OBJECTIVE: To characterize self-poisoning suicide deaths in BD compared to other suicide decedents. METHODS: Extracted coroner data from all suicide deaths (n = 3319) in Toronto, Canada from 1998 to 2012. Analyses of demographics, clinical history, recent stressors, and suicide details were conducted in 5 subgroups of suicide decedents: BD self-poisoning, BD other methods, non-BD self-poisoning, non-BD other methods, and unipolar depression self-poisoning. Toxicology results for lethal and present substances were also compared between BD and non-BD self-poisoning subgroups as well as between BD and unipolar depression self-poisoning subgroups...

Treatment of unipolar depression with currently available antidepressants is still unsatisfactory. Augmentation with lithium or second generation antipsychotics is an established practice in non-responders to antidepressant monotherapy, but is also associated with a substantial non-response rate and with non-tolerance. Based on a systematic review of the literature, including meta-analyses, randomized controlled trials (RCTs), non-randomized comparative studies and case studies, off-label augmentation agents (administered in addition to an antidepressant, without FDA approval for treatment of MDD) were identified and evaluated regarding their efficacy using levels of evidence...

OBJECTIVES: The high percentage of failed clinical trials for anti-depressant medications, especially in elderly populations, obscures the fact that some patients may benefit greatly from treatment. Early detection of patients who may benefit most from antidepressant medication may improve treatment decisions. We examined whether depressed patients in a large clinical trial exhibit distinct trajectories of early symptom change that predict differential response to medication or placebo...

OBJECTIVE: This study aimed to explore effects of adjunctive N-acetylcysteine (NAC) treatment on inflammatory and neurogenesis markers in unipolar depression. METHODS: We embarked on a 12-week clinical trial of NAC (2000 mg/day compared with placebo) as an adjunctive treatment for unipolar depression. A follow-up visit was conducted 4 weeks following the completion of treatment. We collected serum samples at baseline and the end of the treatment phase (week 12) to determine changes in interleukin-6 (IL6), C-reactive protein (CRP) and brain-derived neurotrophic factor (BDNF) following NAC treatment...

The Lundby Study is a prospective mental health survey in a community population (N = 3563), in which data were collected in 4 waves of field-work between 1947 and 1997. We investigated gender differences during the follow-up in overall first incidence rates, ages of onset, and incidence by age of onset patterns, in different subtypes of depression. The overall incidence rate in females was higher than males for most subtypes of depression. However, for depression with melancholic and/or psychotic features, the overall first incidence rate did not differ significantly between the genders...

In clinical practice, there is a need for a more individualized selection of antidepressants and adequate dosage. The investigation of pharmacokinetically relevant genes is a promising approach to assist this selection. In the past 2 years, two commercially available tests have been subject of advertisement, a test from Stada, which analyses variants of the cytochrome P450 isoenzymes CYP2D6 and CYP2C19 and a test from HMNC Brain Health, which analyses variants of the ABCB1 gene. The costs for both kits are not covered by the statutory health insurance and it is therefore proposed that the patients are invoiced directly in the form of individual healthcare payment...

BACKGROUND: Numerous studies have reported reduced peripheral brain-derived neurotrophic factor (BDNF) in major depression (MD). However, most of these studies used multidimensional depression rating scales, and failed to identify a relationship between BDNF levels and depression severity. Unidimensional scales are a more valid measure of syndrome severity. In these scales, items are ordered in increasing severity, so that as scores increase, syndrome severity increases; thus, each item adds unique information, and items can be totaled to a meaningful sum...

BACKGROUND: Early adversity is a known risk factor for unipolar depression. We examined the impact of 9 types of early adversity on risk for moderate to severe unipolar depression in adolescence or adulthood, and evaluated whether these effects were moderated by gender and adversity timing. METHODS: We conducted a prospective, population-based cohort study using Danish national registers. The sample included all individuals born in Denmark between 1980 and 1998 (N=978,647)...

Background: Deep brain stimulation (DBS) is a neurosurgical intervention with demonstrated effectiveness for treatment resistant depression (TRD), but longitudinal studies on the stability of cognitive parameters following treatment are limited. The objectives of this study are to (i) identify baseline cognitive predictors of treatment response to subcallosal cingulate gyrus (SCG) DBS for unipolar TRD and (ii) compare neurocognitive performance prior to and 12 months after DBS implantation. Methods: Twenty unipolar TRD patients received SCG DBS for 12 months...

Few studies have examined relationships between circadian rhythms and unipolar major depressive disorder. Further, no study to date has examined circadian markers as predictors of response to depression treatment. In the present study, we examined associations between circadian timing and its alignment with sleep and depression severity in 30 adults with major depressive disorder who completed a randomized controlled trial of two weeks of time in bed (TIB) restriction administered adjunctive to fluoxetine, with a focus on sex differences...

Self-concept is used to explain emotional disturbance or other behavioural and psychological problems associated with depression. Self-referential processing generally reflects self-concept in different domains. Cortical midline structures, such as the medial prefrontal cortex (MPFC), are critical for self-referential processing both in healthy controls and depressive patients. However, the role of subregions of the MPFC in self-referential processing in depression remains uncertain. In this study, we aimed to explore the neural basis of self-referential processing in depressive patients and the activation-deactivation patterns of subregions of the MPFC...

Mixed states address the relationships between episodes and the course of an illness, presenting significant clinical challenges. Recurrent affective disorders were described thousands of years ago as dimensional disturbances of the basic elements of behavior, combining the characteristics of what we would now consider manic and depressive episodes. It was recognized from the beginning that combinations of depressive and manic features are associated with a severe illness course, including increased suicide risk...

INTRODUCTION: Early diagnosis and management of depression is important for better therapeutic outcome. Strategies for distinguishing between unipolar and bipolar depression are yet to be defined, resulting improper management. This study aims at comparing the socio-demographic and other variables between patients with unipolar and bipolar depression, along with assessment of severity of depression. MATERIALS AND METHODS: This cross sectional study was conducted in a tertiary care psychiatry hospital in North-East India...

BACKGROUND: Depressive disorders are a leading cause of the global burden of disease and are associated with high recurrent often continuing morbidity and high excess mortality by suicide and cardiovascular disease. Whilst there are established, effective and cost-effective treatments for depression, their long-term management is often neglected: there is continuing controversy over the case of need for long-term treatment including lifelong treatment and safety issues. OBJECTIVE AND METHODS: In this narrative review, we critically examine the evidence for the effectiveness and safety of lithium salts in the long-term management of unipolar depression...
