Health Kick Podcast: Alterity Therapeutics

Stockhead's health and biotech expert Tim Boreham is back in the studio for another instalment of the Health Kick Podcast.
In this episode, Tim speaks with Alterity Therapeutics (ASX:ATH) CEO Dr David Stamler, who sheds light on a little-known but devastating neurological condition, multiple system atrophy (MSA).
MSA may not have the public awareness of Parkinson's or ALS, but it's every bit as serious, and Alterity is aiming to change that.
With no approved treatments currently available, MSA represents a major unmet clinical need.
Alterity's lead candidate, ATH434, is designed to address a unique biological mechanism involving iron imbalance in the brain.
Tune in to hear how ATH434 is showing promise in slowing disease progression, the science behind iron maldistribution in neurodegenerative disease, and how Dr Stamler's decades of FDA drug development experience is helping drive this program forward.
This podcast was developed in collaboration with Alterity Therapeutics, a Stockhead advertiser at the time of publishing.

Widespread PFAS exposure, but cancer risk ‘low,' experts confirm

There is 'considerable concern' among communities about exposure to so-called 'forever chemicals' found in everyday products and their potential health risks. However, after thoroughly reviewing the evidence, experts say the health effects appear to be small and individual blood testing offers no clear medical benefit. The NSW Health Expert Advisory Panel on PFAS (per- and polyfluoroalkyl substances) has released its final report, delivering clear guidance on the health effects of these widely found 'forever chemicals', the value of blood testing, and the best ways to communicate risks to communities. PFAS have been used since the 1940s in products resistant to heat, stains, grease, and water, but concerns have grown worldwide about their presence in the environment and potential health impacts. The panel, made up of leading clinical experts across toxicology, oncology, cardiology, public health, and risk communication, evaluated the latest Australian and global research to inform health advice. While acknowledging the body of research for health effects related to PFAS is 'large and still growing', the panel concluded that the health effects of PFAS 'appear to be small'. It noted links between PFAS exposure and conditions including high cholesterol, reduced kidney function, immune system changes, hormone alterations, liver enzyme changes, menstruation issues, lower birthweight, pregnancy high blood pressure, and some cancers. However, the panel stressed the evidence was inconsistent, with 'limited evidence of a dose-response relationship' and difficulty separating PFAS effects from other factors that can affect health, especially in studies with PFAS levels similar to the general population. It also highlighted the influence of bias and confounding factors such as smoking, diet, and age. Addressing widespread public concern about cancer, the panel said it remained confident that the absolute cancer risk from PFAS was low based on the human epidemiological studies and levels of exposure in the Australian population. The panel noted that while the International Agency for Research on Cancer (IARC) classified PFOA as 'cancer causing' and PFOS as 'possibly cancer causing', IARC's findings didn't specify safe exposure levels, how much exposure increases risk, or how big that risk might be. PFOA (perfluorooctanoic acid) and PFOS (perfluorooctane sulfonate) are specific types of PFAS. The panel stressed that, despite these hazard classifications, the actual cancer risk from PFAS in Australia was low based on studies and typical exposure levels. One of the panel's strongest messages is that there is 'no clinical benefit' for an individual to have a blood test for PFAS. The report stated that PFAS chemicals appeared in more than 95 per cent of people tested, showing widespread exposure from multiple sources. Because PFAS are so common, the expert panel said blood tests were hard to interpret and didn't predict health outcomes, so it didn't recommend individual testing. Although levels have been declining over the past 20 years, high background exposure makes studying health effects challenging. The panel supports ongoing population monitoring to track changes This stance differs from 2022 guidance by the US National Academies of Science, Engineering, and Medicine (NASEM), which suggested blood testing might guide clinical care. The NSW panel pointed out limitations in NASEM's approach, including reliance on studies with small effects and possible bias, and noted that US agencies like the CDC and ATSDR have not adopted NASEM's recommendations for individual blood testing. The panel also advised against interventions such as phlebotomy or cholesterol-lowering medications to reduce PFAS in the blood, calling their benefits 'uncertain' and warning they 'may cause harm' like anaemia or medication interactions. Instead, clinicians are urged to focus on 'usual preventative health interventions' to support patients. Recognising 'genuine concern' in parts of the community about exposure to PFAS and the potential health impacts, the panel stressed that risk communication must be 'tailored to the diverse levels of concern' and continued transparency maintained. The panel stated that reliable epidemiological studies required 'well characterised' exposures, measured confounders, and sufficiently large populations; conditions 'not currently met in the Blue Mountains population or in other communities in NSW'. It urged authorities to avoid using currently available human epidemiological studies to derive threshold levels due to the higher risk of bias and confounding. Instead, it supported continuing Australia's conservative approach of setting exposure limits based on animal studies with safety factors, such as those by the National Health and Medical Research Council. NSW chief health officer Kerry Chant said updated NSW Health advice provided consumers with guidance on how to reduce PFAS exposure. 'There is considerable concern, particularly in the Blue Mountains community, about exposure to PFAS through drinking water, and NSW Health takes these concerns very seriously,' Dr Chant said. 'NSW Health will continue to support local clinicians with information for GPs who may be managing patients with concerns about PFAS exposure, including evidence about potential adverse health effects, counselling patients, the utility of blood tests for PFAS and the role of further investigations.'

A beginner's guide to owning a pet in Australia

Microchipping and registration are both legal requirements for dog and cat owners. Make sure you do both as they are separate processes. A pet's healthcare plan includes regular check-ups, dental care, vaccinations, and treatment of any chronic conditions. Taking up the responsibility of an animal should be an informed decision by all household members involved in their care. Three years ago, Vindhya Nivunhellage and her partner, James, decided to welcome a dog into their lives. As a dog parent, she describes finding 'sheer joy' in the small things, like 'waking up and seeing a beaming face' or 'a wagging tail whenever you get home.' Melburnians James and Vindhya say they decided to become dog parents when their life conditions allowed to offer their pet the time and space it needed. Photo: Supplied 'And if there are days when you're feeling low, you still have an obligation to take your dog on a walk and… so you are forced to think beyond your own self.' But having a pet is also a commitment that shouldn't be taken lightly. 'Pets shouldn't be a Christmas present or a birthday gift. 'It should be something that is thought about fully with the whole family involved, and who does what, because you're bringing another individual into your household that requires constant attention.' Ms Nivunhellage shares the responsibilities of Algot's care with her partner. 'James and I, as we don't have children, we liken having Algot to having a baby because it requires so much planning. 'For example, for the first few years of Algot's life, we would take him to the dog park for a solid one hour of running in the morning and one hour of running in the evening. 'And we did that because we felt that we ought to give him that opportunity because he didn't have a backyard.' Especially if your residence doesn't have outdoors spaces, make sure your dog doesn't spend too much time alone or inactive during their day. Credit: FlyPet laws In Australia, there is legislation that regulates the keeping of dogs and cats. Tara Ward is the volunteer Managing solicitor at the Animal Defenders Office, a community legal centre for animal issues. She explains that while state and council pet laws differ, there are some legal requirements for cat and dog owners applying across the country. They include microchipping your pet. 'You can microchip other kinds of pets. That's an optional extra though. Cats and dogs, you have to do it. 'The vet or the person who inserts the microchip will record on the database information about who owns this animal and who to contact should the animal be lost,' Ms Ward explains. It is also mandatory for cat and dog keepers to register with their local authority. Ms Ward says a common misconception is that microchipping and registration are the same, but they're not. Microchipping involves 'a tiny chip the size of a grain of rice inserted in the neck or shoulders area of the dog or cat', explains Tara Ward from the Animal Defenders Office. Credit: FatCamera/Getty Images 'These are two entirely separate processes. Microchipping is about identifying your cat or your dog. Registering is about putting the details of your dog or your cat on your local government list of pets." When it comes to desexing pets, legislation varies from one jurisdiction to another. 'For example, when you get your cat or dog registered, it will cost more if the animal is not desexed, or they're going to require you to get a permit every year and pay a fee for that.' Check the laws that apply to your local council to ensure you comply with your legal responsibilities as a pet owner. 'The actual laws about dogs and cats are managed at the local council level. Do try to get across them, because you really want to avoid getting into legal issues about your animals,' says Ms Ward. Having your pet registered is the easiest way to establish you are their legal owner in situations where your animal is lost, or you don't possess it and want to get it back.

Professional training benefits include structured learning, targeted behaviour modification programs and socialisation through puppy schools. Nadia Peiris, senior animal care manager at RSPCA Victoria, shares some key advice for when choosing to be your dog's trainer: 'We always recommend positive reinforcement and positive-based training, using treats where possible. 'Make sure to start as early as possible, because the more that you can do in that critical early stage when they're puppies, the better. And just be consistent.' Some house plants can be toxic for animals when ingested. If you notice your cat chewing on plants, consider getting them some cat grass. Source: Moment RF /Things you should know about your pet: Worm and flee treatments are necessary both for pets kept indoors and outdoors. A dry nose is not uncommon in dogs nor an indication that they are unwell. Cats do not always land on their feet. A cat purring or a dog wagging their tail can be due to a range of moods, not necessarily feeling happy. Your pet's diet and health are responsibilities you need to factor in your care duties and your monthly budget. 'When it comes to food, the most important thing is that it's appropriate for that animal and for that life stage of the animal,' Dr Kate Golaszewski says, who is vet director of the Campbellfield site at Lort Smith animal hospital. And bear in mind that dogs and cats tend to get accustomed to the foods you feed them. 'Sometimes people will say 'oh, there's another brand of pet food that's on special, I'll try that this week'. But pets generally don't do terribly well with lots of changes in their diet and takes them a little while for their gut to respond,' Dr Golaszewski explains. Don't underestimate dental care when it comes to your pet's health, RSPCA's Nadia Peiris says. Credit: Capuski/Getty Images 'If you are transitioning to a different type of pet food, we recommend that you do it over about a week or so.' Feeding your pet human food is not advisable and, in some cases, can cause health issues. 'With chocolate, for example, we might see hyperactivity initially but that can then develop into maybe seizure activity. And the worst-case scenario, you can get dogs that present in a coma.' Beyond regular medical check-ups, animals with chronic conditions, like heart disease or skin problems, will require more frequent visits to the vet. Ultimately, just like with humans, Dr Golaszewski says any concerning changes in your pet's health should prompt a visit to the vet. If you notice anything unusual — like sudden lethargy or other abnormalities — it's best to get them checked. If uncertain about the local laws affecting your pet or dealing with a legal issue as a pet owner, you can reach out to the Animal Defenders Office for advice. If you find yourself in need of help to provide treatment and care to your pet or thinking of surrendering your pet, check the RSPCA website in your state/territory for information and available assistance programs.
