A routine drug screening using the CEDIA DAU assay falsely identified lysergic acid diethylamide (LSD) in urine samples from 12 intensive care unit patients. None of these positive results were confirmed by high-performance liquid chromatography, but all samples contained the mucolytic drug ambroxol. Further investigation showed that ambroxol significantly cross-reacts with the CEDIA DAU LSD assay. Positive LSD results from this assay require careful evaluation, especially during cold season when mucolytic medications are more commonly used.
A virtual 8-week mindfulness-based program (MORE) reduced daily pain intensity in people with lumbosacral radiculopathy (sciatica) compared with usual care, but did not improve disability, depression, or quality of life. Participants in the mindfulness group also reported greater increases in mindful reinterpretation of pain and trait mindfulness. The authors suggest that fear-avoidance behaviors may explain why pain relief did not translate into reduced disability in this long-duration chronic pain sample.
