The aim of this paper was to investigate the role of economic (e.g. GDP per capita), political (e.g. healthcare spending), cultural (country-level aggregates norms) and individual correlates (e.g., depression) of pain in a secondary analysis of a sample of 76,000 adults in 19 countries across Europe. The sample was aggregated from two waves of the SHARE cohort, using multilevel models with cross-level interactions between individual and country-level effects. While there has been extensive focus on individual risk factors (e...

Intensive interdisciplinary pain treatments (IIPT) have been developed to treat youth with unmanaged chronic pain and functional disability. Dysregulation of metabolites gamma-aminobutyric acid (GABA) and glutamate are thought to play a role in the chronification of pain due to imbalances in inhibition and excitation in adults. Using magnetic resonance spectroscopy (MRS), we investigated the effect of IIPT on GABA and Glx (glutamate + glutamine) in 2 pain-related brain regions: the left posterior insula (LPI) and the anterior cingulate cortex (ACC)...

Over 20 million adults in the United States live with High Impact Chronic Pain (HICP), or chronic pain that limits life or work activities for ≥3 months. It is critically important to differentiate people with HICP from those who sustain normal activities although experiencing chronic pain. Therefore, we aim to help clinicians and researchers identify those with HICP by: (1) developing models that identify factors associated with HICP using the 2016 National Health Interview Survey (NHIS) and (2) evaluating the performances of those models overall and by sociodemographic subgroups (sex, age, and race/ethnicity)...

When the source of nociception expands across a body area, the experience of pain increases due to the spatial integration of nociceptive information. This well-established effect is called spatial summation of pain (SSp) and has been the subject of multiple investigations. Here, we used cold-induced SSp to investigate the effect of attention on the spatial tuning of nociceptive processing. Forty pain-free volunteers (N=40, 20 females) participated in this experiment. They took part in an SSp paradigm based on three hand immersions into cold water (5°C): Participants either immersed the radial segment ("a"), ulnar segment ("b") or both hand segments ("a+b") and provided overall pain ratings...

Traumatic brain injury (TBI) survivors often experience debilitating consequences. Due to the high impact nature of TBI, patients often experience concomitant peripheral injuries (i.e., polytrauma). A common, yet often overlooked, comorbidity of TBI is chronic pain. Therefore, this study investigated how common concomitant peripheral injuries (i.e., femoral fracture and muscle crush) can affect long-term behavioral and structural TBI outcomes with a particular focus on nociception. Rats were randomly assigned to one of four groups: polytrauma (POLY; i...

Exploring the relationship between nociplastic pain and the severity and impact of pelvic pain symptoms could lend insight into the heterogeneous symptom presentation and treatment response that complicates management of chronic pelvic pain. In this prospective cross-sectional study, we sought to evaluate relationships between degree of nociplastic pain, measured by the Fibromyalgia (FM) Survey Score, and multiple aspects of the chronic pelvic pain (CPP) experience, including severity, frequency, tenderness during pelvic myofascial exam, interference with daily life, and high-impact pain...

Vulvodynia, impacts up to 8% of women by age 40, and is hypothesized to manifest through an altered immune-inflammatory response. To test this hypothesis, we identified all women born in Sweden between 1973-1996 diagnosed with localized provoked vulvodynia (N76.3) and/or vaginismus (N94.2 or F52.5) between 2001 and 2018. We matched each case to two women from the same birth year with no vulvar pain ICD codes. As a proxy for immune dysfunction, we used Swedish Registry data to capture a) immunodeficiencies, b) single organ and multiorgan autoimmune conditions, c) allergy and atopies, and d) malignancies involving immune cells across the life course...

Cognitive behavioral therapy (CBT), acceptance and commitment therapy (ACT), and mindfulness-based stress reduction (MBSR) have demonstrated effectiveness for improving outcomes in chronic pain. These evidence-based psychotherapies (EBPs) remain underutilized in clinical practice, however. To identify research gaps and next steps for improving uptake of EBPs, we conducted a systematic review of patient-, provider-, and system-level barriers and facilitators of their use for chronic pain. We searched MEDLINE, Embase, PsycINFO, and CINAHL databases databases from inception through September 2022...

Although combining computational modeling with event-related potentials (ERPs) can precisely characterize neurocognitive processes involved in attention bias, it has yet to be applied in the context of pain. Here, a hierarchical drift-diffusion model (DDM) along with ERPs was used to characterize the neurocognitive mechanisms underlying attention bias towards pain. A spatial cueing paradigm was adopted, in which the locations of targets were either validly or invalidly predicted by spatial cues related to pain or non-pain signals...

Chronic posttraumatic musculoskeletal pain (CPTP) is a common outcome of traumatic stress exposure. Biological factors that influence the development of CPTP are poorly understood, though current evidence indicates that the hypothalamic-pituitary-adrenal (HPA) axis plays a critical role in its development. Little is known about molecular mechanisms underlying this association, including epigenetic mechanisms. Here, we assessed whether peritraumatic DNA methylation levels at 248 CpG sites in HPA axis genes (FKBP5, NR3C1, CRH, CRHR1, CRHR2, CRHBP, POMC) predict CPTP and whether identified CPTP-associated methylation levels influence expression of those genes...

Explaining chronic pain to children and families can be challenging, particularly in the absence of an obvious physiologically identifiable cause for the child's pain. In addition to medical intervention, children and families may expect clinicians to provide clarity around the cause of pain. Such explanations are often provided by clinicians who have not received formal pain training. This qualitative study sought to explore the following question: What do pediatricians consider to be important when providing pain explanations to children and their parents? Using semi-structured interview methods, sixteen UK pediatricians were interviewed regarding their perceptions of explaining chronic pain to children and families in clinical settings...

Spinal cord stimulation (SCS) is a recommended therapy to treat failed back surgery syndrome (FBSS). A trial period is practised to enhance patient selection. However, its fundamental evidence is limited, especially concerning long-term benefit and therapy safety. We compared the long-term (5.3 ± 4.0 years) clinical outcome and therapy safety of a trialled and non-trialled implantation strategy, including multidimensional variables and pain intensity fluctuations over time. A multi-centre cohort analysis was performed in two comparable groups of FBSS patients...

Approximately half of patients with alcohol use disorder report pain and this can be severe during withdrawal. Many questions remain regarding the importance of biological sex, alcohol exposure paradigm, and stimulus modality to the severity of alcohol withdrawal-induced hyperalgesia. To examine the impact of sex and blood alcohol concentration on the time course of the development of mechanical and heat hyperalgesia, we characterized a mouse model of chronic alcohol withdrawal-induced pain in the presence or absence the alcohol dehydrogenase inhibitor, pyrazole...

A comprehensive understanding of pain memories requires consideration of risk and resilience factors across biopsychosocial domains. Previous research has typically focused on pain-related outcomes, largely ignoring the nature and context of pain memories. Using a multiple-method approach, this study explores the content and context of pain memories in adolescents and young adults with complex regional pain syndrome (CRPS). Recruited via social media and pain-related organizations, participants completed an autobiographical pain memory task...

Pain is a significant symptom experienced frequently by individuals with sickle cell disease (SCD). Pain management includes strategies such as oral rehydration, non-pharmacological therapies (e.g., massage, relaxation), and oral analgesics and opioids. Shared decision-making around pain management is emphasized repeatedly in recent guidelines; however, research is sparse regarding factors to be considered in shared decision-making approaches including the perceived risks and benefits of opioids. This qualitative descriptive study was conducted to explore perspectives of decision-making for opioid medications in SCD...

Ostracism (i.e., being ignored/ excluded) is a form of social adversity that powerfully impacts health and well-being. While laboratory research indicates that experimentally manipulated experiences of ostracism impact pain, findings have been mixed. Prior investigations have not considered moderating or main effects of individual histories of ostracism, and have been limited in the scope of their pain testing. In this study, participants without current pain reported lifetime experiences of ostracism prior to a laboratory visit where they were randomized to experience either a single episode of ostracism (i...

Higher sensitivity to pain is a common clinical symptom in postmenopausal females. The gut microbiota (GM) has recently been identified as participating in various pathophysiological processes and may change during menopause and contribute to multiple postmenopausal symptoms. Here, we investigated the possible correlation between GM alteration and allodynia in ovariectomized (OVX) mice. Results showed that OVX mice exhibited allodynia from 7 weeks after surgery compared with sham-operated (SHAM) mice by comparing pain-related behaviors...
