Exploring Social Impairment In Those With Opioid Use Disorder: Linking Impulsivity, Childhood Trauma, And The Prefrontal Cortex, Thais Costa Macedo De Arruda, Laura Sinko, Paul Regier, Altona Tufanoglu, Adrian Curtin, Anne M. Teitelman, Hasan Ayaz, Peter F. Cronholm, Anna Rose Childress

College of Nursing Faculty Papers & Presentations

BACKGROUND: Challenges with social functioning, which is a hallmark of opioid use disorder (OUD), are a drawback in treatment adherence and maintenance. Yet, little research has explored the underlying mechanisms of this impairment. Impulsivity and corresponding neural alterations may be at the center of this issue. Childhood adversity, which has been linked to both impulsivity and poorer treatment outcomes, could also affect this relationship. This study explores the relationship between impulsivity, social functioning, and their neural correlates in the prefrontal cortex, while examining the potential moderating effects of childhood trauma in individuals recovering from OUD.

Markers Of Growth And Nutrition In Children With Acquired Chylothorax Post Chd Surgery, Kevin N. Marzotto, Karin R. Videlefsky, Meghan P. Howell, Thomas R. Kimball, Frank A. Pigula, Kurt D. Piggott

School of Medicine Faculty Publications

Background: Acquired chylothorax is an established complication of CHD surgery, affecting 2-9% of patients. CHD places a child at risk for failure to thrive, with subsequent chylothorax imposing additional risk. Objective: We conducted a retrospective chart review to ascertain quantitative markers of nutrition and growth in children affected by chylothorax following CHD surgery between 2018 and 2022 compared to controls. Methods: We utilised electronic medical record system, EPIC, at Children's Hospital, New Orleans, targeting subjects < 18 years old who underwent CHD surgery between 2018 and 2022 and developed a subsequent chylothorax. Study subjects were identified using the 10th revision of the International Classification of Diseases codes (ICD-10 codes: J94.0, I89.8, and J90.0). Each chylothorax case (n = 20) was matched by procedure type and age to a control with no chylothorax (n = 20). Data were recorded in REDCap and analysed using SPSS. Results: After removal of outliers, we analysed 19 total matched pairs. There was no statistical difference in growth velocity (p = 0.12), weight change (operation to discharge) (p = 0.95), weight change (admission to discharge) (p = 0.35), Z-score change (operation to discharge) (p = 0.90), Z-score change (admission to discharge) (p = 0.21), serum protein (p = 0.88), or serum albumin (p = 0.82). Among cases, linear regression demonstrated no significant association between maximum chylous output and growth velocity (p = 0.91), weight change (operation to discharge) (p = 0.15), or weight change (admission to discharge) (p = 0.98). Conclusions: We did not observe statistically significant markers of growth or nutrition in children with chylothorax post-CHD surgery compared to those without chylothorax. Multisite data collection and analysis is required to better ascertain clinical impact and guide clinical practice.

Systematic multi-omics analysis revealed ancestry-dependent molecular alterations, but their impact on the efficacy of anti-cancer treatment is yet largely unknown. Here, we analyzed clinical trials from ClinicalTrials.gov and found that only 8,779/102,721 (8.5%) oncology clinical trials posted information on enrollment by race/ethnicity. The underrepresentation of non-White populations suggests that it remains challenging to determine differences in the efficacy of anti-tumor treatments among different racial groups. Through a comprehensive analysis of clinically actionable genes, imputed drug responses, and immune features, we identified potential differences in treatment response to targeted, chemo and immunotherapies between different ancestral populations. Further analysis of multiple independent …

Adult type ovarian granulosa cell tumors (AGCT) are rare malignancies with the near universal c.C402G (p.Cys134Trp) somatic mutation in FOXL2, a forkhead box family transcription factor important for ovarian function. Relapsed AGCT is incurable, but the mechanism of the unique FOXL2 mutation could confer therapeutic vulnerabilities. To identify FOXL2C134W-dependent pharmacologic synergies, we created and characterized endogenous FOXL2 isogenic AGCT cells and an AGCT tumoroid biobank. A drug screen identified that glucocorticoids promote FOXL2C134W-dependent AGCT growth. Epigenetic investigation revealed that the Cys134Trp mutation exposes latent DNA sequence-specific chromatin remodeling activity in FOXL2. FOXL2C134W-dependent chromatin remodeling activity redirected glucocorticoid receptor chromatin occupancy …

A Novel Sensitivity Maximization At A Given Specificity Method For Binary Classifications, Seyyed Mahmood Ghasemi, Chunhui Gu, Johannes F Fahrmann, Samir Hanash, Kim-Anh Do, James P Long, Ehsan Irajizad

Faculty, Staff and Student Publications

In the cancer early detection field, logistic regression (LR) is a frequently used approach to establish a combination rule that differentiates cancer from noncancer. However, the application of LR relies on a maximum likelihood approach, which may not yield optimal combination rules for maximizing sensitivity at a clinically desirable specificity and vice versa. In this article, we have developed an improved regression framework, sensitivity maximization at a given specificity (SMAGS), for binary classification that finds the linear decision rule, yielding the maximum sensitivity for a given specificity or the maximum specificity for a given sensitivity. We additionally expand the framework …

Evaluating Performance Of The Pre-Eclampsia Integrated Estimate Of Risk-Machine Learning (Piers-Ml) Model In A Kenya Cohort Of Women With Pre-Eclampsia, Felix Mogire Nyagaka

Master of Medicine in Obstetrics and Gynecology

Introduction 

Pre-eclampsia is a leading cause of significant maternal morbidity and mortality and complicates approximately 2%-4% of all pregnancies. Delivery is the only known definitive treatment. Pre-eclampsia can have unpredictable progression with sudden deterioration leading to severe adverse outcomes.

Currently, no adverse maternal risk prediction model is validated for use in sub-Saharan Africa. The new Pre-Eclampsia Integrated Estimate of Risk Machine Learning (PIERS-ML) model identifies women with pre-eclampsia who are at the lowest and greatest risk of severe adverse maternal outcomes within 48 hours of initial assessment and informs their care. Whereas, it has been validated for use in high …

Correlation Between Fetal Abdominal Wall Adiposity And Neonatal Outcomes, Elaine Murugi Nyaga

Dual reporters encoding two distinct proteins within the same mRNA have had a crucial role in identifying and characterizing unconventional mechanisms of eukaryotic translation. These mechanisms include initiation via internal ribosomal entry sites (IRESs), ribosomal frameshifting, stop codon readthrough and reinitiation. This design enables the expression of one reporter to be influenced by the specific mechanism under investigation, while the other reporter serves as an internal control. However, challenges arise when intervening test sequences are placed between these two reporters. Such sequences can inadvertently impact the expression or function of either reporter, independent of translation-related changes, potentially biasing the results. …
