ChatGPT diagnoses ER patients ‘like a human doctor’: Study

The chatbot’s reasoning was “at times medically implausible or inconsistent, which can lead to misinformation or incorrect diagnosis, with significant implications,” the report noted.

The scientists also admitted some shortcomings with the research. The sample size was small, with 30 cases examined. In addition, only relatively simple cases were looked at, with patients presenting a single primary complaint.

It was not clear how well the chatbot would fare with more complex cases. “The efficacy of ChatGPT in providing multiple distinct diagnoses for patients with complex or rare diseases remains unverified.”

Imprisoned scientist who gene-edited babies wanted to transform the human species

The idea that genetic modification can improve humanity isn’t new, but it has taken some interesting turns within the scientific community over the past few years. One of the most notable comes from the mind of He Jiankui, a Chinese scientist whose gene editing of human babies led to infamy and a prison sentence. Now, He, known as JK to friends, thinks that gene-edited humans could be the future of our species.

Estimating life expectancy based on the age of type 2 diabetes diagnosis

Similarly, individuals who were diagnosed with diabetes at the age of 40 years died ten years earlier, and those diagnosed at the age of 50 died six years earlier than their healthy counterparts.

A robust association was established between earlier age of diabetes diagnosis and deaths due to vascular and non-neoplastic conditions. Common vascular diseases include stroke and myocardial infarction, while non-neoplastic conditions include neurological, respiratory, and infectious diseases.

The association between life expectancy and diabetes was marginally greater in women than in men. Compared to older adults, higher hazard ratios for mortality were associated with earlier age of diabetes detection.

Could your daily routine lead to dementia? New research points to sedentary lifestyle as potential risk factor

In a recent study published in JAMA, researchers investigated whether accelerometer-assessed sedentary behavior was associated with incident dementia.

The global population is engaging in more sedentary-type activities such as sitting while using the computer, watching television, and driving. Studies have reported associations between sedentary behavior and cardiometabolic diseases and related mortality; however, its relationship with new-onset dementia is not clear.

Ultrathin nanotech promises to help tackle antibiotic resistance

The innovation – which has undergone advanced pre-clinical trials – is effective against a broad range of drug-resistant bacterial cells, including ‘golden staph’, which are commonly referred to as superbugs.

Antibiotic resistance is a major global health threat, causing about 700,000 deaths annually, a figure which could rise to 10 million deaths a year by 2050 without the development of new antibacterial therapies.

The new study led by RMIT University and the University of South Australia (UniSA) tested black phosphorus-based nanotechnology as an advanced infection treatment and wound healing therapeutic.

Results published in Advanced Therapeutics show it effectively treated infections,… More.

Researchers have invented a nano-thin superbug-slaying material that could be integrated into wound dressings to prevent or heal bacterial infections.
