Sexual Minority and Heterosexual Parents Adopting Through the Child Welfare System: Challenges and Surprises During the Transition to Parenthood and Beyond

This session will address some of the unexpected challenges and surprises encountered by heterosexual, lesbian, gay, and bisexual individuals and couples who adopt through the child welfare system. Data will be presented regarding (a) the challenges that foster-to-adopt parents encounter post-placement, including: legal insecurity in their parental role, disorganization within social service systems, inadequate support services, and complex relationships with birth parents; (b) unmet expectations that foster-to-adopt parents often encounter with regard to the types of children that are placed in their home (e.g., in terms of age, race, gender, and special needs); and (c) the experiences of parents that have adopted via child welfare in terms of contact and openness with birth family members. Engaged and informal discussion of the implications of these findings for families and clinicians, as well as Q&A, will follow these brief research presentations

Consequences of Prenatal Stress on Appetite Control and the Energy Expenditure Pathway

Established research has illustrated that moderate exposure to stress in the womb influences both adult phonotype and genotype for several physiological pathways, especially in males. Proposed explanations include adaptions made by the fetus resulting from a limited supply of nutrients, referred to as the thrifty phenotype. In this study, we examine this fetal programming effect on the appetite control and energy expenditure pathways in prenatally stressed adult male offspring. Subjects were male rats born from time-mated female rats exposed to unpredictable, variable prenatal stress (UVPS) throughout gestation. An analysis of the adult male rat offspring genetic expression of epididymal fat pads and the plasma concentrations of hormones involved in appetite control and energy expenditure pathways showed a significantly diminished expression of leptin and adiponectin compared to unstressed controls. Leptin and adiponectin are both major hormones involved in the appetite control and energy expenditure pathways, with leptin regulating energy balance due to its function as an inhibitor of hunger, and adiponectin modulating glucose levels and fatty acid breakdown. We observed higher leptin concentrations within the prenatally stressed male plasma, and lower expression of leptin (OB) and adiponectin (ADIPOQ) genes from the epididymal fat pads. We suggest that elevated leptin in the plasma elicited a negative feedback effect on OB expression levels, decreasing their quantification compared to control animals. Further analysis will include plasma quantification of insulin and glucose, as well as expression of ghrelin, a peptide which acts on the central nervous system and the bodys perception of hunger

Estrous Cyclicity of Mice During Simulated Weightlessness

Hindlimb unloading (HU) is a rodent model system used to simulate weightlessness experienced in space. However, some effects of this approach on rodent physiology are under-studied, specifically the effects on ovarian estrogen production which drives the estrous cycle. To resolve this deficiency, we conducted a ground-based validation study using the HU model, while monitoring estrous cycles in 16-weeks-old female C57BL6 mice. Animals were exposed to HU for 12 days following a 3 day HU cage acclimation period, and estrous cycling was analyzed in HU animals (n22), normally loaded HU Cage Pair-Fed controls (CPF; n22), and Vivarium controls fed ad libitum (VIV; n10). Pair feeding was used to control for potential nutritional deficits on ovarian function. Vaginal cells were sampled daily in all mice via saline lavage. Cells were dried and stained with crystal violet, and the smears evaluated using established vaginal cytology techniques by two individuals blinded to the animal treatment group. Estrous cyclicity was disrupted in nearly all HU and CPF mice, while those maintained in VIV had an average normal cycle length of 4.8 0.5 days, with all stages in the cycle visibly observed. CPF and HU animals arrested in the diestrous phase, which precedes the pre-ovulatory estrogen surge. Additionally, infection-like symptoms characterized by vaginal discharge and swelling arose in several HU animals, which we suspect was due to an inability of these mice to properly groom themselves, andor due to the change in the gravity vector relative to the vaginal opening, which prevented drainage of the lavage solution. Pair-feeding resulted in similar weight gains of HU and CPF (1.5 vs 3.0, respectively). The current results indicate that pair-feeding controlled weight gain and that the HU cage alone influenced estrous cyclicity. Thus, longer acclimation needs to be tested to determine if and when normal estrous cycling resumes in non-loaded mice in HU cages prior to HU testing. Future studies might also examine whether modifications to the vaginal lavage procedure might prevent the onset of the infection-like symptoms, and allow estrous cyclicity to be measured in this model system

Developmental Research in Space: Predicting Adult Neurobehavioral Phenotypes via Metabolomic Imaging

As human habitation and eventual colonization of space becomes an inevitable reality, there is a necessity to understand how organisms develop over the life span in the space environment. Microgravity, altered CO2, radiation and psychological stress are some of the key factors that could affect mammalian reproduction and development in space, however there is a paucity of information on this topic. Here we combine early (neonatal) in vivo spectroscopic imaging with an adult emotionality assay following a common obstetric complication (prenatal asphyxia) likely to occur during gestation in space. The neural metabolome is sensitive to alteration by degenerative changes and developmental disorders, thus we hypothesized that that early neonatal neurometabolite profiles can predict adult response to novelty. Late gestation fetal rats were exposed to moderate asphyxia by occluding the blood supply feeding one of the rats pair uterine horns for 15min. Blood supply to the opposite horn was not occluded (within-litter cesarean control). Further comparisons were made with vaginal (natural) birth controls. In one-week old neonates, we measured neurometabolites in three brain areas (i.e., striatum, prefrontal cortex, and hippocampus). Adult perinatally-asphyxiated offspring exhibited greater anxiety-like behavioral phenotypes (as measured the composite neurobehavioral assay involving open field activity, responses to novel object, quantification of fecal droppings, and resident-intruder tests of social behavior). Further, early neurometabolite profiles predicted adult responses. Non-invasive MRS screening of mammalian offspring is likely to advance ground-based space analogue studies informing mammalian reproduction in space, and achieving high-priority multigenerational research that will enable studies of the first truly space-developed mammals

Foster youth’s educational challenges and supports: Perspectives of teachers, foster parents, and former foster youth

Research indicates that children in foster care are more likely than their non-foster care peers to be absent from school, have special education needs, and to experience traumatic life events. In turn, they are also less likely to graduate high school and to attend/graduate from college. The current study, which builds on this literature and was guided by an ecological framework, employed thematic analysis to explore Massachusetts foster youth’s academic challenges and supports through interviews with teachers (n = 19), foster parents (n = 14), former foster youth (n = 12), and three individuals who were both teachers and foster parents. All three groups of participants noted that strained relationships between foster youth and their schools contributed to academic challenges. In addition, foster parents and teachers described challenges within the school/home relationship. Participants offered insights into how foster youth can be supported academically (e.g., support for foster parents navigating special education services, enhancing extracurricular opportunities). Significantly, many of their suggestions are in fact already available, suggesting that increased awareness of and utilization of these resources have the potential to increase positive outcomes for foster youth

You try to be superman and you don\u27t have to be : Gayadoptive fathers\u27 challenges and tensions in balancing work and family

A body of literature has emerged that focuses on work-family balance among heterosexual fathers. Little attention has been paid to how gay fathers balance work and family, despite the reality that they too are likely affected by similar masculine norms. The current qualitative study of 70 gay adoptive fathers (35 couples) begins to fill this gap in the literature. Analyzing interview data through the lens of Voydanoff\u27s (2005) work-family fit and balance model, we examine the ways in which gay men\u27s experiences of work-family balance are both constrained and enhanced by particular demands and resources. Highlighting the role of gender and sexual orientation, we analyze the challenges these men face and the strategies they use to cope with work-family tensions. © 2012 by the Men\u27s Studies Press, LLC.

Lesbian, gay, and heterosexual adoptive parents’ perceptions of inclusivity and receptiveness in early childhood education settings

Little research has examined the experiences of lesbian/gay (LG) parent families or adoptive parent families in early childhood education settings. This study uses interview data to examine the perceptions and experiences of 45 lesbian, gay, and heterosexual couples (90 individuals) with 10 adopted children with respect to their (1) openness with schools and teachers regarding their child’s adoptive status, racial background, and LG–parent family status and (2) perceptions of school inclusivity and responsiveness with respect to adoption, race, and family structure. The majority of parents explicitly disclosed their adoptive and LG–parent family status with teachers, but few discussed children’s racial background with teachers. Many parents viewed their children’s schools and teachers as explicitly inclusive of all types of families, providing specific examples of teacher practices that they appreciated. Some parents viewed schools as tolerant but not explicitly inclusive; reactions to this approach varied, with some parents appreciating not being “singled out,” and others feeling overlooked. Finally, some parents viewed schools as marginalizing toward their family’s adoptive, LG–parent family, and multiracial status. Lesbian mothers tended to report less positive impressions of schools than gay fathers. Findings have implications for schools and teachers seeking to create an inclusive environment for diverse families
