This study sets out to identify potential daily antecedents and consequences of pain-related activity avoidance and engagement behavior in adolescents with chronic pain.
Learn More >To develop a multicenter, multistakeholder, prospective clinical registry of children and adolescents with migraine to support the collection of real-world data of sufficient quality to support regulatory submissions and provide site-based infrastructure support for future clinical trials.
Learn More >To compare the effectiveness of deep tissue massage, supervised strengthening and stretching exercises, and a combined therapy (exercise followed by massage) (index groups), with advice to stay active (control group).
Learn More >This study sought to determine if pre- to post-treatment changes in pain-related activity patterns (i.e., overdoing, avoidance, and pacing) were associated with pre- to post-treatment changes in function (i.e., pain interference, psychological function, and physical function) in patients with fibromyalgia syndrome who participated in either an operant learning- or an energy conservation-based training in activity management.
Learn More >The amygdala is central to emotional processing of sensory stimuli, including pain. Because recent findings suggest that individual differences in emotional processes play a part in the development of chronic pain, a better understanding of the individual patterns of functional connectivity that make individuals susceptible to emotionally modulated facilitation of pain is needed. We therefore investigated the neural correlates of individual differences in emotional pain facilitation using resting-state functional magnetic resonance imaging (rs-fMRI) with amygdala seed.Thirty-seven participants took part in 3 separate sessions, during which pain sensitivity was tested (session 1), participants underwent rs-fMRI (session 2), and emotional pain modulation was assessed (session 3). Amygdala served as seed for the rs-fMRI analysis and whole-brain voxelwise connectivity was tested. Pain modulatory scores were entered as regressor for the group analysis.Stronger connectivity of the amygdala to S1/M1, S2/operculum, and posterior parietal cortex at rest characterized individuals who showed greater pain facilitation by negative emotions. When comparing the amygdala networks associated with pain unpleasantness and with pain intensity modulation, most of the identified areas were equally related to either pain rating type; only amygdala connectivity to S1/M1 was found to predict pain intensity modulation specifically.We demonstrate that trait-like patterns of functional connectivity between amygdala and cortical regions involved in sensory and motor responses are associated with the individual amplitude of pain facilitation by negative emotional states. Our results are an early step towards improved understanding of the mechanisms that give rise to individual differences in emotional pain modulation.
Learn More >Periodontitis (PD) and chronic migraine (CM) have been recently linked, and inflammatory processes and vascular endothelial changes are hypothesized as potential mediators of this relationship. The aim of this cross-sectional analysis was to investigate the potential association of PD with vascular systemic inflammation and complement activation in patients with CM.
Learn More >Insufficient perioperative pain treatment is known as a highly predictive risk factor for the development of chronic postoperative pain. Remifentanil is an ultrashort-acting opioid that provides quick and efficient analgesia but is associated with the induction of opioid-induced hyperalgesia. Despite these well-known characteristics, this substance is being increasingly used in anesthesia and in a variety of medical fields, such as intensive-care medicine and obstetrics.The aim of our study was to reveal whether remifentanil influences postoperative pain, the requirement for postoperative analgesics, and requirement of antiemetics (as indirect indicator of postoperative nausea and vomiting (PONV), as well as the effects on time to extubation and length of stay in the postanesthesia care-unit (PACU) in daily clinical routine.From an electronic medical records database of 55,693 anesthesias, we analyzed data from all patients receiving intraabdominal surgery (visceral, gynecological and urological) under general anesthesia or combined general-epidural anesthesia by propensity score matching.The administration of remifentanil was associated with higher postoperative pain scores despite a higher requirement of postoperative analgesics. Additional epidural analgesia was not able to avoid this finding.The intraoperative use of remifentanil is associated with a deterioration of pain levels and postoperative analgesic requirement, wherefore the potential benefit of this substance seems to be outweighed by its potential disadvantages. Especially in operative procedures in which high postoperative pain scores are expected, the unreflective use should be critically questioned.
Learn More >Pain can interfere with the daily functioning of persons with multiple sclerosis (PwMS). Furthermore, beliefs about pain and activity engagement are reliably associated with persons' experience of chronic pain. This study aimed to explore the extent to which different aspects of PwMS' activity engagement is related to pain-related illness intrusiveness, and whether certain coping and support systems mediate that relationship.
Learn More >Fabry disease (FD) is an X-linked lysosomal storage disorder that leads to cellular globotriaosylceramide (Gb3) accumulation due to mutations in the gene encoding α-galactosidase A. Trigger-induced acral burning pain is an early FD symptom of unknown pathophysiology. We aimed at investigating the potential role of skin fibroblasts in nociceptor sensitization.
Learn More >Dyadic coping is a process of coping within couples that is intended not only to support the patient with chronic pain but also to maintain equilibrium in the relationship. This study aims to investigate the effect of patient-perceived and spouse-reported dyadic coping on both the patient and their partner's relationship quality and anxiety, stress, and depression over time.
