Dangerous Fungal Infection Sees a Dramatic Increase in US Hospitals

Cases of the fungal infection Candida auris are rising rapidly and coming from more sources too, a new US study reveals.

C. auris was first reported in the US in 2016 and is considered an “urgent antimicrobial resistance threat” in hospitals, according to the Centers for Disease Control and Prevention (CDC).

Focusing on a large health system in Miami, Florida, the new research found that reported clinical cases had risen from 5 in 2019 to 115 in 2023 – a considerable jump of 2,200 percent in four years.

A Circuit Linking DNA Repair, Inflammation & Aging is Found

As our bodies grow, cells proliferate to form tissues, and cells frequently have to be repaired or replaced throughout life. But the genome can also become less stable over time, or may pick up mutations that can lead to disease; these and other processes can cause cells to enter a state in which they stop dividing, known as senescence. Senescent cells become more common as we age. There also tends to be more inflammation as we age, but the link between increasing instability in the genome and inflammation is not well understood. Now scientists have reported a direct connection between DNA instability and inflammation in senescent cells. The findings have been reported in Nature Communications.

“In addition to no longer growing and proliferating, the other hallmark of senescent cells is that they have this inflammatory program causing them to secrete inflammatory molecules,” noted senior study author Peter Adams, Ph.D., director and professor of the Cancer Genome and Epigenetics Program at Sanford Burnham Prebys.

Millions of Brits could be ‘cancer resistant’ and discovery could help find a cure

MILLIONS of people may be “cancer-resistant”, according to experts.

Scientists are being offered up to £20million to work out why some are tumour-proof.

About one in two Brits get cancer but tumours do not develop in everyone who would be expected to get one, such as heavy smokers.

Nanotechnology could improve odds in treating aggressive breast cancers

University of Queensland researchers are designing nanotechnology they believe could improve how we treat the most aggressive form of breast cancer.

Professor Chengzhong (Michael) Yu and his team are developing novel nanoparticles that could dramatically increase the effectiveness of immunotherapies when treating triple-negative breast cancer (TNBC).

TNBC is aggressive, fast-growing and accounts for 30 per cent of all breast cancer deaths in Australia each year, despite making up only 10 to 15 per cent of new cases.

Professor Yu, from UQ’s Australian Institute for Bioengineering and Nanotechnology (AIBN), said a new solution was needed because TNBC cancer cells lacked the proteins targeted by some of the treatments used against other cancers.

494,000 Americans Affected As Massive Data Breach Exposes Names, Financial Records, Medical Data, Social Security Numbers and More: Report

A cybersecurity incident affecting nearly half a million people has exposed personal, financial and medical information.

The mobility and assistive solutions provider Numotion says 494,000 customers are affected by a data breach witnessed between September 2nd, 2024, and November 18th, 2024, reports Security Week.

Numotion says an unknown entity managed to access the email accounts of the firm’s employees without authorization several times.
