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.

Stakeholder engagement in a comparative effectiveness/implementation study to prevent Staphylococcus aureus infection recurrence: CA-MRSA Project (CAMP2).
The purpose of this study was to determine whether the presence and participation of a stakeholder committee would positively impact the effectiveness of the design and execution of a home-based Methicillin-resistant Staphylococcus aureus and methicillin-sensitive Staphylococcus aureus infection prevention intervention. The trial utilized community health workers to implement infection prevention protocols in participant’s homes, including home visits, sampling household surfaces at baseline and then three months, and obtaining surveillance cultures from index patients and household members. The study assembled and convened The Clinician and Patient Stakeholder Advisory Committee (CPSAC), comprised of New York-based federally qualified health centers (FQHCs) and community health emergency departments, laboratory and clinical researchers, clinicians, and patient stakeholders. The CPSAC was tasked with trial oversight and shared decision-making and troubleshooting, and convened both in person and remotely. The researchers concluded that the inclusion and engagement of the CPSAC during the trial design and implementation was highly effective in addressing and resolving challenges in both participant recruitment and home visits.
