[Introduction] Organ fibrosis represents a substantial a major contributor to global disease burden, implicated in over 30% of cases leading to disability-associated and fatal conditions. Among these conditions, idiopathic pulmonary fibrosis (IPF) stands as a progressive and frequently fatal interstitial lung disease characterized by aberrant extracellular matrix deposition and parenchymal scarring. The prognosis for IPF patients is poor, with a median survival time of just 3–5 years (Bhattacharya and Ramachandran, 2023; Lederer and Martinez, 2018, Ma et al., 2024, Wei et al., 2024). Current FDA-approved therapeutics, Pirfenidone and Nintedanib, demonstrate capacity to attenuate functional decline in pulmonary fibrosis but remain …

Effect Of Pre-Treatment Lab-Based Comorbidities On Treatment Related Outcomes Among Patients With Cancer, Jeffrey Alan Franks

All ETDs from UAB

Cancer is one of the leading causes of mortality and morbidity in the United States. In addition to their cancer, nearly 50% of individuals have a comorbid condition. This adds complexity to the treatment of these patients as it may delay cancer diagnosis or treatment or prevent treatment all together. Lab-values are an important tool to measure comorbidities and end-organ damage as they are routinely captured as part of standard of care and the basis of clinician decision making. However, despite the widespread multimorbidity and how crucial they are to decision making, few studies assess the association of lab abnormalities …

The Impact Of Transportation Insecurity On No-Show Appointments And Acute Care Utilization In Pediatric Sickle Cell Patients, Seabrook Hannah Jeffcoat

All ETDs from UAB

Sickle cell disease (SCD) patients experience high levels of transportation insecurity. Missed or delayed medical care due to transportation barriers can result in worsened clinical outcomes and increased hospital admissions and emergency department (ED) visits. We hypothesized that the relationship between transportation insecurity and acute care utilization is partially mediated by no-show appointments. This retrospective cohort study included 101 SCD patients aged ≤ 21 treated through the Pediatric Sickle Cell Clinic at Children’s of Alabama (COA) hospital from 2023 to 2024 and completed a social determinants of health (SDoH) questionnaire. Negative binomial or Poisson regression was used to model ED …

Micro/Nanoplastics And Cancer: Focus On Gastrointestinal Malignancies - A Narrative Review, Sana Rabeeah, Priyata Dutta, Ahmad Mahdi, Alejandra Vargas, Edward C. Oldfield, David A. Johnson

Department of Medicine Faculty Publications

Micro- and nanoplastics (MNPs) are plastic particles smaller than 5 mm and 1 μm, respectively, and are emerging environmental pollutants with growing implications for human health. These particles stem from either 'primary sources', such as intentionally manufactured microbeads and industrial abrasives, or 'secondary sources', where larger plastic items break down into smaller fragments over time. Human exposure primarily occurs through ingestion and inhalation, with contaminated seafood and plastic-laden food packaging representing key routes of entry. Once ingested, MNPs can cross the intestinal barrier, accumulate in gastrointestinal (GI) tissues, and trigger biological responses. Mechanistic studies reveal that MNPs induce oxidative stress, …

Pediatric Cancer Incidence, Temporal Trends, And Mortality In The United States By Health Disparities Indicators, Seer (1973-2014), Prachi P. Chavan, Laurens Holmes Jr.

Epidemiology, Biostatistics, & Environmental Health Faculty Publications

Background: Pediatric cancer incidence has been increasing in the United States, despite improvement in pediatric cancer survival. This steady increase in incidence trends is not completely understood but maybe associated with social and environmental factors. In this study we aimed to assess the cumulative incidence, temporal trends, and mortality rates in pediatric cancer. Additionally, we examined sub-group variability in both incidence and mortality rates. Methods: Data from Surveillance, Epidemiology, and End Results (SEER) −18 from 1973–2014 were used for the purpose of analysis in this study. Age-adjusted incidence rates were used to assess temporal trends in cancer among children aged < 1–19 years. Univariable and multivariable binomial regression models were used to examine the association between race and cancer mortality while adjusting for potential confounders. Results: There were 92,594 cancer diagnoses during this period. White children comprised 74,758, (80.7%), black children 10,030, (10.8%), and other races 6648, (7.2%). Overall the age-adjusted cumulative incidence was slightly higher among white children (16.4%) than black children (12.4%) and other (13.0%). Children aged 15–19 years and those in metropolitan regions were more likely to be diagnosed with pediatric cancer. Relative to females, males were 16% more likely to die from the disease [adjusted Risk Ratio (aRR): 1.16, 95% Confidence Interval (CI): 1.09–1.22]. Additionally, compared to white children, black children had higher mortality rates [(aRR): 1.37, 99% CI: 1.23–1.52]. Conclusions: There is an increasing trend in pediatric cancer incidence; while white children have the highest incidence, black children and males indicated a survival disadvantage, indicative of racial and sex variability in overall pediatric cancer in the United States.

Epidemiological Principles In Claims Of Causality: An Enquiry Into Repetitive Head Impacts (Rhi) And Chronic Traumatic Encephalopathy (Cte), Lauren V. Fortington, J. David Cassidy, Rudolph J. Castellani, Andrew J. Gardner, Andrew S. Mcintosh, Michael Austen, Zachary Yukio Kerr, Kenneth L. Quarrie

Research outputs 2022 to 2026

Determining whether repetitive head impacts (RHI) cause the development of chronic traumatic encephalopathy (CTE)-neuropathological change (NC) and whether pathological changes cause clinical syndromes are topics of considerable interest to the global sports medicine community. In 2022, an article was published that used the Bradford Hill criteria to evaluate the claim that RHI cause CTE. The publication garnered international media attention and has since been promoted as definitive proof that causality has been established. Our counterpoint presents an appraisal of the published article in terms of the claims made and the scientific literature used in developing those claims. We conclude that …
