Musculoskeletal Tumors Disguised As Orthopedic Injuries: A Case Report, A Summers

Clinical Practice in Athletic Training

Background: Musculoskeletal tumors are relatively rare, accounting for only 0.2 to 0.5% of all malignancies across all age groups. More specifically, Pigmented Villonodular Synovitis, a type of musculoskeletal tumor, has an incidence rate of 1.8 cases per one million people in a population. This benign, proliferative disease is a type of tenosynovial giant cell tumor that can affect the soft tissue lining of joints, bursae, and tendon sheaths. These joint-related tumors often present with an insidious onset and non-specific physical exam findings. Therefore, they are often mistaken for other, more common orthopedic injuries, making them difficult to diagnose. Patient Information: …

Enhancing Clinic Efficiency: A Quality Improvement Initiative For Postoperative Patient Care In An Outpatient Orthopedic Physician Practice Setting, D Stepan, T Jp Greffly, R M. Williams

Clinical Practice in Athletic Training

Introduction: Following orthopedic surgery, patient post-operative (post-op) visits are deemed global surgical observations where day 00 to day 90 are appointments that cannot be billed. Patients are typically seen 3 times during this global period. Thus, the outpatient clinic needs to have non-billable time slots each day for these patients. The current scheduling model double books patients every 15 minutes, with the physician being the primary provider seeing patients for post-op visits. Therefore, the clinic has demonstrated inefficiencies with scheduling these patients while having sufficient appointments available for billable patients. This quality improvement initiative aimed to decrease post-op patient visits …

Staying Sane In The Membrane: Neutral Sphingomyelinase 2 As A Master Regulator Of Plasma Membrane Ceramide, Zainuddin Quadri, Erhard Bieberich

Markey Cancer Center Faculty Publications

Ceramide, a key signaling sphingolipid in the plasma membrane, plays a pivotal role in fundamental cellular processes such as adhesion, polarity, and programmed cell death. The generation of plasma membrane ceramide is largely attributed to the activity of two types of sphingomyelinases: neutral sphingomyelinase 2 (nSMase2, Smpd3) and acid sphingomyelinase (aSMase, Smpd1). While many studies have explored ceramide generation following experimental activation of these enzymes, the mechanisms governing basal or steady- state ceramide levels have remained poorly understood. Using an innovative mass spectrometry approach developed in the Canals’ lab, the team has quantified the distinct contributions of nSMase2 and aSMase …

Bilirubin Bioconversion To Urobilin In The Gut-Liver-Kidney Axis: A Biomarker For Insulin Resistance In The Cardiovascular-Kidney-Metabolic (Ckm) Syndrome, Zachary A. Kipp, Olufunto O. Badmus, David E. Stec, Brantley Hall, Terry D. Hinds Jr.

Markey Cancer Center Faculty Publications

The rising rates of obesity worldwide have increased the incidence of cardiovascular disease (CVD), making it the number one cause of death. Higher plasma bilirubin levels have been shown to prevent metabolic dysfunction and CVD. However, reducing levels leads to deleterious outcomes, possibly due to reduced bilirubin half-life that escalates the production of its catabolized product, urobilinogen, produced by gut bacteria and naturally oxidized to urobilin. Recent findings suggest that the involvement of the microbiome catabolism of bilirubin to urobilin and its absorption via the hepatic portal vein contributes to CVD, suggesting a liver-gut axis involvement. We discuss the studies …

Determining The Physiological And Behavioral Tolerance To Hypoxia In Two Species Of Rockfish (Sebastes Spp.), Makenna Chan

Theses

In the eastern North Pacific, the oxygen minimum zone naturally shoals seasonally and impacts demersal fish habitat along the continental margins and on offshore seamounts. This hypoxic layer has been shoaling in recent decades, likely affecting the habitat and distribution of commercially-important fish species such as rockfishes (genus Sebastes). Respirometry and shuttle box behavioral experiments were used to determine the hypoxia sensitivities of two rockfish species with contrasting movement patterns and habitat use: cowcod (Sebastes levis) and bocaccio (Sebastes paucispinis). Although both species inhabit similar deep-water, rocky-reef habitat, they have different lifestyles, in which cowcod …
