A National Analysis of Racial and Sex Disparities Among Interhospital Transfers for Emergency General Surgery Patients and Associated Outcomes.

INTRODUCTION: Studies focusing on Emergency General Surgery (EGS) and Interhospital Transfer (IHT) and the association of race and sex and morbidity and mortality are yet to be conducted. We aim to investigate the association of race and sex and outcomes among IHT patients who underwent emergency general surgery. METHODS: A retrospective review of adult patients who were transferred prior to EGS procedures using the National Surgery Quality Improvement Project from 2014 to 2020. Multivariable logistic regression models were used to compare outcomes (readmission, major and minor postoperative complications, and reoperation) between interhospital transfer and direct admit patients and to investigate the association of race and sex for adverse outcomes for all EGS procedures. A secondary analysis was performed for each individual EGS procedure. RESULTS: Compared to patients transferred directly from home, IHT patients (n = 28,517) had higher odds of readmission [odds ratio (OR): 1.004, 95% confidence interval (CI) (1.002-1.006), P < 0.001], major complication [adjusted OR: 1.119, 95% CI (1.117-1.121), P < 0.001), minor complication [OR: 1.078, 95% CI (1.075-1.080), P < 0.001], and reoperation [OR: 1.014, 95% CI (1.013-1.015), P < 0.001]. In all EGS procedures, Black patients had greater odds of minor complication [OR 1.041, 95% CI (1.023-1.060), P < 0.001], Native Hawaiian and Pacific Islander patients had greater odds of readmission [OR 1.081, 95% CI (1.008-1.160), P = 0.030], while Asian and Hispanic patients had lower odds of adverse outcome, and female patients had greater odds of minor complication [OR 1.017, 95% CI (1.008-1.027), P < 0.001]. CONCLUSIONS: Procedure-specific racial and sex-related disparities exist in emergency general surgery patients who underwent interhospital transfer. Specific interventions should be implemented to address these disparities to improve the safety of emergency procedures.

A Narrative Review Investigating Practices and Disparities in Child Abuse Amongst United States Pediatric Trauma Patients & Associated Outcomes.

INTRODUCTION: Although non-accidental trauma continues to be a leading cause of morbidity and mortality among children in the United States, the underlying factors leading to NAT are not well characterized. We aim to review reporting practices, clinical outcomes, and associated disparities among pediatric trauma patients experiencing NAT. METHODS: A literature search utilizing PubMed, Google Scholar, EMBASE, ProQuest, and Cochrane was conducted from database inception until April 6, 2023. This review includes studies that assessed pediatric (age <18) trauma patients treated for NAT in the United States emergency departments. The evaluated outcome was in-hospital mortality rates stratified by race, age, sex, insurance status, and socioeconomic advantage. RESULTS: The literature search yielded 2641 initial articles, and after screening and applying inclusion and exclusion criteria, 15 articles remained. African American pediatric trauma patients diagnosed with NAT had higher mortality odds than white patients, even when adjusting for comparable injury severity. Children older than 12 mo experienced higher mortality rates compared to those younger than 12 mo, although some studies did not find a significant association between age and mortality. Uninsured insurance status was associated with the highest mortality rate, followed by Medicaid and private insurance. No significant association between sex and mortality or socioeconomic advantage and mortality was observed. CONCLUSIONS: Findings showed higher in-hospital mortality among African American pediatric trauma patients experiencing child abuse, and in patients 12 mo or older. Medicaid and uninsured pediatric patients faced higher mortality odds from their abuse compared to privately insured patients.

The Association Between Gender and Clinical Outcomes in Patients With Moderate to Severe Traumatic Brain Injury: A Systematic Review and Meta-Analysis.

INTRODUCTION: Traumatic brain injuries (TBIs) are a significant cause of morbidity and mortality in the United States. but have a disproportionate impact on patients based on gender. This systematic review and meta-analysis aim to compare gender differences in clinical outcomes between male and female adult trauma patients with moderate and severe TBI. METHODS: Studies assessing gender differences in outcomes following TBIs on PubMed, Google Scholar, EMBASE, and ProQuest were searched. Meta-analysis was performed for outcomes including in-hospital mortality, hospital length of stay, intensive care unit length of stay, and Glasgow outcome scale (GOS) at 6 mo. RESULTS: Eight studies were included for analysis with 26,408 female and 63,393 male patients. Meta-analysis demonstrated that males had a significantly lower risk of mortality than females (RR: 0.88; 95% CI 0.78, 0.99; P = 0.0001). Females had a shorter hospital length of stay (mean difference -1.4 d; 95% CI - 1.6 d, -1.2 d). No significant differences were identified in intensive care unit length of stay (mean difference -3.0 d; 95% CI -7.0 d, 1.1 d; P = 0.94) or GOS at 6 mo (mean difference 0.2 d; 95% CI -0.9 d, 1.4 d; P = 1). CONCLUSIONS: Compared to male patients, female patients with moderate and severe TBI had a significantly higher in-hospital mortality risk. There were no significant differences in long-term outcomes between genders based on GOS at 6 mo. These findings warrant further investigation into the etiology of these gender disparities and their impact on additional clinical outcome measures.

Enhancing safety & reducing fatalities in U.S. national parks: An evaluation of injury trends and policy implications in the ten most visited parks.

INTRODUCTION: National parks in the United States experience a significant number of annual visits, and with increasing popularity, injuries are expected to rise. This study aims to assess fatal injuries in the top ten most visited U.S. national parks from 2013 to 2022 to improve current policies and develop effective prevention strategies. METHODS: A cross-sectional study was conducted using public National Park Service data. Data including visitor demographics, injury cause, and location, were collected. Fatal injuries were categorized by season, age group, and gender. RESULTS: Summer had the highest total number of fatal injuries. The winter season had the highest rate of fatal injuries per 10 million visitors. The number of fatal injuries per 10 million visitors decreased from 2013 to 2022 for most parks. The South Region reported the highest total number of fatalities. The West Region demonstrated higher rates when adjusted for visitor volume. Fatal injuries were most prevalent in the 35-44 age group, followed by the 15-24 and 25-34 age groups, with the least incidents in the 0-14 age group, and were more common among males (71.5 % of total injuries). CONCLUSION: This study found the highest number of total injuries occurring in summer; however, winter presented a higher risk per visitor. Slips and falls were the most common cause of injuries, requiring targeted safety measures. Males in the 35-44 age group reported the highest fatality rates. These findings highlight the necessity for improved monitoring and reporting to better understand injury causes and formulate specific, evidence-based policies for prevention.

Evaluating Mortality Outcomes, Transfusion Characteristics, and Risk Factors Associated With Cirrhotic Trauma Patients Undergoing Emergency Laparotomy Versus Non-Operative Management: A National Analysis.

BACKGROUND: Patients with liver cirrhosis (LC) demonstrate significantly elevated mortality rates following a traumatic event. This study aims to examine and compare the clinical outcomes in adult trauma patients with pre-existing LC undergoing laparotomy or non-operative management (NOM). Additionally, the study aims to investigate various patient outcomes, including mortality rate based on transfusion needs and timing. METHODS: This retrospective cohort study utilized the American College of Surgeons Trauma Quality Program Participant Use File (ACS-TQIP-PUF) 2017-21 to compare laparotomy vs NOM in adults (≥18 years) with pre-existing LC who presented to trauma facilities with isolated blunt solid organ abdominal injuries (Injury Severity Score ≥16, Abbreviated Injury Scale solid organ abdomen ≥3). RESULTS: Among 929 patients, 38.2% underwent laparotomy, while 61.7% received NOM. The in-hospital mortality rate was lower for patients who received NOM (52.3% vs 20.0%, P < .01). The risk of in-hospital mortality was significantly associated with laparotomy (OR 5.22, 95% CI: 2.06-13.18, P < .01) and sepsis (OR 99.50, 95% CI: 6.99-1415.28, P < .01). On average an increase in blood units in 4 hours was observed among those who experienced an in-hospital mortality (OR 5.65, 95% CI: 3.05-8.24, P < .01) and those who underwent laparotomy (OR 3.85, 95% CI: 1.36-6.34, P < .01). CONCLUSION: Trauma patients with moderate to severe isolated organ injury and Liver cirrhosis had significantly higher mortality rates, acute renal failure, whole blood units received, as well as longer ICU-LOS when undergoing laparotomy compared to non-operative management.

Profiling antibody epitopes induced by mRNA-1273 vaccination and boosters.

Background: Characterizing the antibody epitope profiles of messenger RNA (mRNA)-based vaccines against SARS-CoV-2 can aid in elucidating the mechanisms underlying the antibody-mediated immune responses elicited by these vaccines. Methods: This study investigated the distinct antibody epitopes toward the SARS-CoV-2 spike (S) protein targeted after a two-dose primary series of mRNA-1273 followed by a booster dose of mRNA-1273 or a variant-updated vaccine among serum samples from clinical trial adult participants. Results: Multiple S-specific epitopes were targeted after primary vaccination; while signal decreased over time, a booster dose after >6 months largely revived waning antibody signals. Epitope identity also changed after booster vaccination in some subjects, with four new S-specific epitopes detected with stronger signals after boosting than with primary vaccination. Notably, the strength of antibody responses after booster vaccination differed by the exact vaccine formulation, with variant-updated mRNA-1273.211 and mRNA-1273.617.2 booster formulations inducing significantly stronger S-specific signals than a mRNA-1273 booster. Conclusion: Overall, these results identify key S-specific epitopes targeted by antibodies induced by mRNA-1273 primary and variant-updated booster vaccination.

Estabilidad del aceite de hígado de tiburón microencapsulado vs. pool de aceite / Stability of microencapsulated shark liver oil vs pool oil

El estudio de estabilidad del aceite microencapsulado y sin microencapsular se realizó por el método de vida de estante a las temperaturas de 2-8 °C, y temperatura ambiente, respectivamente, durante doce meses. Los parámetros analizados al pool de aceite fueron: características organolépticas, índice de acidez, peróxido, saponificación, contenido de vitamina A y conteo microbiológico. Mientras que al aceite microencapsulado se le evaluaron las características organolépticas, la eficiencia de encapsulación, contenido de humedad, aceite superficial, contenido de vitamina A y conteo microbiológico. Los resultados evidenciaron una disminución superior al 5% en el contenido de vitamina A en el aceite sin microencapsular, a diferencia del aceite microencapsulado. Se logró el enmascaramiento del olor intenso a pescado, y los restantes parámetros evaluados se encontraron dentro de los límites establecidos. El aceite de hígado de tiburón microencapsulado resultó estable física, química y microbiológicamente por doce meses, mientras que el aceite sin microencapsular solo seis meses. El proceso de microencapsulación no solo mejoró sus características organolépticas, sino también favoreció su estabilidad lográndose un mayor período de vida útil.

A stability study was carried out for microencapsulated and non-microencapsulated oil by applying the shelf-life method at temperature ranges of 2 to 8 °C, and ambient temperature, respectively, for a period of 12 months. The analyzed parameters in the case of pool oil were: organoleptic characteristics, acidity index, peroxide, saponification, vitamin-A content and microbiological count. For microencapsulated oil, the following parameters were evaluated: organoleptic characteristics, capsulation efficiency, humidity content, superficial oil, vitamin-A content and microbiological count. The stability study for non-microencapsulated oil proved that there was a decrease of over 5% in vitamin-A content, when compared to microencapsulated oil. The intense fish smell was properly masked and the remaining evaluated parameters were within established limits. Microencapsulated shark liver oil turned out to be physically, chemically and microbiologically stable for a period of 12 months, while non-microencapsulated oil remained stable for only 6 months. The microencapsulation process not only improved the oil´s organoleptic characteristics, but it also made it more stable, allowing for a longer shelf life.
