Continuous quality improvement: reducing informed consent form signing errors.

BACKGROUND: Adherence to ethical guidelines and regulations and protecting and respecting the dignity and autonomy of participants by obtaining a valid informed consent form (ICF) prior to participation in research are crucial; The subjects did not add signatures next to the corrections made to signatures or dates on the ICF, Multiple signatures in other fields, ICF missing/missing signature, Incorrect ICF version Signed after modification, Correction tape used to correct signature, Impersonated signature, Non-research-member signature, however, ICFs are often not properly completed, which must be addressed. This study analyzed ICF signing errors and implemented measures to reduce or prevent these errors. METHODS: We used the plan-do-check-act (PDCA) cycle to help improve the correctness and validity of ICF signing. RESULTS: Interim and final reports from January 2016 to February 2020 including 363 ICFs were studied. The total proportion of correct ICF signatures (200, 83.3%) following the PDCA intervention was significantly higher than that before the intervention (P < 0.05). Analysis of the types of signing error demonstrated that signature errors were significantly reduced after the intervention, particularly for subjects did not add signatures next to the corrections made to signatures or dates on the ICF (16, 6.7%) and impersonated signature (0; P < 0.05). CONCLUSIONS: The proportions of other error types-multiple signatures in other fields, missing or unsigned ICF, incorrect signature order, incorrect ICF version, use of correction tape to correct signature, and non-medical profession members signing the ICF-did not differ significantly.

Teneligliptin Co-Infusion Alleviates Morphine Tolerance by Inhibition of Spinal Microglial Cell Activation in Streptozotocin-Induced Diabetic Rats.

Morphine (MOR) is a commonly prescribed drug for the treatment of moderate to severe diabetic neuropathic pain (DNP). However, long-term MOR treatment is limited by morphine analgesic tolerance (MAT). The activation of microglial cells and the release of glia-derived proinflammatory cytokines are known to play an important role in the development of MAT. In this study, we aimed to investigate the effects of the dipeptidyl peptidase-4 inhibitor (DPP-4i) teneligliptin (TEN) on MOR-induced microglial cell activation and MAT in DNP rats. DNP was induced in four groups of male Wistar rats through a single intraperitoneal injection of streptozotocin (STZ) (50 mg/kg, freshly dissolved in 5 mmol/L citrate buffer, pH 4.5). Sham rats were administered with the vehicle. Seven days after STZ injection, all rats were implanted with an intrathecal (i.t) catheter connected to a mini-osmotic pump, divided into five groups, and infused with the following combinations: sham + saline (1 µL/h, i.t), DNP + saline (1 µL/h, i.t), DNP + MOR (15 µg/h, i.t), DNP + TEN (2 µg/h, i.t), and DNP + MOR (15 µg/h, i.t) + TEN (2 µg/h, i.t) for 7 days at a rate of 1 µL/h. The MAT was confirmed through the measurement of mechanical paw withdrawal threshold and tail-flick tests. The mRNA expression of neuroprotective proteins nuclear factor erythroid 2-related factor (Nrf2) and heme oxygenase-1 (HO-1) in the dorsal horn was evaluated by quantitative PCR (qPCR). Microglial cell activation and mononucleate cell infiltration in the spinal cord dorsal horn were assessed by immunofluorescence assay (IFA) and Western blotting (WB). The results showed that co-infusion of TEN with MOR significantly attenuated MAT in DNP rats through the restoration of neuroprotective proteins Nrf2 and HO-1 and suppression of microglial cell activation in the dorsal horn. Though TEN at a dose of 2 µg has mild antinociceptive effects, it is highly effective in limiting MAT.

Vitamin D reduces pain and cartilage destruction in knee osteoarthritis animals through inhibiting the matrix metalloprotease (MMPs) expression.

Aim of the study: In this study, we investigated the therapeutic potential of vitamin D (VITD) in OA Wistar rats induced by anterior cruciate ligament transection combined with medial meniscectomy (ACLT + MMx). In ACLT + MMx-induced OA rats, pain severity, cartilage destruction, inflammatory cytokines, and MMPs were all measured. Materials and methods: ACLT + MMx methods were used to induce OA, and pain behavioral studies such as the weight bearing test and paw withdrawal test were performed while the knee width and body weights were also measured. Furthermore, Hematoxylin and Eosin (H&E) staining was used to determine knee histopathological studies, as well as OARSI scoring, cartilage thickness, cartilage width, and cartilage degradation scores. The enzyme-linked immunosorbent assay (ELISA) studies were used to check the serum levels of VITD, C-telopeptide of Type II collagen (CTX-II), and pro-inflammatory cytokines tumor necrosis factor-α (TNF-α), interleukin-1ß (IL-1ß), interleukin-6 (IL-6), and anti-inflammatory cytokines interleukin-10 (IL-10), and MMPs (MMP-3, MMP-9, and MMP-13). Finally, the reverse transcription polymerase chain reaction (RT-PCR) test was used to determine the levels of MMPs, nuclear factor-kappa B (NF-κB), TNF-α, IL-6, and IL-10 in IL-1ß stimulated chondrocytes. Results: The oral VITD supplement significantly reduced OA pain, inflammation, cartilage destruction, and MMPs levels. Furthermore, serum VITD levels increased while CTX-II levels decreased, indicating that VITD reduced cartilage degradation effectively. Moreover, VITD supplementation reduced the expression of pro-inflammatory TNF-α, IL-1ß, and IL-6 cytokines while increasing the expression of anti-inflammatory IL-10. The elevation of MMPs after ACLT + MMx surgery contributed to articular cartilage destruction, which was reduced by VITD supplementation. Finally, VITD supplementation significantly reduces serum levels of MMPs, IL-1ß, TNF-α, and IL-6 while increasing IL-10 levels. Then, using the in-vitro cytotoxicity (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) MTT assay, examine the cytotoxicity profile of VITD in rat chondrocytes after stimulated with IL-1ß, which shows no toxicity in the dose range of VITD 0-500 IU. Finally, RT-PCR studies in IL-1ß stimulated rat chondrocytes revealed that VITD (50, 100, and 500 IU) significantly reduced the mRNA levels of MMPs, NF-κB, TNF-α, and IL-6, while increasing IL-10 levels, indicating that VITD reduced chondrocyte destruction and overcame harsh conditions in a dose-dependent manner. Conclusion: Overall, the in vivo and in vitro findings show that VITD effectively reduces OA pain, inflammation, and chondrocyte destruction by lowering MMPs levels specifically.

Injection Site Reactions Before and After Intramuscular Injection Technique Revision: A Postmarketing Analysis of NALDEBAIN® From 2017 to 2022.

BACKGROUND: The NALDEBAIN® has been available since 2017, and high incidence of injection reactions in the phase 3 study has been reported. Since the first year in the market, the injection site reactions were still the majority of adverse drug reactions (ADRs) in pharmacovigilance reports. The new intramuscular (IM) instruction and package was introduced in the middle of 2018. In this retrospective study, we analyzed the pharmacovigilance data and published postmarketing studies to investigate the impact of IM injection-related reactions in Taiwan between the period of 2017-2022. METHODS: Individual case safety reports (ICSRs) and ADRs were classified by system organ class and preferred term. The reporting rate of ICSRs was used to evaluate the impact of the new IM instruction and package. RESULTS: A total of 37 ICSRs were identified from pharmacovigilance reports. Among them, 51% of IM injection-related reactions were reported after one single dose of NALDEBAIN administration. The reporting rate of IM injection-related reactions in pharmacovigilance data dropped from 125.00 to 3.56 per ten thousand exposures after IM instruction and package revision in 2018. In addition, the percentage of IM injection-related reactions also reduced in postmarketing studies from 27.5% to 4.5%. There were no serious IM injection-related reactions found in the pharmacovigilance and postmarketing dataset. CONCLUSION: Injection site reactions were common after intramuscularly administered oil-based agents during the first year which is later markedly reduced by changing the length of the needle and injection education.

Multimodal Analgesia With Extended-Release Dinalbuphine Sebacate for Perioperative Management: Expert Opinion and Consensus.

BACKGROUND: The insufficient treatment of postoperative pain is considered a major barrier to enhanced patient recovery following surgery. Opioids remain the standard therapy for postoperative pain; however, the epidemic crisis of opioid abuse in the US has resulted in opioid-sparing multimodal analgesia (MMA) strategies in anesthesia practice. Complete perioperative pain management, particularly after discharge, may be undermined, resulting in chronic postsurgical pain. Thus, anesthesiologists and pain physicians should provide comprehensive MMA guidance for perioperative pain management. METHODS: The Taiwan Pain Society organized a working group, which included experts in the field of anesthesia, pain, and surgery. This group performed an extensive literature search, quality review, and drafted a consensus, which was discussed by experts and edited for feedback. Recommendations covered consent instruction, treatment interventions, intramuscular injection techniques, and prophylaxis for postoperative adverse events. RESULTS: This consensus included (1) a comparison of the pharmacology and pharmacokinetics between nalbuphine and dinalbuphine sebacate, (2) recommendations to help clinicians establish MMA with extended-release dinalbuphine sebacate injection, and (3) management of common adverse events during the perioperative pain period. CONCLUSION: Extended-release dinalbuphine sebacate combined with the MMA strategy can reduce the medical burden and improve the quality of recovery following surgery.

Case Report: Successful Reversal of Residual Block with Sugammadex in a Patient Not Known to Have Myasthenia Gravis.

BACKGROUND Incomplete recovery from residual neuromuscular block agent (NMBA) after anesthesia is a serious adverse event in the post-anesthesia care unit. Acetylcholinesterase neostigmine is usually used to reverse residual neuromuscular blockade and facilitate spontaneous breathing and endotracheal extubation. CASE REPORT A 40-year-old woman received general anesthesia for strabismus correction surgery. At the end of surgery, repeated doses of neostigmine up to 85 µg/kg failed to reverse the residual neuromuscular blockade (train-of-four [TOF] ratio below 21%). Sugammadex (200 mg) provided immediate reversal, with the TOF ratio up to 100%. The patient regained spontaneous breathing, and the endotracheal tube was removed. After surgery, myasthenia gravis was diagnosed. CONCLUSIONS When unexpected prolonged neuromuscular blockade presents, the TOF ratio should be used to detect its depth and guide a reasonable dose of reversal agents. Anticholinesterase has a ceiling effect; once acetylcholinesterase activity is fully inhibited, administration of additional anticholinesterase can result in no further recovery. Furthermore, excessive acetylcholine can cause muscle weakness. In contrast, sugammadex is a selective reversal agent for steroidal NMBA, which works by encapsulation via tight water-soluble complexes with amino steroids (eg, rocuronium) rather than increasing acetylcholine at the neuromuscular junction. In this case, the recovery from moderate neuromuscular blockade by sugammadex was more effective and rapid than that by neostigmine. When refractory and prolonged residual neuromuscular blockade presents after repeated doses of anticholinesterase, sugammadex should be considered as an effective reversal agent. Particularly in cases of myasthenia gravis, sugammadex is superior to neostigmine for reversing rocuronium-induced NMBA in patients undergoing surgery.

Carnosine Alleviates Knee Osteoarthritis and Promotes Synoviocyte Protection via Activating the Nrf2/HO-1 Signaling Pathway: An In-Vivo and In-Vitro Study.

The most common joint disease in the elderly is knee osteoarthritis (OA). It is distinguished by cartilage degradation, subchondral bone loss, and a decrease in joint space. We studied the effects of carnosine (CA) on knee OA in male Wistar rats. OA is induced by anterior cruciate ligament transection combined with medial meniscectomy (ACLT+MMx) method and in vitro studies are conducted in fibroblast-like synoviocyte cells (FLS). The pain was assessed using weight-bearing and paw-withdrawal tests. CA supplementation significantly reduced pain. The enzyme-linked immunosorbent assay (ELISA) method was used to detect inflammatory proteins in the blood and intra-articular synovial fluid (IASF), and CA reduced the levels of inflammatory proteins. Histopathological studies were performed on knee-tissue samples using toluidine blue and hematoxylin and eosin (H and E) assays. CA treatment improved synovial protection and decreased cartilage degradation while decreasing zonal depth lesions. Furthermore, Western blotting studies revealed that the CA-treated group activated nuclear factor erythroid 2-related factor (Nrf2) and heme oxygenase (HO-1) and reduced the expression of cyclooxygenase-2 (COX-2). FLS cells were isolated from the knee joints and treated with IL-1ß to stimulate the inflammatory response and increase reactive oxygen species (ROS). The matrix metalloproteinase protein (MMP's) levels (MMP-3, and MMP-13) were determined using the reverse transcription-polymerase chain reaction (RT-PCR), and CA treatment reduced the MMP's expression levels. When tested using the 2',7'-dicholorodihydrofluroscene diacetate (DCFDA) assay and the 5,5',6,6'-tetracholoro-1,1',3,3'-tertraethylbenzimidazolcarboc janine iodide (JC-1) assay in augmented ROS FLS cells, CA reduced the ROS levels and improved the mitochondrial membrane permeability. This study's investigation suggests that CA significantly alleviates knee OA both in vitro and in vivo.

Sugammadex reversal of muscle relaxant blockade provided less Post-Anesthesia Care Unit adverse effects than neostigmine/glycopyrrolate.

Sugammadex is a direct reversal agent of aminosteroid muscle relaxants, particularly rocuronium, with promptly and completely reverse of deep neuromuscular block (NMB), which allows better surgical conditions. Sugammadex exhibits advantages over indirect reversal agent acetylcholinesterase inhibitor neostigmine with less adverse effects. In this retrospective review, we compared the incidence of postoperative vomiting (POV), postoperative urinary retention (POUR), and hemodynamic changes between sugammadex and neostigmine/glycopyrrolate in reversal of muscular blockade. Sugammadex showed superior in all three aspects. The heart rate was 7.253 lower (P < 0.0001) and mean arterial pressure was 5.213 lower (P < 0.0001) in sugammadex group. The POV of neostigmine/glycopyrrolate group was 3.16 times more than sugammadex group (OR = 3.16, p < 0.0001), and POUR of neostigmine/glycopyrrolate group was 4.291 times more than sugammadex group (OR = 4.291, p < 0.0001). Sugammadex showed better hemodynamic stability, and lower incidence of POV and POUR than neostigmine/glycopyrrolate.

New Advances on Pathophysiology of Diabetes Neuropathy and Pain Management: Potential Role of Melatonin and DPP-4 Inhibitors.

Pre-diabetes and diabetes are growing threats to the modern world. Diabetes mellitus (DM) is associated with comorbidities such as hypertension (83.40%), obesity (90.49%), and dyslipidemia (93.43%), creating a substantial burden on patients and society. Reductive and oxidative (Redox) stress level imbalance and inflammation play an important role in DM progression. Various therapeutics have been investigated to treat these neuronal complications. Melatonin and dipeptidyl peptidase IV inhibitors (DPP-4i) are known to possess powerful antioxidant and anti-inflammatory properties and have garnered significant attention in the recent years. In this present review article, we have reviewed the recently published reports on the therapeutic efficiency of melatonin and DPP-4i in the treatment of DM. We summarized the efficacy of melatonin and DPP-4i in DM and associated complications of diabetic neuropathy (DNP) and neuropathic pain. Furthermore, we discussed the mechanisms of action and their efficacy in the alleviation of oxidative stress in DM.

Multimodal Analgesia with Extended-Release Dinalbuphine Sebacate for Perioperative Pain Management in Upper Extremity Trauma Surgery: A Retrospective Comparative Study.

INTRODUCTION: Patients undergoing upper extremity fracture surgery (UEFS) commonly suffer from unbearable acute pain. Opioids remain the mainstay of moderate to severe pain alleviation, although there is a growing concern regarding the increasing trend in misuse and abuse. This study aimed to observe the safety and efficacy of dinalbuphine sebacate (DS), a novel extended-release analgesic, along with multimodal analgesia (MMA) for post-UEFS pain control. METHODS: We retrospectively reviewed the records of patients undergoing UEFS between August 2020 and January 2021. Eligible patients were included and divided into two groups, depending on the analgesic regimen. In the DS group, 150 mg DS was administered intramuscularly at least 12 h pre-operatively, while in the conventional analgesia (CA) group, 40 mg parecoxib was given within 3 h before surgery. Intraoperative fentanyl administration was guided by the Analgesia Nociception Index System in both groups. For breakthrough pain, fentanyl was used as rescue medicine in the postanaesthesia care unit while tramadol and parecoxib were administered in the ward. RESULTS: Forty-nine patients were allocated to the DS group and 60 patients were allocated to the CA group. In comparison with the CA group, the proportion of patients requiring opioids for breakthrough pain post-operatively was significantly lower in the DS group (fentanyl: 31% vs. 68%, p < 0.001; tramadol: 27% vs. 70%, p < 0.001). The DS group also consumed lower amounts of post-operative rescue opioids. Furthermore, both mean worst and least pain scores were significantly lower in the DS group from post-operative day (POD) 1 to POD 5. There was no significant difference in intraoperative consumption of fentanyl or incidence of adverse events. CONCLUSION: This result suggests that extended-release DS is a suitable analgesic incorporated in MMA and a promising solution to the misuse and abuse of opioids.

Implications of Cardiovascular Disease for Assessment and Treatment of Nocturia in Primary Care: Systematic Review and Nominal Group Technique Consensus.

CONTEXT: Heart conditions affect salt and water homeostasis as a consequence of the underlying condition, compensatory processes, and therapy, and can result in nocturnal polyuria. These processes need to be identified as part of a full evaluation of nocturia. OBJECTIVE: To conduct a systematic review of nocturia in cardiovascular disease and achieve expert consensus for primary care management. Primary care was defined as a health care setting in which the expertise did not include specialist cardiology. EVIDENCE ACQUISITION: Four databases were searched from January 2000 to April 2020. A total of 3524 titles and abstracts were screened and 27 studies underwent full-text screening. Of these, eight studies were included in the analysis. The nominal group technique (NGT) was used to achieve consensus among an expert panel incorporating public involvement. EVIDENCE SYNTHESIS: Most studies focused on nocturia related to blood pressure (BP), while one investigated leg oedema. Hypertension, particularly overnight blood pressure above normal, corresponds with higher risk of nocturia. NGT identified fluid and salt overload, nondipping hypertension, and some therapeutic interventions as key nocturia contributors. History taking and examination should identify raised jugular venous pressure/ankle swelling, with relevant investigations including measurement of BP, resting electrocardiogram, and B-type natriuretic peptide. Treatment recommends reducing salt (including substitutes), alcohol and caffeine. Heart failure is managed according to local guidance and controlling fluid intake to 1-2 l daily. If there is no fluid retention, reduce or discontinue diuretics or calcium channel blockers and follow up to reassess the condition. The target clinic blood pressure is 140/90 mm Hg. CONCLUSIONS: Cardiovascular disease and its treatment are influential for understanding nocturia. Management aims to identify and treat heart failure and/or hypertension. PATIENT SUMMARY: People with cardiovascular disease can suffer severe sleep disturbance because of a need to pass urine at night due to increased overnight blood pressure or heart failure. Following a detailed evaluation of the published research, a group of experts recommended practical approaches for assessing and treating these issues.

Case report: The art of anesthesiology-Approaching a minor procedure in a child with MPI-CDG.

Background: Protein glycosylation plays an important role in post-translational modification, which defines a broad spectrum of protein functions. Accordingly, infants with a congenital disorder of glycosylation (CDG) can have N-glycosylation, O-glycosylation, or combined N- and O-glycosylation defects, resulting in similar but different multisystem involvement. CDGs can present notable gastrointestinal and neurologic symptoms. Both protein-losing enteropathy and hypotonia affect the decision of using anesthetics. We reported a case of MPI-CDG with protein-losing enteropathy and muscular hypotonia that underwent different anesthesia approach strategies of vascular access. Here, we highlight why intubation with sevoflurane anesthesia and sparing use of muscle relaxants is the optimal strategy for such a condition. Case presentation: A 25-month-old girl, weighing 6.6 kg and 64 cm tall, suffered chronic diarrhea, hypoalbuminemia, and hypotonia since birth. Protein-losing enteropathy due to MPI-CDG was documented by whole-exome sequencing. She underwent three sedated surgical procedures in our hospital. The sedation was administered twice by pediatricians with oral chloral hydrate, intravenous midazolam, and ketamine, to which the patient showed moderate to late recovery from sedation and irritability the following night. The most recent one was administered by an anesthesiologist, where endotracheal intubation was performed with sevoflurane as the main anesthetic. The patient regained consciousness immediately after the operation. She had no complications after all three sedation/anesthesia interventions and was discharged 7 days later, uneventful after the third general anesthesia procedure. Conclusion: We performed safe anesthetic management in a 25-month-old girl with MPI-CDG using sevoflurane under controlled ventilation. She awoke immediately after the procedure. Due to the disease entity, we suggested bypassing the intravenous route to avoid excess volume for drug administration and that muscle relaxant may not be necessary for endotracheal intubation and patient immobilization when performing procedures under general anesthesia in CDG patients.

Safe Practice of Total Intravenous Anesthesia With Target-Controlled Infusion in Taiwan: A Recommendation.

There have been immense advances in the safety and variety of intravenous anesthetic delivery systems including drug cost reduction, development of more effective opioids, and improvement in depth of anesthesia monitoring in the last 20 years. Propofol-based total intravenous anesthesia (TIVA) with target-controlled infusion (TCI) is relatively easy to practice. While this technique promotes a higher overall anesthesia quality and patient survival, especially for cancer patients, there are deficiencies in training and education of the technique. Therefore, the Society for Intravenous Anesthesia and the Association of Anesthetists (United Kingdom) have laid out guidelines in an attempt to highlight multiple important TIVA-related safety issues to help clinicians feel more confident. In the present article, we discuss five recommendations and four special clinical situations. Preparation, equipment familiarity, and safe delivery techniques are extremely important for the proper employment of this method. Herein, we emphasize the importance of proper education, and the clinical practice experience of the TIVA technique. Additionally, we suggest a modified connection method to set up a safely administered line. We highlight the advantages of using processed electroencephalogram monitoring (such as bispectral index or Entropy) to prevent awareness during TIVA administration in difficult clinical situations. These situations may include triple low patients (e.g., low blood pressure, low maintained effect-site concentration of propofol, and low body weight ≤ 18), obese patients, and patients with difficult infusion site monitoring or use of neuromuscular blocking agents. Due to a limited consensus among Taiwanese medical professionals, this document is intended to act as a safe practice reference for the use of TIVA with TCI. Additionally, two pithy formula codes, 4321 for propofol with fentanyl/alfentanil and 42222111 for propofol with remifentanil, are provided for the general population and one pithy formula code, 4321 for propofol with fentanyl, is provided for pediatric patients.

Detection and Evaluation of Serological Biomarkers to Predict Osteoarthritis in Anterior Cruciate Ligament Transection Combined Medial Meniscectomy Rat Model.

Biomarkers are essential tools in osteoarthritis (OA) research, clinical trials, and drug development. Detecting and evaluating biomarkers in OA research can open new avenues for researching and developing new therapeutics. In the present report, we have explored the serological detection of various osteoarthritis-related biomarkers in the preclinical model of OA. In this surgical OA model, we disrupted the medial tibial cartilage's integrity via anterior cruciate ligament transection combined with medial meniscectomy (ACLT+MMx) of a single joint of Wistar rats. The progression of OA was verified, as shown by the microscopic deterioration of cartilage and the increasing cartilage degeneration scoring from 4 to 12 weeks postsurgery. The concentration of serological biomarkers was measured at two timepoints, along with the complete blood count and bone electrolytes, with biochemical analysis further conducted. The panel evaluated inflammatory biomarkers, bone/cartilage biomarkers, and lipid metabolic pathway biomarkers. In chronic OA rats, we found a significant reduction of total vitamin D3 and C-telopeptide fragments of type II (CTX-II) levels in the serum as compared to sham-operated rats. In contrast, the serological levels of adiponectin, leptin, and matrix metallopeptidase (MMP3) were significantly enhanced in chronic OA rats. The inflammatory markers, blood cell composition, and biochemical profile remained unchanged after surgery. In conclusion, we found that a preclinical model of single-joint OA with significant deterioration of the cartilage can lead to serological changes to the cartilage and metabolic-related biomarkers without alteration of the systemic blood and biochemical profile. Thus, this biomarker profile provides a new tool for diagnostic/therapeutic assessment in OA scientific research.

Teneligliptin Exerts Antinociceptive Effects in Rat Model of Partial Sciatic Nerve Transection Induced Neuropathic Pain.

Neuropathic pain (NP), is a chronic pain resulting from nerve injury, with limited treatment options. Teneligliptin (TEN) is a dipeptidyl peptidase-4 inhibitor (DPP-4i) approved to treat type 2 diabetes. DPP-4is prevent the degradation of the incretin hormone glucagon-like peptide 1 (GLP-1) and prolong its circulation. Apart from glycemic control, GLP-1 is known to have antinociceptive and anti-inflammatory effects. Herein, we investigated the antinociceptive properties of TEN on acute pain, and partial sciatic nerve transection (PSNT)-induced NP in Wistar rats. Seven days post PSNT, allodynia and hyperalgesia were confirmed as NP, and intrathecal (i.t) catheters were implanted and connected to an osmotic pump for the vehicle (1 µL/h) or TEN (5 µg/1 µL/h) or TEN (5 µg) + GLP-1R antagonist Exendin-3 (9-39) amide (EXE) 0.1 µg/1 µL/h infusion. The tail-flick response, mechanical allodynia, and thermal hyperalgesia were measured for 7 more days. On day 14, the dorsal horn was harvested and used for Western blotting and immunofluorescence assays. The results showed that TEN had mild antinociceptive effects against acute pain but remarkable analgesic effects against NP. Furthermore, co-infusion of GLP-1R antagonist EXE with TEN partially reversed allodynia but not tail-flick latency. Immunofluorescence examination of the spinal cord revealed that TEN decreased the immunoreactivity of glial fibrillary acidic protein (GFAP). Taken together, our findings suggest that TEN is efficient in attenuation of PSNT-induced NP. Hence, the pleiotropic effects of TEN open a new avenue for NP management.
