Randomized Controlled Trial
The Effect of Duloxetine on Mechanistic Pain Profiles, Cognitive Factors, and Clinical Pain in Patients with Painful Knee Osteoarthritis - A Randomized, Double-Blind, Placebo-Controlled, Crossover Study.
Duloxetine is indicated in the management of pain in osteoarthritis. Evidence suggests that duloxetine modulates central pain mechanisms and cognitive factors, and these factors are assumed contributing to the analgesic effect. This proof-of-mechanism, randomized, placebo-controlled, crossover, double-blinded trial evaluated the effect of duloxetine on quantitative sensory testing (QST), cognitive factors and clinical pain in patients with osteoarthritis and to predict the analgesic effect. ⋯ Duloxetine is proposed as a treatment for chronic pain. Pre-clinical trials suggest that duloxetine provides analgesia through modulation of descending pain inhibitory pathways or through improvements in cognitive factors. The current study demonstrates that pretreatment mechanistic pain profiling, cognitive factors and clinical pain can predict the analgesic effect of duloxetine and that only a subset of patients might benefit from duloxetine treatment.

Randomized Controlled Trial Multicenter Study
A randomized controlled trial on long-term effectiveness of a psychosocial aftercare program following pediatric chronic pain treatment: Who benefits the most?
For paediatric chronic pain patients, intensive interdisciplinary pain treatment (IIPT) is a well-established treatment. The treatment's short-term effectiveness can be improved by an additive psychosocial aftercare (PAC). However, neither the program's long-term effectiveness nor the patients in particular need have been investigated yet. ⋯ A psychosocial aftercare following paediatric IIPT leads to significantly better pain and emotional outcomes compared to treatment as usual up to 12 months after discharge, especially for patients with single parents.

Randomized Controlled Trial
Reframe the Pain: Divided Attention and Positive Memory Reframing to Reduce Needle Pain and Distress in Children - A Feasibility Randomized Controlled Trial.
Negative experiences of needle procedures in childhood can lead to medical avoidance and vaccine hesitancy into adulthood. We evaluated the feasibility of two new interventions provided by clinical nurses to reduce the negative impact of vaccinations: divided attention (DA) and positive memory reframing (PMR). ⋯ Protocol number ACTRN12618000687291 at ANZCTR.org.au SIGNIFICANCE: Two new nurse-led interventions to reduce negative impacts of vaccinations in children, divided attention and positive memory reframing, were feasible and may reduce needle-related fear. Nurses were able to deliver the interventions in various environments including non-clinical settings (schools). These interventions have potential to facilitate broader dissemination of vaccinations for children in a manner that minimizes distress.

Randomized Controlled Trial
Neuropathic-like pain symptoms in inflammatory hand osteoarthritis lower quality of life and may not decrease under prednisolone treatment.
Pain is common in hand osteoarthritis (OA) and multiple types may occur. We investigated the prevalence, associated patient characteristics, influence on health-related quality of life (HR-QoL) and response to anti-inflammatory treatment of neuropathic-like pain in inflammatory hand OA. ⋯ Pain is the dominant symptom in hand OA, with an unclear aetiology. In this study, we found that neuropathic-like pain may play a role in hand OA, that it showed associations with female sex, younger age and more comorbidities and that it lowered health-related quality of life in hand OA. Neuropathic-like pain in hand OA seems resistant to prednisolone therapy but did not seem to interfere with the treatment of inflammatory pain with prednisolone.
