Chemical characterization of the essential oil from the leaves of Eugenia flavescens DC. (Myrtaceae) and its potential in the treatment of pain, inflammation, and ethanol- and ethanol/HCL-induced gastric ulcers in mice.

Eugenia flavescens is a species cultivated in Brazil for food purposes. Given the potential application of essential oils from plants of the genus Eugenia, this study was carried out to investigate the chemical composition, acute toxicity, antioxidant, antinociceptive, gastroprotective activities, and possible mechanisms of action of the essential oil from the leaves of E. flavescens (EOEf). The EOEf was extracted by hydrodistillation, and the chemical composition was obtained using gas chromatography-mass spectrometry. The antioxidant activity was evaluated, as well as the acute toxicity and the antinociceptive and anti-inflammatory effects in mice. In addition, the gastroprotective effect was investigated using an acute gastric lesion model, considering possible mechanisms of action. The major components found in the EOEf were guaiol (19.97%), germacrene B (12.53%), bicyclogermacrene (11.11%), and E-caryophyllene (7.53%). The EOEf did not cause signs of toxicity in the acute oral toxicity test and showed in vitro antioxidant activity with IC50 ranging from 247.29 to 472.39µg/mL in the tests ABTS and DPPH. In the nociceptive test, EOEf showed a 72.05% reduction in nociception at a dose of 100mg/kg. In evaluating the anti-inflammatory effect, the essential oil inhibited paw edema by 95.50% and 97.69% at doses of 50 and 100mg/kg. The results showed that EOEf has a gastroprotective effect, acting through the sulfhydryl compounds (-SH), nitric oxide (NO), and synthesis PGE2 pathways. The results suggested that EOEf is a promising source of constituents with antioxidant, antinociceptive, anti-inflammatory, and gastroprotective properties with application in the food and pharmaceutical industries.

Differentiation of Post-Polio Syndrome from Prior Poliomyelitis Sequela by Assessing Paraspinal Muscle Involvement in Magnetic Resonance Imaging.

Background/Objectives: Post-polio syndrome (PPS) affects former polio patients, manifesting decades after initial infection with progressive symptoms like pain, fatigue, and muscle weakness. Diagnosis relies on the clinical criteria and exclusion of other probable causes. The purpose of this study is to determine the scope and new diagnostic value of magnetic resonance imaging (MRI) in identifying muscle involvement in PPS and distinguishing it from prior poliomyelitis (PPM). Methods: This study was approved by the Koç University Ethics Committee with Approval No. 2023.409.IRB2.090. Electronic medical archives from two academic institutions were searched for records tagged with ICD code B-91 for poliomyelitis sequalae. The resulting search query of 291 records was manually sorted for PPS and PPM, medical history, clinical examination findings, and lumbar MR images down to 32 patients. Two independent radiologists evaluated the paraspinal musculature in the MRIs using the Mercuri scale. Inter-rater agreement, comparison of the paraspinal musculatures between groups, and their relationship to leg involvement were assessed with the resulting data. Results: Inter-rater agreement was found to be almost perfect across all muscles, except for the multifidus muscle. When clinical examination findings were included for these muscles, quadratus lumborum (QL) degradation was found in both right-side (p = 0.017) and left-side (p = 0.002) leg involvement. Conclusions: QL muscle deterioration may serve as a diagnostic marker for PPS, potentially guiding lumbar pain treatment through rehabilitation.

"Virtual reality fixed me": A case report of the use of virtual reality during intensive interdisciplinary pain treatment.

Virtual reality (VR) is an innovative technology with the potential to enhance treatment for children with chronic pain and functional symptoms. Currently, little is known about patients' experiences of VR in the setting of intensive interdisciplinary pain treatment (IIPT). This study aimed to better understand how patients engage with and benefit from VR. This case report focuses on a 12-year-old female with amplified musculoskeletal pain syndrome and comorbid functional neurological disorder receiving treatment in inpatient IIPT. VR was incorporated into physical/occupational and recreational therapy sessions. A semi-structured interview was completed one-month post-discharge. Qualitative analysis revealed three major themes: Process of Change (VR was unique/immersive, reduced pain focus, challenged skepticism, and changed pain perception), Efficacy (VR increased movement, supported transitioning from a wheelchair to walking independently, and increased confidence, excitement, and surprise), and Engagement (VR aided in acknowledging progress, increased camaraderie, was fun, and challenged patient to extend treatment goals made in VR to real life). Therapist observations of the benefits and barriers to using VR in treatment are described. Overall, this report indicates that VR may be a helpful tool to use with existing IIPT interventions to enhance patient engagement in treatment and improve functionaloutcomes.

Mechanism of gabapentinoid potentiation of opioid effects on cyclic AMP signaling in neuropathic pain

Over half of spinal cord injury (SCI) patients develop opioid-resistant chronic neuropathic pain. Safer alternatives to opioids for treatment of neuropathic pain are gabapentinoids (e.g., pregabalin and gabapentin). Clinically, gabapentinoids appear to amplify opioid effects, increasing analgesia and overdose-related adverse outcomes, but in vitro proof of this amplification and its mechanism are lacking. We previously showed that after SCI, sensitivity to opioids is reduced by fourfold to sixfold in rat sensory neurons. Here, we demonstrate that after injury, gabapentinoids restore normal sensitivity of opioid inhibition of cyclic AMP (cAMP) generation, while reducing nociceptor hyperexcitability by inhibiting voltage-gated calcium channels (VGCCs). Increasing intracellular Ca2+ or activation of L-type VGCCs (L-VGCCs) suffices to mimic SCI effects on opioid sensitivity, in a manner dependent on the activity of the Raf1 proto-oncogene, serine/threonine-protein kinase C-Raf, but independent of neuronal depolarization. Together, our results provide a mechanism for potentiation of opioid effects by gabapentinoids after injury, via reduction of calcium influx through L-VGCCs, and suggest that other inhibitors targeting these channels may similarly enhance opioid treatment of neuropathic pain.

Revisiting capsaicin and nonivamide: Their analogs exert strong inhibitory activity against cholinesterases

The scientific community has long been interested in capsaicin, and the extensive hunt for AChE and BChE enzyme inhibitors is still ongoing. In this investigation analogs of capsaicin, such as the pharmaceutical nonivamide, which is preferred in clinical settings for the topical treatment of pain, were explored in the search for appropriate inhibitors. Thus, to test their inhibitory effect on AChE and BChE, we synthesized a short series of derivatives derived from vanillylamide. Consequently, it was discovered that compounds 12, 34, and 35, which have Ki values in the sub-micromolar concentration range, are especially effective inhibitors. Compound 12 demonstrated dual mixed-type (competitive/uncompetitive) inhibitory activity for both enzymes; compound 34 showed selective mixed-type inhibitory activity for AChE, and compound 35 was found to have selective uncompetitive activity for AChE.

Postoperative Analgesic Regimens and Their Satisfaction Rates-Data from the Swedish Quality Register for Tonsil Surgery.

To describe postoperative analgesic regimens and patient-reported pain-related outcomes after tonsil surgery. Cohort study including perioperative data (n = 9274) and patient-reported outcome measures (n = 5080) registered in the Swedish Quality Register for Tonsil Surgery during 2023. After tonsil surgery, 92.7% received at least paracetamol and a NSAID/COX inhibitor, while 6.8% received no NSAID/COX inhibitor. Opioids were prescribed after tonsillectomy to 62.9% of adults and less often to adolescents and children (13-17-year-olds: 48.2%, 6-12-year-olds: 8.8%, 0-5-year-olds: 4.0%). Clonidine was frequently prescribed to 0-5-year-olds after tonsillectomy (54.4%). Overall, 11.7% reported dissatisfaction with the pain treatment, with the highest dissatisfaction rate after tonsillectomy in adolescents (20.6%) and adults (20.0%), and the lowest after tonsillotomy in children (4.9-6.8%). The most common complaint among dissatisfied patients was analgesics not being sufficiently helpful. Adult patients who received addition of opioids were less dissatisfied with the pain treatment (15.9% vs. 25.9%, p < 0.001), but also reported more side effects (5.7% vs. 2.7%, p = 0.039), compared with patients who received only paracetamol and NSAID/COX inhibitors. Tonsil surgery patients in Sweden receive various analgesic regimens. Although most are satisfied with pain treatment, there is room for improvement, particularly among adolescents and adults undergoing tonsillectomy. Paracetamol and a NSAID/COX inhibitor seem advisable as basic treatment. However, many patients need more effective treatment. The addition of opioids in adults results in greater satisfaction with pain treatment, but safety issues with opioid prescriptions must be taken into consideration. Level 4 Laryngoscope, 2024.

TMEM132C rs7296262 Single-Nucleotide Polymorphism Is Significantly Associated with Nausea Induced by Opioids Administered for Cancer Pain and Postoperative Pain.

Opioids are almost mandatorily used for analgesia for cancer pain and postoperative pain. Opioid analgesics commonly induce nausea as a side effect. However, the genetic factors involved are still mostly unknown. To clarify the genetic background of individual differences in the occurrence of nausea during opioid administration, the incidence of nausea was investigated in 331 patients (Higashi-Sapporo Hospital [HS] group) who received morphine chronically for cancer pain treatment and in 2021 patients (Cancer Institute Hospital [CIH] group) who underwent elective surgery under general anesthesia. We conducted a genome-wide association study of nausea in HS samples. Among the top 20 candidate single-nucleotide polymorphisms (SNPs), we focused on the TMEM132C rs7296262 SNP, which has been reportedly associated with psychiatric disorders. The rs7296262 SNP was significantly associated with nausea in both the HS and CIH groups (TT+TC vs. CC; HS group, p = 0.0001; CIH group, p = 0.0064). The distribution of nausea-prone genotypes for the rs7296262 SNP was reversed between HS and CIH groups. These results suggest that the TMEM132C rs7296262 SNP is significantly associated with nausea during opioid use, and the effect of the SNP genotype on nausea is reversed between chronic and acute phases of opioid use.

Pediatric Neural Changes to Physical and Emotional Pain After Intensive Interdisciplinary Pain Treatment

Objective: Brain areas activated during pain can contribute to enhancing or reducing the pain experience, showing a potential connection between chronic pain and the neural response to pain in adolescents and youth. Methods: This study examined changes in brain activation associated with experiencing physical pain, and the observation of physical and emotional pain in others, by using functional magnetic resonance imaging (fMRI) before and after intensive interdisciplinary pain treatment (IIPT). Eighteen youth (age 14 to 18) with widespread chronic pain completed fMRI testing before and after IIPT to assess changes in brain activation in response to physical and emotional pain. Results: Broadly, brain activation changes were observed in frontal, somatosensory, and limbic regions. These changes may suggest improvements in descending pain modulation via thalamus and caudate, and the different pattern of brain activation after treatment suggests potentially better discrimination between physical and emotional pain. Brain activation changes were also correlated with improvements in clinical outcomes of catastrophizing (reduced activation in right caudate, right mid-cingulate, and postcentral gyrus) and pain-related disability (increased activation in precentral gyrus, left hippocampus, right middle occipital cortex, and left superior frontal gyrus). Discussion: These changes could indicate that reduced brain protective responses to pain were associated with treatment-related improvements. This pilot study highlights the need for larger trials designed to better understand the brain mechanisms involved in pediatric widespread pain treatment.

The DECISION project: DiscrEte Choice experIment Spinal manipulative therapy for lOw back paiN: A study protocol

The smallest worthwhile effect (SWE) is the smallest beneficial effect of an intervention that justifies the costs, risks, and inconveniences. The objective is to establish the SWE of spinal manipulative therapy (SMT) for the treatment of low back pain (LBP), and to gain insight into how different attributes of the treatment are traded among each other when choosing SMT. Part 1. A mixed-methods study will be conducted to establish and prioritize a list of attributes influencing choices for those who consider SMT for the treatment of LBP. Individual interviews and consensus groups with chiropractors, manual therapists, and osteopaths and their patients will be conducted. Interviews and consensus groups will be voice-recorded and transcribed verbatim. Part 2. A Discrete Choice Experiment (DCE) will be conducted among people with LBP who have limited to no experience with SMT. Participants will be recruited through an online independent panel company. The survey will consist of several choice sets with attributes and their levels established from Part 1. The DCE will be preceded by a short survey to understand the clinical aspects (i.e. presentation, history and previous treatment for LBP) as well as socio-demographic characteristics of the participants.

Is there an association between pelvic pain and gender-affirming testosterone therapy in trans masculine adolescents? An exploratory cross-sectional study

Background High rates of pelvic pain have been reported in trans individuals on testosterone, but the pathophysiology of pain and the potential role of testosterone are unclear. Aims The aim of this exploratory study was to determine whether the proportion of pelvic pain in trans adolescents is different among those on testosterone therapy compared to those who are not. Secondary objectives were to determine the characteristics, potential contributing factors, impact, and treatment of pelvic pain in trans adolescents. Methods An online cross-sectional study about pelvic pain was conducted among trans individuals assigned female at birth, aged 12 and over, and who had sought care at our institution since 2017. Results Among 102 participants, 79 (77.5%) reported having experienced pelvic pain over the last 6 months. The proportion of individuals who reported pelvic pain was lower in individuals on testosterone (n = 43/62, 69.4%) compared to those not on testosterone (n = 36/40, 90%), with a difference in proportion of −20.6% (95% CI −35.4 to −5.9%, p = 0.006). Half of participants reported school or work absenteeism and two thirds missed extracurricular activities because of pelvic pain. A wide range of treatment options were used, with variable rates of reported effectiveness. Conclusion Pelvic pain is frequently reported by trans adolescents. This exploratory study found a lower proportion of pelvic pain in trans adolescents using testosterone therapy compared to those who were not. Nevertheless, this study was limited by a small number of participants, its cross-sectional nature, and the risk of recruitment bias, thus limiting its generalizability. Longitudinal studies are required to better understand the development and evolution of pelvic pain in trans adolescents.

Efficacy and safety of minodronate in the treatment of postmenopausal osteoporosis with low back pain: a single-centre, randomized and open-label controlled trial

BackgroundLow back pain is one of the most common symptoms of osteoporosis. The pain can seriously affect patients’ mood and quality of life; it can also further aggravate bone loss, causing a serious social burden. Minodronate is an oral bisphosphonate that needs to be administered daily. It significantly reduces levels of bone turnover markers (BTMs) and rapidly improves symptoms of low back pain in patients with osteoporosis. Osteoporosis requires long-term treatment, and daily dosing reduces patient compliance. Minodronate has a better safety profile than other bisphosphonates. The objective of the trial is to explore the efficacy and safety of minodronate in the treatment of low back pain in postmenopausal osteoporosis patients.MethodsThis is a single-centre, randomized, open-label controlled trial with a 24-week duration. Seventy-two eligible patients will be randomly divided into 4 groups. Subjects will be randomized at a 1:1 ratio to receive either minodronate (1 mg/day) or alendronate (10 mg/day) every day; senior women (≥ 75 years old) and older women (< 75 years old) will be at a ratio of 1:2. The primary outcome is the time required for the visual analogue scale (VAS) score to decline by ≥ 10 from baseline. The secondary outcome is the changes in VAS scores from baseline, the frequency and dosage of rescue medication, BTMs, bone mineral density (BMD), and variations in upper gastrointestinal (GI) symptom scores from baseline (including heartburn, pain, and bloating).DiscussionThis study will provide objective evidence for the efficiency and safety of minodronate. Furthermore, it will be helpful to evaluate the quantitative relationship between BTMs and BMD in patients with osteoporosis under different ages.Trial registrationThis study protocol has been registered with ClinicalTrials.gov ID NCT05645289 (https://clinicaltrials.gov/search?term=NCT05645289) on December 8, 2022. The registry name is Peking University Third Hospital. This study protocol was reviewed and approved by the Peking University Third Hospital Medical Science Research Ethics Committee (M2022465, 2022.08.09, V2.0). The results will be published in scientific peer-reviewed journals.Trial statusThe protocol was registered at ClinicalTrials.gov (registration number: NCT05645289). Recruitment has started in January 2023 and is still ongoing.

Mitigating and preventing perioperative opioid-related harm.

Although necessary for treatment of acute pain, opioids are associated with significant harm in the perioperative period and further intervention is necessary perioperatively to mitigate opioid-related harm. Opioid-naive patients are often first exposed to opioids when undergoing surgery, which can result in significant harm. Despite their benefits in reducing acute postsurgical pain, they are also associated with risks ranging from mild (e.g., pruritis, constipation, nausea) to potentially catastrophic (e.g. opioid-induced ventilatory impairment, respiratory depression, death). Overprescribing of opioids can lead to opioid diversion and drug driving. In this review, we will discuss opioid-related harm and what strategies can be used perioperatively to mitigate this harm. Interventions such as optimizing nonopioid analgesia, implementing Enhanced Recovery after Surgery programs, effective respiratory monitoring, patient education and opioid stewardship programs will be discussed. We will review policy and guidelines regarding perioperative opioid management and identify challenges and future directions to mitigate opioid-related harm.

Giving a Herbal Drink “Hot Ginger” to Relieve Menstrual Pain to Students at the Islamic Boarding School Kediri

Menstruation is a natural physiological change that occurs in every woman and is influenced by reproductive hormones, FSH (estrogen) or LH (progesterone). When you are menstruating, usually women will experience pain or cramps in the lower abdomen; this is called dysmenorrhea. One of the treatments for menstrual pain is traditional medicine using ginger ale. To analyze the effectiveness of giving ginger wedang to reduce the intensity of dysmenorrhea pain in female students in islamic boarding schools. This study uses a type of research. quasi-experimental, that is, with a one-group pretest-posttest design. With a population of students at the Islamic boarding school kediri as many as 86 students. The sampling was carried out by purposive sampling, so a sample of 31 respondents was obtained. Meanwhile, data analysis uses the Wilcoxon Signed Rank Test formula. The results showed that the intensity of dysmenorrhea on day 1 before being given ginger tea had most of the respondents on a pain scale of 7-9 with an average pain scale of 6.9, and after being given ginger tea on day 2, the pain intensity scale of most respondents decreased between 1- 3 with an average of 1.9. The results of the Wilcoxon Signed Rank Test obtained a significance value of 0.003. Giving wedang jahe during menstrual pain is believed to reduce the intensity of dysmenorrhea pain

Spinal Metastases of the Vertebrae: Three Main Categories of Pain.

Oncologic back pain, infection, inflammation, and trauma are the only specific etiologies of chronic low back pain (CLBP) in contrast to most patients who have non-specific CLBP. In oncologic patients developing CLBP, it is critically important to perform further investigation to exclude spinal metastases (SM).The incidence of cancer is increasing, with 15.7-30% developing SM. In the case of symptomatic SM, we can distinguish three main categories: tumor pain; mechanical pain due to instability, with or without pathologic fractures; and metastatic epidural spinal cord compression (MESCC) or radicular compression. Treatment of SM-related pain is dependent on these categories and consists of symptomatic treatment, target therapy to the bone, radiotherapy, systemic oncologic treatment, and surgery. The care for SM is a multidisciplinary concern, with rapid evolutions in all specialties involved. It is of primordial importance to incorporate the knowledge of specialists in all participating disciplines, such as oncology, radiotherapy, and spinal surgery, to determine the adequate treatment to preserve ambulatory function and quality of life while limiting the burden of treatment if possible. Awareness of potential SM is the first and most important step in the treatment of SM-related pain. Early diagnosis and timely treatment could prevent further deterioration. In this review, we explore the pathophysiology and symptomatology of SM and the treatment options for SM-related pain: tumor pain; mechanical pain due to instability, with or without pathologic fractures; and MESCC or radicular compression.

Reliability of the Biomechanical Assessment of the Sagittal Lumbar Spine and Pelvis on Radiographs Used in Clinical Practice: A Systematic Review of the Literature.

Background: Biomechanical analysis of the sagittal alignment of the lumbar spine and pelvis on radiographs is common in clinical practices including chiropractic, physical therapy, scoliosis-related thoraco-lumbo-sacral orthosis (TLSO) management, orthopedics, and neurosurgery. Of specific interest is the assessment of pelvic morphology and the relationship between angle of pelvic incidence, sacral slope, and lumbar lordosis to pain, disability, and clinical treatment of spine conditions. The current state of the literature on the reliability of common methods quantifying these parameters on radiographs is limited. Methods: The objective of this systematic review is to identify and review the available studies on the reliability of different methods of biomechanical analysis of sagittal lumbo-pelvic parameters used in clinical practice. Our review followed the recommendations of the preferred reporting items for systematic reviews and meta-analyses (PRISMA). The design of this systematic review was registered with PROSPERO (CRD42023379873). Results: The search strategy yielded a total of 2387 articles. A total of 1539 articles were screened after deduplication and exclusion by automation tools, leaving 473 full-text articles that were retrieved. After exclusion, 64 articles met the inclusion criteria. The preponderance of the evidence showed good to excellent reliability for biomechanical assessment of sagittal lumbo-pelvic spine alignment. Conclusions: The results of this systematic review of the literature show that sagittal radiographic analysis of spinal biomechanics and alignment of the human lumbo-pelvic spine is a reliable tool for aiding diagnosis and management in clinical settings.
