For those who’ve been reading for awhile, you’ve probably surmised that one of my personal health interests is seasonal and pandemic flu. There were plenty of stories about that this week, so that’s what we’ll focus on. We’ll also look at Ebola and other stories you may have missed. My apologies for posting delays this week, I’m dealing with some rotator cuff and carpal tunnel issues in my right arm, and let me tell you, it is HARD to type with your dominant arm in a sling!
Enjoy your holiday Monday (if you have one) and have a safe and healthy week!
The CDC has said that this year’s seasonal flu vaccine was only 23% effective due to unanticipated antigenic drift—meaning the predicted strains in the vaccine didn’t match the dominant strains of the virus that are currently circulating. In order to combat this in the future, scientists at Mount Sinai health system in New York are in the process of testing a universal flu vaccine which will go into clinical trials this year.
KLTV.com—“‘There is work going on to see if, perhaps a different kind of vaccine could be developed maybe against a different part of the flu virus, one that is not so subject to this antigenic drift or to change as readily from one year to the next,” [Dr. Levin of UT Health Northeast] says.”
Scientists at Washington State University in Spokane have found a brain protein that boosts the healing power of sleep and speeds recovery from the flu in mice. Professor James M. Kruger said this discovery could lead to alternative treatments for flu and other infectious diseases by stimulating production of the brain protein called AcPb. This discovery comes at a time where avian influenza is prevalent in Taiwan, Japan, Nigeria, China, Egypt, Canada, the U.S. and Mexico.
Washington State University—“Krueger showed this recovery involves AcPb and an immune system signaling chemical called interleukin-1. AcPb links up with interleukin-1 to help regulate sleep in healthy animals. It also prompts infected animals to spend more time sleeping during an illness.
In the study, mice who lacked the gene for AcPb slept less after being infected with influenza virus. They also became chilled, grew sluggish, lost their normal circadian rhythms and ultimately died in higher numbers than the mice who slept longer.”
This Week in Ebola
As GMU students return to classes, so do students in Ebola affected Guinea. Schools in Guinea will re-open Monday, and schools in Liberia are set to re-open “next month.” No date has been set for schools in Sierra Leone. Despite this, the President of Sierra Leone has declared that there will be zero new confirmed Ebola cases by the end of March the country will be Ebola-free, by WHO standards, by May. These announcements come at a time when Dr. Thomas Frieden, Director of the CDC, has said he was “very confident we can get to zero cases in this epidemic if we continue the way we’re going and nothing unexpected happens” and the outbreak appears to be slowing down. Last week brought record low numbers—for Guinea, the lowest total since mid-August; for Liberia, the lowest total since the first week of June; for Sierra Leone the second week of declines and the lowest level since the end of August. However, there are still “at least 50 micro-outbreaks” underway throughout West Africa.
Pauline Cafferkey, the Scottish nurse infected with Ebola, is “showing signs of improvement” and an American soldier who was found dead in Texas after his deployment in West Africa reportedly showed no signs of Ebola leaving officials to remark that there was “no evidence of a public health threat.”
A seemingly large amount of good news this week left space for new ruminations on Ebola and outbreaks in general. Wired had an interesting piece on Nanobiophysics and how it could stop future global pandemics while The Chicago Tribune looked at bats and their likely role in Ebola outbreaks and CNBC looked at the price of protection from global pandemics—would you believe $343.7 billion?
Stories You May Have Missed
- Last week we learned about dirt as a potential source for new antibiotics. This week, there were stories about new antibiotics coming from arctic waters.
- How useful would a device that sniffs out chemical weapons be? Potentially very useful for those workers tasked with cleaning up mustard gas and lewisite, says an article in New Scientist.
- Computer modeling by researchers at MIT, Draper Laboratory, and Ascel Bio could forecast reaction to disease outbreak. This model looks at reactions through news reporting and social media in collaboration with hospital records of actual disease incidence.
