Microbial resistance due to antibiotic misuse is a worldwide problem. This study aimed to examine the trends in antibiotic prescription after tooth extraction in Korea.

From the database of National Health Insurance Sharing Service, patients who underwent tooth extraction from 2002 to 2018 were selected as subjects, and 10% of them were selected via stratified sampling based on sex and age. Overall, 15,838,529 cases were observed for annual antibiotic prescription and broad-spectrum antibiotic prescription patterns. Additionally, standardized annual antibiotic use was calculated using a defined daily dose.

Prescriptions were issued in 13,429,770 (84.8%) of the tooth extraction cases, of which 12,179,185 (90.7%) included antibiotics. Logistic regression analysis revealed that the likelihood of prescribing antibiotics after tooth extraction decreased in 2003 compared to 2002 (odds ratio, 0.95) but increased from 2004 to 2018. In the case of the broad-spectrum antibiotic prescription rate, there was no clear trend between 2002 and 2012 (odds ratio, 0.89-1.07); however, over the last 5 years, the likelihood of broad-spectrum antibiotic prescription has steadily increased. The value of antibiotics based on the defined daily dose of 1000 patients per day was calculated to be 4.39 in 2002, exhibiting a steady increase later and reaching 6.97 in 2018, whereas that of broad-spectrum antibiotics was 1.68 in 2002 and has since been on the rise; the highest was 3.82 in 2018.

Antibiotic use after tooth extraction increased over the last 17 years; additionally, the rate of prescribing broad-spectrum antibiotics has increased over the last 5 years.

The intent was to analyse the association of periodontitis with the development of rheumatoid arthritis (RA) using a representative population-based cohort and longitudinal matched-cohort design.

Participants were 40 years of age or older and had not been diagnosed with RA between 2002 and 2006. Among the participants, those who were newly diagnosed with periodontitis between 2004 and 2006 (excluding cases that had already been diagnosed with periodontitis between 2002 and 2003) were allotted to the periodontitis group. https://www.selleckchem.com/products/a-1210477.html Among the participants, those who had never been diagnosed with periodontitis between 2002 and 2006 formed the control group, matched by sex, age, and household income at a 11 ratio. From 2007 to 2018, the 2 groups (n = 691,506) were followed to monitor the development of RA. The t-test and χ
test compared the general characteristics and health-related variables of both groups. The Kaplan-Meier method with a log-rank test was conducted to compare the incidence of RA in both groups. The hazard ratio (HR) and adjusted hazard ratio (aHR) were calculated using a Cox proportional hazard regression analysis to evaluate the risk of subsequent RA.

Univariate analysis revealed that the periodontitis group was more likely to develop RA than the control group (hazard ratio 1.10), and multivariate analysis also revealed a higher incidence risk of RA (adjusted hazard ratio 1.09) in the periodontitis group.

Our findings demonstrate that periodontitis is associated with an increased risk of developing RA.

A total of 56 patients on metformin and gliclazide were separated into two groups Group 1 did not receive empagliflozin (EMPA-) and the Group 2 received 10 mg/day of empagliflozin for 6 months (EMPA+). The expressions of T-bet, ROR-γt, FOXP3, STAT1/3/5 and SOCS1/3 were evaluated in CD4+ T cells with real-time PCR. The production of IFN-γ, IL-17, and IL-10 from CD4+ T cells was measured using ELISA. The proliferation of Th cells was assessed with flow cytometry. Six months of empagliflozin therapy significantly reduced the expression of ROR-γt and increased FOXP3 and STAT5 expression, compared to baseline. Production of IL-17 decreased after empagliflozin treatment, while IL-10 was enhanced in the EMPA+ group. Oral administration of empagliflozin or the addition of empagliflozin to the cell cultures diminished the proliferation of Th cells. Empagliflozin showed anti-inflammatory effects on Th cells by decreasing Th17-related factors, reducing proliferation capacity, and increasing Treg cell properties.
Clinical practice guidelines recommend performing head CT and skull radiographs (SR) when evaluating infants for physical abuse. We compared the accuracy of 3-dimensional CT (3DCT) and SR for detecting skull fractures.

We reviewed children <12 months evaluated for physical abuse undergoing 3DCT and SR between January 2017 and December 2018. 3DCT and SR images were blindly read by 2 radiologists. Interrater reliability (IRR) was calculated. Diagnostic accuracy was compared using McNemar's test.

158 infants with a mean age of 5.0 months underwent 3DCT and SR. Consensus reading identified 46 fractures (29.1%) on 3DCT and 40 fractures (25.3%) on SR. IRR was higher for 3DCT (κ=0.95) than for SR (=0.65). 11 fractures were identified on 3DCT but not SR. 5 fractures were identified on SR but not 3DCT. There was no difference in the diagnostic accuracy of 3DCT and SR (χ
=1.56, p=0.211).

We found no difference in the accuracy of 3DCT and SR for detecting skull fractures in infants. Because 3DCT has better IRR and evaluates for both bony and intracranial injuries it is superior to SR. Omitting SRs may be acceptable if a 3DCT is performed, and would reduce radiation exposure without compromising diagnostic accuracy.
