Examining Cervical Cancer Screening Utilization Among African Immigrant Women: A Literature Review, Adebola Adegboyega, Mollie Aleshire, Ana Maria Linares

Faculty and Staff Scholarship

Background: Globally, 530,000 women per year are diagnosed with cervical cancer, and approximately 275,000 die from the disease. Routine cervical cancer screening may reduce the burden of cervical cancer morbidity and mortality through early detection and improved treatment outcome. Immigrant women in the United States (U.S.) may be disproportionately affected by cervical cancer; however, there is scarce literature addressing cervical cancer screening in African immigrants (AIs) when compared to other immigrant groups. This systematic review evaluates the state of cervical cancer screening research in AIs and identifies current gaps.

Materials and methods: Through a comprehensive literature search, we identified 16 …

The rapid development of genomic sequencing technologies has decreased the cost of genetic analysis to the extent that it seems plausible that genome-scale sequencing could have widespread availability in pediatric care. Genomic sequencing provides a powerful diagnostic modality for patients who manifest symptoms of monogenic disease and an opportunity to detect health conditions before their development. However, many technical, clinical, ethical, and societal challenges should be addressed before such technology is widely deployed in pediatric practice. This article provides an overview of the Newborn Sequencing in Genomic Medicine and Public Health Consortium, which is investigating the application of genome-scale sequencing …

Penetrance Estimates For Incidental Genomic Findings In Acmg-59, James A. Diao

Yale Day of Data

The dropping costs and rising popularity of next-generation sequencing has introduced the possibility of personalizing medical treatments and screening for genetic diseases. Still, the clinical community’s understanding remains incomplete, with limited consensus on the proper interpretation for many genetic variants. Thus, the standard procedure when returning sequencing results has been to report findings only in genes related to the diagnostic indication, and not incidental findings in other genes. To balance the threat of false positives with the medical benefits of true findings, the American College on Medical Genetics and Genomics (ACMG) recommends an exception: that clinical sequencing laboratories seek and …

Accurate prediction of Alzheimer’s disease (AD) is important for the early diagnosis and treatment of this condition. Mild cognitive impairment (MCI) is an early stage of AD. Therefore, patients with MCI who are at high risk of fully developing AD should be identified to accurately predict AD. However, the relationship between brain images and AD is difficult to construct because of the complex characteristics of neuroimaging data. To address this problem, we present a longitudinal measurement of MCI brain images and a hierarchical classification method for AD prediction. Longitudinal images obtained from individuals with MCI were investigated to acquire important …

Enhanced Breast Cancer Classification With Automatic Thresholding Using Support Vector Machine And Harris Corner Detection, Mohammad Taheri

Electronic Theses and Dissertations

Image classification and extracting the characteristics of a tumor are the powerful tools in medical science. In case of breast cancer medical treatment, the breast cancer classification methods can be used to classify input images as benign and malignant classes for better diagnoses and earlier detection with breast tumors. However, classification process can be challenging because of the existence of noise in the images, and complicated structures of the image. Manual classification of the images is timeconsuming, and need to be done only by medical experts. Hence using an automated medical image classification tool is useful and necessary. In addition, …

Halo- And Solvato-Fluorochromic Polymer Nanoassemblies For Cancer Theranostics, Derek Alexander Reichel

Theses and Dissertations--Pharmacy

Theranostics is an emerging treatment approach that combines diagnostics with therapy in order to personalize treatment regimens for individual patients and decrease cancer mortality. Previously, nanoparticles entrapping conventional fluorescent dyes were developed for cancer theranostics, but fluorescent nanoparticles did not allow clinicians to significantly improve cancer treatments.

The use of fluorescent dyes that are sensitive to solvent acidity (halo-fluorochromism) and polarity (solvato-fluorochromism) may overcome the limitations of fluorescent nanoparticles and improve cancer therapy by enabling researchers to detect chemical properties within the nanoparticle core environment. The model halo- and solvato-fluorochromic dye Nile blue was attached to the core of nanoscale …

We conducted a cross-sectional study using geocoded state cancer registry data. Using hierarchical multilevel logistic regression models we estimated ORs and 95% confidence intervals for the impact of socioeconomic, Hispanic ethnic concentration, index of dissimilarity, and health resource availability measures on LSMD. Results. We identified 12,493 cases. In California, late …

Biomarkers Of Sepsis: A Retrospective Approach, Jose M. Roberts

Williams Honors College, Honors Research Projects

Background: Biomarkers are taking the spotlight in becoming the norm for early diagnoses. Sepsis is an inflammatory disease that increases metabolic rate in children. The first biomarker is hyponatremia. Hyponatremia is a frequent electrolyte imbalance in clinical practice, often observed in children with inflammatory disease and infection. Presence of hyponatremia is associated with electrical signaling imbalances, inflammation and renal dysfunction. The clinical value of hyponatremia in pediatric patients is unknown. The C-reactive protein is a second biomarker. Its presence signifies that necrotic cells and inflammation are present.

Objectives: To evaluate the use of biomarkers in children seen in the Emergency …

Concerns About Justification For Fetal Genome Sequencing, Leslie Francis

Utah Law Faculty Scholarship

The proposal by Chen and Wasserman (2017) contributes to a long-standing debate about the scope of prenatal screening services. With realistic prospects of fetal genome-scale sequencing from noninvasive maternal blood sampling (NIPW), their framework is timely. However, we outline a number of concerns regarding this approach, ranging from the philosophical to the social and clinical. A key concern in this literature is that the framework lacks a clear philosophical foundation. Despite the long history of prenatal diagnosis (PND), a central question remains regarding the core justification for these services.

The purpose of this study is to use 3-D imaging to the analyze the relationships among cervical spine angles, craniocervical posture, cervical spine length and the oropharyngeal airway volume in OSA patients in both the supine and upright positions.

Twenty-eight OSA subjects with 3-D imaging were included. Airway, craniocervical posture, spine angles, and spine length were assessed using Dolphin 11.8. Correlation analyses were utilized to detect associations among the recorded and measured variables. Mean differences were …

Investigations Into The Effects Of Water Exchange And The Structure Of Lanthanide Chelates, Katherine Marie Payne

Dissertations and Theses

Lanthanide chelates are effective agents for improving contrast in MR images. Optimizing the relaxation of inner sphere water molecules is a common focus of research in this field. However, the efforts to design an optimal contrast agent have commonly over-looked the relationship of water position and water exchange kinetics. This work explores structural conformation, the impact of very fast water exchange kinetics on hydration, and differing tumbling rates for regioisomers of a number of lanthanide chelates. We have grown crystals of LnDOTMA and obtained structural data by X-ray diffraction that provide a picture of the chelate during water exchange and …

Does The Electronic Health Record Improve The Timeliness Review And Notification Of Medical Laboratory And X-Ray Test Results?, Ruby Estes

Applied Research Projects

The medical community struggles with timeliness issues throughout the different healthcare environments in many areas of patient care. The demands of meeting patient care needs is great everywhere. One area that can lead to extreme adverse outcomes and affects patient safety is failure to review and follow-up on medical test results timely. In addition the lack of timely follow-up and treatment can lead to medico-legal implications for all healthcare professionals involved in the patients care. Some timeliness issues have been attributed to understaffed healthcare institutions, lack of trained staff, and in many instances inefficient and insufficient processes. This is an …

Late Onset Of Pulmonary Hypertension And Sepsis In Omphalocele Infants, Joanne E. Baerg, Arul Thirumoorthi, Whitney Carlton, Shelly Haug, Andrew O. Hopper, Donna Goff, Sandhya Ramlogan, Shawn D. St Peter

Manuscripts, Articles, Book Chapters and Other Papers

A subset of omphalocele infants has respiratory decompensation after the first week of life and PHN is diagnosed. Infection may initiate decompensation. In some, PHN is distinct from pulmonary hypoplasia as they oxygenate on room air for some time after birth. With aggressive treatment and follow-up, PHN can resolve. The late diagnosis of PHN in infants with omphalocele is previously unappreciated and deserves further study.

Can Bedside Ultrasound Inferior Vena Cava Measurements Accurately Diagnose Congestive Heart Failure In The Emergency Department? A Clin-Iq, Miranda Gaskamp, Mark Blubaugh, Laine H. Mccarthy, Dewey C. Scheid

Journal of Patient-Centered Research and Reviews

Congestive heart failure (CHF) is a major cause of morbidity and mortality. Early diagnosis of CHF in patients presenting to the emergency department with undifferentiated dyspnea would allow clinicians to begin appropriate treatment more promptly. Current guidelines recommend B-type natriuretic peptide (BNP) levels for more accurate diagnosis of CHF in dyspneic patients. Although BNP levels are relatively inexpensive, the test is not usually performed at bedside and results may take up to an hour or more. BNP also may have a “gray zone” in which the values can neither confirm nor rule out CHF. BNP has a reported sensitivity of …
