Distress do paciente oncológico: prevalência e fatores associados na opinião de familiares / Distress of cancer patients: prevalence and associated factors in the opinion of family / Angustia de los pacientes con cáncer: prevalencia y factores asociados en la opinión de la familia

Este estudo verificou a prevalência e fatores associados ao distress de pacientes oncológicos, na opinião de familiares. Foram entrevistados 140 familiares responsáveis pelo cuidado de pacientes com câncer. O Termômetro de Distress foi adaptado para uso em familiares. Estes consideraram que 72,9% dos pacientes estavam com distress relacionado a preocupações (80,4%), nervosismo (78,4%), tristeza (74,5%), dor (67,6%), fadiga (67,6%) e problemas com alimentação (57,8%). Modelos de regressão logística hierárquica mostraram que, enquanto familiares do sexo masculino (OR=0,025) e idades mais avançadas (OR=0,006 a 0,059) tiveram menor risco de perceber o distress, indivíduos protestantes, comparados a católicos, tiveram chance 12,77 vezes maior de percebê-lo. Quanto aos fatores associados, nervosismo (OR=10,8) contribuiu significativamente mais com a percepção de distress pelos familiares quando comparado a fadiga (OR=3,38) ou ter plano de saúde privado (OR=2,55). Familiares podem ser grandes aliados na avaliação e acompanhamento do distress de pacientes com câncer.

The study aimed to verify the opinion of family members about distress on cancer patients and the factors associated with it. Interviews with 140 family members of cancer patients were conducted. The Distress Thermometer was adapted to be used with family members. Approximately 72.9% of patients were considered in distress, related to concern (80.4%), nervousness (78.4%), sadness (74.5%), pain (67.6%), fatigue (67.6%) and problems with eating (57.8%). The hierarchical logistic regression models showed that while male (OR=0.025) and older ages (OR=0.006 to 0.059) had lower risk of perceiving the distress, individuals Protestants, compared to Catholics, were 12.77 times more likely to perceive it. About the associated factors, nervousness (OR=10.8) contributed significantly more to the perception of distress for family members when compared to fatigue (OR=3.38) or have private health insurance (OR=2.55). Family can be great allies in the evaluation and monitoring of distress in patients with cancer.

A role for lymphocytes and cytokines on the eosinophil migration induced by LPS

In the present work we review the existing evidence for a LPS-induced cytokine-mediated eosinophil accumulation in a model of acute inflammation. Intrathoracic administration of LPS into rodents (mice, rats and guinea pigs) induces a significant increase in the number of eosinophils recovered from the pleural fluid 24 hr later. This phenomenon is preceded by a neutrophil influx and accompanied by lymphocyte and monocyte accumulation. The eosinophil accumulation induced by LPS is not affected by inhibitors of cyclo or lipoxygenase nor by PAF antagonists but can be blocked by dexamethasone or the protein synthesis inhibitors cycloheximide. Transfer of cell-free pleural wash from LPS injected rats (LPS-PW) to naive recipient animals induces a selective eosinophil accumulation within 24 hr. The eosinophilotactic activity present on the LPS-PW has a molecular weight ranging between 10 and 50 kDa and its effect is abolished by trypsin digestion of the plural wash indicating the proteic nature of this activity. The production of the eosinophilotactic activity depends on the interaction between macrophages and T-lymphacytes and its effect can not be blocked by anti-IL-5 monoclonal antibodies. Accumulated evidence suggest that the eosinophil accumulation induced by LPS is a consequence of a eosinophilotactic cytokine produced through macrophage and T-cell interactions in the site of a LPS-induced inflammatory reaction.
