Multi-cancer blood tests offer promise but face skepticism: Multi-cancer early detection blood tests that analyze tumor DNA in the bloodstream are being promoted as a way to detect dozens of cancers from a single sample; however, early trial results, including a large study of the Galleri test, have not yet shown a significant reduction in late-stage cancer diagnoses and have raised concerns about missed cancers and false positives. Experts caution that although advances are being made, MCEDs’ accuracy and ability to improve patient outcomes remain uncertain.

In the first reported case of its kind, surgeons in China connected a liver failure patient to a genetically modified pig liver that filtered his blood for nearly three (3) days while he awaited a human transplant. The procedure served as a temporary “bridge” therapy until a donor organ became available, highlighting the potential of xenotransplantation to support patients with severe organ failure.

The core mission of the US Food and Drug Administration’s (FDA) inspections program, as well as how it prioritizes inspections, has remains unchanged despite recent leadership changes at the agency, said Ivy Sweeney, Deputy Director of the Office of Human and Animal Drug Inspectorate (OHADI).

A study published in Cell Stem Cell found that a single dose of mesenchymal stem cells can improve endurance in older adults with frailty. The highest dose resulted in a 20% improvement in a six-minute walk test. The stem cells, derived from donated bone marrow, do not require immunosuppressive medications.

Vaccine pioneer warns of resurgence in vaccine-preventable diseases: Stanley Plotkin, a pioneering vaccine scientist often called the “godfather of vaccines,” reflects on his career developing the rubella and rotavirus vaccines and warns that declining vaccination rates could allow previously controlled childhood diseases to return. “In the absence of disease, people are less worried, and they ask themselves: Why should I vaccinate the child because there’s no disease around?” Plotkin said.

Spinal cord organoids show promise for paralysis therapy: Research with mice previously showed that a single injection of a peptide gel helped animals regain walking after severe spinal cord injury, and new studies with human stem cell-derived spinal cord organoids found the same treatment reduced scar tissue and encouraged nerve fibers to grow after injury. The gel forms a soft scaffold that actively interacts with nerve cells to promote regrowth, targeting the scar barriers that normally prevent recovery after paralysis.

Decades-old drug may help prevent Alzheimer’s disease: A study published in Science Translational Medicine found that the decades-old anti-seizure drug levetiracetam reduced production of amyloid-beta 42 in research with engineered mouse models and human neurons. The Researchers found that levetiracetam works by maintaining amyloid precursor protein on the cell surface, favoring a non-amyloidogenic pathway.

Mouse research shows skull veins actively protect the brain: Research with mice and human tissue found that large veins in the skull actively pulse to drain blood and cerebrospinal fluid and shift their cell borders to allow immune cells to patrol, helping protect the brain from infection, inflammation and pressure buildup. The team also showed that the molecule CGRP widens these veins, which might explain how migraine drugs that target CGRP work. (CGRP stands for calcitonin gene-related peptide, a 37-amino acid protein acting as a neurotransmitter and vasodilator involved in transmitting pain signals).

Study with mice advances universal vaccine against respiratory threats: A universal vaccine candidate developed by Stanford Medicine researchers offers protection against a wide range of bacteria, respiratory viruses and allergens in a study with mice published in the journal Science. The intranasal vaccine integrates innate and adaptive immunity, providing broad lung protection for several months. “If it ultimately proves safe and effective in humans, the potential impact could be transformative: simplifying seasonal vaccination and improving readiness for emerging respiratory threats,” Researcher Bali Pulendran said.

Although we adore our feline friends, it does not often seem like we have much in common with them — unless, of course, you also have a passion for attacking furniture legs and licking your own rear. When it comes to health, however, cats are exposed to many of the same environmental risks as their owners and they fall victim to many of the same ailments. Cancer, for example, is one of the leading causes of illness and death in cats; however, the genetics of this disease in felines remain relatively unexplored.
