Summary: The study aims to develop a Chinese version of the C-CMAI-SF and examine its validity and reliability. The results show that the C-CMAI-SF is a valid and reliable instrument for evaluating agitated behaviors in people with dementia, and it can be easily used in busy clinical settings to identify and evaluate such behaviors.

Summary: This study aimed to explore the construct validity of the German version of the Cohen-Mansfield Agitation Inventory-Short Form (CMAI-SF). The results showed that the CMAI-SF had good internal consistency in total score and factors, and demonstrated convergent validity and discriminant validity with other related measures. These findings provide preliminary evidence that the CMAI-SF can be used instead of the CMAI in future trials to reduce time, costs, and burden.

Summary: Psychomotor slowing is a key feature of depressive disorders. A novel meta-analysis on actigraphically measured slowing in depression was conducted, and the results showed that patients with depression have lower activity levels. This study provides important evidence for using actigraphy to assess and stage depressive disorders.

Summary: This study investigated the association between light exposure in daily life and circadian activity rhythms in patients with bipolar disorder. The results showed that daytime light exposure was positively associated with circadian activity rhythms, while nighttime light exposure was negatively associated.

Summary: This study used latent profile analysis (LPA) and assessments of activity, sleep, and circadian characteristics to classify bipolar disorder type I (BDI) subjects into high and low chronobiological disturbance sub-groups. Circadian variables were found to be the distinguishing factors between the sub-groups. Future research should further explore the role of circadian characteristics in defining sub-phenotypes of bipolar disorder.

Summary: The study introduced a novel method using machine learning algorithm for circadian rhythm analysis of wearable device data, which effectively characterized sleep-activity rhythms and the association between daily rhythm formation and early childhood motor development.

Summary: The study revealed both harmful and protective effects of DST transitions on the risk of out-of-hospital cardiac arrest. Following the spring transition, there was an immediate increase in risk on the day of transition, while the autumn transition showed a significant reduction in incidence, especially by the end of the transitional week. Strategies to mitigate these effects should be considered for vulnerable populations.

Summary: This study tested the internal consistency, reliability, and validity of the short-form CMAI in nursing home residents with cognitive impairment and confirmed its invariance across gender. The findings provide evidence for assessing agitation and gender differences in nursing home populations.

Summary: The study analyzed the factor structure of actigraphy-derived sleep measures in older adults and identified five factors (Timing, Efficiency, Duration, Sleepiness/Wakefulness, and Regularity) in both sexes. Confirmatory factor analyses confirmed the one-factor structure for each factor as well as the five-factor structure. The findings provide insights for selecting sleep health domains, representative measures, and potential targets for behavioral interventions.

Summary: Evening light exposure significantly affects sleep in patients with bipolar disorder, with higher white-light illuminance associated with lower sleep efficiency, prolonged sleep-onset latency, and longer wake after sleep onset. Further investigation is needed to understand the effects of various light wavelengths on sleep in bipolar disorder.

Summary: Animal-assisted interventions, specifically dog interventions, have shown to be effective in reducing agitation in older patients with dementia. Stopping the intervention resulted in an increase in agitation, while reintroducing it led to a decrease. Further studies are needed to standardize practices for optimal care.

Summary: This meta-analysis study indicates that administration of dexmedetomidine can reduce the risk of postoperative cognitive and behavioral dysfunction in adult patients undergoing general anesthesia for non-cardiac surgery, regardless of the anesthesia technique used.
