Review Meta Analysis
Polyunsaturated Fatty Acids and Chronic Pain: A Systematic Review and Meta-analysis.
Chronic pain is one of the most frequent disease symptoms and represents a global health problem with a considerable economic burden. The role of polyunsaturated fatty acids (PUFA) in chronic pain conditions was debated during the last decade with conflicting results. ⋯ Our results suggest that Ω-3 PUFA supplementation moderately improves chronic pain, mainly that due to dysmenorrhea. Further investigation on the preventive potential of PUFA supplementation is needed, as the amount of evidence is scarce. Key words: Meta-analysis, systematic review, chronic pain, PUFA, supplementation, Ω-3, dysmenorrhea.

Review Meta Analysis
Can Unilateral Kyphoplasty Replace Bilateral Kyphoplasty in Treatment of Osteoporotic Vertebral Compression Fractures? A Systematic Review and Meta-analysis.
Kyphoplasty has been proven to be an efficient method to relieve patient suffering from osteoporotic vertebral compression fractures (OVCFs). Because of its technological superiority, unilateral kyphoplasty consumes less operative time and bone cement than traditional bilateral kyphoplasty. However, there is controversy about which method is most efficient in the treatment of OVCFs. Thus, an overall analysis should be performed to shed light on the facts corroborating both procedures. ⋯ Both unilateral kyphoplasty and bilateral kyphoplasty are safe and effective treatments for OVCFs. However, when operative time, cement volume, cement leakage, short-term general health, radiation dose, and hospitalization costs are taken into consideration, unilateral kyphoplasty may be the better choice. Yet, more high-quality RCTs with long-term follow-up are still required to make the final conclusion.Key words: Kyphoplasty, unilateral approach, bilateral approach, osteoporotic vertebral compression fractures, meta-analysis.
