Effect of Contact Precautions on Staphylococcus aureus and Clinical Outcomes of Colonized Patients in the Neonatal Intensive Care Unit
Background: Staphylococcus aureus is a common pathogen in neonatal intensive care units (NICUs), yet little is known about the effect of contact precautions and clinical outcomes of colonized patients. Methods: Retrospective cohort study of all neonates from August 2014 to November 2018 colonized with either methicillin-resistant S. aureus (MRSA) or methicillin-susceptible S. aureus (MSSA) and select noncolonized patients at two neonatal intensive care units at the University of California, Los Angeles. Outcomes during two time periods (during and after the use of contact precautions) were assessed. Results: A total of 234 patients were included in the study: 83 colonized and 151 noncolonized patients. There was a fourfold higher incidence of MSSA colonization versus MRSA (P
CONCLUSION: There is a high prevalence of MRSA causing abscesses in the Hispanic population evaluated in an ED in Puerto Rico. Systemic antibiotic use for the treatment of skin abscesses after incision and drainage remains high despite published guidelines arguing against their widespread use. Clindamycin resistance in our patient population appears to be more frequent than previously reported. PMID: 33031694 [PubMed - as supplied by publisher]
The difference in sequential organ failure assessment (SOFA) scores from the baseline to sepsis is a known predictor of sepsis-3 outcome, but the prognostic value of drug-resistant organisms for mortality is unexplained. We employed sepsis stewardship and herein report an observational study. Study subjects were patients admitted to the Departments of Surgery/Chest Surgery from 2011 through 2018 with a diagnosis of sepsis and a SOFA score of 2 or more. Our sepsis stewardship methods included antimicrobial and diagnostic stewardship and infection control. We determined the primary endpoint as in-hospital death and the secon...
Authors: Saxena D, Kaul G, Dasgupta A, Chopra S Abstract Acute bacterial skin and skin structure infections (ABSSSIs) are one of the most common types of infections due to methicillin-resistant Staphylococcus aureus (MRSA). The standard of care for ABSSSI includes glycopeptides such as vancomycin, teicoplanin, oxazolidinones and fluoroquinolones, which are potent broad-spectrum antibacterial agents. Unfortunately, due to indiscriminate utilization, resistance to these agents is rising and identification of novel agents is an urgent unmet medical need. In this context, levonadifloxacin (WCK-771) is a novel, hydrate ...
Biofilms pose a relevant factor for wound healing impairment in chronic wounds. With 78% of all chronic wounds being affected by biofilms, research in this area is of high priority, especially since data for evidence-based selection of appropriate antimicrobials and antiseptics is scarce. Therefore, the objective of this study was to evaluate the anti-biofilm efficacy of commercially available hypochlorous wound irrigation solutions compared to established antimicrobials. Using an innovative complex in-vitro human plasma biofilm model (hpBIOM), quantitative reduction of Pseudomonas aeruginosa, Staphylococcus aureus, and Me...
Conclusions: Our results provide novel evidence that the product of P. intermedia exerts a pathogenic effect on MRSA pneumonia, in particular with a strain exhibiting strong proliferation in the lower airway tract. Moreover, our results indicate that P. intermedia affects MRSA toxin expression via quorum sensing in a strain-dependent fashion, which might be important for understanding the pathogenesis of severe MRSA pneumonia.
This study characterized the epidemiological status, antibiotic resistance patterns, and current prevalent phenotypes of healthcare-associated MRSA. This knowledge can aid clinicians in improving the antimicrobial stewardship program by adapting appropriate guidelines for the proper use of MRSA antibacterial agents.

Conclusion A 5-day universal decolonization protocol before LVAD implantation was effective in reducing total infections as well as MRSA-specific infections.

Abstract Given that it unlikely that randomized clinical trials will yield the answers in treating the most challenging bacteremic infections caused by methicillin-resistant Staphylococcus aureus, clinicians, microbiologists, and pharmacists will have to cooperate to discover novel ways in selecting successful individualized antimicrobial therapy for these patients. An example of such a strategy was demonstrated in the identification and utilization of imipenem/cilistatin plus fosfomycin to treat a particularly recalcitrant MRSA bacteremia and spinal abscess.

Conclusions: Our studies of nanosystem provide a promising synergic therapeutic strategy for postcataract endophthalmitis treatment with favorable prognosis and promise in clinical translations.
