Background: Mecillinam (amdinocillin) is active against Gram-negative bacteria. Clinical data on the efficacy of IV mecillinam for severe urinary tract infections is sparse.Objectives: To assess the effectiveness of targeted IV mecillinam compared with other β-lactams for bacteraemia with Escherichia coli and Klebsiella spp. and a urinary tract focus.Patients and Methods: We performed a retrospective cohort study at five university hospitals in the Capital Region of Denmark from 1 January 2012 to 31 December 2017. We used Cox proportional hazard regression to compare the primary composite endpoint (all-cause mortality or bacteraemia recurrence within 30 days) between patients treated with mecillinam versus ampicillin, cefuroxime, piperacillin/tazobactam and meropenem.Results: We included 1129 patients in the primary analysis, of which 146 were given IV mecillinam as targeted treatment. We found no significant difference in the primary endpoint between patients treated with mecillinam versus ampicillin and cefuroxime, but found a higher risk for the primary endpoint in the piperacillin/tazobactam and meropenem groups, with adjusted HRs of 2.22 (95% CI 1.24-3.97, P < 0.01) and 2.48 (95% CI 1.04-5.93, P = 0.04), respectively, compared with mecillinam.Conclusions: The results of this study suggest that IV mecillinam may be a suitable targeted treatment for bacteraemia with a urinary tract focus. However, these results need confirmation by randomized controlled studies. [ABSTRACT FROM AUTHOR]

This article presents a case study of a patient with diabetes who developed a fungal infection in the urinary tract while taking a specific medication. The medication, called an SGLT-2 inhibitor, has been linked to an increased risk of urinary tract infections and genital yeast infections. The article emphasizes the need for more research to understand the connection between fungal infections and the use of SGLT-2 inhibitors in diabetic patients. The text is a correspondence from a researcher at Copenhagen University Hospital and is published by BJU International. [Extracted from the article]

Overdiagnosis of urinary tract infections (UTIs) is one of the most common reasons for the unnecessary use of antibiotics in nursing homes, increasing the risk of missing serious conditions. Various decision tools and algorithms aim to aid in UTI diagnosis and the initiation of antibiotic therapy for residents. However, due to the lack of a clear reference standard, these tools vary widely and can be complex, with some requiring urine testing. As part of the European-funded IMAGINE project, aimed at improving antibiotic use for UTIs in nursing home residents, we have reviewed the recommendations. This review provides a comprehensive summary of the more relevant tools and algorithms aimed at identifying true UTIs among residents living in nursing homes and discusses the challenges in using these algorithms based on updated research. The discussion is based on a relevant medical literature search and synthesis of the findings and published tools to provide an overview of the current state of improving the diagnosis of UTIs in nursing homes. The following topics are covered: prevalence of asymptomatic bacteriuria, diagnostic challenges, clinical criteria, urinary testing, and algorithms to be implemented in nursing home facilities. Diagnosing UTIs in residents is challenging due to the high prevalence of asymptomatic bacteriuria and nonspecific urinary tract signs and symptoms among those with suspected UTIs. The fear of missing a UTI and the perceived antibiotic demands from residents and relatives might lead to overdiagnosis of this common condition. Despite their widespread use, urine dipsticks should not be recommended for geriatric patients. Patients who do not meet the minimum diagnostic criteria for UTIs should be evaluated for alternative conditions. Adherence to a simple algorithm can prevent unnecessary antibiotic courses without compromising resident safety. [ABSTRACT FROM AUTHOR]

Background: Despite the extensive use of antibiotics and the growing challenge of antimicrobial resistance, there has been a lack of substantial initiatives aimed at diminishing the prevalence of infections in nursing homes and enhancing the detection of urinary tract infections (UTIs)., Objective: This study aims to systematize and enhance efforts to prevent health care-associated infections, mainly UTIs and reduce antibiotic inappropriateness by implementing a multifaceted intervention targeting health care professionals in nursing homes., Methods: A before-and-after intervention study carried out in a minimum of 10 nursing homes in each of the 8 European participating countries (Denmark, Greece, Hungary, Lithuania, Poland, Slovakia, Slovenia, and Spain). A team of 4 professionals consisting of nurses, doctors, health care assistants, or health care helpers are actively involved in each nursing home. Over the initial 3-month period, professionals in each nursing home are registering information on UTIs as well as infection and prevention control measures by means of the Audit Project Odense method. The audit will be repeated after implementing a multifaceted intervention. The intervention will consist of feedback and discussion of the results from the first registration, training on the implementation of infection and prevention control techniques provided by experts, appropriateness of the diagnostic approach and antibiotic prescribing for UTIs, and provision of information materials on infection control and antimicrobial stewardship targeted to staff, residents, and relatives. We will compare the pre- and postintervention audit results using chi-square test for prescription appropriateness and Student t test for implemented hygiene elements., Results: A total of 109 nursing homes have participated in the pilot study and the first registration audit. The results of the first audit registration are expected to be published in autumn of 2024. The final results will be published by the end of 2025., Conclusions: This is a European Union-funded project aimed at contributing to the battle against antimicrobial resistance through improvement of the quality of management of common infections based on evidence-based interventions tailored to the nursing home setting and a diverse range of professionals. We expect the intervention to result in a significant increase in the number of hygiene activities implemented by health care providers and residents. Additionally, we anticipate a marked reduction in the number of inappropriately managed UTIs, as well as a substantial decrease in the overall incidence of infections following the intervention., International Registered Report Identifier (irrid): DERR1-10.2196/60099., (©Ana García-Sangenís, Daniela Modena, Jette Nygaard Jensen, Athina Chalkidou, Valeria S Antsupova, Tina Marloth, Anna Marie Theut, Beatriz González López-Valcárcel, Fabiana Raynal, Laura Vallejo-Torres, Jesper Lykkegaard, Malene Plejdrup Hansen, Jens Søndergaard, Jonas Kanstrup Olsen, Anders Munck, András Balint, Ria Benko, Davorina Petek, Nina Sodja, Anna Kowalczyk, Maciej Godycki-Cwirko, Helena Glasová, Jozef Glasa, Ruta Radzeviciene Jurgute, Lina Jaruseviciene, Christos Lionis, Marilena Anastasaki, Agapi Angelaki, Elena Petelos, Laura Alvarez, Marta Ricart, Sergi Briones, Georg Ruppe, Ramon Monfà, Anders Bjerrum, Carl Llor.

This is a case report of the first two cases of Candida auris in Denmark. Patient 1 was known to be colonized with C. auris when transferred from a foreign hospital to a Danish hospital. The patient was isolated during the entire hospitalization and the room was thoroughly cleaned after discharge. Patient 2 who had no travel history spent five hours in the room of Patient 1 after disinfection. One month later, C. auris was found in the blood of Patient 2. Transmission from Patient 1 to Patient 2 must be suspected.
