“…Cognition was assessed using the Quick Mild Cognitive Impairment Screen (QMCI). The components of the QMCI include orientation (/10), word registration (/5), clock drawing (/15), delayed recall (/20), verbal fluency (/20) and logical memory (/30) [21]. These areas are scored differently, with a total QMCI score of 100, with < 62/100 being predictive of mild cognitive impairment (MCI) or dementia [21].…”

Prevalence of sarcopenia and associated factors in older adults attending a day hospital service in Ireland

The aim of this study was to describe the prevalence and associated factors of sarcopenia in community-dwelling older adults attending a day hospital service in Ireland, using the latest European Working Group of Sarcopenia in Older People (EWGSOP) guidelines. Findings The prevalence of sarcopenia in older adults attending a day hospital service in Ireland was 27-37% and varied depending on the strength test used. Sarcopenia was associated with older age, female gender, reduced BMI, reduced calf circumference, frailty, malnutrition, and reduced gait speed, irrespective of how muscle strength was assessed. Message Further consideration on the assessment of sarcopenia needs to be considered, regarding the use of muscle strength assessment, whether to assess upper limb, lower limb, or both.

Objectives: The aim of this study was to describe the associations between sarcopenia and variables derived from wrist accelerometry in community-dwelling older adults attending a day hospital service in Ireland. Methods: An observational cross-sectional study was carried out using a consecutive series of older adults attending a day hospital service. Sarcopenia was diagnosed using the latest European Working Group of Sarcopenia in Older People guidelines. Accelerometers were worn by each participant for a 7-day period on their non-dominant wrist. Results: Thirty-eight out of forty-one participants (93%) met the accelerometer wear time criterion and were included in statistical analyses. Included participants had a mean age of 81.1 years (standard deviation 6.2). Both sarcopenia (Grip) and sarcopenia (Lower limb) were associated with increased time spent in low physical activity and reduced average of Kcals per hour. Only sarcopenia (Lower limb) was associated with increased time in sedentary behaviour as well as reduced number of steps taken in a week. Conclusions: Accelerometer data can be used in an older day hospital population to track physical activity levels and sedentary behaviours. The assessment tool used to assess muscle strength and the cut-off criteria for physical activity behaviour influences the association with sarcopenia.

Patients with amnestic mild cognitive impairment (aMCI) are at high risk of developing dementia. This study used resting-state functional magnetic resonance imaging (rs-fMRI) and an independent component analysis (ICA) approach to explore changes in functional connectivity (FC) in the default mode network (DMN), executive control network (ECN), and salience network (SN). Thirty patients with aMCI and 30 healthy controls (HCs) were enrolled. All the participants underwent an rs-fMRI scan. The brain FC in DMN, ECN, and SN was calculated using the ICA approach. We found that the FC of brain regions in DMN decreased significantly and that of brain regions in ECN increased, which was in accordance with the findings of previous studies on Alzheimer's disease (AD) and aMCI. We also found that the FC of brain regions in SN increased, which was different from the findings of previous studies on AD. The increase in FC in brain regions in SN might result from different pathophysiological states in AD and aMCI, indicating that a decrease in FC in SN does not occur in a person with aMCI. These results are consistent with those of previous studies using the voxel-mirrored homotopic connectivity approach and seed-based correlation analysis. We therefore considered that the decrease in FC in DMN and the increase in FC in ECN and SN might be peculiar patterns observed on the rs-fMRI of a person with aMCI. These findings may contribute to the development of imaging biomarkers for the diagnosis of aMCI.
