Mesiotemporal Volume Loss Associated with Disorder Severity: A VBM Study in Borderline Personality Disorder
<div><p>Results of MRI volumetry in Borderline Personality Disorder (BPD) are inconsistent. Some, but not all, studies reported decreased hippocampus, amygdala, and/or prefrontal volumes. In the current study, we used rater-independent voxel-based morphometry (VBM) in 33 female BPD patients and 33 healthy women. We measured gray matter (GM) volumes of the whole brain and of three volumes of interest (VOI), i.e., the hippocampus/parahippocampal gyrus, the amygdala and the anterior cingulate gyrus (ACC). Analyses were conducted using lifetime diagnoses of posttraumatic stress disorder (PTSD) and major depression (MD) as covariates. We used adversive childhood experiences and the numbers of BPD criteria (as an indicator of disorder severity) to investigate associations with GM volumes. We did not find volume differences between BPD patients and healthy subject, neither of the whole brain nor of the three VOIs, independent of presence or absence of comorbid PTSD and MD. We also did not find a relationship between childhood maltreatment and the patients’ brain volumes. However, within the patient group, the number of BPD criteria fulfilled was inversely correlated with left hippocampal/parahippocampal volume (x=-32, y=-23, z=-18, k=496, t=5.08, p=.007). Consequently, mesiotemporal GM volumes do not seem to differentiate patients from healthy subjects, but might be associated with symptom severity within the BPD group.</p> </div
Physical and Social Pains in Borderline Disorder and Neuroanatomical Correlates: A Systematic Review
A high-latitude coral community with an uncertain future: Stetson Bank, northwestern Gulf of Mexico
Limited data exist that detail trends in benthic community composition of high-latitude coral communities. As anthropogenic stressors are projected to increase in number and intensity, long-term monitoring datasets are essential to understanding community stability and ecosystem resilience. In 1993, a long-term monitoring program was initiated at Stetson Bank, in the Gulf of Mexico. Over the course of this monitoring, a major shift in community structure occurred, in which the coral-sponge community was replaced by an algal-dominated community. During the initial years of this study, the coral community at Stetson Bank was relatively stable. Beginning in the late 1990s, sponge cover began a steady decline from over 30 % to less than 25 %. Then, in 2005, the benthic community underwent a further significant change when living coral cover declined from 30 % to less than 8 % and sponges declined to less than 20 % benthic cover. This abrupt shift corresponded with a Caribbean-wide bleaching event in 2005 that caused major mortality of Stetson Bank corals. Previous bleaching events at Stetson Bank did not result in wide-scale coral mortality. Several environmental parameters may have contributed to the rapid decline in this benthic community. We suggest that the combined effects of coastal runoff and elevated temperatures contributed to the observed shift. We present an analysis of 15 years of monitoring data spanning from 1993 to 2008; this dataset provides both a biological baseline and a multiyear trend analysis of the community structure for a high-latitude coral-sponge community in the face of changing climatic conditions
Self-reported impulsivity in women with borderline personality disorder: the role of childhood maltreatment severity and emotion regulation difficulties
The Relationship between Non-Suicidal Self-Injury and the UPPS-P Impulsivity Facets in Eating Disorders and Healthy Controls
In the present study, we investigated the association between Non-Suicidal Self-Injury (NSSI) and the UPPS-P impulsivity facets in eating disorder patients and healthy controls. The prevalence of NSSI in eating disorder (ED) patients ranged from 17% in restrictive anorexia nervosa (AN-R) patients to 43% in patients with bulimia nervosa (BN). In healthy controls (HC), the prevalence of NSSI was 19%. Eating disorder patients from the binge eating/purging type showed significantly more NSSI compared to restrictive ED and HC participants. Binge-eating/purging ED patients also scored significantly higher on Negative/Positive Urgency, Lack of Premeditation and Lack of Perseverance compared to HC and restrictive ED patients. Comparable findings were found between ED patients and HC with and without NSSI; ED patients and HC with NSSI scored significantly higher in four of the five UPPS-P dimensions compared to participants without NSSI; Sensation Seeking was the exception. Finally, the presence of NSSI in HC/ED patients was particularly predicted by low levels of Perseverance. Therefore, the treatment of ED patients with NSSI certainly needs to focus on the training of effortful control
