Book Review: Living Light:  The Art of Using Light for Health & Happiness

While it’s hard not to notice the brilliant display of colors set off by a sunset over the water, we seldom consider the biological, or even psychological, benefits of light. “It is my belief that good quality light in our daily lives is far more important than we might think,” writes Karl Ryberg. In his new book, Living Light: The Art of Using Light For Health And Happiness, Ryberg brings us his life’s work — studying the obvious and not so obvious ways in which light affects us and how we can use light in our lives not only function better, but feel better. Light, we know, plays an important role in seasonal affective disorder (SAD). Ryberg writes, “Research has (also) shown that lack of light in the wintertime has as impact on the part of the brain that produces serotonin, that mood regulator essential for our well-being.” Moreover, exposure to electric light — as oppose to natural sunlight — confuses our circadian rhythms. Ryberg points to a study that exposed a group of people to a week of camping without artificial light followed by a week of camping with electric light: “The team of researchers found that levels of melatonin, the hormone that is triggered in the pineal gland in our brains to make us feel sleepy, were slower to drop in the mornings with those exposed to electric light, making them feel groggy for longer.” Interestingly, animal studies have also linked exposure to twenty-four hour light to...

Online ahead of print.ABSTRACTThe initiation, progression, and metastatic spread of cancer elicits diverse changes in systemic physiology. In this way, cancer represents a novel homeostatic challenge to the host system. Here, we discuss how the hypothalamus, a critical brain region involved in homeostasis senses, integrates and responds to cancer-induced changes in physiology. Through this lens, cancer-associated changes in behavior (e.g., sleep disruption) and physiology (e.g., glucocorticoid dysregulation) can be viewed as the result of ...

This study aims to assess the cost of the hospital stay for the administration of anti-CD19 CAR-T cells in France. Data were collected from the French Medical Information Systems Program (PMSI) and all hospital stays associated with an administrated drug encoded 9439938 (tisagenlecleucel, Kymriah®) or 9440456 (axicabtagene ciloleucel, Yescarta®) between January 2019 and December 2020 were included. 485 hospital stays associated with an injection of anti-CD19 CAR-T cells were identified, of which 44 (9%), 139 (28.7%), and 302 (62.3%) were for tisagenlecleucel in acute lymphoblastic leukaemia (ALL), tisagenlecleucel ...
