#1
Lorenzo Biassoni, Marina Easty
Background: Nuclear medicine imaging explores tissue viability and function by using radiotracers that are taken up at cellular level with different mechanism. This imaging technique can also be used to assess blood flow and transit through tubular organs. Nuclear medicine imaging has been used in paediatrics for decades and this field is continuously evolving. Sources of data: The data presented comes from clinical experience and some milestone papers on the subject...

Increased motivation for highly rewarding food is a major contributing factor to obesity. Most of the literature focuses on the mesolimbic nuclei as the core of reward behavior regulation. However, the lateral hypothalamus (LH) is also a key reward-control locus in the brain. Here we hypothesize that manipulating glucagon-like peptide-1 receptor (GLP-1R) activity selectively in the LH can profoundly affect food reward behavior, ultimately leading to obesity. Progressive ratio operant responding for sucrose was examined in male and female rats, following GLP-1R activation and pharmacological or genetic GLP-1R blockade in the LH...

Molecular and cellular adaptations in nucleus accumbens (NAc) medium spiny neurons (MSNs) underlie stress-induced depression-like behavior, but the molecular substrates mediating cellular plasticity and activity in MSN subtypes in stress susceptibility are poorly understood. We find the transcription factor early growth response 3 (EGR3) is increased in D1 receptor containing MSNs of mice susceptible to social defeat stress. Genetic reduction of Egr3 levels in D1-MSNs prevented depression-like outcomes in stress susceptible mice by preventing D1-MSN dendritic atrophy, reduced frequency of excitatory input and altered in vivo activity...

Tourette Disorder (TD) is a childhood-onset neuropsychiatric and neurodevelopmental disorder characterized by the presence of both motor and vocal tics. The genetic architecture of TD is believed to be complex and heterogeneous. Nevertheless, DNA sequence variants co-segregating with TD phenotypes within multiplex families have been identified. This report examines whole exomes of affected and unaffected individuals in a multiplex TD family to discover genes involved in the TD etiology. We performed whole exome sequencing on six out of nine members in a three-generation TD multiplex family...

BACKGROUND: Psychomotor agitation (PMA) is a state of motor restlessness and mental tension that requires prompt recognition, appropriate assessment and management to minimize anxiety for the patient and reduce the risk for escalation to aggression and violence. Standardized and applicable protocols and algorithms can assist healthcare providers to identify patients at risk of PMA, achieve timely diagnosis and implement minimally invasive management strategies to ensure patient and staff safety and resolution of the episode...

The success and achievements in the area of neurosciences due to the development of neuroimaging, neurochemical and genome studies provide tasks for psychiatry determined by the necessity to develop new classifications of mental diseases, primarily ICD-11, specify clinical diagnostic criteria and rethink the essence of some mental disorders. In spite of the multiple direction of scientific opinions on the discussed issues, the development of modern psychiatry is characterized by intensive search of biological background of psychiatric disorders and elaboration of effective approaches to the diagnosis and treatment of mental diseases, including medical rehabilitation of patients...

REVIEW
Florian Ganglberger, Joanna Kaczanowska, Josef M Penninger, Andreas Hess, Katja Bühler, Wulf Haubensak
Functional neuroanatomical maps provide a mesoscale reference framework for studies from molecular to systems neuroscience and psychiatry. The underlying structure-function relationships are typically derived from functional manipulations or imaging approaches. Although highly informative, these are experimentally costly. The increasing amount of publicly available brain and genetic data offers a rich source that could be mined to address this problem computationally. Here, we developed an algorithm that fuses gene expression and connectivity data with functional genetic meta data and exploits cumulative effects to derive neuroanatomical maps related to multi-genic functions...

Currently, the diagnosis of psychiatric illnesses is based upon DSM-5 criteria. Although endophenotype-specificity for a particular disorder is discussed, the identification of objective biomarkers is ongoing for aiding diagnosis, prognosis, or clinical response to treatment. We need to improve the understanding of the biological abnormalities in psychiatric illnesses across conventional diagnostic boundaries. The present review investigates the innovative post-genomic knowledge used for psychiatric illness diagnostics and treatment response, with a particular focus on proteomics...

BACKGROUND: The possibility of using biological measures to predict the trajectory of symptoms among adolescent psychiatric inpatients has important implications. This study aimed to examine emotion regulation ability (measured via self-report) and a hypothesized proxy in resting-state functional connectivity [RSFC] between the amygdala and frontal brain regions as baseline predictors of internalizing symptom recovery during inpatient care. METHODS: 196 adolescents (61% female; Mage = 15...

This paper highlights the most recent publications, in the field of psychiatry, on offspring of patients with psychiatric illnesses such as schizophrenia and bipolar disorder, and then summarizes what we know about the progeny of adults with mood disorders, the most prevalent of parental disorders. Studies examining personality disorders and contextual factors such as stress and trauma are examined with a focus on the crucial question of development and attachment status in children. Findings converge to reveal that offspring of parents (generally mothers) with most major psychiatric disorders present a higher risk for all mental disorders, and a wide range of disorders are also found in children, adolescent, and finally adult offspring of mothers with mood and anxiety disorders...

Following its inception, electroconvulsive therapy (ECT), rapidly spread all over the world, including Nazi Germany. Paradoxically, at the same time, the euthanasia programme was started in Germany: the extermination of people with intellectual disabilities and severe psychiatric disorders. In Lower Austria, Dr Emil Gelny, who had been granted a specialist qualification in psychiatry after three months of clinical training, took control of two psychiatric hospitals, in Gugging and Mauer-Öhling. In 1944, he began systematically killing patients with an ECT machine, something that was not practised anywhere else before or after, and remains unprecedented in the history of convulsive therapy...

Major depression represents among the most frequent psychiatric disorders in the general population with an estimated lifetime prevalence of 16-17%. It is characterized by high levels of comorbidities with other psychiatric conditions or somatic diseases as well as a recurrent or chronic course in 50 to 80% of the cases leading to negative repercussions on the daily functioning, with an impaired quality of life, and to severe direct/indirect costs. Large cohort studies have supported that failure of a first-line antidepressant treatment is observed in more than 60% of patients...

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...

Suicide remains a clear, present and increasing public health problem, despite being a potentially preventable tragedy. Its incidence is particularly high in people with overt or un(der)diagnosed psychiatric disorders. Objective and precise identification of individuals at risk, ways of monitoring response to treatments and novel preventive therapeutics need to be discovered, employed and widely deployed. We sought to investigate whether blood gene expression biomarkers for suicide (that is, a 'liquid biopsy' approach) can be identified that are more universal in nature, working across psychiatric diagnoses and genders, using larger cohorts than in previous studies...

Knowledge of psychiatric disease genetics has advanced rapidly during the past decade with the advent of genome-wide association studies (GWAS). However, less progress has been made in harnessing these data to reveal new therapies. Here we propose a framework for drug repositioning by comparing transcriptomes imputed from GWAS data with drug-induced gene expression profiles from the Connectivity Map database and apply this approach to seven psychiatric disorders. We found a number of repositioning candidates, many supported by preclinical or clinical evidence...

This review presents the recently published revised classifications of epilepsies and seizure types developed by the International League Against Epilepsy (ILAE). The Classification of Epilepsies includes several diagnostic levels (steps): 1) from seizure type to epilepsy type (generalized/focal/combined generalized and focal/unknown), 2) diagnosis of epilepsy syndrome 3) etiology (genetic/ structural/ infectious/ metabolic/ immune/unknown). A clinician can use any level of the classification. Operational classification of seizure types is replaced by the previous classification that was grounded on the anatomical basis...

Qualitative analysis of the family system including a person suffering from schizophrenia is an underestimated research paradigm in modern psychiatry, clinical psychology and psychotherapy. This method is important both from the cognitive point of view and for evaluation of the effectiveness of therapy. AIM: The aim of the study was a qualitative analysis of the therapeutic process in a family whose member is suffering from schizophrenic psychosis. MATERIALS AND METHODS: The study of the process using qualitative research methodology in the paradigm of systemic thinking pointing to the mutual interactions in the family system inducing relapses in the identified patient, with identification of triangulation processes, transgenerational myths inheritance and coalitions formed by the family members...

49,XXXXY and 45,X syndromes are sex chromosome aneuploidies in which the affected individuals present with hypergonadotropic hypogonadism, short or long stature, and skeletal malformations. Psychological, endocrinological, and orthopaedic disorders constitute the major problems in the clinical follow-up. We report a family with two rare entities: 49,XXXXY and 45, X. Sex chromosome abnormalities should especially be in mind in the evaluation of patients with micropenis, mental retardation, and hypergonadotropic hypogonadism...
