BACKGROUND Pleth variability index (PVI) is a new algorithm allowing automated and continuous monitoring of respiratory variations in the pulse oximetry plethysmographic waveform amplitude. PVI can predict fluid responsiveness noninvasively in mechanically ventilated patients during general anesthesia. We hypothesized that PVI could predict the hemodynamic effects of 10 cm H2O positive end-expi...

BACKGROUND Ankle sprains often result in ankle instability, which is most likely caused by damage to passive structures and neuromuscular impairment. Whole body vibration (WBV) is a neuromuscular training method improving those impaired neurologic parameters. The aim of this study is to compare the current gold standard functional treatment to functional treatment plus WBV in patients with acut...

The main objective of this study is to evaluate the impact of maritime transportation instability on international trade instability based on wavelet smoothing and spatial panel data econometric method during the period 1990-2012. The results showed that the spatial effects have an impact on international trade instability. So that a sudden 100 percent increase in international trade in the nei...

OBJECTIVE To provide a rationale for the examination of posture from a dynamic (behavioral) perspective and to relate the vertebral subluxation to postural instability and motion sickness via inefficiency. DATA COLLECTION A manual search of available reference texts and a computer search of literature from Index Medicus, PsycINFO, and ISI Science Citation Index Expanded were collected with an...

conclusion significant functional performance deficits were observed in the fai group in all tests except single hop test with greater deficits observed in the fai-gw group. hence, these tests can be used to determine the presence of fai. however no deficits were identified for the test involving sagittal plane functional activities suggesting that this test can not be used as a criterion to di...

when a jack-up installed at a clay location and then leaves; it can create several meter deep footprints. in case of soft clay, the spudcan may have actually penetrated much deeper than the observed footprints. when the penetrated spudcan is pulled out, much of the soft remolded clay will flow around it and go back into the hole. this event, leaving a deep region of disturbed soil. the disturbe...

Objectives: Traumatic shoulder dislocations in the adolescent, active adult, and elderly have been well studied. However, to our knowledge, no specific study has investigated characteristics outcomes of anterior morbidly obese individuals. The objective this is describe patients with body mass index (BMI) greater than 40. Methods: A retrospective chart review was performed identify 18 years age...

We examine the presence of outliers and time-varying jumps in returns four major cryptocurrencies (Bitcoin, Ethereum, Ripple, Dogecoin, Litecoin), a broad cryptocurrency index (CCI30). The results indicate that only Bitcoin are contaminated with outliers. Time-varying present Bitcoin, Litecoin, index. Notably, is significant after correcting for main findings point to price instability some the...
