Clinical Study Designed to Evaluate the Effect of CimetrA in Patients Diagnosed With COVID-19

A preparation of CimertrA, comprising Artemisinin, Curcumin, and Boswellia, and Vitamin C in a nanoparticular formulation, is proposed as a treatment for the disease associated with the novel coronavirus SARS-CoV-2. This initiative is presented under the urgent circumstances of the fulminant pandemic caused by this lethal disease, which is known as COVID-19 and has spread across the globe causing death and disrupting the normal function of modern society. The grounds for the proposal are rooted in existing knowledge on the components and pharmacological features of this formulation and their relevance to the current understanding of the disease process being addressed. The severe acute respiratory syndrome-associated coronavirus disease 2019 (COVID-19) illness results from the immediate response to the viral infection as well as from a subsequent host inflammatory response. Systemic proinflammatory cytokines and biomarkers are elevated as the disease progresses towards its advanced stages, and correlate with worse chances of survival. Serum cytokine levels that are elevated in patients with Covid-19-associated cytokine storm include interleukin-1?, interleukin-6, IP-10, TNF, interferon-?, macrophage inflammatory protein (MIP) 1? and 1?, and VEGF. Higher interleukin-6 levels are strongly associated with shorter survival. The relative frequencies of circulating activated CD4+ and CD8+ T cells and plasmablasts are increased in Covid-19. In addition to the elevated systemic cytokine levels and activated immune cells, several clinical and laboratory abnormalities, such as elevated CRP and d-dimer levels, hypoalbuminemia, renal dysfunction, and effusions, are also observed in Covid-19. Laboratory test results reflecting hyper inflammation and tissue damage were found to predict worsening outcomes in Covid-19. CimetrA, comprising Artemisinin, Curcumin, Boswellia, and Vitamin C in a nanoparticular formulation, has been studied on patients with COVID-19 in a randomized double-blind control Phase II study (MGC-006 - under a previous product name - ArtemiC). The study product demonstrated excellent safety and efficacy profiles. Experiments performed in vitro with CimetrA demonstrated the ability to reduce cytokine elevation in response to stimulation of human PBMC preparations. The currently proposed Multi-center multinational-controlled study is designed to include 252 adult patients who suffer from moderate COVID-19 infection. Safety will be assessed through collection and analysis of adverse events, blood and urine laboratory assessments, and vital signs. After the screening visit, the study drug will be administrated twice a day morning and evening (every 12 hours) during (day 1 and day 2) The patients will be randomized in 1:1:1 ratio to study drug (CimetrA) in addition to Standard of Care (Arm 1 (CimetrA-1) or Arm 2 (CimetrA-2)) or Placebo in addition to Standard of Care (Arm 3).

Impact of Perceived Control on Operational Strain: a Study of COVID-19 Pandemic Caregivers and Military Personnel on Operational Missions

Stress is underpinned by a biological reaction of the organism allowing the production of energy to respond to a change in the environment (or stressor). Stress reaction is expressed in behavioural, cognitive, emotional and physiological terms. This biological response is non-specific because it is the same regardless of the stressor. Its evolution over time has been conceptualised by Hans Selye (1956) in the General Adaptation Syndrome (GAS) which comprises three successive phases. (i) The first phase, known as the alarm phase, corresponds to the activation of all biological mechanisms according to a trend regulation, allowing a rapid response to the stressor. (ii) The second phase of resistance which adjusts the stress response to the intensity of the perceived aggression according to a constant regulation. (iii) When the aggression disappears, a recovery phase dominated by the return of the parasympathetic brake allows a return to homeostasis (eustress). The "primum movens" of all pathologies is therefore the inability of the individual to adapt his stress response in duration and/or intensity to the course of the phases of the GAS (distress). The perception of not being in control of the situation contributes to the perceived stress and constitutes a well-established risk of distress. It is a risk factor for the emergence of burnout. It induces a biological cost called allostatic cost. Allostasis is a concept that characterizes the process of restoring homeostasis in the presence of a physiological challenge. The term "allostasis" means "achieving stability through change", and refers in part to the process of increasing sympathetic activity and corticotropic axis to promote adaptation and restore homeostasis. Allostasis works well when allostasis systems are initiated when needed and turned off when they are no longer required. Restoring homeostasis involves effective functioning of the parasympathetic system. However, when the allostasis systems remain active, such as during chronic stress, they can cause tissue burnout and accelerate pathophysiological processes. The perception of uncontrollability depends on the stress situation, the psychological and physiological characteristics of the subject and his or her technical skills in responding to the stressors of the situation. In particular, subjects with a high level of mindfulness are more accepting of uncontrollability and less likely to activate the stress response. The COVID-19 pandemic situation is a situation characterized by many uncertainties about the individual, family and work environment and the risk of COVID infection. Healthcare workers, like the military, are high-risk occupations that are particularly exposed to these uncertainties in the course of their work and continue to work in an uncertain situation. These professionals are described as a population at risk of occupational/operational burnout that the level of burnout operationalises. This ancillary study in a population of civilian and military non-healthcare workers will complement the study conducted among military health care workers. It will make it possible to isolate the specificity of each profession (civilian or military, healthcare personnel or not) with regard to the risk of burnout in the COVID context. The objective of this project is to evaluate the impact of the perception of non-control in the operational burnout of experts in their field of practice and to study the psychological and physiological mechanisms mediating the relationship between the subject's characteristics, perceived non-control and burnout.

Recovery of Exertion Ability Following COVID-19 Infection in Military Staff

The Paris Fire Brigade staff have been particularly exposed to COVID-19 due to rescue and care activities for victims at risk in Paris area (where the virus was actively circulating). In addition, when the pandemic began in France, they had to take care of patients before procedures to protect caregivers were implemented. The contamination of young military personnel, whose physical capacity was put into strain at work, raises the question of the consequences of COVID-19 on their physical fitness. At the time, the medium- and long-term evolution of this disease and its possible repercussions on physical fitness are unknown. Moreover, like any soldiers who have been confined, they may present at least a cardio-respiratory deconditioning (sometimes independent of the disease making it difficult to distinguish between a sequelae of the infection or rehabilitation). Based on previous coronavirus epidemics (Sars-Cov 1 and Mers-Cov), it appears that long-term sequelae are possible even in mild forms and can result in an alteration of exertion ability. In the current context and in the absence of national or international recommendations on the return to physical activity, the French Armed Forces Health Service has proposed a simple management plan aiming at: i) allowing mass screening for possible exercise intolerance and targeting at-risk personnel, ii) allowing individualized re-training and iii) guaranteeing that military personnel can carry out their mission without jeopardizing their health.

Effectiveness of a Novel Respirator With Chitosan Nanoparticles

The use of nanomaterials in semi-facial respirators could decrease the permeability of particles and promote a biocidal effect compared to conventional respirators (N95) and, therefore, to enhance the filtering power, aiming to mitigate harmful effects of bacteria and viruses. Chitosan is a natural cationic polymer derived from chitin, with characteristics such as being biodegradable, biocompatible, non-toxic, and presenting antimicrobial activity. This polymer has virucidal activity in several types of viruses, including other coronaviruses, given the attractive factor of its cationic charge for negative charges. The effectiveness of a novel individual protection semi-facial respirator (called VESTA) will be investigated, compared to a conventional N95 respirator. The respirators will be tested in healthcare professionals working in hospital environments and the effectiveness will be attributed to the lower incidence rate of infection by the SARS-CoV-2, and to the ability to filter these viruses after use by healthcare professionals exposed to potentially contaminated environments. The study will be carried out in two stages: i) Randomized Controlled Trial with reduced sample to confirm the sample size calculation, and ii) Randomized Controlled Trial (RCT). The RCT will be conducted with healthcare professionals who have contact with environments/patients infected by SARS-CoV-2 in hospital sectors with greater vulnerability to infection (urgency, emergency and intensive care units). The RCT will be conducted initially with a group of sixty participants (n = 30 in each group) for initial investigation of the potential for efficacy with the use of the respirators (VESTA and conventional N95) in two sectors (emergency and ICU) in a reference Hospital for COVID-19. The RCT will consist of two parallel groups: (1) Experimental Group (GExp) that will use the novel respirator (VESTA) and (2) Control Group (CG) that will use the standard respirator (N95). Participants will be recruited from participating hospitals and will be accompanied by 21 days in approximately eight consecutive shifts (ranging from shifts lasting 6 to 12 hours each, followed by approximately 36 hours of rest). Participants will be assessed at baseline (T0), at the end of the 10th day (T1), and at the end of the 21st day (T2). The respirators will be assessed after the end of the 1st hospital shift for morphological characterization (virus quantity and inactivation).

Olfactory Training for Olfactory Dysfunction After Coronavirus Disease - 19 (COVID-19)

It is a randomized controlled clinical trial study that aims to follow a sample of individuals with persistent olfactory dysfunction post-COVID-19. The aim of this study is assess the clinical outcomes of olfactory training therapy in the treatment of persistent olfactory dysfunctions after COVID-19. The sample will consist of 350 participants, being 300 individuals with persistent olfactory dysfunction post-COVID-19 and 50 healthy individuals. Volunteers' will be separated in two experimental groups (1 and 2 ) and a control group. All participants will be submitted to clinical evaluation that include the Connecticut Chemosensory Clinical Research Test (CCCRT), an olfactory test to diagnose anosmia and hyposmia, and two skull Magnetic Resonance imaging (MRI). Only participants of Experimental group 1 will be submitted to an olfactory training with essences oils. Experimental group 2 will only receive a clinical follow-up after three months and control group will be only submitted to neurological exam, olfactory test, MRI imaging and test their ability to discriminate the essence oils used in olfactory training. As a result, is expected a better understanding of the characteristics of olfactory dysfunction caused by Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus infection, as well as the effectiveness and viability of using Olfactory Training as a therapeutic alternative.

Short and Medium-term Effects of Pulmonary Rehabilitation in Mild to Critical Post-acute COVID-19

As a direct consequence of the COVID-19 pandemic, it is assumed that the number of patients with COVID-19-related disabilities will increase significantly. Patients with mild, severe, and critical forms of the disease show long-term sequelae in different systems (respiratory, muscular, psychological, cognitive etc.). Persistent dyspnea is a frequently described symptom after the acute phase of the disease. Coupled with reduced oxygen saturation, an increased risk of developing lung fibrosis has been observed. Specialized rehabilitation medicine (e.g. pulmonary rehabilitation) might counteract these long-term consequences and therefore seems to be a promising approach to treat long-term COVID-19 consequences. Further, there is scarce evidence about COVID-19 specific rehabilitation contents. It was suggested to use treatment regimes in analogy to patients with idiopathic pulmonary fibrosis. There is evidence that pulmonary rehabilitation improves physical performance, quality of life and reduces anxiety and depression symptoms in patients with idiopathic pulmonary fibrosis and other chronic respiratory diseases. Since impairments related to idiopathic pulmonary fibrosis also play an important role in COVID-19, the aim of this study is to evaluate the short and medium-term effects of a standardized 3-week pulmonary rehabilitation program. The results will be analyzed within the two cohorts (mild/moderate and severe/critical COVID 19) as well as between the two cohorts for the primary outcome. Furthermore, the effects of pulmonary rehabilitation will be compared with a retrospective cohort of idiopathic pulmonary fibrosis.
