Enhancing orofacial pain relief: α-phellandrene complexed with hydroxypropyl-β-cyclodextrin mitigates orofacial nociception in rodents.

Orofacial pain affects 10-15% of adults and can severely impact quality of life. Despite ongoing treatment challenges, monoterpene alpha-phellandrene (PHE) shows potential therapeutic benefits. This study aimed to develop and evaluate an inclusion complex of PHE with hydroxypropyl-beta-cyclodextrin (PHE-HPβCD) for treating orofacial pain. The PHE-HPβCD complex was created using physical mixing and characterized by differential scanning calorimetry (DSC) and high-performance liquid chromatography (HPLC) to determine encapsulation efficiency. The complex exhibited a 70.45% encapsulation efficiency. Male Swiss mice were used in models of orofacial pain induced by formalin, cinnamaldehyde, glutamate, and corneal nociception by hypertonic saline. Additionally, cytokine levels (TNF-α and IL-1β) were measured in the upper lip tissue of mice subjected to the formalin model. Both PHE and PHE-HPβCD showed significant antinociceptive effects at a 50mg/kg dose during formalin-induced pain, reducing both neurogenic and inflammatory phases of pain. PHE-HPβCD also reduced TNF-α and IL-1β levels. For cinnamaldehyde and glutamate-induced nociception, both treatments reduced pain behavior, but only PHE-HPβCD decreased eye wipes in corneal nociception. These results suggest that PHE, especially in complexed form, alleviates orofacial pain by potentially modulating pain-related receptors (TRPA1 and TRPV1), mediators, like glutamate, and reducing pro-inflammatory cytokines. Further research is needed to explore the precise mechanisms of PHE in chronic orofacial pain models, but the study indicates promising avenues for new pain treatments.

Factors Associated with Suicidal Behavior in Adolescents: An Umbrella Review Using the Socio-Ecological Model.

Adolescent suicide is a critical social issue with profound and lasting individual and collective consequences. This umbrella review examines factors associated with adolescent suicidal behavior through the socioecological framework of prevention and seeks to identify gaps in the existing literature. The review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and included a comprehensive search of the of the Web of Science, Scopus, and Cochrane databases in both English and Spanish, covering the period from 2018 to 2024, using terms related to adolescence and suicidal behavior. Out of 6,138 articles identified, 37 met the quality criteria and were selected for analysis. The studies highlighted individual risk factors such as age, gender, belonging to ethnic or gender minorities, emotional disorders, self-destructive behavior, emotional regulation, and experience of physical or emotional pain. Interpersonal factors such as parental relationships, sexual abuse, social isolation, peer pressure, and loneliness were also found. However, the review revealed a worrying lack of studies on societal and community factors and a paucity of research focusing on protective factors. The study highlights the need to include factors related to the physical and social environments that influence health and behavior in future research, as well as to enhance the resources and strengths of adolescents.

Levodopa Impairs Lysosomal Function in Sensory Neurons In Vitro

Parkinson’s disease (PD) is the second-most common neurodegenerative disease worldwide. Patients are diagnosed based upon movement disorders, including bradykinesia, tremor and stiffness of movement. However, non-motor signs, including constipation, rapid eye movement sleep behavior disorder, smell deficits and pain are well recognized. Peripheral neuropathy is also increasingly recognized, as the vast majority of patients show reduced intraepidermal nerve fibers, and sensory nerve conduction and sensory function is also impaired. Many case studies in the literature show that high-dose levodopa may induce or exacerbate neuropathy in PD, which is thought to involve levodopa’s metabolism to homocysteine. Here, we treated primary cultures of dorsal root ganglia and a sensory neuronal cell line with levodopa to examine effects on cell morphology, mitochondrial content and physiology, and lysosomal function. High-dose levodopa reduced mitochondrial membrane potential. At concentrations observed in the patient, levodopa enhanced immunoreactivity to beta III tubulin. Critically, levodopa reduced lysosomal content and also reduced the proportion of lysosomes that were acidic, thereby impairing their function, whereas homocysteine tended to increase lysosome content. Levodopa is a critically important drug for the treatment of PD. However, our data suggest that at concentrations observed in the patient, it has deleterious effects on sensory neurons that are not related to homocysteine.

“Neuroinflammation”: does it have a role in chronic pain? Evidence from human imaging

Abstract Despite hundreds of studies demonstrating the involvement of neuron-glia-immune interactions in the establishment and/or maintenance of persistent pain behaviors in animals, the role (or even occurrence) of so-called “neuroinflammation” in human pain has been an object of contention for decades. Here, I present the results of multiple positron emission tomography (PET) studies measuring the levels of the 18 kDa translocator protein (TSPO), a putative neuroimmune marker, in individuals with various pain conditions. Overall, these studies suggest that brain TSPO PET signal: (1) is elevated, compared to healthy volunteers, in individuals with chronic low back pain (with additional elevations in spinal cord and neuroforamina), fibromyalgia, migraine and other conditions characterized by persistent pain; (2) has a spatial distribution exhibiting a degree of disorder specificity; (3) is parametrically linked to pain characteristics or comorbid symptoms (eg, nociplastic pain, fatigue, depression), as well as measures of brain function (ie, functional connectivity), in a regionally-specific manner. In this narrative, I also discuss important caveats to consider in the interpretation of this work (eg, regarding the cellular source of the signal and the complexities inherent in its acquisition and analysis). While the biological and clinical significance of these findings awaits further work, this emerging preclinical literature supports a role of neuron-glia-immune interactions as possible pathophysiological underpinnings of human chronic pain. Gaining a deeper understanding of the role of neuroimmune function in human pain would likely have important practical implications, possibly paving the way for novel interventions.

Separate anterior paraventricular thalamus projections differentially regulate sensory and affective aspects of pain

The experience of pain is complex, involving both sensory and affective components, yet the underlying neural mechanisms remain elusive. Here, we show that formalin-induced pain behaviors coincide with increased responses in glutamatergic neurons within the anterior paraventricular nucleus of the thalamus (PVA). Furthermore, we describe non-overlapping subpopulations of PVAVgluT2 neurons involved in sensory and affective pain processing, whose activity varies across different pain states. Activating PVA glutamatergic neurons is sufficient to induce mechanical hypersensitivity and aversion behaviors, whereas suppression ameliorates formalin-induced pain. Furthermore, we identify the segregation of PVAVgluT2 projections to the bed nucleus of the stria terminalis (BNST) and nucleus accumbens (NAc), each influencing specific aspects of pain-like behavior. This finding provides an important insight into the mechanism of distinct components of pain, highlighting the pivotal role of PVA in mediating different aspects of pain-like behavior with distinct circuits.

Regenerative Outcomes of Combining siCOL1A2 Hydrogel with Acupuncture in a Rat Model of Chronic Intervertebral Disc Degeneration

Intervertebral disc degeneration (IVDD) is a significant cause of chronic pain and disability, necessitating innovative therapeutic strategies. This study investigates the combined effect of a novel siCOL1A2-encapsulated hydrogel and acupuncture on IVDD in a rat model. We developed a hydrogel system, siCOL1A2-encapsulated G5-PBA hydrogel (siCOL1A2@G5-PBA@Gel), designed for sustained siRNA delivery to the degenerated discs and assessed its therapeutic efficacy alongside acupuncture treatment. Key inflammatory genes were identified through RNA-seq analysis, with COL1A2 highlighted as a crucial regulator of inflammatory responses in IVDD. Our in vivo experiments involved treating rats with hydrogel alone, acupuncture alone, and combining both. The treatments were evaluated through behavioral pain assessments, imaging techniques (X-ray and MRI), and histological analyses. Results indicated that the combination therapy significantly alleviated pain, reduced inflammation, and promoted disc regeneration more effectively than individual treatments. The hydrogel proved biocompatible and facilitated targeted gene silencing, while acupuncture enhanced therapeutic outcomes by improving local blood circulation and modulating inflammatory responses. These findings suggest that integrating siCOL1A2 hydrogel with acupuncture offers a promising approach to treating IVDD.

Histone modifications and Sp1 promote GPR160 expression in bone cancer pain within rodent models.

Bone cancer pain (BCP) affects ~70% of patients in advanced stages, primarily due to bone metastasis, presenting a substantial therapeutic challenge. Here, we profile orphan G protein-coupled receptors in the dorsal root ganglia (DRG) following tumor infiltration, and observe a notable increase in GPR160 expression. Elevated Gpr160 mRNA and protein levels persist from postoperative day 6 for over 18 days in the affected DRG, predominantly in small-diameter C-fiber type neurons specific to the tibia. Targeted interventions, including DRG microinjection of siRNA or AAV delivery, mitigate mechanical allodynia, cold, and heat hyperalgesia induced by the tumor. Tumor infiltration increases DRG neuron excitability in wild-type mice, but not in Gpr160 gene knockout mice. Tumor infiltration results in reduced H3K27me3 and increased H3K27ac modifications, enhanced binding of the transcription activator Sp1 to the Gpr160 gene promoter region, and induction of GPR160 expression. Modulating histone-modifying enzymes effectively alleviated pain behavior. Our study delineates a novel mechanism wherein elevated Sp1 levels facilitate Gpr160 gene transcription in nociceptive DRG neurons during BCP in rodents.

Cannabinoid hyperemesis syndrome: genetic susceptibility to toxic exposure.

Cannabinoid hyperemesis syndrome presents as a complex of symptoms and signs encompassing nausea, vomiting, abdominal pain, and hot water bathing behavior, most typically in a heavy cannabis user. Its presentation is frequently associated with hypothalamic-pituitary-adrenal axis activation with stress and weight loss. Recent investigation has identified five statistically significant mutations in patients distinct from those of frequent cannabis users who lack the symptoms, affecting the TRPV1 receptor, two dopamine genes, the cytochrome P450 2C9 enzyme that metabolizes tetrahydrocannabinol, and the adenosine triphosphate-binding cassette transporter. The syndrome is associated with escalating intake of high potency cannabis, or alternatively, other agonists of the cannabinoid-1 receptor including synthetic cannabinoids. Some patients develop environmental triggers in scents or foods that suggest classical conditioned responses. Various alternative "causes" are addressed and refuted in the text, including exposure to pesticides, neem oil or azadirachtin. Nosological confusion of cannabinoid hyperemesis syndrome has arisen with cyclic vomiting syndrome, whose presentation and pathophysiology are clearly distinct. The possible utilization of non-intoxicating antiemetic cannabis components in cannabis for treatment of cannabinoid hyperemesis syndrome is addressed, along with future research suggestions in relation to its genetic foundation and possible metabolomic signatures.

Pain resilience dimensions and regional gray matter volume as risk factors for poor outcomes of chronic pain: a prospective cohort study.

Pain resilience and regional gray matter volume (rGMV) are established correlates of adaptation to chronic pain within cross-sectional studies. Extending such work, this prospective cohort study tested the status of baseline pain resilience dimension scores and rGMV as risk factors for subsequent exacerbations in chronic pain disability and intensity. 142 adults with chronic musculoskeletal pain completed an initial assessment comprising a structural magnetic resonance imaging scan and self-report measures of cognitive/affective positivity and behavioral perseverance pain resilience dimensions, disability, pain intensity, and demographics. Disability and pain intensity were outcomes re-assessed at a 6-month follow-up. The impact of pain resilience dimension scores and identified rGMV sites on follow-up outcomes was examined after controlling for other baseline correlates of outcomes. Mediating effects of identified rGMV sites on pain resilience dimension-follow-up outcome relations were also evaluated. Aside from the significant multivariate effect of lower behavioral perseverance and cognitive/affective positivity scores, augmented left precuneus, temporal pole, superior temporal gyrus (STG), and precentral gyrus rGMV combined to predict higher follow-up disability levels, independent of covariates. Higher left fusiform gyrus rGMV levels predicted follow-up exacerbations in pain intensity, but pain resilience dimension scores did not. Finally, left precuneus and left temporal pole STG rGMV partially mediated cognitive/affective positivity-follow-up disability relations. Findings underscore deficits in pain resilience and increased rGMV as potential risk factors for poorer subsequent outcomes of chronic musculoskeletal pain and provide foundations for further prospective extensions as well as targeted intervention research.

Impact of low back pain and care-seeking behavior in an Indigenous community in Suriname: a qualitative approach.

Low back pain is a significant global public health issue affecting over half a billion people and contributing to disability worldwide. The impact of disability related to low back pain is growing, particularly in low- and middle-income countries. In contrast with previous research, current evidence shows Indigenous Peoples also experience low back pain's disabling effects. A clinical ethnographic can contribute by attempting to understand the data through the perspective of Indigenous Peoples. A clinical ethnographic study was conducted in Galibi, a Kalinya rural Indigenous village in Suriname, with support of the local traditional authority. The main objective was to explore the impact of low back pain and care-seeking behavior from the perspective of Indigenous Peoples with low back pain. The findings were that low back pain had a significant physical and emotional impact. Despite aggravating their low back pain, participants continued many of their activities of daily life since these were essential for their (economic) survival. Furthermore, participants expressed anxiousness, financial worries, and concerns about the cause and future of their low back pain. To address their low back pain, the Kalinya Indigenous Peoples used both western and traditional care. Visits to western healthcare practitioners were limited due to logistical challenges and travel costs, and the experience was often negative. The study highlights the experiences of Kalinya Indigenous Peoples dealing with low back pain. Low back pain is a burden within Indigenous Peoples of Galibi but accepted as an integral part of their life. When in pain, Indigenous Peoples face many barriers to access western health care and visits to healthcare practitioners were often unhelpful. This contributed to a long-lasting negative impact on the Indigenous people with low back pain. Further research is needed to develop strategies that improve health outcomes related to low back pain while reducing its associated disability in Indigenous Peoples.

Beneficial Effects of Ginger Root Extract on Pain Behaviors, Inflammation, and Mitochondrial Function in the Colon and Different Brain Regions of Male and Female Neuropathic Rats: A Gut-Brain Axis Study.

Neuroinflammation and mitochondrial dysfunction have been implicated in the progression of neuropathic pain (NP) but can be mitigated by supplementation with gingerol-enriched ginger (GEG). However, the exact benefits of GEG for each sex in treating neuroinflammation and mitochondrial homeostasis in different brain regions and the colon remain to be determined. Evaluate the effects of GEG on emotional/affective pain and spontaneous pain behaviors, neuroinflammation, as well as mitochondria homeostasis in the amygdala, frontal cortex, hippocampus, and colon of male and female rats in the spinal nerve ligation (SNL) NP model. One hundred rats (fifty males and fifty females) were randomly assigned to five groups: sham + vehicle, SNL + vehicle, and SNL with three different GEG doses (200, 400, and 600 mg/kg BW) for 5 weeks. A rat grimace scale and vocalizations were used to assess spontaneous and emotional/affective pain behaviors, respectively. mRNA gene and protein expression levels for tight junction protein, neuroinflammation, mitochondria homeostasis, and oxidative stress were measured in the amygdala, frontal cortex, hippocampus, and colon using qRT-PCR and Western blot (colon). GEG supplementation mitigated spontaneous pain in both male and female rats with NP while decreasing emotional/affective responses only in male NP rats. GEG supplementation increased intestinal integrity (claudin 3) and suppressed neuroinflammation [glial activation (GFAP, CD11b, IBA1) and inflammation (TNFα, NFκB, IL1β)] in the selected brain regions and colon of male and female NP rats. GEG supplementation improved mitochondrial homeostasis [increased biogenesis (TFAM, PGC1α), increased fission (FIS, DRP1), decreased fusion (MFN2, MFN1) and mitophagy (PINK1), and increased Complex III] in the selected brain regions and colon in both sexes. Some GEG dose-response effects in gene expression were observed in NP rats of both sexes. GEG supplementation decreased emotional/affective pain behaviors of males and females via improving gut integrity, suppressing neuroinflammation, and improving mitochondrial homeostasis in the amygdala, frontal cortex, hippocampus, and colon in both male and female SNL rats in an NP model, implicating the gut-brain axis in NP. Sex differences observed in the vocalizations assay may suggest different mechanisms of evoked NP responses in females.

Transformer-based classification of visceral pain-related local field potential patterns in the brain

Neuronal ensemble activity entrained by local field potential (LFP) patterns underlies a variety of brain functions, including emotion, cognition, and pain perception. Recent advances in machine learning approaches may enable more effective methods for analyzing LFP patterns across multiple brain areas than conventional time-frequency analysis. In this study, we tested the performance of two machine learning algorithms, AlexNet and the Transformer models, to classify LFP patterns in eight pain-related brain regions before and during acetic acid-induced visceral pain behaviors. Over short time windows lasting several seconds, applying AlexNet to LFP power datasets, but not to raw time-series LFP traces from multiple brain areas, successfully achieved superior classification performance compared with simple LFP power analysis. Furthermore, applying the Transformer directly to the raw LFP traces achieved significantly superior classification performance than AlexNet when using LFP power datasets. These results demonstrate the utility of the Transformer in the analysis of neurophysiological signals, and pave the way for its future applications in the decoding of more complex neuronal activity patterns.

Evaluating pain in non-verbal critical care patients: a narrative review of the critical care pain observation tool and Its clinical applications.

Assessing pain in critically ill patients who cannot communicate verbally poses significant challenges. Traditional self-report measures are ineffective for these patients, making the need for reliable observational tools crucial. To evaluate the effectiveness, reliability, and clinical applicability of the Critical Care Pain Observation Tool (CPOT) in various intensive care unit (ICU) settings and to explore potential innovations for improving its use and integration into clinical practice. A narrative review evaluated the Critical Care Pain Observation Tool (CPOT) for non-communicative ICU patients, comparing it to the Behavioral Pain Scale (BPS) and the FLACC scale. The review assessed CPOT's effectiveness across different ICU settings, identified limitations and challenges, and explored potential enhancements such as electronic scoring, additional physiological indicators, and improved training protocols. The CPOT has been validated as an effective pain assessment tool for non-verbal ICU patients. It evaluates pain through facial expressions, body movements, muscle tension, and ventilator compliance. The CPOT shows superior sensitivity at 76.5% compared to 62.7% for the BPS and offers a more comprehensive assessment of pain indicators like muscle tension and ventilator compliance than the FLACC scale. Despite its strengths, the CPOT has limitations, including inter-rater variability and challenges in certain patient populations. Barriers to implementation include resource constraints and the need for extensive training. The Critical Care Pain Observation Tool (CPOT) is a highly effective instrument for assessing pain in non-verbal ICU patients, demonstrating superior accuracy and reliability compared to other tools like the Behavioral Pain Scale (BPS) and FLACC scale. Its detailed approach, covering facial expressions, body movements, muscle tension, and ventilator compliance, offers a detailed measure of pain. However, challenges such as inter-rater variability and limitations in specific patient populations highlight the need for ongoing refinement and research.

Combined Transcranial Direct Current Stimulation and Pain Neuroscience Education for Chronic Low Back Pain: A Randomized Controlled Trial.

Priming the neural circuity likely targeted by pain neuroscience education (PNE), using transcranial direct current stimulation (tDCS) may enhance the efficacy of PNE. The aim of this study was to compare the effects of active tDCS + PNE to sham tDCS + PNE on measures of pain, pain behaviors, and cognitive function in participants with chronic low back pain (CLBP) and high pain catastrophizing. 20 participants were recruited and randomly allocated into the active tDCS + PNE (n = 10) or sham tDCS + PNE (n = 10) groups. All participants received five sessions of their assigned interventions over a 2-week period. The active tDCS + PNE group received 20 minutes of 2 mA, anodal current applied to the left dorsolateral prefrontal cortex. Within groups, both interventions demonstrated significant improvement in NPRS, PCS, and TSK. The active tDCS + PNE group also demonstrated significant improvement on the SCWT, CTMT2-Inhibitory, and CTMT2-Set Shifting. Between groups, the active tDCS + PNE group showed significantly greater improvement on the PCS, SCWT, and CTMT2-Inhibitory. The results of this pilot study suggest that active tDCS + PNE appeared to provide greater improvement than sham tDCS + PNE on levels of pain catastrophizing and attentional interference in participants with CLBP and high pain catastrophizing, consistent with both interventions targeting brain regions involved in those processes. Considering the differences between groups, tDCS appears to provide a priming effect on PNE.

Characteristics of patients with somatoform pain disorder

AbstractBackgroundPatients with somatoform pain experience physical pain that cannot be attributed to any underlying medical or physiological cause, and it is often thought to be related to psychological factors. Health professionals encounter difficulties identifying this specific type of chronic pain, leading to suboptimal treatment strategies. Therefore, we aimed to describe the characteristics of patients with somatoform pain, to support the identification of affected patients.MethodsWe collected and analyzed a cross‐sectional survey data from 200 patients with somatoform pain admitted to one of three psychosomatic centers in Germany between August 2013 and July 2014. The survey contains 10 different categories, all of them referring to pain‐related topics. Within the survey, we analyzed validated as well as non‐validated questionnaires. Here, we present the following five: Personal data, Body: Pain perception, Cognition: Pain processing, Pain behavior, and Physical complaints.ResultsOur results highlight that most patients with somatoform pain experience it in several body parts and as persisting, lasting >12 h/day (50%), and constantly changing (71%). Furthermore, patients indicate feelings of helplessness, by agreeing to the expressions the pain controls me (70%). Finally, we found that pain is predominantly seen as suffering, failing to convey emotional pain, despite cognitively acknowledging the dependency of emotional and physical pain.ConclusionThe study identified specific and distinctive characteristics in the emotional and behavioral responses of patients with somatoform pain, potentially distinguishing them from other patients with chronic pain.

The Effect of the Parent's Presence during the Dressing Process on the Severity of the Child's Pain

Objective: This research was carried out to determine the effect of the parent's presence near the child during the dressing process on the severity of pain caused by the dressing. Method: The sample of the descriptive comparative study consisted of 60 children. Ethics committee and study permission were obtained from the relevant institutions. Data were collected by observation and face-to-face interviews using the “Individual Characteristics Form” and the YBATT (facial expression, legs, activity, crying, and being able to be consoled) pain assessment scale Results: It was determined that the effect of the parent's presence with the child during the dressing on the severity of pain and behavioral pain symptoms was not statistically significant. In addition, it was determined that the gender (X2=0.071; p=0.500>0.05) and age (X2=6.133; p=0.105>0.05) of the children did not affect the perceived pain intensity in the presence or absence of parents. In the examination of the way parents support their children during the painful procedure, it was observed that 13 (43.4%) of them had a remote monitoring approach. Conclusion: In this study, it was seen that the presence of the parent with the child during the dressing did not affect the severity of the pain, the presence of the parent extended the dressing time, and the parents were in the approach of remote monitoring as a way of supporting the child during the procedure.

Slack potassium channels in spinal dorsal horn neurons control neuropathic pain and acute itch.

The sodium-activated potassium channel Slack (KNa1.1, Kcnt1) plays a critical role in tuning neuronal excitability. Previous studies have revealed that Slack is expressed in neurons of the superficial dorsal horn of the spinal cord. However, the precise role of Slack in spinal dorsal horn neurons is unclear. In this study, we used mice in which Slack is conditionally ablated in spinal dorsal horn neurons (Lbx1-Slack-/- mice) and analyzed their behaviors in various models of pain and itch. Lbx1-Slack-/- mice exhibited increased neuropathic pain behavior after peripheral nerve injury but normal responses in a model of inflammatory pain. Unexpectedly, Lbx1-Slack-/- mice demonstrated increased scratching after intradermal injection of chloroquine, LY344864, and histamine. Moreover, neuromedin B receptors are coexpressed with Slack in the dorsal horn, and scratching after intrathecal delivery of neuromedin B was increased in Lbx1-Slack-/- mice. Our study provides in vivo evidence that Slack expressed in spinal dorsal horn neurons inhibits nerve injury-induced allodynia and acute itch induced by various pruritogens.

Targeting chronic pain care to rural women veterans: A feasibility pilot.

For rural women veterans, significant barriers exist in accessing high-quality, multicomponent behavioral pain self-management interventions. As such, a telehealth behavioral pain self-management intervention designed specifically for rural-dwelling women veterans with chronic pain was piloted for this study. This mixed methods, single-arm preliminary study examined the feasibility and acceptability of this intervention and completed a responder analysis. Participants completed surveys before and 1-month following the intervention, and they completed a qualitative interview following the intervention. About one quarter (24%) of potentially eligible participants who were sent a letter about the study consented to participate (N = 44). All participants identified as female and were rural dwelling, with mean age of 56 years (range = 34-80), and the majority of the sample (81%) self-identified as White and non-Hispanic or Latino. Average baseline scores on the Pain, Enjoyment of Life, and General Activity three-item scale (PEG-3) measure indicated severe pain and functional interference (MPEG-3 total = 6.88, SD = 1.62). Of the 44 participants who consented, 70% completed the intervention. About half of treatment completers (47%, 14/30) were deemed responders, reporting ≥ 30% reduction on their PEG-3 total scores. On the Global Impression of Change scale, 87% reported improvement. Study completers indicated that the telehealth platform facilitated their engagement and that they perceived the intervention to be beneficial and credible. Qualitative data emphasized themes of connection with other women veterans who experienced chronic pain while perceiving a retained sense of individual identity. These preliminary data support feasibly of this intervention for rural-dwelling women veterans with chronic pain. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
