Guideline for management of septic arthritis in native joints (SANJO).
This clinical guideline is intended for use by orthopedic surgeons and physicians who care for patients with possible or documented septic arthritis of a native joint (SANJO). It includes evidence and opinion-based recommendations for the diagnosis and management of patients with SANJO
Nationwide, population-based observational study of the molecular epidemiology and temporal trend of carbapenemase-producing Enterobacterales in Norway, 2015 to 2021
National and regional carbapenemaseproducing Enterobacterales (CPE) surveillance is
essential to understand the burden of antimicrobial
resistance, elucidate outbreaks, and develop infection-control or antimicrobial-treatment recommendations. Aim: This study aimed to describe CPE and their
epidemiology in Norway from 2015 to 2021. Methods:
A nationwide, population-based observational study
of all verified clinical and carriage CPE isolates submitted to the national reference laboratory was conducted. Isolates were characterised by antimicrobial
susceptibility testing, whole genome sequencing
(WGS) and basic metadata. Annual CPE incidences
were also estimated. Results: A total of 389 CPE isolates were identified from 332 patients of 63years
median age (range:0–98). These corresponded to
341 cases, 184 (54%) being male. Between 2015 and
2021, the annual incidence of CPE cases increased
from 0.6 to 1.1per 100,000person-years. For CPEisolates with available data on colonisation/infection,
58% (226/389)were associated with colonisation and
38% (149/389) with clinical infections. WGS revealed
a predominance of OXA-48-like (51%; 198/389) and
NDM (34%; 134/389) carbapenemases in a diversified
population of Escherichia coli and Klebsiella pneumoniae, including high-risk clones also detected globally.
Most CPE isolates were travel-related (63%;245/389).
Although local outbreaks and healthcare-associated
transmission occurred, no interregional spread was
detected. Nevertheless, 18% (70/389) of isolates not
directly related to import points towards potentially
unidentified transmission routes. A decline in travelassociated cases was observed during the COVID-19
pandemic. Conclusions: The close-to-doubling of CPE
case incidence between 2015 and 2021 was associated
with foreign travel and genomic diversity. To limit further transmission and outbreaks, continued screening
and monitoring is essential
Impact of extensive antibiotic treatment on faecal carriage of antibiotic-resistant enterobacteria in children in a low resistance prevalence setting
We prospectively studied the consequences of extensive antibiotic treatment on faecal carriage of antibiotic-resistant enterobacteria in a cohort of children with cystic fibrosis (CF) and a cohort of children with cancer compared to healthy children with no or low antibiotic exposure. The study was conducted in Norway in a low resistance prevalence setting. Sixty longitudinally collected faecal samples from children with CF (n = 32), 88 samples from children with cancer (n = 45) and 127 samples from healthy children (n = 70) were examined. A direct MIC-gradient strip method was used to detect resistant Enterobacteriaceae by applying Etest strips directly onto agar-plates swabbed with faecal samples. Whole genome sequencing (WGS) data were analysed to identify resistance mechanisms in 28 multidrug-resistant Escherichia coli isolates. The prevalence of resistance to third-generation cephalosporins, gentamicin and ciprofloxacin was low in all the study groups. At inclusion the prevalence of ampicillin-resistant E. coli and trimethoprim-sulfamethoxazole-resistant E. coli in the CF group compared to healthy controls was 58.6% vs. 28.4% (p = 0.005) and 48.3% vs. 14.9% (p = 0.001), respectively, with a similar prevalence at the end of the study. The prevalence of resistant enterobacteria was not significantly different in the children with cancer compared to the healthy children, not even at the end of the study when the children with cancer had been treated with repeated courses of broad-spectrum antibiotics. Children with cancer were mainly treated with intravenous antibiotics, while the CF group mainly received peroral treatment. Our observations indicate that the mode of administration of antibiotics and the general level of antimicrobial resistance in the community may have an impact on emergence of resistance in intestinal enterobacteria during antibiotic treatment. The WGS analyses detected acquired resistance genes and/or chromosomal mutations that explained the observed phenotypic resistance in all 28 multidrug-resistant E. coli isolates examined

<p>(A) Median (range, shown inside the columns) number of days per calendar year with antibiotic treatment in the study period among patients who received at least one course of treatment. For some antibiotics, median number of days is not shown (NS) due to no or only one or two patients treated. (B) Number of patients (%) in each patient group treated with at least one course of the antibiotic. For one of the 32 CF patients and for one of the 45 cancer patients included in the study no antibiotic treatment was registered since a faecal sample was provided only at the time of inclusion into the study. ^Amoxicillin was only administered orally and ampicillin was only administered intravenously. *Prophylactic treatment given to cancer patients is not included.</p
