Information-processing biases such as attentional, interpretation, and memory biases are believed to play a role in exacerbating and maintaining chronic pain (CP). Evidence suggests that individuals with CP show attentional bias toward pain-related information. However, the selective attentional processes that underpin this bias are not always well outlined in the literature. ⋯ However, variation across studies did not allow for a decisive conclusion about the role of stimulus, task type, or related attentional processes. In addition, a table of CP attention-related models was produced and tested for reliability. Finally, other results and recommendations are discussed.

Transcutaneous electrical nerve stimulation (TENS) is a nonpharmacological modality widely used to manage pain; however, its effectiveness for individuals with fibromyalgia (FM) has been questioned. In previous studies and systematic reviews, variables related to dose of TENS application have not been considered. The objectives of this meta-analysis were (1) to determine the effect of TENS on pain in individuals with FM and (2) determine the dose-dependent effect of TENS dose parameters on pain relief in individuals with FM. ⋯ The electrode placement was not significantly associated with any effect sizes. Thus, there is evidence that TENS can effectively reduce pain in individuals with FM when applied at high or at mixed frequencies, a high intensity, or in long-term interventions involving 10 or more sessions. This review protocol was registered at PROSPERO (CRD42021252113).

Randomized Controlled Trial
Effect of combined procedural pain interventions during neonatal intensive care on sleep, cognitive development, and internalizing behavior: a follow-up analysis of a randomized controlled trial.
Repeated procedural pain can cause preterm infants to spend excessive time awake at the cost of sleep and can have a detrimental impact on later cognitive and behavioral development. What's more, poor sleep may be correlated with worse cognitive development and more internalizing behaviors in infants and toddlers. ⋯ Total sleep time and night awakenings at 3, 6, and 12 months old; the cognitive development (adaptability, gross motor, fine motor, language, and personal-social domains) at 12 and 24 months old measured by the Chinese version of Gesell Development Scale; and the internalizing behavior at 24 months old measured by the Chinese version of Child Behavior Checklist were assessed. Our findings showed the potential benefits of combined pain interventions during neonatal intensive care for preterm infant's later sleep, motor and language development, and internalizing behavior, and the effect of combined pain interventions on motor development and internalizing behavior might be moderated by the mean total sleep duration and night awakenings at 3, 6, and 12 months old.

Randomized Controlled Trial
Adding a nonpainful end to reduce pain recollection of Pap smear screening: a randomized controlled trial.
The pain experienced during Pap tests is a crucial gap in reducing cervical cancer burden. This study sought to investigate whether adding a nonpainful step at the end of Pap tests helps women recall less pain. We conducted a randomized controlled trial on women aged 30 to 70 years at a cervical cancer screening center. ⋯ Furthermore, the modified Pap test increased 1-year willingness grade to receive further Pap tests (adjusted β [SE], 2.11 [0.27]; P < 0.001). In conclusion, adding a nonpainful step at the end of Pap smear screening reduces on-site and long-term recalled pain and strengthens willingness to undergo subsequent Pap tests regularly. The modified Pap test contributes to cervical cancer screening participation.
