Perinatal Buprenorphine Effects On Offspring Growth, Opioid Withdrawal, And Brain Morphology In Rats, Parker Barnes

Electronic Theses and Dissertations

Opioid use disorder (OUD) impacts 5.6 million people in the US. Buprenorphine (BUP) is a commonly prescribed opioid medication used to treat OUD, including in pregnant women. However, opioid use during pregnancy is associated with poorer infant outcomes including reduced fetal growth, neurodevelopmental deficits, and neonatal opioid withdrawal syndrome (NOWS). Recent clinical data suggests that providing mothers with a lower dose of BUP may result in fewer negative outcomes in infants. Here, a preclinical rodent model of low-dose perinatal BUP exposure was used to study offspring health outcomes in the neonate, juvenile, and adolescent offspring. Dams were given clinically relevant …

Investigating The Developmental Impacts Of 3,3’-Dichlorobiphenyl (Pcb-11) In Zebrafish (Danio Rerio), Monika A. Roy

Doctoral Dissertations

The environmental pollutant 3,3’-dichlorobiphenyl (PCB-11) is a lower-chlorinated polychlorinated biphenyl (PCB) congener present in air and water samples. Both PCB-11 and its metabolite, 4-PCB-11-Sulfate, are detected in humans, including in pregnant women. The work conducted for this dissertation takes a developmental toxicology approach and uses zebrafish (Danio rerio) to investigate PCB-11’s potential impacts to the liver and pancreas. Chapter 1 introduces PCBs and the current knowledge gaps. Chapter 2 investigates PCB-11 interactions in short-term 4-day exposures with the Aryl hydrocarbon receptor (Ahr) pathway in both 0-20 mM individual and mixture exposures with other Ahr agonists. In Chapter 3, …

Screening For Iron-Deficiency Anemia In The Pediatric Population (Ages 1-17) In Gonaïves, Haiti, Cara Rose Fratianni

Doctor of Nursing Practice Final Manuscripts

Abstract

Purpose: The purpose of this pilot project is to screen for iron-deficiency anemia in pediatric patients (ages 1-17) in a primary school in Gonaïves, Haiti. Patients with anemia will be treated with oral supplemental iron for a period of four weeks according to WHO guidelines (WHO, 2011). All students will be treated empirically for helminths per WHO guidelines, unless treated elsewhere in the last six months (WHO, 2017). Nutritional status will also be assessed using MUAC according to WHO guidelines (2017).

Background Summary: Malnutrition contributes significantly to the problem of iron-deficiency anemia, with one in four children exhibiting stunting …

Carbohydrates And Fungal Toxin Exposure Influence The Vaginal Microbiota, Metabolome, And Reproductive Health Of Women, Stephanie L. Collins

Electronic Thesis and Dissertation Repository

The reproductive health of women is influenced by microorganisms and their metabolites, namely those representing the vaginal microbiota and those producing toxins that are ingested. To manipulate the vaginal microbiota toward a health-associated, Lactobacillusdominant state, an approach adopting prebiotic lactulose was taken. Using batch culture, lactulose supported Lactobacillus maintenance and positively altered metabolites, while not disrupting indigenous L. crispatus epithelial adherence. The vagina also harbours abundant glycogen, but initial assumptions that lactobacilli utilize it were incorrect. I have now shown that glycogen selectively stimulates organisms associated with dysbiosis and L. iners in a self-limiting manner. Other compounds such as environmental …
