Targeting Ptp4a3 And Kvx-053 Mitigates Alcohol-Amplified Sars-Cov-2 Spike Protein-Induced Acute Lung Injury, Pavel A. Solopov, Ruben Manuel Luciano Colunga Biancatelli, Elizabeth R. Sharlow, John S. Lazo, John D. Catavas

Bioelectrics Publications

Introduction: Chronic alcohol exposure is associated with increased vulnerability to acute respiratory distress syndrome (ARDS), and emerging evidence suggests that this susceptibility extends to the severe respiratory manifestations of COVID- 19. The SARS-CoV-2 Spike Protein S1 subunit (S1SP) can independently trigger robust inflammatory and vascular injury responses in the lung, and our prior work demonstrated that chronic alcohol consumption markedly intensifies these effects in mice. PTP4A3 phosphatase is a key regulator of inflammation and endothelial barrier function. In this study, we investigated whether the PTP4A3 inhibitor KVX-053 can counteract alcohol-enhanced S1SP-induced lung injury in K18-hACE2 mice.

Methods: Animals were maintained …

Diagnosing The Discourse: How The Academy Of Breastfeeding Medicine Constructs And Constrains Treatment Of Tethered Oral Tissues, Mary E. Miller

Antioch University Dissertations & Theses

While breastfeeding is recognized as fundamental to global public health, oral restrictions that can affect infant latch, milk transfer, and feeding efficiency warrant further examination within policy frameworks. This dissertation proposes an expanded conceptualization of tethered oral tissues (TOTs) that encompasses not only anatomical frenal restrictions but also fascial tensions, neuromuscular limitations, and other conditions restricting orofacial function that may be congenital or acquired. The purpose of this study was to critically examine how this clinical guidance document shapes understandings and responses to TOTs. Using Carol Bacchi’s “What’s the Problem Represented to Be?” approach, a critical discourse analysis of the …

Implemented by the Public Health Accreditation Board (PHAB), the program aims to improve and protect population health by advancing the quality and performance of public health departments. Given that accreditation is a key strategy for strengthening public health systems, it is critical to build robust …

Hepatitis C Among Persons Who Inject Drugs In New York State: Progress Towards Elimination, Meredith A. Barranco

Electronic Theses & Dissertations (2024 - present)

Background: Hepatitis C virus (HCV) infection is one of the leading causes of liver disease in the United States (US) and worldwide. In the United States today, HCV is transmitted primarily through injection drug use (IDU) and therefore disproportionately impacts persons who inject drugs (PWID), a population with a range of complex social and health needs. HCV is not vaccine-preventable but can be cured in over 90% of cases with an 8–12-week course of daily direct-acting antiviral (DAA) medication. Since approval of curative medications in 2014, various jurisdictions have developed plans to eliminate HCV. In 2021, the New York State …

Latent Classification Of Time-Dependent Transition Rates In Longitudinal Binary Outcome Data

Faculty, Staff and Student Publications

Continuous-time Markov chain (CTMC) models and latent classification methods are commonly used to analyze longitudinal categorical outcomes in medical research. While CTMC models are popular for their simplicity and effectiveness, their assumption of constant transition rates presents limitations in capturing dynamic behaviors. To address this, non-homogeneous continuous-time Markov chains (NH-CTMCs) have been developed, incorporating time-varying transition rates to enhance model flexibility. In this study, we leverage closed-form transition probabilities for a fully ergodic two-state NH-CTMC model and propose a latent class clustering approach to identify heterogeneous transition rate patterns within the population. We emphasize the potential advantages of these models …

A Qualitative Examination Of Human Papillomavirus Vaccine Access, Beliefs, And Behaviors Among Adult Males Aged 18–35: Applying The Health Stigma And Discrimination Framework, Serena A Rodríguez

Faculty, Staff and Student Publications

Background: Males, who disproportionately account for 83% of oropharyngeal cancer cases, are underrepresented in health promotion research, including human papillomavirus (HPV) vaccination studies. The initial exclusion of males in HPV vaccine research, policies, and interventions has negatively affected male vaccine uptake. Furthermore, stigma, a well-documented barrier to healthcare engagement, has been overlooked in HPV vaccination behaviors. This study aimed to provide a more contextualized understanding of HPV vaccine disparities among adult males by applying the Health Stigma and Discrimination Framework (HSDF) to examine how stigma is produced, enacted, and sustained across social systems, which may impact male vaccine uptake.

Improving Overall Risk Ranking Via Subgroup-Level Information Borrowing In Survival Risk Stratification

Faculty, Staff and Student Publications

Effective risk stratification is essential for providing tailored therapies, improving patient outcomes, and optimizing healthcare resources by identifying sub-populations with similar health risks. However, accurate risk ranking is challenging in the presence of heterogeneous subgroups. Under these instances, subgroup-level information can be leveraged to refine the overall risk ranking. We propose a novel approach that integrates within-subgroup risk ranking percentiles to enhance the overall cohort risk stratification. This method uses both a global model and subgroup-specific models along with optimized weights to improve discriminatory performance across the entire cohort. The proposed method is validated through extensive simulations and applied to …
