Researchers report a significant advance in the search for medications that can suppress pain but avoid opioids’ abuse potential and other undesirable CNS effects. A new compound reduces mouse responses in animal models of neurogenic and chronic inflammatory (e.g., arthritic) pain. The compound, called UB937, enhances the natural pain-killing activity of the neurotransmitter anandamide, and exerts its analgesic effects entirely in peripheral tissues, without entering the brain.
Men benefit more than women from nicotine replacement therapy for smoking cessation because nicotine affects a key neuroreceptor differently in the two sexes, a NIDA-sponsored study suggests. The findings highlight the need for alternative therapies for women smokers, and point to the female hormone progesterone as a potential therapeutic target.
Several factors contribute to treatment professionals’ stress and burnout, including how much influence they feel they have in their organization and their caseload. Surprisingly, a NIDA-supported study found that the link between staff stress and burnout was weaker in programs with higher patient caseloads than those with lower caseloads. In addition, program administrators can help counselors reduce their stress by giving them a voice in organizational policies and procedures.
