#1
M J Ramaker, S C Dulawa
Depression is a leading cause of disability worldwide and a major contributor to the burden of suicide. A major limitation of classical antidepressants is that 2-4 weeks of continuous treatment is required to elicit therapeutic effects, prolonging the period of depression, disability and suicide risk. Therefore, the development of fast-onset antidepressants is crucial. Preclinical identification of fast-onset antidepressants requires animal models that can accurately predict the delay to therapeutic onset. Although several well-validated assay models exist that predict antidepressant potential, few thoroughly tested animal models exist that can detect therapeutic onset...

Parvalbumin inhibitory interneurons (PVIs) are crucial for maintaining proper excitatory/inhibitory balance and high-frequency neuronal synchronization. Their activity supports critical developmental trajectories, sensory and cognitive processing, and social behavior. Despite heterogeneity in the etiology across schizophrenia and autism spectrum disorder, PVI circuits are altered in these psychiatric disorders. Identifying mechanism(s) underlying PVI deficits is essential to establish treatments targeting in particular cognition...

Numerous genetic and functional studies implicate variants of Neuregulin-1 (NRG1) and its neuronal receptor ErbB4 in schizophrenia and many of its endophenotypes. Although the neurophysiological and behavioral phenotypes of NRG1 mutant mice have been investigated extensively, practically nothing is known about the function of NRG2, the closest NRG1 homolog. We found that NRG2 expression in the adult rodent brain does not overlap with NRG1 and is more extensive than originally reported, including expression in the striatum and medial prefrontal cortex (mPFC), and therefore generated NRG2 knockout mice (KO) to study its function...

Children who have suffered early abuse or neglect may later present with significant health and behavior problems that may persist long after the abusive or neglectful environment has been remediated. Neurobiological research suggests that early maltreatment may result in an altered psychological and physiologic response to stressful stimuli, a response that deleteriously affects the child's subsequent development. Pediatricians can assist caregivers by helping them recognize the abused or neglected child's emotional and behavioral responses associated with child maltreatment and guide them in the use of positive parenting strategies, referring the children and families to evidence-based therapeutic treatment and mobilizing available community resources...

BACKGROUND: One of the major challenges in mental medical care is finding out new instruments for an accurate and objective evaluation of the attention deficit hyperactivity disorder (ADHD). Early ADHD identification, severity assessment, and prompt treatment are essential to avoid the negative effects associated with this mental condition. OBJECTIVE: The aim of our study was to develop a novel ADHD assessment instrument based on Microsoft Kinect, which identifies ADHD cardinal symptoms in order to provide a more accurate evaluation...

The antiapoptotic protein Bcl-xL is involved in development of neurobiological resilience to stress; hence, the possibility of use of psychotropic drugs to increase its expression in brain in response to stress is of considerable interest. Lithium is a neurotropic drug widely used in psychiatry. In work, we studied effects of lithium administration (for 2 or 7 days) on the expression of Bcl-xL mRNA and protein in the hippocampi and cortices of rats subjected to stress that induced depression-like behavior in the animals...

Bipolar disorders belong to the spectrum of mood disorders and represent a serious psychiatric comorbidity. Behaviors adopted by bipolar patients can foster cancer occurrence but also impact its management, especially during acute depressive or manic episode. Oncologists must adapt their protocols in order to obtain the best compliance for treatment and avoid any possible mood destabilization, with the inherent risk of suicidal attempt. Potential interactions between mood-stabilizing agents (lithium, divalproate, atypical antipsychotics, and anticonvulsivants) and oncologic treatment (chemotherapy, targeted therapy, immunotherapy, corticotherapy) will be particularly watched...

WHAT IS KNOWN AND OBJECTIVES: Psychopharmacologic therapy has so far focused on ameliorating disruptive behaviours to improve patient's function and quality of life. Due to the complicated neurobiological aetiology of autism spectrum disorder (ASD), a traditional pharmacist intervention may be insufficient to initiate the optimal care for this vulnerable population. We evaluate the impact of providing specialty psychiatry (PS) pharmacist intervention in identifying and resolving drug-related problems (DRPs) among children with ASD associated with disruptive behaviours...

Although violations of laws, such as shoplifting, are considered to be common in frontotemporal dementia (FTD) patients, there have been few studies on this subject and the frequencies and types of such violations have not been clarified. The objective of this study was to conduct a retrospective investigation of FTD patients in the psychiatry departments of multiple institutions to determine the types and frequencies of any law violations and compare them with those of AD patients. All patients were examined between January 2011 and December 2015 at the specialized dementia outpatient clinics of 10 facilities (5 psychiatry departments of university hospitals, 5 psychiatric hospitals)...

REVIEW
Donatella Marazziti
Serotonin (5-HT) continues to attract researchers' interest after almost a century. However, despite these efforts, its role has not yet been fully elucidated. It is now evident that 5-HT does not modulate single functions but rather a multiplicity of activities and behaviors present in both normal and several pathological conditions in a less deterministic way than previously assumed. This article aims to briefly review some of the latest advancements in the general role of 5-HT in psychiatry, particularly in depression, and offer the author's personal reflections...

BACKGROUND: War veterans with PTSD have a high chance of developing major depressive disorder (MDD) at some point, while they can also exhibit increased suicidal tendencies. The primary goal of this research was to investigate whether personality dimensions, including temperament, character, and trait impulsivity, were associated with comorbid MDD, as well as with suicidal ideation in psychiatric patients suffering from combat-related PTSD. SUBJECTS AND METHODS: The sample consisted of 148 Croatian male war veterans (mean age 49...

BACKGROUND: Historically, the function of psychiatry and psychotherapy in the healthcare treatment of transsexualism has been impaired by the basic assumption that non-conforming gender experiences and behavior are automatically considered as expressions of psychopathology. OBJECTIVE: In line with revision of the diagnostic criteria and changing standards of care and treatment recommendations, the therapeutic relationship between mental healthcare professionals and transgender individuals is critically discussed aiming at providing a needs-based psychiatric and psychotherapeutic treatment and a patient-centered approach for trans persons...

A S Zannas, G P Chrousos
Psychosocial stress triggers a set of behavioral, neural, hormonal, and molecular responses that can be a driving force for survival when adaptive and time-limited, but may also contribute to a host of disease states if dysregulated or chronic. The beneficial or detrimental effects of stress are largely mediated by the hypothalamic-pituitary axis, a highly conserved neurohormonal cascade that culminates in systemic secretion of glucocorticoids. Glucocorticoids activate the glucocorticoid receptor, a ubiquitous nuclear receptor that not only causes widespread changes in transcriptional programs, but also induces lasting epigenetic modifications in many target tissues...

Imaging genetics and genomics research has begun to provide insight into the molecular and genetic architecture of neural phenotypes and the neural mechanisms through which genetic risk for psychopathology may emerge. As it approaches its third decade, imaging genetics is confronted by many challenges, including the proliferation of studies using small sample sizes and diverse designs, limited replication, problems with harmonization of neural phenotypes for meta-analysis, unclear mechanisms, and evidence that effect sizes may be more modest than originally posited, with increasing evidence of polygenicity...

Epigenetics is the branch of genetics that studies the dynamic relationship between stable genotypes and varying phenotypes. To this end, epigenetics aims to discover the molecular mechanisms that explain how different nutrients and hormones, environmental changes, and emotional, social and cognitive experiences modify gene expression and behaviors, even permanently so. Psychiatry has learned that diseases with strong genetic predisposition, such as schizophrenia, show a concordance of around 50% between monozygotic twins, thus evidencing the importance of the genetic background and the presence of environmental variables that stimulate or block phenotypic development...

REVIEW
Kimberly A Mulligan, Benjamin N R Cheyette
Mounting evidence indicates that Wnt signaling is relevant to pathophysiology of diverse mental illnesses including schizophrenia, bipolar disorder, and autism spectrum disorder. In the 35 years since Wnt ligands were first described, animal studies have richly explored how downstream Wnt signaling pathways affect an array of neurodevelopmental processes and how their disruption can lead to both neurological and behavioral phenotypes. Recently, human induced pluripotent stem cell (hiPSC) models have begun to contribute to this literature while pushing it in increasingly translational directions...

Ecological momentary assessment (EMA) is gaining importance in psychiatry. This article assesses the characteristics of patients who used a new electronic EMA tool: the MEmind Wellness Tracker. Over one year, 13811 adult outpatients in our Psychiatry Department were asked to use MEmind. We collected information about socio-demographic data, psychiatric diagnoses, illness severity, stressful life events and suicidal thoughts/behavior. We compared active users (N = 2838) and non-active users (N = 10,973) of MEmind and performed a Random Forest analysis to assess which variables could predict its use...
