Objectives: This study aimed to compare the quality of life (QoL) of children with attention-deficit/hyperactivity disorder (ADHD) before and during coronavirus disease-2019 (COVID-19) and to examine how their QoL is affected by emotional and environmental factors during COVID-19. Methods: Participants in the pre-COVID-19 (n=43) and COVID-19 (n=36) groups were recruited from the same university hospital. The Pediatric Quality of Life Inventory (PedsQL) 4.0 Child Self-report, the Children’s Depression Inventory (CDI), the Revised Children’s Manifest Anxiety Scale (RCMAS), the PedsQL 4.0 Parent Proxy Report, and the Conners’ Parent Rating Scale (CPRS) were employed. Independent t-tests, Pearson’s correlation analysis, and multiple regression analysis were conducted. Results: Caregivers assessed the children’s QoL more negatively than the children themselves in both groups. Children with ADHD evaluated their physical function more negatively and anxiety was significantly higher in the COVID-19 group. In the COVID-19 group, the PedsQL child self-report was significantly predicted by the CPRS, the CDI, and environmental factors (i.e., relation to child and monthly household income). Conclusion Children with ADHD in the COVID-19 group had a numerically lower QoL and significantly higher anxiety. To improve QoL, it is important to deal with not only depression but also ADHD symptoms and environmental factors.

Hypothalamic hamartomas (HHs) are nonneoplastic mass lesions located in the hypothalamus that can cause central precocious puberty (CPP) and/or gelastic seizures. Seckel syndrome 5 (OMIM210600, SCKL5) is a rare autosomal recessive genetic spectrum disorder characterized by intrauterine growth retardation, proportionate osteodysplastic primordial dwarfism, a wide range of intellectual disability, "bird-headed" facial features, and microcephaly with various structural brain abnormalities. Two siblings presented with short stature and small head circumference and were diagnosed with SCKL 5. The younger sister had HH with CPP and experienced a slipped capital femoral epiphysis during treatment. The 2 siblings had the same genetic variant but showed different phenotypes, which has not been reported previously; this study also as presents the first cases of SCKL5 diagnosed by genetic confirmation in Korea.

Objectives: We investigate relationship between suicide attempts and peripheral blood inflammatory markers in patients visiting the emergency department (ED) for psychiatric consultations, aiming to identify potential biomarkers for predicting suicide risk. Methods: We retrospectively reviewed medical records of 569 patients who were referred to psychiatric consultation at the ED from January 1, 2022 to December 31, 2022. Demographic and clinical characteristics and various blood test markers were analyzed. Analyses were performed to compare differences in blood markers between suicide attempters and non-attempters and among those with varying histories of suicide attempts. Results: Among 569 patients, 398 (69.9%) had attempted suicide. Significant differences in leukocytes, lymphocytes, eosinophils, red blood cells (RBCs), lactate dehydrogenase (LDH), and ketone bodies were observed between suicide attempters and non-attempters. Further analysis revealed that patients with a history of suicide attempts had higher lymphocyte and eosinophil counts but lower LDH and ketone body levels. An increasing frequency of past suicide attempts correlated with higher lymphocyte and eosinophil count and lower neutrophil-to-lymphocyte ratio, monocyte-to-lymphocyte ratio, platelet-to-lymphocyte ratio, systemic immune inflammatory index, glucose, LDH, and ketone body levels. Conclusions We identify blood markers associated with suicide attempts, indicating that leukocyte, lymphocyte, eosinophil, RBC count, LDH, and ketone body levels could serve as potential biomarkers for assessing suicide risk. Findings underscore importance of biological assessments in conjunction with psychological evaluations in predicting and preventing suicide attempts. Further research is needed to validate these biomarkers and understand mechanisms.

Objective: The study compared differences in various neurocognitive characteristics across treatment modalities among schizophrenia patients recruited in one city between July 2020 and June 2023 who were on regular medication. Methods: Of the 151 participants, 113 were included in the analysis. Participants were divided into community-based and hospital-based groups, and their demographics and clinical characteristics, including insight, quality of life, positive and negative symptoms, and personal and social functioning, were examined. In addition, several aspects of cognition were assessed using neurocognitive assessments such as the Trail Making Test (TMT), Stroop test, and Wisconsin Card Sorting Test (WCST). After adjusting for age differences between groups, the final analysis included data from 42 participants in the community-based group and 33 participants in the hospital-based group. Results: Hospital-based group participants completed Stroop-W more rapidly, excelled in Rey-Osterrieth Complex Figure Test recall and recognition, and incurred fewer TMT Part B (TMT-B) and Stroop-C errors. Additionally, they outperformed in WCST total, non-persistent errors, and categories completed. Contrastingly, community-based group participants showed superior outcomes in WCST persistent responses and errors, suggesting specific neurocognitive strengths. Conclusion We found differences in neurocognitive characteristics between the two groups. These differences were consistent across a range of cognitive domains, including attention, visual discrimination, memory, and executive functioning. Further large-scale study is needed to generalize cognitive characteristics across treatment modalities.

Weiss-Kruszka syndrome (WSKA), caused by heterozygous loss-of-function variants in ZNF462 gene, is a recently described and extremely rare genetic disorder. The main phenotypes include characteristic craniofacial features, ptosis, dysgenesis of the corpus callosum, and neurodevelopmental impairment. We report the first Korean boy with molecularly confirmed WSKA presenting with an atypical manifestation. A 16-year-old boy with a history of bilateral ptosis surgery presented with short stature (−3.49 standard deviation score) and delayed puberty. The patient showed characteristic craniofacial features including an inverted triangular-shaped head, exaggerated Cupid's bow, arched eyebrows, down-slanting palpebral fissures, and poorly expressive face. He had a mild degree of intellectual disability and mild hypotonia. Endocrine studies in the patient demonstrated complete growth hormone deficiency (GHD) associated with empty sella syndrome (ESS), based on a magnetic resonance imaging study for the brain that showed a flattened pituitary gland and cerebrospinal fluid space herniated into the sella turcica. To identify the genetic cause, we performed whole exome sequencing (WES). Through WES, a novel de novo heterozygous nonsense variant, c.4185del; p.(Met1396Ter) in ZNF462 was identified. This is the first case of WSKA accompanied by primary ESS associated with GHD. More clinical and functional studies are needed to elucidate this association.

Objective: This study aimed to introduce a 4-week long fully immersive virtual reality-based cognitive training (VRCT) program that could be applied for both a cognitively normal elderly population and patients with mild cognitive impairment (MCI). In addition, we attempted to investigate the neuropsychological effects of the VRCT program in each group. Methods: A total of 56 participants, 31 in the MCI group and 25 in the cognitively normal elderly group, underwent eight sessions of VRCT for 4 weeks. In order to evaluate the effects of the VRCT, the Korean version of the Consortium to Establish a Registry for Alzheimer’s Disease Assessment Packet was administered before and after the program. The program’ s safety was assessed using a simulator sickness questionnaire (SSQ), and availability was assessed using the presence questionnaire. Results: After the eighth session of the VRCT program, cognitive improvement was observed in the ability to learn new information, visuospatial constructional ability, and frontal lobe function in both groups. At the baseline evaluation, based on the SSQ, the MCI group complained of disorientation and nausea significantly more than the cognitively normal elderly group did. However, both groups showed a reduction in discomfort as the VRCT program progressed. Conclusion We conclude that our VRCT program helps improve cognition in both the MCI group and cognitively normal elderly group. Therefore, the VRCT is expected to help improve cognitive function in elderly populations with and without MCI.

Objectives: Adolescent suicide is a serious national issue in Korea. Recently, life satisfaction has been recognized as a major factor related to this issue. The main purpose of this study was to identify the domains of life satisfaction that affect suicidal behavior in adolescence. Methods: Data were collected from eight middle schools in Incheon, Korea. A total of 1297 students answered questions regarding their demographic characteristics, happiness, self-related life satisfaction domains (appearance, leisure time, physical health, and mental health), depressive symptoms, and suicidal behavior. Results: In the Spearman correlation analysis, female sex, perceived socioeconomic status (SES), happiness, and all four self-related satisfaction scores showed significant correlations with depression and suicidality. Multivariate regression analysis suggested that suicidality was significantly affected by perceived SES, satisfaction with appearance, mental health satisfaction, and depression. Finally, depression was identified as a partial mediator of the association between mental health satisfaction and suicidality, and a complete mediator of the association between female sex and suicidality. Conclusion Perceived SES, satisfaction with appearance, and mental health satisfaction significantly affected students’ suicidality, with or without the effect of depression. Health authorities, educators, and family members must be aware of this to identify adolescents at suicide risk earlier.
