ASA Multidisciplinary Research Symposium

Dermatomyositis is a rare disease which affects the skin and muscles. This disease can manifest in children or not present until one is older. Since this disease is so rare, most individuals who are diagnosed with it will have a team of physicians who work together to help treat the patient.


Effects Of Revision Surgery On Grade Of Adverse Local Tissue Reaction Following Recall Of A Modular Hip Implant, Joseph F. Davies, Danielle M. Greer, Susan Truchan 2017 Aurora Advanced Orthopedics

Effects Of Revision Surgery On Grade Of Adverse Local Tissue Reaction Following Recall Of A Modular Hip Implant, Joseph F. Davies, Danielle M. Greer, Susan Truchan

Journal of Patient-Centered Research and Reviews

Background: The Stryker Rejuvenate modular hip implant device allows for greater versatility in matching a patient’s anatomy than conventional implants. Device recalls and in vivo metal hypersensitivity after total hip arthroplasty (THA) are common. However, recall of the Rejuvenate implant represents one of the largest recall volumes to date, highlighting our uncertainty regarding causes of device metal fretting/corrosion and adverse local tissue reaction (ALTR). While devices with metal-on-metal bearings historically were culprits for release of metal debris, more recently developed modular-neck devices add opportunity for adjacent metal components to rub together. With the Rejuvenate device, corrosion or fretting ...

Exon skipping is a promising therapeutic strategy for Duchenne muscular dystrophy (DMD), employing morpholino antisense oligonucleotides (PMO-AO) to exclude disruptive exons from the mutant DMD transcript and elicit production of truncated dystrophin protein. Clinical trials for PMO show variable and sporadic dystrophin rescue. Here, we show that robust PMO uptake and efficient production of dystrophin following PMO administration coincide with areas of myofiber regeneration and inflammation. PMO localization is sustained in inflammatory foci where it enters macrophages, actively differentiating myoblasts and newly forming myotubes. We conclude that efficient PMO delivery into muscle requires two concomitant events: first, accumulation and retention ...

The myotonic dystrophies are prototypic toxic RNA gain-of-function diseases. Myotonic dystrophy type 1 (DM1) and type 2 (DM2) are caused by different unstable, noncoding microsatellite repeat expansions - (CTG)DM1 in DMPK and (CCTG)DM2 in CNBP Although transcription of mutant repeats into (CUG)DM1 or (CCUG)DM2 appears to be necessary and sufficient to cause disease, their pathomechanisms remain incompletely understood. To study the mechanisms of (CCUG)DM2 toxicity and develop a convenient model for drug screening, we generated a transgenic DM2 model in the fruit fly Drosophila melanogaster with (CCUG)n repeats of variable length (n=16 and 106 ...

Age-Dependent Changes In The Articular Cartilage And Subchondral Bone Of C57bl/6 Mice After Surgical Destabilization Of Medial Meniscus, Henry Huang, Jordan D. Skelly, David C. Ayers, Jie Song

Jie Song

Age is the primary risk factor for osteoarthritis (OA), yet surgical OA mouse models such as destabilization of the medial meniscus (DMM) used for evaluating disease-modifying OA targets are frequently performed on young adult mice only. This study investigates how age affects cartilage and subchondral bone changes in mouse joints following DMM. DMM was performed on male C57BL/6 mice at 4 months (4 M), 12 months (12 M) and 19+ months (19 M+) and on females at 12 M and 18 M+. Two months after surgery, operated and unoperated contralateral knees were harvested and evaluated using cartilage histology scores ...

Alternative Interventions For Children Coping With Chronic Conditions: A Critical Review Of The Literature, Nina M. Pelsi, Kim S. Amer

DePaul Discoveries

Reduction of stressors and anxiety levels in adolescents with chronic illnesses is a critical concept in pediatric health care in America today. The many stressors associated with chronic illness include displaying physical and mental differences, social stigma, financial difficulty, and family stress. These stressors may affect the adolescent’s ability to learn and cope in everyday life. The current research was a critical review of the literature examining studies done with adolescents coping with chronic diseases and illnesses. The aim was to analyze the most efficacious non-pharmacological methods for reducing stressors in adolescents with chronic illness. A critical review of ...

OBJECTIVE: Investigate whether the efficacy and safety of intravenous tocilizumab (TCZ) demonstrated at week 52 in patients with early rheumatoid arthritis (RA) are maintained to week 104.

METHODS: Methotrexate (MTX)-naive patients with early progressive RA were randomly assigned to double-blind 4 mg/kg TCZ+MTX, 8 mg/kg TCZ+MTX, 8 mg/kg TCZ+placebo or placebo+MTX for 104 weeks. Patients not receiving 8 mg/kg TCZ and not achieving Disease Activity Score-28 joints (DAS28-erythrocyte sedimentation rate (ESR)) < /=3.2 at week 52 switched to escape therapy (8 mg/kg TCZ+MTX). Analyses were exploratory.

RESULTS: Intent-to-treat and safety populations included 1157 and 1153 patients, respectively. DAS28-ESR remission ( < 2.6) rates were maintained from weeks 52 to 104 (eg, 8 mg/kg TCZ+MTX, 49.3% to 47.6%). Placebo+MTX and 4 mg/kg TCZ+MTX escape patients' week 104 response rates were 51.4% and 30.5%, respectively. Inhibition of radiographic progression was maintained with 8 mg/kg TCZ (eg, 8 mg/kg TCZ+MTX mean (SD) change from baseline in modified total Sharp score: 0.13 (1.28), week 52; 0.19 (2.08), week 104). The safety profile of TCZ was consistent with that of previous reports.

CONCLUSIONS: Patients with early RA treated with ...


Lacunar-Canalicular Network In Femoral Cortical Bone Is Reduced In Aged Women And Is Predominantly Due To A Loss Of Canalicular Porosity, A. M. Ashique, L. S. Hart, C. D. L. Thomas, J. G. Clement, P. Pivonka, Yasmin Carter, D. D. Mousseau, D. M. L. Cooper 2017 University of Saskatchewan

Lacunar-Canalicular Network In Femoral Cortical Bone Is Reduced In Aged Women And Is Predominantly Due To A Loss Of Canalicular Porosity, A. M. Ashique, L. S. Hart, C. D. L. Thomas, J. G. Clement, P. Pivonka, Yasmin Carter, D. D. Mousseau, D. M. L. Cooper

Open Access Articles

The lacunar-canalicular network (LCN) of bone contains osteocytes and their dendritic extensions, which allow for intercellular communication, and are believed to serve as the mechanosensors that coordinate the processes of bone modeling and remodeling. Imbalances in remodeling, for example, are linked to bone disease, including fragility associated with aging. We have reported that there is a reduction in scale for one component of the LCN, osteocyte lacunar volume, across the human lifespan in females. In the present study, we explore the hypothesis that canalicular porosity also declines with age. To visualize the LCN and to determine how its components are ...

Validity Of The Nurses' Health Study Physical Activity Questionnaire In Estimating Physical Activity In Adults With Rheumatoid Arthritis, Thomas Quinn, Michelle Frits, Johan Von Heideken, Christine Iannaccone, Nancy A. Shadick, Michael Weinblatt, Maura D. Iversen

Open Access Articles

BACKGROUND: Patients with rheumatoid arthritis (RA) demonstrate reduced aerobic capacity, excess cardiovascular risk, mobility limitations and are less physically active than their healthy peers. Physical activity may decrease RA disease activity through its anti-inflammatory effects and psychological and health benefits. To successfully manage RA symptoms and reduce cardiovascular risks associated with RA through increased physical activity (PA), accurate physical activity assessments are critical. Accelerometry is an objective physical activity measure, but not widely used. Validity of the Nurses' Health Study physical activity questionnaire II (NHSPAQ) has not been determined for estimation of physical activity in RA. This study examined NHSPAQ ...

Objectives: Smoking is strongly associated with an increased risk of psoriatic arthritis (PsA) in the general population, but not among psoriasis patients. We sought to clarify the possible methodologic mechanisms behind this paradox.

Methods: Using 1995-2015 data from The Health Improvement Network, we performed survival analysis to examine the association between smoking and incident PsA in the general population and among psoriasis patients. We clarified the paradox using mediation analysis and conducted bias sensitivity analyses to evaluate the potential impact of index event bias and quantify its magnitude from uncontrolled/unmeasured confounders.

Results: Of 6.65 million subjects without PsA ...


Macroglossia In Inclusion Body Myositis, Jatinder S. Patti, Kate Daniello, Lan Qin 2017 University of Massachusetts Medical School

Macroglossia In Inclusion Body Myositis, Jatinder S. Patti, Kate Daniello, Lan Qin

UMass Center for Clinical and Translational Science Research Retreat

OBJECTIVE: Discussion of a case of Inclusion body myositis (IBM) associated with macroglossia.

INTRODUCTION: IBM is one of the idiopathic inflammatory myopathies. Exact pathogenesis is unclear but there is an evidence of dysregulation of antigen driven immune response involving T cells. Typical onset is slowly progressive impacting quadriceps often more than hip flexors, ankle dorsiflexors and distal forearm flexor muscles. Swallowing difficulties often are present and mild facial weakness can be seen. Macroglossia has never been reported in association with IBM. In fact inflammatory myopathies of tongue are a rarity.

DESIGN: A case report of a 68 year old woman ...

OBJECTIVE: Discussion of a rare case of dermatomyositis associated with tonsillar neoplasm in an African American woman.

BACKGROUND: Dermatomyositis is a syndrome of inflamatory myopathy with multiorgan manifestations which has been linked to immune dysregulation and neoplasia.

INTRODUCTION: Many studies have shown five to seven fold increased risk of developing malignancy with dermatomyositis within two years of presentation. Most common cancers reported are adenocarcinomas of lung, breast, ovaries, stomach, pancreas and bladder. Dermatomyositis as a paraneoplastic manifestation of tonsillar squamous cell carcinoma has not previously been described.

DESIGN: This is a case report of a 52 year old woman who ...


C1qbp Inhibits Dux4-Dependent Gene Activation And Can Be Targeted With 4mu, Alec M. DeSimone, Genila Bibat, Kathryn Wagner, Guido Stadler, Woodring E. Wright, John D. Leszyk, Charles P. Emerson Jr. 2017 University of Massachusetts Medical School

C1qbp Inhibits Dux4-Dependent Gene Activation And Can Be Targeted With 4mu, Alec M. Desimone, Genila Bibat, Kathryn Wagner, Guido Stadler, Woodring E. Wright, John D. Leszyk, Charles P. Emerson Jr.

UMass Center for Clinical and Translational Science Research Retreat

FSHD is linked to the misexpression of the DUX4 gene contained within the D4Z4 repeat array on chromosome 4. The gene encodes the DUX4 protein, a cytotoxic transcription factor that presumably causes the symptoms of the disease. However, individuals have been identified who express DUX4 in their muscle biopsies, but who remain asymptomatic, suggesting that there are other factors that modify FSHD penetrance or severity. We hypothesized that an FSHD-modifying factor would physically interact with DUX4, and we took a proteomic approach to identify DUX4-interacting proteins. We identified the multifunctional C1QBP protein as one such factor. C1QBP is known to ...
