- Abstract：The accurate assessment and diagnosis of combat injuries are the basis for triage and treatment of combat casualties. A consensus on the assessment and diagnosis of combat injuries was made and discussed at the second annual meeting of the Professional Committee on Disaster Medicine of the Chinese People's Liberation Army (PLA). In this consensus agreement, the massive hemorrhage, airway, respiration, circulation and hypothermia (MARCH) algorithm, which is a simple triage and rapid treatment and field triage score, was recommended to assess combat casualties during the first-aid stage, whereas the abbreviated scoring method for combat casualty and the MARCH algorithm were recommended to assess combat casualties in level II facilities. In level III facilities, combined measures, including a history inquiry, thorough physical examination, laboratory examination, X-ray, and ultrasound examination, were recommended for the diagnosis of combat casualties. In addition, corresponding methods were recommended for the recognition of casualties needing massive transfusions, assessment of firearm wounds, evaluation of mangled extremities, and assessment of injury severity in this consensus.Keywords：Combat injuries;Assessment;diagnosis;Expert consensus0|0|0Updated：2026-03-12

Abstract：Background:Chronic exertional compartment syndrome (CECS) is a condition of pain induced by exercise, and it is characterized by muscle swelling and impaired muscle function in the lower leg. Given the diversity in the diagnosis and treatment of CECS, it is desirable to determine variables pertaining to prognosis and recovery. The purpose of this study is to identify prognostic factors for conservative treatment outcomes in servicemen with CECS who were treated at a Military Rehabilitation Center.Methods:Patients from all military services were referred from the special unit for lower leg pain at the Central Military Hospital, Utrecht, the Netherlands. Descriptive analysis was used to report the characteristics of the participants and their baseline measurements. Group differences were analyzed using a Student’s t-test or Mann-Whitney U test, according to the normality of the data distribution. Differences between the pre- and post-intervention outcomes were evaluated using the Wilcoxon signed rank test. To evaluate the magnitude of prognostic factors, a univariate logistic regression analysis was performed. The prognostic factors included age, body mass index, body fat percentage, self-efficacy beliefs, foot malalignment, intramuscular pressure, other comorbidities, protein and creatine use, smoking, alcohol use, complaint duration, physical demands, and duration of military service.Results:After the rehabilitation period, we observed 25 patients with a successful outcome, which was defined as a reduction in pain (≥2 points) during the capacity test measured using a verbal rating scale and 20 patients with an unsuccessful outcome. Factors demonstrating a limited increased odds ratio for an unsuccessful outcome included smoking, alcohol use, intramuscular pressure, a complaint duration of more than 6 months, and physical demands of service. However, these factors did not reach significance.Conclusion:This study did not identify any prognostic factors that predict the outcome of a rehabilitation program for CECS. A larger sample using an identical design might provide further evidence regarding prognostic factors, which would facilitate development of a model that predicts the outcomes of a rehabilitation program for CECS.Keywords：Lower leg pain;Observational study;Rehabilitation0|0|0Updated：2026-03-12 - Abstract：Background:Dietary supplement use (protein/amino acids, weight-loss supplements, performance enhancers) is common among U.S. military members. Reported dietary supplement use in deployed troops is limited and is of concern in settings where troops are exposed to high ambient temperatures, increased physical demands, and dehydration. Our objective was to describe dietary supplement use and adverse events (AEs) among deployed U.S. service members compared with their pre-deployment use.Methods:We conducted an institutional review board (IRB) approved, descriptive study in Afghanistan using a written questionnaire and collected demographic information, dietary supplement use before and during deployment, AEs associated with supplement use, and physical workout routines. Participants were U.S. military personnel of all branches of service deployed to Afghanistan. They were recruited in high-traffic areas in the combat theater. We analyzed the data with descriptive statistics. Paired t-test/Wilcoxon signed-rank test was conducted to examine the before/during deployment changes for continuous data, and McNemar’s chi-square test was conducted for categorical data. We constructed separate logistic regression models to determine the best predictors of increases or decreases in dietary supplement use, with demographic information, reasons for using supplements, and education requested/received as covariates in each model. All statistical tests were two-sided at a significance level of 5% (P<0.05).Results:Data were collected on 1685 participants. Ninety-seven of the participants were in the Army or Air Force. The participants were more likely to work out daily or more than once a day during deployment. Thirty-five percent of the participants reported no supplement use before or during deployment. The remaining 65% of participants reported increased use and increased frequency of use of supplements (e.g., daily) during deployment compared with pre-deployment. Additionally, more people followed label instructions strictly during deployment vs. predeployment. Overall, the frequency of self-reported AEs among supplement users remained consistent before and during deployment. The only significant difference noted was in problems falling or staying asleep, which increased during deployment. In the adjusted logistic regression models, the level of formal education, military branch, occupational specialty, education about dietary supplements, and certain reasons for using supplements (to boost energy, lose weight, gain muscle strength and mass, and as a meal replacement) were significant predictors of changes in supplement use.Conclusion:Deployed U.S. service members were more likely to use dietary supplements, use more than one supplement and use supplements more frequently during deployment than pre-deployment. No serious AEs were reported, but problems falling or staying asleep increased during deployment.Keywords：Military;Dietary supplement;Workout;Exercise;Adverse events0|0|0Updated：2026-03-12
- Abstract：Background:Repeat hospitalizations in veterans with inflammatory bowel disease (IBD) are under studied. The early readmission rate and potentially modifiable risk-factors for 90-day readmission in veterans with IBD were studied to avert avoidable readmissions.Methods:A retrospective cohort study was conducted using the data from veterans who were admitted to the Minneapolis VA Medical Center (MVMC) between January 1, 2007, and December 31, 2013, for an IBD-related problem. All-cause readmissions within 30 and 90 days were recorded to calculate early readmission rates. The multivariate logistic regression was used to identify the potential risk factors for 90-day readmission.Results:There were 130 unique patients (56.9% with Crohn’s disease and 43.1% with ulcerative colitis) with 202 IBD-related index admissions. The mean age at the time of index admission was 59.8±15.2 years. The median time to re-hospitalization was 26 days (IQR 10-49), with 30- and 90-day readmission rates of 17.3% (35/202) and 29.2% (59/202), respectively. Reasons for all-cause readmission were IBD-related (71.2%), scheduled surgery (3.4%) and non-gastrointestinal causes (25.4%). The following reasons were independently associated with 90-day readmission: Crohn’s disease (OR 3.90; 95% CI 1.82-8.90), use of antidepressants (OR 2.19; 95% CI 1.12-4.32), and lack of follow-up within 90 days with a primary care physician (PCP) (OR 2.63; 95% CI 1.32-5.26) or a gastroenterologist (GI) (OR 2.44; 95% CI 1.20-5.00). 51.0% and 49.0% of patients had documentation of a recommended outpatient follow-up with PCP and/or GI, respectively.Conclusion:Early readmission in IBD is common. Independent risk factors for 90-day readmission included Crohn’s disease, use of antidepressants and lack of follow-up visit with PCP or GI. Further research is required to determine if the appropriate timing of post-discharge follow-up can reduce IBD readmissions.Keywords：Inflammatory bowel disease;Readmission rates;Veterans affairs0|0|0Updated：2026-03-12

Abstract：Background:War-related traumas can lead to orthopedic and neurological disorders in victims. However, the scope of such disorders may expand months or even years after the trauma. Orthotic treatment as a rehabilitation process aims to enable people with disabilities to reach and maintain their optimal physical, sensory, intellectual, psychological, and social functional levels. This study aimed to investigate the rate of using orthoses among Iranian veterans with neuromuscular and skeletal disorders of the ankle and foot. Furthermore, the priorities of orthotic treatment in those veterans were explored.Methods:This qualitative study was a national health needs assessment conducted in 11 provinces of Iran during 2011–2016. A stakeholder research group was established to survey the veterans in respect to their demographic variables, activities of daily living, current health conditions, and rate of using orthoses.Results:Overall, 907 of the 1124 veteran participants completed the survey (response rate: 80.7%). Most of the veterans were men (97.7%), and their age and disability rate were 52.07±8.13 years and 31.92%±14.93%, respectively. Nearly 42% of the veterans had experience in using orthoses on a daily and weekly basis. As physical ambulation was the main problematic activity in veterans, most of them were using medical shoes and foot orthoses. Nearly 37% of veterans were in need of some type of lower limb orthoses on the contralateral side to compensate for their hip inequality. In sequential order, the most in need orthoses for veterans were foot orthoses (n=538), medical shoes (n=447), lower limb orthoses on the contralateral side (n=320), spinal orthoses (n=273), and upper limb orthoses (n=86).Conclusion:In spite of the high demands for orthoses among Iranian veterans with ankle and foot disorders, the use of orthoses is insufficient. Hence, there is a discrepancy between the current rate of orthoses use and its ideal situation, and more resources should be provided for service providers to be able to serve veterans. Moreover, veterans should be educated regarding orthoses, their use, and their impacts on the user’s health status. The findings of a needs assessment of orthoses can be used in strategic planning and decision making to improve health care services for Iranian veterans.Keywords：Needs assessment;Orthotic devices;Veterans;Ankle;Foot;War-related injuries0|0|0Updated：2026-03-12 -
Abstract：Background:Chronic diseases cause a tremendous burden to the military medical system. However, the prevalence rates of major chronic diseases among military officers remain unclear in China.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database for Chinese Technical Periodicals (VIP), PubMed and Web of Science were searched for studies (from 2000 to 2016) concerning 6 major chronic diseases: hypertension, hyperlipidemia, diabetes mellitus, heart diseases, cerebrovascular diseases, and chronic obstructive pulmonary diseases (COPD) in Chinese military officers following strict inclusion and exclusion criteria. Three researchers independently extracted data from the included studies, and a fourth researcher reviewed and solved every disagreement. Statistical analysis was performed with STATA 14.0 and R 3.3.2. Heterogeneity was evaluated by the I2 value. A random effect model was performed to combine the heterogeneous data. The Egger test was performed to test the publication bias.Results:A total of 90,758 military officers derived from 75 articles were pooled together. Publication bias was only observed in 37 studies reporting heart disease (PEgger test=0.01). The overall prevalence rates of hypertension, hyperlipidemia, diabetes mellitus, heart diseases, cerebrovascular diseases, and COPD were 46.6%(95% CI 41.8%–51.5%), 30.9%(26.4%–35.7%), 20.7%(16.5%–25.7%), 48.2%(41.7%–54.9%), 20.2%(14.8%–26.9%) and 16.6%(12.9%–21.0%), respectively. The prevalence rates of hypertension, diabetes, heart disease, cerebrovascular disease, and COPD, rather than hyperlipidemia, increased with age in Chinese military officers. Heart diseases (PQ-test<0.001) and hypertension (PQ-test<0.001) increased sharply in retired officers compared with officers in service. Cerebrovascular disease was more frequent in Northern Theater Command than in any other theater command (PQ-test<0.001).Conclusion:Major chronic diseases heavily affect Chinese military officers, especially retirees. Medical intervention should be enforced on the prevention of cerebrovascular diseases in those working in cold areas in the north, as well as hypertension and heart diseases in retirees.Keywords：Chronic diseases;Meta-analysis;hypertension;Hyperlipidemia;Diabetes;Cerebrovascular disease;chronic obstructive pulmonary disease0|0|0Updated：2026-03-12 - Abstract：Background:The diagnosis of bacterium-negative pulmonary tuberculosis (TB) and extra-pulmonary TB is challenging clinically. The detection of the anti-TB antibody has an important, auxiliary, clinical diagnostic value. Therefore, TB antibody detection kits should be screened and evaluated, and the reagents with the highest sensitivity and specificity should be chosen and used clinically.Methods:The diagnostic performance of 7 commercially available TB antibody detection kits (kits A, B, C, D, E, F and G) based on the gold immunoassay detection of immunoglobulin (Ig) G or IgM antibodies were simultaneously evaluated and compared in 62 TB cases and 56 non-TB cases in a laboratory. A retrospective analysis including 2549 cases was carried out to assess the clinical diagnosis values of bacteriological examinations and TB antibody tests (kits B and H used in the clinic).Results:The sensitivities of TB antibody kits A, B, C, D, E, F and G in the sera from 62 TB patients were 50.0%, 83.9%, 38.7%, 9.7%, 48.4%, 69.4% and 79.0%, respectively; the sensitivities in the sera from 24 smear-negative TB patients were 29.2%, 79.2%, 29.2%, 12.5%, 29.2%, 54.2% and 79.2%, respectively; the specificities in the sera from 56 non-TB patients were 73.2%, 25.0%, 85.7%, 96.4%, 78.6%, 78.6% and 50.0%, respectively. Of the 2549 clinically diagnosed cases, there were 1752 pulmonary TB cases, 505 extra-pulmonary TB cases, 87 old pulmonary TB cases and 205 non-TB cases. The positive results for smear, culture, TB antibody kit B and kit H in pulmonary TB cases were 39.8%(543/1365), 48.6%(372/765), 45.8%(802/1752) and 25.2%(442/1752), respectively; the results in extra-pulmonary TB cases were 3.4%(6/178), 5.8%(4/69), 35.4% (179/505), and 11.3%(57/505), respectively; the results in old pulmonary TB cases were 0%(0/64), 0%(0/30), 32.2%(28/87), and 9.2%(8/87), respectively; and the results in non-TB cases were 0%(0/121), 0%(0/56), 21.5%(44/205), and 2.4%(5/205), respectively. Of 624 smear-positive and/or culture-positive pulmonary TB cases, the sensitivities of antibody test kits B and H were 53.0% and 36.4%, respectively. Of 901 smear-negative and/or culture-negative pulmonary TB cases, the sensitivities of antibody test kits B and H were 42.5% and 19.0%, respectively. The positive rate of antibody detection in the bacterium-positive pulmonary TB cases was significantly higher than that in the bacterium-negative pulmonary TB cases (P<0.05).Conclusion:The colloidal gold-labeled TB antibody IgG detection assay is a simple, rapid and economical method that provides a better clinical auxiliary diagnosis value on TB, especially in smear-negative pulmonary TB and extrapulmonary TB. The production, quality control, screening and evaluation of antibody detection kits are very important for its clinical application.Keywords：Tuberculosis;Tuberculosis antibody test;Smear;culture0|0|0Updated：2026-03-12

Abstract：Sufficient sleep duration and good sleep quality are crucial to ensure normal physical and mental health, cognition and work performance for the common people, as well as astronauts. On-orbit sleep problem is very common among astronauts and has potential detrimental influences on the health of crewmembers and the safety of flight missions. Sleep in space is becoming a new medical research frontier. In this review we summarized on-orbit sleep problems of astronauts and six kinds of causes, and we presented the effects of lack of sleep on performance as well as mental and physical health, then we proposed seven kinds of countermeasures for sleep disturbance in spaceflight, including pharmacologic interventions, light treatment, crew selection and training, Traditional Chinese Medicine and so on. Furthermore, we discussed and oriented the prospect of researches on sleep in space.Keywords：Astronaut;On-orbit;Sleep;Countermeasure;Human spaceflight0|0|0Updated：2026-03-12 -
Abstract：Autoimmune disease management presents a significant challenge to medical science. Environmental factors potentially increase the risk of developing inflammatory and autoimmune diseases, such as multiple sclerosis, rheumatoid arthritis, and lupus. Among various environmental stresses, cigarette smoke and hypoxia have both been reported to lead to an enhanced risk of inflammatory and autoimmune diseases. In this review, we shed light on all reported mechanisms whereby cigarette smoke and a hypoxic environment can induce inflammatory and autoimmune diseases and discuss how hypoxic conditions influence the cigarette smoke-induced threat of inflammatory and autoimmune disease development. Cigarette smoke and hypoxia both lead to increased oxidative stress and production of reactive oxygen species and other free radicals, which have various effects including the generation of autoreactive pro-inflammatory T cells and autoantibodies, reductions in T regulatory (Treg) cell activity, and enhanced expression of pro-inflammatory mediators [e.g., interleukin-6 (IL-6), interleukin-4 (IL-4) and interleukin-8 (IL-8)]. Accordingly, smoking and hypoxic environments may synergistically act as potent environmental risk factors for inflammatory and autoimmune diseases. To our knowledge, no studies have reported the direct association of cigarette smoke and hypoxic environments with the risk of developing inflammatory and autoimmune diseases. Future studies exploring the risk of autoimmune disease development in smokers at high altitudes, particularly military personnel and mountaineers who are not acclimatized to high-altitude regions, are required to obtain a better understanding of disease risk as well as its management.Keywords：Inflammatory and autoimmune diseases;Cigarette smoke;Hypobaric hypoxia;Oxidative stress;Epigenetic modifications;Pro-inflammatory mediators;Autoantibody0|0|0Updated：2026-03-12
