Research outputs 2022 to 2026

Introduction Breast cancer is the most commonly diagnosed cancer among women worldwide. Survivors often experience physical and psychological effects arising from breast cancer and its treatment, which can last months and years, adversely impacting quality of life. As the number of early breast cancer survivors increases, models of specialist-led follow-up care in hospital settings are not sustainable and evidence suggests that they may not meet survivors’ needs. Nurse-enabled, shared-care, follow-up models between cancer specialist and primary care teams have potential to address this need. Methods and analysis The proposed research is a multicentre, prospective, pragmatic, stepped-wedge cluster-randomised trial designed to …

Inflammation is increasingly recognized as a critical factor in acute myeloid leukemia (AML) pathogenesis. We performed blood-based proteomic profiling of 251 inflammatory proteins in 543 patients with newly diagnosed AML. Using a machine learning model, we derived an 8-protein prognostic score termed the leukemia inflammatory risk score (LIRS). Individual proteins were evaluated in multivariable Cox models, and model performance was assessed by cumulative concordance index. Findings were validated in internal and external cohorts across 2 institutions. Blood-based LIRS significantly outperformed the European LeukemiaNet 2022 risk model and was independently prognostic of overall survival after accounting for known clinical and molecular …

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

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

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 …

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 …

From Er To Mortality In 48 Hours: A Fatal Case Of Overwhelming Post-Splenectomy Infection, Miriam Stern, Ba, Blaise O’Malley, Bs, Amry Majeed, Md, Michael Grodsky, Md

The Medicine Forum

Overwhelming post-splenectomy infection (OPSI) is a known complication of asplenia.^1,2 While the precise rates of morbidity and mortality are unknown, estimates range from 38% to as high as 70%.² Because the spleen plays an important role in protecting against infections with encapsulated microorganisms, OPSI is most commonly caused by infection with encapsulated bacteria, specifically Streptococcus pneumoniae.^1–3 While pneumococcal vaccines have been shown to improve immunogenicity in asplenic people, OPSI remains a danger to both vaccinated and unvaccinated patients.^4,5 Additional measures to protect asplenic patients from overwhelming infection have been proposed, but the evidence remains mixed. …

String Theory - A Case Of Hypermucoviscous Klebsiella Pneumoniae Causing Distant Necrotizing Infections, Natasa Kostic, Md, Marina Gonzalez, Md

The Medicine Forum

Klebsiella pneumoniae is a Gram-negative, encapsulated bacterium belonging to the Enterobacteriaceae family. It is more frequently associated with nosocomial infections and is one of several bacteria developing high rates of antibiotic resistance.¹ Since the mid-1980s, there have been reported cases of Klebsiella pneumoniae causing life-threatening, invasive infections acquired in the community by otherwise healthy individuals. The propensity to form metastatic foci of infection in immunocompetent hosts is unusual for an enteric, Gram-negative pathogen.² This hypervirulent variant of K. pneumoniae was originally noted only in Asian-Pacific countries but is now being identified globally.³ The variant has unique mucoid …

Negative Urine Nucleic Acid Amplification Testing In A Case Of Disseminated Gonococcal Infection Presenting As Migratory Arthritis, Benjamin Richter, Md

The Medicine Forum

Disseminated gonococcal infection (DGI) is a well-documented complication of Neisseria gonorrhoeae infection, most characteristically presenting as migratory arthritis, tenosynovitis, and dermatitis. Although modern nucleic acid amplification tests (NAATs) and cultures from mucosal sites have significantly improved diagnostic capabilities, discrepancies between clinical manifestations and laboratory findings still occur.¹ One such challenge arises when the urine gonorrhea test returns negative despite strong clinical evidence pointing toward gonococcal involvement.

Migratory arthritis—a transient, shifting pattern of joint inflammation—has long been recognized as a hallmark of DGI.² Typically, the pathogen is detected in blood, synovial fluid, or from mucosal specimens; however, negative urine …

A Case Of Varicella Zoster Virus Meningitis Presenting As Idiopathic Vocal Fold Paralysis, Dustin Sneed, Md, M. D. Kilpatrick, Md, Alicia Bao, Md

The Medicine Forum

The typical presentation of a patient with herpes zoster, the reactivation of varicella zoster virus (VZV), involves a painful dermatomal vesicular rash known as shingles. However, as the following case demonstrates, VZV reactivation can present with atypical symptoms, sometimes without the characteristic rash. This presentation is known as zoster sine herpete. This case focuses on a patient presenting with dysphagia and dysphonia, who was diagnosed with VZV meningitis with suspected laryngeal involvement. We discuss workup and treatment for this disease, and the importance of a wide differential and multidisciplinary consultation to improve patient outcomes.

Ifosfamide, an alkylating agent and a cyclophosphamide analog, can be used alone or in combination with other agents as salvage therapy for metastatic soft tissue sarcoma. Neurotoxicity, often presenting as encephalopathy, is a common side effect of ifosfamide therapy, affecting up to 60% of patients.¹ Symptoms can range in severity from mild cognitive disturbances to severe, potentially fatal neurological impairments, such as hallucinations, confusion, drowsiness, and coma, which may develop within 2 to 96 hours of drug administration.²

Treatment of neurotoxicity includes cessation of ifosfamide and initiation of methylene blue (MB), which is used as both a therapeutic …

An Unusual Complication Of Metastatic Colorectal Cancer: Port-Site Hematoma As The First Sign Of Bone Marrow Involvement And Disseminated Intravascular Coagulation, Michael Predi, Do, Julia Palecki, Md, Jordan M. Isaacs, Ba, Ruben Rhoades, Md

The Medicine Forum

Disseminated intravascular coagulation (DIC) is a life-threatening condition marked by a spectrum of thrombosis due to activation of procoagulant factors and bleeding due to eventual consumption of these factors. DIC invariably occurs secondary to an underlying condition, including infection, inflammatory conditions, trauma, and malignancies. Treatment of DIC primarily involves treatment of the underlying cause.¹

Bone marrow invasion occurs when tumor cells infiltrate the hematopoietic marrow space, displacing progenitor cells and causing cytopenias. This process is distinct from bone metastases, where malignant cells spread to the cortical or trabecular bone, typically causing bone pain, pathologic fractures, or hypercalcemia. Disseminated carcinomatosis …

Case Report Of Gastritis As A Complication Of Immunotherapy Treatment Of Metastatic Endometrial Cancer With Lenvatinib And Pembrolizumab, Bret Mccarty, Md, Nia Johnson, Bs, Suchit Bhutani, Md

The Medicine Forum

Immune checkpoint inhibitors (ICIs), such as pembrolizumab (a PD-1 inhibitor), have been shown to be effective in the treatment of a variety of malignancies, including progressive endometrial cancer. ICIs help to activate the patient’s immune system to attack neoplastic cells. However, this immune activation can trigger autoimmune side effects throughout the body, known as immune-related adverse events (irAEs). Immunotherapyassociated hepatitis, colitis and diarrhea have been well documented as irAEs, but gastritis is much less common.1 In this case report of immunotherapy-related gastritis, we attempted to better characterize this more rare condition to assist with early recognition and initiation of appropriate …
