The Idaho National Laboratory (INL) is managed by Battelle Energy Alliance, LLC (BEA) for the Department of Energy. The INL Protective Security Forces (Pro Force) are involved in training exercises that generate impulse noise by small arms fire. Force-on-force (FOF) training exercises that simulate real world scenarios require the Pro Force to engage the opposition force (OPFOR) while maintaining situational awareness through verbal communications. The Combat Arms earplug was studied to determine if it provides adequate hearing protection in accordance with the requirements of MIL-STD-1474C/D. The Combat Arms earplug uses a design that allows continuous noise through a critical orificemore » while effectively attenuating high-energy impulse noise. The earplug attenuates noise on a non linear scale, as the sound increases the attenuation increases. The INL studied the effectiveness of the Combat Arms earplug with a Bruel & Kjaer (B&K) head and torso simulator used with a selection of small arms to create impulse sound pressures. The Combat Arms earplugs were inserted into the B&K head and torso ears, and small arms were then discharged to generate the impulse noise. The INL analysis of the data indicates that the Combat Arms earplug does provide adequate protection, in accordance with MIL-STD-1474C/D, when used to protect against impulse noise generated by small arms fire using blank ammunition. Impulse noise generated by small arms fire ranged from 135–160 dB range unfiltered un-weighted. The Combat Arms earplug attenuated the sound pressure 10–25 dB depending on the impulse noise pressure. This assessment is consistent with the results of previously published studies on the Combat Arms earplug (see Section 5, “References”). Based upon these result, the INL intends to use the Combat Arms earplug for FOF training exercises.« less

The purpose of this study was to assess normal hearing listeners' performance in detecting a stationary backup alarm signal and to quantify the linear distance at detection point. Detection distances for 12 participants with normal hearing were measured while they were fitted with 7 hearing protectors and while they were unoccluded (open ear). A standard (narrowband) backup alarm signal and a broadband (pulsed white noise) backup alarm signal from Brigade[1] were used. The method of limits, with distance as the physical measurement variable and threshold detection as the task, was employed to find at which distance the participant could first detect the backup alarms. A within-subject Analysis of Variance (ANOVA) revealed a significant main effect of the listening conditions on the detection distance in feet. Post hoc analyses indicated that the Bilsom L3HV conventional passive earmuff (at 1132.2 ft detection distance) was significantly poorer compared to all other HPDs and the open ear in detection distance achieved, and that there were no statistically-significant differences between the unoccluded ear (1652.3 ft), EB-15-Lo BlastPLGTM (1546.2 ft), EB-15-Hi BlastPLGTM (1543.4 ft), E-A-R/3M Combat ArmsTM earplug-nonlinear, level-dependent state (1507.8 ft), E-A-R/3M HiFiTM earplug (1497.7 ft), and Bilsom ImpactTM dichotic electronic earmuff (1567.2 ft). In addition, the E-A-R/3M Combat ArmsTM earplug-passive steady state resulted in significantly longer detection distances than only the open ear condition, at 1474.1 ft versus 1652.3 ft for the open ear. ANOVA also revealed a significant main effect of the backup alarm type on detection distance. The means were 1600.9 ft for the standard (narrowband) backup alarm signal, and a significantly closer 1379.4 ft was required for the Brigade broadband backup alarm signal. For on-ground workers, it is crucial to detect backup alarm signals as far away as possible rather than at close distances since this will provide them more time to react to approaching vehicles. The results of this study suggest that as the attenuation of the hearing protectors increases, precautions should be considered by safety professionals. This is because, as it was the case with the Bilsom passive earmuff and E-A-R/3M Combat ArmsTM earplug-passive steady state, high attenuation minimizes the detection distance and as a result on-foot workers will have less time to react to any approaching vehicle. The main effects of the type of backup alarm signal demonstrated a statistically-significant advantage of the standard backup alarm over the broadband backup alarm on detection distance in feet. The magnitude of the improvement produced by the standard backup alarm was 221.5 feet, a very large margin. For example, with a vehicle backing at 10 mph, the 221.5 ft decrease in detection distance with the Brigade alarm equates to the vehicle arriving 15 seconds sooner at the worker from the point at which its alarm was first heard.

Impulse peak insertion loss (IPIL) was studied with two acoustic test fixtures and four hearing protector conditions at the E-A-RCAL Laboratory. IPIL is the difference between the maximum estimated pressure for the open-ear condition and the maximum pressure measured when a hearing protector is placed on an acoustic test fixture (ATF). Two models of an ATF manufactured by the French-German Research Institute of Saint-Louis (ISL) were evaluated with high-level acoustic impulses created by an acoustic shock tube at levels of 134 decibels (dB), 150 dB, and 168 dB. The fixtures were identical except that the E-A-RCAL ISL fixture had ear canals that were 3 mm longer than the National Institute for Occupational Safety and Health (NIOSH) ISL fixture. Four hearing protection conditions were tested: Combat Arms earplug with the valve open, ETYPlugs® earplug, TacticalPro headset, and a dual-protector ETYPlugs earplug with TacticalPro earmuff. The IPILs measured for the E-A-RCAL fixture were 1.4 dB greater than the National Institute for Occupational Safety and Health (NIOSH) ISL ATF. For the E-A-RCAL ISL ATF, the left ear IPIL was 2.0 dB greater than the right ear IPIL. For the NIOSH ATF, the right ear IPIL was 0.3 dB greater than the left ear IPIL. PMID:26356380

Improvised explosive devices and mines pose a formidable threat to military convoys traveling in Iraq. This study evaluated battle injuries sustained by a mechanized battalion operating against this threat. The objective was to gain insight into injury profiles and prevention. In the period examined, 32 attacks injured 120 Marines, causing 188 injuries. Upper extremity and head injuries (70%) were common, whereas lower extremity injuries (11%) were rare (as expected, given the threat and the body areas exposed). Shoulder and axilla protectors may be beneficial, but lower arm and hand injuries remain difficult to combat. Ear injury was the most common single injury type (23%). Combat earplugs may reduce ear blast injuries. Eye injuries were uncommon (0.5%), likely because of ballistic eye protection. Injury to the torso (11%) was generally mild, because of body armor vests. The majority of wounds were minor, allowing > 80% of the injured Marines to return to duty.

To design a test battery and conduct a proof-of-concept experiment of a test method that can be used to measure the detection performance afforded by military advanced hearing protection devices (HPDs) and tactical communication and protective systems (TCAPS). The detection test was conducted with each of the four loudspeakers located at front, right, rear and left of the participant. Participants wore 2 in-ear-type TCAPS, 1 earmuff-type TCAPS, a passive Combat Arms Earplug in its "open" or pass-through setting and an EB-15LE™ electronic earplug. Devices with electronic gain systems were tested under two gain settings: "unity" and "max". Testing without any device (open ear) was conducted as a control. Ten participants with audiometric requirements of 25 dBHL or better at 500, 1000, 2000, 4000, 8000 Hz in both ears. Detection task performance varied with different signals and speaker locations. The test identified performance differences among certain TCAPS and protectors, and the open ear. A computer-controlled detection subtest of the Detection-Recognition/Identification-Localisation-Communication (DRILCOM) test battery was designed and implemented. Tested in a proof-of-concept experiment, it showed statistically-significant sensitivity to device differences in detection effects with the small sample of participants (10). This result has important implications for selection and deployment of TCAPS and HPDs on soldiers and workers in dynamic situations.

To investigate the effect of controlled low-speed wind-noise on the auditory situation awareness performance afforded by military hearing protection/enhancement devices (HPED) and tactical communication and protective systems (TCAPS). Recognition/identification and pass-through communications tasks were separately conducted under three wind conditions (0, 5, and 10 mph). Subjects wore two in-ear-type TCAPS, one earmuff-type TCAPS, a Combat Arms Earplug in its 'open' or pass-through setting, and an EB-15LE electronic earplug. Devices with electronic gain systems were tested under two gain settings: 'unity' and 'max'. Testing without any device (open ear) was conducted as a control. Ten subjects were recruited from the student population at Virginia Tech. Audiometric requirements were 25 dBHL or better at 500, 1000, 2000, 4000, and 8000 Hz in both ears. Performance on the interaction of communication task-by-device was significantly different only in 0 mph wind speed. The between-device performance differences varied with azimuthal speaker locations. It is evident from this study that stable (non-gusting) wind speeds up to 10 mph did not significantly degrade recognition/identification task performance and pass-through communication performance of the group of HPEDs and TCAPS tested. However, the various devices performed differently as the test sound signal speaker location was varied and it appears that physical as well as electronic features may have contributed to this directional result.
Hearing protection for clubbers is music to their ears.

while it is difficult to promote the use of hearing protectors in noisy workplaces and leisure settings, some nightclub attendees choose to wear earplugs when exposed to loud music. This qualitative study investigated the perceptions of clubbers about the advantages and disadvantages of earplug use in nightclubs. Such first-hand information could potentially be used to educate non-wearers about the features of different earplug types, the experience of wearing earplugs and their relative merits. structured telephone interviews were conducted with 20 regular clubbers who wear different types of earplugs at nightclubs. Participants were asked about their experience of wearing earplugs and, in particular, what they perceive to be the advantages and disadvantages of earplugs. participants' responses revealed that cheaper foam earplugs are considered less satisfactory than more expensive earplugs, which are relatively discreet and comfortable, facilitate communication with others, create minimal music distortion and, in some cases, improve music sound quality. In terms of effectiveness, all types of earplugs were considered beneficial in reducing the after-effects of loud music and providing hearing protection. the perceived advantages of earplugs, which are often not recognised by non-earplug wearers, should be communicated in order to encourage the use of earplugs among clubbers.
An evaluation of musician earplugs with college music students.

Musician earplugs are marketed and recommended for use in music settings but no studies have evaluated these products with musicians. This study evaluated the influences of earplugs on college students' perception and abilities to communicate in a musical environment, attitudes of earplugs, comfort over time, and the influence of earplugs on ability to play music. College students (N = 323) were provided with earplugs for use during and following an experimental condition designed to mimic a night club. Results underline the challenges of earplugs in environments that are both loud and require verbal interaction. Responses to comfort questions were variable and suggest a multi-factorial set of influences that may include intrinsic variables. Despite these limitations, subjects in this study generally liked the earplugs and believed that they are valuable. However, the earplugs were not viewed favorably by musicians willing to use the earplugs while playing music. This study supports the view that earplugs are subject to many problems and should be considered as a last resort.
Pressure-equalizing earplugs do not prevent barotrauma on descent from 8000 ft cabin altitude.

The aim of this study was to evaluate the effect of pressure-equalizing earplugs available in major airports and drugstores. No previous study has focused on preventing barotrauma using these earplugs. Blinded and double-blinded, one type of pressure-equalizing earplugs (JetEars) was studied in 27 volunteers disposed to ear barotrauma. They acted as their own controls with an active earplug in one ear and a placebo earplug in the other ear at random. All were exposed to the same well-defined pressure profile for 1 h at 8000 ft, comparable to the environment in civil commercial air travel in a pressurized cabin. Satisfaction was assessed by questionnaire and objective results were evaluated prior to and after the pressure exposure by tympanometry and otoscopy using the Teed classification. The majority of the volunteers (78%) reported a pleasant noise-reducing feeling using the earplugs. However, 75% also experienced ear pain during descent. In comparing the middle ear pressure before and after pressurization, a decrease was found in ears with both active earplugs and placebo earplugs. No difference between the active and the placebo earplugs were found. Furthermore, after evaluation of the two groups of ears using otoscopy, no prevention of barotrauma was found. In fact, the ears using an active pressure-equalizing earplug scored significantly worse (p = 0.033). Feelings of noise reduction were reported, but no prevention of barotrauma could be demonstrated with the use of pressure-equalizing earplugs. Pressure-equalizing earplugs cannot be recommended in air travel for preventing ear barotrauma.

Musicians are at risk of hearing loss from sound exposure, and earplugs form part of many musicians' hearing conservation practices. Although musicians typically report a range of difficulties when wearing earplugs, there are many who have managed to successfully incorporate earplugs into their practice of music. The study aim was to provide a detailed account of earplug usage from the perspective of the musician, including motivating factors, practical strategies, and attitudes. In-depth interviews with 23 musicians were transcribed and content analysis was performed. Responses were coded and classified into three main themes: advantages, disadvantages, and usage patterns and strategies, together with an overlapping fourth theme, youth perspectives. Several positive aspects of wearing earplugs were identified, including long-term hearing protection and reduced levels of fatigue and pain. Musicians reported that earplugs present few problems for communication, improve sound clarity in ensembles, are discreet, and are easy to handle. However, earplugs also present challenges, including an overall dullness of sound, reduced immediacy, and an impaired ability to judge balance and intonation due to the occlusion effect, all of which influence usage habits and patterns. The experiences of the younger musicians and long-term users of earplugs indicate that practice, persistence, and a flexible approach are required for successful earplug usage. In time, there may be greater acceptance of earplugs, particularly amongst a new generation of musicians, some of whom regard the earplugs as a performance enhancement tool as well as a protective device.
Providing earplugs to young adults at risk encourages protective behaviour in music venues.
Beach, Elizabeth Francis; Nielsen, Lillian; Gilliver, Megan

For some young people, nightclubs and other music venues are a major source of noise exposure, arising from a combination of very high noise levels; relatively long attendance duration; and frequent, sustained participation over several years. Responsibility for hearing protection is largely left to individuals, many of whom choose not to wear earplugs. In order to encourage earplug use in these settings, a new approach is needed. The aim of the study was to examine whether presentation of hearing health information would result in increased use of earplugs, or whether provision of earplugs alone would be sufficient to change behaviour. A total of 51 regular patrons of music venues were allocated to either a low-information (lo-info) or high-information (hi-info) group. Both groups completed a survey about their current noise exposure, earplug usage and perceived risk of hearing damage. Both groups were also provided with one-size-fits-all filtered music earplugs. The hi-info group was also provided with audio-visual and written information about the risks of excessive noise exposure. After 4 weeks, and again after an additional 12 weeks, participants were asked about their recent earplug usage, intention to use earplugs in the future, and perceived risk of hearing damage. The results showed that after 4 weeks, the hi-info group's perceived personal risk of hearing damage was significantly higher than that of the lo-info group. After 16 weeks, these differences were no longer evident; however, at both 4 and 16 weeks, both the lo- and hi-info groups were using the earplugs equally often; and both groups intended to use earplugs significantly more often in the future. This suggests that the information was unnecessary to motivate behavioural change. Rather, the simple act of providing access to earplugs appears to have effectively encouraged young at-risk adults to increase their earplug use. © The Author(s) 2015.

The Effects of Musician's Earplugs on Acoustic and Perceptual Measures of Choral and Solo Sound.
Cook-Cunningham, Sheri L
2017-10-25
The purpose of this investigation was to assess the effects of earplugs on acoustical and perceptual measures of choral and solo sound. The researcher tested the effects of musician's earplugs on choral and solo timbre and singer perceptions. Members of an intact women's university choir recorded Dona Nobis Pacem under two conditions, no earplugs and with earplugs over time. Approximately half of the choir members also participated as soloists, recording Over the Rainbow under the same two conditions. All recordings were analyzed using long-term average spectra (LTAS). After participating in each recording session, the participants responded to a questionnaire about ability to hear self (solo and choral context) and ability to hear others (choral context) under two conditions, no earplugs and with earplugs. LTAS results revealed that wearing earplugs in a choral setting caused decreased mean signal energy (>1 dB), resulting in less resonant singing. LTAS results also indicated that wearing earplugs in a solo setting had less effect on mean signal energy, resulting in a mean difference <1 dB in 3 of the 4 weeks studied. Singer questionnaire responses showed that wearing earplugs had a greater effect on participants' ability to hear others than it did on their ability to hear themselves. In the context of this study, it seems that wearing earplugs had more effect on timbre and the ability to receive sufficient auditory feedback in a choral setting than it did in a solo setting. Findings from this study could provide important information when structuring hearing conservation strategies. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

To determine the prevalence of hearing protection use among attendees of Rock and Roll concerts at baseline and in concerts where earplugs are provided for free at concert venue entrances. Six concerts performed at two music venues in Toronto, Canada were evaluated. Study personnel observed and recorded the use of hearing protection at three concerts where no earplugs were distributed, and three concerts where earplugs were provided for free at the concert venue entrance. A total of 955 individuals over the age of 18 were observed at six concerts. Six hundred and thirty-seven individuals (64% male) were observed at concerts where no earplugs were provided, and 318 individuals (68% male) were observed at concerts where free earplugs were provided. Multivariate logistic regression demonstrated a significant increase in hearing protection usage at concerts where earplugs were provided for free at the concert venue entrance, odds ratio 7.27 (95% CI: 3.24-16.30). The provision of free earplugs at concert venues may be a simple and inexpensive intervention that could be a component of a larger public health campaign to prevent non-occupational noise-induced hearing loss.

Identifying the Optimal Water-Occluding Earplugs: A Scientific Simulation Study.
Kovoor, Joshua; Al Hussaini, Ali; Backhouse, Steven

Numerous types of water-occluding earplugs are available as a means of preventing infection in patients with external and middle ear disease. However, little is known about the comparative efficacies of these earplugs with prolonged water exposure. In this study, we assessed the water impermeability of various earplug materials to prolonged water exposure. Nine earplugs were tested: cotton wool mixed with petroleum jelly, cotton wool externally coated with petroleum jelly, Blu-Tack, foam earplugs, silicone putty, silicone earplugs, flanged earplugs, and hard and soft silicone custom-moulds. Precision-engineered cups were filled with 30 mL water and sealed with lids that contained a 10 mm diameter hole to simulate the ear canal. The aperture was occluded with different earplugs, and the cup was inverted. Computer software was used to record the water loss to the nearest 10 milligrams 720 times over a three-hour period. The test was repeated five times for each material. The water permeability onset, rate, and total amount of water loss varied markedly between the materials; cotton wool mixed with petroleum jelly demonstrated the fastest onset of leak and the highest rate of water loss (p < 0.00001), as well as the largest amount of cumulative water loss (p = 0.00213). The soft silicone custom-mould plugs, hard silicone custom-mould plugs, foam plugs, and silicone putty demonstrated no leaks. This study demonstrates a wide range of water permeabilities of commonly used ear-occluding materials during prolonged water exposure. We found that the generally suggested regimen of cotton wool mixed with petroleum jelly may be inefficacious for substantial periods of water exposure.

A systematic review and meta-analysis to assess the efficacy of earplugs as an ICU strategy for reducing delirium. MEDLINE, EMBASE, and the Cochrane Central Register of controlled trials were searched using the terms "intensive care," "critical care," "earplugs," "sleep," "sleep disorders," and "delirium." Intervention studies (randomized or nonrandomized) assessing the efficacy of earplugs as a sleep hygiene strategy in patients admitted to a critical care environment were included. Studies were excluded if they included only healthy volunteers, did not report any outcomes of interest, did not contain an intervention group of interest, were crossover studies, or were only published in abstract form. Nine studies published between 2009 and 2015, including 1,455 participants, fulfilled the eligibility criteria and were included in the systematic review. Studies included earplugs as an isolated intervention (n = 3), or as part of a bundle with eye shades (n = 2), or earplugs, eye shades, and additional sleep noise abatement strategies (n = 4). The risk of bias was high for all studies. Five studies comprising 832 participants reported incident delirium. Earplug placement was associated with a relative risk of delirium of 0.59 (95% CI, 0.44-0.78) and no significant heterogeneity between the studies (I, 39%; p = 0.16). Hospital mortality was reported in four studies (n = 481) and was associated with a relative risk of 0.77 (95% CI, 0.54-1.11; I, 0%; p < 0.001). Compliance with the placement of earplugs was reported in six studies (n = 681). The mean per-patient noncompliance was 13.1% (95% CI, 7.8-25.4) of those assigned to receive earplugs. Placement of earplugs in patients admitted to the ICU, either in isolation or as part of a bundle of sleep hygiene improvement, is associated with a significant reduction in risk of delirium. The potential effect of cointerventions and the optimal strategy for improving sleep hygiene and associated effect on patient-centered outcomes remains uncertain.

To determine whether very low birth weight (VLBW) newborns (<1500 g) wearing silicone earplugs grow larger and perform better on developmental exams than controls. VLBW newborns (n=34) were randomized to wearing earplugs or not. Hospital outcomes were abstracted from medical charts by research staff masked to intervention status. Fourteen extremely low birth weight (ELBW) newborns (<1000 g) were also evaluated at 18 to 22 months. After adjusting for birth weight, 11 surviving newborns in the earplug group were 225 g (95% CI: 45, 405) heavier at 34 weeks post menstrual age than the 13 controls. Six ELBW earplug infants scored 15.53 points (95% CI: 3.03, 28.02) higher than six controls on the Bayley Mental Development Index. Their head circumferences were 2.59 cm (95% CI: 0.97, 4.21) larger. Earplugs may facilitate weight gain in VLBW newborns. Better outcomes may persist at 18 to 22 months at least in ELBW infants.

Hearing loss prevention has always been an important issue for audiologists. The importance of hearing loss prevention education for young musicians is now recognized by the National Association for Music Education as well as the National Association of Schools of Music. Adopt-a-Band is a commercial program designed to foster hearing loss prevention behavior in young musicians. This study assessed changes in earplug use, measured using self-report surveys, after Adopt-a-Band training. Participants were members of 2 high school marching bands who viewed an informational DVD and reviewed fact sheets. Flat-attenuation earplugs were distributed, and training was provided. In addition, study participants engaged in discussion of hearing loss with a doctor of audiology student. Before training, 23% of participants reported they had previously used hearing protection. Immediately after training, 94% of participants reported they planned to use hearing protection at least occasionally. In a final end-of-season survey, earplug use had reliably increased; 62% of participants reported they used earplugs at least occasionally. Earplug use increased, but self-reported behavioral change was not as robust as predicted from self-reported participant intentions. Participant comments regarding factors that influenced their earplug use decisions suggest opportunities to improve training.
An objective comparison of leakage between commonly used earplugs.
Alt, Jeremiah A; Collins, William O

We sought to determine the efficacy of commonly used earplugs using an anatomically correct ear model. The total volume and rate of water that leaked past the earplug and subsequent defect in the tympanic membrane over separately measured 30, 60, 120, and 180-second intervals were recorded. Scenarios tested included a control with no earplug, custom molded earplug (Precision Laboratories, Orlando, FL), Mack's plug (Warren, MI), Doc's plug (Santa Cruz, CA), and cotton balls coated with petroleum jelly. All plugs tested resulted in less leakage at all time points when compared with no plug (P < .05). At 30 seconds, the custom molded, Mack's and Doc's plugs all showed significantly less leakage when compared with the cotton ball coated with petroleum jelly (P < .05). At 60, 120, and 180 seconds, Mack's, Doc's, and the cotton plugs all showed significantly less leakage compared with the customized plug (P < .05). At 120 and 180 seconds, Mack's plugs had significant less leakage than the cotton plug (P < .05). Among the types of plugs, the molded variety (Mack's) showed the least volume and lowest leakage rate (f(4,45) = 94 [P < .001]). In addition, Doc's and cotton balls coated with petroleum jelly were more effective than the customized earplugs. If the clinician feels that middle ear and external canal water exposure should be minimized, then use of earplugs, particularly the moldable variety, merits further consideration.

Approaches were examined for reducing acoustic noise levels heard by subjects during functional magnetic resonance imaging (fMRI), a technique for localizing brain activation in humans. Specifically, it was examined whether a device for isolating the head and ear canal from sound (a “helmet”) could add to the isolation provided by conventional hearing protection devices (i.e., earmuffs and earplugs). Both subjective attenuation (the difference in hearing threshold with versus without isolation devices in place) and objective attenuation (difference in ear-canal sound pressure) were measured. In the frequency range of the most intense fMRI noise (1–1.4 kHz), a helmet, earmuffs, and earplugs used together attenuated perceived sound by 55–63 dB, whereas the attenuation provided by the conventional devices alone was substantially less: 30–37 dB for earmuffs, 25–28 dB for earplugs, and 39–41 dB for earmuffs and earplugs used together. The data enabled the clarification of the relative importance of ear canal, head, and body conduction routes to the cochlea under different conditions: At low frequencies (≤500 Hz), the ear canal was the dominant route of sound conduction to the cochlea for all of the device combinations considered. At higher frequencies (>500 Hz), the ear canal was the dominant route when either earmuffs or earplugs were worn. However, the dominant route of sound conduction was through the head when both earmuffs and earplugs were worn, through both ear canal and body when a helmet and earmuffs were worn, and through the body when a helmet, earmuffs, and earplugs were worn. It is estimated that a helmet, earmuffs, and earplugs together will reduce the most intense fMRI noise levels experienced by a subject to 60–65 dB SPL. Even greater reductions in noise should be achievable by isolating the body from the surrounding noise field. PMID:11206150

Exposure to armed conflict produces biological adaptations oriented to handle the highly stressful conditions in war environments. The special features of The Colombian armed create a special scenario to evaluate the human behavior. In this study, psychiatric, cognitive and emotional processing characteristics of a group of Colombian armed illegal forces of ex-combatants are described. Sixty-three ex combatants and 22 controls were assessed with WAIS (IQ), INECO frontal screening (executive functions), Interpersonal Reactivity Index (empathy), emotional features recognition and MINI (psychiatric profile). When compared to the control group, ex-combatants showed higher frequency of antisocial personality disorder (P=.031) and behavioral dissocial disorder (P=.017). In cognitive profile, the ex-combatants showed a lower score in the executive function test (Me=18.50; RQ=4.00), control (Me=23.00; RQ=5.25), with a poor personal distress in emphatic profile (Me=10.00; RQ=5.00) compared to control group (Me=37.00; RQ=7.25). We found differences in cognitive and psychiatric profile in ex-combatants in comparison with controls. Copyright © 2015 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España.

Reconstructing Lifetime Chemical Profiles of Baleen Whales Using Earplugs: A Century of Stress

The usefulness of an animal as an ecosystem model or sentinel is contingent upon their ecological diversity and the variability inherent in their ecosystem. Marine mammals rely on healthy marine ecosystems for their survival and are uniquely suited to reflect ecosystem variability and degradation. Therefore, they are prime sentinels of marine ecosystem change. Typically used as a measure of aging in cetaceans (order Mysticeti), earplugs can produce alternating dark and light lamina and remain undisturbed during the lifetime of the animal. An earplug is a keratin and lipid matrix in the auditory meatus of mysticetes whales that appears to increase with age. While the literature on earwax plug ageing has often used vague and inconsistent terminology, Roe (1968) clearly established the link between mysticete migration patterns and lamina formation by examining the most recently formed lamina in fin whale earplugs collected in all months of the year, finding a high fat content and keratinized epithelial. Thus, earplugs may provide an excellent repository of lipophilic substances (hormones) and chemicals. Earplugs collected from museum holdings have been analyzed for chemical profiles revealing unprecedented information on stress hormones from as early as the 1870s through present day. For example, a bowhead whale earplug collected in 2013 and aged at 65 years revealed cortisol lifetime profiles (mean, 1.6 ± 5.0 ng/g; range; 0.1-40.0 ng/g) with the largest peaks corresponding to age 13 and 19 (c. 1961 and 1967). Cortisol levels returned to baseline throughout life with increased deviation from baseline occurring post 1990s. Pregnancy hormones revealed approximately 12 possible pregnancy/birth events with an interval mean of 3.8 years (progesterone mean, 3.5 ± 1.7 ng/g; estradiol mean 0.9 ± 0.8 ng/g). The use of a whale earplug to reconstruct lifetime chemical profiles will allow for a more comprehensive examination of stress, development, and contaminant exposure, as well as improve the assessment of response from contaminant use/emission, environmental noise, ship traffic, and climate change on these important marine sentinels.

Eastern DRC has been the site of a protracted conflict in which sexual violence has been a defining feature. The method used was a retrospective registry-based study of sexual violence survivors presenting to Panzi Hospital between 2004 and 2008. This analysis aimed to describe the patterns of sexual violence described by survivors and to analyze perpetrator profiles. As regards results, a total of 4,311 records were analyzed. Perpetrators in this data set were identified as follows: (a) 6% were civilians; (b) 52% were armed combatants; and (c) 42% were simply identified as "assailant(s)" with no further identifying information. Those identified simply as "assailants" perpetrated patterns of sexual violence that were similar to those of armed combatants, suggesting that this group included a large number of armed combatants. Civilian assailants perpetrated a pattern of sexual violence that was distinct from armed combatants. Conclusions are as follows: These data suggest that a high proportion of sexual assaults in South Kivu are perpetrated by armed combatants. Protection of women in South Kivu will require new strategies that take into account the unique nature of sexual violence in DRC. Engaging with local communities, the UN and other aid organizations is necessary to create new context-appropriate protection programs.

To date, factors associated with noise-induced hearing loss at music festivals have not yet been analyzed in a single comprehensive data set. In addition, little is known about the hearing loss-associated behavior of music festival attendees. To assess which factors are associated with the occurrence of a temporary threshold shift (TTS) after music exposure and to investigate the behavior of music festival attendees. This prospective post hoc analysis gathered data from a randomized, single-blind clinical trial conducted on September 5, 2015, at an outdoor music festival in Amsterdam, the Netherlands. Adult volunteers with normal hearing were recruited via social media from August 26 through September 3, 2015. Intention to use earplugs was an exclusion criterion. Of 86 volunteers assessed, 51 were included. This post hoc analysis was performed from October 3, 2016, through February 27, 2017. Music festival visit for 4.5 hours. The primary outcome was a TTS on a standard audiogram for the frequencies 3.0- and 4.0-kHz. Multivariable linear regression was performed to determine which factors are associated with a TTS. A questionnaire on behavior, hearing, and tinnitus was distributed to the participants before and after the festival visit. A total of 51 participants were included (18 men [35%] and 33 women [65%]) with a mean (SD) age of 27 (6) years. Mean (SD) threshold change across 3.0 and 4.0 kHz was 5.4 (5.7) dB for the right ear and 4.0 (6.1) dB for the left ear. Earplug use (absolute difference in the left ear, -6.0 dB [95% CI, -8.7 to -3.2 dB]; in the right ear, -6.4 dB [95% CI, -8.8 to -4.1 dB]), quantity of alcohol use (absolute difference per unit in the left ear, 1.1 dB [95% CI, 0.5 to 1.7 dB]; in the right ear, 0.7 dB [95% CI, 0.1 to 1.4 dB]), drug use (absolute difference in the right ear, 6.0 dB [95% CI, 0.9 to 11.1 dB]), and male sex (absolute difference in the right ear, 4.1 dB [95% CI, 0.3 to 5.9 dB]) were independently associated with hearing loss, with earplug use being the most important factor. Unprotected participants reported significantly worse subjective hearing performance and tinnitus after the festival visit than did participants using earplugs (Cramer V, 0.62 [95% CI, 0.47-0.79] and 0.39 [95% CI, 0.16-0.62], respectively). In the earplug group, the perceived loudness (r = -0.72; 95% CI, -1.00 to -0.43) and appreciation (r = 0.53; 95% CI, 0.29 to 0.78) of music and speech perception (r = 0.21; 95% CI, 0.09 to 0.35) were correlated with the duration of earplug use. The present study identified nonuse of earplugs, use of alcohol and drugs, and male sex as associated with a TTS at an outdoor music festival. Physicians should consider these factors to raise awareness about the combined risk of attending music festivals without using earplugs while consuming alcohol and/or drugs. The intention to use earplugs was correlated with the loudness and appreciation of music with earplugs, which may advocate for the use of personalized earplugs. trialregister.nl Identifier: NTR5401.

Use of hearing protection devices (HPDs) has become necessary when other control measures cannot reduce noise to a safe and standard level. In most countries, more effective hearing protection devices are in demand. The aim of this study was to examine the effects of titanium dioxide (TiO 2 ) nanoparticles on noise reduction efficiency in a polyvinyl chloride (PVC) earplug. An S-60 type PVC polymer as main matrix and TiO 2 with 30 nm size were used. PVC/TiO 2 nanocomposite was mixed at a temperature of 160 °C and 40 rounds per minute (rpm) and the samples were prepared with 0, 0.2 and 0.5 wt% of TiO 2 nanoparticle concentrations. Earplug samples with PVC/TiO 2 (0.2, 0.5 wt%) nanoparticles, when compared with raw earplugs, showed almost equal noise attenuation at low frequencies (500- 125 Hz). However, at high frequencies (2-8 kHz), the power of noise reduction of earplugs containing TiO 2 nanoparticles was significantly increased. The results of the present study showed that samples containing nanoparticles of TiO 2 had more noticeable noise reduction abilities at higher frequencies in comparison with samples without the nanoparticles.
Musician earplugs: Appreciation and protection

Recreational music exposure is a potential risk factor for noise-induced hearing loss (NIHL). Augmented hearing protectors have been designed with modified attenuation characteristics to combine hearing protection and listening comfort. However, to date, only a few independent studies have assessed the performance of those augmented protectors in realistic exposure conditions. This study compares the listening experience and temporary effects on cochlear status with different types of earplugs after exposure to contemporary club music. Five different types of commercially available hearing protectors were worn, all commonly used during leisure-time music exposure. Four of them were augmented premolded earplugs and the fifth type was an inexpensive, standard earplug frequently distributed for free at music events. During five different test sessions of 30 min each, participants not professionally involved in music wore one particular type of protector. Contemporary club music was played at sound pressure levels (SPLs) representative of concerts and bars. After each listening session, a questionnaire on sound quality and general appreciation was completed. In addition, otoacoustic emissions (OAEs) were measured directly before and after music exposure. The reported appreciation clearly differed depending on the addressed characteristics and the specific earplug type. In this test group, the reported appreciation mainly depended on comfort and looks, while differences in sound quality were less noticeable. The changes in OAE amplitude before and after noise exposure were small in terms of clinical standards. Nevertheless, the observed temporary shifts differed systematically for the different types of hearing protectors, with two types of musician earplug showing a more systematic decline than the others. Further research with respect to actual use and achieved protection for real, unsupervised music exposure is warranted. PMID:26168950

Many workers are exposed to noise levels high enough to put them at risk of losing their hearing. However, noise reduction at the source, when technically feasible, is often difficult to implement for economical reasons. Therefore, individual hearing protection remains the most widespread solution in practice. Unfortunately, the hearing protectors currently available on the market are seldom worn continuously as they should be (because they are not very comfortable or must be removed to communicate) and do not match the worker's need for protection (because their actual attenuation is generally unknown). This doctorate thesis work, carried out in close collaboration with SONOMAX HEARING HEALTHCARE I NC., had the general objective to develop a smart earplug that would solve the problems associated with current hearing protection devices thereby effectively preventing noise induced hearing loss in the industrial environment. The issues associated to this development have been formulated in details under the Health and Safety aspect (non-continuous wearing of the hearing protector and un-adapted protection), technical aspects (development of an earplug that is comfortable both from the physical and sound perception points of view and whose performances are measurable) and scientific aspects (modeling of physical systems, signal processing, instrumentation and measurement techniques). The technical developments have resulted in a custom earplug that is instantly fitted to the wearer's ear by silicone injection. Its acoustical performance can be measured using a microphone probe while the attenuation can be adapted to the user's need by the insertion through the earplug of passive acoustical filters. The scientific developments have resulted in the prediction of the attenuation of the earplug from the Noise Reduction measurement and in the prediction of the filtered earplug attenuation.

[Management of war orthopaedic injuries in recent armed conflicts].
Frank, M; Mathieu, L
2013-01-01
The extremities continue to be the most frequent sites of wounding during armed conflicts despite the change of combat tactics, soldier armour and battlefield medical support. Due to the advances in prehospital care and timely transport to the hospital, orthopaedic surgeons deal with severe and challenging injuries of the limbs. In contrast to civilian extremity trauma, the most combat-related injuries are open wounds that often have infection-related complications. Data from two recent large armed conflicts (Iraq, Afghanistan) show that extremity injuries are associated with a high complication rate, morbidity and healthcare utilization. A systematic approach that consists of sequential surgical care and good transport capabilities can reduce the complication rate of these injuries. New medical technologies have been implemented in the treatment strategy during the last decade. This article reviews the published scientific data and current opinions on combat-related extremity injuries. Key words: extremity, combat, trauma, medical support system.
Noise attenuation characteristics of a foam type earplug measured using a dummy head.

The attenuation characteristics of the earplug using a dummy head (KEMAR; Knowles Electronics Manikin for Acoustic Research) were measured, when it was exposed to pure tones or broadband noises at three different sound pressure levels (SPLs) of 70, 80 and 90 dB SPL in the 'wide frequency range from 250 to 20 k Hz. We ascertained the satisfactory capacity of noise attenuation except for from 10 k to 14 k Hz. The noise attenuation level increased with frequency until 2 k Hz, became almost constant until 8 k Hz, then decreased at around 10 k to 14 k Hz, and recovered in the range from 16 k to 20 k Hz. The frequency characteristics were identical among three different sound pressure levels and almost identical between pure tones and broadband noises. The change of frequency characteristics affected by the depth of the earplug that was inserted into the artificial ear canal of the KEMAR was also investigated. Measured sound pressure level by the builetin microphone in the KEMAR revealed a region in which the measured sound pressure levels were relatively higher around 10 k Hz. The frequency of the region moved higher when the earplug was inserted more deeply. Therefore it was considered that this phenomenon was related to the resonance frequency of the cylinder-like cavity made between the end section of the earplug and the diaphragm of the built-in microphone.

Accidents with small arms and munitions during deployment is a significant safety concern for leaders and safety specialists in combat units. Operational stress may lead to forms of unacceptable risk taking with small arms that may underlie some of these accidents. The present research studied the correlation between two dimensions of operational stress, two forms of risk taking with small arms among combat unit soldiers and possible mediators. The dimensions of operational threat, negative affect and personality profile from the EPQ-R-S were predictors; "exaggerated preparedness" and "risky games with small arms and munitions" were dependent variables; safety climate of the platoon served as a mediator variable. The participants were 461 compulsory service combat soldiers in 31 companies. This field study was conducted during period of top security alert. The results reveal that perceived threat is indeed correlated with exaggerated operational preparedness whereas general emotional state was correlated with risky games with small arms. Safety climate mediated only the correlation between general emotional state and risky games with small arms and munitions. Preparedness and risky games were predicted by the interaction of Psychoticism and the Lie Scale from the EPQ-R-S. The results may enhance the efforts in reducing risk taking and prevention of accidents with small arms and munitions during and following deployment.

Sustained Perceptual Deficits from Transient Sensory Deprivation
Sanes, Dan H.
2015-01-01
Sensory pathways display heightened plasticity during development, yet the perceptual consequences of early experience are generally assessed in adulthood. This approach does not allow one to identify transient perceptual changes that may be linked to the central plasticity observed in juvenile animals. Here, we determined whether a brief period of bilateral auditory deprivation affects sound perception in developing and adult gerbils. Animals were reared with bilateral earplugs, either from postnatal day 11 (P11) to postnatal day 23 (P23) (a manipulation previously found to disrupt gerbil cortical properties), or from P23-P35. Fifteen days after earplug removal and restoration of normal thresholds, animals were tested on their ability to detect the presence of amplitude modulation (AM), a temporal cue that supports vocal communication. Animals reared with earplugs from P11-P23 displayed elevated AM detection thresholds, compared with age-matched controls. In contrast, an identical period of earplug rearing at a later age (P23-P35) did not impair auditory perception. Although the AM thresholds of earplug-reared juveniles improved during a week of repeated testing, a subset of juveniles continued to display a perceptual deficit. Furthermore, although the perceptual deficits induced by transient earplug rearing had resolved for most animals by adulthood, a subset of adults displayed impaired performance. Control experiments indicated that earplugging did not disrupt the integrity of the auditory periphery. Together, our results suggest that P11-P23 encompasses a critical period during which sensory deprivation disrupts central mechanisms that support auditory perceptual skills. SIGNIFICANCE STATEMENT Sensory systems are particularly malleable during development. This heightened degree of plasticity is beneficial because it enables the acquisition of complex skills, such as music or language. However, this plasticity comes with a cost: nervous system development displays an increased vulnerability to the sensory environment. Here, we identify a precise developmental window during which mild hearing loss affects the maturation of an auditory perceptual cue that is known to support animal communication, including human speech. Furthermore, animals reared with transient hearing loss display deficits in perceptual learning. Our results suggest that speech and language delays associated with transient or permanent childhood hearing loss may be accounted for, in part, by deficits in central auditory processing mechanisms.

Lipid-rich matrices are often sinks for lipophilic contaminants, such as pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). Typically methods for contaminant extraction and cleanup for lipid-rich matrices require multiple cleanup steps; however, a selective pressurized liquid extraction (SPLE) technique requiring no additional cleanup has been developed for the simultaneous extraction and cleanup of whale earwax (cerumen; a lipid-rich matrix). Whale earwax accumulates in select whale species over their lifetime to form wax earplugs. Typically used as an aging technique in cetaceans, layers or laminae that comprise the earplug are thought to be associated with annual or semiannual migration and feeding patterns. Whale earplugs (earwax) represent a unique matrix capable of recording and archiving whales' lifetime contaminant profiles. This study reports the first analytical method developed for identifying and quantifying lipophilic persistent organic pollutants (POPs) in a whale earplug including organochlorine pesticides, polychlorinated biphenyls (PCBs), and polybrominated diphenyl ethers (PBDEs). The analytical method was developed using SPLE to extract contaminants from ∼0.25 to 0.5g aliquots of each lamina of sectioned earplug. The SPLE was optimized for cleanup adsorbents (basic alumina, silica gel, and Florisil(®)), adsorbent to sample ratio, and adsorbent order. In the optimized SPLE method, the earwax homogenate was placed within the extraction cell on top of basic alumina (5g), silica gel (15g), and Florisil(®) (10g) and the target analytes were extracted from the homogenate using 1:1 (v/v) dichloromethane:hexane. POPs were analyzed using gas chromatography-mass spectrometry with electron capture negative ionization and electron impact ionization. The average percent recoveries for the POPs were 91% (±6% relative standard deviation), while limits of detection and quantification ranged from 0.00057 to 0.96ngg(-1) and 0.0017 to 2.9ngg(-1), respectively. Pesticides, PCBs, and PBDEs, were measured in a single blue whale (Balaenoptera musculus) cerumen lamina at concentrations ranging from 0.11 to 150ng g(-1). Copyright © 2013 Elsevier B.V.

Study of the occlusion effect induced by an earplug: Numerical modelling and experimental validation
NASA Astrophysics Data System (ADS)
Brummund, Martin
Despite existing limits for occupational noise exposure, professional hearing loss remains a high priority problem both in Quebec and worldwide. Several approaches exist to protect workers from harmful noise levels. The most frequently employed short term solution includes the distribution of hearing protection devices (HPD) such as earplugs and ear muffs. While HPDs offer an inexpensive (e.g. direct cost) and efficient means of protection workers often only tend to wear HPDs for limited amounts of time and, thus, remain at risk of developing professional hearing loss. Discomfort while using HPDs contributes to HPD underutilization and non-use. Two more general categories of discomfort can be distinguished. The category physical discomfort includes, for instance, problems such as heating of the ear and irritation of the ear canal that that occur upon earplug insertion. The category auditory discomfort refers to alterations in the auditory perception of sounds and one's own voice as well as hindered workplace communications. One important auditory discomfort that promotes HPD non-use is the occlusion effect. The occlusion effect occurs upon earplug insertion and describes sound amplification phenomena in the occluded ear canal at the low frequencies. The sound amplification is both perceivable and measurable (e.g., open and occluded sound pressure levels, hearing threshold shift). Additionally, the occlusion effect causes the HPD wearer to perceive his/her own voice as being distorted (e.g. hollow sounding) and physiological noises (e.g. respiration, blood circulation) are amplified also subsequent to earplug insertion. Reducing the occlusion effect has the potential to increase the auditory comfort of HPDs and could help preventing occupational hearing loss in the future. In order to improve this and other shortcomings observed with currently existing HPDs a large research collaboration between the Robert-Sauve research institute in occupational health and safety (IRSST) and the Ecole de technologie superieure (ETS) has been launched. The present study represents a part of this collaboration and aims at studying the occlusion effect of the system earplug - ear canal through the development of novel numerical models and experimental methods.

Provision of nutrition support therapies in the recent Iraq and Afghanistan conflicts.
Stankorb, Susan M; Ramsey, Casside; Clark, Heidi; Osgood, Tamara
2014-10-01
This article describes the experience of nutrition support practitioners, specifically dietitians, providing care to combat casualties. It provides a brief overview of dietitians' induction into armed service but focuses primarily on their role in providing nutrition support during the most recent conflicts in Iraq and Afghanistan. The current system of combat casualty care is discussed with specific emphasis on providing early and adequate nutrition support to U.S. combat casualties from injury, care in theater combat support hospitals (CSHs)/expeditionary medical support (EMEDs), and en route care during critical care air transport (CCAT) up to arrival at treatment facilities in the United States. The article also examines practices and challenges faced in the CSHs/EMEDs providing nutrition support to non-U.S. or coalition patients. Over the past decade in armed conflicts, dietitians, physicians, nurses, and other medical professionals have risen to challenges, have implemented systems, and continue working to optimize treatment across the spectrum of combat casualty care.

Evaluation and treatment of severe hyperacusis.
Valente, M; Goebel, J; Duddy, D; Sinks, B; Peterein, J
2000-06-01
A 52-year-old male was evaluated by the authors after initially reporting fullness in his left ear while traveling on an airplane. A unique feature of the patient's complaint was the development of severe bilateral hyperacusis (loudness discomfort levels of between 20-34 dB HL) in spite of the fact that the hearing loss was initially reported in the left ear. To achieve loudness comfort, the patient was initially fit with ER-25 musician earplugs that proved to be unsuccessful. The patient next purchased earplugs and earmuffs from a gun shop in order to obtain relief from the pain and discomfort caused by his exposure to everyday environmental sounds. This paper describes the use of hearing devices that proved to be effective in providing attenuation sufficient that the patient rarely needs to rely on earplugs and earmuffs for relief from his hyperacusis.

This study explored attitudes toward leisure noise, use of hearing protection, and perceived susceptibility to leisure-noise damage in young adults with hearing problems. Twelve participants aged between 18 and 35 years took part in a semistructured interview. Data were analyzed using framework analysis. The results showed that a positive attitude to noise, a passion for loud music, a lack of knowledge of the consequences of noise damage, and perceived low risk of hearing problems were associated with people not using earplugs. The aesthetics, comfort, perceived effects on music quality and attitude of others were all barriers to earplug use. Of those who had used earplugs, previous hearing-related symptoms and concern about future hearing damage were the main motivators for use. Four types of people were identified to describe the variation in attitudes and behaviors: those who had no change in behavior or concern about damage; those who were concerned and used earplugs; those who were concerned and avoided loud venues; and those who were concerned about communication difficulties only. Considering the wide variability, it may be more effective to shift attention from trying to change individual attitudes and behaviors to considering systemic changes to protect hearing, through ensuring the music industry and relevant authorities take greater responsibility.
Leadership, cohesion, morale, and the mental health of UK Armed Forces in Afghanistan.

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.

Olivocochlear Efferent Control in Sound Localization and Experience-Dependent Learning
Irving, Samuel; Moore, David R.; Liberman, M. Charles; Sumner, Christian J.
2012-01-01
Efferent auditory pathways have been implicated in sound localization and its plasticity. We examined the role of the olivocochlear system (OC) in horizontal sound localization by the ferret and in localization learning following unilateral earplugging. Under anesthesia, adult ferrets underwent olivocochlear bundle section at the floor of the fourth ventricle, either at the midline or laterally (left). Lesioned and control animals were trained to localize 1 s and 40ms amplitude-roved broadband noise stimuli from one of 12 loudspeakers. Neither type of lesion affected normal localization accuracy. All ferrets then received a left earplug and were tested and trained over 10 d. The plug profoundly disrupted localization. Ferrets in the control and lateral lesion groups improved significantly during subsequent training on the 1 s stimulus. No improvement (learning) occurred in the midline lesion group. Markedly poorer performance and failure to learn was observed with the 40 ms stimulus in all groups. Plug removal resulted in a rapid resumption of normal localization in all animals. Insertion of a subsequent plug in the right ear produced similar results to left earplugging. Learning in the lateral lesion group was independent of the side of the lesion relative to the earplug. Lesions in all reported cases were verified histologically. The results suggest the OC system is not needed for accurate localization, but that it is involved in relearning localization during unilateral conductive hearing loss. PMID:21325517

The aim of this study was to determine the impact of combat sports practice on bone mineral density (BMD) and to analyze the relationship between bone parameters and anthropometric measurements, bone markers, and activity index (AI). In other words, to detect the most important determinant of BMD in the adolescent period among combat sports athletes. Fifty athletes engaged in combat sports, mean age 17.1±0.2 yr, were compared with 30 sedentary subjects who were matched for age, height, and pubertal stage. For all subjects, the whole-body BMD, lumbar spine BMD (L2-L4), and BMD in the pelvis, arms, and legs was measured by dual-energy X-ray absorptiometry, and anthropometric measurements were evaluated. Daily calcium intake, bone resorption, and formation markers were measured. BMD measurements were greater in the combat sports athletes than in the sedentary group (p<0.01). Weight, body mass index, and lean body mass were significantly correlated with BMD in different sites. Daily calcium consumption lower than daily calcium intake recommended in both athletes and sedentary group. AI was strongly correlated with all BMD measurements particularly with the whole body, legs, and arms. Negative correlations were observed between bone markers and BMD in different sites. The common major predictor of BMD measurements was AI (p<0.0001). AI associated to lean body mass determined whole-body BMD until 74%. AI explained both BMD in arms and L2-L4 at 25%. AI associated to height can account for 63% of the variance in BMD legs. These observations suggested that the best model predicting BMD in different sites among adolescent combat sports athletes was the AI. Children and adolescents should be encouraged to participate in combat sports to maximize their bone accrual. Copyright © 2015 The International Society for Clinical Densitometry.

Better protection from blasts without sacrificing situational awareness.
Killion, Mead C; Monroe, Tim; Drambarean, Viorel
2011-03-01
A large number of soldiers returning from war report hearing loss and/or tinnitus. Many deployed soldiers decline to wear their hearing protection devices (HPDs) because they feel that earplugs interfere with their ability to detect and localize the enemy and their friends. The detection problem is easily handled in electronic devices with low-noise microphones. The localization problem is not as easy. In this paper, the factors that reduce situational awareness--hearing loss and restricted bandwidth in HPD devices--are discussed in light of available data, followed by a review of the cues to localization. Two electronic blast plug earplugs with 16-kHz bandwidth are described. Both provide subjectively transparent sound with regard to sound quality and localization, i.e., they sound almost as if nothing is in the ears, while protecting the ears from blasts. Finally, two formal experiments are described which investigated localization performance compared to popular existing military HPDs and the open ear. The tested earplugs performed well regarding maintaining situational awareness. Detection-distance and acceptance studies are underway.

Whale earplugs, historically used for aging, were used to reconstruct lifetime stable isotope profiles for carbon (δ13C) and nitrogen (δ15N) for individual whales by delaminating lamina within the earplug. These stable isotope profile, which provide Continuous lifetime records of feeding, foraging ecology, and migration, were determined for 20 individuals from 4 baleen species including fin, minke, humpback, and blue whales spanning more than a century (1869 - 2014) using stable isotope analysis. Approximately 1 mg tissue from each lamina (n=1200) was analyzed for carbon and nitrogen stable isotope using continuous flow isotope ratio mass spectrometer (CF-IRMS). This research using whale earplugs have combined age estimates with stable isotope measurements to reconstruct lifetime foraging profiles with a 6-month resolution, providing an unprecedented opportunity to assess periods and trends in dietary fluctuations as well as migration between different foraging area which have distinct isotope values. Trends with these profiles suggest long-term changing in migration, while annual variability highlights seasonal fasting and feeding. Isotopic ratios were also used to identify subpopulations of Atlantic fin whales, which enabled us to assign unidentified humpback and minke whales to the Atlantic or Pacific Oceans. This historical archive of data provides us an unprecedented tool to assess long term marine ecosystem and subsequently marine organism transition to alternate foraging area and shed light on the whale's population status in the Northern hemisphere.

Preparing for Combat Readiness for the Fight: Physical Performance Profile of Female U.S. Marines.
Kelly, Karen R; Jameson, Jason T
2016-03-01
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.
Advanced protection technology for ground combat vehicles.
Bosse, Timothy G
2012-01-01
Just as highway drivers use radar detectors to attempt to stay ahead of police armed with the latest radar technology, the Armed Forces are locked in a spiral to protect combat vehicles and their crews against the latest threats in both the contemporary operating environment and the anticipated operating environment (ie, beyond 2020). In response to bigger, heavier, or better-protected vehicles, adversaries build and deploy larger explosive devices or bombs. However, making improvements to combat vehicles is much more expensive than deploying larger explosives. In addition, demand is increasing for lighter-weight vehicles capable of rapid deployment. Together, these two facts give the threat a clear advantage in the future. To protect vehicles and crews, technologies focusing on detection and hit avoidance, denial of penetration, and crew survivability must be combined synergistically to provide the best chance of survival on the modern battlefield.

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.

Foulis, SA, Redmond, JE, Frykman, PN, Warr, BJ, Zambraski, EJ, and Sharp, MA. U.S. Army physical demands study: reliability of simulations of physically demanding tasks performed by combat arms soldiers. J Strength Cond Res 31(12): 3245-3252, 2017-Recently, the U.S. Army has mandated that soldiers must successfully complete the physically demanding tasks of their job to graduate from their Initial Military Training. Evaluating individual soldiers in the field is difficult; however, simulations of these tasks may aid in the assessment of soldiers' abilities. The purpose of this study was to determine the reliability of simulated physical soldiering tasks relevant to combat arms soldiers. Three cohorts of ∼50 soldiers repeated a subset of 8 simulated tasks 4 times over 2 weeks. Simulations included: sandbag carry, casualty drag, and casualty evacuation from a vehicle turret, move under direct fire, stow ammunition on a tank, load the main gun of a tank, transferring ammunition with a field artillery supply vehicle, and a 4-mile foot march. Reliability was assessed using intraclass correlation coefficients (ICCs), standard errors of measurement (SEMs), and 95% limits of agreement. Performance of the casualty drag and foot march did not improve across trials (p > 0.05), whereas improvements, suggestive of learning effects, were observed on the remaining 6 tasks (p ≤ 0.05). The ICCs ranged from 0.76 to 0.96, and the SEMs ranged from 3 to 16% of the mean. These 8 simulated tasks show high reliability. Given proper practice, they are suitable for evaluating the ability of Combat Arms Soldiers to complete the physical requirements of their jobs.

It has been postulated that the violent behavior that characterizes armed conflict is reinforced by the possibility of receiving rewards. The present study examined the potential influence of two types of rewards in an ongoing setting of conflict: extrinsic and intrinsic rewards. Former combatants active in the Democratic Republic of the Congo (N = 198) were interviewed and questioned about the way they were recruited, the offenses they committed during combat, their level of perceived intrinsic rewards (i.e., appetitive perception of violence), and the number of received extrinsic rewards during their time in the armed group (e.g., money, extra food, alcohol, or drugs). A moderated multiple regression analysis showed that the number of received extrinsic rewards and the level of intrinsic rewards were significantly positively related to the number of different types of offenses committed. In contrast to our expectations and previous findings, the recruitment type (forced conscription vs. voluntary enlistment) did not moderate this relation. Our findings suggest that both types of rewards play a role in committing violence during combat. We suggest, therefore, that reintegration programs should not only consider the influence of extrinsic rewards, but also need to address the influence of intrinsic rewards to counter violent behavior among former combatants.

Experiences and perceptions of sexual harassment in the Canadian forces combat arms.
Gill, Ritu; Febbraro, Angela R
2013-02-01
Recent studies examining sexual harassment in the military indicate a decrease in reports of harassment, which may be attributed to several factors, including zero-tolerance policies or anti-harassment programs. However, the decrease may also be attributed to fears of losing one's job or of being derogated by colleagues if harassment is reported. This qualitative study of women employed in the Canadian combat arms examined spontaneously shared perceptions and experiences of sexual harassment. Six of the 26 women interviewed shared their experiences or perceptions of harassment, including concerns about potential repercussions of reporting. Implications for gender integration in military organizations are discussed.

[Polymeric hearing protectors in sport shooting].

Using hearing protectors during exposition to noise is fundamental to hearing loss prevention. The optimal choice of hearing protectors should take into consideration not only the physical characteristics of the acoustic environment which imply the traumatic action of noise, but also some individual preferences of the user. All contemporary produced hearing protectors both earmuffs as well as earplugs are made of synthetic polymers e.g. ABS, polyvinylchloride, polyethylene, polyurethathane, silicone rubbers. The type of the material used determines hardness, incompressibility and plasticity of the hear protector and may cause some discomfort. A special group of individuals exposed to noise are sport shooters in which (whose) case the exposition to impact noise is several times higher above standards. The aim of this work was an appraisal of the individual preferences in the choice of hearing protectors. The properties of polymers used for the production of hearing protectors were also taken into consideration. 104 females and 93 males representing master class were interviewed in this study. The analysis of the answers indicated that abandoning of hearing protectors by some shooters is due to the frequent skin irritations, overheating in the ear canal and allergy. Shooters linked these problems with the materials used for the production of hearing protectors. Earplugs were preferred by females, whereas males indicated earmuffs as their preferred choice. Females preferred earplugs made of soft materials which can be easily fitted to ear canal. Those males who used earplugs preferred protectors made of hard plastics as they thought this make better insulation. It can be concluded that the choice of the hearing protectors should not be done on the basis acoustic signal characteristics only, but also should reduce some discomforts resulting from properties of the materials used for their production.

Noise exposures and hearing loss in the mining industry continue to be a major problem, despite advances in noise control technologies. This study evaluated the effectiveness of engineering, administrative, and personal noise controls using both traditional and in-ear dosimetry by job task, work shift, and five types of earplug. The noise exposures of 22 miners performing deep shaft-sinking tasks were evaluated during 56 rotating shifts in an underground mine. Miners were earplug-insertion trained, earplug fit-tested, and monitored utilizing traditional and in-ear dosimetry. The mean TWA8 noise exposure via traditional dosimetry was 90.1 ± 8.2 dBA, while the mean in-ear TWA8 was 79.6 ± 13.8 dBA. The latter was significantly lower (p < 0.05) than the Mine Safety and Health Administration (MSHA) personal exposure limit (PEL) of 90 dBA. Dosimetry mean TWA8 noise exposures for bench blowing (103.5 ± 0.9 dBA), jumbo drill operation (103.0 ± 0.8 dBA), and mucking tasks (99.6 ± 4.7 dBA) were significantly higher (p < 0.05) than other tasks. For bench blowing, cable pulling, grinding, and jumbo drill operation tasks, the mean in-ear TWA8 was greater than 85 dBA. Those working swing shift had a significantly higher (p < 0.001) mean TWA8 noise exposure (95.4 ± 7.3 dBA) than those working day shift. For percent difference between traditional vs. in-ear dosimetry, there was no significant difference among types of earplug used. Reflective of occupational hearing loss rate trends across the mining industry, this study found that, despite existing engineering and administrative controls, noise exposure levels exceeded regulatory limits, while the addition of personal hearing protection limited excessive exposures.

To apply theory of reasoned action at survey on welding workers occupational health protection behaviors and explore related influencing factors. nine companies were randomly selected from areas with many welding works in Zhejiang Province. All welding workers were surveyed using a questionnaire based on theory of reasoned action. 10.06%, 26.80% and 37.50% of the respondents never or seldom used eyeshade, mask and earplug, respectively. After controlling the socio-demographic factors, welding workers' behavioral belief was correlated with the behaviors of eyeshade-mask and earplug use (χ(2) = 31.88, 18.77 and 37.77, P < 0.01). the subjective norm of company was correlated with all protection behaviors (χ(2) = 20.60, 10.98 and 19.86, P < 0.01), the subjective norm of colleague was correlated with mask and earplug use, (χ(2) = 27.43, 36.39, P < 0.01), and the subjective norm of family was correlated with mask use (χ(2) = 5.73, P < 0.05). Theory of reasoned action is suitable for welding worker occupational health related behaviors. It is useful to improve occupational health education, to effectively select health education objective and to tailor health education contents.

Sleep deprivation is common in critically ill patients in the intensive care unit (ICU). Noise and light in the ICU and the reduction in plasma melatonin play the essential roles. The aim of this study was to determine the effect of simulated ICU noise and light on nocturnal sleep quality, and compare the effectiveness of melatonin and earplugs and eye masks on sleep quality in these conditions in healthy subjects. This study was conducted in two parts. In part one, 40 healthy subjects slept under baseline night and simulated ICU noise and light (NL) by a cross-over design. In part two, 40 subjects were randomly assigned to four groups: NL, NL plus placebo (NLP), NL plus use of earplugs and eye masks (NLEE) and NL plus melatonin (NLM). 1 mg of oral melatonin or placebo was administered at 21:00 on four consecutive days in NLM and NLP. Earplugs and eye masks were made available in NLEE. The objective sleep quality was measured by polysomnography. Serum was analyzed for melatonin levels. Subjects rated their perceived sleep quality and anxiety levels. Subjects had shorter total sleep time (TST) and rapid eye movement (REM) sleep, longer sleep onset latency, more light sleep and awakening, poorer subjective sleep quality, higher anxiety level and lower serum melatonin level in NL night (P <0.05). NLEE had less awakenings and shorter sleep onset latency (P <0.05). NLM had longer TST and REM and shorter sleep onset latency (P <0.05). Compared with NLEE, NLM had fewer awakenings (P = 0.004). Both NLM and NLEE improved perceived sleep quality and anxiety level (P = 0.000), and NLM showed better than NLEE in perceived sleep quality (P = 0.01). Compared to baseline night, the serum melatonin levels were lower in NL night at every time point, and the average maximal serum melatonin concentration in NLM group was significantly greater than other groups (P <0.001). Compared with earplugs and eye masks, melatonin improves sleep quality and serum melatonin levels better in healthy subjects exposed to simulated ICU noise and light.

UNEQUAL RISK: COMBAT OCCUPATIONS IN THE VOLUNTEER MILITARY
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

Bleeding from extremity wounds is the number one cause of preventable death on the battlefield and current research stresses the importance of training in preparing every Soldier to use tourniquets. HapMed is designed to provide tourniquet application training to combat medics and Soldiers using a blended training solution encompassing information, demonstration, practice, and feedback. The system combines an instrumented manikin arm, PDA, and computer. The manikin arm provides several training options including stand-alone, hands-on skills training in which soldiers can experience the actual torque required to staunch bleeding from an extremity wound and be timed on tourniquet application. This is more realistic than using a block of wood to act as a limb, which is often how training is conducted today. Combining the manikin arm with the PDA allows instructors to provide scenario based training. In a classroom or field setting, an instructor can specify wound variables such as location, casualty size, and whether the wound is a tough bleed. The PDA also allows more detailed feedback to be provided. Finally, combining the manikin arm with game-based technologies, the third component, provides opportunities to build knowledge and to practice battlefield decision making. Not only do soldiers learn how to apply a tourniquet, but when to apply a tourniquet in combat. The purpose of the paper is to describe the learning science underlying the design of HapMed, illustrate the training system and ways it is being expanded to encompass other critical life-saving tasks, and report on feedback received from instructors and trainees at military training and simulation centers.

The concept of the military wound is not an easy entity to define as the wounds seen in conflict can be of many types: those caused by recognized or improvised weapon systems may have similarities to civilian wounds as well as the wounds soldiers sustain outside of battle. This article will focus on the current treatment approaches to combat wounds sustained by the deployed UK Armed Forces personnel. PMID:27785380

Spectral analysis of hearing protector impulsive insertion loss.
Fackler, Cameron J; Berger, Elliott H; Murphy, William J; Stergar, Michael E
2017-01-01
To characterise the performance of hearing protection devices (HPDs) in impulsive-noise conditions and to compare various protection metrics between impulsive and steady-state noise sources with different characteristics. HPDs were measured per the impulsive test methods of ANSI/ASA S12.42- 2010 . Protectors were measured with impulses generated by both an acoustic shock tube and an AR-15 rifle. The measured data were analysed for impulse peak insertion loss (IPIL) and impulsive spectral insertion loss (ISIL). These impulsive measurements were compared to insertion loss measured with steady-state noise and with real-ear attenuation at threshold (REAT). Tested HPDs included a foam earplug, a level-dependent earplug and an electronic sound-restoration earmuff. IPIL for a given protector varied between measurements with the two impulse noise sources, but ISIL agreed between the two sources. The level-dependent earplug demonstrated level-dependent effects both in IPIL and ISIL. Steady-state insertion loss and REAT measurements tended to provide a conservative estimate of the impulsively-measured attenuation. Measurements of IPIL depend strongly on the source used to measure them, especially for HPDs with less attenuation at low frequencies. ISIL provides an alternative measurement of impulse protection and appears to be a more complete description of an HPD's performance.

Laboratory levels of perceived noise attenuation as heard using earplugs are always higher than the real levels that can be achieved at the workplace. The employer is bound by law to supply individual hearing protection devices (HPDs), to assess their efficiency and efficacy, and also to inform and train workers on the correct use of HPDs. This study assessed the real "personal attenuation rating" (PAR) of HPDs used by workers at the workplace, before (PAR A) and after (PAR B) specific and individual training. These values were also compared with the theoretical "single number rating" (SNR) provided by the manufacturer. The study covered all the 65 male employees of an awnings factory, using the E-A-RfitTM computerized method, which can measure PARs, based on the difference between sound pressures recorded by an "outside" microphone and an "inside" microphone placed in the auditory canal, with earplugs inserted, before (PAR A) and after (PAR B), i.e., the specific and individual training described above. PARs B were always definitely higher than PARs A, both for all tested frequencies and the corresponding average values, which were automatically detected by E-A-RfitTM. Furthermore the same PARs B were decidedly lower than the respective SNRs supplied by the manufacturer on the basis of laboratory assessments. These data prove that specific and individual training for workers improves the performance of earplugs, contributing to a more appropriate secondary prevention of the effects of noise on hearing; they also prove that the real attenuation recorded in workers are always lower than those supplied by the manufacturer of the devices. It is recommended that the E-A-RfitTM system, which allowed these results to be achieved objectively, should be normally used to assess exposure to noise in workers, when HPDs are worn.

The study compared the effect of earplug-delivered sleep-inducing music on sleep in persons with percutaneous transluminal coronary angiography in the cardiac care unit. Diverse types of music have been claimed to improve sleeping elsewhere, but relatively little is known in South Korea. Most studies investigating the effect of sleep-inducing music on sleep have involved persons with insomnia, even though many persons with cardiovascular disease in the intensive care unit suffer from sleeping problems. There is a need to investigate the effect of sleep-inducing music on sleep disorders in persons with percutaneous transluminal coronary angiography in the cardiac care unit. An experimental research design was used. Data collection was conducted in the cardiac care unit of K University Hospital in D city, from 3 September-4 October 2010. Fifty-eight subjects participated and were randomly assigned to the experimental group (earplug-delivered sleep-inducing music for 52 min beginning at 10:00 pm, while wearing an eyeshield, n = 29) and the control group (no music, but earplugs and eyeshield worn, n = 29). The quantity and quality of sleep were measured using questionnaires at 7 am the next morning for each group. Participants in the experimental group reported that the sleeping quantity and quality were significantly higher than control group (t = 3·181, p = 0·002, t = 5·269, p < 0·001, respectively). Sleep-inducing music significantly improved sleep in patients with percutaneous transluminal coronary angiography at a cardiac care unit. Offering earplugs and playing sleep-inducing music may be a meaningful and easily enacted nursing intervention to improve sleep for intensive care unit patients. Nurses working at cardiac care unit can use music to improve sleeping in clients with percutaneous transluminal coronary angiography. © 2011 Blackwell Publishing Ltd.

Combat deployments are characterized by high operational demands with limited opportunities for sleep leading to fatigue and degraded cognitive and operational performance. Caffeine in moderate doses is recognized as an effective intervention for physical and cognitive decrements associated with sleep loss. This report is based on data collected by two separate, independently conducted surveys administered in Afghanistan in 2011-2012. It assessed caffeine use and sleep disruption among U.S. Army combat soldiers (J-MHAT 8; n = 518) and among deployed soldiers with different military assignments (USARIEM Deployment Survey; n = 260). Daily caffeine intake assessed in the J-MHAT 8 survey averaged 404 ± 18 mg. In the USARIEM Deployment Survey, intake was 303 ± 29 mg and was significantly higher among combat arms soldiers (483 ± 100 mg) compared to combat service support personnel (235 ± 23 mg). In both surveys, over 55% of total caffeine intake was from energy drinks. Additional sources of caffeine included coffee, tea, sodas, gum, candy, and over-the-counter medications. Higher caffeine intake was not associated with ability to fall asleep at night or wake-up in the morning (J-MHAT 8 survey). Higher caffeine consumption was associated with disrupted sleep from high operational tempo and nighttime duties of combat operations. Overall caffeine consumption and energy drink use in Afghanistan was greater than among non-deployed soldiers and civilians. Caffeine was frequently used as a countermeasure during night operations to offset adverse effects of sleep loss on physical and cognitive function, consistent with current Department of the Army recommendations.

The aim of this study was firstly to investigate the correlation between bone parameters and grip strength (GS) in hands, explosive legs power (ELP), and hormonal parameters; second, to identify the most determinant variables of bone mineral density (BMD) among adolescent combat sport athletes. Fifty combat sport athletes aged 17.1 ± 0.2 year were compared with 30 sedentary subjects matched for age, height, and pubertal stage. For all subjects, the BMD in deferent sites associated with anthropometric parameters were measured by dual-energy X-ray absorptiometry. The growth hormone (GH) and testosterone (TESTO) concentrations were tested. The GS in dominant (GSDA) and nondominant arms (GSNDA) and ELP were evaluated. All BMD measured were greater in athletes than in sedentary group (p<0.01). The GS and ELP showed higher values in athletes than in sedentary group (p<0.01). The BMD in all sites were correlated with weight, but without correlation with height. The GSNDA and ELP were significantly correlated with BMD of both spine and legs. The GH was correlated with the BMD of whole body and spine (p<0.05). The TESTO was only correlated with BMD of the arms (p<0.01). The best predictor of BMD measurements is GSNDA. This study has proved the osteogenic effect of combat sports practice, especially judo and karate kyokushinkai. Therefore, children and adolescent should be encouraged to participate in combat sport. Moreover, it suggested that the best model predicting BMD in different sites among adolescent combat sports athletes was the GSNDA.

In previous studies an association between deployment to Iraq or Afghanistan and an overall increased risk for post-traumatic stress disorder (PTSD) in UK armed forces has not been found. The lack of a deployment effect might be explained by including, in the comparison group, personnel deployed on other operations or who have experienced traumatic stressors unrelated to deployment. The sample comprised 8261 regular UK armed forces personnel who deployed to Iraq, Afghanistan or other operational areas or were not deployed. Participants completed the PTSD CheckList-Civilian Version (PCL-C) and provided information about deployment history, demographic and service factors, serious accidents and childhood experiences. Deployment to Iraq or Afghanistan [odds ratio (OR) 1.2, 95% confidence interval (CI) 0.6-2.2] or elsewhere (OR 1.1, 95% CI 0.6-2.0) was unrelated to PTSD although holding a combat role was associated with PTSD if deployed to Iraq or Afghanistan (OR 2.7, 95% CI 1.9-3.9). Childhood adversity (OR 3.3, 95% CI 2.1-5.0), having left service (OR 2.7, 95% CI 1.9-4.0) and serious accident (OR 2.1, 95% CI 1.4-3.0) were associated with PTSD whereas higher rank was protective (OR 0.3, 95% CI 0.12-0.76). For the majority of UK armed forces personnel, deployment whether to Iraq, Afghanistan or elsewhere confers no greater risk for PTSD than service in the armed forces per se but holding a combat role in those deployed to Iraq or Afghanistan is associated with PTSD. Vulnerability factors such as lower rank, childhood adversity and leaving service, and having had a serious accident, may be at least as important as holding a combat role in predicting PTSD in UK armed forces personnel.

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.

Ray, Laura R; Solbeck, Jason A; Streeter, Alexander D; Collier, Robert D
2006-10-01
A hybrid active noise reduction (ANR) architecture is presented and validated for a circumaural earcup and a communication earplug. The hybrid system combines source-independent feedback ANR with a Lyapunov-tuned leaky LMS filter (LyLMS) improving gain stability margins over feedforward ANR alone. In flat plate testing, the earcup demonstrates an overall C-weighted total noise reduction of 40 dB and 30-32 dB, respectively, for 50-800 Hz sum-of-tones noise and for aircraft or helicopter cockpit noise, improving low frequency (<100 Hz) performance by up to 15 dB over either control component acting individually. For the earplug, a filtered-X implementation of the LyLMS accommodates its nonconstant cancellation path gain. A fast time-domain identification method provides a high-fidelity, computationally efficient, infinite impulse response cancellation path model, which is used for both the filtered-X implementation and communication feedthrough. Insertion loss measurements made with a manikin show overall C-weighted total noise reduction provided by the ANR earplug of 46-48 dB for sum-of-tones 80-2000 Hz and 40-41 dB from 63 to 3000 Hz for UH-60 helicopter noise, with negligible degradation in attenuation during speech communication. For both hearing protectors, a stability metric improves by a factor of 2 to several orders of magnitude through hybrid ANR.

Multimedia shooting training systems are increasingly being used in the training of security staff and uniformed services. An advanced practicing-training system SPARTAN for simulation of small arms shooting has been designed and manufactured by Autocomp Management Ltd. and Military Institute of Armament Technology for the Polish Ministry of National Defence. SPARTAN is a stationary device designed to teach, monitor and evaluate the targeting of small arms and to prepare soldiers for: • firing the live ammunition at open ranges for combat targets and silhouettes • detection, classification and engagement of real targets upon different terrains, weather conditions and periods during the day • team work as a squad during the mission by using different types of arms • suitable reactions in untypical scenarios. Placed in any room the training set consists of: • the projection system that generates realistic 3D imaging of the battlefield (such as combat shooting range) in high-resolution • system that tracks weapons aiming points • sound system which delivers realistic mapping of acoustic surroundings • operator station with which the training is conducted and controlled • central processing unit based on PC computers equipped with specialist software realizing individual system functions • units of smart weapons equipped with radio communication modules, injection laser diodes and pneumatic reloading system. The system make possible training by firing in dynamic scenarios, using combat weapons and live ammunition against visible targets moving on a screen. The use of infrared camera for detecting the position of impact of a projectile.

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.

Infection is a major complication associated with combat-related injuries. Beside immobilization, wound irrigation, surgical debridement and delayed coverage, post-injury antimicrobials contribute to reduce combat-related infections, particularly those caused by bacteria of the early contamination flora. In modern warfare, bacteria involved in combat-related infections are mainly Gram-negative bacteria belonging to the late contamination flora. These bacteria are frequently resistant or multiresistant to antibiotics and spread through the deployed chain of care. This article exposes the principles of war wounds antimicrobial prophylaxis recommended in the French Armed Forces and highlights the need for high compliance to hygiene standard precautions, adapted contact precautions and judicious use of antibiotics in French deployed military medical treatment facilities (MTF).

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.
Inter-laboratory Comparison of Three Earplug Fit-test Systems
Byrne, David C.; Murphy, William J.; Krieg, Edward F.; Ghent, Robert M.; Michael, Kevin L.; Stefanson, Earl W.; Ahroon, William A.
2017-01-01
The National Institute for Occupational Safety and Health (NIOSH) sponsored tests of three earplug fit-test systems (NIOSH HPD Well-Fit™, Michael & Associates FitCheck, and Honeywell Safety Products VeriPRO®). Each system was compared to laboratory-based real-ear attenuation at threshold (REAT) measurements in a sound field according to ANSI/ASA S12.6-2008 at the NIOSH, Honeywell Safety Products, and Michael & Associates testing laboratories. An identical study was conducted independently at the U.S. Army Aeromedical Research Laboratory (USAARL), which provided their data for inclusion in this report. The Howard Leight Airsoft premolded earplug was tested with twenty subjects at each of the four participating laboratories. The occluded fit of the earplug was maintained during testing with a soundfield-based laboratory REAT system as well as all three headphone-based fit-test systems. The Michael & Associates lab had highest average A-weighted attenuations and smallest standard deviations. The NIOSH lab had the lowest average attenuations and the largest standard deviations. Differences in octave-band attenuations between each fit-test system and the American National Standards Institute (ANSI) sound field method were calculated (Attenfit-test - AttenANSI). A-weighted attenuations measured with FitCheck and HPD Well-Fit systems demonstrated approximately ±2 dB agreement with the ANSI sound field method, but A-weighted attenuations measured with the VeriPRO system underestimated the ANSI laboratory attenuations. For each of the fit-test systems, the average A-weighted attenuation across the four laboratories was not significantly greater than the average of the ANSI sound field method. Standard deviations for residual attenuation differences were about ±2 dB for FitCheck and HPD Well-Fit compared to ±4 dB for VeriPRO. Individual labs exhibited a range of agreement from less than a dB to as much as 9.4 dB difference with ANSI and REAT estimates. Factors such as the experience of study participants and test administrators, and the fit-test psychometric tasks are suggested as possible contributors to the observed results. PMID:27786602

[Epidemiological health surveillance among the troops during combat operations in armed conflicts].
Mel'nichenko, P I
1997-08-01
With local wars and armed conflicts the sanitary-epidemiological situation for the troops and local population shows a tendency to worsen. The main objects of the military medical service at the period of deployment are the preventive measures against troops infection from local sources by virus hepatitis A, bacterial dysentery, typhoid, cholera etc. As a rule, combat actions result in communal service destruction, low quality of potable water, soil contamination and worsening sanitary norms and standards. Also, there is a danger of reactivation of the natural centres of infection due to large-scale defence earthworks in the region of operations. The experience of the military medical service in Afghanistan and Chechnya proves, that a multimedia approach to preventive antiepidemic measures is necessary together with the emphasis on the most important actions against infections that represent the biggest danger for the land troops.

This study investigated the impact of violent experiences during childhood, posttraumatic stress disorder (PTSD) and appetitive aggression on everyday violent behavior in Burundian females with varying participation in war. Moreover, group differences in trauma-related and aggression variables were expected. Appetitive aggression describes the perception of violence perpetration as fascinating and appealing and is a common phenomenon in former combatants. Semi-structured interviews were conducted with 158 females, either former combatants, supporters of armed forces or civilians during the civil war in Burundi. The PTSD Symptom Scale Interview was used to assess PTSD symptom severity, the Appetitive Aggression Scale to measure appetitive aggression and the Domestic and Community Violence Checklist to assess both childhood maltreatment and recent aggressive behavior. Former combatants had experienced more traumatic events, perpetrated more violence and reported higher levels of appetitive aggression than supporters and civilians. They also suffered more severely from PTSD symptoms than civilians but not than supporters. The groups did not differ regarding childhood maltreatment. Both appetitive aggression and childhood violence predicted ongoing aggressive behavior, whereas the latter outperformed PTSD symptom severity. These findings support current research showing that adverse childhood experiences and a positive attitude toward aggression serve as the basis for aggressive behavior and promote an ongoing cycle of violence in post-conflict regions. Female members of armed groups are in need of demobilization procedures including trauma-related care and interventions addressing appetitive aggression. PMID:26635666
Epidemiology of U.K. Military Burns 2008-2013.
Page, Felicity; Hamnett, Nathan; D'Asta, Federica; Jeffery, Steven
After sustaining burn injuries overseas, U.K. Armed Forces personnel are evacuated to the Royal Centre for Defence Medicine. The objective was to review the etiology of U.K. Military burns managed at the center between 2008 and 2013. Analysis will aid provision planning and assist in the prevention of burn injuries for future tours. The International Burn Injury Database database of all U.K. Armed Forces burn injured patients evacuated to the Queen Elizabeth University Hospital Birmingham between 2008 and 2013 were reviewed retrospectively. Analysis included patient demographics, injury mechanism, burn severity, management, and mortality. There were 65 military personnel with burn injuries requiring repatriation to the United Kingdom. Percentage of 78.5 were sustained in Afghanistan. The mean age was 25 (18-46) years. Percentage of 70.8 were considered noncombat burn injuries. Of the noncombat burns, the mechanism of injury most commonly involved burning waste and misuse of fuels and scalds. The mean TBSA for all patients was 6% (0.05-51%). Areas most commonly affected included arms, legs, and face. The length of hospital stay for combat vs noncombat burn injury patients was 10 vs 7 days. There were no fatalities. In conclusion, substantially fewer military personnel sustained combat burns between 2008 and 2013 than in preceding study period (19 vs 79). The number of accidental noncombat burns remained constant. The decrease in combat burns may reflect a relative decrease in military intensity and effective protective equipment and safety measures. Further education may allow for an additional decrease in preventable burn injuries.

Detailed acoustic engineering models that explore noise propagation mechanisms associated with noise attenuation and transmission paths created when using hearing protectors such as earplugs and headsets in high noise environments. Biomedical finite element (FE) models are developed based on volume Computed Tomography scan data which provides explicit external ear, ear canal, middle ear ossicular bones and cochlea geometry. Results from these studies have enabled a greater understanding of hearing protector to flesh dynamics as well as prioritizing noise propagation mechanisms. Prioritization of noise mechanisms can form an essential framework for exploration of new design principles and methods in both earplug and earcup applications. These models are currently being used in development of a novel hearing protection evaluation system that can provide experimentally correlated psychoacoustic noise attenuation. Moreover, these FE models can be used to simulate the effects of blast related impulse noise on human auditory mechanisms and brain tissue.

Background In the ongoing conflict in the Democratic Republic of the Congo (DRC), combatants are exposed to massive forms of violence and other traumatic stressors. Nevertheless, many combatants do not suffer from trauma-related disorders, although they have experienced numerous traumatizing events. Perceiving aggressive behavior as fascinating and arousing might be a defense against trauma-related disorders in the violent environment of war and conflict. Objective Thus, in this study we investigated the relationship between the exposure to traumatic stressors, appetitive aggression, and posttraumatic stress disorder (PTSD) symptom severity. We hypothesized that cumulative traumatic experiences correlated positively and appetitive aggression negatively with PTSD symptom severity. Method In total, 105 voluntary male combatants from different armed groups in the eastern DRC took part in this study. In a semistructured interview, respondents were questioned about their exposure to traumatic stressors, the extent of appetitive aggression (Appetitive Aggression Scale) and their PTSD symptom severity (PTSD Symptom Scale - Interview). Results A multiple sequential regression analysis showed that traumatic events were positively related to PTSD symptom severity. For participants with low to medium PTSD symptom severity, appetitive aggression correlated negatively with PTSD symptom severity. Conclusions The results of this study provide further support for earlier findings that repeated exposure to traumatic stressors cumulatively heightens the risk of PTSD and revealed that appetitive aggression buffers the risk of developing PTSD symptoms under certain circumstances. Thus, the perception of aggressive behavior as fascinating and arousing seem to help combatants to adapt to violent environments but may also be one reason for recurrent failure of reintegration programs for excombatants.

Alcohol Use after Combat-Acquired Traumatic Brain Injury: What We Know and Don’t Know
ADAMS, RACHEL SAYKO; CORRIGAN, JOHN D.; LARSON, MARY JO
2012-01-01
Military personnel engage in unhealthy alcohol use at rates higher than their same age, civilian peers, resulting in negative consequences for the individual and jeopardized force readiness for the armed services. Among those returning from combat deployment, unhealthy drinking may be exacerbated by acute stress reactions and injury, including traumatic brain injury (TBI). Combat-acquired TBI is common among personnel in the current conflicts. Although research suggests that impairments due to TBI leads to an increased risk for unhealthy drinking and consequences among civilians, there has been little research to examine whether TBI influences drinking behaviors among military personnel. This article examines TBI and drinking in both civilian and military populations and discusses implications for clinical care and policy. PMID:22485074

Infectious disease complications of combat-related injuries.
Murray, Clinton K
2008-07-01
: 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.

Emotional processing (EP) is crucial for the elaboration and implementation of adaptive social strategies. EP is also necessary for the expression of social cognition and behavior (SCB) patterns. It is well-known that war contexts induce socio-emotional atypical functioning, in particular for those who participate in combats. Thus, ex-combatants represent an ideal non-clinical population to explore EP modulation and to evaluate its relation with SCB. The aim of this study was to explore EP and its relation with SCB dimensions such as empathy, theory of mind and social skills in a sample of 50 subjects, of which 30 were ex-combatants from illegally armed groups in Colombia, and 20 controls without combat experience. We adapted an Emotional Recognition Task for faces and words and synchronized it with electroencephalographic recording. Ex-combatants presented with higher assertion skills and showed more pronounced brain responses to faces than Controls. They did not show the bias toward anger observed in control participants whereby the latter group was more likely to misclassify neutral faces as angry. However, ex-combatants showed an atypical word valence processing. That is, words with different emotions yielded no differences in N170 modulations. SCB variables were successfully predicted by neurocognitive variables. Our results suggest that in ex-combatants the links between EP and SCB functions are reorganized. This may reflect neurocognitive modulations associated to chronic exposure to war experiences.

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.

This article describes and analyzes patterns of lethal violence in Darfur, Sudan, during 2008-09, drawing upon a uniquely detailed dataset generated by the United Nations-African Union hybrid operation in Darfur (UNAMID), combined with data generated through aggregation of reports from open-source venues. These data enable detailed analysis of patterns of perpetrator/victim and belligerent groups over time, and show how violence changed over the four years following the height of armed conflict in 2003-05. During the reference period, violent incidents were sporadic and diverse and included: battles between the major combatants; battles among subgroups of combatant coalitions that were ostensibly allied; inter-tribal conflict; incidents of one-sided violence against civilians by different parties; and incidents of banditry. The conflict as a whole defies easy categorization. The exercise illustrates the limits of existing frameworks for categorizing armed violence and underlines the importance of rigorous microlevel data collection and improved models for understanding the dynamics of collective violence. By analogy with the use of the epidemiological data for infectious diseases to help design emergency health interventions, we argue for improved use of data on lethal violence in the design and implementation of peacekeeping, humanitarian and conflict resolution interventions.

In 2006 and 2007, around 0.4 and 0.7% of all German soldiers involved in missions abroad were registered as suffering from PTSD. The frequency of PTSD in the German Armed Forces was assessed from army records. All soldiers admitted to the German Military Hospital in Hamburg, Germany, with PTSD (n = 117) in the years 2006 and 2007 were assessed by using questionnaires and structure interviews. Risk factors associated with PTSD were identified. Of the 117 soldiers with PTSD, 39.3% were in missions abroad, and 18.0% had participated in combat situations. Five (4.3%) were wounded in combat, and 4 of them had a serious irreversible injury. In total, 53.8% of the PTSD cases were related to injuries or physical/sexual abuse, while 46.2% were due to psychological traumatization. Among soldiers with PTSD who were not abroad, sexual or physical abuse were the most common traumas. In 35.9% of the patients, there was evidence for psychiatric disorders existing before the traumatic event. The percentage of women among sufferers from PTSD was significantly higher than the proportion of women in the armed forces (30.8% vs. 5.17%). A careful psychiatric screening before recruitment might help to identify persons at risk of PTSD.

The use of improvised explosive devices (IEDs) has had a profound effect on battlefield trauma in the 21st century. Historically, wounds to the genitourinary (GU) structures have been less common than extremity and penetrating abdominal trauma in combat operations. GU injury incidence, severity, and associated injuries secondary to the use of this weapon in Operations Iraqi and Enduring Freedom has not been described. Data from the Department of Defense Trauma Registry was reviewed for combat-related GU injuries in Operations Iraqi and Enduring Freedom from 2001 to 2011. All wounded US armed service members are included in this database. Subjects were selected by a query of current procedural terminology and DRG International Classification of Diseases-9th Rev. codes related to traumatic injury of the penis, scrotum, testicles, and urethra. A retrospective chart review was performed for each patient to identify the date of injury, the mechanism of injury, and the associated traumatic wounds. Subjects' follow-up records were reviewed until present time or separation from active duty. A total of 501 soldiers sustained lower GU trauma, with a total of 729 injuries. Of these casualties, 448 (89%) were wounded by IEDs. Dismounted injuries (87%) made up more of the cohort than did vehicular. Specific trauma sites include 149 (20%) penile, 260 (36%) testicular, 284 (39%) scrotal, and 36 (5%) urethral injuries. The 180 limb amputations (36%) and 86 fractures (17%) were the most encountered concomitant skeletal wounds among service members with GU injuries. This is the first review of all lower GU trauma sustained by all US armed service members in current overseas combat operations. Combat-related lower GU trauma is primarily caused by IEDs in the spectrum of complex dismounted blast injuries. The mechanism primarily results in multisystem injury, with isolated GU involvement being uncommon. Continued evaluation of long-term sequelae, including sexual, urinary, and reproductive dysfunction, is needed. Epidemiologic study, level V.

Civilian suicide rates vary by occupation in ways related to occupational stress exposure. Comparable military research finds suicide rates elevated in combat arms occupations. However, no research has evaluated variation in this pattern by deployment history, the indicator of occupation stress widely considered responsible for the recent rise in the military suicide rate. The joint associations of Army occupation and deployment history in predicting suicides were analysed in an administrative dataset for the 729 337 male enlisted Regular Army soldiers in the US Army between 2004 and 2009. There were 496 suicides over the study period (22.4/100 000 person-years). Only two occupational categories, both in combat arms, had significantly elevated suicide rates: infantrymen (37.2/100 000 person-years) and combat engineers (38.2/100 000 person-years). However, the suicide rates in these two categories were significantly lower when currently deployed (30.6/100 000 person-years) than never deployed or previously deployed (41.2-39.1/100 000 person-years), whereas the suicide rate of other soldiers was significantly higher when currently deployed and previously deployed (20.2-22.4/100 000 person-years) than never deployed (14.5/100 000 person-years), resulting in the adjusted suicide rate of infantrymen and combat engineers being most elevated when never deployed [odds ratio (OR) 2.9, 95% confidence interval (CI) 2.1-4.1], less so when previously deployed (OR 1.6, 95% CI 1.1-2.1), and not at all when currently deployed (OR 1.2, 95% CI 0.8-1.8). Adjustment for a differential 'healthy warrior effect' cannot explain this variation in the relative suicide rates of never-deployed infantrymen and combat engineers by deployment status. Efforts are needed to elucidate the causal mechanisms underlying this interaction to guide preventive interventions for soldiers at high suicide risk.

Injuries associated with combat sports, active component, U.S. Armed Forces, 2010-2013.
2014-05-01
The practice of combat sports creates a potential for training- and sports-related injuries among military members. During the 4-year surveillance period, there were 12,108 cases of injuries associated with combat sports among active component service members; the overall incidence rate was 21.0 per 10,000 person-years (p-yrs). The rates were higher among service members who were male, Hispanic, in the youngest age groups, in the Army, junior enlisted, and in combat-specific occupations. The rate among recruit/ trainees (779.4 per 10,000 p-yrs) was more than 165 times the rate among all other active component service members (non-recruits) (4.7 per 10,000 p-yrs). Sprains, strains, and contusions accounted for more than one-half of the primary (first-listed) diagnoses associated with combat sports cases. More serious conditions such as concussions/head injuries and skull/face fractures/intracranial injuries were reported among 3.9% and 2.1% of all cases and were more common among boxing-related cases. Hand/wrist fractures were also common among boxing cases. Wrestling had comparatively greater proportions of dislocations and open wounds. Although the combat sport training provides many physical and mental benefits to the individual, safety practices should be enforced to reduce the most frequent and serious injuries.

Genetic programming is a powerful methodology for automatically producing solutions to problems in a variety of domains. It has been used successfully to develop behaviors for RoboCup soccer players and simple combat agents. We will attempt to use genetic programming to solve a problem in the domain of strategic combat, keeping in mind the end goal of developing sophisticated behaviors for compound defense and infiltration. The simplified problem at hand is that of two armed agents in a small room, containing obstacles, fighting against each other for survival. The base case and three changes are considered: a memory of positionsmore » using stacks, context-dependent genetic programming, and strongly typed genetic programming. Our work demonstrates slight improvements from the first two techniques, and no significant improvement from the last.« less

Empathy is one of the main concepts of in social neurosciences. It is defined as a trait with multiple dimensions allowing individuals to place themselves in the emotional states of others. Colombia has an irregular, internal and long-lasting armed conflict which has been increasing its cruelty levels. to assess the empathy dimensions of 285 ex-combatants from the internal Colombian conflict, using the Interpersonal Reactivity Index(IRI) in Spanish. METHODOLOGY AND SUBJECTS: a sample of 285 male ex-combatants, 241 (84, 6%) males: 85,3% paramilitaries, and 14,7% guerillas. The 28 Item IRI questionnaires were administered. 3 exploratory factor analyses (EFA) were performed. Confirmatory factor analyses (CFA) were developed using structural equation procedures. The first EFA obtained 9 factors (KMO=0,74, variance 54,7% and internal consistency (IC): 0,22 - 0,63). The second EFA produced 20 items with burdens above 0,4 and showed a 6-factor structure (KMO=0,70, variance 50,3%, IC: 0,37 - 0,63). The third EFA forced the 4 original IRI dimensions (KMO=0,74, variance 33,77, IC: 0,44 - 0,77. CFAs showed goodness of adjustment indexes adequate for the three models. The 4-factor model obtained the lowest value, while the 6-factor model obtained the highest. The 4- factor model showed the best IC. The Spanish IRI administered to ex-combatants of the Colombian conflict has possible structures of 4, 6 and 9 factors. The best adjustment was for the 6-fctor. The 4-factor model exhibited the best IC. Copyright © 2013 Asociación Colombiana de Psiquiatría. Publicado por Elsevier España. All rights reserved.

This is the first controlled study to explore whether adjunctive immersive virtual reality (VR) can reduce excessive pain of soldiers with combat-related burn injuries during wound debridement. Patients were US soldiers burned in combat attacks involving explosive devices in Iraq or Afghanistan. During the same wound care session using a within-subject experimental design, 12 patients received half of their severe burn wound cleaning procedure (~6 minutes) with standard of care pharmacologies and half while in VR (treatment order randomized). Three 0 to 10 Graphic Rating Scale pain scores for each of the treatment conditions served as the primary variables. Patients reported significantly less pain when distracted with VR. "Worst pain" (pain intensity) dropped from 6.25 of 10 to 4.50 of 10. "Pain unpleasantness" ratings dropped from "moderate" (6.25 of 10) to "mild" (2.83 of 10). "Time spent thinking about pain" dropped from 76% during no VR to 22% during VR. Patients rated "no VR" as "no fun at all" (<1 of 10) and rated VR as "pretty fun" (7.5 of 10). Follow-up analyses showed VR was especially effective for the six patients who scored 7 of 10 or higher (severe to excruciating) on the "worst pain" (pain intensity) ratings. These preliminary results provide the first evidence from a controlled study that adjunctive immersive VR reduced pain of patients with combat-related burn injuries during severe burn wound debridement. Pain reduction during VR was greatest in patients with the highest pain during no VR. These patients were the first to use a unique custom robot-like arm mounted VR goggle system.

Noise-induced hearing loss caused by gunshot in South Korean military service.
Moon, In Seok
2007-04-01
Noise-induced hearing loss is a preventive disease and yet the effective treatment modality has not been established. Acute acoustic traumas caused by an exposure to gunshot noise are common in young South Korean males in military service. Considering the significant lack of awareness on this serious issue as well as the absence of proper protective gear, an in-depth analysis is desperately needed. All 3650 soldiers performed regular periodic gunfire exercise without any hearing protective measures. Seven patients with hearing impairment after periodic gunfire visited the aeromedical squadron; all were right-handed males. Six were tested with the K-2 rifle and one was tested with a K-5 revolver. History taking, physical examination, pure-tone audiometry, and impedance audiometry were conducted. In the next periodic gunfire exercise, all 3650 soldiers performed gunfire with unilateral hearing protection. The average outcome of postexposure air conduction thresholds was 6.5 dB in the right ear and 33.1 dB in the left ear. After medical treatment, hearing impairment was much improved; however, tinnitus was not diminished. In the next periodic gunfire exercise, the result of a supplement of unilateral earplug protection proved its effectiveness on acoustic trauma caused by gunfire noise. Asymmetry in hearing loss is related to the position of the head during gunfire. A unilateral hearing protection device was enough to protect hearing from gunfire noise. At the same time, it can effectively prevent a potential firearm accident that can be caused by trainees mishearing the instruction of a firearm instructor if both earplugs are worn. Thus, providing a unilateral earplug for protection against acoustic trauma must be taken into serious consideration.

The Sound Practice Project is a 5-year study involving baseline evaluation, development, and implementation of musician-specific work health and safety initiatives. A cross-sectional population physical and psychological survey and physical assessment were conducted at the same time, with an auditory health assessment conducted later. The results were used to guide the development of a series of targeted interventions, encompassing physical, psychological, and auditory health components. This paper provides an overview of the project but focuses on the health findings arising from the cross-sectional survey. Three hundred and seventy-seven musicians from the eight professional symphony orchestras in Australia took part in the cross-sectional study (about 70% of eligible musicians). Eighty-four percent (84%) of musicians reported past performance-related musculoskeletal disorder (PRMD) episodes; 50% were suffering a current PRMD. Of the 63% who returned hearing surveys, 43% believed they had hearing loss, and 64% used earplugs at least intermittently. Noise exposure was found to be high in private practice, although awareness of risk and earplug use in this environment was lower than in orchestral settings. Improved strategic approaches, acoustic screens and recently developed active earplugs were found to provide effective new options for hearing protection. With respect to psychosocial screening, female musicians reported significantly more trait anxiety, music performance anxiety, social anxiety, and other forms of anxiety and depression than male musicians. The youngest musicians were significantly more anxious compared with the oldest musicians. Thirty-three percent (33%) of musicians may meet criteria for a diagnosis of social phobia; 32% returned a positive depression screen and 22% for post-traumatic stress disorder (PTSD). PRMDs and trigger point discomfort levels were strongly associated with increasing severity of psychological issues such as depression and music performance anxiety. PMID:25249990

Efficacy of pre-trauma prevention for post-traumatic stress disorder (PTSD) has not yet been established in a randomized controlled trial. Attention bias modification training (ABMT), a computerized intervention, is thought to mitigate stress-related symptoms by targeting disruptions in threat monitoring. We examined the efficacy of ABMT delivered before combat in mitigating risk for PTSD following combat. We conducted a double-blind, four-arm randomized controlled trial of 719 infantry soldiers to compare the efficacy of eight sessions of ABMT (n = 179), four sessions of ABMT (n = 184), four sessions of attention control training (ACT; n = 180), or no-training control (n = 176). Outcome symptoms were measured at baseline, 6-month follow-up, 10 days following combat exposure, and 4 months following combat. Primary outcome was PTSD prevalence 4 months post-combat determined in a clinical interview using the Clinician-Administered PTSD Scale. Secondary outcomes were self-reported PTSD and depression symptoms, collected at all four assessments. PTSD prevalence 4 months post-combat was 7.8% in the no-training control group, 6.7% with eight-session ABMT, 2.6% with four-session ABMT, and 5% with ACT. Four sessions of ABMT reduced risk for PTSD relative to the no-training condition (odds ratio 3.13, 95% confidence interval 1.01-9.22, p < 0.05, number needed to treat = 19.2). No other between-group differences were found. The results were consistent across a variety of analytic techniques and data imputation approaches. Four sessions of ABMT, delivered prior to combat deployment, mitigated PTSD risk following combat exposure. Given its low cost and high scalability potential, and observed number needed to treat, research into larger-scale applications is warranted. The ClinicalTrials.gov identifier is NCT01723215.

Objective To assess the relation between frequency and duration of deployment of UK armed forces personnel on mental health. Design First phase of a cohort study. Setting UK armed forces personnel. Participants Operational history in past three years of a randomly chosen stratified sample of 5547 regulars with experience of deployment. Main outcome measures Psychological distress (general health questionnaire-12), caseness for post-traumatic stress disorder, physical symptoms, and alcohol use (alcohol use disorders identification test). Results Personnel who were deployed for 13 months or more in the past three years were more likely to fulfil the criteria for post-traumatic stress disorder (odds ratio 1.55, 95% confidence interval 1.07 to 2.32), show caseness on the general health questionnaire (1.35, 1.10 to 1.63), and have multiple physical symptoms (1.49, 1.19 to 1.87). A significant association was found between duration of deployment and severe alcohol problems. Exposure to combat partly accounted for these associations. The associations between number of deployments in the past three years and mental disorders were less consistent than those related to duration of deployment. Post-traumatic stress disorder was also associated with a mismatch between expectations about the duration of deployment and the reality. Conclusions A clear and explicit policy on the duration of each deployment of armed forces personnel may reduce the risk of post-traumatic stress disorder. An association was found between deployment for more than a year in the past three years and mental health that might be explained by exposure to combat. PMID:17664192

We assessed the strength of the association of several mental health problems, childhood difficulties, and combat role with anger, as well as the contribution of these factors to explain anger assessed by population attributable fraction (PAF). A total of 9885 UK service personnel, some of them deployed to Iraq and Afghanistan, participated in the study. There was a strong or intermediate association between cases and subthreshold cases of symptoms of posttraumatic stress disorder, psychological distress, multiple physical symptoms and alcohol misuse, having a combat role, childhood adversity, and childhood antisocial behavior with anger. The PAF for any mental health problem and combat role and childhood difficulties was 0.64 (95% confidence interval [CI], 0.56-0.70) and increased to 0.77 (95% CI, 0.69-0.83) if subthreshold cases were included. Anger is a frequent component of mental disorders; health care professionals need to be aware of the interference of anger in the management of mental illness and that anger infrequently presents as an isolated phenomenon.

Objective To determine whether combat-acquired traumatic brain injury (TBI) is associated with post-deployment frequent binge drinking among a random sample of active duty military personnel (ADMP). Participants ADMP who returned home within the past year from deployment to a combat theater of operations and completed a survey health assessment (N = 7,155). Methods Cross-sectional observational study with multivariate analysis of responses to the 2008 Department of Defense Survey of Health Related Behaviors among Active Duty Military Personnel, an anonymous, random population-based assessment of the Armed Forces. Main Measures Frequent binge drinking: five or more drinks on the same occasion, at least once per week, in the past 30 days. TBI-AC: self-reported altered consciousness only; loss of consciousness of less than 1 minute (TBI-LOC<1); and LOC of 1 minute or greater (TBI-LOC 1+) after combat injury event exposure. Results Of ADMP who had a past year combat deployment, 25.6% were frequent binge drinkers and 13.9% reported experiencing a TBI on the deployment, primarily TBI-AC (7.5%). In regression models adjusting for demographics and positive screen for posttraumatic stress disorder, ADMP with TBI had increased odds of frequent binge drinking compared to those with no injury exposure or without TBI: TBI-AC (AOR 1.48, 95% CI, 1.18–1.84); TBI-LOC 1+ (AOR 1.67, 95% CI, 1.00–2.79). Conclusions TBI was significantly associated with past month frequent binge drinking after controlling for posttraumatic stress disorder, combat exposure, and other covariates. PMID:22955100

Estimation of Dog-Bite Risk and Related Morbidity Among Personnel Working With Military Dogs.
Schermann, H; Eiges, N; Sabag, A; Kazum, E; Albagli, A; Salai, M; Shlaifer, A
Soldiers serving in the Israel Defense Force Military Working Dogs (MWD) Unit spend many hours taming dogs' special skills, taking them on combat missions, and performing various dogkeeping activities. During this intensive work with the aggressive military dogs, bites are common, and some of them result in permanent disability. However, this phenomenon has not been quantified or reported as an occupational hazard. This was a retrospective cohort study based on self-administered questionnaires. Information was collected about soldiers' baseline demographics, duration of the experience of working with dogs, total number of bites they had, circumstances of bite events, and complications and medical treatment of each bite. Bite risk was quantified by incidence, mean time to first bite, and a Cox proportional hazards model. Rates of complications and the medical burden of bites were compared between combat soldiers and noncombat dogkeepers. Bite locations were presented graphically. Seventy-eight soldiers participated and reported on 139 bites. Mean time of working with dogs was 16 months (standard deviation, ±9.4 months). Overall bite incidence was 11 bites per 100 person-months; the mean time to first bite event was 6.3 months. The Cox proportional hazards model showed that none of baseline characteristics significantly increased bite hazard. About 90% of bites occurred during routine activities, and 3.3% occurred on combat missions. Only in 9% of bite events did soldiers observed the safety precautions code. Bite complications included fractures, need for intravenous antibiotic treatment and surgical repair, prominent scarring, diminished sensation, and stiffness of proximal joints. Bite complications were similar between combat soldiers and dogkeepers. Most bites (57%) were located on hands and arms. MWD bites are an occupational hazard resulting in significant medical burden. Hands and arms were most common bite locations. Observance of safety precautions may be the most appropriate first-line preventive intervention. Barrier protection of upper extremities may reduce bite severity and complication rates. 2017.

Conductive hearing loss (CHL) is known to produce hearing deficits, including deficits in sound localization ability. The differences in sound intensities and timing experienced between the two tympanic membranes are important cues to sound localization (ILD and ITD, respectively). Although much is known about the effect of CHL on hearing levels, little investigation has been conducted into the actual impact of CHL on sound location cues. This study investigated effects of CHL induced by earplugs on cochlear microphonic (CM) amplitude and timing and their corresponding effect on the ILD and ITD location cues. Acoustic and CM measurements were made in 5 chinchillas before and after earplug insertion, and again after earplug removal using pure tones (500 Hz to 24 kHz). ILDs in the unoccluded condition demonstrated position and frequency dependence where peak far-lateral ILDs approached 30 dB for high frequencies. Unoccluded ear ITD cues demonstrated positional and frequency dependence with increased ITD cue for both decreasing frequency (±420 μs at 500 Hz, ±310 μs for 1-4 kHz) and increasingly lateral sound source locations. Occlusion of the ear canal with foam plugs resulted in a mild, frequency-dependent conductive hearing loss of 10-38 dB (mean 31 ± 3.9 dB) leading to a concomitant frequency dependent increase in ILDs at all source locations. The effective ITDs increased in a frequency dependent manner with ear occlusion as a direct result of the acoustic properties of the plugging material, the latter confirmed via acoustical measurements using a model ear canal with varying volumes of acoustic foam. Upon ear plugging with acoustic foam, a mild CHL is induced. Furthermore, the CHL induced by acoustic foam results in substantial changes in the magnitudes of both the ITD and ILD cues to sound location. Copyright © 2010 Elsevier B.V. All rights reserved.

Crippling Violence: Conflict and Incident Polio in Afghanistan.
Norris, Alison; Hachey, Kevin; Curtis, Andrew; Bourdeaux, Margaret

Designing effective public health campaigns in areas of armed conflict requires a nuanced understanding of how violence impacts the epidemiology of the disease in question. We examine the geographical relationship between violence (represented by the location of detonated Improvised Explosive Devices) and polio incidence by generating maps of IEDs and polio incidence during 2010, and by comparing the mean number of IED detonations in polio high-risk districts with non polio high-risk districts during 2004-2009. We demonstrate a geographic relationship between IED violence and incident polio. Districts that have high-risk for polio have highly statistically significantly greater mean numbers of IEDs than non polio high-risk districts (p-values 0.0010-0.0404). The geographic relationship between armed conflict and polio incidence provides valuable insights as to how to plan a vaccination campaign in violent contexts, and allows us to anticipate incident polio in the regions of armed conflict. Such information permits vaccination planners to engage interested armed combatants to co-develop strategies to mitigate the effects of violence on polio.
Postdischarge Cause-of-Death Analysis of Combat-Related Burn Patients
Escolas, Sandra M.; Orman, Jean A.; Chung, Kevin K.; Renz, Evan M.
2017-01-01
Combat operations in Iraq and Afghanistan have resulted in up to 8.8% of combat-related casualties suffering burns. From World War I through Desert Storm, burns have been associated with approximately 4% of the combat-related deaths. Experiencing a blast injury and exposure to killing and death while deployed has been shown to increase suicide risk. Although several studies of military populations have investigated risk factors for death among burn patients during the acute phase, no studies have reported mortality rates, cause-of-death, or the prevalence of suicide after hospital discharge. This study examined the case fatality rate, causes of death, and the prevalence of suicide among 830 combat burn patients discharged from the sole burn center in the U.S. Department of Defense, between March 7, 2003 and March 6, 2013. Cause-of-death was determined through the Armed Forces Medical Examiner’s Office and the Office of the Secretary of Defense’s National Death Index. A total of 11 deaths occurred among the 830 burn survivors, for an overall case fatality rate of 1.3%. Of the 11 who died, five deaths were related to accidental poisoning by exposure to drugs; three were related to operations of war (two after returning to the war zone), and the remaining three died from other accidental causes (one explosion and two vehicle crashes). There was no indication of suicide or suspicion of suicide as a cause-of-death for the former patients included in this study, suggesting that combat burn injury did not appear to increase the risk of death by suicide in our study population. Further research is needed to understand the factors that contribute to the apparent resilience of combat burn survivors. PMID:26629656
Depression in Female Veterans Returning from Deployment: The Role of Social Factors.
Sairsingh, Holly; Solomon, Phyllis; Helstrom, Amy; Treglia, Dan
2018-03-01
Women are serving in the armed forces and deployed to areas of conflict in increasing numbers. Problems such as depressive symptoms and risks related to combat exposure can have negative effects on adjustment following service; understanding the relationship between these problems may contribute to strategies providers can use to facilitate healthy adjustment after deployment. The purpose of this study is to examine social factors as they relate to mental health adjustment, namely depressive symptoms among female veterans who served in Iraq and Afghanistan as part of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OND). We hypothesized that combat exposure would predict higher levels of depressive symptoms and that social support would moderate the relationship between combat exposure and depression. In a cross-sectional design, 128 female Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans completed an online survey about combat experience, social support, depression, demographic characteristics, and behavioral health symptom history. We conducted multiple regression analyses to examine linear and moderating relationships. There was no significant relationship between combat exposure and depression; social support did not significantly moderate the relationship between combat exposure and depression. However, higher levels of social support and financial comfort were significantly related to lower levels of depression. This study highlights the role of social factors, specifically social support and perceived financial status, as potential barriers to healthy emotional readjustment following deployment. These findings suggest that it may be beneficial for mental health providers to screen female veterans and refer them to appropriate services to reduce financial stressors and strengthen their use of social support. More research should continue to examine more fully the impact of combat exposure on female service members' mental health and work to isolate the factors most strongly related to depression.

To determine whether combat-acquired traumatic brain injury (TBI) is associated with postdeployment frequent binge drinking among a random sample of active duty military personnel. Active duty military personnel who returned home within the past year from deployment to a combat theater of operations and completed a survey health assessment (N = 7155). Cross-sectional observational study with multivariate analysis of responses to the 2008 Department of Defense Survey of Health Related Behaviors Among Active Duty Military Personnel, an anonymous, random, population-based assessment of the armed forces. Frequent binge drinking: 5 or more drinks on the same occasion, at least once per week, in the past 30 days. TBI-AC: self-reported altered consciousness only; loss of consciousness (LOC) of less than 1 minute (TBI-LOC <1); and LOC of 1 minute or greater (TBI-LOC 1+) after combat injury event exposure. Of active duty military personnel who had a past year combat deployment, 25.6% were frequent binge drinkers and 13.9% reported experiencing a TBI on the deployment, primarily TBI-AC (7.5%). In regression models adjusting for demographics and positive screen for posttraumatic stress disorder, active duty military personnel with TBI had increased odds of frequent binge drinking compared with those with no injury exposure or without TBI: TBI-AC (adjusted odds ratio, 1.48; 95% confidence interval, 1.18-1.84); TBI-LOC 1+ (adjusted odds ratio, 1.67; 95% confidence interval, 1.00-2.79). Traumatic brain injury was significantly associated with past month frequent binge drinking after controlling for posttraumatic stress disorder, combat exposure, and other covariates.
Trauma Care Training for National Police Nurses in Colombia
Rubiano, Andrés M.; Sánchez, Álvaro I.; Guyette, Francis; Puyana, Juan C.
2010-01-01
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

The analysis of the distribution of gunshot injuries in a sample of 777 sets of human remains of proven human rights abuse from Somaliland, the Balkans and Peru is compared to frequencies of injuries sustained by combatants in contemporary conflicts reported in the literature. Principal Component Analysis (PCA) reduced the data to three components accounting for 82.94% of the variance. The first component with 38.31% of variance shows segments Arms and thorax/abdomen to be positively correlated (0.887 and 0.662, respectively); the segment head/neck is strongly correlated (0.951) to the second component while the segment thorax/abdomen shows a low, negative correlation (-0.388). Finally in the third component only the legs are strongly correlated (0.991). Data was further subjected to a K-means cluster analysis to determine the likely groupings combining the four types of injuries. Each of the three clusters reproduced similar patterns observed in the PCA: Cluster 1 shows the prevalence of injuries to the thorax/abdomen and extremities in addition to injuries to the head/neck; Cluster 2 shows injuries to the head/neck and Cluster 3 injuries to the thorax/abdomen and a lower representation of the arms and legs. Most of the cases (70.5%), irrespective of geography and type of site (attack or detention), were grouped into Cluster 2. Such comparison shows that in human rights abuse, irrespective of their geography, gunshot injuries tend to follow a pattern favouring the head/neck and thorax/abdomen areas over the extremities, the reverse pattern observed in contemporary combat operations. In those settings gunshot wound trauma is the second cause of mortality/morbidity (after fragmenting ammunition) and its distribution concentrates on the extremities, thorax/abdomen and head; following the pattern of protective armour when it is used. Considering that human rights abuses are often presented as encounters between two armed groups in the context of counter-insurgency operations, a careful analysis of gunshot injury patterns could serve as an indicator that in fact murder, rather than combat, took place and the intention was to kill rather than to maim or render people unfit for battle. To compare the variation of gunshot injury patterns between mortality associated with human rights abuses and armed conflict in selected samples from different countries. Literature review and case analysis.

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.

Emotional processing (EP) is a complex cognitive function necessary to successfully adjust to social environments where we need to interpret and respond to cues that convey threat or reward signals. Ex-combatants have consistently shown atypical EP as well as poor social interactions. Available reintegration programs aim to facilitate the re-adaptation of ex-combatants to their communities. However, they do not incorporate actions to improve EP and to enhance cognitive-emotional regulation. The present study was aimed at evaluating the usefulness of an intervention focused on Social Cognitive Training (SCT), which was designed to equip ex-combatants enrolled in the Social Reintegration Route with EP and social cognition skills. A group of 31 ex-combatants (mean age of 37.2, 29 men) from Colombian illegal armed groups were recruited into this study. Of these, 16 were invited to take part in a SCT and the other continued with the conventional reintegration intervention. Both groups underwent 12 training sessions in a period 12–14 weeks. They were assessed with a comprehensive protocol which included Psychosocial, Behavioral, and Emotion Processing instruments. The scores on these instruments prior to and after the intervention were compared within and between groups. Both groups were matched at baseline. Ex-combatants receiving the SCT experienced significant improvements in EP and a reduction in aggressive attitudes, effects not observed in those continuing the conventional reintegration intervention. This is the first study that achieves such outcomes in such a population using SCT intervention. We discuss the implications of such results toward better social reintegration strategies.

The present study was aimed at evaluating the usefulness of an intervention focused on Social Cognitive Training (SCT), which was designed to equip ex-combatants enrolled in the Social Reintegration Route with EP and social cognition skills. A group of 31 ex-combatants (mean age of 37.2, 29 men) from Colombian illegal armed groups were recruited into this study. Of these, 16 were invited to take part in a SCT and the other continued with the conventional reintegration intervention. Both groups underwent 12 training sessions in a period 12-14 weeks. They were assessed with a comprehensive protocol which included Psychosocial, Behavioral, and Emotion Processing instruments. The scores on these instruments prior to and after the intervention were compared within and between groups. Both groups were matched at baseline. Ex-combatants receiving the SCT experienced significant improvements in EP and a reduction in aggressive attitudes, effects not observed in those continuing the conventional reintegration intervention. This is the first study that achieves such outcomes in such a population using SCT intervention. We discuss the implications of such results toward better social reintegration strategies.

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.

The author of this article--Chief of the Russian Armed Forces Medical Service--analyses the trends of optimization of medical support of the Army and Navy, taking into account the experience of combat casualty care during Chechen crisis. In order to enhance the efficiency of medical support during combat activities all the personnel is supplied with first-aid kits. Each company is reinforced with a medical assistant or army physician; battalion medical posts--with physicians, medical assistants, aidmen, mobile dressing room and ambulances; regiment medical posts--with two surgeons, an anaesthesiologist, an instrument nurse and nurse-anaesthetist. The primary medical care is provided at the battalion medical post; qualified (secondary) surgical care--at regiment medical posts, and specialized (tertiary) medical care--at special medical detachments (SMD) and military hospitals. The wounded are evacuated from the zone of combat actions by APC or MICV, and then by helicopters. The further evacuation of wounded is realized by transport or medical aircraft, including "Skalpel" flight surgery plane. The experience of army physicians has proved the necessity of multilateral development of Mobile Forces Medical Service and the formation of aeromobile hospitals. An airborne infantry battalion must have a medical company in its organic structure, and respectively a separate medical battalion must have an aeromobile medical company. The SMD which are assigned to act in the emergency situations of peaceful time also can be effective in providing medical care (including specialized care) during local military conflicts. Thinking over the further development of medical support in the Armed Forces the author assigns a number of tasks throughout all the chain of medical command, including medical establishments, medical examination boards, the Corps of Senior medical specialists (in surgery, internal medicine, pathologicoanatomy, sanitary supervision, etc). A special attention is paid to the formation of an efficient system of sanitary-epidemiological supervision in the Armed Forces; the improvement of medical assistance for servicewomen, retired officers and their dependents; the enforcement of military and labour discipline in the units and establishments of medical service; training and education of medical personnel; the strict adherence to the principles of medical ethics, deontology, and oath of physician.

Using a dialogical narrative approach, this original research explored how combat veterans experiencing post-traumatic stress disorder made sense of peer relationships with other veterans and what effects these relationships had on their well-being. Interviews and participant observations were conducted with 15 male combat veterans (aged 27-60 years) and one member of the civilian emergency services, the majority of whom were diagnosed with post-traumatic stress disorder following traumatic exposure in a range of armed conflicts. All participants were part of a surfing charity for veterans experiencing post-traumatic stress disorder. Data were rigorously analysed using a dialogical narrative analysis (DNA). Findings revealed the collective story that veterans used to make sense of peer relationships within the group. This collective story worked for the veterans to shape their experiences of well-being by fostering camaraderie, stimulating deeper connections and countering the negative effects of post-traumatic stress disorder. Potential therapeutic effects of the collective story were also identified. This article extends previous knowledge on combat veterans and social relationships and advances the field of narrative health psychology through the empirical application of a sophisticated dialogical narrative approach. © The Author(s) 2015.
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
Winds of War: Enhancing Civilian and Military Partnerships to Assure Readiness: White Paper.
Schwab, C William
2015-08-01
This White Paper summarizes the state of readiness of combat surgeons and provides action recommendations that address the problems of how to train, sustain, and retain them for future armed conflicts. As the basis for the 2014 Scudder Oration, I explored how to secure an improved partnership between military and civilian surgery, which would optimize learning platforms and embed military trauma personnel at America's academic medical universities for trauma combat casualty care (TCCC). To craft and validate these recommendations, I conducted an integrative and iterative process of literature reviews, interviews of military and civilian leaders, and a survey of military-affiliated surgeons. The recommended action points advance the training of combat surgeons and their trauma teams by creating an expanded network of TCCC training sites and sourcing the cadre of combat-seasoned surgeons currently populating our civilian and military teaching hospitals and universities. The recommendation for the establishment of a TCCC readiness center or command within the Medical Health System of the Department of Defense includes a military and civilian advisory board, with the reformation of a think tank of content experts to address high-level solutions for military medicine, readiness, and TCCC.

In Israel, the Airborne Rescue and Evacuation Unit (AREU) provides prehospital trauma care in times of peace and during times of armed conflict. In peacetime, the AREU transports children who were involved in motor vehicle collisions (MVC) and those who fall off cliffs (FOC). During armed conflict, the AREU evacuates children who sustain firearm injuries (FI) from the fighting zones. To report on prehospital injury severity of children who were evacuated by the AREU from combat zones. A retrospective comparative analysis was conducted on indicators of prehospital injury severity for patients who had MVC, FOC, and FI. It included the National Advisory Committee for Aeronautics (NACA) score, the Glasgow Coma Scale (GCS) score on scene, and the number of procedures performed by emergency medical personnel and by the AREU air-crew. From January 2003 to December 2009, 36 MVC, 25 FOC, and 17 FI children were transported from the scene by the AREU. Five patients were dead at the scene: 1 (2.8%) MVC, 1 (4%) FOC, and 3 (17.6%) FI. Two (11.7%) FI patients were dead on arrival at the hospital. MVC, FOC, and FI patients had mean (±SD) NACA scores of 4.4 ± 1.2, 3.6 ± 1.2, and 5 ± 0.7, respectively. Mean (±SD) GCS scores were 8.9 ± 5.6, 13.6 ± 4, and 6.9 ± 5.3, respectively. Life support interventions were required by 29 (80.6%) MVC, 3 (12%) FOC, and 15 (88.2%) FI patients. In the prehospital setting, children evacuated from combat zones were more severely injured than children who were transported from the scene during peacetime. Copyright © 2013 Elsevier Inc.

A dynamic model for generating actuator specifications for small arms barrel active stabilization
NASA Astrophysics Data System (ADS)
Pathak, Anupam; Brei, Diann; Luntz, Jonathan; Lavigna, Chris
2006-03-01
Due to stresses encountered in combat, it is known that soldier marksmanship noticeably decreases regardless of prior training. Active stabilization systems in small arms have potential to address this problem to increase soldier survivability and mission effectiveness. The key to success is proper actuator design, but this is highly dependent on proper specification which is challenging due to the human/weapon interaction. This paper presents a generic analytical dynamic model which is capable of defining the necessary actuation specifications for a wide range of small arms platforms. The model is unique because it captures the human interface--shoulder and arm--that introduces the jitter disturbance in addition to the geometry, inertial properties and active stabilization stiffness of the small arms platform. Because no data to date is available for actual shooter-induced disturbance in field conditions, a method is given using the model to back-solve from measured shooting range variability data the disturbance amplitude information relative to the input source (arm or shoulder). As examples of the applicability of the model to various small arms systems, two different weapon systems were investigated: the M24 sniper weapon and the M16 assault rifle. In both cases, model based simulations provided valuable insight into impact on the actuation specifications (force, displacement, phase, frequency) due to the interplay of the human-weapon-active stabilization interface including the effect of shooter-disturbance frequency, disturbance location (shoulder vs. arm), and system parameters (stiffness, barrel rotation).
[Endovascular surgery in the war].
Reva, V A; Samokhvalov, I M
2015-01-01
Rapid growth of medical technologies has led to implementation of endovascular methods of diagnosis and treatment into rapidly developing battlefield surgery. This work based on analysing all available current publications generalizes the data on using endovascular surgery in combat vascular injury. During the Korean war (1950-1953) American surgeons for the first time performed endovascular balloon occlusion of the aorta - the first intravascular intervention carried out in a zone of combat operations. Half a century thereafter, with the beginning of the war in Afghanistan (2001) and in Iraq (2003) surgeons of central hospitals of the USA Armed Forces began performing delayed endovascular operations to the wounded. The development of technologies, advent of mobile angiographs made it possible to later on implement high-tech endovascular interventions in a zone of combat operations. At first, more often they performed implantation of cava filters, somewhat afterward - angioembolization of damaged accessory vessels, stenting and endovascular repair of major arteries. The first in the theatre of war endovascular prosthetic repair of the thoracic aorta for severe closed injury was performed in 2008. Russian experience of using endovascular surgery in combat injuries is limited to diagnostic angiography and regional intraarterial perfusion. Despite the advent of stationary angiographs in large hospitals of the RF Ministry of Defence in the early 1990s, endovascular operations for combat vascular injury are casuistic. Foreign experience in active implementation of endovascular technologies to treatment of war-time injuries has substantiated feasibility of using intravascular interventions in tertiary care military hospitals. Carrying out basic training courses on endovascular surgery should become an organic part of preparing multimodality general battlefield surgeons rendering care on the theatre of combat operations.
Crippling Violence: Conflict and Incident Polio in Afghanistan
Norris, Alison; Hachey, Kevin; Curtis, Andrew; Bourdeaux, Margaret

Background Designing effective public health campaigns in areas of armed conflict requires a nuanced understanding of how violence impacts the epidemiology of the disease in question. Methods We examine the geographical relationship between violence (represented by the location of detonated Improvised Explosive Devices) and polio incidence by generating maps of IEDs and polio incidence during 2010, and by comparing the mean number of IED detonations in polio high-risk districts with non polio high-risk districts during 2004–2009. Results We demonstrate a geographic relationship between IED violence and incident polio. Districts that have high-risk for polio have highly statistically significantly greater mean numbers of IEDs than non polio high-risk districts (p-values 0.0010–0.0404). Conclusions The geographic relationship between armed conflict and polio incidence provides valuable insights as to how to plan a vaccination campaign in violent contexts, and allows us to anticipate incident polio in the regions of armed conflict. Such information permits vaccination planners to engage interested armed combatants to co-develop strategies to mitigate the effects of violence on polio. PMID:26958854

Two faces of death: fatalities from disease and combat in America's principal wars, 1775 to present.
Cirillo, Vincent J
2008-01-01
Throughout America's first 145 years of war, far more of the country's military personnel perished from infectious diseases than from enemy action. This enduring feature of war was finally reversed in World War II, chiefly as a result of major medical advances in prevention (vaccines) and treatment (antibiotics). Safeguarding the health of a command is indispensable for the success of any campaign. Wars are lost by disease, which causes an enormous drain on the military's resources and affects both strategy and tactics. Disease and combat mortality data from America's principal wars (1775-present) fall into two clearly defined time periods: the Disease Era (1775-1918), during which infectious diseases were the major killer of America's armed forces, and the Trauma Era (1941-present), in which combat-related fatalities predominated. The trend established in World War II continues to the present day. Although there are currently more than 3,400 U.S. military fatalities in Iraq, the disease-death toll is so low that it is exceeded by the number of suicides.
Growing up in armed groups: trauma and aggression among child soldiers in DR Congo
Hermenau, Katharin; Hecker, Tobias; Maedl, Anna; Schauer, Maggie; Elbert, Thomas
2013-01-01
Background Child soldiers are often both victims and perpetrators of horrendous acts of violence. Research with former child soldiers has consistently shown that exposure to violence is linked to trauma-related disorders and that living in a violent environment is correlated with enhanced levels of aggression. Objective To gain more insight into the experiences and the mental health status of former child soldiers, we conducted a survey with N=200 former child soldiers and adult combatants in the DR Congo. Methods We conducted semi-structured interviews concerning military experiences, experienced and perpetrated violence, and mental health. Results Former child soldiers reported more experienced and perpetrated violence, a greater severity of trauma-related suffering, as well as higher appetitive aggression than adult ex-combatants. Appetitive aggression was related to more perpetrated violence, higher military ranks, voluntary recruitment and higher rates of reenlistments in former child soldiers. Conclusions Our results indicate that growing up in an armed group is related to higher levels of trauma-related disorders and aggressive behavior. This may explain the challenge of reintegrating former child soldiers. It is thus important to consider mental health problems, particularly trauma-related disorders and aggressive behavior, of former child soldiers for designing adequate reintegration programs.

There were investigated 453 servicemen--participants of fighting actions in Chechnya [correction of Chechenskaya] Republic in whom the incidence of psychologic stress reactions nearly twice exceeded disorders of other types of psychic dysfunction. 5 groups of combatants were selected and severity of psychic disorders depending on duration of participation in fighting actions was determined. Posttraumatic stress disorders were revealed in 14.5% of servicemen, no signs of psychologic desadaptation were detected in 16.6%, 16.9% had pathologic psychogenic reactions, 18.6% showed pathologic level of psychic disorders, and psychologic stress reactions were noted in 33.4%. The developed individual programs of medico-psychologic rehabilitation depending on type and severity of psychic disorders will allow to reduce the period of restorative treatment and significantly decrease servicemen discharge from the Armed Forces because of psychic disorders.
Did a "lucky shot" sink the submarine H.L. Hunley?
Lance, Rachel M; Warder, Henry; Bass, Cameron R Dale
2017-01-01
The H.L. Hunley was the first submarine to be successful in combat, sinking the Union vessel Housatonic outside Charleston Harbor in 1864 during the Civil War. However, despite marking a milestone in military history, little is known about this vessel or why it sank. One popular theory is the "lucky shot" theory: the hypothesis that small arms fire from the crew of the Housatonic may have sufficiently damaged the submarine to sink it. However, ballistic experiments with cast iron samples, analysis of historical experiments firing Civil War-era projectiles at cast iron samples, and calculation of the tidal currents and sinking trajectory of the submarine indicate that this theory is not likely. Based on our results, the "lucky shot" theory does not explain the sinking of the world's first successful combat submarine. Published by Elsevier B.V.

Returning home: resettlement of formerly abducted children in Northern Uganda.
Corbin, Joanne N
2008-06-01
This exploratory qualitative study considers the subjective resettlement experiences of children forced into armed conflict in Northern Uganda from the perspectives of 11 former child combatants and 11 adult community members. A thematic analysis was performed on the narrative data. The bioecological model was used to provide a conceptual framework for key themes. Major findings included the overarching impact of ongoing armed conflict on returnees' lives, the important role of the family in supporting children's resettlement, the harassment of former child soldiers by community members, and the community's inability to support systematically the returning children in tangible ways. This study recommends that humanitarian services at all levels strengthen the capacity of families to care for the material and psychoemotional needs of former child soldiers within their communities.

Sexual violence in armed conflict: the least condemned of war crimes.
O'Connor, Mike
2014-03-01
Sexual violence in armed conflict has traditionally received poor attention until recent years. It has been the "least condemned of war crimes" although, with the inception of the International Criminal Court and various other international courts and tribunals, convictions of high-profile aggressors are increasing. Only recently Charles Taylor, the President of Liberia, was convicted of war crimes and crimes against humanity which included rape and sexual slavery. He was sentenced to 50 years imprisonment. Is prosecution of these crimes sufficient to minimise sexual violence in war? That seems unlikely given the potential for such violence to be a cheap and effective strategy to terrorise a civilian population and "ethnically cleanse" the newly won territory. However, there is a remarkable variation in the levels of sexual violence in armed conflicts. Some, such as the Israeli-Palestinian conflict, have extremely low levels, whereas in Bosnia and many African states the prevalence of sexual violence is at epidemic levels. The reasons for such differences are many, however, some precipitating factors may be improved by strong military discipline, improved gender balance in armed forces, better political awareness by combatants of the aims of a campaign and pre-deployment ethical training.

There is a ubiquitous and never ending need in the US armed forces for training materials that provide the warfighter with the skills needed to differentiate between friendly and enemy forces on the battlefield. The current state of the art in battlefield identification training is the Recognition of Combat Vehicles (ROCV) tool created and maintained by the Communications - Electronics Research, Development and Engineering Center Night Vision and Electronic Sensors Directorate (CERDEC NVESD). The ROC-V training package utilizes measured visual and thermal imagery to train soldiers about the critical visual and thermal cues needed to accurately identify modern military vehicles and combatants. This paper presents an approach that has been developed to augment the existing ROC-V imagery database with synthetically generated multi-spectral imagery that will allow NVESD to provide improved training imagery at significantly lower costs.

Two operational-and-tactical factors had the main influence on organization of the surgical care rendered to the casualties on the Northern Caucasus: the fulminant and maneuverable nature of combat operations at the beginning of both armed conflicts and rather small territory of war theatre. The main special features of organization of surgical care to the casualties were the use of Medical Squads of Special Purpose in the combat conditions and maximal approximation of the specialized surgical care to the wounded by echelonment of medical units and wide use of helicopter evacuation. The structure of sanitary losses was characterized by the increase in the frequency of mechanical traumas, thermal and combined injuries, by the high share of the casualties with head injuries. Besides the number of seriously wounded and critical casualties has increased.

1987-06-01
The military gear delivered from the US in the Iran-contra affair represents only a minor portion of arms sales to the combatants in the Iraq-Iran war. That war has now lasted more than six years and has deeply influenced the international arms market. Occurring during a period when other demand for arms has been relatively low, the war has nourished new suppliers and has revived both the legal and illegal private arms market. The erratic behavior of the USSR and the US, until recently by far the most important arms suppliers to the Third World, has pushed Iran and Iraqmore » toward more commercially oriented sources, including many in the Third World. Both countries have had ample supplies of weapons during the war, and these weapons have served their purpose. Mainly because of its duration, the war already ranks third among post-World War II wars - after the Vietnam war and the Biafra war - in battlefield victims, with 300,000-500,000 casualties. The economic cost has risen to nearly $500 billion in weapons, destruction, and lost income. While it is hard to see anything but losers on the battlefield, the arms traffickers are profiting. Total Iranian arms imports since August 1980 have been higher than $10 billion, while Iraq has imported more than $30 billion worth. It is difficult to know whether making arms more difficult to obtain would have stopped the war, but judging from other recent wars, such as those between India and Pakistan, between Uganda and Tanzania, and in the Middle East, it seems likely that hostilities could have been stopped long ago. 12 references.« less

The authors analyze new legal regulatory document--Medical equipment and reserves supply rate for military units and organisations of the Armed Forces of the Russian Federation, developed in the process of modernization of the system of medical equipment rationing for military units. New legal regulatory document was developed with the aim to replace the similar document d.d 1996-1997. The authors came to conclusion that costs of new medical equipment and reserves supply rates are similar to previous rates. At the same time costs new medical equipment supply rates for medical service increased more than 25%. It is related to change of the role of medical service in the system of medical supply of the Armed Forces of the Russian Federation. Modernization of the system of medical equipment supply rates for military unit of the Armed Forces of the Russian Federation, performed for the purpose of medical supplement for military unit in accordance with new state of the Armed Forces of the Russian Federation, allowed to actualize the regulatory framework of medical supply by means of development and adoption of new Supply and reserves rates be the Ministry of defence. Use if these rates will increase effectiveness and quality of medical supply during the wartime, provide a commonality of reserves of medical equipment and maintenance of established level of combat readiness of medical service of the Armed Forces of the Russian Federation.
Embracing a Revolution - Telemedicine.
Dheer, Ajay; Chaturvedi, R K
2005-01-01
The recent advances in information and communication technologies offer real and practical opportunities to health professionals to share expertise and resources in health care over distances. For a country like India with pockets of medical excellence surrounded by a vast number of badly equipped hospitals with limited specialists, telemedicine could revolutionize health care. The potential of telemedicine seem to be vital in avoiding the frame of travel, in timely getting specialist advise to remote areas, minimizing the cost and of course an opportunity to learn from each other. In developed countries the technological advancement and research aims primarily to satiate the needs of their armed forces and to ensure tactical and technical supremacy. The medical community in the Indian Armed Forces should harness the technologies and embrace this revolution of the information age to provide world class combat casualty care.

Introduction. Although quarry operations have high economic significance, the effects they cause to the workers in terms of excessive noise production cannot be overlooked. This cross-sectional study assessed the extent of noise exposure and its influence on hearing capabilities among quarry workers in Ashanti region. Methods. The study involved 400 workers randomly selected from five quarries in Ashanti region from April to June 2012. Data was collected using structured questionnaires, physical examination, and audiological assessments. A logistic regression model was fitted to assess independent predictors of hearing loss. Results. All the machines used at the various quarries produced noise that exceeded the minimum threshold with levels ranging from 85.5 dBA to 102.7 dBA. 176 (44%) of study respondents had hearing threshold higher than 25 dBA. 18% and 2% of these were moderately (41–55 dBA) and severely (71–90 dBA) impaired, respectively. Age, duration of work, and use of earplugs independently predicted the development of hearing loss. Use of earplugs showed a protective effect on the development of hearing loss (OR = 0.45; 95% CI = 0.25, 0.84). Conclusion. This study provides empirical evidence on the extent of damage caused to quarry workers as a result of excessive noise exposure. This will support the institution of appropriate protective measures to minimize this threat. PMID:26904137

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

Third Location Decompression (TLD) is an activity undertaken by UK Armed Forces (UK AF) personnel at the end of an operational deployment which aims to smooth the transition between operations and returning home. We assessed whether TLD impacted upon both mental health and postdeployment readjustment. Data collected during a large cohort study was examined to identify personnel who either engaged in TLD or returned home directly following deployment. Propensity scores were generated and used to calculate inverse probability of treatment weights in adjusted regression analyses to compare mental health outcomes and postdeployment readjustment problems. TLD had a positive impact upon mental health outcomes (post-traumatic stress disorder (PTSD) and multiple physical symptoms) and levels of harmful alcohol use. However, when the samples were stratified by combat exposure, although postdeployment readjustment was similar for all exposure levels, personnel experiencing low and moderate levels of combat exposure experienced the greatest positive mental health effects. We found no evidence to suggest that TLD promotes better postdeployment readjustment; however, we found a positive impact upon alcohol use and mental health with an interaction with degree of combat exposure. This study suggests that TLD is a useful postdeployment transitional activity that may help to improve PTSD symptoms and alcohol use in UK AF personnel.

Background Warring groups that compete to dominate a civilian population confront contending behavioral options: target civilians or battle the enemy. We aimed to describe degrees to which combatant groups concentrated lethal behavior into intentionally targeting civilians as opposed to engaging in battle with opponents in contemporary armed conflict. Methodology/Principal Findings We identified all 226 formally organized state and non-state groups (i.e. actors) that engaged in lethal armed conflict during 2002–2007: 43 state and 183 non-state. We summed civilians killed by an actor's intentional targeting with civilians and combatants killed in battles in which the actor was involved for total fatalities associated with each actor, indicating overall scale of armed conflict. We used a Civilian Targeting Index (CTI), defined as the proportion of total fatalities caused by intentional targeting of civilians, to measure the concentration of lethal behavior into civilian targeting. We report actor-specific findings and four significant trends: 1.) 61% of all 226 actors (95% CI 55% to 67%) refrained from targeting civilians. 2.) Logistic regression showed actors were more likely to have targeted civilians if conflict duration was three or more years rather than one year. 3.) In the 88 actors that targeted civilians, multiple regressions showed an inverse correlation between CTI values and the total number of fatalities. Conflict duration of three or more years was associated with lower CTI values than conflict duration of one year. 4.) When conflict scale and duration were accounted for, state and non-state actors did not differ. We describe civilian targeting by actors in prolonged conflict. We discuss comparable patterns found in nature and interdisciplinary research. Conclusions/Significance Most warring groups in 2002–2007 did not target civilians. Warring groups that targeted civilians in small-scale, brief conflict concentrated more lethal behavior into targeting civilians, and less into battles, than groups in larger-scale, longer conflict.

Limited data exist examining the use of fecal diversion in combatants from modern armed conflicts. Characterization of factors leading to colostomy creation is an initial step toward optimizing and individualizing combat casualty care. A retrospective review of the US Department of Defense Trauma Registry database was performed for all US and coalition troops with colorectal injuries sustained during combat operations in Iraq and Afghanistan over 8 years. Colostomy rate, anatomic injury location, mechanism of injury, demographic data, and initial physiologic parameters were examined. Univariate and multivariate analyses were conducted. We identified 867 coalition military personnel with colorectal injuries. The overall colostomy rate was 37%. Rectal injuries had the highest diversion rate (56%), followed by left-sided (41%) and right-sided (20%) locations (P < .0001). Those with gunshot wounds (GSW) underwent diversion more often than blast injuries (43% vs 31% respectively, P < .0008). Injury Severity Score ≥16 (41% vs 30%; P = .0018) and damage control surgery (DCS; 48.2% vs 31.4%; P < .0001) were associated with higher diversion rates. On multivariate analysis, significant predictors for colostomy creation were injury location: Rectal versus left colon (odds ratio [OR], 2.2), rectal versus right colon (OR, 7.5), left versus right colon (OR, 3.4), GSW (OR, 2.0), ISS ≥ 16 (OR, 1.7), and DCS (OR, 1.6). In this exploratory study of 320 combat-related colostomies, distal colon and rectal injuries continue to be diverted at higher rates independent of other comorbidities. Additional outcomes-directed research is needed to determine whether such operative management is beneficial in all patients. Published by Mosby, Inc.

This study evaluated a gender-specific, computer-mediated intervention program to prevent underage drinking among early adolescent girls. Study participants were adolescent girls and their mothers from New York, New Jersey, and Connecticut. Participants completed pretests online and were randomly divided between intervention and control arms. Intervention-arm girls and their mothers interacted with a computer program aimed to enhance mother-daughter relationships and to teach girls skills for managing conflict, resisting media influences, refusing alcohol and drugs, and correcting peer norms about underage drinking, smoking, and drug use. After intervention, all participants (control and intervention) completed posttest and follow-up measurements. Two months following program delivery and relative to control-arm participants, intervention-arm girls and mothers had improved their mother-daughter communication skills and their perceptions and applications of parental monitoring and rule-setting relative to girls' alcohol use. Also at follow-up, intervention-arm girls had improved their conflict management and alcohol use-refusal skills; reported healthier normative beliefs about underage drinking; demonstrated greater self-efficacy about their ability to avoid underage drinking; reported less alcohol consumption in the past 7 days, 30 days, and year; and expressed lower intentions to drink as adults. Study findings modestly support the viability of a mother-daughter, computer-mediated program to prevent underage drinking among adolescent girls. The data have implications for the further development of gender-specific approaches to combat increases in alcohol and other substance use among American girls.

Summary Objectives Military organizations are keen to address barriers to mental health care yet stigma and barriers to care remain little understood, especially potential cultural differences between Armed Forces. The aim of this study was to compare data collected by the US, UK, Australian, New Zealand and Canadian militaries using Hoge et al.'s perceived stigma and barriers to care measure (Combat duty in Iraq and Afghanistan, mental health problems and barriers to care. New Engl J Med 2004;351:13–22). Design Each member country identified data sources that had enquired about Hoge et al.'s perceived stigma and perceived barriers to care items in the re-deployment or immediate post-deployment period. Five relevant statements were included in the study. Setting US, UK Australian, New Zealand and Canadian Armed Forces. Results Concerns about stigma and barriers to care tended to be more prominent among personnel who met criteria for a mental health problem. The pattern of reported stigma and barriers to care was similar across the Armed Forces of all five nations. Conclusions Barriers to care continue to be a major issue for service personnel within Western military forces. Although there are policy, procedural and cultural differences between Armed Forces, the nations studied appear to share some similarities in terms of perceived stigma and barriers to psychological care. Further research to understand patterns of reporting and subgroup differences is required. PMID:20382906

The transformation of the modern battlefield with respect to weaponry, modes of transportation, enemy capabilities and location, as well as technological advances, has greatly altered the tactical approach to the mission. Combat casualty care must continually evolve in response to the differences in types of injury, the number and triage of casualties, timing of treatment, and location of care. These battlefield changes have been demonstrated on a large scale in the global war on terrorism, which includes the military operations in Afghanistan and Iraq. The medical response has kept pace with this 21st-century conflict. Even in the new environment of armed conflict and with the advent of new technologies, the principles of managing orthopaedic combat casualties remain clear: preservation of life and limb, skeletal stabilization, and aggressive wound débridement. For United States service members wounded in the current conflicts, Landstuhl Regional Medical Center is a crucial stop along the road to recovery.

Exposure to childhood adversity may explain why only a minority of combatants exposed to trauma develop psychological problems. To examine the association between self-reported childhood vulnerability and later health outcomes in a large randomly selected male military cohort. Data are derived from the first stage of a cohort study comparing Iraq veterans and non-deployed UK military personnel. We describe data collected by questionnaire from males in the regular UK armed forces (n=7937). Pre-enlistment vulnerability is associated with being single, of lower rank, having low educational attainment and serving in the Army. Pre-enlistment vulnerability is associated with a variety of negative health outcomes. Two main factors emerge as important predictors of ill health: a 'family relationships' factor reflecting the home environment and an 'externalising behaviour' factor reflecting behavioural disturbance. Pre-enlistment vulnerability is an important individual risk factor for ill health in military men. Awareness of such factors is important in understanding post-combat psychiatric disorder.

Background Among military personnel alcohol consumption and binge-drinking have increased but cigarette smoking has declined in the recent past. Although there is a strong association between smoking and PTSD the association between combat exposure and smoking is not clear. Methods This cross sectional study was carried out among representative samples of SLN Special Forces and regular forces deployed in combat areas. Both Special Forces and regular forces were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to end of combat operations were included in the study. Females were not included in the sample. The study assessed several mental health outcomes as well as alcohol use, smoking and cannabis use. Sample was classified according to smoking habits as never smokers, past smokers (those who had smoked in the past but not within the past year) and current smokers (those smoking at least one cigarette within the past 12 months). Results Sample consisted of 259 Special Forces and 412 regular navy personnel. Prevalence of current smoking was 17.9% (95% CI 14.9-20.8). Of the sample 58.4% had never smoked and 23.7% were past smokers. Prevalence of current smoking was significantly higher among Special Forces personnel compared to regular forces. (OR 1.90 (95% CI 1.20-3.02). Personnel aged ≥35 years had the lowest prevalence of smoking (14.0%). Commissioned officers had a lower prevalence (12.1%) than non commissioned officers or other ranks. After adjustment for demographic variables and service type there was significant association between smoking and combat experiences of seeing dead or wounded [OR 1.79 (95%CI 1.08-2.9)], handling dead bodies [OR 2.47(95%CI 1.6-3.81)], coming under small arms fire [OR 2.01(95%CI 1.28-3.15)] and coming under mortar, missile and artillery fire [OR 2.02(95%CI 1.29-3.17)]. There was significant association between the number of risk events and current smoking [OR 1.22 (95%CI1.11-1.35)]. Conclusions There was significant association between current smoking and combat experiences. Current smoking was strongly associated with current alcohol use. Prevalence of current smoking was less among military personnel than in the general population. Prevalence of smoking was significantly higher among Special Forces personnel. PMID:22776004
Molded Communication Earplugs in Military Aviation.
Lahtinen, Taija M M; Leino, Tuomo K
2015-09-01
Radio communication remains important for the delivery of safety-critical information in military aviation. Pilots are exposed to high noise levels. Noise attenuation provided by certain helmets is not sufficient, and resulting noise exposure can deteriorate operational effectiveness and flight safety. A need for hearing protection that enables efficient communication is obvious, especially for fighter and helicopter pilots. One possible solution for this issue is molded communication earplugs (m-CEP). Data about the advantages and disadvantages of m-CEPs are limited. To determine the usage rates, advantages, disadvantages and pilot opinions about m-CEPs, an anonymous survey study including 31 questions was conducted in fighter, fighter trainer, helicopter, and transport aircraft units of the Finnish Defense Forces. Of the pilots who responded, 136 (93%) had used or tried m-CEPs and 90 (62%) were currently using them. There are many benefits to m-CEPs: they seem to enhance experienced speech intelligibility, since 85% of the pilots who had experience about them reported improved speech intelligibility under difficult hearing conditions, and 93% would recommend them to other pilots. It seems m-CEPs provide equal benefits to pilots with and without current hearing problems. They were also considered better than previously used hearing protectors. Still, problems were common: 82% of the pilots reported m-CEP related drawbacks, of which technical problems and discomfort issues were the most prevalent. Most military pilots hold a positive opinion on m-CEPs and are willing to recommend their use. Technical problems and discomfort issues are, however, relatively common.

To estimate the prevalence and to analyze the factors associated with self-reported hearing handicap by construction workers in the state of Mato Grosso, Brazil. A cross-sectional study was conducted with 866 construction and heavy construction workers. Participants responded to an epidemiological survey subdivided in: identification data, sociodemographic data; lifestyle; work environment characteristics; occupational exposure factors; hearing protection measures; and hearing handicap inventory to quantify the psychosocial consequences of work-related hearing loss. The prevalence of hearing impairment among workers in the construction sector was 14.43% (n = 125). There were 311 emotional and social complaints related to hearing problems. Hearing handicap was associated with: 60 or over age group (PR = 1.94, 95%CI 1.01 - 3.71); alcohol consumption (PR = 1.94, 95%CI 1.38 - 2.73); direct exposure to noise (PR = 1.75; 95%CI 1.03 - 2.97); exposure to dust (PR = 1.59, 95%CI 1.13 - 2.24); non-use of earplugs (PR = 1.39, 95%CI 1.00 - 1.93); and non-use of neck flap cap (PR = 1.52, 95%CI 1.09 - 2.13). We observed a high prevalence of hearing impairment among workers in the construction sector associated with: individuals aged 60 years or older; alcoholism; exposure to noise and dust; non-use of earplugs; and non-use of neck flap cap. Therefore, it is necessary to implement policies aimed at preserving the hearing health of construction and heavy construction workers.

The high prevalence of metabolic syndrome (MetS) has highlighted the need for effective dietary interventions to combat this growing problem. To assess the impact of a Mediterranean-style low-glycemic-load diet (control arm, n = 44) or the same diet plus a medical food containing phytosterols, soy protein, and extracts from hops and acacia (intervention arm, n = 45) on cardiometabolic risk variables in women with MetS. In this 12-week, 2-arm randomized trial, baseline, week 8 and 12, fasting blood samples were drawn to measure plasma lipids, apolipoproteins, and homocysteine. Dietary records were also collected and analyzed. There were decreases in fat and sugar intake (P < .001 for both) and increases in docosahexaenoic acid and eicosapentaenoic acid intake (P < .001 for both) over time, consistent with the prescribed diet. Regarding MetS variables, there were decreases in waist circumference, systolic and diastolic blood pressure, and plasma triglycerides in all subjects (P < .001 for all) with no differences between arms. Plasma low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, apolipoprotein (apo) B, and apo B/apo A1 were reduced over time but to a greater extent in the intervention arm (P < .05 for all), indicating the medical food had a greater effect in altering lipoprotein metabolism. Further, medical food intake was associated with reduced plasma homocysteine (P < .01) compared to the control arm. A Mediterranean-style low-glycemic-load diet effectively reduces the variables of MetS. Addition of the medical food results in a less atherogenic lipoprotein profile and lower plasma homocysteine.

Sex trafficking and sexual exploitation has been widely reported, especially in conflict-affected settings, which appear to increase women's and children's vulnerabilities to these extreme abuses. We conducted a systematic search of ten databases and extensive grey literature to gather evidence of sex trafficking and sexual exploitation in conflict-affected settings. International definitions of "sexual exploitation" and "sex trafficking" set the indicator parameters. We focused on sexual exploitation in forms of early or forced marriage, forced combatant sexual exploitation and sexual slavery. We extracted prevalence measures, health outcomes and sexual exploitation terminology definitions. The review adhered to PRISMA guidelines and includes quality appraisal. The search identified 29 eligible papers with evidence of sex trafficking and sexual exploitation in armed conflict settings in twelve countries in Africa, Asia, and the Middle East. The evidence was limited and not generalizable, due to few prevalence estimates and inconsistent definitions of "sexual exploitation". The prevalence estimates available indicate that females were more likely than males to be victims of sexual exploitation in conflict settings. In some settings, as many as one in four forced marriages took place before the girls reached 18 years old. Findings suggest that the vast majority of former female combatants were sexually exploited during the conflict. These studies provided various indicators of sexual exploitation compatible to the United Nation's definition of sex trafficking, but only 2 studies identified the exploitation as trafficking. None of the studies solely aimed to measure the prevalence of sex trafficking or sexual exploitation. Similar descriptions of types of sexual exploitation and trafficking were found, but the inconsistent terminology or measurements inhibited a meta-analysis. Findings indicate there are various forms of human trafficking and sexual exploitation in conflict-affected settings, primarily occurring as early or forced marriage, forced combatant sexual exploitation, and sexual slavery. The studies highlight the extraordinary vulnerability of women and girls to these extreme abuses. Simultaneously, this review suggests the need to clarify terminology around sex trafficking in conflict to foster a more cohesive future evidence-base, and in particular, robust prevalence figures from conflict-affected and displaced populations.

In this report, a new star-like copolymer β-CD- g-(PNIPAAm- b-POEGA) x , consisting of a β-CD core, grafted with temperature-responsive poly( N-isopropylacrylamide) (PNIPAAm) and biocompatible poly(oligo(ethylene glycol) acrylate) (POEGA) in a block copolymer of the arms, was used to deliver chemotherapeutics to drug resistant cancer cells and tumors. The first step of the self-assembly process involves the encapsulation of chemotherapeutics through host-guest inclusion complexation between the β-cyclodextrin cavity and the anticancer drug. Next, the chain interaction of the PNIPAAm segment at elevated temperature drives the drug-loaded β-CD- g-(PNIPAAm- b-POEGA) x /PTX inclusion complex to hierarchically self-assemble into nanosized supramolecular assemblies at 37 °C, whereas the presence of poly(ethylene glycol) (PEG) chains in the distal end of the star-like copolymer arms impart enhanced stability to the self-assembled structure. More interestingly, this supramolecular host-guest nanocomplex promoted the enhanced cellular uptake of chemotherapeutics in MDR-1 up-regulated drug resistant cancer cells and exhibited high therapeutic efficacy for suppressing drug resistant tumor growth in an in vivo mouse model, due to the increased stability, improvement in aqueous solubility, enhanced cellular uptake, and partial membrane pump impairment by taking the advantage of PEGylation and supramolecular complex between this star-like copolymer and chemotherapeutics. This work signifies that temperature-sensitive PEGylated supramolecular nanocarriers with good biocompatibility are effective in combating MDR-1 mediated drug resistance in both in vitro and in vivo models, which is of significant importance for the advanced drug delivery platform designed to combat drug resistant cancer.
Arms races and the evolution of big fierce societies.

The causes of biological gigantism have received much attention, but only for individual organisms. What selection pressures might favour the evolution of gigantic societies? Here we consider the largest single-queen insect societies, those of the Old World army ant Dorylus, single colonies of which can have 20 million workers. We propose that colony gigantism in Dorylus arises as a result of an arms race and test this prediction by developing a size-structured mathematical model. We use this model for exploring and potentially explaining differences in colony size, colony aggression and colony propagation strategies in populations of New World army ants Eciton and Old World army ants Dorylus. The model shows that, by determining evolutionarily stable strategies (ESSs), differences in the trophic levels at which these army ants live feed forwards into differences in their densities and collision rates and, hence, into different strategies of growth, aggression and propagation. The model predicts large colony size and the occurrence of battles and a colony-propagation strategy involving highly asymmetrical divisions in Dorylus and that Eciton colonies should be smaller, non-combative and exhibit equitable binary fission. These ESSs are in excellent agreement with field observations and demonstrate that gargantuan societies can arise through arms races.

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.

This paper reviews the most common health hazards occurring among personnel of peacekeeping and stabilization missions functioning within armed conflicts in the contemporary world. Military operations have been executed in diverse climatic and sanitary conditions, which are frequently unfamiliar for their participants. Some of them, e.g. the UN peacekeeping missions in the Middle East (Lebanon, the Golan Heights), have been carried out in a relatively stable geopolitical environment; whereas, stabilization missions in Iraq and Afghanistan, which are actually combat activities, undoubtedly fall into the group of the most perilous military operations in the world. Hot or cold climate, poor sanitary and hygienic conditions along with warfare facilitate the occurrence of numerous diseases and body injuries not only among the local people but also among peacekeepers, who represent the population of immigrants. Health hazards which pose major epidemiological threats in combat zones are arthropod-borne, food and water-borne, respiratory tract diseases, sexually transmitted diseases, enzootic diseases, battle injuries, and non- -battle injuries, e.g. traffic accidents. Another considerable health problem are psychiatric disorders, which can either appear directly after the occurrence of a traumatic event in a combat zone or indirectly, after some time had elapsed. In addition to the health hazards listed above, environmental factors such as changeable weather conditions and local fauna may also be life threatening.

The battle against noise in industry
NASA Astrophysics Data System (ADS)
Iudin, E. Ia.
The physiological effects of noise in manufacturing plants and other industrial facilities are discussed, and several common noise abatement methods are described. Consideration is given to the acoustic properties of three types of noise which are present in industrial plants: aerohydrodynamic noise; mechanical noise; and electromagnetic noise. Among the specific noise abatement techniques discussed are: sound isolation by means of noise-absorbant screens; insulation or noise-emitting media; and acoustic interference. The use of earplugs and external ear protectors for protection of individual workers in noisy work environments is also considered.

Objective: This study evaluated a gender-specific, computer-mediated intervention program to prevent underage drinking among early adolescent girls. Method: Study participants were adolescent girls and their mothers from New York, New Jersey, and Connecticut. Participants completed pretests online and were randomly divided between intervention and control arms. Intervention-arm girls and their mothers interacted with a computer program aimed to enhance mother-daughter relationships and to teach girls skills for managing conflict, resisting media influences, refusing alcohol and drugs, and correcting peer norms about underage drinking, smoking, and drug use. After intervention, all participants (control and intervention) completed posttest and follow-up measurements. Results: Two months following program delivery and relative to control-arm participants, intervention-arm girls and mothers had improved their mother-daughter communication skills and their perceptions and applications of parental monitoring and rule-setting relative to girls' alcohol use. Also at follow-up, intervention-arm girls had improved their conflict management and alcohol use-refusal skills; reported healthier normative beliefs about underage drinking; demonstrated greater self-efficacy about their ability to avoid underage drinking; reported less alcohol consumption in the past 7 days, 30 days, and year; and expressed lower intentions to drink as adults. Conclusions: Study findings modestly support the viability of a mother-daughter, computer-mediated program to prevent underage drinking among adolescent girls. The data have implications for the further development of gender-specific approaches to combat increases in alcohol and other substance use among American girls. PMID:19118394

To increase aircrewmen's chances for safe rescue in combat zones, the armed forces are investigating advanced escape and rescue concepts that will provide independent flight after ejection and thus reduce the risk of capture. One of the candidate concepts is discussed; namely, a stowable autogyro that serves as the crewman's seat during normal operations and automatically converts to a flight vehicle after ejection. Discussed are (1) the mechanism subsystems that the concept embodies to meet the weight and cockpit-packaging constraints and (2) tests that demonstrated the technical feasibility of the stowage, deployment, and flight operation of the rotor lift system.

Power capacity from earcanal dynamic motion

In-ear devices, such as a hearing aids, electronic earplugs, and wearables, need electrical power to operate. Batteries are the current solution, but unfortunately they also create other problems. For example, several hundred million users, mostly elderly, must change their hearing aid batteries on a weekly basis, which represents not only significant financial costs but a negative environmental impact. A promising alternative involves harvesting energy by converting the dynamic jaw movements into electrical energy via the earcanal. The extent that jaw movements distort the earcanal is still unknown, making it difficult to design the appropriate energy harvesting system for the earplug. Moreover, the finite element methods are barely capable to model the behavior of the earcanal distortion because of the complexity of mechanisms that deform the earcanal. However, this paper presents an alternative method, based on analytical considerations, to understand in-ear mechanical quasi-static deformations using earcanal point clouds. This model quantifies the bending and compressive movements of the earcanal. It can therefore be used to select an appropriate deformation mode for harvesting energy from the earcanal's dynamic motion. The value of this approach was illustrated by calculating the obtainable mechanical energy from 12 human subjects. On average, the bending energy in a human earcanal was found to be three times greater than the radial compression energy. This key finding will need to be considered in the design of future in-ear energy harvesting devices. Such an energy harvesting device has the potential to revolutionize the market for in-ear wearable devices and hearing aids by complementing or replacing battery technology.

This study aimed to analyze and compare four different types of earplugs, divided into premolded plugs and foam plug models, in relation to the level of attenuation, comfort, and the size of the external acoustic meatus (EAM) in an attempt to identify how these variables influence the choice of specific hearing protection devices (HPDs). A cross-sectional observational study was performed in a sample of 49 participants, oriented toward the ideal placement of four HPDs, two premolded and two foam plugs (3M™). The procedures included otoscopy, EAM diameter measurement using an otometer, EAM volume measurement via an acoustic impedance test, and the obtainment of the bilateral personal attenuation rating (PAR) for each HPD using the E-A-Rfit™ Validation System (3M™). The Bipolar Comfort Rating Scale (BCRS) instrument was applied twice for each individual: once after the evaluations with the premolded HPDs and again after the evaluations with the foam plug HPDs. Then, each participant was asked which was his/her favorite protector. The volume of the EAM was not directly related to the diameter of the EAM. The attenuation did not interfere with the HPD preference, and the PAR of the foam plug was significantly higher regardless of the preferred HPD. Regarding the BCRS, the variables "Placement," "Complexity," and "Occlusion Effect" had higher scores for premolded HPDs and had a direct relationship with the type of preferred HPD. Attention to the use of HPDs should be personalized, taking into account the needs of each individual, considering not only the attenuation, but also the user's reported well-being.

Adults in intensive care units (ICUs) often suffer from a lack of sleep or frequent sleep disruptions. Non-pharmacological interventions can improve the duration and quality of sleep and decrease the risk of sleep disturbance, delirium, post-traumatic stress disorder (PTSD), and the length of stay in the ICU. However, there is no clear evidence of the effectiveness and harms of different non-pharmacological interventions for sleep promotion in adults admitted to the ICU. To assess the efficacy of non-pharmacological interventions for sleep promotion in critically ill adults in the ICU.To establish whether non-pharmacological interventions are safe and clinically effective in improving sleep quality and reducing length of ICU stay in critically ill adults.To establish whether non-pharmacological interventions are cost effective. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2014, Issue 6), MEDLINE (OVID, 1950 to June 2014), EMBASE (1966 to June 2014), CINAHL (Cumulative Index to Nursing and Allied Health Literature, 1982 to June 2014), Institute for Scientific Information (ISI) Web of Science (1956 to June 2014), CAM on PubMed (1966 to June 2014), Alt HealthWatch (1997 to June 2014), PsycINFO (1967 to June 2014), the China Biological Medicine Database (CBM-disc, 1979 to June 2014), and China National Knowledge Infrastructure (CNKI Database, 1999 to June 2014). We also searched the following repositories and registries to June 2014: ProQuest Dissertations & Theses Global, the US National Institutes of Health Ongoing Trials Register (www.clinicaltrials.gov), the metaRegister of Controlled Trials (ISRCTN Register) (www.controlled-trials.com), the Chinese Clinical Trial Registry (www.chictr.org.cn), the Clinical Trials Registry-India (www.ctri.nic.in), the Grey Literature Report from the New York Academy of Medicine Library (www.greylit.org), OpenGrey (www.opengrey.eu), and the World Health Organization International Clinical Trials Registry platform (www.who.int/trialsearch). We handsearched critical care journals and reference lists and contacted relevant experts to identify relevant unpublished data. We included all randomized controlled trials (RCT) and quasi-RCTs that evaluated the effects of non-pharmacological interventions for sleep promotion in critically ill adults (aged 18 years and older) during admission to critical care units or ICUs. Two authors independently screened the search results and assessed the risk of bias in selected trials. One author extracted the data and a second checked the data for accuracy and completeness. Where possible, we combined results in meta-analyses using mean differences and standardized mean differences for continuous outcomes and risk ratios for dichotomous outcomes. We used post-test scores in this review. We included 30 trials, with a total of 1569 participants, in this review. We included trials of ventilator mode or type, earplugs or eye masks or both, massage, relaxation interventions, foot baths, music interventions, nursing interventions, valerian acupressure, aromatherapy, and sound masking. Outcomes included objective sleep outcomes, subjective sleep quality and quantity, risk of delirium, participant satisfaction, length of ICU stay, and adverse events. Clinical heterogeneity (e.g., participant population, outcomes measured) and research design limited quantitative synthesis, and only a small number of studies were available for most interventions. The quality of the evidence for an effect of non-pharmacological interventions on any of the outcomes examined was generally low or very low. Only three trials, all of earplugs or eye masks or both, provided data suitable for two separate meta-analyses. These meta-analyses, each of two studies, showed a lower incidence of delirium during ICU stay (risk ratio 0.55, 95% confidence interval (CI) 0.38 to 0.80, P value = 0.002, two studies, 177 participants) and a positive effect of earplugs or eye masks or both on total sleep time (mean difference 2.19 hours, 95% CI 0.41 to 3.96, P value = 0.02, two studies, 116 participants); we rated the quality of the evidence for both of these results as low.There was also some low quality evidence that music (350 participants; four studies) may improve subjective sleep quality and quantity, but we could not pool the data. Similarly, there was some evidence that relaxation techniques, foot massage, acupressure, nursing or social intervention, and sound masking can provide small improvements in various subjective measures of sleep quality and quantity, but the quality of the evidence was low. The effects of non-pharmacological interventions on objective sleep outcomes were inconsistent across 16 studies (we rated the quality of the evidence as very low): the majority of studies relating to the use of earplugs and eye masks found no benefit; results from six trials of ventilator modes suggested that certain ventilator settings might offer benefits over others, although the results of the individual trials did not always agree with each other. Only one study measured length of stay in the ICU and found no significant effect of earplugs plus eye masks. No studies examined the effect of any non-pharmacological intervention on mortality, risk of post-traumatic stress disorder, or cost-effectiveness; the included studies did not clearly report adverse effects, although there was very low quality evidence that ventilator mode influenced the incidence of central apnoeas and patient-ventilator asynchronies. The quality of existing evidence relating to the use of non-pharmacological interventions for promoting sleep in adults in the ICU was low or very low. We found some evidence that the use of earplugs or eye masks or both may have beneficial effects on sleep and the incidence of delirium in this population, although the quality of the evidence was low. Further high-quality research is needed to strengthen the evidence base.

Now in connection with common situation in Russian Federation the problem of reinforcements of army and fleet by healthy personnel, scare of a call-up quota and its poor quality are the main problems of the Armed Forces at the state level. The uniform complex program of medico-social maintenance of the citizens during preparation for military service is necessary. The modern situation is difficult due to many infectious diseases, so the role and the place of military-medical service grows. In last years structure of quota, served by the military doctors, and number of other parameters have greatly changed, that require revision of some priorities. A problem of reinforcements of the Armed Forces by medical service officers remains actual, for decision of which a full-bodied admission on military medical faculty is required, as well as admission of the officers under contract and calling-up of reserve officers. In article the main lessons, received by the medical service during combat actions in Republic of Chechnya are also formulated.

This paper argues for the continued significance of the text as a source and focus in critical geopolitical inquiry. It establishes the utility of the military memoir in explorations of popular contemporary geopolitical imaginaries, and considers the memoir as a vector of militarism. The paper examines the memoirs written by military personnel about service in Afghanistan with the British armed forces, specifically about deployments to Helmand province between 2006 and 2012. The paper explores how Afghanistan is scripted through these texts, focussing on the explanations for deployment articulated by their authors, on the representations they contain and promote about other combatants and about civilian non-combatants, and the constitution and expression of danger in the spaces and places of military action which these texts construct and convey. The paper then turns to consider how a reading of the military memoir with reference to the genre of testimonio might extend and inform our understanding and use of these texts as a source for exploring popular geopolitics and militarism.

Abstract Previous studies indicate positive home advantage in judo; however, the factors that influence home advantage have yet to be fully explored. This study investigated the potential differences in technical-tactical variables between home and visiting athletes. A total of 1411 video recorded matches were analyzed (123 home, 1288 away) from 36 international judo competitions contested in 2011-12. The matches were analyzed by the following criteria: combat phases (approach, gripping, attack, defense, groundwork and pause), penalties (by the athlete or the opponent) and the types of attacks (with or without a score). Elite judo athletes competing in their home country attacked more frequently using trunk/leg couple techniques (p < 0.011) and scored more frequently with arm/leg couple techniques (p < 0.001), while visiting judo athletes received fewer scores from penalties (p < 0.001) and engaged in more frequent pauses during competition (p < 0.01). The results of this study provide an outline of technical-tactical differences that may contribute to home advantage in judo. PMID:28713473
Does Combat Hearing Preservation Equipment Affect Balance?

(1) To investigate whether the occlusion effect and hearing attenuation produced by 3M Combat Arms Ear Plugs (CAEP) affects balance when compared to no hearing protection and (2) to investigate whether the occlusion effect and noise-canceling capabilities of the Nacre QuietPro system affects balance when compared to no hearing protection. This prospective study collected pilot data for investigation of mechanisms of balance. 20 subjects with normal hearing and no vestibular dysfunction were tested with blackened goggles in three conditions-no hearing protection, CAEP, and with the Nacre QuietPro. A static posturogrpahy forceplate was used to measure center of gravity angular acceleration for a period of 20 seconds. The order of the conditions tested was randomized for each individual. Mean angular acceleration and standard deviation (degrees/second) of the three conditions were: (1) no hearing protection (control), 0.65 + 0.19, (2) CAEP, 0.69 + 0.23, and (3) QuietPro, 0.70 + 0.20 (one-way analysis of variance [ANOVA], df = 2, F = 0.38, p = 0.706). The components of an intact balance system include a variety of neural inputs, to include vesitbuloocular, vestibulospinal, and labyrinthine afferents. Both the CAEP and Nacre QuietPro are hearing preservation devices utilized during Operation Iraqi Freedom and Operation Enduring Freedom in Afghanistan. Our pilot data show no decrement in balance with utilization of these combat hearing preservation devices. Reprint & Copyright © 2017 Association of Military Surgeons of the U.S.
Optical bullet-tracking algorithms for weapon localization in urban environments
DOE Office of Scientific and Technical Information (OSTI.GOV)
Roberts, R S; Breitfeller, E F
2006-03-31
Localization of the sources of small-arms fire, mortars, and rocket propelled grenades is an important problem in urban combat. Weapons of this type produce characteristic signatures, such as muzzle flashes, that are visible in the infrared. Indeed, several systems have been developed that exploit the infrared signature of muzzle flash to locate the positions of shooters. However, systems based on muzzle flash alone can have difficulty localizing weapons if the muzzle flash is obscured or suppressed. Moreover, optical clutter can be problematic to systems that rely on muzzle flash alone. Lawrence Livermore National Laboratory (LLNL) has developed a projectile trackingmore » system that detects and localizes sources of small-arms fire, mortars and similar weapons using the thermal signature of the projectile rather than a muzzle flash. The thermal signature of a projectile, caused by friction as the projectile travels along its trajectory, cannot be concealed and is easily discriminated from optical clutter. The LLNL system was recently demonstrated at the MOUT facility of the Aberdeen Test Center [1]. In the live-fire demonstration, shooters armed with a variety of small-arms, including M-16s, AK-47s, handguns, mortars and rockets, were arranged at several positions in around the facility. Experiments ranged from a single-weapon firing a single-shot to simultaneous fire of all weapons on full automatic. The LLNL projectile tracking system was demonstrated to localize multiple shooters at ranges up to 400m, far greater than previous demonstrations. Furthermore, the system was shown to be immune to optical clutter that is typical in urban combat. This paper describes the image processing and localization algorithms designed to exploit the thermal signature of projectiles for shooter localization. The paper begins with a description of the image processing that extracts projectile information from a sequence of infrared images. Key to the processing is an adaptive spatio-temporal filter developed to suppress scene clutter. The filtered image sequence is further processed to produce a set of parameterized regions, which are classified using several discriminate functions. Regions that are classified as projectiles are passed to a data association algorithm that matches features from these regions with existing tracks, or initializes new tracks as needed. A Kalman filter is used to smooth and extrapolate existing tracks. Shooter locations are determined by solving a combinatorial least-squares solution for all bullet tracks. It also provides an error ellipse for each shooter, quantifying the uncertainty of shooter location. The paper concludes with examples from the live-fire exercise at the Aberdeen Test Center.« less

Neurological injuries remain a major concern following coronary artery bypass grafting (CABG) that offsets survival benefit of CABG over percutaneous coronary interventions. Among numerous efforts to combat this issue is the development of off-pump CABG (OPCABG) that obviates the need for extracorporeal circulation and is associated with improved neurological outcomes. The objective of this study is to examine whether the neuroprotective effect of OPCABG can be further pronounced by the use of two state-of-the-art operating techniques. In this randomised, controlled, investigator and patient blinded single-centre superiority trial with three parallel arms, a total of 360 patients will be recruited. They will be allocated in a 1:1:1 ratio to two treatment arms and one control arm. Treatment arms undergoing either aortic no-touch OPCABG or OPCABG with partial clamp applying carbon dioxide surgical field flooding will be compared against control arm undergoing OPCABG with partial clamp. The primary endpoint will be the appearance of new lesions on control brain MRI 3 days after surgery. Secondary endpoints will include the prevalence of new focal neurological deficits in the first 7 days after surgery, the occurrence of postoperative cognitive dysfunction at either 1 week or 3 months after surgery and the incidence of delirium in the first 7 days after surgery. Data will be analysed on intention-to-treat principles and a per protocol basis. Ethical approval has been granted for this study. Results will be disseminated through peer-reviewed media.

Objective Soldiers’ mental health is adversely affected by the death and injury of other unit members, but it is not known if risk of suicide attempt is influenced by previous suicide attempts in one’s unit. Method Using administrative data from the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS), we identified person-month records for all active duty Regular Army enlisted soldiers who attempted suicide from 2004–2009 (n=9,650) and an equal-probability sample of control person-months (n=153,528). Logistic regression analyses examined the number of past-year suicide attempts in one’s unit as a predictor of subsequent suicide attempt, controlling for socio-demographics, service-related characteristics, prior mental health diagnosis, and other unit variables, including suicide-, combat-, and accident-related unit deaths. We also examined whether the influence of previous unit suicide attempts varied by military occupational specialty (MOS) and unit size. Results In adjusted models, soldiers were more likely to attempt suicide if one or more suicide attempts occurred in their unit during the past year (OR=1.4–2.3; p<0.001), with odds increasing as the number of unit attempts increased. The odds of suicide attempt among soldiers in a unit with five or more past-year attempts was more than twice that of soldiers in a unit with no previous attempts (OR=2.3; 95% CI=2.1–2.6). The association of previous unit suicide attempts with subsequent risk was significant whether soldiers had a combat arms MOS or other MOS (OR=1.4–2.3; p<0.001). It was also significant regardless of unit size, with the highest risk for those in smaller units (1–40 soldiers) (OR=2.1–5.9; p<0.001). The population-attributable risk proportion for one or more unit suicide attempts in the past year indicated that if this risk could be reduced to no unit attempts, 18.2% of attempts would not occur. Conclusions Soldiers’ risk of suicide attempt increased as the number of past-year suicide attempts within their unit increased. This was true for both combat arms and other MOSs, and for units of any size, but particularly for smaller units. Units with a history of suicide attempts may be important targets for preventive interventions. PMID:28746705
The neurophysiological and evolutionary considerations of close combat: A modular approach.
Dervenis, Kostas; Tsialogiannis, Evangelos
2017-01-01
Close Combat may be identified as a physical confrontation involving armed or unarmed fighting, lethal and/or non-lethal methods, or even simply escape from and/or de-escalation of the confrontation. Our model hypothesizes that distinct areas of the brain are utilized for specific levels of violence, based on evolutionary criteria, and that these levels of violence bring into effect distinct physiological criteria and kinesiology. This model is outlined similar to Paul D. MacLean's triune brain theory, but incorporates distinct processes inherent to the autonomic nervous system (i.e. a "quadrune brain"), and correlates the observed level of violence to a particular response to a specific neural complex associated with very specific reactive kinesiology in the body. Our hypothesis is that the reverse also holds true: specific movements, scenarios and breathing will "activate" corresponding neural centres that in turn correlate to a respective level of violence. Moreover, socio-historic records bear out the premise that specific behavioural violations of social protocols act as "triggers" for assaultive and lethal force involving weapons, and it is very likely that these triggers (and the concomitant decision to engage in assault or lethal force) are processed through neural centres in what McLean has described as his "limbic system." A modular system of close combat is being researched and developed in accord with the above, readily adaptable to the level of violence professional peacekeepers and law enforcement officers may encounter in the course of their duties, but also directly relevant to the self-protection needs of civilians and youth. Distinct modular training regimes have been identified and developed for situations involving escape from a threat, submission of an adversary, and assaultive/lethal force, with the hope of strengthening neural bridges between the four neural complexes postulated in our model, and therefore via these bridges limiting adverse reactions to the psyche from combat stress.
Update: Exertional rhabdomyolysis, active component, U.S. Armed Forces, 2012-2016.
2017-03-01
Among active component service members in 2016, there were 525 incident diagnoses of rhabdomyolysis likely due to physical exertion and/or heat stress ("exertional rhabdomyolysis"). The crude incidence rate in 2016 was 40.7 cases per 100,000 person-years. Annual rates of incident diagnoses of exertional rhabdomyolysis increased 46.2% between 2013 and 2016, with the greatest percentage change occurring between 2014 and 2015. In 2016, relative to their respective counterparts, the highest incidence rates of exertional rhabdomyolysis affected service members who were male; younger than 20 years of age; and black, non-Hispanic. During the surveillance period, annual incidence rates were highest among service members of the Marine Corps, intermediate among those in the Army, and lowest among those in the Air Force and Navy. Most cases of exertional rhabdomyolysis were diagnosed at installations that support basic combat/recruit training or major ground combat units of the Army or the Marine Corps. Medical care providers should consider exertional rhabdomyolysis in the differential diagnosis when service members (particularly recruits) present with muscular pain or swelling, limited range of motion, or the excretion of dark urine (possibly due to myoglobinuria) after strenuous physical activity, particularly in hot, humid weather.
Greasy tactics in the plant-pathogen molecular arms race.
Boyle, Patrick C; Martin, Gregory B
2015-03-01
The modification of proteins by the attachment of fatty acids is a targeting tactic involved in mechanisms of both plant immunity and bacterial pathogenesis. The plant plasma membrane (PM) is a key battleground in the war against disease-causing microbes. This membrane is armed with an array of sensor proteins that function as a surveillance system to detect invading pathogens. Several of these sensor proteins are directed to the plasma membrane through the covalent addition of fatty acids, a process termed fatty acylation. Phytopathogens secrete effector proteins into the plant cell to subvert these surveillance mechanisms, rendering the host susceptible to infection. The targeting of effectors to specific locales within plant cells, particularly the internal face of the host PM, is critical for their virulence function. Several bacterial effectors hijack the host fatty acylation machinery to be modified and directed to this contested locale. To find and fight these fatty acylated effectors the plant leverages lipid-modified intracellular sensors. This review provides examples featuring how fatty acylation is a battle tactic used by both combatants in the molecular arms race between plants and pathogens. Also highlighted is the exploitation of a specific form of host-mediated fatty acid modification, which appears to be exclusively employed by phytopathogenic effector proteins. © The Author 2015.

Buried treasure: evolutionary perspectives on microbial iron piracy
Barber, Matthew F.; Elde, Nels C.
2015-01-01
Host-pathogen interactions provide valuable systems for the study of evolutionary genetics and natural selection. The sequestration of essential iron has emerged as a critical innate defense system termed nutritional immunity, leading pathogens to evolve mechanisms of `iron piracy' to scavenge this metal from host proteins. This battle for iron carries numerous consequences not only for host-pathogen evolution, but also microbial community interactions. Here we highlight recent and potential future areas of investigation on the evolutionary implications of microbial iron piracy in relation to molecular arms races, host range, competition, and virulence. Applying evolutionary genetic approaches to the study of microbial iron acquisition could also provide new inroads for understanding and combating infectious disease. PMID:26431675
Pseudofolliculitis barbae: review and update on new treatment modalities.
Garcia-Zuazaga, Jorge
2003-07-01
Pseudofolliculits barbae, PFB, is a common cutaneous disease encountered frequently in medical practice. PFB represents a chronic inflammatory condition of the hair follicle caused by ingrown hairs producing an inflammatory foreign body reaction. The pathogenesis of PFB is multifactorial. Factors such as hair type and direction of hair growth play a role in the initial inflammatory reaction. In the armed forces, PFB represents a real challenge for both the physician and the patient. The combat environment, with the recent threat of biological and chemical weapons, requires the servicemen to be clean-shaven for appropriate gas mask fitting around the face. This article will review the etiology, pathogenesis, classification, and newer treatment modalities in the management of PFB.

Depending on the exposure to traumatic stressors and combat, 20% to 50% of ex-combatants present with trauma-related disorders, and more than half of the members of armed groups have a proclivity to violence. Therefore, psychotherapeutic assistance should address both, trauma-related suffering and the lowered threshold for aggressive behaviour. Supporting the demobilization process of ex-combatants in the eastern DR-Congo, we implemented a version of Narrative Exposure Therapy adapted for Forensic Offender Rehabilitation (FORNET). In two successive dissemination stages (DS), local counsellors conducted FORNET. In DS1, they were trained by clinical experts, and in DS2, the by then experienced counsellors trained and supervised a second group of local counsellors (DS2). The training consisted of a 3-week workshop covering theoretical concepts and practical therapeutic skills. In DS1 and DS2, a total of 98 demobilizing combatants received an intervention; treatment-as-usual served as the control condition. Posttraumatic stress disorder, appetitive aggression, depression severity and drug dependence were assessed prior to the intervention and 6 and 12 months later; additionally, we assessed reintegration success. Six months post-intervention, FORNET significantly reduced Posttraumatic stress disorder symptoms but had less effect on the trait of appetitive aggression; moreover, beneficial effects were found for depression severity and drug dependence as well as for reintegration indices. Treatment gains were retained at 12 months. Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET and support the demobilization process in ongoing conflicts. The study suggests that it is possible to pass down psychotherapeutic techniques over generations of counsellors. © 2015 The Authors.

Muscle tissue oxygenation (SmO 2 ) can track central blood volume loss associated with hemorrhage. Traditional peripheral measurement sites (e.g., forearm) may not be practical due to excessive movement or injury (e.g., amputation). The aim of this study was to evaluate the efficacy of three novel anatomical sites for the assessment of SmO 2 under progressive central hypovolemia. 10 male volunteers were exposed to stepwise prone lower body negative pressure to decrease central blood volume, while SmO 2 was assessed at four sites-the traditional site of the flexor carpi ulnaris (ARM), and three novel sites not previously investigated during lower body negative pressure, the deltoid, latissimus dorsi, and trapezius. SmO 2 at the novel sites was compared to the ARM sensor and to stroke volume responses. A reduction in SmO 2 was detected by the ARM sensor at the first level of lower body negative pressure (-15 mmHg; P = 0.007), and at -30 (the deltoid), -45 (latissimus dorsi), and -60 mmHg lower body negative pressure (trapezius) at the novel sites (P ≤ 0.04). SmO 2 responses at all novel sites were correlated with responses at the ARM (R ≥ 0.89), and tracked the reduction in stroke volume (R ≥ 0.87); the latissimus dorsi site exhibited the strongest linear correlations (R ≥ 0.96). Of the novel sensor sites, the latissimus dorsi exhibited the strongest linear associations with SmO 2 at the ARM, and with reductions in central blood volume. These findings have important implications for detection of hemorrhage in austere environments (e.g., combat) when use of a peripheral sensor may not be ideal, and may facilitate incorporation of these sensors into uniforms. © 2016 by the Society for Experimental Biology and Medicine.

Infants in the neonatal intensive care unit (NICU) are subjected to stress, including sound of high intensity. The sound environment in the NICU is louder than most home or office environments and contains disturbing noises of short duration and at irregular intervals. There are competing auditory signals that frequently challenge preterm infants, staff and parents. The sound levels in NICUs often exceed the maximum acceptable level of 45 decibels (dB), recommended by the American Academy of Pediatrics. Hearing impairment is diagnosed in 2% to 10% of preterm infants versus 0.1% of the general paediatric population. Noise may cause apnoea, hypoxaemia, alternation in oxygen saturation, and increased oxygen consumption secondary to elevated heart and respiratory rates and may, therefore, decrease the amount of calories available for growth. Elevated levels of speech are needed to overcome the noisy environment in the NICU, thereby increasing the negative impacts on staff, newborns, and their families. High noise levels are associated with an increased rate of errors and accidents, leading to decreased performance among staff. The aim of interventions included in this review is to reduce sound levels to 45 dB or less. This can be achieved by lowering the sound levels in an entire unit, treating the infant in a section of a NICU, in a 'private' room, or in incubators in which the sound levels are controlled, or reducing the sound levels that reaches the individual infant by using earmuffs or earplugs. By lowering the sound levels that reach the neonate, the resulting stress on the cardiovascular, respiratory, neurological, and endocrine systems can be diminished, thereby promoting growth and reducing adverse neonatal outcomes. Primary objectiveTo determine the effects of sound reduction on growth and long-term neurodevelopmental outcomes of neonates. Secondary objectives1. To evaluate the effects of sound reduction on short-term medical outcomes (bronchopulmonary dysplasia, intraventricular haemorrhage, periventricular leukomalacia, retinopathy of prematurity).2. To evaluate the effects of sound reduction on sleep patterns at three months of age.3. To evaluate the effects of sound reduction on staff performance.4. To evaluate the effects of sound reduction in the neonatal intensive care unit (NICU) on parents' satisfaction with the care. We searched the Cochrane Central Register of Controlled Trials (The Cochrane Library), MEDLINE, EMBASE, CINAHL, abstracts from scientific meetings, clinical trials registries (clinicaltrials.gov; controlled-trials.com; and who.int/ictrp), Pediatric Academic Societies Annual meetings 2000 to 2014 (Abstracts2View(TM)), reference lists of identified trials, and reviews to November 2014. Preterm infants (< 32 weeks' postmenstrual age (PMA) or < 1500 g birth weight) cared for in the resuscitation area, during transport, or once admitted to a NICU or a stepdown unit. We performed data collection and analyses according to the Cochrane Neonatal Review Group. One small, high quality study assessing the effects of silicone earplugs versus no earplugs qualified for inclusion. The original inclusion criteria in our protocol stipulated an age of < 48 hours at the time of initiating sound reduction. We made a deviation from our protocol and included this study in which some infants would have been > 48 hours old. There was no significant difference in weight at 34 weeks postmenstrual age (PMA): mean difference (MD) 111 g (95% confidence interval (CI) -151 to 374 g) (n = 23). There was no significant difference in weight at 18 to 22 months corrected age between the groups: MD 0.31 kg, 95% CI -1.53 to 2.16 kg (n = 14). There was a significant difference in Mental Developmental Index (Bayley II) favouring the silicone earplugs group at 18 to 22 months corrected age: MD 14.00, 95% CI 3.13 to 24.87 (n = 12), but not for Psychomotor Development Index (Bayley II) at 18 to 22 months corrected age: MD -2.16, 95% CI -18.44 to 14.12 (n =12). To date, only 34 infants have been enrolled in a randomised controlled trial (RCT) testing the effectiveness of reducing sound levels that reach the infants' ears in the NICU. Based on the small sample size of this single trial, we cannot make any recommendations for clinical practice. Larger, well designed, conducted and reported trials are needed.
Women and Men Together in Recruit Training.
Orme, Geoffrey J; Kehoe, E James
2018-05-01
Although men and women recruits to the Australian Army have trained in mixed-gender platoons since 1995, restrictions on women joining the combat arms were only removed in 2016. As part of a longitudinal study starting with recruit training, this article examined recruit records collected before 2016 with the aims of delineating (1) the relative performance of women versus men in mixed-gender platoons and (2) the relative performance of men in mixed-gender platoons versus all-male platoons. De-identified instructor ratings for 630 females and 4,505 males who completed training between 2011 and 2015 were obtained. Recruits were distributed across 128 platoons (averaging 41.6 members, SD = 8.3) of which 75% contained females, in proportions from 5% to 45%. These analyses were conducted under defense ethics approval DPR-LREP 069-15. Factor analyses revealed that instructor ratings generally loaded onto a single factor, accounting 77.2% of the variance. Consequently, a composite recruit performance score (range 1-5) was computed for 16 of 19 competencies. Analyses of the scores revealed that the distributions of the scores for females and males overlapped considerably. Observed effects were negligible to small in size. The distributions were all centered between 3.0 and 3.5. In mixed-gender platoons, 51% of the females and 52% of the males fell in this band, and 44% of recruits in all-male platoons had scores in this band. The lower three bands (1.0-3.0) contained a slightly greater proportion of females (18%) than males in either mixed-gender platoons (12%) or all-male platoons (12%). Conversely, the upper three bands (3.5-5.0) contained a slightly smaller percentage of females (31%) than males in either mixed-gender platoons (36%) or all-male platoons (44%). Although scores for females were reliably lower than those of males in mixed-gender platoons, χ2 (4) = 16.01, p < 0.01, the effect size (V = 0.07) did not reach the criterion for even a small effect (0.10). For male recruits, those in mixed-gender platoons had scores that were reliably lower than in all-male platoons, χ2 (4) = 48.38, p < 0.001; its effect size (V = 0.11) just exceeded the criterion for a small effect (0.10). Further analyses revealed that male scores had a near-zero correlation (r = -0.033) with the proportion of females in platoons (0-45%). This large-scale secondary analysis of instructor ratings of female and male recruits provides a platform for monitoring the integration of women into the combat arms. The analyses revealed nearly complete overlap in the performance of female versus male recruits. The detected gender-related differences were negligible to small in size. These small differences must be viewed with considerable caution. They may be artifacts of rater bias or other uncontrolled features of the rating system, which was designed for reporting individual recruit performance rather than aggregate analyses. Even with these limitations, this baseline snapshot of recruit performance suggests that, at recruit training, women and men are already working well together, which bodes well for their subsequent integration into the combat arms.

Former members of armed groups in eastern DR Congo had typically witnessed, experienced, and perpetrated extreme forms of violence. Enhanced trauma-related symptoms had been shown in prior research. But also lashing out in self-defense is a familiar response to threat defined as reactive aggression. Another potential response is appetitive aggression, in which the perpetration of excessive violence is perceived as pleasurable (combat high). What roles do these forms of aggressive behavior play in modern warfare and how are they related to posttraumatic stress symptoms? To answer the question, we sought to determine predictors for appetitive aggressive and trauma-related mental illness, and investigated the frequency of psychopathological symptoms for high- and low-intensity conflict demobilization settings. To this end, we interviewed 213 former members of (para)military groups in the eastern Democratic Republic of Congo in regard to their combat exposure, posttraumatic stress, appetitive aggression, depression, suicidality, and drug dependence. Random forest regression embedded in a conditional inference framework revealed that perpetrated violent acts are not necessarily stressful. In fact, the experience of violent acts that typically implicated salient cues of hunting (e.g., blood, suffering of the victim, etc.) had the strongest association with an appetite for aggression. Furthermore, the number of lifetime perpetrated violent acts was the most important predictor of appetitive aggression. However, the number of perpetrated violent acts did not significantly affect the posttraumatic stress. Greater intensity of conflict was associated with more severe posttraumatic stress symptoms and depression. Psychotherapeutic interventions that address appetitive aggression in addition to trauma-related mental illness, including drug dependence, therefore seem indispensible for a successful reintegration of those who fought in the current civil wars.

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.

Multiple physical symptoms in a military population: a cross-sectional study
2013-01-01
Background Medically unexplained symptoms have been reported among both civilians and military personnel exposed to combat. A large number of military personnel deployed to the Gulf War in 1991 reported non-specific symptoms. These symptoms did not constitute a clearly defined syndrome. Post-traumatic stress disorder (PTSD) and to a lesser degree exposure to combat are associated with physical symptoms. Methods This is a cross-sectional study of representative samples of Sri Lanka Navy Special Forces and regular forces deployed in combat areas continuously during a 1-year period. Multiple physical symptoms were elicited using a checklist of 53 symptoms. Cases were defined as individuals with ten or more symptoms. Symptoms of common mental disorder were identified using the General Health Questionnaire 12 (GHQ-12). PTSD was diagnosed using the 17-item National Centre for PTSD checklist civilian version. Results Prevalence of multiple physical symptoms was 10.4% (95% CI 8.11–12.75). Prevalence was significantly less in the Special Forces (5.79%) than in the regular forces (13.35%). The mean number of symptoms reported by those who met the criteria for PTSD was 12.19 (SD 10.58), GHQ caseness 7.87 (SD 7.57) and those without these conditions 2.84 (SD 3.63). After adjusting for socio-demographic and service variables, ‘thought I might be killed’ , ‘coming under small arms fire’ , and ‘coming under mortar, missile and artillery fire’ remained significant. Multiple physical symptoms were associated with functional impairment and poor perceived general health. Conclusions Prevalence of multiple physical symptoms was significantly lower in the Special Forces despite high exposure to potentially traumatic events. More multiple physical symptoms were reported by personnel with PTSD and common mental disorders. Multiple physical symptoms were associated with functional impairment. PMID:23866109

Understanding the epidemiology of death after battlefield injury is vital to combat casualty care performance improvement. The current analysis was undertaken to develop a comprehensive perspective of deaths that occurred after casualties reached a medical treatment facility. Battle injury died of wounds (DOW) deaths that occurred after casualties reached a medical treatment facility from October 2001 to June 2009 were evaluated by reviewing autopsy and other postmortem records at the Office of the Armed Forces Medical Examiners (OAFME). A panel of military trauma experts classified the injuries as nonsurvivable (NS) or potentially survivable (PS), in consultation with an OAFME forensic pathologist. Data including demographics, mechanism of injury, physiologic and laboratory variables, and cause of death were obtained from the Joint Theater Trauma Registry and the OAFME Mortality Trauma Registry. DOW casualties (n = 558) accounted for 4.56% of the nonreturn to duty battle injuries over the study period. DOW casualties were classified as NS in 271 (48.6%) cases and PS in 287 (51.4%) cases. Traumatic brain injury was the predominant injury leading to death in 225 of 271 (83%) NS cases, whereas hemorrhage from major trauma was the predominant mechanism of death in 230 of 287 (80%) PS cases. In the hemorrhage mechanism PS cases, the major body region bleeding focus accounting for mortality were torso (48%), extremity (31%), and junctional (neck, axilla, and groin) (21%). Fifty-one percent of DOW casualties presented in extremis with cardiopulmonary resuscitation upon presentation. Hemorrhage is a major mechanism of death in PS combat injuries, underscoring the necessity for initiatives to mitigate bleeding, particularly in the prehospital environment.

Nowadays, technologies like improved reality systems, sensing systems and communication systems, are moving forward with a high rate. This situation is very convenient for military groups that are trying to access modern technologies. According to that, it is very feasible to propose the development of electronic devices that increase the possibilities for soldiers to be alive during an armed conflict, providing them with information that can bring strategic benefits on the combat field, which is the main goal of this research. Therefore, it is proposed in this paper the early design stages of a smart army helmet, focusing in their low cost production; however, all the electronics stages specified here are proposed as prototypes.
Pilot study of Internet-based early intervention for combat-related mental distress.
Van Voorhees, Benjamin W; Gollan, Jackie; Fogel, Joshua
2012-01-01
This article evaluates an Internet-based early intervention combining online cognitive-behavioral therapy (CBT) with electronic peer-to-peer support intended to promote mental health and well-being among combat veterans. We conducted a phase 1 clinical trial of 50 Iraq and Afghanistan veterans using a pre and post single-arm design. We evaluated feasibility and changes in mental health symptoms (depression and posttraumatic stress disorder [PTSD]), functional status, and attitudes toward treatment seeking at baseline and weeks 4, 8, and 12. A diverse group of veterans was enrolled (26% ethnic minority, 90% male, 66% with income <$30,000/year, 88% with no prior treatment for depression). Participants completed a mean of 4 of 6 lessons (standard deviation = 2.54). From baseline to week 12, there were significant declines in the Center for Epidemiologic Studies-Depression scale score (effect size [ES] = 0.41) and PTSD Checklist-Military version score (ES = 0.53). There were significant improvements in willingness to accept diagnosis (ES = 1.08) and perceived social norms and stigma regarding friends (ES = 1.51). Although lack of a control group is a limitation, the Internet-based program combining CBT-based coping skills training and peer-to-peer support demonstrated potential feasibility and evidenced benefit in symptom remediation for depression and PTSD.

To determine the prevalence of ocular disorders among Polish soldiers returning from Iraq and Afghanistan military campaigns. A retrospective review of medical records of the Military Medical Commission of Lodz, Poland was performed. Records of 296 randomly selected soldiers, including 98 who returned from Iraq in 2004 and in 198 who returned from Afghanistan in 2012, were assessed. All subjects underwent comprehensive ocular examinations according to the military regulations. We used statistical analysis to review the results. The incidence of ocular disorders in Iraq and Afghanistan groups was 17.3% and 15.1%, respectively. The study revealed that the most common disorders among soldiers were refractive errors affecting 6.8% subjects, followed by defective color vision (4.7%) and solar retinopathy (3.0%). Combat injuries were diagnosed in 3 subjects, including 2 cases of corneal injury and 1 case of retinal detachment due to blast exposure. Combat injuries occurred in 1% of soldiers returning from Iraq and Afghanistan military campaigns. There were no statistically significant differences between Iraq and Afghanistan groups in the incidence of ocular disorders. Solar retinopathy was the most common problem related to the long-term exposure to rough climate conditions in both groups. ocular findings, Iraq, Afghanistan.

This article analyzes how the behaviors of leaders and peers affect the performance and well-being of military women. Locating our analysis within the conceptual model in this issue, we summarize the empirical literature and make practice and policy recommendations. We synthesize results about unit integration, such as research on the conditions for successful integration of previously excluded groups and on the relationship between cohesion and performance. We apply lessons learned from the history of diversity integration in military and civilian organizations, analyzing the treatment of military personnel by race, gender, and sexual orientation. The opening of ground combat specialties and units to women is the latest step in personnel policy changes broadening the recruitment base. We analyze research on gender integration in contemporary armed forces, focusing on positive and negative effects on women of leader and peer behaviors. We discuss conditions for successfully integrating women and those that tend to lead to failure. We analyze military women's family issues, including the effects of deployments and how leaders and peers can help ameliorate problems-or exacerbate them with inappropriate or unsupportive behavior.

Sunburn among active component service members, U.S. Armed Forces, 2002-2013.
2014-07-01
Sunburn is caused by acute overexposure to ultraviolet (UV) radiation directly from the sun or from artificial UV sources. Service members are at risk of excessive exposure to sunlight due to the nature of their military duties, which often involve working and training outdoors, and deployment to environments where UV radiation is more intense. From January 2002 through December 2013, a total of 19,172 incident cases of clinically significant sunburn were diagnosed among active component service members. Most of the cases (80.2%) were first degree sunburn. The incidence rates of sunburn diagnoses were higher among females, white non-Hispanics, younger age groups, individuals in the Marine Corps or Army, and among enlisted service members. Additionally, the rate among recruits was more than 3.5 times the rate for non-recruits. Sixty-one percent of all diagnosed cases occurred from May through July. Sunburn cases occurred in all areas of the U.S., particularly near major recruit and combat training locations. Service members are strongly advised to practice sun safety as a part of heat illness prevention, including properly using broad-spectrum sunscreen, finding or constructing shade during work and rest, wearing protective clothing and military combat eye protection items, and avoiding tanning booths and sun lamps.

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
Special issues in hearing loss prevention in the Canadian military environment

Noise can be particularly noxious to hearing in the military. The personnel regularly face a wide range of noise-hazardous situations, many of which are seldom encountered in other work environments. High noise levels are associated with the operation of small arms and large caliber weapons, combat vehicles, aircrafts, ships and vessels, and industrial equipment. This can induce permanent and temporary hearing loss, compromise speech communication, interfere with the detection and localization of sound sources and warning sounds and thus, can jeopardize life or safety of the personnel. This paper will review the essential elements of a hearing loss prevention program proposed for the Canadian Armed Forces. The ultimate goal is to preserve hearing health as well as all hearing abilities necessary for effective operations. The program has been designed to meet the noise measurement and hazard investigation procedures, limits on noise exposure, use of hearing protection and other regulatory measures contained in the Canadian Occupational Health and Safety (COHS) Regulations (Part VII: Levels of Sound), while addressing the particular nature of the military environment. The paper will focus on issues that are not typically found in other occupational environments (variable work schedules, excessive impulse noise, extended exposures, communication devices).

During the summer, primary production in the surface layers of some fjords depletes the nutrients to the degree that some arts of toxic algae dominate the flora. We describe an experiment employing a bubble curtain to lift significant amounts of nutrient-rich seawater to the light zone and provide an environment in which useful algae can survive. The motivation for the experiment is to provide a local region in which mussels can be cleansed from the effects of toxic algae. Three 100-m long, perforated pipes were suspended at 40 m depth in the Arnafjord, a side arm of the Sognefjord. Large amounts of compressed air were supplied during a period of three weeks. The deeper water mixed with the surface water and flowed from the mixing region at 5 to 15 m depth. Within a few days, the mixture of nutrient-rich water covered most of the inner portion of Arnafjord. Within 10 days, the plankton samples showed that the artificial upwelling produced the desired type of algae and excluded the toxic blooms that were occurring outside the manipulated fjord arm. The project (DETOX) is supported by the Norwegian ministries of Fisheries, Agriculture and Public Administration.
"It's what we're here for:" nurses caring for military personnel during the Persian Gulf Wars.

Military nursing service during wartime represents significant contributions to a unique type of health care. The purposes of this study were to: (1) generate themes that elucidate combat nursing experiences, (2) honor nurses who served by sharing their stories, and (3) permanently archive accounts of nursing personnel who served during the Persian Gulf Wars during the late 20th and early 21st centuries. Eleven military nurses who provided health care to American troops in the Persian Gulf participated in a historical study as part of the ongoing Nurses at War oral history project documenting the experiences of nurses during times of armed conflict. The overriding theme, "It's what we're here for," demonstrates the commitment of nurses: a commitment to care and to sacrifice. Other themes drawn from the study included lessons learned from their wartime nursing experiences, sacrifices made, and chronicles of caring. During armed conflict in the Persian Gulf Wars, military nurses' personal stories demonstrated the importance of being engaged in making meaningful professional and historical contributions. These nurses displayed professional commitment and hardiness in the face of difficult life circumstances, saying, "We did what we had to do."

Biomarkers allowing the identification of individuals with an above average vulnerability or resilience for posttraumatic stress disorder (PTSD) would especially serve populations at high risk for trauma exposure like firefighters, police officers and combat soldiers. Aiming to identify the most promising putative PTSD vulnerability markers, we conducted the first systematic review on potential imaging and non-genetic molecular markers for PTSD risk and resilience. Following the PRISMA guidelines, we systematically screened the PubMed database for prospective longitudinal clinical studies and twin studies reporting on pre-trauma and post-trauma PTSD risk and resilience biomarkers. Using 25 different combinations of search terms, we retrieved 8151 articles of which we finally included and evaluated 9 imaging and 27 molecular studies. In addition, we briefly illustrate the design of the ongoing prospective German Armed Forces (Bundeswehr) PTSD biomarker study (Bw-BioPTSD) which not only aims to validate these previous findings but also to identify novel and clinically applicable molecular, psychological and imaging risk, resilience and disease markers for deployment-related psychopathology in a cohort of German soldiers who served in Afghanistan.

In addition to common stressors, members of the U.S. Armed Forces experience a high level of stress unique to their status as service members. In an effort to combat stress, many military personnel report high levels of nicotine use. This study investigated the relationship between tobacco use and perceived stress among military members in all four armed services. Results indicate that those who use tobacco products specifically to reduce stress report significantly higher stress levels than those who do not use tobacco. Moreover, current users and those who both smoked and used smokeless tobacco were far more likely to report experiencing "a lot" of stress from a variety of sources than former or never users. Tobacco users also engaged more frequently in negative coping behaviors and relied less on the positive coping strategies used more often by former or never smokers. These findings are consistent with the larger body of literature suggesting that tobacco is not only an ineffective stress-reducing strategy, it also likely perpetuates a stress response in users. It is, therefore, critical that the military improve effective means of coping among nicotine-using troops.

Since 1987, the Spanish Armed Forces have deployed their troops in a multitude of conflicts and natural disasters worldwide. The Spanish Military Medical Corps has the ability to deploy Role 1, Role 2, and one Role 3 medical treatment facilities. It also has a Role 4 in operation, the "Gómez Ulla" Central Hospital of Defense, in Madrid. The aim of this study is to describe the type of Spanish casualties evacuated from different areas of operation to the Role 4 from 2008 to 2013. A retrospective, cross-sectional study was performed on a sample of 232 patients. Among these, 211 (91%) were noncombat casualties: 126 because of illness, 53 because of an accident, and 32 because of sports injuries. The remaining 21 (9%) were combat casualties: 11 from improvised explosive devices and 10 from gunfire. Afghanistan, followed by Lebanon, is the operational area where most evacuees originate. The authors consider it essential that the Spanish Armed Forces rely on a Role 4 medical treatment facility as part of their medical support to international operations.

The effectiveness of hearing protection devices (HPDs), when used in workplace conditions, has been shown over the years to be usually lower than the labeled values obtained under well-controlled laboratory conditions. Causes for such discrepancies have been listed and discussed by many authors. This study is an attempt to understand the issues in greater details and quantify some of these factors by looking at the performance of hearing protectors as a function of time during full work shift conditions. A non-invasive field microphone in the real ear (F-MIRE)-based method has been developed for measuring the effectiveness of different HPDs as a function of time in the workplace. Details of the test procedures, the equipment used, and the post-processing operations are presented and discussed. The methodology was developed in such a way that a complete time and frequency representation are possible. The system was used on a total of 24 workers in eight different companies. Work shifts of up to 9-h long were recorded. Various types of earmuffs and one type of molded earplugs were tested. Attenuation data reported as a function of time showed, for most workers tested, considerable fluctuations over entire work shift periods. Parts of these fluctuations are attributed to variations in the low-frequency content in the noise (in particular for earmuffs) as well as poor insertion and/or fitting of earplugs. Lower performances than laboratory-based ones were once again observed for most cases tested but also, important left and right ear differences were obtained for many individuals. When reported as a function of frequency, the attenuation results suggested that the few approximations used to relate the measurements to subjective real-ear-attenuation-at-threshold (REAT) data were realistic. The use of individualized attenuation data and performance ratings for HPDs as well as a good knowledge of the ambient noise in the workplace are key ingredients when evaluating the performance of hearing protectors in field conditions.

The purpose of our study was to identify the main factors associated with objective noise-induced hearing loss (NIHL), as indicated by abnormal audiometric testing, in Spanish workers exposed to occupational noise in the construction industry. We carried out a prospective study in Tenerife, Spain, using 150 employees exposed to occupational noise and 150 age-matched controls who were not working in noisy environments. The variables analyzed included sociodemographic data, noise-related factors, types of hearing protection, self-report hearing loss, and auditory-related symptoms (e.g., tinnitus, vertigo). Workers with pathological audiograms had significantly longer noise-exposure duration (16.2 ± 11.4 years) relative to those with normal audiograms (10.2 ± 7.0 years; t = 3.99, P < 0.001). The vast majority of those who never used hearing protection measures had audiometric abnormalities (94.1%). Additionally, workers using at least one of the protection devices (earplugs or earmuffs) had significantly more audiometric abnormalities than those using both protection measures simultaneously (Chi square = 16.07; P < 0.001). The logistic regression analysis indicates that the use of hearing protection measures [odds ratio (OR) = 12.30, confidence interval (CI) = 4.36-13.81, P < 0.001], and noise-exposure duration (OR = 1.35, CI = 1.08-1.99, P = 0.040) are significant predictors of NIHL. This regression model correctly predicted 78.2% of individuals with pathological audiograms. The combined use of hearing protection measures, in particular earplugs and earmuffs, associates with a lower rate of audiometric abnormalities in subjects with high occupational noise exposure. The use of hearing protection measures at work and noise-exposure duration are best predictive factors of NIHL. Auditory-related symptoms and self-report hearing loss do not represent good indicators of objective NIHL. Routine monitoring of noise levels and hearing status are of great importance as part of effective hearing conservation programs. PMID:26356377

The effects of war on the Colombian population.
Arboleda, Nelson
2002-01-01
In the last decade, more than 1.5 million children have died as victims of war and 2000 over 300,000 children were being used as combatants. Colombia, the fourth largest country in Latin America in terms of population and second in area, has been the site of conflict between the government and guerrilla groups, which has created over 200,000 victims and has worsened in the last five years. There is severe poverty and illegal trading in arms and narcotics is closely linked to the conflict. Kidnapping, both individual and mass and often of children, has been a particular feature. Colombia urgently needs programmes to eradicate poverty and violence and must be fully supported by international organizations. Research to suggest effective interventions is an essential part of such programmes.

The current humanitarian crisis in Yemen is unprecedented in many ways. The Yemeni War tragedy is symptomatic of gross failures to recognize, by combatants, existing humanitarian law and the Geneva Convention that have become the new norm in unconventional armed conflicts and are increasingly replicated in Africa, Afghanistan, and other areas of the Middle East with dire consequences on aid workers and the noncombatant population. The health and humanitarian professions must take collective responsibility in calling for all belligerent parties to cease the massacre and commit to guaranteed medical assistance, humanitarian aid, and the free flow of information and respect for the humanitarian principles that protect the neutrality and impartiality of the humanitarian workforce.

A recent article by Maxwell J. Mehlman and Tracy Yeheng Li, in the Journal of Law and the Biosciences , sought to examine the ethical, legal, social, and policy issues associated with the use of genetic screening and germ-line therapies ('genomic technologies') by the US Military. In this commentary, we will elaborate several related matters: the relationship between genetic and non-genetic screening methods, the history of selection processes and force strength, and the consequences and ethics of, as Mehlman and Li suggest, engineering enhanced soldiers. We contend, first, that the strengths of genomic testing as a method of determining enrollment in the armed forces has limited appeal, given the state of current selection methods in the US armed forces. Second, that the vagaries of genetic selection, much like other forms of selection that do not bear causally or reliably on soldier performance (such as race, gender, and sexuality), pose a systematic threat to force strength by limiting the (valuable) diversity of combat units. Third, that the idea of enhancing warfighters through germ-line interventions poses serious ethical issues in terms of the control and ownership of 'enhancements' when members separate from service.
Wearable Pulse Oximetry Measurements on the Torso, Arms, and Legs: A Proof of Concept.

For decades pulse oximeters designed for use on the head, hands, or feet have provided invaluable estimates of oxygen saturation to medical personal attending to combat casualties. However, traditional placement sites are not ideal for the relatively new paradigm of continuous battlefield telemonitoring. To assess the feasibility of oximetry on nontraditional body sites, 42 healthy volunteers were enrolled, consented, and underwent an industry standard induced-hypoxia study. During the study volunteers used prototype wearable oximeters, designed for the torso, arms, and legs. Subsets (size n) of the volunteers had the wearables placed at the following body sites, and achieved accuracies (A RMS , root-mean-square difference) of the following: calf 1.7% (n = 26); bicep 3.1% (n = 12); forearm 3.4% (n = 11); pectoral 2.9% (n = 42); sternum 2.9% (n = 13). In keeping with regulatory guidance calibrations with an A RMS of less than 3.5% are acceptable for potential future development. Additionally, a new method was developed to enable accurate reporting of respiration rate from the pectoral oximeter, A RMS of 1.1 breaths per minute (n = 10). This study demonstrates the feasibility of monitoring oxygen saturation and respiration rate from nontraditional sites via a wearable pulse oximeter.

To evaluate the safety and efficacy of sildenafil citrate for treating erectile dysfunction (ED) in patients with combat-related post-traumatic stress disorder (PTSD). In all, 266 combat-exposed war veterans with ED (aged 37-59 years) were recruited. They met the Diagnostic and Statistical Manual of Mental Disorders-IV criteria for PTSD according to the Structured Clinical Interview for Patients, Investigator Version. The patients were also evaluated with the Clinician-Administered PTSD Scale, both to establish the diagnosis of PTSD and to measure symptom severity. Only patients with psychogenic ED were included in the study. Patients with comorbid conditions (diabetes mellitus, hypercholesterolaemia, hypertension, Peyronie's disease) and smokers of more than five cigarettes daily were excluded. The patients were randomly divided into a group of 133 who received 100 mg of on-demand sildenafil 0.75-2 h before sexual stimulation, and 133 who received placebo. Patients were asked to use > or =16 doses or attempts at home. The efficacy of the treatments was assessed every four attempts during treatment, and at the end of the study, using responses to the 15-question International Index of Erectile Function (IIEF), Sexual Encounter Profile diary questions 2 and 3, Erectile Dysfunction Inventory of Treatment Satisfaction questionnaire, patients' event logs of sexual activity, and a Global Assessment Question about erections. Sildenafil did not produce significantly and substantially greater improvement than placebo in each of the primary and secondary outcome measures (P = 0.08). A normal EF domain score (> or =26) at endpoint was reported by 13 (9.8%), and 11 (8.3%) of patients on the sildenafil and placebo regimens, respectively (P = 0.09). Patients treated with sildenafil had no statistically significantly greater improvement in the five sexual function domains of the IIEF questionnaire than those treated with placebo (P = 0.08). The incidences of treatment-emergent adverse events were significantly greater in the sildenafil arm than in the placebo group (P = 0.01). Sildenafil is no better than placebo in treating PTSD-emergent ED. Further randomized clinical trials are warranted in combat veterans and other populations with PTSD to better elucidate the role of phosphodiesterase type 5 inhibitors in treating PTSD-emergent ED.

Background Depending on the exposure to traumatic stressors and combat, 20% to 50% of ex‐combatants present with trauma‐related disorders, and more than half of the members of armed groups have a proclivity to violence. Therefore, psychotherapeutic assistance should address both, trauma‐related suffering and the lowered threshold for aggressive behaviour. Objective Supporting the demobilization process of ex‐combatants in the eastern DR‐Congo, we implemented a version of Narrative Exposure Therapy adapted for Forensic Offender Rehabilitation (FORNET). Method In two successive dissemination stages (DS), local counsellors conducted FORNET. In DS1, they were trained by clinical experts, and in DS2, the by then experienced counsellors trained and supervised a second group of local counsellors (DS2). The training consisted of a 3‐week workshop covering theoretical concepts and practical therapeutic skills. In DS1 and DS2, a total of 98 demobilizing combatants received an intervention; treatment‐as‐usual served as the control condition. Posttraumatic stress disorder, appetitive aggression, depression severity and drug dependence were assessed prior to the intervention and 6 and 12 months later; additionally, we assessed reintegration success. Results Six months post‐intervention, FORNET significantly reduced Posttraumatic stress disorder symptoms but had less effect on the trait of appetitive aggression; moreover, beneficial effects were found for depression severity and drug dependence as well as for reintegration indices. Treatment gains were retained at 12 months. Conclusions Individuals without previous training in psychotherapy can learn to effectively apply the brief intervention FORNET and support the demobilization process in ongoing conflicts. The study suggests that it is possible to pass down psychotherapeutic techniques over generations of counsellors. © 2015 The Authors.

To describe the mechanisms, burden of injury, inpatient management and rehabilitation requirements of wounded military personnel at the UK Role 4 (R4) facility within the first 12 months following cessation of combat operations in Afghanistan. All aeromedical evacuations were recorded prospectively between October 2014 and October 2015. Demographic, logistical and clinical data were derived manually from referring medical unit and patient movement requests in addition to host nation and R4 medical records. Ninety-five patients were repatriated to R4 following traumatic injury: 98.9% (n=94) were male, and median age was 27 years (IQR 25-36 years). The most common mechanisms of injury (MOIs) were sports 26.3% (n=25), falls <2 m 11.6% (n=11) and road traffic collisions 9.8% (n=9). The most common anatomical regions of injury were isolated lower limb 24.1% (n=22), isolated hand 20.0% (n=19) and polytrauma 14.7% (n=14). Median Injury Severity Score was 4 (IQR 4-9), mean 8 (range 1-41). Eleven patients (11.6%) were discharged to rehabilitation units, of whom 7 (63.6%) required neurorehabilitation. Although service personnel sustain civilian-type injuries, the specific rehabilitation goals and shift in the acute rehabilitation requirements for military personnel must be considered in the absence of enduring combat operations. It is notable that permanent medical downgrading secondary to trauma still occurs outside of warfare. The colocation of civilian major trauma services and R4 has ensured a mutually beneficial partnership that contributes to institutional memory and improves the coordination of patient pathways. The importance of relevant resource allocation, training, support and logistical considerations remain, even during the current scale of military activity overseas. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Previous studies regarding combat wounding have a limited translational capacity due to inclusion of soldiers from all military branches and occupational specialties as well as a lack of information regarding soldiers who died in theater. A search was performed of the Department of Defense Trauma Registry and Armed Forces Medical Examiner data set for the years 2003 to 2011 to identify all injured personnel with the military specialty 19D (cavalry scout). A manual search was conducted for each record identified, and age, rank, location and manner of injury, mechanism of injury, Injury Severity Score (ISS), and extent of wounding were abstracted. The incidence of injuries by body region and rates for specific types of wounds were determined. Statistically significant associations between rank, location of injury, manner of injury, body region involved, and injury mechanism were assessed using χ2 analysis. Associations between ISS, rank, manner of injury, and survival were evaluated by t test with Satterthwaite correction. A total of 701 casualties were identified with 3,189 distinct injuries. Mean (SD) age of injured personnel was 25.9 (6.0) years. Thirty-five percent of the cohort was composed of soldiers who died in theater. Explosions were the most common mechanism of injury (70%), while 18% of wounds occurred owing to gunshot. Extremity wounds and injuries to the head and neck represented 34% of casualty burden. Thoracic trauma occurred in 16%, and abdominal injuries occurred in 17%. Wounds with a frequency exceeding 5% included skin, extremity, facial, brain, and gastrointestinal injuries. Vascular injury occurred in 4%. Gunshot wounds were a greater cause of injury in Afghanistan (p = 0.001) and resulted in a higher percentage of thoracic injuries (p < 0.001). The nature and extent of trauma sustained by combat-specific personnel seems to be different from that experienced by all soldiers deployed to a war zone.

There is growing concern about an alleged rise in violent behaviour amongst military personnel returning from deployment to Iraq and Afghanistan. The aims of this study were to determine the prevalence of violence in a sample of U.K. military personnel following homecoming from deployment in Iraq and to examine the impact of deployment-related experiences, such as combat trauma, on violence, and the role of sociodemographics and pre-enlistment antisocial behaviour. This study used baseline data from a cohort study of a large randomly selected sample of U.K. Armed Forces personnel in service at the time of the Iraq war (2003). Regular personnel (n=4928) who had been deployed to Iraq were included. Data, collected by questionnaire, included information on deployment experiences, sociodemographic and military characteristics, pre-enlistment antisocial behaviour, post-deployment health outcomes and a self-report measure of physical violence in the weeks following return from deployment. Prevalence of violence was 12.6%. This was strongly associated with pre-enlistment antisocial behaviour [adjusted odds ratio (aOR) 3.6, 95% confidence interval (CI) 2.9-4.4]. After controlling for pre-enlistment antisocial behaviour, sociodemographics and military factors, violence was still strongly associated with holding a combat role (aOR 2.0, 95% CI 1.6-2.5) and having experienced multiple traumatic events on deployment (aOR for four or more traumatic events 3.7, 95% CI 2.5-5.5). Violence on homecoming was also associated with mental health problems such as post-traumatic stress disorder (aOR 4.8, 95% CI 3.2-7.2) and alcohol misuse (aOR 3.1, 95% CI 2.5-3.9). Experiences of combat and trauma during deployment were significantly associated with violent behaviour following homecoming in U.K. military personnel. Post-deployment mental health problems and alcohol misuse are also associated with increased violence.

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.
Women in war: operational issues of menstruation and unintended pregnancy.
Christopher, Leslie A; Miller, Leslie
2007-01-01
With rapid and frequent deployments around the world, the current high level of military operations demands combat readiness of every military member. In the U.S. Armed Forces, women represent 15% of active duty troops and 17% of reserve and Guard troops and are a critical component for mission accomplishment. The operational issues of menstruation and unintended pregnancy, unique to this population, can decrease a female member's military readiness and affect her ability to deploy. Strategies to mitigate and even eliminate these concerns include the optional use of hormonal medications to induce reversible menstrual cycle suppression. These medications, traditionally indicated for contraception, should be considered essential for female troops during training and deployment. This article, tailored specifically for military women, provides valuable information regarding the risks and benefits, as well as the various options available for menstrual cycle suppression.
[Psychophysiological support for the professional activities of servicemen].

1998-11-01
Optimal solution of the personnel replenishment problem, the necessity of training and education process improvement in the training centers and schools, the outcome of social, psychological and medical measures greatly depend on the overall physical and mental health state of the servicemen and their professional training quality. On the basis of their long standing experience the authors discuss the traits of the psychophysiological maintenance of the military professional activities of servicemen, in particular--the methodology and theory of professional psychological selection, the importance of body functional indications for the estimation of the fighting capabilities of military units. They examine some prospects for the psychophysiological expertise in the promotion procedures of commanding officers and make a suggestion that psychophysiological maintenance in the Armed Forces would increase its combat capabilities and help to avoid some negative effects in military groups.
Acute closed radial nerve injury

2011-01-01
We present a 45-year-old patient who had acute radial nerve palsy following a blunt trauma without any fracture or dislocation. He was injured by strucking in a combat three months ago. The patient has been followed by application of a long-arm plaster cast before referred to our clinic. Preoperative electromyoneurography and magnetic resonance imaging (MRI) indicated that there was a radial nerve injury on humeral groove. The British Medical Research Council (MRC) grade was 2/5 on his wrist preoperatively. The patient underwent an operation under general anesthesia. It was seen to be a second-degree nerve injury. The patient has subsequently regained full movement on his wrist and finger extension in six months. We suggest that a detailed clinical and electrodiagnostical evaluation is necessary in patients who have radial nerve injury when deciding the treatment, conservative or surgical. PMID:22347334

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 objective of the study was to develop a simple device, Vertical accelerator (Vertac), to apply vertical impact loads to Post Mortem Human Subject (PMHS) or dummy surrogates because injuries sustained in military conflicts are associated with this vector; example, under-body blasts from explosive devices/events. The two-part mechanically controlled device consisted of load-application and load-receiving sections connected by a lever arm. The former section incorporated a falling weight to impact one end of the lever arm inducing a reaction at the other/load-receiving end. The "launch-plate" on this end of the arm applied the vertical impact load/acceleration pulse under different initial conditions to biological/physical surrogates, attached to second section. It is possible to induce different acceleration pulses by using varying energy absorbing materials and controlling drop height and weight. The second section of Vertac had the flexibility to accommodate different body regions for vertical loading experiments. The device is simple and inexpensive. It has the ability to control pulses and flexibility to accommodate different sub-systems/components of human surrogates. It has the capability to incorporate preloads and military personal protective equipment (e.g., combat helmet). It can simulate vehicle roofs. The device allows for intermittent specimen evaluations (x-ray and palpation, without changing specimen alignment). The two free but interconnected sections can be used to advance safety to military personnel. Examples demonstrating feasibilities of the Vertac device to apply vertical impact accelerations using PMHS head-neck preparations with helmet and booted Hybrid III dummy lower leg preparations under in-contact and launch-type impact experiments are presented.

Childhood overweight and obesity is a public health epidemic with far-reaching medical, economic, and quality of life consequences. Brief, web-based interventions have received increased attention for their potential to combat childhood obesity. The purpose of our study was to evaluate a web-based, maternal-facilitated childhood obesity prevention intervention dubbed Enabling Mothers to Prevent Pediatric Obesity Through Web-Based Education and Reciprocal Determinism (EMPOWER), for its capacity to elicit sustained effects at the 2-year postintervention follow-up mark. Two interventions were evaluated using a randomized controlled trial design. The experimental, EMPOWER arm received a social cognitive theory intervention ( n = 29) designed to improve four maternal-facilitated behaviors in children (fruit and vegetable consumption, physical activity, sugar-free beverage intake, screen time). The active control arm received a knowledge-based intervention dubbed Healthy Lifestyles ( n = 28), which also targeted the same four behaviors. We identified a significant group-by-time interaction of small effect size for child fruit and vegetable consumption ( p = .033; Cohen's f = 0.139) in the EMPOWER group. The construct of maternal-facilitated environment was positively associated to improvements in child fruit and vegetable behavior. We also found significant main effects for child physical activity ( p = .024; Cohen's f = 0.124); sugar-free beverage intake ( p < .001; Cohen's f = 0.321); and screen time ( p < .001; Cohen's f = 0.303), suggesting both groups improved in these behaviors over time. The EMPOWER arm of the trial resulted in an overall increase of 1.680 daily cups of fruits and vegetables consumed by children, relative to the comparison group ( p < .001, 95% confidence interval = [1.113, 2.248]). Web-based maternal-facilitated interventions can induce sustained effects on child behaviors.

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.

This review summarizes the epidemiology of posttraumatic stress disorder (PTSD) and related mental health problems among persons who served in the armed forces during the Iraq and Afghanistan conflicts, as reflected in the literature published between 2009 and 2014. One-hundred and sixteen research studies are reviewed, most of which are among non-treatment-seeking US service members or treatment-seeking US veterans. Evidence is provided for demographic, military, and deployment-related risk factors for PTSD, though most derive from cross-sectional studies and few control for combat exposure, which is a primary risk factor for mental health problems in this cohort. Evidence is also provided linking PTSD with outcomes in the following domains: physical health, suicide, housing and homelessness, employment and economic well-being, social well-being, and aggression, violence, and criminality. Also included is evidence about the prevalence of mental health service use in this cohort. In many instances, the current suite of studies replicates findings observed in civilian samples, but new findings emerge of relevance to both military and civilian populations, such as the link between PTSD and suicide. Future research should make effort to control for combat exposure and use longitudinal study designs; promising areas for investigation are in non-treatment-seeking samples of US veterans and the role of social support in preventing or mitigating mental health problems in this group.

The illicit trafficking in small arms is an international problem with grave consequences to those who live in less developed nations. To stop any form of trafficking it is important to ensure the ability to track weapons to their sources, there must be a common international system for the marking and tracing of weapons. Under current international law, states may adopt various different weapons marking systems, complicating the identification of the country-of-origin of a weapon [1]. However, these marking technologies are only good for those firearms that are recovered or captured. By instituting Intentional Firearm Microstamping (IFM) a technology that provides a link to a serial or production build number, by embossing the IFM code on to the cartridge that is fired and ejected at the scene. IFM will provide critical forensic intelligence in regions of conflict by helping to identify patterns, trafficking routes and ultimately shut down illicit arms sources and markets that fuel the violence associated with regional genocide, terrorism and/or insurgency groups within warzones. Intentional Firearm Microstamping (IFM) technology will provide a rapid and accurate cartridge-to-firearm identification process, enabling law enforcement both national and international to quickly pursue international arms dealers and other illicit firearm markets. Intentional Firearm Microstamping (IFM) is a patented technology and trace solution where intentional tooling marks are formed or micromachined onto firearms interior surfaces that come into contact or impact the surfaces of cartridge casings. The IFM tooling marks can take the form of alphanumeric codes or encoded geometric codes, such as a barcode. As the firearm is discharged the intentional tooling marks transfer a code to the cartridge casing before it is ejected out of the firearm. When recovered at the scene of an incident, the intentional firearm microstamped cartridge can indentify a specific firearm, without the need to recover that firearm. This paper will explain the key attributes of Intentional Firearm Microstamping technology; including its implementation and application benefits such as developing border security controls and law enforcement capacity world wide to combat illicit trafficking of firearms to terrorists, gangs and/or fueling regional conflicts. The data generated by IFM will be discussed and its application to spatial and temporal mapping of trafficking patterns and other criminal patterns.

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.
Monoclonal antibodies for diagnosis and treatment.
Dunn, D L

One of the marvels of the host immune response is its response to antigenic foreign substances by manufacturing proteins that bind tenaciously to their targets. These proteins are antibodies or immunoglobulins produced in vast diversity during an individual's lifetime. By virtue of this process, the mammalian host possesses the innate ability to mount an initial response to antigens to which there has been no prior experience and to develop an even more effective response on reexposure to these same substances. This capacity to distinguish self from nonself is one of the most basic aspects of the cellular and humoral arms of the immune response and is one of the primary means by which the host combats infection caused by many different types of pathogens. In this context, antibodies have long been recognized as a critical component of host defenses and are capable of binding to invading microbes and microbial toxins.

In a bilingual paper entitled 'Bibliometrics as weapons of mass citation--La bibliométrie comme arme de citation massive', recently translated into English, we have argued that the current fashion of ranking people, papers and journals is anything but harmless. The point was forcefully supported by Richard Ernst in a post-face entitled 'The Follies of Citation Indices and Academic Ranking Lists. We received a surprising number of passionate responses, such as 'It's written out of my heart' (TH); 'Je soutiens cette entreprise courageuse de tout coeur' (VT); 'Impact Faktoren sind ein Marktinstrument gewisser Verlage (FS); 'II y a un combat à mener' (SB). Some thoughtful responses have been incorporated into this Essay, albeit in attenuated form. We suggest that the 'fertility' of individual scientists be appreciated in terms of kinship rather than through personalized indices.

To improve the survival of combat casualties, interest in the earliest resort to whole blood (WB) transfusion on the battlefield has been emphasized. Providing volume, coagulation factors, plasma, and oxygenation capacity, WB appears actually as an ideal product severe trauma management. Whole blood can be collected in advance and stored for subsequent use, or can be drawn directly on the battlefield, once a soldier is wounded, from an uninjured companion and immediately transfused.Such concepts require a great control of risks at each step, especially regarding ABO mismatches, and transfusion-transmitted diseases. We present here the "warm and fresh" WB field transfusion program implemented among the French armed forces. We focus on the followed strategies to make it applicable on the battlefield, even during special operations and remote settings, and safe for recipients as well as for donors.

Brachial plexus injury in a patient under general anesthesia (GA) is not uncommon, despite careful positioning and, particularly, awareness of the possibility. The mechanism of injury is stretching and compression of the brachial plexus over a prolonged period. Positioning the patient within the computed tomography (CT) gantry for abdominal or chest procedures can simulate a surgical procedure, particularly when GA is used. The potential for brachial plexus injury is increased if the case is prolonged and the patient's arms are raised above the head to avoid CT image degradation from streak artifacts. We report a case of profound brachial plexusmore » palsy following a CT-guided radiofrequency ablation procedure under GA. Fortunately, the patient recovered completely. We emphasize the mechanism of injury and detail measures to combat this problem, such that radiologists are aware of this potentially serious complication.« less

The authors report on an advertising campaign to communicate the availability and desirability of using Sexual Assault Nurse Examination (SANE) services. They used social marketing precepts to develop posters to educate college students about using SANE as a health service and as an arm of prosecution. After 2 advertising campaigns, they conducted an anonymous survey of 1,051 college students. The findings indicated that posters placed in residence halls and public bathrooms reached students, produced a statistically significant increase in students' understanding of SANE services, and were significantly associated with their hypothetical encouragement of others to use SANE. Gender mediated some results. Posters placed in private viewing spaces were found to be a viable way to communicate information about SANE. Funding to combat violence against women on campus should be aimed at increasing students' access to SANE and should include the costs of advertising the program.

A small proportion of servicemen enlisting for compulsory National Service in Singapore experience problems adjusting to military life. This paper aims to profile the servicemen who experience such problems. There is a paucity of literature addressing this issue internationally and none published locally. Servicemen who were referred to the Psychological Medicine Branch of the Singapore Armed Forces within six months of enlistment were retrospectively studied. In the work year July 1995 to June 1996, 77 cases were seen. The main classes of diagnoses were stress-related disorders, anxiety, mood and psychotic disorders. The main stressor was problems adapting to the military environment. There were 10 cases of parasuicide, significantly less than US Army statistics. At Operationally Ready Date, 20.7% were able to hold a combat vocation, similar to the US Army situation. This paper hopes to document the local figures and act as a reference for evaluating future therapies and policies.

It is 60 years since the bombing of Pearl Harbor and the outbreak of World War II for the United States. Some of the men and women who served in the armed forces at the time are willing to share some of their reminiscences with those of us who could not serve for one reason or another or who may not even have been born at the time. One of the dentists who is willing to share some of his memories is Dr. Charles Q. Orden of New York. Unless these people share their memories much history will be lost forever in the next years, and we will all be poorer for it. We sincerely thank Dr. Orden for his offer of information and for allowing us to reproduce Fig. 1 in which he is seen as the dentist using a field dental chair, a foot-powered drill, and with a black dental corpsman as his assistant.

The principle difference of the work of multiprofile military hospitals (MMH) of the Ist level during the armed conflicts on the Northern Caucasus, particularly during the second, was rendering specialized surgical care to the primary contingent of the wounded, evacuated during the nearest hours after a wound. The incoming flow to MMH of the 1st level - in connection with the primary entering of the wounded practically from a battle field - was characterized by severity (one third of the wounded had severe and extremely severe wounds) and the significant number of the wounded with multiple and combined injuries (up to 60% of the wounded). Effective treatment of the above-mentioned wounded can only be carried by specially trained surgeons in appropriately-equipped multiprofile medical hospitals. The rendered volume of specialized surgical care in MMH of the 1st level included the following operations: neurosurgical (2,4%), thoracoabdominal (19,8%), traumatologic (17,0%), angiosurgical (8,2%), special (otorhinolaryngologic, maxillofacial, ophthalmologic, urologic) - 17,7%, general surgery (35,4%). During the armed conflict of 1999-2002 due to the introduction of the early specialized surgical care concept three MMH of the 1st level in the advanced way executed 86,4 % of all complex operations in medical units and hospitals of the combat zone.

The fourth annual Extremity War Injuries (EWI) Symposium addressed ongoing challenges and opportunities in the management of combat-related musculoskeletal injury. The symposium, which also examined host-nation care and disaster preparedness and response, defined opportunities for synergy between several organizations with similar missions and goals. Within the Department of Defense, the Orthopaedic Extremity Trauma Research Program (OETRP) has funded basic research related to a series of protocols first identified and validated at prior EWI symposia. A well-funded clinical research arm of OETRP has been developed to help translate and validate research advances from each of the protocols. The Armed Forces Institute for Regenerative Medicine, a consortium of academic research institutions, employs a tissue-engineering approach to EWI challenges, particularly with regard to tissue loss. Programs within the National Institute of Arthritis and Musculoskeletal and Skin Diseases and throughout the National Institutes of Health have also expanded tissue-engineering efforts by emphasizing robust mechanistic basic science programs. Much of the clinical care delivered by US military medical personnel and nongovernmental agencies has been to host-nation populations; coordinating delivery to maximize the number of injured who receive care requires understanding of the breadth and scope of resources available within the war zone. Similarly, providing the most comprehensive care to the greatest number of injured in the context of domestic mass casualty requires discussion and planning by all groups involved.

Between February and May 2010, 1st Battalion, 6th Marines reported a 10% (10/92) breakage rate for tourniquets. One theory suggested was that tourniquets were weakened by exposure to the Afghan environment. Our study was designed to compare three groups of Afghanistan-exposed tourniquets to unexposed tourniquets. The three experimental arms were: (1) Afghan-exposed tourniquets worn on the plate carrier, (2) Afghan-exposed tourniquets carried in the Individual First Aid Kit (IFAK) and wrapped in manufacturer plastic wrapping, and (3) Afghan-exposed tourniquets carried in the IFAK with the manufacturer plastic wrapping removed. The outcome measures of this study were efficacy, breakage, and number of turns required to successfully stop the distal pulse. Tourniquets worn on the plate carrier had an efficacy of 57%, which was significantly lower than the control efficacy rate of 95.2%. When compared to the control arm, there were no significant differences in efficacy between the tourniquets stored in the IFAK with or without manufacturing packaging. No control tourniquets or tourniquets stored in IFAKs broke; however, 46 (12%) of the plate carrier-exposed tourniquets did break. No statistically significant differences were found between the four groups with regard to the median number of turns required to stop the distal pulse.

The Just War Theory and the ethical governance of research.
Malsch, Ineke
2013-06-01
This article analyses current trends in and future expectations of nanotechnology and other key enabling technologies for security as well as dual use nanotechnology from the perspective of the ethical Just War Theory (JWT), interpreted as an instrument to increase the threshold for using armed force for solving conflicts. The aim is to investigate the relevance of the JWT to the ethical governance of research. The analysis gives rise to the following results. From the perspective of the JWT, military research should be evaluated with different criteria than research for civil or civil security applications. From a technological perspective, the boundaries between technologies for civil and military applications are fuzzy. Therefore the JWT offers theoretical grounds for making clear distinctions between research for military, civil security and other applications that are not obvious from a purely technological perspective. Different actors bear responsibility for development of the technology than for resorting to armed force for solving conflicts or for use of weapons and military technologies in combat. Different criteria should be used for moral judgment of decisions made by each type of actor in each context. In addition to evaluation of potential consequences of future use of the weapons or military technologies under development, the JWT also prescribes ethical evaluation of the inherent intent and other foreseeable consequences of the development itself of new military technologies.

Pump mediated drug efflux is the key reason to result in the failure of chemotherapy. Herein, a novel star polymer β-CD-v-(PEG-β-PNIPAAm) 7 consisting of a β-CD core, grafted with thermo-responsive poly(N-isopropylacrylamide) (PNIPAAm) and biocompatible poly(ethylene glycol) (PEG) in the multiple "V"-shaped arms is designed and further fabricated into supramolecular nanocarriers for drug resistant cancer therapy. The star polymer could encapsulate chemotherapeutics between β-cyclodextrin and anti-cancer drug via inclusion complex (IC). Furthermore, the temperature induced chain association of PNIPAAm segments facilitated the IC to form supramolecular nanoparticles at 37 °C, whereas the presence of PEG impart great stability to the self-assemblies. When incubated with MDR-1 membrane pump regulated drug resistant tumor cells, much higher and faster cellular uptake of the supramolecular nanoparticles were detected, and the enhanced intracellular retention of drugs could lead to significant inhibition of cell growth. Further in vivo evaluation showed high therapeutic efficacy in suppressing drug resistant tumor growth without a significant impact on the normal functions of main organs. This work signifies thermo-responsive supramolecular chemotherapy is promising in combating pump mediated drug resistance in both in vitro and in vivo models, which may be encouraging for the advanced drug delivery platform design to overcome drug resistant cancer. © 2017 WILEY-VCH Verlag GmbH & Co.

The capabilities of flat panel interventional x-ray systems continue to expand, enabling a broader array of medical applications to be performed in a minimally invasive manner. Although CT is providing pre-operative 3D information, there is a need for 3D imaging of low contrast soft tissue during interventions in a number of areas including neurology, cardiac electro-physiology, and oncology. Unlike CT systems, interventional angiographic x-ray systems provide real-time large field of view 2D imaging, patient access, and flexible gantry positioning enabling interventional procedures. However, relative to CT, these C-arm flat panel systems have additional technical challenges in 3D soft tissue imaging including slower rotation speed, gantry vibration, reduced lateral patient field of view (FOV), and increased scatter. The reduced patient FOV often results in significant data truncation. Reconstruction of truncated (incomplete) data is known an "interior problem", and it is mathematically impossible to obtain an exact reconstruction. Nevertheless, it is an important problem in 3D imaging on a C-arm to address the need to generate a 3D reconstruction representative of the object being imaged with minimal artifacts. In this work we investigate the application of an iterative Maximum Likelihood Transmission (MLTR) algorithm to truncated data. We also consider truncated data with limited views for cardiac imaging where the views are gated by the electrocardiogram(ECG) to combat motion artifacts.
Mechanical, physical, and physiological analysis of symmetrical and asymmetrical combat.
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.

The stress of multiple combat tours has created a combat-tested but combat-weary Army. While most soldiers have coped successfully with combat stress, many return home with problems that include posttraumatic stress disorder (PTSD), depression, anxiety, aggressive behavior, insomnia, and reduced memory and concentration skills.

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

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.

A formulation and analysis of combat games

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.
Reliability and validity of a combat exposure index for Vietnam era veterans.

1991-01-01
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.

Severe noncompressible torso hemorrhage remains a leading cause of potentially preventable death in modern military conflicts. Resuscitative endovascular occlusion of the aorta (REBOA) has demonstrated potential as an effective adjunct to the treatment of noncompressible torso hemorrhage in the civilian early hospital and even prehospital settings-but the application of this technology for military prehospital use has not been well described. We aimed to assess the feasibility of both field and en route prehospital REBOA in the military exercise setting, simulating a modern armed conflict. Two adult male Sus Scrofa underwent simulated junctional combat injury in the context of a planned military training exercise. Both underwent zone I REBOA in conjunction with standard tactical combat casualty care interventions-one during point of injury care and the other during en route flight care. Animals were sequentially evacuated to two separate forward surgical teams by rotary wing platform where the balloon position was confirmed by chest x-ray. Animals then underwent different damage control thoracic and abdominal procedures before euthanasia. The first swine underwent immediate successful REBOA at the point of injury 7 minutes and 30 seconds after the injury. It required 6 minutes total from initiation of procedure to effective aortic occlusion. Total occlusion time was 60 minutes. In the second animal, the REBOA placement procedure was initiated immediately after take off (17 minutes and 40 seconds after the injury). Although the movements and vibration of flight were not significant impediments, we only succeeded to put a 6-French (Fr) sheath into a femoral artery during the 14 minutes flight due to lighting and visualization challenges. After the sheath had been upsized in the forward surgical team, the REBOA catheter was primarily placed in zone I followed by its replacement to zone III. Both animals survived to study completion and the termination of training. No complications were observed in either animal. Our study demonstrates the potential feasibility of REBOA for use during tactical field and en route (flight) care of combat casualties. Further study is needed to determine the optimal training and utilization protocols required to facilitate the effective incorporation of REBOA into military prehospital care capabilities.
The mental health of the UK Armed Forces: where facts meet fiction

A substantial amount of research has been conducted into the mental health of the UK military in recent years. This article summarises the results of the various studies and offers possible explanations for differences in findings between the UK and other allied nations. Post-traumatic stress disorder (PTSD) rates are perhaps surprisingly low amongst British forces, with prevalence rates of around 4% in personnel who have deployed, rising to 6% in combat troops, despite the high tempo of operations in recent years. The rates in personnel currently on operations are consistently lower than these. Explanations for the lower PTSD prevalence in British troops include variations in combat exposures, demographic differences, higher leader to enlisted soldier ratios, shorter operational tour lengths and differences in access to long-term health care between countries. Delayed-onset PTSD was recently found to be more common than previously supposed, accounting for nearly half of all PTSD cases; however, many of these had sub-syndromal PTSD predating the onset of the full disorder. Rates of common mental health disorders in UK troops are similar or higher to those of the general population, and overall operational deployments are not associated with an increase in mental health problems in UK regular forces. However, there does appear to be a correlation between both deployment and increased alcohol misuse and post-deployment violence in combat troops. Unlike for regular forces, there is an overall association between deployment and mental health problems in Reservists. There have been growing concerns regarding mild traumatic brain injury, though this appears to be low in British troops with an overall prevalence of 4.4% in comparison with 15% in the US military. The current strategies for detection and treatment of mental health problems in British forces are also described. The stance of the UK military is that psychological welfare of troops is primarily a chain of command responsibility, aided by medical advice when necessary, and to this end uses third location decompression, stress briefings, and Trauma Risk Management approaches. Outpatient treatment is provided by Field Mental Health Teams and military Departments of Community Mental Health, whilst inpatient care is given in specific NHS hospitals. PMID:25206948

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).

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.

Purpose To determine whether a single 51-minute exposure to acoustic noise during 3-T multisequence magnetic resonance (MR) neuroimaging could affect the hearing threshold of healthy adults with earplugs and sponge mats as hearing protection. Materials and Methods With earplugs and motion-refraining sponge mats as hearing protection, 26 healthy young adults underwent 3-T MR neuroimaging imaging that included T1-weighted three-dimensional gradient-echo sequence, T2-weighted fast spin-echo sequence, diffusion-tensor imaging, diffusion-kurtosis imaging, T2*-weighted three-dimensional multiecho gradient-echo sequence, and blood oxygen level-dependent imaging. Automated auditory brainstem response (ABR) was used to measure the hearing thresholds within 24 hours before, within 20 minutes after, and 25 days after the MR examination. One-way repeated-measure analysis of variance with Bonferroni adjustment was used to compare automated ABR results among the three tests and partial η 2 (η p 2 ) was reported as a measure of effect size. Results Automated ABR results showed significantly increased mean threshold shift of 5.0 dB ± 8.1 (standard deviation) (left ear: 4.8 dB ± 9.2 [95% confidence interval: 1.09, 8.53], η p 2 = 0.221, P = .013; right ear: 5.2 dB ± 6.9 [95% confidence interval: 2.36, 8.02], η p 2 = 0.364, P = .001) immediately after the MR examination compared with the baseline study. This shift is below the temporary threshold shift of 40-50 dB that is associated with cochlea nerve changes. Automated ABR obtained at day 25 after MR imaging showed no significant differences from baseline (left ear: -2.3 dB ± 8.6 [95% confidence interval: -5.79, 1.78], η p 2 = 0.069, P = .185; right ear: 0.4 dB ± 7.3 [95% confidence interval: -3.35, 2.58], η p 2 = 0.003, P = .791). Conclusion A 3-T MR neuroimaging examination with the acoustic noise at equivalent sound pressure level of 103.5-111.3 dBA lasting 51 minutes can cause temporary hearing threshold shift in healthy volunteers with hearing protection. © RSNA, 2017.

While bubble continuous positive airway pressure (bCPAP) is commonly used in low- and middle-income countries (LMIC) to support neonates with respiratory distress, there are limited non-invasive support options for non-neonatal children. To demonstrate safety of a new device designed to support children during respiratory distress in LMIC. A paediatric bCPAP device was designed called SEAL-bCPAP (Simplified Ear-plug Adapted-bCPAP). SEAL-bCPAP is constructed from inexpensive, easily obtainable materials. The nasal prong interface was modified from previously described neonatal bCPAP set-ups using commercial ear-plug material to improve nasal seal. A prospective interventional study was conducted to evaluate safety in children with respiratory distress treated with SEAL-bCPAP. Patients aged 30 days to 5 years presenting to a hospital in northern Uganda from July 2015 to June 2016 were screened. Those with moderate-severe respiratory distress and/or hypoxia despite nasal cannula oxygen were eligible for study. Enrolled patients were supported with SEAL-bCPAP until respiratory improvement or death. Complications attributable to SEAL-bCPAP were recorded. Clinical outcomes were compared with historical control pre-trial data. Eighty-three of 87 enrolled patients were included in the final analysis. No patients had significant SEAL-bCPAP complications. Five patients had mild complications which resolved (four with nasal irritation and one with abdominal distention). Trial patients had significant (p < 0.0001) improvement in their TAL score, respiratory rate and O 2 sat after 2 h of SEAL-bCPAP. Fifty-two of 64 patients (62.7%) with severe illness at Time1 did not have severe illness at Time2 (after 2 h of SEAL-bCPAP) (p < 0.0001). Unadjusted mortality rates were 12.2% (6/49) and 9.6% (8/83), respectively, for pre-trial (historical control) and trial patients (p = 0.64); the study was not powered to show efficacy. The SEAL-bCPAP device is safe for treatment of respiratory distress in non-neonatal children in LMIC. There is a trend toward decreased mortality that should be evaluated with adequately powered clinical trials.

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
Occupational risk factors for ill health in Gulf veterans of the United Kingdom

OBJECTIVES—To study the association between occupational factors specific to the Armed Forces (rank, functional roles, Service, regular or reservist status and deployment factors) and symptomatic health problems in Gulf veterans, after sociodemographic and lifestyle factors have been accounted for. DESIGN—A postal cross sectional survey of randomly selected UK Gulf veterans was conducted six to seven years after the Gulf conflict. Physical ill health was measured using the Fatigue Questionnaire and a measure of the Centers for Disease Control and Prevention (CDC) multi-symptom syndrome. Psychological ill health was measured using the General Health Questionnaire and a post-traumatic stress measure. SETTING—Population of servicemen who were serving in the UK Armed Forces during the Gulf conflict between 1 September 1990 and 30 June 1991. PARTICIPANTS—3297 Gulf veterans. MAIN RESULTS—In multivariate logistic regression, there was an inverse relation between higher rank and psychological and physical ill health (test of trend: General Health Questionnaire, p=0.004 ; post-traumatic stress, p=0.002; fatigue, p=0.015; CDC case, p=0.002). Having left the Armed Forces was associated with a two to three times increase in reporting ill health. Of the deployment factors, there was a weak association between being deployed as an individual reinforcement in a combat role and post-traumatic stress but there was no association between receiving pre-deployment training or post-deployment leave and ill health. Marital status and smoking were associated with psychological and physical ill health. CONCLUSIONS—Rank was the main occupational factor associated with both psychological and physical ill health in Gulf veterans. This may parallel the associations between socioeconomic status and morbidity in civilian populations. Ill health seems to be greater in those who return to civilian life. Sociodemographic factors also seem to be important in ill health in Gulf veterans. Keywords: military; Gulf veterans; rank PMID:11027197

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 .

Combat Experience and Mental Health in the Israel National Health Survey.
Lubin, Gadi; Barash, Igor; Levinson, Daphna

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.

Few studies demonstrate how the index trauma may influence subsequent post-traumatic stress disorder (PTSD) symptoms, especially among soldiers. There is still no consensus on specific trauma types and their corresponding PTSD symptom profiles. Furthermore, varied PTSD symptom manifestations that may yield to PTSD trauma subtypes are yet to be known. Importantly, the significance of the military culture's possible influence on soldiers' PTSD has also been underexplored. And the dominant PTSD construct may possibly be unable to capture the essential aspects of the military context in understanding combat-related PTSD. Hence, this study aims to reach an understanding into how index trauma and military culture may possibly shape participants' PTSD expressions. Case study design was used, wherein multiple sources of data-such as PTSD assessments, and interviews with the participants and key informants-enabled data triangulation. The three case reports are the outcomes of the corroboration of evidences that reveal an enriched and holistic understanding of the phenomenon under study. The Ethics Review Board Committee of the Armed Forces of the Philippines Medical Center approved the study. The participants were three Filipino active duty combat soldiers. Although all participants had similar index traumas, their PTSD symptom expressions are unique from one another, in that they differ in terms of their most incapacitating PTSD symptoms and other symptoms that have been potentially shaped by military culture. Their most incapacitating symptoms: hypervigilance (case 1), negative belief in oneself and negative emotions (case 2), prolonged distress, and marked physiological reactions to trauma-related cues (case 3), may be understood in the light of how they personally experienced different circumstances of their index traumas. The way participants have anchored specific components of their sworn soldier's creed (i.e., not leaving a fallen comrade) into some of their PTSD symptoms (i.e., feeling guilty for the comrade's death) may be understood in the light of their military culture and how they were personally traumatized by the details of their index traumas. The participants' index trauma and military culture potentially shaped their PTSD symptom expressions that were distinct from one another. The details of the index trauma, including the level of exposure and proximity; and the salience of military culture, such as the soldier's creed, are important elements into understanding how participants experience their PTSD. Limitations of the study include findings that do not give causal interpretations, use of self-report measures, retrospective accounts from interviews, and participants who are all Filipino active soldiers and enlisted army military personnel. Nevertheless, the study provides an enriched and holistic understanding of personal experiences of soldiers with combat-related PTSD. The findings may inform tailored treatments to soldiers whose experiences may be similar to the settings and concepts discovered in the study. Possible clinical and treatment implications were provided in the study. Future researchers may explore on: possible existence of PTSD subtypes within combat-related PTSD category, other facets of military culture that may mitigate or influence PTSD symptoms, and potential roles of index trauma and military culture using national representative samples.

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

There is an increasing understanding that Natural Killer (NK) cells not only exhibit direct activity against bacteria, but also exert indirect antibacterial activity through interaction with other immune cells via cytokines and interferons. Areas covered: This review seeks to give a global overview of in vitro and in vivo data how NK cells interact with bacteria. In this regard, the review describes how NK cells directly damage and kill bacteria by soluble factors such as perforin, the impact of NK cells on other arms of the immune system, as well as how bacteria may inhibit NK cell activities. Expert commentary: A better characterization of the antibacterial effects of NK cells is urgently needed. With a better understanding of the interaction of NK cells and bacteria, NK cells may become a promising tool to prevent or to combat bacterial infections, e.g. by adoptively transferring NK cells to immunocompromised patients.
Insects as weapons of war, terror, and torture.
Lockwood, Jeffrey A
2012-01-01
For thousands of years insects have been incorporated into human conflict, with the goals of inflicting pain, destroying food, and transmitting pathogens. Early methods used insects as "found" weapons, functioning as tactical arms (e.g., hurled nests) or in strategic habitats (e.g., mosquito-infested swamps). In the twentieth century the relationship between insects and disease was exploited; vectors were mass-produced to efficiently deliver pathogens to an enemy. The two most sophisticated programs were those of the Japanese in World War II with plague-infected fleas and cholera-coated flies and of the Americans during the Cold War with yellow fever-infected mosquitoes. With continued advances, defenses in the form of insecticides and vaccines meant that insects were no longer considered as battlefield weapons. However, in recent times sociopolitical changes have put insects back into the realm of human conflict through asymmetrical conflicts pitting combatants from nonindustrialized regions against forces from militarily and economically superior nations.

[Rehabilitation of war disabled people in the tropics: example from Colombia].
Lagauche, D
2011-12-01
The purpose of this report is to describe collaboration between the health services of the Colombian and French armed forces. Colombia is a democratic country that has been undergoing a long period of insurrection resulting in a significant number of deaths and injuries. Permanent functional disabilities have taken high toll at both the individual and community level. Due to the use of landmines, civilians pay a heavier price than military personnel. In Columbia, a country of eternal snows and rain forests, disabilities are often compounded by concurrent diseases such as malaria or leishmaniasis. Otherwise, rehabilitation of soldiers wounded during a combat is fundamentally the same in tropical zones and Europe. Management of wounded servicemen takes place in teaching hospital where therapy is carried out at the same time as training in mine clearance. Reinsertion begins with job apprenticeship in conjunction with psychological support and prosthetic training. Current focus is on developing disability rights legislation modeled on the 2005 French law.
Developing UGVs for the FCS program

The FCS Operational Requirements Document (ORD) identifies unmanned systems as a key component of the FCS Unit of Action. FCS unmanned systems include Unmanned Aerial Vehicles (UAV), Unmanned Ground Vehicles (UGV), Unattended Ground Sensors (UGS) and Unattended Munitions (UM). Unmanned systems are intended to enhance the Unit of Action across the full range of operations when integrated with manned platforms. Unmanned systems will provide the commander with tools to gather battlespace information while significantly reducing overall soldier risk. Unmanned systems will be used in some cases to augment or replace human intervention to perform many of the dirty, dull and dangerous missions presently performed by soldiers and to serve as a combat multiplier for mission performance, force protection and survivability. This paper focuses on the application of UGVs within the FCS Unit of Action. There are three different UGVs planned to support the FCS Unit of Action; the Soldier Unmanned Ground Vehicle (SUGV); The Multi-role Utility Logistics Equipment (MULE) platform; and the Armed Robotic Vehicle (ARV).

In the modern world of rapidly rising prices of new military hardware, the importance of Simulation Based Acquisition (SBA) is hard to overestimate. With SAB, DOD would be able to test, develop CONOPS for, debug, and evaluate new conceptual military equipment before actually building the expensive hardware. However, only recently powerful tools for real SBA have been developed. Linguistic Geometry (LG) permits full-scale modeling and evaluation of new military technologies, combinations of hardware systems and concepts of their application. Using LG tools, the analysts can create a gaming environment populated with the Blue forces armed with the new conceptual hardware as well as with appropriate existing weapons and equipment. This environment will also contain the intelligent enemy with appropriate weaponry and, if desired, with a conceptual counters to the new Blue weapons. Within such LG gaming environment, the analyst can run various what-ifs with the LG tools providing the simulated combatants with strategies and tactics solving their goals with minimal resources spent.

Objective To examine the factors which facilitate UK military personnel with post-traumatic stress disorder (PTSD) to engage in help-seeking behaviours. Methods The study recruited active service personnel who were attending mental health services, employed a qualitative design, used semi-structured interview schedules to collect data, and explored these data using interpretative phenomenological analysis (IPA). Results Five themes emerged about how participants were able to access help; having to reach a crisis point before accepting the need for help, overcoming feelings of shame, the importance of having an internal locus of control, finding a psychological explanation for their symptoms and having strong social support. Conclusions This study reported that for military personnel who accessed mental health services, there were a number of factors that supported them to do so. In particular, factors that combated internal stigma, such as being supported to develop an internal locus of control, appeared to be critical in supporting military personnel to engage in help-seeking behaviour.

A 62-year-old man presented with left middle cerebral artery stroke. 1 h postadministration of tissue plasminogen activator, he received a total of 4 mg of haloperidol for combativeness. He developed partial complex status epilepticus, requiring benzodiazepines, phenytoin, propofol and intubation. 5 h later, he developed recurrent stereotyped tonic movements involving arching of the back, extension of the arms and contraction of opposing muscle groups. Repeat CT scan of the head showed evolving insular infarct. Differential diagnoses for these movements included tonic/clonic seizures, extensor (decerebrate) posturing from haemorrhagic conversion, neuroleptic malignant syndrome, or dystonic reaction. Given the lack of response to antiseizure medications, the recent administration of haloperidol, and the prompt resolution of movements following diphenhydramine administration, an acute dystonic reaction was considered. This atypical case of a critically ill patient with stroke highlights the fact that these patients may have multiple abnormal movements requiring careful analysis to guide diagnosis-specific management. 2015 BMJ Publishing Group Ltd.
A Study of the Attraction Forces of Lunar Dust Simulant

Bradley, Robert Kelley; Jeevarajan, Antony; Thomas, Valor
2007-01-01
In previous manned lunar missions little work was done on countermeasures to combat the spread of lunar dust onto equipment and into the habitat because the astronauts were not scheduled to stay on the lunar surface for extended periods of time. However, as NASA prepares to return to the moon for longer durations than before developing materials that can help in the fight against lunar dust is important. The purpose of this project is to examine the attraction forces between lunar dust and various materials in an effort to discover materials which have a low affinity for lunar dust. The adhesion forces present between individual grains of dust and various materials were analyzed using an atomic force microscope (AFM). The AFM probes were calibrated by the added-mass technique to find the spring constant of the cantilever. The probes were modified by attaching a particle of lunar dust stimulant to the cantilever arm. The adhesion force between the dust particle and various materials were determined by analysis of AFM force spectra.
The stratification of military service and combat exposure, 1934–1994*
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

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.

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 experience during Operation Enduring Freedom.

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.

In comparison to other traumatic events, the impact of a childhood during war on resilience later in life has been seldom examined. The aim of this study was therefore to examine the long term outcomes of post-traumatic responses and resilience of a sample of adult Indigenous Quechua women, who were girls or adolescents during the Peruvian armed conflict (1980-1995). The study instruments (Harvard trauma questionnaire part I and IV; Connor-Davidson resilience scale; life stress questionnaire) were translated to Quechua and cross-culturally validated. A cross sectional survey design was used in 2010 to collect data from a convenience sample of 75 participants (25-45 years old) in Ayacucho, Peru, the region most affected by the conflict. Data was examined using hierarchical regression analyses. Participants reported extreme exposure to violence (e.g., sexual violence, torture, combat, death of family members, and forced displacement) during the armed conflict, but surprisingly, only 5.3% reported a current level of symptoms that may indicate a possible post-traumatic stress disorder (PTSD). Resilience scores and number of years exposed to conflict as a child were not associated with PTSD symptoms; instead only the degree of exposure to violence, and current level of stress contributed to the variance of PTSD-related symptoms. Conversely, resilience and current stress contributed to the variance of trauma symptoms when measured by local idioms of distress. Findings should be interpreted with caution, due to limitations in the content validity of instruments, risk of inaccurate recall, use of individual explanations of distress (such as PTSD) for collective experiences of violence, use of non-indigenous frameworks to examine Indigenous resilience, and other methodological concerns. The study however highlights the high degree of traumatic exposure of these former war children. While the prevalence of potential PTSD was astonishingly low in this sample, a number of women still suffer from significant distress two decades after the traumatic events. Therefore, post-conflict interventions should renew efforts to foster the resilience of marginalized populations disproportionately targeted by violence and advocate for enhanced protection of women and children in current armed conflicts.

Bridge, CA, Sparks, SA, McNaughton, LR, Close, GL, Hausen, M, Gurgel, J, and Drust, B. 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.

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.
C/sup 3/ and combat simulation - a survey
DOE Office of Scientific and Technical Information (OSTI.GOV)
Erickson, S.A. Jr.
1983-01-04
This article looks at the overlap between C/sup 3/ and combat simulation, from the point of view of the developer of combat simulations and models. In this context, there are two different questions. The first is: How and to what extent should specific models of the C/sup 3/ processes be incorporated in simulations of combat. Here the key point is the assessment of impact. In which types or levels of combat does C/sup 3/ play a role sufficiently intricate and closely coupled with combat performance that it would significantly affect combat results. Conversely, when is C/sup 3/ a known factormore » or modifier which can be simply accommodated without a specific detailed model being made for it. The second question is the inverse one. In the development of future C/sup 3/ systems, what rule should combat simulation play. Obviously, simulation of the operation of the hardware, software and other parts of the C/sup 3/ system would be useful in its design and specification, but this is not combat simulation. When is it necessary to encase the C/sup 3/ simulation model in a combat model which has enough detail to be considered a simulation itself. How should this outer combat model be scoped out as to the components needed. In order to build a background for answering these questions a two-pronged approach will be taken. First a framework for C/sup 3/ modeling will be developed, in which the various types of modeling which can be done to include or encase C/sup 3/ in a combat model are organized. This framework will hopefully be useful in describing the particular assumptions made in specific models in terms of what could be done in a more general way. Then a few specific models will be described, concentrating on the C/sup 3/ portion of the simulations, or what could be interpreted as the C/sup 3/ assumptions.« less

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.
LG tools for asymmetric wargaming

Asymmetric operations represent conflict where one of the sides would apply military power to influence the political and civil environment, to facilitate diplomacy, and to interrupt specified illegal activities. This is a special type of conflict where the participants do not initiate full-scale war. Instead, the sides may be engaged in a limited open conflict or one or several sides may covertly engage another side using unconventional or less conventional methods of engagement. They may include peace operations, combating terrorism, counterdrug operations, arms control, support of insurgencies or counterinsurgencies, show of force. An asymmetric conflict can be represented as several concurrent interlinked games of various kinds: military, transportation, economic, political, etc. Thus, various actions of peace violators, terrorists, drug traffickers, etc., can be expressed via moves in different interlinked games. LG tools allow us to fully capture the specificity of asymmetric conflicts employing the major LG concept of hypergame. Hypergame allows modeling concurrent interlinked processes taking place in geographically remote locations at different levels of resolution and time scale. For example, it allows us to model an antiterrorist operation taking place simultaneously in a number of countries around the globe and involving wide range of entities from individuals to combat units to governments. Additionally, LG allows us to model all sides of the conflict at their level of sophistication. Intelligent stakeholders are represented by means of LG generated intelligent strategies. TO generate those strategies, in addition to its own mathematical intelligence, the LG algorithm may incorporate the intelligence of the top-level experts in the respective problem domains. LG models the individual differences between intelligent stakeholders. The LG tools make it possible to incorporate most of the known traits of a stakeholder, i.e., real personalities involved in the conflict with their specific individual style.

The aim of this work is to identify the main weapons causing eye injuries during the campaigns of the Senegalese army in the south of the country, as well as the prognosis of these traumas. This study is retrospective and concerns soldiers wounded by the weapons of war during the exercise of their mission within the Senegalese armed forces of 1991 in 2005. They are mainly soldiers affected in the south of the country during a war, clashes with the rebels or in Guinea-Bissau during operation Gabou in 1998. And they were evacuated to the ophthalmology department of the Principal Hospital in Dakar, which is a level 3. Thirty-seven military all male, with an average age of 30.5 years. Forty-six eyes including 9 bilateral cases. The trauma agent is a burst of RPG7 shells in 62% of cases, mine explosion in 13.5%, offensive grenade 10.8%, assault rifle 5.7% and flame lance-roquette anti-char (LRAC) accounts for 8%. We noted a phthisis of the globe for 14 eyes (30.43%) and for 15 eyes (32.60%) a functional loss of the affected globe. Inability to fight was decided by 29 wounded soldiers (78.37% of the cases), sedentary employment in 27 cases (72.97%) and 10 cases (27.03%) of reformed soldiers. In the conflict in southern Senegal, the RPG7 shell burst causes 62% of eye injuries. This RPG7 shell called "rebel weapon" is frequently used in conflicts in Africa. The prognosis of trauma with these types of weapons is severe. The combat goggles systematically integrated in the equipment of the Senegalese combatant, would be an invaluable contribution on the prevention of the traumatisms of the eye.

Temporal indiscriminateness: the case of cluster bombs.
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.
Study on combat effectiveness of air defense missile weapon system based on queuing theory

Queuing Theory is a method to analyze the combat effectiveness of air defense missile weapon system. The model of service probability based on the queuing theory was constructed, and applied to analyzing the combat effectiveness of "Sidewinder" and "Tor-M1" air defense missile weapon system. Finally aimed at different targets densities, the combat effectiveness of different combat units of two types' defense missile weapon system is calculated. This method can be used to analyze the usefulness of air defense missile weapon system.
