Children’s Nutrition Research Center Staff Publications

Background: Cluster randomized controlled trials (cRCTs) are increasingly used but must be analyzed carefully. We conducted a simulation study to evaluate the validity of a parametric bootstrap (PB) approach with respect to the empirical type I error rate for a cRCT with binary outcomes and a small number of clusters.

Methods: We simulated a case study with a binary (0/1) outcome, four clusters, and 100 subjects per cluster. To compare the validity of the test with respect to error rate, we simulated the same experiment with K=10, 20, and 30 clusters, each with 2,000 simulated datasets. To test the null …

Background: Angelman syndrome (AS) is a rare neurogenetic disorder present in approximately 1/12,000 individuals and characterized by developmental delay, cognitive impairment, motor dysfunction, seizures, gastrointestinal concerns, and abnormal electroencephalographic background. AS is caused by absent expression of the paternally imprinted gene UBE3A in the central nervous system. Disparities in the management of AS are a major problem in preparing for precision therapies and occur even in patients with access to experts and recognized clinics. AS patients receive care based on collective provider experience due to limited evidence-based literature. We present a consensus statement and comprehensive literature review that proposes a …

Transitions Of Care: Completeness Of The Interoperability Data Standard For Communication From Home Health Care To Primary Care., Edgar Chou, Paulina S Sockolow

Department of Medicine Faculty Papers

Data sharing is necessary to address communication deficits along the transitions of care among community settings. Evidence-based practice supports home healthcare (HHC) patients to see their primary care team within the first two weeks of hospital discharge to reduce rehospitalization risk. A small subset of patient data collected at HHC admission is mandated to be transmitted to primary care, predominantly by fax. Using qualitative analysis, we assessed completeness of the United States Core Data for Interoperability (USCDI) interoperability standard, as compared to the patient data collected by the primary care team (topics) and HHC (classes) during the initial visit; and …

The Social Cerebellum: A Large-Scale Investigation Of Functional And Structural Specificity And Connectivity, Athanasia Metoki, Yin Wang, Ingrid R Olson

2020-Current year OA Pubs

The cerebellum has been traditionally disregarded in relation to nonmotor functions, but recent findings indicate it may be involved in language, affective processing, and social functions. Mentalizing, or Theory of Mind (ToM), is the ability to infer mental states of others and this skill relies on a distributed network of brain regions. Here, we leveraged large-scale multimodal neuroimaging data to elucidate the structural and functional role of the cerebellum in mentalizing. We used functional activations to determine whether the cerebellum has a domain-general or domain-specific functional role, and effective connectivity and probabilistic tractography to map the cerebello-cerebral mentalizing network. We …

Spatiotemporal Dynamics Of Clonal Selection And Diversification In Normal Endometrial Epithelium., Manako Yamaguchi, Hirofumi Nakaoka, Kazuaki Suda, Kosuke Yoshihara, Tatsuya Ishiguro, Nozomi Yachida, Kyota Saito, Haruka Ueda, Kentaro Sugino, Yutaro Mori, Kaoru Yamawaki, Ryo Tamura, Sundaramoorthy Revathidevi, Teiichi Motoyama, Kazuki Tainaka, Roel G W Verhaak, Ituro Inoue, Takayuki Enomoto

It has become evident that somatic mutations in cancer-associated genes accumulate in the normal endometrium, but spatiotemporal understanding of the evolution and expansion of mutant clones is limited. To elucidate the timing and mechanism of the clonal expansion of somatic mutations in cancer-associated genes in the normal endometrium, we sequence 1311 endometrial glands from 37 women. By collecting endometrial glands from different parts of the endometrium, we show that multiple glands with the same somatic mutations occupy substantial areas of the endometrium. We demonstrate that "rhizome structures", in which the basal glands run horizontally along the muscular layer and multiple …

Faculty, Staff and Student Publications

Nociceptors are specialized sensory neurons that detect damaging or potentially damaging stimuli and are found in the dorsal root ganglia (DRG) and trigeminal ganglia. These neurons are critical for the generation of neuronal signals that ultimately create the perception of pain. Nociceptors are also primary targets for treating acute and chronic pain. Single-cell transcriptomics on mouse nociceptors has transformed our understanding of pain mechanisms. We sought to generate equivalent information for human nociceptors with the goal of identifying transcriptomic signatures of nociceptors, identifying species differences and potential drug targets. We used spatial transcriptomics to molecularly characterize transcriptomes of single DRG …

Faculty Publications

Social agents associated with cheerleading environments are increasingly linked to body image dissatisfaction (BID) and eating disorders (ED). This study examined ED risk across team type, squad type, and position. An additional purpose determined BID in clothing type (daily clothing, midriff uniform, and full uniform), and meta-perceptions from the perspective of peers (MP peers), parents (MP parents), and coaches (MP coaches). Female cheerleaders ( = 268) completed an online survey which included demographics, the Eating Attitudes Test-26, and pathogenic behavior questions. Body image perceptions were assessed by using the Sex-Specific Figural Stimuli Silhouettes. Overall, 34.4% of cheerleaders ( = 268; …

Prevention Is Political: Political Party Affiliation Predicts Perceived Risk And Prevention Behaviors For Covid-19, Marc T Kiviniemi, Heather Orom, Jennifer L Hay, Erika A Waters

2020-Current year OA Pubs

BACKGROUND: Many US politicians have provided mixed messages about the risks posed by SARS-CoV-2/COVID-19 and whether and to what extent prevention practices should be put in place to prevent transmission. This politicization of the virus and pandemic may affect individuals' risk perceptions and willingness to take precautions. We examined how political party affiliation relates to risk perception for one's own and other people's likelihood of SARS-CoV-2 infection/COVID-19 illness.

METHODS: We surveyed members of a nationally-representative, probability-sampling based survey panel (N = 410) to examine their risk perceptions, precautionary behaviors, and political party affiliation.

Videos Of Sipuleucel-T Programmed T Cells Lysing Cells That Express Prostate Cancer Target Antigens, Adam S Kibel, Brant A Inman, Russell K Pachynski, Tuyen Vu, Nadeem A Sheikh, Daniel P Petrylak

2020-Current year OA Pubs

Sipuleucel-T, an autologous cellular immunotherapy, was approved to treat metastatic castration-resistant prostate cancer in 2010 in the United States. Treatment with sipuleucel-T primes the immune system to target prostate acid phosphatase, which is expressed by prostate cancer cells, potentially leading to lysis of cancer cells. Expanding on previously reported indirect evidence of cell killing with sipuleucel-T treatment, we sought to provide direct evidence of cell lysis through visualization. We used advanced video technology and available samples of peripheral blood mononuclear cells from subjects enrolled in the STAMP trial (NCT01487863). Isolated CD8+ T cells were used as effector cells and cocultured …

Faculty, Staff and Students Publications

Distinct lung stem cells give rise to lung adenocarcinoma (LUAD) and squamous cell carcinoma (LUSC). ΔNp63, the p53 family member and p63 isoform, guides the maturation of these stem cells through the regulation of their self-renewal and terminal differentiation; however, the underlying mechanistic role regulated by ∆Np63 in lung cancer development has remained elusive. By utilizing a ΔNp63-specific conditional knockout mouse model and xenograft models of LUAD and LUSC, we found that ∆Np63 promotes non-small cell lung cancer by maintaining the lung stem cells necessary for lung cancer cell initiation and progression in quiescence. ChIP-seq analysis of lung basal cells, …

Echocardiographic And Clinical Predictors Of Cardiac Amyloidosis: Limitations Of Apical Sparing, Douglas Kyrouac, Walter Schiffer, Brandon Lennep, Nicole Fergestrom, Kathleen W Zhang, John Gorcsan Iii, Daniel J Lenihan, Joshua D Mitchell

2020-Current year OA Pubs

AIMS: The accuracy of an apical-sparing strain pattern on transthoracic echocardiography (TTE) for predicting cardiac amyloidosis (CA) has varied in prior studies depending on the underlying cohort. We sought to evaluate the performance of apical sparing and other TTE strain findings to screen for CA in an unselected population and determine the frequency that patients with echocardiographic concern for CA undergo evaluation for amyloidosis in clinical practice.

METHODS AND RESULTS: As strain is routinely performed at our institution on all clinical TTEs, we identified all TTEs performed from 2016 through 2019 with reported concern for CA or apical sparing. We …

Spatial Epidemiology: An Empirical Framework For Syndemics Research, Shikhar Shrestha, Cici X C Bauer, Brian Hendricks, Thomas J Stopka

Faculty, Staff and Student Publications

Syndemics framework describes two or more co-occurring epidemics that synergistically interact with each other and the complex structural social forces that sustain them leading to excess disease burden. The term syndemic was first used to describe the interaction between substance abuse, violence, and AIDS by Merrill Singer. A broader range of syndemic studies has since emerged describing the framework's applicability to other public health scenarios. With syndemic theory garnering significant attention, the focus is shifting towards developing robust empirical analytical approaches. Unfortunately, the complex nature of the disease-disease interactions nested within several social contexts complicates empirical analyses. In answering the …

Faculty, Staff and Students Publications

The detrimental effects of the coronavirus disease 2019 (COVID-19) pandemic have profoundly disrupted surgical care at health care facilities worldwide. At our tertiary pediatric hospital, we made substantial adjustments to surgical suite utilization and staff member scheduling to account for reductions in surgical volume, increased demand for staff members in other sectors of the hospital, and the highly infectious properties of the virus. Perioperative leaders took advantage of the pandemic's disruption to clinical activities to design and implement a new procedure-scheduling process to rectify the inefficiencies that had accumulated as the previous system evolved. The implementation of said directives was …

Effects Of Placebo Administration On Immune Mechanisms And Relationships With Central Endogenous Opioid Neurotransmission, Alan Prossin, Alisa Koch, Phillip Campbell, Geoffroy Laumet, Christian S Stohler, Robert Dantzer, Jon-Kar Zubieta

Faculty, Staff and Student Publications

Behavioral conditioning and expectation can have profound impact on animal and human physiology. Placebo, administered under positive expectation in clinical trials, can have potent effects on disease pathology, obscuring active medications. Emerging evidence suggests placebo-responsive neurotransmitter systems (e.g., endogenous opioid) regulate immune function by manipulating inflammatory proteins including IL-18, a potent pro-inflammatory, nociceptive cytokine implicated in pathophysiology of various diseases. Validation that neuroimmune interactions involving brain μ-opioid receptor (MOR) activity and plasma IL-18 underlie placebo analgesic expectation could have widespread clinical applications. Unfortunately, current lack of mechanistic clarity obfuscates clinical translation. To elucidate neuroimmune interactions underlying placebo analgesia, we exposed …

Faculty, Staff and Student Publications

Purpose:

Radiation epidemiology studies of childhood cancer survivors treated in the pre-computed tomography (CT) era reconstruct the patients’ treatment fields on computational phantoms. For such studies, the phantoms are commonly scaled to age at the time of radiotherapy treatment because age is the generally available anthropometric parameter. Several reference size phantoms are used in such studies, but reference size phantoms are only available at discrete ages (e.g.: newborn, 1, 5, 10, 15, and Adult). When such phantoms are used for RT dose reconstructions, the nearest discrete-aged phantom is selected to represent a survivor of a specific age. In this work, …
