61 points; 95% CI, -4.30 to -1.09 (P = 0.24). For the comparison of topical ginger versus standard treatment, standard mean difference for pain was 0.79 mm; 95% CI, -1.97 to 0.39 (P = 0.19), and standard mean difference for knee function was -0.51 points; 95% CI, -1.15 to 0.13 (P = 0.12). LIMITATIONS The current evidence is heterogeneous and has a poor methodologic quality. CONCLUSIONS There is insufficient evidence to support the use of oral ginger compared with placebo in the pain relief and function improvement in patients with knee osteoarthritis. For other comparisons, no statistically significant differences were found.

OBJECTIVES The present meta-analysis aimed to evaluate the clinical efficacy of ketamine versus control in cesarean section anesthesia for reducing the postoperative pain and analgesia. STUDY DESIGN We used meta-analysis to address this concern. SETTING Meta-analysis-based study. METHODS The databases PubMed, Embase, and the Cochrane Library were systematically searched to identify the relevant randomized controlled trials (RCTs) of ketamine versus control in controlling pain after cesarean section from inception to August 2018. Based on the Cochrane Handbook, the combined analysis was performed using Revman 5.3 software. RESULTS A total of 20 RCTs with 1,737 patients who underwent cesarean section were included. Meta-analysis showed that the pain score in the ketamine group was less than that of the control group (mean difference [MD], -1.10; 95% confidence interval [CI], -1.61, -0.59; P less then 0.0001). Application of ketamine during cesarean section also resulted in decreased consumption of morphine when compared with the control group (MD, -6.11 mg; 95% CI, -9.93, -2.29; P = 0.002). In addition, the first time required for analgesia was significantly longer in the ketamine group than that of the control group (MD, 72.48 minutes; 95% CI, 50.85, 94.11; P less then 0.00001). LIMITATIONS Limited patients were included with moderate strength. CONCLUSIONS Ketamine supplementation during cesarean section reduces pain and morphine consumption and prolongs the postoperative analgesia. KEY WORDS Ketamine, cesarean section, randomized controlled trials, meta-analysis.BACKGROUND Pain medicine practices vary across different regions within a country and between countries. OBJECTIVES The objective of the survey was to study the variation in interventional pain medicine practices in the United Kingdom (UK) and the United States (US). METHODS A survey was designed in 2019 on Survey Monkey®. Pain physicians from the UK and the US were invited to respond. RESULTS A total of 120 responses were received from pain physicians in the UK and 122 from the US. Twenty-six percent and 90% of pain physicians in the UK and US, respectively, are in full-time pain medicine practice. There was marked variation in the utilization of diagnostic medial branch blocks before performing radiofrequency denervation (RFD) between the UK and the US. In the UK, 42% of pain physicians, and 50% in the US, use a 20-gauge or a 22-gauge radiofrequency needle for lumbar RFD. Around 30% to 50% of pain physicians, both in the UK and the US, discontinued antithrombotic agents before medial branch blocks at all thde variation in interventional pain medicine practices both in the UK and the US. The relevant governing bodies in the UK and in the US should encourage clinicians to use at least an 18-gauge radiofrequency needle for RFD at the lumbar level. Discontinuing antithrombotic agents for the lumbar medial branch block is not justifiable. Pain physicians must discuss the advantages and disadvantages of using a nonparticulate over a particulate steroid preparation with the patient before performing TFESI as a standard procedure during the consenting process. KEY WORDS Antithrombotic agents, epidural steroid, medial branch blocks, pain practice variations, particulate and nonparticulate steroids, radiofrequency denervation, spinal interventions.BACKGROUND Interventional techniques for managing spinal pain, from conservative modalities to surgical interventions, are thought to have been growing rapidly. Interventional techniques take center stage in managing chronic spinal pain. Specifically, facet joint interventions experienced explosive growth rates from 2000 to 2009, with a reversal of these growth patterns and in some settings, a trend of decline after 2009. OBJECTIVES The objectives of this assessment of utilization patterns include providing an update of facet joint interventions in managing chronic spinal pain in the fee-for-service (FFS) Medicare population of the United States from 2000 to 2018. STUDY DESIGN The study was designed to assess utilization patterns and variables of facet joint interventions in managing chronic spinal pain from 2000 to 2018 in the FFS Medicare population in the United States. METHODS Data for the analysis were obtained from the master database from the Centers for Medicare & Medicaid Services (CMS) physician/supf 112%. The proportion of cervical facet joint injection sessions to neurolysis sessions changed from 8.9 in 2000 to 2.4 in 2018. LIMITATIONS This analysis is limited by inclusion of only the FFS Medicare population, without adding utilization patterns of Medicare Advantage plans, which constitutes almost 30% of the Medicare population. The utilization data for individual states also continues to be sparse and may not be accurate. CONCLUSIONS Utilization patterns of facet joint interventions increased 1.9% per 100,000 Medicare population from 2009 to 2018. This results from an annual decline of - 0.2% lumbar facet joint injection sessions but with an increase of facet joint radiofrequency sessions of 7.4%.

Musculoskeletal disorders with low back and neck pain account for the third highest amount of various disease categories. Minimally invasive interventional techniques for managing spinal pain, including epidural injections, have been considered to be growing rapidly. However, recent analyses of utilization of interventional techniques from 2000 to 2018 has shown a decline of 2.6% and a decline of 21% from 2009 to 2018 for epidural and adhesiolysis procedures. OBJECTIVES The objectives of this analysis of epidural procedures from 2000 to 2018 are to provide an update on utilization of epidural injections in managing chronic pain in the fee-for-service (FFS) Medicare population, with a comparative analysis of 2000 to 2009 and 2009 to 2018. STUDY DESIGN Utilization patterns and variables of epidural injections in managing chronic spinal pain from 2000 to 2009 and from 2009 to 2018 in the FFS Medical and thoracic transforaminal injections with 35.1%, followed by lumbar interlaminar and caudal epidural injections of 34.9%, followed by 9.4% for lumbar/sacral transforaminal epidurals, and 3.5% for cervical and thoracic interlaminar epidurals. LIMITATIONS This analysis was limited by noninclusion of Medicare Advantage plans, which constitutes almost 30% of the Medicare population. In addition, utilization data for individual states continues to be sparse and may not be accurate or representative of the population. BAY2402234 CONCLUSIONS The declining utilization of epidural injections in all categories with an annual of 2.5% and overall decrease of 20.7% from 2009 to 2018 compared with annual increases of 7.3% and overall increase of 89.2% from 2000 to 2009 shows a slow decline of utilization of all epidural injections.

The use of cellular tissue raises a number of issues regarding the US Food and Drug Administration's (FDA) regulation in classifying these treatments as a drug versus just autologous tissue transplantation. In the case of BMC in musculoskeletal and spine care, this determination will likely hinge on whether BMC is homologous to the musculoskeletal system and spine. OBJECTIVES The aim of this review is to describe the current regulatory guidelines set in place by the FDA, specifically the terminology around "minimal manipulation" and "homologous use" within Regulation 21 CFR Part 1271, and specifically how this applies to the use of BMC in interventional musculoskeletal medicine. METHODS The methodology utilized here is similar to the methodology utilized in preparaticuloskeletal disorders meets the criteria of minimal manipulation and homologous use.

COVID-19 is a serious illness leading to multiple deaths in various countries including the United States. Several million Americans satisfy the Center for Disease Control and Prevention (CDC) criteria for being high risk. Unfortunately, the available supply of medical beds and equipment for mechanical ventilation are much less than is projected to be needed. The World Health Organization (WHO) and multiple agencies led by the CDC in the United States have attempted to organize intensive outbreak investigation programs utilizing appropriate preventive measures, evaluation, and treatment. The clinical spectrum of COVID-19 varies from asymptomatic forms to conditions encompassing multiorgan and systemic manifestations in terms of septic shock, and multiple organ dysfunction (MOD) syndromes. The presently approvcally ill COVID-19 patients will have access regardless of their financial circumstance.2. Institute appropriate safeguards to avoid negative consequences from unscrupulous actors.3. With proper informed consent from patients or proxy when necessary, and subject to accumulation of data in that cohort, allow the procedure to be initiated in critically ill patients who are not responding to conventional therapies.KEY WORDS Coronavirus, COVID-19, cytokine storm, multiorgan failure, expanded umbilical cord mesenchymal stem cells.Isolated hepatocytes can be obtained from the liver by collagenase infusion, a procedure that could affect cell isolation as well as the integrity of membrane receptors. In this respect we compared metabotropic glutamate subtype 5 receptor (mGluR5) protein expression and activity in rat hepatocytes isolated by two collagenases, type I and type IV. Hepatocytes were isolated from male Wistar rats (200-250 g) using collagenase I or collagenase IV and after isolation, viability and morphology of rat hepatocytes were assessed measuring mGluR5 protein expression by Western blot analyses. mGluR5 activation was evaluated by inositol-1-phosphate (IP-1) accumulation after treatment with the mGluR5 orthosteric agonist ACPD or the selective antagonist MPEP. No difference in cellular viability and morphology was observed using collagenase I when compared with collagenase IV. An increase in mGluR5 protein expression was observed in hepatocytes isolated using collagenase IV with respect to collagenase I. Moreover, hepatocytes treated with ACPD and with MPEP presented higher levels of IP-1 when isolated using collagenase IV compared to collagenase I.
