Purpose:
To investigate the outcomes of brolucizumab reinjection after intraocular inflammation (IOI) development.
Methods:
This retrospective study analyzed patients with brolucizumab injections from April 2021 to January 2024. Patients who developed IOI after brolucizumab were included and categorized into subgroups depending on reinjection, discontinuation, and further IOI development.
Results:
A total of 472 eyes of 432 patients received brolucizumab injections. Thirty-eight cases developed IOI at least once, and 25 continued brolucizumab. Sixteen cases had no more IOI events, and nine experienced a second or more IOI events. Among the nine cases, three maintained brolucizumab injections despite IOI recurrence. The incidence of IOI was 8.1% based on the number of eyes (38 of 472 eyes) and 2.0% based on the number of brolucizumab injections (50 of 2,468 injections). The incidence of occlusive retinal vasculitis was 0.2% (1 of 472 eyes). The recurrence rate was 23.7% (9 of 38 eyes). The average number of injections between the first brolucizumab injection and the injection date on which IOI first developed was 2.15 times in the no-reinjection group, 3.44 times in the no-IOI-recurrence group, and 2.0 times in the second-IOI-episode group. Time to IOI occurrence in cases with first IOI episode was 18.60 ± 16.73 days, with 15 cases developing IOI within 1 week.
Conclusions
This study elucidates the real-world incidence of brolucizumab associated IOIs, with a description of information related to reinjections after the IOI episodes. A comprehensive understanding of brolucizumab reinjection is essential for its optimal utilization.

Ideal sedation education for gastrointestinal endoscopy should encompass all medications used in sedation therapy, and facilitate appropriate application in clinical practice by combining theoretical and practical education according to each country’s situation. The educational goals for endoscopic sedation in Korea have already been announced, and theoretical training is regularly conducted by the Korean Society of Gastrointestinal Endoscopy (KSGE). However, no official core curriculum for sedation during gastrointestinal endoscopy exists in Korea. Therefore, a practical curriculum aligned with Korea’s clinical context should be developed. The Endoscopic Sedation Committee of KSGE has identified these challenges and proposed a core curriculum for sedation during endoscopy. Firstly, in terms of theory, it would be beneficial to maintain current education. Secondly, since practical training is still lacking, it would be beneficial to have practical hands-on training. To accomplish this, each simulation center should provide basic practical training such as airway maintenance and advanced teamwork skills. This review presents a detailed curriculum for safe sedation in gastrointestinal endoscopy, developed based on Korea’s specific needs and supported by current literature.

Journal of Korean Neuropsychiatric Association 2025;64(4):277-288
Objectives:
This study examined the psychosocial factors that influence the continuation of clozapine use among individuals with schizophrenia. This examination was conducted through indepth qualitative interviews.
Methods:
Thirty-one adults diagnosed with schizophrenia (Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition) who had been taking Clozapine ® for at least 3 months were interviewed. Data were collected from May to October 2024 and analyzed using Braun and Clarke’s thematic analysis.
Results:
Two overarching themes emerged: 1) transformation of perceptions and engagement with treatment, including initial resistance stemming from severe symptoms and lack of insight, experiences of coercive interventions, rebuilding trust in the mental health system, and evolving attitudes toward psychiatric medications; and 2) personal recovery and social support, encompassing coping with side effects, recognizing symptom improvement and renewed hope, and the pivotal roles of family and therapeutic alliance. Trust in healthcare providers and emotional support from family were central to sustained adherence to clozapine.
Conclusion
Sustained clozapine use in schizophrenia patients is influenced by intertwined psychological, relational, and contextual factors. Acceptance of treatment was supported by symptom improvement, family support, and trust in healthcare providers. These elements contributed to medication adherence and broader functional recovery. A person-centered, integrated approach is essential to promote continued use and long-term outcomes.

Psychiatry Investigation 2025;22(12):1339-1349
Objective:
The study aimed to investigate whether RSPO2 gene polymorphisms are associated with schizophrenia susceptibility, focusing on five specific single nucleotide polymorphisms (SNPs). Additionally, the study evaluated the expression of Rspo2 in a schizophrenic-like mouse model and examined its relationship with clinical symptoms.
Methods:
The study included 159 schizophrenia patients and 448 controls. Clinical symptoms were assessed using the Operational Criteria Checklist for Psychotic Illness. Genotyping of five RSPO2 SNPs was performed to identify potential genetic associations with schizophrenia. Rspo2 mRNA expression levels were measured in the brains of MK-801-induced schizophrenic-like mice. Functional analysis of the rs374810 SNP was conducted using a luciferase assay to evaluate its effect on gene activity. Statistical analyses were used to compare genotype and allele frequencies and assess correlations with clinical outcomes.
Results:
Significant associations were found between schizophrenia and two SNPs, rs374810 and rs423940. The A allele of rs374810 and the T allele of rs423940 were linked to an increased risk of schizophrenia (p=0.0049 and p=0.0044, respectively). Functional analysis revealed that the A allele of rs374810 significantly increased luciferase activity compared to the G allele, indicating a potential functional role. RSPO2 expression was also altered in the schizophrenic-like mouse model, suggesting its involvement in schizophrenia pathogenesis.
Conclusion
The findings indicate that RSPO2 gene polymorphisms, particularly rs374810 and rs423940, may contribute to schizophrenia susceptibility. Therefore, RSPO2 expression may be associated with the susceptibility to schizophrenia in the Korean population.
