Reducing Stress Through Low-Carbohydrate Nutrition Education In Emergency Department Staff – A Quality Improvement Project, Hassan Oman Gomar

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction and Background

Emergency department staff often face job-related stress, which can lead to burnout, reduced compassion satisfaction, and adverse effects on patient care. Loma Linda University Health (LLUH) offers support programs, including Care for the Caregiver (C4C) and the Living Whole Employee Wellness program, that provide emotional and general wellness resources. While these programs are helpful, they do not offer practical solutions for everyday stress. There is a need for simple, lasting, and food-based ways to help staff manage stress and perform better. Recent research shows that eating patterns, especially high intake of processed carbohydrates, can alter energy and …

Neonatal Admissions And Mortality: A Statistical Adjustment Approach Using Birthweight-Specific Curves To Address Bias Due To Underreporting In 65 Hospitals In Four African Countries, Lucas Malla, Siu Wong, Samuel Ngwala, Evelyn Zimba, Msandeni Chiume, Norman Lufesi, Kondwani Kawaza, Honorati Masanja, Josephine Shabani, William Macharia

Paediatrics and Child Health, East Africa

Background Underreporting of neonatal admissions and deaths – particularly among <  1000 g newborns – compromises the plausibility of in-patient neonatal mortality rate (iNMR) estimates. This limits progress tracking, since 2.3 million neonatal deaths occur annually, and 65 countries are projected to miss the Sustainable Development Goal (SDG) 3.2 target of fewer than 12 deaths per 1000 live births by 2030. Reliable iNMR estimates are essential for national and hospital-level monitoring. This study assessed birthweight-specific adjustment curves developed using simulated data, and extended the approach to routine data from 172,809 neonatal admissions across four African countries in the NEST360 network.

Methods Simulated data were generated using birthweight intervals of 500 g from 500 to 5000 g, with 1000 values per category representing 1000 hospitals. Admissions were drawn from a negative binomial distribution and mortality rates from a beta distribution based on published birthweight-specific iNMRs. Adjustment functions were developed using data from 500 hospitals without underreporting and tested on 500 with induced underreporting. This approach was then extended to real data from 65 NEST360 partnering hospitals. The adjustment functions were derived from 26 hospitals with plausible reporting (iNMR ≥ 700 per …

Unlocking The Potential Of Sub-Saharan Africa In Globalized Cancer Clinical Trials: A Perspective From The 2024 Aortic-Asco Stakeholder Meeting, Abiola Ibraheem, Adedayo Joseph, Miriam Mutebi, Mansoor Saleh, Sitna Mwanzi, Olusegun Alatise

General Surgery, East Africa

Sub-Saharan Africa (SSA) remains significantly underrepresented in global cancer clinical trials, despite having the largest population of individuals of African descent, an essential demographic for ensuring diversity in clinical research. This study, developed from the 2024 African Organization for Research and Training in Cancer (AORTIC)-ASCO stakeholder meeting, addresses the critical need to involve SSA in cancer trials to improve global trial diversity and patient outcomes. Although globalization of trials has shifted research sites to regions like Eastern Europe and Asia, < 1% occur in Africa. This report highlights emerging solutions such as regional alliances, decentralized trial models, capacity-building initiatives, and public-private partnerships. The role of AORTIC and its Clinical Trial Special Interest Group in advancing training, infrastructure development, and international collaboration is discussed, with notable clinical trial networks, such as HypoAfrica, ARETTA, African Research Group for Oncology, and regional consortia, illustrating growing momentum and capability. This study advocates for a coordinated strategy to integrate SSA into global trials, ensuring more inclusive, effective, and equitable cancer treatment outcomes.

BACKGROUND: Hyper-inflammation is common to multiple critical care syndromes, including acute respiratory distress syndrome (ARDS) and sepsis, and is associated with worse outcomes. A signature of hyper-inflammatory ARDS has been described in adults using IL-6, TNFR1, and bicarbonate, and has prognostic utility. We investigated the application of this traditional parsimonious signature to pediatric ARDS patients and tested whether we could improve prognostic enrichment using other cytokines.

METHODS: We leveraged a prospective multicenter cohort study of 500 children with ARDS (Linking Endotypes and Outcomes in Pediatric Acute Respiratory Distress Syndrome [LEOPARDS]; NCT04113434) study. Plasma samples were obtained within 24 h of …

Background & aims: Most pediatric hepatocellular tumors are classified as hepatoblastoma (HB) or hepatocellular carcinoma (HCC), yet a subset exhibits mixed histological and molecular features. These hepatoblastomas with carcinoma features (HBCs) include cases provisionally designated as hepatocellular neoplasm-not otherwise specified (HCN-NOS). Their biology remains poorly understood, with unresolved questions about their cellular composition and outcomes. It is unclear whether HBCs comprise hybrid cells with combined HB and HCC characteristics (HBC cells) or admixtures of distinct HB and HCC cells. We characterized the biology, etiology, cellular composition, and evolutionary dynamics of HBCs.

Methods: We performed multi-omics profiling - including single-nucleus RNA …

Phase 1 trials in Brazil, Gabon, and the USA of recombinant Na-GST-1 adsorbed on Alhydrogel (Na-GST-1/Al), co-administered with or without AP 10-701 (Toll-like receptor [TLR] 4 agonist) or CpG 10104 (TLR9 agonist), showed the vaccine was well tolerated, safe, and immunogenic. A controlled human hookworm infection (CHHI) model was previously developed to evaluate the effect of candidate hookworm vaccines on infection. We aimed to assess the effect of vaccination with three different Na-GST-1 vaccine formulations on subsequent …

Hypovascular Aggressive Angiomyxoma In A Pregnant Adolescent: A Case Report And Review Of Its Multimodal Imaging Appearances, Mohammad Ghasemi-Rad, David Léon

Faculty, Staff and Students Publications

Aggressive angiomyxoma (AAM) is a rare mesenchymal tumor that primarily arises in the perineum and pelvis of young females. It is sometimes identified incidentally on pelvic examination and obstetric imaging. Although asymptomatic at small sizes, AAM is typically hypervascular and can grow large enough to complicate a patient's obstetric and gynecologic course of treatment. While AAM is a rare diagnosis reported in the literature, there are limited descriptions of its multimodal radiologic appearance, and uncommonly, it can present as a hypovascular mass. We describe a rare case of hypovascular AAM in pregnancy that did not respond favorably to targeted embolization, …

Obsessive-compulsive disorder (OCD) is an impairing mental health condition that affects individuals across the lifespan. Some literature has evaluated mental health stigma in adults with OCD but limited attention has been given to youth, as well as those of Latino ancestry. The present study reported the extent of stigma experiences among Latin American youth with OCD, as well as examined sociodemographic, clinical and psychological correlates. 235 youth with clinician confirmed diagnoses of OCD from 10 North and South American countries completed questionnaires assessing stigma experiences, symptomatology, and functioning. Sociodemographic and clinical variables were also collected. The average OCD stigma response …

Reciprocal Compensation Of Caspase-2 And P53 Regulates The Dna Damage Response In Hct116 Colon Cancer Cells, Karen Zúñiga, Sarah Wright, Lisa Bouchier-Hayes

Faculty, Staff and Students Publications

Caspase-2 has positive and negative effects on tumor growth in different cancer models. The mechanisms determining these dual outcomes of caspase-2 activation are unclear underscoring the need to assess caspase-2 function in different cell types. We report that high caspase-2 expression is associated with lower survival in patients with colon cancer and increased tumor size in HCT116 colon cancer xenografts. We investigated the interplay between caspase-2 and p53 in regulating the proliferation of these cells. While neither of these proteins had much of an effect on cell cycle arrest on their own, deficiency in both caspase-2 and p53 led to …

Maternal Separation Increases Anxiety-Like Phenotypes, Fear Responses, And Alters Bdnf Methylation In A Predator Odor Exposure Model Of Early Life Adversity, Olivia Bigham, Luke W Ayers, Jeffrey B Rosen, Tania L Roth

Faculty, Staff and Students Publications

Early life adversity (ELA) can increase incidences of psychopathology later in life, partly through aberrant expression of the brain-derived neurotrophic factor (Bdnf) gene. One mechanism whereby ELA can alter Bdnf expression is through DNA methylation, typically reducing expression. Previously, our lab has utilized a predator odor model of ELA, whereby dams with their pups are exposed to either 2,5-dihydro-2,4,5-trimethylthiazoline (TMT), a synthetic derivative of fox feces, or butyric acid (BTA) as a noxious control for the first three postnatal weeks. Developmental exposure to TMT reduced adolescent freezing to TMT, suggesting the presence of the caregiver may be buffering …

Ankyrin-B And Ankyrin-G Are Required For Synaptic Integrity In The Mouse Outer Retina, Collin Todora, Daniela Becerril, Debalina Goswami-Sewell, Rajashree Venkatraman, Cesiah C Gomez, Caitlin Bagnetto, Audrey Lee, Marlon F Mattos, Yi-Rong Peng, Mrinalini Hoon, Elizabeth Zuniga-Sanchez

Faculty, Staff and Students Publications

Retinal circuit assembly relies on the precise timing and positioning of key molecules between neuronal partners to mediate proper synapse formation. In the outer retina, horizontal cells (HCs) are important interneurons that make the first contacts with photoreceptors and begin to segregate visual information into two distinct pathways by selectively forming synapses to the different types of photoreceptors. Dendrites of HCs synapse exclusively to cone photoreceptors, whereas the axon terminal synapses to rod photoreceptors. Failure to properly form these early connections disrupts the downstream connectivity of other postsynaptic neurons and leads to abnormal visual function. Although these early events are …

Reclassifying Pediatric Nafld Using The Steatotic Liver Disease Framework: A Multicenter Retrospective Study From The Nash Crn, Kimberly P Newton, Mark H Fishbein, Jean P Molleston, Stavra A Xanthakos, Ajay K Jain, Miriam B Vos, Niviann M Blondet, Krupa R Mysore, Cynthia A Behling, Laura A Wilson, Jeffrey B Schwimmer

Faculty, Staff and Students Publications

Background and aims: The terminology for hepatic steatosis and NAFLD was revised under the umbrella of steatotic liver disease, with metabolic dysfunction-associated steatotic liver disease (MASLD) as the primary subtype. MASLD is defined by hepatic steatosis plus at least 1 cardiometabolic risk factor. A new category, Met-ALD, describes MASLD with alcohol consumption below the defined thresholds for alcohol-associated liver disease (ALD). While adult studies have demonstrated strong concordance between NAFLD and MASLD, the applicability of this framework in children remains unclear.

Approach and results: We assessed children clinically diagnosed with NAFLD and enrolled in the NASH CRN who had available …

A Comparison Of Dual Vs. Single Diagnostic Code Approaches For Neonatal Opioid Withdrawal Syndrome Surveillance In Neonates ≥ 35 Weeks Gestational Age, Marina Feffer

Biostatistics Collaborative Core: Faculty Publications and Other Works

Background

Using dual ICD-10-CM codes for exposure/withdrawal (P04.49 or P96.1, respectively) may be more sensitive for identifying Neonatal Opioid Withdrawal Syndrome (NOWS) than P96.1 alone. There are currently no studies that report on national prevalence using this dual code approach.

Objectives

We examined U.S. national NOWS prevalence trends comparing the dual vs. single code approach for surveillance.

Methods

2016–2022 cycles of cross-sectional data from the U.S. Healthcare Cost and Utilization Project, Kids’ Inpatient Database were used to estimate weighted NOWS prevalence in newborns ≥ 35 weeks excluding iatrogenic cases. Generalized linear models with predictive margins were used to estimate prevalence …

Spatially Dissecting Drivers Of Inter- And Intra-Tumoral Heterogeneity In Kenyan Breast Cancer, Mustapha Abubakar, Shahin Sayed, Hela Koka, Scott Lawrence, Karun Mutreja, Xing Hua, Petra Lenz, Samuel Anyaso-Samuel, Rosemary Kamau, Beryl Ooro

Pathology, East Africa

Despite growing evidence on the impact of intra-tumoral heterogeneity (ITH) in breast cancer (BC), its biological drivers and clinically relevant mitigation strategies remain poorly characterized, particularly in low-resource settings where spatial profiling is rarely applied. To address this gap, we conducted a comprehensive, multiplatform spatial profiling study of BC in a Kenyan population. Using the NanoString GeoMx™ Digital Spatial Profiler, we quantified 44 protein markers across 707 spatially defined, PanCK-segmented Areas of Illumination (AOIs) from 31 tumors. All tumors exhibited measurable ITH, with one-third showing marked heterogeneity. Sixteen patients exhibited two or more intrinsic subtypes within their tumors, three of …
