ABSTRACT
Severe acute respiratory syndrome coronavirus (SARS-CoV-2) causes environmental contamination via respiratory droplets and persists on contaminants and environmental surfaces for anywhere from a few hours to 6 days. Therefore, it is particularly important to understand the transmission and containment of SARS-CoV-2 on the surface of objects within isolated environments. In this study, 356 environmental surface samples were collected and 79 tested positive, with the highest contamination rate (56.96%) in the wood category (bedside tables, wood floors, and walls). This study revealed differences in the detection rates of environmental surfaces in hospitalized and discharged rooms of patients with confirmed COVID-19 in 2 isolated settings (A: p = 0.001;B: p = 0.505) and suggested that environmental contamination may be an important route of virus transmission, providing a reference to guide the enhancement of ventilation, the use of hotel isolation model, the advocacy of cotton masks, and the effective suppression of virus transmission.
ABSTRACT
PURPOSE: To evaluate the quality of systematic reviews/meta-analyses (SR/MAs) on alternative exercise traditions in cancer care. METHODS: PubMed, Cochrane Library, Web of Science, Ovid, EBSCOhost, WanFang Database, China National Knowledge Infrastructure, and VIP Database were searched from their inception to June 30, 2020. The search used a combination of subject words and free words. The search terms included "Tai Chi," "Qigong," "Baduanjin," "Yoga," "Pilates," "Cancer," "Meta-analysis," and "Systematic review." Two researchers independently performed literature screening and data extraction and used AMSTAR scale and PRISMA statement to evaluate the methodology and the quality of the evidence. RESULTS: A total of 26 SR/MAs were included. The AMSTAR scale score was 5-10 points, with an average of 7.46±1.33 points. Overall, the methodological quality was considered to be moderate. The PRISMA list score was 13-24 points, with an average of 19.19±2.86 points. Among the papers evaluated, eight reports were relatively complete. A total of 15 papers indicated certain defects. A total of three papers showed relatively serious information defects. CONCLUSION: Relative to the control group, alternative exercise traditions may be effective in improving the quality of life, anxiety, depression, distress, and fatigue of cancer patients. However, they may not necessarily improve patients' sleep outcome, body mass index, and pain. During convalescence, cancer patients can be encouraged to start engaging in physical exercise, and professionals can develop appropriate exercise alternatives to ensure the expected effect of exercise while ensuring the safety of patients. The methodological quality of the systematic evaluations of the intervention effects of alternative exercise traditions on cancer patients is not satisfactory. Hence, focus should be directed to the improvement of the preliminary design scheme, publication status, literature retrieval, conflict of interest, and other aspects.
