This paper for the first time discusses a computational study of using magneto-electric (ME) nanoparticles to artificially stimulate the neural activity deep in the brain. The new technology provides a unique way to couple electric signals in the neural network to the magnetic dipoles in the nanoparticles with the purpose to enable a non-invasive approach. Simulations of the effect of ME nanoparticles for non-invasively stimulating the brain of a patient with Parkinson’s Disease to bring the pulsed sequences of the electric field to the levels comparable to those of healthy people show that the optimized values for the concentration of …

Rodent Traumatic Brain Injury As A Model For Human Traumatic Axonal Damage And Neurodegeneration, Nils Henninger
Nils Henninger
Traumatic brain injury (TBI) is inherently heterogeneous with a complex underlying pathophysiology. Over the past decades many attempts have been undertaken to develop novel and innovative ways to mimic human aspects of TBI in rodents. This presentation will provide a brief overview of translationally relevant rodent TBI models with special emphasis on mild-to-moderate injuries and associated pathology.

The Role Of Multiple Sclerosis As A Risk Factor For The Development Of Osteoporosis, Christopher Perrone, Christine M. Foley, Linda C. Churchill, Sybil L. Crawford, Judith K. Ockene, Carolina Ionete
Sybil L. Crawford
Background: Osteoporosis is the most common bone disease in the United States, and it is particularly common among women with multiple sclerosis (MS). However, despite this association, the temporal relationship between these two conditions has not been previously studied. Data from the Women’s Health Initiative provides a unique opportunity to examine the risk of developing osteoporosis over time in individuals diagnosed with MS. Objective: The purpose of this study is to refine the relationship between MS and osteoporosis, clarifying the impact of environmental and pharmacologic factors on each condition, as well as addressing treatment and preventative efforts for a patient …

Dr Robert Brown
Cerebral edema is the one of the most significant predictors of poor outcome after traumatic brain injury. It is still unclear what the pathophysiological and cellular mechanisms and predictors of post-traumatic edema are. The exponential growth in genetic information has opened an avenue for investigation in traumatic brain injury and implicated specific genes in the pathophysiology of post-traumatic injury edema. Two examples are the Aquaporin-4 and CACNA1 genes, which respectively encode water and calcium channels. The Aquaporin-4 gene on chromosome 18q11.2-12.1 encodes the Aquaporin-4 protein (AQP4) water channel. AQP4 is one of the bidirectional high capacity water channels that is …

Brazilian Longitudinal Study Of Adult Health (Elsa-Brasil): Objectives And Design., Paulo A. Lotufo
Paulo A Lotufo
The Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) aims to contribute relevant information with respect to the development and progression of clinical and subclinical chronic diseases, particularly cardiovascular diseases and diabetes. In this report, the authors delineate the study's objectives, principal methodological features, and timeline. At baseline, ELSA-Brasil enrolled 15,105 civil servants from 5 universities and 1 research institute. The baseline examination (2008-2010) included detailed interviews, clinical and anthropometric examinations, an oral glucose tolerance test, overnight urine collection, a 12-lead resting electrocardiogram, measurement of carotid intima-media thickness, echocardiography, measurement of pulse wave velocity, hepatic ultrasonography, retinal fundus photography, and an …

This paper reassessed in Brazil, the concept of "Medical ecology" i introduced in 1961 to describe the relationship and utilization of health care services by a given population. This was a cross-sectional telephone survey among a random sample of people enrolled in a private HMO. We interviewed a random sample of non-pregnant adults over age 18 using 10 questions about symptoms and health care use during the month prior to interview. The final sample consisted of 1,065 participants (mean age 68 years, 68% female). From this sample, 424 (39.8%) reported the presence of symptoms, 311 (29.2%) had a medical office …

Paulo A Lotufo
Chronic Non-Communicable Diseases are the main source of disease burden in Brazil. In 2011, the Brazilian Ministry of Health launched the Strategic Plan of Action for Management of Chronic Non-Communicable Diseases focusing on population-based interventions to manage cardiovascular diseases, diabetes, cancer, and chronic respiratory diseases mainly through fi ghting tobacco use, unhealthy diets, physical inactivity and the harmful use of alcohol. Although a signifi cant number of scientifi c studies on chronic diseases and their risk factors have been undertaken in Brazil, few are of cohort design. In this context, the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil), a cohort …

A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo
A Reappraisal Of Stroke Mortality Trends In Brazil (1979 To 2009), Paulo A. Lotufo
Paulo A Lotufo
Background: Brazil has the highest cerebrovascular death rate in the Western Hemisphere. We investigated temporal trends according to gender and stroke subtypes. Methods: We analysed mortality rates between 1979 and 2009 for different stroke subtypes. Data were stratified by sex and age (35–74 y). The annual percent change (APC) and significant changes in the trends were identified with joinpoint Poisson regression. The average annual percent change (AAPC) for 2005-09 was presented because that period had the best quality of information. Results: After excluding deaths due to stroke sequels, for men, the APCs (95% confidence intervals) were: 1979-84: 0.7 (-0.8 to …

Iscore: A Risk Score To Predict Stroke Mortality, Gustavo Saposnik
Gustavo Saposnik
Stroke is a leading cause of death and adult disability. The ability to estimate prognosis in acute stroke patients directly affects treatment decisions for patients. It may also guide supportive care plans, facilitate patient and/or family counseling or discussions pertaining to end-of-life decisions. At the population level, prognostic estimations may assist policymakers in conducting fair comparisons when evaluating stroke fatality among different facilities for hospital outcomes and performance assessment. Clinicians usually rely on their own personal experience or average mortality reported in observational studies, which do not account for valuable information available at the time of the hospital presentation. Unfortunately, …

Prevalence Of Thyroid Disorders Among Older People: Results From The São Paulo Ageing & Health Study, Paulo A. Lotufo
Paulo A Lotufo
This study aimed to estimate prevalence of thyroid disorders in the São Paulo Ageing & Health Study, an epidemiological study addressing several health-adverse outcomes among elderly people living in a poor area of São Paulo, Brazil. All participants answered a questionnaire and had a blood sample collected to assess levels of tireotropic hormone and free-thyroxine. Among 1,373 people (60.8% women), prevalence rates (95% confidence interval) for thyroid dysfunction (%) were: overt hyperthyroidism, 0.7% (0.2-1.1) [women: 0.8% (0.2-1.5); men: 0.4% (0.01-0.9)]; overt hypothyroidism, 5.7% (4.5-6.9) [women: 5.9% (4.3-7.5); men: 5.4% (3.5-7.3)]; subclinical hyperthyroidism, 2.4% (1.6-3.2) [women: 2.8% (1.6-3.9); men: 1.9% (0.7-3.0)]; …
Organized Outpatient Stroke Care, Gustavo Saposnik
Organized Outpatient Stroke Care, Gustavo Saposnik
Gustavo Saposnik
Background and Purpose—Organized inpatient stroke care decreases mortality and morbidity irrespective of patient age, stroke severity, or stroke subtype. Limited information is available on whether organized outpatient care models such as stroke prevention clinics (SPC) improve outcomes after a transient ischemic attack or ischemic stroke. We compared 1-year mortality and stroke readmission in patients with transient ischemic attack or ischemic stroke referred versus not referred to an SPC. Methods—This was a retrospective cohort study including 16 468 consecutive patients with ischemic stroke or transient ischemic attack who were seen in the emergency department or admitted to a hospital between July …
