ABSTRACT Introduction: Pulse wave velocity is used to diagnose central arterial stiffness (CAS) and quantify healthy vascular aging (HVA). Objective: To evaluate the CAS and HVA in elderly patients with systemic blood pressure levels classified as optimal/normal. Methods: A total of 102 patients without comorbidities and with systolic pressure (SP) < 120 mmHg and diastolic pressure (DP) < 80 mmHg were selected from the EVOPIU database (Pulse Wave Velocity of Elderly Individuals in an Urban area of Brazil). The carotid-femoral pulse wave velocity (c-fPWV) and the central and peripheral pressures were evaluated in all patients. The patients were divided into four groups: G1: (n = 19, with c-fPWV < 7.6 m/s, without medication), G2 (n = 26, c-fPWV ≥ 7.6 m/s; without medication), G3 (n = 25, c-fPWV < 7.6 m/s with antihypertensive medication), and G4 (n = 32, c-fPWV ≥ 7.6 m/s with antihypertensive medication). Results: In our sample, 56.7% of patients had c-fPWV ≥ 7.6 m/s. The central systolic pressure in G1 [99 (10) mmHg] was lower than that found in the other three groups [vs. 112 (14) mmHg, 111 (15), 112 (20) mmHg; P < 0.05)]. Conclusion: Older people with optimal arterial blood pressure do not necessarily have HVA and could have c-fPWV values close to the limits established for CAS diagnosis.

RESUMO Introdução: A velocidade da onda de pulso é usada para diagnosticar a rigidez arterial central (RAC) e quantificar o envelhecimento vascular saudável (EVS). Objetivo: Avaliar a RAC e o EVS em pacientes idosos com níveis pressóricos sistêmicos classificados como ideais/normais. Métodos: Um total de 102 pacientes sem comorbidades e com pressão sistólica (PS) < 120 mmHg e pressão diastólica (PD) < 80 mmHg foram selecionados do banco de dados EVOPIU (Estudo da Velocidade de Onda de Pulso em Idosos em área Urbana no Brasil). Foram avaliadas a velocidade da onda de pulso carotídeo-femoral (VOPcf) e as pressões central e periférica em todos os pacientes. Os pacientes foram divididos em quatro grupos: G1: (n = 19; com VOPcf < 7,6 m/s; sem medicação), G2 (n = 26; VOPcf ≥ 7,6 m/s; sem medicação), G3 (n = 25; VOPcf < 7,6 m/s com medicação anti-hipertensiva), e G4 (n = 32; VOPcf ≥ 7,6 m/s com medicação anti-hipertensiva). Resultados: Em nossa amostra, 56,7% dos pacientes apresentaram VOPcf ≥ 7,6 m/s. A pressão sistólica central no G1 [99 (10) mmHg] foi inferior à encontrada nos outros três grupos [vs. 112 (14) mmHg, 111 (15), 112 (20) mmHg; P < 0,05)]. Conclusão: Pessoas idosas com pressão arterial ideal não necessariamente têm EVS e podem apresentar valores de VOPcf próximos aos limites estabelecidos para o diagnóstico de RAC.

RESUMO Estresses abióticos associados causam efeitos e respostas diferentes da exposição a uma única fonte de estresse. Objetivou-se avaliar o efeito do estresse combinado de temperatura supraótima e déficit hídrico no processo germinativo de lotes de sementes de trigo com diferentes níveis de vigor. Sementes de trigo IPR Catuara de quatro lotes foram submetidas a germinação nos potenciais hídricos 0,000, - 0,075, - 0,223 e - 0,444 MPa, associados às temperaturas 20, 24, 28 e 32 ºC, totalizando 16 combinações de estresse. O delineamento experimental foi inteiramente casualizado, com quatro repetições, em esquema fatorial: quatro lotes x 16 combinações de estresse, e comparação de médias por Scott-Knott 5%. Avaliaram-se a germinação das plântulas normais aos quatro e oito dias, o conteúdo de proteína total e a atividade da catalase e ascorbato peroxidase (APX) na parte aérea e radicular das plântulas. As análises de componentes principais e de agrupamento hierárquico foram aplicadas à matriz original formada pelas 16 combinações, para a média dos quatro lotes. Sementes de trigo de maior vigor são mais tolerantes a combinação dos estresses hídrico e térmico. Não há prejuízo ao processo germinativo de trigo nas combinações sob temperaturas supraótimas até 28 °C e redução dos potenciais hídricos até -0,223 MPa. Independente da temperatura, o potencial hídrico -0,444 MPa diminui a porcentagem e a velocidade da germinação. A atividade da APX aumenta em condições de estresses hídrico e térmico atuando como defesa ao estresse oxidativo na germinação de trigo.

ABSTRACT Combined abiotic stresses have different effects and responses than exposure to a single source of stress. The objective of this study was to evaluate the effect of the combined stress of supra-optimal temperatures and water deficit on the germination of wheat seeds with different levels of vigor. Wheat seeds from four different lots of the IPR Catuara cultivar were germinated at water potentials of 0.000, -0.075, -0.223, and -0.444 MPa, associated with temperatures of 20 °C, 24 °C, 28 °C, and 32 °C, totaling 16 stress combinations. The experimental design was completely randomized in a factorial scheme with four replications (four seed lots × 16 stress combinations), and means were compared using Scott-Knott 5%. We evaluated the germination of normal seedlings at 4 and 8 d, the activity of catalase and ascorbate peroxidase (APX), and the protein content of the aerial and root parts of wheat seedlings. Principal components analysis and hierarchical clustering were applied to the original matrix formed by the 16 combinations for the average of the four lots. Wheat seeds with higher vigor were more tolerant to combined water and thermal stress. Temperatures up to 28 °C and reduction of water potentials down to -0.223 MPa did not prejudice the germination process of wheat seeds. Regardless of temperature, a water potential of -0.444 MPa decreased the percentage and rate of germination. APX activity increased under water stress and supra-optimal temperatures, acting as a defense mechanism against oxidative stress.

Abstract Continuous development, improvement and innovation of ballistic material systems with superior energy absorption performance has been the subject of numerous works nowadays. Some research has been carried out with the objective of replacing traditional metallic and ceramic materials and composites with high-performance polymeric composites. Due to their excellent properties, multi-scale polymer composites have been used in the most varied segments of the industry, being recently researched in applications such as ballistic materials. This work promotes the combination of high-strength three-dimensional woven aramid fiber fabrics with vinyl ester resin to produce a panel through the compression molding process. The resin was reinforced with graphene nanoplatelets (0.1, 0.2 and 0.3% wt). The impact, tensile and flexural strength were evaluated, along with dynamic-mechanical analysis by DMA and by Hopkinson split bar test, indicating a trend of better performance for the composite containing 0.1% of graphene nanoplatelets.

ABSTRACT Objective To translate and cross-culturally adapt the Noise Exposure Questionnaire (NEQ) and 1-Minute Noise Screen (NEQ-S) instruments to Brazilian Portuguese. Methods Procedures widely known in health research were used in the translation and cross-cultural adaptation process, comprising the following steps: initial translation, synthesis of translations, back-translation, expert committee, pretest, and content and layout validation. Altogether, 60 workers participated in the pretest by answering the questionnaires and then evaluating them in terms of understandability, layout, clarity, and writing. Reliability was verified with Cohen's kappa test, and the internal consistency was analyzed with Cronbach’s alpha coefficient. Results The translated and adapted versions of NEQ and NEQ-S were similar in terms of general and referential meanings. However, some modifications and adaptations were made to adapt them to the Brazilian reality. The kappa test indicated moderate agreement and Cronbach’s alpha coefficient, substantial internal consistency. Conclusion The translation and cross-cultural adaptation were carried out according to the methodology recommended in the national and international literature, performing the necessary equivalences to maintain the face and content validity with the original instrument. The availability of NEQ and NEQ-S in Brazilian Portuguese opens new fields of research to quantify yearly noise exposure more in-depth.

RESUMO Objetivo Traduzir e realizar a adaptação transcultural dos instrumentos Noise Exposure Questionnaire (NEQ) e 1-Minute Noise Screen (NEQ-S) para a versão em português brasileiro. Método O processo de tradução e adaptação transcultural seguiu procedimentos amplamente utilizados em pesquisas da área da saúde, compostos pelas seguintes etapas: tradução inicial, síntese das traduções, retrotradução, comitê de especialistas, pré-teste, e validação do conteúdo e aparência. Na etapa de pré-teste, participaram 60 trabalhadores, que responderam aos questionários e, posteriormente, os avaliaram quanto ao: entendimento, aparência, clareza e escrita. Para a verificação da confiabilidade, foi utilizado o teste kappa de Cohen e para a análise da consistência interna foi aplicado o coeficiente alfa de Cronbach. Resultados As versões traduzidas e adaptadas dos questionários NEQ e NEQ-S mostraram-se semelhantes em relação ao significado geral e referencial. Entretanto, algumas modificações e adaptações foram realizadas, para adequação à realidade brasileira. O teste kappa indicou concordância moderada e o coeficiente alfa de Cronbach, consistência interna substancial. Conclusão A tradução e a adaptação transcultural foram realizadas de acordo com a metodologia preconizada na literatura nacional e internacional, incluindo-se as equivalências necessárias para a manutenção da validade de face e conteúdo com o instrumento original. A disponibilização dos questionários NEQ e NEQ-S na versão da língua portuguesa brasileira abre novos campos de pesquisa para aprofundamento da quantificação de exposição anual ao ruído.

Resumo Objetivo Determinar a prevalência e as possíveis variáveis associadas à neoplasia intraepitelial anal e ao câncer anal em mulheres imunocompetentes com neoplasia intraepitelial cervical de alto grau. Métodos Estudo transversal em mulheres imunocompetentes com diagnóstico histológico de neoplasia intraepitelial cervical de alto grau e câncer cervical, feito entre janeiro de 2016 e setembro de 2020. Todas as mulheres foram submetidas a citologia anal e responderam a um questionário de caracterização e potenciais fatores de risco. Mulheres com citologia alterada foram submetidas a anuscopia e biópsia. Resultados No total, 69 mulheres foram incluídas no estudo. Destas, 7 (10,1%) tiveram resultados anormais de citologia anal (lesão de alto grau, células escamosas atípicas de significado indeterminado, e células escamosas atípicas, não se pode excluir lesões de alto grau: 28,5% cada; lesão de baixo grau: 14,3%). Das anuscopias, 3 (42,8%) demonstraram alterações. Das 2 biópsias realizadas, apenas 1 apresentou neoplasia intraepitelial anal de baixo grau. O número médio de gestações, partos vaginais e abortos estava associado à citologia anal anormal. No entanto, a maior média de partos cesáreos estava associada à citologia normal. Conclusão A prevalência de neoplasia intraepitelial anal foi compatível com dados de estudos recentes, principalmente daqueles feitos no Brasil. O rastreamento oportunista para neoplasia intraepitelial anal nesta população de alto risco deve ser considerado. A citologia anal é adequada para esse fim, devido ao seu baixo custo e viabilidade nos serviços públicos de saúde.

Abstract Objective To determine the prevalence and possible variables associated with anal intraepithelial neoplasia and anal cancer in immunocompetent women with high-grade cervical intraepithelial neoplasia. Methods A cross-sectional study involving immunocompetent women with a histological diagnosis of high-grade cervical intraepithelial neoplasia and cervical cancer, conducted between January 2016 and September 2020. All women underwent anal cytology and answered a questionnaire on characterization and potential risk factors. Women with altered cytology were submitted to anoscopy and biopsy. Results A total of 69 women were included in the study. Of these, 7 (10.1%) had abnormal anal cytology results: (high-grade lesion, atypical squamous cells of undetermined significance, and atypical squamous cells, cannot exclude high-grade lesions: 28,5% each; low grade lesion: 14,3%). Of the anoscopies, 3 (42.8%) showed alterations. Of the 2 (28,5% of all abnormal cytology results) biopsies performed, only 1 showed low-grade anal intraepithelial neoplasia. The average number of pregnancies, vaginal deliveries, and abortions was associated with abnormal anal cytology. However, the highest mean regarding the cesarean sections was associated with normal cytology. Conclusion The prevalence of anal intraepithelial neoplasia was compatible with data from recent studies, especially those conducted in Brazil. Opportunistic screening for anal intraepithelial neoplasia in this high-risk population should be considered. Anal cytology is suitable for this purpose, due to its low cost and feasibility in public health services.

Abstract: En | Text: En | PDF: En

SUMMARY OBJECTIVE: The polycystic ovary syndrome is the most common endocrine disorder, characterized by the dysregulation of ovarian angiogenesis. This alteration can be related to changes in the activities of the vascular endothelial growth factor (VEGF) gene. Single-nucleotide polymorphisms have been observed in the promoter, intronic, and untranslated regions of the VEGF gene, and several studies have suggested that these polymorphisms may be associated with the risk of polycystic ovary syndrome. This study aimed to investigate the association between rs2010963 and rs833061 polymorphisms and haplotypes of VEGF in the etiology of polycystic ovary syndrome. METHODS: A total of 210 women, 102 diagnosed with polycystic ovary syndrome and 108 controls, participated in this study. The genotyping of the samples was performed by PCR-RFLP and real-time PCR for rs2010963 and rs833061 polymorphisms, respectively. The statistical analyses were performed by the chi-square test and logistic regression model. RESULTS: The clinical characteristics of the patients showed that 75.8% of the patients did not become pregnant, 36.3% had a family history of polycystic ovary syndrome, 58.6% were obese, and about 60% had clinical characteristics of hyperandrogenism. There were no associations between the distribution of rs2010963 (OR 1.24; 95%CI 0.60–2.57; p=0.56) and rs833061 (OR 0.78; 95%CI 0.32–1.92; p=0.59) in patients and controls. CONCLUSIONS: The patients with polycystic ovary syndrome have similar rates of VEGF polymorphisms rs2010963 and rs833061 on the general population.

ABSTRACT Cachaça is a typical Brazilian spirit of significant economic and social relevance. The spirit may contain organic and inorganic contaminants that impair its quality, such as ethyl carbamate (EC), which is potentially carcinogenic. The study of factors that cause EC incidence is extremely important to produce cachaça with good physicochemical and sensory quality and for public health reasons. Therefore, this study aimed to analyze and quantify nitrogen (N) in sugarcane juice and correlate it with the EC levels, with copper (Cu) as precursor, in cachaça from stills, produced from the sugar of three different sugarcane varieties (RB857515, RB966928 and RB855453). We used the plantation systems without fertilization and with organic and conventional fertilization. The EC and Cu levels were below the legislation threshold and the N levels were correlated with EC formation in different planting systems.

RESUMO O DC de Neuroimunologia da ABN e o BCTRIMS trazem, nesse documento, as recomendações sobre vacinação da população com doenças desmielinizantes do sistema nervoso central (SNC) contra infecções em geral e contra o coronavírus da síndrome respiratória aguda grave 2 (SARS-CoV-2), causador da COVID-19. Destaca-se a gravidade do atual momento frente ao avanço da COVID-19 em nosso País, o que torna mais evidente e importante a criação de guia de referência para orientação aos médicos, pacientes e autoridades de saúde pública quanto à vacinação, meio efetivo e seguro no controle de determinadas doenças infecciosa. O DCNI/ABN e o BCTRIMS recomendam que os pacientes com doenças desmielinizantes do SNC (ex., EM e NMOSD) sejam constantemente monitorados, quanto a atualização do seu calendário vacinal, especialmente, no início ou antes da mudança do tratamento com uma droga modificadora de doença (DMD). É importante também salientar que as vacinas são seguras e os médicos devem estimular o seu uso em todos os pacientes. Evidentemente, deve ser dada especial atenção às vacinas com vírus vivos atenuados. Por fim, é importante que os médicos verifiquem qual DMD o paciente está em uso e quando foi feita a sua última dose, pois cada fármaco pode interagir de forma diferente com a indução da resposta imune.

ABSTRACT The Scientific Department of Neuroimmunology of the Brazilian Academy of Neurology (DCNI/ABN) and Brazilian Committee for Treatment and Research in Multiple Sclerosis and Neuroimmunological Diseases (BCTRIMS) provide recommendations in this document for vaccination of the population with demyelinating diseases of the central nervous system (CNS) against infections in general and against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes COVID-19. We emphasize the seriousness of the current situation in view of the spread of COVID-19 in our country. Therefore, reference guides on vaccination for clinicians, patients, and public health authorities are particularly important to prevent some infectious diseases. The DCNI/ABN and BCTRIMS recommend that patients with CNS demyelinating diseases (e.g., MS and NMOSD) be continually monitored for updates to their vaccination schedule, especially at the beginning or before a change in treatment with a disease modifying drug (DMD). It is also important to note that vaccines are safe, and physicians should encourage their use in all patients. Clearly, special care should be taken when live attenuated viruses are involved. Finally, it is important for physicians to verify which DMD the patient is receiving and when the last dose was taken, as each drug may affect the induction of immune response differently.

RESUMO Os canabinoides compreendem os endocanabinoides, fitocanabinoides e os canabinoides sintéticos e desempenham ações no sistema nervoso central e periférico. Uma quantidade enorme de publicações tem sido lançada nos últimos anos, embora a cannabis seja conhecida por milênios. Os Departamentos Científicos da Academia Brasileira de Neurologia descreveram as evidências do uso médico em suas áreas. A literatura está em constantes mudanças e possíveis novas evidências podem surgir nos próximos dias ou meses. A prescrição dessas substâncias deve ser discutida com os pacientes e suas famílias, com conhecimento sobre eventos adversos e sua eficácia.

ABSTRACT Cannabinoids comprehend endocannabinoids, phytocannabinoids, and synthetic cannabinoids, with actions both in the central and peripherical nervous systems. A considerable amount of publications have been made in recent years, although cannabis has been known for over a thousand years. Scientific Departments from the Brazilian Academy of Neurology described evidence for medical use in their areas. Literature is constantly changing, and possible new evidence can emerge in the next days or months. Prescription of these substances must be discussed with patients and their families, with knowledge about adverse events and their efficacy.

Resumo Objetivo identificar fatores associados ao enfrentamento da pandemia da COVID-19 por pessoas idosas com e sem comorbidades. Método estudo descritivo, transversal, com pessoas idosas (n=569), entre 60 e 80 anos, com ou sem comorbidades, nas cinco regiões do Brasil. Coleta de dados com questionário virtual e análise com base na estatística descritiva e inferencial. Resultados os resultados mostram que 351, (61,68%), referem comorbidade. Houve associação significativa entre os grupos nas variáveis: faixa etária (p=0,017), realizar alguma atividade laboral (p≤0,001), pensamento da possibilidade de ser infectado pelo novo coronavírus (p≤0,001), concordar com medidas de prevenção adotadas para o distanciamento social (p≤0,001), se informar por outro meio de comunicação além da televisão (p≤0,001). Conclusão e implicações para a prática os idosos com comorbidades pensam na possibilidade de ser infectado pelo novo coronavírus, concordam mais com as medidas de distanciamento social e se informam mais. Nesse sentido, indica-se a realização de pesquisas com ênfase nos idosos sem comorbidade, para direcionar melhor os cuidados de saúde em tempos de pandemias.

Abstract Objective to identify factors associated to coping with the COVID-19 pandemic by older adults with and without comorbidities. Method a descriptive, cross-sectional study with older adults (n=569), aged between 60 and 80 years old, with or without comorbidities, in the five Brazilian regions. Data collection with virtual questionnaire and analysis based on descriptive and inferential statistics. Results the results show that 351 (61.68%) refer to comorbidity. There was a significant association between the groups in the following variables: age group (p=0.017), performing some work activity (p≤0.001), thinking about the possibility of being infected by the new coronavirus (p≤0.001), agreeing with prevention measures adopted for social distancing (p≤0.001), informing yourself by other means of communication besides television (p≤0.001).

Resumo Introdução: A osteoartrite de joelho (OJ) é uma doença degenerativa e inflamatória que causa incapacidade musculoesquelética, acarretando limitação de atividades funcionais como a marcha. Objetivo: Avaliar a relação entre velocidade da marcha e desempenho funcional em idosas com OJ. Métodos: Trinta e oito idosas foram divididas em grupo com osteoartrite de joelho (GOAJ) (n = 24, 68 ± 4,42) e grupo controle (GC) (n = 14, 66,35 ± 3,54) e avaliadas quanto à velocidade da marcha, utilizando o sistema Qualisys, e quanto ao desempenho funcional através de um checklist da Classificação Internacional de Funcionalidade, Incapacidade e Saúde (CIF). Resultados: GOAJ apresentou menor velocidade da marcha (p = 0,004) e pior desempenho funcional nas categorias da CIF d4500 (andar distâncias curtas), d4501 (andar distâncias longas), d4502 (andar em superfícies diferentes) e d4503 (andar contornando obstáculos) em comparação ao GC (p < 0,05). Ao associar velocidade da marcha e desempenho funcional do GOAJ, encontrou-se diferenças nas categorias d4500 (p = 0,019) e d4501 (p = 0,035), mas não em relação às categorias d4502 (p = 0,511) e d4503 (p = 0,076). Velocidade da marcha correlacionou-se negativamente com d4500 (rho = - 0,585, p = 0,003), d4501 (rho = -0,552, p = 0,005) e d4502 (rho = -0,548, p = 0,006). Conclusão: Existe relação entre velocidade da marcha e desempenho funcional de idosas com OJ quanto às atividades de andar distâncias curtas e longas e sobre superfícies diferentes; no entanto, a velocidade da marcha parece não interferir na atividade de andar contornando obstáculos.

Abstract Introduction: Knee osteoarthritis is a degenerative and inflammatory disease that causes skeletal muscle dysfunction and induces limitation of functional activities, such as gait. Objective: To assess the relationship between gait speed and functional performance in elderly women with knee osteoarthritis. Methods: 38 elderly women were divided into two groups: knee osteoarthritis group (KOAG) (n = 24, 68 ± 4.42) and control group (CG) (n = 14, 66.35 ± 3.54). Gait speed data was assessed through Qualisys system and functional performance through a checklist of the International Classification of Functioning, Disability and Health (ICF). Results: Comparing with CG (p < 0.05), KOAG patients had lower gait speed (p = 0.004) and worse functional performance in d4500 (walking short distances), d4501 (walking long distances), d4502 (walking on different surfaces), and d4503 (walking around obstacles) ICF categories. By associating gait speed and functional performance in KOAG, significant differences were found in the d4500 (p = 0.019) and d4501 (p = 0.035) categories, but none for either the d4502 (p = 0.511) or d4503 (p = 0.076) categories. Gait speed was negatively correlated with d4500 (rho = -0.585, p = 0.003), d4501 (rho= -0.552, p = 0.005), and d4502 (rho = -0,548, p = 0,006). Conclusion: Gait speed is related to functional performance in elderly women with knee osteoarthritis for the activities of walking short distances, walking long distances, and walking on different surfaces. However, it seems that gait speed is not related to walking around obstacles.

Abstract Coronavirus disease 2019 (COVID-19), caused by the Severe Acute Respiratory Syndrome Coronavirus type 2 (SARS-CoV-2), is the largest pandemic in modern history with very high infection rates and considerable mortality. The disease, which emerged in China’s Wuhan province, had its first reported case on December 29, 2019, and spread rapidly worldwide. On March 11, 2020, the World Health Organization (WHO) declared the COVID-19 outbreak a pandemic and global health emergency. Since the outbreak, efforts to develop COVID-19 vaccines, engineer new drugs, and evaluate existing ones for drug repurposing have been intensively undertaken to find ways to control this pandemic. COVID-19 therapeutic strategies aim to impair molecular pathways involved in the virus entrance and replication or interfere in the patients’ overreaction and immunopathology. Moreover, nanotechnology could be an approach to boost the activity of new drugs. Several COVID-19 vaccine candidates have received emergency-use or full authorization in one or more countries, and others are being developed and tested. This review assesses the different strategies currently proposed to control COVID-19 and the issues or limitations imposed on some approaches by the human and viral genetic variability.

RESUMO OBJETIVO: Este estudo teve como objetivo investigar os polimorfismos de deleção dos genes da família glutationa S-transferase GSTT1 e GSTM1 em pacientes com síndrome dos ovários policísticos (SOP), comparando-as com uma população controle. MÉTODOS: Foi colhido sangue de 219 mulheres (110 com SOP e 109 controles) e extraído o DNA genômico. Para análise dos polimorfismos, a técnica empregada foi PCR multiplex. Na análise estatística foi utilizado o teste do qui-quadrado e regressão logística múltipla. RESULTADOS: Não há associação dos genótipos GSTM1 nulo e GSTT1 nulo com SOP quando analisados isoladamente (p=0,616 e p=0,188). A análise dos genótipos combinados mostrou diferenças entre os grupos (p<0,05), evidenciando que a combinação genotípica GSTT1 positivo e GSTM1 negativo é mais frequente entre as pacientes. Na análise multivariada, o hábito tabagista foi mais frequente no grupo controle (OR=0,22; IC 95% - 0,87-0,57; p=0,002), enquanto que a presença do histórico de SOP familiar (OR=2,96; IC 95% - 1,54-5,68; p=0,001) foi mais frequente nas mulheres com SOP. CONCLUSÕES: Na casuística estudada, os polimorfismos de deleção dos genes GSTT1 e GSTM1 isolados não estão associados a SOP, mas em combinação podem estar implicados na etiologia da condição.

SUMMARY BACKGROUND: This study aimed to investigate the deletion polymorphisms of the genes of the glutathione S-transferase family GSTT1 and GSTM1 in patients with Polycystic Ovarian Syndrome (PCOS), comparing them with a control population. METHODS: Blood was collected from 219 women (110 with PCOS and 109 controls) and genomic DNA was extracted. For the analysis of polymorphisms, the technique used was multiplex PCR. In the statistical analysis, the chi-square test and multiple logistic regression were used. RESULTS: There is no association between the GSTM1 null and GSTT1 null genotypes with PCOS when analyzed separately (P = 0.616 and P = 0.188). The analysis of the combined genotypes showed differences between the groups (P < 0.05), evidencing that the genotypic combination GSTT1 positive and GSTM1 negative is more frequent among patients. In the multivariate analysis, smoking was more frequent in the control group (OR = 0.22; 95% CI - 0.87-0.57; P = 0.002) while the presence of a family history of PCOS (OR = 2, 96; 95% CI - 1.54-5.68; P = 0.001) was more frequent in women with PCOS. CONCLUSIONS: In the studied sample, the deletion polymorphisms of the GSTT1 and GSTM1 genes isolated are not associated with PCOS, but in combination, they may be implicated in the etiology of the condition.

RESUMO OBJETIVO: Este estudo teve como objetivo investigar a frequência do polimorfismo de inserção (I)/ deleção (D) do gene VEGF (rs35569394) em pacientes com Síndrome dos Ovários Policísticos (SOP) e comparar com uma população controle para verificar sua associação com a patologia. MÉTODOS: Participaram desse estudo 206 mulheres sendo 103 com SOP (grupo de pacientes) e 103 sem a doença (grupo controle). Após extração do DNA genômico das amostras, a análise molecular foi realizada por Reação em Cadeia da Polimerase e eletroforese em gel de poliacrilamida. Utilizou-se análise descritiva, análise univariada e modelo de regressão logística. Os resultados foram apresentados em odds ratio (OR) e intervalo de confiança de 95% (IC-95%), considerando a significância de p < 0,05. RESULTADOS: Não houve diferenças estatísticas entre as pacientes e controles para as frequências alélicas (χ2 = 1,16, p = 0,56). A distribuição da frequência genotípica estava em equilíbrio de Hardy Weinberg para as pacientes (χ2= 2,42; p<0,12), mas não para o grupo controle (χ2= 7,26; p<0,05). Em relação aos fatores de risco para a síndrome, a história de SOP familiar é mais frequente entre as mulheres com a síndrome. CONCLUSÕES: Na casuística estudada, não há associação entre o polimorfismo I/D do gene da VEGF e a SOP.

SUMMARY OBJECTIVE: The relationship between the clinicopathological and sociodemographics characteristics of acral melanomas diagnosed at BACKGROUND: This study aimed to investigate the frequency of VEGF gene insertion (I) / deletion (D) polymorphism (rs35569394) in patients with Polycystic Ovarian Syndrome (PCOS) and to compare with a control population to verify its association with the pathology. METHODS: 206 women participated in this study, 103 with PCOS (group of patients) and 103 without the disease (control group). After extraction of genomic DNA from the samples, molecular analysis was performed by Polymerase Chain Reaction (PCR) and electrophoresis in polycrylamide. Descriptive analysis, univariate analysis and logistic regression model were used. Results were presented in odds ratio (OR) and 95% confidence interval (95% CI), considering the significance of p <0.05. RESULTS: There were no statistical differences between patients and controls for allele frequencies (χ2 = 1.16, p = 0.56). The genotypic frequency distribution was in Hardy Weinberg equilibrium for the patients (χ2 = 2.42; p <0.05), but not for the control group (χ2 = 7.26; p <0.05). Regarding risk factors for the syndrome, a history of familial PCOS is more frequent among women with the syndrome. CONCLUSIONS: In the present study, there is no association between VEGF gene I / D polymorphism and PCOS.
