简介：摘要Coronavirus disease (COVID-19), the infection caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported on December 31, 2019. Because it has only been studied for just over three months, our understanding of this disease is still incomplete, particularly regarding its sequelae and long-term outcomes. Moreover, very little has been written about the rehabilitation needs of patients with COVID-19 after discharge from acute care. The objective of this report is to answer the question " What rehabilitation services do survivors of COVID-19 require？" The question was asked within the context of a subacute hospital delivering geriatric inpatient and outpatient rehabilitation services. Three areas relevant to rehabilitation after COVID-19 were identified. First, details of how patients may present have been summarized, including comorbidities, complications from an intensive care unit stay with or without intubation, and the effects of the virus on multiple body systems, including those pertaining to cardiac, neurological, cognitive, and mental health. Second, I have suggested procedures regarding the design of inpatient rehabilitation units for COVID-19 survivors, staffing issues, and considerations for outpatient rehabilitation. Third, guidelines for rehabilitation (physiotherapy, occupational therapy, speech-language pathology) following COVID-19 have been proposed with respect to recovery of the respiratory system as well as recovery of mobility and function. A thorough assessment and an individualized, progressive treatment plan which focuses on function, disability, and return to participation in society will help each patient to maximize their function and quality of life. Careful consideration of the rehabilitation environment will ensure that all patients recover as completely as possible.

简介：AbstractCoronavirus disease 2019 (COVID-19) is a newly emerged infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The number of COVID-19 cases is continuously increasing and no effective drugs or vaccines are currently available. Accurate and efficient diagnostic testing methods are desperately needed for the detection of SARS-CoV-2 and antiviral antibodies in infected individuals. Various assay techniques, including nucleic acid tests [eg, polymerase chain reaction (PCR), reverse transcription-PCR, real-time loop-mediated isothermal amplification, and CRISPR-Cas-based detection], serological tests [eg, immunoglobulin (Ig)A, IgM/G], imaging tests (eg, computed tomography and positron-emission tomography), and nanoparticle-based detections have been reported for COVID-19 diagnosis. This review aims to present the current diagnostic tools for SARS-CoV-2 and their performance characteristics to inform the appropriate selection of diagnostic and surveillance technologies at optimal testing times. We also describe the advantages of detection using combined nucleic acid and imaging tests, or serological testing and point-of-care diagnostics. Developing reliable protein biomarkers targeting the conserved proteins of SARS-CoV-2 rather than IgA, IgM, or IgG would be useful to manage SARS-CoV-2.

简介：AbstractIntroduction:The transmission pathways of coronavirus disease 2019 (COVID-19) remain not completely clear. In this case study the test for the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pharyngeal swab and anal swab were compared.Case presentation:A 3-month-old girl was admitted to our hospital with COVID-19. Her parents had both been diagnosed with COVID-19. The results of pharyngeal swab and anal swab of the little girl were recorded and compared during the course of the disease. The oropharyngeal specimen showed negative result for SARS-CoV-2 on the 14th day after onset of the illness. However, the anal swab was still positive for SARS-CoV-2 on the 28th day after the onset of the illness.Conclusion:The possibility of fecal-oral transmission of COVID-19 should be assessed. Personal hygiene during home quarantine merits considerable attention.

简介：摘要BACKGROUNDCoronavirus disease 2019 (COVID-19) caused by a new Betacoronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is currently a global pandemic. Gathered clinicopathological evidence in COVID-19 patients shows that alveoli injuries and interstitial changes are the major mechanisms of impaired O2/CO2 exchange. Few rehabilitation exercises concerning COVID-19 patients were reported. Here, we present a modified version of rehabilitation exercises based on the underlying mechanism of the disease to mild cases of COVID-19. These exercises aimed to improve the pulmonary function of patients and ease the expectoration process. Additionally, an essential branch of Traditional Chinese Medicine (TCM) named acupressure was integrated into the exercises to facilitate the recovery and maintenance of pulmonary function.METHODSFrom March 4, 2020 to May 5, 2020, a total of 60 COVID-19 patients who completed the full course of MRE were enrolled in this observational study. The diagnostic and classification criteria were based on the 7th edition of Diagnosis and Treatment Guideline of COVID-19 published by the National Health Commission of the People′s Republic of China. We prospectively gathered patients′ reported outcomes concerning respiration-related symptoms at four different time points, including: (I) at admission; (II) at the time of hospital discharge; (III) two weeks after discharge; (IV) four weeks after discharge. The reported respiratory symptoms included dry cough, productive cough, difficulty in expectoration, and dyspnea.RESULTSIn total, 60 confirmed mild COVID-19 cases were enrolled with a median age of 54 years old. The baseline prevalence for dry cough, productive cough, difficulty in expectoration, and dyspnea were 41.7%, 43.3%, 35.0%, and 50.0%, respectively. The pronounced decline in symptom prevalence was recorded over time. Interestingly, four weeks after discharge, we noticed a lower remission rate in productive cough and difficulty in expectoration.CONCLUSIONThe modified rehabilitation exercises were retrieved from the Eight-Section Brocade, and are specifically designed for rehabilitation of COVID-19 patients at home or health facilities. Based on current findings on pronouncedly improved remission rate in respiratory symptoms, we recommend the MRE as suitable rehabilitation exercise to smooth respiration and ease the expectoration process in mild COVID-19 cases.

简介：摘要This analysis extrapolates information from prior studies and experiences to bring PM&R perspective and intervention to the multidisciplinary treatment of COVID-19. The purpose of pulmonary rehabilitation in COVID-19 patients is to improve symptoms of dyspnea, relieve anxiety, reduce complications, minimize disability, preserve function and improve quality of life. Pulmonary rehabilitation during the acute management of COVID-19 should be considered when possible and safe and may include nutrition, airway, posture, clearance technique, oxygen supplementation, breathing exercises, stretching, manual therapy, and physical activity. Given the possibility of long-term disability, outpatient post-hospitalization pulmonary rehabilitation may be considered in all patients hospitalized with COVID-19.

简介：摘要The COVID-19 pandemic affects a large number of patients with a rapid progression of respiratory failure often requiring hospitalization or intensive care unit treatment in some patients. Survivors of severe COVID-19 suffer from persistent weakness and cardiorespiratory failure. Feasibility and potential benefit of cardiopulmonary rehabilitation (CR) after COVID-19 remains unclear. Therefore, we retrospectively analyzed a cohort of COVID-19 patients in a single center inpatient rehabilitation clinic and describe performance and outcome during CR.Patients were referred from acute care hospitals for rehabilitation after severe COVID-19. The cohort (n＝28) was divided in ventilated or not ventilated patients for further analysis. 50% were female, mean age was 66 years and patients stayed in the acute hospital for 19.3±10.7 days before referral for CR. 17 patients (61%) needed previous ICU treatment in the acute care hospital. Risk factors, assessments and questionnaires on admission were comparable in both groups. Significant enhancements were observed in 6-minute walking test and Feeling Thermometer which were independent of previous ventilation status.In conclusion, comprehensive CR following COVID-19 is safe, feasible and effective. Improvements in physical performance and subjective health status were independent of previous ventilation.

简介：AbstractThis study aimed to determine the clinical characteristics of patients diagnosed with the coronavirus disease 2019 (COVID-19). Clinical data of COVID-19 patients diagnosed between January 28, 2020 and February 23, 2020 at the Beijing You'an Hospital were summarized and analyzed. Overall, 45 (18 men and 27 women) patients were included in this study. The average age of patients was 58 years (range, 7–94 years). Furthermore, 21 patients (47%) experienced underlying chronic diseases, with another four patients (9%) having three or more chronic diseases simultaneously. The first symptoms appeared at the onset of illness onset include fever in 36 patients (80%), cough in 23 patients (51%), and expectoration in 15 patients (33%), respectively. Patients may experience hepatic and renal injury as well as abnormal myocardial enzymes in varying degrees. Senior patients (≥58) and accompanying chronic diseases were considered as independent predictors for developing a severe and critically ill population with increased mortality. Laboratory results regarding the NEU percentage, NLR, ALC, and C-reactive protein levels were considered significant in predicting clinically critical disease or for prognosis assessment and thus require further studies. COVID-19 may affect multiple organs of the human body. Glucocorticoid is considered effective in the treatment of patients diagnosed with severe COVID-19.
