Department of Orthopaedic Surgery Faculty Papers

Recent studies have highlighted the importance of mitochondria in NP cells and articular chondrocyte health. Since the understanding of mechanisms governing mitochondrial dynamics in these tissues is lacking, we investigated the role of OPA1, a mitochondrial fusion protein, in their homeostasis. OPA1 knockdown in NP cells altered mitochondrial size and cristae shape and increased the oxygen consumption rate. OPA1 governed the morphology of multiple organelles, including peroxisomes, early endosomes and cis-Golgi and loss resulted in the dysregulation of autophagy. Metabolic profiling and

Tissue Engineering: History, Principles, Applications, Challenges, And Future Work, Alexa Cesari, Ms

Student Papers, Posters & Projects

Tissue engineering is a comprehensive and cutting-edge field that leverages principles from multiple scientific disciplines to assist in regenerative medicine. It is defined by the most basic structure of the human body, the cell. When an injury occurs, cells send signals to initiate wound healing processes. In most cases, the body is equipped to heal wounds on its own; however, there are instances where wounds are too severe and cannot undergo proper regeneration. When this occurs, alternative measures are taken to assist in wound repair. With numerous advancements made over the years, tissue engineering has become an increasingly common method …

Stress And Seizures: The October 7th Experience, Alon Doron, Firas Fahoum, Lilach Goldstein

Department of Neurology Faculty Papers

Optimizing Costs In Plastic Surgery: A Systematic Review Of Time-Driven Activity-Based Costing Applications, Emily L. Isch, Gabrielle Kozlowski, D. Mitchell Self, Theodore E. Habarth-Morales, Sydney Somers, Ahilan Sivaganesan, David Kim, Heather A. Mcmahon, Andrew Newsman, Matthew Jenkins

Department of Surgery Faculty Papers

BACKGROUND: The rising complexity and cost of healthcare in plastic surgery, particularly in resource-intensive procedures like free flap and breast reconstruction, pose significant financial challenges. Time-driven activity-based costing (TDABC) offers a method to accurately assess these costs by mapping each step of the care cycle based on time and resources consumed. Although TDABC has been utilized in high-cost fields such as neurosurgery and spine surgery, its application in plastic surgery remains underexplored. This systematic review evaluates the literature on TDABC use in plastic surgery to identify key cost drivers and propose strategies for cost-efficiency.

METHODS: A systematic review was conducted …

Small Gifts, Big Questions: The Ethical Dilemma In Accepting Gifts In Medicine, Meiqi Luo, Md

The Medicine Forum

I remember discussing the topic of gift-giving by patients in a small group session in medical school. When asked whether it’s ethical for medical professionals to accept gifts from patients, I responded, “It depends on the value of the gifts.” If the gifts were of appropriate value and given purely out of appreciation, they serve to strengthen the physician-patient relationship. However, what I failed to realize was the difficulty in determining the value and intention of a gift. My personal experience of receiving gifts from a patient made me aware of such ethical ambiguities.

At the community clinic where I …

Navigating Care And Loss Through Aging, Disease, And Decision-Making In The Covid Era, Michael Predi, Do

The Medicine Forum

There is only one of the loved one you know.
Often it can be hard to let go.
Five years old the world became cold.
Lost my mother to breast cancer.
A cold wound that can’t be answered
Father raised you in a foreign land.
Drove you to school, combed your hair, gave you a life you could have never planned.
Taught me that I would catch a cold from the wind.
No arguing about modern medicine, my dad was thick skinned,
Here comes college, first generation, what an exciting time.

Existential Pain, Kian Waddell

The Medicine Forum

A new type of pain
Never covered in a lecture
Not neuropathic, visceral, post-procedural, cancer, phantom pains,
But existential.

She didn’t want pain meds
And she had her reasons -
We didn’t push.

What she wanted was to talk
To be heard
For us to be silent and stop
Asking her every second
If she’d moved bowels, vomited, slept…

What she wanted was to talk.
What other medication is there for pain of the soul?

Eternal Light, Anurag Modak, Md

The Medicine Forum

The microscope is held aloft in a sea of darkness,
Illuminating the gyri and sulci of the exposed brain below.
Its harsh, sterile light creates a veritable barrier
So hot, so intense, it threatens to explode forth at any moment.

The screens scattered across the room provide companionship to this lonely machine
And I, residing amidst the sea of shadows,
Bear witness to its solitude
To the silence of the light.

I have seen vessels tied and aneurysms clipped,
And an eon has gone by…
There’s an air of anticipation,
An expectation of something more.

But, solace and quietude prevail …

Unmasking The Dvt Mimic: A Rare Case Of Diabetic Myonecrosis In A Young Patient, Avish Patel, Md, Paul Endres, Md, Alexander Marchese, Md, Dianna Cheney-Peters, Md

The Medicine Forum

Diabetic myonecrosis is an uncommon complication of diabetes mellitus, often falsely believed to be a deep vein thrombosis (DVT). Patients present with similar presentations of edema and focal tenderness that are most often unilateral in a proximal lower extremity.¹ When venous ultrasound is negative, magnetic resonance imaging (MRI) is the preferred diagnostic modality over muscle biopsy, given the potential complications.^2,3 Treatment includes rest, analgesia, and improved glycemic control.⁴ Given the rise of metabolic disorders and insulin resistance, it is important to be aware of this diagnosis to prevent overutilization of healthcare resources.⁵

Recurrent Post-Viral Rhabdomyolysis In A 36-Year-Old Male: A Case Report, Warda Naqvi, Md, David Walz, Md, Lucy Checchio, Md

The Medicine Forum

Rhabdomyolysis is a syndrome of skeletal muscle breakdown, releasing intracellular contents such as creatine kinase (CK) and myoglobin into the bloodstream, which can precipitate acute kidney injury (AKI).¹ While trauma, extreme exertion, and toxins are frequent culprits, infections, particularly viral illnesses, represent a less common but significant trigger.² Influenza and other respiratory viruses have been implicated in sporadic cases of rhabdomyolysis, often presenting with acute myalgias and elevated CK levels following a viral prodrome.³ In contrast, recurrent rhabdomyolysis is typically associated with inherited metabolic myopathies (e.g., McArdle disease) or autoimmune myositis, conditions often marked by distinct genetic …

Mcconnell’S Sign In The Absence Of Pulmonary Embolism, Alicia Bao, Md, Tendai Marume, Md

The Medicine Forum

McConnell’s sign is an echocardiographic finding characterized by hyperdynamic motion of the right ventricular (RV) apex with akinesis of the RV free wall. It is widely known as an indicator of RV strain in acute pulmonary embolism (PE) but has been described in other conditions such as sepsis-induced RV dysfunction, acute cor pulmonale, and right-sided heart failure. In critically ill patients, RV dysfunction is a major contributor to hemodynamic instability, respiratory failure, and poor outcomes. Given the overlapping signs of various underlying conditions, McConnell’s sign serves as a useful marker for assessing RV involvement but can be challenging to interpret …

Computed tomography (CT) chest demonstrated patchy ground-glass opacities and dense consolidations in the right middle and lower lobe. Blood cultures and bronchoalveolar lavage culture were positive for Streptococcus pneumoniae, and she was started on antibiotics for community-acquired pneumonia. Her respiratory status rapidly worsened and she required intubation. She developed a large right-sided pneumothorax and had a chest tube placed for a …

A Complex Case Of Multifactorial Hypoxemia From Metastatic Testicular Cancer, Susanna Betti, Md

The Medicine Forum

A 27-year-old male with no known past medical history presented for evaluation of a 14.1 cm testicular mass (Figure A). He was found to have severe anemia (Hgb 2.8 g/dL), and biopsy demonstrated a non-seminomatous mixed germ cell tumor of testicular origin with imaging demonstrating widespread metastases to the brain, lungs, and liver. The patient received multiple blood transfusions and one dose of bleomycin, etoposide, and cisplatin followed by the development of acute respiratory failure. Computed tomography angiography (CTA) chest was negative for pulmonary thromboembolism but demonstrated diffuse ground-glass opacities (Figure B, arrows) and metastatic pulmonary masses containing dilated vessels …

Heart Core: A Framework For Leading With Empathy In Medical Education, Akash Patel, Do, Mark Liotta, Md

The Medicine Forum

In medical training, much of what defines leadership happens outside of clinical decision-making. It happens at 2 a.m. when a resident breaks down from burnout. It happens when a team is navigating interpersonal conflict or when a trainee is overwhelmed by grief, imposter syndrome, or failure. While these moments are deeply impactful, many of us are never taught how to lead through them.

This gap inspired us to create HEART CORE, a framework designed to help residents, faculty, and administrators approach complex, emotional, or high-stakes situations with clarity and compassion. Although it was originally built for chief residents handling difficult …
