Observational Study
Analysis of Nausea and Vomiting Frequency Following Opioid Dose Escalation and Its Risk Factors: A Single-Center Retrospective Observational Study.
Background and Objective: Opioid-induced nausea and vomiting (OINV) is known to develop not only upon opioid introduction but also during opioid dose escalation, but the actual details are unclear. The aim of this study was to investigate the frequency of OINV in opioid dose escalation at a single center and to identify risk factors. Methods: A retrospective analysis of the medical records of hospitalized patients with cancer who underwent increased intake of oral oxycodone extended-release tablets at Komaki City Hospital between January 2016 and December 2019 was performed. ⋯ Performance status (≥2) (odds ratio [OR]: 2.36, 95% confidence interval [95% CI]: 1.15-4.84, p = 0.02) and history of nausea for opioid introduction (OR: 2.92, 95% CI: 1.20-7.10, p = 0.02) were detected as risk factors for the development of OINV. Conclusion: This study revealed a high incidence of OINV during opioid dose escalation, indicating that careful monitoring is required as at the time of opioid introduction. Further validation by a prospective study is required.

The current study aimed to evaluate anxiety behavior, hippocampal ionized calcium-binding adaptor molecule 1 (Iba1) and cannabinoid receptor 1 (CB1) gene expression, and nociceptive response in adulthood after a combination of fentanyl and cannabidiol (CBD) for nociceptive stimuli induced during the first week of life in rats. Complete Freund's adjuvant-induced inflammatory nociceptive insult on postnatal day (PN) 1 and PN3. Both fentanyl and CBD were used alone or in combination from PN1 to PN7. ⋯ Moreover, the expression of Iba1 varied according to the administered dose of CBD and may or may not be associated with the opioid. A lower dose of CBD during the inflammatory period was associated with enhanced anxiety in adult life. PERSPECTIVE: The treatment of nociceptive stimuli with CBD and opioids during the first week of life demonstrated significant sex differences in adult life on anxiety behavior and supraspinal pain sensitivity.

A preclinical study in animals has further characterised a new 'arousal' agent. Danavorexton (TAK-925) is an agonist for orexin receptor 2 where it promotes recovery from inhalational and i.v. anaesthesia and opioid sedation. Although danavorexton reverses opioid sedation, it does not compromise analgesia. This could be a useful addition to the postoperative drug cupboard.

Inclusion of Sex and Gender Differences in U.S. State Action Plans for Opioid Use and Opioid Use Disorder.
Background: States have developed action plans to address the "opioid crisis" over the past several years. While sex- and gender-based differences have been identified in complications of opioid use, risks of addiction to opioids, barriers to treatment of opioid use disorder, and associated stigma, it is unknown if or to what extent opioid plans consider or account for these differences. The objectives of this study were to analyze U. ⋯ Two states included more than half of the variables and five plans made no mention of sex or gender differences. Conclusions: Few state plans contained sex- or gender-specific information, and those that did focused almost exclusively on childbearing, excluding other unique considerations of opioid-using-women of all ages. The results of this study could improve the care of women using opioids by informing the strategies of state agencies and impacting legislative efforts for prevention initiatives, substance use disorder treatment, and law enforcement programs.

Emergency physicians play a critical role in mitigating the opioid epidemic in public health. ⋯ The decline in traditional opioid agents such as hydrocodone-acetaminophen was partly offset by an increase in opioids like tramadol, which carry additional potential adverse events. Opioid prescribing rate, average days' supply, and cost of opioid drugs significantly decreased from 2015 to 2019, after a spike in 2015. All regions observed a decrease in emergency physicians, but opioid prescribing rates varied across regions. These trends highlight successful opioid stewardship practices in some areas and the need for further development in others. This information can aid in designing tailored guidelines and policies for emergency physicians to promote effective opioid stewardship practices.
