Context High rates of alcohol misuse after deployment have been reported among personnel returning from past conflicts, yet investigations of alcohol misuse after return from the current wars in Iraq and Afghanistan are lacking. Objectives To determine whether deployment with combat exposures was associated with new-onset or continued alcohol consumption, binge drinking, and alcohol-related problems. Design, Setting, and Participants Data were from Millennium Cohort Study participants who completed both a baseline (July 2001 to June 2003; n=77 047) and follow-up (June 2004 to February 2006; n=55 021) questionnaire (follow-up response rate=71.4%). After we applied exclusion criteria, our analyses included 48 481 participants (active duty, n=26 613; Reserve or National Guard, n=21 868). Of these, 5510 deployed with combat exposures, 5661 deployed without combat exposures, and 37 310 did not deploy. Main Outcome Measures New-onset and continued heavy weekly drinking, binge drinking, and alcohol-related problems at follow-up. Results Baseline prevalence of heavy weekly drinking, binge drinking, and alcohol-related problems among Reserve or National Guard personnel who deployed with combat exposures was 9.0%, 53.6%, and 15.2%, respectively; follow-up prevalence was 12.5%, 53.0%, and 11.9%, respectively; and new-onset rates were 8.8%, 25.6%, and 7.1%, respectively. Among active-duty personnel, new-onset rates were 6.0%, 26.6%, and 4.8%, respectively. Reserve and National Guard personnel who deployed and reported combat exposures were significantly more likely to experience new-onset heavy weekly drinking (odds ratio [OR], 1.63; 95% confidence interval [CI], 1.36–1.96), binge drinking (OR, 1.46; 95% CI, 1.24–1.71), and alcohol-related problems (OR, 1.63; 95% CI, 1.33–2.01) compared with nondeployed personnel. The youngest members of the cohort were at highest risk for all alcohol-related outcomes. Conclusion Reserve and National Guard personnel and younger service members who deploy with reported combat exposures are at increased risk of new-onset heavy weekly drinking, binge drinking, and alcohol-related problems.

2016-02-01

Contamination susceptibility, water usage, and inability to utilize 5-carbon sugars and disaccharides are among the major obstacles in industrialization of sustainable biorefining. Extremophilic thermophiles and acidophiles are being researched to combat these problems, but organisms which answer all the above problems have yet to emerge. Here, we present engineering of the unexplored, extreme alkaliphile Bacillus marmarensis as a platform for new bioprocesses which meet all these challenges. With a newly developed transformation protocol and genetic tools, along with optimized RBSs and antisense RNA, we engineered B. marmarensis to produce ethanol at titers of 38 g/l and 65% yields from glucose in unsterilized media. Furthermore, ethanol titers and yields of 12 g/l and 50%, respectively, were produced from cellobiose and xylose in unsterilized seawater and algal-contaminated wastewater. As such, B. marmarensis presents a promising approach for the contamination-resistant biorefining of a wide range of carbohydrates in unsterilized, non-potable seawater.

Highlights: • Up-cycling one type of pollution i.e. plastic waste and successfully using it to combat the other type of pollution i.e. oil spill. • Synthesized oil sorbent that has extremely high oil uptake of 90 g/g after prolonged dripping of 1 h. • Synthesized porous oil sorbent film which not only facilitates in oil sorption but also increases the affinity between sorbent and oil by means of adhesion. - Abstract: Thermoplastic polymers (such as polypropylene, polyethylene, polyethylene terephthalate (PET) and high density polyethylene (HDPE)) constitute 5–15% of municipal solid waste produced across the world. A huge quantity of plasticmore » waste is disposed of each year and is mostly either discarded in landfills or incinerated. On the other hand, the usage of synthetic polymers as oil sorbents, in particular, polyolefins, including polypropylene (PP), and polyethylene (PE) are the most commonly used oil sorbent materials mainly due to their low cost. However, they possess relatively low oil absorption capacities. In this work, we provide an innovative way to produce a value-added product such as oil-sorbent film with high practical oil uptake values in terms of g/g from waste HDPE bottles for rapid oil spill remedy.« less

The Effects of Alcohol Problems, PTSD, and Combat Exposure on Nonphysical and Physical Aggression Among Iraq and Afghanistan War Veterans

PubMed Central

Stappenbeck, Cynthia A.; Hellmuth, Julianne C.; Simpson, Tracy; Jakupcak, Matthew

2014-01-01

Aggression among combat veterans is of great concern. Although some studies have found an association between combat exposure and aggressive behavior following deployment, others conclude that aggression is more strongly associated with symptoms of posttraumatic stress disorder (PTSD), and that alcohol misuse may influence this association. Many of these studies have assessed aggression as a single construct, whereas the current study explored both nonphysical aggression only and physical aggression in a sample of Iraq and Afghanistan war veterans (N = 337; 91% male). We found that alcohol problems interacted with PTSD symptom severity to predict nonphysical aggression only. At low levels of PTSD symptoms, veterans with alcohol problems were more likely to perpetrate nonphysical aggression only, as compared with no aggression, than veterans without an alcohol problem. There was no difference in the likelihood of nonphysical aggression only between those with and without alcohol problems at high levels of PTSD symptoms. The likelihood of nonphysical aggression only, as compared with no aggression, was also greater among younger veterans. Greater combat exposure and PTSD symptom severity were associated with an increased likelihood of perpetrating physical aggression, as compared with no aggression. Ethnic minority status and younger age were also associated with physical aggression, as compared with no aggression. Findings suggest that a more detailed assessment of veterans’ aggressive behavior, as well as their alcohol problems and PTSD symptoms, by researchers and clinicians is needed in order to determine how best to intervene.

1996-04-01

Self-reported physical health status of Australian Vietnam veterans was determined 20-25 years after the war and its relation to combat was investigated. An epidemiological cohort study of a simple random sample of Army veterans posted to Vietnam between 1964 and 1972 was conducted with personal interviews using the Australian Bureau of Statistics Health Interview Survey questionnaire to compare veterans with the Australian population and a 21-item combat exposure index used to measure the relationship of combat to physical health. Veterans reported greater health service usage and more recent health actions than population expectations. They also reported excess health problems in almost all recent illness disease categories except endocrine conditions and cardiovascular conditions; only 6 of 37 chronic disease groups were not elevated compared to the population. Adjustment for non-response changed estimates only slightly. Combat exposure was significantly related to reports of recent and chronic mental disorders, recent hernia and chronic ulcer, recent eczema and chronic rash, deafness, chronic infective and parasitic disease, chronic back disorders and symptoms, signs and ill-defined conditions. Combat exposure may have significantly increased reports of only some health problems. A general position to complain as a result of psychological conditions due to combat is not consistent with the lack of relationship between combat and reports of physical conditions.

The goal of this work was to examine associations among childhood trauma, combat trauma, and substance use (alcohol problems, frequent heavy drinking [FHD], current cigarette smoking, and current/lifetime drug use) and the interaction effects of childhood trauma and combat exposure on those associations among National Guard/reserve soldiers. Participants (N = 248) completed an electronic survey asking questions about their military experiences, physical and mental health, and substance use. Childhood trauma and combat exposure were examined jointly in regression models, controlling for age, marital satisfaction, and number of deployments. Childhood trauma was associated with current drug use (trend level, odds ratio [OR] = 1.44, 95% confidence interval [CI]: 0.97, 2.14; P = .072) in the main effect model; however, there was not a significant interaction with combat. Combat exposure had a significant interaction with childhood trauma on alcohol problems (b = -0.56, 95% CI: -1.12, -0.01; P = .048), FHD (b = -0.27, 95% CI: -0.47, -0.08; P = .007), and lifetime drug use (OR = 1.78, 95% CI: 1.04, 3.04; P = .035). There were no associations with either of the trauma measures and current cigarette smoking. These results demonstrate that childhood and combat trauma have differential effects on alcohol use, such that combat trauma may not add to the effect on alcohol use in those with greater child maltreatment but may contribute to greater alcohol use among those with low child maltreatment. As expected, childhood and combat trauma had synergistic effects on lifetime drug use. Screening for multiple types of trauma prior to enlistment and/or deployment may help to identify at-risk individuals and allow time for early intervention to prevent future adverse outcomes.

We examined two groups of combat veterans, one with post-traumatic stress disorder (PTSD) (n = 27) and another without PTSD (n = 16), using an emotional Stroop task (EST) with word lists matched across a series of lexical variables (e.g. length, frequency, neighbourhood size, etc.). Participants with PTSD exhibited a strong EST effect (longer colour-naming latencies for combat-relevant words as compared to neutral words). Veterans without PTSD produced no such effect, t < .918, p > .37. Participants with PTSD then completed eight sessions of attention training (Attention Control Training or Attention Bias Modification Training) with a dot-probe task utilising threatening and neutral faces. After training, participants-especially those undergoing Attention Control Training-no longer produced longer colour-naming latencies for combat-related words as compared to other words, indicating normalised attention allocation processes after treatment.

More than 15 000 French soldiers are continuously deployed abroad. Along with combat-related injuries, they are exposed to non-combat-related diseases with an underestimated burden. Our objectives were to assess the incidence and impact of health problems on their operating capacity. A prospective multicenter study was conducted over more than three months in Lebanon, Côte d'Ivoire and Afghanistan including exclusively French soldiers. We collected 4349 consultations (Afghanistan {n = 719}, Lebanon {n = 1401} and Côte d'Ivoire {n = 2229}) encompassing 4600 health problems. Injuries (21%), diarrhea (19%), dermatoses (17.5%) and respiratory tract infections (10.45%) were the most frequent health issues. Infectious diseases represented 41% of all health problems. Almost nine out of ten patients were managed as outpatients. Ten combat-related deaths were observed. We reported 68 (1.5%) medical repatriations of which 28 and 26 were psychiatric and trauma cases respectively. Partial or complete incapacity was estimated 724 days/1000 men/month. Etiological spectrum was similar in all three countries however, the incidence of diarrhea (p < 0.05) as well as inpatient management and medical evacuation rates were higher (p < 0.0001) in Afghanistan. There was a wide spectrum of health problems occurring during military deployments with a predominance of common infections. Non-combat-related pathology represented an important burden for the loss of operating capacity. Copyright © 2014 Elsevier Ltd. All rights reserved.

New combat laser and ballistic eye protection goggles

NASA Astrophysics Data System (ADS)

Belkin, Michael

1996-04-01

Up to 10% of all combat casualties involve eye injuries which are becoming more severe, bilateral and likely to lead to a retained intraocular foreign body. The modern battlefield is permeated with laser radiation from range finders, target designators and perhaps laser weapons aimed at producing visual incapacitation. In future wars, therefore, the likelihood of eye injuries is very high. We sought to devise means to protect the eye from military relevant injurious agents. Almost all ballistic injuries can be prevented by using polycarbonate goggles. They must not, however, interfere with the soldier's functions such as the use of binoculars or limit his visual fields. These problems are not insurmountable and we shall demonstrate new goggles design which we believe will be acceptable to the troops. The solution to laser protection is more difficult. For that purpose the goggles include outserts filters for various groups of laser wavelengths. The soldier will use the appropriate filter according to a reading from a laser detector which will indicate which filter is protective against the wavelength detected.

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

2017-06-01

The study of organic and psychological response during combat situations has been poorly reported despite its importance for soldiers training and specific instruction, so it was proposed as aim of the present investigation to analyze the effect of a tactical parachute simulated jump in psycho-physiological response of paratroopers' warfighters during an urban combat simulation. 19 male paratroopers (31.9 ± 6.2 year old; 173.6 ± 5.3 cm; 73.8 ± 8.3 Kg) of the Spanish Army were divided in two groups: parachute jump group (n:11) that conducted a simulated parachute jump and a urban combat maneuver and a non-parachute jump group (n:8) that only conducted an urban combat maneuver. We analyzed before and after the maneuver the rated perceived exertion, legs strength manifestation, blood lactate, cortical activation, heart rate variability, blood oxygen saturation and pressure, skin temperature, fine motor skills, and anxiety state. A tactical parachute simulated jump prior to an urban combat maneuver produce significantly (p < 0.05) higher heart rate and decrease in specific fine motor skills in comparison with no jump situation in professional Army paratroopers. Independently of the parachute jump, an urban combat maneuver produces a significant increase in rated perceived exertion, blood lactate, heart rate, legs strength, sympathetic modulation and anxiety response as well as a significant decrease in blood oxygen saturation and parasympathetic modulation.

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

PubMed

Rodrigues, Camila S; Renshaw, Keith D

2010-10-01

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

Furthermore, ethanol titers and yields of 12 g/l and 50%, respectively, were produced from cellobiose and xylose in unsterilized seawater and algal-contaminated wastewater. As such, B. marmarensis presents a promising approach for the contamination-resistant biorefining of a wide range of carbohydrates in unsterilized, non-potable seawater. PMID:26831574

Enhancing US-Japan Cooperation to Combat Antimicrobial Resistance

PubMed Central

2014-01-01

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

U.S. Service Member Deployment in Response to the Ebola Crisis: The Psychological Perspective.

Sipos, Maurice L; Kim, Paul Y; Thomas, Stephen J; Adler, Amy B

2018-03-01

In the fall of 2014, the United States and other nations responded to the worst outbreak of the Ebola virus disease in history. As part of this effort, U.S. service members deployed to West Africa to support a spectrum of activities that did not involve direct patient care. Although previous studies identified the psychological impact of responding to an outbreak, these studies were limited to retrospective data, small sample sizes, and medical personnel. The goals of the present study were to (a) document the mental health and well-being of troops deploying in response to an infectious disease outbreak; (b) identify their stressors, attitudes toward deployment, and health risk concerns; and (c) understand the role of combat experience in adjusting to these types of missions. Study participants at both pre- and during deployment were active duty U.S. soldiers in a combat aviation battalion from a large U.S. military installation. U.S. soldiers were surveyed (n = 251) 3 wk before deploying to Liberia (October 2014) and surveyed again during their deployment (February 2015; n = 173). Participants were primarily male (86.1%), junior ranking (56.0%), and just over half had previous combat deployment experience (51.2%). Surveys were anonymous and not linked to one another over time. Overall rates of mental health problems were low (2.4% at pre-deployment and 5.8% during deployment), whereas sleep problems were reported by 4.9% at pre-deployment and 12% during deployment. At pre-deployment, top stressors focused on health threats; fewer stressors were reported during deployment. Soldiers were relatively less concerned about contracting Ebola than other more prevalent diseases. Soldiers with combat experience reported more somatic and sleep problems at pre-deployment than those without previous combat experience. There were no significant differences during deployment between those with and without previous combat experience. Overall, a small proportion of respondents reported significant rates of mental health problems. In contrast, sleep problems were reported by 12% during deployment. In terms of attitudes toward the mission, the vast majority reported that they knew what to do to protect themselves from disease and that they understood the potential risk involved. The study also confirmed previous findings that soldiers with previous combat experience had more somatic symptoms at pre-deployment than those without, although this distinction appeared limited to the pre-deployment phase. Results can be used to address anxiety by personnel during pre-deployment and to inform leadership preparing personnel to deploy in response to future infectious disease outbreaks.

Zhang, Bo; Duan, Haibin

2017-01-01

Three-dimension path planning of uninhabited combat aerial vehicle (UCAV) is a complicated optimal problem, which mainly focused on optimizing the flight route considering the different types of constrains under complex combating environment. A novel predator-prey pigeon-inspired optimization (PPPIO) is proposed to solve the UCAV three-dimension path planning problem in dynamic environment. Pigeon-inspired optimization (PIO) is a new bio-inspired optimization algorithm. In this algorithm, map and compass operator model and landmark operator model are used to search the best result of a function. The prey-predator concept is adopted to improve global best properties and enhance the convergence speed. The characteristics of the optimal path are presented in the form of a cost function. The comparative simulation results show that our proposed PPPIO algorithm is more efficient than the basic PIO, particle swarm optimization (PSO), and different evolution (DE) in solving UCAV three-dimensional path planning problems.

Military Combat Deployments and Substance Use: Review and Future Directions

PubMed Central

LARSON, MARY JO; WOOTEN, NIKKI R.; ADAMS, RACHEL SAYKO; MERRICK, ELIZABETH L.

2012-01-01

Iraq and Afghanistan veterans experience extreme stressors and injuries during deployments, witnessing and participating in traumatic events. The military has organized prevention and treatment programs as a result of increasing suicides and posttraumatic stress disorder among troops; however, there is limited research on how to intervene with alcohol misuse and drug use that accompany these problems. This review presents statistics about post-deployment substance use problems and comorbidities, and discusses the military’s dual role in 1) enforcing troop readiness with its alcohol and drug policies and resiliency-building programs, and 2) seeking to provide treatment to troops with combat-acquired problems including substance abuse.

Saleem, Junaid; Ning, Chao; Barford, John; McKay, Gordon

2015-10-01

Thermoplastic polymers (such as polypropylene, polyethylene, polyethylene terephthalate (PET) and high density polyethylene (HDPE)) constitute 5-15% of municipal solid waste produced across the world. A huge quantity of plastic waste is disposed of each year and is mostly either discarded in landfills or incinerated. On the other hand, the usage of synthetic polymers as oil sorbents, in particular, polyolefins, including polypropylene (PP), and polyethylene (PE) are the most commonly used oil sorbent materials mainly due to their low cost. However, they possess relatively low oil absorption capacities. In this work, we provide an innovative way to produce a value-added product such as oil-sorbent film with high practical oil uptake values in terms of g/g from waste HDPE bottles for rapid oil spill remedy.

2015-01-01

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

Depression in Female Veterans Returning from Deployment: The Role of Social Factors.

Sairsingh, Holly; Solomon, Phyllis; Helstrom, Amy; Treglia, Dan

2018-03-01

Women are serving in the armed forces and deployed to areas of conflict in increasing numbers. Problems such as depressive symptoms and risks related to combat exposure can have negative effects on adjustment following service; understanding the relationship between these problems may contribute to strategies providers can use to facilitate healthy adjustment after deployment. The purpose of this study is to examine social factors as they relate to mental health adjustment, namely depressive symptoms among female veterans who served in Iraq and Afghanistan as part of Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OND). We hypothesized that combat exposure would predict higher levels of depressive symptoms and that social support would moderate the relationship between combat exposure and depression. In a cross-sectional design, 128 female Operation Enduring Freedom/Operation Iraqi Freedom/Operation New Dawn veterans completed an online survey about combat experience, social support, depression, demographic characteristics, and behavioral health symptom history. We conducted multiple regression analyses to examine linear and moderating relationships. There was no significant relationship between combat exposure and depression; social support did not significantly moderate the relationship between combat exposure and depression. However, higher levels of social support and financial comfort were significantly related to lower levels of depression. This study highlights the role of social factors, specifically social support and perceived financial status, as potential barriers to healthy emotional readjustment following deployment. These findings suggest that it may be beneficial for mental health providers to screen female veterans and refer them to appropriate services to reduce financial stressors and strengthen their use of social support. More research should continue to examine more fully the impact of combat exposure on female service members' mental health and work to isolate the factors most strongly related to depression.

Research on air and missile defense task allocation based on extended contract net protocol

2017-10-01

Based on the background of air and missile defense distributed element corporative engagement, the interception task allocation problem of multiple weapon units with multiple targets under network condition is analyzed. Firstly, a mathematical model of task allocation is established by combat task decomposition. Secondly, the initialization assignment based on auction contract and the adjustment allocation scheme based on swap contract were introduced to the task allocation. Finally, through the simulation calculation of typical situation, the model can be used to solve the task allocation problem in complex combat environment.

Analysis of the causes of medical evacuation of injured and sick soldiers of the Polish Military Contingent in the Islamic State of Afghanistan taking part in International Security Assistance Force operations.

2012-04-01

Military casualties in Afghanistan arise in part from climatic and natural conditions that are difficult for European soldiers to endure, as well as from intense guerrilla combat with mass use of IEDs (improvised explosive devices), thus posing numerous and diverse medical problems requiring evacuation to the home country. A search of the literature revealed no comprehensive studies of the causes of medical evacuation from this theater of operations. This article is a review of medical reports of the Polish Military Contingent taking part in Operation Enduring Freedom during the period from 01 January 2010 to 31 December 2011, including an analysis of causes of all ROLE 4 medical evacuations (to the military base in Germany or to the home country). As many as 565 (5.49%) of the total of 10 294 contingent soldiers were evacuated during the analyzed period. Of these, 29% of evacuation cases were due to combat injuries, 23% to complications of respiratory tract infection, 11% to mental health problems, 11% to chronic neuralgias, 12% to complications of acute gastrointestinal infections, 4% to non-combat injuries, 3% to dental and maxillofacial problems, 2% to dermatological problems and 2% to leishmaniasis. The remaining causes included chronic organic/systemic diseases manifested during service. The main causes of medical evacuations to the home country were the consequences of combat injuries, mainly due to IED attacks. Appropriate diagnosis and early treatment of infections is also an important problem in the face of a significant number of complications resulting in evacuation of soldiers to their home country.

2017-01-01

This study tested the role of affect lability and disinhibition in mediating associations between PTSD symptoms and two forms of alcohol-related problems, dependence syndrome symptoms (e.g., impaired control over consumption) and conduct problems (e.g., assault, risk behaviors). Genotype at the serotonin transporter linked polymorphic region (5-HTTLPR) was hypothesized to moderate associations between traumatic stress and PTSD symptoms. In addition, the study tested whether childhood traumatic stress moderated associations between combat trauma and PTSD symptoms. Participants were 270 OIF/OEF/OND veterans. The hypothesized model was largely supported. Participants with the low expression alleles of 5-HTTLPR (S or L G ) exhibited stronger associations between childhood (but not combat) traumatic stress and PTSD symptoms. Affect lability mediated the associations between PTSD symptoms and alcohol dependence symptoms. Behavioral disinhibition mediated associations between PTSD symptoms and conduct related problems. Conditional indirect effects indicated stronger associations between childhood traumatic stress and lability, behavioral disinhibition, alcohol consumption, AUD symptoms, and associated conduct problems via PTSD symptoms among those with the low expression 5-HTTLPR alleles. However, interactions between combat trauma and either childhood trauma or genotype were not significant. The results support the hypothesis that affect lability and behavioral disinhibition are potential intermediate traits with distinct associations with AUD and associated externalizing problems.

Delgado-Moreno, Rosa; Robles-Pérez, José Juan; Clemente-Suárez, Vicente Javier

2017-08-01

The present research aimed to analyze the effect of combat stress in the psychophysiological response and attention and memory of warfighters in a simulated combat situation. Variables of blood oxygen saturation, heart rate, blood glucose, blood lactate, body temperature, lower body muscular strength manifestation, cortical arousal, autonomic modulation, state anxiety and memory and attention through a postmission questionnaire were analyzed before and after a combat simulation in 20 male professional Spanish Army warfighters. The combat simulation produces a significant increase (p < 0.05) in explosive leg strength, rated perceived exertion, blood glucose, blood lactate, somatic anxiety, heart rate, and low frequency domain of the HRV (LF) and a significant decrease of high frequency domain of the heart rate variability (HF). The percentage of correct response in the postmission questionnaire parameters show that elements more related with a physical integrity threat are the most correctly remembered. There were significant differences in the postmission questionnaire variables when participants were divided by the cortical arousal post: sounds no response, mobile phone correct, mobile phone no response, odours correct. The correlation analysis showed positive correlations: LF post/body temperature post, HF post/correct sound, body temperature post/glucose post, CFFTpre/lactate post, CFFT post/wrong sound, glucose post/AC pre, AC post/wrong fusil, AS post/SC post and SC post/wrong olfactory; and negative correlations: LF post/correct sound, body temperature post/lactate post and glucose post/lactate post. This data suggest that combat stress actives fight-flight system of soldiers. As conclusion, Combat stress produces an increased psychophysiological response that cause a selective decrease of memory, depending on the nature, dangerous or harmless of the objects.

2013-04-01

Research involving military service members has shown a strong relationship between combat experiences and increased risk for posttraumatic stress disorder (PTSD) and other mental health problems. Comparatively little research has examined the relationship between combat experiences, PTSD, aggression, and unethical conduct on the battlefield, although news stories sometimes suggest links between unethical conduct and disorders such as PTSD. This study systematically examined whether unethical conduct is a proxy for aggression and whether specific combat experiences and PTSD are independently associated with unethical behavior. The results of this study indicate that aggression (β = 0.30) and specific combat experiences (particularly, witnessing war atrocities [β = 0.14] and fighting [β = 0.13]) are much more strongly associated with unethical conduct than is PTSD (β = 0.04).

Some problems associated with war experience in men of the Vietnam generation.

PubMed

Yager, T; Laufer, R; Gallops, M

1984-04-01

A national sample of men who were of military age during the Vietnam War (n = 1,342) was interviewed six to 15 years after veterans in the sample had left the service. Our findings showed that violent experiences in war were associated with a variety of behavioral and emotional problems. When preservice background factors were statistically controlled, combat exposure showed an association with arrests and convictions (generally for nonviolent offenses), with drinking, and with symptoms of traumatic stress. Participants in atrocities reported more stress symptoms and greater use of heroin and marijuana than did other veterans. Veterans who experienced no combat and did not take part in atrocities, however, did not differ appreciably from nonveterans. Not all men who experienced combat or took part in atrocities reported personal difficulties; almost three fourths of heavy-combat veterans were not arrested after the service. Tape recorded responses of the ten blacks and 18 whites who took part in atrocities suggested that soldiers' emotional responses may have been determined by their ability or inability to dehumanize the victims. Future research would benefit from a closer coordination of clinical and epidemiologic approaches.

2018-01-01

Aedes aegypti and Aedes albopictus mosquitoes are responsible for the transmission of diseases such as dengue fever, yellow fever, chikungunya fever, zika virus fever, some of which can cause irreversible central nervous system problems and death. This study investigates what technologies are being used for combatting and monitoring the Aedes mosquitoes and to propose joining these technologies into a single and complete solution using the Smart Cities concept. A search for newscasts on Google and mobile apps in app stores were performed to identify technological solutions for combat to Aedes mosquitoes. Also, a model for joint technology was proposed. Results identified the following technologies: 170 software, two sensors, two drones, one electronic device, ten mosquito traps/lures, seven biological tools, six biotechnologies, and eight chemical formulations. Technological resources and adoption of preventive measures by the population could be a useful method for the mosquito control. Examples include a georeferenced model for identification and examination of larvae, application of chemical/biological products, real-time mapping, sending of educational materials via email or social media for the population, and alerts to health professionals in the zones of combat/risk. In combination, these technologies may indicate a better solution to the current problem.

Difficulty understanding speech in noise by the hearing impaired: underlying causes and technological solutions.

PubMed

Healy, Eric W; Yoho, Sarah E

2016-08-01

A primary complaint of hearing-impaired individuals involves poor speech understanding when background noise is present. Hearing aids and cochlear implants often allow good speech understanding in quiet backgrounds. But hearing-impaired individuals are highly noise intolerant, and existing devices are not very effective at combating background noise. As a result, speech understanding in noise is often quite poor. In accord with the significance of the problem, considerable effort has been expended toward understanding and remedying this issue. Fortunately, our understanding of the underlying issues is reasonably good. In sharp contrast, effective solutions have remained elusive. One solution that seems promising involves a single-microphone machine-learning algorithm to extract speech from background noise. Data from our group indicate that the algorithm is capable of producing vast increases in speech understanding by hearing-impaired individuals. This paper will first provide an overview of the speech-in-noise problem and outline why hearing-impaired individuals are so noise intolerant. An overview of our approach to solving this problem will follow.

Although military personnel are trained for combat and peacekeeping operations, accumulating evidence indicates that deployment-related exposure to traumatic events is associated with mental health problems and mental health service use. To examine the relationships between combat and peacekeeping operations and the prevalence of mental disorders, self-perceived need for mental health care, mental health service use, and suicidality. Cross-sectional, population-based survey. Canadian military. A total of 8441 currently active military personnel (aged 16-54 years). The DSM-IV mental disorders (major depressive disorder, posttraumatic stress disorder, generalized anxiety disorder, panic disorder, social phobia, and alcohol dependence) were assessed using the World Mental Health version of the World Health Organization Composite International Diagnostic Interview, a fully structured lay-administered psychiatric interview. The survey included validated measures of self-perceived need for mental health treatment, mental health service use, and suicidal ideation. Lifetime exposure to peacekeeping and combat operations and witnessing atrocities or massacres (ie, mutilated bodies or mass killings) were assessed. The prevalences of any past-year mental disorder assessed in the survey and self-perceived need for care were 14.9% and 23.2%, respectively. Most individuals meeting the criteria for a mental disorder diagnosis did not use any mental health services. Deployment to combat operations and witnessing atrocities were associated with increased prevalence of mental disorders and perceived need for care. After adjusting for the effects of exposure to combat and witnessing atrocities, deployment to peacekeeping operations was not associated with increased prevalence of mental disorders. This is the first study to use a representative sample of active military personnel to examine the relationship between deployment-related experiences and mental health problems. It provides evidence of a positive association between combat exposure and witnessing atrocities and mental disorders and self-perceived need for treatment.

The presence of metal artefacts in computed tomography (CT) create issues in radiation oncology. The loss of anatomical information and incorrect Hounsfield unit (HU) values produce inaccuracies in dose calculations, providing suboptimal patient treatment. Metal artefact reduction (MAR) algorithms were developed to combat these problems. This study provides a qualitative and quantitative analysis of the "Smart MAR" software (General Electric Healthcare, Chicago, IL, USA), determining its usefulness in a clinical setting. A detailed analysis was conducted using both patient and phantom data, noting any improvements in HU values and dosimetry with the GE-MAR enabled. This study indicates qualitative improvements in severity of the streak artefacts produced by metals, allowing for easier patient contouring. Furthermore, the GE-MAR managed to recover previously lost anatomical information. Additionally, phantom data showed an improvement in HU value with GE-MAR correction, producing more accurate point dose calculations in the treatment planning system. Overall, the GE-MAR is a useful tool and is suitable for clinical environments.

Historical approaches to post-combat disorders.

Jones, Edgar

2006-04-29

Almost every major war in the last century involving western nations has seen combatants diagnosed with a form of post-combat disorder. Some took a psychological form (exhaustion, combat fatigue, combat stress reaction and post-traumatic stress disorder), while others were characterized by medically unexplained symptoms (soldier's heart, effort syndrome, shell shock, non-ulcer dyspepsia, effects of Agent Orange and Gulf War Syndrome). Although many of these disorders have common symptoms, the explanations attached to them showed considerable diversity often reflected in the labels themselves. These causal hypotheses ranged from the effects of climate, compressive forces released by shell explosions, side effects of vaccinations, changes in diet, toxic effects of organophosphates, oil-well fires or depleted-uranium munitions. Military history suggests that these disorders, which coexisted in the civilian population, reflected popular health fears and emerged in the gaps left by the advance of medical science. While the current Iraq conflict has yet to produce a syndrome typified by medically unexplained symptoms, it is unlikely that we have seen the last of post-combat disorders as past experience suggests that they have the capacity to catch both military planners and doctors by surprise.

Bacillus thuringiensis ( Bt ) is a Gram-positive, spore-forming, soil bacterium, which is very popular bio-control agent in agricultural and forestry. In general, B. thuringiensis secretes an array of insecticidal proteins including toxins produced during vegetative growth phase (such as secreted insecticidal protein, Sip; vegetative insecticidal proteins, Vip), parasporal crystalline δ-endotoxins produced during vegetative stationary phase (such as cytolytic toxin, Cyt; and crystal toxin, Cry), and β-exotoxins. Till date, a wide spectrum of Cry proteins has been reported and most of them belong to three-domain-Cry toxins, Bin-like toxin, and Etx_Mtx2-like toxins. To the best of our knowledge, neither Bt insecticidal toxins are exclusive to Bt nor all the strains of Bt are capable of producing insecticidal Bt toxins. The lacuna in their latest classification has also been discussed. In this review, the updated information regarding the insecticidal Bt toxins and their different mode of actions were summarized. Before applying the Bt toxins on agricultural field, the non-specific effects of toxins should be investigated. We also have summarized the problem of insect resistance and the strategies to combat with this problem. We strongly believe that this information will help a lot to the budding researchers in the field of modern pest control biotechnology.

Interactive psychoeducational group therapy in the treatment of authority problems in combat-related posttraumatic stress disorder.

PubMed

Lubin, H; Johnson, D R

2000-07-01

The use of Interactive Psychoeducational Group Therapy to ameliorate authority problems of veterans with combat-related posttraumatic stress disorder is described. Despite the common occurrence of authority problems in this population, and the degree of damage they have caused in family, work, and legal domains, they are rarely specifically targeted by treatment interventions. A conceptual framework linking psychological trauma with distortions in authority relations is presented, followed by the format, procedures, and case examples of this form of group therapy. By uncovering the distorted beliefs associated with traumatic schemas as they emerge in the group interaction, the group therapist can first help the clients question their assumptions about authority, and then explore more adaptive behaviors. The need to examine in greater detail the causes and impact of authority problems among clients with posttraumatic stress disorder is emphasized.

A differential game solution to the Coplanar tail-chase aerial combat problem

1976-01-01

Numerical results obtained in a simplified version of the one on one aerial combat problem are presented. The primary aim of the data is to specify the roles of pursuer and evader as functions of the relative geometry and of the significant physical parameters of the problem. Numerical results are given in a case in which the slower aircraft is more maneuverable than the faster aircraft. A third order dynamic model of the relative motion is described, for which the state variables are relative range, bearing, and heading. The ranges at termination are arbitary in the present version of the problem, so the weapon systems of both aircraft can be visualized as forward firing high velocity weapons, which must be aimed at the tail pipe of the evader. It was found that, for the great majority of the ralative geometries, each aircraft can evade the weapon system of the other.

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

Use of computerized neuropsychological testing to help determine fitness to return to combat operations when taking medication that can influence cognitive function.

PubMed

McLay, Robert; Spira, James; Reeves, Dennis

2010-12-01

Nowhere is it more important to maintain peek mental functioning than in a combat zone. Conditions ranging from pain to head injury to post-traumatic stress disorder can cause impairments in neuropsychological function and place service members at risk. Medications can sometimes help alleviate these problems, but also have the risk of further slowing cognitive function or impairing reaction time. Standard methods of neuropsychological testing are often not available in a combat environment. New technologies are being advanced that can allow portable, computerized neuropsychological testing to be performed at almost any location. We present a case that demonstrates how the use of such handheld technology can assist a military physician in assessing the influence of medication on reaction time and in determining if and when a service member is ready to return to combat.

An automated methodology development. [software design for combat simulation

NASA Technical Reports Server (NTRS)

Hawley, L. R.

1985-01-01

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

The Afghan military theatre is specifically marked by guerilla operations and massive use of IEDs (improvised explosive devices) that pose new types of threats for their victims. At the same time, the relevant literature contains only a single, fragmentary analysis on injuries suffered by soldiers serving in the Afghan mission. This is a review of medical reports of the Polish Military Contingent deployed within Operation Enduring Freedom, from 1 January 2010 to 31 December 2011; the analysis includes all cases of combat and non-combat injuries in terms of their causes. In the period under analysis, 380 Polish soldiers were reported injured; 87.1% of cases were combat and 12.9% non-combat injuries. The structure of injuries caused as a result of IED explosions was dominated by multiple limb injuries, associated most frequently with severe body cavities/spine injuries. In the case of other incidents, both combat and non-combat, the predominant consequences were single and, most commonly, less severe injuries. The average number of injuries suffered from IED attacks (3.37) was significantly higher than the number of injuries from other attacks (1.16), and higher than the number of non-combat injuries (1.43). IED attacks pose a serious medical problem, considering their high number and the severity of injuries they cause.

2016-04-01

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

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

In Asian culture, there is much stigmatization attached on having mental health problems and seeking help from a mental health expert. It is therefore, not surprising, that this stigmatization results in the refutation of the subsistence of a psychiatric problem in an individual and his family but also produces obstruction to help-seeking desires. To get a clear picture of the existence of psychiatric issues in the population, various research projects addressing psychiatric issues in children, women, and elderly are conducted both in Pakistan and India. A significant input has been taken from research conducted in India combating disaster management. In addition, public awareness programs are organized to provide information about common psychiatric disorders in children, adults, women, and the elderly.-Furthermore, psychiatric patients and their families are educated for the management of mental heath problems related to marriage, pregnancy, birth and hazards of smoking & substance abuse in young adults. Keeping in view the similarity in cultural background, treatment models, family structure, and psychosocial factors, collaborative research studies should be encouraged leading to improvement in psychiatric care of the patients both in India and Pakistan.

Towards a Research Agenda for Cyber Friendly Fire

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

Greitzer, Frank L.; Clements, Samuel L.; Carroll, Thomas E.

Historical assessments of combat fratricide reveal principal contributing factors in the effects of stress, degradation of skills due to continuous operations or sleep deprivation, poor situation awareness, and lack of training and discipline in offensive/defense response selection. While these problems are typically addressed in R&D focusing on traditional ground-based combat, there is also an emerging need for improving situation awareness and decision making on defensive/offensive response options in the cyber defense arena, where a mistaken response to an actual or perceived cyber attack could lead to destruction or compromise of friendly cyber assets. The purpose of this report is tomore » examine cognitive factors that may affect cyber situation awareness and describe possible research needs to reduce the likelihood and effects of "friendly cyber fire" on cyber defenses, information infrastructures, and data. The approach is to examine concepts and methods that have been described in research applied to the more traditional problem of mitigating the occurrence of combat identification and fratricide. Application domains of interest include cyber security defense against external or internal (insider) threats.« less

Acid Rain Contribution from Pesticide Distribution to Rice Farmers in Pati Regency

NASA Astrophysics Data System (ADS)

Qosim, Ahmad; Anies; Sunoko, Henna Rya

2018-02-01

Productivity rate of rice fields in Regency has been in a surplus condition annually. The fields have produced 7 to 8 tons per hectare, making the total annual rate of 600 tons. The regency, therefore, is considered to be capable of fulfilling its own need for rice and to contribute significantly to the rice needs in Central Java Province. Agriculture coexists with the presence of pesticides. While helping the farmers to combat the plant diseases, pesticides have still been greatly necessary by the local farmers. Distribution by means of transportation devices plays an important role for the dissemination of the pesticides from the producers to their end users. Problem arises due to emission produced during the transportation activities. Transportation emits SO2 as the major contributor to acid rain. To make worse, application in practice by the farmers also emit the similar substance. Annual use of pesticides in Pati Regency has reached 605 tons with SO2 emission of 13,697 kg. It is recommended that distribution management and selection of pesticides are performed by applying an integrated pest control in order to reduce the pesticide emission.

Stathi, Sofia; Tsantila, Katerina; Crisp, Richard J

2012-01-01

Research has demonstrated widespread negative attitudes held toward people with mental health problems. Our study investigated whether a new prejudice reduction technique, imagined intergroup contact (Crisp & Turner, 2009), could combat stigma against people with mental illness, and the mediating processes through which it may exert this beneficial effect. We found that compared to a control condition, participants who imagined a positive encounter with a schizophrenic person reported weakened stereotypes and formed stronger intentions to engage in future social interactions with schizophrenic people in general. Importantly, these intentions were formed due to reduced feelings of anxiety about future interactions. We discuss the implications of these findings for improving the social inclusion of people with mental health problems.

Talking with juvenile offenders about gay males and lesbians: implications for combating homophobia.

PubMed

Van de Ven, P

1995-01-01

Violence against gay males and lesbians, much of it perpetrated by young people, has emerged as a significant social problem. Thirty-one juvenile offenders were asked a series of structured questions in order to elucidate the functions their attitudes toward homosexuals serve. In addition, responses were examined for evidence of social-structural and cognitive variables which mediate offending behaviors. Juvenile offenders were found to hold attitudes toward homosexuals characterized by negativity, ambivalence, and defensiveness. These attitudes were maintained by particular myths and stereotypes about gay and lesbian culture, and were related to Opportunism, Impulsivity, Role-Taking Inability, and Disabilities in Social Problem Solving. Specific recommendations for combating homophobic attitudes and behaviors in juvenile offender populations are discussed.

Coplanar aerial combat is modeled with constant speeds and specified turn rates. The minimum capture radius which will always permit capture, regardless of the initial conditions, is calculated. This 'critical' capture radius is also the maximum range which the evader can guarantee indefinitely if the initial range, for example, is large. A composite barrier is constructed which gives the boundary, at any heading, of relative positions for which the capture radius is less than critical.

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

PubMed

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

2017-05-01

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

The main aim of this study was to assess the mental health status of the Navy Special Forces and regular forces three and a half years after the end of combat operations in mid 2009, and compare it with the findings in 2009. This cross sectional study was carried out in the Sri Lanka Navy (SLN), three and a half years after the end of combat operations. Representative samples of SLN Special Forces and regular forces deployed in combat areas were selected using simple random sampling. Only personnel who had served continuously in combat areas during the one year period prior to the end of combat operations were included in the study. The sample consisted of 220 Special Forces and 275 regular forces personnel. Compared to regular forces a significantly higher number of Special Forces personnel had experienced potentially traumatic events. Compared to the period immediately after end of combat operations, in the Special Forces, prevalence of psychological distress and fatigue showed a marginal increase while hazardous drinking and multiple physical symptoms showed a marginal decrease. In the regular forces, the prevalence of psychological distress, fatigue and multiple somatic symptoms declined and prevalence of hazardous drinking increased from 16.5% to 25.7%. During the same period prevalence of smoking doubled in both Special Forces and regular forces. Prevalence of PTSD reduced from 1.9% in Special Forces to 0.9% and in the regular forces from 2.07% to 1.1%. Three and a half years after the end of combat operations mental health problems have declined among SLN regular forces while there was no significant change among Special Forces. Hazardous drinking among regular forces and smoking among both Special Forces and regular forces have increased.

Effects of combat deployment on risky and self-destructive behavior among active duty military personnel.

2011-10-01

Although research has documented negative effects of combat deployment on mental health, few studies have examined whether deployment increases risky or self-destructive behavior. The present study addressed this issue. In addition, we examined whether deployment effects on risky behavior varied depending on history of pre-deployment risky behavior, and assessed whether psychiatric conditions mediated effects of deployment on risky behavior. In an anonymous survey, active duty members of the U.S. Marine Corps and U.S. Navy (N = 2116) described their deployment experiences and their participation in risky recreational activities, unprotected sex, illegal drug use, self-injurious behavior, and suicide attempts during three time frames (civilian, military pre-deployment, and military post-deployment). Respondents also reported whether they had problems with depression, anxiety, or PTSD during the same three time frames. Results revealed that risky behavior was much more common in civilian than in military life, with personnel who had not deployed, compared to those who had deployed, reporting more risky behavior and more psychiatric problems as civilians. For the current time period, in contrast, personnel who had deployed (versus never deployed) were significantly more likely to report both risky behavior and psychiatric problems. Importantly, deployment was associated with increases in risky behavior only for personnel with a pre-deployment history of engaging in risky behavior. Although psychiatric conditions were associated with higher levels of risky behavior, psychiatric problems did not mediate associations between deployment and risky behavior. Implications for understanding effects of combat deployment on active duty personnel and directions for future research are discussed. Published by Elsevier Ltd.

It is the position of the American Dietetic Association (ADA) that access to adequate amounts of safe, nutritious, and culturally appropriate food at all times is a fundamental human right. Hunger continues to be a worldwide problem of staggering proportions. The Association supports programs and encourages practices that combat hunger and malnutrition, produce food security, promote self-sufficiency, and are environmentally and economically sustainable. The Association is aware that hunger exists in a world of plenty and that poverty, gender inequity, ethnocentrism, racism, and the lack of political will are key constraints to solving the problems of global hunger and malnutrition. Recognizing that simplistic approaches are inadequate, the ADA identifies sustainable development as the long-term strategy to ending world hunger and achieving food security. Sustainable development requires political, economic, and social changes that include empowering the disenfranchised, widening access to assets and other resources, narrowing the gap between rich and poor, and adjusting consumption patterns so as to foster good stewardship of nature. Additionally, because the health status of future generations is related to the well-being of their mothers, achieving food security will also require increased access for women to education, adequate health care and sanitation, and economic opportunities. This position paper reviews the complex issues of global food insecurity and discusses long-term solutions for achieving world food security. Achieving the end of world hunger has been and is now within our grasp. There is sufficient food to feed everyone, and solutions can be realized now that will benefit all of humanity. As noted in the paper, most people who examine the costs of ending versus not ending world hunger are bewildered by the question of why humanity did not solve the problem a long time ago. The Association supports programs and encourages practices that combat hunger and malnutrition, produce food security, promote self-sufficiency, respect local cultures, and are environmentally and economically sustainable. The ADA recognizes that decisions and actions that dietetics professionals make as practitioners and consumers can help reduce the extent of poverty and hunger both here and abroad. This paper provides information, resources, and strategies to assist dietetics professionals in improving the public's understanding of key issues, becoming advocates of the poor, and influencing the political will to end world hunger.

Bacteriophages against Streptococcus thermophilus are a growing problem in the Italian cheese industry. One possible control method involves replacing S. thermophilus in mozzarella starter blends with lactic acid bacteria from a different genus or species. In this study, we evaluated lactose-positive pediococci for this application. Because we could not identify any commercially available pediococci with fast acid-producing ability in milk, we transformed Pediococcus pentosaceus ATCC 25744, P. pentosaceus ATCC 25745, and Pediococcus acidilactici ATCC 12697 by electroporation with pPN-1, a 35-kb Lactococcus lactis lactose plasmid. Transformants of P. pentosaceus ATCC 25745 and P. acidilactici ATCC 12697 were then used to examine lactose-positive pediococci for properties related to milk fermentation. Both transformants rapidly produced acid and efficiently retained pPN-1 in lactose broth, and neither bacterium was attacked by bacteriophages in whey collected from commercial cheese facilities. Paired starter combinations of Pediococcus spp. and Lactobacillus helveticus LH100 exhibited synergistic pH reduction in milk, and small-scale cheese trials showed that these cultures could be used to manufacture part-skim mozzarella cheese. Results demonstrate that lactose-positive pediococci have potential as replacement cocci for S. thermophilus in Italian cheese starter blends and may facilitate development of new strain rotation schemes to combat S. thermophilus bacteriophage problems in mozzarella cheese plants.

Combat experience and problem drinking in veterans: Exploring the roles of PTSD, coping motives, and perceived stigma.

PubMed

Miller, Stephen M; Pedersen, Eric R; Marshall, Grant N

2017-03-01

The current investigation sought to illustrate the etiology of adverse alcohol consequences in young adult veterans using a path analytic framework. A total of 312 veterans aged 19-34 were enrolled in a larger intervention study on alcohol use. At baseline, participants completed measures of combat severity, PTSD symptom severity, and drinking motives to cope. At one month follow-up, participants completed measures of perceived stigma of behavioral health treatment seeking and past 30-day alcohol consequences. After entering the covariates of age, gender, race/ethnicity, and past year behavioral health treatment utilization, a path analytic model demonstrated a good fit to the data predicting alcohol consequences in this population. Further, a separate exploratory analysis confirmed that both drinking motives to cope and perceived stigma of behavioral health treatment seeking mediated the link between PTSD symptom severity and alcohol consequences. The current model expands upon prior research showing the relationship between combat severity and alcohol use behavior in young adult veterans. Results support the notion that veterans with PTSD symptoms may drink to cope and that perceived stigma surrounding help seeking may further contribute to alcohol related problems.

Epigenetic alterations of the BDNF gene in combat-related post-traumatic stress disorder.

PubMed

Kim, T Y; Kim, S J; Chung, H G; Choi, J H; Kim, S H; Kang, J I

2017-02-01

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

Resting-state functional connectivity in combat veterans suffering from impulsive aggression

PubMed Central

Heesink, Lieke; van Honk, Jack; Geuze, Elbert

2017-01-01

Abstract Impulsive aggression is common among military personnel after deployment and may arise because of impaired top-down regulation of the amygdala by prefrontal regions. This study sought to further explore this hypothesis via resting-state functional connectivity analyses in impulsively aggressive combat veterans. Male combat veterans with (n = 28) and without (n = 30) impulsive aggression problems underwent resting-state functional magnetic resonance imaging. Functional connectivity analyses were conducted with the following seed-regions: basolateral amygdala (BLA), centromedial amygdala, anterior cingulate cortex (ACC), and anterior insular cortex (AIC). Regions-of-interest analyses focused on the orbitofrontal cortex and periaqueductal gray, and yielded no significant results. In exploratory cluster analyses, we observed reduced functional connectivity between the (bilateral) BLA and left dorsolateral prefrontal cortex in the impulsive aggression group, relative to combat controls. This finding indicates that combat-related impulsive aggression may be marked by weakened functional connectivity between the amygdala and prefrontal regions, already in the absence of explicit emotional stimuli. Group differences in functional connectivity were also observed between the (bilateral) ACC and left cuneus, which may be related to heightened vigilance to potentially threatening visual cues, as well as between the left AIC and right temporal pole, possibly related to negative memory association in impulsive aggression.

Combat-related blast-induced neurotrauma: a public health problem?

PubMed

Jett, Shirley

2010-01-01

The purpose of this article is to raise nurses' awareness of the significance and potential public health impact of combat-related blast-induced neurotrauma (BINT) in U.S. troops returning from Afghanistan and Iraq. A comprehensive review of the current literature on BINT was completed by the author, based primarily on combat-related blast exposure in the military population. She found that it is necessary to theorize about potential etiologies for mild traumatic brain injury in the military population since the literature suggests that neurological and psychological trauma resulting from military duty may be linked to exposure to blasts. Identification of potential risk factors for BINT in the military population provides direction for scientific inquiry into this emerging phenomenon. Gaps in current knowledge and its health implications for future scientific study in nursing are presented. © 2010 Wiley Periodicals, Inc.

Aggressive and violent behavior among military personnel deployed to Iraq and Afghanistan: prevalence and link with deployment and combat exposure.

PubMed

MacManus, Deirdre; Rona, Roberto; Dickson, Hannah; Somaini, Greta; Fear, Nicola; Wessely, Simon

2015-01-01

A systematic review and meta-analyses were conducted on studies of the prevalence of aggressive and violent behavior, as well as of violent offenses and convictions, among military personnel following deployment to Iraq and/or Afghanistan; the relationship with deployment and combat exposure; and the role that mental health problems, such as post-traumatic stress disorder (PTSD), have on the pathway between deployment and combat to violence. Seventeen studies published between January 1, 2001, and February 12, 2014, in the United States and the United Kingdom met the inclusion criteria. Despite methodological differences across studies, aggressive behavior was found to be prevalent among serving and formerly serving personnel, with pooled estimates of 10% (95% confidence interval (CI): 1, 20) for physical assault and 29% (95% CI: 25, 36) for all types of physical aggression in the last month, and worthy of further exploration. In both countries, rates were increased among combat-exposed, formerly serving personnel. The majority of studies suggested a small-to-moderate association between combat exposure and postdeployment physical aggression and violence, with a pooled estimate of the weighted odds ratio = 3.24 (95% CI: 2.75, 3.82), with several studies finding that violence increased with intensity and frequency of exposure to combat traumas. The review's findings support the mediating role of PTSD between combat and postdeployment violence and the importance of alcohol, especially if comorbid with PTSD. © The Author 2015.

Improving global health governance to combat counterfeit medicines: a proposal for a UNODC-WHO-Interpol trilateral mechanism.

PubMed

Mackey, Tim K; Liang, Bryan A

2013-10-31

Perhaps no greater challenge exists for public health, patient safety, and shared global health security, than fake/falsified/fraudulent, poor quality unregulated drugs, also commonly known as "counterfeit medicines", now endemic in the global drug supply chain. Counterfeit medicines are prevalent everywhere, from traditional healthcare settings to unregulated sectors, including the Internet. These dangerous medicines are expanding in both therapeutic and geographic scope, threatening patient lives, leading to antimicrobial resistance, and profiting criminal actors. Despite clear global public health threats, surveillance for counterfeit medicines remains extremely limited, with available data pointing to an increasing global criminal trade that has yet to be addressed appropriately. Efforts by a variety of public and private sector entities, national governments, and international organizations have made inroads in combating this illicit trade, but are stymied by ineffectual governance and divergent interests. Specifically, recent efforts by the World Health Organization, the primary international public health agency, have failed to adequately incorporate the broad array of stakeholders necessary to combat the problem. This has left the task of combating counterfeit medicines to other organizations such as UN Office of Drugs and Crime and Interpol in order to fill this policy gap. To address the current failure of the international community to mobilize against the worldwide counterfeit medicines threat, we recommend the establishment of an enhanced global health governance trilateral mechanism between WHO, UNODC, and Interpol to leverage the respective strengths and resources of these organizations. This would allow these critical organizations, already engaged in the fight against counterfeit medicines, to focus on and coordinate their respective domains of transnational crime prevention, public health, and law enforcement field operations. Specifically, by forming a global partnership that focuses on combating the transnational criminal and patient safety elements of this pre-eminent global health problem, there can be progress against counterfeit drugs and their purveyors.

2011-08-01

Trauma-associated injuries of the thorax and abdomen account for the majority of combat trauma-associated deaths, and infectious complications are common in those who survive the initial injury. This review focuses on the initial surgical and medical management of torso injuries intended to diminish the occurrence of infection. The evidence for recommendations is drawn from published military and civilian data in case reports, clinical trials, meta-analyses, and previously published guidelines, in the interval since publication of the 2008 guidelines. The emphasis of these recommendations is on actions that can be taken in the forward-deployed setting within hours to days of injury. This evidence-based medicine review was produced to support the Guidelines for the Prevention of Infections Associated With Combat-Related Injuries: 2011 Update contained in this supplement of Journal of Trauma.

Etiology of depression comorbidity in combat-related PTSD: a review of the literature.

PubMed

Stander, Valerie A; Thomsen, Cynthia J; Highfill-McRoy, Robyn M

2014-03-01

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

Mental health care use by soldiers conducting counterinsurgency operations.

Applewhite, Larry; Keller, Nathan; Borah, Adam

2012-05-01

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

A Systematic Review of Dropout From Psychotherapy for Posttraumatic Stress Disorder Among Iraq and Afghanistan Combat Veterans.

2015-10-01

A significant number of veterans of the conflicts in Iraq and Afghanistan have posttraumatic stress disorder (PTSD), yet underutilization of mental health treatment remains a significant problem. The purpose of this review was to summarize rates of dropout from outpatient, psychosocial PTSD interventions provided to U.S. Operation Iraqi Freedom (OIF), Operation Enduring Freedom (OEF), and Operation New Dawn (OND) veterans with combat-related PTSD. There were 788 articles that were identified which yielded 20 studies involving 1,191 individuals eligible for the review. The dropout rates in individual studies ranged from 5.0% to 78.2%, and the overall pooled dropout rate was 36%, 95% CI [26.20, 43.90]. The dropout rate differed marginally by study type (routine clinical care settings had higher dropout rates than clinical trials) and treatment format (group treatment had higher dropout rates than individual treatment), but not by whether comorbid substance dependence was excluded, by treatment modality (telemedicine vs. in-person treatment), or treatment type (exposure therapy vs. nonexposure therapy). Dropout is a critical aspect of the problem of underutilization of care among OEF/OIF/OND veterans with combat-related PTSD. Innovative strategies to enhance treatment retention are needed.

Combating desertification in Iran over the last 50 years: an overview of changing approaches.

PubMed

Amiraslani, Farshad; Dragovich, Deirdre

2011-01-01

Desertification in Iran was recognized between the 1930s and 1960s. This paper traces Iran's attempts to reclaim desertified areas, evaluates the anti-desertification approaches adopted, and identifies continuing challenges. Iran has areas vulnerable to desertification due to extensive areas of drylands and increasing population pressure on land and water resources. Over-grazing of rangelands is a particular problem. Initially desertification was combated mainly at the local level and involved dune stabilization measures, especially the use of oil mulch, re-vegetation and windbreaks. Insufficient technical planning in the early years has led to changed approaches to plant densities and species diversity in plantations, and increased on-going management of existing plantations. Since the late 1980s forage and crop production has increased in areas where runoff control techniques are practiced. The social and economic aspects of anti-desertification programs have assisted in poverty reduction by providing off-season employment in rural areas. In 2004 a national plan to combat desertification was ratified and this placed an emphasis on community participation. Continuing challenges include managing existing desertified areas as well as taking into account potential future problems associated with rapidly depleting groundwater supplies and a predicted reduction in the plant growth period accompanying climate change.

2012-01-01

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

2016-08-01

Identifying Department of Defense (DoD) occupations affected by injuries to the head and sensory systems. We explored the Defense Medical Epidemiology Database to identify occupations with the highest incidence of injured personnel, then ranked how frequently they occurred in a top 10 list for each of four injury categories (head/brain, visual, auditory, vestibular) encompassing 25 injury codes. Across all four categories, the most affected occupations were identified, among which we chose three Army combat-related military occupational specialties (MOSs) for detailed study. We identified skills needed to perform these MOSs and explored whether MOS-critical deficits could be expected following the injuries. Some DoD occupations are more likely to suffer from these injuries, including Infantry, Combat Operations Control, Artillery/Gunnery, Motor Vehicle Operator, Combat Engineering, and Armor/Amphibious. Within these DoD occupations, we explored three Army combatant MOSs: Infantry (11B), Cavalry Scout (19D), and Artillery (13B), confirming that these jobs are likely to be disrupted by injuries within the four categories. Head and sensory injuries disproportionately affect certain military occupations. Relatively few injuries disrupt combat-related abilities that are job critical (e.g., firearms operation) and job specific (e.g., Artillery gunnery problems); these should be the focus of efforts to improve rehabilitation and RTD outcomes.

Behavioral and emotional adjustment problems were examined in children (aged 6 –12) of an active duty Army or Marine Corps parent currently deployed (CD) or recently returned (RR) from Afghanistan or Iraq. METHOD Children (N=272) and their at-home civilian (AHC) (N=163) and/or recently returned active duty (AD) parent (N=65) were interviewed. Child adjustment outcomes were examined in relation to parental psychological distress and months of combat deployment (of the AD) using mixed effects linear models. RESULTS Parental distress (AHC and AD) and cumulative length of parental combat-related deployments during the child’s lifetime independently predicted increased child depression and externalizing symptoms. Although behavioral adjustment and depression levels were comparable to community norms, anxiety was significantly elevated in children in both deployment groups. In contrast, AHC parental distress was greater in those with a CD (vs. RR) spouse. CONCLUSIONS Findings indicate parental combat deployment has a cumulative effect on children which remains even after the deployed parent returns home, and is predicted by psychological distress of both the AD and AHC parent. Such data may be informative for screening, prevention and intervention strategies. PMID:20410724

Prescription drug abuse: problem, policies, and implications.

PubMed

Phillips, Janice

2013-01-01

This article provides an overview on prescription drug abuse and highlights a number of related legislative bills introduced during the 112th Congress in response to this growing epidemic. Prescription drug abuse has emerged as the nation's fastest growing drug problem. Although prescription drugs have been used effectively and appropriately for decades, deaths from prescription pain medicine in particular have reached epidemic proportions. Bills related to prescription drug abuse introduced during the 112th Congress focus on strengthening provider and consumer education, tracking and monitoring prescription drug abuse, improving data collection on drug overdose fatalities, combating fraud and abuse in Medicare and Medicaid programs, reclassifying drugs to make them more difficult to prescribe and obtain, and enforcing stricter penalties for individuals who operate scam pain clinics and sell pain pills illegitimately. This article underscores the importance of a multifaceted approach to combating prescription drug abuse and concludes with implications for nursing. Copyright © 2013. Published by Mosby, Inc.

Studies aiming to identify if war veterans are at higher risk of suicide have often produced inconsistent results; this could be due to the complexity of comparisons and different methodological approaches. It should be noted that this contingent has many risk factors, such as stressful exposures, wounds, brain trauma and pain syndrome. Most recent observations confirm that veterans are really more likely to die of suicide as compared to the general population; they are also more likely to experience suicidal ideation and suffer from mental health problems. Suicides are more frequent in those who develop PTSD, depression and comorbid states due to war exposure. Combat stress and its' frequency may be an important factor leading to suicide within the frame of the stress-vulnerability model. According to this model, the effects of stress may interact with social factors, interpersonal relations and psychological variables producing suicidal tendencies. Modern understanding of stress-vulnerability mechanisms based on genetic predispositions, early life development, level of exposure to stress and stress-reactivity together with interpersonal aspects may help to build more effective suicide prevention programs based on universal/selective/indicated prevention principles.

2014-01-01

With the advance of military technology, the number of unmanned combat aerial vehicles (UCAVs) has rapidly increased. However, it has been reported that the accident rate of UCAVs is much higher than that of manned combat aerial vehicles. One of the main reasons for the high accident rate of UCAVs is the hypovigilance problem which refers to the decrease in vigilance levels of UCAV operators while maneuvering. In this paper, we propose hypovigilance detection models for UCAV operators based on EEG signal to minimize the number of occurrences of hypovigilance. To enable detection, we have applied hidden Markov models (HMMs), two of which are used to indicate the operators' dual states, normal vigilance and hypovigilance, and, for each operator, the HMMs are trained as a detection model. To evaluate the efficacy and effectiveness of the proposed models, we conducted two experiments on the real-world data obtained by using EEG-signal acquisition devices, and they yielded satisfactory results. By utilizing the proposed detection models, the problem of hypovigilance of UCAV operators and the problem of high accident rate of UCAVs can be addressed. PMID:24963338

Military service members (SMs) and veterans who sustain mild traumatic brain injuries (mTBI) during combat deployments often have co-morbid conditions but are reluctant to seek out therapy in medical or mental health settings. Efficacious methods of intervention that are patient-centered and adaptable to a mobile and often difficult-to-reach population would be useful in improving quality of life. This article describes a new protocol developed as part of a randomized clinical trial of a telephone-mediated program for SMs with mTBI. The 12-session program combines problem solving training (PST) with embedded modules targeting depression, anxiety, insomnia, and headache. The rationale and development of this behavioral intervention for implementation with persons with multiple co-morbidities is described along with the proposed analysis of results. In particular, we provide details regarding the creation of a treatment that is manualized yet flexible enough to address a wide variety of problems and symptoms within a standard framework. The methods involved in enrolling and retaining an often hard-to-study population are also highlighted. Copyright © 2014 Elsevier Inc. All rights reserved.

2011-05-01

The relationship between war exposure and post-traumatic stress disorder (PTSD) has been largely investigated but the impact of the combat experience on physical health has only recently merited attention. The authors investigated the relationship between war exposure and psychological and physical health among 350 Portuguese colonial war veterans. The role of current PTSD symptoms as a mediator of these relationships was also investigated. The results showed that 39% of the veterans met criteria for current PTSD diagnosis and psychological distress was present in half of the sample. Pain, fatigue, and sleep problems were the most reported physical symptoms and mental health and gastro-intestinal problems, the most reported illnesses. Combat exposure variables were significant predictors of current health. The results indicated that veterans with higher exposure to war trauma maintained higher current levels of psychological distress and presented more physical health problems and physical symptoms than those less exposed. Mediation analyses showed that current PTSD was a full mediator of the relationship between war exposure and physical health outcomes.

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

This study evaluated the relationship between resilience and psychological functioning in military veterans deployed to a region of military conflict in support of Operation Enduring Freedom or Operation Iraqi Freedom. 497 military veterans completed a structured psychiatric interview and questionnaires measuring psychological symptoms, resiliency, and trauma exposure. The study had 2 primary aims: (1) to examine whether the association between trauma exposure and PTSD was moderated by resilience and (2) to examine whether resilience was uniquely associated with functional outcomes after accounting for PTSD. Measures included the Structured Clinical Interview for DSM-IV-TR Axis I Disorders (for PTSD diagnosis), the Connor-Davidson Resilience Scale, and the Traumatic Life Events Questionnaire. Data were collected between June 2005 and February 2009. Evaluating the association of resilience and trauma exposure with PTSD revealed main effects for combat exposure, lifetime trauma exposure, and resilience. Additionally, there was a significant (P < .05) interaction between combat exposure and resilience such that higher levels of resilience were particularly protective among individuals with high combat exposure. After controlling for age, gender, minority status, trauma exposure, and PTSD diagnosis, resilience was uniquely associated with decreased suicidality, reduced alcohol problems, lower depressive symptom severity, and fewer current health complaints and lifetime and past-year medical problems. These results suggest that resilience is a construct that may play a unique role in the occurrence of PTSD and severity of other functional correlates among deployed veterans. Future studies in this area would benefit from a prospective design, the evaluation of other possible protective processes (e.g., social support), and specific examination of particular aspects of resilience and how resilience may be increased.

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

Combat-related posttraumatic stress disorder (PTSD) can be a difficult condition to treat and has been associated with serious medical and economic issues among U.S. military veterans. Distinguishing between treatment responders vs. non-responders in this population has become an important public health priority. This study was conducted to identify pre-treatment characteristics of U.S. veterans with combat-related PTSD that might contribute to favorable and unfavorable responses to high value treatments for this condition. This study focused on 805 patients who completed a VHA PTSD residential program between 2000 and 2007. These patients completed the PTSD Clinical Checklist at pre-treatment, post-treatment, and a four-month follow-up assessment. Latent growth curve analysis (LCGA) was incorporated to determine trajectories of changes in PTSD across these assessments and whether several key clinical concerns for this population were associated with their treatment responses. LCGA indicated three distinct trajectories in PTSD outcomes and identified several clinical factors that were prospectively linked with changes in veterans' posttraumatic symptomatology. When compared to a group with high PTSD symptom severity that decreased over the program but relapsed at follow-up (41%), the near half (48.8%) of the sample with an improving trajectory had less combat exposure and superior physical/mental health. However, when compared to a minority (10.2%) with relatively low symptomatology that also remained somewhat stable, patients in the improving group were younger and also reported greater combat exposure, poorer physical/mental health status, and more problems with substance abuse before the start of treatment. Findings suggest that veterans are most likely to benefit from residential treatment in an intermediate range of symptoms and risk factors, including PTSD symptom severity, history of combat exposure, and comorbid issues with physical/mental health. Addressing these factors in an integrative manner could help to optimize the effectiveness of treatments of combat-related PTSD in many cases.

Combat casualty care: the Alpha Surgical Company experience during Operation Iraqi Freedom.

Operation Iraqi Freedom was the first large-scale combat operation involving the U.S. Marine Corps since the Persian Gulf War in 1991. Data from a combat surgical company are presented. Records of all U.S. and Iraqi combat casualties admitted to the surgical company were reviewed. Fifty-three (57%) of 93 patients suffered penetrating injuries. Most wounds were produced by high-explosive munitions (mines, hand grenades, and rocket-propelled grenades), and the majority (51%) of wounds were to the extremities. The time to surgical care averaged 4.7 hours (range, 1.5-48 hours), and 98% of the patients seen at our facility survived. The time from injury to surgical care was considered long by civilian standards; however, this did not appear to affect outcomes substantially. A small percentage (5.2%) of injuries were to the torso. Hypothermia was commonly present. Because of the nature of their wounds, all patients required additional surgery after evacuation to rear area facilities. The outcomes of individual patients are not known, although it is known that only one Marine died after reaching medical care and, to date, no Marines have subsequently died of their wounds.

Integration of females in combat units poses a unique challenge for army commanders around the world. The purpose of this study is to provide a detailed up-to-date situation report regarding overuse injuries among combat female warriors in the IDF (Israeli Defense Forces) in order to enable evidence-based decision-making, prevention policy, and further research of this highly significant military public health issue. A cross-sectional descriptive study was conducted including 2,519 females recruited to combat duties during the year of 2013. The main data source was the IDF's computerized medical consultation records package (CPR). Descriptive statistics was performed and some results were compared with males using data from other reports and studies of the IDF. The overall injury rate was 28.3%. Of all injuries, 86% were in the ankle and calf (41%), the lower back (23%), and the knee (22%) regions. The average lost training days was 11 d for females as compared with 8 d for males. The overall rates of stress fractures and the rates of femur and femoral neck stress fractures were significantly higher among females as compared with males (11.2% vs. 2.5%, p = 0.0032, and 7.8% vs. 1.6% p = 0.00001, respectively). The overuse injury rates among females in the IDF are high and may be considered a significant military public health problem. In order to reduce the numbers of overuse injuries, which is expected to significantly increase after the IDF's policy change regarding to combat duties open for females, we recommend planning and implementation of policies and intervention programs and further research regarding to overuse injuries among female combat warriors with special focus on the calf and ankle, lower back, and knee regions and femoral stress fractures.

A Meta-Analysis of Risk Factors for Combat-Related PTSD among Military Personnel and Veterans

Post-traumatic stress disorder (PTSD), a complex and chronic disorder caused by exposure to a traumatic event, is a common psychological result of current military operations. It causes substantial distress and interferes with personal and social functioning. Consequently, identifying the risk factors that make military personnel and veterans more likely to experience PTSD is of academic, clinical, and social importance. Four electronic databases (PubMed, Embase, Web of Science, and PsycINFO) were used to search for observational studies (cross-sectional, retrospective, and cohort studies) about PTSD after deployment to combat areas. The literature search, study selection, and data extraction were conducted by two of the authors independently. Thirty-two articles were included in this study. Summary estimates were obtained using random-effects models. Subgroup analyses, sensitivity analyses, and publication bias tests were performed. The prevalence of combat-related PTSD ranged from 1.09% to 34.84%. A total of 18 significant predictors of PTSD among military personnel and veterans were found. Risk factors stemming from before the trauma include female gender, ethnic minority status, low education, non-officer ranks, army service, combat specialization, high numbers of deployments, longer cumulative length of deployments, more adverse life events, prior trauma exposure, and prior psychological problems. Various aspects of the trauma period also constituted risk factors. These include increased combat exposure, discharging a weapon, witnessing someone being wounded or killed, severe trauma, and deployment-related stressors. Lastly, lack of post-deployment support during the post-trauma period also increased the risk of PTSD. The current analysis provides evidence of risk factors for combat-related PTSD in military personnel and veterans. More research is needed to determine how these variables interact and how to best protect against susceptibility to PTSD. PMID:25793582

Antimicrobial resistance (AMR) is one of the major threats to public health around the world. Besides the intense use and misuse of antimicrobial agents as the major force behind the increase in antimicrobial resistance, the exponential increase of international travel may also substantially contribute to the emergence and spread of AMR. However, knowledge on the extent to which international travel contributes to this is still limited. The Carriage Of Multiresistant Bacteria After Travel (COMBAT) study aims to 1. determine the acquisition rate of multiresistant Enterobacteriaceae during foreign travel 2. ascertain the duration of carriage of these micro-organisms 3. determine the transmission rate within households 4. identify risk factors for acquisition, persistence of carriage and transmission of multiresistant Enterobacteriaceae. The COMBAT-study is a large-scale multicenter longitudinal cohort study among travellers (n = 2001) and their non-travelling household members (n = 215). Faecal samples are collected before and immediately after travel and 1 month after return from all participants. Follow-up faecal samples are collected 3, 6 and 12 months after return from travellers (and their non-travelling household members) who acquired multiresistant Enterobacteriaceae. Questionnaires are collected from all participants at each time-point. Faecal samples are screened phenotypically for the presence of extended-spectrum beta-lactamase (ESBL) or carbapenemase-producing Enterobacteriaceae. Positive post-travel isolates from travellers with negative pre-travel samples are genotypically analysed for ESBL and carbapenemase genes with microarray and gene sequencing. The design and scale of the COMBAT-study will enable us to provide much needed detailed insights into the risks and dynamics of introduction and spread of ESBL- and carbapenemase-producing Enterobacteriaceae by healthy travellers and the potential need and measures to monitor or manage these risks. The study is registered at clinicaltrials.gov under accession number NCT01676974.

Cancer is the most deadly disease that causes the serious health problems, physical disabilities, mortalities, and morbidities around the world. It is the second leading cause of death all over the world. Although great advancement have been made in the treatment of cancer progression, still significant deficiencies and room for improvement remain. Chemotherapy produced a number of undesired and toxic side effects. Natural therapies, such as the use of plant-derived products in the treatment of cancer, may reduce adverse and toxic side effects. However, many plants exist that have shown very promising anticancer activities in vitro and in vivo but their active anticancer principle have yet to be evaluated. Combined efforts of botanist, pharmacologist and chemists are required to find new lead anticancer constituent to fight disease. This review will help researchers in the finding of new bioactive molecules as it will focus on various plants evaluated for anticancer properties in vitro and in vivo.

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 bathingmore » 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.« less

Dermal disease can be a 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 showeringmore » or bathing for soldiers in an combat setting is complicated by the fact that soldiers in the US Army may be involved in field exercises 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. A separate but related area of interest involves evaluating whether the use of antimicrobial soaps or similar products minimize the incidence of skin infections by decreasing populations of disease-causing microorganisms on the skin. 13 refs., 2 figs., 2 tabs.« less

Cytokine production as a putative biological mechanism underlying stress sensitization in high combat exposed soldiers.

Combat stress exposed soldiers may respond to post-deployment stressful life events (SLE) with increases in symptoms of posttraumatic stress disorder (PTSD), consistent with a model of stress sensitization. Several lines of research point to sensitization as a model to describe the relations between exposure to traumatic events, subsequent SLE, and symptoms of PTSD. Based on previous findings we hypothesized that immune activation, measured as a high in vitro capacity of leukocytes to produce cytokines upon stimulation, underlies stress sensitization. We assessed mitogen-induced cytokine production at 1 month, SLE at 1 year, and PTSD symptoms from 1 month up to 2 years post-deployment in soldiers returned from deployment to Afghanistan (N=693). Exploratory structural equation modeling as well as latent growth models were applied. The data demonstrated significant three-way interaction effects of combat stress exposure, cytokine production, and post-deployment SLE on linear change in PTSD symptoms over the first 2 years following return from deployment. In soldiers reporting high combat stress exposure, both high mitogen-stimulated T-cell cytokine production and high innate cytokine production were associated with increases in PTSD symptoms in response to post-deployment SLE. In low combat stress exposed soldiers as well as those with low cytokine production, post-deployment SLE were not associated with increases in PTSD symptoms. High stimulated T-cell and innate cytokine production may contribute to stress sensitization in recently deployed, high combat stress exposed soldiers. These findings suggest that detecting and eventually normalizing immune activation may potentially complement future strategies to prevent progression of PTSD symptoms following return from deployment.

This study analyzed the outcome of a 4-month intensive inpatient program for combat-related posttraumatic stress disorder (PTSD) among Vietnam veterans. The subjects were 51 male veterans with PTSD who completed the inpatient treatment program. Comprehensive measures of PTSD and psychiatric symptoms, as well as social functioning, were assessed at admission, discharge, and 6, 12, and 18 months after discharge. The overall study group showed an increase in symptoms from admission to follow-up and a decrease in violent actions and thoughts and legal problems. Family and interpersonal relationships and overall morale were improved at discharge but then returned to pretreatment levels at 18 months. Patient evaluations also indicated that the program affected morale and interpersonal relationships but not symptoms. The chronic nature of combat-related PTSD among Vietnam veterans is evident. The study raises the possibility that long-term intensive inpatient treatment is not effective, and other forms of treatment should be considered after rigorous study of such variables as length of stay, trauma versus rehabilitation focus, and patient characteristics.

Environmental factors, immune changes and respiratory diseases in troops during military activities.

Korzeniewski, Krzysztof; Nitsch-Osuch, Aneta; Chciałowski, Andrzej; Korsak, Jolanta

2013-06-01

Combat operations in contemporary theaters of war, as well as combat training, are carried out in all parts of the world, typically in a harsh environment. Specific environmental conditions, such as heat, cold, high-altitudes, desert climates, as well as chemical and biological pollution of both the atmosphere and soil, together with over-exertion, food restrictions, sleep deprivation, and psychological stress can all result in changes in the immune system and the occurrence of associated diseases. Respiratory diseases are one of the most common health problems among military personnel participating in combat training or deployed to operations in areas characterized by difficult climatic and sanitary conditions. They are, therefore, one of the main reasons for military personnel requiring ambulant and hospital treatment. The aim of the study was to discuss the influence of environmental factors and the conditions in which active duty is performed on changes in the immune system and the occurrence of respiratory tract diseases in a military environment.

2011-08-01

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

To understand legislation combating counterfeit drugs in Hong Kong. This study consisted of two parts. In part I, counterfeit drugs–related ordinances and court cases were reviewed. In part II, indepth interviews of the stakeholders were described. Hong Kong. All Hong Kong ordinances were screened manually to identify those combating counterfeit drugs. Court cases were searched for each of the identified cases. Then, the relevant judgement justifications were analysed to identify sentencing issues. Indepth interviews with the stakeholders were conducted to understand their perceptions about such legislation. Trade Marks Ordinance, Patents Ordinance, Trade Descriptions Ordinance, and Pharmacy and Poisons Ordinance were current legislative items combating counterfeit drugs. Sentencing criteria depended on: intention to deceive, quantity of seized drugs, presence of expected therapeutic effect or toxic ingredients, previous criminal records, cooperativeness with Customs officers, honest confessions, pleas of guilty, types of drugs, and precautionary measures to prevent sale of counterfeit drugs. Stakeholders’ perceptions were explored with respect to legislation regarding the scale and significance of the counterfeit drug problem, penalties and deterrents, drug-specific legislation and authority, and inspections and enforcement. To plug the loopholes, a specific law with heavy penalties should be adopted. This could be supplemented by non-legal measures like education of judges, lawyers, and the public; publishing the names of offending pharmacies; and emphasising the role of pharmacists to the public.

The Impact of Combat Deployment on Health Care Provider Burnout in a Military Emergency Department: A Cross-Sectional Professional Quality of Life Scale V Survey Study.

2016-08-01

Compassion fatigue is a problem for many health care providers manifesting as physical, mental, and spiritual exhaustion. Our objective was to evaluate the association between prior combat deployment and compassion fatigue among military emergency medicine providers. We conducted a nonexperimental cross-sectional survey of health care providers assigned to the San Antonio Military Medical Center, Department of Emergency Medicine. We used the Professional Quality of Life Scale V survey instrument that evaluates provider burnout, secondary traumatic stress, and compassion satisfaction. Outcomes included burnout, secondary traumatic stress, and compassion satisfaction raw scores. Scores were compared between providers based on previous combat deployments using two-tailed independent sample t tests and multiple regression models. Surveys were completed by 105 respondents: 42 nurses (20 previously deployed), 30 technicians (11 previously deployed), and 33 physicians (16 previously deployed). No statistically significant differences in burnout, secondary traumatic stress, or compassion satisfaction scores were detected between previously deployed providers versus providers not previously deployed. There was no association between previous combat deployment and emergency department provider burnout, secondary traumatic stress, or compassion satisfaction scores.

2015-08-01

This White Paper summarizes the state of readiness of combat surgeons and provides action recommendations that address the problems of how to train, sustain, and retain them for future armed conflicts. As the basis for the 2014 Scudder Oration, I explored how to secure an improved partnership between military and civilian surgery, which would optimize learning platforms and embed military trauma personnel at America's academic medical universities for trauma combat casualty care (TCCC). To craft and validate these recommendations, I conducted an integrative and iterative process of literature reviews, interviews of military and civilian leaders, and a survey of military-affiliated surgeons. The recommended action points advance the training of combat surgeons and their trauma teams by creating an expanded network of TCCC training sites and sourcing the cadre of combat-seasoned surgeons currently populating our civilian and military teaching hospitals and universities. The recommendation for the establishment of a TCCC readiness center or command within the Medical Health System of the Department of Defense includes a military and civilian advisory board, with the reformation of a think tank of content experts to address high-level solutions for military medicine, readiness, and TCCC.

Ting, S. L.; Ip, W. H.

Due to the globalisation of counterfeiting activities, the penetration of fake products in open market is growing. So far, the technologies to combat counterfeiting are mostly applied to high-value products (e.g. premium wine and branded handbags); however, in the medium- and low-value products' perspective, there is no secure way for consumers to identify whether the purchased items are genuine or not. To address the counterfeiting problems effectively, a platform for identifying authenticated products and promoting anti-counterfeit activities is very important. The aim of this paper is to design and develop an anti-counterfeit platform which includes two functions: providing customers a secure network to ascertain the genuineness of their purchased product and increasing public awareness of the current counterfeit problems and updated anti-counterfeit solutions. By combining these two functions, it enables public to fight against fake and beware of counterfeit. Results of adopting portal technology in anti-counterfeiting show high accuracy in product checking and improved creditability. This reveals that the applicability and advantage of the proposed methodology are satisfactory.

Enhancing self-efficacy improves episodic future thinking and social-decision making in combat veterans with posttraumatic stress disorder.

Posttraumatic Stress Disorder (PTSD) is associated with maladaptive changes in self-identity, including impoverished perceived self-efficacy. This study examined if enhancing perceptions of self-efficacy in combat veterans with and without symptoms of PTSD promotes cognitive strategies associated with positive mental health outcomes. Prior to completing a future thinking and social problem-solving task, sixty-two OEF/OIF veterans with and without symptoms of PTSD were randomized to either a high self-efficacy (HSE) induction in which they were asked to recall three autobiographical memories demonstrating self-efficacy or a control condition in which they recalled any three autobiographical events. An interaction between HSE and PTSD revealed that individuals with symptoms of PTSD in the HSE condition generated future events with more self-efficacious statements than those with PTSD in the control condition, whereas those without PTSD did not differ in self-efficacy content across the conditions. In addition, individuals in the HSE condition exhibited better social problem solving than those in the control condition. Increasing perceptions of self-efficacy may promote future thinking and problem solving in ways that are relevant to overcoming trauma and adversity. Copyright © 2016 Elsevier Ireland Ltd.

Disease mongering.

Shankar, P R; Subish, P

2007-04-01

Convincing healthy people that they are sick and require medicines can enormously expand the market. Disease mongering can turn ordinary ailments like baldness into medical problems, consider risk factors such as hypertension and osteoporosis as diseases and frame prevalence estimates to increase potential markets. In Asia, conditions like erectile dysfunction, male pattern baldness, attention deficit hyperactivity disorder and irritable bowel syndrome, and the drugs to treat them, are widely promoted. Fairness creams and traditional medicines are also widely used. The cost of disease mongering to the individual and the community is expected to be high. Some authors have argued that medicalisation of illnesses may not be a problem and the real problem may be the lack of medicines. Doctors will play a key role in combating disease mongering. Disentanglement from the pharmaceutical industry and development of a capacity for critical analysis are required. Educating patients and empowering them to make decisions are important. Several initiatives have been undertaken to combat disease mongering. Initiatives at the level of the patient and the physician are especially important. Studies on the extent and knowledge of disease mongering among doctors and medical students, and their economic and social consequences are urgently required.

Paid counter-advertising: proven strategy to combat tobacco use and promotion.

PubMed

Blum, A

1994-01-01

This article discusses the effectiveness of paid counter-advertising in combating tobacco use and promotion, the impact of the Fairness Doctrine, which mandated anticigarette television advertisements in the late 1960s, and reasons why the media today are reluctant to run antismoking advertisements. Although counter-advertisements can work very well, they should be image-based, rather than fact-based. Currently, tobacco companies promote a positive image of cigarette smoking and brand awareness. Most antismoking ads, however, tend to focus on the tobacco itself and its adverse effects on the smoker, rather than combating the images the cigarette ads promote. Urging counter-advertising to focus on the product, rather than to try to produce guilt in smokers, this article provides examples of paid counter-advertising strategies employed by Doctors Ought to Care to illustrate an image-based approach. Overall, the antismoking movement must guard against complacency and measure its success according to tobacco companies' declining revenues, rather than the number of public service advertisements in the media.

The prediction of the total drag experienced by an advancing ship is a complicated problem which requires a thorough understanding of the hydrodynamic forces acting on the hull, the physical processes from which these forces arise and their mutual interaction. A general numerical method to predict the hydrodynamic performance of a twin-propeller combatant ship hull is presented in the paper. For practical reasons, the technique couples a body forces method and a RANS-based finite volume solver to account for the interactions between the hull and the appendages mounted on it: propellers, rudders, shaft lines, bossings and brackets. The chimera approach has been found the most versatile way for grid generation of hull and appendages.

The diversity of anti-microbial secondary metabolites produced by fungal endophytes: an interdisciplinary perspective.

2013-01-01

Endophytes are microbes that inhabit host plants without causing disease and are reported to be reservoirs of metabolites that combat microbes and other pathogens. Here we review diverse classes of secondary metabolites, focusing on anti-microbial compounds, synthesized by fungal endophytes including terpenoids, alkaloids, phenylpropanoids, aliphatic compounds, polyketides, and peptides from the interdisciplinary perspectives of biochemistry, genetics, fungal biology, host plant biology, human and plant pathology. Several trends were apparent. First, host plants are often investigated for endophytes when there is prior indigenous knowledge concerning human medicinal uses (e.g., Chinese herbs). However, within their native ecosystems, and where investigated, endophytes were shown to produce compounds that target pathogens of the host plant. In a few examples, both fungal endophytes and their hosts were reported to produce the same compounds. Terpenoids and polyketides are the most purified anti-microbial secondary metabolites from endophytes, while flavonoids and lignans are rare. Examples are provided where fungal genes encoding anti-microbial compounds are clustered on chromosomes. As different genera of fungi can produce the same metabolite, genetic clustering may facilitate sharing of anti-microbial secondary metabolites between fungi. We discuss gaps in the literature and how more interdisciplinary research may lead to new opportunities to develop bio-based commercial products to combat global crop and human pathogens.

Probiotic therapy: immunomodulating approach toward urinary tract infection.

PubMed

Amdekar, Sarika; Singh, Vinod; Singh, Desh Deepak

2011-11-01

Urinary tract infection (UTI) is an extremely common health problem, with an unpredictable history. Members of enterobacteriaceae family such as Escherichia coli, which are normal inhabitants of human intestines, account for the majority of these uncomplicated infections. Rarely, UTI can result from virus or fungus. There is a close correlation between loss of the normal genital microbiota, particularly Lactobacillus species, and an increased incidence of genital and bladder infections. Although antimicrobial agents are generally effective in eradicating these infections, there is a high incidence of recurrence. Use of Lactobacillus species to combat UTI is now giving modern concept of modern genitourinary vaccine with the facts that it not only maintains low pH of the genital area, produces hydrogen peroxide and hinders the growth of E. coli but also activates Toll-like receptor-2 (TLR2), which produces interleukin-10 (IL-10) and myeloid differentiation factor 88 (MyD88). E. coli activates TLR4, which is responsible for the activation of IL-12, extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK). This process downregulates inflammatory reactions caused due to pathogens. Current review covers the probiotics-based TLR therapy and shed some knowledge for the use of Lactobacillus species as probiotics.

A growing body of literature has demonstrated the association of combat in Iraq and Afghanistan with postdeployment mental health problems, particularly posttraumatic stress disorder (PTSD) and depression. However, studies have shown varying prevalence rates of these disorders based on different case definitions and have not assessed functional impairment, alcohol misuse, or aggressive behavior as comorbid factors occurring with PTSD and depression. To (1) examine the prevalence rates of depression and PTSD using several case definitions including functional impairment, (2) determine the comorbidity of alcohol misuse or aggressive behaviors with depression or PTSD, and (3) compare rates between Active Component and National Guard soldiers at the 3- and 12-month time points following their deployment to Iraq. Population-based, cross-sectional study. United States Army posts and National Guard armories. A total of 18 305 US Army soldiers from 4 Active Component and 2 National Guard infantry brigade combat teams. Between 2004 and 2007, anonymous mental health surveys were collected at 3 and 12 months following deployment. Current PTSD, depression, functional impairment, alcohol misuse, and aggressive behavior. Prevalence rates for PTSD or depression with serious functional impairment ranged between 8.5% and 14.0%, with some impairment between 23.2% and 31.1%. Alcohol misuse or aggressive behavior comorbidity was present in approximately half of the cases. Rates remained stable for the Active Component soldiers but increased across all case definitions from the 3- to 12-month time point for National Guard soldiers. The prevalence rates of PTSD and depression after returning from combat ranged from 9% to 31% depending on the level of functional impairment reported. The high comorbidity with alcohol misuse and aggression highlights the need for comprehensive postdeployment screening. Persistent or increased prevalence rates at 12 months compared with 3 months postdeployment illustrate the persistent effects of war zone service and provide important data to guide postdeployment care.

Under evolutionary pressure from chemotherapy, cancer cells develop resistance characteristics such as a low redox state, which eventually leads to treatment failures. An attractive option for combatting resistance is producing a high concentration of produced free radicals in situ. Here, we report the production and use of dispersible hollow carbon nanospheres (HCSs) as a novel platform for delivering the drug doxorubicine (DOX) and generating additional cellular reactive oxygen species using near-infrared laser irradiation. These irradiated HCSs catalyzed sufficiently persistent free radicals to produce a large number of heat shock factor-1 protein homotrimers, thereby suppressing the activation and function of resistance-related genes. Laser irradiation also promoted the release of DOX from lysosomal DOX@HCSs into the cytoplasm so that it could enter cell nuclei. As a result, DOX@HCSs reduced the resistance of human breast cancer cells (MCF-7/ADR) to DOX through the synergy among photothermal effects, increased generation of free radicals, and chemotherapy with the aid of laser irradiation. HCSs can provide a unique and versatile platform for combatting chemotherapy-resistant cancer cells. These findings provide new clinical strategies and insights for the treatment of resistant cancers.

Model Checking - My 27-Year Quest to Overcome the State Explosion Problem

NASA Technical Reports Server (NTRS)

Clarke, Ed

2009-01-01

Model Checking is an automatic verification technique for state-transition systems that are finite=state or that have finite-state abstractions. In the early 1980 s in a series of joint papers with my graduate students E.A. Emerson and A.P. Sistla, we proposed that Model Checking could be used for verifying concurrent systems and gave algorithms for this purpose. At roughly the same time, Joseph Sifakis and his student J.P. Queille at the University of Grenoble independently developed a similar technique. Model Checking has been used successfully to reason about computer hardware and communication protocols and is beginning to be used for verifying computer software. Specifications are written in temporal logic, which is particularly valuable for expressing concurrency properties. An intelligent, exhaustive search is used to determine if the specification is true or not. If the specification is not true, the Model Checker will produce a counterexample execution trace that shows why the specification does not hold. This feature is extremely useful for finding obscure errors in complex systems. The main disadvantage of Model Checking is the state-explosion problem, which can occur if the system under verification has many processes or complex data structures. Although the state-explosion problem is inevitable in worst case, over the past 27 years considerable progress has been made on the problem for certain classes of state-transition systems that occur often in practice. In this talk, I will describe what Model Checking is, how it works, and the main techniques that have been developed for combating the state explosion problem.

Stigma, barriers to care, and use of mental health services among active duty and National Guard soldiers after combat.

PubMed

Kim, Paul Y; Thomas, Jeffrey L; Wilk, Joshua E; Castro, Carl A; Hoge, Charles W

2010-06-01

This study examined rates of utilization of mental health care among active duty and National Guard soldiers with mental health problems three and 12 months after they returned from combat in Iraq. Stigma and barriers to care were also reported for each component (active duty and National Guard). Cross-sectional, anonymous surveys were administered to 10,386 soldiers across both time points and components. Mean scores from 11 items measuring stigma and barriers to care were computed. Service utilization was assessed by asking soldiers whether they had received services for a mental health problem from a mental health professional, a medical doctor, or the Department of Veterans Affairs in the past month. Risk of mental problems was measured using the Patient Health Questionnaire, the PTSD Checklist, and items asking about aggressive behaviors and "stress, emotional, alcohol, or family" problems within the past month. A higher proportion of active duty soldiers than National Guard soldiers reported at least one type of mental health problem at both three months (45% versus 33%) and 12 months (44% versus 35%) postdeployment. Among soldiers with mental health problems, National Guard soldiers reported significantly higher rates of mental health care utilization 12 months after deployment, compared with active duty soldiers (27% versus 13%). Mean stigma scores were higher among active duty soldiers than among National Guard soldiers. Active duty soldiers with a mental health problem had significantly lower rates of service utilization than National Guard soldiers and significantly higher endorsements of stigma. Current and future efforts to improve care for veterans should work toward reducing the stigma of receiving mental health care.

Health and reproductive outcomes among American legionnaires in relation to combat and herbicide exposure in Vietnam

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

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

1988-12-01

History of diagnosed illnesses, medical symptoms, and reproductive outcomes and their relation to combat intensity and herbicide exposure were studied, via a mailed questionnaire, among 6,810 American Legionnaires who served during the Vietnam War (42% in Southeast Asia, 58% elsewhere). Heart disease, venereal disease, and benign fatty tumors were reported significantly more often by Vietnam veterans than by controls. Combat intensity was significantly dosage-related to history of high blood pressure, ulcers, arthritis and rheumatism, genito-urinary problems, nervous system disease, major injury, hepatitis, and benign fatty tumors. Agent Orange exposure was significantly dosage-related to history of benign fatty tumors, adult acne,more » skin rash with blisters, and increased sensitivity of eyes to light. Rates of the latter two conditions and of change in skin color were especially elevated in men whose military occupations involved direct handling of herbicides. Neither combat nor Agent Orange exposure was associated with difficulty in conception, time to conception of first child, or to birthweight or sex ratio of offspring, but maternal smoking was strongly related to reduced birthweight. The percentage of spouses' pregnancies which resulted in miscarriages was significantly higher for Vietnam veterans than controls. Logistic regression analysis showed that Agent Orange exposure and maternal smoking were both independently and significantly associated with miscarriage rates in a dose-related manner.« less

2016-06-01

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

From badge of pride to cause of stigma: combatting mal del pinto in Mexico.

PubMed

Carrillo, Ana María

2013-03-01

Mal del pinto is a dermatological disease characterized by discoloured patches of skin on the face and body. It has been present in what is now the territory of Mexico from before the Spanish conquest up to recent times. Though early concerns for mal del pinto as a public health problem can be traced back to the late 19th century, no campaign to combat the disease was undertaken until the second half of the 20th. Thanks to the effectiveness of treatment with penicillin, the fight against this illness--which was once assumed as a symbol of pride--enjoyed a broader acceptance among the population that other health campaigns.

The Carriage Of Multiresistant Bacteria After Travel (COMBAT) prospective cohort study: methodology and design

PubMed Central

2014-01-01

Background Antimicrobial resistance (AMR) is one of the major threats to public health around the world. Besides the intense use and misuse of antimicrobial agents as the major force behind the increase in antimicrobial resistance, the exponential increase of international travel may also substantially contribute to the emergence and spread of AMR. However, knowledge on the extent to which international travel contributes to this is still limited. The Carriage Of Multiresistant Bacteria After Travel (COMBAT) study aims to 1. determine the acquisition rate of multiresistant Enterobacteriaceae during foreign travel 2. ascertain the duration of carriage of these micro-organisms 3. determine the transmission rate within households 4. identify risk factors for acquisition, persistence of carriage and transmission of multiresistant Enterobacteriaceae. Methods/design The COMBAT-study is a large-scale multicenter longitudinal cohort study among travellers (n = 2001) and their non-travelling household members (n = 215). Faecal samples are collected before and immediately after travel and 1 month after return from all participants. Follow-up faecal samples are collected 3, 6 and 12 months after return from travellers (and their non-travelling household members) who acquired multiresistant Enterobacteriaceae. Questionnaires are collected from all participants at each time-point. Faecal samples are screened phenotypically for the presence of extended-spectrum beta-lactamase (ESBL) or carbapenemase-producing Enterobacteriaceae. Positive post-travel isolates from travellers with negative pre-travel samples are genotypically analysed for ESBL and carbapenemase genes with microarray and gene sequencing. Discussion The design and scale of the COMBAT-study will enable us to provide much needed detailed insights into the risks and dynamics of introduction and spread of ESBL- and carbapenemase-producing Enterobacteriaceae by healthy travellers and the potential need and measures to monitor or manage these risks. Trial registration The study is registered at clinicaltrials.gov under accession number NCT01676974. PMID:24775515

Architecture for an integrated real-time air combat and sensor network simulation

NASA Astrophysics Data System (ADS)

Criswell, Evans A.; Rushing, John; Lin, Hong; Graves, Sara

2007-04-01

An architecture for an integrated air combat and sensor network simulation is presented. The architecture integrates two components: a parallel real-time sensor fusion and target tracking simulation, and an air combat simulation. By integrating these two simulations, it becomes possible to experiment with scenarios in which one or both sides in a battle have very large numbers of primitive passive sensors, and to assess the likely effects of those sensors on the outcome of the battle. Modern Air Power is a real-time theater-level air combat simulation that is currently being used as a part of the USAF Air and Space Basic Course (ASBC). The simulation includes a variety of scenarios from the Vietnam war to the present day, and also includes several hypothetical future scenarios. Modern Air Power includes a scenario editor, an order of battle editor, and full AI customization features that make it possible to quickly construct scenarios for any conflict of interest. The scenario editor makes it possible to place a wide variety of sensors including both high fidelity sensors such as radars, and primitive passive sensors that provide only very limited information. The parallel real-time sensor network simulation is capable of handling very large numbers of sensors on a computing cluster of modest size. It can fuse information provided by disparate sensors to detect and track targets, and produce target tracks.

Developmental Biology and Regenerative Medicine: Addressing the Vexing Problem of Persistent Muscle Atrophy in the Chronically Torn Human Rotator Cuff.

PubMed

Meyer, Gretchen A; Ward, Samuel R

2016-05-01

Persistent muscle atrophy in the chronically torn rotator cuff is a significant obstacle for treatment and recovery. Large atrophic changes are predictive of poor surgical and nonsurgical outcomes and frequently fail to resolve even following functional restoration of loading and rehabilitation. New insights into the processes of muscle atrophy and recovery gained through studies in developmental biology combined with the novel tools and strategies emerging in regenerative medicine provide new avenues to combat the vexing problem of muscle atrophy in the rotator cuff. Moving these treatment strategies forward likely will involve the combination of surgery, biologic/cellular agents, and physical interventions, as increasing experimental evidence points to the beneficial interaction between biologic therapies and physiologic stresses. Thus, the physical therapy profession is poised to play a significant role in defining the success of these combinatorial therapies. This perspective article will provide an overview of the developmental biology and regenerative medicine strategies currently under investigation to combat muscle atrophy and how they may integrate into the current and future practice of physical therapy. © 2016 American Physical Therapy Association.

The effect of post traumatic stress disorders on rehabilitation among combat-wounded veterans.

In June 2008 the Congressionally Directed Medical Research Program provided a grant to the Research Foundation at the James A Haley Veterans Hospital in Tampa, Florida to provide care for wounded veterans from Operation Enduring Freedom (Afghanistan) and Operation Iraqi Freedom (OEF/OIF). The telerehabilitation for OEF/OIF returnees with mild or moderate combat related Traumatic Brain Injury (TBI) has as its objectives 1) care coordination for wounded veterans using distance technology via the internet and 2) monitoring of physical and mental health outcomes using a variety of instruments. A total of 75 veterans were enrolled in the study. Our initial findings indicate that 1) Functional capabilities measured by locomotion and mobility appear to have stabilized among our cohort of veterans while deficiencies in cognition (memory, problem solving), psychosocial adjustment (anger, emotional status) and problems in integrating into society pose challenges 2) Those with comorbid PTSD appear to linger in employability and ultimate integration into society as compared to those without the diagnosis 3) Individualized treatment pathways are needed for rehabilitation and ultimate integration into society.

The high angle-of-attack envelope clearance approach will be described, including a brief explanation of analysis techniques and tools. Also, problems encountered during envelope expansion will be discussed. This presentation emphasizes control system solutions to problems encountered in envelope expansion. An essentially 'care free' envelope was cleared for the close-in-combat demonstrator phase. High angle-of-attack flying qualities maneuvers are currently being flown and evaluated. These results are compared with pilot opinions expressed during the close-in-combat program and with results obtained from the F-18 HARV for identical maneuvers. The status and preliminary results of these tests are discussed.

The development of turbojet aircraft in Germany, Britain, and the United States: A multi-national comparison of aeronautical engineering, 1935--1946

NASA Astrophysics Data System (ADS)

Pavelec, Sterling Michael

In the 1930s aeronautical engineering needed revision. A presumptive anomaly was envisaged as piston-engine aircraft flew higher and faster. Radical alternatives to piston engines were considered in the unending quest for speed. Concurrently, but unwittingly, two turbojet engine programs were undertaken in Europe. The air-breathing three-stage turbojet engine was based on previous turbine technology; the revolutionary idea was the gas turbine as a prime mover for aircraft. In Germany, Dr. Hans von Ohain was the first to complete a flight-worthy turbojet engine for aircraft. Installed in a Heinkel designed aircraft, the Germans began the jet age on 27 August 1939. The Germans led throughout the war and were the first to produce jet aircraft for combat operations. The principal limiting factor for the German jet program was a lack of reliable engines. The continuing myths that Hitler orders, too little fuel, or too few pilots hindered the program are false. In England, Frank Whittle, without substantial support, but with dogged determination, also developed a turbojet engine. The British came second in the jet race when the Whittle engine powered the Gloster Pioneer on 15 May 1941. The Whittle-Gloster relationship continued and produced the only Allied combat jet aircraft during the war, the Meteor, which was confined to Home Defense in Britain. The American turbojet program was built directly from the Whittle engine. General Electric copied the Whittle designs and Bell Aircraft was contracted to build the first American jet plane. The Americans began the jet age on 1 October 1942 with a lackluster performance from their first jet, the Airacomet. But the Americans forged ahead, and had numerous engine and airframe programs in development by the end of the war. But, the Germans did it right and did it first. Partly because of a predisposition towards excellent engineering and physics, partly out of necessity, the Germans were able to produce combat turbojet aircraft during the war. The Allies lagged from a lack of necessity, operational incompatibility, and stringent acceptance requirements. By the end of the war the Germans needed qualitative technological superiority to combat an overwhelming Allied quantitative advantage.

This study examined whether individuals who were instructed on the Diagnostic and Statistical Manual of Mental Disorders (4th ed. [DSM-IV]; American Psychiatric Association, 1994) criteria for posttraumatic stress disorder (PTSD) could feign PTSD on the Personality Assessment Inventory (PAI; Morey, 1991). The study also investigated whether PAI indexes of symptom exaggeration, the Negative Impression Management (NIM) scale and the Malingering index, could identify individuals feigning PTSD. The diagnostic rule for PTSD (Morey, 1991, 1996) was applied to the profiles of a group of 23 veterans with combat-related PTSD and 23 male undergraduates instructed to malinger PTSD. Seventy percent of the student malingerers produced profiles that received diagnostic consideration for PTSD. The NIM cutting score (> or = 8) was highly effective in detecting simulation of PTSD but resulted in the misclassification of a large number of true PTSD cases. There were no significant differences in the overall efficiency of the test with various validity criteria. We discuss the implications of these findings for the use of the PAI in the diagnosis of combat-related PTSD.

Family perceptions of post‐deployment healthcare needs of Iraq/Afghanistan military personnel

PubMed Central

2010-01-01

Nearly 40 000 service members returning from Iraq and Afghanistan have suffered traumatic injuries, with over 300 000 at risk for post‐traumatic stress disorder (PTSD) or other psychiatric problems. These veterans face numerous post‐deployment health concerns, sharing substantial burdens with their families. Although many rely upon community‐based health care, little is known about how these individuals present at family medicine clinics for perceived medical and psychological issues. We surveyed 347 patients during visits at six clinics, and respondents reported whether they,a family member or a close acquaintance had been deployed since 2001. Patients identified traumatic military experiences, plus any attributable health or social problems. The mean patient age was 47.5 years, with 71% women and 55% Hispanic individuals. Nearly one‐quarter reported family members serving overseas while 52% knew someone deployed. Significant events included nearby explosion (21%) or combat injury (9%), along with a variety of other incidents. Among the half of individuals perceiving significant health or social ramifications, the most prevalent consequences were PTSD, depression and alcohol abuse. Divorce or marital problems were noted by13%, while many reported employment, legal or other difficulties. This study offers insights into post‐deployment needs of military personnel and subsequent problems reported by family members. A high prevalence of traumatic combat events translated into serious health needs, plus social disruptions for veterans and their loved ones. As the long‐term problems disclosed by returning service personnel continue to ripple across community clinics and other health systems, effective treatment planning mandates coordinated attention from multiple providers and service organisations.

Military service members may be prone to relapse to problem drinking after remission, given a culture of alcohol use as a coping mechanism for stressful or traumatic events associated with military duties or exposures. However, the prevalence and correlates of relapse are unknown. We sought to identify socio-demographic, military, behavioral, and health characteristics associated with relapse among current and former military members with remittent problem drinking. Participants in the longitudinal Millennium Cohort Study who reported problem drinking at baseline (2001-2003) and were remittent at first follow-up (2004-2006) were included (n=6909). Logistic regression models identified demographic, military service, behavioral, and health characteristics that predicted relapse (report of ≥1 past-year alcohol-related problem on the validated Patient Health Questionnaire) at the second follow-up (2007-2008). Sixteen percent of those with remittent problem drinking relapsed. Reserve/National Guard members compared with active-duty members (odds ratio [OR]=1.71, 95% confidence interval [CI]: 1.45-2.01), members separated from the military during follow-up (OR=1.46, 95% CI: 1.16-1.83), and deployers who reported combat exposure (OR=1.32, 95% CI: 1.07-1.62, relative to non-deployers) were significantly more likely to relapse. Those with multiple deployments were significantly less likely to relapse (OR=0.73, 95% CI: 0.58-0.92). Behavioral factors and mental health conditions also predicted relapse. Relapse was common and associated with military and non-military factors. Targeted intervention to prevent relapse may be indicated for military personnel in particular subgroups, such as Reservists, veterans, and those who deploy with combat exposure. Copyright © 2015.

Research into violence among military personnel has not differentiated between stranger- and family-directed violence. While military factors (combat exposure and post-deployment mental health problems) are risk factors for general violence, there has been limited research on their impact on violence within the family environment. This study aims to compare the prevalence of family-directed and stranger-directed violence among a deployed sample of UK military personnel and to explore risk factors associated with both family- and stranger-directed violence. This study utilised data from a large cohort study which collected information by questionnaire from a representative sample of randomly selected deployed UK military personnel (n = 6711). The prevalence of family violence immediately following return from deployment was 3.6% and 7.8% for stranger violence. Family violence was significantly associated with having left service, while stranger violence was associated with younger age, male gender, being single, having a history of antisocial behaviour as well as having left service. Deployment in a combat role was significantly associated with both family and stranger violence after adjustment for confounders [adjusted odds ratio (aOR) = 1.92 (1.25-2.94), p = 0.003 and aOR = 1.77 (1.31-2.40), p < 0.001, respectively], as was the presence of symptoms of post-traumatic stress disorder, common mental disorders and aggression. Exposure to combat and post-deployment mental health problems are risk factors for violence both inside and outside the family environment and should be considered in violence reduction programmes for military personnel. Further research using a validated measurement tool for family violence would improve comparability with other research.

Energy drink consumption and its association with sleep problems among U.S. service members on a combat deployment - Afghanistan, 2010.

PubMed

2012-11-09

Beverages marketed as energy drinks have become a popular form of caffeine consumption targeted at young males, with some brands containing the caffeine equivalent of 1-3 cups of coffee or cans of soda. Energy drinks also include other ingredients intended to boost physical energy or mental alertness, such as herbal substances, amino acids, sugars, and sugar derivatives; however, caffeine is the main active ingredient. Approximately 6% of adolescent and young adult males in U.S. civilian and military populations consume energy drinks daily. These products generally are unregulated and can have negative side effects (e.g., caffeine intoxication, overdose, withdrawal, and poor interactions with alcohol). Paradoxically, excess consumption also can increase sleep problems and daytime sleepiness, which can impair performance. To determine the extent of energy drink use and the association with sleep problems and sleepiness during combat operations, Walter Reed Army Institute of Research analyzed data collected by Joint Mental Health Advisory Team 7 (J-MHAT 7) to Operation Enduring Freedom in Afghanistan in 2010. The analysis showed that 44.8% of deployed service members consumed at least one energy drink daily, with 13.9% drinking three or more a day. No differences by age or rank were found. Service members drinking three or more energy drinks a day were significantly more likely to report sleeping ≤4 hours a night on average than those consuming two drinks or fewer. Those who drank three or more drinks a day also were more likely to report sleep disruption related to stress and illness and were more likely to fall asleep during briefings or on guard duty. Service members should be educated regarding the potential adverse effects of excessive energy drink consumption on sleep and mission performance and should be encouraged to moderate their energy drink consumption in combat environments.

2015-05-01

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

Plastic Surgery Challenges in War Wounded I: Flap-Based Extremity Reconstruction

PubMed Central

Sabino, Jennifer M.; Slater, Julia; Valerio, Ian L.

2016-01-01

Scope and Significance: Reconstruction of traumatic injuries requiring tissue transfer begins with aggressive resuscitation and stabilization. Systematic advances in acute casualty care at the point of injury have improved survival and allowed for increasingly complex treatment before definitive reconstruction at tertiary medical facilities outside the combat zone. As a result, the complexity of the limb salvage algorithm has increased over 14 years of combat activities in Iraq and Afghanistan. Problem: Severe poly-extremity trauma in combat casualties has led to a large number of extremity salvage cases. Advanced reconstructive techniques coupled with regenerative medicine applications have played a critical role in the restoration, recovery, and rehabilitation of functional limb salvage. Translational Relevance: The past 14 years of war trauma have increased our understanding of tissue transfer for extremity reconstruction in the treatment of combat casualties. Injury patterns, flap choice, and reconstruction timing are critical variables to consider for optimal outcomes. Clinical Relevance: Subacute reconstruction with specifically chosen flap tissue and donor site location based on individual injuries result in successful tissue transfer, even in critically injured patients. These considerations can be combined with regenerative therapies to optimize massive wound coverage and limb salvage form and function in previously active patients. Summary: Traditional soft tissue reconstruction is integral in the treatment of war extremity trauma. Pedicle and free flaps are a critically important part of the reconstructive ladder for salvaging extreme extremity injuries that are seen as a result of the current practice of war. PMID:27679751

Combat stressors and post-traumatic stress in deployed military healthcare professionals: an integrative review.

Gibbons, Susanne W; Hickling, Edward J; Watts, Dorraine D

2012-01-01

  While there has been a growing body of literature on the impact of combat stressors and post-traumatic stress on military service members involved in current conflicts, there has been little available information that directly examines the impact of these on healthcare providers. Aims for this integrative review included: (1) identifying exposures, experiences and other factors influencing stress responses in military healthcare providers previously engaged in a war effort and (2) describing the incidence of post-traumatic stress and related mental health problems in this population. Using Cooper's integrative review method, relevant documents were collected and analysed using content categories and a coding scheme to assist with identifying and recording data for units of analysis. Literature searches (including all years to present) were conducted using keywords for stress reaction, for healthcare provider and for military war effort involvement. Literature was obtained using the Cumulative Index to Nursing and Allied Health Literature, the National Library of Medicine and the American Psychological Association databases. Evidence suggests that similar to military combatants, military healthcare provider exposure to life-threatening situations will increase the probability of adverse psychological disorders following these traumatic experiences. The presence of a strong sense of meaning and purpose, within a supportive environment appear to help mediate the impact of these dangerous and stressful events. Results of this review and other supporting literature indicate the need for a systematic approach to studying combat stress and post-traumatic stress in deployed healthcare providers. © 2011 Blackwell Publishing Ltd.

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

PubMed

Nindl, Bradley C

2015-11-01

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

Comparison of combat and non-combat burns from ongoing U.S. military operations.

2006-05-15

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

The rapid onset of resistance reduces the efficacy of most conventional antimicrobial drugs and is a general cause of concern for human well-being. Thus, there is great demand for a continuous supply of novel antibiotics to combat this problem. Bacteria-derived antimicrobial peptides (AMPs) have long been used as food preservatives; moreover, prior to the development of conventional antibiotics, these AMPs served as an efficient source of antibiotics. Recently, peptides produced by members of the genus Bacillus were shown to have a broad spectrum of antimicrobial activity against pathogenic microbes. Bacillus-derived AMPs can be synthesized both ribosomally and nonribosomally and can be classified according to peptide biosynthesis, structure, and molecular weight. The precise mechanism of action of these AMPs is not yet clear; however, one proposed mechanism is that these AMPs kill bacteria by forming channels in and (or) disrupting the bacterial cell wall. Bacillus-derived AMPs have potential in the pharmaceutical industry, as well as the food and agricultural sectors. Here, we focus on Bacillus-derived AMPs as a novel alternative approach to antibacterial drug development. We also provide an overview of the biosynthesis, mechanisms of action, applications, and effectiveness of different AMPs produced by members of the Bacillus genus, including several recently identified novel AMPs.

Clostridium novyi causes necrotic hepatitis in sheep and cattle, as well as gas gangrene. The microorganism is strictly anaerobic, fastidious, and difficult to cultivate in industrial scale. C. novyi type B produces alpha and beta toxins, with the alpha toxin being linked to the presence of specific bacteriophages. The main strategy to combat diseases caused by C. novyi is vaccination, employing vaccines produced with toxoids or with toxoids and bacterins. In order to identify culture medium components and concentrations that maximized cell density and alpha toxin production, a neuro-fuzzy algorithm was applied to predict the yields of the fermentation process for production of C. novyi type B, within a global search procedure using the simulated annealing technique. Maximizing cell density and toxin production is a multi-objective optimization problem and could be treated by a Pareto approach. Nevertheless, the approach chosen here was a step-by-step one. The optimum values obtained with this approach were validated in laboratory scale, and the results were used to reload the data matrix for re-parameterization of the neuro-fuzzy model, which was implemented for a final optimization step with regards to the alpha toxin productivity. With this methodology, a threefold increase of alpha toxin could be achieved.

Automatic fall detection will promote independent living and reduce the consequences of falls in the elderly by ensuring people can confidently live safely at home for linger. In laboratory studies inertial sensor technology has been shown capable of distinguishing falls from normal activities. However less than 7% of fall-detection algorithm studies have used fall data recorded from elderly people in real life. The FARSEEING project has compiled a database of real life falls from elderly people, to gain new knowledge about fall events and to develop fall detection algorithms to combat the problems associated with falls. We have extracted 12 different kinematic, temporal and kinetic related features from a data-set of 89 real-world falls and 368 activities of daily living. Using the extracted features we applied machine learning techniques and produced a selection of algorithms based on different feature combinations. The best algorithm employs 10 different features and produced a sensitivity of 0.88 and a specificity of 0.87 in classifying falls correctly. This algorithm can be used distinguish real-world falls from normal activities of daily living in a sensor consisting of a tri-axial accelerometer and tri-axial gyroscope located at L5.

Resilience Training has the potential to mitigate mental health symptoms when provided during initial military training. The present study examined the impact of Resilience Training on US soldier well-being and attitudes during Basic Combat Training. Platoons were randomly assigned to Resilience Training or Military History provided during the first few days of Basic Combat Training. Surveys were conducted at baseline, post-intervention, and 3, 6, and 9 weeks. The sample resulted in a total of 1,939 soldiers who completed at least the baseline and one follow-up survey. There were no significant differences between conditions in terms of depression symptoms, anxiety symptoms, or sleep problems. However, while anxiety decreased in both conditions, the rate of decrease was faster in the Resilience Training condition. In contrast, Resilience Training had a slower rate of increase in group cohesion over time than the Military History condition. In addition, Resilience Training was associated with greater confidence in helping others and received more positive ratings than Military History. Findings demonstrate that the brief Resilience Training studied here may have some utility in supporting mental health and peer support but may not benefit unit climate. © 2014 The International Association of Applied Psychology.

U.S. combat veterans frequently encounter challenges after returning from deployment, and these challenges may lead to difficulties in psychological and social functioning. Currently, research is limited on gender-related differences within this population, despite female veterans comprising a growing portion of the U.S. military with roles and exposures similar to their male counterparts. Using secondary analysis, we examined 283 returning combat veterans (female = 29.4%) for differences in psychopathology and trauma history. Female veterans were more likely to report a history of sexual trauma than their male counterparts, whereas male veterans were more likely to report greater frequency of gambling in the past year, impulsivity, and hypersexuality. No gender-related differences were identified for depression, anxiety, insomnia, or substance-use disorders, although both men and women veterans had higher rates than those found in the general population. While both male and female combat veterans report various mental health problems as they transition back into civilian life, gender-related differences relating to sexual trauma, hypersexuality, and impulsivity warrant additional investigations with respect to the potential impact they may have on veteran reintegration and treatment.

Rural Women Veterans' Use and Perception of Mental Health Services.

Ingelse, Kathy; Messecar, Deborah

2016-04-01

While the total number of veterans in the U.S. is decreasing overall, the number of women veterans is significantly increasing. There are numerous barriers which keep women veterans from accessing mental health care. One barrier which can impact receiving care is living in a rural area. Veterans in rural areas have access to fewer mental health services than do urban residing veterans, and women veterans in general have less access to mental health care than do their male colleagues. Little is known about rural women veterans and their mental health service needs. Women, who have served in the military, have unique problems related to their service compared to their male colleagues including higher rates of post-traumatic stress disorder (PTSD) and military sexual trauma (MST). This qualitative study investigated use of and barriers to receiving mental health care for rural women veterans. In-depth interviews were conducted with ten women veterans who have reported experiencing problems with either MST, PTSD, or combat trauma. All ten women had utilized mental health services during active-duty military service, and post service, in Veterans Administration (VA) community based-outpatient clinics. Several recurring themes in the women's experience were identified. For all of the women interviewed, a sentinel precipitating event led to seeking mental health services. These precipitating events included episodes of chronic sexual harassment and ridicule, traumatic sexual assaults, and difficult combat experiences. Efforts to report mistreatment were unsuccessful or met with punishment. All the women interviewed reported that they would not have sought services without the help of a supportive peer who encouraged seeking care. Barriers to seeking care included feeling like they were not really a combat veteran (in spite of serving in a combat unit in Iraq); feeling stigmatized by providers and other military personnel, being treated as crazy; and a lack of interest from those providing care in hearing their stories. This study may generate positive social change by helping providers approach women veterans in a way that is sympathetic to their experiences. Copyright © 2015 Elsevier Inc. All rights reserved.

Antibiotics: natural products essential to human health.

PubMed

Demain, Arnold L

2009-11-01

For more than 50 years, natural products have served us well in combating infectious bacteria and fungi. Microbial and plant secondary metabolites helped to double our life span during the 20th century, reduced pain and suffering, and revolutionized medicine. Most antibiotics are either (i) natural products of microorganisms, (ii) semi-synthetically produced from natural products, or (iii) chemically synthesized based on the structure of the natural products. Production of antibiotics began with penicillin in the late 1940s and proceeded with great success until the 1970-1980s when it became harder and harder to discover new and useful products. Furthermore, resistance development in pathogens became a major problem, which is still with us today. In addition, new pathogens are continually emerging and there are still bacteria that are not eliminated by any antibiotic, e.g., Pseudomonas aeruginosa. In addition to these problems, many of the major pharmaceutical companies have abandoned the antibiotic field, leaving much of the discovery efforts to small companies, new companies, and the biotechnology industries. Despite these problems, development of new antibiotics has continued, albeit at a much lower pace than in the last century. We have seen the (i) appearance of newly discovered antibiotics (e.g., candins), (ii) development of old but unutilized antibiotics (e.g., daptomycin), (iii) production of new semi-synthetic versions of old antibiotics (e.g., glycylcyclines, streptogrammins), as well as the (iv) very useful application of old but underutilized antibiotics (e.g., teicoplanin).

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

Building health research systems: WHO is generating global perspectives, and who's celebrating national successes?

Hanney, Stephen R; González-Block, Miguel A

2016-12-28

In 2016, England's National Institute for Health Research (NIHR) celebrated its tenth anniversary as an innovative national health research system with a focus on meeting patients' needs. This provides a good opportunity to reflect on how the creation of the NIHR has greatly enhanced important work, started in 1991, to develop a health research system in England that is embedded in the National Health Service.In 2004, WHO identified a range of functions that a national health research system should undertake to improve the health of populations. Health Research Policy and Systems (HRPS) has taken particular interest in the pioneering developments in the English health research system, where the comprehensive approach has covered most, if not all, of the functions identified by WHO. Furthermore, several significant recent developments in thinking about health research are relevant for the NIHR and have informed accounts of its achievements. These include recognition of the need to combat waste in health research, which had been identified as a global problem in successive papers in the Lancet, and an increasing emphasis on demonstrating impact. Here, pioneering evaluation of United Kingdom research, conducted through the impact case studies of the Research Excellence Framework, is particularly important. Analyses informed by these and other approaches identified many aspects of NIHR's progress in combating waste, building and sustaining research capacity, creating centres of research excellence linked to leading healthcare institutions, developing research networks, involving patients and others in identifying research needs, and producing and adopting research findings that are improving health outcomes.The NIHR's overall success, and an analysis of the remaining problems, might have lessons for other systems, notwithstanding important advances in many countries, as described in papers in HRPS and elsewhere. WHO's recently established Global Observatory for Health Research and Development provides an opportunity to promote some of these lessons. To inform its work, the Observatory is sponsoring a thematic series of papers in HRPS focusing on health research issues such as funding flows, priority setting, capacity building, utilisation and equity. While important papers on these have been published, this series is still open to new submissions.

Conceptual modeling of postmortem evaluation findings to describe dairy cow deaths.

McConnel, C S; Garry, F B; Hill, A E; Lombard, J E; Gould, D H

2010-01-01

Dairy cow mortality levels in the United States are excessive and increasing over time. To better define cause and effect and combat rising mortality, clearer definitions of the reasons that cows die need to be acquired through thorough necropsy-based postmortem evaluations. The current study focused on organizing information generated from postmortem evaluations into a monitoring system that is based on the fundamentals of conceptual modeling and that will potentially be translatable into on-farm relational databases. This observational study was conducted on 3 high-producing, commercial dairies in northern Colorado. Throughout the study period a thorough postmortem evaluation was performed by veterinarians on cows that died on each dairy. Postmortem data included necropsy findings, life-history features (e.g., birth date, lactation number, lactational and reproductive status), clinical history and treatments, and pertinent aspects of operational management that were subject to change and considered integral to the poor outcome. During this study, 174 postmortem evaluations were performed. Postmortem evaluation results were conceptually modeled to view each death within the context of the web of factors influencing the dairy and the cow. Categories were formulated describing mortality in terms of functional characteristics potentially amenable to easy performance evaluation, management oversight, and research. In total, 21 death categories with 7 category themes were created. Themes included specific disease processes with variable etiologies, failure of disease recognition or treatment, traumatic events, multifactorial failures linked to transition or negative energy balance issues, problems with feed management, miscellaneous events not amenable to prevention or treatment, and undetermined causes. Although postmortem evaluations provide the relevant information necessary for framing a cow's death, a restructuring of on-farm databases is needed to integrate this level of detail into useful monitoring systems. Individual operations can focus on combating mortality through the use of employee training related to postmortem evaluations, detailed forms for capturing necropsy particulars and other relevant information related to deaths, and standardized nomenclature and categorization schemes. As much as anything, the simple act of recognizing mortality as a problem might be the most fundamental step toward controlling its progression. Copyright 2010 American Dairy Science Association.

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

2016-01-01

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

Preventing teen pregnancy through persuasive communications: realities, myths, and the hard-fact truths.

PubMed

Witte, K

1997-04-01

Effective campaigns are desperately needed to combat the serious social problem of teen pregnancy. However, public health campaigns are most often noted for failures, rather than successes. One reason for a campaign failing to have the intended effect is lack of theoretical guidance at the formative evaluation stage. The study reported here is a theoretically-based formative evaluation with inner city teens. Six focus groups were conducted to determine knowledge, attitudes, beliefs, and recommendations for effective campaigns to deter teen pregnancy. The results indicate that campaign messages need to combat positive attitudes toward pregnancy, negative attitudes toward birth control, the perception of personal invulnerability, and emphasize the negative consequences of sexual intercourse. This study's findings also suggest that campaigns with these messages need to start at an early age in order to effectively prevent teen pregnancy.

Orsillo, S M; Heimberg, R G; Juster, H R; Garrett, J

1996-04-01

Posttraumatic stress disorder (PTSD) is the most prevalent psychological disorder experienced by Vietnam veterans. However, there are many other disorders and problems of adjustment, like social anxiety and social phobia, that have not been fully investigated in this population. This study examined the prevalence of social phobia and the comorbidity of social phobia and PTSD, and tested out a theory of the etiology of social anxiety in trauma victims. Forty one Vietnam combat veterans were interviewed and completed self-report measures assessing PTSD and social phobia. Adversity of homecoming was also assessed. Using a conservative multi-method assessment approach, 32% of the sample were found to be positive for both social phobia and PTSD. Veterans with PTSD were significantly more likely to carry an additional diagnosis of social phobia as compared to veterans without PTSD. Adversity of homecoming and shame about one's experience in Vietnam were significant predictors of current level of social anxiety over and above the effects of pre-military anxiety and severity of combat exposure. These observations suggest that social anxiety and social phobia may be significant problems among individuals with PTSD. Further, these findings offer preliminary support for the theory that posttrauma environment may impact upon the later development of social anxiety.

Brain Response to Primary Blast Wave Using Validated Finite Element Models of Human Head and Advanced Combat Helmet

PubMed Central

Zhang, Liying; Makwana, Rahul; Sharma, Sumit

2013-01-01

Blast-induced traumatic brain injury has emerged as a “signature injury” in combat casualty care. Present combat helmets are designed primarily to protect against ballistic and blunt impacts, but the current issue with helmets is protection concerning blasts. In order to delineate the blast wave attenuating capability of the Advanced Combat Helmet (ACH), a finite element (FE) study was undertaken to evaluate the head response against blast loadings with and without helmet using a partially validated FE model of the human head and ACH. Four levels of overpressures (0.27–0.66 MPa) from the Bowen’s lung iso-damage threshold curves were used to simulate blast insults. Effectiveness of the helmet with respect to head orientation was also investigated. The resulting biomechanical responses of the brain to blast threats were compared for human head with and without the helmet. For all Bowen’s cases, the peak intracranial pressures (ICP) in the head ranged from 0.68 to 1.8 MPa in the coup cortical region. ACH was found to mitigate ICP in the head by 10–35%. Helmeted head resulted in 30% lower average peak brain strains and product of strain and strain rate. Among three blast loading directions with ACH, highest reduction in peak ICP (44%) was due to backward blasts whereas the lowest reduction in peak ICP and brain strains was due to forward blast (27%). The biomechanical responses of a human head to primary blast insult exhibited directional sensitivity owing to the different geometry contours and coverage of the helmet construction and asymmetric anatomy of the head. Thus, direction-specific tolerances are needed in helmet design in order to offer omni-directional protection for the human head. The blasts of varying peak overpressures and durations that are believed to produce the same level of lung injury produce different levels of mechanical responses in the brain, and hence “iso-damage” curves for brain injury are likely different than the Bowen curves for lung injury.

Optimizing Opto-mechanical Performance Using Simple Tools and Techniques

NASA Astrophysics Data System (ADS)

Krajci, Tom

2009-05-01

You just purchased a modest setup for your observatory - perhaps a mass produced Schmidt-Cassegrain on a German equatorial mount. However, optically and mechanically it's not performing as well as you would like. What can you do? Some simple assessments and repairs may make all the difference. Assessments can be as easy as visual inspection of various mount components, such as the tripod, where gaps between components reduce stiffness or allow unexpected shifts when loads change. Some assessments are only slightly more involved. Main mirror flop can be evaluated by aligning the main telescope and finder on a bright star and then slewing to various parts of the sky. Pointing differences between the two will be readily apparent if this problem exists. Most mid-level mounts use worm drives, but often excessive spacing between worm and worm gear produces large, and unnecessary amounts of backlash. Visual inspection of your dovetail mounting system may leave doubts in your mind as to adequate stiffness. Imaging through the entire night may show you that your aluminum tube telescope causes excessive focus shift as temperature drops. Over time, your Schmidt-Cassegrain corrector plate may no longer be securely held by its retaining ring, and the same may apply to the secondary mirror cell. Repairs for these problems are often not difficult if you're mechanically inclined. Gaps in mount components can be eliminated with shims. Combating mirror flop may be the most difficult task. This can involve re-gluing the main mirror and bolting the main mirror cell in a fixed position. Corrector plate and secondary mirror cells can be improved with setscrews and shims - implementing sound kinematic principles. Worm gear spacing can often be adjusted with simple tools. This brief paper can't possibly cover all problems and solutions, but it can give you the proper mindset to looking at your system with a critical eye and implementing simple, inexpensive fixes. You may be pleasantly surprised by the improvements.

Fratricide is a major problem in combat operations involving military vehicles. In this research, we aimed to evaluate the effects of training on CID performance in order to reduce fratricide errors. Individuals were trained on 12 combat vehicles in a simulation, which were presented via either a non-stereoscopic or active stereoscopic display using NVIDIA's GeForce shutter glass technology. Self-report was used to assess video game experience, leading to four between-subjects groups: high video game experience with stereoscopy, low video game experience with stereoscopy, high video game experience without stereoscopy, and low video game experience without stereoscopy. We then tested participants on their memory of each vehicle's alliance and name across multiple measures, including photographs and videos. There was a main effect for both video game experience and stereoscopy across many of the dependent measures. Further, we found interactions between video game experience and stereoscopic training, such that those individuals with high video game experience in the non-stereoscopic group had the highest performance outcomes in the sample on multiple dependent measures. This study suggests that individual differences in video game experience may be predictive of enhanced performance in CID tasks. Selection based on video game experience in CID tasks may be a useful strategy for future military training. Future research should investigate the generalizability of these effects, such as identification through unmanned vehicle sensors.

Partners of Australian combat veterans are at an increased risk of experiencing mental health problems. The present study provides a comparative analysis of the mental health of partners of veterans with that of the Australian normative data. To compare different types of groups of partners, the study samples comprised: (a) partners of Australian combat veterans (Sample 1: n = 282, age M = 60.79, SD = 5.05), (b) a sub-sample of partners of Australian combat veterans from the previous sample (Sample 2: n = 50; M = 60.06, SD = 4.80), (c) partners of Special Air Services Regiment (SASR) personnel (Sample 3: n = 40, age M = 34.39SD = 7.01), and (d) partners of current serving military (non-SASR) personnel (Sample 4: n = 38, age M = 32.37, SD = 6.20). Respondents completed measures assessing their reported levels of depression, anxiety, and stress. Samples 1 and 2 comprised partners of Australian military veterans who reported significantly greater symptoms of depression, anxiety, and stress than the comparative population norms. The sample of SASR personnel partners (Sample 3) reported significantly lower levels of depression and anxiety, whereas the sample with non-SASR personnel partners (Sample 4) reported a significantly greater stress symptomatology than the comparative norms. Number of deployments was found to be associated with depression, anxiety, and stress in partners of non-SASR veterans (Sample 4). Lessons and protective factors can be learnt from groups within the current military as to what may assist partners and families to maintain a better level of psychosocial health.

Unwanted pregnancies and the subsequent induced abortions are common problems of our youths in modern Greece. The aim of this study was to recognize the risk factors of the problem in an effort to find the best possible solution out of this social dead end. We interviewed 1,320 young female individuals and analyzed their answers using statistical analysis. Several useful conclusions were reached concerning the forces that are involved in unwanted pregnancy/induced abortions. We have tried to underline the strategy to combat the problem. Sexual education and the proper use of contraception remain the essential tools in this effort.

Historical development of worldwide supersonic aircraft

NASA Technical Reports Server (NTRS)

Spearman, M. L.

1983-01-01

Some major milestones in the progression of airplane speeds from subsonic to supersonic are traced. Historical background is included on work done prior to the Twentieth Century, but the major emphasis is on the Twentieth Century developments after the man carrying airplane became a practical reality. The techniques of increasing airplane speed revolve around means of increasing the propulsive force and means of reducing the airframe resistance (drag). With the changes in speed, the attendant changes in flow patterns due to the compressibility of air introduce some aerodynamic problems. In addition, geometric changes introduced to combat the effects of compressibility also promote aerodynamic problems. Some of the solutions to these problems are illustrated, and many design features that evolved are discussed.

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

PubMed

Ashley, Wendy; Brown, Jodi Constantine

2015-01-01

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

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

2015-01-01

Background Compared to DSM-IV, the criteria for diagnosing posttraumatic stress disorder (PTSD) have been modified in DSM-5. Objective The first aim of this study was to examine how these modifications impact rates of PTSD in a sample of Congolese ex-combatants. The second goal of this study was to investigate whether PTSD symptoms were associated with perpetrator-related acts or victim-related traumatic events. Method Ninety-five male ex-combatants in the eastern Democratic Republic of Congo were interviewed. Both the DSM-IV and the DSM-5 PTSD symptom criteria were assessed. Results The DSM-5 symptom criteria yielded a PTSD rate of 50% (n=47), whereas the DSM-IV symptom criteria were met by 44% (n=42). If the DSM-5 would be set as the current “gold standard,” then DSM-IV would have produced more false negatives (8%) than false positives (3%). A minority of participants (19%, n=18) indicated an event during which they were involved as a perpetrator as their most stressful event. Results of a regression analysis (R 2=0.40) showed that, after accounting for the number of types of traumatic events, perpetrated violent acts were not associated with the symptom severity of PTSD. Conclusions The findings demonstrate that more diagnostic cases were produced with the DSM-5 diagnostic rules than were dropped resulting in an increase in PTSD rates compared to the DSM-IV system. The missing association between PTSD symptoms and perpetrated violent acts might be explained by a potential fascinating and excited perception of these acts. PMID:25720994

Biodistance analysis of the Moche sacrificial victims from Huaca de la Luna plaza 3C: Matrix method test of their origins.

PubMed

Sutter, Richard C; Verano, John W

2007-02-01

The purpose of this study is to test two competing models regarding the origins of Early Intermediate Period (AD 200-750) sacrificial victims from the Huacas de Moche site using the matrix correlation method. The first model posits the sacrificial victims represent local elites who lost competitions in ritual battles with one another, while the other model suggests the victims were nonlocal warriors captured during warfare with nearby polities. We estimate biodistances for sacrificial victims from Huaca de la Luna Plaza 3C (AD 300-550) with eight previously reported samples from the north coast of Peru using both the mean measure of divergence (MMD) and Mahalanobis' distance (d2). Hypothetical matrices are developed based upon the assumptions of each of the two competing models regarding the origins of Moche sacrificial victims. When the MMD matrix is compared to the two hypothetical matrices using a partial-Mantel test (Smouse et al.: Syst Zool 35 (1986) 627-632), the ritual combat model (i.e. local origins) has a low and nonsignificant correlation (r = 0.134, P = 0.163), while the nonlocal origins model is highly correlated and significant (r = 0.688, P = 0.001). Comparisons of the d2 results and the two hypothetical matrices also produced low and nonsignificant correlation for the ritual combat model (r = 0.210, P = 0.212), while producing a higher and statistically significant result with the nonlocal origins model (r = 0.676, P = 0.002). We suggest that the Moche sacrificial victims represent nonlocal warriors captured in territorial combat with nearby competing polities. Copyright 2006 Wiley-Liss, Inc.

This visible light/infrared composite image over Montana and Idaho was acquired by the Moderate-resolution Imaging Spectroradiometer on Aug. 23, 2000. The image shows the locations of actively burning wildfires (red pixels) and the thick shroud of smoke they produced (grey-blue pixels). There were 57 wildfires burning across both states. A single MODIS image can be up to 2,330 kilometers wide, allowing fire scientists to monitor a much larger area than can be covered on the ground or by aircraft. Also, because MODIS has detectors that are sensitive to thermal infrared wavelengths of 3.70 and 3.90 micrometers, it can detect fires on the surface even through heavy smoke.

A field study was undertaken to investigate the effects of combined noise, vibration and heat stress on the physiological functions of the crew of armoured vehicles during prolonged combat exercise in a desert. The sound pressure level of noise was measured with a sound level meter and accelerations by vibration analyser. The thermal load on the crew was evaluated by calculating the wet bulb globe temperature index. The physiological responses of the subjects ( n=9), included significant increases in the heart rate, 24 h water intake and urinary catecholamine concentration. A significant decrease was recorded in body mass, peak expiratory flow rate and 24 h urinary output. The high heat load on the crew resulted in a hypohydration of 3% body mass and appeared to be the dominant factor in producing the physiological strain.

Environmental management of acid water problems in mining areas

Acid Mine Drainage (AMD) originates from the oxidation and leaching of sulphide minerals present in coal and metalliferrous ore bodies and gives rise to several environmental degradation problems. An investigation has been carried out to combat the acidic water problems. Results of this investigation indicate that application of anionic surfactant (sodium lauryl sulphate) and food preservatives (sodium benzoate and potassium sorbate) effectively abate the acid formation at low concentration levels (15-40 ppm) as tested in laboratory as well as at pilot-scale levels. Acidity, sulphate and iron concentrations are found to reduce by over 70 percent and remained low for more than three months after treatment. Thus this investigation demonstrates the management of these problems in an environmentally safe manner by controlling acid formation at its source.

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

PubMed

Netto, Kevin J; Burnett, Angus F

2006-10-01

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

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

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

Arsenic (As) contamination in groundwater has become a geo-environmental as well as a toxicological problem across the globe affecting more than 100-million people in nearly 21 countries with its associated disease "arsenicosis." Arsenic poisoning may lead to fatal skin and internal cancers. In present review, an attempt has been made to generate awareness among the readers about various sources of occurrence of arsenic, its geochemistry and speciation, mobilization, metabolism, genotoxicity, and toxicological exposure on humans. The article also emphasizes the possible remedies for combating the problem. The knowledge of these facts may help to work on some workable remedial measure.

Gun violence is a major threat to the public's health and safety in the United States. The articles in this volume's symposium on gun violence reveal the scope of the problem and new trends in mortality rates from gunfire. Leading scholars synthesize research evidence that demonstrates the ability of numerous policies and programs-each consistent with lessons learned from successful efforts to combat public health problems-to prevent gun violence. Each approach presents challenges to successful implementation. Future research should inform efforts to assess which approaches are most effective and how to implement evidence-based interventions most effectively.

1988-01-01

A pointing error model is used in the antenna calibration process. Data from spacecraft or radio star observations are used to determine the parameters in the model. However, the regression variables are not truly independent, displaying a condition known as multicollinearity. Ridge regression, a biased estimation technique, is used to combat the multicollinearity problem. Two data sets pertaining to Voyager 1 spacecraft tracking (days 105 and 106 of 1987) were analyzed using both linear least squares and ridge regression methods. The advantages and limitations of employing the technique are presented. The problem is not yet fully resolved.

Helminth parasites cause significant morbidity and mortality in endemic countries. Given the severity of symptoms that helminths may elicit in the host, intervention with prophylactic and therapeutic measures is imperative. Treatment with benzimidazoles is the most widely used means of combatting these parasites. However, widespread use of these drugs can select for drug-resistant parasite strains. In this review, we approach the problem of benzimidazole resistance in helminths in both humans and animals, focusing on the properties of the drug, the molecular mechanisms of drug resistance and how resistance is diagnosed.

The US military has conducted population-level screening for mental health problems among all service members returning from deployment to Afghanistan, Iraq, and other locations. To date, no systematic analysis of this program has been conducted, and studies have not assessed the impact of these deployments on mental health care utilization after deployment. To determine the relationship between combat deployment and mental health care use during the first year after return and to assess the lessons learned from the postdeployment mental health screening effort, particularly the correlation between the screening results, actual use of mental health services, and attrition from military service. Population-based descriptive study of all Army soldiers and Marines who completed the routine postdeployment health assessment between May 1, 2003, and April 30, 2004, on return from deployment to Operation Enduring Freedom in Afghanistan (n = 16,318), Operation Iraqi Freedom (n = 222,620), and other locations (n = 64,967). Health care utilization and occupational outcomes were measured for 1 year after deployment or until leaving the service if this occurred sooner. Screening positive for posttraumatic stress disorder, major depression, or other mental health problems; referral for a mental health reason; use of mental health care services after returning from deployment; and attrition from military service. The prevalence of reporting a mental health problem was 19.1% among service members returning from Iraq compared with 11.3% after returning from Afghanistan and 8.5% after returning from other locations (P<.001). Mental health problems reported on the postdeployment assessment were significantly associated with combat experiences, mental health care referral and utilization, and attrition from military service. Thirty-five percent of Iraq war veterans accessed mental health services in the year after returning home; 12% per year were diagnosed with a mental health problem. More than 50% of those referred for a mental health reason were documented to receive follow-up care although less than 10% of all service members who received mental health treatment were referred through the screening program. Combat duty in Iraq was associated with high utilization of mental health services and attrition from military service after deployment. The deployment mental health screening program provided another indicator of the mental health impact of deployment on a population level but had limited utility in predicting the level of mental health services that were needed after deployment. The high rate of using mental health services among Operation Iraqi Freedom veterans after deployment highlights challenges in ensuring that there are adequate resources to meet the mental health needs of returning veterans.

Marinobacter sp. from marine sediments produce highly stable surface-active agents for combatting marine oil spills.

2017-11-02

The application of chemical dispersants as a response to marine oil spills is raising concerns related to their potential toxicity also towards microbes involved in oil biodegradation. Hence, oil spills occurring under marine environments necessitate the application of biodispersants that are highly active, stable and effective under marine environment context. Biosurfactants from marine bacteria could be good candidates for the development of biodispersant formulations effective in marine environment. This study aimed at establishing a collection of marine bacteria able to produce surface-active compounds and evaluating the activity and stability of the produced compounds under conditions mimicking those found under marine environment context. A total of 43 different isolates were obtained from harbor sediments. Twenty-six of them produced mainly bioemulsifiers when glucose was used as carbon source and 16 were biosurfactant/bioemulsifiers producers after growth in the presence of soybean oil. Sequencing of 16S rRNA gene classified most isolates into the genus Marinobacter. The produced emulsions were shown to be stable up to 30 months monitoring period, in the presence of 300 g/l NaCl, at 4 °C and after high temperature treatment (120 °C for 20 min). The partially purified compounds obtained after growth on soybean oil-based media exhibited low toxicity towards V. fischeri and high capability to disperse crude oil on synthetic marine water. To the best of our knowledge, stability characterization of bioemulsifiers/biosurfactants from the non-pathogenic marine bacterium Marinobacter has not been previously reported. The produced compounds were shown to have potential for different applications including the environmental sector. Indeed, their high stability in the presence of high salt concentration and low temperature, conditions characterizing the marine environment, the capability to disperse crude oil and the low ecotoxicity makes them interesting for the development of biodispersants to be used in combatting marine oil spills.

The mental health of the UK Armed Forces: where facts meet fiction

Hunt, Elizabeth J. F.; Wessely, Simon; Jones, Norman; Rona, Roberto J.; Greenberg, Neil

2014-01-01

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

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

Jansen, Kathrin U; Anderson, Annaliesa S

2018-05-22

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

Understanding the role of spirituality as a potential coping mechanism for military personnel is important given growing concern about the mental health issues of personnel returning from war. This study seeks to determine the extent to which spirituality is associated with selected mental health problems among active duty military personnel and whether it moderates the relationship between combat exposure/deployment and (a) depression, (b) posttraumatic stress disorder (PTSD), and (c) suicidality in active duty military personnel. Data were drawn from the 2008 Department of Defense Survey of Health Related Behaviors Among Active Duty Military Personnel. Over 24,000 randomly selected active duty personnel worldwide completed an anonymous self-report questionnaire. High spirituality had a significant protective effect only for depression symptoms. Medium, as opposed to high or low, levels of spirituality buffered each of the mental health outcomes to some degree. Medium and low spirituality levels predicted depression symptoms but only among those with moderate combat exposure. Medium spirituality levels also predicted PTSD symptoms among those with moderate levels of combat exposure and predicted self-reported suicidal ideation/attempt among those never deployed. These results point to the complex relationship between spirituality and mental health, particularly among military personnel and the need for further research.

Can mental health and readjustment be improved in UK military personnel by a brief period of structured postdeployment rest (third location decompression)?

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

Obesity has become a major public health problem in the Arab countries, creating a health and economic burden on these countries' government services. There is an urgent need to develop a strategy for prevention and control of obesity. The third Arab Conference on Obesity and Physical Activity was held in Bahrain in January 2010, and proposed the Strategy to Combat Obesity and Promote Physical Activity in Arab Countries. This strategy provides useful guidelines for each Arab country to prepare its own strategy or plan of action to prevent and control obesity. The strategy focused on expected outcomes, objectives, indicators to measure the objectives, and action needs for 9 target areas: child-care centers for preschool children, schools, primary health care, secondary care, food companies, food preparation institutes, media, public benefit organizations, and the workplace. Follow-up and future developments of this strategy were also included.

Phage display creates innovative applications to combat hepatitis B virus

PubMed Central

Tan, Wen Siang; Ho, Kok Lian

2014-01-01

Hepatitis B virus (HBV) has killed countless lives in human history. The invention of HBV vaccines in the 20th century has reduced significantly the rate of the viral infection. However, currently there is no effective treatment for chronic HBV carriers. Newly emerging vaccine escape mutants and drug resistant strains have complicated the viral eradication program. The entire world is now facing a new threat of HBV and human immunodeficiency virus co-infection. Could phage display provide solutions to these life-threatening problems? This article reviews critically and comprehensively the innovative and potential applications of phage display in the development of vaccines, therapeutic agents, diagnostic reagents, as well as gene and drug delivery systems to combat HBV. The application of phage display in epitope mapping of HBV antigens is also discussed in detail. Although this review mainly focuses on HBV, the innovative applications of phage display could also be extended to other infectious diseases. PMID:25206271

Combating Memory Corruption Attacks On Scada Devices

NASA Astrophysics Data System (ADS)

Bellettini, Carlo; Rrushi, Julian

Memory corruption attacks on SCADA devices can cause significant disruptions to control systems and the industrial processes they operate. However, despite the presence of numerous memory corruption vulnerabilities, few, if any, techniques have been proposed for addressing the vulnerabilities or for combating memory corruption attacks. This paper describes a technique for defending against memory corruption attacks by enforcing logical boundaries between potentially hostile data and safe data in protected processes. The technique encrypts all input data using random keys; the encrypted data is stored in main memory and is decrypted according to the principle of least privilege just before it is processed by the CPU. The defensive technique affects the precision with which attackers can corrupt control data and pure data, protecting against code injection and arc injection attacks, and alleviating problems posed by the incomparability of mitigation techniques. An experimental evaluation involving the popular Modbus protocol demonstrates the feasibility and efficiency of the defensive technique.

The problem of obesity and dietary nudges.

2018-01-01

From a psychological perspective, Cass R. Sunstein's 2016 book The Ethics of Influence is an insightful examination of the ethics of using social and cognitive psychological principles to influence behavior and decision-making. The United States has been experiencing what can only be described as an obesity epidemic. Scientists know that this epidemic has been brought about in part by the prevailing choice architecture, which influences what we eat, how much we eat, and how little we exercise. From a public health perspective, the policy issue centers on how a democracy can employ a combination of bans, mandates, and nudges to reshape our dietary habits to combat obesity. In this article, I will address how policymakers must nudge and change the existing psychological and physical choice architecture to combat obesity. The obesity epidemic cannot be won solely by increasing taxes, mandates, and bans on certain food items as that infringes on the personal liberty, welfare, autonomy, and dignity of citizens.

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

Cyber Friendly Fire: Research Challenges for Security Informatics

This paper addresses cognitive implications and research needs surrounding the problem of cyber friendly fire (FF). We define cyber FF as intentional offensive or defensive cyber/electronic actions intended to protect cyber systems against enemy forces or to attack enemy cyber systems, which unintention-ally harms the mission effectiveness of friendly or neutral forces. Just as with combat friendly fire, maintaining situation awareness (SA) is paramount to avoiding cyber FF incidents. Cyber SA concerns knowledge of a system’s topology (connectedness and relationships of the nodes in a system), and critical knowledge elements such as the characteristics and vulnerabilities of the components thatmore » comprise the system and its nodes, the nature of the activities or work performed, and the available defensive and offensive countermeasures that may be applied to thwart network attacks. Mitigation strategies to combat cyber FF— including both training concepts and suggestions for decision aids and visualization approaches—are discussed.« less

Merz, A. W.; Hague, D. S.

1977-01-01

A reduced-order version of the one-on-one aerial combat problem is studied as a pursuit-evasion differential game. The coplanar motion takes place at given speeds and given maximum available turn rates, and is described by three state equations which are equivalent to the range, bearing, and heading of one aircraft relative to the other. The purpose of the study is to determine those relative geometries from which either aircraft can be guaranteed a win, regardless of the maneuver strategies of the other. Termination is specified by the tail-chase geometry, at which time the roles of pursuer and evader are known. The roles are found in general, together with the associated optimal turn maneuvers, by solution of the differential game of kind. For the numerical parameters chosen, neither aircraft can win from the majority of possible initial conditions if the other turns optimally in certain critical geometries.

Application of Nanoparticle Technologies in the Combat against Anti-Microbial Resistance.

PubMed

Kumar, Mayur; Curtis, Anthony; Hoskins, Clare

2018-01-14

Anti-microbial resistance is a growing problem that has impacted the world and brought about the beginning of the end for the old generation of antibiotics. Increasingly, more antibiotics are being prescribed unnecessarily and this reckless practice has resulted in increased resistance towards these drugs, rendering them useless against infection. Nanotechnology presents a potential answer to anti-microbial resistance, which could stimulate innovation and create a new generation of antibiotic treatments for future medicines. Preserving existing antibiotic activity through novel formulation into or onto nanotechnologies can increase clinical longevity of action against infection. Additionally, the unique physiochemical properties of nanoparticles can provide new anti-bacterial modes of action which can also be explored. Simply concentrating on antibiotic prescribing habits will not resolve the issue but rather mitigate it. Thus, new scientific approaches through the development of novel antibiotics and formulations is required in order to employ a new generation of therapies to combat anti-microbial resistance.

Broad Specificity Efflux pumps and Their Role in Multidrug Resistance of Gram Negative Bacteria

PubMed Central

Nikaido, Hiroshi; Pagès, Jean-Marie

2013-01-01

Antibiotic resistance mechanisms reported in Gram-negative bacteria are producing a worldwide health problem. The continuous dissemination of «multi-drug resistant» (MDR) bacteria drastically reduces the efficacy of our antibiotic “arsenal” and consequently increases the frequency of therapeutic failure. In MDR bacteria, the over-expression of efflux pumps that expel structurally-unrelated drugs contributes to the reduced susceptibility by decreasing the intracellular concentration of antibiotics. During the last decade, several clinical data indicate an increasing involvement of efflux pumps in the emergence and dissemination of resistant Gram-negative bacteria. It is necessary to clearly define the molecular, functional and genetic bases of the efflux pump in order to understand the translocation of antibiotic molecules through the efflux transporter. The recent investigation on the efflux pump AcrB at its structural and physiological level, including the identification of drug affinity sites and kinetic parameters for various antibiotics, may open the way to rationally develop an improved new generation of antibacterial agents as well as efflux inhibitors in order to efficiently combat efflux-based resistance mechanisms.

This paper addresses the health problems and opportunities that society will face in 2030. We propose a proactive model to combat the trend towards declining levels of physical activity and increasing obesity. The model emphasizes the need to increase physical activity among individuals of all ages. We focus on the right to move and the benefits of physical activity. The paper introduces a seven-level model that includes cells, creature (individual), clan (family), community, corporation, country, and culture. At each level the model delineates how increased or decreased physical activity influences health and well-being across the life span. It emphasizes the importance of combining multiple disciplines and corporate partners to produce a multifaceted cost-effective program that increases physical activity at all levels. The goal of this paper is to recognize exercise as a powerful, low-cost solution with positive benefits to cognitive, emotional, and physical health. Further, the model proposes that people of all ages should incorporate the “right to move” into their life style, thereby maximizing the potential to maintain health and well-being in a cost-effective, optimally influential manner.

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.

ADRPM-VII applied to the long-range acoustic detection problem

NASA Technical Reports Server (NTRS)

Shalis, Edward; Koenig, Gerald

1990-01-01

An acoustic detection range prediction model (ADRPM-VII) has been written for IBM PC/AT machines running on the MS-DOS operating system. The software allows the user to predict detection distances of ground combat vehicles and their associated targets when they are involved in quasi-military settings. The program can also calculate individual attenuation losses due to spherical spreading, atmospheric absorption, ground reflection and atmospheric refraction due to temperature and wind gradients while varying parameters effecting the source-receiver problem. The purpose here is to examine the strengths and limitations of ADRPM-VII by modeling the losses due to atmospheric refraction and ground absorption, commonly known as excess attenuation, when applied to the long range detection problem for distances greater than 3 kilometers.

Biosynthesis of the acetyl‐CoA carboxylase‐inhibiting antibiotic, andrimid in Serratia is regulated by Hfq and the LysR‐type transcriptional regulator, AdmX

Nogellova, Veronika; Morel, Bertrand; Krell, Tino

2016-01-01

Summary Infections due to multidrug‐resistant bacteria represent a major global health challenge. To combat this problem, new antibiotics are urgently needed and some plant‐associated bacteria are a promising source. The rhizobacterium Serratia plymuthica A153 produces several bioactive secondary metabolites, including the anti‐oomycete and antifungal haterumalide, oocydin A and the broad spectrum polyamine antibiotic, zeamine. In this study, we show that A153 produces a second broad spectrum antibiotic, andrimid. Using genome sequencing, comparative genomics and mutagenesis, we defined new genes involved in andrimid (adm) biosynthesis. Both the expression of the adm gene cluster and regulation of andrimid synthesis were investigated. The biosynthetic cluster is operonic and its expression is modulated by various environmental cues, including temperature and carbon source. Analysis of the genome context of the adm operon revealed a gene encoding a predicted LysR‐type regulator, AdmX, apparently unique to Serratia strains. Mutagenesis and gene expression assays demonstrated that AdmX is a transcriptional activator of the adm gene cluster. At the post‐transcriptional level, the expression of the adm cluster is positively regulated by the RNA chaperone, Hfq, in an RpoS‐independent manner. Our results highlight the complexity of andrimid biosynthesis – an antibiotic with potential clinical and agricultural utility. PMID:26914969

2017-10-01

The present study described the types and amount of problems and services sought among returned deployed Army National Guard soldiers (4568 soldiers in 50 units). The study responds to gaps in the research literature to better understand community intervention needs of reservists. About half (48%) of the soldiers reported one or two problems, mostly those of psychological well-being, such as feelings of anger and frustration, upsetting memories, and troubled sleep (34% of the study sample), followed by problems of social support (18%), alcohol use (17%), feelings of isolation including suicidal thoughts (13%), and financial difficulties (11%). Having engaged in direct combat and having wounded or killed someone showed positive relationships with reported problems. One-third (35%) of soldiers who reported having used services went to one service and, generally, soldiers went to services related to their expressed problems. Variance in self-reported problems explained by service use was low, suggesting unsought postdeployment services.

2011-01-01

Human stem cell-based therapeutic intervention strategies for treating HIV infection have recently undergone a renaissance as a major focus of investigation. Unlike most conventional antiviral therapies, genetically engineered hematopoietic stem cells possess the capacity for prolonged self-renewal that would continuously produce protected immune cells to fight against HIV. A successful strategy therefore has the potential to stably control and ultimately eradicate HIV from patients by a single or minimal treatment. Recent progress in the development of new technologies and clinical trials sets the stage for the current generation of gene therapy approaches to combat HIV infection. In this review, we will discuss two major approaches that are currently underway in the development of stem cell-based gene therapy to target HIV: One that focuses on the protection of cells from productive infection with HIV, and the other that focuses on targeting immune cells to directly combat HIV infection.

2017-01-01

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

A formulation and analysis of combat games

NASA Technical Reports Server (NTRS)

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

1985-01-01

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

In today's Electronic equipment manufacturing, managing an ESD (Electro static Discharge) plan is an integral part of a complete quality program. Every body has been in presence of static electricity one day or an other. But a discharge on a body of man is only felt when the potential of charge before the discharge is higher than 3000 volts but components can have a sensitivity less than 20 Volts !

30 years have passed since Conference of Experts on the Rational Use of Drugs was held in Nairobi, Kenya, from 25 to 29 November 1985, where the problem of counterfeit medicines was mentioned as the international for the first time. The problem of counterfeit medicines is not only a major threat to public health and national and private economy, but also it is of great interest for key decision-making actors at the international level. The authors analyzed what has been done since that time by international organizations. Combating the counterfeiting of medicines cannot be successfully achieved by the health sector alone - World Health Organization (WHO), - so the efforts of the other United Nations (UN) organizations relevant to counterfeiting were in need and were studied in the article: World Intellectual Property Organization (WIPO), World Trade Organization (WTO), World Customs Organization (WCO), United Nations Office on Drugs and Crime (UNODC), etc. Today WHO is unable to coordinate all their activities, so the few existing proposals for establishing a new mechanism of international cooperation have been examined. Will the MEDICRIME Convention that will enter into force on January 1, 2016 be the start of the new era in the combating with the counterfeit medicines? - the authors offered their vision on the international developments.

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

Janes, G R; Goldberg, J; Eisen, S A; True, W R

1991-01-01

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

The role of international travel in the worldwide spread of multiresistant Enterobacteriaceae.

PubMed

2012-09-01

From international tourists to war-displaced refugees, more people are on the move than ever before. This provides the opportunity for a variety of antimicrobial-resistant bacteria to be carried from one geographic location to another. The Enterobacteriaceae are among the most important causes of serious hospital-acquired and community-onset bacterial infections in humans, and resistance to antimicrobial agents in these bacteria has become an increasingly relevant problem. International travel and tourism are important modes for the acquisition and spread of antimicrobial-resistant Enterobacteriaceae, especially CTX-M-producing Escherichia coli. Infections with KPC-, VIM-, OXA-48- and NDM-producing Enterobacteriaceae in developed countries have been associated with visiting and being hospitalized in endemic areas such as the USA, Greece and Israel for KPCs, Greece for VIMs, Turkey for OXA-48, and the Indian subcontinent for NDMs. To combat the spread of antimicrobial-resistant Enterobacteriaceae, the French Healthcare Safety Advisory Committee recently issued national recommendations for screening and contact isolation precautions for patients transferred from, or hospitalized outside, France. For effective public and patient health interventions, it is important to understand the role of international travel in the spread of antimicrobial-resistant Enterobacteriaceae. We urgently need well-designed studies to evaluate the transmission potential and risks for colonization and infections due to multiresistant Enterobacteriaceae in travellers who have recently visited or have been hospitalized in endemic areas. The emergence of CTX-M-, KPC- and NDM-producing bacteria is a good example of the role that globalization plays in the rapid dissemination of new antibiotic resistance mechanisms.

Sleep quality affects cognitive functioning in returning combat veterans beyond combat exposure, PTSD, and mild TBI history.

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

A formulation and analysis of combat games

NASA Technical Reports Server (NTRS)

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

1984-01-01

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

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

2011-12-01

Despite well-documented postdeployment readjustment problems affecting veterans of Operations Enduring Freedom (OEF) and Iraqi Freedom (OIF), few studies have explored the possible relationship of readjustment stressors to the recent increase in military suicide. This study examined associations between suicidal ideation and postdeployment readjustment problems using cross-sectional population-based survey data from 1665 National Guard members who recently returned from Iraq. The findings suggested that readjustment problems are widespread, with 45% of veterans endorsing one or more financial or family problems 3 months postdeployment. After adjusting for mental health and combat exposure, veterans with the highest number of readjustment stressors were at 5½ times greater risk of suicidal ideation than those with no stressors. In a psychiatrically impaired subsample, the high stressor group experienced a fourfold risk of suicide ideation compared with those with no stressors. The findings argue for suicide prevention efforts that more directly target readjustment problems in returning OEF/OIF veterans.

War wounds produce a significant burden on medical facilities in wartime. Workload from the recent conflict was documented in order to guide future medical needs. All data on war injuries were collected prospectively. This information was supplemented with a review of all patients admitted during the study period. During the first 2 weeks of the conflict, the sole British field hospital in the region received 482 casualties. One hundred and four were battle injuries of which nine were burns. Seventy-nine casualties had their initial surgery performed by British military surgeons and form the study group. Twenty-nine casualties (37 per cent) sustained gunshot wounds, 49 (62 per cent) suffered wounds from fragmentation weapons and one casualty detonated an antipersonnel mine. These 79 patients had a total of 123 wounds that were scored prospectively using the Red Cross Wound Classification. Twenty-seven (34 per cent) of the wounded were non-combatants; eight of these were children. Four patients (5 per cent) died. War is changing; modern conflicts appear likely to be fought in urban or remote environments, producing different wounding patterns and placing non-combatants in the line of fire. Military medical skills training and available resources must reflect these fundamental changes in preparation for future conflicts.

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

The involvement of anger in the psychological adjustment of current war veterans, particularly in conjunction with combat-related posttraumatic stress disorder (PTSD), warrants greater research focus than it has received. The present study concerns a brief anger measure, Dimensions of Anger Reactions (DAR), intended for use in large sample studies and as a screening tool. The concurrent validity, discriminant validity, and incremental validity of the instrument were examined in conjunction with behavioral health data for 3,528 treatment-seeking soldiers who had been in combat in Iraq and Afghanistan. Criterion indices included multiple self-rated measures of psychological distress (including PTSD, depression, and anxiety), functional difficulties (relationships, daily activities, work problems, and substance use), and violence risk. Concurrent validity was established by strong correlations with single anger items on 4 other scales, and discriminant validity was found against anxiety and depression measures. Pertinent to the construct of anger, the DAR was significantly associated with psychosocial functional difficulties and with several indices of harm to self and to others. Hierarchical regression performed on a self/others harm index found incremental validity for the DAR, controlling for age, education, military component, officer rank, combat exposure, PTSD, and depression. The ability to efficiently assess anger in at-risk military populations can provide an indicator of many undesirable behavioral health outcomes.

Health hazards in areas of military operations conducted in different climatic and sanitary conditions.

PubMed

Korzeniewski, Krzysztof

2011-01-01

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

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

PubMed

Stein, Herbert H

2007-01-01

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

The government of Indonesia has taken steps to foster economic growth in the eastern region of the country by creating a transportation infrastructure. While many parts of the region still lack sea transportation, the rate of economic growth in the region has outstripped that of the nation since 1993. In this region, clove was the major cash crop, but trade regulations have reduced the profit in clove farming. Maluku was once renowned for its fishing, but this industry is now dominated by big investors, and the region depends upon aid for backward villages and upon loans from nongovernmental organizations (NGOs) that are funneled through local self-help groups. The Yayasan Indonesia Sejahtera (YIS) has worked in eastern Indonesia since 1974 and is planning to collect data on its most urgent problems and to fund the income-generation project proposals submitted by NGOs. Among these programs are foundations that provide funds for fishermen to purchase motorized boats, loans to groups of traders, and loans for fishermen and for breeding goats and chickens. Women can also procure loans to sell groceries or for farming activities. The self-help groups of fishermen face obstacles when the weather prohibits fishing, and the farmers have problems obtaining good breeders and combating disease among their livestock. The NGOs combat problems caused by a lack of field workers and by limited funds as well as the obstacles caused by the geography of the region. Members of the self-help groups are improving their knowledge and skills, and the NGOs are improving their management capabilities to deal with these challenges.

In this study, we examined the relationship between depression and HIV-related risk behavior practices in a sample of 250 at risk, predominantly African American women living in the Atlanta, Georgia metropolitan area. Interviews were conducted between August 1997 and August 2000. Street outreach efforts were used to identify potential study participants, with further expansion of the sample via targeted sampling and ethnographic mapping procedures. Our conceptual model hypothesized a relationship between depression and HIV risk in which depression and condom-related attitudes were construed as intervening (or mediating) variables. A multivariate analysis was used to determine the relationship between depression and women's risk behaviors. The results showed that depression was a key-mediating variable, having its primary influence on women's risky practices through its impact upon their attitudes toward using condoms. Factors associated with depression, included religiosity, closeness of family relationships, financial problems, childhood maltreatment experiences, and drug-related problems. The implications of these findings for prevention and intervention efforts are: (1) heightening faith community involvement and religious participation to decrease depression; (2) working with women whose familial bonds are in need of strengthening to combat depression; (3) providing mental health and counseling services to women who were emotionally and/or sexually abused during their formative years seems to help these women to recover from unresolved issues that may be fueling depression; (4) assisting at risk women who need training in money management issues to minimize their risk for depression; and (5) helping women drug abusers to receive treatment for their drug problems to combat their depression and lower their HIV risk.

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

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

In contrast to previous research that has primarily examined how psychological disorders (e.g., post-traumatic stress disorder [PTSD], anxiety) are affected by and affect individuals' threat perceptions, this study examines the relationship between combat experience and threat-monitoring in psychologically healthy Soldiers. Existing research has established how prolonged or intense experiences with war-related stressors can lead individuals to undergo an unconscious fear-conditioning process that affects the circuitry of the prefrontal cortex, hippocampus, amygdala, and anterior cingulate cortex regions of the brain. We predict that the intensity of one's combat experience positively influences Soldiers' attention to environmental threats. Participants included U. S. Army Soldiers with a score of 50 or below on the PTSD Checklist-Military Version. Participants completed the Combat Exposure Scale and the State-Trait Anxiety Inventory. The experimental prediction task we employed assesses the expectation of an intrusively loud white noise sound that occurred on three variable patterns in a pseudorandomized order. Each tone pattern was used 20 times over a total of 60 trials. The experimental prediction task included two neutral tones (700 and 1,300 Hz) that were presented in a repeated pattern along with a 100-dB burst of white noise (0.5-second duration). In each trial, one of three possible tone combinations was presented. To assess their attentiveness to threats, participants were asked to continuously rate their expectancy of the burst of white noise using a visual analogue scale (VAS) ranging from 0 to 100. VAS ratings were collected at controlled points throughout the task. None of the participants reported scores on any of the diagnostic surveys that met standards for clinical significance. A repeated-measures analysis of variance was conducted to assess the overall effect of the three prediction conditions on participants' VAS ratings. There was a significant main effect for Combat Exposure Scale scores on VAS ratings [F (1, 27) = 5.19, p = 0.031], with high scorers demonstrating a generally higher expectancy of the white noise burst throughout the entire experimental sequence. Results suggest that within subclinical populations of Soldiers, the intensity of one's combat experience is positively associated with their attention to threats. These findings suggest that Soldiers who experience combat should be observed for signs of increased threat-attention bias, as this may indicate that their capacities for information processing, decision-making, and emotion regulation could be compromised. The positive relationship we observe between a level of combat experience and attentional biases toward threatening stimuli may also help to explain why these veterans engage in "externalizing" behaviors that are risky, aggressive, or violent as well as relational problems and antisocial behaviors that are reported in higher-than-average rates among these populations of Soldiers. Acknowledging that increased threat attention may be a preclinical indication of developing PTSD or other related psychological conditions (e.g., depression, anxiety) should motivate clinicians to more actively diagnose and treat this condition.

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

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

Modeling the Effects of Stress: An Approach to Training

NASA Technical Reports Server (NTRS)

Cuper, Taryn

2010-01-01

Stress is an integral element of the operational conditions experienced by combat medics. The effects of stress can compromise the performance of combat medics who must reach and treat their comrades under often threatening circumstances. Examples of these effects include tunnel vision, loss of motor control, and diminished hearing, which can result in an inability to perceive further danger, satisfactorily treat the casualty, and communicate with others. While many training programs strive to recreate this stress to aid in the experiential learning process, stress inducement may not always be feasible or desired. In addition, live simulations are not always a practical, convenient, and repeatable method of training. Instead, presenting situational training on a personal computer is proposed as an effective training platform in which the effects of stress can be addressed in a different way. We explore the cognitive and motor effects of stress, as well as the benefits of training for mitigating these effects in real life. While many training applications focus on inducing stress in order to "condition" the stress response, the author explores the possibilities of modeling stress to produce a similar effect. Can presenting modeled effects of stress help prepare or inoculate soldiers for stressful situations in which they must perform at a high level? This paper investigates feasibility of modeling stress and describes the preliminary design considerations of a combat medic training system that utilizes this method of battlefield preparation.

Managed access technology to combat contraband cell phones in prison: Findings from a process evaluation.

2018-02-01

Cell phones in correctional facilities have emerged as one of the most pervasive forms of modern contraband. This issue has been identified as a top priority for many correctional administrators in the United States. Managed access, a technology that utilizes cellular signals to capture transmissions from contraband phones, has received notable attention as a promising tool to combat this problem. However, this technology has received little evaluative attention. The present study offers a foundational process evaluation and draws upon output measures and stakeholder interviews to identify salient operational challenges and subsequent lessons learned about implementing and maintaining a managed access system. Findings suggest that while managed access captures large volumes of contraband cellular transmissions, the technology requires significant implementation planning, personnel support, and complex partnerships with commercial cellular carriers. Lessons learned provide guidance for practitioners to navigate these challenges and for scholars to improve future evaluations of managed access. Copyright © 2017 Elsevier Ltd. All rights reserved.

Application of Nanoparticle Technologies in the Combat against Anti-Microbial Resistance

PubMed Central

Kumar, Mayur; Curtis, Anthony

2018-01-01

Anti-microbial resistance is a growing problem that has impacted the world and brought about the beginning of the end for the old generation of antibiotics. Increasingly, more antibiotics are being prescribed unnecessarily and this reckless practice has resulted in increased resistance towards these drugs, rendering them useless against infection. Nanotechnology presents a potential answer to anti-microbial resistance, which could stimulate innovation and create a new generation of antibiotic treatments for future medicines. Preserving existing antibiotic activity through novel formulation into or onto nanotechnologies can increase clinical longevity of action against infection. Additionally, the unique physiochemical properties of nanoparticles can provide new anti-bacterial modes of action which can also be explored. Simply concentrating on antibiotic prescribing habits will not resolve the issue but rather mitigate it. Thus, new scientific approaches through the development of novel antibiotics and formulations is required in order to employ a new generation of therapies to combat anti-microbial resistance.

Near-Nash targeting strategies for heterogeneous teams of autonomous combat vehicles

NASA Astrophysics Data System (ADS)

Galati, David G.; Simaan, Marwan A.

2008-04-01

Military strategists are currently seeking methodologies to control large numbers of autonomous assets. Automated planners based upon the Nash equilibrium concept in non-zero sum games are one option. Because such planners inherently consider possible adversarial actions, assets are able to adapt to, and to some extent predict, potential enemy actions. However, these planners must function properly both in cases in which a pure Nash strategy does not exist and in scenarios possessing multiple Nash equilibria. Another issue that needs to be overcome is the scalability of the Nash equilibrium. That is, as the dimensionality of the problem increases, the Nash strategies become unfeasible to compute using traditional methodologies. In this paper we introduce the concept of near-Nash strategies as a mechanism to overcome these difficulties. We then illustrate this concept by deriving the near-Nash strategies and using these strategies as the basis for an intelligent battle plan for heterogeneous teams of autonomous combat air vehicles in the Multi-Team Dynamic Weapon Target Assignment model.

On Aug. 25, 1980, without warning, a large oil slick invaded the north and west coasts of Bahrain. This serious incident was designated a national emergency, and a special high-level government committee was established immediately to handle the response procedure. This paper describes how the committee functioned with the private sector and the problems encountered and overcome. The lessons learned have stimulated interest in the proposed use of computers to aid combat operations as both a technical tool and an information service. In addition, this experience can guide those responsible for controlling response operations for future major oil spills inmore » coastal areas. With proper planning, a highly satisfactory cooperative organization can be established between goverment and the private sector to respond effectively, economically, and with minimum environmental damage to a major oil spill affecting coastal waters and shorelines. Part of this planning is to collate and record the major available response equipment and material packages, thereby increasing the necessary state of readiness.« less

The toll of multiple and prolonged deployments on families has become clearer in recent years as military families have seen an increase in childhood anxiety, parental psychological distress, and marital discord. Families overcoming under stress (FOCUS), a family-centered evidence-informed resiliency training program developed at University of California, Los Angeles and Harvard Medical School, is being implemented at military installations through an initiative from Navy Bureau of Medicine and Surgery. The research foundation for FOCUS includes evidence-based preventive interventions that were adapted to meet the specific needs of military families facing combat operational stress associated with wartime deployments. Using a family narrative approach, FOCUS includes a customized approach utilizing core intervention components, including psychoeducation, emotional regulation skills, goal setting and problem solving skills, traumatic stress reminder management techniques, and family communication skills. The purpose of this study is to describe the development and implementation of FOCUS for military families. A case example is also presented.
