The aim of this study was to investigate eosinophiluria, urinary eosinophil cationic protein (uECP) and urinary IL-5 (uIL-5) in patients with Lupus Nephritis. Methods: Seventy-four patients with SLE—20 with clinical and laboratory evidence of lupus nephritis (LN group) and 54 without evidence of renal involvement (non-LN group)—were analyzed regarding eosinophiluria, uECP and uIL-5. Eosinophiluria was observed by Hansel's stain, ECP by fluoroenzymeimmunoassay and uIL-5 by quantitative sandwich enzyme immunoassay. Both uECP and urinary IL-5 (uIL-5) were corrected by urinary creatinine. Eosinophiluria and uECP were compared with glomerular erythrocyturia, protein/creatinine ratio (Pr/Cr ratio), serum creatinine, estimated glomerular filtration rate (eGFR), anti-double-stranded DNA (anti-dsDNA), serum levels of complement (C3 and C4), uIL-5/Cr ratio, and SLE disease activity index. Results: Patients of the LN group had higher eosinophiluria, uECP, uECP/Cr ratio levels, and uIL-5 than patients of the non-LN group (p<0.001 for all). These variables showed a statistically significant correlation with glomerular erythrocyturia, casts, Pr/Cr ratio, serum creatinine, eGFR, anti-dsDNA, uIL-5/Cr, and SLE disease activity index (all p<0.05). Conclusion: These results provide evidence of increased urinary eosinophils, ECP and IL-5 in patients with SLE and LN; uECP/Cr ratio showed better correlation with markers of renal function and SLE disease activityArtigo Circulating miRNAs in acute new-onset atrial fibrillation and their target mRNA network(Wiley Online Library, 2018) Sousa, Júlio César Vieira de; Silva, Ananília Medeiros Gomes da; Araújo, Jessica Nayara Gomes de; Oliveira, Katiane Macedo de; Novaes, Ana Eloisa Melo; Lopes, Mariana Borges; Araújo Filho, Antonio Amorim de; Luchessi, Andre Ducati; Rezende, Adriana Augusto de; Hirata, Mario Hiroyuki; Silbiger, Vivian Nogueira; https://orcid.org/0000-0001-6913-4224MicroRNAs (miRNAs) are involved in the pathogenesis of atrial fibrillation (AF), acting on development and progression. Our pilot study investigated the expression of six miRNAs and their miRNA–mRNA interactions in patients with acute new-onset AF, well-controlled AF, and normal sinus rhythm (controls). Methods and results Plasma of acute new-onset AF patients (n = 5) was collected in the emergency room when patients presented with irregular and fast-atrial fibrillation rhythm. Samples from well-controlled AF (n = 16) and control (n = 15) patients were collected during medical appointments following an ECG. Expression of miR-21, miR-133a, miR-133b, miR-150, miR-328, and miR-499 was analyzed by real-time PCR. Ingenuity Pathway Analysis and the TargetScan database identified the top 30 mRNA targets of these miRNA, seeking the miRNA–mRNA interactions in cardiovascular process. Increased expression of miR-133b (1.4-fold), miR-328 (2.0-fold), and miR-499 (2.3-fold) was observed in patients with acute new-onset AF, compared with well-controlled AF and control patients. Decreased expression of miR-21 was seen in patients with well-controlled AF compared to those with acute new-onset AF and controls (0.6-fold). The miRNA-mRNA interaction demonstrated that SMAD7 and FASLG genes were the targets of miR-21, miR-133b, and miR-499 and were directly related to AF, being involved in apoptosis and fibrosis. Conclusion: The miRNAs had different expression profiles dependent on the AF condition, with higher expression in the acute new-onset AF than well-controlled AF. Clinically, this may contribute to an effective assessment for patients, leading to early detection of AF and monitoring to reduce the risk of other serious cardiovascular events.Artigo Prevalence of the metabolic syndrome according to different criteria in the male population during the Blue November Campaign in Natal, RN, Northeastern Brazil(Diabetes, Metabolic Syndrome And Obesity, 2018) Medeiros, Paulo José de; Espósito, Regina Carmen; Silva, Fernando de Souza; Oliveira, Antonio Gouveia; Aragão, Cícero Flávio Soares; Rocha, Hugo Alexandre Oliveira; Moreira, Sueli Aparecida; Sales, Valéria Soraya de FariasBackground: Metabolic syndrome (MetS) is an aggregation of risk factors associated with increased incidence of cardiovascular disease, type 2 diabetes mellitus, and all-cause mortality. Information on MetS prevalence is scarce in the northeast region, Brazil. This study aims to estimate the prevalence of MetS according to different diagnostic criteria in a community sample of men during the November Blue Campaign living in the metropolitan area of Natal, Rio Grande do Norte, Brazil. Methods: This is a cross-sectional study on 500 men aged 40 years or older invited by the Blue November Campaign of 2015, an awareness program aimed at the prevention of male diseases. The evaluation included blood pressure, anthropometric measurements (weight, height, and waist circumference), fasting blood glucose, and blood lipid profile. The diagnosis of MetS was made according to the criteria of International Diabetes Federation (IDF)/American Heart Association (AHA)/National Heart, Lung, and Blood Institute (NHLBI), IDF, and National Cholesterol Education Program’s Adult Treatment Panel III (NCEP-ATPIII). Results: The prevalence was high by considering the following three criteria: IDF/AHA/NHLBI (66.8%), IDF (60.0%), and NCEP-ATPIII (46.4%). Concordance between diagnostic criteria measured by the kappa statistic (k) was excellent between IDF/AHA/NHLBI and IDF (k=0.85, P<0.0001) and moderate between IDF/AHA/NHLBI and NCEP-ATPIII (k=0.59) and IDF and NCEP-ATPIII (k=0.54). Conclusion: Prevalence of MetS in the male population was high using the three diagnostic criteria. IDF/AHA/NHLBI and IDF criteria have a high level of agreement, but NCEP-ATPIII criteria identify a lower number of MetS cases.Artigo Blue November Campaign as an annual male self-care strategy for healthy aging(Taylor & Francis Group, 2019) Medeiros, Paulo José de; Espósito, Regina Carmen; Dantas Junior, José Hipólito; Oliveira, Antônio Gouveia; Moreira, Sueli Aparecida; Sales, Valéria Soraya de FariasMen ignore self-care, displaying low frequency in health services. Aging increases the prevalence of LUTS and BPE, impacting the quality of life. The objective is to understand how the advancement of age can be determinant for men’s health in Natal, Brazil. Then, 503 men aged between 43 and 83 attended the Blue November Campaign of 2015. All subjects were submitted to anamnesis, clinical and laboratorial evaluation including measuring their blood pressure, waist circumference, glucose, total cholesterol, HDL-C, LDL-C, triglycerides and BMI was calculated. In addition, IPSS, PSA, IIEF-5 and DRE data were collected. The mean IPSS presented an increase with age, 43–59 years (6.28 ± 6.02) and 70–80 years or more (8.65 ± 5.80). PSA dosages increase with aging (adult group 1.63 ± 2.70), being more accentuated in the older group (4.66 ± 5.70), while the mean IIFE-5 showed a decrease with aging in 43–59 years (21.79 ± 4.67) and an important decrease at 70–80 years or more (16.24 ± 6.71). The number of DRE > 30 g showed significant growth in the older group. All presented statistical significance (p < .05) and were associated with aging. The Blue November Campaign creates an annual self-care opportunity for aging men as their health is gradually affected.Artigo Rats offspring exposed to Ipomoea carnea and handling during gestation: neurochemical evaluation(Brazilian Archives of Biology and Technology, 2007-05) Schwarz, Aline; Hosom, Rosana Zoriki; Flório, Jorge Camilo; Bernard, Maria Martha; Górniak, Silvana Lima; Spinosa, Helenice SouzaEstudo anterior realizado em filhotes de ratas tratadas diariamente por gavage com 0,0, 0,7, 3,0 e 15,0 mg/kg de uma solução aquosa obtida de folhas frescas da Ipomoea carnea, do dia 5 ao dia 21 da gestação, mostrou poucas alterações comportamentais na prole em vida adulta. O presente estudo teve como objetivo avaliar a atividade e níveis das monoaminas cerebrais nas proles masculina e feminina expostas ao mesmo tratamento acima descrito. As maiores alterações encontradas, entretanto, foram entre os grupos 0,0 mg/kg e controle negativo (no gavage), impedindo a atribuição das alterações encontradas à solução aquosa. O dados resultantes do grupo controle sugerem que o estresse provocado pela gavage e pelo manuseio das fêmeas enquanto prenhes é suficiente para produzir um importante declínio nos níveis do ácido 3,4 dihidroxifenilacético (DOPAC) e um não menos importante aumento nos níveis do ácido vanilmandélico (VMA), promovendo maior atividade do sistema noradrenérgico (NE).Artigo Avaliação de efeitos toxicológicos e comportamentais da Hypericum perforatum e da Piper methysticum em ratos(Revista Brasileira de Toxicologia, 2009-12) Teixeira, Lilian Tatiana de Araújo; Silveira Júnior, Lenilton Silva da; Queiroz, Fernando Marlisson de; Oliveira, Claudia Nunes de; Schwarz, AlineAs ervas Hypericum perforatum e Piper methysticum são frequentemente empregadas no tratamento de depressões leves a moderadas. O presente trabalho objetivou analisar efeitos tóxicos e alterações comportamentais desses fitoterápicos em ratos. Foram utilizados 17 ratos machos Wistar adultos, separados em três grupos: controle (n=5) e experimentais (n=6/grupo). Os animais experimentais receberam, por gavagem, soluções aquosas de H. perforatum (15 por cento m/v) contendo 2 mg/kg de hipericina, ou de P. methysticum (7,5 por cento m/v) contendo 85,7 mg/kg de kavapironas, diariamente durante 30 dias. Um dia após término do tratamento, os animais tiveram o comportamento avaliado no campo-aberto, no labirinto em cruz elevado e pelo emprego do teste da natação forçada. Em seguida, os animais foram submetidos à eutanásia para a coleta de amostras de sangue e tecidos para estudos bioquímicos e histopatológicos. A análise estatística dos dados indicou que as soluções aquosas empregadas não foram capazes de promover alterações comportamentais nem toxicidade, por não terem sido observadas alterações nos parâmetros ganho de peso, ingestão hídrica, consumo de ração, níveis séricos de ALT, AST, uréia e creatinina, e no estudo histopatológico. Portanto, o presente trabalho sugere que os fitoterápicos, nas dosagens e tempo de administração, empregados não foram capazes de causar toxicidade e alterações comportamentais em ratos.Artigo Análise das mutações C282Y e H63D no gene da proteína HFE em pacientes com hiperferritinemia(Revista Brasileira de Hematologia e Hemoterapia, 2008-02) Leão, Gioconda D. R.A hemocromatose hereditária (HH) é uma doença autossômica recessiva caracterizada pela sobrecarga de ferro em alguns tecidos, como coração, fígado, pâncreas, hipófise e articulações, estando as mutações C282Y e H63D do gene da proteína HFE diretamente relacionadas na etiologia dessa doença. O objetivo deste trabalho foi detectar a freqüência das mutações genéticas H63D e C282Y em um grupo de pacientes com histórico de hiperferritinemia persistente, na cidade de Natal/RN, Brasil. Foram investigados 183 pacientes de ambos os sexos, na faixa etária compreendida entre 15 a 70 anos, nos quais foram investigadas as presenças das mutações C282Y e H63D. Adicionalmente também foram obtidos dados clínicos e informações sobre etilismo e dieta com sobrecarga de ferro desses pacientes. Para realização do estudo genético, inicialmente foram obtidas amostras de DNA genômico a partir de sangue periférico, as quais foram posteriormente submetidas a uma amplificação dos genes C282Y e H63D por meio da reação em cadeia de polimerase utilizado primers específicos. Em seguida, os produtos de amplificação foram submetidos à digestão com as enzimas de restrição Bcl1 e Snab1, possibilitando a detecção das mutações H63D e C282Y respectivamente. Paralelamente também foi investigado um grupo de 60 pessoas sadias, de ambos os sexos, sem hiperferritinemia, visando avaliação da freqüência das mutações H63D e C282Y em nossa região. Dos pacientes investigados, 94 (51,4%) apresentaram ausência de mutação, e 48,6% algum tipo de mutação: 9 casos (5,0%) C282Y heterozigoto mutado, 2 (1,1%) C282Y homozigoto mutado; 56 (31%) H63D heterozigoto mutado, 16 (8,7%) H63D homozigoto mutado e 6 (3,3%) duplo heterozigoto mutado (H63D/C282Y). Embora não tenha sido observada diferença significativa entre os sexos com relação à presença ou não das mutações estudadas tanto no grupo controle como nos pacientes, foi constatada maior concentração de ferritina sérica no sexo masculino. Devido à alta prevalência da HH em nossa região, o diagnóstico molecular precoce da HH torna-se indicado, principalmente em portadores de hiperferritinemia, em virtude da eficácia e baixo custo do tratamento, evitando com isso o surgimento das manifestações clínicas, aumentando também a qualidade e a expectativa de vida desses pacientes.Artigo Caracterização e correlação do fenômeno pró-zona com títulos de sororeatividade do VDRL e reação de imunofluorescência indireta em soros de pacientes com sífilis(Revista Brasileira de Análises Clínicas, 2006) Azevedo, Luciana Karla Araújo de; Fernandes, Paulo Sergio Gomes; Silva, Dany Geraldo Kramer Cavalcant e; Batista Neto, Manoel Josué; Queiroz, Maria Gorete Lins de; Dantas, Valéria Cristina Ribeiro; Sales, Valéria Soraya de Farias; Cavalcanti Júnior, Geraldo BarrosoIntrodução: Treponema pallidun é o agente etiológico da sífilis uma doença sexualmente transmissível. No imunodiagnóstico dessa doença utilizam-se dois diferentes tipos de testes sorológicos. Inicialmente, as amostras são triadas qualitativamente e quantitativamente por um teste não treponêmico como o veneral disease research laboratory (VDRL) e, em seguida, os soros reagentes são testados para a detecção de anticorpos específicos para o Treponema pallidum, como a reação de imunofluorescência indireta através do fluorescent treponemal antibody absorption assay (FTA-ABS). Objetivos e Metodologia: Avaliar através do VDRL quantitativo e qualitativo a sororeatividade de 40 pacientes com sífilis e comparar com a presença do fenômeno pro-zona e resultados obtidos pelo FTA-ABS. Resultados e Discussão: Os níveis de reatividade das amostras testadas pelo VDRL variaram de 1:2 a 1:256. O fenômeno pró-zona foi observado em 8/40 soros (20%) se correlacionando com altos títulos de reatividade na maioria dos casos. O FTAABS foi reagente em 39/40 amostras (97,5%) apresentando forte e moderada reatividade independente dos títulos obtidos pelo VDRL e a presença ou ausência do fenômeno pró-zona na maioria dos casos, demonstrando uma maior sensibilidade desse exame quando comparado com o VDRL. Conclusão: Nossos resultados mostraram a importância da realização do VDRL quantitativo e qualitativo na investigação seguida pelo FTA-ABS na investigação sorológica da sífilis.Artigo Avaliação da poluição sonora no centro comercial de Santa Cruz, Rio Grande do Norte(Engenharia Ambiental: Pesquisa e Tecnologia, 2010) Cavalcante, Ananília R. S.; Araújo, Camila M. M. de; Silva, Cláudio R. A. da; Morais, Hugo G. A. de; Melo, Leana da Silva; Passos, João Octávio S.; Guedes, Dimitri T.; Lima, Jucimar F. V.; Calvalcanti Júnior, Geraldo B.; Silva, Marizaldo L.; Silva, Dany G. K. Cavalcanti eAs cidades modernas se caracterizam, em sua maioria, pela concentração excessiva de comércio e serviço nas áreas centrais, fato que contribui para diversos problemas, entre eles a poluição acústica, que acarretando em inconvenientes e problemas de saúde à população. O presente estudo objetivou analisar a poluição sonora no centro comercial da cidade de Santa Cruz / RN. Foram analisados 15 pontos nas principais ruas da cidade, no período verpertino e matutino, por duas semanas, com o analisador de ambiente Multi-Funções Modelo THDL – 400, com intevalos de 40 minutos entre as medições. Observou-se que a maioria dos pontos apresentavam níveis de ruídos acima dos 70 decíbeis no período analisado. Portanto, acima dos 65dB, propostos nas legislações, sendo necessário intensificação dos processos de fiscalização e educação ambiental.Artigo Coexpression of p53 protein and MDR functional phenotype in leukemias: the predominant association in chronic myeloid leukemia(Wiley, 2004) Cavalcanti Junior, Geraldo Barroso; Vasconcelos, Flavia da Cunha; Faria, Giselle Pinto de; Scheiner, Marcos Antônio Maurício; Dobbin, Jane de Almeida; Klumb, Claudete Esteves; Maia, Raquel C.; https://orcid.org/0000-0001-9227-4145Background: One of the best characterized resistance mechanisms of leukemias is multidrug resistance (MDR) mediated by P-glycoprotein (Pgp) and multidrug-resistant related protein (MRP). In addition to Pgp and MRP, p53 mutation or inactivation might play a relevant role in therapeutic failure. Some studies have demonstrated that Pgp and MRP may be activated in association with overexpression of mutant or inactivated p53 protein. The aim of this study was to investigate the association between p53 expression and MDR functional phenotype analyzed by flow cytometry (FCM). Methods: Rhodamine-123 assay analyzed by FCM was used to detect the MDR phenotype that was positive in 18 out of 41 (43.9%) cases of chronic myeloid leukemia (CML), 16 out of 28 (57.1%) chronic lymphoid leukemia (CLL) cases, 11 out of 28 (39.3%) acute myeloid leukemia (AML) cases, and four out of 22 (18.2%) acute lymphoid leukemia (ALL) cases. Results: Variable levels of p53 expression were observed in leukemic cells: 12 out of 41 (29.2%) in CML, nine out of 28 (32.1%) in CLL, 15 out of 28 (53.6%) in AML, and eight out of 22 (36.4%) in ALL samples. Conclusions: In our study, no significant association between p53 expression and MDR functional phenotype was observed in ALL, CLL, and AML. On the other hand, a significant association (P 0.0003) of the coexpression was observed in CML. The p53 overexpression was more frequently seen in the accelerated phase and the blastic phase of this disease. Our results suggest that an MDR functional phenotype could be associated with p53 mutation in the advanced stage of leukemias.Artigo Estudo preliminar in vitro da atividade antiacetilcolinesterásica de extratos etanólicos de plantas: possíveis alternativas no tratamento da doença de alzheimer(2011) Queiroz, Fernando Márlisson de; Nascimento, Maria Aparecida do; Schwarz, AlineA inibição da acetilcolinesterase (AChE), a enzima que inativa a acetilcolina, é atualmente a principal estratégia terapêutica sintomática da Doença de Alzheimer. Vários constituintes de plantas demonstraram ser inibidores da AChE. Extratos brutos etanólicos moles de Solanum tuberosum, Heteropterys aphrodisiaca, Croton urucurana, Chenopodium ambrosioides e Cereus Jamacaru, foram submetidos à investigação da atividade de inibição da AChE eritrocitária. Todos os extratos, exceto o de raíz de H. aphrodisiaca, demonstraram inibir a AChE em concentrações entre 0,625mg/ml e 0,5mg/ml, sendo mais relevante a atividade inibitória dos extratos de raíz de S. tuberosum, empregado nesse estudo como controle positivo, e do caule de C. urucurana, uma das espécies de plantas investigadas nesse estudo. Entretanto devem ser feitos estudos in vivo para certificar essa atividade, inclusive se ocorre na AChE cerebral.Artigo Chromosome 17 abnormalities and mutation of the TP53 gene: Correlation between cytogenetics, flow cytometry and molecular analysis in three cases of chronic myeloid leukemia(Sociedade Brasileira de Genética, 2005) Otero, Luize; Cavalcanti Júnior, Geraldo Barroso; Klumb, Claudete Esteves; Scheiner, Marcos Antonio Mauricio; Magluta, Eliane Pereira Simões; Fernandez, Teresa de Souza; Silva, Maria Luiza Macedo; Pires, Virgínia; Andrade, Gabriela Vasconcelos; Maia, Raquel Ciuvalschi; Tabak, DanielAlterations involving the short arm of chromosome 17 (17p) during the progression of chronic myeloid leukemia (CML) have been described. This chromosomal region contains the tumor suppressor gene TP53 that may be an important factor in the evolution of this disease. In this study, we used flow cytometry and western blotting to assess p53 protein expression and single stranded conformational polymorphism to examine TP53 gene alterations in three patients with CML who showed alterations in 17p. Only the case with del(17)(p11) had p53 expression positive by flow cytometry and an abnormal migration pattern by SSCP analysis. The importance of the correlation between the results obtained with these techniques, as well as the clinical course of the patients, are discussed.Artigo Antioxidant activity and protective effect of Turnera ulmifolia Linn. var. elegans against carbon tetrachloride-induced oxidative damage in rats(Elsevier, 2012-12) Brito, Naira J.N.; López, Jorge A.; Nascimento, Maria Aparecida do; Macêdo, José B.M.; Silva, Gabriel Araujo; Oliveira, Cláudia N.; Rezende, Adriana Augusto de; Brandão-Neto, José; Schwarz, Aline; Almeida, Maria das GraçasThe present study aimed to determine whether the leaves of Turnera ulmifolia Linn. var. elegans extract exert significant antioxidant activity. The antioxidant activity of its hydroethanolic extract (HEETU) was evaluated by assessing (a) its radical scavenging ability in vitro, and (b) its in vivo effect on lipid peroxidation and antioxidant enzyme activities. The in vitro antioxidant assay (DPPH) clearly supported HEETU free radical scavenging potential. Moreover, glutathione content and antioxidant enzyme activities (glutathione peroxidase, superoxide dismutase and catalase) were significantly enhanced in CCl4- treated rats due to oral HEETU-treatment (500 mg/kg b.w.) over 7 and 21 days. In addition, an improvement was observed in lipid peroxidation and serum biochemical parameters (aspartate aminotransferase and alanine aminotransferase), indicating a protective effect against CCl4-induced liver injuries, confirmed by histopathological studies. The HEETU effect was comparable to the standard drug Legalon (50 mg/kg b.w.) under the same experimental condition. Quantitative analysis of the HPLC extract revealed the presence of flavonoids, wich mediate the effects of antioxidant and oxidative stress. In conclusion, extract components exhibit antioxidant and hepatoprotective activities in vitro and in vivo.Artigo The impact of body mass on inflammatory markers and insulin resistance in polycystic ovary syndrome(Taylor and Francis, 2015-11-06) Santos, Ana Celly Souza dos; Soares, Nayara Pereira; Costa, Eduardo Caldas; Sá, Joceline Cássia Ferrezini de; Azevedo, George Dantas de; Lemos, Telma Maria Araújo MouraObjective: to evaluate inflammatory markers and insulin resistance (IR) in women with and without polycystic ovary syndrome (PCOS), with different body mass index (BMI). Methods: tumor necrosis factor-alpha (TNF-a), interleukin-6 (IL-6) and C-reactive protein (CRP) were assessed in serum samples from 40 women in reproductive age. Patients were divided into four groups: I (non-eutrophic with PCOS, n¼12), II (non-eutrophic without PCOS, n¼10), III (eutrophic with PCOS, n¼8) and IV (eutrophic without PCOS, n¼10) being non-eutrophic, the overweight and obese women with BMI425 kg/m2 and eutrophic women with BMI524.9 kg/m2. Homeostatic model assessment (HOMA-IR) was calculated for evaluation of IR. Results: PCOS patients showed increased levels of CRP (p50.01) and HOMA-IR (p50.01). When divided by BMI, both non-eutrophic and eutrophic PCOS showed increased CRP levels (p50.01) and HOMA-IR (p50.01). There were no differences in TNF-a and IL-6 levels between groups. Conclusion: in the PCOS group, the levels of CRP and IR were elevated, compared to their counterparts, regardless of body massArtigo Affect-regulated exercise: an alternative approach for lifestyle modification in overweight/obese women with polycystic ovary syndrome(Taylor and Francis, 2015-09-25) Costa, Eduardo Caldas; Sá, Joceline Cássia Ferezini de; Costa, Ingrid Bezerra Barbosa; Meireles, Rodrigo da Silva Rosa Veleda; Lemos, Telma Maria Araújo Moura; Elsangedy, Hassan Mohamed; Krinski, Kleverton; Azevedo, George Dantas deObjective: affect-regulated exercise (‘‘ARE’’) is an alternative approach to guide exercise intensity based on feeling of pleasure. The aim of this study was to analyze if overweight/obese women with polycystic ovary syndrome (PCOS) meet the American College of Sports Medicine (ACSM) recommendation regarding to exercise intensity to improve health status during a single bout of ‘‘ARE". Methods: a sample of 14 overweight/obese women with PCOS (18–34 years) performed a single bout of ‘‘ARE’’ (40 min of aerobic exercise on outdoor track). The Feeling Scale (FS) was used to guide ‘‘ARE’’ intensity/pace maintaining an affective valence between ‘‘good’’ and ‘‘very good’’ during all time. Heart rate (HR), speed, % of HR at first and second ventilatory threshold (VT1 and VT2) and time spent at moderate (64–76% of HRmax) and vigorous (77–95% of HRmax) intensity during ‘‘ARE’’ were measured with a global positioning system (GPS) device. Results: volunteers exercised at 73% (68–78%) of HRmax, 5.8 (5.2–6.2) km/h, 93.4% of HR at VT1 (89.3–98.2) and 80.5% of HR at VT2 (75.3–84.6) and spent 480% of time at moderate intensity. Conclusions: overweight/obese women with PCOS met the ACSM recommendation regarding exercise intensity to improve health status when exercised between ‘‘good’’ and ‘‘very good’’ of FS. Thus, ‘‘ARE’’ may be an interesting approach to be used in clinical practice regarding to exercise prescription and/or physical activity adviceArtigo Polycystic Ovary Syndrome: aggressive or protective factor for the retina? Evaluation of macular thickness and retinal nerve fiber layers using high-definition optical coherence tomography(Hindawi, 2015-02-11) Souza Júnior, José Edvan de; Garcia, Carlos Alexandre de Amorim; Soares, Elvira Maria Mafaldo; Maranhão, Técia Maria Oliveira; Lemos, Telma Maria Araujo Moura; Azevedo, George Dantas deObjective. To compare macular thickness (MT) and retinal nerve fiber layers (RNFL) between women with polycystic ovary syndrome (PCOS) and healthy women. Materials and Methods. The study included 45 women with PCOS and 47 ovulatory women undergoing clinical-gynecological and ophthalmic evaluations, including measurement of MT, RNFL, and optic disc parameters using optical coherence tomography. Results. The superior RNFL around the optic nerve was significantly thicker in PCOS than in healthy volunteers (𝑃 = 0.036). After stratification according to insulin resistance, the temporal inner macula (TIM), the inferior inner macula (IIM), the nasal inner macula (NIM), and the nasal outer macula (NOM) were significantly thicker in PCOS group than in control group (𝑃 < 0.05). Both the presence of obesity associated with insulin resistance (𝑃 = 0.037) and glucose intolerance (𝑃 = 0.001) were associated with significant increase in the PC1 mean score, relative to MT. A significant increase in the PC2 mean score occurred when considering the presence of metabolic syndrome (𝑃 < 0.0001). There was a significant interaction between obesity and inflammation in a decreasing mean PC2 score relative to macular RNFL thickness (𝑃 = 0.034). Conclusion. Decreased macular RNFL thickness and increased total MT are associated with metabolic abnormalities, while increased RNFL thickness around the optic nerve is associated with hormonal changes inherent in PCOSArtigo Diet-Induced weight loss reduces DNA damage and cardiometabolic risk factors in overweight/obese women with polycystic ovary syndrome(Karger Publishers, 2016-04-14) Soares, Nayara Pereira; Santos, Ana Celly Souza dos; Costa, Eduardo Caldas; Azevedo, George Dantas de; Damasceno, Débora Cristina; Fayh, Ana Paula Trussardi; Lemos, Telma Maria Araujo MouraAims: we aimed to investigate the impact of following a diet to induce weight loss (500 kcal deficit per day) over DNA damage and cardiometabolic risk factors in women with overweight/obesity diagnosed with polycystic ovary syndrome (PCOS). Methods: a study was conducted in Natal, RN, Brazil selecting overweight/obese (body mass index ≥25 and <39 kg/m2) women (18-35 years). The levels of DNA damage were assessed by a single cell gel electrophoresis. Repeated 24 h dietary recall questionnaires, anthropometry, biochemical profile and sex hormones were collected at baseline and after 12 weeks of intervention. Results: Women exhibiting a decrease in the markers of DNA damage: tail intensity (24.35 ± 5.86 - pre diet vs. 17.15 ± 5.04 - post-diet; p < 0.001) and tail moment (20.47 ± 7.85 - pre diet vs. 14.13 ± 6.29 - post-diet; p < 0.002). Reduction of calorie intake, weight loss, decreased sexual hormone and cardiometabolic markers such as insulin, homeostasis model assessment of insulin resistance and low-density lipoprotein cholesterol were verified In the multivariate regression analysis, quantitative insulin sensitivity check index and progesterone were responsible for the variation markers in DNA damage before the diet, losing its influence upon diet. Conclusion: DNA damage and the impact of cardiometabolic risk factors decreased after the intervention in women with PCOS, indicating the relevance of a nutritional approach in this group of patientsArtigo Revisiting an unsolved problem – impact of SLICC criteria on the risk of metabolic syndrome(SAGE Publications, 2016-07-11) Lima Júnior, J. C.; Lemos, Telma Maria Araujo Moura; Azevedo, George Dantas de; Vilar, Maria José PereiraAs with mostprevious studies on the prevalence of metabolicsyndrome (MetS) in systemic lupus erythematosus(SLE), in which the prevalence varies greatly, itwas found to be always greater than in non-lupus patients. MetS, a bundle of cardiovascular risk factors, is highly prevalent and associated with increased rate of cardiovascular events and death. Apart from these risk factors, MetS is closely correlated with inflammation. Not only are they related to each other, but the inflammatory burst also precedes the MetS. Was evaluated the influence of SLICC criteria and other disease-specific factors in the presentation of MetS. In order to evaluate these factors, It was conducted a cross-sectional pilot study with 59 women with SLE according to the American College Rheumatology (ACR) criteria at the rheumatology out patient clinic. Individuals with SLE had a higher prevalence of MetS (30.5%) than controls (20.5%), as shown previously. Despite this higher prevalence, there was no si-nificant association between the presence of SLE and whether individuals had MetS or not(p¼0.117). Via a binary logistic regression, was evaluated the chance of specific factors associated with SLE predicting the presence of MetS. No significant association was detected between MetS and any SLE specific factors.Artigo Aerobic exercise improves cardiac autonomic modulation in women with polycystic ovary syndrome(Elsevier, 2016-01) Sá, Joceline Cassia Ferezini de; Costa, Eduardo Caldas; Silva, Ester da; Tamburús, Nayara Y.; Porta, Alberto; Medeiros, Leany F.; Lemos, Telma Maria Araujo Moura Lemos; Soares, Elvira M. M.; Azevedo, George Dantas deBackground: this study aimed to evaluate the effects of aerobic exercise on cardiac autonomic modulation in women with polycystic ovary syndrome (PCOS). Methods: thirty women with PCOS (25.8 ± 4.8 years old; body mass index, BMI ≥ 25 kg/m2) were divided into two groups; exercise group (n = 15) and control group (n = 15). R–R interval was recorded during 15-min at rest in the supine position. Heart rate variability (HRV) was analyzed by linear (rMSSD, SDNN, LF, HF, LFnu, HFnu, and LF/HF) and nonlinear methods (Shannon entropy, SE; symbolic analyses, 0 V%, 1 V%, 2LV%, and 2UV%) at baseline and after 16 weeks. The multivariate analysis of covariance was used to analyze the effects of exercise on HRV indexes, adjusted for changes in BMI, fasting insulin, and testosterone level. Results: the exercise group increased parasympathetic modulation (rMSSD, HF, HFnu, 2UV%; (p b 0.05)) and decreased sympathetic modulation (LF, LFnu, 0 V%; (p b 0.05)) independently of changes in BMI, fasting insulin, and testosterone level. Moreover, the exercise group decreased resting HR and systolic blood pressure (p b 0.05). All parameters remained unchanged in the control group. Conclusions: aerobic exercise increased vagal modulation and decreased sympathetic modulation in women with PCOS. This finding reinforces the recommendations for exercise during the clinical management of these patients
