A new study published in the New England Journal of Medicine reports the identification of a previously unknown genetic cause of a late-onset cerebellar ataxia, a discovery that will improve diagnosis and open new treatment avenues for this progressive condition.

Researchers from the University of Jyväskylä and the Central Finland Health Care District have developed an AI based neural network to detect an early knee osteoarthritis from x-ray images. AI was able to match a doctors’ diagnosis in 87% of cases. The result is important because x-rays are the primary diagnostic method for early knee osteoarthritis. An early diagnosis can save the patient from unnecessary examinations, treatments and even knee joint replacement surgery.

Autoimmune diseases are thought to be the result of mistaken identity. Immune cells on patrol, armed and ready to defend the body against invading pathogens, mistake normal human cells for infected cells and turn their weapons on their own healthy tissues. In most cases, though, finding the source of the confusion the tiny fragment of normal human protein that looks dangerously similar to a protein from a pathogen  has been challenging for scientists.

Besides the skin, the digestive tract is the tissue that is most exposed to environmental influences such as bacteria and viruses. Therefore, cells that form these barriers to the interior of the body also have special defence mechanisms. A research team led by Professor Dr Thorsten Hoppe has now shown that RNA interference, or RNAi for short, which is known to be a viral defence mechanism, also prevents the overproduction of the body’s own proteins in intestinal cells.

A small molecule inhibitor that attacks the difficult to target, cancer-causing gene mutation KRAS, found in nearly 30 percent of all human tumors, successfully shrunk tumors or stopped cancer growth in preclinical models of pancreatic cancer, researchers from Penn Medicine’s Abramson Cancer Center showed, suggesting the drug is a strong candidate for clinical trials. The study was published today in Cancer Discovery, a journal of the American Association for Cancer Research.

Preventing metastasis – the development of cancer cells beyond their original location – remains one of the major goals of current cancer research. Most malignant tumor cells metastasize by exploiting abnormal leakage from blood vessels. New work looks to further explore the role of how the alignment of endothelial cells, which line blood vessels, plays a role in the spread of cancer.

Scientists have identified a drug that can be repurposed to prevent COVID-19 in research involving a unique mix of ‘mini-organs’, donor organs, animal studies and patients.

Novartis announced the pivotal Phase III PSMAfore study with PluvictoTM (INN: lutetium (177Lu) vipivotide tetraxetan), a prostate-specific membrane antigen (PSMA)-targeted radioligand therapy, met its primary endpoint. Pluvicto demonstrated a statistically significant and clinically meaningful improvement in radiographic progression-free survival (rPFS) in patients with PSMA–positive metastatic castration-resistant prostate cancer (mCRPC) after treatment with androgen-receptor pathway inhibitor (ARPI) therapy, compared to a change in ARPI1.

Adding a daily ounce of peanuts or about a teaspoon of herbs and spices to your diet may affect the composition of gut bacteria, an indicator of overall health, according to new research from Penn State. In two separate studies, nutritional scientists studied the effects of small changes to the average American diet and found improvements to the gut microbiome.
