Punção aspirativa de linfonodo axilar guiada pela ultrassonografia é eficaz como método de predição de acometimento linfonodal em pacientes com câncer de mama?

OBJETIVO: Avaliar a viabilidade e acurácia diagnóstica da ultrassonografia pré-operatória combinada com biopsia por agulha fina (US-PAAF) e do exame clínico da axila em pacientes com câncer de mama.MÉTODOS: Neste estudo prospectivo 171 axilas de pacientes com câncer de mama foram avaliadas pelo exame clínico e ultrassonografia (US) com e sem biopsia por agulha fina (PAAF). Os linfonodos com espessura cortical maior que 2,3 mm na ultrassonografia foram considerados suspeitos e submetidos a US-PAAF.RESULTADOS: A análise de regressão logística não mostrou correlação estatisticamente significativa entre exame clínico e axilas positivas no exame patológico. Em relação à avaliação axilar com US, o risco de achados anatomopatológicos positivos aumentou 12,6 vezes, valor Kappa de Cohen foi de 0,12 para exame clínico, 0,48 para US e 0,80 para US-PAAF. A acurácia foi de 61,4% para o exame clínico, 73,1% para os US e 90,1% para US-PAAF. Análise Receiver Operating Chracteristics (ROC) mostrou que uma espessura de 2,75 mm cortical correspondeu à mais elevada sensibilidade e especificidade na predição metástase axilar (82,7 e 82,2%, respectivamente).CONCLUSÕES: A US combinada com aspiração por agulha fina é mais precisa que o exame clínico na avaliação do status axilar no pré-operatório em mulheres com câncer de mama. Aquelas que são US-PAAF positivo podem ser direcionadas para esvaziamento linfonodal axilar imediatamente, e somente aqueles que são US-PAAF negativos devem ser considerados para biópsia de linfonodo sentinela.

Contribuição do hiperandrogenismo para o desenvolvimento de síndrome metabólica em mulheres obesas com síndrome dos ovários policísticos

OBJETIVO: Avaliar a contribuição do hiperandrogenismo para o desenvolvimento da síndrome metabólica (SM) em mulheres obesas com ou sem Síndrome dos Ovários Policísticos (SOP). MÉTODOS: Estudo transversal retrospectivo no qual foram incluídas 60 mulheres obesas com fenótipo clássico da SOP - Consenso de Rotterdam - e 70 obesas sem SOP. A SM foi diagnosticada pelos critérios do NCEP-ATP III. A obesidade foi definida pelo índice de massa corpórea e o hirsutismo, pelo Índice de Ferriman-Gallwey (IFG). As dosagens realizadas foram: testosterona total, sulfato de dehidroepiandrosterona (SDHEA), insulina e glicose, colesterol total, HDL e triglicerídios. A resistência insulínica (RI) foi avaliada pelo HOMA-IR e pelo índice de sensibilidade à insulina de Matsuda e De Fronzo. A analise estatística foi realizada com o teste t de Student, teste do χ² e análise de regressão logística multivariada (p<0,05). RESULTADOS: As obesas com SOP apresentaram significativamente maiores valores de IFG (15,4±6,1), circunferência da cintura (105,6±11,4 cm), testosterona (135,8±71,4 ng/dL), SDHEA (200,8±109,2 µg/dL), HOMA-IR (8,4±8,5) e menores valores de ISI (2,0±1,8) quando comparadas às obesas não SOP (3,2±2,1; 101,4±9,2 cm; 50,0±18,2 ng/dL; 155,0±92,7 µg/dL; 5,1±4,7; 3,3±2,7, respectivamente) (p<0,05). A frequência de SM foi significativamente maior nas obesas com SOP (75%) do que nas obesas não SOP (52,8%) (p=0,01). A análise multivariada não demonstrou contribuição das variávies IFG, testoterona total e SDHEA para o desenvolvimento da SM (p>0,05). CONCLUSÃO: Mulheres obesas com SOP apresentam maior frequência de SM quando comparadas às obesas não SOP. O hiperandrogenismo não mostrou influência nesse grupo de mulheres estudadas.

Depressive symptoms and harmful alcohol use in hepatitis C patients: prevalence and correlates

Introduction It is important to understand the characteristics and vulnerabilities of people who have hepatitis C because this disease is currently an important public health problem. The objective of this study was to estimate the prevalence of depressive symptoms and harmful alcohol use in patients with hepatitis C and to study the association between these outcomes and demographic, psychosocial and clinical variables. Methods This cross-sectional, descriptive and analytical study involved 82 hepatitis C patients who were being treated with pegylated interferon and ribavirin at a public university hospital. The primary assessments used in the study were the Alcohol Use Disorders Identification Test and the Beck Depression Inventory. Bivariate analyses were followed by logistic regression. Results The prevalence of depressive symptoms was 30.5% (n=25), and that of harmful alcohol use was 34.2% (n=28). Logistic regression analysis showed that individuals who were dissatisfied with their social support (OR=4.41; CI=1.00-19.33) and were unemployed (OR=6.31; CI=1.44-27.70) were at a higher risk for depressive symptoms, whereas harmful alcohol use was associated with the male sex (OR=6.78; CI=1.38-33.19) and the use of illicit substances (OR=7.42; CI=1.12-49.00). Conclusions High prevalence rates of depressive symptoms and harmful alcohol use were verified, indicating vulnerabilities that must be properly monitored and treated to reduce emotional suffering in this population.

Primary relapse site pattern in women with triple-negative breast cancer

Despite the remarkable improvements in breast cancer (BC) characterization, accurate prediction of BC clinical behavior is often still difficult to achieve. Some studies have investigated the association between the molecular subtype, namely the basal-like BC and the pattern of relapse, however only few investigated the association between relapse pattern and immunohistochemical defined triple-negative breast cancers (TNBCs). The aim of this study was to evaluate the pattern of relapse in patients with TNBC, namely the primary distant relapse site:One-hundred twenty nine (129) invasive breast carcinomas with follow-up information were classified according to the molecular subtype using immunohistochemistry for ER, PgR and Her2. The association between TNBC and distant relapse primary site was analyzed by logistic regression. Using multivariate logistic regression analysis patients with TNBC displayed only 0.09(95% CI: 0.00-0.74; p = 0.02) the odds of, the non-TNBC patients of developing bone primary relapse. Regarding visceral and lymph-node relapse, no differences between in this cohort were found.Though classically regarded as aggressive tumors, TNBCs rarely development primary relapse in bone when compared to non-TNBC, a clinical relevant fact when investigating a metastasis of an occult or non-sampled primary BC.

Frequency and clinical predictors of coronary artery disease in chronic renal failure renal transplant candidates

Background/aims: Cardiovascular diseases are major causes of mortality in chronic renal failure patients before and after renal transplantation. Among them, coronary disease presents a particular risk; however, risk predictors have been used to diagnose coronary heart disease. This study evaluated the frequency and importance of clinical predictors of coronary artery disease in chronic renal failure patients undergoing dialysis who were renal transplant candidates, and assessed a previously developed scoring system. Methods: Coronary angiographies conducted between March 2008 and April 2013 from 99 candidates for renal transplantation from two transplant centers in Sao Paulo state were analyzed for associations between significant coronary artery diseases (>= 70% stenosis in one or more epicardial coronary arteries or >= 50% in the left main coronary artery) and clinical parameters. Results: Univariate logistic regression analysis identified diabetes, angina, and/or previous infarction, clinical peripheral arterial disease and dyslipidemia as predictors of coronary artery disease. Multiple logistic regression analysis identified only diabetes and angina and/or previous infarction as independent predictors. Conclusion: The results corroborate previous studies demonstrating the importance of these factors when selecting patients for coronary angiography in clinical pretransplant evaluation.

Association between sleep quality and quality of life in nursing professionals working rotating shifts

Objective: To analyze the association between sleep quality and quality of life of nursing professionals according to their work schedules. Methods: A prospective, cross-sectional, observational study was conducted between January and December 2010, with 264 nursing professionals, drawn from 989 subjects at Botucatu General Hospital and stratified by professional category. The Pittsburg Sleep Quality Index and the WHOQOL-bref were administered to evaluate sleep quality and quality of life, respectively. Self-reported demographic data were collected with a standard form. Continuous variables were reported as means and standard deviations, and categorical variables were expressed as proportions. Associations were evaluated using Spearman's correlation coefficient. The association of night-shift work and gender with sleep disturbance was evaluated by logistic regression analysis using a model adjusted for age and considering sleep disturbance the dependent variable. The level of significance was p < 0.05. Results: Night-shift work was associated with severe worsening of at least one component of sleep quality in the model adjusted for age (OR = 1.91; 95% CI 1.04; 3.50; p = 0.036). Female gender was associated with sleep disturbance (OR = 3.40; 95% CI 1.37; 8.40; p = 0.008). Quality of life and quality of sleep were closely correlated (R = -0.56; p < 0.001). Conclusions: Characteristics of the nursing profession affect sleep quality and quality of life, and these two variables are associated.

Greater level of physical activity associated with better cognitive function in hemodialysis in end stage renal disease

Patients with chronic kidney disease (CKD) have a lower exercise tolerance and poor functional capacity, carry on a sedentary lifestyle. Another important change found in patients with CKD is cognitive dysfunction. Physical inactivity has been associated with cognitive dysfunction in the general population, but few studies have evaluated this association in CKD. To assess the association between physical activity and cognitive function in patients with CKD on hemodialysis (HD). We evaluated 102 patients undergoing HD. The participants completed the International Physical Activity Questionnaire, which assesses the level of physical activity and the Mini Mental State Examination, used for cognitive screening. Patients were divided into three groups according to their level of physical activity (GI: active/GII: irregularly active/GIII: sedentary). It was applied logistic regression analysis and adopted as outcome variable the presence of cognitive impairment and preserving as independent variables those with a probability of statistical difference between groups of less than 0.1. It was considered statistically significant when p less than 0.05. The groups were similar in age, duration of HD, and smoking. Statistically significant difference regarding race, body mass index, diabetes mellitus, underlying disease and degree of cognitive impairment. Regarding laboratory data, the groups differed in terms of creatinine, glucose, hemoglobin and hematocrit. There was significant association with better physical activity and cognitive function, even adjusting for confounding variables. the highest level of physical activity was associated with better cognitive function in CKD patients undergoing HD.

Self-perception and oral health in pregnant adolescents

To evaluate the oral health indicators by determining the experience of dental caries and periodontal disease and identification of self-perceived oral health status of pregnant adolescents and to assess the association between the studied variables. A transversal study, survey type and survey of the oral health status of 127 adolescents, 10-19 years of age, pregnant, accompanied by the Unified Health System of Araçatuba-SP was performed. The self-perceived oral health and socio-demographic data were recorded using an adapted questionnaire. The oral health statuses were analyzed using the DMFT and CPI indices in accordance with the criteria established by the WHO for epidemiological survey. Descriptive statistical analyzes and the Fisher's exact test with a significance level of 5% was performed, as well as a logistic regression analysis to verify the association between the variables. Of the total, 41.0% reported having satisfactory oral health, while 63.0% believed they had problems with their teeth and gums. The DMFT index was 12.51 (SD = 4.21). The percentage of caries-free was 6.3%, and 91.3% had periodontal problems. A statistically significant association was found between the variables: self-perceived oral health and periodontal disease p = 0.0166 and self-reported gum disease and periodontal disease p = 0.0039. Most patients considered their oral health as poor and reported having dental and gum problems, which can also be observed in the clinical examination since the caries experience of the pregnant women examined was considered high and the symptoms of periodontal disease were observed in most of the volunteers.
