Abstract:

Movement disorders are a group of syndromes that often arise due to neurological abnormalities. Approximately 40 million Americans are affected by some form of movement disorder, significantly impacting patients’ quality of life and their ability to live independently. Deep brain stimulation (DBS) is one treatment that has shown promising results in the past couple decades, however, the currently used open-loop system has several drawbacks. By implementing a closed-loop or adaptive DBS (aDBS) system, the need for expensive parameter reprogramming sessions would be reduced, side-effects may be

Abstract:

In the DBS surgical treatment the location of the electrodes has direct influence on the success rate of treatment. Considering the fact that MRI imaging is not compatible with metal, post-operative CT images should be used to locate the electrodes on pre-operative MRI images which contain information about soft tissues. It is impossible to locate them directly since the area around the electrodes on the CT image has been corrupted due to the blockage of x-ray by them. This work attempts to precisely estimate the position of the DBS electrodes inside the brain by means of images gathered fr

One of the main characteristics of Parkinson's disease (PD) is an exaggerated oscillatory activity in the beta band (12-30 Hz). This activity has been linked to the rise of symptoms such as bradykinesia and akinesia. Even if dopamine replacement therapy (oral intake of dopamine pro-drug levodopa) reverses these symptoms, the effect of the treatment on the beta band activity has still not been completely understood. Therefore, here the temporal dynamics of beta band activity in human patients affected by PD were characterized with and without levodopa treatment. Local-field-potential (LFP) reco

The spatial distribution of these clinical scores can be used to construct a functional model which closely models the expected efficacy of stimulation in the region.

A method for extraction of proteins from dried blood spots (DBS) for analysis using Proseek is developed and evaluated.

These advantages include for example minimal patient invasiveness, sampling simplicity and non regulated sample transportation. Highly reproducible quantitative detection of 92 proteins is demonstrated from a 1.2 mm in diameter DBS disk. The DBS inter spot analysis precision (7% coefficient of variance) is comparable to plasma inter assay precision (6% coefficient of variance).

Abstract:

Atualmente se tem bem estabelecido o tratamento para Doença de Parkinson, dentre eles o DBS (Deep Brain Stimulation). Embora haja controvérsias, muitos estudos têm demonstrado os efeitos adversos do DBS sobre a cognição, humor e comportamento. Assim, este estudo buscou investigar a associação entre os prejuízos cognitivos no pós-operatório e a volumetria cerebral em pacientes parkinsonianos submetidos a DBS, verificando se a correlação entre ambos pode ser considerada fator de risco para os prejuízos encontrados no pós-operatório. Fizeram parte da população estudada 25 indivíduos, 80% do sexo

Abstract:

L'une des principales barrières à la prise en charge optimale des patients sous traitement antirétroviral est l'accès limité aux tests de charge virale (CV) et de génotypage particulièrement en milieu décentralisé. Ces tests ne sont généralement disponibles qu'au niveau des structures sanitaires centrales de grandes villes et le plasma en est l'échantillon de référence. Or, son transfert des régions périphériques vers les laboratoires de références est difficile, voire impossible. Pour rapprocher les patients du laboratoire, nous avons démontré la possibilité d'assurer un suivi virologique com
