Randomized Controlled Trial
Minimum Effective Concentration of Bupivacaine in Ultrasound-Guided Femoral Nerve Block after Arthroscopic Knee Meniscectomy: A Randomized, Double-Blind, Controlled Trial.
Adequate analgesia is important for early hospital discharge after meniscectomy. A femoral nerve block may reduce the need for systemic analgesics, with fewer side effects; however, motor block can occur. Ultrasound-guided femoral nerve block may reduce the required local anesthetic concentration, preventing motor block. ⋯ Bupivacaine EC50 for ultrasound-guided femoral nerve block was 0.160 (95% CI: 0.150 - 0.189), and EC90 was 0.271 (95% CI: 0.196 - 0.300).

Chronic neuropathic pain has been recognized as contributing to a significant proportion of chronic pain globally. Among these, spinal pain is of significance with failed back surgery syndrome (FBSS), generating considerable expense for the health care systems with increasing prevalence and health impact. ⋯ There is significant (Level I to II) evidence of the efficacy of spinal cord stimulation in lumbar FBSS; whereas, there is moderate (Level II to III) evidence for high frequency stimulation; there is limited evidence for adaptive stimulation and burst stimulation.

Basing their rationale on multiple publications from Institute of Medicine (IOM), specifically Crossing the Quality Chasm, policy makers have focused on a broad range of issues, including assessment of the influence of medical practice organization structures on quality performance and development of quality measures. The 2006 Tax Relief and Health Care Act established the Physician Quality Reporting System (PQRS), to enable eligible professionals to report health care quality and health outcome information that cannot be obtained from standard Medicare claims. However, the Patient Protection and Affordable Care Act (ACA) of 2010 required the Centers for Medicare and Medicaid Services (CMS) to incorporate a combination of cost and quality into the payment systems for health care as a precursor to value-based payments. ⋯ Indeed, all of the above may only be one-third or one-fourth of the cost to completely implement the PQRS system. Thus far, data across all specialties shows participation to be around 50%. In addition, penalties for lack of reporting of PQRS measures stands to be controversial to the Supreme Court ruling that unfunded mandates must not be permitted and also lack of significant relationships with improvement in quality in the overall analysis in multiple publications.

Multicenter Study Observational Study
A Novel Mini-invasive Approach to the Treatment of Neuropathic Pain: The PENS Study.
Peripheral neuromodulation is often used as chronic neuropathic pain treatment. Percutaneous electrical nerve stimulation (PENS) is generally utilized with several probes at the same time and repeated treatments. ⋯ PENS therapy produced significant and long-lasting pain relief in chronic peripheral neuropathic pains of different etiology. The present study confirms the feasibility, safety, and repeatability of this minimally invasive technique.

Review Meta Analysis Comparative Study
Pneumogastric (Vagus) Nerve Activity Indexed by Heart Rate Variability in Chronic Pain Patients Compared to Healthy Controls: A Systematic Review and Meta-Analysis.
A large body of scientific literature derived from experimental studies emphasizes the vital role of vagal-nociceptive networks in acute pain processing. However, research on vagal activity, indexed by vagally-mediated heart rate variability (vmHRV) in chronic pain patients (CPPs), has not yet been summarized. ⋯ The present meta-analysis is the most extensive review of the current evidence on vagal activity indexed by vmHRV in CPPs. CPPs were shown to have lower vagal activity, indexed by vmHRV, compared to HCs. Several covariates in this relationship have been identified. Further research is needed to investigate vagal activity in CPPs, in particular prospective and longitudinal follow-up studies are encouraged.
