A comparison between sudden cardiac arrest on military bases and non-military settings.

INTRODUCTION: Out-of-hospital cardiac arrests contribute to significant morbidity and mortality in both non-military/civilian and military populations. Early CPR and AED use have been linked with improved outcomes. There is public health interest in identifying communities with high rates of both with the hopes of creating generalizable tactics for improving cardiac arrest survival. METHODS: We examined a national registry of EMS activations in the United States (NEMSIS). Inclusion criteria were witnessed cardiac arrests from January 2020 to September 2022 where EMS providers documented the location of the arrest, whether CPR was provided prior to their arrival (yes/no), and whether an AED was applied prior to their arrival (yes/no). Cardiac arrests were then classified as occurring on a military base or in a non-military setting. RESULTS: A total of 60 witnessed cardiac arrests on military bases and 202,605 witnessed cardiac arrests in non-military settings met inclusion criteria. Importantly, the prevalence of CPR and AED use prior to EMS arrival was significantly higher on military bases compared to non-military settings. CONCLUSIONS: Reasons for the trends we observed may be a greater availability of CPR-trained individuals and AEDs on military bases, as well as a widespread willingness to provide aid to victims of cardiac arrest. Further research should examine cardiac arrests on military bases.

Characterization of Humanitarian Trauma Care by US Military Facilities During Combat Operations in Afghanistan and Iraq.

OBJECTIVE: To characterize humanitarian trauma care delivered by US military treatment facilities (MTFs) in Afghanistan and Iraq during combat operations. BACKGROUND: International Humanitarian Law, which includes the Geneva Conventions, defines protections and standards of treatment to victims of armed conflicts. In 1949, these standards expanded to include injured civilians. In 2001, the Global War on Terror began in Afghanistan and expanded to Iraq in 2003. US MTFs provided care to all military forces, civilians, and enemy prisoners. A thorough understanding of the scope, epidemiology, resource requirements, and outcomes of civilian trauma in combat zones has not been previously characterized. METHODS: Retrospective cohort analysis of the Department of Defense Trauma Registry from 2005 to 2019. Inclusion criteria were civilians and Non-North Atlantic Treaty Organization (NATO) Coalition Personnel (NNCP) with traumatic injuries treated at MTFs in Afghanistan and Iraq. Patient demographics, mechanism of injury, resource requirements, procedures, and outcomes were categorized. RESULTS: A total of 29,963 casualties were eligible from the Registry. There were 16,749 (55.9%) civilians and 13,214 (44.1%) NNCP. The majority of patients were age above 13 years [26,853 (89.6%)] and male [28,000 (93.4%)]. Most injuries were battle-related: 12,740 (76.1%) civilians and 11,099 (84.0%) NNCP. Penetrating trauma was the most common cause of both battle and nonbattle injuries: 12,293 (73.4%) civilian and 10,029 (75.9%) NNCP. Median Injury Severity Score (ISS) was 9 in each cohort with ISS≥25 in 2236 (13.4%) civilians and 1398 (10.6%) NNCP. Blood products were transfused to 35% of each cohort: 5850 civilians received a transfusion with 2118 (12.6%) of them receiving ≥10 units; 4590 NNCPs received a transfusion with 1669 (12.6%) receiving ≥10 units. MTF mortality rates were civilians 1263 (7.5%) and NNCP 776 (5.9%). Interventions, both operative and nonoperative, were similar between both groups. CONCLUSIONS: In accordance with International Humanitarian Law, as well as the US military's medical rules of eligibility, civilians injured in combat zones were provided the same level of care as NNCP. Injured civilians and NNCP had similar mechanisms of injury, injury patterns, transfusion needs, and ISS. This analysis demonstrates resource equipoise in trauma care delivered to civilians and NNCP. Hospitals in combat zones must be prepared to manage large numbers of civilian casualties with significant human and material resources allocated to optimize survival. The provision of humanitarian trauma care is resource-intensive, and these data can be used to inform planning factors for current or future humanitarian care in combat zones.

Lessons from outbreaks of COVID-19 at Israeli military bases.

BACKGROUND: To mitigate the spread of coronavirus disease 2019 (COVID-19), national guidelines, in accordance with international health authorities, mandated 14 days of quarantine for every close contact of a confirmed COVID-19 patient. Although health benefits are obvious, consequences are profound, especially for organizations required to maintain operational preparedness. OBJECTIVES: To present the Israel Defense Force (IDF) experience with outbreaks regarding quarantined individuals. To weigh the consequences of quarantined individuals needed for workforce and operation. METHODS: All positive COVID-19 cases in the IDF, as measured by a positive rRT-PCR test result, between 29 February and 18 May 2020 were evaluated. Numbers of positive individuals, quarantined individuals, and confirmatory exams conducted were collected. We compared the events in four units with the largest outbreaks and assessed the impact of confirmed cases, tests conducted, and workforce loss due to quarantine. RESULTS: Of the 187 soldiers who tested positive for COVID-19, source of infection was traced to 140 soldiers (75%). Almost no medical treatment was delivered, and hospitalization was rare. We found a median of 15.2% (interquartile range 5.3-34) for decline in unit workforce due to quarantine measures. Maximum reduction reached 47% of the workforce in one unit. CONCLUSIONS: Despite a relatively small number of confirmed cases, units underwent a substantial change in mode of operation due to the toll of quarantined individuals. In certain populations and organizations, perhaps a more liberal application of isolation and contact tracing is suitable due to the heavy economic burden and consequences in term of operational readiness.

Comparison of Estrogenic, Spectroscopic, and Toxicological Analyses of Pilot-Scale Water, Wastewaters, and Processed Wastewaters at Select Military Installations.

Reuse of water requires the removal of contaminants to ensure human health. We report the relative estrogenic activity (REA) of reuse treatment design scenarios for water, wastewaters, and processed wastewaters before and after pilot-scale treatment systems tested at select military facilities. The comparative relationships between REA, several composite toxicological endpoints, and spectroscopic indicators were evaluated for different reuse treatment trains. Four treatment processes including conventional and advanced treatments reduced the estrogenicity by at least 33%. Biologically based methods reduced estrogenicity to below detection levels. Conventional treatment scenarios led to significantly less reduction of adverse biological endpoints compared to the advanced treatment scenarios. Incorporating the anaerobic membrane bioreactor reduced more endpoints with higher reduction percentages compared to the sequencing batch reactor design. Membrane technology and advanced oxidation generated reductions across all biological endpoints, from 65% (genotoxicity) to 100% (estrogenicity). The design scenarios featuring a low-cutoff mechanical screen filter, intermittent activated carbon biofilter, and membrane filtration achieved the highest percent reduction and produced water with the lowest negative biological endpoints. Spectroscopic indicators demonstrated case-specific relationships with estrogenicity and toxicity. Estrogenicity consistently correlated with cytotoxicity and thiol reactivity, indicating the potential for preliminary estrogenicity screening using thiol reactivity.

[The contribution of teleconsultation and isolation of symptomatic cases in control of the COVID-19 outbreak a military base]. / Apport de la téléconsultation et de l'isolement des cas symptomatiques dans la maîtrise de l'épidémie COVID-19 au sein d'une base militaire.

BACKGROUND: The first wave of COVID-19 swept over France during the first quarter of 2020, leading to saturation of the health care system. We wished to study, in a French military medical unit assisting one of the country's largest armed forces populations, the impact of teleconsultation and the systematic isolation of all possible, probable and confirmed cases of COVID-19. METHODS: This is a retrospective study carried out from March 9 to May 31, 2020 on the basis of our activity register. The variables collected included type of medical consultation procedure, occupational status, classification of cases and date of onset of first symptoms. We have paralleled our activity with that of SOS Médecins and the emergency departments of the Île-de-France region. RESULTS/DISCUSSION: During this period, 1719 episodes of care (teleconsultations or physical consultations) were recorded, of which 91% (n=1561) were linked to COVID-19. We identified 598 "suspected" (possible and probable) and confirmed cases. "Isolated" teleconsultations (not followed by a face-to-face medical consultation, sample taking or necessitating the dispatch of prompt assistance) represented 86% of episodes of care (n=1482). Comparison of our activity and the number of new cases with the databases of SOS Médecins and the Île-de-France emergency services suggests that our isolation strategy was timely and effective. CONCLUSION: The contribution of teleconsultation was substantial and reassuring. Teleconsultation makes it possible to absorb a large volume of patients, is easy to implement, and entails no nosocomial risk. Isolation of infected patients should be a priority during an outbreak. Once it has become a priority to rapidly bring an epidemic under control, this attitude must be extended to all symptomatic patients.

An artificially simulated outbreak of a respiratory infectious disease.

BACKGROUND: Outbreaks of respiratory infectious diseases often occur in crowded places. To understand the pattern of spread of an outbreak of a respiratory infectious disease and provide a theoretical basis for targeted implementation of scientific prevention and control, we attempted to establish a stochastic model to simulate an outbreak of a respiratory infectious disease at a military camp. This model fits the general pattern of disease transmission and further enriches theories on the transmission dynamics of infectious diseases. METHODS: We established an enclosed system of 500 people exposed to adenovirus type 7 (ADV 7) in a military camp. During the infection period, the patients transmitted the virus randomly to susceptible people. The spread of the epidemic under militarized management mode was simulated using a computer model named "the random collision model", and the effects of factors such as the basic reproductive number (R0), time of isolation of the patients (TOI), interval between onset and isolation (IOI), and immunization rates (IR) on the developmental trend of the epidemic were quantitatively analysed. RESULTS: Once the R0 exceeded 1.5, the median attack rate increased sharply; when R0 = 3, with a delay in the TOI, the attack rate increased gradually and eventually remained stable. When the IOI exceeded 2.3 days, the median attack rate also increased dramatically. When the IR exceeded 0.5, the median attack rate approached zero. The median generation time was 8.26 days, (95% confidence interval [CI]: 7.84-8.69 days). The partial rank correlation coefficients between the attack rate of the epidemic and R0, TOI, IOI, and IR were 0.61, 0.17, 0.45, and - 0.27, respectively. CONCLUSIONS: The random collision model not only simulates how an epidemic spreads with superior precision but also allows greater flexibility in setting the activities of the exposure population and different types of infectious diseases, which is conducive to furthering exploration of the epidemiological characteristics of epidemic outbreaks.

SARS-CoV-2 diagnostic diary: from rumors to the first case. Early reports of molecular tests from the military research and diagnostic institute of Rio de Janeiro.

Corona virus disease (COVID-19) presents a serious threat to global health. A historical timeline of early molecular diagnostics from government alert (January 22) (D) was presented. After in silico analysis, Brazilian Army Institute of Biology (IBEx-RJ) tested samples in house using real-time reverse transcriptase polymerase chain reaction (RT-PCR) (fast mode) based on Centers for Disease Control and Prevention (CDC) recommendations. First cases from Brazil, Rio de Janeiro, IBEx, and diagnosis team were reported in D36, D44, D66, and D74 respectively. Therefore, after 1300 tests, we recommend N1/N2 primer sets (CDC) for preliminary and Charité protocol confirmation in case of positive results. Moreover, every professional should be tested before starting work, in addition to weekly tests for everyone involved.

Assisted phytostabilization of soil from a former military area with mineral amendments.

Due to the presence of toxic pollutants, soils in former military areas need remedial actions with environmentally friendly methods. Greenhouse experiments were conducted to investigate the aided phytostabilization of multi-heavy metals (HMs), i.e. Cd, Cr, Cu, Ni, Pb, Zn, in post-military soil by Festuca rubra and three mineral amendments (diatomite, dolomite and halloysite). The amendments were applied at 0 and 3.0% to each pot filled with 5 kg of polluted soil. After seven weeks of the phytostabilization, selected soil properties, biomass yield of F. rubra and immobilization of HMs by their accumulation in plant and redistribution among individual fractions in soil were determined. In addition, ecotoxicology parameters of non-amended and amended soil were established using Phytotoxkit (Sinapsis alba) and Ostracodtoxkit (Heterocypris incongruens) tests. The addition of halloysite significantly increased F. rubra biomass. Diatomite significantly increased both the Cd, Cu, Pb and Cr concentrations in the roots and the pH of the soil. The application of halloysite significantly decreased the Cd and Zn contents of the soil after the completion of the experiment. Dolomite and halloysite were more effective in HM immobilization in soil by decreasing their content in an exchangeable fraction than diatomite. These soil amendments significantly differentiated the length of S. alba roots and had a positive effect on the development of H. incongruens.

Availability, price and promotions for cigarettes and non-cigarette tobacco products: an observational comparison of US Air Force bases with nearby tobacco retailers, 2016.

INTRODUCTION: Active duty military personnel have higher cigarette and smokeless tobacco use rates than civilian populations. Although US Airmen (called Airmen regardless of gender or rank) are required to be tobacco-free during initial training, many resume use once this period ends, perhaps as a result of easy access to cheap tobacco products. METHODS: Between July and September 2016, we collected tobacco product, price and promotion information by visiting on-base (n=28) and off-base (n=80) tobacco retailers near the eight technical training bases where approximately 99% of Airmen attend training. We conducted mixed linear effects models to examine on-base versus off-base differences. RESULTS: Cigarette packs were 11%-12% cheaper at on-base retailers compared with off-base retailers. Newport Menthol and Marlboro Red cigarette packs were $0.87 and $0.80 lower on-base (p<0.001) while the cheapest pack available was $0.54 lower on-base (p<0.01). Copenhagen smokeless tobacco was also significantly cheaper on-base (B=-0.65, p<0.01). Interior price promotions were more common on-base. CONCLUSIONS: Retail stores located on Air Force bases sell cigarettes and smokeless tobacco products at prices well below those in nearby off-base retailers: the vast majority of these retailers feature interior price promotions for these products. Federal policies regulating prices of on-base tobacco sales, if implemented more effectively, have the potential to protect the health of Airmen by helping them remain tobacco-free after technical training.

Occupation, settlement, and the social determinants of health for West Bank Palestinians.

A contentious issue in the Israel-Palestine conflict is the ongoing construction of settlements in the occupied West Bank along with its related policies, both of which have had impacts on the lives of resident Palestinians. These impacts have been documented by various UN and non-governmental agencies yet have been insufficiently studied in the academic literature. This article aims to review the literature on the social determinants of health for West Bank Palestinians and understand how settlement construction and policy influence these determinants. To accomplish these aims, the article first includes an analysis of how military infrastructure, resource allocation, land appropriation and house demolition related to the settlements influence the lives of West Bank Palestinians. The article then proceeds to review available literature on the social determinants of health in the West Bank, most notably: access to healthcare, exposure to political violence, economic conditions and water contamination, with the goal of understanding how settlement-related policies are related to these social determinants of health.

Comparison of visual and automated Deki Reader interpretation of malaria rapid diagnostic tests in rural Tanzanian military health facilities.

BACKGROUND: Although microscopy is a standard diagnostic tool for malaria and the gold standard, it is infrequently used because of unavailability of laboratory facilities and the absence of skilled readers in poor resource settings. Malaria rapid diagnostic tests (RDT) are currently used instead of or as an adjunct to microscopy. However, at very low parasitaemia (usually < 100 asexual parasites/µl), the test line on malaria rapid diagnostic tests can be faint and consequently hard to visualize and this may potentially affect the interpretation of the test results. Fio Corporation (Canada), developed an automated RDT reader named Deki Reader™ for automatic analysis and interpretation of rapid diagnostic tests. This study aimed to compare visual assessment and automated Deki Reader evaluations to interpret malaria rapid diagnostic tests against microscopy. Unlike in the previous studies where expert laboratory technicians interpreted the test results visually and operated the device, in this study low cadre health care workers who have not attended any formal professional training in laboratory sciences were employed. METHODS: Finger prick blood from 1293 outpatients with fever was tested for malaria using RDT and Giemsa-stained microscopy for thick and thin blood smears. Blood samples for RDTs were processed according to manufacturers' instructions automated in the Deki Reader. Results of malaria diagnoses were compared between visual and the automated devise reading of RDT and microscopy. RESULTS: The sensitivity of malaria rapid diagnostic test results interpreted by the Deki Reader was 94.1% and that of visual interpretation was 93.9%. The specificity of malaria rapid diagnostic test results was 71.8% and that of human interpretation was 72.0%. The positive predictive value of malaria RDT results by the Deki Reader and visual interpretation was 75.8 and 75.4%, respectively, while the negative predictive values were 92.8 and 92.4%, respectively. The accuracy of RDT as interpreted by DR and visually was 82.6 and 82.1%, respectively. CONCLUSION: There was no significant difference in performance of RDTs interpreted by either automated DR or visually by unskilled health workers. However, despite the similarities in performance parameters, the device has proven useful because it provides stepwise guidance on processing RDT, data transfer and reporting.

An Outbreak of Microsporum canis infection at a military base associated with stray cat exposure and person-to-person transmission.

Tinea corporis caused by Microsporum canis is usually associated with exposure to animals, but outbreaks with anthropophilic transmission were described. A large outbreak in a military base was investigated. We investigated the outbreak's source and risk factors for infection in order to contain and eliminate it. All staff-members at the base were interviewed and examined. A case-control analysis of symptomatic patients was used to elucidate risk factors. Stray cats were captured and sampled. M. canis isolated from skin and fur specimens of patients and cats were genotyped by microsatellite sequencing. Fifty-three of 502 staff-members were symptomatic. Logistic regression showed risk associated with female gender, cat contact at base and performance of guarding duty. Multiple stray cats were found at the base. M. canis isolates from 4 cats and 4 patients had an identical genotype, while 2 patients had different genotypes. We describe the largest M. canis outbreak reported until now. Epidemiological and phylogenetic tools were used to investigate the source of the outbreak. Multiple exposures to stray cats caused infection of mainly young female soldiers performing guarding duty. Other persons were infected by person-to-person transmission. These findings aided in the termination of the outbreak.

Expression in grasses of multiple transgenes for degradation of munitions compounds on live-fire training ranges.

The deposition of toxic munitions compounds, such as hexahydro-1, 3, 5-trinitro-1, 3, 5-triazine (RDX), on soils around targets in live-fire training ranges is an important source of groundwater contamination. Plants take up RDX but do not significantly degrade it. Reported here is the transformation of two perennial grass species, switchgrass (Panicum virgatum) and creeping bentgrass (Agrostis stolonifera), with the genes for degradation of RDX. These species possess a number of agronomic traits making them well equipped for the uptake and removal of RDX from root zone leachates. Transformation vectors were constructed with xplA and xplB, which confer the ability to degrade RDX, and nfsI, which encodes a nitroreductase for the detoxification of the co-contaminating explosive 2, 4, 6-trinitrotoluene (TNT). The vectors were transformed into the grass species using Agrobacterium tumefaciens infection. All transformed grass lines showing high transgene expression levels removed significantly more RDX from hydroponic solutions and retained significantly less RDX in their leaf tissues than wild-type plants. Soil columns planted with the best-performing switchgrass line were able to prevent leaching of RDX through a 0.5-m root zone. These plants represent a promising plant biotechnology to sustainably remove RDX from training range soil, thus preventing contamination of groundwater.

US Air Force Behavioral Health Optimization Program: team members' satisfaction and barriers to care.

BACKGROUND: Research has shown significant contribution of integrated behavioural health care; however, less is known about the perceptions of primary care providers towards behavioural health professionals. OBJECTIVE: The current study examined barriers to care and satisfaction with integrated behavioural health care from the perspective of primary care team members. DESIGN: This study utilized archival data from 42 treatment facilities as part of ongoing program evaluation of the Air Force Medical Service's Behavioral Health Optimization Program. SETTING: This study was conducted in a large managed health care organization for active duty military and their families, with specific clinic settings that varied considerably in regards to geographic location, population diversity and size of patient empanelment. STUDY PARTICIPANTS: De-identified archival data on 534 primary care team members were examined. RESULTS: Team members at larger facilities rated access and acuity concerns as greater barriers than those from smaller facilities (t(533) = 2.57, P < 0.05). Primary Care Managers (PCMs) not only identified more barriers to integrated care (ß = -0.07, P < 0.01) but also found services more helpful to the primary care team (t(362.52) = 1.97, P = 0.05). Barriers to care negatively impacted perceived helpfulness of integrated care services for patients (ß = -0.12, P < 0.01) and team members, particularly among non-PCMs (ß = -0.11, P < 0.01). CONCLUSIONS: Findings highlight the potential benefits of targeted training that differs in facilities of larger empanelment and is mindful of team members' individual roles in a Patient Centered Medical Home. In particular, although generally few barriers were perceived, given the impact these barriers have on perception of care, efforts should be made to decrease perceived barriers to integrated behavioural health care among non-PCM team members.

Using Pill Identification Calls to Poison Centers as a Marker of Drug Abuse at Three Texas Military Bases.

OBJECTIVES: Opioid abuse is a growing problem in civilian communities, and it has developed in the military as well. Telephone calls to poison centers requesting pill identification (ID) is a marker of drug abuse. This study identifies the number of pill ID calls made to the poison centers from areas containing and surrounding three Texas military bases during an 8-year period. METHODS: We performed a retrospective observational study identifying calls to certified poison centers in Texas from 2002 to 2009 that identified hydrocodone tablets and other pain medications. We noted the calls made from ZIP codes containing and surrounding the three largest military bases in Texas. RESULTS: We reviewed 75,537 drug ID calls for any drug from the ZIP codes of interest. Total drug ID calls increased 105% and the number of calls for hydrocodone increased 463%. CONCLUSIONS: In our study most of the drug ID calls from military communities in Texas were for hydrocodone. The rate of calls for hydrocodone increased more than the rate of calls for other analgesics from 2002 to 2009. Using drug ID calls as a surrogate of drug abuse, our results suggest that hydrocodone abuse has increased within military communities and that poison center data can be a reliable surrogate for prescription drug abuse near military bases. Future studies are needed to further understand the extent of this problem in military and civilian communities. We can use this information to heighten awareness, influence prescription practices, establish practice guidelines, and develop educational programs to mitigate the increasing rate of prescription analgesic abuse in the United States.

Determination of airborne concentrations of dichlorvos over a range of temperatures when using commercially available pesticide strips in a simulated military guard post.

Dichlorvos is a chemical compound which has been used for decades as a pesticide. Potential inhalational exposure to dichlorvos vapor associated with using commercially-based, dichlorvos-impregnated resin strips in a simulated military guard post was evaluated. A varying number of these pesticide strips, ranging from the manufacturer's guidelines ((3)-16 g strips) up to a full package of strips ((12)-16 g strips), were placed in a small, enclosed space (2.31 m x 2.26 m x 2.44 m, 12.7 m3), which was similar in size to a typical military guard post. Static air sampling was then conducted to simulate personal air sampling, followed by analysis using OSHA Method 62 (GC-ECD). Air sampling was conducted over a range of discrete temperatures (26-38˚C) which approximated average ambient temperatures expected in a variety of deployed environments. Air sampling in this range was conducted to determine the airborne concentration generated at each temperature setting. Airborne concentrations were then compared to established short term military exposure guidelines (MEGs) and the 8-hr OSHA permissible exposure limit (PEL) for dichlorvos (both criteria limits are 0.99 mg/m3). Results from air sampling indicated that exceeding the manufacturer-recommended number of strips for the workspace volume and environmental conditions produced airborne dichlorvos concentrations above established occupational standards (1.77-3.70 mg/m3). Such exposures may potentially lead to adverse effects, such as loss of mental and visual acuity for guard post watch standers who employ more strips within a space than recommended per the manufacturer for the size of the space. However, concentrations of airborne dichlorvos generated when adhering to manufacturer's guidelines based on workspace volume resulted in levels of 0.16-0.39 mg/m3 for 1-hr and 8-hr timeframes, which were below the established occupational health limits. While dichlorvos-impregnated strips are not currently recommended for use in manned workspaces for periods > 4 hr, findings suggest that prolonged use (8 hr) of similar pesticide strips within manned spaces to repel and/or kill disease-carrying insects may be possible without experiencing adverse health effects.

Payment or Reimbursement for Certain Medical Expenses for Camp Lejeune Family Members. Final rule.

The Department of Veterans Affairs (VA) adopts as final an interim final rule addressing payment or reimbursement of certain medical expenses for family members of Camp Lejeune veterans. Under this rule, VA reimburses family members, or pays providers, for medical expenses incurred as a result of certain illnesses and conditions that may be associated with contaminants present in the base water supply at U.S. Marine Corps Base Camp Lejeune (Camp Lejeune), North Carolina, from August 1, 1953, to December 31, 1987. Payment or reimbursement is made within the limitations set forth in statute and Camp Lejeune family members receive hospital care and medical services that are consistent with the manner in which we provide hospital care and medical services to Camp Lejeune veterans. The statutory authority has since been amended to also include certain veterans' family members who resided at Camp Lejeune, North Carolina, for no less than 30 days (consecutive or nonconsecutive) between August 1, 1953, and December 31, 1987. This final rule will reflect that statutory change and will address public comments received in response to the interim final rule.

Diseases Associated With Exposure to Contaminants in the Water Supply at Camp Lejeune. Final rule.

The Department of Veterans Affairs (VA) amends its adjudication regulations regarding presumptive service connection, adding certain diseases associated with contaminants present in the base water supply at U.S. Marine Corps Base Camp Lejeune (Camp Lejeune), North Carolina, from August 1, 1953, to December 31, 1987. This final rule establishes that veterans, former reservists, and former National Guard members, who served at Camp Lejeune for no less than 30 days (consecutive or nonconsecutive) during this period, and who have been diagnosed with any of eight associated diseases, are presumed to have incurred or aggravated the disease in service for purposes of entitlement to VA benefits. In addition, this final rule establishes a presumption that these individuals were disabled during the relevant period of service for purposes of establishing active military service for benefits purposes. Under this presumption, affected former reservists and National Guard members have veteran status for purposes of entitlement to some VA benefits. This amendment implements a decision by the Secretary of Veterans Affairs that service connection on a presumptive basis is warranted for claimants who served at Camp Lejeune during the relevant period and for the requisite amount of time and later develop certain diseases.

General practitioners' approach to malingering in basic military training centres.

OBJECTIVES: Malingering can be defined as the abuse of the right to benefit from the health services. In this study, the frequency of the malingering cases in Basic Military Training Centres (BMTCs) and the behaviours and the attitudes of the military physicians towards the recruits who are suspected malingerers were described. METHOD: A total of 17 general practitioners in nine different BMTCs in different regions of Turkey constitute the universe of this descriptive study. In the questionnaire, there were a total of 30 questions about the descriptive characteristics of the participants and their attitudes and behaviours towards malingering. Informed consent form and a questionnaire were applied through the intranet via participants' emails. In the study, 15 physicians were reached with a response rate of 88.2%. RESULTS: All of the physicians suspected malingering in some of the soldiers who were examined. A total of 80% of the physicians (n=12) suspected malingering in at least 10% of the patients they examined. Only 13.3% of the physicians (n=2) had officially diagnosed a case of malingering in the last training period. All of the participants stated that they did not report the official decision for every soldier suspected of malingering. Instead of reporting official decision for malingering, the military physicians apply alternative procedures for suspected malingerers. CONCLUSIONS: In countries where the military service is compulsory, prevalence of malingering is estimated to be higher (approximately 5-25%). The problem of malingering is often underestimated due to the fact it is usually overlooked. Malingering remains a problem for the entire military healthcare system, due to the difficulties in exact diagnosis. Therefore, it can be useful to take some practical administrative measures for the soldiers who are prone to malingering, in order to discourage the behaviour.

Anatomic, Geographic, and Taxon-Specific Relative Risks of Carbapenem Resistance in the Health Care System of the U.S. Department of Defense.

Carbapenem-resistant Pseudomonas aeruginosa, Acinetobacter spp., and Enterobacteriaceae pose urgent public health threats. The differential burden, relative risks, associations with antimicrobial consumption, and temporal trends of those taxa in large, geographically diverse U.S. health systems remain under reported. Electronic records of all patients in a geographically dispersed 280-hospital managed-care system from 2005 to 2014 were reviewed. Carbapenem-resistant strains were identified based on Clinical and Laboratory Standards Institute guidelines and breakpoints. A total of 360,000 potentially carbapenem-resistant strains were identified from 14.7 million cultures (80% infecting and 20% surveillance). Isolation of bacteria overseas or isolation from the bloodstream was associated with a higher relative risks of carbapenem resistance (CR; P < 0.0001). Enterobacteriaceae were isolated 11 times more frequently than P. aeruginosa and Acinetobacter spp. However, compared to Enterobacteriaceae, the CR levels were 73-fold and 210-fold higher in P. aeruginosa and Acinetobacter spp., respectively. Significant differences in the relative risk of CR between taxa, anatomic, and geographic locations persisted after adjustment for other variables, the biggest differences occurring between taxa. Overall, CR rates increased for Enterobacteriaceae (P = 0.03) and decreased for Acinetobacter spp. and P. aeruginosa (P < 0.0001). These data provide a useful baseline for resistance trending and have implications for surveillance. Infections acquired overseas and bloodstream infections are particularly important areas for continued monitoring.
