Understanding medication abortion ineligibility due to gestational age among a cohort of patients in Southern California.

Objective: Medication abortion (MAB) is safe and effective up to 77 days gestation. Limited data are available on how often patients are ineligible for MAB due to advanced gestational age and how many of those ineligible go on to receive procedural abortion.

Study Design: Retrospective analysis of electronic health records from Planned Parenthood of the Pacific Southwest (PPPSW) from January - December 2021.

Preconception care utilization: Self-report versus claims-based measures among women with Medicaid.

The objective of this study is to compare self-reported preconception care utilization (PCU) among Medicaid-covered births to Medicaid claims. We identified all Medicaid-covered births to women ages 15-45 in 26 states in the year 2012 among the Pregnancy Risk Assessment and Monitoring System (PRAMS) survey and Medicaid Analytic eXtract (MAX) claims data, and identified preconception services in the latter using diagnosis codes published by Health and Human Services' Office of Population Affairs. We fit mixed-effects logistic regression models for the probability of PCU on sociodemographic factors (age, race, and ethnicity) and clinical diagnoses (depression, diabetes, or hypertension), separately for each dataset.

Identification of genetic drivers of plasma lipoprotein size in the Diversity Outbred mouse population.

Despite great progress in understanding lipoprotein physiology, there is still much to be learned about the genetic drivers of lipoprotein abundance, composition, and function. We used ion mobility spectrometry to survey 16 plasma lipoprotein subfractions in 500 Diversity Outbred mice maintained on a Western-style diet. We identified 21 quantitative trait loci (QTL) affecting lipoprotein abundance.

Genetic Analysis of Obesity-Induced Diabetic Nephropathy in BTBR Mice.

Diabetic nephropathy (DN) is the leading cause of end-stage renal disease in the U.S. and has a significant impact on human suffering.

Missense variants in SORT1 are associated with LDL-C in an Amish population.

Common noncoding variants at the human 1p13.3 locus associated with SORT1 expression are among those most strongly associated with low-density lipoprotein cholesterol (LDL-C) in human genome-wide association studies. However, validation studies in mice and cell lines have produced variable results regarding the directionality of the effect of SORT1 on LDL-C.
