Review
Hyponatremia is the most common fluid and electrolyte imbalance in hospitalized patients. Among hyponatremia causes, syndrome of inappropriate antidiuretic hormone secretion is a condition characterized by excessive release of antidiuretic hormone from the pituitary gland or nonpituitary sources. One of the most common drugs associated with hyponatremia is selective serotonin reuptake inhibitors, especially in elderly patients. Therefore, distinct therapeutic alternatives are essential for patients having risk factors for hyponatremia or syndrome of inappropriate antidiuretic hormone secretion development. The present article aims to review the available literature evaluating mirtazapine-induced hyponatremia or syndrome of inappropriate antidiuretic hormone secretion in adult or elderly patients in order to determine the incidence of these adverse effects and analyze the existence of any correlation between the administered dose of mirtazapine and serum sodium levels. A systematic search was conducted, using key terms from the research topic, their synonyms, and Boolean/logic operators. From this evidence pool, inclusion and exclusion criteria were applied. We abstracted population characteristics and clinical endpoints. Relevant data from selected studies was abstracted and subject to statistical analysis. A total sample size of 30,851 patients treated with mirtazapine was included. Mirtazapine-induced hyponatremia incidence was 3.26% (95% CI 3.06-3.45%), with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) the most probable underlying cause. Among case series and case reports evaluated (n=7), hyponatremia and SIADH were more frequent in female patients (71.4%) and the most frequent clinical manifestations included confusion (57%), somnolence (42%), and altered speech (28%). Mean serum sodium levels were (117 mEq/L, ranging from 113-130 mEq/L). The average time lapse between mirtazapine administration and clinical findings was 34 days. The Spearman's rank correlation coefficient between mirtazapine dosage and serum sodium levels was -0.3181 with a p-value >0.05. In conclusion, mirtazapine presents a moderate risk of hyponatremia and should be considered as an alternative therapy in patients requiring antidepressants with risk factors for this preventable adverse effect.

Meta-Analysis Review
BACKGROUND
Amphetamine-type stimulants continue to dominate the global drug markets. Despite this, no pharmacotherapy has been approved for treatment of amphetamine and methamphetamine use disorder (AMD). We evaluate the efficacy of mirtazapine in the treatment of AMD, given emerging evidence that it may alleviate methamphetamine and amphetamine (MA/A) cravings and withdrawals.
METHODS
We searched five databases from inception until January 28, 2021 for studies with a comparator group evaluating mirtazapine for treatment of AMD. We collected data on reduction in MA/A use, treatment retention, sexual behaviors, depression symptoms, cravings and adverse events. We assessed certainty of evidence using GRADE. Where appropriate, we conducted fixed-effect meta-analyses weighted by inverse variance and calculated the absolute risk reduction.
RESULTS
Among the 206 studies screened, we included two parallel-arm placebo-controlled RCTs conducted among cis-gender men and transgender women (n = 180). We found that mirtazapine use likely results in a small reduction of methamphetamine use compared to placebo after 12-weeks (relative risk [RR]=0.81, 95% confidence interval [CI]: 0.63, 1.03; n = 133; moderate certainty evidence due to imprecision). We also found that the use of mirtazapine probably does not improve retention in treatment (RR=1.01, 95% CI: 0.91, 1.12; n = 180; moderate certainty evidence) or depression symptom severity (mean difference [MD]=0.45, 95% CI: -2.88, 3.78; n = 53; moderate certainty evidence). There were no serious adverse events.
CONCLUSIONS AND RELEVANCE
Mirtazapine probably results in a small reduction in continued methamphetamine use among cisgender men and transgender women with AMD, but probably does not improve patients' retention in treatment or depression symptom severity.

Meta-Analysis Review
Psychotic symptoms of dementia are highly prevalent and lead to poor medical outcomes and substantial dysfunction. To date, which drug to use remains controversial without a summary of all direct or indirect comparisons of pharmacotherapy. Therefore, we conducted a systematic review with pairwise and network meta-analysis to examine efficacy and tolerability outcomes of pharmacological treatments in dementia patients. MEDLINE, Cochrane Library, EMBASE, and PubMed were searched systematically up to August 31, 2020. We included trials of cholinesterase inhibitors (ChEIs), memantine, antipsychotics, antidepressants, and mood stabilizers, with final approval from the U.S. Food and Drug Administration. We ranked the comparative effects of all drugs against placebo with surface under the cumulative ranking (SUCRA) probabilities. This analysis is based on 34 trials, which included 10,415 patients randomly assigned to 15 commonly used drug regimens. Donepezil (standardized mean difference [SMD] -0.30, 95% credible interval [CrI] -0.50 to -0.12; SUCRA, 0.85), memantine (SMD -0.20, 95%CrI -0.34 to -0.07; SUCRA, 0.68) and aripiprazole (SMD -0.17, 95% CrI -0.32 to -0.02; SUCRA, 0.62) showed greater benefit than placebo, and with relatively good tolerability in network meta-analyses. Risperidone was also found to be more efficacious than placebo (SMD -0.16, 95% CrI -0.28 to -0.05; SUCRA, 0.60), but with poor tolerability (odds ratios [OR] 1.50, 95% CrI 1.06-2.26). Donepezil, memantine, haloperidol, aripiprazole and risperidone were more efficacious than quetiapine (SMDs ranged from -0.36 to -0.22). Besides, donepezil, memantine and mirtazapine were more efficacious than sertraline (SMDs ranged from -0.47 to -0.36). Most of the results were rated as "low" to "very low". Several effective treatment choices for psychotic symptoms are available across drug classes. Donepezil, memantine and aripiprazole are probably the appropriate options to consider when a pharmacological treatment is indicated. Given the limitations of the meta-analytic approach and the low methodological quality of the majority of studies, our results should be cautiously interpreted.

Meta-Analysis Review
OBJECTIVE
To compare the efficacy and discontinuation of augmentation agents in adult patients with treatment-resistant depression (TRD). We conducted a systematic review and network meta-analyses (NMA) to combine direct and indirect comparisons of augmentation agents.
METHODS
We included randomized controlled trials comparing one active drug with another or with placebo following a treatment course up to 24 weeks. Nineteen agents were included: stimulants, atypical antipsychotics, thyroid hormones, antidepressants, and mood stabilizers. Data for response/remission and all-cause discontinuation rates were analyzed. We estimated effect-size by relative risk using pairwise and NMA with random-effects model.
RESULTS
A total of 65 studies (N = 12,415) with 19 augmentation agents were included in the NMA. Our findings from the NMA for response rates, compared to placebo, were significant for: liothyronine, nortriptyline, aripiprazole, brexpiprazole, quetiapine, lithium, modafinil, olanzapine (fluoxetine), cariprazine, and lisdexamfetamine. For remission rates, compared to placebo, were significant for: thyroid hormone(T4), aripiprazole, brexpiprazole, risperidone, quetiapine, and olanzapine (fluoxetine). Compared to placebo, ziprasidone, mirtazapine, and cariprazine had statistically significant higher discontinuation rates. Overall, 24% studies were rated as having low risk of bias (RoB), 63% had moderate RoB and 13% had high RoB.
LIMITATIONS
Heterogeneity in TRD definitions, variable trial duration and methodological clinical design of older studies and small number of trials per comparisons.
CONCLUSIONS
This NMA suggests a superiority of the regulatory approved adjunctive atypical antipsychotics, thyroid hormones, dopamine compounds (modafinil and lisdexamfetamine) and lithium. Acceptability was lower with ziprasidone, mirtazapine, and cariprazine. Further research and head-to-head studies should be considered to strengthen the best available options for TRD.

Review
The aim of the article is to review systematically current researches investigating the relationship between intrauterine exposure to antidepressants and neonatal hypoglycemia. This paper included studies published in electronic databases from January 2005 to July 2020. The searched keywords were as follows: antidepressants, pregnancy, selective serotonin reuptake inhibitors (SSRIs), citalopram, fluoxetine, paroxetine, escitalopram, sertraline, fluvoxamine, selective serotonin-norepinephrine reuptake inhibitors (SNRIs), venlafaxine, tricyclic antidepressants (TCAs), neonatal outcomes, neonatal hypoglycemia, imipramine, clomipramine, amitriptyline, bupropion, trazodone, and mirtazapine. This review examined 10 relevant studies. The odds ratio/risk ratio reported in the studies were 1.33-1.73 for any antidepressant, 1.30-1.35 for SSRI, 1.42-2.11 for SNRI, and 2.07 for TCAs. The risk of neonatal hypoglycemia in infants exposed to maternal TCAs appears to be slightly higher compared to infants exposed to maternal SSRIs. Data from current studies consistently show that exposure to maternal antidepressants during pregnancy may be related to increased risk of neonatal hypoglycemia in infants.

BACKGROUND/PURPOSE
Tricyclic antidepressants (TCAs) are still widely used and are available to purchase without prescription in some countries. Awareness of adverse cutaneous drug reactions is essential.
METHOD
We reported a case of photo-distributed hyperpigmentation due to imipramine and carried out a systematic search of the related articles using the search terms "tricyclic antidepressants" or "tricyclic antidepressive agents", and "hyperpigmentation" or "photosensitivity disorder". Fifty non-duplicate citations were identified of which 28 articles which were independently assessed in full. The review was registered in PROSPERO, CRD42018107338.
RESULTS
The remaining 25 articles met our inclusion criteria. Photo-distributed hyperpigmentation tricyclic antidepressant-induced photosensitivity reactions (TIPs) was the most common presentation. In 21 cases, this presented as an asymptomatic discolouration of exposed sites. Imipramine (81%), amitriptyline (9.5%), desipramine hydrochloride (4.8%) and mirtazapine (4.8%) were reported to be the culprit drugs. Nineteen were female with a mean age at presentation of 55 years. Mean duration from commencing the culprit drug until the development of discolouration was 10.4 years. Mean daily dose was 222.7 mg for imipramine. Histology was characteristic with golden-brown or brownish granules deposited in dermis. Staining for Masson-Fontana and MEL-5 was positive in all cases. Phototesting had not been done in cases prior to ours (negative 3 months after discontinuation of imipramine). Three further reports of suspected TIP presented with non-specific and eczematous eruption. The two presentations were reported along with systemic problems (thrombocytopenia and hepatic injury).
CONCLUSIONS
This systematic review highlights the characteristic features of exposed site hyperpigmentation of TCA-induced photosensitivity occurring after prolonged drug exposure in many cases.

Comparative Study Meta-Analysis
BACKGROUND
Depression is considered as one of the most common neuropsychiatric symptoms (NPS) in Alzheimer's disease (AD) patients. Prescription of antidepressants is a current clinical practice well-established as the first-line treatment for such patients. Our study was aimed at systematically examining the evidence on the efficacy of antidepressants in the treatment of depression in AD patients.
METHODS
We conducted a network meta-analysis of randomized controlled trials retrieved by systematic search of the Cochrane Central Register of Controlled Trials, PubMed, Embase, and CNKI databases. Primary outcomes included mean depression score and safety. Secondary outcomes were cognition. The surface under the cumulative ranking curve was performed to estimate a ranking probability for different treatments.
RESULTS
A total of 25 studies including 14 medications met the inclusion criteria. Compared with placebo, only mirtazapine (standard mean deviation [SMD], -1.94; 95% confidence interval [CI], -3.53 to -0.36; < 0.05) and sertraline (SMD, -1.16; 95% CI, -2.17 to -0.15; < 0.05) showed a slightly better effect in treating symptoms of depression. Clomipramine increased risk of adverse events than placebo (odds ratio, 3.01; 95% CI, 1.45 to 4.57; < 0.05). In terms of cognitive function, there was no statistically significant difference between antidepressants and placebo.
CONCLUSION
Overall, in the short-term treatment, these data suggest that commonly used antidepressants sertraline and mirtazapine should be considered as an alternative treatment for depression in AD patients. However, more high-quality trials with large samples and longer following-up are proposed.

Meta-Analysis
BACKGROUND
Major depressive disorders have a significant impact on children and adolescents, including on educational and vocational outcomes, interpersonal relationships, and physical and mental health and well-being. There is an association between major depressive disorder and suicidal ideation, suicide attempts, and suicide. Antidepressant medication is used in moderate to severe depression; there is now a range of newer generations of these medications.
OBJECTIVES
To investigate, via network meta-analysis (NMA), the comparative effectiveness and safety of different newer generation antidepressants in children and adolescents with a diagnosed major depressive disorder (MDD) in terms of depression, functioning, suicide-related outcomes and other adverse outcomes. The impact of age, treatment duration, baseline severity, and pharmaceutical industry funding was investigated on clinician-rated depression (CDRS-R) and suicide-related outcomes.
SEARCH METHODS
We searched the Cochrane Common Mental Disorders Specialised Register, the Cochrane Library (Central Register of Controlled Trials (CENTRAL) and Cochrane Database of Systematic Reviews (CDSR)), together with Ovid Embase, MEDLINE and PsycINFO till March 2020.
SELECTION CRITERIA
Randomised trials of six to 18 year olds of either sex and any ethnicity with clinically diagnosed major depressive disorder were included. Trials that compared the effectiveness of newer generation antidepressants with each other or with a placebo were included. Newer generation antidepressants included: selective serotonin reuptake inhibitors; selective norepinephrine reuptake inhibitors (SNRIs); norepinephrine reuptake inhibitors; norepinephrine dopamine reuptake inhibitors; norepinephrine dopamine disinhibitors (NDDIs); and tetracyclic antidepressants (TeCAs).
DATA COLLECTION AND ANALYSIS
Two reviewers independently screened titles/abstracts and full texts, extracted data, and assessed risk of bias. We analysed dichotomous data as Odds Ratios (ORs), and continuous data as Mean Difference (MD) for the following outcomes: depression symptom severity (clinician rated), response or remission of depression symptoms, depression symptom severity (self-rated), functioning, suicide related outcomes and overall adverse outcomes. Random-effects network meta-analyses were conducted in a frequentist framework using multivariate meta-analysis. Certainty of evidence was assessed using Confidence in Network Meta-analysis (CINeMA). We used "informative statements" to standardise the interpretation and description of the results.
MAIN RESULTS
Twenty-six studies were included. There were no data for the two primary outcomes (depressive disorder established via clinical diagnostic interview and suicide), therefore, the results comprise only secondary outcomes. Most antidepressants may be associated with a "small and unimportant" reduction in depression symptoms on the CDRS-R scale (range 17 to 113) compared with placebo (high certainty evidence: paroxetine: MD -1.43, 95% CI -3.90, 1.04; vilazodone: MD -0.84, 95% CI -3.03, 1.35; desvenlafaxine MD -0.07, 95% CI -3.51, 3.36; moderate certainty evidence: sertraline: MD -3.51, 95% CI -6.99, -0.04; fluoxetine: MD -2.84, 95% CI -4.12, -1.56; escitalopram: MD -2.62, 95% CI -5.29, 0.04; low certainty evidence: duloxetine: MD -2.70, 95% CI -5.03, -0.37; vortioxetine: MD 0.60, 95% CI -2.52, 3.72; very low certainty evidence for comparisons between other antidepressants and placebo). There were "small and unimportant" differences between most antidepressants in reduction of depression symptoms (high- or moderate-certainty evidence). Results were similar across other outcomes of benefit. In most studies risk of self-harm or suicide was an exclusion criterion for the study. Proportions of suicide-related outcomes were low for most included studies and 95% confidence intervals were wide for all comparisons. The evidence is very uncertain about the effects of mirtazapine (OR 0.50, 95% CI 0.03, 8.04), duloxetine (OR 1.15, 95% CI 0.72, 1.82), vilazodone (OR 1.01, 95% CI 0.68, 1.48), desvenlafaxine (OR 0.94, 95% CI 0.59, 1.52), citalopram (OR 1.72, 95% CI 0.76, 3.87) or vortioxetine (OR 1.58, 95% CI 0.29, 8.60) on suicide-related outcomes compared with placebo. There is low certainty evidence that escitalopram may "at least slightly" reduce odds of suicide-related outcomes compared with placebo (OR 0.89, 95% CI 0.43, 1.84). There is low certainty evidence that fluoxetine (OR 1.27, 95% CI 0.87, 1.86), paroxetine (OR 1.81, 95% CI 0.85, 3.86), sertraline (OR 3.03, 95% CI 0.60, 15.22), and venlafaxine (OR 13.84, 95% CI 1.79, 106.90) may "at least slightly" increase odds of suicide-related outcomes compared with placebo. There is moderate certainty evidence that venlafaxine probably results in an "at least slightly" increased odds of suicide-related outcomes compared with desvenlafaxine (OR 0.07, 95% CI 0.01, 0.56) and escitalopram (OR 0.06, 95% CI 0.01, 0.56). There was very low certainty evidence regarding other comparisons between antidepressants.
AUTHORS' CONCLUSIONS
Overall, methodological shortcomings of the randomised trials make it difficult to interpret the findings with regard to the efficacy and safety of newer antidepressant medications. Findings suggest that most newer antidepressants may reduce depression symptoms in a small and unimportant way compared with placebo. Furthermore, there are likely to be small and unimportant differences in the reduction of depression symptoms between the majority of antidepressants. However, our findings reflect the average effects of the antidepressants, and given depression is a heterogeneous condition, some individuals may experience a greater response. Guideline developers and others making recommendations might therefore consider whether a recommendation for the use of newer generation antidepressants is warranted for some individuals in some circumstances. Our findings suggest sertraline, escitalopram, duloxetine, as well as fluoxetine (which is currently the only treatment recommended for first-line prescribing) could be considered as a first option. Children and adolescents considered at risk of suicide were frequently excluded from trials, so that we cannot be confident about the effects of these medications for these individuals. If an antidepressant is being considered for an individual, this should be done in consultation with the child/adolescent and their family/caregivers and it remains critical to ensure close monitoring of treatment effects and suicide-related outcomes (combined suicidal ideation and suicide attempt) in those treated with newer generation antidepressants, given findings that some of these medications may be associated with greater odds of these events. Consideration of psychotherapy, particularly cognitive behavioural therapy, as per guideline recommendations, remains important.

Autism Spectrum Disorder (ASD) is a severe and lifelong neurodevelopmental disorder, with high social costs and a dramatic burden on the quality of life of patients and family members. Despite its high prevalence, reaching 1/54 children and 1/45 adults in the United States, no pharmacological treatment is still directed to core symptoms of ASD, encompassing social and communication deficits, repetitive behaviors, restricted interests, and abnormal sensory processing. The purpose of this review is to provide an overview of the state-of-the-art of psychopharmacological therapy available today for ASD in children and adolescents, in order to foster best practices and to organize new strategies for future research. To date, atypical antipsychotics such as risperidone and aripiprazole represent the first line of intervention for hyperactivity, impulsivity, agitation, temper outbursts or aggression towards self or others. Tricyclic antidepressants are less prescribed because of uncertain efficacy and important side effects. SSRIs, especially fluoxetine and sertraline, may be effective in treating repetitive behaviors (anxiety and obsessive-compulsive symptoms) and irritability/agitation, while mirtazapine is more helpful with sleep problems. Low doses of buspirone have shown some efficacy on restrictive and repetitive behaviors in combination with behavioral interventions. Stimulants, and to a lesser extent atomoxetine, are effective in reducing hyperactivity, inattention and impulsivity also in comorbid ASD-ADHD, although with somewhat lower efficacy and greater incidence of side effects compared to idiopathic ADHD. Clonidine and guanfacine display some efficacy on hyperactivity and stereotypic behaviors. For several other drugs, case reports and open-label studies suggest possible efficacy, but no randomized controlled trial has yet been performed. Research in the pediatric psychopharmacology of ASD is still faced with at least two major hurdles: (a) Great interindividual variability in clinical response and side effect sensitivity is observed in the ASD population. This low level of predictability would benefit from symptom-specific treatment algorithms and from biomarkers to support drug choice; (b) To this date, no psychoactive drug appears to directly ameliorate core autism symptoms, although some indirect improvement has been reported with several drugs, once the comorbid target symptom is abated.

Pharmacologic interventions for antidepressant-induced sexual dysfunction: a systematic review and network meta-analysis of trials using the Arizona sexual experience scale.
BACKGROUND
Despite the prevalence of antidepressant-related sexual side effects, comparisons of treatments for these problematic side effects are lacking.
METHODS
To address this, we performed a systematic review and Bayesian network meta-analysis to compare interventions for antidepressant-induced sexual dysfunction in adults. Using PubMed and clinicaltrials.gov, we identified published and unpublished prospective treatment trials from 1985 to September 2020 (primary outcome: the Arizona sexual experience scale [ASEX] score). The quality of evidence was assessed using the Grading of Recommendations Assessment, Development, and Evaluation framework.
RESULTS
We identified 57 citations (27 randomized controlled trials, 66 treatment arms, 27 open-label trials, and 3 crossover trials) that evaluated 33 interventions (3108 patients). In the systematic review, 44% (25/57) of trials reported successful interventions; this was more common in open-label (70%, 19/27) compared to placebo-controlled studies (22%, 6/27). In the meta-analysis of placebo-controlled studies that used the ASEX (N = 8), pycnogenol was superior to placebo (standardized mean difference: -1.8, 95% credible interval [CrI]: [-3.7 to 0.0]) and there was evidence that, at a 6% threshold, sildenafil improved sexual dysfunction (standardized mean difference: -1.2, 95% CrI [-2.5 to 0.1]). In the meta-analysis including single-arm studies (15 studies), treatment response was more common with sildenafil, tianeptine, maca, tiagabine, and mirtazapine compared to placebo, but these differences failed to reach statistical significance.
CONCLUSIONS
While heterogeneity across randomized controlled trials complicates identifying the single best intervention, multiple trials suggest that sildenafil ameliorates antidepressant-induced sexual dysfunction. More randomized controlled trials are needed to examine the putative efficacy of other interventions.
