What Outcomes Matter To Patients After Joint Or Spine Surgery?, Robin R. Whitebird, Leif I. Solberg, Christine K. Norton, Jeanette Y. Ziegenfuss, Stephen E. Asche, Elizabeth S. Grossman

Journal of Patient-Centered Research and Reviews

Purpose: Patient-reported outcome measures (PROMs) are increasingly used in clinical care, but there have been few studies of what patients identify as the most important outcomes.

Methods: Semi-structured interviews were conducted with 65 patients undergoing hip or knee replacement, spinal discectomy/laminotomy, or a spinal fusion. Interviews focused on outcomes patients identified as important, perceived usefulness of standardized PROMs measures, and contextual situations important to their care. Data were analyzed using a directed content analysis approach.

Results: Patients identified desired outcomes that were unique and important to them. Their preferred outcomes focused in the areas of freedom from pain, getting back …

A Closer Look At Muscle Breakdown: An Overview Of The Causes, Complications, And Diagnostics Of Rhabdomyolysis, Jamie Holchin

Senior Honors Theses

Rhabdomyolysis is the rapid breakdown of myocytes in skeletal muscle. This condition can be triggered by a variety of things including crush injury, drugs, prolonged exercise, and venom. Although the causes can vary, the general pathophysiology of rhabdomyolysis is similar. Increased intracellular calcium ion levels instigate the breakdown of cellular and certain organelle membranes of muscle cells. Reactive oxygen species form, ATP is depleted, and the sarcoplasmic reticulum, which regulates muscle contraction, is also damaged. Necrosis ensues, leading to toxic intracellular components spreading throughout the body. Rhabdomyolysis can then lead to several complications including acute renal injury and heart arrhythmias, …

Cd44 Receptor Mediates Urate Crystal Phagocytosis By Macrophages And Regulates Inflammation In A Murine Peritoneal Model Of Acute Gout, Emira Bousoik, Marwa Qadri, Khaled A. Elsaid

Pharmacy Faculty Articles and Research

Gout is a chronic arthritis caused by the deposition of poorly soluble monosodium urate monohydrate (MSU) crystals in peripheral joints. Resident macrophages initiate inflammation in response to MSU mediated by NF-κB nuclear translocation and NLRP3 inflammasome activation. We investigated the role of CD44, a transmembrane receptor, in mediating MSU phagocytosis by macrophages. We used an antibody that sheds the extracellular domain (ECD) of CD44 to study the role of the receptor and its associated protein phosphatase 2A (PP2A) in macrophage activation. We also studied the significance of CD44 in mediating MSU inflammation in-vivo. Cd44^−/− BMDMs showed reduced MSU …

Comparison Of Pre- And Post-Operative Shoulder Muscle Emg Profiles In Reverse Total Shoulder Arthroplasty Patients, Emily Lau, Sreten Franovic, Noah Kuhlmann, Eric C. Makhni Md, Stephanie Muh Md

Medical Student Research Symposium

Background: Deltoid muscle function is central in reverse total shoulder arthroplasty (RTSA) function; however, there is limited information available regarding changes in deltoid activity before and after surgery. Few tests exist to evaluate specific muscle metrics pre and post operatively. Surface Electromyographic (EMG) is non-invasive and allows for observation of motions with multifaceted analysis of movement with minimal patient demand. Understanding the changes in shoulder muscle activation, namely in the deltoid, in patients pre and post-RTSA can further advance understanding of the procedure and rehabilitation efforts.

Methods: Nine individuals were recruited for this study: all patients underwent RTSA by a …

Rapports de recherche scientifique

Environ une personne sur trois dans le monde vivrait avec un trouble musculosquelettique (TMS) persistant. Plusieurs auteurs soulignent l’influence significative des facteurs psychosociaux, dont l’anxiété, sur le développement de l’incapacité prolongée. Associées à l’anxiété, des inquiétudes excessives ont été documentées chez des travailleurs ayant une douleur persistante d’origine musculosquelettique. Les inquiétudes ne favorisent pas l’adaptation en contexte d’une situation problématique. Cependant, aucune étude n’a jusqu’à présent tenté de comprendre ces inquiétudes, en lien avec l’environnement de travail. Une meilleure compréhension de ce phénomène semble un incontournable pour offrir une action mieux ciblée aux travailleurs ayant une incapacité au travail prolongée. …

Development Of A Sox9 Reporter Cell For High-Throughput Chondrogenic Assessment, Alyssa R. Mickle

Honors Undergraduate Theses

Osteoarthritis (OA) is a debilitating disease caused by the deterioration of articular cartilage and is a leading cause of disability in the United States and worldwide. Much current research into improved treatment for this disease is focused on tissue engineering through the growth of cartilage sheets made by articular chondrocytes. However, as chondrocytes proliferate in vitro, they also lose their ability to produce dense extracellular matrix, a necessary component of articular cartilage conferring mechanical strength. SOX9, a transcriptional activator, increases type II collagen expression, a key articular cartilage extracellular matrix component. Thus, SOX9 promotes an articular cartilage phenotype. Therefore, …

Anterior Cruciate Ligament Injury-Induced Alterations In Inflammation And Muscle Physiology, Emily R. Hunt

Theses and Dissertations--Rehabilitation Sciences

Long term weakness and atrophy of the quadriceps muscle are a direct result of anterior cruciate ligament (ACL) injuries and persist for up to 10 years post injury. Muscle atrophy ensues regardless of ligamentous reconstruction surgery, indicating that muscle atrophy following injury is a function of the ligament rupture and not reconstruction surgery. Elucidating the mechanisms underlying quadriceps atrophy following ACL rupture is crucial for developing interventions to restore proper quadriceps size and mitigate weakness thereby allowing for improved patient function. In addition to understanding the specific mechanisms that contribute to quadriceps atrophy following ACL rupture, the timing of atrophic …

Donor Age Effects On The Proliferative And Chondrogenic/Osteogenic Differentiation Performance Of Equine Bone Marrow- And Adipose Tissue Derived Mesenchymal Stem Cells In Culture, Jasmin Bagge

Theses and Dissertations--Veterinary Science

Orthopedic injuries are a major cause of lameness and morbidity in horses. Bone marrow (BM)- and adipose tissue (AT) derived mesenchymal stem cells (MSCs) have shown potential to facilitate the repair of orthopedic injuries and are being used increasingly in veterinary clinics. Presently, the use of MSCs as a therapy for equine patients is most commonly applied as autologous transplants, using BM- and AT-MSCs harvested from the patient shortly after the time of injury. Cell-based therapies are therefore delayed to enable primary cell numbers to be expanded in culture. Of concern, however, are human and rodent studies that have shown …

Comparative Chondrogenesis Of Interzone And Anlagen Cells In Equine Skeletal Development, Chanhee Mok

Theses and Dissertations--Veterinary Science

At the presumptive sites of future synovial joints during mammalian skeletogenesis, articular cartilage develops from interzone located between the cartilaginous anlagen of bones. Thus, two types of cartilaginous tissues differentiate in close proximity. While anlagen cartilage is transient, progressing through endochondral ossification to form bones, articular cartilage is stable and functions throughout life to facilitate both low friction movement and load distribution. Despite important life-long functional properties, articular cartilage has a very limited intrinsic ability to repair structural defects. On the other hand, structural lesions in bones generally heal well by forming a cartilaginous callus and recapitulating endochondral ossification to …

Oral Contraceptives As Possible Acl Injury Prevention Method, Haley Schweizer

Études primaires

Immediate biomechanical and functional effects of knee braces are often reported, however, the duration and type of knee brace treatment for knee osteoarthritis (KOA) remain unclear. The objective was to evaluate usage, comfort, pain, and knee adduction moment (KAM) of three knee braces each worn 3 months by patients. Twenty-four patients with KOA were assigned in a randomized crossover trial a valgus three-point bending system brace (V3P-brace), an unloader brace with valgus and external rotation functions (VER-brace) and a stabilizing brace used after ligament injuries (ACL-brace). Functional questionnaires and gait assessment were carried out before and after each brace wear …

Characterization Of Bone Pathology In Sickle Cell Disease And Therapeutic Strategies, Mykel D. Green

Dissertations and Theses

Sickle cell disease (SCD) is a genetic hemoglobinopathy that has grown into a global health concern. While the advances in medical treatment and management of SCD during childhood have drastically improved the overall survival of children, the transition from pediatric to adult services is significantly inadequate in comparison. Life expectancies of patients with SCD in first world countries such as the United States are shortened to averages of 42 and 48 years for men and women, respectively. Despite the increasing number of people living with SCD, remarkably, few detailed studies have described the clinical course and complications of the disease …
