No discipline has been impacted more by war and armed conflict than health care has. Health systems and health care providers are often the first victims, suffering increasingly heinous acts that cripple the essential health delivery and public health infrastructure necessary for the protection of civilian and military victims of the state at war. This commentary argues that current instructional opportunities to prepare health care providers fall short in both content and preparation, especially in those operational skill sets necessary to manage multiple challenges, threats, and violations under international humanitarian law and to perform triage management in a resource-poor medical setting. Utilizing a historical framework, the commentary addresses the transformation of the education and training of humanitarian health professionals from the Cold War to today followed by recommendations for the future.

Since 1945, the reason for humanitarian crises and the way in which the world responds to them has dramatically changed every 10 to 15 years or less. Planning, response, and recovery for these tragic events have often been ad hoc, inconsistent, and insufficient, largely because of the complexity of global humanitarian demands and their corresponding response system capabilities. This historical perspective chronicles the transformation of war and armed conflicts from the Cold War to today, emphasizing the impact these events have had on humanitarian professionals and their struggle to adapt to increasing humanitarian, operational, and political challenges. An unprecedented independent United Nations–World Health Organization decision in the Battle for Mosul in Iraq to deploy to combat zones emergency medical teams unprepared in the skills of decades-tested war and armed conflict preparation and response afforded to health care providers and dictated by International Humanitarian Law and Geneva Convention protections has abruptly challenged future decision-making and deployments.

Radiocarbon measurements in tree rings can be used to estimate atmospheric 14C concentration and thereby used to create a 14C calibration curve. When wood is discovered in construction sites, rivers, buildings, and lake sediments, it is unclear if the wood could fill gaps in the 14C calibration curve or if the wood is of historical interest until the age is determined by dendrochronology or 14C dating. However, dendrochronological dating is subjected to many requirements and 14C dating is costly and time consuming, both of which can be frivolous endeavors if the samples are not in the age range of interest. A simplified 14C dating technique, called Speed Dating, was thus developed. It can be used to quickly obtain 14C ages as wood samples are neither chemically treated nor graphitized. Instead, wood is combusted in an elemental analyzer (EA) and the CO2 produced is carried into an accelerator mass spectrometer (AMS) with a gas ion source. Within a day, 75 samples can be measured with uncertainties between 0.5–2% depending on the age, preservation, and contaminants on the material and Speed Dating costs about one-third of conventional AMS dates.

The collaborative London based non-governmental organization network ELRHA (Enhancing Learning and Research for Humanitarian Assistance) supports partnerships between higher education institutions and humanitarian organizations worldwide with the objective to enhance the professionalization of the humanitarian sector. While coordination and control of the humanitarian sector has plagued the response to every major crisis, concerns highlighted by the 2010 Haitian earthquake response further catalyzed and accelerated the need to ensure competency-based professionalization of the humanitarian health care work force. The Harvard Humanitarian Initiative sponsored an independent survey of established academically affiliated training centers in North America that train humanitarian health care workers to determine their individual training center characteristics and preferences in the potential professionalization process. The survey revealed that a common thread of profession-specific skills and core humanitarian competencies were being offered in both residential and online programs with additional programs offering opportunities for field simulation experiences and more advanced degree programs. This study supports the potential for the development of like-minded academic affiliated and competency-based humanitarian health programs to organize themselves under ELRHA's regional “consultation hubs” worldwide that can assist and advocate for improved education and training opportunities in less served developing countries.

Limb amputations are frequently performed as a result of trauma inflicted during conflict or disasters. As demonstrated during the 2010 earthquake in Haiti, coordinating care of these patients in austere settings is complex. During the 2011 Humanitarian Action Summit, consensus statements were developed for international organizations providing care to limb amputation patients during disasters or humanitarian emergencies. Expanded planning is needed for a multidisciplinary surgical care team, inclusive of surgeons, anesthesiologists, rehabilitation specialists and mental health professionals. Surgical providers should approach amputation using an operative technique that optimizes limb length and prosthetic fitting. Appropriate anesthesia care involves both peri-operative and long-term pain control. Rehabilitation specialists must be involved early in treatment, ideally before amputation, and should educate the surgical team in prosthetic considerations. Mental health specialists must be included to help the patient with community reintegration. A key step in developing local health systemsis the establishment of surgical outcomes monitoring. Such monitoring can optimizepatient follow-up and foster professional accountability for the treatment of amputation patients in disaster settings and humanitarian emergencies.

The provision of surgery within humanitarian crises is complex, requiring coordination and cooperation among all stakeholders. During the 2011 Humanitarian Action Summit best practice guidelines were proposed to provide greater accountability and standardization in surgical humanitarian relief efforts. Surgical humanitarian relief planning should occur early and include team selection and preparation, appropriate disaster-specific anticipatory planning, needs assessment, and an awareness of local resources and limitations of cross-cultural project management. Accurate medical record keeping and timely follow-up is important for a transient surgical population. Integration with local health systems is essential and will help facilitate longer term surgical health system strengthening.

The melt-dilute treatment technology program is focused on the development and implementation of a treatment technology for diluting highly enriched (>20% 235U) aluminum spent nuclear fuel to low enriched levels (<20% 235U and qualifying the LEU Al-SNF form for geologic repository storage. In order to reduce the enrichment of these assemblies prior to ultimate geologic repository disposal, the melt-dilute technology proposes to melt these SNF assemblies and then dilute with additions of depleted uranium. The benefits accrued from this treatment process include the potential for significant volume reduction, reduced criticality potential, and the potential for enhanced SNF form characteristics. The emphasis within the development program to date has been on determining the process metallurgy and off-gas system design for the treatment of all types of Al SNF (UAIx, Al-U3O8, and AI-U3Si2). In determining the process metallurgy a wide range of alloys, representative of those expected in the Al-SNF form, have been fabricated and their product characteristics, namely microstructure, homogeneity, phase composition, and “ternary” constituent effects have been analyzed. As a result of the presence of species within the melt which will possess significant vapor pressures in the desired operating temperature range an off-gas system is necessary. Of the volatile species the one of greatest concern is 137Cs.

In the etiology of teleological functions, what role can be played by accidental occurrences? Douglas Ehring's essay “Accidental Functions” constructs a theory of ideological functions which makes it possible for objects to have functions even when their causal origins are due entirely to accident—be they natural functions (the function of the heart) or artifact functions (the function of a watch). Ehring constructs this view on the basis of a set of putative counterexamples aimed largely at the theories of Enc and Adams. Both of these theories block the attribution of ideological function to structures with entirely accidental causal histories—accidental in origin and in the way their effects are causally sustained.

This introduction and the three essays that follow it examine ambulatory cardiac monitoring for specific clinical indications. They also examine the ways in which evidence from the literature may be synthesized through the framework of decision analysis to guide its appropriate use and identify areas in which more research is needed. The essays discuss ambulatory cardiac monitoring for evaluation of syncope in the elderly; detection of silent ischemia after a myocardial infarction; and selection of antiarrhythmic drugs for malignant ventricular arrhythmias.

Dominant users of Lake Okeechobee water resources are agricultural producers and recreational anglers These uses will be directly affected, should the lake become infested with zebra mussels. We employ a probabilistic bioeconomic simulation model to estimate the potential impact of zebra mussels on consumptive water uses, recreational angling, and wetland ecosystem services under alternative public management scenarios. Without public management, the expected net economic impact from zebra mussels is –$244.1 million over 20 years. Public investment in prevention and eradication will yield a net expected gain of +$188.7 million, a superior strategy to either prevention or eradication alone.

We obtained information about the behavioral, psychiatric, and functional status of 26 children (13 males, 13 females) with juvenile neuronal ceroid lipofuscinosis (JNCL; mean age 12y 3mo [SD 3y 4mo]; range 6y 9mo to 18y 8mo). Twenty-five children had visual impairment and 18 were known to have a positive seizure history before enrollment. Parents completed the Child Behavior Checklist, Scales of Independent Behavior – Revised, and a structured interview to assess obsessive–compulsive symptoms. Participants exhibited a broad range of behavioral and psychiatric problems, rated as occurring frequently and/or as severe in more than half of the sample. Males and females did not differ with regard to the number of behavioral and psychiatric problems. Children were also limited in their ability to perform activities of daily living, including self-care, hygiene, socialization, and other age-appropriate tasks. Results provide a quantitative baseline for behavioral and psychiatric problems and functional level in JNCL, against which further decline can be measured. Longitudinal assessment of behavioral and psychiatric symptoms and functional abilities is continuing and will provide much-needed data on the natural history of JNCL.

Valid reviews of the effects of mental health care depend on identifying as high a proportion as possible of relevant randomized controlled trials (RCTs). To investigate the sensitivity and precision both of MEDLINE and of hand-searching for RCTs in mental health, 12 journals specializing in mental health and indexed by the National Library of Medicine (NLM) for MEDLINE were searched for the years 1971, 1976, 1981, 1986 and 1991. The sensitivity of the hand-search was 94% (95% Confidence Interval (CI) 93–95%), but it had a precision of only 7% (CI 6–8%). The optimal MEDLINE search had a sensitivity of only 52% (CI 48–56%) and precision of 59% (CI 55–63%). Of the reports of RCTs identified by the hand-search, 9% (CI 7–11 %) were not included in MEDLINE at all. Authors had included methodological descriptions in 84% (CI 80–88%) of RCTs found by the hand-search but missed by the MEDLINE search. Systematic reviews of mental health care which are based solely on MEDLINE searches of the literature will miss a large proportion of the relevant RCTs, and are thus liable to random error and bias. A register of mental health RCTs is urgently required.
