Efeito do tratamento por plasma na proliferação de fibroblastos e esterilização de membranas de quitosana

Chitosan is being studied for use as dressing due their biological properties. Aiming to expand the use in biomedical applications, chitosan membranes were modified by plasma using the following gases: nitrogen (N2), methane (CH4), argon (Ar), oxygen (O2) and hydrogen (H2). The samples were characterized by scanning electron microscopy (SEM), atomic force microscopy (AFM), contact angle, surface energy and water absorption test. Biological Tests were also performed, such as: test sterilization and proliferation of fibroblasts (3T3 line). Through SEM we observed morphological changes occurring during the plasma treatment, the formation of micro and nano-sized valleys. MFA was used to analyze different roughness parameters (Ra, Rp, Rz) and surface topography. It was found that the treated samples had an increase in surface roughness and sharp peaks. Methane plasma treatment decreased the hydrophilicity of the membranes and also the rate of water absorption, while the other treatments turned the membranes hydrophilic. The sterilization was effective in all treatment times with the following gases: Ar, N2 and H2. With respect to proliferation, all treatments showed an improvement in cell proliferation increased in a range 150% to 250% compared to untreated membrane. The highlights were the treatments with Ar 60 min, O2 60 min, CH4 15 min. Observing the results of the analyzes performed in this study, it appears that there is no single parameter that influences cell proliferation, but rather a set of ideal conditions that favor cell proliferation

Prevalência e fatores associados da síndrome de Osgood-Schlatter em uma amostra populacional de adolescentes brasileiros

Osgood-Schlatter (O-S) syndrome, a pathology of the musculoskeletal system, exhibits high incidence in adolescence, a phase of accelerated bone growth. Detection of physiopathological mechanisms that may cause disorders and dysfunctions in bone growth must be taken into account when planning physical activities, in order to promote normal physiological growth patterns. The aim of this epidemiological investigation was to identify and analyze the relationships between sociodemographic, anthropometric and clinical aspects and O-S. A cross-sectional design was used, with a representative sample of 956 subjects: 474 (49.6%) males and 482 (50.4%) females. Age range varied between 12 and 15 years (mean = 13.7±1.04). We used a battery of tests, previously applied in a pilot study, which met the aims of the investigation. Descriptive statistics (frequency, mean and standard deviation) were used and the odds ratio was calculated from bivariate and multivariate logistic regression (p<0.05). A prevalence of 9.8% was found (n = 94 cases): 11% males and 8.3% females. Hierarchized multivariate analysis showed a significant association between regular physical activities (OR= 1.94; CI 95%, 1.22-3.10) and shortening of the rectus femoris muscle (OR= 7.15; CI 95%, 2.86-17.86). The results may serve as a basis for therapeutic and prophylactic measures, in addition to increasing our knowledge of this syndrome in Brazilian adolescents. This investigation used a multidisciplinary approach, involving elements of anatomy, nutrition, physical education and physical therapy to elucidate the object under study related to Osgood-Schlatter syndrome

Atividade física e outros fatores associados à função sexual em mulheres de meia idade

Este estudo teve por objetivo avaliar os fatores associados à disfunção sexual em mulheres de meia idade. Realizou-se um estudo descritivo transversal, que compreendeu 370 mulheres, entre 40 a 65 anos, atendidas nas Unidades Básicas de Saúde de cada distrito sanitário (Norte, Sul, Leste e Oeste) da cidade de Natal, no estado do Rio Grande do Norte, Brasil. Para avaliar a função sexual utilizou-se o Female Sexual Function Index (FSFI). A sintomatologia climatérica foi avaliada por meio do Menopause Rating Scale (MRS). O Índice de Blatt-Kupperman (IMBK) foi utilizado para avaliação quantitativa global da ocorrência de sintomas/queixas. A atividade física foi avaliada pelo questionário International Physical Activity Questionnaire - IPAQ (versão curta). A avaliação da qualidade de vida geral se deu pelo WHOQOL-Bref. A análise estatística foi realizada utilizando o programa estatístico MINITAB version16. Além de análises descritivas das variáveis categorizadas, utilizou-se o teste qui-quadrado de Person com o intuito de verificar possíveis associações entre as variáveis sociodemográficas, comportamentais, clínicas, níveis de atividade física, sintomatologia climatérica, qualidade de vida e a função sexual das mulheres estudadas. Desenvolveu-se a regressão logística para verificar a influência dessas variáveis sobre a disfunção sexual. Considerou-se o nível de significância de 5% para todos os testes. Os resultados mostraram que a média de idade das mulheres estudadas foi de 49,8 (±8,1) anos. Do total dessas mulheres, 67% apresentaram disfunção sexual. Observou-se que 54,5% delas se encontravam na pré-menopausa. Avaliando a influência das variáveis sobre a função sexual; faixa etária (56-65) (p<0,001), estado civil (divorciada/separada) (p < 0,001), escolaridade (baixa) (p=0,017), menopausa (p < 0,001), histerectomia (p = 0,016), nível de atividade física (sedentária) (p=0,002), sintomas do climatério (forte) (p<0,001) e qualidade de vida (baixa) (p<0,001), estiveram associados à disfunção sexual em mulheres de meia idade. Concluiu-se neste estudo que fatores sociodemográficos, clínicos, comportamentais, níveis de atividade física, sintomatologia climatérica e qualidade de vida influenciam significativamente a função sexual na mulher de meia idade

Níveis pressóricos elevados em mulheres com síndrome dos ovários policísticos: prevalência e fatores de risco associados

investiga a prevalência de níveis pressóricos elevados e avaliar a correlação entre níveis de pressão arterial (PA) e outros fatores de risco cardiovascular em pacientes com síndrome dos ovários policísticos (SOP).Por meio de estudo transversal foram comparados os níveis de PA e parâmetros antropométricos e bioquímicos de risco cardiovascular em 113 mulheres com SOP (idade 26,2±4,3 anos) e num grupo controle constituído por 242 mulheres saudáveis da população geral (26,8±5,0 anos). o grupo SOP apresentou prevalência de PA alterada (≥130/85 mmHg) significativamente superior ao grupo controle (18,6% vs. 9,9%, respectivamente; p<0,05). Mulheres com SOP apresentaram valores médios superiores de PA sistólica, índice de massa corporal (IMC), circunferência da cintura (CC), triglicerídeos e glicemia de jejum, além de níveis inferiores de HDL - colesterol, em comparação ao grupo controle (p<0,01). No grupo SOP, os valores de PA sistólica e diastólica apresentaram correlação positiva significativa com a idade, IMC, CC e triglicerídeos (p<0,05). A freqüência de mulheres com valores de PA acima do limite da normalidade foi significativamente maior no grupo SOP, em relação ao grupo controle. Adicionalmente, os valores de PA se correlacionaram positivamente com outros fatores de risco cardiovascular como obesidade e níveis de triglicerídeos. Esses achados alertam para a relevância de estratégias preventivas em mulheres com SOP, no sentido de evitar eventos mórbidos relacionados ao sistema cardiovascular

Prevalência e fatores associados à sintomatologia dolorosa e a qualidade de vida de odontólogos da cidade de Teresina-PI

Objective: Identify the factors associated to the painful symptomatology and the quality of life and in dentists in the city of Teresina-PI. Brazil. Methods It was accomplished a cross-sectional study with 175 dentists registered with the Regional Council of Dentistry-PI from March to May, 2007. For characterization of the dentists we used a multidimensional questionnaire containing sociodemographic (age, sex) and professional information (time of service, journey to work). The evaluation of the presence of pain was performed by the Protocol of Painful Symptoms of McGILL. The WHOQOL-Bref was used to assess quality of life through physical, psychological, social and environmental domains. Results / Conclusions The painful symptomatology was reported in 69,7% of individuals, being observed in 77.3% of women and 60.3% of men. Body regions where pain was prevalent was the regions of neck (69,2%) lower back (69,7%). The dentists had high levels of self-perception of quality of life satisfaction and health. 96,0% of the individuals reported quality of life as very good, and only 16.6% reported dissatisfied with health. The Physical and Environmental domains showed values higher than the psychological and social domains. The painful symptomatology of studied dentists is associated with female sex (RP=1.28; IC95% 1.04-1.58; p<0.01). A multivariate analysis by logistic regression was performed and only the painful symptoms (OR = 2.51, IC95% 1,21-5,21) remained associated with the quality of life of these professionals when adjusted for other variables studied

Síndrome metabólica e fatores associados: estudo comparativo com mulheres que apresentaram pré-eclâmpsia e gravidez normal, acompanhadas cinco anos após o parto

Preeclampsia is defined as an extremely serious complication of the pregnancy-puerperium cycle with delayed emergence of cardiovascular risk factors, including metabolic syndrome. The research aimed estimate the prevalences of metabolic syndrome and associated factors in women with preeclampsia and normal pregnancy followed five years after childbirth. This is a cross-sectional observational study using a quantitative approach, conducted at a maternity school in the city of Natal in Rio Grande do Norte state. The sample was composed of 70 women with previous preeclampsia and 75 normal selected by simple random probability sampling. Subjects were analyzed for sociodemographic, obstetric, clinical, anthropometric and biochemical parameters. International Diabetes Federation criteria were adopted to diagnose metabol ic syndrome. The Kolmogorov-Smirnov, Mann-Whitney, Student s t, Pearson s chi-squared, and Fisher s exact tests, in addition to simple logistic regression, were used for data analysis, at a 5% significance level (p ≤ 0.05). Statistical tests demonstrated elevated body mass index (p = 0.001), predominance of family history of diabetes mellitus (p = 0.022) and significantly higher prevalence of metabolic syndrome in the preeclampsia group (37.1%) when compared to normal (22.7%) (p = 0.042). Intergroup comparison showed a high number of metabolic syndrome components in women with previous preeclampsia. Altered systolic and diastolic blood pressure (p < 0.001) was the most prevalent, followed by low concentrations of high-density lipoproteins (p = 0.049), and hyperglycemia (p=0.030). There was a predominance of the metabolic syndrome in women with schooling 0-9 years (42.4%) (p = 0.005), body mass index above 30Kg.m 2 (52.3%) (p < 0.001), uric acid high (62.5%) (p = 0.050 and family history of hypertension (38.5%) (p< 0.001). Multivariate analysis of the data showed that the body mass index above 30 kg.m2, education level less than 10 years of study (p < 0.001) and family history of hypertension (p = 0.002) remained associated with the metabolic syndrome after multivariate analysis of the data. It is considered Women with previous preeclampsia exhibited high prevalence of metabolic syndrome and their individual components in relation to normal, especially, altered systolic and diastolic blood pressure, low concentrations of high-density lipoproteins and hyperglycemia. The factors associated to this ou tcome were obesity, less than 10 years of schooling, and family history of hypertension. Overall, this study identified young women with a history of PE exposed to a higher cardiovascular risk than normal

Fatores associados à mortalidade dos idosos com as condições de vida da população do Nordeste do Brasil

As condições de vida são usualmente entendidas como importantes fatores intervenientes das causas básicas de mortalidade e da qualidade de vida da população. Ao considerar esta questão em uma população idosa e sua influência nas causas mais relevantes que as levam à morte, teve-se como objetivo principal, estudar a associação da mortalidade dos idosos por doenças cardiovasculares para ambos os sexos, com indicadores que expressam as condições de vida da população do Nordeste, nos anos 2000 e 2010. Para atingir tal propósito foi traçado um desenho de estudo ecológico com cortes transversais nos anos 2000 e 2010 tendo como unidades de análises as microrregiões e a mesorregiões do Nordeste. Utilizou-se a Modelagem de Equações Estruturais (MEE) para explicar essas associações, tomando como base as estatísticas de óbitos por doenças cardiovasculares (construto endógeno) e variáveis socioeconômicas e demográficas (construto exógeno) das microrregiões do Nordeste, para o ano 2000. Utilizou-se o Método dos Componentes Principais como recurso metodológico na construção de um índice sintético que permitiu classificar as condições de vida nas mesorregiões do Nordeste, tomadas como unidades de análises, nos anos 2000 e 2010, de acordo com as condições de vida e as principais causas de mortalidade por doenças cardiovasculares. A aplicação da MEE sugeriu uma forte associação do construto exógeno condições de vida, composto pelos indicadores: anos de estudo dos homens idosos, percentual de idosos em domicílios com banheiro/água encanada e probabilidade de sobrevivência aos 60 anos, com a variável desfecho taxa de mortalidade por doenças cardiovasculares dos homens e mulheres idosos. O índice sintético construído permitiu identificar os diferentes ritmos de envelhecimento populacional entre as regiões e distintos processos de evolução dos níveis de mortalidade pelas doenças cardiovasculares, muitas delas compatíveis com as condições de vida no Nordeste. Os resultados sugerem que o construto condições de vida está fortemente associado por esta causa de morte entre os idosos para ambos os sexos no Nordeste do Brasil. Neste sentido, sugere-se que estes resultados sejam considerados como relevantes para formulação de políticas de saúde regionais voltadas para este contingente populacional do Nordeste do Brasil

Prevalência e fatores associados à dor em professores de educação física em academias de ginástica da cidade do Salvador-BA

Physical Education professionals are usually exposed to excessive physical workloads that evolve into painful symptomatology and muscle and bone disorders that originate from the work-related exercises. Purposo: The goal of this study was to investigate the prevalence and factors associated with pain painful symptomatology in teachers in gymnastics academies. An analytical transversal cut study was performed involving 163 gymnastics teachers working in the main gyms in the city of Salvador-BA. For evaluation of pain, validated versions in Portuguese of the McGill Protocol and the Wisconsin Pain Inventory were used. For obtain results of descriptive statistical analysis of the collected data was performed, followed by TStudent, and Pearson and Spearman correlation tests to verify possible correlations between the presence of pain and other variables which were considered independent. Finally, for the identification of potential risk factors associated with pain, a binary logistic regression analysis was performed. For all statistical analysis, we cnsidered p< 0.05. Results: The painful symptoms was reported by 88.3% of the subjects surveyed. High pain levels were observed in 63.8% of the interviewed professionals, where the intensity varied from moderate to severe. Pain in the lumbar region was present in 55.2% of subjects. Positive correlations were found between the level of pain intensity and the variables related with the workload activity and daily life of the teachers in almost all body joints analyzed. Some factors had been verified associates to the painful sintomatologia as the age of the professionals, the daily hours load of labor work, and the lack of interval of rest between the lessons. Conclusions: We found a high prevalence in gym teachers working in the city of Salvador-BA, which interfered in various daily activities of their home and professional lives. The most affected region was the lumbar region, followed by the knees, neck, shoulders, ankles, hands, hips, feet, elbows and forearms. The factors associated with development of painful symptomatology were the age of the professionals, daily hours of work and the lack of rest intervals between lessons. The high prevalence of pain in Physical Education teachers can be regarded as a serious occupational health problem, which would demand the urgent deployment of preventive intervention programs to minimize the impact of pain among these professionals

Estudo dos fatores associados à infecção chagásica em área endêmica do Rio Grande do Norte

The Chagas disease is a infectious and parasite disease that has as the causative agent a Trypanosoma cruzi, a protozoan parasite that can be transmitted to humans by the faeces of triatomines ( barbeiros ) in the blood-sucking. To understand the relationship between factors associated with chagasic infection and the risk of transmission of Trypanosoma cruzi, this work aimed to make a correlation between the results of serology, obtained by different immunological techniques, used for diagnosis of Chagas disease and risk factors to which the population of the city of Apodi-RN is exposed, to be considered a endemic area. The case-control study was conducted with 199 individuals, which initially was applied a questionary about socio-economic questions and some risk factors which they were exposed and also favor the spread of disease. Then was given the diagnosis by immunological techniques of serology by indirect hemagglutination, ELISA and indirect immunofluorescence. From the diagnosis, the subjects were divided into case group (presence of infection) and control group (no infection). Regarding the descriptive characteristics of the sample, were found a higher frequency of female individuals (59.3%), between 36 and 50 years of age (36.7%), with low education level (91%) and income monthly up to 1 minimum wage (67.8%). The serology, performed by three techniques of different principles, had a reactivity of 38.9% by Indirect Hemagglutination, 39.7% by ELISA and 38.7% by Indirect Immunofluorescence. As the result of the serology, 71 of samples showed reactivity in 2 or more techniques. On some risk variables, was found a significant relationship between individuals who had been bitten by the triatomines and had positive serology for Chagas disease (93.3%). Other variables of risk revealed individuals who had positive serology and had domestic animal (80.3%), lived in poorly maintained homes (97.2%) and near the forest (84.5%). A better understanding of the dynamics of transmission of T. cruzi and the risk factors that contribute to its occurrence in a region are needed to develop effective strategies for control of Chagas disease in these áreas

Estudo dos genes do complexo do antígeno leucocitário humano (hla) associados à susceptibilidade ao diabetes mellitus tipo 1

Of all of the genes associated with the development of Diabetes mellitus type 1 (T1D), the largest contribution comes from the genes in the Human Leukocyte Antigen (HLA) region, mostly the class II DR e DQ genes. Specific combinations of alleles DRB1, DQA1 and DQB1 constituting haplotypes, and further, a combination of more than one haplotype, providing multilocus genotypes are associated with susceptibility, protection and neutrality to DM1. Thus, the aim of present study was to verified the association of polymorphisms of HLA genes class II with susceptibility to type 1 diabetes mellitus (T1D). Ninety-two patients with T1D and 100 individuals normoglycemics (NG) aged between 6 and 20 years were studied. Genomic DNA was obtained from peripheral whole blood, collected in EDTA tube, using the extraction kit Illustra Triple Prep®, GE Healthcare. For HLA typing was used DNA LABType system by One Lambda kit applying Luminex® technology to the method of PCRSSO typing reverse. The alleles DRB1*03:01, *04:05, *04:01, *04:02, DQA1*03:01g, *05:01g, DQB1*02:01g, *03:02, the haplotypes DRB1*03:01-DQA1*05:01-DQB1*02:01, DRB1*04:05-DQA1*03:01g-DQB1*03:02, DRB1*04:02-DQA1*03:01g-DQB1*03:02, DRB1*04:01-DQA1*03:01g-DQB1*03:02 and DR3-DQ2/DR4-DQ8 genotype were significantly associated with the chance of developing T1D. The alleles DRB1*11:01, *15:03, *15:01, *13:01, DQA1*01:02, *04:01g, *01:03, DQB1*06:02, *03:01g, *06:03, *04:02, the haplotypes DRB1*11:01-DQA1*05:01-DQB1*03:01, DRB1*13:01-DQA1*01:03-DQB1*06:03 and DRX-DQX/DRX-DQX genotype, formed by other than the DR3-DQ2 or DR4-DQ8 haplotypes, were significantly associated with T1D protection Despite the major racial Brazilian, even at the regional level, these results are similar to the majority of alleles, genotypes and haplotypes of HLA class II-related susceptibility or resistance to T1D, extensively described in the literature for Caucasian population. Children with age at diagnosis less than 5 years of age had significantly higher frequency of the heterozygous genotype DR3-DQ2/DR4-DQ8 compared to children with age at diagnosis than 5 years old. These results also demonstrate strong association of the genetic profile of the class II HLA for this age group, possibly associated with the severity and rapid progression to the onset of T1D. The knowledge of HLA class II genes may be useful in genetic screens that allow the prediction of T1D

Ectoparasitos associados a aves de um fragmento de Floresta Estacional Decidual no Rio Grande do Norte, Brasil

This study to aimed investigate the community of ectoparasites associated with birds in the Mata do Olho D água, in the municipality of Macaíba, Rio Grande do Norte (RN), Brazil, its structure and the ambiental and hosts influential variables on it, and to verify microhabitats preferences by species of chewing lice and feather mites. We examined 172 individuals belonging to 38 species of Passeriformes and non-Passeriformes. 12 new geographic records are reported and 11 host-parasite associations not yet known for chewing lice and feather mites species. Significant relationship was found between the abundance of chewing lice and the variables total length (r = 0.29, p <0.05) and exposed culmen (r = 0.38, p <0.05) of the hosts. A principal component (PC1) accounted for 90.1% of the hosts morphological variation was significantly influential on the abundance of chewing lice (p <0.05), indicating that the morphological characteristics of the hosts may be positively influencing the abundance of these ectoparasites. Significantly higher frequency of individuals with high loads of chewing lice was detected during the dry period (x ² = 8.5, p <0.05), corroborating studies that propose that birds of arid environments suffer as much pressure as those of parasitic humid environments. Analyses of null models of co-occurrence and niche overlap showed a high degree of structure in the feather mites and chewing lice assemblies, when compared with other groups, and preferences in the use of microhabitats by taxa identified. These results corroborate ecological theories in host-parasite systems, contribute to the knowledge of ectoparasites associated with neotropical birds, and the need for experimental studies, as well as further deepening the biology of these arthropods
