From those who had never been vaccinated, 26.7% of patients did not consider influenza vaccine safe and effective vs. 13.5% among patients who had been vaccinated (P = .032). Only 7.6% considered that RD patients could not be vaccinated; 11.7% thought that influenza vaccine would worsen their RD symptoms. This study showed that concerns about safety, efficacy, side effects, fear of the vaccine, and knowledge of cost diminished vaccine uptake. These are factors related to confidence, complacency, and convenience as components of vaccine hesitancy that affect influenza vaccination in RD patients.

Morbidity and mortality outcomes for patients admitted for acute decompensated heart failure are poor and have not significantly changed in decades. Current therapies are focused on symptom relief by addressing signs and symptoms of congestion. The objective of this study was to test a novel neuromodulation therapy of stimulation of epicardial cardiac nerves passing along the posterior surface of the right pulmonary artery.

Fifteen subjects admitted for defibrillator implantation and ejection fraction ≤35% on standard heart failure medications were enrolled. Through femoral arterial access, high fidelity pressure catheters were placed in the left ventricle and aortic root. After electro anatomic rendering of the pulmonary artery and branches, either a circular or basket electrophysiology catheter was placed in the right pulmonary artery to allow electrical intravascular stimulation at 20 Hz, 4 ms pulse width, and ≤20 mA. Changes in maximum positive dP/dt (dP/dt

) indicated changes in ventricular contractmay benefit patients admitted for acute decompensated heart failure.OBJECTIVE. The objective of our study was to compare morphologic and functional dual-energy CT (DECT) parameters in patients with chronic thromboembolic disease (CTED) and chronic thromboembolic pulmonary hypertension (CTEPH). MATERIALS AND METHODS. Using the local CTEPH registry, we identified 28 patients with CTED and 72 patients with CTEPH. On each DECT examination, a clot burden score was calculated by assigning the following scores for chronic changes by location pulmonary trunk, 5; each main pulmonary artery (MPA), 4; each lobar branch, 3; each segmental branch, 2; and each subsegmental branch, 1. The total clot burden score was calculated by adding the individual scores from both lungs. Functional parameters were assessed using perfused blood volume (PBV) maps and included lung enhancement (in Hounsfield units), percentage of PBV, MPA peak enhancement (in Hounsfield units), maximum enhancement corresponding to 100, and the ratio of MPA peak enhancement to lung enhancement. A perfusion defect (PD) scoreat CTED is an intermediate clinical phenotype in the population with chronic pulmonary embolism.OBJECTIVE. The purpose of this study was to use quantitative dynamic contrast-enhanced MRI (DCE-MRI) to evaluate mesorectal microcirculation in patients with rectal cancer. MATERIALS AND METHODS. A total of 53 patients with semicircular rectal tumors underwent DCE-MRI with a 3-T MRI system before surgery. Enzalutamide price ROIs were manually delineated in the mesorectum that surrounded the tumor and the mesorectum that surrounded the normal rectal wall. DCE-MRI parameters including forward volume transfer constant (Ktrans), reverse volume transfer constant (kep), and fractional extravascular extracellular space volume (Ve) were estimated using computer software. Histopathologic analysis served as the standard reference. RESULTS. Mesorectum that surrounded the tumor showed significantly higher Ktrans val ues than mesorectum that surrounded normal rectal wall (mean, 0.069 ± 0.035 [SD] vs 0.039 ± 0.020 min-1; p less then 0.001). The tumor-surrounding mesorectum also showed higher Ve values than normal mesorectum (p less then 0.001). An opposite trend was observed for kep, but this was not significant (p = 0.077). A lower Ktrans of the tumor-surrounding mesorectum was observed in patients with malignant lymph nodes compared with those with benign lymph nodes (mean, 0.054 ± 0.027 vs 0.076 ± 0.036 min-1; p = 0.034). Although kep values for the tumor-surrounding mesorectum were higher in patients with tumors categorized as pathologic Tis (pTis) to pT2 than in those with pT3 tumors, the p value was close to 0.05 (p = 0.047). The tumor-surrounding mesorectum showed no significant differences in the aforementioned parameters between patients with positive MRI-detected extramural vascular invasion (mrEMVI) and those with negative mrEMVI. CONCLUSION. Mesorectum that surrounded rectal tumor had a higher blood flow than that close to the normal rectal wall. The blood flow decreased in the tumor-surrounding mesorectum when there was nodal involvement.OBJECTIVE. The purpose of this study was to analyze the contribution of dual-energy CT (DECT) to radiologist interpretation in the emergency department (ED) to determine whether recommendations for follow-up imaging decrease. MATERIALS AND METHODS. Reports of all DECT studies performed in an ED in 2016 were reviewed. A board-certified radiologist noted the number of times a report indicated that use of DECT techniques contributed to radiologist interpretation. For studies containing DECT findings in the report, the mixed datasets, representing conventional CT images, were read again separately. The difference between the numbers of follow-up studies recommended after conventional CT and DECT was converted into U.S. dollars by use of the Medicare fee schedule to estimate a projected cost benefit due to any reduction in follow-up imaging. RESULTS. The study included 3159 cases. DECT findings potentially altered management in 298 (9.4%) cases, increased diagnostic confidence in 455 (14.4%) cases, provided relevant information in 174 (5.6%) cases, helped characterize an incidental finding in 44 (1.4%) cases, and were mentioned to be noncontributory in three (0.09%) cases. DECT was not mentioned in the report in 2272 cases (71.9%). DECT findings avoided 162-191 recommended follow-up MRI examinations, 21-28 CT examinations, and 2-25 US examinations compared with conventional CT alone. The DECT findings also prompted one additional recommended interventional angiography procedure, one ventilation-perfusion scan, and one imaging-guided biopsy. The projected net cost reduction was $52,991.53-61,598.44. CONCLUSION. DECT added value to routine ED imaging by increasing diagnostic confidence, leading to a reduction in the number of recommended follow-up studies and a projected cost benefit.
