This meta-analysis aimed to consolidate existing data from randomised controlled trials on hypoplastic left heart syndrome.

Hypoplastic left heart syndrome specific randomised controlled trials published between January 2005 and September 2021 in MEDLINE, EMBASE, and Cochrane databases were included. Regardless of clinical outcomes, we included all randomised controlled trials about hypoplastic left heart syndrome and categorised them according to their results. Two reviewers independently assessed for eligibility, relevance, and data extraction. The primary outcome was mortality after Norwood surgery. Study quality and heterogeneity were assessed. A random-effects model was used for analysis.

Of the 33 included randomised controlled trials, 21 compared right ventricle-to-pulmonary artery shunt and modified Blalock–Taussig-Thomas shunt during the Norwood procedure, and 12 regarded medication, surgical strategy, cardiopulmonary bypass tactics, and ICU management. Survival rates up to 1 year were superior in the right ventricle-to-pulmonary artery shunt group; this difference began to disappear at 3 years and remained unchanged until 6 years. The right ventricle-to-pulmonary artery shunt group had a significantly higher reintervention rate from the interstage to the 6-year follow-up period. Right ventricular function was better in the modified Blalock–Taussig-Thomas shunt group 1–3 years after the Norwood procedure, but its superiority diminished in the 6-year follow-up. Randomised controlled trials regarding medical treatment, surgical strategy during cardiopulmonary bypass, and ICU management yielded insignificant results.

Although right ventricle-to-pulmonary artery shunt appeared to be superior in the early period, the two shunts applied during the Norwood procedure demonstrated comparable long-term prognosis despite high reintervention rates in right ventricle-to-pulmonary artery shunt due to pulmonary artery stenosis. For medical/perioperative management of hypoplastic left heart syndrome, further randomised controlled trials are needed to deliver specific evidence-based recommendations.

With the increase of older adult population, late life depression is emerging as a major problem in many countries as it significantly deteriorates function and quality of life in older adults. Late life depression is a multidimensional disease that requires intervention in biopsychosocial perspective. Recent reduction in family size and rapid simplification of generations are making this decrease more dramatic. Thus, single older households are becoming general type of household in late life, emphasizing the importance of social engagement in late life depression

the purpose of this study is to assess the correlation between the frequency of face-to-face and non-face-to-face contact with non-cohabitating adult children and late life depression after the COVID-19 pandemic. Additionally, we hypothesized 10 possible moderators and evaluated the moderation effect of each moderator on the correlation. By identifying groups of older adults that are more affected by contact with their children, the understanding of the relationship between late life depression and family contact in older adults might provide insights to set intervention targets in the community.

Older adults who completed the Living Profiles of Older People Survey in Korea were included. In total, 7,573 participants were analyzed by measuring their contact frequency and depression symptoms. Regression analysis was done adjusting covariates. Process macro was used to verify the moderating effects of variables.

Multivariable logistic regression analysis showed that both infrequent face-to-face (OR=1.87, 95% CI=1.56-2.23) and non-face-to-face contact (OR=1.22, 95% CI=1.03-1.44) with non-cohabitating adult children group was associated with higher risk of late life depression compared to a frequent contact group. Further linear regression analysis, which viewed depressive symptoms as SGDS-K score, indicated consistent results in face-to-face and non-face-to-face contact (estimate=0.468, standard error [SE]=0.091, p<0.001 and estimate=0.262, standard error [SE]=0.079, p<0.001, respectively). Finally, using moderation analysis, association with late life depression and frequency of face-to-face contact was moderated by age, quartiles of household income, number of chronic diseases, frequency of physical activity, existence of spouse, and nutritional status (NSI) whether effect of frequency of non-face-to-face contact on late life depression was increased by participation in social activity, frequent physical activity, and good cognitive function (MMSE-DS score)(p for interaction<0.05).

Frequent contact of non-cohabitating children lowers the risk of later life depression. Several variables were found significant in moderating contact frequency-depression symptoms.

Existing digital mental health interventions are mainly focused on the symptoms of specific mental disorders such as depression and anxiety. However, digital mental health interventions aiming enhancement of mental health in the general population are rare. Considering that the psychological discomfort of the general public is more complex and subtle, interventions focusing on maladaptive personality and interpersonal schema rather than symptoms per se can be an alternative.

To this end, concise tools for measuring the core personality and interpersonal patterns known to cause psychological discomfort among potential users of digital mental health interventions are essential. For this purpose, the Schema Scale was developed and our study aims to validate and confirm psychometric properties of the scale.

This cross-sectional study was carried out between July and August 2022. Participants were 234 adults aged between 19 to 39 who completed an online survey including the Schema Scale and other 15 questionnaires. Exploratory factor analysis were conducted to construct the factorial structure model.

Exploratory factor analysis showed a five-factor structure with a total variance of 57%; factor 1 consisted of lack of belongingness and poor social skills, factor 2 of lack of patience hot-tempered coping style, factor 3 of maladaptive perfectionism, factor 4 of self-sacrifice and lack of self-confidence and factor 5 of items representing pessimistic and anxious mindset. Internal consistency of each factor was good(Cronbach’s alpha=0.712~0.882), and correlations with existing measures were significant.

The five personality Schema Scale appears to be a short(total 35 items) and a valid tool for measuring five essential personality and interpersonal patterns for adults aged 20~30 years. This tool has been developed for online use and therefore has the advantage of being easily accessible. Most importantly, based on the results of the Schema Scale, the individualized digital interventions can be recommended that targets maladaptive psychological patterns.

Olanzapine (OLA) is a common first-prescribed antipsychotic and has shown favorable efficacy in acutely exacerbated patients with schizophrenia. The mixed receptor activity of OLA and its greater affinity for serotonin 5-HT2A rather than dopamine D2 receptors are similar to those of clozapine. Pharmacokinetically, OLA is metabolized mainly by hepatic cytochrome enzyme P450 1A2 (CYP1A2). Because risks of antipsychotic polypharmacy include increased drug-drug interactions, pharmacokinetic considerations are important for selection of antipsychotics to be combined. Due to its pharmacological characteristics, amisulpride (AMI), another atypical antipsychotic with proven efficacy, is a promising adjuvant agent of special interest. AMI is unlikely to interact with other drugs due to the low plasma protein binding and metabolism and does not affect the activity of the CYP system. Furthermore, AMI is highly selective for dopamine D2/D3 receptors; has minimal or no affinity for D1, D4, or D5 receptors. Despite the potential benefits of the combination of OLA and AMI, only a few open-label studies have been conducted, and no randomized clinical trial has been performed to date to examine the efficacy and tolerability of the combination. Hence, the goals of this study were to test the hypothesis that AMI augmentation would improve psychotic symptoms and be well tolerated in schizophrenic patients who showed poor response to OLA monotherapy.

The purpose of this study was to compare the efficacy and tolerability of continued olanzapine (OLA) versus amisulpride (AMI) augmentation in schizophrenic patients with poor response to OLA monotherapy.

The present 4-week, randomized, rater-blinded study included 25 patients with schizophrenia who were partially or completely unresponsive to treatment with OLA monotherapy. Eligible subjects were randomly assigned at a 1:1 ratio to continuation of OLA monotherapy (OLA group) or OLA with AMI augmentation (AMI group). Efficacy was primarily evaluated using the Positive and Negative Syndrome Scale (PANSS) at baseline and at 1, 2, and 4 weeks.

The changes in PANSS total score and PANSS-positive subscale score were significantly different (p < 0.05) between the OLA and AMI groups. The differences between the two groups in PANSS-negative subscale, PANSS-general subscale, Brief Psychiatric Rating Scale, and Clinical Global Impression-Severity (CGI-S) scale scores were not statistically significant.

AMI augmentation could be an effective strategy for patients with schizophrenia who show inadequate early response to OLA monotherapy.

Studies have reported mixed findings regarding the impact of the coronavirus disease 2019 (COVID-19) pandemic on pregnant women and birth outcomes. This study used a quasi-experimental design to account for potential confounding by sociodemographic characteristics.

Data were drawn from 16 prenatal cohorts participating in the Environmental influences on Child Health Outcomes (ECHO) program. Women exposed to the pandemic (delivered between 12 March 2020 and 30 May 2021) (n = 501) were propensity-score matched on maternal age, race and ethnicity, and child assigned sex at birth with 501 women who delivered before 11 March 2020. Participants reported on perceived stress, depressive symptoms, sedentary behavior, and emotional support during pregnancy. Infant gestational age (GA) at birth and birthweight were gathered from medical record abstraction or maternal report.

After adjusting for propensity matching and covariates (maternal education, public assistance, employment status, prepregnancy body mass index), results showed a small effect of pandemic exposure on shorter GA at birth, but no effect on birthweight adjusted for GA. Women who were pregnant during the pandemic reported higher levels of prenatal stress and depressive symptoms, but neither mediated the association between pandemic exposure and GA. Sedentary behavior and emotional support were each associated with prenatal stress and depressive symptoms in opposite directions, but no moderation effects were revealed.

There was no strong evidence for an association between pandemic exposure and adverse birth outcomes. Furthermore, results highlight the importance of reducing maternal sedentary behavior and encouraging emotional support for optimizing maternal health regardless of pandemic conditions.

Obsessive-compulsive disorder (OCD) and schizophrenia are often reported as co-morbid conditions. However, the evidence of an association between OCD and the risk of schizophrenia is limited. This study investigated the risk of schizophrenia in patients newly diagnosed with OCD using a nationally representative sample cohort in South Korea.

Data were obtained from the 2002–2013 Korean National Health Insurance Service-National Sample Cohort of the National Health Insurance Service. Using propensity score matching, 2509 patients with OCD and a control group of 7527 patients were included in the analysis. Chi-squared tests were used to investigate and compare the general characteristics of the study population. The risk of schizophrenia was analysed using the Cox proportional hazard model.

The incidence rate was 45.79/10 000 person-year for patients with OCD and 4.19/10 000 person-year for patients without OCD. Patients with OCD had a higher risk of schizophrenia compared to the control group after adjusting for covariates (hazard ratio = 10.46, 95% confidence interval = 6.07–18.00).

This study identified an association between the diagnosis of OCD and the risk of schizophrenia in a South Korean national representative cohort. Further research using a prospective design to clarify the causality of OCD in schizophrenia in a controlled environment should be conducted to validate these findings.

Hearing impairment in older adults may affect cognitive function and increase the risk of dementia. Most cognitive tests are delivered auditorily, and individuals with hearing loss may fail to hear verbal instructions. Greater listening difficulty and fatigue in acoustic conditions may impact test performance. This study aimed to examine the effect of decreased audibility on cognitive screening test performance in older adults.

Older adults (n = 63) with different levels of hearing loss completed a standard auditory Mini-Mental State Examination test and a written version of the test.

Individuals with moderate to moderately severe hearing loss (41–70 dB) performed significantly better on the written (24.34 ± 4.90) than on the standard test (22.55 ± 6.25), whereas scores were not impacted for mild hearing loss (less than 40 dB).

Hearing evaluations should be included in cognitive assessment, and test performance should be carefully interpreted in individuals with hearing loss to avoid overestimating cognitive decline.

Direct gaze is the most important mediator of social interaction and communication. Existing studies have evaluated eye movements of patients with schizophrenia by presenting stimuli using photographs or pre-recorded videos, but few directly investigated gaze avoidance in real-world situations.

To investigate the correlation between gaze avoidance and psychopathology in patients with schizophrenia through eye movement measurements in real-life interpersonal situations.

We enrolled 52 clinically stable patients with schizophrenia. Psychopathology was evaluated using the Positive and Negative Syndrome Scale (PANSS), Hamilton Depression Rating Scale, and Hamilton Anxiety Rating Scale. After presenting a visual stimulus, eye movements were measured with Tobii Pro Wearable Glasses 2, and deep learning-based emotional recognition using the residual masking network was used for neutral stimulus verification. Statistical analyses were performed using Pearson’s correlation and regression analyses.

Data of 45 participants with verified stimulus neutrality by deep learning image recognition were used for analysis. The first dwelling time was negatively correlated with the PANSS positive syndrome subscale (p=0.028), general psychopathology subscale (p=0.008), total score (p=0.008), 5-factor positive symptoms (p=0.035), and 5-factor depression/anxiety symptoms (p=0.008). The baseline-area of interest (AOI) pupil diameter change was positively correlated with PANSS 5-factor positive symptom scores (p=0.039). After adjusting for additional variables, the same items had a significant effect on the first dwelling time and baseline-AOI pupil diameter change.

Psychopathology, particularly positive symptoms, was associated with gaze avoidance and pupil diameter in patients with schizophrenia. Evaluating the characteristics of eye movements in patients with schizophrenia will enable better understanding of their symptoms.

Adolescents with major depressive disorder (MDD) often show reduced prefrontal functional connectivity with the subcortical regions than healthy controls (HC) (Tang et al., 2018). However, relatively little is known about longitudinal effects of antidepressant (AD) treatment on resting state functional connectivity (RSFC) in the prefrontal cortex (PFC).

This study aimed to investigate abnormal PFC RSFC in MDD adolescents compared to HC and longitudinal effects of AD on PFC RSFC.

This study included 59 adolescents with MDD and 43 HC. MDD adolescents were treated with escitalopram in an 8 week, open-label trial. The treatment outcome was assessed by Children’s Depression Rating Scale (CDRS-R) and patients showing at least a 40% improvement in CDRS-R scores from baseline to week 8 were defined as “responders”. Functional and T1 images collected before and after treatment were processed using AFNI and Freesurfer. Our seed was the lateral PFC (LPFC, BA46). T-tests and repeated measures ANCOVAs, controlling for age and IQ, were conducted to examine abnormal PFC RSFC and longitudinal effects of AD on LPFC RSFC.

Relative to HC, MDD showed increased LPFC RSFC with the posterior middle temporal gyrus (pMTG) and superior frontal cortex (SFG) involved in attentional networks. Responders showed greater changes in LPFC RSFC with the MTG and SFG after AD treatment compared to non-responders and HC (Figure 1).

Our finding suggests that reduced LPFC RSFC with the pMTG and SFG reflecting decreased attentional network connectivity may serve as a biomarker to predict AD treatment outcome in adolescents with MDD.

Hwa-Byung is characterized by feelings of anger or resent about unreasonable social violence and trauma. Although Prevalence of Hwa-Byung is high in middle-aged, recently Hwa-Byung is occurred in young people. And it is suggested that young Hwa-Byung patients will show different patterns from middle-aged.

The purpose of present study was to qualitatively analyze young Hwa-Byung patients’ experiences of symptoms and psychological characteristics related to antecedent events of Hwa-Byung.

10 women aged 20s were Interviewed using semi-structured questionnaires to in-depth study on their experiences related to Hwa-Byung. The interview data were analyzed using phenomenological approach in order to understand the essence of experiences. In particular, it was analyzed through five steps according to Giorgi (1985). First, by repeatedly reading the material, recurring themes were identified. Second, the meaning units were divided to capture important parts of participants’ statements. Third, similar meaning units were grouped together. Fourth, the determined meaning units were described in psychological term. Finally, research data were integrated and presented according to the described meaning units. Reliability between coders was higher than the minimum reliability coefficient.

In symptoms, two themes and seven sub-themes were emerged. In psychological characteristics, three components and five sub-themes were derived. In particular, the antecedent events of young Hwa-Byung patients were related to vertical social relationships, suggesting that Hwa-Byung need to be understood under social context which make them angry.

Present study revealed the social context of Hwa-Byung by discussing the differences between young and middle-aged patients, and furthermore, differences between Hwa-Byung and depression, PTSD patients.

Hwa-Byung is a cultural-related mental syndrome that reflects the cultural characteristics of Korean in DSM-IV. This syndrome is caused by anger or resentment towards unreasonable social violence and trauma.

The purpose of this study is to revise and validate the ’Hwa-Byung scale’, which can be used to diagnose Hwa-Byung and evaluate the severity of its symptoms.

To begin with, the factors of the Hwa-Byung scale were set based on the previous studies. Additionally, the respective subfactors were generated by the semi-structured interviews with these patients. Based on these factors and previous studies, a 142-item pool was developed and verified by six Oriental Neuropsychiatrists. A pilot study was conducted on 50 patients with Hwa-Byung and the main study for the validation was conducted on 200 Hwa-Byung patients. Item analysis, internal consistency, and exploratory/confirmatory factor analysis were performed. Lastly, this study analyzed the ROC curve to present the diagnostic cut-off score of the scale.

As a result of analyzing the content validity of the item pool, we constructed a preliminary scale. We excluded the inadequate questions from the pilot study results. In the main study, The Hwa-Byung scale showed high internal consistency and its items were suitable for the factor structure. Finally, we suggest an optimal cut-off score of the symptoms sub-scale for screening Hwa-Byung.

Overall, the results of this study indicated the reliability and validity of the Hwa-Byung Scale. Based on these results, we discussed several values and limitations of this study and provided suggestions for further research.

Hwa-Byung is a mental syndrome classified as a “cultural-related syndrome” which reflects the cultural characteristics of Korea in DSM-IV. Hwa-Byung is caused by anger, which is characterized by feelings of anger or resent about unreasonable social violence and trauma. Kwon et al (2008) had developed self-report measure to assess severity of Hwa-Byung but it has several limitations to use in current clinical settings. Therefore, we investigated opinions of experts who have professionality in giving treatment of Hwa-Byung patients in the clinical settings.

The present study aimed to reach consent of oriental neuropsychiatrists’ opinions about the direction of revision of the Hwa-Byung scale.

The Delphi method is a survey method that induces people to freely present their opinions without face-to-face processes and reaches consent through continuous feedback of survey results while ensuring anonymity. The Consensus Panel consists of 16 experts who are Oriental neuropsychiatrists and have experience in diagnosing patients with Hwa-Byung. A total of four surveys were conducted as consensus was reached on the fourth round. Each questionnaire was distributed by mail to a panel of experts and was asked to submit a response after receiving the questionnaire.

The results of the study are as follows. First, common factors for Hwa-Byung include anger, resent/blame, modify memory bias and attention bias for anger events. Second, characteristics of young Hwa-Byung patients include stress caused by social factors and excessive immersion in certain things such as drinking or smoking.

Therefore, when revising the Hwa-Byung scale, it would be necessary to include these factors.
