Objective: To solve major clinical natural language processing (NLP) tasks using a unified text-to-text learning architecture based on a generative large language model (LLM) via prompt tuning.

Methods: We formulated 7 key clinical NLP tasks as text-to-text learning and solved them using one unified generative clinical LLM, GatorTronGPT, developed using GPT-3 architecture and trained with up to 20 billion parameters. We adopted soft prompts (ie, trainable vectors) with frozen LLM, where the LLM parameters were not updated (ie, frozen) and only the vectors of soft prompts were updated, known as prompt tuning. We added additional soft prompts as a prefix …

Strategies For The Development Of Metalloimmunotherapies, Xiaoqi Sun, Xingwu Zhou, Xiaoyue Shi, Omar A Abed, Xinran An, Yu Leo Lei, James J Moon

Faculty, Staff and Student Publications

Metal ions play crucial roles in the regulation of immune pathways. In fact, metallodrugs have a long record of accomplishment as effective treatments for a wide range of diseases. Here we argue that the modulation of interactions of metal ions with molecules and cells involved in the immune system forms the basis of a new class of immunotherapies. By examining how metal ions modulate the innate and adaptive immune systems, as well as host-microbiota interactions, we discuss strategies for the development of such metalloimmunotherapies for the treatment of cancer and other immune-related diseases.

Determinant Of 30-Day Mortality Of Pulmonary Legionellosis: Do Coinfections Matter?, Takahiro Matsuo, Sebastian Wurster, Ying Jiang, Jeffrey Tarrand, Scott E Evans, Dimitrios P Kontoyiannis

Faculty, Staff and Student Publications

We retrospectively reviewed 64 cases of cancer with pulmonary legionellosis (Legionella pneumophila in 73%). Nearly all patients received Legionella-active antibiotics, yet 30-day mortality was 23%. Independent predictors of 30-day mortality were hyponatremia, bilateral lung involvement, and Sequential Organ Failure Assessment score ≥5. Lung coinfections were common (31%) but did not significantly increase mortality.

Objectives: Precise literature recommendation and summarization are crucial for biomedical professionals. While the latest iteration of generative pretrained transformer (GPT) incorporates 2 distinct modes-real-time search and pretrained model utilization-it encounters challenges in dealing with these tasks. Specifically, the real-time search can pinpoint some relevant articles but occasionally provides fabricated papers, whereas the pretrained model excels in generating well-structured summaries but struggles to cite specific sources. In response, this study introduces RefAI, an innovative retrieval-augmented generative tool designed to synergize the strengths of large language models (LLMs) while overcoming their limitations.

Materials and methods: RefAI utilized PubMed for systematic literature retrieval, …

The Association Of Glycated Hemoglobin And Lipid Profile With Peripheral Artery Disease In Metabolic Syndrome Patients From Northwestern Algeria, Imane Bouragba, Mustapha Diaf, Sarra Souiah, Asmaa Melih, Attouya Mellali

Baghdad Science Journal

Glycated hemoglobin (HbA1c) was incorporated as an indicator of dysglycemia, as opposed to fasting glycaemia, for the purpose of classifying patients based on their vascular incidents. This choice was made due to HbA1c's robust correlation with vascular factors like pulse wave velocity, intima media thickness, and the albumin/creatinine ratio (ACR). However, the relationship between HbA1c and lipid profile in developing artery disease remain uncertain. We set out to investigate the association of HbA1c and lipid profile with peripheral artery diseases (PAD) in patients with metabolic syndrome (MetS) in north-western Algeria. Our cross sectional study was carried out during six months. …

Enterotoxigenic Escherichia coli (ETEC) cause hundreds of millions of cases of infectious diarrhea annually, predominantly in children from low-middle income regions. Notably, in children, as well as volunteers challenged with ETEC, diarrheal severity is significantly increased in blood group A (bgA) individuals. EtpA, is a secreted glycoprotein adhesin that functions as a blood group A lectin to promote critical interactions between ETEC and blood group A glycans on intestinal epithelia for effective bacterial adhesion and toxin delivery. EtpA is highly immunogenic resulting in robust antibody responses following natural infection and experimental challenge of volunteers with ETEC. To understand how EtpA …

BACKGROUND: An estimated one fourth of the world's population is infected with Mycobacterium tuberculosis, and 5-10% of those infected develop tuberculosis in their lifetime. Preventing tuberculosis is one of the most underutilized but essential components of curtailing the tuberculosis epidemic. Moreover, current evidence illustrates that tuberculosis manifestations occur along a dynamic spectrum from infection to disease rather than a binary state as historically conceptualized. Elucidating determinants of transition between these states is crucial to decreasing the tuberculosis burden and reaching the END-TB Strategy goals as defined by the WHO. Vaccination, detection of infection, and provision of preventive treatment are key …

BACKGROUND: Dupilumab is a monoclonal antibody that targets the interleukin (IL)-4 receptor alpha subunit, thus blocking the effects of IL-4 and IL-13, and has shown efficacy in treating various conditions including asthma, atopic dermatitis, eosinophilic esophagitis, and others. Because of its immune modulatory effects, clinical trials that studied dupilumab did not allow patients to receive live vaccines during the clinical trials because of an abundance of caution, and thus package inserts recommend that patients who are being treated with dupilumab should avoid live vaccines. Because dupilumab is now approved for use in patients from 6 months of age for the …

BACKGROUND: Several antiretroviral therapy (ART) medications have been associated with increased cardiovascular risk, but less is known about the safety of modern ART. We sought to compare the risk of major adverse cardiac events (MACEs) among different ART regimens.

METHODS: Using insurance claims databases from 2008 to 2020, we identified adults aged <65 years who newly initiated ART. We compared non-nucleoside reverse transcriptase inhibitor (NNRTI)-based regimens to protease inhibitors (PI)- and integrase inhibitors (INSTI)-based regimens. We used propensity score-weighted Kaplan-Meier functions to estimate the 6, 12, 18, 24, 36, and 48 months' risk and risk differences (RD) of MACE.

RESULTS: Among 37 935 ART initiators (median age, 40 years; 23% female; 26% Medicaid-insured), 45% started INSTI-, 16% PI-, and 39% NNRTI-based regimens. MACE occurred in 418 individuals (1.1%) within 48 months after ART initiation. Compared to NNRTI initiators, the risk of MACE was higher at 12 months …

Epidemiological research over the past two decades has highlighted substance use disparities that affect Native Hawaiian and Pacific Islander youth, and the lack of effective approaches to address such disparities (Okamoto et al., 2019). The Ho'ouna Pono curriculum is a culturally grounded, teacher-implemented, video-enhanced substance use prevention program that has demonstrated efficacy in rural Hawai'i in a large-scale trial (Okamoto et al., 2019). Despite its potential to ameliorate health disparities and address youth substance use, prevention programs such as Ho'ouna Pono have been poorly disseminated and implemented across Hawai'i, raising the question:

Data Driven Decision Making For Sustainable Planning And Operations Of Large Scale Networks, Bahareh Kargar

Dissertations

This dissertation explores data-driven decision-making networks, focusing on sustainable planning and operations for large-scale systems such as healthcare supply chains and power systems. One significant application in healthcare is the optimization of vaccine supply chains. An agent-based simulation-optimization modeling framework is developed to enhance the efficiency and sustainability of vaccine distribution. First, an agent-based epidemiological model of COVID-19 is extended to capture disease transmission dynamics and forecast the number of susceptible individuals and infections. Then, a sustainable vaccine supply chain considering the impacts of greenhouse gases is developed and integrated with the simulation model to minimize total costs and environmental …
