The metabolic importance of brown adipose tissue (BAT) has been recognized, but its origins, particularly supraclavicular BAT (scBAT), remain unclear. Here, we traced scBAT to Mef2c-anterior heart field (AHF)-marked cells. Mef2c-AHF-marked cells isolated from scBAT can spontaneously differentiate into brown adipocytes, express mesenchymal stem cell markers, and can be isolated from the stromal-vascular fraction (SVF) of wild-type scBAT as [CD31

Journal of the Saudi Heart Association

Background: Cardiovascular, kidney, metabolic, and liver diseases are closely interconnected and frequently coexist. While the cardiovascular–kidney–metabolic (CKM) framework provides a unified model, increasing evidence supports a central role for hepatic disease, particularly metabolic dysfunction–associated steatotic liver disease (MASLD), in this continuum. The Saudi Heart Association (SHA) therefore aimed to introduce the cardiovascular–kidney–liver–metabolic (CKLM) syndrome as an expanded framework and provide expert guidance on its pathophysiology, staging, screening, and management, with relevance to the Saudi population.

Methods: A multidisciplinary expert panel convened under the auspices of the SHA conducted a comprehensive, non-systematic literature review and developed consensus-based recommendations through iterative discussion …

Definitive Radiation Therapy For Schneiderian Inverted Papilloma Of The Soft Palate And Uvula., Rahul Sinha, Arianne J Abreu, Christopher E Fundakowski, Robert T Sataloff

Otolaryngology (ENT) Resident Research

Schneiderian inverted papilloma is a benign, locally aggressive tumor that typically arises in the respiratory mucosa of the nasal cavity and paranasal sinuses. These tumors are often asymptomatic but can cause unilateral nasal obstruction, discharge, hyposmia and epistaxis. They warrant attention particularly due to the potential for malignant transformation. They are treated most often with surgical excision. This case report describes a patient with Schneiderian inverted papilloma arising outside its usual location and managed with definitive radiation therapy instead of surgical excision due to concerns for functional impairment. Remission was obtained with radiation therapy, although the patient experienced treatment-related side …

Faculty, Staff and Students Publications

Admixed individuals have been understudied in medical research largely due to their complex genetic ancestries. However, the consideration of admixture can identify ancestry-enriched genetic associations, delineating genetic underpinnings of cross-population phenotypic variation. Here, we performed admixture mapping in individuals with inferred admixture from African and European populations (N = 48,921). Across 22 traits, we identified 71 ancestry-trait associations, including loci where ancestral haplotypes explained phenotypic variation yet were missed by single-variant association testing due to their stricter multiple testing burden. One such locus where inferred local AFR ancestries are associated with increased hemoglobin A1c (HbA1c) was 12q14.3, highlighting its potential …

Dosimetric Comparison Between Geometric Centroid And Minimax Isocenter Placement In Single Isocenter Multitarget Stereotactic Radiosurgery Plans In Hyperarc, Matthew Gloudeman

Masters Projects

Single-isocenter multi-target (SIMT) stereotactic radiosurgery (SRS) utilizing Varian HyperArc streamlines clinical workflows but introduces geometric sensitivity for distant outlier lesions when rotational and setup uncertainties are taken into account. The default isocenter location in the HyperArc workspace is the geometric centroid, which is inherently biased toward clusters of lesions. This study evaluates the dosimetric plan quality of an alternative minimax isocenter strategy, which minimizes the maximum lesion-to-isocenter distance, shortening the rotational lever arm to enhance mechanical robustness. Two fractionated SRS (fSRS) plans were generated for ten patients with 3-5 brain metastases using identical beam configurations: one using HyperArc’s default geometric …

A Clinical Accuracy Study Protocol For A Saliva-Based Point-Of-Care Lateral Flow Test To Assess Protective Immunity To Tetanus (Tetanus Study), H F Kwok, R Agarwal, Y Takwoingi, Semukunzi H, C Umuhoza, A Richter, J Nyombayire, C M Muvunyi, J Heaney, C A Green

Faculty, Staff and Students Publications

Introduction: Despite the availability of a safe and effective vaccine, 2000-3000 neonates die of tetanus yearly, predominantly in low- to middle-income countries (LMICs). Inaccurate coverage estimates and vaccination records, together with variability in vaccine response, make identifying individuals who lack protective immunity and may benefit from vaccination difficult. A more direct measure of protective immunity is widely accepted as anti-tetanus IgG concentration at or above 0.1 IU/mL. This study aims to evaluate the performance of a novel saliva-based point-of-care lateral flow test (CIS-IMMUNE Tet) for the binary classification of tetanus protective immune status (protected/unprotected) against WHO threshold-based classification of IgG …

Manuscripts, Articles, Book Chapters and Other Papers

BACKGROUND: Pediatric cancer treatment is a difficult and distressing experience that often results in sustained, interrelated distress in young children and parents, and traumatic stress symptoms for some parents. Few evidence-based interventions address this dyadic distress. Active Music Engagement (AME) is a manualized, evidence-based music play intervention that significantly reduces distress in child/parent dyads and mitigates traumatic stress and improves well-being among highly distressed parents and those experiencing sociodemographic risk. Successfully integrating AME into standard care requires a systematic understanding of implementation factors. This study aimed to identify site-specific barriers and facilitators that influenced successful AME delivery during a recently …

Faculty, Staff and Students Publications

Mutations in the transcription factor gene Wilms Tumor 1 (WT1) are one of the leading causes of congenital glomerular disease, characterized by severe urinary protein loss and glomerular scarring. No disease-modifying therapies exist for WT1 glomerulopathies, and affected children rely on dialysis or kidney transplantation. We evaluated a previously uncharacterized treatment in a mouse model with an orthologous human mutation in Wt1 (Wt1+/R394W) that replicates the pathology of WT1 glomerulopathy. Lipid nanocomplexes were engineered to target integrin αvβ3 for efficient delivery of mRNA to primary podocytes and glomerular endothelial cells in vitro. A minimally …

A Rare Sight: Isolated Third Nerve Palsy As The Sole Presentation Of A Non-Functional Pituitary Adenoma, Jorge A. Aboytes, Jose J. Loayza, Ivan Mogollon, Ismael Cantu

Research Colloquium

Introduction: Hypopituitarism results from insufficient pituitary hormone production, often due to adenomas—accounting for ~15% of intracranial tumors. Non-functional adenomas, typically affecting older adults, may present with visual field deficits, headaches, or cranial nerve palsies when extending into the cavernous sinus. Isolated oculomotor (third nerve) palsy is a rare initial manifestation.

Case: A 46-year-old man with uncontrolled type 2 diabetes presented with acute right-sided headache, diplopia, ptosis, and right leg weakness. He had right ptosis, a fixed dilated pupil, facial droop, and right leg weakness. Given concern for stroke, he received thrombolytic therapy with partial leg improvement, but persistent diplopia and …

Research Colloquium

Introduction: Deep vein thrombosis (DVT) in young adults is uncommon and typically associated with identifiable risk factors. In cases where DVT occurs without apparent provocation, congenital anatomical anomalies should be considered. May-Thurner Syndrome (MTS), a vascular compression disorder involving the left iliac vein, is a frequently overlooked cause of iliofemoral DVT in young individuals, particularly women.

Case Presentation: A 28-year-old woman with no significant medical history presented with acute left leg swelling, pain, and discoloration, along with new-onset dyspnea and chest discomfort. She had recently transitioned to a contraceptive patch and reported reduced mobility due to fatigue. Imaging confirmed left …

Fatigue And Circadian Disruption In Long-Haul Ferry Pilots: Human Factors Challenges And Mitigation Strategies, Parneet Makkar

Discovery Day - Daytona Beach

Fatigue and circadian rhythm disruption present significant human factors challenges in long-haul aviation operations, particularly for ferry pilots (pilots responsible for transporting aircraft long distances between locations) who often travel across multiple time zones before beginning flight duties. Circadian rhythms regulate the human sleep-wake cycle and are closely tied to cognitive performance, alertness, and coordination. Rapid travel across time zones can disrupt these rhythms, producing symptoms commonly associated with jet lag such as sleep disturbances, fatigue, and reduced cognitive functioning. For ferry pilots, long travel periods and irregular schedules may increase the likelihood of fatigue before flight operations even begin. …

Implementation Of Artificial Intelligence In Retinoblastoma Diagnosis, Zana Moldavsky

inSIGHT

The retina is essential for vision. It is composed of 10 distinct layers and contains specialized photoreceptor cells, rods, and cones that are responsible for converting photons of light into electrical signals through a process called phototransduction.¹ These electrical signals are transmitted to the brain via the optic nerve where they are interpreted as a visual picture.¹

Retinoblastoma is a rare but aggressive malignant tumor of the retina and represents the most common intraocular malignancy in the pediatric populabon.² The disease follows Knudson's two-hit hypothesis and occurs due to biallelic inactivation of the RB1 tumor suppressor gene …

Home-Use Oct For Neovascular Age-Related Macular Degeneration: A Rapid Review, Sneh S. Shah

inSIGHT

Neovascular age-related macular degeneration (nAMD) requires frequent monitoring to identify recurrent exudation and guide treatment with anti-vascular endothelial growth factor (VEGF) therapy.1 Clinic-based optical coherence tomography (OCT) plays a central role in management but provides only intermittent assessments of a disease that changes over time. Home-use OCT technologies have recently been developed as a possible solution, allowing patients to perform self-imaging with remote clinician review and artificial intelligence (AI)-assisted analysis. This rapid review summarizes current evidence on home-use OCT for nAMD, including feasibility, diagnostic performance, clinical usefulness, and challenges related to implementation. Findings from feasibility studies, AI validation analyses, observational …

inSIGHT

Glucagon-like peptide-1 receptor agonists (GLP-1 RAs) have moved from second-line diabetes medications toward the frontline of type 2 diabetes, obesity, and cardiometabolic care.¹ A meta-analysis of 10 randomized cardiovascular outcomes trials (n = 71,351) demonstrated that longacting GLP-1 RAs reduce major adverse cardiovascular events by 14%, all-cause mortality by 12%, and composite kidney outcomes by 17%.² With GLP-1 RAs usage increasing, ophthalmology is also increasingly encountering patients who have recently started GLP-1 RAs therapy, often alongside substantial improvements in glycemic control.

In the context of GLP-1 RAs ocular complications, two specific topics currently dominate conversations: (1) worsening diabetic …

Dichoptic Therapy Versus Patching – State Of Literature Review, Eve Miller

inSIGHT

Amblyopia is the most common cause of vision loss in children. A meta-analysis performed by Hu et al. 2022 estimated the global prevalence of amblyopia to be 1.36%.¹ Amblyopia is defined as a reduction in best-corrected visual acuity (BCVA) of one or both eyes caused by abnormal neurologic development in the critical period of visual development. Amblyopia may result from unequal refractive error, strabismus or ocular pathology.² Despite treatment of these inciting factors, suppression of one eye remains, resulting in unequal vision. The clinical consequences of untreated amblyopia include permanent reduction in vision in the affected eye and …

Novel Advancements In Glaucoma Surgery, Eshani Ragam

inSIGHT

Glaucoma is a degenerative ocular condition characterized by irreversible vision loss from damage to the optic nerve. This is usually secondary to increased aqueous production or impaired aqueous outflow, resulting in increased intraocular pressure (IOP). Aqueous outflow is managed by the trabecular meshwork and Schlemm’s canal, although secondary pathways may also be involved.¹ Injury to the nerve is permanent, and interventions are primarily aimed at slowing the rate of progression. While eye drops and laser procedures are first-line measures to lower IOP, more persistent or severe etiologies require surgical treatment to preserve sight.² In recent years, advancements in …

Novel Treatments For Keratoconus, Caroline Paik

inSIGHT

Keratoconus is a progressive condition in which the cornea gradually thins and bulges outward, causing it to become steep and irregular. This leads to irregular astigmatism and worsening vision, most often beginning in adolescence or early adulthood.¹ The management of keratoconus has evolved significantly over the past two decades, with novel therapeutic approaches emerging across three critical domains: halting disease progression, improving visual function, and providing surgical alternatives when conservative measures fail. This review examines the latest advances in keratoconus treatment, focusing on innovative approaches that are reshaping clinical practice.

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND: Avascular necrosis (AVN) of the humeral head often affects younger patients and may lead to progressive pain and functional deficits. While stemmed hemiarthroplasty and total shoulder arthroplasty (TSA) are established treatments for advanced-stage AVN, stemless arthroplasty offers potential advantages including bone preservation and facilitation of future revision. However, the impact of bone necrosis on stemless humerus fixation is yet to be elucidated. Therefore, the purpose of this study was to evaluate the outcomes of stemless hemiarthroplasty and TSA in treating humeral head AVN and, further, to determine if stemless humeral fixation is appropriate in this population.

METHODS: This retrospective …
