As an opportunistic fungal pathogen Candida spp. has the ability to form biofilms. The most prescribed drugs for Candida infections, azoles, have shown to be less effective when biofilms are present. In addition, increasing treatment costs and the fact that most prescribed antifungal drugs have only fungistatic activity justify the search for new treatment strategies. One promising approach is third generation antidepressants, selective serotonin re-uptake inhibitors (SSRIs), because of their proven antifungal activity against several Candida spp...

Animals respond to predators by altering their behavior and physiological states, but the underlying signaling mechanisms are poorly understood. Using the interactions between Caenorhabditis elegans and its predator, Pristionchus pacificus, we show that neuronal perception by C. elegans of a predator-specific molecular signature induces instantaneous escape behavior and a prolonged reduction in oviposition. Chemical analysis revealed this predator-specific signature to consist of a class of sulfolipids, produced by a biochemical pathway required for developing predacious behavior and specifically induced by starvation...

This study aimed to evaluate if efficacy and tolerability of switching to vortioxetine is independent of previous SSRI or SNRI treatment in patients who had been inadequately treated for their current major depressive episode. Patients from a double-blind, 12-week comparator study were randomized (1:1) to vortioxetine (10-20 mg/day) or agomelatine (25-50 mg/day). The pre-defined primary efficacy endpoint was change from baseline to week 8 in MADRS total score analyzed by MMRM. An ANCOVA-LOCF was conducted as a sensitivity analysis...

BACKGROUND: Research suggests that individuals with anxiety have difficulty ignoring threat distractors when completing tasks with competing stimuli. Studies examining the neural correlates of these emotional processing difficulties in youth anxiety highlight reduced recruitment of regions associated with goal-directed attention, such as the anterior cingulate cortex (ACC). In the current study, we examined neural activation during an emotional conflict task in youth with anxiety disorders before and after treatment...

BACKGROUND: Ritualistic behaviors are common in obsessive compulsive disorder (OCD), while catatonic stupor occasionally occurs in psychotic or mood disorders. Schizoaffective disorder is a specific mental disorder involving both psychotic and affective symptoms. The syndrome usually represents a specific diagnosis, as in the case of the 10th edition of the International Classification of Diseases (ICD-10) or the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5)...

In the second part we focus on two treatment strategies that may overcome the main limitations of current antidepressant drugs. First, we review the experimental and clinical evidence supporting the use of glutamatergic drugs as fast-acting antidepressants. Secondly, we review the involvement of microRNAs (miRNAs) in the pathophysiology of major depressive disorder (MDD) and the use of small RNAs (e.g.., small interfering RNAs or siRNAs) to knockdown genes in monoaminergic and non-monoaminergic neurons and induce antidepressant-like responses in experimental animals...

Default mode network (DMN) dysfunction (particularly within the anterior cingulate cortex (ACC) and medial prefrontal cortex (mPFC)) has been implicated in major depressive disorder (MDD); however, its contribution to treatment outcome has not been clearly established. Here we tested the role of DMN functional connectivity as a general and differential biomarker for predicting treatment outcomes in a large, unmedicated adult sample with MDD. Seventy-five MDD outpatients completed fMRI scans before and 8 weeks after randomization to escitalopram, sertraline, or venlafaxine-XR...

OBJECTIVE: Several countries have developed Clinical Practice Guidelines regarding treatment of perinatal depressive symptoms and perinatal use of antidepressant. We aimed to compare guidelines to guide clinicians in best clinical practice. METHODS: An extensive search in guideline databases, MEDLINE and PsycINFO was performed. When no guidelines were (publicly) available online, we contacted psychiatric-, obstetric-, perinatal- and mood disorder societies of all first world countries and the five largest second world countries...

The objective of this study was to evaluate the prevalence and relative risk of off-label prescription of antidepressants in Chinese pediatric outpatients according to China Food and Drug Administration (C-FDA) and USFDA regulations. Medical records of 18 459 pediatric outpatients were identified between 2013 and 2015. Patient characteristics, prevalence of off-label antidepressant prescriptions, and relative risk factors associated with off-label prescribing were analyzed. The results indicate that patients aged from 12 to 17 years account for 88...

OBJECTIVE:  Psychopharmacotherapy is essential in the treatment of many mental disorders. Adverse drug reactions (ADR) have impact on compliance and tolerability. Sleep disorders or impaired sleep may occur as ADRs of psychopharmacotherapy. Sleep disorders are associated with an increased risk for physical and mental illness and may impair cognition, impulse control, emotion regulation and mood. Objective of the following study was the systematic presentation of type and risk of sleep disorders/impairments of sleep of frequently prescribed psychotropic drugs...

The distribution of micropollutants in biotic phases of horizontal sub-surface flow (HSSF) constructed wetlands was investigated. 88 diverse micropollutants (personal care products, pharmaceuticals and illicit drugs) were monitored for in full-scale HSSF steel slag and gravel beds to assess their fate and behaviour during tertiary wastewater treatment. Of the studied micropollutants 54 were found in receiving and treated wastewaters. Treatment reduced concentrations of several micropollutants by >50% (removal range -112% to 98%) and resulted in changes to the stereo-isomeric composition of chiral species...

Failure in fear extinction is one of the more troublesome characteristics of posttraumatic stress disorder (PTSD). Cotinine facilitates fear memory extinction and reduces depressive-like behavior when administered 24 h after fear conditioning in mice. In this study, it was investigated the behavioral and molecular effects of cotinine, and other antidepressant preparations infused intranasally. Intranasal (IN) cotinine, IN krill oil, IN cotinine plus krill oil, and oral sertraline were evaluated on depressive-like behavior and fear retention and extinction after fear conditioning in C57BL/6 mice...

In this article, we describe the case of a girl who suffers from a phobia to repetitive patterns, known as trypophobia. This condition has not yet been recognised by diagnostic taxonomies such as the Diagnostic and Statistical Manual of Mental Disorders. Trypophobia usually involves an intense and disproportionate fear towards holes, repetitive patterns, protrusions, etc., and, in general, images that present high-contrast energy at low and midrange spatial frequencies. It is commonly accompanied by neurovegetative symptoms...

BACKGROUND: Major depressive disorder is one of the most common, burdensome, and costly psychiatric disorders worldwide in adults. Pharmacological and non-pharmacological treatments are available; however, because of inadequate resources, antidepressants are used more frequently than psychological interventions. Prescription of these agents should be informed by the best available evidence. Therefore, we aimed to update and expand our previous work to compare and rank antidepressants for the acute treatment of adults with unipolar major depressive disorder...

BACKGROUND: Many pharmacoepidemiologic studies using large-scale databases have recently been utilized to evaluate the safety and effectiveness of drugs in Western countries. In Japan, however, conventional methodology has been applied to postmarketing surveillance (PMS) to collect safety and effectiveness information on new drugs to meet regulatory requirements. Conventional PMS entails enormous costs and resources despite being an uncontrolled observational study method. This study is aimed at examining the possibility of database research as a more efficient pharmacovigilance approach by comparing a health care claims database and PMS with regard to the characteristics and safety profiles of sertraline-prescribed patients...
