Relationship between trauma center patient volume (TCV) and mortality remains inconclusive. Our aim was to determine the relationship between TCVs and observed/expected (O/E) all-cause mortality. This is the first study to evaluate the relationship between trauma center (TC) volumes and O/E all-cause mortality with no exclusion. Review of prospectively collected data from 94 TCs using the National Sample Program from the National Trauma Data Bank 2013. TCs were stratified into five groups based on TCV: <701, 701 to 1200, 1201 to 1700, 1701 to 2200, and >2200 yearly patient encounters. Chi-square and coefficient of determination were used for data analysis with a statistical significance defined as P-value < 0.05. A total of 139,324 trauma patients with blunt and penetrating injuries were evaluated from the National Sample Program. Of which, 63.6 per cent were male, 70.6 per cent white, and the average age was 41 years. The data were stratified by TCV into five groups with average O/Es ranging from 0.69 to 0.86 (P > 0.05). The coefficient of determination between TCV and O/E was r = 0.14 and r2 = 0.02. When controlling for Injury Severity Score, the correlation between mechanism of injury (blunt vs penetrating) and O/E mortality was r = 20.025. The group with the lowest average volumes had statistically significantly worse outcomes than the group with next higher volumes and also worse than the group with the highest volumes (Group 5, P = 0.04). Higher TC volumes correlated with higher injury severity and lower O/E mortality.

The object of the study is the digital competitiveness of the country and its impact on GDP. The paper summarizes the methodology for determining the rating of global digital competitiveness and investigates the impact of digital competitiveness on GDP using econometric analysis methods. The methodological basis of the study was the fundamental principles of economic theory, statistics and econometrics. To develop a statistical model of the relationship between digital competitiveness and GDP, correlation analysis was performed using the pairwise regression equation, and to influence individual factors - a linear multiple regression equation. The parameters of the constructed models by the method of least squares are estimated and their statistical significance is checked. The results of the study show that there is a close inverse relationship between the rating on the Digital Competitiveness Index and GDP. This is due to the fact that the linear correlation coefficient is -0.819, and the value of the coefficient of determination (0.6712) shows the decisive influence of digital competitiveness on GDP. Verification of the statistical significance of the constructed model allowed to recognize it as statistically reliable, which allows to use it for forecasting. Instead, the resulting econometric model of the relationship between individual factors of digital competitiveness rating and GDP is characterized by a strong inverse relationship between the two factors "Knowledge" and "Technology" and a direct relationship between the factor "Readiness for the future". The factor of "Knowledge", which characterizes the process of digital transformation of Ukraine through understanding, studying and creating new technologies, has a decisive influence on the volume of GDP. The developed model of the relationship between individual factors of digital competitiveness rating and GDP, as adequate and statistically significant, can be used for further analysis and forecasting. It is proved that the process of digitalization is an urgent need for the existence of the economic system at present, namely the introduction of digital technologies can increase the competitiveness of the country on the world stage.

Abstract Introduction Burn camps provide a unique environment and activities for children that have experienced a burn-injury. Positive outcomes from attending burn camp include increased self-esteem, decreased feelings of isolation and a greater sense of self-confidence. In a 3-year retrospective review of camper evaluations from one of the largest and longest running week-long burn camps in the nation for ages 5–17, we aimed to assess if a child’s gender, age, TBSA or ethnicity affected the impact that burn camp had on a child. Methods A 3-year retrospective review of a Burn Camp’s camper evaluation forms was conducted for campers that attended burn camp between 2017–2019. Camp rosters were reviewed to determine the camper gender, age, TBSA and ethnicity. Camper self-evaluation forms completed at the end of each camp session were reviewed to record camper responses to questions regarding their opinions on the impact camp had on them as well as how camp will impact their lives once they return home. Categorical variables were summarized as frequency and percentage, and continuous variables were described as median and range. To check the relationship between two categorical variables, Chi-square test was used. To compare the continuous variable among groups, Kruskal-Wallis ANOVA was used. Statistical significance was declared based on a p value&lt; 0.5. Results Within 2017–2019, there were 413 camper records. Participants’ demographic characteristics are summarized in Table 1. There were 208 males (50.3%) and 205 females (49.6%). The median age of campers were 11.86, 12.44 and 12.45 for 2017–2019, with the range from 5.16 years to 17.96 years. The median TBSA were 20, 20 and 18 for 2017–2019, with the range from 0.08 to 90. Collectively there were 47.7% Hispanic (n= 197); 24.2% Whites (n=100); 13.1% Black (n= 54); 4.6% Asian (n=19) and 7.7% Other (n=32). There were 395 camper self-evaluation forms submitted. Results of three questions there we were interested in are summarized collectively in Table 2. 57% of campers responded, “Yes, Definitely” to the question “After going to this event, will you feel more comfortable being around your classmates or friends?” 54% responded, “ Yes, Definitely” to the question “Do you feel more confidents in sharing your burn story with others when returning home?” and 51% responded “Yes, Definitely” to “Did you learn anything that will help you when you return home?” Conclusions In analyzing the camper responses, there was no statistically significant difference in responses comparing gender, age, TBSA or ethnicity.

BackgroundPositive serology for cytomegalovirus (CMV) has been associated with all-cause mortality risk but its role in COPD mortality is unknown. The objective of the present study was to assess the relationship between CMV serology and COPD mortality.MethodsWe analysed data from 806 participants in the Tucson Epidemiological Study of Airway Obstructive Disease who, at enrolment, were aged 28–70 years and had completed lung function tests. We tested CMV serology in sera from enrolment and defined “high CMV serology” as being in the highest tertile. Vital status, date and cause of death were assessed through death certificates and/or linkage with the National Death Index up to January 2017. The association of CMV serology with all-cause and cause-specific mortality risk was tested in Cox models adjusted for age, sex, level of education, body mass index, smoking status and pack-years.ResultsHigh CMV serology was marginally associated with all-cause mortality (p=0.071) but the effect was inversely dependent on age, with the association being much stronger among participants <55 years than among participants ≥55 years at enrolment (p-value for CMV-by-age interaction <0.001). Compared with low CMV serology, high CMV serology was associated with mortality from COPD among all subjects (adjusted hazard ratio (HR) 2.38, 95% CI 1.11–5.08; p=0.025) and particularly in subjects <55 years old at enrolment (HR 5.40, 95% CI 1.73–16.9; p=0.004). Consistent with these results, high CMV serology also predicted mortality risk among subjects who already had airflow limitation at enrolment (HR 2.10, 95% CI 1.20–3.68; p=0.009).ConclusionsWe report a strong relationship between CMV serology and the risk of dying from COPD, and thus identify a novel risk factor for COPD mortality.

Purpose: To analyze the feasibility and outcomes of robotic rectal cancer surgery in obese patients. Methods: From 2005 to 2012, 101 consecutive rectal cancers operated robotically were enrolled in a prospective database. Patients were stratified into obese (BMI ≥ 30 kg/m2) and non-obese (BMI < 30 kg/m2) groups. Operative, perioperative parameters, and pathologic outcomes were compared. Data were analyzed using SPSS 22.0, while statistical significance was defined as a p value ≤ .05. Results: There were 33 obese patients (mean BMI 33.8 kg/m2). Patients were comparable regarding gender, T stage, and type of operation. Operative time and blood loss were higher in the obese group; only operative time was statistically significant. The conversion rate, length of stay, and anastomotic leak rates were similar. Circumferential margin positivity and lymph node yield were comparable. Disease free and overall survivals at 3 years were 75.8% versus 80.9% and 84.8% versus 92.6%, respectively for obese and non-obese subgroups. Conclusions: Robotic surgery for curative treatment of rectal cancer in the obese is safe and feasible. BMI does not influence conversion rates, length of stay, postoperative complications, and quality of the specimen or survival when the robotic platform is used.

Abstract We have previously demonstrated significant interpatient variability in the IC50imatinib, a measure of the intrinsic sensitivity of a patient to imatinib induced kinase inhibition. Furthermore, this measure is predictive of the achievement of major molecular response (MMR &gt; 3 log reduction in BCR-ABL) in de-novo CML patients treated with imatinib (n=60)1. In an expanded patient pool (n=116) we now perform an evaluation of the IC50 as a predictor of response, and address the IC50imatinib as a guide to dose selection. Samples were obtained with informed consent from de novo CML patients enrolled to either the TIDEL (600mg imatinib) or TOPS (randomised 400mg vs 800mg imatinib) trials. Blood was collected pre therapy, and the IC50 was performed as previously1. Outcome data was assessed using Kaplan Meier Analysis and the log rank test was used to assess statistical significance. In our previous analysis the IC50imatinib was divided about the median value for the cohort (0.6μM) into low and high IC50, with a significantly greater proportion of patients with low IC50imatinib achieving MMR by 12 months. In this expanded patient pool, we confirm this finding (&lt;median of 0.7μM for this patient group) (low IC50 65% of patients achieve MMR by 12 mo vs high IC50 39% of patients p=0.014) Dividing the IC50’s into quartiles we now demonstrate that the IC50imatinib is a continuous variable with a greater proportion of patients in the lower quartile achieving MMR than those in the higher (Table 1 Total). Addressing the issue of dose we demonstrate that no patients with IC50&gt;0.95uM achieve MMR on 400mg, and that this is statistically significantly when compared to all other groups. At 600mg while there is no overall significant difference there is a statistically relevant difference between groups 1, 2 and 4 as indicated. In contrast, at 800 mg the effect of IC50imatinib is overcome. MMR by 12 months Total 400mg 600mg 800mg p value Group1 &lt;0.5μM 67% (27) 83% (12)* 50% (8)* 86% (7) 0.470 Group 2 &gt;0.5&lt;0.7μM 63% (30) 67% (6)* 53% (17)* 71% (7) 0.337 Group 3 &gt;0.7&lt;0.95μM 45% (31) 40%(5)* 30% (10) 56% (16) 0.139 Group 4&gt;0.95μM 32% (28) 0% (7)* 22% (9)* 58% (12) 0.016 P value 0.042 0.018 0.108 0.778 Table 1: Dividing the patients into quartile based on the IC50 imatinib and assessing the Impact of dose on the achievement of MMR by 12 month. *p value &lt;0.05 between groups (n). The failure to achieve a Complete Cytogenetic Response by 12 months is considered a suboptimal response. Assessing the molecular equivalent (≥2 log reduction in BCR-ABL) we demonstrate that a significantly greater proportion of patients with IC50imatinib&gt;0.7μM fail to achieve a 2 log reduction when treated with 400mg (IC50 &lt;0.7μM 11%: &gt;0.7μM 33% p=0.034), and 600mg (IC50 &lt;0.7μM 12%: &gt;0.7μM 22% p=0.036). However, there is no significant difference in the 800mg patient cohort (IC50 &lt;0.7μM 7%: &gt;0.7μM 14% p=0.79). This analysis confirms that the IC50imatinib, is predictive of imatinib response. Patients with an IC50imatinib &lt;0.7μM are likely to respond well to doses of 400mg imatinib, as suggested by evaluation of statistically relevant outcome benefit. In contrast patients with higher IC50imatinib (&gt;0.7μM) may benefit from higher dosing regimens (p=0.012). Thus, the accurate assessment of IC50imatinib could support dose optimization strategy for patients with a suboptimal response.
