Depression Alone (depression + alone)
Selected AbstractsThe impact of panic-agoraphobic comorbidity on suicidality in hospitalized patients with major depressionDEPRESSION AND ANXIETY, Issue 3 2010Lily A. Brown B.S. Abstract Background: Previous research in outpatient samples suggests that panic and agoraphobic comorbidity is related to suicidality in outpatients with major depression. The purpose of the study was to further investigate this relationship specifically in a hospitalized sample. Method: This study examined the severity of current suicidal ideation and behaviors in a psychiatric hospital sample diagnosed with major depressive disorder alone (MDD; n=28) versus MDD plus panic-agoraphobic spectrum disorders (MDD+PAS; n=69). Results: Members of the MDD+PAS group were significantly more likely to have had a suicide attempt history, higher current depression severity, and higher current suicidal severity compared with individuals in the MDD alone group. The relationship between the current suicidality and comorbid PAS remained significant after controlling for the overall depression severity and other clinical factors. Conclusions: These findings suggest that panic-agoraphobic comorbidity is associated with a greater risk for suicidality in hospitalized patients, which cannot be adequately explained by the level of current depression alone. The clinical and research implications for these findings are discussed. Depression and Anxiety, 2010. © 2010 Wiley-Liss, Inc. [source] Pregnancy complications associated with childhood anxiety disordersDEPRESSION AND ANXIETY, Issue 3 2004Dina R. Hirshfeld-Becker Ph.D. Abstract To determine whether perinatal complications predict childhood anxiety disorders independently of parental psychopathology, we systematically assessed pregnancy and delivery complications and psychopathology in a sample of children (mean age=6.8 years) at high risk for anxiety disorders whose parents had panic disorder with (n=138) or without (n=26) major depression, and in contrast groups of offspring of parents with major depression alone (n=47), or no mood or anxiety disorders (n=95; total N=306). Psychopathology in the children was assessed by structured diagnostic interviews (K-SADS), and pregnancy and delivery complications were assessed using the developmental history module of the DICA-P. Number of pregnancy complications predicted multiple childhood anxiety disorders independently of parental diagnosis (odds ratio=1.6 [1.4,2.0]). This effect was accounted for by heavy bleeding requiring bed-rest, hypertension, illness requiring medical attention, and serious family problems. Associations remained significant when lifetime child mood and disruptive behavior disorders were covaried. Results suggest that prenatal stressors may increase a child's risk for anxiety disorders beyond the risk conferred by parental psychopathology alone.

[source] Platelet activation and secretion in patients with major depression, thoracic aortic atherosclerosis, or renal dialysis treatmentDEPRESSION AND ANXIETY, Issue 3 2002Dominique L. Musselman M.D., M.S. Abstract Relatively little is known concerning the magnitude of alterations of platelet activation and secretion markers of patients with major depression when compared to patients at increased risk for, or with current, clinically significant atherosclerosis. Markers of in vivo platelet stimulation and secretion were measured under basal conditions in normal comparison subjects (n = 12) and three patient groups: patients diagnosed with DSM-IV major depression (n = 15), dialysis-dependent patients (n = 12), and patients with severe thoracic aortic atherosclerosis (n = 10). In comparison to normal comparison subjects, depressed patients and patients with thoracic aortic atherosclerosis exhibited the greatest platelet stimulation as detected by increased anti-LIBS platelet binding. Dialysis-dependent patients exhibited the highest plasma concentrations of the renally-excreted platelet-specific secretion protein, ,-thromboglobulin. This study extends previous observations of increased platelet activation in patients with major depression and documents similar alterations in patients with transesophageal echocardiography (TEE)-documented thoracic aortic atherosclerosis. Future studies will determine whether the magnitude of platelet stimulation and secretion in patients with comorbid depression and atherosclerotic aortic disease is greater than that observed in nondepressed patients with atherosclerotic aortic disease or major depression alone. These findings provide further evidence for either increased platelet activation and/or intrinsic heightened platelet reactivity as one of the biological substrates underlying the increased risk of depressed patients for cardiovascular disease.

[source] Major depression, chronic minor depression, and the five-factor model of personalityEUROPEAN JOURNAL OF PERSONALITY, Issue 4 2002Kate L. Harkness Fifty-eight outpatients with major depression completed the NEO Personality Inventory at intake (time 1) and after up to three months of anti-depressant treatment (time 2). Within this group, 26 patients met additional Research Diagnostic Criteria for chronic minor depression. Repeated-measures analyses revealed significant decreases in Neuroticism scores, and significant increases in Extraversion and Conscientiousness scores, from time 1 to time 2 for both patient groups. In addition, despite similar symptom severity at time 2, the patients with major depression+chronic minor depression scored significantly higher on the Angry Hostility facet of Neuroticism and significantly lower on Agreeableness than those with major depression alone. We suggest from these findings that Angry Hostility and low Agreeableness may represent a trait vulnerability in individuals with chronic minor depression that persists even following remission of the major depressive state, and that this may help to explain their high rates of relapse and recurrence.

[source] MAINTENANCE OF ANDRODIOECY IN THE FRESHWATER SHRIMP, EULIMNADIA TEXANA: ESTIMATES OF INBREEDING DEPRESSION IN TWO POPULATIONSEVOLUTION, Issue 3 2000Stephen C. Weeks Abstract., Androdioecy is an uncommon form of reproduction in which males coexist with hermaphrodites. Androdioecy is thought to be difficult to evolve in species that regularly inbreed. The freshwater shrimp Eulimnadia texana has recently been described as both androdioecious and highly selfing and is thus anomalous. Inbreeding depression is one factor that may maintain males in these populations. Here we examine the extent of "late" inbreeding depression (after sexual maturity) in these clam shrimp using two tests: (1) comparing the fitness of shrimp varying in their levels of individual heterozygosity from two natural populations that differ in overall genetic diversity; and (2) specifically outcrossing and selfing shrimp from these same populations and comparing fitness of the resulting offspring. The effects of inbreeding differed within each population. In the more genetically diverse population, fecundity, size, and mortality were significantly reduced in inbred shrimp. In the less genetically diverse population, none of the fitness measures was significantly lowered in selfed shrimp. Combining estimates of early inbreeding depression from a previous study with current estimates of late inbreeding depression suggests that inbreeding depression is substantial (,= 0.68) in the more diverse population and somewhat lower (,= 0.50) in the less diverse population. However, given that males have higher mortality rates than hermaphrodites, neither estimate of inbreeding depression is large enough to account for the maintenance of males in either population by inbreeding depression alone. Thus, the stability of androdioecy in this system is likely only if hermaphrodites are unable to self-fertilize many of their own eggs when not mated to a male or if male mating success is generally high (or at least high when males are rare). Patterns of fitness responses in the two populations were consistent with the hypothesis that inbreeding depression is caused by partially recessive deleterious alleles, although a formal test of this hypothesis still needs to be conducted.

Givens MD OBJECTIVES: To measure the prevalence, predictors, and posthospitalization outcomes associated with the overlap syndrome of coexisting depression and incident delirium in older hospitalized patients. DESIGN: Secondary analysis of prospective cohort data from the control group of the Delirium Prevention Trial. SETTING: General medical service of an academic medical center. Follow-up interviews at 1 month and 1 year post-hospital discharge. PARTICIPANTS: Four hundred fifty-nine patients aged 70 and older who were not delirious at hospital admission. MEASUREMENTS: Depressive symptoms assessed at hospital admission using the 15-item Geriatric Depression Scale (cutoff score of 6 used to define depression), daily assessments of incident delirium from admission to discharge using the Confusion Assessment Method, activities of daily living at admission and 1 month postdischarge, and new nursing home placement and mortality determined at 1 year. RESULTS: Of 459 participants, 23 (5.0%) had the overlap syndrome, 39 (8.5%) delirium alone, 121 (26.3%) depression alone, and 276 (60.1%) neither condition. In adjusted analysis, patients with the overlap syndrome had higher odds of new nursing home placement or death at 1 year (adjusted odds ratio (AOR)=5.38, 95% confidence interval (CI)=1.57,18.38) and 1-month functional decline (AOR=3.30, 95% CI=1.14,9.56) than patients with neither condition. CONCLUSION: The overlap syndrome of depression and delirium is associated with significant risk of functional decline, institutionalization, and death. Efforts to identify, prevent, and treat this condition may reduce the risk of adverse outcomes in older hospitalized patients. [source] Impact of PTSD comorbidity on one-year outcomes in a depression trialJOURNAL OF CLINICAL PSYCHOLOGY, Issue 7 2006Bonnie L. Green Low-income African American, Latino, and White women were screened and recruited for a depression treatment trial in social service and family planning settings. Those meeting full criteria for major depression (MDD; N = 267) were randomized to cognitive,behavior therapy (CBT), antidepressant medication, or community mental health referral. All randomly assigned participants were evaluated by baseline telephone and clinical interview, and followed by telephone for one year. Posttraumatic stress disorder (PTSD) comorbidity was assessed at baseline and one-year follow-up in a clinical interview. At baseline, 33% of the depressed women had current comorbid PTSD. These participants had more exposure to assaultive violence, had higher levels of depression and anxiety, and were more functionally impaired than women with depression alone. Depression in both groups improved over the course of one year, but the PTSD subgroup remained more impaired throughout the one-year follow-up period. Thus, evidence-based treatments (antidepressant medication or structured psychotherapy) decrease depression regardless of PTSD comorbidity, but women with PTSD were more distressed and impaired throughout. Including direct treatment of PTSD associated with interpersonal violence may be more effective in alleviating depression in those with both diagnoses. © 2006 Wiley Periodicals, Inc.
