RESUMO
BACKGROUND: Psilocybin-assisted psychotherapy (PAP) is a promising treatment option for depression, with randomized controlled trials (RCTs) providing preliminary support for its safety and efficacy. However, there is a lack of consistency across existing treatment protocols and psychotherapeutic approaches. The objective of this review is to summarize and compare current psychotherapy methods of PAP in treating depression and distress in life-threatening illnesses. We sought to comprehensively summarize published psychotherapy protocols from clinical trials to provide insights for future practices. METHODS: A systematic search of four databases (Embase, MEDLINE, PsycINFO, CINAHL) for data relating to psychotherapy protocols was conducted by two independent reviewers. RESULTS: In total, our search identified 1869 articles; after removing duplicates, we screened 1107 articles. We included 70 articles in the full-text review and determined that 28 were eligible for the final review. All protocols include sessions before (preparatory) and after (integration) the psychedelic dosing session with supportive monitoring. However, there was substantial variability and inconsistencies in all other aspects of therapy protocols (e.g., duration and number of sessions, model of therapy). Additionally, significant limitations were identified in the frequent need for more clarity in the description of therapeutic approaches. CONCLUSION: In published clinical trials, PAP has consisted of preparation, supportive dosing, and integration sessions. Beyond this basic framework, significant heterogeneity and lack of clarity were identified in reported psychotherapy protocols, meaning a validated and universally agreed upon protocol for PAP currently does not exist. Future studies should more clearly define and report psychotherapeutic components to identify the safest and most efficacious approaches to PAP.

BACKGROUND: Converging lines of evidence indicate that ketamine is a rapid antidepressant for individuals with treatment-resistant depression. Hitherto, no reliable a priori predictors of ketamine response have been reported. Pharmacogenetic biomarkers have yielded mixed results regarding potential candidate genes associated with ketamine's biochemistry as reliable predictors of response. AIMS: No studies have examined the effects of Val66Met and CYP2B6 genotypes on patients receiving repeated infusions of intravenous ketamine. METHODS: In all, 85 participants with major depressive disorder who had previously received four infusions of intravenous ketamine were recruited to the foregoing study. Buccal swabs were collected and genotype variants across the Val66Met and CYP2B6 genes were analyzed. A repeated measures mixed linear model was used to assess change in depressive symptoms, suicidality, and anxiety, correcting for sex and age. Multiple regression was run to determine whether these genetic markers were associated with treatment efficacy for depressive severity, suicidal ideation, anxiolytic response, and degree of dissociation to intravenous ketamine. RESULTS: Participants experienced significant overall reductions in depression, suicide, and anxiety. Overall, 25% met the response criteria and 15% met the remission criteria. However, Val66Met and CYP2B6 did not significantly predict changes in symptoms of depression, suicide, anxiety, or average dissociation. CONCLUSIONS: This study contributes to the growing literature that ketamine efficacy is unlikely to be predicted by single genes, and a pleiotropic approach may likely be necessary for developing reliable predictors of clinical benefits.

Converging evidence has suggested that treatment augmentation with a second-generation atypical antipsychotic (SGA) may improve treatment outcomes in major depressive disorder (MDD) patients after an incomplete response to a first-line antidepressant. Cariprazine is a recently approved SGA for MDD augmentation. Herein, we evaluate both continuous (ie, change in depressive symptom severity scores over time) and categorical (ie, remission and response rates) outcomes. Following a full-text review, four randomized controlled trials (RCTs) were included in our meta-analysis, while five studies were included for a qualitative review. Risk ratios (RRs) were calculated for all included randomized controlled studies to determine the relative response and remission rates of cariprazine compared to placebo augmentation. The RR for all-cause dropout was also determined as a proxy for overall acceptability. Two studies found a statistically significant treatment response using cariprazine augmentation. One study observed depressive symptom remission for cariprazine compared to placebo. Our random-effects model revealed moderate antidepressant effects of cariprazine, with a standardized mean difference (SMD) in Montgomery-Åsberg Depression Rating Scale (MADRS) scores of -1.79 (95% CI): -2.89, -0.69). Our pooled response RR and remission RR were calculated as 1.21 (95% CI: 1.05, 1.39, P=0.008) and 0.99 (95% CI: 0.84, 1.17, P=0.91), respectively. The RR for response was statistically significant (P<0.05). However, the RR for remission was not statistically significant. The findings from our meta-analysis include a variable magnitude of effects. Evidence suggests cariprazine may be an effective treatment for MDD; however, further results are needed to clarify this relation.
RESUMO
The aim of this review was to determine the effect of psilocybin on depressive symptoms in patients diagnosed with life-threatening illnesses or major depressive disorder. Systematic searches were conducted to search for randomized clinical trials and open-label trials that evaluated depression symptoms after psilocybin therapy. Data was pooled using a random-effects model. The primary outcome was the standardized mean difference (SMD) in depression severity, determined by calculating the change in depression ratings from baseline to the primary endpoint in the psilocybin arm versus the control arm. The literature search yielded 1734 studies, and 13 studies (n = 686) were included in either qualitative and/or quantitative analyses. The meta-analysis included 9 studies (pooled n = 596) and yielded a large effect size in favour of psilocybin (SMD = -0.78; p<0.001). Risk ratios for response and remission were large and significant in favour of psilocybin. A review of open-label trials showed robust decreases in depressive symptoms following psilocybin administration. These findings provide preliminary evidence for antidepressant efficacy with psilocybin-assisted psychotherapy, however, further studies are needed to evaluate safety and efficacy and to optimize treatment protocols.

Background: The therapeutic potential of subanesthetic doses of ketamine appears promising in unipolar depression; however, its effectiveness in treating bipolar depression (BD) remains uncertain. Objective: This systematic review aimed to summarize findings on the use of ketamine for the treatment of BD by assessing its efficacy, safety, and tolerability. Design: Systematic review. Methods: We conducted a systematic review of studies that investigated the use of ketamine for adults with BD. We searched PubMed and Embase for relevant randomized-controlled trials, open-label trials, and retrospective chart analyses published from inception to 13 March 2023. Results: Eight studies were identified [pooled n = 235; mean (SD) age: 45.55 (5.54)]. All participants who received intravenous (IV) ketamine were administered a dose of 0.5-0.75 mg/kg as an adjunctive treatment to a mood-stabilizing agent, whereas participants who received esketamine were administered a dosage ranging from 28 to 84 mg. Flexible dosing was used in real-world analyses. A total of 48% of participants receiving ketamine achieved a response (defined as ⩾50% reduction in baseline depression severity), whereas only 5% achieved a response with a placebo. Real-world studies demonstrated lower rates of response (30%) compared to the average across clinical trials (63%). Reductions in suicidal ideation were noted in some studies, although not all findings were statistically significant. Ketamine and esketamine were well tolerated in most participants; however, six participants (2% of the overall sample pool, 5 receiving ketamine) developed hypomanic/manic symptoms after infusions. Significant dissociative symptoms were observed at the 40-min mark in some trials. Conclusion: Preliminary evidence suggests IV ketamine as being safe and effective for the treatment of BD. Future studies should focus on investigating the effects of repeated acute and maintenance infusions using a randomized study design.
RESUMO
Objectives: Ketamine is a glutamate N-methyl-D-aspartate receptor antagonist that can be used to treat major depressive disorder by single or repeated infusions. However, the accessibility and scalability of oral ketamine make it preferred over intravenous ketamine. In this systematic review, we aim to evaluate the efficacy, tolerability, and safety of oral ketamine, esketamine and r-ketamine for unipolar and bipolar depression. Materials and methods: Electronic databases were searched from inception to September 2022 to identify relevant articles. Results: Twenty-two studies, including four randomized clinical trials (RCTs), one case series, six case reports, five open-label trials and six retrospective chart review studies involving 2336 patients with depression were included. All included studies reported significant improvement following ketamine administration. Ketamine was well tolerated without serious adverse events. However, RCTs had a high risk of bias due to analysis methods and adverse events monitoring. Ketamine dosage varied from 0.5 to 1.25 mg/kg. The frequency of administration was daily to monthly. Several important limitations were identified, most notably the small number of RCTs. Conclusions: Taken together, preliminary evidence suggests the potential for antidepressant effect of oral ketamine. However, further research with large sample size and long follow-up period is needed to better determine the antisuicidal effect and efficacy in treatment-resistant depression.

BACKGROUND: Postpartum depression (PPD) is a severe, debilitating mood disorder with consequences for both mothers and children, highlighting the need for rapid-acting and effective treatments for PPD. The aim of this narrative review is to synthesize the available literature on the administration of ketamine for PPD and propose ketamine as a viable and advantageous treatment. METHODS: A search was conducted on MEDLINE/PubMed, PsycInfo, and Embase databases from inception to October 10, 2021 for preclinical studies, interventional studies (ie, open-label and randomized controlled trials), as well as systematic reviews and meta-analyses evaluating the use of ketamine in postpartum populations. Completed and ongoing clinical trials were identified on ClinicalTrials.gov. RESULTS: Four clinical trials were identified. Results from this review support additional investigation into ketamine as a potential treatment for PPD. CONCLUSIONS: Ketamine may be a favorable option for treating PPD due to its antidepressive and analgesic effects, short infusion time, and rapid clearance from the maternal bloodstream. However, there is insufficient evidence to support its use in this population, underscoring the importance of additional clinical research investigating ketamine for PPD.

PURPOSE OF REVIEW: Lumateperone (LUM) is the U.S. Food and Drug Administration approved atypical antipsychotic agent for adults with schizophrenia (SCZ) and bipolar depression (for both bipolar I and bipolar II disorder as as monotherapy or as adjunctive treatment to lithium or valproate). LUM simultaneously modulates serotonin, dopamine, and glutamate neurotransmission. The foregoing pleiotropic mechanism of action is predictive of therapeutic benefits across multiple domains of psychopathology in SCZ (i.e., positive, negative, cognitive, and prosocial symptoms). Herein, the overarching aim is to synthesize the extant literature reporting on the efficacy, safety, and tolerability of LUM in adults with SCZ. RECENT FINDINGS: Four clinical studies (i.e., three RCTs and one open-label trial) were included in this synthesis. Overall, LUM significantly reduced the severity of SCZ compared with placebo. The open label study provided the real-world effectiveness of shifting stable patients with SCZ to LUM from other atypical antipsychotics. With respect to safety and tolerability profile, LUM demonstrated placebo-level rates of weight gain, metabolic shift, prolactin elevation, extrapyramidal side effects (EPS), and akathisia across short term trials (i.e., 4-6 weeks). Taken together, our results indicate that LUM significantly improves symptoms severity in adults with SCZ. LUM also exhibits a favorable tolerability and safety profile with placebo level rates of weight gain, metabolic disruption, akathisia, extrapyramidal side effects (excluding akathisia), and prolactin elevation. Lumateperone should be conceptualized as a first-line treatment strategy for adults with SCZ.

Ketamine is a promising therapeutic option in treatment-resistant depression (TRD). The acute efficacy of ketamine in TRD has been demonstrated in replicated randomised-controlled trials (RCTs), but the generalizability of RCT data to real-world practice is limited. To this end, we conducted a systematic review (Search date: 25/12/2021; 1482 records identified) and meta-analysis of studies evaluating the real-world clinical effectiveness of ketamine in TRD patients. Four overlapping syntheses (Total n = 2665 patients; k = 79 studies) and 32 meta-regressions (Total n = 2050; k = 37) were conducted. All results suggest that the mean antidepressant effect is substantial (mean ± 95% CI, % responded = 45 ± 10%; p< 0.0001, % remitted = 30 ± 5.9%; p< 0.0001, Hedges g of symptomatological improvement = 1.44 ± 0.609; p < 0.0001), but the effect varies considerably among patients. The more treatment-resistant cases were found to remit less often (p < 0.01), but no such effect on response was evident (p > 0.05). Meta-regressions also confirmed that the therapeutic effect does not significantly decline with repeated treatments (p > 0.05). These results demonstrate that even the most treatment-resistant patients may benefit from ketamine, and that mid-to-long term treatment is effective in many patients.

INTRODUCTION: The overarching aim of this review is to synthesize the efficacy, tolerability, and weight-mitigation effects of the olanzapine/samidorphan (OLZ/SAM) combination treatment in adults with schizophrenia and bipolar disorder-I. METHODS: A systematic search of PubMed, Web of Science, Embase, and The Cochrane Library was conducted on August 15th, 2021. Studies were included if they investigated the use of OLZ/SAM treatment in patients with schizophrenia or bipolar disorder-I, and reported the clinical outcomes: efficacy, change in weight or waist circumference, tolerability, pharmacokinetics, or change in metabolic parameters. A narrative synthesis was undertaken of the data. RESULTS: Eight studies met the inclusion criteria. All identified studies were conducted in adults with schizophrenia. Compared to OLZ-monotherapy, OLZ/SAM was associated with decreased odds of developing clinically significant (>10%) weight gain (OR=0.50, 95% CI:0.31,0.80; p= 0.003) and increase in waist circumference (risk difference = -17.1% 95% CI:-26.3,-7.8) from baseline measurements respectively. In another study, OLZ was 2.7 times more associated with clinically significant weight gain as compared to OLZ/SAM (OR=2.73, 95% CI:1.11, 6.67; p = 0.023). The clinical efficacy of OLZ/SAM remained similar to OLZ with improved tolerability in both short- and long-term studies with no significantly altered pharmacokinetic properties of the constituent agents. CONCLUSION: OLZ/SAM-treatment is associated with mitigated weight-gain liability when compared to OLZ-monotherapy in adults with schizophrenia. Additional studies are needed to ascertain patient acceptability, appropriate selection and sequencing of OLZ/SAM in the treatment algorithms for adults with schizophrenia (and BD-I), as well as to determine cost-effectiveness and long-term metabolic effects.

BACKGROUND: Benzodiazepine (BZD) prescription rates have increased over the past decade in the United States. Available literature indicates that sociodemographic factors may influence diagnostic patterns and/or prescription behaviour. Herein, the aim of this study is to determine whether the gender of the prescriber and/or patient influences BZD prescription. METHODS: Cross-sectional study using data from the Florida Medicaid Managed Medical Assistance Program from January 1, 2018 to December 31, 2018. Eligible recipients ages 18 to 64, inclusive, enrolled in the Florida Medicaid plan for at least 1 day, and were dually eligible. Recipients either had a serious mental illness (SMI), or non-SMI and anxiety. RESULTS: Total 125 463 cases were identified (i.e., received BZD or non-BZD prescription). Main effect of patient and prescriber gender was significant F(1, 125 459) = 0.105, P = 0 .745, partial η2 < 0.001. Relative risk (RR) of male prescribers prescribing a BZD compared to female prescribers was 1.540, 95% confidence intervals (CI) [1.513, 1.567], whereas the RR of male patients being prescribed a BZD compared to female patients was 1.16, 95% CI [1.14, 1.18]. Main effects of patient and prescriber gender were statistically significant F(1, 125 459) = 188.232, P < 0.001, partial η2 = 0.001 and F(1, 125 459) = 349.704, P < 0.001, partial η2 = 0.013, respectively. CONCLUSIONS: Male prescribers are more likely to prescribe BZDs, and male patients are more likely to receive BZDs. Further studies are required to characterize factors that influence this gender-by-gender interaction.

Ketamine may exert pro-cognitive effects on select measures of cognition in adults with mood disorders. We evaluated the effectiveness of intravenous (IV) ketamine on cognition in 68 adult outpatients with treatment-resistant depression (TRD) at the Canadian Rapid Treatment Center of Excellence between July 3, 2018 and April 16, 2020 (NCT04209296). Eligibility criteria for the present retrospective study included: primary diagnosis of major depressive or bipolar disorder; currently depressed; and insufficient response to two or more prior treatments. Participants received four infusions of ketamine hydrochloride (0.5-0.75 mg/kg) over 1-2 weeks. We assessed objective and subjective measures of cognition before and after two infusions, i.e., Digit Symbol Substitution Test (DSST), Trail Making Test-B (TMT-B), Patient Deficits Questionnaire, 5-item (PDQ-5-D). Ketamine significantly improved DSST (effect size [ES]=0.60), TMT-B (ES=0.84), as well as PDQ-5-D scores (ES=0.63), indicative of a moderate-to-large effect size. Improvements in DSST and PDQ-5-D with ketamine were mediated by reductions in depressive symptoms, whereas improvements in TMT-B were independent of changes in depressive symptoms. Our results support the independent, rapid-onset, pro-cognitive effects with IV ketamine in adults with TRD. Larger, randomized, controlled trials with ketamine wherein cognition is the primary outcome measure in mood and non-mood disorder samples are warranted.

BACKGROUND: The COVID-19 pandemic represents a public health, economic and mental health crisis. We hypothesized that timely government implementation of stringent measures to reduce viral transmission would benefit mental health, as evidenced by reduced rates of depressive symptoms (i.e., Patient Health Questionnaire [PHQ]-9≥10, PHQ-2≥3). METHODS: The systematic review herein (PROSPERO CRD42020200647) evaluated to what extent differences in government-imposed stringency and timeliness of response to COVID-19 moderate the prevalence of depressive symptoms across 33 countries (k=114, N=640,037). We included data from six lower-middle-income countries, nine upper-middle-income countries, and 18 higher-income countries. Government-imposed stringency and timeliness in response were operationalized using the Oxford COVID-19 Government Response ("Stringency") Index. RESULTS: The overall proportion of study participants with clinically significant depressive symptoms was 21.39% (95% CI 19.37-23.47). The prevalence of clinically significant depressive symptoms was significantly lower in countries wherein governments implemented stringent policies promptly. The moderating effect of government response remained significant after including the national frequency of COVID cases at the time of study commencement, Healthcare Access and Quality index, and the inclusion of COVID patients in the study. LIMITATIONS: Factors that may have confounded our results include, for example, differences in lockdown duration, lack of study participant and outcome assessor blinding, and retrospective assessment of depressive symptom severity. CONCLUSIONS: Governments that enacted stringent measures to contain the spread of COVID-19 benefited not only the physical, but also the mental health of their population.

The efficacy of ketamine in reducing suicidal ideation (SI) has been previously reported. We aimed to evaluate acute anti-SI effects of single-dose ketamine in different formulations/routes of administration by pooling results from randomized controlled trials (RCTs). A systematic search was conducted on Cochrane, Embase, Medline, and PubMed from inception to July 1st, 2020. Studies were selected based on pre-determined eligibility criteria. Effect sizes of different formulations/routes at various time points were computed using random-effects models. With data from nine eligible RCTs (n = 197), the pooled effect size for anti-SI effects at the 24-h time point was 1.035 (N = 6, CI: 0.793 to 1.277, p < 0.001) for intravenous (IV) racemic ketamine and 1.309 (N = 1, CI: 0.857 to 1.761, p < 0.001) for intranasal (IN) esketamine. An additional five RCTs were available for qualitative analysis. RCTs were identified for oral/sublingual ketamine for depression, however, none of these trials reported anti-SI effects preventing quantitative analysis for these routes of delivery. No RCTs for intramuscular (IM) ketamine were identified. The findings suggest that single-dose IV ketamine/IN esketamine is associated with robust reductions in suicidal thoughts at 2-h, 4-h, and 24-h post-intervention. In addition, future studies on IM/oral/sublingual ketamine and comparative studies are warranted to evaluate the anti-SI efficacy of distinct formulations and routes of administration.

Antidepressant medications are the first-line treatment option for moderate to severe major depressive disorder. However, most antidepressants have numerous documented adverse events, including cardiometabolic effects and weight gain, which are major public health concerns. Antidepressant agents provide varying risk of associated weight gain, including significant within-class differences. Some agents, such as mirtazapine, show significant levels of weight gain, while others, such as bupropion, demonstrate weight-loss effects. Current findings suggest the role of histamine and serotonin off-target appetite-promoting pathways in adverse weight-gain effects. Therefore, controlling for undesired weight effects is an important consideration for the selection of antidepressants.

INTRODUCTION: Mental illness has a chronic course of illness with a number of clinical manifestations. Affected individuals experience significant functional, emotional, cognitive, and/or behavioral impairments. The growing prevalence of mental illness has been associated with significant social and economic costs. Indeed, the economic burden of mental illness is estimated to exceed $1.8 trillion USD over the next 30 years. A significant number of individuals affected by mental illness fail to respond to first-line treatment options. Therefore, there remains an unmet need for rapidly attenuating therapeutic options for mental health disorders with minimal social and economic burden. AREAS COVERED: The paucity of novel treatment options warrants a renewed investigation of psychedelic-based psychotherapy. Herein, the authors will evaluate the therapeutic potential of traditional psychedelics, psilocybin, and MDMA, in the treatment of mental illness with a narrative review of available literature. EXPERT OPINION: Psychedelics, such as psilocybin and MDMA, offer an alternative avenue of therapy for many mental health disorders. Available evidence indicates that psychedelics may offer a single-dose, rapid effect model that have robust effects with treatment-resistant mental disorders and a unique advantage as a possible monotherapy for mental illness. Novel clinical trials that evaluate the safety, tolerability, and efficacy in clinically representative populations are warranted.

BACKGROUND: As a major virus outbreak in the 21st century, the Coronavirus disease 2019 (COVID-19) pandemic has led to unprecedented hazards to mental health globally. While psychological support is being provided to patients and healthcare workers, the general public's mental health requires significant attention as well. This systematic review aims to synthesize extant literature that reports on the effects of COVID-19 on psychological outcomes of the general population and its associated risk factors. METHODS: A systematic search was conducted on PubMed, Embase, Medline, Web of Science, and Scopus from inception to 17 May 2020 following the PRISMA guidelines. A manual search on Google Scholar was performed to identify additional relevant studies. Articles were selected based on the predetermined eligibility criteria. RESULTS: Relatively high rates of symptoms of anxiety (6.33% to 50.9%), depression (14.6% to 48.3%), post-traumatic stress disorder (7% to 53.8%), psychological distress (34.43% to 38%), and stress (8.1% to 81.9%) are reported in the general population during the COVID-19 pandemic in China, Spain, Italy, Iran, the US, Turkey, Nepal, and Denmark. Risk factors associated with distress measures include female gender, younger age group (≤40 years), presence of chronic/psychiatric illnesses, unemployment, student status, and frequent exposure to social media/news concerning COVID-19. LIMITATIONS: A significant degree of heterogeneity was noted across studies. CONCLUSIONS: The COVID-19 pandemic is associated with highly significant levels of psychological distress that, in many cases, would meet the threshold for clinical relevance. Mitigating the hazardous effects of COVID-19 on mental health is an international public health priority.

BACKGROUND: Replicated evidence has documented elevated levels of pro-inflammatory cytokines in populations with major depressive disorder (MDD). However, childhood trauma, a risk factor for MDD, has been separately shown to also impact inflammatory systems; its potential moderating effect on inflammation in MDD has been less frequently investigated. METHODS: We systematically searched the PubMed, Google Scholar, Scopus, Web of Science, and PsycINFO databases between database inception to June 19th, 2019 using the search string: (Childhood trauma or Adverse childhood experiences or childhood abuse or childhood rape or physical abuse or emotional abuse) AND (Inflammation or inflammatory cytokines or interleukin-6 or tumor necrosis factor-alpha or c-reactive protein) AND (Major Depressive Disorder or Depression). RESULTS: We identified nine articles that evaluated inflammatory biomarkers in MDD populations with adverse childhood experiences (ACE). Eight articles evaluated IL-6, three articles evaluated CRP, and five articles evaluated TNF-α. The strongest effects were observed for IL-6; six studies reported significantly elevated levels of IL-6 in MDD and ACE patients compared to healthy controls and/or MDD-only populations. Meanwhile, only three studies found TNF-α to be significantly elevated in the MDD and ACE cohort. In contrast, MDD-ACE populations did not exhibit significantly elevated CRP. LIMITATIONS: The methodological heterogeneity amongst studies was very high. CONCLUSION: The current review suggests that MDD and ACE subpopulations present elevated levels of IL-6 compared to MDD-only and healthy control populations. Therefore, research should consider whether elevated inflammation in MDD is just an epiphenomenon of previous ACE and whether MDD-ACE subgroups are more likely to respond to immune-inflammatory targeted intervention.
