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

Efeito do ácido alfa-lipóico sobre biomarcadores de estresse oxidativo, inflamação e fatores de risco cardiovascular em hipertensos

Alpha-lipoic acid (ALA) is a potent antioxidant with favourable anti-inflammatory, metabolic and endothelial effects, and has been widely investigated due to its potential against cardiovascular risk factors. This study aimed to evaluate the effect of oral ALA supplementation on oxidative stress biomarkers, inflammation and cardiovascular risk factors in patients with hypertension. This is a double-blind placebo-controlled randomized clinical trial, where the intervention was evaluated prospectively comparing results in both groups. The sample consisted of 64 hypertensive patients who were randomly distributed into ALA group (n = 32), receiving 600 mg / day ALA for twelve weeks and control group (n = 32), receiving placebo for the same period. The following parameters were evaluated before and after intervention: lipid peroxidation, content of reduced glutathione (GSH), enzymatic activities of glutathione peroxidase (GPx) and superoxide dismustase, ultrasensitive C-reactive protein (hs-CRP), triglycerides, total cholesterol and fractions, fasting glucose and anthropometric indicators. There was a statistically significant reduction (p <0.05) in serum concentrations of total cholesterol, very low density lipoprotein (VLDL), high density lipoprotein (HDL), triglycerides and blood glucose. There was a reduction in body weight and waist, abdominal and hip circumferences in the group that received ALA. In addition, there was a statistically significant increase (p <0.05) in the contents of reduced glutathione (GSH) and glutathione peroxidase (GPx) in the group receiving ALA. Oral administration of ALA appears to be a valuable adjuvant therapy, which may contribute to decrease the damage caused by oxidative stress and other risk factors associated with the atherosclerotic process

Prevalência e fatores de risco de leptospirose bovina no Estado do Maranhão

Foram investigados a prevalência e os fatores de risco da leptospirose bovina no Estado do Maranhão. O Estado foi dividido em quatro circuitos amostrais com base em parâmetros de produção distintos que variam conforme os diferentes sistemas de produção, as práticas de manejo, a finalidade de exploração, o tamanho médio dos rebanhos e os sistemas de comercialização. Objetivou-se estudar as características epidemiológicas da leptospirose bovina no Estado do Maranhão, de modo a determinar a prevalência em bovinos e em rebanhos, detectar as sorovariedades de Leptospira spp. presentes, identificar os fatores de risco eventualmente associados à leptospirose em bovinos e diferenciar os circuitos pecuários entre si no que se refere à prevalência de leptospirose. A pesquisa foi realizada em 136 propriedades rurais pertencentes ao circuito I, no qual 841 fêmeas bovinas com idade igual ou superior a 24 meses foram analisadas; 238 do circuito II, com 2.582 fêmeas analisadas; 122 do circuito III, com 869 fêmeas analisadas; e 77 do circuito IV, com 540 fêmeas analisadas; no total, 573 propriedades e 4.832 fêmeas foram estudadas. A presença de anticorpos contra Leptospira spp. foi verificada pela técnica de soroaglutinação microscópica (SAM). Das 4.832 fêmeas bovinas analisadas, 1.904 (35,94%; IC 95% = 33,01% - 38,98%) foram reagentes. Das 573 propriedades analisadas, 380 (64,81%; IC 95% = 61,10% - 68,35%) foram consideradas positivas. As sorovariedades Hardjo e Wolffi foram as mais frequentes em todo o Estado. O circuito III foi o que apresentou menor prevalência de leptospirose em todas as comparações. As variáveis identificadas como fatores de risco de leptospirose foram: presença de equinos (p = 0,000), presença de capivaras (p = 0,034) e rebanhos bovinos com 32 ou mais fêmeas adultas (p = 0,002).

Úlcera de pressão em pacientes internados em um hospital universitário em Natal/RN: condições predisponentes e fatores de risco

The pressure ulcers (PU), also known as decubitus ulcers, are defined as injuries caused by the constant pressure exerted on a particular point of the body, causing impairment of blood supply with a decrease or interruption of tissue irrigation, causing occlusion of blood vessels and capillaries, ischemia and cell death. This is a descriptive study with longitudinal design, and panel type, with quantitative approach that aimed to examine the association between predisposing conditions (PC), intrinsic factors (IF) and extrinsic factors (EF) with the occurrence of PU, in hospitalized patients in the Intensive Care Unit (ICU), pain clinical, surgical clinical and neurology wards of a university hospital. The study population was composed of all patients who were restricted to bed during the period from December 2007 to February 2008. The study was approved by the Ethics Committee of HUOL / UFRN (No 135/07). The data-collection took place through a structured formulary of observation, data from medical records and physical examination of patients skins. The results were organized in SPSS 15.0 software, tabulated, categorized and analyzed by descriptive and inferential statistics. Of the 30 patients studied, 43.3% had been hospitalized in the pain clinical and surgical clinic wards, 20.0% in the ICU, 20.0% in the ICU / ward and 16.7% in neurology, being the length of hospitalization in those units of 7 to 18 days (63.3%) and from 19 to 30 days (36.7%), predominantly female and aged ≥ 60 years (60.0%). 19 PU were diagnosed in 43.3% of patients monitored, being 38.5% with one PU between 7 to 18 days and 46.2% with two or more between 19 to 30 days of hospitalization, showing significant relationship (ρ-value = 0029) between length of hospital stay and the number of PU. Was found an association of 35.7% of the PC (cardio-respiratory, hematological, metabolic and psychogenic), IF (age group, oedema, skin changes in humidity and change of body temperature) and EF (type of mattress and strength of body pressure) for all patients studied, statistically significant (ρ-value = 0001), between the average scores in patients with and without PU, with reason chance to 12.0 for the development of PU and there was moderate correlation ( r = 0618) in the presence of this association. Results show the influence of the multiplicity of factors and conditions on the occurrence of PU, which brings us to reflect on the assistance focused on prevention and reduction of these injuries which will encourage the reduction of hospitalization length, physical and psychological suffering, and the possibility of improving the clinical condition of the patient.

Hipertensão arterial e fatores de risco em servidores atendidos pelo departamento de assistência da Universidade Federal do Rio Grande do Norte

Systemic arterial hypertension is a multifactorial disease that contributes to the country´s high cardiovascular morbi-mortality rates. Considering that hypertension affects individuals in their most productive age while facing work and living risk factors, it is important to investigate its occurrence and predisposing factors in different occupational segments. The objective of this study was to identify the prevalence of hypertension among workers attended to in a medical service of a public university, their hypertension levels, the risk factors present, and their knowledge of the factors that influence the arterial pressure. The epidemiologic study was conducted in the Health Department of the Federal University of Rio Grande do Norte with 102 workers that sought care in the medical clinic during the months of March to May 2009. Data were collected by means of a questionnaire and measurements of systolic and diastolic arterial pressure (SAP and DAP) that were classified in stages according to the Brazilian Society of Hypertension and the degree of risk for cardiovascular events according to the criteria of the Brazilian Society for Cardiology. Data were analyzed using descriptive statistics. The workers were, on average, 54 years of age; the majority (67%) was male and had primary or middle educational level; they worked mainly in supplemental units and deanship offices conducting different functions such as security guards, administrative assistants, health auxiliaries and constructions workers; 48 (47%) of the workers identified themselves as hypertensive for 8 years on average, with the majority executing hard labor and administrative functions. Among the workers with hypertension, the number of the pressure levels classified as pre-hypertensive, stage I and II were: (12% in the SAP and 20% in the DAP); (16% in the SAP and 9% in the DAP); and (15% in the SAP and 5% in the DAP), respectively. The workers that did not identify themselves as hypertensive presented classifications with greater frequencies were: normal (16% in the SAP and 30% in the DAP); and pre-hypertensive (21% in the SAP and 16% in the DAP). The risk factors identified in more than 50% of the workers were: tobacco smoking, alcohol consumption and indices of being overweight, although physical activities are also present. Of the 48 workers diagnosed as hypertensive, those that had 5 risk factors present and limitrophic pressure levels (12%), in stage I hypertension (16%) and stage II hypertension (15¨%) were categorized as being in high risk for vascular events. The number of workers that indicated they had knowledge of the factors that influence their hypertension was less than 39% for each factor. It is concluded that there is a high prevalence of systemic arterial hypertension in the university workers, even amongst those already under treatment. They constitute a population at risk considering their age group, their work functions, and their inadequate life habits. Health care of these hypertensive workers that seek attention in the Health Department is an important aspect of the internal workers health policy in the institution. Educational interventions are recommended for the improvement of quality of life and of work in these workers

Exploração de fatores de risco para lesões no atletismo de alta performance

Os fatores de risco para instalação de lesões do esporte têm sido pesquisados no sentido de facilitar o entendimento sobre o assunto. Contudo, para altos níveis de performance, nos eventos de pista e campo do atletismo, são escassos os documentos que abordam o tema. Assim, a partir da possibilidade de reunir informações sobre a condição descrita, objetivou-se com o presente estudo a exploração de fatores de risco para lesões desportivas no atletismo, a partir de inquérito aplicado a atletas da elite mundial da modalidade. A população foi composta por 60 homens e 60 mulheres alocados em grupos conforme a especificidade de sua modalidade (velocidade, resistência, arremessos e saltos). Realizou-se entrevista utilizando-se de inquérito de morbidade referida, abordando questões sobre variáveis antropométricas e de treinamento, assim como lesões. Utilizou-se a técnica da análise de variância paramétrica para as variáveis antropométricas (idade, peso, estatura) e da técnica da análise de variância não paramétrica em relação às variáveis de treinamento (anos de treinamento e horas semanais). Para associação entre momento de lesão e especialidades, utilizou-se do teste de Goodman em nível de 5% de significância. Os resultados mostraram que houve elevada freqüência de lesões na modalidade em ambos os sexos. As taxas de lesão por atleta entrevistado foram de 0,92 (velocidade), 1,08 (resistência), 1,22 (saltos) e 1,20 (arremessos). Não houve diferença estatisticamente significante para as variáveis antropométricas e de treinamento em relação às provas, com exceção dos saltadores, que apresentaram diferenças para estatura e tempo de treinamento; nesse caso, os acometidos são mais altos ou praticam atletismo há menos tempo (P < 0,05). Concluiu-se que, para população estudada, o risco de lesão é acentuado, mas sem relação entre variáveis e presença de agravos, salvo para especialistas em provas de saltos, que apresentaram estatura e tempo de treinamento como fatores predisponentes à lesão.

Fatores de risco para síndrome metabólica em cadeirantes: jogadores de basquetebol e não praticantes

A atividade física tem sido sistematicamente estudada como fator preventivo no acometimento de enfermidades crônico-degenerativas, especialmente a síndrome metabólica e doenças cardiovasculares. Sedentarismo está relacionado à diminuição ou ausência de parâmetros mínimos de exigência física diária além do estado de repouso, sendo este fortemente associado à redução na condição de saúde dos indivíduos portadores de deficiência física. As respostas metabólicas do organismo mediante a ausência de determinada musculatura, ou sua inatividade pela falta de estímulos, conduzem a diferenças significativas na estruturação da composição corporal. Esta pesquisa teve como objeto o exercício físico regular e a condição de saúde de indivíduos portadores de deficiência física, através da determinação do perfil antropométrico e bioquímico sangüíneo, e ainda pela determinação da prevalência de fatores de risco para síndrome metabólica. Foram estudados 27 homens com paraplegia (T2-L1), portadores de seqüelas de poliomielite ou amputados, divididos em jogadores de basquetebol cadeirantes (JBC) e não jogadores de basquetebol cadeirantes (NJBC). Os JBC apresentaram circunferência de cintura menor comparada aos NJBC, 76,40±8,44 e 89,25±9,73 cm respectivamente (p<0,05). A pressão arterial sistólica foi significativamente maior nos NJBC 123,33±13,70 e 114,00±9,85 mmHg para JBC (p<0,05), não sendo verificada diferença para PAD. Os NJBC apresentaram valores superiores aos JBC para a bioquímica sangüínea de glicemia, TG, CT e frações, exceto para HDL-C (p<0,05). Os indivíduos NJBC apresentaram alta prevalência para fatores de risco da SM, sendo hipertensão arterial prevalente em 58,33% dos indivíduos, dislipidemia de HDL-C presente em 50% e circunferência de cintura acima da normalidade em 41,66%. Os achados do presente estudo sugerem um papel importante do exercício físico na prevenção da síndrome metabólica, embora estudos adicionais devam ser realizados para a melhor compreensão dos mecanismos que promovem a saúde dos deficientes físicos ativos.

Hipossalivação e seus fatores de risco em idosos funcionalmente independentes e não institucionalizados

The aim of this study was to investigate the risk factors related to hyposalivation among non-institutionalized independently living elderly people, living in Natal-RN, Brazil. The study was a control-case type and the data collection was accomplished by carrying a questionnaire, oral examination and a non-stimulated and stimulated sialometry. The cases were identified by values of salivary flow rate <0,1mL/min and stimulated ≤ 0,5 mL/min, and the controls were by observing the values of sialometry that were bigger than the previously defined parameters. Age and gender were used as pairing variables. The data were analyzed using X2 (α = 0,05) and odds ratio. The sample was composed of 98,1% female and 1,9% male, with mean age 68. There was not association between hyposalivation and the following studied variables: income, schooling, profession, dwelling conditions, domiciliary density, illness, number of teeth and use of prothesis. However, a link was found between hyposalivation and smoking frequency in the passet (OR=5,14), indicating that, referring to elderly people, the tabagism frequency habit was a risk factor to the studied condition. Therefore, refering to non-institutionalized independently elderly people, economic-social-demographic conditions, general and bucal health, diet and habits such as alcoholism have been not risk factors to hyposalivation. However, people that have been smoking have more risk to have the studied conditions

Edentulismo funcional e seus fatores de risco em adultos

The purpose of this study was to investigate the risk factors to the functional edentulism in adults aged 35 a 44 years old of Natal-RN, 278 adults took part in the study. They were all selected from a previous dental loss prevalence study thus being complemented by an active research. The study was a case-control based and data collection was made though a survey as well as with a clinical examination. The cases were identified through individuals with 20 or more teeth. Age and gender were used as variables of pairing off. The data was analyzed through chi-square, significant level of 95% to the checking of its force associations. The independent variables were grouped in three levels. The first one, more macro, is related to the region where the individual lives, which was also related to the second level, the family-based one, linked with a third level, at this low socio-economical level, where the domiciliary density was favorable, living in capital cities, regions with prime sanitary condicitions, with predominant possibility of accessing the public dental service, but in despite of this, only looking for this service when tooth ache is felt, where preferentially an aid dressing treatment is executed in detriment of preventive procedures. From all the samples, less than 25% of the individuals make use of tobacco and alcoholic beverages for quite a number of years. There was an association of functional edentulism with all the studied variables in a regional method. In the family-based with Critério Brasil (OR=4,45) and monthly wages (OR=9,62) and to an to an individual level, the associations took place with the current use of kind of attendance (OR=1,78), looks for dressing treatment (OR=2,51), does not look for preventive treatment (OR=3,31), pain as the main cause of demand (OR=1,92), previous treatment as the demanding reason for dental service (OR+0,28), interval of the last visit to the dental service (OR=1,35) and when advise was received (OR=1,66). It was noticed from the results that the functional edentulism is much more expressive in those families which live in environments with precarious social economical sanitary conditions. Such conditions seem to have a direct influence upon the family social economical conditions which are also shown in detriment to functional edentulism. In the same way, the collection of variants influence the social economical conditions of the individual, as well as the kind of dental service searched by them, the reason of the search and the interval of the last visit to the dental service were strong determiners to the functional edentulism. Beyond that, individual habits like the use of tobacco and its frequency on its previous use influenced in a significant way the existence of functional edentulism in the studied population

Influência de fatores de risco na prevalência de hábitos bucais deletérios em crianças de 0 a 5 anos na cidade do Natal-RN

Literature has demonstrated to the narrow relation between deleterious habits and the occurrence of malocclusion in minors of 5 years. The existence of these habits, however, already considered as risk factors, having also, its determinative ones, which present cultural dimensions and economic social, many of them related to the parents of the child, having in account that such habits if develop in phases in which the child establish a narrow relation of dependence. This study it had an objective to investigate the prevalence of deleterious buccal habits in children and its relation with the economic social and characteristics of the parents. It was developed an epidemiologist study of transversal character with interview, through daily pay-tested form, with 218 parents in the day of the National Campaign of Vaccination. In the cast of the variable that had composed the study, they had been used, as changeable dependents, the use of the baby's bottle, bottle and the digital suction, being considered as outcomes of the research. Amongst the independent variable, the economic social factors (type of occupation, number of children, civil state, sort, schooling and age) and staffs of the parents (self perception in oral health) had entered as the variable to be analyzed in the problems of the infantile odontology. The collected data had been submitted to the analysis descriptive and inferential statistics, being used the test qui-square and the analysis of the possibility reasons. As main results, it was found that breast feeding before the six months if presents as one of the main factors of risk for the use of baby's bottle (p< 0.001, OR= 2.8, I.C= 1.589 4.906), bottle (p< 0.001, OR= 3.7, I.C.= 2.076 6.624) and digital suction (p< 0.014, OR= 3.5, I.C.= 1.225 10.181). From the data found, one concludes that breast-feeding is considered a primordial factor for not the installation of deleterious oral habits and that the economic social and cultural factors can reflect in central way in the performance of this act

Fatores de risco para gagueira em crianças disfluentes com recorrência familial

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP)

Fatores de risco na gagueira desenvolvimental familial e isolada

OBJETIVO: investigar e comparar os achados dos fatores de risco para a cronicidade da gagueira em crianças com gagueira desenvolvimental familial e isolada. MÉTODOS: participaram 60 crianças de ambos os gêneros, divididas em dois grupos: GI - 30 crianças com gagueira desenvolvimental familial; GII - 30 crianças com gagueira desenvolvimental isolada. A coleta de dados foi realizada por meio do Protocolo de Risco para a Gagueira do Desenvolvimento - PRGD (Andrade, 2006), que considera os seguintes fatores de risco: idade, gênero, tipo de surgimento e tempo de duração das disfluências, tipologia das disfluências, fatores comunicativos e qualitativos associados, histórico mórbido pré, peri e pós natal, fatores estressantes que ocorreram próximo ao surgimento do distúrbio, histórico familial, reação pessoal, familiar e social e atitudes familiares. RESULTADOS: quando o grupo I (GI) foi comparado com o grupo II (GII), a única diferença estatisticamente significante foi com relação aos fatores estressantes que ocorreram próximo ao surgimento do distúrbio. CONCLUSÃO: os resultados confirmam a natureza complexa da gagueira, bem como a necessidade de se investigar os vários fatores considerados como de risco para o distúrbio, com intuito de melhorar a compreensão de suas possíveis etiologias.

Análise retrospectiva de fatores de risco e preditores de complicações intraoperatórias dos bloqueios do neuroeixo realizados na Faculdade de Medicina de Botucatu-UNESP

JUSTIFICATIVA E OBJETIVOS: As alterações cardiovasculares associadas aos bloqueios do neuroeixo apresentam interesse pela frequência com que ocorrem e porque algumas delas podem ser consideradas efeitos fisiológicos desencadeados pelo bloqueio do sistema nervoso simpático. O objetivo desta pesquisa foi avaliar as complicações cardiovasculares intraoperatórias e os fatores preditores associados aos bloqueios do neuroeixo em pacientes com idades > 18 anos submetidos a procedimentos não obstétricos, em um período de 18 anos, em hospital universitário de atendimento terciário-HCFMB-UNESP. MÉTODO: Foi realizada análise retrospectiva das seguintes complicações: hipertensão arterial, hipotensão arterial, bradicardia sinusal e taquicardia sinusal. Tais complicações foram correlacionadas com técnica anestésica, estado físico (ASA), idade, sexo e comorbidades pré-operatórias. Para a análise estatística, foram utilizadas o teste de Tukey para comparações entre proporções e regressão logística. RESULTADOS: Foram avaliados 32.554 pacientes submetidos a bloqueios do neuroeixo e houve 4.109 citações de hipotensão arterial, 1.107 de bradicardia sinusal, 601 de taquicardia sinusal e 466 de hipertensão arterial no período intraoperatório. Hipotensão foi mais frequente nos pacientes submetidos à anestesia subaracnoidea contínua (29,4%, OR = 2,39), com idades > 61 anos e do sexo feminino (OR = 1,27). CONCLUSÕES: Hipotensão e bradicardia intraoperatórias foram complicações mais frequentes, sendo que a hipotensão arterial esteve relacionada à técnica anestésica (ASC), faixa etária elevada e sexo feminino. Taquicardia e hipertensão arterial podem não ter sido diretamente relacionadas aos bloqueios do neuroeixo.
