Simultaneous norovirus outbreak in three Portuguese army bases in the Lisbon region, December 2017.

INTRODUCTION: Norovirus outbreaks frequently occur in communities and institutional settings acquiring a particular significance in armed forces where prompt reporting is critical. Here we describe the epidemiological, clinical and laboratorial investigation of a multicentre gastroenteritis outbreak that was detected simultaneously in three Portuguese army units with a common food supplier, Lisbon region, between 5 and 6 December 2017. METHODS: Questionnaires were distributed to all soldiers stationed in the three affected army units, and stool specimens were collected from soldiers with acute gastrointestinal illness. Stool specimens were tested for common enteropathogenic bacteria by standard methods and screened for a panel of enteric viruses using a multiplex real-time PCR assay. Food samples were also collected for microbiological analysis. Positive stool specimens for norovirus were further genotyped. RESULTS: The three simultaneous acute gastroenteritis outbreaks affected a 31 (3.5%) soldiers from a total of 874 stationed at the three units and lasted for 2 days. No secondary cases were reported. Stool specimens (N=11) were negative for all studied enteropathogenic agents but tested positive for norovirus. The recombinant norovirus GII.P16-GII.4 Sydney was identified in all positive samples with 100% identity. CONCLUSIONS: The results are suggestive of a common source of infection plausibly related to the food supplying chain. Although centralisation of food supplying in the army has economic advantages, it may contribute to the multifocal occurrence of outbreaks. A rapid intervention is key in the mitigation of outbreak consequences and in reducing secondary transmission.

Is it time to use nucleic acid amplification tests for identification of persons with sexually transmitted infections?: evidence from seroprevalence and behavioral epidemiology risk surveys in men with chlamydia and gonorrhea.

Chlamydia and gonorrhea are common sexually transmitted infections (STIs) that can cause multiple problems, and can be easily treated, but frequently present without symptoms. Because of this, commonly used syndromic diagnosis misses a majority of infected persons. Previously, diagnostic tests were expensive and invasive, but newer nucleic-acid amplification tests (NAATs) are available that use urine to non-invasively test for these infections. These analyses used data from seroprevalence studies conducted in five militaries. Data included self-reported current symptoms of STIs as well as chlamydia and gonorrhea NAAT results. A total of 4923 men were screened for chlamydia and gonorrhea from these 5 militaries during April 2016 to October 2017. The combined prevalence of chlamydia and gonorrhea in these five militaries ranged from 2.3% in Burundi to 11.9% in Belize. These infections were not successfully identified by symptomology; for example, only 2% of cases in Belize reported symptoms. In three of the five countries there was no statistical association between symptoms and positive NAAT results. The majority of individuals with these infections (81% to 98%) would be undiagnosed and untreated using only symptomology. Therefore, using symptoms alone to diagnose cases of chlamydia and gonorrhea is not an effective way to control these infections. We propose that automated, cartridge-based NAATs, be considered for routine use in diagnosing those at risk for STIs.

US military spouses' experiences transitioning abroad: A narrative analysis.

Moving to a new country and culture has emotional, social, financial, health, and cultural consequences. Military spouses face a wide range of stressors when relocating or sojourning, placing them at risk for a variety of health challenges. The aim of this study was to describe the transition experiences of military spouses who sojourn abroad as part of a service member's assignment. Using qualitative narrative inquiry, semi-structured interviews of 13 US military spouses living in Italy were conducted. Narrative thematic and structural analysis was used to analyze the data. Six themes represent the transition experience: adding stress to an already stressful situation, managing a new set of worries and fears surrounded by the unknown, reestablishing an everyday life from chaos, battling social, personal, and physical isolation, reinventing myself to move beyond simply functioning to control, and pondering about life, returning, and repatriation. Internationally, the nursing profession has a responsibility to understand the transition experience of military spouses to overseas assignments so appropriate strategies aimed at strengthening resiliency, building cultural flexibility, and maintaining health and well-being can be provided, while minimizing negative consequences. Additionally, nurses and health care providers can play a role by continually developing culturally congruent and sensitive practice.

Association of Suicide Risk With Transition to Civilian Life Among US Military Service Members.

Importance: Although interest is high in addressing suicide mortality after the transition from military to civilian life, little is known about the risk factors associated with this transition. To support the ongoing suicide surveillance work of the US Department of Veterans Affairs (VA) Office of Mental Health and Suicide Prevention, examining these factors is important for targeting suicide prevention efforts. Objective: To examine the prevalence, patterns, and associated characteristics of suicide mortality among US service members after separation from military active status. Design, Setting, and Participants: This retrospective population-based cohort study obtained demographic and military service data from the VA/Department of Defense Identity Repository. Individuals who served on active duty in the US Army, Navy, Air Force, Marine Corps, or Coast Guard after September 11, 2001, and who separated from active status between January 1, 2010, and December 31, 2017, were included in the cohort. Data analyses were conducted from September 9, 2019, to April 1, 2020. Main Outcomes and Measures: Suicide mortality within 6 years after separation from military service. Results: A total of 1 868 970 service members (1 572 523 men [84.1%]; mean [SD] age at separation, 30.9 [9.9] years) separated from the military during the study period. Through the end of the study period (December 31, 2017), 3030 suicides (2860 men and 170 women) were identified as having occurred within 6 years of separation from the military. Statistically significant differences in suicide risk were found by demographic and military service characteristics. Suicide rates after separation were time dependent, generally peaking 6 to 12 months after separation and declining only modestly over the study period. Male service members had a statistically significantly higher hazard of suicide than their female counterparts (hazard ratio [HR], 3.13; 95% CI, 2.68-3.69). Younger individuals (aged 17-19 years; HR, 4.46 [95% CI, 3.71-5.36]) had suicide hazard rates that were approximately 4.5 times higher than those who transitioned at an older age (≥40 years). Service branch remained a risk factor for suicide even 6 years after separation; those who separated from the Marine Corps (HR, 1.55; 95% CI, 1.36-1.78) and the Army (HR, 1.48; 95% CI, 1.31-1.67) had a higher hazard than those who transitioned from the Air Force. The hazard for those who separated from the active component was higher than for those who separated from the reserve component (HR, 1.29; 95% CI, 1.18-1.42). Service members with a shorter length of service had a higher hazard (HR, 1.26; 95% CI, 1.11-1.42) than those with a longer service history. Conclusions and Relevance: Results of this study show that not all service members who recently transitioned from military life had the same risk of suicide. The data suggest that awareness of military service and demographic characteristics can help identify those most at risk for suicide to target prevention efforts.

Sentinel Case of COVID-19 at Fort Stewart, GA in a National Guard Soldier Participating in Annual Training: A Case Report.

For healthcare providers, specifically military and federal public health personnel, prompt and accurate diagnosis and isolation of SARS-CoV-2 novel coronavirus patients provide a two-fold benefit: (1) directing appropriate treatment to the infected patient as early as possible in the progression of the disease to increase survival rates and minimize the devastating sequelae following recovery and remission of symptoms; (2) provide critical information requirements that enable commanders and public health officials to best synchronize policy, regulations, and troop movement restrictions while best allocating scarce resources in the delicate balance of risk mitigation versus mission readiness. Simple personal protective measures and robust testing and quarantine procedures, instituted and enforced aggressively by senior leaders, physicians, and healthcare professionals at all levels are an essential aspect of the battle against the COVID-19 pandemic that will determine the success or failure of the overall effort. As consideration, the authors respectfully submit this vignette of the first confirmed positive COVID-19 case presenting to the Emergency Department at Winn Army Community Hospital, Fort Stewart, Georgia.

Virus detections among patients with severe acute respiratory illness, Northern Vietnam.

Severe acute respiratory illness (SARI) is a major cause of death and morbidity in low- and middle-income countries, however, the etiologic agents are often undetermined due to the lack of molecular diagnostics in hospitals and clinics. To examine evidence for select viral infections among patients with SARI in northern Vietnam, we studied 348 nasopharyngeal samples from military and civilian patients admitted to 4 hospitals in the greater Hanoi area from 2017-2019. Initial screening for human respiratory viral pathogens was performed in Hanoi, Vietnam at the National Institute of Hygiene and Epidemiology (NIHE) or the Military Institute of Preventative Medicine (MIPM), and an aliquot was shipped to Duke-NUS Medical School in Singapore for validation. Patient demographics were recorded and used to epidemiologically describe the infections. Among military and civilian cases of SARI, 184 (52.9%) tested positive for one or more respiratory viruses. Influenza A virus was the most prevalent virus detected (64.7%), followed by influenza B virus (29.3%), enterovirus (3.8%), adenovirus (1.1%), and coronavirus (1.1%). Risk factor analyses demonstrated an increased risk of influenza A virus detection among military hospital patients (adjusted OR, 2.0; 95% CI, 1.2-3.2), and an increased risk of influenza B virus detection among patients enrolled in year 2017 (adjusted OR, 7.9; 95% CI, 2.7-22.9). As influenza A and B viruses were commonly associated with SARI and are treatable, SARI patients entering these hospitals would benefit if the hospitals were able to adapt onsite molecular diagnostics.

Perceptions of health and healthcare in ex-Army residents of Tameside: a pilot qualitative study.

BACKGROUND: Local authorities and other service providers need data on their local ex-military communities to be able to plan services. However, published research and data may not be applicable to the local population. Qualitative research offers a relatively low-cost way to get insights into the needs of local ex-military communities. METHODS: A pilot study using in-depth interviews with a small convenience sample of former ex-Army residents of Tameside. Framework analysis was used to identify and group themes arising from the data. This study was conducted using the Consolidated Criteria for Reporting Qualitative Research. RESULTS: While participants saw mental health as a particular challenge, they felt that it tends to get disproportionate attention relative to other needs. The study identified potential barriers to accessing health services that arise from an interaction between aspects of military and civilian healthcare culture and practices. Participants also said that military service could affect the health of both partners and children and that these effects might be more pronounced at key times, such as during adolescence. CONCLUSION: Participants' perceptions of the health of former members of the Armed forces reflect the published epidemiological literature. This suggests that qualitative data can be valid for understanding the health needs of local ex-military communities. Further research is needed to test the findings here with a broader group of ex-military personnel, to explore the barriers faced in accessing healthcare and to understand the health needs of the families of ex-service personnel.

Outbreak of cyclosporiasis in a U.S. Air Force training population, Joint Base San Antonio-Lackland, TX, 2018.

Diarrheal illnesses have an enormous impact on military operations in the deployed and training environments. While bacteria and viruses are the usual causes of gastrointestinal disease outbreaks, 2 Joint Base San Antonio-Lackland, TX, training populations experienced an outbreak of diarrheal illness caused by the parasite Cyclospora cayetanensis in June and July 2018. Cases were identified from outpatient medical records and responses to patient questionnaires. A confirmed case was defined by diarrhea and laboratory confirmation, and patients without a positive lab were classified as suspected cases. In cluster 1, 46 suspected and 7 confirmed cases occurred among technical training students who reported symptom onset from 12 June to 21 June. In cluster 2, 18 suspected and 14 confirmed cases in basic military training trainees reported symptom onset from 29 June to 8 July. Numerous lessons from cluster 1 were applied to cluster 2. Crucial lessons learned during this cyclosporiasis outbreak included the importance of maintaining clinical suspicion for cyclosporiasis in persistent gastrointestinal illness and obtaining confirmatory laboratory testing for expedited diagnosis and treatment.

Update: Lightning strike injuries, active component, U.S. Armed Forces, 2008-2017.

During 2008-2017, a total of 241 service members had incident lightning-related medical encounters with ICD-9 or ICD-10 codes that documented specific lightning-associated injuries or illnesses. The crude overall incidence rate of lightning strike injury during the surveillance period was 1.9 cases per 100,000 person-years. Compared to their respective counterparts, overall rates of lightning strike injury were higher among males, those aged 20-29 years, non-Hispanic whites, Army members, enlisted service members, those in combat-specific occupations, and those stationed in the Southern region of the U.S. During the surveillance period, there was a peak in incidence of lightning strike injury during 2015, as well as two smaller peaks in 2011 and 2013. "Disturbance of skin sensation," headache, limb pain, and burns were the four most frequent diagnoses during medical encounters for incident lightning strike injuries. The largest numbers of incident lightning strike injuries occurred in June, July, August, and September. Service members who routinely train and work outdoors should be vigilant about the dangers of lightning, especially in field settings during summer months.

Surveillance for norovirus and enteric bacterial pathogens as etiologies of acute gastroenteritis at U.S. military recruit training centers, 2011-2016.

An estimated 179 million cases of acute gastroenteritis (AGE) occur each year in the U.S. and AGE is commonly reported within both training and deployed U.S. military populations. Beginning in 2011, the Operational Infectious Diseases laboratory at Naval Health Research Center (NHRC) has undertaken routine surveillance of four U.S. military training facilities to systematically track the prevalence of AGE and to establish its etiologies among U.S. military recruits. Employing both molecular and standard microbiological techniques, NHRC routinely assays for pathogens of direct military relevance, including norovirus genogroups I and II, Salmonella, Shigella, and Campylobacter. During its initial surveillance efforts (2011-2016), NHRC identified norovirus as the primary etiology of both sporadic cases and outbreaks of AGE among trainees.

The Incidence of Intrauterine Device Provision in a Military Tertiary Care Facility From 2008-2014 Correlated to Contemporary Contraception Guidelines.

OBJECTIVE: To compare the incidence of intrauterine device (IUD) provision within the beneficiary population of a military tertiary care facility from 2008 to 2014 and in correlation with the publication of landmark contemporary guidelines for contraceptive use. METHODS: This was a retrospective observational study conducted in a military tertiary care facility using coding data to examine the trend in IUD provision correlated with published contraceptive practice guidelines from November 2008 to December 2014. The incidence of device provision was calculated per 1,000 female beneficiaries more than the age of 14 per month. The primary outcome was the mean monthly incidence of IUD in correlation with publication of the U.S. Medical Eligibility Criteria for Contraceptive Use (2010) and the Practice Guidelines from the American College of Obstetricians and Gynecologists (2011). For the subset of provisions that occurred by Family Medicine providers, the American Academy of Family Physicians (2012) was the second comparison clinical guideline. RESULTS: A total of 3,950 IUDs were placed during the study period. There was a statistically significant increase in the overall mean monthly incidence of IUD placement from 0.48 (SE 0.04) before guideline publication to 1.96 (SE 0.07) after the publications (analysis of variance, p < 0.01). Each publication was associated with a statistically significant sequential increase in the incidence of IUD provision. The incidence of provision remained elevated above baseline levels (range 0.93-3.03) for the 34 studied months after the 2011 American College of Obstetricians and Gynecologists Practice Guideline. CONCLUSION: The incidence of IUD provision significantly increased during the study period and in association with published guidelines guiding contraceptive management.

Use of complementary health approaches at military treatment facilities, active component, U.S. Armed Forces, 2010-2015.

Survey-based research has demonstrated the increasing use and acceptance of complementary and alternative medicine (CAM) in general and military populations. This report summarizes the use of three CAM procedures (chiropractic/osteopathic manipulation, acupuncture, and biofeedback) among active component service members from 2010 through 2015. Findings document a marked increase in the use of chiropractic/osteopathic manipulation and acupuncture procedures since 2010. The majority of the 240 military installations in this analysis provided chiropractic/osteopathic manipulation; more than three-quarters provided acupuncture; and approximately one-third provided biofeedback procedures. "Other and unspecified disorders of the back" was the most frequent condition for which chiropractic/osteopathic manipulation and acupuncture were used. "Non-allopathic lesions not elsewhere classified" was the second most frequent diagnosis during chiropractic/osteopathic manipulation-related visits. The second and third most frequent diagnoses during acupuncture-related visits were "acute and chronic pain" and "adjustment reaction," respectively. "Adjustment reaction" was the second most frequent diagnosis associated with biofeedback. Continued research is needed to gain a better understanding of why military personnel are using CAM and the role these procedures play in their health care.

Using Lean Six Sigma Methodology to Improve a Mass Immunizations Process at the United States Naval Academy.

Lean Six Sigma (LSS) is a process improvement methodology developed in the manufacturing industry to increase process efficiency while maintaining product quality. The efficacy of LSS application to the health care setting has not been adequately studied. This article presents a quality improvement project at the U.S. Naval Academy that uses LSS to improve the mass immunizations process for Midshipmen during in-processing. The process was standardized to give all vaccinations at one station instead of giving a different vaccination at each station. After project implementation, the average immunizations lead time decreased by 79% and staffing decreased by 10%. The process was shown to be in control with a capability index of 1.18 and performance index of 1.10, resulting in a defect rate of 0.04%. This project demonstrates that the LSS methodology can be applied successfully to the health care setting to make sustainable process improvements if used correctly and completely.

Initial deployment of the 14th Parachutist Forward Surgical Team at the beginning of the operation Sangaris in Central African Republic.

As part of the operation Sangaris begun in December 2013 in the Central African Republic, the 14th Parachutist Forward Surgical Team (FST) was deployed to support French troops. The FST (role 2 in the NATO classification) is a mobile surgical-medical treatment facility. The main goal of the FST is to assure the initial damage control surgery and resuscitation for combat casualties, allowing for the early evacuation to combat support hospitals (roles 3 or 4), where further treatments are completed. During the first trimester of the operation Sangaris, 42 patients were treated at FST, of whom 29 underwent surgery. Almost 50% of patients operated on were French servicemen. All admissions were emergency admissions. Orthopedic surgery represented two-thirds of surgical interventions executed as a result of the high proportion of limb injuries. Fifty percent of injuries were specifically linked to combat. Surgery in an FST is primarily dedicated to the treatment of combat casualties with hemorrhagic injuries, but additionally plays a part in supporting general medical care of French troops. Medical aid to the general civilian population is justifiable because of the presence of medical treatment facilities, even in the initial implementation of a military operation.

An outbreak of Campylobacter enteritis associated with a community water supply on a U.S. military installation.

An outbreak of acute gastroenteritis involving 249 persons, 32% of whom were hospitalized, occurred on a U.S. Army installation in 1990. Campylobacter jejuni was isolated from 81 of 163 (50%) persons cultured. Seventeen isolates of C. jejuni available for serotyping were Lior serotype 5. The outbreak remained restricted to one recruit barracks area and adjacent Junior Reserve Officer Training Corps cadet barracks. Infection of sequential cohorts of recruits over an interval of 3 weeks suggested a continuing or intermittent common source. Contaminated food was not implicated because affected persons ate at separate dining facilities and other facilities with the same food sources had no associated illnesses. There was a strong association between the amount of water consumed by recruits and risk of diarrhea (chi-square test for trend, p<0.001). Samples of drinking water collected in the affected area had no residual chlorine and when cultured yielded greater than 200 colonies of coliform bacteria per 100 mL of water sampled. Although Campylobacter was not isolated from water, living and dead birds were found in an elevated water storage tank providing drinking water to the affected area. This and other similar outbreaks indicate that contamination of water storage tanks can lead to large outbreaks of Campylobacter enteritis.

A longitudinal analysis of cigarette prices in military retail outlets.

OBJECTIVES: We conducted a longitudinal assessment of tobacco pricing in military retail outlets, including trends within each service branch. METHODS: We determined the price of a single pack of Marlboro Red cigarettes at military retail stores located in the continental United States, Alaska, and Hawaii and at their nearest Walmarts in spring 2011 and 2013 (n = 128 for pairs available at both assessments). RESULTS: The average difference between cigarettes sold in military retail outlets and Walmarts decreased from 24.5% in 2011 to 12.5% in 2013. The decrease was partially attributable to significant price decreases at Walmarts. The largest increases in cigarette prices occurred on naval installations. Potential savings at stores on several installations remained substantial in 2013; the largest approached $6 per pack. Stores on 17 military installations decreased cigarette prices during the study period. CONCLUSIONS: Tobacco can be purchased in military retail stores at substantial savings over civilian stores. If tobacco pricing is to cease to be an incentive for use among personnel, a revised military tobacco pricing policy is needed.
