Association Between Smoking And Molecular Subtypes Of Colorectal Cancer, Xiaoliang Wang, Yin Cao, Et Al

Open Access Publications

Background: Smoking is associated with colorectal cancer (CRC) risk. Previous studies suggested this association may be restricted to certain molecular subtypes of CRC, but large-scale comprehensive analysis is lacking.

Methods: A total of 9789 CRC cases and 11 231 controls of European ancestry from 11 observational studies were included. We harmonized smoking variables across studies and derived sex study-specific quartiles of pack-years of smoking for analysis. Four somatic colorectal tumor markers were assessed individually and in combination, including

Results: Heavier smoking was associated with higher risk of CRC overall and stratified by individual markers (

Conclusion: Smoking was associated with …

Ngn3-Positive Cells Arise From Pancreatic Duct Cells, Chiemi Kimura-Nakajima, Kousuke Sakaguchi, Yoshiko Hatano, Masahito Matsumoto, Yasushi Okazaki, Keisuke Tanaka, Takumi Yamane, Yuichi Oishi, Kenji Kamimoto, Ken Iwatsuki

Open Access Publications

The production of pancreatic β cells is the most challenging step for curing diabetes using next-generation treatments. Adult pancreatic endocrine cells are thought to be maintained by the self-duplication of differentiated cells, and pancreatic endocrine neogenesis can only be observed when the tissue is severely damaged. Experimentally, this can be performed using a method named partial duct ligation (PDL). As the success rate of PDL surgery is low because of difficulties in identifying the pancreatic duct, we previously proposed a method for fluorescently labeling the duct in live animals. Using this method, we performed PDL on neurogenin3 (Ngn3)-GFP transgenic mice …

Emerging Genotype-Phenotype Relationships In Primary Ciliary Dyskinesia, Steven K Brennan, Thomas W Ferkol, Stephanie D Davis

Open Access Publications

Primary ciliary dyskinesia (PCD) is a rare inherited condition affecting motile cilia and leading to organ laterality defects, recurrent sino-pulmonary infections, bronchiectasis, and severe lung disease. Research over the past twenty years has revealed variability in clinical presentations, ranging from mild to more severe phenotypes. Genotype and phenotype relationships have emerged. The increasing availability of genetic panels for PCD continue to redefine these genotype-phenotype relationships and reveal milder forms of disease that had previously gone unrecognized.

Evaluation Of The Neonatal Sequential Organ Failure Assessment And Mortality Risk In Preterm Infants With Late-Onset Infection, Noa Fleiss, Angela N. Lewis, Krista E. Cooksey, Ameena N. Husain, Misty Good, Et Al

Open Access Publications

Importance: Infection in neonates remains a substantial problem. Advances for this population are hindered by the absence of a consensus definition for sepsis. In adults, the Sequential Organ Failure Assessment (SOFA) operationalizes mortality risk with infection and defines sepsis. The generalizability of the neonatal SOFA (nSOFA) for neonatal late-onset infection-related mortality remains unknown.

Objective: To determine the generalizability of the nSOFA for neonatal late-onset infection-related mortality across multiple sites.

Design, Setting, and Participants: A multicenter retrospective cohort study was conducted at 7 academic neonatal intensive care units between January 1, 2010, and December 31, 2019. Participants included 653 preterm ( …

Effects Of Dietary Restriction On Neuroinflammation In Neurodegenerative Diseases, Luigi Fontana, Laura Ghezzi, Anne H. Cross, Laura Piccio

Open Access Publications

Recent and accumulating work in experimental animal models and humans shows that diet has a much more pervasive and prominent role than previously thought in modulating neuroinflammatory and neurodegenerative mechanisms leading to some of the most common chronic central nervous system (CNS) diseases. Chronic or intermittent food restriction has profound effects in shaping brain and peripheral metabolism, immunity, and gut microbiome biology. Interactions among calorie intake, meal frequency, diet quality, and the gut microbiome modulate specific metabolic and molecular pathways that regulate cellular, tissue, and organ homeostasis as well as inflammation during normal brain aging and CNS neurodegenerative diseases, including …

Microbiota Signals Suppress B Lymphopoiesis With Aging In Mice, Joseph R Krambs, Darlene A Monlish, Feng Gao, Laura G Schuettpelz, Daniel C Link

Open Access Publications

Aging is associated with significant changes in hematopoiesis that include a shift from lymphopoiesis to myelopoiesis and an expansion of phenotypic hematopoietic stem cells (HSCs) with impaired self-renewal capacity and myeloid-skewed lineage differentiation. Signals from commensal flora support basal myelopoiesis in young mice; however, their contribution to hematopoietic aging is largely unknown. Here, we characterize hematopoiesis in young and middle-aged mice housed under specific pathogen free (SPF) and germ-free (GF) conditions. The marked shift from lymphopoiesis to myelopoiesis that develops during aging of SPF mice is mostly abrogated in GF mice. Compared with aged SPF mice, there is a marked …

Antibiotic-Driven Intestinal Dysbiosis In Pediatric Short Bowel Syndrome Is Associated With Persistently Altered Microbiome Functions And Gut-Derived Bloodstream Infections, Robert Thänert, Anna Thänert, Jocelyn Ou, Adam Bajinting, Carey-Ann D Burnham, Holly J Engelstad, Maria E Tecos, I Malick Ndao, Carla Hall-Moore, Colleen Rouggly-Nickless, Mike A Carl, Deborah C Rubin, Nicholas O Davidson, Phillip I Tarr, Barbara B Warner, Gautam Dantas, Brad W Warner

Open Access Publications

Surgical removal of the intestine, lifesaving in catastrophic gastrointestinal disorders of infancy, can result in a form of intestinal failure known as short bowel syndrome (SBS). Bloodstream infections (BSIs) are a major challenge in pediatric SBS management. BSIs require frequent antibiotic therapy, with ill-defined consequences for the gut microbiome and childhood health. Here, we combine serial stool collection, shotgun metagenomic sequencing, multivariate statistics and genome-resolved strain-tracking in a cohort of 19 patients with surgically-induced SBS to show that antibiotic-driven intestinal dysbiosis in SBS enriches for persistent intestinal colonization with BSI causative pathogens in SBS. Comparing the gut microbiome composition of …

A Mixed Methods Study Examining The Barriers And Facilitators To Research Utilization And Evidence-Based Practice In Adult Weight Management, Kevin B. Metcalf

UNF Graduate Theses and Dissertations

Background

Obesity is a disease with many associated comorbidities and its prevalence in the U.S. continues to increase despite the majority of people with obesity attempting weight loss. Dietitians are responsible for using evidence-based practice to mitigate the effects of obesity, however, differences in practice philosophies, opinion leaders, misinformation, a sense of competence, and the complexity of nutrition research have been identified as barriers to implementing practice guidelines into daily practice. It is unclear how dietitians strike a balance between empirical evidence, anecdotal evidence, and patient-centered practice.

Aims

The primary aim of this mixed-methods study was to identify the barriers …

Physician Knowledge, Attitudes, And Behaviors Towards Registered Dietitian Nutritionists, Amy Motley Jones

UNF Graduate Theses and Dissertations

Diet is increasingly linked with overall quality of life, and a healthy diet is now being considered one of the cornerstones of preventative care. Physicians rely on Registered Dietitian Nutritionists (RDNs) as most doctors lack the nutrition knowledge to properly treat their patients, especially during their residency. Little published information exists on the specific collaboration of RDNs and resident physicians. This study aimed to determine whether mentoring with an RDN increased physician nutrition knowledge, increased consults to RDNs, and whether physician attitudes improved regarding their understanding of the role of the RDN in healthcare. Knowledge or attitude alone are not …

Performance Of A Native Butterfly And Introduced Moth On Native And Introduced Lineages Of Phragmites Australis, Adam M. Lambert, Lisa A. Tewksbury, Richard A. Casagrande

Plant Sciences and Entomology Faculty Publications

This study examined the performance of Poanes viator (Edwards) (Hesperiidae), a native North American skipper, and Rhizedra lutosa (Hübner) (Noctuidae), an introduced moth, reared on native and non-native, invasive lineages of Phragmites australis. Poanes viator is a generalist on monocots and larvae were also fed leaves of Zizania aquatica, a native macrophyte that the skipper commonly uses as a host plant. Larval survival and duration, pupal weight, and pupation time were compared for P. viator feeding on leaf tissue and R. lutosa feeding on rhizomes of either native or introduced plants. We also tested an artificial diet supplemented with P. …

Quantifying Avoidable Food Waste And Identifying Its Underlying Causes: A Case Study Of A University Dormitory In Thailand, Shimpei Iwasaki, Suphat Prasopsin, Thamarat Phutthai

Applied Environmental Research

To develop well-planned and effective policies and programs for reducing avoidable food waste, it is important to quantify the actual food waste level in particular settings and assess relationships among consumers’ awareness, attitudes, and behaviors. Recognizing these considerations, this paper measured avoidable food waste generated by university students living in dormitory buildings and identified its underlying causes in the case of Kanchanaburi campus, Mahidol University, Thailand. The study applied a food waste composition survey 18 times between January and May 2019 while administering questionnaires in October 2019 to the dormitory students. Based on these measures, the study identified 1,417 instances …

Added Sugar Consumption And Prediabetes In U.S. Adults: A Cross-Sectional Analysis Of The National Health And Nutrition Examination Survey, 2013-2018, Nadia Markie Sneed

All ETDs from UAB

Prediabetes is a modifiable risk factor for type 2 diabetes (T2D) that effects 88- million U.S. adults. Added sugar is linked to the risk for prediabetes through direct and indirect mechanisms that promote hepatic and whole-body insulin resistance. Added sugar is overconsumed and totals ~13% of American’s daily caloric intake, with consumption highest for non-Hispanic Blacks and Hispanic minority populations also disproportionality affected by prediabetes and T2D. The effects of total added sugar on prediabetes have been mixed; however, total added sugar intake has primarily been examined using added sugar proxies (e.g., sugar-sweetened beverages, fructose), likely increasing systemic measurement error …

Developing A Core Set Of Nursing-Sensitive Indicators For International Pediatric Oncology Nursing Practice, Courtney Erin Sullivan

All ETDs from UAB

Although nursing sensitive indicators (NSIs) have been developed to measure factors influencing nursing care quality and patient outcomes in general and in select specialty areas, a core set of NSIs for international pediatric oncology nursing practice does not exist. Quality nursing care delivery in pediatric oncology is essential to achieving optimal patient outcomes and closing the 50% survival gap between high-income and low- and middle-income countries. To enhance global childhood cancer outcomes influenced by nursing, this dissertation research was conducted with the purpose of developing a preliminary core set of NSIs for international pediatric oncology nursing that is important, actionable, …

Inflammation, Executive Function, And Adiposity In Children With Or At Risk For Obesity, Kathryn L. Prendergast

All ETDs from UAB

Obesity is associated with executive function (EF) deficits across the lifespan. Higher body mass index (BMI), greater severity of obesity, and poorer adherence and weight outcomes in obesity treatment have all been associated with EF deficits. Adult literature has begun to emphasize neuroinflammation in obesity as a possible pathway to later cognitive impairment. However, the pediatric obesity literature has yet to even establish associations between peripheral inflammation and EF. Thus, the present study aimed to examine associations and variability in inflammatory biomarkers, EF, and adiposity in children with or at risk for obesity. Additionally, inflammation was examined as a mechanism …

Biomarker And Target Discovery In Cancer, Alyncia Dominique Robinson

All ETDs from UAB

Cancer is a complex disease characterized by uncontrolled growth of transformed cells that can arise in many tissue types throughout the body (e.g., breast, lung, prostate, pancreas, lymph nodes) and is a major cause of death worldwide. Cancer progression resulting in aggressive or metastatic disease accounts for one of the leading causes of death worldwide, second only to heart disease in the US. Incidentally, cancer-related mortality has been on a steady decline, dropping 25% over the last 25 years [1]. This could be attributed to improved and earlier diagnoses and better treatment options being developed over the past few decades. …

Keller-Segel Type Chemotaxis Model: Asymptotic Behavior Of The Small Data Solution, Jean D. Rugamba

All ETDs from UAB

This dissertation’s work is on asymptotic behavior of a Keller- Segel type chemotaxismodel with logarithmic sensitivity and logistic growth. The logarithmic singularity in the system is removed via the inverse Hopf-Cole transformation. Then, for the transformed system, we study the Green’s function of the corresponding linear system, linearized around a constant equilibrium solution, and the results give us a detailed point-wise description of the Greens function, which, itself, is significant in linear theory. Next, with the results on the Green’s function, we study small data solution to the nonlinear system by making use of Duhamel’s principle. This provides a descriptive …

Urban School Leaders’ Perceptions Of Community Education Within Essentialist Educational Policy Contexts, Ashley Samuels

All ETDs from UAB

Urban schools face the enormous task of providing a wide range of support to students. These supports include academics, socio-emotional learning, health, nourishment, and even clothing. Students arrive with challenges that make it difficult to concentrate on their academic studies. The community education model can supply students in urban schools with needed resources so that they may prioritize their academics. A community education model is a holistic approach to providing support to students. With this in mind, the urban school leader must find a way to provide comprehensive support to students, both through community education and in consideration of essentialist …
