This week, we present advances in the treatment of idiopathic pulmonary fibrosis, hypothalamic obesity, and lung cancer. We review nutrition in critical illness and follow a diagnostic case involving a patient who had a lung transplant. The Editors warn about the politicization of science. We discuss the dead donor rule in an era of voluntary euthanasia. Perspectives explore the forthcoming crisis in long-term care, reproductive medicine, and the realities of caring for loved ones at the end of life.
