RESUMO
Objectives: This study examined the social factors affecting the frequency of going out, and social isolation related to the frequency of daily conversation, stratified by gender. Method: The participants comprised 1,016 community-dwelling older Japanese adults, who were categorized into four groups: those who are (1) not isolated socially and go out every day, (2) not isolated socially and do not go out every day, (3) socially isolated and go out every day, and (4) socially isolated and do not go out every day. We performed a logistic regression analysis to assess the relationship between the frequency of daily conversation and the four groups. Results: Our multivariable logistic regression analysis (reference, group 1) showed that the coexistence of poor social factors significantly affected men (group 2: odds ratio [OR] 2.13 [1.10 to 4.12]; group 3: OR 2.92 [1.70 to 5.00]; and group 4: OR 4.28 [2.43 to 7.54]). For women, the frequency of going out was related to daily conversation only with social isolation group (group 2: OR 1.51 [0.77 to 2.98]; group 3: OR 2.42 [1.25 to 4.68]; and group 4: OR 3.81 [2.08 to 7.00]). Conclusion: Our findings suggest that promoting daily conversations of community-dwelling older adults can help prevent related health adversities.
RESUMO
INTRODUCTION: The regional cerebral blood flow (rCBF) distribution can affect brain functioning, leading to amnestic mild cognitive impairment (aMCI) and mild Alzheimer disease (AD). This study aimed to clarify the detailed characteristics of rCBF distribution in patients with mild AD and aMCI. METHODS: This cross-sectional study from April 2015 to March 2018 included 103 older adults (mean age 78.9 years; 60% females), out of a total of 302 adults, and categorized them into 3 groups according to cognitive symptoms. The normal control (NC), aMCI, and mild AD groups included 20, 50, and 33 participants, respectively. The primary outcome was rCBF, which was compared among the 3 groups using a 2-sample t test without correction for multiple comparisons. RESULTS: In the aMCI group, the rCBF decreased in the bilateral parietal and left frontal association cortex and the bilateral premotor cortex (p < 0.01) but increased in the bilateral cerebellum (p < 0.01). In the mild AD group, the rCBF decreased in the bilateral parietal and occipital association cortex, the bilateral premotor cortex, the left temporal and frontal association cortex, and the left limbic lobe (p < 0.01). Conversely, the rCBF increased in some parts of the cerebellum, the bilateral frontal and temporal association cortex, the left occipital association cortex, and the right premotor cortex (p < 0.01). CONCLUSION: Based on the analysis of the values obtained, it was inferred that the rCBF undergoes reduction and elevation in aMCI and AD patients.
RESUMO
PURPOSE: Physical and cognitive/psychological functions are risk factors for incident homebound status. However, there are only a few studies exploring the factors related to homebound status in hospitalized older patients. The aim of this study was to determine the relationship between physical, and cognitive/psychological function at discharge among hospitalized older patients and the risk of undergoing homebound status after discharge. METHODS: We analyzed the cohort data of hospitalized older patients (age ≥65 years) with internal medical problems. The main outcome was the incidence of homebound status a month after discharge. Physical functions were measured by handgrip strength (HG), knee extension strength (KES), one-leg stance (OLS), and walking speed (WS). Cognitive and psychological functions were assessed using the Mini-Mental State Examination (MMSE) and Geriatric Depression Scale-5 (GDS-5), respectively. Poisson regression models were used to estimate the risk ratios (RR) and 95 % confidence intervals (CIs) of the relationships between physical, cognitive, and psychological functions as well as the homebound status. RESULTS: A total of 178 participants who completed the follow-up were analyzed mean age (standard deviation) 76.2 (6.9) years. A month after discharge, 23 participants were deemed homebound, for a cumulative incidence (95 %CI) of 12.9 % (8.0 %-17.8 %). The RR (95 %CI) estimated by Poisson regression were 3.51 (1.30-9.48), 0.15 (0.03-0.72) and 0.11 (0.01-0.92) for low KES, maximum WS and comfortable WS, respectively. However, HG, OLS, MMSE, and GDS-5 were not significantly associated with the incidence of homebound status. CONCLUSION: Physical functions can predict the incidence of homebound status after discharge among hospitalized older patients.

BACKGROUND: Swallowing disorders are a serious health concern among older adults. Previous studies reported that sarcopenia may affect swallowing disorders; however, whether sarcopenia is related to the capacity to swallow (measured according to swallowing speed) in community-dwelling older adults is unclear. OBJECTIVES: The aim of this study was to investigate the relationship between sarcopenia and swallowing capacity in community-dwelling older women. METHODS: This cross-sectional observational study was conducted among community-dwelling older women in Japan. The inclusion criteria were as follows: women aged ≥65 years, with the ability to walk independently, and without dysphagia. The exclusion criterion was a history of stroke or Parkinson's disease that directly caused dysphagia. The participants were divided into a sarcopenia and a healthy group based on the criteria of the Asian Working Group for Sarcopenia 2019. We measured swallowing speed (mL/s) as the swallowing capacity by conducting a 100-mL water-swallowing test. To assess the relationship between sarcopenia and swallowing capacity, we performed a multiple regression analysis. RESULTS: Two-hundred and sixty participants were enrolled in the study. Their mean age was 82.3 ± 6.9 years, and 61 (23.5%) of them displayed sarcopenia. The mean swallowing speed was 11.5 ± 4.9 mL/s, and 17 women (6.5%) exhibited choking or a wet-hoarse voice. Multiple regression analysis revealed that sarcopenia was related to the swallowing capacity after adjusting for age, the Mini-Mental State Examination, and the number of comorbidities (ß = -0.20, 95% CI -3.78 to -0.86, p = 0.002). CONCLUSIONS: We found that sarcopenia was related to the swallowing capacity in older women in this study. Future research should clarify whether a similar relationship exists in older men as well as the effect of sarcopenia on the swallowing capacity in older adults over a period of time.

Factors associated with functional recovery after stroke may differ by age demographics because the aging process leads to various regressive changes. The aim of this study was to identify factors related to functional recovery in Japanese patients with convalescent stroke stratified by age. A multicenter retrospective observational study was conducted in 243 patients from six convalescent inpatient rehabilitation wards. Participants were categorized into three groups: 40-64, 65-74, and ≥75 years. Demographic data, laboratory data, physical function, and cognitive function were collected upon admission, and outcome measures were represented using the relative gain of the Functional Independence Measure (FIM effectiveness) during hospitalization. Stepwise multivariate logistic analysis was performed to identify the significant factors for functional recovery in each group. In the 40-64 years group, stroke type [odds ratio (OR), 10.38; 95% confidence interval (CI), 2.22-48.59], spatial neglect (OR, 7.61; 95% CI, 2.07-28.00), and memory disorder (OR, 4.68; 95% CI, 1.08-20.30) were shown to be significant factors. In the 65-74 years group, only memory disorder (OR, 3.42; 95% CI, 1.19-9.81) was significant. In the ≥75 years group, low albumin level (OR, 3.35; 95% CI, 1.05-10.67), severe motor impairment (OR, 5.11; 95% CI, 1.14-22.97), and memory disorder (OR, 4.34; 95% CI, 1.43-13.23) were significantly related to poor functional recovery. In conclusions, the findings showed that there were different trends among the factors related to poststroke functional recovery among the three age groups.
