Home care of high risk pregnant women by advanced practice nurses: nurse time consumed. (1/2239)

This study examined the time spent by advanced practice nurses (APNs) in providing prenatal care to women with high risk pregnancies. The results indicate that the overall mean APN time spent in providing prenatal care was 51.3 hours per woman. The greatest amount of time was spent in the clinic and women with pregestational diabetes consumed the most APN time and required the most contacts. Historically, home care services have been measured by number of visits or contacts. This study assists home care nurses and administrators to consider additional measurements including time spent.  (+info)

Maternal smoking and Down syndrome: the confounding effect of maternal age. (2/2239)

Inconsistent results have been reported from studies evaluating the association of maternal smoking with birth of a Down syndrome child. Control of known risk factors, particularly maternal age, has also varied across studies. By using a population-based case-control design (775 Down syndrome cases and 7,750 normal controls) and Washington State birth record data for 1984-1994, the authors examined this hypothesized association and found a crude odds ratio of 0.80 (95% confidence interval 0.65-0.98). Controlling for broad categories of maternal age (<35 years, > or =35 years), as described in prior studies, resulted in a negative association (odds ratio = 0.87, 95% confidence interval 0.71-1.07). However, controlling for exact year of maternal age in conjunction with race and parity resulted in no association (odds ratio = 1.00, 95% confidence interval 0.82-1.24). In this study, the prevalence of Down syndrome births increased with increasing maternal age, whereas among controls the reported prevalence of smoking during pregnancy decreased with increasing maternal age. There is a substantial potential for residual confounding by maternal age in studies of maternal smoking and Down syndrome. After adequately controlling for maternal age in this study, the authors found no clear relation between maternal smoking and the risk of Down syndrome.  (+info)

Influence of prenatal iron and zinc supplements on supplemental iron absorption, red blood cell iron incorporation, and iron status in pregnant Peruvian women. (3/2239)

BACKGROUND: It is estimated that 60% of pregnant women worldwide are anemic. OBJECTIVE: We aimed to examine the influence of iron status on iron absorption during pregnancy by measuring supplemental iron absorption, red blood cell iron incorporation, and iron status in pregnant women. DESIGN: Subjects were 45 pregnant Peruvian women (33+/-1 wk gestation), of whom 28 received daily prenatal supplements containing 60 mg Fe and 250 microg folate without (Fe group, n = 14) or with (Fe+Zn group, n = 14) 15 mg Zn, which were were consumed from week 10 to 24 of gestation until delivery. The remaining 17 women (control) received no prenatal supplementation. Iron status indicators and isotopes were measured in maternal blood collected 2 wk postdosing with oral (57Fe) and intravenous (58Fe) stable iron isotopes. RESULTS: Maternal serum ferritin and folate concentrations were significantly influenced by supplementation (P < 0.05). Serum iron was also significantly higher in the Fe than in the Fe+Zn (P < 0.03) or control (P < 0.001) groups. However, the supplemented groups had significantly lower serum zinc concentrations than the control group (8.4+/-2.3 and 10.9+/-1.8 micromol/L, respectively, P < 0.01). Although percentage iron absorption was inversely related to maternal serum ferritin concentrations (P = 0.036), this effect was limited and percentage iron absorption did not differ significantly between groups. CONCLUSIONS: Because absorption of nonheme iron was not substantially greater in pregnant women with depleted iron reserves, prenatal iron supplementation is important for meeting iron requirements during pregnancy.  (+info)

A management information system for nurse/midwives. (4/2239)

The experiences of nurse/midwives with a simple management information system in the private sector are reported from four facilities in Nigeria. When such a system is being introduced, special attention should be given to strengthening the ability of health workers to record and collate data satisfactorily.  (+info)

A strategy for reducing maternal mortality. (5/2239)

A confidential system of enquiry into maternal mortality was introduced in Malaysia in 1991. The methods used and the findings obtained up to 1994 are reported below and an outline is given of the resulting recommendations and actions.  (+info)

Mediators of ethnic-associated differences in infant birth weight. (6/2239)

PURPOSE: To examine whether ethnic differences in low birth weight babies of low-income women may be explained in part by group differences in prenatal health behaviors and psychosocial factors. METHODS: A prospective, survey of 1,071 low-income, primiparous African-American and Mexican-origin women was conducted in Los Angeles County, California. In face-to-face interviews, data were obtained on substance use, prenatal stress, social support, attitudes toward pregnancy, initiation of prenatal care, and medical risk. Medical chart data were abstracted regarding medical risk factors and labor, delivery, and neonatal data. Interview data were linked with birth outcome data retrieved from maternal medical records. Structural equation modeling was used to test a hypothesized model in which differences in birth weight were expected to be mediated by ethnic differences in substance use, psychosocial factors, and medical risk. RESULTS: As expected, African-American women delivered babies of earlier gestational age and lower birth weight than did women of Mexican origin. Direct predictors of low birth weight were use of drugs and cigarettes, prenatal stress, and positive attitudes toward pregnancy; together, these factors accounted for the observed ethnic differences in birth weight. CONCLUSION: These data contribute to our understanding of the factors that may account for ethnic-associated differences in low birth weight.  (+info)

Erythema infectiosum (Fifth disease) and pregnancy. (7/2239)

QUESTION: One of my patients is currently 14 weeks pregnant. She is a teacher in grade 1, and there is an epidemic of Fifth disease in the school where she teaches. Can this disease affect her pregnancy and how should I care for her? ANSWER: Erythema infectiosum (Fifth disease) is usually a benign disease for children and mothers, but might have serious consequences for a fetus due to hemolytic anemia, although the risk is very low. You should evaluate the mother's immune status. If she is already immune (IgG positive), the risks are nil. If she is not immune (although the risk of the fetus's being affected is very low), fetal surveillance by repeated ultrasonographic examination and immune status reevaluation has been recommended. If a fetus is found to be affected, intrauterine evaluation and treatment are available at tertiary care centres.  (+info)

Maternity care calendar wheel. Improved obstetric wheel developed in British Columbia. (8/2239)

PROBLEM BEING ADDRESSED: Gestational calendar "wheels" are not well designed for routine prenatal care or for presenting the uncertainties of predicting date of delivery. OBJECTIVE OF PROGRAM: To design and pilot-test a new gestational calendar wheel that predicts the range of normal due dates in a way that reflects the biological realities of pregnancy. The calendar has prompts that could facilitate provision of antenatal care, support prenatal education, and guide the timing of induction for pregnancies past their due dates. MAIN COMPONENTS OF PROGRAM: The calendar sets out the key issues to be addressed with patients during pregnancy. It is designed to be photocopied while set to patients' dates: patients keep one copy; another is placed in their charts. The probability of delivering on a given date is presented graphically and as a percentage likelihood of giving birth during specified intervals. Twelve practising physicians, 12 residents, and 10 pregnant women pilot-tested and evaluated the wheel. Their responses were favourable. CONCLUSIONS: The Maternity Care Calendar wheel is a substantial advance on existing obstetric calendar wheels. It incorporates evidence-based information that should facilitate prenatal care, promote prenatal education, and foster realistic expectations about the likely timing of delivery. Early in the pregnancy, it can help establish the timing of induction for pregnancies past their due dates. Further testing of the calendar's effectiveness in improving patient outcomes is needed.  (+info)
