Preclinical, Journal: Effects of anesthesia on renal function and metabolism in rats assessed by hyperpolarized MRI. (Pubmed Central) - Sep 20, 2019 Inactin and sevoflurane were found to affect the renal hemodynamic and metabolic status to a lesser degree than FFM. Sevoflurane anesthesia is particularly easy to induce and maintain during the whole anesthesia procedure, and as such, represents a good alternative to inaction, although it alters the blood glucose level.

Journal: Utilizing resources of neuropsychopharmacology to address the opioid overdose crisis. (Pubmed Central) - Sep 20, 2019 Although more research on the genetic factors that influence opioid sensitivity is needed, analgesic requirements may be predicted by analyzing ATF2SNPs, together with other polymorphisms of genes that are reportedly associated with opioid sensitivity, such as CREB1, OPRM1, and GIRK2. Hopefully, this crisis will reinvigorate both basic and clinical neuropsychopharmacological research leading to the develop new and more effective options for dealing with the many and varied elements of the current opioid crisis as described in the present commentary.

Clinical, Journal: Comparison of Fentanyl and Dexmedetomidine as Intrathecal Adjuvants to Spinal Anaesthesia for Abdominal Hysterectomy. (Pubmed Central) - Sep 20, 2019 Hopefully, this crisis will reinvigorate both basic and clinical neuropsychopharmacological research leading to the develop new and more effective options for dealing with the many and varied elements of the current opioid crisis as described in the present commentary. Dexmedetomidine is better than Fentanyl as an intrathecal adjuvant to spinal anaesthesia in minimizing visceral pain during abdominal hysterectomy and in prolonging post-operative analgesia.

Journal: It is time for an ethical, evidence-based approach to youth presenting to the ED with an opioid overdose. (Pubmed Central) - Sep 19, 2019 Currently, there is a dangerous inconsistency between our current understanding of adolescent development and the effects of drugs on cognition when compared to our collective approach to youth who present in the emergency department with an opioid overdose. We call upon practitioners to embrace a new paradigm and we ask the Canadian Pediatric Society (CPS) to spearhead the development of guidelines to advise on best practices to manage youth who present to the emergency department with an illicit drug overdose.

We synthesized and tested analogs of fentanyl possessing one or two fluorine atoms at the beta position of the phenethylamine side chain, with additional fluorines optionally added to the benzene ring of the side chain...The novel bis-fluorinated analog RR-49 showed superior pH sensitivity, with full efficacy relative to DAMGO, but with 19-fold higher potency (IC) in a MOR cAMP assay at pH 6.5 versus 7.4. Such compounds hold significant promise as analgesics for inflammatory pain with reduced abuse potential.

Review, Journal: Opioids and the immune system - friend or foe. (Pubmed Central) - Sep 14, 2019 However, the results are inconsistent: Exogenous opioids such as morphine and fentanyl have been found to impair the function of macrophages, natural killer cells and T-cells and to weaken the gut barrier in vitro and in animal studies...In summary, there is a reciprocal interaction between the immune system and endogenous as well as exogenous opioids. In addition to the existing epidemiological studies, controlled clinical studies are necessary in the future to delineate the role of the opioid-immune system interaction in patients and estimate the clinical relevance of it.

Clinical, Review, Journal: Influence of opioids on immune function in patients with cancer pain: from bench to bedside. (Pubmed Central) - Sep 14, 2019 Animal models have shown that this is not a class effect, in that morphine and fentanyl suppress NK cell cytotoxicity; buprenorphine does not affect NK cell cytotoxicity, whereas tramadol increases NK cell cytotoxicity, reducing metastasis...Pain is immunosuppressive, so analgesia is important. Opioids for cancer-related pain will continue to be recommended until definitive data on the effects of opioids on clinical outcomes in specific patient groups becomes available.

Journal: Physico-chemical stability of Plasma-Lyte 148 and Plasma-Lyte 148 + 5% Glucose with eight common intravenous medications. (Pubmed Central) - Sep 14, 2019 Morphine, fentanyl, ketamine, salbutamol, aminophylline, and clonidine are stable for 24 hours when mixed with Plasma-Lyte 148® and Plasma-Lyte 148®+5% Glucose for administration at concentrations equivalent to those found at a typical Y-site with maintenance fluid. Furosemide is stable at lower concentrations than those seen at a Y-site, but midazolam displayed instability.

Clinical, Journal: Incidence of Long-term Opioid Use Among Opioid-Naive Patients With Hidradenitis Suppurativa in the United States. (Pubmed Central) - Sep 13, 2019 The most frequent schedule II opioid prescriptions included oxycodone hydrochloride (55 of 74 patients [74.3%]), hydrocodone bitartrate (44 [59.5%]), hydromorphone hydrochloride (16 [21.6%]), morphine sulfate (13 [17.6%]), and fentanyl citrate (6 [8.1%])...In this study, patients with HS were at higher risk for long-term opioid use. These results suggest that periodic assessment of pain and screening for long-term opioid use may be warranted, particularly among patients who are older, who smoke tobacco, or who have depression and other medical comorbidities.

Journal: Editorial: Advances in Analytical Methods for Drugs of Abuse Testing.

Journal: Covalent Poly(lactic acid) Nanoparticles for the Sustained Delivery of Naloxone. (Pubmed Central) - Sep 10, 2019 This protocol afforded well-defined nanoparticles possessing a drug loading of approximately 7% w/w. The resulting Nal-cNPs demonstrated excellent biocompatibility, while exhibiting sustained linear release kinetics in vitro and blocking the effects of high dose (10 mg/kg) acute morphine for up to 98 h in an in vivo rodent model of neuropathic pain.
