Genealogy-Based Trait Association With Locater Boosts Power At Loci With Allelic Heterogeneity, Xinxin Wang, Ryan Christ, Erica Young, Chul Joo Kang, Indraniel Das, Edward A Belter, Markku Laakso, Louis J M Aslett, David Steinsaltz, Nathan O Stitziel, Ira M Hall

2020-Current year OA Pubs

A key methodological challenge for genome-wide association studies is how to leverage haplotype diversity and allelic heterogeneity to improve trait association power, especially in noncoding regions where it is difficult to predict variant impacts and define functional units for variant aggregation. Genealogy-based association methods have the potential to bridge this gap by testing combinations of common and rare haplotypes based purely on their ancestral relationships. In parallel work, we have developed an efficient local ancestry inference engine and a novel statistical method (LOCATER) for combining signals present on different branches of a locus-specific haplotype tree. Here, we develop a genome-wide …

2020-Current year OA Pubs

Elucidating the genetic contributions to Parkinson's disease aetiology across diverse ancestries is a critical priority for the development of targeted therapies in a global context. We conducted the largest sequencing characterization of potentially disease-causing, protein-altering and splicing mutations in 710 cases and 11 827 controls from genetically predicted African or African admixed ancestries. We explored copy number variants (CNVs) and runs of homozygosity in prioritized early onset and familial cases. Our study identified rare GBA1 coding variants to be the most frequent mutations among patients with Parkinson's disease, with a frequency of 4% in our case cohort. Of the 18 …

Barriers To Palliative Care Access In Rural South Dakota: A Policy And System-Level Analysis, Harshavardhan Kadarkaraisamy

A Quality Improvement Project To Strengthen Hospice Spiritual Care Delivery, Patricia Boudreau

Doctoral Projects

Spiritual care is an essential component of holistic end-of-life nursing, yet it is inconsistently provided in home hospice settings. For this Doctor of Nursing Practice (DNP) quality improvement project, we developed and implemented the Compassionate Spiritual Comfort Integration Program (CSCI), a brief, theory-based educational intervention to strengthen hospice nurses' spiritual care practices. Grounded in Kolcaba's Comfort Theory and Jinpa's Compassion Framework, the CSCI was delivered as a prerecorded webinar. A quasi-experimental single–group pretest–posttest design was used to evaluate changes in spiritual care behaviors, measured with the 17-item Nurse Spiritual Care Therapeutics Scale (NSCTS) and a single-item confidence measure. Twenty-two nurses …

Logistic Regression For Estimating Functional Effects With Spatial Transcriptomics, Michael Barkasi, Cody Nhan Pham, Demetrios Neophytou, Hysell V Oviedo

2020-Current year OA Pubs

Spatial transcriptomics (ST) unlocks potential for studying gene functions in processes that depend on orchestration of transcription across space. However, analysis tools for ST remain aimed at data exploration, with few resources for hypothesis testing. What's missing is a way to test whether a factor of interest affects functionally relevant parameters of a gene's spatial distribution. We present a tool to fill this gap, which we call a warped sigmoidal Poisson-process mixed-effects (WSP, pronounced "wisp") model. WSP models are the first ST tool allowing researchers to test critical questions without bespoke preprocessing pipelines for identifying key spatial parameters. By aligning …

Genecov, Christopher F. Drescher, Heather Bruschwein, Chelsi N. Nurse, Katherine Lawliss, Darcy C. Esiason, Gunnar H. Esiason

Department of Psychiatry and Human Behavior Faculty Papers

BACKGROUND: Existing mental health self-report measures have been criticized for over-simplification, lack of CF-specific focus, susceptibility to measurement reactivity bias, and conflation of symptoms of anxiety and/or depression with CF-related symptoms and/or treatment side effects. The CF Mental Health and Wellness Questionnaire (CFMHWQ) is a 25-item measure assessing CF-specific mental health burden symptoms.

METHODS: To examine common underlying factors contributing to scores on the CFMHWQ, principal component analysis (PCA) was conducted of all 25 items. We conducted cross-validation of CFMHWQ principal components, examining unadjusted correlations between each principal component, demographic characteristics (age and biological sex), negative affect (mean rank global …

Mitochondrial Etf Insufficiency Drives Neoplastic Growth By Selectively Optimizing Cancer Bioenergetics, David Papadopoli, Sergej Djuranovic, Et Al.

2020-Current year OA Pubs

Mitochondrial electron transport flavoprotein (ETF) insufficiency causes metabolic diseases known as a multiple acyl-CoA dehydrogenase deficiency (MADD). In contrast to muscle, ETFDH is a non-essential gene in acute lymphoblastic leukemia NALM6 cells, and its expression is reduced across human cancers. In various human cancer cell lines and mouse models, ETF insufficiency caused by decreased ETFDH expression limits flexibility of OXPHOS fuel utilisation but paradoxically increases bioenergetics and accelerates neoplastic growth via activation of the mTORC1/BCL-6/4E-BP1 axis. Collectively, these findings reveal that while ETF insufficiency is rare and has detrimental effects in non-malignant tissues, it is common in neoplasia, where ETFDH …
