OBJECTIVE: The study objective was to generate a prediction model for treatment-resistant depression (TRD) using machine learning featuring a large set of 47 clinical and sociodemographic predictors of treatment outcome. METHOD: 552 Patients diagnosed with major depressive disorder (MDD) according to DSM-IV criteria were enrolled between 2011 and 2016. TRD was defined as failure to reach response to antidepressant treatment, characterized by a Montgomery-Asberg Depression Rating Scale (MADRS) score below 22 after at least 2 antidepressant trials of adequate length and dosage were administered...

Desvenlafaxine exposure in Korean and US populations was compared using population pharmacokinetic (PK) analysis. Data from a single- and multiple-dose study of desvenlafaxine (50, 100, and 200 mg) in 30 healthy Korean subjects were added to a population PK model previously developed using sparse PK samples from patients with major depressive disorder, including 140 Korean patients, combined with rich PK data from healthy volunteers. The structural PK model was an open 1-compartment linear disposition model with parallel first-order and 0-order inputs...

BACKGROUND: Major depressive disorder (MDD) is characterized by high relapse/recurrence rates. Predicting individual patients' relapse/recurrence risk has proven hard, possibly due to course heterogeneity among patients. This study aimed to (1) identify homogeneous data-driven subgroups with different patterns of relapse/recurrence and (2) identify associated predictors. METHODS: For a year, we collected weekly depressive symptom ratings in 213 primary care MDD patients...

In 2015, a large number of refugees arrived in Germany, mostly driven to emigrate by devastating circumstances in their countries of origin. Arriving refugees are distributed to reception centers within the German federal states, frequently facing marginal conditions in terms of overcrowding or waiting time of several months until their application for asylum is processed. Most of these refugees underwent numerous traumatizing experiences-both in their country of origin and while fleeing from their country of origin...

Background: Major depressive disorder is a leading cause of disability worldwide; however, little is known about pathological mechanisms involved in its development. Research in adolescent depression has focused on reward sensitivity and striatal mechanisms implementing it. The contribution of loss sensitivity to future depression, as well as the orbitofrontal cortex (OFC) mechanisms critical for processing losses and rewards, remain unexplored. Furthermore, it is unclear whether OFC functioning interacts with familial history in predicting future depression...

Increasing clinical evidence suggests that regular physical exercise can prevent or reduce the incidence of stress-related psychiatric disorders including depressive symptoms. Antidepressant effect of regular exercise may be implicated in monoaminergic transmission including serotonergic transmission, activation of the hypothalamic-pituitary-adrenal (HPA) axis, and hippocampal neurogenesis, but few general concepts regarding the optimal exercise regimen for stimulating neural mechanisms involved in antidepressant properties have been developed...

Bipolar disorder (BPD) and major depressive disorder (MDD) are primary major mood disorders. Recent studies suggest that they share certain psychopathological features and common risk genes, but unraveling the full genetic architecture underlying the risk of major mood disorders remains an important scientific task. The public genome-wide association study (GWAS) data sets offer the opportunity to examine this topic by utilizing large amounts of combined genetic data, which should ultimately allow a better understanding of the onset and development of these illnesses...

OBJECTIVE: Cognitive complaints are considered early indicators of incipient Alzheimer's disease (AD) but are very common in geriatric patients, especially in patients with major depressive disorder (MDD). The clinical assessment of cognitive complaints is still poorly operationalized. Recent qualitative research suggests that certain phenomenologic complaint themes may have some specificity for prodromal AD. The aim of the study was to replicate and explore their occurrence in a clinical setting...

Repetitive transcranial magnetic stimulation (rTMS) has demonstrated efficacy in major depressive disorder (MDD), although clinical outcome is variable. Change in the resting-state quantitative electroencephalogram (qEEG), particularly in theta cordance early in the course of treatment, has been linked to antidepressant medication outcomes but has not been examined extensively in clinical rTMS. This study examined change in theta cordance over the first week of clinical rTMS and sought to identify a biomarker that would predict outcome at the end of 6 weeks of treatment...

The comparative effects of cortisol and 11-deoxycorticosterone (DOC), two major corticosteroids in fish, have yet received little attention in teleosts. We evaluated the proteomic and immune responses of Eurasian perch to chronic corticosteroid treatments. We implanted immature perch with cortisol (80mg/kg) or DOC (4mg/kg) and measured the proportions of blood leucocytes, immune indices in the plasma, spleen and liver (complement and lysozyme activity, total immunoglobulin and immune gene expression in the tissues) and differential proteome expression (corticosteroid versus control) in the liver and the spleen on days 2, 4 and 14 post-treatment...

BACKGROUND: In clinical trials, statistical analysis often requires certain assumptions about missing data for a valid statistical inference. If the dropout rate is high, a wrong assumption about the missing data may compromise the validity of statistical inferences. PURPOSE: To mitigate the high dropout rates commonly observed in psychiatry clinical trials, we consider two design approaches for short-term controlled trials submitted in support of marketing applications for drug products for the major depressive disorder (MDD) indication: (1) shortening the trial duration and (2) treating time to treatment discontinuation as an alternative primary efficacy endpoint...

Increasing evidence has implicated astrocyte pathology in the etiopathology of major depressive disorder (MDD). In particular, dysfunction of gap junctions in astrocytes is a potential target for MDD treatment. However, the mechanism underlying stress-induced dysfunction of gap junctions is still unknown. We therefore studied the mechanism of stress-induced dysfunction of gap junctions in prefrontal cortical and hippocampal astrocytes. Corticosterone (CORT) was used to induce stress conditions; CORT damaged the function of gap junctions, which resulted from less distribution of connexin43 (Cx43) on membranes and the enhanced phosphorylation of Cx43 at S368...

BACKGROUND: Mental imagery has a more powerful impact on our emotions than thinking in words about the same material. Treating intrusive images with imagery rescripting (IR) has been reported for various disorders, including post-traumatic stress disorder, social anxiety disorder, and bipolar disorder. There has been less research about IR as a major depressive disorder (MDD). AIMS: We examined whether IR without focusing on early traumatic memories is effective in MDD...

Considering the involvement of the opioid system in major depressive disorder (MDD), mainly concerning refractory MDD, and the evidence that ascorbic acid may exert a beneficial effect for the treatment of this disorder, this study investigated the involvement of the opioid system in the antidepressant-like effect of ascorbic acid in the tail suspension test (TST). Treatment of Swiss mice with the non-selective opioid receptor antagonist naloxone (1 mg/kg, i.p.) prevented the reduced immobility time caused by ascorbic acid (1 mg/kg, p...
