INCREASED OXIDATIVE STRESS IN THE BLOOD OF OSTOMY PATIENTS.

BACKGROUND: Ostomy is a surgical procedure that creates a stoma that aims to construct a new path for the output of feces or urine. The relationship of oxidative stress (OxS) markers in patients with ostomy is still poorly described. OBJECTIVE: The present study was aimed at investigating the changes in oxidative stress parameters in peripheral blood collected from ostomy patients when compared with a healthy control group. METHODS: It was evaluated 29 ostomy patients and 30 healthy control patients. The oxidative stress parameters evaluated were: lipid peroxidation [lipid hydroperoxide (LPO), 8-isoprostane (8-ISO) and 4-hydroxynonenal (4-HNE)], protein oxidation and nitration [carbonyl and 3-nitrotyrosine (3-NT)] and DNA oxidation [8-hydroxy-2'-deoxyguanosine (8-OHDG)] in serum from ostomy patients compared to health controls. RESULTS: The data showed an increase of LPO, 8-ISO, 4-HNE, 3-NT and 8-OHDG in serum collected from ostomy patients when compared to healthy controls. CONCLUSION: The findings support the hypothesis that ostomy triggers the oxidative stress observed in the blood collected from these patients.

RESUMO CONTEXTO: Ostomia é um procedimento cirúrgico que cria um estoma com objetivo de construir um novo caminho para a saída das fezes ou urina. A relação dos marcadores de estresse oxidativo em pacientes ostomizados ainda é pouco descrita. OBJETIVO: O presente estudo tem como objetivo investigar as alterações dos parâmetros de estresse oxidativo em sangue de pacientes ostomizados comparados a controles saudáveis. MÉTODOS: Foram avaliados 29 pacientes ostomizados e 30 controles saudáveis. Os parâmetros de estresse oxidativo avaliados foram: peroxidação lipídica [hidroperóxido de lipídio (LPO), 8-isoprostano (8-ISO) e 4-hidroxinonenal (4-HNE)], oxidação e nitração de proteínas [carbonila e 3-nitrotirosina (3-NT)] e oxidação do DNA [8-hidroxi-2'-desoxiguanosina (8-OHDG)] em soro de pacientes ostomizados comparados a controles saudáveis. RESULTADOS: Os dados mostraram um aumento de LPO, 8-ISO, 4-HNE, 3-NT e 8-OHDG em soro de pacientes ostomizados em comparação a controles saudáveis. CONCLUSÃO: Os achados sustentam a hipótese de que a ostomia desencadeia o estresse oxidativo observado no sangue coletado destes pacientes.

Prevalência de transtornos ansiosos e algumas comorbidades em idosos: um estudo de base populacional / Prevalence of anxiety disorders and some comorbidities in elderly: a population-based study

RESUMO Objetivo Avaliar a prevalência de transtornos ansiosos e fatores associados em uma amostra populacional de idosos do Sul de Santa Catarina. Métodos Estudo transversal com base em dados populacionais, que avaliou 1.021 indivíduos idosos entre 60 e 79 anos. Foram realizadas entrevistas domiciliares para aferição de variáveis sobre transtornos ansiosos, por meio do questionário MINI, dados sociodemográficos, hipertensão arterial sistêmica (HAS), infarto agudo do miocárdio (IAM) e dosagem de colesterol. Resultados As prevalências entre os transtornos ansiosos foram de 22,0% para o transtorno de ansiedade generalizada (TAG); 14,8% para fobia social (FS); 10,5% para transtorno do pânico (TP); e 8,5% para o transtorno obsessivo-compulsivo (TOC). Além disso, 40,5% dos indivíduos apresentaram pelo menos um transtorno de ansiedade. A distribuição dos transtornos foi semelhante nos dois gêneros; TAG foi mais prevalente nos indivíduos de menor escolaridade; TOC foi mais presente em indivíduos casados ou em união estável. Em relação às variáveis clínicas, HAS foi associada à presença de TOC; FS foi associada com IAM; TOC e FS foram associados com HDL > 40 mg/dL. Conclusão Os dados demonstram que os quadros de ansiedade são muito frequentes em idosos da comunidade, se sobrepõem de forma significativa e estão associados a algumas variáveis clínicas cardiovasculares.

ABSTRACT Objective This study evaluated the prevalence of anxiety disorders and associated factors in a population sample of elderly from South of Santa Catarina. Methods Cross-sectional study based on population data, which evaluated 1,021 elderly individuals, between 60 and 79 years. Home interviews were conducted to measure the variables of anxiety disorders, through of the MINI questionnaire, sociodemographic data, systemic arterial hypertension (SAH), acute myocardial infarction (AMI) and serum cholesterol measurements. Results The prevalence among anxiety disorders were 22.0% for generalized anxiety disorder (GAD), 14.8% for social phobia (FS); 10.5% for panic disorder (PD); 8.5% for obsessive-compulsive disorder (OCD), and with only, at least one disorder 40.5%. The distribution of the disorders were similar in both genders, GAD was more prevalent among those with lower education; OCD was more prevalent in individuals who were married or in union stable. In relation to clinical variables, SAH was associated with the presence of OCD; FS was associated with AMI; FS and OCD were associated with HDL > 40 mg/dL. Conclusion The data demonstrate that anxiety conditions are very common in older adults, significantly overlap and are associated with cardiovascular clinical variables.

Anxiety disorders are associated with quality of life impairment in patients with insulin-dependent type 2 diabetes: a case-control study

Objective: To assess the presence of anxiety disorders and quality of life in patients with insulin-dependent type 2 diabetes. Methods: Case-control study of 996 patients with type 2 diabetes and 2,145 individuals without diabetes. The sole inclusion criterion for the case group was insulin-dependent type 2 diabetes. We compared the case and control groups for sociodemographic variables, laboratory and clinical data, and presence of anxiety disorders. Quality of life was evaluated using the WHOQOL-BREF instrument, and the prevalence of anxiety disorder was evaluated by the Mini International Neuropsychiatric Interview (MINI). Results: Patients with diabetes had a higher prevalence of generalized anxiety disorder, panic disorder, and obsessive-compulsive disorder. The presence of these disorders in combination with type 2 diabetes was associated with worse quality of life in the physical, social, psychological, and environmental domains. Conclusions: This study demonstrates the importance of diagnosing and treating anxiety disorders in patients with diabetes, so as to prevent more serious complications associated with these comorbidities. .

Acute brain inflammation and oxidative damage are related to long-term cognitive deficits and markers of neurodegeneration in sepsis-survivor rats.

Survivors from sepsis present long-term cognitive deficits and some of these alterations resemble the pathophysiological mechanisms of neurodegenerative diseases. For this reason, we analyzed beta-amyloid peptide (Aß) and synaptophysin levels in the brain of rats that survived from sepsis and their relation to cognitive dysfunction and to acute brain inflammation. Sepsis was induced in rats by cecal ligation and puncture, and 30 days after surgery, the hippocampus and prefrontal cortex were isolated just after cognitive evaluation by the inhibitory avoidance test. The immunocontent of Aß and synaptophysin were analyzed by Western blot analysis. Aß increased and synaptophysin decreased in septic animals both in the hippocampus and prefrontal cortex concurrent with the presence of cognitive deficits. Prefrontal levels of synaptophysin correlated to the performance in the inhibitory avoidance. Two different treatments known to decrease brain inflammation and oxidative stress when administered at the acute phase of sepsis decreased Aß levels both in the prefrontal cortex and hippocampus, increased synaptophysin levels only in the prefrontal cortex, and improved cognitive deficit in sepsis-survivor animals. In conclusion, we demonstrated that brain from sepsis-survivor animals presented an increase in Aß content and a decrease in synaptophysin levels and cognitive impairment. These alterations can be prevented by treatments aimed to decrease acute brain inflammation and oxidative stress.

Increased prevalence of mood disorders and suicidal ideation in type 2 diabetic patients.

This study evaluated the association of mood disorders, suicidal ideation and the quality of life in patients with type 2 diabetes. We used a case-control study employing 996 patients suffering with type 2 diabetes (using insulin for over 1 year), and 2.145 individuals without diabetes. The groups were then used to evaluate the presence of different mood disorders and suicidal ideation, beyond quality of life. In addition to this, fasting glucose and glycosylated hemoglobin (Hb1C) were also evaluated. The data were analyzed using the Pearson chi-squared test, logistic regression, ANCOVA and Student's t-tests. We showed an association between type 2 diabetes and depressive episodes (adjusted OR = 1.8, CI 95 % 1.7-2.0, p < 0.001), recurrent depressive episodes (adjusted OR = 2.4, CI 95 % 2.2-2.6, p < 0.001), dysthymia (adjusted OR = 5.2, CI 95 % 4.9-5.5, p < 0.001), mood disorder with psychotic symptoms (adjusted OR = 2.5, CI 95 % 1.5-3.4, p < 0.001) and suicidal ideation (adjusted OR = 3.6, CI 95 % 2.5-4.8, p < 0.001, light; adjusted OR = 4.6, CI 95 % 1.5-7.7, p < 0.01, moderate and severe). The recurrent depression (OR = 1.3, CI 95 % 1.1-1.7, p < 0.05) and psychotic symptoms (OR = 4.1, CI 95 % 1.1-15.1, p < 0.05) were associated with higher levels of Hb1C. Dysthymia was associated with high blood glucose (OR = 1.6, CI 95 % 1.1-2.5, p < 0.05). Patients had lower mean scores in the following domains: physical [36.5 (13.6) × 56.0 (4.9), p < 0.001)], psychological [42.6 (8.6) × 47.9 (8.6), p < 0.001] and environmental [40.0 (8.6) × 49.3 (8.3), p < 0.001], but had higher scores in the area of social relations [50.2 (16.9) × 35.7 (27.9), p < 0.001]. The data demonstrated a worse quality of life, a high comorbidity of type 2 DM with depressive disorders and suicidal ideation. In addition, the poor control of DM is associated with the severity of mood disorders.

Autonomia e empoderamento do Enfermeiro atuante na área hospitalar / Autonomy and empowerment of the operating Nurse in the hospital area

Estudo qualitativo descritivo, desenvolvido em um hospital da região do sul de Santa Catarina, com oito enfermeiros que assumem funções gerenciais, objetivando desvelar o exercício da autonomia e empoderamento deste profissional. Foi realizada entrevistas com perguntas semi-estruturadas no mês de junho de 2011. A análise dos dados foi realizada pela analise de conteúdo proposta por Minayo. Com relação à concepção de autonomia surge a liberdade de idéia e expressão; possibilidade de delegar “mandar” e tomada de decisão a partir da habilidade e competência. Nas concepções de empoderamento, o poder e o abuso de poder são destacados. Quando questionados sobre se exercem autonomia profissional, afirma ter autonomia regulada, punitiva, administrativa organizacional e no processo do cuidado. Os enfermeiros entrevistados deixam as sugestões de como profissional serem mais independentes da categoria médica e utilização mais otimizada da legislação...
