The time has come and gone for universal masking in healthcare settings, according to healthcare epidemiologists and infectious diseases experts from healthcare systems throughout Boston and beyond. In a commentary published in Annals of Internal Medicine and co-authored by experts from Mass General Brigham, Beth Israel Lahey Health, Tufts Medicine, the VA Healthcare System Boston, and other healthcare systems across the country, the authors describe the changing context and conditions of the pandemic and outline why universal masking should no longer be required in healthcare settings. “While critically important in the earlier ...

Hospital inpatients have better prospects of surviving a cardiac arrest in large hospitals and well-resourced wards, and daytime cardiac arrests are also associated with better chances of survival, a University of Gothenburg thesis shows. Cardiac arrest means that the heart stops pumping blood. Within seconds, unconsciousness occurs; within minutes, brain cells start dying, causing irreparable damage. The key to enhancing the patients’ chances of survival is restoring the circulation of oxygenated blood in the body. ...

A randomised clinical trial is looking at whether faecal microbiota transplantation (FMT) from healthy donors into adults with early-stage amyotrophic lateral sclerosis (ALS – one of the most common forms of motor neurone disease) can modulate the immune reaction during inflammation responses that characterise disease progression, and aims to investigate the relationship between specific gut bacteria and their action on immune system cells. The preliminary findings by Dr Alessandra Guarnaccia from Columbus-Gemelli University Hospital IRCCS, Rome, Italy and ...

The steps taken by a London hospital to prevent an outbreak of measles will be detailed at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark (15-18 April). Measles, which is highly contagious, can cause serious and potentially life-threating illness and complications including blindness, encephalitis (swelling of the brain) and pneumonia.  Pregnant women, infants and severely immunocompromised individuals are at highest risk. Contracted when pregnant, it can cause low birth weight babies, premature birth, miscarriage or stillbirth. It usually starts with cold-like symptoms, followed by a rash a few days later.  ...

AI software can accurately detect TB from chest X-rays, a study being presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Copenhagen, Denmark, (15-18 April), shows.

Salmonella infections cause about a million deaths a year worldwide, and there is an urgent need for better vaccines for both typhoid fever and non-typhoidal Salmonella disease. New work from researchers at the UC Davis School of Veterinary Medicine shows how memory T cells, crucial for a vaccine that induces a powerful immune response, can be recruited into the liver in a mouse model of Salmonella.  The work was published April 11 in Proceedings of the National Academy of Sciences.  “Understanding the immunology is key to developing a better vaccine,” said Professor Stephen McSorley, ...

This planet of 8 billion people is bumping up against its ecological limits, and researchers are trying to quantify the effect of human activity on these finite resources. Some keep tallies of how much carbon they contribute to the atmosphere, others measure direct and indirect water consumption or keep tabs on the amount of land that our food habits demand. Each of these “footprints” offers an estimate of the impacts individuals and institutions have on the wider world, and are useful — but are flawed, according to geographer Chris ...

Berkeley — Rates of school discipline fluctuate widely and predictably throughout a school year and increase significantly faster for Black students than for their white counterparts, University of California, Berkeley, researchers have found.   A new study published today in the journal Proceedings of the National Academy of Sciences documents for the first time the “dynamic” nature of student discipline during an academic year. Daily rates of punishment across all schools in the study ratchet up in the weeks before Thanksgiving break, decline immediately ...

Chronic wounds are a major health problem for diabetic patients and the elderly – in extreme cases they can even lead to amputation. Using electric stimulation, researchers in a project at Chalmers University of Technology, Sweden, and the University of Freiburg, Germany, have developed a method that speeds up the healing process, making wounds heal three times faster. There is an old Swedish saying that one should never neglect a small wound or a friend in need. For most people, a small wound does not lead to any serious complications, but many common diagnoses ...

Spiders that don’t weave good silk don’t get to eat. The silk spiders produce which creates their webs is key to their survival – but spiders live in many different places which require webs fine-tuned for local success. Scientists studied the glue that makes orb weaver spiders’ webs sticky to understand how its material properties vary in different conditions. “Discovering the sticky protein components of biological glues opens the doors to determining how material properties evolve,” said Dr Nadia Ayoub of Washington and Lee University, co-corresponding author of the study ...

LA JOLLA, CA—A new therapeutic designed by Scripps Research chemists can alter the molecular structure of the potent opioid carfentanil, inactivating the opioid and reversing a carfentanil overdose. The compound, which is described in an ACS Pharmacology & Translational Science paper published on April 17, 2023, and hasn’t yet been studied in humans, works in a fundamentally different way than existing treatments for opioid overdose. Carfentanil is up to 10,000 times more potent than morphine and 100 times stronger than fentanyl, making it one of the deadliest opioids. It is typically only used as a tranquilizer ...

Putting on your workout clothes and getting to the gym can feel like a slog at first. Eventually, you might get in the habit of going to the gym and readily pop over to your Zumba class or for a run on the treadmill. A new study from social scientists at Caltech now shows how long it takes to form the gym habit: an average of about six months.    The same study also looked at how long it takes health care workers to get in the habit of washing their hands: an average of a few weeks.    “There is no magic number for habit formation,” says Anastasia Buyalskaya (PhD ’21), now an assistant professor of marketing at HEC Paris. Other authors ...
