BACKGROUND AND PURPOSE In acute stroke, the DWI-FLAIR mismatch allows for the allocation of patients to the thrombolysis window (<4.5 hours). FLAIR-lesions, however, may be challenging to assess. In comparison, DWI may be a useful bio-marker owing to high lesion contrast. We investigated the performance of a relative DWI signal intensity (rSI) threshold to predict the presence of FLAIR-lesions ...

Given a frequency-selective fading channel, feedback can be used to convey Channel State Information (CSI) and Receiver State Information (RSI) to the transmitter. RSI refers to information about the receiver’s estimate of the message, which can be used to improve reliability, e.g., through retransmissions. This paper studies the trade-off between these two types of feedback under total feedbac...

OBJECTIVES In a video-based study of rapid sequence intubation (RSI) in a pediatric emergency department (PED), 33% of children experienced oxyhemoglobin desaturation (SpO2 < 90%). To inform targeted improvement interventions, we planned multivariable analyses to identify patient and process variables (including time-based data around performance of key RSI process elements uniquely available f...

BACKGROUND Emergency rapid sequence intubation (RSI) performed outside the operating room on emergency patients is the cornerstone of emergency airway management. Complication rates are unknown for this procedure in the United Kingdom and the factors contributing to immediate complications have not been identified. AIMS To quantify the immediate complications of RSI and to assess the contribu...

PURPOSE To translate and cross-culturally adapt the anterior cruciate ligament-return to sport after injury (ACL-RSI) into simplified Chinese [ACL-RSI (Cn)]. METHOD In this diagnostic study, the translation, cross-culturally adaptation, and validation of the ACL-RSI was performed according to international guidelines. A total of 112 patients with ACL reconstruction participated in this study....

STUDY OBJECTIVE Using video review, we seek to determine the frequencies of first-attempt success and adverse effects during rapid sequence intubation (RSI) in a large, tertiary care, pediatric emergency department (ED). METHODS We conducted a retrospective study of children undergoing RSI in the ED of a pediatric institution. Data were collected from preexisting video and written records of ...

Through the use of double task conditions, the sequence learning (SL) paradigm offers unique opportunities to study the relationships between learning and attention. In their original study, Nissen & Bullemer (1987) argued that a secondary tone-counting task prevents SL because it exhausts participants’ attentional resources. Other authors have instead suggested that the detrimental effects of ...

The purpose of this study was to determine if an appropriate drop jump height for female athletes could be determined from squat and/or power clean maximums. Thirteen female collegiate basketball or volleyball players had their appropriate drop jump height determined by both maximal jump height (MJH) and reactive strength index (RSI) methods. The two methods often determined different appropria...

OBJECTIVES Rapid sequence intubation (RSI) is the standard for definitive airway management in emergency medicine. In a video-based study of RSI in a paediatric emergency department (ED), we reported a high degree of process variation and frequent adverse effects, including oxyhaemoglobin desaturation (SpO2<90%). This report describes a multidisciplinary initiative to improve the performance an...

The literature on Regional Systems of Innovation (RSI) has produced an extensive body of research in recent years and has been used widely as a framework for the design and implementation of policies in a variety of regional contexts. However, certain lack of clarity remains in relation to the defining elements and the dynamics of RSI. This lack of clarity is motivated by the fact that the conc...
