Background: Black, Indigenous, and people of color (BIPOC) families comprise a disproportionately low percentage of home and freestanding birth center births in New Mexico (NM), despite NM Medicaid coverage of care by Licensed Midwives (LMs) in these settings. The purpose of this study was to examine why low income BIPOC seek out LM care, how they benefit from this model of care, and which factors facilitate and obstruct access.

Methods: We conducted 7 focus groups with 55 low income BIPOC individuals who had birthed in New Mexico in the past 5 years.

It has been demonstrated that helminths are capable of critically impacting the fitness of their hosts. This has typically been shown experimentally through the administration of anthelmintic drugs but are rarely performed on a landscape or host population scale. Here, the anthelmintic fenbendazole (FBZ) was mixed in a supplemental feed and provided to a free-ranging population of Northern bobwhite quail ().

Article Synopsis
  • Full-grown mammalian oocytes exposed to moderate to severe DNA damage show ineffective DNA damage repair (DDR), leading to conditions like aneuploidy due to altered chromatin states and inaccessible repair proteins.* -
  • Mouse and pig oocytes do not activate autophagy in response to DNA damage like somatic cells do, which contributes to their impaired DDR and potentially explains the chromatin alterations.* -
  • Reduced autophagy is notably pronounced in aged oocytes with severe DNA damage and is linked to improved DNA repair, suggesting enhancing autophagy could benefit assisted reproductive technologies for women with lower oocyte quality.*
