(Press-News.org) HMRI and University of Newcastle researcher, Professor Murray Cairns, along with his Precision Medicine team have discovered a way of predicting who will respond to blood pressure treatments to lower sodium in the body. Their findings were published this week in Circulation, a prestigious international cardiology journal.
Professor Cairns says, “High blood pressure – or hypertension related disease – kills up to 20 per cent of people. At least 30 per cent of the adult population has it – that’s one in three Australian adults – and only 30 per cent of those people get it under control.
“A 25% reduction in the prevalence of hypertension could save the Australian Government $34 billion per year,” says Professor Cairns.
Professor Cairns and his team have figured out how to use each person’s individual genetics to inform treatment.
“The way people respond to drugs is different. We can measure an individual’s genetic risk of developing high blood pressure with respect to the physiological systems responsible – including kidneys, heart or smooth muscle - and then target medications accurately,” says Professor Cairns.
Some hypertension medications work to lower sodium – and subsequently blood volume – in the body. Professor Cairns says that while many people have a genetic predisposition to high blood pressure that is triggered or exacerbated by a high salt modern diet, they will respond well to treatment that reduces sodium. He also says that for some people, salt is not a significant factor in their hypertension so they may benefit more from treatments that target other biological aspects of their genetic risk.
With 80 per cent of people ending up with some form of chronic disease, and 20 per cent with two or more, genetic insights driving precision medicine could have a massive impact on global health.
The team used real world data from the UK biobank in order to measure the interaction between sodium-associated genetic scores, sodium levels and blood pressure.

PITTSBURGH, Dec. 22, 2023 – A new study indicates that severity of amyloid deposition in the brain — not just age — may be key to determining who will benefit from new anti-amyloid therapies to delay the progression of Alzheimer’s disease.
University of Pittsburgh clinicians and scientists report that the accumulation of toxic amyloid beta clumps that signal Alzheimer’s disease pathology accelerates in old age but the baseline amyloid burden and the overall brain health going into this acceleration ...

This whirling image features a bright spiral galaxy known as MCG-01-24-014, which is located about 275 million light-years from Earth. In addition to being a well-defined spiral galaxy, MCG-01-24-014 has an extremely energetic core known as an active galactic nucleus (AGN) and is categorized as a Type-2 Seyfert galaxy. Seyfert galaxies, along with quasars, host one of the most common subclasses of AGN. While the precise categorization of AGNs is nuanced, Seyfert galaxies tend to be relatively nearby and their central AGN does not outshine its host, while quasars are very distant AGNs with incredible luminosities that outshine ...

Researchers at the University of Warsaw's Faculty of Physics with colleagues from Stanford University and Oklahoma State University have introduced a quantum-inspired phase imaging method based on light intensity correlation measurements that is robust to phase noise. The results of the research have been published in the prestigious journal “Science Advances”. The new imaging method can operate even with extremely dim illumination and can prove useful in emerging applications such as in infrared and X-ray interferometric imaging and quantum and matter-wave ...

When you eat a large meal, your stomach sends signals to your brain that create a feeling of fullness, which helps you realize it’s time to stop eating. A stomach full of liquid can also send these messages, which is why dieters are often advised to drink a glass of water before eating.
MIT engineers have now come up with a new way to take advantage of that phenomenon, using an ingestible capsule that vibrates within the stomach. These vibrations activate the same stretch receptors that sense when the stomach is distended, creating an illusory sense of fullness.
In animals who were given this ...

Obesity interventions, such as gastric bypass surgery, can alter the signaling of the vagal nerve, which plays a crucial role in regulating digestion. In addition to traditional obesity interventions, new weight-management medications, such as Wegovy, are becoming increasingly popular options for patients with obesity since they are non-invasive and require minimal lifestyle modifications. Developing a variety of non-invasive, convenient weight-management options for patients with obesity is essential to help reduce comorbidities such as diabetes, hypertension, cancer ...

A common stomach bacteria found in two thirds of the world population may be linked to a higher risk of Alzheimer’s disease, new research suggests.
The study, published in Alzheimer's & Dementia: The Journal of the Alzheimer's Association, investigated whether a clinically apparent Helicobacter pylori (H. pylori) infection increased the risk of Alzheimer's disease in people aged 50 and older. The prevalent infection can trigger indigestion, gastritis, ulcers, and even stomach cancer.
A team of McGill University researchers analyzed health data of over 4 million people in the United Kingdom aged 50 and above between 1988 and 2019. It found ...

Liver cancer screening among patients with cirrhosis almost doubled when they were mailed a signed order from their specialist, according to a new study from the Perelman School of Medicine at the University of Pennsylvania. However, when researchers added an incentive of $20 to the mailed orders, it made no difference in whether patients completed their screenings. The work was published this week in Hepatology Communications.
“Our findings show that an approach like this can meaningfully increase liver cancer surveillance, ...

Texas A&M University School of Public Health research on attitudes toward pet vaccination and how they may be linked with human vaccine hesitancy was the subject of a new study recently published in the journal Vaccine.
Simon Haeder, Ph.D., associate professor, analyzed data from an August 2023 survey of more than 2,000 dog and more than 1,400 cat owners to measure pet vaccination rates, perceptions of vaccines and support for pet vaccination requirements.
“Decreasing pet vaccination rates pose challenges to society for a number of reasons, including increased incidents ...
