Two prominent studies have been used by policy makers to prevent the enactment of standards of care regarding active surveillance of patients with methicillin-resistant Staphylococcus aureus in hospital settings. In this brief review and perspective of those studies, we contend that both studies have serious limitations (i.e., the intervention group was not given optimal intervention) that may not have been scrutinized by many policy makers, health officials, and other researchers. These studies seem to have had a disproportionate impact on health-care policy despite their limitations. Furthermore, health-care policy and treatment standards need to reflect the preponderance of evidence with appropriate weight given to research studies based on their strengths and limitations. Only then can treatment standards that are effective against methicillin-resistant Staphylococcus aureus be adopted or refuted.

Introduction: Nanobubble ozone stored in hyaluronic acid-decorated liposomes (patent application PCT/TR2022/050177) was used, and the Minimum Inhibitory Concentration (MIC) was found to be 1562 ppm. (patient isolate), (patient isolate), (MRSA) (ATCC12493), and (ATCC25922) bacteria, which are hospital-acquired and healthcare-associated infections, were used. A time-dependent efficacy study was conducted at 1600 ppm.

The Hepatorenal Syndrome-Acute Kidney Injury (HRS-AKI) patients infected with methicillin-resistant (MRSA) urgently require safe and effective treatment options due to their compromised hepatic and renal functions, as well as thrombocytopenia resulting from hypersplenism. In our case, an HRS-AKI patient who underwent continuous renal replacement therapy for fluid overload developed fever with chills. His blood tests indicated elevated C-reactive protein and neutrophils, low platelet count, and bilateral lung infiltrates.

Marine-derived actinobacteria isolated from sponge and soft coral were screened for antibacterial activity against acne-related bacteria, specifically ATCC 14990, methicillin-resistant ATCC BAA44, and ATCC 6919. Cytotoxicity assays were performed on human dermal fibroblast (HDFa) and keratinocyte (HaCaT) cell lines to assess the safety profile of the extracts. Chemical characterization was conducted using high-performance liquid chromatography coupled with tandem mass spectrometry (HPLC-MS/MS).

Background: Methicillin-resistant Staphylococcus aureus (MRSA) is a formidable public scourge causing worldwide mild to severe life-threatening infections. The ability of this strain to swiftly spread, evolve, and acquire resistance genes and virulence factors such as pvl genes has further rendered this strain difficult to treat. Of concern, is a recently recognized ability to resist antiseptic/disinfectant agents used as an essential part of treatment and infection control practices.

Multidrug-resistant (MDR) bacterial infections pose a severe threat to global public health and present significant challenges in the treatment of bacterial keratitis. The escalation of antimicrobial resistance (AMR) underscores the urgent need for alternative therapeutic strategies. In this study, we report the homogeneous synthesis of quaternized ultra-highly deacetylated chitosan (QUDCS) using a sequential acid-base combination approach.
