In the early months of the COVID-19 pandemic, healthcare workers analyzing test results began noticing something strange: patients who had already recovered from COVID-19 would sometimes inexplicably test positive on a PCR test weeks or even months later. Although people can catch COVID-19 for a second time, this did not appear to be the case
Pfizer and BioNTech’s coronavirus reduces the risk of getting sick from COVID-19 by five- to 30-fold for fully immunized people, two new studies show. In one report, just 0.4 percent of healthcare workers in Israel who received both shots of the COVID-19 immunization later tested positive compared to 7.2 percent of unvaccinated employees. This means healthcare workers who
Moderna said its COVID-19 vaccine is 96 percent effective among youths aged 12 to 17, according to the results of its first clinical trials. Two-thirds of the 3,235 participants in trials in the United States received the vaccine and one-third were given a placebo. The study “showed vaccine efficacy against COVID-19 of 96%; mRNA-1273 was generally well
Norwegian and Danish researchers published a register study in BMJ of over 281,000 people who have received the AstraZeneca vaccine. – The study confirms previous findings from OUS and internationally. The registry study finds 11 additional cases of venous thrombosis among 100,000 vaccinated. The article that follows people who have received the AstraZeneca vaccine in
A new study is drawing the most detailed picture yet of SARS-CoV-2 infection in the lung, revealing mechanisms that result in lethal COVID-19, and may explain long-term complications and show how COVID-19 differs from other infectious diseases. Led by researchers at Columbia University Vagelos College of Physicians and Surgeons and Herbert Irving Comprehensive Cancer Center, the study found
In a major shot in the arm for the Pfizer-BioNTech COVID-19 vaccine, researchers have reported in two studies that it is highly effective in protecting against severe COVID-19 infections caused by the variants first reported in the UK and South Africa. In a study published in the New England Journal of Medicine on May 5, researchers analysed
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus is highly contagious and causes lymphocytopenia, but the underlying mechanisms are poorly understood. In this paper published on Nature fresearchers of Laboratory of Cell Engineering, Institute of Biotechnology, Beijing, China demonstrate that heterotypic cell-in-cell structures with lymphocytes inside multinucleate syncytia are prevalent in the lung tissues
A study published in July 2020 hypothesized a link between the presence of bradykinin, a well-known peptide, and severe cases of COVID-19. Vardan Karamyan, Ph.D., an associate professor and vice chair for the Texas Tech University Health Sciences Center (TTUHSC) Jerry H. Hodge School of Pharmacy Department of Pharmaceutical Sciences, had not previously conducted or
In the search for treatments for COVID-19, many researchers are focusing their attention on a specific protein that allows the virus to infect human cells. This protein, which cells carry on their surface, is called angiotensin converting enzyme 2 (ACE2) and provides the entry point for the coronavirus to enter cells. ACE2 is present in
COVID-19 is associated with a high incidence of thrombotic complications, which can be explained by the complex and unique interplay between coronaviruses and endothelial cells, the local and systemic inflammatory response, and the coagulation system. Empirically, an intensified dose of thrombosis prophylaxis is being used in patients admitted to hospital with COVID-19 and several guidelines
Clinical trials have shown the COVID-19 vaccines now being administered around the country are highly effective in protecting fully vaccinated individuals from the coronavirus SARS-CoV-2. But will they continue to offer sufficient protection as the frequency of more transmissible and, in some cases, deadly emerging variants rise? More study and time is needed to fully
Spinal fusion is frequently performed to restore spinal stability in patients with spinal diseases, such as spinal stenosis, vertebral fractures, progressive deformities, and instability. In the past two decades, there has been marked increase in the number of people over 65 years in age who have needed spinal fusion surgery. While autogenous bone grafts have
Cerebral venous sinus thrombosis (CVST) with thrombocytopenia, a rare and serious condition, has been described in Europe following receipt of the ChAdOx1 nCoV-19 vaccine (Oxford/AstraZeneca), which uses a chimpanzee adenoviral vector. A mechanism similar to autoimmune heparin-induced thrombocytopenia (HIT) has been proposed. In the US, the Ad26.COV2.S COVID-19 vaccine (Janssen/Johnson & Johnson), which uses a
In recent years, the interest in adipose tissue mesenchymal cell–derived extracellular vesicles (AT-MSC-EVs) has increasingly grown. Numerous articles support the potential of human AT-MSC-EVs as a new therapeutic option for treatment of diverse diseases in the musculoskeletal and cardiovascular systems, kidney, skin, and immune system, among others. This approach makes use of the molecules transported
Researchers have found that a natural molecule can effectively block the binding of a subset of human antibodies to SARS-CoV-2. The discovery may help explain why some COVID-19 patients can become severely ill despite having high levels of antibodies against the virus. In their research, published in Science Advances today (22 April 2021), teams from the Francis
The National Institutes of Health has made significant updates to its guidelines on treating people with COVID-19. What’s New in the Guidelines Last Updated: April 21, 2021 The Coronavirus Disease 2019 (COVID-19) Treatment Guidelines is published in an electronic format that can be updated in step with the rapid pace and growing volume of information regarding the
Chimeric antigen receptor (CAR) T-cell therapy can induce side-effects such as cytokine release syndrome and immune effector cell-associated neurotoxicity syndrome (ICANS), which often require intensive care unit admission. The aim of the study, published in The Lancet Haematology was to describe management of critically ill CAR T-cell recipients in intensive care. An international, multicentre, observational
Research has shown that people with red hair perceive pain differently than others. They may be more sensitive to certain types of pain and can require higher doses of some pain-killing medications. However, studies suggest that their general pain tolerance may be higher. People with red hair also respond more effectively to opioid pain medications,
COVID-19, caused by SARS-CoV-2 virus infection, has changed human behavior patterns since it became a global pandemic. To date, more than 136 million people have suffered from the disease and, of these, more than 2.9 million have lost their lives. The symptoms of the infection vary widely, from individuals who show no clinical symptoms to those who
Cases of unusual thrombosis and thrombocytopenia after administration of the ChAdOx1 nCoV‐19 vaccine (AstraZeneca) have been reported. The term vaccine‐induced prothrombotic immune thrombocytopenia (VIPIT) was coined to reflect this new phenomenon. In vitro experiments with VIPIT patient sera indicated that high dose intravenous immunoglobulins (IVIG) competitively inhibit the platelet activating properties of ChAdOx1 nCoV‐19 vaccine induced
In a paper recently published on Cell, an emerging SARS-CoV-2 variant was identified by viral whole-genome sequencing of 2,172 nasal/nasopharyngeal swab samples from 44 counties in California, a state in the Western United States. Named B.1.427/B.1.429 to denote its 2 lineages, the variant emerged in May 2020 and increased from 0% to >50% of sequenced
At its meeting of 20 April 2021, EMA’s safety committee (PRAC) concluded that a warning about unusual blood clots with low blood platelets should be added to the product information for COVID-19 Vaccine Janssen. PRAC also concluded that these events should be listed as very rare side effects of the vaccine. In reaching its conclusion, the Committee took into
For weeks, Americans looked on as other countries grappled with case reports of rare, sometimes fatal blood abnormalities among those who had received the AstraZeneca vaccine against COVID-19. That vaccine has not yet been authorized by the FDA, so restrictions on its use throughout Europe did not get that much attention in the United States.
Precision medicine is, broadly speaking, a sweeping aspiration that will be achieved, or not, depending on the convergence of many different disciplines. The most important of these disciplines are molecular genetics and cell biology. Besides contributing to precision medicine directly, they also contribute through 3D bioprinting. In 3D bioprinting, molecular genetics and cell biology are
The mainstay of control of the coronavirus disease 2019 (Covid-19) pandemic is vaccination against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Within a year, several vaccines have been developed and millions of doses delivered. Reporting of adverse events is a critical postmarketing activity. In this paper are reported findings in 23 patients who presented with
Despite progress in clinical care for patients with coronavirus disease 2019 (COVID-19), population-wide interventions are still crucial to manage the pandemic, which has been aggravated by the emergence of new, highly transmissible variants. In this study, we combined the SIDARTHE model, which predicts the spread of SARS-CoV-2 infections, with a newdata-based model that projects new
Researchers at the University of Oxford have today reported that the risk of the rare blood clotting known as cerebral venous thrombosis (CVT) following COVID-19 infection is around 100 times greater than normal, several times higher than it is post-vaccination or following influenza. The study authors, led by Professor Paul Harrison and Dr Maxime Taquet

A team led by investigators at Weill Cornell Medicine and NewYork-Presbyterian has used advanced technology and analytics to map, at single-cell resolution, the cellular landscape of diseased lung tissue in severe COVID-19 and other infectious lung diseases. In the study, published online March 29 in Nature, the researchers imaged autopsied lung tissue in a way that
Cerebral venous sinus thrombosis (CVST) occurs when a blood clot forms in the brain’s venous sinuses. This prevents blood from draining out of the brain. As a result, blood cells may break and leak blood into the brain tissues, forming a hemorrhage. This chain of events is part of a stroke that can occur in adults
Increased understanding of whether individuals who have recovered from COVID-19 are protected from future SARS-CoV-2 infection is an urgent requirement. In a paper published on The Lancet it was investigated whether antibodies against SARS-CoV-2 were associated with a decreased risk of symptomatic and asymptomatic reinfection. A large, multicentre, prospective cohort study was done, with participants
We wish to raise our concern with the MHRA regarding wording included in recent changes in MHRA guidance on the use of the AstraZeneca COVID-19 vaccine. The MHRA Guidance issued 7th April 2021 (https://www.gov.uk/government/news/mhra-issues-new-advice-concluding-a-possible-link-between-covid-19-vaccine-astrazeneca-and-extremely-rare-unlikely-to-occur-blood-clots ) Indicates: The MHRA is not recommending age restrictions in COVID-19 Vaccine AstraZeneca use.

SARS-CoV-2 showed the world with devastating clarity the threat undetected viruses can pose to global public health. SpillOver, a new web application developed by scientists at the University of California, Davis, and contributed to by experts from all over the world, ranks the risk of wildlife-to-human spillover for newly discovered viruses. SpillOver is the first open-source risk
NIH research suggests protective effects of vaccination remain intact When variants of SARS-CoV-2 (the virus that causes COVID-19) emerged in late 2020, concern arose that they might elude protective immune responses generated by prior infection or vaccination, potentially making re-infection more likely or vaccination less effective. To investigate this possibility, researchers from the National Institute

As devastating as this pandemic has been, it’s truly inspiring to see the many innovative ways in which researchers around the world have enlisted the help of everyday citizens to beat COVID-19. An intriguing example is the COVID Symptom Study’s smartphone-based app, which already has been downloaded millions of times, mostly in the United States
NIH-funded findings point to a role for saliva in SARS-CoV-2 transmission. An international team of scientists has found evidence that SARS-CoV-2, the virus that causes COVID-19, infects cells in the mouth. While it’s well known that the upper airways and lungs are primary sites of SARS-CoV-2 infection, there are clues the virus can infect cells
Study shows that antibody longevity varies widely from 40 days to as long as several decades and not everyone who has recovered from COVID-19 is immune from reinfection Individuals with low levels of neutralising antibodies may still be protected if they have robust T-cell immunity Blood tests and a computer algorithm suggest annual vaccinations might
Key Takeaways A single injection of a gene therapy involving what are called zinc fingers dramatically reduced levels of tau, a protein implicated in Alzheimer’s disease, in mice with the condition. The treatment was long lasting, caused no side effects, and reduced Alzheimer’s-related damage in the brain. The technology worked just the way we had
Gene therapy can be used to restore cell function in monogenic disorders or to endow cells with new capabilities, such as improved killing of cancer cells, expression of suicide genes for controlled elimination of cell populations, or protection against chemotherapy or viral infection. While gene therapies were originally most often used to treat monogenic diseases
Chimeric antigen receptor (CAR)-T cell therapies are on the verge of becoming powerful immunotherapeutic tools forcombating hematological diseases confronted with pressing medical needs. Lately, CAR-NK cell therapies have also come into focus as novel therapeutic options to address hurdles related to CAR-T cell therapies, such as therapy-induced side effects. Currently, more than 500 CAR-T and
Late Monday, the Data and Safety Monitoring Board (DSMB) notified NIAID, BARDA, and AstraZeneca that it was concerned by information released by AstraZeneca on initial data from its COVID-19 vaccine clinical trial. The DSMB expressed concern that AstraZeneca may have included outdated information from that trial, which may have provided an incomplete view of the

A study recently published in the journal Science looked into how CAR T immunotherapy could be used to treat solid tumours in addition to leukaemias. The programming of CAR T cells opens avenues for applying cell therapies to, for example, breast cancer or ovarian cancer in the future. In cancer immunotherapy, cells in the patient’s
From the early days of the COVID-19 pandemic, a distinct coagulation disturbance of SARS-CoV-2 infection has been recognized. This thrombo-inflammatory phenotype, characterized by endotheliopathy, hypercoagulability, and coagulation activation, results in an increased risk of thromboembolic events. Initial observational cohort studies described high rates of venous thromboembolism (VTE) in critically ill patients with COVID-19, despite consistent use
In The Lancet, Zhenyu He and colleagues report their cross-sectional study of serological responses of morethan 9500 individuals from 3600 households in Wuhan, the early epicentre for the COVID-19 outbreak. The study was initiated shortly after lockdown in Wuhan ceased in April, 2020, with follow-up over two timepoints (June and October–December, 2020). In this cross-sectional,
CDC’s national genomic surveillance program identifies new and emerging SARS-CoV-2 variants to determine implications for COVID-19 diagnostics, treatments, or vaccines authorized for use in the United States. Monitoring the spread of emerging variants in the United States relies on widespread, rapid sequencing. To accelerate sequencing in the United States, CDC has contracted with commercial diagnostic laboratories, and,
EMA’s safety committee, PRAC, concluded its preliminary review of a signal of blood clots in people vaccinated with COVID-19 Vaccine AstraZeneca at its extraordinary meeting of 18 March 2021. The Committee confirmed that: the benefits of the vaccine in combating the still widespread threat of COVID-19 (which itself results in clotting problems and may be fatal)
Thrombosis affecting the pulmonary and systemic vasculature is common during severe COVID-19 and causes adverse outcomes. Although thrombosis likely results from inflammatory activation of vascular cells, the mediators of thrombosis remain unconfirmed. In a cross-sectional cohort of 36 severe COVID-19 patients, it was shown that markedly increased plasma von Willebrand factor (VWF) levels were accompanied
The main hypothesis of this retrospective study is that VWF biomarkers are associated with coagulation in COVID-19. It was performed a balanced retrospective study of COVID-19 hospitalized patients with similar demographics and comorbidities and a wide range of D-dimer levels to study how VWF biomarkers correlate with coagulation, intravascular hemolysis, and outcome. Indeed, we show
Researchers from Cleveland Clinic’s Florida Research and Innovation Center (FRIC) have identified a potential new target for anti-COVID-19 therapies. Their findings were published in Nature Microbiology. Led by FRIC scientific director Michaela Gack, Ph.D., the team discovered that a coronavirus enzyme called PLpro (papain-like protease) blocks the body’s immune response to the infection. More research is necessary, but the
The SARS-CoV-2 spike gene has accumulated mutations within the receptor-binding domain (RBD) and the N-terminal domain (NTD). These domains are major targets of the antibody response elicited by the vaccines. The RBD mutations include the N501Y mutation, which is associated with increased affinity of SARS-CoV-2 to the angiotensin-converting enzyme 2 (ACE2) receptor. In contrast, the E484K
A number of European nations, including Germany, France, Italy and Sweden, have suspended use of the Oxford/AstraZeneca covid‑19 vaccine over blood clot concerns. The World Health Organization and the European Medicines Agency (EMA) have both emphasised that there is currently no evidence linking the vaccine to blood clots and recommend that countries continue using it. Emer Cooke, director of
Restrictions put in place to contain COVID-19 may be particularly difficult for teens, who rely heavily on their peer and social connections for emotional support. In 2021, the C.S.

Roy H. Perlis, M.D., from
The coronavirus disease-19 (COVID-19) pandemic has cost lives and economic hardships globally. Various studies have found a number of different factors, such as hyperinflammation and exhausted/suppressed T cell responses to the etiological SARS coronavirus-2 (SARS-CoV-2), being associated with severe COVID-19. However, sieving the causative from associative factors of respiratory dysfunction has remained rudimentary. In this
Key Takeaways Neutralizing antibodies induced by the Pfizer and Moderna COVID-19 vaccines were significantly less effective against the variants first described in Brazil/Japan and South Africa. While the ability of these variants to resist neutralizing antibodies is concerning, it doesn’t mean the vaccines won’t be effective. Understanding which mutations are most likely to allow the
The risk for invasive mechanical ventilation, hospitalization and death in those with COVID-19 increased with BMI, according to research published in MMWR. “The findings in this report highlight a dose-response relationship between higher BMI and severe COVID-19–associated illness and underscore the need for progressively intensive illness management as obesity severity increases,” LyudmylaKompaniyets, PhD, a postdoctoral research fellow at the CDC,
There are no therapeutics available that have been developed for COVID-19 treatment. Repurposing of already available medication for COVID-19 therapy is an attractive option to shorten the road to treatment development. The drug Camostat could be suitable. Camostat exerts antiviral activity by blocking the protease TMPRSS2, which is used by SARS-CoV-2 for entry into cells.

Vaccines to prevent COVID-19 infection are crucial for an effective global pandemic response. In The Lancet, Merryn Voysey and colleagues report the updated primary efficacy results for the Oxford–AstraZeneca ChAdOx1 nCoV-19 (AZD1222) vaccine from three single-blind, randomised controlled trials in the UK and Brazil and one double-blind study in South Africa. A subsequent report of
A variant of SARS-CoV-2 that emerged in southeast England in November 2020 is more transmissible than pre-existing variants, a new modeling study of Centre for Mathematical Modelling of Infectious Diseases, London School of Hygiene and Tropical Medicine, published on Science, finds. Further analyses suggest the variant B.1.1.7 will lead to large resurgences of COVID-19 cases.
All current vaccines for COVID-19 utilize ancestral wild type SARS-CoV-2 Spike with the goal of generating protective neutralizing antibodies. The recent emergence and rapid spread of several SARS-CoV-2 variants carrying multiple Spike mutations raise concerns about possible immune escape. One variant, first identified in the United Kingdom (B.1.1.7, also called 501Y.V1 or 20I), contains eight
“The Janssen COVID-19 vaccine is a very welcome addition to the arsenal of COVID-19 vaccines and other prevention strategies. When tested among 45,000 volunteers, the single-injection vaccine proved 77 percent effective in preventing severe/critical COVID-19 occurring at least 14 days after vaccination and 85 percent effective in preventing severe/critical COVID-19 occurring at least 28 days
Laboratory experiments have shown mouthwash can quickly kill coronaviruses, but there’s no evidence mouthwash can prevent the virus from infecting people. The Adams School of Dentistry is investigating how well mouthwash works to reduce the amount of SARS-CoV-2. Researchers at the University of North Carolina at Chapel Hill Adams School of Dentistry have launched a clinical trial to test
The Pfizer BioNTech coronavirus vaccine produces as good results in the “real world” as have been previously documented in randomised trials. A case control study, which has been peer reviewed and published in the New England Journal of Medicine, compared 596 618 people who were newly vaccinated in Israel and matched them to unvaccinated controls. Two doses
Infection by the new corona virus strain SARS-CoV-2 and its related syndrome COVID-19 has been associated with more than two million deaths worldwide. Patients of higher age and with preexisting chronic health conditions are at an increased risk of fatal disease outcome. However, detailed information on causes of death and the contribution of pre-existing health
People who have had evidence of a prior infection with SARS-CoV-2, the virus that causes COVID-19, appear to be well protected against being reinfected with the virus, at least for a few months, according to a newly published study from the National Cancer Institute (NCI). This finding may explain why reinfection appears to be relatively rare,
The Food and Drug Administration’s staff released a briefing document on Wednesday endorsing Johnson & Johnson’s one-shot coronavirus vaccine as safe and effective. An FDA advisory panel will meet Friday to review the briefing document and vote on whether to recommend an emergency use authorization (EUA). The FDA could then issue the (EUA) as soon as this
The 501Y.V2 variants of SARS-CoV-2 containing multiple mutations in Spike are now dominant in South Africa and are rapidly spreading to other countries. In this paper, experiments with 18 pseudotyped viruses showed that the 501Y.V2 variants do not confer increased infectivity in multiple cell types except for murine ACE2-overexpressing cells, where a substantial increase in
The race to produce vaccines against SARS-CoV-2 began when the first sequence was published, and this forms the basis for vaccines currently deployed globally. Independent lineages of SARS-CoV-2 have recently been reported: UK–B.1.1.7, South Africa–B.1.351 and Brazil–P.1. These variants have multiple changes in the immunodominant spike protein which facilitates viral cell entry via the Angiotensin

Editorial emphasizes need for global response. The rise of several significant variants of SARS-CoV-2, the virus that causes COVID-19, has attracted the attention of health and science experts worldwide. In an editorial published today in JAMA: The Journal of the American Medical Association, experts from the National Institute of Allergy and Infectious Diseases (NIAID), part of the
In drug development, scientific progression was never a solo effort. Rather, to advance new therapies, particularly cell and gene therapies, drug development is a team sport. Why is the team so important? Oftentimes when one tests novel cell and gene therapies in the clinic for the first time, one is treading completely new ground. The
Characterization of the humoral response to SARS-CoV-2, the etiological agent of COVID-19, is essential to help control the infection. The neutralization activity of plasma from COVID-19 patients decreases rapidly during the first weeks after recovery. However, the specific role of each immunoglobulin isotype in the overall neutralizing capacity is still not well understood. In this
Countering COVID-19 mutations and designing updated vaccines could occur at lightning speeds thanks to a new, USC-developed AI framework. USC researchers have developed a new method to counter emergent mutations of the coronavirus and hasten vaccine development to stop the pathogen responsible for killing thousands of people and ruining the economy. Using artificial intelligence (AI),
The Pfizer / BioNTech vaccine is effective against covid-19 variants originating in the UK and South Africa. This is the result of a study published this Monday in Nature Medicine , which showed better results in the first case, the British variant (called B.1.1.7), than in the second, the South African, or B.1.351. The differences, however, are small.
A clinical study led by Dr. Jordan Feld, a liver specialist at UHN’s Toronto Centre for Liver Disease, showed an experimental antiviral drug can significantly speed up recovery for COVID-19 outpatients – patients who do not need to be hospitalized. This could become an important intervention to treat infected patients and help curb community spread,
Breyanzi demonstrated a 73% overall response rate and 54% complete response (CR) rate in the largest pivotal trial in 3L+ LBCL, TRANSCEND NHL 001 trial Breyanzi demonstrated sustained responses in patients who achieved a CR with median duration of response not reached Grade ≥3 cytokine release syndrome and Grade ≥3 neurologic toxicities following Breyanzi treatment occurred in 4% and
SARS-CoV-2 mutations similar to those in the B1.1.7 UK variant could arise in cases of chronic infection, where treatment over an extended period can provide the virus multiple opportunities to evolve, say scientists. Writing in Nature, a team led by Cambridge researchers report how they were able to observe SARS-CoV-2 mutating in the case of an
What do we know about the E484K mutation? The E484K mutation is not a new variant in itself, it’s a mutation which occurs in different variants and has already been found in the South African (B.1.351) and Brazilian (B.1.1.28) variants. The mutation is in the spike protein and appears to have an impact on the
COVID-19 is a current global health threat caused by the novel coronavirus SARS-CoV-2. Emerging evidence indicates that SARS-CoV-2 elicits a dysregulated immune response and a delayed interferons (IFNs) expression in patients, which contribute largely to the viral pathogenesis and development of COVID-19. However, underlying mechanisms remain to be elucidated. In this paper, it’s reported the
The Johannesburg Witwatersrand University Vaccines and Infectious Diseases Analytics (VIDA) Research Unit, which runs the Oxford Covid-19 vaccine trial in South Africa, has announced results. In an analysis, submitted as a pre-print prior to peer-review publication, a two-dose regimen of the ChAdOx1 nCoV-19 vaccine provides minimal protection against mild-moderate COVID-19 infection from the B.1.351 coronavirus
The Janssen Pharmaceutical Companies of Johnson & Johnson announced today that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) will perform an accelerated assessment of the Marketing Authorisation Application (MAA) for the B-cell maturation antigen (BCMA)-targeted chimeric antigen receptor T-cell (CAR-T) therapy ciltacabtagene autoleucel (cilta-cel). Accelerated assessment is
A more contagious variant of the coronavirus first found in Britain is spreading rapidly in the United States, doubling roughly every 10 days, according to a new study. Analyzing half a million coronavirus tests and hundreds of genomes, a team of researchers predicted that in a month this variant could become predominant in the United States,
We need open data, especially open SARS-CoV-2 sequence data, and open science to beat COVID-19 and to prepare for future outbreaks. Why open data is so important When responding to a health crisis, data play a critical role in understanding transmission, infection and symptoms, and in identifying drug targets, developing vaccines and designing public health
Since B.1.1.7 was first identified in September in southern England, it has become the dominant variant in the United Kingdom and has spread to more than 30 countries. To investigate whether the lineage causes an increased risk of dying, Nicholas Davies, an epidemiologist at the LSHTM, and colleagues analysed data from more than 850,000 people
There are several approved treatments for coronavirus disease 2019 (COVID-19) in hospitalized patients but few for patients who are not sick enough to be hospitalized. Monoclonal antibodies are a new treatment for outpatients with COVID-19 who are at risk of progression to severe disease. What Is a Monoclonal Antibody? An antibody is a protein that is naturally
The US Food and Drug Administration (FDA) revised its emergency use authorization (EUA) for COVID-19 convalescent plasma to limit its use to high titer units and only in hospitalized patients who are in the early stages of the disease or who have impaired humoral immunity. Convalescent plasma emerged as a potential treatment for COVID-19 in the
Using patient data, artificial intelligence can make a 90 percent accurate assessment of whether a person will die from COVID-19 or not, according to new research at the University of Copenhagen. Body mass index (BMI), gender and high blood pressure are among the most heavily weighted factors. The research can be used to predict the
In a recent paper, the research team around Prof. Antonio del Sol from the University’s Luxembourg Centre for Systems Biomedicine (LCSB) describes a new method of how molecules can be identified that amplify and maintain the inflammatory response upon an infection. They use their novel method to identify these molecules in COVID-19 patients and suggest new
How do vaccines work? Germs are all around us, both in our environment and in our bodies. When a person is susceptible and they encounter a harmful organism, it can lead to disease and death. The body has many ways of defending itself against pathogens (disease-causing organisms). Skin, mucus, and cilia (microscopic hairs that move debris away
The COVID-19 pandemic continues to constitute a huge threat to public health worldwide and despite the efforts and advances to untangle the mechanisms of SARS-CoV-2 infection and transmission among humans, we are still blind to the overall COVID-19 pathology and its consequences. The results presented in this paper might help understand the emergent erythropoiesis and
A new study by Yale researchers found a significant association between the availability of hospital resources — particularly ICU beds — and patient mortality during the early weeks of the COVID-19 pandemic. This was especially true at hospitals in the northeastern U.S. which were hardest hit by the first surge of patient cases, according to
What is RNA? How do mRNA vaccines work, and how effective are they? What does this mean for the COVID-19 pandemic? In a short video, Yale experts Saad Omer, Onyema Ogbuagu, and Akiko Iwasaki explain the science.
Chimeric antigen receptor T-cell therapy, or CAR T, has been a breakthrough in the treatment of blood cancers such as acute lymphoblastic leukemia and diffuse large B-cell lymphoma. Clinical studies have shown overall response rates of more than 80% with an ongoing response of nearly 40% more than two years after therapy. However, the cellular
A Russian vaccine against COVID-19 — Gam-COVID-Vac (dubbed “Sputnik V”) — shows 92% efficacy in interim results from a phase 3 trial reported in The Lancet. The two-dose vaccine uses replication-deficient adenoviruses to deliver a SARS-CoV-2 glycoprotein as the antigenic stimulus. Doses are administered at 21-day intervals, and the vaccine may be stored in normal freezers.
The ChAdOx1 nCoV-19 (AZD1222) vaccine has been approved for emergency use by the UK regulatory authority, MHRA, with a regimen of two standard doses given with an interval of between 4 and 12 weeks. The planned rollout in the UK will involve vaccinating people in high risk categories with their first dose immediately, and delivering
In one of the most puzzling and worrisome developments in the pandemic, scientists are racing to explain what’s happening in Manaus, Brazil, a city of 2.2 million at the edge of the country’s rainforest that is experiencing a second explosive outbreak, even though the first one was so bad it was thought to have produced
People infected with the new variant of covid-19 discovered in the South East of England (known as B.1.1.7 or VUI 202012/01) are more likely to have a cough, sore throat, fatigue, or myalgia than those infected with other variants, the Office for National Statistics has reported. The data, published 27 January, also show that people
Researchers at the University of Arizona are developing a COVID-19 testing method that uses a smartphone microscope to analyze saliva samples and deliver results in about 10 minutes. The UArizona research team, led by biomedical engineering professor Jeong-Yeol Yoon, aims to combine the speed of existing nasal swab antigen tests with the high accuracy of nasal swab PCR,
In the 14 studies with longitudinal data that reported information on the evolution of symptomatic status, nearly three quarters of persons who tested positive but had no symptoms at the time of testing remainedasymptomatic. Current data suggest that infected persons without symptoms—including both presymptomatic and asymptomatic persons—account for more than 40% of all SARS-CoV-2 transmission.
1. Treatment with IV ferric carboxymaltose reduced the risk of heart failure hospitalizations in patients with iron deficiency and acute heart failure with a left ventricular ejection fraction less than 50%. 2. IV ferric carboxymaltose was generally safe but had no significant effect on the risk of cardiovascular death compared to placebo. Evidence Rating Level: 1
U.S. schools operating in-person have experienced low transmission of the Chinese coronavirus, particularly when mitigation strategies such as masking and social distancing are in place, U.S. Centers for Disease Control and Prevention (CDC) Director Rochelle Walensky stressed on Friday, citing new findings by the health agency. Under President Joe Biden, the CDC has expressed support
The key question in 2021 is whether the new strains of coronavirus will be able to eradicate the vaccine-induced immunity. This paper on JAMA by John P Moore and Paul A Offit of Cornell and Pennsylvania Universities has been recently published on JAMA. The protection that vaccines provide against COVID-19 infection is mediated primarily by
Efficacy and safety of corticosteroids in patients with SARS-CoV-2 infection still are debated. Because large randomized clinical trials (RCTs) and a well-conducted meta-analysis on the use of corticosteroids, focused on patients with coronavirus disease (COVID-19) in intensive care units, recently were published, a meta-analysis of RCTs on corticosteroids therapy in patients with different disease severity
An international team of researchers has characterized the effect and molecular mechanisms of an amino acid change in the SARS-CoV-2 Spike protein N439K. Viruses with this mutation are both common and rapidly spreading around the globe. The peer reviewed version of the study appears January 25 in the journal Cell. Investigators found that viruses carrying this
In the United States alone, over 100,000 people are on the organ transplant list. Around 17 of these people will die per day without having received the transplant. It’s clear that organs from human donors will never be adequate for everyone looking for a transplant. Thus, scientists have been researching alternatives, such as using organs made from repurposed stem
Women and children bear substantial morbidity and mortality as a result of armed conflicts. This paper published in The Lancet focuses on the direct (due to violence) and indirect health effects of armed conflict on women and children (including adolescents) worldwide. It was estimate that nearly 36 million children and 16 million women were displaced
The Clalit Research Institute is currently examining the effect of the vaccine against the coronavirus developed by Pfizer. Preliminary data show that 14 days after the injection of the first vaccine, there is a real decrease in the rate of infection in the corona . The study compared the infection data of about 200,000 people aged 60 and over who
As of January 20, 2021, a total of 24,135,690 cases of coronavirus disease 2019 (COVID-19) and 400,306 associated deaths had been reported in the United States (https://covid.cdc.gov/covid-data-tracker/#cases_casesper100klast7days).

Scientists at Children’s Hospital Los Angeles develop newer CAR T therapy that promises to be more effective and less toxic for children with neuroblastoma. Chimeric Antigen Receptor T-cell therapy—CAR T—has revolutionized leukemia treatment. Unfortunately, the therapy has not been effective for treating solid tumors including childhood cancers such as neuroblastoma. Preclinical studies using certain CAR
Following implementation of vaccination, reports of anaphylaxis after the first dose of the Pfizer-BioNTech COVID-19 vaccine emerged.Anaphylaxis is a life-threatening allergic reaction that occurs rarelyafter vaccination, with onset typically within minutes to hours.Notifications and reports of suspected severe allergic reactions and anaphylaxis following vaccination were captured in the Vaccine Adverse Event Reporting System (VAERS), the
Researchers in Cedars-Sinai Medical Center, Los Angeles found that the variant, originated in California, was present in more than half of samples tested last week by researchers in Los Angeles. In late December, scientists in California began searching coronavirus samples for a fast-spreading new variant that had just been identified in Britain. They found it, though in
The increased prevalence of obesity, diabetes and cardiovascular risk factors in people hospitalized with severe COVID-19 illness has engendered considerable interest in the metabolic aspects of SARS-CoV-2-induced pathophysiology. In this paper published in Cell Metabolism are updated concepts informing how metabolic disorders and their comorbidities modify the susceptibility to, natural history and potential treatment of
Virus-specific humoral and cellular immunity act synergistically to protect the host from viral infection. In this paper published on Cell Reports are interrogated the dynamic changes of virological and immunological parameters in 12 patients with symptomatic acute SARS-CoV-2 infection from disease onset to convalescence or death. SARS-CoV-2 viral RNA in the respiratory tract in parallel
Evidence is growing that self-attacking ‘autoantibodies’ could be the key to understanding some of the worst cases of SARS-CoV-2 infection. More than a year after COVID-19 emerged, many mysteries persist about the disease: why do some people get so much sicker than others? Why does lung damage sometimes continue to worsen well after the body
A new study found that antibodies in patients vaccinated against COVID-19 were able to neutralize a version of the new variant. Researchers tested 10 mutations of the B117 variant, which was first identified in the UK. The COVID-19 vaccine developed by BioNTech and Pfizer is likely to protect against the highly infectious variant of the virus, originally found
No definitive treatment for COVID-19 exists although promising results have been reported with remdesivir and glucocorticoids. Short of a truly effective preventive or curative vaccine against SARS-CoV-2, it is becoming increasingly clear that multiple pathophysiologic processes seen with COVID-19 as well as SARS-CoV-2 itself should be targeted. Because alpha-1-antitrypsin (AAT) embraces a panoply of biologic
SARS-CoV-2 501Y.V2, a novel lineage of the coronavirus causing COVID-19, contains multiple mutations within two immunodominant domains of the spike protein. In a paper recently published on https://www.biorxiv.org/content/10.1101/2021.01.18.427166v1.full.pdf it’s shown that this lineage exhibits complete escape from three classes of therapeutically relevant monoclonal antibodies. Furthermore 501Y.V2 shows substantial or complete escape from neutralizing antibodies in
At the heart of each coronavirus is its genome, a twisted strand of nearly 30,000 “letters” of RNA. These genetic instructions force infected human cells to assemble up to 29 kinds of proteins that help the coronavirus multiply and spread. As viruses replicate, small copying errors known as mutations naturally arise in their genomes. A lineage of coronaviruses will
What do we know about the new variant emerging from Brazil? This variant, known as P.1 or VOC202101/02 in the UK, was first detected in travellers from Brazil who arrived in Japan in January 2021. It involves 17 unique amino acid changes, three deletions, four synonymous mutations, and one 4nt insertion. It has several mutations

A pair of new gene therapies promise a potentially lasting cure for sickle cell disease by subtly altering the genetic information in patients’ bone marrow cells, researchers report. Both therapies work by switching on a gene that promotes production of fetal hemoglobin, said Dr. Lewis Hsu, chief medical officer of the Sickle Cell Disease Association
COVID-19 tests that use patients’ saliva to screen for the virus are just as effective as those that use swabs collected from the nose and throat, an analysis published by JAMA Internal Medicine found. Saliva-based tests correctly identified those infected with the new coronavirus 83% of the time, while nose-throat swab tests were 85% accurate, the review of
On December 14, 2020, the United Kingdom reported a SARS-CoV-2 variant of concern (VOC), lineage B.1.1.7, also referred to as VOC 202012/01 or 20I/501Y.V1.* The B.1.1.7 variant is estimated to have emerged in September 2020 and has quickly become the dominant circulating SARS-CoV-2 variant in England (1). B.1.1.7 has been detected in over 30 countries,
The RECOVERY trial was established as a randomised clinical trial to test a range of potential treatments for COVID-19. Since May 2020, the RECOVERY trial has included a randomised comparison of convalescent plasma vs. usual care alone. Convalescent plasma has been widely used as a treatment for COVID-19 but to date there has been no
Despite the significant improvement in survival outcomes of multiple myeloma (MM) over the past decade, it remains an incurable disease. Patients with triple-class refractory MM have limited treatment options and a dismal prognosis. Chimeric antigen receptor (CAR) T-cell therapy targeting B-cell maturation antigen has transformed the treatment armamentarium of relapsed/refractory MM (RRMM), with unprecedented overall
Imbalances in type and volume of bacteria may also be implicated in ‘long COVID’ The variety and volume of bacteria in the gut, known as the microbiome, may influence the severity of COVID-19 as well as the magnitude of the immune system response to the infection, suggests research published online in the journal Gut. Imbalances in
EMA has received an application for conditional marketing authorisation (CMA) for a COVID-19 vaccine developed by AstraZeneca and Oxford University. The assessment of the vaccine, known as COVID-19 Vaccine AstraZeneca, will proceed under an accelerated timeline. An opinion on the marketing authorisation could be issued by 29 January during the meeting of EMA’s scientific committee for human medicines (CHMP), provided
A model developed by CDC researchers estimates that 59% of coronavirus cases in the United States are spread by asymptomatic carriers. Transmissions from individuals who have not yet begun to exhibit signs of infection account for 35% of that total, while transmissions from people who never develop symptoms make up the other 24%. A model
Exosomes are nano-sized extracellular vesicles secreted by all cells. Extensive research over recent years has now shown these vesicles to be important players in intercellular signalling and to have a role in tissue regeneration, immunomodulation and other biological functions. A lipid bilayer protects the exosome cargo of nucleic acids and proteins from degradation and permits
Pregnant women infected with SARS-CoV-2 appear to be at higher risk of developing severe cases of COVID-19 than infected women who are not pregnant. Yet newborns are mostly doing well. Reports indicate that only about 5 percent of babies born to COVID-19-infected mothers are themselves infected, and most newborns who test positive have mild or
Dozens of people being treated for COVID-19 at a Florida hospital last summer became additionally infected with a mysterious, often deadly fungus called Candida auris, a US government study said Friday. The multidrug-resistant yeast was first identified in Japan in 2009 and has been a top priority for the Centers for Disease Control and Prevention
COVID-19 patients admitted to intensive care in the early months of the pandemic were subject to a significantly higher burden of delirium and coma than is typically found in patients with acute respiratory failure. Choice of sedative medications and curbs on family visitation played a role in increasing acute brain dysfunction for these patients. That’s
Clinicians should consider prescribing intravenous tocilizumab following the criteria defined below for patients in intensive care. Intravenous sarilumab could be considered as an alternative (if available).Any provider organisation treating patients with this intervention will be required to assure itself that the internal governance arrangements have been completed before either medicine is prescribed. These arrangements may
Pfizer Inc. and BioNTech SE announced results from an in vitro study conducted by Pfizer and the University of Texas Medical Branch (UTMB) that shows the antibodies from people who have received the Pfizer-BioNTech COVID-19 vaccine effectively neutralize SARS-CoV-2 with a key mutation that is also found in two highly transmissible strains. The results were published
When we speak of variants we refer to differences in the sequence of the genome due to mutations. Strain is a variant in which changes in its biology are demonstrated (antigenicity, transmissibility, virulence,…). For now, let’s talk about variants. The evaluation of the new variants should answer these questions: Has the new variant appeared by
Impact on molecular tests remains low The U.S. Food and Drug Administration is alerting clinical laboratory staff and health care providers that the FDA is monitoring the potential impact of viral mutations, including an emerging variant from the United Kingdom known as the B.1.1.7 variant, on authorized SARS-CoV-2 molecular tests, and that false negative results

The study was published in the journal Nature, and was
Scientists regenerate parts of the skull affected by craniosynostosis, a common birth defect. Using stem cells to regenerate parts of the skull, scientists corrected skull shape and reversed learning and memory deficits in young mice with craniosynostosis, a condition estimated to affect 1 in every 2,500 infants born in the United States, according to the
ApoE4, a strong genetic risk factor for Alzheimer’s disease, has been associated with increased risk for severe COVID-19. However, it is unclear whether ApoE4 alters COVID-19 susceptibility or severity and the role of direct viral infection in brain cells remains obscure. In this paper, published in Cell Stem Cells, the Authors tested the neurotropism of
Therapies to interrupt the progression of early coronavirus disease 2019 (Covid-19) remain elusive. Among them, convalescent plasma administered to hospitalized patients has been unsuccessful, perhaps because antibodies should be administered earlier in the course of illness. In this paper, published on NEJM, the Authors conducted a randomized, double-blind, placebo-controlled trial of convalescent plasma with high
Corticosteroid therapy is now recommended as a treatment in patients with severe COVID-19. But one key question is how to objectively identify severely ill patients who may benefit from such therapy. In a paper just published on Cell Metabolism, 12,862 COVID-19 cases from 21 hospitals in Hubei Province were equally assigned to a training and
The proximal origins of SARS-CoV and MERS-CoV from civets and camels, respectively, are well documented. Few genetic changes in these viruses are required for the interspecies transfers to humans. While precise details and timing of the evolutionary pathways remain to be elucidated, it is also apparent that SARS-CoV-2 emerged from the Sarbecovirus subgenus of the
SARS-CoV-2, the virus that causes COVID-19, has had a major impact on human health globally; infecting a large number of people; causing severe disease and associated long-term health sequelae; resulting in death and excess mortality, especially among older and vulnerable populations; interrupting routine healthcare services; disruptions to travel, trade, education and many other societal functions;
Does it spread more easily? Make people sicker? Mean that treatments and vaccines won’t work? Questions are multiplying as fast as new variants of the coronavirus, especially the one moving through England and now popping up in the U.S. and other countries. Scientists say there is reason for concern and more to learn but that
In an in-depth study of how COVID-19 affects a patient’s brain, National Institutes of Health researchers consistently spotted hallmarks of damage caused by thinning and leaky brain blood vessels in tissue samples from patients who died shortly after contracting the disease. In addition, they saw no signs of SARS-CoV-2 in the tissue samples, suggesting the
The new vaccine has been approved today after meeting the required safety, quality and effectiveness standards. The COVID-19 vaccine developed by Oxford University/AstraZeneca has today been given regulatory approval by the Medicines and Healthcare products Regulatory Agency (MHRA) after meeting required safety, quality and effectiveness standards. Following a rigorous, detailed scientific review by the MHRA’s
Severe coronavirus disease 2019 (COVID-19) is characterized by the intense formation of neutrophil extracellular traps (NETs), leading to the occlusion of microvessels, as shown in pulmonary samples. The occurrence of ST-elevated myocardial infarction (STEMI) is a serious cardiac manifestation of COVID-19; the intrinsic mechanism of coronary thrombosis appears to still be unknown. Objective of the
Children get sick less often than adults due to Covid-19, but children are at risk. This is the key insight from a paper in the Journal of American Medical Association (JAMA), a peer-reviewed medical journal, as the year draws to an end. The paper summarizes the current understanding of how children are affected by Covid-19. So far
Vaccines typically require years of research and testing before reaching the clinic, but in 2020, scientists embarked on a race to produce safe and effective coronavirus vaccines in record time. Researchers are currently testing 64 vaccines in clinical trials on humans, and 19 have reached the final stages of testing. At least 85 preclinical vaccines are under active
The SARS-CoV-2 spike (S) protein is the target of vaccine design efforts to end the COVID-19 pandemic. Despite a low mutation rate, isolates with the D614G substitution in the S protein appeared early during the pandemic, and are now the dominant form worldwide. In this paper are explored spike conformational changes and the effects of
The SARS-CoV-2 pandemic poses an unprecedented public health crisis. Evidence suggests that SARS-CoV-2 infection causes dysregulation of the immune system. However, the unique signature of early immune responses remains elusive. In this paper the transcriptome of rhesus macaques and mice infected with SARS-CoV-2 was characterized. Alarmin S100A8 was robustly induced in SARS-CoV-2 infected animal models
Recently a distinct phylogenetic cluster (named lineage B.1.1.7) was detected within the COG-UK surveillance dataset. This cluster has been growing rapidly over the past 4 weeks and since been observed in other UK locations, indicating further spread. Several aspects of this cluster are noteworthy for epidemiological and biological reasons and we report preliminary findings below.
There’s a growing variety and availability of tests related to SARS-CoV-2. All types of tests can help healthcare providers make more accurate diagnosis, support better management of individual patients and provide better guidance to manage population risk. Active infection is detected with RT-PCR tests detect the presence of SARS-CoV-2 based on its genetic make up (RNA). These tests
Adults 45 years or older were more likely to die from COVID-19 during those months than from chronic lower respiratory disease, transport accidents (eg, motor vehicle fatalities), drug overdoses, suicide, or homicide. In contrast, for individuals younger than age 45 years, other causes of death, such as drug overdoses, suicide, transport accidents, cancer, and homicide
“Thanks to this technology and to the specific fighting capabilities of these cells, extraordinary results have been obtained: The therapy is a new hope for patients who no longer responded to other treatments. The therapy seems to have a long-lasting effect after a single application Unlike many other therapies, which benefit only a small portion
Targeting endothelial cells –cells that comprise the blood vessel wall which regulate oxygen exchange between airways and the bloodstream– may be a novel approach restoring normal lung function to Covid-19 patients with serious lung disease. This hypothesis stems from a study by researchers in the Department of Microbiology and Immunology in the Renaissance School of
There are lots of useful online resources to learn about COVID-19 and some of the clinical studies taking place across the country. What’s been missing is a one-stop online information portal that pulls together the most current information for people of all groups, races, ethnicities, and backgrounds who want to get involved in fighting the
The CLI study is unlikely to meet its primary endpoint by the time of the final analysis Substantial low number of events in the placebo group in the CLI study decreased the statistical power of the study to meet its primary endpoint PLX-PAD was well tolerated, and no safety concerns were raised Company to terminate the CLI study to focus on different therapeutic areas in its pipeline and expects three clinical readouts within the coming calendar year
CALCULATOR GENERATES MORTALITY RISK ESTIMATES FOR INDIVIDUALS AND COMMUNITIES BASED ON SOCIODEMOGRAPHIC INFO AND MEDICAL HISTORY A new online calculator for estimating individual and community-level risk of dying from COVID-19 has been developed by researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers who developed the calculator expect it to be useful to
Potential treatments for Covid-19 have been identified after the discovery of five genes associated with the most severe form of the disease. Genetic evidence is second only to clinical trials as a way to tell which treatments will be effective in a disease. Existing drugs that target the actions of the genes reveal which drugs
During the coronavirus disease 2019 (COVID-19) pandemic, the general public has been advised to wear masks or improvised face coverings to limit transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). However, there has been considerable confusion and disagreement regarding the degree to which masks protect thewearer from airborne particles. To evaluate the fitted filtration
World Health Organization expert groups recommended mortality trials of four repurposed antiviral drugs (remdesivir, hydroxychloroquine, lopinavir and interferon beta-1a) in patients hospitalized with Covid-19. Inpatients with Covid-19 were randomly assigned equally between one of the trial drug regimens that was locally available and open control (up to five options, four active and the local standard
In a 17-4 vote, with one abstention, a panel of advisers to the Food and Drug Administration recommended Thursday that the COVID-19 vaccine being developed by Pfizer and BioNTech be authorized for emergency use during the coronavirus pandemic. The vote in favor of the vaccine was taken to answer the agency’s question: Do the benefits
Previous studies reported on the safety and applicability of mesenchymal stem/stromal cells (MSCs) to ameliorate pulmonary inflammation in acute respiratory distress syndrome (ARDS). Thus, multiple clinical trials assessing the potential of MSCs for COVID-19 treatment are underway. Yet, as SARS-inducing coronaviruses infect stem/progenitor cells, it is unclear whether MSCs could be infected by SARS-CoV-2 upon

The more common manifestation in the COVID-19 era may be HFpEF related primarily to the unmasking of subclinical HFpEF and secondarily to the development of new HFpEF following infection with SARS-CoV-2. Patients with preexisting cardiovascular disease (CVD) who develop coronavirus disease 2019 (COVID-19) have worse outcomes than patients without CVD.Infection with severe acute respiratory syndrome
Fewer than 10 percent of the U.S. adult population formed antibodies against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) during the first wave of the pandemic, according to a study published online Sept. 25 in The Lancet. Shuchi Anand, M.D., from the Stanford University School of Medicine in Palo Alto, California, and colleagues conducted a cross-sectional
In this randomized clinical trial, although limited by early termination, there was no clinical benefit of hydroxychloroquine administered daily for 8 weeks as pre-exposure prophylaxis in hospital-based HCWs exposed to patients with COVID-19. Despite promising early reports and strong in vitro performance, Hydroxychloroquine (HCQ) has become the major therapeutic disappointment of the COVID pandemic. Research
Research in England shows a dangerous relationship between the viruses that cause both diseases; for those in the ICU with co-infection, the risk of death is 6.33 times higher. People infected at the same time by the new coronavirus and the flu virus are twice as likely to die than those infected by Sars-Cov-2 alone . This is the
Two categories of disease are interacting within specific populations—infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and an array of non-communicable diseases (NCDs). These conditions are clustering within social groups according to patterns of inequality deeply embedded in our societies. The aggregation of these diseases on a background of social and economic disparity exacerbates
Early in the pandemic, other clinicians noted that even some patients who didn’t have preexisting heart conditions experienced cardiovascular damage while fighting COVID-19 infections, pointing to a possible causative link. Researchers had found, for example, that 8–12 percent of hospitalized COVID-19 patients had elevated levels of muscle contraction–regulating proteins called troponins—a sign of heart damage—and that these
Currently, no Food and Drug Administration (FDA)-approved therapeutics exist for coronavirus disease 2019 (COVID-19). In this context, the pandemic has put considerable pressure on health care providers to prescribe treatments despite limited information about their safety and efficacy. This pressure has exacerbated the tension between the importance of practicing evidence-based medicine and the urgency of
New findings by scientists at the National Institutes of Health and their collaborators help explain why some people with COVID-19 develop severe disease. The findings also may provide the first molecular explanation for why more men than women die from COVID-19. The researchers found that more than 10% of people who develop severe COVID-19 have
Children were less likely than adults to acquire a COVID-19 infection from an index case, a meta-analysis found. Across 32 contact tracing or population testing studies comparing SARS-CoV-2 prevalence in children and adults, children younger than 14 were less likely to be infected from an index case overall (odds ratio 0.56, 95% CI 0.37-0.85), and
COVID-19 appears to have significant extrapulmonary complications affecting multiple organ systems. Critically ill patients with COVID-19 oftendevelop gastrointestinal complications during their hospital stay, including bowel ischemia, transaminitis, gastrointestinal bleeding, pancreatitis, Ogilvie syndrome, and severe ileus.

Multisystem inflammatory syndrome in children (MIS-C), believed to be linked to COVID-19, damages the heart to such an extent that some children will need lifelong monitoring and interventions, said the senior author of a medical literature review. Case studies also show MIS-C can strike seemingly healthy children without warning three or four weeks after asymptomatic
Young adults with underlying conditions such as morbid obesity, diabetes and hypertension are at the highest risk of being placed on a ventilator or dying from COVID-19, according to a study of 3,000 hospitalized patients aged 18 to 34. The analysis, published Wednesday in the journal JAMA Internal Medicine, focused on patients hospitalized between April and
SARS-CoV-2, the virus that causes COVID-19, is entirely new to infectious disease researchers and other public health scientists. To combat it, scientists have sifted through centuries of literature about how the world coped with past pandemics. A new opinion paper assesses one way in which we might be able to learn from our encounters with
People who are admitted to hospital with Covid-19 can be divided into four distinct groups, according to data from the world’s largest study of patients with the disease. Researchers identified the groups using clinical information and tests carried out upon arrival at hospital to predict the patients’ risk of death – ranging from low to
The COVID-19 pandemic is still raging in India, with over 4.5 million cases, 75.000 deaths and more than 90,000 new cases a day. At present there are few effective therapeutic options, which means that healthcare providers are faced with ongoing challenges in managing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). A new study based
The strong pro-inflammatory response known as cytokine storm is said to play an important role in the pathophysiology of a severe variant of covid-19. But researchers at Radboudumc University (Matthijs Kox et al.) doubt that. In a small-scale study published in JAMA, they argue that many studies look at different cytokines and do not make a
One of the features distinguishing SARS-CoV-2 from its more pathogenic counterpart SARS-CoV is the presence of premature stop codons in its ORF3b gene. In this paper it’s shown that SARS-CoV-2 ORF3b is a potent interferon antagonist, suppressing the induction of type I interferon more efficiently than its SARS-CoV ortholog. Phylogenetic analyses and functional assays reveal

This inoculation, which was performed in a biosafety level 3 facility, had a multiplicity of infection (indicating the ratio of virus particles to targeted airway cells) of 3:1. These cells
Dozens of major hospitals across the U.S. are grappling with whether to ignore a federal decision allowing broader emergency use of blood plasma from recovered COVID patients to treat the disease in favor of dedicating their resources to a gold-standard clinical trial that could help settle the science for good. As many as 45 hospitals
Treating critically ill COVID-19 patients with corticosteroid drugs reduces the risk of death by 20 percent, an analysis of seven international trials found on Wednesday, prompting the World Health Organization to update its advice on treatment. The analysis — which pooled data from separate trials of low dose hydrocortisone, dexamethasone and methylprednisolone — found that steroids improve survival
The rush to immunise populations against Covid-19 could lead to the rollout of a vaccine that is not very effective and risk worsening the pandemic, leading scientists have said. Experts, members of the WHO’s Solidarity Vaccines Trial Expert Group, which is made up of leading scientists around the world who are advising on the establishment
The study has been done in seven Italian Hospitals and published on The Lancet Respiratory Medicine The study confirms the role of microthrombosis in severe Covid-19, but do not explain which is the pathophysiology of the proteolytic cascades activation. For Dr. Fornasari, REGENHEALTHSOLUTIONS Director, “This study very important study shows that unhinibited proteolytic cascades activation
New research suggests that children can shed SARS-CoV-2, the virus that causes COVID-19, even if they never develop symptoms or for long after symptoms have cleared. But many questions remain about the significance of the pediatric population as vectors for this sometimes deadly disease, according to an invited commentary by Children’s National Hospital doctors that accompanies this
Over 1,000 children from Northern Ireland, Scotland, England and Wales, known as ‘COVID Warriors’ have had their antibodies measured in the UK-wide trial called ‘Seroprevalence of SARS-Cov-2 infection in healthy children’. The findings have been published yesterday (Friday 28 August) as a pre-print on the server medRxiv. The study is led by Queen’s University Belfast, in
Study is the basis of a new international clinical trial Early in the COVID-19 pandemic, Mount Sinai researchers were among the first to show that anticoagulation therapy was associated with improved survival among hospitalized COVID-19 patients. But many questions remained—about the size of the potential benefit, and about what dosage of this therapy might be
A new Covid-19 prediction model makes another compelling case for wearing masks and cloth face coverings. If practically everyone in America wears masks while out in public, it could prevent tens of thousands of Covid-19 infections and deaths by the fall, according to researchers at the University of Washington’s Institute for Health Metrics and Evaluation (IHME). “It is hard
Infection in General Population Mirrors Pediatric Prevalence, UCSF Study Shows Source UCSF As schools across the country continue to wrestle with configurations of online and in-classroom learning, a new study from UCSF Benioff Children’s Hospitals shows that public data and a simple equation may be all that is required to estimate the number of infected
Source NIH “Masks save lives” isn’t just sound advice, it’s a scientific fact. Wearing one in public can help to slow the spread of SARS-CoV-2. Wear a mask outside home, doesn’t necessarily protect myself, but protect others. If by chance I’ve been exposed to the virus and am currently incubating it, I wouldn’t want to
The Food and Drug Administration (FDA) authorized emergency use of convalescent plasma and the national Expanded Access Program (EAP) for convalescent plasma led by Mayo Clinic announced its intention to discontinue enrollment. The five-month program served 2,780 hospital and acute care facilities, with nearly 14,000 physicians enrolling 101,000 patients and reports of 71,000 infused so far. Eligible patients who
The research presented early in the course of Corona pandemic found that Covid-19 not as initially suspected a classic viral lung disease. Rather, the whole body is affected . A team from the University Hospital Hamburg-Eppendorf (UKE) has now proven that the new coronavirus SARS-CoV-2 can also multiply in the kidneys . The novel corona virus can also multiply outside of the lungs, for example in the kidneys. Researchers at the University Medical Center
Recent reports that antibodies to SARS-CoV-2 are not maintained in the serum following recovery from the virus have caused alarm. However, the absence of specific antibodies in the serum does not necessarily mean an absence of immune memory. University of Bergen researchers have just published a paper on Nature Reviews Immunology. Immunity after infection with
Source FDA Yesterday 08/23/2020 FDA has issued guidance to provide recommendations to health care providers and investigators on the administration and study of investigational convalescent plasma collected from individuals who have recovered from COVID-19 (COVID-19 convalescent plasma) during the public health emergency. The guidance provides recommendations on the following: pathways for use of investigational COVID-19 convalescent plasma
There is an increased attention to stroke following SARS-CoV-2. The goal of this study was to better depict the short-term risk of stroke and its associated factors among SARS-CoV-2 hospitalized patients. This multicentre, multinational observational study includes hospitalized SARS-CoV-2 patients from North and South America (United States, Canada, and Brazil), Europe (Greece, Italy, Finland, and
Infusing hospitalized Covid-19 patients with blood plasma from people who recovered from the disease appeared to show a benefit in a nationwide study, but the study’s lack of a placebo group left several experts struggling to interpret the data. The study, which enrolled more than 35,000 patients, found that quickly administering so-called convalescent plasma had
A new research study used whole-genome sequencing to analyze the genetic profile of patients with the SARS-CoV-2 virus to gain more insight into how it turns the body’s own immune system against itself. The findings could help researchers develop drugs to target the virus, according to an August 3 report in Nature Medicine. Researchers focused on
A mutant SARS-CoV-2 variant that has appeared in East Asia appears to cause milder infections than the form without this mutation. Overall, there are initial indications that the coronavirus could weaken. As early as January and February 2020, researchers from Singapore identified a SARS-CoV-2 variant in a cluster of Covid-19 patients that had a 382 base
In a new study, published in Nature Medicine, researchers at the Francis Crick Institute, King’s College London and Guy’s and St Thomas’ NHS Foundation Trust, have found a common immune signature in the blood of patients with COVID-19, which could be used to predict how severely ill a patient will become, thereby aiding patient management. The team analysed blood samples
Neurological complications have emerged as a significant cause of morbidity and mortality in the ongoing COVID-19 pandemic. Beside respiratory insufficiency, many hospitalized patients exhibit neurological manifestations, ranging from headache and loss of smell, to confusion and disabling strokes. COVID-19 is also anticipated to take a toll on the nervous system in the long term. In
The release of massive amounts of proteins called cytokines can lead to some of the most severe symptoms of COVID-19. When large numbers of immune cells release cytokines, this increases inflammation and creates a feedback loop in which more immune cells are activated and this is sometimes called a cytokine storm. An August 19 study
New lab-based studies show that two existing drugs, including one developed by a researcher at Harvard Medical School and Boston Children’s Hospital, inhibit SARS-CoV-2 — the virus that causes COVID-19 — from infecting human cells in a dish. Both drugs, vacuolin-1 and apilimod, originally developed years ago, target a large enzyme called PIKfyve kinase. Before
The virus causing the COVID-19 pandemic, SARS-CoV-2, presents at least six strains. Despite its mutations, the virus shows little variability, and this is good news for the researchers working on a viable vaccine. These are the results of the most extensive study ever carried out on SARS-CoV-2 sequencing. Researchers at the University of Bologna drew
A new study is challenging the idea that younger children are somehow less susceptible to SARS-CoV-2 infection. Children under the age of five have been found to carry just as much, if not more, coronavirus in their noses and throats than older kids or adults. The results, published Thursday (July 30) in JAMA Pediatrics, tested 145
