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

Síndrome metabólica e fatores de risco relacionados em crianças e adolescentes com excesso de peso na cidade do Natal

Nas últimas décadas, houve grande aumento da prevalência de obesidade, inclusive na faixa etária pediátrica. Com isso, aumentou o número de crianças e adolescentes afetados por síndrome metabólica (SM), diabetes tipo 2 (DM2) e doenças cardiovasculares (DCV), doenças anteriormente consideradas quase exclusivas de adultos. Os objetivos do estudo foram identificar e correlacionar marcadores antropométricos (IMC- índice de massa corpórea, CA- circunferência abdominal, RCQ- razão cintura/quadril, RCArazão cintura altura e PSE- prega subescapular), PAS e PAD- pressão arterial sistólica e diastólica, respectivamente, e laboratoriais (CT- colesterol total, HDL, LDL, TGL- triglicérides, I/G- razão insulina glicose, HOMA- homeostatic model assessment for insulin resistance) de risco para o desenvolvimento de SM e observar a sua prevalência em crianças e adolescentes com excesso de peso. Foi conduzido estudo transversal, em amostra aleatória, de conveniência, onde foram avaliadas 60 crianças e adolescentes com excesso de peso, atendidas no ambulatório de endocrinologia pediátrica do Hospital de Pediatria da Universidade Federal do Rio Grande do Norte (UFRN) com idade mínima e máxima de 7 e 15 anos, de maio de 2009 a abril de 2010. Foram admitidos os indivíduos que apresentavam sobrepeso (IMC P > 85 e < 95) ou obesidade (IMC P > 95) (CDC, 2000) e história familiar positiva para DM2 em parentes de primeiro ou segundo grau ou algum dos sinais de resistência insulínica (acantose, hipertensão arterial, dislipidemia, síndrome de ovários policísticos). 2 O componente individual para SM mais prevalente foi o percentil da CA ≥ 90 (58,3%), seguido de HDL ≤ 40 mg/dl (36,6%). Na regressão linear simples, observaram-se as variações para mais nos parâmetros laboratoriais e de PA para cada unidade de aumento de IMC, CA, RCA, RCQ e PSE, sendo significantes as seguintes correlações: CA com TGL, HOMA IR, I/G, PAS e PAD; RCQ com TGL, HOMA, I/G, LDL e glicemia; RCA com TGL; PSE com TGL, HOMA-IR, I/G e PAS; e IMC com HOMA IR, I/G, PAS e PAD. De acordo com os critérios da IDF (Federação Internacional de Diabetes International Diabetes Federation) 2007, o diagnóstico de SM foi encontrado em seis indivíduos (10%). Do total, oito (13,3%), estavam em situação de sobrepeso e 52 (86,6%), obesos. As evidências de correlação CA e RCQ, medidas de obesidade centrípeta, com vários marcadores como TGL e HOMA, já sabidamente relacionados à SM, chamam atenção para a necessidade de utilização dessas medidas de forma mais rotineira na prática pediátrica, por serem de fácil obtenção, baixo custo e método não invasivo. Os valores de CA, RCQ, RCA e PSE, quando elevados devem justificar maior detalhamento na avaliação laboratorial de possível resistência insulínica. É importante a identificação de crianças e adolescentes que preencham os requisitos para o diagnóstico da SM, pois são indivíduos de maior risco metabólico e devem ser adequadamente acompanhados.

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

Determinação dos fatores neuroepidemiológicos das crises convulsivas em recém nascidos internados em unidades de terapia intensiva

O objetivo do nosso projeto foi determinar as características dos recém nascidos com crises convulsivas internados em unidades de terapia intensiva. Foi realizada uma pesquisa multicêntrica, observacional, prospectiva, cuja população alvo foi os recém nascidos com crises convulsivas internados em unidades de terapia intensiva, envolvendo equipe multidisciplinar constituída por neurologista infantil, neonatologistas, intensivistas pediátricos, enfermeiros, técnicos de enfermagem e fisioterapêutas. As crises foram definidas pelo critério clínico, com classificação de Volpe. Variáveis relacionadas à gestação, ao parto, características dos recém nascidos, aspectos das crises convulsivas e mortalidade foram analisadas. Estatística: descritiva (freqüências, medidas de tendência central e dispersão) e análise (teste de probabilidade, teste de risco e de acurácia). Comparamos as crises clínicas entre os recém nascidos de termo e pretermo e observamos diferenças com significância estatística na idade de início das crises, mais tardia nos prematuros, na etiologia predominante: hemorragia peri-intraventricular no prematuro e encefalopatia hipóxico-isquêmica no termo e tipo clínico de crise, clônica no pretermo e sutil no termo. Os testes de acurácia utilizados para determinar se o tipo clínico de crise convulsiva é predictor da etiologia da mesma não revelaram resultados positivos. Quanto às características associadas à mortalidade de prematuros com crise convulsiva, observamos associação entre ventilação mecânica e pneumonia com a mortalidade. Existem diferenças clínicas quando comparamos os recém nascidos pretermo e de termo com crises convulsivas, confirmando dados da literatura

Candidíase vulvovaginal: sintomatologia, fatores de risco e colonização anal concomitante

Post-menarche patients with clinical signs of vulvovaginitis were analyzed in this study, whose aims were the following: identify the frequency of C. albicans and non C. albicans species and negative results, correlate the vaginal culture for yeast with risk factors and symptomatology; compare positive and negative results for yeast in the vaginal and anal cultures; compare the positive results for C. albicans with other results found in the vaginal and anal cultures; and compare concomitant positivity for C. albicans and non C. albicans in the vaginal and anal cultures. Sample selection occurred between May, 2003 and May, 2005, and included 99 patients from Natal, Brazil. The laboratory methods used consisted of CHROMagar Candida culture medium, thermotolerance test at 42-45°C and hypertonic NaCL, in addition to the classic methods of carbohydrate assimilation and fermentation. We used absolute numbers, percentages, means of central tendency, chi-squared test (χ2) with Yates correction, Fisher s exact test and odds ratio for statistical analysis. The most frequent species was C. albicans in 69% of the cases. The positivity for Candida spp showed an association with the use of tight-fitting intimate clothing and/or synthetics, allergic diseases and the occurrence of itching, leukorrhea and erythema. Anal colonization increased the likelihood of vaginal contamination by 2.8 and 4.9 times, respectively, for Candida spp and C. albicans. When compared to the other species, C. albicans-positive anal colonization increased by 3.7 times the likelihood of vaginal positivity. These data suggest likely vaginal contamination originating in the anus

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

Identificação e fatores de virulência de Candida spp isoladas da cavidade bucal de transplantados renais do hospital universitário Onofre Lopes em Natal-RN

Despite Candida species are often human commensals isolated from various oral sites such as: tongue, cheek and palatal mucosa plus subgingival region, there are some properties linked to the organism commonly known as virulence factors which confer them the ability to produce disease. Oral candidiasis is one of the main oral manifestations reported in literature related to kidney transplant patients. The objectives of the present study were to identify and investigate virulence factors of yeasts isolated from the oral cavity of kidney transplant recipients admitted at the Hospital Universitário Onofre Lopes, in Natal RN. Seventy Candida species isolated from 111 kidney transplant recipients were investigated in this study. Identification of the isolates was performed by using the evidence of germ tube formation, hypertonic broth, tolerance to grow at 42°C, micromorphology and biochemical profiles. We observed a high rate of isolation of yeasts from the oral cavity of kidney transplant recipients (63.1%) being C. albicans was the most prevalent species. Oral candidiasis was diagnosed in 14.4% of transplant recipients. We evaluated virulence properties of the isolates regarding to: biofilm formation on polystyrene microplates as well as XTT reduction, adherence to acrylic resin and human buccal epithelial cells and proteinase activity. Most isolates were able to form biofilm by the method of adhesion to polystyrene. All isolates of Candida spp. remained viable during biofilm formation when analyzed by the method of XTT reduction. The number of CFU attached to the acrylic resin suggested high adherence for C. parapsilosis. C. albicans isolates showed higher median adherence to human buccal epithelial cells than non-C. albicans Candida isolates. Nevertheless, this difference was not statistically significant. C. dubliniensis showed low ability to adhere to plastic and epithelial cells and biofilm formation. Proteolytic activity was observed for all the isolates investigated, including the unique isolate of C. dubliniensis. There was a statistically significant association between proteinase production and the presence of oral candidiasis. Studies related to oral candidiasis in renal transplant recipients are limited to clinical and epidemiological data, but investigations concerning Candida spp. virulence factor for this group of individuals are still scarce. We emphasize the importance of studies related to virulence factors of yeasts isolated from this population to contribute to the knowledge of microbiological aspects of oral candidiasis

Características genotípicas e fenotípicas de Candida Albicans isoladas da cavidade bucal de pacientes transplantados renais com ênfase na ação do extrato bruto de Eugenia uniflora em fatores de virulência

Candida albicans is a diploid yeast that in some circumstances may cause oral or oropharyngeal infections. The investigation of natural products is mandatory for the discovery of new targets for antifungal drugs development. This study aimed to determine the genotypes of 48 clinical isolates of C. albicans obtained from the oral cavity of kidney transplant patients from two distinct geographic regions of Brazil. In addition, we investigated three virulence factors in vitro: phospholipase activity, morphogenesis and the ability to evade from polymorphonuclear neutrophils. The expression of these virulence factors in vitro was also investigated in the presence of the crude extract of Eugenia uniflora. The genotype A was the most prevalent (30 isolates; 62.5%), followed by genotype C (15 isolates; 31.5%) and genotype B (3 isolates; 6.25%). When microsatellite technique with primer M13 was applied, 80% of the isolates from the South were placed within the same cluster. All Genotype C strains were grouped together within two different clusters. Genotype C was considered more resistant to PMNs attack than genotypes A and B. Strains isolated from the South of Brazil showed higher ability to combat PMNs phagocytosis. We found a high rate of genotype C strains isolated from the oral cavity of this group of patients. The crude extract of E. uniflora inhibited proper hypha formation and phagocytosis by PMNs, but had no significant effect on phospholipase activity. This study characterized oral C. albicans strains isolated from kidney transplant recipients and will contribute for the better understanding of the pathogenesis and alternative therapeutics for oral candidiasis

Fatores que afetam a germinação e a emergência de Xanthium strumarim L.: dormência, qualidade da luz e profundidade de semeadura

Foram conduzidos três ensaios com o objetivo de estudar os efeitos de diferentes métodos de quebra de dormência das sementes, da qualidade da luz e da profundidade de semeadura na germinação e emergência do Xanthium strumarim L. (carrapichão). No primeiro ensaio, sob condições de câmara de crescimento, os tratamentos constaram de 5 métodos de quebra de dormência: mecânico (lixa), químico (H2SO4 conc. por 10 min.), pré-tratamento em água (imersão por 2 horas), físico (choque térmico: água à 80oC por 2 min.) e testemunha, que proporcionaram 100%, 93%, 93%, 87% e 80% de germinação, respectivamente, sem haver diferença estatística entre os mesmos. O pré-tratamento em água apresentou menor índice de velocidade de germinação (IVG) e os demais não diferiram significativamente entre si. No segundo ensaio, também sob condições de câmara de crescimento, os tratamentos de qualidade da luz constaram de 6 filtros de luz, que resultaram nas seguintes porcentagens de germinação: azul - com refletividade máxima a 450 nm (13%), verde-500 nm (33%), vermelho-700 nm (13%), vermelho/distante-760 nm (7%), ausência de luz (26%) e transparente - sem absortividade na região de 380 a 760 nm (testemunha, 73%), indicando sensibilidade das sementes à qualidade de luz. No terceiro ensaio, sob condições de casa-de-vegetação, os tratamentos foram diferentes profundidades de semeadura (0 a 20 cm, em intervalos de 2 cm), sendo que o máximo de emergência ocorreu no intervalo de 0 a 8 cm, no qual foi observado 67% de emergência do carrapichão, com maior índice de velocidade emergência (IVE), sendo que após os 16 cm, praticamente não houve emergência.

Análise espacial dos fatores da equação universal de perda de solo em área de nascentes

O objetivo deste trabalho foi avaliar a perda de solo de área de nascentes da Microbacia do Córrego do Tijuco, SP. Foi utilizada a análise espacial dos fatores da equação universal da perda de solo (EUPS), em integração com análise de componentes principais e geoestatística. A perda de solo média, estimada para a área, foi de 118,5 Mg ha‑1 por ano, considerada alta. Próximo à zona urbana, houve alta interação dos fatores erosividade da chuva e práticas conservacionistas, o que evidencia grande perda de solo, em razão da concentração da água proveniente da camada impermeabilizada urbana, com alta velocidade de escoamento. Nos divisores de águas, a atuação da erodibilidade foi proeminente, em contraste com o fator topográfico. Foram observadas áreas com atuação conjunta destes fatores, inclusive em locais de inclinação suave, porém com alto potencial natural de erosão. A interação das análises multivariadas e geoestatística permite a estratificação da área, identifica locais com propriedades específicas quanto à perda de solo, e espacializa os fatores do processo erosivo e suas interações ao longo do relevo.
