Metabolic alterations in pregnant women: gestational diabetes

Gestational diabetes mellitus (GDM) and controversy are old friends. The impact of GDM on maternal and fetal health has been increasingly recognized. Nevertheless, universal consensus on the diagnostic methods and thresholds has long been lacking. Published guidelines from major societies differ significantly from one another, with recommendations ranging from aggressive screening to no routine screening at all. As a result, real-world practice is equally varied. This article recaps the latest evidence-based recommendations for the diagnosis and classification of GDM. It reviews the current evidence base for intensive multidisciplinary treatment of GDM and provides recommendations for postpartum management to delay and/or prevent progression to type 2 diabetes.

Temporal evolution and spatial distribution of maternal death

OBJECTIVE To analyze the temporal evolution of maternal mortality and its spatial distribution.METHODS Ecological study with a sample made up of 845 maternal deaths in women between 10 and 49 years, registered from 1999 to 2008 in the state of Rio Grande do Sul, Southern Brazil. Data were obtained from Information System on Mortality of Ministry of Health. The maternal mortality ratio and the specific maternal mortality ratio were calculated from records, and analyzed by the Poisson regression model. In the spatial distribution, three maps of the state were built with the rates in the geographical macro-regions, in 1999, 2003, and 2008.RESULTS There was an increase of 2.0% in the period of ten years (95%CI 1.00;1.04; p = 0.01), with no significant change in the magnitude of the maternal mortality ratio. The Serra macro-region presented the highest maternal mortality ratio (1.15, 95%CI 1.08;1.21; p < 0.001). Most deaths in Rio Grande do Sul were of white women over 40 years, with a lower level of education. The time of delivery/abortion and postpartum are times of increased maternal risk, with a greater negative impact of direct causes such as hypertension and bleeding.CONCLUSIONS The lack of improvement in maternal mortality ratio indicates that public policies had no impact on women’s reproductive and maternal health. It is needed to qualify the attention to women’s health, especially in the prenatal period, seeking to identify and prevent risk factors, as a strategy of reducing maternal death.

Factors associated to breastfeeding in the first hour of life: systematic review

OBJECTIVE To identify independent risk factors for non-breastfeeding within the first hour of life.METHODS A systematic review of Medline, LILACS, Scopus, and Web of Science electronic databases, till August 30, 2013, was performed without restrictions on language or date of publishing. Studies that used regression models and provided adjusted measures of association were included. Studies in which the regression model was not specified or those based on specific populations regarding age or the presence of morbidities were excluded.RESULTS The search resulted in 155 articles, from which 18 met the inclusion criteria. These were conducted in Asia (9), Africa (5), and South America (4), between 1999 and 2013. The prevalence of breastfeeding within the first hour of life ranged from 11.4%, in a province of Saudi Arabia, to 83.3% in Sri Lanka. Cesarean delivery was the most consistent risk factor for non-breastfeeding within the first hour of life. “Low family income”, “maternal age less than 25 years”, “low maternal education”, “no prenatal visit”, “home delivery”, “no prenatal guidance on breastfeeding” and “preterm birth” were reported as risk factors in at least two studies.CONCLUSIONS Besides the hospital routines, indicators for low socioeconomic status and poor access to health services were also identified as independent risk factors for non-breastfeeding within the first hour of life. Policies to promote breastfeeding, appropriate to each context, should aim to reduce inequalities in health.

Prevalence of syphilis in pregnancy and prenatal syphilis testing in Brazil: Birth in Brazil study

OBJECTIVE Determine the coverage rate of syphilis testing during prenatal care and the prevalence of syphilis in pregnant women in Brazil. METHODS This is a national hospital-based cohort study conducted in Brazil with 23,894 postpartum women between 2011 and 2012. Data were obtained using interviews with postpartum women, hospital records, and prenatal care cards. All postpartum women with a reactive serological test result recorded in the prenatal care card or syphilis diagnosis during hospitalization for childbirth were considered cases of syphilis in pregnancy. The Chi-square test was used for determining the disease prevalence and testing coverage rate by region of residence, self-reported skin color, maternal age, and type of prenatal and child delivery care units. RESULTS Prenatal care covered 98.7% postpartum women. Syphilis testing coverage rate was 89.1% (one test) and 41.2% (two tests), and syphilis prevalence in pregnancy was 1.02% (95%CI 0.84;1.25). A lower prenatal coverage rate was observed among women in the North region, indigenous women, those with less education, and those who received prenatal care in public health care units. A lower testing coverage rate was observed among residents in the North, Northeast, and Midwest regions, among younger and non-white skin-color women, among those with lower education, and those who received prenatal care in public health care units. An increased prevalence of syphilis was observed among women with < 8 years of education (1.74%), who self-reported as black (1.8%) or mixed (1.2%), those who did not receive prenatal care (2.5%), and those attending public (1.37%) or mixed (0.93%) health care units. CONCLUSIONS The estimated prevalence of syphilis in pregnancy was similar to that reported in the last sentinel surveillance study conducted in 2006. There was an improvement in prenatal care and testing coverage rate, and the goals suggested by the World Health Organization were achieved in two regions. Regional and social inequalities in access to health care units, coupled with other gaps in health assistance, have led to the persistence of congenital syphilis as a major public health problem in Brazil.

Determinants of the exclusive breastfeeding abandonment: psychosocial factors

OBJECTIVE To assess the determinants of exclusive breastfeeding abandonment. METHODS Longitudinal study based on a birth cohort in Viçosa, MG, Southeastern Brazil. In 2011/2012, 168 new mothers accessing the public health network were followed. Three interviews, at 30, 60, and 120 days postpartum, with the new mothers were conducted. Exclusive breastfeeding abandonment was analyzed in the first, second, and fourth months after childbirth. The Edinburgh Postnatal Depression Scale was applied to identify depressive symptoms in the first and second meetings, with a score of ≥ 12 considered as the cutoff point. Socioeconomic, demographic, and obstetric variables were investigated, along with emotional conditions and the new mothers’ social network during pregnancy and the postpartum period. RESULTS The prevalence of exclusive breastfeeding abandonment at 30, 60, and 120 days postpartum was 53.6% (n = 90), 47.6% (n = 80), and 69.6% (n = 117), respectively, and its incidence in the fourth month compared with the first was 48.7%. Depressive symptoms and traumatic delivery were associated with exclusive breastfeeding abandonment in the second month after childbirth. In the fourth month, the following variables were significant: lower maternal education levels, lack of homeownership, returning to work, not receiving guidance on breastfeeding in the postpartum period, mother’s negative reaction to the news of pregnancy, and not receiving assistance from their partners for infant care. CONCLUSIONS Psychosocial and sociodemographic factors were strong predictors of early exclusive breastfeeding abandonment. Therefore, it is necessary to identify and provide early treatment to nursing mothers with depressive symptoms, decreasing the associated morbidity and promoting greater duration of exclusive breastfeeding. Support from health professionals, as well as that received at home and at work, can assist in this process.

Maternal mental health and nutritional status of six-month-old infants

ABSTRACT OBJECTIVE To analyze if maternal mental health is associated with infant nutritional status at six month of age. METHODS A cross-sectional study with 228 six-month-old infants who used primary health care units of the city of Rio de Janeiro, Southeastern Brazil. Mean weight-for-length and mean weight-for-age were expressed in z-scores considering the 2006 World Health Organization reference curves. Maternal mental health was measured by the 12-item General Health Questionnaire. The following cutoff points were used: ≥ 3 for common mental disorders, ≥ 5 for more severe mental disorders, and ≥ 9 for depression. The statistical analysis employed adjusted linear regression models. RESULTS The prevalence of common mental disorders, more severe mental disorders and depression was 39.9%, 23.7%, and 8.3%, respectively. Children of women with more severe mental disorders had, on average, a weight-for-length 0.37 z-scores lower than children of women without this health harm (p = 0.026). We also observed that the weight-for-length indicator of children of depressed mothers was, on average, 0.67 z-scores lower than that of children of nondepressed women (p = 0.010). Maternal depression was associated with lower mean values of weight-for-age z-scores (p = 0.041). CONCLUSIONS Maternal mental health is positively related to the inadequacy of the nutritional status of infants at six months.

Access to childbirth care by adolescents and young people in the Northeastern region of Brazil

ABSTRACT OBJECTIVE To identify the factors that interfere with the access of adolescents and young people to childbirth care for in the Northeast region of Brazil. METHODS Cross-sectional study with 3,014 adolescents and young people admitted to the selected maternity wards to give birth in the Northeast region of Brazil. The sample design was probabilistic, in two stages: the first corresponded to the health establishments and the second to women who had recently given birth and their babies. The data was collected by means of interviews and consulting the hospital records, from pre-tested electronic form. Descriptive statistics were used for the univariate analysis, Pearson’s Chi-square test for the bivariate analysis and multiple logistic regressions for the multivariate analysis. Sociodemographic variables, obstetrical history, and birth care were analyzed. RESULTS Half of the adolescents and young people interviewed had not been given guidance on the location that they should go to when in labor, and among those who had, 23.5% did not give birth in the indicated health service. Furthermore, one third (33.3%) had to travel in search of assisted birth, and the majority (66.7%) of the postpartum women came to maternity by their own means. In the bivariate analysis, the variables marital status, paid work, health insurance, number of previous pregnancies, parity, city location, and type of health establishment showed a significant association (p < 0.20) with inadequate access to childbirth care. The multivariate analysis showed that married adolescents and young people (p < 0.015), with no health insurance (p < 0.002) and from the countryside (p < 0.001) were more likely to have inadequate access to childbirth care. CONCLUSIONS Adolescents and young women, married, without health insurance, and from the countryside are more likely to have inadequate access to birth care. The articulation between outpatient care and birth care can improve this access and, consequently, minimize the maternal and fetal risks that arise from a lack of systematic hospitalization planning.

Seroprevalence of toxoplasmosis in Fortaleza, Ceará, Brazil

A serological survey of Toxoplasma gondii infection in population groups in Fortaleza, Brazil, was conducted, in order to identify seroprevalence rates according to age and risk factors associated with acquired infection. A Toxoplasma IgG-antibody enzyme immunoassay (Sanofi Pasteur Diagnostics, Marnes la Coquette, France) was employed to assess the immunity. Public day-care centers and schools were randomly selected, while three large antenatal clinics and maternity units were choosen by its importance. Population groups and results of 997 blood tests were: 227 children (mean age 3.8 years), 22.8% seropositives; 584 students (mean 11.4 years), 58.4%, and pregnant and postpartum women (mean 24 years), 71.5% seropositives (p < 0.001). Of 256 participants reporting close contact with cats, 59.8% were seropositive, in contrast with 51% seropositives without contact (relative risk 1.17; 95% confidence interval 1.04-1.33; p = 0.01). Having three or more siblings at home was related to higher seroprevalence in children and students (relative risk 1.39; 95% confidence interval 1.21-1.60; p < 0.01). In conclusion, toxoplasmosis seroprevalence showed a rapid increase during the first ten years of life, in association with close contact with cats and larger households, probably related to inappropriate hygiene and child-care practices.

Diabetes Gestacional - Rastreio Pós-Parto

Introdução: Um terço das mulheres com diabetes gestacional terá o diagnóstico de diabetes ou alteração do metabolismo da glicose no rastreio pós-parto. Objectivo: Avaliar a percentagem de mulheres submetidas a rastreio pós-parto e associar o resultado com a história materna. Métodos: Estudo retrospectivo de 1013 gravidezes com diabetes gestacional (2005-2009). Dividiu-se a população em dois grupos de acordo com o resultado: normal (grupo 1) e com diabetes ou alteração do metabolismo da glicose (grupo 2). Para ambos os grupos foram avaliados: idade materna, índice de massa corporal, ganho de peso na gravidez, idade gestacional do diagnóstico, necessidade de administração de insulina, factores de risco para diabetes gestacional e peso do recém-nascido. Resultados: O rastreio pós-parto foi realizado em 76,8% das mulheres (n=778). O teste foi considerado normal (grupo 1) em 628 mulheres(80,7%) e alterado (grupo 2) em 150 mulheres (19,3%). O Grupo 2 teve mulheres mais velhas (idade média de 34 vs 33 anos;p-value 0,013), com maior índice de massa corporal (28,5 vs 25,8kg / cm2; p-value 0,000), maior número de mulheres com história familiar em primeiro grau de diabetes mellitus (50,3% vs 39,9%; p-value 0,026) e história pessoal de macrossomia prévia (12,1% vs 5,4%; p-value 0,003). O diagnóstico mais precoce da diabetes gestacional foi também feito nesse grupo (27 vs 31 semanas; p-value 0,000) e uma maior percentagem efectuou insulina (41% vs 15%; p-value 0,000), tendo iniciado mais cedo a sua administração (28 vs 30 semanas; p-value 0,010). Verificou-se uma maior percentagem de grávidas multíparas no grupo 2 (64% vs 49,4%; p-value = 0,001) e um maior número de casos de recém-nascidos grandes para a idade gestacional (17,1% vs 8,3%; p-value = 0,001). A história pessoal de diabetes gestacional e ganho de peso durante a gestação foi semelhante nos dois grupos. Conclusões: As mulheres com alteração nos resultados do rastreio pós-parto são geralmente mais velhas, mais pesadas, multíparas, com história familiar em primeiro grau de diabetes Mellitus e história pessoal de macrossomia prévia. O diagnóstico de diabetes gestacional foi mais precoce neste grupo, mais frequentemente necessitaram de terapêutica com insulina com início mais cedo e verificou-se um maior número de recém-nascidos grandes para a idade gestacional.

Inferior Vena Cava Filter Placement During Pregnancy: an Adjuvant Option When Medical Therapy Fails

The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive option as prophylaxis for pulmonary embolism during pregnancy.

Contraceptive Choices Pre and Post Pregnancy in Adolescence

STUDY OBJECTIVE: The main aim of this study is to evaluate the impact of adolescent pregnancy in the future contraceptive choices. A secondary aim is to verify whether these choices differ from those made after an abortion. DESIGN: Retrospective study. SETTING:Adolescent Unit of a tertiary care center. PARTICIPANTS:212 pregnant teenagers. INTERVENTIONS: Medical records review. MAIN OUTCOME MEASURES:Intended pregnancy rate and contraceptive methods used before and after pregnancy. For contraceptive choices after pregnancy we considered: Group 1 - teenagers who continued their pregnancy to delivery (n = 106) and Group 2 - the same number of adolescents who chose to terminate their pregnancy. RESULTS: The intended pregnancy rate was 14.2%. Prior to a pregnancy continued to delivery, the most widely used contraceptive method was the male condom (50.9%), followed by oral combined contraceptives (28.3%); 18.9% of adolescents were not using any contraceptive method. After pregnancy, contraceptive implant was chosen by 70.8% of subjects (P < .001) and the oral combined contraceptives remained the second most frequent option (17.9%, P = .058). Comparing these results with Group 2, we found that the outcome of the pregnancy was the main factor in the choices that were made. Thus, after a pregnancy continued to delivery, adolescents prefer the use of LARC [78.4% vs 40.5%, OR: 5,958 - 95% (2.914-12.181), P < .001)], especially contraceptive implants [70.8% vs 38.7%, OR: 4.371 - 95% (2.224-8.591), P < .001], to oral combined contraceptives [17.9% vs 57.5%, OR: 0.118 - 95% CI (0.054-0.258), P < .001]. CONCLUSION:Adolescent pregnancy and its outcome constitute a factor of change in future contraceptive choice.

Qualidade em obstetrícia : complicações pós-parto e readmissões

RESUMO - A qualidade no sistema de saúde é alvo de grande preocupação por parte dos gestores, necessitando encontrar estratégias que conduzam a uma melhoria dos resultados das unidades hospitalares, em simultâneo com a contenção dos custos. O objectivo geral deste trabalho consistiu na avaliação da qualidade na área de obstetrícia nos hospitais públicos de Portugal Continental, através da análise das taxas de complicações pósparto e de readmissões verificando se existem diferenças por instituição hospitalar, volume, acreditação e região nos anos 2008 a 2010. Os dados foram cedidos pela Administração Central do Sistema de Saúde à Escola Nacional de Saúde Pública, sendo seleccionados os episódios nos GDH 370 a 375 e 650 a 652. Foram analisados 243 686 episódios, verificando-se que a taxa de incidência de complicações é superior nos partos por cesariana, comparativamente com os partos vaginais (1,66% e 1,03%, respectivamente). Os hospitais com maior volume de procedimentos e não acreditados evidenciam maiores taxas de complicação. A taxa de readmissão a 30 dias foi também superior na cesariana comparativamente ao parto vaginal (0,42% e 0,73%, respectivamente). Os hospitais com menor volume de procedimentos e acreditados, regra geral, são os que evidenciam as maiores taxas de readmissão. De salientar que as reduzidas taxas de complicações pós-parto verificadas poderão ser explicadas por diferenças na codificação dos diagnósticos secundários entre hospitais. Podem ainda existir diferenças aqui não consideradas entre os doentes tratados em cada instituição. Os dados apresentados permitem ter um melhor conhecimento acerca da qualidade no tratamento dos casos de obstetrícia nos hospitais públicos em Portugal Continental, dando indicações para a tomada de decisão em gestão em saúde.

Anesthesia for Ex Utero Intrapartum Treatment: Renewed Insight on a Rare Procedure

The ex utero intrapartum treatment is a rare surgical procedure performed in cases of expected postpartum fetal airway obstruction. The technique lies on a safe establishment of a patent airway during labor in anticipation of a critical respiratory event, without interrupting maternal-fetal circulation. Anesthetic management is substantially different from that regarding standard cesarean delivery and its main goals include uterine relaxation, fetal anesthesia and preservation of placental blood flow. We present the case of an ex utero intrapartum treatment procedure performed on a fetus with a large cervical lymphangioma and prenatal evidence of airway compromise. Modifications to the classic ex utero intrapartum treatment management strategies were successfully adopted and will be discussed in the following report.

Acute Sheehan's Syndrome Presenting as Central Diabetes Insipidus

Sheehan's syndrome occurs as a result of ischaemic pituitary necrosis due to severe postpartum haemorrhage. Improvements in obstetrical care have significantly reduced its incidence in developed countries, but postpartum pituitary infarction remains a common cause of hypopituitarism in developing countries. We report a case of severe postpartum haemorrhage followed by headache, central diabetes insipidus and failure to lactate, which prompted us to investigate and identify both anterior and posterior pituitary deficiency compatible with Sheehan's syndrome. A timely diagnosis allowed us to implement an adequate treatment and follow-up plan, which are known to improve clinical status and patient outcome.

Puerperal brain cryptococcoma in an HIV-negative woman successfully treated with fluconazole: a case report

Cryptococcus spp. cerebral abscesses are uncommon in immunocompetent subjects. The recommended induction treatment is the administration of amphotericin B plus flucytosine combined with resection for lesions ≥3cm. In this paper, we describe an HIV-negative woman diagnosed with a large cryptococcoma in the immediate postpartum period. The lesion was not resected, and due to amphotericin B intolerance, she received an extended course of fluconazole monotherapy. There was no disease recurrence during the 4 years of follow-up. The abrupt onset of her symptoms following delivery suggests that she developed a postpartum immune reconstitution syndrome. This case also demonstrates that in specific situations fluconazole monotherapy can be attempted in immunocompetent patients with cryptococcoma.
