Artificial intelligence in healthcare: not always fair
Machine learning and AI are playing an increasingly important role in medicine and healthcare, and not just since ChatGPT. This is especially true in data-intensive specialties such as radiology, pathology or intensive care. The quality of diagnostics and decision-making via AI, however, does not only depend on a sophisticated algorithm but – crucially – on the quality of the training data.

AI system could help detect patients’ pain before, during and after surgery
An automated pain recognition system using artificial intelligence (AI) holds promise as an unbiased method to detect pain in patients before, during and after surgery.

Baby on-screen 24/7
True or false: Webcams have only recently been introduced in neonatology and are a patient-side component of the Digital Health Portfolio. False! Already in 1989, Professor Dr Roland Wauer at Charité Berlin built his DIY system to transmit images from the neonatology ward.

Sensitive women, stoical men? How gender stereotypes sabotage medical pain treatment
Stereotypical gender notions can affect how healthcare staff treat people in pain. This, in turn, may result in medically unjustified disparities in treatment of men and women, or “gender bias.”

Facial analysis algorithm to track Parkinson’s Disease
Parkinson’s disease (PD) usually causes facial abnormalities that affect a person’s self-esteem and relationships. However, these abnormalities are difficult to analyze quantitatively with current methods. To address this issue, scientists from Okayama University, Japan, explored whether commercial AI-based facial analysis software could be useful in this context. Their results show that…

AI uses ‘selfies’ to detect heart disease
Sending a “selfie” to the doctor could be a cheap and simple way of detecting heart disease, according to the authors of a new study. The study is the first to show that it’s possible to use a deep learning computer algorithm to detect coronary artery disease (CAD) by analysing four photographs of a person’s face. Although the algorithm needs to be developed further and tested in larger…

'Uncanny Valley': Brain network evaluates robot likeability
Scientists have identified mechanisms in the human brain that could help explain the phenomenon of the 'Uncanny Valley' - the unsettling feeling we get from robots and virtual agents that are too human-like. They have also shown that some people respond more adversely to human-like agents than others.

Training a computer to classify breast cancer tumors
Using technology similar to the type that powers facial and speech recognition on a smartphone, researchers at the University of North Carolina Lineberger Comprehensive Cancer Center have trained a computer to analyze breast cancer images and then classify the tumors with high accuracy. In a study published in the journal NPJ Breast Cancer, researchers reported they used a form of artificial…

An unusual 'friend' to help fight ovarian cancer
In some cases, the Lassa virus starts with a fever and general weakness, moving toward headache, muscle pain, possible facial swelling, deafness, and worse. About 15 percent of patients hospitalized with severe cases die. Lassa fever is contagious, endemic in West Africa, and Dr. Anthony van den Pol thinks he can use it to cure ovarian cancer.

Speeding identification of deadly bacteria
A new way of rapidly identifying bacteria, which requires a slight modification to a simple microscope, may change the way doctors approach treatment for patients who develop potentially deadly infections and may also help the food industry screen against contamination with harmful pathogens, according to researchers at the Korea Advanced Institute of Science and Technology (KAIST) in Daejeon,…
Mindray’s support helps Operation Smile repair facial deformities
Ever mindful of those less fortunate, Mindray Medical International continues to support the children’s medical charity, Operation Smile. Each year Mindray sponsors the global organisation to be a part of Mindray’s exhibit at the American Society of Anaesthesiology (ASA) meeting.
Integrated 3-D Imaging Facilitates Human Face Transplantation
By combining conventional medical imaging with some of the same 3-D modeling techniques used in Hollywood blockbusters, researchers are offering new hope to victims of serious facial injuries. Results of a new study on human face transplantation, led by Darren M. Smith, M.D., plastic surgery resident at the University of Pittsburgh Medical Center (UPMC), were presented today at the annual meeting…
How can we measure infants' pain after an operation?
It turns out to be difficult to find out exactly how much a child who cannot yet speak suffers after a surgical operation. Researchers at the University Hospital of La Paz, in Madrid, have validated the 'Llanto' scale, the first, and only, tool in Spanish which measures infant pain rapidly and simply.
PET scanning the heart cuts costs
USA - Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves money, according to researchers reporting at the American College of Cardiology's Annual Scientific Session in March.
