Post-Partum Depression (Ppd) Screening Tools Effectiveness In Refugee Populations, Joshua Jensen

Annual Research Symposium

Purpose:

Immigrant mothers check all the boxes that are significant risk factors for developing or exacerbating Postpartum Depression (PPD). These risk factors include, suffering in solitude, cultural conceptualizations, barriers to help seeking, and a lack of facilitators to help seeking. Despite this very little research has been done to find effective screening methods for this population.

The purpose of this research project is to compile the works of those before me to determine whether the Edinburgh Postnatal Depression or the PHQ 9 screening tool is the most effective for immigrant mothers.

Methods:

Glucose 6-P Dehydrogenase Overexpression Improves Aging-Induced Endothelial Dysfunction In Aorta From Mice: Role Of Arginase Ii, Eva Serna, Maria D Mauricio, Teresa San-Miguel, Sol Guerra-Ojeda, David Verdú, Alicia Valls, Coralie Arc-Chagnaud, Adrián De La Rosa, José Viña

Faculty, Staff and Student Publications

The increase of vascular arginase activity during aging causes endothelial dysfunction. This enzyme competes with the endothelial nitric oxide synthase (eNOS) for L-arginine substrate. Our hypothesis is that glucose 6-P dehydrogenase (G6PD) overexpression could improve the endothelial function modulating the arginase pathway in aorta from mice. For this study, three groups of male mice were used: young wild type (WT) (6-9 months), old WT (21-22 months) and old G6PD-Tg (21-22 months) mice. Vascular reactivity results showed a reduced acetylcholine-dependent relaxation in the old WT but not old G6PD-Tg group. Endothelial dysfunction was reverted by nor-NOHA, an arginase inhibitor. Mice overexpressing …

Department of Paediatrics and Child Health

In the field of rare diseases, progress in molecular diagnostics led to the recognition that variants linked to autosomal-dominant neurodegenerative diseases of later onset can, in the context of biallelic inheritance, cause devastating neurodevelopmental disorders and infantile or childhood-onset neurodegeneration. TOR1A-associated arthrogryposis multiplex congenita 5 (AMC5) is a rare neurodevelopmental disorder arising from biallelic variants in TOR1A, a gene that in the heterozygous state is associated to torsion dystonia-1 (DYT1 or DYT-TOR1A), an early-onset dystonia with reduced penetrance. While 15 individuals with TOR1A-AMC5 have been reported (less than 10 in detail), a systematic investigation of the full disease-associated spectrum has …

Pulse Oximetry: Why Oxygen Saturation Is Still Not A Part Of Standard Pediatric Guidelines In Low-And-Middle-Income Countries (Lmics), Maheen Sheikh, Huzaifa Ahmad, Romesa Ibrahim, Muhammad Imran Nisar, Fyezah Jehan

Department of Paediatrics and Child Health

Background: With the high frequency of acute respiratory infections in children worldwide, particularly so in low-resource countries, the development of effective diagnostic support is crucial. While pulse oximetry has been found to be an acceptable method of hypoxemia detection, improving clinical decision making and efficient referral, many healthcare set ups in low- and middle-income countries have not been able to implement pulse oximetry into their practice.
Main body: A review of past pulse oximetry implementation attempts in low- and middle-income countries proposes the barriers and potential solutions for complete integration in the healthcare systems. The addition of pulse oximetry into …

Mental health related symptoms and associated experiences in the perinatal period present challenges, particularly regarding identification and appropriate management. Perinatal Mental Health (PMH) screening occurs in clinical settings on a more regular basis than ever before thanks to validated screening measures used at perinatal visits; however, pregnant and parenting individuals report several concerns when completing these screeners and providers report barriers in addressing resultant findings. To address barriers and enhance the PMH screening experience, this team of clinicians and researchers propose a tool – the PMH Connect: a Perinatal Mental Health Screening Connection, Education, and Decision Aid – to be …

Impact Of Treating Maternal Periodontal Disease On The Risk Of Preterm Birth And Low Birth Weight: An Umbrella Review Of Systematic Reviews, May Salama, Abdullah Al-Taiar

College of Health Sciences Posters

Pregnancy involves complex physical and hormonal changes that significantly impact almost every organ system, including the oral cavity. The presence of oral disease in women has consequences for both their child and their health. The two main oral conditions linked to pregnancy are gingivitis and periodontal disease. Several studies have demonstrated that there is a positive association between periodontal disease and adverse pregnancy outcomes such as preterm birth (PTB) and low birth weight (LBW). PTB and LBW are among the leading causes of perinatal mortality and morbidity. It has been hypothesized that periodontal disease may cause PTB and/or LBW either …

Forming The Perception Of Wic Infant Feeding Recommendations: A Qualitative Study, Emily Fisher, Kathryn Wouk, Priyanka Patel, Chuanyi Tang, Qi Zhang

Community & Environmental Health Faculty Publications

Nearly half of newborns in the United States are enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC). Promoting breastfeeding is a programmatic priority, although formula vouchers are provided for those who do not exclusively breastfeed. Previous literature suggests that participant perception of WIC’s breastfeeding recommendations is a significant factor predicting breastfeeding initiation, duration, and exclusivity outcomes. However, little is known about how participants’ perceptions of WIC’s breastfeeding recommendations are formed. To address this knowledge gap, we conducted a qualitative pilot study in Nevada, interviewing 10 postpartum WIC mothers and 12 WIC staff who had interacted …

Maternal Occupation And Pediatric Brain Cancer In Kentucky, Mary Begley

Theses and Dissertations--Public Health (M.P.H. & Dr.P.H.)

Pediatric brain cancer is a rare and potentially deadly diagnosis that affects children in Kentucky at a higher incidence than those nationally. Limited exposures in children early in life to warrant the development and progression of brain cancer point to the role parental exposures experienced in the period prior to conception and throughout pregnancy may play in its development. Many of these exposures may be experienced through occupation. Data on a subset of pediatric brain cancer cases in Kentucky was compared to all cases diagnosed in the state from 1995 to 2019. Survey data of the study sample was collected …

Parental Instincts: The Neurological And Biological Factors Associated With Parenthood, Jared Reeder

Undergraduate Honors Theses

The following project involves a systematic review of the scientific literature on neural and biological changes of mothers and fathers in parenthood. Until very recently, little scientific research was devoted to studying how bearing children affects a man or woman’s long-term biology. Over the last twenty years, studies of neuroplastic changes in new mothers show specific neural mechanisms responsible for altering the behaviors of mothers during and after pregnancy. These changes in neuroplasticity alter behavior in such a way that led to mothers requiring less sleep and being more prone to hearing the cries of their children. In addition to …

Exposure To Pcb126 During The Nursing Period Reversibly Impacts Early-Life Glucose Tolerance, Brittany B. Rice, Keegan W. Sammons, Sara Y. Ngo Tenlep, Madeline T. Weltzer, Leryn J. Reynolds, Cetewayo S. Rashid, Hollie I. Swanson, Kevin J. Pearson

Human Movement Studies & Special Education Faculty Publications

Polychlorinated biphenyls (PCBs) are persistent environmental organic pollutants known to have detrimental health effects. Using a mouse model, we previously demonstrated that PCB126 exposure before and during pregnancy and throughout the perinatal period adversely affected offspring glucose tolerance and/or body composition profiles. The purpose of this study was to investigate the glucose tolerance and body composition of offspring born to dams exposed to PCB126 during the nursing period only. Female ICR mice were bred, and half of the dams were exposed to either vehicle (safflower oil) or 1 µmole PCB126 per kg of body weight via oral gavage on postnatal …

Medically Accurate Evidence-Based Sex Education And Abstinence-Only Sex Education: Impact On Teen Pregnancies In The United States, Nicole Chiu

Nursing | Senior Theses

The U.S. has funded abstinence-only programs to combat pregnancy rates for a long time. With numerous factors contributing to teen pregnancies, there have been a lot of ways that people have decided to try to decrease the number of teen pregnancies. For example, schools have either decided that they intend to fully educate their teenage students using medically accurate evidence-based sex education or come from a more conservative approach and give abstinence-only education. The objective of this investigation is to identify whether evidence-based sex education or abstinence-only sex education is more effective at combating teen pregnancy and abortion rates. This …

Abortion Decisions As Humanizing Acts: The Application Of Ambivalent Sexism And Objectification To Women-Centered Anti-Abortion Rhetoric, Rachel L. Dyer, Olivia R. Checkalski, Sarah Gervais

Department of Psychology: Faculty Publications

Women-centered anti-abortion rhetoric, grounded in ostensibly positive beliefs that pregnant people are precious objects who must be protected from having abortions, has proliferated anti-abortion activism and legislation. However, abortion stigma, marked by negative perceptions of people who terminate pregnancies, is the most widely used theoretical tool for understanding the social and psychological implications of abortion. In this article, we first integrate these two seemingly contradictory perspectives on abortion through the lens of ambivalent sexism theory. We then argue that ambivalent sexism paves the way for objectifying perceptions and treatment of pregnant people; specifically, our typology of reproductive objectification provides a …

Effect Of Positive Emotion Intervention During Late Pregnancy On Improving Colostrum Secretion: A Randomised Control Trial Protocol, Kechen Xu, Ying Xie, Xiujun Han, Ying Yu, Suqing Liu, Suliu Wu, Qian Yang, Qi Zhang

Community & Environmental Health Faculty Publications

Introduction Though evidence has revealed the beneficial effects of cognitive improvement interventions on breastfeeding, the effect of psychological interventions has rarely been studied. This study aims to test whether promoting a positive emotion intervention, 'Three Good Things' intervention, during the last trimester of pregnancy can enhance early colostrum secretion and breastfeeding behaviours by modulating the hormones associated with lactation (prolactin and insulin-like growth factor I). We will attempt to promote exclusive breastfeeding by using physiological behavioural measures.

Methods and analysis This study is designed as a randomised controlled trial conducted in the Women's Hospital School of Medicine at Zhejiang University …

Comparison Of Midwifery And Obstetric Care Among American Indian And Alaska Native Birthing People, Trista Barnhart

All Master's Theses

Despite making up only 3% of the U.S. population, American Indian/Alaska Native (AI/AN) individuals have the second highest maternal mortality rate in the United States, and the leading cause of maternal mortality and morbidity among AI/AN is postpartum hemorrhage. Many interventions used during childbirth have been identified as common causes of hemorrhage, such as lacerations of the vagina and cervix, operative vaginal deliveries, & augmentation of labor. Research has found that individuals who had midwives as their care providers have been found to be less likely to experience instrumental deliveries, epidural analgesia, labor augmentation, episiotomy or perineal lacerations, cesarean sections, …
