Analysis of global stock index data during crisis period via complex network approach.

Considerable research has been done on the complex stock market, however, there is very little systematic work on the impact of crisis on global stock markets. For filling in these gaps, we propose a complex network method, which analyzes the effects of the 2008 global financial crisis on global main stock index from 2005 to 2010. Firstly, we construct three weighted networks. The physics-derived technique of minimum spanning tree is utilized to investigate the networks of three stages. Regional clustering ...

Headaches Due to Low and High Intracranial Pressure.

Headache disorders attributed to low and high intracranial pressure are commonly encountered in specialty headache practices and may occur more frequently than realized. While the headaches resulting from intracranial pressure disorders have what are conventionally thought of as defining characteristics, a substantial minority of patients do not manifest the "typical" features. Moreover, patients with intracranial pressure disorders may also have a preexisting primary headache disorder. Heightening the comp...

Home blood pressure monitoring in pediatric hypertension: the US perspective and a plan for action.

The 2017 US guidelines for pediatric hypertension place considerable emphasis on blood pressure measurements, which are the cornerstone for hypertension diagnosis and management. It is recognized that when the diagnosis of hypertension is based solely on office blood pressure measurements, many children are misclassified (over- or underdiagnosed). Therefore, out-of-office blood pressure evaluations using ambulatory or home blood pressure monitoring are often necessary to obtain an accurate diagnosis. Strong...

Effect of intracranial pressure control on improvement of cerebral perfusion after acute subarachnoid hemorrhage: A comparative angiography study based on temporal changes of intracranial pressure and systemic pressure.

Elevated intracranial pressure (ICP) is a well-known complication after aneurysmal subarachnoid hemorrhage (aSAH). This study focused on the different temporal changes in ICP, mean arterial pressure (MAP), and cerebral perfusion pressure (CPP) at the early stage of aSAH, throughout aneurysm embolization, and their effects on improvement in angiographic perfusion patterns.

Intracranial Pressure Trajectories: A Novel Approach to Informing Severe Traumatic Brain Injury Phenotypes.

Intracranial pressure in traumatic brain injury is dynamic and influenced by factors like injury patterns, treatments, and genetics. Existing studies use time invariant summary intracranial pressure measures thus potentially losing critical information about temporal trends. We identified longitudinal intracranial pressure trajectories in severe traumatic brain injury and evaluated whether they predicted outcome. We further interrogated the model to explore whether ABCC8 polymorphisms (a known cerebraledema...

The intraocular pressure could not be used to determine the intracranial pressure in patients with hydrocephalus.

An accurate intracranial pressure (ICP) measurement is vital for patients with hydrocephalus. ICP is generally measured by lumbar puncture opening pressure, which is invasive and has potential adverse side effects. Intraocular pressure (IOP) was investigated to measure ICP indirectly; however, its accuracy was controversial. We conducted this retrospective study to investigate whether IOP can be used as a surrogate for ICP in hydrocephalus patients.

Effects of Increased Intracranial Pressure Gradient on Cerebral Venous Infarction in Rabbits.

Cerebral venous infarction (CVI) is a rare vascular disease, most commonly caused by cerebral venous thrombosis, which leads to brain tissue ischemia and anoxia, followed by necrosis, hemorrhage, and infarct formation. CVI has diverse clinical manifestations; thus, diagnosis is very difficult, and the prognosis is poor. The goal of this study is to provide a theoretical basis for treating patients suffering from CVI combined with high intracranial pressure. To this end, a rabbit model of CVI was established...

Cranial morcellation decompression for refractory idiopathic intracranial hypertension in children.

Primary idiopathic intracranial hypertension (PIIH) in children is rare and has a poorly understood pathophysiology. It is characterized by raised intracranial pressure (ICP) in the absence of an identified brain lesion. Diagnosis is usually confirmed by the measurement of a high cerebrospinal fluid (CSF) opening pressure and exclusion of secondary causes of intracranial hypertension. Refractory PIIH may lead to severe visual impairment. The purpose of this study was to evaluate a cranial morcellation decom...
