“…Similarly, a meta-analysis that included 1300 incident cases of all-cause dementia occurring after 10 years from the start of follow-up also found a null association between leisure-time physical activity and dementia, and suggested a reverse causation bias. 15 In contrast, although daily total physical activity, including leisure-time physical activity and nonexercise physical activity, contributes to total daily energy expenditure and thereby also confers important health benefits, 16,17 only a few epidemiological studies 3,8,9 have focused on the association between daily total physical activity and risk of dementia. These studies reported an association between a high level of daily total physical activity and risk of dementia but did not consider the possibility of reverse causation bias because of their short follow-up.…”

Key Points Question What are the associations of daily total physical activity, total moderate-to-vigorous physical activity (MVPA), and leisure-time MVPA with risk of dementia in the general population in Japan? Findings This cohort study including 43 896 participants investigated associations of daily total physical activity and total MVPA with risk of disabling dementia. However, a higher level of leisure-time MVPA was statistically significantly associated with decreased risk of disabling dementia in men. Meaning These findings suggest that higher leisure-time MVPA may be associated with the prevention of disabling dementia in men.

The regularity in the distribution of young stellar groups along the spiral arms of galaxies, first discovered by Bruce and Debra Elmegreen in 1983, was considered a rather rare phenomenon. However, recent studies of the spatial regularities in the distribution of the young stellar populations along the arms of the spiral galaxies NGC 628, NGC 895, NGC 4321, NGC 5474, NGC 6946, as well as along the rings of the spiral galaxy NGC 6217 and the lenticular galaxy NGC 4324, have revealed that this spatial (quasi) regularity and/or the presence of regular chains of star-forming regions is a fairly common phenomenon. Across all galaxies, the characteristic regularity scale is 350-500 pc or a multiple thereof. It should be noted that theoretical models predict an instability scale of a stellar-gas disk on the order of a few kpc, which is several times larger than what has been observed. The paper is partly based on the report presented at the

“…In each model, we investigated the relationship between PhA and physical function (grip strength, walking speed, TUG), physical activity (LSA), and QOL (JOABPEQ sub-items, EQ-5D) using multiple regression analysis with PhA as the objective variable. Grip strength, TUG, and 10-meter walk tests are easy and practical tools to assess patients' physical abilities, and these physical assessments have been used in patients with LSS in clinical settings [15,25,26]. Thus, we applied these items in this study.…”

Purpose Lumbar spinal stenosis (LSS) causes various symptoms, which can interfere with daily life and Quality of Life (QOL). Evaluating both patients’ physical function and QOL and helping them to improve is the focus of rehabilitation. Phase angle (PhA) assessment has been widely used to measure body composition, and it has been reported to reflect physical function and QOL. The purpose of this study was to investigate the relationship between PhA and physical function, physical activity, and QOL in patients with LSS. Methods PhA, handgrip strength, walking speed, timed up and go test (TUG), Life Space Assessment (LSA), Prognostic Nutritional Index (PNI), Japanese Orthopaedic Association back pain evaluation questionnaire (JOABPEQ), and EQ-5D were assessed. Multiple regression analysis was conducted to investigate the relationship of PhA to physical function, physical activity, and QOL using. Results Statistical analysis was performed on 104 patients with LSS. The results of multiple regression analysis of PhA adjusted for age, gender, and BMI (Model 1) and PhA adjusted for age, gender, BMI, and PNI (Model 2) compared with physical function and physical activity showed significant correlations respectively (P<0.05) in handgrip strength, walking speed, TUG, and LSA. In QOL assessment, both models showed a significant correlation (P<0.05) with lumbar function in JOABPEQ and a significant trend (P<0.1) in EQ-5D. Conclusion PhA in LSS patients in this study was associated with physical function and QOL, and may be a useful new tool for clinical evaluation in preoperative LSS patients.
