RESUMO

PURPOSE: To corroborate the factor structure of the brief Spanish Zung Self-Rating Depression Scale among patients with chronic pulmonary obstructive disease at Santa Marta, Colombia. DESIGN AND METHODS: A psychometric study was done in which 409 patients with the chronic obstructive pulmonary disease were included, aged between 40 and 102 years. Participants completed the 10 items on the brief Spanish Zung Self-Rating Depression Scale. Confirmatory factor analysis was performed. FINDINGS: The two-dimensional structure was confirmed. The goodness of fit indicators was acceptable. PRACTICAL IMPLICATION: The brief Spanish Zung scale for depression has a clear two-dimensional structure for evaluating depressive symptoms in patients with chronic obstructive pulmonary disease. New studies should prove this dimensionality in patients with other clinical conditions.

RESUMO

BACKGROUND: Fabry disease (FD) is a lysosomal disease in which mutations affect the GLA gene located on the X chromosome. The defective product, the enzyme alpha-galactosidase A, causes accumulation of substrate and contributes to the disruption of cell function in several organs, with variable severity and consequent damage of tissue or organ function. Patient reported outcomes (PROs) enable patients to provide information regarding the consequences of their disease and its treatment and are often recognized as the most important outcomes for them. OBJECTIVES: To evaluate pain, depression, sleep disturbances, disability and disease impact on quality of life in a cohort of Brazilian FD patients and compare between groups stratified by the Mainz Symptom Severity Index (MSSI) Methods: Thirty-seven genotype confirmed classic FD patients - 16 male and 21 female - (mutations: C142R, A156D, L180F, R227X, W262X, G271A, P293S, Y264SX) were evaluated and answered the following questionnaires: Brief Pain Inventory (BPI), Hamilton Depression Rating Scale (HAM-D), Pittsburgh Sleep Quality Index (PSQI), Health Assessment Questionnaire Disability Index (HAQ-DI), Short-Form Health Survey 36 (SF-36). RESULTS: In FD patients, mean ± SD BPI severity result was 2.78 ± 2.66 for severe; 2.80 ± 2.55 for moderate and 1.55 ± 2.38 for mild severity patients. Mean ± SD BPI interference result was 2.55 ± 2.44 for severe; 2.80 ± 3.18 for moderate and 1.36 ± 2.83 for mild patients. BPI severity and interference values correlated with MSSI scores (r = 0.24; p < .001 / r = 0.25; p < .001). Application of HAM-D indicated depression in 21 patients (56.8%). HAM-D results had positive correlation with MSSI values (r = 0.21; p < .001), with BPI severity (r = 0.54; p < .001) and interference (r = 0.65; p < .001). PSQI depicted sleep disturbances in 22 patients (59.5%). PSQI values correlated with MSSI values (r = 0.25; p < .001), with HAM-D results (r = 0.65; p < .001) and BPI severity (r = 0.47; p < .001) and interference (r = 0.66; p < .001). Mean HAQ-DI result was 0.490 for severe; 0.274 for moderate and 0.157 for mild severity patients. CONCLUSIONS: Depression, sleep disturbances and disability were under-recognized in FD patients. HAQ-DI revealed worse disability according to MSSI severity status. The lowest raw scores from the SF-36 questionnaire were for the domains general health perception and physical role functioning. Standardized assessments should be routine care and started as early as diagnosis of Fabry disease is made.

RESUMO

Abstract Introduction Although bipolar disorder (BD) is traditionally included among mood disorders, some authors believe that changes in energy and motor activity, rather than mood changes, represent the true cardinal symptoms in mania and depression. The aim of the current study was to identify which cluster of the Hamilton Depression Rating Scale (HAM-D) better distinguishes between mania, depression and euthymia. Method A group of 106 patients with BD were followed for 13 years and repeatedly assessed with the HAM-D as well as with other clinical scales. To perform a comparison, HAM-D items were classified according to clinical criteria into three clusters: energy/activity symptoms, mood symptoms, and other symptoms. Item response theory (IRT) analyses were performed to provide a test information curve for those three clusters. We measured the prevalence of one cluster of symptoms over the other two throughout the latent trait. Results Considering HAM-D items individually, the IRT analysis revealed that there was a mixture of mood and energy/activity symptoms among the most discriminative items, both in depression and in euthymia. However, in mania, only energy/activity symptoms - i.e., general somatic symptoms and retardation - were among the most informative items. Considering the classification of items, both in depression as in mania, the energy/activity cluster was more informative than the mood cluster according to the IRT analysis. Conclusion Our data reinforce the view of hyperactivity and motor retardation as cardinal changes of mania and depression, respectively.

Resumo Introdução Embora o transtorno bipolar (TB) seja tradicionalmente incluído entre os transtornos do humor, alguns autores acreditam que as alterações na energia e na atividade motora, em vez das alterações no humor, representam os verdadeiros sintomas cardinais na mania e na depressão. O objetivo do presente estudo foi identificar qual grupo da Escala de Depressão de Hamilton (HAM-D) distingue melhor entre mania, depressão e eutimia. Método Um grupo de 106 pacientes com TB foram acompanhados por 13 anos e avaliados repetidamente com a HAM-D e com outras escalas clínicas. Para realizar uma comparação, os itens da HAM-D foram classificados de acordo com critérios clínicos em três grupos: sintomas de energia/atividade, sintomas de humor e outros sintomas. Foram realizadas análises da teoria da resposta ao item (TRI) para fornecer uma curva de informações de teste para esses três grupos. Medimos a prevalência de um grupo de sintomas em comparação aos outros dois através do traço latente. Resultados Considerando os itens da HAM-D individualmente, a análise da TRI revelou que havia uma mistura de sintomas de humor e de energia/atividade entre os itens mais discriminativos, tanto na depressão quanto na eutimia. No entanto, na mania, apenas os sintomas de energia/atividade - ou seja, sintomas somáticos gerais e retardo - estavam entre os itens mais informativos. Considerando a classificação dos itens, tanto na depressão quanto na mania, o grupo energia/atividade foi mais informativo que o grupo humor, de acordo com a análise da TRI. Conclusão Nossos dados reforçam a visão da hiperatividade e do retardo motor como as alterações cardinais de mania e depressão, respectivamente.

RESUMO

BACKGROUND: Abnormal activity of two enzymes relevant to neurodevelopment, namely nuclear-distribution element-like 1 (Ndel1) and angiotensin I-converting enzyme (ACE), was reported in individuals with schizophrenia; to our knowledge, these oligopeptidases were never measured in bipolar disorder (BD). AIMS: Evaluate the enzyme activity of Ndel1 and ACE in euthymic individuals with BD type 1 which was compare to healthy control (HC) group. METHODS: Ndel1 and ACE activities were assessed in the serum of individuals with BD type 1 according to DSM-IV criteria (n = 70) and a HC group (n = 34). The possible differences between BD type 1 and HC groups were evaluated using Analysis of Covariance (ANCOVA), and the results were adjusted for age, gender and body mass index. RESULTS: We observed a positive correlation between Ndel1 activity and the total YMRS score in BD group (p = 0.030) and a positive correlation between ACE activity and Ham-D score (p = 0.047). ANCOVA analysis showed lower Ndel1 activity in BDs compared to HCs. Interestingly, we did not observe between-groups differences in ACE activity, despite the recognized correlation of ACE activity levels with cognitive functions, also described to be worsened in psychiatric patients. CONCLUSION: Oligopeptidases, especially Ndel1, which has been strongly correlated with neurodevelopment and brain formation, are potentially a good new target in the study of the neurobiology of BD. LIMITATIONS: The relatively small sample size did not permit to examine the cause-effect relationship of clinical dimensions of BD and the enzymatic activity.

RESUMO

Introducción: La hiperplasia prostática benigna (HPB) es una enfermedad caracterizada por síntomas del tracto urinario inferior (1). Estos síntomas suelen causar un impacto negativo en la calidad de vida del paciente llevándolo a padecer trastornos depresivos (7). Se han encontrado síntomas depresivos hasta en el 22.5% de los pacientes con HPB sin embargo, hay poca evidencia de que estos síntomas disminuyan luego de tratar la HPB (5). Una herramienta útil para medir los síntomas depresivos es la Escala de Medición de Depresión de Hamilton (3). Objetivos: Este estudio pretende evaluar la presencia de síntomas depresivos en pacientes con HPB y comprobar si estos síntomas disminuyen posteriormente al tratamiento quirúrgico para HPB. Métodos. Se utilizó un muestra de 30 pacientes, edad (promedio 67 ± 8 años), sometidos a tratamiento quirúrgico para HPB y quienes presentaran por lo menos un síntoma depresivo según la escala de medición de depresión de Hamilton. Resultados. Todos tuvieron resección transuretral de próstata (RTUP). Previo a la cirugía se encontraron síntomas depresivos en el 76%. Un mes posterior a la cirugía se encontraron síntomas depresivos en 28, sin embargo, se encontró depresión leve en el 23.3% (vs pre op 30%), depresión moderada en el 16.6% (vs pre op 30%) y depresión severa en el 13.3% (vs pre-op 16.6%). La Escala de Medición de Depresión de Hamilton tuvo una puntuación media preoperatoria de 13.93 puntos. Un mes posterior a la cirugía la puntuación media fue de 9.36 puntos. La diferencia fue de 4.56 puntos, lo cual es estadísticamente significativo (P=0.05). Hubo complicaciones quirúrgicas en 3 pacientes quienes tuvieron un aumento en el puntaje postoperatorio y hubo aumento del nivel de depresión. En el estudio 15 refirieron disfunción eréctil previo a la cirugía y únicamente 8 persistieron con disfunción luego de la cirugía. Conclusiones. Los pacientes con HBP constituyen una población en riesgo de padecer síntomas depresivos. Los síntomas depresivos están relacionados con padecer STUI y disfunción eréctil; ambas condiciones afectan la calidad de vida. El tratamiento quirúrgico para tratar la HPB es efectivo en disminuir los síntomas depresivos mejorando la calidad de vida causando mínimos efectos negativos.

Introduction: Benign Prostatic Hyperplasia (BPH) is a condition that leads to inferior urinary tract symptoms (1). These symptoms often cause a negative impact on the quality of life leading to depressive symptoms (7). Depressive symptoms are present in up to 22.5% of patients with BPH, however, there is limited evidence that these symptoms decrease with HPB treatment (5). A useful tool to measure depressive symptoms is the Hamilton Depression Rating Scale (HDRS) (3). Objective: Main purpose of the study is to assess the prevalence of depressive symptoms in patients with BPH and determine whether these symptoms decreased after a corrective surgery. Methods: A sample of 30 male patients, average age 67 ± 8 years old, with surgical treatment indication for BPH, with at least one depressive symptom according to the HDRS was obtained. Results: All patients in the study underwent transurethral resection of the prostate (TURP). Prior to surgery, depressive symptoms found in 76.6%. A month post-surgery depressive symptoms found in 28, however mild depression was present in 23.3% (vs pre-op 30%) moderate depression in 16.6% (vs pre-op 30.0%) and severe depression in 13.3% (vs pre-op 16.6%). Measurement with HDRS had a mean preoperative score 13.93 points; a post-surgery month the average score was 9.36. The difference was 4.56 points; which is statistically significant (P = 0.05). Three patients had surgical complications and they had an increase in postoperative score and also increased in the level of depression. In the study 15 patients reported erectile dysfunction prior to surgery; out of these patients only 8 persisted with dysfunction after surgery. Conclusions: BPH patients is a population at risk for developing depressive symptoms. Depressive symptoms are related to developing lower urinary tract symptoms and erectile dysfunction; both conditions affecting the quality of life. Surgery to treat BPH is effective in reducing depressive symptoms by improving the quality of life and with minimal adverse effects.

RESUMO

OBJETIVO: Determinar os pontos de melhor sensibilidade e especificidade do Inventário de Depressão de Beck (BDI) e da Escala de Avaliação de Depressão de Hamilton (HAM-D) no diagnóstico de depressão associada à epilepsia. MÉTODOS: Setenta e três pacientes de um centro de referência no tratamento da epilepsia foram submetidos à avaliação neuropsiquiátrica. Foram colhidos dados clínicos e sociodemográficos, sendo utilizados os seguintes instrumentos: entrevista clínica estruturada (MINI-PLUS) para diagnóstico psiquiátrico conforme o DSM-IV, HAM-D e BDI. RESULTADOS: No momento da entrevista, 27,4 por cento dos pacientes estavam deprimidos e 37 por cento preenchiam critérios para diagnóstico de depressão maior ao longo da vida. A análise da curva ROC indicou que o ponto de corte em 16 (> 16) para o BDI (sensibilidade de 94,4 por cento, especificidade de 90,6 por cento) e em 16 (> 16) para a HAM-D (sensibilidade de 95 por cento, especificidade de 75,5 por cento) representou dicotomização ótima entre deprimidos e não deprimidos. Ambos os instrumentos apresentaram um valor preditivo negativo superior a 95 por cento. CONCLUSÃO: A frequência de depressão maior é elevada em pacientes com epilepsia. BDI e a HAM-D podem auxiliar o clínico na identificação da depressão associada à epilepsia, diminuindo seu subdiagnóstico.

OBJECTIVE: To determine cutoff points of highest sensitivity and specificity on the Beck Depression Inventory (BDI) and Hamilton Depression Rating Scale (HAM-D) for depression diagnosis in epilepsy. METHODS: Seventy-three patients from a referral center for the treatment of epilepsy underwent neuropsychiatric evaluation. We collected clinical and socio-demographic data, and applied the following instruments: Structured Clinical Interview (MINI-PLUS) for psychiatric diagnosis according to DSM-IV, HAM-D and BDI. RESULTS: At assessment, 27.4 percent of the patients were depressed and 37 percent met diagnostic criteria for lifetime major depression. The ROC curve analysis indicated that a score > 16 on the BDI (94.4 percent sensitivity, 90.6 percent specificity) and > 16 on the HAM-D (95 percent sensitivity, 75.5 percent specificity) revealed great dichotomy between depressed and nondepressed patients. Both instruments showed a negative predictive value exceeding 95 percent. CONCLUSION: The frequency of major depression is elevated in patients with epilepsy. BDI and HAM-D can help physicians in the identification of depression in epilepsy, reducing its underdiagnosis.

RESUMO

El objetivo de este estudio fue evaluar la utilidad de la escala para depresión de Hamilton (EDH) en la detección de trastornos depresivos en pacientes médicos hospitalizados. Los pacientes inicialmente fueron entrevistados con una guía estructural para la EDH y seguidamente una entrevista clínica. Un total de 57 pacientes fue evaluado, con una edad promedio de 45.1 años. 51.6% hombres y 43.9% mujeres. La concordancia absoluta entre la entrevista clínica y la EDH fue de 0.68, la prueba kappa fue de 0.31. Se concluye que la EDH es un instrumento poco útil en la detección de trastornos depresivos en pacientes hospitalizados con problemas médicos. Es probable que los síntomas somáticos comunes a la condición médica y a los trastornos depresivos expliquen este resultado...

The objective of this study was to evaluate the utility of Hamilton Depression Rating Scale (HDRS) for detecting depressive disorders in medical inpatients. Patients were interviewed, first using HDRS with a structured interview guide and last a clinical evaluation. Fifty-seven patients were evaluated, with age average of 45.1 years. 56.1% male and 43.9% female. The absolute concordance was 0.68, but kappa test was 0.31. We conclude that HDRS is not useful in medical inpatients. It is likely somatic symptoms common both medical condition and depressive disorders explain this results...
