People discharged from hospital after Covid-19 appear to have increased risks of diseases across multiple organs and nearly a third are readmitted to hospital in the following months, according to a new study co-led by researchers at University College London. The study, published in The BMJ, looked at nearly 50,000 people who were discharged from hospital by August last year and compared them to…
A University of Manchester team has applied new techniques to detect and track the transmission of Covid-19 in hospital. The proof of concept system combines the movement and interaction of staff and patients with genomic sequencing of the virus, helping to signpost how best to improve patient pathways, staff movement and reduce risk. They identified hotspots within hospitals where patients and…
Recovery duration, co-morbidities, mortality, risk groups: A large UK study reports in detail on 'Long Covid'. We spoke with two of the study's co-investigators about why so many patients are still affected after a coronavirus infection.
Skin swab samples analysed using mass spectrometry could be used to detect Covid-19 in patients, according to research conducted at the University of Surrey in the UK. Current Covid-19 testing is via a polymerase chain reaction (PCR) test, which involves taking a swab of the back of the throat and inside the nose, but the team from Surrey - working with Frimley NHS Trust and the Universities of…
The first known study to measure SARS-CoV-2 viral load in a variety of organs and tissues may aid our understanding of how Covid-19 develops following infection.
In the largest study of its kind to date, researchers at Massachusetts General Hospital, Brigham and Women’s Hospital and the Ragon Institute of MGH, MIT and Harvard have found the new mRNA Covid-19 vaccines to be highly effective in producing antibodies against the SARS-CoV-2 virus in pregnant and lactating women. They also demonstrated the vaccines confer protective immunity to newborns…
Researchers from Charité – Universitätsmedizin Berlin and the Francis Crick Institute have developed a mass spectrometry-based technique capable of measuring samples containing thousands of proteins within just a few minutes. It is faster and cheaper than a conventional blood count. To demonstrate the technique’s potential, the researchers used blood plasma collected from Covid-19 patients.…
More than four in five (86%) people who were unsure or said no to a Covid-19 vaccine in December 2020 would now take one, or have already been vaccinated, finds the latest research by the Virus Watch study conducted by University College London (UCL).
The Institute for Research in Biomedicine (IRB) in Switzerland developed a second-generation ‘double antibody’ that protects from SARS-CoV-2, the virus causing Covid-19, and all its tested variants. It also prevents the virus from mutating to resist the therapy. Antibody-based immunotherapy was already shown to be effective against Covid-19 but faces two main obstacles: it needs to work…
Scientists from Singapore found that antibodies against SARS-CoV-2 wane at different rates, lasting for mere days in some individuals, while remaining present in others for decades. The study, published in The Lancet Microbe, shows that the severity of the infection could be a deciding factor in having longer-lasting antibodies. Individuals with low levels of neutralising antibodies may still be…
Researchers are developing a COVID-19 vaccine that could provide protection against both existing and future strains of the COVID-19 virus, and other coronaviruses, and cost about $1 a dose has shown promising results in early animal testing.
Researchers at University of Toronto have developed a new test to accurately detect coronavirus antibodies in a drop of blood in less than an hour.
Thermo Fisher Scientific and Artificial have announced a strategic technology collaboration to develop an integrated and comprehensive software automation platform for Thermo Fisher’s standardized COVID-19 Testing Platform. The integration will result in increased testing throughput and support global healthcare initiatives.
Researchers from Cleveland Clinic’s Florida Research and Innovation Center (FRIC) have identified a potential new target for anti-COVID-19 therapies.
Researchers investigated whether the vaccine recipients developing unusual thrombotic events and thrombocytopenia could have a prothrombotic disorder caused by platelet-activating antibodies directed against a platelet protein, as a similar mechanism is known to be caused by heparin and sometimes other environmental triggers.
A study conducted by Columbia University Mailman School of Public Health researchers reports a high global prevalence of both depression and anxiety during the Covid-19 pandemic. It also shows how the implementation of mitigation strategies including public transportation and school closures, and stay-at-home orders impacted such disorders. Results are published in Psychological Medicine.
Even as vaccines are becoming more readily available, protecting against the asymptomatic and pre-symptomatic spread of the virus (SARS-CoV-2) that causes Covid-19 is key to ending the pandemic, say two infectious disease experts at the Georgetown University Medical Center. In their Perspective, “SARS-CoV-2 Transmission Without Symptoms,” published in the journal Science, they make the case…
Moderna and IBM announced their intentions to explore technologies, including artificial intelligence, blockchain and hybrid cloud, that could help support smarter Covid-19 vaccine management. Central to the effort will be a pilot of open, standardized, technology-enabled vaccine distribution approaches aimed to improve supply chain visibility and foster near real-time tracking of vaccine…
A study published by The BMJ sheds light on the risk of infection with SARS-CoV-2 and covid-19 outcomes among adults living with and without children during the first two waves of the UK pandemic. It finds no evidence of any increased risk in wave 1 (Feb to Aug 2020). Small increased risks of infection and hospital admission were seen in wave 2 (Sept to Dec 2020), but this did not translate into…
Rapid tests, PCR tests, self-tests… there are many test options to determine contamination with Covid-19. In most this is done by inserting a cotton swab deep into the nose and/or throat to extract some mucus – unpleasant for adults and often a drama for children. Towards the end of 2020, a new system emerged to rule out a Covid-19 contamination. The electronic SpiroNose performs a…
In what is believed to be the first published study of Covid-19 vaccine effectiveness in long-term care facilities such as nursing homes, a research team co-led by the Yale School of Public Health found a widely used vaccine is highly successful in preventing infections. Residents of such facilities, particularly those in skilled nursing facilities (SNFs), have experienced disproportionately high…
Systematic review finds that machine learning models for detecting and diagnosing Covid-19 from medical images have major flaws and biases, making them unsuitable for use in patients. However, researchers have suggested ways to remedy the problem. Researchers have found that out of the more than 300 Covid-19 machine learning models described in scientific papers in 2020, none of them is suitable…
The results of a large-scale study indicate that the introduction of an AI-powered solution by healthcare software company Radlogics into radiology workflow to analyze Chest-CT scans during the Covid-19 pandemic reduced report turnaround time by an average of 30 percent, which is equivalent to 7 minutes per case.
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population’s response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors…
The highly infectious variant of Covid-19 discovered in Kent, which swept across the UK last year before spreading worldwide, is between 30 and 100 per cent more deadly than previous strains, new analysis has shown. A pivotal study, by epidemiologists from the Universities of Exeter and Bristol, has shown that the SARS-CoV-2 variant, B.1.1.7, is associated with a significantly higher mortality…
