RESUMO
BACKGROUND: Victims of intimate partner violence (IPV) during pregnancy experience significant physical and mental health consequences and adverse birth outcomes. Our objective was to describe the prevalence of IPV, and risk factors associated with IPV in pregnant, rural Guatemalan women. METHODS: This retrospective cohort study was completed using quality improvement data gathered during routine prenatal health visits to women of Trifinio, Guatemala, by the Madres Sanas maternal health program from 2018 through 2020. Chi-square and t-tests were used to determine if there were differences in characteristics between women who self-reported experiencing IPV and those who did not. If differences occurred (p < 0.2), those covariates were included in a multivariable logistic regression to determine sociodemographic risk associated with IPV. RESULTS: 583 women were enrolled with Madres Sanas between October 10, 2018, and October 1, 2020, and reported on IPV. Nineteen (3.26%) women reported experiencing IPV. The highest prevalence of IPV (7.6%) occurred in the sub-group of women who experienced food insecurity during the past year. The sole covariate of all sociodemographic and health characteristics which differed significantly between women who reported experiencing and not experiencing IPV was food insecurity. A regression model found that those who had worried about ability to buy food in the past year had a 3.19-fold increase in the odds that they experienced IPV (95% CI 1.072, 9.486, p-value 0.037). CONCLUSION: Among this convenience sample of women, the prevalence of IPV was 3.26%. Food insecurity was associated with increased odds of experiencing IPV, highlighting an opportunity for interventions.
RESUMO
BACKGROUND: Transcription factor AP-2alpha has been implicated as a cell-type-specific regulator of gene expression during vertebrate embryogenesis based on its expression pattern in neural crest cells, ectoderm, and the nervous system in mouse, chick, and frog embryos. AP-2alpha is prominently expressed in cranial neural crest cells, a population of cells migrating from the lateral margins of the neural folds during closure of the neural tube in E (embryonic day of development) 8-9 mouse embryos. Homozygous AP-2alpha mutant mice die perinatally with cranio-abdominoschisis, full facial clefting, and defects in cranial ganglia and sensory organs. METHODS: Mice heterozygous for the AP-2alpha mutation on a 129/Sv strain were crossed with wildtype mice from the strain 129/Ola. The resulting embryos were genotyped, examined and used for histological analysis. RESULTS: A subset of animals heterozygous for the AP-2alpha mutation develop a midbrain exencephaly after the mutation was crossed for one generation in the 129/Ola mouse strain. Up to 14% of the animals show a failure of the cranial neural folds to close resulting in a partial exencephaly, all of them being heterozygous for the mutation. The affected animals show reduced rostrocaudal dimensions of the skull and malformations of the bones of the cranial vault. The neural tube defects vary from pure midbrain exencephaly to a forebrain/midbrain exencephaly where the proliferating neural tissue covers the eyes completely. CONCLUSIONS: The results support a role of AP-2alpha in the etiology of exencephalic disorders. The phenotype observed might be due to a downregulation of the remaining allele suggesting the presence of an upstream modifier gene.
