Paediatrics Publications

Background

Claes-Jensen syndrome is an X-linked inherited intellectual disability caused by mutations in the

Results

Genome-wide DNA methylation analysis of 7 male patients affected with Claes-Jensen syndrome and 56 age- and sex-matched controls identified a specific DNA methylation defect (epi-signature) in the peripheral blood of these patients, including 1769 individual CpGs and 9 genomic regions. Six healthy female carriers showed less pronounced but distinctive changes in the same regions enabling their differentiation from both patients and controls. Highly specific computational model using the most significant methylation changes demonstrated 100% accuracy in differentiating patients, carriers, and controls in the training cohort, …

Word-List Intrusion Errors Predict Progression To Mild Cognitive Impairment, Kelsey R Thomas, Joel Eppig, Emily C Edmonds, Diane M Jacobs, David J Libon, Rhoda Au, David P Salmon, Mark W Bondi, Alzheimer’S Disease Neuroimaging Initiative

Rowan-Virtua School of Osteopathic Medicine Departmental Research

OBJECTIVE: Preclinical Alzheimer's disease (AD) defined by a positive AD biomarker in the presence of normal cognition is presumed to precede mild cognitive impairment (MCI). Subtle cognitive deficits and cognitive inefficiencies in preclinical AD may be detected through process and error scores on neuropsychological tests in those at risk for progression to MCI.

METHOD: Cognitively normal participants (n = 525) from the Alzheimer's Disease Neuroimaging Initiative were followed for up to 5 years and classified as either stable normal (n = 305) or progressed to MCI (n = 220). Cox regressions were used to determine whether baseline process scores on …

Scope: Body weight responds variably to the intake of dairy foods. Genetic variation may contribute to inter‐individual variability in associations between body weight and dairy consumption.

Methods and results: A genome‐wide interaction study to discover genetic variants that account for variation in BMI in the context of low‐fat, high‐fat and total dairy intake in cross‐sectional analysis was conducted. Data from nine discovery studies (up to 25 513 European descent individuals) were meta‐analyzed. Twenty‐six genetic variants reached the selected significance threshold (p‐interaction <10⁻⁷⁾, and six independent variants (LINC01512‐rs7751666, PALM2/AKAP2‐rs914359, ACTA2‐rs1388, PPP1R12A‐rs7961195, LINC00333‐rs9635058, …

Interaction Between Pre-Treatment Drug Use And Heterogeneity Of Psychiatric Diagnosis Predicts Outcomes In Outpatients With Co-Occurring Disorders., Oladunni Oluwoye, Katherine Hirchak, Emily Leickly, Jordan Skalisky, Sterling M Mcpherson, Debra Srebnik, John M Roll, Richard K Ries, Michael G Mcdonell

Articles, Abstracts, and Reports

We examined whether the interaction of baseline stimulant use, assessed by urine drug tests, and type of serious mental illness (SMI) diagnosis predicted stimulant use in a trial of contingency management (CM). The interaction between baseline stimulant use and SMI diagnoses was significant in the overall sample (p=0.002) when controlling for the main effects of treatment condition, baseline stimulant use, and SMI diagnosis. Similar results were also found within the CM sample. Individuals with bipolar disorder were more or less likely, depending on their baseline stimulant-drug test results, to use stimulants during treatment compared to those with other SMI diagnoses.

Reproductive Steroids And Adhd Symptoms Across The Menstrual Cycle, Bethan A. Roberts, Tory Eisenlohr-Moul, Michelle M. Martel

Psychology Faculty Publications

Although Attention-Deficit/Hyperactivity Disorder shows (ADHD) male predominance, females are significantly impaired and exhibit additional comorbid disorders during adolescence. However, no empirical work has examined the influence of cyclical fluctuating steroids on ADHD symptoms in women. The present study examined estradiol (E2), progesterone (P4), and testosterone (T) associations with ADHD symptoms across the menstrual cycle in regularly-cycling young women (N=32), examining trait impulsivity as a moderator. Women completed a baseline measure of trait impulsivity, provided saliva samples each morning, and completed an ADHD symptom checklist every evening for 35 days. Results indicated decreased levels of E2 in the context of increased …

Treated Hypothyroidism Is Associated With Cerebrovascular Disease But Not Alzheimer's Disease Pathology In Older Adults, Willa D. Brenowitz, Fang Han, Walter A. Kukull, Peter T. Nelson

Pathology and Laboratory Medicine Faculty Publications

Thyroid hormone (TH) disease is common among older adults and is associated with cognitive impairment. However, pathologic correlates are not well understood. We studied pathologic and clinical factors associated with hypothyroidism, the most common form of TH disease, in research subjects seen annually for clinical evaluations at U.S. Alzheimer’s Disease Centers. Thyroid disease and treatment status were assessed during clinician interviews. Among autopsied subjects, there were 555 participants with treated hypothyroidism and 2,146 with no known thyroid disease; hypothyroidism was associated with severe atherosclerosis (OR=1.35 95% CI: 1.02, 1.79) but not Alzheimer’s disease (AD) pathologies (amyloid plaques or neurofibrillary tangles). …

Open Access Publications

PURPOSE: To assess the safety of the superoxide dismutase mimetic GC4419 in combination with radiation and concurrent cisplatin for patients with oral cavity or oropharyngeal cancer (OCC) and to assess the potential of GC4419 to reduce severe oral mucositis (OM).

PATIENTS AND METHODS: Patients with locally advanced OCC treated with definitive or postoperative intensity modulated radiation therapy (IMRT) plus cisplatin received GC4419 by 60-minute intravenous infusion, ending <60 minutes before IMRT, Monday through Friday for 3 to 7 weeks, in a dose and duration escalation study. Oral mucositis was assessed twice weekly during and weekly after IMRT.

RESULTS: A total of 46 patients received GC4419 in 11 separate dosing and duration cohorts: dose escalation occurred in 5 cohorts receiving 15 to 112 mg/d over 3 weeks (n=20), duration escalation in …

Visual Scanning Of Males And Females In Infancy, Hannah B. White, Alyson J. Hock, Rachel L. Jubran, Alison Heck, Ramesh S. Bhatt

Psychology Faculty Publications

This study addressed the development of attention to information that is socially relevant to adults by examining infants' (n = 64) scanning patterns of male and female bodies. Infants exhibited systematic attention to regions associated with sex-related scanning by adults, with 3.5-and 6.5-month-olds looking longer at the torso of females than males and longer at the legs of males than females. However, this pattern of looking was not found when infants were tested on headless bodies in Experiment 2, which suggests that infants' differential gaze pattern in Experiment 1 was not due to low-level stimulus features, such as clothing, and …

Development Of Body Emotion Perception In Infancy: From Discrimination To Recognition, Alison Heck, Alyson Chroust, Hannah B. White, Rachel Lynn Jubran, Ramesh S. Bhatt

Psychology Faculty Publications

Research suggests that infants progress from discrimination to recognition of emotions in faces during the first half year of life. It is unknown whether the perception of emotions from bodies develops in a similar manner. In the current study, when presented with happy and angry body videos and voices, 5-month-olds looked longer at the matching video when they were presented upright but not when they were inverted. In contrast, 3.5-month-olds failed to match even with upright videos. Thus, 5-month-olds but not 3.5-month-olds exhibited evidence of recognition of emotions from bodies by demonstrating intermodal matching. In a subsequent experiment, younger infants …

Use Of Self-Management Interventions For Chronic Pain Management: A Comparison Between Rural And Nonrural Residents, Linda H Eaton, Dale J Langford, Alexa R Meins, Tessa Rue, David J Tauben, Ardith Z Doorenbos

Project ECHO Bibliography

Individuals with chronic pain who live in rural communities often lack access to pain specialists and rely on primary care providers who may be less prepared. Research has indicated that rural residents with chronic pain are more likely to receive an opioid prescription than nonrural residents. Although self-management approaches are available for chronic pain management, it is unclear to what extent rural residents use these interventions. This study compares usage of self-management interventions and opioid-based analgesics for chronic pain management between rural and nonrural residents. This study is a secondary analysis of baseline data from a randomized controlled trial evaluating …

Reassessing The Duration Of The Second Stage Of Labor In Relation To Maternal And Neonatal Morbidity., Katherine L. Grantz, Rajeshwari Sundaram, Ling Ma, Stefanie Hinkle, Vincenzo Berghella, Matthew K. Hoffman, Uma M. Reddy

Department of Obstetrics and Gynecology Faculty Papers

OBJECTIVE: To assess the morbidity associated with continuing the second-stage duration of labor, weighing the probability of spontaneous vaginal birth without morbidity compared with birth with serious maternal or neonatal complications.

METHODS: In a retrospective cohort, we analyzed singleton, vertex births at 36 weeks of gestation or greater without prior cesarean delivery (n=43,810 nulliparous and 59,605 multiparous women). We calculated rates of spontaneous vaginal birth and composite serious maternal or neonatal complications. Results were stratified by parity (nulliparous or multiparous) and epidural status (yes or no). Competing risks models were created for 1) spontaneous vaginal birth with no morbidity, 2) …

Symptomatic Celiomesenteric Trunk: Variable Presentations And Outcomes In 2 Patients, Michael L Kueht, Darrel L Wu, Joseph L Mills, Ramyar Gilani

The Texas Heart Institute Journal

Mesenteric ischemia can be difficult to diagnose without a high degree of suspicion because it presents in a variety of ways. Visceral vascular collaterals between the fore- and midgut often provide protection against ischemia; however, the presence of anatomic variations, such as celiomesenteric trunk, can undermine the expected redundancy. Misdiagnosis can result in prolonged suffering or death, as evidenced in 2 of our patients with celiomesenteric trunk. The first patient with chronic mesenteric ischemia was diagnosed in the clinic and underwent successful surgical correction; the other had overwhelming, acute mesenteric ischemia, which resulted in death. Our cases show that successful …

Cardiac Rehabilitation Improves Cardiometabolic Health In Young Patients With Nonischemic Dilated Cardiomyopathy, Samuel G Wittekind, Yvette Gerdes, Wayne Mays, Clifford Chin, John L Jefferies

The Texas Heart Institute Journal

Nonischemic dilated cardiomyopathy is deadly and costly, and treatment options are limited. Cardiac rehabilitation has proved safe and beneficial for adults with various types of heart failure. Therefore, we retrospectively evaluated the hypothesis that rehabilitation is safe and improves cardiometabolic health in young patients with nonischemic dilated cardiomypathy. From 2011 through 2015, 8 patients (4 males) (mean age, 20.6 ± 6.6 yr; range, 10-31 yr) underwent rehabilitation at our institution. They were in American Heart Association class C or D heart failure and were on maximal medical therapy. Their mean left ventricular ejection fraction at baseline was 0.26 ± 0.15. …

Novel Scoring System For Prediction Of Cardiac Syndrome X In Women With Typical Angina And A Positive Exercise Tolerance Test, Farzad Masoudkabir, Ali Vasheghani-Farahani, Elham Hakki, Hamidreza Poorhosseini, Saeed Sadeghian, Seyed Hesameddin Abbasi, Shahram Bahmanyar, Seyed Ebrahim Kassaian

The Texas Heart Institute Journal

A major diagnostic challenge for cardiologists is to distinguish cardiac syndrome X (CSX) from obstructive coronary artery disease in women with typical angina and a positive exercise tolerance test (ETT). We performed this study to develop a scoring system that more accurately predicts CSX in this patient population.

Data on 976 women with typical angina and a positive ETT who underwent coronary angiography at our center were randomly divided into derivation and validation datasets. We developed a backward stepwise logistic regression model that predicted the presence of CSX, and a scoring system was derived from it.

The derivation dataset (809 …

Effects Of Older Donor Age And Cold Ischemic Time On Long-Term Outcomes Of Heart Transplantation, Heidi J Reich, Jon A Kobashigawa, Tamar Aintablian, Danny Ramzy, Michelle M Kittleson, Fardad Esmailian

The Texas Heart Institute Journal

Using older donor hearts in cardiac transplantation may lead to inferior outcomes: older donors have more comorbidities that reduce graft quality, including coronary artery disease, hypertension, diabetes mellitus, and dyslipidemia. Shorter cold ischemic times might overcome the detrimental effect of older donor age. We examined the relationship between donor allograft age and cold ischemic time on the long-term outcomes of heart transplant recipients. rom 1994 through 2010, surgeons at our hospital performed 745 heart transplantations. We retrospectively classified these cases by donor ages of(younger) and ≥50 years (older), then by cold ischemic times of(short), 120 to 240 min (intermediate), and …

The literature was searched using PubMed, EMBASE, Scopus, CINAHL, Cochrane Library, and ProQuest Dissertations & Theses Global databases (inception to December 2017) by two independent review authors. Inclusion criteria included articles which evaluated the prevalence …

Birth Weight And Body Mass Index Z-Score In Childhood Brain Tumors: A Cross-Sectional Study, Kuan-Wen Wang, Russell J De Souza, Adam Fleming, Donna L Johnston, Shayna M Zelcer, Shahrad Rod Rassekh, Sarah Burrow, Lehana Thabane, M Constantine Samaan

Paediatrics Publications

Children with brain tumors (CBT) are at higher risk of cardiovascular disease and type 2 diabetes compared to the general population, in which birth weight is a risk factor for these diseases. However, this is not known in CBT. The primary aim of this study was to explore the association between birth weight and body mass measures in CBT, compared to non-cancer controls. This is a secondary data analysis using cross-sectional data from the CanDECIDE study (n = 78 CBT and n = 133 non-cancer controls). Age, sex, and birth weight (grams) were self-reported, and confirmed through examination of the …

Kruppel-Like Factor 4-Dependent Staufen1-Mediated Mrna Decay Regulates Cortical Neurogenesis, Byoung-San Moon, Jinlun Bai, Mingyang Cai, Chunming Liu, Jiandang Shi, Wange Lu

Molecular and Cellular Biochemistry Faculty Publications

Kruppel-like factor 4 (Klf4) is a zinc-finger-containing protein that plays a critical role in diverse cellular physiology. While most of these functions attribute to its role as a transcription factor, it is postulated that Klf4 may play a role other than transcriptional regulation. Here we demonstrate that Klf4 loss in neural progenitor cells (NPCs) leads to increased neurogenesis and reduced self-renewal in mice. In addition, Klf4 interacts with RNA-binding protein Staufen1 (Stau1) and RNA helicase Ddx5/17. They function together as a complex to maintain NPC self-renewal. We report that Klf4 promotes Stau1 recruitment to the 3′-untranslated region of neurogenesis-associated mRNAs, …

Objective Coding Of Content And Techniques In Workplace-Based Supervision Of An Ebt In Public Mental Health, Shannon Dorsey, Suzanne E U Kerns, Leah Lucid, Michael D Pullmann, Julie P Harrison, Lucy Berliner, Kelly Thompson, Esther Deblinger

Rowan-Virtua School of Osteopathic Medicine Departmental Research

BACKGROUND: Workplace-based clinical supervision as an implementation strategy to support evidence-based treatment (EBT) in public mental health has received limited research attention. A commonly provided infrastructure support, it may offer a relatively cost-neutral implementation strategy for organizations. However, research has not objectively examined workplace-based supervision of EBT and specifically how it might differ from EBT supervision provided in efficacy and effectiveness trials.

METHODS: Data come from a descriptive study of supervision in the context of a state-funded EBT implementation effort. Verbal interactions from audio recordings of 438 supervision sessions between 28 supervisors and 70 clinicians from 17 public mental health …

Early Procedural Pain Is Associated With Regionally-Specific Alterations In Thalamic Development In Preterm Neonates., Emma G Duerden, Ruth E Grunau, Ting Guo, Justin Foong, Alexander Pearson, Stephanie Au-Young, Raphael Lavoie, M Mallar Chakravarty, Vann Chau, Anne Synnes, Steven P Miller

Brain and Mind Institute Researchers' Publications

Very preterm human neonates are exposed to numerous invasive procedures as part of life-saving care. Evidence suggests that repetitive neonatal procedural pain precedes long-term alterations in brain development. However, to date the link between pain and brain development has limited temporal and anatomic specificity. We hypothesized that early exposure to painful stimuli during a period of rapid brain development, before pain modulatory systems reach maturity, will predict pronounced changes in thalamic development, and thereby cognitive and motor function. In a prospective cohort study, 155 very preterm neonates (82 males, 73 females) born 24-32 weeks' gestation underwent two MRIs at median …

The glutamatergic neurotransmitter system may play an important role in attention-deficit hyperactivity disorder (ADHD). This 5-week, open-label, single-blind, placebo-controlled study reports the safety, pharmacokinetics and responsiveness of the metabotropic glutamate receptor (mGluR) activator fasoracetam (NFC-1), in 30 adolescents, age 12-17 years with ADHD, harboring mutations in mGluR network genes. Mutation status was double-blinded. A single-dose pharmacokinetic profiling from 50-800 mg was followed by a single-blind placebo at week 1 and subsequent symptom-driven dose advancement up to 400 mg BID for 4 weeks. NFC-1 treatment resulted in significant improvement. Mean Clinical Global Impressions-Improvement (CGI-I) and Severity (CGI-S) scores were, respectively, 3.79 …
