ABSTRACT
BACKGROUND: Military and prehospital medical organizations invest significant resources to advance the treatment of trauma patients aiming to reduce preventable deaths. Focus is on hemorrhage control and volume resuscitation with blood products, with adoption of Remote Damage Control Resuscitation (RDCR) guidelines. The Israel Defense Forces Medical Corps (IDF-MC) has been using tranexamic acid and freeze-dried plasma (FDP) as part of its RDCR protocol for more than a decade. In recent years, low-titer group O whole blood (LTOWB) has been integrated, on IDF evacuation helicopters and expanded to mobile ambulances, complementing FDP use in treating trauma patients in state of profound shock. STUDY DESIGN AND METHODS: During the war that erupted in October 2023, the IDF-MC made a decision to bring LTOWB forward, and to equip every combat brigade level mobile intensive care units with LTOWB, onboard armored vehicles. The goal was to make whole blood available as close as possible to the point of injury and within minutes from time of injury. RESULTS AND DISCUSSION: We describe the IDF-MCs' efforts to bring LTOWB to the front lines and present four cases in which LTOWB was administered. All patients were young male, with significant blood loss following penetrating injuries. One patient died in the operating room, following hospital arrival and emergency thoracotomy. The others survived. Our initial experience with bringing LTOWB as close as possible to the point of injury during high intensity fighting is encouraging, showing patient benefit along with logistic feasibility. After action reports and data collection will continue.

PURPOSE: We evaluated hearing loss and general intelligence among persons with auricle anomalies and cleft lip and/or alveolus and/or cleft palate (CLAP). METHODS: A nationwide cross-sectional study of data recorded during 1966-2019, as mandatory pre-military recruitment of individuals. RESULTS: Of 3 182 892 adolescents, 548 were diagnosed with auricle anomalies and 2072 with CLAP. For the latter, the adjusted odds ratios for the low, low to medium and medium general intelligence categories compared to the highest category were 1.4 [95% CI 1.5-1.2], 1.2 [95% CI 1.4-1.1] and 1.1 [95% CI 1.2-0.9] respectively. The corresponding values for the auricle anomalies were not significant. CONCLUSIONS: General intelligence was impaired among individuals with CLAP, but no significant correlation was found among individuals suffering from auricle anomalies.
ABSTRACT
BACKGROUND: We assessed in a nationwide cohort the association between adolescent BMI and early-onset (< 40 years) type 2 diabetes among Israelis of Ethiopian origin. METHODS: Normoglycemic adolescents (range 16-20 years old), including 93,806 native Israelis (≥ 3rd generation in Israel) and 27,684 Israelis of Ethiopian origin, were medically assessed for military service between 1996 and 2011. Weight and height were measured. Data were linked to the Israeli National Diabetes Registry. Incident type 2 diabetes by December 31, 2016 was the outcome. Cox regression models stratified by sex and BMI categories were applied. RESULTS: 226 (0.29%) men and 79 (0.18%) women developed diabetes during 992,980 and 530,814 person-years follow-up, respectively, at a mean age of 30.4 and 27.4 years, respectively. Among native Israeli men with normal and high (overweight and obese) BMI, diabetes incidence was 9.5 and 62.0 (per 105 person-years), respectively. The respective incidences were 46.9 and 112.3 among men of Ethiopian origin. After adjustment for sociodemographic confounders, the hazard ratios for type 2 diabetes among Ethiopian men with normal and high BMI were 3.4 (2.3-5.1) and 15.8 (8.3-30.3) respectively, compared to third-generation Israelis with normal BMI. When this analysis was limited to Israeli-born Ethiopian men, the hazard ratios were 4.4 (1.7-11.4) and 29.1 (12.9-70.6), respectively. Results persisted when immigrants of other white Caucasian origin were the reference; and among women with normal, but not high, BMI. CONCLUSIONS: Ethiopian origin is a risk factor for early-onset type 2 diabetes among young men at any BMI, and may require selective interventions.

BACKGROUND: The association between hearing impairment and attention-deficit/hyperactivity disorder (ADHD) is unclear. Therefore, we aimed to assess this association in Israel's national sample of over 1.1 million adolescents. METHODS: We conducted a nationwide, population-based, cross-sectional study of all Israeli adolescents (n = 1,175,534, 58% males; mean age, 17 yrs) who were examined before mandatory military service during 2004 to 2020. Board-certified specialists confirmed diagnoses of hearing impairment and severe ADHD. MAIN OUTCOMES AND MEASURES: We compared the prevalence of severe ADHD in adolescents with and without hearing impairment. Associations were analyzed using logistic regression models and sensitivity analyses accounting for hearing impairment type (sensorineural vs. conductive) and severity. RESULTS: Of the 8,769 adolescents with hearing impairment, 57 were diagnosed with severe ADHD (prevalence = 0.65%). Of the 1,166,765 adolescents without hearing impairment, 3,936 were diagnosed with severe ADHD (prevalence = 0.29%). We found a significant association between hearing impairment and severe ADHD (odds ratio = 1.93 [95% confidence interval, 1.47-2.49]), which persisted in a multivariable model adjusted to age, sex, socioeconomic status, educational status, cognitive performance, and immigration status (odds ratio = 1.70 [95% confidence interval, 1.29-2.20]). The association also persisted when stratified by hearing impairment type (sensorineural vs. conductive) and severity. CONCLUSIONS: Adolescents with hearing impairment had 70% increased odds of severe ADHD. Study findings suggest that active screening of patients with hearing impairment for ADHD should be considered.

INTRODUCTION: Prehospital spinal immobilization using a cervical collar and a backboard has been standard practice for suspected spinal cord injuries (SCIs) since the 1960s. Multiple studies have shown that the disadvantages of the spinal backboard outweigh its advantages. This report aims to present a review of the current literature along with the revised IDF protocol regarding patients with suspected SCI. METHODS: In 2019, the IDF Medical Corps (IDFMC) convened a multidisciplinary expert committee to revise the IDFMC protocols regarding the use of spinal backboards. Prior to convening the committee, a review of the pertinent literature was done by conducting a thorough clinical evaluation in "PubMed" and "Google Scholar" databases to identify recent studies investigating traumatic SCI and the prehospital military use of spinal backboards. RESULTS: There were no documented studies that have managed to prove the efficacy of spinal backboards to prevent exacerbation of spinal injuries during mobilization. Despite being a good tool for extraction from vehicles and combat arenas, more than 11 studies have shown that backboards may even result in adverse outcomes such as pain due to the contact between board and skin, the formation of decubitus ulcers, hypothermia, and inadequate ventilation. CONCLUSION: In light of the evidence showing the potential harmful effects of the routine use of spinal backboards, the IDF guidelines have been revised and now recommends avoiding the routine use of spinal backboards and using a standard stretcher for transporting potential SCI patients. Current IDF guidelines recommend using a backboard for the extraction of an entrapped patient and for obtunded or unconscious patients with obvious deformity or mechanism for spinal trauma.
ABSTRACT
BACKGROUND: The prevalence of both asthma and early-onset diabetes is on the rise; however, the association between them remains unclear. We examined a possible association of asthma at adolescence with type 2 diabetes in young adulthood. METHODS: This is a nationwide, population-based study of 1 718 541 Israeli adolescents (57% males; mean age 17.3 years; range 16-19 years), examined before compulsory military service between 1992 and 2016, with data linked to the Israeli National Diabetes Registry. Asthma diagnosis and severity were determined by a board-certified pulmonologist and based on spirometry tests. RESULTS: Type 2 diabetes developed in 58/9090 (0.64%), 507/97 059 (0.52%), 114/23 332 (0.49%), and 7095/1 589 060 (0.44%) persons with moderate-to-severe, mild, inactive, and no history of asthma, respectively, during a mean follow-up >13 years. The respective odds ratios (ORs) were 1.33 (95% CI, 1.02-1.74), 1.17 (1.06-1.28), and 1.09 (0.9-1.31), considering those without asthma history as the reference, in a model adjusted for birth year, sex, body mass index, and other sociodemographic variables. The association persisted when the analysis accounted for coexisting morbidities, and when persons without asthma, individually matched by age, sex, birth year, and body mass index were the reference. Both mild and moderate-to-severe asthma were associated with type 2 diabetes before age 35 years: ORs 1.18 (1.05-1.34) and 1.44 (1.05-2.00), respectively. The strength of the association was accentuated over time. The effect was unchanged when adjusted for oral and inhaled glucocorticoid use. CONCLUSION: Adolescents with active asthma have higher risk to develop type 2 diabetes. This seems related to disease severity, independent of adolescent obesity status, apparent before age 35 years, and more pronounced in recent years.

CONTEXT: The long-term risk of type 2 diabetes in adolescents with nonalcoholic fatty liver disease (NAFLD) is unclear. OBJECTIVE: To assess type 2 diabetes risk among adolescents with NAFLD. DESIGN AND SETTING: A nationwide, population-based study of Israeli adolescents who were examined before military service during 1997-2011 and were followed until December 31, 2016. PARTICIPANTS: A total of 1 025 796 normoglycemic adolescents were included. INTERVENTIONS: Biopsy or radiographic tests were prerequisite for NAFLD diagnosis. Data were linked to the Israeli National Diabetes Registry. MAIN OUTCOME MEASURES: Type 2 diabetes incidence. RESULTS: During a mean follow-up of 13.3 years, 12 of 633 adolescents with NAFLD (1.9%; all with high body mass index [BMI] at baseline) were diagnosed with type 2 diabetes compared with 2917 (0.3%) adolescents without NAFLD. The hazard ratio (HR) for type 2 diabetes was 2.59 (95% confidence interval [CI], 1.47-4.58) for the NAFLD vs. the non-NAFLD group after adjustment for BMI and sociodemographic confounders. The elevated risk persisted in several sensitivity analyses. These included an analysis of persons without other metabolic comorbidities (adjusted HR, 2.75 [95% CI, 1.48-5.14]) and of persons with high BMI; and an analysis whose outcome was type 2 diabetes by age 30 years (adjusted HR, 2.14 [95% CI, 1.02-4.52]). The results remained significant when a sex-, birth year-, and BMI-matched control group was the reference (adjusted HR, 2.98 [95% CI, 1.54-5.74]). CONCLUSIONS: Among normoglycemic adolescents, NAFLD was associated with an increased adjusted risk for type 2 diabetes, which may be apparent before age 30 years.

Immigration from one cultural milieu to another has been associated with a greater risk for incident cardio-metabolic morbidity among adults. In this nationwide, population-based, cross-sectional study of data recorded from 1992 to 2016, we assessed the association between body mass index and blood pressure levels among adolescent immigrants, aged 16 to 19 years, of Ethiopian origin, and their secular trend of overweight and obesity. Adolescents of Ethiopian origin were classified as Israeli-born (n=16 153) or immigrants (N=23 487), with stratification by age at immigration. Adolescents whose fathers were at least 3 generations in Israel (n=277 789) served as a comparative group. Hypertensive-range blood pressure values adjusted for age, sex, and height served as outcome. Among adolescents of Ethiopian origin, overweight and obesity (body mass index ≥85th percentile), increased by 2.5 and 4-fold in males and females, respectively, during the study period, compared with a 1.5-fold increase among native Israeli-born males and females. The odds for hypertensive-range measurements increased with the length of residence in Israel: 7.3%, 10.6%, and 14.4% among males who immigrated at ages 12 to 19, 6 to 11.9, and 0 to 5.9 years, respectively; and 11.5%, 16.7%, and 19.3%, respectively, among females. Israeli-born Ethiopians had a significantly higher risk for hypertensive-range measurements at any body mass index level compared with native Israeli-born examinees, after adjusting for sociodemographic factors and health status. In conclusion, among Ethiopian Israeli adolescents, abnormal blood pressure correlates directly with the time-lapse since immigration. Immigrant populations require targeted surveillance and appropriate intervention.

BACKGROUND: Short stature was suggested as a risk factor for diabetes onset among middle age individuals, but whether this is the case among young adults is unclear. Our goal was to assess the association between height and incident diabetes among young men. METHODS AND FINDINGS: Incident diabetes was assessed among 32,055 men with no history of diabetes, from the prospectively followed young adults of the MELANY cohort. Height was measured at two time points; at adolescence (mean age 17.4±0.3 years) and grouped according to the US-CDC percentiles and at young adulthood (mean age 31.0±5.6 years). Cox proportional hazards models were applied. There were 702 new cases of diabetes during a mean follow-up of 6.3±4.3 years. There was a significant increase in the crude diabetes incidence rate with decreasing adolescent height percentile, from 4.23 cases/104 person-years in the <10th percentile group to 2.44 cases/104 person-years in the 75th≤ percentile group. These results persisted when clinical and biochemical diabetes risk factors were included in multivariable models. Compared to the 75th≤ percentile group, height below the 10th percentile was associated with a hazard ratio (HR) of 1.64 (95%CI 1.09-2.46, p = 0.017) for incident diabetes after adjustment for age, body mass index (BMI), fasting plasma glucose, HDL-cholesterol and triglyceride levels, white blood cells count, socioeconomic status, country of origin, family history of diabetes, sleep quality and physical activity. At age 30 years, each 1-cm decrement in adult height was associated with a 2.5% increase in diabetes adjusted risk (HR 1.025, 95%CI 1.01-1.04, p = 0.001). CONCLUSIONS: Shorter height at late adolescence or young adulthood was associated with an increased risk of incident diabetes among young men, independent of BMI and other diabetes risk factors.
