Daylight Saving Time Starts Sunday. Here ’s What Losing An Hour of Sleep Really Does to Your Body
The start of Daylight Saving Time, when the clocks spring forward by an hour, is among the most hated days of the year. Aside from the obvious reason — losing an hour of sleep — research has shown that the time change, which this year falls on March 11, may contribute to everything from lost productivity to a heightened risk of heart attack and stroke. How can resetting your clocks do all that? TIME asked Dr. Cathy Goldstein, an assistant professor of neurology at the University of Michigan School of Medicine Sleep Disorders Center, what really happens to your body when you lose an hour of sleep for Daylight Saving Time. Your circadian rhythm is thrown off Daylight Saving Time’s true impact goes beyond losing an hour of sleep, Goldstein says. Your circadian rhythm, an internal clock that “exists so that wakefulness is promoted during the day, and sleep is promoted at night,” Goldstein says, is also affected. Thanks to circadian rhythms, the body begins secreting melatonin, a sleep-promoting hormone, around 9 p.m., with levels dropping way off by the next morning. Light exposure can moderate your circadian rhythm a bit, but the body more or less relies on consistent sleep and wakefulness cues — so when they’re altered, even by an hour, your sleep gets misaligned. “You take somebody who’s very sleepy when they get up at 6 a.m., and then they get up at 6 a.m. during Daylight Saving Time, and for them that’s physiologic...
I ’ve had a fever, a cough and breathlessness since February, and been in and out of hospital. If it isn’t coronavirus, what is it? BySimon HattenstoneI ’m lying in bed, shivering like crazy. My partner, Diane, is asleep, and I burrow deep into her back. I’m sweating like crazy, too. I’m desperate for the loo, and I run there in my shivery sweats and sweaty shivers. It’s only five minutes since I last went. When I sleep, the same obsessive m oment plays again and again. It’s to do with numbers. I need to get past number nine, but I can’t. The dream lasts for hours. Finally, I...
CONCLUSION: Structural prevention measures in addition to behavioral measures enable a reduction of the cancer risk caused by UV radiation. The aim must be to establish these measures nationwide for the entire population. PMID: 32494842 [PubMed - as supplied by publisher]
This study sought to determine the incidence rates of all gynecologic, including peritoneal, malignancies in the U.S. Active Duty population compared to the general US population as reported in the Surveillance, Epidemiology, and End Results Program database. MATERIALS AND METHODS: Gynecologic cancers diagnosed in U.S. Active Duty women aged 20-59 between 2004 and 2013 were retrospectively ascertained. Cancer cases were identified in both the Automated Central Tumor Registry and the Military Health System Data Repository. All cases in Automated Central Tumor Registry plus cases recorded in Military Health System Data R...
CONCLUSIONS: Although statistical significance was not reached, the efficacy of prasugrel was potentially different between stroke subtypes, warranting further studies. PMID: 32493881 [PubMed - as supplied by publisher]

CONCLUSIONS: Our data provide new insights into the biology driving metastasis in PTCs and highlight how lncRNAs cooperate with coding transcripts to sustain these processes. PMID: 32495722 [PubMed - as supplied by publisher]
CONCLUSIONS: Fusion genes were the most common genetic cause of pediatric PTCs. Fusion gene positive PTCs showed more aggressive behavior than fusion gene negative PTCs. Several novel rearrangements were identified. Fusion genes seem to be a molecular marker number one in pediatric PTC patients. PMID: 32495721 [PubMed - as supplied by publisher]
