Instant noodle consumption is associated with cardiometabolic risk factors among college students in Seoul

BACKGROUND/OBJECTIVES: Increased consumption of instant noodles has recently been reported to be positively associated with obesity and cardiometabolic syndrome in South Korea, which has the highest per capita instant noodle consumption worldwide. This study aimed to investigate the association between instant noodle consumption and cardiometabolic risk factors among college students in Seoul. SUBJECTS/METHODS: The study subjects consisted of 3,397 college students (1,782 male; 1,615 female) aged 18-29 years who participated in a health checkup. Information on instant noodle consumption was obtained from the participants' answers to a question about their average frequency of instant noodle intake over the 1 year period prior to the survey. RESULTS: Statistical analysis using a general linear model that adjusted for age, body mass index, gender, family income, health-related behaviors, and other dietary factors important for cardiometabolic risk, showed a positive association between the frequency of instant noodle consumption and plasma triglyceride levels, diastolic blood pressure, and fasting blood glucose levels in all subjects. Compared to the group with the lowest frequency of instant noodle intake (≤ 1/month), the odds ratio for hypertriglyceridemia in the group with an intake of ≥ 3/week was 2.639 [95% confidence interval (CI), 1.393–5.000] for all subjects, while it was 2.149 (95% CI, 1.045–4.419) and 5.992 (95% CI, 1.859–21.824) for male and female students, respectively. In female students, diastolic blood pressure was also higher among more frequent consumers of instant noodles. CONCLUSIONS: Our results suggest that frequent consumption of instant noodles may be associated with increased cardiometabolic risk factors among apparently healthy college students aged 18–29 years.

The effect and optimal dose of sufentanil in reducing injection pain of microemulsion propofol / 대한마취과학회지

BACKGROUND: Propofol is used as an induction and maintenance agent for general anesthesia but it can cause adverse reactions like hyperlipidemia, growth of microorganisms, and pulmonary embolisms. Microemulsion propofol was developed to avoid these side effects but incidence and severity of pain on injection is higher than with lipid emulsion propofol. We aimed to compare the effects of sufentanil in analgesic doses for reducing the injection pain of microemulsion propofol. METHODS: The candidates included eighty patients, 19-60 years old and ASA I-II. They were randomly classified into four groups and pretreated with normal saline, sufentanil 0.1 microg/kg, 0.2 microg/kg or 0.3 microg/kg before injection of microemulsion propofol. Five minutes after receiving pretreatment drug, 2 mg/kg of microemulsion propofol was injected and VAS was recorded. RESULTS: There were no significant differences in the incidence of injection pain among the groups. Severity of injection pain was significantly lower in the sufentanil 0.3 microg/kg group than normal saline and sufentanil 0.1 microg/kg group. Significant differences in blood pressure and heart rate were observed in sufentanil groups only after endotracheal intubation. One patient each in sufentanil 0.1 microg/kg and 0.3 microg/kg group experienced mild cough, one from sufentanil 0.3 microg/kg group experienced dizziness and another showed signs of hypoxia. One patient each in normal saline and sufentanil 0.1 microg/kg group showed clinical symptoms of phlebitis in the injection area. CONCLUSIONS: Pretreatment with sufentanil 0.3 microg/kg reduced the severity of microemulsion propofol injection pain without increasing arterial blood pressure and heart rate after endotracheal intubation.

Hydromediastinum and bilateral hydrothorax after right subclavian vein catheterization: A case report / 대한마취과학회지

In many clinical settings, patients undergoing major surgery and patients with critical illness or cancer routinely receive a central venous catheter (CVC). Although several complications including hematoma formation, hemothorax, hydrothorax, chylothorax and cardiac tamponade with vascular injury are associated with the placement of CVCs, their incidence are not frequent. Especially, hydromediastinum and bilateral hydrothorax are very rare. We experienced an unusual complication of hydromediastinum and bilateral hydrothorax by left brachiocephalic vein perforation with misplacement of the catheter tip after right subclavian vein catheterization.
