Scaled-back NBAF and NBAF as designed are options that could meet critical US lab needs as part of integrated national strategy to protect animal and public health

WASHINGTON It is "imperative" that the U.S. build a large-animal biocontainment laboratory to protect animal and public health, says a new report by the National Research Council. Two options that could meet long-term needs include the National Bio- and Agro-Defense Facility (NBAF) facility as currently designed, or a scaled-back version tied to a distributed laboratory network. Until such a facility opens that is authorized to work with highly contagious foot-and-mouth disease, the Plum Island Animal Disease Center located off Long Island should remain in operation to address ongoing needs. The report concludes that there are important drawbacks for the U.S., should it rely solely on international laboratories to meet large animal Biosafety Level 4 needs in the long term.

The proposed NBAF in Manhattan, Kan., would be the world's fourth Biosafety Level 4 laboratory capable of large animal research and would replace the aging Plum Island facility. NBAF would study highly contagious foreign animal diseases -- including foot-and-mouth disease, which affects cattle, pigs, deer, and other cloven-hoofed animals -- as well as emerging and new diseases that can be transmitted between animals and people. However, given the estimated cost of $1.14 billion to construct NBAF at the proposed site and the country's current fiscal challenges, the U.S. Department of Homeland Security requested that the National Research Council analyze whether three options could meet the nation's laboratory infrastructure needs.

The three options as stipulated by DHS were: constructing NBAF as designed, constructing a "scaled-back" version of NBAF, and maintaining current capabilities at Plum Island Animal Disease Center. Because the Plum Island facilities do not have large animal Biosafety Level 4 capacity -- containment of agents that are potentially life-threatening to humans and pose a high risk of transmission -- this type of work would have to be conducted at foreign laboratories.

The scope of the committee's analysis was limited to examining the three options and explicitly excluded an assessment of specific site locations for the proposed laboratory facility; therefore, the report neither compares relative risks of the three options nor determines where foot-and-mouth disease research can be safely conducted. In addition, the committee concluded that to most appropriately fill laboratory needs, all factors of concern will need to be considered in a more comprehensive assessment.

The report concludes that DHS' first option -- NBAF as currently designed -- includes all components of the ideal laboratory infrastructure in a single location and has been designed to meet the current and anticipated future mission needs of DHS and the U.S. Department of Agriculture's Agricultural Research Service and Animal and Plant Health Inspection Service. However, the proposed facility also has drawbacks, including substantial costs associated with construction, operation, and management; and not leveraging existing capacity at other containment laboratories in the U.S.

Regarding the second option, the report finds that a partnership between a central national laboratory of reduced scope and size and a distributed laboratory network can effectively protect the United States from foreign animal and zoonotic diseases, potentially realize cost savings, reduce redundancies while increasing efficiencies, and enhance the cohesiveness of a national system of biocontainment laboratories. However, the cost implications of reducing the scope and capacity of a central facility are not known.

In its assessment of the third option, the report says that maintaining the Plum Island Animal Disease Center and leveraging foreign laboratories for large animal Biosafety Level 4 needs would avoid the costs of constructing a new replacement facility. However, the facilities at Plum Island do not meet current standards for high biocontainment. Given the uncertainty over priorities of a foreign laboratory and logistical difficulties in an emergency, it would not be desirable for the United States to rely on international laboratories to meet these needs in the long term.

The report adds that because foot-and-mouth disease research remains critical for the U.S. animal health system, it will be essential to maintain the Plum Island facility until an alternative facility is authorized, constructed, commissioned, and approved for work with the virus.

Regardless of the options considered for a central facility, the report recommends that DHS and USDA develop and implement an integrated national strategy that utilizes a distributed system for addressing foreign animal and zoonotic disease threats. The capital costs associated with maintaining or constructing modern laboratory facilities should be balanced with the need to support research priorities. Therefore, it is critical for DHS and USDA to develop solutions that strike a balance between facilities costs and the research and development effort needed to protect American agriculture and public health.

Teijin Develops New Lightweight Polymer Resin for Automotive ...

By Nick Gilbert


Teijin Chemicals, the resin and plastic processing business arm of Teijin Group, has declared that Panlite AM-9937F has been specifically developed for use in automotive applications. This new material combines an ultra-smooth surface and exceptional dimensional precision.

The product designs are enabled by this material that were unattainable in the past because of the limitations in traditional metal. The company intends to commercialize this new material for use in external automotive body components and garnish, and anticipates attaining yearly sales of 10 billion yen, by financial year 2020.

Panlite AM-9937F is a lightweight polymer alloy, which is a combination of the company?s own polycarbonate Panlite and polyester resin. The main feature of the material includes flexibility in design, moldability, high resistance to corrosion, heat and impact, and a low linear expansion coefficient. Automobile manufacturers are provided with an option to minimize the weight of components by approximately 20%, with the help of this new material. Panlite AM-9937F has been used in the LEXUS HS250h hybrid sedan?s luggage door garnish.

Enhanced fuel efficiency and reduction of vehicle weight have been prioritized in the automotive industry. Metal and glass are being increasingly replaced by resins in order to minimize the weight of automotive components like frames, windows and body parts. Different kinds of resins, especially polycarbonate, have been extensively utilized in parts such as hubcaps and door handles. Manufacturers are looking forward to use resins for larger components that include fenders and rear doors, as there is an increasing demand for lightweight vehicles. Thus, new resin from Teijin will gain a strong market in view of these reasons.

Green chemistry has a main theme of minimizing the weight of automobiles. The company?s materials and technologies aid in saving and improving the global environment.

Treating HIV and preventing it at the same time

Treatment drugs can do more than improve the health of people with HIV: If administered early, medications can also reduce the spread of the disease to sexual partners and may help stem the AIDS epidemic. But many logistical hurdles stand in the way of making this strategy feasible, affordable and effective, according to experts writing in Tuesday's edition of the journal PLoS Medicine.

The medications in question are antiretroviral therapies, which prevent HIV from multiplying and drastically diminish the amount of virus circulating in the blood. This not only curbs HIV's assault on the immune system, it also makes it much more difficult for an infected person to pass the virus to someone else.

This dual benefit was recognized last year in a landmark study finding that people with HIV who received treatment early on, before their immune systems encountered much damage, were 96% less likely to transmit the virus to their heterosexual partners than those who received treatment later in the course of the disease, when drug treatment is usually initiated.

One important implication was that HIV treatment and prevention efforts didn't have to compete for resources, said Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health. The study prompted AIDS experts to rethink their approach to preventing the virus' spread. Science magazine named it the "breakthrough of the year."

But capitalizing on this discovery may prove more difficult than some had hoped. Experts are now divided about whether the treatment-as-prevention approach can essentially halt the AIDS epidemic.

"The field is split about whether it's really the best thing and it's going to stop transmission, or if it's a small part of the puzzle," said Timothy Hallett, an infectious disease epidemiologist at Imperial College London, who co-wrote one of the new studies.

The real-world experience of public health officials in San Francisco, British Columbia, France and Australia ? four places where HIV testing and drug therapy are already common ? make clear that simply handing out pills won't be enough to beat back the virus, according to one of the studies.

Australia probably represents a best-case scenario, since antiretroviral drugs are freely available in that country and about 70% of people with HIV take the medication. But even there, the number of new HIV diagnoses has increased from 700 per year in 1999 to 1,000 per year in 2011, said study author David Wilson, an epidemiologist at the University of New South Wales in Sydney.

Early treatment "can have an impact, but it's not going to eradicate HIV," he said. "It's not the magic bullet."

For treatment to double as prevention, people need to get tested for HIV on a regular basis, start antiretroviral treatment once they test positive, and swallow pills for the rest of their lives to manage their viral load. Failure to follow through at any of these stages greatly reduces the drugs' ability to block transmission, Wilson said.

Making matters worse, people on the medication may stop taking other preventive measures, like using condoms, he added.

Biology and behavior are only two aspects of the treatment-as-prevention strategy that were examined in the PLoS Medicine studies. Some of the papers addressed economic considerations, including how long it would take for expenditures on antiretroviral drugs to pay for themselves by preventing costly treatments in people who remain HIV-free. The answer to that question is important for policymakers who are working with limited budgets.

Study authors also suggested that public health officials prioritize getting drugs to sex workers (who could spread the virus widely if untreated) and pregnant women (to reduce transmission to babies and deaths of mothers), among other groups. However, the authors noted the paucity of data available to evaluate whether these are the right groups to target.

Fauci, who didn't work on the new studies, said a primary objective was reaching and treating people who didn't know they were infected with HIV, since they unwittingly transmitted the majority of new HIV cases each year.

Public health officials in Los Angeles County, which has the country's second-largest concentration of HIV-positive people, hope to make testing a routine part of healthcare services to reach such individuals. Mario Perez, director of the county's HIV and sexually transmitted disease programs, called early treatment a "cornerstone" of the HIV prevention program.

"Getting a much higher proportion of residents living with HIV to be on treatment is going to be crucial to getting ahead of the epidemic," he said. "If we don't do that, I think we're going to continue to limp along with trying to prevent HIV infection."

And while the costs of drug treatment are much lower than they used to be, thanks in part to the development of generic alternatives to expensive name-brand drugs, other prevention methods like circumcision and condom distribution are far less costly.

Experts emphasized that early drug treatment should not be seen as a replacement for other preventive measures.

Though the strategy faces many uncertainties, Fauci said one thing was clear: "Biologically, it absolutely works." And if it can be successfully implemented, he said, "it would be an absolutely critical part of turning around the trajectory of the AIDS pandemic, in this country and worldwide."
