Kyoto, Japan -- Opioids like morphine are widely used in medical practice due to their powerful pain-relieving effects. However, they carry the risk of serious adverse effects such as respiratory depression and drug dependence. For this reason, Japan has strict regulations in place to ensure that these medications are prescribed only by authorized physicians.

In the United States, however, the opioid OxyContin was once prescribed frequently triggering a surge in the misuse of synthetic opioids such as fentanyl. As a result, the number of deaths caused by opioid overdose surpassed 80,000 in 2023, escalating into a national public health crisis now referred to as the "opioid crisis".

Opioids may soon have a rival, however. A team of researchers at Kyoto University has recently discovered a novel analgesic, or pain reliever, which exerts its effect through an entirely different mechanism. Clinical development of their drug ADRIANA is currently underway as part of an international collaborative effort.

The stress premature infants experience at birth can carry on throughout a lifetime and cause negative health impacts later in life, necessitating the routine inclusion of birth history in medical records and the development of clinical guidelines for adults born preterm, the longest continuously running study of individuals born preterm in the United States has shown. University of Rhode Island College of Nursing Professor Amy D’Agata is continuing the work that began in the 1980s with a group of babies born prematurely at Women & Infants Hospital.
