“…Covid-19 pandemic and associated measures such as social distancing and lockdown has resulted in reduction of physical activity and alteration in dietary habit increasing sarcopenia prevalence (51). While previous studies have emphasized on the need of resistance exercise and protein supplement, our study is the first to document improvement in gait speed, with reduction in the prevalence of SG and poor HGS after 3 months of dualtask exercise.…”

Background: Sarcopenia is defined as a progressive age-related loss in muscle mass and strength affecting physical performance. It is associated with many negative outcomes including falls, disability, cognitive decline, and mortality. Protein enriched diet and resistance training have shown to improve muscle strength and function but there is limited evidence on impact of dual-task exercise in possible sarcopenia.Objective: To evaluate impact of community-based dual-task exercise on muscle strength and physical function in possible sarcopenia defined by either slow gait (SG) or poor handgrip strength (HGS). The secondary aims include effect on cognition, frailty, falls, social isolation, and perceived health.Methods: Community-dwelling older adults ≥60 years old were recruited from screening program intended to identify seniors at risk, and invited to participate in dual-task exercise program called HAPPY (Healthy Aging Promotion Program for You). One hundred and eleven participants with possible sarcopenia completed 3 months follow-up. Questionnaire was administered on demographics, frailty, sarcopenia, falls, perceived health, social network, functional, and cognitive status. Physical performance included assessment of HGS, gait speed, and Short Physical Performance Battery test (SPPB).Results: The mean age of the Exercise group was 75.9 years old and 73.0% were women. The Exercise group had more female (73.0 vs. 47.5%), were older (75.9 vs. 72.5 years old), had higher prevalence of falls (32.4 vs. 15.0%), lower BMI (23.7 vs. 25.8), and education (4.0 vs. 7.2 years). The gait speed of the Exercise group increased significantly with significant reduction in the prevalence of SG and poor HGS. All components of SPPB as well as the total score increased significantly while the prevalence of pre-frailty and falls dropped by half. The risk of social isolation reduced by 25% with significant improvement in perceived health and cognition in the Exercise group. Significant impact on improvement gait speed and SPPB persisted after adjustment for baseline factors.Conclusion: Dual-task exercise program is effective in improving gait speed, SPPB score, and reducing the prevalence of poor HGS with significant improvement in perceived health, cognition, and reduction in falls and frailty. Future prospective randomized control trials are needed to evaluate the effectiveness of dual-task interventions in reversing sarcopenia.

“…While older people are recognized as the most vulnerable group in terms of hospitalization and death, such that pandemic policies place vaccinations of older adults of the highest importance, the adverse health and social consequences of pandemic policies have received little attention. Among Western societies it has been pointed out that COVID-19 has given rise to some of the worst examples of ageism, where the pandemic has been characterized as 'the boomer remover', where age becomes a rationing criteria for use of ventilators in Italy, and unwillingness to adopt social distancing measures by younger people to protect their older relatives [6]. Hong Kong cannot be said to be deficient in its intensive care provisions in normal circumstances, such that age alone will not be used as a criteria for rationing.…”

“…Taking recent years as an example, the number of Atlantic hurricanes reached a new high in 2020, with Central America experiencing unprecedented Category 4 hurricanes in November [4]. In the same year, the world faced large impacts from the COVID-19 pandemic [5,6]. In 2021, North America experienced unusual high temperatures, with July becoming the hottest month on record globally, while Europe faced record-breaking rainfall and flooding [7,8].…”

Global energy consumption is growing rapidly, with the frequency and intensity of extreme events constantly increasing, posing a long-term threat to power supply and consumption. Therefore, analyzing the spatiotemporal characteristics of electricity consumption and quantitatively assessing the impact of extreme events on electricity consumption are of great significance. Based on fine-grained electricity consumption data from Europe for the years 2019–2022, this paper employs a data mining perspective and four methods including Z-score, Isolation Forest, Local Outlier Factor, and Autoencoder to detect abnormal electricity consumption during extreme events. Additionally, it combines indicators such as elastic loss, vulnerability, and duration to measure the impact of extreme events on electricity consumption. It is found that low temperatures could lead to abrupt changes in electricity consumption, with Northern Europe being more significantly affected by low temperatures. The COVID-19 pandemic had the most significant impact on electricity consumption in Europe, with the middle part of Europe being the hardest hit during the first wave of the pandemic. Electricity anomalies during the pandemic period were related to national pandemic control policies and exhibited some lag. High temperatures persisted for a longer duration in the middle part of Europe.
