Association of Opioid Use Disorder-Related Service Trajectories during Pregnancy and Postpartum Health Service Use: A Group-Based Multitrajectory Modeling Study.

Objective: The aim of the study was to examine the relationship between opioid use disorder (OUD)-related service trajectories during pregnancy and postpartum emergency department (ED) and hospitalizations.

Methods: We used the Merative MarketScan Commercial Claims and Encounters Database (2013-2021) to identify a cohort of pregnant individuals with OUD. We used group-based multitrajectory modeling to identify opioid-related treatment and service trajectories during pregnancy and examined their association with postpartum ED and hospital utilization.

Comparative Effectiveness of Buprenorphine Adherence with Telemedicine versus In-person for Rural and Urban Patients.

Background: Policy changes during the COVID-19 pandemic allowed buprenorphine to be prescribed for opioid use disorder (OUD) via telemedicine without an in-person visit. A recently proposed change will limit buprenorphine access to 30 days without an in-person visit. Given that people living in rural areas may be disproportionally impacted by this change, we sought to better understand how buprenorphine adherence may be impacted by requiring in-person visits.

Changes in Postpartum Opioid Prescribing After Implementation of State Opioid Prescribing Limits.

Importance: In response to the growing opioid crisis, states implemented opioid prescribing limits to reduce exposure to opioid analgesics. Research in other clinical contexts has found that these limits are relatively ineffective at changing opioid analgesic prescribing.

Objective: To examine the association of state-level opioid prescribing limits with opioid prescribing within the 30-day postpartum period, as disaggregated by type of delivery (vaginal vs cesarean) and opioid naivete.

Structure and selectivity of a glutamate-specific TAXI TRAP binding protein from Vibrio cholerae.

Tripartite ATP-independent periplasmic (TRAP) transporters are widespread in prokaryotes and are responsible for the transport of a variety of different ligands, primarily organic acids. TRAP transporters can be divided into two subclasses; DctP-type and TAXI type, which share the same overall architecture and substrate-binding protein requirement. DctP-type transporters are very well studied and have been shown to transport a range of compounds including dicarboxylates, keto acids, and sugar acids.

Opioid analgesic and antidepressant use during pregnancy and the risk of spontaneous preterm birth: A nested case-control study.

Background: Given the high prevalence of both mental health and acute pain conditions during pregnancy, use of antidepressants and analgesic opioids in this period is widespread. Whether single and combined use of these medications is associated with spontaneous preterm birth (sPTB) remains unclear.

Objectives: To investigate the association between maternal prescription opioid and antidepressant medication exposures for co-occurring mental health and acute pain management, either alone or in combination, and sPTB.
