Objectives: Until July 2016, vancomycin-resistantEnterococcus faecium (VREfm) was sporadically detected in Odense University Hospital, Denmark. After July 2016, the number of VREfm cases increased. This study aimed to apply a core genome multilocus sequence typing (cgMLST) scheme for E. faecium to type and analyse VREfm isolates collected at a single Danish hospital and to compare the results with cgMLST data from other regions of Denmark to trace transmission.
Methods: A total of 38 VREfm clinical isolates from inpatients at the hospital in the period January 2014 through June 2017 were included in the study and analysed using whole-genome sequencing. Use of SeqSphere + software was initiated from the beginning of June 2017 to obtain MLST, cgMLST and epi curves. Admission histories were incorporated and national surveillance data on cgMLST were used to identify transmission routes.
Results: Six different sequence types (STs) were identified, the most frequent being ST80, ST117 and ST203. cgMLST subdivided the 38 isolates into 18 different complex types (CTs) with 13 isolates (34%) belonging to ST80-CT993. Epi curves indicated transmission of ST80-CT993 in several departments. Transmission from patients transferred from other hospitals was not identifiable. Infection control interventions launched in one department ended the outbreak.
Conclusion: The high resolution of cgMLST allowed for detailed interpretation with evidence of nosocomial transmission of specific CTs. cgMLST made it easy to compare our local isolates with national findings, thereby clarifying transmission routes. Supplemented with admission histories, cgMLST targeted the epidemiological investigation and delineated the expensive and time-consuming infection control interventions.

Background: Achilles tendon rupture is a common orthopedic injury, with an annual incidence of 11-37 per 100000 people, significantly impacting daily life. Minimally invasive surgery, increasingly favored for its reduced risks and comparable fixation strength to open surgery, addresses these challenges. Despite advantages like accelerated recovery, perioperative care poses emotional support, pain management, and rehabilitation challenges, impacting treatment efficacy and patient experience.

Infectious bone defects present a significant clinical challenge, characterized by infection, inflammation, and subsequent bone tissue destruction. Traditional treatments, including antibiotic therapy, surgical debridement, and bone grafting, often fail to address these defects effectively. However, recent advancements in biomaterials research have introduced innovative solutions for managing infectious bone defects.

Objective: Early diagnosis and treatment of candidemia in intensive care units (ICUs) remain a significant challenge globally because of the lack of well-established non-culture-based diagnostic methods. This study aimed to evaluate risk factors in critically ill ICU patients, develop a unique score, and create a real-time polymerase chain reaction (PCR) assay for the early diagnosis of candidemia.
Materials And Methods: The study was conducted in three phases: 1) Retrospective analysis of 100 ICU patients from İstanbul University-Cerrahpaşa between January 2017 and December 2018 to identify risk factors for invasive candidiasis, 2) development of Cerrahpaşa score based on these findings, and 3) prospective evaluation of 75 ICU patients, applying the newly created Cerrahpaşa score and implementing a rapid PCR-based test on whole blood samples.
