    The present article deals with one of the alternative forms of energy - sea wave energy potential in the Latvian Exclusice Economic Zone (EEZ). Results have been achieved using a new method - VEVPP. Calculations have been performed using the data on wave parameters over the past five years (2010-2014). We have also considered wave energy potential in the Gulf of Riga. The conclusions have been drawn on the recommended methodology for the sea wave potential and power calculations for wave-power plant pre-design stage.

    The amount of training days lost to injury during military training has highlighted the need to identify a screening tool to predict injury. One hundred and fifty-eight female soldiers from the Combat Fitness Instructor Course (CFIC) of the Israel Defense Forces volunteered to participate in this study. All soldiers were free of orthopedic and neurologic conditions for at least one month before the study. All participants performed a battery of measurements during the first week of the course. Measures included anthropometric, functional movement screen (FMS), power performances (counter movement jump [CMJ], drop jump, single leg triple hop jump [SLTH], 10-m sprint) and a 2K run. Injury data was collected throughout the 3 month course. Median tests were used to compare between injured/non-injured soldiers. Chi-square and/or logistic regression analysis was used to examine the association between various predictors and injury. Percent body fat [%BF] was higher (p = 0.04), distance for SLTH was less for both left and right legs (p = 0.029, p = 0.047 respectively) and 2K run was slower (p =0.044) in injured compared to non-injured soldiers. No differences between groups were noted in total FMS score, however more zero scores in one or more movement pattern were found in the injured group (51.35 % vs. 30.5% p=0.0293). Only %BF, 2K run and SLTH distance were significant predictors of injury (p = 0.05, p = 0.02, p =0.016 respectively). The results of this study indicated that the FMS total score is not a predictor of injury in female soldiers in a CFIC. We found that %BF, SLTH, 2K run time, 10 meter sprint time and zero scores differentiated between injured and non-injured soldiers. In addition, %BF, 2K run and SLTH were each found to be separate predictors of injury. Further research is needed to determine threshold scores that predict injury. Key points A total of 145 injuries were reported during the three month Combat Fitness Instructor Course in a female soldiers

  6. Homogeneity of Latvian temperature and precipitation series

    During previous years and decades the homogenization of Latvian monthly temperature and precipitation data series was based on the direct homogenization methods which relayed on metadata and studies of the effects of specific changes in time of observation as well as methods of observation. However, the method is not effective for temperature and precipitation data series shifts detection caused by measurement's place relocation or environmental changes. The both climatological temperature and precipitation records are significantly affected by a number of non-climatological factors (station moves, changes in instrumentation; introduction of different observing practices like a different observing time or introduction of wetting corrections for precipitation, changes in the local urban environment). If these non-homogeneities are not accounted for properly, that makes the data unrepresentative to be used for analyses of climate state, variations and changes. Monthly and daily Latvian station series (1950-2008) of surface air temperature and precipitation are statistically tested with respect to homogeneity. Two homogeneity tests are applied to evaluate monthly series. The multiple analyses of series for homogenization MASHv3.02 has been applied to 23 Latvian mean, maximum and minimum daily and monthly data series and daily and monthly precipitation series. The standard normal homogeneity tests (SNHT) has been applied to monthly mean temperature and precipitation series. During the tested period the station network is dense enough for efficient homogeneity testing. It has been found that all the time series contain the homogeneity breaks at least during one of the month. For some stations the multiple breaks were found. For mean temperature time series the 80 % of the breaks are generally less than ±0.20C. The largest detected homogeneity breaks in the mean monthly temperatures are up to ±1.00C, in mean monthly maximum temperature are up to ±1.30C and for mean

  7. Steps towards improvement of Latvian geoid model

    The high precision geoid model is essential for the normal height determination when the GNSS positioning methods are used. In Latvia for more than 10 years gravimetric geoid model LV'98 is broadely used by surveyors and scientists. The computation of this model was performed using GRAVSOFT software using gravimetric measurements, digitised gravimetric data and satellite altimetry data over Baltic sea, the estimated accuracy of LV'98 geoid model is 6-8cm. (J. Kaminskis, 2010) However, the accuracy of Latvian geoid model should be improved. In order to aacomplish this task, the evaluation of several methods and test computations have been made. KTH method was developed at the Royal Institute of Technology (KTH) in Stockholm. This method utilizes the least-squares modification of the Stokes integral for the biased, unbiased, and optimum stochastic solutions. The modified Bruns-Stokes integral combines the regional terrestrial gravity data with a global geopotential model (GGM) (R. Kiamehr, 2006). DFHRS (Digital Finite-Element Height Reference Surface) method has been developed at the Karlsruhe University of Applied Sciences, Faculty of Geomatics (R. Jäger, 1999). In the DFHRS concept the area is divided into smaller finite elements - meshes. The height reference surface N in each mesh is calculated by a polynomial in term of (x,y) coordinates. Each group of meshes form a patch, which are related to a set of individual parameters, which are introduced by the datum parametrizations. As an input data the European Gravimetric Geoid Model 1997 (EGG97) and 102 GNSS/levelling points were used. In order to improve the Latvian geoid model quality and accuracy the development of mobile digital zenith telescope for determination of vertical deflections with 0.1" expected accuracy is commenced at University of Latvia, Institute of Geodesy and Geoinformation. The project was started in 2010, the goal of it is to design a portable, cheap and robust instrument, using industrially

    1998-08-01

    This paper addresses sensor fusion and its applications in emerging Soldier Systems integration and the unique challenges associated with the human platform. Technology that,provides the highest operational payoff in a lightweight warrior system must not only have enhanced capabilities, but have low power components resulting in order of magnitude reductions coupled with significant cost reductions. These reductions in power and cost will be achieved through partnership with industry and leveraging of commercial state of the art advancements in microelectronics and power sources. As new generation of full solution fire control systems (to include temperature, wind and range sensors) and target acquisition systems will accompany a new generation of individual combat weapons and upgrade existing weapon systems. Advanced lightweight thermal, IR, laser and video senors will be used for surveillance, target acquisition, imaging and combat identification applications. Multifunctional sensors will provide embedded training features in combat configurations allowing the soldier to 'train as he fights' without the traditional cost and weight penalties associated with separate systems. Personal status monitors (detecting pulse, respiration rate, muscle fatigue, core temperature, etc.) will provide commanders and highest echelons instantaneous medical data. Seamless integration of GPS and dead reckoning (compass and pedometer) and/or inertial sensors will aid navigation and increase position accuracy. Improved sensors and processing capability will provide earlier detection of battlefield hazards such as mines, enemy lasers and NBC (nuclear, biological, chemical) agents. Via the digitized network the situational awareness database will automatically be updated with weapon, medical, position and battlefield hazard data. Soldier Systems Sensor Fusion will ultimately establish each individual soldier as an individual sensor on the battlefield.

    2011-05-01

    The construction and validation of soldier combat models requires data on the conspicuity of camouflaged targets in the field, and human targets in particular. So far, this data is lacking. Also, it si currently unknown to what degree luminance contrast and motion contribute to target conspicuity. These data are needed to enable the validation and further development of human visual search performance modules in soldier combat models like SCOPE or IWARS. In this study we measured the conspicuity of a person wearing a Dutch army camouflage uniform, while he was either standing still, walking or running along a forest in the background, both for viewing with the naked eye (NE) and for viewing dynamic thermal scene recordings (IR). We varied the viewing distance (80m and 230 m), the camouflage pattern (woodland and desert), the type of background (pine-tree and deciduous forest), and season (summer and winter), The IR (thermal) conspicuity of the person was much larger than his NE (visual) conspicuity. In both cases the effects of movement were large and saturated as a function of retinal target speed. For NE, we find large effects of shading that can not explained by local luminance contrast variations. Also for NE, conspicuity was reduced in winter, probably as a result of an increase in scene clutter. The results suggest that conspicuity is not only a function of retinal target motion and global luminance contrast, but also depends on the amount of clutter in the scene.

    The differentiation of workers into morphological subcastes (e.g., soldiers) represents an important evolutionary transition and is thought to improve division of labor in social insects. Soldiers occur in many ant and termite species, where they make up a small proportion of the workforce. A common assumption of worker caste evolution is that soldiers are behavioral specialists. Here, we report the first test of the "rare specialist" hypothesis in a eusocial bee. Colonies of the stingless bee Tetragonisca angustula are defended by a small group of morphologically differentiated soldiers. Contrary to the rare specialist hypothesis, we found that soldiers worked more (+34%-41%) and performed a greater variety of tasks (+23%-34%) than other workers, particularly early in life. Our results suggest a "rare elite" function of soldiers in T. angustula, that is, that they perform a disproportionately large amount of the work. Division of labor was based on a combination of temporal and physical castes, but soldiers transitioned faster from one task to the next. We discuss why the rare specialist assumption might not hold in species with a moderate degree of worker differentiation.

    Overseas deployments place military personnel at risk for tropical diseases not typically observed on the U.S. mainland. This case describes the first reported case of brucellosis returning from Operation Enduring Freedom and Operation Iraqi Freedom. A 31-year-old infantry soldier complained of a 6-week history of headaches, relapsing fever, and constitutional symptoms since returning from Iraq. This soldier was determined to have the only reported case of brucellosis, but was one of many soldiers at risk from eating unpasteurized cheese on the local economy. Although malaria and leishmaniasis continue to be the most common deployment-related illnesses, brucellosis must also be considered in the differential of any redeployed soldier with headache, fever, and body aches. Public health as well as command elements must reinforce their role in preventing exposure to this pathogen. PMID:17521107

    The Gulf of Riga, river Daugava and several interconnected lakes around the City of Riga, Latvia, form adynamic brackish-freshwater system favouring occurrence of toxic cyanobacteria. We examined bioaccumulation of microcystins and nodularin-R in aquatic organisms in Latvian lakes, the Gulf of Riga and west coast of open Baltic Sea in 2002-2007. The freshwater unionids accumulated toxins efficiently,followed by snails. In contrast, Dreissena polymorpha and most lake fishes (except roach) accumulated much less hepatotoxins. Significant nodularin-R concentrations were detected also in marine clams and flounders. No transfer of nodularin-R and microcystins between lake and brackish water systems took place. Lake mussels can transfer hepatotoxins to higher organisms, and also effectively remove toxins from the water column. Obvious health risks to aquatic organisms and humans are discussed.

    2008-04-01

    The Soldier Universal Robot Controller (SURC) is a modular OCU designed for simultaneous control of heterogeneous unmanned vehicles. It has a well defined, published API., defined using XML schemas, that allows other potential users of the system to develop their own modules for rapid integration with SURC. The SURC architecture is broken down into three layers: User Interface, Core Functions, and Transport. The User Interface layer is the front end module which provides the human computer interface for user control of robots. The Core layer is further divided into the following modules: Capabilities, Tactical, Mobility, and World Model. The Capabilities module keeps track of the known robots and provides a list of specifications and services. The Mobility module provides path planning via D*, while the Tactical module provides higher level mission planning (multi-agent/multi-mission) capabilities for collaborative operations. The World Model module is a relational database which stores world model objects. Finally, a Transport module provides translation from the SURC architecture to the robot specific messaging protocols (such as JAUS). This allows fast integration of new robot protocols into an existing SURC implementation to enable a new system to rapidly leverage existing SURC capabilities. The communication between different modules within the SURC architecture is done via XML. This gives developers and users the flexibility to extend existing messages without breaking backwards compatibility. The modularity of SURC offers users and developers alike the capability to create custom modules and plug them into place, as long as they follow the pre defined messaging API for that module.

    Sick and injured children, like combatants wounded by shot and shell in war, are disproportionately represented in the tallies of both man-made and national disasters. Paediatricians have a particularly proud heritage of military service, a nexus dating in Australia from the early 19th century. This paper traces this link between service to children in peacetime and the care of servicemen, women and children in times of war and disaster. The extraordinary record of Australian 'paediatric' doctors who also served in the Gallipoli Campaign (1915) is documented as an illustration of this duality. Paediatricians who serve in the Defence Reserves and in civilian non-government organisations which respond to disasters and civil wars have special credentials in their advocacy for the protection of children enmeshed in conflict or disaster. Such applies particularly to the banning of the recruitment and use of child soldiers; support for children caught up in refugee and illegal immigrant confrontations; and continued advocacy for greater international compliance with the Ottawa Convention to ban the use of anti-personnel landmines. Volunteering for such service must occur in cold 'down time', ensuring that paediatricians are trained in disaster and conflict response, when such challenges inevitably confront the paediatricians of the future.

    The Special Issue (June 2011) of the Journal of Clinical Psychology in Medical Settings titled Strengthening Our Soldiers (SOS) and Their Families: Contemporary Psychological Advances Applied to Wartime Problems revealed the following important concerns: 1) Who is at risk for psychological sequelae during and following service in the U.S. military? 2) How to deliver the best treatment for our soldiers and veterans with PTSD, Traumatic Brain Injury and Pain? 3) How to train the trainers? and 4) What are the current priorities for service delivery, research and funding? Assessment strategies and tools are provided to assist in identification of suicidal ideation and behaviors, alcohol abuse in spouses, posttraumatic stress disorders, depression, brain injuries and post-concussion syndrome, as well as positive growth experiences. Empirically validated Cognitive Processing and Prolonged Exposure treatments are described as are the empirical results already in evidence in our military populations. The innovative use of Virtual Reality and Telehealth applications is demonstrated in both army and naval settings for preparing and reducing trauma in affected soldiers. The Functional and Occupational Rehabilitation Treatment (FORT) Program and its role in returning function to injured soldiers with musculoskeletal pain and motion restrictions, while also leading to reductions of anxiety, depression and use of medical services, is described. A critique about providing service-research for children's reactions to their parent's deployments and family functioning during separation and reintegration is provided. The need for theoretical-empirical approaches to understanding pain-behavior, anxiety dysregulation as it impacts the brain function and structure is provided by experts in pain, neuropsychology, brain circuitry and anxiety management of multiple traumas.

    Through military training, soldiers' bodies are shaped and prepared for war and military-related duties. In the context these former Zimbabwean soldiers find themselves--that of desertion and 'underground life' in exile in South Africa--their military-trained bodies and military skills are their only resource. In this article, we explore the ways in which former soldiers maintain and 'reuse' their military-trained bodies in South Africa for survival, in a context of high unemployment and a violent, inner-city environment. We look at their social world and practices of soldiering--a term that refers to the specific forms of their social interaction in exile, through which they keep their memories of their military past alive. By attending to their subjectivities and the endurance of their masculine military identities and bodies, we aim to contribute to the discussion on demilitarization, which has largely focused on the failure of models of intervention to assist ex-combatants in postconflict contexts.

    Eye injuries come at a high cost to society and are avoidable. Ocular blast injuries can be primary, from the blast wave itself; secondary, from fragments carried by the blast wind; tertiary; due to structural collapse or being thrown against a fixed object; or quaternary, from burns and indirect injuries. Ballistic eye protection significantly reduces the incidence of eye injuries and should be encouraged from an early stage in Military training. Management of an injured eye requires meticulous history taking, evaluation of vision that measures the acuity and if there is a relative pupillary defect as well as careful inspection of the eyes, under anaesthetic if necessary. A lateral canthotomy with cantholysis should be performed immediately if there is a sight-threatening retrobulbar haemorrhage. Systemic antibiotics should be prescribed if there is a suspected penetrating or perforating injury. A ruptured globe should be protected by an eye shield. Primary repair of ruptured globes should be performed in a timely fashion. Secondary procedures will often be required at a later date to achieve sight preservation. A poor initial visual acuity is not a guarantee of a poor final result. The final result can be predicted after approximately 3–4 weeks. Future research in eye injuries attempts to reduce scarring and neuronal damage as well as to promote photoreceptor rescue, using post-transcriptional inhibition of cell death pathways and vaccination to promote neural recovery. Where the sight has been lost sensory substitution of a picture from a spectacle mounted video camera to the touch receptors of the tongue can be used to achieve appreciation of the outside world.

    The National Museum of Health and Medicine holds a collection of anatomical specimens from nearly 2,000 soldiers injured during the American Civil War. Originally collected as part of a study of trauma and disease during war, these specimens have been museum artifacts for over 140 years. During this time, they have been displayed and utilized in an array of interpretative strategies. They have functioned as medical specimens documenting the effects of gunshot wounds and infection to the human body, as mementos mori symbolizing the refuse of a nation divided by war, and as objects of osteological and forensic interest. The museum’s curators recently discovered four of these specimens from soldiers who the poet and essayist Walt Whitman nursed in the wartime hospitals of Washington, DC. Uniting these remains with Whitman’s words yields a new interpretation that bears witness to individual histories during a time of unprecedented conflict in American history. PMID:22741042

    Genetic diversity and inheritance of 65 microsatellite (SSR) loci were studied in a set of 37 barley varieties involved in the pedigrees of seven Latvian barley varieties: Abava, Agra, Balga, Imula, Linga, Priekulu 1 and Stendes. Cluster analysis divided all the varieties into two large groups according to their geographic distribution. Moravian, Swedish and Danish varieties clustered separately from varieties from Norway and Finland. The pattern of subgroups of both European and Latvian varieties was in accordance with their pedigree information. Graphical genotypes of microsatellite alleles of all seven barley chromosomes were determined for all the 37 varieties studied. Parental inheritance and transmission of microsatellite alleles through the generations of the pedigrees were analysed. The results confirmed the importance and informative value of microsatellite markers for genetic studies in barley and their utility for barley breeding and other applications in fundamental and applied barley genetics.

    We report herein the results of the cross-cultural adaptation and validation into the Latvian language of the parent's version of two health related quality of life instruments. The Childhood Health Assessment Questionnaire (CHAQ) is a disease specific health instrument that measures functional ability in daily living activities in children with juvenile idiopathic arthritis (JIA). The Child Health Questionnaire (CHQ) is a generic health instrument designed to capture the physical and psychosocial well-being of children independently from the underlying disease. The Latvian CHAQ CHQ were fully validated with 1 forward and 1 backward translations. A total of 141 subjects were enrolled: 80 patients with JIA (16% systemic onset, 32.5% polyarticular onset, 19% extended oligoarticular subtype, and 32.5% persistent oligoarticular subtype) and 61 healthy children. The CHAQ clinically discriminated between healthy subjects and JIA patients, with the systemic, polyarticular and extended oligoarticular subtypes having a higher degree of disability, pain, and a lower overall well-being when compared to their healthy peers. Also the CHQ clinically discriminated between healthy subjects and JIA patients, with the systemic onset, polyarticular onset and extended oligoarticular subtypes having a lower physical and psychosocial well-being when compared to their healthy peers. In conclusion the Latvian version of the CHAQ-CHQ is a reliable, and valid tool for the functional, physical and psychosocial assessment of children with JIA.

    Small ubiquitin-related modifier (SUMO4), located in IDDM5, has been identified as a potential susceptibility gene for type 1 diabetes mellitus (T1DM). The novel polymorphism M55V, causing an amino acid change in the evolutionarily conserved met55 residue has been shown to activate the nuclear factor kappaB (NF-kappaB), hence the suspected role of SUMO4 in the pathogenicity of T1DM. The M55V polymorphism has been shown to be associated with susceptibility to T1DM in Asians, but not in Caucasians. Latent autoimmune diabetes in adults (LADA) is a slowly progressive form of T1DM and SUMO4 M55V has not been studied in LADA to date. The current study aims to test whether Latvians are similar to Caucasians in susceptibility to autoimmune diabetes (T1DM and LADA), with respect to SUMO4 M55V. We studied, age- and sex-matched, Latvian T1DM patients (n = 100) and healthy controls (n = 90) and LADA patients (n = 45) and healthy controls (n = 95). SUMO4 M55V polymorphism was analyzed using polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP). The allelic frequencies of the A and G alleles were compared with HLA DR3-DR4-positive and HLA DR3-DR4-negative patients to identify any potential relation between HLA DR3-DR4 and SUMO4 M55V. We found no significant association between SUMO4 M55V and T1DM susceptibility in Latvians, the results being in concurrence with the previous studies in Caucasians of British and Canadian origin. Comparison of the A and G alleles with HLA DR3-DR4 did not result in any significant P values. No significant association was found between SUMO4 M55V and LADA. SUMO4 M55V is not associated with susceptibility to T1DM and LADA in Latvians, and Latvians exhibit similarity to other Caucasians with respect to association of SUMO4 M55V with autoimmune diabetes.

    Small ubiquitin-related modifier (SUMO4), located in IDDM5, has been identified as a potential susceptibility gene for type 1 diabetes mellitus (T1DM). The novel polymorphism M55V, causing an amino acid change in the evolutionarily conserved met55 residue has been shown to activate the nuclear factor kappaB (NF-kappaB), hence the suspected role of SUMO4 in the pathogenicity of T1DM. The M55V polymorphism has been shown to be associated with susceptibility to T1DM in Asians, but not in Caucasians. Latent autoimmune diabetes in adults (LADA) is a slowly progressive form of T1DM and SUMO4 M55V has not been studied in LADA to date.

  14. Shooting disabled soldiers: medicine and photography in World War I America.

    PubMed

    Linker, Beth

    2011-07-01

    This article challenges conventional theories about the role of medical photography in the early twentieth century. Some scholars argue that the camera intensified the Foucauldian medical gaze, reducing patients to mere pathologies. Others maintain that with the rise of the new modern hospital and its state-of-the-art technologies, the patient fell from view entirely, with apertures pointing toward streamlined operating rooms rather than the human subjects who would go under the knife. The Army Surgeon General's World War I rehabilitation journal, Carry On: A Magazine on the Reconstruction of Disabled Soldiers and Sailors, problematizes these assumptions. Hoping to persuade a skeptical public that the Army's new programs in medical rehabilitation for disabled soldiers provided the best means of veteran welfare, the editorial officials at Carry On photographed patients fully clothed, wounds hidden, engaged in everyday activities in order to give the impression that the medical sciences of the day could cure permanent disabilities. In the end, Carry On shows us that medical doctors could, and did, use photography to conceal as well as reveal the reality faced by injured soldiers. In doing so, they (like other Progressive reformers at the time) hoped to persuade the public that rehabilitation had the power to make the wounds of war disappear.

    The paper analyses the performance results of the recently developed short-term forecasting suit for the Latvian power system. The system load and wind power are forecasted using ANN and ARIMA models, respectively, and the forecasting accuracy is evaluated in terms of errors, mean absolute errors and mean absolute percentage errors. The investigation of influence of additional input variables on load forecasting errors is performed. The interplay of hourly loads and wind power forecasting errors is also evaluated for the Latvian power system with historical loads (the year 2011) and planned wind power capacities (the year 2023).

    Musculoskeletal injuries (MSIs) result in the most medical encounters, lost duty days, and permanent disability. Women are at greater risk of injury than men and physical training is the leading cause of injury. The purpose of this study was to investigate the demographic, body composition, fitness, and physical training risk factors for injuries in female Soldiers serving in garrison Army units over the past 12 months. Self-report survey was collected from 625 women. The ankle was the most frequently injured body region, 13%. Running was the activity most often associated with injury, 34%. In univariate analysis lower rank, older age, history of deployment, no unit runs, weekly frequency of personal resistance training, and history of injury were all associated with injury. In multivariate analysis rank, history of injury, weekly frequency of unit runs, and weekly frequency of personal resistance training were the best combination of predictors of injury. Running once or twice a week with the unit protected against MSIs, whereas participating in personal resistance training sessions once or twice a week increased the risk of MSIs. With more emphasis on running and resistance training, the U.S. Army could reduce injuries and save billions of dollars in training and health care costs.

    The future battlefield will require an unprecedented level of automation in which soldier-operated, autonomous, and semi-autonomous ground, air, and sea platforms along with mounted and dismounted soldiers will function as a tightly coupled team. Sophisticated robotic platforms with diverse sensor suites will be an integral part of the Objective Force, and must be able to collaborate not only amongst themselves but also with their manned partners. The Army Research Laboratory has developed a robot-based acoustic detection system that will detect and localize on an impulsive noise event, such as a sniper's weapon firing. Additionally, acoustic sensor arrays worn on a soldier's helmet or equipment can enhance his situational awareness and RSTA capabilities. The Land Warrior or Objective Force Warrior body-worn computer can detect tactically significant impulsive signatures from bullets, mortars, artillery, and missiles or spectral signatures from tanks, helicopters, UAVs, and mobile robots. Time-difference-of-arrival techniques can determine a sound's direction of arrival, while head attitude sensors can instantly determine the helmet orientation at time of capture. With precision GPS location of the soldier, along with the locations of other soldiers, robots, or unattended ground sensors that heard the same event, triangulation techniques can produce an accurate location of the target. Data from C-4 explosions and 0.50-Caliber shots shows that both helmet and robot systems can localize on the same event. This provides an awesome capability - mobile robots and soldiers working together on an ever-changing battlespace to detect the enemy and improve the survivability, mobility, and lethality of our future warriors.

Our team has chosen to structure and systematise the involvement of the families of hospitalised soldiers.A family psychotherapy consultation has also been reinforced in orderto favourthe inclusion of the families of soldiers in crisis. These two tools are complementary and have enabled us to enrich the multidisciplinary work within the unit, as well as the relationship with the patients and families confronted with a crisis.

    Epidemiologic studies on the health effects of the Chernobyl disaster have focused largely on physical health, whereas the psychological consequences have received little attention. The authors have assessed the associations of various exposure variables with mental and psychosomatic distress in a sample of 1412 Latvian liquidators drawn from the State Latvian Chernobyl Clean-up Workers Registry. The outcome was a mixed mental-psychosomatic disorder occurring during 1986 to 1995. Comparisons among subgroups of the cohort classified according to exposure type or level were based on the proportional hazards model. Length of work (> or = 28 days) in a 10-km radius from the reactor (relative risk [RR] = 1.39, 95% confidence interval [CI] 1.14-1.70), work (> 1 time) on the damaged reactor roof (RR = 1.46, 95% CI 1.02-2.09), forest work (RR = 1.41, 95% CI 1.19-1.68), fresh fruit consumption (> or = 1 time/day) (RR = 1.72, 95% CI 1.12-2.65) are risk factors for mixed mental-psychosomatic disorder. Construction of the sarcophagus (RR = 1.82, 95% CI 0.89-3.72) is also associated with this outcome, although nonsignificantly. Distinguishing stress-related from radiation-induced effects in this data set was difficult and these findings should provide a basis for later hypothesis testing in other cohorts. PMID:9467079

    The present research examines posttraumatic resilience in extremely exposed children and adolescents based on interviews with 330 former Ugandan child soldiers (age = 11-17, female = 48.5%). Despite severe trauma exposure, 27.6% showed posttraumatic resilience as indicated by the absence of posttraumatic stress disorder, depression, and clinically significant behavioral and emotional problems. Among these former child soldiers, posttraumatic resilience was associated with lower exposure to domestic violence, lower guilt cognitions, less motivation to seek revenge, better socioeconomic situation in the family, and more perceived spiritual support. Among the youth with significant psychopathology, many of them had symptoms extending beyond the criteria for posttraumatic stress disorder, in keeping with the emerging concept of developmental trauma disorder. Implications for future research, intervention, and policy are discussed.

    2000-01-01

    The aphid Pseudoregma sundanica (Van der Goot) (Homoptera: Aphididae) has two defence strategies. It is obligatorily tended by various species of ant and also produces sterile soldiers. We investigated how they allocate their investment in these two strategies. We measured the size, number of soldiers, number and species of tending ant, and number and species of predators in P. sundanica populations. We found that the level of ant tending correlated negatively with soldier investment in P. sundanica. The species of tending ant also influenced soldier investment. We excluded ants from aphid populations and recorded changes in population size and structure over four weeks. Ant exclusion led to population decline and extinction. At the same time, surviving populations showed a significant increase in soldier investment. The data demonstrate that social aphids can adjust their investment in soldiers in direct response to environmental change. PMID:11052537

    Thai soldiers who were conscripted, Royal Thai Army forces, professional Border Patrol Police, or local militia (Thai Rangers) located in any of seven provinces of Thailand were bled in April and again, four months later, in July 1989. In 1991, soldiers from five different locations in southern Thailand were bled once, in July. Serum samples were tested by indirect fluorescent antibody assay for antibody to Orientia (formerly Rickettsia) tsutsugamushi, etiologic agent of scrub typhus, with any titer > or = 1:50 considered positive. Prior to field exercises, prevalence of antibody varied significantly between different types of units, ranging between 18.6% for Thai Rangers and 6.8% for the Royal Thai Army. The April prevalence, July prevalence, and incidence varied significantly by province in 1989, with highest incidence being 14.5% in Kanchanaburi and the lowest 0% in Utraladit. The prevalence in southern Thailand in 1991 varied between 1.6% and 6.8%. The data demonstrate that O. tsutsugamushi is widely distributed in Thailand and that military activity consisting of field exercises that simulate combat conditions significantly expose soldiers to infection.

    Seventy-one deployed U.S. Army soldiers who presented for concussion care due to either blast or blunt mechanisms within 72 h of injury were assessed using the Military Acute Concussion Evaluation, the Automated Neuropsychological Assessment Metrics (ANAM), traditional neuropsychological tests, and health status questionnaires. Follow-up ANAM testing was performed 10 d after initial testing (±5 d). Twenty-one soldiers were excluded: two for poor effort and 19 who had combined blast/blunt injuries. Of the remaining 50 male participants, 34 had blast injuries and 16 had blunt injuries. There were no statistically significant differences between blast injury and blunt injury participants in demographic, physical, or psychological health factors, concussive symptoms, or automated and traditional neurocognitive testing scores within 72 h post-injury. In addition, follow-up ANAM scores up to 15 d post-injury were not significantly different (available on 21 blast-injured and 13 blunt-injured subjects). Pre-injury baseline ANAM scores were compared where available, and revealed no statistically significant differences between 22 blast injury and eight blunt injury participants. These findings suggest there are no significant differences between mechanisms of injury during both the acute and subacute periods in neurobehavioral concussion sequelae while deployed in a combat environment. The current study supports the use of sports/mechanical concussion models for early concussion management in the deployed setting and exploration of variability in potential long-term outcomes.

  12. Ventilator Technologies Sustain Critically Injured Patients

    NASA Technical Reports Server (NTRS)

    2012-01-01

    Consider this scenario: A soldier has been critically wounded in a sudden firefight in a remote region of Afghanistan. The soldier s comrades attend to him and radio for help, but the soldier needs immediate medical expertise and treatment that is currently miles away. The connection between medical support for soldiers on the battlefield and astronauts in space may not be immediately obvious. But when it comes to providing adequate critical care, NASA and the military have very similar operational challenges, says Shannon Melton of NASA contractor Wyle Integrated Science and Engineering. Melton works within Johnson Space Center s Space Medicine Division, which supports astronaut crew health before, during, and after flight. In space, we have a limited number of care providers, and those providers are not always clinicians with extensive medical training. We have limited room to provide care, limited consumables, and our environment is not like that of a hospital, she says. The Space Medicine Division s Advanced Projects Group works on combining the expertise of both clinicians and engineers to develop new capabilities that address the challenges of medical support in space, including providing care to distant patients. This field, called telemedicine, blends advanced communications practices and technologies with innovative medical devices and techniques to allow caregivers with limited or no medical experience to support a patient s needs. NASA, just by its nature, has been doing remote medicine since the beginning of the Space Program, says Melton, an engineer in the Advanced Projects Group. Since part of NASA s mandate is to transfer the results of its technological innovation for the benefit of the public, the Agency has worked with doctors and private industry to find ways to apply the benefits of space medicine on Earth. In one such case, a NASA partnership has resulted in new technologies that may improve the quality of emergency medicine for wounded

  13. Factors influencing injury severity score regarding Thai military personnel injured in mass casualty incident April 10, 2010: lessons learned from armed conflict casualties: a retrospective study

    PubMed Central

    2012-01-01

    Background Political conflicts in Bangkok, Thailand have caused mass casualties, especially the latest event April 10, 2010, in which many military personnel were injured. Most of them were transferred to Phramongkutklao Hospital, the largest military hospital in Thailand. The current study aimed to assess factors influencing Injury Severity Score (ISS) regarding Thai military personnel injured in the mass casualty incident (MCI) April 10, 2010. Methods A total of 728 injured soldiers transferred to Phramongkutklao Hospital were reviewed. Descriptive statistics was used to display characteristics of the injuries, relationship between mechanism of injury and injured body regions. Multiple logistic regressions were used to calculate the adjusted odds ratio (adjusted OR) of ISS comparing injured body region categories. Results In all, 153 subjects defined as major data category were enrolled in this study. Blast injury was the most common mechanism of injury (90.2%). These victims displayed 276 injured body regions. The most common injured body region was the extremities (48.5%). A total of 18 patients (11.7%) had an ISS revealing more than 16 points. Three victims who died were expected to die due to high Trauma and Injury Severity Score (TRISS). However, one with high TRISS survived. Factors influencing ISS were age (p = 0.04), abdomen injury (adjusted OR = 29.9; 95% CI, 5.8-153.5; P < 0.01), head & neck injury (adjusted OR = 13.8; 95% CI, 2.4-80.4; P < 0.01) and chest injury (adjusted OR = 9.9; 95% CI, 2.1-47.3; P < 0.01). Conclusions Blast injury was the most common mechanism of injury among Thai military personnel injured in the MCI April 10, 2010. Age and injured body region such as head & neck, chest and abdomen significantly influenced ISS. These factors should be investigated for effective medical treatment and preparing protective equipment to prevent such injuries in the future. PMID:22214518

    Repeated combat deployments to Iraq and Afghanistan are resulting in increased rates of posttraumatic stress disorder (PTSD) among military personnel. Although exposure therapy is an effective treatment for this disorder, some personnel do not significantly respond to treatment, possibly due to poor activation of the trauma memory or a lack of emotional engagement during therapy. In addition, some service members do not seek mental healthcare due to treatment stigma. Researchers recently developed a virtual reality (VR) Iraq to attempt to improve activation of the traumatic memory during exposure therapy and to provide a treatment approach that may be more appealing to some service members, relative to traditional face-to-face talk therapy. Initial validation of the application requires an assessment of how well it represents the experiences of previously deployed service members. This study evaluated the realism of the VR Iraq application according to the subjective evaluation of 93 U.S. Army soldiers who returned from Iraq in the last year. Those screening negative for PTSD used and evaluated a VR tactical convoy and a VR dismounted patrol in a simulated Middle Eastern city. Results indicated that 86% of soldiers rated the overall realism of the VR convoy as ranging from adequate to excellent. Eighty-two percent of soldiers reported adequate-to-excellent overall realism of the city environment. Results provide evidence that the VR Iraq presents a realistic context in which VR exposure therapy can be conducted. However, clinical trials are needed to assess the efficacy of VR exposure therapy for Iraq veterans with PTSD. PMID:19199854

    Physical Optics Corporation (POC) developed the body-worn Integrated Soldier Power and Data System (ISPDS), a configurable node for plug-in wired or wireless server/client or peer-to-peer computing with accommodations for power, sensor I/O interfaces, and energy harvesting. The enabling technology increases the efficacy of uniformed personnel and first responders and provides an option for reducing force structure associated with the need for hardware network infrastructure to enable a mobile digital communications architecture for dismounted troops. The ISPDS system addresses the DoD's need for an "intelligent" power control system in an effort to increase mission duration and maximize the first responders and warfighter's effectiveness without concern for the available energy resources (i.e., batteries). ISPDS maximizes durability and survivability, assesses influences that affect performance, and provides the network backbone and mobile node hardware. POC is producing two vest-integrated variants, one each for the U.S. Army PEO Ground Soldier and the Air Soldier, with each including state-of-the-art low-profile and robust wearable connectors, cabling, and harnesses, and an integrated low-profile power manager and conformal battery for data and power distribution. The innovative intelligent power controller (IPC), in the form of the ISPDS firmware and power sensing and control electronics, will enable ISPDS to optimize power levels both automatically and in accordance with manually set preferences. The IPC module is power dense and efficient, and adaptively provides lossless transfer of available harvested photovoltaic energy to the battery. The integrated systems were tested for suitable electrical, electromagnetic interference (EMI), and environmental performance as outlined in military standards such as MIL-STD- 810G and MIL STD-461F.

    In termites, i.e. a major group of eusocial insects, the soldier caste exhibits specific morphological characteristics and extremely high aggression against predators. Although the genomic background is identical to the other non-aggressive castes, they acquire the soldier-specific behavioral character during the course of caste differentiation. The high aggressiveness and defensive behavior is essential for colony survival, but the neurophysiological bases are completely unknown. In the present study, using the damp-wood termite Hodotermopsis sjostedti, we focused on two biogenic amines, octopamine (OA) and tyramine (TA), as candidate neuromodulators for the defensive behavior in soldiers. High-performance liquid chromatographic analysis revealed that TA levels in the brain and suboesophageal ganglion (SOG) and the OA level in brain were increased in soldiers than in pseudergates (worker caste). Immunohistochemical analysis revealed that TA/OA neurons that innervate specific areas, including the mandibular muscles, antennal nerve, central complex, suboesophageal ganglion, and thoracic and/or abdominal ganglia, were enlarged in a soldier-specific manner. Together with the results that pharmacological application of TA promoted the defensive behavior in pseudergates, these findings suggest that the increased TA/OA levels induce the higher aggressiveness and defensive behavior in termite soldiers. The projection targets of these soldier-specific enlarged TA/OA neurons may have important roles in the higher aggressiveness and defensive behavior of the termite soldiers, inducing the neuronal transition that accompanies external morphological changes.

Immunohistochemical analysis revealed that TA/OA neurons that innervate specific areas, including the mandibular muscles, antennal nerve, central complex, suboesophageal ganglion, and thoracic and/or abdominal ganglia, were enlarged in a soldier-specific manner. Together with the results that pharmacological application of TA promoted the defensive behavior in pseudergates, these findings suggest that the increased TA/OA levels induce the higher aggressiveness and defensive behavior in termite soldiers. The projection targets of these soldier-specific enlarged TA/OA neurons may have important roles in the higher aggressiveness and defensive behavior of the termite soldiers, inducing the neuronal transition that accompanies external morphological changes.

    Around the world, there are an estimated 300,000 to 500,000 children involved in armed conflict. Children can be abducted into a fighting force to fight or serve as sex slaves. Child soldiers have depression, anxiety, and posttraumatic stress symptoms; however, evidence is mixed because of methodologic limitations. Various mental health interventions have been tried, with promising results. Child and adolescent psychiatrists are uniquely trained in understanding and assisting youth to heal from such extraordinary experiences. A public health paradigm could include interventions that are based on a comprehensive assessment of interweaving developmental, biological, psychological, and sociocultural factors.

    Three extracts originating from a combination of various Latvian plant species were tested for their antibacterial activities by evaluating growth delays using a fully automated microturbidimetric method. Ten different human and bovine strains of the genera Staphylococcus and Micrococcus were used as test microorganisms. The inhibitory effect in vitro was defined as the difference between the growth rate without herbs and the growth rate in the presence of an extract. Among the tested strains, Staphylococcus aureus was found sensitive to all 3 extracts. However, extract I was the most effective in slowing the growth of all strains tested. Using appropriate tester strains it should be possible to set up a broad-range microtubidimetry assay for individual herb screening in vitro. The hemolytic effects of the individual extracts on human erythrocytes were also studied at different concentrations. Two of the herbal extracts had minimal lytic effects on eurocaryotic cells. An additional hemolysis test was conducted in the presence of coenzyme Q10 (CoQ10) as a free radical scavenger: CoQ10 had no effect on the hemolytic reaction. PMID:11111939

    Latvian insulin-dependent diabetes mellitus (IDDM) patients (n=101) and healthy controls (n=111) were analyzed for HLA-DR and DQ polymorphism. DR3-DQ2 and DR4-DQ8 were positively associated and DR15-DQ6, DR13-DQ6, DR1-DQ5 and DQ7 negatively associated with the disease. The incidence of IDDM in Latvia is very low (6.5 per 100,000) compared to Sweden (24.4 per 100,000), even though Latvia is close to Sweden. The reasons for the decreased incidence are not clear. When the negatively associated DQ were taken together in the healthy controls, more than 75% of the healthy controls were positive for one of the four negatively associated DQ molecules. The excess frequency of the negatively associated DQ molecules in the general population could explain the lower incidence of IDDM in Latvia. Association of HLA-DR and DQ genes with autoantibody markers shows DR3, but not DQ2, to be increased in GAD65 antibody-positive compared to antibody-negative patients. This association was not observed with ICA512 antibodies.

    This publication is dedicated to the 150th birth anniversary of a famous German-writing Latvian physician, historian of medicine, and anthropologist of Jewish descent Izidor Brennsohn, and to his ties with Lithuania. I. Brennsohn's works on physicians and the development of health care in Kurland, Livland, and Estland laid the foundations for the contemporary historiography of medicine in Latvia and Estonia. To a certain extent, these works could also be viewed as a digest of the sources of Lithuanian history of medicine, especially in regard to the regions on the boarder with Latvia, as well as to various personalities. However, Brennsohn's most important link with Lithuania was his doctoral thesis "On Lithuanian anthropology" ("Zur Anthropologie der Litauer"), defended at Dorpat (Tartu) University in 1883. It was one of the first works dealing with Lithuanian ethnic anthropology as a whole. Although, material of thesis could not be used for wider generalizations, still, it is one of rare and valuable 19th century sources of Lithuanian anthropology. Brennsohn's legacy deserves greater attention from people researching medical history in Lithuania. PMID:15456980

  8. Injured Athletes and the Risk of Suicide

    Research on the emotional responses of athletes to injury shows significant depression that may be profound and may last a month or more, paralleling the athlete's perceived recovery. Injured athletes cared for by athletic trainers are often between the ages of 15 to 24, the high-risk age group for suicide, which is currently a leading cause of death for young Americans. The purposes of this paper are to discuss postinjury depression, the incidence and risk factors of suicide, athletic injury as a psychosocial risk factor, the features common to suicide attempts in case studies of five injured athletes, and the motivation of athletes for sport participation. We also suggest ways in which athletic trainers can assess injured athletes for depression and risk of suicide. The five injured athletes who attempted suicide shared several common factors. All had experienced 1) considerable success before sustaining injury; 2) a serious injury requiring surgery; 3) a long, arduous rehabilitation with restriction from their preferred sport; 4) a lack of preinjury competence on return to sport; and 5) being replaced in their positions by teammates. Also, all were in the highrisk age group for suicide. As a primary care provider, the certified athletic trainer is in an ideal position to detect serious postinjury depression and to determine whether the injured athlete is at risk for suicide.

  9. Narrating the self-injured body

    Illness narratives have traditionally been used as a conceptual tool for exploring experiences of chronic illness or disease. In this paper, I suggest that Frank's typology of illness narratives (chaos, restitution and quest) also offers an illuminating approach to analysing accounts of self-injury, demonstrating the diverse ways in which self-injury is practiced, experienced and narrated. Drawing on 24 narrative interviews with 12 people who had self-injured, I focus on participants’ accounts of their self-injured bodies. The approach is phenomenological, and concerned with talk about the experience of living with and in a body that has been marked by self-injury. Thus, the act of self-injury is not the sole focus, and particular attention is paid to accounts of the bodily aftermath: scars, marks and wounds. Scars left by self-injury can be seen as communicative, and the analysis developed here demonstrates some of the various ways that these marks may be read. Attending to these diverse narratives can contribute to the provision of compassionate, non-judgemental care for patients who have self-injured. Further, highlighting the existence of different ways of narrating the self-injured body may offer an optimistic resource for people who have self-injured. PMID:24812335

    Germline mutations of the CDKN2A and CDK4 genes explain a significant proportion of familial melanoma. To date, there have been few published estimations of the prevalence of such mutations in sporadic melanoma patients. In this study, we investigated CDKN2A and CDK4 exon 2 for germline mutations in 125 consecutive cutaneous malignant melanoma patients recruited through the Latvian Oncological Center, using amplicon melting analysis and sequencing. No disease-related CDKN2A germline mutations were identified in any of the melanoma patients analysed but the previously described CDK4 mutation, Arg24His, was found in one patient with a family history of melanoma. CDKN2A polymorphisms were studied as putative low penetrance susceptibility genes. The proportion of cases with polymorphisms in this Latvian melanoma population was Ala148Thr (c.442G>A) (6%), 500 C/G (c.*29C>G) (18%), and 540 C/T (c.*69C>T) (20%); however, only the frequency of the Ala148Thr polymorphism was higher in melanoma patients than in 203 controls (6 versus 1%, P=0.03). Ala148Thr has also been reported in association with melanoma in a Polish series but not in an English series. We therefore examined the Ala148Thr carrier's haplotype in 10 Latvian and 39 Polish samples. No significant difference was seen between these populations and the predominant haplotype observed in English samples, giving no indication that the discrepancy could be explained by population differences in linkage disequilibrium. In summary, our results show that germline mutations at the CDKN2A locus are rare in sporadic melanoma in Latvia. The study does, however, provide some additional evidence for a role for the CDKN2A polymorphism Ala148Thr as a low penetrance susceptibility gene. The detected CDK4 exon 2 mutation was found in only the seventh family identified worldwide with a germline CDK4 mutation.

    A plan for the early management of the critically injured patient is described with emphasis on the priorities of management of injuries to certain organ-systems. The most important priorities are the establishment and maintenance of adequate ventilation and adequate circulation. The general surgeon is best qualified to assume full responsibility for the proper care of the critically injured, of patients with multiple injuries, and of patients in traumatic shock. He must assume the risk of transfusing unmatched whole blood and of deferring non-essential radiographs. The emergency and radiology departments may have to be by-passed to save the life of the critically injured patient. The measures required to establish a clear airway, to treat complications which can impair ventilation, to manage shock and hemorrhage and the possible complications of massive transfusions of blood are reviewed.

    The shortening of telomeres with ageing is a well-documented observation; however, the reported number of nucleotides in telomeres varies between different laboratories and studies. Such variability is likely caused by ethnic differences between the populations studied. Until now, there were no studies that investigated the variability of telomere length in a senescent Latvian population of the most common mitochondrial haplogroups, defined as H (45%), U (25%), Y chromosomal N1c (40%) and R1a1 (40%). Telomere length was determined in 121 individuals in different age groups, including a control group containing individuals of 20-40 years old and groups of individuals between 60-70 years old, 71-80 years old, 81-90 years old, and above 90 years old. Telomere length was determined using the Southern blot telomeric restriction fragment assay (TRF). Decreased telomere length with ageing was confirmed, but a comparison of centenarians and individuals between 60-90 years of age did not demonstrate a significant difference in telomere length. However, significant variability in telomere length was observed in the control group, indicating probable rapid telomere shortening in some individuals that could lead up to development of health status decline appearing with ageing. Telomere length measured in mononuclear blood cells (MNC) was compared with the telomere length measured in whole peripheral white blood cells (WBC) using TRF. Telomere length in MNC was longer than in WBC for the control group with individuals 20 to 40 years old; in contrast, for the group of individuals aged 65 to 85 years old, measured telomere length was shorter in MNC when compared to WBC.

    Purpose To study mutations associated with Leber hereditary optic neuropathy (LHON) in patients suspected of having this mitochondrial disorder in a Latvian population. Additional aims were to determine the heteroplasmy status of all non-synonymous polymorphisms identified in the current study and to identify the mitochondrial haplogroups of the studied participants because these factors may contribute to the manifestation of LHON. Methods Twelve patients, including patients in two families, were enrolled in the current study. LHON was suspected based on the findings of ophthalmologic examinations. In clinically affected individuals, the presence of all previously reported LHON-associated mutations was assessed with sequencing analysis. Additionally, the SURVEYOR endonuclease assay was used to detect heteroplasmy. The mitochondrial haplogroups were identified with restriction analysis and the sequencing of hypervariable segment 1. Results In one family (mother and son), there was one primary LHON-associated mutation, G11778A. In addition, one rare previously reported LHON-associated polymorphism, A13637G, was detected in two unrelated patients. A non-synonymous polymorphism at T6253C was found in one individual. This mutation was reported in the background of the 3460 mutation among LHON patients in a Chinese population. No non-synonymous point mutations in mitochondrial DNA were found in five of the study participants. Conclusions Molecular analysis of 12 patients with suspected LHON confirmed the diagnosis in four patients and allowed the use of appropriate prophylactic measures and treatment. Further investigations and additional studies of different populations are necessary to confirm the role of the non-synonymous polymorphisms A13637G and T6253C in the manifestation of LHON and the associations of these polymorphisms with mitochondrial haplogroups and heteroplasmy.

    Background Abnormal lipid levels are considered one of the most significant risk factors for atherosclerosis and coronary artery disease, two of the main causes of death worldwide. Apart from monogenic cases of hypercholesterolemia, most of the common dyslipidemias are caused by a number of low-impact polymorphisms. It has recently been reported that frequent polymorphisms at a large number of loci are significantly associated with one or more blood lipid parameters in many populations. Identifying these associations in different populations and estimating the possible interactions between genetic models are necessary to explain the underlying genetic architecture of the associated loci and their ultimate impact on lipid-associated traits. Methods We estimated the association between 144 common single-nucleotide polymorphisms (SNPs) from published genome-wide association studies and the levels of total cholesterol, low- and high-density lipoprotein–cholesterol, and triglycerides in 1273 individuals from the Genome Database of the Latvian Population. We analyzed a panel of 144 common SNPs with Illumina GoldenGate Genotyping Assays on the Illumina BeadXpress System. Results Ten SNPs at the CETP locus and two at the MLXIPL locus were associated with reduced high-density lipoprotein–cholesterol levels; one SNP at the TOMM40 locus was associated with increased low-density lipoprotein–cholesterol; and four SNPs at the MLXIPL locus were associated with increased log triglyceride levels. There was also a significant correlation between the number of risk alleles and all the lipid parameters, suggesting that the coexistence of many low-impact SNPs has a greater effect on the dyslipidemia phenotype than the individual effects of found SNPs. Conclusion We conclude that the CETP, MLXIPL, and TOMM40 loci are the strongest genetic factors underlying the variability in lipid traits in our population. PMID:25606439

Despite this, girl soldiers often remain an invisible and marginalised group frequently neglected from disarmament, demobilisation and reintegration programmes. This is not just a local issue: with former child soldiers seeking asylum as refugees there is an increasing need for health workers in the destination countries to understand their health needs in order to inform appropriate holistic service provision. This review provides an overview of how the duties and life experiences of girl soldiers, including gender-specific abuses, impacts upon their health and concludes with a summary of recommendations as to how their rehabilitation needs can be addressed.

    Eighty-percent of the US adult population regularly consumes caffeine, but limited information is available on the extent and patterns of use. Caffeine use is a public health issue and its risks and benefits are regularly considered in scientific literature and the lay media. Recently, new caffeine-containing products have been introduced and are widely available on Army bases and are added to rations to maintain cognitive performance. This study surveyed caffeine consumption and demographic characteristics in 990 US Army soldiers. Data were weighted by age, sex, rank, and Special Forces status. Total caffeine intake and intake from specific products were estimated. Logistic regression was used to examine relationships between caffeine use and soldier demographic and lifestyle characteristics. Eighty-two percent of soldiers consumed caffeine at least once a week. Mean daily caffeine consumption was 285 mg/day (347 mg/day among regular caffeine consumers). Male soldiers consumed, on average, 303 mg/day and females 163 mg/day (regular consumers: 365 mg/day for male soldiers, 216 mg/day for female soldiers). Coffee was the main source of caffeine intake. Among young males, energy drinks were the largest source of caffeine intake, but their intake was not greater than older males. Regression analysis indicated an association of higher caffeine intake with male sex, white race, and tobacco use (P<0.01). Most soldiers consume caffeine in levels accepted as safe, but some consume greater quantities than recommended, although definitive information on safe upper limits of caffeine intake is not available. Labels of caffeine-containing products should provide caffeine content so individuals can make informed decisions.

    Strategy of the European Union in efficient energy usage demands to have a higher proportion of renewable energy in the energy market. Since heat pumps are considered to be one of the most efficient heating and cooling systems, they will play an important role in the energy consumption reduction in buildings aimed to meet the target of nearly zero energy buildings set out in the EU Directive 2010/31/EU. Unfortunately, the declared heat pump Coefficient of Performance (COP) corresponds to a certain outdoor temperature (+7 °C), therefore different climate conditions, building characteristics and settings result in different COP values during the year. The aim of this research is to investigate the Seasonal Performance factor (SPF) values of air-to-water heat pump which better characterize the effectiveness of heat pump in a longer selected period of time, especially during the winter season, in different types of residential buildings in Latvian climate conditions. Latvia has four pronounced seasons of near-equal length. Winter starts in mid-December and lasts until mid-March. Latvia is characterized by cold, maritime climate (duration of the average heating period being 203 days, the average outdoor air temperature during the heating period being 0.0 °C, the coldest five-day average temperature being -20.7 °C, the average annual air temperature being +6.2 °C, the daily average relative humidity being 79 %). The first part of this research consists of operational air-towater heat pump energy performance monitoring in different residential buildings during the winter season. The second part of the research takes place under natural conditions in an experimental construction stand which is located in an urban environment in Riga, Latvia. The inner area of this test stand, where air-to-water heat pump performance is analyzed, is 9 m2. The ceiling height is 3 m, all external wall constructions (U = 0.16 W/(m2K)) have ventilated facades. To calculate SPF, the

LM coatings proposed for the protection of divertor plates were considered too. Experiments were performed on a superconducting magnet providing a 5.6 T magnetic field in a 30 liters bore. In a large vacuum chamber (12 m{sup 3}; 6.65 10{sup {minus}4} Pa) lithium cooling system for high temperature reactors was examined. Electromagnetic pumps and flowmeters able to work at lithium temperatures up to 960{degrees}C were tested. A Na loop, where two mounted in line electromagnetic pumps are delivering a 25 atm. pressure. The main Na loop equipped with em. pumps is based on a d=10 cm tubing. LM devices were installed in the Latvian 500 MW nuclear research reactor IRT-5000 too. First, a equipped with conductive e.m. pumps loop, where InGaSn serves as a {gamma}-carrier from activity generator (placed close to the core) to two outer 20 Mrad/h irradiators. Second, a LM system for rector control, where contained in InGaSn indium is used for neutron absorption and reactivity control. A closed cylindrical LM container was installed in the core instead of a traditional control rod. The container is divided in two chambers by means of elastic membranes. The one chamber contains InGaSn, the second GaSn (without In). By means of e.m. pumps the proportion between InGaSn and GaSn in the active zone can be changed ensuring a possibility to control the amount of introduced in the core absorbing material. Long term tests of the system were performed on a zero-power assembly. But for a shorter time the system was inserted in the core of the acting main reactor too and the efficiency of the control was confirmed.

    Olfactory dysfunction following trauma has been widely reported and is currently compensable according to existing American Medical Association guidelines when it occurs in the occupational setting. Its presence and the risk factors for its development, however, have not been clearly delineated in occupationally head injured workers. In order to assess this phenomenon, a series of 365 consecutive head injured workers from 1993-1997 was assessed in order to determine the incidence of post-traumatic olfactory dysfunction and its association with the severity of the head injury, the mechanism of injury and other neurotological abnormalities in the same cohort group. Olfactory dysfunction was identified in 13.7% (9.3% with anosmia, 4.4% with hyposmia/dysosmia). It was more likely where the loss of consciousness > 1 h (p < 0.002), in more severe head injuries (grades II-V) (p < 0.001) and when skull fracture (p < 0.001) occurred. The direction of the blow applied to the skull did not influence its presence, although radiologically confirmed skull fractures in the frontal, occipital, skull base and midface were twice as likely as temporal and parietal fractures to result in an olfactory change. From a neurotologic perspective, approximately 21.9% of head injured workers were determined to have recognizable evidence of cochleovestibular dysfunction. Olfactory dysfunction as a physical finding post-head injury compares favourably with the presence of post-traumatic benign positional paroxysmal vertigo (BPPV) and its atypical variants in 11.2% of head injured workers.

    Aim: This study aims to investigate the seroprevalence of HAV immunity among Iranian soldiers and determine whether vaccination should be given to military draftees. Background: Hepatitis A virus (HAV) is highly contagious in individuals living in crowded conditions such as military centers. To the best of our knowledge, there are limited data about HAV prevalence among Iranian soldiers. Patients and methods: In this cross-sectional study, a total of 1554 soldiers were recruited through a random clustering sampling. Serum anti-HAV antibody was measured by Enzyme-linked immunosorbent assay (ELISA). Statistical analysis was performed using SPSS. Results: A total of 1554 male soldiers with age ranged from 18 to 34 years (mean age: 21.2±1.9 years) at baseline were evaluated. Overall, 80.3% of the analyzed specimens were anti-HAV seropositive. Seroprevalence rates significantly increased with the age. Conclusion: Our results suggest that vaccination for HAV is not necessary for Iranian military draftees. However, the vaccination is recommended for high-risk groups, including anti-HAV seronegative soldiers. PMID:27099669

    Understanding the selection pressures that have driven the evolution of sterile insect castes has been the focus of decades of intense scientific debate. An amenable empirical test bed for theory on this topic is provided by the sterile-soldier caste of polyembryonic parasitoid wasps. The function of these soldiers has been a source of controversy, with two basic hypotheses emerging: the "brood-benefit" hypothesis that they provide an overall benefit for their siblings and the "sex-ratio-conflict" hypothesis that the soldiers mediate a conflict between brothers and sisters by killing their opposite-sex siblings. Here, we investigate the divergent sex-ratio optima of a female embryo's maternal-origin and paternal-origin genes, to determine the potential for, and direction of, intragenomic conflict over soldiering. We then derive contrasting empirically testable predictions concerning the patterns of genomic imprinting that are expected to arise out of this intragenomic conflict, for the brood-benefit versus the sex-ratio-conflict hypothesis of soldier function.

    The ability to accurately and rapidly know the precise location of enemy fire would be a substantial capability enhancement to the dismounted soldier. Acoustic gun-shot detections systems can provide an approximate bearing but it is desired to precisely know the location (direction and range) of enemy fire; for example to know from `which window' the fire is coming from. Funded by the UK MOD (via Roke Manor Research) QinetiQ is developing an imaging solution built around an InGaAs camera. This paper presents work that QinetiQ has undertaken on the Muzzle Flash Locator system. Key technical challenges that have been overcome are explained and discussed in this paper. They include; the design of the optical sensor and processing hardware to meet low size, weight and power requirements; the algorithm approach required to maintain sensitivity whilst rejecting false alarms from sources such as close passing insects and sun glint from scene objects; and operation on the move. This work shows that such a sensor can provide sufficient sensitivity to detect muzzle flash events to militarily significant ranges and that such a system can be combined with an acoustic gunshot detection system to minimize the false alarm rate. The muzzle flash sensor developed in this work operates in real-time and has a field of view of approximately 29° (horizontal) by 12° (vertical) with a pixel resolution of 0.13°. The work has demonstrated that extension to a sensor with realistic angular rotation rate is feasible.

  13. Exoskeleton for Soldier Enhancement Systems Feasibility Study

    2000-09-28

    The development of a successful exoskeleton for human performance augmentation (EHPA) will require a multi-disciplinary systems approach based upon sound biomechanics, power generation and actuation systems, controls technology, and operator interfaces. The ability to integrate key components into a system that enhances performance without impeding operator mobility is essential. The purpose of this study and report are to address the issue of feasibility of building a fieldable EHPA. Previous efforts, while demonstrating progress and enhancing knowledge, have not approached the level required for a fully functional, fieldable system. It is doubtless that the technologies required for a successful exoskeleton have advanced, and some of them significantly. The question to be addressed in this report is have they advanced to the point of making a system feasible in the next three to five years? In this study, the key technologies required to successfully build an exoskeleton have been examined. The primary focus has been on the key technologies of power sources, actuators, and controls. Power sources, including internal combustion engines, fuel cells, batteries, super capacitors, and hybrid sources have been investigated and compared with respect to the exoskeleton application. Both conventional and non-conventional actuator technologies that could impact EHPA have been assessed. In addition to the current state of the art of actuators, the potential for near-term improvements using non-conventional actuators has also been addressed. Controls strategies, and their implication to the design approach, and the exoskeleton to soldier interface have also been investigated. In addition to these key subsystems and technologies, this report addresses technical concepts and issues relating to an integrated design. A recommended approach, based on the results of the study is also presented.

    The requirements for soldier camouflage in the context of modern warfare are becoming more complex and challenging given the emergence of novel infrared sensors. There is a pressing need for the development of adapted fabrics and soldier camouflage devices to provide efficient camouflage in both the visible and infrared spectral ranges. The Military University of Technology has conducted an intensive project to develop new materials and fabrics to further improve the camouflage efficiency of soldiers. The developed materials shall feature visible and infrared properties that make these unique and adapted to various military context needs. This paper presents the details of an advanced measurement campaign of those unique materials where the correlation between multispectral and hyperspectral infrared measurements is performed.

    The present study examines the effect of war and domestic violence on the mental health of child soldiers in a sample consisting of 330 former Ugandan child soldiers (age: 11-17 years, female: 49%). All children had experienced at least 1 war-related event and 78% were additionally exposed to at least 1 incident of domestic violence. Prevalences of posttraumatic stress disorder and major depressive disorder were 33%, and 36%, respectively. Behavioral and emotional problems above clinical cutoff were measured in 61%. No gender differences were found regarding mental health outcomes. War experience and domestic violence were significantly associated with all mental health outcomes. The authors' findings point to the detrimental effects of domestic violence in addition to traumatizing war experiences in child soldiers.

    Background Substantial attention and resources are aimed at the reintegration of child soldiers, yet rigorous evaluations are rare. Methods This tracer study was conducted among former child soldiers (N=452) and never-recruited peers (N=191) who participated in an economic support program in Burundi. Socio-economic outcome indicators were measured retrospectively for the period before receiving support (T1; 2005–06); immediately afterwards (T2; 2006–07); and at present (T3; 2010). Participants also rated present functional impairment and mental health indicators. Results Participants reported improvement on all indicators, especially economic opportunity and social integration. At present no difference existed between both groups on any of the outcome indicators. Socio-economic functioning was negatively related with depression- and, health complaints and positively with intervention satisfaction. Conclusion The present study demonstrates promising reintegration trajectories of former child soldiers after participating in a support program. PMID:23095403

    1998-06-30

    Chronic stress causes multiple biochemical and physiological changes in the human organism. Recently we have identified stressin, a human serum glycoprotein that was significantly increased in sera of prisoners released from Serbian concentration camps. To eliminate malnutrition and maltreatment as possible causes for the increased stressin concentration, we have analyzed stressin in sera of 40 professional soldiers after involvement in major military activity and compared it to stressin in sera of 20 control individuals. As expected, the sera of professional soldiers contained more than 2.2 times higher concentrations of stressin than control sera. It is interesting that, contrary to expectations, the natural killer cell activity of professional soldiers was normal or even increased. We hypothesize that this might be an effect of winning the war that could have, at least temporarily, erased the immunosuppressive effects of stress.

    Given the various developments in former child soldiers' psychosocial well-being over time, the question arises as to which factors are associated with the prevalence of psychological distress. An ongoing debate points to the plausible importance of child soldiering-related and post-child soldiering factors. This study is an exploratory analysis of both types of association with former child soldiers' psychosocial well-being in the longer term. Follow-up data on a convenience sample of 424 northern Ugandan former child soldiers are analysed. Psychological symptoms are assessed by a review of the intake and assessment forms of the Rachele Rehabilitation Centre, which were not validated and did not include a standardised translation into the local language. These psychological symptoms and possible associated factors are analysed using binary logistic regression analysis. Thereby, both child soldiering-related and post-child soldiering variables are accounted for. The outcomes reveal almost no significant main effects of child soldiering-related variables, while a range of post-child soldiering variables (number of meals a day, school attendance, insults and professional support) are clearly associated with the prevalence of the measured psychological symptoms in the longer term. These exploratory conclusions should be further investigated in representative samples of former child soldiers using validated assessment tools.

  19. Historic channel change along Soldier Creek, Northeast Kansas

    2002-01-01

    To assess historical channel change along Soldier Creek, northeast Kansas, available information from eight U.S. Geological Survey streamflow-gaging stations was analyzed. At each gaging station, channel change was assessed using channel-bed elevation as the primary indicator variable. Changes in channel-bed elevation were inferred from changes in the stage associated with the mean annual discharge at each station. The variables channel width, channel area, and streamflow velocity were used as additional indicators of change. Results indicated that the most substantial channel changes occurred downstream from Rocky Ford at the Soldier Creek streamflow-gaging stations located near Topeka and Delia. The available evidence indicated that the channelization of Soldier Creek, completed in 1961, was likely the primary cause of the channel changes at these locations. The decreasing base level provided by the Kansas River also may have contributed to the channel changes at these locations. At the Soldier Creek gaging station near Topeka, immediate effects of the channelization included a decrease in channel-bed elevation of about 5 feet and an increase in channel width of about 35 feet. The instability introduced by the channelization caused channel-bed degradation that moved upstream at the rate of about 0.7 to 1.2 miles per year. At the Soldier Creek gaging station near Delia, located about 12 miles upstream from the upstream end of the channelized section, channel-bed degradation began during the 1970s and resulted in a net decrease in channel-bed elevation of about 5 feet by 1999. The available evidence indicated that Soldier Creek at and upstream from Rocky Ford has not been substantially affected by the upstream-progressing channel-bed degradation as of 2001. In this part of the basin other causes of channel change, such as land use and floods, may be relatively more important.

    KIRs (killer Ig-like receptors) expressed on natural killer (NK) cells are an important component of innate (and adaptive) immunity. They are either activatory or inhibitory, and certain KIRs are known to interact with specific motifs of HLA Class I molecules, which is very crucial in determining whether a cell is targeted to lysis or otherwise. Latent autoimmune diabetes in adults (LADA) is a slowly progressive form of autoimmune diabetes, with an adult onset (>30 years). Because autoantibodies and autoimmunity involved are involved in the etiology of LADA, KIRs might play an important role in conferring susceptibility to or protection against the disease. The purpose of this study was to identify killer immunoglobulin-like receptor (KIR) genes, which are associated with susceptibility to and protection against type 1 diabetes in Latvian and Asian Indian patients with LADA. KIR and HLA-C ligand genotyping was performed using PCR-SSP in LADA patients from Latvia (n= 45) with age- and sex-matched controls (n= 92) and from India (n= 86) with controls (n= 98). Results showed that in Latvian patients with LADA, KIRs 2DL1, 2DS2, and 2DS4 were associated with susceptibility and KIR 2DS5 with protection. In Asian Indian LADA patients, KIRs 2DL5 and 3DL1 were associated with susceptibility and KIRs 2DS1 and 2DS3 with protection. Stratification analyses for KIRs that bind to HLA-C1 and C2 were performed. We concluded that KIRs are important in conferring susceptibility (or protection) to adult patients with LADA in both our study populations. However the KIR genes (and their HLA-C ligands) conferring susceptibility or protection in these two populations differ, showing a role of ethnicity in disease susceptibility.

    Abstract Our objective was to determine: 1) whether the checkpoint kinase 2 (CHEK2) del5395 (g.27417113-27422508 del, NC_000022.11) is a founder mutation in the Latvian population, 2) if there is an association between CHEK2 del5395 mutation and cancer risk, and 3) and whether the CHEK2 del5395 mutation impacts cancer predisposition in Chernobyl disaster liquidators (the civil and military personnel who were called upon to deal with consequences of the 1986 nuclear disaster) as well as geriatric populations. We recruited 438 breast cancer patients, 568 colorectal cancer patients, 399 ovarian cancer patients, 419 prostate cancer patients, 526 healthy blood donors, 480 Chernobyl disaster liquidators and 444 geriatric cancer-free participants. DNA samples were isolated from blood samples and subjected to multiplex polymerase chain reaction (PCR). The truncation of del5395 was estimated by fragment size of the multiplex PCR.All groups were compared to the healthy blood donors using Fisher’s exact test. All p values were two-sided and the odds ratios (OR) calculated by two-by-two table. In cancer groups, the del5395 mutation was most frequently observed in the ovarian cancer group (1.00%, OR = 1.32). In control groups, the del5395 mutation was most frequent (0.76%) in the healthy donors, which exceeded its frequency in the Chernobyl liquidators group and the geriatric group by 0.01 and 0.08%, respectively. For all groups, the OR appeared to be >1 only in ovarian cancer patients. However, OR rates showed no statistical significance in either cancer or control groups, with the p value fluctuating within the range of 0.39-1.00. The CHEK2 gene del5395 is a founder mutation in the Latvian population, which, however, does not have a direct impact on genetic predisposition toward colorectal, breast, ovarian and prostate cancer.

    Background: Military service is a stressful task that influences the life style of army personnel. Several factors can make soldiers less capable of coping with stressful events; so they may try to start drug abuse or increase in the amount or diversity of substance abuse. Understanding factors responsible for this misbehavior among soldiers is crucial for their commanders to modify these factors. Objectives: This study aimed to determine the predictors of change in substance abuse status in soldiers. Patients and Methods: This cross-sectional research was conducted to evaluate the substance abuse status among Iranian soldiers in 2010. The target population was the soldiers who had spent at least 3 months of their military service. Cluster sampling was done from army service garrisons in 12 provinces in Iran. A total of 3960 soldiers were selected with different levels of education and age. Data gathering was done with demographic questionnaires, Texas Christian university (TCU) drug screen II and ASI questionnaire (fifth edition). Four types of dependent variables were defined: “improvement”, “without change”, “deterioration”, and “severe deterioration”. Backward ordinal regression analysis was done and P values, OR, and SE were calculated by SPSS19 software. Results: Totally, 6.7% of soldiers improved, 82% remained without change, 6.1% deteriorated, and 5.2% severely deteriorated with regard to their substance abuse. Modifiable predictors were distance from home lower than 200 km (OR =1.54), bad relationship with commanders (OR = 1.88), service place dissatisfaction (OR = 1.39), and always feeling lonely (OR = 1.83). Non-modifiable factors were alcohol use within family and friends (P = 0.000); psychiatric drug use history (OR = 1.72); suicidal attempt history (OR = 1.31); divorce, separation, and extramarital contact (P = 0.001); unemployment (P = 0.019); leisure time dissatisfaction (P = 0.004); living alone (OR = 2.43); and substance abuse

    The many constraints and psychologically demanding situations to which French soldiers are subjected (living conditions, operational pace, scenes of exaction, hostile crowds, combat situations) have justified a psychiatrist being posted to the theatre of operation Sangaris, in the Central African Republic, soon after the military intervention began. While the psychiatrist's activity is typical of psychiatry in operational situations,.the configuration of the conflict- a civil war - and its impact on the psyche of the soldiers making up the task force have resulted in these practices being adapted and acknowledgement of the need to update skills.

    Glycosaminoglycans (GAG) are believed to be important in the pathogenesis of atherosclerosis. We have previously demonstrated that areas of injured aorta that have been re-endothelialized accumulate increased amounts of lipid and GAG when compared to areas remaining de-endothelialized. We have now examined the net incorporation of labeled precursors into the individual GAG present in both re-endothelialized and de-endothelialized areas of rabbit aorta. Aortic tissue was examined at 2-3 and 10-14 weeks after a denuding injury by incubating tissue minces with (/sup 3/H)glucosamine and sodium (/sup 35/S)sulfate for 24 hr. Following incubation, the aortic GAG were isolated and assayed for uronic acid concentration and radioactivity. Results indicate that the total GAG concentration was significantly greater in the re-endothelialized as compared to de-endothelialized areas. The concentration in uninjured aorta was 9.01. The difference between the injured tissues was attributable to increased concentrations of sulfated GAG. Hyaluronic acid and chondroitin sulfate were the most metabolically active of the GAG in either uninjured or injured aorta, together accounting for over 75% of the /sup 3/H label. The /sup 3/H specific radioactivities of the four GAG in the short-term, re-endothelialized subgroup were all increased nearly twice that found in uninjured and de-endothelialized tissues. With the exception of heparan sulfate, no significant differences were noted in the /sup 3/H specific radioactivities between the re-endothelialized and de-endothelialized areas in the long-term subgroup. These results indicate that, relative to adjacent areas of de-endothelialization, GAG preferentially accumulate in re-endothelialized areas even as early as 2-3 weeks following a denuding injury.

    Major trauma induces metabolic alterations that contribute to the systemic immune suppression in severely injured patients and increase the risk of infection and posttraumatic organ failure. Nutrition modulation of cellular processes has evolved into a high-priority therapy, backed by substantial scientific evidence. The appropriate selection, timing, and dose of nutrients required for metabolic resuscitation must be individualized and goal directed. Ideally, the nutritional interventions for warfighters will be developed strategically based on the extent of injuries and underlying deficiencies and will be designed to provide the nutrients necessary to balance hypermetabolic processes, heal wounds, and promote optimal recovery.

    Objective To determine the statistical characteristics of blood pressure (BP) readings from a large number of head‐injured patients. Methods The BrainIT group has collected high time‐resolution physiological and clinical data from head‐injured patients who require intracranial pressure (ICP) monitoring. The statistical features of this dataset of BP measurements with time resolution of 1 min from 200 patients is examined. The distributions of BP measurements and their relationship with simultaneous ICP measurements are described. Results The distributions of mean, systolic and diastolic readings are close to normal with modest skewing towards higher values. There is a trend towards an increase in blood pressure with advancing age, but this is not significant. Simultaneous blood pressure and ICP values suggest a triphasic relationship with a BP rising at 0.28 mm Hg/mm Hg of ICP, for ICP up to 32 mm Hg, and 0.9 mm Hg/mm Hg of ICP for ICP from 33 to 55 mm Hg, and falling sharply with rising ICP for ICP >55 mm Hg. Conclusions Patients with head injury appear to have a near normal distribution of blood pressure readings that are skewed towards higher values. The relationship between BP and ICP may be triphasic.

    This study examined the impact of repeated exposure to combat on combat stress reaction (CSR). Soldiers diagnosed with CSR during the Lebanon War (N = 382) were compared with a matched control group of soldiers who fought in the same units but did not manifest symptoms of CSR (N = 334). CSR in the Lebanon War was found to be related to the psychological outcome the soldier experienced in previous wars. The CSR rate in the Lebanon War was higher in soldiers who had experienced an episode of CSR in a previous war than in soldiers with no past combat experience. However, CSR rates were lower among soldiers who had not had an episode of CSR in a previous war than among soldiers with no prior combat experience. High intensity of combat in Lebanon was found to increase both the detrimental and favourable effects of prior combat experience. PMID:3602235

    Background The Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS) has found that the proportional elevation in the US Army enlisted soldier suicide rate during deployment (compared with the never-deployed or previously deployed) is significantly higher among women than men, raising the possibility of gender differences in the adverse psychological effects of deployment. Method Person-month survival models based on a consolidated administrative database for active duty enlisted Regular Army soldiers in 2004–2009 (n = 975 057) were used to characterize the gender × deployment interaction predicting suicide. Four explanatory hypotheses were explored involving the proportion of females in each soldier’s occupation, the proportion of same-gender soldiers in each soldier’s unit, whether the soldier reported sexual assault victimization in the previous 12 months, and the soldier’s pre-deployment history of treated mental/behavioral disorders. Results The suicide rate of currently deployed women (14.0/100 000 person-years) was 3.1–3.5 times the rates of other (i.e. never-deployed/previously deployed) women. The suicide rate of currently deployed men (22.6/100 000 person-years) was 0.9–1.2 times the rates of other men. The adjusted (for time trends, sociodemographics, and Army career variables) female:male odds ratio comparing the suicide rates of currently deployed v. other women v. men was 2.8 (95% confidence interval 1.1–6.8), became 2.4 after excluding soldiers with Direct Combat Arms occupations, and remained elevated (in the range 1.9–2.8) after adjusting for the hypothesized explanatory variables. Conclusions These results are valuable in excluding otherwise plausible hypotheses for the elevated suicide rate of deployed women and point to the importance of expanding future research on the psychological challenges of deployment for women.

    The Third International Congress on Soldiers' Physical Performance (ICSPP) was held on August 18-21, 2014 in Boston, MA, where it had a record attendance of 374 registrants from 27 countries. The Congress included 8 invited keynote lectures, 12 symposia, 1 featured science session, more than 200 oral and poster free communication sessions, 8 thematic poster sessions, and a Warfighter Readiness Roundtable. Collectively, the presentations focused on a fundamental premise that soldiers are the center of warfighting capability, and the human service member is the prime resource and key enabler of all warfighting systems. The intent of the ICSPP series is to focus on the soldier-the individual service member. As we move forward with focus placed on the human dimension of soldiering, the key to our scientific success and what will prove to be transformative will be the extent to which we can operationalize and disseminate our scientific knowledge for the benefit of our soldiers on the ground. The Congress fostered important scientific exchange, and dialog centered on improving military physical performance and readiness. As countries around the globe respond to current and emerging threats to their national security, it is increasingly clear that we must ensure optimal human performance of our military personnel. By taking advantage of the science and applications of physical fitness and injury prevention research, we can leverage our increased understanding for the optimal application of physical readiness processes while minimizing the injury risk potential. We believe that the continued scientific and evidence-based dialog across international partners will prove to be transformative in identifying the most effective strategies for human performance optimization in the 21st century. Innovation, leveraging current state-of-the-science, and international partnerships were all key themes throughout the Congress. From the ICSPP scientific program, it was clear that there

  9. Infertility in spinal-cord injured male.

    PubMed

    Ver Voort, S M

    1987-02-01

    Sterility in spinal-cord injured (SCI) men is believed to be caused by ejaculatory dysfunction, genital ductal blockage secondary to infection, and/or impaired spermatogenesis. Semen from SCI men demonstrates diminished numbers of motile, morphologically normal sperm. Testicular biopsies demonstrate impaired spermatogenesis. Leydig and Sertoli cells appear to be normal. Endocrine evaluations reveal normal testosterone levels with an adequate Leydig cell reserve. Luteinizing hormone (LD) and follicle-stimulating hormone (FSH) levels are normal or high with normal or exaggerated stimulation responses. Acute depressions in testosterone, FSH, and LH levels can be seen following SCI, most markedly in quadriplegics. A normal hypothalamic-pituitary-testicular axis is implied by these findings, indicating a primary hypogonadism. Causes of impaired spermatogenesis may include local testicular temperature elevations, nondrainage of the reproductive tract, antisperm antibodies, and recurrent genitourinary infections. Treatment of infertility involves removal of these offending factors, and research is needed to correlate the impaired spermatogenesis with these factors.

    OBJECTIVES: To examine variation across US hospitals in evaluation for occult fractures in (1) children <2 years old diagnosed with physical abuse and (2) infants <1 year old with injuries associated with a high likelihood of abuse and to identify factors associated with such variation. METHODS: We performed a retrospective study in children <2 years old with a diagnosis of physical abuse and in infants <1 year old with non-motor vehicle crash–related traumatic brain injury or femur fractures discharged from 366 hospitals in the Premier database from 2009 to 2013. We examined across-hospital variation and identified child- and hospital-level factors associated with evaluation for occult fractures. RESULTS: Evaluations for occult fractures were performed in 48% of the 2502 children with an abuse diagnosis, in 51% of the 1574 infants with traumatic brain injury, and in 53% of the 859 infants with femur fractures. Hospitals varied substantially with regard to their rates of evaluation for occult fractures in all 3 groups. Occult fracture evaluations were more likely to be performed at teaching hospitals than at nonteaching hospitals (all P < .001). The hospital-level annual volume of young, injured children was associated with the probability of occult fracture evaluation, such that hospitals treating more young, injured patients were more likely to evaluate for occult fractures (all P < .001). CONCLUSIONS: Substantial variation in evaluation for occult fractures among young children with a diagnosis of abuse or injuries associated with a high likelihood of abuse highlights opportunities for quality improvement in this vulnerable population.

    In social aphids of the genus Tuberaphis a cysteine protease gene of the family cathepsin B exhibits soldier-specific expression and intestinal protease production. The product is orally excreted and injected by soldier nymphs into natural enemies, thereby exerting an insecticidal activity. In an attempt to gain insights into when and how the novel venomous protease for the altruistic caste has evolved, we investigated the soldier-specific type (S-type) and nonspecific type (N-type) cathepsin B genes from social and nonsocial aphids. All the social aphids examined, representing the genera Tuberaphis, Astegopteryx, and Cerataphis, possessed both the S-type and N-type genes. Phylogenetically distant nonsocial aphids also possessed cathepsin B genes allied to the S-type and the N-type, indicating the evolutionary origin of these genes in the common ancestor of extant aphids. In Tuberaphis species the S-type genes exhibited significant soldier-specific expression and accelerated molecular evolution whereas the N-type genes did not. In Astegopteryx and Cerataphis species, meanwhile, both the S-type and N-type genes exhibited neither remarkable soldier-specific expression nor accelerated molecular evolution. These results suggest that the S-type gene acquired the soldier-specific expression and the venom function after divergence of the genus Tuberaphis. On the structural model of the S-type protease of Tuberaphis styraci the accelerated molecular evolution was associated with the molecular surface rather than the catalytic cleft, suggesting that the venom activity was probably acquired by relatively minor modifications on the molecular surface rather than by generation of a novel active site. In Cerataphis jamuritsu the S-type gene was, although containing a stop codon, structurally almost intact and still transcribed, suggesting recent pseudogenization of the gene copy and possible relevance to relaxed functional constraint in the highly multiplied protease gene family

    Computer vision capabilities have long been available to advanced sensor systems such as those on aircraft, UAVs, helicopters, and ground scout vehicles; but to date, they have not been available to the dismounted soldier. This is understandable since the size/weight/cost metrics of carrying sensors and the image processing, interaction, and display capabilities, not to mention the power supply, have been prohibitive. But recent advances in uncooled IR sensors (up to QVGA), coupled with the steady advances in EO sensors (VGA+) and in microelectronics, are now making the prospect of computer vision for the foot soldier feasible for the first time. In this paper, we develop our initial approaches to all aspects of this problem: (a) sensor system integration, (b) image processing algorithms and initial hardware vision, and (c) display and interaction. As a prototype compute/display platform, we do initial development based on a lightweight commercial wearable computer and helmet-mounted display.

    Virtual reality exposure (VRE) therapy is a promising treatment for a variety of anxiety disorders and has recently been extended to the treatment of posttraumatic stress disorder (PTSD). In this article, the authors briefly review the rationale for VRE and its key processes. They illustrate the treatment with an active-duty Army soldier diagnosed with combat-related PTSD. Six sessions of VRE were provided using an immersive simulation of a military convoy in Iraq. Self-reported PTSD symptoms and psychological distress were reduced at posttreatment relative to pretreatment reports, as assessed by the PTSD Checklist-Military Version and the Behavior and Symptom Identification Scale-24. The case outcomes parallel those reported in the research with other disorders and suggest the applicability of VRE in treating active duty soldiers with combat-related PTSD. PMID:18612993

    Counterinsurgency (COIN) has become the cornerstone of the military's strategy to combat terrorist threats. COIN operations are complex and often expose soldiers to unfamiliar stressors as they fight the enemy while developing and maintaining rapport with the local populace. Utilizing a retrospective record review protocol, we examined 282 mental health files of soldiers assigned to a brigade combat team that operated from a large forward operating base in Iraq during the counterinsurgency campaign. Most reported sleep disturbance, depression, anxiety, irritability, and conflict with supervisors related to either operational stress, exposure to direct combat, or home front concerns. Most received brief individual supportive therapy or attended solution-focused group counseling emphasizing life skills training, post-traumatic stress treatment, women's support, or relationship skills. Psychopharmacologic treatment was an essential adjunct to the counseling program. Results indicate that supporting a COIN deployment requires a comprehensive mental health program that can respond to a wide range of mental health problems. PMID:22645874

    The U.S. Army Research Laboratory's (ARL) Computational and Information Sciences Directorate (CISD) has long been involved in autonomous asset control, specifically as it relates to small robots. Over the past year, CISD has been making strides in the implementation of three areas of small robot autonomy, namely platform autonomy, Soldier-robot interface, and tactical behaviors. It is CISD's belief that these three areas must be considered as a whole in order to provide Soldiers with useful capabilities. In addressing the Soldier-robot interface aspect, CISD has begun development on a unique dismounted controller called the Future Operator Control Unit: Soldier (FOCU:S) that is based on an Apple iPod Touch. The iPod Touch's small form factor, unique touch-screen input device, and the presence of general purpose computing applications such as a web browser combine to give this device the potential to be a disruptive technology. Setting CISD's implementation apart from other similar iPod or iPhone-based devices is the ARL software that allows multiple robotic platforms to be controlled from a single OCU. The FOCU:S uses the same Agile Computing Infrastructure (ACI) that all other assets in the ARL robotic control system use, enabling automated asset discovery on any type of network. Further, a custom ad hoc routing implementation allows the FOCU:S to communicate with the ARL ad hoc communications system and enables it to extend the range of the network. This paper will briefly describe the current robotic control architecture employed by ARL and provide short descriptions of existing capabilities. Further, the paper will discuss FOCU:S specific software developed for the iPod Touch, including unique capabilities enabled by the device's unique hardware.

    Sterigmatocystin (STC) is a carcinogenic and mutagenic mycotoxin produced by fungi of many Aspergillus species. The aim of this research was to test the stability of STC during the bread making process and to check bread samples from the Latvian market for STC contamination, using a previously developed electrospray positive ionisation (ESI(+)) liquid chromatography-tandem mass spectrometry (LC-MS/MS) method. Wheat grain naturally contaminated with STC was used for bread baking. STC was found to be stable during the bread-making process. In the food survey 17% of the analysed breads were positive for STC, with concentration levels of 2-7 μg kg(-1). One out of six rye bread samples, one out of nine rye-wheat bread samples and three out of 14 wheat bread samples were contaminated with STC. Four out of five contaminated samples contained whole grains as the main ingredient. We conclude that whole grain bread may be a possible source of STC, although even STC-positive bread samples identified in this study contained quite low toxin levels. PMID:23606050

    Insulin-dependent diabetes mellitus (IDDM) is one of the most common chronic diseases. It is an autoimmune disease. Genes contributing the most for development of IDDM are located on chromosome 6p21.3 in the region called the major histocompatibility complex (MHC). HLA-DQ8/DR4 and DQ2/DR3 have shown positive association with IDDM, while DQ6 has negative association with IDDM in most Caucasian populations. The location of the tumor necrosis factor alpha (TNF-alpha) gene in the MHC suggests the role of TNF in the etiology of IDDM as an autoimmune disease. The TNF region contains several polymorphisms that are associated with different levels of TNF-alpha production and susceptibility to autoimmune and infectious diseases. Ninety-two Latvian IDDM patients corresponding to WHO diagnostic criteria and 107 unrelated age- and sex-matched healthy controls were analyzed for the frequency of TNF-alpha alleles to test the hypothesis that TNF-alpha is associated with IDDM. We found that TNF-alpha microsatellite allele 2 is associated with IDDM, 29/92 (32%), versus 14/107 (13%) in healthy controls. The test of the strongest association of the MICA A5 allele and TNF-alpha allele 2 with IDDM showed that both are independently associated with the disease.

    BACKGROUND. The need for appraisal of oral health-related quality of life has been increasingly recognized over the last decades. The aim of this study was to develope a Latvian and a Russian version and test the validity of the Oral Health Impact Profile (OHIP-49) for use among adults in Latvia. METHODS. The original English version of the OHIP-49 was translated using the forward-backward technique, pilot-tested, and then applied to 60 adults aged 18 years and above. The questionnaire was filled out during face-to-face interviews conducted by one specialist. The internal consistency of the questionnaire was evaluated using Cronbach's alpha (α) coefficient and inter-item and item-total correlations. Discriminant and convergent validities were assessed. RESULTS. Cronbach's α was estimated to be 0.96. Inter-item correlations coefficients ranged from 0.19 to 0.91, with averige value 0.35, while item-total correlations coefficients from 0.14 to 0.86. CONCLUSIONS. The OHIP-49 is a reliable and valid questionnaire for the assessment of OHRQoL among adults in Latvia.

  5. Spiteful soldiers and sex ratio conflict in polyembryonic parasitoid wasps.

    2007-04-01

    The existence of spiteful behaviors remains controversial. Spiteful behaviors are those that are harmful to both the actor and the recipient, and they represent one of the four fundamental types of social behavior (alongside selfishness, altruism, and mutual benefit). It has generally been assumed that the conditions required for spite to evolve are too restrictive, and so spite is unlikely to be important. This idea has been challenged in recent years, with the realization that localized competition can relax the conditions required for spite to evolve. Here we develop a theoretical model for a prime candidate for a spiteful behavior, the production of the sterile soldier caste in polyembryonic wasps. Our results show that (a) the biology of these soldiers is consistent with their main role being to mediate conflict over the sex ratio and not to defend against competitors and (b) greater conflict will occur in more outbred populations. We also show that the production of the sterile soldier caste can be classed as a spiteful behavior but that, to an extent, this is merely a semantic choice, and other interpretations such as altruism or indirect altruism are valid. However, the spite interpretation is useful in that it can lead to a more natural interpretation of relatedness and facilitate the classification of behaviors in a way that emphasizes biologically interesting differences that can be empirically tested.

  6. On the skin of a soldier: The story of flogging.

    After Farrier-Major Critton struck the 150th lash on the back of Private Frederick John White, at the end of a common disciplinary session at Hounslow Barracks, West London, in 1846, the soldier, whistling, walked himself to the infirmary to have his wounds dressed. His skin healed promptly, but 4 weeks later, he was found dead in his dormitory. The army medical officers, after performing an autopsy, reached the conclusion that the soldier had died from inflammation of internal organs but excluded any connection with flogging. This version of facts did not convince the coroner for Middlesex, who decided to open an inquest. After 3 more weeks of inquiry and 2 more postmortem examinations, the famous dermatologist Erasmus Wilson contradicted the army officers by affirming that the soldier had indeed died from the effects of flogging as the analysis of the cutaneous lesions and underneath would demonstrate. This contribution will detail how the inquest into the death of Private John White sparked a medical debate on the effects of military flogging to the skin. The discussion raised by the publication of the details of the autopsies demonstrated that different and opposing points of view coexisted in the Victorian period concerning the relation between external lacerations and internal organs in cases of flogging.

    Sagem Defense Securite has been awarded a 800M euro contract for the French infantrymen modernisation programme. This programme covers the development, the qualification and the production of about 32 000 soldier systems to equip all the French infantry starting fielding in 2008. The FELIN soldier system provides the infantryman with an integrated system increasing dramatically the soldier capability in any dismounted close combat domains. Man remains at the centre of the system, which can interface equipments or systems already fielded and future equipments to match any customer's needs. Urban operations are carefully addressed thanks to a versatile and modular solution and a dedicated C4I system, Sagem Defense Securite is a European leader in defence electronics and takes part of this major French Army transformation programme, which will play a key role in the Info Centric Network initiatives promoted in France and other countries. This paper summarises the system solutions selected by the French Army with a focus on the networked capabilities and the optronic devices.

  8. Drinking histories of fatally injured drivers

    2002-01-01

    Context: About 30% of drivers killed in crashes have high blood alcohol concentrations (BACs) of 0.10+ g/dl. There is a question about whether these drivers primarily are problem drinkers who chronically drink and drive—the so-called hard core drinking drivers. Objective: To investigate drinking histories of fatally injured drivers in relation to their BACs. Design and participants: Retrospective cohort study of 818 fatally injured drivers who were included in the 1993 National Mortality Followback Survey (a national sample of US deaths in which next of kin were interviewed) and whose BACs were recorded by the Fatality Analysis Reporting System, a census of US traffic deaths. Main outcome measure: Problem drinking indicators. Results: At least one indicator of potential problem drinking, primarily heavy drinking, was reported for 68% of drivers with very high BACs (0.15+ g/dl), 41% with BACs of 0.10–0.14 g/dl, 32% with BACs of 0.01–0.09 g/dl, and 7% with zero BACs. Spouses provided more credible responses than other relatives: they were more likely to report at least occasional drinking and driving among deceased drivers with high BACs. For the most direct signs of problem drinking (described as a problem drinker during the last month of life or frequently driving after having five or more drinks), spousal reports suggested the prevalence of problem drinking among drivers with very high BACs was 22% (having both indicators), 32% (frequently driving after having five or more drinks), 44% (described as problem drinker), or 57% (having either indicator). Conclusions: Drivers with BACs of 0.10+ g/dl were far more likely than sober drivers to be described as having markers of problem drinking. However, many did not have indicators suggestive of problem drinking. In addition to programs focused on repeat offenders or problem drinkers, countermeasures such as sobriety checkpoints that target a broader spectrum of drinking drivers are appropriate.

    A range of behavioural strategies and sensory abilities allows animals to minimize costs involved in food search. By building a network of tunnels and presenting a large number of soldiers (i.e., trophically dependent individuals), Nasutitermes spp. termites feature behaviours that imply additional costs during this process. Here we evaluated N. aff. coxipoensis foraging strategies focusing on the role of soldiers during foraging. Field experiments were carried out via nests transplantation to dune areas, and laboratory experiments evaluated termite responses to sternal gland chemical signals from workers and soldiers. N. aff. coxipoensis presented primarily nocturnal foraging. Soldiers typically initiated foraging; however, in established trails, the number of workers was always higher than that of soldiers. The number of trails remained constant over time, while the number of tunnels increased linearly over time. A higher proportion of tunnels originated in surrounding areas than directly from the nests. At observation points with tunnels, there were more stationary than walking soldiers; the opposite was true at observation points without tunnels. In mixed groups, the workers chose to follow soldier chemical signals, and in these groups, soldiers were the first to follow trails. Our results allowed us to identify a not common foraging strategy in termite species; which included the establishment of trails followed by construction of tunnels. Such foraging strategies occur predominantly at night and soldiers play a key role in the foraging process. This foraging strategy reported here seems to be employed to optimize energetic gain.

  11. Energy sources for the future dismounted soldier, the total integration of the energy consumption within the soldier system

    NASA Astrophysics Data System (ADS)

    Raadschelders, Jillis W.; Jansen, Tiny

    At present, the energy supply for the electronic equipment of the soldier is problematic. Each component has its own battery pack. These battery packs are not interchangeable and each requires its own charger. Furthermore, because they are all dimensioned to deliver the peak power for each item of equipment, this leads to a higher battery weight than necessary. It is expected that the system of the future soldier will use a central power source to supply the energy for all the different components. An energy bus will be integrated within the soldier's system for this. The different components will generate their required voltages from the bus voltage by using high efficiency dc/dc converters. The use of an energy bus with local voltage conversion will facilitate inter-operability between different forces. The energy sources can easily be exchanged. For the near future, batteries are still considered to be the best option for the energy source. Rechargeable batteries are preferred above non-rechargeable ones due to logistic and environmental problems. For the long-term replacement of batteries, the direct methanol fuel cell (DMFC) is considered a viable option. Several different battery packs were tested for their capability to supply both the required energy and power during a 24 h mission. The tests were carried out with a controlled power method, as maximum power should be deliverable during 10% of the operation time.

    PSMA6 (rs2277460, rs1048990), PSMC6 (rs2295826, rs2295827) and PSMA3 (rs2348071) genetic diversity was investigated in 1438 unrelated subjects from Latvia, Lithuania and Taiwan. In general, polymorphism of each individual locus showed tendencies similar to determined previously in HapMap populations. Main differences concern Taiwanese and include presence of rs2277460 rare allele A not found before in Asians and absence of rs2295827 rare alleles homozygotes TT observed in all other human populations. Observed patterns of SNPs and haplotype diversity were compatible with expectation of neutral model of evolution. Linkage disequilibrium between the rs2295826 and rs2295827 was detected to be complete in Latvians and Lithuanians (D´ = 1; r2 = 1) and slightly disrupted in Taiwanese (D´ = 0.978; r2 = 0.901). Population differentiation (FST statistics) was estimated from pairwise population comparisons of loci variability, five locus haplotypes and PSMA6 and PSMC6 two locus haplotypes. Latvians were significantly different from all Asians at each of 5 SNPs and from Lithuanians at the rs1048990 and PSMC6 loci. Lithuanian and Asian populations exhibited similarities at the PSMC6 loci and were different at the PSMA6 and PSMA3 SNPs. Considering five locus haplotypes all European populations were significantly different from Asian; Lithuanian population was different from both Latvian and CEU. Allele specific patterns of transcription factor binding sites and splicing signals were predicted in silico and addressed to eventual functionality of nucleotide substitutions and their potential to be involved in human genome evolution and geographical adaptation. Current study represents a novel step toward a systematic analysis of the proteasomal gene genetic diversity in human populations. PMID:25606411

    Prior studies on racial and ethnic disparities in survival after motor vehicle crashes have examined only population-based death rates or have been restricted to hospitalized patients. In the current study, we examined 3 components of crash survival by race/ethnicity: survival overall, survival to reach a hospital, and survival among those hospitalized. Nine years of data (from 2000 through 2008) from the National Automotive Sampling System Crashworthiness Data System were used to examine white non-Hispanic, black non-Hispanic, and Hispanic drivers aged ≥15 years with serious injuries (injury severity scores of ≥9). By using multivariable logistic regression, we found that a driver's race/ethnicity was not significantly associated with overall survival after being injured in a crash (for blacks, odds ratio (OR) = 0.69, 95% confidence interval (CI): 0.36, 1.32; for Hispanics, OR = 1.00, 95% CI: 0.59, 1.72), and blacks and Hispanics were equally likely to survive to be treated at a hospital compared with whites (for blacks, OR = 1.00, 95% CI: 0.52, 1.93; for Hispanics, OR = 1.13, 95% CI: 0.71, 1.79). However, among patients who were treated at a hospital, blacks were 50% less likely to survive 30 days compared with whites (OR = 0.50, 95% CI: 0.33, 0.76). The disparity in survival after serious traffic injuries among blacks appears to occur after hospitalization, not in prehospital survival. PMID:23371352

    The present study evaluated the association among sex, sport, and injured body region of sport injuries. The subjects were 329 men and 127 women, ranging in age from 17 to 28 years, attending classes in the departments of Physical Training and Sport of Atatürk University (Erzurum, Erzincan, and Ağri in Turkey). There were no differences between men and women in percentages of injuries. The difference among various sports in the percentages of injured athletes was statistically significant. Running had the lowest percentage of injuries and basketball had the highest percentage. The most frequently injured body regions were the foot and the ankle in basketball, volleyball, soccer, and running, but in wrestling, the knee. These findings suggest that injury rates are associated with the sport rather than sex of player, and the most frequently injured body regions are the lower extremities. Therefore, the muscles of lower extremity should be strengthened to avoid injuries.

    T1DM is very common in Sweden and is positively associated with HLA class II genes. Approximately 89% of the newly diagnosed patients carry the high-risk HLA DR4-DQ8 and DR3-DQ2. The remaining 11% develop T1DM without them. This can be due to involvement of other genes and environmental factors. Natural killer (NK) cells of the innate immune system are important in antiviral and antitumor immunity. They are implicated in the etiology of autoimmune T1DM. Human NK cells express killer cell immunoglobulin-like receptors (KIR) that belong to the polymorphic multigene family in chromosome 19q3.4. They modulate NK cell response by interacting with HLA class I. In addition, polymorphic MICA in HLA class I interacts with non-polymorphic NKG2D receptor on NK cells. We have studied, in addition to HLA-DR and -DQ, genes of the innate immune system MICA and KIR in Latvian patients (n = 98) with T1DM and controls (n = 100). They were genotyped using standard PCR-based typing methods. MICA allele 5 is positively associated with T1DM. KIR2DL2 and KIR2DS2 were both positively associated. Combined association of MICA4 and KIR2DL2 gave an odds ration (OR) of 26.7. However, the combined risk of KIR2DL2 and HLA class II genes, HLADR3 (OR = 73.4), DR4 (OR = 66.8), and DR3 and DR4 (OR = 88.3), was higher. The maximum risk was when KIR2DL2, MICA5, and DR3/DR4 were in combination. In conclusion, our results suggest that a balance between innate and acquired immunity is important, and an imbalance coud lead to T1DM.

    ABSTRACT Nature has evolved a beautiful design for small-scale vibratory rate-gyro in the form of dipteran halteres that detect body rotations via Coriolis acceleration. In most Diptera, including soldier fly, Hermetia illucens, halteres are a pair of special organs, located in the space between the thorax and the abdomen. The halteres along with their connecting joint with the fly's body constitute a mechanism that is used for muscle-actuated oscillations of the halteres along the actuation direction. These oscillations lead to bending vibrations in the sensing direction (out of the haltere's actuation plane) upon any impressed rotation due to the resulting Coriolis force. This induced vibration is sensed by the sensory organs at the base of the haltere in order to determine the rate of rotation. In this study, we evaluate the boundary conditions and the stiffness of the anesthetized halteres along the actuation and the sensing direction. We take several cross-sectional SEM (scanning electron microscope) images of the soldier fly haltere and construct its three dimensional model to get the mass properties. Based on these measurements, we estimate the natural frequency along both actuation and sensing directions, propose a finite element model of the haltere's joint mechanism, and discuss the significance of the haltere's asymmetric cross-section. The estimated natural frequency along the actuation direction is within the range of the haltere's flapping frequency. However, the natural frequency along the sensing direction is roughly double the haltere's flapping frequency that provides a large bandwidth for sensing the rate of rotation to the soldier flies.

    Aims Since 1956, more than 100,000 Swedish soldiers have served abroad on various international missions. The aim of this paper was to determine whether there was a connection between military service abroad and sleep disorders among Swedish soldiers. Methods The prevalence of sleep disturbances among 1,080 veterans from Kosovo and Afghanistan was compared with almost 27,000 Swedes from a general population sample, using propensity score matching and logistic regression. The sleep disturbances studied were habitual snoring, difficulty inducing sleep (DIS), difficulty maintaining sleep (DMS), early morning awakenings (EMA), and excessive daytime sleepiness (EDS). Insomnia was defined as having at least one of DIS, DMS, or EMA. The covariates used in the matching and adjustments were age, gender, smoking habits, BMI, education, ever having had asthma, moist snuff, and exercise habits. Results The veterans had a significantly lower prevalence of insomnia (26.2% versus 30.4%) and EDS (22.7% versus 29.4%) compared with a matched group from the reference population, using propensity score matching. Analyses with logistic regression showed that belonging to the military population was related to a lower risk of having DMS (adjusted OR (95% CI) 0.77 (0.64–0.91)), insomnia (OR 0.82 (0.71–0.95)), and EDS (OR 0.74 (0.63–0.86)), whereas no significant difference was found for snoring, DIS, and EMA. Conclusion Swedish veterans have fewer problems with insomnia and daytime sleepiness than the general Swedish population. The explanation of our findings may be the selection processes involved in becoming a soldier and when sampling personnel for military assignments abroad. PMID:26959327

    Enteropathogenic and indicator bacteria become injured in drinking water with exposure to sublethal levels of various biological, chemical and physical factors. One manifestation of this injury is the inability to grow and form colonies on selective media containing surfactants. The resulting underestimation of indicator bacteria can lead to a false estimation of water potability. m-T7 medium was developed specifically for the recovery of injured coliforms (both "total" and fecal) in drinking water. The m-T7 method was used to survey operating drinking water treatment and distribution systems for the presence of injured coliforms that were undetected with currently used media. The mean recovery with m-Endo LES medium was less than 1/100 ml while it ranged between 6 and 68/100ml with m-T7 agar. The majority of samples giving positive results with m-T7 medium yielded no detectable coliforms with m-Endo LES agar. Over 95% of the coliform bacteria in these samples were injured. Laboratory experiments were also done to ascribe the virulence of injured waterborne pathogens. Enteropathogens including Salmonella typhimurium, Yersinia enterocolitica and Shigella spp. required up to 20 times the chlorine levels to produce the same injury in enterotoxigenic Escherichia coli (ETEC) and nonpathogenic coliforms. Similar results were seen with Y. enterocolitica exposed to copper. The recovery of ETEC was followed by delayed enterotoxin production, both in vitro and in the gut of experimental animals. This indicates that injured waterborne enteropathogenic bacteria can be virulent.

    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.

    Smith, M S; Milton, I; Strand, M R

    2010-12-01

    Polyembryonic encyrtid wasps are parasitoids that have evolved a clonal form of embryogenesis and a caste system where some progeny become reproducing wasps whereas others develop into a sterile soldier caste. Theory based on the biology of Copidosoma floridanum predicts that the primary role of soldier larvae is to mediate conflict over sex ratio, which also favours female-biased soldier production. Other data, however, suggest that female-biased soldier production reflects a developmental constraint. Here, we assessed whether female-biased soldier function by polyembryonic wasps reflects sex-specific adaptation or constraint by conducting comparative studies with Copidosoma bakeri, a species that produces clutch sizes similar to C. floridanum yet rarely produces broods associated with sex ratio conflict. Our results indicate that the oviposition behaviour of adults, development of progeny and function of soldier larvae differ greatly between C. bakeri and C. floridanum. These findings indicate that caste formation and soldier function in polyembryonic encyrtid wasps are regulated by phenotypically plastic traits. Our results further suggest that the primary function of the soldier caste in some species is defence of host resources from competitors whereas in others it is the resolution of sex ratio conflict.

    A 24-year-old active duty soldier was evacuated from Afghanistan to the United States after persistent upper respiratory tract infection. His course was complicated by an exfoliative rash, diffuse muscle aches, and elevated creatine kinase following trimethoprim-sulfamethoxazole exposure that persisted despite withdrawal of the medication. Dermatomyositis was strongly considered, but the patient had a negative muscle biopsy and had positive serologies for acute Epstein-Barr virus infection. We present a case of acute Epstein-Barr virus infection and possible trimethoprim-sulfamethoxazole reaction mimicking dermatomyositis. PMID:24491625

    Data on 7,424 soldier spouse abuse offenders were analyzed to determine the prevalence of substance use during abusive incidents, and to examine differences between substance-using and non-substance-using offenders. Results showed that 25% of all offenders used substances during abusive incidents, with males and non-Hispanic Whites being more likely to hav e used substances. Substance-using offenders were more likely to perpetrate physical spouse abuse and more severe spouse abuse. These findings underscore the importance of educating military personnel (including commanders) about links between substance use and domestic violence, and of coordinating preventive and therapeutic substance abuse and violence-related interventions.

    Psychology responded to the national needs in World War I and World War II and was itself transformed. National need calls a third time: unprecedented levels of posttraumatic stress disorder, depression, suicide, and anxiety along with a need for a resilient Army capable of meeting the persistent warfare of the foreseeable future. As a large part of the Comprehensive Soldier Fitness program, positive psychology is meeting this need with new tests, with new fitness courses, and with resilience training. These developments may transform the practice of psychology and psychology's relation to medicine and education.

    Hereditary cutaneous melanoma is associated with mutations in the high-risk CDKN2A gene in about 40% of melanoma-prone families. Mutations in the CDK4 gene are the cause in only a few pedigrees. In this study, we analyzed 20 Latvian familial melanoma probands and carried out a comprehensive analysis of CDKN2A including sequencing of its promoter/intronic regions and deletion screening. We also analyzed the critical second exon of the CDK4 gene. One novel intronic variant (IVS2+82C>T) of the CDKN2A gene and a small deletion (c.-20677_-20682delGTACGC) in its promoter region were found. Genotyping of the novel variants in larger melanoma and control groups indicated that the deletion increases the risk of melanoma (odds ratio=6.353, 95% confidence interval: 1.34-30.22, P=0.0168). The CDK4 gene analysis showed a Latvian melanoma family with the mutation R24H carried on the same haplotype as in two previously described Latvian CDK4-positive families. Our study suggests that the main risk gene in Latvian families with a strong family history of melanoma is CDK4 and that most of the other cases analyzed could be sporadic or associated with low-penetrance risk genes.

    Background It is well-known that exposure to combat puts individuals at risk for developing adverse psychological problems, including posttraumatic stress disorder (PTSD), depression, anxiety, and health-related behaviour problems and that the presence of combat-related injury increases the risk for psychopathology. Little is known, however, about the consequences of combat among conscripted soldiers fighting against terrorism in their homeland. Objective The main aim of the current study was to examine the prevalence of probable PTSD, severity of PTSD symptoms, depression, anxiety, and PTSD-related functional impairment among Turkish combat-injured, non-professional veterans. In addition, investigated were also the possible differences among the symptoms of PTSD, depression, and anxiety of the veterans by the frequency of current cigarette and alcohol use. Methods A total of 366 male veterans were assessed by using a demographic information form, which obtained information about injury status and health behaviours, the Posttraumatic Stress Diagnostic Scale (PDS), and the Brief Symptom Inventory (BSI). Symptom frequency and multivariate analysis of variances (MANOVA) were used to analyse the data. Results The prevalence of probable PTSD was 46.7% (171) among Turkish veterans while 16.4% experienced severe depression and 18% experienced severe anxiety. “Upset at reminders (65.8%)” was the most common PTSD symptom. “Responsibilities related to home (48.4%)” was the most frequently reported PTSD-related functional impairment. Results indicated that veterans who smoke more than half a pack per day scored significantly higher in severity of PTSD symptoms, depression, and anxiety. Contrary to expectations, there was no significant difference in symptoms of PTSD, depression, and anxiety related to the frequency of current alcohol use. Conclusion Turkish non-professional veterans with physical injuries have serious psychiatric problems an average of 13 years after

    This cross-sectional study was carried out to investigate the frequency of consanguineous marriage in a group of army conscripts in Ankara and the factors affecting this. Of 4153 soldiers, 387 were married. The rate of marriage between first cousins was found to be 19.1%, and the overall rate of consanguineous marriage was 24.1%. Consanguineous marriage was found to be significantly prevalent among soldiers who were born in and still living in the Eastern region; among those who lived in villages; among those whose parents as well as themselves had low educational levels; and among those whose marriages were arranged by their families. Neither the payment of bride-price nor the presence of consanguinity between parents was a significant factor for consanguineous marriage. In addition, the age of the soldier and the age at marriage were significantly lower among soldiers married to first cousins than among soldiers whose marriages were not consanguineous.

    Operation Enduring Freedom conducted in the high mountains of Afghanistan posed new challenges for U.S. and coalition forces. The high mountains with elevations up to 25,000 feet and little to no road access limited the use of combat vehicles and some advanced weaponry. Small unit actions became the norm and soldiers experienced the effect of high elevation, where limited oxygen and its debilitating effects negatively impacted unacclimated soldiers. While the effects of high altitude on unacclimated soldiers are well documented, the results of those effects in a combat setting are not as well known. For this study, the authors focused on 3 areas: movement speed, response time, and judgment; used a state-of-the-art constructive modeling and simulation (M&S) tool; simulated a combat engagement with less capable unacclimated and fully capable acclimated soldiers; and captured the results, which scaled increased casualties for unacclimated and decreased casualties for acclimated soldiers.

    A U.S. Army Special Forces (SF) unit was studied to determine characteristics of supplement users, assess nutrition knowledge, and identify nutrition information sources. SF-qualified (n = 119) and non-SF, support soldiers (n = 38) participated. Most soldiers (87%) reported current supplement use with more SF (90%) than non-SF, support soldiers (76%) using supplements (p < or = 0.05). Supplements SF reported using most were multivitamins, sports bars/drinks, and vitamin C. The mean nutrition knowledge score for all soldiers was 48.5 +/- 15.2% correct responses. Most soldiers incorrectly believe protein is used for energy for short-term athletic events (64%) and that vitamins provide energy (58%). The most common information sources reportedly used were popular magazines/books (75%), friends/teammates (55%), physicians/nurses, radio/television (34%), and the Internet (31%). PMID:14719624

    Currently existing acoustic based Gunfire Detection Systems (GDS) such as soldier wearable, vehicle mounted, and fixed site devices provide enemy detection and localization capabilities to the user. However, the solution to the problem of portability versus performance tradeoff remains elusive. The Data Fusion Module (DFM), described herein, is a sensor/platform agnostic software supplemental tool that addresses this tradeoff problem by leveraging existing soldier networks to enhance GDS performance across a Tactical Combat Unit (TCU). The DFM software enhances performance by leveraging all available acoustic GDS information across the TCU synergistically to calculate highly accurate solutions more consistently than any individual GDS in the TCU. The networked sensor architecture provides additional capabilities addressing the multiple shooter/fire-fight problems in addition to sniper detection/localization. The addition of the fusion solution to the overall Size, Weight and Power & Cost (SWaP&C) is zero to negligible. At the end of the first-year effort, the DFM integrated sensor network's performance was impressive showing improvements upwards of 50% in comparison to a single sensor solution. Further improvements are expected when the networked sensor architecture created in this effort is fully exploited.

    Caste polyphenism in social insects is regulated by social interactions among colony members. Trophallaxis is one of the most frequently observed interactions, but no studies have been conducted identifying the intrinsic factors involved in this behaviour and caste differentiation. Dopamine (DA) has multiple roles in the modulation of behaviours and physiology, and it produces species-specific behaviours in animals. Here, to verify the role of DA in termite soldier differentiation, we focused on the first soldier in an incipient colony of Zootermopsis nevadensis, which always differentiates from the oldest 3rd instar (No. 1 larva) via a presoldier. First, brain DA levels of the No. 1 larva at day 3 after its appearance were significantly higher than day 0. Second, DA synthesis gene expression levels were extraordinarily high in the No. 1 larva at day 0–1 after appearance. Finally, injection of a DA receptor antagonist into the No. 1 larva resulted in the inhibition of presoldier differentiation. Behavioural observations of the antagonist or control-injected larvae suggested that brain DA and signalling activity regulate the frequencies of trophallaxis from reproductives and presoldier differentiation. Because trophallaxis is a social behaviour frequently observed in natural conditions, the role of DA should be investigated in other social insects with frequent trophallactic and allogrooming behaviour.

    The military has identified Human Performance Modeling (HPM) as a significant requirement and challenge of future systems modeling and analysis initiatives as can be seen in the Department of Defense's (DoD) Defense Modeling and Simulation Office's (DMSO) Master Plan (DoD 5000.59-P 1995). To this goal, the military is currently spending millions of dollars on programs devoted to HPM in various military contexts. Examples include the Human Performance Modeling Integration (HPMI) program within the Air Force Research Laboratory, which focuses on integrating HPMs with constructive models of systems (e.g. cockpit simulations) and the Navy's Human Performance Center (HPC) established in September 2003. Nearly all of these initiatives focus on the interface between humans and a single system. This is insufficient in the era of highly complex network centric SoS. This report presents research and development in the area of HPM in a system-of-systems (SoS). Specifically, this report addresses modeling soldier fatigue and the potential impacts soldier fatigue can have on SoS performance.

    This paper describes the development of unobtrusive room sensors to discover relationships between sleep quality and the clinical assessments of combat soldiers suffering from post-traumatic stress disorder (PTSD) and mild traumatic brain injury (TBI). We consider the use of a remote room sensor unit composed of a Doppler radar, light, sound and other room environment sensors. We also employ an actigraphy watch. We discuss sensor implementation, radar data analytics and preliminary results using real data from a Warrior Transition Battalion located in Fort Gordon, GA. Two radar analytical approaches are developed and compared against the actigraphy watch estimates--one, emphasizing system knowledge; and the other, clustering on several radar signal features. The radar analytic algorithms are able to estimate sleep periods, signal absence and restlessness in the bed. In our test cases, the radar estimates are shown to agree with the actigraphy watch. PTSD and mild-TBI soldiers do often show signs of sporadic and restless sleep. Ongoing research results are expected to provide further insight. PMID:23366346

    The black soldier fly, Heretia illucens (L.), is a nonpest tropical and warm-temperate region insect that is useful for managing large concentrations of animal manure and other biosolids. Manure management relying on wild fly oviposition has been successful in several studies. However, confidence in this robust natural system was low and biological studies were hampered by the lack of a dependable source of eggs and larvae. Larvae had been reared easily by earlier investigators, but achieving mating had been problematic. We achieved mating reliably in a 2 by 2 by 4-m screen cage in a 7 by 9 by 5-m greenhouse where sunlight and adequate space for aerial mating were available. Mating occurred during the shortest days of winter if the sun was not obscured by clouds. Adults were provided with water, but no food was required. Techniques for egg collection and larval rearing are given. Larvae were fed a moist mixture of wheat bran, corn meal, and alfalfa meal. This culture has been maintained for 3 yr. Maintainance of a black soldier fly laboratory colony will allow for development of manure management systems in fully enclosed animal housing and in colder regions.

    Septic sacroiliitis is an uncommon infection of immunocompetent patients, typically caused by gram-positive bacteria, with fewer gram-negative cases, and only 5% attributed to Pseudomonas species. We present a healthy soldier with the first reported case of Pseudomonas fluorescens septic sacroiliitis and discuss unique diagnostic and management issues. Because of its rare incidence and nonspecific presentation, septic sacroiliitis is often unrecognized, and its diagnosis is often delayed. Increased awareness of septic sacroiliitis as a potential disease process in the differential diagnosis of troops presenting with a combination of fever, low-back pain, and weight-bearing difficulty is important. As the young age and trauma exposure of the military population represent a prime demographic for this often unrecognized infection, delayed diagnosis can negatively impact a soldier's military readiness. P. fluorescens is itself a rare pathogen and often misidentified in the laboratory. Enhanced microbiological diagnostic techniques beyond routine culture and susceptibility testing should also be considered to account for less commonly seen pathogens. Although optimal antimicrobial treatment duration for infectious sacroiliitis is not well established, this case shows the early efficacy of oral antibiotics.

    2012-04-01

    A large number of biodegradable byproducts including alcohols, soluble saccharides, volatile organic acids, and amines accumulate in the liquid fraction (leachate) produced as vegetal and food scrap waste decomposes. Untreated leachate, because it is rich in nutrients and organic byproducts, has a high chemical oxygen demand and is normally cleared of soluble organic byproducts by mineralization before its discharge into waterways. Mineralizing leachates using chemical and microbial biotechnologies is, however, a lengthy and costly process. We report here that the larvae of the black soldier fly Hermetia illucens (L.) (Diptera: Stratiomyidae), an insect rich in protein and lipids, and having significant commercial value, while feeding and growing off of compost leachate, lowers its chemical oxygen demand relative to that of leachate unexposed to larvae, neutralizes its acidity, and clears it of volatile organic acids, amines, and alcohols. These observations demonstrate that black soldier fly larvae could be used to help offset the cost and clean up of organic solutes in leachate waste streams while recycling carbon, nitrogen, and phosphate into usable and commercially valuable biomass.

    This paper investigates patterns of socioeconomic difference in the wartime morbidity and mortality of black Union Army soldiers. Among the factors that contributed to a lower probability of contracting and dying from diseases were (1) lighter skin color, (2) a non-field occupation, (3) residence on a large plantation, and (4) residence in a rural area prior to enlistment. Patterns of disease-specific mortality and timing of death suggest that the differences in the development of immunity against diseases and in nutritional status prior to enlistment were responsible for the observed socioeconomic differences in wartime health. For example, the advantages of light-skinned soldiers over dark-skinned and of enlisted men formerly engaged in non-field occupations over field hands resulted from differences in nutritional status. The lower wartime mortality of ex-slaves from large plantations can be explained by their better-developed immunity as well as superior nutritional status. The results of this paper suggest that there were substantial disparities in the health of the slave population on the eve of the Civil War. PMID:22933827

    2012-06-01

    During recent military conflicts, as well as for security interventions, the urban zone has taken a preponderant place. Studies have been initiated in national and in international programs to stimulate the technical innovations for these specific scenarios. For example joint field experiments have been organized by the NATO group SET-142 to evaluate the capability for the detection and localization of snipers, mortars or artillery guns using acoustic devices. Another important operational need corresponds to the protection of military sites or buildings. In this context, unattended acoustic and seismic sensors are envisaged to contribute to the survey of specific points by the detection of approaching enemy soldiers. This paper describes some measurements done in an anechoic chamber and in free field to characterize typical sounds generated by the soldier activities (walking, crawling, weapon handling, radio communication, clothing noises...). Footstep, speech and some specific impulsive sounds are detectable at various distances from the source. Such detection algorithms may be easily merged with the existing weapon firing detection algorithms to provide a more generic "battlefield acoustic" early warning system. Results obtained in various conditions (grassy terrain, gravel path, road, forest) will be presented. A method to extrapolate the distances of detection has been developed, based on an acoustic propagation model and applied to the laboratory measurements.

    Environmental conditions cause neuroses and symptoms of personality disorders in regular soldiers. Military service in highly formalized and hierarchical conditions makes it impossible to: express emotions (particularly negative ones), to arrange one's own time, to choose the position and place of work. Another important psychotraumatic factor is excessive load of work and responsibility for the sake of "the service". Psychotherapy is the main part of neurotic and personality disorder therapy in regular soldiers. The social context is the bass for theoretical assumptions of psychotherapy carried out by the authors. Based on the theory of learning, the aims of the applied psychotherapy are: eagerness for the elimination of symptoms and changing the mode of behaviour. Group psychotherapy is carried out in stationary conditions, in groups of 8 to 13 patients, for 8-9 weeks. The applied methods are: debating psychotherapy, interaction-communicative methods, psychodrawing, musicotherapy, choreotherapy and relaxation techniques. As the result of the therapy, about 89% of symptomatic improvement and about 81% of the change of attitude and behaviour were obtained.

    In June 2006, 118 Singaporean soldiers visited Brunei for jungle training for 10 days. Subsequently, two soldiers had severe diarrhoea and were diagnosed with severe hookworm infection. An epidemiological investigation and case-control study was conducted among the 118 soldiers. A survey was administered to determine the exposures predisposing to infection. Laboratory tests included a full blood count and three separate faecal screens via microscopy and culture. All servicemen were treated with one dose of mebendazole, and follow-up screening was performed 3 months later. Of 113 soldiers completing the questionnaire, 43 soldiers (38%) reported gastrointestinal symptoms post deployment, with 33 (29%) complaining of diarrhoea and 29 (26%) of abdominal pain. Eight had an itch or rash, but none were suggestive of cutaneous larva migrans. Of 103 soldiers completing both the questionnaire and with all the laboratory tests, 42 soldiers (41%) had eosinophilia (>0.6x10(9)/l) and 18 (17%) had hookworm infection on microscopy. More than 89% recalled substantial exposure to soil or groundwater, but no exposure was significantly associated with eosinophilia or infection. After adjusting for possible exposures, not wearing footwear during rest periods had a significantly higher odds ratio (2.86) for acquiring hookworm infection or eosinophilia. Helminth infections are common in visitors to rural Asia. As preventing exposure is often difficult, empirical treatment with anthelminthics should be considered in travellers to high risk areas.

    This study investigated the extent to which decisions by coaches and athletic trainers concerning the return of injured athletes to competition were influenced by the player's status and the game situation. Samples were drawn from Oregon high school and Canadian university basketball teams. Coaches and athletic trainers completed a questionnaire in which they decided whether an injured player should be returned to competition. The scenarios included winning, losing, or close games and involved a starter, first substitute, or bench player. Chi-square analyses revealed that coaches made decisions based on both a player's status and the game situation.

    This study investigated the extent to which decisions by coaches and athletic trainers concerning the return of injured athletes to competition were influenced by the player's status and the game situation. Samples were drawn from Oregon high school and Canadian university basketball teams. Coaches and athletic trainers completed a questionnaire in which they decided whether an injured player should be returned to competition. The scenarios included winning, losing, or close games and involved a starter, first substitute, or bench player. Chi-square analyses revealed that coaches made decisions based on both a player's status and the game situation. In contrast, athletic trainers' decisions were not significantly influenced by these variables. Since the role of the coach seemingly makes it difficult to make health related decisions concerning injured players, athletic trainers should be responsible for such decisions.

  2. Perceptions of Supervision Among Injured and Non-Injured Teens Working in the Retail or Service Industry.

    According to the National Institute for Occupational Safety and Health (NIOSH), a teen is injured every 9 minutes at work. Workplace supervision may affect whether teens are injured on the job. Because research on workplace supervision among teens is limited, the objectives of this study were to characterize the perceptions of supervision among injured and non-injured teen workers and assess the characteristics and perceptions of supervisors that may be associated with work-related injuries. In 2011, a cross-sectional survey was conducted among high school students. Teens who worked in retail or service industries (n= 270) were included in the sample. Non-injured teens were more likely to have reported that their supervisors cared about their safety, were helpful, listened well, and ensured that teen workers understood workplace safety. Most teens (70%) did not feel comfortable talking about safety issues with their supervisors. The importance of supervision and how supervisors are perceived in the workplace may be significant in creating a safety culture that leaves a lasting impression.

    The black soldier fly, Hermetia illucens (L.), is thought to colonize corpses 20-30 days postmortem. However, recent observations indicate this might not be true for all cases. Therefore, we conducted a study examining colonization by the black soldier fly and other Diptera on pig carrion in a plowed field in southern Georgia from 20 September through 21 February. Our data indicate black soldier flies could colonize a corpse within the first week after death. Knowing this information could prevent a serious mistake in estimating the time at which a corpse is colonized by this species. This study also represents the first record of Chrysomya rufifacies in Georgia. PMID:15831010

    Posttraumatic Stress Disorder is a diagnosis related to the past. Pre-traumatic stress reactions, as measured by intrusive involuntary images of possible future stressful events and their associated avoidance and increased arousal, have been overlooked in the PTSD literature. Here we introduce a scale that measures pre-traumatic stress reactions providing a clear future-oriented parallel to the posttraumatic stress reactions described in the diagnostic criteria for PTSD. We apply this pre-traumatic stress reactions checklist (PreCL) to Danish soldiers before, during, and after deployment to Afghanistan. The PreCL has good internal consistency and is highly correlated with a standard measure of PTSD symptoms. The PreCL as answered before the soldiers’ deployment significantly predicted level of PTSD symptoms during and after their deployment, while controlling for baseline PTSD symptoms and combat exposure measured during and after deployment. The findings have implications for the conceptualization of PTSD, screening, and treatment. PMID:26366328

    Marshall Space Flight Center mobile communications platform designs for future lunar missions led to improvements to fleets of tactical robots now being deployed by U.S. Army. The Multi-function Agile Remote Control Robot (MARCbot) helps soldiers search out and identify improvised explosive devices. NASA used the MARCbots to test its mobile communications platform, and in working with it, made the robot faster while adding capabilities -- upgrading to a digital camera, encrypting the controllers and video transmission, as well as increasing the range and adding communications abilities. They also simplified the design, providing more plug-and-play sensors and replacing some of the complex electronics with more trouble-free, low-cost components. Applied Geo Technology, a tribally-owned corporation in Choctaw, Mississippi, was given the task of manufacturing the modified robots. The company is now producing 40 units per month, 300 of which have already been deployed overseas.

    Chemoprophylaxis of malaria on the Thai-Cambodian border is difficult due to the high level of drug resistance. Thirteen separate companies of Royal Thai Marine Militia were placed on 250 mg weekly mefloquine chemoprophylaxis from August 1989 to January 1990. A mean number of 722 soldiers received two or more doses of mefloquine per month for the five month study. The medication was well tolerated and compliance averaged 91%. Substantial numbers of prophylaxis breakthroughs were seen which resulted in 3.2 cases of malaria/100 man-months. Sixty-eight falciparum malaria cases were documented in men who had taken at least two mefloquine doses in the previous four weeks. No serious neuropsychiatric reactions occurred. Mefloquine chemoprophylaxis failures exist on the Thai-Cambodian border and are one sign of the spread of mefloquine resistance.

    Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23 days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2 days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1 month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required.

    Heat illness is a recognised risk of military training. The Combat Fitness Test (CFT) has been identified as an activity that has been associated with heat casualties. The aim of this study was to establish whether a heat stress limit could be set for acclimatised soldiers performing the CFT by measuring the group mean rises in core temperature whilst performing the CFT at various environmental temperatures. The study showed that CFTs should not be undertaken when the start or expected end Wet Bulb Globe Test (WBGT) is greater than 25 degrees C if the group mean rise in core temperature is not to exceed 0.6 degree C (95% CI 0.2 degree C to 1 degree C).

    New hallucinogenic drugs of abuse, known generically as "spice" and "bath salts," have become readily available in the United States. Spice is one of many names that refers to a variety of synthetic cannabinoids that act on the body in a way similar to delta-9-tetrahydrocannabinol (THC). A large and complex variety of synthetic cannabinoids, most often cannabicyclohexanol, JWH-018, JWH-073, or HU-210, are used in an attempt to avoid the laws that make cannabis illegal, making synthetic cannabis a designer drug. Bath salts, on the other hand, is one of many names for a group of cathinone-containing hallucinogens that produces sympathomimetic effects in its users. Both have become popular among those seeking chemical euphorias with decreased chance of detection. Consequently, both have become a problem for maintaining mentally fit Soldiers, unit readiness, and morale in the US armed forces.

    During the Civil War, for the first time in medical history, a large number of excellent photographs were taken of many wounded Union and (to a lesser degree) Confederate soldiers by photographers assigned by their doctors or surgeons, or by photographers employed by the Army Medical Museum. The majority of these photographs demonstrating facial, head, and neck wounds have not been published since the Civil War, except for a few minor exceptions [3, 9]. The actual art of printing photographs in medical journals, daily newspapers, and magazines did not even begin until the early 1880s--almost two decades after the Civil War [24]. Any photographs that could be found in certain rare medical and surgical books during and immediately after the War were actually pasted into those books by their printers. PMID:7668176

    Military personnel deployed to Iraq and Afghanistan, from 2004 to the present, has served in a setting of unique environmental conditions. Among these are exposures to burning trash in open air “burn pits” lit on fire with jet fuel JP-8. Depending on trash burned--water bottles, styrofoam trays, medical waste, unexploded munitions, and computers--toxins may be released such as dioxins and n-hexane and benzene. Particulate matter air pollution culminates from these fires and fumes. Additional environmental exposures entail sandstorms (Haboob, Shamal, and Sharqi) which differ in direction and relationship to rain. These wars saw the first use of improvised explosive devices (roadside phosphate bombs),as well as vehicle improvised explosive devices (car bombs), which not only potentially aerosolize metals, but also create shock waves to induce lung injury via blast overpressure. Conventional mortar rounds are also used by Al Qaeda in both Iraq and Afghanistan. Outdoor aeroallergens from date palm trees are prevalent in southern Iraq by the Tigris and Euphrates rivers, while indoor aeroallergen aspergillus predominates during the rainy season. High altitude lung disease may also compound the problem, particularly in Kandahar, Afghanistan. Clinically, soldiers may present with new-onset asthma or fixed airway obstruction. Some have constrictive bronchiolitis and vascular remodeling on open lung biopsy - despite having normal spirometry and chest xrays and CT scans of the chest. Others have been found to have titanium and other metals in the lung (rare in nature). Still others have fulminant biopsy-proven sarcoidiosis. We found DNA probe–positive Mycobacterium Avium Complex in lung from a soldier who had pneumonia, while serving near stagnant water and camels and goats outside Abu Gharib. This review highlights potential exposures, clinical syndromes, and the Denver Working Group recommendations on post-deployment health. PMID:24443711

    The study focuses on sustainability evaluation of an algae-based energy system in Latvia with a holistic and integrated approach of multi-criteria analysis combined with life cycle assessment (including a practical side - biogas yield experiments of locally available algae). The study shows potential for sustainable use of algae in Latvian conditions and thus that algal biomass can be utilized for the production of biogas. The most sustainable and feasible scenario of using algae for biogas energy production foresees the collection of algae biomass from natural water bodies. Important beneficial effects through the use of algae are related to avoiding global warming potential (GWP) and eutrophication impacts. Biogas batch experiments carried out with the local macrophyte C.demersum have shown a methane yield of 554 l CH4/kg VS.

    2001-12-01

    An analysis of multiple species of Australian gall-inducing thrips with soldiers reveals a significant negative correlation between the size of gall produced and the reproductive division of labour. This correlation suggests that the evolution of smaller galls limited the available space and feeding sites for the offspring of female soldiers, and was a major factor that led to the evolution of an altruistic caste in the gall-inducers. We argue that high levels of inbreeding by singly mated foundresses and incestuous mating by her soldier offspring are key to this evolutionary relationship because they make the relatedness of a female soldier to her daughters and sisters approximately equal. Evidence that relatedness plays an important role is strengthened by the observation of outbred multiply mated foundresses and unbiased sex ratio of dispersers in Oncothrips waterhousei, and the inference that both gall volume and skew decreased along this lineage.

    With growing limitations on military resources, including a reduction in the overall size of our military force, the Army must make the most of every soldier in its ranks. The only way to achieve the necessary improvements in human performance with upcoming constraints will be through exploring innovative ways of thinking while implementing the best policies and doctrine that will maintain each soldier's resilience throughout their military career. Moving the Army from a traditional health care system to a system for health is expected to substantially improve and maintain soldier health and performance by focusing on 3 key areas: the Performance Triad (sleep health, physical activity, and nutrition behaviors), Delivery of Health, and Healthy Environments. The implementation of this system for health will not only improve individual soldier's resiliency/capability both throughout and beyond their military careers and benefit Army Medicine as a whole, but could also serve as a successful model for the nation if changes are adopted.

    Background Syphilis, a known major public health issue for soldiers during periods of conflict, is exacerbated in the Democratic Republic of Congo due to widespread sexual violence. However, there has been no previous study to determine the extent of this problem. Therefore, we determined the prevalence of syphilis among young demobilized soldiers. Methods Screening of syphilis using the rapid plasma reagin test and the Treponema pallidum hemagglutination assay was conducted in three transit sites of soldier reintegration in 2005. The Fisher Exact probability test was used to compare results. Results The prevalence of syphilis was found to be 3.4%, with almost equal distribution in respect to sex, location. Conclusion Syphilis continues to be highly prevalent in demobilized child soldiers in Eastern Congo. Syphilis screening tests are recommended. PMID:21896173

    Since many former child soldiers are aging and having children of their own, this study aimed to understand how the effects of trauma are passed to the next generation. In this qualitative study, semistructured interviews, focus groups, and observations were conducted with 25 former child soldiers and 15 matched civilian parents. Analysis used a grounded-theory approach. Trauma may be transmitted from former child soldiers to their offspring via (a) the effect on indero (how to raise a child); (b) severe parental emotional distress; and (c) community effects. Incorporating themes of indero values on how to raise children, the effects of parental posttraumatic stress and depressive symptoms on offspring, and the stigma associated with the families of former child soldiers may provide key areas of intervention in mental healing.

    The purpose of this evaluation was to examine how increasing body armor protection with and without a fighting load impacted soldiers' performance and mobility. Thirteen male soldiers performed one performance (repeated 30-m rushing) and three mobility tasks (walk, walk over and walk under) with three different body armor configurations and an anterior fighting load. Increasing body armor protection, decreased soldier performance, as individual and total 30-m rush times were significantly longer with greater protection. While increasing body armor protection had no impact on mobility, i.e. significant effect on trunk and lower limb biomechanics, during the walk and walk over tasks, greater protection did significantly decrease maximum trunk flexion during the walk under task. Adding fighting load may negatively impact soldier mobility, as greater maximum trunk extension was evident during the walk and walk over tasks, and decreased maximum trunk flexion exhibited during the walk under task with the fighting load.

    Helmets provide soldiers with ballistic and fragmentation protection but impair auditory spatial processing. Missed auditory information can be fatal for a soldier; therefore, helmet design requires compromise between protection and optimal acoustics. Twelve soldiers localised two sound signals presented from six azimuth angles and three levels of elevation presented at two intensity levels and with three background noises. Each participant completed the task while wearing no helmet and with two U.S. Army infantry helmets - the Personnel Armor System for Ground Troops (PASGT) helmet and the Advanced Combat Helmet (ACH). Results showed a significant effect of helmet type on the size of both azimuth and elevation error. The effects of level, background noise, azimuth and elevation were found to be significant. There was no effect of sound signal type. As hypothesised, localisation accuracy was greatest when soldiers did not wear helmet, followed by the ACH. Performance was worst with the PASGT helmet.

    Objectives. We sought to provide additional information about the characteristics of adolescents who were most likely to cause unintentional injury to other people. Methods. In 2008, as part of a randomized survey of high-school students in the Boston Public School system, more than 1800 respondents answered questions about unintentionally causing an injury to someone else in the past year. Results. More than 20% of boys and 13% of girls reported unintentionally injuring another person in the past year. Being male, exercising, participating in organized activities, and having carried a knife were risk factors for unintentionally causing an injury during sports. Using illegal drugs, having friends who are a bad influence, and having carried a knife were risk factors for unintentionally causing an injury not associated with sports. Conclusions. Unintentionally injuring another person is a fairly common event for high-school students. Characteristics differ between adolescents who unintentionally injure others during sports versus those who unintentionally injure others during nonsports activities. Many of the risk factors for causing unintentional injury unrelated to sports are similar to those for intentionally causing injury. PMID:21389291

    Spinal cord-injured clients have many fears and misapprehensions about their sexual functioning. Such misapprehensions can be helped by the counselor's willingness to discuss sexual issues openly. Clients need a clear and accurate picture of the facts, as well as encouragement and support to help them rediscover their sexuality. (Author)

    This study assesses the presence of a number of psychoactive substances, including alcohol, based on blood samples from 840 seriously injured drivers admitted to five selected hospitals located in five different regions of Denmark. The study was a part of the EU 6th framework program DRUID (Driving Under the Influence of Drugs, Alcohol and Medicines). Blood samples were screened for 30 illegal and legal psychoactive substances and metabolites as well as ethanol. Danish legal limits were used to evaluate the frequency of drivers violating the Danish legislation while limit of quantification (LOQ) was used for monitoring positive drivers. Tramadol is not included in the Danish legislation therefore the general cut off, as decided in the DRUID project was used. Overall, ethanol (18%) was the most frequently identified compound (alone or in combination with other drugs) exceeding the legal limit, which is 0.53g/l in Denmark. The percentage of seriously injured drivers testing positive for medicinal drugs at levels above the Danish legal limit was 6.8%. Benzodiazepines and Z-drugs (6.4%) comprised the majority of this group. One or more illegal drugs (primarily amphetamines and cannabis) were found to be above the Danish legal limit in 4.9% of injured drivers. Young men (median age 31 years) were over-represented among injured drivers who violated Danish law for alcohol and drugs. Diazepam (4.4%), tramadol (3.2%), and clonazepam (3.0%) were the medicinal drugs most frequently detected at levels above LOQ, whereas amphetamines (5.4%) (amphetamine [5.2%] and methamphetamine [1.5%]), tetrahydrocannabinol (3.7%), and cocaine (3.3%), including the metabolite benzoylecgonine, were the most frequently detected illegal drugs. A driver could be positive for more than one substance; therefore, percentages are not mutually exclusive. Poly-drug use was observed in 112 (13%) seriously injured drivers. Tramadol was detected above DRUID cutoffs in 2.1% of seriously injured drivers

    The bacterial microbiota from the whole gut of soldier and worker castes of the termite Reticulitermes grassei was isolated and studied. In addition, the 16S rDNA bacterial genes from gut DNA were PCR-amplified using Bacteria-selective primers, and the 16S rDNA amplicons subsequently cloned into Escherichia coli. Sequences of the cloned inserts were then used to determine closest relatives by comparison with published sequences and with sequences from our previous work. The clones were found to be affiliated with the phyla Spirochaetes, Proteobacteria, Firmicutes, Bacteroidetes, Actinobacteria, Synergistetes, Verrucomicrobia, and candidate phyla Termite Group 1 (TG1) and Termite Group 2 (TG2). No significant differences were observed with respect to the relative bacterial abundances between soldier and worker phylotypes. The phylotypes obtained in this study were compared with reported sequences from other termites, especially those of phylotypes related to Spirochaetes, Wolbachia (an Alphaproteobacteria), Actinobacteria, and TG1. Many of the clone phylotypes detected in soldiers grouped with those of workers. Moreover, clones CRgS91 (soldiers) and CRgW68 (workers), both affiliated with 'Endomicrobia', were the same phylotype. Soldiers and workers also seemed to have similar relative protist abundances. Heterotrophic, poly-β-hydroxyalkanoate-accumulating bacteria were isolated from the gut of soldiers and shown to be affiliated with Actinobacteria and Gammaproteobacteria. We noted that Wolbachia was detected in soldiers but not in workers. Overall, the maintenance by soldiers and workers of comparable axial and radial redox gradients in the gut is consistent with the similarities in the prokaryotes and protists comprising their microbiota.

    Previous studies have shown that combat exposures and deployment-related stressors have negative implications on soldiers' postdeployment health and well-being. The current study aimed to examine the individual and combined effects of organizational and social support on the success of soldiers' postdeployment reintegration. In this study, 2,922 U.S. soldiers were surveyed from a brigade combat team at 90-120 days postdeployment, measuring soldiers' perceptions of postdeployment transition home, occupational and social support, stigma and barriers associated with accessing behavioral health care, and previous behavioral health care. Logistic regression analysis indicated that soldiers reporting a positive postdeployment transition home (n = 1,776; 61%) was significantly associated with leadership perceptions, adjusted odds ratio (AOR) = 1.19, 95% confidence interval (CI) [1.02, 1.39], unit cohesion, AOR = 1.29, 95% CI [1.09, 1.53], personal support, AOR = 1.37, 95% CI [1.23, 1.52], perceived levels of stigma, AOR = 0.73, 95% CI [0.65, 0.82] barriers to accessing care, AOR = 0.86, 95% CI [0.76, 0.97], and previously accessing behavioral health care, AOR = 0.34, 95% CI [0.28, 0.43]. These findings suggest redeploying soldiers may benefit from programs aimed at improving self-efficacy and coping through fostering occupational and social support, with special concern taken to reduce stigma and barriers to care across the Army.

    A number of fuel cell systems have been recently developed to meet the U.S. Army's soldier power requirements. The operation and performance of these systems are discussed based on laboratory results and limited soldier evaluation. The systems reviewed are primarily intended for soldier use in an austere environment with minimum access to resupply and vehicular transportation. These applications require high power and energy density sources that are portable (300 W) and wearable (20 W) to minimize the soldier's load burden. Based on soldier field evaluations of portable fuel cell systems, improvements in power density and compatibility with logistical fuels are required to be successfully deployed. For soldier worn applications, a novel chemical hydride system has shown significant advances in power and energy density while maintaining a small form factor. The use of a high energy dense fuel cartridge (800 Wh kg-1) based on AlH3 (Alane) thermolysis, allows a power density of (28 W kg-1) which offers promising weight savings compared to the standard military batteries.

    Escherichia coli labeled with a green fluorescent protein was inoculated into sterile dairy manure at 7.0 log cfu/g. Approximately 125 black soldier fly larvae were placed in manure inoculated and homogenized with E. coli. Manure inoculated with E. coli but without black soldier fly larvae served as the control. For the first experiment, larvae were introduced into 50, 75, 100, or 125 g sterilized dairy manure inoculated and homogenized with E. coli and stored 72 h at 27 degrees C. Black soldier fly larvae significantly reduced E. coli counts in all treatments. However, varying the amount of manure provided the black soldier fly larvae significantly affected their weight gain and their ability to reduce E. coli populations present. For the second experiment, larvae were introduced into 50 g manure inoculated with E. coli and stored for 72 h at 23, 27, 31, or 35 degrees C. Minimal bacterial growth was recorded in the control held at 35 degrees C and was excluded from the analysis. Black soldier fly larvae significantly reduced E. coli counts in manure held at remaining temperatures. Accordingly, temperature significantly influenced the ability of black soldier fly larvae to develop and reduce E. coli counts with greatest suppression occurring at 27 degrees C.

    Black soldier flies, Hermetia illucens L., are a common colonizer of animal wastes. However, all published development data for this species are from studies using artificial diets. This study represents the first examining black soldier fly development on animal wastes. Additionally, this study examined the ability of black soldier fly larvae to reduce dry matter and associated nutrients in manure. Black soldier fly larvae were fed four rates of dairy manure to determine their effects on larval and adult life history traits. Feed rate affected larval and adult development. Those fed less ration daily weighed less than those fed a greater ration. Additionally, larvae provided the least amount of dairy manure took longer to develop to the prepupal stage; however, they needed less time to reach the adult stage. Adults resulting from larvae provided 27 g dairy manure/d lived 3-4 d less than those fed 70 g dairy manure. Percentage survivorship to the prepupal or adult stages did not differ across treatments. Larvae fed 27 g dairy manure daily reduced manure dry matter mass by 58%, whereas those fed 70 g daily reduced dry matter 33%. Black soldier fly larvae were able to reduce available P by 61-70% and N by 30-50% across treatments. Based on results from this study, the black soldier fly could be used to reduce wastes and associated nutrients in confined bovine facilities. PMID:18348791

    Accumulation of organic wastes, especially in livestock facilities, can be a potential pollution issue. The black soldier fly, Hermetia illucens L. (Diptera: Stratiomyidae), can consume a wide range of organic material and has the potential to be used in waste management. In addition, the prepupae stage of this insect can be harvested and used as a valuable nutritious feed for animal livestock. Five waste types with a wide range of organic source matter were specifically chosen to evaluate the consumption and reduction ability of black soldier fly larvae. H. illucens was able to reduce all waste types examined: 1) control poultry feed, 2) pig liver, 3) pig manure, 4) kitchen waste, 5) fruits and vegetables, and 6) rendered fish. Kitchen waste had the greatest mean rate of reduction (consumption by black soldier fly) per day and produced the longest and heaviest black soldier flies. Larvae reared on liver, manure, fruits and vegetables, and fish were approximately the same length and weight as larvae fed the control feed, although some diets produced larvae with a higher nutritional content. The black soldier fly has the ability to consume and reduce organic waste and be utilized as valuable animal feed. Exploration of the potential use of black soldier flies as an agent for waste management on a large-scale system should continue. PMID:26313195

    Defense against enemies is a type of natural selection considered fundamentally equivalent between the sexes. In reality, however, whether males and females differ in defense strategy is unknown. Multiparasitism necessarily leads to the problem of defense for a parasite (parasitoid). The polyembryonic parasitic wasp Copidosoma floridanum is famous for its larval soldiers' ability to kill other parasites. This wasp also exhibits sexual differences not only with regard to the competitive ability of the soldier caste but also with regard to host immune enhancement. Female soldiers are more aggressive than male soldiers, and their numbers increase upon invasion of the host by other parasites. In this report, in vivo and in vitro competition assays were used to test whether females have a toxic humoral factor; if so, then its strength was compared with that of males. We found that females have a toxic factor that is much weaker than that of males. Our results imply sexual complementarity between host humoral toxicity and larval soldiers. We discuss how this sexual complementarity guarantees adaptive advantages for both males and females despite the one-sided killing of male reproductives by larval female soldiers in a mixed-sex brood.

    As part of the Crew-Automated and integration Testbed (CAT) Advanced Technology Objective (ATO), the US Army Tank-automotive and Armaments Research, Development, and Engineering Center (TARDEC) developed crew stations that provided soldiers the ability to control both manned and unmanned vehicles. The crew stations were designed to optimize soldier workload and provide the ability to conduct mission planning, route planning, reconnaissance, surveillance, and target acquisition (RSTA), and fire control capabilities. The crew station software is fully configurable, portable (between crew stations), and interoperable with one another. However, the software architecture was optimized for the specific computing platform utilized by each crew station and user interfaces were hard coded. Current CAT crew station capabilities are required to execute on other crew station configurations as well as handheld devices to meet the needs of expanded soldier roles, including dismounted infantry. TARDEC is currently exploring ways to develop a scalable software architecture that is able to adapt to the physical characteristics of differing computing platforms and devices. In addition, based upon a soldier's role, the software must be able to adapt and optimize the displays based upon individual soldier needs. And finally, the software must be capable of applying a unique style to the presentation of information to the soldier. Future programs require more robust software architectures that take these requirements into account. This paper will describe how scalable software architectures can be designed to address each of these unique requirements.

    IMPORTANCE The suicide rate among US Army soldiers has increased substantially in recent years. OBJECTIVES To estimate the lifetime prevalence and sociodemographic, Army career, and psychiatric predictors of suicidal behaviors among nondeployed US Army soldiers. DESIGN, SETTING, AND PARTICIPANTS A representative cross-sectional survey of 5428 nondeployed soldiers participating in a group self-administered survey. MAIN OUTCOMES AND MEASURES Lifetime suicidal ideation, suicide plans, and suicide attempts. RESULTS The lifetime prevalence estimates of suicidal ideation, suicide plans, and suicide attempts are 13.9%, 5.3%, and 2.4%. Most reported cases (47.0%–58.2%) had pre-enlistment onsets. Pre-enlistment onset rates were lower than in a prior national civilian survey (with imputed/simulated age at enlistment), whereas post-enlistment onsets of ideation and plans were higher, and post-enlistment first attempts were equivalent to civilian rates. Most reported onsets of plans and attempts among ideators (58.3%–63.3%) occur within the year of onset of ideation. Post-enlistment attempts are positively related to being a woman (with an odds ratio [OR] of 3.3 [95% CI, 1.5–7.5]), lower rank (OR = 5.8 [95% CI, 1.8–18.1]), and previously deployed (OR = 2.4–3.7) and are negatively related to being unmarried (OR = 0.1–0.8) and assigned to Special Operations Command (OR = 0.0 [95% CI, 0.0–0.0]). Five mental disorders predict post-enlistment first suicide attempts in multivariate analysis: pre-enlistment panic disorder (OR = 0.1 [95% CI, 0.0–0.8]), pre-enlistment posttraumatic stress disorder (OR = 0.1 [95% CI, 0.0–0.7]), post-enlistment depression (OR = 3.8 [95% CI, 1.2–11.6]), and both pre- and post-enlistment intermittent explosive disorder (OR = 3.7–3.8). Four of these 5 ORs (posttraumatic stress disorder is the exception) predict ideation, whereas only post-enlistment intermittent explosive disorder predicts attempts among ideators. The population

    The purpose of this study was to explore the relationship between job burnout and neuroendocrine indicators in soldiers living in a harsh environment. Three hundred soldiers stationed in the arid desert and 600 in an urban area were recruited. They filled in the Chinese Maslach Burnout Inventory questionnaire. One hundred soldiers were randomly selected from each group to measure their levels of noradrenaline, serotonin, heat shock protein (HSP)-70, adrenocorticotropic hormone, and serum cortisol. Job burnout was more common in soldiers from urban areas than those from rural areas. Job burnout was significantly higher among soldiers stationed in the arid desert than those in urban areas. For soldiers in the arid desert, the levels of HSP-70, serum cortisol, and adrenocorticotropic hormone were significantly higher than in soldiers in urban areas. Correlation analyses showed that the degree of job burnout was weakly negatively correlated with the level of HSP-70. Being an only child, HSP-70 levels, cortisol levels, and ACTH levels were independently associated with job burnout in soldiers stationed in the arid desert. A higher level of job burnout in soldiers stationed in arid desert and a corresponding change in neuroendocrine indicators indicated a correlation between occupational stress and neurotransmitters.

    This paper presents the Wisconsin Army National Guard's attempt to retain soldiers failing to meet weight and annual physical fitness test standards. Soldiers failing or at risk of failing weight and fitness standards attend a wellness program one weekend per month for three consecutive months. Instruction includes topics in exercise training, nutrition, general wellness, stress reduction, and motivational lectures. A total of 324 soldiers who completed the program were evaluated for retention rates. At 48 months, graduates of the program had a 55% retention rate. This program is cost effective and soldier caring.

    This study examined prevalence and predictors of posttraumatic growth in 180 accidentally injured patients of mainland China in their convalescence stage, investigating its relationships with demographic and accidental injury variables, personality, posttraumatic stress disorder (PTSD) symptoms, and coping styles. Our results showed that posttraumatic growth (PTG) presented mostly in the domain of Relating to Others and indicated that PTG was significantly related to marital status, educational level, personality, coping styles, and PTSD symptoms. Avoidance of PTSD symptoms, Openness to experience, and positive coping were significant predictors of PTG. The findings emphasize that when promoting PTG of accidentally injured patients, healthcare providers should facilitate patients utilizing personal resources, understand PTG coexists with PTSD symptoms, and adjust interventions based on the coping styles the patients have adopted.

    Children represent the most vulnerable members of our global society, a truth that is magnified when they are physically wounded. In much of the developed world, society has responded by offering protection in the form of law, injury prevention guidelines, and effective trauma systems to provide care for the injured child. Much of our world, though, remains afflicted by poverty and a lack of protective measures. As the globe becomes smaller by way of ease of travel and technology, surgeons are increasingly able to meet these children where they live and in doing so offer their hands and voices to care and protect these young ones. This article is intended as an overview of current issues in pediatric trauma care in the developing world as well as to offer some tips for the volunteer surgeon who may be involved in the care of the injured child in a setting of limited resource availability.

    Macrophages in the injured spinal cord arise from resident microglia and from infiltrating peripheral myeloid cells. Microglia respond within minutes after central nervous system (CNS) injury and along with other CNS cells signal the influx of their peripheral counterpart. Although some of the functions they carry out are similar, they appear to be specialized to perform particular roles after CNS injury. Microglia and macrophages are very plastic cells that can change their phenotype drastically in response to in vitro and in vivo conditions. They can change from pro-inflammatory, cytotoxic cells to anti-inflammatory, pro-repair phenotypes. The microenvironment of the injured CNS importantly influences macrophage plasticity. This review discusses the phagocytosis and cytokine-mediated effects on macrophage plasticity in the context of spinal cord injury.

Massive airway and/or lung edema can occur rapidly and unpredictably after burn and/or inhalation injury. Hemodynamics in the early phase of severe burn injury are characterized by a reduction in cardiac output, increased systemic and pulmonary vascular resistance. Approximately 2–5 days after major burn injury, a hyperdynamic and hypermetabolic state develops. Electrical burns result in morbidity much higher than expected based on burn size alone. Formulae for fluid resuscitation should serve only as guideline; fluids should be titrated to physiologic end points. Burn injury is associated basal and procedural pain requiring higher than normal opioid and sedative doses. Operating room concerns for the burn-injured patient include airway abnormalities, impaired lung function, vascular access, deceptively large and rapid blood loss, hypothermia and altered pharmacology.

    We studied US soldiers hospitalized in Korea during 1977 because of acute icteric hepatitis. The clinical characteristics of this illness were similar to those noted in previous studies of this population. In contrast to earlier reports, however, hepatitis B virus was shown to be the single most important cause. Of 139 patients with acute viral hepatitis, 76 (55%) had positive tests for hepatitis B surface antigen (HBsAg) and 63 (45%) were HBsAg-negative on a single determination by radioimmunoassay (AUSRIA II) approximately one week after the onset of symptoms. Nonparenteral transmission was the primary mechanism of hepatitis B infection in this sexually active population. Only one patient had evidence of parenteral drug use. Our increased recognition of hepatitis B virus in these patients can be explained entirely by increased sensitivity of the current radioimmunoassay methods for HBsAg. High rates of nonparenteral transmission of B virus within the populations of developing countries are well recognized. Our findings show that hepatitis B virus can be the major cause of nonparenterally acquired acute hepatitis among foreigners in contact with such a population.

  20. Behavior modeling through CHAOS for simulation of dismounted soldier operations

    One of the major challenges in human behavior modeling for military applications is dealing with all factors that can influence behavior and performance. In a military context, behavior and performance are influenced by the task at hand, the internal (cognitive and physiological) and external (climate, terrain, threat, equipment, etc.) state. Modeling the behavioral effects of all these factors in a centralized manner would lead to a complex rule-base that is difficult to maintain or expand. To better cope with this complexity we have developed the Capability-based Human-performance Architecture for Operational Simulation (CHAOS). CHAOS is a multi-agent system for human behavior modeling that is based on pandemonium theory. Every agent in CHAOS represents a specific part of behavior, such as 'reaction to threat' or 'performing a patrol task'. These agents are competing over a limited set of resources that represent human capabilities. By combining the element of competition with multiple limited resources, CHAOS allows us to model stress, strain and multi-tasking in an intuitive manner. The CHAOS architecture is currently used in firefighter and dismounted soldier simulations and has shown itself to be suitable for human behavior and performance modeling.

    Enteric fever (typhoid and paratyphoid) remains a threat to British troops overseas and causes significant morbidity and mortality. We report the case of a soldier who developed typhoid despite appropriate vaccination and field hygiene measures, which began 23 days after returning from a deployment in Sierra Leone. The incubation period was longer than average, symptoms started 2 days after stopping doxycycline for malaria chemoprophylaxis and initial blood cultures were negative. The Salmonella enterica serovar Typhi eventually isolated was resistant to amoxicillin, co-amoxiclav, co-trimoxazole and nalidixic acid and had reduced susceptibility to ciprofloxacin. He was successfully treated with ceftriaxone followed by azithromycin, but 1 month later he remained fatigued and unable to work. The clinical and laboratory features of enteric fever are non-specific and the diagnosis should be considered in troops returning from an endemic area with a febrile illness. Multiple blood cultures and referral to a specialist unit may be required. PMID:26243802

    Dosage-mortality regressions were determined for black soldier fly, Hermetia illucens (L.), larvae fed cyromazine or pyriproxifen treated media. Cyromazine LC50 for larvae dying before becoming prepupae ranged from 0.25 to 0.28 ppm with dosage-mortality regression slopes between 5.79 and 12.04. Cyromazine LC50s for larvae dying before emergence ranged from 0.13 to 0.19 ppm with dosage-mortality regression slopes between 3.94 and 7.69. Pyriproxifen dosage-mortality regressions were not generated for larvae failing to become prepupae since <32% mortality was recorded at the highest concentration of 1,857 ppm. LC50s for larvae failing to become adults ranged from 0.10 to 0.12 ppm with dosage mortality-regression slopes between 1.67 and 2.32. Lambda-cyhalothrin and permethrin dosage-mortality regressions were determined for wild adult black soldier flies and house flies, Musca domestica L., and for susceptible house flies. Our results indicate that the wild house fly, unlike the black soldier fly, population was highly resistant to each of these pyrethroids. Regression slopes for black soldier flies exposed to lambda-cyhalothrin were twice as steep as those determined for the wild house fly strain. Accordingly, LC50s for the black soldier fly and susceptible house fly were 10- to 30-fold lower than those determined for wild house flies. The differential sensitivity between wild black soldier flies and house flies might be due to behavioral differences. Adult house flies usually remain in animal facilities with the possibility of every adult receiving pesticide exposure, while black soldier fly adults are typically present only during emergence and oviposition thereby limiting their exposure.

    Articular loading is an important factor in the joint degenerative process for individuals with anterior cruciate ligament (ACL) rupture. Evaluation of loading for a population that exhibits neuromuscular compensation for injury requires an approach which can incorporate individual muscle activation strategies in its estimation of muscle forces. The purpose of this study was to evaluate knee joint contact forces for patients with ACL deficiency using an EMG-driven modeling approach to estimate muscle forces. Thirty (30) athletes with acute, unilateral ACL rupture underwent gait analysis after resolving range of motion, effusion, pain and obvious gait impairments. Electromyography was recorded bilaterally from 14 lower extremity muscles and input to a musculoskeletal model for estimation of muscle forces and joint contact forces. Gait mechanics were consistent with previous reports for individuals with ACL-deficiency. Our major finding was that joint loading was altered in the injured limb after acute ACL injury; patients walked with decreased contact force on their injured knee compared to their uninjured knee. Both medial and lateral compartment forces were reduced without a significant change in the distribution of tibiofemoral load between compartments. This is the first study to estimate medial and lateral compartment contact forces in patients with acute ACL rupture using an approach which is sensitive to individual muscle activation patterns. Further work is needed to determine whether this early decreased loading of the injured limb is involved in the development of osteoarthritis in these patients. PMID:23097309

    The purpose of this investigation was to examine the effects of hydraulic resistance exercise training on fitness in spinal cord injured patients. Ten subjects (five quadriplegics and five paraplegics; seven males and three females) participated in a 9-wk training program. Subjects trained 3 times/wk. The 9-wk program was divided into three, 3-wk periods, designated stages I, II, and III. A discontinuous arm crank protocol was used to assess VO2max before and after training. Assessment of the intensity of the hydraulic resistance exercise was made by continuous ECG monitoring during training. A 60 to 90% maximum observed heart rate was calculated for subjects. The spinal cord-injured subjects' VO2max increased 28.1%, and maximum exercise power output increased 36.7% as a result of the 9-wk training program. Both of these findings were statistically significant (P less than 0.01). The exercise intensity was within a 60 to 90% training zone during stages II and III but not during stage I training. The results of this study indicate that hydraulic resistance exercise training may produce increased cardiovascular fitness in spinal cord-injured subjects.

    Introduction Nonsuicidal self-injury (NSSI) is a multifaceted phenomenon and a major health issue among adolescents. A better understanding of self-injury comorbidities is crucial to improve our ability to assess, treat, and prevent NSSI. Purpose This study aimed at analyzing some of the psychobehavioral correlates of NSSI: psychological problems, alexithymia, impulsiveness, and sociorelational aspects. Patients and methods This was a case–control study. The clinical sample (n=33) included adolescents attending our unit for NSSI and other issues; the controls (n=79) were high-school students. Data were collected using six questionnaires: Youth Self-Report, Barratt’s Impulsiveness Scale, Toronto Alexithymia Scale, Children’s Depression Inventory, Symptom Checklist-90-R, and Child Behavior Checklist. Results Cases scored significantly higher in all questionnaires. Habitual self-injurers scored higher on impulsiveness and alexithymia. The gesture’s repetition seems relevant to the global clinical picture: habitual self-injurers appear more likely to seek help from the sociosanitary services. We found a difference between the self-injurers’ and their parents’ awareness of the disorder. Conclusion Habitual self-injurers show signs of having difficulty with assessing the consequences of their actions (nonplanning impulsiveness) and the inability to manage their feelings. Given the significantly higher scores found for cases than for controls on all the psychopathological scales, NSSI can be seen as a cross-category psychiatric disorder, supporting the Diagnostic and Statistical Manual of Mental Disorders decision to include it as a pathological entity in its own right.

    Matrix metalloproteinase-9 is elevated within the acutely injured murine spinal cord and blockade of this early proteolytic activity with GM6001, a broad-spectrum matrix metalloproteinase inhibitor, results in improved recovery after spinal cord injury. As matrix metalloproteinase-9 is likewise acutely elevated in dogs with naturally occurring spinal cord injuries, we evaluated efficacy of GM6001 solubilized in dimethyl sulfoxide in this second species. Safety and pharmacokinetic studies were conducted in naïve dogs. After confirming safety, subsequent pharmacokinetic analyses demonstrated that a 100 mg/kg subcutaneous dose of GM6001 resulted in plasma concentrations that peaked shortly after administration and were sustained for at least 4 days at levels that produced robust in vitro inhibition of matrix metalloproteinase-9. A randomized, blinded, placebo-controlled study was then conducted to assess efficacy of GM6001 given within 48 hours of spinal cord injury. Dogs were enrolled in 3 groups: GM6001 dissolved in dimethyl sulfoxide (n = 35), dimethyl sulfoxide (n = 37), or saline (n = 41). Matrix metalloproteinase activity was increased in the serum of injured dogs and GM6001 reduced this serum protease activity compared to the other two groups. To assess recovery, dogs were a priori stratified into a severely injured group and a mild-to-moderate injured group, using a Modified Frankel Scale. The Texas Spinal Cord Injury Score was then used to assess long-term motor/sensory function. In dogs with severe spinal cord injuries, those treated with saline had a mean motor score of 2 (95% CI 0-4.0) that was significantly (P<0.05; generalized linear model) less than the estimated mean motor score for dogs receiving dimethyl sulfoxide (mean, 5; 95% CI 2.0-8.0) or GM6001 (mean, 5; 95% CI 2.0-8.0). As there was no independent effect of GM6001, we attribute improved neurological outcomes to dimethyl sulfoxide, a pleotropic agent that may target diverse secondary pathogenic

    The social insect soldier is perhaps the most widely known caste, because it often exhibits spectacular weapons, such as highly enlarged jaws or reinforced appendages, which are used to defend the colony against enemies ranging in size from wasps to anteaters. We examined the function of the enlarged forelimbs of soldiers (both male and female) of the eusocial, gall-inhabiting insect Kladothrips intermedius, and discovered that they have little impact on their ability to repel the specialized invading thrips Koptothrips species. While the efficacy of the enlarged forelimb appears equivocal, we show that soldiers secrete strong antifungal compounds capable of controlling the specialized insect fungal pathogen, Cordyceps bassiana. Our data suggest that these thrips soldiers have evolved in response to selection by both macro- and micro-organisms. While it is unknown whether specialized fungal pathogens have been major selective agents in the evolution of the soldier caste in general, they were probably present when sociality first evolved and may have been the primordial enemies of social insects.

    This article presents a case of posttraumatic stress disorder (PTSD) in a 30-year-old soldier of the Polish Military Contingent in Iraq who narrowly escaped death three times. The first time occurred when during a change of guard he was unintentionally shot by his colleague. The projectile penetrated the victim's helmet, slid along its internal shell curvature, and left the shell causing only a scratch on the scalp skin. Another traumatic event was experienced by the soldier a month after the first incident. As a guard of honor, he was "shot" in the same rear head area with a cap of a cream tube, inadvertently stepped on by a colleague. The third event occurred a couple of days later, during a rocket attack on the Diwaniyah base. After this incident the soldier was evacuated to the Clinic of Psychiatry and Combat Stress in Warsaw. Multiform PTSDs that developed in this soldier are described in this work. The course of his comprehensive therapy during his two stays, with a total duration of 8 months, in the clinic is discussed. Also, a detailed description of the therapy controlled exposition to combat stressors in virtual reality (VR), supplemented with behavioral training consisting of desensitization of an aversive reaction to contact with a weapon at a shooting range is presented. The comprehensive treatment activities resulted in full remission of the PTSD symptoms. The soldier continues his service in a logistic support unit.

    Defense against enemies is a type of natural selection considered fundamentally equivalent between the sexes. In reality, however, whether males and females differ in defense strategy is unknown. Multiparasitism necessarily leads to the problem of defense for a parasite (parasitoid). The polyembryonic parasitic wasp Copidosoma floridanum is famous for its larval soldiers’ ability to kill other parasites. This wasp also exhibits sexual differences not only with regard to the competitive ability of the soldier caste but also with regard to host immune enhancement. Female soldiers are more aggressive than male soldiers, and their numbers increase upon invasion of the host by other parasites. In this report, in vivo and in vitro competition assays were used to test whether females have a toxic humoral factor; if so, then its strength was compared with that of males. We found that females have a toxic factor that is much weaker than that of males. Our results imply sexual complementarity between host humoral toxicity and larval soldiers. We discuss how this sexual complementarity guarantees adaptive advantages for both males and females despite the one-sided killing of male reproductives by larval female soldiers in a mixed-sex brood.

    The mission of the Individual Protection Directorate of the U. S. Army Natick Research, Development and Engineering Center is to develop clothing and equipment to protect the individual combat soldier against battlefield chemical, ballistic, surveillance, environmental and nuclear hazards. In an effort to meet our countersurveillance mission, the Terrain Analysis Systn was developed by Natick in conjunction with Decilog, Inc., Melville, New York. The Terrain Analysis System was developed to satisfy the need for a scientific method of designing camouflage patterns based on natural terrain reflectance data. It functions as a portable, abridged spectrophotometer to obtain spectral refltance data in the visible and near-infrared on any scene of interest. Data is collected on videotape in the field, digitized into the computer back in the laboratory, and spectral reflectance factors determined for each pixel in the scene. The 1976 CIE L*a*b* color coordinates are calculated and the image is clustered to a user-specific number of color domains. Camouflage patterns can be designed based on these domains, and visual camouflage evaluations can be made by overlaying the designed patterns on any desired background scene. Additional capabilities include calculation of values analogous to the CIE values, which use infrared film or an image intensifier as the observer. The Terrain Analysis System is also capable of analyzing video data taken through an image intensifier or thermal imager and calculating the probability of detection of a user-defined target against the background. "What if" cases can be run to determine the detection probability under other sets of conditions, such as a detector with a different spectral response or under different atmospheric conditions.

  18. Overview of outcome data of potential meditation training for soldier resilience.

    2011-11-01

    In order to identify potential training to enhance comprehensive soldier fitness, this analysis searched MEDLINE via PubMed and elsewhere for 33 reasonably significant modalities, screening over 11,500 articles for relevance regarding soldier resilience. Evaluation of modalities that are exclusively educational or cognitive/behavioral in nature is deferred. Using the volume and quality of research over 40 parameters distributed among the five domains of resilience (physical, emotional, spiritual, social, and family life), these data allow culling of most of the meditative modalities and discrimination among the remaining techniques. The resulting order of merit is Transcendental Meditation, mindfulness, and progressive muscle relaxation. Transcendental Meditation, mindfulness, and progressive muscle relaxation, in that order, have the most supporting data. Fortuitously, they also represent a cross section of the domain of techniques regarded as meditation, stress management, or relaxation, with three very different mechanisms of action. They are suitable potential options for improving soldier resilience.

    In termites, the soldier caste possesses morphological features suitable for colony defence, despite some exceptions. Soldiers are differentiated via two moultings through a presoldier stage with dramatic morphogenesis. While a number of morphological modifications are known to occur during the presoldier moult, growth and morphogenesis seem to continue even after the moult. The present study, using the damp-wood termite Hodotermopsis sjostedti, carried out morphological and histological investigations on the developmental processes during the presoldier stage that is artificially induced by the application of a juvenile hormone analogue. Measurements of five body parameters indicated that head length significantly increased during the 14-day period after the presoldier moult, while it did not increase subsequently to the stationary moult (pseudergate moult as control). Histological observations also showed that the cuticular development played a role in the presoldier head elongation, suggesting that the soft and flexible presoldier cuticle contributed to the soldier morphogenesis in termites.

    Data from the Total Army Injury and Health Outcomes Database (TAIHOD) were used to describe 28,352 fall-related hospitalizations among active-duty Army soldiers between 1980 and 1998. Soldiers who were younger than age 26, single, and had a high school education or less were at greatest risk. Falls from a height were more likely to be fatal than other types of falls, accounting for 88% of all fatalities. In cases where duty status was known, 64% of the falls took place while the soldier was on duty and half of these occurred during training. The most common type of fall during training was fall from a height (37%). Falls on stairs and ladders accounted for 49% of all off-duty falls.

    Ethylene urea/melamine formaldehyde resin (permanent press) is a common fabric finishing agent added to Army Combat Uniforms for a wrinkle-free appearance and to strengthen the fabric. We describe the case of an active duty U.S. Army soldier with a diffuse eczematous dermatitis in whom patch testing was used to identify an allergy to permanent press, a ubiquitous fabric finishing agent in the Army combat uniform. To our knowledge, this is the first case report of a soldier with an allergic contact dermatitis to ethylene urea/melamine formaldehyde resin. This case highlights the importance of considering the diagnosis of allergic contact dermatitis in patients with a recurrent eczematous dermatitis that does not respond appropriately to therapy and the unique occupational impact of diagnosing an Army soldier with permanent press allergy.

    In termites, the soldier caste possesses morphological features suitable for colony defence, despite some exceptions. Soldiers are differentiated via two moultings through a presoldier stage with dramatic morphogenesis. While a number of morphological modifications are known to occur during the presoldier moult, growth and morphogenesis seem to continue even after the moult. The present study, using the damp-wood termite Hodotermopsis sjostedti, carried out morphological and histological investigations on the developmental processes during the presoldier stage that is artificially induced by the application of a juvenile hormone analogue. Measurements of five body parameters indicated that head length significantly increased during the 14-day period after the presoldier moult, while it did not increase subsequently to the stationary moult (pseudergate moult as control). Histological observations also showed that the cuticular development played a role in the presoldier head elongation, suggesting that the soft and flexible presoldier cuticle contributed to the soldier morphogenesis in termites.

    Bioenergy has become attractive as alternatives of gradually exhausted fossil fuel. Obtaining high grade bioenergy from lignocellulose is attractive that can gradually meet the demand. This study reported biogas and biodiesel were produced from corncob by a two-step bioprocess, biogas was produced from corncob by anaerobic fermentation, then biogas residue was converted by black soldier fly larvae, and then biodiesel was produced from larvae grease. 86.70 L biogas was obtained from 400 g corncob with the accumulation of biogas yield of 220.71 mL/g VS(added) by anaerobic digestion. Besides, 3.17 g of biodiesel was produced from grease after inoculating black soldier fly larvae into 400 g biogas residue. Meanwhile, the results showed that the addition of black soldier fly larvae could be effective for the degradation of lignocellulose and the accumulation of grease.

    A majority of modern war wounds are caused by blasts and high-energy ballistics. Extremity injuries predominate since modern body armor does not protect these areas due to mobility limitations. A less known and more insidious mechanism of enemy attack among our soldiers involves treachery by the local populace posing as noncombatants. One such recent event involved the contamination of tobacco with cyanide (CN). We describe a case of a soldier with CN intoxication due to ingestion of tobacco purchased from a local merchant. The soldier developed a complex neuropathic pain syndrome and was successfully treated with an inpatient high-dose intravenous ketamine infusion in combination with continuous peripheral nerve blockade.

    Unit watch over suicidal patients by nonmedical soldiers is often necessary in a deployed environment, but this strategy's risks may outweigh its benefits in a garrison environment. This case study illustrates risks of unit watches that are difficult for medical personnel to effectively mitigate. The suicidal soldier in question was placed on a unit watch in lieu of psychiatric hospitalization, utilizing a plan agreed upon by all parties. However, within 2 days, the plan had degenerated to an unacceptable degree. A commander is always legally responsible for subordinate soldiers' conduct, but from a patient safety perspective, medical professionals must account for the inevitable periods of decreased oversight within a unit. Medical professionals who recommend a unit watch must consider the risks associated with this course of action, including instances such as the error chain detailed in this case.

  6. The chief seat of mischief: soldier's heart in the First World War.

    2011-04-01

    Soldier's heart was a medico-psychiatric condition that was first documented during the American Civil War. This condition affected British and American soldiers during the late-nineteenth and early-twentieth centuries; doctors recorded patients experiencing palpitations, breathlessness, headaches, and praecordial pain among other symptoms. While the number of cases of this disorder reached its peak in the First World War, it disappeared shortly afterwards. Based on an analysis of experimental results published in generalist and specialized medical journals as well as the correspondence between physicians and researchers that these journals maintained, this study challenges the view that soldier's heart disappeared because doctors realized that the disorder was, in fact, psychosomatic. Instead, this article shows that this notion was an unintentional by-product of the research conducted into the condition, the results of which opposed the somaticist philosophy that many of the researchers had tried to uphold.

    This article presents the multidisciplinary effort in trying to identify the skeletal remains of 100 Norwegian soldiers serving in the German army, killed in Karelia Russia in 1944, from the recovery of the remains through the final identification using DNA. Of the 150 bone samples sent for DNA testing, 93 DNA profiles were obtained relating to 57 unique individuals. The relatives could not be directly contacted as the soldiers were considered as traitors to Norway; therefore, only 45 reference samples, relating to 42 cases of the missing, were donated. DNA matches for 14 soldiers and 12 additional body part re-associations for these individuals were found. Another 24 bone samples were re-associated with 16 individuals, but no familial match was found. More than six decades after the end of WWII, DNA analysis can significantly contribute to the identification of the remains.

    Suicide is the leading cause of soldier death in the Israeli Defense Forces (IDF) in peace time. Suicide attempt (SA) and non-suicidal self-injury (NSSI) are risk factors for death by suicide in civilian studies and therefore their predictive value needs to be determined in the military. All army screening, psychometric and demographic data on consecutive cases of IDF soldier self-harm during the years 2010-2011 were analyzed. The Columbia Suicide Severity Rating Scale was used retrospectively to classify self-harm as suicidal or NSSI. The Suicide Ideation Scale and the Suicide Intent Scale were scored retrospectively by trained clinical psychologists. A total of 107 soldiers reported self-harm during the study period, comprising 70 SA and 37 with NSSI. The most prevalent diagnosis was personality disorder (n = 48). Soldiers with any mood/anxiety disorders comprised the smallest group (n = 21) and included major depression, dysthymia, anxiety, and posttraumatic stress disorder. Soldiers with NSSI (n = 37) did not differ in any of the characteristics from those who attempted suicide (n = 70). Unlike the well-known female dominance in both SA and NSSI patients in other settings, males dominated this army sample in both groups. Soldiers with self-harm (both SA and NSSI) cannot be easily distinguished by any demographics or specific psychological attributes detectable at induction, and the scales used in suicide research cannot predict an attempt or NSSI. Unlike civilian samples, males dominated attempter and NSSI groups and the reason for this may be multifactorial. These retrospective findings, if replicated, indicate the need for different screening strategies at induction into the military.

    The aim of this study was to assess the anthropometrical data and physical fitness of soldiers according to the sociodemographic characteristics during one-year compulsory military service. The height and weight of 197 soldiers were measured at the beginning and at the end of their service, and body mass index was calculated. The physical fitness was evaluated using index of ability on the basis of 2 km walking test. Conscripts from cities were taller than conscripts from rural areas. At the beginning of the service every fifth was overweight (25< or = body mass index <30 kg/m2) or obese (body mass index > or =30 kg/m2): 17.9% of conscripts from rural areas as well as 17.6% from urban were overweight and 1.9% from rural as well as 1.1% from urban areas were obese. A tendency that the weight of conscripts gradually increased with the level of education was observed. There were no significant differences in index of ability according to the level of soldiers' education as well as place of residence. During one-year service the height of soldiers did not change, however, their weight increased in average by 5.5+/-4.5 kg (p<0.01). The part of overweight persons at the end of the service increased 2.3-fold. Physical fitness of soldiers after one-year service significantly decreased compared with the beginning of the service. In order to decrease the rate of overweight soldiers and to increase their physical fitness the health promotion programs in Lithuanian Army are needed.

    Introduction Nonsuicidal self-injury (NSSI) is a multifaceted phenomenon and a major health issue among adolescents. A better understanding of self-injury comorbidities is crucial to improve our ability to assess, treat, and prevent NSSI. Purpose This study aimed at analyzing some of the psychobehavioral correlates of NSSI: psychological problems, alexithymia, impulsiveness, and sociorelational aspects. Patients and methods This was a case–control study. The clinical sample (n=33) included adolescents attending our unit for NSSI and other issues; the controls (n=79) were high-school students. Data were collected using six questionnaires: Youth Self-Report, Barratt’s Impulsiveness Scale, Toronto Alexithymia Scale, Children’s Depression Inventory, Symptom Checklist-90-R, and Child Behavior Checklist. Results Cases scored significantly higher in all questionnaires. Habitual self-injurers scored higher on impulsiveness and alexithymia. The gesture’s repetition seems relevant to the global clinical picture: habitual self-injurers appear more likely to seek help from the sociosanitary services. We found a difference between the self-injurers’ and their parents’ awareness of the disorder. Conclusion Habitual self-injurers show signs of having difficulty with assessing the consequences of their actions (nonplanning impulsiveness) and the inability to manage their feelings. Given the significantly higher scores found for cases than for controls on all the psychopathological scales, NSSI can be seen as a cross-category psychiatric disorder, supporting the Diagnostic and Statistical Manual of Mental Disorders decision to include it as a pathological entity in its own right.

    According with to International Labor Office, the European Union gave the directions to improve the life of workers not only by regulating care, but also safety and return to work. Each European country is conforming to this. In Italy, INAIL, an independent body under the control of the Department of Labor and the Ministry of Health, covers the workers for occupational accidents and is funded by an insurance premium, obligatory paid by the employer. INAIL has the medicolegal task of assessment of injuries, supply of prostheses, physical therapy, and various compensation according to the degree of disability and the type of work. The specific treatment of the injured workers is carried out by the SSN, which is in charge of the outpatient treatment and hospitalization; however, INAIL contributes to the costs according to agreements made with each region. Although on one hand the injured worker is fully protected by the regulations, on the other hand, he or she is obliged to abide to the laws of security and to undergo treatment offered. In returning to work, certain factors are taken into account, such as percentage of disability, type of work, and discomfort that disability produces in carrying out work. Should the type or severity of the disability not allow complete return to work, support is given to assess and integrate the reduced working ability of the injured worker with regards to the workplace, even by adapting the latter to solve structural and environmental problems. INAIL, in accordance with the European Council, is committed to the total care of the worker and not only worker meaning "work force." In fact, health care and economic aid are integrated with the safety and rehabilitation of the worker and his or her return to family, social, and working life.

    The purpose of this study was to explore the optimal timing for surgical intervention of partially injured anterior cruciate ligaments (ACL). Thirty-eight patients were divided into early (n=17) or delayed (n=21) surgery groups based on the interval between injury and surgery. Minimum follow-up was 2 years. The outcome measures used were the International Knee Documentation Committee score, Lysholm knee score, Tegner activity rating, range of motion, and arthrometer measurements. The findings of this study indicate that early surgical reconstruction of partially ruptured ACLs did not result in arthrofibrosis but may prevent secondary loosening of the intact bundles and further meniscal and chondral injury.

    The authors describe the changes occurring in the spinal cord of rats subjected to crush injury of the sciatic nerve followed by low-power laser irradiation of the injured nerve. Such laser treatment of the crushed peripheral nerve has been found to mitigate the degenerative changes in the corresponding neurons of the spinal cord and induce proliferation of neuroglia both in astrocytes and oligodendrocytes. This suggests a higher metabolism in neurons and a better ability for myelin production under the influence of laser treatment.

    Nutritional support of critically ill or injured patients has undergone significant advances in the last few decades. These advances are the direct result of the growing scientific progress and increased knowledge of the biology and biochemistry of key metabolic and nutrient changes induced by injury, sepsis, and other critical illnesses, both in adults and children. As this knowledge has increased, the science of nutritional support has become more disease based and disorder based. This article discusses protein and nitrogen metabolism in critically ill patients, immunomodulation, and the key nutrients involved in an immune-enhancing diet.

    Exploratory research with 293 excombatants who participated as child soldiers in the El Salvador civil war as FMLN (Marti Front for National Liberation) members or as Armed Forces soldiers was conducted to examine their current living conditions and the impact of past military experience. Although nearly ten years have passed since the peace accords were signed, the excombatant exhibited signs of emotional disturbance. Current underprivileged living conditions and social marginalization were decisive factors which inhibited reentry into civilian life and constituted an important psychosocial impact by placing at risk their integration at the family, community and society levels.

    We examined suicidal ideation among 399 active duty Soldiers and Marines engaged in mental health treatment. Using a generalized linear model controlling for demographic and military factors, depression, and positive traumatic brain injury screen, we confirmed our hypothesis that self-report measures of current PTSD symptoms uniquely predicted suicidal ideation. The association between PTSD severity and suicidal ideation was moderated by gender with women at higher risk as PTSD severity increased. Female Soldiers and Marines with high levels of PTSD should receive additional monitoring and intervention. Self-report measures may aid with risk assessment and identify symptom-related distress associated with suicide risk. PMID:27170848

    Wild populations of house flies were inhibited from ovipositing into poultry manure containing larvae of the black soldier fly,Hermetia illucens (L.). A laboratory strain of house fly responded differently, readily ovipositing into manure with lower densities of soldier fly larvae, but avoiding the higher densities tested. The amount of timeH. illucens larvae occupy the manure prior to an oviposition test influences ovipositional responses of house flies. Manure conditioned byH. illucens larvae for 4-5 days did not significantly inhibit house fly oviposition. We suggest that some type of interspecific chemical communication (allomone) is present.

    Insulin-dependent diabetes mellitus (IDDM) is one of the most common chronic diseases. It is an autoimmune, polygenic disease, associated with several genes on different chromosomes. The most important gene is human leukocyte antigen (HLA), also known as major histocompatibility complex (MHC), which is located on chromosome 6p21.3. HLA-DQ8/DR4 and DQ2/DR3 are positively associated with IDDM and DQ6 is negatively associated with IDDM in most Caucasian populations. The MICA gene is located in the MHC class I region and is expressed by monocytes, keratinocytes, and endothelial cells. Sequence determination of the MICA gene identifies 5 alleles with 4, 5, 6, and 9 repetitions of GCT or 5 repetitions of GCT with 1 additional insertion (GGCT), and the alleles are referred to as A4, A5, A5.1, A6, and A9. Analysis of allele distribution among 93 Latvian IDDM patients and 108 healthy controls showed that allele A5 of MICA is significantly increased in IDDM patients [33/93 (35%)] compared to healthy controls [22/108 (20%)] (OR = 2.15; P = 0.016). In conclusion, we believe that MICA may play an important role in the etiopathogenesis of IDDM.

    Killer immunoglobulin-like receptors (KIRs) are known to modulate natural killer (NK) and NK T-cell function by interacting with human leucocyte antigen (HLA) class I ligands on target cells. The aim of our study was to investigate the influence of KIR2D genes with their HLA-C ligands in susceptibility to type 1 diabetes. A total of 98 type 1 diabetes patients and 70 healthy subjects from Latvia were typed for KIR genes and HLA-C ligands using polymerase chain reaction-based genotyping. The HLA C1+/C2+ combination was positively, and C1-/C2+ combination was negatively, associated with type 1 diabetes. Stratification analysis of KIR/HLA-C ligand combinations showed 2DL2+/C1+, 2DL3+/C1+, and 2DS2+ /C1+ to be positively, and 2DL2-/C1- and 2DS2-/ C1- to be negatively, associated. The presence of 2DL2-HLA-C1 in the absence of 2DS1, 2DS2 confers maximum susceptibility. Absence of 2DL2 and HLA-C1 along with absence of 2DS1 and 2DS2 confer maximum protection. A hypothetical model of KIR/ligand combinations on immune responses and type 1 diabetes susceptibility is proposed. Our results suggest that a combination KIR2DL2- HLA-C1 plays a critical role in susceptibility or protection in Latvians against type 1 diabetes.

    Injured nerve terminals of neuromuscular junctions (NMJs) can regenerate. This remarkable and complex response is governed by molecular signals that are exchanged among the cellular components of this synapse: motor axon nerve terminal (MAT), perisynaptic Schwann cells (PSCs), and muscle fiber. The nature of signals that govern MAT regeneration is ill-known. In the present study the spider toxin α-latrotoxin has been used as tool to investigate the mechanisms underlying peripheral neuroregeneration. Indeed this neurotoxin induces an acute, specific, localized and fully reversible damage of the presynaptic nerve terminal, and its action mimics the cascade of events that leads to nerve terminal degeneration in injured patients and in many neurodegenerative conditions. Here we provide evidence of an early release by degenerating neurons of adenosine triphosphate as alarm messenger, that contributes to the activation of a series of intracellular pathways within Schwann cells that are crucial for nerve regeneration: Ca2+, cAMP, ERK1/2, and CREB. These results contribute to define the cross-talk taking place among degenerating nerve terminals and PSCs, involved in the functional recovery of the NMJ. PMID:27242443

    Catecholamine surge after traumatic injury may lead to dysautonomia with increased morbidity. Small retrospective studies have shown potential benefit of beta-blockers (BB) in trauma patients with and without traumatic brain injury (TBI). This study evaluates a large multiply injured cohort without TBI that received BB. Patients were identified from the trauma registry from January 1, 2003 to December 31, 2011. Patients who received >1 dose of BB were compared to controls. Patients with TBI, length of stay (LOS) < 2 days, and prehospital BB were excluded. Outcomes were mortality, intensive care unit (ICU) LOS, and LOS. Stepwise multivariable regression was used to identify variables significantly associated with mortality. During the study period, 19,151 eligible patients were admitted. The mean age was 39 years. Most were male (74%) and most sustained blunt mechanism (75%). A total of 1854 (11%) patients received BB. BB patients had longer LOS (16 vs 6 days), ICU LOS (7 vs 1 days), and higher mortality (2.8 vs 0.5%) (all P < 0.001). Multivariable regression demonstrated no benefit to BB after adjusting for potential confounding characteristics [odds ratio (OR) 0.952; confidence interval (CI) 0.620-1.461]. In conclusion, in this largest study to date, patients receiving BB were older, more severely injured, and had a higher mortality. Unlike TBI patients, multivariable regression showed no benefit from BB in this population.

    This study examined civilian employment among Army National Guard soldiers who had recently returned from Operations Iraqi Freedom (OIF) and Enduring Freedom (OEF). Of specific interest were relationships of re-employment and financial difficulties to several conditions, such as amount of social support during and after deployment, combat exposure, negative feelings during and after deployment, and postdeployment adjustment symptoms. Survey data from the Army's Reintegration Unit Risk Inventory were used (4,546 soldiers in 50 units who were deployed during 2010). Few soldiers reported financial difficulties during deployment (7.1% of the sample) and after having returned (11.8%). Of those who reported postdeployment financial difficulties, nearly one-half had reported such difficulties during deployment, and not having resumed the predeployment job was associated with more postdeployment financial difficulties. Logistic regression analyses showed the relative contribution of the study variables to changed financial status, from deployment to postdeployment. Reported deployment support (e.g., trust in the unit chain-of-command and available support) was associated with decreased financial difficulties. In contrast, increased financial difficulties were associated with having seen others wounded or killed in combat. Other postdeployment experiences, such as feelings of anger and frustration and available support, were associated with increased financial difficulties, in addition to alcohol use, trouble sleeping and suicidal thoughts. Implications of results for policy and practice to lessen financial hardships and job loss associated with deployment are discussed.

    The German Soldier-of-the-Future ("Infanterist der Zukunft" - IdZ) programme provides three different optronic reconnaissance systems and weapon sights respectively for each infantry squad of ten soldiers. Besides the reconnaissance and targeting device (WBBG) of the squad leader and the weapon sight (WBZG) for the sniper, the so-called "Video Visier" (video visor) will be used as a new type of weapon sight for aiming and combating with the German assault rifles G36 and AG36, with the machine gun MG4 as well as with the bazooka PzF3. The video visor includes an uncooled thermal imager, a daylight camera, an eye-safe laser range finder and a digital magnetic compass with inclination sensor. Communication with the soldier-mounted central processing unit and real-time transmission of the video data (e.g. display mounted into the helmet of the soldier) is enabled by a wireless data link. In the presentation of the requirements, the philosophy and concept as well as the functionality of the video visor will be described in detail.

    Adverse social conditions in early life have been linked to increased expression of proinflammatory genes and reduced expression of antiviral genes in circulating immune cells-the conserved transcriptional response to adversity (CTRA). However, it remains unclear whether such effects are specific to the Western, educated, industrialized, rich, and democratic (WEIRD) cultural environments in which previous research has been conducted. To assess the roles of early adversity and individual psychological resilience in immune system gene regulation within a non-WEIRD population, we evaluated CTRA gene-expression profiles in 254 former child soldiers and matched noncombatant civilians 5 y after the People's War in Nepal. CTRA gene expression was up-regulated in former child soldiers. These effects were linked to the degree of experienced trauma and associated distress-that is, posttraumatic stress disorder (PTSD) severity-more than to child soldier status per se. Self-perceived psychological resilience was associated with marked buffering of CTRA activation such that PTSD-affected former child soldiers with high levels of personal resilience showed molecular profiles comparable to those of PTSD-free civilians. These results suggest that CTRA responses to early life adversity are not restricted to WEIRD cultural contexts and they underscore the key role of resilience in determining the molecular impact of adverse environments.

    Background Former child soldiers are at risk of developing post-traumatic stress disorder (PTSD); however, the trajectory of symptoms has yet to be examined. Aims The risk and protective factors associated with PTSD symptom change among former child soldiers in Sierra Leone were investigated. Method Data from 243 former child soldiers (mean age 16.6 years, 30% female) were analysed. Results Self-reported rates of possible PTSD using standard cut-off points declined from 32% to 16% 4 years later (P<0.05). Symptoms of PTSD at baseline were significantly associated with war experiences (P<0.01) and post-conflict family abuse (P<0.001). Reliable improvement in symptoms was reported by 30%. In growth models examining symptom change, worsening of symptoms was associated with death of a parent (P<0.05) and post-conflict stigma (P<0.001). Protective effects were observed for increases in family acceptance (P<0.001). Conclusions The findings indicated improvement in PTSD symptoms among former child soldiers despite limited access to care. Family and community support played a vital part in promoting psychological adjustment. PMID:23887999

    With increasing necessity for intuitive Soldier-robot communication in military operations and advancements in interactive technologies, autonomous robots have transitioned from assistance tools to functional and operational teammates able to service an array of military operations. Despite improvements in gesture and speech recognition technologies, their effectiveness in supporting Soldier-robot communication is still uncertain. The purpose of the present study was to evaluate the performance of gesture and speech interface technologies to facilitate Soldier-robot communication during a spatial-navigation task with an autonomous robot. Gesture and speech semantically based spatial-navigation commands leveraged existing lexicons for visual and verbal communication from the U.S Army field manual for visual signaling and a previously established Squad Level Vocabulary (SLV). Speech commands were recorded by a Lapel microphone and Microsoft Kinect, and classified by commercial off-the-shelf automatic speech recognition (ASR) software. Visual signals were captured and classified using a custom wireless gesture glove and software. Participants in the experiment commanded a robot to complete a simulated ISR mission in a scaled down urban scenario by delivering a sequence of gesture and speech commands, both individually and simultaneously, to the robot. Performance and reliability of gesture and speech hardware interfaces and recognition tools were analyzed and reported. Analysis of experimental results demonstrated the employed gesture technology has significant potential for enabling bidirectional Soldier-robot team dialogue based on the high classification accuracy and minimal training required to perform gesture commands.

  12. Examinations regarding the prevalence of intestinal parasitic diseases in Polish soldiers contingents assigned to missions abroad.

    2011-01-01

    The aim of this paper is to present the program of diagnostic examinations regarding the detection and following treatment of intestinal parasitic diseases in the population of Polish soldiers serving in different climatic and sanitary conditions. Intestinal parasitoses remain one of the health problems of soldiers participating in contemporary military operations. This fact mainly results from unsatisfactory sanitary and hygienic standards in the regions where troops are deployed, contamination of water and soil, inappropriate processes of purifying drinking water, and the terrible condition of sewage systems, water purification plants, or sewage treatment facilities. The occurrence of such diseases is further facilitated by disregard of some basic principles of food and feeding hygiene. Mass examinations of Polish troops to find the prevalence of intestinal parasitoses will cause a decrease in the morbidity rate of parasitic diseases among Polish soldiers deployed in military operations. They can also lead to a decrease in expenditure on medical treatment of disease-related complications and on damages awarded to soldiers who have developed a serious disease while being engaged in a mission abroad.

    2012-01-01

    The present study aimed to evaluate posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems in former Ugandan child soldiers in comparison with civilian children living in the same conflict setting. Participants included 133 former child soldiers and 101 never-abducted children in northern Uganda, who were interviewed about exposure to traumatic war-related experiences, posttraumatic stress symptoms, psychological distress, and emotional and behavioral problems. Results indicated that former child soldiers had experienced significantly more war-related traumatic events than nonabducted children, with 39.3% of girls having been forced to engage in sexual contact. Total scores on measures of PTSD symptoms, psychological distress, and emotional and behavioral problems were significantly higher among child soldiers compared to their never-abducted peers. Girls reported significantly more emotional and behavioral difficulties than boys. In never-abducted children, more mental health problems were associated with experiencing physical harm, witnessing the killings of other people, and being forced to engage in sexual contact.

    2012-09-01

    In 2009, suicide was reported to be the third leading cause of death among U.S. Army personnel. The increase of suicides in the Army indicates the need for additional research to better understand the problem. Research in civilian populations found that experiencing childhood trauma increases the risk for various negative health outcomes, including suicide and suicide attempts, during adulthood. To date, there has been very little focus on pre-existing mental health before joining the service because of a lack of existing data. Participants were active duty Army Soldiers who attempted or completed suicide as identified by the Department of Defense Suicide Event Report. Among Soldiers exhibiting suicidal behavior, analyses were completed to identify significant associations with specific types of childhood trauma experienced before joining the Army. The prevalence of childhood trauma in this population was 43.3% among the suicide cases and 64.7% among the attempt cases. The most common types of childhood trauma among Soldiers were family problems and abuse. The need for further research among military populations is clear given the high prevalence of childhood trauma found among these Soldiers with suicidal behavior and the lack of complete data for this population.

    1997-12-01

    Cold weather injury (CWI) reports covering 272 U.S. Army soldiers from September 1990 to May 1995 were reviewed. First- and second-degree frostbite accounted for 99.3% of all injuries. Although some soldiers had extensive lost duty time from their injuries, no one suffered tissue loss during the 5-year period. Fifty-one percent of injuries occurred during field training. Thirty-six percent occurred while engaging in garrison activities, including physical training, which accounted for 15% of all CWIs. Twelve percent of all injuries occurred during off-duty time. Seventy-one percent of CWIs occurred when the wind-chill factor was at or below -20 degrees F (-29 degrees C). Male African-American soldiers appear to be significantly more susceptible to frostbite than male Caucasian soldiers, especially with regard to frostbite of the distal extremities (relative risk = 3.94; 95% confidence interval = 2.77-5.59). Other identified risk factors include inadequate clothing, wet clothing, dehydration, inactivity, fatigue, and previous CWIs.

    In order to best tailor suicide prevention initiatives and programs, it is critical to gain an understanding of how service members׳ suicide risk factors may differ by gender. We aimed to better understand gender differences in suicide and suicide attempts among soldiers, including demographic, military, mental health, and other risk factors. We also examined risk factors uniquely associated with suicide and suicide attempts. We conducted a retrospective study of 1857 US Army soldiers who died by suicide or attempted suicide between 2008 and 2010 and had a Department of Defense Suicide Event Report. Female and male soldiers had more similarities than differences when examining risk factors associated with suicide. The only gender difference approaching significance was workplace difficulties, which was more strongly associated with suicide for female soldiers, compared to their male counterparts. Among suicide decedents, the most common risk factor was having a failed intimate relationship in the 90 days prior to suicide. Among those who attempted suicide, the most common risk factor was a major psychiatric diagnosis. Better understanding both gender differences and risk factors uniquely associated with suicide has critical prevention and public health implications as we work to better understand preventable mortality in our youngest generation of service members.

  7. Physiological and Medical Aspects That Put Women Soldiers at Increased Risk for Overuse Injuries.

    PubMed

    Epstein, Yoram; Fleischmann, Chen; Yanovich, Ran; Heled, Yuval

    2015-11-01

    Anthropometric and physiological factors place female soldiers at a disadvantage relative to male soldiers in most aspects of physical performance. Average aerobic and anaerobic fitness levels are lower in women than in men. Thus, women have a lower overall work capacity and must exert themselves more than men to achieve the same output. The lower weight and fat-free mass and the higher body fat of women are associated with lower muscle strength and endurance, placing them at a disadvantage compared with men in performing military tasks such as lifting and carrying weights, or marching with a load. Working at a higher percentage of their maximal capacity to achieve the same performance levels as men, women tire earlier. Their smaller size, skeletal anatomy, and different bone geometry also predispose women to a higher incidence of exercise-related injuries. Consequently, the attrition rate of female soldiers in combat units is higher than that of their male counterparts. This review summarizes the literature on gender-related physiological and anatomical differences that put female soldiers at an increased risk of exercise-related injuries. PMID:26506172

    2001-09-01

    Sensors and computational capability have not reached the point to enable small robots to navigate autonomously in unconstrained outdoor environments at tactically useful speeds. This problem is greatly reduced, however, if a soldier can lead the robot through terrain that he knows it can traverse. An application of this concept is a small pack-mule robot that follows a foot soldier over outdoor terrain. The solder would be responsible to avoid situations beyond the robot's limitations when encountered. Having learned the route, the robot could autonomously retrace the path carrying supplies and munitions. This would greatly reduce the soldier's workload under normal conditions. This paper presents a description of a developmental robot sensor system using low-cost commercial 3D vision and inertial sensors to address this application. The robot moves at fast walking speed and requires only short-range perception to accomplish its task. 3D-feature information is recorded on a composite route map that the robot uses to negotiate its local environment and retrace the path taught by the soldier leader.

    Tucker, Jennifer S; Sinclair, Robert R; Mohr, Cynthia D; Thomas, Jeffrey L; Salvi, Angela D; Adler, Amy B

    2009-07-01

    Cognitive Resource Theory (CRT) suggests that under high levels of stress, employees are more prone to committing indiscipline. As few studies have examined this relationship over time, the authors conducted a six-wave longitudinal study examining the relationship of soldiers' indiscipline with work demands and control. The study included archival data collected quarterly over 2 years from 1,701 soldiers representing 10 units in garrison (Germany and Italy), in training rotations (Grafenwoehr, Germany), and on peacekeeping deployments (Kosovo, Kuwait). No main effects were found for work overload, and the findings for the moderating effects of control were contradictory. Within each time point, as work overload increased, soldiers who felt less control committed more indiscipline, supporting CRT. Over time, however, as work overload increased, soldiers who perceived less control 6 months earlier committed less indiscipline. Additionally, the authors found reverse causal effects for control such that prior perceptions of a lack of control were associated with indiscipline and prior incidents of indiscipline with less control.

    Psychotrauma occurs as a result to a traumatic event, which may involve witnessing someone's actual death or personally experiencing serious physical injury, assault, rape and sexual abuse, being held as a hostage, or a threat to physical or psychological integrity. Post-traumatic stress disorder (PTSD) is an anxiety disorder and was defined in the past as railway spine, traumatic war neurosis, stress syndrome, shell shock, battle fatigue, combat fatigue, or post-traumatic stress syndrome (PTSS). If untreated, post-traumatic stress disorder can impair relationships of those affected and strain their families and society. Deployed soldiers are especially at a high risk to be affected by PTSD but often receive inadequate treatment. Reviews to date have focused only on a single type of treatment or groups of soldiers from only one country. The aim of the current review was to evaluate characteristics of therapeutic methods used internationally to treat male soldiers' PTSD after peacekeeping operations in South Eastern Europe and the Gulf wars.This systematic literature review returned results pertaining to the symptoms, diagnosis, timing and effectiveness of treatment. Sample groups and controls were relatively small and, therefore, the results lack generalizability. Further research is needed to understand the influence and unique psychological requirements of each specific military operation on the internationally deployed soldiers. PMID:19643016

    2003-04-01

    The present research examined whether self engagement moderated the stressor-strain relationship in a sample of U.S. soldiers deployed on a peacekeeping mission to Bosnia. Given that individuals were nested within groups (Army companies), we examined the relationships of interest using multilevel random coefficient models. The results of these analyses revealed that self engagement interacted with three different stressors (lower amounts of sleep, work stress, family stress) in the prediction of psychological distress. In support of self engagement as a buffer against stress, when stressors were low (high amounts of sleep, low levels of work stress, and family stress), soldiers reported relatively low levels of psychological distress and physical symptoms, regardless of whether they were engaged in or disengaged from their job. However, when stressor levels were high, soldiers who were engaged in their job reported less elevation in reports of psychological distress than soldiers who were disengaged from their job. The results are discussed in terms of the potential mechanisms by which self engagement might protect individuals from stressful circumstances. PMID:12693517

  2. Evolution of low-profile and lightweight electrical connectors for soldier-worn applications

    NASA Astrophysics Data System (ADS)

    2011-06-01

    In addition to military radios, modern warfighters carry cell phones, GPS devices, computers, and night-vision aids, all of which require electrical cables and connectors for data and power transmission. Currently each electrical device operates via independent cables using conventional cable and connector technology. Conventional cables are stiff and difficult to integrate into a soldier-worn garment. Conventional connectors are tall and heavy, as they were designed to ensure secure connections to bulkhead-type panels, and being tall, represent significant snag-hazards in soldier-worn applications. Physical Optics Corporation has designed a new, lightweight and low-profile electrical connector that is more suitable for body-worn applications and operates much like a standard garment snap. When these connectors are mated, the combined height is <0.3 in. - a significant reduction from the 2.5 in. average height of conventional connectors. Electrical connections can be made with one hand (gloved or bare) and blindly (without looking). Furthermore, POC's connectors are integrated into systems that distribute data or power from a central location on the soldier's vest, reducing the length and weight of the cables necessary to interconnect various mission-critical electronic systems. The result is a lightweight power/data distribution system offering significant advantages over conventional electrical connectors in soldier-worn applications.

    To investigate the irradiation effect of polarization direction and the intensity of a semiconductor laser on the injured peripheral nerve in rabbits, the model of the injured common peroneal nerve was established, the L5,6 spinal segments of the rabbits were irradiated, a uniform rotating polarizer was placed at the laser output which made the polarization direction and intensity of the output laser change according to the 80 Hz cosine law. The experimental results show that irradiating the spinal segment of injured nerves in rabbits with this changeable semiconductor laser can significantly promote the regeneration of injured peripheral nerves and the function recovery.

  8. [The disease and treatment of the frontline soldiers in Han dynasty].

    This paper purports to identify and analyze the medical information of the frontline soldiers in the Northwest borderland provinces of Han Dynasty, especially Juyan and Dunhuang region, through an heuristic reading of the Juyan Bamboo Slips and the Dunhuang Bamboo Slips of the Han Dynasty. My findings are as follows. The most frequent disease found in the bamboo slips was the external injury. The injury of the frontline soldiers mainly occurred from the quarrels among armed soldiers using weapons. The bamboo slips also demonstrate that the quarrels usually arose due to the fierce tension caused by the frontier line service such as heavy guard activity and labour duty. Undernourishment and chronic stress the soldiers suffered might be another reasons. The second most common disease harassing the soldiers was exogenous febrile disease. In most cases reviewed in this paper, the exogenous febrile disease was usually concurrent with complex symptoms such as chills, fever, headache, etc. The bamboo slips show that the exogenous febrile disease was related to the harsh climate of the Northwest provinces, featuring extremely dry weather and the large magnitude of diurnal temperature fluctuations. In addition, the annual temperature range in the Northwest province was huge, fluctuating between very cold and dry winter and very hot and dry summer. The third most common disease this study identified was the disorder of the digestive system and respiratory system. However, these two types of disease were virtually indistinguishable in the bamboo slips, because the ancient Chinese chroniclers did not distinguish them, usually dubbing both diseases simply 'abdominal pain.' It should be mentioned that a few slips mention contagious disease such as dysentery and dermatolosis, and sudden death, as well. Overall, the bamboo slips demonstrate extremely poor status of the soldiers' heath condition and poor medical environment surrounding the soldiers stationing in the Northwest

  9. Remote monitoring of soldier safety through body posture identification using wearable sensor networks

    The physical safety and well being of the soldiers in a battlefield is the highest priority of Incident Commanders. Currently, the ability to track and monitor soldiers rely on visual and verbal communication which can be somewhat limited in scenarios where the soldiers are deployed inside buildings and enclosed areas that are out of visual range of the commanders. Also, the need for being stealth can often prevent a battling soldier to send verbal clues to a commander about his or her physical well being. Sensor technologies can remotely provide various data about the soldiers including physiological monitoring and personal alert safety system functionality. This paper presents a networked sensing solution in which a body area wireless network of multi-modal sensors can monitor the body movement and other physiological parameters for statistical identification of a soldier's body posture, which can then be indicative of the physical conditions and safety alerts of the soldier in question. The specific concept is to leverage on-body proximity sensing and a Hidden Markov Model (HMM) based mechanism that can be applied for stochastic identification of human body postures using a wearable sensor network. The key idea is to collect relative proximity information between wireless sensors that are strategically placed over a subject's body to monitor the relative movements of the body segments, and then to process that using HMM in order to identify the subject's body postures. The key novelty of this approach is a departure from the traditional accelerometry based approaches in which the individual body segment movements, rather than their relative proximity, is used for activity monitoring and posture detection. Through experiments with body mounted sensors we demonstrate that while the accelerometry based approaches can be used for differentiating activity intensive postures such as walking and running, they are not very effective for identification and

    Multiple-choice questionnaires devised to evaluate knowledge and awareness of testicular carcinoma and the practice of testicular self-examination (TSE) were distributed to 717 male soldiers and 200 military physicians in the Israeli army. Twenty-one percent of the soldiers had received explanations about the importance of TSE; 16% actually received instruction on TSE; yet only 2% practiced TSE regularly. Seventy percent of physicians had been taught how to examine testicles, but only 10% of physicians examined testicles in their routine physical exams. TSE was practiced most frequently among soldiers who had received instruction in the technique. Physicians should encourage their young male patients to practice TSE.

  11. Mode of action of air pollutants in injuring horticultural plants

    An attempt has been made to condense the great volume of literature for many different air pollutants and from many different plant systems. Only those responses that have been reported for several species are emphasized and the discussion is limited to responses obtained with intact plants. The general outline provides a focus; uptake becomes the crucial aspect of whether or not plants are injured by air pollutants. Pollutants must get into the plant to cause injury and the primary portal of entry is through the open stomata. Once into the plant, pollutants alter biochemical reactions, resulting in cell injury and causing economic losses for horticulturists. The authors have developed this outline for the pollutants sulfur dioxide (SO/sub 2/), hydrogen fluoride (HF), ozone (O/sub 3/), nitrogen dioxide (NO/sub 2/), and peroxyacetyl nitrate (PAN), which are the most common and and most damaging gaseous pollutants in the ambient environment.

    Among the objectives of spinal cord injury (SCI) rehabilitation, (i) prevention of bony, muscular and joint trophism and (ii) limitation of spastic hypertone represent important goals to be achieved. The aim of this study is to use functional electrical stimulation (FES) to activate pedaling on cycle-ergometer and analyse effects of this technique for a rehabilitation training in SCI persons. Five spinal cord injured subjects were recruited and underwent a two months FES-cycling training. Our results show an increase of thigh muscular area and endurance after the FES-cycling training, without any increase of spasticity. This approach, which is being validated on a larger pool of patients, represents a potential tool for improving the rehabilitation outcome of complete and incomplete SCI persons.

    An important development in behavioral neuroscience in the past 20 years has been the demonstration that it is possible to stimulate functional recovery after cerebral injury in laboratory animals. Rodent models of cerebral injury provide an important tool for developing such rehabilitation programs. The models include analysis at different levels including detailed behavioral paradigms, electrophysiology, neuronal morphology, protein chemistry, and epigenetics. A significant challenge for the next 20 years will be the translation of this work to improve the outcome from brain injury and disease in humans. Our goal in the article will be to synthesize the multidisciplinary laboratory work on brain plasticity and behavior in the injured brain to inform the development of rehabilitation programs.

    Neuropsychology, which deals with the relationships between upper mental functions and brain structures is directly involved with psychiatric and psychological disorders and thus constitutes one of the major domains of cognitive sciences. The impairment of upper mental functions is evident after severe brain injuries causing significant motor deficits. However, it is becoming increasingly evident that even mild or moderate brain injuries can cause sequelae which are difficult to analyze and quantify clinically. These sequelae constitute an "invisible handicap" which may greatly interfere with the patient's professional, relational and social life. The neuropsychological evaluation must be systematic and complete and has to be carried out with a sufficient hindsight (two to three years after the trauma) using neuropsychological and behavioural deficiency evaluation scales. Psychometric tests are also necessary. The data obtained from this evaluation must be correctly interpreted and constitutes the main exhibit in the forensic examination of the brain injured patient.

    Although Schwann cell myelin breakdown is the universal outcome of a remarkably wide range of conditions that cause disease or injury to peripheral nerves, the cellular and molecular mechanisms that make Schwann cell-mediated myelin digestion possible have not been established. We report that Schwann cells degrade myelin after injury by a novel form of selective autophagy, myelinophagy. Autophagy was up-regulated by myelinating Schwann cells after nerve injury, myelin debris was present in autophagosomes, and pharmacological and genetic inhibition of autophagy impaired myelin clearance. Myelinophagy was positively regulated by the Schwann cell JNK/c-Jun pathway, a central regulator of the Schwann cell reprogramming induced by nerve injury. We also present evidence that myelinophagy is defective in the injured central nervous system. These results reveal an important role for inductive autophagy during Wallerian degeneration, and point to potential mechanistic targets for accelerating myelin clearance and improving demyelinating disease.

    With increasing regularity, biomaterials are being designed with the goal of promoting repair of the injured spinal cord. Most often, the efficacy of novel biomaterials is tested using in vitro models; however, their true potential will be realized only after they are applied and evaluated in standardized in vivo spinal cord injury (SCI) models. The purpose of this review is to (1) provide a primer on SCI research including an overview of common pathogenic mechanisms that may respond to biomaterials and the in vivo models and outcomes assessment tools used to evaluate therapeutic efficacy; (2) review the types of biomaterials that have been tested in these models; (3) discuss which biomaterials might be applied to these models in the future; and (4) recommend future engineering strategies to create better in vivo models and assessment tools.

    Fourier transform infrared (FT-IR) spectroscopy was used to differentiate mixed strains of Listeria monocytogenes and mixed strains of L. monocytogenes and Listeria innocua. FT-IR spectroscopy was also applied to investigate the hypothesis that heat-injured and acid-injured cells would return to their original physiological integrity following repair. Thin smears of cells on infrared slides were prepared from cultures for mixed strains of L. monocytogenes, mixed strains of L. monocytogenes and L. innocua, and each individual strain. Heat-injured and acid-injured cells were prepared by exposing harvested cells of L. monocytogenes strain R2-764 to a temperature of 56 ± 0.2°C for 10 min or lactic acid at pH 3 for 60 min, respectively. Cellular repair involved incubating aliquots of acid-injured and heat-injured cells separately in Trypticase soy broth supplemented with 0.6% yeast extract for 22 to 24 h; bacterial thin smears on infrared slides were prepared for each treatment. Spectral collection was done using 250 scans at a resolution of 4 cm(-1) in the mid-infrared wavelength region. Application of multivariate discriminant analysis to the wavelength region from 1,800 to 900 cm(-1) separated the individual L. monocytogenes strains. Mixed strains of L. monocytogenes and L. monocytogenes cocultured with L. innocua were successfully differentiated from the individual strains when the discriminant analysis was applied. Different mixed strains of L. monocytogenes were also successfully separated when the discriminant analysis was applied. A data set for injury and repair analysis resulted in the separation of acid-injured, heat-injured, and intact cells; repaired cells clustered closer to intact cells when the discriminant analysis (1,800 to 600 cm(-1)) was applied. FT-IR spectroscopy can be used for the rapid source tracking of L. monocytogenes strains because it can differentiate between different mixed strains and individual strains of the pathogen.

    In Latvia diabetes mellitus is diagnosed using the WHO's clinical criteria; assays for the detection of autoantibodies are not available, and hence slowly progressive autoimmune diabetes is likely to be missed. Autoantibodies against glutamic acid decarboxylase (GAD65) and protein tyrosine phosphatase (IA-2) among patients with clinically diagnosed NIDDM identify group of patients with slow-onset type 1 diabetes or LADA. The aim of this study was to estimate the risk of polyendocrine autoimmunity among clinically diagnosed NIDDM patients from Latvia. One hundred NIDDM patients and 100 healthy controls were tested for GAD65 and IA-2 autoantibodies as well as 21-hydroxylase (21-OH) and tissue transglutaminase (TTG) antibodies by RIA assay. Age at onset was >or= 30 years, and duration of disease less than 5 years. Of 100 patients, 85 were on oral hypoglycemic agents and 15 were on insulin. Body mass index (BMI) under 19 was recorded in 1% (1 of 100 cases), while overweight (BMI > 25.5 in females and 27 in males) was documented in 45% (45 of 100 cases). GAD65 antibodies were found in 30 of 100 (30%) and IA-2 antibodies in 40 of 100 (40%) patients. Either GAD65 or IA-2 antibodies were found in 55 of 100 (55%). None of the patients carried antibodies against 21-OH and only 1 of 100 (1%) carried antibodies against TTG. From the results obtained in our study we conclude that in Latvian adult NIDDM subjects, islet autoantibodies identify groups of slow-onset type 1 diabetes but not polyendocrine autoimmunity.

    2014-11-01

    Transfer of severely injured patients to regional trauma centers is often expedited; however, transfer of less-injured, older patients may not evoke the same urgency. We examined referring hospitals' length of stay (LOS) and compared the subsequent outcomes in less-injured transfer patients (TP) with patients presenting directly (DP) to the trauma center. We reviewed the medical records of less-injured (Injury Severity Score [ISS] 9 or less), older (age older than 60 years) patients transferred to a regional Level 1 trauma center to determine the referring facility LOS, demographics, and injury information. Outcomes of the TP were then compared with similarly injured DP using local trauma registry data. In 2011, there were 1657 transfers; the referring facility LOS averaged greater than 3 hours. In the less-injured patients (ISS 9 or less), the average referring facility LOS was 3 hours 20 minutes compared with 2 hours 24 minutes in more severely injured patients (ISS 25 or greater, P < 0.05). The mortality was significantly lower in the DP patients (5.8% TP vs 2.6% DP, P = 0.035). Delays in transfer of less-injured, older trauma patients can result in poor outcomes including increased mortality. Geographic challenges do not allow for every patient to be transported directly to a trauma center. As a result, we propose further outreach efforts to identify potential causes for delay and to promote compliance with regional referral guidelines.

    After the reunion between Denmark and Southern Jutland in 1920, the Danish state took over the obligations towards disabled soldiers and surviving relatives to dead soldiers from this province, serving in the German army during World War I. In 1920, the regulations were fixed by law, giving rise to Invalide-noevnet (disabled soldiers' board) in Sonderborg. The board dealt with altogether 6400 applications for invalidity pension and 4000 applications from surviving relatives. In Sonderborg an institution for disabled soldiers (Krigsinvalideskolen) was founded, including a hospital department and workshops for training and rehabilitation as well as production of bandages. A survey is given of these activities. The author next uncovers the story behind one of 9 names on a war memorial tablet, representing soldiers from the parish of Lebol, Sydals, who died in German war service during World War I. The medical record for this dead soldier is given and the family's fruitless efforts for 18 years to obtain pension are reported in details.

    In termites, the soldier caste, with its specialized defensive morphology, is one of the most important characteristics for sociality. Most of the basal termite species have both male and female soldiers, and the soldier sex ratio is almost equal or only slightly biased. However, in the apical lineages (especially family Termitidae), there are many species that have soldiers with strongly biased sex ratio. Generally in termites, since high juvenile hormone (JH) titer is required for soldier differentiation from a worker via a presoldier stage, it was hypothesized that the biased soldier-sex ratio was caused by differences in JH sensitivity and/or JH titer between male and female workers. Therefore, we focused on the presoldier differentiation and the worker JH titer in species with only male soldiers (Nasutitermes takasagoensis) and with both male and female soldiers (Reticulitermes speratus) in natural conditions. In the former species, there are four types of workers; male minor, male medium, female medium and female major workers, and presoldiers differentiate from male minor workers. First, we tried to artificially induce presoldiers from male and female workers. In N. takasagoensis, the presoldier differentiation rate and mortality was significantly higher in male minor workers. Morphological analyses showed that both male and female induced presoldiers possessed normal soldier-specific morphologies. It was suggested that female workers, from which soldiers do not differentiate under natural conditions, also maintained the physiological and developmental potential for soldier differentiation. In R. speratus, however, no differences were observed in solder differentiation rate and mortality between male and female workers. Second, the JH titers of each sex/type of workers were quantified by high performance liquid chromatography-mass spectrometry in two different seasons (April and December). The results showed that, in N. takasagoensis, JH titer in male minor

    National Guard soldiers experience high levels of mental health symptoms following deployment to Iraq and Afghanistan, yet many do not seek treatment. We interviewed 30 National Guard soldiers with prior deployments to Iraq or Afghanistan to assess mental health treatment barriers and the role of peers in treatment engagement. Interview transcripts were analyzed by a multidisciplinary research team using techniques drawn from grounded theory. The following themes were identified: (1) personal acceptance of having a mental health problem rather than treatment access is the major barrier to treatment entry; (2) tightly connected, supportive peer networks can decrease stigma related to mental health problems and encourage treatment; however, soldiers in impoverished or conflicted peer networks are less likely to receive these benefits; and (3) soldiers are generally positive about the idea of peer-based programs to improve treatment engagement, although they note the importance of leadership support, peer assignment, and unit specialty in implementing these programs. We conclude that some, but not all, naturally occurring peer networks serve to overcome stigma and encourage mental health treatment seeking by soldiers. Formal peer-based programs may assist soldiers not sufficiently benefitting from natural peer networks, although there are barriers to implementation.

In total, 66 healthy, sexually active professional Polish soldiers, aged between 27 and 44, who didn't report any symptoms of urogenital infection were investigated. Urine samples taken from these patients were investigated using molecular methods (Cobas TaqMan, real-time PCR) in March-April 2012 in the Military Institute of Medicine, Warsaw, Poland. In the investigated group of 66 Polish soldiers, two 33-34 year old men were asymptomatic carriers of Chlamydia trachomatis (3.0%). They confirmed having casual sexual activity without prevention with many women. In the examined group of Polish soldiers the relatively low level of chlamydial infections found may result from the use of preventive measures during sexual activity. According to the examined men, the common use of condoms is mainly connected with the fear of HIV infection. Screening tests for Chlamydia trachomatis in the Polish Armed Forces are not performed, therefore incidence rates of chlamydial infections remain unknown. The authors plan further investigations with a larger group of professional soldiers.

    Treating combat deployed soldiers is becoming more prevalent and needed in psychiatry. Modern combat produces unique psychological challenges, including those without criteria for post-traumatic stress disorder (PTSD). This article will attempt to share the primary author's experience with psychotherapy in a combat zone, along with understanding the general themes of dreams the author encountered while being deployed. Toward that end, the primary author [RW] discusses his personal experiences in Iraq working with soldiers whom he saw and treated while in theatre, with a particular focus on the dreams they reported. The co-authors [EG and MI] afterward collaborated with the primary author to formulate and provide insight into the dreams from a Jungian perspective.

    Exposure therapy is an evidence-based treatment for posttraumatic stress disorder (PTSD), but research evaluating its effectiveness with active duty service members is limited. This report examines the effectiveness of virtual reality exposure therapy (VRE) for active duty soldiers (N = 24) seeking treatment following a deployment to Iraq or Afghanistan. Relative to their pretreatment self-reported symptoms on the PTSD Checklist, Military Version (M = 60.92; SD = 11.03), patients reported a significant reduction at posttreatment (M = 47.08; SD = 12.70; p < .001). Sixty-two percent of patients (n = 15) reported a reliable change of 11 points or more. This study supports the effectiveness of exposure therapy for active duty soldiers and extends previous research on VRE to this population. PMID:21294166

    Viral hepatitis rates among U.S. Army soldiers in Europe have been found to be two to three times higher than corresponding rates for soldiers stationed in the U.S. Sera from 89 per cent of a representative Army unit with 865 members and a known hepatitis problem were tested for HBsAg, anti-HBs, anti-HBc, and anti-HA. The prevalence of HB markers was 20 per cent, and hepatitis A antibody was present in 25 per cent. A six-month follow-up, conducted on 260 individuals initially negative for all four tests, revealed that 11 of these were now HB seropositive, whereas none had seroconverted to anti-HA positive. The HB virus was the principal agent responsible for hepatitis in the unit surveyed. PMID:228562

    Paleoparasitological investigations revealed the presence of intestinal helminths in samples taken from the abdominal cavities of two German soldiers, recovered in the First World War site named "Kilianstollen" in Carspach, France. Eggs from roundworm, whipworm, tapeworm and capillariids were identified. The morphological and morphometrical comparison, followed by statistical analyses, showed that the Carspach capillariid eggs are similar to rodent parasites. Poor sanitary conditions in the trenches, the lack of knowledge of parasites, and the widespread presence of commensal animals, can explain the occurrence of such parasites in human intestines. This study is the second dealing with 20th century human samples. It confirms the presence of intestinal worms in First World War German soldiers. In this case study, the application of statistics to precise measurements facilitated the diagnosis of ancient helminth eggs and completed the microscopic approach.

    Historical information on stream stage/discharge relations from eight U.S. Geological Survey (USGS) streamflow-gaging stations was used to analyze channel-bed elevation change along Soldier Creek, a stream affected by multiple disturbances in northeast Kansas. The analysis provided information on the spatial (location, type, magnitude) and temporal (timing, duration, trend, rate) dimensions of channel change. Channel changes determined for Soldier Creek included extensive changes resulting from channelization and changes of relatively limited extent following a flood. The results were used to document channel changes, partly reconstruct historical channel conditions, infer the causes of channel change, and estimate the occurrence of future channel changes.

    The present review addresses the importance of leader behaviors in influencing the extent to which various stressors soldiers experience (e.g., high workload and lack of sleep) are related to different types of strains (e.g., psychological health, poor job satisfaction, and low morale). Research conducted by the Walter Reed Army Institute of Research (WRAIR) in the area of leadership is reviewed. Researchers at the WRAIR have examined the role of leadership as a predictor of stress, as a buffer against the negative effects of stress, and as a variable that predicts or enables variables that have been found to decrease the adverse effects of stress (e.g., role clarity, self-efficacy, and job engagement). A key strength of the WRAIR program of research is the use of multilevel modeling to examine how perceptions of leadership at the unit level are related to unit and individual soldier well-being and motivation.

    Division of labor among workers is common in insect societies and is thought to be important in their ecological success. In most species, division of labor is based on age (temporal castes), but workers in some ants and termites show morphological specialization for particular tasks (physical castes). Large-headed soldier ants and termites are well-known examples of this specialization. However, until now there has been no equivalent example of physical worker subcastes in social bees or wasps. Here we provide evidence for a physical soldier subcaste in a bee. In the neotropical stingless bee Tetragonisca angustula, nest defense is performed by two groups of guards, one hovering near the nest entrance and the other standing on the wax entrance tube. We show that both types of guards are 30% heavier than foragers and of different shape; foragers have relatively larger heads, whereas guards have larger legs. Low variation within each subcaste results in negligible size overlap between guards and foragers, further indicating that they are distinct physical castes. In addition, workers that remove garbage from the nest are of intermediate size, suggesting that they might represent another unrecognized caste. Guards or soldiers are reared in low but sufficient numbers (1-2% of emerging workers), considering that <1% usually perform this task. When challenged by the obligate robber bee Lestrimelitta limao, an important natural enemy, larger workers were able to fight for longer before being defeated by the much larger robber. This discovery opens up opportunities for the comparative study of physical castes in social insects, including the question of why soldiers appear to be so much rarer in bees than in ants or termites.

    Background: The consideration of specific trauma-associated emotions poses a challenge for the differential treatment planning in trauma therapy. Soldiers experiencing deployment-related posttraumatic stress disorder often struggle with emotions of guilt and shame as a central component of their PTSD. Objective: The purpose of this study was to examine the extent to which soldiers’ PTSD symptoms and their trauma-related guilt and shame may be affected as a function of their ability to develop compassionate imagery between their CURRENT SELF (today) and their TRAUMATIZED SELF (back then). Method: The sample comprised 24 male German soldiers diagnosed with PTSD who were examined on the Posttraumatic Diagnostic Scale (PDS) and two additional measures: the Emotional Distress Inventory (EIBE) and the Quality of Interaction between the CURRENT SELF and the TRAUMATIZED SELF (QUI-HD: Qualität der Interaktion zwischen HEUTIGEN ICH und DAMALIGEN ICH) at pre- and post-treatment and again at follow-up. The treatment used was imagery rescripting and reprocessing therapy (IRRT). Results: Eighteen of the 24 soldiers showed significant improvement in their PTSD symptoms at post-treatment and at follow-up (on their reliable change index). A significant change in trauma-associated guilt and shame emerged when compassionate imagery was developed towards one’s TRAUMATIZED SELF. The degree and intensity of the guilt and shame felt at the beginning of treatment and the degree of compassionate imagery developed toward the TRAUMATIZED SELF were predictors for change on the PDS scores. Conclusions: For soldiers suffering from specific war-related trauma involving PTSD, the use of self-nurturing, compassionate imagery that fosters reconciling with the traumatized part of the self can effectively diminish trauma-related symptoms, especially when guilt and shame are central emotions.

    Objective: This study evaluated the influence of a multiple injury control intervention on injury and physical fitness outcomes among soldiers attending United States Army Ordnance School Advanced Individual Training. Methods: The study design was quasiexperimental involving a historical control group (n = 2559) that was compared to a multiple intervention group (n = 1283). Interventions in the multiple intervention group included modified physical training, injury education, and a unit based injury surveillance system (UBISS). The management responsible for training independently formed an Injury Control Advisory Committee that examined surveillance reports from the UBISS and recommended changes to training. On arrival at school, individual soldiers completed a demographics and lifestyle questionnaire and took an army physical fitness test (APFT: push-ups, sit-ups, and two mile run). Injuries among soldiers were tracked by a clinic based injury surveillance system that was separate from the UBISS. Soldiers completed a final APFT eight weeks after arrival at school. Results: Cox regression (survival analysis) was used to examine differences in time to the first injury while controlling for group differences in demographics, lifestyle characteristics, and physical fitness. The adjusted relative risk of a time loss injury was 1.5 (95% confidence interval 1.2 to 1.8) times higher in the historical control men and 1.8 (95% confidence interval 1.1 to 2.8) times higher in the historical control women compared with the multiple intervention men and women, respectively. After correcting for the lower initial fitness of the multiple intervention group, there were no significant differences between the multiple intervention and historical control groups in terms of improvements in push-ups, sit-ups, or two mile run performance. Conclusions: This multiple intervention program contributed to a reduction in injuries while improvements in physical fitness were similar to a

    Aberrant neuronal activity in injured peripheral nerves is believed to be an important factor in the development of neuropathic pain (NPP). Channel protein pCREB of that activity has been shown to mitigate the onset of associated molecular events in the nervous system, and sodium hydrosulfide (NaHS) could inhibit the expression of pCREB. However, whether NaHS could relieve the pain, it needs further experimental research. Furthermore, the clinical potential that NaHS was used to relieve pain was limited so it would be required. To address these issues, the rats of sciatic nerve chronic constriction injury (CCI) were given intraperitoneal injection of NaHS containing hydrogen sulfide (H2S). The experimental results showed that NaHS inhibited the reduction of paw withdrawal thermal latency (PWTL), mechanical withdrawal threshold (MWT), and the level of pCREB in CCI rats in a dose-dependent manner and they were greatly decreased in NaHSM group (P < 0.05). NaHS alleviates chronic neuropathic pain by inhibiting expression of pCREB in the spinal cord of Sprague-Dawley rats. PMID:25506383

    Spinal cord injured (SCI) patients have sexual disorders including erectile dysfunction (ED), impotence, priapism, ejaculatory dysfunction and infertility. Treatments for erectile dysfunction include four steps. Step 1 involves smoking cessation, weight loss, and increasing physical activity. Step 2 is phosphodiesterase type 5 inhibitors (PDE5I) such as Sildenafil (Viagra), intracavernous injections of Papaverine or prostaglandins, and vacuum constriction devices. Step 3 is a penile prosthesis, and Step 4 is sacral neuromodulation (SNM). Priapism can be resolved spontaneously if there is no ischemia found on blood gas measurement or by Phenylephrine. For anejaculatory dysfunction, massage, vibrator, electrical stimulation and direct surgical biopsy can be used to obtain sperm which can then be used for intra-uterine or in-vitro fertilization. Infertility treatment in male SCI patients involves a combination of the above treatments for erectile and anejaculatory dysfunctions. The basic approach to and management of sexual dysfunction in female SCI patients are similar as for men but do not require treatment for erectile or ejaculatory problems. PMID:22837080

    Treadmill training has been shown to accelerate locomotor recovery and to improve weight bearing during treadmill walking in spinal cats. In human patients treadmill training is increasingly used in rehabilitation after incomplete spinal cord injury. In this study we examined training effects in spinal cord injured rats with an incomplete dorsal lesion. Recovery was examined with an open field locomotor score, kinematic analysis on the treadmill, and several functional tests (i.e. foot print evaluation, narrow beam crossing, grid walking, open field exploratory activity). During the course of 5 weeks after the injury, a substantial amount of recovery occurred in the treadmill trained as well as in the untrained rats. If compared to the control lesioned rats, which showed a high level of spontaneous hindlimb movements at 7-14 days post lesion, no additional beneficial effect of a 5-week daily treadmill training on the locomotor outcome could be detected in the trained group. The only change observed was a slightly larger exploratory activity of the trained rats. It is probable that the spared ventral and ventro-lateral fibers allowed spontaneous recovery and 'self-training' to occur to such an extend that systematic treadmill training did not provide additional improvement.

The French experience will be illustrated by 6 initiatives answering to 6 challenges to do with TBI specificities:1. bridging the gap, between initial rehabilitation and community re-entry, via transitional units dealing with assessment, retraining, social/vocational orientation and follow-up. Today, there are 30 such units based on multidisciplinary teams.2. assessing recovery by TBI-specific and validated evaluation tools: EBIS holistic document, BNI Screening of higher cerebral functions, Glasgow outcome extended, and QOLIBRI, a TBI-specific quality of life tool.3. promoting specific re-entry programmes founded on limited medication, ecological neuro-psychological rehabilitation, exchange groups and workshops, violence prevention, continuity of care, environmental structuration, and "resocialisation".4. taking into account the "head injured family"5. facilitating recovery after sports-related concussion6. facing medico-legal consequences and compensation: In that perspective, we developed guidelines for TBI-specific expert appraisal, including mandatory neuro-psychological assessment, family interview and an annual forum gathering lawyers and health professionals.

    Blastocystis hominis is a common intestinal parasite found in humans living in poor sanitary conditions, living in tropical and subtropical climates, exposed to infected animals, or consuming contaminated food or water. The aim of this study was to determine the prevalence of B. hominis in Polish military personnel returning from peacekeeping missions in Iraq and Afghanistan. In total, 1,826 stool samples were examined. Gastrointestinal parasites were detected in 17% of the soldiers. The examined stool samples most frequently contained vacuolar forms of B. hominis (15.3%) and cysts of Entamoeba coli (1.0%) or Giardia lamblia (0.7%). In 97.1% of stool samples from infected soldiers, we observed less than five developmental forms of B. hominis in the field of view (40×). The parasite infections in soldiers were diagnosed in the autumn and the spring. There was no statistical correlation between age and B. hominis infection. Our results show that peacekeeping missions in countries with tropical or subtropical climates could be associated with risk for parasitic diseases, including blastocystosis.

    Military personnel report significant and increasing mental health problems in the months following return from combat. Nevertheless, studies have not assessed the impact of mental health training with this at-risk population. The present study evaluated the efficacy of a prototype mental health training module designed for U.S. soldiers 3-6 months after returning from combat; the module was a component of the Battlemind Training system. Soldiers (N = 1,645) were randomly assigned by platoon to 1 hour of training or a survey-only control group. Baseline surveys were conducted immediately before training; a training satisfaction survey was administered immediately after training, and a follow-up survey was administered 6 months later. Immediate postsession surveys were conducted with 681 subjects, and follow-up surveys were conducted with 542 soldiers. The Battlemind Training module received positive ratings from participants, and those who received it reported significantly better adjustment in terms of posttraumatic stress disorder symptoms, depression, and life satisfaction at follow-up compared to those in the survey-only control group. Changes in attitudes about the stigma of seeking mental health care were found immediately posttraining, but not at follow-up. The findings demonstrate that brief mental health training can be effective in reducing mental health systems with at-risk occupational groups.

    This study aimed to merge existing methodologies of identifying high-risk soldiers to create a comprehensive testable model to assist leaders in the identification, mitigation, and prevention of negative behavioral health (BH) issues. In 2011, a total of 2,664 active duty U.S. Army soldiers completed a survey of demographic and military characteristics, combat exposures, and BH diagnoses and symptoms. Multivariable linear and logistic regression models were fit to examine the relationship between demographic and military characteristics, subthreshold behavioral and social health issues, and positive screening for BH symptoms. The "recent loss of someone close" and self-reporting a history of BH issues were the strongest and most consistent predictors of subthreshold behavioral and social health issues. This study found that individual and occupational factors were associated with subthreshold behavioral and social health issues, which were in turn, associated with screening positive for BH symptoms. The recent loss of someone close (an indicator of grief and loss) was not the study's primary research question, but warrants further investigation to determine its impact on the mental well-being of soldiers.

    This study aimed to evaluate the potential contribution of informal community initiatives and formal interventions in support of former child soldiers' resilience in the wake of armed conflict. Using a cross-sectional survey design, a stratified random sample of 330 formerly recruited and 677 nonrecruited young people was consulted about their perspective on desirable support for former child soldiers provided by close support figures, communities, humanitarian organizations, and governments. Data analysis occurred by conducting qualitative thematic analysis and statistical chi-square analysis to explore clusters, similarities, and variations in reported support across the different "agents," hereby comparing the perspectives of formerly recruited and non-recruited participants. The results indicated that formerly recruited and non-recruited participants had comparable perspectives that call for the contribution of various informal and formal support systems to former child soldiers' human capacities and the communal sociocultural fabric of war-affected societies. This highlights the importance of community-based, collective, and comprehensive support of formerly recruited young people and their surroundings in the aftermath of armed conflict.

    The Altitude Performance Test is a measure designed to assess an individual's degree of acclimatization to reduce the risk of acute mountain sickness during high-altitude activities. The aim of this study was to investigate the hypothesis that test results will improve in pre-acclimatized soldiers after several days of further acclimatization. The Altitude Performance Test consists of an uphill run at high altitude. The event is timed and performed with continuous oxygen saturation (SpO2) monitoring. The individual's time and lowest SpO2 measurement are recorded. This test was performed on the first day of arriving at 11,060 ft, and after 9 days at the same location. The 37 male soldiers were all pre-acclimatized before arrival. The sleeping altitude remained constant at 11,060 ft, and the daytime altitudes increased up to a maximum of 15,775 ft. Test results improved significantly after a further 9 days of acclimatization (time, -11 s; SpO2, +5%-points; p ≤ 0.001). This is remarkable because all soldiers were pre-acclimatized and showed only minor acute mountain sickness symptoms during the entire stay. This indicates that the acclimatization process is not finished after amelioration of altitude symptoms. The demonstrated improvement in physical performance could prove very important, particularly during military missions performed at high altitude.

    This study examined recent-onset (i.e., acute) and persistent (i.e., chronic) life stressors among 54 acutely suicidal US Army Soldiers and examined their relationship to persistence of suicidal crises over time. Soldiers with a history of multiple suicide attempts reported the most severe suicide ideation (F(2,51) = 4.18, p = 0.021) and the greatest number of chronic stressors (F(2,51) = 5.11, p = 0.009). Chronic but not acute stressors were correlated with severity of suicide ideation (r = 0.24, p = 0.026). Participants reporting low-to-average levels of chronic stress resolved suicide ideation during the 6-month follow-up, but participants reporting high levels of chronic stress did not (Wald χ(1) = 4.57, p = 0.032). Soldiers who are multiple attempters report a greater number of chronic stressors. Chronic, but not acute-onset, stressors are associated with more severe and longer-lasting suicidal crises.

Our results show that peacekeeping missions in countries with tropical or subtropical climates could be associated with risk for parasitic diseases, including blastocystosis. PMID:25732683

    Poor postural stability has been identified as a risk factor for lower extremity musculoskeletal injury. The additional weight of body armor carried by Soldiers alters static postural stability and may predispose Soldiers to lower extremity musculoskeletal injuries. However, static postural stability tasks poorly replicate the dynamic military environment, which places considerable stress on the postural control system during tactical training and combat. Therefore, the purpose of this study was to examine the effects of body armor on dynamic postural stability during single-leg jump landings. Thirty-six 101st Airborne Division (Air Assault) Soldiers performed single-leg jump landings in the anterior direction with and without wearing body armor. The dynamic postural stability index and the individual stability indices (medial-lateral stability index, anterior-posterior stability index, and vertical stability index) were calculated for each condition. Paired sample t-tests were performed to determine differences between conditions. Significant differences existed for the medial-lateral stability index, anterior-posterior stability index, vertical stability index, and dynamic postural stability index (p < 0.05). The addition of body armor resulted in diminished dynamic postural stability, which may result in increased lower extremity injuries. Training programs should address the altered dynamic postural stability while wearing body armor in attempts to promote adaptations that will result in safer performance during dynamic tasks.

    Numerous media reports (press, radio, television) and several scientific publications on psychiatric disorders among Polish soldiers participating in peace missions in Iraq indicate that there is a serious threat caused by the disorders defined in the DSM-IV classification as: acute stress disorder (ASD) and post-traumatic stress disorder (PTSD). The authors analyzed psychiatric documentation and conducted their own researches, which revealed that adjustment disorders, especially with anxiety, are the main psychiatric problem among Polish soldiers in Iraq, while incidence of ASD and PTSD is very low. The aim of this publication is to present and compare mental disorders which occur during peace missions and welfare actions according to the international ICD-10 and American DSM-IV classifications. The authors paid attention to the role and significance of hitherto diagnosed impulsive disorders, which occur among the soldiers in Iraq as the intermittent explosive disorder, according to DSM-IV. The general and essential conclusions of the presented publication is that the guidelines of diagnosing mental disorders that occur during peace missions and welfare actions should be developed and introduced quickly.

    Self-injury is often motivated by the desire to reduce the intensity of negative affect. This suggests that people who self-injure may have difficulty suppressing negative emotions. We sought to determine whether self-injuring individuals exhibit impaired inhibitory control over behavioral expressions of negative emotions, when responding to images containing aversive emotional content. Self-injuring participants and healthy controls completed a Stop Signal Task in which they were asked to judge the valence (positive or negative) of images. Three types of images depicted emotional content (neutral/positive/negative). A fourth type depicted self-cutting. An unpredictable "stop signal" occurred on some trials, indicating that participants should inhibit their responses to images presented on those trials. Compared to controls, self-injuring participants showed poorer inhibition to images depicting negative emotional content. Additionally, they showed enhanced inhibition to self-injury images. In fact, self-injuring participants showed comparable response inhibition to cutting images and positive images, whereas controls showed worse inhibition to cutting images compared to all other types of images. Consistent with the emotion regulation hypothesis of self-injury, people who self-injure showed impaired negative emotional response inhibition. Self-injuring individuals also demonstrated superior control over responses to stimuli related to self-injury, which may have important clinical implications.

    Although former child soldiers face considerable challenges after their return from the warring faction to the war-affected society, the presence of resources enables many to maintain well-being in the wake of child soldiering. Academic research has recently engaged with identifying these salient resources, but has left the question why they are helpful to former child soldiers largely unaddressed. This study therefore focuses on the meaning underlying certain phenomena that causes them to become resources. Semistructured in-depth interviews and a free-listing task on resources were conducted with 48 northern Ugandan former child soldiers. The phenomenological hermeneutical method is applied to analyze their lived experiences and the meaning they assign to resources. Four essential themes emerge from this study, representing the fourfold meaning of resources for former child soldiers in helping them (a) to break with their former existence as child soldiers, (b) to be able to overcome the challenges in their current life, (c) to belong to others and the environment to which they have returned, and (d) to become the person they aspire to be. Considering these research themes in the context of former child soldiers' return process, parallels with theories on transition are recognized and further explored so as to contextualize this emerging meaning. As such, this research delivers empirical evidence illustrating how resources help to pilot former child soldiers through transition in the wake of child soldiering.

    Dermal disease is significant cause of morbidity among soldiers in a combat setting. For example, among American combat troops in Vietnam, disability from skin disease was one of the single most important medical causes of man-days lost from combat. Currently, the US Army makes shower or bath facilities available to soldiers in the field on a weekly basis. US Army after-action reports and anecdotal descriptions from the field indicate that this may not be an optimal regimen for the maintenance of personal hygiene, especially with respect to diseases of the skin. Determination of the optimal frequency of showering of bathing for soldiers in a combat setting is complicated by the fact of showering or bathing for soldiers in a combat setting is complicated by the fact that soldiers in the US Army may be involved in field exercise or combat in many different areas of the world with a variety of climatic conditions. Although certain aspects of the role of environmental factors in the incidence and severity of dermal disease have been documented, the role of hygiene in the potential mitigation of these effects has not been evaluated. The present project entails a comprehensive review and analysis of available literature in order to determine the health impact of shower/bath frequency for soldiers in a combat setting. An integral component of this work is an evaluation of the impact of climate, and microclimate produced by clothing, on the type, frequency, and severity of skin disease. There is relatively large body of information concerning the effectiveness of antimicrobial soaps in minimizing the incidence and severity of dermal disease. This data will be evaluated to determine whether use of these soaps, or an increase in the use of cleansing agents in general, will result in a decrease in the severity and incidence of diseases of the skin for soldiers in the field. 32 refs., 2 figs., 1 tab.

    Objectives: To explore the immediate pre-crash activities and the routine traffic exposure (street crossing and play) in a sample of urban children struck by automobiles. In particular, the traffic exposure of children who were struck while playing was compared with that of those struck while crossing streets. Design: Cross sectional survey. Setting: Urban pediatric emergency department. Patients: A total of 139 children ages 4–15 years evaluated for acute injuries resulting from pedestrian-motor vehicle collisions during a 14 month period. Main outcome measures: Sites of outdoor play, daily time in outdoor play, weekly number of street crossings, pre-crash circumstance (play v walking). Results: Altogether 39% of the children routinely used the street and 64% routinely used the sidewalks as play areas. The median number of street crossings per week per child was 27. There were no differences in exposures for the 29% who were hit while playing compared with the 71% who were hit while walking. Although 84% of the children walked to or from school at least one day per week, only 15% of the children were struck while on the school walking trip. The remainder were injured either while playing outdoors or while walking to other places. Conclusions: Urban children who are victims of pedestrian crashes have a high level of traffic exposure from a variety of circumstances related to their routine outdoor playing and street crossing activities. The distributions of traffic exposures were similar across the sample, indicating that the sample as a whole had high traffic exposure, regardless of the children's activity preceding the crash. Future pedestrian injury programs should address the pervasive nature of children's exposure to traffic during their routine outdoor activities. PMID:12226122

    Objective To determine and compare outcomes with accepted benchmarks in burn care at six academic burn centers. Background Since the 1960s, U.S. morbidity and mortality rates have declined tremendously for burn patients, likely related to improvements in surgical and critical care treatment. We describe the baseline patient characteristics and well-defined outcomes for major burn injuries. Methods We followed 300 adults and 241 children from 2003–2009 through hospitalization using standard operating procedures developed at study onset. We created an extensive database on patient and injury characteristics, anatomic and physiological derangement, clinical treatment, and outcomes. These data were compared with existing benchmarks in burn care. Results Study patients were critically injured as demonstrated by mean %TBSA (41.2±18.3 for adults and 57.8±18.2 for children) and presence of inhalation injury in 38% of the adults and 54.8% of the children. Mortality in adults was 14.1% for those less than 55 years old and 38.5% for those age ≥55 years. Mortality in patients less than 17 years old was 7.9%. Overall, the multiple organ failure rate was 27%. When controlling for age and %TBSA, presence of inhalation injury was not significant. Conclusions This study provides the current benchmark for major burn patients. Mortality rates, notwithstanding significant % TBSA and presence of inhalation injury, have significantly declined compared to previous benchmarks. Modern day surgical and medically intensive management has markedly improved to the point where we can expect patients less than 55 years old with severe burn injuries and inhalation injury to survive these devastating conditions.

    Spinal cord injury results in immediate disruption of neuronal membranes, followed by extensive secondary neurodegenerative processes. A key approach for repairing injured spinal cord is to seal the damaged membranes at an early stage. Here, we show that axonal membranes injured by compression can be effectively repaired using self-assembled monomethoxy poly(ethylene glycol)-poly(D,L-lactic acid) di-block copolymer micelles. Injured spinal tissue incubated with micelles (60 nm diameter) showed rapid restoration of compound action potential and reduced calcium influx into axons for micelle concentrations much lower than the concentrations of polyethylene glycol, a known sealing agent for early-stage spinal cord injury. Intravenously injected micelles effectively recovered locomotor function and reduced the volume and inflammatory response of the lesion in injured rats, without any adverse effects. Our results show that copolymer micelles can interrupt the spread of primary spinal cord injury damage with minimal toxicity.

    Selective agar is inadequate for supporting recovery of injured cells. During risk assessment of certain foods, both injured and noninjured cells must be enumerated. In this study, a new method (agar spray method) for recovering sublethally heat-injured microorganisms was developed and used for recovery of heat-injured Salmonella Typhimurium and Listeria monocytogenes. Molten selective agar was applied as an overlay to presolidified nonselective tryptic soy agar (TSA) by spray application. Heat-injured cells (55°C for 10 min in 0.1% peptone water or 55°C for 15 min in sterilized skim milk) were inoculated directly onto solidified TSA. After a 2-h incubation period for cell repair, selective agar was applied to the TSA surface with a sprayer, and the plates were incubated. The recovery rate for heat-injured Salmonella Typhimurium and L. monocytogenes with the spray method was compared with the corresponding rates associated with TSA alone, selective media alone, and the conventional overlay method (selective agar poured on top of resuscitated cells grown on TSA and incubated for 2 h). No significant differences (P > 0.05) were found in pathogen recovery obtained with TSA, the overlay method, and the spray method. However, a lower recovery rate (P < 0.05) was obtained for isolation of injured cells on selective media. Overall, these results indicate that the agar spray method is an acceptable alternative to the conventional overlay method and is a simpler and more convenient approach to recovery and detection of injured cells.

    This technical note describes a method for distinguishing normal skin tissue samples from those electrically injured by Fourier transform infrared microspectroscopy (FTIR MSP). Furthermore, the infrared spectral features of electrically injured cells and tissues were evaluated to identify molecular changes in epidermal cells. In the present study, 20 human hand tissue samples were evaluated macroscopically and histopathologically. The electrically injured skin samples were subdivided into 2 regions [normal cell regions (NCRs) and polarized cell regions (PCRs)] and 14 major spectral absorption bands were selected. The spectral results showed that the band absorbance at 1080, 1126, 1172, 1242, 1307, 1403, 1456, 1541, 2852, 2925, 2957, 3075, and 3300cm(-1) increased significantly both in the stratum and non-stratum corneum of the PCRs in electrically injured skin tissues samples. No significant difference was found between normal skin and the NCR of the electrically injured skin samples. The band absorbance ratios of A1172/A1126, A1456/A1403, and A2925/A2957 were significantly increased, whereas the A1652/A1541 ratio was decreased in the PCR of the stratum corneum and non-stratum corneum. Baseline changes from 4000 to near 1737cm(-1) were observed in the spectra of the electrically injured skin samples, which were interpreted in terms of the pathological process involved in electrical injury. FTIR-MSP presents a useful method to provide objective spectral markers for the assisted diagnosis of electrical marks.

    This study aimed to analyze the frequency, nature, and consequences of footballers playing matches while injured, and to examine the impact on injury surveillance findings. High levels of inter-rater reliability and content validity were established for a tool designed to document players who were already injured at the start of a match. The tool was implemented in three English football teams (a Championship, League 1, and League 2 team) for one season, using a "time loss" definition of injury. One hundred forty-three matches were surveyed, revealing 102 match appearances by players who were already injured. Almost half of all games featured at least one injured player, with episodes of playing with injury occurring more frequently and lasting longer in League 2 players compared with higher level players. No association was observed between the number of injured players starting matches and match outcome [χ(2) (4, N = 143) = 3.27, P = 0.514]. Fifteen percent of all injury episodes captured were only through prospective documentation of playing while injured. The findings show that both traumatic and overuse injuries are managed by footballers through competitive matches, and have important implications for aiding understanding of the epidemiology of injury in professional football.

  16. Knockdown of the juvenile hormone receptor gene inhibits soldier-specific morphogenesis in the damp-wood termite Zootermopsis nevadensis (Isoptera: Archotermopsidae).

    The Methoprene-tolerant (Met) protein has been established as a juvenile hormone (JH) receptor. Knockdown of the Met gene caused precocious metamorphosis and suppression of ovarian development. However, the function of Met in caste development of social insects is unclear. In termites, JH acts as a central factor for caste development, especially for soldier differentiation, which involves two molts from workers via a presoldier stage. Increased JH titer in workers is needed for the presoldier molt, and the high JH titer is maintained throughout the presoldier period. Although presoldiers have the fundamental morphological features of soldiers, the nature of the cuticle is completely different from that of soldiers. We expected that JH signals via Met are involved in soldier-specific morphogenesis of the head and mandibles during soldier differentiation, especially in the presoldier period, in natural conditions. To test this hypothesis, we focused on soldier differentiation in an incipient colony of the damp-wood termite Zootermopsis nevadensis. Met homolog (ZnMet) expression in heads increased just after the presoldier molt. This high expression was reduced by ZnMet double stranded (dsRNA) injection before the presoldier molt. Although this treatment did not cause any morphological changes in presoldiers, it caused strong effects on soldiers, their mandibles being significantly shorter and head capsules smaller than those of control soldiers. Injection of ZnMet dsRNA throughout the presoldier stage did not affect the formation of soldier morphology, including cuticle formation. These results suggested that the rapid increase in ZnMet expression and subsequent activation of JH signaling just after the presoldier molt are needed for the formation of soldier-specific weapons. Therefore, besides its established role in insect metamorphosis, the JH receptor signaling also underlies soldier development in termites.

    Health status of soldiers affects their quality of life and combat readiness. The aim of the research was to explore the differences in health-related quality of life (HRQoL) between combat ready und unready soldiers and to what extent are clinically assessed combat readiness and psychological dimensions related to self-reported HRQoL. The study included 402 consecutively selected soldiers aged 21 to 54 (mean age 35.3 +/- 6.0) who were classified on the basis of a regular health examination as combat ready (N=327) and unready (N=75). HRQoL was assessed using the Short Form-8 Questionnaire and psychological dimensions using the Brief Symptom Inventory. There were no significant differences in physical and mental components of HRQoL between combat ready and unready soldiers. Clinically assessed combat readiness and psychological symptomatic dimensions were weak predictors of HRQoL. Higher intensity of psychoticism and less years in military service were the only significant predictor of higher physical component of HRQoL (p=0.027 and p=0.020, respectively) but accounted for low variability (each 1%). None variable was a predictor of mental component. In conclusion, clinically assessed combat readiness of soldiers and psychological symptomatic dimensions are poor predictors of HRQoL. HRQoL should be introduced in evaluation of combat readiness.

    The objective of this study was to determine the knowledge, attitudes and practices of young male soldiers about family planning. This was a cross-sectional study conducted at the Gendarmerie Command Headquarters, Elazig City, eastern Turkey, carried out on 14 April 2004. One hundred ninety-one of 209 soldiers who were present at the Gendarmerie Command Headquarters were included in the study. A questionnaire, developed by the researchers evaluating the goals of the study, was filled out by the subjects prior to the Family Planning Seminar given to the soldiers. Data were assessed using SPSS and the chi-square test was used for statistical analysis. Defining family planning correctly, being familiar with planning methods and a knowledge of sexually transmitted diseases (STD) and their prevention was found to be at low levels among soldiers. A knowledge of family planning, birth control methods, identification and prevention of STD was higher with higher levels of education. The most familiar family planning methods were condom and oral contraceptive use. Soldiers constitute one of the most significant target groups for education programs.

    Complex societies where individuals exhibit division of labor with physical polymorphism, behavioral specialization, and caste formation have evolved several times throughout the animal kingdom. Recently, such complex sociality has been recognized in digenean trematodes; evidence is limited to 6 marine species. Hence, the extent to which a soldier caste is present throughout the Trematoda is sparsely documented, and there are no studies detailing the structure of a species lacking such a social structure. Here we examine colony structure for an additional 5 echinostomoid species, 4 of which infect the marine snail Cerithidea californica and 1 (Echinostoma liei) that infects the freshwater snail Biomphalaria glabrata . For all species, we present redia morphology (pharynx and body size) and the distribution of individuals of different castes throughout the snail body. When morphological evidence indicated the presence of a soldier caste, we assessed behavior by measuring attack rates of the different morphs toward heterospecific trematodes. Our findings indicate that each of the 4 species from C. californica have a permanent soldier caste while E. liei does not. The observed intra- and inter-specific variation of caste structure for those species with soldiers, and the documentation of colony structure for a species explicitly lacking permanent soldiers, emphasizes the diverse nature of trematode sociality and the promise of the group to permit comparative investigations of the evolution and ecology of sociality.

    Anger and aggression are among the most common issues reported by returning service members from combat deployments. However, the pathways between combat exposure and anger and aggression have not been comprehensively characterized. The present study aimed to characterize the relationship between trait anger, combat exposure, post-deployment PTSD, and aggression. U.S. Army soldiers (N = 2,420) were administered anonymous surveys assessing combat exposure, current PTSD symptoms and aggression, as well as trait anger items 3 months after returning from deployment to Afghanistan. PTSD symptom levels were related to aggression at higher levels of trait anger, but not evident among soldiers who had lower levels of trait anger. The pathway from combat exposure to PTSD, and then to aggression, was conditional upon levels of trait anger, such that the pathway was most evident at high levels of trait anger. This was the first study to our knowledge that concurrently modeled unconditional and conditional direct and indirect associations between combat exposure, PTSD, trait anger, and aggression. The findings can be helpful clinically and for developing screening protocols for combat exposed Soldiers. The results of this study suggest the importance of assessing and managing anger and aggression in soldiers returning from combat deployment. Anger is one of the most common complaints of returning soldiers and can have debilitating effects across all domains of functioning. It is imperative that future research efforts are directed toward understanding this phenomenon and developing and validating effective treatments for it.

    We identified the soldier-specific compounds in the Japanese subterranean termite, Reticulitermes speratus, to clarify their ethological roles. Silica gel column chromatography separated one major soldier-specific compound in the hexane fraction accounting for 70-80% of the total amount of the fraction, while cuticular hydrocarbons constituted the rest. We identified the compound as β-selinene by gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) spectroscopy. Comparative GC analyses of the major exocrine glands detected the compound in the soldier's frontal gland. Both soldiers and workers made aggregation to the hexane fraction, as well as to the crushed heads and head extract of the soldiers. They did not aggregate to cuticular hydrocarbons, making it likely that β-selinene was the aggregation pheromone in this species. The opportunistic predator of this termite, Lasius japonicus, was also attracted to the compounds. The ant workers, therefore, would use the termite aggregation pheromone as a kairomone for hunting them. PMID:21897019

    Testicular cancer is the most common malignancy in young men. To evaluate knowledge and awareness of that cancer, and of the practice of testicular self-examination (TSE), we developed a questionnaire which was distributed to 717 male soldiers and 200 of their military physicians. 21% of the soldiers had received some explanation of the importance of TSE, but only 16% were actually instructed how to perform TSE, and only 2% practiced it regularly. 24% had never examined their testicles before, 185 only rarely, and 6% often. With increased age, TSE frequency increased, but previous education, type of military unit, and ethnic origin had no affect. 99% of military physicians had been taught how to examine breasts, but only 70% had been taught routine testicular examination. 22% performed it, but 27% never did. 84% had never taught their soldiers the importance of TSE, although 51% taught female soldiers breast self-examination. There was a significant lack of awareness of the importance of regular practice of TSE among both soldiers and their army physicians.

    Longitudinal data were examined to predict soldiers' morale, satisfaction with Army life, and the effects of family issues on performance of duties during an overseas deployment (Sinai peacekeeping force during the spring of 1995). Few variables were significant predictors of the outcome measures; however, rank, leaders' support for families, prior satisfaction with Army life and with information released about the deployment appeared to predict better outcomes during the deployment. Rank and leaders' support for families appeared to be more important for married soldiers while satisfaction with predeployment information seemed to be more important for single soldiers. Those who were worried about the effects of the deployment on their families also tended to report interference with their duty performance because of family concerns, but that effect was offset by perceived leaders' concern for families. In conclusion, it appears to the authors that the pre-existing factors studied had much less to do with deployment outcomes than did leadership success before and during the deployment. That's good news for Army leaders about their power to have a positive effect on soldiers' morale during overseas deployments but may be bad news for anyone hoping to find a "magic bullet" for pre-identification of soldiers most likely to retain high morale, regardless of their leadership's competence during an overseas deployment.

    Six direct plating media were evaluated for their suitability to recover uninjured, heat-injured, and freeze-injured cells of four strains of Listeria monocytogenes from four foods. Cells were inoculated into foods to achieve ca. 10(2) to 10(3), 10(4) to 10(5), or 10(5) to 10(6) viable cells per ml or g (low, medium, and high populations, respectively). No appreciable differences in recovery of the four test strains within a treatment were observed. Generally, recovery on all test media was similar and not markedly affected by freeze treatment. Modified Despierres agar and modified McBride Listeria agar yielded poorer recovery of heat-injured cells than did McBride Listeria agar and gum base-nalidixic acid-tryptone soya agar. Overall, gum base-nalidixic acid-tryptone soya agar was best for recovering L. monocytogenes from pasteurized milk and chocolate ice cream mix. Enumeration was complicated by the growth of background microflora present in Brie cheese and cabbage, especially at the low inoculum. Dominguez Rodriguez isolation agar was superior for recovering L. monocytogenes from Brie cheese, whereas modified Despierres agar was best for recovering the organism from cabbage. Direct plating procedures can successfully be utilized for recovering healthy and injured L. monocytogenes from foods containing low populations of background microflora.

    Nearly 2 million Traumatic Brain Injuries (TBI) occur in the U.S. each year, with societal costs approaching $60 billion. Including mild TBI and concussion, TBI's are prevalent in soldiers returning from Iraq and Afghanistan as well as in domestic athletes. Long-term risks of single and cumulative head impact dosage may present in the form of post traumatic stress disorder (PTSD), depression, suicide, Chronic Traumatic Encephalopathy (CTE), dementia, Alzheimer's and Parkinson's diseases. Quantifying head impact dosage and understanding associated risk factors for the development of long-term sequelae is critical toward developing guidelines for TBI exposure and post-exposure management. The current knowledge gap between head impact exposure and clinical outcomes limits the understanding of underlying TBI mechanisms, including effective treatment protocols and prevention methods for soldiers and athletes. In order to begin addressing this knowledge gap, Cleveland Clinic is developing the "Intelligent Mouthguard" head impact dosimeter. Current testing indicates the Intelligent Mouthguard can quantify linear acceleration with 3% error and angular acceleration with 17% error during impacts ranging from 10g to 174g and 850rad/s2 to 10000rad/s2, respectively. Correlation was high (R2 > 0.99, R2 = 0.98, respectively). Near-term development will be geared towards quantifying head impact dosages in vitro, longitudinally in athletes and to test new sensors for possible improved accuracy and reduced bias. Long-term, the IMG may be useful to soldiers to be paired with neurocognitive clinical data quantifying resultant TBI functional deficits.

    AIDS is a major problem for military personnel because they are young and sexually active. The UN has over 70,000 troops deployed in 18 different assignments; since 1980, more of these soldiers died of AIDS than have been killed in combat. National military forces in developing countries are decimated by the epidemic. In some armies, especially those in Africa, HIV rates are over 45%, and for officers in some flying and armored units, 100% positivity has been reported. AIDS strikes mainly at the 20-40 age group, often taking senior officers and high-ranking managers. The prevalence of infection may compromise the safety of the blood supply in military hospitals. Military leaders are also worried about exposing their troops to HIV infection from allies; such exposure could jeopardize their combat readiness. Recently demobilized personnel could contribute to AIDS awareness programs as instructors and role models. One major challenge in prevention programs is to convince troops to practice safe sex. Sexually transmitted disease infection rates in the military are between two and five times higher than the rates in the general population. The key issue is whether to screen new recruits. Screening improves blood safety; however, the issues of privacy, confidentiality, and human rights must be considered. In some nations, HIV-infected persons are automatically excluded from the ranks. The question also arises whether special AIDS clinics should be established for soldiers and their families. The issue of screening senior officers for HIV before promotion to higher ranks is also intricate. Stigmatization of those rejected may lead to fewer candidates seeking military careers. The HIV-positive soldier should not be deprived of active duty, training, deployment, and promotion unless debilitating symptoms emerge. The prevention and care programs must resolve: greater training and sharing of data between civil and military sectors, greater international cooperation, long

    This study evaluated whether using a web-linked accelerometer, plus mandatory physical training, is associated with various weight- and fitness-related outcomes in overweight/obese active duty soldiers. Soldiers who failed the height/weight standards of the Army Physical Fitness Test (APFT) were randomized to use a Polar FA20 accelerometer device (polar accelerometer group [PA], n = 15) or usual care (UC, n = 13) for 6 months. Both groups received 1.5 hours of lifestyle instruction. We collected data at baseline, 2, 4, and 6 months, and evaluated group differences in temporal changes in study outcomes. At 6 months, 1/28 subjects (UC) passed the APFT height/weight standards. There were no group differences in changes in weight (PA: -0.1 kg vs. UC: +0.3 kg; p = 0.9), body fat (PA: -0.9% vs. UC: -1.1%; p = 0.9), systolic blood pressure (PA: +1.3 mm Hg vs. UC: -2.1 mm Hg; p = 0.2), diastolic blood pressure (PA: +3.8 mm Hg vs. UC: -2.4 mm Hg; p = 0.3), or resting heart rate in beats per minute (bpm) (PA: +7.8 bpm vs. UC: +0.1 bpm; p = 0.2). These results suggest that using an accelerometer with web-based feedback capabilities plus mandatory physical training does not assist in significant weight loss or ability to pass the APFT height/weight standards among overweight/obese soldiers.

    Based on a sample of 54 Israeli soldiers (51 % non-religious, 49 % religious) surveyed upon their return from combat, this study investigates the moderating role of religiosity as a factor that may strengthen cognitive processing tied to the belief in oneself to persevere (i.e., self-efficacy) after trauma and/or as a factor tied to enhanced external social support that religious individuals in particular may benefit from by their involvement in a religious community. Findings revealed (1) social support was tied to greater resilience within the general sample; (2) religious soldiers were less susceptible to traumatic stress than non-religious soldiers; and (3) religiosity moderated the relationship between self-efficacy and traumatic stress but not the relationship between social support and traumatic stress. Implications of findings are discussed.

    This retrospective evaluation explores anonymous survey data to identify predictors of Soldier willingness to report and seek treatment for behavioral health problems during screening mandated by the Department of Defense (DoD). After controlling for stigma and barriers to care concerns, Soldiers with high (+1SD) combat exposure and high (+1SD) levels of posttraumatic stress symptoms were significantly more willing to report these symptoms during DoD-mandated screening. Furthermore, Soldiers who perceived that their unit leaders took action on anonymous Unit Behavioral Health Needs Assessment survey findings were significantly more likely to report a willingness to disclose behavioral health problems and seek treatment for the same. Performance improvement considerations are discussed. PMID:25651151

    The purpose of this study was to extend the demand-control model (R. A. Karasek, 1979) by examining coping as an additional factor. It was hypothesized that perceived job control only buffered the demand-strain relationship when individuals used active coping and exacerbated the relationship when individuals used passive coping. Soldiers (N=638) were surveyed before and during a 6-month peacekeeping deployment to Kosovo. Results partially confirmed the hypotheses. Even after controlling for general psychological health at predeployment, job control moderated the relationship between demands and psychological health during deployment when soldiers used active coping. No significant 3-way interactions were found for religious coping and passive coping. Implications for demand-control modeling and potential applications of the findings to soldier and leader training are discussed. PMID:16248692

    The Israeli National Health Insurance Law allocates a national healthcare budget to the sickness funds, which provide medical care to civilian population. Medical care for members of the IDF is financed through the budget of the Ministry of Defense and is not included in the national healthcare budget. Benefits provided to soldiers serving in the permanent forces are far more extensive than those provided to civilians. Because of no co-payments, poor management, and the cost-based budget, military healthcare costs in Israel are expected to exceed civilian healthcare costs, adjusting for age and sex. The present paper derives age- and sex-based capitation rates for military personnel, and compares military and civilian age-based expenditure and capitation rates. The study population comprised career soldiers and civilians aged 21-54 years. Expenses of career soldiers were calculated to provide information on the financial costs of medical services for each age group in 2003. Overall expenses for women were higher than for men in all age groups. As anticipated, the older the group, the higher the total expenditure for both men and women. In-patient care represented a higher percentage of the total costs for men (28.3%) than for women (22.1%). Emergency room care was higher for women in the 22-24 age group but comparable to that of men in higher age groups. Specialist visits represented a significantly higher percentage of the total costs for women than for men in the 22-24 and 25-34 age groups (by 6% and 15%, respectively). The difference decreased to 13% in the 35-44 age groups and, in the 45-54 age group, the difference for men was 14% higher than for women.

    While numerous studies on former child soldiers (FCS) have shown mental health needs, adequate services are a challenge. This study aimed to identify priorities, barriers and facilitators of mental health care for Sierra Leonean FCS. Thematic analysis was done on 24 qualitative interviews with participants from diverse sectors. Priorities of mental distress, substance abuse, and gender-based violence were common among FCS clients. Barriers were governmental support and communication with other providers. Perceived facilitators of care were primary- and secondary-level interventions. A public mental health model would feasibly build upon local, culturally embraced interventions, targeting local priorities and reducing barriers to care.

    The lipid fraction of larvae of the black soldier fly Hermetia illucens was shown to contain lauric acid (38.43 wt %) and its esters, azelaic and sebacic acids, and azelaic acid dibutyl ester. The dominant compound in the group of identified glycerides was lauric acid monoglyceride (0.70 wt %). Glycerides were also represented by triglycerides and diglycerides of lauric acid. Sterols were represented primarily by phytosterols (over 75%), the major of which was alpha-sitosterol (45%). The identified lipid complex composition is apparently determined by the biological characteristics of the fly Hermetia illucens and ensures antibacterial defence of larvae and stability of lipids at changing ambient temperature.

    In stays in tropical countries, the French military, and travelers in general, are exposed to diseases transmitted by the fecal-oral route, some of which are vaccine-preventable. Here we report a 42-yer-old soldier with hepatitis A, which first appeared on his return from a military operation in the Central African Republic. Despite its excellent immunogenicity and a duration of seroprotection extending beyond 20 years in the vast majority of cases, the hepatitis A vaccine can fail. This reminds us of the importance of combining vaccine and non-vaccine prevention in tropical countries, especially in precarious living conditions.

    Out of the ruins of World War I arose the poignant verse of the "Trench Poets." Lieutenant Colonel John McCrae, Canadian doctor, professor, and soldier, exemplified this verse in his haunting poem "In Flanders Fields." After establishing himself as a respected physician and university lecturer in Canada and the United States, he served in World War I as a physician and artillery commander. In 1918, after a grueling tour of duty, McCrae witnessed one of the Great War's most horrific technological creations: chemical warfare. He suffered from asthma and probable chronic obstructive pulmonary disease all his life, dying at age 45 of cerebral meningitis.

    Road crashes result in substantial trauma and costs to societies around the world. Robust costing methods are an important tool to estimate costs associated with road trauma, and are key inputs into policy development and cost-benefit analysis for road safety programmes and infrastructure projects. With an expanding focus on seriously injured road crash casualties, in addition to the long standing focus on fatalities, methods for costing seriously injured casualties are becoming increasingly important. Some road safety agencies are defining a seriously injured casualty as an individual that was admitted to hospital following a road crash, and as a result, hospital separation data provide substantial potential for estimating the costs associated with seriously injured road crash casualties. The aim of this study is to establish techniques for estimating the human recovery costs of (non-fatal) seriously injured road crash casualties directly from hospital separation data. An individuals' road crash-related hospitalisation record and their personal injury insurance claim were linked for road crashes that occurred in New South Wales, Australia. These records provided the means for estimating all of the costs to the casualty directly related to their recovery from their injuries. A total of 10,897 seriously injured road crash casualties were identified and four methods for estimating their recovery costs were examined, using either unit record or aggregated hospital separation data. The methods are shown to provide robust techniques for estimating the human recovery costs of seriously injured road crash casualties, that may prove useful for identifying, implementing and evaluating safety programmes intended to reduce the incidence of road crash-related serious injuries.

    Transplantation studies in mice and rats have shown that human embryonic stem cell-derived cardiomyocytes (hESC-CMs) can improve the function of infarcted hearts1–3, but two critical issues related to their electrophysiological behavior in vivo remain unresolved. First, the risk of arrhythmias following hESC-CM transplantation in injured hearts has not been determined. Second, the electromechanical integration of hESC-CMs in injured hearts has not been demonstrated, so it is unclear if these cells improve contractile function directly through addition of new force-generating units. Here we use a guinea pig model to show hESC-CM grafts in injured hearts protect against arrhythmias and can contract synchronously with host muscle. Injured hearts with hESC-CM grafts show improved mechanical function and a significantly reduced incidence of both spontaneous and induced ventricular tachycardia (VT). To assess the activity of hESC-CM grafts in vivo, we transplanted hESC-CMs expressing the genetically-encoded calcium sensor, GCaMP34, 5. By correlating the GCaMP3 fluorescent signal with the host ECG, we found that grafts in uninjured hearts have consistent 1:1 host-graft coupling. Grafts in injured hearts are more heterogeneous and typically include both coupled and uncoupled regions. Thus, human myocardial grafts meet physiological criteria for true heart regeneration, providing support for the continued development of hESC-based cardiac therapies for both mechanical and electrical repair.

    Detection of Listeria in food products is often limited by performance of enrichment media used to support growth of Listeria to detectable levels. In this study, growth curves were generated using healthy and heat-injured Listeria monocytogenes strain F5069 in three nonselective and five selective enrichment broths. Nonselective enrichment media included the current Food and Drug Administration Bacteriological Analytical Manual Listeria enrichment broth base (BAM), Listeria repair broth (LRB), and Trypticase soy broth. Selective enrichment media included BAM with selective agents and LRB with selective agents, BCM L. monocytogenes preenrichment broth, Fraser broth, and UVM-modified Listeria enrichment broth. The Gompertz equation was used to model the growth of L. monocytogenes. Gompertz parameters were used to calculate exponential growth rate, lag-phase duration (LPD), generation time, maximum population density (MPD), and time required for repair of injured cells. Statistical differences (P < 0.05) in broth performance were noted for LPD and MPD when healthy and injured cells were inoculated into the broths. With the exception of Fraser broth, there were no significant differences in the time required for the repair of injured cells. Results indicate that the distinction between selective and nonselective broths in their ability to grow healthy Listeria and to repair sublethally injured cells is not solely an elementary issue of presence or absence of selective agents.

    The glial scar formed at the site of traumatic spinal cord injury (SCI) has been classically hypothesized to be a potent physical and biochemical barrier to nerve regeneration. One longstanding hypothesis is that the scar acts as a physical barrier due to its increased stiffness in comparison to uninjured spinal cord tissue. However, the information regarding the mechanical properties of the glial scar in the current literature is mostly anecdotal and not well quantified. We monitored the mechanical relaxation behavior of injured rat spinal cord tissue at the site of mid-thoracic spinal hemisection 2 weeks and 8 weeks post-injury using a microindentation test method. Elastic moduli were calculated and a modified standard linear model (mSLM) was fit to the data to estimate the relaxation time constant and viscosity. The SLM was modified to account for a spectrum of relaxation times, a phenomenon common to biological tissues, by incorporating a stretched exponential term. Injured tissue exhibited significantly lower stiffness and elastic modulus in comparison to uninjured control tissue, and the results from the model parameters indicated that the relaxation time constant and viscosity of injured tissue were significantly higher than controls. This study presents direct micromechanical measurements of injured spinal cord tissue post-injury. The results of this study show that the injured spinal tissue displays complex viscoelastic behavior, likely indicating changes in tissue permeability and diffusivity.

    1999-12-01

    A method of recovering sublethally heat-injured bacteria was developed. The procedure (termed the agar underlay method) uses a nonselective agar underlaid with a selective medium. In a two-chambered petri dish, the Lutri plate (LP), a nonselective agar is inoculated with a population of sublethally heat-injured bacteria. After a 2-h repair incubation period, selective agar is added to the bottom chamber of the LP and incubated. By diffusing through the nonselective top agar, selective agents from the underlay medium impart selectivity to the system. By the agar underlay method, recovery rates of the heat-injured food-borne pathogens Escherichia coli O157:H7 and Salmonella typhimurium were not different (P > 0. 05) from recovery rates determined with nonselective media. Sublethally heat-injured cells (60 degrees C for 1.5 min in buffer or 80 degrees C for 30 s on meat surfaces) grew and produced a typical colony morphology and color reaction when the agar underlay procedure was used with the appropriate respective selective agars. Unlike agar overlay methods for injury repair, the agar underlay procedure allows the typical selective-medium colony morphology to develop and allows colonies to be more easily picked for further characterization. Higher recovery rates of heat-injured fecal enterococci from bovine fecal samples and total coliforms from animal waste lagoons were obtained by the agar underlay method with selective agars than by direct plating on the respective selective media.

    One hundred and eighteen clinical records of soldiers attending the Psychological Unit of the Ospedale Militare "A. Riberi" in Turin were included in the study. Records assessed according to the "Somatization Index" and the scores obtained were analysed using statistical methods (t test) according to the following parameters: geographical origin of the family (North/South); place of residence (southern Italians resident in the South/southern Italians resident in the North, and rural/urban environment); educational level (5th class in primary school/upper secondary school). A substantial overlapping was observed between the groups studied. Various hypotheses can be put forward: 1) the index is not capable of distinguishing between expressiveness in psychic terms and expressiveness in somatic terms in relation to the patient's psychosocial malaise; 2) the results of the index are valid and may be interpreted in the following ways: a) the Italian population is homogeneous with regard to the modes of expressing and communicating psychosocial malaise; b) the results obtained are influenced by the excessive homogeneity of the sample studied in terms of age; c) the results obtained are biased by the strong reactive nature of the soldier's psychological problems with respect to Military Service: the reaction has characteristics of immediacy and should therefore be interpreted as a maladjustment which is experienced and expressed in a psychic context; d) the results are influenced by the name of the place of study ("psychological unit") and by the "civil" appearance of its workers.

    Recent research and advances in robotics have led to the development of novel platforms leveraging new sensing capabilities for semantic navigation. As these systems becoming increasingly more robust, they support highly complex commands beyond direct teleoperation and waypoint finding facilitating a transition away from robots as tools to robots as teammates. Supporting future Soldier-Robot teaming requires communication capabilities on par with human-human teams for successful integration of robots. Therefore, as robots increase in functionality, it is equally important that the interface between the Soldier and robot advances as well. Multimodal communication (MMC) enables human-robot teaming through redundancy and levels of communications more robust than single mode interaction. Commercial-off-the-shelf (COTS) technologies released in recent years for smart-phones and gaming provide tools for the creation of portable interfaces incorporating MMC through the use of speech, gestures, and visual displays. However, for multimodal interfaces to be successfully used in the military domain, they must be able to classify speech, gestures, and process natural language in real-time with high accuracy. For the present study, a prototype multimodal interface supporting real-time interactions with an autonomous robot was developed. This device integrated COTS Automated Speech Recognition (ASR), a custom gesture recognition glove, and natural language understanding on a tablet. This paper presents performance results (e.g. response times, accuracy) of the integrated device when commanding an autonomous robot to perform reconnaissance and surveillance activities in an unknown outdoor environment.

    2009-06-01

    Theory and research deriving from social identity or self-categorization perspectives often starts out with the presumption that social actors necessarily view societal objects such as nations or states as human categories. However, recent work suggests that this may be only one of a number of forms that societal representation may take. For example, nations may be understood variously as peoples, places, or institutions. This paper presents findings from a qualitative interview study conducted in England, in which soldiers and civilians talked about nationhood in relation to military service. Analysis indicated that, in this context, speakers were often inclined to use the terms 'Britain', 'nation', and 'country' as references to a political institution as opposed to a category of people. In addition, there were systematic differences between the ways in which the two samples construed their nation in institutional terms. The civilians were inclined to treat military service as a matter of obedience to the dictates of the Government of the day. In contrast, the soldiers were more inclined to frame military service as a matter of loyalty to state as symbolically instantiated in the body of the sovereign. Implications for work adopting a social identity perspective are discussed.

    We developed and evaluated a military-focused HIV prevention intervention to enhance HIV risk-reduction knowledge, motivation, and behaviors among Angolan soldiers. Twelve bases were randomly assigned to HIV prevention or control conditions, yielding 568 participants. HIV prevention participants received training in preventing HIV (4.5 days) and malaria (0.5 days). Control participants received the reverse. Monthly booster sessions were available after each intervention. We assessed participants at baseline, three and six months after the training. HIV prevention participants reported greater condom use and less unprotected anal sex at three months, as well as greater HIV-related knowledge and perceived vulnerability at three and six months. Within-group analyses showed HIV prevention participants increased condom use, reduced unprotected vaginal sex, and reduced numbers of partners at both follow-ups, while control participants improved on some outcomes at three months only. A military-focused HIV prevention intervention may increase HIV-related knowledge, motivation, and risk reduction among African soldiers. PMID:18324469

    Suicide is difficult to predict and prevent and remains a leading cause of death worldwide. Although soldiers historically have had a suicide rate well below that of the general population, the suicide rate among members of the U.S. Army has increased markedly over the past several years and now exceeds that of the general population. This paper reviews psychosocial factors known to be associated with the increased risk of suicidal behavior in general and describes how some of these factors may be especially important in understanding suicide among soldiers. Moving forward, the prevention of suicide requires additional research aimed at: (a) better describing when, where, and among whom suicidal behavior occurs, (b) using exploratory studies to discover new risk and protective factors, (c) developing new methods of predicting suicidal behavior that synthesize information about modifiable risk and protective factors from multiple domains, and (d) understanding the mechanisms and pathways through which suicidal behavior develops. Although the scope and severity of this problem is daunting, the increasing attention and dedication to this issue by the Armed Forces, scientists, and society provide hope for our ability to better predict and prevent these tragic outcomes in the future.

    Child soldiers often experience complex trauma as victims and perpetrators, and feelings of guilt may affect their psychological health. The relationship between the children's traumatic experiences as victims or perpetrators, their perception of themselves as victim or perpetrator, guilt and psychopathology were investigated: of the 330 former child soldiers interviewed, 50.8 % perceived themselves as victims and 19.1 % as perpetrators. On psychopathology measures, scores within the clinical range were 33 % for posttraumatic stress disorder (PTSD), 36.4 % for major depressive disorder (MDD), and 26.1 % for externalizing problems. Low socio-economic status, traumatic experience as perpetrator, and guilt were significant predictors of PTSD. Significant predictors of MDD were low socio-economic status, traumatic experiences as victim, and guilt. A greater number of traumatic experiences as perpetrator and guilt were associated with externalizing problems. The current paper underscores the significance of guilt following traumatic experiences and has implications for the development of clinical interventions for war-affected children.

    Despite international bans, more than 250,000 children and adolescents are exploited as soldiers worldwide, almost half of them in Africa. These children are exposed to a tremendous amount of violence and are often forced to commit atrocities themselves. In the present study, 330 former Ugandan child soldiers (age: 11-17, female: 48.5%) were interviewed regarding traumatic experiences, trauma-related guild, and posttraumatic stress disorder (PTSD). Affective and cognitive aspects of guilt were assessed with the Trauma-related Guilt Inventory (TRGI) and PTSD with a diagnostic interview (MINI-KID). Children had been abducted at a mean age of 10.75 years and served for an average period of 19.81 months. They were exposed to numerous traumatic experiences during abduction, e. g., 86.4% were exposed to killings, 87.9% were threatened with death, 52.6% were forced to kill another person, and 25.8% were raped. Diagnostic criteria for PTSD were fulfilled by 33% of the children. Higher guilt cognitions were significantly related to posttraumatic stress disorder. The current study has implications for the development of clinical interventions for war-affected children.

    Whether a service member is active duty or part of the National Guard, deployment of these service members is a major issue for most families. There is limited knowledge of the experience of multiple deployments on the family. The purpose of this study was to describe experiences of wives of National Guard soldiers that were deployed more than once. Nine wives were interviewed. An analysis of the interviews revealed four themes: (1) "Life Goes On" (i.e., despite the repeated deployments, life continues at home); (2) the "Guard is a Different Animal" (i.e., life as a National Guard spouse is different from that of an active duty spouse); (3) "It's a Mind-Set" (i.e., how wives cope their husband's deployment); and (4) "Going Back Again" (i.e., wives' experiences of multiple deployments). Exploring how multiple deployments affects wives of National Guard soldiers is helpful in understanding their experiences and the adjustments that must be made in family life. Knowledge of the experiences of these wives may help in formulating more effective interventions with families who have experienced multiple deployments.

    Highly mobile multipurpose wheeled vehicle (HMMWV or Humvee) crashes present an important issue for the U.S. military. The aim of this study was to provide a descriptive analysis of occupants of military motor vehicle (MMV) crashes involving HMMWVs that occurred among deployed U.S. Army Soldiers. Crash-related data were collected from the U.S. Army Combat Readiness/Safety Center on MMV crashes among active duty Army personnel between 1999 and 2006. Records for 964 occupants with injuries from HMMWV crashes were analyzed, which represented 52% of the total occupants of MMV crashes. A significant association was observed between injury and engagement in combat, odds ratio 1.49 (1.03, 2.16). The risk of injury was greatest for gunners, odds ratio 2.37 (1.43, 3.92), and injury cost related to the crash was significantly related to prior deployment status (p < 0.001) and role of Soldier in the vehicle (Operator p = 0.005, Gunner p = 0.003). There was also a decrease over time in the number of crashes resulting in injury (p < 0.001). These data support the development of interventions that address the specific risks detailed, including the use of combat simulation training, increased protection for vulnerable positions, and enforcement of safety regulations.

    This report describes the conduct and results of the Psychological Response Study, the purpose of which was to further the understanding of the likely responses of troops involved in a tactical nuclear war (TNW). The goals of the study were to estimate the most likely types of psychological responses to a TNW and the relationship between various psychological responses and performance in combat in terms of battlefield fatigue casualties (BFC). Subjects of this study were three hundred fifty-nine US Army troops who received one of six treatments (battlefield scenarios) in which three types of combat were crossed with two distances to the battle. Data were collected immediately from the subjects after they were read a description of one of the six battlefield scenarios and asked to visualize themselves in the described battlefield. Also collected were data from 11 experts in the field of TNW, again using a questionnaire. Results from the troops indicate that there was an interaction between Type of Combat and Soldier Type (infantry vs. armor). Infantrymen in the TNW scenario were significantly more extreme in their expectations about the behavior and performance of themselves and their compatriots. Also, unit and soldier-related variables such as cohesion and commitment were found to be significantly related to performance.

    Members of a Swedish United Nations (UN) battalion of 362 soldiers were bled just before and immediately after their 6 month tour of duty in Cyprus during 1985. Sera were tested for presence of specific antibodies to sand fly fever (SF) Sicilian, SF Naples, and Toscana viruses by both indirect immunofluorescence antibody test (IFT) and plaque reduction neutralization test (PRNT). Of 298 serum pairs available, seroconversion was noted in 11 soldiers: 7 cases for SF Sicilian, 3 for SF Naples, and 1 for Toscana virus. IFT and PRNT revealed identical results. Seroconversion was associated with clinical disease in 7 out of 7, 2 out of 3, and 0 out of 1 for SF Sicilian, SF Naples, and Toscana infections, respectively. Virus isolation was attempted on acute-phase sera collected from febrile patients. Of 5 such acute-phase sera from patients with serologically verified SF, virus was recovered from 2: 1 strain of SF Sicilian virus and 1 strain of SF Naples virus.

    The aim of this study was to compare selected physiological variables and performance markers of soldiers from two "elite" units of the British Army. Ten soldiers from each of the two units were recruited for this study (n = 20). All participants completed three tests while carrying a 20 kg backpack load: (1) a maximal treadmill test using the Bruce protocol; (2) a 2 mile backpack run test specific to Unit A on a consistently flat tarmac road; and (3) a 29 km time-trial over hilly terrain typical of a mountainous area used by Unit B for performance assessment. Heart rate, maximal blood lactate concentration and performance (run time) were assessed during all three tests, with peak oxygen uptake also being measured during the maximal treadmill test. Measurements of anthropometry, isokinetic strength and mental toughness (MT48) were also recorded. There were no significant differences in terms of performance markers between the units (P > 0.05). Performance on the maximal treadmill test correlated with performance on the 2 mile backpack run test (r = -0.57) and 29 km time-trial (r = -0.66). Performance on the 2 mile backpack run test in turn correlated with 29 km time-trial performance (r = -0.77), accounting for 59% of the variance. In conclusion, the maximal treadmill test and the 2 mile backpack run test are useful indicators of performance on the arduous hill march and could be employed in the screening and selection of potential recruits.

    Larvae of the black soldier fly, Hermetia illucens (Diptera: Stratiomyidae), are voracious feeders of organic material and may thus be used in simple engineered systems to reduce organic waste in low- and middle-income countries. Controlled feeding experiments with standard fodder were conducted to assess the optimum amount of organic waste to be added to a CORS system (Conversion of Organic Refuse by Saprophages). A daily feeding rate of 100 mg chicken feed (60% moisture content) per larva resulted in an optimum trade-off between material reduction efficiency (41.8%, SE 0.61) and biomass production (prepupal dry weight: 48.0 mg, SE 2.0). Applied to market waste and human faeces, this corresponds to a potential daily feeding capacity of 3-5 kg/m(2) and 6.5 kg/m(2), respectively. In addition, H. illucens prepupae quality was assessed to determine their suitability to substitute fishmeal in animal feed production. The chitin-corrected crude protein content ranged from 28.2 to 42.5%, depending on the amount of food provided to the larvae. Based on our study, a waste processing unit could yield a daily prepupal biomass of 145 g (dry mass) per m(2). We conclude that larvae of the black soldier fly are potentially capable of converting large amounts of organic waste into protein-rich biomass to substitute fishmeal, thereby contributing to sustainable aquaculture.

    Modern dairies cause the accumulation of considerable quantity of dairy manure which is a potential hazard to the environment. Dairy manure can also act as a principal larval resource for many insects such as the black soldier fly, Hermetia illucens. The black soldier fly larvae (BSFL) are considered as a new biotechnology to convert dairy manure into biodiesel and sugar. BSFL are a common colonizer of large variety of decomposing organic material in temperate and tropical areas. Adults do not need to be fed, except to take water, and acquired enough nutrition during larval development for reproduction. Dairy manure treated by BSFL is an economical way in animal facilities. Grease could be extracted from BSFL by petroleum ether, and then be treated with a two-step method to produce biodiesel. The digested dairy manure was hydrolyzed into sugar. In this study, approximately 1248.6g fresh dairy manure was converted into 273.4 g dry residue by 1200 BSFL in 21 days. Approximately 15.8 g of biodiesel was gained from 70.8 g dry BSFL, and 96.2g sugar was obtained from the digested dairy manure. The residual dry BSFL after grease extraction can be used as protein feedstuff. PMID:21367596

  1. Rehabilitation and restoration: orthopaedics and disabled soldiers in Germany and Britain in the First World War.

    Anderson, Julie; Perry, Heather R

    2014-01-01

    This article offers a comparative analysis of the evolution of orthopaedics and rehabilitation within German and British military medicine during the Great War. In it, we reveal how the field of orthopaedics became integral to military medicine by tracing the evolution of the discipline and its practitioners in each nation during the war. In doing so, however, we document not only when and why both medical specialists and military officials realized that maintaining their respective national fighting forces depended upon the efficient rehabilitation of wounded soldiers, but also how these rehabilitative practices and goals reflected the particularities of the military context, civilian society and social structure of each nation. Thus, while our comparison reveals a number of similarities in the orthopaedic developments within each nation as a response to the Great War, we also reveal significant national differences in war-time medical goals, rehabilitation treatments and soldierly 'medical experiences'. Moreover, as we demonstrate, a social and cultural re-conceptualization of the disabled body accompanied the medical advancements developed for him; however, this re-conceptualization was not the same in each nation. Thus, what our article reveals is that although the guns of August fell silent in 1918, the war's medical experiences lingered long thereafter shaping the future of disability medicine in both nations.

  2. Two war-torn soldiers: combat-related trauma through an intersubjective lens.

    Carr, Russell B

    2013-01-01

    The author, himself an Iraq war veteran, presents a contemporary psychodynamic understanding, known as intersubjective therapy, of combat-related Post-traumatic Stress Disorder (PTSD). At the onset of this case example, the patient was highly suicidal and his PTSD symptoms had not responded to a first-line treatment: manualized cognitive processing therapy. Robert Stolorow's intersubjective, psychodynamic approach to traumatic emotional experiences was then selected for treatment, and illustrates how combat in Afghanistan shattered this soldier's world and self experience. Therapeutic action arises from this intersubjective perspective by providing a relational home so that unendurable emotions can be borne, processed, and integrated to achieve a more constant and individualized sense of self. Being a two-person model of therapy, the author also describes how his work with this traumatized soldier affected him, ultimately contributing to his own sense of authentic existing. The author discusses the need for therapists to recognize and acknowledge to traumatized patients their shared finitude and the ubiquity of trauma. In the Postscript, the patient describes what he felt was therapeutic and contrasts this to his previous experiences with manualized cognitive processing therapy.

  3. A multimodal interface for real-time soldier-robot teaming

    Recent research and advances in robotics have led to the development of novel platforms leveraging new sensing capabilities for semantic navigation. As these systems becoming increasingly more robust, they support highly complex commands beyond direct teleoperation and waypoint finding facilitating a transition away from robots as tools to robots as teammates. Supporting future Soldier-Robot teaming requires communication capabilities on par with human-human teams for successful integration of robots. Therefore, as robots increase in functionality, it is equally important that the interface between the Soldier and robot advances as well. Multimodal communication (MMC) enables human-robot teaming through redundancy and levels of communications more robust than single mode interaction. Commercial-off-the-shelf (COTS) technologies released in recent years for smart-phones and gaming provide tools for the creation of portable interfaces incorporating MMC through the use of speech, gestures, and visual displays. However, for multimodal interfaces to be successfully used in the military domain, they must be able to classify speech, gestures, and process natural language in real-time with high accuracy. For the present study, a prototype multimodal interface supporting real-time interactions with an autonomous robot was developed. This device integrated COTS Automated Speech Recognition (ASR), a custom gesture recognition glove, and natural language understanding on a tablet. This paper presents performance results (e.g. response times, accuracy) of the integrated device when commanding an autonomous robot to perform reconnaissance and surveillance activities in an unknown outdoor environment.

  4. State institutions and social identity: National representation in soldiers' and civilians' interview talk concerning military service.

    PubMed

    2009-06-01

    Theory and research deriving from social identity or self-categorization perspectives often starts out with the presumption that social actors necessarily view societal objects such as nations or states as human categories. However, recent work suggests that this may be only one of a number of forms that societal representation may take. For example, nations may be understood variously as peoples, places, or institutions. This paper presents findings from a qualitative interview study conducted in England, in which soldiers and civilians talked about nationhood in relation to military service. Analysis indicated that, in this context, speakers were often inclined to use the terms 'Britain', 'nation', and 'country' as references to a political institution as opposed to a category of people. In addition, there were systematic differences between the ways in which the two samples construed their nation in institutional terms. The civilians were inclined to treat military service as a matter of obedience to the dictates of the Government of the day. In contrast, the soldiers were more inclined to frame military service as a matter of loyalty to state as symbolically instantiated in the body of the sovereign. Implications for work adopting a social identity perspective are discussed. PMID:18793493

    Background/objectives: Few studies of Chlamydia trachomatis incidence, especially among men, and most studies of C trachomatis in US military populations are cross sectional prevalence surveys. A population based retrospective cohort was used to determine risk factors for repeat diagnoses of genital C trachomatis infections among male and female soldiers with previous C trachomatis infections. Methods: All active duty soldiers diagnosed with C trachomatis genital infections between 1994 and 1998. Cohort members were passively followed until repeat diagnoses of C trachomatis infection, termination of army service, or the end of the study. Results: Among 11 771 soldiers with initial diagnoses of chlamydia, the crude rate of repeat diagnoses was 52.0 per 1000 person years. Women and men aged 20–24 were at greatest unadjusted risk of reinfection. After adjustment, women aged 20–24 and men aged 25–29 were at higher risk than their younger or older counterparts. Conclusions: Results of this study suggest that both male and female soldiers who are diagnosed with chlamydia infections have relatively high risks of reinfection through their 20s.

    The purpose of this study was to determine the reliability of military-relevant tests designed to assess soldier readiness. Forty-seven soldiers (46 men, 1 woman; 22 +/- 3 years; 80.4 +/- 11.7 kg) performed each of seven soldier readiness tests on four different occasions over the course of 8 weeks. The soldier readiness tests were: (1) 3.2-km load carriage (LC) time-trial, (2) running long jump (RLJ), (3) one-repetition maximum box lift (1RMBL), (4) 10-minute repetitive box lift and carry (RBLC), (5) simulated victim rescue (VR), (6) mock grenade throw (GT) for accuracy, and (7) simulated combat rushes (CR). Repeated measures analysis of variance revealed significant learning effects for 1RMBL, RBLC, and GT; these tests required two (1RMBL and RBLC) or three (GT) trials to obtain statistically stable values. The intraclass correlation coefficient was 0.78 to 0.89 for all tests. LC, 1RMBL, RBLC, CR, and RLJ all demonstrated standard error of measurement values that were 3% to 5%, whereas VR and GT were 9% and 36%, respectively. In conclusion, the 1RMBL, RBLC, and GT tests required familiarization before a stable value was obtained. The LC, 1RMBL, RBLC, CR, and RLJ tests (and, to a lesser degree, the VR test) demonstrated reasonably acceptable levels of reliability and measurement error, whereas the GT test did not.

    Black soldier flies, Hermetia illucens L., are distributed throughout the temperate and tropic regions of the world and are known an established method for sustainably managing animal wastes. Colonies used to conduct research on the black soldier fly within the past 20 yr have predominately been established from eggs or larvae received from a colony originated from Bacon County, GA. Consequently, little is known about the phenotypic plasticity (i.e., development and waste conversion) across strains from different regions. This study compared the development of three strains of the black soldier fly (Texas; Guangzhou, China; and Wuhan, China) and their ability to reduce dry matter and associated nutrients in swine, dairy, and chicken manure. The Wuhan strain appeared to be more fit. Larvae from Wuhan needed 17.7-29.9% less time to reach the prepupal stage than those from Guangzhou or Texas, respectively. Larvae from Wuhan weighed 14.4-37.0% more than those from Guanghzhou or Texas, respectively. Larvae from the Wuhan strain reduced dry matter 46.0% (swine), 40.1% (dairy), and 48.4% (chicken) more than the Guangzhou strain and 6.9, 7.2, and 7.9% more than the Texas strain. This study demonstrates that phenotypic plasticity (e.g., development and waste conversion) varies across populations of black soldier flies and should be taken into account when selecting and establishing a population as a waste management agent in a given region of the world.

    During the U.S. Civil War, nutritional night blindness was a common problem among soldiers forced to subsist of nutritionally inadequate diets, but medical officers typically attributed this complaint to malingering and did not suspect or appreciate a dietary basis. More than 8,000 cases of night blindness were recorded among Union troops, but many cases were not tabulated because of incomplete data for black soldiers and prisoners of war. From 1864 to 1865, during which comparable data were available for both whites and blacks, the average annual cumulative incidence of night blindness was 4.3 per 1,000 troops for whites, compared with 11.0 per 1,000 troops for blacks. Affected patients had dilated pupils that were poorly responsive to candle light. Approximately 30 cases of keratomalacia were also reported among severely malnourished and emaciated soldiers with chronic diarrhea, generally within 2 weeks before death. The reported clinical manifestations are characteristic of the full range of vitamin A deficiency eye disease from night blindness to corneal ulceration and perforation. Although medical officers typically accused affected soldiers of malingering, malingering cannot account for either the observed abnormalities of pupillary reflexes, or the corneal epithelial pathology and mortality recorded in severe cases.

    Black soldier flies, Hermetia illucens L., are distributed throughout the temperate and tropic regions of the world and are known an established method for sustainably managing animal wastes. Colonies used to conduct research on the black soldier fly within the past 20 yr have predominately been established from eggs or larvae received from a colony originated from Bacon County, GA. Consequently, little is known about the phenotypic plasticity (i.e., development and waste conversion) across strains from different regions. This study compared the development of three strains of the black soldier fly (Texas; Guangzhou, China; and Wuhan, China) and their ability to reduce dry matter and associated nutrients in swine, dairy, and chicken manure. The Wuhan strain appeared to be more fit. Larvae from Wuhan needed 17.7-29.9% less time to reach the prepupal stage than those from Guangzhou or Texas, respectively. Larvae from Wuhan weighed 14.4-37.0% more than those from Guanghzhou or Texas, respectively. Larvae from the Wuhan strain reduced dry matter 46.0% (swine), 40.1% (dairy), and 48.4% (chicken) more than the Guangzhou strain and 6.9, 7.2, and 7.9% more than the Texas strain. This study demonstrates that phenotypic plasticity (e.g., development and waste conversion) varies across populations of black soldier flies and should be taken into account when selecting and establishing a population as a waste management agent in a given region of the world.

    Ankle and foot injuries (AFI) are a major cause of Active-Duty Army (ADA) soldiers' time lost from training and combat operations. We used the Total Army Injury and Health Outcomes Database to compute the rates of AFI to identify high-risk ADA groups for the years 2000-2006. During this time, 16% of soldiers were clinically seen at least once for an AFI. Yearly, 60% to 70% of ADA soldiers with AFI had an ankle sprain/strain, and ankle sprain/strain had the highest 7-year rate of all AFIs (103 per 1,000). From 2000 to 2006, all AFI rates declined; however, enlisted male soldiers < or = 30 years of age without an advanced degree were at highest risk. A history of an AFI in the previous 2 years increased AFI rates by 93% to 160%. Our findings provide preliminary evidence for identifying specific ADA groups at high risk of AFI; these groups should be targeted for preventive interventions. PMID:21456354

    U.S. Army soldiers with mental disorders report a variety of barriers to initiating and continuing treatment. Improved understanding of these barriers can help direct mental health services to soldiers in need. A representative sample of 5,428 nondeployed Regular Army soldiers participating in the Army Study to Assess Risk and Resilience in Servicemembers completed a self-administered questionnaire and consented to linking self-administered questionnaire data with administrative records. We examined reported treatment barriers (perceived need, structural reasons, attitudinal reasons) among respondents with current Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, mental disorders who either did not seek treatment in the past year (n = 744) or discontinued treatment (n = 145). About 82.4% of soldiers who did not initiate treatment and 69.5% of those who discontinued treatment endorsed at least two barriers; 69.8% of never-treated soldiers reported no perceived need. Attitudinal reasons were cited more frequently than structural reasons among never-treated soldiers with perceived need (80.7% vs. 62.7%) and those who discontinued treatment (71.0% vs. 37.8%). Multivariate associations with sociodemographic, Army career, and mental health predictors varied across barrier categories. These findings suggest most soldiers with mental disorders do not believe they need treatment and those who do typically face multiple attitudinal and, to a lesser extent, structural barriers.

    This article sets medico legal light on torture of three former child soldiers by comparing torture methods, consequences of torture and medical observations. It is focused on these child soldiers as representatives of the many abuses of children as soldiers in armed groups. The three persons were child soldiers during 12 years in The Democratic Republic of Congo (DRC) as members of three different armed groups. They were exposed to armed conflict events, experienced torture, and participated in atrocities, sexual abuse and traditional rituals during their role in armed conflict. They were psychologically distressed with unhealthy physical and mental states. The principles for working with child soldiers are described. The model addresses basic items: The confluence of the dimensions of the items will determine the specifics of medico legal evidence of torture in child soldiers, taking into consideration inputs that are required at the macro, community and individual levels. A primary goal is to prevent violence from occurring in child soldiers. Thus, much more deliberate effort is made to address the underlying causes of recruitment of children in armed groups in DRC and to invest more resources in conflict resolution before there is an outbreak of violence. Peace education tends to be introduced too late and does little to alleviate the use of children in armed conflict in DRC.

  2. β-alanine supplementation improves tactical performance but not cognitive function in combat soldiers

    PubMed Central

    2014-01-01

    Background There are no known studies that have examined β-alanine supplementation in military personnel. Considering the physiological and potential neurological effects that have been reported during sustained military operations, it appears that β-alanine supplementation may have a potential benefit in maintaining physical and cognitive performance during high-intensity military activity under stressful conditions. The purpose of this study was to examine the effect of 28 days of β-alanine ingestion in military personnel while fatigued on physical and cognitive performance. Methods Twenty soldiers (20.1 ± 0.9 years) from an elite combat unit were randomly assigned to either a β-alanine (BA) or placebo (PL) group. Soldiers were involved in advanced military training, including combat skill development, navigational training, self-defense/hand-to-hand combat and conditioning. All participants performed a 4-km run, 5-countermovement jumps using a linear position transducer, 120-m sprint, a 10-shot shooting protocol with assault rifle, including overcoming a misfire, and a 2-min serial subtraction test to assess cognitive function before (Pre) and after (Post) 28 days of supplementation. Results The training routine resulted in significant increases in 4-km run time for both groups, but no between group differences were seen (p = 0.597). Peak jump power at Post was greater for BA than PL (p = 0.034), while mean jump power for BA at Post was 10.2% greater (p = 0.139) than PL. BA had a significantly greater (p = 0.012) number of shots on target at Post (8.2 ± 1.0) than PL (6.5 ± 2.1), and their target engagement speed at Post was also significantly faster (p = 0.039). No difference in serial subtraction performance was seen between the groups (p = 0.844). Conclusion Results of this study indicate that 4-weeks of β-alanine ingestion in young, healthy soldiers did not impact cognitive performance, but did enhance power

    The impact of basic military training (BMT) on recruit physical performance is well described. However, initial employment training (IET), the period immediately after BMT, is the final preparatory step before posting to an operational unit. There is limited evidence on the influence of this training in developing the physical attributes necessary for military duty. Therefore, this investigation determined the relative contribution of BMT and IET to develop physical capability in soldiers. Fifty-one soldiers (45 men and 6 women) were assessed at 4 time points: commencement of training (week 1), midway (week 8), at the conclusion (week 12) of BMT, and upon completion of the IET (week 18/27). Weeks 1, 12, and 18/27 are reported herein. At each time point, tasks relevant to military duties, such as 1 repetition maximum (1RM) box lift, 2 × 22 kg-jerry carry, 3.2 km of 22-kg load carriage, and preexisting assessments of military fitness, such as 20-m shuttle run, 2-minute push-ups, and sit-ups, were assessed. A subsample of recruits (n = 14) was assessed for 1RM bench press, vertical jump, 30-second high-intensity cycle ergometry, and peak treadmill oxygen consumption. A significant (p ≤ 0.05) decrease in 3.2 km of 22-kg load carriage (week 12, 1,109 ± 37 seconds; week 18/27, 1,161 ± 51 seconds), 2 × 22 kg-jerry carry (week 12, 753 ± 72 m; week 18/27, 683 ± 78 m), and 1RM bench press (week 12, 83.3 ± 16.0 kg; week 18/27, 73.2 ± 16.6 kg) was observed during IET. No change (p > 0.05) between week 12 and week 18/27 was detected in 1RM box lift, vertical jump, 30-second high-intensity cycle ergometry, sit-ups, and 20-minute shuttle run. In contrast, 2-minute push-up (week 12, 46.7 ± 2.7; week 18/27, 57.5 ± 3.1) performance increased significantly (p ≤ 0.05).

J Strength Cond Res 30(10): 2774-2780, 2016-Despite suspension of conscription in Polish Army, trainings of soldiers are still carried out. It is expected that they will be effective and will contribute to obtaining optimum level of psychophysical efficiency that enables fulfillment of military tasks. Total of 60 soldiers took part in the study. During the 9-month military service, soldiers had 200 hours of physical training and basic military training (shooting, drill, anti-chemical training, topography, general tactics, and military equipment operation). The training lasted 8 hours everyday. To assess fitness level, 4 trials were done: long jump, pull-ups, sit-ups, and 1,000 m run. Evaluation of food was based on the analysis of full board menus using the "Tables of composition and nutritional value of food products." Energy value was assessed, and content of basic nutrients was calculated. Assessment of nutritional status was based on anthropometric measurements, such as body height, body mass, and thickness of 4 selected skinfolds. Body height and body mass were the basis for the body mass index calculation. Soldiers serving in the mechanized infantry unit, after completing the training, got better results only in 1,000 m run (from 250.3 to 233.61 seconds). During the research, an average energy value of a daily food ration planned for consumption was 4,504 kcal. This value consisted of 13.2% of energy from protein, 31.9% of energy from fat, and 54.9% from carbohydrates. In the course of military service, percentage of subjects indicating overweight increased from 10.2 to 25.4%.

  6. Conscious Presence and Self Control as a measure of situational awareness in soldiers – A validation study

    PubMed Central

    2013-01-01

    Background The concept of `mindfulness´ was operationalized primarily for patients with chronic stressors, while it is rarely used in reference to soldiers. We intended to validate a modified instrument on the basis of the Freiburg Mindfulness Inventory (FMI) to measure soldiers’ situational awareness (“mindfulness”) in stressful situations/missions. The instrument we will explore in this paper is termed the Conscious Presence and Self Control (CPSC) scale. Methods The CPSC and further instruments, i.e., Perceived Stress Scale (PSS), stressful military experiences (PCL-M), life satisfaction (BMLSS), Positive Life Construction (ePLC), and self-perceived health affections (VAS), were administered to 281 German soldiers. The soldiers were mainly exposed to explosive ordnance, military police, medical service, and patients with posttraumatic stress disorders. Results The 10-item CPSC scale exhibited a one-factorial structure and showed a good internal consistence (Cronbach´s alpha = .86); there were neither ceiling nor bottom effects. The CPSC scores correlated moderately with Positive Life Construction and life satisfaction, and negatively with perceived stress and health affections. Regression analyses indicated that posttraumatic stress disorder symptoms (negative), and the development of effective strategies to deal with disturbing pictures and experiences (positive) were the best predictor of soldiers´ CPSC scores. Soldiers with health affections exhibiting impact upon their daily life had significantly lower CPSC scores than those without impairment (F=8.1; p < .0001). Conclusions As core conceptualizations of `mindfulness´ are not necessarily discussed in a military context, the FMI was adopted for military personnel populations, while its two factorial structure with the sub-constructs `acceptance´ and `presence´ was retained. The resulting 10-item CPSC scale had good internal consistence, sound associations with measures of health affections and

It has been established that the growing number of soldiers in military reserve with changes in health and physical condition indicates insufficient level of their health which has a negative impact on their capability and gradually on their fitness for military service. Priorities of changes in organization of the process of completion by human resources of the soldiers' military reserve in the Armed Forces of Ukraine during their transition towards professional army have been defined, to include optimization of criteria of fitness for military service.

    The ShotSpotter Gunshot Location System® has a flexible architecture that employs a wireless network of sensors mounted on buildings, vehicles, or soldiers. These distributed arrays with redundant acoustic paths combine audio time of arrival and/or angle of arrival from multiple sensors to calculate locations in challenging environments with obstructions or reflections. Muzzle and bullet sounds can be used depending on the proximity of the sensors to the bullet trajectory. Large array geometries allow not only close-range sniper detection but also wide-area situational awareness of enemy weapon activity. Examples of acoustic detections are presented in this paper using data from a combination of fixed and mobile sensors.

    This article describes the application of transference-focused psychotherapy (TFP) to the treatment of former child soldiers suffering from dissociative identity disorder. It focuses on the problems with aggression faced in psychotherapy. TFP provides a psychodynamic, object relations model to understand the aggression arising in psychotherapy, focusing on the transference and countertransference in the here and now of the therapeutic relationship. Aggression is considered an essential and vital inner dynamic aimed at autonomy, distancing, and the prevention of injury and dependency. In extremely traumatized patients there may be aggressive and oppressive inner parts that want total control-identifying with childhood aggressors-thus avoiding vulnerability. According to TFP it is vital that this aggression is addressed as belonging to the patients themselves in order to reach some form of integration, balance, and health. This is illustrated in a case description. PMID:23406222

    There can be substantial negative consequences for insects colonizing a resource in the presence of competitors. We hypothesized that bacteria, associated with an oviposition resource and the insect eggs deposited on that resource, serve as a mechanism regulating subsequent insect attraction, colonization, and potentially succession of insect species. We isolated and identified bacterial species associated with insects associated with vertebrate carrion and used these bacteria to measure their influence on the oviposition preference of adult black soldier flies which utilizes animal carcasses and is an important species in waste management and forensics. We also ascertained that utilizing a mixture of bacteria, rather than a single species, differentially influenced behavioral responses of the flies, as did bacterial concentration and the species of fly from which the bacteria originated. These studies provide insight into interkingdom interactions commonly occurring during decomposition, but not commonly studied. PMID:23995019

    From 2004 to 2008, the suicide rate among US Army Soldiers increased 80%, reaching a record high in 2008 and surpassing the civilian rate for the first time in recorded history. In recent years, the rate of Army suicides rose again; the year 2012 reflects the highest rate of military suicides on record. There is a need to assess current behavioral health practices to identify both effective and ineffective practices, and to adapt services to meet the needs of the Army behavioral health patient population. This paper discusses a process improvement initiative developed in an effort to improve clinical processes for suicide risk mitigation in an Army behavioral health clinic located in the catchment area of the US Army Southern Regional Medical Command.

    The purpose of this investigation was to evaluate U.S. Army soldiers who presented to the plastic surgery service with the inability to properly wear a government-issued Kevlar field helmet because of their prominent ear deformity. Between September 2000 and April 2002, four patients with prominent ears and helical rim skin abrasions with breakdown attributable to abutment from their helmets underwent open otoplasty with conchal bowl resection via a posterior approach. Symptomatic relief and cosmetic improvement were obtained, with no incidence of complications or recurrence during the follow-up period, which ranged from 9 to 22 months. All patients were able to wear their Army-issued Kevlar helmets without difficulty after surgery. Otoplasty is an effective, reliable procedure that has now been performed to alleviate symptoms in an otherwise asymptomatic patient population.

    Although substance abuse has consistently been linked to child maltreatment, no study to date has described the extent of substance abuse among child maltreatment offenders within the military. Analysis of U.S. Army data on all substantiated incidents of parental child maltreatment committed between 2000 and 2004 by active duty soldiers found that 13% of offenders were noted to have been abusing alcohol or illicit drugs at the time of their child maltreatment incident. The odds of substance abuse were increased for offenders who committed child neglect or emotional abuse, but were reduced for child physical abuse. The odds of offender substance abuse nearly tripled in child maltreatment incidents that also involved co-occurring spouse abuse. Findings include a lack of association between offender substance abuse and child maltreatment recurrence, possibly because of the increased likelihood of removal of offenders from the home when either substance abuse or spouse abuse were documented.

    This is the first prospective study to investigate psychosocial adjustment in male and female former child soldiers (ages 10-18; n = 156, 12% female). The study began in Sierra Leone in 2002 and was designed to examine both risk and protective factors in psychosocial adjustment. Over the 2-year period of follow-up, youth who had wounded or killed others during the war demonstrated increases in hostility. Youth who survived rape not only had higher levels of anxiety and hostility but also demonstrated greater confidence and prosocial attitudes at follow-up. Of the potential protective resources examined, improved community acceptance was associated with reduced depression at follow-up and improved confidence and prosocial attitudes regardless of levels of violence exposure. Retention in school was also associated with greater prosocial attitudes.

    It is widely recognized that military service during wartime can take a toll on a soldier's psychological health. Recent work has revealed effects on the families left behind as well, as reflected, for example, in an increase in child abuse and neglect in these families. My interest in studying the transgenerational transmission of trauma led me to offer the National Guard a pro bono group therapy for women whose husbands had been deployed overseas. A slightly unorthodox approach paved the way not only to group treatment but, ultimately, individual treatment for these women and their children. My hope is that this work can serve as a model for other therapists who share my interest in treating the intergenerational transmission of trauma by implementing group and mother-child psychotherapy.

    Current methods for mass-rearing black soldier flies, Hermetia illucens (L.) (Diptera: Stratiomyidae), in the laboratory are dependent on sunlight. Quartz-iodine lamps and rare earth lamps were examined as artificial light sources for stimulating H. illucens to mate and lay eggs. Sunlight was used as the control. Adults in the quartz-iodine lamp treatment had a mating rate of 61% of those in the sunlight control. No mating occurred when the rare earth lamp was used as a substitute. Egg hatch for the quartz-iodine lamp and sunlight treatments occurred in approximately 4 days, and the hatch rate was similar between these two treatments. Larval and pupal development under these treatments required approximately 18 and 15 days at 28°° C, respectively. Development of methods for mass rearing of H. illucens using artificial light will enable production of this fly throughout the year without investing in greenhouse space or requiring sunlight.

    Termite soldiers produce a vibratory alarm signal to warn conspecific workers. This study recorded and characterized the alarm signals of Coptotermes acinaciformis (Froggatt) (Isoptera: Rhinotermitidae) and then investigated the effect of playing these recorded alarm signals on C. acinaciformis feeding activity. Foraging groups of termites were offered paired wooden blocks: either one block, continuously stimulated with a vibratory alarm signal, paired with a nonstimulated block (the alarm treatment), continuously stimulated with a pink noise signal, paired with a nonstimulated block (control for nonspecific vibrations) or two nonstimulated blocks (control for environmental effects), for 4 wk. The amount of wood eaten in the blocks stimulated by the alarm signals was significantly less than the paired nonstimulated blocks, while there seemed to be no preference in the case of the pink noise playback or control for direction. Importantly, the termites seemed not to have adapted to the recorded alarm signal over the 4-wk duration of the experiment, unlike previous studies using nonbiologically derived signals.
