Background/Aims: The coronavirus disease 2019 (COVID-19) pandemic has significantly impacted global health, exacerbated metabolic health issues, and altered lifestyle behaviors. This study examined the sex-specific impact of the COVID-19 outbreak on the incidence of metabolic syndrome using data from the Korea National Health and Nutrition Examination Survey (KNHANES). Methods: Data from the KNHANES VII (2018) and VIII (2019–2021), including 15,499 participants, were analyzed. The study population was stratified by sex, and further subdivisions were conducted based on the timeframe relative to the COVID-19 outbreak. Variables such as age, education level, household income, smoking status, and high-risk drinking were analyzed to assess their influence on the prevalence of metabolic syndrome. Results: The overall prevalence of metabolic syndrome significantly increased from 28.11% before the outbreak to 29.69% after the outbreak. Both males and females reported significant increases in waist circumference and fasting glucose levels. Age and education level differentially influenced the prevalence of metabolic syndrome between the sex. Smoking was significantly associated with increased prevalence in males, whereas high-risk drinking was associated with increased prevalence in males and decreased prevalence in females. Conclusions The COVID-19 pandemic has significantly increased the prevalence of metabolic syndrome with notable sex-specific differences. These findings highlight the need for sex-specific public health interventions to mitigate the impact of the pandemic on metabolic health.

BACKGROUND: Everolimus-eluting stent (EES) implantations have a relatively low rate of major adverse cardiac event (MACE) and target lesion revascularization (TLR) in patients with off-label use. However, the clinical outcome in the Korean population regarding EES in patients with off-label use is not well known. OBJECTS: The aim of the current analysis was to compare the clinical outcomes of on-label and off-label EES use over a 2-year follow-up period. METHODS: Using patient-level data from a stent-specific, prospective, all-comer registry, we evaluated 987 patients (1,342 lesions) who received an EES (XIENCE V®, Abbott Vascular, Santa Clara, CA, USA) implantation between February 2009 and April 2011. The primary outcome was assessed: 2-year MACE (a composite endpoint of death from any cause, spontaneous myocardial infarction (MI), and any repeat revascularization). The clinical outcomes in the on- and off-label groups were compared at 2 years. RESULTS: The majority of patients (79.0%) were treated for ≥1 off-label indication. The median duration of the clinical follow-up in the overall population was 2.0 years (interquartile range 1.9–2.1). At 2-years after the EES implantation in the enrolled patients, MACE occurred in 71 (7.9%) patients, cardiac death in 12 (1.3%), MI in 4 (0.5%), target vessel revascularization (TVR) in 33 (3.8%), TLR in 22 (2.5%), and definite or probable stent thrombosis (ST) in 1 (0.1%). Off-label EES implantations tend to increase the risk of 2-year MACE (4.7% vs. 8.8%, p = 0.063) without statistical significance. However, the rates of TLR were higher in the off-label EES implantations (0.0% vs. 3.2%, p = 0.013). In the multivariable analysis, renal failure, previous bypass surgery, previous cerebrovascular accident, and left main lesions were associated with 2-year MACE in patients with EES implantations. CONCLUSIONS: The incidence of 2-year MACE was 7.9%, which that might be acceptable in all-comer patients treated with EES implantations. Although the off-label use of EES was not statistically associated with an increased risk of MACE, the TLR rate was higher in the off-label group, suggesting that physicians need to pay attention to high risk patients with the use of EES implantations.

Eight isoflavonoid compounds were isolated from the EtOAc fraction of Maackia amurensis which had shown the highest anti-Helicobacter pylori activity among the fractions, using medium pressure liquid chromatography and recrystallization. Based on the spectroscopic data including 1H-NMR, 13C-NMR, HMBC and MS data, the chemical structures of the isolates were determined to be (-)-medicarpin (1), afromosin (2), formononetin (3), tectorigenin (4), prunetin (5), wistin (6), tectoridin (7) and ononin (8). Anti-H. pylori activity of each compound was evaluated with broth dilution assay. As a result, (-)-medicarpin (1), tectorigenin (4) and wistin (6) showed anti-H. pylori activity. (-)-Medicarpin (1) exhibited the most potent growth inhibitory activity against H. pylori with the minimal inhibitory concentration (MIC)90 of 25 microM, and tectorigenin (4) with MIC90 of 100 microM ranked the second. This is the first study to show the anti-H. pylori activity of M. amurensis, and it is suggested that the stem bark of M. amurensis or the EtOAc fraction or the isolated compounds can be a new natural source for the treatment of H. pylori infection.

PURPOSE: This study was conducted to establish the production conditions through optimization of the production process of beverages using Aspergillus oryzae CF1001, and to analyze volatile compounds and antidiabetic activity. METHODS: The optimum condition was selected using the response surface methodology (RSM), through a regression analysis with the following independent variables gelatinization temperature (GT, X1), saccharogenic time (ST, X2), and dependent variable; DeltaE value (y). The condition with the lowest DeltaE value occurred with combined 45 min ST and 50degrees C GT. The volatile compounds were analyzed quantitatively by GC-MS. RESULTS: Assessment of antidiabetic activity of saccharogenic mixed grain beverage (SMGB) was determined by measurement of alpha-glucosidase inhibition activity, and glucose uptake activity and glucose metabolic protein expression by reverse transcriptase polymerase chain reaction (RT-PCR) and western blot analysis. Results of volatile compounds analysis, 62 kinds of volatile compounds were detected in SMGB. Palmitic acid (9.534% ratio), benzaldehyde (8.948% ratio), benzyl ethyl ether (8.792% ratio), ethyl alcohol (8.35% ratio), and 2-amyl furan (4.826% ratio) were abundant in SMGB. We confirmed that alpha-glucosidase inhibition activity, glucose uptake activity, and glucose-metabolic proteins were upregulated by SMGB treatment with concentration dependent manner. CONCLUSION: Saccharogenic mixed grain beverage (SMGB) showed potential antidiabetic activity. Further studies will be needed in order to improve the taste and functionality of SMGB.

The case of a 33-day-old boy with Pierre Robin syndrome using a Cook(R) airway exchange catheter in laryngeal mask airway-guided fiberoptic intubation is presented. After induction with sevoflurane, classical reusable laryngeal mask airway (LMA) #1 was inserted and ultrathin fiberoptic bronchoscope (FOB) was passed through. A Cook(R) airway exchange catheter (1.6 mm ID, 2.7 mm OD) was passed through the LMA under the guidance of the FOB but failed to enter the trachea despite many trials. Then, an endotracheal tube (3.0 mm ID) was mounted on the FOB and railroaded over the FOB. After successful intubation, the Cook(R) airway exchange catheter was placed in the midtrachea through the lumen of the endotracheal tube. Even though the tracheal tube was accidentally displaced out of the trachea during LMA removal, the endotracheal tube could be easily railroaded over the airway exchange catheter.

Several autoimmune and chronic inflammatory conditions have been consistently linked with an increased risk of hematologic malignancies. Although ankylosing spondylitis (AS) is a chronic inflammatory disease, previous studies have demonstrated that it is not associated with an increase in risk of malignant lymphomas. Cases of AS accompanied by hematologic malignancies such as multiple myeloma, chronic myelogenous leukemia, and Hodgkin's disease have been reported. In Korea, AS with non-Hodgkin's lymphoma or follicular lymphoma has not been reported. We experienced a 38-year-old male who had been diagnosed with follicular lymphoma with bone metastasis, who achieved complete remission after having been treated with chemotherapy, developed new inflammatory back pain. An MRI of his hip showed an active inflammation of the left sacroiliac joint and a positive HLA-B27. The patient was diagnosed with AS and was treated with naproxen, which improved the pain in his back and buttock.
