Background The American College of Surgeon (ACS), American Surgical Association (ASA), Association of Women Surgeons (AWS), and Society of Black Academic Surgeons (SBAS) partnered to gain insight into whether inequities found in surgical society presidents may be present earlier. Methods ACS, ASA, AWS, and SBAS presidents’ CVs were assessed for demographics and scholastic achievements at the time of first faculty appointment. Regression analyses controlling for age were performed to determine relative differences across societies. Results 66 of the 68 presidents’ CVs were received and assessed (97% response rate). 50% of AWS future presidents were hired as Instructors rather than Assistant professors, compared to 29.4% of SBAS, 25% of ASA and 29.4% of ACS. The future ACS, ASA, and SBAS presidents had more total publications than the AWS presidents, but similar numbers of 1st and Sr. author publications. Conclusion Gender inequities in academic surgeon hiring practices and perceived scholastic success may be present at first hire.

While the incidence of geriatric trauma continues to increase, outcomes following severe blunt liver injury (BLI) are unknown. We sought to investigate independent predictors of mortality among elderly trauma patients with severe BLI. A retrospective study of the NTDB (2014-15) identified patients with isolated, high-grade BLI. Patients were stratified into two groups, non-elderly (65 years) and elderly (≥65 years), and then two management groups: operative within 24 h of admission and non-operative. Demographics and outcomes were compared. Multivariable logistic regression was used to estimate association with mortality. A total of 1133 patients met our inclusion criteria. 107 patients required surgery and 1011 patients were managed non-operatively. Age was independently associated with mortality (AOR 1.04, p .001). For patients65 years, need for operative intervention was associated with a 55 times greater likelihood of death (AOR 55.1, p .001). In patients ≥65 years, operative intervention was associated with a 122 times greater likelihood of death (AOR 122.09, p = .005). Age is independently associated with mortality in patients with high grade BLI.

Describe the epidemiology of a large cohort of older adults with isolated traumatic brain injury (TBI) and identify predictors of mortality, palliative interventions, and discharge to preinjury residence in those presenting with moderate/severe TBI.Prospective observational study of geriatric patients with TBI enrolled across 45 trauma centers.Inclusion criteria were age ≥40 years, and computed tomography (CT)-verified TBI. Exclusion criteria were any other body region abbreviated injury scale score2 and presentation at enrolling center24 hours after injury.The analysis was restricted to individuals aged ≥65 and stratified into 3 age groups: young-old (65-74), middle-old (75-84), and oldest-old (≥85). Demographic, clinical, and injury data were collected. Predictors of mortality, palliative interventions, and discharge to preinjury residence in the moderate/severe TBI group were identified using Classification and Regression Tree and Generalized Linear Mixed Models.Of the 3081 subjects enrolled in the study, 2028 were ≥65 years old. Overall, 339 (16.7%) presented with a moderate/severe TBI and experienced a 64% mortality rate. A Glasgow Coma Scale (GCS) score9 was the main predictor of mortality, CT worsening (odds ratio [OR] = 1.7, P.04), cerebral edema (OR = 2.4, P.04), GCS9, and age ≥75 (OR = 2.1, P = .007) were predictors for palliative interventions, and an injury severity score ≤24 (OR = 0.087, P = .002) was associated with increased likelihood of discharge to preinjury residence in the moderate/severe TBI group.In this prospective study of a large cohort of older adults with isolated TBI, comparisons across the older age groups with moderate/severe TBI revealed that survival and favorable discharge disposition were influenced more by severity of injury rather than age itself. Indicating that chronological age alone maybe insufficient to accurately predict outcomes, and increased representation of older adults in TBI research to develop better diagnostic and prognostic tools is warranted.

Introduction The population and spatial characteristics of COVID-19 infections are poorly understood, but there is increasing evidence that in addition to individual clinical factors, demographic, socioeconomic and racial characteristics play an important role. Methods We analyzed positive COVID-19 testing results counts within New York City ZIP Code Tabulation Areas (ZCTA) with Bayesian hierarchical Poisson spatial models using integrated nested Laplace approximations. Results Spatial clustering accounted for approximately 32% of the variation in the data, with hot spots in all five boroughs. Spatial risk did not correspond precisely to population-based rates of positive tests. The strongest univariate association with positive testing rates was the proportion of residents in a ZIP Code Tabulation Area with Chronic Obstructive Pulmonary Disease (COPD). For every one unit increase in a scaled standardized measure of COPD in a community, there was an approximate 8-fold increase in the risk of a positive COVID-19 test in a ZCTA (Incidence Density Ratio = 8.2, 95% Credible Interval 3.7, 18.3). The next strongest association was with the proportion of Black and African American residents, for which there was a nearly five-fold increase in the risk of a positive COVID-19 test. (IDR = 4.8, 95% Cr I 2.4, 9.7). Increases in the proportion of residents older than 65, housing density and the proportion of residents with heart disease were each associated with an approximate doubling of risk. In a multivariable model including estimates for age, COPD, heart disease, housing density and Black/African American race, the only variables that remained associated with positive COVID-19 testing with a probability greater than chance were the proportion of Black/African American residents and proportion of older persons. Conclusions The population and spatial patterns of COVID-19 infections differ by race, age, physical environment and health status. Areas with large proportions of Black/African American residents are at markedly higher risk that is not fully explained by characteristics of the environment and pre-existing conditions in the population.

High school students are an important target audience for organ donation education. A novel educational intervention focused on Hispanic American (HA) high school students might improve organ donation rates.A prospective observational study was conducted in five Los Angeles High Schools with a high percentage of HA students. A "culturally sensitive" educational program was administered to students in grades 9 to 12. Preintervention surveys that assessed awareness, knowledge, perception, and beliefs regarding donation as well as the intent to become an organ donor were compared to postintervention surveys.A total of 10,146 high school students participated in the study. After exclusions, 4876 preintervention and 3182 postintervention surveys were analyzed. A significant increase in the overall knowledge, awareness, and beliefs regarding donation was observed after the intervention, as evidenced by a significant increase in the percentage of correct answers on the survey (41% pre- versus 44% postintervention, P.0001). When specifically examining HA students, there was a significant increase in the intent to donate organs (adjusted odds ratio 1.21, 95% confidence interval: 1.09, 1.34, P = .0003).This is the first study to demonstrate a significant increase in the intent to donate among HA high school students following an educational intervention.

Background Recent evidence supports the beneficial effect of alcohol on patients with traumatic brain injury (TBI). Pneumonia is a known complication following TBI; thus, the purpose of this study was to evaluate the effects of alcohol on pneumonia rates following moderate to severe TBI. Methods From 2005 to 2009, the Los Angeles County Trauma Database was queried for all patients ≥14 y of age with isolated moderate to severe TBI and admission serum alcohol levels. The incidence of pneumonia was compared between TBI patients with and without a positive blood alcohol concentration (BAC) level. The study population was then stratified into four BAC levels: None (0 mg/dL), low (0–100 mg/dL), moderate (100–230 mg/dL), and high (≥230 mg/dL). Pneumonia rates were compared across these levels. Results A total of 3547 patients with isolated, moderate to severe TBI were evaluated. Nearly 66% tested positive for alcohol. The pneumonia rate was significantly lower in the TBI patients who tested positive for alcohol (2.5%) compared with those who tested negative (4.0%, P = 0.017). The pneumonia rate also decreased across increasing BAC levels (linear trend P = 0.03). After logistic regression analysis, a positive ethanol (ETOH) level was associated with a reduced incidence of pneumonia (AOR = 0.62; 95%CI: 0.41–0.93; P = 0.020). Conclusion A positive serum alcohol level was associated with a significantly lower pneumonia rate in isolated, moderate to severe TBI patients. This may explain the observed mortality reduction in TBI patients who test positive for alcohol. Additional research is warranted to investigate the potential therapeutic implications of this association.

BACKGROUND: Traumatic brain injury (TBI) is the most common cause of death and disability in trauma patients, affecting over 1 million Americans per year. Minorities are at disproportionate risk for TBI, and they account for nearly half of all brain injury hospitalizations. Little is known regarding racial disparities in TBI patients. The objective of this study was to investigate the association of race on mortality in patients with moderate to severe isolated TBI. METHODS: The Los Angeles County Trauma System database, consisting of admissions from five Level I and eight Level II trauma centers, was queried for all patients with isolated moderate to severe TBI admitted between 1998 and 2005. Demographics and mortality were compared between races: Asian, African American, Hispanic, White, and Other. Multivariate logistic regression was used to determine the relationship between race and mortality. RESULTS: A total of 17,977 (23.8% female, 76.2% male) severe TBI patients were evaluated. Of this study population, 7.1% were Asian, 13.5% were African American, 42.3% were Hispanic, 32.5% were White, and 4.7% where classified as Other. Overall, Asians (adjusted Odds Ratio AOR 1.4; 95% CI: 1.14-1.71, P = 0.001) had a significantly higher risk in mortality when compared with Whites. Surprisingly, neither African Americans (AOR 1.02; 95% CI: 0.87-1.2, P = 0.82), nor Hispanics (AOR 1.00; 95% CI: 0.89-1.13, P > 0.9) were at increased risk of death compared to their White counterparts. CONCLUSION: This data supports the hypothesis that race may play a role in mortality in moderate to severe TBI. However, only Asians were at higher risk for death. Language: en

Background. Increasing data indicate treatment with β blockers might improve survival after traumatic brain injury (TBI); the optimal heart rate (HR) range for these patients is unknown. To guide treatment, admission HR in moderate to severe TBI patients was analyzed to determine if a specific range is associated with decreased mortality. Methods. The Los Angeles County Trauma System Database, consisting of five Level I and 8 Level II trauma centers, was queried for all injured patients admitted between 1998 and 2005 (n = 147,788). Isolated moderate to severe TBI patients (head abbreviated injury score ≥ 3) were then identified. Demographics and outcomes were compared at various admission HR subgroups ( < 50, 50―59, 60―69, 70―79, 80―89, 90―99, 100― 109, ≥110). Logistic regression was then performed to determine predictors of mortality. Results. After exclusions, a total of 11,977 isolated moderate to severe isolated TBI patients were analyzed, overall mortality was 11.5% with a trend toward lowest mortality at HR 80 to 89 (7.3%). Each HR subgroup had a significantly increased unadjusted odds ratio for mortality compared with HR 80 to 89, except HR 90 to 99 (OR 1.2, CI 1.0―1.5) and HR 100 to 109 (OR 1.2, CI 1.0―1.5). In multivariable logistic regression analysis, HR < 50, 50―59, 60―69, and ≥110 were independent predictors for increased mortality compared with HR 80―89. Conclusion. After isolated moderate to severe TBI, HR < 50, 50―59, 60―69, and ≥110 were independent predictors of increased mortality. HR outside the range 70―109 could serve as a marker for aggressive resuscitation. As mortality increased significantly with HR: < 50 (AOR 4.70), 50―59 (AOR 2.21), and 60―69 (AOR 1.63), our findings recommend avoiding HR < 70 in patients with moderate to severe TBI.

Emerging evidence suggests that male and female nervous systems respond differently to traumatic brain injury (TBI). The objective of this study was to examine outcomes between the sexes after TBI.A retrospective review of all severe TBI patients admitted between January and December 2005 was performed. Isolated severe TBI was defined as a head abbreviated injury score greater than 3 with an abbreviated injury score of 3 or less for other anatomic regions. The population was stratified into age subgroups (14 y, 14-44 y, 45-54 y, andor =55 y). Logistic regression was used to identify independent predictors of mortality.A total of 1,807 TBI patients were admitted. The mortality was significantly higher for women (43.2% vs 36.2%, P.01) with an adjusted odds ratio of 1.4 (95% confidence interval, 1.1-1.9, P.05). After stratification, only women age 55 and older had a significant difference in mortality (odds ratio, 1.71; 95% confidence interval, 1.11-2.62, P = .02).Female sex (particularly those ageor =55 y) is associated independently with higher mortality in isolated severe TBI. This increased mortality of postmenopausal women after isolated TBI may suggest a hormonal influence and warrants further investigation.
