Psychotic disorders are heterogeneous and complex, involving many putative causal factors interacting along the course of disease development. Many of the factors implicated in the pathogenesis of psychosis also appear to be involved in disease onset and subsequent neuroprogression. Herein, we highlight the pertinent literature implicating inflammation and oxidative stress in the pathogenesis of psychosis, and the potential contribution of N-methyl-D-aspartate receptors (NMDARs). We also emphasize the role of peripubertal social stress in psychosis, and the ways in which hippocampal dysfunction can mediate dysregulation of the hypothalamic-pituitary-adrenal axis and cortisol release...

When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social-emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment...

A common practice when analyzing multi-site epidemiological data is to include a term for 'site' to account for unmeasured effects at each location. This practice should be carefully considered when site can have complex relationships with important demographic and exposure variables. We leverage data from three longitudinal North American pregnancy cohorts to demonstrate a novel method to assess study heterogeneity and potential combinability of studies for pooled analyses in order to better understand how to consider site in analyses...

BACKGROUND: Acute upper extremity injuries remain one of the most common consultations in the emergency departments for plastic surgery services. These injuries can affect a person's quality of life and negatively affect work-related or social interactions if not properly managed. We aim to evaluate our experience and management in a specialized referral center in Mexico City. METHODS: A retrospective review was performed. All patients with hand trauma managed by our service from July 2010 to June 2015 were included; their demographic characteristics were described as well as the most common patterns of injury, management, and outcome...

Knowledge gaps revealed among young people during this survey confirm that this age-group should be targeted by a specifically tailored approach. Responders are receptive to information provided by reliable and easily accessible sources. High schools, as well as general practitioners, play an important role in health education in general for this age-group and particularly concerning antibiotics and vaccinations. The Internet is a relevant medium for disseminating information. Teaching should be interactive and take social influences (peers, family) into account...

Some studies have found that women outperform men in episodic memory after midlife. But is this finding universal, and what are the reasons? Gender differences in cognition are the result of biopsychosocial interactions throughout the life course. Social-cognitive theory of gender development posits that gender roles may play an important mediating role in these interactions. We analyzed country differences in the gender differential in cognition after midlife using data from individuals age 50 and above ( N = 226,661) from 27 countries...

We introduce a form of Self-Organized Criticality (SOC) inspired by the new generation of evolutionary game theory, which ranges from physiology to sociology. The single individuals are the nodes of a composite network, equivalent to two interacting subnetworks, one leading to strategy choices made by the individuals under the influence of the choices of their nearest neighbors and the other measuring the Prisoner's Dilemma Game payoffs of these choices. The interaction between the two networks is established by making the imitation strength K increase or decrease according to whether the last two payoffs increase or decrease upon increasing or decreasing K...

OBJECTIVES: The nature of patient-provider interactions and communication is widely documented to significantly impact on patient experiences, treatment adherence and health outcomes. Yet little is known about the broader contextual factors and dynamics that shape patient-provider interactions in high HIV prevalence and limited-resource settings. Drawing on qualitative research from five sub-Saharan African countries, we seek to unpack local dynamics that serve to hinder or facilitate productive patient-provider interactions...

Oxytocin (OT) is a critical molecule for social recognition that mediates social and emotional behaviors. OT is released during stress and acts as an anxiolytic factor. To know the precise molecular mechanisms underlying OT release into the brain during stress is important. It has been reported that intracellular concentrations of free calcium in the hypothalamic neurons are elevated by simultaneous stimulation of cyclic ADP-ribose (cADPR) and heat. We have reported in vitro and in vivo data that supports the idea that release of OT in the brain of male mice is regulated by cADPR and fever in relation to stress conditions...

The present article examined the development of relational aggression in middle childhood and the effects of observed teacher behavior on this development. Relying on social learning theory, we expected that teacher praise would slow down the increase of relational aggression, whereas teacher reprimands would promote the increase of relational aggression. A sample of 570 children (49% boys, Mage=7years and 5months, >95% Belgian) was followed from second to fourth grade. Teacher praise and reprimands were observed at the beginning of second grade...

OBJECTIVES: Breathlessness is a major problem for people in their last weeks of life. Breathlessness is considered to be multidimensional with physical, psychological, emotional, social and spiritual factors all playing a part. It has been recognised that specific training to health professionals is beneficial in order to improve the care for patients with breathlessness.Breathlessness courses have tended to focus on senior nurses. A new flexible and collaborative training course was designed to include a wider range of nurses and other health professionals in hospital, hospice, primary care and community settings...

Selective serotonin reuptake inhibitor medications (SSRIs) are the first lines of treatment for maternal affective disorders, and are prescribed to up to 10% of pregnant women. Concern has been raised about how perinatal exposure to these medications affect offspring neurobehavioral outcomes, particularly those related to social interactions, as recent research has reported conflicting results related to autism spectrum disorder (ASD) risk in children prenatally exposed to SSRIs. Therefore, the aim of this work was to investigate the effects of perinatal exposure to the SSRI fluoxetine on social play behaviors and the hypothalamic pituitary adrenal system, using a model of pre-gestational maternal stress...

In social interactions, we often need to quickly infer why other people do what they do. More often than not, we infer that behavior is a result of personality rather than circumstances. It is unclear how the tendency itself may contribute to psychopathology and interpersonal dysfunction. Borderline personality disorder (BPD) is characterized by severe interpersonal dysfunction. Here, we investigated if this dysfunction is related to the tendency to over-attribute behaviors to personality traits. Healthy controls and patients with BPD judged positive and negative behaviors presented within a situational constraint during functional magnetic resonance imaging...

Language that describes actions, for instance verbs, can help to predict future actions of conspecifics in social interactions. Language and action are therefore interrelated. This interrelation has been described on a behavioral level for adults and toddlers. Furthermore, in adults, the sensorimotor system is involved in this interrelation. However, little is known about the early interrelation on the neural level at the onset of verb acquisition. In the present study, we examined the role of the sensorimotor system during the processing of acoustically presented verbs that describe dynamic actions and visually presented actions in toddlers, who are in the earliest stage of expressive language development...

BACKGROUND AND AIM: Understanding the experience of initiating injection drug use and its social contexts is crucial to inform efforts to prevent transitions into this mode of drug consumption and support harm reduction. We systematically reviewed and synthesized existing qualitative scientific literature to identify the socio-structural contexts for, and experiences of, the initiation of injection drug use. METHODS: We systematically searched six databases (Medline, Embase, PsychINFO, CINAHL, IBSS, and SSCI), along with a manual search, including of key journals and subject experts...

Valproic acid (VPA)-exposed rat offspring have demonstrated autism spectrum disorder (ASD) phenotypes and impaired N-methyl-D-aspartate receptor (NMDAR)-dependent long-term depression (LTD) in the lateral nucleus of the amygdala. NMDAR partial agonist D-cycloserine (DCS) has been reported to act as a cognitive enhancer by increasing the NMDAR response to improve autistic-like phenotypes in animals. However, the mechanism of DCS in alleviating the ASD is still unknown. Using combined behavioral, electrophysiological, and molecular approaches, we found that DCS administration rescued social interaction deficits and anxiety/repetitive-like behaviors observed in VPA-exposed offspring...

As the identity of a large number of Khoe-San skeletal material in European collections recently came into question during its documentation, a re-evaluation of the remains by employing a non-invasive method such as craniometrics was done to investigate the biological affinity. For this purpose, gene flow and population diversity present within the group, as well as between the study sample (N=63) and other modern and historic population groups from southern, central and east Africa were explored. Available comparative groups included the historic Khoe-San from Riet River (N=31), the Sotho-Tswana from southern Africa (N=61), the Basuku from central Africa (N=66) and the Bahutu (N=53) and Teita (N=24) from east Africa...
