Right ventricular failure continues to be the Achilles heel in the management of heart failure patients. Traditionally, either high doses of inotropes and inhaled nitric oxide or jerry‐rigged temporary mechanical devices have been used to support failing right ventricles. No durable implantable right ventricular assist device has been developed to address this long‐standing concern. Because of this vacuum of innovation, surgeons have started using the third‐generation LVADs to support the right ventricle. The HeartMate 3 (Abbott) LVAD is a safe and effective therapy for the management of biventricular failure.  相似文献

Background

The purpose of this analysis is to describe the differences in cardiac magnetic resonance characteristics between benign and malignant tumors, which would be helpful for surgical planning.

Methods

This was a prospective cohort study of 130 patients who underwent cardiac magnetic resonance imaging for evaluation of a suspected cardiac mass. After excluding thrombi and tumors without definitive diagnosis, 66 tumors were evaluated for morphologic features and tissue composition.

Results

Of the 66 patients, 39 (59.0%) had malignant tumors and 27 (41.0%) had benign tumors. Patients with malignant tumors were younger when compared with those with benign tumors (age 51 years [42.8-60.0] vs 65 years [60.0-71.0] median). Malignant tumors more often demonstrated tumor invasion (69% vs 0% P < .001) and were more often associated with pericardial effusion (41% vs 7.4% P = .004). Presence of first-pass perfusion (100% vs 33% P < .001) and late gadolinium enhancement (100% vs 59.2%, P < .001) were significantly higher in malignant tumors. In logistic regression modeling, tumor invasion (P < .001) and first-pass perfusion (P < .001) were independently associated with malignancy. Furthermore, using classification and regression tree analysis, we developed a decision tree algorithm to help differentiate benign from malignant tumors (diagnostic accuracy ~90%). The algorithm-weighted cost of misclassifying a malignant tumor as benign was twice that of classifying a benign tumor as malignant.

Conclusions

Our study demonstrates that cardiac magnetic resonance imaging is a useful noninvasive method for differentiating malignant from benign cardiac tumors. Tumor size, invasion, and first-pass perfusion were useful imaging characteristics in differentiating benign from malignant tumors.  相似文献

Random samples of 358 Jews and 162 Arabs in Israel aged 50 to 75 were compared by telephone survey for colorectal cancer (CRC) screening performance and intentions. Participants completed questionnaires on CRC screening, health beliefs, health locus of control, and CRC worries; rate of CRC screening and intention to be screened proved lower among Arabs. They received fewer recommendations from physicians, perceived lower severity of CRC and lower benefits of early detection of CRC, and had lower cancer worries, lower internal health locus of control, and higher external health locus of control. Jewish/Arab ethnicity predicted ever undergoing screening and screening intention before cognitive perceptions and worries were entered. After that, perceiving higher susceptibility and more benefits to screening, and having lower external health locus of control predicted CRC screening and screening intention, which was associated with higher cancer worries. Programs should be tailored to address ethnic groups' different health beliefs.  相似文献

Vernix caseosa occasionally dissects underneath the amnion, presumably following rupture of the amnion prior to rupture of the chorion laeve. We describe the clinicopathological features of 18 cases in which large quantities of vernix caseosa were present beneath the amnion of the parietal membranes or the chorionic plate. The subamnionic vernix caseosa was an unexpected microscopic finding in each case and was not associated with any inflammation, giant cell reaction, or other chronic change in the adjacent membranes. The gestational age ranged from 29 to 42 weeks (mean, 37). Five (28%) of the 18 were twin pregnancies. Five (28%) were delivered by cesarean section. In no case was there a history of amniocentesis, prolonged rupture of membranes, or amnionic fluid leakage. None of the mothers had signs of amnionic fluid embolism. The absence of tissue response around the vernix caseosa suggests rupture of the amnion close to the time of delivery.  相似文献

BACKGROUND: Breast examinations (BE) for the early detection of breast cancer are the principal way of increasing survival rates in breast cancer. To date, BE practices among Jewish as compared with Arab women, and the factors associated with them have not been examined in Israel. OBJECTIVES: (1) To study differences in BE practices among Arab and Jewish women. (2) To characterize demographic, cognitive, and emotional factors related to Arab and Jewish women's BE practices. METHOD: In 2004, 489 Jewish women and 440 Arab women, ages 20-60, and randomly sampled from the female population of Israel, answered a telephone questionnaire related to BE practices, health beliefs, and breast cancer worries.  相似文献
