Does MRSA Nares Colonization Predict Non-Respiratory MRSA Infections?
Nares screening for methicillin-resistant Staphylococcus aureus (MRSA) has a high negative predictive value to rule out MRSA infections at various sites.

Cefazolin and Ertapenem as Salvage Therapy in Methicillin-Susceptible Staphylococcus aureus Bacteremia
Cefazolin (CZ) and ertapenem combination therapy was successfully used to salvage 11 cases of persistent methicillin-susceptible Staphylococcus aureus bacteremia. Modest in vitro synergy between CZ and ertapenem was demonstrated on testing of six clinical isolates, but in vivo activity appeared more potent in an animal model than as predicted by in vitro activity.

Preventing Readmissions and Optimizing Outcomes for Staphylococcus aureus Bacteremia: Still a Long Journey Ahead
Using a population-based database, investigators found that the rate of readmission within 30 days following hospitalization for S. aureus bacteremia was high (22%) and resulted in high cost to the healthcare system.

Combination Therapy With Daptomycin Plus Beta-Lactam Antibiotics in MSSA Bacteremia
In a retrospective cohort study of 350 patients, the combination of a beta-lactam antibiotic plus daptomycin was not superior to beta-lactam monotherapy in patients with bacteremia due to methicillin-susceptible Staphylococcus aureus.

Trimethoprim Sulfamethoxazole Plus Clindamycin for Treatment of Staphylococcus aureus Endocarditis
A before-and-after intervention study compared 170 patients treated with either oxacillin IV or vancomycin IV for six weeks (plus gentamicin IV given during the first five days) to 171 patients who were treated with TMP/SMZ IV plus clindamycin IV for the first week followed by TMP/SMZ PO (without clindamycin) to complete a six-week course. Mortality and hospital length of stay were significantly less in the TMP/SMZ-treated patients.

Vancomycin for MRSA Pneumonia Following Influenza in Children
Coinfection with methicillin-resistant Staphylococcus aureus (MRSA) in children with influenza is associated with high fatality. Data support the addition of a second anti-MRSA antibiotic to vancomycin in severely ill children.

Staphylococcus aureus Bloodstream Infections in the United States
Although the rate of hospital-onset MRSA bacteremia has decreased since 2012, the rate of decrease has slowed. The National Action Plan goal of a 50% reduction by 2012 compared to 2015 seems out of reach.

Staphylococcus aureus on the Playground and in the Gym — Is It Inescapable?
Staphylococcus aureus, including methicillin-resistant S. aureus, is a frequent surface environmental contaminant on both children’s playgrounds and in adult fitness centers.

Does Adding Rifampin to Standard Therapy Improve Outcomes in Patients With Staphylococcus aureus Bacteremia?
The addition of rifampin to standard therapy failed to provide significant benefit to patients with bacteremia due to Staphylococcus aureus.

MRSA Infections May Lead to Prolonged Impairment of Lymphatic Vessel Function
In the first study to investigate the potential interactions between bacterial infections and lymphatic function, researchers found that methicillin-resistant Staphylococcus aureus toxins killed muscle cells critical to the pumping of lymph fluid and led to prolonged lymphatic dysfunction months after the bacteria had been cleared.
