Association Of Natural Waterways And Legionella Pneumophila Infection In Eastern Wisconsin: A Case-Control Study, Hannah M. William, Kayla Heslin, Jessica J. F. Kram, Caroline P. Toberna, Dennis J. Baumgardner

Journal of Patient-Centered Research and Reviews

Preliminary research has suggested possible associations between natural waterways and Legionella infection, and we previously explored these associations in eastern Wisconsin using positive L. pneumophila serogroup 1 urine antigen tests (LUAT) as diagnostic. This case-control study was a secondary analysis of home address data from patients who underwent LUAT at a single eastern Wisconsin health system from 2013 to 2017. Only zip codes within the health system’s catchment area that registered ≥ 3 positive cases and ≥ 50 completed tests, as well as geographically adjacent zip codes with ≥ 2 positive cases and ≥ 50 tests, were included.

Central Line Associated Blood Stream Infection Prevention With Use Of Disinfection Caps: A Scoping Review, Marianne E. Person, Jessica Biggs, Elizabeth Ross, Margaret Harvey Phd, Aprn, Acnp-Bc, Chfn

Doctor of Nursing Practice Projects

Purpose/Background Central lines provide lifesaving uses, but they also place the patient at risk for central line associated blood stream infections (CLABSI). Catheter location, length of stay, handwashing, dressing changes, and disinfection of ports before use are all factors to prevent CLABSIs, yet sometimes these measures are not enough. Disinfecting caps are another way to decrease central line infection, however not all hospitals use this method. This scoping review aims to compare CLABSI rates with and without the use of disinfecting caps for the duration of central line use in intensive care patients.

Methods From August 2019 to September 2021, …

Study Of Glucose Supplementation On Antibiotic Efficacy Against Staphylococcus Aureus, Areej Malik, Alexandra E. Chittams-Miles, Claudia Muratori, Erin B. Purcell

College of Sciences Posters

Staphylococcus aureus (S. aureus), is a Gram-positive, facultative anaerobic, biofilm-forming bacterium. It is the leading cause of skin and soft tissue infections (SSTIs) in the United States. The public health impact of S. aureus has been increased by the emergence of Methicillin-resistant Staphylococcus aureus. It has also shown intermediate resistance to Vancomycin, which suggests that full resistance may develop. It is known that hyperglycemia (high blood sugar) from diabetes reduces immune system function. Patients with diabetes experience a greater rate of skin and soft tissue infections. This research explores the effect of increasing glucose concentration on S. …

Cellular Dynamics And Disease Outcome Of Type 3 Streptococcus Pneumoniae Clinical Isolates Differ Between Strains, Taylor Rae Plunkett White

Theses and Dissertations (ETD)

Streptococcus pneumoniae is a bacterial pathogen that continues to be a major cause of disease around the world. It is not only the number one cause of bacterial pneumonia but also the cause of about 15% of the deaths of children under 5 around the world. There is a lot of research done on this organism, but with around 100 known serotypes and each one producing a unique capsule, there is still much more to be studied. The Etiology of Pneumonia in the Community (EPIC) study conducted by the CDC observed the burden of hospitalizations caused by pneumonia while determining …

“Pandemias Políticas: The Effects Of Political And Social Instability On Infectious Disease Epidemiology In Latin America"”, Sarah H. Noonan

Senior Theses

This paper seeks to analyze the relationship between political and social unrest and conflict and infectious disease epidemiology in Latin America. An analysis of published literature regarding epidemiological, biomedical, political, and historical content was conducted to highlight potential connections between infectious disease epidemics and sociopolitical conflict in the region. Specific analyses of Smallpox, Venezuelan Equine Encephalitis, Chagas disease, Cholera, Dengue, and COVID-19 were conducted, in an effort to uncover potential causations and context of epidemics of these conditions. Results of this analysis depict a necessity for further research into public health and disease control mechanisms during times of conflict and …

The Effects Of Mosaic Law Observance On Human Health, Emily Uhlmeyer

Senior Honors Theses

For the people of ancient Israel, life was guided and regulated by adherence to the law of Moses. Dietary restrictions, purification rituals, circumcision, and Sabbath observance were each critical components of this code and were meticulously detailed in the Old Testament, specifically in the Torah. Still today, dietary laws are observed and select rituals practiced by many Jews and Seventh Day Adventists. Although health protection was never the primary purpose of the law, noticeable effects on human health have been connected to its observance. Evaluation of the effects of the Levitical law on human health can be achieved by a …

The Large And Small Of It: The Microbiome And Metagenomics, Austin Hopkins, Elaina Gollmar, Jessica Fernandez, Shawn Wolf, Austin Hilverding, Andrew M. Roecker

Pharmacy and Wellness Review

Metagenomics, the analysis of the microbial genome, permits scientists to understand the influences of external sources including diet, metabolism and antibiotics on the human microbiome. Research has revealed the possibility of a core symbiosis between humans and bacteria. The main role of the human microbiome is to aid in digestion, but identified ancillary roles include immunologic homeostasis and infection prevention. Quantifying the composition and variability of the microbiome will help lead to future treatments or preventive strategies against unhealthy change. A variety of methods may be used to define the microbiome, and 16S amplicon sequencing is primarily utilized today. Probiotics …

Knowledge And Practices On The Prevention And Management Of Diarrhea In Children Under-2 Years Among Women Dwelling In Urban Slums Of Karachi, Pakistan, Asif Khaliq, Amreen 1, Nazia Jameel, Stefanie J. Krauth

Department of Paediatrics and Child Health

Background: Diarrhea is the second leading cause of death especially among children. The age-proportionate mortality of diarrheal disease in infants under 2 years is 72%, among children under 5 years of age. Children living in urban slums are more prone to develop diarrhea. Although the disease can be prevented by many simple cost-effective interventions, i.e. proper sanitation and hygiene, appropriate feeding, and timely vaccination, poverty and lack of basic life amenities often potentiate diarrhea mortality. Gadap town is the largest town of Karachi with a deprived health system. This study aims to assess pediatric diarrhea prevalence and related knowledge-practice gaps …

Variants Associated With Bedaquiline (Bdq) Resistance Identified In Rv0678 And Efflux Pump Genes In Mycobacterium Tuberculosis Isolates From Bdq Naïve Tb Patients In Pakistan, Dania Khalid Saeed, Sadia Shakoor, Safina Abdul Razzak, Zahra Hasan, Saba Faraz Sabzwari, Zahida Azizullah, Akber Kanji, Asghar Nasir, Samreen Shafiq, Najia Karim Ghanchi, Rumina Hasan

Department of Pathology and Laboratory Medicine

Background: Mutations in the Rv0678, pepQ and atpE genes of Mycobacterium tuberculosis (MTB) have been reported to be associated with reduced antimycobacterial susceptibility to bedaquiline (BDQ). Resistance conferring mutations in treatment naïve MTB strains is likely to have implications for BDQ based new drug regimen that aim to shorten treatment duration. We therefore investigated the genetic basis of resistance to BDQ in MTB clinical isolates from BDQ naïve TB patients from Pakistan. In addition, mutations in genes associated with efflux pumps were investigated as an alternate mechanism of resistance.
Methods: Based on convenience sampling, we studied 48 MTB clinical isolates …

Methods: We conducted a literature review of peer-reviewed publications in English on the clinical and epidemiological features of respiratory PASC in cohorts of 100 or more patients with a follow-up of four weeks or more after acute infection. Included studies reported the prevalence of persistent respiratory symptoms and/or the results of follow-up pulmonary function tests.

Results: On our review included 14 studies across eight countries …

Compliance With Guidelines For Treatment Of Staphylococcus Aureus Bacteremia Is Associated With Decreased Mortality In Patients Hospitalized For Community-Acquired Pneumonia With Staphylococcus Aureus Bacteremia, Leslie Beavin, Vidyulata Salunkhe, Shashvin Singh, Ahmed Gana, Balaji Sekaran, Mahder A. Tella, Stephen P. Furmanek, Forest W. Arnold

The University of Louisville Journal of Respiratory Infections

Introduction: Staphylococcus aureus bacteremia has a minimum treatment duration of two weeks, while S. aureus community-acquired pneumonia (CAP) treatment is at least five days. Treatment failure, persistent bacteremia, and recurrence are common among patients with community-acquired S. aureus bacteremia. There is conflicting information in the current Infectious Diseases Society of America (IDSA) guidelines for the treatment of S.aureus bacteremia patients with CAP. Therefore, the appropriate treatment duration and modality for S. aureus CAP with bacteremia is unclear. The objective of this study was to compare outcomes among patients with S. aureus CAP and bacteremia treated in compliance versus non-compliance with …
