System Reliability Analysis Of The Scoliosis Disorder., Fatemeh Nouri, Seyed Hooman Ghasemi, Ji Yun Lee

Henry M. Rowan College of Engineering Departmental Research

BACKGROUND: Scoliosis is a spine abnormal deviation, which is an idiopathic disorder among children and adolescents. As a matter of the fact, distribution of loads on the patient's spine and load-carrying capacity of the vertebral column are both random variables. Therefore, the probabilistic approach may consider as a sophisticated method to deal with this problem.

METHOD: Reliability analysis is a probabilistic-based approach to consider the uncertainties of load and resistance of the vertebral column. The main contribution of this paper is to compare the reliability level of a normal and scoliosis spinal. To do so, the numerical analyses associated with …

Nr2f1 Heterozygous Knockout Mice Recapitulate Neurological Phenotypes Of Bosch-Boonstra-Schaaf Optic Atrophy Syndrome And Show Impaired Hippocampal Synaptic Plasticity, Chun-An Chen, Wei Wang, Steen E Pedersen, Ayush Raman, Michelle L Seymour, Fernanda R Ruiz, Anping Xia, Meike E Van Der Heijden, Li Wang, Jiani Yin, Joanna Lopez, Megan E Rech, Richard A Lewis, Samuel M Wu, Zhandong Liu, Fred A Pereira, Robia G Pautler, Huda Y Zoghbi, Christian P Schaaf

Faculty, Staff and Students Publications

Bosch-Boonstra-Schaaf optic atrophy syndrome (BBSOAS) has been identified as an autosomal-dominant disorder characterized by a complex neurological phenotype, with high prevalence of intellectual disability and optic nerve atrophy/hypoplasia. The syndrome is caused by loss-of-function mutations in NR2F1, which encodes a highly conserved nuclear receptor that serves as a transcriptional regulator. Previous investigations to understand the protein's role in neurodevelopment have mostly used mouse models with constitutive and tissue-specific homozygous knockout of Nr2f1. In order to represent the human disease more accurately, which is caused by heterozygous NR2F1 mutations, we investigated a heterozygous knockout mouse model and found that this model …

Associations Of Maternal Resources With Care Behaviours Differ By Resource And Behaviour, Sulochana Basnet, Edward A. Frongillo Jr., Phuong Hong Nguyen, Spencer Moore, Mandana Arabi

Faculty Publications

Care is important for children's growth and development, but lack or inadequacy of resources for care can constrain appropriate caregiving. The objectives of this study were to examine whether maternal resources for care are associated with care behaviours specifically infant and young child feeding, hygiene, health-seeking, and family care behaviours. The study also examined if some resources for care are more important than others. This study used baseline Alive & Thrive household surveys from Bangladesh, Vietnam, and Ethiopia. Measures of resources for care were maternal education, knowledge, height, nourishment, mental well-being, decision-making autonomy, employment, support in chores, and perceived instrumental …

Public Social Media Consultations For Dermatologic Conditions: An Online Survey, Elizabeth Schoenberg, Doaa Shalabi, Jordan Wang, Nazanin Saedi, Matthew Keller

Department of Dermatology and Cutaneous Biology Faculty Papers

The use of social media in medicine has been increasingly studied in recent years, especially concerning its role in patient outreach, education, diagnosis, and management. Dermatology is a unique field in that patients can post photographs of their skin ailments when seeking online medical advice and information. This study examines the role of public social media consultations for dermatologic conditions. A large portion of patients utilize social media for dermatologic consultations and many do not seek care from a dermatologist afterward. Future studies should trend this phenomenon, especially as the use of social media continues to expand.

Error-Corrected Sequencing Strategies Enable Comprehensive Detection Of Leukemic Mutations Relevant For Diagnosis And Minimal Residual Disease Monitoring, Erin L Crowgey, Nitin Mahajan, Wing Hing Wong, Anilkumar Gopalakrishnapillai, Sonali P Barwe, E Anders Kolb, Todd E Druley

2020-Current year OA Pubs

BACKGROUND: Pediatric leukemias have a diverse genomic landscape associated with complex structural variants, including gene fusions, insertions and deletions, and single nucleotide variants. Routine karyotype and fluorescence in situ hybridization (FISH) techniques lack sensitivity for smaller genomic alternations. Next-generation sequencing (NGS) assays are being increasingly utilized for assessment of these various lesions. However, standard NGS lacks quantitative sensitivity for minimal residual disease (MRD) surveillance due to an inherently high error rate.

METHODS: Primary bone marrow samples from pediatric leukemia (n = 32) and adult leukemia subjects (n = 5), cell line MV4-11, and an umbilical cord sample were utilized for …

Frontal Volume As A Potential Source Of The Comorbidity Between Attention-Deficit/Hyperactivity Disorder And Reading Disorders., Michelle Y Kibby, Sarah M Dyer, Sylvia E Lee, Maria Stacy

Publications

Prefrontal volume reductions commonly are demonstrated in ADHD, but the literature examining prefrontal volume in reading disorders (RD) is scant despite their also having executive functioning (EF) deficits. Furthermore, only a few anatomical studies have examined the frontal lobes in comorbid RD/ADHD, though they have EF deficits similar to RD and ADHD. Hence, we examined frontal gyri volume in children with RD, ADHD, RD/ADHD and controls, as well as their relationship to EF for gyri found to differ between groups. We found right inferior frontal (RIF) volume was smaller in ADHD, and smaller volume was related to worse behavioral regulation. …

Lymphatic filariasis has remained endemic in Fiji despite repeated mass drug administration using the well-established and safe combination of diethylcarbamazine and albendazole (DA) since 2002. In certain settings the addition of ivermectin to this combination (IDA) remains a safe strategy and is more efficacious. However, the safety has yet to be described in scabies and soil-transmitted helminth endemic settings like Fiji. Villages of Rotuma and Gau islands were randomised to either DA or IDA. Residents received weight-based treatment unblinded with standard exclusions. Participants were actively found and asked by a nurse about their health daily for the first two days …

Faculty, Staff and Student Publications

BACKGROUND: This study investigated the relationship between smoking and hearing loss and deafness (HLD) and whether the relationship is modified by genetic variation. Data for these analyses was from the subset of Japanese American families collected as part of the American Diabetes Association Genetics of Non-insulin Dependent Diabetes Mellitus study. Logistic regression with generalized estimating equations assessed the relationship between HLD and smoking. Nonparametric linkage analysis identified genetic regions harboring HLD susceptibility genes and ordered subset analysis was used to identify regions showing evidence for gene-smoking interactions. Genetic variants within these candidate regions were then each tested for interaction with …

Examining Measurement Reactivity In Daily Diary Data On Substance Use: Results From A Randomized Experiment, Anne Buu, Songshan Yang, Runze Li, Marc A Zimmerman, Rebecca M Cunningham, Maureen A Walton

Faculty, Staff and Student Publications

The debate about whether measurement reactivity exists in daily diary research on substance use is still unsettled due to the issues of study design and statistical methodology. This study proposes a time-varying effect model (TVEM) that characterizes the trajectory of substance use behaviors with nonparametric functions determined by the data rather than imposes presumed parametric functions. It also allows researchers to investigate the effect of measurement reactivity on not only the likelihood of using substances but also the amount of substance use. The TVEM was applied to analyze diary data on alcohol and marijuana use collected from an experiment, which …

Orthostatic Hypotension, Cardiovascular Outcomes, And Adverse Events: Results From Sprint, Stephen P Juraschek, Addison A Taylor, Jackson T Wright, Gregory W Evans, Edgar R Miller, Timothy B Plante, William C Cushman, Tanya R Gure, William E Haley, Imran Moinuddin, John Nord, Suzanne Oparil, Carolyn Pedley, Christianne L Roumie, Jeff Whittle, Alan Wiggers, Ciarán Finucane, Rose Anne Kenny, Lawrence J Appel, Raymond R Townsend

Orthostatic hypotension (OH) is frequently observed with hypertension treatment, but its contribution to adverse outcomes is unknown. The Systolic Blood Pressure Intervention Trial (SPRINT) was a randomized trial of adults, age ≥50years at high risk for cardiovascular disease (CVD) with a seated systolic BP (SBP) of 130–180 mmHg and a standing SBP ≥110 mmHg. Participants were randomized to a SBP treatment goal of either <120 mmHg or <140 mmHg. OH was defined as a drop in SBP≥20 or diastolic BP ≥10 mmHg one minute after standing from a seated position. We used Cox models to examine the association of OH with CVD or adverse study events by randomized BP goal. During the follow-up period (median 3years), there were 1,170 (5.7%) instances of OH among those assigned a standard BP goal, and 1,057 (5.0%) among those assigned the intensive BP goal. OH was not associated with higher risk of CVD events (primary outcome: HR 1.06; 95%CI: 0.78,1.44). Moreover, OH was not associated with syncope, electrolyte abnormalities, injurious falls, or acute renal failure. OH was associated with hypotension-related hospitalizations or emergency department visits (HR 1.77; 1.11,2.82) and bradycardia (HR 1.94; 1.19,3.15), but these associations did not differ by BP treatment goal. OH was not associated with a higher risk of CVD events and BP treatment goal had no effect on OH’s association with hypotension and bradycardia. Symptomless OH during hypertension treatment should not be viewed as a reason to down-titrate therapy even in the setting of a lower BP goal.

Fibrin Clots Maintain The Viability And Proliferative Capacity Of Human Mesenchymal Stem Cells: An In Vitro Study, Ryan J Warth, Paul G Shupe, Xueqin Gao, Mohammad Syed, Walter R Lowe, Johnny Huard, Christopher D Harner

Faculty, Staff and Student Publications

BACKGROUND: Augmentation of soft-tissue repairs with an autologous fibrin clot has been used clinically for nearly four decades; however, fibrin clots tend to produce an abundance of scar tissue, which is known to inhibit soft-tissue regeneration. Mesenchymal stem cells (MSCs) embedded in fibrin clots before repair could reduce scar tissue deposition and facilitate soft-tissue regeneration. To our knowledge, no published studies have directly evaluated the viability or bioactivity of MSCs in fresh human fibrin clots over time. The purpose of this study was to evaluate the viability and bioactivity of human MSCs inside human fibrin clots over time in nutritive …

The Impact Of Diabetic Foot Ulcers And Unilateral Offloading Footwear On Gait In People With Diabetes, Erica Ling, Brian Lepow, He Zhou, Ana Enriquez, Ashley Mullen, Bijan Najafi

Faculty, Staff and Students Publications

BACKGROUND: Unilateral offloading footwear prescribed to patients with diabetic foot ulcers elevates one limb relative to the other, which may lead to limp and abnormal gait. This study investigated whether the unilateral foot ulcer and offloading combination negatively impacts gait function beyond diabetic peripheral neuropathy.

METHODS: Eighty-six participants were recruited in 3 groups: 12 with diabetic peripheral neuropathy and unilateral foot ulcers wearing offloading footwear (offloading group, age = 55.6 ± 9.5 years, BMI = 30.9 ± 4.5 kg/m

FINDINGS: The offloading group exhibited deteriorated gait function compared to the non-diabetic group (p < 0.005, Cohen's effect size d = 0.90-2.61). They also had decreased gait speed (p < 0.001, d = 1.79) and stride length (p < 0.001, d = 1.76), as well as increased gait cycle time (p < 0.001, d = 1.67) and limp (p < 0.050, d = 0.72-1.49) compared to the neuropathy group. The offloading group showed increased gait unsteadiness compared to the neuropathy group, but the difference did not reach statistical significance in our samples.

INTERPRETATION: This study demonstrated that while diabetic …

We have encountered pancreatic tumors with unique histologic features, which do not conform to any of the known tumors of the pancreas or other anatomical sites. We aimed to define their clinicopathologic features and whether they are characterized by recurrent molecular signatures. Eight cases were identified; studied histologically and by immunohistochemistry. Selected cases were also subjected to whole-exome sequencing (WES; n = 4), RNA-sequencing (n = 6), Archer FusionPlex assay (n = 5), methylation profiling using the Illumina MethylationEPIC (850k) array platform (n = 6), and TERT promoter sequencing (n = 5). Six neoplasms occurred in females. The mean age …

Staged Laser Interstitial Thermal Therapy (Litt) Treatments To Left Insular Low-Grade Glioma, Daniel M. Hafez, Caroline Liekweg, Eric C. Leuthardt

2020-Current year OA Pubs

BACKGROUND AND IMPORTANCE: Low-grade insular gliomas remain challenging tumors for aggressive resection because of the numerous functional and vascular structures surrounding them. Because of the potential morbidities associated with open surgical resection, less invasive techniques may confer a more optimal balance between cytoreduction and surgical complications. For this reason, we evaluated the use of laser interstitial thermal therapy (LITT) for resection of a dominant hemisphere oligodendroglioma World Health Organization (WHO) grade II in a 68-yr-old patient by use of multiple staged surgeries for its resection.

CLINICAL PRESENTATION: Patient KK was a 68-yr-old female who was found to have a large, …

Head motion represents one of the greatest technical obstacles in magnetic resonance imaging (MRI) of the human brain. Accurate detection of artifacts induced by head motion requires precise estimation of movement. However, head motion estimates may be corrupted by artifacts due to magnetic main field fluctuations generated by body motion. In the current report, we examine head motion estimation in multiband resting state functional connectivity MRI (rs-fcMRI) data from the Adolescent Brain and Cognitive Development (ABCD) Study and comparison 'single-shot' datasets. We show that respirations contaminate movement estimates in functional MRI and that respiration generates apparent head motion not associated …

Mcgaghie, Kristin L. Rising

Department of Pharmacology and Experimental Therapeutics Faculty Papers

BACKGROUND: Diagnostic uncertainty occurs frequently in emergency medical care, with more than one-third of patients leaving the emergency department (ED) without a clear diagnosis. Despite this frequency, ED providers are not adequately trained on how to discuss diagnostic uncertainty with these patients, who often leave the ED confused and concerned. To address this training need, we developed the Uncertainty Communication Education Module (UCEM) to teach physicians how to discuss diagnostic uncertainty. The purpose of the study is to evaluate the effectiveness of the UCEM in improving physician communications.

METHODS: The trial is a multicenter, two-arm randomized controlled trial designed to …

Open Access Publications

BACKGROUND: Childhood undernutrition remains a significant global health challenge accounting for over half of all under 5 child mortality. Moderate acute malnutrition (MAM), which leads to wasting [weight-for-length z-scores (WLZ) between - 2 and - 3], affects 33 million children under 5 globally and more than 2 million in Bangladesh alone. We have previously reported that acute malnutrition in this population is associated with gut microbiota immaturity, and in a small, 1-month pre-proof-of-concept (POC) study demonstrated that a microbiota-directed complementary food formulation (MDCF-2) was able to repair this immaturity, promote weight gain and increase plasma biomarkers and mediators of healthy …

BACKGROUND: Acute flaccid myelitis (AFM) is a severe illness similar to paralytic poliomyelitis. It is unclear how frequently AFM occurred in U.S. children after poliovirus elimination. In 2014, an AFM cluster was identified in Colorado, prompting passive US surveillance that yielded 120 AFM cases of unconfirmed etiology. Subsequently, increased reports were received in 2016 and 2018. To help inform investigations on causality of the recent AFM outbreaks, our objective was to determine how frequently AFM had occurred before 2014, and if 2014 cases had different characteristics.

METHODS: We conducted a retrospective study covering 2005-2014 at 5 pediatric centers in 3 …
