Intersect Between Brain Mechanisms Of Conditioned Threat, Active Avoidance, And Reward, Muhammad Badarnee, Zhenfu Wen, Mira Z Hammoud, Paul Glimcher, Christopher K Cain, Mohammed R Milad

Faculty, Staff and Student Publications

Active avoidance is a core behavior for human coping, and its excess is common across psychiatric diseases. The decision to actively avoid a threat is influenced by cost and reward. Yet, threat, avoidance, and reward have been studied in silos. We discuss behavioral and brain circuits of active avoidance and the interactions with fear and threat. In addition, we present a neural toggle switch model enabling fear-to-anxiety transition and approaching reward vs. avoiding harm decision. To fully comprehend how threat, active avoidance, and reward intersect, it is paramount to develop one shared experimental approach across phenomena and behaviors, which will …

Memorability Of Novel Words Correlates With Anterior Fusiform Activity During Reading, Oscar Woolnough, Nitin Tandon

Faculty, Staff and Student Publications

Our memory for the words we already know is best predicted by their associated meanings. However, the factors that influence whether we will remember a new word after we see it for the first time are unclear. We record memory performance for 2100 novel pseudowords across 1804 participants during a continuous recognition task. Participants show significant agreement across individuals for which novel words were memorable or forgettable, suggesting an intrinsic memorability for individual pseudowords. Pseudowords that are similar to low-frequency known words, with sparse orthographic neighbourhoods and rarely occurring letter pairs, are more memorable. Further, using intracranial recordings in 36 …

Recent studies have highlighted the crucial role of microglia (MG) and their interactions with the gut microbiome in post-stroke neuroinflammation. The activation of immunoregulatory pathways, including the aryl hydrocarbon receptor (AHR) pathway, is influenced by a dynamic balance of ligands derived from both the host and microbiota. This study aimed to investigate the association between stroke-induced dysbiosis and the resultant imbalance in AHR ligand sources (loss of microbiota-derived [indole-based] and increase of host-derived [kynurenine-based]) after stroke. Microbiota-derived AHR ligands decreased in human plasma and remained low for days following an ischemic stroke highlighting the translational significance. Transient-middle-cerebral-artery-occlusion was performed in …

Podcasting Towards Togetherness: Utilizing Podcasts To Improve Departmental Camaraderie And Well-Being, Michael Petrauskis, Colleen Gutman, Rosemarie Fernandez

Faculty, Staff and Students Publications

Background/Objectives: Lithium is the gold standard for treating Bipolar Disorder (BD), but its effectiveness varies widely. While clinical and environmental factors may influence response, it remains unclear if screening tools can reliably predict lithium response outcomes. This study explores this potential using two widely used screening instruments for BD.

Methods: A total of 146 patients with BD were evaluated. Lithium response was assessed using the Alda Scale, while hypomanic and manic symptoms were characterized through the Hypomania Checklist-32 (HCL-32) and the Mood Disorder Questionnaire (MDQ). Group differences in HCL-32 and MDQ scores were analyzed using ANOVA, and a multivariate model …

Epidemiological Characteristics Of Patients With Supraventricular Tachycardias Who Were Inappropriately Diagnosed With Panic Attacks: Experience From A Large Saudi Tertiary Care Center, Ghram Awlia, Ahmed T. Mokhtar, Maha Alsaiari, Nagham Alsolaimani, Waddah Ashram, Naeem Alshoaibi, Alaa Algazzar

Journal of the Saudi Heart Association

Objectives: Supraventricular tachycardia (SVT) is a significant cause of morbidity in patients visiting cardiology clinics with a chief complaint of palpitations and notable signs of distress worldwide. SVTs and panic attacks have overlapping clinical presentations, beginning with rapid palpitations of the heart that start abruptly and can be accompanied by shortness of breath, chest pain or discomfort, and a feeling of lightheadedness. The diagnosis could be straightforward if an ECG is recorded precisely during the attack. The chances of misdiagnosing patients with panic attacks increase because of the self-terminating nature of SVTs. Given the diagnostic dilemma caused by these conditions …

The Unfolding Story Of Protein Misfolding Causing Alzheimer Disease In Recipients Of Human Pituitary Growth Hormone, Evan G. Graber, Sayed M. Hadi Hosseini, Darrell M. Wilson, Alan D. Rogol

Division of Endocrinology, Diabetes and Metabolic Diseases Faculty Papers

Human growth hormone (hGH) has been in clinical use for children with GH deficiency (GHD) since the late 1950s. The original formulations were considered very safe with few adverse events reported. That changed remarkably in 1985 when the first patients with GHD, who had been treated with cadaveric hGH, were diagnosed with Creutzfeldt-Jakob disease (CJD). Fortunately, that same year a robust supply of recombinant hGH was released to the market whose adverse event profile did not include CJD. Patients who had received National Hormone and Pituitary Program hGH have been continuously followed since 1985. It is clear that prions are …

Multimodal Objective Assessment Of Impulsivity In Healthy And Mood Disorder Participants, Bishal Lamichhane, Nidal Moukaddam, Ramiro Salas, Wayne Goodman, Ashutosh Sabharwal

Faculty, Staff and Students Publications

Impulsivity represents an individual's tendency to act on urges without sufficient forethought. Heightened impulsivity is a hallmark of many mental health disorders. Objective impulsivity assessments could improve risk evaluation, diagnosis, and behavioral outcome monitoring in impulsivity-related health disorders. Towards objective impulsivity assessment, in this work, we identify impulsivity correlates in objective measurements, investigate their complementarity, and contrast impulsivity mechanisms across health conditions. We analyzed behavioral tests, heart rate variability (HRV), and fMRI-based brain connectivity in 227 healthy participants and 34 participants with mood disorders. Impulsivity dimensions had complementary correlates in objective measurements, with fMRI providing the strongest correlates. Multimodal assessment …

Navigating Epstein-Barr Virus (Ebv) And Post-Transplant Lymphoproliferative Disorder (Ptld) In Pediatric Liver Transplantation: Current Knowledge And Strategies For Treatment And Surveillance, Erin Y Chen, Natasha Dilwali, Krupa R Mysore, Sara Hassan, Sara Kathryn Smith, Wikrom Karnsakul

Faculty, Staff and Students Publications

Epstein-Barr virus (EBV) is strongly associated with the development of post-transplant lymphoproliferative disorder (PTLD) in pediatric liver transplant recipients. PTLD is one of the most common malignancies following liver transplantation and is associated with significant morbidity and mortality. Factors such as EBV-serostatus mismatch and prolonged or high levels of immunosuppression impact a patient's risk of developing PTLD. While pre-transplant EBV serological screening and post-transplant monitoring of EBV-DNA levels are strongly recommended, universal guidelines for its prevention and management are lacking. Due to a lack of robust prospective studies, current clinical practices vary widely. The treatment of PTLD typically involves reducing …

Novel Biomarkers Of Fetal And Neonatal Environmental Exposure, Effect And Susceptibility, Cynthia F. Bearer

Faculty Scholarship

Abstract: Rapid advancements in science and technology have allowed medical providers to treat wider ranges of diseases with safer and more effective therapies than ever before. One of the areas of health that has been consistently understudied, however, is one that affects us all: environmental health or the effects that the chemicals we are exposed to every day have on our acute and chronic health. This effect can be exacerbated during and shortly after pregnancy, as an individual exposure is often shared by both the mother and the fetus/neonate. The diagnosis and monitoring of chemical exposure can be quite challenging, …

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

Despite the existence of a highly effective and safe vaccine against human papillomavirus (HPV) infection, vaccination rates remain low. The most prevalent HPV-associated malignancy in the United States is oropharyngeal cancer, but otolaryngology practitioners do not offer the HPV vaccine, and their feelings around offering HPV vaccination have not been evaluated. A 43-question survey, including a twelve-question knowledge quiz, was sent to otolaryngology practitioners at seven academic institutions. Twelve questions comprised a knowledge quiz testing practitioner understanding of HPV, while the remainder of the questions evaluated comfort with and likelihood of recommending vaccination. Of the 442 practitioners who were sent …

Transcranial Magnetic Stimulation As A Treatment Modality For Functional Bowel Disorder And Irritable Bowel Syndrome And Possible Correlations With The Gut-Brain Axis: A Review, Lauren Draper, Devin Pfister, Ethan Zaugg

Annual Research Symposium

Functional Bowel Disorders (FBD), including Irritable Bowel Syndrome (IBS), are highly prevalent gastrointestinal conditions classified as Disorders of Gut-Brain Interactions (DGBIs) under the Rome IV criteria. These conditions, marked by abdominal pain, altered bowel habits, and significant psychological comorbidities, present substantial challenges in both diagnosis and treatment. Conventional therapies primarily target gut-centric mechanisms but often yield limited efficacy, underscoring the need for approaches that account for the complex interplay of the gut-brain axis in DGBI pathophysiology.

Pharmacy and Wellness Review

Pregnancy, a period of dynamic physiological changes, necessitates careful consideration of external influences on maternal and fetal health. Despite increasing legalization and prevalence, the impact of cannabis use during gestation remains a topic of significant concern and investigation.

Recent studies have shed light on the consequences of in utero cannabis exposure, encompassing both fetal and maternal outcomes. Notably, several studies have identified associations between cannabis exposure during pregnancy and adverse fetal outcomes, including small-for-gestational-age birth, altered neurodevelopment, preterm birth, and increased risk of neonatal morbidity. Evidence to date underscores the urgent need for education, intervention, and regulatory oversight regarding cannabis …

The current study applied a mixed methods approach to better understand attitudes about making lifestyle changes and current dietary and physical activity behaviors among cancer patients with MetS at a cancer center and to explore the suitability of brief lifestyle questionnaires to help providers understand their patients' lifestyle attitudes and habits. Qualitative interviews were used to obtain patients' perspectives about lifestyle changes, and 3 quantitative questionnaires-the Readiness Ruler, Rate Your Plate, and the International Physical Activity Questionnaire-Short Form (IPAQ-SF)-were used to measure patients' readiness for lifestyle change, …

A Compelling Case Of The Use Of Electroconvulsive Therapy In Severe Treatment Resistant Depression With Suicidality, Neha Narayanan, Ryan Tam, James Mead

Advances in Clinical Medical Research and Healthcare Delivery

Treatment-resistant depression is a condition that occurs when an individual, experiencing major depressive disorder episodes, has failed the first line of treatment with medication therapy of adequate dose and duration. This is important to be addressed as there is a high likelihood of progression to having thoughts and an intended plan for suicide. Electroconvulsive therapy is a recommended option for those who have failed medication therapy, but it has been controversial in its use due to its stigma and side effects of memory impairment. Here, we present a case of a patient who had undergone several sessions of ECT with …

Displaced: An Ethnography Of Language And Identity Loss, Ariel Caroline Wilsey-Gopp

Dissertations and Theses

Through ethnography and personal narrative, I explore the language and identity loss of one person, my father, in order to understand the complex issues surrounding the effects of symbolic and structural violence on language and identity development. Through personal narrative, fieldwork, and interviews, I tell the story of one person, born in wartime during Nazi occupied Serbia, and follow the guiding questions: how does language get lost and what are the effects? Drawing on methodology set forth by empirical ethnographical work as well as more recent theory around epigenetics and trauma, my research synthesizes into focus three pillars of understanding …

For most researchers, academic publishing serves two goals that are often misaligned-knowledge dissemination and establishing scientific credentials. While both goals can encourage research with significant depth and scope, the latter can also pressure scholars to maximize publication metrics. Commercial publishing companies have capitalized on the centrality of publishing to the scientific enterprises of knowledge dissemination and academic recognition to extract large profits from academia by leveraging unpaid services from reviewers, creating financial barriers to research dissemination, and imposing substantial fees for open access. We present a set of perspectives exploring alternative models for communicating and disseminating scientific research. Acknowledging that …

Evaluating Donor-Recipient Sex Mismatch In Anterior Cruciate Ligament Reconstruction With Allograft: Outcomes At 2 Years Postoperatively, Connor Crutchfield, Natalie Lowenstein, Chilan Leite, Christian Lattermann, Elizabeth Matzkin

SKMC Student Presentations and Publications

BACKGROUND: Female patients tend to suffer a greater risk of reinjury and worse patient-reported outcome measures (PROMs) after anterior cruciate ligament reconstruction (ACLR) than male patients, regardless of the graft type used.

PURPOSE/HYPOTHESIS: This study explored the role of donor-recipient sex mismatching to help explain these sex-based dispar- ities in outcomes after ACLR with an allograft. The hypothesis was that allograft donor-recipient sex mismatch would adversely affect surgical outcomes at a 2-year follow-up, with male-to-female graft donations yielding the lowest rates of success.

STUDY DESIGN: Cohort study; Level of evidence, 3.

METHODS: Patients who underwent primary ACLR with an allograft …

Department of Family & Community Medicine Faculty Papers

Guideline-recommended screening programs exist for only a few single-cancer types, and these cancers represent less than one-half of all new cancer cases diagnosed each year in the U.S. In addition, these "single-cancer" standard of care (SoC) screening tests vary in accuracy, adherence, and effectiveness, though all are generally understood to lead to reductions in cancer-related mortality. Recent advances in high-throughput technologies and machine learning have facilitated the development of blood-based multi-cancer early detection (MCED) tests. The opportunity for early detection of multiple cancers with a single blood test holds promise in addressing the current unmet need in cancer screening. By …
