You didn’t think a Papal visit would slow us down, did you? Even in the event of a zombie apocalypse, we GMU Biodefense folks would still find a way to get out the weekly report – perhaps pigeon carrier? Until that happens, don’t forget to check us out on Twitter! This week saw a lot of great focus on collaborations to fight public health threats like antimicrobial resistance and epidemics. Schools in Chicago were closed for concerns over Legionnaires’ disease, yours truly provided a piece on Ebola infection prevention, and we have a wonderful opportunity to contribute to World Medical & Health Policy regarding women’s health on a global stage.

Learned Lessons from Ebola in the US
Sylvia Burwell, Secretary of Health & Human Services, discusses the clinical complexity and reality that “our clinical approach to treating Ebola in a hospital setting posed different challenges.” Several key US health experts weighed in on the pivotal first patient, Thomas Duncan, to unknowingly bring Ebola to the US. The implications for healthcare and preparedness sent a tidal wave of response across US hospitals. Dr. Tom Frieden, director of the Centers for Diseases Control and Prevention (CDC), also highlights three main lessons from not only the cases in Dallas, but also the Ebola epidemic as a whole. He points to the necessity of a strong surveillance and response system, need for rapid international aid, and better infection control in hospitals….which segues beautifully into our next story.

The Infection Prevention Angle of the 2014 Ebola Crisis
Reports and analyses from a range of responders to the crisis have been trickling out for several months now, but there’s a constant in all of them – infection control. Given my background and experiences in this field, I wanted to take our readers down the rabbit hole of what exactly it was like to be an Infection Preventionist during this time. A hopeful start to a series of pieces on this subject, it will give you a taste of not only the daily struggles, but the brevity of what potential Ebola patients meant for US healthcare preparedness.

Partnerships to Support Antibiotic Development
564px-Penicillin_Past,_Present_and_Future-_the_Development_and_Production_of_Penicillin,_England,_1943_D16963The ASPR’s (Office of the Assistant Secretary for Preparedness and Response) Biomedical Advanced Research and Development Authority (BARDA) is part of a larger initiative to use Other Transaction Authority (OTA – flexible advanced research and development funding instruments) to start developing business relationships between government and private industry. The relationships are mutually beneficial, allowing both parties to invest and develop products for biodefense and the growing threat of antibiotic resistance. Given the slowing of new antibiotic development, this joint agreement comes at a pivotal time for antimicrobial resistance efforts.

Three Chicago-area Schools Close in Response to Legionnaires’ Disease Concerns
Three schools in the Illinois U-46 district were shut down on Wednesday and Thursday after cooling tower test results showed “higher than normal levels of Legionella bacteria”. The OSHA recommended threshold is no higher than 1,000 CFU/ml (colony-forming units per milliliter) and with the outbreak among residents of the Illinois Veteran’s Home, it’s not surprising to see many water towers being frequently tested, etc. The important thing to note is that Legionella pneumophila infections are a result of the intensity of the exposure and the immune status of the exposed person. Legionella can’t be totally eradicated from the water supply and a majority cooling towers will contain some amount of growth.

Call for Papers – Women’s Health in Global Perspective
Papers sought for a special issue and workshop of World Medical & Health Policy on “Women’s Health in Global Perspective,” to contribute to understanding and improve policy related to women’s health and wellbeing.  Forces ranging from the economic to the climactic have human repercussions whose genesis and solutions demand consideration of their global context.  A wealth of recent research and inquiry has considered the particular plight of women, who often suffer disproportionately from lack of education, compromised nutrition, poverty, violence and lack of job opportunities and personal freedom.  The Workshop on Women’s Health in Global Perspective will consider the broad ranging social determinants of health on a global scale that importantly influence health outcomes for women everywhere, which in turn has implications for economic, political and social development.

Stories You May Have Missed:

  • Personal Microbial Cloud – researchers found that a person’s microbiome form a cloud around them, allowing scientists to identify a specific person just by sampling their microbial cloud. Food for thought: would this be our microbial cloud version of a fingerprint?
  • C. Difficile Drug Success – Researchers at Stanford University School of Medicine were successful in their ability to get rid of the deadly gastrointestinal toxin via a drug that didn’t focus on the organism, Clostridium difficile, but rather the toxin itself. C. difficile is responsible for 250,000 hospitalizations and 15,000 deaths per year while costing the US more than $4 billion in healthcare expenses. Yay for successful treatments!
  • EC, EU, and WHO Work To Better Share Private Drug Data – The European Commission, European Medicines Agency, and World Health Organization are working to “step up coordination” on EU medicines regarding safety, quality, and efficacy of new drug candidates. The first step in solving a problem is recognizing you have one, right? The new focus on global public health threats is one we can all appreciate!
  • WHO Makes Changes to Southern Hemisphere Flu Vaccine – The WHO committee recommended changes for two of the three trivalent influenza vaccines for the Southern Hemisphere next year due to changes in the circulating viral strains. They suggested using H1N1, H3N2 an A/Hong Hong/4801/2014-like virus, and for influenza B, the Brisbane/60/2008-like virus. In the quadrivalent vaccine, they recommended adding the influenza B Yamagata lineage component, with the A/H1N1 strain staying.

Editor’s note: As Managing Editor, I know my job is never done because the news never stops. As a social scientist, I know there is always more than one side to any story. As such, before we get into the news roundup for March 14, here are two follow up articles from our report last week.

Mount Sinai Scientists Discover How Marburg Virus Grows in Cells

Last week we learned about BCX4430, a drug that could possibly treat Marburg virus. This week, news coming out of Mount Sinai in New York outlines further research findings on the virus that can lead to greater understanding or possible development of virus inhibitors. The full findings of this research are available at Cell Reports.

Newswise — “A protein that normally protects cells from environmental stresses has been shown to interact Marburg virus VP24, allowing the deadly Marburg virus to live longer and replicate better, according to a cell culture study led by scientists at the Icahn School of Medicine at Mount Sinai. The investigators say that deciphering the molecular details of how Marburg virus and the host protein interact may help in developing inhibitors of the virus.”

Nazi Scientists May Have Plotted Malaria Mosquito Warfare (Redux)

As was pointed out by our eagle-eyed reader Jean Pascal Zanders, there, of course, is disagreement about the supposed Nazi insect weapons program. Jean writes about it on his blog, and GMU Biodefense’s own, Dr. Gregory Koblentz, is incredulous.

National Geographic – “‘Research to assess the threat posed by different biological agents and vectors, such as May’s research on mosquitoes and malaria, is especially hard to categorize as offensive or defensive,’ Koblentz says. ‘Even if May’s intent was offensive, it was very preliminary-many steps away from actually producing a viable insect-borne biological weapon.’”

And now for our regularly scheduled Friday news…

Highlights include Project BioShield, Destruction of Syrian chemical weapons, and  Clostridium difficile with antibiotics. Happy Friday!

The Only Thing Scarier Than Bio-Warfare is the Antidote

Should we be afraid of bio-terror or bio-error? In this massive, front-page Newsweek story, the author looks at the creation of the Project BioShield Act and its resulting effects including the Public Readiness and Emergency Preparedness Act and increased availability of biological threat agents used for scientific research. The Soviet bioweapons program, BSL-4 labs, and the intersection of science and government are also addressed.

Newsweek – “Though BioShield’s initial goals made sense when the threat of biological warfare seemed imminent, the act may have permanently undermined some of the essential protections against unsafe practices in at least one area of science research: the regulations that keep untested drugs off the market, and labs from leaking deadly biological agents into the environment.”

Greeks protest against Syria chemical weapon destruction at sea

Under the UN Security Council backed deal to deal to destroy Syria’s chemical weapon arsenal, provisions are included for this to happen aboard a U.S. cargo ship in the eastern Mediterranean Sea.  Under the plan, hydrolysis systems aboard the ship are to mix heated water and other chemicals to break down the lethal agents, resulting in a sludge equivalent to industrial toxic waste. This plan has prompted protests in Italy, Malta, and Greece despite assurances there will be no negative impact on the surrounding environments.

Agence France-Presse – “‘If this happens it will obliterate the island’s economy, will pollute the sea and will lead the people of the Mediterranean to a grim future.’ Pavlos Polakis, mayor of the city of Sfakia told AFP.”

Severe diarrheal illness in children linked to antibiotics prescribed in doctor’s offices

According to the CDC, an overwhelming percentage of cases of pediatric Clostridium difficileinfection occur in children who were prescribed antibiotics during the 12 weeks prior to illness for unrelated conditions—such as ear, sinus, or upper respiratory infections.  C. difficile is a bacteria that causes severe diarrhea and is potentially life threatening.

CDC – “Taking antibiotics is the most important risk factor for developing C. difficile infections for both adults and children.  When a person takes antibiotics, beneficial bacteria that protect against infection can be altered or even eliminated for several weeks to months. During this time, patients can get sick from C. difficile picked up from contaminated surfaces or spread from a health care provider’s hands.”
