In Vitro Activity of Ampicillin Plus Ceftriaxone Against Non- and Non- Enterococcal Isolates With/Without VanC Phenotype: Clinical Implications for Infective Endocarditis.

(1) Background: Alternative antibiotics are needed to treat infective endocarditis (IE) caused by non-/non- enterococci; we aimed to assess the in vitro activity of ampicillin plus ceftriaxone (AMP + CTR) against these enterococci and to describe its clinical efficacy in IE cases. (2) Methods: Time-kill curves with standard (ISI) and high (IHI) inocula were performed to test isolates [3 (ECAS) and 1 (EGALL)] and non- isolates [1 (EDUR), 1 (EHIR) and 1 (ERAF)]. The narrative literature review of IE cases treated with AMP + CTR was analyzed alongside three study cases.

Gel nail polish does not have a negative impact on the nail bacterial burden nor on the quality of hand hygiene with an alcohol-based hand rub.

Background: We evaluated the microbial burden on gel polished nails (GPN), standard polished nails (SPN) and unpolished nails (UPN) before and after an alcohol-based hand rub (HHAB).

Methods: Three GPN, two SPN and five UPN in both hands were analyzed in 46 health-care workers volunteers. Nail length was maintained ≤2mm during the study.

The three-noes right-sided infective endocarditis: An unrecognized type of right-sided endocarditis.

The "3 noes right-sided infective endocarditis" (3no-RSIE: no left-sided, no drug users, no cardiac devices) was first described more than a decade ago. We describe the largest series to date to characterize its clinical, microbiological, echocardiographic and prognostic profile. Eight tertiary centers with surgical facilities participated in the study.

The hidden side of infective endocarditis: Diagnostic and management of 500 consecutive cases in noncardiac surgery centers (2009-2018).

Background: We aimed to describe infective endocarditis cases from noncardiac surgery centers, as current knowledge on infective endocarditis is derived mostly from cardiac surgery hospitals.

Methods: An observational retrospective study (2009-2018) was conducted in 9 noncardiac surgery hospitals in Central Catalonia. All adult patients diagnosed with definitive infective endocarditis were included.

Does Quality of Life in Survivors of Surgery for Acute Left-Sided Infective Endocarditis Differ from Non-Endocarditis Patients?

Surgery for left-sided infective endocarditis (IE) has been demonstrated to improve patients' survival rates but information about quality of life (QoL) after surgery is scarce. The aim of this study was to assess the postoperative outcomes and QoL after surgery for IE patients compared to patients undergoing cardiac surgery for non-IE indications. Adult patients with definite acute left-sided IE were matched 1:1 to patients who underwent cardiac surgery for non-endocarditic purposes from 2014 to 2019.

Epidemiological Changes and Improvement in Outcomes of Infective Endocarditis in Europe in the Twenty-First Century: An International Collaboration on Endocarditis (ICE) Prospective Cohort Study (2000-2012).

Introduction: Infective endocarditis (IE) has undergone important changes in its epidemiology worldwide.

Methods: The study aimed to compare IE epidemiological features and outcomes according to predefined European regions and between two different time periods in the twenty-first century.

Results: IE cases from 13 European countries were included.

Bloodstream Infection, Resistance, and Mortality: Do Solid Organ Transplant Recipients Do Better or Worse?

Background: The prevalence of antimicrobial resistance of () in solid organ transplant (SOT) recipients is higher than that of the general population. However, the literature supporting this statement is scarce. Identifying patients at risk of carbapenem resistance (CR) is of great importance, as CR strains more often receive inappropriate empiric antibiotic therapy, which is independently associated with mortality in bloodstream infections (BSIs).

Bilateral pulmonary septic embolectomy in the setting of multivalvular acute infective endocarditis surgery.

We report a case of multivalvular acute infective endocarditis associated with a bilateral septic pulmonary embolism. The patient underwent aortic and tricuspid valve replacement, mitral valve anterior leaflet debridement and bilateral pulmonary septic embolectomy, followed by a 6-week intravenous antibiotic treatment. We present our multidisciplinary approach for the management of such complex cases.

Emerging issues on endocarditis and the role in therapy of daptomycin plus fosfomycin.

Introduction: Methicillin-resistant and -susceptible (MRSA/MSSA) infections are a major global health-care problem. Bacteremia with exhibits high rates of morbidity and mortality and can cause complicated infections such as infective endocarditis (IE). The emerging resistance profile of is worrisome, and several international agencies have appealed for new treatment approaches to be developed.

Forty-Year Trends in Cardiac Implantable Electronic Device Infective Endocarditis.

Background: Studies investigating cardiac implantable electronic device infective endocarditis (CIED-IE) epidemiological changes and prognosis over long periods of time are lacking.

Methods: Retrospective single cardiovascular surgery center cohort study of definite CIED-IE episodes between 1981-2020. A comparative analysis of two periods (1981-2000 vs 2001-2020) was conducted to analyze changes in epidemiology and outcome over time.

Outpatient Parenteral Antibiotic Treatment vs Hospitalization for Infective Endocarditis: Validation of the OPAT-GAMES Criteria.

Background: Outpatient parenteral antibiotic treatment (OPAT) programs are increasingly used to manage infective endocarditis (IE), but current criteria for indicating OPAT are markedly conservative. We aimed to investigate whether more liberal criteria for indicating OPAT in IE can be safely used.

Methods: This was a prospective multicenter nationwide cohort study (2008-2018).

Optimal Timing for Cardiac Surgery in Infective Endocarditis with Neurological Complications: A Narrative Review.

In patients with infective endocarditis and neurological complications, the optimal timing for cardiac surgery is unclear due to the varied risk of clinical deterioration when early surgery is performed. The aim of this review is to summarize the best evidence on the optimal timing for cardiac surgery in the presence of each type of neurological complication. An English literature search was carried out from June 2018 through July 2022.

Comprehensive management of late mediastinitis involving an aortic Dacron graft.

We present a case of late mediastinitis following surgery for type A aortic dissection. After a thorough preoperative workup, the patient underwent a redo sternotomy, removal of all prosthetic material, and replacement of the aortic root with a homograft. The patient required venoarterial extracorporeal membrane oxygenation and delayed sternal closure for post-postoperative biventricular failure as well as prolonged antibiotic treatment.

Relationship among Subsp. , and Colorectal Neoplasms in Recurrent Endocarditis: A Historical Case Series.

Objectives: The role of colorectal neoplasms (CRN) as a common potential source of recurrent subsp. (SGG) and (EF) endocarditis remains unstudied. We aimed to investigate what proportion of episodes of recurrent endocarditis are caused by a succession of SGG and EF, or vice versa, and to assess the role of a colonic source in such recurrent episodes.

C-reactive protein cut-off for early tocilizumab and dexamethasone prescription in hospitalized patients with COVID-19.

Dexamethasone and tocilizumab have been associated with reduction in mortality, however, the beneficial effect is not for all patients and the impact on viral replication is not well defined. We hypostatized that C-reactive protein (CRP) could help in the identification of patients requiring anti-inflammatory therapy. Patients admitted for > 48 h in our hospital for a confirmed or suspected infection by SARS-CoV-2 from February 2020 to February 2021 were retrospectively evaluated.
