Although obesity is prevalent among children in the United States, pharmacokinetic (PK) data for obese children are limited. Clindamycin is a commonly used antibiotic that may require dose adjustment in obese children due to its lipophilic properties. We performed a clindamycin population PK analysis using data from three separate trials. A total of 420 samples from 220 children, 76 of whom had a body mass index greater than or equal to the 95th percentile for age, were included in the analysis. Compared to other metrics, total body weight (TBW) was the most robust measure of body size. The final model …

Buprenorphine Physician Supply: Relationship With State-Level Prescription Opioid Mortality, Hannah K. Knudsen, Jennifer R. Havens, Michelle R. Lofwall, Jamie L. Studts, Sharon L. Walsh

Behavioral Science Faculty Publications

Background: Buprenorphine is an effective treatment for opioid use disorder but the supply of buprenorphine physicians is currently inadequate to address the nation’s prescription opioid crisis. Perception of need due to rising opioid overdose rates is one possible reason for physicians to adopt buprenorphine. This study examined associations between rates of growth in buprenorphine physicians and prescription opioid overdose mortality rates in US states.

Methods: The total buprenorphine physician supply and number of physicians approved to treat 100 patients (per 100,000 population) were measured from June 2013 to January 2016. States were divided into two groups: those with rates of …

An Integrated Transcriptomics-Guided Genome-Wide Promoter Analysis And Next-Generation Proteomics Approach To Mine Factor(S) Regulating Cellular Differentiation., Kamal Mandal, Samuel L Bader, Pankaj Kumar, Dipankar Malakar, David S Campbell, Bhola Shankar Pradhan, Rajesh K Sarkar, Neerja Wadhwa, Souvik Sensharma, Vaibhav Jain, Robert L Moritz, Subeer S Majumdar

Articles, Abstracts, and Reports

Differential next-generation-omics approaches aid in the visualization of biological processes and pave the way for divulging important events and/or interactions leading to a functional output at cellular or systems level. To this end, we undertook an integrated Nextgen transcriptomics and proteomics approach to divulge differential gene expression of infant and pubertal rat Sertoli cells (Sc).Unlike, pubertal Sc, infant Sc are immature and fail to support spermatogenesis. We found exclusive association of 14 and 19 transcription factor binding sites to infantile and pubertal states of Sc, respectively, using differential transcriptomics-guided genome-wide computational analysis of relevant promoters employing 220 Positional Weight Matrices …

In Vivo Characterization Of Cyp2d6*12, *29 And *84 Using Dextromethorphan As A Probe Drug: A Case Report., Andrea Gaedigk, Greyson P. Twist, Emily G. Farrow, Jennifer A. Lowry, Sarah E. Soden, Neil A. Miller

Manuscripts, Articles, Book Chapters and Other Papers

CYP2D6*84 was first described in a Black South African subject, however, its function remains unknown. Astrolabe, a probabilistic scoring tool developed in our laboratory to call genotypes from whole genome sequence, identified CYP2D6*84 in a trio. The father presented with intermediate metabolism when challenged with the CYP2D6 probe drug dextromethorphan (DM/dextrorphan [DX] = 0.0839). Since his second allele, CYP2D6*12, is nonfunctional, the observed activity is derived by CYP2D6*84. This finding suggests that the allele's hallmark P267H causes decreased activity toward DM and that this allele should receive a value of 0.5 for Activity Score calculations. The mother's DM/DX of 0.0543 …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Attrition in pediatric weight management negatively impacts treatment outcomes. A potentially modifiable contributor to attrition is unmet family expectations. This study aimed to evaluate the association between adolescent and parent/guardian treatment expectations and attrition.

PATIENTS AND METHODS: A prospective, nonrandomized, uncontrolled, single-arm pilot trial was conducted among 12 pediatric weight management programs in the Children's Hospital Association's FOCUS on a Fitter Future collaborative. Parents/guardians and adolescents completed an expectations/goals survey at their initial visit, with categories including healthier food/drinks, physical activity/exercise, family support/behavior, and weight management goals. Attrition was assessed at 3 months.

RESULTS: From January to August 2013, …

Evaluating Parents' Self-Efficacy For Diabetes Management In Pediatric Type 1 Diabetes., Amy E. Noser, Susana R. Patton, Jason Van Allen, Michael B. Nelson, Mark A. Clements

Manuscripts, Articles, Book Chapters and Other Papers

Objective: To examine the factor structure and construct validity of the Maternal Self-Efficacy for Diabetes Management Scale (MSED) in 135 youth ( Mage  = 13.50  ±  1.83 years), with type 1 diabetes mellitus.

Method: The study used exploratory factor analysis (EFA) to examine the factor structure and correlations to examine relationships among MSED factors and select parent and child diabetes-related health behaviors and outcomes.

Results: EFA identified an 11-item three-factor solution (χ 2 (25, n  = 133)  = 40.22, p  < .03, RMSEA = 0.07, CFI = 0.98, TLI = 0.97), with factors corresponding to parents' perceived ability to manage their child's diabetes (MSED-M), problem-solve issues surrounding glycemic control (MSED-P), and teach their child about diabetes care (MSED-T). Correlational analyses revealed significant associations between the MSED-M and MSED-T and parent-reported optimism and youth's diabetes-specific self-efficacy. The MSED-T was also associated with glycated hemoglobin and self-monitoring blood glucose.

Conclusions: Results provide preliminary evidence for the reliability and validity of a three-factor solution of the MSED.

Genomic Contraindications For Heart Transplantation., Danton S. Char, Gabriel Lázaro-Muñoz, Aliessa Barnes, David Magnus, Michael J. Deem, John Lantos

Manuscripts, Articles, Book Chapters and Other Papers

Genome sequencing raises new ethical challenges. Decoding the genome produces new forms of diagnostic and prognostic information; however, the information is often difficult to interpret. The connection between most genetic variants and their phenotypic manifestations is not understood. This scenario is particularly true for disorders that are not associated with an autosomal genetic variant. The analytic uncertainty is compounded by moral uncertainty about how, exactly, the results of genomic testing should influence clinical decisions. In this Ethics Rounds, we present a case in which genomic findings seemed to play a role in deciding whether a patient was to be listed …

Increasing Ed Use Of Jet Injection Of Lidocaine For Iv-Related Pain Management., Shobhit Jain, Mary A. Hegenbarth, Sharon Humiston, Erin Gunter, Lynn Anson, Joan Giovanni

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND AND OBJECTIVE: Venipuncture is a leading cause of procedural pain for children. Jet injection of lidocaine (JIL; J-Tip) has been demonstrated to be effective in controlling intravenous (IV) placement-related pain and, due to its rapid onset, is particularly suited to emergency department (ED) use. Our objective was to increase JIL use with IV placements in our ED from 11% at baseline to 50% within 12 months.

METHODS: We initiated the project at our urban, tertiary pediatric ED in July 2014. We surveyed medical and nursing teams to identify barriers to JIL use. We initiated changes at monthly intervals: (1) …

A Statistical Method For The Conservative Adjustment Of False Discovery Rate (Q-Value)., Yinglei Lai

Epidemiology Faculty Publications

BACKGROUND: q-value is a widely used statistical method for estimating false discovery rate (FDR), which is a conventional significance measure in the analysis of genome-wide expression data. q-value is a random variable and it may underestimate FDR in practice. An underestimated FDR can lead to unexpected false discoveries in the follow-up validation experiments. This issue has not been well addressed in literature, especially in the situation when the permutation procedure is necessary for p-value calculation.

RESULTS: We proposed a statistical method for the conservative adjustment of q-value. In practice, it is usually necessary to calculate p-value by a permutation procedure. …

Articles, Abstracts, and Reports

Purpose B-cell leukemia/lymphoma-2 (BCL-2) overexpression is common in many non-Hodgkin lymphoma (NHL) subtypes. A phase I trial in patients with NHL was conducted to determine safety, pharmacokinetics, and efficacy of venetoclax, a selective, potent, orally bioavailable BCL-2 inhibitor. Patients and Methods A total of 106 patients with relapsed or refractory NHL received venetoclax once daily until progressive disease or unacceptable toxicity at target doses from 200 to 1,200 mg in dose-escalation and safety expansion cohorts. Treatment commenced with a 3-week dose ramp-up period for most patients in dose-escalation cohorts and for all patients in safety expansion. Results NHL subtypes included …

Are There Multiple Kinds Of Episodic Memory? An Fmri Investigation Comparing Autobiographical And Recognition Memory Tasks, Hung-Yu Chen, Adrian W. Gilmore, Steven M. Nelson, Kathleen B. Mcdermott

Open Access Publications

What brain regions underlie retrieval from episodic memory? The bulk of research addressing this question with fMRI has relied upon recognition memory for materials encoded within the laboratory. Another, less dominant tradition has used autobiographical methods, whereby people recall events from their lifetime, often after being cued with words or pictures. The current study addresses how the neural substrates of successful memory retrieval differed as a function of the targeted memory when the experimental parameters were held constant in the two conditions (except for instructions). Human participants studied a set of scenes and then took two types of memory test …

Using A Respiratory Navigator Significantly Reduces Variability When Quantifying Left Ventricular Torsion With Cardiovascular Magnetic Resonance, Sean M. Hamlet, Christopher M. Haggerty, Jonathan D. Suever, Gregory J. Wehner, Kristin N. Andres, David K. Powell, Richard J. Charnigo, Brandon K. Fornwalt

Electrical and Computer Engineering Faculty Publications

Background: Left ventricular (LV) torsion is an important indicator of cardiac function that is limited by high inter-test variability (50% of the mean value). We hypothesized that this high inter-test variability is partly due to inconsistent breath-hold positions during serial image acquisitions, which could be significantly improved by using a respiratory navigator for cardiovascular magnetic resonance (CMR) based quantification of LV torsion.

Methods: We assessed respiratory-related variability in measured LV torsion with two distinct experimental protocols. First, 17 volunteers were recruited for CMR with cine displacement encoding with stimulated echoes (DENSE) in which a respiratory navigator was used to measure …

Cytomegalovirus Serostatus, Inflammation, And Antibody Response To Influenza Vaccination In Older Adults: The Moderating Effect Of Beta Blockade, Rebecca G. Reed, Richard N. Greenberg, Suzanne C. Segerstrom

Psychology Faculty Publications

Cytomegalovirus (CMV) has been implicated as a factor in immunosenescence, including poor antibody response to vaccination and higher immune activation and inflammation. Some people may be more or less vulnerable to the negative effects of CMV. The present investigation tested the effects of beta-blocker use and chronological age on the associations between CMV and immunity in adults aged 60–91 (N=98; 69% CMV seropositive) who were administered the trivalent influenza vaccine for up to 5 years. Peak antibody response, corrected for baseline, and spring (persistent) antibody response, corrected for peak, were assessed, as well as beta-2 microglobulin (β2μ) and interleukin-6 (IL-6). …
