Incident Tuberculosis Diagnoses In Children At High Risk For Disease, Milagros Wong, Julia M. Coit, Milagros Mendoza, Silvia S. Chiang, Helen Marin, Jerome T. Galea, Leonid Lecca, Molly F. Franke

Social Work Faculty Publications

We followed 35 children meeting a research definition for unconfirmed tuberculosis (TB) but in whom a pediatric pulmonologist did not diagnose or treat TB. After a median follow-up of 16.4 months, most children were not diagnosed with TB following a comprehensive evaluation. However, 2 were diagnosed with TB, demonstrating high TB risk (6%; exact 95% CI, 1%–19%). In some contexts, researchers may wish to supplement these research definitions with clinical decision data and longitudinal follow-up in order to improve specificity.

The following protocol describes our workflow for processing wastewater with the goal of detecting the genetic signal of SARS-CoV-2. The steps include pasteurization, virus concentration, RNA extraction, and quantification by RT-qPCR. We include auxiliary steps that provide new users with tools and strategies that will help troubleshoot key steps in the process. This protocol is one of the safest, cheapest, and most reproducible approaches for the detection of SARS-CoV-2 RNA in wastewater. Furthermore, the RNA obtained using this protocol, minus the pasteurization step, can be sequenced both using a targeted approach sequencing specific regions or the whole genome. The protocol …

Premarital Fertility And Marital Timing In Malawi, Michelle Poulin, Kathleen Beegle, Hongwei Xu

Publications and Research

In Malawi, Africa, the median age at first marriage is among the lowest on the continent and adolescent fertility rates are among the highest. Using high-frequency panel data from the country designed to follow single women and men into marriage, we examine the extent to which premarital fertility is associated with the timing of marriage. Two notable findings emerge. First, premarital fertility typically leads to a more rapid transition into marriage, compared to those not having had a premarital conception or birth, with controls. The effect is as strong for men as it is for women. Second, among women with …

Toward Transformable Photonics: Reversible Deforming Soft Cavities, Controlling Their Resonance Split And Directional Emission, Mark Douvidzon, Shai Maayani, Harel Nagar, Tamir Admon, Vladimir Shuvayev, Lan Yang, Lev Deych, Yael Roichman, Tal Carmon

Publications and Research

We report on reversible and continuously deformable soft micro-resonators and the control of their resonance split and directional emission. Assisted by computerized holographic-tweezers, functioning as an optical deformer of our device, we gradually deform the shape and change the functionality of a droplet whispering-gallery cavity. For example, we continuously deform hexagonal cavities to rectangular ones and demonstrate switching to directionally emitting mode-of-operation, or splitting a resonant mode to a 10-GHz separated doublet. A continuous trend of improving spatial light modulators and tweezers suggests that our method is scalable and can control the shape and functionality of many individual devices. We …

Bird Abundance And Diversity And The Impact Of Oyster Reef Restoration On The Bird Community In Mosquito Lagoon, Florida, Usa, Jessica Copertino

Electronic Theses and Dissertations, 2020-2023

Birds are often used as indicators for biodiversity and ecosystem health. While birds have been monitored in other parts of the Indian River Lagoon (IRL), there has been little research on birds in Mosquito Lagoon (ML, the northernmost portion of the IRL). This thesis first examines the abundance and diversity of birds in ML by using two years of photographic observations to assess seasonal variations and the use of various habitat features by specific bird taxa. Abundance and species richness were highest in winter, while evenness and Simpson's diversity were highest in summer. Moreover, natural and artificial habitat features were …

Forensic Implications For The Diagenetic Alteration Of The Stable Isotopic Composition Of Pig Ribs Following Exposure To Aqueous Conditions., Erin Martin

Electronic Theses and Dissertations, 2020-2023

This research involves the examination of the contribution of stable isotope analysis to the forensic anthropological objective of human identification. Oxygen isotopes, which vary in water in a predictable manner according to climatological and geographical factors, can be used to determine the region of origin of an unidentified individual following isotopic analysis of human skeletal remains. However, stable oxygen isotopes from human remains recovered from various aqueous environments may be altered by diagenetic processes that occur following deposition. The focus of this research is to determine potential diagenetic changes in the oxygen isotopic value (d18O) of Sus scrofa (domestic pig) …

Non-Lethal Predictors Of Organ Level Metal Contaminants In Central Florida Red-Shouldered Hawks, Jennifer Bouchenot

Electronic Theses and Dissertations, 2020-2023

Elemental contaminants aggregate in the environment due to human activity and can induce detrimental physiological effects within organisms. Birds exhibit exceptional susceptibility to many pollutants and are popular biomonitoring agents throughout the world. Birds of prey are of special interest due to their substantial biomagnification potential. Lethal sampling of internal organs yields accurate contaminant measurements, but recent sampling trends are endeavoring towards non-destructive sampling such as feathers. This methodological shift stems from researchers' preference for less-regulated samples, enhanced animal welfare, and broadening the possible collaborative audience with simpler protocols. Unfortunately, investigations of feathers have shown that their accuracy is capricious …

Modulation Of Fat Taste By Diet And Hormones, Ashley Calder

Electronic Theses and Dissertations, 2020-2023

The prevalence of obesity worldwide continues to rise despite efforts to reverse the trend. While many factors contribute to the onset and maintenance of obesity, caloric intake and dietary composition have been shown be primary contributors. The oral cavity is one of the first systems to encounter food and determine its hedonic value. As the gateway to ingestion, the taste system plays a unique role in the initial decisions surrounding the control of food intake. Nutrients like carbohydrates, protein, minerals, and fat all have dedicated systems to allow their recognition at this outermost site of the enteric nervous system. Recent …

Transcriptomic Analyses Reveal Distinct Responses Of Differentiated And Poorly-Differentiated Intestinal Epithelial Cells To Lipid Peroxides, Nisreen Faizo

Electronic Theses and Dissertations, 2020-2023

Lipid peroxides (LOOHs) abound in processed food and have been implicated in the pathology of diverse diseases including gut, cardiovascular, and cancer diseases. However, the molecular mechanisms by which LOOHs contribute to disease have not been fully characterized. Caco-2 cells have been widely used to model human intestinal epithelium in metabolic studies. As differentiated (Diff) and poorly-differentiated (PDiff) Caco-2 cells represent good models of human enterocytes and intestinal tumor cells, respectively, we investigated the cellular response of Diff and PDiff Caco-2 cells to the most common dietary LOOH, 13-hydroperoxyoctadecadienoic acid (13-HPODE), in terms of differential gene expression, gene ontology and …

Bioarchaeological And Mortuary Patterns At Holtun, Guatemala: Integrating A Comparative Osteobiographic Approach, Horvey Palacios

Electronic Theses and Dissertations, 2020-2023

Bioarchaeological analysis can help identify patterns of mortuary ritual and social experience of ancient Maya peoples. However, there is limited bioarchaeological and mortuary evidence for the relationship between the development of social complexity and social experience. Particularly, how is social organization reflected in patterns of burial practice and skeletal markers of stress. This thesis uses osteobiographies to contextualize the mortuary and biological profiles of 20 individuals interred at the Maya site of Holtun, Guatemala to examine bioarchaeological variation during the Preclassic (800 B.C. – 250 A.D.) and Late Classic (550 A.D. – 900 A.D.) periods. This work highlights the integration …

A Longitudinal Examination Of Depression Among Older Adults: The Role Of Working Memory And Sleep, David Brush

Electronic Theses and Dissertations, 2020-2023

Introduction: The development and regulation of depressive symptoms and the ability to regulate their development is a complex process. Both working memory and sleep disturbance relates to depressive symptom endorsement, though the mechanisms relating these variables have not been examined longitudinally. The current manuscript contains a series of three interrelated studies that aim to elucidate the relationship between potential emotion regulation resources longitudinally within the context of the Selection, Optimization, and Compensation of Emotion Regulation (SOC-ER) model. Study one examined the temporal relationship between working memory and depression, study two examined working memory and depression following loss of spouse, and …

Analysis Of Sexual Lubricants As A Form Of Trace Evidence For Sexual Assault Cases, Brooke Baumgarten

Electronic Theses and Dissertations, 2020-2023

A major gap in sexual assault casework is demonstrated when DNA is not recovered. Oftentimes, if DNA evidence is not present on the collection swabs, the sexual assault kit (SAK) is not further analyzed. Due to the "CSI effect," DNA is commonly understood as highly identifiable evidence, potentially leading to increased condom usage to eliminate or reduce DNA transfer during a sexual assault. Therefore, the analysis of condoms and sexual lubricants is pertinent. The purpose of this research is to develop analytical protocols to potentially connect unknown substances recovered in a SAK to known lubricant reference samples. Sexual lubricants were …

Maternal Cannabis Use Is Associated With Suppression Of Immune Gene Networks In Placenta And Increased Anxiety Phenotypes In Offspring, Gregory Rompala, Yoko Nomura, Yasmin L. Hurd

Publications and Research

While cannabis is among the most used recreational drugs during pregnancy, the impact of maternal cannabis use (mCB) on fetal and child development remains unclear. Here, we assessed the effects of mCB on psychosocial and physiological measures in young children along with the potential relevance of the in-utero environment reflected in the placental transcriptome. Children (~3-6 years) were assessed for hair hormone levels, neurobehavioral traits on the behavioral assessment system for children (BASC-2) survey, and heart rate variability (HRV) at rest and during auditory startle. For a subset of children with behavioral assessments, placental specimens collected at birth were processed …

Foster Parents' Knowledge And Perceptions Of Behavior And Behavior Management In Children With Adverse Childhood Experiences, Shelby Freeman

Undergraduate Honors Theses

Circumstances that lead to placement in foster care and even the experience of foster care itself can be traumatic to children. These negative events and others, including abuse, neglect, and parental separation/divorce, are considered adverse childhood experiences (ACEs) {American Academy of Pediatrics, n.d.). Approximately 90% of all foster children have experienced one or more ACEs before or during their time in foster care (Dorsey et al., 2011). The emotional and physical impact that AC Es have on children can change the chemistry of their brain, which influences several key areas ofa child's development. Depending on the number and severity of …

Isocitrate Dehydrogenase-1 Mutation As A Prognostic Factor In Recurrent Glioblastoma, Haroon R. Hashmi

Walden Dissertations and Doctoral Studies

Glioblastoma (GBM) is an aggressive form of brain cancer that has a high recurrence rate and very poor prognosis. The prognostic value of various molecular markers (e.g., IDH 1 mutation, MGMT promoter methylation, etc.) and clinical factors (e.g., age, KPS, surgery and chemotherapy) has been studied in GBM after initial diagnosis but not as extensively in the recurrent GBM. Utilizing a retrospective cohort design, based on quantitative data collected through medical chart reviews, and the conceptual framework of outcomes research in oncology, this study evaluated the prognostic value of IDH-1 mutation in recurrent GBM in the context of key predictor …

However, the effects that lack of opportunities for advancement has on women’s motivation and workplace attitude have not been thoroughly addressed. The purpose of this qualitative study was to explore the experiences of women working at a large emergency management organization, specifically how perceptions of the glass ceiling affected their motivation and attitude in the workplace. The research questions were focused on gender limitations in career advancement, motivational factors, including extrinsic and intrinsic, and the morale of women who had experiences with gender …

Hospice Social Workers In The Death With Dignity Process, Lisa M. Carter

Walden Dissertations and Doctoral Studies

Hospice social workers are in an ethical conundrum due to the contrast between honoring clients’ self-determined life closure and hospice organization prescribed non-participation in requests for physician-assisted death. The National Hospice and Palliative Care Association and the International Hospice and Palliative Care Association have issued position statements that the hospice philosophy of care is to provide comfort and reduce suffering, not to hasten death. Social workers are bound by a code of ethics to honor patient choice in end-of-life decisions. This generic qualitative study gives voice to hospice social workers in the Pacific Northwest regarding their motivations and responses to …

The Impact Of Midwifery On Infant And Maternal Outcomes Among Black Mothers, Joann Honoré

Walden Dissertations and Doctoral Studies

According to recent studies, disparities are prevalent in maternal and fetal outcomes between Black and White mothers in the United States. Researchers have established that using a midwife versus other healthcare practitioners can elicit positive maternal and fetal outcomes for Black mothers. However, no within-race research has been conducted exploring midwifery as an insulating factor against these disparities. The purpose of this quantitative retrospective cohort study was to explore the impact of midwifery on infant and maternal outcomes compared to outcomes associated with other prenatal care models/caregivers among Black mothers in California using secondary data. The ecological model was used …
