Purpose: This study analyzed the influence of dietary lifestyle and nutritional knowledge on the online food-purchasing behaviors of adults in Jeju. Methods: The study sampled 300 adults aged 18 to 69 years in Jeju, excluding incomplete responses or declined consent. The data were analyzed using the SPSS Win Program (ver 21.0), using principal component analysis, cluster analysis, frequency analysis, χ2-test, t-test, and analysis of variance. The significant results were examined using a Duncan’s multiplerange test. The survey questions assessed participants’ demographic information, dietary lifestyle, nutritional knowledge, and online food-purchasing habits. Results: Among the participants, dietary lifestyles could be classified into health-seeking, convenience-seeking, and taste-seeking clusters, with each showing distinct characteristics regarding nutrition knowledge and online food purchase behaviors. In particular, the ‘convenience-seeking’ cluster showed lower health-consciousness and nutrition knowledge and preferred convenience foods, while the ‘health-seeking’ cluster exhibited moderate nutrition knowledge and favored functional foods. The ‘diet-conscious’ cluster showed a higher level of nutritional awareness and made more frequent online purchases, particularly health and convenience foods. Furthermore, individuals with high nutrition knowledge were more focused on food labeling and verification. Moreover, dietary lifestyles significantly influenced consumer behaviors regarding online food purchases, including product preferences and the depth of food information reviewed. Conclusion This study underscores the fundamental role of dietary lifestyles and nutritional knowledge in shaping consumer behaviors regarding online food purchases among Jeju residents. These findings provide a foundation for developing tailored nutrition education materials that align with diverse dietary lifestyles. Furthermore, these insights can guide online food retailers in optimizing product information and marketing strategies to cater to the preferences of major consumer groups.

Spondylocarpotarsal synostosis syndrome (SCTS) is a rare genetic disorder characterized by vertebral fusion, short stature, and skeletal anomalies. SCTS is primarily associated with mutations in filamin B. However, in this report, we present a unique case of SCTS in a 28-year-old male who complained of neck and shoulder pain persisting for 1 year. His clinical presentation included radioulnar synostosis, cervical spine anomalies (scoliosis and agenesis of the posterior arch of C1), and a history of polydactyly. Genetic analysis revealed mutations in GMNN and DLL1. To the best of our knowledge, this is the first report on the association of SCTS with these genes.

Background/Aims: Early diagnosis of esophageal cancer (EC) remains challenging despite the increasing frequency of endoscopic screenings globally. The rapidly increasing number of endoscopic screenings performed over a certain period might influence diagnostic performance. This study evaluated the association between the number of endoscopic screenings and EC detection rates in a nationwide cohort. Methods: This retrospective population-based study used the Korean National Cancer Screening Program database, comprising 32,774,742 males and females aged ≥40 years between 2015and 2019. Negative binomial regression model and least-squares mean evaluation were used to assess the association between month of the year and EC detection rates. Results: This study enrolled 28,032,590 participants who underwent upper endoscopy. The number of participants in the fourth quarter (October to December: 10,923,142 [39.0%]) was 2.1 times higher than that in the first quarter (January to March: 5,085,087 [18.1%]); this trend continued for all 5 years. Contrarily, detection rates for EC in the fourth quarter (0.08/1,000 person) were half that in the first quarter (0.15/1,000 person). The odds of detecting EC were lowest in November; in 2015 the odds were 0.57 (95% confidence interval, 0.41 to 0.79; p=0.001) times lower and in 2016, they were 0.51 (95% confidence interval, 0.37 to 0.68; p<0.001) times lower compared to January. The predicted detection rates showed a decreasing trend toward the end of the year (p>0.05 for all). Conclusions The workload of endoscopists increased excessively with the rising number of endoscopies toward the end of the year, which was reflected by the decreased EC detection rates during this period.

Purpose: This study aimed to investigate whether levetiracetam (LEV), the most used antiepileptic drug, influences survival in patients with glioblastoma (GBM), using a national database. Materials and Methods: This study used data from the Korea Health Insurance Review and Assessment database. Patients diagnosed with GBM between 2007-2018 treated with standard therapy were included. The study population was divided into long-term (≥ 60 days) and short-term (< 30 days) LEV groups. A separate long-term valproic acid (VPA) group (≥ 60 days) was identified for comparison. Demographics, disease characteristics, and treatment parameters were collected. Kaplan-Meier method and Cox regression were used to compare survival outcomes between the groups. Results: Overall, 2,971 patients were included, with 1,319 and 1,652 in the short-term and long-term LEV groups, respectively. The median overall survival (OS) for the entire population was 19.15 months post-surgery. Kaplan-Meier analysis revealed a significantly longer median OS in the long-term LEV group versus the short-term LEV group. After adjusting for confounders, Cox proportional hazard analysis revealed an association of long-term LEV use with improved survival, which was also observed in a subgroup analysis of patients without preoperative seizure history. The long-term LEV group demonstrated longer median OS, compared with the long-term VPA group. Conclusion Our nationwide population-based study found an association between long-term LEV use and improved survival in patients with GBM, regardless of preoperative seizure history. Prospective studies are needed to validate these findings and investigate the potential impact of LEV on the survival outcomes of patients with GBM.

Purpose: Transversus abdominis plane (TAP) block is a promising technique for postoperative pain control. In this study, we aimed to evaluate the efficacy of the TAP block in managing postoperative pain after laparoscopic totally extraperitoneal (TEP) inguinal hernia repair. Methods: In this retrospective study, medical records of patients who had received ultrasonography-guided TAP blocks after surgery from January 2019 to August 2023 were reviewed and compared with those of patients who had not received. Propensity score matching was controlled for age as a confounder. Postoperative pain levels were measured using the numeric rating scale (NRS). Results: After matching, 95 patients were included in each group. The TAP block group (2.7 vs. 4.0, P < 0.001) had significantly lower NRS scores immediately and early postoperative pain than the control group (1.9 vs. 2.5, P < 0.001). However, there was no significant difference between the 2 groups in terms of postoperative complications (P > 0.05). Conclusion TAP block is effective and safe for managing immediate and early postoperative pain in laparoscopic TEP inguinal hernia repair and does not increase the risk of complications.
