Antistaphylococcal penicillins and cefazolin remain the primary treatments for infections with methicillin-susceptible Staphylococcus aureus (MSSA). The cefazolin inoculum effect (CzIE) causes the cef...
Methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia is associated with poor outcomes. Ceftriaxone offers logistical advantages over other standard therapies, though in vitro studies have q...
Staphylococcus epidermis is one of the most frequent causes of device-associated infections due to biofilm formation. Current reports noted that subinhibitory concentrations of antibiotics induce biof...
Recently, global health concerns regarding increasing multidrug resistance have arisen. This study aimed to develop a simple, inexpensive and rapid high-performance liquid chromatography-ultraviolet (...
The optimal perioperative antimicrobial agent for preventing surgical site infection (SSI) in pancreatoduodenectomy (PD) with preoperative biliary drainage (PBD) remains unclear....
We retrospectively reviewed 288 patients who underwent PD after PBD between 2010 and 2020 at our institution. Patients were classified into two groups according to the perioperative antimicrobial agen...
The incidence of incisional SSI was significantly lower in the CTRX group than in the CEZ group (18% vs. 31%, P = 0.021), whereas the incidence of organ/space SSI in the two groups did not differ to a...
CTRX had better antimicrobial coverage than CEZ for GNR cultured from intraoperative bile samples. In addition, CTRX provides better antimicrobial prophylaxis than CEZ against superficial SSI in patie...
This study was not a clinical trial and had no registration numbers....
Antistaphylococcal penicillins (ASP) and cefazolin are first-line treatment of methicillin-susceptible Staphylococcus aureus (MSSA) bacteremia. Borderline oxacillin resistance (i.e., oxacillin MICs 1-...
