Tumour purity assessment with deep learning in colorectal cancer and impact on molecular analysis.

Tumour content plays a pivotal role in directing the bioinformatic analysis of molecular profiles such as copy number variation (CNV). In clinical application, tumour purity estimation (TPE) is achieved either through visual pathological review [conventional pathology (CP)] or the deconvolution of molecular data. While CP provides a direct measurement, it demonstrates modest reproducibility and lacks standardisation.

Integrated bioinformatics and interaction analysis to advance chronotherapies for mental disorders.

Introduction: Robust connections have been identified between the pathophysiology of mental disorders and the functioning of the circadian system. The overarching objective of this study was to investigate the potential for circadian rhythms to be leveraged for therapeutics in mental disorders.

Methods: We considered two approaches to chronotherapy-optimal timing of existing medications ("clocking the drugs") and redressing circadian abnormalities with small molecules ("drugging the clock").

"I didn't go into medicine just to be on the phone": Emotional Expression as Sacrosanct During Derious Illness Patient-Physician Advanced Cancer Care Communication During the COVID-19 Pandemic.

Guided by communication accommodation theory, we studied 27 physician reports of patient-physician advanced cancer communication during the COVID-19 pandemic. Advanced cancer communication requires recognizing patients' psychosocial states and collaboratively engaging patients empathetically to develop the shared understanding necessary to guide decision-making. However, physicians found their communication underaccommodated, stemming from personal protection equipment, social distancing, and telemedicine.

Reconfiguration of metabolic connectivity in ageing.

Information transfer across the brain has a high energetic cost and requires efficient glucose metabolism. Here we use recently developed high temporal resolution functional positron emission tomography (fPET) to create a timecourse of glucose metabolism for individual subjects and assess the relationship between metabolic connectivity and cognitive function in ageing. The metabolic connectomes of 40 younger (mean 27.
