Bayesian modeling of the impact of antibiotic resistance on the efficiency of MRSA decolonization.
The authors analyzed how the persistence of methicillin-resistant Staphylococcus aureus (MRSA) colonization correlates with the genomic presence of antibiotic resistance genes. Using a Bayesian mixed effects survival model, they found that genetic determinants of high-level resistance to mupirocin was strongly associated with failure of the decolonization protocol, but they did not find a similar effect with genetic resistance to chlorhexidine or other antibiotics. They concluded that these results highlight the need to consider the properties of the colonizing MRSA strain when deciding which treatments to include in the decolonization protocol.

Going back in time: Increasing penicillin susceptibility among methicillin-susceptible staphylococcus aureus osteoarticular infections in children.
Researchers investigated the prevalence of penicillin susceptibility (PSSA) among pediatric methicillin susceptible S. aureus (MSSA) acute hematogenous osteoarticular infection (OAI) isolates; the isolates were obtained through surveillance studies at Texas Children's and St. Louis Children's Hospitals. Overall, PSSA isolates were found to be associated with a similar clinical presentation as penicillin-resistant isolates. The researchers concluded that potential for use of penicillin treatment in PSSA OAI merits further study.

Reduced ceftaroline susceptibility among invasive mrsa infections in children: a clinical and genomic investigation.
The purpose of this study was to assess the frequency of reduced susceptibility (RS) to ceftaroline among pediatric methicillin-resistant Staphylococcus aureus (MRSA) infections. The researchers evaluated MRSA isolates at a tertiary children's hospital for ceftaroline RS. Ceftaroline RS occurred only among health care associated infections in 2.9% of isolates, and were more often clindamycin-resistant.

De-escalation of empiric antibiotics following negative cultures in hospitalized patients with pneumonia: rates and outcomes.
This study assessed antibiotic de-escalation practices across hospitals and their associations with outcomes in hospitalized patients diagnosed with pneumonia with negative cultures. The authors included 14,170 adults admitted with pneumonia in 2010-2015 to 164 US hospitals if they had negative blood and/or respiratory cultures and received both anti-MRSA and antipseudomonal agents other than quinolones. If empiric drugs were stopped on day 4 while continuing another antibiotic it was defined at de-escalation. Patients were propensity adjusted for de-escalation and compared on in-hospital 14-day mortality, late deterioration with ICU transfer, length-of-stay (LOS) and costs. Thirteen percent (1924 patients) had both initial empiric drugs stopped by hospital day 4. De-escalation rates at hospitals ranged from 2-35% and the established rate quartiles were not significantly associated with outcomes. Even at hospitals in the top quartile of de-escalation, the de-escalation rates were lower than 50%.

Antibiotic regimens and associated outcomes in children hospitalized with staphylococcal scalded skin syndrome.
Controversy exists regarding the optimal antibiotic regimen for use in hospitalized children with staphylococcal scalded skin syndrome (SSSS). Various regimens may confer toxin suppression and/or additional coverage for methicillin-susceptible Staphylococcus aureus (MSSA) or methicillin-resistant S aureus (MRSA). The purpose of this study was to describe antibiotic regimens in hospitalized children with SSSS and examine the association between antistaphylococcal antibiotic regimens and patient outcomes.

Current infection prevention and antibiotic stewardship program practices: a survey of the Society for Healthcare Epidemiology of America (SHEA) Research Network (SRN).
This survey compares results with a similar 2013 survey that characterizes contemporary infection prevention and antibiotic stewardship program practices across 64 healthcare facilities. There was decreased frequency of active surveillance for MRSA, frequent active surveillance for carbapenem-resistant Enterobacteriaceae, and increased support for antibiotic stewardship programs.

Increasing clindamycin and trimethoprim-sulfamethoxazole resistance in pediatric Staphylococcus aureus Infections.
This retrospective observational study looked at pediatric clinical cultures between 2005 and 2017 that grew Staphylococcus aureus culture and their trends in antibiotic resistance. Methicillin resistance declined but clindamycin and trimethoprim-sulfamethoxazole resistance increased significantly.

Prevalence of staphylococcus aureus and use of antistaphylococcal therapy in children hospitalized with pneumonia.
In a studied group of children hospitalized with community-acquired pneumonia, staphylococcal pneumonia was rare but associated with adverse in-hospital outcomes. Despite this low prevalence, use of antistaphylococcal antibiotics was common. The authors recommended efforts to minimize overuse of antistaphylococcal antibiotics while also ensuring adequate treatment for pathogen-specific diseases.

Comparison of empiric antibiotics for acute osteomyelitis in children.
Broad-spectrum antibiotics are commonly used for the empiric treatment of acute hematogenous osteomyelitis and often target methicillin-resistant Staphylococcus aureus (MRSA) with medication-associated risk and unknown treatment benefit. In this study, the investigators aimed to compare clinical outcomes among patients with osteomyelitis who did and did not receive initial antibiotics used to target MRSA. The investigators found that, early antibiotic treatment used to target MRSA was associated with a higher rate of repeat MRI.

Resistance to zinc and cadmium in Staphylococcus aureus of human and animal origin.
The investigators determined the prevalence of zinc and cadmium resistance in S. aureus isolated in the United States. They found that resistance to zinc and cadmium was observed to be associated with MRSA, suggesting that prolonged exposure to zinc in livestock feeds and fertilizers could propagate resistance to the metal ion, hindering the use of zinc-based topical agents in treating S. aureus infections.
