Multicenter StudyBreakthrough cancer pain in patients with abdominal visceral cancer pain.
The objective of this study was to assess the characteristics of breakthrough cancer pain (BTcP) in patients with abdominal cancer pain, and the eventual factors associated with its presentation. ⋯ Patients with abdominal visceral BTcP represent a subgroup with specific features of BTcP, particularly those with predictable BTcP. Ingestion of food was the prominent trigger for BTcP, having a faster onset and a lower intensity. This group of patients more frequently used oxycodone/naloxone or no anti-inflammatory drugs. These findings suggest consequential therapeutic decisions.

Randomized Controlled Trial Multicenter Study
Effect on morphine requirement of early administration of oral acetaminophen versus acetaminophen/tramadol combination in acute pain.
To evaluate the effect on opioid requirement of pain treatment starting at triage, and to evaluate satisfaction in emergency department (ED) patients with acute pain. ⋯ Oral tramadol/acetaminophen combination administered early in triage was associated with a decrease in intravenous morphine requirement and increase in satisfaction among ED patients with acute pain when compared with patients taking acetaminophen. No significant increase in side effects was found. This intervention may be considered in EDs with an aim of similar benefits.

Background Morphine administration is a strong predictor of delayed onset of action of orally administered ticagrelor in patients with ST-segment-elevation myocardial infarction, likely because of impaired gastrointestinal motility. The aim of this study was to evaluate whether the peripheral opioid antagonist methylnaltrexone could improve pharmacodynamics and pharmacokinetics of orally administered ticagrelor in patients with ST-segment-elevation myocardial infarction receiving morphine. Methods and Results The MOVEMENT (Methylnaltrexone to Improve Platelet Inhibition of Ticagrelor in Morphine-Treated Patients With ST-Segment Elevation Myocardial Infarction) trial was a multicenter, prospective, randomized, controlled trial in patients with ST-segment-elevation myocardial infarction treated with morphine and ticagrelor. ⋯ Conclusions Methylnaltrexone did not significantly improve platelet reactivity or plasma concentrations of orally administered ticagrelor in patients with ST-segment-elevation myocardial infarction receiving morphine. Clinical Trial Registration URL : http://www.clinicaltrials.gov. Unique identifier: NCT 02942550.

Studies on the effectiveness of multimodal analgesia, particularly in patients at higher perioperative risk from obstructive sleep apnoea (OSA), are lacking. We aimed to assess the impact of multimodal analgesia on opioid use and complications in this high-risk cohort. ⋯ In a population at high risk for perioperative complications from OSA, multimodal analgesia was associated with a stepwise reduction in opioid use and complications, including critical respiratory failure.

Multicenter Study
Intravenous Misuse of Methadone, Buprenorphine and Buprenorphine-Naloxone in Patients Under Opioid Maintenance Treatment: A Cross-Sectional Multicentre Study.
The act of intravenous misuse is common in patients under opioid maintenance treatment (OMT), but information on associated factors is still limited. ⋯ We offered new information on factors associated with intravenous OMT misuse, repeated misuse and ER admission in Italian patients under OMT. Our data indicate that BUP-NLX misuse is not different from that of BUP or MET. Choosing the more expensive BUP-NLX over MET will likely not lead to the expected reduction of the risk of injection misuse of the OMT. Instead of prescribing new and expensive OMT formulations, addiction unit physicians and medical personnel should better focus on patient's features that are associated with a higher likelihood of misuse. Care should be paid to concurrent benzodiazepine and OMT misuse.
