Idade materna como fator de risco: estudo com primigestas na faixa etária igual ou superior a 28 anos

Trata-se de estudo transversal, cujo objetivo foi analisar a idade materna como fator de risco ou não, através da verificação de intercorrências na gestação, parto e puerpério de primigestas com idade igual ou superior a 28 anos e das condições de nascimento e alta de seus recém-nascidos, comparando-as com o grupo de primigestas na faixa etária de 20 a 27 anos. Foi realizado em Botucatu/S.P., no período de janeiro de 1990 a junho de 1995. A análise estatística, discutida ao nível de 5% de significância, foi realizada através da prova de Mann-Whitney, teste de Goodman e avaliação do risco relativo e risco relativo corrigido, através da técnica de Mantel-Haenszel. Concluiu-se que a idade materna igual ou superior a 28 anos não constituiu fator de risco gestacional, puerperal e intra-parto mas, por outro lado, foi fator de risco, mesmo após controlado o tipo de parto, para as seguintes intercorrências perinatais: taquipnéia transitória do recém-nascido, cianose generalizada ao nascer e infecção neonatal.

Descriptive study of HTLV infection in a population of pregnant women from the state of Pará, Northern Brazil

INTRODUÇÃO: No Brasil, estudos mostram que a soroprevalência do HTLV entre gestantes varia de 0 a 1,8%. Contudo, esta soroprevalência era desconhecida no Estado do Pará, Brasil. O presente estudo descreve, pela primeira vez, a soroprevalência do HTLV entre gestantes do Estado do Pará, Norte do Brasil. MÉTODOS: 13,382 gestantes foram submetidas à triagem para HTLV durante o pré-natal, e aquelas com sorologia alterada para anti-HTLV foram submetidas ao teste de Western Blot (WB), para confirmar e discriminar portadoras do HTLV-1 e do HTLV-2. RESULTADOS: A soroprevalência do HTLV na população de gestantes foi de 0,3%, sendo o HTLV-1 identificado em 95,3% das pacientes. O perfil demográfico das portadoras do HTLV foi de: mulheres com idade entre 20-40 anos (78,4%); residentes na região metropolitana de Belém (67,6%) e com nível educacional igual ao ensino médio (56,8%). Outras variáveis relacionadas à infecção foram: início das relações sexuais compreendido entre 12-18 anos (64,9%), e ter sido aleitada mais de 6 meses (51,4%). A maior parte das mulheres estudadas teve ao menos duas gestações anteriores (35,1%); e nenhum aborto (70,3%). Co-infecções (sífilis e HIV) foram descritas em 10,8% (4/37) das gestantes. A soroprevalência da infecção pelo HTLV em gestantes atendidas em Unidades Básicas de Saúde do Estado do Pará, Norte do Brasil foi de 0,3% semelhante à descrita em outros estudos brasileiros. As variáveis relacionadas com a infecção são indicadores importantes na identificação de gestantes com maior tendência a soropositividade pelo HTLV, sendo uma estratégia de controle e prevenção, evitando a transmissão vertical.

Depression and anxiety in pregnant women with diabetes or mild hyperglycemia

A number of physical and psychological changes that occur during pregnancy can stimulate the development of psychological disorders such as anxiety and depression. The study evaluated psychological aspects related to maternal depression and anxiety in pregnant women with diabetes mellitus or hyperglycemia, contrasting the results with those of non-diabetic pregnant women. In a prospective and longitudinal approach, two questionnaires were applied and validated for use in Brazil, the Beck depression inventory and the State-Trait Anxiety Inventory. The questionnaires were applied to pregnant women at the first prenatal visit or at the time of disease diagnosis (T1) and reapplied at admission for delivery (T2). Regardless of the degree of hyperglycemia, both at first and in the second stage most women had severe anxiety trait. In early pregnancy (T1), however, severe state anxiety was more frequent in women with hyperglycemia than in those from the NG group. Most pregnant women showed moderate state anxiety over their pregnancy, regardless of glycemic status. In early pregnancy, however, severe state anxiety was more prevalent in hyperglycemic women than in those with normal glycemic status. Most women showed moderate trait anxiety and mild depression in both early and late pregnancy, irrespective of glycemic status. The incidence of severe state anxiety in early pregnancy is more frequent in women with diabetes or hyperglycemia, but their levels of trait anxiety and depression are not affected by glycemic status.

Effect of Type 2 Diabetes Mellitus on the Pharmacokinetics of Metformin in Obese Pregnant Women

Background and Objective The use of metformin throughout gestation by women with polycystic ovary syndrome (PCOS) and type 2 diabetes mellitus (T2DM) significantly reduces the number of first-trimester spontaneous abortions and the rate of occurrence of gestational diabetes and hypertensive syndromes. Metformin is taken up into renal tubular cells by organic cation transport 2 (OCT2) and eliminated unchanged into the urine. The objective of this study was to analyse the influence of T2DM on the pharmacokinetics of metformin in obese pregnant women and in a control group of non-diabetic obese pregnant women with PCOS. Methods Eight non-diabetic obese pregnant women with PCOS and nine obese pregnant women with T2DM taking oral metformin 850 mg every 12 h were evaluated throughout gestation. Serial blood samples were collected over a 12-h period during the third trimester of pregnancy. Steady-state plasma concentrations of metformin were determined by high-performance liquid chromatography with a UV detector. The pharmacokinetic results of the two groups, reported as median and 25th and 75th percentile, were compared statistically using the Mann Whitney test, with the level of significance set at p < 0.05. Results The pharmacokinetic parameters detected for PCOS versus T2DM patients, reported as median, were, respectively: elimination half-life 3.75 versus 4.00 h; time to maximum concentration 2.00 versus 3.00 h; maximum concentration 1.42 versus 1.21 mu g/mL; mean concentration 0.53 versus 0.56 mu g/mL; area under the plasma concentration time curve from time zero to 12 h 6.42 versus 6.73 mu g.h/mL; apparent total oral clearance 105.39 versus 98.38 L/h; apparent volume of distribution after oral administration 550.51 versus 490.98 L; and fluctuation (maximum minimum concentration variation) of 179.56 versus 181.73%. No significant differences in pharmacokinetic parameters were observed between the groups. Conclusion T2DM in the presence of insulin use does not influence the pharmacokinetics of metformin in pregnant patients, demonstrating the absence of a need to increase the dose, and consequently does not influence the OCT2-mediated transport in pregnant women with PCOS.

Congenital Chagas disease: time to screen pregnant women?

The congenital transmission of Trypanosoma cruzi has gained epidemiological importance because it is partially responsible for the spread of Chagas disease worldwide. The feasibility of a cure when infected children are treated early makes the detection of congenital infection a valuable goal toward the control of the disease. Here, the authors review and discuss the findings of Bua et al., who quantified the parasitemia of infected women and their newborns by quantitative PCR. The authors demonstrate that the maternal parasite burden is directly related to the risk of neonatal infection. This study points out the importance of a quantitative screen for T. cruzi in pregnant women who live in, or have traveled to, endemic areas for improving the diagnosis of infected newborns and providing prompt treatment.

Preferences of first-time expectant mothers for care of their child : 'I wouldn't leave them somewhere that made me feel insecure'

Australia has witnessed a continual increase in maternal employment over the past two decades, which places focus on both supply of childcare and a demand for high quality care. This study examined childcare preferences regarding the return to paid work of 124 Australian women who were expecting their first child. In contrast with most studies that have retrospective designs, the design of this study presents the perspectives of women prior to the birth of their first child-that is, before they have made a final decision about child care. This study found that the majority (78 per cent) of the women intended to re-commence work within the 12 months after the birth of their child. There were two factors that were the most salient features in their decision making-the quality of care and the personal satisfaction of engaging in paid work. The findings suggest that family friendly employment practices and access to secure, high-quality child care are key to women's secure participation in the paid workforce.

Weight gain and nutritional intake in obese pregnant women : some clues for intervention

Aim:  Maternal obesity is associated with increased risk of adverse outcomes for mothers and offspring. Strategies to better manage maternal obesity are urgently needed; however, there is little evidence to assist the development of nutrition interventions during antenatal care. The present study aimed to assess maternal weight gain and dietary intakes of overweight and obese women participating in an exercise trial. Results will assist the development of interventions for the management of maternal overweight and obesity. Methods:  Fifty overweight and obese pregnant women receiving antenatal care were recruited and provided dietary and weight data at baseline (12 weeks), 28 weeks, 36 weeks gestation and 6 weeks post-partum. Data collected were compared with current nutritional and weight gain recommendations. Associations used Pearson's correlation coefficient, and ANOVA assessed dietary changes over time, P < 0.05. Results:  Mean prepregnancy body mass index was 34.4 ± 6.6 kg/m2. Gestational weight gain was 10.6 ± 6 kg with a wide range (−4.1 to 23.0 kg). 52% of women gained excessive weight (>11.5 kg for overweight and >9 kg for obese women). Gestational weight gain correlated with post-partum weight retention (P < 0.001). Dietary intakes did not change significantly during pregnancy. No women achieved dietary fat or dietary iron recommendations, only 11% achieved adequate dietary folate, and 38% achieved adequate dietary calcium. Very few women achieved recommended food group servings for pregnancy, with 83% consuming excess servings of non-core foods. Conclusion:  Results provide evidence that early intervention and personalised support for obese pregnant women may help achieve individualised goals for maternal weight gain and dietary adequacy, but this needs to be tested in a clinical setting.

Comparison of PCR, nested PCR, and random amplified polymorphic DNA PCR for detection and typing of Ureaplasma urealyticum in specimens from pregnant women

A PCR assay, using three primer pairs, was developed for the detection of Ureaplasma urealyticum, parvo biovar, mba types 1, 3, and 6, in cultured clinical specimens. The primer pairs were designed by using the polymorphic base positions within a 310- to 311-bp fragment of the 5* end and upstream control region of the mba gene. The specificity of the assay was confirmed with reference serovars 1, 3, 6, and 14 and by the amplified-fragment sizes (81 bp for mba 1, 262 bp for mba 3, and 193 bp for mba 6). A more sensitive nested PCR was also developed. This involved a first-step PCR, using the primers UMS-125 and UMA226, followed by the nested mba-type PCR described above. This nested PCR enabled the detection and typing of small numbers of U. urealyticum cells, including mixtures, directly in original clinical specimens. By using random amplified polymorphic DNA (RAPD) PCR with seven arbitrary primers, we were also able to differentiate the two biovars of U. urealyticum and to identify 13 RAPD-PCR subtypes. By applying these subtyping techniques to clinical samples collected from pregnant women, we established that (i) U. urealyticum is often a persistent colonizer of the lower genital tract from early midtrimester until the third trimester of pregnancy, (ii) mba type 6 was isolated significantly more often (P 5 0.048) from women who delivered preterm than from women who delivered at term, (iii) no particular ureaplasma subtype(s) was associated with placental infections and/or adverse pregnancy outcomes, and (iv) the ureaplasma subtypes most frequently isolated from women were the same subtypes most often isolated from infected placentas.

What are pregnant women told about models of maternity care in Australia? A retrospective study of women's reports

Objective To describe women’s reports of the model of care options General Practitioners (GPs) discussed with them at the first pregnancy consultation and women’s self-reported role in decisionmaking about model of care. Methods Women who had recently given birth responded to survey items about the models of care GPs discussed, their role in final decision-making, and socio-demographic, obstetric history, and early pregnancy characteristics. Results The proportion of women with whom each model of care was discussed varied between 8.2% (for private midwifery care with home birth) and 64.4% (GP shared care). Only 7.7% of women reported that all seven models were discussed. Exclusive discussion about private obstetric care and about all public models was common, and women’s health insurance status was the strongest predictor of the presence of discussions about each model. Most women (82.6%) reported active involvement in final decision-making about model of care. Conclusion Although most women report involvement in maternity model of care decisions, they remain largely uninformed about the breadth of available model of care options. Practical implications Strategies that facilitate women’s access to information on the differentiating features and outcomes for all models of care should be prioritized to better ensure equitable and quality decisions.

Vaccination for pregnant women: Need to address

Pregnancy is a critically important state for any women in her life time. Administration of a vaccine to a pregnant woman is not a routine event and it is generally preferred to administer vaccines either prior to conception or in the postpartum period. Currently vaccination with inactivated vaccines are recommended due to potential risk to mother and fetus with live vaccines. Multiple factors determine the administration of the vaccines for example age, life style, medical conditions (e.g., asthma, diabetes etc.), type and location of travel and status of previous vaccination. If pregnant woman is exposed to these vaccines or if pregnancy occurs soon after vaccination, the women should be counselled regarding the risks to the fetus and vaccination should not be a reason to consider termination of pregnancy. Further research in vaccination among pregnancy is warranted for the safety of the pregnant women and their newborn for a healthy living and better life.

Breaking New Ground: The First Generation of Women to Work as Professional Authors in English Canada (1880-1920)

In the later decades of the nineteenth century and the early decades of the twentieth, large numbers of Canadian women were stepping out of the shadows of private life and into the public world of work and political action. Among them, both a cause and an effect of these sweeping social changes, was the first generation of Canadian women to work as professional authors. Although these women were not unified by ideology, genre, or date of birth, they are studied here as a generation defined by their time and place in history, by their material circumstances, and by their collective accomplishment. Chapters which focus on E. Pauline Johnson (Tekahionwake), the Eaton sisters (Sui Sin Far and Onoto Watanna), Joanna E. Wood, and Sara Jeannette Duncan explore some of the many commonalities and interrelationships among the members of this generation as a whole. This project combines archival research with analytical bibliography in order to clarify and extend our knowledge of Johnson’s and Duncan’s professional lives and publishing histories, and to recover some of Wood’s “lost” stories. This research offers a preliminary sketch of the long tradition of the platform performance (both Native and non-Native) with which Johnson and others engaged. It explores the uniquely innovative ethnographic writings of Johnson, Duncan, and the Eaton sisters, among others, and it explores thematic concerns which relate directly to the experiences of working women. Whether or not I convince other scholars to treat these authors as a generation, with more in common than has previously been supposed, the strong parallels revealed in these pages will help to clarify and contextualize some of their most interesting work.

Peer-mentoring for first-time mothers from areas of socio-economic disadvantage: a qualitative study within a randomised controlled trial

Objective: To explore the difficulties experienced by lay-workers, women and health professionals involved in a peer-mentoring programme for first-time mothers living in socially disadvantaged areas. Design: Qualitative study; semi-structured interviews with lay-worker peer-mentoring programme participants at two separate stages of the programme (antenatal and postnatal). Setting: Community based. Participants: 11 women receiving peer-mentoring support (from first hospital antenatal visit to one year postnatal); 11 lay-workers; 2 research midwives. Results: Lay-workers had difficulty initiating contact with women and failure to establish contact affected their morale adversely. They felt that women understood their intended role poorly and attempted to develop relationships with them by sharing personal experiences and offering friendship; women who participated in the programme appreciated this. Developing a peer-mentor relationship was difficult if women lacked interest in the programme or in continuing contact. External influences on peer-mentoring uptake and delivery included family and friends who could prevent or encourage women’s participation and cause difficulties for the lay-worker both in delivering support and arranging follow-up. Lay-workers providing support to women from a different ethnic background experienced difficulties relating to both language and culture: these were perceived to affect peer-mentor relationships adversely. Major personal difficulties for lay-workers related to time constraints in reconciling mentoring requirements with demands of family and other work. Informing midwives of these difficulties helped identify solutions through training and ongoing professional support for the lay-workers. Conclusions: Lay-worker peer support is appreciated by first time mothers but difficulties in initiating contact, developing peer-mentor relationships and external influences such as family, ethnicity and time constraints are relevant to poor uptake and high staff turnover. In developing peer support programmes, awareness of potential difficulties and of how professional support can help resolve these should improve uptake and thus optimise the evaluations of their effectiveness.

A RCT of peer-mentoring for first-time mothers in socially disadvantaged areas (the moments study)

Objective: Interventions to reduce health inequalities for young children and their mothers are important: involving peers is recommended, but evidence of value for this approach is limited. The authors aimed to examine the effect of an innovative tailored peer-mentoring programme, based on perceived needs, for first-time mothers in socio-economically deprived communities. Design: Randomised controlled trial; parallel qualitative study with purposive samples using semistructured interviews. Setting: Socio-economically disadvantaged areas, Belfast. Participants: Primigravidae, aged 16-30 years, without significant co-morbidity. Intervention: Peer-mentoring by a lay-worker fortnightly during pregnancy and monthly for the following year, tailored to participants' wishes (home visits/telephone contacts), additional to usual care. Main outcome measures: Infant psychomotor and mental development (Bayley Scales of Infant Development (BSID-II)) at 1 year, assessed by an observer blinded to group allocation. Mothers' health at 1 year postnatal (SF-36). Results: Of 534 women invited, 343(64%) participated; 85%, with their children, completed outcome assessments (140 of 172 intervention; 152 of 171 controls). Intervention and control groups did not differ in BSID-II psychomotor (mean difference 1.64, 95% CI -0.94 to 4.21) or mental (-0.81, -2.78 to 1.16) scores, nor SF-36 physical functioning (-5.4, -11.6 to 0.7) or mental health (-1.8, -6.1 to 2.6). Women valued advice given in context of personal experience of child-rearing. Mentors gained health-related knowledge, personal skills and new employment opportunities. Conclusions: Despite possible longer-term social advantage, this peer-mentoring programme showed no benefit for infant development or maternal health at 1 year. Further rigorous evaluation of important outcomes of complex interventions promoting health for children in socially disadvantaged communities is warranted. Trial registration no: ISRCTN 55055030.
