Repeat Coronary Artery Dissection in Pregnancy: A Case Report and Review of the Literature

Non‐atherosclerotic spontaneous coronary artery dissection (NA‐SCAD) is a rare cause of morbidity and mortality with a propensity for young, healthy, and often peripartum women. NA‐SCAD etiology is poorly understood, with possible hormonal and hereditary mechanisms. Current treatment strategies range from conservative management (often showing resolution on angiographic follow‐up) to invasive angiographic procedures. Rarely, NA‐SCAD has recurred in another coronary artery, ranging hours to years later. We report NA‐SCAD of the right coronary artery (RCA) in a 30‐year old, 3‐month postpartum female with an additional autopsy finding of remote myocardial infarction (MI) in the left anterior descending (LAD) coronary artery territory. The remote MI is consistent with prior NA‐SCAD of the LAD and, given the medical history, may have occurred in the peripartum period of the decedent first pregnancy 3 years earlier. As such, to the best of our knowledge, this may represent the first reported case of NA‐SCAD recurrence in a subsequent pregnancy.     

Temporal variation of oxygen isotope ratios (δ18O) in drinking water: implications for specifying location of origin with human scalp hair

Previous work suggests that δ(18)O values of human hair can be used to constrain the region-of-origin of unknown individuals, but robust assessments of uncertainties in this method are lacking. Here we assess one source of uncertainty - temporal variation in the δ(18)O value of drinking water - using a monthly tap water survey of δ(18)O to develop geospatial models (i.e., maps) of the intra-annual variation (seasonality) in tap water δ(18)O for the contiguous USA. Temporal variation in tap water δ(18)O was correlated with water-supply type, and was related to geographic patterns of precipitation δ(18)O seasonality and water residence time. The maps were applied in a Bayesian framework to identify the geographic origin of an unidentified woman found in Utah, based on measured δ(18)O of scalp hair. The results are robust in specifying parts of the western USA as the most likely region-of-origin. Incorporation of tap water δ(18)O seasonality in the analysis reduces the precision of geographic assignments, but other sources of uncertainty (e.g., spatial interpolation uncertainty) have an equal or larger effect.     

Report on the analysis of common beverages spiked with gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL) using NMR and the PURGE solvent-suppression technique

In forensic evidence, the identification and quantitation of gamma-hydroxybutyric acid (GHB) in "spiked" beverages is challenging. In this report, we present the analysis of common alcoholic beverages found in clubs and bars spiked with gamma-hydroxybutyric acid (GHB) and gamma-butyrolactone (GBL). Our analysis of the spiked beverages consisted of using (1)H NMR with a water suppression method called Presaturation Utilizing Relaxation Gradients and Echoes (PURGE). The following beverages were analyzed: water, 10% ethanol in water, vodka-cranberry juice, rum and coke, gin and tonic, whisky and diet coke, white wine, red wine, and beer. The PURGE method allowed for the direct identification and quantitation of both compounds in all beverages except red and white wine where small interferences prevented accurate quantitation. The NMR method presented in this paper utilizes PURGE water suppression. Thanks to the use of a capillary internal standard, the method is fast, non-destructive, sensitive and requires no sample preparation which could disrupt the equilibrium between GHB and GBL.     

Female Perpetrated Dyadic Psychological Aggression Predicts Relapse in a Treatment Sample of Men with Substance Use Disorders

This study examined whether female-to-male (FTM) psychological aggression predicted men’s relapse of substance use disorder (SUD) 6 months following substance use treatment. Men diagnosed with either a substance abuse or dependence disorder who had recently begun an SUD treatment program participated in the study with their female relationship partners (N = 173). Logistic regression was used to examine the relationship between baseline FTM psychological aggression and SUD relapse when controlling for baseline demographic, dyadic, substance abuse- and treatment-related variables, as well as frequencies of other male- and female-perpetrated aggressive dyadic behaviors. Higher frequencies of severe, but not minor, forms of FTM psychological aggression uniquely predicted an increased risk of relapse at 6 months follow-up. These data add to the developing research program highlighting the negative sequelae of female-perpetrated psychological aggression and also provide an empirical basis for targeting specific dyadic behaviors in the context of SUD treatment and relapse prevention.     

Maintaining change programmes for offenders: some suggestions for practice

Abstract

Despite the widespread acceptance that follow-up or maintenance sessions are an important part of the change process for those who have completed offender rehabilitation programmes, there have been few attempts to articulate the basis upon which such sessions might be developed. This paper reviews the current theoretical and empirical literature relating to maintenance programmes, concluding that whilst there are a number of theories which might be relevant to the design of effective maintenance programmes, there is almost no empirical basis from which to make any assessment of their likely value or effectiveness.     

The Dating Preferences of Liberals and Conservatives

American politics has become more polarized. The source of the phenomena is debated. We posit that human mate choice may play a role in the process. Spouses are highly correlated in their political preferences, and research in behavioral genetics, neuroscience, and endocrinology shows that political preferences develop through a complex interaction of social upbringing, life experience, immediate circumstance, and genes and hormones, operating through one’s psychological architecture by Hatemi et al. (J Theor Politics, 24:305–327, 2012). Consequently, if people with similar political values produce children, there will be more individuals at the ideological extremes over generations. This said, we are left with a mystery: spousal concordance on political attitudes does not result from convergence over the course of the relationship, nor are spouses initially selecting one another on political preferences. We examine whether positive mate assortation—like seeks like—on non-political factors such as lifestyle and demographics could lead to inadvertent assortation on political preferences. Using a sample of Internet dating profiles we find that both liberals and conservatives seek to date individuals who are like themselves. This result suggests a pathway by which long-term couples come to share political preferences, which in turn could be fueling the widening ideological gap in the United States.     

Posttraumatic Stress Disorder Symptoms,Relationship Adjustment,and Relationship Aggression in a Sample of Female Flood Victims

This study tested a model examining the interrelationships among posttraumatic stress disorder (PTSD) symptoms, intimate relationship adjustment, and intimate relationship aggression in a sample of 205 adult female flood victims. At the bivariate level, higher PTSD symptoms were associated with higher physical and psychological aggression victimization, poorer relationship adjustment, and higher physical and psychological aggression perpetration. Results from structural equation modeling (SEM) analyses indicated that relationship aggression victimization influenced aggression perpetration directly, and in the case of physical aggression, indirectly through its relationship with PTSD symptoms and relationship adjustment. The influence of PTSD symptoms on physical aggression perpetration was fully explained by poorer relationship adjustment. These findings extend prior work from other traumatized populations documenting associations between variables reflecting PTSD symptomatology and indices of relationship functioning, and indicate a need for further investigation in this area of inquiry. This research was supported in part by a grant to Patricia A. Resick from the National Institute of Mental Health (1-R01-MH55542).     

Symptoms of trauma, perceptions of discrimination, and anger: a comparison between Australian indigenous and nonindigenous prisoners

Although the need for the development and provision of culturally appropriate rehabilitation programs for offenders is widely acknowledged, there is a lack of empirical data that can be used as a basis for the development of new programs. This article reports the findings of a comparison of indigenous and nonindigenous male prisoners on a range of measures relevant to the experience of anger by indigenous prisoners in Australia. The results suggest that indigenous participants are more likely to experience symptoms of early trauma, have greater difficulties identifying and describing feelings, and perceive higher levels of discrimination than nonindigenous prisoners. The implications of this work for the development of culturally appropriate and effective anger management programs for indigenous male prisoners are discussed.     

Therapeutic mechanisms of suicidal ideation: the influence of changes in automatic thoughts and immature defenses

The treatment processes associated with reduced suicidal ideation have received little research attention. This study evaluates the influence on suicidal ideation of theory-based intrapsychic processes: maladaptive cognition and defensive style. Thirty-three community mental health patients completed questionnaires at two time points. Decreases in automatic thoughts were a strong correlate of decreased suicidal ideation, and decreases in immature defenses were a moderate strength correlate. These relationships remained significant even when controlling for initial level of depression. The theorized mechanisms of cognitive-behavioral and psychodynamic therapy had the expected effects on suicidal ideation. The strong association of decreased maladaptive cognitions with decreased suicidal ideation supports further development of cognitive-behavioral suicide interventions and clinical use of cognitive interventions. Psychodynamic processes in suicidal ideation and behavior warrant further exploration.     

Peer Selection and Socialization in Adolescent Depression: The Role of School Transitions

Previous studies have indicated homophily in depressive symptoms among adolescent friends, resulting from both peer selection and socialization processes. However, developmental differences and the role of school transitions in these processes have not been elucidated. A sample of 367 (51% female) adolescents was followed from 6th to 11th grade to investigate prospective relationships between adolescents’ and their friends’ depressive symptoms in middle school and in high school. Results revealed that students selected friends with similar levels of depressive symptoms after each school transition. Additionally, friends appeared to socialize adolescents to become more similar in depressive affect in late middle school years. These findings suggest normative selection effects after school transitions, followed by socialization effects in middle school, but not high school.
