Research progress in association of neurological disorders and periodontal diseases / 中华口腔医学杂志

Periodontal diseases are inflammatory diseases caused by oral pathogens around the periodontal supporting tissues, leading to systemic and chronic inflammatory conditions. The continuous chronic systemic inflammation may be a trigger of neuroinflammation, which is the prominent feature of a variety of neurological disorders. It implies that there may be a causal link between periodontal diseases and neurological disorders. This article presents epidemiological and biological evidences that periodontal diseases can induce or exacerbate neurological disorders, including Alzheimer's disease, Parkinson's disease, multiple sclerosis and major depressive disorder, and analyzes the possible mechanisms. The importance of maintaining oral health as well as preventing and treating periodontal diseases are emphasized. At the same time, this may provide novel approaches to study the relationship between periodontal diseases and neurological disorders in the prevention and treatment strategies of neurological disorders.

Prevalence of depression among patients with presumptive pulmonary tuberculosis in Rio de Janeiro, Brazil

Objective: To estimate the prevalence of major depressive episode (MDE) in patients with presumptive pulmonary tuberculosis (pre-PTB, defined by cough lasting ≥ 3 weeks) and compare it between patients with pulmonary tuberculosis (PTB) and without PTB. Methods: Patients with pre-PTB (n=260) were screened for depression using the Patient Health Questionnaire (PHQ-9). Those individuals with scores ≥ 10 were subsequently assessed with the depression module of the Mini International Neuropsychiatric Interview (MINI-Plus) to confirm diagnosis. Associations of categorical variables with PTB and MDE were calculated using the chi-square test and OR. Results: PTB was confirmed in 98 patients (37.7%). A high proportion of both groups (active PTB and no PTB) screened positive for depression (60.2 vs. 62.1%, respectively). Among 159 patients who screened positive for depression, a subset of 97 (61.0%) were further evaluated with the MINI-Plus; current MDE was confirmed in 54.6% (53/97). On univariate and multivariate analysis, female sex was the only factor associated with the diagnosis of current MDE (p = 0.04). Conclusion: The prevalence of MDE was high among individuals with prolonged respiratory symptoms, independent of PTB diagnosis. This is consistent with other studies of depression in primary care in Brazil.

Sexual dysfunction in females with depression: a cross-sectional study / Disfunção sexual em mulheres com depressão: um estudo transversal

Abstract Introduction Female sexual dysfunction (FSD) in depression albeit common is strikingly understudied. The condition, if addressed properly, can be readily cured, improving the quality of life of the patient. Methods A consecutive sample of drug-naïve married female patients with depression was assessed. Depression was diagnosed using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). Depression severity was assessed using the Hamilton Depression Rating Scale (HAM-D), and sexual dysfunction, the Female Sexual Function Index (FSFI). Results Sexual dysfunction was found in 90% of the patients in our study. Patients with medical comorbidities showed a significant decrease in the desire subset of the FSFI (Mann-Whitney U=11.0, p=0.009), however there was no significant association with other subsets. Patients who expressed passive death wishes had higher scores on all indicators of sexual function and a significantly higher score in the orgasm subset of the FSFI (Mann-Whitney U=11.0, p=0.009). Conclusion The study showed a high prevalence of FSD in depressed females regardless of type and severity of depression. Depression with medical comorbidities was associated with a significant decrease in desire. Patients who expressed passive death wishes showed improved sexual function and significantly better orgasm.

Resumo Introdução Disfunção sexual feminina (DSF) na depressão, apesar de comum, é pouco estudada. Se tratada adequadamente, a condição pode ser prontamente curada, aumentando a qualidade de vida da paciente. Métodos Foi avaliada uma amostra consecutiva de mulheres casadas, virgens de tratamento, com depressão. A depressão foi diagnosticada utilizando a Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I). A gravidade da depressão foi avaliada utilizando a Escala de Avaliação de Depressão de Hamilton (HAM-D), e a disfunção sexual, com o Índice da Função Sexual Feminina (Female Sexual Function Index, FSFI). Resultados Foi observada disfunção sexual em 90% das pacientes do estudo. As pacientes com comorbidades médicas mostraram uma diminuição significativa no subdomínio desejo da FSFI (Mann-Whitney U=11,0, p=0,009), porém não houve associação significativa com os outros subdomínios. Pacientes que expressaram desejos passivos de morte apresentaram escores mais altos em todos os indicadores de função sexual e um escore significativamente mais alto no subdomínio orgasmo da FSFI (Mann-Whitney U=11,0, p=0,009). Conclusão O estudo revelou uma alta prevalência de DSF em mulheres deprimidas, independentemente do tipo e da severidade da depressão. A depressão com comorbidades médicas foi associada a uma diminuição significativa do desejo. Pacientes que expressaram desejos passivos de morte mostraram função sexual melhor e orgasmo significativamente melhor.

Major Depression and Acute Coronary Syndrome-Related Factors / Depressão Maior e Fatores Relacionados na Síndrome Coronariana Aguda

Abstract Background: Major Depressive Disorder (MDD) is one of the most common mental illnesses in psychiatry, being considered a risk factor for Acute Coronary Syndrome (ACS). Objective: To assess the prevalence of MDD in ACS patients, as well as to analyze associated factors through the interdependence of sociodemographic, lifestyle and clinical variables. Methods: Observational, descriptive, cross-sectional, case-series study conducted on patients hospitalized consecutively at the coronary units of three public hospitals in the city of Rio de Janeiro over a 24-month period. All participants answered a standardized questionnaire requesting sociodemographic, lifestyle and clinical data, as well as a structured diagnostic interview for the DSM-IV regarding ongoing major depressive episodes. A general log-linear model of multivariate analysis was employed to assess association and interdependence with a significance level of 5%. Results: Analysis of 356 patients (229 men), with an average and median age of 60 years (SD ± 11.42, 27-89). We found an MDD point prevalence of 23%, and a significant association between MDD and gender, marital status, sedentary lifestyle, Killip classification, and MDD history. Controlling for gender, we found a statistically significant association between MDD and gender, age ≤ 60 years, sedentary lifestyle and MDD history. The log-linear model identified the variables MDD history, gender, sedentary lifestyle, and age ≤ 60 years as having the greatest association with MDD. Conclusion: Distinct approaches are required to diagnose and treat MDD in young women with ACS, history of MDD, sedentary lifestyle, and who are not in stable relationships.

Resumo Fundamento: O transtorno depressivo maior (TDM) é um dos distúrbios mentais mais comuns em psiquiatria, sendo um fator de risco para síndrome coronariana aguda (SCA). Objetivo: Avaliar a prevalência de TDM em pacientes com SCA, assim como analisar os fatores associados através da interdependência de variáveis sociodemográficas, clínicas e de estilo de vida. Métodos: Estudo observacional, descritivo e transversal conduzido em pacientes hospitalizados consecutivamente nas unidades coronarianas de três hospitais públicos na cidade do Rio de Janeiro num período de 24 meses. Todos os participantes responderam a um questionário padrão sobre dados sociodemográficos, clínicos e de estilo de vida, assim como participaram de uma entrevista clínica estruturada do DSM-IV sobre episódio depressivo maior atual. Aplicou-se um modelo log-linear de análise multivariada para avaliar associação e interdependência, com nível de significância de 5%. Resultados: Análise de 356 pacientes (229 homens) com idade média e mediana de 60 anos (DP ± 11,42; 27-89). Encontrou-se uma prevalência pontual de TDM de 23%, e significativa associação de TDM com as variáveis sexo, estado civil, sedentarismo, classificação Killip e história de TDM. Ao controlar por sexo, observou-se associação estatisticamente significativa entre TDM e sexo, idade ≤ 60 anos, sedentarismo e história de TDM. O modelo log-linear identificou as variáveis história de TDM, sexo, sedentarismo e idade ≤ 60 anos como tendo a maior associação com TDM. Conclusão: Os resultados indicam a necessidade de abordagens distintas para diagnosticar e tratar TDM em mulheres jovens com SCA, história de TDM, sedentarismo e que não estejam em relações estáveis.

Activity/rest rhythm of depressed adolescents undergoing therapy: case studies / Ritmo de atividade e repouso em adolescentes deprimidos durante terapia: estudos de caso

Abstract Introduction: Disorders of circadian rhythms have been reported in studies of both depressed children and of depressed adolescents. The aim of this study was to evaluate whether there is a relationship between the 24-hour spectral power (24h SP) of the activity/rest rhythm and the clinical course of depression in adolescents. Methods: Six 14 to 17-year-old adolescents were recruited for the study. They were all suffering from major depressive disorder, according to the Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) criteria, as identified by the Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version (K-SADS-PL). Depressive symptoms were assessed using the Children's Depression Rating Scale - Revised (CDRS-R) and clinical evaluations. Locomotor activity was monitored over a period of 13 consecutive weeks. Activity was measured for 10-minute periods using wrist-worn activity monitors. All patients were prescribed sertraline from after the first week up until the end of the study. Results: We found a relationship between high CDRS values and low 24-hour spectral power. Conclusions: The 24h SP of the activity/rest rhythm correlated significantly (negatively) with the clinical ratings of depression.

Resumo Introdução: Distúrbios do ritmo circadiano têm sido relatados em estudos com crianças e adolescentes deprimidos. O objetivo deste estudo foi avaliar se existe relação entre a potência espectral de 24 horas do ritmo de atividade e repouso e sintomas clínicos de depressão em adolescentes. Métodos: Seis adolescentes com idade entre 14 e 17 anos foram recrutados para o estudo. Eles foram diagnosticados com depressão maior de acordo com os critérios do Manual Diagnóstico e Estatístico de Transtornos Mentais, 4ª edição (DSM-IV), identificados utilizando-se o instrumento Schedule for Affective Disorders and Schizophrenia for School Aged Children: Present and Lifetime Version (K-SADS-PL). Os sintomas depressivos foram avaliados pelo questionário Children's Depression Rating Scale - Revised (CDRS-R) e por avaliações clínicas. A atividade motora foi monitorada por um período de 13 semanas consecutivas e registrada a cada 10 minutos utilizando-se monitores de atividades usados no pulso. Todos os pacientes utilizaram o antidepressivo sertralina começando após a primeira semana até o final do estudo. Resultados: Foi observada uma relação entre escores altos no CDRS-R e valores baixos de potência espectral de 24 horas no ritmo de atividade e repouso. Conclusão: A potência espectral de 24 horas do ritmo de atividade e repouso apresentou uma correlação significativa (negativa) com os sintomas clínicos de depressão.

Transcranial magnetic stimulation for treatment of major depression during pregnancy: a review / Estimulação magnética transcraniana para o tratamento de depressão maior durante a gestação: uma revisão

Abstract Introduction: Pregnancy is characterized by a high prevalence of mental disorders. Depression is the most common of these disorders and it is a risk factor for negative maternal and child development outcomes. Psychotherapy and pharmacotherapy are conventional and well-established therapeutic options, but some clients fail to respond and the safety of using some pharmacological agents during pregnancy is unclear. Some neuromodulation techniques, such as repetitive transcranial magnetic stimulation (rTMS), have been studied in depressed pregnant women. Objective: To evaluate the safety and efficacy of rTMS for major depression in pregnant women. Methods: The LILACS and PubMed databases were reviewed using the search terms depression, pregnancy and magnetic stimulation. Texts including primary data, published in Portuguese, Spanish, or English, between 1995 and 2014, that evaluated depressed pregnant women and used rTMS as the intervention were selected. Papers lacking sufficient data were excluded. Twenty-two texts were initially identified; after applying the inclusion criteria, 12 were selected and analyzed. Results: The studies reviewed reported satisfactory responses to rTMS in acute depressive episodes, as measured using depressive symptom scales. Remission of symptoms was achieved in many cases. The procedure was well tolerated and there were no reports of damage/complications to unborn children. Conclusion: The data available at this time support the efficacy and tolerability of rTMS for depression in pregnant women. Controlled studies should corroborate this conclusion. This review only included studies in three languages and the resulting sample size was not large enough to conduct a meta-analysis.

Resumo Introdução: A gestação é caracterizada por uma alta prevalência de transtornos mentais. A depressão é a mais comum entre essas doenças e é fator de risco para desfechos negativos maternos e de desenvolvimento da criança. Psicoterapia e farmacoterapia são opções terapêuticas convencionais e bem estabelecidas, mas algumas pacientes não apresentam resposta, e a segurança do uso de alguns psicofármacos durante a gestação não é clara. Algumas técnicas de neuromodulação, como estimulação magnética transcraniana repetitiva ( repetitive transcranial magnetic stimulation , rTMS), vêm sendo estudadas em gestantes com depressão. Objetivo: Avaliar a segurança e a eficácia da rTMS para depressão maior em mulheres gestantes. Métodos: As bases de dados LILACS e PubMed foram revisadas utilizando os termos depressão, gestação e estimulação magnética. Textos originais, publicados em português, espanhol, ou inglês, entre 1995 e 2014, que avaliaram gestantes com depressão e utilizaram rTMS como intervenção, foram selecionados. Artigos com dados insuficientes foram excluídos. Vinte e dois textos foram inicialmente identificados; após a aplicação dos critérios de inclusão, 12 foram selecionados e analisados. Resultados: Os estudos revisados demonstraram resposta satisfatória com rTMS em episódios depressivos agudos, avaliada com escalas de sintomas depressivos. Houve remissão em muitos casos. O procedimento foi bem tolerado e não houve relatos de danos/complicações aos bebês. Conclusão: Os dados disponíveis até o momento sugerem a eficácia e tolerabilidade de rTMS para depressão em gestantes. Estudos controlados devem corroborar esta conclusão. Esta revisão incluiu apenas estudos em três idiomas e resultou em um tamanho amostral insuficiente para conduzir uma metanálise.

Robin Williams' suicide: a case study / O suicídio de Robin Williams: estudo de caso

Abstract Introduction: The world renowned comedian and four-time Oscar nominated actor Robin Williams died on August 11, 2014. From the outset, the news indicated that his death was believed to be a suicide and this was later confirmed to be true by the autopsy reports. Williams had been suffering from severe depression, which is believed to be the leading contributor to his suicide. In this case study, I will highlight the event of the actor's suicide and the main risk factors along with depression leading to his tragic death. As of the end of 2015, no other case study seemed to have addressed or explored the links between the cause (or causes) and events leading to Robin Williams' suicide. Case description: Robin Williams was suffering from relationship problems, financial problems, drug addiction, and major depression. All of these factors led to his suicide. Comments: The chances of committing suicide drastically increase in the presence of any of the key risk factors. Unfortunately, the actor Robin Williams was dealing with four of the major risk factors all together, which put him at a high risk of committing suicide and eventually led to his tragic death.

Resumo Introdução: O ator Robin Williams, comediante reconhecido internacionalmente e quatro vezes indicado ao Oscar, faleceu no dia 11 de agosto de 2014. Desde o início, os noticiários indicavam que sua morte provavelmente resultara de suicídio, e isso foi confirmado posteriormente nos relatórios da autópsia. Williams vinha sofrendo de depressão severa, a qual, acredita-se, foi o fator que mais contribuiu para seu suicídio. Neste estudo de caso, vou discorrer sobre o suicídio do ator e sobre os principais fatores de risco, além da depressão, que levaram à sua morte trágica. Do final de 2015 para cá, nenhum outro estudo de caso parece ter abordado ou explorado as associações entre a causa (ou as causas) e os eventos que levaram ao suicídio do ator Robin Williams. Descrição do caso: Robin Williams vinha sofrendo com problemas de relacionamento, problemas financeiros, abuso de drogas e depressão severa. Todos esses fatores levaram ao seu suicídio. Comentários: As chances de cometer suicídio aumentam drasticamente na presença de qualquer fator de risco chaves. Infelizmente, o ator Robin Williams estava exposto a quatro fatores de risco chaves simultaneamente, colocando-o sob um alto risco de cometer suicídio, o que eventualmente culminou com sua trágica morte.

A cross-cultural study of gambling disorder: a comparison between women from Brazil and the United States

Objective: To perform a cross-cultural comparison of gambling disorder (GD) in women from Brazil and the United States, two countries with pronounced social and cultural differences. We hoped to produce insight into the impact of cultural influences on the presentation of GD in women, which may be useful for the development of culturally-sensitive interventions. Method: We assessed 681 women with GD: 406 from a Brazilian sample and 275 from a U.S. sample. We assessed demographic and gambling behavior variables in addition to co-occurring psychiatric disorders. Results: Fewer Brazilian participants were Caucasian (73.3 vs. 91.3%; p = 0.022). Also, Brazilian women had lower levels of education (59.9% with high school or less vs. 44.4%; p < 0.001), and were more likely to have a current partner (54.9 vs. 43.4%; p = 0.003). Brazilian gamblers also reported lower urge scores (6.6±4.3 vs. 11.6±2.4; p < 0.001) and higher chasing rates (89.1 vs. 80.0%; p = 0.002). Brazilian gamblers reported higher rates of bingo gambling (19.2 vs. 5.7%; p < 0.001), but lower rates of card game gambling (5.8 vs. 23.1%; p < 0.001). Finally, Brazilian gamblers were more likely to endorse a history of major depressive disorder (36.9 vs. 24.4%; p = 0.001). Conclusions: This study reinforces the need for further general cross-cultural research on GD and particularly for studies investigating how gender mediates these differences. Finally, the differences noted in this analysis suggest that the findings of predominantly Anglo-Saxon cultures may not be generalizable to other world populations.

Symmetry symptoms in obsessive-compulsive disorder: clinical and genetic correlates

Objective: In obsessive-compulsive disorder (OCD), symmetry-related symptoms may be important. Although clinical correlates of symmetry-related symptoms have been identified in OCD, few data exist on genetic associations. Animal studies indicate involvement of dopamine in symmetry-related behavior, suggesting this may be relevant to analogous symptoms in OCD. Alterations in dopamine may also reflect environmental influences. However, the association of symmetry-related symptomatology, early adversity, and polymorphisms in dopaminergic genes has not been investigated in OCD. Methods: Clinical information and polymorphisms in key dopaminergic genes were compared between OCD patients with primary symmetry symptoms and those without. Results: OCD patients with primary symmetry symptoms comprised 46.6% (n=210) of the sample (n=451), and were older (p < 0.01), had longer illness duration (p < 0.01), higher OCD severity scores (p = 0.01), and greater comorbidity (p < 0.01) than those without. In Caucasians (n=343), genotype frequency differed significantly between groups for ANKK1 rs1800497, with more OCD patients with symmetry symptoms being homozygous for the A2 (CC) genotype (χ2 = 7.296; p = 0.026). Conclusion: Symmetry symptoms have some distinct clinical features and may represent a marker of severity in OCD. However, clinical associations, in combination with the association found with the ANKK1 rs1800497 A2 variant, suggest that primary symmetry symptoms may represent a distinctive clinical and psychobiological profile.

Sorafenib prevents liver fibrosis in a non-alcoholic steatohepatitis (NASH) rodent model

Liver fibrosis occurring as an outcome of non-alcoholic steatohepatitis (NASH) can precede the development of cirrhosis. We investigated the effects of sorafenib in preventing liver fibrosis in a rodent model of NASH. Adult Sprague-Dawley rats were fed a choline-deficient high-fat diet and exposed to diethylnitrosamine for 6 weeks. The NASH group (n=10) received vehicle and the sorafenib group (n=10) received 2.5 mg·kg-1·day-1 by gavage. A control group (n=4) received only standard diet and vehicle. Following treatment, animals were sacrificed and liver tissue was collected for histologic examination, mRNA isolation, and analysis of mitochondrial function. Genes related to fibrosis (MMP9, TIMP1, TIMP2), oxidative stress (HSP60, HSP90, GST), and mitochondrial biogenesis (PGC1α) were evaluated by real-time quantitative polymerase chain reaction (RT-qPCR). Liver mitochondrial oxidation activity was measured by a polarographic method, and cytokines by enzyme-linked immunosorbent assay (ELISA). Sorafenib treatment restored mitochondrial function and reduced collagen deposition by nearly 63% compared to the NASH group. Sorafenib upregulated PGC1α and MMP9 and reduced TIMP1 and TIMP2 mRNA and IL-6 and IL-10 protein expression. There were no differences in HSP60, HSP90 and GST expression. Sorafenib modulated PGC1α expression, improved mitochondrial respiration and prevented collagen deposition. It may, therefore, be useful in the treatment of liver fibrosis in NASH.

Memory mood congruency phenomenon in bipolar I disorder and major depression disorder patients

The objective of the present study was to evaluate memory performance in tasks with and without affective content (to confirm the mood congruency phenomenon) in acutely admitted patients with bipolar I disorder (BD) and major depression disorder (MDD) and in healthy participants. Seventy-eight participants (24 BD, 29 MDD, and 25 healthy controls) were evaluated. Three word lists were used as the memory task with affective content (positive, negative and indifferent). Psychiatric symptoms were also evaluated with rating scales (Young Mania Rating Scale for mania and Hamilton Depression Rating Scale for depression). Patients were selected during the first week of hospitalization. BD patients showed higher scores in the word span with positive tone than MDD patients and healthy controls (P = 0.002). No other difference was observed for tests with affective tone. MDD patients presented significantly lower scores in the Mini-Mental State Exam, logical memory test, visual recognition span, and digit span, while BD patients presented lower scores in the visual recognition test and digit span. Mood congruency effect was found for word span with positive tone among BD patients but no similar effect was observed among MDD patients for negative items. MDD patients presented more memory impairment than BD patients, but BD patients also showed memory impairment.

Depressão e trabalho: ruptura de laço social / Depression and work: breaking the social bond

As depressões irrompem o século XXI como mal do século e o mal-estar no trabalho chega ao suicídio. São tempos em que as pessoas se queixam da falta de trabalho, da ameaça de perdê-lo ou das pressões a que se submetem para preservá-lo. O trabalho formal, uma profissão, uma carreira, por sua vez também não são garantia de um presente estável ou um futuro promissor. A depressão é uma das reações a perdas e a ameaças de perda, seja de emprego ou de um contexto social estruturante, que podem induzir à fragmentação da identidade psíquica. Este ensaio discute o termo depressão dentro do contexto das peculiaridades do mal-estar contemporâneo no trabalho, utilizando dados de noticiários, da bibliografia especializada nacional e internacional e da prática clínica em psiquiatria e pesquisa em saúde mental do trabalhador.

Depression emerges in the XXI century as the malady of the century and distress at work can eventually result in suicide. People complain about unemployment, the threat of being unemployed, and to be under pressure in order to keep their jobs. On the other hand, neither a profession nor a career assure a stable present and a promising future. Depression is one of common reactions for loss. Either loosing or being thre atened to loose jobs or a structuring social context could lead to the fragmentation of psychic identity. This essay discusses the word depression within the singularities of contemporary occupational distress, based on current news, specialized national and international literature, as well as the authors psychiatric clinical praxis and research on workers mental health.

Relationship between depression and apolipoproteins A and B: a case-control study

OBJECTIVE: To investigate the relation between major depressive disorder and metabolic risk factors of coronary heart disease. INTRODUCTION: Little evidence is available indicating a relationship between major depressive disorder and metabolic risk factors of coronary heart disease such as lipoprotein and apolipoprotein. METHODS: This case-control study included 153 patients with major depressive disorder who fulfilled the criteria of the Diagnostic and Statistical Manual of Mental Disorders, fourth edition (DSM-IV), and 147 healthy individuals. All participants completed a demographic questionnaire and Hamilton rating scale for depression. Anthropometric characteristics were recorded. Blood samples were taken and total cholesterol, high-and low-density lipoproteins and apolipoproteins A and B were measured. To analyze the data, t-test, χ2 test, Pearson correlation test and linear regression were applied. RESULTS: Depression was a negative predictor of apolipoprotein A (β = -0.328, p<0.01) and positive predictor of apolipoprotein B (β = 0.290, p<0.05). Apolipoprotein A was inversely predicted by total cholesterol (β = -0.269, p<0.05) and positively predicted by high-density lipoprotein (β = 0.401, p<0.01). Also, low-density lipoprotein was a predictor of apolipoprotein B (β = 0.340, p<0.01). The severity of depression was correlated with the increment in serum apolipoprotein B levels and the decrement in serum apolipoprotein A level. CONCLUSION: In view of the relationship between apolipoproteins A and B and depression, it would seem that screening of these metabolic risk factors besides psychological interventions is necessary in depressed patients.

Prevalencia de depresión mayor en mujeres misquitas de Plaplaya, Gracias a Dios / Prevalence of major depression among Miskito women at Plaplaya, Gracias a Dios

Antecedentes: En Honduras no existen estudios sobre depresión mayor en los grupos poblacionales étnicos. El objetivo de este estudio fue determinar la prevalencia de depresión mayor y factores relacionados en mujeres mayores de 18 años de Plaplaya, Gracias a Dios, en la costa misquita hondureña. Sujetos y Métodos: Estudio descriptivo transversal realizado entre enero 2009 y enero 2010 en la población total femenina de Plaplaya. Entre julio y agosto, una vez obtenido el consentimiento informado, se utilizó una encuesta estructurada para recolectar información sociodemográfica y antecedentes, y el instrumento PHQ9 (Patient Health Questionnaire 9) para identificar depresión mayor. Resultados: Se encuestaron 84 mujeres, identificando cinco casos, para una prevalencia de depresión mayor de 6% (IC95% 2.2-13.9). El grupo de edad 18-30 años fue el predominante (52.4%), el 92.9% sabía leer y escribir y 57.2% tenía una pareja estable (casadas yen unión libre). El 53.6% tenía al menos un hijo <10 años. El 17.9% y 2.4% afirmaron haber consumido alcohol y drogas (marihuana y cocaína) en los últimos 6 meses, respectivamente. El 27.4% refirió comportamientos violentos en la familia y 44.0% refirió padecer alguna enfermedad. Se determinó que edad >50 años (p=0.002, OR=27.6, IC95% 2.4-721.9) y escolaridad <6 años (p=0.001) se asociaron a depresión. Todas las pacientes depresivas refirieron dificultad para desempeñar sus labores (p=0.00006). Conclusión: La depresión es un trastorno psiquiátrico universal que se presenta en los diferentes grupos étnicos con variaciones en su caracterización epidemiológica. Se recomienda a la Secretaría de Salud abordar el problema de depresión en estas poblaciones minoritarias.

Major Depressive Disorder: Part-II -Comorbid Anxiety Disorders.

Objective: To demonstrate that Anxiety Disorder comorbidity is reflection of underlying common risk factors (Anxiety proneness) in Major Depressive Disorder patients and may not be a separate disorder. We hypothesized that “Anxious personality traits or disorders under stress take the form of state that is Anxiety Disorders”. Methods:36 indoor patients of psychiatry ward of tertiary level services, out of total 168 admitted patients from Ist January 2008 to 31st Dec. 2008 diagnosed as Major Depressive Disorder (as per DSMIV TR). Socio-demographic data on a self-designed Performa, Montgomery Asberg’s Depression Rating Scale (MADRS), Hamilton Anxiety rating scale (HARS) and Presumptive Stressful Life Event Scale (PSLE) were applied to these patients and they were observed every alternate day till discharge. International Personality Disorder Examination (IPDE) was applied on their third follow-up visit, which ranged from 6 to8 weeks. Results: High level of co-existence of Anxiety disorder 29(80.5%) in the study sample, 11 patients (30.55%) of Major Depressive Disorder had personality disorder level of psychopathology and 18(50%) patient of Major Depressive Disorder had double or more personality traits psychopathology and there were 7(19.45%) patients of Major Depressive Disorder had only single trait personality psychopathology. Conclusion: This work support the gene environmental diathesis where vulnerable person under stress develop Axis I disorder which are considered currently as co morbid disorders.

Prevalência de transtorno depressivo maior em centro de referência no tratamento de hipertensão arterial / Prevalence of major depressive disorders in a reference center for the treatment of hypertension

OBJETIVO: Investigar a prevalência de transtorno depressivo maior em pacientes hipertensos matriculados em um centro de referência universitário para tratamento de hipertensão arterial e fatores de risco cardiovascular. MÉTODOS: Estudo transversal, descritivo, em amostra aleatória representativa, obtida de forma sistemática, de pacientes em atendimento contínuo na Liga de Hipertensão Arterial da Universidade Federal de Goiás. Aplicou-se o Inventário de Depressão de Beck para rastreamento de sintomas depressivos e a Entrevista Estruturada para o Manual de Diagnóstico e Estatística das Perturbações Mentais - Transtornos do Eixo I para avaliação diagnóstica de transtorno depressivo maior. Foram constituídos um grupo com pacientes portadores de depressão maior, denominado grupo-estudo, e um grupo com pacientes não-portadores de depressão maior, denominado grupo-controle. Avaliou-se variáveis sociodemográficas, pressão arterial e bioquímica sangüínea no momento da coleta de dados. RESULTADOS: Foram entrevistados 285 pacientes, tendo sido encontrada prevalência de 20 por cento de depressão maior na população investigada. A idade média foi significativamente menor para o grupo-estudo, com predomínio do sexo feminino. A prática de atividade física regular foi também significativamente menor entre os pacientes do grupo-estudo, que também apresentaram valores mais elevados de pressão arterial diastólica e de colesterolemia. CONCLUSÕES: Foi encontrada uma prevalência de transtorno depressivo maior em pacientes hipertensos superior àquela encontrada na população geral. Isso aponta para uma necessidade de maior atenção ao diagnóstico dos transtornos depressivos em pacientes hipertensos em atendimento primário e ambulatorial.

OBJECTIVE: To investigate the prevalence of major depression disorders in hypertensive patients enrolled in a university reference center for treatment of hypertension and other cardiovascular risk factors. METHODS: Cross-sectional, descriptive study of a representative randomized sample of patients, obtained according to a systematic protocol, among individuals enrolled for continuous treatment at the Hypertension League of Universidade Federal de Goiás. The Beck Depression Inventory was administered to detect depressive symptoms, and the Structured Clinical Interview for the Diagnostic and Statistical Manual of Mental Disorders for diagnostic classification of major depressive disorders. Two groups were formed, one with patients with major depressive disorder, called study group, and another with patients without major depression, called control group. Sociodemographic variables, blood pressure and plasma biochemistry were evaluated at the time of data collection. RESULTS: A total of 285 patients were evaluated and results indicated a 20 percent prevalence of major depression in the population included in the study. Mean age was significantly lower for the study group, in which female patients were predominant. Regular physical activity was significantly lower among patients in the study group, and higher diastolic blood pressure values as well as cholesterolemia were also found in this group. CONCLUSIONS: These results show a higher prevalence of major depressive disorder among these hypertensive patients, compared with the general population. More attention should be paid to establishing an adequate diagnosis for depressive disorders in hypertensive patients, both in primary care facilities and in outpatient clinics.

Alteraciones neuro-funcionales en trastornos del ánimo que cursan con conductas auto-mutilatorias: estudio de perfusión regional cerebral a partir de la técnica de Neuro-SPECT Tc99-HMPAO / Neuro functional alterations in mood disorders with self-injurious behavior: study of regional cerebral perfusion through Tc-99m HMPAO NeuroSPECT

Se reportan los hallazgos encontrados a partir de NeuroSPECT en trastornos del ánimo, incluyendo trastorno bipolar, depresión mayor y auto-mutilación. Se compararon los resultados de una muestra de 29 pacientes con trastorno afectivo en espectro bipolar complicado con conductas auto-mutilatorias, un grupo de 20 pacientes bipolares sin auto-mutilación y 22 pacientes depresivos sin auto-mutilación. Dentro de los hallazgos destaca la asociación entre trastornos del ánimo y auto-mutilación con hiper-perfusión talámica bilateral en el segmento dorso-ventral-anterior, asociado a hipo-perfusión en corteza peri-límbica (áreas 32, 24 y 23 de Brodmann). Los múltiples reportes que relacionan, tanto en animales como en humanos, las conductas auto-mutilatorias con fenómenos de hipo-algesia, anestesia o disestesias, permiten hipotetizar la participación de una disfunción en circuitos tálamo-peri-límbicos asociados a vías nocioceptivas y a conciencia somato-psíquica y su relación con fenómenos auto-mutilatorios.

We report NeuroSPECT findings in mood disorders, including bipolar disorder, major depression and self-mutilation. We compare results in 29 patients with bipolar disorder complicated by self-mutilation, a group of 20 patients with bipolar disorder uncomplicated and 22 patients with mayor depression uncomplicated by self-mutilation. Among the NeuroSPECT findings we report the association of mood disorders and self-mutilation with hyperperfusion of the anterior-dorsal-ventral segment of both thalami concomitant with hypoperfusion in perilimbic cortex, namely areas 32, 24 (anterior cingulate gyrus) and 23 of Brodmann. Multiple reports in the literature relate both, in animals and man, self-mutilation with phenomena of hypoalghesia, anesthesia, or dysestesias and are the basis for our hypothesis linking dysfunction of limbic-thalamic circuits, associated with nocioceptive fibers, somato-psychic consciousness and self-mutilation phenomena.

Neuro-cognitive functions in patients of major depression.

Earlier studies have shown conflicting results regarding impairment of executive functions in patients of major depression. In the present study, subjects were divided into following groups-Group 1 (19 Males & 11 females, age 18-45 years) consisting of patients of major depression diagnosed on the basis of DSM IV criteria and Group 2 (20 Males & 10 females, age 18-45 years) consisting of healthy subjects who had been screened for any sub-psychiatric illness by standardized hindi version of Goldberg's General Health Questionnaire (G.H.Q.). All the Group 1 & Group 2 subjects were rated on Hamilton Rating Scale for Depression (HAM-D) and then administered Neuro-cognitive test battery consisting of Letter Cancellation test, Trail Making test 'A' & 'B', Ruff Figural Fluency test, Forward & Reverse Digit Span test for assessing following cognitive domains: Attention span, visuo-motor scanning, short term memory and executive functions like working memory, information manipulation, set-shifting strategy analysis etc. Results showed significant impairment on all the studied neuro-cognitive parameters in Group 1 subjects as compared to Group 2 subjects, which demonstrate significant impairment of attention, visuomotor speed, immediate verbal memory, short-term retentive capacity and executive functions (strategic planning, attentional set shifting and working memory) in patients of major depression. It may probably be due to the disruption of dorso-lateral prefrontal cortex (dlpfc) and orbito-frontal networks in patients of major depression.
