The purposes of this study were to examine the accuracy of fetal hemoglobin (Hb F, alpha2gamma2) as quickly measured by a hemoximeter but verified by high performance liquid chromatography [HPLC, including Hb F total (Hb Ft), acetylated Hb F (Hb F1), and non acetylated Hb F ( Hb F*)], and to predict the Hb F levels for different gestational weeks of neonates. Thirty-nine neonates of predominantly Hispanic and African American ethnicity, with gestational ages ranging from 25 to 38 weeks, were investigated. Analyses were performed on 163 blood samples that were pure neonates' blood before the transfusion of any adult blood. Two neonates had increased Hb C [beta6(A3)Glu-->Lys, GAC-->AAG] levels (1.67-2.79%) and one neonate whose mother drank alcohol during pregnancy, had elevated Hb A2 levels (0.12-0.14%). After excluding these data points, the mean Hb F were overestimated by hemoximeter, 118.4 +/- 8.77% vs. 92.6 +/- 2.77% by HPLC (mean difference: 25.8 +/- 7.71%, p = <0.001). Mean Hb F1 was 10.5 +/- 2.28%. Hb F levels decreased as gestational age increased (p <0.001 for Hb Ft and Hb F*; p = <0.05 for Hb F1). A multivariate regression model for Hb F prediction was established with the best R2. The gestational age and post birth hours in the prediction of Hb Ft was included when Hb F could be determined at the clinical settings. Future studies may be needed to account for Hb F1 when measuring Hb F levels to assess oxygenation status in (pre term) neonates.

“…La langue et les différences culturelles sont les deux plus importantes barrières à l'utilisation des services de santé (Bischoff et al, 2003 ;Elderkin-Thompson, Cohen Silver et Waitzkin, 2001 ;Knox et Britt, 2002 ;Shiao, Andrews et Helmreich, 2005). La barrière linguistique affecte l'accès au système de santé, l'état de santé des patients, les résultats des soins de santé, la satisfaction et la sécurité des patients, ainsi que la communication, et augmente le recours aux services d'urgence et aux examens supplémentaires (Bischoff et al, 2003 ;Flores, 2005Flores, et 2006Knox et Britt, 2002).…”

La barrière linguistique réduirait le recours aux services préventifs, l’accès aux services basés sur la communication et augmenterait le recours aux services d’urgence. Les femmes sont particulièrement à risque à cause de leurs besoins accrus de services de santé et de soutien psychosociaux durant la grossesse, l’accouchement et la période du post-partum. Cette étude vise à recueillir de l’information sur les expériences de maternité des femmes francophones (Canadiennes et immigrantes) du Nouveau-Brunswick et de l’Alberta. Les résultats de cette étude seront utilisés pour améliorer les soins de santé et l’accès à l’information pour les femmes enceintes en situation linguistique et culturel minoritaire.Linguistic barriers may reduce the use of preventative services and access to communication-based services, and increase the use of emergency care. Women are particularly at risk owing to their increased need for health services and psychosocial support during pregnancy, birth and the post-partum period. We gathered information on the maternity experiences of Francophone women (Canadians and immigrants) in New Brunswick and Alberta. The results of the study will be used to improve health care and access to information for pregnant women in linguistic and cultural minority situations

“…This proportion rises to about one-half for women in lower socioeconomic populations. Smoking during pregnancy is more prevalent among Caucasian women compared with African-American or Hispanic women (70)(71)(72)(73). Women who smoke during pregnancy are more likely to be unmarried, have less education, lower incomes, and attend fewer prenatal visits compared with women who do not smoke during pregnancy (47).…”

Polycyclic aromatic hydrocarbons (PAH) come from incomplete combustion of organic materials, including tobacco smoke. Some PAH are known to be mutagenic and carcinogenic and of concern for the fetus when women smoke during pregnancy. Known consequences of smoking during pregnancy include low birth weight (LBW) and preterm (PT) delivery. This study was designed to measure concentrations of 3 PAH: anthracene (A), benzo(a)pyrene (BP) and 1-hydroxypyrene (1-HP) in paired maternal (M) and cord blood (CB) samples. Additionally, we explored relationships between the PAH concentrations and LBW or PTD. Cotinine was used as a biomarker of tobacco exposure. All 3 PAH were found in M and CB plasma. A was significantly elevated in CB plasma compared to M plasma at higher M cotinine concentrations. BP in PT infants was significantly lower than in term. There were significant correlations between M and CB concentrations of anthracene. Correlations of 1-HP with cotinine in CB and M plasma were significant but opposite in direction. Anthracene, benzo(a)pyrene and 1-hydroxypyrene are present in measurable concentrations in M and CB plasma at the time of delivery. The higher concentrations of anthracene in CB plasma may be due to differences in maternal metabolism during pregnancy, length of labor or metabolism in the fetus. Long-term effects of anthracene on the infant are unknown and merit further investigation.

Maternal Race/Ethnicity and Predictors of Pregnancy and Infant Outcomes

Abstract: There are obvious health disparities among White and non-White women experiencing high-risk pregnancies and births. Future studies are needed to develop interventions targeted to different racial/ethnic groups during pregnancy to reduce preterm and high-risk births.
