Novel PiuC, PirA, and PiuA mutations leading to cefiderocol resistance progression in IMP-16- and KPC-2-producing from a leukemic patient.

Unlabelled: is an opportunistic pathogen capable of causing severe infections in immunocompromised individuals, who often require prolonged antibiotic therapy. The emergence of carbapenemase-producing has further complicated the management of nosocomial infections, limiting therapeutic options. Cefiderocol has recently emerged as a promising antipseudomonal agent, using the bacterial iron transport system to gain entry into the cell; however, there have been reports of resistant to cefiderocol.

Cyclic Peptide MV6, an Aminoglycoside Efficacy Enhancer Against .

: is a globally emerging pathogen with widespread antimicrobial resistance driven by multiple mechanisms, such as altered expression of efflux pumps like AdeABC, placing it as a priority for research. Driven by the lack of new treatments, alternative approaches are being explored to combat its infections, among which efficacy-enhancing adjuvants can be found. This study presents and characterizes MV6, a synthetic cyclic peptide that boosts aminoglycoside efficacy.

Diagnostic value of hemoglobin concentration in identifying Meckel's diverticulum in pediatric lower gastrointestinal bleeding.

Purpose: To assess the diagnostic performance of hemoglobin concentration for Meckel's diverticulum (MD) and evaluate if hemoglobin levels could be useful in the surgical decision-making process of children with lower gastrointestinal bleeding (LGIB).

Methods: Retrospective cohort study of children with LGIB attending the emergency department between 2011 and 2021. Episodes of LGIB were divided into two groups: MeckD (MD diagnosed by surgery) and non-MeckD.

potentiation of tetracyclines in by RW01, a new cyclic peptide.

The pipeline for new drugs against multidrug-resistant remains limited, highlighting the urgent need for innovative treatments. New strategies, such as membrane-targeting molecules acting as adjuvants, aim to enhance antibiotic effectiveness and combat resistance. RW01, a cyclic peptide with low antimicrobial activity, was selected as an adjuvant to enhance drug efficacy through membrane permeabilization.

Sodium valproate reverses aortic hypercontractility in acute myocardial infarction in rabbits.

Sympathetic nervous system (SNS), endothelin 1 (ET-1) and angiotensin II (Ang II) are involved in the pathophysiology of acute myocardial infarction (AMI). Valproic acid (VPA) is under study for the treatment against AMI due to its beneficial cardiac effects. However, the vascular effects of VPA on the activation of the SNS, ET-1 and Ang II after AMI are not fully studied.
