Flow Diverters for Intracranial Aneurysms

Abstract: Flow diverters (pipeline embolization device, Silk flow diverter, and Surpass flow diverter) have been developed to treat intracranial aneurysms. These endovascular devices are placed within the parent artery rather than the aneurysm sac. They take advantage of altering hemodynamics at the aneurysm/parent vessel interface, resulting in gradual thrombosis of the aneurysm occurring over time. Subsequent inflammatory response, healing, and endothelial growth shrink the aneurysm and reconstruct the parent artery lumen while preserving perforators and side branches in most cases. Flow diverters have already allowed treatment of previously untreatable wide neck and giant aneurysms. There are risks with flow diverters including in-stent thrombosis, perianeurysmal edema, distant and delayed hemorrhages, and perforator occlusions. Comparative efficacy and safety against other therapies are being studied in ongoing trials. Antiplatelet therapy is mandatory with flow diverters, which has highlighted the need for better evidence for monitoring and tailoring antiplatelet therapy. In this paper we review the devices, their uses, associated complications, evidence base, and ongoing studies. 1. Introduction During recent decades, endovascular treatment of cerebrovascular aneurysms has evolved to include unassisted coil embolization techniques, whose efficacy and safety are supported by class-1-evidence, assisted coil embolization techniques, and newly developed techniques using flow diverters [1]. While the various coil embolization techniques, including balloon assisted and stent assisted coiling, are targeted towards the aneurysm sac, flow diverters represent a paradigm shift with the intervention carried out in the parent artery [2, 3]. Flow diverter aneurysm embolization can be combined with coil embolization, further expanding the options available to clinicians and patients [3]. Flow diverters were first tested in untreatable aneurysms or those that had failed previous endovascular therapy [2]. With the approval of these devices in the USA, Europe, and other countries experience with “off-label” uses is evolving. In this paper we review the use of flow diverters for treatment of intracranial cerebral aneurysms. We review the putative mechanism of action, the technical features of devices and their uses, and the evidence for efficacy and safety of flow diverters for intracranial aneurysms. 2. Flow Diversion and Mechanism of Action Flow diverters are stent-like devices that are deployed endovascularly to treat aneurysms. Conceptually, flow diverters allow

Low Dietary Magnesium Intake and Hypertension  [PDF]
Lindsy Kass, Keith R. Sullivan
World Journal of Cardiovascular Diseases (WJCD) , 2016, DOI: 10.4236/wjcd.2016.612048
Purpose: Magnesium (Mg) is a key factor in blood pressure regulation. However, only in recent years, magnesium dietary intake has been studied in relation to hypertension, with equivocal conclusions. Further no comparisons have previously been made between the UK general population and primary hypertensives, the UK RNI and the USARDA. Methods: Twenty-five hypertensives (HT) (mean age 63.4 y) and twenty-one normotensives (mean age 46.7 y) were recruited from the same geographical area. Food diaries were completed and analysed to determine average daily Mg intake. Mg intake was compared between the observed group (OB), normotensives (NT) and general population (GP) and both the UK RNI and the USA RDA. Results: Study participants had a significantly lower dietary Mg intake than the UK RNI (p < 0.05) and the US RDA (p < 0.05). Intake for HT males was significantly lower (p < 0.0001) than the external control (general population) and, for HT females, intake was significantly lower than the NT (p = 0.006). The findings also suggest that with ageing there is a reduction in daily dietary Mg intake. Finally, when UK external controls were compared to the USA RDA for both males and females they were found to be around 35% and 30% respectively below the recommended values. Conclusions: Daily Mg intake in hypertensives is lower than the general population, the UK RNI and the USA RDA. Daily magnesium intake reduces with age. These findings suggest that low Mg dietary intake increases the risk of hypertension.

Comment: The Importance of Jeffreys's Legacy

Statistics , 2010, DOI: 10.1214/09-STS284A
Abstract: Theory of Probability is distinguished by several high-level philosophical attitudes, some stressed by Jeffreys, some implicit. By reviewing these we may recognize the importance in this work in the historical development of statistics. [arXiv:0804.3173]
Oil-Price Forecasting Based on Various Univariate Time-Series Models  [PDF]
Gurudeo Anand Tularam, Tareq Saeed
American Journal of Operations Research (AJOR) , 2016, DOI: 10.4236/ajor.2016.63023
Abstract: Time-series-based forecasting is essential to determine how past events affect future events. This paper compares the performance accuracy of different time-series models for oil prices. Three types of univariate models are discussed: the exponential smoothing (ES), Holt-Winters (HW) and autoregressive intergrade moving average (ARIMA) models. To determine the best model, six different strategies were applied as selection criteria to quantify these models’ prediction accuracies. This comparison should help policy makers and industry marketing strategists select the best forecasting method in oil market. The three models were compared by applying them to the time series of regular oil prices for West Texas Intermediate (WTI) crude. The comparison indicated that the HW model performed better than the ES model for a prediction with a confidence interval of 95%. However, the ARIMA (2, 1, 2) model yielded the best results, leading us to conclude that this sophisticated and robust model outperformed other simple yet flexible models in oil market.
Assessing the Factors Influencing Migration Decision of Climate Refugees in Coastal Areas of Bangladesh  [PDF]
Tareq Mahamud Abir, Xiaojun Xu
American Journal of Climate Change (AJCC) , 2019, DOI: 10.4236/ajcc.2019.82011
Abstract: The major impacts of climate change play a substantial role in triggering human migration, especially in the coastal areas. The individual or combined effects of climate change are likely to trigger mass human movement both within and across international borders. People rarely move for a single reason; the motivation to migrate is complex of many factors. The main goal of this article is to identify the factors related to the decision to migrate taken by refugees in the coastal area. To assess this objective we employ exploratory factor analysis and structural equation modeling (SEM) and find that different factors influence refugees’ migration decision differently. From the findings, it is seen that loss of shelter, extreme events, decreasing soil fertility and food shortage, variability in temperature patterns and exhaustion of natural resources are the most important environmental factors that affect the decision to migrate of climate refugees. Low income, increasing price, decreasing purchasing power are the most important economic factors that influence migration decision. No social factors have significant effect on migration decision while safety as a political factor has a moderate influence on refugees’ decision to migrate. Finally, this article provides some recommendations for recognition of and protection for migrants forced to move to safer places due to certain direct impacts of climate change, notwithstanding the existence of multi-causality.

Abstract: Marketing innovation and creativity requires organizations to continuously search for the development of its products and services in order to achieve new gains for its clients and fulfill their needs and requirements; a model is proposed to illustrate the role of marketing innovation and creativity in achieving competitive advantage for Jordanian banks. The results of the study shows that the independent variables (Marketing Innovation and Creativity) which were tested through the hypothesis and illustrated in the model plays a major role in achieving competitive advantage. The study shows the innovation and creativity are crucial in organizations success. The study concluded that through marketing innovation and creativity, Jordanian banks can improve their businesses and achieve competitive advantage.
