Effects Of Chewing Time On Gastrointestinal Discomfort, Substrate Use, And Performance During Running, Thomas Geaney

Human Movement Sciences Theses & Dissertations

Previous research has shown that food particle size affects gastric processing. For example, food particles greater than 3 mm may delay gastric emptying under certain conditions. Delays in gastric emptying can be problematic during aerobic exercise, leading to nausea, bloating, fullness, and other gastrointestinal (GI) symptoms. In some cases, symptoms can be severe enough to negatively affect athletic performance. This study investigated the effects of manipulating chewing duration of carbohydrate sports bars on GI discomfort, physiological responses, and performance during endurance running. This crossover study recruited 12 male runners (age: 36.4 ± 7.2 years, VO_2peak: 57.2 ± 4.7 …

Short-Term Improvement In Self-Perceived Knowledge And Weight Bias Following A 15-Week Course On Pediatric Obesity, Rosanna P. Watowicz, Harrine Ramesh

Journal of Dietetic Education

Registered dietitian nutritionists (RDNs)are an integral part of weight management teams; however, previous research indicates that RDNs may hold weight-related biases. Additionally, there may be a gap between what RDNs learn about weight management during their education and training and the competencies that RDNs should achieve before working in weight management. The objective of this study was to examine whether a 15-week graduate course on pediatric obesity led to a short-term increase in self-perceived knowledge of 13 Obesity Medicine Education Collaborative competencies, as well as a short-term decrease in weight bias. Nutrition graduate students enrolled in the course completed a …

Effectiveness Of Simulation-Based Learning On Clinical Competence In Dietetics Students: A Narrative Review, Claudia W. Scott, Rena Zelig, Diane L. Rigassio Radler

Journal of Dietetic Education

Clinical supervised practice experiences offered through dietetic internships have historically been among the most challenging to obtain. The COVID-19 pandemic heightened the scarcity of these experiences and forced dietetics education programs to offer alternative experiences in the absence of direct patient care opportunities. Simulation-based learning experiences (SBLE) or objective structured clinical examinations (OSCE) are one method of providing these alternative options, and if effective, could be routinely incorporated into dietetics education. This review evaluates five original research articles to determine the effectiveness of simulation-based learning on perceived or observed clinical competence in dietetic students. The findings of the studies unanimously …

Undergraduate And Graduate Students’ Retrospective Perception Of Flipped Learning In Dietetics Curricula, Rachel L. Vollmer, Teresa Drake

Journal of Dietetic Education

Most studies investigating flipped learning fail to assess how student perceptions of flipped learning may change once the class is complete, and students have a chance to reflect on the experience. Follow-up studies are needed to evaluate the sustainability of the benefits from flipped learning among students and how they feel it prepares them, if at all, for future classes and/or their professional lives. Therefore, the objective of this study was to explore how graduate and undergraduate dietetics students retrospectively perceive a course that used flipped learning 2 years after they completed the course. Two focus groups with undergraduate (n=5) …

Homeobox Transcription Factor Hbxa Influences Expression Of Over One Thousand Genes In The Model Fungus Aspergillus Nidulans, Sandesh S. Pandit, Jinfang Zheng, Yanbin Yin, Sophie Lorber, Olivier Puel, Sourabh Dhingra, Eduardo A. Espeso, Ana M. Calvo

Nutrition and Health Sciences -- Faculty Publications

In fungi, conserved homeobox-domain proteins are transcriptional regulators governing development. In Aspergillus species, several homeobox-domain transcription factor genes have been identified, among them, hbxA/hbx1. For instance, in the opportunistic human pathogen Aspergillus fumigatus, hbxA is involved in conidial production and germination, as well as virulence and secondary metabolism, including production of fumigaclavines, fumiquinazolines, and chaetominine. In the agriculturally important fungus Aspergillus flavus, disruption of hbx1 results in fluffy aconidial colonies unable to produce sclerotia. hbx1 also regulates production of aflatoxins, cyclopiazonic acid and aflatrem. Furthermore, transcriptome studies revealed that hbx1 has a broad effect on the A. flavus …

Studies Of The Role Of Mtorc1 In Modulating Intestinal Epithelial Barrier Function, Isaac Adediji

Department of Nutrition and Health Sciences: Dissertations, Theses, and Student Research

Mechanistic target of rapamycin complex 1 (mTORC1) signaling impacts intestinal inflammation by modulating the production of cytokines in both intestinal epithelial cells and macrophages. Recent evidence revealed that THP-1-derived macrophages with elevated mTORC1 activity (THP-1shTSC2 macrophages), exhibited increased proinflammatory cytokine production when stimulated with lipopolysaccharide (LPS) compared to counterpart macrophages with repressed or baseline mTORC1 activity. Furthermore, it has been shown that mTORC1 governs intestinal barrier function as evidenced by elevated transepithelial electrical resistance (TEER) and para/transcellular permeability in Raptor-depleted Caco-2 cells (cells with repressed mTORC1 activity) compared to Caco-2 cells with elevated or baseline mTORC1 activity. The present study …

Diet-Microbiome-Immune Interplay In Multiple Sclerosis: Understanding The Impact Of Phytoestrogen Metabolizing Gut Bacteria, Peter C. Lehman, Sudeep Ghimire, Jeffrey D. Price, Amanda E. Ramer-Tait, Ashutosh K. Mangalam

Nutrition and Health Sciences -- Faculty Publications

Multiple sclerosis (MS) is a chronic and progressive autoimmune disease of the central nervous system (CNS), with both genetic and environmental factors contributing to the pathobiology of the disease. Although HLA genes have emerged as the strongest genetic factor linked to MS, consensus on the environmental risk factors is lacking. Recently, the gut microbiota has garnered increasing attention as a potential environmental factor in MS, as mounting evidence suggests that individuals with MS exhibit microbial dysbiosis (changes in the gut microbiome). Thus, there has been a strong emphasis on understanding the role of the gut microbiome in the pathobiology of …
