Catchem Before They Fall Through The Cracks: Implementation Of A Comprehensive Atherosclerosis Treatment Collaborative Health System Transition Of Care Multidisciplinary Clinic, Youssef Bessada, Taki Galanis, Brandi Thoma, Luis Eraso, Walter Kraft, Geno Merli, Dina Orapallo, Lynda Thomson, Heather Yenser

Pharmacy Presentations, Posters, and Grand Rounds

Introduction: Peripheral Artery Disease (PAD) is a common atherosclerotic cardiovascular (CV) disease that increases the risk for fatal and non-fatal CV events. Guidelines for the treatment of PAD recommend that in addition to necessary revascularization, general CV prevention with optimal medical therapy is of utmost importance and management is recommended to be multidisciplinary. While the prevalence of PAD in various practices is high, physician awareness of the PAD diagnosis is relatively low and the pharmacological component of preventative CV care is often underutilized resulting in patients receiving less intensive treatment. With new pharmacological agents, including advances in antithrombotic therapy, contributing …

Radiation Isolation And The Impact Of Care: Nursing Knowledge And Perception Of Radiation Risks, Bae P. Chu

Dissertations and Theses

Background: The safety challenges encountered when employing ionizing radiation to treat patients and manage radiation exposure and contamination have been well established in previous research. However, little is known about nurses’ understanding of the risks associated with ionizing radiation and how they respond to their own perceptions of risk. Although a wealth of literature shows an association between radiation treatment and negative patient experiences, there remains a lack of understanding of the basis of these perceptions among nurses. Increased ionizing radiation diagnoses and treatment means that nurses are at a higher risk of radiation exposure today than thirty years ago. …

Parasitism Of Corn Earworm, Helicoverpa Zea (Boddie) (Lepidoptera: Noctuidae), By Tachinid Flies In Cultivated Hemp, Armando Falcon-Brindis, John O. Stireman Iii, Zenaida J. Viloria, Raul T. Villanueva

Biological Sciences Faculty Publications

In a survey on hemp grown in western Kentucky we found an average of 27.8 CEW larvae per plant. We recorded 45% parasitism of CEW in these fields by two species of tachinid flies, Winthemia rufopicta and Lespesia aletiae. Most parasitized larvae were third to sixth instars at the time of collection. We found up to 22 tachinid eggs per host larva, 89% of which typically bore between 1 and 5 eggs on the thorax. 45.9% of CEW bearing eggs died. The number of tachinid eggs per host was unrelated to host body mass, but both the number of tachinid …

Allan, Christopher J. Guenthner, Bryce M. Meerhaeghe, Brian Borsari, Donna M. Kazemi Phd, Rn, Cne, Fiaan, Lindsay M. Orchowski

Faculty Publications

This study examines hazing among a sample of young male service members in the United States (US) military. Individual semi-structured interviews were conducted with active duty service members (N = 10) aged 18 to 24 at a large Southeastern US Army post to examine their conceptualization of hazing. Thematic analysis revealed three emergent themes: (1) the definition of hazing and hazing behaviors; (2) the ritualistic nature of hazing; and (3) the sexual nature of hazing. Most participants provided their own definition of hazing. One participant had difficulty in differentiating between hazing and bullying, the others had distinct definitions as …

Evaluation Of Surgical Skill Using Machine Learning With Optimal Wearable Sensor Locations, Rahul Soangra, R. Sivakumar, E. R. Anirudh, Sai Viswanth Reddy Y., Emmanuel B. John

Physical Therapy Faculty Articles and Research

Evaluation of surgical skills during minimally invasive surgeries is needed when recruiting new surgeons. Although surgeons’ differentiation by skill level is highly complex, performance in specific clinical tasks such as pegboard transfer and knot tying could be determined using wearable EMG and accelerometer sensors. A wireless wearable platform has made it feasible to collect movement and muscle activation signals for quick skill evaluation during surgical tasks. However, it is challenging since the placement of multiple wireless wearable sensors may interfere with their performance in the assessment. This study utilizes machine learning techniques to identify optimal muscles and features critical for …

Patched 1 Regulates Smoothened By Controlling Sterol Binding To Its Extracellular Cysteine-Rich Domain, Laurel Mydock-Mcgrane, Kathiresan Krishnan, Douglas F Covey, Et Al

2020-Current year OA Pubs

Smoothened (SMO) transduces the Hedgehog (Hh) signal across the plasma membrane in response to accessible cholesterol. Cholesterol binds SMO at two sites: one in the extracellular cysteine-rich domain (CRD) and a second in the transmembrane domain (TMD). How these two sterol-binding sites mediate SMO activation in response to the ligand Sonic Hedgehog (SHH) remains unknown. We find that mutations in the CRD (but not the TMD) reduce the fold increase in SMO activity triggered by SHH. SHH also promotes the photocrosslinking of a sterol analog to the CRD in intact cells. In contrast, sterol binding to the TMD site boosts …

Molecular Imaging Phenotyping For Selecting And Monitoring Radioligand Therapy Of Neuroendocrine Neoplasms, Amir Iravani, Ashwin Singh Parihar, Timothy Akhurst, Rodney J Hicks

2020-Current year OA Pubs

Neuroendocrine neoplasia (NEN) is an umbrella term that includes a widely heterogeneous disease group including well-differentiated neuroendocrine tumours (NETs), and aggressive neuroendocrine carcinomas (NECs). The site of origin of the NENs is linked to the intrinsic tumour biology and is predictive of the disease course. It is understood that NENs demonstrate significant biologic heterogeneity which ultimately translates to widely varying clinical presentations, disease course and prognosis. Thus, significant emphasis is laid on the pre-therapy evaluation of markers that can help predict tumour behavior and dynamically monitors the response during and after treatment. Most well-differentiated NENs express somatostatin receptors (SSTRs) which …

FZR1, which encodes the Cdh1 subunit of the anaphase-promoting complex, plays an important role in neurodevelopment by regulating the cell cycle and by its multiple post-mitotic functions in neurons. In this study, evaluation of 250 unrelated patients with developmental and epileptic encephalopathies and a connection on GeneMatcher led to the identification of three de novo missense variants in FZR1. Whole-exome sequencing in 39 patient-parent trios and subsequent targeted sequencing in an additional cohort of 211 patients was performed to identify novel genes involved in developmental and epileptic encephalopathy. Functional studies in Drosophila were performed using three different mutant alleles of …

Psychobiology Of Resilience, Rosarina A. J. Pelikan

DNP Qualifying Manuscripts

Nurse managers experience high levels of stress due to the complex bureaucratic and chaotic nature of the job, which can lead to burnout. In nurse managers, burnout negatively impacts the ability to meet the strategic goals of the quadruple aim: patient quality, patient satisfaction, cost savings, and employee well-being. Strategies to address burnout include minimizing or removing unnecessary causes of stress and provide the skills to protect against burnout. Resilience is a competency nurse leaders must have to withstand overwhelming job-related stress. Resilience-enhancing strategies have psychobiologic underpinnings and can be easily incorporated into nurse managers’ work schedules.

Assessment Of Spatial And Temporal Trends Of Exposure To Ambient Fine Particulate Matter And Ozone In New York/New Jersey Metropolitan Area, Subraham Singh

Dissertations and Theses

Background. Exposures to fine particulate matter (PM_2.5; particles with diameter less than 2.5 μm) and ozone (O₃) affect premature respiratory and cardiovascular mortality, morbidity and contribute to the development and progression of sub-clinical and clinical disease. Climate change affects air quality directly by modifying the thermodynamic properties of formation mechanisms and transport patterns, and indirectly, through increased emissions of PM_2.5 and O₃ precursors. The resultant changes in air quality influence human health outcomes through mechanisms of varying scale, timing, and complexity. PM_2.5 and O₃ levels have been declining due to the implementation …

Neighborhood Predictors Of E-Cigarette Retailer Density In New York City, Laena Orkin-Prol

Dissertations and Theses

Background: The rampant expansion of the e-cigarette market over the last decade in the U.S. is a threat to the health of the public—due to the e-cigarette’s appeal to young people, addictiveness, and harms of consumption. It is vital to study the distribution of e-cigarette retailers of different types in major urban centers, such as New York City (NYC), to identify if certain neighborhoods are overburdened with retailers and if intervention is required. The current research on the e-cigarette retailer environment is limited in its scope and methods used.

Objective: To investigate neighborhood attributes associated with e-cigarette retailer density in …

Biostatistics Collaborative Core: Faculty Publications and Other Works

Black men treated with frontline therapies for metastatic prostate cancer (MPC) show better clinical outcomes than non-Black men receiving similar treatments. Variations in body composition may contribute to these findings. However, preliminary data are required to support this concept. We conducted a retrospective cohort study for all men with MPC evaluated at our center over a 4-year period, collecting demographic and clinical data (N = 74). Of these, 55 men had diagnostic computed tomography images to quantify adipose tissue and skeletal muscle, specifically sarcopenia and myosteatosis. Nineteen men had repeat imaging to explore changes over time. Frequencies, medians, interquartile ranges, …

Factors Related To Contraceptive Use And Family Planning Decision-Making In The South Asian Community Residing In New York City, Nandini Shroff

Dissertations and Theses

Introduction: Currently, there are approximately 5.4 million South Asians residing in the United States (U.S.). The limited literature illustrates that contraceptive use is underutilized among Asians and Asian sub-groups, including South Asian Americans, compared to other racial and ethnic groups. Using Los Angeles County Health survey data, one study found that 22% of Asian Americans reported always using condom in the past 12 months compared to 37% of African Americans, 27% of Whites, and 27% of Hispanics. A study among New Jersey women revealed that compared to non-South Asian women, South Asians (SAs) were less likely to have used ever …

Investigation Of The Association Of Exposures To Fire-Related Hazards With Pulmonary Function Of Firefighters, David G. Goldfarb

Dissertations and Theses

Background. Firefighters are habitually exposed to hazardous toxicants which place them at an elevated risk for numerous adverse health outcomes. An example of this is the associations observed in other works between inhalation of combustion byproducts from urban structural fires and both acute and chronic pulmonary dysfunction. To-date, the characterization of firefighters’ exposures to dangerous chemicals in smoke from non-wildfire incidents, both directly through personal monitoring and indirectly from work-related records is scarce. Prior works investigating the association between routine firefighting and pulmonary function have relied on crude metrics such as years of service and numbers of responses to …

Current publicly available tools that allow rapid exploration of linkage disequilibrium (LD) between markers (e.g., HaploReg and LDlink) are based on whole-genome sequence (WGS) data from 2,504 individuals in the 1000 Genomes Project. Here, we present toP-LD, an online tool to explore LD inferred with high-coverage (∼30×) WGS data from 15,578 individuals in the NHLBI Trans-Omics for Precision Medicine (TOPMed) program. toP-LD provides a significant upgrade compared to current LD tools, as the toPMed WGS data provide a more comprehensive representation of genetic variation than the 1000 Genomes data, particularly for rare variants and in the specific populations that we …

Macrophages Disseminate Pathogen Associated Molecular Patterns Through The Direct Extracellular Release Of The Soluble Content Of Their Phagolysosomes, Catherine J Greene, Jenny A Nguyen, Samuel M Cheung, Corey R Arnold, Dale R Balce, Ya Ting Wang, Adrian Soderholm, Neil Mckenna, Devin Aggarwal, Rhiannon I Campden, Benjamin W Ewanchuk, Herbert W Virgin, Robin M Yates

2020-Current year OA Pubs

Recognition of pathogen-or-damage-associated molecular patterns is critical to inflammation. However, most pathogen-or-damage-associated molecular patterns exist within intact microbes/cells and are typically part of non-diffusible, stable macromolecules that are not optimally immunostimulatory or available for immune detection. Partial digestion of microbes/cells following phagocytosis potentially generates new diffusible pathogen-or-damage-associated molecular patterns, however, our current understanding of phagosomal biology would have these molecules sequestered and destroyed within phagolysosomes. Here, we show the controlled release of partially-digested, soluble material from phagolysosomes of macrophages through transient, iterative fusion-fission events between mature phagolysosomes and the plasma membrane, a process we term eructophagy. Eructophagy is most active …

UNLABELLED: Cancer cells depend on multiple driver alterations whose oncogenic effects can be suppressed by drug combinations. Here, we provide a comprehensive resource of precision combination therapies tailored to oncogenic coalterations that are recurrent across patient cohorts. To generate the resource, we developed Recurrent Features Leveraged for Combination Therapy (REFLECT), which integrates machine learning and cancer informatics algorithms. Using multiomic data, the method maps recurrent coalteration signatures in patient cohorts to combination therapies. We validated the REFLECT pipeline using data from patient-derived xenografts, in vitro drug screens, and a combination therapy clinical trial. These validations demonstrate that REFLECT-selected combination therapies …

Utilizing an exemplar socio-cultural topic, we studied the feasibility of achieving expert consensus among two groups of faculty (experts in medical education and experts in social determinants of health) on which aspects of the topic could be taught during undergraduate versus graduate medical education.

METHODS: A modified Delphi method was used to generate expert consensus on which learning objectives of social determinants of health are best taught at each stage of medical education. Delphi respondents included experts in medical …

Pathological Response And Immune Biomarker Assessment In Non-Small-Cell Lung Carcinoma Receiving Neoadjuvant Immune Checkpoint Inhibitors, Frank Rojas, Edwin Roger Parra, Ignacio Ivan Wistuba, Cara Haymaker, Luisa Maren Solis Soto

Faculty, Staff and Student Publications

Lung cancer is the leading cause of cancer incidence and mortality worldwide. Adjuvant and neoadjuvant chemotherapy have been used in the perioperative setting of non-small-cell carcinoma (NSCLC); however, the five-year survival rate only improves by about 5%. Neoadjuvant treatment with immune checkpoint inhibitors (ICIs) has become significant due to improved survival in advanced NSCLC patients treated with immunotherapy agents. The assessment of pathology response has been proposed as a surrogate indicator of the benefits of neaodjuvant therapy. An outline of recommendations has been published by the International Association for the Study of Lung Cancer (IASLC) for the evaluation of pathologic …
