Summary: In competitive sociocultural environments, Korean workers tend to shorten their weekday sleep duration. This study aimed to investigate the relationship between weekend catch-up sleep (CUS) and dyslipidemia among South Korean workers. The analysis used data from the 8th Korea National Health and Nutrition Examination Survey (KNHANES), covering 4,085 participants. After adjusting for various factors, a negative association was observed between weekend CUS and dyslipidemia in male workers. Workers with 7-8 hours of total sleep duration, night workers, and white-collar workers who engaged in CUS were at lower risk of dyslipidemia compared to the non-CUS group.

Summary: Short weekday sleep and insufficient weekend catch-up sleep are independently associated with an increased risk for metabolic derangements, except hypertension. Individuals who do not make up sleep on the weekend are more likely to be obese and have type 2 diabetes or hypercholesterolemia.

Summary: Eveningness preference and insufficient weekday sleep duration were associated with an increased risk for depression, while weekend catch-up sleep durations >= 2 hr reduced the risk for depression. Factors like female gender, underweight or obese body weight, short weekday sleep durations, excessive daytime sleepiness, and perceived insufficiency of sleep were linked to a higher risk of depression among late adolescents.

Summary: This study addresses important research gaps by examining the relationship between sleep duration and adolescent health in South Korea. The findings suggest that the association between short sleep duration and health is partly confounded by unobserved individual heterogeneity, and weekend catch-up sleep has limited moderating effects on this association.

Summary: In Korean adolescents, there is a discrepancy in sleep duration between weekdays and weekends, and they may compensate for weekday sleep debt by extending their sleep on weekends. The study found that total sleep duration and weekend sleep duration were negatively associated with body mass index z-score. Increasing weekend sleep duration and sleep extension on weekends decreased the relative risk of overweight/obesity. However, further prospective studies are needed to establish the causality between extended weekend sleep and obesity.

Summary: In this study, we used resting-state functional MRI to identify structural and functional changes in healthy adults with catch-up sleep (CUS). Our findings suggest that deficits in reward processing may underlie the motivation for taking CUS, as the CUS group had a higher reward-seeking tendency and increased grey matter volume and functional connectivity in regions responsible for the reward network.

Summary: This study aimed to evaluate whether the relationship between weekday sleep duration and prevalence of metabolic syndrome (MetS) differs according to weekend catch-up sleep (CUS) in Korean adults. The study found that individuals with shorter weekday sleep duration and maximum CUS of 1 hour had a higher odds of developing MetS, while those with longer weekday sleep and maximum CUS of 2 hours also had a higher odds of developing MetS. Even among individuals with no CUS or CUS of 2 hours or more, the odds of developing MetS were higher than the reference group, even with adequate weekday sleep duration (7-9 hours).

Summary: This cross-sectional study aimed to evaluate the association between weekday sleep duration, weekend catch-up sleep, obstructive sleep apnea risk, and handgrip strength. The study analyzed data from 3678 Korean adults aged 40 to 80 years and found that adequate weekday sleep duration, weekend catch-up sleep, and low obstructive sleep apnea risk were individually and collectively associated with high handgrip strength.

Summary: The study found that weekend sleep was unable to compensate for sleep lost due to early wakeups on weekdays, contrary to the widely held belief. The lockdown during the COVID-19 pandemic provided an opportunity to validate the predictive power of sleep-wake regulating models, highlighting the need to rethink the concept of catch-up sleep on weekends.

Summary: This study investigated the volume and T1 value differences of the habenula (Hb) between patients with major depressive disorder (MDD) and healthy controls using high-resolution 7-T MR imaging data. The results showed that MDD patients had a smaller right Hb volume compared to healthy controls, with no significant volume difference in the left Hb between groups. Additionally, in the MDD group, the right Hb exhibited both smaller volume and lower T1 value compared to the left Hb.

Summary: Symptoms of bipolar disorder include changes in mood, activity, energy, sleep, and appetite, with circadian rhythm disturbance considered a biological feature underlying BD. Research has found associations between the circadian system and mood regulation, but circadian disruption is not specific to BD and is present across various psychiatric disorders. Future studies on circadian rhythms and its role in BD should carefully define associations and integrate across levels of analysis for more comprehensive insights.

Summary: Through postmortem gene expression analysis, 251 differentially expressed genes (DEGs) were identified in the Hb tissue of suicides compared to Hb tissues from neurotypical individuals. Subsequent bioinformatic analyses using single-cell transcriptome data from the mouse Hb revealed that a subset of endothelial cell-enriched genes and their putative upstream transcriptional regulators were significantly affected in suicides. Despite being based on a limited number of samples, the study suggests a potential association of endothelial dysfunction in the Hb with depression and suicidal behavior.

Summary: This study used psychological autopsies to investigate factors related to suicide in Incheon, South Korea. The findings showed that 87% of suicide victims had mental health conditions before their death, but only 15.2% received treatment or counseling. Warning signs were present in most individuals who died by suicide, but only 19.6% of survivors noticed them. Mental health concerns were also identified in over half of the families of the deceased. Intensive and continuous treatment for psychiatric conditions, prompt recognition of suicide warning signs, and care for the mental health of family members are crucial for suicide prevention.

Summary: This study compared the mean PR and mean BP between OSA and SS patients during a 24-hour period and investigated the correlation between AHI, PR, and BP in SRBD patients with and without hypertension, DM, and CVDs. The results showed significantly higher mean PRs in the OSA group compared to the SS group, but no significant difference in mean BP. Correlation analysis showed a significant correlation between AHI and PR in participants without hypertension, DM, or CVDs but not in participants with these conditions.

Summary: This study aims to predict impending mood episode recurrences using digital phenotypes related to circadian rhythm obtained from wearable devices and smartphones. The results show that using digital phenotypes can accurately predict the occurrence of mood episodes, with circadian rhythm misalignment being the most important predictor. This finding suggests that monitoring circadian rhythm using digital devices can be useful in preventing and treating mood disorders.

Summary: This study aimed to examine the engagement and theoretical drivers of camouflaging behavior in the general population. The findings revealed a similar dimensional structure of camouflaging behavior in the general population compared to previous studies on autism. Social motivational factors, such as social comparison, public self-consciousness, internalized social stigma, and social anxiety, were identified as significant predictors of camouflaging behavior. These findings highlight the shared social coping experience of camouflaging in the general population, including autistic individuals.

American women scored higher on the Baby-PAWS items than Dutch women. These results highlight cross-cultural differences in perinatal mental health and stress the importance of examining instrument structure of context-dependent constructs.

Summary: This study found differences between patients with gambling disorder (GD) with and without self-reported ADHD symptoms in terms of psychopathology, personality, and treatment outcomes. Patients with self-reported ADHD symptoms were more severe in their GD and experienced more severe relapses following treatment. Therefore, more vigilant follow-up and interventions are needed for patients with this comorbidity.
