The relationship between treatment settings and diagnostic attributions of depression among African Americans

Objective

To explore the relationship between treatment setting characteristics and diagnostic attributions of depression among community-dwelling African Americans.

Methods

Data come from the National Survey of American Life, a nationally representative sample of African Americans and Caribbean Blacks. Major Depression (MD) was assessed using the Composite International Diagnostic Inventory. Participants were categorized into four diagnostic groups: never MD, MD never attributed to physical health problems (i.e., affective depression), MD sometimes attributed to physical health problems (i.e., complicated depression), and MD always attributed to physical health problems (i.e., physical depression). Multinomial regression was used for assessment.

Results

Among 441 participants, 66.4% were classified as affective depression, 17.8% as complicated depression and 15.8% as physical depression. Seeking treatment from a mental health professional was associated with increased likelihood of being in the complicated depression group [adjusted odds ratio (AOR): 5.52; 95% confidence interval (CI): 2.28-13.36]. Seeking treatment from a family doctor was associated with physical depression (AOR: 2.93; 95% CI: 1.18-7.26). Seeking care from three or more different health care providers was associated with complicated depression (AOR: 1.99; 95% CI: 1.17-3.40).

Conclusion

Results suggest that encounters with health care providers influence the diagnostic attribution of depression in a systematic manner.     

Suicidality in temporal lobe epilepsy: measuring the weight of impulsivity and depression

Objective

The aim of the work described here was to measure the role of psychopathological features, specifically impulsivity and depression, in suicidality in patients with temporal lobe epilepsy (TLE).

Methods

Neuropsychiatric evaluation of 66 outpatients with TLE was performed with the following instruments: a structured clinical interview (Mini International Neuropsychiatric Interview Plus), the Barratt Impulsiveness Scale, the Hamilton Anxiety Scale, the Beck Depression Inventory, and the Brief Psychiatric Rating Scale.

Results

A current Axis I psychiatric diagnosis, mainly mood and anxiety disorders, was assigned to 37 subjects (56.1%) Presence of suicide risk was identified in 19 patients (28.8%), and 14 (21.2%) had attempted suicide. Frequency of seizures (P = 0.012), current major depression (P = 0.001), and motor impulsivity (P = 0.005) were associated with suicide risk on univariate analysis. Logistic regression stressed the main relevance of major depression (OR = 12.82, 95% CI = 2.58-63.76, P = 0.002) and motor impulsivity (OR = 1.21, 95% CI = 1.06-1.38, P = 0.005) to suicide risk.

Conclusion

Depression has a major influence on suicidality in epilepsy. Motor impulsivity is also relevant and may be an important component of depression in TLE associated with suicide risk.     

A serotonin transporter gene polymorphism predicts peripartum depressive symptoms in an at-risk psychiatric cohort

Backgroud

Peripartum major depressive disorder (MDD) is a prevalent psychiatric disorder with potential detrimental consequences for both mother and child. Despite its enormous health care relevance, data regarding genetic predictors of peripartum depression are sparse. The aim of this study was to investigate associations of the serotonin-transporter linked polymorphic region (5-HTTLPR) genotype with peripartum MDD in an at-risk population.

Methods

Two hundred and seventy four women with a prior history of MDD were genotyped for 5-HTTLPR and serially evaluated in late pregnancy (gestational weeks 31-40), early post-partum (week 1-8) and late post-partum (week 9-24) for diagnosis of a current major depressive episode (MDE) and depressive symptom severity.

Results

5-HTTLPR S-allele carrier status predicted the occurrence of a MDE in the early post-partum period only (OR = 5.13, p = 0.017). This association persisted despite continued antidepressant treatment.

Conclusions

The 5-HTTLPR genotype may be a clinically relevant predictor of early post-partum depression in an at-risk population.

Objective

Peripartum major depressive disorder is a prevalent psychiatric disorder with potential detrimental consequences for both mother and child. Despite its enormous health care relevance, data regarding genetic predictors of peripartum depression are sparse. The aim of this study was to investigate associations of the serotonin-transporter linked polymorphic region (5-HTTLPR) genotype with peripartum MDD in an at-risk population.     

New allele-specific real-time PCR system for warfarin dose genotyping equipped with an automatic interpretative function that allows rapid, accurate, and user-friendly reporting in clinical laboratories

Introduction

The optimal dose of the oral anticoagulant warfarin varies with polymorphisms of the vitamin K epoxide reductase complex subunit 1 (VKORC1) and cytochrome P450 2C9 (CYP2C9) genes. A fast and reliable method of warfarin dose adjustment is required to prevent serious hemorrhagic or thrombotic complications. The aim of this study is to develop and validate a new warfarin dose genotyping system with an automatic interpretation function.

Materials and methods

Four VKORC1 and two CYP2C9 SNPs were genotyped by real-time PCR using allele-specific primers and probes. Multiple reactions that included internal positive controls were performed in each well, and an automatic interpretative algorithm was developed. This system was validated using 82 clinical specimens previously genotyped by PCR-direct sequencing. The analytical time of the method was calculated.

Results

No interference was observed when multiple samples were included in each reaction, with all internal positive control reactions being successful. In the genotyping algorithm, Ct differences < 2 and ≥ 2 identified heterozygotes and homozygotes, respectively. All results obtained were concordant with those of the reference method. The overall analytical time for assay of 12 specimens was around 3 hours.

Conclusion

This rapid, accurate, and user-friendly genotyping system improves the efficacy and safety of anticoagulation therapy in clinical practice.     

Racial and ethnic differences in diabetes mellitus among people with and without psychiatric disorders: results from the National Epidemiologic Survey on Alcohol and Related Conditions

Objective

This study examined racial/ethnic differences in the prevalence of diabetes mellitus in a nationally representative sample of adults with and without common psychiatric disorders.

Method

Data were drawn from Wave 2 of the National Epidemiologic Survey on Alcohol and Related Conditions (N=34,653). Logistic regression models adjusting for sociodemographic variables and diabetes risk factors were used to examine racial/ethnic differences in 12-month prevalence rates of diabetes by psychiatric status.

Results

Among people without psychiatric disorders, African Americans, Hispanics and American Indians/Alaska Natives, but not Asians/Pacific Islanders, had significantly higher rates of diabetes than non-Hispanic whites even after adjusting for sociodemographic variables and diabetes risk factors. In the presence of psychiatric disorders, these health disparities persisted for African Americans and Hispanics, but not for American Indians/Alaska Natives. No significant interactions between race/ethnicity and psychiatric disorders in the odds of diabetes were found across any group.

Conclusion

Policies and services that support culturally appropriate prevention and treatment strategies are needed to reduce racial/ethnic disparities in diabetes among people with and without psychiatric disabilities.     

Posttraumatic stress symptoms and postpartum depression in couples after childbirth: the role of partner support and attachment

Aim

The roles of partner attachment and perceptions of partner support were explored in relation to symptoms of posttraumatic stress and postpartum depression in couples within the first three postnatal months.

Methods

Participants (n = 372) were recruited within the first seven days postpartum, and completed questionnaire measures of trait anxiety, symptoms of acute posttraumatic stress, and perceptions of partner support. Postal questionnaires were completed at six weeks and three months, assessing attachment, perception of partner support, symptoms of posttraumatic stress, and postpartum depression. Two hundred and twelve couples completed all time-points.

Results

Results indicated that symptoms were significantly related within couples. Men's acute trauma symptoms predicted their partner's subsequent symptoms of posttraumatic stress. Less secure attachment and dissatisfaction with partner support were associated with higher levels of postpartum depression and posttraumatic stress.

Conclusions

Men's and women's responses following childbirth appear to be strongly interlinked; services should target both members of the dyad.     

Posttraumatic stress disorder is a risk factor for metabolic syndrome in an impoverished urban population

Objective

Metabolic syndrome is associated with elevated risk for cardiovascular disease and diabetes and has increased prevalence in low-income African Americans, which constitutes a significant health disparity. The mechanisms responsible for this disparity remain unclear; the current study investigated the relationship between posttraumatic stress disorder (PTSD) and metabolic syndrome.

Method

We assessed childhood and adult trauma history, major depressive disorder, PTSD and the components of metabolic syndrome in an urban population. We recruited 245 low-socioeconomic-status, primarily African American subjects from general medical clinics in an inner-city hospital.

Results

Trauma exposure was extremely prevalent, with 90.6% of subjects reporting at least one significant trauma and 18.8% of subjects meeting criteria for current PTSD. Metabolic syndrome was also prevalent in this population (33.2%), with significantly higher rates among patients with current PTSD (47.8%, P<.05). After controlling for demographics, smoking history, antipsychotic use, depression and exercise, current PTSD remained the only significant predictor of metabolic syndrome (P=.006).

Conclusions

PTSD is associated with increased rates of metabolic syndrome within a traumatized, impoverished urban population. Further studies should investigate if PTSD treatment may reduce the rates of metabolic syndrome, improve overall health outcomes and decrease health care disparities in minority populations.     

History of depressive episodes as a risk factor for illness severity in early inflammatory arthritis

Objective

Psychosocial research in arthritis consistently demonstrates a relationship between depression and disease characteristics such as severity of illness and physical disability. In this study, we examine how a history of clinical depression identified through diagnostic interviews influences disease outcome measures in patients with early inflammatory arthritis (EIA) in the absence of current depression.

Methods

Patients in the early phase (more than 6-weeks, less than 1-year duration) of inflammatory arthritis were recruited from a larger EIA registry, which recorded sociodemographic data, current depressive symptoms and measures of disease severity. Current and history of major depression was assessed by a structured clinical interview. Eighty-one patients without current major depression were divided into two groups: 28 with and 53 without a history of depression.

Results

There were no significant differences between the two groups in age, sex, education, income, or level of current depressive symptoms. Compared with patients with no history of major depression, those with a history of depressive episodes had higher self-ratings of disease activity and were assessed as having more severe disease and poorer physical functioning by their physicians.

Conclusion

This study indicates that a history of major depression represents a risk factor for disease severity in EIA. This may reflect an enduring physiological effect of depression that influences subsequent inflammatory arthritis or an underlying shared process between these two disease entities.     

The prevalence of dental anxiety across previous distressing experiences

Aims

To compare the prevalence of high dental anxiety across a variety of past distressing experiences with a previously reported Dutch sample.

Method

University students from the UK (N = 1024) completed an online survey containing; the Modified Dental Anxiety Scale, and the Level of Exposure-Dental Experiences Questionnaire (LOE-DEQ). Adjusted odds ratios (OR) were calculated to assess the association of self-reported distressing experiences and dental anxiety.

Results

The percentage of respondents with high dental anxiety (HDA) (total MDAS score ≥ 19) was 11.2%. Significant prevalence of HDA across several distressing experiences was shown in both UK and Dutch samples notably: extreme helplessness during dental treatment, lack of understanding of the dentist and extreme embarrassment during dental treatment. There were little or no effects of non-dental trauma, with the exception of sexual abuse in the UK sample.

Conclusions

Trauma from various past experiences may be implicated in an increased risk of high dental anxiety.     

The brain-derived neurotrophic factor (BDNF) polymorphism Val66Met is associated with neither serum BDNF level nor response to selective serotonin reuptake inhibitors in depressed Japanese patients

Background

We investigated the relationship between a brain-derived neurotrophic factor (BDNF) polymorphism (Val66Met) and the clinical response of patients with major depressive disorder to selective serotonin reuptake inhibitors (SSRIs; here, paroxetine and sertraline). In addition, serum BDNF levels in these patients were considered together with the clinical response.

Methods

A total of 132 patients who met the DSM-IV criteria for major depressive disorder were enrolled in the study. 54 of these patients were male and 78 were female (age range, 20-74 years; mean ± S.D., 51 ± 15). The patients' clinical improvement was evaluated using the 17-item Hamilton Rating Scale for Depression (HAMD-17) before (T0) and at 8 weeks after the administration of SSRI treatment (T8). Patients with at least a 50% decrease in the HAMD-17 score were classified as responders.

Results

No correlation was observed between the BDNF Val66Met polymorphism and response to SSRIs or between the BDNF Val66Met polymorphism and serum BDNF levels at T0. An inverse correlation was found between serum BDNF levels and HAMD-17 scores at T0.

Conclusions

These results suggest that the BDNF Val66Met polymorphism is independent of both the response to SSRI treatment and serum BDNF levels. The findings in the present study reconfirm that the serum BDNF level is a state biomarker for depression.     

Quality of life in 1931 adult patients with epilepsy: seizures do not tell the whole story

Objective

The aim of the work described here was to characterize quality of life (QOL) and its determinants in a large cohort of adult patients with epilepsy.

Methods

Validated measures reflecting disease severity and psychosocial functioning were electronically collected on all outpatients seen during 2009. Multivariate regression adjusting for repeated measures identified determinants of QOL, as defined by the Quality of Life in Epilepsy Questionnaire-10 (QOLIE-10).

Results

Seven thousand seven hundred eighty-four visits from patients with epilepsy were identified. The questionnaire completion rate was 77%, yielding 5960 records corresponding to 1931 individual patients for analysis. Following multivariate modeling, the two most clinically significant QOL predictors were seizure severity (mean QOLIE-10 score = 28.8 if LSSS > 40 vs 19.2 otherwise) and depression (mean QOLIE-10 score = 31.7 if PHQ-9 ≥ 10 vs 19.3 otherwise).

Conclusions

Optimizing quality of life in patients with epilepsy requires an approach that extends beyond controlling seizures. Collection of validated health status measures improving patient management is possible within the setting of routine clinical care.     

Reduced hedonic capacity in major depressive disorder: evidence from a probabilistic reward task

Objective

Anhedonia, the lack of reactivity to pleasurable stimuli, is a cardinal feature of depression that has received renewed interest as a potential endophenotype of this debilitating disease. The goal of the present study was to test the hypothesis that individuals with major depression are characterized by blunted reward responsiveness, particularly when anhedonic symptoms are prominent.

Methods

A probabilistic reward task rooted within signal-detection theory was utilized to objectively assess hedonic capacity in 23 unmedicated subjects meeting DSM-IV criteria for major depressive disorder (MDD) and 25 matched control subjects recruited from the community. Hedonic capacity was defined as reward responsiveness - i.e., the participants’ propensity to modulate behavior as a function of reward.

Results

Compared to controls, MDD subjects showed significantly reduced reward responsiveness. Trial-by-trial probability analyses revealed that MDD subjects, while responsive to delivery of single rewards, were impaired at integrating reinforcement history over time and expressing a response bias toward a more frequently rewarded cue in the absence of immediate reward. This selective impairment correlated with self-reported anhedonic symptoms, even after considering anxiety symptoms and general distress.

Conclusions

These findings indicate that MDD is characterized by an impaired tendency to modulate behavior as a function of prior reinforcements, and provides initial clues about which aspects of hedonic processing might be dysfunctional in depression.     

Mental disorders and cardiovascular disease among adults in the United States

Objective

Numerous population-based studies have found an association between major depression and CVD, though these studies did not assess anxiety disorders. Patient samples have shown associations between anxiety disorders and cardiovascular disease (CVD), but without consideration of depressive disorders. Therefore, it remains unclear whether: (a) both anxiety and depressive disorder are associated with CVD; (b) these associations are generalizable to adults in the community.

Materials and Methods

Data were drawn from the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), a nationally representative sample of 43,093 civilian non-institutionalized participants aged 18 and older.

Results

CVD (total prevalence 3.3%) was associated with increased likelihood of any anxiety disorder (OR = 1.43, (1.20, 1.71)), after adjusting for depressive disorders, as well as Generalized Anxiety Disorder (OR = 1.48 (1.09, 2.01)), Panic disorder (OR = 1.46 (1.12, 1.91)), and specific phobia (OR = 1.29 (1.04, 1.59)). CVD was significantly associated with any mood disorder (OR = 1.34 (1.13, 1.58)) after adjusting for anxiety disorders, though neither the link with major depression, nor other specific mood disorders remained significant after adjustment.

Conclusions

Our findings suggest that anxiety disorders, mood disorders, and CVD are highly comorbid among adults in the United States, and demonstrate the importance of including anxiety disorder assessment in studies of mental and physical comorbidity. These results reveal how the lack of investigation into specific relationships between CVD and the range of mental disorders in population-based studies of risk factors for CVD may obscure important relationships.     

The prevalence of self-harm behaviors among a sample of gastric surgery candidates

Objective

The surgical treatment of obesity is becoming increasingly popular; yet, little is known about the self-harm characteristics and adjunctive self-regulation difficulties of those seeking such surgery. In the literature, one study has explored presurgery suicide attempts and several studies have explored the prevalence of postsurgical completed suicides. However, beyond suicide attempts and completions, little is known about the broader self-harm/self-regulation profiles of these patients. In this study, we examined the prevalence of 22 such behaviors among a sample of gastric surgery candidates.

Method

Using a cross-sectional approach, we examined 121 surgical candidates for 22 self-reported self-harm and self-regulatory behaviors.

Results

The studied behaviors with the highest prevalence rates in this cohort were sexual promiscuity (22.3%), torturing oneself with self-defeating thoughts (20.7%), alcohol abuse (19.0%), and engaging in emotionally abusive relationships (16.5%). With regard to suicide attempts, 9.1% of participants acknowledged a history and 9.1% reported past overdoses.

Conclusions

These data suggest that (a) adjunctive self-regulatory difficulties may affect a substantial minority of individuals who are seeking gastric surgery for obesity (e.g., promiscuity and alcohol abuse), and (b) the anticipated prevalence rate for past suicide attempts in this population appears to be approximately 10%.     

Assessing depression symptoms in those with insomnia: an examination of the beck depression inventory second edition (BDI-II)

Background

Due to concerns about overlapping symptomatology between medical conditions and depression, the validity of the beck depression inventory (BDI-II) has been assessed in various medical populations. Although major depressive disorder (MDD) and primary insomnia (PI) share some daytime symptoms, the BDI-II has not been evaluated for use with insomnia patients.

Method

Participants (N = 140) were screened for the presence of insomnia using the Duke structured clinical interview for sleep disorders (DSISD), and evaluated for diagnosis of MDD using the structured clinical interview for DSM-IV-TR (SCID). Participants’ mean BDI-II item responses were compared across two groups [insomnia with or without MDD) using multivariate analysis of variance (MANOVA), and the accuracy rates of suggested clinical cutoffs for the BDI-II were evaluated using a receiver operating characteristic (ROC) curve analysis.

Results

The insomnia with depression group had significantly higher scores on several items; however, the groups did not differ on insomnia, fatigue, concentration problems, irritability, libido, increased appetite, and thoughts relating to suicide, self-criticism and punishment items. The ROC curve analysis revealed moderate accuracy for the BDI-II’s identification of depression in those with insomnia. The suggested BDI cutoff of ?17 had 81% sensitivity and 79% specificity. Use of the mild cutoff for depression (?14) had high sensitivity (91%) but poor specificity (66%).

Conclusion

Several items on the BDI-II might reflect sleep disturbance symptoms rather than depression per se. The recommended BDI-II cutoffs in this population have some support but a lower cutoff could result in an overclassification of depression in insomnia patients, a documented problem in the clinical literature. Understanding which items discriminate insomnia patients without depression may help address this nosological issue.     

Validation of the Edinburgh Depression Scale during pregnancy

Background

Untreated depression during pregnancy may have adverse outcomes for the mother and her child. Screening for depression in the general pregnant population is thus recommended. The Edinburgh Depression Scale (EDS) is widely used for postpartum depression screening. There is no consensus on which EDS cutoff values to use during pregnancy. The aim of the current study was to examine the predictive validity and concurrent validity of the EDS for all three trimesters of pregnancy.

Methods

In a large unselected sample of 845 pregnant women, the sensitivity, specificity, and validity of the EDS were evaluated. The Composite International Diagnostic Interview (depression module) was used to examine the predictive validity of the EDS. The anxiety and somatization subscales of the Symptom Checklist 90 (SCL-90) were used to examine its concurrent validity. Only women with a major depressive episode were considered as cases.

Results

The prevalence of depression decreased toward end term: 5.6%, 5.4%, and 3.4%. The EDS scores also decreased toward end term, while the SCL-90 subscale anxiety scores increased. The EDS showed high test-retest reliability and high concurrent validity with the SCL-90 anxiety and somatization subscales. The area under the receiver operating characteristic curve was high and varied between 0.93 and 0.97. A cutoff value of 11 in the first trimester and that of 10 in the second and third trimesters gave the most adequate combination of sensitivity, specificity, and positive predictive value.

Conclusions

The EDS is a reliable instrument for screening depression during pregnancy. A lower cutoff than commonly applied in the postpartum period is recommended.     

Brief cognitive-behavioral therapy with fibromyalgia patients in routine care

Objective

The purpose of the present study was to evaluate the effectiveness of a brief cognitive-behavioral therapy (CBT) group intervention for fibromyalgia syndrome in routine care.

Method

Thirty-four female outpatients who participated in a 5- to 6-week group CBT program were assessed for depression (Beck Depression Inventory), anxiety (State-Trait Anxiety Inventory), coping strategies (Coping Questionnaire for Chronic Pain), physical functioning (Fibromyalgia Impact Questionnaire), and somatization (Health Attitude Survey) at 3 time points (baseline, pretreatment, and posttreatment) using a pre-post, quasi-experimental design.

Results

Twenty-three female outpatients (68% of the initial sample) for which data were available in all 3 time points were included in the analyses. No changes were found during the waiting period. During the treatment period, there were significant reductions in depression (P = .001) and anxiety (P = .006) symptoms and an increased use of distraction skills (P < .001). The analysis of rate of change showed a significant correlation between anxiety and depression (P = .004), but not between these variables and the use of distraction as a coping strategy.

Conclusion

Brief group CBT is effective in reducing emotional distress in female patients with long-standing fibromyalgia syndrome in the context of routine care. Attention-distraction skills appear to be amenable to change by means of brief CBT, but further research is needed to clarify their contribution to short-term clinical improvement.     

Depression in college: depressive symptoms and personality factors in Beijing and Hong Kong college freshmen

Objectives

The present study investigated the 2-week prevalence of depressive symptoms in college freshmen from Beijing and Hong Kong. The relationship between depression and 3 personality factors in these college freshmen was analyzed.

Method

Center for Epidemiologic Studies Depression Scale (CES-D), Eysenck Personality Questionnaire-Neuroticism, Rosenberg Self-esteem Scale, and Frost Multidimensional Perfectionism Scale were administered to 988 Beijing and 802 Hong Kong Chinese college freshmen.

Results

Approximately 24.8% of freshmen in Beijing had scores on the CES-D exceeding 16, whereas 8.9% reported scores of 25 or higher. There was no sex difference in prevalence in Beijing. Approximately 43.9% of freshmen in Hong Kong had scores on the CES-D exceeding 16, whereas 17.6% reported scores of 25 or higher. The prevalence is significantly different between sexes in Hong Kong, with approximately 36.1% of men having scores of 16 or higher and 13.4% having scores of 25 or higher and approximately 50.7% of women having scores of 16 or higher and 21.3% having scores of 25 or higher. High neuroticism, concern over mistakes, doubts about actions, low self-esteem, and poor organization were associated with current depressive symptoms in both sites.

Conclusion

The higher prevalence of current depressive symptoms in college freshmen in Hong Kong suggests that their mental health is not as satisfactory as that of their counterparts in Beijing. The strong relationship between certain personality features and current depressive symptoms is similar in both regions. Personality differences in the 2 sites explain only part, but not all, of the difference in depressive symptoms between the 2 sites.     

Prevalence of psychiatric disorders in patients with polycystic ovary syndrome

Objective

To investigate the prevalence of psychiatric disorders among women in ambulatory treatment for polycystic ovary syndrome (PCOS) and to correlate its clinical and demographic aspects with mental disorders.

Methodology

Seventy-two patients in ambulatory treatment at the Endocrinal and Gynaecological Institute of the Federal University of Rio de Janeiro were evaluated using Diagnostic and Statistical Manual for Mental Disorders, Fourth Edition criteria by means of MINI (Mini International Neuropsychiatric Interview, version 4.4). Polycystic ovary syndrome was confirmed according to the ultrasonographic criteria of Adams and by clinical parameters.

Results

Forty-one patients (57%) presented at least one psychiatric diagnosis. Among them, the prevalence of mood disorder reached 78%. The most prevalent diagnostics were major depression (26.4%) and bipolar disorder (11.1%).

Conclusion

A high prevalence of mental disorders was observed, especially major depression and bipolar disorder. The data obtained regarding the relationship between PCOS and mood disorders in a Brazilian sample is in accordance with recent research findings in the same area.
