Changes in the treatment and outcomes of different severities of neonatal hypoxic ischemic encephalopathy in California: a retrospective cohort study.

Objective: Evaluate the changes in management and outcomes of Californian infants with hypoxic ischemic encephalopathy (HIE).

Study Design: Infants with HIE were identified from a California administrative birth cohort using ICD codes and divided into two epochs, Epoch 1 (2010-2015) and Epoch 2 (2016-2019). Risk ratios (RR) for induced hypothermia (IH) in each epoch and their outcomes were calculated using log-linear regression.

Identification of Chronic Hypertension in Pregnancy in Three Administrative Data Sources Among Medicaid-Funded Births in California.

Purpose: Administrative data sources are used to describe the epidemiology of chronic hypertension in pregnancy and its consequences. Differences in identification across sources may affect research estimates. We compared identification of chronic hypertension in birth certificate records, hospital discharge records, and Medi-Cal claims in the same individuals.

The University of California Study of Outcomes in Mothers and Infants (a Population-Based Research Resource): Retrospective Cohort Study.

Background: Population-based databases are valuable for perinatal research. The California Department of Health Care Access and Information (HCAI) created a linked birth file covering the years 1991 through 2012. This file includes birth and fetal death certificate records linked to the hospital discharge records of the birthing person and infant.

Prenatal homelessness, food insecurity, and unemployment and adverse infant outcomes in a California cohort, 2007-2020.

Objectives: Characterize the relationship between infant outcomes and prenatal homelessness, food insecurity and unemployment.

Study Design: California live births between 22- and 44-weeks' gestation comprised 6,089,327 pregnancies (2007-2020). Data were collected from linked Vital Statistics and hospital discharge records.

The Effect of Cannabis Consumption During Lactation on the Macronutrient Concentrations in Breast Milk.

Human breast milk macronutrients play a vital role in the development of breastfed infants and are known to be influenced by several factors. There is limited information on the influence of cannabis use during lactation on these macronutrients. Given the rising use of cannabis among lactating women with its widespread legalization, this study aimed to examine the association of cannabis use during lactation on breast milk macronutrients.
