Maternal Acceptance (maternal + acceptance)
Selected AbstractsTesting Central Postulates of Parental Acceptance-Rejection Theory (PARTheory): A Meta-Analysis of Cross-Cultural StudiesJOURNAL OF FAMILY THEORY & REVIEW, Issue 1 2010Ronald P. Rohner This meta-analysis addresses the following questions drawing from parental acceptance-rejection theory (PARTheory): (a) Is perceived rejection by an intimate partner in adulthood associated with the same form of psychological maladjustment that perceived parental rejection is known to be in childhood? (b) Are adults' remembrances of parental acceptance in childhood associated with their current psychological adjustment? (c) Do statistical relations vary by culture or gender? The meta-analysis was based on 17 studies involving 3,568 adults in 10 nations. Results showed that perceived partner acceptance in adulthood and remembered paternal and maternal acceptance in childhood tend to correlate highly with the current psychological adjustment of both men and women across all studies.

Weis Abstract The effect of military deployment and perceived availability and source of community support on women's acceptance of pregnancy were examined in each trimester of pregnancy at four military bases. The sample was 503 primigravida or multigravida women eligible for care in the military medical system. Military deployment and community support had a statistically significant effect on pregnancy acceptance. Gravidas with deployed husbands had higher conflict for accepting pregnancy than gravidas without deployed spouses. Community support had a significant positive effect on pregnancy acceptance. Women perceiving support predominantly from off-base versus on-base communities had significantly higher conflict with acceptance of pregnancy. Findings point to improved maternal acceptance of pregnancy with paternal presence and community support in the event of military deployment. Published 2008 Wiley Periodicals, Inc.

Noronha Citation Noronha LE, Antczak DF. Maternal immune responses to trophoblast: the contribution of the horse to pregnancy immunology. Am J Reprod Immunol 2010 The horse has proven to be a distinctively informative species in the study of pregnancy immunology for several reasons. First, unique aspects of the anatomy and physiology of the equine conceptus facilitate approaches that are not possible in other model organisms, such as non-surgical recovery of early stage embryos and conceptuses and isolation of pure trophoblast cell populations. Second, pregnant mares make strong cytotoxic antibody responses to paternal major histocompatibility complex class I antigens expressed by the chorionic girdle cells, permitting detailed evaluation of the antigenicity of these invasive trophoblasts and how they affect the maternal immune system. Third, there is abundant evidence for local maternal cellular immune responses to the invading trophoblasts in the pregnant mare. The survival of the equine fetus in the face of strong maternal immune responses highlights the complex immunoregulatory mechanisms that result in materno,fetal tolerance. Finally, the parallels between human and horse trophoblast cell types, their gene expression, and function make the study of equine pregnancy highly relevant to human health. Here, we review the most pertinent aspects of equine reproductive immunology and how studies of the pregnant mare have contributed to our understanding of maternal acceptance of the allogeneic fetus. [source] ORIGINAL ARTICLE: Soluble Human Leukocyte Antigen-G Isoforms in Maternal Plasma in Early and Late PregnancyAMERICAN JOURNAL OF REPRODUCTIVE IMMUNOLOGY, Issue 5 2009Roberta Rizzo Problem Human Leukocyte Antigen (HLA)-G is a class Ib gene located in the human major histocompatibility complex (MHC). Several lines of investigation indicate that the HLA-G molecule is involved in the maternal acceptance of the semi-allogenic fetus during pregnancy and in the development of tolerance. Expression of soluble HLA-G (sHLA-G) is positively correlated with successful in vitro fertilization (IVF) treatments, and aberrant expression of HLA-G in certain complications of pregnancy, such as pre-eclampsia and spontaneous abortion, has been reported. The main purpose of this study was to investigate the levels of different soluble HLA-G isoforms in maternal plasma in early and late pregnancy. Method of study Soluble HLA-G (sHLA-G) can be detected in maternal blood, and in this study, two different isoforms of sHLA-G, namely sHLA-G1 generated by shedding of membrane-bound HLA-G1 and HLA-G generated by specific HLA-G transcripts, have been investigated early [median of 16.4 weeks of gestation (GW)] and late (median: 38.9 GW) in pregnancy in an original cohort of 580 pregnant Caucasian women. Results Lower concentrations of sHLA-G1 were found late in pregnancy (>32 GW) in a group of women with severe pre-eclampsia compared with controls with uncomplicated pregnancies (P = 0.029, PC = 0.09; Mann,Whitney; Logistic regression analysis: P = 0.024, OR = 0.920, 95% CI: 0.855,0.989). However, this was not the case with HLA-G5, and significantly more of the cases with severe pre-eclampsia had detectable plasma HLA-G5 compared with that of the control group (P = 0.013, PC = 0.04; Mann,Whitney). Similar findings were not observed in women with gestational hypertension or existing hypertension continuing into pregnancy. Furthermore, there was a trend toward lower maternal plasma sHLA-G1 in a group of women with premature birth (<37 GW) compared with that of the control group (P = 0.028, PC = 0.17; Mann,Whitney). On the contrary, HLA-G5 was lower in the control group compared with that in the premature group (P = 0.004, PC = 0.02; Mann,Whitney). Conclusion This study shows in line with other published studies that a high, detectable soluble HLA-G concentration in maternal plasma or serum is not mandatory for a successful pregnancy. However, complications during pregnancy, such as (severe) pre-eclampsia, spontaneous abortion, IUGR, and premature birth, are associated with a low or undetectable level of soluble HLA-G in the maternal blood circulation. Also, this study indicates that sHLA-G1 is the interesting soluble HLA-G isoform in pre-eclampsia, and that low or undetectable levels of HLA-G5 at the end of pregnancy seem to be associated with an uncomplicated normal pregnancy, whereas in severe pre-eclampsia and possibly other pregnancy complications, such as preterm birth and IUGR, the level of HLA-G5 is higher.
