Sleep disturbance is prevalent among patients with chronic low back pain (CLBP). This systematic review aimed to summarize the evidence regarding the: (1) temporal relations between changes in sleep quality/quantity and the corresponding changes in pain and/or disability; and (2) role of baseline sleep quality/quantity in predicting future pain and/or disability in patients with CLBP. ⋯ This is the first systematic review to accentuate that improved self-reported sleep quality/quantity may be associated with improved pain/disability, although it remains unclear whether baseline sleep quality/quantity is a prognostic factor for CLBP. These findings highlight the importance of understanding the mechanisms underlying the relation between sleep and CLBP, which may inform the necessity of assessing or treating sleep disturbance in people with CLBP.

Abdominal pain is a common presenting complaint in youth seeking medical care and can be debilitating. Therefore, it is important to understand the impact of pain on functioning using a clinically sensitive approach. The National Institutes of Health has established a common core of psychometrically precise measures through the Patient-Reported Outcomes Measurement Information System (PROMIS) initiative. The Pediatric PROMIS-Pain Interference (PPPI) scale was developed to measure pain-related interference, drawing from existing legacy measures. However, its clinical validity has not been thoroughly established in clinical populations. The current study sought to develop clinical cut-points and investigate the validity of the PPPI in a large sample (N=5281) of youth presenting to gastroenterological care with abdominal pain symptoms. ⋯ Results suggest the PPPI is a valid measure with clinically meaningful cut-points to assess pain-related interference in youth with abdominal pain.

Intrathecal morphine (ITM) is frequently associated with side effects such as postoperative nausea and vomiting (PONV) and pruritus. The aim of this meta-analysis was to compare the impact of transversus abdominis plane (TAP) block versus ITM on side effects following cesarean delivery. ⋯ Compared with ITM, TAP block is associated with less PONV but inferior early analgesia after cesarean delivery. However, the heterogeneity among the studies highlights the need for more well-designed studies to obtain more robust conclusions.

Infants born preterm are exposed to repeated painful procedures during neonatal intensive care unit admission. Particularly in preterm infants, trajectories of pain response are not well understood. The aim of this study was to classify pain response trajectories over 2 minute following medically indicated heel lances in preterm infants. ⋯ In this sample of preterm infants receiving pain relief, most pain trajectories reflected mild to low-moderate pain that was stable over 2 minute after heel lance initiation. Trajectories were not consistent over multiple procedures within infants, and an overall mean pain score for the sample may misrepresent subgroups of pain response.

Along with the symptoms of pain and fatigue, pain catastrophizing and avoidance behaviors are highly prevalent and associated with functional impairment in fibromyalgia (FM) patients. Although pain and fatigue affect patients' quality of life, research has been exclusively focused on how pain affects physical activity and exercise. The aim of this study was to analyze the role of pain catastrophizing and preference for fatigue-avoidance goals in walking behavior and functional impairment in women with FM. ⋯ The present study may help clarify the connection between the factors that stop individuals with FM from implementing beneficial behaviors such as walking, and thus, allowing for the design of psychological interventions that seek to maintain physical functioning despite experiencing fatigue.
