Background: During the past two decades, there have been many changes in automotive and medical technologies, road infrastructure, trauma systems, and demographic changes which may have influenced injury outcomes. The aim of this study was to examine injury trends among traffic casualties, specifically private car occupants, hospitalized in Level I Trauma Centers (TC). Methods: A retrospective cohort study was performed based on data from the Israel National Trauma Registry. The data included occupants of private cars hospitalized in all six Level I TC due to a traffic collision related injury between January 1, 1998 and December 31, 2019. Demographic, injury and hospitalization characteristics and in-hospital mortality were analyzed. Chi-squared (X2) test, multivariable logistic regression models and Spearman's rank correlation were used to analyze injury data and trends. Results: During the study period, 21,173 private car occupants (14,078 drivers, 4,527 front passengers, and 2,568 rear passengers) were hospitalized due to a traffic crash. The percentage of females hospitalized due to a car crash increased from 37.7% in 1998 to 53.7% in 2019. Over a twofold increase in hospitalizations among older adult drivers (ages 65+) was observed, from 6.5% in 1998 to 15.7% in 2018 and 12.6% in 2019. While no increase was observed for severe traumatic brain injury, a statistically significant increase in severe abdominal and thoracic injuries was observed among the non-Jewish population along with a constant decrease in in-hospital mortality. Conclusions: This study provides interesting findings regarding injury and demographic trends among car occupants during the past two decades. Mortality among private car occupant casualties decreased during the study period, however an increase in serious abdominal and thoracic injuries was identified. The results should be used to design and implement policies and interventions for reducing injury and disability among car occupants. [ABSTRACT FROM AUTHOR]

Purpose: The objective of this study was to evaluate the relative contributions of different mechanisms of assault to injury and mortality in women in Israel. Methods: We identified females hospitalized between 2011 and 2020 following an assault, secondary to blunt, stabbing, or shooting mechanisms of injury, in the Israeli Program for Registration of Trauma Patients (National Trauma Registry). To avoid bias due to temporary hospitalizations for non-medical reasons, we included patients with injuries graded as Abbreviated Injury Scale ≥ 2. Results: Females accounted for 8.1% (926/11,486) of assault patients in the study population. Compared to males, females were older (40.7 vs. 31.0 years; p < 0.001), more commonly injured by the blunt trauma mechanism (72.1 vs. 48.6%; p < 0.001), and more commonly injured at a place of residence (50.9 vs. 8.2%; p < 0.001). There were no differences in the number of body areas injured, severe Injury Severity Score, and median hospitalization. Males were operated more commonly (44.6 vs. 40.0%; p = 0.008). Mortality in females and males was similar (2.8 vs. 2.3%; p = 0.43). Secondary analysis revealed that blunt injuries were responsible for 61.2% of the severe cases (ISS ≥ 16), 61.4% of the operations, 54.9% of the Intensive Care Unit (ICU) admissions, and 53.8% of the mortality observed in females. When compared to males injured by blunt trauma, females injured by this mechanism were older (43.0 ± 24.7 vs. 32.8 ± 16.1 years; p < 0.001) and had higher mortality (2.1 vs. 0.9%; p = 0.007). Conclusions: Assault by mechanisms other than stabbing and shooting should be recognized as a source of severe morbidity and mortality in females. [ABSTRACT FROM AUTHOR]

Electric bicycles and scooters have gained popularity among riders; studies assessing these device-related injuries have not specified ocular trauma. Our study examined the types and risk factors for ocular and periocular injuries associated with electric devices compared to motorcycle accidents. The study was conducted on the National Trauma Registry database from 20 trauma centers, including patients involved in accidents with electric bicycles, scooters, and motorcycles between 2014 to 2019. Injured riders were assigned into two groups: motorcycle group (M) and electric bicycle & scooter group (E). Data such as gender, age, protective gear use, ocular injury type, injury severity score (ISS), and ocular surgery were captured. Logistic regression models were conducted for injury types and the need for surgery. 8181 M-riders and 3817 E-riders were involved in an accident and hospitalized. E-riders suffered from ocular injury more than M-riders. Males were most vulnerable and the ages of 15–29. Orbital floor fracture was the most common injury, followed by ocular contusion, eyelid laceration, and other ocular wounds. Electric bicycle and scooter riders are more likely to suffer from ocular injury than motorcycle riders. Riders without helmets are at greater risk for injuries, specifically orbital floor fractures. ISS of 16 + was associated with injury demanding ocular surgery. [ABSTRACT FROM AUTHOR]

The infrastructure plays a twofold role in the course of the scientific and technological revolution. On the one hand, while the infrastructure itself does not create a material product, it does play the passive role of a system of "channels" and performs auxiliary, service functions. On the other hand, it directly influences the growth rates of the national economy, actively influences the organization and citing of production, stimulates (or inhibits) its development, and to a significant degree determines the population's way of life.

We derive an expression for the temporal fractional Talbot effect in delay lines with arbitrary orders of dispersion. We then demonstrate, experimentally and by numerical simulations, that a simple device consisting of a number of uniform fiber Bragg gratings or of waveguides can serve for such a tailored dispersive delay line for periodic optical pulses. The device produces temporally delayed and phase-shifted replicas of the original pulses, similarly to what happens in dispersive delay lines in the fractional Talbot effect. Such devices can be useful for compensation for the nonquadratic spectral phase of diode lasers, of dispersive elements in systems used for temporal imaging, real-time spectral analysis, and periodic pulse generation.
