Central Hypothyroidism Following Neonatal Graves' Presentation, Emily Metzinger, Kelsee Halpin

Posters

Background: Neonatal Graves’ disease is a rare disorder of neonatal autoimmune hyperthyroidism secondary to the transplacental passage of thyroid-stimulating hormone receptor antibodies. Although neonatal Graves’ disease is transient, it is associated with cardiac dysfunction, intrauterine growth restriction, prematurity, craniosynostosis, and developmental delay and can be life-threatening. Additionally, infants with neonatal Graves’ disease can rarely present with primary or central hypothyroidism later in infancy or childhood. This is suspected to be due to the disruption in the hypothalamic-pituitary-thyroid axis or development of the thyroid gland. Clinical Case: Here we describe a case of neonatal Graves’ disease that has been complicated by …

Supporting Fathers And Partners In The Nicu, Tiffany Gladdis

Posters

The NICU can be an incredibly stressful environment for both the infant and its parents. Unlike many traumatic events, the NICU experience can often feel like an ongoing trauma, with the stay often involving highs and lows, new diagnoses, changes in prognosis, multiple procedures, and a rollercoaster of emotions. Additionally, the NICU can also trigger trauma responses for parents who have had previous traumatic experiences. When working with families in the NICU, it is important to use a Trauma Informed Care lens to ensure that the whole family is understood and adequately supported (Sanders & Hall, 2007). Perinatal Mood and …

Recalcitrant Cutaneous Mastocytosis Treated With Genetically Informed Targeted Therapy: A Case Report, Laura Gleason, Volkan Tekmen, Alexa Cohen, Safiyyah Bhatti, Burcu Beksac, Jisun Cha, Pierluigi Porcu, Neda Nikbakht

Department of Dermatology and Cutaneous Biology Faculty Papers

Introduction:

Mastocytosis, a clonal proliferation of mast cells commonly involving the skin and bone marrow, has a varied clinical presentation ranging from cutaneous lesions to systemic disease. Cutaneous mastocytosis is managed symptomatically, but systemic mastocytosis is treated with targeted therapy against the mutated receptor tyrosine kinase c-KIT, the pathogenic driver of mastocytosis. However, there are no guidelines for the treatment of cutaneous mastocytosis refractory to symptomatic management.

We herein report a method to select genetically informed therapy for symptomatic and recalcitrant cutaneous mastocytosis.

Case presentation:

We performed a mutational analysis of dermal mast cells after enrichment by laser capture in …

Birth Weight Moderates The Association Between Obesity And Mortality Rate, Gregory Pavela, Nengjun Yi, Luis Mestre, Pengcheng Xun, David B Allison

Children’s Nutrition Research Center Staff Publications

Purpose: The strength of the association between obesity and mortality rate (MR) varies by body mass index (BMI) and sociodemographic groups. We test the hypothesis that the association between obesity and MR varies, in part, due to the moderating effect of parental BMI and birth weight.

Methods: Data come from the 1958 National Child Development Study, an ongoing longitudinal dataset initiated in 1958 with baseline measures of birth weight from 18,059 infants born in Great Britain over 1 week. We tested whether the association between BMI and MR was moderated by parental BMI and birth weight using generalized additive proportional …

Moderators Of Resistance-Based Exercise Programs' Effect On Sarcopenia-Related Measures In Men With Prostate Cancer Previously Or Currently Undergoing Androgen Deprivation Therapy: An Individual Patient Data Meta-Analysis, Pedro Lopez, Robert U. Newton, Dennis R. Taaffe, Kerri Winters-Stone, Daniel A. Galvão, Laurien M. Buffart

Research outputs 2022 to 2026

Introduction: Older men with prostate cancer are commonly affected by reductions in lean mass and physical function following androgen deprivation therapy (ADT). Resistance-based exercise programs are critical to counteract the musculoskeletal toxicities derived from prostate cancer treatment and aging. However, there is significant variability in the effects of exercise interventions. Examining demographic and clinical moderators of exercise effects in this patient group can assist in identifying which subgroups of patients benefit most. Therefore, we examined the effects and moderators of resistance-based exercise programs on sarcopenia-related outcomes that included lean mass, skeletal muscle index, physical function, and muscle strength in older …

Kinetics Of Wound Development And Healing Suggests A Skin-Stabilizing Effect Of Allogeneic Abcb5+ Mesenchymal Stromal Cell Treatment In Recessive Dystrophic Epidermolysis Bullosa, Elke Niebergall-Roth, Kathrin Dieter, Cristina Daniele, Silvia Fluhr, Maria Khokhrina, Ines Silva, Christoph Ganss, Markus H. Frank, Mark A. Kluth

Research outputs 2022 to 2026

Recessive dystrophic epidermolysis (RDEB) is a rare, inherited, and currently incurable skin blistering disorder characterized by cyclically recurring wounds coexisting with chronic non-healing wounds. In a recent clinical trial, three intravenous infusions of skin-derived ABCB5+ mesenchymal stromal cells (MSCs) to 14 patients with RDEB improved the healing of wounds that were present at baseline. Since in RDEB even minor mechanical forces perpetually provoke the development of new or recurrent wounds, a post-hoc analysis of patient photographs was performed to specifically assess the effects of ABCB5+ MSCs on new or recurrent wounds by evaluating 174 wounds that occurred after baseline. During …

Determinants Of First‐Ever Stroke Severity In West Africans: Evidence From The Siren Study, Oladimeji Adebayo, Onoja Akpa, Osahon J. Asowata, Adekunle Fakunle, Fred S. Sarfo, Albert Akpalu, Kolawole Wahab, Reginald Obiako, Morenikeji Komolafe, Philip Adebayo

Internal Medicine, East Africa

Background: Baseline stroke severity is probably partly responsible for poor stroke outcomes in sub-Saharan Africa. However, there is a paucity of information on determinants of stroke severity among indigenous Africans. We sought to identify the factors associated with stroke severity among West Africans in the SIREN (Stroke Investigative Research and Educational Networks) study.

Methods and Results: Stroke was diagnosed clinically and confirmed with brain neuroimaging. Severe stroke was defined as a Stroke Levity Scale score of ≤5. A multivariate logistic regression model was constructed to identify factors associated with stroke severity at 95% CI and a nominal cutoff of 5% …

A Review Of The Current State Of Global Surgical Oncology And The Role Of Surgeons Who Treat Cancer: Our Profession’S Imperative To Act Upon A Worldwide Crisis In Evolution, Aaron C. Saunders, Miriam Mutebi, T. Subramanyeshwar Rao

General Surgery, East Africa

Worldwide, the capacity of healthcare systems and physician workforce is woefully inadequate for the surgical treatment of cancer. With major projected increases in the global burden of neoplastic disease, this inadequacy is expected to worsen, and interventions to increase the workforce of surgeons who treat cancer and strengthen the necessary supporting infrastructure, equipment, staffing, financial and information systems are urgently called for to prevent this inadequacy from deepening. These efforts must also occur in the context of broader healthcare systems strengthening and cancer control plans, including prevention, screening, early detection, safe and effective treatment, surveillance, and palliation. The cost of …

Leveraging A Surrogate Outcome To Improve Inference On A Partially Missing Target Outcome, Zachary R Mccaw, Sheila M Gaynor, Ryan Sun, Xihong Lin

Faculty, Staff and Student Publications

Sample sizes vary substantially across tissues in the Genotype-Tissue Expression (GTEx) project, where considerably fewer samples are available from certain inaccessible tissues, such as the substantia nigra (SSN), than from accessible tissues, such as blood. This severely limits power for identifying tissue-specific expression quantitative trait loci (eQTL) in undersampled tissues. Here we propose Surrogate Phenotype Regression Analysis (Spray) for leveraging information from a correlated surrogate outcome (eg, expression in blood) to improve inference on a partially missing target outcome (eg, expression in SSN). Rather than regarding the surrogate outcome as a proxy for the target outcome, Spray jointly models the …

Incorporating Sexual And Gender Minority Patient Care Competencies: A Case Based Curriculum For Caring For Gender Diverse Youth, Eileen Cichoskikelly, Suzanne Kingery, Susan Sawning

Faculty and Staff Scholarship

There is a gap in medical education training content specifically focused on the care of Sexual and Gender Minority (SGM) people and people with Differences in Sex Development (DSD). Inadequate training contributes to suboptimal health care access, utilization, and experiences among SGM-DSD people. Improving medical education training can be challenging as many clinician educators received sparse instruction themselves in these areas and there are limited teaching resources that expand beyond didactic instruction. In 2014 the Association of American Medical Colleges (AAMC) Advisory Committee on Sexual Orientation, Gender Identity, and Sex Development published a landmark document identifying 30 specifiers of competence …

Leucine-Rich Alpha-2-Glycoprotein 1 Is A Systemic Biomarker Of Early Brain Injury And Delayed Cerebral Ischemia After Subarachnoid Hemorrhage, Jude P J Savarraj, Devin W Mcbride, Eunsu Park, Sarah Hinds, Atzhiry Paz, Aaron Gusdon, Ren Xuefang, Sheng Pan, Hilda Ahnstedt, Gabriela Delevati Colpo, Eunhee Kim, Zhongming Zhao, Louise Mccullough, Huimahn Alex Choi

Faculty, Staff and Student Publications

BACKGROUND: After subarachnoid hemorrhage (SAH), early brain injury (EBI) and delayed cerebral ischemia (DCI) lead to poor outcomes. Discovery of biomarkers indicative of disease severity and predictive of DCI is important. We tested whether leucine-rich alpha-2-glycoprotein 1 (LRG1) is a marker of severity, DCI, and functional outcomes after SAH.

METHODS: We performed untargeted proteomics using mass spectrometry in plasma samples collected at < 48 h of SAH in two independent discovery cohorts (n = 27 and n = 45) and identified LRG1 as a biomarker for DCI. To validate our findings, we used enzyme-linked immunosorbent assay and confirmed this finding in an internal validation cohort of plasma from 72 study participants with SAH (22 DCI and 50 non-DCI). Further, we investigated the relationship between LRG1 and markers of EBI, DCI, and poor functional outcomes (quantified by the modified Rankin Scale). We also measured cerebrospinal fluid (CSF) levels of LRG1 and investigated its relationship to EBI, DCI, and clinical outcomes.

RESULTS: Untargeted proteomics revealed higher plasma LRG1 levels across EBI severity and DCI in both discovery cohorts. In the validation cohort, the levels of LRG1 were higher in the DCI group compared with the non-DCI group (mean (SD): …

Characterization Of The Cholesterol Biosynthetic Pathway In Dioscorea Transversa, Lauren J Salisbury, Stephen J Fletcher, Jeanette E Stok, Luke R Churchman, Joanne T Blanchfield, James J De Voss

Faculty, Staff and Student Publications

Cholesterol is the precursor of bioactive plant metabolites such as steroidal saponins. An Australian plant, Dioscorea transversa, produces only two steroidal saponins: 1β-hydroxyprotoneogracillin and protoneogracillin. Here, we used D. transversa as a model in which to elucidate the biosynthetic pathway to cholesterol, a precursor to these compounds. Preliminary transcriptomes of D. transversa rhizome and leaves were constructed, annotated, and analyzed. We identified a novel sterol side-chain reductase as a key initiator of cholesterol biosynthesis in this plant. By complementation in yeast, we determine that this sterol side-chain reductase reduces Δ^24,28 double bonds required for phytosterol biogenesis as well …
