The effect of a multimodal intervention program on cognitive and daily function of older persons residing in rural communities: A pilot study.

This pilot study aimed to explore the effects of a 12-week multimodal intervention program, comprising cognitive training and cognitive-stimulation, on cognitive performance and daily function of older adults in rural communities. Fifty-one participants were equally assigned to the multimodal intervention, cognitive-stimulation, and no-intervention control groups. Cognition and daily function were assessed using the Korean version of neuropsychological test battery and instrumental activities of daily living at baseline and at the 12-week follow-up assessment, respectively.

Television Viewing and Cognitive Dysfunction of Korean Older Adults.

This study examined the association between television (TV) viewing and cognitive dysfunction in elderly Koreans. Among participants of the 2014 National Survey of Older Koreans, 9644 were considered in this study. To better identify the association between two factors, propensity score (PS) matching with exact method was used.

Impact of Cognitive Aging on Health-Related Quality of Life in Menopausal Women.

Objectives: Menopause is a well-known risk factor for accelerating cognitive aging in women. This study aimed to assess differences in cognitive function and health-related quality of life (HRQOL) according to menopausal status to determine whether the menopause significantly affects the relationship between cognitive function and HRQOL.

Methods: This was a cross-sectional comparative study with a convenience sample of 178 Korean women including 89 naturally menopausal women (65 ± 10 years) and 89 non-menopausal women (45 ± 8 years) who met the eligibility criteria and completed neuropsychological tests and self-report questionnaires about their HRQOL, cognitive function, depression, and sleep quality.

Different Effects of Cognitive and Non-exercise Physical Leisure Activities on Cognitive Function by Age in Elderly Korean Individuals.

Objectives: We aimed to examine the effects of various leisure activities on cognitive impairment in young-old (aged 65-74 years) and old-old (aged ≥ 75 years) adults.

Methods: In total, 10,279 elderly Korean individuals from the 2014 Korean National Survey on Older Adults' cohort were enrolled in our study. Cognitive impairment was assessed using the standardized score of the Mini-Mental State Examination for Dementia Screening, whereas leisure activities were recorded via self-reporting of the extent and type of leisure activity the subjects involved in over the past year.

Design of deformable chitosan microspheres loaded with superparamagnetic iron oxide nanoparticles for embolotherapy detectable by magnetic resonance imaging.

The purpose of this study was to design chitosan microspheres (MS) loaded with superparamagnetic iron oxide nanoparticles (SPIO) suitable for anti-cancer embolotherapy detectable by MRI. Deformable chitosan MS loaded with varying SPIO concentrations (SPIO-chitosan MS) were prepared by ionotropic gelation and a porogenic technique using polyethylene glycol, followed by genipin crosslinking. Adding SPIO nanoparticles to chitosan MS did not significantly affect the chitosan MS morphology.
