BACKGROUND AND PURPOSE Transient ischemic attack (TIA) patients are at risk of recurrent vascular events. The primary objectives were to evaluate among TIA patients the prevalence of sleep apnea and among patients with sleep apnea auto-titrating continuous positive airway pressure (auto-CPAP) adherence. The secondary objective was to describe among TIA patients with sleep apnea the recurrent va...
BACKGROUND AND PURPOSE Long-term population trends in the early risk of stroke after transient ischemic attack (TIA) are unknown. We hypothesized that there has been an appreciable decline in the risk of stroke after TIA for the last decade. METHODS Population-level cohort study from Victoria, Australia (population 5.6 million), using linked data from hospitals, emergency departments, and dea...
Background and Purpose—The ABCD score predicts the early risk of stroke after transient ischemic attack (TIA). However, data on the severity of recurrent events would also be useful. Do patients with high scores also have more severe early recurrent strokes, perhaps further justifying hospital admission? Do patients with low scores have a low early risk of recurrent TIA as well as recurrent str...
BACKGROUND Improving the recognition of transient ischaemic attack (TIA) at initial healthcare contact is essential as urgent specialist assessment and treatment reduces stroke risk. Accurate TIA detection could be achieved with clinical prediction rules but none have been validated in primary care. An alternative approach using qualitative analysis of patients' experiences of TIA may identify ...
One hundred seventeen patients, 31 with TIA and 86 with cerebral infarction, had angiographically verified atherosclerosis within the relevant carotid artery territory and normal CSF. They were treated with anticoagulants for a mean of 11.1 months. No TIA but 1 cerebral infarction, appearing during inadequate anticoagulant therapy, was registered. Seventy-six of the patients, 20 with TIA and 56...
Programmable Logic Controllers (PLCs) are the point of interaction between cyber and physical world, thus have been target previous cyber-attacks that caused disruption. To understand effectiveness state-of-the-art security mechanisms built into these devices, this paper presents an in-depth analysis performed on Siemens PLC environment, particularly communication protocol known as S7CommPlus. ...
With considerable advances in technology, ultrasound, as a noninvasive procedure has been more frequently used for diagnosis of liver diseases and portal hypertension (P.H.). Venography and splenoportography, both are invasive procedures with considerable X-ray exposure. The information obtained from these procedures are limited only to condition of vesseles, while with ultr...
Chronic cerebrovascular disease and large ischemic stroke are both associated with cognitive impairment. Much less is known about the acute cognitive sequelae of transient ischemic attack (TIA). Although often overlooked, there is increasing evidence that cognitive impairment does occur following TIA. In some patients, cognitive changes persist after resolution of focal neurological deficits, b...
Working Memory Impairment in Transient Ischaemic Attack: N-back as a Sensitive Measure for Detection
Abstract Background: Transient ischaemic attack (TIA) can lead to lasting changes in brain structure and function resulting cognitive impairment. Cognitive screening tools may lack sensitivity for detecting impairments, particularly executive function, which tends be the earliest affected domain vascular Aim: In this preliminary study, we examine a working memory (WMem) task as sensitive measur...
Tumour necrosis factor (TNF)-alpha mRNA contains an AU-rich element (ARE) in its 3' untranslated region (3'UTR), which determines its half-life and translational efficiency. In unstimulated macrophages, TNF-alpha mRNA is repressed translationally, and becomes efficiently translated upon cell activation. Gel retardation experiments and screening of a macrophage cDNA expression library with the T...
