Genetic And Serological Markers In Colorectal Cancer Surgery, Adrian Silaghi, Vlad Denis Constantin, Dragos Serban, Dragos Epistatu, Ioana Paunica, Daniela Gabriela Bălan, Laura Florentina Rebegea

Journal of Mind and Medical Sciences

Colon cancer is relatively asymptomatic in the early stages, the manifestations appearing and intensifying with the evolution of the disease, especially when associated with local and/or systemic complications. In such cases, surgical interventions are often emergency and involve more extensive operations (on metabolically and immune-stressed organisms), so that an early diagnosis (endoscopy, tumor markers, etc.) remains not only desirable but even a priority, especially in predisposed patients (genetic factors, lifestyle, etc.). As a consequence, the involvement of tumor markers in colon neoplasms has become more and more investigated in recent times. This review investigates the roles of serological and genetic …

Targeting Tgf-Β During Epithelial-To-Mesenchymal Progression As An Effective Therapy Against Colorectal Cancer, Joyce Fan

Undergraduate Research

Colorectal cancer is one of the most common cancers worldwide. Understanding the mechanisms of colorectal cancer progression is crucial for the development of effective therapeutics. Epithelial-to-mesenchymal transition is a hallmark feature of cancer and is defined as the loss of epithelial cell features, such as apical-basal polarity and high expression of cell adhesion molecules, and the development of mesenchymal features, such as lack of polarity and increased cell mobility. Epithelial-to-mesenchymal is essential for cell migration, proliferation, and tumor growth. Both the TGF-β and SMAD pathway are associated with colorectal cancer progression. TGF-β is crucial to the cellular mechanism of cell …

Implementation Of An Evidence-Based Toolkit To Improve Colorectal Cancer Screening In A Federally Qualified Health Center, Stephanie Mckithan

Doctoral Dissertations and Projects

The change in payor fee-for-service to value-based care is creating an opportunity for primary care clinics nationally to adjust their focus to meeting key clinical quality measures during patient encounters. Colorectal screening is one of such quality measures. Previous research has shown that early detection saves lives. The guidelines have lowered the recommended age of initial screening to 45 due to the incidence of colorectal cancer in younger patients. But with all the objectives that need to be met in the limited time of the visit, how can nurse practitioners improve their efficiency? This evidence-based project assessed the implementation of …

Assessment Of Mucin 13 (Muc13) As An Imaging Target For Guiding Colorectal Cancer Treatment: A Pathway Towards Theranostic Development, Ryan P. Coll, Aiko Yamaguchi, Jianbo Wang, Xiaoxia Wen, Denise Hernandez, Subhash C. Chauhan, H. Charles Manning

Research Symposium

Background: A theranostic strategy combining diagnostic imaging and targeted therapy in a single regimen is proposed for improved management and treatment of colorectal cancer (CRC). Increased specificity in detection by the noninvasive imaging technique positron emission tomography (PET) can be achieved by radiolabeling antibodies (Abs) designed to target tumor-associated antigens with increased expression post-translational modifications present in cancer cells. In this study, an Ab designed to target the transmembrane glycoprotein mucin 13 (MUC13) was radiolabeled with the positron-emitting radionuclide zirconium-89 (⁸⁹Zr) for PET imaging of a xenograft mouse model of CRC.

Introduction:

Cancer is one of the most prevalent diseases from children to elderly adults. This will be deadly if not detected at an earlier stage of the cancerous cell formation, thereby increasing the mortality rate. One such cancer is colorectal cancer, caused due to abnormal growth in the rectum or colon. Early screening of colorectal cancer helps to identify these abnormal growth and can exterminate them before they turn into cancerous cells.

Aim:

Therefore, this study aims to develop a robust and efficient classification system for colorectal cancer through Convolutional Neural Networks (CNNs) on histological images.

Comparing The Ppv Of At-Home Screening Tests With Chronic Anticoagulant And/Or Antiplatelet Therapies, Bradley Gustafson, Nasima Mehraban, Amjad Awan, Michele Mccarroll

North Texas Research Forum 2024

BACKGROUND: With the rising incidence and mortality of colorectal cancer (CRC), early diagnosis and treatment is imperative. At-home CRC screening kits are a non-invasive Federal Drug Association (FDA) approved designed to detects either hemoglobin or DNA markers associated for CRC and high-grade polyps. Therefore, therapies that have a propensity to increase rates of gastrointestinal bleeding could theoretically lead to higher false positive rates. The goal of this study was to determine the positive predictive value of at-home screening tests when applied to patients on therapies such as antiplatelet, anticoagulant, non-steroidal anti-inflammatory (NSAID), or a combination of the three. METHODS: The …

Advances in Clinical Medical Research and Healthcare Delivery

Colorectal cancer (CRC) is the second most common cause of cancer death in the United States. Relative to a 5-year survival rate, CRC patients diagnosed with localized disease accrue a 90% survival rate while those diagnosed with distant-stage disease maintain 14% survival. Mucinous adenocarcinoma (MAC) is a unique subtype of CRC characterized by the presence of extracellular mucin occupying 50% of tumor expansion. Fistula complications of colonic malignancy have rarely been reported and more commonly occur as complications of diverticulitis. Colocolic fistulae are atypical consequences of colon cancer, which have been rarely reported. We wish to report a unique case …

Implementation Of Standardized Patient Education To Improve Adherence With Colonoscopy For Colorectal Cancer Screening, Melissa Leal Hearn, Melissa M. Hessock, Tara L. Hahn

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

BACKGROUND: Colorectal cancer (CRC) is the third leading cause of cancer deaths among men and women in the U.S. CRC is preventable and manageable when detected early. Approximately 30% of average-risk Americans are overdue for colonoscopy screening. Colonoscopy screenings can reduce death by 67%. Current evidence suggests CRC screening education improves screening uptake among men and women at average-risk age.

LOCAL PROBLEM: The setting of this practice improvement project was a private colorectal surgery practice in South Texas, serving primarily Hispanic/Latino and Caucasian patients. Cancellation rates before colonoscopy were 16.8%, and there was no standardized education for CRC …

Mucin Muc13 And Yap1 Correlate With Poor Survival In Colorectal Cancer, Sudhir Kotnala, Anupam Dhasmana, Kyle Doxtater, Meena Jaggi, Murali M. Yallapu, Manish Tripathi, Subhash C. Chauhan

Research Symposium

Background: Metastatic disease contributes to over 90% of cancer-associated deaths. Colorectal cancer (CRC), the second lethal malignancy, has the greatest incidence and mortality rates in the Southern United States. Over 40-50% of CRC patients acquire metastasis at some point throughout their disease's progression. CRC survival rate drops from 90%-14% when the disease is confined within the colon and therefore “early diagnosis” becomes imperative to determine timely and quality treatments. We have identified that MUC13 protein translocate to nucleus along with transcription factor Yes-Associated Protein 1 (YAP1) during anchorage independent conditions (metastatic phenotype). YAP1 is known to be overexpressed in CRC …

Urolithin A As A Potential Agent For Prevention Of Age-Related Disease: A Scoping Review., Breanne Kothe, Sarah Klein, Stephanie N. Petrosky

HPD Articles

The aging of an organism is hallmarked by systemic loss of functional tissue, resulting in increased fragility and eventual development of age-related neurodegenerative, musculoskeletal, cardiovascular, and neoplastic diseases. Growing scientific evidence points to mitochondrial dysfunction as a key contributor in the aging process and subsequent development of age-related pathologies. Under normal physiologic conditions, the body removes dysfunctional mitochondria via an autophagic process known as mitophagy. Urolithin A (UA), a metabolite produced when gut microflora digests the polyphenol compounds ellagitannin and ellagic acid, is a known inducer of mitophagy via several identified mechanisms of action. The primary objective of this scoping …

Dynamic Role Of Exosome Micrornas In Cancer Cell Signaling And Their Emerging Role As Noninvasive Biomarkers, Jaya Aseervatham

Department of Neurology Faculty Papers

Exosomes are extracellular vesicles that originate from endosomes and are released by all cells irrespective of their origin or type. They play an important role in cell communication and can act in an autocrine, endocrine, or paracrine fashion. They are 40–150 nm in diameter and have a similar composition to the cell of origin. An exosome released by a particular cell is unique since it carries information about the state of the cell in pathological conditions such as cancer. miRNAs carried by cancer-derived exosomes play a multifaceted role by taking part in cell proliferation, invasion, metastasis, epithelial–mesenchymal transition, angiogenesis, apoptosis, …

Colon Cancer Screening And The Association With Colon Cancer Incidence And Mortality Rates In Ethnic Minority Groups, Jovonne Smith

Student Scholar Showcase

Colorectal cancer (CRC) continues to be a public health burden and is the second leading cause of American cancer deaths. Strides have been made in the medical community, and there has been an overall decrease in CRC rates. This decrease is primarily due to a cumulative decline in late-onset colorectal cancer diagnosis (LOCRC), defined as CRC cancer in adults over the age of 50 years. CRC continues to burden American Indians and Alaska Natives (AIAN) and Non-Hispanic Black individuals (NHB) disproportionately. The incidence and mortality rates remain disproportionately higher than other ethnic groups, and the survival rate is lower than …

Exploring The Use Of Bidirectional Text Messaging Reminders To Increase Colorectal Cancer Screening Rates In Patients Prescribed Cologuard®, James Harris

Translational Projects (Open Access)

Meaningfully engaging with patients through technology is becoming increasingly important in healthcare. Mailed letters, phone calls, and even one-way text messaging or some combination of these have all been utilized to communicate with patients regarding preventative healthcare screening measures, with varying degrees of success. While many studies have examined the use of bidirectional text messaging (BTM) to engage patients regarding mammograms, cervical cancer screening, and other issues, very little literature exists on BTM concerning colorectal cancer (CRC).

Therefore, this project sought to examine the impact of BTM between two primary care clinics and their respective patients who were prescribed and …
