MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Public support for aid in dying in the United States is rapidly growing. As a result, we’re now seeing debates about whether to expand access to aid-in-dying to new populations – such as people with Alzheimer’s disease – who wouldn’t be eligible under current laws.
With those debates in mind, we asked currently healthy people who recently learned about their risk for developing Alzheimer’s disease dementia (i.e., due to the presence of amyloid, an Alzheimer’s disease biomarker) whether they would be interested in aid-in-dying.
Our findings suggest that about 20% of individuals with elevated amyloid may be interested in aid-in-dying if they become cognitively impaired.

MedicalResearch.com: What is the background for this study?
Response: Cancer diagnosis requires manual analysis of tissue appearance, histology, and protein expression. However, there are certain types of cancers, known as cancers of unknown primary, that are difficult to diagnose based purely on their appearance and a small set of proteins. In our precision medicine oncogenomics program, we needed an accurate approach to confirm diagnosis of biopsied samples and determine candidate tumour types for where the primary site of the cancer was uncertain. We developed a machine learning approach, trained on the gene expression data of over 10,688 individual tumours and healthy tissues, that has been able to achieve this task with high accuracy.
Genome sequencing offers a high-resolution view of the biological landscape of cancers. RNA-Seq in particular quantifies how much each gene is expressed in a given sample. In this study, we used the entire transcriptome, spanning 17,688 genes in the human genome, to train a machine learning method for cancer diagnosis. The resultant method, SCOPE, takes in the entire transcriptome and outputs an interpretable confidence score from across a set of 40 different cancer types and 26 healthy tissues.
