Diagnostic Accuracy Of The Stopbang Questionnaire Against Polysomnography For The Screening Of Obstructive Sleep Apnea In A Tertiary Hospital In Kenya., Sandra Obaje Maseno Aug 2025

Diagnostic Accuracy Of The Stopbang Questionnaire Against Polysomnography For The Screening Of Obstructive Sleep Apnea In A Tertiary Hospital In Kenya., Sandra Obaje Maseno

Master of Medicine in Internal Medicine

BACKGROUND: Obstructive sleep apnea is a syndrome of upper airway and neuromuscular dysfunction during sleep that subsequently causes interruption of normal breathing. Polysomnography is the reference test for the diagnosis of obstructive sleep apnea. Obstructive sleep apnea can be categorised as mild, moderate or severe based on an apnea-hypopnea index (AHI) on polysomnography. The recommended treatment using Continuous Positive Airway Pressure lowers morbidity and mortality rates. The STOPBANG questionnaire has been used as a screening tool for obstructive sleep apnea due to its easy and concise approach. However, even with the increasing prevalence of obstructive sleep apnea and its risk …

Chronic Cluster Headache Is A Rare Disease: Implications For Diagnosis, Treatment And Public Health, Hsiangkuo Yuan, Jan Hoffmann, Elena Ruiz De La Torre, Michael J. Marmura, Mario F. P. Peres

Department of Jefferson Headache Center Papers and Presentations

Cluster headache (CH) is a rare and painful primary headache disorder characterized by severe unilateral pain and cranial autonomic symptoms. This perspective examines the epidemiological evidence supporting the classification of chronic cluster headache (CCH) as a rare disease, noting a prevalence of CH of approximately 124 per 100,000 individuals, with only 3.5-13.7% manifesting CCH. This prevalence meets criteria established by both the US Food and Drug Administration and European Medicines Agency for rare disease designation. The rarity of CCH creates substantial clinical and research challenges, including prolonged diagnostic delays, limited research funding and a dearth of approved treatments. The economic …

The Tree That Would Not Fall: An Educator’S Autoethnographic Journey Of Healing Through Words, Raeanna Marie Carlson

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

To say the world has changed since the 2020 COVID-19 shut down is to minimize the micro and macro social changes that infiltrated the school system. In the wake of it all, we find a landscape marred by a both rising teacher attrition and struggling student motivation. This autoethnographic dissertation explores the deeply personal experience tethered to a deeply problematic system that contributes to not only teacher burnout but what I came to know as teacher demoralization. Personal traumas of teachers profoundly impact their experience in the classroom, and as I examined my own near departure from the classroom, I …

Hormonal Modulation Of Sexual Approach And Avoidance Among Women With A History Of Sexual Trauma, Anneliis Susan Sartin-Tarm Aug 2025

Hormonal Modulation Of Sexual Approach And Avoidance Among Women With A History Of Sexual Trauma, Anneliis Susan Sartin-Tarm

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

A history of sexual trauma places women at a high risk for sexual dysfunction and other health sequelae, yet the influence of ovarian hormones in this population is poorly understood. This dissertation tested the theory that the effects of ovarian hormones are mediated by cognitive approach-avoidance systems to shape sexual well-being, and that this process is moderated by sexual trauma history. This was investigated across three studies examining the menstrual cycle, hormonal contraceptive use, and menopause. Across each chapter, I present complementary evidence demonstrating that hormones interact with the interpretation of ambiguous internal and external cues with respect to sexual …


Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder Aug 2025

Chronic Pain After Traumatic Brain Injury: Treatment Experiences And Effects On Cognition And Functioning, Rachael L. Snyder

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Traumatic brain injury (TBI) can contribute to changes in cognitive and emotional functioning, quality of life, and psychosocial reintegration. Chronic pain is a common consequence of TBI which can uniquely impact such outcomes. Still, the exact nature of the contribution of pain on post-TBI outcomes remains unclear, and there are few existing studies exploring the treatment journey for chronic pain and injury rehabilitation through qualitative methods, specifically individual interviews with TBI survivors. This study aimed to document these narratives and to identify precisely how the experiences of TBI survivors seeking treatments, rather than the treatments themselves, impact outcomes. It also …

School of Medicine Faculty Publications

Cholesterol crystal embolization (CCE) results from the release of cholesterol crystals from ruptured atherosclerotic plaques into circulation, resulting in the occlusion of small arteries and arterioles in various organs. Ischemia triggers a systemic inflammatory response resulting in vascular obstruction and organ dysfunction. Kidneys are often involved because of the proximity to the aorta and CCE in the kidneys can result in acute, sub-acute, or chronic kidney disease. There are many known risk factors for renal involvement of CCE, including iatrogenic and spontaneous causes. The pathophysiology of CCE includes complex pathways that lead to acute and chronic effects that can have …

Development And Implementation Of An Ob/L&D Sbar Framework To Enhance Communication Between Obstetric Nurses And Anesthesia Providers: A Quality Improvement Initiative, Jenna E. Bigam, Laina J. Uzarski

Doctor of Nurse Anesthesia Practice (DNAP) Manuscripts

Effective communication between obstetric (OB) nurses and anesthesia providers is critical to ensure patient safety during epidural placements in labor and delivery (L&D) settings. At a large teaching hospital, communication gaps were identified when OB nurses requested anesthesia for epidural placements without consistently providing vital patient information. The lack of structured communication can result in important details being overlooked, which may lead to delays in care and potential patient harm. To address this, the SBAR (Situation, Background, Assessment, Recommendation) communication framework was implemented to standardize and improve information exchange. This Doctorate of Nurse Anesthesia Practice (DNAP) project aimed to enhance …

The Impact Of Gender, Training Year, Medical Specialty And The Covid-19 Pandemic On Resident Wellness, Sara Beachy, Jessica Luzier, Chantel Weisenmuller, Kathleen Bors, Mary Ann Maurer, Amna Anees, Tiffany Lasky, Lisa Calderwood

Department of Family & Community Medicine Faculty Papers

INTRODUCTION: Data are limited as to which factors most strongly impact medical trainees' well-being, and few studies have assessed trainee's wellness at multiple time points during the COVID-19 pandemic. Additionally, much research has not taken an intersectional approach to understanding the ways in which different facets of a resident's identity impact their wellness. Thus, more person-centred, probability-driven statistical approaches that can produce distinct heterogenous groups of individuals are warranted to understand the way in which different identities are associated with resident wellness scores.

METHODS: A latent profile analysis was conducted using institutional data from resident surveys administered from 2019 to …

Faculty, Staff and Students Publications

Ovulation is induced by the luteinizing hormone (LH) surge and accompanied by granulosa cell luteinization and ovarian angiogenesis. Semaphorin 3E (Sema3E)-Plexin-D1 pathway regulates angiogenesis in other tissues, but its role in the ovary is unknown. Evidence indicates that Sema3E-Plexin-D1 pathway plays an important role in the mouse ovary. The expression of Sema3E and its receptor, Plexin-D1, is dynamically regulated in the mouse ovary downstream of the LH surge. This regulation requires the modulation of chromatin accessibility by CCAAT/enhancer-binding proteins α and β. Intraovarian injection of recombinant Sema3E results in reduced ovulation, impaired corpus luteum formation, and aberrant ovarian angiogenesis. These …

Faculty, Staff and Students Publications

Drug induced neutropenia is an uncommon but potentially serious side effect in children receiving prolonged β-lactam antibiotic therapy. Management of β-lactam induced neutropenia in children remains challenging and often requires antibiotic therapy interruption or modification. There are limited data in pediatric patients about use of granulocyte-colony stimulating factor (G-CSF) for the treatment of drug induced neutropenia. We report the use of G-CSF for β-lactam induced neutropenia in four pediatric patients between the ages of 3 months and 18 years with bacterial meningitis in this case series.

Contribution Of Pannexin Channels To Afterimage Signals In The Amphibian Retina, Yufei Liu, Nick Libian, Zheng Jiang, Wen Shen Aug 2025

Contribution Of Pannexin Channels To Afterimage Signals In The Amphibian Retina, Yufei Liu, Nick Libian, Zheng Jiang, Wen Shen

Faculty, Staff and Students Publications

Pannexin 1 (Panx1) forms large-pore, single-membrane channels that connect the intracellular and extracellular environments, permitting the passage of ions and small molecules such as ATP. Panx1 channels are involved in diverse signaling pathways that contribute to various physiological processes, including sensory processing, although their precise mechanisms of action remain incompletely understood. This study reveals a Panx1-mediated mechanism regulating visual signal processing in the amphibian retina. Using immunolabeling and confocal imaging, we localized Panx1 channels in the cone-dominated On-bipolar cells, specifically at both somas and axon terminals. Whole-cell patch-clamp recordings showed that these channels have high permeability to Cl⁻ ions, which …
