Little is currently known about the immediate and long-term effect of COVID-19 on lungventilation (delivery of air to the lungs) and lung perfusion (delivery of blood to thelungs). Some people who survive COVID-19 may have lung ventilation and/or perfusioninjury that persists following COVID-19 recovery. This lung injury may be related toinflammation in the lung, breathlessness, exercise limitation and reduced quality oflife. Therefore, towards the goal of understanding the effects of COVID-19 on lunghealth, the purpose of this study is to characterize and understand the clinicalrelevance of COVID-19 related lung ventilation and perfusion injury and associatedinflammatory status, ≤4 weeks and 6-months following COVID-19 recovery in an asthmaticand healthy population. To do this, an asthmatic and healthy population who have, andhave not, been previously diagnosed with COVID-19 will be studied.

Viral pandemics, such as HIV and SARS-Cov-V1, have shown that they can lead to acute and/ or delayed neurological complications. At the actual context of the pandemicCoronavirus disease 2019 (COVID-19), neurological manifestations seem to be confirmedsince in 85% of COVID-19 patients, present neurological symptoms, including anosmia,ageusia, periorbital pain, dizziness, fatigue, even moderate headache, moderate memoryand/or behavioral disorders.However, these neurological manifestations are not well studied and their radiologicalfeatures are not well described. It is therefore important to assess these potentialneurological complications in COVID-19 patients. To the investigator knowledge, there isno previous study in the literature describing spectral brain changes in COVID +patients. Thus, the goal of this work is to describe the radiological semiology using MRIand particularly Magnetic Resonance Spectroscopic (MRS) biomarkers in the evaluation ofacute and / or delayed brain damage in COVID + patients presenting a neurologicalmanifestations that are initially related to the cranial nerves damage.

Currently, there is no approved treatment for COVID-19 in France, either for the acutephase, nor for the late chronic phase. the investigator suggest that nintedanib has thepotential to block the development of lung fibrosis when initiated early enough toinhibit the activation of mesenchymal cells and the progression of virus-inducedpulmonary fibrosis. Computerized Tomography (CT) manifestations of fibrosis or fibrousstripes are described in COVID-19 (Ye, Eur Radiol 2020). Pan et al observed fibrousstripes in 17% patients in the early phase of the disease (Pan, Eur Radiol 2020). Ye etal observed bronchiectasis in 2 patients (15.4%) and evidence of pulmonary fibrosis in 3patients (23.7%) at HRCT performed at 4 weeks (Ye, Eur Radiol 2020). Long term data arestill lacking in patients with COVID-19 and the investigators do not know how manypatients will have fibrotic sequelae from the acute illness.

Wider research context: Since the recognition of SARS-CoV-2 outbreak in 2019, there arenow over 126 million COVID-19 cases worldwide with more than 2.7 million deaths. Reportson neurological manifestations vary in prevalence rates (6-84%) and range from mild(headache, hyposmia, myalgia) to severe (encephalopathy, strokes, seizures). Little isknown about long-term neurological outcomes of COVID-19 patients. The investigatorspropose a structured protocol to capture persistent and delayed neurologicalmanifestations, neurocognitive deficits and quality of life (QoL) 3 and 12 months afterCOVID-19. Objectives: The investigators hypothesize that neurological manifestations andneuropsychological/cognitive deficits can be detected after COVID-19, substantiallyimpact on patients' QoL and can be correlated with structural neuroimaging findings. Mainobjectives are to assess firstly long-term prevalence rates and natural history ofneurological manifestations, secondly neuropsychological/cognitive deficits afterCOVID-19, thirdly the impact of COVID-19 on measures of mental health, QoL and functionaloutcome, fourthly to correlate neurological manifestations and distinct neurocognitivedeficits with structural MRI abnormalities, and Fifthly to compare these results to age-and sex matched controls hospitalized with pneumonia (Cpneum) and to healthy controls forMRI-data (Chealthy). Approach: The investigators aim to enrol at least 225 patients withCOVID-19, in addition to 50 Cpneum and 80 Chealthy. COVID-19 patients will include (groupOóne) outpatients presenting to the hospital, (group two) in-patients not requiring ICUadmission, and (group three) patients admitted to the ICU. The investigators will notinclude asymptomatic patients, patients not presenting to the hospital, and those who donot consent to participate. The standardized protocol includes a firstly a structuredneurological examination, secondly olfactory testing, thirdly assessment of QoL, mentalhealth and functional outcome at 3 and 12 months, and fourthly screening for cognitivedeficits (at 3 months) and a structured neuropsychological testing (at 12 months) inCOVID-19 patients and controls. In a subset of at least 120 COVID-19 patients and 50controls (Cpneum) high field MRI will be performed at 3 and 12 months. Innovation: Theinvestigators aim to quantify COVID-19 related and specific neurological manifestationsand their impact on the individual health condition. The novelty lies in the prospectivedesign, the longitudinal follow-up including and the inclusion of a control group whichallows us to explore the natural history of COVID-19 related neurological manifestations.Preliminary analysis of our ongoing 3-month follow-up suggests persistent neurologicalmanifestations and a significant impact of COVID-19 on mental health, cognition and QoL.The investigators believe that our study results likely influence the long-term care ofCOVID-19 patients and help to identify those, who need further neuro-rehabilitativesupport

Initially, it was suspected that Covid-19 would primarily affect the airways, but severalstudies have now shown that it is a disease with multisystem manifestations. Covid-19 hasthe potential to affect physical, cognitive, and psychological functions in multipleways. It has been clear that a significant proportion of patients with Covid-19 developlong-term symptoms. The term post-acute Covid-19 syndrome (PACS) is now used to describethe wide range of prolonged symptoms following the infection. Patients who have been inhospital for Covid-19 for a long time may need specialized rehabilitation, however, alsonon-hospitalized patients with mild symptoms may need specific rehabilitation to be ableto meet the complex symptoms and problems that may arise. Previous studies on therecovery and rehabilitation after other coronavirus shows the importance to developtailored interventions so that these patients receive appropriate rehabilitationThe aim of this study is to evaluate the effects of inspiratory muscle training on adultpatients with PACS and decreased respiratory muscle strength.A randomized controlled trial will be used. A total of 90 adult patients with PACS and 80% or less of predicted value in inspiratory muscle strength (maximal inspiratorypressure) will be eligible for enrollment. Patients will be randomized either to anintervention group or a control group. The intervention will consist of inspiratorymuscle training performed twice daily for 8 weeks. This will be combined with an 8-weekphysical exercise training program. The control group will perform the same physicalexercise training according to standard care. All measurements will be performed atbaseline and after 8 weeks.Primary outcome is maximal inspiratory pressure. Secondary outcomes are: Maximalexpiratory pressure, pulmonary function, physical capacity, physical activity,respiratory status and symptoms, health-related quality of life, work ability, fatigue,self-reported outcome measure of physical function and voice function.Covid-19 has the potential to affect physical, cognitive, and psychological functions inmultiple ways and lead to a negative impact on quality of life in the long-termperspective. Therefore, development of a rehabilitation program with specific tailoredinterventions will be necessary to improve physical and psychological function, as wellas health-related quality of life and work ability.

This study investigates the changes in practice by pulmonary procedural programs acrossthe United States as they faced the coronavirus pandemic. Information gathered from thisstudy may help guide pulmonary programs on a wider scale and improve their practice. Thestudy may also help researchers understand where they should focus research efforts tobetter respond to a pandemic in the future.

In March 2020, the World Health Organization (WHO) declared the novel coronavirus(COVID-19) a global pandemic. Ontario has confirmed more than 547,000 cases of COVID-19since testing began. For many of these patients, symptoms resolve within 4 weeks ofonset. However, it is becoming apparent that a significant number of individuals areexperiencing symptoms that persist long after the acute infection, known as Long COVID.These individuals have a wide constellation of presenting symptoms, often varying frominitial presentation. For this study, we will be enrolling individuals receiving care atThe Ottawa Hospital for Long COVID. This study aims to determine the following fourthings: 1) will adding electronic case management improve quality of life three monthsafter coming to hospital with Long COVID; 2) is the electronic case management platformcost effective; 3) is there any factors that predict outcomes at 3 months; 4) todetermine how a personalized rehabilitation program supported by a digital platform couldbe implemented for individuals with Long COVID. We will enroll individuals from TheOttawa Hospital who will then be randomly assigned to receive either usual care or usualcare plus electronic case management, through a platform called NexJ Connected Wellness.Participants will also complete questionnaires every 4 weeks for 3 months. We will belooking at quality of life, mental and physical health, cognitive symptoms, fatigue andpain.

The purpose of this study is to examine the effect of Andrographis Extract, BoesenbergiaExtract compared to standard treatment in asymptomatic COVID patients.

This is a phase Ⅰ/Ⅱ, single-center, randomized, double-blind, placebo-controlled study,to evaluate the safety, tolerability and immunogenicity of the recombinant COVID-19vaccine (Sf9 cells) in the subjects from healthy aged 6-17 years with immunizationprocedures 0, 21, 42 days and doses (10μg/20μg/40μg).

Background: Fatigue is among the most common symptoms of the long-term effects ofcoronavirus (long COVID). This study aims to compare the effectiveness of osteopathicmanipulative treatment (OMT) combined with physiotherapy treatment (PT) compared to PTalone on fatigue and functional limitations after two months post randomization in adultswith long COVID.Methods: This is a study protocol for a two-arm, assessor-blinded, pragmatic randomizedcontrolled superiority trial. Seventy-six participants will be randomly allocated toOMT+PT or PT. The PT includes usual care interventions including motor and respiratoryexercises targeting cardiorespiratory and skeletal muscle functions. The OMT entailsdirect, indirect, visceral, and cranial techniques. Patients will be evaluated before andafter a 2-month intervention program, and at 3-month follow-up session. Primaryobjectives comprise fatigue and functional limitations at 2-month post randomization asassessed by the fatigue severity scale and the Post-COVID Functional State scale.Secondary objectives comprise fatigue and functional limitations at 3 months, and theperceived change post-treatment as assessed by the Perceived Change Scale (PCS-patient).
