Background Studies of maternal mortality have been shown to result in important improvements to women’s health. It is now recognised that in countries such as the UK, where maternal deaths are rare, the study of near-miss severe maternal morbidity provides additional information to aid disease prevention, treatment and service provision. Objectives To (1) estimate the incidence of specific near-miss morbidities; (2) assess the contribution of existing risk factors to incidence; (3) describe different interventions and their impact on outcomes and costs; (4) identify any groups in which outcomes differ; (5) investigate factors associated with maternal death; (6) compare an external confidential enquiry or a local review approach for investigating quality of care for affected women; and (7) assess the longer-term impacts. Methods Mixed quantitative and qualitative methods including primary national observational studies, database analyses, surveys and case studies overseen by a user advisory group. Setting Maternity units in all four countries of the UK. Participants Women with near-miss maternal morbidities, their partners and comparison women without severe morbidity. Main outcome measures The incidence, risk factors, management and outcomes of uterine rupture, placenta accreta, haemolysis, elevated liver enzymes and low platelets (HELLP) syndrome, severe sepsis, amniotic fluid embolism and pregnancy at advanced maternal age (≥ 48 years at completion of pregnancy); factors associated with progression from severe morbidity to death; associations between severe maternal morbidity and ethnicity and socioeconomic status; lessons for care identified by local and external review; economic evaluation of interventions for management of postpartum haemorrhage (PPH); women’s experiences of near-miss maternal morbidity; long-term outcomes; and models of maternity care commissioned through experience-led and standard approaches. Results Women and their partners reported long-term impacts of near-miss maternal morbidities on their physical and mental health. Older maternal age and caesarean delivery are associated with severe maternal morbidity in both current and future pregnancies. Antibiotic prescription for pregnant or postpartum women with suspected infection does not necessarily prevent progression to severe sepsis, which may be rapidly progressive. Delay in delivery, of up to 48 hours, may be safely undertaken in women with HELLP syndrome in whom there is no fetal compromise. Uterine compression sutures are a cost-effective second-line therapy for PPH. Medical comorbidities are associated with a fivefold increase in the odds of maternal death from direct pregnancy complications. External reviews identified more specific clinical messages for care than local reviews. Experience-led commissioning may be used as a way to commission maternity services. Limitations This programme used observational studies, some with limited sample size, and the possibility of uncontrolled confounding cannot be excluded. Conclusions Implementation of the findings of this research could prevent both future severe pregnancy complications as well as improving the outcome of pregnancy for women. One of the clearest findings relates to the population of women with other medical and mental health problems in pregnancy and their risk of severe morbidity. Further research into models of pre-pregnancy, pregnancy and postnatal care is clearly needed.

Cardiomyopathy in Offspring of Pregestational Diabetic Mouse Pregnancy

PURPOSE: To investigate cardiomyopathy in offspring in a mouse model of pregestational type 1 diabetic pregnancy.

METHODS: Pregestational diabetes was induced with STZ administration in female C57BL6/J mice that were subsequently mated with healthy C57BL6/J males. Offspring were sacrificed at embryonic day 18.5 and 6-week adolescent and 12-week adult stages. The size and number of cardiomyocyte nuclei and also the extent of collagen deposition within the hearts of diabetic and control offspring were assessed following cardiac tissue staining with either haematoxylin and eosin or Picrosirius red and subsequently quantified using automated digital image analysis.

RESULTS: Offspring from diabetic mice at embryonic day 18.5 had a significantly higher number of cardiomyocyte nuclei present compared to controls. These nuclei were also significantly smaller than controls. Collagen deposition was shown to be significantly increased in the hearts of diabetic offspring at the same age. No significant differences were found between the groups at 6 and 12 weeks.

CONCLUSIONS: Our results from offspring of type 1 diabetic mice show increased myocardial collagen deposition in late gestation and have increased myocardial nuclear counts (hyperplasia) as opposed to increased myocardial nuclear size (hypertrophy) in late gestation. These changes normalize postpartum after removal from the maternal intrauterine environment.

Proposta de processo de enfermagem em unidade de internação obstétrica: históricos, diagnósticos e cuidados de enfermagem à luz de horta fundamentada em nanda

O presente estudo teve como objetivo geral elaborar uma proposta de processo de enfermagem contemplando históricos de enfermagem, diagnósticos de enfermagem, prescrição de cuidados de enfermagem para gestantes e puérperas em Unidade de Internação Obstétrica à luz de Horta, fundamentada em NANDA e, como objetivos específicos: identificar os dados clínico-obstétricos mais frequentes das gestantes em Unidade de Internação Obstétrica; identificar os dados clínico-obstétricos mais frequentes das puérperas em Unidade de Internação Obstétrica; identificar os diagnósticos de enfermagem a partir dos dados clínico-obstétricos mais frequentes das gestantes em Unidade de Internação Obstétrica; identificar os diagnósticos de enfermagem a partir dos dados clínico-obstétricos mais frequentes das puérperas em Unidade de Internação Obstétrica; elaborar modelos de histórico de enfermagem e de prescrição de cuidados de enfermagem para os diagnósticos de enfermagem identificados; e obter o consenso dos enfermeiros assistenciais da Unidade de Internação Obstétrica sobre a proposta construída. Trata-se de pesquisa qualitativa, descritiva e exploratória, realizada em uma Unidade de Internação Obstétrica de um hospital universitário do Sul do Brasil. Realizou-se uma consulta documental em 148 prontuários, com vistas à identificação dos diagnósticos e cuidados de enfermagem, baseados, respectivamente, na taxonomia II da North American Diagnosis Association 2009-2011 e da Nursing Intervention Classification. Desenvolveu-se um modelo de histórico de enfermagem para gestante/puérpera e outro para o recém-nascido. No total, identificaram-se 26 diagnósticos de enfermagem, assim distribuídos: nove direcionados às gestantes; nove, às puérperas; dois, ao binômio mãe/filho; seis, ao recém-nascido. A análise foi realizada por meio da apresentação da proposta construída e discussão com base em autores da área. Com isso, almeja-se contribuir para direcionar o cuidado de enfermagem às necessidades das gestantes, puérperas, binômios mãe/filho e recém-nascidos nesse microcenário, favorecendo a educação em saúde, a identificação precoce e a prevenção de complicações. Permanecem lacunas quanto às necessidades psicoespirituais, visto que elas não foram abordadas nos resultados. Assim, essa proposta de Processo de Enfermagem em Unidade Obstétrica contemplando históricos, diagnósticos e cuidados de enfermagem mantém em aberto o aperfeiçoamento do modelo, visando à inclusão de outros diagnósticos de enfermagem, de forma a aproximar-se de um cuidado mais holístico.

Assessments of body composition and bone parameters of lactating rats treated with diet containing flaxseed meal (Linum usitatissinum) during post-weaning period

Introduction: There are few studies on body composition and the effects of diet on weight postpartum women. The aim was to evaluate the body composition and bone parameters in lactating rats treated with diet containing flaxseed flour during postweaning period. Methods: After weaning, the lactating rat were divided in control (n = 6) and experimental (F, n = 6) group, treated with 25% flaxseed flour diet. After 30 days, body composition by dual-energy X-ray absorptiometry, serum analysis, organs and intra-abdominal fat mass, femur and lumbar vertebra parameters were determined. Results: The groups showed similar food intake, body mass and bone parameters. While F group showed the following: lower body (-5%), gonadal (-17%), mesenteric (-23%) and intra-abdominal (-6%) fat mass. Increase of HDL-cholesterol (+10%) and lower glucose (-15%), triglycerides (P < 0.05, -37%) and cholesterol (P < 0.05, -21%). Conclusions: The findings highlight the effects of flaxseed for control of adiposity and to maintain a healthy biochemical profile during the postnatal period.

Interaction between mercury (Hg), arsenic (As) and selenium (Se) affects the activity of glutathione S-transferase in breast milk: possible relationship with fish and shellfish intake

Breast milk is regarded as an ideal source of nutrients for the growth and development of neonates, but it can also be a potential source of pollutants. Mothers can be exposed to different contaminants as a result of their lifestyle and environmental pollution. Mercury (Hg) and arsenic (As) could adversely affect the development of fetal and neonatal nervous system. Some fish and shellfish are rich in selenium (Se), an essential trace element that forms part of several enzymes related to the detoxification process, including glutathione S-transferase (GST). The goal of this study was to determine the interaction between Hg, As and Se and analyze its effect on the activity of GST in breast milk. Milk samples were collected from women between day 7 and 10 postpartum. The GST activity was determined spectrophotometrically; total Hg, As and Se concentrations were measured by atomic absorption spectrometry. To explain the possible association of Hg, As and Se concentrations with GST activity in breast milk, generalized linear models were constructed. The model explained 44% of the GST activity measured in breast milk. The GLM suggests that GST activity was positively correlated with Hg, As and Se concentrations. The activity of the enzyme was also explained by the frequency of consumption of marine fish and shellfish in the diet of the breastfeeding women.

Pregnancy after uterine artery embolization: a case report in a woman with leiomyomata

Background. Several pregnancies have been reported after embolization of uterine artery. This procedure is an accepted nonsurgical treatment for symptomatic uterine fibroids but its safety in women desiring future childbearing is not well established. Case Report. We present a 40-year-old woman with leiomyomata who became pregnant after previously undergone uterine artery embolization for three times. The placenta was previa and the fetus was in transverse position. She had a cesarean delivery of an appropriately grown fetus at 37 weeks, which was followed by uterine atony requiring hysterectomy. Conclusion. Although pregnancy-related outcomes remain understudied, the available reports evidence that pregnancies after uterine artery embolization may be at significantly increased risk for postpartum hemorrhage, cesarean delivery, abnormal placentation, and malpresentation. In patients who are undergoing this type of treatment and contemplating pregnancy, the possibility of adverse complications should be taken in consideration and women should be appropriately advised.

ADVANCES AND CHALLENGES OF BREASTFEEDING IN BRAZIL: AN INTEGRATIVE REVIEW

Objective: To analyze the panorama of breastfeeding in Brazil through an integrative literature review highlighting its advances and challenges. Methods: We carried out an integrative literature review in the SciELO and PubMed databases and in booklets published on the websites of the Ministry of Health and the International Baby Food Action Network (IFBAN) using the following Portuguese and English descriptors: aleitamento materno (breastfeeding), autoeficácia (self-efficacy), promoção da saúde (health promotion) and desmame (weaning) in the period from 2002 to 2015. Results: We identified at first 43 articles, 33 booklets, 1 thesis and 3 dissertations, including in the study 17 articles, 3 dissertations and 19 booklets due to information saturation. It was verified that breastfeeding rates have reduced significantly over time with direct implications in infant mortality rates, being associated with early weaning and the lack of promotion of maternal self-efficacy in the prenatal and postpartum. To change this situation, Brazil imposed a number of public policies aimed at breastfeeding success, which advocated to raise rates. Conclusion: Despite the advances, the Brazilian panorama of breastfeeding shows that the country remains below the recommendations of international organizations, and overcoming the obstacles to successful breastfeeding constitutes a major challenge for the Brazilian public health.

Acute Acalculous Cholecystitis as a Presenting Manifestation in Systemic Lupus Erythematosus

Systemic lupus erythematosus (SLE) is known to involve the gastrointestinal tract, but gallbladder involvement is rare. The authors report the case of a 26-year-old postpartum female who presented with acute right upper quadrant abdominal pain and was diagnosed with acute acalculous cholecystitis (AAC). In the presence of concomitant features of nephritis, pericardial effusion, anaemia and positive ANA titre, the diagnosis of SLE was confirmed during hospitalisation. Histopathological analysis of the gall bladder revealed evidence of vasculitis. Although rare, AAC can be the first presentation of patients diagnosed with SLE. Prompt diagnosis and management results in a better patient outcome.

A prática baseada na evidência : a amamentação como fator preventivo da depressão pós-parto

Enquadramento: É expectável que o pós-parto seja um período de alegria. Todavia, nem sempre é assim, já que pode ser um período marcado por momentos de tristeza, cansaço e desânimo. Reconhecendo as vantagens da amamentação para a saúde e bem-estar do recémnascido e da mãe, acreditamos que esta possa ser preventiva da depressão pós-parto. Objetivos: Obter a melhor evidência científica para compreender se a amamentação tem efeito preventivo na depressão pós-parto. Método: Foi efetuada uma revisão integrativa da literatura sobre a relação entre a amamentação e a depressão pós-parto através das bases de dados: EBSCO host, LILACS, PubMed, SciELO, Repositórios institucionais e Google Académico. Selecionaram-se quinze artigos que obedeceram aos critérios de inclusão deste estudo. Resultados: A maioria dos estudos identifica a amamentação como sendo preventiva da depressão pós-parto, destacando a importância da amamentação para a saúde mental da puérpera e consequentemente para a diminuição das hipóteses de desenvolver depressão pósparto. Cinco artigos identificam-na também como sendo um fator de risco e um estudo não encontrou uma associação clara entre a amamentação e a depressão pós-parto. Conclusões: São descritos vários benefícios da amamentação, os quais terão um efeito preventivo contra a depressão pós-parto. Uma mulher informada e apoiada acerca da amamentação será capaz de se sentir confiante no seu novo papel. É essencial um investimento constante por parte da equipa de saúde, iniciado durante o processo do planeamento do casal para a gravidez, e mantendo-se ao longo da gravidez, parto e pós-parto. Palavras-chave: “Amamentação”, “depressão pós-parto”, “prevenção”.

Immune function, gene expression, blood indices and performance in transition dairy cows affected by diet and inflammation

The transition period is associated with the peak incidence of production problems, metabolic disorders and infectious diseases in dairy cows (Drackley, 1999). During this time the cow’s immune system seems to be weakened; it is apparent that metabolic challenges associated with the onset of lactation are factors capable of affecting immune function. However, the reasons for this state are not entirely clear (Goff, 2006). The negative energy balance associated with parturition leads to extensive mobilization of fatty acids stored in adipose tissue, thus, causing marked elevations in blood non-esterified fatty acids (NEFA) and B-hydroxybutyrate (BHBA) concentrations (Drackley et al., 2001). Prepartal level of dietary energy can potentially affect adipose tissue deposition and, thus, the amount of NEFA released into blood and available for metabolism in liver (Drackley et al., 2005). The current feeding practices for pregnant non-lactating cows has been called into question because increasing amounts of moderate-to-high energy diets (i.e. those more similar to lactation diets in the content of energy) during the last 3 wk postpartum have largely failed to overcome peripartal health problems, excessive body condition loss after calving, or declining fertility (Beever, 2006). Current prepartal feeding practices can lead to elevated intakes of energy, which can increase fat deposition in the viscera and upon parturition lead to compromised liver metabolism (Beever, 2006, Drackley et al., 2005). Our general hypothesis was that overfeeding dietary energy during the dry period, accompanied by the metabolic challenges associated with the onset of lactation would render the cow’s immune function less responsive early postpartum. The chapters in this dissertation evaluated neutrophil function, metabolic and inflammation indices and gene expression affected by the plane of dietary energy prepartum and an early post-partum inflammatory challenge in dairy cows. The diet effect in this experiment was transcendental during the transition period and potentially during the entire lactation. Changes in energy balance were observed and provided a good model to study the challenges associated with the onset of lactation. Overall the LPS model provided a consistent response representing an inflammation incident; however the changes in metabolic indices were sudden and hard to detect in most of the cases during the days following the challenge. In general overfeeding dietary energy during the dry period resulted in a less responsive immune function during the early postpartum. In other words, controlling the dietary energy prepartum has more benefits for the dairy cow during transition.

Influência do estado nutricional materno em vitamina A sobre os níveis de imunoglobulina A no colostro humano

Mothers with good vitamin A nutritional status during gestation and lactation are better able to nourish and protect their infant with maternal milk. Our hypothesis is that women with more serum retinol have more retinol and secretory immunoglobulin A in colostrum. 190 healthy puerperal women from a Brazilian public maternity were recruited and divided according to the cutoff point for serum retinol (30 μg/dL). A number of the women was supplemented with 200000 UI (60 mg) of retinyl palmitate in the immediate postpartum. Serum and colostrum were collected on the 1st day postpartum and colostrum again on the following day. Retinol (serum and colostrum) was analyzed by HPLC and SIgA (colostrum) by turbidimetry. The mothers presented with adequate biochemical indicators of nutritional status, according to serum retinol (44.6 μg/dL). There were significant differences (p= 0.0017 and p= 0.043, respectively) in retinol and SIgA levels in the colostrum of mothers with serum retinol > 30 μg/dL and < 30 μg/dL. The concentration of SIgA in the colostrum of non-supplemented mothers on the 1st day postpartum was 822.6 mg/dL, decreasing after 24 hours to 343.7 mg/dL. Supplemented mothers showed levels of SIgA in colostrum of 498.9 mg/dL on the 2nd day postpartum (p= 0.00006). The colostrum of women with good vitamin A nutritional status had more retinol and SIgA. Additionally, maternal supplementation increases the levels of SIgA in colostrum. The higher levels of SIgA on the 1st day postpartum showed the importance of early breastfeeding, given that it provides considerable immunological benefits to newborn infants
