Article Synopsis
- This study compares two methods for drying endoscopes after disinfection: a standard drying method (SD) using an endoscope washer-disinfector (EWD) and a novel drying method (ND) using a special device with laminar and turbulent airflow.
- Results showed that the ND was more effective, with no residual water left in endoscope channels compared to 90% in the SD group, and significantly less bacterial contamination after 14 days.
- The ND also reduced drying time from over 16 minutes to under 6 minutes, highlighting its efficiency and potential as a better alternative for reprocessing flexible endoscopes.
Moulds are ubiquitous components of outdoor and indoor air and local conditions, temperature, humidity and season can influence their concentration in the air. The impact of these factors on mould exposure in hospitals and the resulting risk of infection for low to moderately immunocompromised patients is unclear. In the present retrospective analysis for the years 2018 to 2022, the monthly determined mould contamination of the outdoor and indoor air at the University Hospital Frankfurt am Main is compared with the average air temperature and the relative humidity.

- A study investigated risk factors for wound infections in patients who underwent percutaneous endoscopic gastrostomy (PEG) insertions, tracking over 600 cases for three years.
- Of those studied, 25% developed wound infections, with higher risks associated with nicotine use, history of ischemic stroke, and head and neck cancer.
- The most common bacteria found in these infections were Enterobacterales, and the study concluded that antibiotic prophylaxis did not significantly reduce infection rates, indicating a need for better clinical practices.
Article Synopsis
- Following the onset of the Ukraine war in February 2022, many Ukrainians sought refuge in European countries, prompting an investigation into their health conditions upon arrival.
- A study conducted at the University Hospital Frankfurt from March to June 2022 analyzed 103 Ukrainian patients, discovering that 16.5% of them carried multidrug-resistant Gram-negative bacteria, including carbapenem-resistant strains.
- The findings highlight the need for hospitals to implement infection control strategies for Ukrainian patients, especially those with war injuries, to manage the increased risk of multidrug-resistant infections and prevent the spread of these dangerous bacteria.
Multidrug-resistant (MDR) Pseudomonas aeruginosa increasingly causes health care-associated infections. In this study, we determined the activity of ceftolozane-tazobactam, ceftazidime-avibactam, and cefiderocol against 223 MDR P. aeruginosa clinical isolates recovered from 2013 to 2017 at the University Hospital Frankfurt by using MIC test strips.
