Structural integrity of the corpus callosum predicts long-term transfer of fluid intelligence-related training gains in normal aging
2012
Although cognitive training usually improves cognitive test performance, the capability to transfer these training gains into respective or functionally related cognitive domains varies significantly. Since most studies demonstrate rather limited transfer effects in older adults, aging might be an important factor in transfer capability differences. This study investigated the transfer capability of logical reasoning training gains to a measure of Fluid Intelligence (Gf) in relation to age, general intelligence, and brain structural integrity as measured by diffusion tensor imaging. In a group of 41 highly educated healthy elderly, 71% demonstrated successful transfer immediately after a 4-…
Luminescence of GeO2 glass, rutile-like and α-quartz-like crystals
2006
Abstract The luminescence of GeO 2 rutile-like crystals was studied. Crystals were grown from a melt of germanium dioxide and sodium bicarbonate mixture. Luminescence of the crystal was compared with that of sodium germanate glasses produced in reduced and oxidized conditions. A luminescence band at 2.3 eV was observed under N 2 laser (337 nm). At higher excitation photon energies and X-ray excitation an additional band at 3 eV appears in luminescence. The band at 2.3 eV possesses intra-center decay time constant about 100 μs at 290 K and about 200 μs at low temperature. Analogous luminescence was obtained in reduced sodium germanate glasses. No luminescence was observed in oxidized glasses…
Modifiable Lifestyle Factors and Cognitive Function in Older People: A Cross-Sectional Observational Study
2019
Background: The development of evidence-based interventions for delaying or preventing cognitive impairment is an important challenge. Most previous studies using self-report questionnaires face problems with reliability and consistency due to recall bias or misclassification among older people. Therefore, objective measurement of lifestyle components is needed to confirm the relationships between lifestyle factors and cognitive function. Aims: The current study examined the relationship between lifestyle factors collected with wearable sensors and cognitive function among community-dwelling older people using machine learning. Methods: In total, 855 participants (mean age: 73.8 years) wore…
Dietary intake and food pattern among university students
2000
Dietary intake and food pattern were determined among university students. Nine hundred-eighteen students (384 males and 534 females) completed a 24 hour recall and a questionnaire. This study showed an average energy intake of 10.3 and 8.0 MJ among male and female university students. The mean intakes of energy and magnesium for males and energy, iron, magnesium and zinc for females were lower to the Spanish Recommended Intakes. For males, breakfast, lunch, dinner and snacks bring about 18, 33, 25 and 27% of total dairy energy, respectively, however, for females a 15, 34, 23 and 27% of total dairy energy were obtained for breakfast, lunch, dinner and snacks, respectively. The university po…
Assessing physical performance and physical activity in large population-based aging studies: home-based assessments or visits to the research center?
2019
Abstract Background The current study aims to compare correlations between a range of measures of physical performance and physical activity assessing the same underlying construct in different settings, that is, in a home versus a highly standardized setting of the research center or accelerometer recording. We also evaluated the selective attrition of participants related to these different settings and how selective attrition affects the associations between variables and indicators of health, functioning and overall activity. Methods Cross-sectional analyses comprising population-based samples of people aged 75, 80, and 85 years living independently in Jyväskylä, Finland. The AGNES stud…
Characterization of Metabolically Healthy Obese People and Metabolically Unhealthy Normal-Weight People in a General Population Cohort of the ABCD St…
2017
There is actually no consensus about the possibility that in some instances, obesity may be a benign metabolically healthy (MH) condition as opposed to a normal-weight but metabolically unhealthy (MUH) state. The aim of this study was to characterize MH condition and to investigate possible associations with metabolic and cardiovascular complications. One thousand nineteen people (range of age 18–90 years) of the cohort of the ABCD_2 study were investigated. Participants were classified as normal weight (BMI < 24.9 kg/m2) or overweight-obese (BMI ≥25 kg/m2); they were also classified as MH in the presence of 0-1 among the following conditions: (a) prediabetes/type 2 diabetes, (b) hyperte…
Recommendations for and warnings against physical activity given to older people by health care professionals.
2005
Abstract Background Little is known about how health care professionals advice older people with chronic conditions about physical exercise. This study investigated exercise counseling in the context of health care as perceived by older people, and factors associated with perceived advice. Design and methods Participants were 580 non-institutional 73- to 92-year-old people who reported at least one contact with health care during the previous 12 months. Results Of all the participants, 23% recalled solely recommendations to exercise, and 9% solely warnings against exercise. Additionally, 34% recalled receiving both recommendations for and warnings against physical activity, and 34% did not …
Visual memory in Alzheimer patients: effects of practice, retention interval and severity of cognitive decline.
1995
The study was aimed at estimating the effect size of practice, retention interval and dementia severity on free recall performance in Alzheimer patients. Patients met DSM-III-R criteria for dementia of Alzheimer type. Different picture sets were presented on 4 days. The forgetting curves on different days were compared using ANOVA for repeated measurements. Practice had a minor, but significant negative effect on recall performance explaining 1% of the variance in recall performance. The retention interval varied between zero and 24 h explaining 23% of the total variance. Dementia severity explained 52% of the variance. For the development of memory improvement strategies in Alzheimer patie…
Reminiscence and dementia: a therapeutic intervention.
2015
ABSTRACTBackground:Dementia is a significant public health problem. One non-pharmacological therapy that has shown its effectiveness is reminiscence, which is a psychological intervention designed to address issues of particular relevance to older adults. The aim of this study was to examine the benefits of an integrative reminiscence program in elderly people with dementia.Methods:A quasi-experimental design and purposeful sampling were conducted at two retirement homes. Forty-two elderly adults with dementia were studied to measure the effect of the therapy (23 in the experimental group and 19 in the control group). The treatment group activity was held in 10 sessions.Results:The treatmen…
Schlafenszeiten, Fernseh- und Computergewohnheiten von Grundschulkindern in Deutschland
2007
Background Pediatricians recommend daily sleep of at least ten hours for children aged 9 and 10 years. Sufficient sleep is necessary for maintaining the body's homeostasis, as well as for fixing memories and learning. Lack of sleep in children has been associated with a diminished school performance, reduced attention span, and obesity. Adulthood is influenced by childhood lifestyle habits. Data from 4th graders in 34 schools in Mainz and its surroundings were analysed in order to determine negative health lifestyle factors in German primary school children, such as lack of sleep and increased leisure time spent watching television and computer gaming. Methods Data from a cross-sectional st…
