Meta-Analysis Review
Drug addiction is a serious disease with damaging effects on the brain and physical health. Despite the increase in the number of affected individuals, there are few effective pharmacological treatment options for substance use disorders. The study of the influence of an individual's genetic features on the treatment response may help to identify more efficacious treatment options. This systematic review focuses on the serotonergic system because of its relevant role in mood and impulse control disorders, and its contribution to the development and maintenance of drug use disorders. In particular, we examine the role of serotonergic genes in the response to pharmacotherapy for alcohol, cocaine and nicotine addiction. Current evidence suggests that genetic variability of the serotonergic biosynthesis enzyme tryptophan hydroxylase 2 (TPH2) and the serotonin transporter (SLC6A4) genes mediates the efficacy of several addiction treatments, such as ondansetron and disulfiram, and the antidepressants bupropion, nortriptyline and sertraline.

Meta-Analysis Review
BACKGROUND
Nausea and vomiting remain a problem for children undergoing treatment for malignancies despite new antiemetic therapies. Optimising antiemetic regimens could improve quality of life by reducing nausea, vomiting, and associated clinical problems. This is an update of the original systematic review.
OBJECTIVES
To assess the effectiveness and adverse events of pharmacological interventions in controlling anticipatory, acute, and delayed nausea and vomiting in children and young people (aged less than 18 years) about to receive or receiving chemotherapy.
SEARCH METHODS
Searches included the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS, PsycINFO, conference proceedings of the American Society of Clinical Oncology, International Society of Paediatric Oncology, Multinational Association of Supportive Care in Cancer, and ISI Science and Technology Proceedings Index from incept to December 16, 2014, and trial registries from their earliest records to December 2014. We examined references of systematic reviews and contacted trialists for information on further studies. We also screened the reference lists of included studies.
SELECTION CRITERIA
Two review authors independently screened abstracts in order to identify randomised controlled trials (RCTs) that compared a pharmacological antiemetic, cannabinoid, or benzodiazepine with placebo or any alternative active intervention in children and young people (less than 18 years) with a diagnosis of cancer who were to receive chemotherapy.
DATA COLLECTION AND ANALYSIS
Two review authors independently extracted outcome and quality data from each RCT. When appropriate, we undertook meta-analysis.
MAIN RESULTS
We included 34 studies that examined a range of different antiemetics, used different doses and comparators, and reported a variety of outcomes. The quality and quantity of included studies limited the exploration of heterogeneity to narrative approaches only.The majority of quantitative data related to the complete control of acute vomiting (27 studies). Adverse events were reported in 29 studies and nausea outcomes in 16 studies.Two studies assessed the addition of dexamethasone to 5-HT3 antagonists for complete control of vomiting (pooled risk ratio (RR) 2.03; 95% confidence interval (CI) 1.35 to 3.04). Three studies compared granisetron 20 mcg/kg with 40 mcg/kg for complete control of vomiting (pooled RR 0.93; 95% CI 0.80 to 1.07). Three studies compared granisetron with ondansetron for complete control of acute nausea (pooled RR 1.05; 95% CI 0.94 to 1.17; 2 studies), acute vomiting (pooled RR 2.26; 95% CI 2.04 to 2.51; 3 studies), delayed nausea (pooled RR 1.13; 95% CI 0.93 to 1.38; 2 studies), and delayed vomiting (pooled RR 1.13; 95% CI 0.98 to 1.29; 2 studies). No other pooled analyses were possible.Narrative synthesis suggests that 5-HT3 antagonists are more effective than older antiemetic agents, even when these agents are combined with a steroid. Cannabinoids are probably effective but produce frequent side effects.
AUTHORS' CONCLUSIONS
Our overall knowledge of the most effective antiemetics to prevent chemotherapy-induced nausea and vomiting in childhood is incomplete. Future research should be undertaken in consultation with children, young people, and families that have experienced chemotherapy and should make use of validated, age-appropriate measures. This review suggests that 5-HT3 antagonists are effective in patients who are to receive emetogenic chemotherapy, with granisetron or palonosetron possibly better than ondansetron. Adding dexamethasone improves control of vomiting, although the risk-benefit profile of adjunctive steroid remains uncertain.

Review
BACKGROUND/AIMS
An updated systematic review and meta-analysis was conducted to assess the effect of prophylactic dexamethasone for tracheal intubation of general anesthesia on postoperative sore throat (POST).
METHODS
Comprehensive literature search of databases for randomized controlled trials (RCTs), including Embase, PubMed, and Cochrane Library, which evaluate the effect of prophylactic dexamethasone on POST was conducted. RevMan 5.0 and STATA 12.0 software were used to perform meta-analyses.
RESULTS
Fourteen RCTs totaling 1,837 patients were included for analysis. Compared with placebo, a significant reduction in the incidence of POST (OR 0.44, 95% CI 0.33-0.58, <0.00001), hoarseness (OR 0.42, 95% CI 0.31-0.58, <0.00001), and postoperative nausea and vomiting (PONV) (OR 0.06, 95% CI 0.03-0.14, <0.00001) and a comparable incidence of cough (OR 0.59, 95% CI 0.19-1.89, =0.38) was described in patients receiving dexamethasone, with or without concomitant drugs. Dexamethasone ≥0.2 mg/kg had a statistically greater impact on reducing the incidence of POST than dexamethasone 0.1-0.2 mg/kg, while dexamethasone ≤0.1 mg/kg did not. Dexamethasone was as effective as other drugs such as ondansetron, magnesium sulfate, ketamine gargle, betamethasone gel, and ketorolac for reducing POST (OR 0.70, 95% CI 0.46-1.07, =0.10). Dexamethasone plus a different drug was more effective than dexamethasone alone for reducing the incidence of POST at 24 hours (OR 0.40, 95% CI 0.21-0.77, =0.006). Compared with controls, a statistically higher blood glucose level was the only adverse event during the immediate postoperative period in patients receiving dexamethasone.
CONCLUSIONS
Intravenous dexamethasone ≥0.2 mg/kg within 30 minutes before or after induction of general anesthesia should be recommended as grade 1A evidence with safety and efficacy in reducing the incidence of POST, hoarseness, and PONV in patients without pregnancy, diabetes mellitus, or contraindications for corticosteroids.

This investigation examined the efficacy of ondansetron (intervention) versus metoclopramide (control) in managing parturient females with hyperemesis gravidarum (HG), by pooling data from randomized controlled trials (RCTs) using a meta-analysis approach. From inception until January 2022, five information sources were screened: Cochrane Central Register of Controlled Trials, Google Scholar, Scopus, PubMed and Web of Science. Quality assessment was done through the Cochrane Risk of Bias (version 2) assessment tool. The mean difference (MD) with 95% confidence interval (CI) was used to summarize the continuous data in a fixed- or random-effects model, depending on the extent of between-study heterogeneity. Five RCTs were included, comprising a total of 695 patients (355 and 340 females were assigned to ondansetron and metoclopramide, respectively). Four RCTs had an overall "low" risk of bias, whereas one RCT had an overall "some concerns" due to lack of sufficient information about randomization. There was no significant difference between both groups regarding the pregnancy-unique quantification of emesis and nausea score [MD=0.23, 95% CI (-0.42, 0.88), p=0.49], length of hospital stay [MD=-0.17 days, 95% CI (-0.35, 0.02), p=0.08], the number of doses of drug received [MD=0.45, 95% CI (-0.08, 0.98), p=0.10], and duration of intravenous fluids [MD=-1.73 hours, 95% CI (-5.79, 2.33), p=0.40]. Among parturient females with HG, there was no substantial difference in efficacy between both agents. Nevertheless, ondansetron is favored over metoclopramide in view of its trending therapeutic efficacy and better safety profile.

Meta-Analysis Review
BACKGROUND
Serotonin (5-HT3) receptor antagonists are commonly used to decrease nausea and vomiting for surgery patients, but these agents may be harmful. We conducted a systematic review on the comparative safety of 5-HT3 receptor antagonists.
METHODS
Searches were done in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify studies comparing 5-HT3 receptor antagonists with each other, placebo, and/or other antiemetic agents for patients undergoing surgical procedures. Screening search results, data abstraction, and risk of bias assessment were conducted by two reviewers independently. Random-effects pairwise meta-analysis and network meta-analysis (NMA) were conducted. PROSPERO registry number: CRD42013003564.
RESULTS
Overall, 120 studies and 27,787 patients were included after screening of 7,608 citations and 1,014 full-text articles. Significantly more patients receiving granisetron plus dexamethasone experienced an arrhythmia relative to placebo (odds ratio (OR) 2.96, 95 % confidence interval (CI) 1.11-7.94), ondansetron (OR 3.23, 95 % CI 1.17-8.95), dolasetron (OR 4.37, 95 % CI 1.51-12.62), tropisetron (OR 3.27, 95 % CI 1.02-10.43), and ondansetron plus dexamethasone (OR 5.75, 95 % CI 1.71-19.34) in a NMA including 31 randomized clinical trials (RCTs) and 6,623 patients of all ages. No statistically significant differences in delirium frequency were observed across all treatment comparisons in a NMA including 18 RCTs and 3,652 patients.
CONCLUSION
Granisetron plus dexamethasone increases the risk of arrhythmia.

Meta-Analysis Review
BACKGROUND
Nausea and vomiting is a common and distressing presenting complaint in emergency departments (ED). The aetiology of nausea and vomiting in EDs is diverse and drugs are commonly prescribed. There is currently no consensus as to the optimum drug treatment of nausea and vomiting in the adult ED setting.
OBJECTIVES
To provide evidence of the efficacy and safety of antiemetic medications in the management of nausea and vomiting in the adult ED setting.
SEARCH METHODS
We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2014, Issue 8), MEDLINE (OvidSP) (January 1966 to August 2014), EMBASE (OvidSP) (January 1980 to August 2014) and ISI Web of Science (January 1955 to August 2014). We also searched relevant clinical trial registries and conference proceedings.
SELECTION CRITERIA
We included randomized controlled trials (RCTs) of any drug in the treatment of nausea and vomiting in the treatment of adults in the ED. Study eligibility was not restricted by language or publication status.
DATA COLLECTION AND ANALYSIS
Two review authors independently performed study selection, data extraction and assessment of risk of bias in included studies. We contacted authors of studies to obtain missing information if required.
MAIN RESULTS
We included eight trials, involving 952 participants, of which 64% were women. Included trials were generally of adequate quality, with six trials at low risk of bias, and two trials at high risk of bias. Three trials with 518 participants compared five different drugs with placebo; all reported the primary outcome as mean change in visual analogue scale (VAS) (0 to 100) for nausea severity from baseline to 30 minutes. Trials did not routinely report other primary outcomes of the change in nausea VAS at 60 minutes or number of vomiting episodes. Differences in mean VAS change from baseline to 30 minutes between placebo and the drugs evaluated were: metoclopramide (three trials, 301 participants; mean difference (MD) -5.27, 95% confidence interval (CI) -11.33 to 0.80), ondansetron (two trials, 250 participants; MD -4.32, 95% CI -11.20 to 2.56), prochlorperazine (one trial, 50 participants; MD -1.80, 95% CI -14.40 to 10.80), promethazine (one trial, 82 participants; MD -8.47, 95% CI -19.79 to 2.85) and droperidol (one trial, 48 participants; MD -15.8, 95% CI -26.98 to -4.62). The only statistically significant change in baseline VAS to 30 minutes was for droperidol, in a single trial of 48 participants. No other drug was statistically significantly superior to placebo. Other included trials evaluated a drug compared to "active controls" (alternative antiemetic). There was no convincing evidence of superiority of any particular drug compared to active control. All trials included in this review reported adverse events, but they were variably reported precluding meaningful pooling of results. Adverse events were generally mild, there were no reported serious adverse events. Overall, the quality of the evidence was low, mainly because there were not enough data.
AUTHORS' CONCLUSIONS
In an ED population, there is no definite evidence to support the superiority of any one drug over any other drug, or the superiority of any drug over placebo. Participants receiving placebo often reported clinically significant improvement in nausea, implying general supportive treatment such as intravenous fluids may be sufficient for the majority of people. If a drug is considered necessary, choice of drug may be dictated by other considerations such as a person's preference, adverse-effect profile and cost. The review was limited by the paucity of clinical trials in this setting. Future research should include the use of placebo and consider focusing on specific diagnostic groups and controlling for factors such as intravenous fluid administered.

Meta-Analysis Review
AIM
We assessed the efficacy and safety of 5-hydroxytryptamine (5-HT3) receptor antagonists in adults with non-constipated irritable bowel syndrome (IBS) or diarrhea-predominant IBS (IBS-D).
METHODS
We searched PubMed, MEDLINE, EMBASE, and the Cochrane Controlled Trials Register for randomized controlled trials (RCTs) involving adults with non-constipated IBS or IBS-D that compared 5-HT3 receptor antagonists with placebo or other conventional treatment. Dichotomous symptom data were pooled to obtain the relative risk (RR) and 95% confidence intervals (CIs) for improving global IBS symptoms, abdominal pain and abnormal bowel habits, or stool consistency symptoms after therapy, and adverse events, including constipation. Meta- analysis was performed with Mantel Haenszel method using Revman 5.3 software.
RESULTS
We included 21 RCTs; 16 were high quality (Jadad score ≥ 4). The pooled RR of global IBS symptoms improved by 5-HT3 receptor antagonists versus placebo or mebeverine was 1.56 (95% CI: 1.43-1.71); alosetron, ramosetron, and cilansetron had similar treatment effects. The pooled RR of abdominal pain relieved by 5-HT3 receptor antagonists versus placebo was 1.33 (95% CI: 1.26-1.39). The pooled RR showed that 5-HT3 receptor antagonists improved abnormal bowel habits or stool consistency symptoms (RR = 1.63, 95% CI: 1.33, 1.99). The pooled RR of adverse events following 5-HT3 receptor antagonist treatment was 1.15 (95% CI: 1.08, 1.22). Subgroup analysis indicated that alosetron had a high rate of adverse effects (RR = 1.16, 95% CI: 1.08, 1.25); adverse events following ramosetron treatment were not statistically significantly different. 5-HT3 receptor antagonists were likelier to cause constipation: the pooled RR of constipation developing with 5-HT3 receptor antagonist versus placebo was 3.71 (95% CI: 2.98-4.61). However, constipation was likelier in patients with non-constipated IBS after taking 5-HT3 receptor antagonists than in patients with IBS-D only (non-constipated IBS and IBS-D: RR = 5.28 [95% CI: 3.93, 7.08] vs. IBS-D only 3.24 [2.54, 4.12]).
CONCLUSIONS
Ramosetron, cilansetron, ondansetron, and alosetron are effective for treating non-constipated IBS and IBS-D. Our systematic review found rare serious adverse events.

Dexamethasone combined with other antiemetics versus single antiemetics for prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy: An updated systematic review and meta-analysis.
OBJECTIVE
A systematic review and meta-analysis of published randomized controlled trials was performed to update the present evidence about the safety and efficacy of dexamethasone combined with other antiemetics versus single antiemetics for the prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy.
METHODS
A computer literature search of PubMed, Scopus, Web of Science and Embase was conducted to identify the relevant randomized controlled trials. In addition, a manual search of reference lists of the retrieved articles was conducted. Relevant outcomes were pooled as odds ratio (OR) by RevMan version 5.3 for windows.
RESULTS
Pooled data from 14 RCTs (1542 patients) favored dexamethasone combined with other antiemetics over single antiemetics as a prophylaxis against postoperative nausea and vomiting after laparoscopic cholecystectomy in the early postoperative period (OR = 0.39, 95% CI [0.27 to 0.54], p < 0.00001), late postoperative period (OR = 0.36, 95% CI [0.23 to 0.56], p < 0.00001), and overall postoperative period (OR = 0.34, 95% CI [0.23 to 0.51], p < 0.00001). Subsequently, rescue antiemetic usage was significantly lower in the combination group (OR = 0.25, 95% CI [0.16 to 0.41], p < 0.00001). Subgroup analysis showed that all combinations of dexamethasone and other antiemetics were superior to corresponding singel antiemetics except for the combination of dexamethasone and ramosetron which was not superior to ramosetron alone in all postoperative periods and the combination of dexamethasone and granisetron which was not superior to granisetron alone in the early postoperative period (OR = 0.26, 95% CI [0.07 to 1.01], p = 0.05). For all adverse events, there was no significant difference between the two groups.
CONCLUSION
Dexamethasone combined with other antiemetics provided better prophylaxis than single antiemetics against postoperative nausea and vomiting after laparoscopic cholecystectomy. The underlying mechanism of dexamethasone action and its optimal dose should be further investigated.

Meta-Analysis Review
BACKGROUND
Harmful alcohol use is defined as unhealthy alcohol use that results in adverse physical, psychological, social, or societal consequences and is among the leading risk factors for disease, disability and premature mortality globally. The burden of harmful alcohol use is increasing in low- and middle-income countries (LMICs) and there remains a large unmet need for indicated prevention and treatment interventions to reduce harmful alcohol use in these settings. Evidence regarding which interventions are effective and feasible for addressing harmful and other patterns of unhealthy alcohol use in LMICs is limited, which contributes to this gap in services.
OBJECTIVES
To assess the efficacy and safety of psychosocial and pharmacologic treatment and indicated prevention interventions compared with control conditions (wait list, placebo, no treatment, standard care, or active control condition) aimed at reducing harmful alcohol use in LMICs.
SEARCH METHODS
We searched for randomized controlled trials (RCTs) indexed in the Cochrane Drugs and Alcohol Group (CDAG) Specialized Register, the Cochrane Clinical Register of Controlled Trials (CENTRAL) in the Cochrane Library, PubMed, Embase, PsycINFO, CINAHL, and the Latin American and Caribbean Health Sciences Literature (LILACS) through 12 December 2021. We searched clinicaltrials.gov, the World Health Organization International Clinical Trials Registry Platform, Web of Science, and Opengrey database to identify unpublished or ongoing studies. We searched the reference lists of included studies and relevant review articles for eligible studies.
SELECTION CRITERIA
All RCTs comparing an indicated prevention or treatment intervention (pharmacologic or psychosocial) versus a control condition for people with harmful alcohol use in LMICs were included.
DATA COLLECTION AND ANALYSIS
We used standard methodological procedures expected by Cochrane.
MAIN RESULTS
We included 66 RCTs with 17,626 participants. Sixty-two of these trials contributed to the meta-analysis. Sixty-three studies were conducted in middle-income countries (MICs), and the remaining three studies were conducted in low-income countries (LICs). Twenty-five trials exclusively enrolled participants with alcohol use disorder. The remaining 51 trials enrolled participants with harmful alcohol use, some of which included both cases of alcohol use disorder and people reporting hazardous alcohol use patterns that did not meet criteria for disorder. Fifty-two RCTs assessed the efficacy of psychosocial interventions; 27 were brief interventions primarily based on motivational interviewing and were compared to brief advice, information, or assessment only. We are uncertain whether a reduction in harmful alcohol use is attributable to brief interventions given the high levels of heterogeneity among included studies (Studies reporting continuous outcomes: Tau² = 0.15, Q =139.64, df =16, P<.001, I² = 89%, 3913 participants, 17 trials, very low certainty; Studies reporting dichotomous outcomes: Tau²=0.18, Q=58.26, df=3, P<.001, I² =95%, 1349 participants, 4 trials, very low certainty). The other types of psychosocial interventions included a range of therapeutic approaches such as behavioral risk reduction, cognitive-behavioral therapy, contingency management, rational emotive therapy, and relapse prevention. These interventions were most commonly compared to usual care involving varying combinations of psychoeducation, counseling, and pharmacotherapy. We are uncertain whether a reduction in harmful alcohol use is attributable to psychosocial treatments due to high levels of heterogeneity among included studies (Heterogeneity: Tau² = 1.15; Q = 444.32, df = 11, P<.001; I²=98%, 2106 participants, 12 trials, very low certainty). Eight trials compared combined pharmacologic and psychosocial interventions with placebo, psychosocial intervention alone, or another pharmacologic treatment. The active pharmacologic study conditions included disulfiram, naltrexone, ondansetron, or topiramate. The psychosocial components of these interventions included counseling, encouragement to attend Alcoholics Anonymous, motivational interviewing, brief cognitive-behavioral therapy, or other psychotherapy (not specified). Analysis of studies comparing a combined pharmacologic and psychosocial intervention to psychosocial intervention alone found that the combined approach may be associated with a greater reduction in harmful alcohol use (standardized mean difference (standardized mean difference (SMD))=-0.43, 95% confidence interval (CI): -0.61 to -0.24; 475 participants; 4 trials; low certainty). Four trials compared pharmacologic intervention alone with placebo and three with another pharmacotherapy. Drugs assessed were: acamprosate, amitriptyline, baclofen disulfiram, gabapentin, mirtazapine, and naltrexone. None of these trials evaluated the primary clinical outcome of interest, harmful alcohol use. Thirty-one trials reported rates of retention in the intervention. Meta-analyses revealed that rates of retention between study conditions did not differ in any of the comparisons (pharmacologic risk ratio (RR) = 1.13, 95% CI: 0.89 to 1.44, 247 participants, 3 trials, low certainty; pharmacologic in addition to psychosocial intervention: RR = 1.15, 95% CI: 0.95 to 1.40, 363 participants, 3 trials, moderate certainty). Due to high levels of heterogeneity, we did not calculate pooled estimates comparing retention in brief (Heterogeneity: Tau² = 0.00; Q = 172.59, df = 11, P<.001; I = 94%; 5380 participants; 12 trials, very low certainty) or other psychosocial interventions (Heterogeneity: Tau² = 0.01; Q = 34.07, df = 8, P<.001; I = 77%; 1664 participants; 9 trials, very low certainty). Two pharmacologic trials and three combined pharmacologic and psychosocial trials reported on side effects. These studies found more side effects attributable to amitriptyline relative to mirtazapine, naltrexone and topiramate relative to placebo, yet no differences in side effects between placebo and either acamprosate or ondansetron. Across all intervention types there was substantial risk of bias. Primary threats to validity included lack of blinding and differential/high rates of attrition.
AUTHORS' CONCLUSIONS
In LMICs there is low-certainty evidence supporting the efficacy of combined psychosocial and pharmacologic interventions on reducing harmful alcohol use relative to psychosocial interventions alone. There is insufficient evidence to determine the efficacy of pharmacologic or psychosocial interventions on reducing harmful alcohol use largely due to the substantial heterogeneity in outcomes, comparisons, and interventions that precluded pooling of these data in meta-analyses. The majority of studies are brief interventions, primarily among men, and using measures that have not been validated in the target population. Confidence in these results is reduced by the risk of bias and significant heterogeneity among studies as well as the heterogeneity of results on different outcome measures within studies. More evidence on the efficacy of pharmacologic interventions, specific types of psychosocial interventions are needed to increase the certainty of these results.

Meta-Analysis Review
BACKGROUND
Serotonin (5-HT3) receptor antagonists are commonly used to decrease nausea and vomiting for surgery patients. We conducted a systematic review on the comparative efficacy of 5-HT3 receptor antagonists.
METHODS
Searches were done in MEDLINE, Embase, and the Cochrane Central Register of Controlled Trials to identify studies comparing 5-HT3 receptor antagonists with each other, placebo, and/or combined with other antiemetic agents for patients undergoing surgical procedures. Screening search results, data abstraction, and risk of bias assessment were conducted by two reviewers independently. Random-effects pairwise meta-analysis and network meta-analysis (NMA) were conducted. PROSPERO registry number: CRD42013003564.
RESULTS
Overall, 450 studies and 80,410 patients were included after the screening of 7,608 citations and 1,014 full-text articles. Significantly fewer patients experienced nausea with any drug relative to placebo, except for ondansetron plus metoclopramide in a NMA including 195 RCTs and 24,230 patients. Significantly fewer patients experienced vomiting with any drug relative to placebo except for palonosetron plus dexamethasone in NMA including 238 RCTs and 12,781 patients. All agents resulted in significantly fewer patients with postoperative nausea and vomiting versus placebo in a NMA including 125 RCTs and 16,667 patients.
CONCLUSIONS
Granisetron plus dexamethasone was often the most effective antiemetic, with the number needed to treat ranging from two to nine.
