Clinical, Journal: Detecting risk level in individuals misusing fentanyl utilizing posts from an online community on Reddit. (Pubmed Central) - Nov 24, 2021 Moreover, our vocabulary of online terms for fentanyl and its analogues expands our understanding of online "street" nomenclature for opiates. Through an improved understanding of substance misuse risk factors, these findings allow for identification of risk concepts among those misusing fentanyl to inform outreach and intervention strategies tailored to this at-risk group.

Preclinical, Journal: Respiratory effects of low and high doses of fentanyl in control and β-arrestin 2 deficient mice. (Pubmed Central) - Nov 24, 2021 The ventilatory effects of fentanyl in b-arr2 deficient mice reported in the literature are primarily mediated by the "indirect" effects of sedation/hypometabolism on breathing control. There was an excess mortality at very high doses of fentanyl in the b-arr2 deficient mice, which mechanisms are still open to question, since the capacity of maintaining a rhythmic, although profoundly depressed, breathing activity remains similar in all of the surviving control and b-arr2 deficient mice.

Journal: Design, synthesis, and preliminary evaluation of a potential synthetic opioid rescue agent. (Pubmed Central) - Nov 24, 2021 Methods have been developed that have utility to identify enhanced rescue agents for the treatment of OIRD. Analogue 29, possessing potent MOR antagonist activity in vitro and in vivo, provides a promising lead in our search for an enhanced synthetic opioid rescue agent.

Journal: Is Opioid-free Anesthesia Possible by Using Erector Spinae Plane Block in Spinal Surgery? (Pubmed Central) - Nov 22, 2021 Analogue 29, possessing potent MOR antagonist activity in vitro and in vivo, provides a promising lead in our search for an enhanced synthetic opioid rescue agent. ESP block decreases opioid consumption and VAS score at postoperative one hour in patients, and also patients who receive ESP block do not require intraoperative opioid administration.

Clinical, Journal: Thirteen Cases of Valeryl Fentanyl in Michigan: A Call for Expanding Opioid Testing. (Pubmed Central) - Nov 21, 2021 Given the paucity of pharmacodynamic information, the prohibition of its use, the potential to buttress law enforcement efforts in monitoring drug trafficking trends, and to determine the efficacy of current regulations, laboratories should test for valeryl fentanyl. When testing for valeryl fentanyl, and likely other fentanyl analogs, the site of sample collection is important: central sources of blood are preferred to peripheral sources.

Review, Journal: The opioid crisis and HIV in the USA: deadly synergies. (Pubmed Central) - Nov 21, 2021 Opioid overdose death rates have increased steadily for more than a decade and doubled in 2013-17, as the highly potent synthetic opioid fentanyl entered the drug supply...If the USA is serious about HIV prevention among this group, stigma must be eliminated, discriminatory policies must change, and comprehensive health care must be accessible to all. Finally, root causes of the opioid epidemic such as hopelessness need to be identified and addressed.

Review, Journal: Recent Advances in Peripheral Opioid Receptor Therapeutics. (Pubmed Central) - Nov 21, 2021 Recent innovations in peripheral opioid receptor therapeutics of pH-sensitive opioid ligands and limiting opioid permeability across the blood-brain barrier have had promising results in animal models. While this is grounds for optimism that some of these therapeutics will be efficacious in human subjects at a future date, each drug must undergo individualized testing for specific chronic pain syndromes to establish not only the nuances of each drug's therapeutic effect but also a comprehensive safety profile.

Retrospective data, Journal: Opioid-related deaths before and after COVID-19 stay-at-home orders in Los Angeles County. (Pubmed Central) - Nov 21, 2021 The increase in opioid-related overdose deaths following the onset of COVID-19 and related policies occurred most often among Non-Hispanic Caucasian individuals. Further research on this trend's underlying cause is needed to inform policy recommendations during these simultaneous public health crises.

Journal: Growing racial/ethnic disparities in overdose mortality before and during the COVID-19 pandemic in California. (Pubmed Central) - Nov 21, 2021 Growing racial disparities in overdose must be understood in the context of the unequal social and economic fallout from the COVID-19 pandemic, during which time Black communities have been subjected to the dual burden of disproportionate COVID-19 deaths and rising overdose mortality. Increased investments are required to ameliorate racial/ethnic disparities in substance use treatment, harm reduction, and the structural drivers of overdose, as part of the COVID-19 response and post-pandemic recovery efforts.

Journal: Is Europe Facing an Emerging Opioid Crisis Comparable to the U.S.? (Pubmed Central) - Nov 17, 2021 In the U.S., an opioid overdose crisis has emerged, attributable to over-prescription of opioid analgesics, driven by aggressive marketing by pharmaceutical companies, followed by surging heroin overdose deaths, and more recently, by the high mortality rates predominately because of illicitly manufactured fentanyl and analogs of fentanyl...Considering that the use of prescription opioids has been declining rather than increasing in Europe, an opioid crisis is not anticipated there yet. Authorities should, however, remain vigilant.

A single-center experience () - Nov 16, 2021 - Abstract #SNO2021SNO_1242; Conscious sedation was the anesthetic technique (propofol, fentanyl, and NSAIDs)...CONCLUSION Tumor resection in awake patients showed to be a safe procedure, and well tolerated by the patients. Preoperative planning of anatomical and functional aspects and intraoperative neurophysiological assessment are the cornerstones for pursuing maximal safe resection.

Journal: Quantification of Classic, Prescription, and Synthetic Opioids in Hair by LC-MS-MS. (Pubmed Central) - Nov 16, 2021 The linearity range was 1-500 pg/mg for fentanyl and synthetic opioids and 10-500 pg/mg for prescription and classic opioids...This method was applied to 64 authentic cases, identifying 13 compounds from our panel. A sensitive and specific method was developed for the identification and quantification of 27 classic, prescription and synthetic opioids in hair by LC-MS-MS.
