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.

Psychiatry Investigation 2024;21(11):1203-1210
Objective:
This study aimed to explore the relationship between suicidal ideation and specific trauma and social discrimination among North Korean defectors.
Methods:
A total of 448 North Korean defectors were recruited from online and offline communities and counseling centers. Participants provided sociodemographic and psychiatric history information via an online survey. Various assessment tools, including the Traumatic Event Checklist for North Korean Defectors, International Trauma Questionnaire, Experiences of Discrimination Scale, UCLA Loneliness Scale (short-form), and World Health Organization Quality of Life Instrument, Short Form (WHOQOL-BREF), were employed. Multiple logistic regression analysis was used to examine the association between suicidal ideation and different types of trauma and discrimination.
Results:
Among participants, 38.4% reported experiencing suicidal ideation. The most prevalent trauma was “unwanted separation from spouse, parent, or sibling” (69.4%), and the primary form of discrimination was “unfairness during employment” (35.7%). After adjusting for relevant variables, experiencing “extreme life-threatening hardship,” “unwanted separation from a child,” and “discrimination in income” significantly increased the likelihood of suicidal ideation. Importantly, unlike other refugee groups, interpersonal violence like torture or sexual abuse did not significantly contribute to suicidal ideation in this population. These findings highlight the unique vulnerabilities of North Korean defectors and suggest that income-related discrimination, unwanted separation from children, and life-threatening hardships are critical factors influencing suicidal ideation. Limitations such as recall biases and the cross-sectional nature of the data should be acknowledged.
Conclusion
This study underscores the need for tailored psychiatric support for North Korean defectors, recognizing their distinctive needs compared to other refugee populations.

Journal of Gynecologic Oncology 2024;35(2):e44-
This fifth revised version of the Korean Society of Gynecologic Oncology practice guidelines for the management of cervical cancer incorporates recent research findings and changes in treatment strategies based on version 4.0 released in 2020. Each key question was developed by focusing on recent notable insights and crucial contemporary issues in the field of cervical cancer. These questions were evaluated for their significance and impact on the current treatment and were finalized through voting by the development committee. The selected key questions were as follows: the efficacy and safety of immune checkpoint inhibitors as firstor second-line treatment for recurrent or metastatic cervical cancer; the oncologic safety of minimally invasive radical hysterectomy in early stage cervical cancer; the efficacy and safety of adjuvant systemic treatment after concurrent chemoradiotherapy in locally advanced cervical cancer; and the oncologic safety of sentinel lymph node mapping compared to pelvic lymph node dissection. The recommendations, directions, and strengths of this guideline were based on systematic reviews and meta-analyses, and were finally confirmed through public hearings and external reviews. In this study, we describe the revised practice guidelines for the management of cervical cancer.

Journal of Retina 2024;9(2):119-126
Purpose:
This study aims to evaluate the quality of and trends in artificial intelligence (AI) chatbot responses to questions related to age-related macular degeneration (AMD) and to analyze the frequency of incorrect key information.
Methods:
Three chatbots, ChatGPT 3.5, ChatGPT 4.0, and Gemini, were used in this study. Nine questions were formulated covering general information about: 1) AMD, 2) AMD treatment options, 3) effects and side effects of intraocular injections. Each question was queried three times with each of the three chatbots using two different accounts. Responses to items 1–3 were rated as poor/acceptable/good, and the frequency of incorrect key information was noted.
Results:
Overall, the majority of the queries received acceptable or good responses. Poor-quality responses were noted in 16.7% of ChatGPT 3.5 responses. Incorrect key information was present in 6.5% of all responses.
Conclusions
While AI chatbots generally provided acceptable responses to questions regarding AMD, some responses contained incorrect key information, suggesting the need for caution when accessing medical information through AI chatbots.
10.Short-term Anatomical Outcomes of Switching from Bevacizumab to the Ranibizumab Biosimilar CKD-701 in Neovascular Age-related Macular Degeneration
Journal of Retina 2024;9(2):127-133
Purpose:
To evaluate and report the short-term anatomical effects of switching from bevacizumab to the ranibizumab biosimilar CKD-701 in patients undergoing treatment for neovascular age-related macular degeneration (AMD).
Methods:
A retrospective medical record analysis was conducted on patients receiving bevacizumab therapy for neovascular AMD who were subsequently switched to CKD-701. The changes in central macular thickness and frequency of intraretinal/subretinal fluid before and after a single CKD-701 injection were compared with those before and after a single bevacizumab injection.
Results:
A total of 20 eyes was included in the study. Following bevacizumab injection, the mean central macular thickness decreased by 14.9 ± 57.6 µm, with intraretinal and subretinal fluid observed in 75.0%/55.0% before injection and 60.0%/55.5% after injection, respectively. Following CKD-701 injection, the mean central macular thickness decreased by 34.9 ± 57.4 µm, with intraretinal and subretinal fluid observed in 75.0%/56.0% before injection and 45.0%/40.0% after injection, respectively. There were no significant differences between the two groups in terms of changes in central macular thickness (p = 0.204), frequency of intraretinal fluid (p = 1.000), and subretinal fluid (p = 0.748) observed before injection or in frequency of intraretinal fluid (p = 0.527) and subretinal fluid (p = 0.527) after injection.
Conclusions
The short-term anatomical outcomes following CKD-701 injection in neovascular age-related macular degeneration showed no significant difference compared to the short-term outcomes following bevacizumab injection previously administered.
