Chronoradiobiology Of Breast Cancer: The Time Is Now To Link Circadian Rhythm And Radiation Biology, Nicolas Nelson, Joseph Lombardo, Lauren Matlack, Alexandria Smith, Kamryn Hines, Wenyin Shi, Nicole L Simone

Department of Radiation Oncology Faculty Papers

Circadian disruption has been linked to cancer development, progression, and radiation response. Clinical evidence to date shows that circadian genetic variation and time of treatment affect radiation response and toxicity for women with breast cancer. At the molecular level, there is interplay between circadian clock regulators such as PER1, which mediates ATM and p53-mediated cell cycle gating and apoptosis. These molecular alterations may govern aggressive cancer phenotypes, outcomes, and radiation response. Exploiting the various circadian clock mechanisms may enhance the therapeutic index of radiation by decreasing toxicity, increasing disease control, and improving outcomes. We will review the body’s natural circadian …


Immigration, Politics, And Mental Health: An Undergraduate Independent Study, Abigail O. Akande, Erinn K. Rajapaksa Feb 2022

Immigration, Politics, And Mental Health: An Undergraduate Independent Study, Abigail O. Akande, Erinn K. Rajapaksa

Journal of Human Services: Training, Research, and Practice

The implications of a polarizing political climate on the plight of immigrants with disabilities in the United States are physiological and emotional. Rehabilitation and human services professionals are inclined to recognize the intersection of the process of immigration with related legislation and the presence of disability. Undergraduate students of relevant disciplines can benefit from the focused investigation that an independent study can provide – particularly because legislative directives evolve so rapidly, are directly associated with service provision and the availability of resources, and draw upon training and continuing education expectations from a variety of practitioner ethical codes.


Educated There, But Employed Here: The Unique Experiences Of Internationally Educated Nurses, Nnenna Onuoha Feb 2022

Educated There, But Employed Here: The Unique Experiences Of Internationally Educated Nurses, Nnenna Onuoha

Dissertations, Theses, and Capstone Projects

The educational background of nurses impacts their delivery of evidence-based, safe, quality, and patient-centered care. Obtaining a master’s degree can lead to patient benefits such as decreased lengths of hospital stay, reduced mortalities, reduced hospitalization costs, reduction in total patient falls, and nurse benefits such as increased job satisfaction and critical thinking skills. Internationally educated nurses (IENs) make up five percent of the 3.9 million nursing workforce, according to the National Sample Survey of Registered Nurses (NSSRN) data collected by the Bureau of Health Workforce. IENs obtain fewer master’s degrees than U.S-educated nurses, as the NSSRN data shows that 40% …

Tuberculosis (TB) in humans is characterized by formation of immune-rich granulomas in infected tissues, the architecture and composition of which are thought to affect disease outcome. However, our understanding of the spatial relationships that control human granulomas is limited. Here, we used multiplexed ion beam imaging by time of flight (MIBI-TOF) to image 37 proteins in tissues from patients with active TB. We constructed a comprehensive atlas that maps 19 cell subsets across 8 spatial microenvironments. This atlas shows an IFN-γ-depleted microenvironment enriched for TGF-β, regulatory T cells and IDO1

Faculty, Staff and Student Publications

In this study we aimed to develop nomogram models for predicting the overall survival (OS) and cancer-specific survival (CSS) of patients with metaplastic breast cancer (MBC). Data of patients diagnosed with MBC from 1973 to 2015 were collected from the Surveillance, Epidemiology, and End Results (SEER) database. Univariate and multivariate Cox analyses were performed to identify independent prognostic factors for OS and CSS of MBC patients. The obtained prognostic variables were combined to construct nomogram models for predicting OS and CSS in patients with MBC. Model performance was evaluated using concordance index (C-index) and calibration plots. Data from 1125 patients …

Evaluation Of Programmed Death Ligand 1 Expression In Cytology To Determine Eligibility For Immune Checkpoint Inhibitor Therapy In Patients With Head And Neck Squamous Cell Carcinoma, Zhonghua Liu, Michelle Williams, John Stewart, Bonnie S Glisson, Clifton Fuller, Sinchita Roy-Chowdhuri

Faculty, Staff and Student Publications

Background: Immune checkpoint inhibitors targeting the programmed cell death protein 1 (PD-1)/programmed cell death ligand 1 (PD-L1) pathway have recently emerged as a frontline treatment for head and neck squamous cell carcinoma (HNSCC). The evaluation of PD-L1 expression by immunohistochemistry in histologic samples is used to determine the eligibility of patients with HNSCC for immunotherapy. Patients with newly diagnosed HNSCC are frequently diagnosed by fine-needle aspiration (FNA) of lymph nodes with metastatic disease. However, the evaluation of PD-L1 expression with the proposed combined positive score (CPS) has not been well established in cytology specimens.

Methods: This study retrospectively identified 21 …

Improving Transcatheter Aortic Valve Interventional Predictability Via Fluid-Structure Interaction Modelling Using Patient-Specific Anatomy, Vijay Govindarajan, Arun Kolanjiyil, Nils P Johnson, Hyunggun Kim, Krishnan B Chandran, David D Mcpherson

Faculty, Staff and Student Publications

Transcatheter aortic valve replacement (TAVR) is now a standard treatment for high-surgical-risk patients with severe aortic valve stenosis. TAVR is being explored for broader indications including degenerated bioprosthetic valves, bicuspid valves and for aortic valve (AV) insufficiency. It is, however, challenging to predict whether the chosen valve size, design or its orientation would produce the most-optimal haemodynamics in the patient. Here, we present a novel patient-specific evaluation framework to realistically predict the patient's AV performance with a high-fidelity fluid-structure interaction analysis that included the patient's left ventricle and ascending aorta (AAo). We retrospectively evaluated the pre- and post-TAVR dynamics of …

Purpose:

Radiation epidemiology studies of childhood cancer survivors treated in the pre-computed tomography (CT) era reconstruct the patients’ treatment fields on computational phantoms. For such studies, the phantoms are commonly scaled to age at the time of radiotherapy treatment because age is the generally available anthropometric parameter. Several reference size phantoms are used in such studies, but reference size phantoms are only available at discrete ages (e.g.: newborn, 1, 5, 10, 15, and Adult). When such phantoms are used for RT dose reconstructions, the nearest discrete-aged phantom is selected to represent a survivor of a specific age. In this work, …

Faculty, Staff and Student Publications

While aerobic glycolysis, or the Warburg effect, has for a long time been considered a hallmark of tumor metabolism, recent studies have revealed a far more complex picture. Tumor cells exhibit widespread metabolic heterogeneity, not only in their presentation of the Warburg effect but also in the nutrients and the metabolic pathways they are dependent on. Moreover, tumor cells can switch between different metabolic phenotypes in response to environmental cues and therapeutic interventions. A framework to analyze the observed metabolic heterogeneity and plasticity is, however, lacking. Using a mechanistic model that includes the key metabolic pathways active in tumor cells, …

Weighting Admission Scores To Balance Predictiveness-Diversity: The Pareto-Optimization Approach, Filip Lievens, Paul R. Sackett, Wilfried De Corte

Research Collection Lee Kong Chian School Of Business

Context: Although many medical schools seek to improve diversity, they grapple with the challenge of how to weight the scores of different admission methods to achieve a balance between obtaining high predictiveness and ensuring diversity in the selected student pool. Yet, in large-scale employment settings, substantial progress has been made on this front: Pareto-optimization has been introduced as an elegant statistical tool to assist decision makers in determining the weights assigned to selection methods in advance (before the selection has taken place) so that a selection system is designed to achieve an optimal balance as reflected by the trade-off that …

Lonny Shavelson v. California Department of Health Care Services

From the Argument

Whether and to what extent doctors should be allowed to participate in intentionally ending the lives of their patients is one of the most important questions in public bioethics. The vast majority of states allow no physician participation at all. California is one of nine states that have passed laws allowing physicians to “assist” a patient’s suicide by making lethal drugs available. But each stops there. No state allows what the plaintiffs in this case now demand: that doctors be allowed to actively euthanize patients by …

Short-Term Impact Of Covid-19 On Consumption Spending And Its Underlying Mechanisms: Evidence From Singapore, Seonghoon Kim, Kanghyock Koh, Xuan Zhang

Research Collection School Of Economics

We examine the short-term impact of COVID-19 on consumption spending and labor market outcomes. Using monthly panel data of individuals mainly aged 50–70 in Singapore, we find that COVID-19 reduced consumption spending and labor market outcomes immediately after its outbreak, and its negative impact quickly evolved. At its peak, the pandemic reduced total household consumption spending by 22.8% and labor income by 5.9% in April. Probability of full-time work also went down by 1.2 pp and 6.0 pp in April and May, respectively, but employment and self-employment were only mildly affected. Our heterogeneity analysis indicates that the reduction in consumption …


Heterogeneous Health Effects Of Medical Marijuana Legalization: Evidence From Young Adults In The United States, Junxing Chay, Seonghoon Kim Feb 2022

Heterogeneous Health Effects Of Medical Marijuana Legalization: Evidence From Young Adults In The United States, Junxing Chay, Seonghoon Kim

Research Collection School Of Economics

Legalizing marijuana for medical purposes is a longstanding debate. However, evidence of marijuana's health effects is limited, especially for young adults. We estimate the health impacts of medical marijuana laws (MML) in the U.S. among young adults aged 18–29 years using the difference-in-differences method and data from the Behavioral Risk Factors Surveillance System. We find that having MMLs with strict regulations generate health gains, but not in states with lax regulations. Our heterogeneity analysis results indicate that individuals with lower education attainments, with lower household income and without access to health insurance coverage gain more health benefits from MML with …

Perioperative Registries In Resource-Limited Settings: The Way Forward For Pakistan, Usama Waqar, Shaheer Ahmed, Ayesha Nasir Hameed, Namrah Aziz, Hina Inam

Medical College Documents

Capable of improving surgical quality, perioperative registries can allow performance benchmarking, reliable reporting and the development of risk-prediction models. Well established in high-income countries, perioperative registries remain limited in lower- and middle-income countries due to several challenges. First, ensuring comprehensive data entry forums to power the registries is difficult because of limited electronic medical records requiring sustained efforts to develop and integrate these into practice. Second, lack of adequate expertise and resources to develop and maintain registry software necessitates the involvement of software developers and information technology personnel.
