ABSTRACT
Moxibustion has been widely used in the prevention and treatment of COVID-19. However, there is no systematic review of current topics and clinical findings on moxibustion for COVID-19. We conducted this scoping review to systematically summarize and analyze the themes and findings of published articles, and to provide an overview of current knowledge and practice of moxibustion for COVID-19.Methods:: PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, SinoMed, Wan Fang Data, and VIP databases were searched from inception until April 2022. The relevant data were presented through bar graphs, structured tables, and figures along with descriptive statistics and analysis. This scoping review was conducted based on the PRISMA-ScR Checklist. Results:: A total of 76 articles were reviewed: 47 reviews, 19 clinical research studies, seven systematic reviews (all were protocols), and three guidelines. All the studies were conducted by Chinese researchers and published from January 1, 2020 to March 14, 2022. The feasibility of moxibustion in the prevention and treatment of mild or moderate COVID-19 is based on the consensus of therapeutic mechanisms and effectiveness. The most adopted approach was the suspended and gentle moxibustion, and the most frequently applied or recommended acupoints were found to be ST36, CV8, CV6, CV4, CV12, GV14, BL13, LI4, ST25, and LR3. Conclusions:: As a convenient and safe traditional Chinese medicine (TCM) therapy with its specific feature, moxibustion has been significantly effective at ameliorating mild or moderate symptoms among COVID-19 patients. Further large-scale, well-designed research and international cooperation are still warranted in clinical evaluations of moxibustion. Graphical :: http://links.lww.com/AHM/A35.
ABSTRACT
Since face masks may help slow the spread of diseases, a patient may wear a face mask for an MRI exam during the COVID-19 pandemic. However, metal parts, like nose or face clips within the mask, may burn the patient during an MRI. In this numerical study, we investigated the two-channel RF shimming effect on the RF-induced local SAR of a face mask with a metal strip. With the parallel transmission RF field exposure to the virtual adult male model with a face mask, the RF-induced local SAR1g is calculated for each excitation condition. Under the exposure limit of a whole-body averaged SAR of 2 W/kg and head averaged SAR of 3.2 W/kg, the peak SAR1g is 178 W/kg and 62 W/kg occurs at the nose touching the metal strip. The SAR1g value is higher on the skin area close to the metal strip than at other locations. The metal strip within the face mask could cause a potential RF-induced heating hazard. © 2022 IEEE.
ABSTRACT
Purpose Due to the fact that most employees have been forced to work remotely during the lockdown resulting from the COVID-19 pandemic, there is great concern about how to alleviate increased stress among employees through human resource (HR) practices. Drawing upon the job demands-control (JDC) model and the job demands-resources (JDR) model, this study empirically investigated the direct effect of HR practices on employee stress in enforced remote work and the mediating role of sources of stress (SoS) and sense of control (SoC). Design/methodology/approach Data were collected through an online survey platform called Wenjuanxing from March 15 to 22, 2020 in Hubei, China and from April 22 to 29, 2022 in Shanghai, China. Respondents scanned the QR code on WeChat to enter the platform. A total of 511 valid questionnaires were received with a response rate of 75.4%. After controlling demographic variables, the authors used the mediation modeling and PROCESS tool to test the proposed hypotheses. Findings HR practices negatively affect stress in enforced remote work among employees. Both SoS and SoC partially mediate the relationship between HR practices and stress. HR practices can alleviate stress via decreasing SoS and enhancing SoC, respectively. Moreover, employee care and training are found to be two key factors of HR practices to help employees alleviate stress in enforced remote work. Originality/value Lockdown as an extreme external condition has brought great challenges in employee work arrangement as well as HR practices. Although the relationship between HR practices and job stress was studied previously, there is a lack of research on the effects of HR practices on stress in enforced remote work due to lockdown. It advances knowledge on HR practices' stress-reducing effect in the context of remote work and provides suggestions for HR practitioners on ways of alleviating employee stress in remote work.
ABSTRACT
As an important immuneoactive component in eggs, yolk immunoglobulin (IgY) shows great competitiveness in research and production due to its good stability, high safety, low cost, easy availability, strong immune activity, and no drug resistance. This article highlights the significant advantages of IgY as a good antibiotic substitute in the prevention and treatment of viral and bacterial diseases. Also, IgY has great potential in the regulation of nutrient metabolism balance, intestinal microflora and immune homeostasis by affecting key rate-limiting enzymes, and relevant receptors and inflammatory factors specifically. Proper diet and targeted delivery of foodborne IgY may be a new perspective on inflammation regulation, disease control, nutritional balance or homeostasis, and oral microencapsulated IgY is expected to be a new approach against increasing public health emergencies (such as COVID-19 pandemic). © 2022, China Food Publishing Company.
