Several lines of evidence implicate serotonin in the etiology of multiple psychiatric disorders, especially mood disorders, such as major depressive disorder (MDD) and bipolar disorder (BD). Much of our current understanding of biological mechanisms underlying serotonergic alterations in mood disorders comes from animal studies. Innovation in induced pluripotent stem cell and transdifferentiation technologies for deriving neurons from adult humans has enabled the study of disease-relevant cellular phenotypes in vitro...

OBJECTIVE: To examine 5-year trajectories of psychiatrist-treated late-life major depressive disorder (MDD), and evaluate whether previous vascular pathology is associated with more severe trajectories of late-life MDD. METHODS: Data were obtained from nationally representative civil, psychiatric, hospital, and prescription registers in Denmark. The sample included 11,092 older adults (≥60 years) who received their first diagnosis of MDD in a psychiatric facility in Denmark between 2000 and 2007...

OBJECTIVE: While research on substance abuse has largely focused on people who have a single substance use disorder (SUD), many people abuse multiple substances. Studies have yet to examine the distinctive characteristics of patients diagnosed with more than 1 SUD and how those with polysubstance use disorder (PSUD) differ from those with a single SUD. METHODS: National Veterans Health Administration data from fiscal year 2012 were used to compare veterans diagnosed 1 SUD to veterans diagnosed with 2-3, and >3 SUDs on demographic characteristics, psychiatric and medical diagnoses, medical and psychiatric service utilization, and psychotropic medication fills...

MiR-21 is a microRNA implicated in cancer, development, and cardiovascular diseases and expressed in the central nervous system (CNS), especially after injury. However, the cellular expression of miR-21 in the adult CNS has not been clearly established either in mice or human subjects, while its alteration in psychiatric disorders is unknown. MiR-21 expression was characterized in reporter mice expressing β-galactosidase (LacZ) under the endogenous miR-21 promoter (miR-21/LacZ). Brain co-localization of miR-21/LacZ with specific neural markers was examined by double immunofluorescence in reporter mice, while extent of immunostaining for myelin basic protein and PDGFRα was determined in miR-21 knockout and wild-type mice...

This article describes psychiatric emergencies in pregnant women. The perinatal period is a time of psychiatric vulnerability. Up to 1 in 6 pregnant women experience major depressive disorder, and 1 in 4 pregnant women with bipolar disorder experience mood exacerbation. We discuss the management of severe mental illness in pregnancy, risk to mother and child of untreated psychiatric illness in pregnancy, risk of relapse of psychiatric disorders in pregnancy with medication discontinuation, psychopharmacologic considerations of teratogenicity and other fetal adverse effects, acute agitation in the pregnant patient, suicidality in pregnancy, and emergency considerations related to substance use disorders...

BACKGROUND: The death of a parent is a highly stressful life event for bereaved children. Several studies have shown an increased risk of mental ill-health and psychosocial problems among affected children. The aims of this study were to systematically review studies about effective support interventions for parentally bereaved children and to identify gaps in the research. METHODS: The review's inclusion criteria were comparative studies with samples of parentally bereaved children...

BACKGROUND: Medication and psychotherapy treatments for posttraumatic stress disorder (PTSD) provide insufficient benefit for many patients. Substantial preclinical and clinical data indicate abnormalities in the hypothalamic-pituitary-adrenal axis, including signaling by corticotropin-releasing factor, in the pathophysiology of PTSD. METHODS: We conducted a double-blind, placebo-controlled, randomized, fixed-dose clinical trial evaluating the efficacy of GSK561679, a corticotropin-releasing factor receptor 1 (CRF1 receptor) antagonist in adult women with PTSD...

BACKGROUND: Recent technological advances offer an opportunity to further elucidate the complex cytokine network in Major Depressive Disorder (MDD). The objective of this study was to investigate the role of pro-inflammatory and anti-inflammatory cytokines in the mechanism of depressive disorders. Given the activating role of cytokines on the hypothalamic-pituitary-adrenal (HPA) axis, and the relevance of its regulation in MDD, we also analyzed the relationships between several cytokines and cortisol levels...

Adverse childhood experiences (ACE) enhance the risk for mental disorders, e.g. major depressive disorder (MDD). Increasing evidence suggests an association between ACE and impaired physical health, e.g. metabolic syndrome. The aim of this study was to assess several metabolic risk markers in healthy individuals with and without ACE and depressed patients with and without ACE. We examined glucose and insulin release in the oGTT in 33 women with MDD and ACE, 47 women with MDD without ACE, 21 women with ACE but no current or lifetime MDD and 36 healthy women without either MDD or ACE...

BACKGROUND: Suicide mortality is 12 times higher in psychotic patients compared to the general population. Identifying characteristic of suicidal patients among this group might help in preventing such behavior. AIMS: To assess the predictors of suicidal risk in patients hospitalized due to acute psychosis. METHODS: One hundred and fifty patients (age 18 - 60 years) admitted with acute psychotic features were recruited. Patients were evaluated clinically by The Arabic version of Mini International Neuropsychiatric Interview (M...

AIMS: Despite the considerable public health impact of bipolar disorder (BD), no psychosocial interventions have been systematically evaluated in its early prodromal stages. We describe the rationale, design and analytic methods for a 3-site randomized trial of family-focused treatment for youth at high risk (FFT-HR) for BD. METHODS: Participants (ages 9-17 years) have a diagnosis of unspecified BD or major depressive disorder, current mood symptoms and at least one first- or second-degree relative with a lifetime history of BD I or II...

OBJECTIVE: The Children's Depression Rating Scale-Revised (CDRS-R) is a valid instrument for the assessment of depressive symptoms in youth, but this measure is yet to be validated in Korea. Thus, the present study aimed to evaluate the validity of the Korean version of the CDRS-R and to determine its factor structures. METHODS: This study included 66 youths between 12 and 17 years of age who participated as part of an ongoing study investigating biomarkers of the antidepressant response and suicidal events in depressed youth...

Physiological and psychological underpinnings of suicidal behavior remain ill-defined and lessen timely diagnostic identification of this subgroup of patients. Arterial stiffness is associated with autonomic dysregulation and may be linked to major depressive disorder (MDD). The aim of this study was to investigate the association between arterial stiffness by photo-plethysmogram (PPG) in MDD with and without suicidal ideation (SI) by applying multiscale tone entropy (T-E) variability analysis. Sixty-one 10-min PPG recordings were analyzed from 29 control, 16 MDD patients with (MDDSI+) and 16 patients without SI (MDDSI-)...

We carried out whole-exome ultra-high throughput sequencing in brain samples of suicide victims who had suffered from major depressive disorder and control subjects who had died from other causes. This study aimed to reveal the selective accumulation of rare variants in the coding and the UTR sequences within the genes of suicide victims. We also analysed the potential effect of STR and CNV variations, as well as the infection of the brain with neurovirulent viruses in this behavioural disorder. As a result, we have identified several candidate genes, among others three calcium channel genes that may potentially contribute to completed suicide...

Many intercurrent factors may be involved in the modulation of the pain message and its expression, such as the previous experience of pain built along the life. In this study, we aimed to determine whether susceptibility to experimentally induced pain is differentially influenced by the individual previous painful experience in subjects with schizophrenia (SC) major depression (MD), and controls (C). METHODS: The SC (30), MD (32) and C (30) groups participated in experimental pain tests (application of pressure and induction of ischemia) after a semi-structured interview to make an inventory of the previous painful experiences, and the evaluation of anxiety either with autonomic (heart rate, blood pressure) or psychological (Hospital Anxiety Depression scale HAD) measures, and catastrophism...

PURPOSE: Major depressive disorder (MDD) is highly prevalent in patients with a chronic physical condition, and this comorbidity has a negative influence on quality of life, health care costs, self-care, morbidity, and mortality. Research has shown that collaborative care (CC) may be a cost-effective treatment. However, its cost-effectiveness in this patient group has not yet been established. Therefore, the aim of this study was to evaluate the cost-utility of CC for the treatment of comorbid MDD in chronically ill patients in the outpatient general hospital setting...

PURPOSE: Given the public health significance of poorly treatable co-morbid major depressive disorders (MDD) among patients with type 2 diabetes mellitus (DM2) and coronary heart disease (CHD), we need to investigate whether strategies to prevent the development of major depression could reduce its burden of disease. We therefore evaluated the effectiveness of a stepped-care program for subthreshold depression in comparison with usual care in patients with DM2 and/or CHD. METHODS: A cluster randomized controlled trial, with 27 primary care centers serving as clusters...

OBJECTIVES: Cognitive dysfunction is a key feature of major depressive (MDD) and bipolar (BD) disorders. However, rather than a single cognitive profile corresponding to each diagnostic categories, recent studies have identified significant intra- and cross-diagnostic variability in patterns of cognitive impairment. The goal of this study was to contribute to the literature on cognitive heterogeneity in mood disorders by identifying cognitive subprofiles in a population of patients with MDD, BD type I, BD type II, and healthy adults...
