Abstract Objective: this study aimed to evaluate if there is an association of intake of coffee and its polyphenols with mammographic findings in women treated at a breast care service unit of the Unified Health System (SUS), Brazil. Research methods and procedures: this was a cross-sectional study with 532 women treated at a health service. The participants were divided according to their mammographic reports into two groups: without and with altered findings. Two 24-h dietary recalls were applied and coffee consumption was categorized into three groups (less than 1 cup, 1 to 3 cups, and more than 3 cups). Phenolic acids were determined using the Phenol Explorer program. The intake of polyphenols was calculated by adding the values obtained from the total amount of coffee consumed during the day. The Multiple Source Method (MSM) was applied to analyze the usual intake. Results: of the 532 women, 178 (33.5 %) had altered mammographic findings. The participants' average daily coffee intake was 193.4 mL. No significant association was found between coffee consumption and mammographic findings. However, it was found that the second tertile of polyphenols was a protective factor for breast changes. Conclusion: coffee polyphenols are protective against breast changes in the group evaluated and, thus, can help prevent breast cancer.

Resumen Objetivo: este estudio tuvo como objetivo evaluar si existe una asociación de la ingesta de café y sus polifenoles con los hallazgos mamográficos de mujeres tratadas en una unidad de patología mamaria del Sistema Unificado de Salud (SUS), Brasil. Métodos y procedimientos de investigación: este fue un estudio transversal con 532 mujeres tratadas en un servicio de salud. Las participantes se dividieron de acuerdo con sus informes mamográficos en dos grupos: sin y con hallazgos alterados. Se aplicaron dos registros dietéticos de 24 horas y el consumo de café se clasificó en tres grupos (menos de 1 taza, 1 a 3 tazas y más de 3 tazas). Los ácidos fenólicos se determinaron utilizando el programa Phenol Explorer. La ingesta de polifenoles se calculó sumando los valores obtenidos de la cantidad total de café consumido durante el día. Se aplicó el método de fuentes múltiples (MSM) para analizar la ingesta habitual. Resultados: de las 532 mujeres, 178 (33,5 %) tenían hallazgos mamográficos alterados. La ingesta diaria promedio de café de los participantes fue de 193,4 ml. No se encontró una asociación significativa entre el consumo de café y los hallazgos mamográficos. Sin embargo, se encontró que el segundo tercil de polifenoles era un factor protector para los cambios mamarios. Conclusión: los polifenoles del café son protectores contra los cambios mamarios en el grupo evaluado y, por lo tanto, podrían ayudar a prevenir el cáncer de mama.

Resumen Introducción: el consumo inadecuado de micronutrientes es un problema de salud pública emergente que puede comprometer la salud. Objetivos: evaluar si la calidad de los carbohidratos de la dieta está asociada con el consumo de 13 micronutrientes en una muestra de mujeres monitoreadas por el Sistema Único de Salud de Brasil. Métodos: este estudio transversal incluyó a 648 mujeres monitoreadas por el Sistema Único de Salud de Brasil. La asociación entre la calidad de los carbohidratos de la dieta y la adecuación del consumo de 13 micronutrientes se investigó mediante modelos de regresión logística ajustados por posibles variables de confusión. Resultados: el consumo de micronutrientes aumentó a medida que mejoraba la calidad de los carbohidratos. Los micronutrientes con mayor prevalencia de ingesta inadecuada fueron: vitamina A, magnesio, manganeso y tiamina. Después de los ajustes mediante modelos de regresión logística, las mujeres del tercer tercil del índice de calidad de carbohidratos tenían menos probabilidades de tener un consumo inadecuado de magnesio (odds ratio (OR): 0,29; intervalo de confianza (IC) del 95 %: 0,14-0,59), manganeso (OR: 0,32 ; IC del 95 %: 0,21 a 0,49) y cobre (OR: 0,22; IC del 95 %: 0,12 a 0,37). Conclusiones: la ingesta de una mayor calidad de carbohidratos en la dieta se asocia con una mejor adecuación en el consumo de la mayoría de los micronutrientes en mujeres monitoreadas por el Sistema Único de Salud de Brasil, especialmente magnesio, manganeso y cobre, después del ajuste mediante modelos de regresión.

Abstract Introduction: inadequate consumption of micronutrients is an emerging public health problem that can compromise health. Objectives: to assess whether the quality of dietary carbohydrates is associated with the consumption of 13 micronutrients in a sample of women monitored by the Brazilian Unified Health System. Methods: this cross-sectional study included 648 women monitored by the Brazilian Unified Health System. The association between quality of dietary carbohydrates and adequacy of consumption of 13 micronutrients was investigated using logistic regression models adjusted for potential confounding variables. Results: the consumption of micronutrients increased as the quality of carbohydrates improved. The micronutrients with the highest prevalence of inadequate intake were vitamin A, magnesium, manganese, and thiamine. After adjustments using logistic regression models, women in the third tertile of the carbohydrate quality index were less likely to have an inadequate consumption of magnesium (odds ratio (OR), 0.29; 95 % confidence interval (CI), 0.14-0.59), manganese (OR, 0.32; 95% CI, 0.21-0.49), and copper (OR, 0.22; 95% CI, 0.12-0.37). Conclusions: intake of a higher quality of dietary carbohydrates is associated with improved adequacy in consumption of most micronutrients in women monitored by the Brazilian Unified Health System, especially magnesium, manganese, and copper, after adjustment using regression models.

RESUMO Objetivo: analisar a relação das características anatomopatológicas com o comprometimento axilar em casos de carcinoma ductal invasor. Métodos: estudo transversal de 220 pacientes com câncer de mama, submetidas à mastectomia radical ou quadrantectomia com esvaziamento axilar, oriundos do Serviço de Mastologia da Maternidade Escola Assis Chateaubriand, Ceará, Brasil. Os tumores foram submetidos a processamento histológico e, em seguida, foram determinados os graus histológico (GH), tubular (GT), nuclear (GN), índice mitótico (IM) pela classificação de Scarff-Bloom-Richadson, verificada a presença de invasão angiolinfática (IA) e mensurado o maior diâmetro do tumor (DT). Tais variáveis foram correlacionadas com a presença de metástases axilares. Resultados: a média de idade das pacientes foi 56,81 anos ± 13,28. O tamanho do tumor variou de 0,13 a 22 cm, com média de 2,23cm ± 2,79. Os GH3, GT3 e GN3 prevaleceram: n=107 (48,6%), n=160 (72,7%) e n=107 (48,6%), respectivamente. Os índices mitóticos 1, 2 e 3 apresentaram distribuição homogênea: n=82 (37,2%), n=68 (31%) e n=70 (31,8%), respectivamente. Não foi evidenciada relação do GH, GT e GN com a ocorrência de metástases axilares (p=0,07; p=0,22 e p=0,21). Índices mitóticos 2 e 3 apresentaram relação com a o ocorrência de metástases axilares (p=0,03). Tumores maiores do que 2cm e casos com invasão angiolinfática apresentaram maior índice de metástases axilares (p=0,0003 e p<0,0001). Conclusão: índices mitóticos elevados, tumores com diâmetro maior do que 2cm e presença de invasão angiolinfática apresentaram isoladamente relação com a ocorrência de metástases axilares.

ABSTRACT Objective: to analyze the relation of anatomopathological features and axillary involvement in cases of invasive ductal carcinoma. Methods: this is a cross-sectional study of 220 breast cancer patients submitted to radical mastectomy or quadrantectomy with axilar emptying, from the Mastology Service of the Assis Chateaubriand Maternity School, Ceará, Brazil. We submitted the tumors to histological processing and determined the histological (HG), tubular (TG) and nuclear (NG) grades, and the mitotic index (MI) by the classification of Scarff-Bloom-Richadson, verified the presence of angiolymphatic invasion (AI) and measured the largest tumor diameter (TD). We then correlated these variables with the presence of axillary metastases. Results: the mean patients'age was 56.81 years ± 13.28. Tumor size ranged from 0.13 to 22 cm, with an average of 2.23cm ± 2.79. HG3, TG3 and NG3 prevailed, respectively 107 (48.6%), 160 (72.7%) and 107 (48.6%). Mitotic indexes 1, 2 and 3 presented a homogeneous distribution, respectively 82 (37.2%), 68 (31%) and 70 (31.8%). We observed no relation between the HG, TG and NG with the occurrence of axillary metastases (p=0.07, p=0.22 and p=0.21, respectively). Mitotic indices 2 and 3 were related with the occurrence of axillary metastases (p=0.03). Tumors larger than 2cm and cases that presented angiolymphatic invasion had a higher index of axillary metastases (p=0.0003 and p<0.0001). Conclusion: elevated mitotic indexes, tumors with a diameter greater than 2cm and the presence of angiolymphatic invasion were individuallyassociatedwith the occurrence of axillary metastases.

PURPOSE: To assess the safety and potential equivalence of the use of hemosiderin compared to the Technetium-99 in sentinel lymph node biopsy in human breast cancer. METHODS: Non-random sample of 14 volunteer women diagnosed with breast cancer with primary tumors (T1/T2) and clinically tumor-free axilla were submitted to the identification of sentinel lymph node using hemosiderin obtained from autologous blood injected in the periareolar region 24h before surgery on an outpatient basis. Patients received preoperative subareolar intradermal injection of Technetium-99 in the immediate preoperative period. Patients were submitted to sentinel lymph node biopsy, with incision in the axillary fold guided by Gamma-Probe, dissection by planes until the identification of the point of maximum uptake of Technetium-99, identifying the marked nodes and their colors. All surgical specimens were sent for pathological and immunohistochemical study. RESULTS: The results showed no evidence of side effects and/or allergic and non-allergic reactions in patients submitted to SLNB with hemosiderin. The SLN identification rate per patient was 100%. SLNB identification rate per patient with hemosiderin was the same as that of Technetium, with a concordance rate of 100% between the methods. CONCLUSION: Hemosiderin is a safe dye that is equivalent to Technetium in breast sentinel lymph node biopsy.

OBJETIVO: Definir um modelo experimental para a pesquisa do linfonodo sentinela na vulva de cadelas. MÉTODOS: 0,2 ml de tecnécio diluído em fitato (99mTc) foi injetado por via intradérmica na comissura anterior da vulva. Trinta minutos após a injeção de 99mTc, o mapeamento inguinal foi realizada utilizando uma sonda gama. Após isto, 0,5 ml de corante azul (bleu Patente Guerbet V 2,5%) foram injetados no mesmo lugar. Após 15 minutos, uma incisão inguinal de três centímetros foi feita no ponto de captação máxima seguido de dissecção cuidadosa, guiada através da visualização de um sistema linfático aferente corado em azul que apontava para o linfonodo sentinela (LS). RESULTADOS: Foi observado que em 88% das vezes o LS foi identificado. Não foi encontrada diferença significativa entre a presença ou não de linfonodo sentinela nos lados direito e esquerdo, o que é uma indicação de uma boa consistência do método. Foi observada uma alta (88%) e significativa (χ2 = 12,89 e p = 0,0003) intercessão entre os dois métodos (corante azul e radiação). CONCLUSÃO: O modelo experimental adotado é viável, tornando-se vantajoso na aplicação da associação de Azul Patente e 99mTc.

PURPOSE: This paper aims to study and define the experimental model of sentinel lymph node biopsy of the vulva in bitches. METHODS: 0.2 ml of 99mTc phytate was injected intradermally, using a fine gauge insulin needle in the anterior commissure of the vulva. Thirty minutes after 99mTc injection, the inguinal mapping was performed using a gamma probe. After this, 0.5 ml of blue dye (bleu patenté V Guerbet 2.5%) was injected in the same place. After 15 minutes, a 3 cm long inguinal incision was made at point maximum uptake followed by careful dissection, guided by visualization of a bluish afferent lymphatic system that points to the sentinel lymph node (SLN). RESULTS: It was observed that 88% of SLN were identified. It wasn´t found a significant difference among the presence or not of sentinel lymph node in the sides, which is an indication of a good consistency. It was observed a high (88%) and significant (χ2=12.89 and p=0.0003) intercession between both methods (blue dye and radiation). CONCLUSION: The experimental model adopted is feasible, becoming advantageous in applying the association of Patent blue and 99mTc.

CONTEXTO: A doença de Alzheimer (DA) é a demência de maior prevalência e está associada a alterações cognitivas, comportamentais e funcionais. Entretanto, faz-se necessário esclarecer a influência do agravamento da doença no declínio dessas funções. OBJETIVO: Comparar funções cognitivas específicas, funções motoras e atividades de vida diária (AVD) de pacientes com DA em diferentes estágios da doença. MÉTODOS: Foram avaliadas as funções cognitivas, as funções motoras e as AVD de 74 pacientes com doença de Alzheimer (35 pacientes CDR1; 20 pacientes CDR2; 19 pacientes CDR3). RESULTADOS: A função motora e a independência das AVD apresentam declínio não linear. Enquanto a função motora apresenta maior declínio na fase leve para moderada, as AVD básicas sofrem maior declínio na fase grave da doença. CONCLUSÃO: O declínio motor é mais importante nas fases moderada e grave, associado a valores de perda de capacidade física e risco de quedas. Verifica-se que a perda de independência para realização das AVD instrumentais dos pacientes é muito maior do que o declínio físico e cognitivo avaliado objetivamente nas três fases da doença.

BACKGROUND: Alzheimer's disease (AD) is the most prevalent dementia, being associated with cognitive, behavioral, and functional alterations. However, clarifying the influence of the disease worsening in the decline of these functions is of major relevance. OBJECTIVE: Compare specific cognitive functions, motor functions and activities of daily living (ADL) of AD patients in different stages of the disease. METHODS: Cognitive and motor functions, as well as ADL of 74 AD patients (35 patients CDR1; 20 patients CDR2; 19 patients CDR3) were evaluated. RESULTS: Motor function and independency in the ADL have presented a non-linear decline. While motor function shows a greater decline from the mild to the moderate phase, ADL present a greater decline in the severe stage of the disease. DISCUSSION: Motor function decline is more evident in both moderate and severe stages of AD, associated with losses in physical capacity and increases in risk of falls. The patients' loss of independency to perform instrumental ADL occurs in a non-linear pattern and it is much greater than both physical and cognitive declines when these parameters are objectively evaluated in the three phases of the disease.

OBJECTIVE: The goal of this study was to assess the acute effect of physical exercise on the cognitive function of depressed elderly patients in a dual-task experiment. INTRODUCTION: Physical exercise has a positive effect on the brain and may even act as a treatment for major depressive disorder. However, the effects of acute cardiovascular exercise on cognitive function during and after one session of aerobic training in elderly depressive patients are not known. METHODS: Ten elderly subjects diagnosed with major depressive disorder performed neuropsychological tests during and after a moderate physical exercise session (65-75%HRmax). A Digit Span Test (Forward and Backward) and a Stroop Color-Word Test were used to assess cognitive function. The elderly participants walked on an electric treadmill for 30 minutes and underwent the same cognitive testing before, during, immediately after, and 15 minutes after the exercise session. In the control session, the same cognitive testing was conducted, but without exercise training. RESULTS: The results of the Digit Span Test did not change between the control and the exercise sessions. The results of the Stroop Color-Word Test improved after physical exercise, indicating a positive effect of exercise on cognition. CONCLUSIONS: These data suggest that the cognitive functions of depressed elderly persons, especially attention and inhibitory control, are not impaired during and after an acute session of physical exercise. In contrast, the effect of dual-tasks showed beneficial results for these subjects, mainly after exercise. The dual-task may be a safe and useful tool for assessing cognitive function.

OBJECTIVES: This paper discusses the influence of a para-areolar incision in the upper outer quadrant of the breast on the location of the sentinel lymph node in a canine model. METHODS: The sentinel lymph node was marked with technetium-99, which was injected into the subareolar skin of the cranial breast. After the marker had migrated to the axilla, an arcuate para-areolar incision was performed 2 cm from the nipple in the upper outer quadrant. Patent blue dye was then injected above the upper border of the incision. At the marked site, an axillary incision was made, and the sentinel lymph node was identified by gamma probe and/or by direct visualization of the dye. The agreement between the two injection sites and the two sentinel lymph node identification methods was determined. Our sample group consisted of 40 cranial breasts of 23 adult females of the species Canis familiaris. The data were analyzed by using the McNemar test and by determining the kappa agreement coefficient. RESULT: Our findings showed that in 95% of the breasts, the sentinel lymph node was identified by the injection of technetium-99 m into the subareolar region, and in 82% of the cases, the sentinel lymph node was identified by the injection of patent blue dye above the upper border of the incision. The methods agreed 82% of the time. CONCLUSIONS: Previous para-areolar incisions in the upper outer quadrant did not interfere significantly with the biopsy when the dye was injected above the upper border of the incision.

OBJETIVO: Avaliar e apresentar resultados preliminares de um novo marcador (hemossiderina) para a identificação de linfonodos sentinela mamários em um modelo experimental. MÉTODOS: Durante acompanhamento de dois casos de biópsias excisionais de tumores da mama, no nosso serviço de mastologia, observou-se trajeto pigmentado no quadrante inferior externo daquelas mamas, sugerindo ser marcação cutânea do ducto de drenagem linfática a partir da papila mamária em direção a axila homolateral. Levantamos a hipótese que um derivado sanguíneo (hemossiderina) foi capturado por macrófagos obtendo acesso aos ductos linfáticos em direção à axila. Seis cadelas sem raça definida foram estudadas. Injeção de 0,2 ml de tecnécio foi realizada em ambas as mamas superiores. Após 10 minutos, uma solução de 2,5 ml de sangue hemolizado (hemossiderina) do próprio animal foi injetado no plexo linfático subpapilar da mama esquerda e 2,5 ml de azul patente na mama contralateral concomitantemente e igualmente. Após mais 10 minutos, incisões axilares foram realizadas para a procura, pela coloração e com um gama probe, dos linfonodos sentinela. RESULTADOS: Sete linfonodos sentinela castanhos e radiomarcados foram identificados na axila esquerda. Seis linfonodos sentinela azuis e radiomarcados foram identificados na axila direita. CONCLUSÃO: São apresentados estudos preliminares de um potencial novo marcador para identificação do linfonodo sentinela. Este poderá mudar o uso dos corantes vitais e de seus efeitos adversos em pacientes submetidos à biópsia do linfonodo sentinela.

PURPOSE: To evaluate and present our initial results of a new marker (hemosiderin) for mammary sentinel lymph node identification in an experimental model. METHODS: Skins mapped like a lymphatic duct draining to the axilla in patients submitted to breast biopsy, in our mastology service, stimulated us to try it in an animal model (female dogs). Our theory was that some blood derivate (hemosiderin) was captured by macrophages and accessed the lymphatic ducts in direction to the axilla. Six female dogs of no defined race were studied. We injected 0,2 ml of technetium on both superior mammary glands. After ten minutes, a 2,5 ml solution of hemolized blood (hemosiderin) from the own animal was injected in the subareolar lymphatic plexus on the left superior mammary gland and 2,5 ml of patent blue concomitantly and equally on the contralateral gland. Ten minutes after, incisions on both axilas were made to search, through the lymphatic mapping and a gamma probe, the sentinel lymph nodes. RESULTS: Seven brown sentinel lymph nodes were indentified and also radiomarked on the left axilla. Six blue sentinel lymph nodes were identified and also radiomarked on the right axilla. CONCLUSION: Preliminary studies of a potential new dye for sentinel lymph node identification are presented. It may be the change of the current use of the blue dyes and their severe side-effects on patients submitted to sentinel lymph node biopsies.
