Article Abstract
Background: This study aimed to document the epidemiology of revision total knee arthroplasty following periprosthetic joint infection (RTKA-f-PJI) in Korea between 2011 and 2019 and analyze the economic burden of RTKA-f-PJI.
Methods: Epidemiological data on RTKA-f-PJI in Korea between 2011 and 2019 were obtained from the Korean Health Insurance Review and Assessment database. The annual numbers and growth rates of entire RTKAs and RTKA-f-PJIs and the RTKA-f-PJI rate (RTKA-f-PJI / entire RTKAs) were determined. Subgroup analyses were performed according to sex and age. TKA failure was categorized into early and late failures, and RTKA-f-PJI rates were compared between the groups. The total and mean personal costs for each year were compared between the RTKA-f-PJI and RTKA-f-non-PJI groups.
Results: Between 2011 and 2019, the total growth rate of RTKA-f-PJI was 57.6%, and the RTKA-f-PJI rate was maintained at approximately 30%. The RTKA-f-PJI rate was higher in males than in females. The number of RTKA-f-PJIs markedly increased in patients aged 70-79 years and ≥ 80 years. The RTKA-f-PJI rates for early and late failures were 45% and 24.8%, respectively. The total cost of RTKA-f-PJI increased from $15,757,308 in 2011 to $19,606,594 in 2019. The mean personal cost of RTKA-f-PJI was more than 4 times higher than that of RTKA-f-non-PJI.
Conclusions: The number and socioeconomic costs of RTKA-f-PJIs increased significantly in Korea between 2011 and 2019. Given that RTKA-f-PJI is a complex procedure associated with higher complication rates and unsatisfactory functional outcomes, continuous efforts to reduce the incidence of PJI after TKA are necessary.

Background: To investigate the genetic diversity, evolutionary dynamics, and phylogeography of DENV strains circulating in Saudi Arabia.
Methods: We conducted serotyping, whole-genome sequencing, and phylogeographic analyses of DENV strains collected across Saudi Arabia between 2021 and 2023. A total of 20 full genomes were successfully obtained: DENV-1 (n = 2), DENV-2 (n = 10), and DENV-3 (n = 8).
Applying the "positive predictive value-recall diagram" to monitor performance and provide recommendations for screening radiologists.

Dutch Expert Centre for Screening (LRCB), Nijmegen, The Netherlands.
Objectives: To evaluate the suitability of "positive predictive value-recall" (PPV-recall) diagrams for monitoring performance and providing recommendations for groups of radiologists (RUs or reading units) in breast cancer screening.
Materials And Methods: This retrospective study used datasets from triennial quality assurance audits within the Dutch screening programme. The recall rate (RR), cancer detection rate (CDR), and PPV between 2010 and 2019 were plotted in PPV-recall diagrams separately for initial and subsequent screening.

Background: Growing concern surrounds the risk of neurodegenerative diseases in high-level collision sports, but research on Rugby Union's connection to these diseases is limited.
Objective: This study sought to examine the long-term neurodegenerative disease risk associated with participation in high-level Rugby Union ('rugby'), utilising whole-population administrative records.
Methods: This retrospective cohort study in New Zealand compared males born between 1920 and 1984 who were active in high-level (provincial or higher) rugby between 1950 and 2000 (n = 12,861) with males from the general population (n = 2,394,300), matched by age, ethnicity, and birthplace.
The Occurrence of Obstructive Sleep Apnea and Its Association With Alzheimer Dementia in Medicaid-Enrolled Adults With Down Syndrome, 2011-2019.

Down syndrome is a condition caused by trisomy of chromosome 21 and is the most common genetic cause of intellectual disability. Due to distinct body and facial morphology, people with Down syndrome appear to be at increased risk for obstructive sleep apnea (OSA). Additionally, adults with Down syndrome are at increased risk for Alzheimer dementia at younger ages than the general population, and OSA has been identified as a risk factor for Alzheimer dementia in the general population.

Background And Aims: The first international guideline for managing preneoplastic conditions of the stomach (MAPS I) was published in 2012, followed by an update (MAPS II) in 2019. As adherence to these guidelines remains uncertain, we evaluated adherence by comparing the management of preneoplastic gastric conditions before and after the introduction of MAPS I and II in selected European centers.
Methods: Patients data were retrieved from nine endoscopy units in seven European countries during three periods: pre-MAPS I (2010/2011), post-MAPS I (2017/2018), and post-MAPS II (2022/2023).
