Recent Advances In The Identification And Quantification Of Xylazine And Medetomidine In Biological Specimens, Bridgit O Crews

2020-Current year OA Pubs

Xylazine is a veterinary sedative that is frequently detected in the illicit drug supply, often found mixed with illicitly manufactured fentanyl (IMF). It has been detected in the blood of overdose victims and patients who use illicit drugs. Xylazine is not approved for use in humans. It is an alpha-2-adrenergic receptor agonist that causes deep sedation that is non-responsive to naloxone, the antidote for opioid overdose. Chronic exposure to xylazine has been linked to severe wounds that can progress to amputation. Medetomidine is another related veterinary sedative that has more recently emerged as an adulterant in IMF. Medetomidine is also …

Chimeric Antigen Receptor Natural Killer (Car-Nk) Cells: From Preclinical Promise To Clinical Reality In Cancer Immunotherapy, Hunter Cassidy Cochran, Kevin Ashkan Ghobadi, Armin Ghobadi

2020-Current year OA Pubs

Chimeric antigen receptor (CAR) natural killer (NK) cell therapy represents an emerging frontier in cancer immunotherapy. CAR-NK cells offer the potential for "off-the-shelf" treatments with a favorable safety profile, due in part to their innate capacity for HLA-unrestricted tumor targeting and an absence of graft-versus-host disease. Landmark clinical studies using cord blood - derived CAR-NK cells and another employing iPSC-derived CAR-NK cells have reported impressive response rates, durable remissions, and minimal toxicity. Furthermore, a growing landscape of ongoing clinical trials is exploring innovative strategies to enhance persistence, overcome solid tumor challenges, and prevent antigen escape.

Whose Burden, Whose Benefit? Revisiting Ethical Trade-Offs In The Who Guidelines On Scaling Up Mass Azithromycin Administration, Maple Goh, A. M. Viens, Safura Abdool Karim, Aaron S. Kesselheim, Kevin Outterson

Faculty Scholarship

Author summary

• New evidence suggests that mass drug administration of azithromycin (MDAA) can significantly reduce childhood mortality in high-burden, low-resource settings, yet the World Health Organization’s (WHO) 2020 guidelines take a cautious approach due to concerns about antimicrobial resistance (AMR).
• While the WHO guidelines cite ethical principles, they insufficiently address key considerations, such as intergenerational justice, equitable burden sharing, and the structural determinants of health that shape infectious disease vulnerability.
• Global AMR policy often prioritizes conservation over access in ways that disproportionately burden low-income countries, despite high-income countries also bearing significant responsibility for the emergence and spread of AMR.

Decorin Evokes A Pro-Lysosomal Pathway In Lymphatic Endothelial Cells, Gabriel J. Pascal, Dipon K. Mondal, Sadie Kim, Christopher Xie, Devanarayanan Siva Sankar, Jörn Dengjel, Renato V. Iozzo

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

The lymphatic system is critical to the body's immune and circulatory system, and lymphangiogenesis, the development of new lymphatic vessels from pre-existing ones, is a significant process capitalized upon by cancer during tumorigenesis. Decorin is a small leucine-rich proteoglycan which we have previously shown to be anti-tumorigenic and a suppressor of lymphangiogenesis. We have also shown that decorin exercises its anticancer properties through its ability to evoke autophagy. Through a comprehensive and unbiased proteomic analysis, we explored the implications of decorin exposure on protein expression within mouse lymphatic endothelial cells. We discovered that decorin enriches several protein pathways, notably proteasomal …

Kimmel Cancer Center Faculty Papers

Human T-cell leukemia virus type 1 (HTLV-1), the first oncogenic human retrovirus, causes adult T-cell leukemia/lymphoma (ATLL), an aggressive neoplasm of mature CD4+ T-cells that is incurable in most patients and is associated with a median survival of less than 1 year. HTLV-1 also causes inflammatory disorders, including HTLV-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and uveitis. The estimated lifetime risks of ATLL and HAM/TSP in HTLV-1 carriers are 3-5% and 0.25-1.8%, respectively. Although there is uncertainty about other health effects of HTLV-1, a recent meta-analysis showed an association between HTLV-1 and cardiovascular, cerebrovascular, and metabolic diseases and a 57% increased risk …

Improving Data-Driven Gated (Ddg) Pet And Ct Registration In Thoracic Lesions: A Comparison Of Ai Registration And Ddg Ct, Tinsu Pan, M Allan Thomas, Yang Lu, Dershan Luo

Faculty, Staff and Student Publications

Purpose: Misregistration between CT and PET can result in mis-localization and inaccurate quantification of the tracer uptake in PET. Data-driven gated (DDG) CT can correct registration and quantification but requires a radiation dose of 1.3 mSv and 1 min of acquisition time. AI registration (AIR) does not require an additional CT and has been validated to improve registration and reduce the 'banana' misregistration artifacts around the diaphragm. We aimed to compare a validated AIR and DDG CT in registration and quantification of avid thoracic lesions misregistered in DDG PET scans.

Methods: Thirty PET/CT patient data (23 with 18F-FDG, 4 with …
