Molecular Typing Of Rickettsia Akari, Marina E. Eremeeva

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

Rickettsia akari is an obligate intracellular bacterium that causes smallpox rickettsia. Rickettsia akari is an atypical member of the rickettsia spotted fever (SFG) group because it circulates in gamasid mites; however, only limited data are available regarding the degree of genetic diversity of R. akari isolates. We examined 13 isolates of R. akari isolated from humans, rodents, and ticks in the United States, the countries of the former USSR, and the former Yugoslavia for the period from 1946 to 2003 for diversity in the composition of tandem repeats (TR) and intergenic regions (IGR). Using the Tandem Repeat Finder software (http://tandem.bu.edu) …

Distribution Of Human Exposure To Ozone During Commuting Hours In Connecticut Using The Cellular Device Network, Owais Gilani, Simon Urbanek, Michael J. Kane

Faculty Journal Articles

Epidemiologic studies have established associations between various air pollutants and adverse health outcomes for adults and children. Due to high costs of monitoring air pollutant concentrations for subjects enrolled in a study, statisticians predict exposure concentrations from spatial models that are developed using concentrations monitored at a few sites. In the absence of detailed information on when and where subjects move during the study window, researchers typically assume that the subjects spend their entire day at home, school, or work. This assumption can potentially lead to large exposure assignment bias. In this study, we aim to determine the distribution of …

Transcriptional Insights Into Pathogenesis Of Cutaneous Systemic Sclerosis Using Pathway Driven Meta-Analysis Assisted By Machine Learning Methods, Xiao Xu, Meera Ramanujam, Sudha Visvanathan, Shervin Assassi, Zheng Liu, Li Li

Journal Articles

Pathophysiology of systemic sclerosis (SSc, Scleroderma), an autoimmune rheumatic disease, comprises of mechanisms that drive vasculopathy, inflammation and fibrosis. Understanding of the disease and associated clinical heterogeneity has advanced considerably in the past decade, highlighting the necessity of more specific targeted therapy. While many of the recent trials in SSc failed to meet the primary end points that predominantly relied on changes in modified Rodnan skin scores (MRSS), sub-group analysis, especially those focused on the basal skin transcriptomic data have provided insights into patient subsets that respond to therapies. These findings suggest that deeper understanding of the molecular changes in …

Articles, Abstracts, and Reports

Prostate cancer (PCa) is a major serious malignant tumor and is commonly diagnosed in older men. Identification of novel cancer-related genes in PCa is important for understanding its tumorigenesis mechanism and developing new therapies against PCa. Here, we used RNA sequencing to identify the specific genes, which are upregulated in PCa cell lines and tissues. The cell division cycle associated protein (CDCA) family, which plays a critical role in cell division and proliferation, is upregulated in the PCa cell lines of our RNA-Sequencing data. Moreover, we found that CDCA2 is overexpressed, and its protein level positively correlates with its histological …

Clinical Outcomes Of Orofacial Myofunctional Therapy In Children Without Concurrent Orthodontia, Julia Logan

Graduate Research Papers

Purpose: Orofacial Myofunctional Therapy (OMT) addresses impairments in breathing, swallowing, chewing, and/or speech by eliminating maladaptive oral behaviors (e.g., poor position of the tongue and noxious habits); however, there is little evidence regarding its clinical effectiveness separate from concurrent orthodontia. The present study sought to explore early changes in tongue strength, dentition/palatal shape, and orofacial behaviors following OMT in the absence of orthodontic treatment.

Rickettsialpox – A Rare But Not Extinct Disease: A Review Of The Literature And New Directions, Marina Eremeeva, Kamalich Muniz-Rodriguez

Department of Biostatistics, Epidemiology, and Environmental Health Sciences Faculty Publications

Smallpox rickettsia is an urban zoonosis caused by Rickettsia akari. To date, R. akari is the only characterized representative of the group of spotted fevers transmitted by the gamasid mite Liponyssoides sanguineus, which is common among peridomic rodents. This disease was first described in New York in 1946, and a few years later a similar outbreak occurred in the Ukrainian SSR. Numerous serological studies and diagnostics of sporadic cases of smallpox rickettsiosis suggest its widespread occurrence on the planet; however, the current geography and incidence of smallpox rickettsiosis is unknown. Smallpox rickettsiosis is characterized by the classic clinical triad of …

2020-Current year OA Pubs

BACKGROUND: Implementing and sustaining evidence-based programs with fidelity may require multiple implementation strategies tailored to address multi-level, context-specific barriers and facilitators. Ideally, selecting and tailoring implementation strategies should be guided by theory, evidence, and input from relevant stakeholders; however, methods to guide the selection and tailoring of strategies are not well-developed. There is a need for more rigorous methods for assessing and prioritizing implementation determinants (barriers and facilitators) and linking implementation strategies to determinants. The Collaborative Organizational Approach to Selecting and Tailoring Implementation Strategies (COAST-IS) is an intervention designed to increase the effectiveness of evidence-based practice implementation and sustainment. COAST-IS …

The Legal And Medical Necessity Of Abortion Care Amid The Covid-19 Pandemic, Greer Donley, Beatrice Chen, Sonya Borrero

Articles

In response to the COVID-19 pandemic, states have ordered the cessation of non-essential healthcare. Unfortunately, many conservative states have sought to capitalize on those orders to halt abortion care. In this short paper, we argue that abortion should not fall under any state’s non-essential healthcare order. Major medical organizations recognize that abortion is essential healthcare that must be provided even in a pandemic, and the law recognizes abortion as a time-sensitive constitutional right. Finally, we examine the constitutional arguments as to why enforcing these orders against abortion providers should not stand constitutional scrutiny. We conclude that no public health purpose …

Parental Autonomy Over Prenatal End-Of-Life Decisions, Greer Donley

Articles

When parents learn that their potential child has a life-limiting, often devastating, prenatal diagnosis, they are faced with the first (and perhaps, only) healthcare decisions they will make for their child. Many choose to terminate the pregnancy because they believe it is in their potential child’s best interest to avoid a short and painful life. I argue that these decisions should be protected in the same way that parental healthcare decisions are constitutionally protected after birth—including a parent’s refusal or withdrawal of life-saving treatment for an infant or child who is very sick or dying. Parental autonomy ensures that parents …

A History Of The Law Of Assisted Dying In The United States, Alan Meisel

Articles

The slow growth in the number of states that have enacted legislation to permit what is often referred to as “death with dignity” legislation—and more frequently referred to popularly as “physician assisted suicide” laws—has begun to accelerate in the past few years since the enactment of the first such statute in Oregon in 1994.

Like much other social reform legislation, there is a long history behind it. In this case, the history in the United States dates back at least to the latter part of the nineteenth century. Not until the 1980s, however, did these efforts gain any traction in …
