Associations Between Environmental Characteristics and Life-Space Mobility in Community-Dwelling Older People
2015
Objective: To examine the association between perceived environmental barriers to and facilitators for outdoor mobility with life-space among older people. Methods: Community-dwelling, 75- to 90-year-old people ( n = 848) were interviewed face-to-face using standard questionnaires. The Life-Space Assessment (LSA), indicating distance and frequency of moving and assistance needed in moving (range 0-120), was used. Environmental barriers and facilitators outdoors were self-reported. Results: Altogether, 41% ( n = 348) of the participants had restricted life-space (LSA score < 60). Those reporting one or more environmental barriers had more than double the odds for restricted life-space co…
Validation of a pre-coded food diary Used among 60–80 year old men: Comparison of self-reported energy intake with objectively recorded energy expend…
2014
Published version of an article from the journal Plos One. Also available from the publisher: dx.doi.org/10.1371/journal.pone.0102029 Open Access Objective: To validate energy intake (EI) estimated from a pre-coded food diary (PFD) against energy expenditure (EE) measured with a valid physical activity monitor (SenseWear Pro3 Armband) and to evaluate whether misreporting was associated with overweight/obesity in a group of elderly men. Methods: Forty-seven healthy Norwegian men, 60–80 years old, completed the study. As this study was part of a larger intervention study, cross-sectional data were collected at both baseline and post-test. Participants recorded their food intake for four conse…
Patient-centred access to health care: a framework analysis of the care interface for frail older adults
2018
Abstract Background The objective of this study was to explore the issues surrounding access to health and social care services for frail older adults with Polish stakeholders, including healthy and frail/pre-frail older adults, health care providers, social care providers, and caregivers, in order to determine their views and perspectives on the current system and to present suggestions for the future development of a more accessible and person-centred health and social care system. Methods Focus groups were used to gather qualitative data from stakeholders. Data were analysed using framework analysis according to five dimensions of accessibility to care: approachability, acceptability, av…
Activity as a predictor of mental well-being among older adults
2006
This eight-year follow-up study examines the roles of physical and leisure activity as predictors of mental well-being among older adults born in 1904-1923. As part of the Evergreen project, 1224 (80%) persons aged 65-84 years were interviewed at baseline (1988), and 663 (90%) persons in the follow-up (1996). Mental well-being factors including depressive symptoms, anxiety, loneliness, self-rated mental vigour and meaning in life were constructed using factor analysis. The predictors of mental well-being included physical and leisure activity, mobility status and number of chronic illnesses. We used a path analysis model to examine the predictors of mental well-being. At baseline, low numbe…
Designing ICTs for Users with Mild Cognitive Impairment: A Usability Study
2020
Background: Research has supported the cost-effectiveness of cognitive training tools enhanced by information and communication technologies (ICT) in several populations, including individuals with mild cognitive impairment (MCI) and age-related cognitive decline. The implementation of ICTs in this population, however, is sometimes challenging to their cognitive and age characteristics. Ultimately, this might compromise the effectiveness of ICT-enhanced therapies in this population. The aim of this study is to test the usability and acceptability of a European project prototype for elderly care, in an attempt to explore the ICT design needs of users with MCI. Methods: Participants were 28 i…
Study of the Association with -330T/G IL-2 in a Population of Centenarians from Centre and South Italy.
2005
Immune response in elderly is characterised by a progressive loss of the ability to cope environmental stressors with a characteristic remodelling of cytokine network. One of the data constantly reported in literature is the decrease of IL-2 production. An IL-2 central role in the reconstitution of T cell function in vitro is largely documented. Studies on a T → G polymorphism at - 330 nt of IL-2 gene promoter region have demonstrated that T lymphocytes from 330GG homozygous subjects are able to produce in vitro higher amount of IL-2, than -330TG heterozygous or -330TT homozygous subjects. As a genetic background conditioning the maintaining of an efficient immune response would exert posit…
Diffusion Tensor Imaging of the Hippocampus in MCI and Early Alzheimer's Disease
2011
The hippocampus is among the first brain structures to be affected by Alzheimer's disease (AD) pathology. Microstructural alterations within this region have been quantified in vivo using diffusion tensor imaging (DTI), a relatively novel MRI-based technique for mapping diffusion properties of water. Existing evidence indicates that DTI-derived mean diffusivity (MD) of the anterior hippocampus is more predictive than ordinary volumetric indices of the degree of episodic memory impairment in patients with early AD. Thus, altered MD of the (anterior) hippocampus might be highly indicative of hippocampal dysfunction, thereby potentially qualifying this measure as a candidate marker for monitor…
Retirement age and type as predictors of frailty : a retrospective cohort study of older businessmen
2020
ObjectivesTo study the association between retirement characteristics and frailty in a homogenous population of former business executives.DesignCross-sectional cohort study using data from the Helsinki Businessmen Study.SettingHelsinki, Finland.Participants1324 Caucasian men, born in 1919–1934, who had worked as business executives and managers and of whom 95.9% had retired by the year 2000. Questions on age at and type of retirement, lifestyle and chronic conditions were embedded in questionnaires.Primary and secondary outcome measuresFrailty assessed according to a modified phenotype definition at mean age 73.3 years.ResultsMean age at retirement was 61.3 years (SD 4.3) and 37.1% had ret…
Cumulative Prognostic Score Predicting Mortality in Patients Older Than 80 Years Admitted to the ICU
2019
OBJECTIVES To develop a scoring system model that predicts mortality within 30 days of admission of patients older than 80 years admitted to intensive care units (ICUs). DESIGN Prospective cohort study. SETTING A total of 306 ICUs from 24 European countries. PARTICIPANTS Older adults admitted to European ICUs (N = 3730; median age = 84 years [interquartile range = 81‐87 y]; 51.8% male). MEASUREMENTS Overall, 24 variables available during ICU admission were included as potential predictive variables. Multivariable logistic regression was used to identify independent predictors of 30‐day mortality. Model sensitivity, specificity, and accuracy were evaluated with receiver operating characteris…
Harmonized benchmark labels of the hippocampus on magnetic resonance: The EADC-ADNI project
2015
Abstract Background A globally harmonized protocol (HarP) for manual hippocampal segmentation based on magnetic resonance has been recently developed by a task force from European Alzheimer's Disease Consortium (EADC) and Alzheimer's Disease Neuroimaging Initiative (ADNI). Our aim was to produce benchmark labels based on the HarP for manual segmentation. Methods Five experts of manual hippocampal segmentation underwent specific training on the HarP and segmented 40 right and left hippocampi from 10 ADNI subjects on both 1.5 T and 3 T scans. An independent expert visually checked segmentations for compliance with the HarP. Descriptive measures of agreement between tracers were intraclass cor…
