Burnout e pensamentos suicidas em médicos residentes de hospital universitário

Este estudo objetivou descrever e analisar a prevalência de burnout e pensamentos suicidas em médicos residentes de um hospital público de Goiânia e verificar se há correlação entre os dois. Foi realizada uma investigação por meio de um estudo analítico-descritivo em corte transversal em 72 residentes através do MBI (Malasch Burnout Inventory) e do questionário de suicídio de Paykel. Este estudo foi aprovado pelo Comitê de Ética em Pesquisa do Hospital das Clínicas da Universidade Federal de Goiás sob o Parecer nº 052/2009. Resultados indicam a prevalência de burnout em 18,05% da amostra. Dentre os 13 sujeitos com manifestação de burnout, 61,53% já apresentaram pensamentos suicidas. Dentre os 42 sujeitos com baixo risco para manifestação de burnout, 28,57% já apresentaram pensamentos suicidas. Evidenciou-se correlação entre burnout e pensamentos suicidas, o que torna preciso elaborar programas de prevenção do burnout. Pesquisas nesta área são necessárias para a compreensão do burnout e sua correlação com pensamentos suicidas e outros distúrbios psiquiátricos.

The mental health of graduate students at the Federal University of São Paulo: a preliminary report

We present data regarding the care provided to graduate level health professionals at the mental health center of the Federal University of São Paulo. From September 1996 to September 2003, 146 graduate students (99 in the Master's degree program and 47 in the Doctoral program) were attended. This population was predominantly female (68.5%), with a mean (± SD) age of 28.6 ± 4.42 years, not married (71.9%). Most of the subjects were professionals who had not graduated from the Federal University (78.1%). The students who sought help for psychological and/or psychiatric problems were classified into two categories: situational-adaptive crises and psychopathological crises. The main diagnoses were depression and anxiety disorders (44%) causing 4.5% of the subjects to be temporarily suspended from their graduate studies; 19.2% reported that they had used psychotropic drugs within the previous month, and 47.9% referred to sleep disturbances. Suicidal tendencies were mentioned by 18% of those interviewed. Students with emotional disturbances and academic dysfunctions should be recognized at an early stage, and it is fundamental for them to have access to mental health programs that provide formal, structured and confidential care. Thus, it is important that professors and advisors in graduate programs build a warm and affective learning environment. If we consider the expressive growth in Brazilian scientific production resulting from the implementation of an extensive national system of graduate education, it is important to focus efforts on enhancing and upgrading the mental health care system.

The polymorphism of the serotonin-2A receptor T102C is associated with age

Epidemiological investigations suggest that T102C polymorphism of gene 5-HT2A may be associated with mean life span because diseases and behaviors related to this polymorphism, such as schizophrenia, suicide, aggression, and addiction, may potentially shorten mean life span. A sample of 687 individuals without previous neuropsychiatric disease was genotyped and separated into 3 groups according to their gender and age: 14-45 years old, 46-64 years old and 65-100 years old. Molecular genotyping was performed using the technique of polymerase chain reaction followed by restriction fragment length polymorphism using HpaII restriction enzyme. 5-HT2A genotype frequencies were: TT = 21.5% (148), CC = 16.6% (114) and TC = 61.9% (425) and allele frequencies were T = 52.5% and C = 46.5%. Significant differences were found between mean age of the TT genotype carriers (60.27 ± 12.60 years) and TC genotype carriers (56.80 ± 13.18 years) of T102C polymorphism of gene 5-HT2A (P = 0.026) as well as the age groups (P = 0.012). Carriers of genotype TT were older than the other two genotypes, whereas carriers of genotype CC had an intermediate age compared with TT and CC subjects. The present results demonstrate an association between T102C polymorphism of gene 5-HT2A and age. Our results suggest that T102C polymorphism of gene 5-HT2A is associated with mean life span, and thus this gene becomes a possible candidate for the group of adaptive genes to meat consumption proposed in the literature. Further studies should be conducted in order to elucidate this association.

Plasticity of neutrophils reveals modulatory capacity

Neutrophils are widely known as proinflammatory cells associated with tissue damage and for their early arrival at sites of infection, where they exert their phagocytic activity, release their granule contents, and subsequently die. However, this view has been challenged by emerging evidence that neutrophils have other activities and are not so short-lived. Following activation, neutrophil effector functions include production and release of granule contents, reactive oxygen species (ROS), and neutrophil extracellular traps (NETs). Neutrophils have also been shown to produce a wide range of cytokines that have pro- or anti-inflammatory activity, adding a modulatory role for this cell, previously known as a suicide effector. The presence of cytokines almost always implies intercellular modulation, potentially unmasking interactions of neutrophils with other immune cells. In fact, neutrophils have been found to help B cells and to modulate dendritic cell (DC), macrophage, and T-cell activities. In this review, we describe some ways in which neutrophils influence the inflammatory environment in infection, cancer, and autoimmunity, regulating both innate and adaptive immune responses. These cells can switch phenotypes and exert functions beyond cytotoxicity against invading pathogens, extending the view of neutrophils beyond suicide effectors to include functions as regulatory and suppressor cells.

Randomized controlled trials of serotonin-norepinephrine reuptake inhibitor in treating major depressive disorder in children and adolescents: a meta-analysis of efficacy and acceptability

New generation antidepressant therapies, including serotonin-norepinephrine reuptake inhibitor (SNRIs), were introduced in the late 1980s; however, few comprehensive studies have compared the benefits and risks of various contemporary treatments for major depressive disorder (MDD) in young patients. A comprehensive literature search of PubMed, Cochrane, Embase, Web of Science, and PsycINFO databases was conducted from 1970 to January 2015. Only clinical trials that randomly assigned one SNRI or placebo to patients aged 7 to 18 years who met the diagnostic criteria for major depressive disorder were included. Treatment success, dropout rate, and suicidal ideation/attempt outcomes were measured. Primary efficacy was determined by pooling the risk ratios (RRs) of treatment response and remission. Acceptability was determined by pooling the RRs of dropouts for all reasons and for adverse effects as well as suicide-risk outcomes. Five trials with a total of 973 patients were included. SNRIs were not significantly more effective than placebo for treatment response but were for remission. The comparison of patients taking SNRIs that dropped out for all reasons and those taking placebo did not reach statistical significance. Significantly more patients taking SNRIs dropped out for adverse effects than those taking placebo. No significant difference was found in suicide-related risk outcomes. SNRI therapy does not display a superior efficacy and is not better tolerated compared to placebo in these young patients. However, duloxetine has a potential beneficial effect for depression in young populations, showing a need for further research.

O nefrologista como consultor ante a intoxicação aguda: epidemiologia das intoxicações graves no Rio Grande do Sul e métodos de aumento da depuração renal

Intoxicações acidentais e intencionais constituem- se em fonte significativa de morbimortalidade. Em emergências ou UTIs, frequentemente o Nefrologista é chamado como consultor para auxiliar na indicação de medidas de aumento da depuração renal de agentes tóxicos. Revisamos o emprego de diálise nas intoxicações agudas por medicamentos ou pesticidas, cujo suporte especializado toxicológico foi realizado por telefone pelo Centro de Informação Toxicológica do Rio Grande do Sul (CIT-RS). Avaliamos a correlação entre necessidade de diálise e óbitos em coorte retrospectivo (1998- 2000). Dos 36.055 atendimentos, 337 foram identificados como graves, 245 preenchendo os critérios de inclusão exigidos. A idade média foi 30 ± 18 anos; 53% mulheres. Medicamentos frequentemente envolvidos foram anticonvulsivantes e antidepressivos, entre outros; quanto aos pesticidas, organofosforados, bipiridílicos e glifosato. Métodos de aumento da eliminação incluíram alcalinização urinária (n = 37) e métodos dialíticos. Diálise entre intoxicações severas ocorreu em 4,5% (n = 11), 3,67 procedimentos/ano (1/22,7 relatos de casos severos). No grupo que dialisou, em 91%, a circunstância foi tentativa de suicídio (principalmente fenobarbital e paraquat). Dois casos requereram hemoperfusão (cloranfenicol e paraquat). Óbitos entre pacientes graves não submetidos a diálise ocorreram em 25,6%, versus 36,3% entre dialisados (RR = 0,89; IC 95% = 0,54-1,35). Os achados podem ser explicados pelo poder estatístico associado ao número de procedimentos realizados. O Nefrologista deve estar atento para situações que requerem o emprego de medidas dialíticas, ainda que não necessariamente para substituição renal, mas para aumento da depuração do agente tóxico.

Desesperança, ideação suicida e depressão em pacientes renais crônicos em tratamento por hemodiálise ou transplante

Introdução: Sintomas de desesperança, ideação suicida e depressão influenciam na qualidade e expectativa de vida de doentes renais crônicos. Objetivo: Avaliar se existe diferença nos sintomas de desesperança, ideação suicida e depressão entre pacientes renais crônicos em hemodiálise ou transplantados. Analisamos também se variáveis sociodemográficas como atividade laboral, ter dependentes, sexo e estado civil interferem nesses sintomas. Métodos: Estudo comparativo, de corte transversal, em que 50 pacientes em hemodiálise crônica e 50 transplantados renais, clinicamente estáveis, sem psicopatologias, pareados por sexo e idade, foram selecionados aleatoriamente. Instrumentos -Beck Hopelessness Scale (BHS), Beck Scale for Suicide Ideation (BSI) e Beck Depression Inventory (BDI). Resultados: BHS: 2% de cada grupo tiveram escore > 8 (p = 1,00). BSI: 4% em hemodiálise e 6% dos transplantados tinham escore > 1 (p = 1,00). BDI: 20% em hemodiálise e 12% dos transplantados apresentaram escore > 14 (p = 0,275). Não houve relação entre as variáveis testadas e os sintomas de desesperança e ideação suicida. Não exercer atividade laboral implicou mais sintomas depressivos (escore médio BDI: 10,5 vs. 7,3, p = 0,027). Transplantados de doadores falecidos apresentaram mais sintomas depressivos comparados aos receptores de doadores vivos (escore médio BDI: 11,0 vs. 6,7, p = 0,042). Conclusão: Não houve diferença na intensidade dos sintomas de desesperança, ideação suicida e depressão entre pacientes estáveis em hemodiálise e transplantados. Não exercer atividade laboral e receber transplante de doador falecido levou a mais sintomas depressivos. A prevalência de ideação suicida e sintomas depressivos, nas duas modalidades, merece atenção e indica a necessidade de monitorização e cuidados nesses pacientes.
