Meta Analysis
Percutaneous Interventional Strategies for Migraine Prevention: A Systematic Review and Practice Guideline.
To systematically evaluate the efficacy and effectiveness of percutaneous interventional treatments for prevention of migraine through a qualitative and (when possible) quantitative analysis. ⋯ As informed by evidence related to the preselected outcomes, adverse event profile, cost, and values and preferences of patients, onabotulinumtoxinA received a strong recommendation for its use for chronic migraine prevention and a weak recommendation against its use for episodic migraine prevention. Greater occipital nerve blocks received a weak recommendation for their use for chronic migraine prevention. For greater occipital nerve block, steroid received a weak recommendation against its use vs the use of local anesthetic alone. Occipital nerve with supraorbital nerve blocks, sphenopalatine ganglion blocks, cervical spine percutaneous interventions, and implantable stimulation all received weak recommendations for their use for chronic migraine prevention. The committee found insufficient evidence to assess trigger point injections in migraine prevention and highly discouraged the use of intrathecal medication.

We conducted a systematic review and meta-analysis to examine the impact of perioperative intravenous lidocaine infusion on pain management scores, opioid consumption, adverse events, and hospital length of stay in patients undergoing spinal surgery. ⋯ Perioperative intravenous lidocaine infusion consistently improves analgesic measures in adult and pediatric populations in the first 24 hours, with an effective decrease in opioid consumption noted to 48 hours. These results are most generalizable in the adult population in the first 4-6 to 24 postoperative hours.

Meta Analysis
Implicit motor imagery of the foot and hand in people with Achilles tendinopathy: a left right judgement study.
To determine if impairment in motor imagery processes is present in Achilles tendinopathy (AT), as demonstrated by a reduced ability to quickly and accurately identify the laterality (left-right judgement) of a pictured limb. Additionally, this study aimed to use a novel data pooling approach to combine data collected at 3 different sites via meta-analytical techniques that allow exploration of heterogeneity. ⋯ Impairments in motor imagery performance for hands were not found in this study, and we found inconsistent results for foot accuracy. This contrasts to studies in persistent pain of limbs, face and knee osteoarthritis, and suggests that differences in pathoetiology or patient demographics may uniquely influence proprioceptive representation.

This systematic review and meta-analysis examined relationships between low back pain (LBP)-related disability and pain beliefs, including pain catastrophizing, pain-related fear, self-efficacy, and back pain beliefs, in non-English-speaking populations. Additionally, the effects of selected cultural factors (i.e., language/geographic area) on the strength of relationships were examined. ⋯ LBP-related disability was associated with pain-related beliefs, with consistency demonstrated for each pain belief construct across divergent non-English-speaking populations. Further research examining cultural factors, such as ethnicity or religion, and with a more diverse population is warranted.

Meta Analysis
Efficacy and Safety of N-acetylcysteine for the Management of Chronic Pain in Adults: A Systematic Review & Meta-analysis.
To assess the efficacy and safety of N-acetylcysteine in the treatment of chronic pain. ⋯ While there is some evidence to indicate N-acetylcysteine may provide analgesic efficacy for certain pain conditions, there is insufficient evidence to provide definitive evidence on NAC in chronic pain management. Larger-size RCTs spanning a variety of chronic pain conditions are needed to determine N-acetylcysteine's role, if any, in pain medicine.
