The purpose of this pilot study is to measure the impact of non-invasive pneumaticmanipulation of transthoracic pressure on oxygenation in patients with Acute RespiratoryDistress Syndrome (ARDS) due to Coronavirus Disease 2019 (COVID 19) who are on mechanicalventilator support. This will be achieved by a pneumatic Vest placed around the chestwall of consenting patients who meet inclusion criteria. The Vest is essentially anon-invasive segmental device placed upon the anterior and posterior right and leftaspects of the chest wall. The researchers have the ability to inflate and deflate thechambers of the Vest to achieve preset pressures as determined by the protocol andobserve the patient's physiological response. Participants will have up to four hours ofintervention with the study intervention, followed by 1 hour of post-interventionobservation.

The novel coronavirus (SARS-CoV-2) has spread all around the world and testing has poseda challenge globally. Health care providers are highly exposed and are an important groupto test. On top of these concerns, health care workers are also stressed by the needs onresponders in the COVID-19 crisis. The investigators will look at different ways tomeasure how common COVID-19 is among health care workers, how common is the presence ofantibodies by serological tests (also known as serostatus). The investigators willdescribe health worker mental and emotional well-being and their coping strategies intheir institutional settings. Lastly, the investigators will describe how knowingserostatus can affect individuals' mental and emotional well-being and how to cope in themidst of the COVID-19 response. This will help to how to better test and help healthcareworkers in the COVID-19 pandemic and prepare for possible future outbreaks.

This study is a Phase 1 / 2 trial to determine the safety and efficacy of CYNK-001, animmunotherapy containing Natural Killer (NK) cells derived from human placental CD34+cells and culture-expanded, in patients with moderate COVID-19 disease.

The COVID-19 pathology is frequently associated with diabetes mellitus and metabolicsyndrome. In the epidemic outbreak that exploded at the beginning of 2020 in the LombardyRegion, about two thirds of the patients who died from COVID-19 were affected by diabetesmellitus. COVID-19 occurs in 70% of cases with an inflammatory pathology of the airwaysthat can be fed by a cytokine storm and result in severe respiratory failure (10% cases)and death (5%). The pathophysiological molecular mechanisms are currently not clearlydefined. It is hypothesized that the transmembrane glycoprotein type II CD26, known forthe enzyme activity Dipeptilpeptidase 4 of the extracellular domain, may play a main rolein this condition. It is in fact considerably expressed at the level of parenchyma andpulmonary interstitium and carries out both systemic and paracrine enzymatic activity,modulating the function of various proinflammatory cytokines, growth factors andvasoactive peptides in the deep respiratory tract. Of particular interest is the factthat Dipeptilpeptidase 4 has been identified as a cellular receptor for S glycoprotein ofMERS-COV. In the case of the SARS-COV 2 virus, the main receptor is theAngiotensin-Converting Enzyme 2 protein, but a possible interaction withDipeptilpeptidase 4 also cannot be excluded. The selective blockade of Dipeptilpeptidase4 could therefore favorably modulate the pulmonary inflammatory response in the subjectaffected by COVID-19. This protein is also known for the enzymatic degradation functionof the native glucagon-like peptide 1, one of the main regulators of insulin secretion.This is why it is a molecular target in the treatment of diabetes (drugs that selectivelyinhibit Dipeptilpeptidase 4 are marketed with an indication for the treatment of type 2diabetes). It is believed that the use of a Dipeptilpeptidase 4 inhibitor in people withdiabetes and hospitalized for Covid-19 may be safe and of particular interest for anevaluation of the effects on laboratory and instrumental indicators of inflammatory lungdisease. Among the drugs that selectively block Dipeptilpeptidase 4, the one with thegreatest affinity is Sitagliptin.

The COVID-19 outbreak has been rapidly transmitted in late January 2020 and arousedenormous attention globally. The public at large may also experience boredom,disappointment, and irritability under the isolation measures. Depression and anxiety arecommon mental health problems experienced by university students. This survey aims toinvestigate the psychological impact of COVID 19 on students.

Patients with COVID-19 diagnoses are treated under isolation in hospitals and withhigh-stress level. Currently, there is little information on the mental healthimplications of exposure amongst COVID-19 survivors and their family members. Researchexploring the psychological impact amongst survivors of exposure to COVID-19 isdesperately needed to understand the effects, mental health toll, and support required insurvivors of COVID-19. This study aims to assess the psychological impact of the COVID-19outbreak on COVID-19 survivors and their family members.

The COVID-19 disease has been subject to numerous publications since its emergence.Almost 20% of people suffering from COVID-19 develop severe to critical symptoms andrequire hospitalization, often in Intensive Care Unit (ICU). Respiratory failure is themain reason for admission in ICU of these patients. Therapeutic strategies implementedfor the management of critically-ill patients may often lead to short-term muscular andfunctional alterations resulting in ICU-Acquired Weakness (ICUAW). These lead tolong-term disabilities expressing trough dependence and quality of life impairment ofsurvivors.The purpose of this study is to assess the quality of life, dependence and survival atone year in patients who survived from COVID-19 in ICU and are admitted in post-ICUsetting for difficult weaning purpose.Ancillary studies aim to assess the course of muscle function (atrophy, structuralmodifications), lung function (loss of aeration) and safety of early mobilization.

Experience from the 2003 Severe Acute Respiratory Syndrome (SARS) outbreak taught thathealthcare workers (HCWs) often experience chronic stress effects for months or yearsafter such an event, and that supporting HCWs requires attention to the marathon ofoccupational stress, not just the sprint of dramatic stressors that occur whileinfections are dominating the news. This study will test if the well-being of hospitalworkers facing a novel coronavirus outbreak is improved by adding either of twointerventions: (1) Peer Resilience Champions (PRC): an interdisciplinary team ofprofessionals who actively monitor for early signs of heightened stress within clinicalteams, liaise between staff and senior management to improve organizationalresponsiveness, and provide direct support and teaching (under the supervision of expertsin resilience, infection control, and professional education). Investigators will testthe effectiveness of this PRC Intervention by rolling it out to different parts of thehospital in stages and comparing levels of burnout before and after the interventionreaches particular teams and units (a stepped wedge design). By the end of the study, PRCSupport will have been provided to all clinical and research staff and many learners (>6,000 people). Note that the provision of PRC support will be directed to the entireorganization. The research portion of the study is the evaluation of PRC support througha repeated survey completed by consenting staff. Investigators will test theeffectiveness of the PRC by measuring trends in burnout and other effects of stress overthe course of the study in a subgroup of hospital workers (as many as consent, target~1000 people) through an online questionnaire (called "How Are You?"). (2) The secondintervention is an enriched version of the "How Are You?" Survey, which providespersonalized feedback about coping, interpersonal interactions and moral distress.Participants will be randomized (1:1) to receive the shorter Express Survey (identifyingdata and outcome measures only), or the Enriched survey (all of the Express measures plusadditional measures with feedback based on responses). It is hypothesized that both thePRC intervention and the Enriched Survey intervention will help prevent or reduceinstances of burnout in HCWs.

Patient are being asked to provide respiratory and blood samples for a clinical researchstudy because the patients have a virus called the novel coronavirus, or SARS-CoV-2, thatcauses the disease known as Covid-19.Investigators do not know a lot about this virus, including all the ways it travels fromperson to person. Investigators also do not know if a person will get sick or not fromthe virus after being in close contact with someone who has the virus. Because of this,investigators are performing research on the virus found in respiratory secretions to getmore information on how investigators can best detect and treat this new virus in thefuture.Primary Objective - To determine the clinical characteristics and outcomes of Covid-19 in children. - To characterize the clinical risk factors of Covid-19 in children..Secondary Objectives - To characterize the immunological risk factors and serologic response to SARS-CoV-2 infection in children.- To evaluate the duration of viral shedding in children. - To evaluate the duration of SARS-CoV-2 viral shedding in children. Exploratory Objective

The COVID-19 CHAMPS Study will obtain data on the physical and mental health andwell-being of workers potentially exposed to the SARS-CoV-2 virus in the course of theirduties. Included are a broad range of occupations including those working in thecommunity (police officers, firefighters, emergency personnel, screening staff) as wellas in permanent or temporary sites that care for patients (service staff, nurses,physicians and other health professionals). CHAMPS will obtain data on various exposurefactors and health and create a registry of participants for extended follow up andsub-studies.
