Radioluminescence Based Biochemical Sensing And Imaging Strategies To Measure Local Drug Release And Ph, Gretchen B. Schober Aug 2022

Radioluminescence Based Biochemical Sensing And Imaging Strategies To Measure Local Drug Release And Ph, Gretchen B. Schober

All Dissertations

In this dissertation we describe methods for measuring infection relevant biochemical analytes using radioluminescent and ultrasound luminescent materials. Films and nanoparticles fabricated with europium doped gadolinium oxysulfide (Gd2O2S:Eu3+) are used to quantitatively measure radiolabeled pharmaceutical concentration, specifically tritium labeled vancomycin (3H-vancomycin). Europium and dysprosium doped strontium aluminate is used to fabricate an ultrasound modulated, pH sensing film. These methods are indicated for theranostic evaluation of implant associated infection. Bacterial biofilms are inherently resistant to traditional antibiotic treatment and can coat biomedical implants. These biofilm related infections are difficult or impossible to eradicate …

Laboratory-Reported Normal Value Ranges Should Not Be Used To Diagnose Periprosthetic Joint Infection., Salvador A. Forte, Joseph A. D'Alonzo, Zachary Wells, Brett Levine, Stephen Sizer, Carl Deirmengian

Orthopedic Surgery Resident Research

INTRODUCTION: Clinical laboratories offer several multipurpose tests, such as the erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP), which are not intended to diagnose any specific disease but are used by clinicians in multiple fields. The results and laboratory interpretation (normal/abnormal) of these multipurpose tests are based on laboratory-reported normal thresholds, which vary across clinical laboratories. In 2018, the International Consensus Meeting on Musculoskeletal Infection (2018 ICM) provided a gold-standard definition to diagnose periprosthetic joint infection (PJI) which included many multipurpose laboratory tests, along with thresholds optimized to diagnose PJI. The discrepancy between laboratory-reported normal thresholds and 2018 ICM-recommended PJI-optimized …

All Dugoni School of Dentistry Faculty Articles

Boswellia trees, found throughout the Middle East and parts of Africa and Asia, are the source of frankincense oil. Since antiquity, frankincense has been traded as a precious commodity, but it has also been used for the treatment of chronic disease, inflammation, oral health, and microbial infection. More recently, the bioactive components of Boswellia trees have been identified and characterized for their effects on cancer, microbial infection (especially infection by oral pathogens), and inflammation. Most studies have focused on cell lines, but more recent research has also investigated effects in animal models of disease. As natural products are considered to …


Update In Laboratory Diagnosis Of Urinary Tract Infection, Weny Rinawati, Diana Aulia Jun 2022

Update In Laboratory Diagnosis Of Urinary Tract Infection, Weny Rinawati, Diana Aulia

Jurnal Penyakit Dalam Indonesia

Urinary tract infection (UTI) is an infection caused by the entry of pathogens into the urinary tract. Symptoms of a UTI are not always obvious, and some are asymptomatic or atypical. Urinary tract infections must be distinguished from other diseases that have a similar clinical appearance. Many UTIs resolve spontaneously, but often cause significant morbidity and mortality. With the unpredictable nature of the disease, laboratory tests are required for accurate diagnosis and identification of the cause of infection. Thus, it is necessary to understand the interpretation and limitations of urinalysis and urine culture results. To assist in the diagnosis of …

Resolving The Repression Pathway Of Virulence Gene Hila In Salmonella, Alexandra King, Lon Chubiz Phd, Brenda Pratte, Lauren Daugherty

Undergraduate Research Symposium

Salmonella is a relatively abundant, virulent species of bacteria that is most known for spreading gastrointestinal diseases through food. These illnesses result in approximately 1.35 million infections, including over 25,000 hospitalizations each year, in the U.S. alone (CDC.gov). As antibiotic resistance becomes an increasingly urgent public health problem, the importance of developing alternative treatment methods is only becoming more crucial. One of the genes responsible for this virulence is known as hilA. HilA is the main transcriptional regulator of Salmonella Pathogenicity Island-1 gene (UniProt). SPI-1 plays an important role in the invasion of Salmonella into epithelial cells. The proteins encoded …

Improving Patient Outcomes One Warm Patient At A Time, Lindsey King, Marcus Austin Robison, Julie Bonom Dnp, Michael Godbold Md

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

Patient Temperature measurement postoperatively reveals that hypothermia occurs in surgical patients 25-90% of the time. Unintended perioperative hypothermia can be linked to many negative patient outcomes such as increased incidence of surgical site infection (SSI), delayed wound healing and increased length of hospital stay, to mention a few. Any single or combination of the aforementioned issues can eventually lead to an increase in patient morbidity and mortality. The purpose of this proposed quality practice improvement project is to increase the compliance of hypothermia prevention strategies, specifically forced air warming, at the implementation site. The targeted practice improvement is aimed at …

Quality Improvement: Education And Implementation Of Proper Narcotic Handling Practices By Nurse Anesthetists, Shelby Stevenson, Anne Hendershott, Alexis Asprah, Julie Bonom

Graduate Publications and Other Selected Works - Doctor of Nursing Practice (DNP)

Medication errors are estimated to occur once in every 150-300 surgeries (Wahr et al., 2017, p. 36). Unsafe injection practices can lead to increased morbidity and mortality, diminish the overall quality of life for patients, and contribute to substantial increases in healthcare costs. A large majority of unsafe injection practices are caused by a lack of education or mistaken beliefs regarding safe injection practices. Educational reinforcement of safe narcotic handling techniques has significant potential to increase the appropriate use of narcotic syringes among nurse anesthesia providers. The long-standing impact of this project could lead to a reduced number of ‘never …

Dnp Final Report: Using Standardized Surgical Bundles To Reduce Post Cesarean Section Infection: An Evidence-Based Practice Project, Amy L. Wagner

DNP Final Reports

A new mother has so many stressors and a post cesarean section infection should never have to be one of them. The infection rate at MHTW is double the national average at 1.85. This evidence-based practice project looks at the implementation of a pre-surgical bundle in women undergoing cesarean section to reduce overall risk of developing a post cesarean section infection. This evidence shows that the combination of a standardized bundle including infection specific education for the patient and family, pre- and post-surgical bathing, elimination of jewelry worn by patients and staff, antibiotic timing, Chlorhexidine skin prep, and a vaginal …

The Three-Way Interplay Among Early Life Exposures, The Gut Microbiome, And Outcomes In Infancy, Yuka Moroishi

Dartmouth College Ph.D Dissertations

The bidirectional relationship between the gut microbiome and immune system plays an important role in host immune status: the immune system provides the gut microbiome the optimal environment to thrive in, and the gut microbiome helps regulate the immune system. This relationship is especially important in infants, whose immune system is still premature and rely on innate immunity.

We investigated the three-way interplay among early-life exposures, the developing gut microbiome, and outcomes in infancy from the general population in New Hampshire, US. We used prospective cohort data from the New Hampshire Birth Cohort study to 1) determine whether timing of …


Exploring Epigenetic Reprogramming During Central Nervous System Infection, Zachary Van Roy, Tammy Kielian Jan 2022

Exploring Epigenetic Reprogramming During Central Nervous System Infection, Zachary Van Roy, Tammy Kielian

Journal Articles: Pathology and Microbiology

Epigenetics involves the study of various modes of adaptable transcriptional regulation, contributing to cell identity, characteristics, and function. During central nervous system (CNS) infection, epigenetic mechanisms can exert pronounced control over the maturation and antimicrobial properties of nearly every immune cell type. Epigenetics is a relatively new field, with the first mention of these marks proposed only a half-century ago and a substantial body of immunological epigenetic research emerging only in the last few decades. Here, we review the best-characterized epigenetic marks and their functions as well as illustrate how various immune cell populations responding to CNS infection utilize these …

The scientific, private, and industrial sectors use a wide variety of technological platforms available to achieve protection against SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), including vaccines. However, the virus evolves continually into new highly virulent variants, which might overcome the protection provided by vaccines and may re-expose the population to infections. Mass vaccinations should be continued in combination with more or less mandatory non-pharmaceutical interventions. Therefore, the key questions to be answered are: (i) How to identify the primary and secondary infections of SARS-CoV-2? (ii) Why are neutralizing antibodies not long-lasting in both cases of natural infections and post-vaccinations? …

Identification Of Subclinical Iron Deficiency Using New Erythrocytes, Leukocytes, And Reticulocytes Parameters During Nonsevere Acute Infection In Pediatric Outpatients, Nazmi̇ Mutlu Karakaş, Serap Ki̇rki̇z Kayali, Zühre Kaya

Turkish Journal of Medical Sciences

Background/aim: This study aims to investigate the diagnostic utility of new erythrocytes, leukocytes, and reticulocytes parameters for the identification of subclinical iron deficiency (ID) in children under 6 years with nonsevere acute infection in pediatric outpatients. Materials and methods: The study included 102 children with acute infections and 31 true ID. Traditional and new hematology parameters were measured in a Sysmex-XN® , along with C-reactive protein level, and iron parameters. Participants? ID were categorized as: the ferritin < 100 ng/mL, transferrin saturation < 20% was defined as ?subclinical or functional ID (FID) in Group 1?; ferritin < 30 ng/mL, transferrin saturation < 20%, as ?absolute-ID (AID)? in Group 2; ferritin < 12 ng/mL without anemia and infection, as ?true ID? in Group 3. Results: The frequencies of FID and AID among the 102 children with acute infection were 24% and 76%, respectively. Compared with the Group 2 patients, Group 1 had a significantly higher mean percentage of hypochromic erythrocytes (Hypo-He), and significantly lower levels of hemoglobin (Hb) and Hb content of reticulocytes (RET-He) (p < 0.05 for all). Compared with Group 2 and Group 3 patients, Group 1 had a significantly higher mean percentage of immature reticulocyte fraction (IRF) and immature granulocyte (IG) values (p < 0.05 for all). The RET-He, IRF%, Hypo-He%, and IG% cut-off values for predicting FID during infection were 27.0 pg, 10.6%, 2.5%, and 0.35% respectively. Conclusion: The RET-He, Hypo-He, IRF, and IG may be useful parameters for identifying subclinical ID in small children with nonsevere acute infection in pediatric outpatients.
