CONTEXT Worldwide, millions of patients with traumatic brain injury (TBI) suffer from persistent and disabling intelligence impairment. Post-traumatic amnesia (PTA) duration is a promising predictor of intelligence following TBI. OBJECTIVES To determine (1) the impact of TBI on intelligence throughout the lifespan and (2) the predictive value of PTA duration for intelligence impairment, using...
OBJECTIVES Superficial femoral artery (SFA) involvement in Takayasu arteritis (TAK) has rarely been reported. The purpose of this study was to investigate the clinical characteristic and clinical outcomes of endovascular therapy in such patients. METHODS We analysed the data collected from 105 consecutive patients with TAK, who were diagnosed from January 2011 to December 2013. All patients u...
AIMS We performed a meta-analysis of randomized controlled trials comparing routine stenting (ST) with percutaneous transluminal angioplasty (PTA) for symptomatic superficial femoral-popliteal artery (SFPA) disease. METHODS AND RESULTS Ten trials were pooled randomizing patients to ST (n = 724 limbs) or PTA with provisional stenting (n = 718 limbs) with a follow-up period of 9-24 months. The ...
BACKGROUND Otolaryngology clinics are often booked without considering the distribution of work for doctors and audiologists. This causes inefficiencies of time and human resources. This may be due to clinics being booked before referrals have been triaged to identify whether a hearing test, known as a pure tone audiogram (PTA), is indicated. A model that can predict the need for PTA without cl...
Escherichia coli mutants lacking alcohol dehydrogenase (adh mutants) cannot synthesize the fermentation product ethanol and are unable to grow anaerobically on glucose and other hexoses. Similarly, phosphotransacetylase-negative mutants (pta mutants) neither excrete acetate nor grow anaerobically. However, when a strain carrying an adh deletion was selected for anaerobic growth on glucose, spon...
Pharmaceutical and medical device companies strive to maximize patent term as lengthy development and regulatory review processes precede commercial sales. Most patents internationally receive a standard term of 20 years from the initial application filing date. But US patents frequently receive a longer term, mainly due to patent term adjustment (PTA). PTA offers extra patent term to compensat...
Persistent trigeminal artery (PTA) is one of the remnant fetal anastomoses between the carotid artery and basilar artery. PTAs are classified according to angiographic appearance and various connection. Among them, those directly terminating in the cerebellar arteries are rare subtype. In addition, aneurysms of the PTA are unusual in the literature and have not previously accompanied this subty...
BACKGROUND We investigated the hypothesis that an ultrasound transducer positioned within an angioplasty balloon could be used to perform quantitative assessment of arterial dimensions before and after percutaneous transluminal angioplasty (PTA) and to identify certain mechanical alterations consequent to PTA, including vascular wall recoil and the initiation of plaque fractures. METHODS AND ...
INTRODUCTION Most endovascular techniques are associated with patient and personal exposure to radiation during the procedure. Ionising radiation can cause deterministic effects, such as skin injury, as well as stochastic effects, which increase the long-term risk of malignancy. Endovascular operators need to be aware of radiation danger and take all necessary steps to minimise the risk to pati...
BACKGROUND The prevalence of significant obstructive coronary artery disease with complex lesions is high in patients who have low extremity artery disease (LEAD). However, intermediate- or long-term cardiovascular prognosis of LEAD patients undergoing percutaneous transluminal angioplasty (PTA) remains poor. Accordingly, prophylactic coronary revascularization may modify short- and long-term c...
