The global network led by the Oxford Maternal and Perinatal Health Institute (OMPHI) at the University of Oxford has published in the journal Lancet the results of the ‘2022 INTERCOVID Study’ conducted in 41 hospitals across 18 countries, including Ann & Robert H. Lurie Children’s Hospital of Chicago.
Just as a highly transmissible variant prompts officials to extend COVID-19 emergency status, one of the largest surveys ever conducted shows people are more willing to get vaccinated when health workers reveal how many others are doing so.
A new study led by scientists at La Jolla Institute for Immunology (LJI) shows how ideal antibodies against SARS-CoV-2 hit their marks. Now scientists are looking at how we might harness their power in new antibody therapeutics and even more effective COVID-19 vaccines.
The researchers screened a library of drugs using a mouse endothelial cell line to identify pathways that are involved in the regulation of Robo4 and found that two competitive SMAD signaling pathways appear to regulate Robo4 expression. When the researchers treated LPS-injected mice with a drug that inhibits ALK1-SMAD signaling, they observed increased Robo4 expression, decreased vascular permeability, and reduced mortality.
High levels of mucosal IgA antibodies in the airways protect against SARS-CoV-2 infection for at least eight months. Omicron infection generates durable mucosal antibodies, reducing the risk of re-infection.
Nonpharmaceutical interventions slowed the spread of COVID-19 and other infectious diseases but now, as NPIs are lifted, countries are seeing a resurgence in several respiratory diseases. In Chaos, scientists, using data from Hong Kong to develop their model, describe a threshold control method that can be used to predict the best time to lift NPIs without overwhelming the hospital systems when these other respiratory diseases inevitably surge back. They found that reintroducing NPI measures when a threshold of 600 severe cases is reached could ensure that the hospital system in Hong Kong is not overwhelmed by severely infected patients.
NEW YORK, NY – Jan. 17, 2023 – The American Thoracic Society is starting the new year poised to improve vaccination rates with three health system partners: University of Arizona/ Banner Health; West Virginia University Hospitals, Inc.; and San Francisco Health Network/ University of California.
A new test that ‘fishes’ for multiple respiratory viruses at once using single strands of DNA as ‘bait’, and gives highly accurate results in under an hour, has been developed by Cambridge researchers.
Results of the 18-month study, published in Lancet Regional Health - Americas and led by Amit Bahl, M.D., M.P.H., emergency medicine with Corewell Health East, formerly Beaumont Health, showed that while omicron cases had the highest hospital admission rates among children ages 0 to 17, serious, even deadly, cases of illness were less likely during omicron than during the delta and alpha variants. In fact, the odds of severe disease were 65% lower during omicron compared to alpha.
Researchers at Johns Hopkins Medicine say their new studies suggest that the first pandemic-accelerating mutation in the SARS-CoV-2 virus, which causes COVID-19, evolved as a way to correct vulnerabilities caused by the mutation that started the SARS-CoV-2 pandemic.
While COVID-19 boosters have been found to protect against infection, hospitalization, and severe illness, the waning of their protection has led to uncertainty about when it is most appropriate to get an additional booster shot.
Researchers identified and addressed a flaw in a commonly used pandemic model that can cause the model to severely underestimate disease spread.

There are so many unknowns about long COVID. Why is the range of symptoms so vast? How do pre-existing conditions play a role? Scientists have developed a machine learning tool to accelerate discoveries using actual patient data.
The long-term effects of infection on the immune system have long intrigued John Tsang, a Yale immunobiologist. After the body has faced down a pathogen, does the immune system return to the previous baseline? Or does a single infection change it in ways that alter how it will respond not only to a familiar virus but also to the next new viral or bacterial threat it faces?
Breaking research demonstrates the efficacy of two data analytics-based strategies that clinical labs employed to meet COVID-19 testing demands during the height of the pandemic. These findings, published in the Data Science Issue of AACC’s The Journal of Applied Laboratory Medicine, give labs a blueprint for using data analytics to ensure patient access to testing during future infectious disease outbreaks.
A three-dose regimen of a whole-parasite vaccine against malaria – called Plasmodium falciparum sporozoite (PfSPZ) vaccine – demonstrated safety and efficacy when tested in adults living in Burkina Faso, West Africa, which has endemic malaria.
Salmonella are food-borne pathogens that infect millions of people a year. To do so, these bacteria depend on a complex network of genes and gene products that allow them to sense environmental conditions.

On July 23, 2022, the World Health Organization (WHO) declared the current outbreak a public health emergency of international concern.
Artificial intelligence could help doctors dynamically determine safe and effective medication dosing for unstable ICU patients. Predicting the right dose of medication that a critically ill child in the ICU will require in the future is a huge challenge for clinicians. FDA prescribing guidelines generally assume that patients are stable enough so that dosing for a given group is usually unchanged during treatment, but this ‘one size fits all’ approach to medication dosing does not accurately target the condition of each individual patient over time.
