[Purpose] To evaluate the effect of a home exercise program on physical function in community dwelling elderly with pre-sarcopenia or sarcopenia. [Subjects and Methods] Fifty-two community-dwelling individuals, over 60 years and meeting the diagnostic criteria for pre-sarcopenia or sarcopenia, were randomly assigned to intervention group (n=34) and control group (n=18). The intervention group completed 6-months home exercise programs, combining walking with lower limb resistance exercises. Body mass index, skeletal mass index, body fat percentage, handgrip strength, single-leg standing, walking speed (comfortable and maximal), and knee extension strength were evaluated at baseline and post-intervention. Activity was assessed using the 25-question Geriatric Locomotive Functional Scale (GLFS-25) and quality of life using the Euro QOL questionnaire. [Results] Pre- and post-training assessments were completed by 76.5% and 77.8% of participants in the intervention and control groups, respectively. The intervention improved single-leg standing (60.5 s to 77.2 s) and knee extension strength (1.38 Nm/kg to 1.69 Nm/kg). In the control group, maximum walking speed (2.02 m/s to 1.86 m/s) and GLFS-25 score (2.9 to 5.1) worsened. Change of pre-sarcopenia/sarcopenia status was comparable for the intervention (15.4%) and control (14.3%) groups. [Conclusion] A 6-month home exercise program improved physical function in community-dwelling individuals with pre-sarcopenia or sarcopenia.

We aimed to detect brain abnormalities during cognitive and motor tasks in older individuals with pre-frailty, as this could prevent dementia. Sixty elderly participants (mean age: 76.3 years; 27 healthy and 33 with pre-frailty) were included, and their motor function, cognitive function, and dual-task abilities (gait with calculation and while carrying a ball) were evaluated. Total hemoglobin (t-Hb) was measured using functional near-infrared spectroscopy (fNIRS) during tasks and resting periods. The pre-frailty group had a slightly lower gait speed than the healthy group, but there was no significant difference in cognitive function. In the pre-frailty group, the t-Hb values during the normal gait and cognitive tasks were higher than the resting value in the right prefrontal cortex, while in the healthy group, only the word frequency task (WFT) was higher. Furthermore, in the WFT, the t-Hb values were significantly lower in the pre-frailty group than in the healthy group. The results showed that pre-frail subjects had lower brain activation during the WFT in the right prefrontal cortex and excessive activity during walking, even without a noticeable cognitive decline. The differences in cerebral blood flow under the pre-frailty conditions may be a clue to detecting cognitive decline earlier.

Objectives To clarify the prevalence and characteristics of pain associated with sarcopenia and to verify the usefulness of evaluation of pain for sarcopenia. Methods In total, 759 community-dwelling people (aged 65–79 years) with or without sarcopenia and lower limb pain were classified into 4 groups (NSp, nonsarcopenia; NSpP, nonsarcopenia with pain; Sp, sarcopenia; and SpP, sarcopenia with pain). Body composition, motor function, history of fractures since age 50 years, and number of falls in the past 1 year were compared between the groups. Results Participant proportions by group were: NSp, 53.9%; NSpP, 42.8%; Sp, 1.3%; and SpP, 2.0%. Participants with lower limb pain showed low single leg standing, walking speed, and 2-step value scores and high 25-question Geriatric Locomotive Functional Scale (GLFS-25) score after adjusting for age, sex, body mass index, and presence of sarcopenia. The SpP group showed lower functional reach test and higher GLFS-25 scores than the Sp group. Regarding the history of fractures since 50 years of age and falls in past 1 year, a high retention rate of fracture was noted in the NSpP group. They also experienced significantly more falls in the past 1 year than those in the NSp group. The SpP group noted more falls and fractures although it was insignificant. Conclusions The results indicate that participants with lower limb pain showed declining motor function and a high risk for falls and fractures. Sarcopenia could escalate this risk. Therefore, evaluating patients for both pain and sarcopenia may be useful for risk assessment and treatment.

Using specific CT findings from patients with ovarian cancer, we have devised two predictive models that have an accuracy of greater than 90% for predicting whether cytoreductive surgery will completely remove all tumor tissue, which should greatly aid in the differential decision-making as to whether to attempt cytoreductive surgery first, or to advance directly to neoadjuvant chemotherapy.
