Summary: Circadian rhythms are physiological systems that repeat with a 24-hour cycle, playing a significant role in maintaining physiological homeostasis and influencing how organisms respond to their environment, disease, stress, and therapeutics. These rhythms affect almost every aspect of human physiology, including drug response, highlighting the importance of considering circadian rhythms in personalized medicine approaches for patient benefit.

Summary: Research indicates that weight loss from early adulthood to middle or old age is significantly associated with a higher risk of suicide death, while weight gain is linked to a lower risk. The increased risk of suicide death among those who experience weight loss remains consistent even after excluding participants with a history of disease or psychological distress.

Summary: This study found that SARS-CoV-2 infection was associated with an increased risk of fatigue and sleep problems. However, results from the negative control analysis suggest that unobserved confounding may be responsible for at least some of the positive association between COVID-19 and psychiatric morbidity.

Summary: This study investigated sleep patterns and intraindividual night-to-night variability in mothers and fathers at 6 months postpartum. The results showed that mothers had more fragmented sleep compared to fathers, with shorter consecutive sleep duration and more nocturnal awakenings. Although there was no difference in self-reported nocturnal sleep duration between mothers and fathers, objective measurement indicated that mothers had significantly longer nocturnal sleep duration. Both parents exhibited high variability in sleep fragmentation across subjective and objective indices.

Summary: The study aimed to explore the relationships between postpartum depression and maternal and infant sleep parameters and investigated the impact of infant feeding method on infant and maternal sleep as well as postpartum depression symptomatology. Data was collected from 61 new mothers and their infants, and the results showed that the scores on the Edinburgh Postnatal Depression Scale and General Sleep Disturbances Scale were consistently correlated with each other, but not with objective measures or subjective reports of sleep. Furthermore, exclusively breastfeeding women were not more likely to suffer from postpartum depression.

Summary: Research shows that obesogenic diets have an impact on anxiety-like behavior in rodents, primarily by reducing time spent in open areas. The effects of obesogenic diets are stronger in males than in females, with no significant impact observed from caloric restriction but potential increase observed from protein restriction. Further studies are needed to determine the underlying mechanisms behind these behavioral changes induced by obesogenic diets.

Summary: This study aimed to examine the prevalence of insomnia according to DSM-5 criteria and differences in sleep duration across various mental and physical disorders. Results showed that insomnia and short sleep duration are strongly associated with a range of different disorders and conditions, with insomnia being most strongly linked to mental disorders and physical conditions with psychological or psychosomatic properties.

Summary: The study aims to investigate the sleep disparities between gender minority adolescents (GMAs) and non-GMAs, with findings showing that GMAs are more likely to report inadequate sleep, shorter sleep duration, and poor sleep quality compared to non-GMAs. Adjusting for depressive symptoms did not diminish the significant association between poor sleep quality and GMAs, suggesting a potential link between depression and sleep disparities among GMAs.

Summary: City planning has the potential to improve public health by promoting healthier lifestyles. However, there is limited evidence from cities in developing countries. A study conducted in Cali, Colombia found that women and the poor reported poorer physical and mental health, and overweight-obesity is slightly increasing in the city, particularly among women.

Summary: This study examined the impact of the Futuros Fuertes intervention on infant feeding, screen time, and sleep practices in low-income Latino families. The results showed that the intervention group had higher fruit intake, breastfeeding rates, and lower screen time compared to the control group. Parental trust in intervention messaging and varying effectiveness of the intervention on different health behaviors were also identified.

Summary: The COVID-19 pandemic has had a significant impact on daily life, resulting in increased stress, anxiety, and depression, as well as changes in sleep and eating behaviors. Quarantine and isolation have particularly affected mental health in children and the elderly. Sleep disorders and negative dreams contribute to poor sleep quality and health issues. Sedentary lifestyles and emotional effects have led to unhealthy eating patterns and obesity. Addressing these challenges requires prioritizing mental health, promoting healthy sleep habits, and addressing obesity factors.

Summary: This study aimed to examine the effects of an educational lifestyle intervention on body weight and psychological health among Chinese community-dwelling overweight/obese patients with severe mental disorders (SMD). The results showed that after 12 months, the intervention group had significant reductions in body weight, body mass index, and waist circumference compared to the control group. Additionally, the intervention group reported higher life satisfaction and a decrease in depressive symptoms.

Summary: This study aimed to examine the impact of environmental toxicants, such as phthalates, parabens, and phenols, on adolescent sleep health. The results suggest that higher exposure to these toxicants may be associated with longer sleep duration and later sleep timing during adolescence, with potential variations by sex.

Summary: This study investigated the relationship between parental mental health symptoms and feeding styles in parents of formula-fed infants. The results showed that greater depressive symptoms were associated with the pressuring and laissez-faire feeding styles, while greater symptoms of stress and anxiety were associated with lower scores in these styles. The study recommends increased screening for depressive symptoms and providing responsive feeding support to parents.

Summary: The aim of this study was to determine the influence of specific psychological factors on intervention effects for children with severe obesity in a clinical setting. The results showed that parents' report of their child's emotional well-being and maternal education significantly predicted weight loss in the total sample, and social functioning was found to be a significant moderator of treatment effect. These preliminary findings suggest the need for tailored obesity programs that take into consideration a child's emotional and social functioning.

Summary: Arginine vasopressin (AVP) expressing neurons in the hypothalamic suprachiasmatic nucleus (SCN) provide output signals for synchronizing daily rhythms and are closely associated with the third ventricle, communicating with the cerebrospinal fluid (CSF). Contrary to previous assumptions, AVP neurons do not fully delineate the borders of the SCN, and exhibit heterogeneity in their distribution. Additionally, AVP distribution varies along the rostral-caudal axis of the SCN, with smaller neurons found in the rostral region.

Summary: Researchers have identified small local groupings of neurons, termed phaseoids, in the SCN through exploring the network topology using different techniques. The local differences in phase among these phaseoids are distinct from the global phase relationship. Results show that a gradient in connectivity strength in the SCN can explain the observed gradient of phaseoid strength, providing a parsimonious explanation for the heterogeneous oscillatory structure of the SCN.

Summary: The study describes a second portal system in mice that enables important secreted signals to reach specialized targets in high concentrations without dilution. These brain clock portal vessels provide a new route and targets for SCN signals, potentially reshaping our understanding of brain communication pathways.

Summary: A map of central nervous system organization based on vascular networks reveals new organizational layers. Portal pathways enable neurochemical signals to bypass systemic circulation and reach local targets. Anatomical studies have identified portal pathways linking different regions, opening new avenues for research on directional flow, signal identity, and functional significance of these pathways.
