Based on the fact that beta-lactam antibiotics demonstrate time-dependent killing, different dosing strategies have been implemented to increase the time that free (f) (unbound) antibiotic concentrations remain above the Minimal Inhibitory Concentration (MIC), including prolonged and continuous infusion. Multiple studies have been performed that compared continuous with traditional intermittent infusion to improve outcomes in patients with severe sepsis and/or septic shock. These studies have yielded inconsistent results for patients as measured by clinical response to treatment and mortality due to heterogeneity of included patients, pathogens, dosing strategies and the absence of Therapeutic Drug Monitoring (TDM).

Background: Multidrug-resistant Klebsiella pneumoniae (MDR-KP) infections pose a significant global healthcare challenge, particularly due to the high mortality risk associated with septic shock. This study aimed to develop and validate a machine learning-based model to predict the risk of MDR-KP-associated septic shock, enabling early risk stratification and targeted interventions.
Methods: A retrospective analysis was conducted on 1,385 patients with MDR-KP infections admitted between January 2019 and June 2024.
Recurrent Bacteremia in the Setting of Pseudomonas Endocarditis of the Tricuspid Valve and Indwelling Medical Devices.

This case report presents a complex and challenging scenario of recurrent () bacteremia and tricuspid valve endocarditis in a 77-year-old male patient with multiple comorbidities and indwelling medical devices. The patient's medical history was significant for T4 paraplegia, neurogenic bladder requiring a chronic indwelling suprapubic catheter, heart block status post-permanent pacemaker placement, type 2 diabetes mellitus, chronic kidney disease, and chronic sacral wounds. The case highlights the difficulties in managing antibiotic-resistant infections, particularly in patients with implantable devices and chronic wounds.

Background: Open pelvic fractures are rare but represent a serious clinical problem with high mortality rates. Acute mortality is often associated with hemorrhage, whereas delayed mortality is most often associated with sepsis and multiple organ failure. We report a case of Wang's classification of type II open pelvic ring fracture with hemorrhagic shock and septic shock from gas gangrene.
