Randomized Controlled Trial
Exploration and Validation of the Behavioural Pain Measures and Physiological Pain Measures Factor Structure Extracted from the Pain Assessment Tool Item Scores for Infants Admitted to Neonatal Intensive Care.
The objective of the study was to explore and then validate the factor structure of the Pain Assessment Tool (PAT). ⋯ The PAT assesses both Behavioral Pain and Physiological Pain Measures, and these dimensions need to be considered separately when assessing pain in infants in the neonatal intensive care unit. Behavioral item scores may be insufficient for detecting pain in premature infants if used alone.

The objective of this study was to systematically locate, critically appraise, and summarize clinical measurement research addressing the use of Brief Pain Inventory-Short Form (BPI-SF) and Revised Short McGill Pain Questionnaire Version-2 (SF-MPQ-2) in pain-related musculoskeletal (MSK) conditions. ⋯ Evidence of high-to-moderate quality supports the internal consistency, criterion-convergent validity, structural validity, and responsiveness of the BPI-SF and SF-MPQ-2 and establishes their use as generic multidimensional pain outcomes in MSK populations. However, more studies of high quality are still needed on their retest reliability, known-group validity, cross-cultural validity, interpretability properties, and measurement error indices in different MSK populations.

Patients with herpes zoster (HZ) would benefit from accurate prediction of whether they are likely to develop postherpetic neuralgia (PHN). We investigated whether a circulating biomarker of neuronal damage could be a predictor of PHN in this nonmatched prospective, nested, case-control study. ⋯ Our results indicate that circulating MBP level in patients with HZ is a predictor for PHN. The combination of clinical predictors and MBP level enhanced the prediction performance.

The objective of this study was to compare children and adolescents with overlapping chronic pains (OCP) to those with single chronic pains (SCP) among youth presenting in specialized clinical settings, in an effort to identify potential risk factors for developing overlapping pains. ⋯ Given their tendency toward more psychological and medical comorbidities, patients with OCP may require more intense and diverse treatment approaches. Some early life experiences may be a risk factor for development of OCP. Longitudinal studies are needed to fully evaluate the heightened risk for OCP associated with some of these factors.
