COVID-19The objective of this study is to support the exploration of the NEURO-COVID-19 database and in particular to carry out the post-treatments necessary to derive quantitative information on the characterization of the lesion load, in particular with regard to of the vascular tree
Identification of Factors Associated With the Occurrence of Severe Forms of COVID-19 Infection in...
SARS-CoV2 InfectionRare Diseases2 moreFactors associated with severe forms of COVID-19 infection in patients with inflammatory rheumatic diseases (IRD) or Autoimmune Diseases (AID) are unknown. This unprecedented situation leads to empirical and potentially erroneous advice and recommendations for care. Identifying factors associated with severity, in the context of this pandemic, which is expected to last many months, and possibly years, is crucial for future patients. The objective of this work is to identify the factors associated with the occurrence of severe forms of COVID-19 infection in patients with IRD or AID, by combining analysis of 2 large databases.
Could Docosahexaenoic Acid (DHA), Contained in Breast Milk and Artificial Baby Milks, Protect Infants...
COVID19Could Docosahexaenoic Acid (DHA) Protect Infants and Children From COVID-19 and Make Them Less Susceptible to COVID-19-related Severe Illness Than Adults? The study is configured as a retrospective and prospective observational study. The study will be multi-center and will involve all Infants and Children feeding on breast milk or Artificial milk formula that contained on DHA. Human milk is the best form of infant nutrition providing significant protection against many illnesses for term and preterm infants. This study seeks to investigate the possible protective role of DHA found in Breast Milk or Artificial Milk Formula that are used for feeding of Children and Infants. This study would examine the electronic patient record of Newborn from birth to about 2 months of age and Infants from 2 months to 1 year old as well as children from 1year to age 5 years old , feeding on Breast Milk or Artificial Milk Formula between March 2020 and October 2021 and compare their rates of Covid-19 infection, hospitalization and complications with the rates of the local age-matched background population. As Covid-19 is a new disease, the existing research literature on this specific topic is extremely limited, and so far this study would be the first in this area. Abstract The novel SARS-CoV-2, which causes the disease called COVID-19, has rapidly spread across the globe. A striking and consistent observation has been the difference in severity of COVID-19 at different ages: severity, the need for hospitalization and mortality rise steeply with older age while severe disease and death are relatively rare in children and young adults. Most children infected with SARS-CoV-2 are asymptomatic or have mild symptoms, most commonly fever, cough, pharyngitis, gastrointestinal symptoms and changes in sense of smell or taste. Whether children are also less often infected by SARS-CoV-2 is an ongoing debate. Large epidemiological studies suggest that children comprise only 1 to 2% of all SARS-CoV-2 cases. However, these numbers heavily depend on testing criteria and, in many reports, testing was done only in individuals who were symptomatic or required hospitalisation, which is less often the case for children. Some studies suggest that children are just as likely as adults to become infected with SARS-CoV-2.9 However, more recent studies report that children are less likely to get infected after contact with a SARS-CoV-2-positive individual.10-14 It has been suggested that children and adolescents have similar viral loads and may therefore be as likely to transmit SARS-CoV-2 as adults. In addition, the viral load may be similar in asymptomatic and symptomatic individuals. However, reassuringly, transmission in schools from children either to other children or to adults has been rare. The observation that children are less often infected with SARS-CoV-2 and that they have less severe symptoms is similar to that reported for SARS-CoV-1 and Middle East respiratory syndrome (MERS)-CoV. However, this pattern is strikingly different to that for infection with most other respiratory viruses (eg, respiratory syncytial virus (RSV), metapneumovirus, parainfluenza or influenza viruses), for which the prevalence and severity are both higher in children. Dr Amr kamel khalil Ahmed and Dr. Mahmoud Elkazzaz, the lead investigators of this observational study , recently published a preprint that demonstrated Docosahexaenoic acid (DHA) had a high binding affinity and greatest interactions with ACE2 active sites, as well as a moderate binding affinity and moderate interactions with the active sites of IL-6. The Docosahexaenoic acid (DHA) interacts with different active sites of IL6 and ACE2 which are involved in direct or indirect contacts with the ACE2 and IL-6 receptors which might act as potential blockers of functional ACE2 and IL-6 receptor complex. Docosahexaenoic acid (DHA) was detected in abundance in breast milk and other algal sources milk supplement used for newborns and children's feeding. As a result, we believe that docosahexaenoic acid (DHA) may protect children and newborns thorough competing with COVID-19 for ACE2 receptors and inhibiting IL-6 activity and may possibly help them avoid a cytokine storm and save their lives through inhibiting IL-6 and preventing SARS-CoV-2 RBD attachment to ACE2

Changes in Physical Activity Status: Comparison of Older Adults With Versus Without a History of...
Covid19The negative impact of the Covid-19 pandemic on the physical activity behavior of overall adults has been reported. But much less is known in older adults. Alterations in physical activity among Covid-19 survivors have not been investigated so far. The present study aimed to evaluate the physical activity status of older adults in terms of a history of Covid-19 infection.
Functional Capacity in Survivors of COVID-19 Related ARDS
Covid19Functional Capacity1 moreAcute respiratory distress syndrome survivors frequently develop impaired physical function, muscle weakness and quality of life. The aim of this retrospective study is to determine the functional capacity, global muscle weakness and quality of life of COVID-19 survivors after 4 weeks following hospital discharge and the relationship between different tools. COVID-19 related acute respiratory distress syndrome survivors were assessed 4 weeks following discharge from the hospital, 15 patients who attended the evaluation will be included the study. All subjects underwent standardized physical clinical evaluation, Medical Research Council-sumscore, hand-grip strength, 6-minute walk test, chair-stand test, timed up and go test and Short form-36, 4 weeks after hospital discharge.
WhatsApp in India During the COVID-19 Pandemic
Covid19Digital misinformation has been flagged as a major risk of the 21st century, with an estimated cost of $78 billion to the global economy each year. Given this scope, we propose to characterize how misinformation is spread via messenger platforms (e.g. WhatsApp). Specifically, we seek to: Identify metrics of potential misinformation (Aim 1). This is based on the hypothesis that although message contents are highly private, proxy markers can be used to identify potential misinformation. Understand the base-rate by which misinformation is shared via messaging applications (Aim 2). This is founded on the hypothesis that misinformation is endemic on messaging platforms, and thus needs to be documented. Identify "super spreaders" responsible for sending and receiving a large volume of misinformation (Aim 3). Here, we hypothesise that a small group of super spreaders are responsible for the bulk of misinformation-sharing on messaging applications. The thrust of this work aligns with both government priorities and the grant's thematic areas, providing actionable findings that are timely amidst a worldwide surge of misinformation.

Serological Response to mRNA and Inactivated COVID-19 Vaccine in Health Care Workers in Hong Kong...
Covid-19 VaccineSince the first local case of COVID-19 confirmed on 4 Feb 2020, Hong Kong has already experienced 4 waves of COVID-19 surge, with more than 9000 cases reported. A number of vaccines have been shown to be efficacious against symptomatic and severe infection by inducing neutralizing antibody (NAB) against spike protein of the SARS-CoV-2 virus. However, the duration of protection and longevity of antibody response is unknown. Health care workers (HCWs) who are planning to receive COVID-19 vaccine will be recruited. The level of antibody against spike protein by different quantitative assays will also be serially measured .
