Kids Helpline has just launched a new mobile app for teenagers and young people with mental health issues. Called ‘niggle by Kids Helpline’, the new app aims to help young people identify any mental health concern or ‘niggle’. It has been designed to be used in conjunction with Kids Helpline’s existing services or as a stand-alone option for those people who may not have been willing or able to access help through traditional methods. The app provides, for free, hundreds of built-in resource and guided strategies that are all evidence-based.

In one of the more unusual studies seen in the medical journals of late, UK researchers have determined that some home cooked, family recipe broths actually have antimalarial properties. The study, published in the Archives of Diseases of Childhood, involved the testing of 56 samples of broths which had been made from recipes passed down as a tradition in families of diverse ethnic origin. These broths were believed to confer health benefits in times of illness, commonly helping to reduce fever. And before you start getting the mental image of these scientists deciphering these recipes and cooking up a storm, in fact these researchers asked school children at an ethnically-diverse UK primary school to simply bring in a sample of their family anti-fever soup. Of the 56 soup samples, five were found to significantly inhibit the growth of the asexual blood stage of Plasmodium falciparum in vitro. In fact, the inhibition seen with two of the broths was comparable to that seen with one of the leading antimalarial agents, dihydroartemisinin

If you’re going through IVF, you may be offered a test to look at your embryos’ chromosomes. Pre-implantation genetic testing for aneuploidy (chromosome abnormalities), known as PGT-A, is an “add on” used to help choose embryos with the right number of chromosomes. It’s promoted by IVF clinics as a way to increase the chance of success, especially for women over 35. But the evidence shows that in most cases, PGT-A doesn’t improve the chance of a baby. What is aneuploidy? Human cells usually contain 46 chromosomes. Aneuploidy is a term that describes a chromosome number that is different from 46 – either too many or too few chromosomes. In human embryos, most aneuploidies are lethal, resulting in miscarriage, or do not result in pregnancy at all. The chance of aneuploidy increases with the age of the woman; by the time a woman reaches age 40, approximately 80% of her embryos are aneuploid.

Prominent GP and former member of parliament Kerryn Phelps has entered the turf war between doctors and pharmacists over who gets to prescribe. Pharmacy groups have long called for changes to allow pharmacists to prescribe specified medications, such as the oral contraceptive pill and antibiotics for urinary tract infections. But Phelps argues allowing pharmacists to prescribe will lead to perverse incentives – where pharmacists prescribe inappropriately – because they have a financial interest in the sale of medicines. Phelps has a point. Studies in countries where doctors have dispensing roles have found evidence of financial profits influencing prescribing behaviour. A Swiss study, for instance, found physician dispensing leads to a 34% increase in drug costs per patient, as doctors overprescribe and prescribe more expensive medications.

Low lymphocyte levels can used as an indicator of an increased risk of mortality, US researchers say. Lymphopaenia, readily measured through the common full blood count, has been shown to be associated with an increased likelihood of death from conditions such as heart disease, cancer and respiratory infections, according to a retrospective study published in JAMA Network Open. This relationship was found to be consistent, independent of age, other serum immune markers and traditional clinical risk factors. However, when patients with lymphopaenia also had other abnormal immune markers, namely elevated red cell distribution width (RDW) and a raised C-reactive protein (CRP), they ‘had a strikingly high risk of mortality’, the study authors said.

It takes a supreme effort of will to overcome an addiction, but even more so to avoid relapse. The effect of relapse can hugely effect quality of life or even prove fatal. To help give recovering addicts a fighting chance, researchers at University of Washington have been studying whether changing the activity of neurons in the nucleus accumbens, the region of the brain that regulates addictive behaviour, can help to prevent relapse. They achieved this targeted change in brain activity using chemogenetic receptors in a study conducted on rats who had been exposed to heroin.

Western Australia is on the brink of becoming the second state in Australia to legalise voluntary assisted dying, with its upper house last night passing the Voluntary Assisted Dying Bill 2019 (WA). A total of 55 amendments to the initial version of the bill were passed. The bill will return to the lower house next week to review the amendments. If these amendments are ratified as expected, WA will follow the historic introduction of voluntary assisted dying in Victoria, where the option has been available since June 2019.

Drinking patterns tend to change as we age. The older we get, the more likely we are to drink on a daily basis. But older adults often perceive that drinking is only a problem if a person appears drunk.

“Breast implants are not lifelong devices,” says plastic surgeon, Professor Rodney Cooter. Even with the most advanced version of these implants put in by the most experienced surgeons, there is likely to be deterioration over time and patients should be warned of this potential and regularly monitored.

There appears to be a myriad of potential treatments for our current health threat – COVID19. But just how real are these options? And which if any of these are likely to make it into our treatment regimens? A review just published online in JAMA gives us a neat summary of where we are up to in terms of treatment.
