The gut microbiota has emerged as a critical determinant of immune checkpoint inhibitor (ICI) efficacy, resistance, and toxicity. Retrospective and prospective studies profiling the taxonomic composition of intestinal microbes of patients treated with ICI have revealed specific gut microbial signatures associated with response. By contrast, dysbiosis, which can be caused by chronic inflammatory processes (such as cancer) or comedications, is a risk factor of resistance to ICI. Recent large-scale meta-analyses have confirmed that antibiotic (ATB) use before or during ICI therapy alters the microbiota repertoire and significantly shortens overall survival, even after adjusting for prognostic factors. These results underscore the …

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano Jun 2025

Biomolecular Condensates In Immune Cell Fate, Srikanth Kodali, Caroline M Sands, Lei Guo, Yun Huang, Bruno Di Stefano

Faculty, Staff and Students Publications

Fate decisions during immune cell development require temporally precise changes in gene expression. Evidence suggests that the dynamic modulation of these changes is associated with the formation of diverse, membrane-less nucleoprotein assemblies that are termed biomolecular condensates. These condensates are thought to orchestrate fate-determining transcriptional and post-transcriptional processes by locally and transiently concentrating DNA or RNA molecules alongside their regulatory proteins. Findings have established a link between condensate formation and the gene regulatory networks that ensure the proper development of immune cells. Conversely, condensate dysregulation has been linked to impaired immune cell fates, including ageing and malignant transformation. This Review …

Background: Diagnosis of Kingella kingae skeletal system infections is made challenging by the microbe's fastidious nature. Detection and quantification of circulating microbial cell-free DNA (mcfDNA) in plasma by the Karius Test, a commercial metagenomic sequencing test, may offer promise in diagnosing pediatric spinal infections caused by difficult-to-culture organisms such as K. kingae .

Methods: Plasma mcfDNA sequencing detections of K. kingae from April 2018 to December 2020 were reviewed to identify pediatric (age < 18 years) patients. Medical charts of those with spinal infections were reviewed, and mcfDNA sequencing diagnostic performance was compared with usual care tests (ie, cultures, polymerase chain reaction).

Results: Ten children with K. kingae spinal infections were identified across 7 institutions. The median age was 16.5 months (range 11-23 months). All case-patients had vertebral osteomyelitis …

The Impact Of Nicu Death On Bereaved Mothers, Jennie Terranova Jun 2025

The Impact Of Nicu Death On Bereaved Mothers, Jennie Terranova

University Honors Theses

Infant loss in the United States occurs 5.6 per 1,000 live births. This paper examines risk factors that contribute to neonatal death. Prematurity is a risk factor for NICU admission. A portion of premature babies receiving care in the NICU will die. The stressful nature of the NICU has been studied widely in journals. The impact of NICU death on hospital staff and bereaved parents has been studied less. Mortality studies suggest that bereaved mothers are at a high risk of dying within the first 5 years after their child has died. Despite the frequency of maternal death post-child loss, …

Background: Black and Hispanic women in the United States continue to bear disproportionate incidence of HIV related to sexual transmission and injection drug use. Specifically, women with substance use disorders (SUDs) are more likely to engage in vaginal or anal condomless sex associated with HIV transmission. Pre-exposure prophylaxis (PrEP) is a highly effective HIV prevention tool but is not widely used by racial or ethnic minority women. Effective interventions for engaging women with SUDs in HIV prevention interventions that are culturally appropriate and, therefore, more appealing to racial or ethnic minority women with SUDs are critically needed.

Objective: This 3-phased …

Tacrolimus is the most commonly used immunosuppression drug after solid organ transplantation; however, its dosing is challenging due to substantial inter-individual variability, often resulting in blood levels that deviate from the target therapeutic range. We explored whether a dynamically customized, phenotypic-outcome-guided drug dosing method could improve maintenance of drug trough levels within pre-determined target ranges, focusing on tacrolimus immediately after liver transplantation. This single-center, partially blinded, completed clinical trial involved 62 adults undergoing liver transplantation, block randomized into parallel groups: standard-of-care (SOC) clinician-determined or Phenotypic Personalized Medicine (PPM)-guided tacrolimus dosing. The primary outcome was percentage of post-transplant days with large …

Health Equity and Quality Improvement (HEQI) Summit

Background

Pre-Exposure Prophylaxis (PrEP) significantly reduces the risk of contracting HIV:

  • Reduces risk from sexual contact by 99%
  • Reduces risk from injection drug use by at least 74%

Despite its effectiveness, PrEP is underutilized in the USA.

  • In 2019, an estimated 224,000 Americans received a prescription for PrEP despite 1.1 million people having indications for PrEP.
  • Lack of provider knowledge surrounding PrEP clinical guidelines is a common reason for underutilization.
