The preeclampsia is a disease that evolves to high death rate for the mother and for the fetus. The incidence of this disease in the world is variable and there are no data of this disturb in the Brazilian population. This paper had the objective to determine the incidence and risk factors for development of hypertensive disorders of pregnancy in a neighborhood in Natal, RN, Brazil, taking place a prospective study, cohort type, with the objective of evaluating the entire pregnancy of 242 women that got pregnant between 2004-2007. The incidence of hypertensive disorders was of 17%, while the incidence of preeclampsia was of 13.8%. The age average of women that developed the hypertensive disorders was of 27.4 years (SD±.9), whilst those that developed preeclampsia was of 26.6 (SD ±7.8) years and the normotensive was of 23.9 (SD±5.8) (p=0.002). It is noted a significant increase of the hypertensive disorder with age (p=0.0265). The gestational age for those who developed preeclampsia was lower than the women that developed normotensive pregnancy (p=0.0002). The body mass index (BMI) of the group of women that developed the hypertensive disorder was of 25.8 (SD±3.9), significantly higher than the group of normotensive women with 23.5 (SD±3.7) (p=0.02). The levels of triglycerides and cholesterol tended to be higher on women with preeclampsia than on normotensive, p=0.0502 and p=0.0566, respectively. Six (6) women presented with severe preeclampsia and one (1) developed HELLP Syndrome. The resolution of the pregnancy was performed by cesarean section in 70% of women that developed hypertensive disorders, whilst the normotensive was of 23.6% (p<0.0001). A subgroup of the studied subjects was reassessed one year after labor, revealing that 50% of the patients were still hypertensive. There were no larger complications nor mother death during labor. The incidence of hypertensive disorders are above the levels noted in other studies and 30% of the women were within the poles of greater risk for the hypertensive disorders; the elevated BMI in the beginning of the pregnancy is a risk factor for hypertensive disorder. The risk of severe complication in preeclampsia is high, with imminence of eclampsia occurring in 20.1% of women who developed hypertensive disorder of pregnancy. The adequate prenatal care and the opportune labor assistance may minimize the complications of the pregnancy hypertension and avoid mother death, although the risk of women remaining hypertensive is elevated

OBJECTIVE: Preeclampsia is a disease that can lead to a high maternal and infant morbidity. Worldwide, the incidence of this disease is highly variable and there is no data on this disorder in the Brazilian population. This study aimed at determining incidence and risk factors in the hypertensive disorders during pregnancy in a neighborhood of Natal, in addition to observing the evolution of these disorders one year and five years after delivery. METHODS: Prospective cohort study to assess the outcome of pregnancies of 242 women who became pregnant between 2004-2007 in the neighborhood of Bom Pastor in the city of Natal, state of RN, Brazil. Five years after delivery, there was an active search of thirty-nine (39) women who became pregnant and had a hypertensive disorder during pregnancy and/or pré-eclâmpsia, out of the total of 242 participants in the initial study. We administered a structured questionnaire to obtain basic information about the current clinical situation of patients and occurrences of subsequent pregnancy and presence of hypertensive disorders during pregnancy. We also searched for information on the use of hypotensive drugs and contraceptives. The following characteristics were checked and recorded: a) current weight, b) blood pressure c) body mass index - BMI, and we collected biological samples (blood and urine) for measurement of biochemical parameters and evaluation of microalbuminúria. Finally, we monitored the ambulatory blood pressure (ABP), which uses the method of automatic measurement of heart rate, systolic and diastolic blood pressure and an average of the two for the period of 24 hours. RESULTS: Out of 218 women who completed the study, the incidence of hypertensive disorders was of 16.9% (37 out of 218), while the incidence of preeclampsia was 13.8% (30 of 218). Women with preeclampsia had a BMI (body mass index) averaged of 25.3 (± 4.8) while this ratio in normotensive women was of 23.5 (± 3.7), p = 0.02. The risk of preeclampsia rises with age (OR 1084 p = 0.0034) and with a family history of hypertension (OR 2.6 p = 0.01). The follow-up one year after delivery revealed that 50% of women with hypertensive disorders in pregnancy remained hypertensive. High BMI was also observed after 5 years of delivery. CONCLUSIONS: an elevated BMI, age above 35 years and excessive weight gain during pregnancy were associated with hypertension in the long term in patients with prior preeclampsia. History of preeclampsia increases the risk of chronic hypertension

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

The development of complex diseases such as preeclampsia are determined by both environmental and genetic factors, but there is also interaction among these factors. Preeclampsia is a pregnancy-specific disorder characterized by de-novo hypertension and proteinuria after 20th week of gestation. There is a broad spectrum of clinical presentations related to hypertensive disorders of pregnancy (HDP) that can range from mild preeclampsia to eclampsia (seizures) or HELLP syndrome (Hemolysis, Elevation of Liver enzymes, Low Platelets). Those clinical outcomes might be linked to different pathological mechanisms. Our work aims to identify factors (i.e. genes and environmental) associated with the HDP’s clinical spectrum. Using a case-control approach, we selected a total of 1498 pregnant women for epidemiological and genetic studies, encompassing 755 normotensive (control); 518 preeclampsia; 84 eclampsia; and 141 HELLP. Women were genotyped for 18 SNPs across 5 candidate genes (FLT1, ACVR2A, ERAP1, ERAP2 and LNPEP). For the environmental factors, we found maternal age, parity status and pre-gestational body mass index as important risk factors associated with disease. Genes were associated in a phenotype-specific manner: ACVR2A with early preeclampsia (rs1424954, p=0.002); FLT1 with HELLP syndrome (rs9513095, p=0.003); and ERAP1 with eclampsia (rs30187, p=0.03). Our results suggest that different genetic mechanisms along with specific environmental factors might determine the clinical spectrum of HDP. In addition, phenotype refinement seems to be an essential step in the search for complex disease genes

Para avaliar os efeitos de diferentes tempos de pré-condicionamento isquêmico (IPC) em translocação bacteriana intestinal (BT). MÉTODOS: Trinta ratos Wistar pesando 280 ± 27g foram divididos em cinco grupos. No grupo IV (n = 6), a laparotomia foi realizada e a artéria mesentérica superior foi obstruído por um microclampe atraumática durante 30 minutos. Nos quatro grupos de pré-condicionamento (n = 6 cada) antes dos 30 minutos de isquemia-reperfusão (I / R), os ratos foram submetidos a IPC para duas, cinco, dez e 15 minutos, seguido pelo mesmo momento da reperfusão. A fim de avaliar se o tempo de pré-condicionamento influenciaram o surgimento de translocação bacteriana, as amostras de nódulos linfáticos mesentéricos, fígado e baço foram colhidas em condições estéreis, 24 horas após os procedimentos para a quantificação de unidades formadoras de colónias de bactérias por grama de tecido (CFU / g). O sangue foi recolhido para a medição de citoquinas. RESULTADOS: No grupo I / R, o total de CFU / g em gânglios linfáticos mesentéricos, baço, fígado, bem como o soro de TNF-a, IL-1A e IL-6 foram significativamente mais elevados do que nos outros grupos (p <0,05). Pré-condicionamento por 15 minutos significativamente atenuada BT e citocinas séricas quando comparado a outros períodos de pré-condicionamento (p <0,05). CONCLUSÃO: Nossos dados sugerem que o pré-condicionamento como um fator chave para reduzir a translocação bacteriana intestinal em I / R. Numa escala de dois a 15 minutos, o melhor tempo de pré-condicionamento isquémico pela atenuação da translocação bacteriana foi de 15 minutos

Compounds derived from fungi has been the subject of many studies in order to broaden the knowledge of their bioactive potential. Polysaccharides from Caripia montagnei have been described to possess anti-inflammatory and antioxidant properties. In this study, glucans extracted from Caripia montagnei mushroom were chemically characterized and their effects evaluated at different doses and intervals of treatment. It was also described their action on colonic injury in the model of colitis induced by 2,4,6-trinitrobenzene sulfonic acid (TNBS), and its action on cells of the human colon carcinoma (HT-29). Compounds extracted of C. montagnei contain high level of carbohydrates (96%), low content of phenolic compounds (1.5%) and low contamination with proteins (2.5%). The (FT-IR) and (NMR) analysis showed that polysaccharides from this species of mushroom are composed of α- and β-glucans. The colonic damage was evaluated by macroscopic, histological, biochemical and immunologic analyses. The results showed a reduction of colonic lesions in all groups treated with the glucans of Caripia montagnei (GCM). GCM significantly reduced the levels of IL-6 (50 and 75 mg/kg, p < 0.05), a major inflammatory cytokine. Biochemical analyses showed that such glucans acted on reducing levels of alkaline phosphatase (75 mg/kg, p < 0.01), nitric oxide (p < 0.001), and myeloperoxidase (p < 0.001). These results were confirmed microscopically by the reduction of cellular infiltration. The increase of catalase activity suggest a protective effect of GCM on colonic tissue, confirming their anti-inflammatory potential. GCM displayed cytostatic activity against HT-29 cells, causing accumulation of cells in G1 phase, blocking the cycle cell progression. Those glucans also showed ability to modulate the adhesion of HT-29 cells to Matrigel® and reduced the oxidative stress. The antiproliferative activity against HT-29 cells displayed by GCM (p <0.001) can be attributed to its cytostatic activity and induction of apoptosis by GCM

The fucoidan from Fucus vesiculosus is known for having diverse biological properties. This study analyzed the therapeutic action of populations of commercial fucoidan (F. vesiculosus) on zymosan-induced arthritis. Three populations of fucoidan were obtained after acetone fractionation; these were denominated F1 (52.3%), F2 (36.7%) and F3 (10.7%). Chemical analyses showed that F1 contained the largest amount of sulfate ion. The electrophoretic profile shows that the commercial or total fucoidan (TF), different from the other fucoidans and from glycosaminoglycan patterns, is quite polydisperse, which indicates that it is composed of a mixture of sulfate polysaccharides. On the other hand, the fucoidans obtained from TF showed only an electrophoretic band with much lower polydispersion than that observed for TF. Fucoidan F2 showed a migration between fucoidans F1 and F3. Owing to the small amount of mass obtained from F3, we used only fucoidans F1 and F2 in the induced arthritis tests. After 1 hour of induction, we administered F1 or F2 (10, 25 and 50 mg/kg i.p.) or diclofenac sodium (10 mg/kg i.p.) or lumiracoxib (5 mg/kg o.a.) or L-NAME (30 mg/kg i.p.). After 6 hours, we performed analyses of cell influx and nitrite levels in addition to histopathological analysis. Fucoidans F1 and F2 were more potent both in decreasing the number of leukocytes and the amount of nitric oxide found in the synovial fluid. This indicates that the anti-inflammatory mechanism of these fucoidans is not only related to selectin block, but also to nitric oxide synthesis inhibition

The decoction of Brazilian pepper tree barks (Schinus terebinthifolius, Raddi), is used in medicine as wound healing and antiinflamatory. Once extracts from this plant are used for acceleration of scar s process, it is important to study their mutagenic and genotoxic potential. In previous works in our laboratory, it was observed mutagenicity caused by the decoction when in high concentrations. Among the chemical compounds of this plant that could be able to induce mutation, the flavonoids were the only group that was referred to have either an oxidant or antioxidant potential. The flavonoids were isolated, purified and quantified by adsorptive column chromatography under silica gel, bacterial and in vitro genotoxic tests were realized to determine if the flavonoids were the responsible agents for this mutagenicity found. The tests realized with plasmidial DNA were indicative that the flavonoids are probably genotoxic, due to the presence of correlation between increase of the flavonoid concentration and in plasmidial DNA double strand breakage visualized in agarose gel, as well as they were capable to generated abasic sites shown by the in vitro treatment with exonuclease III. The same tests with plasmidial DNA in the presence of copper [10 µM] and of a Tris-HCl pH 7.5 [10 µM] buffer were realized with the isolated flavonoids to determine if there would be or not participation of reactive oxygen species (ROS). The transformation of plasmidial DNA in different bacterial strains proficient and deficient in DNA repair enzymes in the presence or not of a Tris-HCl buffer, suggests that the enzymes that repair oxidative lesions are necessary to repair the lesions generated by the flavonoids and that ROS are generated and are necessary to promote the lesions. Bacterial tests with Escherichia coli strains of the CC collection (deficient or not for DNA repair enzymes), showed that the flavonoids are able to increase the frequency of mutations, mainly in strains mutated in repair enzymes (MutM, MutY-glicosylases and double mutant), suggesting that these agents are responsible for the enhancement in the mutation rate. In order to determine the mutation spectrum caused by the flavonoids of the Brazilian pepper tree stem bark, plasmidial DNA previously treated with the flavonoids were transformed in bacterial strains deficient and proficient in the DNA repair enzymes, followed by a blue-white selection with X-gal, DNA amplification by PCR and sequencing the positive mutant clones. Analysis of the mutants obtained from strains CC104, CC104mutM, CC104mutY, CC104mutMmutY, BW9101, BW9109 indicated a predominance of some mutations like G:C to C:G that can be correlated with the origin of 8-oxoG, due to oxidative lesions caused by the flavonoids. So it can concluded that the flavonoid isolated or in fractions enriched on them are genotoxic and mutagenic, and their mutations are predominantly oxidative, mediated by ROS, and the lesions are recognized by the BER system. In this way it is proposed that the flavonoids can act in two different ways to generate the DNA lesion: 1. in a Fenton-like reaction, when the flavonoid are in the presence of metal ions and that together with the water generate ROS that promotes the DNA lesions; 2. in another way the lesions can be generated by the formation of ROS due to the internal chemical structure of the flavonoid molecule due to the quantity and location of hydroxyl groups, and so producing the DNA lesions, those lesions can be directly (suggested by the in vitro experiments) or indirectly done (supported by the experiments using the CC bacterial strains)

Hypertensive syndromes in pregnancy (HSP) are configured as one of the major complications in the pregnancy and postpartum period and can lead premature newborn and subsequent hospitalization of the newborn to the Neonatal Intensive Care Unit (NICU). This study aimed to analyze the perceptions, meanings and feelings of mothers on the hypertensive syndromes in pregnancy and premature obstetric labor. The research was qualitative and has a theoretical methodological the Social Representations Theory(SRT) in the approach to the Central Nucleus Theory. The study included 70 women, mean age 29 years, predominantly school to high school, most of them married or in consensual union, primiparous and prevalence of cesarean delivery occurred between 32 and 37 weeks of pregnancy.The data were collected from may to december 2008 in the Maternity School Januário Cicco in Natal , and obtained through the following instruments for data collection: questionnaire including questions about socio-demographic status; the Free Words Association Test (FWAT) and and verbalized mental image construction used three stimuli: such as pregnancy with high blood pressure, preterm birth and NICU, and interview with the following guiding question: what it meant for you to have a pregnancy with high blood pressure and consequently the birth of a premature baby? Data analysis was performed using multi-method obtained from the data processing by EVOC (Ensemble Programmes Permettant L 'Analyze des Évocations) and ALCESTE (Analyse Lexicale par Contexte d'un Ensemble de Segment de Texte) and thematic analysis in categories. The results will be presented in four thematic units under the following representative universes: HSP, prematurity as a result of HSP, NICU and the social representations of mothers on the hypertensive disorder of pregnancy sequenced premature birth and hospitalization of the child in the NICU. The results obtained by multimethod analyses showed similar constructions and point to death as the central nucleus and negative aspects, coping strategies, need of care, knowledge about the disease, fragility and meanings of the NICU as peripheral elements. It is considered that the perceptions, meanings and feelings of puerperal women in relation to HSPs and to premature delivery are a negative social representation, with representational elements that may have influenced the adverse effects on the disease and its consequences. We suggest action on the peripheral elements of this representation, with adequate orientation, early diagnosis, effective conduct, receptive attitude on the part of the team, health promotion measures and effective public policies, in order to improve the care provided to puerperal women, making them feel welcome and minimizing their suffering

The general aim of the research was to comprehend the Social Representations constructed by the man in the face of his companion s risk pregnancy caused by hypertensive syndromes. The study is of exploratory and descriptive character in a qualitative approach developed at two public maternity hospitals, both located in Natal-RN, with 65 men whose wives had undergone high-risk pregnancy. The project was submitted to the Ethics on Research Committee of the Federal University of Rio Grande do Norte, Brazil (CEP-UFRN), with favorable report no. 81/07. For data collection, the following multimethods were employed: a word free association test; a projective test for registering mental images; and a semistructured interview schedule. The speech contents were analyzed in accordance with the Theory of Social Representations and complemented by the Central Nucleus Theory. The discussion of the results was grounded on literary findings of the companion s participation in pregnancy as well as in risk pregnancy associated with hypertensive syndromes. The data showed fear as representation s central nucleus, while recollections of that feeling referred to death of both companion and child in addition to fear of the unknown. The categories preoccupation and carefulness, other feelings, and clinical picture of the disease represented components of the peripheral nucleus. The results concerning mental images followed the same category criteria of the word free association test fear, other feelings, preoccupation, carefulness, and clinical picture of the disease. After being processed in accordance with the principles of content analysis, the statements originated three thematic unities: fear and insecurity in the presence of the companion s risk pregnancy; attitudes of carefulness to the risk pregnancy of the partner; and humanized assistance during the companion s risk pregnancy. Considering the results, the conclusion is that the partner s risk pregnancy caused by hypertensive syndromes represents, for the man, feelings of fear, preoccupation, insecurity, lack of acceptance and information, as well as attitudes of carefulness. The results reveal necessity of reorganizing the obstetric assistance with an eye to including the man as participant in the reproductive process. That demands extension of humanized carefulness to the companion with a view to make him an active coadjutor in the assistance of high-risk pregnant

Introdução: A obesidade e suas formas extremas como a forma mórbida, vem assumindo preocupação nos sistemas de saúde pública e é atualmente considerado um dos mais importantes agravos de saúde no mundo desenvolvido. Acarreta repercussões em várias partes do corpo, com potencial para interferir negativamente também na função reprodutiva, recentemente sendo mais estudado na população masculina. Objetivo: avaliar parâmetros hormonais e seminais da função reprodutiva em um grupo de homens obesos mórbidos, antes e após 6 meses da perda de peso induzida pela cirurgia bariátrica. Métodos: Inicialmente, de uma amostra de 36 pacientes com idade entre 18 e 40 anos e índice de massa corporal (IMC) ≥40 Kg/m2, apenas 1 caso foi excluído por ser portador de hiperprolactinoma e outros 24 pacientes não completaram todo o protocolo de avaliação laboratorial solicitada. Um total de apenas 11 pacientes completou o protocolo. Todos foram previamente avaliados por uma equipe multidisciplinar. O grupo selecionado foi submetido a avaliação seminal e dosagens hormonais de testosterona total(TT), FSH e LH. Os parâmetros foram reavaliados após 6 meses de realização da cirurgia pela técnica de Y-em-Roux, para análise dos efeitos da perda de peso sobre os parâmetros da função reprodutiva. Resultados: No grupo selecionado ao estudo, os exames pré-operatórios mostraram um grupo heterogêneo de resultados. Após seis meses do tratamento cirúrgico, a perda ponderal foi significativa no grupo analisado, com redução do IMC de mediana 46 Kg/m2para mediana de 36 Kg/m2(p=0,03). Em relação ao perfil hormonal, houve elevação significativa do nível sérico de TT com mediana de 187ng/ml no período pré-operatório para 457 ng/ml (p=0,02) no período pós-operatório. Entre os períodos pré e pós-operatório, não foram observadas alterações significantes do FSH (2,70 mIU/ml para 3,31 mIU/ml, p=0,79), LH (4,82 mIU/ml para 3,00mIU/ml, p=0,39), concentração espermática (38milhões/ml para 31milhões/ml, p=0,88) e motilidade A+B (50% para 50%, p=0,89).Conclusão: A redução ponderal decorrente da cirurgia em obesos mórbidos parece levar a uma elevação dos níveis de testosterona total, sem alterações nas demais provas de avaliação reprodutiva. Estudos adicionais com casuística maior e múltiplos parâmetros são necessários para esclarecimento definitivo do impacto da obesidade e da perda de peso induzida pela cirurgia sobre a função reprodutiva masculina

Objective: To determine the prevalence of auditory manifestations in individuals with hypertension and analyze the association between hearing loss, systemic hypertension and quality of life in hypertensive patients. Method: This was a prospective, observational, case-control study, carried out from June 2010 to December 2013 at the University Hospital Onofre Lopes, in Natal, Brazil, which involved 120 patients of both sexes were analyzed with a diagnosis of hypertension and 120 patients without a diagnosis of hypertension. The audiological function was assessed by tonal and vocal audiometry. The quality of life was defines by the MINICHAL BRASIL questionnaire. Results: The prevalence of hearing loss was high in both groups (82.5 % and 75.8 %, in hypertension group and control, respectively, p=0.003). The sensorineural was the most common type of hearing loss (48.5 %) in hypertension group while conductive hearing loss was predominant (61.5 %) in the control group. There were no difference in the intensity of hearing loss between the groups (p=0,21). The main hearing complaint was hearing loss (51 %), followed by ear pain (14 %). There was worse quality of life in hypertensive individuals with hearing loss (p= 0.0001). Conclusion: Hypertensive individuals showed higher prevalence of auditory events, including hearing loss, sensorineural hearing loss is predominant . Hearing loss is associated with worse quality of life of hypertensive individuals even when these pressure values are within normal limits

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

O processo de reprodução humana é caracterizado por experiências singulares que afetam o homem e a mulher de forma diferenciada. O homem que vivencia o processo gestatório de sua companheira, mesmo não sofrendo as modificações gravídicas, enfrenta transformações relacionadas ao papel que desempenha junto à mulher gestante. Tal vivência é entremeada por significados diversos que dependem tanto da forma como ele concebe a gestação de sua companheira, como da experiência com gestações anteriores. Sendo assim, torna-se imprescindível reconhecer as concepções masculinas acerca das repercussões que uma gravidez conduz nas experiências seguintes, a fim de promover uma atenção em saúde direcionada para as necessidades apresentadas pelo homem, favorecer seu envolvimento e responsabilização no processo gestatório de sua companheira. Com base no exposto, objetivou-se compreender a concepção de homens, que vivenciam a gestação de sua companheira, acerca da influência de uma gravidez anterior sobre as demais. Para tal foi realizado uma pesquisa qualitativa por meio de entrevista semi-estruturada com homens que vivenciaram duas ou mais gestações de sua companheira com intervalo de no máximo cinco anos entre tais experiências. Cumpre ressaltar que as entrevistas ocorreram após parecer favorável de no 045/2011, emitido pelo Comitê de Ética e Pesquisa da Universidade Federal do Rio Grande do Norte. Os dados foram coletados por amostragem teórica e analisados, seguindo as etapas da Teoria Fundamentada nos Dados, sob a ótica proposta pelo Interacionismo Simbólico. Seguindo o percurso dos referenciais adotados, foram elaboradas três categorias: Sentimentos vivenciados pelo homem diante da gestação da companheira, Expectativas do homem diante da gestação da companheira e Repercussões da vivência de uma gravidez anterior sobre a seguinte. A análise das propriedades e dimensões de tais categorias suscitou à construção da teoria Influências de uma gravidez sobre a outra. Assim evidenciou-se que a gravidez anterior influencia nos sentimentos do homem diante de uma nova gestação, nas suas expectativas, principalmente quanto ao sexo do segundo filho, bem como em suas atitudes e comportamentos diante da companheira, do primogênito e do recém-nascido. Revelou-se que em todos esses aspectos ocorreram processos interativos do homem consigo mesmo, com sua companheira e com o contexto social no qual estava inserido. Assim sendo, conclui-se que a interação que o homem estabelece com a experiência anterior conduz a determinação de seus sentimentos e ações frente ao advento de uma nova gravidez. Diante disso, compreende-se que o entendimento sobre tal assunto é imprescindível para fundamentar ações do enfermeiro voltadas à inserção do homem no processo de gravidez, por meio da compreensão das repercussões de vivências anteriores na sua experiência com as demais gestações. Essa compreensão possibilitará uma dinâmica familiar favorável à adaptações requeridas em processos gestatórios seguintes, centrada na satisfação e valorização de seus membros.
