It can be comforting to be watched. At the swimming pool, it is reassuring for children and adults alike when there is a lifeguard on duty, eagle-eyed and ready to rescue those in distress. At home, modern parents can invest in remote video technologies to observe their kids even when Mom or Dad is out of the house or simply in another room.

BigPharmaLiving With Cancer: A Broken Covenant With Patients by Susan Gubar, NY Times Well Section published January 15, 2016


A comment from Dr. Mark Lewis, CKN Social Media Editor

Participation in a clinical trial is, ideally, a two-way street. The patient potentially stands to gain therapeutic benefit while the researchers learn about the efficacy and toxicity of the intervention under study. This post on the New York Times Well blog highlights concern about a lack of transparency in reporting the outcomes of trials, even if they generated negative results or, to quote Susan Gubar, “adverse consequences.”
