  The Division of Vectors and Parasitic Diseases of the Korea Disease Control and Prevention Agency conducted a surveillance project at 11 locations from late March to October 2023 to monitor the abundance of Culex tritaeniorhynchus, a vector of Japanese encephalitis (JE). Considering the period of appearance, the southern region was monitored from March (13th week). A total of 221,311 females, comprising seven genera and 17 species, were collected. Of these, 43,251 C. tritaeniorhynchus were collected, representing an increase of 6.3% from the previous year (40,679). Higher densities were recorded from July to September, with higher numbers collected in the southern region than in the northern region. C. tritaeniorhynchus was first collected on March 22, 2023, from Busan Metropolitan City and Jeju Province, which led to a warning of precautions against JE. On July 26, 2023, an alert was issued because more than 50% of the mosquitoes collected in Busan Metropolitan City were C. tritaeniorhynchus (91.4%). Due to climate change, the period for the occurrence of mosquitos has quickened, and the pattern of mosquito prevalence is also changing; therefore, continuous monitoring is necessary.

  The Korea Disease Control and Prevention Agency established Global Antimicrobial Resistance Surveillance System in Korea (Kor-GLASS), an antimicrobial resistance (AMR) surveillance system compatible with the Global Antimicrobial Resistance Surveillance System (GLASS). This study aimed to analyze the AMR status of major pathogens collected during the operation of the 2nd Kor-GLASS from 2020 to 2022. Among 549,686 target cultures, 41,857 pathogens were identified. The predominant bacterial species were Escherichia coli (n=30,314), Klebsiella pneumoniae (n=3,259), and Staphylococcus aureus (n=2,241). The resistance rate of methicillin-resistant S. aureus decreased from 53.5% in 2016 to 45.7% in 2022. The resistance rate to vancomycin of Enterococcus faecium increased from 29.9% in 2016 to 40.9% in 2019, and then slightly decreased to 35.1% in 2022. Among the blood isolates of Enterobacterales resistant to carbapenem used to treat multidrug-resistant bacteria, E. coli and Salmonella spp. maintained a resistance rate of less than 0.2%, whereas the rate for K. pneumoniae steadily increased from 2.1% (2016) to 4.0% (2020), 6.8% (2021), and 6.7% (2022). Kor-GLASS generates standardized AMR data based on a collection of strains and clinical information related to the bacterial isolates. The results of this study provide basic data for the development of policies for antimicrobial resistance control.

  The prevalence of low handgrip strength and sarcopenia in people aged ≥65, in the Republic of Korea, was investigated using data from the Korea National Health and Nutrition Examination Survey (KNHANES). This study included participants in the 2022 KNHANES aged ≥65 years who had handgrip strength and muscle mass measured by bioelectrical impedance analysis, according to the Asian Working Group for Sarcopenia 2019 guidelines. In 2022, prevalence of low handgrip strength among those aged ≥65 was 14.2% for men and 18.8% for women, and the prevalence of sarcopenia was 6.6% for men and 9.2% for women. In this study, the prevalence of sarcopenia was higher in older age, women than in men, and low-income groups. In conclusion, older people and those with in low-income groups are vulnerable to sarcopenia; therefore, it is necessary to focus on early identification of sarcopenia and development of prevention and management intervention programs for these people.
