The objective of this study was to characterize frailty and resilience in people evaluated for Post-Acute COVID-19 Syndrome (PACS), in relation to quality of life (QoL) and Intrinsic Capacity (IC). This cross-sectional, observational, study included consecutive people previously hospitalized for severe COVID-19 pneumonia attending Modena (Italy) PACS Clinic from July 2020 to April 2021. Four frailty-resilience phenotypes were built: "fit/resilient", "fit/non-resilient", "frail/resilient" and "frail/non-resilient".

Introduction: Reports regarding the external validity of randomized controlled trials (RCTs) are scarce. We aimed to assess the population external validity of an investigator-initiated RCT on the duration of antibiotics for the treatment of Gram-negative bacteremia by comparing patients included in the RCT to patients that were not included in the trial.

Methods: Hospitalized patients with Gram-negative bacteremia were recruited into an RCT and randomized to receive 7 or 14 days of covering antibiotic therapy in Israel and Italy from 2013 to 2017.

Article Synopsis
  • Carbapenem-resistant Acinetobacter baumannii (CRAB) poses a significant threat in healthcare settings, with over a 40% mortality rate among critically ill patients; this review focuses on the best infection prevention and control (IPC) strategies to combat its spread in hospitals.
  • A critical review of literature from the past 10 years assessed IPC measures in various settings, with the majority of studies centered on ICU outbreaks, showing high mortality rates up to 50%.
  • The review found that while some IPC measures like environmental disinfection were universally applied, others varied significantly by study and setting, emphasizing that targeted 'search and destroy' strategies are key to effective CRAB control.

Ventilator-associated pneumonia (VAP) in critically ill patients with COVID-19 represents a very huge global threat due to a higher incidence rate compared to non-COVID-19 patients and almost 50% of the 30-day mortality rate. was the first pathogen involved but uncommon non-fermenter gram-negative organisms such as and have emerged as other potential etiological causes. Against carbapenem-resistant gram-negative microorganisms, Ceftazidime/avibactam (CZA) is considered a first-line option, even more so in case of a ceftolozane/tazobactam resistance or shortage.

The coronavirus disease 2019 (COVID-19)-pandemic-related overload of health systems has compromised the application of antimicrobial stewardship (AS) models and infection prevention and control (IPC) programs. We aimed to evaluate the impact of COVID-19 on antimicrobial consumption (AC) and antimicrobial resistance (AMR) in the University Hospital of Modena. A time series analysis with an autoregressive integrated moving average model was conducted from January 2015 to October 2021 to evaluate the AC in the whole hospital and the intensive care unit (ICU), the incidence density (ID) of bloodstream infections (BSIs) due to the main multidrug-resistant organisms, and of infections (CDIs).

Background: A proposal has recently been advanced to change the traditional definition of nonalcoholic fatty liver disease to metabolic-associated fatty liver disease (MAFLD), to reflect the cluster of metabolic abnormalities that may be more closely associated with cardiovascular risk. Long coronavirus disease 2019 (COVID-19) is a smoldering inflammatory condition, characterized by several symptom clusters. This study aims to determine the prevalence of MAFLD in patients with postacute COVID syndrome (PACS) and its association with other PACS-cluster phenotypes.

Article Synopsis
  • The study analyzed the 28-day mortality rates of hospitalized COVID-19 patients during the first wave (February-May 2020) and the second wave (October-December 2020) in Italy.
  • A total of 1,472 patients were included, revealing a 28-day mortality rate of 20.0% in the first wave and a reduced rate of 14.2% in the second wave, indicating a 36% improvement in survival.
  • The findings suggest that, despite various factors, there were significant advancements in patient outcomes during the second wave, warranting further investigation into the reasons for this trend.

Background: Herpes simplex 1 co-infections in patients with COVID-19 are considered relatively uncommon; some reports on re-activations in patients in intensive-care units were published. The aim of the study was to analyze herpetic re-activations and their clinical manifestations in hospitalized COVID-19 patients, performing HSV-1 PCR on plasma twice a week.

Methods: we conducted a prospective, observational, single-center study involving 70 consecutive patients with severe/critical SARS-CoV-2 pneumonia tested for HSV-1 hospitalized at Azienda Ospedaliero-Universitaria of Modena.

Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) infection outbreaks are difficult to control and sometimes require cohorting of CRAB-positive patients or temporary ward closure for environmental cleaning. We aimed at controlling the deadly 2018 CRAB outbreak in a 12 bed- intensive care unit (ICU) including 9 beds in a 220 m open space. We implemented a new multimodal approach without ward closure, cohorting or temporarily limiting admissions.

Background: The benefit of tocilizumab on mortality and time to recovery in people with severe COVID pneumonia may depend on appropriate timing. The objective was to estimate the impact of tocilizumab administration on switching respiratory support states, mortality and time to recovery.

Methods: In an observational study, a continuous-time Markov multi-state model was used to describe the sequence of respiratory support states including: no respiratory support (NRS), oxygen therapy (OT), non-invasive ventilation (NIV) or invasive mechanical ventilation (IMV), OT in recovery, NRS in recovery.

The aim of this study was to evaluate both positive outcomes, including reduction of respiratory support aid and duration of hospital stay, and negative ones, including mortality and a composite of invasive mechanical ventilation or death, in patients with coronavirus disease 2019 (COVID-19) pneumonia treated with or without oral darunavir/cobicistat (DRV/c, 800/150 mg/day) used in different treatment durations. The secondary objective was to evaluate the percentage of patients treated with DRV/c who were exposed to potentially severe drug-drug interactions (DDIs) and died during hospitalization. This observational retrospective study was conducted in consecutive patients with COVID-19 pneumonia admitted to a tertiary care hospital in Modena, Italy.

This Mini Review of the literature aimed to assess the role of tocilizumab for the treatment of severe coronavirus disease 2019 (COVID-19). Based on the available scientific evidence, it is not clear to date what is the best therapeutic strategy for the treatment of COVID-19. Since SARS-CoV-2 infection stimulates a vigorous proinflammatory response and may cause the so-called "cytokine storm", immunomodulator drugs have been investigated as potential treatment for severe COVID-19 pneumonia.

Article Synopsis
  • COVID-19 patients with pneumonia display significant alterations in their monocytes, which are often overlooked despite their critical role in inflammation.
  • Analysis showed these monocytes exhibit mitochondrial dysfunction, decreased respiration capabilities, and reduced aerobic glycolysis, indicating impaired energy production.
  • There is also a notable shift in monocyte types, with an increase in pro-inflammatory and immature monocytes, along with elevated levels of inflammatory markers in the blood, underscoring their contribution to the disease's immune response.

Purpose: Post-neurosurgical infection caused by extensively drug resistant Pseudomonas aeruginosa (XDR-PA) are becoming a matter of great concern due to limited therapeutic options. Although not approved for these indications, the new BetaLactam-BetaLactamase Inhibitor combinations (BLBLIs) could represent a valid salvage treatment. We describe one nosocomial meningitis and two cervical osteomyelitis due to an XDR-PA who were treated with ceftazidime/avibactam (CZA) and ceftolozane/tazobactam (C/T) and review the literature.
