OBJECTIVES:We aimed to assess the impact of COVID-19 on antibiotic consumption (AMC) and antimicrobial resistance (AMR) in the new epidemiological scenario from a cross-national perspective. METHODS:A quasi-experimental retrospective multicentre ecological study was conducted to explore the impact of COVID-19 on AMC and AMR using routinely generated retrospective time series data. This study included nine Healthcare University Hospitals from Europe and Israel on behalf QUantifying change in Antibiotic Resistance, ANTibiotic use, and INfection control during COVID-19 Epidemics project. Total effects were defined as the difference between the pre-COVID-19 period (ranging from January 2015 or January 2016 to February 2020) and during the COVID-19 pandemic period (March 2020 to July 2021 or December 2021). The outcomes were incidence density (ID) of carbapenem-resistant Acinetobacter baumannii, carbapenem-resistant Klebsiella pneumoniae, extended-spectrum beta-lactamase-producing Escherichia coli, vancomycin-resistant enterococci (VRE), methicillin-resistant Staphylococcus aureus, carbapenem-resistant Pseudomonas aeruginosa and Clostridioides difficile, as monthly isolates per 1000 patient days and the monthly AMC ranked according to the Access, Watch, and Reserve WHO classification system. RESULTS:We assessed 15.9 million total hospital bed days, 315 736 COVID-19 bed days, 52 557 monthly bacterial isolates, and 461 739 monthly antimicrobial defined daily doses. The COVID-19 pandemic had a significant impact on the consumption of overall hospital antibiotics combined in all centres except two. Prescriptions for piperacillin/tazobactam, glycopeptides, and ceftazidime/avibactam increased, whereas third-generation cephalosporins, macrolides, and fluoroquinolones returned to pre-pandemic levels after an initial surge, in all centres. A positive relationship between the pandemic intensity and VRE ID was observed in 6 of 9 (66%) centres followed by methicillin-resistant S. aureus-ID and carbapenem-resistant P. aeruginosa-ID 3 of 4 (44%) for both. A negative relationship was found for extended-spectrum beta-lactamase-producing E. coli ID. DISCUSSION:The COVID-19 pandemic was associated with higher usage of broad-spectrum antibiotics and higher incidence of multidrug-resistant bacteria, with great variability by countries. These results could support international action plans that embed AMR as a priority in the post-COVID-19 era.

PURPOSE OF REVIEW:Healthcare-associated infections (HAIs) remain a critical challenge in intensive care units (ICUs) due to the high prevalence of invasive procedures, vulnerable patient populations, and the increasing threat of antimicrobial-resistant organisms (MDROs). This review synthesizes current evidence on infection prevention and control (IPC) strategies in the ICU setting, highlighting recent findings and innovations in this evolving field, particularly in light of the impact of the COVID-19 pandemic. RECENT FINDINGS:The review outlines ten key IPC strategies for ICUs, categorizing them into horizontal (universal) and vertical (pathogen-specific) approaches. Recent literature emphasizes the importance of enhanced hand hygiene compliance through motivational interventions and feedback. The role of selective decontamination strategies remains debated, with evidence suggesting potential benefits in specific patient subgroups. Vertical strategies, including active screening for MDROs and per-pathogen bundles, are increasingly being tailored based on local epidemiology and pathogen characteristics. Studies suggest that de-escalating routine contact precautions for certain MDROs like Methicillin-resistant Staphylococcus aureus and Vancomycin-resistant Enterococcus may be safe in settings with robust horizontal measures. Conversely, intensified "search and destroy" strategies show promise in controlling carbapenem-resistant Acinetobacter baumannii outbreaks. SUMMARY:Effective IPC in the ICU requires a multifaceted and adaptable approach, integrating both universal precautions and targeted interventions against specific pathogens. While consistent implementation of horizontal strategies like hand hygiene is foundational, tailoring vertical strategies based on local MDRO epidemiology and patient risk profiles is crucial. Future research should focus on harmonizing IPC policies, optimizing screening methods, and evaluating the long-term impact of combined IPC and antimicrobial stewardship programs to improve patient outcomes and mitigate the spread of antimicrobial resistance in critical care settings.

Objective: People with HIV (PWH) have high risk of liver fibrosis. We investigated the effect of weight gain and metabolic dysfunction-associated steatotic liver disease (MASLD) on liver fibrosis dynamics. Design: Multicenter cohort study. Methods: Fibrosis progression was defined as development of significant fibrosis [liver stiffness measurement (LSM) >= 8 kPa], or transition to cirrhosis (LSM >= 13 kPa), for those with significant fibrosis at baseline. Fibrosis regression was defined as transition to LSM less than 8 kPa, or to LSM less than 13 kPa for those with cirrhosis at baseline. MASLD was defined as hepatic steatosis (controlled attenuation parameter >248 dB/m) with at least one metabolic abnormality. A continuous-time multistate Markov model was used to describe transitions across fibrosis states. Results: Among 1183 PWH included from three centers (25.2% with viral hepatitis coinfection), baseline prevalence of significant fibrosis and MASLD was 14.4 and 46.8%, respectively. During a median follow-up of 2.5 years (interquartile range 1.9-3.5), the incidence rate of fibrosis progression and regression was 2.8 [95% confidence interval (CI) 2.3-3.4] and 2.2 (95% CI 1.9-2.6) per 100 person-years, respectively. In Markov model, weight gain increased the odds of fibrosis progression [odds ratio (OR) 3.11, 95% CI 1.59-6.08], whereas weight gain (OR 0.30, 95% CI 0.10-0.84) and male sex (OR 0.32, 95% CI 0.14-0.75) decreased the odds of fibrosis regression. On multivariable Cox regression analysis, predictors of fibrosis progression were weight gain [adjusted hazard ratio (aHR) 3.12, 95% CI 1.41-6.90] and MASLD (aHR 2.72, 95% CI 1.05-7.02). Conclusion: Fibrosis transitions are driven by metabolic health variables in PWH, independently of viral hepatitis coinfection and antiretroviral class therapy.

Background:Intravenous drug users (IDUs) have a high risk of developing skin and soft tissue infections such as erysipelas, abscesses, and less frequently necrotizing fasciitis (NF) or gas gangrene. Rarely, the cause of the infection is microorganisms residing in the oral cavity and can lead to life-threatening infections.Methods:We describe the case of a 43-year-old man intravenous drug user (IDU) who was admitted for intense leg pain following an injection of cocaine at that site.Results:A clinical and radiological diagnosis of NF was made, so the patient was started on empirical antibiotic therapy and underwent surgical fasciotomy (after 8 hours from admission). Prevotella denticola was isolated from multiple intraoperative specimens and was resistant to initial antimicrobial therapy. The man, suffering from periodontal disease, reported sucking the syringe several times to unblock it. Both fasciotomy surgery and adjustment of antimicrobial therapy enabled therapeutic success.Conclusions:In IDUs the risk of deep skin and soft tissue infections is high and may be aggravated by contamination with oral microorganisms. The choice of empirical antibiotic treatment should include agents active against oral cavity anaerobes, such as P. denticola.

Introduction: There is scarce evidence in literature of what should be the best antimicrobial treatment for bloodstream infections (BSIs) sustained by Stenotrophomonas maltophilia , a peculiar pathogen that intrinsically withstands to most of the available antibiotics.Results and conclusion: Here, we describe a challenging case of a persistent S. maltophilia BSI due to septic thrombosis successfully treated with the addition of the novel siderophore cephalosporin cefiderocol to an only partially effective levofloxacin regimen. Additionally, an intra-lock therapy with trimethoprim/sulfamethoxazole was selected as a strategy to prevent recurrence of infection since complete source control was not possible. The serum bactericidal assay was also used to corroborate the in vivo efficacy of the adopted combination therapy.& COPY; 2023 The Authors.

BACKGROUND AND AIM:simulation became gradually pivotal in training of health professionals: indeed, it showed an improvement in practical skill of the trainees compared to theoretical lectures. Among others, ACLS (advance cardiovascular life support) courses are now one of the standard learning practices most spread around the world. The primary aim of this study is to evaluate both the level of satisfaction and the clinical thinking that the trainees perceived during an ACLS course. This was performed via the SSE validated scale (Satisfaction with simulation experience scale). The secondary aim was to evaluate if demographics affect the aforementioned perceived satisfaction.METHODS:a SSE questionnaire was distributed after the ACLS section of practical scenarios, just before the end of the course and of the practical test.RESULTS:72 questionnaires have been collected. The sample was constituted by 68.1% of females, 44,4% by nurses without a master's degree, and 52,8% personnel that works outside of a critical care setting. QTOT Median score was 89 (IQR=86-90), DTOT Median's 45 (IQR= 44.25-45), RTOT Median's 25 (IQR=22-25), LTOT Median was 20 (IQR=19-20).  Conclusions: The ACLS course attains a high grade of satisfaction on all of the three aspects evaluated by the questionnaire. The perception was not influenced by the demographics.

Background: Despite the global efforts to antagonize carbapenem-resistant Acinetobacter baumannii (CRAB) spreading, it remains an emerging threat with a related mortality exceeding 40% among critically ill patients. The purpose of this review is to provide evidence concerning the best infection prevention and control (IPC) strategies to fight CRAB spreading in endemic hospitals. Methods: The study was a critical review of the literature aiming to evaluate all available studies reporting IPC measures to control CRAB in ICU and outside ICU in both epidemic and endemic settings in the past 10 years. Results: Among the 12 included studies, the majority consisted of research reports of outbreaks mostly occurred in ICUs. The reported mortality reached 50%. Wide variability was observed related to the frequency of application of recommended CRAB IPC measures among the studies: environmental disinfection (100%); contact precautions (83%); cohorting staff and patients (75%); genotyping (66%); daily chlorhexidine baths (58%); active rectal screening (50%); closing or stopping admissions to the ward (33%). Conclusions: Despite effective control of CRAB spreading during the outbreaks, the IPC measures reported were heterogeneous and highly dependent on the different setting as well as on the structural characteristics of the wards. Reinforced ‘search and destroy’ strategies both on the environment and on the patient, proved to be the most effective measures for permanently eliminating CRAB spreading.
