A total of 421 nurses were selected from 10 Grade secondary public hospitals in Shanghai, China. The 12-item General Health Questionnaire (GHQ-12) was used to assess mental health status. Additionally, psychological flexibility and well-being were assessed using the Chinese version of Personalized Psychological Flexibility Index and Chinese version of the 5-item WHO Well-Being Index, respectively. Correlation analysis showed that psychological flexibility was positively associated with well-being (r = 0.220, p < 0.05) and negatively correlated with mental health issues (r = ‒0.225, p < 0.05). Night shift frequency was linked to mental health issues (r = 0.276, p < 0.05) and lower psychological flexibility (r = ‒0.165, p < 0.05). Structural equation modeling demonstrated that age had direct positive effects on psychological flexibility (β = 0.130) and mental health (β = 0.541), while night shift frequency directly worsened mental health (β = 0.618) and reduced psychological flexibility (β = ‒0.198). Psychological flexibility significantly influenced both mental health (β = ‒0.674) and well-being (β = 0.418), with indirect effects on well-being (β = 0.268). Mental health was the strongest predictor of well-being (β = 0.718). These findings highlight the importance of psychological flexibility, night shifts and age in nurses' mental health well-being, though the study's cross-sectional design limits causal inferences.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144309593","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We searched Pubmed and Embase in English and included 76 articles following PRISMA guidelines. Twenty-four-hour Blood Pressure Measurement (24 h ABPM) was the most popular method for assessing chronobiological changes of autonomic function in PD. Reverse blood pressure (BP) dipping, i.e. increase in nighttime systolic BP, was a common finding in PD regardless of disease stage. Most studies using 24 h ambulatory electrocardiogram (24 h ECG) recording or night polysomnography showed attenuated heart rate variability (HRV) in PD patients during both daytime and nighttime. This reduction of HRV seems to occur early in the disease course and to be more profound in more severe PD. Only a few studies used scales and/or diaries or wearable technology for assessing autonomic function in PD. Long-term monitoring methods, such as 24-h ECG and 24-h ABPM, along with advancements in wearable multisensory devices, offer promising tools for continuously tracking fluctuations of autonomic function over extended periods. These approaches provide more comprehensive insights into the autonomic dysregulation and its management in PD.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-16"},"PeriodicalIF":2.2,"publicationDate":"2025-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144257483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigated the relationship between chronotype (morning, intermediate, evening) and CS severity in NSLBP patients, and whether chronotype is associated with pain intensity and disability. A total of 131 patients (aged 18-65) were assessed using the Morningness-Eveningness Questionnaire (MEQ), Central Sensitization Inventory (CSI), Pain Catastrophizing Scale (PCS), Beck Depression Inventory (BDI), Pittsburgh Sleep Quality Index (PSQI), Visual Analogue Scale (VAS), and Roland-Morris Disability Questionnaire (RMDQ). Three-way ANCOVA (controlling for age, gender, and occupation) revealed that evening-type individuals had significantly higher CSI, PCS, BDI, PSQI, and RMDQ scores (all p < 0.05). Hierarchical regression analysis showed that evening chronotype (β = 0.193, p = 0.004), pain catastrophizing (β = 0.508, p < 0.001), and depressive symptoms (β = 0.435, p < 0.001) were independent predictors of CS severity. These findings suggest that eveningness is associated with more severe central sensitization and adverse psychosocial outcomes in NSLBP.

Caregivers reported sleep patterns using daily activity logs, and behavioral problems were assessed using the Child Behavior Checklist 1½-5. Main sleep measures included total sleep time and weekly standard deviations of bedtime, wake time, and total sleep time, reflecting sleep IIV. Logistic regression analyses adjusted for confounding factors (e.g. child age, birth order, maternal age at birth) indicated that higher IIV in bedtime was significantly associated with increased internalizing problems, while greater IIV in total sleep time was linked to externalizing problems. Both indicators of IIV were also associated with overall behavioral problems, independent of average nighttime sleep duration. These findings underscore the relevance of consistent sleep-wake rhythms for emotional and behavioral stability in early childhood and indicate that addressing sleep IIV could support efforts to foster healthier behavioral development.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144224546","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examines whether such geomagnetic fluctuations can entrain locomotor activity rhythms in the blind Mexican cavefish (Astyanax mexicanus), a species with reduced circadian regulation due to life in perpetual darkness. Fish were exposed to artificially altered geomagnetic variations with extended (27 h) or shortened (21 h) periods, while control groups experienced natural diurnal fluctuations. Locomotor activity was continuously recorded and analyzed using periodograms. The results indicate that slow geomagnetic fluctuations did not entrain locomotor rhythms in A. mexicanus. Instead, significant individual variability was observed, with some fish displaying rhythmicity, while others did not. Notably, rhythmic individuals exhibited lower average swimming speeds than arrhythmic ones. Arrhythmic individuals were more common among larger fish. These findings suggest that the circadian regulation reduction in A. mexicanus prevents possible synchronization with weak magnetic cues. Furthermore, the observed correlation between locomotor rhythmicity, body size, and swimming speed highlights potential physiological or metabolic differences underlying inter-individual variability.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-8"},"PeriodicalIF":2.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Circadian preferences (CP) emerge as one of the possible mediators underlying this relationship. Previous studies have focused on clinical samples, employed cross-sectional designs and neglected emerging adulthood stage. This study aimed to explore causal relationships using two-wave longitudinal data. The final sample included 272 students from the University of Zagreb (79% female), aged between 18 and 25 years (M = 20.08, SD = 1.14). The Cross-Lagged Panel Model (CLPM) with mediation was employed to test the bidirectional link between sleep quality and depressive symptoms, considering the mediating effect of CP. According to the results, the relationship between sleep quality and depressive symptoms is reciprocal. The effect size indicates that sleep quality has a statistically significant predictive effect on depressive symptoms over time, and vice versa. Mediation analysis revealed that CP did not significantly mediate the relationship between sleep quality and depressive symptoms. CP significantly influenced sleep quality but did not independently contribute to depressive symptoms, suggesting that other mechanisms may be involved in this relationship, such as genetic influences or emotional regulation. The bidirectional relationship between sleep quality and depressive symptoms has significant implications for effective treatment and the prevention of future issues and poorer prognoses. Environmental interventions designed to enhance sleep quality may prevent the onset of depression or reduce existing depressive symptoms. To maximize the effectiveness of these interventions, further research into the mediators of this relationship is essential.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-12"},"PeriodicalIF":2.2,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Majority of the students fall in intermediate chronotype in our study with the evening chronotypes having poor sleep quality, leading to low cognitive function that in turn causes periods of anxiety and stress which was reflected in salivary cortisol levels. The evening chronotypes also exhibited lower nocturnal melatonin levels compared to morning types and had difficulty in falling to sleep with elevated oral temperatures. Elevated BMI status and frequencies of fast-food intake were also high in evening chronotypes, which may increase the chances of obesity in them and also prone to hyperglycemia as indicated by higher fasting blood sugar and salivary amylase levels. The metabolic profiles were also altered in late chronotypes as evidenced by low thyroid hormone profiles and higher triglyceride levels. Our study reports intermediate chronotypes along with evening types are at the risk of developing sleep deprived disorders in the future, and it is important that researchers should develop tailored sleep interventions that consider demographic, psychological, and socio-behavioral factors contributing to poor sleep quality, excessive daytime sleepiness, and short sleep duration among students.","PeriodicalId":10294,"journal":{"name":"Chronobiology International","volume":" ","pages":"1-24"},"PeriodicalIF":2.2,"publicationDate":"2025-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144198388","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In an in silico study, a model of sleep-wake regulation was applied to show that the difference between earlier and later weekday risers in weekday risetime is equal to the sum of differences between them in sleep loss and sleep phase advance that can be measured as their differences in weekend-weekday gap in risetime and in weekend risetimes, respectively. Such differences in sleep loss and sleep phase advance were estimated from bed- and risetimes self-reported for weekdays and weekends by 4940 university students and lecturers subdivided into subsamples with different weekday risetimes and chronotypes.
