abstract background: different adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and elongate the duration and quality of regional blocks. this study was performed to study the effects of one of the adjuvants, verapamil, in supraclavicular block. methods: in this double blinded clinical trial, we divided 60 asa class i and ii patients who were to underg...

background treatment of patients with acute myocardial infarction (ami) is time related, so delay in treatment could affect prognosis. recognizing pre-hospital or in-hospital delays in initiating treatment and reducing these factors is very efficacious in treatment of these patients. results 35.7% patients arrived during one hour of symptom onset, and 7.9% arrived after 24 hours. patients havin...

We propose a novel cross-layer analytic approach to performance evaluation of delay/loss sensitive IP-based applications running over the wireless channels. We firstly extend the small-scale propagation model representing the received signal strength to IP layer using the cross-layer mapping. Then, we replace the resulting IP layer wireless channel model by an artificial equivalent arrival proc...

We propose a covariant algorithm for relativistic ideal measurements and for relativistic continuous measurements, its non-relativistic limit results the algorithm of the Event-Enhanced Quantum Theory. Therefore an additional intrinsic parameter, the proper time, is used. As an application we compute the time of arrival of a particle at a detector and find good agreement between the expected va...

BACKGROUND AND PURPOSE We report on workflow and process-based performance measures and their effect on clinical outcome in Solitaire FR Thrombectomy for Acute Revascularization (STAR), a multicenter, prospective, single-arm study of Solitaire FR thrombectomy in large vessel anterior circulation stroke patients. METHODS Two hundred two patients were enrolled across 14 centers in Europe, Canad...

BACKGROUND AND PURPOSE Successful acute stroke intervention depends on early hospital presentation. Our study aimed to examine the extent of and factors associated with prehospital delays after acute stroke in Taiwan, where people are new to thrombolytic therapy for stroke. METHODS Data were prospectively collected from 196 patients admitted with acute stroke who presented to the emergency de...

 ABSTRACT Background: As any delay in the onset of milk production and ejection in the first few days after delivery can cause breast-feeding failure, this study has been done to determine factors that may affect the onset time of lactation in vaginal and cesarean section deliveries with and without labor pain (elective). Methods: 300 partUJient mothers selected from two private and university ...

PURPOSE The aim of our study was to investigate gender differences in factors related to prehospital delay and identify whether the knowledge of acute myocardial infarction symptoms affects this delay in Korean patients with ST-elevation myocardial infarction (STEMI). MATERIALS AND METHODS A total of 350 patients (286 men, 64 women) with confirmed STEMI were interviewed to investigate socio-d...

background and aim: this study investigated whether objective temporal processing paradigms including voice-onset-time, speech-in-noise, and amplitude modulated-broad-band noise (am-bbn) are sensitive to disrupted temporal processing in elderly listeners with normal hearing (age-related-temporal processing deficit). methods: we evaluated 15 adults aged 64–80 years using behavioural measures of ...
