Examining Associations Of Louisiana’S Gift Program And Race/Ethnicity With Breastfeeding Initiation And Duration Using Prams, Jennifer Le, Andrei Stefanescu, Marci Brewer, Betsy Dancisak, Rosaria Trichilo

Journal of the Louisiana Public Health Association

Background: The Gift is a program that helps Louisiana birthing facilities improve breastfeeding outcomes. Prior research shows that breastfeeding initiation and duration vary by race/ethnicity. We examined the associations of Gift designation and race/ethnicity with breastfeeding in Louisiana. Methods: We used 2016-2018 weighted Louisiana Pregnancy Risk Assessment Monitoring System (PRAMS) and birth data. Weighted chi-square tests and logistic regression models were used to examine the associations of Gift designation and race/ethnicity with breastfeeding initiation and duration. Results: Women delivering at Gift facilities were more likely to initiate breastfeeding compared to non-designated facilities (p < 0.0001). This association was stronger in Non-Hispanic White women (adjusted odds ratio (aOR) 1.76; 95% confidence interval (CI) 1.22-2.53) than in Non-Hispanic Black women (aOR 1.47; 95% CI 1.08-2.00). We did not find statistically significant associations with breastfeeding duration. Conclusions: Delivering at a Gift facility is beneficial for breastfeeding initiation regardless of race/ethnicity. However, racial disparities persist at Gift facilities.

Western North American forest ecosystems are experiencing rapid changes in disturbance regimes because of climate change and land use legacies (Littell et al. 2018). In many of these forests, the accumulation of surface and ladder fuels from a century of fire suppression, coupled with a warming and drying climate, has led to increases in the number of large fires (Westerling 2016) and the proportion of areas burning at higher severity (Safford and Stevens 2017, Singleton et al. 2018). While the annual area burned by fire is still below historical levels (Taylor et al. 2016), some forest types in the west …

Evaluating The Microbial Experience Influence On Anti-Tumor Immune Response, Jessica A. Ensing

Student Summer Scholars Manuscripts

Despite the steady increase of hygienic standards, the CDC continues to report an increase of immune-mediated diseases such as allergies and asthma. Human avoidance of microbial exposure and subsequently less experienced immune systems may be the cause for this increase. We investigated if increased microbial exposure results in increased immunity to cancer (B16 melanoma) by measuring activated lymphocytes between two groups of C57Bl/6 mice: specific pathogen free (SPF) mice (which had little microbial exposure) and cohoused (COH) mice (which were exposed to numerous microbes). Previous research shows that the CoH mouse model mimics a human adult’s immune system, while the …

Single-cell RNA-sequencing (scRNAseq) technologies are rapidly evolving. Although very informative, in standard scRNAseq experiments, the spatial organization of the cells in the tissue of origin is lost. Conversely, spatial RNA-seq technologies designed to maintain cell localization have limited throughput and gene coverage. Mapping scRNAseq to genes with spatial information increases coverage while providing spatial location. However, methods to perform such mapping have not yet been benchmarked. To fill this gap, we organized the DREAM Single-Cell Transcriptomics challenge focused on the spatial reconstruction of cells from the Drosophila embryo from scRNAseq data, leveraging as silver standard, genes with in situ hybridization …

Infection of rat pulmonary microvascular endothelial cells with the bacterium Pseudomonas aeruginosa induces the production and release of cytotoxic oligomeric tau and beta amyloid (Aβ). Here, we characterized these cytotoxic amyloids. Cytotoxic behavior and oligomeric tau were partially resistant to digestion with proteinase K, but cytotoxicity was abolished by various denaturants including phenol, diethylpyrocarbonate (DEPC), and 1,1,1,3,3,3-hexafluoro-2-isopropanol (HFIP). Ultracentrifugation for 8 h at 150 000 g was required to remove cytotoxic activity from the supernatant. Ultracentrifugation, DEPC treatment, and immunodepletion using antibodies against Aβ also demonstrated that cytoprotective protein(s) are released from endothelial cells during P. aeruginosa infection. Mass spectrometry …

Dissecting Drivers Of Basal Immunity And Acute Responses To Viral Infection, Aisha Nadia Hegab Souquette

Theses and Dissertations (ETD)

Heterogeneity in the human immune system can lead to limited vaccine efficacy, poor response to therapeutics, increased susceptibility to immune mediated diseases, and differential outcome to infection. Studies to date have suggested a role for biological, environmental, and genetic factors in immune variation; however, they are often focused on a specific subset of the population (e.g. ancestral group, age range) which can exclude phenotypes unique to a diverse population and bias results. To address this gap, we have utilized samples from healthy or influenza virus infected subjects from 8 distinct populations in 5 countries to conduct an integrative analysis of …

Model-Based Dose-Exposure-Response Assessment For Lead And Backup Spectinamide In A Mouse Model Of Tuberculosis, Santosh Janardan Wagh

Theses and Dissertations (ETD)

Despite decades of research, tuberculosis remains the oldest pathogen-based disease that is the leading cause of death from a single infectious agent. Among many anti-tubercular therapies under investigation, the semisynthetic compounds spectinamides are a promising novel class of anti-tuberculosis agents. One such lead candidate, spectinamide 1810, and backup spectinamide 1599 have demonstrated excellent efficacy, safety, and drug-like properties in various in vitro and in vivo assessments. The dose-ranging and dose fractionation studies were designed to characterize the dose-exposure-response relationship for lead and backup spectinamide in a mouse model of Mycobacterium tuberculosis infection. In this current study, we used 26 and …

Role Of Cerebral Vasculature And Effect Of Circulating Exosomes In Propagation Of Systemic Inflammatory Responses Into The Central Nervous System, Mahesh Chandra Kodali

Theses and Dissertations (ETD)

Sepsis-associated encephalopathy (SAE) is an acutely progressing brain dysfunction induced by systemic inflammation. The mechanism of initiation of neuroinflammation during SAE, which ultimately leads to delirium and cognitive dysfunction, remains elusive. The goal of this project was to study the molecular events of SAE to capture its onset and progression into the central nervous system (CNS), and further identify the cellular players involved in mediating acute inflammatory signaling. Gene expression profiling on the cerebral vessels isolated from the brains of the mice treated with peripheral lipopolysaccharide (LPS) revealed that the cerebral vasculature responds within minutes to acute systemic inflammation by …

The majority of ovarian cancer patients are already at an advanced stage when diagnosed. In addition, ovarian cancers often become chemoresistant and metastatic, and recur following initial chemotherapy.

Attenuation Of Interferon Responses In The Obese Host And Ramifications For Influenza Virus Evolution, Rebekah Reed Honce

Theses and Dissertations (ETD)

The most insidious pandemic of modern life does not arise from an infectious agent but rather from malnutrition. With its global incidence tripling over the past three decades, obesity is a major public health concern. Obesity’s rising prevalence has also illuminated its impact on communicable diseases. Following the 2009 H1N1 influenza A virus pandemic, obesity was identified as a risk factor for increased disease severity and mortality in infected individuals. Obesity causes a chronic state of meta-inflammation with systemic implications for immunity, including delayed antiviral responses to influenza virus infection, poor recovery, and impaired immunological memory. However, the majority of …

Vitamin D Levels Affect Survival In A Bcr-Abl Acute Lymphoblastic Leukemia Mouse Model But Do Not Cause Vitamin-Drug Interactions, Kavya Annu

Theses and Dissertations (ETD)

It is a well-established phenomenon that dietary components containing CYP3A inducers or inhibitors if co-administered with drugs that are CYP3A4 substrates lead to marked drug-drug interactions. Because vitamin D is known to regulate intestinal CYP3A expression and gut CYP3A expression plays an important role in pre-systemic metabolism of CYP3A drugs, we determined the impact of vitamin D (VD3) status on systemic exposure and efficacy of chemotherapeutic agents that are CYP3A substrates. We employed VD3 sufficient and deficient mice to perform pharmacokinetics (PK) and anti-leukemic efficacy studies.

First, using hCYP3A4 transgenic mouse model we evaluated the intestinal, hepatic and renal expression …

Genetic Variation And Sex Mediate Differential Responses To ∆-9-Tetrahydrocannabinol Among Inbred Mice, Cory Parks

Theses and Dissertations (ETD)

The plant Cannabis sativa has been used by people for both recreational and medicinal use for thousands of years, but scientific investigation of the plant and its components didn’t begin until the early nineteen hundreds when Cannabis components known as phytocannabinoids were characterized and later isolated. In the 1970’s, ∆9-tetrahydrocannabinol (THC) was isolated and recognized as the major constituent responsible for the psychoactive and intoxicating effects associated with consumption of cannabis. This opened the door for intensive research in the field that lead to the discovery of the endogenous cannabinoid system and its associated receptors, effectors of signaling, and biosynthetic …
