Cure for Asthma?

Queensland researchers have done it again with a new discovery on a possible cure for asthma. Human trials begin in July so if you live in Brisbane and are aged between 18 and 65 and have the condition you might like to give them a call on 1800 257 179. Or email them - just check out the link.

New Smartphone app for cough

The University of Queensland is developing a new smartphone app that will help doctors and patients alike with cough diagnosis and treatment. It could potentially save lives in conditions such as pneumonia and whooping cough. Conversely it may help reduce the use of unnecessary antibiotics for more benign conditions. The company has been listed on the stock market too and the app is due out in 2016.

Malaria vaccine for Africa

GSK has developed a vaccine against malaria that has been approved for rolling out in Africa. Sounds good but I don't think the search is over as it is only 27-46% effective. Come on scientists, you can do better!

Progress in India

Heartening news for global health watchers from Reuters article about the latest studies on health improvements in India. There has been positive movements in number of breastfed infants, number of births in hospitals, and improvements in child nutrition. The rate of child marriage is still high and adolescent girls are still low in body mass, but signs are improving. Female health workers from within the community called Ashas are trained in pre- and post-natal care and are a bonus!

More Weighty News

Monash researchers have been working away on weighty matters. They have found some interesting neurons that help switch off hunger. However the new insights are unlikely to help people lose weight as eating is fuelled by many social and emotional signals in humans. Researchers do hope that they may be able to help with weight maintenance, though.

And Google is developing a great new app that calculates calories in food from a photo of the food. I could use that!

Treatment for Alzheimers

An article from Science Direct informs us that a new treatment for Alzheimers involving non-invasive ultrasound to target the toxic amyloid plaques and neuro-fibrillary tangles that are pathognomonic of the disease has been developed by the Queensland Brain Institute. The research has so far involved mice and the next step is to test the method on sheep before ascertaining whether the technology can be used on humans.

The Queensland Brain Institute is at the forefront of research on Alzheimer's, Parkinson's and Motor Neuron Disease. Here is the podcast.

On a more topical note is the neuroscience behind the film Inside Out. Read about it here.

More on Needle-free Immunisations

Professor Mark Kendall has delivered a most engaging TED talk where he describes the history of needles and the latest development in his research.  With improved immune responses to the nanopatch, vaccines that were previously too expensive to administer in the developing world can now be available at a hundredth of the dose to those in particular need.  This same logic applies to vaccine candidates that are currently too weak to be effective.  Examples include vaccines currently under development against HIV, tuberculosis and malaria.  Improved immune responses with the nanopatch delivery method allows for a better way to tackle these diseases.

Another advantage of the nanopatch delivery method is it eliminates the need for the "cold chain" - that is the need for current liquid preparation vaccines to be refrigerated from the point of manufacture to the point of administration.  This cold chain has to be maintained throughout the vaccines' journey and is a key limitation in the developing world, where temperatures are high and fridges are few.  Up to 50% of vaccines in Africa are ineffective due to failure of the cold chain.  With the nanopatch this requirement is removed as the vaccine is a dry preparation.

Currently there are field trials of the HPV vaccine (cervical cancer vaccine) in Papua New Guinea.  This trial tests two of the limitations of current vaccines - the cold chain and the prohibitive cost.  I will be following the results with interest.

Not to mention - no more needle-phobia!
