Purpose: Adolescence involves parental health management, with parents or guardians often making decisions regarding vaccination. This study assessed how parents’ knowledge, attitudes, and health beliefs about influenza vaccination influenced their intentions to vaccinate their adolescent children. Methods: This descriptive survey was approved by the Institutional Review Board of Kyung Hee University for use between December 1 and 31, 2022. Parents of adolescents aged 13–19 years were surveyed face-to-face and online using a modified tool to evaluate their vaccination intentions, knowledge, attitudes, and health beliefs regarding their children’s influenza vaccination. The analysis included 149 responses and involved methods such as calculating means, standard deviations, t-tests, analyses of variance, Scheffe tests, correlations, and hierarchical regressions. Results: On a 7-point scale, the mean score for parental intention to vaccinate their adolescents was 4.99±1.24. Hierarchical regression analysis revealed that positive attitudes towards influenza vaccination, television and radio information, and perceived benefits influenced children’s vaccination intentions, with positive parental attitudes being the most significant factor. The independent variables accounted for 66.7% of the variance in vaccination intentions. Conclusion To improve parental intentions to vaccinate adolescent children against influenza, promoting vaccination benefits and safety through the media is crucial to enhance favorable attitudes. Initiatives that strengthen positive parental attitudes towards influenza vaccination and increase awareness of its benefits can effectively boost vaccination intentions.

Background and Objectives: Outcomes of deferring percutaneous coronary intervention (PCI) without invasive physiologic assessment for intermediate coronary lesions is uncertain.We sought to compare long-term outcomes between medical treatment and PCI of intermediate lesions without invasive physiologic assessment. Methods: A total of 899 patients with intermediate coronary lesions between 50% and 70% diameter-stenosis were randomized to the conservative group (n=449) or the aggressive group (n=450). For intermediate lesions, PCI was performed in the aggressive group, but was deferred in the conservative group. The primary endpoint was major adverse cardiac events (MACE, a composite of all-cause death, myocardial infarction [MI], or ischemia-driven any revascularization) at 3 years. Results: The number of treated lesions per patient was 0.8±0.9 in the conservative group and 1.7±0.9 in the aggressive group (p=0.001). At 3 years, the conservative group had a significantly higher incidence of MACE than the aggressive group (13.8% vs. 9.3%; hazard ratio [HR], 1.49; 95% confidence interval [CI], 1.00–2.21; p=0.049), mainly driven by revascularization of target intermediate lesion (6.5% vs. 1.1%; HR, 5.69; 95% CI, 2.20–14.73;p<0.001). Between 1 and 3 years after the index procedure, compared to the aggressive group, the conservative group had significantly higher incidence of cardiac death or MI (3.2% vs.0.7%; HR, 4.34; 95% CI, 1.24–15.22; p=0.022) and ischemia-driven any revascularization. Conclusions For intermediate lesions, medical therapy alone, guided only by angiography, was associated with a higher risk of MACE at 3 years compared with performing PCI, mainly due to increased revascularization.

BACKGROUND/OBJECTIVES: Green Citrus junos (yuja) peel extract has higher naringin and hesperidin contents and antioxidant activity than yellow yuja peel extract, but its anti-obesity effects are unclear. This study examined the anti-obesity properties of green yuja peel ethanol extract (GYE) in 3T3-L1 cells and high-fat diet (HFD)-induced obese mice.MATERIALS/METHODS: The effects of GYE on adipocyte differentiation were assessed by measuring Oil red O staining, mRNA and protein expression. The beneficial effects of GYE on HFD-induced obese mice were evaluated using the body weight, body composition, visceral fat size, and biochemical analysis. RESULTS: GYE inhibited adipocyte differentiation and lipid accumulation compared to the control cells, as evidenced by Oil red O staining and the triglyceride level, respectively.GYE down-regulated the adipogenic genes CCAAT/enhancer binding protein α (C/EBPα) and peroxisome proliferator-activated receptor γ (PPARγ), and lipogenic gene diacylglycerol O-acyltransferase 2 (DGAT2). GYE at 100 μg/mL downregulated the phosphorylation levels of phosphoinositide 3-kinase (PI3K) and protein kinase B (Akt), and their downstream targets PPARγ and sterol regulatory element-binding protein-1 (SREBP-1c) compared to the control group. In obese mice, GYE (100 mg/kg/day) reduced the body weight, body weight gain, and serum lipid level compared to the control group. Analysis using dual-energy X-ray absorptiometry showed that GYE decreased the fat percentage, fat in tissue, and abdominal circumference, while it increased the lean percentage compared to control group.Furthermore, GYE significantly reduced the visceral fat weight and size compared to the control group. CONCLUSION GYE suppressed adipocyte differentiation by inhibiting the PI3K-Akt pathway in vitro and reduced the body fat mass and visceral adiposity in HFD-induced obese mice.These findings suggest that GYE is a viable natural option for combating obesity.

Purpose: Adolescence involves parental health management, with parents or guardians often making decisions regarding vaccination. This study assessed how parents’ knowledge, attitudes, and health beliefs about influenza vaccination influenced their intentions to vaccinate their adolescent children. Methods: This descriptive survey was approved by the Institutional Review Board of Kyung Hee University for use between December 1 and 31, 2022. Parents of adolescents aged 13–19 years were surveyed face-to-face and online using a modified tool to evaluate their vaccination intentions, knowledge, attitudes, and health beliefs regarding their children’s influenza vaccination. The analysis included 149 responses and involved methods such as calculating means, standard deviations, t-tests, analyses of variance, Scheffe tests, correlations, and hierarchical regressions. Results: On a 7-point scale, the mean score for parental intention to vaccinate their adolescents was 4.99±1.24. Hierarchical regression analysis revealed that positive attitudes towards influenza vaccination, television and radio information, and perceived benefits influenced children’s vaccination intentions, with positive parental attitudes being the most significant factor. The independent variables accounted for 66.7% of the variance in vaccination intentions. Conclusion To improve parental intentions to vaccinate adolescent children against influenza, promoting vaccination benefits and safety through the media is crucial to enhance favorable attitudes. Initiatives that strengthen positive parental attitudes towards influenza vaccination and increase awareness of its benefits can effectively boost vaccination intentions.
