Aims: To propose an original evaluation and validation of the Clock Face Test (CFT).
Method: Outpatients; 163 elderly people, aged over 65 years. Factory analysis, Student's test.
Results: The test shows a positive correlation with Folstein's MMSE (r = 0.769) and Signoret's BEC 96 (r = 0.644), a good specificity (75% with MMSE; 79% with BEC 96) and a good sensitivity (87% with MMSE; 74% with BEC 96). Four factors are identified by factory analysis; 74% of the variancy is explained by the first three factors.
Conclusion: The CFT is a valid tool, easy to conduct. Several applications are possible for diagnosis, psychometric control and therapeutic trials.

Background: An aging population in combination with more gentle and less stressful surgical procedures leads to an increased number of operations on older patients. This collectively raises novel challenges due to higher age heavily impacting treatment. A major problem, emerging in up to 50% of cases, is perioperative delirium.

Metabolomics and epigenomics have been used to develop 'ageing clocks' that assess biological age and identify 'accelerated ageing'. While metabolites are subject to short-term variation, DNA methylation (DNAm) may capture longer-term metabolic changes. We aimed to develop a hybrid DNAm-metabolic clock using DNAm as metabolite surrogates ('DNAm-metabolites') for age prediction.

A maternal high-fat diet (HFD) deteriorates the long-term metabolic health of offspring. Circadian rhythms are crucial for regulating metabolism. However, the impact of maternal HFD on the circadian clock in white adipose tissue (WAT) remains unexplored.

Changes in social zeitgebers across the lifespan affect the interaction between biological and social clocks, potentially contributing to social jetlag. Extant literature suggests a reduction in social jetlag given declining social obligations occurring after retirement, but is limited to self-reported methods and cross-sectional designs. Leveraging longitudinal and ecologically valid data from consumer sleep technology, we analysed objective sleep data from 2439 users of the polysomnography-validated SleepScore mobile application, encompassing 500,415 total nights recorded.

A key property of the circadian clock is that it is reset by light to remain synchronized with the day-night cycle. An attractive model to explore light input to the circadian clock in vertebrates is the zebrafish. Circadian clocks in zebrafish peripheral tissues and even zebrafish-derived cell lines are entrainable by direct light exposure thus providing unique insight into the function and evolution of light regulatory pathways.
