If we don't get enough sleep we're apt to doze off in the day, but for some people, dozing off can signal rare disorder of the brain's sleep-wake cycles, and it plays havoc with their lives. In one 24-hour period our body undergoes a number of synchronised  biological changes, which are also linked to our mental health.

A question asked about COVID-19 was whether high doses of intravenous vitamin C could fight it. Two randomised controlled trials showed no benefit for COVID-19. But high-dose Vitamin C can benefit cancer treatment. Arthritis of the hands is common, painful, a bit of a mystery, and hard to treat. Researchers have trialled a drug commonly used for rheumatoid arthritis, and found some benefit. In Victoria, hospital researchers have been watching how COVID and lockdowns affected births there....

Two of the most common causes of death in Australia, and globally, are stroke and dementia. One cause of stroke is atrial fibrillation—an abnormal heart rhythm—it may also cause dementia. Faecal microbe (or poo) transplants are something we've talked about on the program, but until recently, they've not been widely available. In fact, the product is made in Australia. Australia is to participate in a survey of the experiences of patients in general practice who have a chronic illness.

Post-traumatic stress disorder (PTSD) is an extreme form of anxiety caused by the laying down of bad memories when someone is involved in a threatening situation. A new treatment has been developed for people to write about their experience, and feelings about the memory. Having your blood pressure checked at the doctor's or hospital is a health care basic. A recent trial has found a significant and possibly unexpected source or error: the size of the cuff, relative to the thinness or...

Australians will soon vote on changing the Australian Constitution to recognise First Nations people—the Voice to Parliament. When it comes to health, there's a strong evidence base for the Voice. In a slightly edited form, we hear again a conversation from a few weeks' ago with two key people working in this area. Over the past two decades, deaths from cardiovascular disease among people with diabetes have gone down, but is revealing other trends

3D printing is becoming an incredibly versatile modern tool—there’s scope  in engineering, manufacturing, architecture and design—as well as in several aspects of health care. Today we tour the Herston Biofabrication Institute—part of the Royal Brisbane and Women’s Hospital—where clinicians, academics, and industry work together in a state of the art facility.

To have you in the best physical condition before major surgery many surgeons send you for a pre-operative assessment by a physician—does it help? When a child has persistent cold symptoms, it might be sinusitis and require antibiotics. If a child faints it's really only a worry when it causes an injury. But there might be an abnormality of the heart's electrical system, called congential Long QT syndrome, and prompt parents to have their child checked.  Rehab after knee...

Mexico has implemented labelling of processed foods with large warnings if the unhealthy ingredients exceed globally agreed thresholds. New research has been looking into why sitting is bad—and how to change that. Women are being mislead by fertility tests which promote anti-Mullerian hormone—or AMH testing—which are not designed for general screening in the community. One of the side effects of having had babies and ageing in general is what used to be called prolapse—or uterine descent....

We heard today about a new test for ovarian cancer.  For a long time there's been a search for a way to reliably detect this cancer early on. Some men are prescribed testosterone-replacement therapy in middle age or older, but there's questions around how safe that is for their heart attack and stroke risk. In developing the cervical screening program one woman—Mary Papanicolaou—did a test every day, for 21 years—it's what we now call the PAP test. People tend to think they need seven or...

Metastatic cancer is for the spread of a cancer from a primary site to other parts of the body. There's no nationally consistent way of keeping track of how many of these cancer patients there are. A consortium of Australian cancer researchers has announced a program called the PrOSPect Initiative. It offers genetic profiling for people with advanced or rare cancers. Aerobic exercise reduces blood pressure, and resistance training prevents progression to diabetes in people at risk. But the...

To assess the heart health and stroke risk factors of the population, Australian GPs and cardiologists have referred to a study from the population of Framingham, Massachusetts, but last week the Heart Foundation replaced it with a tool based on New Zealand and Australian populations. An abnormal heart rhythm can mean observations by a cardiologist with a cumbersome and expensive Holter monitor. A team at Westmead Hospital and the University of Sydney have compared a simple finger electrode...

In health news Norman and Tegan discuss changes in the health system for medical termination of pregnancy; and about life span vs life expectancy in Australia. Alongside MDMA and psilocybin as treatments for mental health issues is ketamine—which shows promise in treatment-resistant depression. A common fracture in children comes from a fall onto an outstretched arm. Parents instinctively want to get an X-ray but an ultrasound can work just as well for most these cases.

Strength training is fundamental to most athletes' regimes, but the guidelines are overwhelmingly based on male data. An analysis of labelling on sports foods—things like protein shakes and bars—finds that the nutritional claims they make often don’t tally with the ingredients panel. Worry about memory loss is not uncommon, and not confined to an older age group, but measuring memory accurately needs refinement. Many Australians are prescribed opioids as relief for back pain, but the a...

If dementia is diagnosed before someone is 65 it's called 'younger onset' dementia, and it can occur while people still have family responsibilities. We talk with people who have been given this news, and to researchers looking to improve diagnosis and care. We think of breastfeeding as being quite natural, but it doesn't always come easily, and issues such as Breastfeeding Aversion Response (or BAR) are still under-researched.

A look at some of the big stories in health over the last week ... cough syrup, Duchenne gene therapy; chemo drugs in the US. Some new prescribing guidelines for opioids recommend an exit strategy—and the need for better support infrastructure. It was suspected that brain damage for some people with Parkinson's disease was due to chemical toxins—one of the probable culprits is an environmental contaminant. Having your tonsils out as a child used to be routine, but what about for...

A recent bus crash in the Hunter Valley claimed 10 lives. Trying to make sense of such tragic events often prompts a reach for advice that sounds right, but might not be. Therapy using psychedelic drugs is generally safe yet a review of its use found that adverse events were not properly assessed or not reported. In Canada cannabis was legalised 5 years ago for non-medical and recreational use. Public health researchers have asked if this legalisation had health impacts on mothers and their...

A recent study has looked at correlations between rates of (Australian) population obesity and searching online for anti-obesity and diabetes drugs—searches for a class of drugs called the GLP-1 agonists. You probably know the Australian Government has general exercise recommendations for adults, but what if you're in a high risk group? Does that change the amount of activity you should be doing? Peripheral arterial disease (PAD) is perhaps the ‘poor cousin’ of cardio-vascular disease. PAD...
