Purpose: During the COVID-19 pandemic, a significant number of measures were taken worldwide to limit the transmission of SARS-CoV-2, and in many ways, changed human life. All these measures had harmful consequences and impacted the well-being of many people. Children were one of the most vulnerable groups. We conducted the present study to assess children’s and staff’s well-being in French-speaking primary schools in Belgium during the COVID-19 pandemic. Methods: A 37-question questionnaire for each child based on the Revised Children’s Manifest Anxiety Scale (RCMAS), and a 14-question questionnaire for each staff based on the Hospital Anxiety and Depression (HAD) scale was undertaken in order to assess the well-being. Multiple logistic regressions were performed to assess the relationship between RCMAS or HAD and other explanatory variables. Staff reported their perception of their current life and their future life in 5 years on a Visual Analogue Scale (VAS). Results: A total of 231 children and 221 staff in 11 primary schools answered the well-being questionnaire between January and May 2021. 53% (122/231) of children had symptoms of anxiety. Girls reported more anxiety symptoms than boys (≥10: 59%;Adj OR = 2.25;95% CI [1.28;4.03]). 52% (120/231) of children had a definite state of social desirability. According to age, the youngest (6 - 7 years) children were more likely to have social desirability (≥5: 71%;Adj OR = 3.44;95% CI [1.53;8.09]) compared to the oldest (10 - 12 years). Children who did not practice outdoor/street activities were more likely to have social desirability (≥5: 60%;Adj OR = 2.59;95% CI [1.38;4.99]). In schools with a higher local incidence of SARS-CoV-2, children were more likely to have social desirability (≥5: 64%;Adj OR = 2.15;95% CI [1.13;4.17]). In schools with a lower socioeconomic status, children were more likely to have social desirability (≥5: 72%;Adj OR = 2.74;95% CI [1.23;6.37]). Higher RCMAS anxiety (r = −0.18;p −0.23;p −0.20;p Conclusion: Our results showed that the well-being of children was impacted during the COVID-19 pandemic. Special attention must be focused on the most vulnerable groups, as the consequences can be catastrophic in the long term. 展开更多

Backgrounds: Health does not only physical health, therefore, we need to study it from various viewpoints. Many Japanese female complain of a Hie or a low back pain (LBP), which they reduce their subjective well-being. We analyze. Those patients often have acupuncture therapy. In this study, we analyze the characteristics of Hie and LBP, the satisfaction level of alternative therapy and we pursue a tip to improve subjective well-being. Methods: Of 1000 women, Hie (+)/Hie (−) or LBP (+)/LBP (−), we compared their body temperature (BT) (axilla) and body mass index (BMI). Furthermore, the Chi test identified ten factors of “body” and seven “mind” information. Results: In the result of BT (axilla) while LBP indicated a significant difference. Both Hie and LBP showed difference in the opposite direction. Hie did now show such clear differences in “body” information. However, interestingly, all seven questions in the “mind” information showed statistical difference. Discussion and conclusion: One reason why those patients have acupuncture therapy may acupuncture therapy traditionally has not separate “mind” and “body” and it has the concept of “mind-body unity”. To improve subjective well-being, first we need to focus on “Mind” as well as “mind-body unity”. Mental-health support is important for patients with Hie or LBP to reduce physiological stress. 展开更多

The Quarter-Horses regularly participate in non-traditional sports that simulate activities on cattle ranches. In the vaquejada races, the horses run at about 30 km/h, reaching maximum heart rates of around 200 bpm, indicating the great physical effort during competitions and with that could impact welfare. To test the hypothesis that vaquejada horses can be evaluated for the quality of welfare through a combination of non-invasive and invasive methods, an experiment was developed that aimed to assess the quality of welfare through thermography and blood biomarkers before and after vaquejada races. Ten vaquejada horses, which were in regular competition, were submitted to the vaquejadas racing test were used. Thermography was performed in 14 regions of interest (head, neck and thorax) in the following phases: pre-race and +1, +4 and +24 hours of the races. Blood samples were collected in pre-race, immediately after and +1, +4 and +24 hours of the races. Results were submitted to ANOVA and Tukey’s test, with p set at 5%. Thermography showed that local temperatures before the race and +24 hours after the races were similar (p > 0.05), as well as between +1 and +4 hours after the races (p > 0.05), which showed higher surface temperatures than the first group (pre-race and +24 hours) (p 0.05) after the exercises. In conclusion, the vaquejada horses evaluated by infrared thermography and blood analyses maintained the quality of well-being, with the physiological elevation of several parameters after the races and recovery in less than 24 hours after the races. Thermographic images were also able to help in the analysis of the regions of interest that have contact with harnesses, demonstrating that the use of adequate and correct equipment does not compromise animal welfare. 展开更多

This study aimed to alert people that the harmony between human beings and nature has already become an urgent problem. All people are responsible for maintaining the harmony, which is the also the inexorable trend of historical development. Reviewing the evolution history of human kind, the relationship between human beings and nature from harmony to imbalance, from imbalance to a new harmony was analyzed from the macro perspective, and it was pointed out that the present society is in the transitional phase from imbalance to a new harmony and also a phase that people are consciously coordinating their relationship with nature. It was found through the study that a harmonious society relies on the harmony between human beings and nature, and the latter is a necessary condition for a real harmonious society, however, people always forget such a principle. The imbalanced relationship between human beings and nature has seriously influenced many aspects of social harmony, and become instable factors in China and international society, even threatened the development and survival of human beings. Thus, all people should make joint efforts in creating win-win conditions for the development between human beings and nature, and ensuring offspring a healthy and green earth. 展开更多

Objective: To examine the relationship between emotional well-being, patient activation and social support in a cohort of adults with severe obesity who underwent gastric bypass surgery from January to December 2012. Design: Cross-sectional survey. Subjects: Of a total population of 129 people, aged 18 - 68 years, at a local hospital in central Norway, 64 (50%) responding to the questionnaire, 52 (81%) being women. Main Outcome Measures: The World Health Organization—Five Well-Being Index (WHO-5), the 13-item Patient Activation Measure (PAM-13), a 16-item instrument on the frequency and content of social support, and demographic and clinical data. Results: A significant positive association was found between higher level of patient activation and better emotional well-being (P = 0.02) in linear regression analysis. A higher level of family support was significantly associated with better emotional well-being (practical social support from the family (P = 0.04), emotional social support from family (P = 0.01) and from friends (P = 0.005)). Conclusion: Screening tools for emotional well-being should be used systematically in postoperative consultations to recognize those who need a more individually tailored post-surgery follow-up care after gastric bypass surgery. In addition, health care providers in both specialist and primary health care settings should consider assessing the level of social support as part of regular follow-up routines. 展开更多
