ABSTRACT Introduction: Pregnancy-related complications may impact women’s reproductive cycle and health through their lives. The objective of this study was to evaluate the sociodemographic, clinical, and obstetric history of women undergoing hemodialysis. Methods: We performed a cross-sectional study in a specialized health facility with four hemodialysis units. Sociodemographic characteristics, clinical and personal history, obstetric and perinatal results of women with pregnancies before hemodialysis were evaluated. Prevalence, bivariate, and logistic regression analyses were performed. Results: We included 208 (87.76%) women. Hypertension was the main cause of chronic kidney disease (CKD) (128 women). Rates of adverse perinatal outcomes, including prematurity, low birth weight, miscarriage, fetal death, and neonatal death, were 19.3%, 14.5%, 25.5%, 12.1%, and 5.3%, respectively. Hypertensive syndromes during pregnancy occurred in 37.0% of women, with 12.5% reporting preeclampsia and 1.4% reporting eclampsia. Up to 1 year after birth, 45.2% of women reported hypertension. Hemodialysis due to hypertension was associated with a history of hypertension during pregnancy (OR 2.33, CI 1.27 – 4.24), gestational hypertension (2.41, CI 3.30 – 4.45), and hypertension up to one year after birth (OR 1.98, CI 1.11 – 3.51). Logistic regression showed that gestational hypertension was independently associated with CKD due to hypertension (aOR 2.76, CI 1.45 – 5.24). Conclusion: Women undergoing hemodialysis due to hypertension were more likely to have gestational hypertension or hypertension up to one year after birth. To delay end-stage renal disease, it is necessary to identify women at risk of kidney failure according to their reproductive history.

RESUMO Introdução: Complicações relacionadas à gestação podem afetar o ciclo reprodutivo e a saúde das mulheres ao longo de suas vidas. Este estudo visou avaliar histórico sociodemográfico, clínico e obstétrico de mulheres em hemodiálise. Métodos: Realizamos estudo transversal em unidade de saúde especializada com quatro unidades de hemodiálise. Avaliou-se características sociodemográficas, histórico clínico e pessoal, resultados obstétricos e perinatais de mulheres com gestações anteriores à hemodiálise. Foram realizadas análises de prevalência, bivariadas e regressão logística. Resultados: Incluímos 208 (87,76%) mulheres. Hipertensão foi a principal causa de doença renal crônica (DRC) (128 mulheres). Taxas de desfechos perinatais adversos, incluindo prematuridade, baixo peso ao nascer, aborto espontâneo, óbito fetal e neonatal, foram de 19,3%, 14,5%, 25,5%, 12,1% e 5,3%, respectivamente. Síndromes hipertensivas durante a gestação ocorreram em 37,0% das mulheres, com 12,5% relatando pré-eclâmpsia e 1,4% relatando eclampsia. Até 1 ano após o parto, 45,2% das mulheres relataram hipertensão. Hemodiálise devido à hipertensão foi associada ao histórico de hipertensão na gestação (OR 2,33; IC 1,27 - 4,24), hipertensão gestacional (2,41; IC 3,30 - 4,45), e hipertensão até um ano após o parto (OR 1,98; IC 1,11 - 3,51). A regressão logística mostrou que hipertensão gestacional foi independentemente associada à DRC devido à hipertensão (ORa 2,76; IC 1,45 - 5,24). Conclusão: Mulheres submetidas à hemodiálise por hipertensão foram mais propensas a apresentar hipertensão gestacional ou hipertensão até um ano após o parto. Para retardar a doença renal em estágio terminal, deve-se identificar mulheres em risco de insuficiência renal de acordo com sua história reprodutiva.

ABSTRACT Mobility and urban planning are challenging tasks for public authorities, especially in densely populated cities. The city of Olinda, Pernambuco-Brazil, faces problems in traffic and access to places, making it necessary to identify new alternatives to improve urban mobility in Olinda. This study presents a decision support model to develop and evaluate new alternatives to do so. In the decision frontend, Value-Focused Thinking was applied to identify objectives and their respective attributes, and to create alternatives based on these objectives. As a result, 69 alternatives were generated, concatenated into 48, and categorized into four groups. Group 1 and Group 2 comprise 30 alternatives that serve the city’s north side; however, they attend to the neighborhoods separately. Group 3 comprises 11 alternatives routes that serve the two areas together, this being the focus of this study, and Group four consists of 7 short-term alternatives. In the decision backend, the FITradeoff for ranking problematic method was applied to evaluate the 11 alternatives of Group 3. The study showed that it would be possible to improve mobility more urgently by making a few improvements to the itinerary on the existing routes. Therefore, the study discusses the possibility of starting to make progress in the urban system of the city by using fewer complex alternatives compared to setting up new routes.

Abstract INTRODUCTION: DENV-2 is the cause of most dengue epidemics worldwide and is associated with severe cases. METHODS: We investigated arboviruses in 164 serum samples collected from patients presenting with clinical symptoms of dengue fever and 152 mosquito pools. RESULTS: We detected the Asian II genotype of DENV-2 in humans and mosquitoes. Our results confirmed the circulation of the Asian II genotype in Brazil, in addition to the prevalent Asian/American genotype. CONCLUSIONS: The detection of Asian II genotype of DENV-2 in mosquito pools collected in a forest park may be related to a spillback event of human dengue virus.

Resumo Objetivo O objetivo deste estudo foi investigar os conhecimentos sobre ganho de peso gestacional (GPG), nutrição, e exercício físico (EF) em gestantes e o quanto elas os colocam em prática. Métodos Estudo transversal realizado no Hospital da Mulher, CAISM, Unicamp, com 61 gestantes acima das 26 semanas gestacionais. Questionários sobre conhecimento de hábitos saudáveis (HS) durante a gestação, dados sociodemográficos, e antecedentes obstétricos foram aplicados. Um guia educacional com conselhos sobre HS durante a gravidez e período pós-parto foi oferecido. Resultados A idade média das mulheres foi de 28,7 ± 6,23 anos, sendo 85% casadas, 32% nulíparas, o índice de massa corporal (IMC) médio antes da gestação foi de 25,4 ± 9,8 kg/m2, e amédia de anos de escolaridade foi de 11,2 ± 3,8. Apenas 61% das mulheres entrevistadas haviam recebido informações prévias sobre o GPG durante o pré-natal e sabiam quantos quilos deveriam ganhar durante a gravidez. Entre as mulheres, 85% sabiam que não precisavam “comer por dois,” e 99% sabiam que o EF tinha benefícios para seu corpo e era seguro para seu bebê. Metade das mulheres praticava EF antes da gravidez, mas apenas 31% continuaram praticando durante a gravidez. Conclusão Apesar de compreender a necessidade de HS durante a gravidez, as mulheres ainda precisam de incentivo para praticar EF durante a gravidez, bem como mais informações sobre o GPG.

Abstract Objective The aim of this study was to investigate the knowledge concerning gestational weight gain (GWG), nutrition, and physical exercise (PE) in pregnant women, and how to put them into practice. Methods A cross-sectional study with 61 pregnant women above 26 weeks of gestation, at the Woman’s Hospital, CAISM, University of Campinas. Questionnaires regarding the knowledge of healthy habits (HH) during pregnancy, sociodemographic data, and previous obstetric outcomes were applied. An educational guide with advice on HH during pregnancy and in the postpartum period was offered. Results The average age of women was 28.7 ± 6.23 years, with 85% of them being married; 32% nulliparous; the average body mass index (BMI) before pregnancy was 25.4 ± 9.8 kg/m2, and themean number of years of schoolingwas 11.2 ± 3.8. Only 61%of the subjects had received any previous information about GWG during their antenatal care and were aware as to howmany pounds they should gain during pregnancy. Among the 61 women, 85% understood that they did not need to “eat for 2” and 99% knew that PE had benefits for their body and was safe for their baby. Half of the women practiced PE prior to pregnancy; however, only 31% continued the practice of PE during the pregnancy. Conclusion Despite understanding the need for HH during pregnancy, women still need encouragement to practice PE during pregnancy, as well as more information about GWG.

Resumo Objetivo Avaliar a relação entre mudanças no percentual do índice de massa corporal (IMC), refletidas na curva de Atalah, e resultados perinatais. Métodos Foi realizado um estudo transversal com 1.279 mulheres. Os dados sobre o peso na gestação, características sociodemográficas e resultados perinatais foram coletados através de prontuários, cartão pré-natal e entrevistas no pós-parto. As mulheres foramclassificadas de acordo coma curva de Atalah nas seguintes categorias: baixo peso, peso adequado, sobrepeso e obesidade. O IMC foi calculado na primeira e na última visita ao pré-natal e esses valores foram comparados. Resultados Houve aumento na categoria do IMC segundo a classificação de Atalah em 19,9% das mulheres grávidas e um aumento de 3,4; 5,8 e 6,4 pontos do IMC foram encontrados para mulheres respectivamente classificadas nas categorias peso adequado, sobrepeso e obesidade na primeira consulta pré-natal. As mulheres com educação secundária apresentaram menor chance de aumentar sua classificação de IMC (odds ratio [OR] 0:47 [0,24- 0,95]). As mulheres que evoluíram com o aumento na classificação de Atalah foramassociadas a cesariana (OR 1,97-2,28),macrossomia fetal (OR 4,13-12,54) e recém-nascido grande para a idade gestacional (OR 2,88-9,83). Conclusão Gestantes com ganho de peso excessivo, o suficiente para aumentar sua classificação do IMC segundo a curva de Atalah, tiverammaiores chances de cesariana e macrossomia. As mulheres classificadas como obesas na primeira visita pré-natal, de acordo com a curva de Atalah, tiveram uma grande chance de cesariana e recémnascido grande para a idade gestacional.

Abstract Objective To evaluate the relation between changes the body mass index (BMI) percentile, reflected in the Atalah curve, and perinatal outcomes. Methods A cross-sectional study with 1,279 women was performed. Data regarding gestational weight, sociodemographic characteristics and perinatal outcomes were collected through medical charts, prenatal card and interviews in the postpartum period. Women could be classified according to the Atalah curve in the following categories: low weight, adequateweight, overweight, and obese. The BMIwas calculated at the first and at the last prenatal care visits, and these values were compared. Results An increase in the BMI category according to the Atalah classification occurred in 19.9% of pregnant women, and an increase of 3.4, 5.8 and 6.4 points of BMI were found for women respectively classified in the adequate weight, overweight and obese categories at the first prenatal visit. Women with high school education presented a lower chance of increasing their BMI (odds ratio [OR] 0:47 [0.24- 0.95]). Women who evolved with an increase in the the Atalah classification were associated with cesarean section (OR 1.97-2.28), fetalmacrosomia (OR 4.13-12.54) and large for gestational age newborn (OR 2.88-9.83). Conclusion Pregnant women who gained enough weight to move up in their BMI classification according to the Atalah curve had a higher chance of cesarean section and macrosomia. Women classified as obese, according to the Atalah curve, at the first prenatal visit had a high chance of cesarean section and delivering a large for gestational age newborn.

OBJECTIVE: To generate a new body mass index curve of reference values and ranges for body mass index and weight gain during pregnancy and to compare the new curve and weight gain ranges with the currently used references. METHODS: A prospective observational study was conducted with a total of 5,656 weight and body mass index measurements in 641 women with single pregnancy who attended their first prenatal visit before 12 weeks. All the women were over 18 years old and had no medical conditions that would influence body mass index. Data were collected using prenatal charts and medical records during hospitalization for childbirth. A linear regression method was used for standard curve smoothing in the general population and for specific curves according to the baseline body mass index classification. Curves were obtained for the 5th, 10th, 50th, 85th, 90th and 95th percentiles. Concordance between the classification of women using the newly generated and currently used curves was evaluated by percentages and kappa coefficients. The weight gain was compared with the reference values of the Institute of Medicine using Student’s T test. The data were analyzed using SAS software version 9.2, and the significance level was set at 5%. RESULTS: A general reference curve of percentiles of body mass index by gestational age was established. Additionally, four specific curves were generated according to the four baseline body mass index categories. The new general curve offered percentile limits for women according to their initial body mass index and according to the Centers for Disease Control and Prevention limits, showing poor agreement with the currently used curve (48.3%). Women who were overweight or obese when starting prenatal care had higher weight gain than the Institute of Medicine recommendation. CONCLUSIONS: The new proposed curve for body mass index during pregnancy showed weak agreement with the currently used curve. The new curve provided more information regarding body mass index increase using percentiles for general and specific groups of body mass index. Overweight pregnant women showed an upward body mass index trend throughout pregnancy that increased more dramatically than those of other groups of pregnant women, and they also presented a major mean difference between weight gain and the Institute of Medicine recommendation.

Abstract INTRODUCTION: Understanding the diversity of sand flies is important for the epidemiology and control of leishmaniasis. This study aimed to understand the frequency, diversity, and seasonality of medically important sand flies in the municipality of Sinop, State of Mato Grosso, Brazil. METHODS: The study was conducted in an urban area, including four ecotypes with different levels of urbanization. The sand flies were collected using light traps for three nights per month, from May 2014 to April 2015. RESULTS: A total of 62,745 sand flies was collected, 52.34% of which were female. The frequency and diversity of sand flies was the highest in areas of permanent preservation (APPs) (96.85%), and was lower in more urbanized areas. Lutzomyia dasypodogeton was the most frequent species in the APPs. Lutzomyia antunesi was the most frequent in neighborhoods with forest fragments and neighborhoods around APPs, and L. aragaoi was the most frequent in completely urbanized neighborhoods. A higher frequency and diversity of sand flies was observed in the rainy season (87.92%) than in the dry season (12.08%). Eight medically important species were captured, and Lutzomyia antunesi, which is associated with American cutaneous leishmaniasis and visceral leishmaniasis, was observed in all ecotypes throughout the year. CONCLUSIONS: We observed a high frequency and diversity of sand flies in all urban areas, and some species collected were major vectors of leishmaniasis. These results support the need for further studies of the natural rates of infection of these insects and the circulation of the disease in hosts and vectors.

Resumo Introdução Apesar dos esforços, a mortalidade por câncer de mama se mantém elevada no Brasil e é mais frequente em regiões em que o acesso aos serviços de saúde é dificultado ou inexistente. Uma das recomendações do Instituto Nacional do Câncer (INCA) para reduzir a mortalidade é melhorar o acesso ao diagnóstico, realizando-o em até 60 dias após a suspeita. Objetivo Estabelecer o tempo decorrido (em dias) entre a suspeita e o diagnóstico do câncer de mama, subdividindo os intervalos entre os eventos: consulta médica na atenção básica; mamografia ou ultrassonografia; consulta médica especializada; biópsia; consulta médica para conclusão do diagnóstico. Métodos Estudo descritivo e seccional, realizado com 45 mulheres atendidas em um serviço público de saúde, com diagnóstico de câncer de mama efetivado em 2013. Resultados A média da demora foi de 142,6 ± 10,1 dias (12-451), com 60% dos diagnósticos efetivados entre 120 e 180 dias, e chance de efetivação do diagnóstico em até 60 dias para 8,9% da amostra. Conclusão Há necessidade de implementação efetiva das linhas de cuidado na rede de atenção oncológica, com pactuação dos fluxos entre os serviços para agilizar o acesso à assistência integral às mulheres.

Abstract Introduction Despite efforts, mortality from breast cancer remains high in Brazil and is most common in regions where access to health services is difficult or inexistent. One of the INCA’s (Instituto Nacional do Câncer) recommendations to reduce mortality is to improve the early diagnosis for up to 60 days after the suspicious. Objective To establish the elapsed time (in days) between the suspect and the breast cancer diagnosis, subgrouping the timeframe in the events of: primary care medical appointment; mammography and/or ultrasonography; specialized medical appointment; biopsy and; medical appointment for the diagnosis conclusion. Methods The descriptive and sectional study was accomplished with samples from 45 women attending the public health service, diagnosed with breast cancer in 2013. Results The average elapsed time was of 142.6 days ± 10.1 (12-451), with 60% of diagnosis performed within 120 and 180 days and effective diagnosed chance of up to 60 days for 8.9% of the cases. Conclusions A effective implementation of care lines in the cancer care network is in need, with connection between services to speed women access to comprehensive assistance.

OBJETIVO:Explorar a relação entre características morfológicas e localização histológica da metástase dentro dos linfonodos sentinelas (LS) e disseminação axilar em mulheres com câncer de mama. MÉTODOS: Foram selecionados 119 pacientes com LS positivo, submetidas à dissecação completa dos linfonodos axilares entre Julho de 2002 a Março de 2007. Foram recuperados a idade das pacientes e o tamanho do tumor primário. No tumor primário, avaliamos os graus histológico e nuclear e a invasão vascular peritumoral (IVP). Nos LS, avaliamos o tamanho da metástase, sua localização no linfonodo, o número de focos metastáticos, número de linfonodos envolvidos e a extensão extranodal. RESULTADOS: Cinquenta e um (42,8%) pacientes tiveram metástases adicionais confirmadas nos linfonodos não sentinelas (LNS). Alto grau histológico, IVP, metástase intraparenquimatosa, extensão extranodal e tamanho da metástase foram associados com LNS positivos. Metástase afetando a cápsula do LS foi associada com baixo risco de incidência de metástase adicional. Após análise multivariada, IVP e tamanho da metástase no LS foram os fatores de risco mais importantes para metástases adicionais nos LNS. CONCLUSÕES:O risco de envolvimento adicional dos LNS é maior em pacientes com IVP e tal risco aumenta progressivamente de acordo com a localização histológica da metástase no LS, que inicia na cápsula, onde aporta o linfático aferente, e termina no lado oposto, promovendo a extensão extranodal. Tamanho de metástase maior ou igual a 6,0 mm revela maior risco de metástase nos LNS.

PURPOSE: To explore the relationship between morphological characteristics and histologic localization of metastasis within sentinel lymph nodes (SLN) and axillary spread in women with breast cancer. METHODS: We selected 119 patients with positive SLN submitted to complete axillary lymph node dissection from July 2002 to March 2007. We retrieved the age of patients and the primary tumor size. In the primary tumor, we evaluated histologic and nuclear grade, and peritumoral vascular invasion (PVI). In SLNs we evaluated the size of metastasis, their localization in the lymph node, number of foci, number of involved lymph nodes, and extranodal extension. RESULTS: Fifty-one (42.8%) patients had confirmed additional metastasis in non-sentinel lymph nodes (NLSN). High histologic grade, PVI, intraparenchymatous metastasis, extranodal neoplastic extension and size of metastasis were associated with positive NLSN. SLN metastasis affecting the capsule were associated to low risk incidence of additional metastasis. After multivariate analysis, PVI and metastasis size in the SLN remained as the most important risk factors for additional metastasis. CONCLUSIONS:The risk of additional involvement of NSLN is higher in patients with PVI and it increases progressively according the histologic localization in the lymph node, from capsule, where the afferent lymphatic channel arrives, to the opposite side of capsule promoting the extranodal extension. Size of metastasis greater than 6.0 mm presents higher risk of additional lymph node metastasis.

Introduction Acquired metallo-β-lactamases (MβL) are emerging determinants of resistance in Pseudomonas aeruginosa and Acinetobacter baumannii. The objectives of this study were to phenotypically detect MβL in imipenem-resistant P. aeruginosa and A. baumannii, to investigate the association between MβL-positive strains and hospitals, and to compare the resistance profiles of MβL-producing and non-MβL-producing strains. Methods The approximation disk and combined disk assay methods were used in this study. Results A total of 18 (38.3%) P. aeruginosa isolates and 1 (5.6%) A. baumannii isolate tested positive for the presence of MβL. Conclusions These results demonstrate the need for strict surveillance and for the adoption of preventive measures to reduce the spread of infection and potential outbreaks of disease caused by MβL-producing microorganisms.

OBJETIVO: Avaliar a acurácia da espessura endometrial ecográfica e características histeroscópicas em predizer malignidade em mulheres na pós-menopausa submetidas à ressecção cirúrgica de pólipos endometriais. MÉTODOS: Quinhentos e vinte e uma (521) mulheres na pós-menopausa submetidas à ressecção histeroscópica de pólipo endometrial entre janeiro de 1998 e dezembro de 2008 foram incluídas no estudo. Para cada valor de espessura endometrial ecográfica e tamanho dos pólipos na histeroscopia, a sensibilidade, a especificidade, valor preditivo positivo (VPP) e valor preditivo negativo (VPN) foram calculados em relação ao diagnóstico histológico de malignidade. Os melhores valores de sensibilidade e especificidade para o diagnóstico de malignidade foram determinados pela curva Receiver Operating Characteristic (ROC). RESULTADOS: O diagnóstico histológico identificou a presença de pré-malignidade ou malignidade em 4,1% dos casos. A espessura endometrial medida por ultrassonografia em casos de pólipos malignos foi maior quando comparado com pólipos benignos e pré-malignos. Na histeroscopia os pólipos malignos também foram maiores. A espessura endometrial de 13 mm mostrou uma sensibilidade de 69,6%, especificidade de 68,5%, VPP de 9,3% e VPN de 98% para predizer malignidade em pólipo endometrial. A medida do pólipo por histeroscopia mostrou que para pólipos de 30 mm de tamanho, a sensibilidade foi de 47,8%, a especificidade foi de 66,1%, VPP foi de 6,1% e VPN foi de 96,5% para predizer o câncer. CONCLUSÕES: A espessura endometrial ultrassonográfica mostrou uma maior acurácia que a avaliação histeroscópica do tamanho do pólipo para predizer malignidade nessas lesões endometriais. Apesar disso, ambas as técnicas não mostraram boa acurácia para excluir a necessidade de fazer a avaliação histológica dos casos suspeitos.

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.

OBJETIVO: Avaliar a correlação entre o International Consultation on Incontinence Questionnaire - Urinary Incontinence/Short Form (ICIQ-UI/SF) e a Avaliação Urodinâmica (AU) em mulheres com incontinência urinária (IU). MÉTODOS: Foram analisados retrospectivamente dados clínicos, AU e escore do ICIQ-UI/SF de 358 mulheres com IU atendidas em clínica privada. O teste de correlação entre ICIQ-UI/SF e os parâmetros urodinâmicos foi o teste de Spearman. Foi utilizada a curva ROC, com os valores de sensibilidade e especificidade dos escores do ICIQ-UI/SF apresentados pelas pacientes, para identificar o valor do questionário que determinasse a presença da alteração urodinâmica estudada. Para o cálculo do valor p foi utilizado o teste do c² ou exato de Fisher. O nível de significância foi de 5% e o software utilizado para análise foi o SAS versão 9.2. RESULTADOS: As pacientes com IU aos Esforços segundo a AU - IUE urodinâmica - representaram 67,3% do total; aquelas com IUE na AU e Hiperatividade Detrusora (HD) - IUM urodinâmica - 16,2%, e as pacientes com HD isolada - HD - 7,3% do total. As pacientes com AU normal representaram 9,2% do total da amostra. Houve associação significativa entre escore ³14 no ICIQ-UI/SF e as pacientes com IUE urodinâmica e IUM urodinâmica. Pacientes com Pressão de Perda ao Esforço (PPE) £90 cmH2O apresentaram escore ao ICIQ-UI/SF³15. O teste de Spearman mostrou correlação inversa fraca entre o escore e a PPE, porém não mostrou correlação entre esse escore e a Capacidade Cistométrica Máxima (CCM) ou com o volume vesical no primeiro desejo miccional. CONCLUSÃO: Houve associação entre o escore do ICIQ-UI/SF e IUE urodinâmica (isolada ou associada à HD); porém não houve associação com a HD isolada. Quanto menor o valor da PPE, maior o escore total do ICIQ-UI/SF. O ICIQ-UI/SF não foi capaz de discriminar o tipo de IU na população estudada.

PURPOSE: To evaluate the correlation between the International Consultation on Incontinence Questionnaire - Urinary Incontinence/Short Form (ICIQ-UI/SF) and Urodynamic evaluation (UE) in women with urinary incontinence (UI). METHODS: Clinical data, UE and ICIQ-UI/SF scores for 358 patients from private health service were analyzed retrospectively . The correlation between ICIQ-UI/SF and urodynamic parameters was determined by Spearman's test. A ROC curve with the sensitivity and specificity of the ICIQ-UI/SF scores was utilized to establish the value of the questionnaire that would predict an altered urodynamic parameter. The c² test or Fisher's exact test was used to calculate the p-value. The level of significance was 5% and the software used was SAS 9.2. RESULTS: Sixty-seven point three percent of the patients presented Stress UI (SUI) according to the UE (urodynamic SUI); those with SUI and Detrusor overactivity (DO) at UE represented 16.2% of the women (SUI+DO), and those with only DO at UE (DO) represented 7.3% of the women. Patients with normal UE represented 9.2% of the women. There was a significant association between ICIQ-UI/SF scores ³14 and patients with urodynamic SUI, with or without DO. Patients with Valsava Leak Point Pressure (VLPP)£90 cmH2O presented ICIQ-UI/SF³15. Spearman's test showed a weak inverse correlation between ICIQ-UI/SF score and VLPP, although it did not show any correlation with maximum cystometric capacity or with bladder volume on first desire to void. CONCLUSION: There was an association between ICIQ-UI/SF score and patients with SUI, with or without DO, but no association between the score and patients with DO alone. The lower the VLPP value, the higher the ICIQ-UI/SF score. The ICIQ-UI/SF was not able to distinguish the different types of UI in the studied population

Culex quinquefasciatus é vetor de patógenos humanos, incluindo nematódeos filarídeos e vários vírus. Embora a sua relevância epidemiológica varie entre as diferentes regiões geográficas, o conhecimento da estrutura genética da população é ainda incipiente. Em vista disso, foram avaliados os níveis de diversidade genética de Cx. quinquefasciatus e de híbridos Cx. quinquefasciatus x Cx. pipiens de nove cidades do Brasil e em La Plata, na Argentina. Para os testes foram utilizados fragmentos dos genes mitocondriais cox1 e nd4, juntamente com coxA e wsp do endossimbionte Wolbachia, herdado maternalmente. O fragmento nd4 não apresentou variação entre as amostras, e o cox1 exibiu quatro haplótipos que separaram dois tipos de Cx. quinquefasciatus, com um deles agrupado no sul do Brasil. Os dados de sequência mostraram baixa diversidade, sendo esta discutida. Ambas as amostras de mosquitos brasileiros e argentinos estão infectados com uma única cepa de Wolbachia. A diversidade apresentada por nd4 e cox1 não é congruente com a estrutura da população revelada por marcadores nucleares e morfologia alar de estudos anteriores com estas mesmas populações. Pesquisas com Cx. quinquefasciatus devem, se possível, avaliar a diversidade por DNA mitocondrial na luz de outros marcadores.

Culex quinquefasciatus is a vector of human pathogens, including filarial nematodes and several viruses. Although its epidemiological relevance is known to vary across geographical regions, an understanding of its population genetic structure is still incipient. In light of this, we evaluated the genetic diversity of Cx. quinquefasciatus and Cx. pipiens x Cx. quinquefasciatus hybrids collected from nine localities in Brazil and one site in Argentina. We used mitochondrial genes cox1 and nd4, along with the coxA and wsp genes of the maternally-inherited Wolbachia endosymbiont. The nd4 fragment was invariant between samples, whilst cox1 exhibited four haplotypes that separated two types of Cx. quinquefasciatus, one clustered in southern Brazil. Low sequence diversity was generally observed, being discussed. Both Brazilian and Argentinian mosquitoes were infected with a single Wolbachia strain. As reported in previous studies with these populations, cox1 and nd4 diversity is not congruent with the population structure revealed by nuclear markers or alar morphology. Future Cx. quinquefasciatus research should, if possible, evaluate mtDNA diversity in light of other markers.

Este estudo contribui para o conhecimento de espécies de Anopheles, incluindo vetores de Plasmodium do oeste da Amazônia brasileira, em Porto Velho, no estado de Rondônia. Esta região vem passando por mudanças ambientais, como consequência de agricultura extensiva e projetos hidroelétricos que causam desmatamento, favorecendo o desenvolvimento de algumas espécies de mosquitos. Assim, a proposta deste estudo é registrar a presença de espécies de anofelinos na área, sendo conduzidas coletas de mosquitos em três locais, ao longo de uma linha de transmissão de energia elétrica. Cada uma das localidades foi amostrada três vezes, no período de 2010 a 2011. Os principais mosquitos adultos capturados em armadilhas de Shannon foram Anopheles darlingi, An. triannulatus, An. nuneztovari l.s., An.gilesi e An. costai. Assim como as formas larvárias Anopheles braziliensis, An. triannulatus, An. darlingi, An. deaneorum, An. marajoara, An. peryassui, An. nuneztovari l.s. e An. oswaldoi-konderi, coletadas em criadouros. Anopheles darlingi foi a espécie mais coletada na região. Em adição, discutiu-se sistemática de Culicidae, distribuição de fauna e aspectos da malária em ambientes modificados do oeste da Amazônia brasileira.

This study contributes to knowledge of Anopheles species, including vectors of Plasmodium from the western Brazilian Amazon in Porto Velho, Rondônia State. The sampling area has undergone substantial environmental changes as a consequence of agricultural and hydroelectric projects, which have caused intensive deforestation and favored habitats for some mosquito species. The purpose of this study was to diagnose the occurrence of anopheline species from collections in three locations along an electric-power transmission line. Each locality was sampled three times from 2010 to 2011. The principal adult mosquitoes captured in Shannon trap were Anopheles darlingi, An. triannulatus, An. nuneztovari l.s., An.gilesi and An. costai. In addition, larvae were collected in ground breeding sites for Anopheles braziliensis, An. triannulatus, An. darlingi, An. deaneorum, An. marajoara, An. peryassui, An. nuneztovari l.s. and An. oswaldoi-konderi. Anopheles darlingi was the most common mosquito in the region. We discuss Culicidae systematics, fauna distribution, and aspects of malaria in altered habitats of the western Amazon.
