Wounds are colonized frequently by heterogeneous microflora. Pseudomonas aeruginosa (PA) and Staphylococcus aureus (SA) are two of the most isolated bacterial species from wounds, and both typically form highly organized biofilms. Nitric oxide (NO) is a short-lived, diatomic, lipophilic gas with antimicrobial activity. Recently, NO and its derivatives have been shown to exhibit broad-spectrum antimicrobial activity against bacteria, viruses, and parasites. ⋯ These studies demonstrate that NO-releasing topical formulations effectively reduce the MRSA burden in established biofilms composed of multiple microorganisms. Minimal efficacy against PA was observed. It has been demonstrated that MRSA bioburden is significantly reduced when inoculated together with P. aeruginosa. A better understanding of mechanisms of host-bacteria interactions, in single or mixed species biofilms, may lead to the development of novel therapeutic approaches. Overall, NO offers a promising alternative treatment against MRSA in polymicrobial infections.

Multicenter Study Comparative Study
Insulin Efsitora versus Degludec in Type 2 Diabetes without Previous Insulin Treatment.
Insulin efsitora alfa (efsitora) is a new basal insulin designed for once-weekly administration. Data on safety and efficacy have been limited to small, phase 1 or phase 2 trials. ⋯ In adults with type 2 diabetes who had not previously received insulin, once-weekly efsitora was noninferior to once-daily degludec in reducing glycated hemoglobin levels.

Randomized Controlled Trial Multicenter Study Comparative Study
PCI in Patients Undergoing Transcatheter Aortic-Valve Implantation.
The benefit of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease and severe aortic stenosis who are undergoing transcatheter aortic-valve implantation (TAVI) remains unclear. ⋯ Among patients with coronary artery disease who were undergoing TAVI, PCI was associated with a lower risk of a composite of death from any cause, myocardial infarction, or urgent revascularization at a median follow-up of 2 years than conservative treatment.

Transthyretin amyloidosis with cardiomyopathy (ATTR-CM) is a progressive, often fatal disease. Nexiguran ziclumeran (nex-z) is an investigational therapy based on CRISPR-Cas9 (clustered regularly interspaced short palindromic repeats and associated Cas9 endonuclease) targeting the gene encoding transthyretin (TTR). ⋯ In this phase 1 study involving patients with ATTR-CM, treatment with a single dose of nex-z was associated with transient infusion-related reactions and consistent, rapid, and durable reductions in serum TTR levels. (Funded by Intellia Therapeutics and Regeneron Pharmaceuticals; ClinicalTrials.gov number, NCT04601051.).

Health systems experience difficult trade-offs when paying for new drugs. In England, funding recommendations by the National Institute for Health and Care Excellence (NICE) for new drugs might generate health gains, but inevitably result in forgone health as the funds cannot be used for alternative treatments and services. We aimed to evaluate the population-health impact of NICE recommendations for new drugs during 2000-20. ⋯ The Commonwealth Fund.
