ABSTRACT

PROBLEM OF RESEARCH: Candida spp. biofilms are complex microbial communities that have been associated with increasing resistance to clinically available antifungal drugs. Hence, novel pharmacological approaches with ability to inhibit biofilm formation have been investigated. AIM OF STUDY: The aim was to analyze in vitro antifungal activity of Euterpe oleracea Mart. (açaí berry) extract on biofilm strains of Candida albicans, C. parapsilosis, and C. tropicalis that were formed on abiotic surfaces. REMARKABLE METHODOLOGY: Biofilms of C. albicans, C. parapsilosis, and C. tropicalis were grown in vitro. They were then treated with E. oleracea Mart. extract at different concentrations (7.8, 15.6, 31.2, 62.5, 125, 250, 500, and 1000 µg/mL) for evaluation of both biofilm removal and anti-biofilm activity. REMARKABLE RESULTS: All Candida species analyzed formed biofilms on abiotic surfaces. Yet, increased biofilm formation was displayed for C. tropicalis in comparison with the other two species. E. oleracea Mart. extract was shown to inhibit biofilm formation at all concentrations used when compared to no treatment (p < 0.05). SIGNIFICANCE OF THE STUDY: In the current study, the extract of E. oleracea Mart. demonstrated antifungal activity against Candida albicans, C. parapsilosis, and C. tropicalis biofilms, regardless of the dose utilized. These results are important to evaluate a natural product as antifungal for Candida species.

ABSTRACT

BACKGROUND: Flavonoids from a variety of fruits, including açaí, have beneficial antioxidant activity in several diseases, including cancer. Breast cancer is the second most prevalent cancer among Brazilian women. Studies have shown the action of flavonoids on neoplastic cells, as well as on diabetes and neurodegenerative and cardiovascular diseases. OBJECTIVE: To analyze the relationship between the consumption of açaí and the presence of chronic diseases in women residing in the rural area of São Luís, Maranhão. METHODS: A convenience sample of 150 women residing in the Maracanã neighborhood in São Luís, Maranhão, was used; the collected data included sociodemographic characteristics, habits, sexual and reproductive history, consumption of açaí, and history of cancer and other chronic diseases. The sample was divided into women who consumed açaí at least once a week (cases) and women who did not consume açaí (controls). Statistical analysis was performed to assess the relationships between those variables and the consumption of açaí. RESULTS: A total of 141 women (94%) consumed açaí. Among these, 79.3% were aged between 20 and 50 years, 78.67% were farmers or housewives, 64.67% were Pardo (mixed race), 76.67% were nonsmokers, 70% were not receiving hormonal therapy, 40.67% had already undergone mammography, 28% had already undergone breast ultrasound, and 27.33% had a family history of cancer, with breast cancer being the second most prevalent cancer. There was a higher prevalence of hypertension among women who did not consume açaí than that among those who did; however, previous cancer, family history of cancer, heart disease, and diabetes were more prevalent among the consumers of açaí. There were no statistically significant relationships. CONCLUSION: Flavonoids are known to have a beneficial effect on some types of neoplastic cells and other diseases; therefore, larger studies are necessary to better evaluate the beneficial effects of consuming foods containing flavonoids on these diseases.

ABSTRACT

BACKGROUND: Human papillomavirus (HPV) is a member of the Papillomaviridae family. The prevalence of HPV genotypes may vary according to the region and the population studied. Quilombo communities are ethnic and racial groups with difficult access to health services compared to the general population in Brazil. The aim of this study was to identify specific HPV types correlating with sociodemographic/behavioral characteristics and cervical smear cytological abnormalities in Quilombola women. METHODS: This cross-sectional study included 395 Quilombola women users of the Unified Health System of the Municipalities of Maranhão for the screening of cervical cancer. The samples were analyzed for the presence of cytological abnormalities by conventional methods and tested for 37 HPV genotypes using polymerase chain reaction with primers PGMY09/11 followed by reverse line blot hybridization performed with the Linear Array HPV Genotyping Test kit by Roche Molecular System®. The association between HPV types and cytological diagnosis was investigated according to the different age groups. RESULTS: HPV infection was detected in 12.6% (50/395) of the women. Infections by high-risk HPV types were more frequent. Genotypes 68 (26.0%); 58 and 52 (20.0%); 31 (10.0%) and 62 (8.0%) were the most prevalent. The highest prevalence (42.0%) of HPV infection occurred in women diagnosed with high-grade squamous intraepithelial lesion. There was a statistically significant association between HPV infection and the detection of cytological abnormalities in all age groups except in women over 60 years. There was a statistically significant association between the municipality of origin and the number of partners with HPV infection. CONCLUSIONS: It is important to incorporate new cervical cancer screening techniques incorporating the cervical-vaginal cytology. For further studies, it is necessary to determine the level of knowledge of Quilombola population on health-related issues including HPV infection and cervical cancer. This will contribute to the continuous improvement of healthcare coverage among the population and enhance the implementation of cancer care in the state of Maranhão.

ABSTRACT

ABSTRACT Introduction: Climacteric women are susceptible to a number of changes, among them osteoporosis. Osteoporosis is a disease characterized by low bone mass and susceptibility to fracture. Currently, this disease is a public health issue, being necessary to recognize its risk factors. Objectives: Identify risk factors related to osteoporosis in women attending Propis/Proex/UFMA, tracing a socio-demographic characterization and considering community lifestyles. Material and methods: This is a transversal retrospective clinical with a quantitative approach study conducted between March and June 2013 in São Luís (MA) with 107 women treated at the Programa de Práticas de Integralidade em Saúde (Propis - Integrality Health Practice Program). The study was approved by the University Hospital Ethics Committee of UFMA under opinion no. 362/07. Data were tabulated and analyzed in the epidemiological Epi-Info® software, version 3.4.1. Results: The brown color was predominant, consensual relationships proved to be a protective factor and low education was a risk factor. The average age of the group with menopause was 54.1 years and without menopause was 31.3 years (p < 0.0001). The average age of menopause was 43.7 years. The irregular menstrual cycle was a protective factor. The average number of pregnancies was 4.56 for the group with menopause and 2.45 for the group without menopause, with most births occurring normally (p < 0.0001). Smoking, physical inactivity and caffeine intake were risk factors, while the absence of alcoholism and of soda intake were protective factors for the disease. Conclusion: The patients followed the socioeconomic and demographic profile of Maranhão. Most had menarche and menopause in appropriate periods, showed no positive family history of osteoporosis, did not usually drink alcohol, were sedentary and the caffeine intake was high.


RESUMO Introdução: As mulheres no climatério estão suscetíveis a uma série de mudanças, entre elas a osteoporose. A osteoporose é uma doença caracterizada por uma baixa massa óssea e susceptibilidade à fratura. Atualmente, essa doença é um problema de saúde pública e é necessário reconhecer seus fatores de risco. Objetivos: Identificar os fatores de risco relacionados com a osteoporose em mulheres atendidas pelo Programa de Práticas de Integralidade em Saúde (Propis)/Proex/UFMA, traçar uma caracterização sociodemográfica e considerar o estilo de vida da comunidade. Material e métodos: Trata-se de um estudo transversal retrospectivo clínico com uma abordagem quantitativa, feito entre março e junho de 2013, em São Luís (MA), com 107 mulheres atendidas pelo Programa de Práticas de Integralidade em Saúde (Propis). O estudo foi aprovado pelo Comitê de Ética do Hospital Universitário da UFMA, sob parecer nº 362/07. Os dados foram tabulados e analisados com o software epidemiológico Epi-Info®, versão 3.4.1. Resultados: A etnia parda foi predominante, a união estável mostrou ser um fator protetor e a baixa escolaridade foi um fator de risco. A idade média do grupo com menopausa foi de 54,1 anos e a do sem menopausa de 31,3 anos (p < 0,0001). A idade média da menopausa foi de 43,7 anos. O ciclo menstrual irregular foi um fator protetor. O número médio de gestações foi de 4,56 para o grupo com menopausa e 2,45 para o grupo sem menopausa, com a maior parte dos partos normal (p < 0,0001). O tabagismo, a inatividade física e o consumo de cafeína foram fatores de risco, enquanto a ausência de alcoolismo e de ingestão de refrigerante foram fatores de proteção para a doença. Conclusão: Os pacientes seguiram o perfil socioeconômico e demográfico do Maranhão. A maior parte teve a menarca e a menopausa em períodos apropriados, não apresentava antecedentes familiares de osteoporose, não costumava ingerir bebida alcoólica, era sedentária e consumia uma elevada quantidade de cafeína.

ABSTRACT

BACKGROUND: Familial cancer includes some types of cancer aggregation without a well-defined inheritance pattern. Cancer genetics is an essential component of clinical practice in oncology. In Brazil, breast cancer is the leading cause of death in women. In Maranhão, studies on genetic predisposition are necessary to investigate the incidence and mortality rates. The aim of this study was to investigate familial cancer among relatives of women who died of breast cancer in São Luís, Brazil, constructing a pedigree to identify families with a hereditary predisposition, an important step in the early diagnosis of malignant tumors. METHODS: The city of São Luís is located on the Island of Maranhão, northeastern Brazil, with a population of 997,098 inhabitants mainly comprising blacks and mulattoes, including descendants of runaway slaves from the Amazon region itself. Data for pedigree construction were obtained from the records of 54 patients seen at the Aldenora Bello Institute of Oncology, São Luís, between 2000 and 2007, as well as by interview with relatives of the patients. RESULTS: The mean patient age at diagnosis was 39.5 years. Most women were mulattoes (36/54, 66.6%). A history of cancer was observed in 18 families, with 16 families possessing cases of cancer among first-degree relatives and five among second-degree relatives. CONCLUSION: A concentration of cancer cases was found in families of patients diagnosed until the age of 40, a finding demonstrating the importance of a family history prior to genetic counseling.

ABSTRACT

INTRODUCTION: Respiratory allergies are becoming increasingly frequent, especially based on studies of asthma and rhinitis. It is estimated that 20-30% of the world's population is affected. Allergic reactions are caused by the production of IgE antibodies specific to inhaled allergens, such as fungi in the air. This study aimed to analyze the level of specific IgE against airborne fungi in patients with a clinical diagnosis of asthma and rhinitis/sinusitis. METHODS: In total, 158 patients enrolled in the Program of Support for Asthmatic Patient, and 20 controls were studied. Clinical data from the period of 2007-2008 were surveyed using a protocol form. ELISAs were performed to quantify the levels of total and specific IgE. RESULTS: Of the 158 patients diagnosed with asthma, 71 had rhinitis and 32 had sinusitis. There was a predominance of females and residents of urban areas. The main symptoms reported were dyspnea, cough, wheezing and nasal obstruction. There was a statistically significant relationship between dyspnea and seropositivity for Fusarium (p = 0.01) and Penicillium (p = 0.005) and between cough and seropositivity for Aspergillus (p = 0.007). CONCLUSIONS: Anti-Penicillium (79.7%) and anti-Fusarium IgE (77.8%) were found to have the highest prevalence of seropositivity in individuals with asthma and rhinitis/sinusitis. Sensitivity to fungi was higher in symptomatic individuals. The identification of environmental fungi is essential for the diagnosis of respiratory allergy.

ABSTRACT

Este estudo realizou-se na cidade de São Luis, Maranhão, com a finalidade de investigar possível relação entre alergia respiratória e elevação sérica de IgE total e IgE específica para fungos isolados de ambientes externos. Métodos: Fizeram parte deste estudo 98 crianças com diagnóstico clínico de asma e/ou rinite alérgica, com idades entre 4 e 12 anos, sendo 65(66,3%) do sexo masculino e 33 (33,7%) do sexo feminino. Quantificaram-se no soro dessas crianças os níveis de IgE total e IgE específica para Aspergillus spp e Penicillium spp, pelo método de ELISA. Resultados: IgE total foi detectada em 95 crianças (96,9%); 73 (74,5%) apresentaram níveis detectáveis de IgE anti-Aspergillus spp e 85 (86,7%) de IgE anti-Penicillium spp. Não houve significância estatística quando foram correlacionados níveis de IgE total, sexo e área de residência das crianças estudadas (p = 0,88). Na correlação entre IgE total e faixa etária verificou-se distribuição não normal dos dados, com destaque à faixa etária de 11 anos, onde os níveis deIgE total foram mais elevados (Teste de Shapiro p < 0,05). Não houve correlação entre IgE anti-Aspergilluse IgE anti-Penicillium com idade, sexo e área de residência. Conclusão: Anticorpos IgE contra os fungos estudados possivelmente fazem parte de uma polissensibilização, já que os fungos estão presentes em todas as áreas e durante todo o ano na cidade de São Luis, Maranhão, Brasil. Serão necessários mais estudos para o entendimento da alergia respiratória por fungos do ar em São Luis, Maranhão...


The present study was carried out in the city of São Luís, capital of the state of Maranhão, northeastern Brazil, with the aim of investigating a possible relationship between respiratory allergies and high serum levels of total IgE and specific IgE for fungi isolated in outdoor environments. Methods: The study included 98 children with a clinical diagnosis of asthma and/or allergic rhinitis, aged 4 to 12 years. Sixty-five (66.3%) were male and 33 (33.7%) female. Total IgE, Aspergillus spp-specific IgE, and Penicillium spp-specific IgE were quantified in the serum of the children using the ELISA method. Results: Total IgE was detected in 95 children (96.9%). Seventy-three (74.5%) showed detectable levels of Aspergillus spp-specific IgE, and 85 (86.7%), of Penicillium spp-specific IgE. There was no significant correlation between total IgE levels, sex, and area of residence among the children assessed (p = 0.88). When assessing the correlation between total IgE levels and age, data were found to have a non-normal distribution, especially in the 11-year old age group, where total IgE levels were higher than in the other ages (Shapiro test, p < 0.05). There was no significant correlation of Aspergillus spp- and Penicillium spp-specific IgE with age, gender, and area of residence. Conclusion: IgE antibodies against the fungi investigated are possibly a part of polysensitization, as these fungi are present in all areas and throughout the year in the city investigated. Further studies are necessary for a better understanding of the role played by fungal sensitization in respiratory allergy in São Luís, Maranhão...

ABSTRACT

Introduction: This study aimed to identify airborne fungi in São Luis, Maranhão, Brazil, to determine the prevalent genera and to correlate these genera with the area and season. Methods: In total, 1,510 colony-forming units (CFUs) of airborne fungi were isolated from the north, south, east and west sides and from the center of the city from January to December 2007. The samples were collected on Petri dishes that were exposed to the fungi by the gravitational method. Results: Twenty genera of fungi were isolated; the most common were Aspergillus (33.5%), Penicillium (18.8%), Cladosporium (14.2%), Curvularia (10.6%) and Fusarium (7.6%). The CFUs of the fungi were statistically significant (p < 0.0001). Fungal biological diversity was present all year, without any large seasonal variations but with slight increases in May, August and September. Conclusions: The fungal genera identified in this study were correlated with natural systems and could be useful when evaluating the impact of environmental changes on the region. .

ABSTRACT

Introduction: There are more than 300,000 extractors using the babaçu coconut as a source of income in the States of Maranhão, Pará, Tocantins and Piauí, and this activity is associated with fungal infections. The objective of this study was to examine the occurrence of emergent fungi in the conjunctiva, nails and surface and subcutaneous injuries of female coconut breakers in Esperantinópolis, Maranhão. Additionally, soil samples and palm structures were collected. Methods: The obtained samples were cultured in Petri dishes containing potato-dextrose-agar and chloramphenicol. The etiological agent was confirmed by a direct mycological exam and growth in culture. Results: In total, 150 domiciles were visited, and samples were collected from 80 patients. From the ground, the most frequently isolated fungus was Aspergillus niger (53. 8%). the most frequently detected fungus in babaçu coconut was Aspergillus niger (66.7%). Conjunctival fungal growth occurred in 76.3% of the women. The ocular fungal microbiota consisted of filamentous fungi (80.6%), and yeasts were present in 19.4% of cases. Onychomycosis was diagnosed in 44% (11/25) of the women. Conclusions: The identification of the genera Neosartorya, Rhizopus and Curvularia in onychomycoses shows that emergent filamentous fungi can be isolated. Aspergillus sp., Penicillium sp. and Scedosporium sp. were the predominant genera found in the babaçu coconut. From ocular conjunctiva, Candida spp. were the most prevalent species isolated, and Fusarium sp. was present only in one woman. The nearly permanent exposure of coconut breakers to the external environment and to the soil is most likely the reason for the existence of a mycotic flora and fungal infections, varying according to the individual's practices and occupation. .

ABSTRACT

Os tumores filoides são neoplasias fibroepiteliais raras de mama. Em sua forma menos agressiva, comportam-se semelhantemente ao fibroadenoma, diferenciando-se apenas pelo tamanho do tumor e/ou velocidade do crescimento. Relatou-se um caso de uma menor de idade, apresentando ginecomastia bilateral, submetida à mastectomia esquerda e quadrantectomia na mama direita. O diagnóstico anatomopatológico demonstrou proliferação estromal, compatível com tumor filoide, o que comprometeu toda a extensão das peças cirúrgicas, inclusive a pele da região areolar. O diagnóstico de tumor filoide é raro nas mamas de adolescentes. O caso relatado adquire grande importância em função da idade da paciente, da localização e da extensão da lesão.


Phyllodes tumors are rare fibroepithelial breast neoplasms. In a less aggressive form, they behave in a similar fashion to the fibroadenoma, and the only differences can be seen in the tumor size and/or speed of growth. We reported the case of an underage girl, with bilateral gynecomastia, who underwent left mastectomy and right breast quadrantectomy. The histopathological diagnosis showed stromal proliferation, consistent with phyllodes tumor that compromised the entire length of the surgical specimens, including the skin areolar region. Diagnosis of phyllodes tumor is rare in breasts of adolescents. The reported case is of great importance due to the patient?s age, and location and extent of the injury
