Antibiotic Resistance Trends in Carbapenem-Resistant Gram-Negative Pathogens and Eight-Year Surveillance of XDR Bloodstream Infections in a Western Greece Tertiary Hospital.

: The increased prevalence of antibiotic resistance among Gram-negative bacteria presents a severe public health challenge, leading to increased mortality rates, prolonged hospital stays, and higher medical costs. In Greece, the issue of multidrug-resistant Gram-negative bacteria is particularly alarming, exacerbated by overuse of antibiotics and inadequate infection control measures. This study aimed to detect the prevalence of extensively drug-resistant (XDR) Gram-negative bacteria in a tertiary hospital in Western Greece over the last eight years from 2016 to 2023.

Incidence of Carbapenem-Resistant Gram-Negative Bacterial Infections in Critically Ill Patients with COVID-19 as Compared to Non-COVID-19 Patients: A Prospective Case-Control Study.

Introduction: Critically ill COVID-19 patients hospitalized in intensive care units (ICU) are immunosuppressed due to SARSCoV-2-related immunological effects and are administered immunomodulatory drugs. This study aimed to determine whether these patients carry an increased risk of multi-drug resistant (MDR) and especially carbapenem-resistant Gram-negative (CRGN) bacterial infections compared to other critically ill patients without COVID-19.

Materials And Methods: A prospective case-control study was conducted between January 2022 and August 2023.

Daptomycin Liposomes Exhibit Enhanced Activity against Staphylococci Biofilms Compared to Free Drug.

The purpose of the present study was to investigate the anti-staphylococcal activity of liposomal daptomycin against four biofilm-producing and clinical strains, three of which are methicillin-resistant. Neutral and negatively charged daptomycin-loaded liposomes were prepared using three methods, namely, thin-film hydration (TFH), a dehydration-rehydration vesicle (DRV) method, and microfluidic mixing (MM); moreover, they were characterized for drug encapsulation (EE%), size distribution, zeta-potential, vesicle stability, drug release, and drug integrity. Interestingly, whilst drug loading in THF and DRV nanosized (by extrusion) vesicles was around 30-35, very low loading (~4%) was possible in MM vesicles, requiring further explanatory investigations.

Role of source control in critically ill candidemic patients: a multicenter retrospective study.

Purpose: Candidemia is associated with high mortality especially in critically ill patients. Our aim was to identify predictors of mortality among critically ill patients with candidemia with a focus on early interventions that can improve prognosis.

Methods: Multicenter retrospective study.

Laboratory Surveillance of spp. Bloodstream Infections in a Tertiary University Hospital during a 9-Year Period.

Multidrug-resistant infections have become a threat for public health worldwide. The aim of the present study was to follow-up resistance patterns of spp. bloodstream isolates in a Tertiary University Hospital over the last nine years, from 2014 to 2022.
