Redefining Recovery: Multimodal Analgesics And Tranexamic Acid In Orthopedic Surgery, Elijah Hoffman

Bone Bulletin

Introduction As the demand for joint replacements continues to rise, optimizing patient outcomes and enhancing recovery have become paramount goals for orthopedic surgeons. Patients used to have minimal mobility following a Total Knee Arthroplasty (TKA) or Total Hip Arthroplasty (THA) due to pain or the effects of sedation from anesthesia. This would lead to longer hospital stays, more complications, and higher opioid use.¹ These surgeries also resulted in levels of blood loss that required transfusion therapy postoperatively.² In recent years, there has been a paradigm shift in postoperative care for total joint arthroplasty (TJA), marked by significant advancements …

Participation in sports during adolescence is beneficial for participants as it improves fitness, enhances psychosocial development, increases academic performance, and boosts self-esteem.¹ One of the most popular sports among adolescent athletes is baseball, with nearly 500,000 high school players in the United States in 2020.1 While participation in sports has been shown to have clear benefits and has been steadily increasing, recent decades have also seen a dramatic rise in the level of competition.² As a direct result, there has been an increase in the prevalence of early sports specialization (ESS) with an estimated 14-47% of adolescent …

The Ins And Outs Of Wide-Awake Hand Surgery, Molly Milano

Bone Bulletin

Introduction

As the name might imply, “wide awake local anesthesia no tourniquet” (WALANT) is a surgical method to perform hand surgery using only a local anesthetic without the use of a tourniquet or any sedation and general anesthetics. The WALANT technique takes advantage of the vasoconstrictive effects of epinephrine combined with the local anesthetic effects of lidocaine to create a surgical field that does not require a tourniquet or general anesthesia.¹ The main contributor is epinephrine, which decreases bleeding in the surgical field while also lengthening lidocaine’s absorption and effect.² When first introduced to the surgical world, the …

Evaluating Bone Fracture Healing Utilizing Novel Ultrasound Modes, X-Ray And Dual-Energy X-Ray Absorptiometry In A Rabbit Model, Priscilla Machado, Rachel Blackman, Ji-Bin Liu, Flemming Forsberg, Traci Fox

Department of Radiology Posters

Background and Purpose

Healing in bone fractures is a complex process involving local inflammation, angiogenesis (i.e., the creation of new blood vessels), and formation of a bone-building callus, all of which leads to returning the bone nearly to its pre-fracture state. This is the process in a bone where the fracture is clean and the fractured ends oppose each other. Five to 10 percent of fractures are described as non-union, which can lead to poor healing and long-term complications. The purpose of this study was to compare fracture healing in a rabbit model using x-ray, the traditional method for evaluating …

Chronic Progressive External Ophthalmoplegia, Bahram Pashaee, Mph, Bs

inSIGHT

Chronic progressive external ophthalmoplegia is an inherited or sporadic form of dystrophy that preferentially affects the extraocular muscles of the eye. While this dystrophy can manifest systemically, the extraocular muscles are commonly involved due to their constant metabolic demands and vulnerability to oxidative stress.¹ This preferential involvement of the eyelid levator muscle and extraocular muscles makes CPEO an important condition to consider in a differential diagnosis for eyelid asymmetry and double vision among other conditions such as myasthenia gravis, thyroid-associated ophthalmoplegia, and other mitochondrial myopathies.² This dystrophy tends to occur in the third or fourth decade of life. …

Evolution Of Lamellar Keratoplasty, Ishan Kasat, Bs

inSIGHT

Overview of Keratoplasty The evolution of corneal transplantation, or keratoplasty, has seen a paradigm shift from traditional penetrating keratoplasty (PKP) to the refined precision of lamellar keratoplasty (LK). Penetrating, or full thickness, keratoplasty is a replacement of all corneal layers: epithelium, Bowman's layer, stroma, Descemet's membrane, and endothelium.¹ Lamellar, or partial thickness, keratoplasty involves replacement of either epithelium and stroma (anterior lamellar) or Descemet’s membrane and endothelium (posterior lamellar).² From 1985 to 2004, over 95% of graft tissues were used for PKP. However, from 2005 to 2014, the percentage of PKP procedures decreased from 95% to 42%, while …

The Myopia Epidemic: Exploring The Pathology And Management Of The World’S Most Common Eye Disorder, Gabriella Baldassarre, Bs

inSIGHT

Myopia is the most common eye disorder in the world and an increasing cause of vision impairment in children.¹ Myopia is an imbalance in the refractive components of the eye and its length, leading to inaccurate focusing of light rays in front of the retina tissue instead of on it. There is a spectrum of severity of myopia, from mild nearsightedness to a more severe form known as high or degenerative myopia, which has the potential to cause vision loss and blindness. There is evidence of a developing myopia epidemic, with an estimated one-third of the world population affected …

Discovery Of A Small-Molecule Inhibitor That Traps Polθ On Dna And Synergizes With Parp Inhibitors, William Fried, Mrityunjay Tyagi, Leonid Minakhin, Gurushankar Chandramouly, Taylor Tredinnick, Mercy Ramanjulu, William Auerbacher, Marissa L Calbert, Timur Rusanov, Trung Hoang, Nikita Borisonnik, Robert Betsch, John Krais, Yifan Wang, Umeshkumar Vekariya, John Gordon, George Morton, Tatiana Kent, Tomasz Skorski, Neil Johnson, Wayne Childers, Xiaojiang Chen, Richard Pomerantz

Department of Biochemistry and Molecular Biology Faculty Papers

The DNA damage response (DDR) protein DNA Polymerase θ (Polθ) is synthetic lethal with homologous recombination (HR) factors and is therefore a promising drug target in BRCA1/2 mutant cancers. We discover an allosteric Polθ inhibitor (Polθi) class with 4-6 nM IC₅₀ that selectively kills HR-deficient cells and acts synergistically with PARP inhibitors (PARPi) in multiple genetic backgrounds. X-ray crystallography and biochemistry reveal that Polθi selectively inhibits Polθ polymerase (Polθ-pol) in the closed conformation on B-form DNA/DNA via an induced fit mechanism. In contrast, Polθi fails to inhibit Polθ-pol catalytic activity on A-form DNA/RNA in which the enzyme binds in …

Role Of Mechanoregulation In Mast Cell-Mediated Immune Inflammation Of The Smooth Muscle In The Pathophysiology Of Esophageal Motility Disorders, Raj Goyal, Satish Rattan

Division of Gastroenterology and Hepatology Faculty Papers

Major esophageal disorders involve obstructive transport of bolus to the stomach, causing symptoms of dysphagia and impaired clearing of the refluxed gastric contents. These may occur due to mechanical constriction of the esophageal lumen or loss of relaxation associated with deglutitive inhibition, as in achalasia-like disorders. Recently, immune inflammation has been identified as an important cause of esophageal strictures and the loss of inhibitory neurotransmission. These disorders are also associated with smooth muscle hypertrophy and hypercontractility, whose cause is unknown. This review investigated immune inflammation in the causation of smooth muscle changes in obstructive esophageal bolus transport. Findings suggest that …
