(Educação Ambiental em Ação, 2018-06-14) Furukava, Marciano; Braz, Regina de Fátima dos Santos; Colombo, Ciliana Regina; Medeiros, Marjorie da Fonseca e Silva; Azevedo, Paulo Roberto Medeiros de; Souza, Maria de Fátima de
O modelo econômico capitalista baseado no consumo e crescimento econômico tem conduzido à geração de grande volume de resíduos sólidos, oque deu origem à atividade de catador de recicláveis. O objetivo deste trabalho foi avaliar alguns riscos socioambientais e a repercussão destes na saúde dos catadores de recicláveis das cooperativas de Natal-RN. Foi aplicado um instrumento com questões sobre aspectos socioeconômicos, ambientais e da saúde dos catadores. Os resultados mostraram que dentre as variáveis referentes às condições das moradias, a destinação das águas cinzas foi significativamente associada à frequência de diarreia (p=0,04). A disponibilização de EPIs foi insuficiente e deve estar associada com a frequência de 38,6% de acidentes do tipo corte. As doenças mais frequentemente relatadas foram dor de cabeça, problemas de coluna, de visão, diarreia e varizes, com as respectivas frequências de 71,0%; 67,1%; 37,7%;34,3% e 24,3%. Os problemas de visão, coluna e varizes foram significativamente mais frequentes nas mulheres do que entre os homens(p=0,02, p=0,03 e p=0,001, respectivamente). As condições insalubres da atividade de catador predispõem ao surgimento e/ou agravamento de problemas de saúde desses trabalhadores

(Elsevier, 2009) Campos, Ana Karina Couto; Cardonha, Ângela Maria Soares; Pinheiro, Liana Bacurau Galvão; Ferreira, Neide Rocha; Azevedo, Paulo Roberto Medeiros de; Stamford, Tânia Lúcia Montenegro
The aim of this study was to assess the hygiene practices of food handlers in municipal schools of Natal, Brazil, where 27 public schools were evaluated, using a checklist and microbiological analysis of hands. It was found that 74.1% of the handlers did not receive periodic training, 51.9% did not undergo annual health examinations and 100% did not practice proper hand hygiene, a situation that reflected significantly (p < 0.05) in hand contamination, in which fecal coliforms were detected on 55.6% of the hands analyzed. It was concluded that the schools studied did not have appropriate hygienic conditions, suggesting the need for interventions that ensure the quality of school food served to the children

(Universidade Federal do Rio Grande do Norte, 2010-05-07) Azevedo, Paulo Roberto Medeiros de; Costa, Antônio de Lisboa Lopes; ; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4786083Z7&dataRevisao=null; ; http://lattes.cnpq.br/3295064535726146; Galvão, Hébel Cavalcanti; ; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4794937Z9; Ferreira, Maria ângela Fernandes; ; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4767285D3; Oliveira, Márcio Campos; ; http://lattes.cnpq.br/5703051980918880; Maciel, Shirley Suely Soares Veras; ; http://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4773895T8
Introdução: O câncer de boca é classificado como uma das dez maiores incidências de câncer no mundo. No Brasil, as taxas de incidência e de mortalidade por esse câncer encontram-se entre as mais elevadas do mundo. Para o câncer intraoral (língua, gengiva, base da boca e outras e não especificadas partes da boca), a taxa acumulada de sobrevida após 5 anos é menor que 50%. Objetivo: Estimar a probabilidade acumulada de sobrevida após 5 anos, ajustar o modelo de regressão de Cox para os cânceres de boca e de orofaringe, segundo faixa etária, sexo, morfologia e localização, para a cidade de Natal, Brasil. Descrever os coeficientes de mortalidade e de incidência dos cânceres de boca e de orofaringe e as tendências desses coeficientes para a cidade de Natal, nos períodos de 1980 a 2001 e de 1997 a 2001, respectivamente. Metodologia: Foi obtida a sobrevida de pacientes registrados entre 1997 e 2001 no Registro de Câncer de Base populacional de Natal. Foram testadas as diferenças entre as curvas de sobrevida através do teste log-rank. O modelo de riscos proporcionais de Cox foi utilizado para estimativas das razões de riscos. O modelo de regressão linear simples foi utilizado para as análises de tendência dos coeficientes de incidência e de mortalidade. Resultados: A probabilidade acumulada após 5 anos para todos os casos foi de 22,9%. Os pacientes com neoplasia maligna indiferenciada têm 4,7 vezes mais risco de morrer do que aqueles com carcinoma epidermóide, enquanto que os pacientes com câncer de orofaringe têm 2,0 vezes mais risco de morrer do que aqueles com câncer de boca. Os coeficientes padronizados de mortalidade e de incidência do câncer de boca em Natal foram, respectivamente, 2,9 e 4,3 por 100 mil habitantes. Para o câncer de orofaringe 10 os coeficientes obtidos de mortalidade e de incidência foram, respectivamente, 1,1 e 0,7 por 100 mil habitantes. Conclusão: Identifica-se uma baixa taxa de sobrevida após 5 anos. Pacientes com câncer de boca apresentam menos risco de morte, independentemente dos fatores considerados neste estudo. Também de forma independente dos demais fatores, a neoplasia maligna indiferenciada apresenta um maior risco de morte. As magnitudes dos coeficientes de incidência encontradas não são consideradas elevadas, enquanto que de forma contrária estão as magnitudes dos coeficientes de mortalidade
Comparative immunohistochemical expression of RANK, RANKL and OPG in radicular and dentigerous cysts
(Elsevier, 2011-05) Moraes, Maiara de; Lucena, Hévio Freitas de; Azevedo, Paulo Roberto Medeiros de; Queiroz, Lélia Maria Guedes; Costa, Antonio de Lisboa Lopes
Objective: Receptor activator of nuclear factor-kB (RANK), RANK ligand (RANKL) and osteoprotegerin (OPG) are members of the superfamily of ligands and receptors of tumour necrosis factor family involved in bone metabolism. The formation, differentiation and activity of osteoclasts are regulated by these proteins. To clarify the roles of osteoclast regulatory factors in cystic expansion of odontogenic cysts, expression of these proteins were analysed in radicular and dentigerous cysts. Design: The immunohistochemistry expression of these biomarkers were evaluated and measured in lining epithelium and fibrous capsule of the radicular (n = 20) and dentigerous cysts (n = 20). Results: A similar expression in lining epithelium was observed in the lesions. The fibrous capsule of dentigerous cyst showed a higher content of RANK-positive and RANKL-positive cells than fibrous capsule of radicular cyst. In the lining epithelium the RANKL/OPG ratio showed higher numbers of OPG-positive than RANKL-positive cells, whereas fibrous capsule of the cysts had a tendency to present a similar expression (OPG = RANKL). Conclusion: Ours findings indicate the presence of RANK, RANKL and OPG in cysts. Moreover, increased expression of OPG compared to RANKL in the lining epithelium could contribute to the differential bone resorption activity in theses lesions.

(Scielo, 2009-02) Fernandes, José Veríssimo; Rodrigues, Silvia Helena Lacerda; Costa, Yuri Guilherme Alexandre Silva da; Silva, Luiz Cláudio Moura da; Brito, Alípio Maciel Lima de; Azevedo, Judson Welber Veríssimo de; Nascimento, Ermeton Duarte do; Azevedo, Paulo Roberto Medeiros de; Fernandes, Thales Allyrio Araújo de Medeiros
OBJETIVO: Analisar conhecimentos, atitudes e práticas das mulheres em relação ao exame citológico de Papanicolaou e a associação entre esses comportamentos e características sociodemográfi cas MÉTODOS: Inquérito domiciliar com abordagem quantitativa. Foram entrevistadas 267 mulheres com idade de 15 a 69 anos, selecionadas de forma estratifi cada aleatória, residentes no município de São José do Mipibu, RN, em 2007. Utilizou-se questionário com perguntas pré-codifi cadas e abertas, cujas respostas foram descritas e analisadas quanto à adequação dos conhecimentos, atitudes e prática das mulheres em relação ao exame preventivo de Papanicolaou. Foram realizados testes de associação entre as características sociodemográfi cas e os comportamentos estudados, com nível de signifi cância de 5%. RESULTADOS: Apesar de 46,1% das mulheres entrevistadas terem mostrado conhecimento adequado, proporções de adequação signifi cativamente maiores foram observadas em relação às atitudes e prática quanto ao exame: 63,3% e 64,4%, respectivamente. O maior grau de escolaridade apresentou associação com adequação dos conhecimentos, atitudes e prática, enquanto as principais barreiras para a realização do exame relatadas foram descuido, falta de solicitação do exame pelo médico e vergonha. CONCLUSÕES: O médico é a principal fonte de informação sobre o exame de Papanicolau. Entretanto, mulheres que vão a consultas com maior freqüência, embora apresentem prática mais adequada do exame, possuem baixa adequação de conhecimento e atitude frente ao procedimento, sugerindo que não estejam recebendo as informações adequadas sobre o objetivo do exame, suas vantagens e benefícios para sua saúde.
Ecological interactions among phlebotomines (Diptera: Psychodidae) in an agroforestry environment of northeast Brazil
(Wiley, 2013-12) Pinheiro, Marcos Paulo Gomes; Silva, José Hilário Tavares; Cavalcanti, Katrine Bezerra; Azevedo, Paulo Roberto Medeiros de; Ximenes, Maria de Fátima Freire de Melo
Phlebotomine vectors transmit parasites and can cause visceral leishmaniasis (VL) or cutaneous leishmaniasis (TL). Phlebotomine females are hematophagous but need to ingest carbohydrates, possibly promoting the development of protozoan parasites in their digestive tract. The present study evaluated the species composition and abundance across several habitats in a metropolitan landscape, as well as associations among phlebotomines, plants, and local climatic parameters. Three consecutive monthly collections were carried out in an Atlantic Forest fragment, using CDC light traps in peridomestic areas and cashew, coconut, and mango tree.plantations. Eight species of phlebotomine were captured: Evandromyia evandroi, Lutzomyia longipalpis, Psathyromyia shannoni, Sciopemyia sordellii, Evandromyia walkeri, Psychodopygus wellcomei, Nyssomyia whitmani, and Nyssomyia intermedia, primarily from the forest environment. L. longipalpis was confirmed as a species adapted to anthropic environments, while P. wellcomei was shown to be predominately forest-dwelling. Phlebotomines exhibited diversified food consumption patterns in relation to carbohydrate sources. They fed on both native and exotic species of arboreal and shrubby vegetables and gramineous plants.
Food safety in brazilian popular public restaurants: food handlers knowledge and practices
(Journal of Food Safety, 2018) Seabra, Larissa Mont'Alverne Jucá; Azevedo, Paulo Roberto Medeiros de; Souza, Camila Valdejane Silva de; https://orcid.org/0000-0002-1878-4283
This study aims to assess food safety knowledge and practices of food handlers in popular public restaurants in Brazil. A questionnaire has been applied with 70 food handlers in different municipalities, with questions related to food safety knowledge and food safety self-reported practices, and observed practices. To check hygienic-sanitary conditions of restaurants, a check- list has been applied. Regarding food safety knowledge, an average of 72.64% of correct answers has been observed. Food safety self-reported practices presented 80.71% of adequacy, while observed practices were 75.40%. A positive correlation has been observed between food safety knowledge and self-reported practices of handlers. The observed food safety practice of handlers presented no correlation with food safety knowledge and self-reported practices. The average adequacy of hygienic-sanitary conditions was 68.08%, classifying the units as “regular.” Despite satisfactory results related to the handlers' food safety knowledge and practices, the hygienic-sanitary conditions of the restaurants are of concern.
Frequência e perfil de resistência de Klebsiella spp. em um hospital universitário de Natal/RN durante 10 anos
(Jornal Brasileiro de Patologia e Medicina Laboratorial, 2011-12) Oliveira, Claudio Bruno Silva de; Dantas, Valéria Cristina Ribeiro; Neto, Renato Motta; Azevedo, Paulo Roberto Medeiros de; Melo, Maria Celeste Nunes de
Introdução: As espécies de Klebsiella spp. podem causar vários tipos de infecções, principalmente hospitalares, e têm merecido destaque pelos seus variados e emergentes mecanismos de resistência. Objetivos: Determinar a frequência de isolamento e a caracterização do perfil de resistência de Klebsiella spp. em um hospital universitário durante um período de 10 anos e, ainda, avaliar a tendência para o crescimento dessa resistência. Material e método: Fez-se um estudo descritivo e retrospectivo a partir de dados coletados nos livros de registro do Laboratório de Microbiologia Clínica do hospital investigado, correspondentes ao período de janeiro de 1999 a dezembro de 2008. Resultado: A frequência de isolamento de Klebsiella spp. foi de 13,4% com predominância em uroculturas (56,4%). Houve aumento significativo na resistência para a maioria dos antimicrobianos testados ao longo do período analisado com tendência para o crescimento da mesma. Nesse período, isolou-se 23% de Klebsiella spp. com fenótipo produtor de betalactamases de amplo espectro (ESBL). Discussão: O isolamento de Klebsiella spp. resistente a antimicrobianos em amostras de origem clínica e a detecção da tendência do crescimento da resistência, inclusive às drogas de reserva terapêutica, são motivos de grande preocupação. Nesse hospital, a implantação de métodos de triagem e de confirmatórios para os mecanismos de resistência de Klebsiella spp. poderiam auxiliar no diagnóstico e no tratamento das infecções causadas por esse microrganismo. Conclusão: A tendência de crescimento na resistência aos antibióticos detectada neste estudo reforça a importância de monitoramentos contínuos. Estes elucidam características locais, orientando para melhores medidas de controle.

(ISRN Obstetrics and Gynecology, 2014-03) Miranda, Cleine Aglacy Nunes; Lima, Érika Galvão; Lima, Diego Breno Soares de; Cobucci, Ricardo Ney Oliveira; Cornetta, Maria da Conceição de Mesquita; Fernandes, Thales Allyrio Araújo de Medeiros; Azevedo, Paulo Roberto Medeiros de; Azevedo, Jenner Chrystian Veríssimo de; Araújo, Josélio Maria Galvão de; Fernandes, José Veríssimo
Objective. To evaluate the prevalence of HSV-1 and HSV-2 in pregnant and nonpregnant women, testing the correlation between DNA of the viruses with colposcopic and/or cytological changes, and evaluate association with sociodemographic characteristics and sexual activity. Methods. Included in this study were 106 pregnant and 130 nonpregnant women treated at primary health care units ofNatal, Brazil, in the period 2010-2011.Thepatientswere examined by colposcopy, and two cervical specimenswere collected: one for cytology examination and another for analysis by PCR for detection ofHSV-1 and HSV-2. Results.HSV-1 alone was detected in 16.0% of pregnant and 30.0% of nonpregnant women. For HSV-2, these rates were 12.3% and 15.5%, respectively. HSV-2 had a higher correlation with cytology and/or colposcopy changes than HSV-1 did. Genital HSV-1 infection was not associated with any of the variables tested, whereas HSV-2 infection was associated with ethnicity, marital status, and number of sexual partners. Conclusions. The prevalence of HSV-1 was higher than that observed for HSV-2 in both pregnant and nonpregnant women. The genital infection by HSV-2 was higher in women with changed colposcopy and/or cytology, and it was associated with ethnicity, marital status, and number of sexual partners.
Genital tract infection with Chlamydia trachomatis in women attended at a cervical cancer screening program in Northeastern from Brazil
(Springer, 2014-10) Magalhães, Paulo André Freire; Miranda, Cleine Aglacy Nunes; Lima, Érika Galvão; Moizéis, Raíza Nara Cunha; Lima, Diego Breno Soares de; Cobucci, Ricardo Ney Oliveira; Fernandes, Thales Allyrio Araújo de Medeiros; Azevedo, Jenner Chrystian Veríssimo de; Azevedo, Paulo Roberto Medeiros de; Araújo, Josélio Maria Galvão de; Fernandes, José Veríssimo
Purpose This cross-sectional study aimed to estimate the prevalence of Chlamydia trachomatis (CT) infection alone and in combination with human papillomavirus (HPV). Furthermore, the study investigates whether the CT infection increases the risk of contracting HPV and whether the presence of both pathogens is associated with a higher prevalence of cervical lesions. Methods Cervical samples of 1,134 asymptomatic women enrolled in a screening program for cervical cancer were analyzed. Two cervical specimens were collected from each patient, one for cytologic examination and the other for detection of CT by polymerase chain reaction (PCR), using a primer pair which amplifies a specific sequence of the DNA plasmid. Results The overall prevalence rate infection was 10.9 %, being 10 % in the women with normal cytology, 13.8 % in those with atypical squamous cells of undetermined significance (ASC-US), and 25 % with low-grade squamous intraepithelial lesion (LSIL). The infection by CT did not increase the risk of acquiring HPV infection. The higher prevalence of LSIL in women co-infected with HPV and CT is possibly due to HPV. Conclusion CT infection was more prevalent in younger women aged up to 32 years, who had an early onset of reproductive activity and a history of having had multiple sexual partners lifelong may be at a greater risk of acquiring infection of the genital tract by C. trachomatis.
Human papillomavirus infection in women attendes at a cervical cancer screening service in Natal, Brazil
(Brazilian Journal of Microbiology, 2008-07) Fernandes, Thales Allyrio Araújo de Medeiros; Meissner, Rosely de Vasconcellos; Bezerra, Laelson Freire; Azevedo, Paulo Roberto Medeiros de; Fernandes, José Veríssimo
We analyzed cervical specimens of 202 women, aged 15 to 64 years, attended at Luis Antonio Hospital, Natal, Brazil, to determine the prevalence of HPV and identify the more frequent genotypes and risk factors for HPV nfection in women attended at a cervical cancer screening service. Two specimens were collected from each patient: one for cytological examination and the other to detect HPV DNA by PCR, and typing by dot blot hybridization. A total of 54.5% of the sample had normal cytology and 45.5% had cytological alterations. HPV was detected in 24.5% of the cytologically normal women and in 59.8% of those with altered cytology. Both single and double HPV infection increased the likelihood of cytological alterations. Thirteen types of HPV were identified, most of which were high risk. HPV 16 was the most prevalent single-type infection, followed by HPV 58. The most frequent double infection was the association between HPV 56 and 57. The prevalence of HPV in cytologically normal women was greater than that reported for countries on all the continents except Africa. The inverse was observed in women with cytological alterations. The distribution of HPV types was similar to that described for the Americas, with some differences. Multiple sexual partners was the only risk factor showing an association with the presence of HPV infection.
Immunoexpression of transforming growth factor beta and interferon gamma in radicular and dentigerous cysts
(Elsevier, 2014-09) Moraes, Maiara de; Rocha-Neto, Pedro Carlos da; Matos, Felipe Rodrigues de; Lopes, Maria Luiza Diniz de Sousa; Azevedo, Paulo Roberto Medeiros de; Costa, Antonio de Lisboa Lopes
Introduction: The aim of this study was to evaluate and compare the immunohistochemical expression of transforming growing factor beta (TGF-b) and interferon gamma (IFN-g) between radicular cysts (RCs) and dentigerous cysts (DCs). Methods: Twenty RCs and DCs were selected for analysis of the immunoexpression of TGF-b and IFN-g in the epithelium and capsule. Results: The cell reactivity of TGF-b and IFN-g in the lining epithelium and capsule of RCs showed no significant differences when compared with DCs (P > .05). There was a tendency of a higher expression of TGF-b in the capsule of DCs. Conclusions: Our results showed the presence of TGF-b and IFN-g in RCs and DCs, supporting the hypothesis that both participate in the development of these lesions, where IFN-g usually plays a role in bone resorption, which is counterbalanced by the osteoprotective activity performed by TGF-b.
Insect vectors and their relationship with sustainable development indicators in neighborhoods of Natal, northeastern Brazil
(Gaia Scientia, 2016-09) Araujo, Paulo Sérgio Fagundes; Souto, Maria Cristiana da Silva; Azevedo, Paulo Roberto Medeiros de; Ximenes, Maria de Fatima Freire de Melo
This study aimed to correlate sustainable development indicators with the occurrence of mosquitoes from the genus Aedes and phlebotominae sand flies, vectors of dengue fever, American visceral leishmaniasis and American tegumentary leishmaniasis, in order to establish a relationship between infestation indices and sustainability conditions in southern and northern neighborhoods of Natal, Brazil, adjacent to environmental protection zones 5 and 9, respectively. Data were obtained on Aedes aegypti and A. albopictus breeding sites and captures of phlebotominae sand flies of the genus Lutzomyia in the study area between 2006 and 2008, from the Center of Zoonosis Control of the Municipal Health Secretariat, and correlated with environmental and social indicators. Factorial analysis was applied to transform these indicators into a sustainability index for each neighborhood studied (Neighborhood Sustainability Index – NSI). Relating these indices with the occurrence of insect vectors at these sites shows a high positive correlation between SID and the Breteau index of A. aegypti (p=0.028) and with the index of household infestation by phlebotominae sand flies (p=0.01). This reveals a pattern allowing the association of sustainability conditions in the study areas with the occurrence of these insects. Analyses demonstrate the occurrence of a larger number of A. aegypti breeding sites and higher indices of household infestation by phlebotominae sand flies in neighborhoods with lower sustainability indices. Knowledge of the relationship between sustainable development indicators and the occurrence of zoonotic vectors may contribute to public health programs as well as to a restructuring of public policies in the study areas.

Knowledge about HPV and screening of cervical cancer among women from the metropolitan region of Natal, Brazil
(Hindawi Publishing Corporation, 2013-03) Lima, Érika Galvão; Lima, Diego Breno Soares de; Miranda, Cleine Aglacy Nunes; Pereira, Valeska Santana de Sena; Azevedo, Jenner Chrystian Veríssimo de; Araújo, Josélio Maria Galvão de; Fernandes, Thales Allyrio Araújo de Medeiros; Azevedo, Paulo Roberto Medeiros de; Fernandes, José Veríssimo
Objective. The purpose of this study was to assess the knowledge level about HPV and screening of cervical cancer in women from the metropolitan region of Natal, Brazil. Materials and Methods. A descriptive cross-sectional study involving sexually active women was conducted.Theparticipants were submitted to a face-to-face interview, using a structured questionnaire that permitted the quantification of data and opinions of the respondents. Results.Most participants (70.9%) had poor knowledge about HPV and also the Pap test (53.0%). The high level of knowledge about HPV was associated with age, education, marital status, household income, and pregnancy, while the high level of knowledge about the Pap test proved to be associated only with education and household income. Conclusion.The results highlight the need for performing educational campaigns emphasizing the role of HPV in the etiology of cervical lesions of different degrees, including cervical cancer, as well as the importance of having a Pap test regularly to prevent these diseases.
Knowledge, attitudes and practices regarding the Pap test among women in northeastern Brazil
(SciELO, 2014) Albuquerque, Carla Lorenna Ferreira de; Costa, Marla da Paschoa; Nunes, Felipe Moreira; Freitas, Roberto Wagner Junior Freire de; Azevedo, Paulo Roberto Medeiros de; Fernandes, José Veríssimo; Rego, Juciane Vaz; Barreto, Humberto Medeiros
CONTEXT AND OBJECTIVE: The Papanicolaou (Pap) test has been shown to be e ective in preventing cervical cancer. However, both the national and international literature shows that Pap testing has not reached the level of coverage desired. The objective of this study was to assess women’s knowledge, attitudes and practices regarding the Pap test and to investigate whether there are any associations between these three factors and the women’s sociodemographic characteristics. DESIGN AND SETTING: Cross-sectional descriptive study conducted in Floriano, Piauí. METHODS: The study was conducted among 493 women between November 2009 and December 2010. A questionnaire with precoded questions was used, and the responses were analyzed in terms of appropriateness in relation to the Pap test. RESULTS: The degrees of adequacy of knowledge, attitudes and practices regarding the Pap test were 36.7%, 67.2% and 69.6%, respectively. Among the main barriers against testing, absence of symptoms and a sense of embarrassment were the most notable. CONCLUSIONS: Women who visit doctors periodically had the most appropriate practices regarding the Pap test, but their knowledge of the procedure was poor. This suggests that these women were not receiving adequate information about the bene ts of periodic testing.

(International Journal of Gynecology and Obstetrics, 2009) Fernandes, José Veríssimo; Meissner, Rosely de Vasconcellos; Carvalho, Maria Goretti Freire de; Fernandes, Thales Allyrio Araújo de Medeiros; Azevedo, Paulo Roberto Medeiros de; Villa, Luisa Lina
Objectives: To assess the prevalence of human papillomavirus (HPV) infection according to cervical cytologic status in northeastern Brazil; identify other risk factors for low- and high-grade squamous intraepithelial lesions (LSILs and HSILs); and identify the most prevalent HPV genotypes associated with the lesions. Method: Two cervical smears were collected from 250 women referred for cancer screening, one for cytologic examination and the other to test for the presence of HPV by PCR with genotyping by dot blot hybridization. Result: There were 110 healthy cervices, 82 LSILs, and 58 HSILs. The overall HPV prevalence was 48%, with higher rates for HSILs, and HPV-16 was the most prevalent type. Age, multiple sexual partners, type of HPV present, smoking, and early onset of sexual activity were risk factors for cervical lesions. Conclusion: Age, multiple sexual partners, and infection with HPV-16 increased the risk of having LSILs or HSILs. Early onset of sexual activity and smoking only increased the risk of having HSILs.
Prevalência de transtornos mentais comuns e avaliação da qualidade de vida no climatério
(Revista da Associação Médica Brasileira, 2007-07) Galvão, Lílian Lira Lisboa Fagundes; Farias, Maria Cláudia Saldanha; Azevedo, Paulo Roberto Medeiros de; Vilar, Maria José Pereira; Azevedo, George Dantas de
OBJETIVO. Avaliar a prevalência de transtornos mentais comuns e a qualidade de vida (QV) relacionados à saúde em mulheres no climatério. MÉTODOS. Foram incluídas 191 mulheres (entre 45 e 65 anos) em estudo analítico transversal. Um questionário, contendo informações pessoais, hábitos/saúde e dados demográficos, foi administrado em associação a instrumentos validados para medir qualidade de vida (SF-36, Medical Outcomes Study 36-item Short-Form Health Survey) e estimar a prevalência de transtornos mentais comuns (SRQ-20, Self Reporting Questionnaire). RESULTADOS. Com a utilização do SRQ-20 e empregando ponto de corte de oito ou mais respostas afirmativas, 39,8% das mulheres foram classificadas como apresentando transtornos mentais comuns. Evidenciou-se maior prevalência de transtornos mentais comuns e piores escores de QV nas mulheres com pouca escolaridade, baixa renda familiar e que não exerciam atividades profissionais fora do domicílio. Os escores médios para todos os domínios do SF-36 foram significativamente mais baixos nas mulheres categorizadas por apresentarem transtornos mentais comuns. CONCLUSÃO. A prevalência de transtornos mentais comuns é elevada na amostra de mulheres no climatério e está associada com repercussões negativas sobre sua qualidade de vida. Fatores psicossociais exercem significativa influência, e estratégias de suporte psicológico deveriam ser instituídas no contexto das políticas de saúde voltadas para mulheres no climatério.
