    Covid-19: Breastfeeding women can have vaccine after guidance turnaround

    11 Jan, 2021

    The UK’s Medicines and Healthcare Products Regulatory Agency (MHRA) has revised its guidance so that pregnant and breastfeeding women can receive the covid-19 vaccine.

    Writing in BMJ Opinion, Helen Hare, an acute medicine trainee, and Kate Womersley, an academic foundation trainee, said that the change had come after strong pressure from campaigners, clinicians, and some of the women affected.1

    The MHRA had previously recommended that breastfeeding women should not be g...

    Increased expression of hypoxia-induced factor 1α mRNA and its related genes in myeloid blood cells from critically ill COVID-19 patients

    28 Dec, 2020
    AbstractBackground
    COVID-19 counts 46 million people infected and killed more than 1.2 million. Hypoxaemia is one of the main clinical manifestations, especially in severe cases. HIF1α is a master transcription factor involved in the cellular response to oxygen levels. The immunopathogenesis of this severe form of COVID-19 is poorly understood.
    Methods
    We performed scRNAseq from leukocytes from five critically ill COVID-19 patients and characterized the expression of hypoxia-inducibl...

    The U.K. Coronavirus Mutation Is Worrying but Not Terrifying

    28 Dec, 2020
    There is evidence the new variant could be more transmissible, yet vaccines work very well against it
    A new mutated form of the novel coronavirus that appears more transmissible than the original has raised alarm in the U.K. and around the world. It does not appear to cause more severe disease, and the newly available vaccines do seem to protect people against it. Yet on December 19—after an announcement that the variant, dubbed B.1.1.7, had suddenly accumulated 17mutations and was spreadi...

    Afucosylated IgG characterizes enveloped viral responses and correlates with COVID-19 severity

    28 Dec, 2020
    Abstract
    IgG antibodies are crucial for protection against invading pathogens. A highly conserved N-linked glycan within the IgG-Fc tail, essential for IgG function, shows variable composition in humans. Afucosylated IgG variants are already used in anti-cancer therapeutic antibodies for their elevated activity through Fc receptors (FcγRIIIa). Here, we report that afucosylated IgG (~6% of total IgG in humans) are specifically formed against enveloped viruses but generally not against other...

    New saliva-based antibody test for SARS-COV-2 highly accurate in initial study

    24 Nov, 2020


    The test could prove useful for large-scale screening and epidemiological surveys and cuts down on reliance on blood draws


    A new saliva-based test developed by a team at Johns Hopkins Bloomberg School of Public Health has been found to accurately detect the presence of antibodies to SARS-CoV-2, the virus that causes COVID-19, from small samples of saliva. Such tests, the results of which can be obtained in a matter of hours, are seen as potential alternatives to blood-sampl...

    Face masks: what the data say

    10 Oct, 2020
    The science supports that face coverings are saving lives during the coronavirus pandemic, and yet the debate trundles on. How much evidence is enough?



    When her Danish colleagues first suggested distributing protective cloth face masks to people in Guinea-Bissau to stem the spread of the coronavirus, Christine Benn wasn’t so sure.

    “I said, ‘Yeah, that might be good, but there’s limited data on whether face masks are actually effective,’” says Benn, a global-health resear...

    Do some people have protection against the coronavirus?

    4 Aug, 2020

    We're now more than seven months into the coronavirus pandemic that has upended the lives of most of Earth's inhabitants. And while it is true that the scientific community has learned many things about the SARS-CoV-2 virus and the disease it causes, Covid-19, there are also many gaps in our understanding.
    One big mystery: Why do some people get very sick and even die from their illness, while other similar people show no symptoms and may not realize they've been infected at all?We kno...

    Achieving Technological Change Without Digital Fatigue

    21 Jul, 2020

    The COVID-19 pandemic has drastically accelerated the need for the advancement of healthcare’s digital transformation. The obligation to stay at home caused by the pandemic has sped up the transition from to face-to-face work to remote work through the use of digital technologies and web resources.

    Reliance on technology has negatively affected human attention, decision-making capacity, and emotional wellbeing - added to increased tension and lack of concentration. 31% of primary c...

    Questions raised over study claiming drug linked to higher rate of mortality and heart problems in Covid-19 patients


    The World Health Organization will resume clinical trials of an anti-malaria drug researchers hope may treat Covid-19, after a study of the drug published in May by a major medical journal prompted them to halt trials due to safety concerns.
