The Association between Influenza Vaccination and the Risk of SARS-CoV-2 Infection, Severe Illness, and Death: A Systematic Review of the Literature.
We reviewed the association between seasonal influenza vaccination and the risk of SARS-CoV-2 infection or complicated illness or poor outcome (e.g., severe disease, need for hospitalization or ventilatory support, or death) among COVID-19 patients. None of the studies that were reviewed (n = 12) found a significant increase in the risk of infection or in the illness severity or lethality, and some reported significantly inverse associations. Our findings support measures aimed at raising influenza vaccination coverage in the coming months.

Meta AnalysisEffectiveness of Traditional Chinese Exercise for Symptoms of Knee Osteoarthritis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials.
Background: Growing evidences have advocated the potential benefits of traditional Chinese exercise (TCE) on symptomatic improvement of knee osteoarthritis (KOA). However, most of them have been derived from cross-sectional studies or case reports; the effectiveness of TCE therapies has not been fully assessed with a randomized control trial (RCT). In order to evaluate the combined clinical effectiveness of TCE for KOA, we conducted a systematic review and meta-analysis on the existing RCTs on KOA. ⋯ Compared with a control group; the synthesized data of TCE showed a significant improvement in WOMAC/KOOS pain score (SMD = -0.61; 95% CI: -0.86 to -0.37; p < 0.001), stiffness score (SMD = -0.75; 95% CI: -1.09 to -0.41; p < 0.001), and physical function score (SMD = -0.67; 95% CI: -0.82 to -0.53; p < 0.001). Conclusions: Our meta-analysis suggested that TCE may be effective in alleviating pain; relieving stiffness and improving the physical function for patients with KOA. Yet; given the methodological limitations of included RCTs in this meta-analysis; more high-quality RCTs with large sample size and long-term intervention are required to further confirm the effectiveness and underlying mechanisms of TCE for treating KOA.

Gender Effect on Political Leaders' Nonverbal Communicative Structure during the COVID-19 Crisis.
During the COVID-19 pandemic, there has been intense interest in political leaders' nonverbal communicative structures (NCS) during televised appearances. This study analyzes the effect of gender on leaders' NCS and presents theoretical and analytical frameworks of gendered NCS. We analyzed 20 televised appearances by 10 heads of state (five males and five females) from democratic Western countries during the COVID-19 pandemic. ⋯ Furthermore, the effect of gender on leaders' NCS had an interaction effect with the situation of the pandemic, indicating that countries with a female leader had fewer diseased and severe cases and more calmness and healing NCS. The conclusions present theoretical and analytical frameworks that explain the central effect of gender on contemporary leaders' NCS. This study develops advanced distinctive profiles for male versus female leaders' NCS of emotions, cognition, and behavior during a crisis.

Study on the Relationship between Leisure Activity Participation and Wearing a Mask among Koreans during COVID-19 Crisis: Using TPB Model.
This study utilizes the Theory of Planned Behavior (TPB) variables-including "attitude," "subjective norms," and "perceived behavioral control"-to understand the relationship between mask-wearing behavior and physical/non-physical leisure activity participation in Koreans as well as the tendencies behind mask-wearing intentions within leisure activities. The measurement tools used attitude, subjective norms, control, and mask use intention factors based on the TPB. Overall, 545 individuals participated, and the non-overlapping regions, sex, and age were considered through the stratified sampling method. ⋯ It was found that control influences the tendency of intention to wear a mask depending on whether the group was engaged in physical or non-physical activity. Therefore, it can be stated that mask-wearing must be mandatory during physical and non-physical activities owing to respiratory diseases such as COVID-19. It is also important to simultaneously promote a positive attitude toward mask-wearing to enable people to believe that they can stay in full control of their own health.

Association between Peak Expiratory Flow Rate and Exposure Level to Indoor PM2.5 in Asthmatic Children, Using Data from the Escort Intervention Study.
Various studies have indicated that particulate matter <2.5 μm (PM2.5) could cause adverse health effects on pulmonary functions in susceptible groups, especially asthmatic children. Although the impact of ambient PM2.5 on children's lower respiratory health has been well-established, information regarding the associations between indoor PM2.5 levels and respiratory symptoms in asthmatic children is relatively limited. This randomized, crossover intervention study was conducted among 26 asthmatic children's homes located in Incheon metropolitan city, Korea. ⋯ During a crossover intervention period of seven weeks, we observed that, in the filter-on group, indoor PM2.5 levels significantly decreased by up to 43%. (p < 0.001). We also found that the daily or weekly unit (1 μg/m3) increase in indoor PM2.5 levels could significantly decrease PEFR by 0.2% (95% confidence interval (CI) = 0.1 to 0.5) or PEFR by 1.2% (95% CI = 0.1 to 2.7) in asthmatic children, respectively. The use of in-home air filtration could be considered as an intervention strategy for indoor air quality control in asthmatic children's homes.
