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

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 present work treats the movements dedicated to reinvidication per land and social rights for the field works, among 1960 and 1964. Trying to understand this question in the Rio Grande do Norte it is necessary to consider the connection between the catholic church and the rural syndicates besides the influence of the Brazilian communist party, and still other social movements and the state. The structures politics local, national and international, had considerable importance to the organization rural potiguares workers. The rural potiguares syndicate appear in 1961 - after a hard organization work starting of the Service of Rural Assistance - and expand itself through state until the middle of 1962. Soon the first big conflicts an important manifestation are perceive, indirectly referring to a increasing movement's performance. The Favoring Progresses chains co quested a biggest influence in the politics destiny of the Rio Grande do Norte, in front of integration among syndicates, educational projects, and favoring progress's politics. But the military coup hired that the hope overflow the field

The birth models of care are discussed, in the light of classical and contemporary social science theoretical background, emphasizing the humanistic model. The double spiral of the sociology of absences and the sociology of emergences is detailed, being based, on one hand, on the translation of experiences of knowledge, and, on the other, on the translation of experiences of information and communication, by revealing the movement articulated by Brazilian women on blogs that defend and bring into light initiatives aiming to recover natural and humanized birth. A cartography of the thematic ideas in birth literature is produced, resulting in the elaboration of a synthetic map on obstetric models of care in contemporaneity, pointing out the consequences of the obstetric model that has become hegemonic in contemporary societies, and comparing that model to others that work more efficaciously to mothers and babies. A symbolic cartography of the activism for humanizing birth on the Brazilian blogosphere is configured by the elaboration of an analytical map synthetizing the main mottos defended by the movement: Normal humanized birth; Against obstetrical violence; and Planned home birth. The superposition of the obstetric models of care s map and the rebirth of birth s analytical map indicates it is necessary to reinforce three main measures in order to make a paradigmatic turn in contemporary birth models of care possible: pave the way for the humanistic care of assistance in normal birth, by defending and highlighting practices and professionals that act in compliance with evidence based medicine, respecting the physiology of birth; denaturalize obstetric violence, by showing how routine procedures and interventions can be means of aggression, jeopardizing the autonomy, the protagonism and the respect towards women; and motivate initiatives of planned home birth, the best place for the occurrence of holistic experiences of birth. It is concluded that Internet tools have allowed a pioneer mobilization in respecting women s reproductive rights in Brazil and that the potential of the crowd s biopower that resides on the blogosphere can turn blogs into a hegemonic alternative way to reach more democratic forms of social organization. In that condition of being virtually hegemonic in contesting the established power, these blogs can be understood, therefore, as potentially great contra-hegemonic channels for the rebirth of birth and for the reinvention of social emancipation, as their author s articulate and organize themselves to strive against the waste of experience, trying to create reciprocal intelligibility amongst different experiences of world

O sangue do cordão umbilical humano tem sido crescentemente utilizado como fonte de células-tronco. Os modelos experimentais de células-tronco da medula óssea, em cães, têm propiciado informações importantes para transplantes medulares em humanos. Vários trabalhos citam a influência do tipo de parto nas características do sangue do cordão umbilical (SCU) humano. Entretanto, não existem relatos sobre a colheita do sangue do cordão umbilical de cães. O objetivo deste ensaio é avaliar a influência do tipo de parto na hematologia do cordão umbilical de cães. No presente protocolo experimental, foram estudados 54 fetos de cães, ao final da vida intra-uterina, provenientes de parto normal (n=24) e cesariana (n=30). A colheita de sangue do cordão umbilical foi realizada com seringa de cinco mL contendo solução anticoagulante EDTA (1mg/1mL sangue). em seguida, a contagem global de hemácias, leucócitos, plaquetas, a determinação da concentração de hemoglobina, taxa de hematócrito, os índices eritrocitários foram realizados no contador automático de células. A contagem diferencial de leucócitos foi determinada em esfregaços de SCU corados com May-Grunwald-Giemsa (MGG). Com relação ao eritrograma e ao plaquetograma, não houve diferença significativa entre as amostras obtidas em cesarianas e partos normais. Os valores do leucograma do SCU colhido em partos normais foram superiores àqueles obtidos em cesarianas (P<0,05). Portanto, o tipo de parto influencia os valores hematológicos do cordão umbilical de cães.

The humanization of the birth process is a current health policy priority. Within that perspective, the presence of a partner during the birth is a benefit guaranteed by the Law 111008/05. The purpose of this study is to comprehend the woman s experience with the presence of a birth partner as a legal right. It is a qualitative descriptive study based on Symbolic Interactionism and conducted using the grounded theory methodology. Data were collected by semi-structured interviews conducted during August to December 2006, with women that had the presence of a partner during their birth experience and that were in the first 24 hours of puerperium. Data analysis resulted in the identification of the phenomena: FEELING GOOD, RECOGNIZING THE BOND WITH THE PARTNER, RECOGNIZING THE IMPORTANCE OF THE EXPERIENCE and NOT KNOWING THE RIGHT. These enabled the identification of the central phenomenon LIVING THE WELL-BEING IN THE UNKNOWN. The study demonstrated that the birth experience with the presence of partner is a positive one, resulting in benefits such as tranquility, support, and assurance, which, in that context, signify well-being. However, the women do not visualize the experience as a right, therefore remaining alienated from their civic practice. The understanding of the experience was enabled by the conceptual construction obtained from the categories of the interactions between the women and their birth partners during the event. The explanation of the phenomenon LIVING THE WELL-BEING IN THE UNKNOWN reflects the theoretical structure obtained from the integration of the identified concepts. The study points out the need for health professionals to improve the information given to women during the birth process and to work the civic duties of the women in reproductive health

The effect of environmental and genetic effects on the farrowing interval in Dalland (C-40) sows in the Southeast of Brazil was studied. Data consisting of 1,013 farrowing intervals recorded in two herds were analyzed, using a model that included the sire and the dam as random effects and the year of farrowing, the herd and the farrowing season as fixed effects, plus the covariables sow's age at farrowing, litter size at birth, lactation length and weaning-estrus interval. For the farrowing interval first only, variance components were estimated by REML, with an animal model that included, as fixed effect, a contemporary group and, as random effects, the additive genetic variance and the error. The mean farrowing interval was 140.9+5.7 days, with a 4.0% coefficient of variation. Variance analysis showed no effect of either year, season of farrowing or herd on the farrowing interval. The sire effect was not important for the farrowing interval, but the dam represented an important source of variation. The total number of piglets born and the sow's age at farrowing had no influence on the farrowing interval. The length of lactation exerted an influence on the farrowing interval, accounting for 19.4% of the total variation of this trait. Likewise, the linear regression of the weaning-estrus interval in relation to the farrowing interval was highly significant, accounting for 51.7% of the total variation. The heritability estimate was 0.00, suggesting that no genetic gain can be obtained by selection for a shorter farrowing interval.

Neste estudo, após a edição dos dados, foram utilizadas 87.372 informações de escores visuais de conformação (C), precocidade (P) e musculatura (M) à desmama de animais Nelore, provenientes de rebanhos comerciais. Os objetivos, neste trabalho, foram estudar os efeitos da idade da vaca ao parto (IDV), data Juliana de nascimento (DJN) e idade à desmama (ID) sobre C, P e M e estimar os fatores de correção para os mesmos. Os modelos utilizados incluíram os efeitos fixos de grupo contemporâneo (rebanho, retiro, ano e mês de nascimento, sexo e grupo de manejo ao nascimento e à desmama) e, como covariáveis, os efeitos de idade da vaca (para cada sexo do bezerro), de data juliana de nascimento e da idade do bezerro à desmama. Para a idade da vaca, usou-se um polinômio segmentado quadrático-quadrático. Para a data juliana de nascimento, foi utilizado um polinômio segmentado com três segmentos quadráticos, enquanto, para a idade do bezerro à desmama, foi empregado um polinômio ordinário quadrático. Todos os efeitos considerados no modelo influenciaram significativamente os escores visuais. A simples inclusão da estação ou do mês de nascimento no grupo contemporâneo não foi suficiente para corrigir diferenças em escores decorrentes do efeito da data de nascimento. Para avaliação genética dos animais para escores visuais à desmama, os mesmos devem ser ajustados para idade da vaca ao parto, data juliana de nascimento e idade do bezerro à desmama.

Foram estimadas as correlações genéticas entre características de produção de leite (produção de leite, gordura, proteína e duração da lactação em até 305 dias, na primeira lactação), características de peso (taxa de crescimento de novilhas entre 12-24 meses e peso médio de vacas) e idade ao primeiro parto, em uma população de fêmeas Mestiço Leiteiro Brasileiro (MLB), por meio de metodologia REML, sob modelo animal. As estimativas de herdabilidade das características estudadas na ordem acima foram, respectivamente, 0,28± 0,08, 0,30±0,11, 0,28±0,09, 0,19±0,07, 0,18±0,06, 0,42±0,10 e 0,48±0,12. As correlações genéticas entre peso médio da vaca e a produção de leite, gordura e proteína foram, respectivamente, -0,22±0,22, -0,49±0,31 e -0,22±0,23 e da taxa de crescimento das novilhas com a produção de leite, gordura e proteína foram respectivamente, -0,59±0,35, -0,73±0,44 e -0,62±0,37. As correlações genéticas entre produção de leite, peso médio das vacas e taxa de crescimento das novilhas com idade ao primeiro parto foram respectivamente, 0,05±0,18, -0,05±0,18 e 0,02±0,20. A alta correlação genética (0,93±0,02) entre produção de leite e duração da lactação indicou que não se deve remover a variação na duração da lactação na seleção de gado leiteiro tropical.

Estimou-se a herdabilidade da idade ao primeiro parto (IPP) a partir de quatro conjuntos com diferentes tipos de informação. A primeira estimativa (IPP1) foi realizada com as novilhas (n= 6.222) expostas apenas na estação normal, ou seja, aos 24 meses de idade. No segundo conjunto (IPP2), fizeram parte do arquivo todas as fêmeas (n= 15.746) com informação da IPP. No terceiro (IPP3), estimou-se a herdabilidade de um grupo mais restrito de novilhas (n= 9.524), as quais tiveram manejo diferenciado na fazenda; todas as fêmeas pertencentes a este grupo foram expostas mais cedo à reprodução, aproximadamente 18 meses de idade (estação de monta antecipada). Para o quarto grupo (IPP4), usou-se o arquivo completo de dados, ou seja, os registros de todas as fêmeas nascidas no rebanho (n= 40.954). Foram considerados no modelo o efeito aleatório de animal e os efeitos fixos de grupo contemporâneo e os efeitos linear e quadrático de idade da mãe ao parto. As herdabilidades estimadas para IPP1, IPP2, IPP3 e IPP4 foram, respectivamente, 0,00; 0,11; 0,20 e 0,36.

Estimaram-se parâmetros genéticos para idade ao primeiro parto (IPP) de, aproximadamente, 6.000 novilhas, utilizando-se três diferentes definições de grupo contemporâneo (GC). Foram considerados no modelo o efeito aleatório de animal e os efeitos fixos de GC, além dos efeitos linear e quadrático da idade da mãe da novilha ao parto (IDV). A primeira definição de grupo contemporâneo (GC1) considerou as variáveis fazenda, ano, estação de nascimento, grupo de manejo de nascimento, desmama e sobreano e tipo de serviço (monta natural, monta controlada ou inseminação artificial). A segunda definição de grupo contemporâneo (GC2) incluiu as mesmas variáveis de GC1, além de ano e estação do parto. A terceira definição de grupo contemporâneo considerou as variáveis ano e estação de nascimento, fazenda, ano e estação do parto e tipo de cobertura. As estimativas de herdabilidade para IPP foram de 0,16 ± 0,03, 0,09 ± 0,03 e 0,11 ± 0,02, considerando-se GC1, GC2 e GC3, respectivamente.

Foram utilizadas 30 vacas da raça Guzerá (10 por tratamento), suplementadas no pré-parto (PRE), pós-parto (POS) e sem suplementação (SS) com os objetivos de avaliar no pós-parto as variações do peso corporal (PC), do escore de condição corporal (ECC) (1 = muito magra a 9 = muito gorda) e dos níveis plasmáticos de colesterol total (NPCT), o índice de prenhez (IP) até 112 dias pós-parto e a viabilidade econômica dos tratamentos PRE e POS, que constou de 1 kg/dia/animal de concentrado (16% PB; 3000 kcal ED/kg). O PC e o ECC foram obtidos a cada 28 dias, e colheitas de sangue semanalmente para análise dos NPCT até 112 dias pós-parto. O PC e o ECC tiveram interação dias pós-parto x tratamento. O tratamento PRE aumentou o PC e o ECC das vacas ao parto: 477,80 kg e 6,20 respectivamente, em comparação com os tratamentos POS e SS de 453,37 kg e 5,5; 447,57 kg e 5,28, respectivamente. O PC e o ECC do tratamento PRE foi superior de 28 a 84 dias comparado ao SS, enquanto o tratamento POS foi superior apenas de 84 a 112 dias pós-parto. O tratamento POS não diferiu do PRE no PC de 56 a 112 dias pós-parto e no ECC de 28 a 112 dias pós-parto. O tratamento POS proporcionou aumento do PC e ECC das vacas, já os tratamentos PRE e SS perderam PC e ECC até 112 dias pós-parto. O PC e ECC dos tratamentos PRE, POS e SS aos 112 dias pós-parto foram de 457,79 kg e 5,38; 461,87 kg e 5,66; 436,57 kg e 4,78, respectivamente. Os NPCT tiveram efeito dos dias pós-parto, mas não de tratamento, aumentando com os dias pós-parto. Os IP não foram influenciados pelos tratamentos PRE, POS e SS com 50,00; 62,20 e 57,14%, respectivamente. Economicamente a suplementação não foi viável.
