Journal: Analysis of 29 fentanyl analogs and their fragmentation mechanism by liquid chromatography-quadrupole time-of-flight mass spectrometry (Pubmed Central) - Jan 12, 2022 This method is rapid, simple, time-saving, highly sensitivity and stable, and it is applicable to a wide variety of samples. Hence, it is suitable for the identification, confirmation, and quantitative detection of the 29 fentanyl analogs in drugs, solids or powders containing sugar, beverages, drinking water, wine samples, etc.

Preclinical, Journal: Human histamine H receptors can initiate cardiac arrhythmias in a transgenic mouse. (Pubmed Central) - Jan 11, 2022 However, compounds reported to release histamine from cells and thereby leading to arrhythmias in humans, namely morphine, ketamine, and fentanyl, failed to induce a more pronounced positive inotropic effect in atrial preparations from H-TG compared to WT, arguing against an involvement of histamine release in their proarrhythmic side effects in patients...In summary, we noted that overexpression of human H-histamine receptors in a novel transgenic animal model can lead to arrhythmias. We suggest that this model might be useful to understand the mechanism(s) of histamine-induced cardiac arrhythmias in humans better in a molecular way and may be of value to screen novel antiarrhythmic drugs.

Clinical, Journal: Polysubstance Use Among Patients Treated With Buprenorphine From a National Urine Drug Test Database. (Pubmed Central) - Jan 11, 2022 While buprenorphine can curtail harmful opioid use, co-occurring use of nonprescribed substances, such as cocaine, methamphetamine, and other opioids, may negatively affect treatment outcomes...From 2013 to 2019, positivity rates increased for most substances (eg, fentanyl: from 131 of 21 412 [0.61%] to 1464 of 13 597 [10.77%])...In this cross-sectional study, patterns of nonprescribed substance positivity among patients prescribed buprenorphine varied widely. This study highlights the utility of UDT in public health surveillance efforts related to patients treated with buprenorphine for OUD.

Journal: Catheter-mounted smart hydrogel ultrasound resonators for intravenous analyte monitoring. (Pubmed Central) - Jan 11, 2022 Selectivity to different drugs, e.g., fentanyl, can be accomplished by developing a corresponding smart hydrogel composition.Clinical Relevance- Many intravenous medications, especially anesthetics, show considerable pharmacokinetic inter-subject variability. Continuous monitoring of intravenous analyte concentrations would enable individualizing the administration of these drugs to the specific patient.

Preclinical, Journal: Effects of opioids and benzodiazepines on bladder function of awake restrained mice. (Pubmed Central) - Jan 8, 2022 The presence of electrodes next to the EUS does not obstruct the bladder outlet. Opioids and benzodiazepines severely interfere with physiological bladder function: fentanyl and hydromorphine disrupted the voiding phase evidenced by the reduced coordination of EUS activity with detrusor contraction, while bladder emptying under midazolam was achieved by EUS relaxation only.

Clinical, Journal: Impact of changes in opioid funding and clinical policies on rapid tapering of opioids in Ontario, Canada. (Pubmed Central) - Jan 7, 2022 The monthly prevalence of rapid tapering events was stable from January 2014 to September 2016 (average monthly prevalence: 1.4%) but increased from 1.4% in October 2016 to 1.8% in April 2017 (P = 0.001), coincident with Ontario's Fentanyl Patch-for-Patch Return Program implementation...Our sensitivity analysis examining longer-lasting rapid tapering found similar trends but lower prevalence, with no changes in complete discontinuation. These temporary increases in rapid tapering events highlight the need for improved communication and evidence-based resources for prescribers to minimize negative consequences of evolving policies and guidelines.

Review, Journal: Intraoperative Methadone Use in Cardiac Surgery: A Systematic Review. (Pubmed Central) - Jan 7, 2022 Intraoperative methadone use reduces acute postoperative pain and lowers opioid consumption in comparison with morphine and fentanyl. Initial results suggest that methadone may be an equivalent opioid to be administered during cardiothoracic procedures to reduce acute postsurgical pain, though further research is warranted.

Retrospective data, Review, Journal: Intravenous Dexmedetomidine as an Adjunct to Neuraxial Anesthesia in Cesarean Delivery: A Retrospective Chart Review. (Pubmed Central) - Jan 7, 2022 While the use of inotropic/vasopressor medications was common and similar in both groups, there was an increase in the incidence of bradycardia (Dexmed 15% vs. Standard 2%; p=0.042) but not hypotension (Dexmed 24% vs. Standard 24%; p=1.00) in the Dexmed group. In patients who required supplemental analgesia for cesarean delivery, those who received dexmedetomidine versus other medications had a similar rate of conversion to general anesthesia, a statistically significant increase in bradycardia, but no difference in the incidence of hypotension.

Journal: Cannabinoid CB Receptor Activation Attenuates Fentanyl-Induced Respiratory Depression. (Pubmed Central) - Jan 4, 2022 Moreover, the CB agonist, administered alone, did not alter respiration. Our findings suggest that the CB cannabinoid agonist LY2828360 may provide CB-mediated protection against fentanyl-induced respiratory depression, a detrimental and unwanted side effect of opioid use and abuse.
