Background: Although there is clear evidence that therapeutic drug monitoring (TDM) has beneficial effects for patients treated with tricyclic antidepressants, it is generally not recommended for second-generation antidepressants (SGA). However, it has been suggested that methodological shortcomings might influence the results in TDM studies with SGA.

Aim: A qualitative assessment of randomized controlled trials (RCTs) that specifically investigated drug concentration-effect relationships of SGA in patients with major depressive disorder (MDD) to analyze the potential benefit of TDM during treatment with these agents.

Article Synopsis
  • There is evidence suggesting that the HPA axis may not function properly in people with chronic tinnitus, but previous studies have shown mixed results, possibly due to varied clinical factors.
  • This study compares salivary cortisol levels in tinnitus sufferers and healthy controls to investigate the effects of childhood trauma and anxiety on HPA-axis functioning.
  • The results indicate that individuals with tinnitus who experienced childhood trauma have lower cortisol awakening responses, suggesting trauma impacts HPA function, while anxiety did not significantly affect any outcomes.

Article Synopsis
  • Depression is typically viewed as a disease caused by a common factor, but this study takes a network approach, focusing on how individual symptoms influence each other and their dynamics over time.
  • Using the Symptom Questionnaire-48 (SQ-48), researchers examined patient data with dynamic time warp analyses, discovering significant interconnections between various symptoms and how certain symptoms led to changes in others.
  • The study identified five symptoms ('hopeless', 'restless', 'down/depressed', 'feeling tense', and 'no enjoyment') that could be targeted for more effective, personalized treatments, though the focus on severely depressed inpatients limits the generalizability of the findings.

Background: While theta burst stimulation (TBS) shows promise in Major Depressive Disorder (MDD), its effectiveness in bipolar depression (BD-D) remains uncertain. Optimizing treatment parameters is crucial in the pursuit of rapid symptom relief. Moreover, aligning with personalized treatment strategies and increased interest in immunopsychiatry, biomarker-based stratification of patients most likely to benefit from TBS might improve remission rates.

Background: The Cultural Formulation Interview (CFI) is designed to improve understanding of patients' mental health care needs. The lack of empirical evidence on the impact and effectiveness of CFI use in clarifying people's perspectives, experiences, context, and identity, and in preventing cultural misunderstandings between migrant patients and clinicians, inspired this study. The objective is to examine the effect of the CFI on the strength of therapeutic working alliances, and the potential mediating or moderating role of perceived empathy.

Psychomotor slowing has consistently been observed in schizophrenia, however research on motor learning in schizophrenia is limited. Additionally, motor learning in schizophrenia has never been compared with the waning of motor learning abilities in the elderly. Therefore, in an extensive study, 30 individuals with schizophrenia, 30 healthy age-matched controls and 30 elderly participants were compared on sensorimotor learning tasks including sequence learning and adaptation (both explicit and implicit), as well as tracking and aiming.

Background: Electroconvulsive therapy (ECT) remains the one of the most effective of biological antidepressant interventions. However, the exact neurobiological mechanisms underlying the efficacy of ECT remain unclear. A gap in the literature is the lack of multimodal research that attempts to integrate findings at different biological levels of analysis METHODS: We searched the PubMed database for relevant studies.

Objective: Tinnitus can be regarded as a chronic stressor, leading to dysregulation of the hypothalamic-pituitary-adrenal (HPA) axis. There is important comorbidity with anxiety, particularly panic, potentially associated with differences in HPA axis functioning and methylation patterns of HPA axis-related genes. This study examines DNA methylation of the glucocorticoid receptor gene ( NR3C1 ) exon 1F in adults with chronic subjective tinnitus and the possible differential effect of panic.

Background: Despite a high prevalence of mental disorders among asylum seekers, many barriers to mental healthcare exist. Cultural and contextual factors strongly influence the experience and expression of psychological distress, putting asylum seekers at greater risk of misdiagnosis and inappropriate treatment. The Cultural Formulation Interview (CFI) is a useful tool to map out cultural and contextual factors of mental disorders; however, to the best of our knowledge, it has not yet been investigated in asylum seekers specifically.

ECT is proposed to exert a therapeutic effect on WM microstructure, but the limited power of previous studies made it difficult to highlight consistent patterns of change in diffusion metrics. We initiated a multicenter analysis and sought to address whether changes in WM microstructure occur following ECT. Diffusion tensor imaging (DTI) data (n = 58) from 4 different sites were harmonized before pooling them by using ComBat, a batch-effect correction tool that removes inter-site technical variability, preserves inter-site biological variability, and maximizes statistical power.

It remains unclear whether psychotic depression (PD) compared to non-psychotic depression (non-PD) among older adults is associated with poorer cognitive performance. For inpatients (60+) with a major depressive episode, cognitive performance in PD and non-PD (categorical) were compared as well as the relationship between symptom severity for depression and psychosis (dimensional) and cognition. Of 90 participants (on average 72.

Cognitive function during an ECT care pathway is mainly investigated at the group level by analyzing mean cognitive test scores over time. However, there are important inter-individual differences, with some patients experiencing residual invalidating cognitive deficits. This study provides a nuanced examination of cognitive functioning during and after ECT by combining three approaches for data analysis.

Introduction: Chronic low-grade inflammation is suggested to play a pathophysiological role in bipolar disorder (BD) and its related cognitive dysfunctions. Although kynurenine (KYN) pathway metabolites are key inflammatory mediators, studies investigating the association between KYN metabolism and cognition in BD are scarce. We aimed to explore the relationship between KYN metabolism and cognitive functioning across different mood states in BD.

Introduction: The neurobiological mechanisms underlying the acute cognitive effects of electroconvulsive therapy (ECT) remain poorly understood. Prior research has shown that proinflammatory cytokines such as IL-6, TNF-α, IL1-β, and IL-10 may interfere with cognitive functioning. Interestingly, immunomodulation is one of the proposed modes of action of ECT.
