Corynebacterium kroppenstedtii is an immobile, non-sporulated, glucose-fermenting and lipophilic gram-positive rod of the skin microbiota. In recent years, numerous isolates of this species have been reported mainly in breast infections, such as abscesses and granulomatous mastitis. We present here four cases of C. kroppenstedtii infections isolated from breast aspiration samples in women. C. kroppenstedtii was identified by conventional methodology and mass spectrometry (MALDI-TOF MS). Using the epsilometric method, these isolates showed susceptibility to penicillin, ceftriaxone, minocycline, ciprofloxacin, and vancomycin, and variable susceptibility to clindamycin and trimethoprim sulfamethoxazole. Due to the association of C. kroppenstedtii with mammary infections, the identification at the species level of those corynebacteria isolated from this location is highly advisable in order to reach the final diagnosis and to test the antimicrobial susceptibility in order to apply the appropriate antibiotic treatment.

The severe impact of COVID-19 on global health and economies highlights the critical need for innovative treatments. Recently, lapatinib, a drug initially used for breast cancer, has been identified as a potential inhibitor of the main protease (Mpro) of SARS-CoV-2, meriting further investigation. Utilizing rational design strategies and guided by MD simulations, we developed novel aminoquinazoline analogs based on fragmented lapatinib's structure.

Regulation of pattern recognition receptor signaling by palmitoylation.

Pattern recognition receptors (PRRs), consisting of Toll-like receptors, RIG-I-like receptors, cytosolic DNA sensors, and NOD-like receptors, sense exogenous pathogenic molecules and endogenous damage signals to maintain physiological homeostasis. Upon activation, PRRs stimulate the sensitization of nuclear factor κB, mitogen-activated protein kinase, TANK-binding kinase 1-interferon (IFN) regulatory factor, and inflammasome signaling pathways to produce inflammatory factors and IFNs to activate Janus kinase/signal transducer and activator of transcription signaling pathways, resulting in anti-infection, antitumor, and other specific immune responses. Palmitoylation is a crucial type of post-translational modification that reversibly alters the localization, stability, and biological activity of target molecules.

Introduction: Breast surgeries are classified as clean procedures associated with a lower risk of post-operative infections; however, the reported infection rates post-breast surgeries are still significantly high. Surgical site infections (SSIs) are indeed one of the most common and serious complications following breast surgery.

Methodology: A retrospective study assessed the rate of SSIs post-breast reconstructive surgery after the implementation of the infection control protocol at James Cook University Hospital and Friarage Hospital from December 2022 to June 2024.
