The newly launched Research Domain Criteria (RDoC) emphasize specific mechanisms over diagnostic categories of psychopathology. In our view, RDoC provides a useful heuristic for mental health disorders, but does not capture the complexity of psychological data when proposed mechanisms are viewed as static entities. However, temporal and complex system dynamics may advance RDoC's utility. By investigating temporal patterns within trajectories and the interaction of complex networks, we propose that dynamic modeling provides comprehensive methods with which to investigate the etiopathology and maintenance of mental health disorders...

Western discourses about young people and sexuality centre around the concept of risk. Anxieties have been fuelled by the increasing popularity of social media and practices such as 'sexting' and watching 'sexually explicit' materials online. Research has shown however that such risk discourses mainly serve to moralise about, pathologise and police particular behaviours and children. In order to counter such paternalism, researchers advocated a reconceptualisation of youth not as passive victims, but as active agents who actively negotiate sexual experiences and discourses...

BACKGROUND: Physiological hyperarousal in social situations is a characteristic of individuals with social anxiety disorder (SAD), but so far it has been rarely studied as a biological risk for SAD. Here, we investigate whether children at high risk for SAD (because of their parents' SAD) display physiological hyperarousal while interacting with a stranger. Also, we examine whether early physiological hyperarousal is related to later child social anxiety. METHOD: One hundred and seventeen children took part in the stranger-approach task when they were 2...

Insufficient dietary intake of essential omega-3 polyunsaturated fatty acids (N-3), especially during critical stages of development, is well-associated with negative neurological and metabolic consequences. The increased availability and intake of foods rich in saturated fat coincides with reduced N-3 consumption, yet how N-3 dietary deficiency during perinatal development modulates motivation for palatable food and interacts with a high-fat diet to affect body weight and emotional states is not clear. Pregnant C57Bl6 mice and pups were subjected to diets either deficient or adequate (control) in N-3 until postnatal day 21...

REVIEW
Mari Sild, Edward S Ruthazer, Linda Booij
Despite intense ongoing research efforts, the etiology of psychiatric disorders remains incompletely understood. Among biological factors playing a role in Major Depressive Disorder (MDD) and Anxiety Disorders (ANX), emerging evidence points to the relevance of different types of glia cells and efficient neuron-glia interactions. Here, we review recent findings highlighting the involvement of central nervous system (CNS) glia in MDD and ANX etiology and treatment response. Additionally, several relatively underexplored topics will be discussed: 1) glial response to non-pharmacological therapies, 2) impact of early life adversity on glia, 3) influence of lifestyle factors on glia in the context of MDD and ANX, and 4) monitoring glial functions in patients...

Oxytocin (OT) has been reported to increase social contact, however some studies have related OT to reduced social contact, particularly with unfamiliar individuals. The underlying mechanisms of OT on social contact remain unclear. In this study, male mandarin vole (Microtus mandarinus), a socially monogamous rodent, was used as an animal model in which osmotic minipumps were used to intracerebroventricularly administer two continuous dosages of OT or saline for 12 consecutive days. We examined the effect of long-term OT treatment on social behavior, anxiety levels, and levels of oxytocin, vasopressin (AVP) and dopamine (DA) receptors, mRNA expression in the nucleus accumbens (NAcc), and medial amygdala (MeA)...

Deficits in social behaviour are common in psychopathological conditions e.g., depression, autism and schizophrenia. In rats, sociability, defined as the engagement of an animal in non-aggressive social contact with a conspecific in a neutral arena, is as a persistent trait. To elucidate the neuroanatomy of social behaviour in animal models, long term neuronal energy metabolism was studied in rats preselected for sociability levels. Rats were divided into groups with high, medium and low sociability levels (HS, MS and LS) according to the average score of three social interaction tests, and cerebral long-term energy metabolism was assayed with cytochrome oxidase histochemistry...

Postpartum depression (PPD), part of a larger spectrum of perinatal mood and anxiety disorders, affects up to 15% of women following the birth of an infant. Fathers may also be affected. PPD not only affects caregivers, but also impacts infants through mechanisms such as inadequate caregiver-infant interactions and non-adherence to safety practices. The negative impact on infants may extend across the life course through adulthood. This article seeks to move the needle toward universal screening for PPD using validated tools in pediatric primary care settings for new caregivers by making the legal and ethical case for this course of action in a manner that is both compelling and accessible for clinicians...

BACKGROUND: Comorbidities are common in patients with gout, yet qualitative research is lacking. The study objective was to examine the impact of gout on comorbidities. METHODS: Nine nominal groups were conducted. Patients with gout discussed and rank-ordered their concerns in response to the question, "How does gout or its treatment affect your other conditions and their treatment?" RESULTS: Nine nominal groups had 45 gout patients, with mean age 61 years (standard deviation (SD) 10...

Insufficient sleep, as well as the incidence of anxiety disorders, both peak during adolescence. While both conditions present perturbations in fear-processing-related neurocircuitry, it is unknown whether these neurofunctional alterations directly link anxiety and compromised sleep in adolescents. Fourteen anxious adolescents (AAs) and 19 healthy adolescents (HAs) were compared on a measure of sleep amount and neural responses to negatively valenced faces during fMRI. Group differences in neural response to negative faces emerged in the dorsal anterior cingulate cortex (dACC) and the hippocampus...

BACKGROUND AND OBJECTIVES: According to the well-established categorical perception (CP) of facial expressions, we decode complicated expression signals into simplified categories to facilitate expression processing. Expression processing deficits have been widely described in social anxiety (SA), but it remains to be investigated whether CP of expressions are affected by SA. The present study examined whether individuals with SA had an interpretation bias when processing ambiguous expressions and whether the sensitivity of their CP was affected by their SA...

There is a critical gap in our knowledge of the mechanisms that govern interactions between daily life experiences (e.g., stress) and metabolic diseases, despite evidence that stress can have profound effects on cardiometabolic health. Apolipoprotein A-IV (apoA-IV) is a protein found in chylomicrons (lipoprotein particles that transport lipids throughout the body) where it participates in lipid handling and the regulation of peripheral metabolism. Moreover, apoA-IV is expressed in brain regions that regulate energy balance including the arcuate nucleus...

OBJECTIVE: Previous studies on the association between hypothalamic-pituitary-adrenal axis (HPAA) activity and ADHD yielded inconsistent findings, particularly in younger children. This might be due to the heterogeneity of the disorder, making moderator effects of variables probable, which circumscribe more homogenous subgroups. There have been indications of moderator effects on this association by gender of child and exposure to family adversity. Moreover, difficulties in capturing long-term basal HPAA activity in younger children might have contributed to the inconsistencies...

Anxiety can be an adaptive response to potentially threatening situations. However, if experienced in inappropriate contexts, it can also lead to pathological and maladaptive anxiety disorders. Experimentally, anxiety can be induced in healthy individuals using the threat of shock (ToS) paradigm. Accumulating work with this paradigm suggests that anxiety promotes harm-avoidant mechanisms through enhanced inhibitory control. However, the specific cognitive mechanisms underlying anxiety-linked inhibitory control are unclear...
