The purpose of this study is to characterize the incidence and clinical features of thematernal COVID 19 infection, as well as the associated morbidity of the mother and thechild, in the French context

The Canadian Paediatric Society recommends breastfeeding during COVID-19 infection. Humanmilk is the best form of infant nutrition providing significant protection against manyillnesses for term and preterm infants. When mothers of hospitalized infants are unableto supply their milk, the recommended supplement is human donor milk. The impact of apandemic on human milk banking is unknown. This study seeks to address this public healthissue. Donor milk will be collected from the Rogers Hixon Ontario Human Milk Bank atSinai Health System in Toronto. Samples will be analyzed for the COVID-19 virus specificnucleic acid and antibody in real-time and results will be immediately disseminated torelevant organizations to inform local, national and international guidelines surroundingdonor milk banking to protect the health of infants.

This is a phase 1/2a study including 2 parts, phase 1 and phase 2a. The phase 1 part isan open-label, single-arm, dose-escalating study to evaluate the safety and explore thedose limiting toxicity and maximum tolerated dose of a human umbilical cord derivedmesenchymal stem cell product (BX-U001) in severe COVID-19 pneumonia patients with acuterespiratory distress syndrome (ARDS). Qualified subjects after the screening will bedivided into low, medium, or high dose groups to receive a single intravenous infusion ofBX-U001 at the dose of 0.5×10^6, 1.0×10^6, or 1.5×10^6 cells/kg of body weight,respectively. The Phase 2a part is a randomized, placebo-controlled, double-blindclinical trial examining the safety and biological effects of BX-U001 at the appropriatedose selected from phase 1 for severe COVID-19 pneumonia patients with the sameinclusion/exclusion criteria as the phase 1 part.

This study uses questionnaires to gain an understanding of how experiences during theCOVID-19 pandemic, regardless of COVID-19 status, may have impacted health-relatedquality of life (HRQOL) and other areas such as COVID-19-specific psychological distress,disruptions to health care, finances and social interactions in cancer patients. Thecoronavirus disease 2019 (COVID-19) is an infectious disease that is caused by the severeacute respiratory syndrome coronavirus 2 (SARS-CoV-2). The information learned from thisstudy will guide the development of psychosocial programs to improve patient care andoutcomes in cancer patients and survivors in the context of facing a global pandemic.

We aim to understand the mechanism of olfactory dysfunction in COVID-19.

There is a pandemic in the world by COVID-19. Currently, the pharmacological curative orprophylactic treatments for this infection are not known. Recent studies have suggestedthat Hydroxy-Chloroquine could be effective in vitro and in vivo against COVID-19. Themain objective of this study is to assess in patients with autoimmune disease treatedwith long course Hydroxy-Chloroquine initiated before the pandemic COVID-19 had anindependent protective effect on the risk or the severity of infection with COVID-19.

This phase I trial investigates breathing techniques and meditation for health careworkers during COVID-19 pandemic. Breathing techniques and medication may help managestress and improve lung health. The goal of this trial is to learn if breathingtechniques and meditation may help to reduce stress and improve lung health in healthcare workers during the COVID-19 pandemic.

Postpartum depression (PPD) represent around 15% of birth in developed countries. Thecontext of the COVID-19 epidemy represents a possible source of additional emotionaldistress. The objective of this study is to determine the screening prevalence and riskfactors of postpartum depression, among women who deliver in fourth hospital in the Northof France in the context of the COVID epidemy.

Recent studies have shown that some individuals may be asymptomatic but continue to shedthe COVID-19 virus. These individuals may represent a population that can unknowinglytransmit the virus. Healthcare workers (HCW) may acquire COVID-19 from the community orfrom possibly infected patients. It is important to gather data with respect to this tofurther understand the prevalence of asymptomatic carriage in individuals who work inresearch facilities, offices and clinical areas of hospitals and researchfacilities/institutes since this has important implications for infection control, aswell as staff and patient safety. The purpose of this study is to test whether aproportion of these individuals may be asymptomatic shedders of the COVID-19 virus.
