Antibiotic Resistance to Third Generation Cephalosporins Due to CTX-M-Type Extended-Spectrum β-Lactamases in Clinical Isolates of Escherichia coli [PDF]

Iranian Journal of Public Health, 2009
Background: Organisms producing CTX-M-β-lactamase are emerging around the world as a source of resistance to oxyiminocephalosporins such as cefotaxime. However, the laboratory detection of these strains is not well defined.

Left ventricular diastolic dysfunction worsens prognosis in patients with heart failure due to dilated cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1183-1193, April 2025.
Abstract Aims The prognostic significance of left ventricular (LV) diastolic dysfunction (LVDD) severity in patients with dilated cardiomyopathy (DCM) remains uncertain. This study aimed to evaluate the association of LVDD severity and elevated left atrial pressure (eLAP) with patient outcomes in stable, non‐acutely decompensated patients with DCM ...

Long‐lasting remodeling of astrocytes in an Scna1+/− mouse model of Dravet syndrome

Epilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a prototypical developmental and epileptic encephalopathy caused by mutations in the SCN1A gene, leading to loss of function of the voltage‐gated sodium channel Naᵥ1.1. The latter causes early onset drug‐resistant seizures and enduring cognitive and behavioral deficits.

Divergence of affinities, serotypes and virulence factor between CTX-M Escherichia coli and non-CTX-M producers

Poultry Science, 2018
This study was undertaken to discern the differences of the multi-locus sequence typing (MLST), O serogroups, and virulence factors among 34 CTX-M-1 Escherichia coli, 49 CTX-M-9 strains and 23 non-CTX-M isolates from chickens in Henan province, China.

Neonatal seizures and GABAergic drugs: Scylla and Charybdis?

Epilepsia Open, EarlyView.
Abstract Neonates have a high incidence of seizures that are frequently difficult to control with conventional first‐line anti‐seizure medications, which are gamma‐aminobutyric acid (GABA) agonists. The reasons for this clinical problem are multifold but are likely related to the unique physiology of the immature nervous system. Specifically, the early

Genomic Diversity and Virulence Potential of High-Priority Critically Important Antimicrobial-Resistant Escherichia coli from Pork and Chicken Retail Meat

Pathogens
The occurrence of Escherichia coli resistant to high-priority critically important antimicrobials (HPCIA) in the food chain is a growing concern for food safety and public health. This study aimed to evaluate whether HPCIA-resistant E. coli isolated from
