Background: Little attention has been paid to the experiences of clinicians and health personnel who provide heroin-assisted treatment (HAT). This study provides the first empirical findings about the clinicians' experiences of providing HAT in the Norwegian context.

Methods: 23 qualitative interviews were conducted with 31 clinicians shortly after HAT clinics opened in Norway's two largest cities: Oslo and Bergen.

Background/objective: Adequate postoperative analgesics are an essential element in the recovery and rehabilitation of large joint lower-limb arthroplasty patients in their acute postoperative phase. In this study, we will establish that strong opioids like morphine should be included as postoperative analgesics to improve patient satisfaction.  Material: This retrospective cross-sectional study was conducted in the Arthroplasty Ward, Trauma, and Orthopaedics Department in a district general hospital of the United Kingdom.

Drug addiction is a multifactorial syndrome in which genetic predispositions and exposure to environmental stressors constitute major risk factors for the early onset, escalation, and relapse of addictive behaviors. While it is well known that stress plays a key role in drug addiction, the genetic factors that make certain individuals particularly sensitive to stress and, thereby, more vulnerable to becoming addicted are unknown. In an effort to test a complex set of gene x environment interactions-specifically gene x chronic stress-here we leveraged a systems genetics resource: BXD recombinant inbred mice (BXD5, BXD8, BXD14, BXD22, BXD29, and BXD32) and their parental mouse lines, C57BL/6J and DBA/2J.

Article Synopsis
  • Intraoperative neuromonitoring (IONM) is essential for ensuring patient safety during scoliosis surgery by monitoring spinal cord and nerve function through motor-evoked potentials (MEPs), with anesthesia type affecting the accuracy of these signals.
  • A systematic review was carried out, analyzing studies from major medical databases, which evaluated the impact of various anesthetic techniques on neuromonitoring during scoliosis procedures, narrowing down from 998 articles to 45 for detailed analysis.
  • The findings suggest that the Erector Spinae Plane Block (ESPB) offers significant advantages over traditional spinal and epidural anesthesia by improving neuromonitoring accuracy, reducing complications, and providing effective pain management, leading to better patient outcomes.

Orvinol-based opioid receptor antagonist fluorinated at C(20)-pharmacophore.

Eur J Med Chem

December 2024

A. N. Nesmeyanov Institute of Organoelement Compounds, Russian Academy of Sciences, ul. Vavilova 28, bld. 1, Moscow, 119334, Russia. Electronic address:

Thevinols and their 3-O-demethylated relatives, orvinols, are derivatives of the Diels-Alder adduct of natural alkaloid thebaine with methyl vinyl ketone. Taken together, thevinols and orvinols constitute an important family of opioid receptor (OR) ligands playing an important role in both the OR mediated antinociception and OR antagonism. Herein, we disclose for the first time the antagonist activity of the N-allyl substituted orvinol derivative fluorinated within the pharmacophore associated with C(20) and its surrounding.
