简介：摘要As a highly infectious respiratory tract disease, coronavirus disease 2019 (COVID-19) can cause respiratory, physical, and psychological dysfunction in patients. Therefore, pulmonary rehabilitation is crucial for both admitted and discharged patients of COVID-19. In this study, based on the newly released pulmonary rehabilitation guidelines for patients with COVID-19, as well as evidence from the pulmonary rehabilitation of patients with severe acute respiratory syndrome, we investigated pulmonary rehabilitation for patients with COVID-19 having complications, such as chronic pulmonary disease, and established an intelligent respiratory rehabilitation model for these patients.

简介：摘要After severe COVID-19 disease, many patients will experience a variety of problems with normal functioning and will require rehabilitation services to overcome these problems. The principles of and evidence on rehabilitation will allow an effective response. These include a simple screening process; use of a multidisciplinary expert team; four evidence-based classes of intervention (exercise, practice, psychosocial support, and education particularly about self-management); and a range of tailored interventions for other problems. The large number of COVID-19 patients needing rehabilitation coupled with the backlog remaining from the crisis will challenge existing services. The principles underpinning vital service reconfigurations needed are discussed.

简介：摘要The global outbreak of coronavirus disease 2019 has created an unprecedented challenge to the society. Currently, the United States stands as the most affected country, and the entire healthcare system is affected, from emergency department, intensive care unit, postacute care, outpatient, to home care. Considering the debility, neurological, pulmonary, neuromuscular, and cognitive complications, rehabilitation professionals can play an important role in the recovery process for individuals with coronavirus disease 2019. Clinicians across the nation′s rehabilitation system have already begun working to initiate intensive care unit-based rehabilitation care and develop programs, settings, and specialized care to meet the short- and long-term needs of these individuals. We describe the anticipated rehabilitation demands and the strategies to meet the needs of this population. The complications from coronavirus disease 2019 can be reduced by (1) delivering interdisciplinary rehabilitation that is initiated early and continued throughout the acute hospital stay, (2) providing patient/family education for self-care after discharge from inpatient rehabilitation at either acute or subacute settings, and (3) continuing rehabilitation care in the outpatient setting and at home through ongoing therapy either in-person or via telehealth.

简介：摘要目的新型冠状病毒肺炎(COVID-19)是由引起严重急性呼吸综合征的2019新型冠状病毒(2019-nCoV)导致的全球流行性疾病，能否为COVID-19的危重患者进行探索性、抢救性的肺移植手术在移植学界引起了广泛讨论。到目前为止国内有报道COVID-19危重患者接受了肺移植，对于这类探索性、抢救性肺移植手术，移植术后相关治疗及预后情况尚无结论。本文主要从相关肺移植与病毒感染指南、肺移植适应证、术后并发症、伦理、卫生经济学等方面阐述这一争论，并思考COVID-19肺移植手术在未来的发展方向。

简介：摘要突如其来的新型冠状病毒肺炎（COVID-19）大暴发尽管在我国已经被控制，但仍在全世界暴发和流行，死亡人数仍在不断增加。绝大多数的COVID-19确实是以肺部不同程度损伤为主，也是导致死亡的最主要原因，但是各个临床学科都在关注本系统是否有重要的受损现象。神经内科同行更关注COVID-19是否直接或间接地累及神经系统。从我国8万多个病例看，所报道的资料中，真正并发神经系统受损的客观证据不多。而欧美自COVID-19大流行以来，报道了一些合并周围神经受累病例，值得同行们关注。

简介：摘要BACKGROUNDDifferent degrees of disorders are reported in respiratory function, physical function and psychological function in patients with corona virus disease 2019 (COVID-19), especially in elderly patients. With the experience of improved and discharged COVID-19 patients, timely respiratory rehabilitation intervention may improve prognosis, maximize functional preservation and improve quality of life (QoL), but there lacks of studies worldwide exploring the outcome of this intervention.OBJECTIVETo investigate the effects of 6-week respiratory rehabilitation training on respiratory function, QoL, mobility and psychological function in elderly patients with COVID-19.METHODSThis paper reported the findings of an observational, prospective, quasi-experimental study, which totally recruited 72 participants, of which 36 patients underwent respiratory rehabilitation and the rest without any rehabilitation intervention. The following outcomes were measured: pulmonary function tests including plethysmography and diffusing lung capacity for carbon monoxide (DLCO), functional tests (6-min walk distance test), Quality of life (QoL) assessments (SF-36 scores), activities of daily living (Functional Independence Measure, FIM scores), and mental status tests (SAS anxiety and SDS depression scores)．RESULTSAfter 6 weeks of respiratory rehabilitation in the intervention group, there disclosed significant differences in FEV1(L), FVC(L), FEV1/FVC%, DLCO% and 6-min walk test. The SF-36 scores, in 8 dimensions, were statistically significant within the intervention group and between the two groups. SAS and SDS scores in the intervention group decreased after the intervention, but only anxiety had significant statistical significance within and between the two groups.CONCLUSIONSSix-week respiratory rehabilitation can improve respiratory function, QoL and anxiety of elderly patients with COVID-19, but it has little significant improvement on depression in the elderly.

简介：AbstractBackground:The outbreak of coronavirus disease 2019 (COVID-19) has become a pandemic causing global health problem. We provide estimates of the daily trend in the size of the epidemic in Wuhan based on detailed information of 10 940 confirmed cases outside Hubei province.Methods:In this modelling study, we first estimate the epidemic size in Wuhan from 10 January to 5 April 2020 with a newly proposed model, based on the confirmed cases outside Hubei province that left Wuhan by 23 January 2020 retrieved from official websites of provincial and municipal health commissions. Since some confirmed cases have no information on whether they visited Wuhan before, we adjust for these missing values. We then calculate the reporting rate in Wuhan from 20 January to 5 April 2020. Finally, we estimate the date when the first infected case occurred in Wuhan.Results:We estimate the number of cases that should be reported in Wuhan by 10 January 2020, as 3229 (95% confidence interval [CI]: 3139–3321) and 51 273 (95% CI: 49 844–52 734) by 5 April 2020. The reporting rate has grown rapidly from 1.5% (95% CI: 1.5–1.6%) on 20 January 2020, to 39.1% (95% CI: 38.0–40.2%) on 11 February 2020, and increased to 71.4% (95% CI: 69.4–73.4%) on 13 February 2020, and reaches 97.6% (95% CI: 94.8–100.3%) on 5 April 2020. The date of first infection is estimated as 30 November 2019.Conclusions:In the early stage of COVID-19 outbreak, the testing capacity of Wuhan was insufficient. Clinical diagnosis could be a good complement to the method of confirmation at that time. The reporting rate is very close to 100% now and there are very few cases since 17 March 2020, which might suggest that Wuhan is able to accommodate all patients and the epidemic has been controlled.

简介：摘要The present global pandemic of COVID-19 has brought the whole world to a standstill, causing morbidity, death, and changes in personal roles. The more common causes of morbidity and death in these patients include pneumonia and respiratory failure, which cause the patients to require artificial ventilation and other techniques that can improve respiratory function. One of these techniques is chest physiotherapy, and this has been shown to improve gas exchange, reverse pathological progression, and reduce or avoid the need for artificial ventilation when it is provided very early in other respiratory conditions. For patients with COVID-19, there is limited evidence on its effect, especially in the acute stage and in patients on ventilators. In contrast, in patients after discharge, chest physiotherapy in the form of respiratory muscle training, cough exercise, diaphragmatic training, stretching exercise, and home exercise have resulted in improved FEV1 (L), FVC (L), FEV1/FVC%, diffusing lung capacity for carbon monoxide (DLCO%), endurance, and quality of life, and a reduction in anxiety and depression symptoms. However, there are still controversies on whether chest physiotherapy can disperse aerosols and accelerate the rate of spread of the infection, especially since COVID-19 is highly contagious. While some authors believe it is possible, others believe the aerosol generated by chest physiotherapy is not within respirable range. Therefore, measures such as the use of surgical masks, tele-rehabilitation, and self-management tools can be used to limit cross-infection.

简介：AbstractImportance:Within the coronavirus disease 2019 (COVID-19) global pandemic, more attention is warranted for whether this new infectious disease has unique manifestations in children.Objective:To retrospectively determine the epidemiological and clinical characteristics of 35 children with COVID-19 in Beijing, China.Methods:We collected data for 35 children diagnosed with COVID-19 who were admitted to Beijing Ditan Hospital from January 2020 to June 2020, and analyzed their epidemiological characteristics, clinical manifestations, laboratory examinations, chest imaging findings, treatments, and outcomes.Results:The children comprised 18 boys (51.4%) and 17 girls (48.6%) aged 6 months to 15 years. All patients had clear epidemiological history, with family clusters accounting for 28 cases (80.0%) and clear tracing of exposure to high epidemic areas in the remaining 7 cases (20.0%). Four (11.4%) patients were classified as asymptomatic, 17 (48.6%) as acute upper respiratory infection, and 14 (40.0%) as mild pneumonia, with no severe or critical cases. Clinical manifestations were mild, including fever in 18 (51.4%), cough in 14 (40.0%), and nausea and diarrhea in 7 (20.0%) patients. White blood cell count was mostly normal (26 cases, 74.3%) or decreased (7 cases, 20.0%); lymphocyte percentage was increased in 24 (68.7%); neutrophil percentage was decreased in 25 (71.4%); alanine aminotransferase was increased in 3 (8.6%); and serum potassium was decreased in 4 (11.4%). Time to negative viral nucleic acid testing was 2-42 days (mean: 14.0 ± 9.4 days). Chest imaging examination revealed that 20 patients (57.1%) had different forms of lung inflammation. Treatment was mainly isolation and nutritional support. Eleven patients were treated with interferon atomization inhalation. No patients required oxygen therapy. All 35 children were cured and discharged. Length of hospital stay was 9-54 days (mean: 25.4 ± 13.8 days). During regular follow-up after discharge, 5 children showed positivity again in the viral nucleic acid test and were re-hospitalized for observation and treatment. The mean length of re-hospitalization stay was 10.8 days.Interpretation:Children with COVID-19 mainly become infected within their family, and children of all ages are generally susceptible. The disease in children is mostly mild and the prognosis is good. Nucleic acid tests in some patients become positive again after discharge, suggesting that it is of great significance to carry out centralized isolation medical observations and active nucleic acid tests in close contacts for early detection of patients and routine epidemic prevention and control.

简介：AbstractEffective prophylactic and therapeutic interventions are urgentlyneeded to address the coronavirus disease 2019 (COVID-19) pandemic. Various antiviral drugs have recently been tested. Type I interferon (IFN) is a regulatory protein involved in the innate immune response, with broad-spectrum antiviral activities and the ability to directly block viral replication and support the immune response to eliminate virus infection. Insufficient virus-induced type I IFN production is characteristic of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, because SARS-CoV-2 suppresses the IFN response by interacting with essential IFN signaling pathways. Exogenous type I IFN is recommended for treating COVID-19. Unexpectedly however, angiotensin converting enzyme-2 (ACE2) receptor, which acts as a SARS-CoV-2 receptor, was shown to be stimulated by IFN, raising doubts about the suitability of IFN use. However, further studies have excluded concerns regarding IFN administration. Type I IFNs, including IFN-α1b, have been used clinically as antiviral drugs for many years and have shown strong antiviral activity against SARS-CoV-2 in vitro. Preliminary clinical studies of type I IFNs, especially when delivered via aerosol inhalation, have demonstrated efficacy for the treatment and prevention of COVID-19. Randomized controlled trials of IFN for COVID-19 treatment are ongoing.

简介：摘要BACKGROUNDCorona Virus Disease-2019 (COVID-19) pandemic is quickly spreading, putting under heavy stress health systems worldwide and especially Intensive Care Units (ICU). Rehabilitation Units have a crucial role in reducing disability in order to reintroduce patients in the community.OBJECTIVETo characterize pulmonary function and disability status and to propose an early rehabilitation protocol in a cohort of post-acute COVID-19 patients admitted to an Italian Rehabilitation Unit.METHODSDemographic, anamnestic and clinical characteristics, laboratory exams and medical imaging findings were collected for the entire cohort. Outcome measures evaluated at the admission in Rehabilitation Unit were: type of respiratory supports needed, fraction of inspired oxygen (FIO2), partial pressure of oxygen (PaO2), FIO2/PaO2, Barthel Index (BI), modified Medical Research Council (mMRC) Dyspnoea Scale, and 6-Minute Walking Test (6-MWT). Furthermore, we proposed an early rehabilitation protocol for COVID-19 patients based on baseline FiO2.RESULTSWe included 32 post-acute COVID-19 patients (22 male and 10 female), mean aged 72.6±10.9 years. BI was 45.2±27.6, with patients in need of higher FIO2 (≥ 40%) showing lower values: 39.6±25.7 vs 53.3±29.3. All patients had grade 4 or 5 on the mMRC Dyspnoea Scale. Only 14 COVID-19 patients were able to walk (43.7%). 6-MWT was feasible in 6 (18.8%) patients with a mean distance of 45.0±100.6 meters.CONCLUSIONSTaken together, our findings suggest that post-acute COVID-19 patients suffered from dyspnoea and shortness of breath even for minimal activities, with a resulting severe disability, and only a few of them were able to perform 6-MWT with poor results. An early rehabilitation protocol was proposed according to the baseline conditions of the patients.

简介：摘要A global pandemic of a new highly contagious disease called COVID-19 resulting from coronavirus (severe acute respiratory syndrome (SARS)-Cov-2) infection was declared in February 2020. Though primarily transmitted through the respiratory system, other organ systems in the body can be affected. Twenty percent of those affected require hospitalization with mechanical ventilation in severe cases. About half of the disease survivors have residual functional deficits that require multidisciplinary specialist rehabilitation. The workforce to deliver the required rehabilitation input is beyond the capacity of existing community services. Strict medical follow-up guidelines to monitor these patients mandate scheduled reviews within 12 weeks post discharge. Due to the restricted timeframe for these events to occur, existing care pathway are unlikely to be able to meet the demand. An innovative integrated post-discharge care pathway to facilitate follow up by acute medical teams (respiratory and intensive care) and a specialist multidisciplinary rehabilitation team is hereby proposed. Such a pathway will enable the monitoring and provision of comprehensive medical assessments and multidisciplinary rehabilitation. This paper proposes that a model of tele-rehabilitation is integrated within the pathway by using digital communication technology to offer quick remote assessment and efficient therapy delivery to these patients. Tele-rehabilitation offers a quick and effective option to respond to the specialist rehabilitation needs of COVID-19 survivors following hospital discharge.
