ABSTRACT

BACKGROUND: Public health messages urging women to seek health care services such as sexually transmitted diseases (STD) and cervical cancer screening or family planning services fail to address women who have sex with women (WSW). This negligence may have led to a false sense of security amongst WSW concerning sexual risk behaviour. Research has shown that WSW engaged in more high-risk sexual behaviours than heterosexual women. WSW has been identified as an important vector in the spread of STDs in all populations because of bisexuality. To prevent and reduce transmission of STDs amongst WSW, perceptions of risk for STD amongst WSW need to be understood so that effective interventions may be developed. AIM: To describe the relationship between sexual risk and protective behaviour and STD transmission amongst bisexual minority women with a history of STD. METHODS: Life history methods were used to interview 23 African-American bisexual women with a history of STD. FINDINGS: Various themes unfolded during analysis of the patient interviews, including bisexual women's perceptions of STD risk, the context of sexual relationships with women and STD prevention, screening, and treatment practices. CONCLUSIONS: The contexts of sexual relationships including multiple or concurrent partner relationships with both men and women placed these women at high risk for STD. Regardless of the type of relationship or belief it is possible to get an STD, protection was often not used. These circumstances identify an extremely high-risk population of women with need for more extensive research to identify strategies for health care interventions.

ABSTRACT

BACKGROUND: The role of intestinal transporter regulation in optimising nutrient absorption has been studied extensively in rodent and cell line models but not in human subjects. AIMS: The aim of the present study was to investigate the response in vivo of zinc transporters in the human enterocyte to dietary zinc supplementation. SUBJECTS: Eighteen patients who had previously undergone ileostomy, all free of any symptoms of inflammatory bowel disease. METHODS: Subjects took a daily zinc supplement of 25 mg for 14 days in a double blind, placebo controlled, crossover trial. The effect of the supplement on expression in ileal biopsies of the zinc transporters SLC30A1, SLC30A4, SLC30A5, SLC39A1, SLC39A4, and metallothionein was measured by reverse transcription-polymerase chain reaction RT-PCR. Expression of SLC30A1, SLC30A5, and SLC39A4 was also examined by immunoblotting. RESULTS: The zinc supplement reduced SLC30A1 mRNA (1.4-fold) together with SLC30A1, SLC30A5, and SLC39A4 protein (1.8-fold, 3.7-fold, and to undetectable levels, respectively) in ileal mucosa and increased metallothionein mRNA (1.7-fold). The supplement had no effect on expression of SLC30A4 or SLC39A1 mRNA. Localisation of SLC30A5 at the apical human enterocyte/colonocyte membrane and also at the apical membrane of Caco-2 cells was demonstrated by immunohistochemistry. Commensurate with these observations in zinc supplemented human subjects, SLC30A1, SLC30A5, and SLC39A4 mRNA and protein were reduced in Caco-2 cells cultured at 200 muM compared with 100 muM zinc. CONCLUSIONS: These observations indicate that, in response to variations in dietary zinc intakes, regulated expression of plasma membrane zinc transporters in the human intestine contributes to maintenance of zinc status.

ABSTRACT

Interferons are proteins produced by human blood cells in response to stimulation (viral infection). The natural roles of interferons are host defense and modulation of the immune system. Therapeutic uses are based on these roles. Interferon-alpha has been widely used for malignancies, skin conditions, viral infections, and myeloproliferative disorders. Interferon-beta is a standard treatment for relapsing multiple sclerosis. Interferon-gamma therapy is currently used for chronic granulomatous disease and skin lesions (human papilloma virus related and keloids), but further research is ongoing. Side effects of interferon therapy are common and limit utility. Flulike symptoms are reported by more than 75% and depression by 10-40% of interferon users. Severe adverse effects are less common but may be life threatening, including autoimmune diseases, thrombotic-thrombocytopenic purpura, and acute renal failure. Limited use of interferon therapy during pregnancy has been described, with successful maternal and neonatal outcomes. Use of interferon therapy during early pregnancy is not an indication for termination.

ABSTRACT

The distribution of platinum, rhodium, and palladium (platinum-group elements; PGEs) adjacent to two major U.K. roads shows a rapid decrease (more than 1 order of magnitude) away from the road and reflects patterns shown by other traffic-derived trace elements such as Pb and Zn. However, ratios of Pt:Rh remain relatively constant from 0 to 10 m distance, suggesting that at least some of the PGEs are transported away from the source. A temporal study over a 12-month period, of road dust and surface samples, reveals elevated concentrations above background levels, with maximum values of Pt >500 ng g(-1), Rh 70 ng g(-1), and Pd 70 ng g(-1). Concentrations vary considerably throughout the year and show some tentative correlation with rainfall. Element speciation, an essential control on mobility and hence distribution, was investigated, and the results of solubility experiments show that up to 30% of the Pd present dissolves in acid solutions. This indicates that at least some of the Pd is present in a soluble form and is therefore potentially highly mobile.

ABSTRACT

OBJECTIVE: Our purpose was to define influences on the patterns of the vaginal microflora. STUDY DESIGN: We enrolled 617 African American and Mexican American women in a 1-year longitudinal study of sexual behaviors and the vaginal microflora on the basis of the presence of gonorrhea, chlamydial infection, trichomoniasis, or syphilis at the initial visit. The patients were assigned randomly to a behavioral intervention or standard counseling regarding sexually transmitted disease. We reevaluated 508 (82%) and 549 (89%) women at 6 and 12 months, respectively. A comprehensive survey of lower genital tract organisms was conducted at baseline and at 6 and 12 months. Behavioral and microbiologic associations were screened by bivariate analysis. All variables associated with an organism at P < or = .15 were included in a multivariate analysis. Associations between behavior and the genital tract microflora were identified by logistic regression coefficients with P <.05. RESULTS: African American race had a consistent association with vaginal microflora, specifically, Mycoplasma hominis, Trichomonas vaginalis, bacterial vaginosis, group B streptococci, Neisseria gonorrhoeae, and Chlamydia trachomatis. Various behaviors had a less consistent effect, including multiple partners, douching, frequency of coitus >3 times a week, and cunnilingus, fellatio, and anal intercourse at the last sexual encounter. M hominis (but not Ureaplasma urealyticum ), Gardnerella vaginalis, and Lactobacillus species were associated with bacterial vaginosis. Lactobacillus species appeared to protect against bacterial vaginosis and infection with G vaginalis. Sexually transmitted diseases (caused by M hominis, N gonorrhoeae, C trachomatis, and T vaginalis ) were associated with each other. In contrast, hormonal status, vaginal blood, and foreign bodies had little effect. CONCLUSION: The presence of other microorganisms and race have a more consistent association with the presence or absence of a cervical-vaginal organism than sexual behavior, hormonal status, vaginal devices, or the presence of abnormal vaginal bleeding.

ABSTRACT

OBJECTIVE: Group B streptococcal colonization in pregnancy has been associated with adverse perinatal outcomes, including intra-amniotic infection, postpartum endometritis, and neonatal sepsis. We sought to determine whether gestational diabetes increases the risk of maternal and neonatal morbidity from group B streptococcal colonization. METHODS: Gestational diabetic and nondiabetic women who underwent vaginal or anogenital culture for group B streptococcus colonization in pregnancy were followed up for pregnancy outcome. Antibiotic prophylaxis was not routinely given. Major perinatal morbidity included intraamniotic infection, endometritis, and neonatal sepsis. Potential confounding variables included induction of labor, cesarean delivery, prematurity, maternal antibiotic use, and prolonged rupture of membranes. RESULTS: We compared 446 gestational diabetic women to 1,046 nondiabetic women for outcome. Overall, 12% were colonized with group B streptococcus, with no difference in colonization rates between gestational diabetic (12%) and nondiabetic (12%) women. There were no differences in intraamniotic infection rates between gestational diabetic and nondiabetic women, whether group B streptococcus positive (16% compared with 13%) or group B streptococcus negative (10% compared with 11%). Likewise, endometritis did not differ (6-9%) regardless of diabetes or group B streptococcus status. Neonatal sepsis was higher in group B streptococcus-positive women overall (3% compared with 1%, odds ratio 3.71, 95% confidence interval 1.23, 10.81), but did not differ between diabetic and nondiabetic pregnancies. CONCLUSION: Gestational diabetes does not alter the perinatal morbidity associated with group B streptococcal colonization in pregnancy.

ABSTRACT

BACKGROUND: African-American and Hispanic women are disproportionately affected by sexually transmitted diseases, including the acquired immunodeficiency syndrome (AIDS). In the effort to reduce infection rates, it is important to create and evaluate behavioral interventions that are specific to the target populations. METHODS: We enrolled women with nonviral sexually transmitted diseases in a randomized trial of a sex- and culture-specific behavioral intervention. The intervention consisted of three small-group sessions of three to four hours each designed to help women recognize personal susceptibility, commit to changing their behavior, and acquire necessary skills. The control group received standard counseling about sexually transmitted diseases. The design of the intervention was based on the AIDS Risk Reduction Model and ethnographic data on the study populations. Participants in both groups underwent screening, counseling, and an interview before randomization and at the 6- and 12-month follow-up visits. The principal outcome variable was subsequent chlamydial or gonorrheal infection, which was evaluated on an intention-to-treat basis by logistic-regression analysis. RESULTS: A total of 424 Mexican-Americans and 193 African-American women were enrolled; 313 were assigned to the intervention group and 304 to the control group. The rate of participation in the intervention was 90 percent. The rates of retention in the sample were 82 and 89 percent at the 6- and 12-month visits, respectively. Rates of subsequent infection were significantly lower in the intervention group than in the control group during the first 6 months (11.3 vs. 17.2 percent, P=0.05), during the second 6 months (9.1 vs. 17.7 percent, P=0.008), and over the entire 12-month study period (16.8 vs. 26.9 percent, P=0.004). CONCLUSIONS: A risk-reduction intervention consisting of three small-group sessions significantly decreased the rates of chlamydial and gonorrheal infection among Mexican-American and African-American women at high risk for sexually transmitted disease.

ABSTRACT

Fetuses born after pregnancies complicated by diabetes display delayed pulmonary maturation as measured by the delayed appearance of biochemical indicators of pulmonary maturity (phosphatidylglycerol, lecithin/sphingomyelin ratio) and by the occurrence of hyaline membrane disease even in term gestations. We tested the hypothesis that poor maternal glycemic control is associated with delayed appearance of the biochemical markers of fetal pulmonary maturation. Consecutive diabetic pregnancies with documentation of maternal glycemic control and amniotic fluid analysis for PG were analyzed. Maternal glycemic control was defined as good if the mean blood glucose was < or = 5.8 mmol/L (105 mg/dl) and poor if > 5.8 mmol/L. The presence of amniotic fluid phosphatidylglycerol was considered an indicator of lung maturity. Hyaline membrane disease was defined by the criteria of Corbet et al. [J Pediatr 118:277-284, 1991]. A total of 621 diabetic pregnancies were analyzed (261 good glycemic control, 360 poor glycemic control). Phosphatidylglycerol was absent in 21% of good glycemic control vs. 31% of poor glycemic control pregnancies (P < 0.05). When stratified by gestational age, the risk of absence of phosphatidylglycerol was significantly higher in the poor glycemic control group (O.R. 1.83, 1.19-2.84). At 36-37.9 weeks, poor glycemic control pregnancies had significantly higher rates of absent phosphatidylglycerol (37% vs. 22%, O.R. 2.04, 1.1-3.9). All cases of hyaline membrane disease beyond 32 weeks gestation occurred in poor glycemic control pregnancies. There were no cases of hyaline membrane disease beyond 37.0 weeks gestation. We conclude that poorly controlled maternal glucose levels are associated with delayed appearance of phosphatidylglycerol in diabetic pregnancies. However, after 37.0 weeks of gestation, no significant neonatal pulmonary disease occurred.

ABSTRACT

OBJECTIVE: To test the hypothesis that the presence of meconium-stained amniotic fluid (AF) is associated with maternal and neonatal infection, both before and after delivery. METHODS: Nine hundred thirty-six laboring women were analyzed for the presence of meconium in amniotic fluid and occurrence of peripartum infection. Meconium was assessed clinically as thin, moderate, or thick. Intra-amniotic infection and endometritis were diagnosed by standard definitions. All patients were tested for vaginal group B streptococcus, bacterial vaginosis, and other aerobic organisms. RESULTS: Meconium-stained AF was present in 28% of the study participants (9% thin, 12% moderate, 7% thick). The presence of meconium was associated with increased intra-amniotic fluid (17% versus 9%, relative risk [RRI 1.98, 95% confidence interval [CI] 1.3, 3.1), endometritis (10% versus 5%, RR 2.38, 95% CI 1.3, 4.4), and total infection (25% versus 13%, RR 2.19, 95% CI 1.5, 3.2). Thick meconium had higher infection rates than clear AF (44% versus 13%, RR 5.18, 95% CI 2.9, 9.3). Meconium was associated independently with peripartum infection by multiple logistic regression (RR 1.28, 95% CI 1.1, 1.6). CONCLUSION: Meconium-stained AF is associated with increased peripartum infection, independent of other risk factors for infection. Thick meconium, in particular, is associated with a marked increase in peripartum infectious morbidity.

ABSTRACT

OBJECTIVE: To determine the efficacy, safety, and duration of induced labor using an integrative approach (prostaglandin, amniotomy, oxytocin) and to depict these findings graphically. METHODS: Five hundred ninety-seven pregnancies requiring induction of labor between October 1993 and May 1995 were analyzed prospectively. Patients were categorized by Bishop score at entry and by parity for comparison of success of induction, maternal and fetal complications, and duration of labor. RESULTS: The women who had a Bishop score at entry of 3 or less had significantly higher rates of failed induction (9.4 versus 0.7%, P < .01) and of cesarean delivery (29 versus 15.4%, P < .01) than those with a Bishop score above 3. Compared with spontaneous labor, the rates of cesarean delivery in induced labor remained significantly elevated. Complications of induction were infrequent, regardless of Bishop score. The time from initiation of induction to achievement of active phase was significantly longer in women with lower Bishop scores. CONCLUSION: Regardless of cervical status and parity, vaginal delivery can be anticipated in the majority of patients undergoing labor induction. The induction characteristics described may assist in the management of induced labor.

ABSTRACT

OBJECTIVES: Inadequate prenatal care is thought to be a major modifiable risk factor for preterm birth, the leading cause of neonatal mortality. To improve high-risk women's financial access to prenatal care, the U.S. Medicaid program underwent major expansions during the 1980s. We evaluated these expansions over the nine-year period 1983 to 1991 in Tennessee to determine their effects on Medicaid enrollment, use of prenatal care, and preterm birth. METHODS: We used linked birth certificates, Medicaid data, and U.S. Census files to identify 610,056 singleton births to African-American or Caucasian women in Tennessee whose last menstrual period was between 1983 and 1991. These were classified by maternal characteristics to identify groups with the greatest postexpansion increases in Medicaid enrollment, which should have benefited most from the policy changes. Study outcomes were Medicaid enrollment by delivery, enrollment in the first trimester, inadequate prenatal care (modified Kessner index), and preterm (< 37 weeks) birth. We calculated the changes (delta expressed as births per 100) between 1983 and 1991 in percentages of births with each of these outcomes. RESULTS: The expansions led to pronounced increases in maternal Medicaid enrollment by delivery (21% of births in 1983 to 51% by 1991) and in the first trimester (from 10% to 37%). Married women with < 12 years of education, < 25 years of age, and < $12,500 mean neighborhood incomes (group 1) had the greatest increase, where enrollment and first-trimester enrollment increased from 24% to 86% and 7% to 68%, respectively. In group 1, the percentages of births with inadequate maternal use of prenatal care decreased substantially, from 12.8% in 1983 to 6.4% in 1991, a reduction of 6.4 births per 100 (95% confidence intervals [CI] = -7.6, -5.3). However, the preterm birth rate did not decrease (9.1% in 1983, 9.4% in 1991, change of 0.3[-0.7 to 1.2] births per 100). For other births, there were lesser increases in Medicaid enrollment, correspondingly lesser decreases in inadequate use of prenatal care, but no reductions in preterm birth rates. CONCLUSIONS: In Tennessee, the Medicaid expansions materially increased enrollment and use of prenatal care among high-risk women, but did not reduce the likelihood of preterm birth.

ABSTRACT

Induction of labour, defined as stimulation of uterine contractions before the spontaneous onset of labour, is indicated when the condition of the mother or fetus precludes awaiting the onset of spontaneous labour. In current medical practice, induction of labour comprises 2 phases: cervical priming and induction of contractions. Although numerous agents have been used for cervical priming, the current standard of care is the use of intracervical or intravaginal prostaglandin E2. The only drug currently used for induction of contractions is intravenous oxytocin. While many protocols are deemed acceptable, when required, the use of cervical priming, amniotomy and intravenous oxytocin are advocated. Utilising this approach, rapid delivery can be obtained in the majority of women.

ABSTRACT

To characterize the underlying neuroanatomic substrate of morphine (MS) sensitization, changes in the local cerebral metabolic rate for glucose (LCMRglu) were examined in 95 brain regions of male F-344 rats using the 2-deoxy-D-[1-14C]glucose method. The results of these experiments demonstrate that MS-induced sensitization is manifested by increases in basal metabolic activity that last for at least 6 days. Although changes in basal metabolic rate were found to be more extensive in the presence of conditioned cues, the increases in LCMRglu in nonconditioned sensitized rats indicate a basic underlying pharmacologic effect of MS sensitization on basal brain activity. Regions in which MS sensitization had a lasting pharmacologic effect include the shell of the nucleus accumbens, the prelimbic area of the prefrontal cortex, and the dorsolateral prefrontal cortex. Interestingly, the core of the nucleus accumbens and regions of the caudate were found to have an increased LCMRglu only in the presence of conditioned cues, indicating conditioned brain activity without observable changes in behavior. The previous administration of an MS-sensitizing treatment was also found to alter the cerebral metabolic response to a subsequent acute MS challenge (0.5 mg/kg, subcutaneously), most notably in forebrain systems. The more widespread activation of brain structures in the basal state in the presence of conditioned cues suggests that these MS-sensitized rats may model an altered brain state related to craving in the abstinent opiate addict.

ABSTRACT

OBJECTIVE: To test the hypothesis that preeclamptic women are more readily inducible than are nonpreeclamptic women, regardless of cervical condition. METHODS: One hundred eighty-three preeclamptic women and 461 nonpreeclamptic women requiring labor induction were studied prospectively. Patients were categorized by Bishop score, parity, gestational age, and method of induction. Outcome variables were success of induction and cesarean delivery rates. RESULTS: Failed induction was significantly more common in the preeclamptic group (8.2% versus 1.7%; odds ratio [OR] 5.06; 95% confidence interval [CI] 1.97, 13.28), as was cesarean delivery (28% versus 16%; OR 2.09; 95% CI 1.36, 3.18). When controlled by logistic regression for Bishop score, parity, method of induction, epidural anesthesia, macrosomia, and gestational age, a fourfold higher risk of failed induction and a twofold higher risk of cesarean delivery were found in the preeclamptic group. CONCLUSIONS: Induction of labor in preeclamptic women has a higher risk of failure and consequently of cesarean delivery than in nonpreeclamptic women. The vast majority of patients achieve vaginal delivery.

ABSTRACT

OBJECTIVES: To ascertain the type and order of maneuvers that should be used for the treatment of shoulder dystocia, and to determine its correlation with perinatal outcome. METHODS: We reviewed all consecutive cases of shoulder dystocia from January 1986 to August 1994 in our institution to obtain the type, order and number of maneuvers used for delivery. Patients were stratified by the number of maneuvers required for delivery. Outcome parameters included cord pH, Apgar score, neonatal trauma (Erb's palsy and fracture), and maternal trauma. RESULTS: The incidence of shoulder dystocia was 0.7% (39,280 total vaginal deliveries). Use of only two maneuvers, McRoberts and suprapubic pressure, resulted in resolution in 58% of cases. The addition of the Woods screw maneuver and/or delivery of the posterior arm was sufficient in all remaining cases. The rates of neonatal palsy and fracture, and maternal four-degree laceration, increased with the number of maneuvers. CONCLUSIONS: The McRoberts maneuver and suprapubic pressure should be first-line treatment for shoulder dystocia. More difficult and damaging maneuvers such as Woods screw and delivery of the posterior arm may be reserved for refractory cases. Additional maneuvers are rarely necessary for delivery. The number of maneuvers may serve as a measure of the severity of the shoulder dystocia.

ABSTRACT

OBJECTIVE: To test the hypothesis that in normotensive pregnancies decreased maternal glucose response leads to relative fetal hypoglycemia and hypoinsulinemia, which result in delayed fetal growth. STUDY DESIGN: We enrolled patients with and without risk factors for growth retardation. Each underwent an oral glucose tolerance test with both glucose and insulin evaluation. Cord blood was obtained for glucose and insulin evaluation. RESULTS: The normotensive pregnancies at risk had lower maternal glucose levels (index, 91 vs. 116 mg/dL; P < .05), a trend toward lower maternal insulin levels (index, 398 vs. 483 muIU/mL; P = NS) and normal maternal insulin/glucose ratios. We found no differences, however, in the fetal metabolic parameters (glucose 83 vs. 78 mg/dL, insulin 17 vs. 24 muIU/mL; P = NS). CONCLUSION: Maternal glucose metabolism is altered in nonhypertensive pregnancies, with a risk of delayed fetal growth; however, the fetal glucose response may remain normal in the face of fetal growth retardation.

ABSTRACT

OBJECTIVE: To determine the effects of maternal antenatal treatment with tocolytics, corticosteroids and the use of combined tocolytics and corticosteroids on the morbidity and mortality of very low birth weight infants. STUDY DESIGN: This retrospective study was conducted on all infants born in Tennessee in 1989 and 1990 who weighed < 1,500 g at birth and had no serious malformations. Registered nurses traveled to the delivery hospitals of all study subjects and abstracted information using a structured data collection form. Mortality was ascertained through the computerized linkage of birth and death certificates. Multiple logistic regression analysis was used to control for covariates. RESULTS: As compared to infants whose mothers received no treatment, infants whose mothers received both corticosteroids and tocolysis had a reduced risk of infant (odds ratio 0.38, 95% confidence interval 0.25-0.58) and neonatal mortality (OR 0.32, CI 0.19-0.51) as well as a reduced risk of seizures (OR 0.46, CI 0.23-0.93). Restricting the analysis of infants at 24-28 weeks' gestation and < 1,000 g at birth revealed similar findings regarding mortality. CONCLUSION: The use of combined corticosteroids with tocolytics was associated with better neonatal outcomes than the use of corticosteroids alone, tocolytics alone or no treatment.

OBJECTIVE: To test the hypothesis that fetal growth restriction (FGR) associated with a maternal hypertensive disorder results in worse perinatal outcome than FGR in pregnancies without maternal hypertension. METHODS: All consecutive, singleton, nondiabetic, small for gestational age (SGA) deliveries (birth weight at or below the tenth percentile for gestational age) in a 15-year computerized data base were analyzed for pregnancy outcome. Perinatal outcome was compared after stratification by presence or absence of hypertensive disorders and by gestational age at delivery. RESULTS: Eleven thousand two hundred twenty-seven SGA pregnancies were analyzed. The morbidity and mortality profiles differed between hypertensive and normotensive pregnancies delivered preterm and those delivered at term. Perinatal mortality was significantly higher in the normotensive than in the hypertensive group in preterm deliveries (30.3 versus 18.7%, odds ratio [OR] 1.9 [confidence interval (CI) 1.3-2.9]). At term, hypertensive pregnancies demonstrated significantly higher mortality than normotensive pregnancies (4.6 versus 1.9%, OR 2.42 [95% CI 1.7-3.4]). In both preterm and term gestations, cesarean rates were significantly higher in hypertensive pregnancies than in normotensive pregnancies. Using logistic regression analysis, hypertension was independently associated with a 39% reduction in risk of perinatal mortality preterm, compared with a twofold increased risk of perinatal mortality at term. CONCLUSION: Before term, FGR in normotensive women resulted in significantly higher perinatal mortality than FGR in hypertensive women. In contrast, at term, FGR in pregnancies complicated by hypertension had poorer perinatal outcomes than FGR in normotensive women.
