Probe Into Mental Health Issues Caused By Major Natural Disasters And Crisis Interventions, Yankun Sun, Yimiao Gong, Xuebing Huang, Ying Qian, Siwei Sun, Hongguang Chen, Lin Lu Nov 2023

Probe Into Mental Health Issues Caused By Major Natural Disasters And Crisis Interventions, Yankun Sun, Yimiao Gong, Xuebing Huang, Ying Qian, Siwei Sun, Hongguang Chen, Lin Lu

Bulletin of Chinese Academy of Sciences (Chinese Version)

Major natural disasters not only cause severe personnel casualties and social losses, but also bring long-lasting mental health issues related to psychological trauma. Timely and efficient post-disaster crisis interventions can avoid indelible psychological damages that disasters bring to populations such as survivors, victims’ families, witnesses, and rescuers. This article overviews the impact of major natural disasters on mental health and the characteristics of post-disaster psychological crisis. It also summarizes previous experience in post-disaster crisis interventions. In addition, it probes into future post-disaster crisis interventions, including improvement of the legal system for crisis intervention, clarification of the role of the government …

BACKGROUND: Child abuse and neglect (CAN) is prevalent, associated with long-term adversities, and often undetected. Primary care settings offer a unique opportunity to identify CAN and facilitate referrals, when warranted. Electronic health records (EHR) contain extensive information to support healthcare decisions, yet time constraints preclude most providers from thorough EHR reviews that could indicate CAN. Strategies that summarize EHR data to identify CAN and convey this to providers has potential to mitigate CAN-related sequelae. This study used expert review/consensus and Natural Language Processing (NLP) to develop and test a lexicon to characterize children who have experienced or are at risk …


Taking Songs To Heart: An Investigation Into Musical Appreciation, Anna Kate Lockhart, Eric A. Febles, Valeria Draine, Kaitlin Pendasulo Nov 2023

Taking Songs To Heart: An Investigation Into Musical Appreciation, Anna Kate Lockhart, Eric A. Febles, Valeria Draine, Kaitlin Pendasulo

Science University Research Symposium (SURS)

Abstract

Music cross-culturally occupies a central part of day-to-day living (Trehub et al., 2015). Research has demonstrated music’s consistent ability to modulate emotional states, through the investigation of properties like tempo and key (Res, 2011; Bella, 2001; Jongwan,, 2018; Schellenberg, 2010). Heartbeat is a steady rhythm that each human alive and well experiences daily, and heart rate, specifically the resting heart rate, has been suggested to set a baseline rhythm that may influence perception of musical valence (Koelsch & Jancke, 2015). The current study aims to investigate this hypothesis by establishing a resting heart rate level and modulating the speed …

Charting And Checking For Suicidality In A Family Medicine Residency Clinic, Bridget Murphy, Stacy Ogbeide

Journal of Human Services Scholarship and Interprofessional Collaboration

Suicide is a leading cause of death in the United States, and many individuals who die by suicide are likely to have seen a primary care physician (PCP) within the month of their death. Thus, the goal of this quality improvement (QI) project was to examine suicidality documentation practices of interprofessional clinicians within a Family Medicine residency clinic, thus providing rationale for continued research and a template for other clinics to emulate. The QI project used the Plan-Do-Study-Act cycle to survey 28 Family Medicine residents, faculty, and trainees for the Plan stage of the cycle in 2022 and assessed their …

Treatment-resistant depression (TRD) is a term used to describe a particular type of major depressive disorder (MDD). There is no consensus about what defines TRD, with various studies describing between 1 and 4 failures of antidepressant therapies, with or without electroconvulsive therapy (ECT). That is why TRD is such a growing concern among clinicians and researchers, and it explains the necessity for investigating novel therapeutic targets beyond conventional monoamine pathways. An imbalance between two primary central nervous system (CNS) neurotransmitters, L-glutamate and γ-aminobutyric acid (GABA), has emerged as having a key role in the pathophysiology of TRD. In this …


Relation Between Fine And Gross Motor Skills And Observation Of Sociocultural Factors Across The First Year Of Infancy, Erika Garcia Mora Nov 2023

Relation Between Fine And Gross Motor Skills And Observation Of Sociocultural Factors Across The First Year Of Infancy, Erika Garcia Mora

LSU Doctoral Dissertations

The development of independent arms-free sitting, which frees an infant’s arms to explore objects in their environment (Soska & Adolph, 2014) is observed to propagate an increase in the frequency of manual and manipulatory actions (Marcinowski, et al., 2019; Mlincek, et. al., 2022). Active object exploration provides the infant with more sensory information of the fundamental characteristics of objects in their environment. Thus, this dissertation examined the quality and quantity of object exploration across seated postures.

Additionally, the literature claiming that infants raised in low-income households having fewer resources for effective development is being countered by considering a more holistic …


Examining The Evidence Base For Burnout, Renzo Bianchi, Irvin Schonfeld Nov 2023

Examining The Evidence Base For Burnout, Renzo Bianchi, Irvin Schonfeld

Publications and Research

Burnout has elicited growing interest among occupational health specialists in recent decades. Since 2019, the World Health Organization has characterized burnout as a syndrome resulting from chronic, unmanageable workplace stress. Accordingly, three symptoms define the entity: (i) feelings of energy depletion or exhaustion; (ii) increased mental distance from one’s job or feelings of negativism or cynicism towards one’s job; and (iii) a sense of ineffectiveness and lack of accomplishment. We call into question the definition of burnout embodied in the Maslach Burnout Inventory and incorporated into the ICD-11. We draw stakeholders’ attention to the fact that burnout’s symptoms and etiology …

Burnout has elicited growing interest among occupational health specialists in recent decades. Since 2019, the World Health Organization has characterized burnout as a syndrome resulting from chronic, unmanageable workplace stress. According to the ICD-11, three symptoms define the entity: feelings of exhaustion, increased mental distance from one’s job, and a sense of ineffectiveness at work, all of which correspond to the structure of the Maslach Burnout Inventory. The ICD-11 includes burnout among the factors that influence health status. This paper calls into question that conceptualization based on a number of lines of evidence. The evidence includes the following: burnout was …

A Preliminary Timeline Of The Midbrain Development In The Monodelphis Domestica Animal Model, Ismael Perez, John L. Vandeberg, Mario Gil Oct 2023

A Preliminary Timeline Of The Midbrain Development In The Monodelphis Domestica Animal Model, Ismael Perez, John L. Vandeberg, Mario Gil

Research Colloquium

Introduction: The Brazilian short-tailed opossum (Monodelphis Domestica) is an understudied animal model compared to the Mus musculus that has been identified as a perfect candidate to study neurodevelopment (Baggott, L. & Moore, H., 1990). What makes the Monodelphis Domestica a perfect specimen for neurodevelopment is that the embryo develops outside the pouch of the mother providing easy noninvasive access to track changes across different developmental stages (Mate et al., 1994).

Objective: The objective of the study is to compare the area and volume in the development of the Monodelphis’s midbrain across three different developmental stages. Our research is beneficial because …

School of Medicine Faculty Publications

Food insecurity is a national issue that disproportionately impacts Louisiana citizens, contributing to the state’s poor health outcomes. We know that the Supplemental Nutrition Assistance Program (SNAP) and food pantries improve access to food, but we have limited data on what interventions improve food insecurity. The Geaux Get Healthy Clinical Program at Our Lady of the Lake (GGHOLOL) is a clinic-based community program that leverages community partnerships and a clinical setting to provide education and access to resources for individuals with food insecurity. This prospective study examines the impact of GGHOLOL on food insecurity as a pre-post survey evaluation over …

Smokers with stronger neuroaffective responses to drug-related cues compared to non-drug-related pleasant images (C>P) are more vulnerable to compulsive smoking than individuals with the opposite brain reactivity profile (P>C). However, it is unknown if these neurobehavioral profiles exist in individuals abusing other drugs. We tested whether individuals with cocaine use disorder (CUD) show similar neuroaffective profiles to smokers. We also monitored eye movements to assess attentional bias toward cues and we further performed exploratory analyses on demographics, personality, and drug use between profiles. Participants with CUD (n=43) viewed pleasant, unpleasant, cocaine, and neutral images while we recorded electroencephalogram. …

Faculty, Staff and Students Publications

BACKGROUND: Misophonia is characterized by intense emotional reactions to specific sounds or visual stimuli and typically onsets during childhood. An obstacle for research and clinical practice is that no comprehensively evaluated measures for pediatric misophonia exist.

METHODS: In a sample of 102 youth meeting the proposed diagnostic criteria of misophonia, we evaluated the child and parent-proxy versions of the self-reported Misophonia Assessment Questionnaire (MAQ; assessing broad aspects of misophonia) and the child version of the Amsterdam Misophonia Scale (A-MISO-S; assessing misophonia severity). Confirmatory and exploratory factor analysis were used to examine factor structures of the measures. Further, child-parent agreement on …


Predictors And Moderators Of Treatment Outcomes For Anxious Children Randomized To Computer-Assisted Cognitive Behavioral Therapy Or Standard Community Care, Orri Smárason, Andrew G Guzick, Wayne K Goodman, Alison Salloum, Eric A Storch Oct 2023

Predictors And Moderators Of Treatment Outcomes For Anxious Children Randomized To Computer-Assisted Cognitive Behavioral Therapy Or Standard Community Care, Orri Smárason, Andrew G Guzick, Wayne K Goodman, Alison Salloum, Eric A Storch

Faculty, Staff and Students Publications

Introduction:

Computer-assisted cognitive behavioral therapy (CCBT) for childhood anxiety disorders may aid the dissemination of CBT, while maintaining treatment fidelity. Although CCBT is an effective intervention, not everyone benefits equally from treatment. Identifying patient characteristics that predict who will benefit from treatment and to what extent can help with matching patients to suitable interventions, and allow researchers and clinicians to modify, and individualize, their treatment formats more effectively. Such predictors and moderators have not yet been examined for CCBT outcomes in anxious children and studies of more traditional treatment formats have yielded inconsistent results.

Methods:

Using data from a randomized …

Mind, Body And Race: A Look Into How Implicit Biases Influence The Perception Of Emotion, Faiza Ahmad, Adam Anderson, James Dalton Rounds, Christina Chick, Alize Hill

Research Symposium

Background: Most research examining the effects of implicit race-based biases in emotion perception has focused on the perception of Black faces as being angry. Limited work has been done examining the perception of “approach” emotions such as fear. Furthermore, most studies have predominantly used White subjects. Our study examined the role of implicit racial biases in shaping the perception of both anger and fear in White, Black and Asian participants.

Methods: 78 participants completed a Go/NoGo task in which they were asked to categorize different race faces as portraying either anger or fear. Participants would be asked to press the …

Adverse Childhood Experiences And Resilience In Medical School Students: A Scope Of Medical Literature, Andrea Soto Abarca, Yvette Cortino, Juan Carlos Lopez Alvarenga, Maya Guevara

Research Symposium

Background: Adverse childhood experiences (ACEs) represent types of childhood trauma that are associated with long-term negative effects on health and wellbeing. An elevated number of ACEs can lead to depression, suicidality, alcoholism, and substance use. Factors that can protect a person from increased health risks include resilience, which is broadly defined as the ability to bounce back from adversity. Few studies have analyzed the exposure of ACEs in medical students, however, there is extensive literature on how low levels of resilience are linked to higher rates of depression, fatigue, and burnout among medical students. Little is known about the …

One Size Doesn’T Fit All: Attitudes Towards Work Modify The Relation Between Parental Leave Length And Postpartum Depression, Christine Y. Chang, Sabrina R. Liu, Laura M. Glynn

Psychology Faculty Articles and Research

The present study aimed to investigate the relationship between parental leave length and maternal depressive symptoms at six- and twelve-months postpartum and whether this relation was influenced by women’s attitudes towards leave, whether leave was paid or unpaid, and the reason they returned to work. The sample included 115 working women recruited during pregnancy as part of a larger longitudinal study. Analyses revealed that maternal attitudes toward leave influenced the association between leave length and depressive symptoms. Specifically, longer leaves were associated with increased depressive symptoms for women who missed their previous activities at work. Furthermore, women who missed work …

Decades of inquiry on intimate partner violence show consistent results: violence is woefully common and psychologically and economically costly. Policy to prevent and effectively intervene upon such violence hinges upon comprehensive understanding of this phenomenon at a population level. The current study prospectively estimates the cumulative incidence of sexual and physical dating violence (DV) victimization/perpetration over a 12-year timeframe (2010–2021) using diverse participants assessed annually from age 15 to 26. Data are from Waves 1–13 of an ongoing longitudinal study. Since 2010 (except for 2018 and 2019), participants were assessed on past-year physical and sexual DV victimization and perpetration. Participants …


Expressive Arts Therapy To Support Positive Experiences Of Embodiment Among Rural Lgbtq+ Adults: A Literature Review, Ann Stromgren Sep 2023

Expressive Arts Therapy To Support Positive Experiences Of Embodiment Among Rural Lgbtq+ Adults: A Literature Review, Ann Stromgren

Expressive Therapies Capstone Theses

This paper investigates the use of expressive arts therapy to support LGBTQ+ adult clients in rural communities. Caring professionals in rural areas often lack training on how to work with LGBTQ+ clients, and best practices for clinical mental health counseling with rural LGBTQ+ clients have yet to be defined. Some evidence suggests that using “metronormative” best practices with rural clients may be irrelevant or cause harm (Giano et al., 2020). Although some recommendations exist for using expressive therapies with LGBTQ+ clients, they are rarely evidence-based, as very few empirical studies exist evaluating the effectiveness of expressive therapy interventions with LGBTQ+ …

Making Mindfulness More Accessible: A Practical Guide To Trauma-Informed Mindfulness, Leslie Formby Sep 2023

Making Mindfulness More Accessible: A Practical Guide To Trauma-Informed Mindfulness, Leslie Formby

Mindfulness Studies Theses

Mindfulness is currently embedded in a growing understanding of how trauma permeates and adversely impacts peoples’ physical and psychological well-being. Increased awareness of the prevalence of trauma and its harmful effects has led to renewed interest in mindfulness to help manage the challenges generated by the detrimental effects of trauma.

These effects may draw people to mindfulness and, in turn, may make the benefits of mindfulness out of reach. Mindfulness methods and practice adaptations have been found to help trauma survivors experience the benefits of what the Buddha taught. As a support for those engaging in mindfulness and meditation, this …

Journal of Health Research

Background: Individual lifestyle risk factors have been linked to increased mortality globally; however, there is limited data on these associations in Russia. A secondary analysis of the Russia Longitudinal Monitoring Survey (RLMS) data was conducted to close this gap.

Methods: The secondary data have been obtained from a nationally-representative annual cohort survey conducted by the Higher School of Economics (HSE). In this original study, for the first time in Russia, we extracted RRs for researched risk factors. Of additional original value, we made a prospective-retrospective cohort based on a representative longitudinal survey and provided the deaths as outcomes for survival …


Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger Sep 2023

Theories Of Consciousness And A Life Worth Living, Liad Mudrik, Myrto Mylopoulos, Niccolo Negro, Aaron Schurger

Psychology Faculty Articles and Research

What is it that makes a life valuable? A popular view is that life’s moral worth depends in some way on its relationship to consciousness or subjective experience. But a practical application of this view requires the ability to test for consciousness, which is currently lacking. Here, we examine how theories of consciousness (ToCs) can help do so, focusing especially on difficult cases where the answer is not clear (e.g. fetuses, nonhuman animals, unresponsive brain-injured patients, and advanced artificial systems). We consider five major ToCs and what predictions they offer: Integrated information theory, Higher-Order Thought Theory, Recurrent Processing Theory, Global …

BACKGROUND AND HYPOTHESIS: Mounting evidence supports cerebrovascular contributions to schizophrenia spectrum disorder (SSD) but with unknown mechanisms. The blood-brain barrier (BBB) is at the nexus of neural-vascular exchanges, tasked with regulating cerebral homeostasis. BBB abnormalities in SSD, if any, are likely more subtle compared to typical neurological insults and imaging measures that assess large molecule BBB leakage in major neurological events may not be sensitive enough to directly examine BBB abnormalities in SSD.

STUDY DESIGN: We tested the hypothesis that neurovascular water exchange (Kw) measured by non-invasive diffusion-prepared arterial spin label MRI (n = 27 healthy controls [HC], n = …


Attenuated Typicality Effect In Category-Based Inferences: Implications For Autism Spectrum Disorder, Janani Rajagopalan Sep 2023

Attenuated Typicality Effect In Category-Based Inferences: Implications For Autism Spectrum Disorder, Janani Rajagopalan

Dissertations, Theses, and Capstone Projects

Individuals diagnosed with Autism Spectrum Disorder (ASD) often encounter challenges in assimilating atypical exemplars into their categorical prototypes, a cognitive hurdle that can impact their interpretative and integrative capacities. Addressing this problem, the present research sought to develop a robust methodological approach to reduce the effect of this disparity. We examined the elements embedded within the category's internal structure, with the intention of experimentally attenuating the pronounced typicality effect, which is often exaggerated in ASD.

Across four experiments, the thesis investigated the cognitive and neural underpinnings that shape the access to the typicality gradient intrinsic to a category's structure. The …

To Produce Or Not To Produce? Contrasting The Effect Of Substance Abuse In Social Decision-Making Situations, Laurent Avila-Chauvet, Diana Mejía Cruz, Óscar García-Leal, Bruno Kluwe-Schiavon

Faculty, Staff and Student Publications

Substance use disorders (SUD) have been related to high criminal justice costs, expensive healthcare, social impairment, and decision-making deficits. In non-social decision-making tasks, people with SUD tend to take more risks and choose small immediate rewards than controls. However, few studies have explored how people with SUD behave in social decision-making situations where the resources and profits depend directly on participants' real-time interaction, i.e., social foraging situations. To fulfill this gap, we developed a real-time interaction task to (a) compare the proportion of producers (individuals who tend to search for food sources) and scroungers (individuals who tend to steal or …

Inflammation and social behavior deficits are associated with a number of neuropsychiatric disorders. Chronic stress, a major risk factor for depression and other mental health conditions is known to increase inflammatory responses and social behavior impairments. Disturbances in mitochondria function have been found in chronic stress conditions, however the mechanisms that link mitochondrial dysfunction to stress-induced social behavior deficits are not well understood. In this study, we found that chronic restraint stress (RS) induces significant increases in serum cell-free mitochondrial DNA (cf-mtDNA) levels in mice, and systemic Deoxyribonuclease I (DNase I) treatment attenuated RS-induced social behavioral deficits. Our findings revealed …
