Deaths Of Despair Among Cancer Survivors In Rural/Urban Appalachia (2000-2022), Jason Semprini, Anders Erickson, Nosa Osazuwa-Peters

Journal of Appalachian Health

Introduction: Rising deaths of despair (premature deaths from suicide, overdose, alcohol, and violence) in adults under age 65 persist across the United States, especially in Appalachia. People diagnosed with cancer may face elevated risks of such deaths due to pain, psychosocial distress, and financial hardship.

Purpose: Deaths of despair trends were compared among adults with cancer across Appalachian and non-Appalachian regions, stratified by sex and rurality.

Methods: Analyzing SEER-21 Incidence-Based Mortality data (2000–2022), deaths caused by suicide, cirrhosis of the liver, or accidents (includes overdose) were identified among adults aged 20–64 years. Annual mortality rates per 100,000 total population were …

There is insufficient understanding of the molecular basis of prostate cancer (PCa) across different populations. We perform a large-scale proteome-wide association study (PWAS) to identify proteins with genetically regulated expression in plasma to be associated with PCa risk across populations. We develop genetic prediction models for expression of 1578, 1993, 1218, and 1390 proteins for African (n = 450), European (n = 758), Asian (n = 289), and Hispanic/Latino (n = 474) males, respectively, and evaluate associations of genetically regulated protein expression with PCa risk in 19,391 PCa cases and 61,608 controls of African population, 122,188 cases and 604,640 controls …

‘In Texas, Everybody Wants Antibiotics’: Reducing Inappropriate Antibiotic Expectations And Use With A Provider-Patient Communication Tool In Primary Care, Ashley Collazo, Paige Wermuth, Johanan Luna Rodriguez, Kiara Olmeda, Azalia Mancera, Fabrizia Faustinella, Michael K Paasche-Orlow, Roger Zoorob, Barbara Wells Trautner, Larissa Grigoryan

Faculty, Staff and Students Publications

Background/objective: Patients often expect antibiotics for self-limiting diseases, pressuring providers to prescribe antibiotics unnecessarily. These expectations also contribute to the unsafe practice of taking antibiotics without a prescription (non-prescription use), such as pills retained from prior prescriptions or antibiotics from non-medical sources. Previous work shows that non-prescription use is due to strong, widely held misconceptions regarding the curative power of antibiotics. To reduce unnecessary use of antibiotics, we developed and pilot-tested a patient-focused, bilingual (English and Spanish) educational tool with patient and provider stakeholder input. The tool, a trifold brochure, included information on safe antibiotic use, potential antibiotic harms and …

Kimmel Cancer Center Faculty Papers

Human T-cell leukemia virus type 1 (HTLV-1), the first oncogenic human retrovirus, causes adult T-cell leukemia/lymphoma (ATLL), an aggressive neoplasm of mature CD4+ T-cells that is incurable in most patients and is associated with a median survival of less than 1 year. HTLV-1 also causes inflammatory disorders, including HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and uveitis. The estimated lifetime risks of ATLL and HAM/TSP in HTLV-1 carriers are 3-5% and 0.25-1.8%, respectively. Although there is uncertainty about other health effects of HTLV-1, a recent meta-analysis showed an association between HTLV-1 and cardiovascular, cerebrovascular, and metabolic diseases and a 57% increased risk …

Campus Research Month

Healthy plant-based eating, a health-related behavior that nurses may promote, has been associated with a decrease in multiple types of cancer. However, the association of a healthy plant-based dietary pattern with decreased female reproductive cancers has not yet been established.

This review of the literature followed PRISMA guidelines to search for the relationship between a healthy plant-based dietary pattern and incidence of and mortality from a breast or gynecological cancer diagnosis. Databases searched for this review included PubMed, EMBASE, CINAHL, and Web of Science.

We identified 27 publications that met the qualifications for inclusion. Twelve studies covered mortality from breast, …

Effects Of Smoking Behavior On Lung Metastasis In The All Of Us Research Program, Vikram R Shaw, Jinyoung Byun, Younghun Han, Christopher I Amos

Faculty, Staff and Students Publications

Smoking may be associated with an increased risk of lung metastasis in cancers of non-lung origin. We leverage survey and electronic health record data from the diverse All of Us Research Program (AoURP) database to investigate whether smoking and smoking-related behaviors increase the risk of lung metastasis in non-lung primary cancers. The results suggest that cigarette use, measured by four continuous variables, does not increase the risk of lung metastasis in seven common cancer types but demonstrates a small significant effect in a cohort including all types of cancer in the database in both univariable and multivariable analyses. An increased …

Faculty, Staff and Student Publications

Background: Lymphopenia and failure of lymphocytes to mount an early IFN-γ response correlate with increased mortality in COVID-19. Given the essential role of CD4 helper and CD8 cytotoxic cells in eliminating viral pathogens, this profound loss in lymphocytes may impair patients' ability to eliminate the virus. IL-7 is a pleiotropic cytokine that is obligatory for lymphocyte survival and optimal function.

Methods: We conducted a prospective, double-blind, randomized, placebo-controlled trial of CYT107, recombinant human IL-7, in 109 critically ill, patients with lymphopenia who have COVID-19. The primary endpoint was to assess CYT107's effect on lymphocyte recovery with secondary clinical endpoints including …

Atypical Presentation Of Non-Small Cell Lung Carcinoma With Metastasis To Breast Tissue, Tylar P. Seckman, Diane Krutzler-Berry, Mohamed Ashal, Waqas Mahmud, Krista L. Denning, Logan M. Lawrence

Marshall Journal of Medicine

Malignant neoplasms of the lung commonly metastasize to lymph nodes, bone, brain, and liver via hematogenous and lymphatic routes. Much less commonly, metastasis occurs in the breast. Secondary metastatic disease of the breast is very rare, with a reported incidence ranging from 0.4-1.3%­­—with primary lung cancer being one of the most anomalous sources. This case details non-small cell lung cancer metastasis to the breast with proven primary contralateral lung origination. This atypical finding prompts medical professionals to consider these malignant cells' immunologic, histologic, and pathologic makeup to understand further and treat the neoplasm.

A Scoping Review Of Population Diversity In The Common Genomic Aberrations Of Clear Cell Renal Cell Carcinoma, Sean S. Kumar, Ninad Khandekar, Komal Dani, Saina R. Bhatt, Vinay Duddalwar, Anishka D' Souza

Department of Medicine Faculty Publications

Introduction: Previous literature has shown that clear cell renal cell carcinoma (ccRCC) is becoming a more prevalent diagnosis and that the incidence and mortality differ both regionally and racially. While the molecular profiles for ccRCC are studied regionally through biopsy and sequencing techniques, the genomic landscape and ccRCC diversity data are not well studied. We conducted a review of the known genomic data on 6 of the most clinically relevant DNA biomarkers in ccRCC: von Hippel-Lindau (vHL), Polybromo-1 (PBRM1), Breast Cancer Gene 1-Associated Protein 1 (BAP1), Histone-Lysine N-Methyltransferase Domain-Containing 2 (SETD2), Mammalian Target of Rapamycin (mTOR), and Lysine-Specific Demethylase 5C …

Department Dermatology Faculty Publications

Limited evidence exists regarding the long-term oncologic safety of biologic therapies, particularly interleukin (IL)-17 inhibitors (IL-17i) and IL-23i, in the management of psoriasis. This propensity-score-matched retrospective-cohort study assessed the risk of developing a primary malignancy within 10-years following exposure to an FDA-approved biologic among psoriasis patients compared to biologic-naïve controls. After propensity-score-matching, 32,230 biologic-exposed patients were further grouped into cohorts of tumor necrosis factor inhibitors (TNFi, n=16,011), IL-23i (n=5,604), IL-12/23i (n=3,856), and IL-17i (n=5,467). During a 10-year period, TNFi-treated patients had a reduced risk of developing any primary malignancy compared to biologic-naïve psoriasis patients [HR 0.80(0.73-0.87)]. Similarly, a lower incidence …

Theses and Dissertations--Epidemiology and Biostatistics

The COVID-19 Pandemic led to global societal disruptions as political leaders and public health authorities attempted to control the spread of the newly discovered SARS- CoV-2 virus. While these measures were designed to lessen morbidity and mortality from a novel pathogen, their impact was also felt in many other, often unintended ways. The purpose of this dissertation is to use cancer surveillance research methods to examine the association between COVID-19 Pandemic-related disruptions and changes in the normal diagnosis and care of cancer in the United States.

The first two studies of this dissertation analyzed reductions in cancer diagnoses in the …

Comparison Of Dynamic Mode Decomposition With Other Data-Driven Models For Lung Cancer Incidence Rate Prediction, L. Raymond Guo, Jifu Tan, M. Courtney Hughes

Faculty Articles, Papers, and Other Scholarship

Introduction: Public health data analysis is critical to understanding disease trends. Existing analysis methods struggle with the complexity of public health data, which includes both location and time factors. Machine learning offers powerful tools but can be computationally expensive and require specialized knowledge. Dynamic mode decomposition (DMD) is an alternative that offers efficient analysis with fewer resources. This study explores applying DMD in public health using lung cancer data and compares it with other machine learning models.

Methods: We analyzed lung cancer incidence data (2000–2021) from 1,013 US counties. Machine learning models (random forest, gradient boosting machine, support vector machine) …

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, …
