ABSTRACT Introduction It has been shown that combat environment exposure, including burn pits that produce particulate matter 2.5 (PM2.5), is associated with lower respiratory tract disease in the military population with increased hypothetical risk of upper respiratory disease, but no study has been done that examines the effects of non-combat environmental exposures on the development of chronic rhinosinusitis (CRS) in the active duty population. The primary goal of this study is to evaluate how air pollution exposure correlates to the development of CRS in active duty service members in the United States. Methods The military electronic medical record was queried for active duty service members diagnosed with CRS by an otolaryngologist between January 2016 and January 2018, who have never deployed, stationed in the United States from 2015 to 2018 (n = 399). For each subject, the 1-year mean exposure of PM2.5, particulate matter 10 (PM10), nitrogen dioxide (NO2), and ozone was calculated. The control group was comprised of the same criteria except these patients were diagnosed with cerumen impaction and matched to the case group by age and gender (n = 399). Pollution exposure was calculated based on the Environmental Protection Agency’s data tables for each subject. Values were calculated using chi-square test for categorical variables and the Mann–Whitney U-test for continuous variables. Results Matched cases and controls (n = 399) with 33.1% male showed a statistically significant odds ratio (OR) of 5.99 (95% CI, 2.55-14.03) for exposure of every 5 µg/m3 of PM2.5 increase and the development of CRS when controlling for age, gender, and diagnosis year. When further adjusting for smoking status, the OR was still statistically significant at 3.15 (95% CI, 1.03-9.68). Particulate matter 10, ozone, and NO2 did not show any statistical significance. Odds ratios remained statistically significant when further adjusting for PM10 and ozone, but not NO2. Dose-dependent curves largely did not show a statistical significance; however, they did trend towards increased exposure of PM2.5 leading to an elevated OR. Conclusion This study showed that PM2.5 exposure is a major independent contributor to the development of CRS. Exposure to elevated levels produced statistically significant odds even among smokers and remained significant when controlling for other measured pollutants. There is still much to be understood about the genesis of CRS. From a pollution exposure perspective, a prospective cohort study would better elucidate the risk of the development of CRS among those exposed to other pollutants.

Abstract Background: Although representative data on caffeine intake in Americans are available these data do not include US service members (SMs). The few previous investigations in military personnel largely involve convenience samples. This cross-sectional study examined prevalence of caffeine use, daily consumption, and factors associated with use among United States active duty military service members (SMs). Methods: A stratified random sample of 200,000 SMs were asked to complete a questionnaire on their personal characteristics and consumption of caffeinated products. Eighteen percent (n=26,680) of successfully contacted SMs (n=146,365) completed the questionnaire. Results: Overall, 87% reported consuming caffeinated products ≥1 time/week. Mean ± standard error per-capita consumption (all participants) was 218±2 and 167±3 mg/day for men and women, respectively. Caffeine consumers ingested 243±2 mg/day (251±2 mg/day men, 195±3 mg/day women). On a body-weight basis, men and women consumed respectively similar caffeine amounts (2.93 vs 2.85 mg/day/kg; p=0.12). Among individual caffeinated products, coffee had the highest prevalence (68%), followed by sodas (42%), teas (29%), energy drinks (29%) and gums/candy/medications (4%). In multivariable logistic regression, characteristics independently associated with higher use prevalence (≥1 time/week) included female gender, older age, white race/ethnicity, higher body mass index, tobacco use or former use, greater alcohol intake, and higher enlisted or officer rank. Conclusion: Compared to National Health and Nutrition Survey Examination data, daily consumption (mg/day) by SMs was higher, perhaps reflecting higher mental and physical occupational demands on SMs.

Background: There is a high prevalence of combined shoulder instability in military patients. Short-term outcomes after 270° labral repair are promising; however, there is a paucity of longer term outcome data in this high-demand group of patients. Purpose: To report the midterm outcomes of active-duty military patients treated with 270° labral repair for combined shoulder instability. Study Design: Case series; Level of evidence, 4. Methods: All consecutive patients between January 2011 and January 2019 who underwent 270° labral repair by the senior surgeon with complete outcome scores were identified. All patients had experienced a shoulder dislocation after a traumatic event and had magnetic resonance imaging and intraoperative findings consistent with combined-type instability. A total of 52 patients met the inclusion criteria for the study, and all were active-duty servicemembers at the time of surgery. Results: The mean follow-up was 78.21 months (range, 24-117 months). There was a statistically significant increase in the mean American Shoulder and Elbow Surgeons score (from 44.92 to 89.31; P < .0001), Single Assessment Numeric Evaluation score (from 52.32 to 93.17; P < .0001), and Rowe instability score (from 46.63 to 91.35; P < .0001) from preoperatively to postoperatively. Mean pain decreased significantly as measured by the visual analog scale for pain (from 8.04 to 1.44; P < .0001). Range of motion in forward flexion (from 155.29° to 155.96°; P = .6793), external rotation (from 67.50° to 65.29°; P = .0623), and internal rotation (from T9.58 to T9.56; P = .9650) did not change significantly postoperatively. Outcomes did not differ significantly for patients who underwent surgery on their dominant shoulder versus those who underwent surgery on their nondominant shoulder, nor did outcomes vary with the type of anchor utilized (biocomposite vs all-suture). The overall rate of return to active duty was 92.31%. Conclusion: Midterm outcomes in this population of active-duty patients undergoing 270° labral repair for combined shoulder instability demonstrated a statistically and clinically significant improvement in patient-reported outcome scores, a significant decrease in pain, and an overall rate of return to active duty of 92.31%.

Objective This study aimed to assess trends and correlates of severe maternal morbidity at delivery among active duty women in the U.S. military, all of whom are guaranteed health care and full employment. Study Design Linked military personnel and medical encounter data from the Department of Defense Birth and Infant Health Research program were used to identify a cohort of delivery hospitalizations among active duty military women from January 2003 through August 2015. Cases of severe maternal morbidity were identified by applying 21- and 20-condition algorithms (with and without blood transfusion) developed by the Centers for Disease Control and Prevention. Rates (per 10,000 delivery hospitalizations) were reported overall and by specific condition. Multivariable Poisson regression models estimated associations with demographic, clinical, and military characteristics. Results Overall, 187,063 hospitalizations for live births were included for analyses. The overall 21- and 20-condition severe maternal morbidity rates were 111.7 (n = 2089) and 37.4 (n = 699) per 10,000 delivery hospitalizations, respectively. The 21-condition rate increased by 184% from 2003 to 2015; the 20-condition rate increased by 40%. Compared with non-Hispanic White women, the adjusted 21-condition rate of severe maternal morbidity was higher for Hispanic (adjusted rate ratio [aRR] = 1.28, 95% confidence interval [CI]: 1.13–1.46), non-Hispanic Black (aRR = 1.34, 95% CI: 1.21–1.49), Asian/Pacific Islander (aRR = 1.35, 95% CI: 1.13–1.61), and American Indian/Alaska Native (aRR = 1.39, 95% CI: 1.06–1.82) women. Rates also varied by age, clinical factors, and deployment history. Conclusion Active duty U.S. military women experienced an increase in severe maternal morbidity from 2003 to 2015 that followed national trends, despite protective factors such as stable employment and universal health care. Similar to other populations, military women of color were at higher risk for severe maternal morbidity relative to non-Hispanic White military women. Continued surveillance and further investigation into maternal health outcomes are critical for identifying areas of improvement in the Military Health System. Key Points

ABSTRACT Introduction Recent epidemiological evidence shows that shoulder and upper-arm complaints impose a substantial burden on the armed forces of the United States and create significant challenges for all components of the physical fitness domain of total force fitness. Clinicians, epidemiologists, and health-services researchers interested in shoulder and upper-arm injuries and their functional limitations rarely have objective, validated criteria for rigorously evaluating diagnostic practices, prescribed treatments, or the outcomes of alternative approaches. We sought to establish and quantify patient volume, types of care, and costs within the Military Health System (MHS) in assessing and managing active duty members with nonoperative shoulder and upper-arm dysfunction. Materials and Methods We performed a retrospective cohort study using data from the MHS Data Repository and MHS MART (M2) from fiscal year 2014 to identify active duty individuals with a diagnosis of shoulder and upper-arm injury or impairment defined by one of the International Classification of Disease Ninth Edition diagnosis codes that were selected to reflect nonoperative conditions such as fractures or infections. Statistical analyses include descriptive statistics on patient demographics and clinical visits, such as the range and frequency of diagnoses, number and types of appointments, and clinical procedure information following the diagnosis. We also examined treatment costs related to shoulder dysfunction and calculated the total cost to include medications, radiological, procedural, and laboratory test costs for all shoulder dysfunction visits in 2014 and the average cost for each visit. We further examined the category of each medication prescribed. Results A total of 55,643 individuals met study criteria and accrued 193,455 shoulder-dysfunction-related clinical visits in fiscal year 2014. This cohort represents approximately 4.8% of the 1,155,183 active duty service members assigned to the United States and its territories during FY 2014. Most patients were male (85.32%), younger (85.25% were under 40 years old), and Caucasian/White (71.12%). The most common diagnosis code was 719.41 (pain in joint, shoulder region; 42.48%). The majority of the patients 42,750 (76.8%) had four or fewer medical visits during the study period and 12,893 (23.2%) had more than four visits. A total of 4,733 patients (8.5%) underwent arthrocentesis aspiration or injection. The total cost for all visits was $65,066,767.89. The average and median cost for each visit were $336.34 (standard deviation was $1,493.87) and $163.11 (range was from 0 to $84,183.88), respectively. Three out of four patients (75.3%) underwent radiological examinations, and 74.2% of these individuals had more than one radiological examination. Medications were prescribed to 50,610 (91.0%) patients with the three most common being IBUPROFEN (12.21%), NAPROXEN (8.51%), and OXYCODONE-ACETAMINOPHEN (5.04%), respectively. Conclusions Nearly 1 in 20 active duty military service members presented for nonoperative care of shoulder and/or upper-arm dysfunction during FY2014. Further examinations of the etiology and potential impact of shoulder/upper-arm dysfunction on force readiness are clearly warranted, as are additional studies directed at identifying best practices for preventing injury-related dysfunction and determining best practices for the treatment of shoulder dysfunction to optimize service member fitness and force readiness.
