Multicenter Study Comparative Study
Comorbidity of anxiety disorders with anorexia and bulimia nervosa.
A large and well-characterized sample of individuals with anorexia nervosa and bulimia nervosa from the Price Foundation collaborative genetics study was used to determine the frequency of anxiety disorders and to understand how anxiety disorders are related to state of eating disorder illness and age at onset. ⋯ The prevalence of anxiety disorders in general and OCD in particular was much higher in people with anorexia nervosa and bulimia nervosa than in a nonclinical group of women in the community. Anxiety disorders commonly had their onset in childhood before the onset of an eating disorder, supporting the possibility they are a vulnerability factor for developing anorexia nervosa or bulimia nervosa.

The Hamilton Depression Rating Scale: has the gold standard become a lead weight?
The Hamilton Depression Rating Scale has been the gold standard for the assessment of depression for more than 40 years. Criticism of the instrument has been increasing. The authors review studies published since the last major review of this instrument in 1979 that explicitly examine the psychometric properties of the Hamilton depression scale. The authors' goal is to determine whether continued use of the Hamilton depression scale as a measure of treatment outcome is justified. ⋯ Evidence suggests that the Hamilton depression scale is psychometrically and conceptually flawed. The breadth and severity of the problems militate against efforts to revise the current instrument. After more than 40 years, it is time to embrace a new gold standard for assessment of depression.

Many terminally ill patients enroll in a hospice late in their illness, and recent data indicate decreasing lengths of hospice enrollment, yet we know little about the impact of hospice enrollment length on surviving caregivers. This is the first study the authors know of that examines the association between hospice enrollment length and subsequent major depressive disorder among surviving caregivers. ⋯ The findings identify a target group for whom bereavement services might be most needed. The authors also suggest that earlier hospice enrollment may help reduce the risk of major depressive disorder during the first 6-8 months of bereavement, which raises concerns about recent trends toward decreasing lengths of hospice enrollment before death.

Separation from loved ones commonly leads to grief reactions. In some individuals, grief can evolve into a major depressive episode. The brain regions involved in grief have not been specifically studied. The authors studied brain activity in women actively grieving a recent romantic relationship breakup. It was hypothesized that while remembering their ex-partner, subjects would have altered brain activity in regions identified in sadness imaging studies: the cerebellum, anterior temporal cortex, insula, anterior cingulate, and prefrontal cortex. ⋯ During acute grief, subjects showed brain activity changes in the cerebellum, anterior temporal cortex, insula, anterior cingulate, and prefrontal cortex, consistent with the hypothesis. Subjects with greater baseline grief showed greater decreases in all these regions except for the cerebellum. Further imaging studies are needed to understand the relationship between normal sadness, grief, and depression.
