Summary: The effects of delaying main sleep on sleep quality and architecture vary between chronotypes. Early chronotypes experience less total sleep with delayed sleep, while intermediate and late chronotypes have more REM sleep. Circadian processes elevate wakefulness for all chronotypes in the later stages of delayed sleep.

Summary: A cross-sectional study was conducted to examine the relationship between chronotype, sleeping, and eating patterns. The study found no significant differences in sleep habits among different chronotypes. However, evening chronotypes tended to consume meals later in the day compared to other chronotypes, and morning chronotypes reported a better diet quality.

Summary: The study found that asthma patients experience worsened lung function and exacerbation of symptoms at night, often masked by sleep. Asthma patients exhibit significant circadian rhythms throughout the day and are more likely to use bronchodilators during the night.

Summary: In this cross-sectional study, the association between mothers' and infants' chronotype, sleep, mental health, socioeconomic status, and infant development was investigated. The results showed that infants' sleep phases were influenced by their mothers' chronotype, and sleep disorders were correlated with atypical development. Mothers of infants with sleep disorders or discordant chronotypes had worse sleep quality and poorer mental health. These findings highlight the importance of sleep quality and chronotype in mothers' mental health and infant development.

Summary: Children and adolescents with an evening chronotype are more prone to incorrect eating behaviors and are more likely to suffer from overweight/obesity. The association between chronotype, eating disorders, and obesity should take into account environmental and lifestyle factors.

Summary: Sleep disorders appear to be more common in women, while sex-related differences exist for dreams and nightmares. Differences related to dreams include dream content, self-reported perspective, dream sharing, lucid dreaming, and daydreaming. Nightmares are more frequent in women and are often associated with sleep disorders and psychiatric disorders like depression and anxiety.

Summary: Human activities follow daily, weekly, and seasonal rhythms. This study introduces a data-driven method to characterize individuals based on their daily and weekly rhythms of activity and behavior, rather than just focusing on the timing of their sleeping periods. Using smartphone data, the researchers identified four temporal components of activity: morning, night, evening, and noon. The weights on these components correlated strongly with sleep and wake-up times.

Summary: Chronotype, an indicator of circadian rhythmicity, was investigated in post-menopausal women with obesity. The study found that intermediate chronotype was more prevalent in pre-menopausal women compared to post-menopausal women, and evening chronotype was associated with a higher risk of type 2 diabetes in both pre- and post-menopausal women with obesity. This suggests the importance of considering chronotype assessment in the management of obesity in post-menopausal women.

Summary: Excessive fatness and circadian disruption affect physiology and hormones, such as cortisol, in female mice. Feeding a high fat diet to mice resulted in increased daytime feeding, weight gain, body fat percentage, hair corticosterone levels, and disrupted fecal corticosterone rhythms.

Summary: The study aimed to examine the effect of sleep timing intervention on sleep quality, attention, and sleepiness at work among night shift workers with shift work disorder. The results showed that participants had longer sleep duration, higher sleep quality, shorter reaction times, and fewer lapses during evening sleep schedules compared to morning sleep schedules. The differences between sleep schedules were most prominent among those with late chronotypes.

Summary: This study aimed to investigate the circadian rhythms and sleep-wake behavior associated with MDD and high risk for MDD among adolescents. The results showed that adolescents with MDD exhibited more severe insomnia, shorter sleep duration, higher social jetlag, and higher exposure to artificial light at night compared to other groups. The HR group also showed similar problems. Therefore, preventive strategies should focus on sleep issues, and actimetry-based parameters may be promising tools for assessing depression in adolescence.

Summary: In this study, the researchers aimed to develop algorithms for accurately detecting nonwear in wrist-actimetry data and identify useful variables in the process. They compared different solutions for detecting off-wrist and found that automated strategies were similarly effective to visual inspection but faster and less reliant on raters' attention/experience. However, all methods had limitations in detecting short intervals.

Summary: The degree of loss of control over eating is more important than the size of binge episodes in predicting psychological and behavioral outcomes in individuals with binge eating disorder (BED). While greater loss of control is associated with more eating psychopathology and symptoms, larger binge size is linked to higher weight concern and lower quality of life, particularly in terms of general and social aspects.

Summary: This study investigated the prevalence of post-traumatic stress disorder (PTSD) and sleep quality among victims and rescue workers of the third deadliest nightclub fire in the world. The results showed high rates of PTSD and poor sleep quality, with daytime dysfunction strongly associated with PTSD. Factors such as shift work, female sex, and previous psychiatric disease were also associated with PTSD.

Summary: This study aimed to evaluate the potential predictors of adequate treatment response in MDD, including sleep, levels of 6-sulfatoxymelatonin, and other circadian parameters derived from actimetry. The results showed that increased activity levels, earlier peak of activity, and lower intradaily variability of light exposure were associated with early antidepressant response. Sleep parameters and 6-sulfatoxymelatonin levels did not predict treatment response.

Summary: This study examined the relationship between eating behaviors and weight loss following bariatric surgery. The results showed that subjective binge episodes before surgery predicted greater weight loss over the first 12 postoperative months. Postoperative disinhibition, hunger, night eating symptoms, objective binge episodes, global disordered eating attitudes and behaviors, and number of snacks per day were associated with smaller weight loss over 12 months.
