Meta-Analysis Review
OBJECTIVE
The goal of this systematic review and metaanalysis is to compare pregnancy outcomes between pregnant women undergoing treatment for opioid use disorder with buprenorphine-naloxone and those undergoing treatment for opioid use disorder with other forms of medication-assisted treatment.
STUDY DESIGN
PubMed, Embase, PsycINFO, Cochrane Clinical Trials, and Web of Science were searched to identify studies assessing the relationship between maternal buprenorphine-naloxone use and pregnancy outcomes. Outcomes assessed included neonatal abstinence syndrome diagnosis and treatment, neonatal intensive care unit admission, length of neonatal hospital stay, delivery complications, mode of delivery, labor analgesia, illicit drug use, medication-assisted treatment dosage, gestational age at delivery, breastfeeding status, miscarriage, congenital anomalies, intrauterine fetal demise, birthweight, head circumference, length, and Apgar scores.
RESULTS
Overall, 5 studies comprising 6 study groups met the inclusion criteria. Of the 1875 mother-baby dyads available for analysis, medications prescribed as part of the medication-assisted treatment included buprenorphine-naloxone, buprenorphine alone, methadone, or long-acting opioids. There were no serious adverse maternal or neonatal outcomes associated with maternal buprenorphine-naloxone use reported among any of the studies. Women prescribed with buprenorphine-naloxone for delivered neonates who were less likely to require treatment for neonatal abstinence syndrome were compared with pregnant women prescribed with other opioid agonist medications. Of the remaining outcomes assessed, metaanalysis did not detect any statistically significant differences when comparing the groups of women using buprenorphine-naloxone with the groups of women prescribed with other medications as part of the medication-assisted treatment.
CONCLUSION
Pregnant women undergoing treatment for opioid use disorder with buprenorphine-naloxone do not experience significantly different pregnancy outcomes than women undergoing treatment with other forms of opioid agonist medication-assisted therapy.

Review
BACKGROUND
Sinomenine (SIN) is the main pharmacologically active component of Sinomenii Caulis and protects against rheumatoid arthritis (RA). In recent years, many studies have been conducted to elucidate the pharmacological mechanisms of SIN in the treatment of RA. However, the molecular mechanism of SIN in RA has not been fully elucidated.
PURPOSE
To summarize the pharmacological effects and molecular mechanisms of SIN in RA and clarify the most valuable regulatory mechanisms of SIN to provide clues and a basis for basic research and clinical applications.
METHODS
We systematically searched SciFinder, Web of Science, PubMed, China National Knowledge Internet (CNKI), the Wanfang Databases, and the Chinese Scientific Journal Database (VIP). We organized our work based on the PRISMA statement and selected studies for review based on predefined selection criteria.
OUTCOME
After screening, we identified 201 relevant studies, including 88 clinical trials and 113 in vivo and in vitro studies on molecular mechanisms. Among these studies, we selected key results for reporting and analysis.
CONCLUSIONS
We found that most of the known pharmacological mechanisms of SIN are indirect effects on certain signaling pathways or proteins. SIN was manifested to reduce the release of inflammatory cytokines such as Tumor necrosis factor-α (TNF-α), Interleukin-6 (IL-6), and IL-1β, thereby reducing the inflammatory response, and apparently blocking the destruction of bone and cartilage. The regulatory effects on inflammation and bone destruction make SIN a promising drug to treat RA. More notably, we believe that the modulation of α7nAChR and the regulation of methylation levels at specific GCG sites in the mPGES-1 promoter by SIN, and its mechanism of directly targeting GBP5, certainly enriches the possibilities and the underlying rationale for SIN in the treatment of inflammatory immune-related diseases.

Review
Retention in medication-assisted treatment among opiate-dependent patients is associated with better outcomes. This systematic review (55 articles, 2010-2014) found wide variability in retention rates (i.e., 19%-94% at 3-month, 46%-92% at 4-month, 3%-88% at 6-month, and 37%-91% at 12-month follow-ups in randomized controlled trials), and identified medication and behavioral therapy factors associated with retention. As expected, patients who received naltrexone or buprenorphine had better retention rates than patients who received a placebo or no medication. Consistent with prior research, methadone was associated with better retention than buprenorphine/naloxone. And, heroin-assisted treatment was associated with better retention than methadone among treatment-refractory patients. Only a single study examined retention in medication-assisted treatment for longer than 1 year, and studies of behavioral therapies may have lacked statistical power; thus, studies with longer-term follow-ups and larger samples are needed. Contingency management showed promise to increase retention, but other behavioral therapies to increase retention, such as supervision of medication consumption, or additional counseling, education, or support, failed to find differences between intervention and control conditions. Promising behavioral therapies to increase retention have yet to be identified.

Review
BACKGROUND
Heroin craving is a trigger for relapse and dropping out of treatment. Methadone has been the standard medication for the management of heroin craving.
OBJECTIVES
We explored the medication options other than methadone which may have heroin anticraving properties.
METHODS
To be selected for the review, articles had to include outcome measures of the effect of the studied medication on subjective and/or objective opiate craving and be of the following two types: (1) randomized, controlled, and/or double-blind clinical trials (RCTs) examining the relationship between the studied medication and heroin craving; (2) nonrandomized and observational studies (NRSs) examining the relationship between the studied medication and heroin craving. Thirty-three articles were initially included in the review. Twenty-one were excluded because they did not meet the inclusion criteria. We present the results of 12 articles that met all the inclusion criteria.
RESULTS
Some new medications have been under investigation and seem promising for the treatment of opiate craving. Buprenorphine is the second most studied medication after methadone for its effect on opiate craving. At doses above 8 mg daily, it seems very promising and practical for managing opiate craving in patients receiving long-term opioid maintenance treatment.
CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE
In doses higher than 8 mg daily, buprenorphine is an appropriate treatment for opiate craving. More research with rigorous methodology is needed to study the effect of buprenorphine on heroin craving. Also more studies are needed to directly compare buprenorphine and methadone with regard to their effects on heroin craving.

With the current opiate epidemic in the United States, there is renewed interest in evaluating non-opiate adjuvant medications as effective alternatives for the prevention and treatment of postoperative pain. A systematic review of randomized, controlled trials on Pub Med, Medline, and Embase was conducted looking on postoperative pain management from 2008 to 2018. Studies were included if they used a gabapentenoid with or without acetaminophen and evaluated supplemental opiate use. All adult (18 years or older) surgical populations were considered for inclusion, and fourteen clinical trials met inclusion criteria. Gabapentenoid dosing varied among studies. In nine of fourteen studies, there was a finding of superiority as compared to placebo in managing postoperative pain and decreasing supplemental opiate use. Pregabalin was used in twelve of the fourteen studies and gabapentin was used in two of the fourteen studies. Of the nine studies that found a benefit from using a gabapentoid, all included pregabalin. While the rate of adverse effects was low in all studies, it was found to increase as dosages increased. Results support that pregabalin has a role in decreasing postoperative pain intensity and supplemental opiate use; however, the optimal dose or dosing regimen is not yet well understood.

Meta-Analysis Review
BACKGROUND
Neuraxial opioids provide effective analgesia for Caesarean delivery, however, pruritus can be a troubling side-effect. Effective agents to prevent pruritus are needed. Our objective was to perform an updated systematic review and network meta-analysis to provide clinicians with a comparison of relative efficacy of available interventions to reduce the incidence of pruritus, induced by either intrathecal or epidural single-shot morphine, in women undergoing Caesarean delivery.
METHODS
Databases systematically searched (up to January 2022) included PubMed MEDLINE, Web of Science, EBSCO CINAHL, Embase, LILACS, and two Cochrane databases. We included randomised, controlled trials involving adult female patients undergoing Caesarean delivery. We pooled trials comparing interventions used for preventing pruritus after Caesarean delivery and performed a Bayesian model network meta-analysis.
RESULTS
The final primary network included data from comparisons of 14 distinct interventions (including placebo) used to reduce the incidence of pruritus in 6185 participants. We judged five interventions to be 'definitely superior' to placebo: propofol, opioid agonist-antagonists (neuraxial), opioid antagonists, opioid agonist-antagonists (systemic), and serotonin antagonists. For the network evaluating the incidence of severe pruritus (warranting additional therapeutic treatment of pruritus), data were available for 14 interventions (including placebo) in 4489 patients. For this outcome, we judged three interventions to be 'definitely superior' to placebo: dopamine antagonists (neuraxial) and systemic and neuraxial opioid agonist-antagonists.
CONCLUSION
Our analysis found several interventions to be effective in reducing the incidence of pruritus. Although sub-hypnotic doses of propofol appear to have an antipruritic effect, replication of this finding and further investigation of optimal dosing are warranted.

Review
BACKGROUND
Opioid drugs, including buprenorphine, are commonly used to treat neuropathic pain, and are considered effective by some professionals. Most reviews have examined all opioids together. This review sought evidence specifically for buprenorphine, at any dose, and by any route of administration. Other opioids are considered in separate reviews.
OBJECTIVES
To assess the analgesic efficacy of buprenorphine for chronic neuropathic pain in adults, and the adverse events associated with its use in clinical trials.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and EMBASE from inception to 11 June 2015, together with reference lists of retrieved papers and reviews, and two online study registries.
SELECTION CRITERIA
We included randomised, double-blind studies of two weeks' duration or longer, comparing any oral dose or formulation of buprenorphine with placebo or another active treatment in chronic neuropathic pain.
DATA COLLECTION AND ANALYSIS
Two review authors independently searched for studies, extracted efficacy and adverse event data, and examined issues of study quality. We did not carry out any pooled analyses.
MAIN RESULTS
Searches identified 10 published studies, and one study with results in ClinicalTrials.gov. None of these 11 studies satisfied our inclusion criteria, and so we included no studies in the review.
AUTHORS' CONCLUSIONS
There was insufficient evidence to support or refute the suggestion that buprenorphine has any efficacy in any neuropathic pain condition.

Review
OBJECTIVES
To assess the clinical effectiveness and cost-effectiveness of buprenorphine maintenance therapy (BMT) and methadone maintenance therapy (MMT) for the management of opioid-dependent individuals.
DATA SOURCES
Major electronic databases were searched from inception to August 2005. Industry submissions to the National Institute for Health and Clinical Excellence were accessed.
REVIEW METHODS
The assessment of clinical effectiveness was based on a review of existing reviews plus an updated search for randomised controlled trials (RCTs). A decision tree with Monte Carlo simulation model was developed to assess the cost-effectiveness of BMT and MMT. Retention in treatment and opiate abuse parameters were sourced from the meta-analysis of RCTs directly comparing flexible MMT with flexible dose BMT. Utilities were derived from a panel representing a societal perspective.
RESULTS
Most of the included systematic reviews and RCTs were of moderate to good quality, and focused on short-term (up to 1-year follow-up) outcomes of retention in treatment and the level of opiate use (self-report or urinalysis). Most studies employed a trial design that compared a fixed-dose strategy (i.e. all individuals received a standard dose) of MMT or BMT and were conducted in predominantly young men who fulfilled criteria as opiate-dependent or heroin-dependent users, without significant co-morbidities. RCT meta-analyses have shown that a fixed dose of MMT or BMT has superior levels of retention in treatment and opiate use than placebo or no treatment, with higher fixed doses being more effective than lower fixed doses. There was evidence, primarily from non-randomised observational studies, that fixed-dose MMT reduces mortality, HIV risk behaviour and levels of crime compared with no therapy and one small RCT has shown the level of mortality with fixed-dose BMT to be significantly less than with placebo. Flexible dosing (i.e. individualised doses) of MMT and BMT is more reflective of real-world practice. Retention in treatment was superior for flexible MMT than flexible BMT dosing but there was no significant difference in opiate use. Indirect comparison of data from population cross-sectional studies suggests that mortality with BMT may be lower than that with MMT. A pooled RCT analysis showed no significant difference in serious adverse events with MMT compared with BMT. Although treatment modifier evidence was limited, adjunct psychosocial and contingency interventions (e.g. financial incentives for opiate-free urine samples) appeared to enhance the effects of both MMT and BMT. Also, MMT and BMT appear to be similarly effective whether delivered in a primary care or outpatient clinic setting. Although most of the included economic evaluations were considered to be of high quality, none used all of the appropriate parameters, effectiveness data, perspective and comparators required to make their results generalisable to the NHS context. One company (Schering-Plough) submitted cost-effectiveness evidence based on an economic model that had a 1-year time horizon and sourced data from a single RCT of flexible-dose MMT compared with flexible-dose BMT and utility values obtained from the literature; the results showed that for MMT vs no drug therapy, the incremental cost-effectiveness ratio (ICER) was pound 12,584/quality-adjusted life-year (QALY), for BMT versus no drug therapy, the ICER was pound 30,048/QALY and in a direct comparison, MMT was found to be slightly more effective and less costly than BMT. The assessment group model found for MMT versus no drug therapy that the ICER was pound 13,697/QALY, for BMT versus no drug therapy that the ICER was pound 26,429/QALY and, as with the industry model, in direct comparison, MMT was slightly more effective and less costly than BMT. When considering social costs, both MMT and BMT gave more health gain and were less costly than no drug treatment. These findings were robust to deterministic and probabilistic sensitivity analyses.
CONCLUSIONS
Both flexible-dose MMT and BMT are more clinically effective and more cost-effective than no drug therapy in dependent opiate users. In direct comparison, a flexible dosing strategy with MMT was found be somewhat more effective in maintaining individuals in treatment than flexible-dose BMT and therefore associated with a slightly higher health gain and lower costs. However, this needs to be balanced by the more recent experience of clinicians in the use of buprenorphine, the possible risk of higher mortality of MMT and individual opiate-dependent users' preferences. Future research should be directed towards the safety and effectiveness of MMT and BMT; potential safety concerns regarding methadone and buprenorphine, specifically mortality and key drug interactions; efficacy of substitution medications (in particular patient subgroups, such as within the criminal justice system, or within young people); and uncertainties in cost-effectiveness identified by current economic models.

Meta-Analysis Review
OBJECTIVES
This meta-analysis sought to evaluate the efficacy of opioid antagonists in promoting long-term smoking cessation. Post-treatment abstinence was examined as a secondary outcome and effects on withdrawal symptoms, craving and reduced consumption were also explored.
DESIGN
The search strategy for this meta-analysis included clinical trials (published and unpublished data) in the Cochrane Tobacco Addiction Group Specialized Register and MEDLINE.
PARTICIPANTS
Adult smokers.
INTERVENTIONS
We included randomised trials comparing opioid antagonists to placebo or an alternative therapy for smoking cessation and reported data on abstinence for a minimum of 6 months.
PRIMARY AND SECONDARY OUTCOME MEASURES
Outcomes included smoking abstinence at long-term follow-up (primary); abstinence at end of treatment (secondary); and effects on withdrawal, craving and smoking consumption (exploratory).
RESULTS
8 trials with a total of 1213 participants were included. Half the trials examined the benefit of adding naltrexone versus placebo to nicotine replacement therapy (NRT). There was no significant difference between naltrexone and placebo alone (relative risk (RR) 1.00; 95% CI 0.66 to 1.51) or as an adjunct to NRT (RR 0.95; 95% CI 0.70 to 1.30), with an overall pooled estimate of RR 0.97; 95% CI 0.76 to 1.24. Findings for naltrexone effects on withdrawal, craving and reduced smoking were equivocal.
CONCLUSIONS
The findings indicate no beneficial effect of naltrexone alone or as an adjunct to NRT on short-term or long-term smoking abstinence. While further trials may narrow the confidence limits, they are unlikely to appreciably alter the conclusion.

Meta-Analysis Review
BACKGROUND
This is an updated version of a Cochrane review first published in Issue 3, 2006 (Perry 2006). The review represents one in a family of four reviews focusing on the effectiveness of interventions in reducing drug use and criminal activity for offenders. This specific review considers interventions for female drug-using offenders.
OBJECTIVES
To assess the effectiveness of interventions for female drug-using offenders in reducing criminal activity, or drug use, or both.
SEARCH METHODS
We searched 14 electronic bibliographic databases up to May 2014 and five additional Website resources (between 2004 and November 2011). We contacted experts in the field for further information.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) designed to reduce, eliminate or prevent relapse of drug use or criminal activity in female drug-using offenders. We also reported data on the cost and cost-effectiveness of interventions.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by The Cochrane Collaboration.
MAIN RESULTS
Nine trials with 1792 participants met the inclusion criteria. Trial quality and risks of bias varied across each study. We rated the majority of studies as being at 'unclear' risk of bias due to a lack of descriptive information. We divided the studies into different categories for the purpose of meta-analyses: for any psychosocial treatments in comparison to treatment as usual we found low quality evidence that there were no significant differences in arrest rates, (two studies; 489 participants; risk ratio (RR) 0.82, 95% confidence interval (CI) 0.45 to 1.52) or drug use (one study; 77 participants; RR 0.65, 95% CI 0.20 to 2.12), but we found moderate quality evidence that there was a significant reduction in reincarceration, (three studies; 630 participants; RR 0.46, 95% CI 0.34 to 0.64). Pharmacological intervention using buprenorphine in comparison to a placebo did not significantly reduce self reported drug use (one study; 36 participants; RR 0.58, 95% CI 0.25 to 1.35). No cost or cost-effectiveness evidence was reported in the studies.
AUTHORS' CONCLUSIONS
Three of the nine trials show a positive trend towards the use of any psychosocial treatment in comparison to treatment as usual showing an overall significant reduction in subsequent reincarceration, but not arrest rates or drug use. Pharmacological interventions in comparison to a placebo did not significantly reduce drug use and did not measure criminal activity. Four different treatment comparisons showed varying results and were not combined due to differences in the intervention and comparison groups. The studies overall showed a high degree of heterogeneity for types of comparisons and outcome measures assessed, which limited the possibility to pool the data. Descriptions of treatment modalities are required to identify the important elements for treatment success in drug-using female offenders. More trials are required to increase the precision of confidence with which we can draw conclusions about the effectiveness of treatments for female drug-using offenders.
