During a pandemic, the demands for laboratory testing challenge routines in an efficiently run clinical laboratory. Gold standard procedures may need modification, or to be discarded, and the more nimble, resilient and receptive a lab is to change, the better off it could be. Senior managers at ARUP Laboratories in Salt Lake City, Utah, a large clinical reference laboratory that offers over 3,000…
Cardiac surgery across Europe is being set back as a result of the ongoing coronavirus. Operations are being postponed, treatment delayed, and critical care staff have been redeployed to cope with the impact of the Covid-19 epidemic on health services. However, gaining a clear picture of the Europe-wide situation, and the long-term effects coronavirus will have on heart surgery, is a challenge…
When airborne pollen levels are higher, increased SARS-CoV-2 infection rates can be observed. These results were determined by a large-scale study conducted by an international team headed by researchers at the Technical University of Munich (TUM) and the Helmholtz Zentrum München. Members of high-risk groups could protect themselves by watching pollen forecasts and wearing dust filter masks.
In order to monitor and contain the spread of SARS-CoV-2 it is necessary to test large numbers of people on a regular basis in decentralized settings. Researchers of the Max Planck Institute for Evolutionary Anthropology and the Hospital St. Georg in Leipzig, Germany, have developed improved protocols for the detection of SARS-CoV-2. The method can detect a positive sample in a pool with 25…
Digital Covid-19 ‘symptom checkers’ may stop some patients from getting prompt treatment for serious illness, suggests an international case simulation study. Both the US and UK symptom checkers consistently failed to identify the symptoms of severe Covid-19, bacterial pneumonia, and sepsis, frequently advising these cases to stay home, the findings indicate. The availability and use of…
A global group of researchers is calling for better integration of viral genetics, bioinformatics, and public health to enable better pandemic response now and better pandemic preparedness in the future. In a comment piece in the journal Nature, an international collaboration of specialists in viral and genetic analysis, led by Swiss scientists Dr. Emma Hodcroft at the University of Bern and…
A research team of pharmacists at the University of Bonn has discovered two families of active substances that can block the replication of the SARS-CoV-2 coronavirus. The drug candidates are able to switch off the the key enzyme of the virus, the so-called main protease. The study is based on laboratory experiments. Extensive clinical trials are still required for their further development as…
The impact of Covid-19 has been devastating; countless lives lost, millions of infections worldwide, health systems overwhelmed and economies rapidly shrinking. Screening, such as for breast or cervical cancer, is an area particularly affected, with numerous appointments delayed.
With public health issues continuing to make daily mainstream news headlines across the world, it is clear how much change the healthcare environment is going through. Not only are there existing pressures on resources, space, staff, certain procedures, and budgets, but there are brand new ones resulting from the ongoing global COVID-19 pandemic. This has led to an even greater need for…
Due to the coronavirus, hospitals and medical staff developed new work practices involving, in acute settings, social distancing, rigid use of personal protective equipment (PPE), handwashing, and disinfection of equipment every day. Additionally, portable, highly-mobile and versatile equipment came to the fore in point-of-care (POC) – particularly when wards and operating theatres are spread…
Computer modelling to forecast Covid-19 mortality contains significant uncertainty in its predictions, according to an international study led by researchers at University College London (UCL) and Centrum Wiskunde & Informatica (CWI) in the Netherlands. Their article ‘The Impact of Uncertainty on Predictions of the CovidSim Epidemiological Code’ was published in Nature Computational…
The European Commission has launched a contingency plan to meet the challenge of the various mutations of the coronavirus. Karolinska Institutet and Karolinska University Hospital are contributing to a new network for the evaluation and testing of new vaccines. The network is called "Vaccelerate" and it will contribute both to the evaluation of ongoing and future vaccinations, as well…
Scientists have developed peptides that fit snugly into a groove on the SARS-CoV-2 Spike protein that it would normally use to access a host cell. These protein fragments effectively trick the virus into “shaking hands” with a replica rather than with the actual protein on a cell’s surface that lets the virus in. revious research has determined that the novel coronavirus binds to a receptor…
For many women, swollen lymph nodes are a red flag pointing to breast cancer – but may also be a normal immune reaction to a Covid-19 vaccination. In this Q&A, breast imaging experts address the most important facts on the topic.
Covid-19 vaccine passports could be created, but significant challenges need to be overcome first, according to a report from a panel led by Oxford Professors Melinda Mills and Chris Dye, which outlines a dozen issues which must be addressed before passports can be introduced. The report is published by the SET-C (Science in Emergencies Tasking: Covid-19) group at the Royal Society and it…
Researchers have called on European policymakers to make adequate resources available to tackle pancreatic cancer, a disease that is almost invariably fatal and where little progress has been made over the past 40 years. In the latest predictions for cancer deaths in the EU and UK for 2021, published in the cancer journal Annals of Oncology, researchers led by Carlo La Vecchia (MD), a professor…

Apheresis, a procedure that separates and removes particular blood constituents, shows promise for Covid-19 cases: the first patient successfully underwent so-called CRP apheresis, which can prevent potentially fatal consequences of the infection.
Preventing air contamination in healthcare facilities is crucial to minimise the airborne spread of Covid-19 and its new strains. Universal masking, rigorous use of and safe disposal of PPE, plus building ventilation are vital. Twenty-four studies reporting hospital SARS-CoV-2 air contamination are summarised in a meta-analysis by a multi-institutional team of French researchers. These show that,…
Researchers at ZHAW Zurich University of Applied Sciences are working with the Swiss company Osmotex AG to develop a self-disinfecting mask that inactivates viruses at the push of a button. The prototype of this mask made of electrochemical textiles shows an antiviral effect of over 99 percent. Further applications such as sterilizable seat covers are being examined.
Around 50% of patients who have been hospitalised with severe Covid-19 and who show raised levels of a protein called troponin have damage to their hearts. The injury was detected by magnetic resonance imaging (MRI) scans at least a month after discharge, according to new findings published in the European Heart Journal. Damage includes inflammation of the heart muscle (myocarditis), scarring or…
The impact of Covid-19 in Africa has been vastly underestimated, warn researchers in a new study. Outside of South Africa, this is the first study to provide systematic surveillance data capturing the impact of Covid-19 in Africa. Their findings are based on polymerase chain reaction (PCR) test results for 364 deceased people of all ages at the University Teaching Hospital morgue in Lusaka,…
To date, testing for SARS-CoV-2 infection mostly has relied on RT-PCR performed on a nasopharyngeal specimen. This testing method is very unpleasant for a patient: the professional tester has to tilt the patient’s head back slightly about 45°-70° to straighten the passage from the front of the nose, insert the swab through the nostril parallel to the palate, and the swab should reach a depth…
A team of researchers studying the effectiveness of different types of face masks has found that in order to provide the best protection against Covid-19, the fit of a mask is as important, or more important, than the material it is made of. The researchers, from the University of Cambridge, carried out a series of different fit tests, and found that when a high-performance mask – such as an…
