OBJECTIVES
Aggressive driving behavior is a significant predictor of traffic accidents. In particular, the driving behavior of taxi drivers is a critical issue that can impact the safety of both drivers and passengers. This study explored the sleep, cognitive, and psychological factors associated with taxi drivers’ aggressive driving behavior.
METHODS
In this descriptive study, a self-report questionnaire was distributed to taxi drivers in Seoul and Gyeonggi Province from August 22, 2022 to December 30, 2022. In all, 992 respondents were analyzed using negative binomial regression.
RESULTS
The mean score for aggressive driving behavior among taxi drivers was 13.76±11.47, with sub-scores of 3.46±3.48 for lapse, 3.31±3.16 for error, and 6.99±5.76 for violation. Contributing factors included sleep disorders, cognitive decline, and psychological factors. A higher score for aggressive driving behavior was associated with an increased severity of insomnia and daytime sleepiness, higher rates of cognitive failure, and elevated levels of depression and stress.
CONCLUSIONS
Our findings highlight the importance of addressing the sleep, cognitive, and psychological factors associated with aggressive driving behaviors among taxi drivers. Further study is needed to evaluate the causal relationship. In addition, it is imperative to develop educational programs and interventions to manage these issues effectively.; Summary

Korean summary
택시 기사의 안전운전 행동은 교통사고, 운전자와 승객의 안전과 연결된 이슈이다. 기존 연구에서 택시 기사의 가파른 고령화와 열악한 직업 환경 등이 과격한 운전행위의 영향요인으로 보고하고 있다. 이 연구에서 택시기사의 수면, 인지기능 및 심리적인 요인도 과격한 운전행위와 관련이 있음으로 보여주고 있다.

Key Message
It is important to predict taxi drivers’ aggressive driving behavior to decrease the traffic accidents that result from such be- havior. Previous studies have shown that general and occupational characteristics have a significant impact on aggressive driving behavior, whereas research on the psychological factors is limited. Our comprehensive investigation of the psycho- logical factors as well as the sleep factors and cognitive functions of taxi drivers (as part of a rapidly aging population) showed a significant relationship between these factors and aggressive driving behavior.

Abstract

OBJECTIVES
We estimated the population prevalence of antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), including unreported infections, through a Korea Seroprevalence Study of Monitoring of SARS-CoV-2 Antibody Retention and Transmission (K-SEROSMART) in 258 communities throughout Korea.

METHODS

In August 2022, a survey was conducted among 10,000 household members aged 5 years and older, in households selected through two stage probability random sampling. During face-to-face household interviews, participants self-reported their health status, COVID-19 diagnosis and vaccination history, and general characteristics. Subsequently, participants visited a community health center or medical clinic for blood sampling. Blood samples were analyzed for the presence of antibodies to spike proteins (anti-S) and antibodies to nucleocapsid proteins (anti-N) SARS-CoV-2 proteins using an electrochemiluminescence immunoassay. To estimate the population prevalence, the PROC SURVEYMEANS statistical procedure was employed, with weighting to reflect demographic data from July 2022.

RESULTS

In total, 9,945 individuals from 5,041 households were surveyed across 258 communities, representing all basic local governments in Korea. The overall population-adjusted prevalence rates of anti-S and anti-N were 97.6% and 57.1%, respectively. Since the Korea Disease Control and Prevention Agency has reported a cumulative incidence of confirmed cases of 37.8% through July 31, 2022, the proportion of unreported infections among all COVID-19 infection was suggested to be 33.9%.

CONCLUSIONS

The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19, confirming that most individuals possess antibodies to SARS-CoV-2 and that a significant number of unreported cases existed. Furthermore, this study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

Key Message
The K-SEROSMART represents the first nationwide, community-based seroepidemiologic survey of COVID-19. In August 2022, most of the Korean people had antibodies to COVID-19, and one in three people was estimated to have an unreported infection. This study lays the foundation for a surveillance system to continuously monitor transmission at the community level and the response to COVID-19.

Abstract

OBJECTIVES
This study investigated whether Janus kinase inhibitors (JAKis) raise the risk of cardiovascular disease (CVD), venous thromboembolism (VTE), and cancer in patients with rheumatoid arthritis (RA).

METHODS

We conducted a real-world retrospective observational study using data obtained from the Korean National Health Insurance Service database. Two data sets were analyzed: tumor necrosis factor inhibitor (TNFi)/JAKi-naive RA patients (set 1) and all RA patients who used TNFis or JAKis (set 2). The incidence rate ratios (IRRs) and hazard ratios (HRs) for acute myocardial infarction (AMI), stroke, cardiovascular (CV)-related mortality, major adverse cardiovascular events (MACE), VTE, arterial thromboembolism (ATE), cancer, and all-cause mortality were compared between the JAKi and TNFi groups.

RESULTS

Set 1 included 1,596 RA patients (JAKi group: 645; TNFi group: 951), and set 2 included 11,765 RA patients (JAKi group: 2,498; TNFi group: 9,267). No adverse events (AEs) showed significantly higher IRRs in the JAKi groups than in the TNFi groups of sets 1 and 2. The HRs for MACE in the JAKi groups of sets 1 and 2 were 0.59 (95% confidence [CI], 0.35 to 0.99) and 0.80 (95% CI, 0.67 to 0.97), respectively. The JAKi group of set 2 showed a significantly higher risk of all-cause mortality (HR, 1.71; 95% CI, 1.32 to 2.20), but the other AEs did not demonstrate increased risks in the JAKi groups.

CONCLUSIONS

In this study, JAKis did not increase the risk of AMI, stroke, CV-related mortality, MACE, VTE, ATE, or cancer in Korean RA patients relative to TNFis.

Summary

Korean summary
1. 한국인 류마티스관절염 환자를 대상으로 한 실제임상자료 결과, JAK 억제제가 종양괴사인자 억제제에 비해 심혈관질환, 혈전증, 암 등의 심각한 부작용을 증가시키지는 않았다. 2. 본 연구를 토대로 한국인 대상자에서 JAK 억제제가 심혈관질환 등의 심각한 부작용을 증가시키는지에 대한 재평가가 필요하다.

Key Message
1. The real word-data based results showed that risks of MACE, thromboembolism, and cancers were not increased in Korean RA patients with JAK inhibitor when compared to Korean RA patients with TNF inhibitors. 2. Therefore, the risk of serious adverse events of JAK inhibitors in Korean population should be reconsidered and reassessed before adding black box warning of JAK inhibitors.

Abstract

OBJECTIVES
Although an association is known to exist between metabolic syndrome (MetS) and heart failure (HF) risk, large longitudinal studies are limited. We investigated metabolic status as a risk factor for HF in middle-aged male and female and considered sex differences in various risk factors for HF using nationwide real-world data.

METHODS

Data obtained from the Korean National Health Insurance Service from 2009 to 2016 were analyzed. A total of 2,151,597 middle-aged subjects (between 50 and 59 years old) were enrolled. Subjects were divided into 3 groups (normal, pre‐ MetS, and MetS). Cox proportional hazard models were used to estimate the association between MetS and incident HF after adjusting for clinical risk factors.

RESULTS

At baseline, MetS existed in 23.77% of male and 10.58% of female. Pre-MetS and MetS increased the risk of HF: the hazard ratios of pre-MetS for incident HF were 1.508 (95% confidence interval [CI], 1.287 to 1.767) in male and 1.395 (95% CI, 1.158 to 1.681) in female, and those of MetS were 1.711 (95% CI, 1.433 to 2.044) in male and 2.144 (95% CI, 1.674 to 2.747) in female. Current smoking, a low hemoglobin level, underweight (body mass index < 18.5 kg/m2), a high creatinine level, and acute myocardial infarction were also predictors of HF in both sexes.

CONCLUSIONS

Pre-MetS and MetS were identified as risk factors for HF in middle-aged male and female. The effect of MetS on the occurrence of HF was stronger in female than in male. Pre-MetS was also a predictor of HF, but was associated with a lower risk than MetS.

OBJECTIVES
Since Korea has been known to be one of the endemic area for hepatitis B virus(HBV) infection, vaccination for HBV has been recommended for all neonates in Korea. After starting vaccination in 1983, the change of sero-positivity of HBsAg and HBsAb is expected. This study was carried out to investigate the seropositive rate of hepatitis B virus surface antigen and antibody in high school freshmen students in Chungju-city.
METHODS
AND MATERIALS: From 1998 to 2001, a total of 11,735 who were born in 1982 to 1986, were enrolled in this study. HBsAg and anti-HBs were tested by reversed passive hemagglutination and passive hemagglutination, respectively. PESULTS: The study population was 11,735 students who were composed of 5,813 males (49.6%) and 5,914 females (50.4%). The HBsAg sero-positivity of male and female students was 3.25% (n=381) and 2.59% (n=153) respectively. The anti-HBs sero-positivity of male and female students was 62.2% (n=3,154) and 64.1% (n=2,969) respectively. There are significant difference observed in comparison of HBsAg and anti-HBs seropositivity according to sex (p<0.05). From 1982 to 1986 on birth year, anti-HBs sero-positivity has been increased significantly from 63.3% to 73.3%. But the change of HBsAg sero-positivity has not been changed significantly.
CONCLUSIONS
As compared with previous studies of HBsAg and anti-HBs, the sero-positive rate of HBsAg has not been changed but that of HBsAb has been increased significantly. This result revealed that the effect of HBV vaccination program was successful.; Summary
