Researchers have developed a noninvasive method to detect anemia using grayscale photos of the eye’s conjunctiva, taken with standard smartphones. By applying machine learning to spatial and textural features extracted from over 12,000 photos of 565 children aged 5 to 15, the study found strong associations between these features and anemia status. Unlike other approaches, this method does not rely on color analysis or specialized equipment, making it practical for use in low-resource settings. The findings suggest a scalable, affordable tool for anemia screening in children, especially in areas with limited access to laboratory testing.
The percentage of children under 18 years old with anxiety and depression increased steadily from 2016 to 2022, according to publicly available data from the National Survey of Children’s Health that were analyzed by researchers from Ann & Robert H. Lurie Children’s Hospital of Chicago. In contrast, there was no increase during that timeframe related to physical health problems, such as asthma, severe headache or migraine, and heart conditions. Results were published in JAMA Pediatrics.
A new study published in JAMA Internal Medicine found that hospitalized patients with alcohol use disorder who began taking the AUD medication naltrexone before they were discharged were able to reduce heavy drinking in the three-month period following their hospital stay. The findings specifically showed that both forms of naltrexone, which is offered as a pill or as an extended-release injectable, were similarly effective at reducing patients’ alcohol consumption. After three months of treatment, heavy drinking within the last 30 days decreased by approximately 38 percentage points among patients who took the oral version of naltrexone, compared to about a 46 percentage-point decrease among patients who received the injectable version of the medication.
