Meta-Analysis
OBJECTIVE
This overview of systematic reviews (SRs) and meta-analyses aims to critically appraise the methodology and reporting quality of relevant SRs and meta-analyses with the aim of identifying whether or not the use of valproate can prevent the switch to mania associated with antidepressant treatment in Chinese patients with depressive episodes.
METHODS
Electronic databases China National Knowledge Infrastructure (CNKI), Chinese Scientific Journal Database (VIP database) and Wanfang Database were searched for related SRs and meta-analyses from inception to the search date within Chinese restrictions. A total of 2 reviewers independently selected SRs and meta-analyses and collected related data, and a third reviewer was introduced if any disagreement occurred during the assessment. The Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) and the US Agency for Healthcare Research and Quality (AHRQ) were employed to evaluate quality of the reporting and methodology.
RESULTS
The switch rate in the sodium valproate group by 99% and was significantly lower than in the antidepressant-only group (0% vs 5.7%; OR = 0.18; 95% CI, 0.04-0.84; Z = 2.18; P = .03). The magnesium valproate group was similar to the sodium valproate group in switch rate; the switch rate in the antidepressant group was (2.2% vs 16.92%; OR = 0.11; 95% CI, 0.03-0.39; Z = 3.47; P = .0005). The switch rate in the salt valproate combined with a selective serotonin reuptake inhibitor (SSRI) group was lower than in the SSRI group (0.51% vs 8.4%; OR = 0.15; 95% CI, 0.04-0.51; Z = 3.01; P = .003). The switch rate in the valproate combined with serotonin noradrenaline reuptake inhibitor (SNRI) group was similar to the valproate combined with SNRI group (2.3% vs 17.5%; OR = 0.12; 95% CI, 0.03-0.53; Z = 2.79; P = .05).
CONCLUSION
Salt valproate can reduce the switch rate related to antidepressant treatment in patients with depression.

Review
Serotonin syndrome (SS) is a drug‑induced, potentially fatal, clinical syndrome resulting from drugs that have serotonergic properties. Several antiepileptic drugs (AEDs) are known to have serotonergic properties and it can be hypothesized that such AEDs can cause SS. This study aims to review the literature on SS in patients receiving AEDs. We performed a systematic review of Scopus and MEDLINE/PUBMED for case reports and case series of SS where patients had received at least one AED at the onset of symptoms. The cases published in the English literature between 1 January 1991 and 1 April 2021 were included. Initial search identified 1263 articles of which 63 (76 patients) were included in the final analysis. Most of the included cases (53 cases, 70%) have been published in the last 10 years. The mean age of the 76 patients was 40.6 ± 17.8 years, and 51% of cases were females. These patients had been exposed to a total of 8 different types of AEDs. Valproic acid was the most common drug (29, 38%), followed by lamotrigine (22, 29%), gabapentin (16, 21%), pregabalin (seven, 9%), topiramate (five, 7%) and carbamazepine (two, 3%). There has been one case each with phenytoin and oxcarbazepine. Seven (9%) patients received more than one AEDs. Most patients (67, 88%) also received other serotoninergic agents. Only nine (12%) patients were on AEDs alone. The most common clinical condition for using AEDs was psychiatric disorders (36 patients, 47.3%), followed by migraine (17, 22.4%), other painful conditions (15, 19.7%), epilepsy (7, 9.2%), and perioperative conditions (8, 10.5%). Death was reported in two patients. We suggest that AEDs, because of their serotonergic properties, may induce SS, especially in patients who are on another serotonergic agent.

Aggression in correctional and psychiatric settings is relatively common and has a negative effect on physical and mental health both among inmates/clients and staff, as well as organizational-level functioning. The aim of the present study was to critically review the evidence on the effectiveness of nutritional supplements in reducing aggression and violence to contribute to a better understanding of options available for managing aggressive behaviors in adults. The EMBASE, MEDLINE, PsycINFO, Cochrane Library, and PubMed databases were searched for effectiveness studies published in English anytime up until March 2020. Study quality was assessed using the Mixed Methods Appraisal Tool. Altogether, 14 studies met inclusion criteria; 2 investigated micronutrients, 10 examined macronutrients, while further 2 examined a combination of micro and macronutrients. Out of the 14 studies, 5 reported a beneficial effect of nutritional supplementation (omega-3 fatty acids, vitamins/minerals, S-adenosyl-l-methionine, or tryptophan). Five studies did not report a significant beneficial effect of nutritional supplementation (omega-3 fatty acids, folic acid, tryptophan, broad range supplement containing vitamins and fatty acids, and fatty acids in augmentation with valproic acid), while four studies reported mixed effects (on l-tryptophan, broad-range micronutrient formula, folic acid, and omega-3 fatty acids). The results overall indicated that research in this area is in its infancy: very few studies examined the same composition of nutritional supplementation and when they did so the results were contradictory. The methodological shortcoming of existing studies and directions for future research are discussed to facilitate high-quality research in this evolving area of nutritional psychiatry.

Review
BACKGROUND
Comprehensive data on the efficacy and tolerability of antiepileptic drugs (AED) treatment in glioma patients with epilepsy are currently lacking. In this systematic review, we specifically assessed the efficacy of AEDs in patients with a grade II-IV glioma.
METHODS
Electronic databases PubMed/MEDLINE, EMBASE, Web of Science, and Cochrane Library were searched up to June 2020. Three different outcomes for both mono- and polytherapy were extracted from all eligible articles: (i) seizure freedom; (ii) ≥50% reduction in seizure frequency; and (iii) treatment failure. Weighted averages (WA) were calculated for outcomes at 6 and 12 months.
RESULTS
A total of 66 studies were included. Regarding the individual outcomes on the efficacy of monotherapy, the highest seizure freedom rate at 6 months was with phenytoin (WA = 72%) while at 12-month pregabalin (WA = 75%) and levetiracetam (WA = 74%) showed highest efficacy. Concerning ≥50% seizure reduction rates, levetiracetam showed highest efficacy at 6 and 12 months (WAs of 82% and 97%, respectively). However, treatment failure rates at 12 months were highest for phenytoin (WA = 34%) and pregabalin (41%). When comparing the described polytherapy combinations with follow-up of ≥6 months, levetiracetam combined with phenytoin was most effective followed by levetiracetam combined with valproic acid.
CONCLUSION
Given the heterogeneous patient populations and the low scientific quality across the different studies, seizure rates need to be interpreted with caution. Based on the current limited evidence, with the ranking of AEDs being confined to the AEDs studied, levetiracetam, phenytoin, and pregabalin seem to be most effective as AED monotherapy in glioma patients with epilepsy, with levetiracetam showing the lowest treatment failure rate, compared to the other AEDs studied.

Clinical Neuropsychiatry Oct 2020We reviewed literature on drugs for bipolar disorders (BD), utilized in ovarian cancer (OC).
OBJECTIVE
We reviewed literature on drugs for bipolar disorders (BD), utilized in ovarian cancer (OC).
METHOD
We adhered to the Preferred Reporting Items for Systematic Review and Meta-Analyses (PRISMA) guidelines in completion of this systematic review.
RESULTS
We identified 73 papers. Thirty-two studies were finally included. BD is rarely diagnosed in OC patients. Limited finding from case reports is available. Drugs used to treat BD (mainly lithium and valproic acid) have been extensively studied in add-on to chemotherapy for treatment-resistant OC cells or in animal models, with promising results in vitro but not in vivo.
CONCLUSIONS
The clinical underestimation of BD in OC has leaded to the almost complete absence of evidences for a soundly based clinical guidance in this field. There is a urgent need for a systematic multi-disciplinary approach to OC.

Meta-Analysis Review
OBJECTIVES
This study provides a systematic review and meta-analysis of randomized controlled trials (RCTs) investigating the safety and efficacy of lithium in amyotrophic lateral sclerosis (ALS) patients.
METHODS
PubMed, Web of Science, Cochrane CENTRAL, Scopus, and Your Journals@Ovid were searched up to 9 December 2022. RCTs investigating lithium, either alone or with any supplement, in ALS patients were included. Meta-analysis was performed using RevMan and results are presented in forest plot.
RESULTS
Four RCTs with 469 patients met the inclusion criteria and were included in our study. Lithium doses varied among the included studies and one study used a combined therapy of lithium with valproate. Meta-analysis showed no difference between lithium and placebo regarding severe adverse events (odds ratio = 1.13, 95% confidence interval: 0.73 to 1.75, P = 0.58). No significant differences were observed with regard to survival rate between the two groups (hazard ratio = 0.95, 95% confidence interval: 0.65 to 1.37, P = 0.77). There were also no significant differences between the two groups with regard to average changes of revised amyotrophic lateral sclerosis functional rating scale (P = 0.35) and forced vital capacity percentage predicted (P = 0.73). Subgroup analysis showed no significant differences regarding all investigated outcomes either for lithium alone or lithium with valproate.
CONCLUSION
Current evidence suggests a safety profile with no benefit of lithium for ALS. However, given the limited number of RCTs and the safety findings, we recommend further well-designed RCTs to investigate lithium and valproate in ALS patients.

BACKGROUND
Valproic acid (VPA) is a common antiepileptic drug used to treat both generalized and partial epilepsy. Although there is increasing evidence to suggest that gene polymorphisms are associated with interindividual variability of VPA metabolism, the results are debatable. Therefore, in the present study, we conducted a meta-analysis to evaluate the correlation between gene polymorphisms and adjusted plasma VPA concentration.
METHODS
The EMBASE, MEDLINE, and Cochrane Library databases were searched to obtain relevant studies. Eligible articles were reviewed, and data extraction was performed. We calculated 95% confidence intervals (CIs) and mean differences (MDs) to assess the strength of the relationship of gene polymorphisms with adjusted plasma VPA concentration.
RESULTS
The meta-analysis included 6 studies involving 847 patients with epilepsy. The pooled analysis showed that the A1075C (AA AC) polymorphism was related to the adjusted plasma concentration of VPA (P=0.02, I= 82%). Additionally, the AC phenotype statistically significantly increased the adjusted plasma VPA concentration in children compared with the mixed age subgroup (P=0.04, I= 48%). A similar association was observed between the AC phenotype for Asians (P<0.00001, I=0%) but not for Caucasians (P=0.34, I=87%).
DISCUSSION
Age might be a crucial covariate influencing the dosage-adjusted VPA concentration in patients with epilepsy. A reduced VPA dosage may be recommendable for children, particularly Asian children, who are A1075C AC carriers. Further studies could provide high-quality evidence to confirm the correlation between VPA pharmacokinetics and A1075C polymorphisms.

Meta-Analysis Review
OBJECTIVE
To estimate the safety and efficacy of sodium valproate combined with levetiracetam in paediatric patients with epilepsy based on randomized controlled trials (RCTs).
METHODS
The Cochrane Library, PubMed, Web of Science, Chinese Journal Full-Text Database (CNKI), WANGFANG DATA and Sino Med were searched between January 1946 and May 2021. The included literature was randomized controlled clinical trials focusing on sodium valproate combined with levetiracetam in paediatric patients with epilepsy. Two evaluators separately collected the data based on the retrieval strategy, filtered the literature in accordance with the inclusion and exclusion criteria, and summarized the literature that satisfied the criteria. The statistical programme used for the meta-analysis was Stata V14.0.
RESULTS
Of 577 original titles screened, data were extracted from 7 studies (617 participants). Compared with sodium valproate alone or sodium valproate combined with topiramate, the application of sodium valproate combined with levetiracetam in the treatment of paediatric epilepsy significantly improved the overall therapeutic effect (RR=1.24, 95% CI: 1.16 to 1.33, p=0.927). The observation group significantly reduced the occurrence of adverse drug reactions (ADRs) (RR=0.54, 95% CI: 0.37 to 0.79, p=0.602). Egger's regression test of the overall therapeutic effect showed no potential publication bias (p=0.122).
CONCLUSION
Based on this meta-analysis, compared with sodium valproate alone or sodium valproate with topiramate, the application of sodium valproate combined with levetiracetam in the treatment of paediatric epilepsy can significantly improve the overall therapeutic effect and simultaneously reduce the occurrence of ADR. Therefore, we recommend sodium valproate combined with levetiracetam for the therapy of paediatric patients with epilepsy.

AIMS
Autism is a multifaceted developmental disorder of the nervous system, that necessitates novel therapeutic approaches beyond traditional medications and psychosomatic therapy, such as appropriate sensory integration training. This systematic mapping review aims to synthesize existing knowledge on enriching environmental interventions as an alternative avenue for improving autism, guiding future research and practice.
METHOD
A comprehensive search using the terms ASD and Enriched Environment was conducted across PubMed, EMBASE, ISI, Cochrane, and OVID databases. Most of the literature included in this review was derived from animal model experiments, with a particular focus on assessing the effect of EE on autism-like behavior, along with related pathways and molecular mechanisms. Following extensive group discussion and screening, a total of 19 studies were included for analysis.
RESULTS
Enriched environmental interventions exhibited the potential to induce both behavioral and biochemical changes, ameliorating autism-like behaviors in animal models. These improvements were attributed to the targeting of BDNF-related pathways, enhanced neurogenesis, and the regulation of glial inflammation.
CONCLUSION
This paper underscores the positive impact of enriched environmental interventions on autism through a review of existing literature. The findings contribute to a deeper understanding of the underlying brain mechanisms associated with this intervention.

Review
BACKGROUND
Recent position papers and guidelines encourage women with epilepsy (WWE) to exclusively breastfeed their infants because the benefits to their infants outweigh the potential adverse effects caused by exposure to antiseizure medications (ASMs).
OBJECTIVE
The objectives of this review were: to evaluate concentrations of ASMs in breastmilk of lactating WWE, qualitatively synthesize evidence that can be used to estimate theoretical doses as estimated daily intake (EDI) and relative infant dose (RID) of ASMs, and to evaluate potential risks to infants as a result of exposure to ASMs from breastmilk.
METHODS
This systematic review was registered in the International Prospective Register of Systematic Reviews (PROSPERO) as CRD42020223645. The databases: MEDLINE/PubMed, EMBASE, CINAHL/EBSCO, COCHRANE, SpringerLink, ScienceDirect, Summon, WHO International Clinical Trials Registry Platform, and SCOPUS were systematically searched. A qualitative synthesis was adopted in this study.
RESULTS
A total of 15 records were included in this systematic review. The included studies reported levels of 8 ASMs in the breastmilk of WWE. The highest RIDs of carbamazepine, lamotrigine, primidone, phenobarbital, gabapentin, valproic acid, ethosuximide, levetiracetam, and topiramate were 3.70%, 36.33%, 4.96%, 3.15%, 4.37%, 1.90%, 31.49%, 12.50%, and 12.18%, respectively. Breastfeeding might be limited or even discontinued when signs of excessive sedation/drowsiness and/or poor weight gain are evident on infants exposed to primidone and phenobarbital, ethosuximide/primidone, or ethosuximide/phenobarbital.
CONCLUSIONS
Concentrations of ASMs can be detected in breastmilk of WWE and plasma/serum of infants exposed via breastmilk. Healthcare providers and WWE might use the findings of this study to make informed decisions on the safety of breastfeeding while taking ASMs.
