A systematic review and meta-analysis of delayed coronary artery access for coronary angiography with or without percutaneous coronary intervention (PCI) in patients who underwent transcatheter aortic valve replacement (TAVR).

Coronary artery disease (CAD) and severe aortic valve stenosis frequently coexist. Given the progressive nature of CAD, silent or non-significant CAD may become symptomatic or functionally relevant years after TAVR. However, there is a paucity of data documenting the feasibility of either coronary angiography and/or PCI after TAVR.

Left Atrial High-grade Sarcoma With Focal Osteosarcomatous Differentiation.

Approximately 75% of cardiac tumors are benign, and 25% are malignant cardiac tumors. Of these, sarcomas are extremely rare and have been described in isolated case reports. Due to its rarity, there is no published guideline for the management of this pathological entity.

Qualitative Evaluation of the Implementation of an Integrated Care Delivery Model for Chronic Patients with Multi-Morbidity in the Basque Country.

Introduction: The objective of this study was to assess a model for improving healthcare integration for patients with multiple chronic diseases in an integrated healthcare organisation in the Basque Country and to propose areas for improvement.

Methods: We organised four nominal groups composed of representatives from different categories of clinicians involved in the development of an integrated healthcare organisation and in the integrated care of patients with multiple diseases, namely, internists, general practitioners, and primary care and hospital nurses.

Results: The aspect rated most positively was the concept itself of an integrated care model, which is able to improve communication between levels of care, increase the quality of the care provided and enhance patient safety.

Wikipedia vs peer-reviewed medical literature for information about the 10 most costly medical conditions.

Context: Since its launch in 2001, Wikipedia has become the most popular general reference site on the Internet and a popular source of health care information. To evaluate the accuracy of this resource, the authors compared Wikipedia articles on the most costly medical conditions with standard, evidence-based, peer-reviewed sources.

Methods: The top 10 most costly conditions in terms of public and private expenditure in the United States were identified, and a Wikipedia article corresponding to each topic was chosen.

Use of Cuban recombinant human erythropoietin in Parkinson's disease treatment.

Introduction: Recombinant human erythropoietin is used primarily to treat anemia. There is evidence of its neuroprotective capacity from preclinical studies in Parkinson's disease and other neurodegenerative diseases. Recombinant human erythropoietin produced in Cuba (ior-EPOCIM) is registered and approved for use in humans in Cuba and in a number of other countries.

Cognitive changes after stem cell transplantation in a patient with subcortical stroke.

The authors report a case of a 55-year-old Caucasian woman who received autologous bone marrow stem cell transplantation 3 years after a subcortical stroke. She exhibited positive cognitive changes 6 months and 1 year after the surgery without rehabilitation. The blood flow changes, measured with SPECT, were statistical significant in prefrontal areas.

Stratified active screening: where neurotechnology meets public health.

Nearly one quarter of the global burden of disease stems from neurological, psychiatric and neurodevelopmental disorders due to malformations or dysfunctions of the central nervous system.[1] Such neuropsychiatric conditions influence quality of life worldwide, causing one third of years lost due to disability (YDL).[2] Ranging from congenital conditions to dementias of the elderly, these disorders appear throughout the life cycle and also account for a substantial proportion of mortality.

A theoretical formulation of the electrophysiological inverse problem on the sphere.

The construction of three-dimensional images of the primary current density (PCD) produced by neuronal activity is a problem of great current interest in the neuroimaging community, though being initially formulated in the 1970s. There exist even now enthusiastic debates about the authenticity of most of the inverse solutions proposed in the literature, in which low resolution electrical tomography (LORETA) is a focus of attention. However, in our opinion, the capabilities and limitations of the electro and magneto encephalographic techniques to determine PCD configurations have not been extensively explored from a theoretical framework, even for simple volume conductor models of the head.

Assessing acute middle cerebral artery ischemic stroke by quantitative electric tomography.

This paper focuses on the application of quantitative electric tomography (qEEGT) to map changes in EEG generators for detection of early signs of ischemia in patients with acute middle cerebral artery stroke. Thirty-two patients were studied with the diagnosis of acute ischemic stroke of the left middle cerebral artery territory, within the first 24 hours of their clinical evolution. Variable Resolution Electrical Tomography was used for estimating EEG source generators.

[Fecal incontinence in the elderly].

Unlabelled: Fecal incontinence (FI) is a devastating condition that affects quality of life. Age and gender are related with the prevalence of FI. In adults, prevalence varies from 2% to 7%.

Exploratory EEG data analysis for psychophysiological experiments.

A method for the exploratory analysis of electroencephalographic (EEG) data for neurophysiological experiments is presented. It is based on a time-frequency decomposition of the EEG time series, which is measured by several electrodes in the scalp surface, and includes the computation of a statistic that measures the deviations of the log-power with respect to the pre-stimulus average; the computation of a significance index for these deviations; a new type of display (the time-frequency-topography plot) for the visualization of these indices, and the segmentation of the time-frequency plane into regions with uniform activation patterns. As a particular example, an experiment to study EEG changes during figure and word categorization is analyzed in detail.

Sources of abnormal EEG activity in spontaneous intracerebral hemorrhage.

Unlabelled: This report describes the results obtained with EEG source analysis in the frequency domain (FD-VARETA), in 14 patients with brain hemorrhages; 6 hemorrhages were located in the putaminal region, 1 was mesencephalic and 7 were lobar cerebral hemorrhages. Our goal was to evaluate FD-VARETA accuracy for the localization of fast growth expansive brain lesions. FD-VARETA produces brain electromagnetic tomography images of EEG sources in every frequency.
