Incidence And Potential Co-Morbidities In Facial Pigmentary Demarcation Lines In Indian Populations, Lakkireddygari Sujana, Savitha L. Beergouder, Alekhya Rallapalli, Sujatha Alla, Prasanthi Chidipudi Jan 2022

Incidence And Potential Co-Morbidities In Facial Pigmentary Demarcation Lines In Indian Populations, Lakkireddygari Sujana, Savitha L. Beergouder, Alekhya Rallapalli, Sujatha Alla, Prasanthi Chidipudi

Engineering Management & Systems Engineering Faculty Publications

Background: The most noticeable part of human body is face. The obvious boundaries on the skin known as Pigmentary Demarcation Lines (PDL) found over face and have clear borders of abrupt transition between more hyper-pigmented skin and areas of normal skin pigmentation due to differences in melanocyte distribution that may be influenced by multiple factors. Facial pigmentary demarcation lines (PDL) directly reflect on patient’s physical appearance and self-image as they may contribute to dysmorphism and even central to depressive illness in susceptible individuals posing cosmetic concern for the patient and a challenge for dermatologist. Therefore, it is important for early …

Cholera Transmission Dynamic Model With Environmental Impacts Of Plankton Reservoirs, Sweety Sarker Jan 2022

Cholera Transmission Dynamic Model With Environmental Impacts Of Plankton Reservoirs, Sweety Sarker

Electronic Theses and Dissertations, 2020-2023

Cholera is an acute disease that is a global threat to the world and can kill people within a few hours if left untreated. In the last 200 years, seven pandemics occurred, and, in some countries, it remains endemic. The World Health Organization (WHO) declared a global initiative to prevent cholera by 2030. Cholera dynamics are contributed by several environmental factors such as salinity level of water, water temperature, presence of plankton especially zooplankton such as cladocerans, rotifers, copepods, etc. Vibrio cholerae (V. cholerae) bacterium is the main reason behind the cholera disease and the growth of V. cholerae depends …

Reexamining Cytolethal Distending Toxin's Host Cell Entry And Trafficking: The First Steps Down A Long Road, George Huhn Jan 2022

Reexamining Cytolethal Distending Toxin's Host Cell Entry And Trafficking: The First Steps Down A Long Road, George Huhn

Electronic Theses and Dissertations, 2020-2023

Cytolethal distending toxin (CDT) is a virulence factor produced by many Gram-negative bacteria, including Haemophilus ducreyi, the causative agent of genital chancroid. CDT is a heterotrimeric toxin consisting of a cell-binding domain (CdtA + CdtC) and a catalytic domain (CdtB) that has DNase activity. After binding to the host plasma membrane, CDT undergoes endocytosis and travels through the endosomes en route to the endoplasmic reticulum (ER). Only CdtB and CdtC arrive in the Golgi before moving to the ER. Only then does CdtB move into the nucleus, causing DNA damage that induces cell-cycle arrest and apoptosis. The previous CDT trafficking …

Continuing Medical Education On Immunothombosis In Sepsis, Vivienne Van Nguyen Jan 2022

Continuing Medical Education On Immunothombosis In Sepsis, Vivienne Van Nguyen

Capstone Showcase

In the past decades, the incidence of sepsis complicated by immunothrombosis has increased in critically ill patients, especially those with sepsis and septic shock. Despite intensive surveillance and prevention of the underlying causes, these disease syndromes are frequently fatal. The increased incidence of immunothrombosis in sepsis has been accompanied by many critical issues and concerns regarding current diagnostic and treatment protocols. This paper offers a concise critical assessment of the current state of knowledge about sepsis and immunothrombosis among clinicians in the ICU as well as problem concerning the recognition of sepsis and immunothrombosis and their management.

Antibiotic Permeation In Gram-Negative Bacteria And Contribution Of Inflammasome Activation And Pyroptosis In Pathogenesis Of Salmonella Systemic Infection, Ankit Pandeya Jan 2022

Antibiotic Permeation In Gram-Negative Bacteria And Contribution Of Inflammasome Activation And Pyroptosis In Pathogenesis Of Salmonella Systemic Infection, Ankit Pandeya

Theses and Dissertations--Chemistry

Antibiotic resistance is one of the major global issues in the field of public health and medicine. Good antibiotic candidates need to be selectively toxic, inhibit cellular target, and effectively penetrate and accumulate in bacterial cells. The last factor is a formidable barrier in the development of antimicrobials effective in Gram-negative bacteria, due to the presence of two layers of cell envelope. The first half of my thesis focuses on understanding the permeation of small molecules through this formidable cell envelope, distribution inside the cell of Gram-negative bacteria, and design of novel methods to make small molecules effectively cross the …

Nicotine And Cotinine: Microbial Modulators Of The Immune Response, Jourdan Lakes Jan 2022

Nicotine And Cotinine: Microbial Modulators Of The Immune Response, Jourdan Lakes

Theses and Dissertations--Chemistry

The consumption of tobacco products is a known contributor to a variety of health conditions and disease pathologies including cardiovascular and lung diseases. In addition to these well-known pathological effects of tobacco use, it has been established recently that tobacco consumption as well as nicotine consumption alone results in distinct, dysbiotic perturbations to the enteric microflora of the gastrointestinal tract. Previous research into the intestinal microbiome has demonstrated that these microbes are active contributors to the maintenance of a homeostatic and tolerogenic environment within the host. In fact, the presence of our enteric microflora is necessary for the proper development …

Associations Between Eight Earth Observation-Derived Climate Variables And Enteropathogen Infection: An Independent Participant Data Meta-Analysis Of Surveillance Studies With Broad Spectrum Nucleic Acid Diagnostics, Josh M.

Diarrheal disease, still a major cause of childhood illness, is caused by numerous, diverse infectious microorganisms, which are differentially sensitive to environmental conditions. Enteropathogen‐specific impacts of climate remain underexplored. Results from 15 studies that diagnosed enteropathogens in 64,788 stool samples from 20,760 children in 19 countries were combined. Infection status for 10 common enteropathogens—adenovirus, astrovirus, norovirus, rotavirus, sapovirus, Campylobacter, ETEC, Shigella, Cryptosporidium and Giardia—was matched by date with hydrometeorological variables from a global Earth observation dataset—precipitation and runoff volume, humidity, soil moisture, solar radiation, air pressure, temperature, and wind speed. Models were fitted for each pathogen, accounting …

Improving Disinfectant Cap Use On Central Lines In The Icu To Reduce Patient Risk For Clabsi: A Quality Improvement Project, Tali Cherim Jan 2022

Improving Disinfectant Cap Use On Central Lines In The Icu To Reduce Patient Risk For Clabsi: A Quality Improvement Project, Tali Cherim

Master's Theses and Capstones

BACKGROUND: Central line-associated bloodstream infections (CLABSI) are the most common type of preventable healthcare-associated bloodstream infection, and may increase length of stay (LOS), facility treatment costs, and patient mortality rates. Intensive Care Unit (ICU) patients are especially vulnerable to CLABSI due to their critical health conditions and other comorbid factors. A literature review provided evidence supporting the use of alcohol-impregnated disinfectant caps, such as SwabCap®, on central line (CL) ports to significantly reduce patients’ risk for CLABSI. This quality improvement project took place within an adult ICU of a Level II trauma facility in New England, where the Infection Prevention …
