Editorial June 2013
As an editor of Journal of Research Nursing (JRN), I try to make every issue “balanced.” I ask myself, “Is there something for everyone who reads JRN?” I consider the clinical nurse, nurse researcher, nurse manager, and nurse in an educator role. I also think about others who may see and pick up JRN to read or who are doing research and see a citation for an article that appeared in JRN. Because articles cover topics involving patients during the whole life span (from prenatal to forensic imaging) and all imaging modalities and types of settings, the task of creating a balanced issue is not always easy. I also thin...

Risk Factors for Cerebral Embolization After Carotid Artery Stenting With Embolic Protection: A Diffusion-Weighted Magnetic Resonance Imaging Study in 837 Consecutive Patients Peripheral Artery Disease
Conclusions— Age, hypertension, lesion morphology, and aortic arch type were predictive for procedural-related cerebral embolic lesions during embolic protected CAS. Age, significant contralateral carotid stenosis, and complex aortic arch type were predictive for bilateral ischemic lesions. The clinical implications of ischemic lesions are not yet fully understood.

Isolated Third, Fourth, and Sixth Cranial Nerve Palsies from Presumed Microvascular versus Other Causes: A Prospective Study
Conclusions: In our series of patients with acute isolated ocular motor nerve palsies, a substantial proportion of patients had other causes, including neoplasm, GCA, and brain stem infarction. Brain MRI and laboratory workup have a role in the initial evaluation of older patients with isolated acute ocular motor nerve palsies regardless of whether vascular risk factors are present.Financial Disclosure(s): The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Changes in Right Ventricular Function Measured by Cardiac Magnetic Resonance Imaging in Patients Receiving Pulmonary Arterial Hypertension-Targeted Therapy: The EURO-MR Study Pulmonary Arterial Hypertension
Conclusions— On-treatment changes in cardiac MRI–derived variables from left and right sides of the heart reflected changes in functional class and survival in patients with PH. Direct measurement of RV function using cardiac MRI can fully assess potential benefits of treatment in PH.

Associations of Durations of Antiplatelet Use and Vascular Risk Factors with the Presence of Cerebral Microbleeds
In conclusion, we found a significant association between aspirin use and deep or infratentorial microbleeds, but this association may reflect the presence of hypertension as a confounding factor.

Hemorheology of Clinically Silent Multifocal Vascular Cerebral Lesions (P1.114)
CONCLUSIONS: We may suggest that a better red cell elasticity in patients results from a self-regulatory compensation. IgM molecules seem to play an opposite role to fibrinogen molecules in red cells aggregation phenomenon.Study Supported by: no supportedDisclosure: Dr. Kowal has nothing to disclose.

Early Menopause and the Risk of Silent Brain Infarction in Community-Dwelling Elderly Subjects: The Sefuri Brain MRI Study
Our previous study showed that the male predominance of silent brain infarction (SBI) was largely because of higher prevalence of alcohol habit and smoking in men than in women. In the present study, we further conducted an analysis of brain magnetic resonance imaging findings to examine whether early menopause contributes to SBI in community-dwelling subjects. Women were queried as to the age and cause of menopause, the total number of children, and the age at giving birth to her last child. Among 306 female subjects aged 60 years or older, univariate analysis showed that early menopause (total or natural) was significan...

Subjective Cognitive Failures in Patients With Hypertension Are Related to Cognitive Performance and Cerebral Microbleeds Brain and Cognition
Previous studies on the relationship between subjective cognitive failures (SCF) and objective cognitive function have shown inconsistent results. In addition, research on the association between SCF and imaging markers of cerebral small vessel disease is limited. We investigated whether SCF in patients with essential hypertension, who are at high risk of cerebral small vessel disease, are associated with objective cognitive function and magnetic resonance imaging manifestations of cerebral small vessel disease. We included 109 patients with hypertension who underwent extensive neuropsychological assessment, including ques...

Cerebral microbleeds in a multiethnic elderly community: Demographic and clinical correlates
Conclusions: Microbleeds in deep and lobar locations are associated with worse outcomes than microbleeds in either location alone, although the presence of lobar microbleeds appears to be more clinically relevant.Highlights:

Clinical Associations of Cerebral Microbleeds on Magnetic Resonance Neuroimaging
Susceptibility-weighted and gradient-recalled echo T2* magnetic resonance imaging have enabled the detection of very small foci of blood within the brain, which have been termed “cerebral microbleeds.” These petechial intraparenchymal hemorrhages have begun to emerge as diagnostically and prognostically useful markers in a variety of disease states. Severe hypertension and cerebral amyloid angiopathy are perhaps the best established microhemorrhagic conditions from neuroimaging literature; however, many others are also recognized including cerebral autosomal dominant arteriopathy, subcortical infarcts, and leukoencepha...

Automatic segmentation of white matter lesions on magnetic resonance images of the brain by using an outlier detection strategy
White matter lesions (WMLs) are commonly observed on the magnetic resonance (MR) images of normal elderly in association with vascular risk factors, such as hypertension or stroke. An accurate WML detection provides significant information for disease tracking, therapy evaluation, and normal aging research. In this article, we present an unsupervised WML segmentation method that uses Gaussian mixture model to describe the intensity distribution of the normal brain tissues and detects the WMLs as outliers to the normal brain tissue model based on extreme value theory.

Values of ambulatory blood pressure monitoring for prediction of cognitive function impairment in elderly hypertensive patients
Conclusion The study demonstrated that hypertensive patients diagnosed by ABPM have significantly more impaired cognitive function than control subjects as proved by the mini-mental state examination and brain MRI score of white matter disease.
