Abstract

The microorganisms that inhabit hospitals may influence patient recovery and outcome, although the complexity and diversity of these bacterial communities can confound our ability to focus on potential pathogens in isolation. To develop a community-level understanding of how microorganisms colonize and move through the hospital environment, we characterized the bacterial dynamics among hospital surfaces, patients, and staff over the course of 1 year as a new hospital became operational. The bacteria in patient rooms, particularly on bedrails, consistently resembled the skin microbiota of the patient occupying the room. Bacterial communities on patients and room surfaces became increasingly similar over the course of a patient's stay. Temporal correlations in community structure demonstrated that patients initially acquired room-associated taxa that predated their stay but that their own microbial signatures began to influence the room community structure over time. The α- and β-diversity of patient skin samples were only weakly or nonsignificantly associated with clinical factors such as chemotherapy, antibiotic usage, and surgical recovery, and no factor except for ambulatory status affected microbial similarity between the microbiotas of a patient and their room. Metagenomic analyses revealed that genes conferring antimicrobial resistance were consistently more abundant on room surfaces than on the skin of the patients inhabiting those rooms. In addition, persistent unique genotypes of Staphylococcus and Propionibacterium were identified. Dynamic Bayesian network analysis suggested that hospital staff were more likely to be a source of bacteria on the skin of patients than the reverse but that there were no universal patterns of transmission across patient rooms. more...

Abstract

We present the first case of native aortic valve endocarditis caused by Scopulariopsis. Intraoperative images and videos from valve replacement surgery illustrate the severity of fungal endocarditis. This case demonstrates the aggressive presentation of left-sided fungal endocarditis, highlights challenges with treating highly resistant fungi, and considers the potential utility of olorofim.

Abstract

This report details the outcome of the 1st Hospital Microbiome Project workshop held on June 7th-8th, 2012 at the University of Chicago, USA. The workshop was arranged to determine the most appropriate sampling strategy and approach to building science measurement to characterize the development of a microbial community within a new hospital pavilion being built at the University of Chicago Medical Center. The workshop made several recommendations and led to the development of a full proposal to the Alfred P. Sloan Foundation as well as to the creation of the Hospital Microbiome Consortium. more...

Abstract

Author(s): Luke R. Thompson [1, 2, 3]; Jon G. Sanders [1]; Daniel McDonald [1]; Amnon Amir [1]; Joshua Ladau [4]; Kenneth J. Locey [5]; Robert J. Prill [6]; Anupriya Tripathi [...], Our growing awareness of the microbial worlds importance and diversity contrasts starkly with our limited understanding of its fundamental structure. Despite recent advances in DNA sequencing, a lack of standardized protocols and common analytical frameworks impedes comparisons among studies, hindering the development of global inferences about microbial life on Earth. Here we present a meta-analysis of microbial community samples collected by hundreds of researchers for the Earth Microbiome Project. Coordinated protocols and new analytical methods, particularly the use of exact sequences instead of clustered operational taxonomic units, enable bacterial and archaeal ribosomal RNA gene sequences to be followed across multiple studies and allow us to explore patterns of diversity at an unprecedented scale. The result is both a reference database giving global context to DNA sequence data and a framework for incorporating data from future studies, fostering increasingly complete characterization of Earths microbial diversity. more...

27. Clostridioides difficilecolonization and the frequency of subsequent treatment for C. difficileinfection in critically ill patients

Author

MacKenzie, Erica L., Murillo, Cynthia, Bartlett, Allison H., Marrs, Rachel, Landon, Emily M., and Ridgway, Jessica P.

Abstract

AbstractObjective:To determine risk factors for Clostridioides difficilecolonization and C. difficileinfection (CDI) among patients admitted to the intensive care unit (ICU).Design:Retrospective observational cohort study.Setting:Tertiary-care facility.Patients:All adult patients admitted to an ICU from July 1, 2015, to November 6, 2019, who were tested for C. difficilecolonization. Patients with CDI were excluded.Methods:Information was collected on patient demographics, comorbidities, laboratory results, and prescriptions. We defined C. difficilecolonization as a positive nucleic acid amplification test for C. difficileup to 48 hours before or 24 hours after intensive care unit (ICU) admission without evidence of active infection. We defined active infection as the receipt of an antibiotic whose only indication is the treatment of CDI. The primary outcome measure was the development of CDI up to 30 days after ICU admission. Logistic regression was used to model associations between clinical variables and the development of CDI.Results:The overall C. difficilecolonization rate was 4% and the overall CDI rate was 2%. Risk factors for the development of CDI included C. difficilecolonization (aOR, 13.3; 95% CI, 8.3–21.3; P< .0001), increased ICU length of stay (aOR, 1.04; 95% CI, 1.03–1.05; P< .0001), and a history of inflammatory bowel disease (aOR, 3.8; 95% CI, 1.3–11.1; P= .02). Receipt of any antibiotic during the ICU stay was associated with a borderline increased odds of CDI (aOR, 1.9; 95% CI, 1.0–3.4; P= .05).Conclusion:C. difficilecolonization is associated with the development of CDI among ICU patients. more...
