Guidelines for the pharmacological acute treatment of major depression: conflicts with current evidence as demonstrated with the German S3-guidelines

Multiomics and blood-based biomarkers of electroconvulsive therapy in severe and treatment-resistant depression: study protocol of the DetECT study

Electroconvulsive therapy (ECT) is commonly used to treat treatment-resistant depression (TRD). However, our knowledge of the ECT-induced molecular mechanisms causing clinical improvement is limited. To address this issue, we developed the single-center, prospective observational DetECT study ("Multimodal Biomarkers of ECT in TRD"; registered 18/07/2022, www.clinicalTrials.gov , NCT05463562). Its objective is to identify molecular, psychological, socioeconomic, and clinical biomarkers of ECT response in TRD. We aim to recruit n = 134 patients in 3 years. Over the course of 12 biweekly ECT sessions (± 7 weeks), participant blood is collected before and 1 h after the first and seventh ECT and within 1 week after the twelfth session. In pilot subjects (first n = 10), additional blood draws are performed 3 and 6 h after the first ECT session to determine the optimal post-ECT blood draw interval. In blood samples, multiomic analyses are performed focusing on genotyping, epigenetics, RNA sequencing, neuron-derived exosomes, purines, and immunometabolics. To determine clinical response and side effects, participants are asked weekly to complete four standardized self-rating questionnaires on depressive and somatic symptoms. Additionally, clinician ratings are obtained three times (weeks 1, 4, and 7) within structured clinical interviews. Medical and sociodemographic data are extracted from patient records. The multimodal data collected are used to perform the conventional statistics as well as mixed linear modeling to identify clusters that link biobehavioural measures to ECT response. The DetECT study can provide important insight into the complex mechanisms of ECT in TRD and a step toward biologically informed and data-driven-based ECT biomarkers.

Folate and Its Significance in Depressive Disorders and Suicidality: A Comprehensive Narrative Review

Depressive disorders pose significant challenges to global public health, necessitating effective prevention and management strategies. Notably, the occurrence of suicide frequently coincides with depressive episodes. Suicide is as a paramount global health concern that demands efficacious preventive strategies. Current psychiatric approaches heavily rely on pharmacological interventions but have had limited success in addressing the global burden of mental health issues. Suboptimal nutrition, with its impact on the neuroendocrine system, has been implicated in the underlying pathology of depressive disorders. Folate, a group of water-soluble compounds, plays a crucial role in various central nervous system functions. Depressed individuals often exhibit low levels of serum and red blood cell folate. Multiple studies and systematic reviews have investigated the efficacy of folic acid and its derivative, L-methylfolate, which can cross the blood-brain barrier, as stand-alone or adjunct therapies for depression. Although findings have been mixed, the available evidence generally supports the use of these compounds in depressed individuals. Recent studies have established links between the one-carbon cycle, folate-homocysteine balance, immune system function, glutamate excitation via NMDA (N-methyl-D-aspartate) receptors, and gut microbiome eubiosis in mood regulation. These findings provide insights into the complex neurobiological mechanisms underlying the effects of folate and related compounds in depression. Through a comprehensive review of the existing literature, this study aims to advance our understanding of the therapeutic potential of folic acid and related compounds in depression treatment. It also seeks to explore their role in addressing suicidal tendencies and shed light on the neurobiological mechanisms involved, leveraging the latest discoveries in depression research.

Pharmacological Management of Borderline Personality Disorder and Common Comorbidities

Comorbidity between borderline personality disorder (BPD) and other mental disorders is common. Although no specific pharmacological treatments have been approved for the treatment of BPD, many drugs, including antidepressants such as selective serotonin reuptake inhibitors (SSRIs), mood stabilizers, second-generation antipsychotics, and even benzodiazepines, are routinely prescribed off label. Nonetheless, recommendations for off-label drugs in these patients are highly varied, with a notable lack of agreement among clinical guidelines. The most common reason for pharmacological treatment and polypharmacy in these patients is comorbidity with other psychiatric disorders. In this context, we reviewed major clinical guidelines and the available data on pharmacotherapy in patients with BPD to develop practical recommendations to facilitate decision-making in routine clinical practice, thus helping clinicians to select the optimal therapeutic approach in patients with BPD who have comorbid disorders. This review confirmed that no clear recommendations for the pharmacological treatment are available in clinical guidelines. Therefore, based on the available evidence, we have developed a series of recommendations for pharmacotherapy in patients with BPD who present the four most common comorbidities (affective, anxiety, eating, and drug use disorders). Here, we discuss the recommended treatment approach for each of these comorbid disorders. The prescription of medications should be considered only as an adjunct to BPD-specific psychotherapy. Polypharmacy and the use of unsafe drugs (i.e., with a risk of overdose) should be avoided. Our review highlights the need for more research to provide more definitive guidance and to develop treatment algorithms.

International clinical practice guidelines for gender minority/trans people: systematic review and quality assessment

OBJECTIVES

To identify and critically appraise published clinical practice guidelines (CPGs) regarding healthcare of gender minority/trans people.

DESIGN

Systematic review and quality appraisal using AGREE II (Appraisal of Guidelines for Research and Evaluation tool), including stakeholder domain prioritisation.

SETTING

Six databases and six CPG websites were searched, and international key opinion leaders approached.

PARTICIPANTS

CPGs relating to adults and/or children who are gender minority/trans with no exclusions due to comorbidities, except differences in sex development.

INTERVENTION

Any health-related intervention connected to the care of gender minority/trans people.

MAIN OUTCOME MEASURES

Number and quality of international CPGs addressing the health of gender minority/trans people, information on estimated changes in mortality or quality of life (QoL), consistency of recommended interventions across CPGs, and appraisal of key messages for patients.

RESULTS

Twelve international CPGs address gender minority/trans people's healthcare as complete (n=5), partial (n=4) or marginal (n=3) focus of guidance. The quality scores have a wide range and heterogeneity whichever AGREE II domain is prioritised. Five higher-quality CPGs focus on HIV and other blood-borne infections (overall assessment scores 69%-94%). Six lower-quality CPGs concern transition-specific interventions (overall assessment scores 11%-56%). None deal with primary care, mental health or longer-term medical issues. Sparse information on estimated changes in mortality and QoL is conflicting. Consistency between CPGs could not be examined due to unclear recommendations within the World Professional Association for Transgender Health Standards of Care Version 7 and a lack of overlap between other CPGs. None provide key messages for patients.

CONCLUSIONS

A paucity of high-quality guidance for gender minority/trans people exists, largely limited to HIV and transition, but not wider aspects of healthcare, mortality or QoL. Reference to AGREE II, use of systematic reviews, independent external review, stakeholder participation and patient facing material might improve future CPG quality.

Acceptance and Commitment Therapy for Major Depressive Disorder: Insights into a New Generation of Face-to-Face Treatment and Digital Self-Help Approaches

Major depressive disorder (MDD) represents a key contributor to the global burden of mental illness given its relatively high lifetime prevalence, frequent comorbidity, and disability rates. Evidence-based treatment options for depression include pharmacotherapy and psychotherapy, such as cognitive behavioral therapy (CBT). Beyond traditional CBT, over 15 years ago, Hayes proclaimed a new generation of contextualistic and process-orientated so-called third wave of CBT interventions, including acceptance and commitment therapy (ACT). Using mindfulness and acceptance as well as commitment and behavior change processes, the transdiagnostic ACT approach aims to increase psychological flexibility as universal mechanism of behavior change and to build a value-driven orientation in life. ACT for MDD can be provided as either stand-alone individual, group, or self-help formats (e.g., apps) or combined with other approaches like behavioral activation. To date, a steadily growing empirical support from outcome and process research suggests the efficacy of ACT, which appears to work specifically through the six proposed core processes involved in psychological flexibility, such as defusion. In view of an ongoing interest of clinicians in "third-wave" CBTs and the important role of clients' preferences in providing therapy choices that work, the purpose of this chapter is to give a brief overview on the application of ACT in the treatment of MDD in adults.

Depression and anxiety in relation to cancer incidence and mortality: a systematic review and meta-analysis of cohort studies

The link between depression and anxiety status and cancer outcomes has been well-documented but remains unclear. We comprehensively quantified the association between depression and anxiety defined by symptom scales or clinical diagnosis and the risk of cancer incidence, cancer-specific mortality, and all-cause mortality in cancer patients. Pooled estimates of the relative risks (RRs) for cancer incidence and mortality were performed in a meta-analysis by random effects or fixed effects models as appropriate. Associations were tested in subgroups stratified by different study and participant characteristics. Fifty-one eligible cohort studies involving 2,611,907 participants with a mean follow-up period of 10.3 years were identified. Overall, depression and anxiety were associated with a significantly increased risk of cancer incidence (adjusted RR: 1.13, 95% CI: 1.06-1.19), cancer-specific mortality (1.21, 1.16-1.26), and all-cause mortality in cancer patients (1.24, 1.13-1.35). The estimated absolute risk increases (ARIs) associated with depression and anxiety were 34.3 events/100,000 person years (15.8-50.2) for cancer incidence and 28.2 events/100,000 person years (21.5-34.9) for cancer-specific mortality. Subgroup analyses demonstrated that clinically diagnosed depression and anxiety were related to higher cancer incidence, poorer cancer survival, and higher cancer-specific mortality. Psychological distress (symptoms of depression and anxiety) was related to higher cancer-specific mortality and poorer cancer survival but not to increased cancer incidence. Site-specific analyses indicated that overall, depression and anxiety were associated with an increased incidence risks for cancers of the lung, oral cavity, prostate and skin, a higher cancer-specific mortality risk for cancers of the lung, bladder, breast, colorectum, hematopoietic system, kidney and prostate, and an increased all-cause mortality risk in lung cancer patients. These analyses suggest that depression and anxiety may have an etiologic role and prognostic impact on cancer, although there is potential reverse causality; Furthermore, there was substantial heterogeneity among the included studies, and the results should be interpreted with caution. Early detection and effective intervention of depression and anxiety in cancer patients and the general population have public health and clinical importance.
