21 (1.13-1.29), 1.26 (1.15-1.37), and 1.54 (1.40-1.68), respectively, compared with those with normal vision. The corresponding HRs (95% CIs) for injury-related mortality were 1.12 (0.96-1.32), 0.98 (0.76-1.26), and 1.36 (1.04-1.79), respectively, and the corresponding HRs (95% CIs) for cardiovascular mortality were 1.32 (1.12-1.57), 1.43 (1.15-1.77), and 2.41 (1.94-2.99).

In this large cohort of young and middle-aged individuals, VI was associated with increased risk of mortality especially due to cardiovascular disease.

Correct determination of penicillin susceptibility is pivotal for using penicillin in the treatment of Staphylococcus aureus infections. This study examines the performance of MIC determination, disc diffusion and a range of confirmatory tests for detection of penicillin susceptibility in S. aureus.

A total of 286 consecutive penicillin-susceptible S. aureus blood culture isolates as well as a challenge set of 62 MSSA isolates were investigated for the presence of the blaZ gene by PCR and subjected to penicillin-susceptibility testing using broth microdilution MIC determination, disc diffusion including reading of the zone edge, two nitrocefin tests and the cloverleaf test.

Using PCR-based detection of blaZ as the gold standard, both broth microdilution MIC testing and disc diffusion testing resulted in a relatively low accuracy (82%-93%) with a sensitivity ranging from 49%-93%. Among the confirmatory tests, the cloverleaf test performed with 100% accuracy, while zone edge interpretation and nitrocefin-r confirmation of a presumptive β-lactamase-negative isolate.

Infections with carbapenem-resistant Enterobacterales (CRE) are an emerging problem in pets and a major threat to public health. We determined the genetic relationships among carbapenemase-producing Klebsiella pneumoniae (CPKp) strains causing infections in hospitalized pets in a veterinary clinic and those found in the environment.

WGS was performed with both the Illumina and Nanopore platforms. Searches of genetic features were performed using several databases and bioinformatics tools, and phylogeny was assessed by whole-genome MLST (wgMLST) using SeqSphere and SNP calling with Snippy.

WGS analysis of the CPKp strains identified all environmental and almost all animal strains as the high-risk clone ST11, with the exception of two strains that belonged to ST307. All CPKp belonged to novel complex types (CTs) and carried a conjugative 63 kb IncL plasmid encoding the carbapenemase gene blaOXA-48, yersiniabactin and other virulence factors. Although all CPKp ST11 strains carried additional similar IncR plasmids harbouring multiple antimicrobial resistance genes (ARGs), such as the plasmid-mediated blaDHA-1 AmpC gene, some structural variations were observed. The two ST307 strains carried identical 156 kb MDR IncFIB(K) plasmids with several ARGs, including the blaCTX-M-15 ESBL gene. Both wgMLST and cgSNP analysis confirmed that CPKp strains of the same ST were genetically highly related independent of the source of isolation.

This study demonstrated that the clinical CPKp strains were highly related to those contaminating the clinical environment. These findings confirmed nosocomial spread and highlight veterinary hospitals as a source of CPKp, which may further spread to animals, the environment and humans.

Complicated intra-abdominal infections (cIAIs) are associated with significant morbidity and mortality. The aim of this study was to describe the clinical characteristics of patients with cIAI in a multicentre study and to develop clinical prediction models (CPMs) to help identify patients at risk of mortality or relapse.

A multicentre observational study was conducted from August 2016 to February 2017 in the UK. Adult patients diagnosed with cIAI were included. Multivariable logistic regression was performed to develop CPMs for mortality and cIAI relapse. The c-statistic was used to test model discrimination. Model calibration was tested using calibration slopes and calibration in the large (CITL). The CPMs were then presented as point scoring systems and validated further.

Overall, 417 patients from 31 surgical centres were included in the analysis. At 90days after diagnosis, 17.3 per cent had a cIAI relapse and the mortality rate was 11.3 per cent. Predictors in the mortality model were age, cIAI aet treatment, these now require external validation.

Although the characterization of cell-free extrachromosomal circular DNA (eccDNA) has gained much research interest, the methylation status of these molecules is yet to be elucidated. We set out to compare the methylation densities of plasma eccDNA of maternal and fetal origins, and between small and large molecules. The clearance of fetal eccDNA from maternal circulation was also investigated.

We developed a sequencing protocol for eccDNA methylation analysis using tagmentation and enzymatic conversion approaches. A restriction enzyme-based approach was applied to verify the tagmentation results. The efficiency of cell-free fetal eccDNA clearance was investigated by fetal eccDNA fraction evaluations at various postpartum time points.

The methylation densities of fetal eccDNA (median 56.3%; range 40.5-67.6%) were lower than the maternal eccDNA (median 66.7%; range 56.5-75.7%) (P = 0.02, paired t-test). Futibatinib nmr In addition, eccDNA molecules from the smaller peak cluster (180-230 bp) were of lower methylation levels than those from the larger peak cluster (300-450 bp). Both of these findings were confirmed using the restriction enzyme approach. We also observed comparable methylation densities between linear and eccDNA of both maternal and fetal origins. The average half-lives of fetal linear and eccDNA in the maternal blood were 30.2 and 29.7 min, respectively.

We found that fetal eccDNA in plasma was relatively hypomethylated compared to the maternal eccDNA. The methylation densities of eccDNA were positively correlated with their sizes. In addition, fetal eccDNA was found to be rapidly cleared from the maternal blood after delivery, similar to fetal linear DNA.
