A prospective, longitudinal analysis of musculoskeletal combat injuries sustained by a large combat-deployed maneuver unit has not previously been performed. A detailed description of the musculoskeletal combat casualty care statistics, distribution of wounds, and mechanisms of injury incurred by a US Army Brigade Combat Team during "The Surge" phase of Operation Iraqi Freedom was performed using a centralized casualty database and an electronic medical record system. Among the 4,122 soldiers deployed, there were 242 musculoskeletal combat wounds in 176 combat casualties. The musculoskeletal combat casualty rate for the Brigade Combat Team was 34.2 per 1,000 soldier combat-years. Spine, pelvis, and long bone fractures comprised 55.9% (33 of 59) of the total fractures sustained in combat. Explosions accounted for 80.7% (142 of 176) of all musculoskeletal combat casualties. Musculoskeletal combat casualty wound incidence rates per 1,000 combat-years were as follows: major amputation, 2.1; minor amputation, 0.6; open fracture, 5.0; closed fracture, 6.4; and soft-tissue/neurovascular injury, 32.8. Among musculoskeletal combat casualties, the likelihood of a gunshot wound causing an open fracture was significantly greater (45.8% [11 of 24]) when compared with explosions (10.6% [15 of 142]) (p = 0.0006). Long bone amputations were more often caused by explosive mechanisms than gunshot wounds. A large burden of complex orthopedic injuries has resulted from the combat experience in Operation Iraqi Freedom. This is because of increased enemy reliance on explosive devices, the use of individual and vehicular body armor, and improved survivability of combat-injured soldiers.

The Small Unmanned Aircraft System (SUAS) is a rucksack portable aerial observation vehicle designed to supplement reconnaissance, surveillance and target acquisition tasks of an infantry company. The Raven is an earlier version of the SUAS. Raven is an Urgent Material Release (UMR) acquisition and has been used for the past two years by selected Army units in Operations Enduring Freedom and Iraqi Freedom (OEF/OIF). Army Test and Evaluation Command-led surveys were used to assess the capabilities and limitations of the Raven in OEF/OIF. Results and analyses of the surveys indicate that Raven enhances situational awareness of a small unit in urban areas and in selected close combat missions. Users of the Raven state it is easy to use, although there are major issues with frequency de-confliction, airspace management, short endurance, and sensor performance. The SUAS is a program of record and completed developmental and operational testing in preparation for full rate production. This paper addresses the SUAS effectiveness, suitability, and survivability evaluation strategy based on actual testing of the system. During the Initial Operational Test (IOT), the SUAS was found to be effective with limitations in a set of 21 closed combat missions and two call for fire tests for which it was tested. Low Mean Time Between Operational Mean Failure (MTBOMF) and human factors issues make the system suitable with limitations. Acoustic (audible to the human ear) and electronic vulnerabilities make the system non-survivable in most combat scenarios. The SUAS was found to be useful as an extra asset usable in certain infantry company close combat missions where terrain and visual line of sight give the system an advantage over traditional reconnaissance patrols. Army aviation and infantry units uncover new ways every day to use this portable "eye in the sky", especially when unmanned aerial reconnaissance assets are in premium demand. A discussion on changes in doctrine with the SUAS and how it will be integrated into future combat systems for the Army completes the evaluation analysis and its likely benefits to the Soldier.

Females have been restricted from serving in direct combat arms' positions for decades. One reason for the exclusion derives from the perceived physical demands of these positions. As a result, many current efforts are directed toward defining the physical demands of combat arms' positions. The purpose of this study was to develop a physical performance and body composition profile of females who could overcome the physical demands of combat tasks that rely primarily on upper body strength. This study is based on an analysis of archival data from 2 separate samples of active-duty female Marines (n = 802), who had been recruited to participate in heavy lifting tasks. These tasks included lifting a heavy machine gun (HMG) lift (cohort 1, n = 423) and Clean and Press lifts (29.5-52.3 kg) (cohort 2, n = 379). To develop the physical performance profile, data from annual physical fitness tests were collected, which included run times, ammunition can lift, 804. Seven-meter (880-yard) movement to contact, and the maneuver under fire. In cohort 1, 65 females (∼15%; n = 423 females) successfully completed HMG; in cohort 2, 33 females (∼9%; n = 379 females) successfully completed another strength task, a Clean and Press of 52.3 kg. In both samples, female Marines who were successful on these tasks also outperformed their unsuccessful counterparts on the annual physical fitness tests. In addition, larger females typically outperformed their smaller counterparts. Females seeking assignment to closed combat arms' positions would thus be well served by targeting upper body strength, while maintaining overall physical fitness.

Caffeine is one of the ergogenic substances most used by warfighters in current operation areas, but the effect on the organic response and operational performed is already poor knowledge. This research aimed to study the acute effect of 400 mg of caffeine monohydrate on the psycho-physiological response and rifle marksmanship of warfighters during a close quarter combat simulation. We analysed parameter of heart rate, blood lactate, cortical arousal, state anxiety and marksmanship of 20 Spanish Army veteran warfighters before and after a close quarter combat simulation in a double-blind procedure, also a correlation analysis was conducted between all the study variables. Marksmanship of warfighters did not improve with the caffeine ingestion, but it produced an increase in blood lactate concentration (caffeine: 1.9 ± 0.5 vs. 9.2 ± 1.1 mmol.l -1 ; placebo: 1.8 ± 0.7 vs. 6.9 ± 2.2 mmol.l -1 ), cortical arousal (% of change: caffeine: 2.51; placebo: -1.96) and heart rate (caffeine: 80.0 ± 7.2 vs. 172.9 ± 28.2 bpm; placebo: 79.3 ± 6.4 vs. 154.0 ± 26.8 bpm). In addition, higher heart rate values correlated negatively with marksmanship in close quarter combat. We concluded that caffeine intake did not improve the warfighters rifle marksmanship in close quarter combat possibly due to the increase in the physiological response.

The en route care environment is dynamic and requires constant innovation to ensure appropriate nursing care for combat casualties. Building on experiences in Iraq and Afghanistan, there have been tremendous innovations in the process of transporting patients, including the movement of patients with spinal injuries. Advances have also been made in pain management and noninvasive monitoring, particularly for trauma and surgical patients requiring close monitoring of their hemodynamic and perfusion status. In addition to institutionalizing these innovations, future efforts are needed to eliminate secondary insults to patients with traumatic brain injuries and technologies to provide closed-loop sedation and ventilation.

For decades women have been restricted from direct assignment to certain military occupational specialties such as infantry. These restrictions can limit the advancement of women through the ranks of military leadership. Thus, the purpose of this effort was to identify those physical requirements most likely to serve as barriers for women wanting to enter closed combat arms positions, and to evaluate the quality of existing physical fitness tests as potential measures of assessment of combat readiness. Data were collected from 3 different sites within the US Marine Corps Training and Education Command. All participants (409 male, 379 femaile) were active-duty Marines who recently completed the Physical Fitness Test (PFT) and Combat Fitness Test (CFT). Participants completed 6 physical tasks: 120-mm tank loading drill, 155-mm artillery round carry, negotiating an obstacle course wall while wearing a fighting load (≈30 lb), pull-ups, deadlift, and clean and press. Overall, there was a high rate of successful completion on the combat proxy tasks (men, ≈80% to 100%; women, ≈70% to 100%), with the notable exception being the clean and press (men, 80%; women, 9%) and pull-ups (men, 16±4; women, 4±2). The PFT and CFT components tasks were also related, strongly in some cases, with performance on combat-related proxy tasks (Spearman's ρ typically ranged from 0.60 to 0.80). Estimates of fat-free mass and VO2max were also strongly related to an overall measure of combat readiness (Spearman's ρ=0.77 and ρ=0.56, respectively). The primary physical obstacle for women is upper body strength. However, some women could successfully complete all of the proxy tasks and thus are physically capable of meeting the demands of closed combat occupations. The fact that some female Marines could complete the most challenging upper body strength tasks suggests that these barriers are not inherent but may be due to a lack of training specificity.

A 17-year-old patient was aggressively attacked and stabbed in the dorsal region of his back by a knife. He was admitted to the emergency room of the Hammoud Hospital University Medical Center, Saida, Lebanon lying in the prone position. The neurological examination revealed that the stabbing object was fixed at the dorsal spine level at the T-7 level, where it was inserted inside the vertebral body. Luckily, the blade of the knife was parallel to the nervous tracts of the spinal cord; thus, he showed no neurological deficits. This case provides an overview of how neurosurgical principles can be applied to trauma patients with spine injuries due to close combat weapons.

The present study examined the normative scores and psychometric properties of the Personality Assessment Inventory (PAI; Morey, 1991) within a non-treatment-seeking sample of soldiers deployed to combat zones in Iraq, compared with a sample of community adults matched with respect to age and gender. Results indicate the scores and properties of the PAI scales were generally quite similar in the Iraq and community samples, with modest differences emerging on only 3 subscales addressing antisocial behavior, issues with close relationships, and interpersonal vigilance. These results suggest that standard normative interpretation of PAI scales is appropriate even when the instrument is administered in a combat zone. In comparison with prior research, the results may suggest that documented mental health issues among combat veterans, when present, may be particularly likely to emerge postdeployment. 2011 APA, all rights reserved

Combat-related acetabular fractures: Outcomes of open versus closed injuries.

2018-02-01

Since the onset of the Global War on Terror close to 50,000 United States service members have been injured in combat, many of these injuries would have previously been fatal. Among these injuries, open acetabular fractures are at an increased number due to the high percentage of penetrating injuries such as high velocity gunshot wounds and blast injuries. These injuries lead to a greater degree of contamination, and more severe associated injuries. There is a significantly smaller proportion of the classic blunt trauma mechanism typically seen in civilian trauma. We performed a retrospective review of the Department of Defense Trauma Registry into which all US combat-injured patients are enrolled, as well as reviewed local patient medical records, and radiologic studies from March 2003 to April 2012. Eighty seven (87) acetabular fractures were identified with 32 classified as open fractures. Information regarding mechanism of injury, fracture pattern, transfusion requirements, Injury Severity Score (ISS), and presence of lower extremity amputations was analyzed. The mechanism of injury was an explosive device in 59% (n=19) of patients with an open acetabular fracture; the remaining 40% (n=13) were secondary to ballistic injury. In contrast, in the closed acetabular fracture cohort 38% (21/55) of fractures were due to explosive devices, and all remaining (n=34) were secondary to blunt trauma such as falls, motor vehicle collisions, or aircraft crashes. Patients with open acetabular fractures required a median of 17units of PRBC within the first 24h after injury. The mean ISS was 32 in the open group compared with 22 in the closed group (p=0.003). In the open fracture group nine patients (28%) sustained bilateral lower extremity amputations, and 10 patients (31%) ultimately underwent a hip disarticulation or hemi-pelvectomy as their final amputation level. Open acetabular fractures represent a significant challenge in the management of combat-related injuries. High ISS and massive transfusion requirements are common in these injuries. This is one of the largest series reported of open acetabular fractures. Open acetabular fractures require immediate damage control surgery and resuscitation as well as prolonged rehabilitation due to their severity. The dramatic number of open acetabular fractures (37%) in this review highlights the challenge in treatment of combat related acetabular fractures. Published by Elsevier Ltd.

Combat ocular trauma and systemic injury.

To review the recent literature regarding combat ocular trauma during hostilities in Operations Iraqi Freedom and Enduring Freedom, describe the classification of combat ocular trauma, and offer strategies that may assist in the management of eye injuries. Several recent publications have highlighted features of combat ocular trauma from Operation Iraqi Freedom. The most common cause of today's combat ocular injuries is unconventional fragmentary munitions causing significant blast injuries. These explosive munitions cause high rates of concomitant nonocular injuries such as traumatic brain injury, amputation, and other organ injuries. The most frequent ocular injuries include open-globe and adnexal lacerations. The extreme severity of combat-related open-globe injuries leads to high rates of primary enucleation and retained intraocular foreign bodies. Visual outcomes of intraocular foreign body injuries are similar to other series despite delayed removal, and no cases of endophthalmitis have occurred. Despite these advances, however, significant vision loss persists in cases of perforating globe injuries as well as open and closed-globe trauma involving the posterior segment. This review summarizes the recent literature describing ocular and systemic injuries sustained during Operations Iraqi and Enduring Freedom. An emphasis on classification of ocular injuries as well as a discussion of main outcome measures and complications is discussed.

Repeated exposure to taekwondo combat modulates the physiological and hormonal responses to subsequent bouts and recovery periods. J Strength Cond Res XX(X): 000-000, 2018-This study examined the physiological and hormonal responses to successive taekwondo combats using an ecologically valid competition time structure. Ten elite male international taekwondo competitors (age 19 ± 3 years) took part in a simulated championship event. The competitors performed 4 combats that were interspersed with different recovery intervals (63 ± 4, 31 ± 3 and 156 ± 5 minutes, respectively). Heart rate (HR) was measured during the combats and venous blood samples were obtained both before and after each combat to determine the plasma metabolite and hormone concentrations. The plasma noradrenaline (21.8 ± 12.8 vs. 15.0 ± 7.0 nmol·l) and lactate (13.9 ± 4.2 vs. 10.5 ± 3.2 mmol·l) responses were attenuated (p < 0.05) between combat 1 and 4. Higher (p < 0.05) HR responses were evident in the final combat when compared with the earlier combats. Higher (p < 0.05) resting HR (139 ± 10 vs. 127 ± 12 b·min), plasma lactate (3.1 ± 1.2 vs. 2.0 ± 0.7 mmol·l), glycerol (131 ± 83 vs. 56 ± 38 μmol·l) and nonesterified free fatty acid (0.95 ± 0.29 vs. 0.71 ± 0.28 mmol·l) concentrations were measured before combat 3 compared with combat 1. Repeated exposure to taekwondo combat using an ecologically valid time structure modulates the physiological and hormonal responses to subsequent bouts and recovery periods. Strategies designed to assist competitors to effectively manage the metabolic changes associated with the fight schedule and promote recovery between the bouts may be important during championship events.

To improve the mortality rate on the battlefield, and especially the potentially survivable pre-Medical Treatment Facility deaths, Tactical Combat Casualty Care (TCCC) is now considered as a reference for management of combat casualty from the point of injury to the first medical treatment facility. TCCC comprises of a set of trauma management guidelines designed for use on the battlefield. The French Military Health Service also standardised a dedicated training programme, entitled "Sauvetage au Combat" (SC) ("forward combat casualty care"), with the characteristic of forward medicalisation on the battlefield, the medical team being projected as close as possible to the casualty at the point of injury. The aim of our article is to describe the process and the result of the SC training. Records from the French Military Health Service Academy - École du Val-de-Grâce administration, head of the SC teaching programme, defining its guidelines, and supporting its structure and its execution, were examined and analyzed, since the standardisation of the SC training programme in 2008. The total number of trainees was listed following the different courses (SC1, SC2, SC3). At the end of 2013, every deployed combatant underwent SC1 courses (confidential data), 785 health-qualified combatants were graduated for SC2 courses and 672 Role 1 physician-nurse pairs for SC3 courses. The SC concept and programmes were defined in France in 2007 and are now completely integrated into the predeployment training of all combatants but also of French Military Health Service providers. Finally, SC teaching programmes enhance the importance of teamwork in forward combat medicalisation settings. Copyright © 2014 Elsevier Ltd. All rights reserved.

War and remembrance: Combat exposure in young adulthood and memory function sixty years later.

Nevarez, Michael D; Malone, Johanna C; Rentz, Dorene M; Waldinger, Robert J

2017-01-01

Identifying adaptive ways to cope with extreme stress is essential to promoting long-term health. Memory systems are highly sensitive to stress, and combat exposure during war has been shown to have deleterious effects on cognitive processes, such as memory, decades later. No studies have examined coping styles used by combat veterans and associations with later-life cognitive functioning. Defenses are coping mechanisms that manage difficult memories and feelings, with some more closely related to memory processes (e.g., suppression, repression). Utilizing a longitudinal database, we assessed how reliance on certain defense mechanisms after World War II combat exposure could affect cognitive health 60years later. Data spanning 75years were available on 71 men who had post-war assessment of combat exposure, defense mechanism ratings (ages 19-50), and late-life neuropsychological testing. Interaction models of combat exposure with defenses predicting late-life memory were examined. In bivariate analyses, greater reliance on suppression correlated with worse memory performance (r=-0.30, p=.01), but greater reliance on repression did not. Greater reliance on suppression strengthened the link between combat exposure and worse memory in late life (R 2 =0.24, p<.001). In contrast, greater reliance on repression attenuated the link between combat exposure and poorer late-life memory (R 2 =0.19, p<.001). Results suggest that coping styles may affect the relationship between early-adult stress and late-life cognition. Findings highlight the importance of understanding how coping styles may impact cognitive functioning as people move through adult life. Copyright © 2016 Elsevier Inc. All rights reserved.

Smarter Drugs: How Protein Crystallography Revolutionizes Drug Design

DOE Office of Scientific and Technical Information (OSTI.GOV)

Smith, Clyde

2005-04-26

According to Smith, protein crystallography allows scientists to design drugs in a much more efficient way than the standard methods traditionally used by large drug companies, which can cost close to a billion dollars and take 10 to 15 years. 'A lot of the work can be compressed down,' Smith said. Protein crystallography enables researchers to learn the structure of molecules involved in disease and health. Seeing the loops, folds and placement of atoms in anything from a virus to a healthy cell membrane gives important information about how these things work - and how to encourage, sidestep or stopmore » their functions. Drug design can be much faster when the relationship between structure and function tells you what area of a molecule to target. Smith will use a timeline to illustrate the traditional methods of drug development and the new ways it can be done now. 'It is very exciting work. There have been some failures, but many successes too.' A new drug to combat the flu was developed in a year or so. Smith will tell us how. He will also highlight drugs developed to combat HIV, Tuberculosis, hypertension and Anthrax.« less

Enhancing US-Japan Cooperation to Combat Antimicrobial Resistance

PubMed Central

2014-01-01

The Global Health Security Agenda (GHSA) is aimed at preventing, detecting, and responding to infectious disease threats. To move toward these goals, the United States has committed to partner with at least 30 countries around the world. One of the objectives of the GHSA includes “[p]reventing the emergence and spread of antimicrobial drug resistant organisms.” Antimicrobial resistance (AMR) has become a growing global health security problem, with inappropriate use of antimicrobial medications in humans and animals and a lack of new antimicrobial medications contributing to this problem. While AMR is a growing global concern, working on it regionally can make this multifaceted problem more manageable. The United States and Japan, both world leaders in the life sciences, are close allies that have established cooperative programs in medical research and global health that can be used to work on combating AMR and advance the GHSA. Although the United States and Japan have cooperated on health issues in the past, their cooperation on the growing problem of AMR has been limited. Their existing networks, cooperative programs, and close relationships can and should be used to work on combating this expanding problem. PMID:25470465

Management of combat-related urological trauma in the modern era.

2013-09-01

Complex genitourinary injuries--associated with lower-extremity amputation as well as pelvic and abdominal wounding--have emerged as common occurrences in current military combat operations. The nature of combat injuries of the genitourinary tract is varied, as are the strategies used in their management. For example, 5% of all combat injuries include wounds of the urinary system or genitalia. For injuries that are predominantly penetrating in nature, immediate care requires the judicious preservation of viable tissue. Once the patient is stable, urethral, corporal and testicular lacerations are closed primarily, whereas soft tissue injuries are re-approximated in a delayed fashion. Negative-pressure dressings have been a useful aid in wound management; wound coverage is most commonly completed with split-thickness skin grafts and local flaps. Complex penile and urethral reconstructions are often delayed so orthopaedic injuries can heal and the patient can manage activities of daily living. Final reconstruction requires a urologist with a full understanding of reconstructive techniques.

Physical Training Strategies for Military Women's Performance Optimization in Combat-Centric Occupations.

PubMed

Nindl, Bradley C

2015-11-01

The physiological differences, particularly of upper-body strength and power, between women and men, and the rigors of combat-centric occupational demands would seem to place women at a significant disadvantage, as the U.S. military opens up previously closed combat-arms military occupational specialties (MOSs) to women. This inherent disadvantage can be significantly mitigated by implementing effective and comprehensive physical training (PT) regimens for women targeting those fitness components most critical for those tasks considered most essential for solider warfighting duties (i.e., strength and power). Regrettably, the military historical and legacy overemphasis on aerobic fitness and on "field expediency" as the major criteria for implementing training have limited the extent to which the military has fully operationalized state-of-the-science PT policies. This continued legacy approach could be problematic regarding fully enhancing women's abilities to perform physically demanding combat-centric occupations and could place the successful integration of women into ground combat MOSs at significant risk. Seminal studies from the literature indicate that (a) a minimum of 6 months of periodized combined resistance/endurance training preparedness is recommended for untrained women considering entering combat-arms MOS training; (b) any comprehensive PT program should incorporate and emphasize progressive load carriage training; (c) a greater emphasis on upper body on strength/power development in military women is needed; (d) heavy resistance training in the range of 3-8 repetition maximum sets should be incorporated into training programs to target type II motor units and muscle fibers (those fibers that produce the most force and have the greatest capacity to hypertrophy); (e) low-volume, high-intensity interval training should be considered as a time-efficient training method to improve aerobic fitness while protecting against lower-body musculoskeletal injuries; (f) flexible nonlinear periodized programs should be considered to best accommodate the unpredictability and operational functional needs of the military training environment; and (g) serious consideration should be given to revamping the manner in which the military conducts physical readiness training, with a departure from "field expediency" as the major criteria for determining PT policies. With an increased emphasis on the human dimension of soldiering and concerted strategic, operational, and tactical efforts to maximize individual physical readiness and performance, the science of training physiology exists to leverage and better physically prepare women as they enter more combat-centric occupations.

[Experimental studies on the wounding capacity of recently developed shuriken/throwing stars and their legal categorization--an interdisciplinary view].

Shuriken/throwing stars are traditional Japanese weapons for close combat situations. They vary greatly in shape and mode of action. Due to their wounding capacity traditional shuriken made of steel were prohibited in Germany in the 1980's. In the present study three recently developed types of shuriken were examined to determine their wounding capacity. Type 1 was made of plastic, whereas type 2 was a so-called cyclone shuriken equipped with three knives protruding from a discoidal center due to centrifugal force during the flight. Type 3 consisted of three traditional metal shuriken with blunt edges and peaks produced for decorative purposes. Experiments using pig carcasses were carried out for types 1 and 2. An experiment using human skin was performed with type 3 shuriken. An experienced thrower performed throws from a distance of 1, 2, 3, and 4 m with the shuriken made of plastic. For the cyclone shuriken a distance of 4 m was chosen to ensure the unfolding of the shuriken during flight. Type 3 shuriken were tested using a distance of 2 m. Penetration depths of the shuriken made of plastic reached up to 8 mm in pig skin. The experiment with the cyclone shuriken revealed a penetration depth of up to 2.5 cm cutting through the entire abdominal tissue and opening up an intestinal loop whereas type 3 shuriken yielded maximal penetration depths between 0.9 and 2.3 cm. This study indicates that all three types of shuriken may inflict lethal wounds upon opponents in close combat. The findings of this study should promote a public discussion whether the ban on traditional shuriken should be extended to the recently developed types.

Evaluation and management of combat-related spinal injuries: a review based on recent experiences.

PubMed

Schoenfeld, Andrew J; Lehman, Ronald A; Hsu, Joseph R

2012-09-01

The current approach to the evaluation and treatment of military casualties in the Global War on Terror is informed by medical experience from prior conflicts and combat encounters from the last 10 years. In an effort to standardize the care provided to military casualties in the ongoing conflicts, the Department of Defense (DoD) has published Clinical Practice Guidelines (CPGs) that deal specifically with the combat casualty sustaining a spinal injury. However, the combat experience with spine injuries in the present conflicts remains incompletely described. To describe the CPGs for the care of the combat casualty with suspected spine injuries and discuss them in light of the published military experience with combat-related spinal trauma. Literature review. A literature review was conducted regarding published works that discussed the incidence, epidemiology, and management of combat-related spinal trauma. The CPGs, established by the DoD, are discussed in light of actual military experiences with spine trauma, the present situation in the forward surgical teams and combat support hospitals treating casualties in theater, and recent publications in the field of spine surgery. In the conventional wars fought by the United States between 1950 and 1991 (Korea, Vietnam, Gulf War I), the incidence of spine injuries remained close to 1% of all combat casualties. However, in the Global War on Terror, the enemy has relied on implements of asymmetric warfare, including sniper attacks, ambush, roadside bombs, and improvised explosive devices. The increase in explosive mechanisms of injury has elevated the number of soldiers exposed to blunt force trauma and, consequently, recent publications reported the highest incidence of combat-related spinal injuries in American military history. Wounded soldiers are expeditiously evacuated through the echelons of care but typically do not receive surgical management in theater. The current CPGs for the care of soldiers with combat-related spinal injuries should be re-examined in light of data regarding the increasing number of spine injuries, new injury patterns, such as lumbosacral dissociation and low lumbar burst fractures, and recent reports within the field of spine surgery as a whole. American and coalition forces are sustaining the highest spine combat casualty rates in recorded history and previously unseen injuries are being encountered with increased frequency. While the CPGs provide useful direction in terms of the evaluation and management of combat casualties with spine injuries, such recommendations may warrant periodic re-evaluation in light of recent combat experiences and evolving scientific evidence within the spine literature.

In 2008, a clinical practice guideline (CPG) was developed for the prevention of infections among combat casualties and was later revised in 2011. We evaluated utilization of antimicrobials within 48 hours following injury in the combat zone over a five-year period (June 2009–May 2014) with regard to number of regimens, type of antimicrobial, and adherence to the 2011 CPG. The study population consisted of 5196 wounded military personnel. Open fractures and skin and soft-tissue injuries were the most frequent injuries. Closed injuries had the highest overall compliance (83%), while open fractures and maxillofacial injuries had significant improvement in compliance from 2009–2010 (34% and 50%, respectively) to 2013–2014 (73% and 76%; p<0.05). Part of the improvement with open fractures was a significant reduction of expanded Gram-negative coverage (61% received it in 2009–2010 compared to 7% in 2013–2014; p<0.001). Use of Gram-negative coverage with maxillofacial injuries also significantly declined (37% to 12%; p=0.001). Being injured during 2011–2014 compared to 2009–2010 was associated with CPG compliance (p<0.001), while high injury severity scores (≥10) and admission to the intensive care unit in Germany were associated with noncompliance (p<0.001). Our analysis demonstrates an increasing trend toward CPG compliance with significant reduction of expanded Gram-negative coverage. PMID:28291497

The current civilian Abbreviated Injury Scale (AIS), designed for automobile crash injuries, yields important information about civilian injuries. It has been recognized for some time, however, that both the AIS and AIS-based scores such as the Injury Severity Score (ISS) are inadequate for describing penetrating injuries, especially those sustained in combat. Existing injury coding systems do not adequately describe (they actually exclude) combat injuries such as the devastating multi-mechanistic injuries resulting from attacks with improvised explosive devices (IEDs). After quantifying the inapplicability of current coding systems, the Military Combat Injury Scale (MCIS), which includes injury descriptors that accurately characterize combat anatomic injury, and the Military Functional Incapacity Scale (MFIS), which indicates immediate tactical functional impairment, were developed by a large tri-service military and civilian group of combat trauma subject-matter experts. Assignment of MCIS severity levels was based on urgency, level of care needed, and risk of death from each individual injury. The MFIS was developed based on the casualty's ability to shoot, move, and communicate, and comprises four levels ranging from "Able to continue mission" to "Lost to military." Separate functional impairments were identified for injuries aboard ship. Preliminary evaluation of MCIS discrimination, calibration, and casualty disposition was performed on 992 combat-injured patients using two modeling processes. Based on combat casualty data, the MCIS is a new, simpler, comprehensive severity scale with 269 codes (vs. 1999 in AIS) that specifically characterize and distinguish the many unique injuries encountered in combat. The MCIS integrates with the MFIS, which associates immediate combat functional impairment with minor and moderate-severity injuries. Predictive validation on combat datasets shows improved performance over AIS-based tools in addition to improved face, construct, and content validity and coding inter-rater reliability. Thus, the MCIS has greater relevance, accuracy, and precision for many military-specific applications. Over a period of several years, the Military Combat Injury Scale and Military Functional Incapacity Scale were developed, tested and validated by teams of civilian and tri-service military expertise. MCIS shows significant promise in documenting the nature, severity and complexity of modern combat injury.

Mediation and Moderation of the Relationship Between Combat Experiences and Post-Traumatic Stress Symptoms in Active Duty Military Personnel.

PubMed

Steele, Marshall; Germain, Anne; Campbell, Justin S

2017-05-01

Post-traumatic stress disorder (PTSD) is a major health concern among the U.S. military population, affecting up to 12% to 24% of veterans returning from Iraq and Afghanistan. Sleep disturbances, neuroticism, and childhood trauma have all been associated with the development of PTSD in military populations, especially in relation to combat experiences. The effects of disrupted sleep and post-traumatic stress can affect the physical well-being of soldier and sailors in the field and impact them for years after deployment. This study aimed to evaluate the relationship between self-reported measures of combat experiences, PTSD symptoms, sleep, neuroticism, and childhood adversity in an active duty military population. 972 U.S. Navy Sailors serving in Afghanistan were given anonymous surveys that assess scales of combat stressors, PTSD symptoms, sleep problems, neuroticism, adverse child experiences (ACEs), and other covariates. Sleep disturbances were hypothesized as moderators, having an indirect effect on the relationship between combat experiences and PTSD symptoms. Neuroticism scores and ACEs were proposed as moderators of the combat-PTSD symptom relationship. Mediation and moderation models were developed and tested using logistic regressions. Increased number of combat experiences was found to be a significant predictor of PTSD, even when adjusting for all covariates (p < 0.05). Consistent with partial mediation, nightmares had an indirect effect on the relationship between combat experiences and PTSD symptoms in the final model (path coefficient = 0.233, 95% confidence interval = 0.036, 0.483). Neuroticism was an independent predictor of PTSD symptoms (p < 0.001), but the interaction of combat and neuroticism did not predict symptoms of PTSD. ACEs did not have a significant impact in the model as either an independent predictor or a moderating factor. These results indicate that the presence of nightmares may partially explain how traumatic combat experiences lead to the development of PTSD. The study also reaffirms neuroticism as risk factor for developing PTSD symptoms. These findings highlight the importance of sleep hygiene and operational stress models in combat situations and may help stress control professionals address risk factors associated with PTSD symptoms.

Optimizing the recovery efficiency of Finnish oil combating vessels in the Gulf of Finland using Bayesian Networks.

Oil transport has greatly increased in the Gulf of Finland over the years, and risks of an oil accident occurring have risen. Thus, an effective oil combating strategy is needed. We developed a Bayesian Network (BN) to examine the recovery efficiency and optimal disposition of the Finnish oil combating vessels in the Gulf of Finland (GoF), Eastern Baltic Sea. Four alternative home harbors, five accident points, and ten oil combating vessels were included in the model to find the optimal disposition policy that would maximize the recovery efficiency. With this composition, the placement of the oil combating vessels seems not to have a significant effect on the recovery efficiency. The process seems to be strongly controlled by certain random factors independent of human action, e.g. wave height and stranding time of the oil. Therefore, the success of oil combating is rather uncertain, so it is also important to develop activities that aim for preventing accidents. We found that the model developed is suitable for this type of multidecision optimization. The methodology, results, and practices are further discussed.

Medical capability team: the clinical microsystem for combat healthcare delivery in counterinsurgency operations.

2008-01-01

Today's operational environment in the support of counterinsurgency operations requires greater tactical and operational flexibility and diverse medical capabilities. The skills and organizations required for full spectrum medical operations are different from those of the past. Combat healthcare demands agility and the capacity for rapid change in clinical systems and processes to better support the counterinsurgency environment. This article proposes the Army Medical Department (AMEDD) develop and implement the medical capability team (MCT) for combat healthcare delivery. It discusses using the concept of the brigade combat team to develop medical capability teams as the unit of effectiveness to transform frontline care; provides a theoretical overview of the MCT as a "clinical microsystem"; discusses MCT leadership, training, and organizational support, and the deployment and employment of the MCT in a counterinsurgency environment. Additionally, this article proposes that the AMEDD initiate the development of an AMEDD Combat Training Center of Excellence to train and validate the MCTs. The complexity of combat healthcare demands an agile and campaign quality AMEDD with joint expeditionary capability in order to promote the best patient outcomes in a counterinsurgency environment.

Infrared imaging-based combat casualty care system

Davidson, James E., Sr.

1997-08-01

A Small Business Innovative Research (SBIR) contract was recently awarded to a start up company for the development of an infrared (IR) image based combat casualty care system. The company, Medical Thermal Diagnostics, or MTD, is developing a light weight, hands free, energy efficient uncooled IR imaging system based upon a Texas Instruments design which will allow emergency medical treatment of wounded soldiers in complete darkness without any type of light enhancement equipment. The principal investigator for this effort, Dr. Gene Luther, DVM, Ph.D., Professor Emeritus, LSU School of Veterinary Medicine, will conduct the development and testing of this system with support from Thermalscan, Inc., a nondestructive testing company experienced in IR thermography applications. Initial research has been done with surgery on a cat for feasibility of the concept as well as forensic research on pigs as a close representation of human physiology to determine time of death. Further such studies will be done later as well as trauma studies. IR images of trauma injuries will be acquired by imaging emergency room patients to create an archive of emergency medical situations seen with an infrared imaging camera. This archived data will then be used to develop training material for medical personnel using the system. This system has potential beyond military applications. Firefighters and emergency medical technicians could directly benefit from the capability to triage and administer medical care to trauma victims in low or no light conditions.

NASA Technical Reports Server (NTRS)

Hague, D. S.

1977-01-01

Computer simulations of the one-on-one aerial combat encounter are generated under the control of specified guidance laws. Given an initial state, the vehicle and atmospheric characteristics, and the guidance laws, the aerial combat encounter is simulated by forward integration of the two vehicles' motions. The development of a combat guidance law which converts positional advantage into an improved firing opportunity is reported. A combination of lag, line of sight, and lead pursuit steering paths are followed in the guidance law. The law is based on steering error, target angle-off and the relative velocities. It readily is automated either as an onboard aid to manned aircraft pilots or as a combat guidance law for unmanned vehicles.

A preference-ordered discrete-gaming approach to air-combat analysis

NASA Technical Reports Server (NTRS)

Kelley, H. J.; Lefton, L.

1978-01-01

An approach to one-on-one air-combat analysis is described which employs discrete gaming of a parameterized model featuring choice between several closed-loop control policies. A preference-ordering formulation due to Falco is applied to rational choice between outcomes: win, loss, mutual capture, purposeful disengagement, draw. Approximate optimization is provided by an active-cell scheme similar to Falco's obtained by a 'backing up' process similar to that of Kopp. The approach is designed primarily for short-duration duels between craft with large-envelope weaponry. Some illustrative computations are presented for an example modeled using constant-speed vehicles and very rough estimation of energy shifts.

Next generation cooled long range thermal sights with minimum size, weight, and power

Breiter, R.; Ihle, T.; Wendler, J.; Rühlich, I.; Ziegler, J.

2013-06-01

Situational awareness and precise targeting at day, night and severe weather conditions are key elements for mission success in asymmetric warfare. To support these capabilities for the dismounted soldier, AIM has developed a family of stand-alone thermal weapon sights based on high performance cooled IR-modules which are used e.g. in the infantryman of the future program of the German army (IdZ). The design driver for these sights is a long ID range <1500m for the NATO standard target to cover the operational range of a platoon with the engagement range of .50 cal rifles, 40mm AGLs or for reconnaissance tasks. The most recent sight WBZG has just entered into serial production for the IdZ enhanced system of the German army with additional capabilities like a wireless data link to the soldier backbone computer. Minimum size, weight and power (SWaP) are most critical requirements for the dismounted soldiers' equipment and sometimes push a decision towards uncooled equipment with marginal performance referring to the outstanding challenges in current asymmetric warfare, e.g. the capability to distinguish between combatants and non-combatants in adequate ranges. To provide the uncompromised e/o performance with SWaP parameters close to uncooled, AIM has developed a new thermal weapon sight based on high operating temperature (HOT) MCT MWIR FPAs together with a new low power single piston stirling cooler. In basic operation the sight is used as a clip-on in front of the rifle scope. An additional eyepiece for stand-alone targeting with e.g. AGLs or a biocular version for relaxed surveillance will be available. The paper will present details of the technologies applied for such long range cooled sights with size, weight and power close to uncooled.

The literature was searched to obtain publications regarding the historical development of Forward Surgical Teams and Combat Support Hospitals, as well as their surgical experiences in Iraq and Afghanistan. Relevant publications were reviewed in full and their results summarized. The doctrine behind the use of modern military surgical assets was not well developed at the start of the Iraq and Afghanistan conflicts. The Forward Surgical Team and Combat Support Hospital were used in practice only over the past decade. Because of the nature of these conflicts, both types of modern military surgical assets have not been used as intended and such units have operated in various roles, including combat support elements and civilian medical treatment facilities. As more research comes to light, a better appreciation for the future of American military medicine and surgery will develop. Published by Elsevier Inc.

Skillful performance in combat and racquet sports consists of proficient technique accompanied with efficient information-processing while engaged in moderate to high physical effort. This study examined information processing and decision-making using simple reaction time (SRT) and choice reaction time (CRT) paradigms in athletes of combat sports and racquet ball games while undergoing incrementally increasing physical effort ranging from low to high intensities. Forty national level experienced athletics in the sports of tennis, table tennis, fencing, and boxing were selected for this study. Each subject performed both simple (SRT) and four-choice reaction time (4-CRT) tasks at rest, and while pedaling on a cycle ergometer at 20%, 40%, 60%, and 80% of their own maximal aerobic power (Pmax). RM MANCOVA revealed significant sport-type by physical load interaction effect mainly on CRT. Least significant difference (LSD) posthoc contrasts indicated that fencers and tennis players process information faster with incrementally increasing workload, while different patterns were obtained for boxers and table-tennis players. The error rate remained stable for each sport type over all conditions. Between-sport differences in SRT and CRT among the athletes were also noted. Findings provide evidence that the 4-CRT is a task that more closely corresponds to the original task athletes are familiar with and utilize in their practices and competitions. However, additional tests that mimic the real world experiences of each sport must be developed and used to capture the nature of information processing and response-selection in specific sports.

Several aircraft airframe modeling approaches are currently being used in the DoD community for acquisition, threat evaluation, training, and other purposes. To date there has been no clear empirical study of the impact of airframe simulation fidelity on piloted real-time aircraft simulation study results, or when use of a particular level of fidelity is indicated. This paper documents a series of piloted simulation studies using three different levels of airframe model fidelity. This study was conducted using the NASA Langley Differential Maneuvering Simulator. Evaluations were conducted with three pilots for scenarios requiring extensive maneuvering of the airplanes during air combat. In many cases, a low-fidelity modified point-mass model may be sufficient to evaluate the combat effectiveness of the aircraft. However, in cases where high angle-of-attack flying qualities and aerodynamic performance are a factor or when precision tracking ability of the aircraft must be represented, use of high-fidelity models is indicated.

Posttraumatic stress disorder (PTSD) is a common psychiatric disorder among service members and veterans. The clinical course of PTSD varies between individuals, and patterns of symptom development have yet to be clearly delineated. Previous studies have been limited by convenience sampling, short follow-up periods, and the inability to account for combat-related trauma. To determine the trajectories of PTSD symptoms among deployed military personnel with and without combat exposure, we used data from a population-based representative sample of 8,178 US service members who participated in the Millennium Cohort Study from 2001 to 2011. Using latent growth mixture modeling, trajectories of PTSD symptoms were determined in the total sample, as well as in individuals with and without combat exposure, respectively. Overall, 4 trajectories of PTSD were characterized: resilient, pre-existing, new-onset, and moderate stable. Across all trajectories, combat-deployed service members diverged from non-combat-deployed service members, even after a single deployment. The former also generally had higher PTSD symptoms. Based on the models, nearly 90% of those without combat exposure remained resilient over the 10-year period, compared with 80% of those with combat exposure. Findings demonstrate that although the clinical course of PTSD symptoms shows heterogeneous patterns of development, combat exposure is uniformly associated with poor mental health.

Optimal functioning of the lower extremities under repeated movements on unstable surfaces is essential for military effectiveness. Intervention training to promote proprioceptive ability should be considered in order to limit the risk for musculoskeletal injuries. The aim of this study was to assess the effect of a proprioceptive intervention programme on static and dynamic postural balance among Israel Defense Forces combat soldiers. Twenty-seven male soldiers, aged 18-20 years, from a physical fitness instructor's course, were randomly divided into two groups matched by age and army unit. The intervention group (INT) underwent 4 weeks of proprioceptive exercises for 10 min daily; the control group underwent 4 weeks of upper body stretching exercises for 10 min daily. All participants were tested pre and postintervention for both static and dynamic postural balance. Significant interaction (condition*pre-post-test*group) was found for static postural balance, indicating that for the INT group, in condition 3 (on an unstable surface-BOSU), the post-test result was significantly better compared with the pretest result (p<0.05). Following intervention, the INT group showed significant correlations between static postural stability in condition 2 (eyes closed) and the dynamic postural stability (length of time walked on the beam following fatigue) ( r ranged from 0.647 to 0.822; p<0.05). The proprioceptive intervention programme for combat soldiers improved static postural balance on unstable surfaces, and improved the correlation between static postural balance in the eyes closed condition and dynamic postural balance following fatigue. Further longitudinal studies are needed to verify the relationship between proprioception programmes, additional weight bearing and the reduction of subsequent injuries in combat soldiers. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

As North Atlantic Treaty Organization (NATO) countries begin troop withdrawal from Afghanistan, military medicine needs programs for combat surgeons to retain the required knowledge and surgical skills. Each military branch runs programs at various Level I academic trauma centers to deliver predeployment training and provide a robust trauma experience for deploying surgeons. Outside of these successful programs, there is no system-wide mechanism for nondeploying military surgeons to care for a high volume of critically ill trauma patients on a regular basis in an educational environment that promotes continued professional development. We hypothesize that fully integrated military-civilian relationship regional Level I trauma centers provide a surgical experience more closely mirroring that seen in a Role III hospital than local Level II and Level III trauma center or medical treatment facilities. We characterized the Level I trauma center practice using the number of trauma resuscitations, operative trauma/acute care surgery procedures, number of work shifts, operative density (defined as the ratio of operative procedures/days worked), and frequency of educational conferences. The same parameters were collected from two NATO Role III hospitals in Afghanistan during the peak of Operation Enduring Freedom. Data for two civilian Level II trauma centers, two civilian Level III trauma centers, and a Continental United States Military Treatment Facility without trauma designation were collected. The number of trauma resuscitations, number of 24-hour shifts, operative density, and educational conferences are shown in the table for the Level I trauma center compared with the different institutions. Civilian center trauma resuscitations and operative density were highest at the Level I trauma center and were only slightly lower than what was seen in Afghanistan. Level II and III trauma centers had lower numbers for both. The Level I trauma center provided the most frequent educational opportunities. In a Level I academic trauma center integrated program, military and civilian surgeons have the same clinical and educational responsibilities: rounding and operating, managing critical care patients, covering trauma/acute care surgery call, and mentoring surgery residents in an integrated residency program. The Level I trauma center experience most closely mimics the combat surgeon experience seen at NATO Role III hospitals in Afghanistan compared with other civilian trauma centers. At high-volume Level I trauma centers, military surgeons will have a comprehensive trauma practice, including dedicated educational opportunities. We recommend integrated programs with Level I academic trauma centers as the primary mechanism for sustaining military combat surgical skills in the future.

Preliminary Evidence for the Impact of Combat Experiences on Gray Matter Volume of the Posterior Insula

2017-01-01

Background: Combat-exposed veteran populations are at an increased risk for developing cardiovascular disease. The anterior cingulate cortex (ACC) and insula have been implicated in both autonomic arousal to emotional stressors and homeostatic processes, which may contribute to cardiovascular dysfunction in combat veteran populations. The aim of the present study was to explore the intersecting relationships of combat experiences, rostral ACC and posterior insula volume, and cardiovascular health in a sample of combat veterans. Method: Twenty-four male combat veterans completed clinical assessment of combat experiences and posttraumatic stress symptoms. Subjects completed a magnetic resonance imaging scan and autosegmentation using FreeSurfer was used to estimate regional gray matter volume (controlling for total gray matter volume) of the rostral ACC and posterior insula. Flow-mediated dilation (FMD) was conducted to assess cardiovascular health. Theil-sen robust regressions and Welch's analysis of variance were used to examine relationships of combat experiences and PTSD symptomology with (1) FMD and (2) regional gray matter volume. Results: Increased combat experiences, deployment duration, and multiple deployments were related to smaller posterior insula volume. Combat experiences were marginally associated with poorer cardiovascular health. However, cardiovascular health was not related to rostral ACC or posterior insula volume. Conclusion: The present study provides initial evidence for the relationships of combat experiences, deployment duration, and multiple deployments with smaller posterior insula volume. Results may suggest that veterans with increased combat experiences may exhibit more dysfunction regulating the autonomic nervous system, a key function of the posterior insula. However, the relationship between combat and cardiovascular health was not mediated by regional brain volume. Future research is warranted to further clarify the cardiovascular or functional impact of smaller posterior insula volume in combat veterans. PMID:29312038

X-31 high angle of attack control system performance

NASA Technical Reports Server (NTRS)

Huber, Peter; Seamount, Patricia

1994-01-01

The design goals for the X-31 flight control system were: (1) level 1 handling qualities during post-stall maneuvering (30 to 70 degrees angle-of-attack); (2) thrust vectoring to enhance performance across the flight envelope; and (3) adequate pitch-down authority at high angle-of-attack. Additional performance goals are discussed. A description of the flight control system is presented, highlighting flight control system features in the pitch and roll axes and X-31 thrust vectoring characteristics. The high angle-of-attack envelope clearance approach will be described, including a brief explanation of analysis techniques and tools. Also, problems encountered during envelope expansion will be discussed. This presentation emphasizes control system solutions to problems encountered in envelope expansion. An essentially 'care free' envelope was cleared for the close-in-combat demonstrator phase. High angle-of-attack flying qualities maneuvers are currently being flown and evaluated. These results are compared with pilot opinions expressed during the close-in-combat program and with results obtained from the F-18 HARV for identical maneuvers. The status and preliminary results of these tests are discussed.

A technique for computer simulation of air combat is described. Volume 1 decribes the computer program and its development in general terms. Two versions of the program exist. Both incorporate a logic for selecting and executing air combat maneuvers with performance models of specific fighter aircraft. In the batch processing version the flight paths of two aircraft engaged in interactive aerial combat and controlled by the same logic are computed. The realtime version permits human pilots to fly air-to-air combat against the adaptive maneuvering logic (AML) in Langley Differential Maneuvering Simulator (DMS). Volume 2 consists of a detailed description of the computer programs.

Advanced technology development for remote triage applications in bleeding combat casualties.

Combat developers within the Army have envisioned development of a "wear-and-forget" physiological status monitor (PSM) that will enhance far forward capabilities for assessment of Warrior readiness for battle, as well as for remote triage, diagnosis and decision-making once Soldiers are injured. This paper will review recent work testing remote triage system prototypes in both the laboratory and during field exercises. Current PSM prototypes measure the electrocardiogram and respiration, but we have shown that information derived from these measurements alone will not be suited for specific, accurate triage of combat injuries. Because of this, we have suggested that development of a capability to provide a metric of circulating blood volume status is required for remote triage. Recently, volume status has been successfully modeled using low-level physiological signals obtained from wearable devices as input to machine-learning algorithms; these algorithms are already able to discriminate between a state of physical activity (common in combat) and that of central hypovolemia, and thus show promise for use in wearable remote triage devices.

Dutch approach to abating agricultural non-point pollution: farmers' behaviour and their motivation.

PubMed

Sloots, K; Spierenburg, P; van der Vlies, A W

2004-01-01

In The Netherlands, agricultural activities are one of the major diffuse sources of nutrients and crop protection chemicals. A national legal and regulatory framework has been developed to combat the environmental burden from the agricultural industry. This resulted in the implementation of a government decree (AMvB) in the year 2000. Under pressure from NGOs, the Hollandse Eilanden en Waarden Water Board worked on a regional regulation in advance of this national legislation. ZHEW followed an approach of research, communication and partnering prior to implementing the national decree. The most important result of the chosen approach is that compliance with one of the most important measures, the crop-free zone, is close to 100%. There has been little improvement in the amount of pesticides in the open waters. Both water board and farmers are positive about the approach followed. Monitoring and evaluation proved to be essential when communicating with the agricultural sector. The results of attempts to influence behaviour must be recorded in order maintain the motivation to change behaviour. Information on the effects of the approach adopted to combating diffuse agricultural sources is gathered from a number of sources.

Quality of life among Iranian refugees resettled in Sweden.

2004-04-01

The relationships between quality of life, psychopathological manifestations and coping related variables (coping resources, social support, sense of coherence) were examined among individuals who have perceived several severe traumata. One hundred Iranian refugees resettled in Sweden have been investigated by the Symptom Checklist (SCL-90-R), the Beck Depression Inventory (BDI), the Coping Resources Inventory (CRI), and the Interview Schedule for Social Interaction (ISSI), the Sense of Coherence Scale (SOC), and the WHOQoL-100 questionnaire in a cross-sectional study. Individuals, traumatized by combat experiences as a soldier during the war, with low BDI scores showed on average the significantly highest overall quality of life, the best physical health, the highest scores according to the sense of coherence most pronounced for "Meaningfulness," and the best availability of social integration compared to participants who did not had these experiences in combats and those with the experience but scored high in the BDI. Quality of life, coping resources, and social support were found closely related to psychopathological manifestations. Motivational orientations (highly developed Meaningfulness-SOC) and various coping competencies probably enable some traumatized individuals to resist against several traumata and to live in a good quality of life without psychopathological disturbances.

McCranie, E W; Hyer, L A

2000-07-01

Given important differences in the Korean conflict and World War II, samples of treatment-seeking combat veterans from these wars (30 Korea, 83 World War II) were compared on the prevalence and severity of posttraumatic stress disorder (PTSD). With age, ethnicity, and combat exposure taken into account, the Korean veterans reported significantly more severe symptoms on both interview and self-report PTSD measures. Group differences in the prevalence of current PTSD were in a similar direction but not significant. These results are generally consistent with other studies that have found Korean combat veterans to exhibit higher rates of psychosocial maladjustment than World War II combat veterans. Based on related research with Vietnam veterans, one direction for future investigation is to examine what role stressful postmilitary homecoming experiences may have played in influencing the development and course of combat-related PTSD in the aging cohort of "forgotten" Korean conflict veterans.

US combat operations in Iraq and Afghanistan have resulted in a greater proportion of service members with head and neck wounds caused by explosions compared with that of previous wars. Although penetrating traumatic brain injury (TBI) is frequently associated with these wounds, the epidemiology of penetrating TBI from these conflicts has not been well described. The Joint Theater Trauma Registry was queried for January 2003 through December 2010 to identify all patients with moderate-to-severe brain injury with a maximum Abbreviated Injury Scale (AIS) score of the head of 3 or greater and a diagnosis of penetrating or closed TBI in accordance with the Department of Defense Traumatic Brain Injury Surveillance definition. The epidemiology of these injuries was examined, including demographics, TBI severity, overall injury severity, and surgical interventions provided. A total of 1,255 TBI patients (774 penetrating, 481 closed) meeting criteria were identified. Penetrating brain injuries were more severe, more likely to be battle related, and less likely to be isolated injuries than a group of moderate-to-severe closed TBIs within the same range of anatomic injury severity. During the 5-year period of the Iraq war with the largest numbers of TBIs (2004-2008), the numbers of penetrating TBIs exceeded closed TBIs by a ratio of 2:1. During the 3-year period of the Afghanistan war with the greatest numbers of TBIs (2008-2010), the ratio of penetrating to closed TBIs was substantially lower, approximately 1.3:1. This study represents the first comprehensive report on the epidemiology of moderate-to-severe penetrating and closed TBIs resulting from the wars in Iraq and Afghanistan using Joint Theater Trauma Registry data. With the maturing theater of conflicts, penetrating TBIs were substantially less predominant compared with closed TBIs. While this finding may reflect changes in the use of protective measures and tactics or improvements in diagnosis of closed TBIs, additional research is needed to identify the reason for this shift and the subsequent effect on outcome after combat-related TBIs.

Introduction Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration. Project Design This was a quality assurance project that monitored training of combat medics to administer parenteral medications and to ensure patient safety. Combat medics were provided training that included direct supervision during medication administration. Once proficiency was demonstrated, combat medics would prepare the medications under direct supervision, followed by indirect supervision during administration. As part of the quality assurance and safety processes, combat medics were required to document all medication administrations, supervising provider, and unexpected adverse events. Additional quality assurance follow-up occurred via complete chart review by the project lead. Data During the project period, the combat medics administered the following medications: ketamine (n=13), morphine (n=8), ketorolac (n=7), fentanyl (n=5), ondansetron (n=4), and other (n=6). No adverse events or patient safety events were reported by the combat medics or discovered during the quality assurance process. In this limited case series, combat medics safely administered parenteral medications under indirect provider supervision. Future research is needed to further develop this training model for both the military and civilian setting. Schauer SG , Cunningham C W, Fisher AD , DeLorenzo RA .

Goza, Tracy H; Holden, Janice M; Kinsey, Lee

2014-10-01

The purpose of this study was to add to the professional literature regarding combat near-death experiences (cNDEs) and to help clinicians and experiencers (cNDErs) recognize this phenomenon as an experience that is not indicative of mental illness. cNDErs were military personnel whose NDEs occurred during active combat or sequelae. Sixty-eight self-reported survivors of combat-related close brushes with death completed an online survey that included the Near-Death Experience Scale(1) (NDE Scale), the Life-Changes Inventory-Revised(2), and a few open-ended questions. Respondents were 20 cNDErs-participants who scored at least 7 on the NDE Scale-and 48 non-NDErs. Compared to NDErs from two methodologically similar studies, cNDErs scored lower on Bonferroni corrected t-tests than NDErs on the NDE Scale overall(3) (p < 0.0003) and on Affective and Transcendental subscales; they scored higher on the Cognitive subscale(1) (p < 0.0007). In Life-Changes Inventory-Revised total change and six of seven value clusters, cNDErs, compared to non-NDErs, scored in the same direction as numerous other studies of NDE aftereffects, but none of the differences were statistically significant and all reflected small effect sizes except total change and changes in spirituality that reflected medium effect sizes--a finding that corresponded to analysis of narrative responses.

To examine the incidence and the etiology of corneal and corneoscleral injuries in the setting of combat ocular trauma, and to determine what effect these injuries have on overall visual impairment from combat ocular trauma. Retrospective, noncomparative, interventional case series, analyzing U.S. service members who were evacuated to the former Walter Reed Army Medical Center (WRAMC). Primary outcome measures were types of corneal injuries, length of follow-up at WRAMC, globe survival, and anatomical causes of blindness. Secondary outcome measures included surgical procedures performed, use of eye protection, source of injury, and visual outcomes. Between 2001 and 2011, there were 184 eyes of 134 patients with corneal or corneoscleral injuries. The average age was 26 years (range, 18-50); 99.3% were male, 31.9% had documented use of eye protection. The average follow-up was 428.2 days (3-2,421). There were 98 right-eye and 86 left-eye injuries. There were 169 open-globe and 15 closed-globe injuries with corneal lacerations occurring in 73 eyes with injuries to Zone I. Most injuries were attributable to an intraocular foreign body (IOFB; 48%), followed by penetrating (19.6%) and perforating (16.3%) injuries. The most common presenting visual acuity was hand motion/light perception (45.7%), yet, at the end of the study, visual acuity improved to 20/40 or better (40.8%). The majority of injuries in eyes with visual acuity worse than 20/200 involved the cornea and retina (58%). Injuries solely to the cornea accounted for only 19% of all injuries sustained. Ocular injuries in military combat have led to significant damage to ocular structures with a wide range of visual outcomes. The authors describe corneal and corneoscleral injuries in combat ocular trauma by classifying injuries by the anatomical site involved and identifying the main source of decreased visual acuity. In combat ocular trauma, corneal or corneoscleral injuries are not the sole etiology for poor vision. A cohesive approach among multiple ophthalmic subspecialties is needed when treating combat ocular trauma. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.

Nuclear quadrupole resonance detection of explosives: an overview

NASA Astrophysics Data System (ADS)

Miller, Joel B.

2011-06-01

Nuclear Quadrupole Resonance (NQR) is a spectroscopic technique closely related to Nuclear Magnetic Resonance (NMR) and Magnetic Resonance Imaging (MRI). These techniques, and NQR in particular, induce signals from the material being interrogated that are very specific to the chemical and physical structure of the material, but are relatively insensitive to the physical form of the material. NQR explosives detection exploits this specificity to detect explosive materials, in contrast to other well known techniques that are designed to detect explosive devices. The past two decades have seen a large research and development effort in NQR explosives detection in the United States aimed at transportation security and military applications. Here, I will briefly describe the physical basis for NQR before discussing NQR developments over the past decade, with particular emphasis on landmine detection and the use of NQR in combating IED's. Potential future directions for NQR research and development are discussed.

Nowadays desertification, as a global problem, affects many countries in the world, especially developing countries like Iran. With respect to increasing importance of desertification and its complexity, the necessity of attention to the optimal combating-desertification alternatives is essential. Selecting appropriate strategies according to all effective criteria to combat the desertification process can be useful in rehabilitating degraded lands and avoiding degradation in vulnerable fields. This study provides systematic and optimal strategies of combating desertification by use of a group decision-making model. To this end, the preferences of indexes were obtained through using the Delphi model, within the framework of multi-attribute decision making (MADM). Then, priorities of strategies were evaluated by using linear assignment (LA) method. According to the results, the strategies to prevent improper change of land use (A18), development and reclamation of plant cover (A23), and control overcharging of groundwater resources (A31) were identified as the most important strategies for combating desertification in this study area. Therefore, it is suggested that the aforementioned ranking results be considered in projects which control and reduce the effects of desertification and rehabilitate degraded lands.

Neural indicators of interpersonal anger as cause and consequence of combat training stress symptoms.

PubMed

Gilam, G; Lin, T; Fruchter, E; Hendler, T

2017-07-01

Angry outbursts are an important feature of various stress-related disorders, and commonly lead to aggression towards other people. Findings regarding interpersonal anger have linked the ventromedial prefrontal cortex (vmPFC) to anger regulation and the locus coeruleus (LC) to aggression. Both regions were previously associated with traumatic and chronic stress symptoms, yet it is unclear if their functionality represents a consequence of, or possibly also a cause for, stress symptoms. Here we investigated the relationship between the neural trajectory of these indicators of anger and the development and manifestation of stress symptoms. A total of 46 males (29 soldiers, 17 civilians) participated in a prospective functional magnetic resonance imaging experiment in which they played a modified interpersonal anger-provoking Ultimatum Game (UG) at two-points. Soldiers were tested at the beginning and end of combat training, while civilians were tested at the beginning and end of civil service. We assumed that combat training would induce chronic stress and result in increased stress symptoms. Soldiers showed an increase in stress symptoms following combat training while civilians showed no such change following civil service. All participants were angered by the modified UG irrespective of time point. Higher post-combat training stress symptoms were associated with lower pre-combat training vmPFC activation and with higher activation increase in the LC between pre- and post-combat training. Results suggest that during anger-provoking social interactions, flawed vmPFC functionality may serve as a causal risk factor for the development of stress symptoms, and heightened reactivity of the LC possibly reflects a consequence of stress-inducing combat training. These findings provide potential neural targets for therapeutic intervention and inoculation for stress-related psychopathological manifestations of anger.

Mitchell, Tarah; White, Edward D; Ritschel, Daniel

2014-06-01

The primary objective in this research involves determining the Air Force Physical Fitness Test's (AFPFT) predictability of combat fitness and whether measures within the AFPFT require modification to increase this predictability further. We recruited 60 female volunteers and compared their performance on the AFPFT to the Marine Combat Fitness Test, the proxy for combat fitness. We discovered little association between the two (R(2) of 0.35), however, this association significantly increased (adjusted R(2) of 0.56) when utilizing the raw scores of the AFPFT instead of using the gender/age scoring tables. Improving on these associations, we develop and propose a simple ordinary least squares regression model that minimally impacts the AFPFT testing routine. This two-event model for predicting combat fitness incorporates the 1.5-mile run along with the number of repetitions of a 30-lb dumbbell from chest height to overhead with arms extended during a 2-minute time span. These two events predicted combat fitness as assessed by the Marine Combat Fitness Test with an adjusted R(2) of 0.82. By adopting this model, we greatly improve the Air Force's ability to assess combat fitness for women. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

Combat injury patterns differ from civilian trauma in that the former are largely explosion-related, comprising multiple mechanistic and fragment injuries and high-kinetic-energy bullets. Further, unlike civilians, U.S. armed forces combatants are usually heavily protected with helmets and Kevlar body armor with ceramic plate inserts. Searchable databases providing actionable, statistically valid knowledge of body surface entry wounds and resulting organ injury severity are essential to understanding combat trauma. Two tools were developed to address these unique aspects of combat injury: (1) the Surface Wound Mapping (SWM) database and Surface Wound Analysis Tool (SWAT) software that were developed to generate 3D density maps of point-of-surface wound entry and resultant anatomic injury severity; and (2) the Abbreviated Injury Scale (AIS) 2005-Military that was developed by a panel of military trauma surgeons to account for multiple injury etiology from explosions and other high-kinetic- energy weapons. Combined data from the Joint Theater Trauma Registry, Navy/Marine Combat Trauma Registry, and the Armed Forces Medical Examiner System Mortality Trauma Registry were coded in AIS 2005-Military, entered into the SWM database, and analyzed for entrance site and wounding path. When data on 1,151 patients, who had a total of 3,500 surface wounds and 12,889 injuries, were entered into SWM, surface wounds averaged 3.0 per casualty and injuries averaged 11.2 per casualty. Of the 3,500 surface wounds, 2,496 (71%) were entrance wounds with 6,631 (51%) associated internal injuries, with 2.2 entrance wounds and 5.8 associated injuries per casualty (some details cannot be given because of operational security). Crude deaths rates were calculated using Maximum AIS-Military. These new tools have been successfully implemented to describe combat injury, mortality, and distribution of wounds and associated injuries. AIS 2005-Military is a more precise assignment of severity to military injuries. SWM has brought data from all three combat registries together into one analyzable database. SWM and SWAT allow visualization of wounds and associated injuries by region on a 3D model of the body.

Reports on penetrating ballistic head injuries in the literature are dominated by case studies of suicides; the penetrating ammunition usually being .22 rimfire or shotgun. The dominating cause of injuries in modern warfare is fragmentation and hence, this is the primary threat that military helmets protect the brain from. When helmets are perforated, this is usually by bullets. In combat, 20% of penetrating injuries occur to the head and its wounding accounts for 50% of combat deaths. A number of head simulants are described in the academic literature, in ballistic test methods for helmets (including measurement of behind helmet blunt trauma, BHBT) and in the 'open' and 'closed' government literature of several nations. The majority of these models are not anatomically correct and are not assessed with high-velocity rifle ammunition. In this article, an anatomically correct 'skull' (manufactured from polyurethane) and 'brain' (manufactured from 10%, by mass, gelatine) model for use in military wound ballistic studies is described. Filling the cranium completely with gelatine resulted in a similar 'skull' fracture pattern as an anatomically correct 'brain' combined with a representation of cerebrospinal fluid. In particular, posterior cranial fossa and occipital fractures and brain ejection were observed. This pattern of injury compared favourably to reported case studies of actual incidents in the literature.

As the only burn center in the Department of Defense, the U.S. Army Institute of Surgical Research is the primary location for care of service members with burn injuries. The combat operations in Iraq and Afghanistan during the past decade have caused an increase in burn patients. As a result of this increased need, advancements in care were developed. The speed and precision of transporting patients from the battlefield to the burn center has improved over previous conflicts. Technological advancements to support treating complications of burn wound healing were leveraged and are now integrated into daily practice. Clinical decision support systems were developed and deployed at the burn center as well as to combat support hospitals in combat zones. Technology advancements in rehabilitation have allowed more service members to return to active duty or live productive civilian lives. All of these advancements were developed in a patient-centered, interdisciplinary environment where the nurses are integrated throughout the research process and clinical practice with the end goal of healing combat burns in mind.

We build a complex networks model of combat System-of-Systems (SoS) based on empirical data from a real war-game, this model is a combination of command & control (C2) subnetwork, sensors subnetwork, influencers subnetwork and logistical support subnetwork, each subnetwork has idiographic components and statistical characteristics. The C2 subnetwork is the core of whole combat SoS, it has a hierarchical structure with no modularity, of which robustness is strong enough to maintain normal operation after any two nodes is destroyed; the sensors subnetwork and influencers subnetwork are like sense organ and limbs of whole combat SoS, they are both flat modular networks of which degree distribution obey GEV distribution and power-law distribution respectively. The communication network is the combination of all subnetworks, it is an assortative Small-World network with core-periphery structure, the Intelligence & Communication Stations/Command Center integrated with C2 nodes in the first three level act as the hub nodes in communication network, and all the fourth-level C2 nodes, sensors, influencers and logistical support nodes have communication capability, they act as the periphery nodes in communication network, its degree distribution obeys exponential distribution in the beginning, Gaussian distribution in the middle, and power-law distribution in the end, and its path length obeys GEV distribution. The betweenness centrality distribution, closeness centrality distribution and eigenvector centrality are also been analyzed to measure the vulnerability of nodes.

Combat Exposure in Early Adulthood Interacts with Recent Stressors to Predict PTSD in Aging Male Veterans.

PubMed

Sachs-Ericsson, Natalie; Joiner, Thomas E; Cougle, Jesse R; Stanley, Ian H; Sheffler, Julia L

2016-02-01

Combat is a risk factor for posttraumatic stress disorder (PTSD); however, less is known about how exposure to combat in early adulthood may contribute to the development of PTSD as the individual ages. Prior exposure to trauma may "sensitize" people to respond more intensely to subsequent stressors. Further, aging initiates new challenges that may undermine previous coping strategies. Over the life course combat veterans may be more reactive to new stressors and thus be more vulnerable to PTSD. This study draws on the two waves of the National Comorbidity Survey (NCS-1) and NCS-2 (10-year follow-up). Participants were male (noncombat N = 620 and combat N = 107) and 50-65 years of age at Wave-2. At baseline, participants were assessed for exposure to wartime combat, number of Diagnostic and Statistical Manual of Mental Disorders (DSM) diagnoses in the past year, and life-time PTSD. At follow-up, PTSD occurring between waves was determined. A measure of recent life stressors was also obtained. Using logistic regression analyses, combat predicted PTSD at follow-up (controlling for baseline demographics, number of DSM diagnoses in the past year, life-time PTSD). Recent life stressors were also associated with PTSD. Importantly, the effect of combat on PTSD was significant at high levels, but not low levels, of recent life stress. Veterans who have experienced combat may be more reactive to new stressors, and in turn be more vulnerable to PTSD. Combat veterans should be regularly assessed for current stressors and PTSD. © The Author 2015. Published by Oxford University Press on behalf of The Gerontological Society of America.

Research suggests that the nature of combat may affect later development of posttraumatic stress disorder (PTSD) in combat veterans. Studies comparing rates of PTSD across different conflicts indicate that the use of asymmetric or guerilla-style tactics by enemy fighters may result in higher rates of PTSD among U.S. military personnel than the use of symmetric tactics, which mirror tactics used by U.S. forces. Investigations of the association between enemy combat tactics and PTSD across conflicts were limited because of cohort effects and a focus on male veterans. The current study examined rates of PTSD diagnosis in a sample of male and female veterans deployed to Operation Iraqi Freedom (OIF), a conflict with 3 distinct phases marked by varying enemy tactics. Participants were 738 veterans enrolled in Project VALOR (Veterans' After-Discharge Longitudinal Registry) who deployed once to OIF. Participants completed a clinician interview as well as self-report measures. Male veterans deployed during the OIF phase marked by asymmetric tactics were more than twice as likely to be diagnosed with PTSD as those deployed during the other 2 phases, even after controlling for extent of combat exposure, demographic characteristics, and other deployment-related risk factors for PTSD. Differing rates of PTSD across the 3 OIF phases were not observed among female participants. The nature of combat (specifically, asymmetric enemy tactics) may be a risk factor for the development of PTSD among males. Factors other than enemy tactics may be more important to the development of PTSD among females. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Although women in the military are exposed to combat and its aftermath, little is known about whether combat as well as pre-deployment risk/protective factors differentially predict post-deployment PTSD symptoms among women compared to men. The current study assesses the influence of combat-related stressors and pre-deployment risk/protective factors on women's risk of developing PTSD symptoms following deployment relative to men's risk. Participants were 801 US National Guard Soldiers (712 men, 89 women) deployed to Iraq or Afghanistan who completed measures of potential risk/protective factors and PTSD symptoms one month before deployment (Time 1) and measures of deployment-related stressors and PTSD symptoms about 2-3 months after returning from deployment (Time 2). Men reported greater exposure to combat situations than women, while women reported greater sexual stressors during deployment than men. Exposure to the aftermath of combat (e.g., witnessing injured/dying people) did not differ by gender. At Time 2, women reported more severe PTSD symptoms and higher rates of probable PTSD than did men. Gender remained a predictor of higher PTSD symptoms after accounting for pre-deployment symptoms, prior interpersonal victimization, and combat related stressors. Gender moderated the association between several risk factors (combat-related stressors, prior interpersonal victimization, lack of unit support and pre-deployment concerns about life/family disruptions) and post-deployment PTSD symptoms. Elevated PTSD symptoms among female service members were not explained simply by gender differences in pre-deployment or deployment-related risk factors. Combat related stressors, prior interpersonal victimization, and pre-deployment concerns about life and family disruptions during deployment were differentially associated with greater post-deployment PTSD symptoms for women than men.

Antimicrobial resistance (AMR) is increasingly perceived as a global health problem. To tackle AMR effectively, a multisectoral one health approach is needed. We present some of the initiatives and activities at the national and global level that target the AMR challenge. The Global Action Plan on AMR, which has been developed by the World Health Organization (WHO), in close collaboration with the Food and Agriculture Organization of the United Nations (FAO) and the World Organisation for Animal Health (OIE) is considered a blueprint to combat AMR. Member states endorsed the action plan during the World Health Assembly 2015 and committed themselves to develop national action plans on AMR. The German Antibiotic Resistance Strategy (DART 2020) is based on the main objectives of the global action plan and was revised and published in 2015. Several examples of the implementation of DART 2020 are outlined here.

Importance Combat places soldiers at risk for post-traumatic stress disorder (PTSD). The excessive rates of PTSD and other adjustment disorders in soldiers returning home make it imperative to identify risk and resilience factors that could be targeted by novel therapeutic treatments. Objective To investigate the interplay among attention to threat, combat exposure, and other risk factors for PTSD symptoms in soldiers deployed to combat. Design and Setting Longitudinal prospective study of Israeli Defense Force infantry soldiers carried out in 2008 through 2010. Repeated measurements during a 1-year period included baseline and predeployment data collected in training camps and deployment data collected in the combat theater. Participants Infantry soldiers (1085 men; mean age,18.8 years). Main Outcome Measures Postcombat PTSD symptoms. Results Soldiers developed threat vigilance during combat deployment, particularly when they were exposed to high-intensity combat, as indicated by faster response times to targets appearing at the location of threat relative to neutral stimuli (P < .001). Threat-related attention bias also interacted with combat exposure to predict risk for PTSD (P <.05). Bias toward threat at recruitment (P <.001) and bias away from threat just before deployment (P < .05) predicted postcombat PTSD symptoms. Moreover, these threat-related attention associations with PTSD were moderated by genetic and environmental factors, including serotonin transporter (5-HTTLPR) genotype. Conclusions and Relevance Combat exposure interacts with threat-related attention to place soldiers at risk for PTSD, and interactions with other risk factors account for considerable variance in PTSD vulnerability. Understanding these associations informs research on novel attention bias modification techniques and prevention of PTSD. PMID:23407816

: Strategies currently used to prevent morbidity and mortality associated with combat-related injuries include better training of frontline medical personnel, improved personal protective equipment, and deployment of fast-forward surgical assets with state-of-the-art equipment. These strategies allow patients to survive near-catastrophic injuries, placing a greater emphasis on the medical infrastructure to mitigate short- and long-term complications associated with these injuries. : Wounds have certain characteristics that promote the development of infections: the presence of devitalized tissue, foreign bodies, clots, fluid collections, and contamination of wounds with bacteria from the casualty's skin, the environment, and the hospital. All of these factors culminate in placing the casualty at risk of developing an infection. : This article reviews the lessons learned from combat-related wound infections throughout history and in the current conflicts in Iraq and Afghanistan. Many of the management strategies used to prevent infections of combat-related injuries are applicable to the management of civilian trauma, whether associated with small arms fire or related to natural disasters such as earthquakes or tornadoes.

The Combat Wound Initiative (CWI) program is a collaborative, multidisciplinary, and interservice public-private partnership that provides personalized, state-of-the-art, and complex wound care via targeted clinical and translational research. The CWI uses a bench-to-bedside approach to translational research, including the rapid development of a human extracorporeal shock wave therapy (ESWT) study in complex wounds after establishing the potential efficacy, biologic mechanisms, and safety of this treatment modality in a murine model. Additional clinical trials include the prospective use of clinical data, serum and wound biomarkers, and wound gene expression profiles to predict wound healing/failure and additional clinical patient outcomes following combat-related trauma. These clinical research data are analyzed using machine-based learning algorithms to develop predictive treatment models to guide clinical decision-making. Future CWI directions include additional clinical trials and study centers and the refinement and deployment of our genetically driven, personalized medicine initiative to provide patient-specific care across multiple medical disciplines, with an emphasis on combat casualty care.

Reconciling reintegration: the complexity of economic and social reintegration of ex-combatants in Burundi.

PubMed

Willems, Rens; van Leeuwen, Mathijs

2015-04-01

The extent to which disarmament, demobilisation and reintegration (DDR) programmes initiated by state or multilateral agencies can realise the reintegration of ex-combatants remains debated. While some consider that DDR should have the ambition to result in long-term reintegration, others argue that DDR should focus on short-term goals. This paper explores experiences with the reintegration of ex-combatants in Burundi. It shows the interconnectedness of economic and social reintegration processes, and demonstrates that the reintegration of ex-combatants cannot be seen in isolation from the wider recovery and development context in which DDR is taking place. Moreover, the case demonstrates that reconciliation and social reintegration are deeply interconnected, to the extent that social reintegration may fail if reconciliation is not taken into account. Rather than a debate between long- and short-term goals, the focus should therefore be on increasing the understanding of reintegration processes and finding ways in which programmes can contribute to those. © 2015 The Author(s).

Background Research suggests that personality traits have both direct and indirect effects on the development of psychological symptoms, with indirect effects mediated by stressful or traumatic events. This study models the direct influence of personality traits on residualized changes in internalizing and externalizing symptoms following a stressful and potentially traumatic deployment, as well as the indirect influence of personality on symptom levels mediated by combat exposure. Method We utilized structural equation modeling with a longitudinal prospective study of 522 US National Guard soldiers deployed to Iraq. Analyses were based on self-report measures of personality, combat exposure, and internalizing and externalizing symptoms. Results Both pre-deployment Disconstraint and externalizing symptoms predicted combat exposure, which in turn predicted internalizing and externalizing symptoms. There was a significant indirect effect for pre-deployment externalizing symptoms on post-deployment externalizing via combat exposure (p < .01). Negative Emotionality and pre-deployment internalizing symptoms directly predicted post-deployment internalizing symptoms, but both were unrelated to combat exposure. No direct effects of personality on residualized changes in externalizing symptoms were found. Conclusions Baseline symptom dimensions had significant direct and indirect effects on post-deployment symptoms. Controlling for both pre-exposure personality and symptoms, combat experiences remained positively related to both internalizing and externalizing symptoms. Implications for diagnostic classification are discussed. PMID:26347314

Weight Loss Strategies in Combat Sports and Concerning Habits in Mixed Martial Arts.

PubMed

Barley, Oliver R; Chapman, Dale W; Abbiss, Chris R

2017-12-28

Combat sports are typically divided into weight classes and body mass manipulation to reach a weight class is commonplace. Previous research suggests that mixed martial arts (MMA) weight loss practices may be more extreme than other combat sports. We sought to investigate the magnitude of weight lost and prevalence of weight loss strategies in different combat sports. Competitors (n=637) from Brazilian jiu jitsu (BJJ), boxing, judo, MMA, muay Thai/kickboxing (MT/K), taekwondo (TKD) and wrestling completed an online questionnaire seeking information regarding their weight loss practices. Body mass manipulation was commonly undertaken by all combat sports athletes, with a particularly high incidence of gradual dieting, increased exercise and fluid restriction. Skipping meals was higher in TKD and wrestling (84%) compared with the other combat sports (~58%), whilst training in heated rooms and forced oral fluid loss (spitting) was higher in wrestling (83% and 47%, respectively) compared with other combat sports (~45% and ~19%, respectively). MMA athletes reported the highest usage of sauna (76%) and water loading (67%) whilst also reporting the second highest use of training in rubber/plastic suits (63%). Body mass manipulation was present in all combat sports with the prevalence and magnitude of acute weight loss greater in MMA. The incidence of and practices reported will assist support staff to be fully aware of the variety of methods these athletes and coaches may use to achieve weight loss. Additionally, the results could aid regulatory bodies in the further development of policies on weight cutting.

Air Superiority Fighter is considered to be an effective dogfighter which is stealthy & highly maneuverable to surprise enemy along with improve survivability against the missile fire. This new generation fighter aircraft requires fantastic aerodynamics design, low wing loading (W/S), high thrust to weight ratio (T/W) with super cruise ability. Conceptual design is the first step to design an aircraft. In this paper conceptual design of an Air Superiority Fighter Aircraft is proposed to carry 1 crew member (pilot) that can fly at maximum Mach No of 2.3 covering a range of 1500 km with maximum ceiling of 61,000 ft. Payload capacity of this proposed aircraft is 6000 lb that covers two advanced missiles & one advanced gun. The Air Superiority Fighter Aircraft was designed to undertake all the following missions like: combat air petrol, air to air combat, maritime attack, close air support, suppression, destruction of enemy air defense and reconnaissance.

Neck muscle activation and head postures in common high performance aerial combat maneuvers.

PubMed

Netto, Kevin J; Burnett, Angus F

2006-10-01

Neck injuries are common in high performance combat pilots and have been attributed to high gravitational forces and the non-neutral head postures adopted during aerial combat maneuvers. There is still little known about the pathomechanics of these injuries. Six Royal Australian Air Force Hawk pilots flew a sortie that included combinations of three +Gz levels (1, 3, and 5) and four head postures (Neutral, Turn, Extension, and Check-6). Surface electromyography from neck and shoulder muscles was recorded in flight. Three-dimensional measures of head postures adopted in flight were estimated postflight with respect to end-range of the cervical spine using an electromagnetic tracking device. Mean muscle activation increased significantly with both increasing +Gz and non-neutral head postures. Check-6 at +5 Gz (mean activation of all muscles = 51% MVIC) elicited significantly greater muscle activation in most muscles when compared with Neutral, Extension, and Turn head postures. High levels of muscle co-contraction were evident in high acceleration and non-neutral head postures. Head kinematics showed Check-6 was closest to end-range in any movement plane (86% ROM in rotation) and produced the greatest magnitude of rotation in other planes. Turn and Extension showed a large magnitude of rotation with reference to end-range in the primary plane of motion but displayed smaller rotations in other planes. High levels of neck muscle activation and co-contraction due to high +Gz and head postures close to end range were evident in this study, suggesting the major influence of these factors on the pathomechanics of neck injuries in high performance combat pilots.

Physiological employment standards IV: integration of women in combat units physiological and medical considerations.

PubMed

Epstein, Yoram; Yanovich, Ran; Moran, Daniel S; Heled, Yuval

2013-11-01

Anthropometric and physiological factors place the average female soldier at a disadvantage relative to male soldiers in most aspects of physical performance. Aerobic and anaerobic fitness levels are lower in women than in men. Thus, women have a lower overall work capacity and must therefore exert themselves more than men to achieve the same output. The lower weight and fat-free mass and the higher body fat of women are associated with lower muscle strength and endurance, placing them at disadvantage compared with men in carrying out military tasks such as lifting and carrying weights or marching with a load. Working at a higher percentage of their maximal capacity to achieve the same performance levels as men, women tire earlier and are at increased risk of overuse injuries. Their smaller size, different bone geometry and lower bone strength also predispose women to a higher incidence of stress fractures. Although training in gender-integrated groups narrows the gaps in fitness, significant differences between the genders after basic training still remain. Nevertheless, integration of women into military combat professions is feasible in many cases. Some 'close combat roles' will still be an exception, mainly because of the extreme physical demands that are required in those units that are beyond the physiological adaptability capacities of an average female. There is no direct evidence that women have a negative impact on combat effectiveness. Once the gender differences are acknowledged and operational doctrines adjusted accordingly, female soldiers in mixed-gender units can meet the physical standards for the assigned missions.

While the list presented here is by no means a comprehensive list of all of the research areas of interest in battlefield trauma care, much less a list of research needs across the entire continuum of combat casualty care, it does provide the collective judgment of the CoTCCC about the highest priorities for RDT&E that relate to battlefield trauma care. Two additional observations should be made regarding that point: (1) As the landmark Eastridge et al. 2012 study convincingly documented, most combat fatalities occur in the prehospital phase of care, so research efforts that enable Combat medics, corpsmen, and PJs to care for their casualties more effectively will convey the highest probability of further reducing the case fatality rate and preventable deaths among US Combat casualties; and (2) inasmuch as the mission of the CoTCCC is to update the TCCC Guidelines as needed, this group has excellent visibility of the most important current research questions in battlefield trauma care.

Performance on movement tests helps to predict injury risk in a variety of physically active populations. Understanding baseline measures for normal is an important first step. Determine differences in physical performance assessments and describe normative values for these tests based on military unit type. Assessment of power, balance, mobility, motor control, and performance on the Army Physical Fitness Test were assessed in a cohort of 1,466 soldiers. Analysis of variance was performed to compare the results based on military unit type (Rangers, Combat, Combat Service, and Combat Service Support) and analysis of covariance was performed to determine the influence of age and gender. Rangers performed the best on all performance and fitness measures (p < 0.05). Combat soldiers performed better than Combat Service and Service Support soldiers on several physical performance tests and the Army Physical Fitness Test (p < 0.05). Performance in Combat Service and Service Support soldiers was equivalent on most measures (p < 0.05). Functional performance and level of fitness varied significantly by military unit type. Understanding these differences will provide a foundation for future injury prediction and prevention strategies. Reprint & Copyright © 2016 Association of Military Surgeons of the U.S.

2008-03-01

Orthopedic injuries suffered by casualties during combat constitute approximately 65% of the total percentage of injuries and are evenly distributed between upper and lower extremities. The high-energy explosive injuries, environmental contamination, varying evacuation procedures, and progressive levels of medical care make managing combat-related injuries challenging. The goals of orthopedic injury management are to prevent infection, promote fracture healing, and restore function. It appears that 2% to 15% of combat-related extremity injuries develop osteomyelitis, although lower extremity injuries are at higher risk of infections than upper extremity. Management strategies of combat-related injuries primarily focus on early surgical debridement and stabilization, antibiotic administration, and delayed primary closure. Herein, we provide evidence-based recommendations from military and civilian data to the management of combat-related injuries of the extremity. Areas of emphasis include the utility of bacterial cultures, antimicrobial therapy, irrigation fluids and techniques, timing of surgical care, fixation, antibiotic impregnated beads, wound closure, and wound coverage with negative pressure wound therapy. Most of the recommendations are not supported by randomized controlled trials or adequate cohorts studies in a military population and further efforts are needed to answer best treatment strategies.

Combat-related eye injuries entail enormous financial, social and psychological cost. Military Combat Eye Protection (MCEP) decreases both the incidence and severity of eye injuries. Experts have recognised the need for MCEP for Indian soldiers. We aim to review the combat-related eye injuries and combat eye protection among the Indian soldiers. Global practices of MCEP are also reviewed. We also aim to offer our recommendations for Indian soldiers. We carried out Medline search for combat-related eye injuries and MCEP and separately searched for eye injuries among Indian soldiers during war and other operations. We present the findings as results. Recommendations are based on the opinions of the experts. Combat-related eye injuries increased from 3% of injured in the 1965 Indo-Pakistan War to 4.8% in 1971 war. During peace-keeping operations in Sri Lanka (1987-89) eye injuries increased to 10.5% of the injured. Statistics on eye injuries during counterinsurgency operations are not available. MCEP have shown reduction in eye injuries, and thus MCEP forms a part of personal equipment of the soldiers in developed countries. Indian soldiers do not have provision of MCEP. Combat-related eye injuries among Indian Army soldiers have been increasing. Data on eye injuries during counterinsurgency operations are not available. Indian soldiers do not have provision of MCEP. Provision of MCEP is therefore desirable. Awareness program among the commanders and the soldiers shall result in attitudinal changes and increased compliance.

2018-04-01

Understanding the complex interrelationships between combat injuries, physical health, and mental health symptoms is critical to addressing the healthcare needs of wounded military personnel and veterans. The relationship between injury characteristics, pain, posttraumatic stress disorder (PTSD), and depression among combat-injured military personnel is unique to modern conflicts and understudied in the nursing literature. This integrative review synthesizes clinical presentations and relationships of combat injury, PTSD, depression, and pain in Operation Enduring Freedom (OEF) and Operation Iraqi Freedom (OIF) United States military service members and veterans. A literature search was conducted using relative key terms across databases to identify peer-reviewed publications between 2001 and 2016 that examined health outcomes of combat-injured persons in OEF and OIF. The quality of evidence was evaluated and results synthesized to examine the association of combat injury as a risk factor for PTSD, the relationship of PTSD and depression pre- and postinjury, and pain management throughout care. Twenty-two articles were included in this review. Greater injury and pain severity poses risks for developing PTSD following combat injury, while early symptom management lessens risks for PTSD. Depression appears to be both a contributing risk factor to postinjury PTSD, as well as a comorbidity. Findings demonstrate a compelling need for improvements in standardized assessment of pain and mental health symptoms across transitions in care. This integrative review informs nurse researchers and providers of the clinical characteristics of pain, PTSD, and depression following combat injury and offers implications for future research promoting optimal surveillance of symptoms. © 2018 Sigma Theta Tau International.

External fixation is the recommended stabilization method for both open and closed fractures of long bones in forward surgical hospitals. Specific combat surgical tactics are best performed using dedicated external fixators. The Percy Fx (Biomet) fixator was developed for this reason by the French Army Medical Service, and has been used in various theatres of operations for more than ten years. The tactics of Percy Fx (Biomet) fixator use were analysed in two different situations: for the treatment of French soldiers wounded on several battlefields and then evacuated to France and for the management of local nationals in forward medical treatment facilities in Afghanistan and Chad. Overall 48 externals fixators were implanted on 37 French casualties; 28 frames were temporary and converted to definitive rigid frames or internal fixation after medical evacuation. The 77 Afghan patients totalled 85 external fixators, including 13 temporary frames applied in Forward Surgical Teams (FSTs) prior to their arrival at the Kabul combat support hospital. All of the 47 Chadian patients were treated in a FST with primary definitive frames because of delayed surgical management and absence of higher level of care in Chad. Temporary frames were mostly used for French soldiers to facilitate strategic air medical evacuation following trauma damage control orthopaedic principles. Definitive rigid frames permitted achieving treatment of all types of war extremity injuries, even in poor conditions.

There is a well documented need to replenish the antibiotic pipeline with new agents to combat the rise of drug resistant bacteria. One strategy to combat resistance is to discover new chemical classes immune to current resistance mechanisms that inhibit essential metabolic enzymes. Many of the obvious drug targets that have no homologous isozyme in the human host have now been investigated. Bacterial drug targets that have a closely related human homologue represent a new frontier in antibiotic discovery. However, to avoid potential toxicity to the host, these inhibitors must have very high selectivity for the bacterial enzyme over the human homolog. We have demonstrated that the essential enzyme biotin protein ligase (BPL) from the clinically important pathogen Staphylococcus aureus could be selectively inhibited. Linking biotin to adenosine via a 1,2,3 triazole yielded the first BPL inhibitor selective for S. aureus BPL over the human equivalent. The synthesis of new biotin 1,2,3-triazole analogues using click chemistry yielded our most potent structure (Ki 90 nm) with a >1100-fold selectivity for the S. aureus BPL over the human homologue. X-ray crystallography confirmed the mechanism of inhibitor binding. Importantly, the inhibitor showed cytotoxicity against S. aureus but not cultured mammalian cells. The biotin 1,2,3-triazole provides a novel pharmacophore for future medicinal chemistry programs to develop this new antibiotic class. PMID:22437830

1994-01-01

Relatively little is known about posttraumatic stress disorder (PTSD) in World War II (WWII) veterans, despite the significant number of studies on this problem in Vietnam veterans. The authors document the prevalence of PTSD and other psychiatric disorders and investigate the etiological correlates of the syndrome in elderly, institutionalized WWII veterans. Sixty-two cognitively intact subjects (mean age 74.2 years), residents in a veterans' long-term care facility, were assessed for past and present psychopathology. A second investigator, blind to patients' psychiatric status, determined the degree of combat exposure and administered a checklist of pre-war and wartime variables. The lifetime prevalence of PTSD was 23%. Of those veterans with PTSD, 57% experienced chronic symptoms. The lifetime prevalence of other diagnoses was also high, including 3 7% for major depression and 53% for alcohol abuse. There was a strong correlation between the severity of the combat stressor and the development of PTSD. Significant correlations between PTSD and some pre-war variables were also found: more family histories of alcohol abuse, more deaths of close family members in early life, and less likelihood of having held a job for more than 1 year prior to the war. PTSD in elderly, institutionalized WWII veterans is a common, serious problem that is often unrecognized. Copyright © 1994 American Association for Geriatric Psychiatry. Published by Elsevier Inc.

Post-traumatic stress disorder (PTSD) is a complex mental disorder with psychological and emotional components, caused by exposure to single or repeated extreme traumatic events found in war, terrorist attacks, natural or man-caused disasters, and by violent personal assaults and accidents. Mild traumatic brain injury (TBI) occurs when the brain is violently rocked back and forth within the skull following a blow to the head or neck as in contact sports, or when in close proximity to a blast pressure wave following detonation of explosives in the battlefield. Penetrating TBI occurs when an object penetrates the skull and damages the brain, and is caused by vehicle crashes, gunshot wound to the head, and exposure to solid fragments in the proximity of explosions, and other combat-related head injuries. Despite clinical studies and improved understanding of the mechanisms of cellular damage, prevention and treatment strategies for patients with PTSD and TBI remain unsatisfactory. To develop an improved plan for treating and impeding progression of PTSD and TBI, it is important to identify underlying biochemical changes that may play key role in the initiation and progression of these disorders. This review identifies three common biochemical events, namely oxidative stress, chronic inflammation and excitotoxicity that participate in the initiation and progression of these conditions. While these features are separately discussed, in many instances, they overlap. This review also addresses the goal of developing novel treatments and drug regimens, aimed at combating this triad of events common to, and underlying, injury to the brain.

1989-05-01

Ongoing research and evaluation projects sponsored by the Army Medical Research and Development Command are leading towards filmless radiography in the combat casualty care system of the 1990s. With the elimination of film, the question arises as to the most appropriate medium for archiving and transporting x-ray images and related patient data with the wounded between facilities. This paper considers the pros and cons of the various candidate media in relation to their specifications, availability, and appropriateness under simulated combat casualty care conditions.

Posttraumatic stress disorder (PTSD) worsens prognosis following mild traumatic brain injury (mTBI). Combat personnel with histories of mTBI exhibit abnormal activation of distributed brain networks-including emotion processing and default mode networks. How developing PTSD further affects these abnormalities has not been directly examined. We recorded electroencephalography in combat veterans with histories of mTBI, but without active PTSD (mTBI only, n=16) and combat veterans who developed PTSD after mTBI (mTBI+PTSD, n=16)-during the Reading the Mind in the Eyes Test (RMET), a validated test of empathy requiring emotional appraisal of facial features. Task-related event related potentials (ERPs) were identified, decomposed using independent component analysis (ICA) and localized anatomically using dipole modeling. We observed larger emotional face processing ERPs in veterans with mTBI+PTSD, including greater N300 negativity. Furthermore, greater N300 negativity correlated with greater PTSD severity, especially avoidance/numbing and hyperarousal symptom clusters. This correlation was dependent on contributions from the precuneus and posterior cingulate cortex (PCC). Our results support a model where, in combat veterans with histories of mTBI, larger ERPs from over-active posterior-medial cortical areas may be specific to PTSD, and is likely related to negative self-referential activity. © 2013 Published by Elsevier B.V.

Martial arts as sport and therapy.

Burke, D T; Al-Adawi, S; Lee, Y T; Audette, J

2007-03-01

The term Martial Arts is often used as general phrase to describe many of the combat arts, which have developed in eastern cultures over the past millennium. This paper reviews the Martial Arts from the original context of a trio of life skills. This trio includes the healing arts such as acupuncture, the self-exploration arts such as yoga, and the vital life skills such as meditation. As Martial Arts suggests the waging of combat, the origins of the most common combat arts are reviewed, with an overview of the difference between the hard and the soft styles. The arts developed not only in the eastern, but also in all parts of the world, with references of these types of combats arts in the writings of the ancient Egyptians and Greeks. In modern times, the combat arts are performed for both exercise and sport. A review of the injuries that occur, and the health benefits that might be expected are discussed. A review of the medical literature that demonstrates some of these health benefits is included, with Tai Chi Chuan as the most studied of these. The health benefits discussed include strengthen and self-efficacy of the elderly, reduced falls, increased exercise capacity, and benefits to the immune system and autonomic nervous system. The paper emphasized the breadth of the Martial Arts and the import of these to the sports and health community.

The effect of military deployments to combat environments on disordered eating and weight changes is unknown. Using longitudinal data from Millennium Cohort Study participants who completed baseline (2001-2003) and follow-up (2004-2006) questionnaires (n=48,378), the authors investigated new-onset disordered eating and weight changes in a large military cohort. Multivariable logistic regression was used to compare these outcomes among those who deployed and reported combat exposures, those who deployed but did not report combat exposures, and those who did not deploy in support of the wars in Iraq and Afghanistan. Deployment was not significantly associated with new-onset disordered eating in women or men, after adjustment for baseline demographic, military, and behavioral characteristics. However, in subgroup comparison analyses of deployers, deployed women reporting combat exposures were 1.78 times more likely to report new-onset disordered eating (95% confidence interval: 1.02, 3.11) and 2.35 times more likely to lose 10% or more of their body weight compared with women who deployed but did not report combat exposures (95% confidence interval: 1.17, 4.70). Despite no significant overall association between deployment and disordered eating and weight changes, deployed women reporting combat exposures represent a subgroup at higher risk for developing eating problems and weight loss.

PTSD in active combat soldiers: to treat or not to treat.

PubMed

Wangelin, Bethany C; Tuerk, Peter W

2014-01-01

In this paper, we consider ethical issues related to the treatment of posttraumatic stress disorder (PTSD) in combat zones, via exposure therapy. Exposure-oriented interventions are the most well-researched behavioral treatments for PTSD, and rigorous studies across contexts, populations, and research groups provide robust evidence that exposure therapy for PTSD is effective and can be widely disseminated. Clinical procedures for Prolonged Exposure therapy, a manualized exposure-oriented protocol for PTSD, are reviewed, and we illustrate the potential benefits, as well as the potential difficulties, associated with providing this treatment in combat zones. Several ethical considerations are identified: (1) Assuming successful treatment, is it ethical to send individuals with a known risk of developing PTSD back into combat? (2) If treatment is unsuccessful in theater (perhaps due to the confounding factor of ongoing danger), could that impact treatment effectiveness for soldiers who attempt therapy again post-deployment? (3) If the military finds combat-zone treatment effective and useful in maintaining an efficient work force, will treatment become mandatory for those diagnosed with PTSD? (4) What unintended consequences might be associated with large-scale dissemination of exposure therapy in or near combat, outside of mental health care infrastructures? (5) How would genetic variations known to be associated with PTSD risk influence decisions regarding who receives treatment or returns to combat? We conclude with a review of the personal and societal costs associated with not providing evidence-based PTSD treatments wherever possible. © 2014 American Society of Law, Medicine & Ethics, Inc.

The apolipoprotein E (APOE) ε4 allele has been implicated in a range of neuropsychiatric conditions. The present research examined if the ε4 allele of the APOE gene moderated the effect of combat exposure on posttraumatic stress disorder (PTSD) among Iraq/Afghanistan-era veterans. Participants included 765 non-Hispanic White (NHW) and 859 non-Hispanic Black (NHB) Iraq/Afghanistan-era veterans. A structured interview established psychiatric diagnoses. Combat exposure and PTSD symptom severity were assessed via self-report. The most common lifetime diagnoses were depression (39.2%), PTSD (38.4%), and alcohol dependence (24.38%). After correcting for multiple comparisons, no significant effects were observed on any of the outcomes among the NHW sample; however, within the NHB sample, significant gene × environment (G × E) interactions were observed for lifetime PTSD (P = .0029) and PTSD symptom severity (P = .0009). In each case, the APOE ε4 allele had no effect on the outcomes when combat exposure was low; however, when combat exposure was high, an additive effect was observed such that ε4 homozygotes exposed to high levels of combat reported the highest rates of PTSD (92%) and the worst symptom severity scores on the Davidson Trauma Scale (M = 79.5). Although preliminary, these findings suggest that the APOE ε4 allele, in conjunction with exposure to high levels of combat exposure, may increase veterans' risk for developing PTSD. © 2015 Wiley Periodicals, Inc.

The existing evidence shows great promise for plasma as the first resuscitation fluid in both civilian and military trauma. We embarked on the Control of Major Bleeding After Trauma (COMBAT) trial with the support of the Department of Defense, in order to determine if plasma-first resuscitation yields hemostatic and survival benefits. The methodology of the COMBAT study represents not only three years of development work, but the integration of nearly two-decades of technical experience with the design and implementation of other clinical trials and studies. Herein, we describe the key features of the study design, critical personnel and infrastructural elements, and key innovations. We will also briefly outline the systems engineering challenges entailed by this study. COMBAT is a randomized, placebo controlled, semi-blinded prospective Phase IIB clinical trial, conducted in a ground ambulance fleet based at a Level I trauma center, and part of a multicenter collaboration. The primary objective of COMBAT is to determine the efficacy of field resuscitation with plasma first, compared to standard of care (normal saline). To date we have enrolled 30 subjects in the COMBAT study. The ability to achieve intervention with a hemostatic resuscitation agent in the closest possible temporal proximity to injury is critical and represents an opportunity to forestall the evolution of the “bloody vicious cycle”. Thus, the COMBAT model for deploying plasma in first response units should serve as a model for RCTs of other hemostatic resuscitative agents. PMID:25784527

Performance and safety are impaired in employees engaged in shift work. Combat divers who use closed-circuit oxygen diving apparatus undergo part of their training during the night hours. The greatest risk involved in diving with such apparatus is the development of central nervous system oxygen toxicity (CNS-OT). We investigated whether the switch from day-to-night activity may be a risk factor for the development of CNS-OT using a diurnal animal model, the fat sand rat (Psammomys obesus). Animals were kept on a 12:12 light-dark schedule (6 a.m. to 6 p.m. at 500 lx). The study included two groups: (1) Control group: animals were kept awake and active during the day, between 09:00 and 15:00. (2) Experimental group: animals were kept awake and active during the night, between 21:00 and 03:00, when they were exposed to dim light in order to simulate the conditions prevalent during combat diver training. This continued for a period of 3 weeks, 5 days a week. On completion of this phase, 6-sulphatoxymelatonin (6-SMT) levels in urine were determined over a period of 24 h. Animals were then exposed to hyperbaric oxygen (HBO). To investigate the effect of acute melatonin administration, melatonin (50 mg/kg) or its vehicle was administered to the animals in both groups 20 min prior to HBO exposure. After the exposure, the activity of superoxide dismutase, catalase and glutathione peroxidase was measured, as were the levels of neuronal nitric oxide synthase (nNOS) and overall nitrotyrosylation in the cortex and hippocampus. Latency to CNS-OT was significantly reduced after the transition from day-to-night activity. This was associated with alterations in the level of melatonin metabolites secreted in the urine. Acute melatonin administration had no effect on latency to CNS-OT in either of the groups. Nevertheless, the activity of superoxide dismutase and catalase, as well as nitrotyrosine and nNOS levels, were altered in the hippocampus following melatonin administration. On the basis of these results, we suggest that a switch from diurnal to nocturnal activity may represent an additional risk factor for the development of CNS-OT. Utilizing a diurnal animal model may contribute to our understanding of the heightened risk of developing CNS-OT when diving with closed-circuit oxygen apparatus at night.

2010-01-01

The effectiveness of games as instructional tools has been debated over the past several decades. This is due to the lack of empirical data to support such claims. The US ARMY developed a game-based simulation to support Tactical Combat Casualty Care (TCCC) Training. The TC3 Game based Simulation is a first person game that allows a Soldier to play the role of a combat medic during an infantry squad mission in an urban environment. This research documents results from a training effectiveness evaluation conducted at the Department of Combat Medic Training (Ft Sam Houston) in an effort to explore the capability of the game based simulation as a potential tool to support the TCCC program of instruction. Reaction to training, as well as, acquisition of knowledge and transfer of skills were explored using Kirkpatrick's Model of Training Effectiveness Evaluation. Results from the evaluation are discussed.

In addition to experiencing traumatic events while deployed in a combat environment, there are other factors that contribute to the development of posttraumatic stress disorder (PTSD) in military service members. This study explored the contribution of genetics, childhood environment, prior trauma, psychological, cognitive, and deployment factors to the development of traumatic stress following deployment. Both pre- and postdeployment data on 231 of 458 soldiers were analyzed. Postdeployment assessments occurred within 30 days from returning stateside and included a battery of psychological health, medical history, and demographic questionnaires; neurocognitive tests; and blood serum for the D2 dopamine receptor (DRD2), apolipoprotein E (APOE), and brain-derived neurotropic factor (BDNF) genes. Soldiers who screened positive for traumatic stress at postdeployment had significantly higher scores in depression (d = 1.91), anxiety (d = 1.61), poor sleep quality (d = 0.92), postconcussion symptoms (d = 2.21), alcohol use (d = 0.63), traumatic life events (d = 0.42), and combat exposure (d = 0.91). BDNF Val66 Met genotype was significantly associated with risk for sustaining a mild traumatic brain injury (mTBI) and screening positive for traumatic stress. Predeployment traumatic stress, greater combat exposure and sustaining an mTBI while deployed, and the BDNF Met/Met genotype accounted for 22% of the variance of postdeployment PTSD scores (R (2)  = 0.22, P < 0.001). However, predeployment traumatic stress, alone, accounted for 17% of the postdeployment PTSD scores. These findings suggest predeployment traumatic stress, genetic, and environmental factors have unique contributions to the development of combat-related traumatic stress in military service members.

2000-03-01

The impact of combat and sexual harassment on the severity of posttraumatic stress disorder (PTSD) is compared for 1,307 men and 197 women peacekeepers who served in the same military units. A theoretical model was proposed to express the nature of the impact. Structural equation modeling was used to evaluate the model separately for men and women. Good-fitting, parsimonious models were developed that showed substantial similarity for men and women. For men, severity of PTSD symptoms was impacted by exposure to combat directly and indirectly through fear and sexual harassment. For women, severity of PTSD symptoms was impacted by combat indirectly through the same two influences, although the mechanisms involving fear and sexual harassment were somewhat different. For both genders, moreover, PTSD severity was impacted directly by exposure to the dying of the Somali people. These similarities suggest that in modern stressful overseas military missions, both genders may be susceptible to the same types of risk for the development of PTSD. The incidence and impact of sexual harassment is particularly noteworthy in the case of men and calls for more detailed investigation in future studies.

Infections have complicated the care of combat casualties throughout history and were at one time considered part of the natural history of combat trauma. Personnel who survived to reach medical care were expected to develop and possibly succumb to infections during their care in military hospitals. Initial care of war wounds continues to focus on rapid surgical care with debridement and irrigation, aimed at preventing local infection and sepsis with bacteria from the environment (e.g., clostridial gangrene) or the casualty's own flora. Over the past 150 years, with the revelation that pathogens can be spread from patient to patient and from healthcare providers to patients (including via unwashed hands of healthcare workers, the hospital environment and fomites), a focus on infection prevention and control aimed at decreasing transmission of pathogens and prevention of these infections has developed. Infections associated with combat-related injuries in the recent operations in Iraq and Afghanistan have predominantly been secondary to multidrug-resistant pathogens, likely acquired within the military healthcare system. These healthcare-associated infections seem to originate throughout the system, from deployed medical treatment facilities through the chain of care outside of the combat zone. Emphasis on infection prevention and control, including hand hygiene, isolation, cohorting, and antibiotic control measures, in deployed medical treatment facilities is essential to reducing these healthcare-associated infections. This review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

Eagle 11 is a prototype analytic model derived from the integration of the low resolution Eagle model with the high resolution SIMNET model. This integration promises a new capability to allow for a more effective examination of proposed or existing combat systems that could not be easily evaluated using either Eagle or SIMNET alone. In essence, Eagle II becomes a multi-resolution combat model in which simulated combat units can exhibit both high and low fidelity behavior at different times during model execution. This capability allows a unit to behave in a highly manner only when required, thereby reducing the overallmore » computational and manpower requirements for a given study. In this framework, the SIMNET portion enables a highly credible assessment of the performance of individual combat systems under consideration, encompassing both engineering performance and crew capabilities. However, when the assessment being conducted goes beyond system performance and extends to questions of force structure balance and sustainment, then SISMNET results can be used to ``calibrate`` the Eagle attrition process appropriate to the study at hand. Advancing technologies, changes in the world-wide threat, requirements for flexible response, declining defense budgets, and down-sizing of military forces motivate the development of manpower-efficient, low-cost, responsive tools for combat development studies. Eagle and SIMNET both serve as credible and useful tools. The integration of these two models promises enhanced capabilities to examine the broader, deeper, more complex battlefield of the future with higher fidelity, greater responsiveness and low overall cost.« less

[DETERMINATION OF THE OPTIMAL SAFE MODE OF PHYSICAL ACTIVITY FOR THE MILITARY SERVANTS UNDER CONDITIONS CLOSE TO FIGHTING].

The paper presents the results of research, allowing to establish the need for and feasibility of an integrated method to determine the most effective but at the same time safe modes of load to the body troops. We found that despite the rather promising application of our proposed mode of load of high intensity (Ra = 0.71) to increase the level of physical military training as soon as possible in time of peace (with a minimum set of combat equipment), problematic issue is that in most cases there is a complete-mismatch achieved in the degree of physical development of the body of military requirements and the challenges posed in terms of direct hostilities. Using the integral method developed by us we determine the safest modes of exercise for the military servants to optimize the most appropriate parameters of volume and intensity of the load, and speed up the adaptive changes in their body to enhance maximum performance at this stage of preparation.

Rating of Perceived Exertion for Quantification of Training and Combat Loads During Combat Sport-Specific Activities: A Short Review.

PubMed

Slimani, Maamer; Davis, Philip; Franchini, Emerson; Moalla, Wassim

2017-10-01

The aim of this short review was to summarize data pertaining to the rating of perceived exertion (RPE) methods (RPE value and session-RPE) during combat sport-specific activities (i.e., competition and training) based on many factors, including contest type (i.e., official vs. simulated vs. training), combat rounds, age of participants and muscle groups, and their correlation with physiological variables (i.e., blood lactate concentration [La] and heart rate [HR]). The current review shows higher RPE in a match of mixed martial arts (MMAs) than Brazilian jiu-jitsu and kickboxing matches and during the competitive period compared with the precompetitive period. This could be explained by the longer duration of bouts, the higher percentage contribution of aerobic metabolism in MMA than other combat sports and contest type differences (simulated vs. official matches). Thus, this review found significant correlations between RPE or session-RPE, [La] and HR. Particularly, there was a stronger correlation between RPE and [La] during official striking (r = 0.81) than grappling combat sports matches (r = 0.53). In addition, a variation of correlation (moderate to large) between session-RPE and HR-based methods has been reported (i.e., Edwards' training load [r ranged between 0.58 and 0.95] and Banister training impulse [r ranged between 0.52 and 0.86]). Specifically, stronger correlation was apparent in combat sport competition that required a much higher percentage contribution of aerobic metabolism (e.g., karate) and in adult athletes than anaerobic-based combat sports (e.g., taekwondo) and young athletes, respectively. Indeed, the current review highlights that the correlations between session-RPE and HR-based methods were higher during official competition than training sessions. Session-RPE was affected by participants' competitive level, the intensity of session (high vs. low), the training modalities (tactical-technical vs. technical-development vs. simulated competition), and the training volume in combat sports athletes. Rating of perceived exertion is a valid tool for quantifying internal training and combat loads during short- and long-term training and simulated and official competitions in novice and elite combat sport athletes. Furthermore, both RPE methods may be a more reliable measure of intensity or effort when both anaerobic and aerobic systems are appreciably activated. Coaches, sports scientists, and athletes can use session-RPE method to quantify short-term training and combat loads in adult athletes during precompetitive period much more than long-term training and in young athletes during the competitive period. They can also use RPE to monitor combat and short- and long-term training loads to better plan and assist training programs and competitions.

Military burns result from either combat or non-combat causes. We compared these etiologies from patients involved in ongoing conflicts to evaluate their impact and provide prevention recommendations. All military patients with significant burns treated at the United States Army Institute of Surgical Research from April 2003 to May 2005 were reviewed. Injuries were categorized as having resulted from combat or non-combat causes. Demographics, burn severity and pattern, mortality, and early outcomes were compared. There were 273 burn patients seen with 63% injured in combat. A high early rate of non-combat injuries was noted. Feedback on non-combat burn prevention was provided to the combat theater, and the incidence of non-combat burns decreased. Mean age and time from injury to admission did not differ. The majority of combat injuries resulted from explosive device detonation. Waste burning, ammunition handling, and gasoline caused most non-combat injuries. Combat casualties had more associated and inhalation injuries and greater full-thickness burn size; total body surface area burned was equivalent. The hands and the face were the most frequently burned body areas. Mortality was 5% in combat and 2% in non-combat patients. The majority of survivors in both groups returned to military duty. The disparity in full-thickness burn size and incidence of inhalation and associated injuries resulted from differing mechanisms of injury, with explosions and penetrating trauma more common in combat wounds. Despite the severity of combat burns, mortality was low and outcomes generally good. Non-combat burns are preventable and have decreased in incidence.

[Military psychiatry in Israel: a 50-year perspective].

Bleich, A

2000-05-01

The history of military psychiatry in Israel may be divided into 2 main periods. The first extended from the War of Independence in 1948, through the Sinai, Six Day and Yom Kippur Wars. Its outstanding feature was avoidance of the issue of combat stress reaction (CSR). The Yom Kippur War made the recognition of CSR inescapable, assisted in breaking up denial, and served as a stimulus for development of the next phase of the system. This second phase was characterized by impressive progress in all areas of military psychiatry. The rich experience accumulated during the wars, together with the assimilation of a research culture which began blooming, especially in the wake of the Lebanon War, aided the development and crystallization of concepts related to combat and non-combat military psychiatry alike. The build-up of the mental health organization overlapped field deployment of the Medical Corps.

Factors determining who develops PTSD following trauma are not well understood. The €4 allele of the apolipoprotein E (apoE) gene is associated with dementia and unfavorable outcome following brain insult. PTSD is also associated with dementia. Given evidence that psychological trauma adversely affects the brain, we hypothesized that the apoE genotype moderates effects of psychological trauma on PTSD pathogenesis. To investigate the moderation of the relationship between PTSD symptoms and combat exposure, we used 172 participants with combat trauma sustained during the Vietnam War. PTSD symptoms were the dependent variable and number of combat experiences, apoE genotype, and the combat experiences × apoE genotype interaction were predictors. We also examined the outcome of a diagnosis of PTSD (n = 39) versus no PTSD diagnosis (n = 131). The combat × apoE genotype interaction was significant for both PTSD symptoms (P = .014) and PTSD diagnosis (P = .009). ApoE genotype moderates the relationship between combat exposure and PTSD symptoms. Although the pathophysiology of PTSD is not well understood, the €4 allele is related to reduced resilience of the brain to insult. Our results are consistent with the €4 allele influencing the effects of psychological trauma on the brain, thereby affecting the risk of PTSD. © 2013 Wiley Periodicals, Inc.

2013-01-01

A retrospective review was performed to evaluate the outcomes and complications following heterotopic ossification (HO) resection and lysis of adhesion procedures for posttraumatic contracture, after combat-related open elbow fractures. From 2004 to 2011, HO resection was performed on 30 blast-injured elbows at a mean 10 months after injury. Injuries included 8 (27%) Gustilo-Anderson type II fractures, 8 (27%) type III-A, 10 (33%) III-B, and 4 (13%) III-C. Mean preoperative flexion-extension range of motion (ROM) was 36.4°, compared with mean postoperative ROM of 83.6°. Mean gain of motion was 47.2°. Traumatic brain injury, need for flap, and nerve injury did not appear to have a significant effect on preoperative or postoperative ROM. Complications included one fracture, six recurrent contractures, and one nerve injury. The results and complications of HO resection for elbow contracture following high-energy, open injuries from blast trauma are generally comparable to those reported for HO resection following lower energy, closed injuries.

Divergent findings from previous research examining gender differences in the development of posttraumatic stress disorder (PTSD) among US military members deployed to the operations in Iraq or Afghanistan (recent operations) prompted this study utilizing a matching approach to examine whether risk for new-onset PTSD and PTSD severity scores differed by gender. US military members from the Millennium Cohort Study deployed in support of the recent operations were followed for approximately 7 years from baseline through 2 follow-up periods between 2001 and 2008. Propensity score matching was used to match 1 male to each female using demographic, military, and behavioral factors including baseline sexual assault. Analyses were stratified by combat experience defined as reporting at least one of five exposures during follow-up. Outcome measures included a positive screen for PTSD and severity scores measured by the PTSD Patient Checklist-Civilian Version. Discrete-time survival analysis quantified the association between gender and incident PTSD. Among 4684 matched subjects (2342 women and men), 6.7% of women and 6.1% of men developed PTSD during follow-up. Results showed no significant gender differences for the likelihood of developing PTSD or for PTSD severity scores among women and men who reported combat experience and among those who did not. This study is the first of its kind to match a large population of male and female service members on important baseline characteristics including sexual assault. Findings suggest that while combat deployed personnel develop PTSD, women do not have a significantly different risk for developing PTSD than men after experiencing combat.

This article describes the development of two graphic novels as a new approach to mental health communication and coping strategies for the Navy and Marine Corps. The novels are intended to capture the attention of the younger target audience and provide vital teaching messages to better prepare personnel for deployment to combat zones. The novels were developed based on embedding the principles of combat and operational stress control (COSC) into realistic and relatable characters, stories, and images. Approaches used for development included (a) basing storylines on real-life service members and the situations they face in combat and their personal lives; (b) partnering with COSC experts to embed teaching points; (c) ensuring technical accuracy through research and target audience reviews of the storyboard and artwork; (d) developing characters that are representative of the target audience, with varied jobs, ages, backgrounds, and professional concerns; and (e) designing artwork in a manner sensitive to training objectives and the psychological effects on readers. Because technical accuracy, realism, and sensitivity were noted as essential components of an effective graphic novel tool, focus-group research and review of author drafts by the target audience and technical experts are strongly recommended.

Combat sports involve body contact through striking, kicking and/or throwing. They are anecdotally referred to as 'dangerous', yet long-term investigation into specific injury rates is yet to be explored. To describe incidence and prevalence of injury and illness within Olympic combat sports and to investigate risk of bias of prospective injury and illness research within these sports. We systematically searched literature published up until May 2016. We included prospective studies of injury/illness in elite combat athletes lasting more than 12 weeks. Risk of bias was assessed using a modified version of the Downs and Black checklist for methodological quality. Included studies were mapped to the Oxford Centre for Evidence-Based Medicine levels of evidence. Nine studies were included, and most (n=6) had moderate risk of bias. Studies provided level 1/2b evidence that the most frequently injured areas were the head/face (45.8%), wrist (12.0%) and lower back (7.8%) in boxing; the lower back (10.9%), shoulder (10.2%) and knee (9.7%) in judo; the fingers (22.8%) and thigh (9.1%) in taekwondo; and the knee (24.8%), shoulder (17.8%) and head/face (16.6%) in wrestling. Heterogeneity of injury severity classifications and inconsistencies inexposure measures prevented any direct comparisons of injury severity/incidence across combat sports. There is currently a lack of consensus in the collection of injury/illness data, limiting the development of prevention programmes for combat sport as a whole. However, sport-specific data that identify body areas with high injury frequency can provide direction to clinicians, enabling them to focus their attention on developing pathologies in these areas. In doing so, clinicians can enhance the practical elements of their role within the integrated combat sport performance team and assist in the regular update of surveillance records. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Development of a neural net paradigm that predicts simulator sickness

Allgood, G.O.

1993-03-01

A disease exists that affects pilots and aircrew members who use Navy Operational Flight Training Systems. This malady, commonly referred to as simulator sickness and whose symptomatology closely aligns with that of motion sickness, can compromise the use of these systems because of a reduced utilization factor, negative transfer of training, and reduction in combat readiness. A report is submitted that develops an artificial neural network (ANN) and behavioral model that predicts the onset and level of simulator sickness in the pilots and aircrews who sue these systems. It is proposed that the paradigm could be implemented in real timemore » as a biofeedback monitor to reduce the risk to users of these systems. The model captures the neurophysiological impact of use (human-machine interaction) by developing a structure that maps the associative and nonassociative behavioral patterns (learned expectations) and vestibular (otolith and semicircular canals of the inner ear) and tactile interaction, derived from system acceleration profiles, onto an abstract space that predicts simulator sickness for a given training flight.« less

A piloted simulation investigation of yaw dynamics requirements for turreted gun use in low-level helicopter air combat

NASA Technical Reports Server (NTRS)

Decker, William A.; Morris, Patrick M.; Williams, Jeffrey N.

1988-01-01

A piloted, fixed-base simulation study was conducted to investigate the handling qualities requirements for helicopter air-to-air combat using turreted guns in the near-terrain environment. The study used a version of the helicopter air combat system developed at NASA Ames Research Center for one-on-one air combat. The study focused on the potential trade-off between gun angular movement capability and required yaw axis response. Experimental variables included yaw axis response frequency and damping and the size of the gun-movement envelope. A helmet position and sighting system was used for pilot control of gun aim. Approximately 340 simulated air combat engagements were evaluated by pilots from the Army and industry. Results from the experiment indicate that a highly-damped, high frequency yaw response was desired for Level I handling qualities. Pilot preference for those characteristics became more pronounced as gun turret movement was restricted; however, a stable, slow-reacting platform could be used with a large turret envelope. Most pilots preferred to engage with the opponent near the own-ship centerline. Turret elevation restriction affected the engagement more than azimuth restrictions.

This information-sharing relationship is built upon a strong legislative foundation and effective operational procedures. As with money-laundering and terrorist financing, halting the illicit procurement of dual-use commodities requires close coordination between government and industry. However, many of the legal and operational features present in financial threat cooperation do not exist in the export control realm. This article analyzes the applicability of financial industry cooperative measures to nonproliferation.

An improved spectacle frame has been developed for use during periods of extreme physical activity, particularly by military personnel during combat operations, and which can be used under protective face masks and headgear. The frame has a wrap-around shape, made of nylon with a contoured, recessed bridge and safety lens groove. U-shaped bridles snap on the frame front and an adjustable, interlocking strap fits over the bridles and passes under a protective mask sealing area. Field tests were conducted with 1231 soldiers at 12 military installations. Over 90% of those tested found combat spectacles were comfortable to wear, extremely durable, compatible with headgear and superior to existing military eyewear.

Herpes Simplex Vaccines: Prospects of Live-attenuated HSV Vaccines to Combat Genital and Ocular infections

PubMed Central

Stanfield, Brent; Kousoulas, Konstantin Gus

2015-01-01

Herpes simplex virus type-1 (HSV-1) and its closely related type-2 (HSV-2) viruses cause important clinical manifestations in humans including acute ocular disease and genital infections. These viruses establish latency in the trigeminal ganglionic and dorsal root neurons, respectively. Both viruses are widespread among humans and can frequently reactivate from latency causing disease. Currently, there are no vaccines available against herpes simplex viral infections. However, a number of promising vaccine approaches are being explored in pre-clinical investigations with few progressing to early phase clinical trials. Consensus research findings suggest that robust humoral and cellular immune responses may partially control the frequency of reactivation episodes and reduce clinical symptoms. Live-attenuated viral vaccines have long been considered as a viable option for generating robust and protective immune responses against viral pathogens. Varicella zoster virus (VZV) belongs to the same alphaherpesvirus subfamily with herpes simplex viruses. A live-attenuated VZV vaccine has been extensively used in a prophylactic and therapeutic approach to combat primary and recurrent VZV infection indicating that a similar vaccine approach may be feasible for HSVs. In this review, we summarize pre-clinical approaches to HSV vaccine development and current efforts to test certain vaccine approaches in human clinical trials. Also, we discuss the potential advantages of using a safe, live-attenuated HSV-1 vaccine strain to protect against both HSV-1 and HSV-2 infections. PMID:27114893

Mixed-Handedness in Identical Twins Discordant for Combat Exposure in Vietnam: Relationship to Posttraumatic Stress Disorder.

PubMed

Goetz, Jared M; Pitman, Seth R; Tanev, Kaloyan S; Pitman, Roger K; Chemtob, Claude M

2016-01-01

This study evaluated the degree of mixed-handedness in predominantly right-handed Vietnam combat veteran twins and their identical, combat-unexposed cotwins. The "high-risk" cotwins of combat veterans with combat-related posttraumatic stress disorder (PTSD) had more mixed-handedness (i.e., less right-handedness) than the "low-risk" cotwins of combat veterans without PTSD. Self-reported combat exposure in combat-exposed twins was a mediator of the association between handedness in their unexposed cotwins and PTSD in the twins themselves. We conclude that mixed-handedness is a familial risk factor for combat-related PTSD. This risk may be mediated in part by a proclivity for mixed-handed soldiers and Marines to experience heavier combat.

Risk factors for closed-head injuries during military airborne operations.

One of the more serious adverse outcomes of military airborne operations is closed-head injuries. This investigation examined risk factors for closed-head injuries in an Army airborne infantry unit. Closed-head injuries were defined as energy exchanges in which the head contacted the ground or an object and the soldier sought medical care for external trauma, headache, loss of consciousness, or altered mental state. Injury data were obtained by investigators in the drop zone and diagnoses were confirmed by a physician. Operational data on potential injury risk factors were obtained from routine reports published by the infantry unit. Weather data were obtained using a pocket weather tracker. There were 96,132 jumps resulting in 310 closed-head injuries for a crude incidence of 3.22/1000 jumps. In 98% of known cases the injury was associated with parachute landings. Multivariate logistic regression revealed that independent risk factors for closed-head injuries included night jumps, combat loads, higher wind speeds, higher temperatures, enlisted rank, and entanglements. This study identifies the current incidence and extrinsic risk factors for closed-head injuries during military airborne operations. Although it is necessary to conduct airborne training under realistic conditions, trainers and commanders should be aware of these risks and plan airborne operations accordingly.

The NASA F-18 HARV was a testbed to produce aerodynamic data at high angles of attack to validate computer codes and wind tunnel research. The X-31 was used to study thrust vectoring to enhance close-in air combat maneuvering, while the F-16 MATV was a demonstration of how thrust vectoring could be applied to operational aircraft.

Noise reduction, restoration, and segmentation methods are developed for the quantitative structural analysis in three dimensions of aggregated oil-in-water emulsion systems imaged by fluorescence confocal laser scanning microscopy. Mindful of typical industrial formulations, the methods are demonstrated for concentrated (30% volume fraction) and polydisperse emulsions. Following a regularized deconvolution step using an analytic optical transfer function and appropriate binary thresholding, novel application of the Euclidean distance map provides effective discrimination of closely clustered emulsion droplets with size variation over at least 1 order of magnitude. The a priori assumption of spherical nonintersecting objects provides crucial information to combat the ill-posed inverse problem presented by locating individual particles. Position coordinates and size estimates are recovered with sufficient precision to permit quantitative study of static geometrical features. In particular, aggregate morphology is characterized by a novel void distribution measure based on the generalized Apollonius problem. This is also compared with conventional Voronoi/Delauney analysis.

Neural response to errors in combat-exposed returning veterans with and without post-traumatic stress disorder: a preliminary event-related potential study.

Post-traumatic stress disorder (PTSD) is characterized by sustained anxiety, hypervigilance for potential threat, and hyperarousal. These symptoms may enhance self-perception of one's actions, particularly the detection of errors, which may threaten safety. The error-related negativity (ERN) is an electrocortical response to the commission of errors, and previous studies have shown that other anxiety disorders associated with exaggerated anxiety and enhanced action monitoring exhibit an enhanced ERN. However, little is known about how traumatic experience and PTSD would affect the ERN. To address this gap, we measured the ERN in returning Operation Enduring Freedom/Operation Iraqi Freedom (OEF/OIF) veterans with combat-related PTSD (PTSD group), combat-exposed OEF/OIF veterans without PTSD [combat-exposed control (CEC) group], and non-traumatized healthy participants [healthy control (HC) group]. Event-related potential and behavioral measures were recorded while 16 PTSD patients, 18 CEC, and 16 HC participants completed an arrow version of the flanker task. No difference in the magnitude of the ERN was observed between the PTSD and HC groups; however, in comparison with the PTSD and HC groups, the CEC group displayed a blunted ERN response. These findings suggest that (1) combat trauma itself does not affect the ERN response; (2) PTSD is not associated with an abnormal ERN response; and (3) an attenuated ERN in those previously exposed to combat trauma but who have not developed PTSD may reflect resilience to the disorder, less motivation to do the task, or a decrease in the significance or meaningfulness of 'errors,' which could be related to combat experience.

Hemorrhage remains the leading cause of combat death and a major cause of death from potentially survivable injuries. Great strides have been made in controlling extremity hemorrhage with tourniquets, but not all injuries are amenable to tourniquet application. Topical hemostatic agents and dressings have also contributed to success in controlling extremity and compressible junctional hemorrhage, and their efficacy continues to increase as enhanced products are developed. Since the addition of Combat Gauze™ (Z-Medica Corporation, Wallingford, CT, USA; http://www.z-medica.com/) in April 2008 to the Tactical Combat Casualty Care (TCCC) Guidelines, there are consistent data from animal studies of severe hemorrhage that chitosan-based hemostatic gauze dressings developed for battlefield application are, at least, equally efficacious as Combat Gauze. Successful outcomes are also reported using newer chitosan-based dressings in civilian hospital-based surgical case reports and prehospital (battlefield) case reports and series. Additionally, there have been no noted complications or safety concerns in these cases or across many years of chitosan-based hemostatic dressing use in both the military and civilian prehospital sectors. Consequently, after a decade of clinical use, there is added benefit and a good safety record for using chitosan-based gauze dressings. For these reasons, many specific US military Special Operations Forces, NATO militaries, and emergency medical services (EMS) and law enforcement agencies have already implemented the widespread use of these new recommended chitosan-based hemostatic dressings. Based on the past battlefield success, this report proposes to keep Combat Gauze as the hemostatic dressing of choice along with the new addition of Celox™ Gauze (Medtrade Products Ltd., Crewe, UK; http://www.celoxmedical.com/usa/products /celox-gauze/) and ChitoGauze® (HemCon Medical Technologies, Portland, OR, USA; http://www.hemcon.com/) to the TCCC Guidelines. 2014.

The world's drylands are subject to desertification as a result of extended droughts, climate change, and human activities. Development in drylands depends on addressing degradation of the ecosystem, mainstreaming sustainable natural resources management, and building upon the existing adaptive capacities of communities and institutions. In this regard, recent scientific results aimed to promote sustainable development through action plans for combating desertification. In India, under the Integrated Mission for Sustainable Development (IMSD) programme, remote sensing based integrated land and water resource studies were carried out with an objective to generate locale specific action plans for sustainable development of a region. A specific study was carried out, in districts of Jhabua and Dhar, in Madhya Pradesh using Composite Land Development Sites (CLDS) approach for forest and wasteland development and soil and water conservation. Various treatments were suggested and implemented in 1995. The present study was carried out with an objective to monitor the positive impacts of combating plan implementation through visual interpretation and NDVI analysis of temporal images of LISS III data, since 1991 to 2013. The study reveals that there is substantial increase in the area of irrigated agricultural land with increase in number of check dams along with the stream channels.

Assured Mission Support Space Architecture (AMSSA) study

Hamon, Rob

1993-01-01

The assured mission support space architecture (AMSSA) study was conducted with the overall goal of developing a long-term requirements-driven integrated space architecture to provide responsive and sustained space support to the combatant commands. Although derivation of an architecture was the focus of the study, there are three significant products from the effort. The first is a philosophy that defines the necessary attributes for the development and operation of space systems to ensure an integrated, interoperable architecture that, by design, provides a high degree of combat utility. The second is the architecture itself; based on an interoperable system-of-systems strategy, it reflects a long-range goal for space that will evolve as user requirements adapt to a changing world environment. The third product is the framework of a process that, when fully developed, will provide essential information to key decision makers for space systems acquisition in order to achieve the AMSSA goal. It is a categorical imperative that military space planners develop space systems that will act as true force multipliers. AMSSA provides the philosophy, process, and architecture that, when integrated with the DOD requirements and acquisition procedures, can yield an assured mission support capability from space to the combatant commanders. An important feature of the AMSSA initiative is the participation by every organization that has a role or interest in space systems development and operation. With continued community involvement, the concept of the AMSSA will become a reality. In summary, AMSSA offers a better way to think about space (philosophy) that can lead to the effective utilization of limited resources (process) with an infrastructure designed to meet the future space needs (architecture) of our combat forces.

2010-01-01

The Information Age Combat Model (IACM) was introduced by Cares in 2005 to contribute to the development of an understanding of the influence of connectivity on force effectiveness that can eventually lead to quantitative prediction and guidelines for design and employment. The structure of the IACM makes it clear that the Perron-Frobenius Eigenvalue is a quantifiable metric with which to measure the organization of a networked force. The results of recent experiments presented in Deller, et aI., (2009) indicate that the value of the Perron-Frobenius Eigenvalue is a significant measurement of the performance of an Information Age combat force. This was accomplished through the innovative use of an agent-based simulation to model the IACM and represents an initial contribution towards a new generation of combat models that are net-centric instead of using the current platform-centric approach. This paper describes the intent, challenges, design, and initial results of this agent-based simulation model.

Longitudinal Changes in Combat-Related Posttraumatic Stress Disorder Among Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn Veterans With Hazardous Alcohol Use: The Role of Avoidance Coping.

PubMed

Lee, Joohyun; Possemato, Kyle; Ouimette, Paige C

2017-10-01

Military personnel who have experienced combat trauma are at risk for developing posttraumatic stress disorder (PTSD). A greater recognition of the complex array of vulnerability factors that contribute to PTSD severity has led researchers to examine other non-combat-related factors. This longitudinal study examined a number of pre-, peri-, and postdeployment factors hypothesized to contribute to PTSD symptomatology among returning Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans presenting with at least subthreshold PTSD symptoms and hazardous alcohol use in a primary care setting. Purported risk factors included childhood family environment, severity of combat exposure, postdeployment social support, alcohol dependence severity, and an avoidant coping style. At baseline, postdeployment social support and avoidant coping contributed to PTSD severity. Only avoidant coping was associated with changes in PTSD symptom at 1-year follow-up. Reducing avoidant coping may deter the maintenance of PTSD among veterans with PTSD symptoms and hazardous alcohol use.

Surgical and Resuscitation Capabilities for the "Next War" Based on Lessons Learned From "This War".

Freel, David; Warr, Bradley J

2016-01-01

The Army gleaned many lessons regarding the provision of medical care to casualties during the past 14 years of combat. Using these lessons learned in the Joint Capabilities and Integration Development process and through the analysis of an integrated process action team, the Army recently approved 3 changes to medical organizations that are intended to provide trauma management farther forward on the battlefield. These changes include the substitution of an emergency medicine trained physician and emergency medicine physician assistant (PA) in lieu of a general medical officer and primary care PA within the brigade combat team; reorganization of the forward surgical team into a forward surgical and resuscitative team; and the modularization of the traditional 248 bed combat support hospital. The Army anticipates that these changes related to personnel, organizations, doctrine, and materiel will enable Army medicine to provide enhanced trauma management closer to the point of a combatant's injury. These modifications are projected to begin in fiscal year 2016.

The Impact of Combat Status on Veterans' Attitudes Toward Help Seeking: The Hierarchy of Combat Elitism.

PubMed

Ashley, Wendy; Brown, Jodi Constantine

2015-01-01

Many veterans do not seek assistance for mental health concerns despite the staggering prevalence of trauma-related symptomatology. Barriers to service provision include personal and professional stigma and inter-veteran attitudes that dictate who is more or less deserving of services. Veteran attitudes are shaped by military culture, which promotes a hyper-masculine paradigm upholding combat experience as the defining feature of the "ideal soldier." The stratification of soldiers into combat or non-combat status creates a hierarchy of combat elitism that extends far beyond active duty. This pilot study surveyed veterans (n = 24) to explore how combat experience may affect attitudes toward help seeking. Findings indicate combat and non-combat veterans are less accepting of non-combat veterans' help-seeking behavior, supporting the notion that veterans' attitudes toward help seeking are influenced by combat status. Despite limitations, the results of this study reflect a need for increased attention to the attitudes veterans have about each other and themselves.

This study aimed to evaluate the relationship between physiological, and parameters of performance analysis during karate contest. Nine elite-level karate athletes participated in this study. Saliva sample was collected pre- and post-karate combat. Salivary cortisol (sC) post-combat 2 raised significantly compared to that recorded at pre-combat 1 (Δ%=105.3%; P=0.04; dz=0.78). The largest decrease of the salivary T/C ratio (sR) compared to pre-combat 1 was recorded post-combat 2 (Δ%=-43.5%; P=0.03). Moreover, blood lactate concentration post-combat 1 correlated positively to sCpost-combat 1 (r=0.66; P=0.05) and negatively to both salivary testosterone (sT) (r=-0.76; P=0.01) and sRpost-combat 1 (r=-0.76; P=0.01). There was no significant relationship between hormonal measures and parameters of match analysis. Although under simulated condition, karate combat poses large physiological stress to the karateka. Additionally, physiological strain to karate combat led to a catabolic hormonal response.

Combating healthcare corruption and fraud with improved global health governance.

Corruption is a serious threat to global health outcomes, leading to financial waste and adverse health consequences. Yet, forms of corruption impacting global health are endemic worldwide in public and private sectors, and in developed and resource-poor settings alike. Allegations of misuse of funds and fraud in global health initiatives also threaten future investment. Current domestic and sectorial-level responses are fragmented and have been criticized as ineffective. In order to address this issue, we propose a global health governance framework calling for international recognition of "global health corruption" and development of a treaty protocol to combat this crucial issue.

Brain-derived neurotrophic factor (BDNF) plays a crucial role in modulating resilience and vulnerability to stress. The aim of this study was to investigate whether epigenetic regulation of the BDNF gene is a biomarker of post-traumatic stress disorder (PTSD) development among veterans exposed to combat in the Vietnam War. Using the Clinician-Administered PTSD Scale, combat veterans were grouped into those with (n = 126) and without (n = 122) PTSD. DNA methylation levels at four CpG sites within the BDNF promoter I region were quantified in the peripheral blood using pyrosequencing. The effects of BDNF DNA methylation levels and clinical variables on the diagnosis of PTSD were tested using binary logistic regression analysis. Subjects with PTSD showed a higher DNA methylation of four CpG sites at the BDNF promoter compared with those without PTSD. High methylation levels at the BDNF promoter CpG site, high combat exposure, and alcohol problems were significantly associated with PTSD diagnosis. This study demonstrated an association between higher DNA methylation of the BDNF promoter and PTSD diagnosis in combat-exposed individuals. Our findings suggest that altered BDNF methylation may be a valuable biomarker of PTSD after trauma exposure. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Clemente-Suárez, Vicente J; Robles-Pérez, José J

2013-09-01

In current theaters of operation, soldiers had to face a different situation as symmetrical (defined battlefield) and asymmetrical combat (non-defined battlefield), especially in urban areas. The mechanical and organic responses of soldiers in these combats are poorly studied in specific literature. This research aimed to analyze physical, mechanical, and physiological parameters during symmetrical and asymmetrical combat simulations. We analyzed 20 soldiers from the Spanish Army and Spanish Forces and Security Corps (34.5 ± 4.2 years; 176.4 ± 8.4 cm; 74.6 ± 8.7 kg; 63.3 ± 8.0 kg muscular mass; 7.6 ± 3.2 kg fat mass) during a symmetric combat (traditional combat simulation) and during an asymmetrical combat (urban combat simulation). Heart rate (HR), speed, sprints, distances, impact, and body load parameters were measured by a GPS system and a HR belt. Results showed many differences between symmetrical and asymmetrical combat. Asymmetrical combat presented higher maximum velocity movement, number of sprints, sprint distance, and average HR. By contrary, symmetric combat presented higher number of impact and body load. This information could be used to improve specific training programs for each type of combat.

Towards a Determination of the Physiological Characteristics Distinguishing Successful Mixed Martial Arts Athletes: A Systematic Review of Combat Sport Literature.

PubMed

James, Lachlan P; Haff, G Gregory; Kelly, Vincent G; Beckman, Emma M

2016-10-01

Mixed martial arts (MMA) is a combat sport underpinned by techniques from other combat disciplines, in addition to strategies unique to the sport itself. These sports can be divided into two distinct categories (grappling or striking) based on differing technical demands. Uniquely, MMA combines both methods of combat and therefore appears to be physiologically complex requiring a spectrum of mechanical and metabolic qualities to drive performance. However, little is known about the physiological characteristics that distinguish higher- from lower-level MMA athletes. Such information provides guidance for training interventions, performance testing and talent identification. Furthermore, while MMA incorporates techniques from both grappling and striking sports, it is unknown precisely how these disciplines differ physiologically. Understanding the relationship between higher-level competitors in grappling and striking combat sports can provide further insight into the development of the optimal performance profile of a higher-level MMA athlete. This article aims to analyse the scientific literature on MMA and the primary combat sports underpinning it to determine the physiological adaptations that distinguish superior competitors, with a view to defining the optimal physiological profile for higher-level MMA performance. Furthermore, this article will explore the differences in these capabilities between grappling- and striking-based combat sports in the context of MMA. A literature search was undertaken via PubMed, Web of Science, SportDiscus and Google Scholar. The following sports were included for systematic review based on their relevance to MMA: mixed martial arts, boxing, Brazilian jiu-jitsu, judo, karate, kickboxing, Muay Thai and wrestling. The inclusion criteria allowed studies that compared athletes of differing competition levels in the same sport using a physiological performance measure. Only male, adult (aged 17-40 years), able-bodied competitors were included. The search history spanned from the earliest record until September 2015. Of the eight combat sports searched for, five were represented across 23 studies. Sixteen investigations described maximal strength or neuromuscular power variables, while 19 articles reported anaerobic or aerobic measures. The results indicate that a number of strength, neuromuscular power and anaerobic variables distinguished higher- from lower-level combat sport athletes. However, these differences were less clear when groups were stratified within, rather than between competition grades. Greater aerobic power was generally not present amongst superior combat sport competitors. There appear to be differing physiological profiles between more successful grappling and striking combat sport athletes. This is represented by high-force demands of grappling sports causing an upwards shift of the entire force-velocity relationship driven by an increase in maximal strength. In comparison, smaller increases in maximal force production with more notable enhancements in lighter load, higher velocity actions may better identify superior performance in striking sports. Anaerobic capabilities largely distinguished higher- from lower-level combat sport athletes. In particular, longer-term anaerobic efforts seem to define successful grappling-based athletes, while superior competitors in striking sports tend to show dominance in shorter-term measures when compared with their lower-level counterparts. Given the demand for both forms of combat in MMA, a spectrum of physiological markers may characterize higher-level competitors. Furthermore, the performance profile of successful MMA athletes may differ based on combat sport history or competition strategy.

Breakdowns in the ethical conduct of soldiers towards non-combatants on the battlefield are of grave concern in war. Evidence-based training approaches to prevent unethical conduct are scarce. We assessed the effectiveness of battlefield-ethics training and factors associated with unethical battlefield conduct. The training package, based on movie vignettes and leader-led discussions, was administered 7 to 8 months into a 15-month high-intensity combat deployment in Iraq, between Dec 11, 2007, and Jan 30, 2008. Soldiers from an infantry brigade combat team (total population about 3500) were randomly selected, on the basis of company and the last four digits of each soldier's social security number, and invited to complete an anonymous survey 3 months after completion of the training. Reports of unethical behaviour and attitudes in this sample were compared with a randomly selected pre-training sample from the same brigade. The response patterns for ethical behaviour and reporting of ethical violations were analysed with chi-square analyses. We developed two logistic regression models using self-reported unethical behaviours as dependent variables. Factors associated with unethical conduct, including combat experiences and post-traumatic stress disorder (PTSD), were assessed with validated scales. Of 500 randomly selected soldiers 421 agreed to participate in the anonymous post-training survey. A total of 397 soldiers of the same brigade completed the pre-training survey. Training was associated with significantly lower rates of unethical conduct of soldiers and greater willingness to report and address misconduct than in those before training. For example, reports of unnecessary damage or destruction of private property decreased from 13·6% (54 of 397; 95% CI 10·2-17·0) before training to 5·0% (21 of 421; 2·9-7·1) after training (percent difference -63·2%; p<0·0001), and willingness to report a unit member for mistreatment of a non-combatant increased from 36·0% (143 of 397; 31·3-40·7) to 58·9% (248 of 421; 54·2-63·6; percent difference 63·6; p<0·0001). Nearly all participants (410 [97%]) reported that training made it clear how to respond towards non-combatants. Combat frequency and intensity was the strongest predictor of unethical behaviour; PTSD was not a significant predictor of unethical behaviour after controlling for combat experiences. Leader-led battlefield ethics training positively influenced soldiers' understanding of how to interact with and treat non-combatants, and reduced reports of ethical misconduct. Unethical battlefield conduct was associated with high-intensity combat but not with PTSD. None. Copyright © 2011 Elsevier Ltd. All rights reserved.

Anecdotal reports from military conflicts suggest cognitive performance and mood are severely degraded by the stress of combat. However, little objective information is available to confirm these observations. Our laboratory had several unique opportunities to study cognitive function in warfighters engaged in exercises designed to simulate the stress of combat. These studies were conducted in different environments with two different types of military volunteers. In one study, subjects were officers, with an average 9 yr of military service, who were members of an elite U.S. Army unit, the Rangers. In the other study, participants were younger, mostly enlisted, trainees with only 3 yr of military experience on average, in training to determine if they would qualify for an elite U.S. Navy unit, the SEALS. We administered a variety of identical, computer-based cognitive tests to both groups. In both groups, during stressful combat-like training, every aspect of cognitive function assessed was severely degraded compared with baseline, pre-stress performance. Relatively simple cognitive functions such as reaction time and vigilance were significantly impaired, as were more complex functions, including memory and logical reasoning. The deficits observed were greater than those typically produced by alcohol intoxication, treatment with sedating drugs, or clinical hypoglycemia. Undoubtedly, such decrements would severely degrade operational effectiveness. Furthermore, it is likely such cognitive decrements would be greater during actual combat. War planners, doctrine developers, and warfighters, especially leaders, need to be aware that combat stress will result in extensive and severe deficits in cognitive performance.

Background In Somalia, a large number of active and former combatants are affected by psychological problems such as Posttraumatic Stress Disorder (PTSD). This disorder impairs their ability to re-integrate into civilian life. However, many screening instruments for Posttraumatic Stress Disorder used in post-conflict settings have limited validity. Here we report on development and validation of a screening tool for PTSD in Somali language with a sample of ex-combatants. Methods We adapted the Posttraumatic Diagnostic Scale (PDS) to reflect linguistic and cultural differences within the Somali community so that local interviewers could be trained to administer the scale. For validation purposes, a randomly selected group of 135 Somali ex-combatants was screened by trained local interviewers; 64 of them were then re-assessed by trained clinical psychologists using the Composite International Diagnostic Interview (CIDI) and the Self-Report Questionnaire (SRQ-20). Results The screening instrument showed good internal consistency (Cronbach's α = .86), convergent validity with the CIDI (sensitivity = .90; specificity = .90) as well as concurrent validity: positive cases showed higher SRQ-20 scores, higher prevalence of psychotic symptoms, and higher levels of intake of the local stimulant drug khat. Compared to a single cut-off score, the multi-criteria scoring, in keeping with the DSM-IV, produced more diagnostic specificity. Conclusion The results provide evidence that our screening instrument is a reliable and valid method to detect PTSD among Somali ex-combatants. A future Disarmament, Demobilization and Reintegration Program in Somalia is recommended to screen for PTSD in order to identify ex-combatants with special psycho-social needs. PMID:17822562

Intelligently interactive combat simulation

Fogel, Lawrence J.; Porto, Vincent W.; Alexander, Steven M.

2001-09-01

To be fully effective, combat simulation must include an intelligently interactive enemy... one that can be calibrated. But human operated combat simulations are uncalibratable, for we learn during the engagement, there's no average enemy, and we cannot replicate their culture/personality. Rule-based combat simulations (expert systems) are not interactive. They do not take advantage of unexpected mistakes, learn, innovate, and reflect the changing mission/situation. And it is presumed that the enemy does not have a copy of the rules, that the available experts are good enough, that they know why they did what they did, that their combat experience provides a sufficient sample and that we know how to combine the rules offered by differing experts. Indeed, expert systems become increasingly complex, costly to develop, and brittle. They have face validity but may be misleading. In contrast, intelligently interactive combat simulation is purpose- driven. Each player is given a well-defined mission, reference to the available weapons/platforms, their dynamics, and the sensed environment. Optimal tactics are discovered online and in real-time by simulating phenotypic evolution in fast time. The initial behaviors are generated randomly or include hints. The process then learns without instruction. The Valuated State Space Approach provides a convenient way to represent any purpose/mission. Evolutionary programming searches the domain of possible tactics in a highly efficient manner. Coupled together, these provide a basis for cruise missile mission planning, and for driving tank warfare simulation. This approach is now being explored to benefit Air Force simulations by a shell that can enhance the original simulation.

Based on the worldwide prevalence of multidrug-resistant strains of Pseudomas aeruginosa and the fact that no newer antipseudomonal agents are available, this article aims to investigate therapeutic solutions for combating infections caused by P aeruginosa, including multidrug-resistant strains. The article focuses mainly on colistin, the re-emerging old antibiotic that possesses prominent antipseudomonal activity in vitro and on doripenem, a newer carbapenem that seems to be close to its global marketing. Regarding older antipseudomonal antibiotics that have been reviewed extensively, only newer aspects on their use are considered in this article.

There is a need for more work to understand the quality of life (QOL) outcomes of survivors of Operations Enduring Freedom and Iraqi Freedom combat injury to improve care and treatment, and prevent poor physical, psychological, and social outcomes. We describe the study design and methods of the Wounded Warrior Recovery Project, a study supported by the Department of Defense that will track close to 10,000 military personnel wounded in Operations Enduring Freedom and Iraqi Freedom. The overall objective of the 6-year longitudinal study is to track changes in QOL and describe variations in those changes as they relate to sociodemographic factors, injury characteristics, service-related factors, clinical/diagnostic measures including traumatic brain injury and posttraumatic stress disorder, and medical procedures and services. The Wounded Warrior Recovery Project study will be among the first longitudinal population-based investigations of QOL outcomes after combat injury and will provide a basis upon which large-scale epidemiological studies can be conducted.

Objectives To discover whether post-combat syndromes have existed after modern wars and what relation they bear to each other. Design Review of medical and military records of servicemen and cluster analysis of symptoms. Data sources Records for 1856 veterans randomly selected from war pension files awarded from 1872 and from the Medical Assessment Programme for Gulf war veterans. Main outcome measures Characteristic patterns of symptom clusters and their relation to dependent variables including war, diagnosis, predisposing physical illness, and exposure to combat; and servicemen's changing attributions for post-combat disorders. Results Three varieties of post-combat disorder were identified—a debility syndrome (associated with the 19th and early 20th centuries), somatic syndrome (related primarily to the first world war), and a neuropsychiatric syndrome (associated with the second world war and the Gulf conflict). The era in which the war occurred was overwhelmingly the best predictor of cluster membership. Conclusions All modern wars have been associated with a syndrome characterised by unexplained medical symptoms. The form that these assume, the terms used to describe them, and the explanations offered by servicemen and doctors seem to be influenced by advances in medical science, changes in the nature of warfare, and underlying cultural forces. What is already known on this topicService in the Gulf war is associated with an increased rate of reported symptoms and worsening subjective healthPost-combat syndromes have been described after most modern conflicts from the US civil war onwardsWhat this study addsThere seems to be no single post-combat syndrome but a number of variations on a themeThe ever changing form of post-combat syndromes seems to be related to advances in medical understanding, the developing nature of warfare, and cultural undercurrentsBecause reported symptoms are subject to bias and changing emphasis related to advances in medical science or the discovery of new diseases, the characterisation of individual syndromes has to be treated with cautionAttributions by servicemen are generally consistent with symptom characteristics, though there seems to be a growing reluctance to consider the stress of military service as a cause PMID:11834557

The Spanish Ministry of Defense, through its Future Combatant program, has sought to develop technology aids with the aim of extending combatants' operational capabilities. Within this framework the ATREC project funded by the “Coincidente” program aims at analyzing diverse biometrics to assess by real time monitoring the stress levels of combatants. This project combines multidisciplinary disciplines and fields, including wearable instrumentation, textile technology, signal processing, pattern recognition and psychological analysis of the obtained information. In this work the ATREC project is described, including the different execution phases, the wearable biomedical measurement systems, the experimental setup, the biomedical signal analysis and speech processing performed. The preliminary results obtained from the data analysis collected during the first phase of the project are presented, indicating the good classification performance exhibited when using features obtained from electrocardiographic recordings and electrical bioimpedance measurements from the thorax. These results suggest that cardiac and respiration activity offer better biomarkers for assessment of stress than speech, galvanic skin response or skin temperature when recorded with wearable biomedical measurement systems.

Revaluating US Land Ownership and Management in Order to Effectively Combat Soil Degradation

NASA Astrophysics Data System (ADS)

Drohan, Patrick

2017-04-01

Land privatization has resulted throughout history in: a variety of governance types; wealth imbalances; fluctuating degrees of food production; industrialization; and the privatization of intellectual ideas/property. USA government strategies to combat soil degradation have in large been reactive and driven by land privatization and the entrepreneurial nature of the US economy, especially agriculture. This has led to boom and bust cycles of agriculture and soil resilience. Further straining the capability to combat soil degradation are weaknesses in land management legislation due to separation of federal and state law and unfunded mandates. Last, the sheer size of the United States may be its greatest weakness in effectively developing a coherent national soil degradation policy. The recent failure of the European Soil Directive emphasizes the continual struggle between land privatization, food production, and the generation of wealth. We suggest several new strategies to combat USA soil degradation based on existing and new land management schemes, which have the potential to more effectively buffer the unpredictable future of increasing population and climate change.

"Heroes' invisible wounds of war:" constructions of posttraumatic stress disorder in the text of US federal legislation.

PubMed

Purtle, Jonathan

2016-01-01

Public policies contribute to the social construction of mental health problems. In this study, I use social constructivist theories of policy design and the methodology of ethnographic content analysis to qualitatively explore how posttraumatic stress disorder (PTSD) has been constructed as a problem in US federal legislation. I analyzed the text of 166 bills introduced between 1989 and 2009 and found that PTSD has been constructed as a problem unique to combat exposures and military populations. These constructions were produced through combat-related language and imagery (e.g., wounds, war, heroism), narratives describing PTSD as a military-specific phenomenon, and reinforced by the absence of PTSD in trauma-focused legislation targeting civilians. These constructions do not reflect the epidemiology of PTSD-the vast majority of people who develop the disorder have not experienced combat and many non-combat traumas (e.g., sexual assault) carry higher PTSD risk-and might constrain public and political discourse about the disorder and reify sociocultural barriers to the access of mental health services.

Land degradation, government subsidy, and smallholders' conservation decision: the case of the loess plateau in China.

PubMed

Shi, Min-Jun; Chen, Kevin

2004-12-01

Land degradation is one of the severe environmental problems in China. In order to combat land degradation, a soil conservation program was introduced since 2000 to reduce soil erosion by converting slope-cultivated land into forestry and pasture. This paper represents the first systematic attempt to investigate the impact of the soil conservation program on land degradation in the loess plateau. The results indicate that the soil conservation program to convert slope fields into forest or pasture is an effective way to combat soil erosion. However, a subsidy that is higher than profit of land use activity of slope fields before their conversion into forest and pasture is needed to encourage farmers to join the conservation program. A policy measure to encourage and assist farmers to develop sedentary livestock by using crops produced from fields as well as fodder and forage grass from the converted slope fields might contribute to combat soil erosion. Increase in off-farm job opportunities may encourage households to reduce cultivation in slope fields. That implies a policy measure to encourage rural urbanization might contribute to combat soil erosion.

Avalanches and power-law behaviour in lung inflation

NASA Astrophysics Data System (ADS)

Suki, Béla; Barabási, Albert-László; Hantos, Zoltán; Peták, Ferenc; Stanley, H. Eugene

1994-04-01

WHEN lungs are emptied during exhalation, peripheral airways close up1. For people with lung disease, they may not reopen for a significant portion of inhalation, impairing gas exchange2,3. A knowledge of the mechanisms that govern reinflation of collapsed regions of lungs is therefore central to the development of ventilation strategies for combating respiratory problems. Here we report measurements of the terminal airway resistance, Rt , during the opening of isolated dog lungs. When inflated by a constant flow, Rt decreases in discrete jumps. We find that the probability distribution of the sizes of the jumps and of the time intervals between them exhibit power-law behaviour over two decades. We develop a model of the inflation process in which 'avalanches' of airway openings are seen-with power-law distributions of both the size of avalanches and the time intervals between them-which agree quantitatively with those seen experimentally, and are reminiscent of the power-law behaviour observed for self-organized critical systems4. Thus power-law distributions, arising from avalanches associated with threshold phenomena propagating down a branching tree structure, appear to govern the recruitment of terminal airspaces.

Provider Perspectives on Evidence-Based HIV Prevention Interventions: Barriers and Facilitators to Implementation

PubMed Central

Dickson-Gomez, Julia

2011-01-01

Abstract Since the beginning of the HIV/AIDS epidemic, community-based organizations (CBOs) have been key players in combating this disease through grassroots prevention programs and close ties to at-risk populations. Increasingly, both funding agencies and public health institutions require that CBOs implement evidence-based HIV prevention interventions, most of which are researcher developed. However, after completing training for these evidence-based interventions (EBIs), agencies may either abandon plans to implement them or significantly modify the intervention. Based on 22 semistructured interviews with HIV prevention service providers, this article explores the barriers and facilitators to dissemination and implementation of EBIs included in the Centers for Disease Control and Prevention's (CDC) Diffusion of Effective Behavioral Interventions (DEBI) program. Results suggest that there is a tension between the need to implement interventions with fidelity and the lack of guidance on how to adapt the interventions for their constituencies and organizational contexts. Findings suggest the need for HIV prevention intervention development and dissemination that integrate community partners in all phases of research and dissemination. PMID:21323564

Opportunities and risks of the proposed FCTC protocol on illicit trade.

Liberman, Jonathan; Blecher, Evan; Carbajales, Alejandro Ramos; Burke, Fishburn

2011-11-01

Illicit trade in tobacco products presents a threat to public health because it undermines the use of tax and price policies, which are among the most effective mechanisms for reducing tobacco consumption. Parties to the WHO Framework Convention on Tobacco Control (FCTC) are in the final stages of negotiating a protocol aimed at strengthening international cooperation in the fight against illicit tobacco trade. While an effective multilateral response to illicit tobacco trade would make a significant contribution to global tobacco control, achieving this through the FCTC forum is challenging. First, while illicit tobacco trade is a health problem, the expertise, experience and capacity needed to combat illicit trade are not traditionally found in health agencies. The development of links with other agencies, both domestic and international, is critical to ensure both an effective response and an efficient use of limited governmental and non-governmental resources. Second, in many parts of the world, the tobacco industry cooperates closely with governments in the combating of illicit trade. This cooperation poses risks for tobacco control, particularly if relationships and norms of cooperation spill over into other areas of FCTC implementation. An examination of the industry's positioning suggests that it sees an opportunity to portray itself as 'legitimate' and 'responsible', a friend of governments, and a way to integrate itself into FCTC processes. This paper makes suggestions for moving forward in this challenging area towards ensuring that the approach taken actually reduces illicit tobacco trade, strengthens tobacco tax policies and does not operate to undermine the FCTC.

Combating healthcare corruption and fraud with improved global health governance

PubMed Central

2012-01-01

Corruption is a serious threat to global health outcomes, leading to financial waste and adverse health consequences. Yet, forms of corruption impacting global health are endemic worldwide in public and private sectors, and in developed and resource-poor settings alike. Allegations of misuse of funds and fraud in global health initiatives also threaten future investment. Current domestic and sectorial-level responses are fragmented and have been criticized as ineffective. In order to address this issue, we propose a global health governance framework calling for international recognition of “global health corruption” and development of a treaty protocol to combat this crucial issue.

2008-04-01

The Black Knight is a 12-ton, C-130 deployable Unmanned Ground Combat Vehicle (UGCV). It was developed to demonstrate how unmanned vehicles can be integrated into a mechanized military force to increase combat capability while protecting Soldiers in a full spectrum of battlefield scenarios. The Black Knight is used in military operational tests that allow Soldiers to develop the necessary techniques, tactics, and procedures to operate a large unmanned vehicle within a mechanized military force. It can be safely controlled by Soldiers from inside a manned fighting vehicle, such as the Bradley Fighting Vehicle. Black Knight control modes include path tracking, guarded teleoperation, and fully autonomous movement. Its state-of-the-art Autonomous Navigation Module (ANM) includes terrain-mapping sensors for route planning, terrain classification, and obstacle avoidance. In guarded teleoperation mode, the ANM data, together with automotive dials and gages, are used to generate video overlays that assist the operator for both day and night driving performance. Remote operation of various sensors also allows Soldiers to perform effective target location and tracking. This document covers Black Knight's system architecture and includes implementation overviews of the various operation modes. We conclude with lessons learned and development goals for the Black Knight UGCV.

Qualitative insights may demonstrate how combat medics (CM) deal with stressors and identify how resilience can potentially develop. Yet, qualitative research is scant in comparison to the many quantitative studies of health outcomes associated with military service. Semistructured qualitative interviews were used to collect personal narratives of US Army CMs who had previously served in Iraq or Afghanistan. Thematic analysis revealed three key driving forces for how resilience develops in the context of combat and war. The first was patriotism, which captures loyalty and full commitment to the military and its missions. The second was commitment to their family, reflecting the balance of responsibility to family of origin with the obligation one feels towards their military family. The last driving force was faith, or the drive to reach towards the transcendent to provide a moral compass and develop empathy in the face of difficult situations. An individual's commitment to country, military family and faith strengthens their resilience, and this can be used to inform future research efforts as well as current clinical practice. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Abductive networks applied to electronic combat

Montgomery, Gerard J.; Hess, Paul; Hwang, Jong S.

1990-08-01

A practical approach to dealing with combinatorial decision problems and uncertainties associated with electronic combat through the use of networks of high-level functional elements called abductive networks is presented. It describes the application of the Abductory Induction Mechanism (AIMTM) a supervised inductive learning tool for synthesizing polynomial abductive networks to the electronic combat problem domain. From databases of historical expert-generated or simulated combat engagements AIM can often induce compact and robust network models for making effective real-time electronic combat decisions despite significant uncertainties or a combinatorial explosion of possible situations. The feasibility of applying abductive networks to realize advanced combat decision aiding capabilities was demonstrated by applying AIM to a set of electronic combat simulations. The networks synthesized by AIM generated accurate assessments of the intent lethality and overall risk associated with a variety of simulated threats and produced reasonable estimates of the expected effectiveness of a group of electronic countermeasures for a large number of simulated combat scenarios. This paper presents the application of abductive networks to electronic combat summarizes the results of experiments performed using AIM discusses the benefits and limitations of applying abductive networks to electronic combat and indicates why abductive networks can often result in capabilities not attainable using alternative approaches. 1.

The role of vaccines in fighting antimicrobial resistance (AMR).

PubMed

Jansen, Kathrin U; Anderson, Annaliesa S

2018-05-22

The problem of antimicrobial resistance (AMR) and the associated morbidity and mortality due to antibiotic resistant bacterial pathogens is not new. However, AMR has been increasing at an alarming rate with appearances of diseases caused by bacteria exhibiting resistance to not just one but multiple classes of antibiotics. The World Health Organization (WHO) supported by governments, health ministries and health agencies has formulated global action plans to combat the rise in AMR, supporting a number of proven initiatives such as antimicrobial stewardship, investments in development of new classes of antibiotics, and educational programs designed to eliminate inappropriate antibiotic use. Vaccines as tools to reduce AMR have historically been under-recognized, yet the positive effect in reducing AMR has been well established. For example Haemophilus influenzae type B (Hib) as well as Streptococcus pneumoniae (pneumococcal) conjugate vaccines have impressive track records in not only preventing life threatening diseases caused by these bacteria, but also reducing antibiotic use and AMR. This paper will describe the drivers of antibiotic use and subsequent development of AMR; it will make the case how existing vaccines are already participating in combatting AMR, describe future prospects for the role of new vaccines in development to reduce AMR, and highlight challenges associated with future vaccine development to combat AMR.

A formulation and analysis of combat games

NASA Technical Reports Server (NTRS)

Heymann, M.; Ardema, M. D.; Rajan, N.

1985-01-01

Combat is formulated as a dynamical encounter between two opponents, each of whom has offensive capabilities and objectives. With each opponent is associated a target in the event space in which he endeavors to terminate the combat, thereby winning. If the combat terminates in both target sets simultaneously or in neither, a joint capture or a draw, respectively, is said to occur. Resolution of the encounter is formulated as a combat game; namely, as a pair of competing event-constrained differential games. If exactly one of the players can win, the optimal strategies are determined from a resulting constrained zero-sum differential game. Otherwise the optimal strategies are computed from a resulting non-zero-sum game. Since optimal combat strategies frequencies may not exist, approximate of delta-combat games are also formulated leading to approximate or delta-optimal strategies. To illustrate combat games, an example, called the turret game, is considered. This game may be thought of as a highly simplified model of air combat, yet it is sufficiently complex to exhibit a rich variety of combat behavior, much of which is not found in pursuit-evasion games.

The reliability and validity of a self-report measure of combat exposure are examined in a cohort of male-male twin pairs who served in the military during the Vietnam era. Test-retest reliability for a five-level ordinal index of combat exposure is assessed by use of 192 duplicate sets of responses. The chance-corrected proportion in agreement (as measured by the kappa coefficient) is .84. As a measure of criterion-related validity, the combat index is correlated with the award of combat-related military medals ascertained from the military records. The probability of receiving a Purple Heart, Bronze Star, Commendation Medal and Combat Infantry Badge is associated strongly with the combat exposure index. These results show that this simple index is a reliable and valid measure of combat exposure.

Evaluation of speech recognizers for use in advanced combat helicopter crew station research and development

NASA Technical Reports Server (NTRS)

Simpson, Carol A.

1990-01-01

The U.S. Army Crew Station Research and Development Facility uses vintage 1984 speech recognizers. An evaluation was performed of newer off-the-shelf speech recognition devices to determine whether newer technology performance and capabilities are substantially better than that of the Army's current speech recognizers. The Phonetic Discrimination (PD-100) Test was used to compare recognizer performance in two ambient noise conditions: quiet office and helicopter noise. Test tokens were spoken by males and females and in isolated-word and connected-work mode. Better overall recognition accuracy was obtained from the newer recognizers. Recognizer capabilities needed to support the development of human factors design requirements for speech command systems in advanced combat helicopters are listed.

UK Armed Forces (AF) personnel deployed to Afghanistan are frequently exposed to intense combat and yet little is known about the short-term mental health consequences of this exposure and the potential mitigating effects of military factors such as cohesion, morale, and leadership. To assess the possible modulating influence of cohesion, morale, and leadership on post-traumatic stress disorder (PTSD) symptoms and common mental disorders resulting from combat exposure among UK AF personnel deployed to Afghanistan, UK AF personnel, during their deployment to Afghanistan in 2010, completed a self-report survey about aspects of their current deployment, including perceived levels of cohesion, morale, leadership, combat exposure, and their mental health status. Outcomes were symptoms of common mental disorder and symptoms of PTSD. Combat exposure was associated with both PTSD symptoms and symptoms of common mental disorder. Of the 1,431 participants, 17.1% reported caseness levels of common mental disorder, and 2.7% were classified as probable PTSD cases. Greater self-reported levels of unit cohesion, morale, and perceived good leadership were all associated with lower levels of common mental disorder and PTSD. Greater levels of unit cohesion, morale, and good leadership may help to modulate the effects of combat exposure and the subsequent development of mental health problems among UK Armed Forces personnel deployed to Afghanistan. © 2012 Guilford Publications, Inc.

Introduction In response to a requirement for advanced trauma care nurses to provide combat tactical medical support, the antinarcotics arm of the Colombian National Police (CNP) requested the Colombian National Prehospital Care Association to develop a Combat Tactical Medicine Course (MEDTAC course). Objective To evaluate the effectiveness of this course in imparting knowledge and skills to the students. Methods We trained 374 combat nurses using the novel MEDTAC course. We evaluated students using pre-and postcourse performance with a 45-question examination. Field simulations and live tissue exercises were evaluated by instructors using a Likert scale with possible choices of 1 to 4. Interval estimation of proportions was calculated with a 95% confidence interval (95% CI). Differences in didactic test scores were assessed using a t-test at 0.05 level of statistical significance. Results Between March 2006 and July 2007, 374 combat nursing students of the CNP were trained. The difference between examination scores before and after the didactic part of the course was statistically significant (p < 0.01). After the practical session of the course, all participants (100%) demonstrated competency on final evaluation. Conclusions The MEDTAC course is an effective option improving the knowledge and skills of combat nurses serving in the CNP. MEDTAC represents a customized approach for military trauma care training in Colombia. This course is an example of specialized training available for groups that operate in austere environments with limited resources. PMID:19947877

Self-Compassion as a Prospective Predictor of PTSD Symptom Severity Among Trauma-Exposed U.S. Iraq and Afghanistan War Veterans

U. S. combat veterans of the Iraq and Afghanistan wars have elevated rates of posttraumatic stress disorder (PTSD) compared to the general population. Self-compassion, characterized by self-kindness, a sense of common humanity when faced with suffering, and mindful awareness of suffering, is a potentially modifiable factor implicated in the development and maintenance of PTSD. We examined the concurrent and prospective relationship between self-compassion and PTSD symptom severity after accounting for level of combat exposure and baseline PTSD severity. Participants at baseline assessment were 115 Iraq and Afghanistan war veterans exposed to 1 or more traumatic events during deployment (n = 101 at follow-up). PTSD symptoms were assessed using the Clinician Administered PTSD Scale for DSM-IV at baseline and 12 months. Self-compassion and combat exposure were assessed at baseline via self-report. Self-compassion was associated with baseline PTSD symptoms after accounting for combat exposure (β = −.59; p < .001; ΔR2 = .34; f2 = .67; large effect) and predicted 12-month PTSD symptom severity after accounting for combat exposure and baseline PTSD severity (β = −.24; p = .008; ΔR2 = .03; f2 = .08; small effect). Findings suggest that interventions that increase self-compassion may be beneficial for treating chronic PTSD symptoms among some Iraq and Afghanistan war veterans. PMID:25808565

Martindale, Sarah L; Morissette, Sandra B; Rowland, Jared A; Dolan, Sara L

2017-01-01

The purpose of this study was to determine how sleep quality affects cognitive functioning in returning combat veterans after accounting for effects of combat exposure, posttraumatic stress disorder (PTSD), and mild traumatic brain injury (mTBI) history. This was a cross-sectional assessment study evaluating combat exposure, PTSD, mTBI history, sleep quality, and neuropsychological functioning. One hundred and nine eligible male Iraq/Afghanistan combat veterans completed an assessment consisting of a structured clinical interview, neuropsychological battery, and self-report measures. Using partial least squares structural equation modeling, combat experiences and mTBI history were not directly associated with sleep quality. PTSD was directly associated with sleep quality, which contributed to deficits in neuropsychological functioning independently of and in addition to combat experiences, PTSD, and mTBI history. Combat experiences and PTSD were differentially associated with motor speed. Sleep affected cognitive function independently of combat experiences, PTSD, and mTBI history. Sleep quality also contributed to cognitive deficits beyond effects of PTSD. An evaluation of sleep quality may be a useful point of clinical intervention in combat veterans with cognitive complaints. Improving sleep quality could alleviate cognitive complaints, improving veterans' ability to engage in treatment. (PsycINFO Database Record (c) 2016 APA, all rights reserved).

Reproductive cloning and a (kind of) genetic fallacy.

PubMed

Levy, Neil; Lotz, Mianna

2005-06-01

Many people now believe that human reproductive cloning--once sufficiently safe and effective--should be permitted on the grounds that it will allow the otherwise infertile to have children that are biologically closely related to them. However, though it is widely believed that the possession of a close genetic link to our children is morally significant and valuable, we argue that such a view is erroneous. Moreover, the claim that the genetic link is valuable is pernicious; it tends to give rise to highly undesirable consequences, and therefore should be combated rather than pandered to. The emphasis on the genetic is unwarranted and unfortunate; rather than giving us moral reason to support reproductive cloning in the case of infertility, the fact that cloning requests are likely to be motivated by the genetic argument gives us reason to oppose its availability.

Active drug efflux constitutes an important mechanism of antibiotic and multidrug resistance in bacteria. Understanding the distribution, expression, and physiological functions of multidrug efflux pumps, especially under physiologically and clinically relevant conditions of the pathogens, is the key to combat drug resistance. In animal hosts, most wounded, infected and inflamed tissues display low oxygen tensions. In this article, we summarize research development on multidrug efflux pumps in the medicinally relevant microaerobic and anaerobic pathogens and their implications in the effort to combat drug-resistant infections.

A formulation and analysis of combat games

NASA Technical Reports Server (NTRS)

Heymann, M.; Ardema, M. D.; Rajan, N.

1984-01-01

Combat which is formulated as a dynamical encounter between two opponents, each of whom has offensive capabilities and objectives is outlined. A target set is associated with each opponent in the event space in which he endeavors to terminate the combat, thereby winning. If the combat terminates in both target sets simultaneously, or in neither, a joint capture or a draw, respectively, occurs. Resolution of the encounter is formulated as a combat game; as a pair of competing event constrained differential games. If exactly one of the players can win, the optimal strategies are determined from a resulting constrained zero sum differential game. Otherwise the optimal strategies are computed from a resulting nonzero sum game. Since optimal combat strategies may frequently not exist, approximate or delta combat games are also formulated leading to approximate or delta optimal strategies. The turret game is used to illustrate combat games. This game is sufficiently complex to exhibit a rich variety of combat behavior, much of which is not found in pursuit evasion games.

U.S. casualties have developed multidrug-resistant (MDR) bacterial infections. A surveillance project to evaluate U.S. military patients for the presence of MDR pathogens from wounding through the first 30 days of care in the military healthcare system (MHS) was performed. U.S. military patients admitted to a single combat support hospital in Iraq during June-July of 2007 had screening swabs obtained for the detection of MDR bacteria and a subsequent retrospective electronic medical records review for presence of colonization or infection in the subsequent 30 days. Screening of 74 U.S. military patients in Iraq found one colonized with methicillin-resistant Staphylococcus aureus. Fifty-six patients of these were screened for Acinetobacter in Germany and one found colonized. Of patients evacuated to the U.S., 9 developed infections. Carefully obtained screening cultures immediately after injury combined with look-back monitoring supports the role of nosocomial transmission. Consistent infection control strategies are needed for the entire MHS.

Stigma, American military personnel and mental health care: challenges from Iraq and Afghanistan.

PubMed

Schreiber, Michael; McEnany, Geoffry Phillips

2015-02-01

Since 2001, more than 2.5 million United States military personnel have been deployed for combat. Over one million have served multiple deployments. Combat generally involved repeated exposure to highly traumatic events. Personnel were also victims of military sexual trauma (MST), a major risk factor for psychiatric illness. Most survivors do not seek or receive mental health care. Stigma is one of the main barriers to that care. To explore the impact of stigma on personnel with psychiatric illness, and suggest some innovative ways to potentially reduce stigma and improve care. Cinahl and PubMed databases were searched from 2001 to 2014. Anonymity, the use of non-stigmatizing language, peer-to-peer, and stigma-reduction programs help military personnel receive mental health care. Technology offers the opportunity for effective and appropriate education and treatment. Although stigma is formidable, several innovative services are available or being developed for military victims of trauma. Commitment of resources for program development and further research to explore which interventions offer the best clinical outcomes are needed to increase efforts to combat stigma and ensure quality care.

Combat veterans: impressions of an analytic observer in a non-analytic setting.

Stein, Herbert H

2007-01-01

The hallmark presentation of combat trauma-nightmares, waking hallucinations, intrusive traumatic memories, and extreme affective reactions to environmental triggers-may best be conceptualized as part of an adaptive mechanism intended to protect the individual against a repetition of trauma. Combat veterans continuously must cope with the extreme affects that combat induced. Fear, rage, guilt, and grief predominate. Their mental and emotional life is complicated by a conscience split between war zone and civilian morality and by the special group dynamics of combat. Optimal clinical understanding of combat-related trauma, whether in a psychoanalytic or general mental health setting, requires an awareness of the interaction of the personal dynamics of each individual with the specific characteristics of their combat situation.

Situation assessment in the Paladin tactical decision generation system

NASA Technical Reports Server (NTRS)

Mcmanus, John W.; Chappell, Alan R.; Arbuckle, P. Douglas

1992-01-01

Paladin is a real-time tactical decision generator for air combat engagements. Paladin uses specialized knowledge-based systems and other Artificial Intelligence (AI) programming techniques to address the modern air combat environment and agile aircraft in a clear and concise manner. Paladin is designed to provide insight into both the tactical benefits and the costs of enhanced agility. The system was developed using the Lisp programming language on a specialized AI workstation. Paladin utilizes a set of air combat rules, an active throttle controller, and a situation assessment module that have been implemented as a set of highly specialized knowledge-based systems. The situation assessment module was developed to determine the tactical mode of operation (aggressive, defensive, neutral, evasive, or disengagement) used by Paladin at each decision point in the air combat engagement. Paladin uses the situation assessment module; the situationally dependent modes of operation to more accurately represent the complex decision-making process of human pilots. This allows Paladin to adapt its tactics to the current situation and improves system performance. Discussed here are the details of Paladin's situation assessment and modes of operation. The results of simulation testing showing the error introduced into the situation assessment module due to estimation errors in positional and geometric data for the opponent aircraft are presented. Implementation issues for real-time performance are discussed and several solutions are presented, including Paladin's use of an inference engine designed for real-time execution.

Networked sensors for the combat forces

NASA Astrophysics Data System (ADS)

Klager, Gene

2004-11-01

Real-time and detailed information is critical to the success of ground combat forces. Current manned reconnaissance, surveillance, and target acquisition (RSTA) capabilities are not sufficient to cover battlefield intelligence gaps, provide Beyond-Line-of-Sight (BLOS) targeting, and the ambush avoidance information necessary for combat forces operating in hostile situations, complex terrain, and conducting military operations in urban terrain. This paper describes a current US Army program developing advanced networked unmanned/unattended sensor systems to survey these gaps and provide the Commander with real-time, pertinent information. Networked Sensors for the Combat Forces plans to develop and demonstrate a new generation of low cost distributed unmanned sensor systems organic to the RSTA Element. Networked unmanned sensors will provide remote monitoring of gaps, will increase a unit"s area of coverage, and will provide the commander organic assets to complete his Battlefield Situational Awareness (BSA) picture for direct and indirect fire weapons, early warning, and threat avoidance. Current efforts include developing sensor packages for unmanned ground vehicles, small unmanned aerial vehicles, and unattended ground sensors using advanced sensor technologies. These sensors will be integrated with robust networked communications and Battle Command tools for mission planning, intelligence "reachback", and sensor data management. The network architecture design is based on a model that identifies a three-part modular design: 1) standardized sensor message protocols, 2) Sensor Data Management, and 3) Service Oriented Architecture. This simple model provides maximum flexibility for data exchange, information management and distribution. Products include: Sensor suites optimized for unmanned platforms, stationary and mobile versions of the Sensor Data Management Center, Battle Command planning tools, networked communications, and sensor management software. Details of these products and recent test results will be presented.

The aim of this study was to investigate the effects of caffeine on reaction time during a specific taekwondo task and athletic performance during a simulated taekwondo contest. Ten taekwondo athletes ingested either 5 mg·kg−1 body mass caffeine or placebo and performed two combats (spaced apart by 20 min). The reaction-time test (five kicks “Bandal Tchagui”) was performed immediately prior to the first combat and immediately after the first and second combats. Caffeine improved reaction time (from 0.42 ± 0.05 to 0.37 ± 0.07 s) only prior to the first combat (P = 0.004). During the first combat, break times during the first two rounds were shorter in caffeine ingestion, followed by higher plasma lactate concentrations compared with placebo (P = 0.029 and 0.014, respectively). During the second combat, skipping-time was reduced, and relative attack times and attack/skipping ratio was increased following ingestion of caffeine during the first two rounds (all P < 0.05). Caffeine resulted in no change in combat intensity parameters between the first and second combat (all P > 0.05), but combat intensity was decreased following placebo (all P < 0.05). In conclusion, caffeine reduced reaction time in non-fatigued conditions and delayed fatigue during successive taekwondo combats. PMID:24518826

Motion sickness: Can it be controlled

NASA Technical Reports Server (NTRS)

Carnes, David

1988-01-01

NASA is one of the few research centers concerned with motion sickness. Since the physiology of man has been developed in the one-gravity field Earth, the changes experienced by man in space are unique, and often result in symptoms that resemble motion sickness on Earth. NASA is concerned with motion sickness because it is very uncomfortable for the astronauts. Another concern of NASA is the possibility of a motion sickness astronaut regurgitating while he or she is sealed in an airtight space suit. This could be fatal. Motivated by these reasons, NASA spent thousands of dollars in research and development for a drug or technique for combating motion sickness. Several different treatments were developed for this disorder. Three of the most effective ways of combatting motion sickness are discussed.

Critical evaluation of all aspects of combat casualty care, including mortality, with a special focus on the incidence and causes of potentially preventable deaths among US combat fatalities, is central to identifying gaps in knowledge, training, equipment, and execution of battlefield trauma care. The impetus to produce this analysis was to develop a comprehensive perspective of battlefield death, concentrating on deaths that occurred in the pre-medical treatment facility (pre-MTF) environment. The Armed Forces Medical Examiner Service Mortality Surveillance Division was used to identify Operation Iraqi Freedom and Operation Enduring Freedom combat casualties from October 2001 to June 2011 who died from injury in the deployed environment. The autopsy records, perimortem records, photographs on file, and Mortality Trauma Registry of the Armed Forces Medical Examiner Service were used to compile mechanism of injury, cause of injury, medical intervention performed, Abbreviated Injury Scale (AIS) score, and Injury Severity Score (ISS) on all lethal injuries. All data were used by the expert panel for the conduct of the potential for injury survivability assessment of this study. For the study interval between October 2001 and June 2011, 4,596 battlefield fatalities were reviewed and analyzed. The stratification of mortality demonstrated that 87.3% of all injury mortality occurred in the pre-MTF environment. Of the pre-MTF deaths, 75.7% (n = 3,040) were classified as nonsurvivable, and 24.3% (n = 976) were deemed potentially survivable (PS). The injury/physiologic focus of PS acute mortality was largely associated with hemorrhage (90.9%). The site of lethal hemorrhage was truncal (67.3%), followed by junctional (19.2%) and peripheral-extremity (13.5%) hemorrhage. Most battlefield casualties died of their injuries before ever reaching a surgeon. As most pre-MTF deaths are nonsurvivable, mitigation strategies to impact outcomes in this population need to be directed toward injury prevention. To significantly impact the outcome of combat casualties with PS injury, strategies must be developed to mitigate hemorrhage and optimize airway management or reduce the time interval between the battlefield point of injury and surgical intervention.Understanding battlefield mortality is a vital component of the military trauma system. Emphasis on this analysis should be placed on trauma system optimization, evidence-based improvements in Tactical Combat Casualty Care guidelines, data-driven research, and development to remediate gaps in care and relevant training and equipment enhancements that will increase the survivability of the fighting force.

Modeling the effectiveness of oil combating from an ecological perspective--a Bayesian network for the Gulf of Finland; the Baltic Sea.

PubMed

Helle, Inari; Lecklin, Tiina; Jolma, Ari; Kuikka, Sakari

2011-01-15

Maritime traffic poses a major threat to marine ecosystems in the form of oil spills. The Gulf of Finland, the easternmost part of the Baltic Sea, has witnessed a rapid increase in oil transportation during the last 15 years. Should a spill occur, the negative ecological impacts may be reduced by oil combating, the effectiveness of which is, however, strongly dependent on prevailing environmental conditions and available technical resources. This poses increased uncertainty related to ecological consequences of future spills. We developed a probabilistic Bayesian network model that can be used to assess the effectiveness of different oil combating strategies in minimizing the negative effects of oil on six species living in the Gulf of Finland. The model can be used for creating different accident scenarios and assessing the performance of various oil combating actions under uncertainty, which enables its use as a supportive tool in decision-making. While the model is confined to the western Gulf of Finland, the methodology is adaptable to other marine areas facing similar risks and challenges related to oil spills.

The effects of elevated hearing thresholds on performance in a paintball simulation of individual dismounted combat.

PubMed

Sheffield, Benjamin; Brungart, Douglas; Tufts, Jennifer; Ness, James

2017-01-01

To examine the relationship between hearing acuity and operational performance in simulated dismounted combat. Individuals wearing hearing loss simulation systems competed in a paintball-based exercise where the objective was to be the last player remaining. Four hearing loss profiles were tested in each round (no hearing loss, mild, moderate and severe) and four rounds were played to make up a match. This allowed counterbalancing of simulated hearing loss across participants. Forty-three participants across two data collection sites (Fort Detrick, Maryland and the United States Military Academy, New York). All participants self-reported normal hearing except for two who reported mild hearing loss. Impaired hearing had a greater impact on the offensive capabilities of participants than it did on their "survival", likely due to the tendency for individuals with simulated impairment to adopt a more conservative behavioural strategy than those with normal hearing. These preliminary results provide valuable insights into the impact of impaired hearing on combat effectiveness, with implications for the development of improved auditory fitness-for-duty standards, the establishment of performance requirements for hearing protection technologies, and the refinement of strategies to train military personnel on how to use hearing protection in combat environments.

Assured communications and combat resiliency: the relationship between effective national communications and combat efficiency

2009-05-01

Combat resiliency is the ability of a commander to prosecute, control, and consolidate his/her's sphere of influence in adverse and changing conditions. To support this, an infrastructure must exist that allows the commander to view the world in varying degrees of granularity with sufficient levels of detail to permit confidence estimates to be levied against decisions and course of actions. An infrastructure such as this will include the ability to effectively communicate context and relevance within and across the battle space. To achieve this will require careful thought, planning, and understanding of a network and its capacity limitations in post-event command and control. Relevance and impact on any existing infrastructure must be fully understood prior to deployment to exploit the system's full capacity and capabilities. In this view, the combat communication network is considered an integral part of or National communication network and infrastructure. This paper will describe an analytical tool set developed at ORNL and RNI incorporating complexity theory, advanced communications modeling, simulation, and visualization technologies that could be used as a pre-planning tool or post event reasoning application to support response and containment.

Limbic white matter pathways link emotion, cognition, and behavior and are potentially malleable to the influences of traumatic events throughout development. However, the impact of interactions between childhood and later life trauma on limbic white matter pathways has yet to be examined. Here, we examined whether childhood maltreatment moderated the effect of combat exposure on diffusion tensor imaging measures within a sample of military veterans (N = 28). We examined five limbic tracts of interest: two components of the cingulum (cingulum, cingulate gyrus, and cingulum hippocampus [CGH]), the uncinate fasciculus, the fornix/stria terminalis, and the anterior limb of the internal capsule. Using effect sizes, clinically meaningful moderator effects were found only within the CGH. Greater combat exposure was associated with decreased CGH fractional anisotropy (overall structural integrity) and increased CGH radial diffusivity (perpendicular water diffusivity) among individuals with more severe childhood maltreatment. Our findings provide preliminary evidence of the moderating effect of childhood maltreatment on the relationship between combat exposure and CGH structural integrity. These differences in CGH structural integrity could have maladaptive implications for emotion and memory, as well as provide a potential mechanism by which childhood maltreatment induces vulnerability to later life trauma exposure.

Military personnel deployed in support of combat operations are at significantly higher risk for mental health problems. However, much of what we know about combat-related mental health comes from postdeployment assessments. This study describes the mental health of 1,336 treatment-seeking deployed U.S. military personnel and interventions recommended by military mental health providers in Iraq from January 2006 to January 2007. Cases were primarily young enlisted men, most of whom were on their first combat deployment. Marines made up the majority of the cases (60%), but there were also large numbers of Army and Navy personnel. The most common psychiatric diagnoses were anxiety disorders (31%, including 11% with posttraumatic stress disorder), followed by adjustment (27%) and mood disorders (25%, including 22% with depression). Medication was the most commonly prescribed treatment for patients with psychiatric diagnoses but was often combined with recommendations for psychotherapy/counseling and/or behavioral modifications. The findings illustrate the distribution of mental health conditions seen among treatment-seeking troops while actively serving in a combat environment and the interventions recommended for them. Further examination of postdeployment health outcomes may help to facilitate the development of more effective acute intervention strategies in theater.

Individual differences in cognitive processes and coping behaviors play a role in the development and maintenance of posttraumatic stress disorder (PTSD). Given the large numbers of combat-exposed service members returning from the Operation Enduring Freedom (OEF), Operation Iraqi Freedom (OIF), and Operation New Dawn (OND) conflicts, exploring individual differences in cognitive-affective processes is important for informing our understanding of PTSD etiology and early intervention in military samples. The present study examined the unique main and interactive effects of negative posttrauma cognitions (i.e., negative beliefs about self [NS], the world [NW], and self-blame [SB]) and coping strategies (i.e., positive behavioral, positive cognitive, avoidant coping, and social and emotional coping) on PTSD diagnosis within 155 ( M age = 30.7, SD = 4.48) OEF/OIF/OND combat trauma-exposed veterans recruited from an ongoing study examining the effects of combat trauma and stress reactivity. In the final, stepwise logistic regression analysis, avoidant coping, but no other coping strategy, was significantly positively related to PTSD diagnosis in the initial step. Higher levels of NS, but not NW, were significantly associated with having a PTSD diagnosis, while SB was associated with decreased likelihood of PTSD, above and beyond coping strategies. A significant interaction effect was found between NS and positive cognitive coping, such that greater positive cognitive coping weakened the relationship between NS and PTSD. Examining and addressing coping behaviors and negative thoughts of self jointly may benefit assessment and intervention approaches in a combat-trauma population.

This article explores the psychophysiological metrics during expert and novice performances in marksmanship, combat deadly force judgment and decision making (DFJDM), and interactions of teams. Electroencephalography (EEG) and electrocardiography (ECG) are used to characterize the psychophysiological profiles within all categories. Closed-loop biofeedback was administered to accelerate learning during marksmanship training in which the results show a difference in groups that received feedback compared with the control. During known distance marksmanship and DFJDM scenarios, experts show superior ability to control physiology to meet the demands of the task. Expertise in teaming scenarios is characterized by higher levels of cohesiveness than those seen in novices.

Mixed martial arts: injury patterns and issues for the ringside physician.

Seidenberg, Peter H

2011-01-01

Mixed martial arts (MMA) is a fast-growing combat sport. There are limited studies investigating MMA's injury incidence. However, from the data available, closed head injuries and lacerations commonly are experienced by competitors. Sanctioned events require the presence of ringside physicians, who should be well versed in handling these types of injuries. Additionally, sports-medicine providers should have an appropriately equipped medical bag, and before providing coverage, they need to coordinate with emergency medical personnel in order to more efficiently deliver care if urgent situations arise. More research is needed on injury incidence and prevention in MAA.

Lubin, Gadi; Barash, Igor; Levinson, Daphna

2016-01-01

To compare the mental health status of those who participated in combat related activities during their service with that of soldiers whose army service did not include combat related activities Method: A representative sample extracted from the National Population Register of non-institutionalized residents aged 21 or older of Israel was used in this crosssectional survey. Data on mental health disorders, sociodemographic background and army service were collected using face-to-face computer-assisted interviews. Combat experience per se was not associated with lifetime diagnosis of PTSD. Former combat soldiers had significantly lower lifetime prevalence and 12 months prevalence of any mood or anxiety disorders including PTSD. This work is in line with previous literature showing that combat exposure, as such, has limited contribution to lifetime PTSD in some groups of veterans. The inverse relationship between combat exposure and PTSD might be explained by the selection of potential combatants among all recruits and by the heightened preparedness to military life stressors.

Posttraumatic stress disorder is often diagnosed with other mental health problems, particularly depression. Although PTSD comorbidity has been associated with more severe and chronic symptomology, relationships among commonly co-occurring disorders are not well understood. The purpose of this study was to review the literature regarding the development of depression comorbid with combat-related PTSD among military personnel. We summarize results of commonly tested hypotheses about the etiology of PTSD and depression comorbidity, including (1) causal hypotheses, (2) common factor hypotheses, and (3) potential confounds. Evidence suggests that PTSD may be a causal risk factor for subsequent depression; however, associations are likely complex, involving bidirectional causality, common risk factors, and common vulnerabilities. The unique nature of PTSD-depression comorbidity in the context of military deployment and combat exposure is emphasized. Implications of our results for clinical practice and future research are discussed. Published by Elsevier Ltd.

Mental health care use by soldiers conducting counterinsurgency operations.

2012-05-01

Counterinsurgency (COIN) has become the cornerstone of the military's strategy to combat terrorist threats. COIN operations are complex and often expose soldiers to unfamiliar stressors as they fight the enemy while developing and maintaining rapport with the local populace. Utilizing a retrospective record review protocol, we examined 282 mental health files of soldiers assigned to a brigade combat team that operated from a large forward operating base in Iraq during the counterinsurgency campaign. Most reported sleep disturbance, depression, anxiety, irritability, and conflict with supervisors related to either operational stress, exposure to direct combat, or home front concerns. Most received brief individual supportive therapy or attended solution-focused group counseling emphasizing life skills training, post-traumatic stress treatment, women's support, or relationship skills. Psychopharmacologic treatment was an essential adjunct to the counseling program. Results indicate that supporting a COIN deployment requires a comprehensive mental health program that can respond to a wide range of mental health problems.

Leading a deployed combat healthcare system is a very complex task and requires a command and control structure that is a unique blend of technical and tactical expertise to efficaciously deliver world-class medical care to America's sons and daughters. The medical task force in Iraq has successfully managed the transformation of the medical footprint from a tactically arrayed set of disparate medical units to a nascent integrated healthcare system with many features similar to the best healthcare systems in the United States. The American public demands, and Soldiers, Marines, Sailors, Airmen, and Coast Guardsmen deserve US quality medical care, whether they are being treated at a military medical center in the US, or a US medical facility in Iraq. This article presents an overview of the 62nd Medical Brigade's development of the combat healthcare support system during its tenure leading the US medical task force in Iraq.

War-fighters exposed to combat are at high risk for developing posttraumatic stress disorder (PTSD), a complex and challenging condition to treat. Cognitive behavioral therapies (CBT) have been empirically validated as effective treatments for PTSD resulting from sexual assault, vehicular accidents, and disasters. Exposure, imaginal or in vivo, to the traumatic event is a central component of successful CBT treatment. Early studies indicate that CBT with brief virtual reality exposure (VRE) is beneficial in treating PTSD. The case study examined the effectiveness of brief VRE in treating combat-related PTSD.

2001-08-01

Torpedoes and other Unmanned Undersea Vehicles (UUV) are employed by submarines and surface combatants, as well as aircraft, for undersea warfare. These vehicles are autonomous devices whose guidance systems rival the complexity of the most sophisticated air combat missiles. The tactical environment for undersea warfare is a difficult one in terms of target detection,k classification, and pursuit because of the physics of underwater sounds. Both hardware-in-the-loop and all-digital simulations have become vital tools in developing and evaluating undersea weapon and vehicle guidance performance in the undersea environment.

Effects of training and simulated combat stress on leg tourniquet application accuracy, time, and effectiveness.

Schreckengaust, Richard; Littlejohn, Lanny; Zarow, Gregory J

2014-02-01

The lower extremity tourniquet failure rate remains significantly higher in combat than in preclinical testing, so we hypothesized that tourniquet placement accuracy, speed, and effectiveness would improve during training and decline during simulated combat. Navy Hospital Corpsman (N = 89), enrolled in a Tactical Combat Casualty Care training course in preparation for deployment, applied Combat Application Tourniquet (CAT) and the Special Operations Forces Tactical Tourniquet (SOFT-T) on day 1 and day 4 of classroom training, then under simulated combat, wherein participants ran an obstacle course to apply a tourniquet while wearing full body armor and avoiding simulated small arms fire (paint balls). Application time and pulse elimination effectiveness improved day 1 to day 4 (p < 0.005). Under simulated combat, application time slowed significantly (p < 0.001), whereas accuracy and effectiveness declined slightly. Pulse elimination was poor for CAT (25% failure) and SOFT-T (60% failure) even in classroom conditions following training. CAT was more quickly applied (p < 0.005) and more effective (p < 0.002) than SOFT-T. Training fostered fast and effective application of leg tourniquets while performance declined under simulated combat. The inherent efficacy of tourniquet products contributes to high failure rates under combat conditions, pointing to the need for superior tourniquets and for rigorous deployment preparation training in simulated combat scenarios.

Objective To examine the circumstances surrounding weapon injury and combatant status of those injured by weapons. Design Prospective cohort study. Setting Northwestern Cambodia after departure of United Nations peacekeeping force. Subjects 863 people admitted to hospital for weapon injuries over 12 months. Main outcome measures Annual incidence of weapon injury by time period; proportions of injuries inflicted as a result of interfactional combat (combat injuries) and outside such combat (non-combat injuries) by combatant status and weapon type. Results The annual incidence of weapon injuries was higher than the rate observed before the peacekeeping operation. 30% of weapon injuries occurred in contexts other than interfactional combat. Most commonly these were firearm injuries inflicted intentionally on civilians. Civilians accounted for 71% of those with non-combat injuries, 42% of those with combat related injuries, and 51% of those with weapon injuries of either type. Conclusions The incidence of weapon injuries remained high when the disarmament component of a peacekeeping operation achieved only limited success. Furthermore, injuries occurring outside the context of interfactional combat accounted for a substantial proportion of all weapon injuries, were experienced disproportionately by civilians, and were most likely to entail the intentional use of a firearm against a civilian. Key messagesThe study took place in Cambodia after a United Nations peacekeeping operation that achieved only limited success in disarmamentA substantial proportion of weapon injuries was inflicted in contexts unrelated to interfactional combatThese injuries were most commonly firearm injuries inflicted intentionally on civiliansWidespread availability of weapons can facilitate social violence PMID:10445922

The Spitzkoppe Community Campsite in western Namibia lies in an area with very limited water resources. Water scarcity places a constraint on community income generation and development opportunities. The existing water resources are overexploited and to ensure future water security, the community must take sustainable water management into consideration in their daily lives and business ventures, including tourism. This has been successfully achieved at the Spitzkoppe Community Campsite through a combination of high community motivation, organisation and action, the involvement of researchers and trainers in water resource management and support from developers. The most appropriate water management solutions were found through ongoing practical testing of different strategies and technologies over two years. This paper presents a case study of a community-based tourist camp at Spitzkoppe and traces the community's progress towards developing an alternative way to combat desertification and a potentially lucrative tourist business.

2007-01-01

Objectives To assess the distribution and risk factors of depleted uranium uptake in military personnel who had taken part in the invasion of Iraq in 2003. Methods Sector field inductively coupled plasma-mass spectrometry (SF-ICP-MS) was used to determine the uranium concentration and 238U/235U isotopic ratio in spot urine samples. The authors collected urine samples from four groups identified a priori as having different potential for exposure to depleted uranium. These groups were: combat personnel (n = 199); non-combat personnel (n = 96); medical personnel (n = 22); and “clean-up” personnel (n = 24) who had been involved in the maintenance, repair or clearance of potentially contaminated vehicles in Iraq. A short questionnaire was used to ascertain individual experience of circumstances in which depleted uranium exposure might have occurred. Results There was no statistically significant difference in the 238U/235U ratio between groups. Mean ratios by group varied from 138.0 (95% CI 137.3 to 138.7) for clean-up personnel to 138.2 (95% CI 138.0 to 138.5) for combat personnel, and were close to the ratio of 137.9 for natural uranium. The two highest individual ratios (146.9 and 147.7) were retested using more accurate, multiple collector inductively coupled plasma-mass spectrometry (MC-ICP-MS) and found to be within measurement of error of that for natural uranium. There were no significant differences in isotope ratio between participants according to self-reported circumstances of potential depleted uranium exposure. Conclusions Based on measurements using a SF-ICP-MS apparatus, this study provides reassurance following concern for potential widespread depleted uranium uptake in the UK military. The rare occurrence of elevated ratios may reflect the limits of accuracy of the SF-ICP-MS apparatus and not a real increase from the natural proportions of the isotopes. Any uptake of depleted uranium among participants in this study sample would be very unlikely to have any implications for health. PMID:17609224

The stratification of military service and combat exposure, 1934–1994*

PubMed Central

MacLean, Alair

2010-01-01

Previous research has suggested that men who were exposed to combat during wartime differed from those who were not. Yet little is known about how selection into combat has changed over time. This paper estimates sequential logistic models using data from the Panel Study of Income Dynamics to examine the stratification of military service and combat exposure in the US during the last six decades of the twentieth century. It tests potentially overlapping hypotheses drawn from two competing theories, class bias and dual selection. It also tests a hypothesis, drawn from the life course perspective, that the processes by which people came to see combat have changed historically. The findings show that human capital, institutional screening, and class bias all determined who saw combat. They also show that, net of historical change in the odds of service and combat, the impact of only one background characteristic, race, changed over time. PMID:21113325

2012-05-01

To provide a better understanding of any associations between Disarmament, Demobilization, and Reintegration, previous head injury, and mental health symptoms among former combatants in Liberia. A cluster-sampled national survey of the adult household-based Liberian population. Former combatants with reported head injury were more likely to experience major depressive disorder symptoms, suicidal ideation and attempts, and current substance abuse. Former combatants with head injury are 2.83 times more likely to have major depressive disorder symptoms, and those with suspected traumatic brain injury are five times more likely to have post-traumatic stress disorder. The poor mental health of former combatants in Liberia, both child and adult, might be mitigated if Disarmament, Demobilization, and Reintegration programming assessed participants for head trauma and traumatic brain injury using simple screening methods. The specific health and mental health needs of ex-combatants--a highly vulnerable group--will need to be addressed by Liberia. If left untreated, ex-combatants with high rates of suicidal ideation and post-traumatic stress disorder might be susceptible to re-recruitment into new conflicts in the region.

2015-01-01

Research increasingly demonstrates that trauma exposure can have cumulative effects, yet much remains to be learned about effects of cumulative trauma, particularly regarding longer term adjustment. One such trauma, combat exposure, is insufficiently understood, especially for women, who are increasingly engaged in professional combat activities. The study comprised a cross-sectional survey assessing multiple aspects of current well-being in women approximately 25 years after their service in Vietnam during the Vietnam War. Participants were 1374 women (78% military and 22% nonmilitary; mean age = 59.7). This study investigated the relations between three separate categories of trauma exposure (childhood, adulthood, and combat) and well-being and examined whether perceived social support at return from Vietnam moderated the association between combat exposure and well-being. While both childhood and adulthood trauma exposure related to midlife well-being, combat exposure still uniquely predicted outcomes. Further, postdeployment perceived social support moderated the association of combat and well-being: recollected higher perceived social support at homecoming buffered participants from the links between combat exposure and well-being. These results may have important implications for interventions to reduce the impact of traumatic experiences, particularly in light of the increasing exposure of women to direct combat events.

The 274th Forward Surgical Team (FST) was deployed in support of Operation Enduring Freedom from October 14, 2001 to May 8, 2002. During this period, the FST was asked to perform many nondoctrinal missions. The FST was tasked with functioning as a mini-combat support hospital during the earlier phases of Operation Enduring Freedom, performing in-flight surgical procedures and resuscitation of combat wounded, conducting split operations with surgical coverage of both Karshi and Khanabad, Uzbekistan, and Bagram, Afghanistan, and leading the multinational medical coalition assembled for Operation Anaconda and other combat operations staged from Bagram. Overall, the 274th FST took care of approximately 90% of U.S. combat casualties during this period and treated a total of 221 combat casualties. The FST treated 103 total surgical cases, including 73 with combat wounds. At the time, this experience with combat casualties and the surgical care of combat wounds was the largest since the Persian Gulf War. More importantly, this account describes the flow, frequency, and type of combat casualties seen in a low-intensity conflict like that being waged currently in Afghanistan. It is hoped that this depiction will aid in the preparation, equipping, and overall utilization of surgical assets in similar future conflicts.

A High-Fidelity Batch Simulation Environment for Integrated Batch and Piloted Air Combat Simulation Analysis

A batch air combat simulation environment known as the Tactical Maneuvering Simulator (TMS) is presented. The TMS serves as a tool for developing and evaluating tactical maneuvering logics. The environment can also be used to evaluate the tactical implications of perturbations to aircraft performance or supporting systems. The TMS is capable of simulating air combat between any number of engagement participants, with practical limits imposed by computer memory and processing power. Aircraft are modeled using equations of motion, control laws, aerodynamics and propulsive characteristics equivalent to those used in high-fidelity piloted simulation. Databases representative of a modern high-performance aircraft with and without thrust-vectoring capability are included. To simplify the task of developing and implementing maneuvering logics in the TMS, an outer-loop control system known as the Tactical Autopilot (TA) is implemented in the aircraft simulation model. The TA converts guidance commands issued by computerized maneuvering logics in the form of desired angle-of-attack and wind axis-bank angle into inputs to the inner-loop control augmentation system of the aircraft. This report describes the capabilities and operation of the TMS.

A prospective, longitudinal analysis of injuries sustained by a large combat-deployed maneuver unit has not been previously performed. A detailed description of the combat casualty care statistics, distribution of wounds, and mechanisms of injury incurred by a U.S. Army Brigade Combat Team during "The Surge" phase of Operation Iraqi Freedom was performed using a centralized casualty database and an electronic medical record system. Among the 4,122 soldiers deployed, there were 500 combat wounds in 390 combat casualties. The combat casualty rate for the Brigade Combat Team was 75.7 per 1,000 soldier combat-years. The % killed in action (KIA) was 22.1%, and the %died of wounds was 3.2%. The distribution of these wounds was as follows: head/neck 36.2%, thorax 7.5%, abdomen 6.9%, and extremities 49.4%. The percentage of combat wounds showed a significant increase in the head/neck region (p < 0.0001) and a decrease in the extremities (p < 0.03) compared with data from World War II, Korea, and Vietnam. The percentage of thoracic wounds (p < 0.03) was significantly less than historical data from World War II and Vietnam. The %KIA was significantly greater in those soldiers injured by an explosion (26.3%) compared with those soldiers injured by a gunshot wound (4.6%; p = 0.003). Improvised explosive devices accounted for 77.7% of all combat wounds. There was a significantly higher proportion of head/neck wounds compared with previous U.S. conflicts. The 22.1% KIA was comparable with previous U.S. conflicts despite improvements in individual/vehicular body armor and is largely attributable to the lethality of improvised explosive devices. The lethality of a gunshot wound in Operation Iraqi Freedom has decreased to 4.6% with the use of individual body armor.

Combat-related intradural gunshot wound to the thoracic spine: significant improvement and neurologic recovery following bullet removal.

The vast majority of combat-related penetrating spinal injuries from gunshot wounds result in severe or complete neurological deficit. Treatment is based on neurological status, the presence of cerebrospinal fluid (CSF) fistulas, and local effects of any retained fragment(s). We present a case of a 46-year-old male who sustained a spinal gunshot injury from a 7.62-mm AK-47 round that became lodged within the subarachnoid space at T9-T10. He immediately suffered complete motor and sensory loss. By 24-48 hours post-injury, he had recovered lower extremity motor function fully but continued to have severe sensory loss (posterior cord syndrome). On post-injury day 2, he was evacuated from the combat theater and underwent a T9 laminectomy, extraction of the bullet, and dural laceration repair. At surgery, the traumatic durotomy was widened and the bullet, which was laying on the dorsal surface of the spinal cord, was removed. The dura was closed in a water-tight fashion and fibrin glue was applied. Postoperatively, the patient made a significant but incomplete neurological recovery. His stocking-pattern numbness and sub-umbilical searing dysthesia improved. The spinal canal was clear of the foreign body and he had no persistent CSF leak. Postoperative magnetic resonance imaging of the spine revealed contusion of the spinal cord at the T9 level. Early removal of an intra-canicular bullet in the setting of an incomplete spinal cord injury can lead to significant neurological recovery following even high-velocity and/or high-caliber gunshot wounds. However, this case does not speak to, and prior experience does not demonstrate, significant neurological benefit in the setting of a complete injury.

Explosive blast has been extensively used as a tactical weapon in Operation Iraqi Freedom (OIF) and more recently in Operation Enduring Freedom(OEF). The polytraumatic nature of blast injuries is evidence of their effectiveness,and brain injury is a frequent and debilitating form of this trauma. In-theater clinical observations of brain-injured casualties have shown that edema, intracranial hemorrhage, and vasospasm are the most salient pathophysiological characteristics of blast injury to the brain. Unfortunately, little is known about exactly how an explosion produces these sequelae as well as others that are less well documented. Consequently, the principal objective of the current report is to present a swine model of explosive blast injury to the brain. This model was developed during Phase I of the DARPA (Defense Advanced Research Projects Agency) PREVENT (Preventing Violent Explosive Neurotrauma) blast research program. A second objective is to present data that illustrate the capabilities of this model to study the proximal biomechanical causes and the resulting pathophysiological, biochemical,neuropathological, and neurological consequences of explosive blast injury to the swine brain. In the concluding section of this article, the advantages and limitations of the model are considered, explosive and air-overpressure models are compared, and the physical properties of an explosion are identified that potentially contributed to the in-theater closed head injuries resulting from explosions of improvised explosive devices (IEDs).

Temporal indiscriminateness: the case of cluster bombs.

PubMed

Cavanaugh, T A

2010-03-01

This paper argues that the current stock of anti-personnel cluster bombs are temporally indiscriminate, and, therefore, unjust weapons. The paper introduces and explains the idea of temporal indiscriminateness. It argues that to honor non-combatant immunity-in addition to not targeting civilians-one must adequately target combatants. Due to their high dud rate, cluster submunitions fail to target combatants with sufficient temporal accuracy, and, thereby, result in avoidable serious harm to non-combatants. The paper concludes that non-combatant immunity and the principle of discrimination require a moratorium on the use of current cluster munitions.

Increasing combat realism: the effectiveness of stun belt use on soldiers for the enhancement of live training and testing exercises

NASA Astrophysics Data System (ADS)

Schricker, Bradley C.; Antalek, Christopher

2006-05-01

The ability to make correct decisions while operating in a combat zone enables American and Coalition warfighters to better respond to any threats they may encounter due to the minimization of negative training the warfighter encountered during their live, virtual, and constructive (LVC) training exercises. By increasing the physical effects encountered by one's senses during combat scenarios, combat realism is able to be increased, which is a key component in the reduction in negative training. The use of LVC simulations for training and testing augmentation purposes depends on a number of factors, not the least of which is the accurate representation of the training environment. This is particularly true in the realm of tactical engagement training through the use of Tactical Engagement Simulation Systems (TESS). The training environment is perceived through human senses, most notably sight and hearing. As with other haptic devices, the sense of touch is gaining traction as a viable medium through which to express the effects of combat battle damage from the synthetic training environment to participants within a simulated training exercise. New developments in this field are promoting the safe use of an electronic stun device to indicate to a trainee that they have been hit by a projectile, from either direct or indirect fire, through the course of simulated combat. A growing number of examples suggest that this added output medium can greatly enhance the realism of a training exercise and, thus, improve the training value. This paper serves as a literature survey of this concept, beginning with an explanation of TESS. It will then focus on how the electronic stun effect may be employed within a TESS and then detail some of the noted pros and cons of such an approach. The paper will conclude with a description of potential directions and work.

Combat and herbicide exposures in Vietnam among a sample of American Legionnaires

DOE Office of Scientific and Technical Information (OSTI.GOV)

Stellman, S.D.; Stellman, J.M.; Sommer, J.F. Jr.

A cross-sectional survey of 6,810 randomly selected members of The American Legion in six states who served in the US Armed Forces during the Vietnam Era was conducted by a mailed questionnaire. Combat stress was evaluated by a previously validated eight-item scale. Exposure to Agent Orange and other herbicides was estimated via exposure probability index previously developed by the authors which uses an algorithm based on the combined Air Force and Joint Services HERBS files of spray data. Two-fifths of the men had served in Southeast Asia, generally at the same time during which the major proportion of herbicides weremore » used; the remaining subjects served elsewhere. Both combat and Agent Orange exposure exhibited distinct, meaningful distributions among Vietnam veterans with service in Southeast Asia and were also correlated with each other. Our analysis demonstrates conclusively that mere presence in Vietnam cannot be used as a proxy for exposure to Agent Orange. Categorization of Vietnam veterans according to herbicide exposure can be successfully accomplished, based on an existing detailed herbicide application data base. This analysis, together with the consistent dose-related results obtained in this series of papers on health and behavioral effects, demonstrates the utility of questionnaire-derived herbicide and combat exposure measures for epidemiologic study of Vietnam veterans.« less

Combat body armor and injuries to the head, face, and neck region: a systematic review.

PubMed

Tong, Darryl; Beirne, Ross

2013-04-01

There has been a reported increase in combat-related head, face, and neck (HFN) injuries among service personnel wearing combat body armor (CBA) that have deployed to Iraq and Afghanistan. Modern ceramic plate CBA has decreased the incidence of fatal-penetrating injuries to the torso but offers no protection to the limbs and face which remain exposed to gunshot wounds and fragments from explosive devices. The aim of this review was to systematically summarize the literature reporting on HFN injuries sustained by combat personnel wearing CBA and to highlight recommendations for increased protection to the facial region. Three major contributing factors were identified with this proportional increase in HFN injuries, namely the increased survivability of soldiers because of CBA, fragments injuries from explosive devices, and the lack of protection to the face and limbs. There appears to be no evidence to suggest that by virtue of wearing CBA the likelihood of sustaining an HFN injury increases as such, but a higher incidence of fragment injuries to the HFN region may be due to the more common use of improvised explosive devicess and other explosive devices. Further development of lightweight protection for the face is needed. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

Improved representation of situational awareness within a dismounted small combat unit constructive simulation

Lee, K. David; Colony, Mike

2011-06-01

Modeling and simulation has been established as a cost-effective means of supporting the development of requirements, exploring doctrinal alternatives, assessing system performance, and performing design trade-off analysis. The Army's constructive simulation for the evaluation of equipment effectiveness in small combat unit operations is currently limited to representation of situation awareness without inclusion of the many uncertainties associated with real world combat environments. The goal of this research is to provide an ability to model situation awareness and decision process uncertainties in order to improve evaluation of the impact of battlefield equipment on ground soldier and small combat unit decision processes. Our Army Probabilistic Inference and Decision Engine (Army-PRIDE) system provides this required uncertainty modeling through the application of two critical techniques that allow Bayesian network technology to be applied to real-time applications. (Object-Oriented Bayesian Network methodology and Object-Oriented Inference technique). In this research, we implement decision process and situation awareness models for a reference scenario using Army-PRIDE and demonstrate its ability to model a variety of uncertainty elements, including: confidence of source, information completeness, and information loss. We also demonstrate that Army-PRIDE improves the realism of the current constructive simulation's decision processes through Monte Carlo simulation.

While the relationship between combat exposure and alcohol problems is well-established, the role of perceptions of trauma is less understood. The goal of this study was to explore associations between National Guard (NG) and reserve soldiers' perceptions of combat experiences as traumatic and alcohol problems, and to examine marital satisfaction as a possible protective factor. The Operation: SAFETY study recruited US Army Reserve and NG soldiers and their partners to complete a questionnaire covering many physical and mental health, military service, and substance use topics. Negative binomial regression models examined the impact of perceived trauma of combat experiences on alcohol problems (N = 198). The potential role of marital satisfaction as a resiliency factor was also examined. The perception of combat experiences as traumatic was associated with increased risk of alcohol problems (risk ratio [RR] = 1.06, 95% confidence interval [CI] 1.01, 1.12; p = 0.024). Combat exposure itself showed no relationship. Marital satisfaction had a significant interaction with perceived combat trauma on alcohol problems (RR = 0.90, 95% CI 0.81, 0.99, p = 0.046), such that soldiers who perceived combat exposure as moderately-highly traumatic were less likely to have alcohol problems when they rated their marital satisfaction highly. Our results demonstrate that the perception of combat experiences as traumatic may be a greater contributor to adverse outcomes, such as alcohol problems, than mere combat exposure. They also demonstrate the importance of marital satisfaction as a resiliency factor, particularly at the highest levels of trauma.

Although caffeine is one of the most commonly used substances in combat sports, information about its ergogenic effects on these disciplines is very limited. To determine the effectiveness of ingesting a moderate dose of caffeine to enhance overall performance during a simulated Brazilian jiu-jitsu (BJJ) competition. Fourteen elite BJJ athletes participated in a double-blind, placebo-controlled experimental design. In a random order, the athletes ingested either 3 mg/kg body mass of caffeine or a placebo (cellulose, 0 mg/kg) and performed 2 simulated BJJ combats (with 20 min rest between them), following official BJJ rules. Specific physical tests such as maximal handgrip dynamometry, maximal height during a countermovement jump, permanence during a maximal static-lift test, peak power in a bench-press exercise, and blood lactate concentration were measured at 3 specific times: before the first combat and immediately after the first and second combats. The combats were video-recorded to analyze fight actions. After the caffeine ingestion, participants spent more time in offensive actions in both combats and revealed higher blood lactate values (P < .05). Performance in all physical tests carried out before the first combat was enhanced with caffeine (P < .05), and some improvements remained after the first combat (eg, maximal static-lift test and bench-press exercise; P < .05). After the second combat, the values in all physical tests were similar between caffeine and placebo. Caffeine might be an effective ergogenic aid for improving intensity and physical performance during successive elite BJJ combats.

The objective of the study was to evaluate the difference in the level of self dental assessment between different groups of soldiers: 115 combats and 115 non-combats. All the solders in this study where male, Jewish, with a service record of 12-48 months, ages 18-22 and born in Israel. The data was summarized, evaluated and tested by x2 - chi square and logistic regressions analysis. In the following parameters no significant differences were found regarding time past from last visit to the dentist, self assessment of dental condition, self assessment of need of dental treatment and the frequency of tooth brushing and sugar consumption. Significant differences were found in the percentage of smokers (59.1% among non-combat vs. 31.9% among combat), and in the dental anxiety level (55.3% among non-combat vs. 38% among combat). The main difference between these two groups is the nature of the social support and society surrounding them, a society that strengthens them and gives the feeling they can deal with fears and difficulties. An additional study should be done in which the soldiers self assessment should be compared to clinical examination. The importance of this study is that the non-combat group should be defined as a high risk population regarding dental anxiety.

The National Institute of Justice (NIJ) is the research arm of the Department of Justice. Through its Office of Science & Technology (OS&T), NIJ has actively pursued development of better tools for public safety agencies to combat terrorism since 1997, when, pursuant to the Anti-Terrorism and Effective Penalty Act of 1996 (P.L. 104 -132), it began development of technology to better enable law enforcement agencies to combat terrorism. NIJ quickly realized that effectively combating terrorism required a multi disciplinary, multi agency response. Additionally, it came to understand that, as noted by the Gilmore Commission, the best way to prepare the responder community to deal with the consequences of terrorist incidents, was to ``emphasize programs and initiatives that build appropriately on existing State and local capabilities for other emergencies and disasters.'' For example, an effective critical incident management system is just as important to the ability to deal with a terrorist attack, such as occurred at the World Trade Center, as with a major natural disaster or the crash of a commercial airliner or passenger train. Consequently, NIJ's efforts have evolved to focus on the responder community's common, unaddressed needs for better tools to deal with critical incidents. The Institutes efforts focus on five technology areas: infrastructure security, personnel location, explosives detection and remediation, communications and information technology and training, and development of standards.

Applications of Capstone depleted uranium aerosol risk data to military combat risk management.

Daxon, Eric G; Parkhurst, Mary Ann; Melanson, Mark A; Roszell, Laurie E

2009-03-01

Risks to personnel engaged in military operations include not only the threat of enemy firepower but also risks from exposure to other hazards such as radiation. Combatant commanders of the U.S. Army carefully weigh risks of casualties before implementing battlefield actions using an established paradigm that takes these risks into consideration. As a result of the inclusion of depleted uranium (DU) anti-armor ammunition in the conventional (non-nuclear) weapons arsenal, the potential for exposure to DU aerosols and its associated chemical and radiological effects becomes an element of the commanders' risk assessment. The Capstone DU Aerosol Study measured the range of likely DU oxide aerosol concentrations created inside a combat vehicle perforated with a DU munition, and the Capstone Human Health Risk Assessment (HHRA) estimated the associated doses and calculated risks. This paper focuses on the development of a scientific approach to adapt the risks from DU's non-uniform dose distribution within the body using the current U.S. Department of Defense radiation risk management approach. The approach developed equates the Radiation Exposure Status categories to the estimated radiological risks of DU and makes use of the Capstone-developed Renal Effects Group as a measure of chemical risk from DU intake. Recommendations are provided for modifying Army guidance and policy in order to better encompass the potential risks from DU aerosol inhalation during military operations.

Associations of coping processes with posttraumatic stress disorder symptoms in national guard/reserve service members deployed during the OEF-OIF era.

PubMed

Rodrigues, Camila S; Renshaw, Keith D

2010-10-01

Studies have identified coping processes as one potential factor influencing PTSD in veterans. This study examined the associations between coping, combat exposure, and PTSD among 218 National Guard veterans deployed overseas since 2001. Problem-focused coping was unrelated to combat exposure and PTSD symptoms. In contrast, increased levels of emotion focused coping (EFC) were found in veterans who reported higher levels of combat exposure. Moreover, the severity of combat was a curvilinear moderator of the relation between coping process and PTSD, such that EFC was unrelated to PTSD symptom severity at low levels of combat, associated with higher symptom severity at moderate levels of combat, and associated with lower symptom severity at high levels of combat. These findings indicate that the type and severity of trauma may moderate the association of coping and psychological outcomes, and that these associations might not be linear.

Details of the collaborative program amongst the Virtual Reality Medical Center (VRMC), Office of Naval Research, the Naval Medical Center San Diego (NMCSD) and the Navy Hospital Camp Pendleton are discussed as is the VRGET outcomes of significant reductions in PTSD symptoms severity. We also described the estimated cost-effectiveness of VRGET for the treatment of combat-related PTSD, as contrasted to Treatment as Usual (TAU) for combat-related PTSD.

From the laboratory to the soldier: providing tactical behaviors for Army robots

NASA Astrophysics Data System (ADS)

Knichel, David G.; Bruemmer, David J.

2008-04-01

The Army Future Combat System (FCS) Operational Requirement Document has identified a number of advanced robot tactical behavior requirements to enable the Future Brigade Combat Team (FBCT). The FBCT advanced tactical behaviors include Sentinel Behavior, Obstacle Avoidance Behavior, and Scaled Levels of Human-Machine control Behavior. The U.S. Army Training and Doctrine Command, (TRADOC) Maneuver Support Center (MANSCEN) has also documented a number of robotic behavior requirements for the Army non FCS forces such as the Infantry Brigade Combat Team (IBCT), Stryker Brigade Combat Team (SBCT), and Heavy Brigade Combat Team (HBCT). The general categories of useful robot tactical behaviors include Ground/Air Mobility behaviors, Tactical Mission behaviors, Manned-Unmanned Teaming behaviors, and Soldier-Robot Interface behaviors. Many DoD research and development centers are achieving the necessary components necessary for artificial tactical behaviors for ground and air robots to include the Army Research Laboratory (ARL), U.S. Army Research, Development and Engineering Command (RDECOM), Space and Naval Warfare (SPAWAR) Systems Center, US Army Tank-Automotive Research, Development and Engineering Center (TARDEC) and non DoD labs such as Department of Energy (DOL). With the support of the Joint Ground Robotics Enterprise (JGRE) through DoD and non DoD labs the Army Maneuver Support Center has recently concluded successful field trails of ground and air robots with specialized tactical behaviors and sensors to enable semi autonomous detection, reporting, and marking of explosive hazards to include Improvised Explosive Devices (IED) and landmines. A specific goal of this effort was to assess how collaborative behaviors for multiple unmanned air and ground vehicles can reduce risks to Soldiers and increase efficiency for on and off route explosive hazard detection, reporting, and marking. This paper discusses experimental results achieved with a robotic countermine system that utilizes autonomous behaviors and a mixed-initiative control scheme to address the challenges of detecting and marking buried landmines. Emerging requirements for robotic countermine operations are outlined as are the technologies developed under this effort to address them. A first experiment shows that the resulting system was able to find and mark landmines with a very low level of human involvement. In addition, the data indicates that the robotic system is able to decrease the time to find mines and increase the detection accuracy and reliability. Finally, the paper presents current efforts to incorporate new countermine sensors and port the resulting behaviors to two fielded military systems for rigorous assessing.

Combat games

Ardema, M. D.; Heymann, M.; Rajan, N.

1985-01-01

A mathematical formulation is proposed of a combat game between two opponents with offensive capabilities and offensive objective is proposed. Resolution of the combat involves solving two differential games with state constraints. Depending on the game dynamics and parameters, the combat can terminate in one of four ways: the first player wins; the second player wins; a draw (neither wins); or joint capture. In the first two cases, the optimal strategies of the two players are determined from suitable zero-sum games, whereas in the latter two the relevant games are nonzero-sum. Further, to avoid certain technical difficulties, the concept of a delta-combat game is introduced.

Improved diagnosis and treatment of traumatic brain injury (TBI) and posttraumatic stress disorder (PTSD) are needed for our military and veterans, their families, and society at large. Advances in brain imaging offer important biomarkers of structural, functional, and metabolic information concerning the brain. This article reviews the application of various imaging techniques to the clinical problems of TBI and PTSD. For TBI, we focus on findings and advances in neuroimaging that hold promise for better detection, characterization, and monitoring of objective brain changes in symptomatic patients with combat-related, closed-head brain injuries not readily apparent by standard computed tomography or conventional magnetic resonance imaging techniques.

A research program investigating the use of artificial intelligence (AI) techniques to aid in the development of a Tactical Decision Generator (TDG) for Within Visual Range air combat engagements is discussed. The application of AI programming and problem solving methods in the development and implementation of the Computerized Logic For Air-to-Air Warfare Simulations (CLAWS), a second generation TDG, is presented. The knowledge-based systems used by CLAWS to aid in the tactical decision-making process are outlined in detail, and the results of tests to evaluate the performance of CLAWS versus a baseline TDG developed in FORTRAN to run in real time in the Langley Differential Maneuvering Simulator, are presented. To date, these test results have shown significant performance gains with respect to the TDG baseline in one-versus-one air combat engagements, and the AI-based TDG software has proven to be much easier to modify and maintain than the baseline FORTRAN TDG programs.

The mental health of UK ex-servicemen with a combat-related or a non-combat-related visual impairment: does the cause of visual impairment matter?

Since the start of the conflicts in Iraq and Afghanistan, the numbers of young service personnel who have sustained a combat-related visual impairment have increased. This cross-sectional study examined the mental well-being of ex-servicemen (aged 22-55 years) with a visual impairment and determined if the mental health of those with a combat-related visual impairment differed from those whose visual impairment is not combat-related. Male ex-service personnel with a visual impairment completed a telephone interview assessing the presence of depressive symptomatology, probable anxiety disorder, post-traumatic stress disorder (PTSD) symptomatology and alcohol misuse. Data were analysed using descriptive statistics. 77 participants were included in the study, reflecting a response rate of 76.2%. Of those with complete data (n=74), 20 ex-servicemen had a combat-related visual impairment. Among ex-service personnel with a combat-related visual impairment, 10.0% (95% CI 0 to 23.2) screened positive for a probable depression, 25.0% (95% CI 6.0 to 44.0) for probable anxiety and 10.0% (95% CI 0 to 23.2) for probable PTSD. The prevalence of probable depression and probable PTSD differed among those with a non-combat-related visual impairment, namely 18.5% (95% CI 8.1 to 28.9) and 16.7% (95% CI 6.8 to 26.7), respectively. Probable anxiety was 18.5% (95% CI 8.1 to 28.9) among non-combat-related visually impaired ex-service personnel. 45.0% (95% CI 23.2 to 66.8) of combat-related visually impaired personnel reported hazardous drinking, compared with 20.4% (95% CI 9.7 to 31.2) of those with a non-combat-related visual impairment. Mental health problems were prevalent among visually impaired younger ex-servicemen. No statistically significant differences were found in the prevalence of mental health problems among ex-servicemen with a combat-related visual impairment compared with those with a non-combat-related visual impairment.

Since the discovery of antibiotics by Sir Alexander Fleming they have been used throughout medicine and play a vital role in combating microorganisms. However, with their vast use, development of resistance has become more prevalent and their use is currently under threat. Antibiotic resistance poses a global threat to human and animal health, with many bacterial species having developed some form of resistance and in some cases within a year of first exposure to antimicrobial agents. This review aims to examine some of the mechanisms behind resistance. Additionally, re-engineering organisms, re-sensitizing bacteria to antibiotics and gene-editing techniques such as the clustered regularly interspaced short palindromic repeats-Cas9 system are providing novel approaches to combat bacterial resistance. To that extent, we have reviewed some of these novel and innovative technologies.

The study of RNA has continually emphasized the structural and functional versatility of RNA molecules. This versatility has inspired translational and clinical researchers to explore the utility of RNA-based therapeutic agents for a wide variety of medical applications. Several RNA therapeutics, with diverse modes of action, are being evaluated in large late-stage clinical trials, and many more are in early clinical development. Hundreds of patients are enrolled in large trials testing messenger RNAs to combat cancer, small interfering RNAs to treat renal and hepatic disorders, and aptamers to combat ocular and cardiovascular disease. Results from these studies are generating considerable interest among the biomedical community and the public and will be important for the future development of this emerging class of therapeutic agents.

Prehospital and emergency care research at the US Army Institute of Surgical Research: enabling the next great leap in combat casualty survival.

PubMed

Gerhardt, Robert T

2011-01-01

Minimizing preventable death continues to be a primary focus of the combat casualty care research community, and of the Army Medical Department as a whole. Toward that end, tremendous successes have been realized in resuscitative surgery, critical care, rehabilitation, preventive medicine, and in our collective ability to project effective medical care into the most austere locations throughout the globe. Innovation in the care rendered outside of theater hospitals or strategic air evacuation conveyances, however, has not kept the same pace. The US military experience in World War II, Korea, and Vietnam served as a prime source for the development of the tactics, techniques, and procedures which spawned modern civilian sector trauma care and emergency medical services. But this ascendance was driven by the dedicated medics, corpsmen, physicians, nurses, and allied health practitioners from those conflicts who left the military for the civilian sector, leaving their replacements, in many cases, to repeat the same mistakes, and to relearn hard lessons that otherwise might have been assimilated had they been effectively captured and integrated into doctrine and training. A prime example of this phenomenon is the recent acknowledgement of the "en route care gap" existing in tactical medical evacuation. The US Army Institute of Surgical Research (USAISR) and the Army emergency medicine community have made a significant commitment toward elucidating the requirements, capability gaps, and a way-forward in search of the development of an integrated prehospital combat casualty care system, nested within the Joint Theater Trauma System. This paper examines specific research programs, concept development, and collaborations with other Army, joint, and civilian center organizations which comprise the USAISR Prehospital and Emergency Care Research Program, including the Remote Damage Control Resuscitation initiative, Emergency Telemedical Direction of Role-I providers, Combat Medical Voice Documentation System, and establishment of the Remote Trauma Outcomes Research Network.

Chronic inflammation may be involved in combat-related post-traumatic stress disorder (PTSD) and may help explain comorbid physical diseases. However, the extent to which combat exposure per se, depression, or early life trauma, all of which are associated with combat PTSD, may confound the relationship between PTSD and inflammation is unclear. We quantified interleukin (IL)-6, IL-1β, tumor necrosis factor (TNF)-α, interferon (IFN)-γ, and C-reactive protein (CRP) in 51 combat-exposed males with PTSD and 51 combat-exposed males without PTSD, and assessed PTSD and depression severity as well as history of early life trauma. To decrease the possibility of Type I errors, we summed standardized scores of IL-1β, IL-6, TNFα, IFNγ and CRP into a total "pro-inflammatory score". PTSD symptom severity was assessed with the Clinician Administered PTSD Scale (CAPS) rating scale. Subjects with PTSD had significantly higher pro-inflammatory scores compared to combat-exposed subjects without PTSD (p=0.006), and even after controlling for early life trauma, depression diagnosis and severity, body mass index, ethnicity, education, asthma/allergies, time since combat and the use of possibly confounding medications (p=0.002). Within the PTSD group, the pro-inflammatory score was not significantly correlated with depressive symptom severity, CAPS total score, or with the number of early life traumas. Combat-related PTSD in males is associated with higher levels of pro-inflammatory cytokines, even after accounting for depression and early life trauma. These results, from one of the largest studies of inflammatory cytokines in PTSD to date, suggest that immune activation may be a core element of PTSD pathophysiology more so than a signature of combat exposure alone.

An association between combat exposure and postdeployment behavioral health problems has been demonstrated among U.S. military service members returning from Afghanistan or Iraq in predominantly male samples, yet few studies have focused on the experiences of women. Using data from the longitudinal, observational Substance Use and Psychological Injury Combat (SUPIC) Study, we explored the self-report of 4 combat exposure items and postdeployment behavioral health screening results for 42,397 Army enlisted women who had returned from Afghanistan or Iraq from fiscal years 2008 through 2011. We ran multivariate logistic regression models to examine how a constructed composite combat exposure score (0, 1, 2, 3+) was associated with screening positive postdeployment for posttraumatic stress disorder (PTSD), depression, and at-risk drinking among active duty (AD) and National Guard/Reserve (NG/R) women. AD and NG/R women commonly reported being wounded, injured, assaulted, or hurt (17.3% and 29.0%, respectively). In all 6 multivariate models, Army women with any report of combat exposure had increased odds of the behavioral health problem (i.e., PTSD, depression, or at-risk drinking). The magnitude of the association between combat exposure and PTSD was most striking, indicating increased odds of PTSD as combat exposure score increased. AD and NG/R women with a combat exposure score of 3+ had increased odds of PTSD, 20.7, 95% confidence interval (CI) [17.0, 25.1] and 27.8, 95% CI [21.0, 36.9], respectively. Women who report combat exposure may benefit from early prevention and confidential intervention to promote postdeployment health and reduce long-term behavioral health problems.

Adaptive Planning: Understanding Organizational Workload to Capability/ Capacity through Modeling and Simulation

NASA Technical Reports Server (NTRS)

Hase, Chris

2010-01-01

In August 2003, the Secretary of Defense (SECDEF) established the Adaptive Planning (AP) initiative [1] with an objective of reducing the time necessary to develop and revise Combatant Commander (COCOM) contingency plans and increase SECDEF plan visibility. In addition to reducing the traditional plan development timeline from twenty-four months to less than twelve months (with a goal of six months)[2], AP increased plan visibility to Department of Defense (DoD) leadership through In-Progress Reviews (IPRs). The IPR process, as well as the increased number of campaign and contingency plans COCOMs had to develop, increased the workload while the number of planners remained fixed. Several efforts from collaborative planning tools to streamlined processes were initiated to compensate for the increased workload enabling COCOMS to better meet shorter planning timelines. This paper examines the Joint Strategic Capabilities Plan (JSCP) directed contingency planning and staffing requirements assigned to a combatant commander staff through the lens of modeling and simulation. The dynamics of developing a COCOM plan are captured with an ExtendSim [3] simulation. The resulting analysis provides a quantifiable means by which to measure a combatant commander staffs workload associated with development and staffing JSCP [4] directed contingency plans with COCOM capability/capacity. Modeling and simulation bring significant opportunities in measuring the sensitivity of key variables in the assessment of workload to capability/capacity analysis. Gaining an understanding of the relationship between plan complexity, number of plans, planning processes, and number of planners with time required for plan development provides valuable information to DoD leadership. Through modeling and simulation AP leadership can gain greater insight in making key decisions on knowing where to best allocate scarce resources in an effort to meet DoD planning objectives.

To examine the association between the 5-HTTLPR polymorphism of the serotonin transporter (SLC6A4) gene, combat exposure, and posttraumatic stress disorder (PTSD) diagnosis and among two samples of combat-exposed veterans. The first sample included 550 non-Hispanic Black (NHB) combat-exposed veterans. The second sample included 555 non-Hispanic White (NHW) combat-exposed veterans. Participants were genotyped for the 5-HTTLPR/rs25531 variants of the SLC6A4 gene. A structured clinical interview was used to diagnose PTSD. Combat and civilian trauma exposure were assessed with validated self-report instruments. Logistic regression was used to test for main effects of 5-HTTLPR on PTSD diagnosis as well as gene x environment (GxE) interactions after adjusting for sex, ancestry proportion scores, civilian trauma exposure, and combat exposure. Within the NHB sample, a significant additive effect was observed for 5-HTTLPR (OR = 1.502, p = .0025), such that the odds of having a current diagnosis of PTSD increased by 1.502 for each additional S' allele. No evidence for an association between 5-HTTLPR and PTSD was observed in the NHW sample. In addition, no evidence for combat x 5-HTTLPR effects were observed in either sample. The present study suggests that there may be an association between 5-HTTLPR genotype and PTSD diagnosis among NHB veterans; however, no evidence for the hypothesized 5-HTTLPR x combat interaction was found.

The comparative behaviour of two combat boots under impact.

2012-04-01

Improvised explosive devices have become the characteristic weapon of conflicts in Iraq and Afghanistan. While little can be done to mitigate against the effects of blast in free-field explosions, scaled blast simulations have shown that the combat boot can attenuate the effects on the vehicle occupants of anti-vehicular mine blasts. Although the combat boot offers some protection to the lower limb, its behaviour at the energies seen in anti-vehicular mine blast has not been documented previously. The sole of eight same-size combat boots from two brands currently used by UK troops deployed to Iraq and Afghanistan were impacted at energies of up to 518 J, using a spring-assisted drop rig. The results showed that the Meindl Desert Fox combat boot consistently experienced a lower peak force at lower impact energies and a longer time-to-peak force at higher impact energies when compared with the Lowa Desert Fox combat boot. This reduction in the peak force and extended rise time, resulting in a lower energy transfer rate, is a potentially positive mitigating effect in terms of the trauma experienced by the lower limb. Currently, combat boots are tested under impact at the energies seen during heel strike in running. Through the identification of significantly different behaviours at high loading, this study has shown that there is rationale in adding the performance of combat boots under impact at energies above those set out in international standards to the list of criteria for the selection of a combat boot.

This article summarizes presentations from a 2014 United States Department of Defense (DoD) Health Affairs Women in Combat symposium addressing physiological, musculoskeletal injury, and optimized physical training considerations from the operational physical performance section. The symposium was held to provide a state-of-the-science meeting on the U.S. DoD's rescinding of the ground combat exclusion policy opening up combat-centric occupations to women. Physiological, metabolic, body composition, bone density, cardiorespiratory fitness, and thermoregulation differences between men and women were briefly reviewed. Injury epidemiological data are presented within military training and operational environments demonstrating women to be at a higher risk for musculoskeletal injuries than men. Physical training considerations for improved muscle strength and power, occupational task performance, load carriage were also reviewed. Particular focus of this article was given to translating physiological and epidemiological findings from the literature on these topics toward actionable guidance and policy recommendations for military leaders responsible for military physical training doctrine: (1) inclusion of resistance training with special emphasis on strength and power development (i.e., activation of high-threshold motor units and recruitment of type II high-force muscle fibers), upper-body strength development, and heavy load carriage, (2) moving away from "field expediency" as the major criteria for determining military physical training policy and training implementation, (3) improvement of load carriage ability with emphasis placed on specific load carriage task performance, combined with both resistance and endurance training, and (4) providing greater equipment resources, coaching assets, and increased training time dedicated to physical readiness training.

Central nervous system (CNS) adrenergic hyperresponsiveness may be involved in the pathophysiology of posttraumatic stress disorder (PTSD). Two Vietnam combat veterans with PTSD prescribed the centrally active alpha1-adrenergic antagonist prazosin for symptoms of benign prostatic hypertrophy unexpectedly reported elimination of combat trauma nightmares. This observation prompted an open-label feasibility trial of prazosin for combat trauma nightmares in chronic combat-induced PTSD. Four consecutively identified combat veterans with chronic DSM-IV PTSD and severe intractable combat trauma nightmares participated in an 8-week open trial of escalating-dose prazosin. Nightmare severity response was rated using the nightmare item of the Clinician Administered PTSD Scale and the Clinical Global Impressions-Change scale. The 2 patients who achieved a daily prazosin dose of at least 5 mg were markedly improved, with complete elimination of trauma nightmares and resumption of normal dreaming. The 2 subjects limited to 2 mg of prazosin to avoid excessive blood pressure reduction were moderately improved with at least 50% reduction in nightmare severity. These clinical observations, together with neurobiological evidence for alpha1-adrenergic regulation of CNS neurobiological systems relevant to PTSD, provide rationale for placebo-controlled trials of prazosin for PTSD combat trauma nightmares.

Civil wars are characterized by intense forms of violence, such as torture, maiming and rape. Political scientists suggest that this form of political violence is fostered through the provision of particular intrinsic and extrinsic rewards to combatants. In the field of psychology, the perpetration of this kind of cruelty is observed to be positively linked to appetitive aggression. Over time, combatants start to enjoy the fights and even the perpetration of atrocities. In this study, we examine how receiving rewards (intrinsic versus extrinsic) influence the level of appetitive aggression exhibited by former combatants. We surveyed 95 former combatants in the eastern provinces of the Democratic Republic of the Congo. Linear regression analyses reveal that intrinsic as well as extrinsic rewards are linked to the former combatants' Appetitive Aggression score. However, this relationship is partly determined by the way in which combatants are recruited: While abducted combatants seem to react more strongly to extrinsic rewards, the score of those that joined voluntarily is primarily determined by intrinsic rewards. We conclude that receiving rewards influence the level of appetitive aggression. However, which type of rewards (intrinsic versus extrinsic) is of most importance is determined by the way combatants are recruited.

A survey on the measure of combat readiness

Measuring the combat readiness in military forces involves the measures of tangible and intangible elements of combat power. Though these measures are applicable, the mathematical models and formulae used focus mainly on either the tangible or the intangible elements. In this paper, a review is done to highlight the research gap in the formulation of a mathematical model that incorporates tangible elements with intangible elements to measure the combat readiness of a military force. It highlights the missing link between the tangible and intangible elements of combat power. To bridge the gap and missing link, a mathematical model could be formulated that measures both the tangible and intangible aspects of combat readiness by establishing the relationship between the causal (tangible and intangible) elements and its effects on the measure of combat readiness. The model uses multiple regression analysis as well as mathematical modeling and simulation which digest the capability component reflecting its assets and resources, the morale component reflecting human needs, and the quality of life component reflecting soldiers' state of satisfaction in life. The results of the review provide a mean to bridge the research gap through the formulation of a mathematical model that shows the total measure of a military force's combat readiness. The results also significantly identify parameters for each of the variables and factors in the model.

Combating substance misuse: competences and preparation of special education department students.

This study examines Jordanian special education department students' competences and preparation relating to combating substance misuse (SM). Thematic analysis was performed on data from interviews with 150 students. Some participants denied the possibility of addiction among students with disabilities, and presented negative attitudes toward their role in combating SM. In general, the participants displayed low levels of professionalism relating to combating SM, and the results revealed that they felt that their preparation programme had been inadequate and they desired more courses that related to combating SM. These results suggest that Jordanian Universities should emphasise the role of teachers in a preventive approach to SM.

To develop and assess impact of a focused review of International Trauma Life Support (ITLS) and combat casualty care with hands-on procedure training for U.S. Army medics deploying to Iraq. The setting was a U.S. Army Medical Department Center and School and Camp Eagle, Iraq. Investigators developed and implemented a command-approved prospective educational intervention with a post hoc survey. Subjects completed a three-day course with simulator and live-tissue procedure laboratories. At deployment's end, medics were surveyed for experience, confidence, and preparedness in treating various casualty severity levels. Investigators used two-tailed t-test with unequal variance for continuous data and chi-square for categorical data. Twenty-nine medics deployed. Eight completed the experimental program. Twenty-one of 25 (84%) available medics completed the survey including six of the eight (75%) experimental medics. The experimental group reported significantly greater levels of preparedness and confidence treating "minimal," "delayed," and "immediate" casualties at arrival in Iraq. These differences dissipated progressively over the time course of the deployment. This experimental program increased combat medic confidence and perceived level of preparedness in treating several patient severity levels. Further research is warranted to determine if the experimental intervention objectively improves patient care quality and translates into lives saved early in deployment.

"To care for him who shall have borne the battle and for his widow and his orphan" (Abraham Lincoln): the Department of Veterans Affairs polytrauma system of care.

PubMed

Sigford, Barbara J

2008-01-01

The initiation of combat in Iraq and Afghanistan has resulted in a new cohort of active-duty service members and veterans seeking rehabilitation care through the U.S. Department of Veterans Affairs (VA). Service members injured in combat most often sustain multiple injuries (polytrauma) and require a unique service delivery model to meet their needs. The VA recognized this need and responded with the development of the Polytrauma System of Care (PSC). This national system of care balances access and expertise to provide specialized life-long care to the combat injured. The PSC is comprised of: 4 specialized regional rehabilitation centers that are accredited in brain injury by the Commission on Accreditation of Rehabilitation Facilities; 21 specialized outpatient and subacute rehabilitation programs; designated polytrauma teams at smaller, more remote VA facilities; and a point of contact at all other VA facilities. In addition, the PSC has developed a proactive case-management model, a specialized telehealth network, guidelines for long-term follow-up, and services for those individuals who are unable to return home. The following commentary and articles provide additional detail on this new and unique system of care.

Are there atheists in foxholes? Combat intensity and religious behavior.

2013-09-01

After battle, the moral and mortality stresses influence different soldiers in different ways. Using two large-scale surveys of World War II veterans, this research investigates the impact of combat on religiosity. Study 1 shows that as combat became more frightening, the percentage of soldiers who reported praying rose from 42 to 72%. Study 2 shows that 50 years later, many soldiers still exhibited religious behavior, but it varied by their war experience. Soldiers who faced heavy combat (vs. no combat) attended church 21% more often if they claimed their war experience was negative, but those who claimed their experience was positive attended 26% less often. The more a combat veteran disliked the war, the more religious they were 50 years later. While implications for counselors, clergy, support groups, and health practitioners are outlined, saying there are no atheists in foxholes may be less of an argument against atheism than it is against foxholes.

UNEQUAL RISK: COMBAT OCCUPATIONS IN THE VOLUNTEER MILITARY

PubMed Central

MacLEAN, ALAIR; PARSONS, NICHOLAS L.

2011-01-01

This study evaluates the characteristics of the men who served in the volunteer military in combat occupations. It examines whether these characteristics stem from supply-side or demand-side decisions, or reflect class bias. The findings suggest that, on the supply side, men who had greater academic abilities were more likely to go to college, thereby avoiding military service and the possibility of serving in a combat occupation. On the demand side, the armed forces were more likely to exclude men with lower academic abilities but were more likely to assign such men in the military to combat occupations. Net of the impacts of these supply-side and demand-side decisions, men who served in combat occupations still differed from those who did not in terms of their family background. The impact of family background was stronger on entering the military than on being assigned to combat occupations once in the military. PMID:21691446

In 2013, the U.S. Army began developing physical tests to predict a recruit's ability to perform the critical, physically demanding tasks (CPDTs) of combat arms jobs previously not open to women. The purpose of this paper is to describe the methodology and results of analyses of the accuracy and inclusiveness of the critical physically demanding task list. While the job analysis included seven combat arms jobs, only data from the 19D Cavalry Scout occupation are presented as the process was similar for all seven jobs. Job analysis METHODS: As the foundation, senior subject matter experts from each job reviewed materials and reached consensus on the CPDTs and performance standards for each job. The list was reviewed by Army leadership and provided to the researchers. The job analysis consisted of reviewing job and task related documents and field manuals, observing >900 soldiers performing the 32 CPDTs, conducting two focus groups for each job, and analyzing responses to widely distributed job analysis questionnaires. Of the 32 CPDTs identified for seven combat jobs, nine were relevant to 19D soldiers. Focus group discussions and job analysis questionnaire results supported the tasks and standards identified by subject matter experts while also identifying additional tasks. The tasks identified by subject matter experts were representative of the physically demanding aspects of the 19D occupation. Published by Elsevier Ltd.

Optimizing fitness for duty and post-combat clinical services for military personnel and combat veterans with ADHD—a systematic review of the current literature

PubMed Central

Ivanov, Iliyan; Yehuda, Rachel

2014-01-01

Background Attention deficit hyper activity disorder (ADHD) is a developmental disorder, most often diagnosed in childhood, and characterized by hyperactivity and inattention that negatively impacts one's ability to function and fulfill social and personal obligations. Individuals with past history of ADHD may enlist in the military under certain conditions, however the full impact of military training and deployment of later in life ADHD symptoms is unclear. It is of particular interest how military experience may affect ADHD in remission and if such individuals might be at elevated risk for relapse of ADHD symptoms. Method We performed a systematic review f the available literature including the Department of Defense (DOD) guidelines for both eligibility to enlist and fitness for deployment based on reported history and current symptomatology of ADHD. Results The after care for veterans with ADHD relapse is inconsistent and presents with number of challenges. We evaluate the DOD policies regarding the implications of ADHD for fitness for military service and post-combat mental health. Conclusion The full extend of the interaction between pre-existing ADHD and post-combat PTSD are not fully understood. The development of comprehensive and clear algorithms for diagnosing and treating ADHD in the military before and after deployment will have a strong positive impact on the quality of care delivered to soldiers and veterans.

A postmortem human brain collection to study posttraumatic stress disorder (PTSD) is critical for uncovering the molecular mechanisms that contribute to this psychiatric disorder. We describe here the PTSD brain collection at the Lieber Institute for Brain Development in Baltimore, Maryland, consisting of postmortem brain donations acquired between 2012 and 2017. Thus far, 87 brains from individuals meeting DSM-5 criteria for PTSD were collected after consent was obtained from legal next-of-kin, and subsequently clinically characterized for molecular studies. PTSD brain donors had high rates of comorbid diagnoses, including depression (62.1%), substance abuse (74.7%), drug-related death (69.0%), and suicide completion (17.2%). PTSD cases were subdivided into two categories: combat-related PTSD (n = 24) and noncombat/domestic PTSD (n = 63). The major differences between the combat-related and domestic PTSD cohorts were sex, drug-related death, and the prevalence of bipolar disorder (BPD) comorbidity. The combat-related group was entirely male, with only one BPD subject (4.2%), and had significantly fewer drug-related deaths (45.8%) in contrast to the domestic group (31.8% male, 36.5% bipolar, and 77.8% drug-related deaths). Medical examiners' offices, particularly in areas with higher military populations, are an excellent source for PTSD brain donations of both combat-related and domestic PTSD. © 2017 Wiley Periodicals, Inc.

Although there is literature evaluating infectious complications associated with combat-related injuries from Iraq and Afghanistan, none have evaluated pneumonia specifically. Therefore, we assessed a series of pneumonia cases among wounded military personnel admitted to Landstuhl Regional Medical Center, and then evacuated further to participating U.S. military hospitals. Of the 423 casualties evacuated to the U.S., 36 developed pneumonia (8.5%) and 30 of these (83.3%) were ventilator-associated. Restricting to 162 subjects admitted to intensive care, 30 patients had pneumonia (18.5%). The median Injury Severity Score was higher among subjects with pneumonia (23.0, versus 6.0; p<0.01). There were 61 first-isolate respiratory specimens recovered from 31 pneumonia subjects, of which 56.1% were gram-negative, 18.2% were gram-positive, and 18.2% were fungal. Staphylococcus aureus and Pseudomonas aeruginosa were most commonly recovered (10.6%, and 9.1%, respectively). Thirteen bacterial isolates (26.5%) were multidrug-resistant. Outcome data were available for 32 patients, of which 26 resolved their infection without progression, 5 resolved after initial progression, and 1 died. Overall, combat-injured casualties suffer a relatively high rate of pneumonia, particularly those requiring mechanical ventilation. Although gram-negative pathogens were common, S. aureus was most frequently isolated. Continued focus on pneumonia prevention strategies is necessary for improving combat care. PMID:25562865

Using data from a prospective cohort study of U.S. service members who joined after September 11, 2001 to determine incidence rates and comorbidities of mental and behavioral disorders. Calculated age and sex adjusted incidence rates of mental and behavioral conditions determined by validated instruments and electronic medical records. Of 10,671 service members, 3,379 (32%) deployed between baseline and follow-up, of whom 49% reported combat experience. Combat deployers had highest incidence rates of post-traumatic stress disorder (PTSD) (25 cases/1,000 person-years [PY]), panic/anxiety (21/1,000 PY), and any mental disorder (34/1,000 PY). Nondeployers had substantial rates of mental conditions (11, 13, and 18 cases/1,000 PY). Among combat deployers, 12% screened positive for mental disorder, 59% binge drinking, 16% alcohol problem, 19% cigarette smoking, and 20% smokeless tobacco at follow-up. Of those with recent PTSD, 73% concurrently developed >1 incident mental or behavioral conditions. Of those screening positive for PTSD, 11% had electronic medical record diagnosis. U.S. service members joining during recent conflicts experienced high rates of mental and behavioral disorders. Highest rates were among combat deployers. Most cases were not represented in medical codes, suggesting targeted interventions are needed to address the burden of mental disorders among service members and Veterans.

Falco, M.; Smith, R.

1982-01-01

A computational procedure employing a stochastic learning method in conjunction with dynamic simulation of helicopter flight and weapon system operation was used to derive helicopter maneuvering strategies. The derived strategies maximize either survival or kill probability and are in the form of a feedback control based upon threat visual or warning system cues. Maneuverability parameters implicit in the strategy development include maximum longitudinal acceleration and deceleration, maximum sustained and transient load factor turn rate at forward speed, and maximum pedal turn rate and lateral acceleration at hover. Results are presented in terms of probability of skill for all combat initial conditions for two threat categories.

Hypnotherapeutic olfactory conditioning (HOC): case studies of needle phobia, panic disorder, and combat-induced PTSD.

PubMed

Abramowitz, Eitan G; Lichtenberg, Pesach

2009-04-01

The authors developed a technique, which they call hypnotherapeutic olfactory conditioning (HOC), for exploiting the ability of scents to arouse potent emotional reactions. During hypnosis, the patient learns to associate pleasant scents with a sense of security and self-control. The patient can subsequently use this newfound association to overcome phobias and prevent panic attacks. This may be especially effective for posttraumatic stress disorder (PTSD) with episodes of anxiety, flashbacks, and dissociation triggered by smells. The authors present 3 cases, patients with needle phobia, panic disorder, and combat-induced PTSD who were successfully treated with the HOC technique.

Combat trauma may affect servicemen from indigenous, traditional communities in ways that warrant special attention. The Bedouins, who enlist in the Israel Defense Forces (IDF) voluntarily, represent a unique, closed, collectivist cultural minority, potentially in a predicament in light of ongoing sociopolitical events. This paper summarizes findings and lessons learned from a community study of Bedouin IDF servicemen and their families residing in Israel’s Western Galilee. This is the only research endeavor to have addressed trauma exposure and posttraumatic reactions in this community. The sampling strategies and interview schedule were designed in consideration of participation barriers typical of hard-to-reach populations. Data collection followed an extended phase of liaising with key informants and building trust. Study limitations are discussed in terms of the challenges presented by this type of research. Interviews conducted with 317 men, 129 wives, and 67 mothers revealed high levels of trauma exposure and posttraumatic stress disorder (PTSD) in the men, and related distress in wives and mothers, but not in the children. The role of aggression in mediating the impact of PTSD and concepts such as shame, the loss of personal resources, and beliefs about retribution are highlighted as key issues for a culturally relevant understanding of traumatized indigenous communities.

Seminal fluid of honeybees contains multiple mechanisms to combat infections of the sexually transmitted pathogen Nosema apis.

The societies of ants, bees and wasps are genetically closed systems where queens only mate during a brief mating episode prior to their eusocial life and males therefore provide queens with a lifetime supply of high-quality sperm. These ejaculates also contain a number of defence proteins that have been detected in the seminal fluid but their function and efficiency have never been investigated in great detail. Here, we used the honeybee Apis mellifera and quantified whether seminal fluid is able to combat infections of the fungal pathogen Nosema apis, a widespread honeybee parasite that is also sexually transmitted. We provide the first empirical evidence that seminal fluid has a remarkable antimicrobial activity against N. apis spores and that antimicrobial seminal fluid components kill spores in multiple ways. The protein fraction of seminal fluid induces extracellular spore germination, which disrupts the life cycle of N. apis, whereas the non-protein fraction of seminal fluid induces a direct viability loss of intact spores. We conclude that males provide their ejaculates with efficient antimicrobial molecules that are able to kill N. apis spores and thereby reduce the risk of disease transmission during mating. Our findings could be of broader significance to master honeybee diseases in managed honeybee stock in the future. © 2016 The Author(s).

Background Twin studies of veterans and adults suggest that approximately 30–46% of the variance in posttraumatic stress disorder (PTSD) is attributable to genetic factors. The remaining variance is attributable to the non-shared environment, which, by definition, includes combat exposure. This study used a gene by measured environment twin design to examine if the effect of genetic and environmental factors that contribute to the etiology PTSD were dependent on level of combat exposure. Methods The sample was drawn from the Vietnam Era Twin Registry and included 620 male-male twin pairs who served in the U.S. Military in South East Asia during the Vietnam War era. Analyses were based on data from a clinical diagnostic interview of lifetime PTSD symptoms and a self-report measure of combat exposure. Results Biometric modeling revealed that the effect of genetic and non-shared environment factors on PTSD varied as a function of level of combat exposure such that the association between these factors and PTSD was stronger at higher levels of combat exposure. Conclusions Combat exposure may act as a catalyst that augments the impact of hereditary and environmental contributions to PTSD. Individuals with the greatest exposure to combat trauma were at increased risk for PTSD as a function of both genetic and other environmental factors. Additional work is needed to determine the biological and environmental mechanisms driving these associations. PMID:24001428

Quantitative EEG during REM and NREM sleep in combat-exposed veterans with and without Posttraumatic Stress Disorder

Summary Sleep disturbances are a hallmark feature of posttraumatic stress disorder (PTSD), and associated with poor clinical outcomes. Few studies have examined sleep quantitative electroencephalography (qEEG), a technique able to detect subtle differences polysomnography does not capture. We hypothesized greater high-frequency qEEG would reflect “hyperarousal” in in combat veterans with PTSD (n=16) compared to veterans without PTSD (n=13). EEG power in traditional EEG frequency bands was computed for artifact-free sleep epochs across an entire night. Correlations were performed between qEEG and ratings of PTSD symptoms and combat exposure. The groups did not differ significantly in whole night qEEG measures for either REM or NREM. Non-significant medium effect sizes suggest less REM beta (opposite to our hypothesis), less REM and NREM sigma, and more NREM gamma in combat veterans with PTSD. Positive correlations were found between combat exposure and NREM beta (PTSD group only), and REM and NREM sigma (non-PTSD group only). Results did not support global hyperarousal in PTSD as indexed by increased beta qEEG activity. The correlation of sigma activity with combat exposure in those without PTSD, and the non-significant trend towards less sigma activity during both REM and NREM sleep in combat veterans with PTSD suggests that differential information processing during sleep may characterize combat-exposed military veterans with and without PTSD.

When positioned in a combat situation, soldiers may be subjected to extreme stress. However, only a few combat-exposed soldiers develop long-term disturbance, namely, posttraumatic stress disorder (PTSD). This study aimed to explore risk factors for developing PTSD in order to improve the psychiatric screening process of new recruits. In a semiprospective design, we compared 2,362 war veterans who developed PTSD (according to DSM-IV criteria) with an equal number of war veterans who did not develop PTSD. Controls were matched on the basis of sequential army identification numbers, that is, the soldier drafted immediately after the index PTSD veteran (usually on the same day). This method ensured similar demographic variables such as socioeconomic level and education. Data were collected from the Israeli Defense Force database and used in a comprehensive survey conducted between January 2000 and March 2001. Comparisons were made on predrafting personal factors (behavioral assessment, cognitive assessment, linguistic ability, and education) and pretrauma army characteristics (ie, rank and training). Neither behavioral assessment nor training were found to predict PTSD. The predictive factors that were found were essentially nonspecific, such as cognitive functioning, education, rank, and position during the trauma, with little effect from training. In an armed force that uses universal recruitment, carefully structured predrafting psychological assessment of social and individual qualifications (including motivation) failed to identify increased risk factors for PTSD. However, nonspecific factors were found to be associated with an increased risk for PTSD. This study suggests that the focus of future research on risk factors for PTSD should incorporate other domains rather than behavioral assessment alone. clinicaltrials.gov Identifier: NCT00229359.

Obesity, both directly and indirectly, increases the risk for a variety of disease conditions including diabetes, hypertension, liver disease, and certain cancers, which in turn, decreases the overall lifespan in both men and women. Though the cardiovascular risks of obesity are widely acknowledged, less often identified is the relationship between obesity and renal function. Directory of Open Access Journals (DOAJ), Google Scholar, PubMed, EBSCO and Web of Science has been searched. The concept of the "Metabolic Syndrome" helps us to understand this close link between obesity, diabetes, hypertension, and renal dysfunction. An elevated body mass index has shown to be one of the major determinants of glomerular hyperfiltration that lead to the development of chronic kidney disease. Interestingly, weight loss can lead to attenuation of hyperfiltration in severely obese patients suggesting a possible therapeutic option to combat obesity-related hyperfiltration. Various treatment strategies had been suggested to decrease impact of obesity on kidneys. These are blood pressure controling, inhibition of the renin-angiotensinaldosterone axis, improving glycemic control, improving dyslipidemia, improving protein uriaand lifestyle modifications. Regardless of the numerous pharmacotherapies, the focus should be on the root cause: obesity.

Neuroblastoma, a Paradigm for Big Data Science in Pediatric Oncology

Pediatric cancers rarely exhibit recurrent mutational events when compared to most adult cancers. This poses a challenge in understanding how cancers initiate, progress, and metastasize in early childhood. Also, due to limited detected driver mutations, it is difficult to benchmark key genes for drug development. In this review, we use neuroblastoma, a pediatric solid tumor of neural crest origin, as a paradigm for exploring “big data” applications in pediatric oncology. Computational strategies derived from big data science–network- and machine learning-based modeling and drug repositioning—hold the promise of shedding new light on the molecular mechanisms driving neuroblastoma pathogenesis and identifying potential therapeutics to combat this devastating disease. These strategies integrate robust data input, from genomic and transcriptomic studies, clinical data, and in vivo and in vitro experimental models specific to neuroblastoma and other types of cancers that closely mimic its biological characteristics. We discuss contexts in which “big data” and computational approaches, especially network-based modeling, may advance neuroblastoma research, describe currently available data and resources, and propose future models of strategic data collection and analyses for neuroblastoma and other related diseases.

Experiences in teleoperation of land vehicles

Teleoperation of land vehicles allows the removal of the operator from the vehicle to a remote location. This can greatly increase operator safety and comfort in applications such as security patrol or military combat. The cost includes system complexity and reduced system performance. All feedback on vehicle performance and on environmental conditions must pass through sensors, a communications channel, and displays. In particular, this requires vision to be transmitted by close-circuit television with a consequent degradation of information content. Vehicular teleoperation, as a result, places severe demands on the operator. Teleoperated land vehicles have been built and tested by many organizations, including Sandia National Laboratories (SNL). The SNL fleet presently includes eight vehicles of varying capability. These vehicles have been operated using different types of controls, displays, and visual systems. Experimentation studying the effects of vision system characteristics on off-road, remote driving was performed for conditions of fixed camera versus steering-coupled camera and of color versus black and white video display. Additionally, much experience was gained through system demonstrations and hardware development trials. The preliminary experimental findings and the results of the accumulated operational experience are discussed.

A sample of 382 Israeli soldiers who developed combat stress reactions (CSR) during the 1982 Israel-Lebanon War were compared with groups of carefully matched controls who did not develop CSR. Lack of social support from officers was found to be related to greater feelings of loneliness and greater likelihood of CSR in soldiers. Lack of social support from buddies was found to be related to greater loneliness. Intensity of battle was also found to be related to greater feelings of loneliness and increased likelihood of CSR. A path model was tested and supported. The model suggests that battle intensity and officer support lead to CSR directly and indirectly by causing increased feelings of loneliness. Possible cognitive and psychodynamic explanations for the findings are offered. The limitations of making causal statements from retrospective perceptions is discussed.

An automated methodology development. [software design for combat simulation

The design methodology employed in testing the applicability of Ada in large-scale combat simulations is described. Ada was considered as a substitute for FORTRAN to lower life cycle costs and ease the program development efforts. An object-oriented approach was taken, which featured definitions of military targets, the capability of manipulating their condition in real-time, and one-to-one correlation between the object states and real world states. The simulation design process was automated by the problem statement language (PSL)/problem statement analyzer (PSA). The PSL/PSA system accessed the problem data base directly to enhance the code efficiency by, e.g., eliminating non-used subroutines, and provided for automated report generation, besides allowing for functional and interface descriptions. The ways in which the methodology satisfied the responsiveness, reliability, transportability, modifiability, timeliness and efficiency goals are discussed.

Risks to personnel engaged in military operations include not only the threat of enemy firepower but also risks from exposure to other hazards such as radiation. Combatant commanders of the U. S. Army carefully weigh risks of casualties before implementing battlefield actions using an established paradigm that take these risks into consideration. As a result of the inclusion of depleted uranium (DU) anti-armor ammunition in the conventional (non-nuclear) weapons arsenal, the potential for exposure to DU aerosols and its associated chemical and radiological effects becomes an element of the commanders’ risk assessment. The Capstone DU Aerosol Study measured the rangemore » of likely DU oxide aerosol concentrations created inside a combat vehicle perforated with a DU munition, and the Capstone Human Health Risk Assessment (HHRA) estimated the associated doses and calculated risks. This paper focuses on the development of a scientific approach to adapt the risks from DU’s non uniform dose distribution within the body using the current U.S. Department of Defense (DoD) radiation risk management approach. The approach developed equates the Radiation Exposure Status (RES) categories to the estimated radiological risks of DU and makes use of the Capstone-developed Renal Effects Group (REG) as a measure of chemical risk from DU intake. Recommendations are provided for modifying Army guidance and policy in order to better encompass the potential risks from DU aerosol inhalation during military operations.« less

United States military doctrine permits the use of fresh whole blood (FWB), donated by U.S. military personnel on site, for casualties with life-threatening injuries at combat support hospitals. U.S. Military Medical Department policy dictates that all patients treated at military facilities during combat (coalition military personnel, foreign nationals, and enemy combatants) are to be treated equally. The objectives of this study were to describe admission vital signs and laboratory values and injury location for patients transfused with FWB, and to determine if FWB was employed equally among all patient personnel categories at a combat support hospital. This retrospective cohort study evaluated admission vital signs and laboratory values, injury location, and personnel category for all patients receiving FWB at a U.S. Army combat support hospital in Baghdad, Iraq, between January and December 2004. Eighty-seven patients received 545 units of FWB. Upon admission, the average (+/-S.D.) heart rate was 144 bpm (+/-25); systolic blood pressure, 106 mmHg (+/-33); base deficit, 9 (+/-6.5); hemoglobin, 9.0 g/dl (+/-2.6); platelet concentration, 81.9 x 10(3)/mm(3) (+/-81); international normalized ratio (INR), 2.0 (+/-1.1); and temperature 95.7 degrees F (+/-2.6). The percentages of intensive care patients who received FWB by personnel category were as follows: coalition soldiers, 51/592 (8.6%); foreign nationals, 25/347 (7.2%); and enemy combatants, 11/128 (8.5% (p = 0.38). The amount of FWB transfused by personnel category was as follows: coalition soldier, 4 units (1-35); foreign national, 4 units (1-36); and enemy combatant, 4 units (1-11) (p = 0.9). Fresh whole blood was used for anemic, acidemic, hypothermic, coagulopathic patients with life-threatening traumatic injuries in hemorrhagic shock, and it was transfused in equal percentages and amounts for coalition soldiers, foreign nationals, and enemy combatants.

Summary In over a decade of war, numerous advancements have been made to improve overall combat-related mortality, but infectious complications remain a leading cause of both morbidity and mortality in combat-related injured personnel. Here we will attempt to compare the challenges and lessons of combat-related injuries and infections from the Vietnam War with those of OIF/OEF. Throughout the Vietnam War and OIF/OEF, there have been similar infection-related challenges faced in caring for combat-related trauma patients. Both conflicts reinforced the importance of rapid medical evacuation and definitive surgical management of war wounds. They revealed the constant evolution of infecting organisms and the challenge of increasing antimicrobial resistance. We have also seen that with decreased mortality of severely injured personnel new morbidities must be addressed. Using the foundation of fragmented research from the Vietnam War, previously successful models were assembled into joint service research institutions which have allowed these questions to be addressed. However, many questions regarding measures to reduce infectious complications in our combat-injured personnel remain unanswered. Continued research building on established knowledge is critical for continued improvements in the care of combat-related trauma patients. PMID:26406435

To characterize the indirect associations of combat exposure with post-deployment physical symptoms through shared associations with post-traumatic stress disorder (PTSD), depression and insomnia symptoms. Surveys were administered to a sample of U.S. soldiers (N = 587) three months after a 15-month deployment to Iraq. A multiple indirect effects model was used to characterize direct and indirect associations between combat exposure and physical symptoms. Despite a zero-order correlation between combat exposure and physical symptoms, the multiple indirect effects analysis did not provide evidence of a direct association between these variables. Evidence for a significant indirect association of combat exposure and physical symptoms was observed through PTSD, depression, and insomnia symptoms. In fact, 92% of the total effect of combat exposure on physical symptoms scores was indirect. These findings were evident even after adjusting for the physical injury and relevant demographics. This is the first empirical study to suggest that PTSD, depression and insomnia collectively and independently contribute to the association between combat exposure and post-deployment physical symptoms. Limitations, future research directions, and potential policy implications are discussed. Published by Elsevier Inc.
