Brain structure in movement disorders: a neuroimaging perspective.

Purpose of review: An overview of recent advances in structural neuroimaging and their impact on movement disorders research is presented. Recent findings: Novel developments in computational neuroanatomy and improvements in magnetic resonance image quality have brought further insight into the pathophysiology of movement disorders. Sophisticated automated techniques allow for sensitive and reliable in-vivo differentiation of phenotype/genotype related traits and their interaction even at presymptomatic stages of disease. Summary: Voxel-based morphometry consistently demonstrates well defined patterns of brain structure changes in movement disorders. Advanced stages of idiopathic Parkinson's disease are characterized by grey matter volume decreases in basal ganglia. Depending on the presence of cognitive impairment, volume changes are reported in widespread cortical and limbic areas. Atypical Parkinsonian syndromes still pose a challenge for accurate morphometry-based classification, especially in early stages of disease progression. Essential tremor has been mainly associated with thalamic and cerebellar changes. Studies on preclinical Huntington's disease show progressive loss of tissue in the caudate and cortical thinning related to distinct motor and cognitive phenotypes. Basal ganglia volume in primary dystonia reveals an interaction between genotype and phenotype such that brain structure changes are modulated by the presence of symptoms under the influence of genetic factors. Tics in Tourette's syndrome correlate with brain structure changes in limbic, motor and associative fronto-striato-parietal circuits. Computational neuroanatomy provides useful tools for in-vivo assessment of brain structure in movement disorders, allowing for accurate classification in early clinical stages as well as for monitoring therapy effects and/or disease progression.

Ongoing Covenant with Black Iowa, 2006

This Manual is designed to help targeted communities organize and train local steering groups and task force leaders. The Ongoing Covenant with Black Iowa (OCBI) model will engage and empower African Americans in various communities to work together in developing strategies that bridge local priorities to statewide goals. Trained Task Force Leaders play a critical role in establishing productive dialogue and planning that is essential to moving the OCBI forward in meeting its goals. They must ensure consistency within each Task Force as the OCBI is a multilevel partnership and collaboration among local communities, the Commission on the Status of African Americans and the Covenant with Black America. Task Force Leaders assist with constructive dialogue among local residents to engage and focus on the issues, and work collectively towards a solution. Patience in developing a strategy and trained Task Force Leaders are essential to the success of the OCBI. It is our hope that this Manual will serve as a guide to assist you in all aspects of building your local strategic plan.

Iowa Commission on the Status of African Americans Annual Report, Fiscal Year 2006

A Public Intellectual recently suggested that I read the book Life Out Of Context by the very productive writer Walter Mosley. In this book, Mosley began to summarize a speech that was given by Harry Belafonte. Belafonte made a comparison between a particular Olympic relay race and the Civil Rights Movement. In the race, an experienced runner stumbled a little while passing the baton, and the race was lost. For Belafonte, this momentary slip was a metaphor for the failure of the Civil Rights Movement to “pass the baton” to the younger generation as “it moved past its original phase and into the latter part of the century.” Regardless of your views of the strengths and weaknesses of the Civil Rights Movement, I think all of us would agree that the current issues facing Black Iowa today--e.g., the need for economic development, increased educational achievement and more political involvement in our communities--demand our immediate attention and action. This urgency requires that we cross generational, class, and territorial boundaries within the state to collaborate among ourselves and with others to deal constructively with these issues. We cannot afford to have another “momentary slip.” Serving as the Administrator for ICSAA allows me to serve Black Iowa in a significant way, and Kimberly Cheeks and I in this Division look forward to the work ahead over the next several months and years. Working closely with Walter Reed, Director of the Department of Human Rights, along with so many others across this state, we are keenly aware that we are provided with a great opportunity to positively impact the quality of life for African-Americans in Iowa.

Change of individual BMI in Switzerland and the USA: a multilevel model for growth

Objective The aim is to analyze and compare individual BMI growth patterns of adults from Switzerland and the U.S. Methods The analyses are based on data from two population representative longitudinal household surveys, one from Switzerland, the other from the U.S. Each data set contains up to four data points for each adult individual. We use multilevel models for growth. Results It can be shown that growth patterns are different in different cohorts in the two countries: there are only small growth differences in the youngest and oldest, but large differences in the middle ages. The individual BMI increase of the middle age Swiss amounts to only half of that in the comparable U.S. individuals. Conclusion Given the much higher BMI level especially in the youngest cohort, this points to severe obesity problems in the U.S. middle aged population in the near future. A positive correlation between individual BMI level and growth may aggravate this fact.

Free-breathing black-blood coronary MR angiography: initial results

The authors developed a free-breathing black-blood coronary magnetic resonance (MR) angiographic technique with a potential for exclusive visualization of the coronary blood pool. Results with the MR angiographic technique were evaluated in eight healthy subjects and four patients with coronary disease identified at conventional angiography. This MR angiographic technique accurately depicted luminal disease in the patients and permitted visualization of extensive continuous segments of the native coronary tree in both the healthy subjects and the patients. Black-blood coronary MR angiography provides an alternative source of contrast enhancement.

Hipertextualidad, multimedialidad, interactividad y publicidad en la prensa digital internacional. El caso de ‘Le Monde’, ‘USA Today’, ‘Clarín’ Y ‘The Telegraph'

Aquest treball té com a objecte l’anàlisi de la implantació de la hipertextualitat, la multimedialitat, la interactivitat i la publicitat com a elements vertebradors de la premsa digital internacional. Primerament, es descriuen de forma teòrica els meritats elements. A continuació, es presenten els resultats de l’estudi empíric desenvolupat, analitzant els anteriors factors, sobre quatre capçaleres digitals internacionals. Finalment, concloem que la implantació de les variables estudiades es troba en fase d'expansió, tot i que encara lluny del nivell òptim d'explotació; també que els diaris europeus són més proclius a fomentar l'ús de la hipertextualitat, mentre els americans prefereixen la multimedialitat; que els principals problemes a superar seran les formes tradicionals de pensar i treballar així com la falta d'inversió generalitzada i, per acabar, que el futur passarà per continuar en la línia de treball sense oblidar-se d'evolucionar.

Aortic vessel wall magnetic resonance imaging at 3.0 Tesla: a reproducibility study of respiratory navigator gated free-breathing 3D black blood magnetic resonance imaging.

The purpose of this study was to evaluate a free-breathing three-dimensional (3D) dual inversion-recovery (DIR) segmented k-space gradient-echo (turbo field echo [TFE]) imaging sequence at 3T for the quantification of aortic vessel wall dimensions. The effect of respiratory motion suppression on image quality was tested. Furthermore, the reproducibility of the aortic vessel wall measurements was investigated. Seven healthy subjects underwent 3D DIR TFE imaging of the aortic vessel wall with and without respiratory navigator. Subsequently, this sequence with respiratory navigator was performed twice in 10 healthy subjects to test its reproducibility. The signal-to-noise (SNR), contrast-to-noise ratio (CNR), vessel wall sharpness, and vessel wall volume (VWV) were assessed. Data were compared using the paired t-test, and the reproducibility of VWV measurements was evaluated using intraclass correlation coefficients (ICCs). SNR, CNR, and vessel wall sharpness were superior in scans performed with respiratory navigator compared to scans performed without. The ICCs concerning intraobserver, interobserver, and interscan reproducibility were excellent (0.99, 0.94, and 0.95, respectively). In conclusion, respiratory motion suppression substantially improves image quality of 3D DIR TFE imaging of the aortic vessel wall at 3T. Furthermore, this optimized technique with respiratory motion suppression enables assessment of aortic vessel wall dimensions with high reproducibility.
