While the early effects of the COVID-19 pandemic on the United States labor market are well-established, less is known about the long-term impact of SARS-CoV-2 infection and Long COVID on employment. To address this gap, we analyzed self-reported data from a prospective, national cohort study to estimate the effects of SARS-CoV-2 symptoms at three months post-infection on missed workdays and return to work. The analysis included 2,939 adults in the Innovative Support for Patients with SARS-CoV-2 Infections Registry (INSPIRE) study who tested positive for their initial SARS-CoV-2 infection at the time of enrollment, were employed before the pandemic, and completed …

Methadone maintenance treatment for opioid dependent mothers is standard of care. Infants of methadone maintained opioid dependent (MMOD) mothers have better outcomes compared to infants of opioid dependent mothers without treatment. However, when compared to non-exposed infants, infants of MMOD mothers are associated with worse outcomes. We conducted a pilot study to examine genome wide differential DNA methylation using cord blood samples from sixteen term and near-term infants of MMOD and opioid naïve mothers, excluding Infants with chorioamnionitis. A total of 152 differentially methylated loci were identified at a difference >  + 2, < - 2 and p-value < 0.05. There were 90 hypermethylated loci (59 annotated genes) and 62 hypomethylated loci (38 annotated genes) observed. The hypermethylated and hypomethylated DNA changes involved multiple genes, pathways and networks that may explain some of the changes seen in infants of MMOD mothers. Top hypermethylated and hypomethylated genes involved areas of cell growth, neurodevelopment, vision and xenobiotic metabolism functions. Our data may explain the role of key pathways and genes relevant to neonatal outcomes seen from methadone exposure in pregnancy. Functional studies on the identified pathways and genes could lead to improved understanding of the mechanisms and identify areas for intervention.

Global Burden Of Five Major Types Of Gastrointestinal Cancer, Arjun Singh

Division of Gastroenterology and Hepatology Faculty Papers

Gastrointestinal (GI) cancers cause major global morbidity and mortality, with over 5 million new cases and 3.5 million deaths in 2020. The most prevalent GI malignancies are colorectal, gastric, liver, oesophageal, and pancreatic cancers. Marked geographic variations exist, with high incidence in developed regions contrasting with high mortality in developing areas. These patterns reflect disparities in risk factors and cancer control capacities. However, GI cancer incidence is rising with economic growth and lifestyle changes. Poor prognosis and increasing burden underscore the critical need for expanded prevention and research. This review examines global epidemiology, risks, prevention, detection, treatment, and priorities for …

Impact Of Tumor Pigmentation In 6934 Patients With Uveal Melanoma At A Single Center, Samuel Goldstein, Ferris Bayasi, George Thomas, Matthew Barke, Michael Nguyen, Samantha Pastore, Carol Shields

Wills Eye Hospital Papers

Purpose: To evaluate clinical features and outcomes associated with degree of tumor pigmentation in patients with uveal melanoma (UM) of the choroid and ciliary body. Design: Retrospective observational study. Subjects: Six thousand nine hundred thirty-four consecutive patients with choroidal or ciliary body melanoma between 1971 and 2007 from a single ocular oncology center. Methods: Data on patient demographics, tumor characteristics, treatment approach, and clinical outcomes were collected. Comparisons between pigmented (>80% pigmentation by surface area), partially pigmented (20%–80%), and nonpigmented tumors (<20%) were performed using relevant hypothesis testing. Survival analyses for metastasis and melanoma-related death were conducted using the Kaplan–Meier method with log-rank tests for univariate comparisons. A multivariate Cox regression analysis was performed to assess the independent effects of multiple covariates on time-to-metastasis. Main Outcome Measures: Extraocular extension, ocular melanocytosis, time to tumor recurrence, tumor location, and melanoma-related metastasis and death. Results: There were 6934 eyes with UM and the degree of tumor pigmentation was classified as pigmented (n = 3762; 54%), partially pigmented (n = 2115; 31%), or nonpigmented (n = 1057; 15%). Pigmented UM was associated with extraocular extension (P < 0.001), ocular melanocytosis (P = 0.003), earlier tumor recurrence (P < 0.001), and more anterior tumor epicenter location (ciliary body, and equator to ora serrata) (P < 0.001). Pigmented UMs also exhibited the highest 10-year metastasis rate at 26%, compared with 19% for partially pigmented UMs and 16% for nonpigmented UMs (P < 0.001). Kaplan–Meier survival curves demonstrated differences among the tumor pigmentation groups for melanoma-related metastasis (P < 0.001) and melanoma-related death (P < 0.001). Multivariate Cox regression analysis for melanoma-related metastasis showed that pigmented UMs had a 29% higher relative risk of developing metastasis compared with partially pigmented UMs (P = 0.002) and a 54% higher relative risk of developing metastasis compared with nonpigmented UMs (P < 0.001). Conclusions: Pigmented choroidal and ciliary body melanoma is more often associated with ocular melanocytosis, extraocular extension, anterior tumor epicenter, and earlier tumor recurrence. We also revealed that patients with pigmented UMs demonstrate a higher 10-year rate of metastatic disease and have decreased metastatic survival relative to partially pigmented and nonpigmented UMs. Financial Disclosures: Proprietary or commercial disclosure may be found in the Footnotes and Disclosures at the end of this article.

Setting Up An Ambulatory Gi Endoscopy Suite In The Usa-Anesthesia And Sedation Challenges, Basavana Goudra

Department of Anesthesiology Faculty Papers

Gastrointestinal endoscopy units, both freestanding and associated with ambulatory surgical centers, are on the increase, and the trend is likely to continue. The concept is relatively new, and there are insufficient guidelines and a general dearth of information for prospective planners and physicians. Debate continues in areas such as the selection of patients, appropriateness of procedures, and access to tertiary care. Leaders often scramble to address both critical and non-critical issues, often after the center has opened to the public. They often encounter issues which were not anticipated. In this review, we have provided comprehensive and concise information on the …

Genome-Wide Methylation Patterns In Primary Uveal Melanoma: Development Of Methylsig-Um, An Epigenomic Prognostic Signature To Improve Patient Stratification, Emilie Lalonde, Dong Li, Kathryn Ewens, Carol L. Shields, Arupa Ganguly

Wills Eye Hospital Papers

Despite studies highlighting the prognostic utility of DNA methylation in primary uveal melanoma (pUM), it has not been translated into a clinically useful tool. We sought to define a methylation signature to identify newly diagnosed individuals at high risk for developing metastasis. Methylation profiling was performed on 41 patients with pUM with stage T2-T4 and at least three years of follow-up using the Illumina Infinium HumanMethylation450K BeadChip (N = 24) and the EPIC BeadChip (N = 17). Findings were validated in the TCGA cohort with known metastatic outcome (N = 69). Differentially methylated probes were identified in patients who developed …

Remimazolam And Its Place In The Current Landscape Of Procedural Sedation And General Anesthesia, Matthew Brohan, Janette Brohan, Basavana Goudra

Department of Anesthesiology Faculty Papers

Remimazolam was derived from its parent compound by adding an ester linkage into its structure so that the drug becomes a substrate for ester metabolism. As a result, it undergoes organ-independent ester hydrolysis, although the clinical benefits in terms of shorter recovery are not uniformly observed in clinical practice. Remimazolam is mainly tested in procedural sedation. In comparison to propofol, the current gold standard for procedural sedation, its proposed attractiveness is shorter wake-up times and a clear-headed recovery. Its clear advantages over propofol are better hemodynamic stability, lack of pain on injection and availability of a reversal agent in the …

Kimmel Cancer Center Papers, Presentations, and Grand Rounds

Recent evidence suggests that the descending modulatory pathways from the brainstem rostral ventromedial medulla (RVM) are important for bladder inflammatory pain. This study aimed to identify the long-term molecular changes in RVM neurons due to early life cystitis during neuronal development and the effect of reexposure later in adulthood. RVM tissues from two treatment protocols were used: (1) neonatal zymosan exposures with acute adult rechallenge (RC) and (2) only neonatal zymosan exposures (NRC). RNAseq analysis showed upregulation of several genes associated with synaptic plasticity (Grin1, Grip2, Notch1, Arc, and Scn2b) in the cystitis groups compared to controls in both protocols. …

Assessing Pharmacy Budget Impact Of Tirzepatide For Weight Loss: A U.S. Commercial Payer Perspective, Christopher J. Bigness, Pharmd, Bcps

Master of Science in Applied Health Economics and Outcomes Research Capstone Presentations

Obesity has emerged as a significant health concern, with increasing prevalence rates impacting morbidity and mortality. In recent years, the FDA has approved several medications for weight management, including phentermine/topiramate, bupropion/naltrexone, liraglutide, and semaglutide. Despite the availability of various prescription weight loss medications, their real-world effectiveness remains uncertain. In November 2023, a new promising injectable medication, tirzepatide, received FDA approval to treat obesity. This study investigates the potential pharmacy budget impact of tirzepatide into a U.S. commercial pharmacy benefit plan for an employer group with 10,000 adult members over a 5-year time horizon. The model encompasses all injectable weight loss …

Dna Fork Remodeling Proteins, Zranb3 And Smarcal1, Are Uniquely Essential For Aging Hematopoiesis, Saul Kushinsky, Matthew V. Puccetti, Clare M. Adams, Irina Shkundina, Nikkole James, Brittany M. Mahon, Peter Michener, Christine M. Eischen

Department of Pharmacology, Physiology, and Cancer Biology Faculty Papers

Over a lifetime, hematopoietic stem and progenitor cells (HSPCs) are forced to repeatedly proliferate to maintain hematopoiesis, increasing their susceptibility to DNA damaging replication stress. However, the proteins that mitigate this stress, protect HSPC replication, and prevent aging-driven dysregulation are unknown. We report two evolutionarily conserved, ubiquitously expressed chromatin remodeling enzymes with similar DNA replication fork reversal biochemical functions, Zranb3 and Smarcal1, have surprisingly specialized roles in distinct HSPC populations. While both proteins actively mitigate replication stress and prevent DNA damage and breaks during lifelong hematopoiesis, the loss of either resulted in distinct biochemical and biological consequences. Notably, defective long-term …

Glucose-6-Phosphate Dehydrogenase Deficiency As A Cause For Nonimmune Hydrops Fetalis And Severe Fetal Anemia: A Systematic Review, Neel S. Iyer, Matthew H. Mossayebi, Tracy J. Gao, Lylach Haizler-Cohen, Daniele Di Mascio, Rodney A. Mclaren, Huda B. Al-Kouatly

Department of Obstetrics and Gynecology Faculty Papers

BACKGROUND: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is an X-linked recessive disorder that predisposes individuals to hemolysis due to an inborn error of metabolism. We performed a systematic literature review to evaluate G6PD deficiency as a possible etiology of nonimmune hydrops fetalis (NIHF) and severe fetal anemia.

METHODS: PubMed, OVID Medline, Scopus, and clinicaltrials.gov were queried from inception until 31 April 2023 for all published cases of NIHF and severe fetal anemia caused by G6PD deficiency. Keywords included "fetal edema," "hydrops fetalis," "glucose 6 phosphate dehydrogenase deficiency," and "fetal anemia." Cases with workup presuming G6PD deficiency as an etiology for NIHF and …

Motif-Vi Loop Acts As A Nucleotide Valve In The West Nile Virus Ns3 Helicase, Priti Roy, Zachary Walter, Lauren Berish, Holly Ramage, Martin Mccullagh

Department of Microbiology and Immunology Faculty Papers

The Orthoflavivirus NS3 helicase (NS3h) is crucial in virus replication, representing a potential drug target for pathogenesis. NS3h utilizes nucleotide triphosphate (ATP) for hydrolysis energy to translocate on single-stranded nucleic acids, which is an important step in the unwinding of double-stranded nucleic acids. Intermediate states along the ATP hydrolysis cycle and conformational changes between these states, represent important yet difficult-to-identify targets for potential inhibitors. Extensive molecular dynamics simulations of West Nile virus NS3h+ssRNA in the apo, ATP, ADP+Pi and ADP bound states were used to model the conformational ensembles along this cycle. Energetic and structural clustering analyses depict a clear …

Molecular Mechanism Of Bitter Taste Receptor Agonist-Mediated Relaxation Of Airway Smooth Muscle, Stanley Conaway, Weiliang Huang, Miguel A. Hernandez-Lara, Maureen A. Kane, Raymond B. Penn, Deepak A. Deshpande

Center for Translational Medicine Faculty Papers

G-protein-coupled receptors (GPCRs) belonging to the type 2 taste receptors (TAS2Rs) family are predominantly present in taste cells to allow the perception of bitter-tasting compounds. TAS2Rs have also been shown to be expressed in human airway smooth muscle (ASM), and TAS2R agonists relax ASM cells and bronchodilate airways despite elevating intracellular calcium. This calcium “paradox” (calcium mediates contraction by pro-contractile Gq-coupled GPCRs) and the mechanisms by which TAS2R agonists relax ASM remain poorly understood. To gain insight into pro-relaxant mechanisms effected by TAS2Rs, we employed an unbiased phosphoproteomic approach involving dual-mass spectrometry to determine differences in the phosphorylation of contractile-related …

Leukemia Cutis And Anterior Uveitis Associated With Chronic Myelomonocytic Leukemia, Kamran K. Harper, Vanessa Mutch, Jordan Philip Safran, Daisy Wu, Nidhi Aggarwal, Ekta Maheshwari, Allison K.

Chronic myelomonocytic leukemia (CMML) is an uncommon myeloid neoplasm with myeloproliferative and myelodysplastic features characterized by peripheral monocytosis and cytopenia. CMML may have cutaneous manifestations known as leukemia cutis (LC). LC in the setting of CMML may portend malignant transformation to acute myeloid leukemia (AML). The distribution and morphologic features of LC in CMML are highly variable and often nonspecific. CMML may coexist with numerous secondary autoimmune and inflammatory processes; this phenomenon presents a clinical challenge which can delay correct diagnosis and appropriate therapeutic management. Thus, careful consideration of extramedullary manifestations of CMML and associated autoimmune conditions in the skin …

Refining The Optimal Caf Cluster Marker For Predicting Tme-Dependent Survival Expectancy And Treatment Benefits In Nsclc Patients, Kai Li, Rui Wang, Guo-Wei Liu, Zi-Yang Peng, Ji-Chang Wang, Guo-Dong Xiao, Shou-Ching Tang, Ning Du, Jia Zhang, Jing Zhang, Hong Ren, Xin Sun, Yi-Ping Yang, Da-Peng Liu

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The tumor microenvironment (TME) plays a pivotal role in the onset, progression, and treatment response of cancer. Among the various components of the TME, cancer-associated fibroblasts (CAFs) are key regulators of both immune and non-immune cellular functions. Leveraging single-cell RNA sequencing (scRNA) data, we have uncovered previously hidden and promising roles within this specific CAF subgroup, paving the way for its clinical application. However, several critical questions persist, primarily stemming from the heterogeneous nature of CAFs and the use of different fibroblast markers in various sample analyses, causing confusion and hindrance in their clinical implementation. In this groundbreaking study, we …

SKMC Student Presentations and Publications

INTRODUCTION: During general anesthesia, frontal electroencephalogram (EEG) activity in the alpha frequency band (8-12 Hz) correlates with the adequacy of analgesia. Transcranial direct current stimulation (tDCS) and auditory stimulation, two noninvasive neuromodulation techniques, can entrain alpha activity in awake or sleeping patients. This study evaluates their effects on alpha oscillations in patients under general anesthesia.

METHODS: 30 patients receiving general anesthesia for surgery were enrolled in this two-by-two randomized clinical trial. Each participant received active or sham tDCS followed by auditory stimulation or silence according to assigned group (TDCS/AUD, TDCS/SIL, SHAM/AUD, SHAM/SIL). Frontal EEG was recorded before and after neuromodulation. …

Mutant Androgen Receptor Induces Neurite Loss And Senescence Independently Of Are Binding In A Neuronal Model Of Sbma, Jordyn Karliner, Y Liu, Diane Merry

Department of Biochemistry and Molecular Biology Faculty Papers

Spinal and bulbar muscular atrophy (SBMA) is a slowly progressing neuromuscular disease caused by a polyglutamine (polyQ)-encoding CAG trinucleotide repeat expansion in the androgen receptor (AR) gene, leading to AR aggregation, lower motor neuron death, and muscle atrophy. AR is a ligand-activated transcription factor that regulates neuronal architecture and promotes axon regeneration; however, whether AR transcriptional functions contribute to disease pathogenesis is not fully understood. Using a differentiated PC12 cell model of SBMA, we identified dysfunction of polyQ-expanded AR in its regulation of neurite growth and maintenance. Specifically, we found that in the presence of androgens, polyQ-expanded AR inhibited neurite …
