Season 1

What makes people more or less susceptible to the deleterious effects of sleep loss? This episode is principally focused on this question and we are grateful to digitally sit down with Dr. Olga Galli as we discuss their recent publication in SLEEP entitled “Predictors of interindividual differences in vulnerability to neurobehavioral consequences of chronic partial sleep restriction.” LISTEN NOW

In this month’s episode of the SRS Podcast, we sit down with Dr. Todd Arnedt, who is currently a professor of psychiatry and neurology at the University of Michigan, where he serves as the co-director of the Sleep and Circadian Research Laboratory and Director of the Behavioral Sleep Medicine Program. Dr. Arnedt discusses his paper, Telemedicine versus face-to-face delivery of cognitive behavioral therapy for insomnia: a randomized controlled noninferiority trial, published in SLEEP. LISTEN NOW

In this month’s episode of the SRS Podcast, we sit down with Dr. Renske Lok, who is currently a postdoctoral researcher at Stanford University, where she is investigating the role of 24-hour rhythmicity and light on various processes in the human body, such as temperature, sleep and alertness. Dr. Lok discusses her paper, Physiological correlates of the Epworth Sleepiness Scale reveal different dimensions of daytime sleepiness, published in SLEEP Advances. LISTEN NOW

In this month’s episode of the SRS Podcast, we sit down with Dr. Josiane Broussard, who is currently a a clinical and translational scientist interested in the intersection of sleep & circadian rhythms and cardiometabolic health at the whole body as well as tissue-specific level. She received her PhD in Molecular Metabolism and Nutrition from the University of Chicago, and then completed postdoctoral training with Dr. Richard Bergman in Los Angeles, CA studying the effects of diet-induced obesity on insulin sensitivity in a large animal model. Dr. Broussard discusses her paper, Impairments in glycemic control during Eastbound transatlantic travel in healthy adults, published in SLEEP Advances. LISTEN NOW

Just in time for the return to school, we sit down with Dr Lisa Meltzer to discuss two vital papers at the intersect of sleep, school start times, and education modality among pediatrics, adolescents, and teenagers. Lisa Meltzer is a Professor of Pediatrics at National Jewish Health and a Professor of Family Medicine at the University of Colorado School of Medicine. She is a licensed clinical psychologist who is certified in Behavioral Sleep Medicine by the American Board of Sleep Medicine, and is a Diplomate of the Board of Behavioral Sleep Medicine. Dr. Meltzer’s funded program of research has examined sleep across development, the impact of pediatric chronic illnesses on sleep in children/adolescents and their parents, objective and subjective measures of pediatric sleep, the impact of changing school start times on health outcomes, and socio-ecological factors that contribute to sleep health disparities in toddlers and school-aged children. LISTEN NOW

Today’s episode deviates from the traditional episode approach. Instead of focusing on a specific, scientific investigation or multiple investigations pertaining to a singular topic, our guest, Dr. Diego Mazzotti, is going to review a white paper from a recently performed workshop between experts in translational informatics and sleep research. This workshop was purposed to discuss opportunities and challenges in defining strategies for data harmonization, with an ultimate goal of fueling discussion and fostering innovative approaches for data integration and development of informatics infrastructure supporting multi-site collaboration among sleep researchers. Dr. Diego Mazzotti is an Assistant Professor in the Division of Medical Informatics, Department of Internal Medicine at the University of Kansas Medical Center. Dr. Mazzotti received his Ph.D. in Psychobiology at the Federal University of São Paulo, Brazil and a Certificate in Biomedical Informatics from the University of Pennsylvania Perelman School of Medicine. LISTEN NOW

Today’s episode focuses on the investigation Performance of a Multisensor Smart Ring to Evaluate Sleep: In-Lab and Home-Based Evaluation of Generalized and Personalized Algorithms, which was published in June 2022 in the the journal SLEEP . Our guest today, Dr. Michael Grandner, will guide us through the study which evaluated a novel, commercially available sleep tracking device known as the “Happy Ring.” Importantly, this investigation not only evaluated the general capabilities of the Happy Ring, but also assessed whether integrating personalization into the device’s algorithm could improve device performance. It is this key piece of innovation that distinguishes the Happy Ring, as the overwhelming majority of measurement tools still employ a generalized, one-size-fits-all approach that is likely to degrade performance abilities. LISTEN NOW

Today’s episode focuses on a recently published manuscript in the journal SLEEP, entitled Melatonin suppression does not automatically alter sleepiness, vigilance, sensory processing or sleep, that reviews an investigation purposed to address this gap in knowledge. In this episode, our host is joined by the lead author from the manuscript, Dr. Christine Blume, to discuss this investigation, which leveraged a novel technique known as metameric light or silent substitution to isolate the effects of evening light exposure on ipRGCs while controlling the effects on other photoreceptors. LISTEN NOW

Episode 082. Novel Light Intervention to Fight Social Jet Lag in Teens.
Interviewee: Jamie Zeitzer, PhD
Description: In this episode of humanOS Radio, Dan Pardi welcomes Dr. Jamie Zeitzer back to the show. Jamie is an Assistant Professor in the Department of Psychiatry and Behavioral Sciences at Stanford University, as well as at the VA Aging Clinical Research Center at Stanford. In their previous interview, they discussed his research on light and timing of biological rhythms. He and his colleagues determined that brief, intermittent flashes of light have a much bigger impact on clock timing than continuous light exposure. This has interesting implications for shift workers, as well as for people who travel across multiple time zones and are subject to jet lag. In theory, you could expose yourself to brief flashes of light while you are asleep and effectively trick your brain into adjusting to a new time zone. But could it also be useful for social jet lag – meaning a chronic misalignment between the biological clock and the time when one is forced to be awake and active? In particular, could it be effective for teenagers who have to get up to go to school at a time when their body is driving them to sleep?
