Department of Public Health Scholarship and Creative Works

The introduction of fluids other than breast milk during the first few days of life or later neonatal period has been identified as a risk factor for suboptimal breastfeeding (BF) outcomes in numerous studies using varying study designs. However, the relationship between early introduction of fluids other than breast milk and BF outcomes has not been systematically assessed using only prospective studies that can establish temporality, which is critical for determining whether observed associations are causal. We conducted a systematic review and meta-analysis of prospective studies to assess if there is a difference in BF outcomes as a result of …

The Role Of Aryl Hydrocarbon Receptor Activation On Immunoglobulin A-Secreting B Cell Gut Homing, Linda Ortiz

Master's Theses

Within the United States, foodborne diseases are estimated to result in more than 100,000 hospitalizations each year with 3,000 fatalities. Acute gastroenteritis impacts more than 1.5 million children each year in the United States. Worldwide, childhood morbidity and mortality are largely attributed to infectious diarrheal diseases. To combat infection at mucosal surfaces, immunoglobulin (Ig) A is produced by antibody-secreting B cells to inhibit and neutralize pathogens and their toxins. B cells are influenced by various extrinsic signals through activation of the aryl hydrocarbon receptor (AhR). The AhR is a ligand-activated transcription factor that links diet and environmental factors to intestinal …

Inter-Agency Collaborations Among Mental Health And Law Enforcement Professionals In San Bernardino County During Covid-19: A Qualitative Study, Sonya Mcisaac

Electronic Theses, Projects, and Dissertations

As first responders, law enforcement officers and mental health professionals are constantly sought after regarding the delivery of critical services to people in need. However, the COVID-19 pandemic brought almost everything to a halt. It is therefore important to understand how social services were delivered during the crisis. It has been assumed in the literature that interprofessional collaboration is an important service delivery framework. However, because COVID-19 is a relatively recent public health phenomenon, relevant studies on interprofessional collaboration between law enforcement officers and mental health professionals are scant, if not non-existent. This qualitative study addresses this gap by exploring …

Dental Students' Perceptions Of Dental Hygienists' Education And Scope Of Practice, Cynthia Metzger

Electronic Theses and Dissertations

Oral health is strongly correlated to systemic health in the United States. Dental professionals play a significant role in addressing the oral health and prevention of disease for populations in the United States. Because many areas in the United States lack access to dental care, the federal government considers dental hygienists part of the solution. It is now paying attention to restrictive dental hygiene scope of practice rules in each state. State dental boards, comprised mainly of dentists, make these rules based on their perception of dental hygienists' lack of education. This study explored fourth-year dental students' perceptions of the …

Knockdown Of C. Elegans Nad Kinases Nadk-1 Or Nadk-2 Induces An Antioxidant Response Without Affecting Lifespan, Henry Gong

Electronic Theses and Dissertations

Nearly all multicellular organisms show changes in redox balance with aging leading to oxidative damage of macromolecules. This study investigated the role of the [NADP⁺]/[NADPH] redox couple in aging. This redox couple plays an important role in maintaining tissue redox balance and becomes slightly more oxidized in aged tissues. NADPH is a major source of reducing equivalents for enzymes that detoxify hydrogen peroxide. However, catalase detoxifies hydrogen peroxide independently of NADPH. But catalase is absent from mitochondria, a major source of hydrogen peroxide, where instead glutathione plays the major role in hydrogen peroxide detoxification in an NADPH-dependent manner. …

Risk-Prone And Risk-Averse Foraging Strategies Enable Niche Partitioning By Two Diurnal Orb-Weaving Spider Species, Mitchell D. Long

Electronic Theses and Dissertations

Niche partitioning is a major component in understanding community ecology and how ecologically similar species coexist. Temporal and spatial partitioning and differences in foraging strategy, including sensitivity to risk (variance), likely contribute to partitioning as well. Here, we approach this partitioning with fine resolution to investigate differences in overall strategy between two species of diurnal, orb-weaving spiders, Verrucosa arenata and Micrathena gracilis (Araneae: Araneidae), that share similar spatial positioning, temporal foraging window, and prey. Through field observation, we found that V. arenata individuals appear to increase spatial and temporal sampling to compensate for an overall risk-prone strategy that depends on …

The Restaurant Meals Program: A Guide For New York State’S Successful Implementation, Evan Cohen

Theses

In October 2021, New York State (NYS) Governor Kathy Hochul signed into law legislation enacting the Restaurant Meals Program (RMP) to the Supplemental Nutrition Assistance Program (SNAP).
