Learn More >There is currently an emphasis on the biopsychosocial concept of pain in pain therapy programs. However, the complexity of chronic pain, in particular its importance for those affected by it, can only be insufficiently captured with this concept. This is due to the fact that, to date, one core aspect of the phenomenon chronic pain has only rarely been taken into account: its existential character. Chronic pain can threaten the self-image and the individual's understanding of the world, their wishes and goals in life, and ultimately the entire integrity of those affected. Statements by chronic pain sufferers show that such pain always represents an existential experience and affects the person as a whole. Two aspects make this very clear: the existential despair of the pain on the one hand, as well as questions of meaning and reorientation on the other. Current treatment concepts, however, do not adequately consider the existential character of such challenges. Chronic pain should therefore always be perceived and treated from a holistic perspective. In this context, the aspects of recognizing its uniqueness, helping to express the pain and giving space to the experience are to be given special consideration in order to support chronic pain patients in dealing with their pain.
Learn More >Chronic pain extends from childhood to adulthood for many young people. The transition from pediatric to adult care is a critical, yet understudied, healthcare task facing young adults with chronic pain. The aims of this observational, sequential mixed methods study were to (1) document the healthcare transition status of young adults with chronic pain (Stage 1, quantitative aim), (2) examine young adults' perspectives of barriers and facilitators of healthcare transition (Stage 2, qualitative aim), and (3) integrate findings to construct a theoretical framework of healthcare transition. A cohort was identified with childhood chronic pain and prior care in one of 15 multidisciplinary pediatric pain clinics across the United States and Canada. Approximately 6 years later, 189 young adults (M age = 21.0; age range = 18-24; 81.5% female) from this cohort with continuing chronic pain completed surveys for Stage 1, and a subsample (n = 17) completed qualitative interviews for Stage 2. Quantitative findings demonstrated that young adults may experience lapses in care, with 41.8% indicating they had not transitioned to adult pain services. Qualitative analysis revealed young adults experienced significant barriers (e.g., abrupt departure from pediatric care) as well as facilitators (e.g., acceptance of pain prognosis) of healthcare transition. Quantitative and qualitative findings were integrated to construct a healthcare transition framework for chronic pain, which highlights transition as a complex process involving multiple pathways, outcomes, and stakeholders. Advancements in research and practice are needed to develop transition services to bridge gaps in care and optimize health outcomes for young people with chronic pain. Perspective: This mixed-methods study demonstrated that 41.8% of young adults with chronic pain experience lapses in adult-centered pain care and identified key barriers and facilitators to successful healthcare transition. Findings were integrated to construct the first healthcare transition framework for youth with chronic pain.
Learn More >Chronic pain development is a frequent outcome of severe stressor exposure, with or without tissue injury. Enduring stress-induced hyperalgesia (ESIH) is believed to play a central role, but the precise mechanisms mediating the development of chronic posttraumatic pain, and the time-dependency of these mechanisms, remain poorly understood. Clinical and pre-clinical data suggest that the inhibition of FK506-binding protein 51 (FKBP51), a key stress system regulator, might prevent ESIH. We evaluated whether peritraumatic inhibition of FKBP51 in an animal model of traumatic stress exposure, the single prolonged stress (SPS) model, reversed ESIH evaluated via daily mechanical von Frey testing. FKBP51 inhibition was achieved using SAFit2, a potent and specific small molecule inhibitor of FKBP51, administered to male and female Sprague-Dawley rats via intraperitoneal injection. To assess timing effects, FKBP51 was administered at different times relative to stress (SPS) exposure. SAFit2 administration immediately after SPS produced a complete reversal in ESIH lasting >7d. In contrast, SAFit2 administration 72h following SPS produced only temporary hyperalgesia reversal, and administration 120h following SPS had no effect. Similarly, animals undergoing SPS together with tissue injury (plantar incision) receiving SAFit2 immediately post-surgery developed acute hyperalgesia but recovered by 4d and did not develop ESIH. These data suggest that (1) FKBP51 plays an important, time-dependent role in ESIH pathogenesis, (2) time windows of opportunity may exist to prevent ESIH via FKBP51 inhibition after traumatic stress, with or without tissue injury, and (3) the use of inhibitors of specific pathways may provide new insights into chronic post-traumatic pain development.
Learn More >The mechanisms underlying the transition from acute to chronic pain are unclear but may involve the persistence or strengthening of pain memories acquired in part through associative learning. Contextual cues, which comprise the environment in which events occur, were recently described as a critical regulator of pain memory; both male rodents and humans exhibit increased pain sensitivity in environments recently associated with a single painful experience. It is unknown, however, how repeated exposure to an acute painful unconditioned stimulus in a distinct context modifies pain sensitivity or the expectation of pain in that environment. To answer this question, we conditioned mice to associate distinct contexts with either repeated administration of a mild visceral pain stimulus (intraperitoneal injection of acetic acid) or vehicle injection over the course of three days. On the final day of experiments animals received either an acid injection or vehicle injection prior to being placed into both contexts. In this way, contextual control of pain sensitivity and pain expectation could be tested respectively. When re-exposed to the noxious stimulus in a familiar environment, both male and female mice exhibited context-dependent conditioned analgesia, a phenomenon mediated by endogenous opioid signaling. However, when expecting the presentation of a painful stimulus in a given context, males exhibited conditioned hypersensitivity whereas females exhibited endogenous opioid-mediated conditioned analgesia. These results are evidence that pain perception and engagement of endogenous opioid systems can be modified through their psychological association with environmental cues. Successful determination of the brain circuits involved in this sexually dimorphic anticipatory response may allow for the manipulation of pain memories, which may contribute to the development of chronic pain states.
Learn More >The concept of "invalidation" refers to the patient's perception that the social environment does not recognize their medical condition. This study explores and describes invalidation experiences among Swedish patients with chronic widespread pain with regard to sociodemographic and pain characteristics, impact of pain, self-reported health, and symptoms of anxiety and depressive. Methods: A cross-sectional design using questionnaires, including sociodemographic and pain variables, the Illness Invalidation Inventory (Likert scale items regarding 5 sources), the Hospital Anxiety and Depression Scale, and the Short-Form General Health Survey. Descriptive and univariate analyses were applied. Results: Of the 152 respondents, 91% were women. Swedish patients with chronic widespread pain experienced invalidation to a large extent from all sources. The highest scores for invalidation were reported from contacts with social services (68%), and the lowest from spouses (30%). Being younger (p < 0.006), having periodic pain (p = 0.011), and having had more frequent visits to a doctor in the previous year (p = 0.007) were characteristics associated with higher invalidation scores. Experiences of invalidation were associated with worse self-reported mental health scores (r = -0.29 to -0.46). Conclusion: Since patients with chronic widespread pain frequently experience invalidation from the social environment, this further challenge in daily life must be taken into consideration in pain management within multimodal pain rehabilitation.
