Major depressive disorder (MDD) has been linked to mitochondrial defects, which could manifest in mitochondrial DNA (mtDNA) polymorphisms or mutations. Additionally, copy number of mtDNA (mtDNA-cn) can be quantified in peripheral blood mononuclear cells (PBMC)s, indirectly reflecting cellular energetics, or in the circulating cell-free mtDNA (ccf-mtDNA) levels, which may reflect a fraction of the mitochondrial genome released during cellular stress. Few studies have examined ccf-mtDNA in MDD, and no studies have tested its relationship with intracellular mtDNA-cn or with antidepressant treatment response...

OBJECTIVES: We aimed to investigate morphometric correlates of auditory hallucinations in bipolar disorder (BD) by comparing cortical thickness and cortical surface area in bipolar disorder patients with (BD+) and without (BD-) a lifetime history of auditory hallucinations. Based on previous findings in schizophrenia patients, we hypothesized that the cortex would be thinner in the auditory cortex in BD+ compared to BD-. METHODS: Bipolar disorder spectrum (n = 157) patients and healthy controls (n = 279) underwent 1...

PURPOSE: To assess rural-urban differences in healthcare utilization and supportive care at the end-of-life in German lung cancer patients. METHODS: We identified 12,929 patients with incident lung cancer in 2009 from claims data and categorized them to four district types (major city, urban, rural, remote rural). We compared site of death, unplanned hospitalizations, hospital days, outpatient doctor, general practitioner (GP) and home visits, structured palliative care, therapy with antidepressants, pain relief medication and chemotherapy, and therapeutic puncturing in the last 30 and 14 days of life using mixed models with logistic link function for binary outcomes and log link function for count data...

Studies on the subjective effects of antidepressants suggest that they may not only improve depressed mood, but as an adverse effect also cause "emotional blunting." This phenomenon is poorly understood and little studied. The aim of this study was to examine the association of serotonergic antidepressant use and subjective emotional awareness. Emotional awareness was assessed using the Difficulty Identifying Feelings subscale from the 20-Item Toronto Alexithymia Scale. Fifty-seven individuals on antidepressant medication and 441 controls were compared...

BACKGROUND: It is unknown whether newer, mainly selective serotonin reuptake inhibitors, and older tricyclic antidepressants are used similarly regardless of the geographical area of residence and education. METHODS: We included four randomly sampled cohorts of the Finnish working aged population (n = 998,540-1,033,135). The sampling (Dec 31st in 1995, 2000, 2004 and 2010) resulted in non-overlapping time windows where each participant was followed up for four years for the first antidepressant use...

Activation of immune-inflammatory and oxidative-nitrosative (IO&NS) stress pathways plays a role in major depression (MDD). Evidence suggests that curcumin (500-1000 mg/day), a polyphenol with strong anti-IO&NS properties, may have efficacy either as monotherapy or as an adjunctive treatment for depression. Further controlled trials with extended treatment periods (> 8 weeks) and higher curcumin doses are warranted. This 12-week study was carried out to examine the effects of adjunctive curcumin for the treatment of MDD...

BACKGROUND: Hospitalization accounts for significant health care resource utilization for treatment-resistant Bipolar Disorder (BD), especially among frequent users of acute inpatient psychiatric units. Appraisal of the clinical features and predictive role of selected variables is therefore crucial in such population, representing the aim of the present research. METHODS: A hundred and nineteen BD inpatients with an established history of pharmacological treatment resistance for either mania or bipolar depression were classified as long hospitalization cases (LOS+) and their controls and compared against each other for a number of demographic, clinical, and psychopathological features...

Despite a wide range of reports on depression-induced P300 changes, it is still debatable whether P300 can return to a pattern characteristic of healthy individuals following antidepressant treatment. Thus, the present study aims to compare P300 and its underlying neural activation in depressed patients before and after antidepressant treatment to explore the brain regions related to pathogenesis and to evaluate the prognosis after treatment. P300 was evoked by the oddball auditory paradigm and collected from 14 sex-matched, age-matched, and education level-matched patients and controls...

Background: Antipsychotic (AP) medication is increasingly used for many health conditions. Prenatal exposure to AP medication has been associated with several adverse outcomes, but the findings remain inconsistent. Purpose: We aimed to investigate prenatal exposure to AP medication and the use of primary health care system in childhood. Subjects and methods: All live-born singletons in Denmark during 1997-2012 were identified in the nationwide Danish National Patient Register and followed until December 31, 2013 (n = 963,010)...

BACKGROUND: PDE4 cyclic nucleotide phosphodiesterases regulate 3', 5' cAMP abundance in the CNS and thereby regulate PKA activity and phosphorylation of CREB, which has been implicated in learning and memory, depression and other functions. The PDE4 isoform PDE4B1 also interacts with the DISC1 protein, implicated in neural development and behavioral disorders. The cellular functions of PDE4B1 have been investigated extensively, but its function(s) in the intact organism remained unexplored...

Vortioxetine is a novel antidepressant with multimodal activity currently approved for the treatment of major depressive disorder. Vortioxetine is orally administered once daily at 5- to 20-mg doses. The pharmacokinetics of vortioxetine are linear and dose proportional, with a mean terminal half-life of approximately 66 h and steady-state plasma concentrations generally achieved within 2 weeks of dosing. The mean absolute oral bioavailability of vortioxetine is 75%. No food effect on pharmacokinetics was observed...

Despite the high prevalence of panhypopituitarism and diabetes insipidus in patients with craniopharyngioma (CP), little is known about the functioning of the neuropeptide oxytocin in these patients. This is of special interest as tumor-associated lesions often impair sites critical for oxytocin production and release, and affective dysfunction in CP links with elsewhere reported prosocial, antidepressant and anxiolytic oxytocin effects. Using a prospective study-design, we tested whether oxytocin is reduced in CP-patients, and whether altered oxytocin levels account for affective and emotional dysfunction...

RATIONALE: Low-dose ketamine is a rapid-acting antidepressant, to which female rodents are more sensitive as compared to males. However, the mechanism mediating this sex difference in ketamine sensitivity remains elusive. OBJECTIVES: We sought to determine whether male and female mice differ in their behavioral sensitivity to low doses of ketamine, and uncover how ovarian hormones influence females' ketamine sensitivity. We also aimed to uncover some of the molecular mechanism(s) in mood-related brain regions that mediate sex differences in ketamine antidepressant effects...

Clinical evidences show sex differences in risk of developing depressive disorders as well as effect of antidepressants in depression treatment. However, whether such a sex-dependent risk of depression and efficacy of antidepressants is dependent on endogenous estrogen level remain elusive. The aim of this study is to explore the molecular mechanisms of sex differences in antidepressant duloxetine. In the present study, we used genetic knockout or overexpression estrogen-synthesizing enzyme aromatase (Ar) gene as models for endogenous estrogen deficiency and elevation endogenous estrogen, respectively, to examine the anti-depressive efficacy of duloxetine in males and females by force swimming test (FST)...

Background and aims: Selective serotonin reuptake inhibitors (SSRIs) are antidepressants increasingly prescribed against depression during and after pregnancy. However, these compounds cross the placenta and are found in breast milk, thus reaching, and possibly affecting, the fetus and infant during critical developmental stages. Fluoxetine (FLX), a widely used SSRI, can interfere with estrogen signaling, which is important for the development of female sex organs and certain brain areas, among others...
