When It Isn’T Always Lyme: Expanding The Differential Diagnosis For Acute-Onset Polyarthralgia In The West Virginia Eastern Panhandle, Natalie A. Moffett, Rosemarie Lorenzetti 2016 West Virginia University

When It Isn’T Always Lyme: Expanding The Differential Diagnosis For Acute-Onset Polyarthralgia In The West Virginia Eastern Panhandle, Natalie A. Moffett, Rosemarie Lorenzetti

Marshall Journal of Medicine

This case presentation discusses a 36 year-old female animal care worker presenting with an acute-onset polyarthropathy during the summer months in a Lyme endemic region. Though she appeared to be a good candidate for the diagnosis of Lyme borreliosis, her screening serology reported negative results and alternative diagnoses were considered. Her subsequent diagnosis with parvovirus B19 acts to remind the general practitioner to have confidence in the accuracy of a negative Lyme screen and, upon negative result, to expand the differential to include less common infections including parvovirus B19. It also highlights the need to remember parvovirus B19 in a ...

A premature termination codon (PTC) in the ORF of an mRNA generally leads to production of a truncated polypeptide, accelerated degradation of the mRNA, and depression of overall mRNA expression. Accordingly, nonsense mutations cause some of the most severe forms of inherited disorders. The small-molecule drug ataluren promotes therapeutic nonsense suppression and has been thought to mediate the insertion of near-cognate tRNAs at PTCs. However, direct evidence for this activity has been lacking. Here, we expressed multiple nonsense mutation reporters in human cells and yeast and identified the amino acids inserted when a PTC occupies the ribosomal A site in ...


Disability And Return To Work Following Musculoskeletal Injury, Qiyun Shi 2016 The University of Western Ontario

Disability And Return To Work Following Musculoskeletal Injury, Qiyun Shi

Electronic Thesis and Dissertation Repository

Musculoskeletal disorders (MSDs) are injuries, damage or disorders affecting the musculoskeletal system including muscles, ligaments, nerves, tendons, bones or cartilage etc. MSDs are highly prevalent and associated with sickness absence, reduced work efficiency, job changes and earlier retirement.. They also affect daily activity and social functioning. Although many MSDs are accompanied by minor symptoms and settled spontaneously, approximately 10% of the workforce with MSDs have difficulty resuming their original work or exit the workforce permanently. Return to work after MSDs is complex, and is influenced by many factors including physical, psychological, economic and social factors.

Although there are extensive studies ...

A Comparison Of Cervical And Trunk Musculoskeletal Characteristics Between Female And Male Army Helicopter Pilots, Takashi Nagai, Karen A. Keenan, John P. Abt, Timothy C. Sell, Brian W. Smalley, Michael D. Wirt, Scott M. Lephart 2016 University of Pittsburgh

A Comparison Of Cervical And Trunk Musculoskeletal Characteristics Between Female And Male Army Helicopter Pilots, Takashi Nagai, Karen A. Keenan, John P. Abt, Timothy C. Sell, Brian W. Smalley, Michael D. Wirt, Scott M. Lephart

International Journal of Aviation, Aeronautics, and Aerospace

Introduction: Neck pain (NP) and low back pain (LBP) are prevalent among military helicopter pilots. Although there have been few studies on sex differences in the NP/LBP prevalence in this population, females are shown to be at a greater risk of NP/LBP in civilian studies. This disparity may be due to musculoskeletal characteristics differences that predispose females for NP/LBP. The purpose of this study was to compare cervical and trunk musculoskeletal characteristics between male and female pilots. Methods: A total of 8 female pilots (Age: 27.6 ± 4.2yrs, HT: 166.1 ± 7.7cm, WT: 67.9 ...

Cell and Developmental Biology Publications and Presentations

Derepression of DUX4 in skeletal muscle has emerged as a likely cause of pathology in facioscapulohumeral muscular dystrophy (FSHD). Here we report on the use of antisense phosphorodiamidate morpholino oligonucleotides to suppress DUX4 expression and function in FSHD myotubes and xenografts. The most effective was phosphorodiamidate morpholino oligonucleotide FM10, which targets the polyadenylation signal of DUX4. FM10 had no significant cell toxicity, and RNA-seq analyses of FSHD and control myotubes revealed that FM10 down-regulated many transcriptional targets of DUX4, without overt off-target effects. Electroporation of FM10 into FSHD patient muscle xenografts in mice also down-regulated DUX4 and DUX4 targets. These ...

Open Access Articles

BACKGROUND: The relationship between lung and joint inflammation in rheumatoid arthritis is poorly understood. Lung inflammation with resultant protein citrullination may trigger anti-citrullinated protein antibodies, inflammation, and arthritis. Alternatively, lung and joint inflammation may be two manifestations of a single underlying pathology. The lung has increased citrullination and TNF-alpha levels are high in rheumatoid arthritis; however, it is unknown if TNF-alpha can induce lung protein citrullination. The citrullinating enzyme peptidylarginine deiminase 4 (PAD4) exacerbates TNF-alpha-induced arthritis, but a role for PAD4 in lung citrullination and TNF-alpha-induced lung inflammation has not been explored. Our aim was to use TNF-alpha-overexpressing mice to ...


Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock 2016 The University of Western Ontario

Inpatient Versus Outpatient Total Hip Arthroplasty, Michael Pollock

Electronic Thesis and Dissertation Repository

We conducted a randomized controlled trial to evaluate patients undergoing a total hip arthroplasty (THA) who were discharged from the hospital either on the day of surgery (outpatient) or were admitted overnight following surgery (inpatient). Our primary outcome was the rate of serious adverse events during the first three months postoperatively. Secondary outcome measures included cost, patient satisfaction, functional outcomes, quality of life and pain. We found no statistically significant difference between the two groups in serious adverse events. We found that outpatient THA was less expensive from the perspectives of the hospital and ministry of health; but the difference ...

Paul R. Odgren PhD

Mutations in sorting nexin 10 (Snx10) have recently been found to account for roughly 4% of all human malignant osteopetrosis, some of them fatal. To study the disease pathogenesis, we investigated the expression of Snx10 and created mouse models in which Snx10 was knocked down globally or knocked out in osteoclasts. Endocytosis is severely defective in Snx10-deficient osteoclasts, as is extracellular acidification, ruffled border formation, and bone resorption. We also discovered that Snx10 is highly expressed in stomach epithelium, with mutations leading to high stomach pH and low calcium solubilization. Global Snx10-deficiency in mice results in a combined phenotype: osteopetrosis ...

Biosimilars remain a hot topic in rheumatology, and some physicians are cautious about their application in the real world. With many products coming to market and a wealth of guidelines and recommendations concerning their use, there is a need to understand the changing landscape and the real clinical and health-economic potential offered by these agents. Notably, rheumatologists will be at the forefront of the use of biosimilar monoclonal antibodies/soluble receptors. Biosimilars offer cost savings and health gains for our patients and will play an important role in treating rheumatic diseases. We hope that these lower costs will compensate for ...

Calcium Phosphate As A Key Material For Socially Responsible Tissue Engineering, Vuk Uskoković, Victoria M. Wu

Pharmacy Faculty Articles and Research

Socially responsible technologies are designed while taking into consideration the socioeconomic, geopolitical and environmental limitations of regions in which they will be implemented. In the medical context, this involves making therapeutic platforms more accessible and affordable to patients in poor regions of the world wherein a given disease is endemic. This often necessitates going against the reigning trend of making therapeutic nanoparticles ever more structurally complex and expensive. However, studies aimed at simplifying materials and formulations while maintaining the functionality and therapeutic response of their more complex counterparts seldom provoke a significant interest in the scientific community. In this review ...

Proteins containing citrulline, a post-translational modification of arginine, are generated by peptidyl arginine deiminases (PAD). Citrullinated proteins have pro-inflammatory effects in both innate and adaptive immune responses. Here, we examine the therapeutic effects in collagen-induced arthritis of the second generation PAD inhibitor, BB-Cl-amidine. Treatment after disease onset resulted in the reversal of clinical and histological changes of arthritis, associated with a marked reduction in citrullinated proteins in lymph nodes. There was little overall change in antibodies to collagen or antibodies to citrullinated peptides, but a shift from pro-inflammatory Th1 and Th17-type responses to pro-resolution Th2-type responses was demonstrated by serum ...
