Using An Artificial Intelligence (Ai) Tool (Chatgpt) To Identify The Main Indications And Side Effects Of Drugs, Mai Elzieny, Christian Santiago, Zhenhong Qu

Posters

This study evaluated the efficacy of ChatGPT, an AI powered language model (1), in retrieving drug information for pathology practice compared to UpToDate. The research focused on 160 commonly prescribed drugs, assessing the speed and accuracy of information retrieval. Results showed that ChatGPT efficiently provided indications and side effects of multiple drugs in batches within seconds, comparable to UpToDate's information but remarkably faster (2). The study suggests that ChatGPT is a promising valuable tool to help pathologists in accessing drug information, potentially improving diagnostic accuracy and work efficiency

Optimize Artificial Intelligence Language Model Use In Medical Board Exams: Insights From Instruction Quality And Domain Context Analysis, Zhenhong Qu, Mai Elzieny, Kanika Arora

Posters

Artificial intelligence language models (AI-LMs) show promise in medical education and clinical problem solving, but their performance in medical board exams has been inconsistent (1,2,3).

This study investigated how prompt engineering and providing essential reference material influence AI-LM performance on board exam questions.

We tested ChatGPT and Claude-2 on 360 questions in various formats under three conditions: simple prompt, elaborate CRAFTS prompt, and CRAFTS prompt with references (CRAFTS stands for context, role, action, format, tone, and style).

Results showed significant improvement in accuracy from simple prompts (67-83.5%) to CRAFTS prompts (76.2-92.5%) to CRAFTS prompts with references (97.3- 99.4%)

Utility Of Cystatin C-Based Equation For The Estimation Of Glomerular Filtration Rate In A Pediatric Population, Ridwan B Ibrahim, Poyyapakkam Srivaths, Estella Tam, Sridevi Devaraj

Faculty, Staff and Students Publications

Background: The accurate assessment of kidney function is vital for the early detection of kidney damage. The estimated glomerular filtration rate GFR (eGFR) from serum cystatin C (CysC) and creatinine-based equations are commonly used in clinical practice as an alternative to the invasive measured glomerular filtration rate (mGFR), which is the usually accepted overall best index of kidney function in health and disease. Recently the CKiD under 25 (CkiD U25) equations have been shown to perform well in children and young adults with chronic kidney disease (CKD). In this focused report, we evaluated the performance of the CkiD U25 equations …

Neurology Faculty Publications

TDP-43 proteinopathy is a salient neuropathologic feature in a subset of frontotemporal lobar degeneration (FTLD-TDP), in amyotrophic lateral sclerosis (ALS-TDP), and in limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC), and is associated with hippocampal sclerosis of aging (HS-A). We examined TDP-43-related pathology data in the National Alzheimer’s Coordinating Center (NACC) in two parts: (I) availability of assessments, and (II) associations with clinical diagnoses and other neuropathologies in those with all TDP-43 measures available. Part I: Of 4326 participants with neuropathology data collected using forms that included TDP-43 assessments, data availability was highest for HS-A (97%) and ALS (94%), followed by …

Thyroid Cartilage Metastases From Prostate Cancer On 18f Psma Pet Ct: A Case Series, Poonamjeet Loyal, Samuel Gitau, Khalid Makhdomi

Imaging & Diagnostic Radiology, East Africa

Prostate cancer metastases to the thyroid cartilage is an extremely rare phenomenon. We report three cases of advanced prostate carcinoma with metastases to the thyroid cartilage identified on 18F prostate-specific membrane antigen-1007 (PSMA-1007) positron emission tomography (PET)/computed tomography (CT). The pathophysiology and possibility for under-reporting are also discussed. Prostate cancer metastases to the larynx should be considered in the differential diagnosis of thyroid cartilage lesions in patients with advanced prostate cancer and is associated with poor prognosis.

Erdheim-Chester Disease Presenting In The Foramen Magnum With Mass Effect Of A 39-Year-Old Male, Joseph Fullmer, Brandon Metcalf, Casey Schukow

Conference Presentation Abstracts

Background: Erdheim-Chester disease (ECD) is a rare clonal histiocytosis neoplastic condition. This condition is characterized by a non-specific infiltration of foamy macrophages in multiple organs, such as the bone or skeletal system (>95%), retroperitoneum, kidneys, and heart, resulting in inappropriate inflammation, fibrosis, and multi-end organ dysfunction. central nervous system (CNS) is present in a minority of cases. This condition is extremely rare with only a few hundred cases reported in medical literature. Methods: We present a case of ECD in a 39-year-old male with past medical history for type-2 diabetes mellitus, neuropathy, and low testosterone on replacement therapy who …

A Wide Range Of Fusions And Alterations Are Detected In Myb- Or Mybl1- Altered Gliomas, S Rajan, Z Abdullaev, H Lidov, Y Wilson, D Thomas, Joseph Fullmer, K Jones, D Brown, P Kobalka, A Buckley

Conference Presentation Abstracts

Background: Diffuse astrocytoma, MYB- or MYBL1-altered are rare pediatric low-grade gliomas, reported in young adults that are often associated with refractory seizures and generally located in the supratentorial compartment. While GFAP is consistently expressed, interestingly OLIG2 expression (another glial marker) is not a common finding. Here we describe the various associated genetic alterations. Methods: Fourteen cases matching to methylation class (MC), Diffuse astrocytoma, MYB- or MYBL1-altered, were analyzed for structural variants/fusion partners. Results: The median age was 16 years (range 1-64), with male: female ratio of 1:1. All but one was supratentorial (one located in pons). On histology, some showed …

Displacement Of Hospital-Acquired, Methicillin-Resistant Staphylococcus Aureus Clones By Heterogeneous Community Strains In Kenya Over A 13-Year Period, Justin Nyasinga, Zubair Munshi, Collins Kigen, Andrew Nyerere, Lillian Musila, Andrew Whitelaw, Wilma Ziebuhr, Gunturu Revathi

Pathology, East Africa

We determined antibiotic susceptibility and employed Oxford Nanopore whole-genome sequencing to explore strain diversity, resistance, and virulence gene carriage among methicillin-resistant Staphylococcus aureus (MRSA) strains from different infection sites and timepoints in a tertiary Kenyan hospital. Ninety-six nonduplicate clinical isolates recovered between 2010 and 2023, identified and tested for antibiotic susceptibility on the VITEK ID/AST platform, were sequenced. Molecular typing, antibiotic resistance, and virulence determinant screening were performed using the relevant bioinformatics tools. The strains, alongside those from previous studies, were stratified into two periods covering 2010–2017 and 2018–2023 and comparisons were made. Mirroring phenotypic profiles, aac(6′)-aph(2″) [aminoglycosides]; gyrA (S84L) …

Individual Disruption Of 12 Testis-Enriched Genes Via The Crispr/Cas9 System Does Not Affect The Fertility Of Male Mice, Akira Suzuki, Norikazu Yabuta, Keisuke Shimada, Daisuke Mashiko, Keizo Tokuhiro, Yuki Oyama, Haruhiko Miyata, Thomas X Garcia, Martin M Matzuk, Masahito Ikawa

Faculty, Staff and Students Publications

More than 1200 genes have been shown in the database to be expressed predominantly in the mouse testes. Advances in genome editing technologies such as the CRISPR/Cas9 system have made it possible to create genetically engineered mice more rapidly and efficiently than with conventional methods, which can be utilized to screen genes essential for male fertility by knocking out testis-enriched genes. Finding such genes related to male fertility would not only help us understand the etiology of human infertility but also lead to the development of male contraceptives. In this study, we generated knockout mice for 12 genes (Acrv1, Adgrf3, …

Men or mice with homozygous serine/threonine kinase 33 (STK33) mutations are sterile owing to defective sperm morphology and motility. To chemically evaluate STK33 for male contraception with STK33-specific inhibitors, we screened our multibillion-compound collection of DNA-encoded chemical libraries, uncovered potent STK33-specific inhibitors, determined the STK33 kinase domain structure bound with a truncated hit CDD-2211, and generated an optimized hit CDD-2807 that demonstrates nanomolar cellular potency (half-maximal inhibitory concentration = 9.2 nanomolar) and favorable metabolic stability. In mice, CDD-2807 exhibited no toxicity, efficiently crossed the blood-testis barrier, did not accumulate in brain, and induced a reversible contraceptive effect that …
