A recent preprint abstract discusses the development of a liver organoid-on-a-chip model for studying drug metabolism and transport. The model uses bioengineered hollow fiber membranes and adult human stem cell-derived organoids to create polarized and mature hepatocyte-like monolayers. These monolayers express a range of drug-metabolizing enzymes and transporters. The researchers also connected the liver organoid-on-a-chip model to small intestine and kidney proximal tubule-like systems to study drug bioavailability and excretion. This model has the potential to predict pharmacokinetic and ADME profiles in humans. However, it is important to note that this preprint has not yet undergone peer review.

A recent study conducted by researchers at the Naval Health Research Center in San Diego, California, examined outpatient prescriptions for insomnia medications during the first year following combat-related amputations. The study found that 78% of patients (1,291 out of 1,651) had prescriptions for insomnia medications, primarily anxiolytic sedative drugs. The prevalence of these prescriptions decreased over time, from 57% in the first quarter to 28% in the fourth quarter post-injury. Patient characteristics such as high Injury Severity Score, continued opioid and non-opioid analgesic prescriptions, and diagnoses of chronic pain, mood disorder, and posttraumatic stress disorder were associated with higher prevalence and duration of prescriptions. The study suggests that there is a need for more research on the treatment of insomnia during early post-injury rehabilitation among patients who sustained serious combat injuries.
