CONTEXT: The United States is in the midst of an opioid overdose epidemic. Opioids killed more than 28 000 people in 2014, more than any year on record. One approach to addressing this growing epidemic is Opioid Overdose Education and Naloxone Distribution (OEND) training. Little is known about these programs' participants and their effectiveness across different demographic groups. OBJECTIVES: To examine (1) whether knowledge and attitudes improved over the course of the training programs; (2) whether training outcomes differ by demographics; and (3) what overdose experiences do attendees have, and whether those experiences influence their knowledge and attitudes. DESIGN: A pre- and posttest survey was used to collect data on participants' demographics, overdose experiences, and opioid overdose knowledge and attitudes. SETTING: Surveys that took place at community-wide OEND programs were offered throughout Erie County, New York, during October and November 2015. PARTICIPANTS: Community members who elected to attend the training programs, were at least 18 years of age, spoke English, and were willing and able to participate were included in the sample (N = 198). INTERVENTION: N/A. MAIN OUTCOME MEASURE: The Opioid Overdose Knowledge and Attitudes Scale. RESULTS: Knowledge and attitude scores significantly improved from pre- to posttest assessments, increasing by 23.1% and 15.4%, respectively (Ps < .001). There were significant demographic differences in knowledge and attitudes at the pretest assessment, but these differences were ameliorated by the OEND program and did not persist at posttest assessment. In addition, 62.9% of participants had never experienced, witnessed, or known someone who had overdosed. CONCLUSION: Results indicate that OEND programs are effective at improving knowledge and attitudes toward opioid overdose. These results indicate that OEND programs are not reaching the highest risk individuals but are instead attracting concerned family and significant others. Future programs should focus on reaching current opioid users, overdose victims, and their families to ensure OEND programs are reaching the target audiences.

Background: As overdose remains a major public health concern in the United States, it is important to understand the experiences people who inject drugs (PWID) have with overdose. Past experiences during such emergencies are an important determinant of future behavior, including help seeking, which can be lifesaving. Methods: We explored experiences with overdose, using data from 21 in-depth interviews collected from PWID in a rural county in West Virginia (Cabell County). We used an iterative, modified constant comparison approach to synthesize resulting interview data. Results: Participants reported pervasive experiences with overdose, including through their own personal overdose experiences, witnessing others overdose, and losing loved ones to overdose fatalities. Experiencing emotional distress when witnessing an overdose was common among our participants. Many participants reported regularly carrying naloxone and using it to reverse overdoses. Multiple participants described believing the myth that people grow immune to naloxone over time. Concerns about the presence of fentanyl in drugs were also common, with many participants attributing their own and others' overdoses to fentanyl. Conclusions: Our findings have important implications for naloxone access and education, as well as policies and practices to encourage help seeking during overdose events among rural PWID. Participant concerns about fentanyl in the drug supply highlight the need for access to drug checking technologies.

The growing demand for healthcare services highlights the need for diverse, well-trained healthcare professionals beyond physicians. To address the forecasted shortage of U.S. physicians, healthcare systems increasingly rely on allied health professionals, including nurse anesthetists, physician assistants, and various other specialists, such as pharmacists, psychologists, occupational therapists, and physical therapists. These professionals require training in Graduate Allied Health Education (GAHE) programs, yet there is limited guidance for structuring these programs alongside traditional Graduate Medical Education (GME). This article discusses a comprehensive model for integrating GME and GAHE oversight at the institutional level, exemplified by San Antonio Uniformed Services Health Education Consortium (SAUSHEC). Key elements include policy alignment, accreditation considerations, resource allocation, and interprofessional training. Through SAUSHEC's parallel oversight committees for GME and GAHE, we demonstrate how structured integration enhances training and patient outcomes, benefiting trainees, healthcare team members, and patients. Our model promotes an inclusive, interprofessional environment where allied health professionals and physicians train collaboratively, ultimately improving patient care quality and institutional efficiency.

Unique from other fetal anatomical systems, the central nervous system (CNS) starts development early in the embryonic period shortly after fertilization before most patients are even aware they are pregnant. Maturation throughout pregnancy involve complicated structural and functional changes, most likely below the resolution of testing to detect. During this time, the fetal CNS is susceptible to lesions that reflect trimester-specific adverse events. Neonatal neurological status with childhood sequelae can result from combinations of antenatal, peripartum and neonatal adverse events. Person-specific clinical management choices must consider the timing of multiple mechanisms that can alter neurodevelopment including genetic causes, aetiologies after conception as well as communicable and non-communicable conditions that result in anomalous or destructive brain lesions. The appearance of the fetal brain also changes significantly through gestation as different structures mature and the cerebral cortex in particular increases in size and complexity. Therefore, obstetrical imagers and maternal fetal medicine physicians need to be aware of the expected evolving appearances of the healthy fetal brain as the fetus advances in gestation. Often when fetal CNS pathology is detected or anticipated during pregnancy, there is understandably significant parental anxiety regarding the long-term implications of their child's neurodevelopmental prognosis. In these instances, Maternal Fetal Medicine specialists often collaborate with Pediatric Neurologists in the antenatal period regarding diagnoses that anticipate neonatal or later childhood neurologic sequelae. Potential adverse outcomes are discussed with prospective parents to be integrated into choices based on shared decisions.

The leaves of Mitragyna speciosa (kratom), a plant native to Southeast Asia, are increasingly used as a pain reliever and for attenuation of opioid withdrawal symptoms. Using the tools of natural products chemistry, chemical synthesis, and pharmacology, we provide a detailed in vitro and in vivo pharmacological characterization of the alkaloids in kratom. We report that metabolism of kratom's major alkaloid, mitragynine, in mice leads to formation of (a) a potent mu opioid receptor agonist antinociceptive agent, 7-hydroxymitragynine, through a CYP3A-mediated pathway, which exhibits reinforcing properties, inhibition of gastrointestinal (GI) transit and reduced hyperlocomotion, (b) a multifunctional mu agonist/delta-kappa antagonist, mitragynine pseudoindoxyl, through a CYP3A-mediated skeletal rearrangement, displaying reduced hyperlocomotion, inhibition of GI transit and reinforcing properties, and (c) a potentially toxic metabolite, 3-dehydromitragynine, through a non-CYP oxidation pathway. Our results indicate that the oxidative metabolism of the mitragynine template beyond 7-hydroxymitragynine may have implications in its overall pharmacology in vivo.
