Longitudinal PTSD symptom trajectories: Relative contributions of state anxiety, depression, and emotion dysregulation.

Background: Prospective research on the development and trajectory of PTSD symptoms after a traumatic event is crucial for assessment and early intervention. Further, examining predictors of PTSD pathology provides a better conceptualization of the temporal course of PTSD in trauma victims.

Methods: The present study examined PTSD symptom severity in individuals presenting to the emergency department (ED) following a traumatic event.

A Naturalistic Study of Outcomes for Durable Remission in Patients With Bipolar Disorder.

Objective: Bipolar disorder is a severe mental illness affecting emotional stability, physical health, and quality of life. In a previous study, we identified medications associated with remission in patients with bipolar disorder. The objective of the current study was to determine the status of the patients after 3 additional years, as well as the medications associated with remission.

Emotion Dysregulation Prospectively Predicts Posttraumatic Stress Disorder Symptom Severity 3 Months After Trauma Exposure.

Despite growing evidence in support of emotion dysregulation as a risk factor for the development of posttraumatic stress disorder (PTSD) following trauma exposure, few studies have examined temporal relations between emotion dysregulation and the onset and/or worsening of PTSD symptoms over time. The aim of the present study was to extend research on temporal associations between emotion dysregulation and PTSD in a sample of individuals recruited from hospital emergency departments soon after a traumatic event. Adult participants (N = 85; 62.

A Descriptive Analysis of Factors Leading to a 1-Year Remission in Bipolar Disorder.

Background: Bipolar spectrum disorders are associated with symptomatic and functional disability in many patients. Other studies have examined predictors of outcome with variable results. The goal of this retrospective study was to identify medications associated with a minimum of 12 consecutive months of symptomatic, functional, and syndromal remission.

Hypertriglyceridemia-Induced Pancreatitis in Psychiatric Patients: A Case Report and Review of Literature.

Hypertriglyceridemia is a known cause of 2%-7% of cases of acute pancreatitis. Although there are numerous potential causes, the use of atypical antipsychotics has been linked to elevated triglycerides and pancreatitis. Here, we present the case of a 42-year-old male patient with a diagnosis of schizoaffective disorder who presented to our hospital with acute pancreatitis due to hypertriglyceridemia, which was exacerbated after he was started on quetiapine.

Comparing treatment outcomes of bipolar patients between psychiatry residents and attending physicians.

Objective: The authors sought to compare the outcomes of patients treated by psychiatric residents and attending psychiatrists.

Method: Charts of 121 outpatients meeting criteria for bipolar spectrum disorder were analyzed. Residents treated 41, and attending physicians 80, of 121 patients.

Eco-cultural health, global health, and sustainability.

Anthropogenic stress on the earth's ecosystems has resulted in widespread prevalence of ecosystem distress syndrome, a quantifiable set of signs of ecosystem degradation. At the same time, the planet is witnessing rapid declines in global cultural diversity and in the vitality of the world's cultures, which closely mirror, and are interrelated with, ecological degradation. As a consequence of this converging crisis of loss of ecosystem and cultural health, global health and sustainability are increasingly under threat.

Time for an ecosystem approach to public health? Lessons from two infectious disease outbreaks in Canada.

Ecosystem approaches recognize the complexity of many contemporary public health challenges and offer an alternative for dealing with problems that have proven intractable and unresponsive to conventional public health strategies. Infectious disease outbreaks are among the most dramatic aspects of systems failure, and the Canadian cases of SARS (Severe Acute Respiratory Syndrome) in Toronto, and the E. coli outbreak in Walkerton, serve as useful illustrative examples.

Effectiveness of adjunctive antidepressant treatment for bipolar depression.

Background: Episodes of depression are the most frequent cause of disability among patients with bipolar disorder. The effectiveness and safety of standard antidepressant agents for depressive episodes associated with bipolar disorder (bipolar depression) have not been well studied. Our study was designed to determine whether adjunctive antidepressant therapy reduces symptoms of bipolar depression without increasing the risk of mania.

Sustainability science: an ecohealth perspective.

Sustainability science is emerging as a transdisciplinary effort to come to grips with the much-needed symbiosis between human activity and the environment. While there is recognition that conventional economic growth must yield to policies that foster sustainable development, this has not yet occurred on any broad scale. Rather, there is clear evidence that the Earth's ecosystems and landscapes continue to degrade as a consequence of the cumulative impact of human activities.

A 20-month, double-blind, maintenance trial of lithium versus divalproex in rapid-cycling bipolar disorder.

Objective: The authors tested the hypothesis that divalproex would be more effective than lithium in the long-term management of patients with recently stabilized rapid-cycling bipolar disorder.

Method: A 20-month, double-blind, parallel-group comparison was carried out in recently hypomanic/manic patients who had experienced a persistent bimodal response to combined treatment with lithium and divalproex. Sixty patients were randomly assigned to lithium or divalproex monotherapy in a balanced design after stratification for illness type (bipolar I versus bipolar II disorder).

Gender differences in criminality: bipolar disorder with co-occurring substance abuse.

Outpatient interviews to collect criminal history data were conducted with 55 women and 77 men who had the dual diagnosis of rapid-cycling bipolar disorder with co-morbid substance abuse disorders (DD-RCBD), to ascertain gender-related similarities and differences. Fifty-three percent of women and 79 percent of men reported that they had been charged with a crime, and nearly half of those charged had been incarcerated. Men with DD-RCBD were more likely to have committed a felony and had a trend of committing more misdemeanors.

New data on the use of lithium, divalproate, and lamotrigine in rapid cycling bipolar disorder.

The rapid cycling variant of bipolar disorder is defined as the occurrence of four periods of either manic or depressive illness within 12 months. Patients suffering from this variant of bipolar disorder have an unmet need for effective treatment. This review examines two major studies in an attempt to update understanding of the current therapies available to treat rapid cycling patients.

Linking health and ecology in the medical curriculum.

Human health vulnerabilities to ecosystem degradation are well documented. Destabilization of natural ecosystems and the biosphere have posed an entirely new set of risks to human health and preclude any simple extrapolations from the past. Newly emerging diseases, increasing prevalence of many vector borne diseases, increased exposure to harmful UV radiation and a number of other transformations in the natural environment, have decidedly negative implications for the sustainability of human health.

Bipolar disorders and the effectiveness of novel anticonvulsants.

The discovery that valproic acid is helpful in the management of patients with rapid-cycling bipolar disorder led to an explosion of research culminating in the third-generation anticonvulsants. Refractory depressive phases are frequent in bipolar disorders. No studies to date have shown that gabapentin is effective in bipolar mania or hypomania.

Current research on rapid cycling bipolar disorder and its treatment.

Rapid cycling is a pattern of presentation of bipolar disorder that specifies the course of the illness and is associated with a greater morbidity. The validity of rapid cycling as a distinct course modifier for bipolar disorder has been demonstrated and the term has been incorporated into the DSM-IV. The phenomenon of rapid cycling tends to appear late in the course of the disorder, occurs more frequently among females, and is more frequently seen in patients with bipolar type II disorder.

Bipolar rapid cycling: focus on depression as its hallmark.

The phenomenon of frequent cycling in bipolar disorder was first recognized by Emil Kraepelin in 1913. More recently, rapid cycling has been reported to be a predictor of nonresponse to treatment. At the time of presentation, most patients with DSM-IV-defined rapid cycling appear to be in the depressed phase of their illness.

Evolving methodologies in bipolar disorder maintenance research.

Background: During the development of a new treatment for bipolar disorder, maintenance studies are used to evaluate the ability of the putative mood stabilizer to prevent relapse and recurrence of further episodes. Comparisons with the early bipolar disorder maintenance studies indicate that the methodologies of recent trials have evolved substantially.

Aims: To review the methods used in the first- and second-generation maintenance studies, highlighting the differences of the various designs.
