RESUMO Objetivo: Análise comparativa da qualidade de vida e funcionalidade dos pacientes submetidos a artrodese de coluna lombar devido a doença degenerativa da coluna lombar. Os autores buscaram correlacionar a influência dos sintomas de ansiedade e depressão antes e após a cirurgia. Métodos: Estudo de coorte prospectivo, que acompanhou 32 pacientes submetidos à artrodese por doença degenerativa da coluna lombar e aplicou os questionários escala visual analógica da dor (EVA), Oswestry Disability Index (ODI), Medical Outcomes Survey Short Form - 36 items (SF-36) e Hospital Anxiety and Depression Scale (HADS). Esses questionários foram aplicados no período pré-operatório e quatro meses após o procedimento. Resultados: Observou-se melhoria nas médias das pontuações das escalas EVA (p < 0,001) e ODI (p < 0,001). No pré-operatório, as variáveis que apresentaram diferença entre pacientes com e sem sintomas ansiosos foram os domínios de SF36 de estado geral de saúde (p = 0,031), aspectos sociais (p = 0,008) e saúde mental (p = 0,035). No pós-operatório, os pacientes sem sintomas de ansiedade demonstraram melhores resultados nos domínios vitalidade (p = 0,004), aspectos sociais (p = 0,001), saúde mental (p < 0,001) e dor (p = 0,011). No pré-operatório, a variável que apresentou diferença entre pacientes com e sem depressão foi o domínio do SF36 de aspectos emocionais (p = 0,022). No pós-operatório os pacientes sem depressão apresentaram melhores resultados nos domínios dor (p = 0,009), estado geral de saúde (p = 0,001), vitalidade (p < 0,001), aspectos sociais (p < 0,001), aspectos emocionais (p = 0,004) e saúde mental (p = 0,001). Conclusão: A artrodese de coluna lombar mostrou-se efetiva na melhoria da dor, lombalgia, capacidade funcional, limitação por aspectos físicos e vitalidade, bem como em aspectos sociais e emocionais. Pacientes sem sintomas ansiosos e depressivos apresentaram melhores resultados nas escalas avaliadas quando comparados com aqueles com sintomas de ansiedade e depressão.

ABSTRACT Objective: Comparative analysis of the quality of life and functionality of patients undergoing lumbar spine arthrodesis due to degenerative lumbar spine disease. The authors sought to correlate the influence of anxious and depressive symptoms before and after surgery. Methods: A prospective cohort study was performed, with 32 patients submitted to arthrodesis due to degenerative lumbar spine disease and the visual analogue pain scale pain questionnaire, the Oswestry Disability Index questionnaire, the Medical Outcomes Survey Short Form questionnaire - 36 items (SF-36), and the Hospital Anxiety and Depression Scale, applied in the preoperative period and four months after the procedure. Results: There was improvement in the mean scores of the visual analogue pain scale (p < 0.001) and the Oswestry Disability Index (p < 0.001). In the preoperative period, the variables that presented a difference between patients with and without anxiety symptoms were the SF-36 domains of general health (p = 0.031), social aspects (p = 0.008), and mental health (p = 0.035). In the postoperative period, patients without anxiety symptoms showed better results in the vitality (p = 0.004), social aspects (p = 0.001), mental health (p < 0.001), and pain (p = 0.011) domains. In the preoperative period, the variable that presented a difference between patients with and without depression was the SF-36 domain of emotional aspects (p = 0.022). In the post-operative period, patients without depression presented better vitality (p < 0.001), social aspects (p < 0.001), emotional aspects (p = 0.004), and mental health results (p = 0.001). Conclusion: Lumbar spine arthrodesis was effective in improving pain, low back pain, functional capacity, limitation due to physical aspects, vitality, and social and emotional aspects. Patients without anxiety and depression symptoms had better results on the scales compared to those with such symptoms.

Objective: To evaluate the relationship between brain damage biomarkers and mortality in the intensive care unit (ICU). Methods: The sample comprised 70 patients admitted to an ICU. Blood samples were collected from all patients on ICU admission, and levels of S100β and neuron-specific enolase (NSE) were determined by ELISA. Results: Acute Physiologic and Chronic Health Evaluation (APACHE II) score was associated with mortality, but NSE and S100β were not associated with this outcome. In contrast, S100β levels were significantly higher in delirious and non-delirious patients who required mechanical ventilation during ICU stay. Conclusion: Levels of brain biomarkers at the time of ICU admission did not predict mortality in critically ill patients.
