Multicenter Study of Perioperative Hepatic Angioembolization as an Adjunct for Management of Major Operative Hepatic Trauma.

BACKGROUND: The management of major liver trauma continues to evolve in trauma centers across the US with increasing use of minimally invasive techniques. Data on the outcomes of these procedures remain minimal. The objective of this study was to evaluate patient complications after perioperative hepatic angioembolization as an adjunct to management of major operative liver trauma. STUDY DESIGN: A retrospective multi-institutional study was performed at 13 level 1 and level 2 trauma centers from 2012 to 2021. Adult patients with major liver trauma (grade 3 and higher) requiring operative management were enrolled. Patients were divided into 2 groups: angioembolization (AE) and no angioembolization (NO AE). Univariate and multivariate analyses were performed. RESULTS: A total of 442 patients were included with AE performed in 20.4% (n = 90 of 442) of patients. The AE group was associated with higher rates of biloma formation (p = 0.0007), intra-abdominal abscess (p = 0.04), pneumonia (p = 0.006), deep vein thrombosis (p = 0.0004), acute renal failure (p = 0.004), and acute respiratory distress syndrome (p = 0.0003), and it had longer ICU and hospital length of stay (p < 0.0001). On multivariate analysis, the AE had a significantly higher amount intra-abdominal abscess formation (odds ratio 1.9, 95% CI 1.01 to 3.6, p = 0.05). CONCLUSIONS: This is one of the first multicenter studies comparing AE in specifically operative high-grade liver injuries and found that patients with liver injury that undergo AE in addition to surgery have higher rates of both intra- and extra-abdominal complications. This provides important information that can guide clinical management.

Angiotensin II: A Review of Current Literature.

Up to one-third of all patients admitted to intensive care units carry a diagnosis of shock. The use of angiotensin II is becoming widespread in all forms of shock, including cardiogenic, after the U.S. Food and Drug Administration's (FDA's) initial approval for vasoplegic shock in 2017. Here, the authors review the literature on angiotensin II's mechanism of action, benefits, and future therapeutic opportunities.

When Is It Safe to Start Pharmacologic Venous Thromboembolism Prophylaxis After Pelvic Fractures? A Prospective Study From a Level I Trauma Center.

BACKGROUND: The ideal time for pharmacologic venous thromboembolism (VTE) prophylaxis initiation after pelvic fracture is controversial. This prospective study evaluated the safety and efficacy of early VTE prophylaxis after blunt pelvic trauma. METHODS: Patients presenting to our American College of Surgeons-verified level I trauma center (between December 1, 2016 and November 30, 2017) with blunt pelvic fracture were prospectively screened. Exclusion criteria were emergency department death, immediate operative intervention, transfers, home anticoagulation, pregnancy, and patients receiving no pharmacologic VTE prophylaxis during hospitalization. Patients were dichotomized into study groups based on VTE prophylaxis initiation time ≤48 h (early prophylaxis [EP]) versus >48 h (late prophylaxis [LP]) after emergency department arrival. Demographics, injury data, clinical data, VTE prophylaxis agent and initiation time, and outcomes were compared. RESULTS: After exclusions, 146 patients were identified: 74 (51%) patients in EP group and 72 (49%) patients in LP group. Pelvic fracture severity was comparable between groups (Abbreviated Injury Scale extremity score 2 [2-3] versus 2 [2-3]; P = 0.610). On univariate analysis, deep vein thrombosis rates were higher after LP (n = 5, 7% versus 0, 0%; P = 0.027). Pulmonary embolism rates were similar (n = 2, 3% versus n = 3, 4%; P = 1.000). No patient required delayed intervention for bleeding, and postprophylaxis blood transfusion was comparable between groups (P > 0.05). On multivariate analysis, timing of pharmacologic VTE prophylaxis initiation was not associated with VTE development (odds ratio, 0.647; P = 0.999). Pelvic angioembolization was independently associated with VTE (odds ratio, 1.296; P = 0.044). CONCLUSIONS: Early initiation of pharmacologic VTE prophylaxis after blunt pelvic fracture is safe. Although EP initiation did not reduce the rate of VTE, these data identify angioembolization as an independent risk factor for VTE. Patients with blunt pelvic fracture who undergo angioembolization may therefore represent a high-risk population who may especially benefit from EP.

Effect of Interhospital ICU Relocation on Patient Physiology and Clinical Outcomes.

Relocation of large numbers of critically ill patients between hospitals is sometimes necessary and the risks associated with relocation may be high. In the setting of adherence to an interhospital intensive care unit (ICU) relocation protocol, we aimed to determine whether the interhospital relocation of all ICU patients in a single day is associated with changes in vital signs, device removal, and worse clinical outcomes. We conducted a prospective, observational, cohort study of all critically ill adults admitted to a tertiary medical center's ICUs on the day of a planned hospital relocation and exposed to interhospital ICU relocation compared with unexposed critically ill adults. Changes in vital signs were evaluated by the before-and-after interhospital relocation measurement of vital signs, and clinical outcomes were collected for all patients. A total of 699 patients were admitted to the ICU during the observation period, 24 of whom were exposed to interhospital ICU relocation on a single day. The median interhospital transport duration was 28 minutes (interquartile range: 24-35) and 29% of patients were receiving invasive mechanical ventilation. Patients exposed to interhospital ICU relocation had no significant change in any vital sign measurement and no devices were unintentionally removed. Inhospital mortality was similar (8.3%) to patients not exposed to interhospital ICU relocation (9.2%, P > .99). In the setting of adherence to an ICU relocation protocol, the interhospital ICU relocation of all critically ill adults during a single day is not associated with changes in vital signs, device removal, or worse clinical outcomes.

Selective versus nonselective embolization versus no embolization in pelvic trauma: A multicenter retrospective cohort study.

BACKGROUND: Traumatic hemorrhage from pelvic fractures is a significant challenge, and angioembolization has become standard. Optimal treatment is undefined in two clinical scenarios. The first is in the presence of a negative angiogram. Can arterial embolization treat venous bleeding by decreasing the arterial pressure head? If the angiogram is positive, is nonselective embolization (NSE) or selective embolization (SE) better? The purpose of this study is to determine if embolization after a negative angiogram aids in hemorrhage control and when the angiogram is positive, which level of embolization is superior? METHODS: A multicenter retrospective review was conducted including blunt trauma patients with pelvic fractures who underwent angiography. Demographic and clinical data were compiled on all subjects. NSE refers to an intervention at the level of the internal iliac artery and SE is defined as any distal intervention. Theoretical complications of pelvic embolization are those thought to arise from decreased pelvic blood flow and will be referred to as embolization-related complications. Thromboembolic complications included deep vein thrombosis or pulmonary embolism. RESULTS: One hundred ninety-four patients met inclusion criteria. Of the 67 patients with a negative angiogram, 26 (38.8%) were embolized. In those patients requiring transfusion, the units given in the first 24 hours were decreased in the embolization group (7.5 vs. 4.0, p = 0.054). Embolization-related complications occurred more frequently in those not embolized (11.4% vs. 6.0%, p = 0.414).One hundred forty-five patients were embolized, 99 (68.3%) NSE and 46 (31.7%) SE. There were no significant differences in mortality or transfusion requirements. There was no difference in the rate of embolization-related complications (4.1% vs. 2.1%, p = 0.352). There was a significantly increased rate of thromboembolic complications in the NSE group (12.1% vs. 0, p = 0.010). CONCLUSION: Embolization in the face of a negative angiogram may aid in hemorrhage control for those patients being actively transfused. If embolized, then selective occlusion of more distal vessels rather than of the main internal iliac artery should be performed. LEVEL OF EVIDENCE: Therapeutic, level IV.

Reproductive Life Plan Counseling and Effective Contraceptive Use among Urban Women Utilizing Title X Services.

BACKGROUND: Although the Centers for Disease Control and Prevention and the U.S. Office of Population Affairs recommend inclusion of reproductive life plan counseling (RLPC) in all well-woman health care visits, no studies have examined the effect of RLPC sessions on the decision to use effective contraception at publicly funded family planning sites. RLPC could be a particularly impactful intervention for disadvantaged social groups who are less likely to use the most effective contraceptive methods. METHODS: Using data from 771 nonpregnant, non-pregnancy-seeking women receiving gynecological services in the Cincinnati-Hamilton County Reproductive Health and Wellness Program, multinomial logistic regression models compared users of nonmedical/no method with users of 1) the pill, patch, or ring, 2) depot medroxyprogesterone acetate, and 3) long-acting reversible contraception (LARC). The effect of RLPC on the use of each form of contraception, and whether it mediated the effect of race/ethnicity and education on contraceptive use, was examined while controlling for age, insurance status, and birth history. The interaction between RLPC and race/ethnicity and the interaction between RLPC and educational attainment was also assessed. FINDINGS: RLPC was not associated with contraceptive use. The data suggested that RLPC may increase LARC use over nonmedical/no method use. RLPC did not mediate or moderate the effect of race/ethnicity or educational attainment on contraceptive use in any comparison. CONCLUSIONS: In this system of publicly funded family planning clinics, RLPC seems not to encourage effective method use, providing no support for the efficacy of the RLPC intervention. The results suggest that this intervention requires further development and evaluation.

Not all mechanisms are created equal: a single-center experience with the national guidelines for field triage of injured patients.

BACKGROUND: Trauma systems use prehospital evaluation of anatomic and physiologic criteria and mechanism of injury (MOI) to determine trauma center need (TCN). MOI criteria are established nationally in a collaborative effort between the Centers for Disease Control and Prevention and the American College of Surgeons' Committee on Trauma and have been revised several times, most recently in 2011. Controversy exists as to which MOI criteria truly predict TCN. We review our single-center experience with past and present National Trauma Triage Criteria to determine which MOI predict TCN. METHODS: The trauma registry of an urban Level I trauma center was reviewed from 2001 to 2011 for all patients meeting only MOI criteria. Patients meeting any anatomic and physiologic criteria were excluded. TCN was defined as death, Injury Severity Score (ISS) of greater than 15, emergency department transfusion, intensive care unit admission, need for laparotomy/thoracotomy/vascular surgery within 24 hours of arrival, pelvic fracture, 2 or more proximal long bone fractures, or neurosurgical intervention during admission. Logistic regression analysis was used to identify which MOI predict TCN. RESULTS: A total of 3,569 patients were transported to our trauma center who met only MOI criteria and had the MOI recorded in the registry; 821 MOI patients (23%) were identified who met our definition of TCN. Significant predictors of TCN included death in the same passenger compartment, ejection from vehicle, extrication time of more than 20 minutes, fall from more than 20 feet, and pedestrian thrown/runover. Criteria not meeting TCN include vehicle intrusion, rollover motor vehicle collision, speed of more than 40 mph, injury from autopedestrian/autobicycle of more than 5 mph, and both of the motorcycle crash (MCC) criteria. CONCLUSION: With the exception of vehicle intrusion and MCC, the new National Trauma Triage Criteria accurately predicts TCN. In addition, extrication time of more than 20 minutes was a positive predictor of TCN in our system. Elimination of the vehicle intrusion and MCC criteria and reevaluation of extrication time merits further study.

The drugs-violence nexus among rural felony probationers.

Little research has focused on the drugs-violence nexus in rural areas. As such, the purpose of this study is to use Goldstein's tripartite conceptual framework to examine the relationship between drugs and violence among felony probationers in rural Appalachian Kentucky (n = 799). Data on demographics, substance use criminal history, and violence were collected between 2001 and 2004 using an interviewer-administered questionnaire. Rural probationers are partitioned into four groups based on lifetime violent victimization/perpetration experiences: (a) neither a perpetrator nor a victim, (b) perpetrator only, (c) victim only, and (d) both a perpetrator and a victim. Chi-square analyses indicate substance use, and criminal history varies across the four groups. Binary logistic regression analyses are used to explore the significant correlates of both perpetration and victimization. Multivariate analyses support both the psychopharmacological model and the economic compulsive models of perpetration and victimization. Further implications of these findings are discussed.

Racial differences in HIV/AIDS discussion strategies and sexual risk behaviors among drug-abusing female criminal offenders.

African-American female inmates are disproportionately affected by the human immunodeficiency virus (HIV), with heterosexual contact as the primary mode of transmission. This could be the result of racial differences in the strategies used by women to persuade a potential sexual partner to discuss HIV/AIDS and engage in condom use. Data were collected from 336 female inmates as part of the Reducing Risky Relationships for HIV (RRR-HIV) protocol within the Criminal Justice Drug Abuse Treatment Studies (CJ-DATS) cooperative agreement. Bivariate analyses indicated that African-American drug-using women were more likely than Whites to use the rational, withdrawal, and persistence approaches to discuss HIV/AIDS with a sexual partner. Negative binomial regression models were used to identify which interpersonal discussion strategies were significant correlates of the number of the times White and African-American participants had unprotected vaginal sex in the 30 days before incarceration. Results from the multivariate model indicate that White women who are more likely to use the rational discussion strategy were 15% less likely to engage in unprotected vaginal sex; however, these findings were not replicated in the African-American sample. Findings add to the literature on racial differences in HIV/AIDS discussion strategies and sexual risk behaviors among drug-abusing female criminal offenders.
