CORIA is an observational cohort study of immunosuppressed populations who test positivefor COVID-19. This includes people living with HIV, cancer, acquired immunodeficiencyassociated with other immunosuppressive therapy, primary immunodeficiency and recipientsof a solid organ transplant. Participants will have routine clinical data collected withoptional baseline collection and storage of a blood sample for storage . The study willbe conducted in up to 30 sites within Australia.

This is a retrospective/prospective, cohort, non-interventional observational study. Thismeans that all patients with documented COVID and HM diagnosed between February 2020 andstudy initiation will compose the retrospective part, while those diagnosed after studyapproval will enter prospective part.The total duration of the study will be 12 months.The study population will must be older than 18 years of age with HM and SARS-CoV-2infection. All patients with documented SARS-CoV-2 infection (COVID) and history oractive hematological malignancies, who refer to any Hematological Unit will be included.

There is an urgent need for targeted and effectiveCOVID-19 treatments which has put great pressure on researchers across the world fordeveloping effective drugs. In this clinical study we attempt to demonstrate Isotretinoincould be an effective and promising treatment for SARS-CoV-2 based on the intracellularmechanism of SARS-CoV-2 transmission and consequences caused. Isotretinoin could stronglyinhibit both inflammation and viral entry in severe acute respiratory syndromecoronavirus 2 infection via decreasing the overproduction of early responseproinflammatory cytokines (interleukin-6 ) which are over expressed in COVID-19 andcontributed to disease progression, poor outcomes, vascular hyper permeability andmultiorgan failure in patients infected with COVID-19. It could also block the entry ofCOVID-19 by inhibiting androgenic factors that induce serine 2 transmembrane protease(TMPRSS2) expressions.. In addition to inhibiting of Angiotensin-converting enzyme-2(ACE2), Angiotensin T1 protein and Angiotensin II-mediated intracellular calcium releasepathway which is responsible for COVID-19 cell fusion and entry, ACE2-expressing cellsare prone to SARS-CoV-2 infection as ACE2 receptor facilitates cellular viral entry andinvasion. Moreover, isotretinoin is a potential repressor and inhibitor of papain-likeprotease (PLpro), which is a lethal protein expressed by COVID-19 genes and is an enzymeof dubiquitination which facilitates virus replication in patients with COVID-19.Thegenome of Middle East Respiratory Syndrome Coronavirus is recognized by melanomadifferentiation-associated protein-5 (MDA5), retinoic acid inducible gene-1 (RIG-1) andendosomal toll-like receptor 3 (TLR3) as pathogen-associated molecular patterns. Thisrecognition resulted in the formation of type-1 interferon (IFN1). As an evasionmechanism, virus synthesize proteins that hinder the production IFN1 in the pathway.13-cis retinoic acid induced significant upregulation of toll-like receptor 3 (TLR3),mitochondrial antiviral-signaling protein (MAVS) and IFN regulatory factor 1 expressionin a time-dependent. Furthermore, 13 cis Retinoic Acid (13 cis RA) could be an effectiveand promising treatment for SARS-CoV-2 owing to its ability to increase CD4 cells andinduce mucosal IgA antibodies that are less prone to Antibody Dependent Enhancementprocess (ADE) and responsible for passive mucosal immunity in the respiratory tract. ADEis a phenomenon in which antiviral antibodies facilitate viral infection of target immunecells and, in some cases, make a second infection worse, such as dengue fever (denguevirus), By inducing IgA antibodies, 13 cis retinoic acid enhances mucosal immunity and isknown to be a potent IgA isotype.13 Cis retinoic acid induced significant upregulation oftoll-like receptor 3 an immune boosting action that may result in an immune response todsRNA intermediate leading to the production of type I IFNs which is important to enhancethe release of antiviral proteins for the protection of uninfected cells. Isotretinointherapy has furthermore proven anti-platelet and fibrinolytic activities which mayprotect patients infected with covid-19 from widespread blood clots. From this point, wesuggest that isotretinon will be the Immunity passport" in the context of COVID-19

A lot of people suffer from phobias. Phobias concerning certain diseases are not rare.This study will examine whether the COVID-19 (Coronavirus Disease) crisis was able torise phobias in people and if those with preexisting phobias or fears were more likely todevelop a phobia concerning COVID. It will look at different subtypes - physicians,medical staff, general public (not medically affiliated) and patients with psychiatricdisorders.

The purpose of the study is to confirm if BACTEK-R (MV130) provides clinical benefit insubject with mild pneumonia (CURB-65≤2) by COVID-19 admitted to the Hospital.

Mental health disorders are common during pregnancy and the postnatal period, and canhave serious adverse effects on the well-being of woman and child. Every tenth woman hasdepressive symptoms and 5% suffer major depression during pregnancy. The consequences forglobal mental health due to the novel coronavirus disease, COVID-19, are likely to besignificant and may have long-term impact on the global burden of disease. Pregnant womenmay be particularly vulnerable due to partial immune suppression. Besides physicalvulnerability, the women could be at increased risk of mental health problems, such asanxiety, depression, and post-traumatic stress disorder (PTSD), due to social distancingleading to less support from the family and friends, and in some cases, partners notbeing allowed to be present during prenatal visits, labor and delivery. Furthermore, manypregnant women may feel insecure and worried about the effect of COVID-19 on their unbornchild, if the women get infected during pregnancy. Today, young urban women are used toutilizing internet services frequently and efficiently. Therefore, providing mentalhealth support to pregnant women via web-based support may be effective in amelioratingtheir anxiety/depression and reduce the risk of serious mental health disorders leadingto improved maternal and perinatal outcomes.

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.
