Comparison of fascia iliaca block with quadratus lumborum block for hip arthroplasty: A meta-analysis of randomized controlled trials

BACKGROUND

The efficacy of fascia iliaca block (FIB) versus quadratus lumborum block (QLB) remains controversial for pain management of hip arthroplasty. We conduct a systematic review and meta-analysis to explore the influence of FIB versus QLB on the postoperative pain intensity of hip arthroplasty.

METHODS

We have searched PubMed, EMbase, Web of Science, EBSCO, and Cochrane Library databases through July 2023 for randomized controlled trials assessing the effect of FIB versus QLB on pain control of hip arthroplasty. This meta-analysis is performed using the random-effect model or fixed-effect model based on the heterogeneity.

RESULTS

Four randomized controlled trials and 234 patients were included in the meta-analysis. Overall, compared with QLB for hip arthroscopy, FIB was associated with substantially lower pain scores at 2 hours (mean difference [MD] = -0.49; 95% CI = -0.63 to -0.35; P < .00001) and pain scores at 12 hours (MD = -0.81; 95% CI = -1.36 to -0.26; P = .004), but showed no impact on pain scores at 24 hours (MD = -0.21; 95% CI = -0.57 to 0.15; P = .25), time to first rescue analgesia (standard mean difference = 0.70; 95% CI = -0.59 to 1.99; P = .29), analgesic consumption (MD = -4.80; 95% CI = -16.57 to 6.97; P = .42), or nausea and vomiting (odd ratio = 0.66; 95% CI = 0.32-1.35; P = .25).

CONCLUSIONS

FIB may be better than QLB for pain control after hip arthroplasty, as evidenced by the lower pain scores at 2 and 24 hours.

Interactions and Trends of Interleukins, PAI-1, CRP, and TNF-α in Inflammatory Responses during the Perioperative Period of Joint Arthroplasty: Implications for Pain Management-A Narrative Review

Inflammation during the perioperative period of joint arthroplasty is a critical aspect of patient outcomes, influencing both the pathophysiology of pain and the healing process. This narrative review comprehensively evaluates the roles of specific cytokines and inflammatory biomarkers in this context and their implications for pain management. Inflammatory responses are initiated and propagated by cytokines, which are pivotal in the development of both acute and chronic postoperative pain. Pro-inflammatory cytokines play essential roles in up-regulating the inflammatory response, which, if not adequately controlled, leads to sustained pain and impaired tissue healing. Anti-inflammatory cytokines work to dampen inflammatory responses and promote resolution. Our discussion extends to the genetic and molecular influences on cytokine production, which influence pain perception and recovery rates post-surgery. Furthermore, the role of PAI-1 in modulating inflammation through its impact on the fibrinolytic system highlights its potential as a therapeutic target. The perioperative modulation of these cytokines through various analgesic and anesthetic techniques, including the fascia iliac compartment block, demonstrates a significant reduction in pain and inflammatory markers, thus underscoring the importance of targeted therapeutic strategies. Our analysis suggests that a nuanced understanding of the interplay between pro-inflammatory and anti-inflammatory cytokines is required. Future research should focus on individualized pain management strategies.

Mindfulness in the Clinic Waiting Room May Decrease Pain: Results from Three Pilot Randomized Controlled Trials

Introduction: Mindfulness interventions can improve a broad range of patient outcomes, but traditional mindfulness-based interventions are time and resource intensive. Emerging evidence indicates brief, single-session mindfulness interventions can also improve patient outcomes, and brief mindfulness interventions can be embedded into medical care pathways with minimal disruption. However, the direct impact of a brief mindfulness intervention on patients' pain while waiting in the clinic waiting room remains unexamined. Objective: A series of three, pilot, randomized controlled trials (RCTs) were conducted to examine the impact of a brief, audio-recorded, mindfulness intervention on patients' pain in the clinic waiting room. Method: Study 1 examined an 8-min mindfulness recording delivered before a provider visit; Study 2 examined a 5-min mindfulness recording after a provider visit; and Study 3 examined a 4-min mindfulness recording before a provider visit. Time- and attention-matched control conditions were used in each study. Studies 1 and 2 were conducted in an academic cancer hospital. Study 3 was conducted at a walk-in orthopedic clinic. Pain intensity was measured in each of the three studies. Anxiety and depression symptoms were measured in Studies 2 and 3. Pain unpleasantness was measured in Study 3. Results: A brief (i.e., 4- to 8-min), audio-recorded mindfulness intervention decreased patients' pain intensity in the clinic waiting room, whether delivered before (Study 1 Cohen's d=1.01, Study 3 Cohen's d=0.39) or after (Study 2 Cohen's d=0.89) a provider visit. Mindfulness had a significant effect on anxiety symptoms in both studies in which it was measured. No effect on depression symptoms was observed. Conclusions: Results from these three pilot RCTs indicate brief, audio-recorded, mindfulness interventions may be capable of quickly decreasing clinical symptoms. As such, embedding brief, audio-recorded, mindfulness interventions in clinic waiting rooms may have the potential to improve patient outcomes. The continued investigation of this intervention approach is needed. Clinical Trial Registrations: NCT04477278 and NCT06099964.

The Effects of WeChat-Based Teach-Back Health Education on Patients With Advanced Cancer Pain

BACKGROUND

Providing effective health education is essential for patients with cancer-related pain. One solution is leveraging instant messaging tools for teach-back health education.

OBJECTIVES

This study investigated the effects of WeChat-based teach-back health education on patients with advanced cancer who underwent patient-controlled intrathecal analgesia implantation and used hydromorphone.

METHODS

This retrospective study evaluated 150 hospitalized patients with advanced cancer pain. Patients were classified into a conventional health education group (N = 50) and a teach-back group (N = 100) based on whether they received WeChat-based teach-back health education. Pain was rated using a numeric rating scale, and sleep quality was measured using the Pittsburgh Sleep Quality Index at one, two, and three months postdischarge.

FINDINGS

Patients who received remote teach-back health education better managed their pain. Data also demonstrated improvements in patients' sleep quality and caregiver satisfaction, and reductions in the occurrence of adverse reactions.

Uterine Fibroid Embolization Survey in Canada: Challenges, Opportunities, and Differences in Practices Across the Country

Purpose: To assess the current practices surrounding Uterine Fibroid Embolization (UFE) in Canada. Methods: An online survey was sent to Canadian Association for Interventional Radiology (CAIR) members. It included questions on symptoms prompting UFE, patient awareness, investigation, UFE settings, the number of UFE procedures, and post-UFE care. The findings were discussed at CAIR's 2023 annual meeting by an expert panel. Results: Out of 792 surveys sent, 87 were filled (11%). Menorrhagia is the most common indication for UFE (87%). Women's awareness of UFE as a treatment option for fibroids is viewed as poor or average by 94% of our survey respondents. Most respondents see patients in clinics (92%) before the procedure and evaluate fibroids with MRI pre-UFE (76%). There is variability in care post-UFE, with 33% of procedures being performed as day surgery while 67% lead to overnight stay. For pain management, intravenous analgesia (including patient-controlled analgesia) is used in 76% (63/83) of cases while 19% (16/83) of respondents mentioned using epidural analgesia. Finally, there is an even split between embolic agent used; non-spherical polyvinyl alcohol (50%) and spherical particles (50%). Conclusion: Respondents believe patients in Canada still have limited awareness of UFE. Interventional radiologists are increasingly involved in the entire patient care trajectory, overseeing pre-and post-procedure care and hospitalizing patients. For pain management after UFE, it is observed that while epidural analgesia has been demonstrated more effective than alternatives, it is not widely used as the primary method.

Knowledge, attitudes, and current practices toward lung cancer palliative care management in China: a national survey

Scope

The present investigation seeks to illuminate the current state and disparities in the knowledge, attitudes, and practices (KAP) among healthcare professionals regarding the management of lung cancer palliative care (LCPC) in China, while simultaneously assessing the prevalence and context of patient-controlled analgesia (PCA) usage in the management of cancer-related pain.

Methods

A total of 2093 healthcare practitioners from 706 hospitals across China completed a structured questionnaire that probed various facets of LCPC management. The questionnaire consisted of seven thematic sections, incorporating chi-square tests and Fisher's exact probabilities to statistically assess the discrepancies in KAP among healthcare professionals across different hospital grades. Ordered data distributions among hospital grades were compared using non-parametric Kruskal-Wallis H and Mann-Whitney U tests. Multiple-choice items were subjected to multiple-response cross-tabulation analysis, while the Spearman rank-order correlation coefficient was employed to gauge potential associations among variables.

Results

Around 84.2% of the respondents perceived anti-tumor therapy to be of equal importance to palliative care. Statistically significant differences (χ² = 27.402, P = 0.002) in satisfaction levels were observed, with participants from Tertiary hospitals demonstrating higher satisfaction compared to those from Secondary and Primary hospitals. Pain emerged as the most prevalent symptom necessitating LCPC. Major impediments to LCPC adoption included patients' and families' concerns about the safety of long-term palliative care-related drug use. 31.1% of the respondents cited the most frequent rationale for PCA use as cases involving patients who required systemic administration of large opioid doses or exhibited intolerable adverse reactions to opioids. The principal deterrents against the use of PCA for cancer pain management were (1): apprehension about adverse drug reactions due to overdose (2), concern about the potential for opioid addiction, and (3) the anticipated increase in patients' economic burdens. Over the preceding 24-month period, 33.9% of the surveyed healthcare practitioners reported no engagement in either online or offline LCPC-related training initiatives.

Conclusion

This study emphasizes the pressing need for comprehensive training in LCPC among Chinese health personnels, particularly focusing on the effective management of cancer pain symptoms.

Low back pain management in primary healthcare: findings from a scoping review on models of care

INTRODUCTION

Models of care (MoCs) describe evidence-informed healthcare that should be delivered to patients. Several MoCs have been implemented for low back pain (LBP) to reduce evidence-to-practice gaps and increase the effectiveness and sustainability of healthcare services.

OBJECTIVE

To synthesise research evidence regarding core characteristics and key common elements of MoCs implemented in primary healthcare for the management of LBP.

DESIGN

Scoping review.

DATA SOURCES

Searches on MEDLINE (PubMed), EMBASE, Cochrane Central Register of Controlled Trials, PEDro, Scopus, Web of Science and grey literature databases were conducted.

ELIGIBILITY CRITERIA

Eligible records included MoCs implemented for adult LBP patients in primary healthcare settings.

DATA EXTRACTION AND SYNTHESIS

Data extraction was carried out independently by two researchers and included a summary of the studies, the identification of the MoCs and respective key elements, concerning levels of care, settings, health professionals involved, type of care delivered and core components of the interventions. Findings were investigated through a descriptive qualitative content analysis using a deductive approach.

RESULTS

29 studies reporting 11 MoCs were included. All MoCs were implemented in high-income countries and had clear objectives. Ten MoCs included a stratified care approach. The assessment of LBP patients typically occurred in primary healthcare while care delivery usually took place in community-based settings or outpatient clinics. Care provided by general practitioners and physiotherapists was reported in all MoCs. Education (n=10) and exercise (n=9) were the most common health interventions. However, intervention content, follow-ups and discharge criteria were not fully reported.

CONCLUSIONS

This study examines the features of MoCs for LBP, highlighting that research is in its early stages and stressing the need for better reporting to fill gaps in care delivery and implementation. This knowledge is crucial for researchers, clinicians and decision-makers in assessing the applicability and transferability of MoCs to primary healthcare settings.

Buprenorphine Use for Analgesia in Palliative Care

Buprenorphine is a semi-synthetic long-acting partial µ-opioid receptor (MOR) agonist that can be used for chronic pain as a sublingual tablet, transdermal patch (Butrans®), or a buccal film (Belbuca®). Buprenorphine's unique high receptor binding affinity and slow dissociation at the MOR allow for effective analgesia while offering less adverse effects compared to a full agonist opioid, in particular, less concern for respiratory depression and constipation. It is underused in chronic pain and palliative care due to misconceptions and stigma from its use in opioid use disorder (OUD). This case report discusses the unique pharmacology of buprenorphine, including its advantages, disadvantages, available formulations, drug-drug interactions, initiation and conversion strategies, and identifies ideal populations for use, especially within the palliative care patient population.

Intercostal Catheters Reduce Long-Term Pain and Postoperative Opioid Consumption after VATS

Background/Objectives: Pain after video-assisted thoracoscopic surgery (VATS) leads to impaired postoperative recovery, possible side effects of opioid usage, and higher rates of chronic post-surgery pain (CPSP). Nevertheless, guidelines on perioperative pain management for VATS patients are lacking. The aim of this study was to analyze the effectiveness of intercostal catheters in combination with a single shot intraoperative intercostal nerve block (SSINB) in comparison to SSINB alone with respect to opioid consumption and CPSP. Methods: Patients receiving an anatomic VATS resection between 2019 and 2022 for primary lung cancer were retrospectively analyzed. A total of 75 consecutive patients receiving an ICC and SSINB and 75 consecutive patients receiving only SSINB were included in our database. After enforcing the exclusion criteria (insufficient documentation, external follow-ups, or patients receiving opioids on a fixed schedule; n = 9) 141 patients remained for further analysis. Results: The ICC and No ICC cohort were comparable in age, gender distribution, tumor location and hospital stay. Patients in the ICC cohort showed significantly less opioid usage regarding the extent (4.48 ± 6.69 SD vs. 7.23 ± 7.55 SD mg, p = 0.023), duration (0.76 ± 0.97 SD vs. 1.26 ± 1.33 SD days, p = 0.012) and frequency (0.90 ± 1.34 SD vs. 1.45 ± 1.51 SD times, p = 0.023) in comparison to the No ICC group. During the first nine months of oncological follow-up assessments, no statistical difference was found in the rate of patients experiencing postoperative pain, although a trend towards less pain in the ICC cohort was found. One year after surgery, the ICC cohort expressed significantly less often pain (1.5 vs. 10.8%, p = 0.035). Conclusions: Placement of an ICC provides VATS patients with improved postoperative pain relief resulting in a reduced frequency of required opioid administration, less days with opioids, and a reduced total amount of opioids consumed. Furthermore, ICC patients have significantly lower rates of CPSP one year after surgery.

GFAP palmitoylcation mediated by ZDHHC23 in spinal astrocytes contributes to the development of neuropathic pain

BACKGROUND

Cancer pain has a significant impact on patient's quality of life. Astrocytes play an important role in cancer pain signaling. The direct targeting of astrocytes can effectively suppress cancer pain, however, they can cause many side effects. Therefore, there is an urgent need to identify the specific signaling pathways or proteins involved within astrocytes in cancer pain as targets for treating pain.

METHODS

A neuropathic cancer pain (NCP) model was established by inoculating mouse S-180 sarcoma cells around the right sciatic nerve in C57BL/6 mice. Spontaneous persistent pain and paw withdrawal thresholds were measured using von Frey filaments. The NCP spinal cord dorsal horn (L4-L6) and mouse astrocyte cell line MA-C were used to study protein palmitoylation using acyl-biotin exchange, real-time polymerase chain reaction, ELISA, western blotting, and immunofluorescent staining.

RESULTS

In a cancer pain model, along with tumor growth, peripheral nerve tissue invasion, and cancer pain onset, astrocytes in the dorsal horn of the spinal cord were activated and palmitoyltransferase ZDHHC23 expression was upregulated, leading to increased palmitoylation levels of GFAP and increased secretion of inflammatory factors, such as (C-X-C motif) ligand (CXCL)10 (CXCL-10), interleukin 6, and granulocyte-macrophage colony-stimulating factor. These factors in turn activate astrocytes by activating the signal transducer and activator of transcription 3 (STAT3) signaling pathway. A competitive peptide targeting GFAP palmitoylations was designed to effectively alleviate morphine tolerance in cancer pain treatment as well as cancer pain signaling and inflammatory factor secretion.

CONCLUSIONS

In a rodent model, targeting GFAP palmitoylation appears to be an effective strategy in relieving cancer pain and morphine tolerance. Human translational research is warranted.

Hyperbaric bupivacaine versus prilocaine for spinal anesthesia combined with total intravenous anesthesia during oncological colon surgery in a 23-hour stay enhanced recovery protocol: A non-randomized study

After the success of the enhanced recovery after surgery protocol, perioperative care has been further optimized in accelerated enhanced recovery pathways (ERPs), where optimal pain management is crucial. Spinal anesthesia was introduced as adjunct to general anesthesia to reduce postoperative pain and facilitate mobility. This study aimed to determine which spinal anesthetic agent provides best pain relief in accelerated ERP for colon carcinoma. This single center study was a secondary analysis conducted among patients included in the aCcelerated 23-Hour erAS care for colon surgEry study who underwent elective laparoscopic colon surgery. The first 30 patients included received total intravenous anesthesia combined with spinal anesthesia with prilocaine, the 30 patients subsequently included received spinal anesthesia with hyperbaric bupivacaine. Primary endpoint of this study was the total amount of morphine milligram equivalents (MMEs) administered during hospital stay. Secondary outcomes were amounts of MMEs administered in the recovery room and surgical ward, pain score using the numeric rating scale, complication rates and length of hospital stay. Compared to prilocaine, the total amount of MMEs administered was significantly lower in the bupivacaine group (n = 60, 16.3 vs 6.3, P = .049). Also, the amount of MMEs administered and median pain scores were significantly lower after intrathecal bupivacaine in the recovery room (MMEs 11.0 vs 0.0, P = .012 and numeric rating scale 2.0 vs 1.5, P = .004). On the surgical ward, median MMEs administered, and pain scores were comparable. Postoperative outcomes were similar in both groups. Spinal anesthesia with hyperbaric bupivacaine was associated with less opioid use and better pain reduction immediately after surgery compared to prilocaine within an accelerated ERP for elective, oncological colon surgery.

A Scoping Review of the Effect of EEG Neurofeedback on Pain Complaints in Adults with Chronic Pain

Background and Aim: Non-pharmacological treatments such as electroencephalogram (EEG) neurofeedback have become more important in multidisciplinary approaches to treat chronic pain. The aim of this scoping review is to identify the literature on the effects of EEG neurofeedback in reducing pain complaints in adult chronic-pain patients and to elaborate on the neurophysiological rationale for using specific frequency bands as targets for EEG neurofeedback. Methods: A pre-registered scoping review was set up and reported following the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) extension for Scoping Reviews (PRISMA-ScR). The data were collected by searching for studies published between 1985 and January 2023 in PubMed, EMBASE, and PsycINFO. Results: Thirty-two studies on various types of chronic pain were included. The intervention was well-tolerated. Approximately half of the studies used a protocol that reinforced alpha or sensorimotor rhythms and suppressed theta or beta activity. However, the underlying neurophysiological rationale behind these specific frequency bands remains unclear. Conclusions: There are indications that neurofeedback in patients with chronic pain probably has short-term analgesic effects; however, the long-term effects are less clear. In order to draw more stable conclusions on the effectiveness of neurofeedback in chronic pain, additional research on the neurophysiological mechanisms of targeted frequency bands is definitely worthwhile. Several recommendations for setting up and evaluating the effect of neurofeedback protocols are suggested.

New perspectives on migraine treatment: a review of the mechanisms and effects of complementary and alternative therapies

Migraine is a prevalent and disabling neurovascular disorder, with women being more susceptible, characterized by unilateral throbbing headache, often accompanied by nausea and vomiting, and often associated with various comorbidities such as brain and cardiovascular diseases, which can have a serious impact on quality of life. Although nonsteroidal anti-inflammatory drugs (NSAIDs) are the main first-line medications for the treatment of pain, long-term use often leads to side effects and drug addiction, which emphasizes the need to investigate alternative pain management strategies with fewer adverse effects. Complementary and alternative medicine is a viable pain intervention often used in conjunction with traditional medications, including acupuncture, herbs, moxibustion, transcutaneous electrical stimulation, bio-supplements, and acupressure, which offer non-pharmacological alternatives that are now viable pain management options. This review focuses on the mechanistic doctrine of migraine generation and the role and potential mechanisms of Complementary and Alternative Therapies (CAT) in the treatment of migraine, summarizes the research evidences for CAT as an adjunct or alternative to conventional therapies for migraine, and focuses on the potential of novel migraine therapies (calcitonin gene-related peptide (CGRP) antagonists and pituitary adenylyl cyclase-activating peptide (PACAP) antagonists) with the aim of evaluating CAT therapies as adjunctive or alternative therapies to conventional migraine treatment, thereby providing a broader perspective on migraine management and the design of treatment programs for more effective pain management.

Effectiveness of Virtual Reality in Reducing Perceived Pain and Anxiety Among Patients Within a Hospital System: Protocol for a Mixed Methods Study

BACKGROUND

Within hospital systems, diverse subsets of patients are subject to minimally invasive procedures that provide therapeutic relief and necessary health data that are often perceived as anxiogenic or painful. These feelings are particularly relevant to patients experiencing procedures where they are conscious and not sedated or placed under general anesthesia that renders them incapacitated. Pharmacologic pain management and topical anesthetic creams are used to manage these feelings; however, distraction-based methods can provide nonpharmacologic means to modify the painful experience and discomfort often associated with these procedures. Recent studies support distraction as a useful method for reducing anxiety and pain and as a result, improving patient experience. Virtual reality (VR) is an emerging technology that provides an immersive user experience and can operate through a distraction-based method to reduce the negative or painful experience often related to procedures where the patient is conscious. Given the possible short-term and long-term outcomes of poorly managed pain and enduring among patients, health care professionals are challenged to improve patient well-being during medically essential procedures.

OBJECTIVE

The purpose of this pilot project is to assess the efficacy of using VR as a distraction-based intervention for anxiety or pain management compared to other nonpharmacologic interventions in a variety of hospital settings, specifically in patients undergoing lumbar puncture procedures and bone marrow biopsies at the oncology ward, patients receiving nerve block for a broken bone at an anesthesia or surgical center, patients undergoing a cleaning at a dental clinic, patients conscious during an ablation procedure at a cardiology clinic, and patients awake during a kidney biopsy at a nephrology clinic. This will provide the framework for additional studies in other health care settings.

METHODS

In a single visit, patients eligible for the study will complete brief preprocedural and postprocedural questionnaires about their perceived fear, anxiety, and pain levels. During the procedure, research assistants will place a VR headset on the patient and the patient will undergo a VR experience to distract from any pain felt from the procedure. Participants' vitals, including blood pressure, heart rate, and rate of respiration, will also be recorded before, during, and after the procedure.

RESULTS

The study is already underway, and results support a decrease in perceived pain by 1.00 and a decrease in perceived anxiety by 0.3 compared to the control group (on a 10-point Likert scale). Among the VR intervention group, the average rating for comfort was 4.35 out of 5.

CONCLUSIONS

This study will provide greater insight into how patients' perception of anxiety and pain could potentially be altered. Furthermore, metrics related to the operational efficiency of providing a VR intervention compared to a control will provide insight into the feasibility and integration of such technologies in routine practice.

Evaluating the balance of benefits and harms in chronic pain clinical trials: prioritizing individual participants over individual outcomes

BACKGROUND

Randomized clinical trials (RCTs) generally assess efficacy and safety separately, with the conclusion of whether a treatment is beneficial based solely on the efficacy endpoint. However, assessing and combining efficacy and safety domains, using a single composite outcome measure, can provide a more comprehensive assessment of the overall effect of a treatment. Furthermore, composite outcomes can incorporate information regarding the relationship between the individual outcomes. In fact, such outcomes have been suggested in the clinical trials literature for at least 15 years.

OBJECTIVES

To (1) identify whether recent primary publications of chronic pain RCTs from major pain journals included a composite outcome measure of benefits and harms and (2) discuss the potential benefits of such outcomes in various stages of treatment development, including as outcome measures in RCTs, and to support decisions of Data and Safety Monitoring Boards and ordering of treatments in the context of treatment guidelines.

EVIDENCE REVIEW

RCTs published in 6 major pain journals published between 2016 and 2021 that investigated interventions for chronic pain were reviewed.

FINDINGS

Of 73 RCTs identified, only 2 included a composite outcome measure of benefits and harms. Both of these articles compared 2 active treatments.

CONCLUSIONS

Composite outcomes of benefits and harms are underutilized in chronic pain RCTs. The advantages and challenges of using such outcomes are discussed.

Evaluating the effectiveness of neurofeedback in chronic pain management: a narrative review

The prevalence and impact of chronic pain in individuals worldwide necessitate effective management strategies. This narrative review specifically aims to assess the effectiveness of neurofeedback, an emerging non-pharmacological intervention, on the management of chronic pain. The methodology adopted for this review involves a meticulous search across various scientific databases. The search was designed to capture a broad range of studies related to neurofeedback and chronic pain management. To ensure the quality and relevance of the included studies, strict inclusion and exclusion criteria were applied. These criteria focused on the study design, population, intervention type, and reported outcomes. The review synthesizes the findings from a diverse array of studies, including randomized controlled trials, observational studies, and case reports. Key aspects evaluated include the types of neurofeedback used (such as EEG biofeedback), the various chronic pain conditions addressed (like fibromyalgia, neuropathic pain, and migraines), and the methodologies employed in these studies. The review highlights the underlying mechanisms by which neurofeedback may influence pain perception and management, exploring theories related to neural plasticity, pain modulation, and psychological factors. The results of the review reveal a positive correlation between neurofeedback interventions and improved pain management. Several studies report significant reductions on pain intensity, improved quality of life, and decreased reliance on medication following neurofeedback therapy. The review also notes variations in the effectiveness of different neurofeedback protocols and individual responses to treatment. Despite the promising results, the conclusion of the review emphasizes the need for further research. It calls for larger, well-designed clinical trials to validate the findings, to understand the long-term implications of neurofeedback therapy, and to optimize treatment protocols for individual patients.

Patterns of anatomical injury and anaesthesia procedures in wounded Ukrainian soldiers from Anti-Terrorist Operation/Operation Joint Forces: 2014-2021

INTRODUCTION

The study aims to analyse the causes and anatomical patterns of explosive and gunshot wounds in Ukrainian soldiers acquired during the Anti-Terrorist Operation/Operation Joint Forces. We also investigated how general and regional anaesthesia procedures affected post-operative pain in wounded soldiers.

METHODS

A retrospective observational study was done based on the medical records of Ukrainian soldiers wounded in the Anti-Terrorist Operation/Operation Joint Forces between 2014 and 2021. The collected data included the American Society of Anesthesiologists score, mechanism of injury, the pattern of anatomical injury, pain intensity and the choice of anaesthesia given. Pain intensity was diagnosed using a Numerical Rating Scale.

RESULTS

A total of 280 combat casualties with explosive (75.7%) and gunshot (24.3%) wound injuries were included in the study. Most of the wounded soldiers had one body region affected by injury (59.3%). In most of the cases, the affected body regions were lower (48.2%) and upper (33.8%) limbs. In 62.5% of patients, regional anaesthesia was used, while general anaesthesia was used in 37.5% of cases. The pain significantly decreased after initial treatment at the field medical unit regardless of the anaesthesia type or the number of affected body regions.

CONCLUSION

Understanding the sources and anatomical patterns of war-related injuries in recent conflicts is an important element in reducing the mortality and suffering of wounded soldiers. The high percentage of injured extremities in our cohort emphasises the importance of regional anaesthesia in contemporary wars.

Research priorities in regional anaesthesia: where should we focus?

Using a modified Delphi technique, an international group of regional anaesthetists generated a list of top research priorities in regional anaesthesia. The list of unanswered research questions was created from a questionnaire completed by >500 anaesthetists and distilled into 11 priorities grouped into four themes: clinical practice and efficacy, pain management, technology and equipment, and training and assessment.

Promoting pain coping skills in haemophilia: A remote intervention integrating exercise and pain education

BACKGROUND

Chronic joint pain is a significant and widespread symptom in people with haemophilia (PWH). Despite medical advancements, effective pain management remains challenging.

AIM

This study presents an innovative approach that integrates remote physical exercises, pain neuroscience education, and coping strategies to address chronic pain in PWH.

METHODS

The remote intervention consisted of sixteen 5-min videos encompassing physical exercises for chronic pain management and pain education strategies. These videos formed an 8-week remote intervention program. Clinical and physical assessments were conducted before and after the intervention.

RESULTS

A total of thirty-one PWHs, with a median age of 34 years (ranging from 16 to 59 years), completed the remote intervention. The study revealed significant improvements in pain intensity, disability, and physical performance among PWH with chronic pain. Enhanced functional capacity was evident in the Timed Up and Go and Single Leg Stance tests, accompanied by improved scores on the Functional Independence Score in Haemophilia (FISH). Although lacking a control group, our findings are consistent with other successful exercise and pain education programs.

CONCLUSIONS

This innovative intervention holds promise for managing chronic pain in PWH, underscoring patient empowerment, education, and collaboration. Notably, our study stands out by uniquely combining pain education and coping strategies, bolstering evidence for effective pain management.

A perspective on a precision approach to pain in cancer; moving beyond opioid therapy

PURPOSE

Cancer-related pain is primarily treated with opioids which while effective can add significant patient burden due to side effects, associated stigma, and timely access. The purpose of this perspective discussion is to argue for a precision approach to pain in cancer based on a biopsychosocial and spiritual model which we argue can offer a higher quality of life while limiting opioid use.

CONCLUSIONS

Pain in cancer represents a heterogenous process with multiple contributing and modulating factors. Specific characterization of pain as either nociceptive, neuropathic, nociplastic, or mixed can allow for targeted treatments. Additional assessment of biopsychosocial and spiritual issues can elucidate further points of targeted intervention which can lead to overall greater pain control.

Chronic overlapping pain conditions increase the risk of long COVID features, regardless of acute COVID status

ABSTRACT

Chronic overlapping pain conditions (COPCs) refer to conditions that have similar central nervous system pathophysiologic mechanisms driving widespread pain as well as common comorbid symptoms such as fatigue and problems with sleep, memory, and mood. If COPCs predict the onset of long COVID, this could offer a valuable orientation for long COVID-related research and clinical care. This retrospective cohort study aimed to determine whether having a COPC predicts the onset of long COVID features using US electronic health records and 1:1 propensity score matching without replacement. The study cohorts included (1) people with acute COVID (n = 1,038,402), (2) people with acute influenza (n = 262,092), and (3) a noninfected cohort comprising people with a routine healthcare encounter (n = 1,081,593). Having a COPC increased the risk of long COVID features in all 3 study cohorts. Among those with COVID, having a pre-existing COPC increased the risk by 1.47 (95% CI = 1.46, 1.47). In the influenza cohort, COPCs increased the risk by 1.39 (95% CI = 1.38, 1.40). In the noninfected cohort, COPCs increased the risk by 1.57 (95% CI = 1.56, 1.59). These findings reinforce the likelihood that nociplastic mechanisms play a prominent role in long COVID. Recognizing that this ubiquitous nonspecific syndrome occurs frequently in the population can inform precision medicine therapies that avoid the pitfalls of viewing long COVID exclusively in the framework of postinfectious disease.

Palliative care tumor board: a narrative review and presentation of a novel conference to enhance collaboration and coordination of pain and symptom management for patients with advanced cancer

BACKGROUND AND OBJECTIVE

The World Health Organization endorses that palliative care has a significant impact on the outcomes of patients with cancer. Integration of palliative care into standard oncology practice has been shown to improve a variety of patient outcomes. In this article, we present our experience with the development of a palliative care tumor board.

METHODS

Starting in June 2021, we implemented a multidisciplinary palliative care and oncology tumor board focused on pain and symptom management. Complex cases were presented bimonthly. We retrospectively reviewed our experience. Data were collected on the attendees, the case presented, and the resultant therapeutic decisions made.

KEY CONTENT AND FINDINGS

Between June 2021 and September 2022, tumor board meetings were conducted in person and virtually. An average of twelve people attended, including physicians and nurse practitioners from the palliative care, oncology, interventional radiology, radiation oncology, psychiatry, pediatric palliative care, and physical medicine and rehab disciplines. There were 68 patients presented with the most frequently discussed cancer being breast cancer, followed by lung cancer. A total of 18 patients (26%) were referred for procedure, including 7 patients (10%) for radiation and 11 patients (16%) for interventional procedures, and 34 patients (50%) had medication changes as outcomes of the meeting.

CONCLUSIONS

The development of a biweekly palliative care conference modeled after traditional oncologic tumor board meetings allows patients to be discussed in a multidisciplinary setting and commonly results in changes in the management for pain and other cancer-related symptoms.

Gastrointestinal adverse effects associated with the use of intravenous oliceridine compared with intravenous hydromorphone or fentanyl in acute pain management utilizing adjusted indirect treatment comparison methods

Background: In the absence of head-to-head comparative data from randomized controlled trials, indirect treatment comparisons (ITCs) may be used to compare the relative effects of treatments versus a common comparator (either placebo or active treatment). For acute pain management, the effects of oliceridine have been compared in clinical trials to morphine but not to fentanyl or hydromorphone. Aim: To assess the comparative safety (specifically differences in the incidence of nausea, vomiting and opioid-induced respiratory depression [OIRD]) between oliceridine and relevant comparators (fentanyl and hydromorphone) through ITC analysis. Methods: A systematic literature review identified randomized clinical trials with oliceridine versus morphine and morphine versus fentanyl or hydromorphone. The ITC utilized the common active comparator, morphine, for the analysis. Results: A total of six randomized controlled trials (oliceridine - 2; hydromorphone - 3; fentanyl - 1) were identified for data to be used in the ITC analyses. The oliceridine data were reported in two studies (plastic surgery and orthopedic surgery) and were also reported in a pooled analysis. The ITC focused on nausea and vomiting due to limited data for OIRD. When oliceridine was compared with hydromorphone in the ITC analysis, oliceridine significantly reduced the incidence of nausea and/or vomiting requiring antiemetics compared with hydromorphone (both orthopedic surgery and pooled data), while results in plastic surgery were not statistically significant. When oliceridine was compared with hydromorphone utilizing data from Hong, the ITC only showed a trend toward reduced risk of nausea and vomiting with oliceridine that was not statistically significant across all three comparisons (orthopedic surgery, plastic surgery and combined). An ITC comparing oliceridine with a study of fentanyl utilizing the oliceridine orthopedic surgery data and combined orthopedic and plastic surgery data showed a trend toward reduced risk that was not statistically significant. Conclusion: In ITC analyses, oliceridine significantly reduced the incidence of nausea and/or vomiting or the need for antiemetics in orthopedic surgery compared with hydromorphone and a non-significant trend toward reduced risk versus fentanyl.

Pharmacokinetic evaluation of oral deracoxib in geese (Anser anser domesticus)

The integration of pain management in veterinary practice, driven by heightened animal welfare concerns, extends to avian species where subtle and nonspecific behavioral signs pose challenges. Given that safety concerns with classical NSAIDs highlight the need for more targeted alternatives in birds, this study explores the pharmacokinetic (PK) properties of Deracoxib (DX), a COX-2 selective NSAID approved for use in dogs, following a single oral administration in geese. Six healthy female geese received 4 mg/kg DX. Blood was drawn from the left wing vein to heparinized tubes at 0, 0.25, 0.5, 0.75, 1, 1.5, 2, 4, 6, 8, 10, and 24 h. Plasma DX concentrations were measured using HPLC coupled to an UV detector, and the data were pharmacokinetically analyzed using PKanalix™ software in a non-compartmental approach. The results indicated a terminal half-life of 6.3 h and a Tmax of 1 h, with no observed adverse effects. While refraining from claiming absolute safety based on a single dose, it is worth highlighting that further safety studies for DX in geese are warranted, suggesting a possibility for intermittent use. In addition, drawing conclusions on efficacy and suitability awaits further research, particularly in understanding COX-2 selectivity and protein binding characteristics specific to geese.
