Abstract

fetched live from OpenAlex

ABSTRACT Introduction: Medications to treat opioid use disorder (MOUD) has been associated with improved maternal-fetal outcomes when compared with illicit opioid use during pregnancy. However, there remains ambiguity surrounding optimal strategies for initiating and rotating MOUD for pregnant patients. This manuscript aims to introduce a novel approach to rotating a patient from methadone to sublingual buprenorphine/naloxone during pregnancy, followed by a rapid macrodosing titration to depot buprenorphine in the immediate postpartum period. Methods: This is a case report. It follows one patient’s experience with illicit opioid use and MOUD in the peripartum period. Results: While the patient completed an uncomplicated intrapartum in-hospital rotation from methadone to sublingual buprenorphine/naloxone at 26 weeks gestation, she discontinued MOUD and resumed illicit opioid use 1 week later. The patient successfully completed a macroinduction of depot buprenorphine immediately postpartum and has since remained adherent to monthly depot injections and abstinent from illicit opioids for 5 months and counting. Conclusions: This manuscript details a unique and effective approach to a rotation of a pregnant patient from methadone to sublingual buprenorphine/naloxone via low-dose initiation, plus rapidly initiating depot buprenorphine immediately postpartum via macrodosing. Details of these protocols may aid future obstetrical addiction providers in optimizing opioid management for their patients. Introduction: Médicaments pour traiter les troubles liés à la consummation d’opiacés a été associé à une amélioration des résultats maternels-fœtaux par rapport à la consommation d’opioïdes illicites pendant la grossesse. Cependant, l’ambiguïté demeure quant aux stratégies optimales d’instauration et de rotation du médicaments pour traiter les troubles liés à la consummation d’opiacés chez les patientes enceintes. Ce manuscrit vise à présenter une nouvelle approche pour faire passer une patiente de la méthadone à la buprénorphine/naloxone sublinguale pendant la grossesse, suivie d’une titration rapide par macrodosage à la buprénorphine par dépôt dans la période post-partum immédiate. Méthodes: Il s’agit d’un rapport de cas. Il retrace l’expérience d’une patiente qui a fait usage d’opioïdes illicites et de son médicaments pour traiter les troubles liés à la consummation d’opiacés pendant la période péri-partum. Résultats: Bien que la patiente ait effectué une rotation intra-partum sans complication de la méthadone à la buprénorphine sublinguale/naloxone à la 26e semaine de gestation, elle a interrompu le médicaments pour traiter les troubles liés à la consummation d’opiacés et repris l’usage d’opioïdes illicites une semaine plus tard. La patiente a réussi une macro-induction de buprénorphine par dépôt immédiatement après l’accouchement et est restée depuis lors fidèle aux injections mensuelles par dépôt en s’abstenant de consommer des opioïdes illicites depuis maintenant cinq mois. Conclusions: Ce manuscrit décrit une approche unique et efficace pour faire passer une patiente enceinte de la méthadone à la buprénorphine/naloxone sublinguale par initiation à faible dose, en plus de l’initier rapidement à la buprénorphine par dépôt immédiatement après l’accouchement par macrodosage. Les détails de ces protocoles peuvent aider les futurs prestataires de soins obstétriques aux toxicomanes à optimiser la gestion des opioïdes pour leurs patientes.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
