OBJECTIVE To evaluate ED treatment of these patients, to document their outcomes, and to identify risk factors associated with death. METHODS A retrospective cohort study was performed on active cancer patients presenting with deep venous thrombosis or pulmonary embolism to two academic EDs between July 2012 and June 2016. Key outcomes included mortality, ED revisit, and admission within 30 days. The patient cohort was characterized; crosstabs and regression analysis were performed to assess relative risks (RRs) and mitigating factors associated with 30-day mortality. RESULTS Of 355 patients, 9% died and 38% had one or more ED revisits or admissions. Recent immobility (RR 2.341, 95% CI 1.227-4.465), poor functional status (RR 2.090, 95% CI 1.028-4.248), recent admission (RR 2.441, 95% CI 1.276-4.669), and metastatic cancer (RR 4.669, 95% CI 1.456-14.979) were major risk factors for mortality. ED-provided anticoagulation reduced the overall mortality risk (RR 0.274, 95% CI 0.146-0.515) and mitigated the risk from recent immobility (RR 1.250, 95% CI 0.462-3.381), especially among patients with good or fair functional status. CONCLUSION Immobility and cancer morbidity are key risk factors for mortality after an acute VTE, but ED-provided anticoagulation mitigates the risk of immobility among healthier patients. Eastern Cooperative Oncology Group performance status can help clinicians risk stratify these patients at presentation.

It receives approximately 30% of the resting cardiac output by way of the portal vein and the hepatic artery. The liver can be affected by a variety of disorders, and because of its varied synthetic and metabolic functions, liver disease may manifest with a broad range of clinical signs and symptoms. Acute and chronic diseases of the liver are common in the general population and represent a common cause for presentation to the emergency department (ED).

To date, however, there have been few studies to assist program directors in determining which pre-residency variables best predict performance during EM residency. To evaluate which pre-residency variables best correlated with an applicant's performance during residency. This was a retrospective multicenter sample of all residents in the three most recent graduating classes from nine participating EM residency programs. The outcome measure of top residency performance was defined as placement in the top third of a resident's graduating class based on performance on the final semi-annual evaluation. A total of 277 residents from nine institutions were evaluated. Eight of the predictors analyzed had a significant correlation with the outcome of resident performance. Applicants' grade during home and away EM rotations, designation as Alpha Omega Alpha (AOA), U.S. Medical Licensing Examination (USMLE) Step 1 score, interview scores, "global rating" and "competitiveness" on nonprogram leadership standardized letter of recommendation (SLOR), and having five or more publications or presentations showed a significant association with residency performance. We identified several predictors of top performers in EM residency: an honors grade for an EM rotation, USMLE Step 1 score, AOA designation, interview score, high SLOR rankings from nonprogram leadership, and completion of five or more presentations and publications. EM program directors may consider utilizing these variables during the match process to choose applicants who have the highest chance of top performance during residency.

Without their generous contributions of time and expertise to the peer-review process, the Journal would not be able to advance its mission of emphasizing practical, efficient, and world-class emergency care. The top section editors and reviewers are chosen based on their quality of work, number of assignments, and timeliness of reviews.

Recent studies indicate that bandemia is highly predictive of a serious infection, suggesting that clinicians who do not appreciate the value of band counts may delay diagnosis or overlook severe infections. Whereas previous studies focused on determining the quantitative value of the band count (ie, determining sensitivity, threshold for bandemia, etc.), this study directs attention to patient-centered outcomes, hypothesizing that the degree of bandemia predisposes patients to subsequent negative clinical outcomes associated with underappreciated severe infections. This retrospective study of electronic medical records includes patients who initially presented to the emergency department (ED) with bandemia and were subsequently discharged from the ED. These patients were screened for repeat ED visits within 7 days and death within 30 days. In patients with severe bandemia who were discharged from the ED, there was a 20.9% revisit rate at 7 days and a 4.9% mortality rate at 30 days, placing severely bandemic patients at 5 times significantly greater mortality compared to nonbandemic patients (P = .032). Our review of patient outcomes suggests that the degree of bandemia, especially in the setting of concurrent tachycardia or fever, is associated with greater likelihood of negative clinical outcomes.

However, there is no evidence supporting the optimal time or duration for an EM rotation, and a number of institutions offer third-year rotations. A recently published syllabus provides areas of knowledge, skills, and attitudes that third-year EM rotation directors can use to develop curricula. This article expands on that syllabus by providing a comprehensive curricular guide for the third-year medical student rotation with a focus on implementation. Included are consensus-derived learning objectives, discussion of educational methods, considerations for implementation, and information on feedback and evaluation as proposed by the Clerkship Directors in Emergency Medicine Third-Year Curriculum Work Group.

The EM OCP provides the representation of the practice of emergency medicine, yet we do not know the current level of effectiveness of its instruction. We aimed to document medical student perceptions and expectations of the instruction of the EM OCP. We surveyed medical students from five institutions after their emergency medicine clerkship on their instruction of the EM OCP. Analysis included univariate descriptive statistics and chi-squared analyses for interactions. One hundred fifty-five medical students (82%) completed the survey. Most medical students reported the EM OCP to be unique compared to that of other disciplines (86%), integral to their clerkship eva...

Within the process, examination data, testing rationale, and test results are captured. AAST staging criteria are presented during data entry to describe and classify organ injuries accurately. A legible, time-stamped, conclusive report can be generated for printed or electronic entry into the medical record. The handheld version of the database runs on a Compaq iPAQ Pocket PC in either stand-alone mode or via LAN or WAN through the Internet. Microsoft Information Internet Server 5.0 provides data transaction services to Microsoft SQL Server 2000 to merge multiuser replicate data between the back ends stored on the desktop and handheld devices. The printed report provides superior documentation for comprehensive evaluation and management services, including history and physical examination, documentation of medical decision making, appropriateness of diagnostic/or therapeutic services, and coordination of care in accordance with Health Care Financing Administration (HCFA) regulations. Rapid data entry, ease of use, and appropriate documentation of detailed and legible patient visits and procedural notes are early benefits. Wireless data transmission between handheld devices and the desktop database provides the required speed, flexibility, and multitasking environment necessary for the mobile surgeon.

Cross-sectional, nationwide anonymous survey. Twenty-three Veterans Affairs spinal cord injury centers. One thousand five hundred fifty-six HCWs. The primary outcome was staff vaccination status. Independent variables included staff demographic and employment characteristics, health status, attitudes and beliefs about the vaccine, and implications for its use. The staff vaccination rate was 51%. Leading motivators of vaccine receipt were self-protection (77%) and patient protection (49%). The most common reasons for nonreceipt were concerns about side effects (49%), preventive quality (20%), and inconvenience (14%). Logistic regression results suggested that age of 50 years or older (OR, 1.47; P = .021), male gender (OR, 2.50; P < .001), strong belief in vaccine effectiveness (OR, 19.03; P = .008), and importance of HCW vaccination (OR, 20.50; P = .005) significantly increased the probability of vaccination. Recommending the vaccine to coworkers, patients, or patients' families was also associated with HCW vaccination (OR, 3.20; P < .001). Providers who did not believe the vaccine was protective (P < .001) or effective (P < .001) were less likely to recommend it to patients. Strategies to increase vaccination rates among HCWs should address concerns about side effects, effectiveness, and protective value of the vaccine and access to it. The impact of provider recommendations should be stressed. Vaccination and subsequent prevention of illness may limit morbidity and mortality, thus benefiting HCWs, healthcare facilities, and patients.

In this study, lactating Wistar rats on the 12th day of lactation were divided in the following groups: sham-operated (SO) and adrenalectomized (ADX) receiving no treatment; SO and ADX starved for 24 h and refed intragastrically with 2.5 ml of 50% glucose solution, 2 h before the experiment (SOR and ADXR) and ADX receiving substitute therapy with dexamethasone (ADX + DEX). Sacrifices were performed 2 days after surgery. Weight, lipid content and in vivo lipogenesis rate were evaluated in mammary gland (M.GLAND), liver, parametrial white adipose tissue (PARA) and interescapular brown adipose tissue (BAT). ATP citrate lyase activity was measured in M.GLAND, liver and PARA of SO, ADX and ADX + DEX. The rate of lipogenesis and 14CO2 production from 14C-glucose by isolated acini from M.GLAND and plasma glucose were also determined. In ADX rats, food intake, lipid content, in vivo lipogenesis rate and ATP citrate lyase activity in M.GLAND were significantly lower than those in SO rats. The M.GLAND lipogenesis rate of SOR group was similar to the value found in SO rats. In ADXR rats, the M.GLAND lipogenesis rate was not normalized. However, the therapy with DEX elevated lipid content, in vivo lipogenesis rate and ATP citrate lyase activity to levels similar to those in SO. These results suggest that the glucocorticoids are essential for the occurrence of normal lipid synthesis in M.GLAND during lactation.
