RESUMO
In 2021, an 8-mg intranasal naloxone product was approved by the Food and Drug Administration; however, no studies have examined outcomes among persons who receive the 8-mg naloxone product and those who receive the usual 4-mg product. During March 2022-August 2023, New York State Department of Health (NYSDOH) supplied some New York State Police (NYSP) troops with 8-mg intranasal naloxone; other troops continued to receive 4-mg intranasal naloxone to treat suspected opioid overdose. NYSP submitted detailed reports to NYSDOH when naloxone was administered. No significant differences were observed in survival, mean number of naloxone doses administered, prevalence of most postnaloxone signs and symptoms, postnaloxone anger or combativeness, or hospital transport refusal among 4-mg and 8-mg intranasal naloxone recipients; however, persons who received the 8-mg intranasal naloxone product had 2.51 times the risk for opioid withdrawal signs and symptoms, including vomiting, than did those who received the 4-mg intranasal naloxone product (95% CI = 1.51-4.18). This initial study suggests no benefits to law enforcement administration of higher-dose naloxone were identified; more research is needed to guide public health agencies in considering whether 8-mg intranasal naloxone confers additional benefits for community organizations.

INTRODUCTION: Telemedicine is a feasible alternative to in-person evaluations for people with opioid use disorder (OUD). The literature on medications for opioid use disorder (MOUD) telemedicine has focused on ongoing OUD treatment. Emergency department (ED) visits are an opportunity to initiate MOUD; however, little is known regarding the outcomes of patients following telemedicine referrals for MOUD from emergency settings. The current study describes rates of initial outpatient clinic appointment attendance and 30-day retention in care among patients referred by telemedicine compared to ED referrals. METHODS: This paper reports a retrospective review of data for patients referred from EDs or telemedicine through the Medication for Addiction Treatment and Electronic Referrals (MATTERS) Network. The MATTERS online platform collects data on patient demographic information (e.g., age, gender, race/ethnicity, and insurance type), reason for visit, prior medical and mental health history, prior OUD treatment history, and past 30-day substance use behaviors. Analyses compared initial visit attendance and 30-day retention among the patients for whom follow-up data were received from clinics by demographic and initial treatment factors. RESULTS: Between October 2020 and September 2022, the MATTERS Network made 1349 referrals; 39.7 % originated from an ED and 47.8 % originated from telemedicine. For patients with available data, those referred from telemedicine were 1.64 times more likely to attend their initial clinic appointment and 2.59 times more likely be engaged in treatment at 30 days compared to those referred from an ED. More than two-thirds of patients referred from the emergency telemedicine environment followed up at their first clinic visit and more than half of these patients were still retained in treatment 30 days after referral. CONCLUSIONS: The rates of initial clinic visit and 30-day retention when referred following a telemedicine evaluation are encouraging. Further development of telemedicine programs that offer evaluations, access to medications, and referrals to treatment should be considered.
RESUMO
Schwann cell tumors are the most common cancers of the peripheral nervous system and can arise in patients with neurofibromatosis type-1 (NF-1) or neurofibromatosis type-2 (NF-2). Functional interactions between NF1 and NF2 and broader mechanisms underlying malignant transformation of the Schwann lineage are unclear. Here we integrate bulk and single-cell genomics, biochemistry, and pharmacology across human samples, cell lines, and mouse allografts to identify cellular de-differentiation mechanisms driving malignant transformation and treatment resistance. We find DNA methylation groups of Schwann cell tumors can be distinguished by differentiation programs that correlate with response to the MEK inhibitor selumetinib. Functional genomic screening in NF1-mutant tumor cells reveals NF2 loss and PAK activation underlie selumetinib resistance, and we find that concurrent MEK and PAK inhibition is effective in vivo. These data support a de-differentiation paradigm underlying malignant transformation and treatment resistance of Schwann cell tumors and elucidate a functional link between NF1 and NF2.
