Cardiac disease and pregnancy.

The pregnant state imposes a supraphysiologic strain on the pregnant woman's cardiac performance through complex biochemical, electric, and physiologic changes affecting the blood volume, myocardial contractility, and resistance of the vascular bed. In the presence of underlying heart disease, these changes can compromise the woman's hemodynamic balance, her life, and that of her unborn child. Cardiac pathology represents a heterogeneous group of disorders, each with its own hemodynamic, genetic, obstetric, and social implications. Physicians caring for these women should actively address the issue of reproduction. Ideally, pregnancy should be planned to occur after optimization of cardiac performance by medical or surgical means. Once pregnancy is achieved, the concerted effort of a multidisciplinary team of obstetricians, cardiologists, anesthesiologists, nursing, social, and other services provides the best opportunity to carry the pregnancy to a successful outcome.

Influence of educational level on determinants of folic acid use.

In The Netherlands, periconceptional folic acid use to prevent neural tube defects was promoted through a national 'Folic Acid Campaign'. In two regions, a local campaign supplemented the national campaign to increase the chances of reaching women with low socio-economic status (SES). A framework of outcome criteria, defined as awareness knowledge, perceived safety, attitudes and subjective norms, was developed to evaluate the effectiveness of the two local campaigns. Data were gathered by means of two cross-sectional studies conducted just before and 1 year after the campaigns took place. Before the campaigns were conducted, there were already differences in all effect criteria and folic acid use between women of different educational levels, mostly in favour of women with a high level of education. Although both educational campaigns appeared to have a positive impact on all outcome criteria, they failed to reduce the existing differences in these outcome criteria between women of different educational levels. Folic acid use can be promoted effectively by mass media campaigns, certainly in a large group of women with no prior knowledge of the health benefits associated with periconceptional folic acid use. However, in order to achieve more equal health outcomes among women of low and high SES, it seems that more tailored interventions for women of low SES are needed.

Maternity services for women with diabetes in the UK.

Diabetic pregnancy is high risk in those regions within the UK that have reported on such an outcome. There is a paucity of information about diabetic pregnancy outcome in the rest of the UK but it seems appropriate to assume that poor outcome is widespread. Previously reports have highlighted problems with the delivery of preconception care and the lack of agreement about the screening and diagnosis of gestational diabetes. The provision of maternity services for women with diabetes in the UK is reviewed. Service development is traced from the 1980s to more recent surveys from Scotland and the former Northern region of England. Service provision has improved over the years in those regions that have agreed and audited standards for provision of care. There is a lack of information about current services within the UK but this will be partly addressed by the forthcoming survey of organization of services co-ordinated by the Confidential Enquiry into Stillbirths and deaths in Infancy (CESDI), which will survey England, Wales and Northern Ireland. In Scotland the Scottish Intercollegiate Guidelines 'Management of diabetes in pregnancy' has been implemented and audited. A similar guideline of agreed standards of care is needed for the rest of the UK.

Outcomes and health status of socially disadvantaged women during pregnancy.

We sought to examine the health status of disadvantaged pregnant women more broadly and to consider if poor maternal health predisposes a woman to an adverse birth outcome. We surveyed 250 women recruited from six health centers in the greater Boston area during their third trimester. The main predictor variables were maternal physical functioning (PF), emotional health (EH), and overall health status in the month prior to pregnancy. The main outcome variables were the decline of maternal PF and EH during pregnancy and adverse birth outcomes. Mean PF scores fell from 91.9 prior to pregnancy to 63.7 during the third trimester (mean scores transformed 0 to 100, where a higher score represents better health). EH remained unchanged during pregnancy. After adjustment, women with a preexisting medical condition reported a lower PF score prior to pregnancy (87.8 versus 94.5, p < 0.05). Poor PF prior to pregnancy or during the third trimester was associated with an increased risk of preterm labor (odds ratio 2.02, 95% confidence interval 1.03-3.97). This study is the first to employ general health status measures to examine changes in health during pregnancy. Our findings support the use of preconception care to improve the health status of disadvantaged women with pre-existing conditions. This study suggests that poor maternal health may predispose a woman to an increased risk of preterm labor.

The impact of environmental pollution on congenital anomalies.

Major congenital anomalies are diagnosed in 2-4% of births. In this paper we review epidemiological studies that have specifically looked at congenital anomalies as a possible outcome of community exposure to chemical exposures associated with environmental pollution. These include studies of drinking water contaminants (heavy metals and nitrates, chlorinated and aromatic solvents, and chlorination by-products), residence near waste disposal sites and contaminated land, pesticide exposure in agricultural areas, air pollution and industrial pollution sources, food contamination, and disasters involving accidental, negligent or deliberate chemical releases of great magnitude. We conclude that there are relatively few environmental pollution exposures for which we can draw strong conclusions about the potential to cause congenital anomalies and, if so, the chemical constituents implicated, to provide an evidence base for public health and clinical practice. A precautionary approach should be adopted at both community and individual level. In order to prevent congenital anomalies, one must reduce exposure to potential teratogens before pregnancy is recognized (i.e. preconceptionally and in the first few weeks of pregnancy). It is a challenge to develop effective strategies for preconceptional care within the primary care framework. Prenatal service providers and counsellors need to be aware of the uncertainties regarding environmental pollution when addressing parental concerns.

The use of pre-conceptional folic acid as an indicator of uptake of a health message amongst white and Bangladeshi women in Tower Hamlets, east London.

BACKGROUND: The benefit of folic acid is a simple health promotion message of proven effectiveness that is particularly pertinent to a young population with a high birth rate. OBJECTIVE: The aim of the present study was to compare the uptake of a folic acid health message in two different ethnic groups. METHODS: Community antenatal teams in Tower Hamlets were asked to recruit women attending for a booking between October 1997 and July 1998 to the study. Tower Hamlets, in east London, is one of the poorest areas in England and Wales, with an ethnically diverse population. A questionnaire enquiring about age, employment, level of education, use of folic acid in their current pregnancy, understanding of the benefits of folic acid and self-described ethnic group was administered verbally immediately before the booking appointment to those women who agreed to participate. RESULTS: Completed questionnaires were received on 249 women. Univariate analysis showed that white women were 5.7 [95% confidence interval (CI) 2.5, 13.2] times more likely to have taken folic acid supplements before conception than Bangladeshi women. Having controlled for the variables, age, school leaving age, social class, parity, planned pregnancy and 'heard of folic acid', ethnic status remained a significant predictor of taking folic acid, with the odds ratio dropping to 5.2 with a 95% CI (1.1, 25.2). CONCLUSION: The Bangladeshi community in the UK have been shown to have poor access to health information sources, which is consistent with the results of this survey, which shows that a simple and important message has not been acted upon equally by white and Bangladeshi women in east London. This survey lends support to the view that resources and innovative forms of health promotion are needed to ensure that ethnic minority groups have adequate access to health promotion messages.

Cardiac disease in pregnancy.

Cardiac disease complicates approximately 1% to 3% of pregnancies and is responsible for 10% to 15% of maternal mortality. The number of women of childbearing age with congenital disease is increasing as advances in diagnosis and treatment improve survival rates and overall health, allowing successful pregnancy. Pregnant women with severe cardiac disease or women who experience a cardiac event during pregnancy will require admission and stabilization in an adult critical care unit. This group of patients can prove challenging for the obstetrical staff and the critical care staff because they require blending of the knowledge and skills of 2 highly specialized areas of healthcare. The key component to a comprehensive and organized approach to management that ensures the best possible outcome for the woman is a multidisciplinary team that devises a plan on the basis of the most current information, communicates with each other and the patient effectively, and assumes responsibility for implementation of the plan. The purpose of this article is to review management of the woman with cardiac disease throughout pregnancy.

The physical, psychological, and social implications of caring for the pregnant patient and newborn with cystic fibrosis.

Cystic fibrosis (CF) involves the exocrine glands and epithelial tissues of the pancreas, sweat glands, and mucus glands in the respiratory, digestive, and reproductive tracts. Significant pulmonary disease, poor nutritional status, and pulmonary hypertension are results of chronic infections. When the woman with CF becomes pregnant, her body may find it difficult to adjust to the normal physiological changes of pregnancy, with the pulmonary, cardiovascular, and nutritional status being particularly stressed. Both the mother and the fetus are at a significant risk for increased morbidity and mortality. The woman whose life and pregnancy are compromised by CF and/or the newborn who is diagnosed with CF offer the nurse an extremely challenging situation--one in which physical and psychological care are proportional in importance. As part of the healthcare team, which includes a perinatologist, a pulmonary medicine specialist, a neonatologist, an anesthesiologist, a geneticist, a dietitian, a respiratory therapist, a social worker, an ethicist, and perhaps a clergyman, the nurse helps to coordinate and carry out the care needed for a successful outcome.

HIV and pregnancy: considerations for nursing practice.

This article describes current nursing practice for pregnant women with HIV. In the United States, the number of new cases of HIV continues to rise in women of childbearing age. Women often learn of their HIV status when a pregnancy involves them in the healthcare delivery system. Since the manifestation of the disease in 1981, there have been significant advances in treatment, and now, among pregnant women testing positive for HIV, the risk of perinatal transmission can be decreased to 1% with pharmacologic intervention. Yet, HIV disease poses many new challenges to the woman testing positive who is considering pregnancy or who is already pregnant. The progression of the symptoms of AIDS is similar to the common symptoms of pregnancy; the HIV medications may also cause these symptoms. Adherence to the HIV medication regime is necessary for ongoing viral suppression, for missed doses can initiate drug resistance and the whole categories of antiretroviral drugs may become ineffective. Additionally, the HIV stigma continues to impact those infected and interferes with the access to healthcare. HIV poses a major challenge for the nurse caring for the childbearing woman.

The quest for the perfect baby: why do Israeli women seek prenatal genetic testing?

Since the mid-1990s, the Israeli medical scene has witnessed a real boom in elective prenatal testing for inherited diseases that has spread beyond risk groups to the general Jewish population, especially of Ashkenazi (European) origin. This study tried to identify key social influences involved in the growing range and prevalence of prenatal genetic tests as they emerged from women's own perspective. Twenty-seven women having blood tests for genetic mutations were interviewed at two types of genetic clinics, and re-interviewed after getting test results. The names of 23 women who chose not to have elective tests were obtained from testers, and these non-testers were interviewed for comparison. Women's accounts suggest that elective genetic testing is more acceptable, if not normative, among educated middle class Ashkenazi women, and is more often questioned and refused by lower class Mizrahi women, as well as religious women of any ethnic origin. The key forces that drive women's choice of prenatal genetic diagnosis include the fear of having a sick and/or socially unfit child in an unsupportive environment; strong endorsement of testing by gynaecologists; popular and professional discourse on the common Ashkenazi mutations causing genetic anxiety in this ethnic group (i.e. apprehension of multiple known and unknown dangers hidden in its genetic makeup); and the emerging social pressure for comprehensive prenatal screening as an indispensable part of good motherhood. Many women described the experience of testing as frustrating because of the long wait for results and difficulty of their interpretation and subsequent decision-making. Women who rejected elective tests explained their decision by moral/religious objections to abortion and/or eugenic aspects of prenatal screening, as well as by prohibitive costs and poor understanding of the tests' meaning and implications. Yet, few informants voiced objections to the excessive medicalisation of pregnancy as such; ethno-national motives of reproductive decisions were also uncommon in this group. More critical reflection is clearly needed from both providers and users of elective genetic screening before the more widespread uptake of this practice.

Reproductive options for individuals at risk for transmission of a genetic disorder.

The basis of human growth and development has long been considered to be one of the great mysteries of science and mankind. The portal to understanding this mystery was achieved by the Human Genome Project and Celera Genomics in 2001, with their joint announcement of the sequencing of 99% of the human genome map. Current reproductive options, however, remain restricted to the prevention of transmitting an at-risk gene or genes, but do not include treatment or cure. It is anticipated that this state of "halfway technology" will continue for years to come. As such, the scientific and ethical issues associated with each of these reproductive options will continue to affect the decision making of at-risk individuals. As the omnipresent health care provider, nurses have a duty to know and disseminate accurate and current information about reproductive options for individuals at risk for transmission of a genetic disorder. Nurses also have a duty to advocate for and ensure the privacy and confidentiality of genetic information.

British HIV Association guidelines for prescribing antiretroviral therapy in pregnancy (1998).

The aim of antiretroviral therapy in pregnancy is to deliver a healthy uninfected child to a healthy mother, without prejudicing the future treatment opportunities of the mother. The use of zidovudine monotherapy rapidly became standard practice once it had been shown to reduce by 67% mother to child transmission in women with CD4+ lymphocyte counts above 200 x 10(6)/l. High rates of transmission are seen when maternal disease is advanced (high viral load, low CD4+ lymphocyte counts) despite zidovudine. In these women highly active antiretroviral therapy gives the best prospect for prolonged health and it is anticipated that reducing plasma viral load below the limits of detection will further reduce transmission rates. However, safety data for antiretroviral therapy in pregnancy are limited and each additional treatment exposes a significant proportion of uninfected infants to potential long term hazards. Where maternal therapy is not indicated and the sole objective of treatment is to reduce mother to child transmission, recent data suggest that short course zidovudine (especially in conjunction with prelabour caesarean section) is a reasonable option. This may minimise the emergence of viruses with reduced sensitivity to zidovudine and preserve maternal options for later therapy.
