Background: Non-ST elevation myocardial infarction (NSTEMI) has higher post-discharge mortality than ST-elevation myocardial infarction (STEMI). Prognosis worsens in those with multivessel coronary disease (MVD). However, information about the prevalence and extent of MVD in NSTEMI is limited, in turn limiting insights into optimal treatment strategies.

It is imperative to understand the specific and shared etiologies of major depression and cardio-metabolic disease, as both traits are frequently comorbid and each represents a major burden to society. This study examined whether there is a genetic association between major depression and cardio-metabolic traits and if this association is stratified by age at onset for major depression. Polygenic risk scores analysis and linkage disequilibrium score regression was performed to examine whether differences in shared genetic etiology exist between depression case control status (N cases = 40,940, N controls = 67,532), earlier (N = 15,844), and later onset depression (N = 15,800) with body mass index, coronary artery disease, stroke, and type 2 diabetes in 11 data sets from the Psychiatric Genomics Consortium, Generation Scotland, and UK Biobank.

Background: The prevalence of depression is higher in individuals with autoimmune diseases, but the mechanisms underlying the observed comorbidities are unknown. Shared genetic etiology is a plausible explanation for the overlap, and in this study we tested whether genetic variation in the major histocompatibility complex (MHC), which is associated with risk for autoimmune diseases, is also associated with risk for depression.

Methods: We fine-mapped the classical MHC (chr6: 29.

To understand how cognitive dysfunction contributes to social cognitive deficits in depression, we investigated the relationship between executive function and social cognitive performance in adolescents and young adults during current and remitted depression, compared to healthy controls. Social cognition and executive function were measured in 179 students (61 healthy controls and 118 patients with depression; M = 20.60 years; SD = 3.

Background: Social cognition - the ability to identify, perceive, and interpret socially relevant information - is an important skill that plays a significant role in successful interpersonal functioning. Social cognitive performance is recognized to be impaired in several psychiatric conditions, but the relationship with major depressive disorder is less well understood. The aim of this review is to characterize the current understanding of: (i) the different domains of social cognition and a possible relationship with major depressive disorder, (ii) the clinical presentation of social cognition in acute and remitted depressive states, and (iii) the effect of severity of depression on social cognitive performance.

Objectives: To define the clinical and demographic characteristics of frequent attenders with mental disorders at a general hospital ED; to determine whether those persons had additional attendances at other ED in the same city; and to assess the documented care of those frequent attenders.

Method: A retrospective descriptive study of those who attended the Queen Elizabeth Hospital, Woodville South, Australia ED on average at least once per month between 1 July 2006 and 15 March 2007.

Results: Of 11,594 attenders, 54 (0.

Background: Motor vehicle accident studies thus far have focused primarily on psychiatric consequences and outcomes and medicolegal and treatment aspects, particularly of posttraumatic stress disorder (PTSD). This study aimed to determine the impact of motor vehicle accident-related psychiatric disorders on health and economic costs in quantitative terms.

Method: Of the 3088 victims of motor vehicle accidents who made a claim through the State Insurance Commission, South Australia, between November 27, 1996, and March 23, 1999, 391 responded to the study and were assessed using the 28-item General Health Questionnaire, the PTSD Checklist-Civilian Version, and the Dissociative Experiences Scale.
