The effects of swimming sports on the prevention and restoration of COVID-19 and its variant strains: A protocol for systematic review and meta-analysis.

INTRODUCTION: Since 2019, corona virus disease 2019 (COVID-19) has become a new round of "epidemic," which has brought about a major crisis to the world from national development, to people's life safety and mental health. Faced with the constant variation of viruses, from COVID-19 to Delta to Omicron. How to curb its further deterioration and enhance human defense against viruses is the focus of scientific researchers. From previous studies, we found that in addition to basic medical treatment, swimming with a certain amount of load and intensity can promote the ventilator of the human body, thereby playing an auxiliary and preventive role in the treatment of COVID-19 and its variant strains. METHODS: This study searched China knowledge network, Web of science, Google scholar, PubMed database to search for the relevant research on swimming prevention and treatment for COVID-19, and the deadline for searching was December 2021. Two researchers independently screened and extracted the literature, and evaluated the bias risk of the included studies. The methodological quality of the included literature was evaluated by the Chochrane bias risk assessment tool. RESULT: This study will provide new evidence for the prevention and recovery of COVID-19 and its variant strains by swimming. CONCLUSION: To provide a method to help the prevention and restoration of COVID-19 and its variant strains by swimming. INPLASY REGISTRATION NUMBER: INPLASY2021120075.

Management of acute coronary syndrome in the context of coronavirus disease 2019.

ABSTRACT: Coronavirus disease 2019 (COVID-19) is still developing worldwide. The prognosis of the disease will become worse and mortality will be even higher when it is combined with cardiovascular disease. Furthermore, COVID-19 is highly infectious and requires strict isolation measures. For acute coronary syndromes (ACS), a common cardiovascular disease, infection may aggravate the occurrence and development of ACS, making the management of more difficult. It will be an enormous challenge for clinical practice to deal with ACS in this setting of COVID-19.Aim to reduce the mortality of ACS patients during the epidemic of COVID-19 by standardizing procedures as much as possible.Pubmed and other relevant databases were searched to retrieve articles on COVID-19 and articles on ACS management strategies during previous influenza epidemics. The data was described and synthesized to summarize the diagnosis and management strategy of ACS, the preparation of catheter laboratory, and the protection of the medical staff in the context of COVID-19. Ethical approval is not required in this study, because it is a review with no recourse to patient identifiable information.Standardized diagnosis and treatment advice can help reduce the mortality of COVID-19 patients with ACS. In the absence of contraindications, the third generation of thrombolytic drugs should be the first choice for thrombolytic treatment in the isolation ward. For patients who have to receive PCI, this article provides detailed protective measures to avoid nosocomial infection.

Follow-up study of the pulmonary function and related physiological characteristics of COVID-19 survivors three months after recovery.

BACKGROUND: The long-term pulmonary function and related physiological characteristics of COVID-19 survivors have not been studied in depth, thus many aspects are not understood. METHODS: COVID-19 survivors were recruited for high resolution computed tomography (HRCT) of the thorax, lung function and serum levels of SARS-CoV-2 IgG antibody tests 3 months after discharge. The relationship between the clinical characteristics and the pulmonary function or CT scores were investigated. FINDINGS: Fifty-five recovered patients participated in this study. SARS-CoV-2 infection related symptoms were detected in 35 of them and different degrees of radiological abnormalities were detected in 39 patients. Urea nitrogen concentration at admission was associated with the presence of CT abnormalities (P = 0.046, OR 7.149, 95% CI 1.038 to 49.216). Lung function abnormalities were detected in 14 patients and the measurement of D-dimer levels at admission may be useful for prediction of impaired diffusion defect (P = 0.031, OR 1.066, 95% CI 1.006 to 1.129). Of all the subjects, 47 of 55 patients tested positive for SARS-CoV-2 IgG in serum, among which the generation of Immunoglobulin G (IgG) antibody in female patients was stronger than male patients in infection rehabilitation phase. INTERPRETATION: Radiological and physiological abnormalities were still found in a considerable proportion of COVID-19 survivors without critical cases 3 months after discharge. Higher level of D-dimer on admission could effectively predict impaired DLCO after 3 months discharge. It is necessary to follow up the COVID-19 patients to appropriately manage any persistent or emerging long-term sequelae.
