Meta-Analysis
A systematic review and random-effects model network meta-analysis was conducted to compare the efficacy, acceptability, tolerability, and safety of pharmacological interventions for adults with acute bipolar mania. We searched PubMed, the Cochrane Library, and Embase databases for eligible studies published before March 14, 2021. Randomized controlled trials (RCTs) of oral medication monotherapy lasting ≥10 days in adults with mania were included, and studies that allowed the use of antipsychotics as a rescue medication during a trial were excluded. The primary outcomes were response to treatment (efficacy) and all-cause discontinuation (acceptability). The secondary outcomes were the improvement of mania symptoms and discontinuation due to inefficacy. Of the 79 eligible RCTs, 72 double-blind RCTs of 23 drugs and a placebo were included in the meta-analysis (mean study duration = 3.96 ± 2.39 weeks, n = 16442, mean age = 39.55 years, with 50.93% males). Compared with the placebo, aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, tamoxifen, valproate, and ziprasidone outperformed response to treatment (N = 56, n = 14503); aripiprazole, olanzapine, quetiapine, and risperidone had lower all-cause discontinuation; however, topiramate had higher all-cause discontinuation (N = 70, n = 16324). Compared with the placebo, aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, tamoxifen, valproate, and ziprasidone outperformed the improvement of mania symptoms (N = 61, n = 15466), and aripiprazole, asenapine, carbamazepine, cariprazine, haloperidol, lithium, olanzapine, paliperidone, quetiapine, risperidone, valproate, and ziprasidone had lower discontinuation due to inefficacy (N = 50, n = 14284). In conclusions, these antipsychotics, carbamazepine, lithium, tamoxifen, and valproate were effective for acute mania. However, only aripiprazole, olanzapine, quetiapine, and risperidone had better acceptability than the placebo.

Meta-Analysis
BACKGROUND
Bipolar depression constitutes a major public health problem due to its substantial burden of disease. Although pharmacological interventions are available, guidelines required updated evidence synthesis to improve their current recommendations. In order to inform evidence-based prescribing, we investigated the comparative efficacy and tolerability of pharmacological interventions for acute bipolar depression.
METHODS
We conducted a systematic review and network meta-analysis. We searched for randomised controlled trials comparing pharmacological interventions with each other or placebo in adults with acute bipolar depression (type I, type II, or not otherwise specified), excluding those with substance misuse, unipolar depression, or schizophrenia, in MEDLINE, Embase, PsycINFO, Google Scholar, Cochrane Library, Web of Knowledge, CINAHL, and LILACS from database inception up to April 13, 2023. Criteria for eligibility were a duration of 2-16 weeks with masked outcome assessments, and we included combination, add-on design, and monotherapy studies. The co-primary outcomes were depressive symptoms, examined with standardised mean differences (SMDs), and manic switch, examined with odds ratios (ORs). We also investigated dropouts due to any reason, inefficacy, adverse events, and important side-effects as secondary outcomes. The confidence in the evidence was evaluated using Confidence-In-Network-Meta-Analysis (CINeMA). The study was registered with PROSPERO, CRD42020171726.
RESULTS
We analysed data from 101 randomised controlled trials covering 20 081 participants, 8063 men (41·7%) and 11 263 women (58·3%; sex not available in four studies), mean age 41·0 years (range of means 28·7-53·6 years), and 68 medications and placebo. Ethnicity data were not available. With moderate confidence in the evidence, olanzapine plus fluoxetine, quetiapine, olanzapine, lurasidone, lumateperone, cariprazine, and lamotrigine were more efficacious than placebo in reducing depressive symptoms, with SMDs ranging from 0·41 (95% CI 0·19-0·64) for olanzapine plus fluoxetine to 0·16 (0·03-0·29) for lamotrigine. Several other drugs might also be efficacious, but the confidence in the evidence was very low to low. Antidepressants as a class seem to be efficacious, but had a higher risk for manic switch compared to antipsychotics. Medications differed in their side-effect profiles.
INTERPRETATION
This is, to our knowledge, the largest network meta-analysis of pharmacotherapy for bipolar depression to date. Olanzapine plus fluoxetine, quetiapine, olanzapine, lurasidone, lumateperone, cariprazine, and lamotrigine were found to be more efficacious than placebo in adults with acute bipolar depression, with good confidence in the evidence, and to differ in their side-effect profiles. These findings can inform evidence-based care and the development of treatment guidelines internationally.

Review
BACKGROUND
Nausea and vomiting in pregnancy (NVP) affects up to 85% of all women during pregnancy, but for the majority self-management suffices. For the remainder, symptoms are more severe and the most severe form of NVP - hyperemesis gravidarum (HG) - affects 0.3-1.0% of pregnant women. There is no widely accepted point at which NVP becomes HG.
OBJECTIVES
This study aimed to determine the relative clinical effectiveness and cost-effectiveness of treatments for NVP and HG.
DATA SOURCES
MEDLINE, EMBASE, Cumulative Index to Nursing and Allied Health Literature, Cochrane Central Register of Controlled Trials, PsycINFO, Commonwealth Agricultural Bureaux (CAB) Abstracts, Latin American and Caribbean Health Sciences Literature, Allied and Complementary Medicine Database, British Nursing Index, Science Citation Index, Social Sciences Citation Index, Scopus, Conference Proceedings Index, NHS Economic Evaluation Database, Health Economic Evaluations Database, China National Knowledge Infrastructure, Cochrane Database of Systematic Reviews and Database of Abstracts of Reviews of Effects were searched from inception to September 2014. References from studies and literature reviews identified were also examined. was hand-searched, as were websites of relevant organisations. Costs came from NHS sources.
REVIEW METHODS
A systematic review of randomised and non-randomised controlled trials (RCTs) for effectiveness, and population-based case series for adverse events and fetal outcomes. Treatments: vitamins B6 and B12, ginger, acupressure/acupuncture, hypnotherapy, antiemetics, dopamine antagonists, 5-hydroxytryptamine receptor antagonists, intravenous (i.v.) fluids, corticosteroids, enteral and parenteral feeding or other novel treatment. Two reviewers extracted data and quality assessed studies. Results were narratively synthesised; planned meta-analysis was not possible due to heterogeneity and incomplete reporting. A simple economic evaluation considered the implied values of treatments.
RESULTS
Seventy-three studies (75 reports) met the inclusion criteria. For RCTs, 33 and 11 studies had a low and high risk of bias respectively. For the remainder ( = 20) it was unclear. The non-randomised studies ( = 9) were low quality. There were 33 separate comparators. The most common were acupressure versus placebo ( = 12); steroid versus usual treatment ( = 7); ginger versus placebo ( = 6); ginger versus vitamin B6 ( = 6); and vitamin B6 versus placebo ( = 4). There was evidence that ginger, antihistamines, metoclopramide (mild disease) and vitamin B6 (mild to severe disease) are better than placebo. Diclectin [Duchesnay Inc.; doxylamine succinate (10 mg) plus pyridoxine hydrochloride (10 mg) slow release tablet] is more effective than placebo and ondansetron is more effective at reducing nausea than pyridoxine plus doxylamine. Diclectin before symptoms of NVP begin for women at high risk of severe NVP recurrence reduces risk of moderate/severe NVP compared with taking Diclectin once symptoms begin. Promethazine is as, and ondansetron is more, effective than metoclopramide for severe NVP/HG. I.v. fluids help correct dehydration and improve symptoms. Dextrose saline may be more effective at reducing nausea than normal saline. Transdermal clonidine patches may be effective for severe HG. Enteral feeding is effective but extreme method treatment for very severe symptoms. Day case management for moderate/severe symptoms is feasible, acceptable and as effective as inpatient care. For all other interventions and comparisons, evidence is unclear. The economic analysis was limited by lack of effectiveness data, but comparison of costs between treatments highlights the implications of different choices.
LIMITATIONS
The main limitations were the quantity and quality of the data available.
CONCLUSION
There was evidence of some improvement in symptoms for some treatments, but these data may not be transferable across disease severities. Methodologically sound and larger trials of the main therapies considered within the UK NHS are needed.

Meta-Analysis Review
BACKGROUND
Several augmentation strategies have been used to improve symptomatology in patients not adequately responding to clozapine. Several randomised controlled trials (RCTs) have evaluated the efficacy of different strategies to augment clozapine. This systematic review and meta-analysis reviewed the available RCTs that have evaluated the clinical efficacy of various pharmacological agents, non-pharmacological strategies (occupational therapy, cognitive behaviour therapy), and somatic treatment [electroconvulsive therapy (ECT), repetitive transcranial magnetic stimulation, etc.)] as augmenting agents to clozapine.
METHODS
Data were extracted using standard procedures, and risk of bias was evaluated. Effect sizes were computed for the individual studies.
RESULTS
Forty-five clinical trials were evaluated. The pooled effect size for various antipsychotic medications was 0.103 (95% CI: 0.288-0.493, < 0.001); when the effect size was evaluated for specific antipsychotics for which more than one trial was available, the effect size for risperidone was -0.27 and that for aripiprazole was 0.57. The effect size for lamotrigine was 0.145, and that for topiramate was 0.392. The effect size for ECT was 0.743 (CI: 0.094-1.392). Risk of bias was low (mean Jadad score - 3.93). Largest effect sizes were seen for mirtazapine (effect size of 5.265). Most of the studies can be considered underpowered and limited by small sample sizes.
CONCLUSIONS
To conclude, based on the findings of the present systematic review and meta-analysis, it can be said that compared to other treatment strategies, clozapine non-responsive patients respond maximum to mirtazapine followed by ECT.

Meta-Analysis Review
Pharmacological treatment of major depressive disorder is often inefficient, and multiple strategies are used for inadequate response to antidepressants. Second-generation antipsychotics are used as augmentation measures in clinical practice; evidence of their efficacy and acceptability is insufficient, and it remains confusing as to which drug should be selected first. In this systematic review and network meta-analysis, we included randomised controlled trials of second-generation antipsychotics used as adjunctive treatment in patients with suboptimal responses. Outcome measures were efficacy (response and remission) and acceptability (dropout due to any reason and adverse events). Thirty-three trials comprising 10 602 participants were included. Regarding efficacy, response rates indicated that all antipsychotics except for ziprasidone were more efficacious than the placebo, with the odds ratios (ORs) ranging from 1.34 for olanzapine and cariprazine [95% credible interval (CrI) 1.04-1.73 and 1.07-1.67, respectively] to 2.17 for risperidone (95% CrI 1.38-3.42). When considering remission, cariprazine was not effective (OR 1.21, 95% CrI 0.96-1.54). For acceptability, quetiapine (OR 0.68, 95% CrI 0.50-0.91), brexpiprazole (OR 0.69, 95% CrI 0.55-0.86), and cariprazine (OR 0.61, 95% CrI 0.46-0.82) were worse than the placebo. With regards to tolerability, only olanzapine (OR 0.51, 95% CrI 0.25-1.07) and risperidone (OR 0.48, 95% CrI 0.10-2.21) showed no significant differences compared with placebo. The administration of adjunctive antipsychotics is associated with high effectiveness and low acceptability. Risperidone and aripiprazole are more efficacious and accepted than other atypical antipsychotics.

Meta-Analysis
BACKGROUND & AIMS
Although there have been multiple drugs tested in gastroparesis, their relative efficacy and safety are unknown. We evaluated this in a network meta-analysis of randomized controlled trials (RCTs).
METHODS
We searched the literature to September 7, 2022. We judged the efficacy of drugs based on global symptoms of gastroparesis; individual symptoms, including nausea, vomiting, abdominal pain, bloating, or fullness; and safety according to total adverse events and adverse events leading to withdrawal. We extracted data as intention-to-treat analyses, assuming dropouts to be treatment failures and reporting pooled relative risks (RRs) of not improving with 95% confidence intervals (CIs), ranking drugs according to P-score.
RESULTS
We identified 29 RCTs (3772 patients). Based on global symptoms, clebopride ranked first for efficacy (RR, 0.30; 95% CI, 0.16-0.57; P-score = .99) followed by domperidone (RR, 0.68; 95% CI, 0.48-0.98; P-score = .76). No other drug was superior to placebo. Only 2 drug classes were efficacious: in rank order, oral dopamine antagonists (RR, 0.58; 95% CI, 0.44-0.77; P-score = .96) and tachykinin-1 antagonists (RR, 0.69; 95% CI, 0.52-0.93; P-score = .83). For individual symptoms, oral metoclopramide ranked first for nausea (RR 0.46; 95% CI, 0.21-1.00; P-score = .95), fullness (RR 0.67; 95% CI, 0.35-1.28; P-score = .86), and bloating (RR 0.53; 95% CI, 0.30-0.93; P-score = .97), based on only 1 small trial. Only prucalopride was more likely to be associated with adverse events than placebo.
CONCLUSIONS
In a network meta-analysis, oral dopamine antagonists and tachykinin-1 antagonists were more efficacious than placebo for gastroparesis, but confidence in the evidence was low to moderate for most comparisons. There is an unmet need for efficacious therapies for gastroparesis.

Review
BPSD (Behavioral and Psychological Symptoms in Dementia) affects virtually all patients with dementia. The aim of this review is to present information on epidemiology, consequences and evidence-based non-pharmacological and pharmacological treatment approaches. The review also covers recent literature derived from a systematic literature Medline search on BPSD. Results indicate that BPSD are major risk factors for an earlier placement of affected individuals in nursing homes and a potentially more severe course of dementia over time. Treatment of BPSD is complex and includes both strategies.

BACKGROUND
Nausea and vomiting are a common clinical symptom in the advanced cancer patient. Pharmacologic management is important. Evidence for drug choices and guidelines are needed to help clinicians manage nausea and vomiting in this population METHODS: Evidence from a systematic review published in 2010, initial MASCC guidelines developed from a systematic review of literature to 2015, and a new systematic review of randomized trials published between 2015 and February 2, 2021, was combined to establish a new guideline.
RESULTS
A search of the literature between 2015 and February 2, 2021, revealed 257 abstracts of which there was one systematic review and 4 randomized trials which were used to modify the guideline. The new guideline is as follows: First Line: Metoclopramide (II) multiple small RCTs including a placebo-controlled trial, haloperidol (II) multiple non-placebo-controlled RCTs, high consensus. Second line: Methotrimeprazine (II) 1 well-powered non-placebo-controlled RCT, olanzapine (II) 1 placebo-controlled pilot RCT, high consensus. Third line: Tropisetron (II) large unblinded lower quality non-placebo-controlled RCT, levosulpiride (II) 1 blinded non-placebo-controlled pilot RCT, high consensus.
DISCUSSION
Haloperidol, metoclopramide, methotrimeprazine, olanzapine tropisetron, and levosulpiride have been antiemetics used in randomized trials with antiemetic activity demonstrated. There are only three placebo-controlled randomized trials we could find in our literature review. Placebo responses varied significantly between two randomized trials. More randomized placebo-controlled trials with either metoclopramide or haloperidol rescue are needed to clarify antiemetic choices in advanced cancer.
CONCLUSION
First-line antiemetics for nausea and vomiting in advanced cancer are metoclopramide and haloperidol, and second-line medications are methotrimeprazine and olanzapine.

Meta-Analysis
Antipsychotic drugs differ in their propensity to cause extrapyramidal side-effects (EPS), but their dose-effects are unclear. Therefore, we conducted a systematic review and dose-response meta-analysis. We searched multiple electronic databases up to 20.02.2023 for fixed-dose studies investigating 16 second-generation antipsychotics and haloperidol (all formulations and administration routes) in adults with acute exacerbations of schizophrenia. The primary outcome was the number of participants receiving antiparkinsonian medication, and if not available, the number of participants with extrapyramidal side-effects (EPS) and the mean scores of EPS rating scales were used as proxies. The effect-size was odds ratio (ORs) compared with placebo. One-stage random-effects dose-response meta-analyses with restricted cubic splines were conducted to estimate the dose-response curves. We also examined the relationship between dopamine D receptor (DR) occupancy and ORs by estimating occupancies from administrated doses. We included data from 110 studies with 382 dose arms (37193 participants). Most studies were short-term with median duration of 6 weeks (range 3-26 weeks). Almost all antipsychotics were associated with dose-dependent EPS with varied degrees and the maximum ORs ranged from OR = 1.57 95%CI [0.97, 2.56] for aripiprazole to OR = 7.56 95%CI [3.16, 18.08] for haloperidol at 30 mg/d. Exceptions were quetiapine and sertindole with negligible risks across all doses. There was very low quality of findings for cariprazine, iloperidone, and zotepine, and no data for clozapine. The DR occupancy curves showed that the risk increased substantially when DR occupancy exceeded 75-85%, except for DR partial agonists that had smaller ORs albeit high DR occupancies. In conclusion, we found that the risk of EPS increases with rising doses and differs substantially in magnitude among antipsychotics, yet exceptions were quetiapine and sertindole with negligible risks. Our data provided additional insights into the current DR therapeutic window for EPS.

Review
BACKGROUND
Chlorpromazine is the only drug approved by the US Food and Drug Administration for the treatment of hiccups; however, many other pharmacologic treatments have been proposed for intractable and persistent hiccups. Currently, there is little evidence to support the use of one agent over another.
OBJECTIVE
This review aims to identify literature concerning the use of pharmacologic treatments for intractable and persistent hiccups with the goal of evaluating therapies in terms of their level of evidence, mechanism of action, efficacy, dosing, onset of action, and adverse effects.
METHODS
A systematic literature search of PubMed, Embase, the Cochrane Library, and the New York Academy of Medicine was performed to find articles where a pharmacologic agent was used to treat intractable or persistent hiccups between the years 1966 and 2016. The GRADE method was used to assess the level of evidence for the studies included in this review.
RESULTS
This review identified 26 articles involving 10 pharmacologic treatment options that met our inclusion criteria. Amitriptyline, baclofen, gabapentin, haloperidol, metoclopramide, midazolam, nifedipine, nimodipine, orphenadrine, and valproic acid were found in the literature to be successful in treating hiccups.
CONCLUSION
Baclofen, gabapentin, and metoclopramide were the only agents that were studied in a prospective manner, while only baclofen and metoclopramide were studied in randomized controlled trials. No specific recommendations can be made for treating intractable and persistent hiccups with the evidence currently available in the literature. Therapy selection should be specific to individual patients, their underlying comorbidities, etiology of hiccups, and take into account the individual properties of the drugs.
