Prosthetic valve endocarditis caused by Pseudomonas aeruginosa with variable antibacterial resistance profiles: a diagnostic challenge

Infective endocarditis (IE) caused by gram-negative bacilli is rare. However, the incidence of this severe infection is rising because of the increasing number of persons at risk, such as patients with immunos...

This case describes a brachial artery mycotic aneurysm (BAMA) secondary to infective endocarditis caused by Enterococcus faecalis. BAMAs are rare and potentially limb or life threatening. A literature review revealed 61 cases since 1950, primarily caused by intravenous drug use, with Staphylococcus aureus being the most common causative bacteria.

In conclusion, we show here that sEVs are responsible for mediating paracrine senescence and speculate that they could be involved in inducing bystander senescence during therapy-induced senescence or aging. In fact, when compared to soluble factors, sEVs have different biophysical and biochemical properties as they have a longer lifespan than do soluble factors and they are more resistant to protease degradation. The idea that blocking sEV secretion could be a potential therapeutic approach to alleviate senescence "spreading" during chemotherapy-induced senescence or in aging tissues presents itself as a very at...

Conclusions: This original model of infective endocarditis recapitulates the neurologic lesion spectrum observed in humans and suggests synergistic mechanisms involved, including thromboembolism and cerebral vasculitis, promoted by a systemic bacteremia-mediated inflammation.

We present a case of E. rhusiopathiae mitral valve endocarditis in a farmer with psoriasis presented with acute intractable heart failure requiring valve replacement surgery. E. rhusiopathiae was identified by 16S rRNA-based gene sequencing from culture-negative, surgically excised mitral valve leaflets.

To prevent infective endocarditis (IE), with the exception of the United Kingdom, antibiotic prophylaxis (AP) is recommended in patients with predisposing cardiac conditions (PCCs) worldwide. To conclude on the relevance of this strategy, how the current guidelines are applied is a crucial point to investigate. The first aim of this study was to assess cardiologists' implementation of the current guidelines. The secondary objective was to identify specific areas where the training and knowledge of French cardiologists could be improved.

ConclusionsIn non-elderly adults undergoing surgery for aortic valve endocarditis, mid-term survival is suboptimal. Although non-IVDU patients with native valve endocarditis have better mid-term outcomes, yet survival remains lower than a matched population of elective AVR in non-elderly patient.

Abstract BACKGROUND: Bacterial infective endocarditis (IE) is rarely suspected in patients with a low C-reactive protein (CRP) concentration. AIMS: To address the incidence, characteristics and outcome of left-sided valvular IE with low CRP concentration. METHODS: This was a retrospective analysis of cases of IE discharged from our institution between January 2009 and May 2017. The 10% lowest CRP concentration (
