    PURPOSE: To evaluate the accuracy of sonographic endometrial thickness and hysteroscopic characteristics in predicting malignancy in postmenopausal women undergoing surgical resection of endometrial polyps. METHODS: Five hundred twenty-one (521) postmenopausal women undergoing hysteroscopic resection of endometrial polyps between January 1998 and December 2008 were studied. For each value of sonographic endometrial thickness and polyp size on hysteroscopy, the sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) were calculated in relation to the histologic diagnosis of malignancy. The best values of sensitivity and specificity for the diagnosis of malignancy were determined by the Receiver Operating Characteristic (ROC) curve. RESULTS: Histologic diagnosis identified the presence of premalignancy or malignancy in 4.1% of cases. Sonographic measurement revealed a greater endometrial thickness in cases of malignant polyps when compared to benign and premalignant polyps. On surgical hysteroscopy, malignant endometrial polyps were also larger. An endometrial thickness of 13 mm showed a sensitivity of 69.6%, specificity of 68.5%, PPV of 9.3%, and NPV of 98% in predicting malignancy in endometrial polyps. Polyp measurement by hysteroscopy showed that for polyps 30 mm in size, the sensitivity was 47.8%, specificity was 66.1%, PPV was 6.1%, and NPV was 96.5% for predicting cancer. CONCLUSIONS: Sonographic endometrial thickness showed a higher level of accuracy than hysteroscopic measurement in predicting malignancy in endometrial polyps. Despite this, both techniques showed low accuracy for predicting malignancy in endometrial polyps in postmenopausal women. In suspected cases, histologic evaluation is necessary to exclude malignancy.356243248Anastasiadis, P.G., Koutlaki, N.G., Skaphida, P.G., Galazios, G.C., Tsikouras, P.N., Liberis, V.A., Endometrial polyps: Prevalence, detection, and malignant potential in women with abnormal uterine bleeding (2000) Eur J Gynaecol Oncol., 21 (2), pp. 180-183Clevenger-Hoeft, M., Syrop, C.H., Stovall, D.W., van Voorhis, B.J., Sonohysterography in premenopausal women with and without abnormal bleeding (1999) Obstet Gynecol., 94 (4), pp. 516-520Goldstein, S.R., Zeltser, I., Horan, C.K., Snyder, J.R., Schwartz, L.B., Ultrasonography-based triage for perimenopausal patients with abnormal uterine bleeding (1997) Am J Obstet Gynecol., 177 (1), pp. 102-108Nagele, F., O'Connor, H., Davies, A., Badawy, A., Mohamed, H., Magos, A., 2500 outpatient diagnostic hysteroscopies (1996) Obstet Gynecol., 88 (1), pp. 87-92van Bogaert, L.J., Clinicopathologic findings in endometrial polyps (1988) Obstet Gynecol., 71 (5), pp. 771-773Dreisler, E., Stampe Sorensen, S., Ibsen, P.H., Lose, G., Prevalence of endometrial polyps and abnormal uterine bleeding in a Danish population aged 20-74 years (2009) Ultrasound Obstet Gynecol., 33 (1), pp. 102-108Lieng, M., Istre, O., Sandvik, L., Qvigstad, E., Prevalence, 1-year regression rate, and clinical significance of asymptomatic endometrial polyps: Cross-sectional study (2009) J Minim Invasive Gynecol., 16 (4), pp. 465-471Schmidt, T., Breidenbach, M., Nawroth, F., Mallmann, P., Beyer, I.M., Fleisch, M.C., Hysteroscopy for asymptomatic postmenopausal women with sonographically thickened endometrium (2009) Maturitas., 62 (2), pp. 176-178Lee, S.C., Kaunitz, A.M., Sanchez-Ramos, L., Rhatigan, R.M., The oncogenic potential of endometrial polyps: A systematic review and meta-analysis (2010) Obstet Gynecol., 116 (5), pp. 1197-1205Martínez, M.A., Jou, P., Nonell, R., Cardona, M., Alonso, I., Vanrell, J.A., Pólipos endometriales: Riesgo de malignización y correlación clínico-anatómica (2004) Prog Obstet Ginecol., 47 (11), pp. 506-510Antunes Jr., A., Costa-Paiva, L., Arthuso, M., Costa, J.V., Pinto-Neto, A.M., Endometrial polyps in pre-and postmenopausal women: Factors associated with malignancy (2007) Maturitas., 57 (4), pp. 415-421Savelli, L., de Iaco, P., Santini, D., Rosati, F., Ghi, T., Pignotti, E., Histopathologic features and risk factors for benignity, hyperplasia, and cancer in endometrial polyps (2003) Am J Obstet Gynecol., 188 (4), pp. 927-931Lieng, M., Istre, O., Qvigstad, E., Treatment of endometrial polyps: A systematic review (2010) Acta Obstet Gynecol Scand., 89 (8), pp. 992-1002Baiocchi, G., Manci, N., Pazzaglia, M., Giannone, L., Burnelli, L., Giannone, E., Malignancy in endometrial polyps: A 12-year experience (2009) Am J Obstet Gynecol., 201 (5), pp. 462. e1-462. e4Rahimi, S., Marani, C., Renzi, C., Natale, M.E., Giovannini, P., Zeloni, R., Endometrial polyps and the risk of atypical hyperplasia on biopsies of unremarkable endometrium: A study on 694 patients with benign endometrial polyps (2009) Int J Gynecol Pathol., 28 (6), pp. 522-528Ben-Arie, A., Goldchmit, C., Laviv, Y., Levy, R., Caspi, B., Huszar, M., The malignant potential of endometrial polyps (2004) Eur J Obstet Gynecol Reprod Biol., 115 (2), pp. 206-210Ferrazzi, E., Zupi, E., Leone, F.P., Savelli, L., Omodei, U., Moscarini, M., How often are endometrial polyps malignant in asymptomatic postmenopausal women?

    An ecological life table for eggs and nymphs of Diaphorina citri Kuwayama (Hemiptera: Psyllidae) was constructed with data obtained from orange orchards (Citrus sinensis Osbeck) in 2 regions of the State of São Paulo, over 4 generations in the period from XI-2006 to V-2007, comprising spring, summer, and fall seasons. Young growing shoots with D. citri eggs present were identifed, and live individuals were counted until adult emergence. No predatory arthropods were observed in association with D. citri eggs and nymphs during the study. The mean parasitism of fourth- and ffth-instar nymphs by Tamarixia radiata Waterston (Hymenoptera: Eulophidae) was 2.3%. The durations of the egg–adult period were similar among the 4 generations, ranging from 18.0 to 24.7 d (at mean temperatures ranging from 21.6 to 26.0 °C) and followed the temperature requirement models obtained in the laboratory for D. citri. However, survival from the egg to the adult stage for the same period varied considerably from 1.7 to 21.4%; the highest mortalities were observed in the egg and small nymphal (frst- to thirdinstar) stages, which were considered to be key phases for population growth of the pest.Uma tabela de vida ecológica foi construída para ovos e ninfas de Diaphorina citri Kuwayama (Hemiptera: Psyllidae) com dados obtidos em pomares de laranja (Citrus sinensis Osbeck) em 2 regiões do estado de São Paulo, com 4 gerações, no período de novembro de 2006 a maio de 2007, compreendendo as estações de primavera, verão e outono. Ramos jovens em crescimento com a presença de ovos de D. citri foram identificados e os indivíduos vivos foram contados até a emergência dos adultos. Nenhum predador foi observado associado a ovos e ninfas de D. citri durante o estudo. A taxa média de parasitismo de ninfas de quarto e quinto ínstares por Tamarixia radiata Waterson (Hymenoptera: Eulophidae) foi de 2.3%. A duração do período de ovo a adulto foi semelhante entre as quatro gerações, variando de 18.0 a 24.7 dias (com temperaturas médias de 21.6 a 26.0 °C) e seguiram os modelos de exigencias térmicas obtidas em laboratório para D. citri. Todavia, a sobrevivencia de ovo até o estágio adulto variou consideravelmente para o mesmo período, de 1.7 a 21.4%, sendo que as maiores mortalidades foram observadas nos estágios de ovos e ninfas pequenas (de primeiro a terceiro ínstares), as quais foram consideradas fases chaves para o crescimento populacional desta praga.info:eu-repo/semantics/publishedVersio

    To investigate the prevalence of stress urinary incontinence and its associated factors in perimenopause women using a population-based household survey. A descriptive, exploratory cross-sectional population-based study with secondary analysis of a population-based household survey on perimenopause and menopause was conducted among women living in the city of Campinas, Brazil. Through a sampling process, 456 women between 45 and 60 years old were selected. Complaints of urinary incontinence and related risk factors, such as age, socioeconomic status, education level, race, parity, smoking habits, body mass index, previous gynecological surgeries, menopausal status, and hormonal replacement therapy were explored. Data were collected through home interviews using an adapted version of the structured pre-tested questionnaire elaborated by the International Health Foundation, International Menopause Society and the American Menopause Society. Statistical analysis were performed using prevalence rates (CI 95%). Thirty-five percent of the interviewees referred stress urinary incontinence. None of the sociodemographic factors studied was associated to the risk of urinary incontinence. In addition, parity did not significantly change the risk of urinary incontinence. Other factors, such as previous gynecological surgeries, body mass index, and smoking habits, were not associated with the prevalence of stress urinary incontinence. Also, menopausal status and hormonal replacement therapy did not change the risk of stress urinary incontinence. Though there was a high prevalence of stress urinary incontinence among perimenopause women, there was not found any associations with sociodemographic and reproductive factors.35428-3

    O componente florestal inserido em sistemas agroflorestais tem a função de modificar as condições do ambiente, tornando-o mais adequado ao desenvolvimento das espécies em consórcio. A utilização de árvores de rápido crescimento e com potencial de utilização viabiliza o desenvolvimento do sistema como um todo. Este trabalho foi desenvolvido com o intuito de conhecer as relações morfométricas para árvores de Cumaru (Dipteryx spp.) como componente florestal em dois sistemas agroflorestais implantados nos municípios de Belterra e Mojuí dos Campos, no estado do Pará e oferecer subsídios para o manejo da espécie no sistema. O levantamento abrangeu 90 indivíduos de cumaru em diferentes idades produtivas e sistemas de cultivo. Foram coletados dados dendrométricos (diâmetro a altura do peito, altura total, altura da primeira ramificação, comprimento da copa e diâmetro da copa) que geraram variáveis morfométricas (proporção de copa, grau de esbeltez, índice de abrangência, índice de saliência e formal de copa). Os resultados mostraram que há diferenças significativas em relação à morfometria entre os indivíduos de cumaru nas duas áreas estudadas. Concluiu-se que o componente implantado no sistema de Mojuí necessita de maiores intervenções silviculturais
