Abstract
Previous rural vascular trauma research has focused on case series dating back two decades. The current research aims to measure clinical decline in comparison to time to care in rural vascular trauma. This single-center retrospective cohort study included adult trauma patients with vascular injury who were admitted to a level II trauma center. Multivariable logistic regression assessed the effect of clinical decline based on arrival within the golden hour. 149 patients were included. For every 1 unit increase in the shock index ratio, there was 99.9% reduction in odds that the patient would arrive to the trauma center within the golden hour. This study is the first of its kind within the last two decades to comprehensively review rural vascular trauma. Our research showed clinical decline in SIR associated with prolonged time to care and will allow us to optimize pre-hospital care and transport in regions with prolonged arrival times.

Abstract
Kinetic models of solvent transport behaviors are widely used in rubber-solvent systems, and some key points are still worthy of attention. In this work, the Korsmeyer-Peppas and Peppas-Sahlin models were chosen to fit the transport behaviors of three aromatic solvents, benzene, toluene and p-xylene, in the hydrogenated nitrile rubber (HNBR)/ethylene propylene diene monomer (EPDM)-based vulcanizates. The different effects of the various selected transport times (ti) used for fitting on the results of the mathematical models were compared. Moreover, a method to obtain the n parameter for the Korsmeyer-Peppas model and the m parameter for the Peppas-Sahlin model at ti = 0 was discussed. It was found that the differences in values of ti greatly influenced the impact on the fitting results of all the parameters for the two models. In addition, the n parameter for the Korsmeyer-Peppas model along with the m parameter for the Peppas-Sahlin model, which can characterize the transport mechanism, showed differing applicability. But the n and m parameters at ti = 0 obtained by linear fitting showed similar rules with some differences in values. These discussions give important guidance for the application of kinetic transport models in rubber-solvent systems.

Abstract
Introduction Potential nutrient losses and mycotoxin accumulation caused by abnormal fermentation during transportation from cropland to dairy farms leads to the diseases incidence and threatens the health of dairy cows, then further causes financial losses. The aim of this study was to investigate the effects of different transportation times on the nutritional composition, mycotoxins, and microbial communities in whole-plant corn silage (WPCS). Methods Three groups were subjected to different transport times: DY, short (<200 min); ZY, medium time (300-500 min); and CY, long transport time (>600 min). WPCS were collected from the same field, and nutrient composition and microbial composition before and after transportation were analyzed. Results and discussion Our results showed that the temperature of WPCS was higher in the ZY and CY groups than in the DY group (P < 0.01). There were no significant differences in dry matter (DM), crude protein (CP), neutral detergent fiber (NDF), acid detergent fiber (ADF), ether extract (EE) and starch contents after different transportation times (P > 0.05), whereas the starch and water-soluble carbohydrates (WSC) contents in the CY group was significantly decreased after transport (P < 0.05). Similarly, the concentration of vomitoxin in the DY and CY groups declined markedly (P < 0.05) and the zearalenone content in the DY group also significantly decreased after transportation (P < 0.05). Regarding the analysis of microorganisms in WPCS, UniFrac-distance matrices and Shannon indices showed differences in the ZY group (P < 0.05), but fungal diversities were not influenced by the transport time (P > 0.05). In the ZY group, the relative abundance of Lactiplantibacillus decreased significantly after transportation (P > 0.05), but the relative abundances of unidentified_Chloroplast, Pantoea, Gluconobacter, unidentified Acetobacter and Acinetobacter increased markedly (P < 0.05). In addition, the relative abundances of Acetobacter and Gluconobacter in the CY group increased after transport (P < 0.05). Among fungal communities, a total of three, nine, and ten different fungal flora were observed in the DY, ZY, and CY groups, respectively, although no difference was found in fungal diversity. In conclusion, increased temperature, loss of starch, and mycotoxin variation were found with increased transport time. This might be the result of competition between bacteria and fungi, and novel technologies will need to be utilized for further exploration of the mechanism.

Abstract
The aim of this study was to discuss the differences in pre-hospital time intervals between rural and urban communities regarding emergency medical services (EMS). A systematic search was conducted through various relevant databases, together with a manual search to find relevant articles that compared rural and urban communities in terms of response time, on-scene time, and transport time. A total of 37 articles were ultimately included in this review. The sample sizes of the included studies was also remarkably variable, ranging between 137 and 239,464,121. Twenty-nine (78.4%) reported a difference in response time between rural and urban areas. Among these studies, the reported response times for patients were remarkably variable. However, most of them (number (n) = 27, 93.1%) indicate that response times are significantly longer in rural areas than in urban areas. Regarding transport time, 14 studies (37.8%) compared this outcome between rural and urban populations. All of these studies indicate the superiority of EMS in urban over rural communities. In another context, 10 studies (27%) reported on-scene time. Most of these studies (n = 8, 80%) reported that the mean on-scene time for their populations is significantly longer in rural areas than in urban areas. On the other hand, two studies (5.4%) reported that on-scene time is similar in urban and rural communities. Finally, only eight studies (21.6%) reported pre-hospital times for rural and urban populations. All studies reported a significantly shorter pre-hospital time in urban communities compared to rural communities. Conclusions: Even with the recently added data, short pre-hospital time intervals are still superior in urban over rural communities.

Abstract
Quantitative assessments of long-term, national-scale responses of groundwater quality to pesticide applications are essential to evaluate the effectiveness of pesticide regulations. Retardation time in the unsaturated zone (Ru) was estimated for selected herbicides (atrazine, simazine, and bentazon) and degradation products (desethylatrazine (DEA), desisopropylatrazine (DIA), desethyldesisopropylatrazine (DEIA), and BAM) using a multidecadal time series of groundwater solute chemistry (∼30 years) and herbicide sales (∼60 years). The sampling year was converted to recharge year using groundwater age. Then, Ru was estimated using a cross-correlation analysis of the sales and the frequencies of detection and exceedance of the drinking water standard (0.1 μg/L) of each selected compound. The results showed no retardation of the highly polar, thus mobile, parent compounds (i.e., bentazon), while Ru of the moderately polar compounds (i.e., simazine) was about a decade, and their degradation products showed even longer Ru. The temporal trends of the degradation products did not mirror those of the sale data, which were attributed to the various sale periods of the parent compounds, sorption of the parent compounds, and complex degradation pathways. The longer Ru in clayey/organic sediments than in sandy sediments further confirmed the role of soil-specific retardation as an important factor to consider in groundwater protection.

Abstract
Background: Patients presenting with a diagnosis of ruptured abdominal aortic aneurysm (RAAA) to community hospitals must be transported to tertiary care centers, where necessary resources are available. Unfortunately, guidelines for treatment of RAAA lack high-level evidence on the optimal resuscitation of RAAA patients during transport. We hypothesized that transfusion of packed red blood cells (PRBCs) during transport would not delay transport times in patients with RAAA. Methods: We performed a retrospective analysis of a prospective registry including prehospital data of patients with RAAA presenting to a single academic hospital in Western Pennsylvania between 2001 and 2019. Our primary outcomes were prehospital transport times: "transport interval" and "total interval." "Transport interval" is the duration from patient pickup at the outside hospital (OSH) to arrival at the receiving facility. "Total interval" is the duration from dispatch of the air medical transport to arrival of the patient to the receiving facility. We then compared two groups of patients, stratified by the receipt of PRBCs in transit, by reporting mean difference (95% confidence interval: CI) for continuous variables and percent difference (95% CI) for categorical variables. We performed two multivariate linear regression models to test if there was any effect of the receipt of PRBCs in transit on transport times. Results: We included 271 patients with RAAA transported by our air ambulance system who underwent an operation at the receiving facility, 99 (37%) of whom received PRBCs in transit. Mean ± standard deviation (SD) of the total intervals were 67 ± 28 and 71 ± 42 minutes, among patients who received or did not receive PRBCs in transit respectively, with no significant difference (p = 0.437). Following adjusted analysis, the receipt of PRBCs during transport was not associated with increased transport times, after accounting for age, hypotension, endovascular aneurysm repair (EVAR), and PRBC transfusion at the OSH. Conclusion: PRBC transfusion during air medical transport in patients with RAAA did not delay transport times.

Abstract
The first confirmed community transmission of coronavirus disease 2019 in Daegu Metropolitan City, South Korea, occurred on February 18, 2020. In the following 70-day period, approximately 6000 new cases occurred, severely impacting the medical service system. This study investigated the crisis-impact on the local emergency transport system.Emergency medical service activity reports were retrospectively reviewed to determine patient demographics and initial vital signs. Delay in reaching the patient, transporting the patient to the hospital, and returning to the fire station were assessed and categorized based on patients' initial vital signs. The study period was divided into 4 groups (1/1-2/18, 2/19-3/3, 3/4-3/31, and 4/1-04/30) and intergroup differences were analyzed.When compared to Period 1, the time-difference between the request to attend a scene and arrival at the scene was delayed in Periods 2, 3, and 4 by 4 minute 58 s, 3 minute 24 seconds, and 2 minute 20 seconds, respectively; that between arriving at the scene and at the hospital was delayed by 7 minute 43 seconds, 6 minutes 59 seconds, and 4 minutes 30 seconds, respectively; and that between arriving at the hospital and returning to the fire station was delayed by 29 minute 3 second, 25 minute 55 second, and 18 minute 44 second, respectively. In Period 2, for patients with symptoms of severe illness when compared to patients lacking such symptoms, the time-difference between the request to attend the scene and arrival at a hospital and between arrival at the hospital and returning to the fire station were 6 to 23 minute and 12 to 48 minute longer, respectively. Most of the delays impacted patients with a fever. In terms of condition, the statistical effect size for delay in transport time was from large to small: fever, hypoxia, abnormal respiratory rate, respiratory symptom, and hypotension.Outbreaks of infectious disease cause a paradoxical state in emergency medical transport systems, inducing delays in the transport of severely ill patients. Therefore, maintenance and improvement of the medical service system for both patients with infectious disease and those with other severe illnesses is required.

Abstract
BACKGROUND In the prehospital setting, the use of ambulance lights and sirens (L&S) has been found to result in minor decreases in transport times, but has not been studied in interfacility transportation. OBJECTIVE The objective of this study was to evaluate the indications for L&S and the impact of L&S on transport times in interfacility critical care transport. METHODS We performed a retrospective analysis using administrative data from a large, urban critical care transportation organization. The indications for L&S were assessed and the transport times with and without L&S were compared using distance matching for common transport routes. Median times were compared for temporal subgroups. RESULTS L&S were used in 7.3% of transports and were most strongly associated with transport directly to the operating room (odds ratio 15.8; 95% confidence interval 6.32-39.50; p < 0.001). The timing of the transport was not associated with L&S use. For all transports, there was a significant decrease in the transport time using L&S, with a median of 8 min saved, corresponding to 19.5% of the overall transportation time without L&S (33 vs. 41 min; p < 0.001). The reduction in transport times was consistent across all temporal subgroups, with a greater time reduction during rush hour transports. CONCLUSIONS The use of L&S during interfacility critical care transport was associated with a statistically significant time reduction in this urban, single-system retrospective analysis. Although the use of L&S was not associated with rush-hour transports, the greatest time reduction was associated with L&S transport during these hours.

Abstract
Background Should all out‐of‐hospital cardiac arrest (OHCA) patients be directly transported to cardiac arrest centers (CACs) remains under debate. Our study evaluated the impacts of different transport time and destination hospital on the outcomes of OHCA patients. Methods and Results Data were collected from 6655 OHCA patients recorded in the regional prospective OHCA registry database of Taoyuan City, Taiwan, between January 2012 and December 2016. Patients were matched on propensity score, which left 5156 patients, 2578 each in the CAC and non‐CAC groups. Transport time was dichotomized into <8 and ≥8 minutes. The relations between the transport time to CACs and good neurological outcome at discharge and survival to discharge were investigated. Of the 5156 patients, 4215 (81.7%) presented with nonshockable rhythms and 941 (18.3%) presented with shockable rhythms. Regardless of transport time, transportation to a CAC increased the likelihoods of survival to discharge (<8 minutes: adjusted odds ratio [aOR], 1.95; 95% CI, 1.11–3.41; ≥8 minutes: aOR, 1.92; 95% CI, 1.25–2.94) and good neurological outcome at discharge (<8 minutes: aOR, 2.70; 95% CI, 1.40–5.22; ≥8 minutes: aOR, 2.20; 95% CI, 1.29–3.75) in OHCA patients with shockable rhythms but not in patients with nonshockable rhythms. Conclusions OHCA patients with shockable rhythms transported to CACs demonstrated higher probabilities of survival to discharge and a good neurological outcome at discharge. Direct ambulance delivery to CACs should thus be considered, particularly when OHCA patients present with shockable rhythms.

Abstract
Simple Summary Factors, such as ambient conditions, travel duration and vehicle design/compartment location have an impact on the welfare of pigs during transport, carcass bruises and meat quality. Based on this, we aimed to assess the effects of these factors on blood creatine kinase, lactate and cortisol concentrations in 384 pigs and assess their relationships with trailer temperature, and pigs’ heart rate and gastrointestinal tract temperature, behavior, carcass damage scores and meat quality. Although increased blood cortisol and creatine-kinase levels appear to indicate a physical stress condition in transported pigs, the weak to moderate correlations with environmental and other animal welfare indicators suggest that blood stress parameters can only be used as a complementary measurement in the assessment of the pigs’ response to transport stress. Abstract The objective of this study was to assess the effects of the season, travel duration and trailer compartment location on blood creatine-kinase (CK), lactate and cortisol concentrations in 384 pigs and assess their relationships with trailer temperature, heart rate and gastrointestinal tract temperature (GTT), behavior, carcass damage scores and meat quality. Blood CK was greater in pigs transported in summer (p = 0.02), after 18 h transportation (p < 0.001) and in pigs located in C4, C5 and C10 (p = 0.002). In winter, the concentration of blood lactate was higher (p = 0.04) in pigs transported for 6 h in C5. Pigs located in C10 showed higher (p = 0.01) concentration of cortisol than those transported for 18h in C4 in summer. The highest correlations were between blood cortisol and GTT (r = 0.53; p < 0.001), and between blood CK and GTT (r = 0.41; p < 0.001), truck temperature (r = 0.42; p < 0.001), and pHu in the longissimus muscle (r = 0.41; p < 0.001). In conclusion, although increased blood cortisol and CK levels appear to indicate a physical stress condition in transported pigs, the weak to moderate correlations with environmental and other animal welfare indicators suggest that blood stress parameters can only be used as a complementary measurement in the assessment of the pigs’ response to transport stress.

Abstract
UNLABELLED Introduction Inter-facility transport of critically ill patients is associated with a high risk of adverse events, and critical care transport (CCT) teams may spend considerable time at sending institutions preparing patients for transport. The effect of mode of transport and distance to be traveled on on-scene times (OSTs) has not been well-described. Problem Quantification of the time required to package patients and complete CCTs based on mode of transport and distance between facilities is important for hospitals and CCT teams to allocate resources effectively. METHODS This is a retrospective review of OSTs and transport times for patients with hypoxemic respiratory failure transported from October 2009 through December 2012 from sending hospitals to three tertiary care hospitals. Differences among the OSTs and transport times based on the mode of transport (ground, rotor wing, or fixed wing), distance traveled, and intra-hospital pick-up location (emergency department [ED] vs intensive care unit [ICU]) were assessed. Correlations between OSTs and transport times were performed based on mode of transport and distance traveled. RESULTS Two hundred thirty-nine charts were identified for review. Mean OST was 42.2 (SD=18.8) minutes, and mean transport time was 35.7 (SD=19.5) minutes. On-scene time was greater than en route time for 147 patients and greater than total trip time for 91. Mean transport distance was 42.2 (SD=35.1) miles. There were no differences in the OST based on mode of transport; however, total transport time was significantly shorter for rotor versus ground, (39.9 [SD=19.9] minutes vs 54.2 [SD=24.7] minutes; P <.001) and for rotor versus fixed wing (84.3 [SD=34.2] minutes; P=0.02). On-scene time in the ED was significantly shorter than the ICU (33.5 [SD=15.7] minutes vs 45.2 [SD=18.8] minutes; P <.001). For all patients, regardless of mode of transportation, there was no correlation between OST and total miles travelled; although, there was a significant correlation between the time en route and distance, as well as total trip time and distance. CONCLUSIONS In this cohort of critically ill patients with hypoxemic respiratory failure, OST was over 40 minutes and was often longer than the total trip time. On-scene time did not correlate with mode of transport or distance traveled. These data can assist in planning inter-facility transports for both the sending and receiving hospitals, as well as CCT services.
