Implications of Social Determinants of Health Characteristics on Fetal Growth Restriction Among Various Racial/Ethnic Groups.

OBJECTIVES: Current knowledge regarding the relationship between social determinants of health (SDOH) characteristics of hospitalized American pregnant women and fetal growth restriction (FGR) reveals a dearth in the literature. Therefore, we examined the impact of SDOH on FGR among hospitalized American women in this study. METHODS: Using the Nationwide Inpatient Sample (NIS) dataset for the years 2016-2018, we conducted this cross-sectional study. We conducted survey logistic regression to examine the association between SDOH factors and FGR, after adjusting for various hospitalization characteristics. RESULTS: Non-Hispanic (NH)-Black people had the highest prevalence of SDOH issues (0.7%), followed by Hispanics who had a prevalence of 0.4%. We observed that pregnant women with SDOH issues were 1.16 times as likely to experience FGR as those without SDOH (95% CI 1.0-1.34). When compared to their respective racial counterparts without SDOH, Hispanics with SDOH had increased odds, NH-White and NH-others with SDOH had the same likelihood, and NH-Black women with SDOH had lower odds of FGR. CONCLUSIONS FOR PRACTICE: Overall, our study illustrated an association between maternal SDOH issues and FGR, and the impact of SDOH issues on the outcome of FGR across various racial/ethnic groups. While our study provides useful insight into the topic, further research is needed to explain the observed varied influence of SDOH on FGR across racial/ethnic groups.

What is already known on this subject? Children with fetal growth restriction (FGR) present with a greater risk of long-term health effects including impaired neurological, cardiovascular and endocrine diseases in adulthood. FGR affects 5-10% of pregnancies and is the second leading cause of perinatal mortality.What this study adds? An association between maternal social determinants of health (SDOH) issues and FGR, and the impact of SDOH issues on the outcome of FGR across various racial/ethnic groups is present. When compared to their respective racial counterparts without SDOH, Hispanics with SDOH had increased odds of FGR.

Racial and insurance status disparities in imaging modality among pediatric patients diagnosed with appendicitis.

BACKGROUND: Studies have assessed the type of diagnostic imaging used in the treatment of appendicitis in children. Few studies investigated racial/ethnic and insurance disparities in imaging modalities used in pediatric patients diagnosed with appendicitis. Our study seeks to determine whether race/ethnicity and insurance status are associated with imaging modality chosen for pediatric patients diagnosed with appendicitis in the emergency department. METHODS: This was a retrospective cohort study utilizing data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from 2010 to 2019. We included children <18 years old with a ICD-9-CM and ICD-10-CM diagnosis of appendicitis. Exposures were patient race/ethnicity and insurance status. Outcome of interest was imaging modality. We conducted adjusted survey logistic regression to evaluate the patient characteristics and receipt each of the imaging modalities among those with a diagnosis of appendicitis. RESULTS: Of 308,140,115 emergency department (ED) visits, 1,126,865 (0.37%) had a diagnosis of appendicitis. Overall, male patients were more likely to receive CAT scan in comparison to female children (OR=2.52, 95% CI= 1.16-5.49). Additionally, Hispanic children who had significantly greater odds of obtaining ultrasound (OR= 4.56, 95% CI=1.09-19.12). Hispanic children were also less likely to receive x-ray (OR= 0.31, 95% CI=0.11-0.89) or computed tomography (CT) scans (OR= 0.23, 95% CI=0.07-0.76). Children diagnosed with appendicitis who had insurance other than private, Medicare, Medicaid, or self-pay were significantly more likely to receive x-ray studies (OR=4.39, 95% CI= 1.23-15.69). CONCLUSIONS AND GLOBAL HEALTH IMPLICATIONS: This study demonstrated the presence of racial/ethnic and insurance status disparities in the imaging modality chosen to assist in diagnosing appendicitis in pediatric patients.

Genetic Pathways of Neuroregeneration in a Novel Mild Traumatic Brain Injury Model in Adult Zebrafish.

Mild traumatic brain injuries (mTBIs) are one of the most prevalent neurological disorders, and humans are severely limited in their ability to repair and regenerate central nervous system (CNS) tissue postinjury. However, zebrafish (Danio rerio) maintain the remarkable ability to undergo complete and functional neuroregeneration as an adult. We wish to extend knowledge of the known mechanisms of neuroregeneration by analyzing the differentially expressed genes (DEGs) in a novel adult zebrafish model of mTBI. In this study, a rodent weight drop model of mTBI was adapted to the adult zebrafish. A memory test showed significant deficits in spatial memory in the mTBI group. We identified DEGs at 3 and 21 days postinjury (dpi) through RNA-sequencing analysis. The resulting DEGs were categorized according to gene ontology (GO) categories. At 3 dpi, GO categories consisted of peak injury response pathways. Significantly, at 21 dpi, GO categories consisted of neuroregeneration pathways. Ultimately, these results validate a novel zebrafish model of mTBI and elucidate significant DEGs of interest in CNS injury and neuroregeneration.
