Response: Earlier research had found people are less likely to say they'll receive a COVID-19 vaccine offered to them under an Emergency Use Authorization (EUA) than one offered to them following full FDA approval. Earlier surveys had also found that only around 30% of health care workers intended to receive a COVID-19 vaccine. Because the public often looks to local health care workers for health advice, and in most prioritization schemes they were slated to be offered vaccines first, this was quite concerning for the prospect of achieving population immunity. Commenters had warned that if the FDA chose to make COVID-19 vaccines available under EUAs, that substantial efforts would need to be made to ensure trust. On Dec. 4, 2020, an announcement about anticipated vaccine availability was emailed to all 23,784 Geisinger employees, who were asked to indicate their intention to receive a vaccine when one was available to them and the reasons for any hesitation they might have.

Response: Industry spends more on detailing visits and free samples than any other form of prescription drug marketing. There is good evidence that these activities can lead to more use of expensive new drugs over equally effective cheaper options. Given these concerns there have been efforts by some hospitalls and practices to restrict these forms of marketing.
We asked physicians in group practices delivering primary care about how often pharmaceutical reps visit their practice and whether they have a free sample closet.

MedicalResearch.com: What is the background for this study?
Response: Although marijuana is still classified as a Schedule I drug at the Federal level, as of June 2019, 33 states and the District of Columbia have legalized one or more forms of marijuana; 11 states and the District of Columbia have approved both medical and recreational uses. Public opinion on marijuana has changed dramatically over the last two decades and support for legalization has doubled since 2010. However, very little is known about the prevalence and patterns of marijuana use among adults with medical conditions.
This study analyzed the 2016 and 2017 Behavioral Risk Factor Surveillance System data to report the prevalence and patterns of marijuana use among adults with self-reported medical conditions.

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.
