A wealth of data is available from electronic health records (EHR) that are collected as part routine clinical care in hospitals worldwide. These rich, longitudinal offer an attractive object study for the field circadian medicine, which aims to translate knowledge rhythms improve patient health. This narrative review discuss opportunities EHR studies highlight methodological challenges, and provide recommendations using these advance field. In existing literature, we find real-world settings have potential shed light on key questions including how 24-hour features associated with—or even predictive of—health outcomes, whether effect medication or other activities depend time day, physiology may influence reference ranges sampling protocols. However, optimal use medicine requires careful consideration limitations sources bias inherent sources. particular, day influences almost every interaction between a healthcare system, creating operational patterns little nothing do with biology. Addressing challenges could help expand evidence base medicine.

Abstract Objectives Chronobiology is the science that studies biological rhythms based on direct methods and empirical time series of individual subjects. In laboratory medicine, factor often underestimated, no currently exist to study in population databases point-like, real-world data (RWD). Methods Retrospective (24 months, 2022–2023) were extracted for four measurands (sodium, potassium, chloride leukocytes) from emergency laboratory. Two different strategies grouping applied: clouds (with or without outliers) population-averaged profiles. Cosinor regression analysis was performed grouped derive circadian parameters. The parameters obtained here compared results literature, using series. Results A total 409,719 points analyzed. All exhibited symmetrical distributions, except leukocytes. did not visually display rhythmicity, but cosinor revealed a significant rhythm. removal outliers had minimal impact results. contrast, profiles showed visible which confirmed by with better goodness-of-fit clouds. Conclusions Population-averaged have advantages over characterizing deriving Population chronobiology, RWD, presented as an alternative classical overcomes limitations methods. Utilizing RWD provides new insights into relationship between chronobiology clinical practice.

The study of the ubiquitous circadian rhythms in human physiology typically requires regular measurements across time. Repeated sampling different internal tissues that house clocks is both practically and ethically infeasible. Here, we present a novel unsupervised machine learning approach (COFE) can use single high-throughput (omics) samples from individuals to reconstruct cohorts. COFE assign time-labels samples, identify rhythmic data features used for temporal reconstruction. With COFE, discovered widespread de novo gene expression eleven adenocarcinomas using TCGA database. arrangement peak times core clock was conserved cancers resembled healthy functional except mistiming few key genes. commonly genes were involved metabolism cell cycle.

Standardization plays a crucial role in ensuring the reliability, reproducibility, and interoperability of research data biomedical sciences. Metadata standards are one foundation for FAIR (Findable, Accessible, Interoperable, Reusable) principles management. They facilitate discovery, understanding, reuse. However, adoption metadata biological lags practice. Barriers such as complexity, lack incentives, technical challenges, resource constraints, resistance to change hinder widespread adoption. In field chronobiology, standardization is essential but faces particular challenges due longitudinal nature experimental data, diverse model organisms, varied measurement techniques. To address these we propose an approach that emphasizes simplicity practicality: development README templates tailored types species.
