This study aims to describe the clinical use of cefazolin and flucloxacillin, focussing on discontinuation or change of anti-infective agent due to adverse events.

Effectiveness of outpatient parenteral antimicrobial therapy (OPAT) for patients with cranial infection.

Objective: Outpatient parenteral antimicrobial therapy (OPAT) is a well-established and cost-effective method for improving the efficient use of healthcare resources. However, only a few centres in Germany perform it. Here we analysed OPAT for the treatment of patients with cranial infections in our neurosurgical department.

Safety and feasibility of outpatient parenteral antimicrobial therapy for patients with spinal infection.

Outpatient parenteral antimicrobial therapy (OPAT) is a cost-effective method of administering intravenous antimicrobial therapy. Although OPAT is well established in the UK and US healthcare systems, few centres in Europe perform it. Here we analysed OPAT for the treatment of patients with spinal infections at our institution.

Clinical characteristics and outcome of Mycobacterium chimaera infections after cardiac surgery: systematic review and meta-analysis of 180 heater-cooler unit-associated cases.

Objectives: Since 2013, heater-cooler unit (HCU) associated Mycobacterium chimaera infections linked to a global outbreak have been described. These infections were characterised by high morbidity and mortality due to delayed diagnosis, as well as challenges in antimycobacterial and surgical therapy. This study aimed to investigate the clinical characteristics and outcome of published cases of HCU-associated M.

Impact of colonization with multidrug-resistant organisms on antibiotic prophylaxis in patients with cirrhosis and variceal bleeding.

Background: The efficacy of antibiotic prophylaxis to prevent rebleeding or infection after variceal bleeding in patients with liver cirrhosis colonized with multidrug-resistant organisms (MDROs) is unknown.

Methods: In this retrospective study, patients with liver cirrhosis and endoscopically confirmed variceal bleeding who were treated at a tertiary care center in Germany and were screened for MDROs at the time of bleeding were eligible for inclusion. Efficacy of antibiotic prophylaxis was evaluated in patients stratified according to microbiological susceptibility testing.

Exclusion of Mucorales Co-Infection in a Patient with Sinusitis by Fluorescence In Situ Hybridization (FISH).

Invasive fungal infections are associated with increased mortality in hematological patients. Despite considerable advances in antifungal therapy, the evaluation of suspected treatment failure is a common clinical challenge requiring extensive diagnostic testing to rule out potential causes, such as mixed infections. We present a 64-year-old patient with secondary AML, diabetes mellitus, febrile neutropenia, and sinusitis.

Development and validation of a simplified risk score for the prediction of critical COVID-19 illness in newly diagnosed patients.

Scores to identify patients at high risk of progression of coronavirus disease (COVID-19), caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), may become instrumental for clinical decision-making and patient management. We used patient data from the multicentre Lean European Open Survey on SARS-CoV-2-Infected Patients (LEOSS) and applied variable selection to develop a simplified scoring system to identify patients at increased risk of critical illness or death. A total of 1946 patients who tested positive for SARS-CoV-2 were included in the initial analysis and assigned to derivation and validation cohorts (n = 1297 and n = 649, respectively).

Disseminated disease due to non-tuberculous mycobacteria in HIV positive patients: A retrospective case control study.
