Perspective: The Evolution Of Hormones And Person Perception-A Quantitative Genetic Framework, Christopher I Gurguis, Tyler S Kimm, Teresa A Pigott Jan 2024

Perspective: The Evolution Of Hormones And Person Perception-A Quantitative Genetic Framework, Christopher I Gurguis, Tyler S Kimm, Teresa A Pigott

Faculty, Staff and Student Publications

Evolutionary biology provides a unifying theory for testing hypotheses about the relationship between hormones and person perception. Person perception usually receives attention from the perspective of sexual selection. However, because person perception is one trait in a suite regulated by hormones, univariate approaches are insufficient. In this Perspectives article, quantitative genetics is presented as an important but underutilized framework for testing evolutionary hypotheses within this literature. We note tacit assumptions within the current literature on psychiatric genetics, which imperil the interpretation of findings thus far. As regulators of a diverse manifold of traits, hormones mediate tradeoffs among an array of …


Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker Jan 2024

Examining Stigma In Rural Mental Health Care Settings: A Mixed Methods Approach, Lainie Krumenacker

Murray State Theses and Dissertations

More than half of Americans will be diagnosed with a mental illness in their lifetime (CDC, 2021), yet stigma towards mental health affects both patients and providers. Although programs exist to address stigma, improve cultural competency among providers, and educate families on the importance of support, facilities are often limited on programs they provide due to allocation of resources and funds. Without a shift in treatment and programing, stigma will continue to impact patient care and outcome.

This study explored stigma among mental health providers in rural communities, while exploring potential differences in treatment among patients due to race. Mental …


Cigarette Smoking Behaviors And Nicotine Dependence At The Intersection Of Sexual Identity And Sex In The United States: Findings From The National Survey On Drug Use And Health, Ollie Ganz, Jonathan A. Schulz, Sarah J. Ehlke, Jessica L. King Jensen, Andrea C. Villanti Jan 2024

Cigarette Smoking Behaviors And Nicotine Dependence At The Intersection Of Sexual Identity And Sex In The United States: Findings From The National Survey On Drug Use And Health, Ollie Ganz, Jonathan A. Schulz, Sarah J. Ehlke, Jessica L. King Jensen, Andrea C. Villanti

Psychology Faculty Publications

Introduction: Cigarette smoking is disproportionately high among lesbian, gay, and bisexual (LGB) adults. Yet, collapsing these identities into a monolith can disguise important within group disparities (e.g., lesbian/gay versus bisexual female). The purpose of this study is to report recent national prevalence estimates and trends of cigarette smoking behaviors and nicotine dependence by sexual identity and sex. Methods: Data were from the 2015–2019 National Survey on Drug Use and Health (n = 210,392; adults 18+), a nationally representative, repeated cross-sectional study of substance use and mental health in the U.S. We examined bivariate and multivariable associations between sexual identity and …


Facilitating Thought Progression To Reduce Depressive Symptoms: Randomized Controlled Trial, Shai-Lee Yatziv, Paola Pedrelli, Shira Baror, Sydney Ann Decaro, Noam Shachar, Bar Sofer, Sunday Hull, Joshua Curtiss, Moshe Bar Jan 2024

Facilitating Thought Progression To Reduce Depressive Symptoms: Randomized Controlled Trial, Shai-Lee Yatziv, Paola Pedrelli, Shira Baror, Sydney Ann Decaro, Noam Shachar, Bar Sofer, Sunday Hull, Joshua Curtiss, Moshe Bar

Psychology Faculty Publications

Background:

The constant rise in the prevalence of major depressive disorder calls for new, effective, and accessible interventions that can rapidly and effectively reach a wide range of audiences. Recent developments in the digital health domain suggest that dedicated online platforms may potentially address this gap. Focusing on targeting ruminative thought, a major symptomatic hallmark of depression, in this study we hypothesized that delivering a digital health-based intervention designed to systematically facilitate thought progression would substantially alleviate depression.

Objective:

The study aims to investigate the efficacy of a novel digital intervention on the reduction of depressive symptoms. This intervention was …


Assessment Of Simultaneous Alcohol And Cannabis Use And Its Related Consequences And Cognitions In College Students: A Narrative Review, Jennifer L. Shipley, Abby L. Braitman Jan 2024

Assessment Of Simultaneous Alcohol And Cannabis Use And Its Related Consequences And Cognitions In College Students: A Narrative Review, Jennifer L. Shipley, Abby L. Braitman

Psychology Faculty Publications

As rates of students using cannabis continue to rise, simultaneous use of alcohol and cannabis (such that their effects overlap; commonly referred to as simultaneous alcohol and marijuana [SAM] use) is prevalent among college students who use both substances. Although research focusing on SAM use and related cognitions and consequences continues to grow, there are no common established measures, as approaches vary across studies. This narrative review identifies current methods for assessing SAM use and measures of SAM-related consequences and cognitions (motives and expectancies) among college students, evaluates how they were developed, identifies gaps in the literature, and provides recommendations …


Mental Workload Modulates The Effects Of Baroreceptor Afferents On Sensorimotor Processing, Xiao Yang, Katie Herberlein, Anthony Reid, Dongfang Jiao, Fang Fang Jan 2024

Mental Workload Modulates The Effects Of Baroreceptor Afferents On Sensorimotor Processing, Xiao Yang, Katie Herberlein, Anthony Reid, Dongfang Jiao, Fang Fang

Psychology Faculty Publications

The heart–brain interaction is the main mechanism for maintaining normative physiological processes, and its dysregulation underlies the somatic symptoms of various mental disorders. Cortical inhibition, triggered by afferent signals from baroreceptor activation, induces systematic variations in sensorimotor responses within a cardiac cycle, with reaction times (RTs) slower at cardiac systole compared to diastole (known as cardiac cycle time effects). However, recent data suggest that baroreceptor afferents not only inhibit simple responses but also facilitate complex sensorimotor responses during cardiac systole. The mental workload that is implicated in complex responses may modulate the cardiac cycle time effects. The current study aimed …

The Minnesota Longitudinal Study of Risk and Adaptation (MLSRA) is a landmark prospective, longitudinal study of human development focused on a sample of mothers experiencing poverty and their firstborn children. Although the MLSRA pioneered a number of important topics in the area of social and emotional development, it began with the more specific goal of examining the antecedents of child maltreatment. From that foundation and for more than 40 years, the study has produced a significant body of research on the origins, sequelae, and measurement of childhood abuse and neglect. The principal objectives of this report are to document the …


Short-Term Blood Pressure Variability Among Young Adults At High Or Low Risk For Depression, Balázs Bence Nyárády, Miklós Vértes, Edit Dósa, Xiao Yang, Charles J. George, Enikõ Kiss, Iidiko Baji, Krisztina Kapornai, Maria Kovacs Jan 2024

Short-Term Blood Pressure Variability Among Young Adults At High Or Low Risk For Depression, Balázs Bence Nyárády, Miklós Vértes, Edit Dósa, Xiao Yang, Charles J. George, Enikõ Kiss, Iidiko Baji, Krisztina Kapornai, Maria Kovacs

Psychology Faculty Publications

Background: Depression has been shown to have adverse effects on blood pressure (BP) and is associated with high blood pressure variability (BPV). In turn, high short-term BPV has been related to eventual cardiovascular risk. But it is not clear how early in adulthood the detrimental effects of depression on BPV may be discerned, if being at high risk for depression also compromises BPV, and whether the clinical features of depression moderate its adverse effects. We investigated these three issues among young adults using an office-like setting. Methods: In total, 218 subjects with a history of childhood-onset major depressive episodes (probands), …


Neuroticism Mediates The Association Between Autistic Traits And Choice Reaction Time Among Young Adults, Kassandra De Jesus Cintron, Xiao Yang Jan 2024

Neuroticism Mediates The Association Between Autistic Traits And Choice Reaction Time Among Young Adults, Kassandra De Jesus Cintron, Xiao Yang

Psychology Faculty Publications

Autism spectrum disorder (ASD) is a neurodevelopmental disorder that influences an individual’s cognitive functions and social interaction. While most studies have focused on children and adolescents diagnosed with ASD, elevated levels of autistic traits in subclinical populations may also influence individuals’ daily functioning. Autistic traits are also linked to the Big Five personality. In particular, neuroticism (emotion instability) has been shown to be positively associated with autistic traits, which may contribute to behavioral symptoms of autistic traits. The present study aimed to investigate the association between autistic symptoms and sensorimotor processing among a subclinical population. One hundred young adults (M …


A Validation Study Of The Occupational Depression Inventory In Poland And Ukraine, Krystyna Golonka, Karine O. Malysheva, Dominika Fortuna, Bożena Gulla, Serhii Lytvyn, Leon T. De Beer, Irvin Sam Schonfeld, Renzo Bianchi Jan 2024

A Validation Study Of The Occupational Depression Inventory In Poland And Ukraine, Krystyna Golonka, Karine O. Malysheva, Dominika Fortuna, Bożena Gulla, Serhii Lytvyn, Leon T. De Beer, Irvin Sam Schonfeld, Renzo Bianchi

Publications and Research

This study examined the psychometric and structural properties of the Polish and Ukrainian versions of the Occupational Depression Inventory (ODI). We relied on two samples of Polish employees (NSample1 = 526, 47% female; NSample2 = 164, 64% female) and one sample of Ukrainian employees (NSample3 = 372, 73% female). In all samples, the ODI exhibited essential unidimensionality and high total-score reliability (e.g., McDonald’s omegas > 0.90). The homogeneity of the scale was strong (e.g., 0.59 ≤ scale-level Hs ≤ 0.68). The ODI’s total scores thus accurately ranked individuals on a latent occupational depression continuum. We found evidence of complete measurement invariance …


How The Lockdown Of Covid-19 Influenced The Neurocognitive And Psychosocial Development Of Preschoolers, Kay Picson Jan 2024

How The Lockdown Of Covid-19 Influenced The Neurocognitive And Psychosocial Development Of Preschoolers, Kay Picson

Nursing | Senior Theses

COVID-19 caused schools to turn to online learning through platforms such as Zoom or Google Meet. The influence and effects caused by the transition to online lessons and quarantine were seen across all patient populations and demographics, but none more so than preschool children, who are regarded as one of the more vulnerable populations due to their susceptibility to change. This research aims to fill gaps in the existing literature by evaluating the similarities and differences of the neurocognitive and psychosocial development of preschoolers exposed to the pandemic and those who were not. This study involves a comparative cohort approach …


Guideline For Creating A Support Group For Adults With Down Syndrome Who Suffer With Prolonged Grief, Brandon Chace Warman Jan 2024

Guideline For Creating A Support Group For Adults With Down Syndrome Who Suffer With Prolonged Grief, Brandon Chace Warman

Doctor of Nursing Practice (DNP) Scholarly Projects - Archive

Adults with Down syndrome process and express their grief differently from the general population. There are a multitude of support groups and organizations for individuals grieving a loss and experiencing prolonged grief but there are none that exist for people with Down syndrome. This project develops a guideline for creating support groups aimed at adults with Down syndrome who experience prolonged grief. Fifty-one pieces of literature from all over the world were reviewed to formulate recommendations that were graded by seven stakeholders. These recommendations were then used to develop a guideline for creating support groups for this population. Analysis of …


The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami Jan 2024

The Unequal Distribution Of Social Risk For Black Men Across The Life-Span. A Novel Framework., Waleed Y. Sami

Adultspan Journal

This conceptual overview offers a comprehensive overview of systemic pathways that negatively impact the mental health of Black Men throughout their lives. Our argument highlights the importance for counselors and mental health professionals to utilize a thorough social risk assessment that considers these pathways in order to effectively address the mental health needs of Black Men while fostering positive working relationships. This overview strongly advocates for the use of context and structural determinants when evaluating mental health symptoms. Without an appropriate understanding of social risk and determinants, counselors may inadvertently perpetuate disparities by decontextualizing symptomology, and reproducing racist discourse.

I Am Not A Hero: Heroic Action Divorces The Hero From The Political Community, Ari Kohen, Brian Riches, Andre Sólo Jan 2024

I Am Not A Hero: Heroic Action Divorces The Hero From The Political Community, Ari Kohen, Brian Riches, Andre Sólo

Department of Political Science: Faculty Publications

Most people who perform a heroic act will, afterward, deny that their actions were heroic and claim that anyone would have done the same, even though that is demonstrably false (and, often, others were present who failed to act heroically at all). The literature on the psychology of heroism has never investigated why this is. This theoretical paper proposes an answer and seeks to provoke exploration of a previously unexplored topic. We note that people who undertake heroic action face a unique conflict: they embody their community’s highest values, while simultaneously breaking norms to stand apart from that community. We …


Co-Occurrence Of Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder With Idiopathic Hypersomnia: Data From The Hypersomnia Foundation Registry, Sophie Sevan Mikkelsen Jan 2024

Co-Occurrence Of Autism Spectrum Disorder And Attention-Deficit/Hyperactivity Disorder With Idiopathic Hypersomnia: Data From The Hypersomnia Foundation Registry, Sophie Sevan Mikkelsen

Honors Undergraduate Theses

In recent years, hypersomnia patients and researchers alike have increasingly discussed the possibility of heightened comorbidities, or co-occurrences, of autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) with the central disorders of hypersomnolence: idiopathic hypersomnia (IH) and narcolepsy (N). While a few scarce studies have investigated a link between ADHD and N, there has been no research on the co-occurrence of these conditions with IH. This study, using data from the Hypersomnia Foundation’s CoRDS Patient Registry, is the first to identify self-reported rates of ASD and ADHD diagnoses by people with idiopathic hypersomnia. Four chi-square tests were conducted to determine …


Individual And Organizational Challenges To Implementing Prolonged Exposure Therapy In The Military Health System: A Systematic Review Of Client And Provider Perspectives, Paris R. Cloutier Jan 2024

Individual And Organizational Challenges To Implementing Prolonged Exposure Therapy In The Military Health System: A Systematic Review Of Client And Provider Perspectives, Paris R. Cloutier

Honors Undergraduate Theses

Military veterans and active-duty service members face high rates of posttraumatic stress disorder (PTSD), a chronic and debilitating condition that is comorbid with other negative psychological and social outcomes. PTSD symptomology in military careers is attributed to unique organizational factors and risks both during and post-deployment. Delivering modern, effective PTSD treatments derived from evidence-based research to the military population is a multi-faceted effort. Among these interventions, prolonged exposure therapy (PE) is a safe and effective trauma-focused treatment for veterans. To yield higher rates of PE success, common challenges faced by both military clients and their clinicians that may be impairing …


Does Heightened Perceptual Encoding In Blind Individuals Extend To Word Learning?, Lindsay N. Harris, Marissa Renee Bamberger Jan 2024

Does Heightened Perceptual Encoding In Blind Individuals Extend To Word Learning?, Lindsay N. Harris, Marissa Renee Bamberger

CISLL Publications

Past research reported blind participants tend to encode sensory details of encounters with stimuli they will later recall or recollect, whereas sighted individuals tend to abstract meaning from sensory information when encoding memories. Here we ask whether blind individuals’ use of perceptual in addition to semantic encoding extends to a task—word learning—whose purpose amounts to semantically encoding the word and definition. After studying the definitions of spoken or written words, blind braille readers (n = 23) and sighted print readers (n = 20) re-encountered each word and indicated whether it was previously presented in the same modality. Analyses …


An Examination Of Working Memory In Dancers And Non-Dancers, Mason Low Jan 2024

An Examination Of Working Memory In Dancers And Non-Dancers, Mason Low

All Master's Theses

The present study examined the behavioral working memory differences between dancers and non-dancers. Previous research has indicated that dance can provide an enhancing effect on working memory, particularly in non-dancers. A Dance History Questionnaire along with the letters backward, digits backward, digits forward, letters forward, and abstract visual subtests of the Test of Learning and Memory II was used to collect data. The current study found that dancers had greater visuospatial memory than non-dancers and that dance experience may have an effect on certain working memory tests such as the letters forward subtest.


A Domain-Agnostic Neurosymbolic Approach For Big Social Data Analysis: Evaluating Mental Health Sentiment On Social Media During Covid-19, Vedant Khandelwal, Manas Gaur, Ugur Kursuncu, Valerie L. Shalin, Amit P. Sheth Jan 2024

A Domain-Agnostic Neurosymbolic Approach For Big Social Data Analysis: Evaluating Mental Health Sentiment On Social Media During Covid-19, Vedant Khandelwal, Manas Gaur, Ugur Kursuncu, Valerie L. Shalin, Amit P. Sheth

Psychology Faculty Publications

Monitoring public sentiment via social media is potentially helpful during health crises such as the COVID-19 pandemic. However, traditional frequency-based, data-driven neural network-based approaches can miss newly relevant content due to the evolving nature of language in a dynamically evolving environment. Human-curated symbolic knowledge sources, such as lexicons for standard language and slang terms, can potentially elevate social media signals in evolving language. We introduce a neurosymbolic method that integrates neural networks with symbolic knowledge sources, enhancing the detection and interpretation of mental health-related tweets relevant to COVID-19. Our method was evaluated using a corpus of large datasets (approximately 12 …


The Relationship Between Moral Thought-Action Fusion And Scrupulosity Across Judaism, Christianity, And Islam, Kelsey Evey Jan 2024

The Relationship Between Moral Thought-Action Fusion And Scrupulosity Across Judaism, Christianity, And Islam, Kelsey Evey

Graduate Theses, Dissertations, and Problem Reports (ETD)

Scrupulosity is a subtype of obsessive-compulsive disorder (OCD) where individuals are upset by intrusive thoughts related to religious or moral issues. Current research suggests that scrupulosity occurs across the major world religions—including the Abrahamic religions (i.e., Judaism, Christianity, and Islam). Some research suggests that moral thought-action fusion (moral TAF), a dysfunctional belief that thinking something is equal to doing it, may only be pathological under certain circumstances (e.g., if it is not culturally normative). If this is true, the current cognitive model of scrupulosity may need to be amended to reflect how cultural differences impact the role of moral TAF …


Self-Efficacy And Parental Miscarried Helping In Adherence And Transition Readiness Among Adolescents And Young Adults With Epilepsy, Kirby-Estar G. Laguerre Jan 2024

Self-Efficacy And Parental Miscarried Helping In Adherence And Transition Readiness Among Adolescents And Young Adults With Epilepsy, Kirby-Estar G. Laguerre

Graduate Theses, Dissertations, and Problem Reports (ETD)

Background: Given the complex regimen associated with epilepsy, ensuring that adolescents and young adults (AYAs) adhere to their medications, and are ready to transition from pediatric to adult care, is crucial to optimizing their health outcomes. Several social and ecological factors such as self-efficacy and parental miscarried helping can strengthen or weaken an adolescent’s medication adherence and readiness to shift from pediatric to adult care. Intending to contribute to informing and improving clinical care, this study sought to understand the relationships between self-efficacy, parental miscarried helping, medication adherence, and transition readiness. Methods: Using a cross-sectional observational design, 46 AYAs with …


The Menstrual Cycle In Psychotherapy: Interventions, Therapist Engagement, And Blind Spots, Rozita Alaluf Jan 2024

The Menstrual Cycle In Psychotherapy: Interventions, Therapist Engagement, And Blind Spots, Rozita Alaluf

Dissertations and Theses

There is a dearth of literature on psychotherapy and menstruation, except for the treatment and diagnosis of issues associated with premenstrual distress. This study aimed to bridge this gap by investigating the frequency and context of discussions about the menstrual cycle, the factors influencing therapists’ engagement with this topic, and the therapeutic approaches utilized to address the menstrual cycle within psychotherapy.

In phase 1, 118 psychotherapists from various theoretical backgrounds completed a survey on menstruation in clinical practice. The data was analyzed using descriptive statistics. In phase 2, semi-structured interviews were conducted with 7 psychotherapists, primarily identifying their theoretical orientation …


Identifying Patterns For Neurological Disabilities By Integrating Discrete Wavelet Transform And Visualization, Soo Yeon Ji, Sampath Jayarathna, Anne M. Perrotti, Katrina Kardiasmenos, Dong Hyun Jeong Jan 2024

Identifying Patterns For Neurological Disabilities By Integrating Discrete Wavelet Transform And Visualization, Soo Yeon Ji, Sampath Jayarathna, Anne M. Perrotti, Katrina Kardiasmenos, Dong Hyun Jeong

Computer Science Faculty Publications

Neurological disabilities cause diverse health and mental challenges, impacting quality of life and imposing financial burdens on both the individuals diagnosed with these conditions and their caregivers. Abnormal brain activity, stemming from malfunctions in the human nervous system, characterizes neurological disorders. Therefore, the early identification of these abnormalities is crucial for devising suitable treatments and interventions aimed at promoting and sustaining quality of life. Electroencephalogram (EEG), a non-invasive method for monitoring brain activity, is frequently employed to detect abnormal brain activity in neurological and mental disorders. This study introduces an approach that extends the understanding and identification of neurological disabilities …


Giving People The Words To Say No Leads Them To Feel Freer To Say Yes, Rachel Schlund, Roseanna Sommers, Vanessa K. Bohns Jan 2024

Giving People The Words To Say No Leads Them To Feel Freer To Say Yes, Rachel Schlund, Roseanna Sommers, Vanessa K. Bohns

Articles

We examine how to structure requests to help people feel they can say no (or yes) more voluntarily. Specifically, we examine the effect of having the requester provide the request-target with an explicit phrase they can use to decline requests. Part of the difficulty of saying no is finding the words to do so when put on the spot. Providing individuals with an explicit script they can use to decline a request may help override implicit scripts and norms of politeness that generally dictate compliance. This should make individuals feel more comfortable refusing requests and make agreement feel more voluntary. …


Synthetic Neuroactive Steroids Targeting Gaba-A Receptors As A Potential Therapy For Contraceptive-Associated Mood Disorders, Alexandria A. Davis Jan 2024

Synthetic Neuroactive Steroids Targeting Gaba-A Receptors As A Potential Therapy For Contraceptive-Associated Mood Disorders, Alexandria A. Davis

Scripps Senior Theses

4-10% of women who use hormonal oral contraceptives (HOCs) discontinue use after experiencing symptoms of anxiety, irritability, and depression in the first 3 months of administration. Previous studies have acknowledged a relationship between HOCs and emotional dysregulation but have not identified mechanisms by which HOCs have this effect. As a result, effective treatment options for HOC-induced mood disorders are lacking. Current theories implicate combined-HOCs, particularly those containing ethinyl estradiol and levonorgestrel (EE-LNG), in reducing neuroactive steroid levels. Specifically, HOC users show decreases in allopregnanolone, a positive allosteric modulator associated with neuronal inhibition and emotional regulation. The objective of this study …


Extracellular Free Water As An Imaging Biomarker Of Neuroinflammation, Cristina N. Pinheiro Jan 2024

Extracellular Free Water As An Imaging Biomarker Of Neuroinflammation, Cristina N. Pinheiro

Theses and Dissertations--Psychology

Older adults experience a chronic state of heightened immune response referred to as “inflammaging” which can be observed by detecting levels of proinflammatory cytokines in blood serum. These proinflammatory cytokines are secreted in the central nervous system and may also enter the brain through the blood brain barrier. Previous literature has suggested that extracellular free water, a magnetic resonance imaging metric, may allow us to detect alterations in the extracellular space which are thought to correlate with inflammation in the central nervous system. This study examined the correlation between two proinflammatory cytokines, IL-6 and TNFα, collected longitudinally and cross-sectionally imaged …


Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg Jan 2024

Establishing The Feasibility Of Crowdsourcing To Study Value-Based Decision-Making In Substance Use Disorders, Thomas Shellenberg

Theses and Dissertations--Psychology

Substance use disorders (SUDs) are characterized by repeated choices to use drugs despite adverse consequences. Value-based decision-making theory posits that choices are guided by predicted values of available options which are updated based on outcomes. Computational modeling of reinforcement learning (RL) during choice tasks has shown promise for uncovering latent mechanisms of decision-making. Recruiting people with SUD is difficult, but crowdsourcing offers an alternative for accelerating data collection. However, the validity of computational modeling using online choice task data has not been well-established. This thesis aimed to use the online crowdsourcing platform Prolific to 1) compare online and in-person choice …

Electrophysiological And Clinical Fundamentals Of Qtc Prolongation Induced By Antipsychotic Medications, Zaid Naseer, Minaal Khan, Najeeb Manalai, Allison Foroobar, Patricia Harrison, Charles Scercy, Beth Yanoff, Partam Manalai

Department Surgery Faculty Publications

Patients with psychiatric disorders undergoing antipsychotic treatment are at an elevated risk for adverse cardiovascular events, including arrhythmias and sudden cardiac death. While the precise mechanisms linking cardiovascular diseases and psychiatric conditions remain unclear, QTc prolongation is suspected to be a contributing factor. The human ether-à-go-go-related gene (hERG, or KCNH2), which affects potassium channels, is implicated in the cardiotoxicity of various medications, including antipsychotics. This gene plays a critical role in determining whether a drug will be approved for market use. This paper elucidates the electrophysiological basis of QTc prolongation and reviews the evidence concerning which antipsychotics may exacerbate QTc …

Examining Predictors Of Cocaine Withdrawal Syndrome At The End Of Detoxification Treatment In Women With Cocaine Use Disorder, Bernardo Aguzzoli Heberle, Bruno Kluwe-Schiavon, Carla Bicca, Leonardo Melo Rothmann, Rodrigo Grassi-Oliveira, Thiago Wendt Viola

Faculty, Staff and Student Publications

BACKGROUND: Detoxification is frequently recommended as a treatment for moderate to severe Cocaine Use Disorder (CUD). However, the response to detoxification varies among patients, and previous studies have focused mostly on patterns of drug use behavior to test associations with treatment outcomes, overlooking the potential impact of psychosocial factors, other clinical variables, and individual life experiences. In this study we comprehensively examined several variables aiming to find the most relevant predictors to classify patients with severe versus non-severe cocaine withdrawal symptoms at the end of detoxification.

METHODS: Data from 284 women with CUD who enrolled in a 3-week detoxification program …
