Diagnostic uncertainty, the perception of a lack of or incorrect label to explain symptoms, has been reported by parents of youth with chronic pain. This study was the first to examine diagnostic uncertainty in both youth with chronic pain and their parents using qualitative methodology. Individual, face-to-face, semi-structured interviews were conducted with twenty youth with chronic pain recruited from a pediatric chronic pain program. Independent interviews were also conducted with one of their parents. Interviews explored participants' memories and perceptions around diagnosis. In-depth thematic analysis revealed four themes: (1) The Function of a Diagnosis. Parents and youth struggled with the meaning of the diagnosis, needed further explanation for the pain, and perceived the 'right' diagnosis (i.e., one that fit with their beliefs) as justification for the pain. (2) Haunted by Something Missing. Negative test results did not provide relief or counter the belief that something serious could have been missed by clinicians. (3) The Search for an Alternative Diagnosis. A search persisted for the 'right' diagnosis, particularly when a non-pharmacological treatment plan was provided. (4) Mistrust in the Medical System. Clinician communication and perceptions of clinicians' uncertainty impacted parent and youth 'buy in' to the diagnosis. Findings suggest that many youth with chronic pain and their parents experience diagnostic uncertainty, which is integrally tied to their past experiences with the medical system. Greater understanding of diagnostic uncertainty may help tailor how clinicians deliver diagnoses to achieve 'buy in', increase understanding of pain and diagnosis, and improve treatment response. Perspective: A major challenge that youth with chronic pain and their parents face is understanding the cause of the pain. Youth with chronic pain and their parents experience uncertainty about their diagnosis, which may be linked to their 'buy in' and treatment response.

Although there have been many studies on the link between chronic pain and suicidality, surprisingly little research has focused on resilience and recovery among those in chronic and disabling pain who have had suicidal thoughts. The objectives of this study were to identify the prevalence and correlates of recovery from suicidal thoughts among those in chronic pain. A secondary analysis of a nationally representative sample of Canadians in chronic and disabling pain who had ever had serious suicidal thoughts (N = 635) was conducted to identify the prevalence and characteristics of those who are no longer considering suicide. Data were drawn from the Canadian Community Health Survey-Mental Health. Three in five Canadians in chronic pain (63%) who had seriously considered suicide at some point in their life had been free of these thoughts in the past year. Those free of suicidal ideation were significantly more likely to be older, women, white, better educated, with a confidant, and to use spirituality to cope, but less likely to have low household incomes, difficulties meeting basic expenses, and a history of depression and anxiety disorders. PERSPECTIVE: Almost two-thirds of formerly suicidal Canadians with chronic pain were free from suicidal thoughts in the past year. These findings provide a hopeful message of resilience and recovery in the context of disabling pain and help to improve targeted outreach to those most at risk for unremitting suicidality.

Fibromyalgia (FM) is a chronic syndrome characterized by widespread musculoskeletal pain, and physical and emotional symptoms. Although its pathophysiology is largely unknown, immune-inflammatory pathways may be involved. We examined serum interleukin (IL)-6, high sensitivity C-reactive protein (hs-CRP), CXCL-8, and IL-10 in 67 female FM patients and 35 healthy women while adjusting for age, body mass index (BMI), and comorbid disorders. We scored the Fibromyalgia Severity Score, Widespread Pain Index (WPI), Symptom Severity Scale (SSS), Hospital Anxiety (HADS-A), and Depression Scale and the Perceived Stress Scale (PSS-10). Clinical rating scales were significantly higher in FM patients than in controls. After adjusting for covariates, IL-6, IL-10, and CXCL-8 were lower in FM than in HC, whereas hs-CRP did not show any difference. Binary regression analyses showed that the diagnosis FM was associated with lowered IL-10, quality of sleep, aerobic activities, and increased HADS-A and comorbidities. Neural networks showed that WPI was best predicted by quality of sleep, PSS-10, HADS-A, and the cytokines, while SSS was best predicted by PSS-10, HADS-A, and IL-10. Lowered levels of cytokines are associated with FM independently from confounders. Lowered IL-6 and IL-10 signaling may play a role in the pathophysiology of FM.

The neurobiology of persistent pain shares common underlying psychobiology with that of traumatic stress. Modern treatments for traumatic stress often involve bottom-up sensorimotor retraining/exposure therapies, where breath, movement, balance and mindfulness, are used to target underlying psychobiology. Vigorous exercise, in particular Bikram yoga, combines many of these sensorimotor/exposure therapeutic features. However, there is very little research investigating the feasibility and efficacy of such treatments for targeting the underlying psychobiology of persistent pain.

Low back pain (LBP) is the leading cause of disability globally and its costs exceed those of cancer and diabetes combined. Recent evidence suggests that individualised cognitive and movement rehabilitation combined with lifestyle advice (cognitive functional therapy (CFT)) may produce larger and more sustained effects than traditional approaches, and movement sensor biofeedback may enhance outcomes. Therefore, this three-arm randomised controlled trial (RCT) aims to compare the clinical effectiveness and economic efficiency of individualised CFT delivered with or without movement sensor biofeedback, with usual care for patients with chronic, disabling LBP.

Prognostic screening of people with low back pain (LBP) improves utilisation of primary healthcare resources. Whether this also applies to secondary healthcare remains unclear. Therefore, this study aims to develop prognostic models to determine at baseline which patients with persistent LBP are likely to have a good and poor outcome to a 5-week programme of combined education and exercise ('UPLIFT') delivered in a secondary healthcare setting.
