Health Consequences Of Low Energy Availability In Females And Their Underlying Physiological Mechanisms, Grace Parry

Senior Honors Theses

Low energy availability (LEA) is a state in which energy intake is insufficient to support energy expenditure while maintaining energy balance, which has been shown to result in gastrointestinal distress, immunosuppression, reduced metabolic rate, menstrual dysfunction, diminished bone health, and impaired cardiovascular function in females. Alterations to the microbiome and mucosal lining may propagate gastrointestinal complaints and compromised immune function associated with LEA. The pathophysiology of LEA is otherwise largely driven by hormonal adaptations. Diminished production of thyroid hormones is known to contribute to reduced metabolic rate. Decreases in leptin and insulin and increases in ghrelin disrupt reproductive function through …

Scurvy, Abnormal Mri, And Gelatinous Bone Marrow In An Adolescent With Avoidant Restrictive Food Intake Disorder, Ginny Claire Kim, Asha M Davidson, Rebecca M Beyda, Mona A Eissa

BACKGROUND: Although medical literature describes pediatric scurvy as "rare", a growing number of case reports suggests otherwise. Patients often undergo costly and unnecessary workup due to unfamiliarity with the presentation of scurvy. This case report further supports the small yet growing literature documenting scurvy and its manifestations in patients with eating disorders.

CASE PRESENTATION: A 15-year-old female presented to the emergency department with bilateral knee and ankle swelling and pain in the setting of chronic lower limb rash and BMI of 16.3. For years, she had restricted her diet to carbohydrates. Exam showed perifollicular petechial hemorrhagic rash with corkscrew hairs, …

Ideal Body Weight And Body Fat Percentage Predict Relative Energy Deficiency In Sport (Red-S) Scores In Collegiate Athletes, Emily Norman

Theses and Dissertations--Nutrition and Food Systems

Background: Low energy availability (LEA) is the underlying cause of Relative Energy Deficiency in Sport (RED-S) which negatively affects athletes' physiological function, health, and performance. RED-S results from inadequate dietary intake to support energy expenditure for daily living, growth, and optimal performance. It occurs in both male and female athletes, with or without disordered eating. However, screening and diagnosis in athletes can be difficult. Objective: This study aims to identify strong predictors of RED-S and assess its prevalence in collegiate male and female athletes. Methods: A total of 270 NCAA athlete test points from mixed sports were evaluated for RED-S …

High Cholesterol Diet Induces Sudden Death In Mice With Impaired Reverse Cholesterol Transport, Misa Ito

Theses and Dissertations--Pharmacology and Nutritional Sciences

Unexplained sudden death continues to be a major public health crisis as AHA reports that 1,000 people suffer sudden cardiac arrest each day in the U.S. with only 10% surviving. A number of ongoing challenges hinder to understand the sudden death. Thus, investigating underlined mechanisms of sudden death is urgent. Unexpectedly, I found a high cholesterol diet (HCD)-induced sudden death preclinical model. Although HCD is associated with a higher risk of cardiovascular disease (CVD) and the subendothelial lipoprotein retention theory is well established for atherosclerosis development, these theories cannot explain the sudden death in my model because atherosclerosis and CVD …

Lifestyle Tools For Men’S Health And Disease Prevention: Well-Being Through Nutrition, Physical Activity, Stress Management, And Connection, Leigh A. Frame

Clinical Research and Leadership Faculty Publications

Mental health is an often-overlooked aspect of overall health and wellness (well-being). Mental illness is increasingly common with 1 in 5 American adults experiencing it annually, and 1 in 20 suffering from a serious mental illness each year [1]. Treatment rates for mental illness are lower in men (37.4%) compared to women (51.2%) [1]. Globally, treatment rates are similar with an estimated cost to the global economy of $1 trillion annually, yet less than 2% of government health expenditure is for mental health worldwide [2]. Despite this, only nine studies have been published specifically targeting men’s mental health through lifestyle …

Acafinder: Genome Mining For Anti-Crispr-Associated Genes, Bowen Yang, Jinfang Zheng, Yanbin Yin

Food for Health: Publications

Anti-CRISPR (Acr) proteins are encoded by (pro)viruses to inhibit their host’s CRISPR-Cas systems. Genes encoding Acr and Aca (Acr associated) proteins often colocalize to form acr-aca operons. Here, we present AcaFinder as the first Aca genome mining tool. AcaFinder can (i) predict Acas and their associated acr-aca operons using guilt-by-association (GBA); (ii) identify homologs of known Acas using an HMM (Hidden Markov model) database; (iii) take input genomes for potential prophages, CRISPR-Cas systems, and self-targeting spacers (STSs); and (iv) provide a standalone program (https://github.com/boweny920/AcaFinder) and a web server (http://aca .unl.edu/Aca). AcaFinder was applied to mining over …

Clinical And Biological Factors With Prognostic Value In Acute Pancreatitis, Mihai Faur, Dan Dumitrescu, Dan Sabau, Ciprian Tanasescu, Dan Cretu, Denisa Tanasescu, Vlad Denis Constantin, Calin Mohor

Journal of Mind and Medical Sciences

Acute pancreatitis is an acute inflammatory process of the pancreas, which can remain localized at the level of the gland or can extend to the peripancreatic and retroperitoneal tissues. The use and interpretation of paraclinical examinations at the onset can predict the form of evolution of acute pancreatitis (mild or severe). Depending on the evolution, these data are useful in determining the type of surgical intervention that might be necessary based on severity.

We present a retrospective study consisting of 118 patients diagnosed and hospitalized with acute pancreatitis during 2016-2020 in the Surgery I section of the Sibiu County Emergency …

Food for Health: Publications

The effects of fiber, complex carbohydrates, lipids, and small molecules from food matrices on the human gut microbiome have been increasingly studied. Much less is known about how dietary protein can influence the composition and function of the gut microbial community. Here, we used near-isogenic maize lines of conventional popcorn and quality-protein popcorn (QPP) to study the effects of the opaque-2 mutation and associated quality-protein modifiers on the human gut microbiome. Opaque-2 blocks the synthesis of major maize seed proteins (α-zeins), resulting in a compensatory synthesis of new seed proteins that are nutritionally beneficial with substantially higher levels …

The Impact Of Dietary Fiber On Breast Cancer Incidence, Peyton North

Epsilon Sigma at-Large Research Conference

Abstract

Introduction & Background

The role of dietary fiber in breast cancer etiology remains unclear. A negative correlation may be due to fiber’s ability to stave off obesity and aid in the extraction of serum estrogen, two known risk factors for the disease. Effects may differ by source, and type, of fiber. Most of the data available is from research with non-Hispanic white women. However, fiber intake may vary significantly across cultures.

Purpose Statement & Question

The research sought to investigate whether an increased intake of dietary fiber was associated with a corresponding decrease in the incidence of breast cancer. …

Apoe Genotype And Sex Modulate Ketogenic Diet Enhancements To Metabolism And Gut Microbiome In Young Mice, Andrew T. Yackzan

Theses and Dissertations--Medical Sciences

The apolipoprotein ε (APOE) allele in humans has been associated with risk for development of Alzheimer’s disease (AD). There are predominately three variations of the allele – ε2 (E2), ε3 (E3), and ε4 (E4) – with E4 contributing the greatest risk of AD development. Recent research has unveiled evidence of neurometabolic and neurovascular deficits in E4 carriers present decades before the onset of dementia; it is believed these chronic defects play a major role in the development of AD, thus making them a potential target for preventative intervention. The purpose of this study was to examine the effect of a …

The Physiological Benefits Of A Plant-Based Diet On Cardiovascular Health, Jenevieve Petray

Nursing | Senior Theses

Cardiovascular disease (CVD) is increasingly more prevalent in today’s society and is attributed to an alarming percentage of American hospitalizations and deaths. Americans are unhealthier than ever before, and the main contributor is the Western diet. Diet is a double-edged sword that can offer benefits or detriments to one’s health. CVD encompasses numerous diagnoses originating from various underlying physiological alterations. These alterations are downstream effects of increased body weight and BMI, increased cholesterol levels, decreased insulin sensitivity and increased arterial plaque buildup. Research shows that a plant-based diet has the potential to manage and reverse all fundamental physiological alterations that …

Background and aims: Diet may contribute to the increasing incidence of colorectal cancer (CRC) before age 50 (early-onset CRC). Microbial metabolism of dietary sulfur produces hydrogen sulfide (H₂S), a gastrointestinal carcinogen that cannot be easily measured at scale. As a result, evidence supporting its role in early neoplasia is lacking.

Methods: We evaluated long-term adherence to the sulfur microbial diet, a dietary index defined a priori based on increased abundance of 43 bacterial species involved with sulfur metabolism, with risk of CRC precursors among 59,013 individuals who underwent lower endoscopy in the Nurses’ Health Study II …

The gastrointestinal microbiome contains at least 100 trillion microorganisms (bacteria, viruses, fungi), whose distribution varies from the mouth to the rectum spatially and temporally throughout one's lifetime. The microbiome benefits from advancing research due to its major role in human health. Studies indicate that its functions are immunity, metabolic processes and mucosal barrier. The disturbances of these functions, dysbiosis, influence physiology, lead to diabetes, inflammatory bowel disease, obesity and colon tumorigenesis. The third most common form of cancer, colorectal cancer, is the result of many factors and genes, and although the link between dysbiosis and this type of cancer is …

The economic burden this costs a nation can be astronomic both in terms of expense and loss in productivity. One-third of U.S. adults, 86 million people, have prediabetes. Effective management is needed that can reach these 86 million, and others at high risk, to reduce their progression to diagnosed Type 2 diabetes. After the literature review, there was not enough literature to support how these led to the progression to diabetes. The abundant literature is centered …

The Effect Of Polyunsaturated And Saturated Fatty Acids On Seizure Presence And Severity In A Cohort Of Subjects In An Epilepsy Monitoring Unit, Jana K. Wells

Theses & Dissertations

Ketogenic diet therapies (KDTs) have been used to treat epilepsy for nearly 100 years. Although effective, restrictive diet patterns and unknown impacts on long-term health outcomes often prevent their use as first-line therapy. To date, a distinct mechanism of action for KDTs has not been determined and evidence suggests fatty acids (FAs) may play a role in eliciting anti-seizure effects. This dissertation aimed to provide insights into the effect of polyunsaturated fatty acids (PUFAs) and saturated fatty acids (SFAs) on seizure presence and severity through the analysis of dietary intake in a cohort of patients admitted to an epilepsy monitoring …

Categorization Of Orthologous Gene Clusters In 92 Ascomycota Genomes Reveals Functions Important For Phytopathogenicity, Daniel Peterson, Tang Li, Ana M. Calvo, Yanbin Yin

Food for Health: Publications

Phytopathogenic Ascomycota are responsible for substantial economic losses each year, destroying valuable crops. The present study aims to provide new insights into phytopathogenicity in Ascomycota from a comparative genomic perspective. This has been achieved by categorizing orthologous gene groups (orthogroups) from 68 phytopathogenic and 24 non-phytopathogenic Ascomycota genomes into three classes: Core, (pathogen or non-pathogen) group-specific, and genome-specific accessory orthogroups. We found that (i) ~20% orthogroups are group-specific and accessory in the 92 Ascomycota genomes, (ii) phytopathogenicity is not phylogenetically determined, (iii) group-specific orthogroups have more enriched functional terms than accessory orthogroups and this trend is particularly evident in phytopathogenic …

Linking The Brain And Bone Through Fat, Elisabeta Malinici, Anca Sirbu, Miruna Popa, Simona Fica

Journal of Mind and Medical Sciences

Over the past years, bone and adipose tissue have gained interest from researchers in the light of their secretory profiles, being able to produce active molecules, with the final effect of regulating energy homeostasis. Both adipocytes and osteoblasts originate in the pluripotent mesenchymal stem cell and this common origin has been proposed as the core of the fat-bone relationship. The central nervous system might be the third player in this association, capable of integrating signals. Numerous adipose tissue secreted factors that influence energy homeostasis and bone have been described: leptin, adiponectin, lipocalin 2, and inflammatory cytokines (e.g. IL-1, IL-6 and …
