Acute myopericarditis and left shoulder capsulitis following second dose of mRNA SARS-CoV-2 Moderna vaccination.

Vaccination against mRNA SARS-CoV-2 has been administered on a very large scale and various side effects have been described. The increased risk of myopericarditis is known, and only a few cases of shoulder capsulitis have been reported after vaccination. These two pathologies have never been reported in the same patient after vaccination. Our article presents the history of a man in his 40s who presented with myopericarditis a few days after vaccination against SARS-CoV-2 with mRNA(Messenger RNA) Moderna® vaccine and who at the same time developed shoulder capsulitis. His cardiovascular symptoms resolved rapidly, and his shoulder symptoms improved/resolved within 1 year. This case should make physicians aware of the possibility of several concomitant side effects following vaccination against SARS-CoV-2.

Sensory training system for use at home by people with complex regional pain syndrome in England: protocol for a proof-of-concept study.

INTRODUCTION: Complex regional pain syndrome (CRPS) is a disabling and distressing chronic pain condition characterised by a range of sensory, motor, autonomic and trophic symptoms. UK guidelines recommend therapy interventions to help normalise touch perception through self-administered tactile and thermal desensitisation activities. Interventions have been developed, aiming to help individuals broaden their sensory experience, thereby relieving chronic pain. However, therapy-led interventions often experience practical constraints and poor adherence. In response, a sensory training system (STS) device has been designed for unsupervised independent home-use. METHODS: This proof-of-concept study aims to explore whether people with CRPS use the device at home for 30 minutes a day for 30 days. Secondary aims are to determine whether the STS device will change tactile acuity and perceived levels of pain intensity, pain interference, sensitivity or feelings towards the affected limb. We will seek to recruit 20 eligible participants. Participants will be asked to measure tactile acuity using a two-point discrimination assessment, complete an online questionnaire before and after use of the device and complete a daily diary. On completion of the 30-day use, participants will be invited to take part in a semi-structured interview to explore their experiences of using the device. ANALYSIS: Pain intensity and pain interference will be scored using the online Assessment Center Scoring Service or using the look-up table in the PROMIS scoring manual. The remaining questionnaire data, including tactile acuity results, and device-use data, including frequency and duration of use, will be analysed using descriptive statistics. Qualitative data will be thematically analysed. ETHICS AND DISSEMINATION: London-Stanmore Research Ethics Committee provided a favourable opinion on 19 April 2021 (ref 21/LO/0200). The NHS Health Research Authority, UK, approved this study on 7 June 2021. Dissemination will include peer-reviewed publications, presentations at conferences, social media and reports to the funder and patient charities. TRIAL REGISTRATION NUMBER: ISRCTN89099843.

Rehabilitation post-COVID-19: cross-sectional observations using the Stanford Hall remote assessment tool.

INTRODUCTION: The multisystem COVID-19 can cause prolonged symptoms requiring rehabilitation. This study describes the creation of a remote COVID-19 rehabilitation assessment tool to allow timely triage, assessment and management. It hypotheses those with post-COVID-19 syndrome, potentially without laboratory confirmation and irrespective of initial disease severity, will have significant rehabilitation needs. METHODS: Cross-sectional study of consecutive patients referred by general practitioners (April-November 2020). Primary outcomes were presence/absence of anticipated sequelae. Binary logistic regression was used to test association between acute presentation and post-COVID-19 symptomatology. RESULTS: 155 patients (n=127 men, n=28 women, median age 39 years, median 13 weeks post-illness) were assessed using the tool. Acute symptoms were most commonly shortness of breath (SOB) (74.2%), fever (73.5%), fatigue (70.3%) and cough (64.5%); and post-acutely, SOB (76.7%), fatigue (70.3%), cough (57.4%) and anxiety/mood disturbance (39.4%). Individuals with a confirmed diagnosis of COVID-19 were 69% and 63% less likely to have anxiety/mood disturbance and pain, respectively, at 3 months. CONCLUSIONS: Rehabilitation assessment should be offered to all patients suffering post-COVID-19 symptoms, not only those with laboratory confirmation and considered independently from acute illness severity. This tool offers a structure for a remote assessment. Post-COVID-19 programmes should include SOB, fatigue and mood disturbance management.

Defence Medical Rehabilitation Centre (DMRC) COVID-19 Recovery Service.

Coronavirus disease 2019 (COVID-19) causes significant mortality and morbidity, with an unknown impact in the medium to long term. Evidence from previous coronavirus epidemics indicates that there is likely to be a substantial burden of disease, potentially even in those with a mild acute illness. The clinical and occupational effects of COVID-19 are likely to impact on the operational effectiveness of the Armed Forces. Collaboration between Defence Primary Healthcare, Defence Secondary Healthcare, Defence Rehabilitation and Defence Occupational Medicine resulted in the Defence Medical Rehabilitation Centre COVID-19 Recovery Service (DCRS). This integrated clinical and occupational pathway uses cardiopulmonary assessment as a cornerstone to identify, diagnose and manage post-COVID-19 pathology.

Effectiveness of eHealth therapeutic education interventions in the management of fibromyalgia: protocol for a systematic review and meta-analysis.

INTRODUCTION: Non-pharmacological approaches have shown promising results in improving symptoms and quality of life of patients with fibromyalgia. However, these approaches may not be easily accessible or feasible for everyone. eHealth interventions may offer a more convenient and cost-effective approach to reach a wider range of patients with fibromyalgia and improve their outcomes. As eHealth tools become more prevalent in clinical practice, it is crucial to understand their effectiveness, limitations and how they can be integrated into standard care to optimise clinical outcomes. This systematic review aims to evaluate the effectiveness of eHealth therapeutic education interventions in managing fibromyalgia. METHODS AND ANALYSIS: Randomised controlled trials including eHealth therapeutic education interventions for individuals ≥18 years old with fibromyalgia, published in English or Spanish, will be retrieved by searching the databases PubMed, CINAHL Plus, EMBASE, Scopus, ISI Web of Science, PsycINFO and the Cochrane Central Register of Controlled Trials. Covidence software will be used for the selection of studies and data extraction. The risk of bias and the certainty of evidence will be assessed using the Cochrane Risk of Bias Assessment tool. We plan to perform a meta-analysis contingent on the number of studies retrieved and the interstudy heterogeneity, which will be explored with I2 statistics. ETHICS AND DISSEMINATION: This protocol and the subsequent systematic review will not collect individual-level data and do not require approval by an ethical committee. We intend to disseminate the study results via peer-reviewed scientific journals and relevant (inter)national conferences. PROSPERO REGISTRATION NUMBER: CRD42022343373.

Use of symptom-guided physical activity and exercise rehabilitation for COVID-19 and other postviral conditions.

There are many similarities in symptoms between postviral conditions, including clinical features such as fatigue, reduced daily activity and postexertional symptom exacerbation. Unfavourable responses to exercise have influenced the wider debate on how to reintegrate physical activity (PA) and exercise while simultaneously managing symptoms during recovery from post-COVID-19 syndrome (or Long COVID). This has resulted in inconsistent advice from the scientific and clinical rehabilitation community on how and when to resume PA and exercise following COVID-19 illness. This article provides commentary on the following topics: (1) controversies surrounding graded exercise therapy as a treatment modality for post-COVID-19 rehabilitation; (2) evidence supporting PA promotion, resistance exercise and cardiorespiratory fitness for population health, and the consequences of physical inactivity in patients with complex rehabilitation needs; (3) population-based challenges for UK Defence Rehabilitation practitioners for the management of postviral conditions; and (4) 'symptom guided PA and exercise rehabilitation' as an appropriate treatment option for managing individuals with multifaceted medical needs.

Physical performance testing in post-COVID-19 patients: protocol for a systematic review of psychometric measurement properties.

INTRODUCTION: COVID-19 is an infectious disease that causes severe acute respiratory syndrome. A large variety of exercise capacity tests are used for the evaluation of post-COVID-19 patients, but the psychometric properties of these exercise tests remain undetermined in this population. This study aims to critically appraise, compare and summarise the psychometric properties (validity, reliability and responsiveness) of all physical performance tests that are used to assess exercise capacity in post-COVID-19 patients. METHODS AND ANALYSIS: This systematic review protocol follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols guidelines. We will include studies with hospitalised adult post-COVID-19 patients (aged 18 years or older and with a confirmed diagnosis of COVID-19). The research will cover randomised controlled trials (RCTs), quasi-RCTs and observational studies published in English and performed in the following settings: hospital, rehabilitation centre, outpatient clinic. We will search the following databases with no date restrictions: PubMed/MEDLINE, EMBASE, SciELO, Cochrane Library, CINAHL and Web of Science. Two authors will independently assess the risk of bias (using the Consensus-Based Standards for the Selection of Health Measurement Instruments Risk of bias checklist) and the certainty of evidence (using the Grading of Recommendations, Assessment, Development and Evaluations). According to the results obtained, data will be meta-analysed or reported narratively. ETHICS AND DISSEMINATION: No ethical approval is required for this publication since it will be based on published data. Results of this review will be disseminated via peer-reviewed publications and conference presentations. PROSPERO REGISTRATION NUMBER: CRD42021242334.

Developing a Long-COVID follow-up protocol in a Portuguese tertiary hospital

About a third of COVID-19 patients experience ongoing symptoms that have been referred to as long-COVID. In cooperation with Rehabilitation Medicine and Psychology departments, we developed a protocol for evaluation and further referral of the long-COVID patients that sought our Emerging Infectious Diseases (EID) consultation. The aim was to characterize the symptoms according to their frequency and to develop a screening tool that allows referral to intervention programs. Long-COVID was defined as persistent or new-onset symptoms 12 or more weeks after initial infection. In our EID consultation all patients answered a questionnaire regarding the evolution and impact on daily activities of the persistent symptoms, using a 6-point Likert scale. Participants (n=42) had a mean age of 44.8 years (IQR 18.8) and 76% were female. Ninety-five percent of the patients had a mild to moderate course of acute infection. Fatigue (78.6%), physical capacity impairment (74%), brain fog (62%), anxiety and sleep disorders (52% each) were the most frequently reported symptoms. Regarding the impact of persistent symptoms, 50% of the patients with anxiety disorders, 69% of the ones reporting brain fog and 71% of those with physical capacity impairment reported being moderately or more affected on their daily activities by that symptom. When asked "Did you recover your previous health status?" all patients answered no. As the number of new infections continues to rise worldwide, long-COVID will be a challenging burden to healthcare systems and societies. Establishing a follow-up protocol and a reliable screening tool will allow us to reach a wider population and also promote a better and patient-centered use of medical resources.

Physical and cognitive impairments in people suffering from long COVID: protocol for a longitudinal population-based cohort study.

INTRODUCTION: Approximately 33% of people who contracted COVID-19 still experience symptoms 12 weeks after infection onset. This persistence of symptoms is now considered a syndrome itself called 'long COVID'. Evidence regarding long COVID and its cognitive and physical impacts is growing, but the literature is currently lacking objectively measured data to guide towards adapted healthcare trajectories. The objectives are to describe the physical and cognitive impairments experienced by individuals living with long COVID using self-reported and clinical objective measures, and to compare the evolution over time of the physical and cognitive state between adults living with long COVID (at least one physical or cognitive COVID-19 symptom for more than 12 weeks following infection; long COVID group), people who developed COVID-19 but did not experience persistent symptoms (short COVID group) and people who did not develop COVID-19 (control group). METHODS AND ANALYSIS: In this longitudinal cohort study, 120 participants will be recruited in each group. Variables will be collected through three evaluation sessions over 6 months (baseline, 3 months, 6 months). Variables include self-administered questionnaires on health-related quality of life, comorbidity, sleep, pain, anxiety, depressive symptoms, fatigue and cognitive function, as well as objective measures of cognitive (attention, memory, executive functioning) and physical (grip strength, balance, gait speed, gait endurance, VO2, frailty) functions. Activity, heart rate and sleep will be monitored with a fitness tracker watch for 7 days following evaluation sessions. Maximum-likelihood analyses of variance (ANOVAs) will be used to compare data at baseline between groups. Repeated measures ANOVAs will be used to compare the longitudinal performance variations across groups of the self-reported and clinical variables. ETHICS AND DISSEMINATION: Ethics committees of the CIUSSS de la Capitale-Nationale and CIUSSS de l'Est-de-l'Île-de-Montréal approved the project. Results will be disseminated through clinical and community platforms as well as through peer-reviewed manuscripts and international conferences. TRIAL REGISTRATION NUMBER: NCT05216536.

Adherence to physical rehabilitation delivered via tele-rehabilitation for people with multiple sclerosis: a scoping review protocol.

INTRODUCTION: Using tele-rehabilitation methods to deliver exercise, physical activity (PA) and behaviour change interventions for people with multiple sclerosis (pwMS) has increased in recent years, especially since the SARS-CoV-2 pandemic. This scoping review aims to provide an overview of the literature regarding adherence to therapeutic exercise and PA delivered via tele-rehabilitation for pwMS. METHODS AND ANALYSIS: Frameworks described by Arksey and O'Malley and Levac et al underpin the methods. The following databases will be searched from 1998 to the present: Medline (Ovid), Embase (Ovid), CINAHL (EBSCOhost), Health Management Information Consortium Database, ProQuest Dissertations and Theses Global, Pedro, Cochrane Central Register of Controlled Trials, US National Library of Medicine Registry of Clinical Trials, WHO International Clinical Trials Registry Platform portal and The Cochrane Database of Systematic Reviews. To identify papers not included in databases, relevant websites will be searched. Searches are planned for 2023. With the exception of study protocols, papers on any study design will be included. Papers reporting information regarding adherence in the context of prescribed therapeutic exercise and PA delivered via tele-rehabilitation for pwMS will be included. Information relating to adherence may comprise; methods of reporting adherence, adherence levels (eg, exercise diaries, pedometers), investigation of pwMS' and therapists' experiences of adherence or a discussion of adherence. Eligibility criteria and a custom data extraction form will be piloted on a sample of papers. Quality assessment of included studies will use Critical Appraisal Skills Programme checklists. Data analysis will involve categorisation, enabling findings relating to study characteristics and research questions to be presented in narrative and tabular format. ETHICS AND DISSEMINATION: Ethical approval was not required for this protocol. Findings will be submitted to a peer-reviewed journal and presented at conferences. Consultation with pwMS and clinicians will help to identify other dissemination methods.

Effects of home healthcare for adults with chronic respiratory diseases and post-COVID-19 syndrome on hospital bed turnover rate: a protocol of systematic review with meta-analysis.

INTRODUCTION: Chronic respiratory diseases (CRDs) have a high prevalence, morbidity and mortality worldwide. After the COVID-19 pandemic, the number of patients readmitted after hospital discharge increased. For some populations, early hospital discharge and home healthcare may reduce health costs in patients treated at home when compared with those hospitalised. This study aims to systematically review the effectiveness of home healthcare for patients with CRDs and post-COVID-19 syndrome. METHODS AND ANALYSIS: We will search on MEDLINE, CENTRAL, Embase and PsycINFO. We will include randomised controlled trials (RCTs) and non-RCT studies reported in full text and abstracts. No language restriction will be applied. We will include studies related to adults with a diagnosis of CRDs or post-COVID-19 syndrome that compared in-patient hospital care with any home healthcare. We will exclude studies with participants with neurological, mental diseases, cancer or pregnant women. Two review authors will screen abstracts and select the eligible studies. To investigate the risk of bias, we will use the Cochrane 'Risk of Bias' tool for RCT, and the Risk of Bias In Non-randomised Studies-of Interventions for non-RCT. We will use the five Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) considerations to assess the quality of the evidence. Patients and the public will be involved in the preparation, execution and implementation phases of the review. ETHICS AND DISSEMINATION: No ethical approval is required because only published data will be analysed. The publication of the results in peer-reviewed journals and at relevant conferences will guide the direction of future research in the field and healthcare practice. The results will also be disseminated in plain language on social media to disseminate the knowledge to society and the public interested in the topic.

Frail2Fit study protocol: a feasibility and acceptability study of a virtual multimodal intervention delivered by volunteers to improve functional outcomes in older adults with frailty after discharge from hospital.

INTRODUCTION: Physical activity (PA) and replete nutritional status are key to maintaining independence and improving frailty status among frail older adults. In response to the COVID-19 pandemic, healthcare has increasingly turned to virtual modes of delivery and there is interest in the use of trained volunteers to deliver PA and nutrition interventions. We aim to evaluate the feasibility and acceptability of training hospital volunteers to deliver an online intervention, comprising exercise, behaviour change and nutrition support, to older people with frailty after discharge from hospital. METHODS: We will use a quasi-experimental mixed methods approach. Hospital volunteers (n=6) will be trained to deliver an online, 3-month, multimodal intervention to frail (Clinical Frailty Scale ≥5) adults ≥65 years (n=30) after discharge from hospital. Feasibility will be assessed by determining the number of volunteers recruited, trained and retained at the end of the study; the proportion of intervention sessions delivered; participant recruitment, retention and adherence to the intervention. To determine the acceptability of the intervention, interviews will be conducted among a purposive sample of older adults, and volunteers. Secondary outcomes will include physical function, appetite, well-being, quality of life, anxiety and depression, self-efficacy for managing chronic disease and PA. Outcomes will be measured at baseline, 3 months and 6 months. ANALYSIS: Descriptive statistics will be used to describe feasibility and adherence to the intervention. Secondary outcomes at baseline will be compared at 3 and 6 months. Interviews will be transcribed verbatim and analysed using thematic analysis. ETHICS AND DISSEMINATION: Health Research Authority ethical approval was obtained on 30 May 2022 (reference: 22/WA/0155). Results will be disseminated through peer-reviewed journal articles, volunteer organisations, National Health Service communication systems and social media platforms. A toolkit will be developed to facilitate roll out of volunteer training. TRIAL REGISTRATION NUMBER: NCT05384730.

Reduced athletic performance post-COVID-19 is associated with reduced anaerobic threshold.

Detailed characterisation of cardiopulmonary limitations in patients post-COVID-19 is currently limited, particularly in elite athletes. A male elite distance runner in his late 30s experienced chest pain following confirmed COVID-19. He underwent cardiopulmonary exercise testing (CPET) at 5 months postacute illness. Subjective exercise tolerance was reduced compared with normal, he described inability to 'kick' (rapidly accelerate). His CPET was compared with an identical protocol 15 months prior to COVID-19. While supranormal maximal oxygen uptake was maintained (155% of peak predicted V̇O2) anaerobic threshold (AT), a better predictor of endurance performance, reduced from 84% to 71% predicted peak V̇O2 maximum. Likewise, fat oxidation at AT reduced by 21%, from 0.35 to 0.28 g/min. Focusing exclusively on V̇O2 maximum risks missing an impairment of oxidative metabolism. Reduced AT suggests a peripheral disorder of aerobic metabolism. This finding may result from virally mediated mitochondrial dysfunction beyond normal 'deconditioning', associated with impaired fat oxidation.

Piloting an online telecoaching community-based exercise intervention with adults living with HIV: protocol for a mixed-methods implementation science study.

INTRODUCTION: Our aim is to evaluate the implementation of an online telecoaching community-based exercise (CBE) intervention with the goal of reducing disability and enhancing physical activity and health among adults living with HIV. METHODS AND ANALYSIS: We will conduct a prospective longitudinal mixed-methods two-phased intervention study to pilot the implementation of an online CBE intervention with ~30 adults (≥18 years) living with HIV who consider themselves safe to participate in exercise. In the intervention phase (0-6 months), participants will take part in an online CBE intervention involving thrice weekly exercise (aerobic, resistance, balance and flexibility), with supervised biweekly personal training sessions with a fitness instructor, YMCA membership providing access to online exercise classes, wireless physical activity monitor to track physical activity and monthly online educational sessions on topics related to HIV, physical activity and health. In the follow-up phase (6-12 months), participants will be encouraged to continue independent exercise thrice weekly. Quantitative assessment: Bimonthly, we will assess cardiopulmonary fitness, strength, weight, body composition and flexibility, followed by administering self-reported questionnaires to assess disability, contextual factor outcomes (mastery, engagement in care, stigma, social support), implementation factors (cost, feasibility, technology), health status and self-reported physical activity. We will conduct a segmented regression analyses to describe the change in level and trend between the intervention and follow-up phases. Qualitative assessment: We will conduct online interviews with a subsample of ~10 participants and 5 CBE stakeholders at baseline (month 0), postintervention (month 6) and end of follow-up (month 12) to explore experiences, impact and implementation factors for online CBE. Interviews will be audiorecorded and analysed using content analytical techniques. ETHICS AND DISSEMINATION: Protocol approved by the University of Toronto Research Ethics Board (Protocol # 40410). Knowledge translation will occur in the form of presentations and publications in open-access peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT05006391.

The headache of diagnosing cerebellitis

Case Report:We describe a case of a non-verbal 5-yearold patient with autism and global developmental delay who presented with headache, nausea, vomiting, and decreased oral intake and found to have acute cerebellar syndrome/cerebellitis secondary to COVID-19 infection. Method(s): Chart Review. Summary of Results: A 5-year-old male with autism spectrum disorder and global developmental delay presented with one week history of headache, nausea, and non-bilious, non-bloody emesis. Despite intravenous fluid resuscitation and anti-emetic treatment, the patient continued to have persistent emesis with decreased oral intake and urine output. Physical exam findings were notable for aniscoria with right pupil larger than left, fixed upward gaze deviation, horizontal nystagmus, and nuchal rigidity. Patient was able to move all extremities spontaneously with normal tone and without rigidity or hyperreflexia. A complete blood cell count was consistent with the following: WBC 17.29 K/uL, hemoglobin level 12.8 g/dL, hematocrit 38.9%, and platelet count 482 K/ uL. C-reactive protein <4.0 mg/L and procalcitonin 0.12 ng/mL. CT Head on hospital day one showed no acute intracranial abnormality. Due to the patient's acute neurological changes, MRI brain was obtained and revealed patchy areas of hyperintensity in both the cerebellar hemispheres with moderate swelling of the cerebellum causing narrowing of the posterior fossa extra-axial cerebrospinal fluid (CSF) spaces. In addition, there was obstruction of the cerebral aqueduct due to extrinsic mass effect by the swollen cerebellum. CSF studies were notable for the following: 148 total nucleated cells with 75% lymphocytes and 17% monocytes and 2 red blood cells, protein was elevated at 113 mg/dL, and glucose was normal at 52 mg/dL. Meningitis and encephalitis panel was without any acute findings. Other laboratory testing was negative for tuberculosis, syphilis, chlamydia, HIV, and EBV. The patient tested positive for COVID-19 virus about one month prior to the onset of symptoms. Imaging and laboratory results in the setting of obstructive hydrocephalus with associated symptoms of nausea, emesis, headache, and upward gaze deviation are consistent with acute cerebellar syndrome, or cerebellitis. Due to obstructive hydrocephalus and inflammation of the cerebellum, patient was started on high-dose steroids, and neurosurgery placed external ventricular drain (EVD). The patient worked closely with physical medicine and rehabilitation as well as speech therapy, physical therapy, and occupational therapy to make a full recovery following this illness. Conclusion(s): Headache, nausea, and vomiting are often seen as benign findings;however, it is important to obtain specific details regarding the timing of symptoms, especially in the setting of a non-verbal patient. Because inflammation of the cerebellum can lead to hydrocephalus and potential herniation, prompt diagnosis is crucial to prevent long term effects of cerebellitis.

Changing characteristics of post-COVID-19 syndrome: Cross-sectional findings from 458 consultations using the Stanford Hall remote rehabilitation assessment tool.

BACKGROUND: In the UK, there have been multiple waves of COVID-19, with a five-tier alert system created to describe the transmission rate and appropriate restrictions. While acute mortality decreased, there continued to be a significant morbidity, with individuals suffering from persistent, life-restricting symptoms for months to years afterwards. A remote rehabilitation tool was created at the Defence Medical Rehabilitation Centre (DMRC) Stanford Hall to assess post-COVID-19 symptoms and their impact on the UK military.This study aims to understand changes in post-COVID-19 syndrome between wave 1 and wave 2, identify interactions between alert level and symptoms and investigate any predictive nature of acute symptoms for postacute symptomology in a young, physically active population. METHODS: Cross-sectional study of 458 consecutive remote rehabilitation assessments performed at DMRC Stanford Hall between 2 April 2020 and 29 July 2021. Consultations were coded, anonymised, and statistical analysis was performed to determine associations between acute and postacute symptoms, and between symptoms, alert levels and waves. RESULTS: 435 assessments were eligible; 174 in wave 1 and 261 in wave 2. Post-COVID-19 syndrome prevalence reduced from 43% to 2% between the waves. Acutely, widespread pain was more prevalent in wave 2 (p<0.001). Postacutely, there was increased anxiety (p=0.10) in wave 1 and increased sleep disturbance (p<0.001), memory/concentration issues (p<0.001) and shortness of breath/cough (p=0.017) in wave 2. Increasing alert level was associated with increased postacute symptom prevalence (p=0.046), with sleep disturbance increasing at higher alert level (p=0.016). Acute symptoms, including fatigue, sleep disturbance and myalgia, were associated with multiple postacute symptoms. CONCLUSIONS: This study reports the overall prevalence and symptom burden in the UK military in the first two waves of COVID-19. By reporting differences in COVID-19 in different waves and alert level, this study highlights the importance of careful assessment and contextual understanding of acute and postacute illnesses for individual management plans.

Effects of a 12-week, seated, virtual, home-based tele-exercise programme compared with a prerecorded video-based exercise programme in people with chronic neurological impairments: protocol for a randomised controlled trial.

INTRODUCTION: Exercise is vital to staying well and preventing secondary complications in people with chronic neurological impairments (CNI). Appropriate exercise is often inaccessible to this population. The purpose of the study is to investigate the effects of a seated, virtual exercise programme on heart rate, recovery, fatigue, pain, motivation, enjoyment and quality of life in people with CNI. METHODS AND ANALYSIS: Individuals with CNI will be screened for eligibility, and 60 participants will be randomised 1:1 into either a live or prerecorded group. There is no geographical limitation to where participants reside, since participation is virtual. The study will be coordinated by one site in White Plains, New York, USA. The live group will exercise with an instructor via Zoom while the prerecorded group will exercise at their chosen time using prerecorded videos, 3×/week for 12 weeks. PRIMARY OUTCOME MEASURES: change in heart rate during exercise/recovery. SECONDARY OUTCOME MEASURES: fatigue, motivation, level of pain and exertion, physical well-being, enjoyment of physical activity, motivation and quality of life. Outcomes will be assessed at baseline, midpoint, end of study and 1-month poststudy. Adverse events, medication changes and physical activity will be tracked throughout. Within-group and between-group comparisons will be performed by using analysis of covariance and regression. ETHICS AND DISSEMINATION: BRANY IRB approval: 22 September 2020, protocol #20-08-388-512. All participants will provide written informed consent. Results will be disseminated through presentations, publications and ClinicalTrials.gov. TRIAL REGISTRATION NUMBER: NCT04564495.

Relationship between Tai Chi and clinical outcomes in elderly patients with COVID-19: a protocol for systematic review and dose-response meta-analysis.

INTRODUCTION: COVID-19 has posed a serious threat to people worldwide, especially the older adults, since its discovery. Tai Chi as a traditional Chinese exercisethat belongs to traditional Chinese medicine has proven its effectiveness against COVID-19. However, no high-quality evidence is found on the dose-response relationships between Tai Chi and clinical outcomes in patients with COVID-19. This study will evaluate and determine the clinical evidence of Tai Chi as a treatment in elderly patients with COVID-19. METHODS AND ANALYSIS: The following electronic bibliographical databases including PubMed, EMBASE, Web of Science, Cochrane Library, China National Knowledge Infrastructure, VIP Database and Wanfang Database will be screened from their inception date to 30 June 2022. All eligible randomised controlled trials or controlled clinical trials related to Tai Chi for elderly patients with COVID-19 will be included. The primary outcomes are forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC) and FEV1/FVC ratio (FEV1%). The secondary outcomes are the time of main symptoms disappearance, length of hospital stay, serum levels of interleukin (IL)-6, IL-1b and tumour necrosis factor-α, and adverse event rate. Two independent reviewers will select the studies, extract the data, and analyse them on EndNote V.X9.0 and Stata V.12.1. The robust error meta-regression model will be used to establish the dose-response relationships between Tai Chi and clinical outcomes. The heterogeneity and variability will be analysed by I2 and τ2 statistics. Risk of bias, subgroup analysis and sensitivity analysis will also be performed. The quality of evidence will be assessed by the Grading of Recommendations Assessment, Development and Evaluation, and the risk of bias will be evaluated by using the Physiotherapy Evidence Database Scale. ETHICS AND DISSEMINATION: This study will review published data; thus, obtaining ethical approval and consent is unnecessary. The results will be disseminated through peer-reviewed publications.

Recruitment in the Digital Age: The Implications of Social Media for Physical Medicine and Rehabiliation Applicants

Objective: To investigate the influence of social media interactions with medical students applying to Physical Medicine and Rehabilitation residency programs. Design(s): A cross-sectional online survey of Physical Medicine and Rehabilitation applicants recruited to a single university applicant pool that was generally representative of the nationwide applicant pool. Setting(s): Anonymous, voluntary, electronic questionnaire. Participant(s): United States medical students (31.2% female 67.5% male 1.3% prefer not to disclose) who applied to a Physical Medicine and Rehabilitation residency program. Intervention(s): None. Main Outcome Measure(s): Participant-reported measures by an electronic questionnaire. Result(s): Of the 77 applicants that responded to the survey, 53 (68.8%) followed residency program accounts on social media platforms. Of the social media platforms, Instagram was the most used at 86.8%, followed by Twitter at 56.6%. 86.8% of social media users (SMUs) interacted with residencies on social media platforms (e.g., commenting, liking, direct messaging), which 67.9% reported very positively or positively impacted their perception of residency programs. Overall, 81.1% of SMUs felt more connected to programs that they followed on social media platforms. Around half of SMUs rated that interactions were extremely helpful or very helpful in understanding local culture as well as residency program culture. In fact, 75.5% SMUs agreed that social media is either very important or important in the era of remote/zoom interviews. Interestingly, only a minority of SMUs (24.5%) agreed that interaction with residency programs on social media platforms was extremely or very influential in their ERAS rankings. Conclusion(s): As virtual interviews in Physical Medicine and Rehabilitation residency programs continue in the COVID era, this research indicates that social media plays a large role in program-to-applicant relations during recruitment season and should prompt more programs to foster a stronger connection with applicants through social media.

Cardiopulmonary exercise testing excludes significant disease in patients recovering from COVID-19.

OBJECTIVE: Post-COVID-19 syndrome presents a health and economic challenge affecting ~10% of patients recovering from COVID-19. Accurate assessment of patients with post-COVID-19 syndrome is complicated by health anxiety and coincident symptomatic autonomic dysfunction. We sought to determine whether either symptoms or objective cardiopulmonary exercise testing could predict clinically significant findings. METHODS: 113 consecutive military patients were assessed in a comprehensive clinical pathway. This included symptom reporting, history, examination, spirometry, echocardiography and cardiopulmonary exercise testing (CPET) in all, with chest CT, dual-energy CT pulmonary angiography and cardiac MRI where indicated. Symptoms, CPET findings and presence/absence of significant pathology were reviewed. Data were analysed to identify diagnostic strategies that may be used to exclude significant disease. RESULTS: 7/113 (6%) patients had clinically significant disease adjudicated by cardiothoracic multidisciplinary team (MDT). These patients had reduced fitness (V̇O2 26.7 (±5.1) vs 34.6 (±7.0) mL/kg/min; p=0.002) and functional capacity (peak power 200 (±36) vs 247 (±55) W; p=0.026) compared with those without significant disease. Simple CPET criteria (oxygen uptake (V̇O2) >100% predicted and minute ventilation (VE)/carbon dioxide elimination (V̇CO2) slope <30.0 or VE/V̇CO2 slope <35.0 in isolation) excluded significant disease with sensitivity and specificity of 86% and 83%, respectively (area under the receiver operating characteristic curve (AUC) 0.89). The addition of capillary blood gases to estimate alveolar-arterial gradient improved diagnostic performance to 100% sensitivity and 78% specificity (AUC 0.92). Symptoms and spirometry did not discriminate significant disease. CONCLUSIONS: In a population recovering from SARS-CoV-2, there is reassuringly little organ pathology. CPET and functional capacity testing, but not reported symptoms, permit the exclusion of clinically significant disease.
