Ciprofloxacin for the Treatment of Infections Caused by Carbapenemase-Producing Gram-Negative Bacteria.

There is no experience with ciprofloxacin for the treatment of carbapenemase-producing Gram-negative bacteria (CP-GNB) infections. This is a retrospective single-centre study where we describe the clinical evolution of all consecutive adult patients who received ciprofloxacin monotherapy for the treatment of CP-GNB infections. Primary outcomes were clinical failure (defined as death, lack of clinical improvement or a switch to another drug) at day 14 and 30-day all-cause mortality.

Antibiotic Efficacy against Methicillin-Susceptible Staphylococcus aureus Biofilms on Synthetic and Biological Vascular Grafts.

Background: Biofilm formation is one of the greatest challenges encountered in vascular graft infections. Our aim is to compare the efficacy of 5 antibiotics against methicillin-susceptible Staphylococcus aureus (MSSA) biofilms on the surface of 4 vascular grafts.

Methods: In vitro study of 2 clinical MSSA strains (MSSA2 and MSSA6) and 4 vascular grafts (Dacron, Dacron-silver-triclosan (DST), Omniflow-II, and bovine pericardium).

New developments in infective endocarditis.

Infective endocarditis is a continually evolving disease. Present-day patients differ significantly from those treated a few decades ago: they tend to be older and have more comorbidities and health care-related episodes, while new groups of patients have emerged with new types of endocarditis, such as those affecting patients with percutaneous valve prostheses. There have also been changes in diagnostic techniques.

Use of oxazolidinones (linezolid or tedizolid) for the treatment of breast infections. A case series from a tertiary referral hospital.

Objectives: Mastitis is mainly caused by Gram-positive bacteria and usually involves treatment with beta-lactam antibiotics and clindamycin. Oxazolidinones show good results in the treatment of skin and soft tissue infections (SSTIs) due to its pharmacokinetic characteristics. We aimed to describe clinical characteristics and outcomes of patients who received oxazolidinones for the treatment of SSTIs of the mammary tissue.

Impact of Diabetic Foot Multidisciplinary Unit on Incidence of Lower-Extremity Amputations by Diabetic Foot.

Background: One of the most devastating complications of diabetes is diabetes-related foot disease (DFD), which is a priority for public health systems. The 2016-2020 Catalonia Health Plan aimed to reduce the incidence of total and major lower-extremity amputations (LEAs) due to DFD by 10% in the population aged 45-74 years. The aim of the present study was to compare the incidence of LEA-DFD 5 years before and after the creation of the Diabetic Foot Multidisciplinary Unit at our Hospital.

Transcatheter aortic valve replacement for acute aortic regurgitation due to infective endocarditis complicated with a perivalvular abscess: a case report.

Background: Infective endocarditis is a life-threatening disease associated with high mortality. Appropriate antimicrobial treatment and cardiac surgery, when indicated, are closely related to prognosis. When cardiac surgery is contraindicated, prognosis worsens dramatically.

Methicillin-Susceptible Staphylococcus aureus Biofilm Formation on Vascular Grafts: an Study.

The aim of this study was to quantify biofilm formation by methicillin-susceptible Staphylococcus aureus (MSSA) on the surfaces of different types of commonly used vascular grafts. We performed an study with two clinical strains of MSSA (MSSA2 and MSSA6) and nine vascular grafts: Dacron (Hemagard), Dacron-heparin (Intergard heparin), Dacron-silver (Intergard Silver), Dacron-silver-triclosan (Intergard Synergy), Dacron-gelatin (Gelsoft Plus), Dacron plus polytetrafluoroethylene (Fusion), polytetrafluoroethylene (Propaten; Gore), Omniflow II, and bovine pericardium (XenoSure). Biofilm formation was induced in two phases: an initial 90-minute adherence phase and a 24-hour growth phase.

Strengths and limitations of patient registries in infective endocarditis.

Background: Infective endocarditis (IE) is a serious albeit relatively infrequent disease. Given the paucity of cases, particularly in non-referral centres, patient registries have progressively gained relevance to inform about the epidemiology, clinical presentation, and natural history of IE in the last two decades. Although they have become key to advancing knowledge of IE, registries also have shortcomings that lead to relevant consequences that are often overlooked.

Impact of F-FDG-PET/CT on the management of Staphylococcus aureus bacteraemia: a retrospective observational study.

Objectives: To assess the impact of F-FDG-PET/CT on the diagnosis and management of patients with Staphylococcus aureus bacteraemia (SAB).

Methods: Post hoc analysis of a prospective cohort of consecutive adult patients diagnosed with SAB (January 2013-December 2017). Patients who underwent F-FDG-PET/CT at the discretion of the attending physician were included.

Confirmation of preeclampsia-like syndrome induced by severe COVID-19: an observational study.

Background: Since the outbreak of the COVID-19 pandemic, some studies have reported an increased preeclampsia incidence in pregnant women with SARS-CoV-2 infection. Several explanations for this association have been proposed, including a preeclampsia-like syndrome induced by severe COVID-19. This syndrome was described in a small case series and has not been confirmed in larger studies, and its effect on perinatal outcomes has not been studied.

Ceftazidime-Avibactam plus Aztreonam for the Treatment of Infections by VIM-Type-Producing Gram-Negative Bacteria.

This is a retrospective single-center study of 24 patients who received ceftazidime-avibactam plus aztreonam (CZA/ATM) for the treatment of VIM-type-producing Gram-negative bacillus (GNB) infections. The bacteria isolated were in 22 patients and Pseudomonas aeruginosa in 2. Sixteen out of 19 isolates showed synergistic activity.

Nosocomial COVID-19. Prospective study in a referral hospital.

Background And Objective: The objective was to describe the clinical characteristics and prognosis of patients with nosocomial SARS-CoV-2 infection.

Methods: An observational and prospective study was performed in a referral hospital. We included all adult patients diagnosed with nosocomial SARS-CoV-2 infection in October 2020.

Early outcomes in adults hospitalized with severe SARS-CoV-2 infection receiving tocilizumab.

Background: Modulation of the immune system to prevent lung injury is being widely used against the new coronavirus disease (COVID-19). The primary endpoint was mortality at 7 days after tocilizumab administration. Secondary endpoints were admission to the intensive care unit, development of ARDS and respiratory insufficiency among others.
