Interpersonal dysfunction is central to borderline personality disorder (BPD). Recent research has focused on the role of oxytocin (OT) in BPD, particularly regarding associations of OT activity with symptoms, genetic polymorphisms of the oxytocin receptor coding gene (OXTR) in BPD, and experimental modification of interpersonal core problems of patients with BPD such as hypervigilance towards threat detection, mistrust, and non-verbal behaviour during social interaction by intranasal application of OT. ⋯ The study of oxytocin can contribute to the understanding of the neurobiology of borderline personality disorder. Oxytocin is critically involved in attachment security, and methylation of the oxytocin receptor may play a role in the epigenetic modulation of early adversity. The intranasal application of oxytocin may be a useful therapeutic adjunct to psychotherapy. Insecure attachment and childhood adversity may produce differential neurobiological effects on the oxytocinergic system in borderline personality disorder. There is insufficient knowledge of how oxytocin interacts with vasopressin, testosterone, dopamine, and serotonin, which are also important key players in the experience of social reward and stress responsivity. It is unclear whether or not oxytocin could be beneficial in preventing the intergenerational (non-genetic) transmission of borderline personality traits.

Imagining future events, which contain episodic and non-episodic details, has been found to (1) engage the temporal lobes bilaterally and (2) be impaired in patients with bilateral temporal lobe pathology. Here, we examined whether unilateral temporal lobe dysfunction also impairs the ability to generate future events. ⋯ Patients with temporal lobe epilepsy generate less details when asked to describe past and potential future events, particularly with regard to details involving specific events, places and perceptions. These same patients are aware of their difficulties in this realm, but judge their past memories as similar in vividness and even more personally significant than the memories generated by control participants. The deficits in generation of future episodic details were particularly pronounced in patients with left temporal lobe epilepsy. Verbal semantic fluency was correlated with the ability to generate future scenarios.

Review Meta Analysis
Psychological functioning of people living with chronic pain: a meta-analytic review.
Chronic pain (CP; >3 months) is a common condition that is associated with significant psychological problems. Many people with CP do not fit into discrete diagnostic categories, limiting the applicability of research that is specific to a particular pain diagnosis. This meta-analysis synthesized the large extant literature from a general CP, rather than diagnosis-specific, perspective to systematically identify and compare the psychological problems most commonly associated with CP. ⋯ Positive clinical implications: This is the first time that the CP literature has been synthesized from a general perspective to examine psychological functioning in the presence of CP and provide practical recommendations for assessment and therapy. Individuals with CP were most likely to experience psychological problems in physically focussed areas - namely pain anxiety/concern and somatization. Although fear of pain was intrinsically tied to the CP experience, self-efficacy was not. CP was more strongly associated with anxiety than with depression. Limitations The study focuses on the general CP literature, adults and research-utilizing self-report measures. Meta-analyses are limited by the empirical literature on which they are based.

Multicenter Study
Associations between executive functioning, coping, and psychosocial functioning after acquired brain injury.
To examine the relationships between executive functioning, coping, depressive symptoms, and quality of life in individuals with neuropsychiatric symptoms after acquired brain injury (ABI). ⋯ Coping influences the association between executive functioning and quality of life. Individuals who report difficulties with executive functioning after ABI may be inclined to use passive coping styles, which are maladaptive. Problem-focused coping strategies may be more useful for individuals who have strong executive abilities. This study was a cross-sectional study; thus, a cause-and-effect relationship could not be established between executive functioning, coping, and psychosocial functioning. As this research was part of standard clinical care, non-traditional tests for executive functioning were not administered.

Previous research has identified an association between traumatic experiences and psychotic symptoms. Few studies, however, have explored the underlying mechanisms and contingent nature of these associations in an integrated model. This study aimed to test a moderated mediation model of negative childhood experiences, associated cognitive processes, and psychotic experiences within a context of adolescent loneliness. ⋯ Moderated mediation analyses poses an alternative framework to the understanding of trauma-psychosis associations Adolescent loneliness is a vulnerability factor within this association Data are based on a Northern Irish sample with relatively low levels of loneliness Cross-sectional data cannot explore the developmental course of these experiences in adolescence.
