Preventing Allergies In Infants: What Foods To Introduce And When, Annika Israelsen, Stacy Bevan, Mateja R. Savoie-Roskos

All Current Publications

Food allergies have become increasingly common over the past several years among children in the United States (Comberiati et al., 2019; Sicherer et al., 2017). Food allergies are a negative immune response occurring in the body after eating a specific food (Sicherer et al., 2017). Unlike food intolerances, such as lactose intolerance which causes uncomfortable symptoms in the stomach and intestines, allergic reactions to food can cause a wide range of serious and sometimes fatal symptoms (Konek & Becker, 2020). Food allergies can affect a child’s health and quality of life, while also impacting their caregivers’ lives (Sicherer et al., …

Β-Cell Impairment And Clinically Meaningful Alterations In Glycemia In Obese Youth Across The Glucose Tolerance Spectrum, Joon Young Kim, Hala Tfayli, Fida Bacha, Sojung Lee, Nour Gebara, Silva Arslanian

Children’s Nutrition Research Center Staff Publications

Background/aims: In obese youth, it is not clear what degree of β-cell impairment translates to glucose dysregulation commensurate with shifts from normal glucose tolerance (NGT) to impaired glucose tolerance (IGT) to type 2 diabetes. We aimed to investigate the quantitative relationship between β-cell (clamp-measured disposition index [DI]) and OGTT glucose area under the curve (G-AUC) in obese youth across the spectrum of glucose tolerance.

Methods: Data from 152 youth (58 African-American [AA] and 94 American-White [AW]; 73 NGT, 48 IGT, and 31 type 2 diabetes) who completed a 3-h hyperinsulinemic (80 mu/m2/min)-euglycemic clamp, and a 2-h hyperglycemic (225 mg/dL) clamp …

Modeling Age-Dependent Developmental Changes In The Expression Of Genes Involved In Citrulline Synthesis Using Pig Enteroids, Mahmoud A Mohammad, Inka C Didelija, Barbara Stoll, Douglas G Burrin, Juan C Marini

Children’s Nutrition Research Center Staff Publications

metabolism of citrulline and arginine are well characterized. Enteroids, a novel ex-vivo model that recreates the three-dimensional structure of the intestinal crypt-villus unit, have shown to replicate molecular and physiological profiles of the intestinal segment from where they originated ("location memory").

Objective: The present study tested the hypothesis that enteroids recapitulate the developmental changes observed in vivo regarding citrulline production in pigs ("developmental memory").

Methods: Preterm (10- and 5-d preterm) and term pigs at birth, together with 7- and 35-d-old pigs were studied. Gene expression was measured in jejunal samples and in enteroids derived from this segment. Whole body citrulline …

The Effect Of Dietary Nitrate And Vitamin C On Endothelial Function, Oxidative Stress And Blood Lipids In Untreated Hypercholesterolemic Subjects: A Randomized Double-Blind Crossover Study, Reem Basaqr, Michealia Skleres, Rani Jayswal, D. Travis Thomas

Athletic Training and Clinical Nutrition Faculty Publications

BACKGROUND: Vitamin C may enhance nitric oxide (NO) production through stepwise reduction of dietary nitrate (NO₃) to nitrite (NO₂) to NO. The combined effect of vitamin C and NO₃ supplementation is relatively unexplored in untreated hypercholesterolemia.

AIMS: We aimed to examine whether co-administration of vitamin C and nitrate for 4-weeks would improve endothelial function (primary outcome), plasma NO metabolites, oxidative stress, and blood lipids (secondary outcomes).

METHODS: Subjects 50–70 years of age with low density lipoprotein (LDL) > 130 mg/dL and RHI ≤ 2 were enrolled in this randomized double-blind crossover study. Subjects were assigned to …

Investigation Of Surrogate Biomarkers Associated With Macular Pigment Status In A Group Of Older Irish Adults, Grainne Scanlon, John S. Butler, Daniel Mccartney, Ekaterina Lostutova, Rose Anne Kenny, James Loughman

Articles

SIGNIFICANCE: Macular pigment (MP) confers potent antioxidant and anti-inflammatory effects at the macula; however, its optical density in the eye is not routinely measured in clinical practice.

PURPOSE: This study explored a range of surrogate biomarkers including anthropometric, clinical, and plasma measures that may be associated with lower MP optical density (MPOD).

METHODS: Two thousand five hundred ninety-four subjects completed a full MP assessment as part of wave 1 of The Irish Longitudinal Study of Aging. Macular pigment optical density was measured using customized heterochromatic flicker photometry. Clinical (blood pressure), plasma (lipoproteins, inflammatory markers), and anthropometric (waist, hip, height, weight) …

Weight Status Of Children Aged 2-5 Years Old, Attending A Paediatric Outpatient Clinic And Its Association With Parental Feeding Style And Parental Perceptions Of Weight Status, Aisling Lee, Helen Callaghan, Dara Gallagher Dr, Annette Lalor, Louise Rattigan, Hilary Greaney, Laura Keaver

SURE Journal: Science Undergraduate Research Experience Journal

Background: A child’s weight status can allow health care professionals to assess their developmental growth. A child having a low or high weight for height could be due to an imbalance in nutrient intake occurring. It is important to balance dietary intake and physical activity to maintain a healthy weight status. Excessive consumption of food can lead to an overweight/obese weight status which is linked to non-communicable diseases. Parental feeding style can directly impact a child’s set of eating behaviours. Therefore, parents have a strong influence over a child’s growth pattern. In addition, parental awareness of childhood obesity is reported …

The Female Athlete Triad In Adolescent Athletes, Elise Withers, Mateja R. Savoie-Roskos, Stacy Bevan, Katie N. Brown

All Current Publications

The number of teenage girls participating in sports has dramatically increased in the last few decades (Brown et al., 2017). With increased sports participation, the positive effects of physical activity have become obvious (Thein-Nissenbaum & Hammer, 2017). However, a set of health-related problems specific to female athletes, known as the female athlete triad (triad), has emerged. This fact sheet will cover what the triad is, why the triad occurs, and triad prevention and treatment.

A secondary aim of the study was to examine if cultural competency training is provided in the university curriculum for prospective nutrition professionals in their role as interdisciplinary team members/leaders. There was a paucity of literature directed at the importance of university curricular providing cultural competency training for students in preparation for their role as the nutrition expert on multidisciplinary teams. The quantitative study was a non-experimental survey method. The study’s participant sample was …

Proposals For Upper Limits Of Safe Intake For Methionine, Histidine, And Lysine In Healthy Humans, Luc Cynober, Dennis M Bier, Patrick Stover, Motoni Kadowaki, Sidney M Morris, Rajavel Elango, Miro Smriga

Children’s Nutrition Research Center Staff Publications

Based on research presented during the 10th Amino Acid Assessment Workshop, no observed adverse effect levels (NOAELs) for supplemental methionine at 46 mg/(kg·d) (∼3.2 g/d), for supplemental histidine at 8.0 g/d, and for supplemental lysine at 6.0 g/d have been proposed. These NOAELs are relevant to healthy adults and are applicable only to high-purity amino acids administered in fortified foods or dietary supplements. Because individuals are exposed to the above supplemental amino acids in the context of complex combinations of essential amino acids or individually in dietary supplements for various physiologic benefits, such as body fat reduction, skin conditioning, mental …

The Central Melanocortin System And Human Obesity, Yongjie Yang, Yong Xu

Children’s Nutrition Research Center Staff Publications

The prevalence of obesity and the associated comorbidities highlight the importance of understanding the regulation of energy homeostasis. The central melanocortin system plays a critical role in controlling body weight balance. Melanocortin neurons sense and integrate the neuronal and hormonal signals, and then send regulatory projections, releasing anorexigenic or orexigenic melanocortin neuropeptides, to downstream neurons to regulate the food intake and energy expenditure. This review summarizes the latest progress in our understanding of the role of the melanocortin pathway in energy homeostasis. We also review the advances in the identification of human genetic variants that cause obesity via mechanisms that …

Beyond Clinical Food Prescriptions And Mobile Markets: Parent Views On The Role Of A Healthcare Institution In Increasing Healthy Eating In Food Insecure Families., Emily Dewit, Emily Meissen-Sebelius, Robin P. Shook, Kimberly Pina, Evelyn Donis De Miranda, Michelle J. Summar, Emily A. Hurley

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Children in food-insecure families face increased barriers to meeting recommendations for fruit and vegetable consumption. Hospitals and pediatric healthcare institutions have attempted to alleviate food-insecurity through various internal programs like food prescriptions, yet little evidence for these programs exist. Consistent with a patient-centered perspective, we sought to develop a comprehensive understanding of barriers to fruit and vegetable consumption and a parent-driven agenda for healthcare system action.

METHODS: We conducted six qualitative focus group discussions (four in English, two in Spanish) with 29 parents and caregivers of patients who had screened positive for food-insecurity during visits to a large pediatric …

Does Gender Moderate The Relationship Among Festival Attendees' Motivation, Perceived Value, Visitor Satisfaction, And Electronic Word-Of-Mouth?, Jeongyeon Jennie Ahn, Eun Kyong Cindy Choi, Hyun Woo Joung

Faculty and Student Publications

© 2020 by the authors. Festivals are experiential products heavily depending on the recommendations of previous visitors. With the power of social media growing, understanding the antecedents of positive electronic word-of-mouth (eWOM) intentions of festival attendees is immensely beneficial for festival organizers to better promote their festivals and control negative publicity. However, there is still limited research regarding eWOM intentions in the festival context. Thus, this study aims to fill such a gap by investigating the relationships among festival attendees' enjoyment seeking motivation, perceived value, visitor satisfaction, and eWOM intention in a local festival setting. Additionally, the moderating role of …

Fat And Fat-Free Mass Index References In Children And Young Adults: Assessments Along Racial And Ethnic Lines, Roman J Shypailo, William W Wong

Children’s Nutrition Research Center Staff Publications

Background: Fat-free mass index (FFMI) and fat mass index (FMI) are superior to BMI and fat percentage in evaluating nutritional status. However, existing references fail to account for racial/ethnic differences in body composition among children.

Objectives: Our goal was to produce age-based normative references for FFMI and FMI in children for specific racial/ethnic groups.

Methods: Body composition, weight, and height were measured in 1122 normal healthy children aged 2-21 y. Bone mineral content measured by DXA, total body water by deuterium dilution, and total body potassium by whole-body γ counting were combined to calculate fat-free mass (FFM) and fat mass …
