miR-486 is a muscle-enriched microRNA, or “myomiR,” that has reduced expression correlated with Duchenne muscular dystrophy (DMD). To determine the function of miR-486 in normal and dystrophin-deficient muscles and elucidate miR-486 target transcripts in skeletal muscle, we characterized mir-486 knockout mice (mir-486 KO). mir-486 KO mice developed disrupted myofiber architecture, decreased myofiber size, decreased locomotor activity, increased cardiac fibrosis, and metabolic defects were exacerbated in mir-486 KO:mdx5cv (DKO) mice. To identify direct in vivo miR-486 muscle target transcripts, we integrated RNA sequencing and chimeric miRNA eCLIP sequencing to identify key transcripts and pathways that contribute towards mir-486 …

Faculty, Staff and Student Publications

BACKGROUND: Evidence for effective pain management and opioid minimization of intravenous ketamine in elective surgery has been extrapolated to acutely injured patients, despite limited supporting evidence in this population. This trial seeks to determine the effectiveness of the addition of sub-dissociative ketamine to a pill-based, opioid-minimizing multi-modal pain regimen (MMPR) for post traumatic pain.

METHODS: This is a single-center, parallel-group, randomized, controlled comparative effectiveness trial comparing a MMPR to a MMPR plus a sub-dissociative ketamine infusion. All trauma patients 16 years and older admitted following a trauma which require intermediate (IMU) or intensive care unit (ICU) level of care are …

Duchenne muscular dystrophy (DMD) is an X-linked recessive disease characterized by skeletal muscle instability, progressive muscle wasting, and fibrosis. A major driver of DMD pathology stems from aberrant upregulation of transforming growth factor β (TGFβ) signaling. In this report, we investigated the major transducers of TGFβ signaling, i.e., receptor Smads (R-Smads), in DMD patient skeletal muscle and observed a 48-fold increase in Smad8 mRNA. Smad1, Smad2, Smad3, and Smad5 mRNA were only minimally increased. A similar pattern was observed in the muscle from the mdx5cv mouse. Western blot analysis showed upregulation of phosphorylated Smad1, Smad5, and Smad8 …

Mice Lacking Wnt9a Or Wnt4 Are Prone To Develop Spontaneous Osteoarthritis With Age And Display Alteration In Either The Trabecular Or Cortical Bone Compartment, Stefan Teufel, Lena Wolff, Ulrich König, Akio Kobayashi, Richard Behringer, Christine Hartmann

Faculty, Staff and Student Publications

Osteoarthritis (OA) is a common degenerative disease of the joint, with a complex multifactorial not yet fully understood etiology. Over the past years, the Wnt signaling pathway has been implicated in osteoarthritis. In a recent genomewide association study (GWAS), the chromosomal location on chromosome 1, linked to the Wnt3a-Wnt9a gene locus, was identified as the most significant locus associated with a thumb osteoarthritis endophenotype. Previously, it was shown that WNT9a is involved in maintaining synovial cell identity in the elbow joint during embryogenesis. Here, we report that the conditional loss of Wnt9a in the Prx1-Cre expressing limb mesenchyme or Prg4-CreER …

Corticosteroid Injection Exhibits Symptomatic Improvement In Cts Patients With Negative Emgs, Brooke G. Garnica, Aaron R. Prater, Elizabeth A. Washnock-Schmid, Alaa Hazime, Dr. Charles S. Day

Medical Student Research Symposium

Introduction

While corticosteroid injections for carpal tunnel syndrome (CTS) are effective in patients with mild EMGs, no literature has examined the effectiveness of injections in patients with negative EMGs. We hypothesized that patients with negative EMGs will have minimal symptomatic and functional improvement.

Methods

The Boston Carpal Tunnel Questionnaire (BCTQ) was administered to patients clinically diagnosed with CTS and a negative or mild EMG prior to corticosteroid injection. The BCTQ comprises functional (FSS) and symptom status (SSS) questions. The patient was re-evaluated at 2-weeks, 1-, 3-, and 6-months post-injection. Data were analyzed via one-way ANOVA tests. A post-hoc Benjamini-Hochberg FDR …

The Effects Of Vitamin D Supplementation On Athletic Performance And Injury Prevention, Amani Adeeb Abushamma

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Vitamin D supplementation has numerous effects on athletic performance and plays a significant role in preventing an athlete’s risk of getting injuries. Vitamin D has an impact on numerous physiological functions such as: bone health, muscle function, inflammatory response, and immune function. An athlete’s bone and muscle health are essential for maximum performance and career success. A bone fracture due to vitamin D deficiency can delay an athlete’s training and ultimately inhibit obtaining a collegiate scholarship and/or contract. A cross sectional study found that more than half of athletic trainers did not view 25-hydroxyvitamin D(25[OH]) testing and vitamin D supplementation …

Feasibility And Efficacy Of Bisphosphonate Use For The Prevention Of Bone And Muscle Loss, Laura E. Flores

Theses & Dissertations

Loss of bone and muscle mass often occurs in tandem, increasing the risk of fragility fractures. Whereas many drugs are approved for the treatment of bone loss, there are few treatments available for the concomitant loss of bone and muscle. Identification of a treatment to mitigate pathologic bone and muscle atrophy has the potential to impact countless populations and influence approaches for healthy aging. Bisphosphonates have emerged as a potential treatment for both bone and muscle loss in cellular, murine, and observational human studies. Our findings of modest weight maintenance in postmenopausal women treated with 12-months of risedronate, relative to …

Objectives/Goal: Examine variation in initial lab testing & imaging obtained in patients hospitalized for common MSKIs and explore association with clinical outcomes (length of stay (LOS), cost, 30-day readmission).

Methods/Design: We performed a retrospective, multicenter cohort study of hospitalized children aged 6 months to 18 years with a …

Latarjet Surgery Leads To Decreased Rates Of Subjective Instability Compared To Bankart Repair With Concomitant Remplissage, Joshua Spada, Ryan W. Paul, Manoj Reddy, Gabriel Onor, John Hayden Sonnier, Ari Clements, Meghan E. Bishop, Brandon J. Erickson

Rowan-Virtua Research Day

Background: Predictive factors for performing remplissage concomitantly with arthroscopic Bankart repair include the presence of humeral or glenoid defects >11% and/or revision surgery. International and societal consensus statements support these findings, as surgeons recommend the Latarjet procedure for patients with significant glenoid bone loss (>15-20%) while remplissage is recommended for patients with off-track or engaging Hill-Sachs lesions without significant glenoid bone loss. While several studies have compared outcomes between Latarjet surgery and remplissage, these studies have only evaluated patients with engaging Hill-Sachs lesions, not consecutive patient cohorts indicated for each surgery.

Purpose: To compare rates of recurrent instability, re-operation, …

Exploring The Viability Of A Microglia Attenuating Treatment Model For Fibromyalgia Patients, Rohan Yarlagadda

Rowan-Virtua Research Day

Fibromyalgia refers to a rheumatic condition experienced as pain all over the body without a specific cause. This is considered a diagnosis of exclusion. This classification seems to suggest that any treatment options for it are purely symptomatic and are not disease targeted. Its complex diagnosis and underlying pathology contribute to the challenge of medically addressing fibromyalgia. Without a strict cause, fibromyalgia is often treated symptomatically with CBT and SNRIs. However, recent research suggests that existing therapeutic approaches are not very effective, especially when considering long term benefits for this chronic condition. This beckons for novel treatment options for these …

Rowan-Virtua Research Day

New Jersey was placed in a state of emergency and a statewide stay-at-home order during the COVID-19 pandemic

Very little has been published examining the effects of chronic pain after stopping osteopathic manipulative medicine (OMM), although it seems unethical to stop a treatment shown to work so well that is both minimally invasive and cost effective

We hypothesized OMM patients experienced an increase in pain since the onset of COVID-19 pandemic and closure of OMM/Family Medicine offices

Use Of Osteopathic Manipulative Treatment In Alleviating Hypertonic Chest Wall Pain, David Ho, James Espinosa, Alan Lucerna

Rowan-Virtua Research Day

We present the case of a 20-year-old male patient with no cardiac history coming in for left sided chest pain described as “burning” sensation. On physical exam, it was noted that patient had hypertonic chest wall muscles that were tight and spastic when palpated on the left chest wall. We used Osteopathic Manipulative Treatment (OMT) to help patient relieve hypertonic muscle. We chose to use muscle energy technique (MET) since this relies on reciprocal inhibition with the end result being relaxation of the target muscle.

The patient had resolution of chest pain after applying the technique. Although we did not …

Does Prehabilitation Prior To Ulnar Collateral Ligament Surgery Affect Return To Sport Rate Or Time In Baseball Players With Partial Ucl Tears?, Joshua Spada, Kourtney Snigar, Ryan W. Paul, Usman Zareef, Anya Hall, Brandon J. Erickson, Michael G. Ciccotti, Stephen J. Thomas

Rowan-Virtua Research Day

Those who suffer a partial thickness ulnar collateral ligament (UCL) tear often undergo a period of nonoperative management including physical therapy rehabilitation. This treatment is aimed at optimizing range of motion (ROM) and strengthening the supporting structures around the elbow to help offload the UCL.

Unfortunately, some of these patients fail nonoperative management and require surgical intervention. This creates a unique set of patients who essentially underwent “prehabilitation” prior to their UCL surgery. Prehabilitation is considered a period of structured physical therapy rehabilitation aimed at strengthening structures surrounding an injured tendon or ligament, to allow for dissipation of stress away …

Radiographic axial spondyloarthritis axSpA ) or typical ankylosing spondyloarthritis (AS) is a classification of axial spondyloarthritis with the classic radiographic features of sacroiliitis. Axial spondyloarthritis is a disabling spondyloarthropathy of the spine that presents with chronic back pain usually before the age of 45. It may be associated with extraspinal features including dactylitis , synovitis, and enthesitis in addition to other nonarticular signs. Chronic back pain is one of the most common presenting symptoms for AS , but frequently there is a 5-7 year delay between the onset of symptoms and diagnosis of the disease . A standard AP plain …

Omm As A Complementary Therapy For Chronic Shoulder Overuse Injury In A Division Iii Softball Pitcher, Drew Saltzman, Ruchir Nanavati, Taylor Parsons, Seungkyu Park, David Abend

Rowan-Virtua Research Day

At the height of the season, baseball and softball pitchers are playing 4-5 games a week and practicing on days without games. As a result, they put tremendous additive stress on their throwing shoulder and elbow joint.

This case utilized a novel, non-invasive osteopathic approach to improving shoulder mobility in a Division III athlete. If used on a regular basis, the shoulder mobility technique shows utility for athletes suffering from overuse injury. Our patient showed mild qualitative improvement, however they continue to use OMM as complementary treatment and describe a moderate qualitative improvement.

When Problems Become Solutions: Harnessing The Osteogenic Capacity Of Disease-Causing Stem Cells To Repair Bone Fractures, Mehreen Pasha

University Scholar Projects

While we often perceive disease as negative, there is potential to engineer seemingly negative biological phenomena into therapeutics to treat a variety of human illnesses. Fibrodysplasia ossificans progressiva (FOP) is a genetic disorder involving uncontrolled, widespread, extraskeletal bone growth, or heterotopic ossification (HO). In FOP patients, stem cells called fibro/adipogenic progenitors (FAPs) follow an abnormal, osteogenic pathway. In the present study, we investigate whether we can adapt these Acvr1 mutant FAPs, which are exceptional at producing bone, to repair bone fractures in otherwise normal patients. The primary aims of this study are (1) to devise and optimize a novel method …

Therapeutics targeting osteoclasts are commonly used treatments for bone metastasis; however, whether and how osteoclasts regulate premetastatic niche and bone tropism are largely unknown. In this study, we report that osteoclast precursors (OPs) can function as a premetastatic niche component that facilitates breast cancer (BCa) bone metastasis at early stages. At the molecular level, unbiased GPCR ligand/agonist screening in BCa cells suggested that R-spondin 2 (RSPO2) and RANKL, through interaction with their receptor LGR4, promoted osteoclastic premetastatic niche formation and enhanced BCa bone metastasis. This was achieved by RSPO2/RANKL-LGR4 signal modulating the WNT inhibitor DKK1 through Gαq and β-catenin signaling. …

Investigating The Role Of The Skeletal Muscle In Amyotrophic Lateral Sclerosis Neuromuscular Junction Dysfunction, Agnes Badu-Mensah

Electronic Theses and Dissertations, 2020-2023

Neuromuscular junction (NMJ) dysfunction has been identified as one of the earliest events in Amyotrophic Lateral Sclerosis (ALS) pathology. However, which tissue type induces NMJ disruption; be it the motoneurons (hMN), Schwann cells or skeletal muscle (hSKM) remains unresolved. While mechanisms by which ALS hMN contribute to NMJ dysfunction are well-described in literature, limited information exist on how the other tissue types in the tripartite synapse (hSKM and Schwann cells) induce and/or contribute to ALS NMJ disruption. A fair understanding of the role of each tissue type in NMJ dysfunction would help shape the trajectory of future ALS research and …

Conservative Management Of Low Back Pain, Se Won Lee, Dan Nguyen, Denny Mack, Eric Aguila, Mary Thomas, Karyn Doddy

HCA Healthcare Journal of Medicine

Low back pain (LBP) is frequently encountered in outpatient clinics and affects individual patients and society in general with decreased physical function, quality of life, disability, and/or economic burden. Although most acute LBP resolves on its own, recurrent and chronic LBP is a common reason for outpatient clinic visits. This review explores pragmatic approaches to LBP in the clinical setting, focusing on recognizing prognostic factors, initial approaches to evaluation, including selective imaging, and conservative management including patient education, therapeutic exercises and bracing.
