Experiences of reproductive genetic counselors with abortion regulations in Ohio.

Since 2010, Ohio legislators have passed more than 15 legislative changes related to abortion and abortion providers, and nine procedural abortion clinics have closed. We investigated reproductive genetic counselors' perceptions, attitudes and self-reported practices regarding Ohio's current and proposed abortion regulations. We conducted five focus groups and two telephone interviews in 2019-2020, with a total of 19 reproductive genetic counselors. Participants discussed difficulties keeping current on abortion legislation and clinics' and hospitals' policies, resulting in anticipatory anxiety and leading to additional work to discuss the laws with patients. Participants articulated that practices of reproductive genetic counseling-and patient advocacy-are impeded by the legislation. Genetic counselors perceive negative impacts on patients' autonomy, particularly reflective of healthcare disparities of marginalized groups, which may contribute to frustration and anger. Ultimately, the mental and emotional burden on genetic counselors created by abortion legislation contributes to compassion fatigue and burnout. Our findings show that Ohio's abortion regulations negatively impact reproductive genetic counselors and their relationships with their patients. Repealing existing abortion regulations and preventing future restrictive legislation may ameliorate the negative effects of regulations on reproductive genetic counselors and their patients. In the event that these laws remain, innovative communication tools and proactive professional society advocacy are potential means to mitigate the negative impact on reproductive genetic counselors.

Cervix Stromal Cells and the Progesterone Receptor A Isoform Mediate Effects of Progesterone for Prepartum Remodeling.

The prepartum transition from a soft to ripening cervix is an inflammatory process that occurs well before birth when systemic progesterone is near peak concentration. This 2-part study first determined that stromal fibroblasts but not macrophages in the cervix have progesterone receptors (PRs). Neither the number of PR cells in cervix sections nor the relative abundance or ratio of nuclear PR isoforms (PR-A/PR-B) were diminished in mice between day 15 of pregnancy and term. Second in mice lacking PR-B ( Pgrtm20mc), the number of cells that expressed the PR-A isoform were maintained during this period of prepartum cervix remodeling. Thus, progesterone effects to sustain pregnancy, as well as soften and ripen the cervix, are mediated by a stable stromal cell population that expresses PR-A and, through interactions with resident macrophages, are likely to mediate inflammatory ripening processes in preparation for birth.

Utility of Optical Density of Picrosirius Red Birefringence for Analysis of Cross-Linked Collagen in Remodeling of the Peripartum Cervix for Parturition.

We report on development of a rapid, quantitative analysis technique of collagen fibers in cross-linked structures to assess remodeling of the cervix during the transition from soft to ripening in preparation for birth. Optical density analysis of picrosirius red stain tissue using circular polarized birefringence light from fixed paraffin-embedded or frozen cervix from pregnant mice during phases of remodeling prior to birth. Data were analyzed using NIH Image J and extended recently to include studies of prepartum cervix in peripartum women. Our results, developed a rapid, consistent, technique to quantify cervical organization. This approach assesses the structure of collagen organization (the principle component of the cervix) and is essential for analysis of experimental outcomes that disrupt cervical morphology in rodent models of preterm birth. The technique, in this report has, for the first time permitted rapid, accurate assessment of the stages that define cervical ripening with large numbers of slides from individual animals. The approach integrates analysis of collagen organization, with distensability and inflammation, processes associated with cervical change before birth. This analysis further holds promise to evaluate other tissues, but also fibrolytic and fibrogenic changes in collagen associated with physiological or pathophysiological conditions.

Progesterone Receptor-Mediated Actions Regulate Remodeling of the Cervix in Preparation for Preterm Parturition.

This study determined whether a progesterone (P) receptor (PR)-mediated mechanism regulates morphological characteristics associated with prepartum cervix remodeling at term and with preterm birth. With focus on the transition from a soft to ripe cervix, the cervix stroma of untreated controls had reduced cell nuclei density/area and less organized extracellular collagen, while the density of macrophages/area, but not neutrophils, increased just 2 days before birth (day 17 vs day 15 or 16.5 postbreeding). Preterm birth was induced within 24 hours of treatment on day 16 postbreeding with PR antagonist or ovariectomy (Ovx). Pure or mixed PR antagonists increased the density of macrophages in the cervix within 8 hours (day 16.5 postbreeding), in advance of preterm birth. However, neither PR antagonists nor P withdrawal after Ovx affected the densities of cell nuclei and neutrophils or extracellular collagen compared to the same day controls-an indication that the cervix was sufficiently remodeled for birth to occur. To block the effect of systemic P withdrawal, Ovx pregnant mice were given a PR agonist, either pure or mixed. These treatments forestalled preterm birth and prevented further morphological remodeling of the cervix. The resulting increase in macrophage density in cervix stroma following Ovx was only blocked by a pure PR agonist. These findings support the hypothesis that inflammatory processes in the prepartum cervix that include residency of macrophages, cellular hypertrophy, and extracellular collagen structure are regulated by genomic actions of PR in a final common mechanism both at term and with induced preterm birth.
