Post-acute sequelae SARS-CoV-2 infection (PASC), also known as long-haul COVID-19, is positively associated with posttraumatic stress disorder (PTSD), says new research presented at Physiatry ’23, the Association of Academic Physiatrists (AAP) annual meeting.
Global data shows nearly 10 per cent of severe COVID-19 cases involve a secondary bacterial co-infection – with Staphylococcus aureus, also known as Staph A., being the most common organism responsible for co-existing infections with SARS-CoV-2.
A UCLA-led team has developed an inexpensive, universal oral COVID-19 vaccine that prevented severe respiratory illness and weight loss when tested in hamsters, which are naturally susceptible to SARS-CoV-2. It proved as effective as vaccines administered by injection or intranasally in the research. If ultimately approved for human use, it could be a weapon against all COVID-19 variants and boost uptake, particularly in low- and middle-income countries, and among those with an aversion to needles.
Human papillomaviruses (HPVs) cause several cancers in both men and women, including 91% of cervical cancers, 91% of anal cancers and 75% of vaginal cancers, according to the Centers for Disease Control and Prevention. Most of these cancers are caused by just a handful of HPV virus types.
Malaria control programs in Amazonian Peru helped reduce the incidence of the deadly parasitic disease by 78 percent. That is, until the programs ceased to operate.
Early COVID-19 pandemic suspicions about dogs’ resistance to the disease have given way to a long-haul clinical data gap as new variants of the virus have emerged.
A new study from Boston University Chobanian & Avedisian School of Medicine has found that a brief stigma intervention that specifically targets people with HIV who inject drugs was effective in increasing engagement in substance use care as well as improving their ART adherence.
The magnitude and quality of a key immune cell’s response to vaccination with two doses of the Pfizer-BioNTech COVID-19 vaccine were considerably lower in people with prior SARS-CoV-2 infection compared to people without prior infection, a study has found.
Scientists from the French National Reference Center for Escherichia coli, Shigella and Salmonella at the Institut Pasteur who have been monitoring Shigella in France for several years have detected the emergence of extensively drug-resistant (XDR) strains of Shigella sonnei.
COVID-19 is associated with an increased risk of developing long-term gastrointestinal disorders, including irritable bowel syndrome.
Individuals who are obese may be more susceptible to severe COVID-19 because of a poorer inflammatory immune response, say Cambridge scientists.
Staphylococcus aureus, Clostridioides difficile, Candida auris, Drug-resistant Shigella. These bacteria not only have difficult names to pronounce, but they are also difficult to fight off. These bacteria may infect humans and animals, and the infections they cause are harder to treat than those caused by non-resistant bacteria. Antimicrobial resistance is an urgent global public health threat.
Influenza viruses have an enormous impact in the U.S., with an estimated 25 million illnesses and 18,000 deaths in the 2022-23 flu season alone. However, the majority of virus particles are not infectious or are only partially infectious. How, then, do they become such a contagious and deadly virus?
New research from Leela Nageswaran, assistant professor of operations management in the University of Washington Foster School of Business, considers whether individuals should be able to select their vaccine type.
Researchers may have found why viral infections hit males more severely than females. They found that female mouse and human NK cells have an extra copy of an X chromosome-linked gene called UTX. UTX acts as an epigenetic regulator to boost NK cell anti-viral function, while repressing NK cell numbers.
A Kaiser Permanente study confirms the benefit of nirmatrelvir-ritonavir, also known as Paxlovid, as an early-stage treatment to prevent hospitalization for people with mild to moderate COVID-19, regardless of prior immunity or age. The study was published March 15, 2023, in Lancet ID.
Research is shedding light on why ‘breakthrough’ Omicron infections occur in vaccinated individuals and suggests those who are both vaccinated and experienced previous infection have better protection against getting sick again.
New UC Riverside research makes it likely that proteins responsible for activating mosquito sperm can be shut down, preventing them from swimming to or fertilizing eggs.
For the past few years, how a virus triggered a global pandemic has dominated conversations. Now, thanks to the TV show “The Last of Us” (about an apocalypse triggered by brain-eating ’shrooms), fungi have infected popular culture.
A group of researchers have used the Advanced Photon Source to look at monoclonal antibodies to subvert the “shield” of the Lassa virus, potentially paving the way for new therapies.
It's sleep awareness week, according to the National Sleep Foundation. It’s important to understand how sleep deprivation can impact your health. Most people recognize that if they don’t get enough sleep, their mood and memory will suffer the next day.
COVID-19 has caused significant global panic after its rapid emergence more than 3 years ago.
During the pandemic, it became clear that children who contracted COVID-19 became less ill than adults.
Researchers at Cummings School of Veterinary Medicine at Tufts University found that an outbreak of highly pathogenic avian influenza (HPAI) was associated with the deaths of more than 330 New England harbor and gray seals along the North Atlantic coast in June and July 2022, and the outbreak was connected to a wave of avian influenza in birds in the region.
Long before COVID-19, washing and sterilizing hands were known to help prevent the spread of infections such as influenza, and hand hygiene practices were especially important in high-risk areas, such as hospitals. So it was something of a public health boon that COVID-19 abruptly increased hand hygiene awareness.
Many highly sensitive diagnostic tests for viral diseases still require complicated techniques. But now, a team reporting in ACS Central Science has developed a sensitive method that analyzes viral nucleic acids quickly and can be completed in one step with “glow-in-the-dark” proteins.
A recent study in the Journal of Biological Chemistry has revealed the secret behind an evolutionary marvel: a bacteriophage with an extremely long tail. This extraordinary tail is part of a bacteriophage that lives in inhospitable hot springs and preys on some of the toughest bacteria on the planet.
A population data linkage study using anonymised primary and secondary care health records in Swansea University’s SAIL Databank has revealed that in 2020 and 2021, fewer people in Wales were being diagnosed with long-term conditions than expected.
A patient presenting with painful, swirling skin lesions, chills, and weight loss was found to be suffering from erythema gyratum repens (EGR), a rare and striking skin condition that is associated with underlying malignancy in most cases, but in some cases can stem from an autoimmune disease, messenger RNA-based vaccines against COVID-19, or in rare cases, tuberculosis (TB). The case report from authors at Stanford University is published in Annals of Internal Medicine.
A team of faculty from Wayne State University has discovered new technology that will quickly and easily detect active Mycobacterium tuberculosis (TB) infection antibodies.
If you’re a fan of HBO’s post-apocalyptic series “The Last of Us” – or the video game that inspired it – you’ve probably heard the term Cordyceps. In the show, the parasitic fungus has mutated, graduating from infecting insects to humans – transforming them into mind-controlled zombies. But it’s not all science fiction. Niels-Viggo Hobbs Ph.D. ’16, a University of Rhode Island assistant teaching professor in biological sciences, lends his expertise to carefully walk us through the world of Cordyceps.
A whole new world of antibiotics is waiting inside the viruses that infect bacteria. Our scientists are making it easier to study them.
The next pandemic that cascades through the human population could be caused by a new influenza virus strain concocted in animals, against which humans will have little to no immunity.
Sleeping fewer than six hours per night around the time of vaccination was associated with a robust decrease in antibody response, researchers found.
In reviewing data from previous studies, a team lead by researchers at the University of Chicago and the French National Institute of Health and Medical Research (Inserm) found that individuals who had fewer than six hours of sleep per night in the days surrounding vaccination had a blunted antibody response. That indicates efforts to promote heathy sleep duration ahead of an immunization could be an easy way to improve vaccine effectiveness.
