 210 home-dwelling patients with AD living with their spousal caregiver.
The 3 trial arms included (1) group-based exercise (GE; 4-hour sessions with approximately 1-hour training) and (2) tailored home-based exercise (HE; 1-hour training), both twice a week for 1 year, and (3) a control group (CG) receiving the usual community care.
The Functional Independence Measure (FIM), the Short Physical Performance Battery, and information on the use and costs of social and health care services.
All groups deteriorated in functioning during the year after randomization, but deterioration was significantly faster in the CG than in the HE or GE group at 6 (P = .003) and 12 (P = .015) months. The FIM changes at 12 months were -7.1 (95% CI, -3.7 to -10.5), -10.3 (95% CI, -6.7 to -13.9), and -14.4 (95% CI, -10.9 to -18.0) in the HE group, GE group, and CG, respectively. The HE and GE groups had significantly fewer falls than the CG during the follow-up year. The total costs of health and social services for the HE patient-caregiver dyads (in US dollars per dyad per year) were $25,112 (95% CI, $17,642 to $32,581) (P = .13 for comparison with the CG), $22,066 in the GE group ($15,931 to $28,199; P = .03 vs CG), and $34,121 ($24,559 to $43,681) in the CG.
An intensive and long-term exercise program had beneficial effects on the physical functioning of patients with AD without increasing the total costs of health and social services or causing any significant adverse effects.

Besides cognitive decline, Alzheimer's disease (AD) leads to physical disability, need for help and permanent institutional care. The trials investigating effects of exercise rehabilitation on physical functioning of home-dwelling older dementia patients are still scarce. The aim of this study is to investigate the effectiveness of intensive exercise rehabilitation lasting for one year on mobility and physical functioning of home-dwelling patients with AD.
During years 2008-2010, patients with AD (n = 210) living with their spousal caregiver in community are recruited using central AD registers in Finland, and they are offered exercise rehabilitation lasting for one year. The patients are randomized into three arms: 1) tailored home-based exercise twice weekly 2) group-based exercise twice weekly in rehabilitation center 3) control group with usual care and information of exercise and nutrition. Main outcome measures will be Guralnik's mobility and balance tests and FIM-test to assess physical functioning. Secondary measures will be cognition, neuropsychiatric symptoms according to the Neuropsychiatric Inventory, caregivers' burden, depression and health-related quality of life (RAND-36). Data concerning admissions to institutional care and the use and costs of health and social services will be collected during a two year follow-up.
To our knowledge this is the first large scale trial exploring whether home-dwelling patients with AD will benefit from intense and long-lasting exercise rehabilitation in respect to their mobility and physical functioning. It will also provide data on cost-effectiveness of the intervention.

To evaluate the health-related quality of life (HRQoL) and functional capacity in relation to glycemic control among older home-dwelling primary care patients.
Electronic patient records were used to identify 527 people over 65 years with diabetes. Of these, 259 randomly selected subjects were invited to a health examination and 172 of them attended and provided complete data. The participants were divided into three groups based on the HbA1c: good (HbA1c57mmol/mol (N=29)) glycemic control. HRQoL was measured with the EuroQol EQ-5D questionnaire. Functional and cognitive capacity and mental well-being were assessed with the Lawton Instrumental Activities of Daily Living (IADL) scale, Mini-Mental State Examination (MMSE) and Geriatric Depression Scale (GDS-15).
EQ-5D scores for good, intermediate and poor glycemic control were 0.78; 0.74 and 0.70, p=0.037. Sub-items of mobility (p=0.002) and self-care were the most affected (p=0.031). Corresponding trend was found for IADL, p=0.008. A significant correlation was found between MMSE scores and HbA1c.
Older primary care home-dwelling patients with diabetes and poorer glycemic control have lower functional capacity and HRQoL, especially in regard to mobility and self-care.
objectively measured population physical activity (PA) data from older persons is lacking. The aim of this study was to describe free-living PA patterns and sedentary behaviours in Icelandic older men and women using accelerometer.
from April 2009 to June 2010, 579 AGESII-study participants aged 73-98 years wore an accelerometer (Actigraph GT3X) at the right hip for one complete week in the free-living settings.
in all subjects, sedentary time was the largest component of the total wear time, 75%, followed by low-light PA, 21%. Moderate-vigorous PA (MVPA) was
