NewsRevealed: new factor associated with the risk of severe COVID-19 in people with obesity
By analyzing samples from obese non-diabetics, researchers found that high blood levels of saturated fatty acids cause pre-activation of innate immune cells that, when infected with SARS-CoV-2, produce elevated levels of inflammatory molecules.

NewsCommon respiratory infections may have protected children from COVID-19, study suggests
Analyzing nasal swabs taken during the pandemic, researchers suggest that the frequent presence of other viruses and bacteria may have helped to protect children from the worst effects of COVID-19 by boosting their immune systems.

NewsThink you might have COVID? Wait two days before you test, study suggests
researchers unveil a new mathematical model to quickly answer such questions, not only for COVID but also for emerging rapid tests for respiratory syncytial virus (RSV), the flu and other infectious diseases.

NewsResearchers describe a new hybrid antibody that fights streptococcus and Covid-19
Scientists who developed antibodies targeting both SARS-CoV-2 and streptococcal bacteria, from patients infected with these diseases, have described a new hybrid antibody created by combining parts from two IgG subgroups.

NewsSocial media use is associated with more frequent vaccination
Researchers have found that more social media use correlates with more vaccination – though the reason for this relationship is different for Democrats and Republicans.
-
NewsCannabis use tied to increased risk of severe COVID-19
Researchers have found that people who reported using any form of cannabis at least once in the year before developing COVID-19 were significantly more likely to need hospitalization and intensive care than were people with no such history.

NewsMetformin and AGIs show potential for improved outcomes in COVID-19 patients with type 2 diabetes
A new study has found a significant association between metformin and AGI use and reduced all-cause mortality in COVID-19 patients with Type 2 diabetes. Conversely, insulin use was linked to an increased risk of death.

NewsResearchers advise strengthening immunity against COVID-19 in people with cancer
Researchers who led a study on the effectiveness of vaccines against COVID-19 among cancer patients in Catalonia, have recommended administering additional doses of the vaccine among this risk population.

NewsScientists uncover risk factors for long Covid
A study has found that people with a milder Covid-19 infection—including those who were vaccinated against SARS-CoV-2 and those who were infected with an Omicron variant—were more likely to recover quickly.

NewsMothers have lower risk of caesarean births after COVID vaccination
Pregnant women who have been vaccinated against Covid-19 are less likely to have a caesarean section or experience hypertension, according to a study.

NewsIntranasal COVID-19 vaccine headed to clinical trials
CyanVac will sponsor a randomized, double-blind Phase 2b study to compare the efficacy and safety of CVXGA, its intranasal vaccine candidate designed to protect against COVID-19, against an FDA-approved mRNA-based COVID-19 vaccine.

NewsNew study helps explain how elderly individuals react differently to COVID-19 than young people
A new study suggests that a suppressed immune landscape is a key driver of age-associated endothelial dysfunction during COVID-19.

NewsFeeling rough after your COVID shot? That means it’s working!
Side effects of the Covid vaccine may include tiredness, muscle and joint pain, chills, headache, fever or nausea, but a new study finds that the symptoms indicate a robust immune response that is likely to lessen the chances of infection.

NewsStudy finds no association between COVID-19 vaccines and stillbirths
In a new study funded by the U.S. Centers for Disease Control and Prevention, researchers found “no association between COVID-19 vaccination and stillbirth”.

NewsVirus that causes COVID-19 can remain in sperm for 110 days after infection
Researchers detected SARS-CoV-2 in male reproductive cells under the microscope even when PCR testing failed to detect the virus in semen. The discovery serves as a warning of possible implications for natural conception and assisted reproduction.
-
NewsVaccine approach offers promise to induce longer-lasting protective immunity against COVID-19
A scientific team has engineered a COVID-19 vaccine that induced – in pre-clinical models – very long-lasting, protective immunity against SARS-CoV-2 virus with a single-shot immunisation.
-
NewsOral nucleoside antiviral is progressing toward future pandemic preparedness
Oral obeldesivir has been shown to reduce disease severity in mice infected with one of several different coronaviruses, including SARS-CoV-2 (which causes COVID-19), SARS-CoV and MERS-CoV.
-
NewsPathway into cell influences the outcome of SARS-CoV-2 infection
The protein TMPRSS2 acts as a helper to bring the virus into the cell via the receptor ACE2. This TMPRSS2-mediated uptake significantly alters the immune response of the host cells and drives the evolution of the virus, a new study shows.
-
NewsScientists develop new nanoscale way to see viruses in action
A new, nano-scale look at how the SARS-CoV-2 virus replicates in cells may offer greater precision in drug development, scientists report.

NewsStatisticians call for rigour and transparency in the evaluation of diagnostic tests
Recommendations designed to reframe the evaluation of in vitro diagnostic tests have been published - intended to help prevent future scenarios in which IVDs are marketed widely, but later attract serious concerns about the standards applied to their evaluation.
