Objectives:  This article investigates the changes in blood-based biomarkers associated with mild cognitive impairment (MCI) risk in type 2 diabetic patients following local antibiotic periodontal treatment.

Materials And Methods:  A secondary analysis of data from a 24-week randomized controlled trial was conducted, involving 27 patients with type 2 diabetes mellitus and periodontitis. Participants received periodontal treatment biweekly from baseline until the 6th week of the study. Sixteen patients were assigned to an intervention group and received local antibiotic periodontal treatment (Periofol 2%). The outcomes were periodontal inflammation score, which was measured using periodontal inflamed surface area, the inflammation markers levels (tumor necrosis factor-α, C-reactive protein, and interleukin [IL]-6), and MCI risk score, which was assessed using protein plasma analysis through blood test. The evaluations were performed at baseline and week 24th in both groups. The changes in periodontal inflammation scores, inflammation parameters, and MCI risk in baseline and week 24th were analyzed.

Statistical Analysis:  The Wilcoxon signed-rank test was used for within-group analysis and the Mann-Whitney test was utilized for between-group analysis.

Results:  Periodontal parameters were improved in both groups ( < 0.05). IL-6, complement C3, and alpha-2-antiplasmin levels were significantly decreased in the intervention group ( < 0.05). In between-group comparisons, there was a significant difference between the control and intervention groups in apolipoprotein A1, apolipoprotein C1, and alpha-1-B glycoprotein levels in week 24th ( < 0.05).

Conclusion:  Even though the periodontal status showed significant improvement after being given local antibiotic periodontal treatment, the changes in MCI risk proteins plasma remained unclear.

Streptococcus pneumoniae (SP) remains an important cause of community acquired pneumonia (CAP). We aimed to describe the prevalence and characteristics of outpatients with radiologically confirmed pneumococcal CAP. Between November 2017 and December 2019, a French network of general practitioners enrolled CAP-suspected adults, with ≥1 clinical signs of infection and ≥1 signs of pulmonary localization in an observational study.

Antibiotic resistance genes (ARGs) are markers of drug-resistant pathogens, monitoring them contributes to prevent resistance to drugs. The detection methods for ARGs including PCR and isothermal amplification are sensitive and selective. However, it may take several hours or cannot be used on spot.

Objectives: Urinary tract infections (UTIs) are an important cause of empiric antibiotic (over)treatment at the emergency department (ED). To enhance empiric antibiotic choices, mapping the national and local microbiology and antimicrobial resistance (AMR) patterns is crucial. This study aims to examine resistance patterns at a Brussels ED and to identify risk factors for AMR to evaluate current treatment guidelines and help combat AMR.
