This study aimed to assess the utilization trends of pulmonary rehabilitation (PR) among lung cancer patients in Korea using the National Health Insurance Service (NHIS) database (2017 to 2021). PR was introduced and covered under the NHIS in 2016, primarily for chronic obstructive pulmonary disease, but recent evidence suggests its benefits for lung cancer patients. Data extraction was based on Korea Informative Classification of Diseases 8th revision codes C33 and C34, with PR prescriptions identified by codes MM440 and MM290.Descriptive statistical analysis was performed, and propensity score matching was used for comparison between PR and non-PR groups. Results showed a significant increase in PR utilization, with the number of patients receiving PR (MM440) rising from 1,002 in 2017 to 3,723 in 2021, indicating a 3.7-fold increase. However, the proportion of patients receiving PR remained low at 2.9% in 2021. Enhanced access to PR services and improved evaluation strategies are essential for optimizing patient outcomes.

Objectives: This study examined the mediating effects of smartphone dependence on the relationship between anxiety and delayed bedtime and analyzed the group differences based on gender and economic difficulties caused by the COVID-19 pandemic among Korean adolescents. Methods: Data from 4254 middle school students living in metropolitan areas and cohabiting with highly educated parents were analyzed using the 2020 Korea Youth Risk Behavior Survey.The participants were divided into four groups based on gender and economic difficulties caused by COVID-19. T-tests, analysis of variance, and Pearson correlation analysis were conducted on each variable. The Baron–Kenny method and Sobel tests were used to verify the mediating effects. Results: Female students showed higher levels of anxiety, smartphone dependence, and delayed bedtime. Groups experiencing economic difficulties due to COVID-19 reported higher levels of anxiety and smartphone dependence. Across all groups, positive correlations were observed between anxiety, smartphone dependence, and delayed bedtime. Smartphone dependence partially mediated the relationship between anxiety and delayed bedtime, except in the group of male students experiencing economic difficulties caused by COVID-19. Conclusion This study confirmed the associations between anxiety, smartphone dependence, and delayed bedtime among adolescents, suggesting the need for interventions related to smartphone use to support the mental health of adolescents in stressful situations.

Purpose: This study investigated the anti-inflammatory effects of Evodiae Fructus (EF) on hydrochloric acid (HCl)/ethanol-induced gastritis, focusing on its impact on oxidative stress by analyzing inflammatory cytokines and inflammation-related factors. The total polyphenol and flavonoid contents were determined through in vitro experiments, while the radical scavenging activity was confirmed using 2,2-diphenyl-1-picrylhydrazyl and 2,2’-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) assays. Methods: In vivo experiments were conducted on rats divided into 5 groups (n = 7/in each group): normal group (Normal), 150 mM HCl/60% ethanol-induced gastritis group (Control), 150 mM HCl/60% ethanol-induced gastritis group administered 10 mg/kg sucralfate (SC), 150 mM HCl/60% ethanol-induced gastritis group administered EF at the doses of 100 mg/kg or 200 mg/kg (EF100 or EF200). The mice were pretreated with the extract (EF) or drug (SC), and after 1 hour, 150 mM HCl/60% ethanol (v/v) mixture was administered orally. Reactive oxygen species (ROS) levels, peroxynitrite (ONOO − ), and pro-inflammatory cytokines including tumor necrosis factor-α and interleukin-1 beta were assessed in serum. Additionally, western blotting of the gastric tissues confirmed the expression of inflammation-related proteins. Results: EF alleviated the gastric mucosal damage caused by 150 mM HCl/60% ethanol.The assessment of oxidative stress in the serum showed that EF significantly reduced ROS and ONOO − levels and significantly decreased the levels of pro-inflammatory cytokines. Western blot analysis revealed that EF reduced ROS-generating nicotinamide adenine dinucleotide phosphate oxidase subunits, including gp91phox , p22phox , and p47phox . Additionally, EF mitigated the inflammation by inhibiting the mitogen-activated protein kinase signaling pathway. Conclusion These results indicate that EF is a potential herbal medicine candidate for the treatment of oxidative stress-induced gastritis.

Background: The quality-of-life of patients with irritable bowel syndrome is low; incorrect diagnosis/treatment causes economic burden and inappropriate consumption of medical resources. This survey-based study aimed to analyze the current status of irritable bowel syndrome treatment to examine differences in doctors’ perceptions of the disease, and treatment patterns. Methods: From October 2019 to February 2020, the irritable bowel syndrome and Intestinal Function Research Study Group of the Korean Society of Neurogastroenterology and Motility conducted a survey on doctors working in primary, secondary, and tertiary healthcare institutions. The questionnaire included 37 items and was completed anonymously using the NAVER platform (a web-based platform), e-mails, and written forms. Results: A total of 272 doctors responded; respondents reported using the Rome IV diagnostic criteria (amended in 2016) for diagnosing and treating irritable bowel syndrome.Several differences were noted between the primary, secondary, and tertiary physicians’ groups. The rate of colonoscopy was high in tertiary healthcare institutions. During a colonoscopy, the necessity of random biopsy was higher among physicians who worked at tertiary institutions. ‘The patient did not adhere to the diet’ as a reason for ineffectiveness using low-fermentable oligo-, di-, and mono-saccharides, and polyols diet treatment was higher among physicians in primary/secondary institutions, and ‘There are individual differences in terms of effectiveness’ was higher among physicians in tertiary institutions. In irritable bowel syndrome constipation predominant subtype, the use of serotonin type 3 receptor antagonist (ramosetron) and probiotics was higher in primary/secondary institutions, while serotonin type 4 receptor agonist was used more in tertiary institutions. In irritable bowel syndrome diarrhea predominant subtype, the use of antispasmodics was higher in primary/secondary institutions, while the use of serotonin type 3 receptor antagonist (ramosetron) was higher in tertiary institutions. Conclusion Notable differences were observed between physicians in primary/secondary and tertiary institiutions regarding the rate of colonoscopy, necessity of random biopsy, the reason for the ineffectiveness of low-fermentable oligo-, di-, and mono-saccharides, and polyols diet, and use of drug therapy in irritable bowel syndrome. In South Korea, irritable bowel syndrome is diagnosed and treated according to the Rome IV diagnostic criteria, revised in 2016.
