BACKGROUND
Number of opiate users worldwide has doubled over the past decade, but not all of them are diagnosed with opioid use disorder. We aimed to identify the prevalence and risk factors for OUD after ten years of follow-up.
METHODS
Among 8,500 chronic opiate users at Golestan Cohort Study baseline (2004-2008), we recalled a random sample of 451 subjects in 2017. We used three questionnaires: a questionnaire about current opiate use including type and route of use, the drug use disorder section of the Composite International Diagnostic Interview lifetime version, and the validated Kessler10 questionnaire. We defined opioid use disorder and its severity based on the DSM-5 criteria and used a cutoff of 12 on Kessler10 questionnaire to define psychological distress.
RESULTS
Mean age was 61.2 ± 6.6 years (84.7% males) and 58% were diagnosed with opioid use disorder. Starting opiate use at an early age and living in underprivileged conditions were risk factors of opioid use disorder. Individuals with opioid use disorder were twice likely to have psychological distress (OR = 2.25; 95%CI: 1.44-3.52) than the users without it. In multivariate regression, former and current opiate dose and oral use of opiates were independently associated with opioid use disorder. Each ten gram per week increase in opiate dose during the study period almost tripled the odds of opioid use disorder (OR = 3.18; 95%CI: 1.79-5.63).
CONCLUSIONS
Chronic opiate use led to clinical opioid use disorder in more than half of the users, and this disorder was associated with psychological distress, increasing its physical and mental burden in high-risk groups.

Review
As the United States continues to grapple with the opioid crisis, emergency clinicians are on the front lines of managing patients with opioid use disorder. This issue reviews tools and best practices in emergency department management of patients with opioid overdose and opioid withdrawal, and how substance use history will inform treatment planning and disposition. As growing evidence shows that medications for opioid use disorder (MOUD)- buprenorphine, methadone, and naltrexone-can have lasting impacts on patients' addiction recovery, strategies for assessing patient readiness for MOUD and overcoming barriers to emergency department initiation of these medications are reviewed. Newer approaches to buprenorphine dosing (high-dose, low-dose, home induction, and long-acting injectable dosing) are also reviewed.

Morphine-induced antinociception is partially reduced in interleukin-31 (IL-31) receptor A (IL-31RA)-deficient mice, indicating that IL-31RA is crucial for morphine-induced peripheral antinociception. Herein, we examined the combined effects of IL-31 and morphine on the antinociceptive activity and itch-associated scratching behavior (LLS) in mice and elucidated the regulatory mechanisms. A hot-plate test was used to assess antinociception. LLS was automatically detected and recorded via a computer. IL-31RA mRNA expression was assessed using real-time polymerase chain reaction. Repeated pre-treatment with IL-31 resulted in significant antinociceptive activity. Repeated administration of morphine decreased the morphine-induced antinociceptive activity, LLS counts, and regular dose and inhibited IL-31-induced LLS. These results suggested that the repeated administration of morphine depleted inter-neuronal IL-31RA levels, preventing morphine-induced antinociception. Therefore, IL-31 may be helpful as an adjunct analgesic to morphine. To explore the benefits of IL-31, its influence on morphine-induced antinociceptive tolerance in mice was examined. An IL-31 and morphine combination increased the analgesic action, which increased the expression of DRG neuronal IL-31RA, elucidating the site of peripheral antinociception of morphine. This site may induce exocytosis of IL-31RA in the sensory nervous system. Collectively, the suppressive effect of IL-31 on morphine-induced antinociceptive tolerance may result from IL-31RA supplementation in sensory nerves.

ABSTRAC
BACKGROUND: Treatment of acute pain is an essential element of pre-hospital care for injured and critically ill patients. Clinical studies indicate the need for improvement in the prehospital analgesia.
OBJECTIVE
The aim of this study is to assess the current situation in out of hospital pain management in Germany regarding the substances, indications, dosage and the delegation of the use of analgesics to emergency medical service (EMS) staff.
MATERIAL AND METHODS
A standardized survey of the medical directors of the emergency services (MDES) in Germany was carried out using an online questionnaire. The anonymous results were evaluated using the statistical software SPSS (Chi-squared test, Mann-Whitney-U test).
RESULTS
Seventy-seven MDES responsible for 989 rescue stations and 397 EMS- physician bases in 15 federal states took part in this survey. Morphine (98.7%), Fentanyl (85.7%), Piritramide (61%), Sufentanil (18.2%) and Nalbuphine (14,3%) are provided as opioid analgesics. The non-opioid analgesics (NOA) including Ketamine/Esketamine (98,7%), Metamizole (88.3%), Paracetamol (66,2%), Ibuprofen (24,7%) and COX-2-inhibitors (7,8%) are most commonly available. The antispasmodic Butylscopolamine is available (81,8%) to most rescue stations. Fentanyl is the most commonly provided opioid analgesic for treatment of a traumatic pain (70.1%) and back pain (46.8%), Morphine for visceral colic-like (33.8%) and non-colic pain (53.2%). In cases of acute coronary syndrome is Morphine (85.7%) the leading analgesic substance. Among the non-opioid analgesics is Ketamine/Esketamine (90.9%) most frequently provided to treat traumatic pain, Metamizole for visceral colic-like (70.1%) and non-colic (68.6%) as well as back pain (41.6%). Butylscopolamine is the second most frequently provided medication after Metamizole for "visceral colic-like pain" (55.8%). EMS staff (with or without a request for presence of the EMS physician on site) are permitted to use the following: Morphine (16.9%), Piritramide (13.0%) and Nalbuphine (10.4%), and of NOAs for (Es)Ketamine (74.1%), Paracetamol (53.3%) and Metamizole (35.1%). The dosages of the most important and commonly provided analgesic substances permitted to independent treatment by the paramedics are often below the recommended range for adults (RDE). The majority of medical directors (78.4%) of the emergency services consider the independent application of analgesics by paramedics sensible. The reason for the relatively rare authorization of opioids for use by paramedics is mainly due to legal (in)certainty (53.2%).
CONCLUSION
Effective analgesics are available for EMS staff in Germany, the approach to improvement lies in the area of application. For this purpose, the adaptations of the legal framework as well as the creation of a guideline for prehospital analgesia are useful.

Meta-Analysis Review
BACKGROUND
Cancer-related pain often requires opioid treatment with opioid-induced constipation (OIC) as its most frequent gastrointestinal side-effect. Both for prevention and treatment of OIC osmotic (e.g. polyethylene glycol) and stimulant (e.g. bisacodyl) laxatives are widely used. Newer drugs such as the peripherally acting µ-opioid receptor antagonists (PAMORAs) and naloxone in a fixed combination with oxycodone have become available for the management of OIC. This systematic review and meta-analysis aims to give an overview of the scientific evidence on pharmacological strategies for the prevention and treatment of OIC in cancer patients.
METHODS
A systematic search in PubMed, Embase, Web of Science and the Cochrane Library was completed from inception up to 22 October 2022. Randomized and non-randomized studies were systematically selected. Bowel function and adverse drug events were assessed.
RESULTS
Twenty trials (prevention: five RCTs and three cohort studies; treatment: ten RCTs and two comparative cohort studies) were included in the review. Regarding the prevention of OIC, three RCTs compared laxatives with other laxatives, finding no clear differences in effectivity of the laxatives used. One cohort study showed a significant benefit of magnesium oxide compared with no laxative. One RCT found a significant benefit for the PAMORA naldemedine compared with magnesium oxide. Preventive use of oxycodone/naloxone did not show a significant difference in two out of three other studies compared to oxycodone or fentanyl. A meta-analysis was not possible. Regarding the treatment of OIC, two RCTs compared laxatives, of which one RCT found that polyethylene glycol was significantly more effective than sennosides. Seven studies compared an opioid antagonist (naloxone, methylnaltrexone or naldemedine) with placebo and three studies compared different dosages of opioid antagonists. These studies with opioid antagonists were used for the meta-analysis. Oxycodone/naloxone showed a significant improvement in Bowel Function Index compared to oxycodone with laxatives (MD -13.68; 95 % CI -18.38 to -8.98; I = 58 %). Adverse drug event rates were similar amongst both groups, except for nausea in favour of oxycodone/naloxone (RR 0.51; 95 % CI 0.31-0.83; I = 0 %). Naldemedine (NAL) and methylnaltrexone (MNTX) demonstrated significantly higher response rates compared to placebo (NAL: RR 2.07, 95 % CI 1.64-2.61, I = 0 %; MNTX: RR 3.83, 95 % CI 2.81-5.22, I = 0 %). With regard to adverse events, abdominal pain was more present in treatment with methylnaltrexone and diarrhea was significantly more present in treatment with naldemedine. Different dosages of methylnaltrexone were not significantly different with regard to both efficacy and adverse drug event rates.
CONCLUSIONS
Magnesium oxide and naldemedine are most likely effective for prevention of OIC in cancer patients. Naloxone in a fixed combination with oxycodone, naldemedine and methylnaltrexone effectively treat OIC in cancer patients with acceptable adverse events. However, their effect has not been compared to standard (osmotic and stimulant) laxatives. More studies comparing standard laxatives with each other and with opioid antagonists are necessary before recommendations for clinical practice can be made.

Pain Physician Sep 2023Optimal intrathecal dosing regimens for hydromorphone are not well established for analgesia after abdominal surgery. (Review)
Review
BACKGROUND
Optimal intrathecal dosing regimens for hydromorphone are not well established for analgesia after abdominal surgery.
OBJECTIVES
We reviewed intrathecal hydromorphone doses and complications because dosing variability has been observed among anesthesiologists. We hypothesized that increasing doses of intrathecal hydromorphone would be associated with improved postoperative analgesia, but with increased rates of opioid-related adverse events.
STUDY DESIGN
Retrospective analysis.
SETTING
A high-volume academic referral center in the United States.
METHODS
A retrospective study was conducted of adults undergoing abdominal surgery under general anesthesia supplemented preoperatively with intrathecal hydromorphone for postoperative analgesia from May 5, 2018, through May 31, 2021. Patients were categorized into 3 hydromorphone dosing groups: low-dose (50-100 µg), middle-dose (101-199 µg), and high-dose (200-300 µg). Multivariable logistic regression models were used to assess rates of severe postoperative pain, severe opioid-related adverse events, oversedation, and pruritus in the postanesthesia care unit (PACU) and within 24 hours after PACU discharge.
RESULTS
Of 1,846 patients identified, 1,235 (66.9%) were in the low-dose group; 321 (17.3%), middle-dose group; and 290 (15.7%), high-dose group. Patients receiving the 2 higher doses had more extensive procedures. An unadjusted analysis showed differing rates of severe pain in the PACU by group: 306 (24.8%) in the low-dose, 73 (22.7%) middle-dose, and 45 (15.5%) in the high-dose group (P = 0.003); these differences, however, were no longer significant after an adjusted analysis (P = 0.34). Ten severe opioid-related events occurred; all were recognized in the PACU. Five events each occurred in the low-dose and high-dose groups versus none in the middle-dose group (P = 0.02). No other differences were identified with adjusted analyses.
LIMITATIONS
Limitations of our study include its retrospective design and its conduct at a single center, along with the apparent, but difficult to characterize, treatment biases in hydromorphone dosing.
CONCLUSIONS
No dose response was observed between intrathecal hydromorphone dose and postoperative analgesia, a finding that may reflect treatment bias. Higher rates of severe opioid-related events were detected for patients receiving high-dose hydromorphone in the PACU, but all other safety outcomes were similar between dosing regimens.

CONTEXT
Dyspnea is among the most distressing symptoms in the last weeks to days of life (terminal dyspnea). While physicians frequently use parenteral opioids other than morphine for terminal dyspnea, little is known about their effects in cancer patients.
OBJECTIVES
To explore the effectiveness and safety of parenteral morphine, oxycodone, and hydromorphone for cancer patients with terminal dyspnea.
METHODS
This was a secondary analysis of a multicenter cohort study that consecutively enrolled advanced cancer patients with moderate/severe terminal dyspnea. Participating palliative care physicians initiated parenteral opioids (morphine/oxycodone/hydromorphone), utilizing a standardized treatment algorithm. We examined the dyspnea intensity (Integrated Palliative care Outcome Scale [IPOS]) at 24 and 48 hours.
RESULTS
Of 108 patients (mean age = 72), 66 (61%), 34 (32%), and 8 (7.4%) received morphine, oxycodone, and hydromorphone, respectively. At 24 hours, mean dyspnea IPOS scores significantly decreased from 3.0 (standard error (SE) = 0.1) at the baseline to 1.6 (0.1), 2.9 (0.1) to 2.0 (0.2), and 3.5 (0.2) to 1.2 (0.4) in the morphine (P < 0.001), oxycodone (P < 0.001), and hydromorphone (P = 0.011) groups, respectively. At 48 hours, the IPOS scores significantly reduced from 2.9 (0.1) at the baseline to 1.4 (0.1), 2.9 (0.1) to 1.6 (0.2), and 3.5 (0.2) to 1.2 (0.2) in the morphine (P < 0.001), oxycodone (P < 0.001), and hydromorphone (P = 0.004) groups, respectively. No significant differences in mean scores were found among the three groups at 24 (P = 0.080) and 48 hours (P = 0.322). Adverse events were rare.
CONCLUSION
Parenteral morphine, oxycodone, and hydromorphone may be similarly effective and safe for cancer patients with terminal dyspnea.

AIMS
Excessive opiate analgesia in relation to orthopaedic surgery is associated with morbidity and mortality. Pre-operative use of opiates is associated with higher post-operative use. There is little information about opiate prescribing practices in relation to elective total joint arthroplasty (TJA) in New Zealand rural centres. The aims of this study were to describe opiate use before, immediately after and 1 year after TJA, and to compare prescribing practices with local guidelines.
METHODS
A retrospective cohort study of elective primary hip and knee arthroplasties was conducted between January 2018 and April 2019. Opiate use was evaluated from clinical records and from electronic prescribing records and described in morphine milligram equivalents (MME) with a particular focus on pre-operative and post-operative periods, and use after 1 year.
RESULTS
In the study period, 199 patients underwent 203 joint arthroplasties. Of these, data from 157 patients were analysed. Patient data were not analysed because of unavailable files (N=20), non-elective procedures (N=11), bilateral arthroplasties (N=4), deaths (N=4) and incomplete information (N=3). Pre-operative opiates were used by 92 (59%) patients, of whom 70 (76%) were not using opiates after 1 year. There were 126 (80%) patients who were discharged with opiate prescriptions and the vast majority, 121 (96%), did not receive discharge prescriptions that conformed to local guidelines.
CONCLUSION
Despite undergoing joint arthroplasty, about one quarter of patients who had been prescribed opiates before the operation were still receiving opiates after 1 year. There was poor compliance with local guidelines.
