RESUMEN
OBJECTIVE: Few studies have focused on medical students and residents' mental health impact on medical residency selection (MRS) performance. The authors evaluated the association of performance in MRS with depressive and anxiety symptoms and with a reported psychiatric diagnosis (rPD). METHODS: The authors enrolled candidates after the second round of MRS examinations at a Brazilian Medical School. Performance was assessed by final grade. Depressive and anxiety symptoms were assessed by the Quick Inventory of Depressive Symptomatology Self-Report (QIDS-SR) and the State-Trait Anxiety Inventory (STAI). The authors performed mediation analysis and multiple linear regression analysis to investigate the impact of rPD, state and trait anxiety, and depressive symptom severity on performance. RESULTS: 515 of the 643 MRS candidates (80.1%) participated in the study. Higher age, attending a preparatory course for MRS, rPD, and the number of MRS applications that year were associated with poorer performance. In mediation analysis, trait anxiety was associated with a direct effect on performance and an indirect effect mediated by rPD. CONCLUSION: The data suggest that psychiatric diagnosis is associated with poorer performance on MRS, regardless of current symptoms of anxiety and depression. Additionally, increased levels of trait anxiety may negatively impact performance, directly and indirectly.
RESUMEN
Background: Depressive symptoms have been associated with cognitive impairment after stroke, and women may be specifically affected. Objective: The aim of this study was to investigate gender-specific characteristics in the relationship between changes in depression severity and changes in cognitive performance after stroke. Methods: We prospectively evaluated 73 patients without a previous history of depression in the first and fourth months after a first ischemic stroke. The severity of depressive symptoms was assessed using the 31-item version of the Hamilton Rating Scale for Depression, and executive function, attention, working memory, and verbal fluency were assessed using a neuropsychological battery. Results: We included 46 (63.0%) men and 27 (36.9%) women, with mean ages of 55.2 (SD ± 15.1) and 46.8 (SD ± 14.7) years, respectively. We found significant improvement in the digit span forward and Stroop dots from month 1 to month 4 post stroke for both men and women. Women, but not men, presented a correlation between changes in phonemic verbal fluency and changes in the 31-item version of the Hamilton Rating Scale for Depression scores. Improvement in depression was correlated with improvement in verbal fluency, and worsening in depression was correlated with worsening in verbal fluency. Conclusions: Our results suggest that women might be more vulnerable to the relationship between depressive symptoms and cognitive performance, and improvement of depression may be necessary for women's improvement in phonemic verbal fluency from the first to the fourth month after a stroke. We did not adjust the results for multiple comparisons. Thus, our findings might be considered preliminary, and confirmatory studies, also focusing on specific characteristics of women that could explain these differences, are warranted.
RESUMEN
BACKGROUND: Burnout, by definition, is related to adverse chronic workplace stressors. Life events outside the workplace have been associated with an increased risk of psychiatric morbidity. However, it is unknown whether life events outside the workplace increase the severity of burnout. PURPOSE: The aim of the study was to investigate the association between burnout and life events outside the workplace in nursing assistants. METHODS: In an observational, cross-sectional, single-site study of 521 nursing assistants at a university hospital, we assessed burnout with the Maslach Burnout Inventory-Human Services Survey, and life events with the Social Readjustment Rating Scale. We constructed equations of multiple linear regression analyses that included each burnout subscale as the dependent variable and a domain of life events as the independent variable. Results were adjusted for potential confounders, including gender, no religion or faith, years of work, and depression. RESULTS: An increase in the number of life events in the domain of personal changes or difficulties (e.g., personal injury or illness, sexual difficulties, change in recreation, church activities, social activities, sleeping habits, eating habits and revision of personal habits) was associated with increased severity of emotional exhaustion. An increase in the number of life events in the domain of changes in familial situation and in the domains of death of relatives or friends were associated with increased severity of depersonalization. Those associations were independent of work-related life events and other potential confounders. CONCLUSIONS: Life events outside the workplace may increase the levels of burnout in nursing assistants.

Background: The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) is the most commonly used instrument to assess burnout. Although various factors have been reported to influence its validity, the influence of major depressive disorder (MDD) has not been previously considered. We developed this study to investigate the influence of MDD on the psychometric properties of the MBI-HSS in nursing assistants. Results: From a sample of 521 nursing assistants, we found in those with MDD (n = 138, 24.56%) a degree of data misfit into the model, revealed by non-acceptable values for the root mean square error of approximation (RMSEA; 0.073; p = 0.004) and for the comparative fit index (CFI; 0.912), while in the non-MDD group these indices were acceptable and good, respectively, for RMSEA (0.048; p = 0.639) and for CFI (0.951). Also, we found higher coefficients of correlation among MBI-HSS factors and less items loading properly in their respective factors in the MDD subset, when compared to the non-MDD subset. For the total sample, while original 3-factor solution was an acceptable model, the bifactor model fitted data better. Conclusions: MDD may impair the construct validity of MBI-HSS subscales, by increasing measurement error and decreasing model fitness. Therefore, researchers and health professionals should be aware of potential changes in the psychometric properties of the MBI-HSS when applied in subjects with depression.
RESUMEN
OBJECTIVES: We developed this study to investigate the association of fibromyalgia with personality traits, controlling for depression and other potential confounders. METHODS: We assessed personality traits using the Cloninger's Temperament and Character Inventory (TCI) in 78 female patients with fibromyalgia and in a control group of 78 subjects without fibromyalgia. The Mini-International Neuropsychiatric Interview was used to assess depression and anxiety diagnoses. To investigate the association between fibromyalgia and the Cloninger's Temperament and Character Inventory we performed unadjusted and adjusted analyses of covariance, using the TCI score as dependent variable and adjusting the model for depression, anxiety and for clinical and socio-demographic variables. We used a backward selection method to choose the final model. RESULTS: In the unadjusted analysis, fibromyalgia was associated with all personality traits, except persistency. After adjusting for depression and anxiety, patients with fibromyalgia presented decreased novelty seeking compared to controls; the differences in other personality traits were no longer significant. Novelty seeking was also correlated with the length of history of fibromyalgia and pain intensity. CONCLUSIONS: Decreased novelty seeking may be a personality trait associated with fibromyalgia. Depression and anxiety should be considered potential confounders in the evaluation of personality traits in this population.

BACKGROUND: Anhedonia constitutes a coherent construct, with neural correlates and negative clinical impact, independent of depression. However, little is known about the neural correlates of anhedonia in stroke patients. In this study, we investigated the association of post-stroke anhedonia with salivary cortisol levels and stroke location and volume. PATIENTS AND METHODS: A psychiatrist administered the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition to identify anhedonia in 36 inpatients, without previous depression, consecutively admitted in a neurology clinic in the first month after a first-ever ischemic stroke. Salivary cortisol levels were assessed in the morning, evening, and after a dexamethasone suppression test. We used magnetic resonance imaging and a semi-automated brain morphometry method to assess stroke location, and the MRIcro program according to the Brodmann Map to calculate the lesion volume. RESULTS: Patients with anhedonia had significantly larger diurnal variation (P-value =0.017) and higher morning levels of salivary cortisol (1,671.9±604.0 ng/dL versus 1,103.9±821.9 ng/dL; P-value =0.022), and greater stroke lesions in the parahippocampal gyrus (Brodmann area 36) compared to those without anhedonia (10.14 voxels; standard deviation ±17.72 versus 0.86 voxels; standard deviation ±4.64; P-value =0.027). The volume of lesion in the parahippocampal gyrus (Brodmann area 36) was associated with diurnal variation of salivary cortisol levels (rho=0.845; P-value =0.034) only in anhedonic patients. CONCLUSION: Our findings suggest that anhedonia in stroke patients is associated with the volume of stroke lesion in the parahippocampal gyrus and with dysfunction of the hypothalamic-pituitary-adrenal axis.
RESUMEN
The depression-executive dysfunction syndrome, a late-onset depression of vascular origin with executive dysfunction and psychomotor retardation, has also been described after stroke. We verified whether this syndrome also occurs in nonelderly stroke patients by investigating the association between domains of depressive symptoms with executive functions in 87 first-ever ischemic stroke patients. The retardation domain of the 31-item Hamilton Rating Scale for Depression was associated with decreased performance on verbal fluency (assessed with FAS). The association was maintained for younger patients (aged <60 years) after adjusting for confounders. This result supports the clinical presentation of depression-executive dysfunction syndrome in younger stroke patients. Confirmation of this finding, its neural correlates, and clinical implication deserve further investigation.

There has been a rapid increase in the use of polypharmacy in psychiatry possibly due to the introduction of newer drugs, greater availability of these newer drugs, excessive confidence in clinical trial results, widespread prescribing of psychotropic medications by primary care, and pressure to augment with additional medications for unresolved side effects or greater efficacy. Even the new generation of medications may not hold significant advantages over older drugs. In fact, there may be additional safety risks with polypharmacy being so widespread. Washout, as a clinical tool, is rarely done in medication management today. Studies have shown that augmenting therapy with additional medications resulted in 9.1%-34.1% dropouts due to intolerance of the augmentation, whereas studies of medication washout demonstrated only 5.9%-7.8% intolerance to the washout procedure. These perils justify reconsideration of medication washout before deciding on augmentation. There are unwarranted fears and resistance in the medical community toward medication washout, especially at the moment a physician is trying to decide whether to washout or add more medications to the treatment regimen. However, medication washout provides unique benefits to the physician: it establishes a new baseline of the disorder, helps identify medication efficacy from their adverse effects, and provides clarity of diagnosis and potential reduction of drug treatments, drug interactions, and costs. It may also reduce overall adverse events, not to mention a potential to reduce liability. After washout, physicians may be able to select the appropriate polypharmacy more effectively and safely, if necessary. Washout, while not for every patient, may be an effective tool for physicians who need to decide on whether to add potentially risky polypharmacy for a given patient. The risks of washout may, in some cases, be lower and the benefits may be clearly helpful for diagnosis, understanding medication effects, the doctor/patient relationship, and safer use of polypharmacy if indicated.
RESUMEN
INTRODUCTION: Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia. OBJECTIVE: The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance). METHOD: A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale. RESULTS: A current major depressive episode was diagnosed in 28 (40.5%) of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found. CONCLUSIONS: The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.

OBJECTIVE: Little is known about the relevance of lesion in neural circuits reported to be associated with major depressive disorder. We investigated the association between lesion stroke size in the limbic-cortical-striatal-pallidal-thalamic (LCSPT) circuit and incidence of major depressive episode (MDE). METHODS: We enrolled 68 patients with first-ever ischemic stroke and no history of major depressive disorder. Neurological and psychiatric examinations were performed at three time-points. We diagnosed major depressive episode, following DSM-IV criteria. Lesion location and volume were determined with magnetic resonance imaging, using a semi-automated method based on the Brodmann Cytoarchitectonic Atlas. RESULTS: Twenty-one patients (31%) experienced major depressive episode. Larger lesions in the left cortical regions of the LCSPT circuit (3,760 vs. 660 mm3; P = 0.004) were associated with higher incidence of MDE. Secondary analyses revealed that major depressive episode was associated with larger lesions in areas of the medial prefrontal cortex including the ventral (BA24) and dorsal anterior cingulate cortex (BA32) and subgenual cortex (BA25); and also the subiculum (BA28/36) and amygdala (BA34). CONCLUSIONS: Our findings indicate that depression due to stroke is aetiologically related to the disruption of the left LCSPT circuit and support the relevance of the medial prefrontal cortex dysfunction in the pathophysiology of depression.

OBJECTIVE: Post-stroke major depressive episode is very frequent, but underdiagnosed. Researchers have investigated major depressive episode symptomatology, which may increase its detection. This study was developed to identify the depressive symptoms that better differentiate post-stroke patients with major depressive episode from those without major depressive episode. METHOD: We screened 260 consecutive ischemic stroke patients admitted to the neurology clinic of a university hospital. Seventy-three patients were eligible and prospectively evaluated. We assessed the diagnosis of major depressive episode using the Structured Clinical Interview for DSM-IV and the profile of depressive symptoms using the 31-item version of the Hamilton Depression Rating Scale. For data analysis we used cluster analyses and logistic regression equations. RESULTS: Twenty-one (28.8%) patients had a major depressive episode. The odds ratio of being diagnosed with major depressive episode was 3.86; (95% CI, 1.23-12.04) for an increase of one unit in the cluster composed by the domains of fatigue/interest and retardation, and 2.39 (95% CI, 1.21-4.71) for an increase of one unit in the cluster composed by the domains of cognitive, accessory and anxiety symptoms. The domains of eating/weight and insomnia did not contribute for the major depressive episode diagnosis. CONCLUSION: The domains of retardation and interest/fatigue are the most relevant for the diagnosis of major depressive episode after stroke.

OBJETIVO: O episódio depressivo maior após acidente vascular cerebral é muito frequente, mas é subdiagnosticado. Pesquisas têm investigado a sintomatologia do episódio depressivo maior pós-acidente vascular cerebral, o que pode facilitar sua identificação. Este estudo foi desenvolvido para identificar os sintomas depressivos que melhor diferenciam pacientes com episódio depressivo maior daqueles sem episódio depressivo maior após o acidente vascular cerebral. MÉTODO: Foram triados consecutivamente 260 pacientes com acidente vascular cerebral admitidos à enfermaria de neurologia de um hospital universitário, dos quais 73 pacientes foram acompanhados. Para investigar o diagnóstico de episódio depressivo maior foi utilizada a Entrevista Clinica Estruturada para DSM-IV e para a sintomatologia depressiva a Escala de Avaliação para Depressão de Hamilton, versão 31 itens. Para a análise dos dados foi utilizada a análise de clusters e regressão logística. RESULTADOS: Vinte e um (28,8 por cento) pacientes tiveram episódio depressivo maior. O odds ratio para o diagnóstico de episódio depressivo maior foi 3,86; (95 por cento IC, 1,23-12,04) para um aumento de uma unidade no cluster dos domínios interesse/fadiga e lentificação, e 2,39 (95 por cento IC, 1,21-4,71) para um aumento de uma unidade no cluster de domínios de sintomas cognitivos, acessórios e ansiedade. Os domínios apetite/peso e insônia não contribuíram para o diagnóstico de episódio depressivo maior. CONCLUSÃO: Os domínios de lentificação e interesse/fadiga são os mais relevantes para o diagnóstico do episódio depressivo maior após acidente vascular cerebral.

OBJECTIVE: To investigate the recognition of depressive symptoms of major depressive disorder (MDD) by general practitioners. INTRODUCTION: MDD is underdiagnosed in medical settings, possibly because of difficulties in the recognition of specific depressive symptoms. METHODS: A cross-sectional study of 316 outpatients at their first visit to a teaching general hospital. We evaluated the performance of 19 general practitioners using Primary Care Evaluation of Mental Disorders (PRIME-MD) to detect depressive symptoms and compared them to 11 psychiatrists using Structured Clinical Interview Axis I Disorders, Patient Version (SCID I/P). We measured likelihood ratios, sensitivity, specificity, and false positive and false negative frequencies. RESULTS: The lowest positive likelihood ratios were for psychomotor agitation/retardation (1.6) and fatigue (1.7), mostly because of a high rate of false positive results. The highest positive likelihood ratio was found for thoughts of suicide (8.5). The lowest sensitivity, 61.8%, was found for impaired concentration. The sensitivity for worthlessness or guilt in patients with medical illness was 67.2% (95% CI, 57.4-76.9%), which is significantly lower than that found in patients without medical illness, 91.3% (95% CI, 83.2-99.4%). DISCUSSION: Less adequately identified depressive symptoms were both psychological and somatic in nature. The presence of a medical illness may decrease the sensitivity of recognizing specific depressive symptoms. CONCLUSIONS: Programs for training physicians in the use of diagnostic tools should consider their performance in recognizing specific depressive symptoms. Such procedures could allow for the development of specific training to aid in the detection of the most misrecognized depressive symptoms.

BACKGROUND: Little is known about the treatment of depression in older patients with heart failure. This study was developed to investigate the effectiveness of antidepressant treatment for major depressive disorder (MDD) in the elderly with heart failure. METHODS: We enrolled 72 older outpatients with ejection fraction <50 and diagnosed with MDD by the structured clinical interview for DSM-IV. Thirty-seven patients, 19 on citalopram and 18 on placebo, initiated an 8-week double-blind treatment phase. Measurements were performed with the 31-item Hamilton Rating Scale for Depression (Ham-D-31), the Montgomery-Asberg rating scale (MADRS) and the Systematic Assessment for Treatment Emergent Effects (SAFTEE). A psychiatrist followed up the patients weekly, performing a consultation for about 20 min to field complaints after the measurements. RESULTS: A trend toward superiority of citalopram over placebo in reducing depression was observed in MADRS scores (15.05+9.74 vs 9.44+9.25, P=.082) but not on HAM-D scores. The depressive symptomatology significantly decreased in both groups (P < .001). The high rate of placebo response during the double-blind phase (56.3%) led us to conclude the study at the interim analysis with 37 patients. CONCLUSION: Citalopram treatment of MDD in older patients with heart failure is well-tolerated with low rates of side effects, but was not significantly more effective than placebo in the treatment of depression. Weekly psychiatric follow-up including counseling may contribute to the improvement of depression in this population. Scales weighted on psychological symptoms such as the MADRS are possibly better suited to measure depression severity and improvement in patients with heart failure.

OBJETIVO: Investigar a presença de transtornos psiquiátricos em pacientes com dor torácica de origem não cardíaca que não respondem aos tratamentos regulares. MÉTODO: Dezoito pacientes com dor torácica sem origem cardíaca e considerados por seus clínicos como não respondentes aos tratamentos regulares instituídos foram avaliados por um psiquiatra treinado. As entrevistas foram realizadas com base no Present State Examination e os diagnósticos psiquiá-tricos, de acordo com os critérios do Manual de Diagnóstico e Estatística da Associação Psiquiátrica Americana, 3ª Edição Revisada (DSM-III-R). RESULTADOS: Depressão maior no momento da avaliação foi diagnosticada em 6 (30 por cento) pacientes, somatização em 1 (6 por cento) e transtorno do pânico em 1 (6 por cento) paciente. Sete pacientes estavam recebendo antidepressivos tricíclicos com doses < 75 mg/dia. CONCLUSÕES: A baixa dose de ADTs usadas para o tratamento da dor nesses pacientes pode ter melhorado parcialmente os sintomas depressivos, tornando mais difíceis o diagnóstico e o tratamento apropriado(s) da depressão e, assim, contribuindo para a persistência da dor e outras queixas. As futuras pesquisas deverão focalizar a eficácia do tratamento da depressão nesses pacientes e o impacto deste no alívio da dor torácica não cardíaca.
OBJECTIVE: To investigate the presence of psychiatric disorders in patients with chest pain not responsive to treatment. METHOD: We evaluated 18 patients judged by their physicians to have a chest pain not responsive to usual treatment, which included anti-pain medicines and investigation and treatment of possible etiological causes such as coronary artery disease, and gastroesophageal reflux disease. A psychiatrist interviewed the patients using the Present State Examination and made the diagnosis based on the DSM-III-R criteria. Current major depression was diagnosed in 6 (30 percent) patients, somatization in 1 (6 percent) and panic disorder in 1 (6 percent) patient. Seven patients were receiving tricyclics antidepressant with doses > 75 mg/day. DISCUSSION: Patients were receiving doses of tricyclics antidepressants efficacious for pain but not for major depression. It is possible that the low dose of antidepressants used to treat pain may partially ameliorate depressive symptoms, making the appropriate diagnosis and treatment of major depression even more difficult, consequently contributing to the persistence of pain and other complains. Considering the wide alternatives to effectively treat depression, a focus on detection and treatment of major depression in patients with chest pain is warranted by clinicians and researchers.

The authors evaluated levels of inflammatory markers in 34 chronic heart failure (CHF) out-patients age 65 years and over, with (N=18) and without (N=16) major depressive disorder (MDD), and healthy-control subjects (N=13). Patients with CHF had left-ventricular ejection fractions <0.40 and were in the New York Heart Association functional class II or III. The authors used the SCID DSM-IV to diagnosis MDD. High-sensitivity C-reactive protein levels were significantly higher in patients with CHF and MDD as compared with healthy-control subjects. No differences regarding tumor necrosis factor(alpha) or interleukin(6) were found among the three groups.

BACKGROUND: Studies investigating the performance of instruments to detect major depressive disorder (MDD) have reported inconsistent results. Subsyndromal depression (SD) has also been associated to increased morbidity, and little is known about its detection in primary care setting. This study aimed to investigate the performance of the Primary Care Evaluation of Mental Disorders (PRIME-MD) to detect MDD and any depression (threshold at SD) in an outpatient unit of a teaching general hospital. METHODS: Nineteen primary care physicians using the PRIME-MD evaluated 577 patients, 240 of them (75% female; mean age, 40.0 +/- 14.4), including all with MDD and a randomly subset of those without MDD, were evaluated by 11 psychiatrists using the Structured Clinical Interview Axis I Disorders, Patient Version (SCIDI/P) for DSM-IV as the standard instrument. RESULTS: The kappa between the PRIME-MD and the SCID was 0.42 for the diagnosis of any depression and 0.32 for MDD. The distribution of the number of depressive symptoms per patient suggested the existence of a continuum between SD and MDD, and a high frequency of subjects with 4-6 symptoms (close to the cutoff for the diagnosis of MDD). LIMITATIONS: The sample has a modest size and is a subset of an original one. CONCLUSION: A continuum between SD and MDD may in part explain the relatively low agreement for the diagnosis of MDD in our sample and possibly in other studies. Studies investigating the performance of screening instruments to detect MDD, should consider the relevance of identifying SD, and the influence of the distribution of the number of depressive symptoms in their results.
