Communicating with African-American Women Who Have Had a Preterm Birth About Risks for Future Preterm Births.

PURPOSE: African-American women are at higher risk of preterm birth (PTB) compared with other racial/ethnic groups in the USA. The primary objective was to evaluate the level of understanding among a group of African-American women concerning risks of PTB in future pregnancies. Secondary objectives were to evaluate how some women obtain information about PTB and to identify ways to raise their awareness. METHODS: Six focus groups were conducted in three locations in the USA during 2016 with women (N = 60) who had experienced ≥ 1 PTB (< 37 weeks of gestation) during the last 5 years. The population was geographically, economically, and educationally diverse. RESULTS: We observed a tendency to normalize PTB. Knowledge about potential complications for the infant was lacking and birth weight was prioritized over gestational age as an indicator of PTB. Participants were largely unaware of factors associated with increased PTB risk, such as a previous PTB and race/ethnicity. The most trusted information source was the obstetrical care provider, although participants reported relying on mobile apps, websites, and chat rooms. The optimal time to receive information about PTB risk in subsequent pregnancies was identified as the postpartum visit in the provider's office. CONCLUSIONS: Awareness of the risks of recurrent PTB was limited in this diverse population. Educational programs on the late-stage development of neonates may strengthen knowledge on the relationship between gestational age and PTB and associated health/developmental implications. For educational efforts to be successful, a strong nonjudgmental, positive, solutions-oriented message focused on PTB risk factors is crucial.

Interleukin-33-induced expression of PIBF1 by decidual B cells protects against preterm labor.

Preterm birth (PTB) is a leading cause of neonatal death worldwide. Intrauterine and systemic infection and inflammation cause 30-40% of spontaneous preterm labor (PTL), which precedes PTB. Although antibody production is a major immune defense mechanism against infection, and B cell dysfunction has been implicated in pregnancy complications associated with PTL, the functions of B cells in pregnancy are not well known. We found that choriodecidua of women undergoing spontaneous PTL harbored functionally altered B cell populations. B cell-deficient mice were markedly more susceptible than wild-type (WT) mice to PTL after inflammation, but B cells conferred interleukin (IL)-10-independent protection against PTL. B cell deficiency in mice resulted in a lower uterine level of active progesterone-induced blocking factor 1 (PIBF1), and therapeutic administration of PIBF1 mitigated PTL and uterine inflammation in B cell-deficient mice. B cells are a significant producer of PIBF1 in human choriodecidua and mouse uterus in late gestation. PIBF1 expression by B cells is induced by the mucosal alarmin IL-33 (ref. 9). Human PTL was associated with diminished expression of the α-chain of IL-33 receptor on choriodecidual B cells and a lower level of active PIBF1 in late gestation choriodecidua. These results define a vital regulatory cascade involving IL-33, decidual B cells and PIBF1 in safeguarding term pregnancy and suggest new therapeutic approaches based on IL-33 and PIBF1 to prevent human PTL.

Differences in cytogenetic sensitivity to ionizing radiation in newborns and adults.

Radiation exposure causes DNA breaks leading to structural chromosome aberrations that can be carcinogenic. Lifetime cancer risks are elevated in irradiated children compared to similarly exposed adults. To determine the extent to which age influences the frequency and types of chromosome damage in response to ionizing radiation, peripheral blood samples were collected from 20 adults (aged 22-78 years) and from the umbilical cords of 10 newborns and acutely exposed to 0 (control), 1, 2, 3 or 4 Gy of cobalt-60 gamma rays. Cells were cultured in the presence of the mitogen phytohemagglutinin, harvested at 48 h and then evaluated for structural chromosome aberrations by fluorescence in situ hybridization whole chromosome painting. Regression analyses were used to evaluate radiation-induced translocated chromosomes, dicentrics, acentric fragments, color junctions and aberrant cells to determine whether the frequencies of these events was dependent upon age. Peripheral blood lymphocytes from newborns showed statistically significant increases in the induced frequencies of translocated chromosomes, dicentrics, acentric fragments, color junctions and abnormal cells at several radiation doses when compared to blood from adults. No significant changes in sensitivity with age were observed when adults were evaluated separately. We conclude that peripheral lymphocytes from newborns are significantly more prone to radiation-induced chromosome aberrations than peripheral lymphocytes from adults. The increased sensitivity of newborns in this study relative to adults was found to be 37(±9)%, 18(±4)%, 12(±2)% and 4(±5)% at doses of 1, 2, 3 and 4 Gy, respectively. These data may be relevant when making radiation exposure risk assessments.

Management of pregnant patients with diabetes with ischemic heart disease.

Management of pregnant patients with diabetes who have ischemic heart disease (IHD) remains a challenging clinical dilemma for obstetricians and maternal fetal specialist alike. The diagnosis of women with IHD is difficult, primarily because of a lack of awareness of the atypical characteristics at presentation by both patient and provider. Counseling of women regarding pregnancy when they are diabetic with IHD is best done before conception. Management by trimester should focus on careful monitoring of maternal cardiac status and stabilization of glycemic control without hypoglycemia. Delivery and postpartum care remain critical in the avoidance of complications and mortality.

Alcohol use in pregnancy: insights in screening and intervention for the clinician.

Alcohol consumption during pregnancy remains a common occurrence and is associated with a multitude of adverse birth and long-term outcomes. Binge drinking in particular is shown to be particularly harmful to the developing fetus. Effects include full fetal alcohol syndrome, with characteristic facial dysmorphology, growth restriction, and developmental to delays. Exposed children may also have partial fetal alcohol syndrome, alcohol-related birth defects, and alcohol-related neurodevelopmental disorders. These effects are preventable, and efforts must begin with accurate identification of women who consume alcohol during pregnancy. Several screening tools have been developed and validated for use in prenatal care settings, and the most recently proposed brief and easy to use T-ACER3 has demonstrated high sensitivity and specificity in both identifying risk drinking during pregnancy and predicting long-term neurobehavioral outcomes in exposed children. Once identified, effective interventions are available for use with pregnant women consuming alcohol. Brief interventions, which can be delivered by a health professional and involve motivational interviewing, have been demonstrated to significantly reduce alcohol consumption during pregnancy. These approaches, recommended by American College of Obstetricians and Gynecologist (ACOG), help move patients toward increased readiness to positively change their drinking behavior. Ultimately, all prenatal care providers should routinely screen all patients for alcohol use using validated tools, and where appropriate, should offer intervention.

Adverse obstetric outcomes associated with sonographically identified large uterine fibroids.

STUDY OBJECTIVE: To determine the impact of sonographically identified large uterine fibroids (>5 cm in diameter) on obstetric outcomes. DESIGN: Retrospective cohort study. SETTING: University teaching hospital. PATIENT(S): Women with singleton gestations (n = 95) noted to have uterine fibroids on obstetric ultrasonography from September 2009 through April 2010 and age-matched controls (n = 95). INTERVENTION(S): None. MAIN OUTCOME MEASURE(S): Obstetric outcomes including short cervix, preterm premature rupture of membranes, and preterm delivery. RESULT(S): Compared to women with no fibroids or small fibroids (≤5 cm), women with large fibroids (>5 cm) delivered at a significantly earlier gestational age (38.6 vs. 38.4 vs. 36.5 weeks). Short cervix, preterm premature rupture of membranes, and preterm delivery were also significantly more frequent in the large fibroid group, and were associated with number of fibroids >5 cm in diameter. Blood loss at delivery was significantly higher in the large fibroid group (486.8 vs. 535.6 vs. 645.1 mL), as was need for postpartum blood transfusion (1.1 vs. 0.0 vs. 12.2%). CONCLUSION(S): Women with large uterine fibroids in pregnancy are at significantly increased risk for delivery at an earlier gestational age compared to women with small or no fibroids, as well as obstetric complications including excess blood loss and increased frequency of postpartum blood transfusion.

Tuberculosis in pregnancy.

Tuberculosis is known as the great masquerader and the manifestation of the disease can be vague and widespread. Worldwide, TB kills more women each year than any other infection and the greatest burden of disease occurs in those in the reproductive age. Screening strategies in pregnancy provides a unique opportunity to identify and treat at-risk women for tuberculosis. In this review, we identify the current screening, treatment, and breastfeeding strategies for tuberculosis in pregnancy.

Psychosocial dimensions of HIV infection in pregnancy.

As more experience has accrued regarding human immunodeficiency virus (HIV) infection in women and HIV infection in pregnancy, there has remained a gap in our understanding of the psychosocial effects of HIV infection upon the pregnant women. There is limited information regarding psychologic and sociologic effects of HIV infection upon pregnancy and vice versa; there is sufficient indication of a relationship between stressors related to each of these and the potential for a deleterious affect upon the pregnancy. These stresses often include the determination whether to disclose or not disclose their serostatus.

Lipids and lactate in human immunodeficiency virus-1 infected pregnancies with or without protease inhibitor-based therapy.

OBJECTIVE: To evaluate the effect of protease inhibitors on lipid and lactate levels and gastrointestinal symptoms in pregnancy. METHODS: Acquired Immunodeficiency Syndrome (AIDS) Clinical Trials Group (ACTG) A5084 was an observational cohort study of human immunodeficiency virus (HIV)-infected pregnant women. Women recruited between 20 and 34 weeks of gestation were required to be on a stable, highly active antiretroviral therapy (HAART) regimen, stratified by protease inhibitor compared with no protease inhibitor regimens. Interval history was assessed, and lipid and lactate levels were drawn every 8 weeks during pregnancy and 12 weeks postpartum, with levels closest to delivery and postpartum used for analysis. Statistical comparisons used Kruskal-Wallis and Fisher exact tests. RESULTS: One-hundred fifty-eight women were evaluated. Total cholesterol levels (median 230 mg/dL, interquartile range [197, 259], compared with 212 [179, 246] mg/dL, P=.042) and triglycerides (median 224 mg/dL, interquartile range [187, 288], compared with 185 [142, 230] mg/dL, P<.001] were elevated in the protease inhibitor group during pregnancy and remained higher in this group after delivery (total cholesterol 185 [163, 224] mg/dl compared with 171 [140, 190] mg/dL, P<.004; triglycerides 122 [87, 175] mg/dL compared with 89 [66, 150] mg/dL, P=.02). No difference was seen in lactate levels or rates of gastrointestinal symptoms between groups. Obstetric outcomes were similar between the two groups. A higher number of low birth weight infants were born to women in the highest twentieth percentile of triglycerides compared with the lowest across medication groups. CONCLUSION: Cholesterol and triglycerides were higher in protease inhibitor-treated women in pregnancy. Lactate and gastrointestinal symptoms were not different. A higher number of low birth weight infants were noted in women with high triglycerides, but other elevated lipid levels did not affect pregnancy outcomes.

Postpartum morbidity associated with advanced HIV disease.

OBJECTIVE: To investigate the postpartum morbidity and postpartum management of febrile morbidity associated with advanced HIV infection. METHODS: A case control study of HIV infected women at a tertiary care center during January 2000-June 2005 was performed. Postpartum morbidity was defined as endometritis, blood transfusion, wound complication, readmission, infectious morbidity, or unexpected surgery. RESULTS: Women in Group 1 had AIDS (N=33), Group 2 were relatively immunocompetent HIV infected women (N=115), and Group 3 were uninfected women (N=152). Group 1 was more likely to have a postpartum morbidity (32.3 versus 19.3 and 13.2%, P=.03) and to have postpartum imaging 18.8 versus 7.9 and 2.6%, P=.002. After controlling for potential confounders, cesarean delivery (OR 6.2, 95% CI 2.1-505.5) but not advanced HIV disease was associated with an increased risk of postpartum morbidity. CONCLUSION: Cesarean delivery and not advanced HIV disease increases the risk of postpartum morbidity in women with AIDS.

Characteristics associated with suboptimal viral suppression at delivery in human immunodeficiency virus-1-infected pregnant women.

OBJECTIVE: This study was undertaken to determine clinical characteristics and factors associated with suboptimal viral suppression at delivery in human immunodeficiency virus (HIV)-infected women. STUDY DESIGN: All HIV-infected women who delivered at a single urban tertiary care center from January 1999 to June 2004 were studied. Women were divided into 2 groups based on HIV viral load (VL) proximate to delivery: VL < 1000 copies per milliliter and VL > or = 1000 copies per milliliter. Demographic and clinical factors were analyzed and compared between the 2 groups. RESULTS: A total of 146 women had adequate data available for analysis: 102 (69.9%) had VL < 1000 copies per milliliter and 44 (30.1%) had VL > or = 1000 copies per milliliter at delivery. Women with a viral load > or = 1000 copies per milliliter at delivery were more likely to have a baseline viral load VL > or = 10,000 copies per milliliter (66.7% vs 32%, P < .001) and less likely to report medication adherence, (50% vs 87.8%, P < .001). CONCLUSION: Our findings support the concept that in addition to antiviral medical therapy, intervention to improve adherence and maintaining a low baseline VL are key components to VL suppression in pregnancy.

Voluntary HIV counseling and testing of pregnant women--an assessment of compliance with Michigan public health statutes.

OBJECTIVES: First, to evaluate compliance with Michigan's laws mandating universal, voluntary HIV counseling and testing (VCT) of all pregnant women who provide informed consent (ie, the "opt-out strategy"). Second, to assess the acceptability of and agreement to VCT. METHODS: Women who delivered a live infant at a large, urban academic medical center were interviewed before hospital discharge. Obstetric and prenatal medical records were abstracted to document that VCT was offered, accepted, or declined and that pre- and posttest counseling were provided and test results noted. RESULTS: Our survey of 491 postpartum women interviewed from February 1998 through January 1999 revealed that 83% reported that they were offered VCT; of those, 95% reported that they had agreed to testing. Uninsured women were least likely to undergo VCT; no other demographic, social, or behavioral characteristics were associated with VCT. Nor was VCT more likely to occur according to providers' different practice settings (ie, "private" vs publicly funded). Most women reported that they did not find VCT offensive or threatening, although only 49% reported that they felt "very comfortable," refusing testing. CONCLUSION: These results suggest the opt-out strategy for VCT, as currently practiced in Michigan, can effectively promote the US Public Health Service testing goals. Offering VCT with the understanding that it may be refused without risk is essential. Additional educational interventions about HIV infection during pregnancy and perinatal HIV-transmission interruption were requested by women in our study and should be widely promoted. Given that 95% of women agreed to VCT, mandatory testing without consent is not needed to achieve federal testing benchmarks and seems ethically problematic.
