Background: As the community-dwelling population ages in Taiwan, concerns regarding long-term care have grown more urgent. Physical fitness plays a key role in enabling community-dwelling older adults to independently complete daily tasks and avoid falling accidents. However, the effect of physical fitness on falls and other fitness-related factors remains poorly understood.Methods: In this retrospective cross-sectional study, 2130 community-dwelling older adults were recruited from a rural region of Taiwan. Each of these participants completed a demographics interview and frailty questionnaire and reported their history of falls. We evaluated each participant’s height and body weight measurements, calf circumference, bone mass density, and results on the grip strength, single-leg standing, chair sit-and-reach, 8-ft up-and-go, 30-second chair stand, 2-minute step, 30-second arm curl, 6-m walk, and back scratch tests to determine their overall physical fitness, which consisted of their body composition, muscular strength and endurance, flexibility, and cardiopulmonary fitness.Results: The prevalence of falls in the preceding year among the older adults surveyed was 20.8%, and the resultant hospitalization rate was 10.9%. The older adults who were more physically active in the past week, had regular exercise habits, lived with family, and had no history of hospitalization due to falls, exhibited greater performance on the physical fitness tests. Three time fallers exhibited lower levels of overall physical fitness than did those who had not fallen. The nonfallers outperformed the fallers in grip strength (participants who had not fallen and those who had fallen once, twice, or three times in the preceding year: 24.66 ± 0.19 vs. 23.66 ± 0.35 vs. 20.62 ± 0.71 vs. 22.20 ± 0.90 kg) and single-leg standing duration (19.38 ± 0.39 vs. 16.33 ± 0.78 vs. 13.95 ± 1.67 vs. 12.34 ± 1.82 seconds).Conclusions: Exercise habits, living status, hospitalization due to falls, and amount of exercise were all associated with physical fitness in community-dwelling older adults. The results of all of the assessments indicated that the participants who had fallen three times exhibited lower levels of physical fitness than did those who had not fallen in the previous year. Physical measurements, including grip strength and single-leg standing duration, are associated with an individual’s risk of falling, which indicates that they should be considered in the development of geriatric physical fitness and fall-prevention programs.

Background/Aim: Sorafenib, an oral multi-kinase inhibitor, has been shown to improve the outcome of patients with osteosarcoma (OS). However, the anti-OS effect and mechanism of sorafenib has not yet been fully understood. The main purpose of this study was to investigate the effect of sorafenib on apoptotic signaling and Nuclear Factor-κB (NF-κB)-mediated anti-apoptotic and metastatic potential in OS in vitro. Materials and Methods: The effect of sorafenib on apoptotic signaling transduction, anti-apoptotic, and metastatic potential of OS U-2 cells was verified with flow cytometry, trans-well invasion/migration, and western blotting assay. Results: Sorafenib induced the extrinsic and intrinsic apoptotic pathways. In addition, sorafenib reduced the invasion and migration ability of OS cells, induced NF-κB activation, and the expression of anti-apoptotic proteins and metastasis-associated proteins encoded by NF-κB target genes. Conclusion: Sorafenib led to stimulation of extrinsic/intrinsic apoptotic pathways and NF-κB inactivation in U-2 OS cells.

Sarcopenia is typically assessed through hand grip strength, walking speed, and chair stand tests. However, it has been inadequately examined in terms of other physical fitness (PF) components in community-dwelling older adults. Thus, in this study, we explored factors influencing the risk of sarcopenia in community-dwelling older adults. In addition, we analyzed the clinicodemographic characteristics of older adults with or without sarcopenia and investigated the effect of sex on their PF. This cross-sectional study included 745 older adults from a community health promotion program in Taiwan. Their clinicodemographic characteristics were recorded. PF was assessed through various tests, such as hand grip strength evaluation, 8-foot up-and-go test (8-UGT), 2-min step test, and 6-m walk test. PF and factors influencing sarcopenia risk were compared between older adults with sarcopenia (sarcopenia group) and those without it (nonsarcopenia group). A logistic regression model was performed to identify key factors associated with sarcopenia. Its predictive performance was evaluated by calculating the area under the receiver operating characteristic curve (ROC) curve. Regardless of sex, the sarcopenia group performed worse in almost all components of PF—for example, upper and lower limb muscular strength and endurance, cardiopulmonary fitness, and balance—than did the nonsarcopenia group. However, for men, no significant between-group difference was observed in flexibility. The logistic regression model indicated age (odds ratio [OR]: 1.107), sex (OR: 2.881), Mini Nutritional Assessment—Short Form scores (OR: 0.690), and performance in 8-UGT (OR: 1.346) as factors influencing the risk of sarcopenia. The model exhibited excellent discriminative ability in predicting sarcopenia, as indicated by an area under the curve value of 0.867 (95% confidence interval: 0.827–0.906; p < 0.05). Older adults without sarcopenia tend to outperform those with sarcopenia in almost all PF measures, regardless of sex. Older age, male sex, low Mini Nutritional Assessment—Short Form scores, and poor performance in 8-UGT are associated with a high risk of sarcopenia.

Background: The Taiwanese government implemented stringent preventative health measures to curb the spread of COVID-19. However, these measures negatively affected the physical activity behaviors and psychological distress of individuals. In this study, we investigated the effects of Taiwan’s COVID-19 alert–based restrictions on the physical activity behaviors and psychological distress of community-dwelling older adults. Methods: In this longitudinal study, 500 community-dwelling older adults were randomly sampled from a health promotion center in Taiwan. Telephone interviews were conducted between May 11, 2021, and August 17, 2021, which coincided with the Level 3 alert period when group physical activities were prohibited. Telephone interviews were again conducted between June 20, 2022, and July 4, 2022, after the alert level was reduced to Level 2 but group physical activities were prohibited period. Through the telephone interviews, data regarding the participants’ physical activity behaviors (type and amount) and 5-item Brief Symptom Rating Scale (BSRS-5) scores were collected. Moreover, data regarding physical activity behaviors were collected from the records of our previous health promotion programs, which were conducted before the national alert period. The obtained data were analyzed. Results: The alert levels influenced physical activity behaviors. Because of strict regulations, physical activity amount decreased during the Level 3 alert period and did not recover rapidly during the Level 2 alert period. Instead of engaging in group exercises (e.g., calisthenics and qigong), the older adults chose to exercise alone (e.g., strolling, brisk walking, and biking). Our findings indicate that the COVID-19 alert level has a significant influence on the amount of physical activity for participants (p < 0.05, partial η2 = 0.256), with pairwise comparisons showing that the physical activity amount decreased significantly across the three time periods (p < 0.05). The psychological distress of the participants did not appear to change during the regulation period. Although the participants' overall BSRS-5 score was slightly lower during the Level 2 alert period compared to the Level 3 alert period, the difference was not statistically significant (p = 0.264, Cohen's d = 0.08) based on a paired t-test. However, the levels of anxiety (p = 0.003, Cohen's d = 0.23) and inferiority (p = 0.034, Cohen's d = 0.159) were considerably higher during the Level 2 alert period than during the Level 3 alert period. Conclusions: Our findings indicate that Taiwan’s COVID-19 alert levels influenced the physical activity behaviors and psychological distress of community-dwelling older adults. Time is required for older adults to regain their prior status after their physical activity behaviors and psychological distress were affected by national regulations.
