Summary: The cortisol awakening response (CAR) is a crucial point in the healthy cortisol circadian rhythm, preparing the brain for challenges and promoting neurocognitive efficiency. Studies have found a causal link between CAR and its proactive role in optimizing functional brain networks.

Summary: The cortisol awakening response (CAR) shows a robust circadian rhythm that is influenced by the circadian system. This rhythm persists even after adjusting for prior sleep, suggesting the importance of circadian factors in the physiological response to waking. This has implications for shift workers who wake up at unusual circadian phases and may experience diminished responses to stressors.

Summary: This study assessed the reliability and validity of using 3-sample AUCi versus 5-sample AUCi in healthy and case individuals. The results showed that collecting three samples at 0-30-60 min provided similar AUCi estimates compared to five samples, but with smaller effect sizes and standard errors.

Summary: The study found that prior day sleep duration and physical activity levels can interact to predict the cortisol awakening response (CAR) the following morning, with short sleep duration and high levels of physical activity resulting in an augmented CAR. The effects of sleep and physical activity on CAR demonstrate an interactive effect.

Summary: This study aimed to analyze the hormonal stress burden of emergency physicians in the airborne rescue service, finding a significantly higher stress load on working days. Professional years and gender were also found to be statistically significant for the cortisol level of emergency physicians.

Summary: This study used mathematical equation modelling to explore the relationship between diurnal cortisol levels and telomere length within the context of sex. Results showed significant sex differences, with males demonstrating a positive correlation and females a negative correlation between cortisol awakening responses and telomere length. This suggests that when investigating telomere length, factors such as sex and sex hormones need to be carefully considered.

Summary: This study found no significant changes in the cortisol awakening response (CAR) over the menstrual cycle, and no significant association with variations in estradiol and progesterone. These results suggest that CAR is largely robust against hormonal variations across the menstrual cycle.

Summary: The study examined how trait resilience, social support, socially prescribed perfectionism, trait worry and trait impulsivity influenced the cortisol awakening response (CAR) in individuals vulnerable to suicide. Findings showed that the suicide vulnerability group had higher levels of worry, socially prescribed perfectionism and impulsivity, as well as lower levels of resilience and social support compared to the control group. Lower resilience and higher perfectionism, worry and impulsivity were associated with smaller total CAR.

Summary: This study aimed to evaluate the cortisol response in pediatric oncologic patients during febrile episodes. The results showed that 69% of the patients had a cortisol level below 14.6 μg/dL during fever, and significantly lower cortisol levels were observed in patients who received dexamethasone, posaconazole, or had less than 7 days since the last glucocorticoid intake.

Summary: The study found a curvilinear inverted-U relationship between low childhood income and cortisol awakening response (CAR), with children from low-income families having both the lowest and highest CAR. However, childhood income was not associated with adolescent cortisol diurnal slope or AUC.

Summary: This study explores the extent to which changes in family composition and family-related life events are associated with the levels of family-based social capital in later years using data from a large survey of older adults in Switzerland. The study finds that family networks are highly dynamic, with significant effects on social capital observed when adding or omitting important family members, while family-related life events have marginal effects.

Summary: Individuals with schizophrenia have higher rates of metabolic syndrome (MetS) and show decreased long-term cortisol output, which may be associated with dysregulation in the hypothalamic pituitary adrenal (HPA) axis. MetS is correlated with increased hair cortisol concentrations (HCC), indicating elevated cortisol levels in schizophrenia patients.

Comparable data distributions between online and laboratory assessments suggest the feasibility of eCOGTEL across the adult lifespan.

Summary: This study aimed to examine the relationship between event-based prospective memory (EBPM) and life satisfaction, and whether this relationship is affected by executive functions and retrospective memory. The findings showed that EBPM was related to health-related quality of life (HrQoL), but this relationship was eliminated after controlling for executive functions. Life satisfaction was not related to any cognitive variables.

Summary: In laboratory time-based prospective memory tasks, older adults perform worse than younger adults. Less frequent clock checking due to executive function problems may be responsible. This study aimed to investigate the role of clock checking in older adults' time-based prospective memory and whether executive functions would be associated with clock checking and time-based prospective memory. The results showed that time-based prospective memory declined with age due to less frequent clock checking. The link between executive functions and clock checking or time-based prospective memory was only found when not controlling for age.

Summary: This study examined the associations between life-course socioeconomic conditions and cognitive performance in older adults. The findings suggest that socioeconomic disadvantage predicts lower cognitive performance across different domains, and individuals who experienced socioeconomic disadvantage performed worse than those who experienced upward social mobility. However, the associations between socioeconomic disadvantage and cognitive decline were less consistent.

Summary: A recently developed virtual reality task, EPELI, assesses goal-directed behavior in naturalistic conditions. It was tested on 77 typically developing 9-13-year-old children to examine its properties. The study confirmed the reliability and ecological validity of EPELI for assessing attention, executive functions, and prospective memory in children.

Summary: Individual differences in emotional coping styles can impact information processing at different stages. Repressors show a strong approach tendency towards positive stimuli, while sensitizers display a strong avoidance tendency. There were no significant group differences in attention bias and approach/avoidance bias. These findings highlight the association between emotional coping styles and information processing.

Summary: Musical training can enhance fine motor skills, cognitive abilities, and induce changes in the structure of the brain. In this study, older adults were randomly assigned to either piano training or music listening. The results showed that practicing piano led to greater improvement in fine motor skills and working memory, and the consolidation of piano skills appeared to take place in sensorimotor networks.

Summary: In older adults' everyday life, time-based prospective memory (TBPM) is relevant, but it is still unclear which task-related factors can potentially moderate the age-related differences. The present meta-analysis aimed to quantify age-related differences in laboratory TBPM tasks and investigate how specific task-related factors potentially moderate the age effects. The results showed that older adults performed worse in TBPM and checked the clock less often than younger adults, especially for shorter intervals. Furthermore, the duration of the PM target time interacted with the frequency of the PM task, suggesting that learning effects may attenuate the age differences in TBPM performance.

Summary: This study examines the association between depressive symptoms and prospective memory (PM) in older adults, and explores the potential influence of age, education, and metamemory representations. The results indicate that metamemory representations can buffer the negative effect of depressive symptoms on PM performance in old-old individuals.

Summary: This study aimed to investigate the feasibility of self-administered task-switching training in middle-aged working population. The results showed that although only 56.7% of caregivers completed over 50% of the instructed training sessions, compliant caregivers demonstrated significant training gains and transfer effects in an untrained task-switching task. No transfer effects were found in other cognitive tasks, but trained participants reported fewer everyday memory failures.
