Faculty, Staff and Students Publications

BACKGROUND: We sought to determine how a low fermentable oligosaccharide, disaccharide, monosaccharide, and polyol (FODMAP) diet (LFD) affected high FODMAP food intake, nutrient intake, and diet quality in children with functional abdominal pain disorders (FAPD).

METHODS: Children (ages 7-13 years) with Rome IV FAPD began a dietitian-guided LFD. Three-day food records were captured at baseline and 2-3 weeks into the LFD. Intake of high FODMAP foods, energy, macronutrients, micronutrients, food groups, and ultra-processed foods were determined.

KEY RESULTS: Median age of participants was 11 years, and 19/31 (61%) were female. Twenty-eight (90%) decreased high FODMAP food intake on the LFD: …

Crucial Nuances In Understanding (Mis)Associations Between The Neonatal Microbiome And Cesarean Delivery, Alexa M Sassin, Grace J Johnson, Alison N Goulding, Kjersti M Aagaard

Faculty, Staff and Students Publications

As rates of Cesarean delivery and common non-communicable disorders (NCDs), such as obesity, metabolic disease, and atopy/asthma, have concomitantly increased in recent decades, investigators have attempted to discern a causal link. One line of research has led to a hypothesis that Cesarean birth disrupts the presumed normal process of colonization of the neonatal microbiome with vaginal microbes, yielding NCDs later in life. However, a direct link between a disrupted microbiota transfer at time of delivery and acute and/or chronic illness in infants born via Cesarean has not been causally established. Microbiota seeding from maternal vaginal or stool sources has been …

From World War Ii To Covid-19: A Historical Perspective On The American Medical Supply Chain, Hunter D Bechtold, Andrea T Cruz, Brent D Kaziny

Faculty, Staff and Students Publications

COVID-19 is the latest episode of shortages of critical medical supplies. Historically and to the present day, medical supplies have been sourced from single regions in the world, thus rendering the supply chain vulnerable to a myriad of harmful circumstances. We argue that shortages in medications related and unrelated to COVID have illustrated the need for the United States to diversify its medical supply sources before future pandemics, political crises, or natural disasters occur.

BACKGROUND: Antimicrobial resistance is a global health threat. To slow resistance and preserve antibiotics, stewardship interventions are increasingly promoted and mandated. Urine cultures are the most common microbiological test in the outpatient setting. Contamination most likely occurs during urine collection from surrounding vaginal, perineal, and epidermal flora. Sample contamination can lead to incorrect diagnosis, unnecessary or inappropriate treatment, poor patient outcomes, and higher costs. Therefore, ensuring proper collection of urinary samples serves as a prime diagnostic stewardship target, one that international nursing societies increasingly endorse as an opportunity for nurse involvement.

OBJECTIVES: Determine the prevalence, predictors, and antibiotic prescribing associated …

Telomere Biology Disorders: Time For Moving Towards The Clinic?, Luis F Z Batista, Inderjeet Dokal, Roy Parker

2020-Current year OA Pubs

Telomere biology disorders (TBDs) are a group of rare diseases caused by mutations that impair telomere maintenance. Mutations that cause reduced levels of TERC/hTR, the telomerase RNA component, are found in most TBD patients and include loss-of-function mutations in hTR itself, in hTR-binding proteins [NOP10, NHP2, NAF1, ZCCHC8, and dyskerin (DKC1)], and in proteins required for hTR processing (PARN). These patients show diverse clinical presentations that most commonly include bone marrow failure (BMF)/aplastic anemia (AA), pulmonary fibrosis, and liver cirrhosis. There are no curative therapies for TBD patients. An understanding of hTR biogenesis, maturation, and degradation has identified pathways and …

Improving Hypertension Self Management In African American Men, Elizabeth C. Felix

Electronic Theses and Dissertations

Hypertension is a cardiopulmonary condition linked to genetic, environmental, and social factors. Left untreated, it can lead to fatal conditions such as heart disease. In the United States, African Americans experience disproportionately high rates of hypertension, earlier onset of symptoms, greater severity, and higher related mortality rates. African Americans also statistically have more difficulty self-managing their hypertension than other demographics. The aim of this project was (a) to identify, define, and measure perceived barriers to self-management of hypertension among African American men and (b) to target these barriers and increase patient engagement through personalized intervention plans. The researcher recruited 24 …

Functional Characterization Of Enhancer Activity During A Long Terminal Repeat's Evolution, Alan Y Du, Xiaoyu Zhuo, Vasavi Sundaram, Nicholas O Jensen, Hemangi G Chaudhari, Nancy L Saccone, Barak A Cohen, Ting Wang

2020-Current year OA Pubs

Many transposable elements (TEs) contain transcription factor binding sites and are implicated as potential regulatory elements. However, TEs are rarely functionally tested for regulatory activity, which in turn limits our understanding of how TE regulatory activity has evolved. We systematically tested the human LTR18A subfamily for regulatory activity using massively parallel reporter assay (MPRA) and found AP-1- and CEBP-related binding motifs as drivers of enhancer activity. Functional analysis of evolutionarily reconstructed ancestral sequences revealed that LTR18A elements have generally lost regulatory activity over time through sequence changes, with the largest effects occurring owing to mutations in the AP-1 and CEBP …
