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.
In Norway, there is a focus on home-dwelling people with dementia receiving the opportunity to participate in organized meaningful activities. The aim of this study was to elucidate the experiences of home-dwelling persons with early-stage dementia who attend an activity center and participate in adapted physical and social activities delivered by nurses and volunteers.
The study adopted a qualitative approach, with individual interviews conducted among eight people diagnosed with early-stage dementia. The interview texts were analyzed using manifest and latent content analysis.
Four categories, ie, "appreciated activities", "praised nurses and volunteers", "being more active", and "being included in a fellowship", as well as the overall theme "participation in appreciated activities and a sense of feeling included in a fellowship may have a positive influence on health and well-being" emerged in the analysis. The informants appreciated the adapted physical and social activities and expressed their enjoyment and gratitude. They found the physical activities useful, and they felt themselves to be included in a fellowship through cheerful nurses and volunteers. The nurses were able to create a good atmosphere and spread joy in the center together with the volunteers. The informants felt themselves valued as the persons they were. These findings indicated that such activities may have had a positive influence on the informants' health and well-being.
In order to succeed with this kind of activity center, it is decisive that the nurses are able to tailor meaningful activities and create an environment where the persons with dementia can feel that they are respected and valued. The municipality health care service should implement such activity centers with specialist nurses in dementia care together with volunteers.

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.

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

The aim of the study is to generate knowledge on the use of Global Positioning Systems (GPS) to support autonomy and independence for persons with dementia. By studying a larger cohort of persons with dementia (n=208) and their caregivers, this study provides essential knowledge for planning and implementing GPS technology as a part of public health care services. Commercially available GPS technology was provided to the cohort of 208 persons with dementia from nineteen different Norwegian municipalities. The participants used GPS when performing outdoor activities as part of their daily life during a period of time between 2012 and 2014. Their family caregivers were instructed on how to use the GPS technology for locating the participants. The study documents that using GPS for locating persons with dementia provide increased safety for the person with dementia, their family caregivers and their professional caregivers. Furthermore the results confirm that by using GPS, persons with dementia may maintain their autonomy, enjoy their freedom and continue their outdoor activities despite the progression of the disease. Preconditions for successful implementation are that health professionals are trained to assess the participant's needs, that ethical dilemmas are considered, that caregivers have adequate knowledge about using the technology and that procedures and routines for administrating the GPS and locating persons with dementia are established. Early intervention and close collaboration between persons with dementia, family caregivers and professional caregivers are important for successful implementation of GPS in public health care.
