Objectives: This study was conducted to investigate the relationship between watching Mukbang (eating broadcasts) and dietary and health behavior in adults who watch Mukbang Methods: The questionnaire was administered on a self-written basis through online and offline formats to 800 adults (400 men and 400 women). The contents of the survey consisted of general characteristics, Mukbang viewing time per week, breakfast intake frequency, preference for menus when viewing Mukbang , delivery food intake frequency per week, late meal intake frequency per week, and health behavior. The subjects were divided into three groups according to Mukbang viewing time. Results: The body weight of viewers was significantly higher whenMukbang viewing time was over 14 hours for both men and women. In particular, based on the BMI (body mass index), those who watched Mukbang for more than 14 hours were found to be overweight. People with more than 14 hours of Mukbang viewing time per week were found to prefer mostly carbohydrate-rich food and meat, while those with less than 7 hours of Mukbang viewing time per week showed a higher preference for vegetables and fruits. An analysis of the frequency of breakfast eaten showed that the rate of skipping breakfast was the highest for those who watched Mukbang for more than 14 hours per week, and the rate of eating breakfast daily was the highest in the case of fewer than 7 hours of viewing. In the case of high Mukbang viewing time per week, the frequency of food delivery and night eating was high. When Mukbang viewing time was high, the viewer’s interest in health was low and the frequency of exercising too was low. Conclusions Viewers with high Mukbang viewing time showed undesirable health and eating behavior. Thus, it is believed that proper nutrition education on improving eating habits and raising the awareness of correct eating habits is necessary for such viewers.

PURPOSE: Rebamipide is a propionic acid derivative that inhibits superoxide production and removes hydroxyl radicals. This study was performed to investigate the effects of adding rebamipide to semen, in an effort to determine if reactive oxygen species (ROS) production and lipid peroxidation of the sperm cell membrane as well as an improvement in seminal parameter and fertilizing capacity under oxidative stress was inhibited. MATERIALS AND MTHODS: Semen was collected from 30 normal healthy volunteers by masturbation after at least 48 hours abstinence. After liquefaction of the semen at room temperature, the prepared sperm was diluted with a sperm wash media to a uniform density of 20x106/ml. The semen was treated with 0.25ml of 0.2mM FeSO4 and 1mM sodium ascorbate for 60 min in the presence of various rebamipide concentrations (0, 10, 30, 100, and 300microM). ROS production, sperm motility, vitality, fertilizing capacity and the level of lipid peroxidation were analyzed by chemiluminescence, computer assisted semen analysis, eosin-nigrosin staining, a hypo-osmotic swelling test and the thiobarbituric acid method, respectively. RESULTS: Rebamipide at 100 and 300microM increased the sperm motility (p<0.05) but did not affect the sperm vitality. The ROS production and lipid peroxidation in the sperms treated with FeSO4/sodium ascorbate were inhibited by rebamipide in a dose-dependent fashion (p<0.05 in each). The total swelling rate of the hypo-osmotic swelling test was also increased by high rebamipide concentrations (100 and 300microM), respectively 49.2 17.9 and 50.8 21.7% (p<0.05). CONCLUSIONS: These results suggest rebamipide is an effective free radical scavenger and may be useful as an oral antioxidant in patients with male infertility due to increased ROS generation. However, further study to be possible the clinical use of rebamipide for improve the fertilizing capacity in male infertility is required.

OBJECTIVE: In this study, we evaluated the prevalence of allergic disease in offsprings delivered via the delivery modes of vaginal delivery vs. planned Cesarean section vs. Cesarean section with labor. METHODS: This study included 175 mother-neonate pairs from Severance Hospital who were enrolled in the Cohort for Childhood Origin of Asthma and allergic diseases study. Information regarding prenatal environmental factors, delivery, and diagnosis of allergic diseases was obtained from a questionnaire and medical record review. Patients with at least 3 years of follow-up data were included in this study. Results were adjusted for sex, birth weight, gestational age at birth, season of birth, neonatal intensive care unit admission, parity, breastfeeding, and maternal factors. RESULTS: A total of 175 offsprings were eligible for analysis. Among the subjects, 52.0% were delivered by vaginal delivery, 34.3% by planned Cesarean section, and 16.6% by Cesarean section with labor. Fifty-nine offsprings (33.7%) were diagnosed with allergic disease at a median age of 1 year (range 0.5–3 years). The prevalence of allergic disease was not associated with delivery mode after adjusting for confounding variables. Time period from membrane rupture to delivery, duration of the active phase, and the beginning of the pelvic division prior to Cesarean section were not associated with allergic disease development in offsprings. CONCLUSION: Cesarean section, irrespective of the occurrence of labor before surgery, did not increase the prevalence of allergic disease in infants up to 3 years of age.

Antithrombotic agents, including antiplatelet agents and anticoagulants, are widely used in Korea because of the increasing incidence of cardiocerebrovascular disease and the aging population. The management of patients using antithrombotic agents during endoscopic procedures is an important clinical challenge. The clinical practice guidelines for this issue, developed by the Korean Society of Gastrointestinal Endoscopy, were published in 2020. However, new evidence on the use of dual antiplatelet therapy and direct anticoagulant management has emerged, and revised guidelines have been issued in the United States and Europe. Accordingly, the previous guidelines were revised. Cardiologists were part of the group that developed the guideline, and the recommendations went through a consensus-reaching process among international experts. This guideline presents 14 recommendations made based on the Grading of Recommendations, Assessment, Development, and Evaluation methodology and was reviewed by multidisciplinary experts. These guidelines provide useful information that can assist endoscopists in the management of patients receiving antithrombotic agents who require diagnostic and elective therapeutic endoscopy. It will be revised as necessary to cover changes in technology, evidence, or other aspects of clinical practice.

PURPOSE: Previously, we reported the presence of virus-encoded microRNAs (miRNAs) in the urine of prostate cancer (CaP) patients. In this study, we investigated the expression of two herpes virus-encoded miRNAs in prostate tissue. METHODS: A total of 175 tissue samples from noncancerous benign prostatic hyperplasia (BPH), 248 tissue samples from patients with CaP and BPH, and 50 samples from noncancerous surrounding tissues from these same patients were analyzed for the expression of two herpes virus-encoded miRNAs by real-time polymerase chain reaction (PCR) and immunocytochemistry using nanoparticles as molecular beacons. RESULTS: Real-time reverse transcription-PCR results revealed significantly higher expression of hsv1-miR-H18 and hsv2-miRH9- 5p in surrounding noncancerous and CaP tissues than that in BPH tissue (each comparison, P<0.001). Of note, these miRNA were expressed equivalently in the CaP tissues and surrounding noncancerous tissues. Moreover, immunocytochemistry clearly demonstrated a significant enrichment of both hsv1-miR-H18 and hsv2-miR-H9 beacon-labeled cells in CaP and surrounding noncancerous tissue compared to that in BPH tissue (each comparison, P<0.05 for hsv1-miR-H18 and hsv2- miR-H9). CONCLUSIONS: These results suggest that increased expression of hsv1-miR-H18 and hsv2-miR-H95p might be associated with tumorigenesis in the prostate. Further studies will be required to elucidate the role of these miRNAs with respect to CaP and herpes viral infections.
