Underrepresented populations are often excluded from genomic studies owing in part to a lack of resources supporting their analyses. The 1000 Genomes Project (1kGP) and Human Genome Diversity Project (HGDP), which have recently been sequenced to high coverage, are valuable genomic resources because of the global diversity they capture and their open data sharing policies. Here, we harmonized a high-quality set of 4094 whole genomes from 80 populations in the HGDP and 1kGP with data from the Genome Aggregation Database (gnomAD) and identified over 153 million high-quality SNVs, indels, and SVs. We performed a detailed ancestry analysis of this cohort, …

Hypoxia Inducible Factor 2Α Promotes Tolerogenic Macrophage Development During Cardiac Transplantation Through Transcriptional Regulation Of Colony Stimulating Factor 1 Receptor, Matthew Deberge, Samantha Schroth, Fanfan Du, Xin Yi Yeap, Jiao-Jing Wang, Zheng Jenny Zhang, Mohammed Javeed Ansari, Evan A Scott, Edward B Thorp

Faculty, Staff and Student Publications

Solid organ transplantation mobilizes myeloid cells, including monocytes and macrophages, which are central protagonists of allograft rejection. However, myeloid cells can also be functionally reprogrammed by perioperative costimulatory blockade to promote a state of transplantation tolerance. Transplantation tolerance holds promise to reduce complications from chronic immunosuppression and promote long-term survival in transplant recipients. We sought to identify different mediators of transplantation tolerance by performing single-cell RNA sequencing of acute rejecting or tolerized cardiac allografts. This led to the unbiased identification of the transcription factor, hypoxia inducible factor (HIF)-2α, in a subset of tolerogenic monocytes. Using flow cytometric analyses and mice …

Cracd Loss Induces Neuroendocrine Cell Plasticity Of Lung Adenocarcinoma, Bongjun Kim, Shengzhe Zhang, Yuanjian Huang, Kyung-Pil Ko, Youn-Sang Jung, Jinho Jang, Gengyi Zou, Jie Zhang, Sohee Jun, Kee-Beom Kim, Kwon-Sik Park, Jae-Il Park

Faculty, Staff and Student Publications

Tumor cell plasticity contributes to intratumoral heterogeneity and therapy resistance. Through cell plasticity, some lung adenocarcinoma (LUAD) cells transform into neuroendocrine (NE) tumor cells. However, the mechanisms of NE cell plasticity remain unclear. CRACD (capping protein inhibiting regulator of actin dynamics), a capping protein inhibitor, is frequently inactivated in cancers. CRACD knockout (KO) is sufficient to de-repress NE-related gene expression in the pulmonary epithelium and LUAD cells. In LUAD mouse models, Cracd KO increases intratumoral heterogeneity with NE gene expression. Single-cell transcriptomic analysis showed that Cracd KO-induced NE cell plasticity is associated with cell de-differentiation and stemness-related pathway activation. The …

A Spatiotemporal Map Of Co-Receptor Signaling Networks Underlying B Cell Activation, Katherine J Susa, Gary A Bradshaw, Robyn J Eisert, Charlotte M Schilling, Marian Kalocsay, Stephen C Blacklow, Andrew C Kruse

Faculty, Staff and Student Publications

The B cell receptor (BCR) signals together with a multi-component co-receptor complex to initiate B cell activation in response to antigen binding. Here, we take advantage of peroxidase-catalyzed proximity labeling combined with quantitative mass spectrometry to track co-receptor signaling dynamics in Raji cells from 10 s to 2 h after BCR stimulation. This approach enables tracking of 2,814 proximity-labeled proteins and 1,394 phosphosites and provides an unbiased and quantitative molecular map of proteins recruited to the vicinity of CD19, the signaling subunit of the co-receptor complex. We detail the recruitment kinetics of signaling effectors to CD19 and identify previously uncharacterized …

A Case Report Of Acute Idiopathic Hepatitis Requiring Liver Transplant, Nathan Rim, Nevin Varghese, Md, Zachary Pang, Md

The Medicine Forum

Acute liver injury may be very difficult to treat, especially when the etiology is unknown. We describe a case of a patient who presented with signs and symptoms of acute liver injury and went through an extensive work-up that did not reveal a definitive cause. The lack of diagnosis can be distressing for the patient, so it is important to regularly communicate the current plan and potential future necessary steps (such as a transplant surgery) to facilitate smooth, informed decision-making throughout the whole process.

A Rare Case Of Upper Gastrointestinal Bleeding And Esophageal Candidiasis In Severe Achalasia, Nevin Varghese, Md, Bertilia Tavárez, Md, Justin Robbins, Md

The Medicine Forum

Achalasia is an esophageal dysmotility disorder characterized by failure of relaxation of the lower esophageal sphincter (LES), accompanied by aperistalsis of the distal esophagus. Recent data show that the prevalence of achalasia in the United States is 10 per 100,000 individuals.¹ Complications of achalasia include esophagitis, esophageal ulcer, esophagealtracheal fistula, esophageal rupture, aspiration pneumonia, and squamous cell carcinoma. We report a rare case of upper gastrointestinal bleeding associated with esophageal ulcer and candidiasis in a patient with severe achalasia requiring multiple endoscopic interventions.

Bicuspid Aortic Valve With Right Coronary Cusp And Noncoronary Cusp Fusion On Transesophageal Echocardiogram, Kashka Mallari, Md

The Medicine Forum

A 39 year old male with a bicuspid aortic valve (BAV) developed progression of aortic valve regurgitation and enlargement of the ascending aorta, despite showing no symptoms. BAV, affecting approximately 2% of the population, poses risks such as aortic stenosis, aortic regurgitation, endocarditis, and aortic dilation, which can lead to aortic aneurysm and potential rupture. Due to the risk of further progression, he underwent a trans-esophageal echocardiogram (TEE) to facilitate aortic valve repair. While majority of patients with BAV exhibit fusion between the right coronary cusp (RCC) and left coronary cusp (LCC), this patient displayed fusion between the RCC and …

Hypertrophic Cardiomyopathy Illustrated On A Transthoracic Echocardiogram And Cardiac Mri, Youssef Elfatatry, Md, Marina Gonzalez, Md

The Medicine Forum

A 46-year-old woman presented to the hospital with subacute dyspnea on exertion and syncope. She had three syncopal episodes in the months prior, all of which occurred after standing from seated position and were associated with complete loss of consciousness. Echocardiogram showed severe concentric left ventricular hypertrophy (LVH) with preserved systolic function (Panels A and B). Cardiac magnetic resonance (CMR) imaging was performed which confirmed asymmetric septal hypertrophy measuring 28-mm in thickness (Panel C, arrow). Patchy, late gadolinium enhancement was also seen within the myocardium (Panel D, arrows). A diagnosis of hypertrophic cardiomyopathy (HCM) was made. The patient had no …

Wellens' Syndrome On Electrocardiogram, A Highly Specific Indicator Of Critical Stenosis Of The Left Anterior Descending Coronary Artery, Youssef Elfatatry, Md, Ryan Gardner, Md

The Medicine Forum

An 85-year-old male with a past medical history of hyperlipidemia presented to his primary care physician with chest pain. The patient had experienced an acute episode of substernal chest pain that resolved spontaneously three days prior to presentation. An electrocardiogram (ECG) was obtained in the office which showed inverted and biphasic T-waves throughout the precordial chest leads (Panel A, arrows). The patient was sent to the emergency department and underwent an emergent cardiac catheterization which revealed a 99% proximal left anterior descending (LAD) artery occlusion (Panel B, arrow). A drug-eluting stent was placed with successful revascularization (Panel C, arrow). Wellens …

Investigating The Etiology Of Non-Ischemic Cardiomyopathy; A Case Report Of Cardiac Amyloidosis, Zachary Pang, Md, Joshua M. Riley, Md, Yair Lev, Md

The Medicine Forum

Amyloidosis is the result of misfolded protein deposition in organs and tissues, including the heart also known as cardiac amyloidosis. We describe a case of a patient presenting with decompensated heart failure, which highlights the importance of identifying the etiology of the patient’s cardiomyopathy through a thorough history and physical. This led to a diagnosis of cardiac amyloidosis. The patient was subsequently initiated on tafamidis, a medication that is associated with reductions in all-cause mortality and cardiovascular-related hospitalizations, reduced decline in functional capacity, and improved quality of life of the patient.

Laao Device Mass: A Classic Condition Involving A Not - So - Classic Device, Ryan Gardner, Md, Rabia Naheed, Md, Youssef Elfatatry, Md, Irfan Ahsan, Md, Alyson N. Owen, Md

The Medicine Forum

Current evidence suggests Class 2a recommendation for a left atrial appendage occlusion with a closure device in patients with atrial fibrillation who have moderate to high risk of stroke (CHA2DS2-VASc score ≥2) and a contraindication to long-term oral anticoagulation due to a nonreversible cause.¹ Watchman device (WD) related infection is infrequent due to complete endothelialization of the device in a few weeks.² We report a highly challenging case of possible WD-related infection that involved complex decision-making.

Dissecting The Literature: A Systematic Review Of Conservative Therapy Versus Revascularization In Spontaneous Coronary Artery Dissection, Avinash Saraiya, Ms, Brian Schonewald, Md

The Medicine Forum

Spontaneous coronary artery dissection (SCAD) is a rare, but increasingly recognized cause of acute coronary syndrome (ACS). While previously only described in case series, the advent of advanced imaging techniques such as intravascular ultrasound (IVUS) and optical coherence tomography (OCT) has increased its prevalence dramatically. Anatomically, SCAD results from the formation of an intramural hematoma with or without intimal tear in a coronary artery, potentially leading to occlusion and ischemia. This phenomenon is especially common in women, accounting for 35% of ACS in women under the age of 50, and representing the leading cause of peripartum myocardial infarct.¹ There …

Rothman Institute Papers

INTRODUCTION: Revision lumbar fusion is most commonly due to nonunion, adjacent segment disease (ASD), or recurrent stenosis, but it is unclear if diagnosis affects patient outcomes. The primary aim of this study was to assess whether patients achieved the patient acceptable symptom state (PASS) or minimal clinically important difference (MCID) after revision lumbar fusion and assess whether this was influenced by the indication for revision.

METHODS: We retrospectively identified all 1-3 level revision lumbar fusions at a single institution. Oswestry Disability Index (ODI) was collected at preoperative, three-month postoperative, and one-year postoperative time points. The MCID was calculated using a …

Postnatal Corticosteroid Therapy In Bronchopulmonary Dysplasia - Why Animal Studies Disagree With Clinical Trials?, Anantha Harijith, Thomas M. Raffay, Rita M. Ryan

Faculty Scholarship

Abstract: The systematic review and meta-analysis of newborn animal models by Irene Lok et al. is the first to extensively summarize the literature regarding postnatal systemic corticosteroid use on lung development of newborn rodent models. The meta-analysis showed that the use of postnatal corticosteroids resulted in a reduction in body weight along with persistent alveolar simplification. The most frequently used corticosteroid was dexamethasone. Corticosteroids have been extensively used in clinical trials in preterm newborns. Trials using early systemic administration of corticosteroids reduced the rate of BPD or mortality with no increase in the rates of cerebral palsy. Use of late …

Neuroimaging Of Vermiform Giant Arachnoid Granulations In Children, Oswaldo A Guevara Tirado, Livja Mertiri, Stephen F Kralik, Nilesh K Desai, Thierry A G M Huisman, Maarten H Lequin, Huy Brandon D Tran

Faculty, Staff and Students Publications

Arachnoid granulations (AGs) are generally benign structures within the subarachnoid space that extend into the dural sinuses and calvarial bone. They can present in a variety of sizes but are termed 'giant' arachnoid granulations (GAGs) when they are larger than 1 cm in diameter or take up a significant portion of the dural sinus' lumen. Vermiform giant arachnoid granulations are a specific type of GAG that are known for their worm-like appearance. Specifically, these vermiform GAGs can be challenging to diagnose as they can mimic other pathologies like dural sinus thrombosis, sinus cavernomas, or brain tumors. In this case series, …

BACKGROUND: Tau is aberrantly acetylated in various neurodegenerative conditions, including Alzheimer's disease, frontotemporal lobar degeneration (FTLD), and traumatic brain injury (TBI). Previously, we reported that reducing acetylated tau by pharmacologically inhibiting p300-mediated tau acetylation at lysine 174 reduces tau pathology and improves cognitive function in animal models.

METHODS: We investigated the therapeutic efficacy of two different antibodies that specifically target acetylated lysine 174 on tau (ac-tauK174). We treated PS19 mice, which harbor the P301S tauopathy mutation that causes FTLD, with anti-ac-tauK174 and measured effects on tau pathology, neurodegeneration, and neurobehavioral outcomes. Furthermore, PS19 mice received treatment post-TBI to evaluate the …

Tumor Biomechanical Stiffness By Magnetic Resonance Elastography Predicts Surgical Outcomes And Identifies Biomarkers In Vestibular Schwannoma And Meningioma, Bailey H Duhon, Kristin Thompson, Melanie Fisher, Vivian F Kaul, Han Tn Nguyen, Michael S Harris, Varun Varadarajan, Oliver F Adunka, Daniel M Prevedello, Arunark Kolipaka, Yin Ren

Faculty, Staff and Student Publications

Variations in the biomechanical stiffness of brain tumors can not only influence the difficulty of surgical resection but also impact postoperative outcomes. In a prospective, single-blinded study, we utilize pre-operative magnetic resonance elastography (MRE) to predict the stiffness of intracranial tumors intraoperatively and assess the impact of increased tumor stiffness on clinical outcomes following microsurgical resection of vestibular schwannomas (VS) and meningiomas. MRE measurements significantly correlated with intraoperative tumor stiffness and baseline hearing status of VS patients. Additionally, MRE stiffness was elevated in patients that underwent sub-total tumor resection compared to gross total resection and those with worse postoperative facial …

Clinical And Genomic Profile Of Primary Cranial Neurolymphomatosis, Emily B Wolf, Robin Imperial, Liuyan Jiang, Amit K Agarwal, Han W Tun

Faculty, Staff and Student Publications

Primary cranial neurolymphomatosis (PCNL) is a rare subtype of primary CNS lymphoma (PCNSL) in which infiltrative lymphomatous involvement is confined to cranial nerves. Here, we report a case of PCNL with successful genomic profiling. A 57-year-old male had a lengthy prediagnostic phase spanning approximately 30 months, characterized by multiple episodes of cranial neuropathies managed by steroids. At the time of diagnosis, the patient had right-sided cranial neuropathies involving cranial nerves (CN) V, VI, and VII. Pathological findings of the right cavernous lesion biopsy were consistent with large B-cell lymphoma-infiltrating nerve fibers. The clinical course was aggressive and refractory, characterized by …
