01/22/2021 09:02 GMT — Antibody drug may protect nursing home residents

According to a recent study, bamlanivimab, a monoclonal antibody drug manufactured by Eli Lilly and Co., helps prevent COVID-19 in nursing homes. The study involved 299 residents and 666 members of staff. For the residents, bamlanivimab reduced the risk of COVID-19 by 80% during a SARS-CoV-2 outbreak.

However, when the researchers analyzed data from the residents and staff together, they found that the drug reduced the risk of developing COVID-19 symptoms by 57%. Compared with a placebo, bamlanivimab was also associated with a lower risk of COVID-19 mortality and lower viral loads.

The results are encouraging, but as vaccine rollouts focus on older adults, the need for drugs of this type will be reduced. By the time the FDA provide a new emergency use authorization, relatively few nursing home residents and staff should be left unvaccinated.

01/22/2021 08:53 GMT — How some people in US are receiving surprise doses of COVID-19 vaccine

If COVID-19 vaccines thaw or the seal has been punctured, they will perish without use. If shots remain at the end of the shift, healthcare workers will sometimes offer them to people who happen to be near the clinic at closing time.

However, officials believe that as the rollout continues to ramp up and more people become eligible for the shot, fewer and fewer of these leftover doses will be available.

01/20/2021 10:09 GMT — SARS-CoV-2 variant B.1.1.7 detected in 60 countries

According to new data from the World Health Organisation (WHO), the B.1.1.7 variant that scientists in the United Kingdom first reported at the end of 2020 is now present in 60 countries across the globe. Last week, this number stood at 50 countries.

Data from the U.K. suggest that B.1.1.7 is able to spread more easily from person to person. 

The WHO also state that 23 countries have reported cases of infection with a variant that they refer to as 501Y.V2, which was first identified in South Africa. A further set of variants have emerged in Brazil. At the moment, it is not clear whether these variants can spread more easily between people, and the WHO call for more research.

01/20/2021 08:58 GMT — Has the pandemic shifted traditional gender roles in child care?

A recent study investigated how the pandemic has influenced traditional gender roles in child care. The researchers found that child care responsibilities tended to fall to women during the initial wave of the COVID-19 pandemic in the United States. The findings appear in theJournal of Applied Psychology.

Overall, the researchers found that couples working alternating days generally had the best outcomes, with both husbands and wives in this category experiencing the most sleep and the lowest psychological distress. The scientists compared this with couples trying to work in ‘mini-shifts’ or having one parent attempting to do all the child care.

01/19/2021 09:13 GMT — Almost 1 in 3 people treated for COVID-19 in hospitals readmitted after discharge

A recent study tracked 47,780 COVID-19 patients for almost 5 months following hospital discharge. They compared the outcomes of this group with those of matched individuals who had been admitted for reasons unrelated to COVID-19. The people who had received hospital treatment for COVID-19 were 3.5 times more likely to be readmitted.

The group treated for COVID-19 were also 7.7 times more likely to die than those treated for other reasons. The results of the study appear on the preprint server MedRxiv. Older adults and people who were not white had the greatest risk of readmission and death.

The authors conclude: “Individuals discharged from hospital following COVID-19 face elevated rates of multiorgan dysfunction, compared with background levels, and the increase in risk is neither confined to the elderly nor uniform across ethnicities.”

01/18/2021 08:58 GMT — Most hospitalized COVID-19 patients still have symptoms after 6 months

A recent study showed that more than three-quarters of a cohort of COVID-19 patients still had at least one symptom 6 months after being discharged from the hospital. Dubbed “long COVID,” common symptoms include fatigue, coughing, muscle aches, chest pain, heart palpitations, and rashes.

The results appear in the journal The Lancet. Corresponding author Prof. Bin Cao explains that “because COVID-19 is such a new disease, we are only beginning to understand some of its long-term effects on patients’ health.” He continues:

“Our analysis indicates that most patients continue to live with at least some of the effects of the virus after leaving hospital and highlights a need for postdischarge care, particularly for those who experience severe infections.”

01/15/2021 12:02 GMT — Brazilian variant detected in UK

According to scientists, a new variant they believe to have first appeared in Brazil is already in the United Kingdom. Although the variant is distinct from those first spotted in the U.K. and South Africa, it shares certain mutations.

“The Brazilian variant has three key mutations in the spike receptor binding domain (RBD) that largely mirror some of the mutations we are worried about it in the South African variant, hence the concern,” explains Prof. Ravi Gupta, a professor of microbiology at the University of Cambridge in the U.K.

“The SARS-CoV-2 RBD is one of the main targets for our immune defences and also the region targeted by vaccines and changes within this region are therefore worrisome. Vaccines are still likely to be effective as a control measure if coverage rates are high and transmission is limited as far as possible.”

01/15/2021 09:04 GMT — Acute brain dysfunction in ICU patients

A recent study finds that in COVID-19 patients admitted to the intensive care unit (ICU), episodes of brain dysfunction are more common and prolonged than those normally associated with severe respiratory failure. The study appears in The Lancet Respiratory Medicine.

Read more about the study here.


01/15/2021 09:00 GMT — COVID-19: Gut bacteria may influence severity

The authors of a recent study conclude that an individual’s gut microbiome might affect how their body responds to a SARS-CoV-2 infection. More specifically, gut bacteria might influence both the short- and long-term effects of the infection. The results appear in the journal Gut.

Overall, the authors conclude: “Associations between gut microbiota composition, levels of cytokines, and inflammatory markers in patients with COVID-19 suggest that the gut microbiome is involved in the magnitude of COVID-19 severity, possibly via modulating host immune responses.”

The scientists also believe that gut bacteria could play a role in the development of long COVID.

01/13/2021 09:02 GMT — Large-scale study to test interferon beta

Researchers are still working hard to identify and trial drugs that can reduce the severity of COVID-19. One such drug is interferon beta. Scientists in the United Kingdom are embarking on a large-scale study to find out if it can prevent severe COVID-19 symptoms from emerging.

The experimental treatment is an inhaled version of interferon beta, which biotech company Synairgen developed at Southampton University Hospital in the U.K.

Interferon beta is one of the first cytokines to be released during an infection. The protein is the primary driver of the immune response in the lung. SARS-CoV-2 suppresses the release of interferon beta, and the researchers believe that by inhaling the cytokine into the lungs, it will produce a stronger immune response against the virus. 

Last year, a smaller study involving 101 people produced encouraging results.

As the authors concluded, “Patients who received [interferon beta] had greater odds of improvement and recovered more rapidly from SARS-CoV-2 infection than patients who received placebo, providing a strong rationale for further trials.”

The scientists say that they should be able to complete the study by the summer.

01/12/2021 12:35 GMT — Russia to conduct clinical trial for “Sputnik-Light” vaccine

On Monday, Russian authorities declared that, in order to ensure COVID-19 vaccine doses reach enough people, they will test out a one-dose regimen of Sputnik V.

Sputnik V is a COVID-19 vaccine developed by the Gamaleya Research Institute of Epidemiology and Microbiology in Moscow, which was first approved for provisional use in Russia last fall.

The experimental one-dose regimen is dubbed “Sputnik-Light,” and researchers are set to test it in 150 volunteers.

In the meantime, Russia will continue to roll out the two-dose Sputnik V vaccination regimen.

Russian officials have hinted that if the trial of Sputnik-Light is successful, they may make the modified vaccine available for export.

According to Kirill Dmitriev, head of the Russian Direct Investment Fund, which funds the new trial, “‘Sputnik-Light’ can serve as an effective temporary solution for many countries, which are experiencing a peak of coronavirus infection.”

01/12/2021 10:45 GMT — Immunity against SARS-CoV-2 may last at least 8 months

In a new study published in Science, researchers found that immune responses that can fight off SARS-CoV-2 have persisted for more than 8 months after people recovered from COVID-19.

The team from La Jolla Institute in California, led by Prof. Alessandro Sette and Prof. Shane Crotty, analyzed 254 blood samples from 188 individuals who recovered from COVID-19. Of these, 43 samples were taken at least 6 months after the infection with the virus.

The researchers found antibodies, T cells, and memory B cells specific to SARS-CoV-2 to varying degrees, suggesting immunity to severe COVID-19 in most study participants. However, there was variation, and some of the volunteers did not have significant levels of immunity. 

This may be why some people can develop COVID-19 more than once.

01/12/2021 10:11 GMT — Gorillas in San Diego Zoo have COVID-19

After tigers, lions, cats, dogs, and mink, gorillas are the latest animals to contract SARS-CoV-2 outside of lab studies. A press release from the San Diego Zoo, in California, suggests that the virus likely passed to the gorillas from a staff member with an asymptomatic SARS-CoV-2 infection.

After two members of the gorilla troop at the zoo started coughing last week, testing of fecal samples confirmed the presence of SARS-CoV-2. 

“Aside from some congestion and coughing, the gorillas are doing well,” Lisa Peterson, the executive director of the San Diego Zoo Safari Park, said. “The troop remains quarantined together and are eating and drinking. We are hopeful for a full recovery.”

01/11/2021 17:52 GMT — Is there a link between COVID-19 and long-term neurological problems?

Researchers studying the effects of past viral illnesses, including the 1918 flu, on cognitive function suggest that COVID-19 may have long-lasting effects on the brain. However, more research is necessary to draw any conclusions.

Writing in the journal Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association, Dr. Gabriel A. de Erausquin from the University of Texas Health Science Center at San Antonio and collaborators share their perspective on what data from past viral infections may mean for people who recover from COVID-19.

The scientists suggest a link between a person’s risk for neurological disorders, such as Alzheimer’s disease, Parkinson’s disease, and mental health problems, and infection with respiratory viruses. Among the viruses, they cite H1N1, which caused the 1918 flu pandemic, and the SARS-CoV virus, which caused the 2003 SARS epidemic.

Like the new coronavirus, these respiratory viruses are able to infect cells in the brain. The scientists suggest that even people who have had an asymptomatic SARS-CoV-2 infection may be at increased risk of lasting effects on the brain.

Scientists will need to run longer-term studies to see whether they can confirm this theory.

01/07/2021 08:33 GMT — Study finds new evidence of SARS-CoV-2 damaging brain blood vessels

In a recent study, scientists did not find SARS-CoV-2 in the brains of people with the infection. However, in the post-mortem brains of patients who tested positive for COVID-19, they found blood vessel damage caused by inflammation. The results appear in the New England Journal of Medicine.

“We were completely surprised. Originally, we expected to see damage that is caused by a lack of oxygen,” says senior author Dr. Avindra Nath. “Instead, we saw multifocal areas of damage that is usually associated with strokes and neuroinflammatory diseases.”

Dr. Nath plans to continue investigating: “In the future, we plan to study how COVID-19 harms the brain’s blood vessels and whether that produces some of the short- and long-term symptoms we see in patients.”

01/05/2021 10:10 GMT — UK begins third lockdown

Yesterday evening, the United Kingdom’s prime minister, Boris Johnson, announced the U.K.’s third lockdown. Although the U.K. government decided to let pupils return to school on Monday, they reversed the decision that evening. Learning will move online, while people should work from home where possible.

Johnson said the decision is due to the rise of a new variant of SARS-CoV-2, first identified in the U.K. This variant may be more transmissible, although it does not appear to increase the risk of worse disease.

For many experts, this move is unsurprising and arrived too late. Dr. Julian W Tang, honorary associate professor and clinical virologist at the University of Leicester, says:

“We sort of predicted the likely need for this post-Xmas and New Year lockdown because we knew that many people would still try to meet up over the festive season — and we cannot really blame the new variant virus for all of this.”

He continues, “Yet this brief freedom will have long-term costs for business and education — and people’s health, both COVID-19 and non-COVID-19-related.”

In his televised statement, Johnson said, “The weeks ahead will be the hardest yet, but I really do believe that we are entering the last phase of the struggle, because with every jab that goes into our arms, we are tilting the odds against [COVID-19] and in favor of the British people.”

Talking about the latest U-turn, Dr. Catherine Carroll-Meehan, Head of School of Education and Sociology, University of Portsmouth, says, “Closing schools is the right decision. What families, children, and schools need is some certainty. It is a shame that the government do not take decisions in a more certain and timely manner.”

The new lockdown will continue until mid-February.

12/23/2020 11:26 GMT — Taiwan responds to first case of community transmission since April

On Tuesday, Taiwan saw its first domestic case of COVID-19. President Tsai Ing-wen called for calm, asking people to follow the health authorities’ increased physical distancing measures. 

Taiwanese authorities have been quick to trace how the SARS-CoV-2 virus reemerged in the country. An airline pilot who had flown between the United States and Taiwan has drawn criticism for not disclosing his symptoms or movements to Taiwanese authorities. He subsequently received a positive test result for COVID-19.

A close contact of his then received a COVID-19 diagnosis, making this the first case of domestic community transmission since April 12

So far, 170 people identified through contact tracing have had a negative COVID-19 test result, with three people still awaiting their results. 

Taiwan’s authorities introduced strict containment measures in response to the emergence of SARS-CoV-2 earlier this year. So far, the country has seen seven deaths and fewer than 800 cases of COVID-19.

12/21/2020 09:31 GMT — Transport ties to UK severed

Scientists in the United Kingdom have identified a new, more infectious variant of SARS-CoV-2. In response, the U.K.’s Prime Minister Boris Johnson outlined new restrictions on Saturday. Consequently, a number of countries have restricted travel to and from the U.K.

So far, France, Germany, Italy, the Netherlands, Austria, Switzerland, Ireland, Belgium, Israel, and Canada have shut down travel ties. 

According to experts, the SARS-CoV-2 variant does not cause more severe disease and should not interfere with vaccines. However, it appears to spread more easily. 

As the U.K. prepares to leave the European Union in the next few days, the new travel restrictions will add to the already growing chaos.

12/18/2020 09:09 GMT — NICE publish guidelines on vitamin D and COVID-19

Yesterday, the National Institute for Health and Care Excellence (NICE) released a review of recent studies on vitamin D and COVID-19. Overall, they conclude that there is “not enough evidence to support taking vitamin D solely to prevent or treat COVID-19.”

The review was conducted in collaboration with Public Health England and the Scientific Advisory Committee on Nutrition.

The experts reviewed data from both observational studies and randomized controlled trials. They conclude that “It was not possible to determine a direct relationship between vitamin D and COVID-19 based on the available evidence.”

However, because the primary source of vitamin D is sunlight, they advise taking the vitamin during the autumn and winter.

The report also recommends that researchers continue investigating the relationship between COVID-19 and vitamin D in high-quality randomized controlled trials. NICE will continue to review research as it is conducted.

Dr. Alison Tedstone, the chief nutritionist at Public Health England, advises that “everyone, particularly the elderly, those who don’t get outside, and those with dark skin, takes a vitamin D supplement containing 10 micrograms [400 international units] every day.”

12/16/2020 09:09 GMT — BMJ editors question UK lockdown easing for Christmas

In a rare move, the editors of BMJ have penned a joint article. They criticize the government of the United Kingdom’s decision to ease COVID-19 measures around the Christmas period. The authors are concerned that the move will overwhelm the National Health Service (NHS).

In the article, which is only the second joint editorial in 100 years of the journal’s existence, the authors explain that “The planned relaxation of restrictions over Christmas will boost [case] numbers further as the NHS also struggles with the additional demands of winter.”

They worry that the U.K. public “will see the lifting of restrictions over Christmas as permission to drop their guard.” Beyond the impact on the public, the editors are concerned about NHS staff; they write:

“Of particular concern is the effect on staff, many of whom have already worked through the hardest 9 months of their professional lives. Levels of burnout and sickness absence are likely to exceed those already experienced.”

12/15/2020 10:18 GMT — New SARS-CoV-2 variant identified in England

Yesterday, the United Kingdom’s health secretary, Matt Hancock, announced that scientists had identified a new variant of SARS-CoV-2 in England. He explained that it was particularly prevalent in the South, which had recently experienced a sharp rise in cases.

Local authorities have recorded at least 60 COVID-19 cases that involve the new variant, Hancock reported, adding that there was “nothing to suggest” that the variant caused more severe disease or could limit the effects of vaccines.

During a press conference, Chief Medical Officer for England Chris Whitty explained: “There are many variants. It just happens that this one has quite a few more mutations than some of the other variants, so that’s the reason why we’ve taken it particularly seriously.”

He continued, “But there’s nothing to suggest that the symptoms are different, that the testing is different, or that the clinical outcome is different for this variant.”

In an interview with the BBC, Prof. Alan McNally, an expert in microbial genomics at the University of Birmingham, said:

“Let’s not be hysterical. It doesn’t mean it’s more transmissible or more infectious or dangerous. It is something to keep an eye on. Huge efforts are ongoing at characterizing the variant and understanding its emergence. It is important to keep a calm and rational perspective on the strain, as this is normal virus evolution and we expect new variants to come and go and emerge over time.”

Dr. Zania Stamataki, a viral immunologist at the same institution, provided added insight: “The emergence of different coronavirus strains a year after SARS-CoV-2 first jumped to humans is neither cause for panic nor unexpected. […] This virus doesn’t mutate as fast as influenza and, although we need to keep it under surveillance, it will not be a major undertaking to update the new vaccines when necessary in the future.”

12/11/2020 09:31 GMT — Study hints that supplements may reduce COVID-19 risk in females

A recent study found small but significant decreases in the risk of SARS-CoV-2 infection among females who took multivitamins, vitamin D, omega-3 fatty acids, or probiotics. The study has not yet been through the peer review process and appears on the preprint server MedRxiv.

Although the results seem hopeful, Naveed Sattar, a professor of metabolic medicine at the University of Glasgow, in the United Kingdom, who was not involved in the research, adds some perspective:

“These are interesting results, but due to the way the study has been conducted, these data absolutely cannot tell us that taking such supplements ‘protects’ against infection [resulting in] COVID-19.”

The scientists were surprised that the effect was only significant in females. They theorize that this might be because females have more robust immune systems. Alternately, they might be more likely to wear masks or wash their hands than males.

Prof. Seif Shaheen, from Queen Mary University of London, adds further context: “A major concern is that these findings may be confounded by socioeconomic status, given that individuals of higher status are more likely to take supplements and are also less likely to become infected with SARS-CoV-2.”

11/27/2020 11:20 GMT — Antibleeding drug may effectively treat COVID-19

Researchers at Goethe University in Frankfurt, Germany, led a new study showing that the antibleeding drug aprotinin (Trasylol) can stop the new coronavirus from entering healthy host cells. 

The scientists conducted experiments in various types of human cell, using different concentrations of the drug, and in three different strains of the virus. 

As the researchers point out, what is significant is that the drug was effective at a dose that people can realistically take — i.e., a therapeutic dose.

Senior study author Prof. Jindrich Cinatl, from the Institute for Medical Virology at University Hospital Frankfurt, says, “Our findings show that aprotinin is effective against SARS-CoV-2 in concentrations that can be achieved in patients.”

“In aprotinin, we have a drug candidate for the treatment of COVID-19 that is already approved for other indications and could readily be tested in patients.”

11/23/2020 09:52 GMT — AstraZeneca’s ‘Oxford’ vaccine 70% effective

According to a press release, the experimental COVID-19 vaccine developed by Oxford University and AstraZeneca prevents 70.4% of people from developing COVID-19. Although this is lower than the Moderna and Pfizer vaccines, using a different dosing regimen might increase the figure to 90%.

The recent announcement is based on data from 24,000 participants in the United Kingdom, Brazil, and South Africa. Importantly, the Oxford vaccine is cheaper to produce and easier to store and transport than the Moderna and Pfizer offerings.

The trial involved two dosing regimens. One consisted of two full doses, which provided 62% protection. The other involved one half dose followed by one full dose, which provided 90% protection. Prof. Andrew Pollard, the director of the Oxford Vaccine Group and the chief investigator of the Oxford Vaccine Trial, explains:

“These findings show that we have an effective vaccine that will save many lives. Excitingly, we’ve found that one of our dosing regimens may be around 90% effective, and if this dosing [regimen] is used, more people could be vaccinated with planned vaccine supply.”

Dr. Stephen Griffin, an associate professor in the School of Medicine at the University of Leeds, U.K., says:

“This is yet more excellent news and should be considered tremendously exciting. The Oxford vaccine, as for the others we’ve heard about recently, is capable of generating 90% protection against COVID-19. Given the favorable stability seen for this vaccine, it has great potential to be delivered across the globe, achieving huge public health benefits.”

Dr. Griffin was not involved with the study.

11/20/2020 09:16 GMT — WHO release statement regarding remdesivir

In an article, which appears in BMJ, the World Health Organization (WHO) recommend “against the use of remdesivir in hospitalized patients with COVID-19.” This change in stance is a response to results from the WHO SOLIDARITY trial. The results first appeared on the preprint server medRxiv on October 15. 

The authors of the study, which investigated a number of COVID-19 interventions, conclude that “[r]emdesivir, [h]ydroxychloroquine, [l]opinavir, and [I]nterferon regimens appeared to have little or no effect on hospitalized COVID-19, as indicated by overall mortality, initiation of ventilation, and duration of hospital stay.”

The authors of the recent BMJ update explain that, although they could not categorically state that remdesivir affords no benefit, “there is no evidence based on currently available data that it does improve patient-important outcomes.”
