Article Synopsis
  • - After COVID-19 began, there was a significant increase in invasive fungal infections globally, but the specific situation in Greece regarding fungaemias remains unclear.
  • - An ongoing outbreak in a Greek hospital has led to 89 episodes of bloodstream infections over nearly three years, with these episodes occurring in waves linked to previous colonization peaks.
  • - Most fungal isolates were found to be resistant to fluconazole but sensitive to other antifungals, highlighting the importance of infection control and careful use of antifungal treatments to prevent resistance.

Article Synopsis
  • Aging affects how driving pressure impacts mortality in patients with ARDS, particularly highlighting that this relationship may be stronger in older individuals, especially those aged 80 and above.!* -
  • A study analyzed data from over 4,500 ARDS patients and found that the difference in driving pressure between those who survived and those who did not varied significantly with age, indicating a critical age-related factor in mortality risk.!* -
  • The results suggest that a personalized approach to mechanical ventilation based on a patient's age could be beneficial for managing ARDS, as certain thresholds for driving pressure may have different implications for older populations.!*

Article Synopsis
  • Nosocomial pneumonia, particularly hospital-acquired and ventilator-associated forms, is the top killer from hospital infections in critically ill patients, significantly exacerbated by multi-drug-resistant (MDR) Gram-negative bacteria (GNB).
  • The rise of MDR-GNB pneumonia results in delayed treatments, longer hospital stays, and higher rates of illness and death, compounded by the toxic side effects of traditional antibiotics.
  • Recently approved novel antibiotics show promise in treating MDR-GNB pneumonia, but rising antibiotic resistance poses a global challenge, emphasizing the need for careful usage to extend their effectiveness and evaluating their clinical efficacy specifically for patients with nosocomial pneumonia.

Article Synopsis
  • The COVID-19 pandemic resulted in a notable increase in invasive fungal infections among critically ill patients, leading to new diagnostic and treatment challenges.
  • This review specifically examines the rise of mold infections caused by certain species in COVID-19 patients, detailing their incidence, causes, and management.
  • The study emphasizes that traditional risk factors for these infections were often overlooked in COVID-19 cases, resulting in poorer outcomes for patients with these co-infections compared to those without.

Article Synopsis
  • * Invasive infections are tied more to procedures like mechanical ventilation than to traditional risk factors seen in other patients, highlighting the unique challenges posed by COVID-19.
  • * The review emphasizes the concerning rise in fluconazole-resistant fungal strains and how these co-infections significantly worsen patient outcomes, increasing morbidity and mortality rates.

Article Synopsis
  • Gram-negative bacteria have increasingly shown resistance to antimicrobials over recent decades, posing significant challenges in hospital settings worldwide.
  • In response, researchers and the pharmaceutical industry have introduced several new antimicrobials in the last five years, including cefiderocol and omadacycline, which are designed to tackle resistant bacterial strains.
  • The review examines the properties and clinical data of these new drugs, as well as other promising agents currently in advanced phase 3 clinical trials, like aztreonam-avibactam and sulopenem.

(), an important pathogen in immuno-compromised patients, has recently gained attention in patients admitted in intensive care units (ICU). We sought to investigate clinical features of infections caused by in ICU patients and identify risk factors for mortality. We conducted a retrospective study in two multivalent non-COVID-19 ICUs of tertiary-teaching hospitals in Greece and Spain, including patients with isolated from at least one clinical specimen along with clinical signs of infection.

(1) Background: It is not known whether different daily dosing schemes have different effects on colistin nephrotoxicity. We examined the effect of once- versus twice- or thrice-daily doses of colistin on renal function. (2) Methods: We performed a multicenter retrospective cohort study of hospitalized patients with a baseline glomerular filtration rate ≥ 50 mL/min who received intravenously the same colistin dose once (regimen A), twice (regimen B) or thrice daily (regimen C).

The objectives of this study were to investigate the incidence of candidemia, as well as the factors associated with species distribution and fluconazole resistance, among patients admitted to the intensive care unit (ICU) during the COVID-19 pandemic, as compared to two pre-pandemic periods. All patients admitted to the ICU due to COVID-19 from March 2020 to October 2021, as well as during two pre-pandemic periods (2005-2008 and 2012-2015), who developed candidemia, were included. During the COVID-19 study period, the incidence of candidemia was 10.

Background: Macrophage activation-like syndrome (MALS) and complex immune dysregulation (CID) often underlie acute respiratory distress (ARDS) in COVID-19. We aimed to investigate the effect of personalized immunotherapy on clinical improvement of critical COVID-19.

Methods: In this open-label prospective trial, 102 patients with ARDS by SARS-CoV-2 were screened for MALS (ferritin >4,420 ng/mL) and CID (ferritin ≤4,420 ng/mL and low human leukocyte antigen (HLA)-DR expression on CD14-monocytes).

Introduction: Invasive pulmonary aspergillosis is an emerging complication among intensive care unit (ICU) patients with COVID-19 (CAPA). In the present study, all CAPA cases during the first year of the pandemic were reviewed in critically ill patients at a 650-bed tertiary Greek COVID-19 reference hospital.

Methods: Data regarding patients admitted to the ICU of Attikon Hospital in Athens, Greece, between 22 March 2020 and 28 February 2021 with a positive PCR for SARS-CoV-2 infection were reviewed.

Background: De-escalation of empirical antimicrobial therapy, a key component of antibiotic stewardship, is considered difficult in ICUs with high rates of antimicrobial resistance.

Objectives: To assess the feasibility and the impact of antimicrobial de-escalation in ICUs with high rates of antimicrobial resistance.

Methods: Multicentre, prospective, observational study in septic patients with documented infections.

The incidence of gram-negative multidrug-resistant (MDR) bacterial pathogens is increasing in hospitals and particularly in the intensive care unit (ICU) setting. The clinical consequences of infections caused by MDR pathogens remain controversial. The purpose of this review is to summarize the available data concerning the impact of these infections on mortality in ICU patients.

Introduction: Invasive fungal infections are alarmingly common in intensive care unit patients; invasive fungal infections are associated with increased morbidity and mortality. Risk factors are the increased use of indwelling central venous catheters, the use of broad spectrum antibiotics, parenteral nutrition, renal replacement therapy and immunosuppression. Diagnosis of these infections might be complicated, requiring tissue cultures.
