Review Meta Analysis
Effects of Different Therapeutic Exercise Modalities on Migraine or Tension-Type Headache: A Systematic Review and Meta-Analysis with a Replicability Analysis.
The primary aim of this study was to review the effect of exercise in comparison with a non-active treatment on pain intensity, frequency of headache episodes, headache duration, quality of life, medication use, and psychological symptoms, in patients with migraine or tension-type headache (TTH). A systematic search was conducted in various electronic databases to identify all relevant studies: Medline (PubMed), PEDro, EBSCO and Google Scholar. Clinical trials assessing the effects of exercise interventions in patients with primary headaches were selected. ⋯ Exercise could be considered as clinically relevant for the management of patients with primary headaches, but the presence of low certainty of evidence and low transparency and replicability limited its clinical application. PERSPECTIVE: This article presents current evidence about exercise interventions in patients with primary headaches, including migraine and tension-type headache. Existing findings are reviewed, and relevant data are provided on the effectiveness of each exercise modality, as well as its certainty of evidence and clinical applicability.

As opioid prescribing has declined, it is unclear how the landscape of prescription pain treatment across the U. S. has changed. We used nationally-representative data from the Medical Expenditure Health Survey, 2014 to 2018 to examine trends in prescriptions for opioid and non-opioid pain medications, including acetaminophen, non-steroidal anti-inflammatory drugs, gabapentinoids, and antidepressants among U. ⋯ Secondary analyses stratifiying within the 2014 to 2016 and 2016 to 2018 periods revealed particular increases in prescriptions for gabapentinoids (aOR = 1.13, 95% CI = 1.05-1.21) and antidepressants (aOR = 1.23, 95% CI = 1.12-1.35) since 2016. PERSPECTIVE: These data demonstrate that physicians are increasingly turning to CDC-recommended non-opioid medications for pain management, particularly antidepressants and gabapentinoids. However, evidence for these medications' efficacy in treating numerous common pain conditions, including low back pain, remains limited.

Conditioned Pain Modulation in Children: The Effects of Painful and Nonpainful Conditioning Stimuli.
Conditioned pain modulation (CPM), a psychophysical measure in which 1 pain stimulus (conditioning stimulus) is used to inhibit another pain stimulus (test stimulus), is an important indicator of endogenous pain inhibition in adults, but is understudied in children. Preliminary evidence suggests that CPM effects are present in healthy children and are more robust in adolescents. However, developmental differences in younger children are not well documented and few studies control for potential distraction effects of the conditioning stimulus (CS). ⋯ PERSPECTIVE: This study was successful in producing inhibitory CPM effects in physically healthy children while controlling for sensory distraction. The findings provide strong evidence that the obtained CPM responses cannot be attributed to sensory distraction or other nonspecific effects. Future studies could utilize CPM paradigms to study various aspects of pediatric endogenous pain inhibition, in order to better predict pain responses and improve interventions.

Review Meta Analysis
Pharmacist Involvement in Cancer Pain Management: A Systematic Review and Meta-Analysis.
This review aimed to critically evaluate the impact of pharmacist involvement in managing pain in cancer patients. Databases (including MEDLINE, Embase and CENTRAL) were searched with a broad search strategy for studies involving pharmacists and cancer pain management until February 10, 2021. The quality of studies and evidence were assessed using standardized tools and GRADE, respectively. ⋯ This indicates the involvement of pharmacists directly or in collaboration with healthcare professionals in the oncology team is highly beneficial for the patients. PERSPECTIVES: This systematic review presents a comprehensive evaluation of pharmacist involvement in cancer pain management. This shows the importance of direct involvement of the pharmacist or as an important member of the multidisciplinary oncology team.

Interhemispheric inhibition between primary sensory cortices is not influenced by acute muscle pain.
Bilateral deficits in sensorimotor function have been observed in unilateral musculoskeletal pain conditions. Altered interhemispheric inhibition (IHI) between primary sensory cortices (S1s) is one mechanism that could explain this phenomenon. However, IHI between S1s in response to acute muscle pain, and the relationship between IHI and pressure pain sensitivity in the unaffected limb have not been examined. ⋯ These findings suggest IHI between S1s is unaffected by acute, short-lasting muscle pain, despite the development of increased sensitivity to pressure in the unaffected APB muscle. PERSPECTIVE: IHI from the affected S1 (contralateral to the side of pain) to unaffected S1 is unaltered following the resolution of acute muscle pain. This finding suggests that IHI between S1s may not be relevant in the development of bilateral sensorimotor symptoms in unilateral pain conditions.
