Many people naturally assume that the claims made for foods and nutritional supplements have the same degree of scientific grounding as those for medication, but that is not always the case. The IOM recommends that the FDA adopt a consistent scientific framework for biomarker evaluation in order to achieve a rigorous and transparent process.
There are four new publications on the NAP.edu site this week, all four of which have free PDFs to download.
As a quick reminder, we run down the list of new publications here at Notes From NAP every Monday, and we periodically highlight books related to current events and spotlight changes and features of our website. You can subscribe to all posts on Notes From NAP via the RSS feed or delivered by email.
The Food and Drug Administration (FDA) now requires that all clinical trials for drugs that affect the central nervous system–including psychiatric drugs–are assessed for whether that drug might cause suicidal ideation or behavior. The IOM’s Forum on Neuroscience and Nervous System Disorders hosted a meeting on June 26, 2009, to discuss the FDA’s new policy and how to analyze best whether suicidal thoughts predict actual suicidal behavior in the near future.
Teachers make a difference. The success of any plan for improving educational outcomes depends on the teachers who carry it out and thus on the abilities of those attracted to the field and their preparation. Yet there are many questions about how teachers are being prepared and how they ought to be prepared. Yet, teacher preparation is often treated as an afterthought in discussions of improving the public education system.
Preparing Teachers addresses the issue of teacher preparation with specific attention to reading, mathematics, and science. The book evaluates the characteristics of the candidates who enter teacher preparation programs, the sorts of instruction and experiences teacher candidates receive in preparation programs, and the extent that the required instruction and experiences are consistent with converging scientific evidence. Preparing Teachers also identifies a need for a data collection model to provide valid and reliable information about the content knowledge, pedagogical competence, and effectiveness of graduates from the various kinds of teacher preparation programs.
Federal and state policy makers need reliable, outcomes-based information to make sound decisions, and teacher educators need to know how best to contribute to the development of effective teachers. Clearer understanding of the content and character of effective teacher preparation is critical to improving it and to ensuring that the same critiques and questions are not being repeated 10 years from now.
Reducing the intake of sodium is an important public health goal for Americans. Since the 1970s, an array of public health interventions and national dietary guidelines has sought to reduce sodium intake. However, the U.S. population still consumes more sodium than is recommended, placing individuals at risk for diseases related to elevated blood pressure.
Strategies to Reduce Sodium Intake in the United States evaluates and makes recommendations about strategies that could be implemented to reduce dietary sodium intake to levels recommended by the Dietary Guidelines for Americans. The book reviews past and ongoing efforts to reduce the sodium content of the food supply and to motivate consumers to change behavior. Based on past lessons learned, the book makes recommendations for future initiatives. It is an excellent resource for federal and state public health officials, the processed food and food service industries, health care professionals, consumer advocacy groups, and academic researchers.

Since genetically engineered (GE) crops were introduced in 1996, their use in the United States has grown rapidly, accounting for 80-90 percent of soybean, corn, and cotton acreage in 2009. To date, crops with traits that provide resistance to some herbicides and to specific insect pests have benefited adopting farmers by reducing crop losses to insect damage, by increasing flexibility in time management, and by facilitating the use of more environmentally friendly pesticides and tillage practices. However, excessive reliance on a single technology combined with a lack of diverse farming practices could undermine the economic and environmental gains from these GE crops. Other challenges could hinder the application of the technology to a broader spectrum of crops and uses.
Several reports from the National Research Council have addressed the effects of GE crops on the environment and on human health. However, The Impact of Genetically Engineered Crops on Farm Sustainability in the United States is the first comprehensive assessment of the environmental, economic, and social impacts of the GE-crop revolution on U.S. farms. It addresses how GE crops have affected U.S. farmers, both adopters and nonadopters of the technology, their incomes, agronomic practices, production decisions, environmental resources, and personal well-being. The book offers several new findings and four recommendations that could be useful to farmers, industry, science organizations, policy makers, and others in government agencies.
There were two new publications this week, so we thought we’d give them both the featured publication treatment. If you’re looking for more books, we have plenty. Check our topics page for more in health and medicine and many other topics.
During public health emergencies such as pandemic influenza outbreaks or terrorist attacks, effective vaccines, drugs, diagnostics, and other medical countermeasures are essential to protecting national security and peoples’ well-being. The Public Health Emergency Medical Countermeasures Enterprise (PHEMCE–a partnership among federal, state, and local governments; industry; and academia–is at the forefront of the effort to develop and manufacture these countermeasures. However, despite the PHEMCE’s many successes, there are still serious challenges to overcome. Government-funded medical research is not always focused on countermeasures for the most serious potential threats, and it is difficult to engage pharmaceutical and biotechnology companies to develop and manufacture medical countermeasures that have a limited commercial market.
At the request of the Secretary of the U.S. Department of Health and Human Services and the Assistant Secretary for Preparedness and Response, the IOM held a workshop February 22-24, 2010, to address challenges facing the PHEMCE. Workshop participants discussed federal policies and procedures affecting the research, development, and approval of medical countermeasures and explored opportunities to improve the process and protect Americans’ safety and health.
For the United States, the1991 Persian Gulf War was a brief and successful military operation with few injuries and deaths. However, soon after returning from duty, a large number of veterans began reporting health problems they believed were associated with their service in the Gulf. At the request of Congress, the IOM is conducting an ongoing review of the evidence to determine veterans’ long-term health problems and what might be causing those problems. The fourth volume in the series, released in 2006, summarizes the long-term health problems seen in Gulf War veterans. In 2008, the IOM began an update to look at existing health problems and identify possible new ones, considering evidence collected since the initial summary.
In this report, the IOM determines that Gulf War service causes post-traumatic stress disorder (PTSD) and that service is associated with multisymptom illness; gastrointestinal disorders such as irritable bowel syndrome; alcohol and other substance abuse; and anxiety disorders and other psychiatric disorders. To ensure that our veterans receive the best possible care, now and in the future, the government should continue to monitor their health and conduct research to identify the best treatments to assist Gulf War veterans still suffering from persistent, unexplained illnesses.
Nearly 1.9 million U.S. troops have been deployed to Afghanistan and Iraq since October 2001. Many service members and veterans face serious challenges in readjusting to normal life after returning home. This initial book presents findings on the most critical challenges, and lays out the blueprint for the second phase of the study to determine how best to meet the needs of returning troops and their families.
Nine new publications—both pre-publications and final versions—hit the website last week, and as usual, we’re rounding them up here. Stay tuned to Notes From NAP. In the next few weeks, we’ll be writing about some of our most popular publications in addition to these weekly lists of what’s new.
During medical emergencies, hospital staff and emergency medical services (EMS) providers, can face barriers in delivering the fastest and best possible care. Overcrowded emergency rooms cannot care for patients as quickly as necessary, and some may divert ambulances and turn away new patients outright. In many states, ambulance staff lacks the means to determine which hospitals can provide the best care to a patient. Given this absence of knowledge, they bring patients to the closest hospital. In addition, because emergency service providers from different companies compete with each other for patients, and emergency care legislation varies from state to state, it is difficult to establish the necessary local, interstate, and national communication and collaboration to create a more efficient system.
In 2006, the IOM recommended that the federal government implement a regionalized emergency care system to improve cooperation and overcome these challenges. In a regionalized system, local hospitals and EMS providers would coordinate their efforts so that patients would be brought to hospitals based on the hospitals’ capacity and expertise to best meet patients’ needs. In September 2009, three years after making these recommendations, the IOM held a workshop sponsored by the federal Emergency Care Coordination Center to assess the nation’s progress toward regionalizing emergency care. The workshop brought together policymakers and stakeholders, including nurses, EMS personnel, hospital administrators, and others involved in emergency care. Participants identified successes and shortcomings in previous regionalization efforts; examined the many factors involved in successfully implementing regionalization; and discussed future challenges to regionalizing emergency care. This document summarizes the workshop.
It’s Monday, so we’re doing our usual roundup of the publications that were new to the nap.edu catalog in the last week. As with many of our publications, all of the new publications this week have PDFs available to download for free.
The world’s nations are moving toward agreements that will bind us together in an effort to limit future greenhouse gas emissions. With such agreements will come the need for all nations to make accurate estimates of greenhouse gas emissions and to monitor changes over time. In this context, the present book focuses on the greenhouse gases that result from human activities, have long lifetimes in the atmosphere and thus will change global climate for decades to millennia or more, and are currently included in international agreements. The book devotes considerably more space to CO2 than to the other gases because CO2 is the largest single contributor to global climate change and is thus the focus of many mitigation efforts. Only data in the public domain were considered because public access and transparency are necessary to build trust in a climate treaty.
The book concludes that each country could estimate fossil-fuel CO2 emissions accurately enough to support monitoring of a climate treaty. However, current methods are not sufficiently accurate to check these self-reported estimates against independent data or to estimate other greenhouse gas emissions. Strategic investments would, within 5 years, improve reporting of emissions by countries and yield a useful capability for independent verification of greenhouse gas emissions reported by countries.

We have a slight change to Notes From NAP: the weekly list of new publications on our site will now be on Mondays rather than the end of the day on Friday. As always, anyone interested in staying informed of the new books on the day they’re published can subscribe to the New From NAP RSS feed.
Suborbital flight activities, including the use of sounding rockets, aircraft, and high-altitude balloons, and suborbital reusable launch vehicles, offer valuable opportunities to advance science, train the next generation of scientists and engineers, and provide opportunities for participants in the programs to acquire skills in systems engineering and systems integration that are critical to maintaining the nation’s leadership in space programs. Furthermore, the NASA Authorization Act of 2008 finds it in the national interest to expand the size of NASA’s suborbital research program and to consider increased funding.
The Space Studies Board assessed the current state and potential of NASA’s suborbital research programs and conduct a review of NASA’s capabilities in this area. The scope of this review included: existing programs that make use of suborbital flights; the status, capability, and availability of suborbital platforms; the existing or planned launch facilities for suborbital missions; and opportunities for scientific research, training, and educational collaboration in the conduct of suborbital missions by NASA.
The findings were that suborbital program elements–airborne, balloon, and sounding rockets–play vital and necessary strategic roles in NASA’s research, innovation, education, employee development, and spaceflight mission success, thus providing the foundation for achievement of agency goals.
