First Smartphone DNA Test for Chlamydia to Be Presented at 2015 AACC Annual Meeting

PR Newswire July 29, 2015

At the 2015 AACC Annual Meeting & Clinical Lab Expo, researchers will present findings that a first-of-its-kind smartphone test for chlamydia can detect the disease with high accuracy, which could reduce the prevalence of this sexually transmitted disease (STD) by making chlamydia screening easier and cheaper.
Most people with chlamydia are not aware of it because the infection often causes no symptoms, but if left untreated, this STD can develop into pelvic inflammatory disease and irreversibly damage a woman’s reproductive system. According to the Centers for Disease Control and Prevention, pelvic inflammatory disease affects up to 30% of women with chlamydia, and can cause infertility; debilitating, chronic pelvic pain; and life-threatening ectopic pregnancies. Over the past decade, healthcare providers have been able to expand screening programs for chlamydia thanks to the development of a highly sensitive method known as nucleic acid amplification testing (NAAT). NAATs are too complex, however, to perform in point-of-care settings such as physicians’ offices, health fairs, school clinics, or other sexual health outreach venues, and they also have a high per-test cost.

Prostate cancer: Five types ‘found’

BBC News 30 July 2015

Scientists have identified five types of prostate cancer, each with a distinct genetic signature.
And by comparing 250 samples removed in surgery with the patients’ subsequent progress, they have identified some types that are more likely to recur.
Until now, there has been no reliable way to know which patients have the more aggressive cancers requiring the most urgent and intensive therapy.
But much larger trials are still needed to be certain of these early results.

Skin cancer survival rates higher for females than males, says Cancer Council

The Courier Mail ROSE BRENNAN July 30, 2015

WOMEN who have had children are more likely to beat skin cancer than women who don’t, with new research showing that all women have better survival rates than men.
Research from Cancer Council Queensland, to be released today, found survival rates were higher for females than males for nearly all ­tumour stages but the advantage was weaker for women aged under 45.
“Our research shows the survival differences for women aren’t just present with thick melanoma, but also stage one melanoma – the most commonly diagnosed,” spokeswoman Katie Clift said.

Instant blood test devices to cut down medical evacuation costs

ABC News 27 July 2015

People in remote areas may not need to be medically evacuated or travel for medical testing and treatment following research into on-site pathology-testing.   Flinders University has been given a $95,000 Emergency Medicine Foundation (EMF) grant to research the benefit of the point-of-care testing (POCT) program in six remote Northern Territory communities.

Diabetics at greater risk of TB: study

Brisbane Times AAP 27 July 2015

A 20-year James Cook University study has found the weakened immune systems of diabetics make them more vulnerable to tuberculosis.

“If you suffer from diabetes and your immune system is not functioning well, it can flare up,” Director of Microbiology at Townsville Hospital, Dr Robert Norton, said.

All diabetes sufferers should therefore be screened for tuberculosis, he said.

Committal proceedings start over murder of Sophie Collombet

Courier Mail Kate Kyriocou, Rhian Deutrom 27 July 2015

DEFENCE lawyer Michael Bosscher has consented to his client Benjamin Milward being sent to the Supreme Court for trial for the murder of French student Sophie Collombet, whose body was found in a Brisbane park in March 2014.

It comes after a forensic scientist said DNA taken from under the fingernails of murder victim Ms Collombet was likely to have come from Milward.

Amanda Reeves, a forensic scientist at Queensland’s John Tonge Centre, said she analysed a “tape lift” taken from Ms Collombet’s hand.

She also analysed DNA taken from underneath the fingernails of her right hand, agreeing that the DNA was 1.1 million times more likely to have come from Milward than not.

The samples were also compared to DNA from David Nelson and Lane Smith — witnesses who took the stand earlier this morning.

Two of those results were inconclusive because of a low number of DNA comparison points — or a lack of information.

Ms Reeves agreed the DNA comparison results had to be recalculated because of a “miscode” with the software.

“So it was wrong,” Mr Bosscher said.

Ms Reeves said she could not say it was wrong but agreed it had to be redone.
