COVID-19 outbreaks in French nursing homes almost certainly started in staff - and none of measures put in place stopped the virus from taking hold, new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, shows.
Residents of long-term care facilities represent a small fraction of the general population but account for a disproportionate number of SARS-CoV-2-related deaths in many countries.
The flu vaccine may provide vital protection against COVID-19, new research being presented at the European Congress of Clinical Microbiology & Infectious Diseases (ECCMID), held online this year, concludes.
An analysis of patient data from around the world strongly suggests that the annual flu shot reduces the risk of stroke, sepsis and DVT in patients with COVID-19. Patients with COVID-19 who had been vaccinated against flu were also less likely to visit the emergency department and be admitted to the intensive care unit (ICU).
DALLAS, July 12, 2021 -- People of South Asian ancestry have more than double the risk of developing heart disease compared to people of European ancestry, yet clinical risk assessment calculators used to guide decisions about preventing or treating heart disease may fail to account for the increased risk, according to new research published today in the American Heart Association's flagship journal Circulation.
A novel method of gene therapy is helping children born with a rare genetic disorder called AADC deficiency that causes severe physical and developmental disabilities.
USC researchers have achieved a better way to identify elusive DNA variants responsible for genetic changes affecting cell functions and diseases.
Scientists have produced the first fine-detail molecular blueprints of a bacterial enzyme known as Lit, which is suspected to play a "stealthy" role in the progression of infection by reducing the immune response.
Blueprints such as these allow drug designers to uncover potential weaknesses in bacterial arsenals as they seek to develop new therapeutics that may help us win the war against antibiotic resistance.
Oncotarget published "A novel E2F1-regulated lncRNA, LAPAS1, is required for S phase progression and cell proliferation" which reported that long non-coding RNAs are major regulators of many cellular processes, including cell cycle progression and cell proliferation.
Inhibition of LAPAS1 expression increases the percentage of S phase cells, and its silencing in synchronized cells delays their progression through S phase.
Imagine sitting out in the sun, reading a digital screen as thin as paper, but seeing the same image quality as if you were indoors. Thanks to research from Chalmers University of Technology, Sweden, it could soon be a reality. A new type of reflective screen - sometimes described as 'electronic paper' - offers optimal colour display, while using ambient light to keep energy consumption to a minimum.
Researchers have identified a specialized protein that appears to help prevent tumor cells from entering the bloodstream and spreading to other parts of the body.
"We have discovered that this protein, TRPM7, senses the pressure of fluid flowing in the circulation and stops the cells from spreading through the vascular system," said Kaustav Bera, a Johns Hopkins University PhD candidate in chemical and biomolecular engineering and a lead author of the study, which was done with colleagues at the University of Alberta and Universitat Pompeu Fabra.
Nashville, Tenn. (4:14 p.m. EDT--July 9, 2021)--Orthopedic surgeons know that knee surgeries that require revisions have inferior outcomes compared with primary surgeries but until now, the reason for this was unknown. Today a team of orthopedic physicians reports that opting for a transtibial surgical approach and choosing an inference screw for femoral and tibial fixation will improve the patient's odds of having a significantly better six-year clinical outcome.
Plants have microscopically small pores on the surface of their leaves, the stomata. With their help, they regulate the influx of carbon dioxide for photosynthesis. They also use the stomata to prevent the loss of too much water and withering away during drought.
The stomatal pores are surrounded by two guard cells. If the internal pressure of these cells drops, they slacken and close the pore. If the pressure rises, the cells move apart and the pore widens.
We know that turning goals into a game can increase people's physical activity. We also know that financial incentives can be effective, especially when they're framed in a way where people lose money if they don't reach their goals. But a new Perelman School of Medicine at the University of Pennsylvania study adds to evidence that combining the two can result in significant gains.
What The Study Did: This survey study examined disparities in COVID-19 vaccine acceptance and approaches to improve vaccination rates among adults in China.
Authors: Jingjing Ma, Ph.D., of Peking University in Beijing, is the corresponding author.

A research team co-led by UCL (University College London) has solved a decades-old mystery as to how Jupiter produces a spectacular burst of X-rays every few minutes.
The X-rays are part of Jupiter's aurora - bursts of visible and invisible light that occur when charged particles interact with the planet's atmosphere. A similar phenomenon occurs on Earth, creating the northern lights, but Jupiter's is much more powerful, releasing hundreds of gigawatts of energy, enough to briefly power all of human civilisation*.
A new study (the ATOMIC2 trial), presented at this year's European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) and published simultaneously in The Lancet Respiratory Medicine, shows the antimicrobial drug azithromycin - already approved for use in multiple infections - does not prevent mild COVID-19 cases progressing to hospitalisation or death.
