RESUMO

OBJECTIVE: To summarize current evidence regarding testosterone treatment for women with low sexual desire. MATERIALS AND METHODS: The Female Endocrinology and Andrology Department of the Brazilian Society of Endocrinology and Metabolism invited nine experts to review the physiology of testosterone secretion and the use, misuse, and side effects of exogenous testosterone therapy in women, based on the available literature and guidelines and statements from international societies. RESULTS: Low sexual desire is a common complaint in clinical practice, especially in postmenopausal women, and may negatively interfere with quality of life. Testosterone seems to exert a positive effect on sexual desire in women with sexual dysfunction, despite a small magnitude of effect, a lack of long-term safety data, and insufficient evidence to make a broad recommendation for testosterone therapy. Furthermore, there are currently no testosterone formulations approved for women by the relevant regulatory agencies in the United States, Brazil, and most other countries, and testosterone formulations approved for men are not recommended for use by women. CONCLUSION: Therefore, testosterone therapy might be considered if other strategies fail, but the risks and benefits must be discussed with the patient before prescription.

RESUMO

INTRODUCTION: The prevalence of obesity has grown exponentially over the last several decades. Research has linked male obesity to changes in the gonadal axis, which can induce functional hypogonadism. Bariatric surgery provides sustained weight loss and metabolic improvement. This was a retrospective cohort study to evaluate the male gonadal axis and metabolic profiles of obese individuals during the bariatric pre- and post-operative periods while comparing them to a normal body mass index (BMI) group. METHODS: Twenty-nine obese men, who underwent bariatric surgery between 2012 and 2016 at the Federal University of Santa Catarina Hospital and a control group (CG) of 29 age-matched men with normal BMI, were analyzed. Bariatric pre- and 6-month post-operative data were compared with the CG. RESULTS: The study group (G1) presented an average age, weight, and BMI of 42.8 ± 9.5 years, 155.2 ± 25.8 kg, and 50.6 ± 7.1 kg/m2, respectively. The pre-operative total testosterone (TT) G1 values were different from the CG (229.5 ± 96.4 versus 461.5 ± 170.8 ng/dL, p < 0.01). Bariatric surgery promoted a statistically significant improvement in weight, TT, and metabolic profiles in surgical patients. CONCLUSION: Functional hypogonadism is prevalent in obese men, and we must be aware of this diagnosis. Although studies defining the best diagnostic parameters and indication of adequate hormone replacement therapy are lacking, an increase in TT levels during the first 6 months after bariatric surgery was identified in our study. Previous studies have shown that gonadal function can normalize after metabolic improvement.

RESUMO

Chronic metabolic alterations may represent a risk factor for the development of cognitive impairment, dementia, or neurodegenerative diseases. Hyperglycemia and obesity are known to imprint epigenetic markers that compromise the proper expression of cell survival genes. Here, we showed that chronic hyperglycemia (60 days) induced by a single intraperitoneal injection of streptozotocin compromised cognition by reducing hippocampal ERK signaling and by inducing neurotoxicity in rats. The mechanisms appear to be linked to reduced active DNA demethylation and diminished expression of the neuroprotective transcription factor REST. The impact of the relationship between adiposity and DNA hypermethylation on REST expression was also demonstrated in peripheral blood mononuclear cells in obese children with reduced levels of blood ascorbate. The reversible nature of epigenetic modifications and the cognitive impairment reported in obese children, adolescents, and adults suggest that the correction of the anthropometry and the peripheral metabolic alterations would protect brain homeostasis and reduce the risk of developing neurodegenerative diseases.

RESUMO

Traumatic brain injury (TBI) is a worldwide core public health problem affecting mostly young male subjects. An alarming increase in incidence has turned TBI into a leading cause of morbidity and mortality in young adults as well as a tremendous resource burden on the health and welfare sector. Hormone dysfunction is highly prevalent during the acute phase of severe TBI. In particular, investigation of the luteinizing hormone (LH) and testosterone levels during the acute phase of severe TBI in male has identified a high incidence of low testosterone levels in male patients (36.5-100%) but the prognostic significance of which remains controversial. Two independent studies showed that normal or elevated levels of LH levels earlier during hospitalization are significantly associated with higher mortality/morbidity. The association between LH levels and prognosis was independent of other predictive variables such as neuroimaging, admission Glasgow coma scale, and pupillary reaction. The possible mechanisms underlying this association and further research directions in this field are discussed. Overall, current data suggest that LH levels during the acute phase of TBI might contribute to accurate prognostication and further prospective multicentric studies are required to develop more sophisticated predictive models incorporating biomarkers such as LH in the quest for accurate outcome prediction following TBI. Moreover, the potential therapeutic benefits of modulating LH during the acute phase of TBI warrant investigation.

RESUMO

Abstract A previously healthy 24 yo male presented with a two-month history of epigastric pain, nausea, vomiting, fatigue and malaise. He reported abuse of different substances, including an injectable veterinary vitamin compound, which contains high doses of vitamin A, D and E, and an oily vehicle that induces local edema and enhances muscle volume. Serum creatinine was 3.1 mg/dL, alanine transaminase 160 mg/dL, aspartate transaminase 11 mg/dL, total testosterone 23 ng/dL, 25-OH-vitamin D >150 ng/mL (toxicity >100), 1,25-OH-vitamin D 80 pg/mL, vitamin A 0.7 mg/dL, parathormone <3 pg/mL, total calcium 13.6 mg/dL, 24-hour urinary calcium 635 mg/24h (RV 42-353). A urinary tract ultrasound demonstrated signs of parenchymal nephropathy. The diagnosis was hypercalcemia and acute renal failure secondary to vitamin D intoxication. He was initially treated with intravenous hydration, furosemide and prednisone. On the fifth day of hospitalization a dose of pamidronate disodium was added. The patient evolved with serum calcium and renal function normalization. Thirty days later he presented normal clinical and laboratory tests, except 25-OH-vitamin D that was persistently increased (107 ng/mL), as it may take several months to normalize. This case report is a warning of the risks related to the use of veterinary substances for aesthetics purposes.


Resumo Um paciente de 24 anos do sexo masculino, previamente hígido, apresentou-se com uma história de dois meses de dor epigástrica, náuseas, vômitos, fadiga e mal-estar. Ele relatava abuso de diferentes substâncias, incluindo um composto vitamínico veterinário injetável contendo altas doses de vitamina A, D e E, e um veículo oleoso que induz edema local com aumento de volume muscular. A creatinina sérica estava 3,1 mg/dL, alanina transaminase 160 mg/dL, aspartato transaminase 11 mg/dL, testosterona total 23 ng/dL, 25-OH-vitamina D > 150 ng/mL (toxicidade > 100), 1,25-OH-vitamina D 80 pg/mL, vitamina A 0,7 mg/dL, paratormônio < 3 pg/mL, cálcio total 13,6 mg/dL, cálcio urinário de 24h 635 mg/24h (VR 42-353). Uma ultrassonografia do trato urinário demonstrou sinais de nefropatia parenquimatosa. O diagnóstico foi hipercalcemia e insuficiência renal aguda secundária a intoxicação por vitamina D. Ele foi tratado inicialmente com hidratação intravenosa, furosemida e prednisona. No quinto dia de hospitalização uma dose de pamidronato dissódico foi adicionada. O paciente evoluiu com normalização do cálcio sérico e da função renal. Trinta dias depois ele apresentou testes clínicos e laboratoriais normais, exceto a 25-OH-vitamina D que estava persistentemente elevada (107 ng/mL), já que ela pode demorar vários meses para normalizar. Este relato de caso é um alerta aos riscos relacionados ao uso de substâncias veterinárias para fins estéticos.

RESUMO

Resumo Fundamentação: desde o primeiro posicionamento da Sociedade Brasileira de Diabetes (SBD) sobre diabetes e prevenção cardiovascular, em 2014,1 importantes estudos têm sido publicados na área de prevenção cardiovascular e tratamento do diabetes,2 os quais contribuíram para a evolução na prevenção primária e secundária nos pacientes com diabetes. Ferramentas de estratificação de risco mais precisas, novos fármacos hipolipemiantes e novos antidiabéticos com efeitos cardiovasculares e redução da mortalidade, são parte desta nova abordagem para os pacientes com diabetes. O reconhecimento de que o diabetes é uma doença heterogênea foi fundamental, sendo claramente demonstrado que nem todos os pacientes diabéticos pertencem a categorias de risco alto ou muito alto. Um porcentual elevado é composto por pacientes jovens, sem os fatores de risco clássicos, os quais podem ser classificados adequadamente em categorias de risco intermediário ou mesmo em baixo risco cardiovascular. O presente posicionamento revisa as melhores evidências atualmente disponíveis e propõe uma abordagem prática, baseada em risco, para o tratamento de pacientes com diabetes. Estruturação: perante este desafio e reconhecendo a natureza multifacetada da doença, a SBD uniu-se à Sociedade Brasileira de Cardiologia (SBC) e à Sociedade Brasileira de Endocrinologia e Metabolismo (SBEM), e formou um painel de especialistas, constituído por 28 cardiologistas e endocrinologistas, para revisar as melhores evidências disponíveis e elaborar uma diretriz contendo recomendações práticas para a estratificação de risco e prevenção da Doença Cardiovascular (DVC) no Diabetes Melito (DM). As principais inovações incluem: (1) considerações do impacto de novos hipolipemiantes e das novas medicações antidiabéticas no risco cardiovascular; (2) uma abordagem prática, baseada em fator de risco, para orientar o uso das estatinas, incluindo novas definições das metas da Lipoproteína de Baixa Densidade-colesterol (LDL-colesterol) e colesterol não Lipoproteína de Alta Densidade HDL; (3) uma abordagem baseada em evidências, para avaliar a isquemia miocárdica silenciosa (IMS) e a aterosclerose subclínica em pacientes com diabetes; (4) as abordagens mais atuais para o tratamento da hipertensão; e (5) recomendação de atualizações para o uso de terapia antiplaquetária. Esperamos que esta diretriz auxilie os médicos no cuidado dedicado aos pacientes com diabetes. Métodos: inicialmente, os membros do painel foram divididos em sete subcomitês para definirem os tópicos principais que necessitavam de uma posição atualizada das sociedades. Os membros do painel pesquisaram e buscaram no PubMed estudos clínicos randomizados e metanálises de estudos clínicos e estudos observacionais de boa qualidade, publicados entre 1997 e 2017, usando termos MeSH: [diabetes], [diabetes tipo 2], [doença cardiovascular], [estratificação de risco cardiovascular] [doença arterial coronária], [rastreamento], [isquemia silenciosa], [estatinas], [hipertensão], [ácido acetilsalicílico]. Estudos observacionais de baixa qualidade, metanálises com alta heterogeneidade e estudos transversais não foram incluídos, embora talvez tenham impactado no Nível de Evidência indicado. A opinião de especialistas foi usada quando os resultados das buscas não eram satisfatórios para um item específico. É importante salientar que este posicionamento não teve a intenção de incluir uma revisão sistemática rigorosa. Um manuscrito preliminar, destacando recomendações de graus e níveis de evidência (Quadro 1), foi esboçado. Este passo levou a várias discussões entre os membros dos subcomitês, que revisaram os achados e fizeram novas sugestões. O manuscrito foi, então, revisto pelo autor líder, encarregado da padronização do texto e da inclusão de pequenas alterações, sendo submetido à apreciação mais detalhada pelos membros dos comitês, buscando uma posição de consenso. Depois desta fase, o manuscrito foi enviado para a banca editorial e edição final, sendo encaminhado para publicação. Quadro 1 Graus de recomendações e níveis de evidências adotados nesta revisão Grau de recomendação Classe I A evidência é conclusiva ou, se não, existe consenso de que o procedimento ou tratamento é seguro e eficaz Classe II Há evidências contraditórias ou opiniões divergentes sobre segurança, eficácia, ou utilidade do tratamento ou procedimento Classe IIa As opiniões são favoráveis ao tratamento ou procedimento. A maioria dos especialistas aprova Classe IIb A eficácia é bem menos estabelecida, e as opiniões são divergentes Classe III Há evidências ou consenso de que o tratamento ou procedimento não é útil, eficaz, ou pode ser prejudicial Níveis de Evidência A Múltiplos estudos clínicos randomizados concordantes e bem elaborados ou metanálises robustas de estudos clínicos randomizados B Dados de metanálises menos robustas, um único estudo clínico randomizado ou estudos observacionais C Opinião dos especialistas

RESUMO

BACKGROUND: Since the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes. MAIN BODY: The Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy. CONCLUSIONS: Diabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in individuals in the highest risk as well as protection from overtreatment in those at lower risk. Thus, cardiovascular prevention strategies should be individualized according to cardiovascular risk while intensification of treatment should focus on those at higher risk.

RESUMO

Introdução: Deficiência de vitamina D é reconhecida hoje como pandemia e fator de impacto no desenvolvimento de várias doenças, sendo recentemente relacionada à fisiopatologia da obesidade e da síndrome metabólica. Objetivos: Analisar os níveis séricos de vitamina D em pacientes obesos em avaliação pré-operatória para cirurgia bariátrica correlacionando-os com variáveis clínicas, laboratoriais e epidemiológicas. Métodos: Estudo observacional transversal, com 170 pacientes obesos grau 2 e 3 avaliados no ambulatório de cirurgia bariátrica do HU-UFSC em 2013. Foram coletados dados clínicos, epidemiológicos, antropométricos e laboratoriais. Resultados: A média de idade foi de 40 ± 10 anos, sendo a maioria do sexo feminino, caucasiana e habitante do litoral. O peso e o IMC médios foram 126,0 ± 24,2 kg e 48,0 ± 7,1 kg/m² respectivamente. As comorbidades mais prevalentes foram diabetes mellitus tipo 2 (24,7%) e hipertensão arterial sistêmica (55,3%). A média dos níveis de 25(OH)-vitamina D foi de 26,3 ± 8,4 ng/mL. Deficiência e insuficiência de vitamina D foram encontrados em 23,5 e 45,3% dos pacientes, respectivamente. Não houve correlação significativa entre os níveis de vitamina D e as demais variáveis estudadas, exceto o cálcio corrigido para a albumina. Conclusão: Os pacientes obesos em avaliação para cirurgia bariátrica neste serviço apresentam alta prevalência de deficiência/insuficiência de vitamina D. Estes níveis apresentaram correlação negativa estatisticamente significativa com o cálcio sérico corrigido, mas não com as demais variáveis estudadas.


Background: Vitamin D deficiency nowadays is recognized as a pandemic and important factor for development of a variety of diseases. It has been recently related to the physiopathology of obesity and metabolic syndrome. Objectives: To analyze serum levels of vitamin D in obese patients on preoperative evaluation for bariatric surgery and correlate them to clinical, laboratory and epidemiological variables. Methods: Cross-sectional observational study, including 170 patients with grade 2 and 3 obesity evaluated at the obesity outpatient clinic of the University Hospital (HU-UFSC) in 2013. Clinical, epidemiological, anthropometric and laboratory data were collected. Results: Mean age was 40 ± 10 years, the majority was females, Caucasian and living on the coast. Average weight and BMI were 126.0 ± 24.2 kg e 48.0 ± 7.1 kg/m² respectively. The most prevalent comorbidities were type 2 diabetes mellitus (24.7%) and hypertension (55.3%). Mean serum level of 25(OH)-vitamin D was 26.3 ± 8.4 ng/mL. Vitamin D deficiency and insufficiency were found in 23.5 and 45.3% of patients, respectively. There was no significant correlation between serum vitamin D levels and variables analyzed in this study, except albumin-corrected serum calcium. Conclusion: Obese patients evaluated for bariatric surgery in this service present a high prevalence of vitamin D deficiency/insufficiency. These levels were significantly negatively correlated with albumin-corrected serum calcium, but not with the other studied variables.

RESUMO

Mitochondrial respiratory chain complexes enzymatic (MRCCE) activities were successfully evaluated in frozen brain samples. Epilepsy surgery offers an ethical opportunity to study human brain tissue surgically removed to treat drug resistant epilepsies. Epilepsy surgeries are done with hemodynamic and laboratory parameters to maintain physiology, but there are no studies analyzing the association among these parameters and MRCCE activities in the human brain tissue. We determined the intra-operative parameters independently associated with MRCCE activities in middle temporal neocortex (Cx), amygdala (AMY) and head of hippocampus (HIP) samples of patients (n = 23) who underwent temporal lobectomy using multiple linear regressions. MRCCE activities in Cx, AMY and HIP are differentially associated to trans-operative mean arterial blood pressure, O2 saturation, hemoglobin, and anesthesia duration to time of tissue sampling. The time-course between the last seizure occurrence and tissue sampling as well as the sample storage to biochemical assessments were also associated with enzyme activities. Linear regression models including these variables explain 13-17 % of MRCCE activities and show a moderate to strong effect (r = 0.37-0.82). Intraoperative hemodynamic and laboratory parameters as well as the time from last seizure to tissue sampling and storage time are associated with MRCCE activities in human samples from the Cx, AMYG and HIP. Careful control of these parameters is required to minimize confounding biases in studies using human brain samples collected from elective neurosurgery.

RESUMO

INTRODUCTION: Erectile dysfunction (ED) is often reported by patients with epilepsy and may be related to endocrine system abnormalities, side effects of antiepileptic drugs, psychiatric comorbidities, and family or social difficulties. AIMS: This study aimed to identify independent predictor factors for ED in patients with epilepsy. MAIN OUTCOME MEASURES: the five-question form of the International Index of Erectile Function (IIEF-5). METHODS: Independent predictive factors for ED evaluated by the IIEF-5 questionnaire in 36 patients (mean age: 39 years) with focal epilepsy (mean: 6 seizures/month) were identified by multiple linear regression analysis. RESULTS: Eight (21.1%) patients were asymptomatic. Among the symptomatic patients, 11 (28.9%) had mild dysfunction, 10 (26.3%) had moderate dysfunction, and 9 (23.7%) showed severe ED. The multiple linear regression model including family income (B=0.005; p=0.05), education levels in years (B=0.54; p=0.03), depressive symptoms determined by HADS depression subscale (B=-0.49; p=0.03), and prolactin levels (B=-0.45; p=0.07) showed a moderate association (r=0.64) with the IIEF questionnaire and explained 41% (r(2)=0.41) of its variation. CONCLUSIONS: Erectile dysfunction is highly prevalent in patients with focal epilepsies. Education, depressive symptoms, and prolactin levels can predict erectile dysfunction in up to 41% of patients with epilepsy. This preliminary report justifies further efforts to make a large sample size study to identify independent biomarkers and therapeutic targets for ED treatment in patients with epilepsy.

RESUMO

OBJETIVO: Diabetes mellitus é uma doença crônica prevalente, associada a inúmeras complicações. A neuropatia periférica diabética é a mais comum, acometendo 50% dos diabéticos, mas muitas vezes não é diagnosticada. Por cursar com insensibilidade distal e alterações arquiteturais dos pés, predispõe a úlceras, podendo culminar no pé diabético com risco de amputação. O diabetes mellitus é responsável por 70% das amputações de membros, que poderiam ser prevenidas com o diagnóstico precoce da neuropatia periférica diabética. Sugere-se avaliar o grau de neuropatia em diabéticos por meio de escores, visando homogeneizar o diagnóstico, quantificar a prevalência e promover medidas preventivas. MÉTODOS: Realizou-se entrevista, exame físico e coleta de dados de diabéticos atendidos ambulatorialmente, para pontuação e qualificação no Escore de Sintomas Neuropáticos e no Escore de Comprometimento Neuropático, validados na língua portuguesa para avaliar neuropatia periférica diabética, além de análise das características clínicas e epidemiológicas associadas. RESULTADOS: Foram incluídos 116 pacientes, constatando-se neuropatia periférica diabética em 31,9%. Houve correlação significativa de neuropatia periférica diabética coma idade dos pacientes, mas não com as demais variáveis clínicas e laboratoriais. Os pacientes avaliados apresentaram médias de idade de 55±15 anos e tempo de diabetes de 14,8±10,9 anos, sendo predominantemente caucasianos, mulheres e portadores de diabetes mellitus tipo 2. Eram hipertensos 67,2% e 42,2%, obesos. CONCLUSÃO: A prevalência encontrada corrobora a literatura, embora poucos estudos tenham utilizado critérios similares para diagnosticar neuropatia periférica diabética. Empregando os escores padronizados, de baixo custo e fácil aplicação possibilitamos o diagnóstico precoce e embasado dessa entidade, sendo possível, com isso, reduzir a prevalência de graves complicações do pé diabético e disseminar informações a respeito.


OBJECTIVE: Diabetes mellitus is a prevalent chronic disease, associated with numerous complications. Diabetic peripheral neuropathy is the most common, affecting 50% of diabetics, although is often not diagnosed. Presenting with distal numbness and architectural alterations of the feet, it predisposes ulcers and may culminate in diabetic foot at risk for amputation. Diabetes mellitus is responsible for 70% of limb amputations, which could be prevented with early diagnosis of diabetic peripheral neuropathy. This study aims to evaluate the degree of neuropathy in diabetics through validated scores, in order to standardize the diagnosis, quantify the prevalence and promote preventive actions. METHODS: We performed an interview, physical examination and data collection of diabetic outpatients, for rating in the Neuropathy Symptom Score and the Neuropathy Disability Score, validated in Portuguese, to assess diabetic peripheral neuropathy, in addition to analysis of clinical and epidemiological associated characteristics. RESULTS: We included 116 patients and diabetic peripheral neuropathy was found in 31.9%. There was significant correlation diabetic peripheral neuropathy with age, but not with other clinical and laboratory variables. The mean age was 55±15 years, diabetes duration was 14.8±10.9 years and patients were predominantly Caucasian, women and had type 2 diabetes mellitus. Of the patients, 67.2 % were hypertensive and 42.2% obese. CONCLUSION: The prevalence found is supported by previous data, although few studies have used similar criteria to diagnose diabetic peripheral neuropathy. Employing the standard scores, of low cost and easy implementation, we enable early and accurate diagnosis of this condition, allowing to reduce the prevalence of severe diabetic foot complications and spread information about it.

RESUMO

Objective: To evaluate the validity and utility of the Hamilton Rating Scale for Depression (HAM-D), Beck Depression Inventory (BDI), and Hospital Anxiety and Depression Scale (HADS) as screening tools for depression after severe traumatic brain injury (TBI). Methods: Forty-six consecutive survivors of severe TBI were evaluated at a median of 15 months after injury. Receiver operating characteristic (ROC) analysis was performed using HAM-D, BDI, and HADS as predictors, and the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) as gold standard. Results: The area under the curve (AUC) for HAM-D was 0.89, and the optimal cutoff point was 7 (sensitivity 92.9%, specificity 78.1%); for the BDI, the AUC was 0.946 and the optimal cutoff point was 14 (sensitivity 92.3%, specificity 96.7%); for the HADS, the AUC was 0.947 and the optimal cutoff point was 9 (sensitivity 100%, specificity 80.7%); and for the HADS depression subscale, the AUC was 0.937 and the optimal cutoff point was 6 (sensitivity 92.9%, specificity 83.9%). There were no statistically significant differences among the AUCs. Conclusion: Our findings support a high validity and utility for the HAM-D, BDI, and HADS as screening tools for depression in patients with severe TBI, without major changes in standard cutoff points. .

RESUMO

Objective: To evaluate predictors of non-return to work (nRTW) among social, demographic, clinical, and psychiatric variables after severe traumatic brain injury (TBI) in a cohort of Brazilian patients. Methods: Prospective study. Forty-three community-dwelling individuals treated at a Level I trauma center at the time of TBI were evaluated 18 months after trauma. Measures included DSM-IV-TR criteria for personality changes after TBI and Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to assess psychiatric diagnosis. Hospitalization variables included Glasgow Coma Scale scores, pupil examination findings, associated limb trauma, Marshall computed tomography classification, and blood glucose levels. Results: After multiple logistic regression analysis, only the diagnosis of personality changes was found to be independently associated with nRTW, with an adjusted odds ratio of 10.92 (p = 0.02, 95% confidence interval 1.41-84.28). Conclusions: In this study, personality changes were an independent predictor of nRTW after severe TBI. Ways to predict risk factors associated with personality changes after severe brain injury could aid in identification of early and effective interventions that might ease the burden associated with this condition. .
